PMID- 29566241 TI - PUBLIC EXPOSURE TO MULTIPLE RF SOURCES IN GHANA. AB - This paper describes an effort to respond to the suggestion in World Health Organization (WHO) research agenda to better quantify potential exposure levels from a range of radiofrequency (RF) sources at 200 public access locations in Ghana. Wide-band measurements were performed-with a spectrum analyser and a log periodic antenna using three-point spatial averaging method. The overall results represented a maximum of 0.19% of the ICNIRP reference levels for public exposure. These results were generally lower than found in some previous but were 58% (2.0 dB) greater, than found in similar work conducted in the USA. Major contributing sources of RF fields were identified to be FM broadcast and mobile base station sites. Three locations with the greatest measured RF fields could represent potential areas for epidemiological studies.

AB - Objectives: A growing literature acknowledges the association between childhood socioeconomic status (SES) and health in late adulthood (i.e., 50+). Less, however, is known about the association with mental health outcomes, such as depression. We use the Survey on Health, Ageing and Retirement in Europe (SHARE) to analyse overall and gender-specific associations between childhood SES and late-adulthood depression. Methods: Using life-history and contemporaneous data from 21,989 SHARE respondents in combination with principal component analysis we construct indices of childhood SES. We measure late-adulthood depression using the EURO-D scale. Contemporaneous SES is operationalized as the logarithm of household equivalised income. We estimate associations using linear regression models. Results: We document a positive association between childhood SES and the late-adulthood EURO-D score. The association persists even when allowing for contemporaneous SES. Zooming in on gender-specific associations reveals that the association for mental health is particularly pronounced for women. Discussion: Our findings reveal the long-term association between childhood socioeconomic conditions and depression later in life, which persists even after taking into account current socioeconomic conditions and are stronger for women than for men. These results imply that boosting childhood socioeconomic conditions can potentially have effects lasting well beyond the childhood phase.

AB - Discovery of monoclonal antibodies is most commonly performed using phage or yeast display but mammalian cells are used for production because of the complex antibody structure, including the multiple disulfide bonds and glycosylation, required for function. As this transition between host organisms is often accompanied by impaired binding, folding or expression, development pipelines include laborious plate-based screening or engineering strategies to adapt an antibody to mammalian expression. To circumvent these problems, we developed a plasmid-based Fab screening platform on Chinese hamster ovary (CHO) cells which allows for antibody selection in the production host and in the presence of the same post-translational modifications as the manufactured product. A hu4D5 variant with low affinity for the human epidermal growth factor receptor (HER2) growth factor receptor was mutagenized and this library of ~106 unique clones was screened to identify variants with up to 400-fold enhanced HER2 binding. After two rounds of fluorescence activated cell sorting (FACS), four unique clones exhibited improved antigen binding when expressed on the CHO surface or as purified human IgG. Three of the four clones contained free cysteines in third complementarity determining region of the antibody heavy chain, which did not impair expression or cause aggregation. The improved clones had similar yields and stabilities as hu4D5 and similar sub-nanomolar affinities as measured by equilibrium binding to target cells. The limited size of mammalian libraries restricts the utility of this approach for naive antibody library screening, but it is a powerful approach for antibody affinity maturation or specificity enhancement and is readily generalizable to engineering other surface receptors, including T-cell receptors and chimeric antigen receptors.

AB - Limiting nitrogen (N) supply contributes to improved resistance to bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) in susceptible rice (Oryza sativa). To understand the regulatory roles of microRNAs (miRNAs) in this phenomenon, 63 differentially expressed overlapping miRNAs in response to Xoo infection and N limitation stress in rice were identified through deep RNA sequencing and stem-loop quantitative real-time PCR. Among these, miR169o was further assessed as a typical overlapping miRNA through the overexpression of the miR169o primary gene. Osa-miR169o-OX plants were taller, and had more biomass accumulation with significantly increased nitrate and total amino acid contents in roots than the wild type (WT). Transcript level assays showed that under different N supply conditions, miR169o oppositely regulated NRT2, and this is reduced under normal N supply conditions but remarkably induced under N-limiting stress. On the other hand, osa-miR169o-OX plants also displayed increased disease lesion lengths and reduced transcriptional levels of defense gene (PR1b, PR10a, PR10b and PAL) compared with the WT after inoculation with Xoo. In addition, miR169o impeded Xoo-mediated NRT transcription. Therefore, the overlapping miR169o contributes to increase N use efficiency and negatively regulates the resistance to BB in rice. Consistently, transient expression of NF-YA genes in rice protoplasts promoted the transcripts of PR genes and NRT2 genes, while it reduced the transcripts of NRT1 genes. Our results provide novel and additional insights into the co ordinated regulatory mechanisms of cross-talk between Xoo infection and N deficiency responses in rice. PMID- 29566244 TI - Activating Aging Stereotypes Increases Source Recollection Confusions in Older Adults: Effect at Encoding but Not Retrieval. AB - Objectives: Activating aging stereotypes can impair older adult performance on episodic memory tasks, an effect attributed to stereotype threat. Here, we report the first study comparing the effects of explicitly activating aging stereotypes at encoding versus retrieval on recollection accuracy in older adults. Method: During the encoding phase, older adults made semantic judgments about words, and during the retrieval phase, they had to recollect these judgments. To manipulate stereotype activation, participants read about aging-related decline (stereotype condition) or an aging-neutral passage (control condition), either before encoding or after encoding but before retrieval. We also assessed stereotype effects on metacognitive beliefs and two secondary tasks (working memory, general knowledge) administered after the recollection task. Results: Stereotype activation at encoding, but not retrieval, significantly increased recollection confusion scores compared to the control condition. Stereotype activation also increased self-reports of cognitive decline with aging, but it did not reliably impact task-related metacognitive assessments or accuracy on the secondary tasks. Discussion: Explicitly activating aging stereotypes at encoding increases the likelihood of false recollection in older adults, potentially by diminishing encoding processes. Stereotype activation also influenced global metacognitive assessments, but this effect may be unrelated to the effect of stereotypes on recollection accuracy.

PMID- 29566246 TI - Efficacy and Safety of Glecaprevir/Pibrentasvir in Patients Coinfected With Hepatitis C Virus and Human Immunodeficiency Virus Type 1: The EXPEDITION-2 Study. AB - Background: Once-daily glecaprevir coformulated with pibrentasvir (glecaprevir/pibrentasvir) demonstrated high rates of sustained virologic response 12 weeks after treatment (SVR12) in patients with hepatitis C virus (HCV) genotype 1-6 infection. This phase 3 study evaluated the efficacy and safety of glecaprevir/pibrentasvir in patients with chronic HCV genotype 1-6 and human immunodeficiency virus type 1 (HIV-1) coinfection, including patients with compensated cirrhosis. Methods: EXPEDITION-2 was a phase 3, multicenter, open label study evaluating glecaprevir/pibrentasvir (300 mg/120 mg) in HCV genotype 1 6/HIV-1-coinfected adults without and with compensated cirrhosis for 8 and 12 weeks, respectively. Patients were either HCV treatment-naive or experienced with sofosbuvir, ribavirin, or interferon, and antiretroviral therapy (ART) naive or on a stable ART regimen. Treatment-experienced genotype 3-infected patients were excluded. The primary endpoint was the SVR12 rate. Results: In total, 153 patients were enrolled, including 16 (10%) with cirrhosis. The SVR12 rate was 98% (n = 150/153; 95% confidence interval, 95.8-100), with no virologic failures in 137 patients treated for 8 weeks. One genotype 3-infected patient with cirrhosis had on-treatment virologic failure. Most adverse events were mild in severity; 4 patients (2.6%) had serious adverse events, all deemed unrelated to glecaprevir/pibrentasvir. Treatment discontinuation was rare (<1%). All patients treated with ART maintained HIV-1 suppression (<200 copies/mL) during treatment. Conclusions: Glecaprevir/pibrentasvir for 8 weeks in noncirrhotic and 12 weeks in cirrhotic patients is a highly efficacious and well-tolerated treatment for HCV/HIV-1 coinfection, regardless of baseline HCV load or prior treatment with interferon or sofosbuvir.

AB - Most Mendelian disorders, including neuromuscular disorders, display extensive clinical heterogeneity that cannot be solely explained by primary genetic mutations. This phenotypic variability is largely attributed to the presence of disease modifiers, which can exacerbate or lessen the severity and progression of the disease. LAMA2-deficient congenital muscular dystrophy (LAMA2-CMD) is a fatal degenerative muscle disease resulting from mutations in the LAMA2 gene encoding Laminin-alpha2. Progressive muscle weakness is predominantly observed in the lower limbs in LAMA2-CMD patients, whereas upper limbs muscles are significantly less affected. However, very little is known about the molecular mechanism underlying differential pathophysiology between specific muscle groups. Here, we demonstrate that the triceps muscles of the dy2j/dy2j mouse model of LAMA2-CMD demonstrate very mild myopathic findings compared with the tibialis anterior (TA) muscles that undergo severe atrophy and fibrosis, suggesting a protective mechanism in the upper limbs of these mice. Comparative gene expression analysis reveals that S-Adenosylmethionine decarboxylase (Amd1) and Spermine oxidase (Smox), two components of polyamine pathway metabolism, are downregulated in the TA but not in the triceps of dy2j/dy2j mice. As a consequence, the level of polyamine metabolites is significantly lower in the TA than triceps. Normalization of either Amd1 or Smox expression in dy2j/dy2j TA ameliorates muscle fibrosis, reduces overactive profibrotic TGF-beta pathway and leads to improved locomotion. In summary, we demonstrate that a deregulated polyamine metabolism is a characteristic feature of severely affected lower limb muscles in LAMA2-CMD. Targeted modulation of this pathway represents a novel therapeutic avenue for this devastating disease. PMID- 29566248 TI - Prevalence of sensitization to Aspergillus flavus in patients with allergic bronchopulmonary aspergillosis. AB - Aspergillus fumigatus is the most common Aspergillus species worldwide; however, A. flavus has also been shown to be prevalent in North India. Herein, we investigate the prevalence of sensitization to A. flavus in subjects with allergic bronchopulmonary aspergillosis (ABPA). We also evaluate the occurrence of allergic bronchopulmonary mycosis (ABPM) due to A. flavus. Treatment-naive subjects with ABPA underwent sputum culture; and, skin testing, fungal-specific immunoglobulin E (IgE) and serum precipitation tests for A. fumigatus and A. flavus. Sensitization to A. flavus was diagnosed if any immunological test for A. flavus was positive in subjects with ABPA. ABPM was labelled as probable if sputum cultures grew A. flavus and A. flavus-specific IgE was greater than A. fumigatus-specific IgE; and, possible if only A. flavus-specific IgE was greater than A. fumigatus-specific IgE. Fifty-three subjects with a mean (SD) age of 34.2 (12.8) years were included. Sensitization to A. flavus was seen in 51 (96.2%) subjects, with overlap occurring in 49 (92.5%), 21 (39.6%), and 12 (22.6%) instances on fungal-specific IgE, skin prick test and precipitins, respectively. Sputum culture was positive in 18 (33.9%; A. flavus [n = 12], A. fumigatus [n = 6]) subjects. ABPM due to A. flavus was diagnosed in 16 (30.2%) subjects (10 probable, 6 possible). They were more likely to have high-attenuation mucus and a trend towards higher occurrence of sinusitis, compared to ABPA. We found a high occurrence of sensitization to A. flavus in subjects with ABPA. Subjects with A. flavus-related ABPM had a higher likelihood of high-attenuation mucus and probability of sinusitis. More studies are required to confirm this observation. PMID- 29566249 TI - Molecular characterization of Leishmania infantum isolates in municipalities of the state of Minas Gerais, Brazil.

It also permits physiological weight bearing, improved range of motion in the proximal joint, and osseoperceptive sensor feedback, enabling better control of the artificial limb by amputees. This article describes the osseointegration program in Sweden based on the use of bone anchored prostheses for transfemoral amputation rehabilitation. The authors discuss in detail the patient-centered evaluation, surgical technique, and postoperative rehabilitation protocol. The outcomes of a prospective study of transfemoral amputees using the bone-anchored prostheses are presented. [Orthopedics. 2018; 41(2):75-80.]. PMID- 29566254 TI - New insights into the pathophysiology of inflammatory bowel disease: microbiota, epigenetics and common signalling pathways. AB - The exact pathophysiology of inflammatory bowel disease (IBD) is still unknown. However, over the years important insights allowed the development of novel therapeutic approaches that are at the threshold of introduction into clinical practice, or at least in clinical trials. After being first described by Burrill B. Crohn, Crohn's disease, one of the two major forms of IBD, was perceived as an infectious disease. When the concept of autoimmune diseases was formulated, Crohn's disease and ulcerative colitis were thought to be members of this disease group. T cells certainly contribute to the chronification of the intestinal inflammation and targeting T cell migration has been introduced some years ago as a successful therapeutic approach in IBD. Despite the development of successful therapy based on this pathophysiological concept, IBD is no longer seen as a typical autoimmune disease. After the millennium, genome wide association studies on genetic variants and risk factors in these polygenetic diseases have told us a lot about pathogenetic pathways. However, genetic susceptibility explains only up to one third of the cases. Environmental factors also must play a role. Those environmental factors may "transfer" their disease-promoting potential into pathophysiological pathways with the intestinal microbiota as mediator. Hence, the intestinal microbiota has gained much attention as an important factor in disease development. Microbial factors, as well as other direct environmental influences, have been shown to affect epigenetic signatures, intestinal epithelial cells and the innate immune system, providing another important concept on how these diseases originate and can cause repeated flares at the same gut segments even after years of remission and after intermediate complete mucosal healing. Current pathophysiological concepts of IBD not only help us to better understand these diseases and develop new therapies. They also illustrate the evolution of basic scientific concepts over time and that sometimes partially or even largely abandoned concepts persistently influence out current thinking/clinical practice. PMID- 29566255 TI - The bZip transcription factor HY5 mediates CRY1a-induced anthocyanin biosynthesis in tomato. AB - The production of anthocyanin is regulated by light and corresponding photoreceptors. In this study, we found that exposure to blue light and overexpression of CRY1a are associated with increased accumulation of anthocyanin in tomato (Solanum lycopersicum L.). These responses are the result of changes in mRNA and the protein levels of SlHY5, which is a transcription factor. In vitro and in vivo experiments using electrophoretic mobility shift assay and ChIP-qPCR assays revealed that SlHY5 could directly recognize and bind to the G-box and ACGT-containing element in the promoters of anthocyanin biosynthesis genes, such as chalcone synthase 1, chalcone synthase 2, and dihydroflavonol 4-reductase. Silencing of SlHY5 in OE-CRY1a lines decreased the accumulation of anthocyanin. The findings presented here not only deepened our understanding of how light controls anthocyanin biosynthesis and associated photoprotection in tomato leaves, but also allowed us to explore potential targets for improving pigment production. PMID- 29566256 TI - Caregivers experiences of nursing care for relatives hospitalized during manic episode: A phenomenological study. AB - PURPOSE: To describe the experiences of informal caregivers with the nursing care received by relatives hospitalized for mania. DESIGN AND METHODS: Multicenter phenomenological study using open interviews. Data were analyzed using the Stevick-Colaizzi-Keen method. FINDINGS: The essence of the experiences was the importance of communication, about being informed and involved in treatment during hospitalization of their relative. The experiences depended on the nature of the relation between participant and relative. PRACTICE IMPLICATIONS: Nurses should listen to caregivers' experiences, inquire about the expectations of caregivers regarding nursing care, and advise informal caregivers on how to take care of their relatives. PMID- 29566257 TI - Seven additional families with spondylocarpotarsal synostosis syndrome with novel biallelic deleterious variants in FLNB. AB - The location and/or type of variants in FLNB result in a spectrum of osteochondrodysplasias ranging from mild forms, like spondylocarpotarsal synostosis syndrome and Larsen syndrome, to severe perinatal lethal forms, such as atelosteogenesis I and III and Boomerang dysplasia. Spondylocarpotarsal synostosis syndrome is characterized by disproportionate short stature, vertebral anomalies and fusion of carpal and tarsal bones. Biallelic loss-of-function variants in FLNB are known to cause spondylocarpotarsal synostosis syndrome and 9 families and 9 pathogenic variants have been reported so far. We report clinical features of 10 additional patients from 7 families with spondylocarpotarsal synostosis syndrome due to 7 novel deleterious variants in FLNB, thus expanding the clinical and molecular repertoire of spondylocarpotarsal synostosis syndrome. Our report validates key clinical (fused thoracic vertebrae and carpal and tarsal coalition) and molecular (truncating variants in FLNB) characteristics of this condition.

Somali new mothers' childbirth experiences in Norway and the United States. AB - BACKGROUND: Due to civil war, Somalis immigrants have settled in Norway and the United States. Large families are valued among Somalis and Somali women continue to give birth in their new countries. Research studies have been conducted with Somali immigrant new mothers in Norway and Minnesota, United States to understand perceptions of their childbirth experience. PURPOSE: The purpose of this qualitative study was to compare the childbirth experiences of Somali immigrant mothers in the United States and Norway to make recommendations to improve health care practice. DESIGN: This paper presents a comparison of two research studies in order to identify and explain similarities and differences between cross cultural immigrant populations. RESULTS: Both studies identified themes related to the importance of family support in the postpartum period, fear of Cesarean delivery, and relationships with nurses. These studies give recommendations for nurses on how to provide culturally sensitive care for Somali new mothers. CONCLUSIONS: Implications for practice are that nurses should develop trusting relationships with Somali mothers and facilitate cultural and religious practices. Information regarding support resources in the community should be provided to Somali mothers throughout the perinatal period.

AB - The long QT syndrome (LQTS) is a channelopathy that can lead to severe arrhythmia and sudden cardiac death. Pharmacologically induced LQTS is caused by interaction between drugs and potassium channels, especially the Kv 11.1 channel. Due to such interactions, numerous drugs have been withdrawn from the market or are administered with precautions in human medicine. However, some compounds, such as trimethoprim-sulfonamide combinations are still widely used in veterinarian medicine. Therefore, we investigate the effect of trimethoprim-sulfadiazine (TMS), trimethoprim, sulfadiazine, and detomidine on equine-specific Kv 11.1 channels. Kv 11.1 channels cloned from equine hearts were heterologously expressed in Xenopus laevis oocytes, and whole cell currents were measured by two electrode voltage-clamp before and after drug application. TMS blocked equine Kv 11.1 current with an IC50 of 3.74 mm (95% CI: 2.95-4.73 mm) and affected the kinetics of activation and inactivation. Similar was found for trimethoprim but not for sulfadiazine, suggesting the effect is due to trimethoprim. Detomidine did not affect equine Kv 11.1 current. Thus, equine Kv 11.1 channels are also susceptible to pharmacological block, indicating that some drugs may have the potential to affect repolarization in horse. However, in vivo studies are needed to assess the potential risk of these drugs to induce equine LQTS. PMID- 29566262 TI - Regulatory T cells: a potential target in cancer immunotherapy. AB - Cancer immunotherapy involving blockade of immune checkpoint molecules, such as CTLA-4 and PD-1, has shown remarkable clinical success across several types of malignancies. However, a fraction of patients experience disease progression after treatment; thus, exploring resistant mechanisms for immune checkpoint inhibitors and improving their treatment outcome with additional modalities are of great importance. CD4+ regulatory T (Treg ) cells characterized by expression of the master regulatory transcription factor FOXP3 are a highly immune suppressive subset of CD4+ T cells that maintain immune homeostasis. Several preclinical and clinical studies suggest that Treg cells hamper immune surveillance against cancer in healthy individuals, prevent the development of effective antitumor immunity in tumor-bearing patients, and promote tumor progression. Therefore, targeting Treg cells should be crucial to improving the treatment outcomes of cancer immunotherapy. Several clinical studies directly or indirectly targeting Treg cells in combination with immune checkpoint inhibitors are ongoing or being planned. Understanding the characteristics and roles of Treg cells in cancer settings could make disease-specific Treg -targeted therapy more efficacious and reduce the incidence of immune-related adverse effects mediated by Treg cell inhibition. PMID- 29566263 TI - Comparison of vesical pressure values achieved by Valsalva maneuvers: A standardization proposal. AB - AIMS: To perform a comparative evaluation of Valsalva maneuver techniques, in an attempt to identify the most suitable one for achieving leak point pressure (LPP) during the cystometric phase of the urodynamic study (UDS), in order to propose a method for technical standardization. METHODS: Urodynamic data from women with stress urinary incontinence at three urogynecological medical centers were randomly selected and prospectively analyzed. Valsalva maneuver was executed through forceful attempted exhalation against the dorsal surface of the hand (Group 1), through abdominal strain (Group 2), or through low-elasticity latex balloon-blowing (Group 3). Patients were classified based on age and higher vesical pressure value, as well as time to perform Valsalva maneuver. RESULTS: Initially, 1358 urodynamic studies were identified as eligible for analysis. Among these, 340 belonged to Group 1, 318 to Group 2, and 700 to Group 3. Valsalva maneuver accomplished through abdominal straining was more effective, inducing increased vesical pressure, across age groups. The same maneuver may be sustained for longer than the other two techniques. CONCLUSION: When performed through abdominal strain, the Valsalva maneuver was more effective for stress urinary incontinence urodynamic's investigation. PMID- 29566264 TI - The effects of cystoscopy and hydrodistention on symptoms and bladder capacity in interstitial cystitis/bladder pain syndrome. AB - AIMS: The use of cystoscopy and hydrodistention in the management of interstitial cystitis/bladder pain syndrome (IC/BPS) varies widely between providers. Current evidence regarding the risks and benefits of hydrodistention, as well as the long term effects of repeated hydrodistention are not well established. We sought to characterize the effects of hydrodistention on IC/BPS symptoms as well as bladder capacity. METHODS: We retrospectively queried our institutional records for patients with non-ulcerative IC/BPS who underwent hydrodistention over an 11-year period to obtain demographic and clinical factors at the time of diagnosis and treatment. Symptom relief and bladder capacity changes were assessed, and multivariable models were used to predict response to treatment. RESULTS: There were 328 patients who underwent hydrodistention during the study period, of whom 36% received the procedure multiple times, and overall median follow-up was 38.6 months. Patients with repeated hydrodistentions were more likely to be female, have more comorbid pain disorders, and have trialed anticholinergic medications and intravesical instillations. No decrease in mean bladder capacity was observed over time (P = 0.40). Significant decreases in symptom scores were observed following the procedure on multiple questionnaires. CONCLUSIONS: Hydrodistention does not decrease bladder capacity even with multiple procedures, and measurably improves symptoms in some patients with IC/BPS. Continuing efforts to better identify those patients most likely to benefit from this procedure are justified. PMID- 29566265 TI - Long-term functional outcome analysis in a large cohort of patients after radical prostatectomy. AB - INTRODUCTION: Goal of the study was an analysis of functional outcomes after radical prostatectomy (RP) in a large cohort of patients. METHODS: Functional outcomes were assessed with the ICIQ-SF questionnaire and daily pad-usage for the evaluation of stress urinary incontinence (SUI) as well as with the IIEF-5 score for the evaluation of erectile dysfunction (ED). Statistical analysis included log-rank test, Mann-Whitney-Test, ANOVA test and logistic regression (P < 0.05). RESULTS: In total 4003 patients were included in the study. Median follow-up was 42 months (min. 2-max. 147 mo.). Regarding ED, an IIEF-5 score of >=20 was reached by 39% of patients. Regarding SUI, 55% stated that they needed no pads, 21% of patients needed one pad per day. 33% of patients reported of no incontinence (0 p. in ICIQ), 26% of patients reported of a mild incontinence (1-5 p. in ICIQ). Patients global impression of their overall health respectively patients subjective quality of life were assessed with the EORTC QLC-C30 and were both high with a median of six points (on a scale of 1-7). In multivariate analysis time since surgery could be identified as independent risk factors on QOL (P = 0.0028), IIEF-5 (P = 0.0149), ICIQ (P < 0.001), and pads per day (P < 0.001). CONCLUSIONS: Our data show a good continence status, a clearly impaired erectile function but overall a good quality of life after surgery. In summary older patients-with an advanced tumor and adjuvant radiation therapy-were at highest risk for an impaired functional outcome. PMID- 29566266 TI - A Computational Model of the Self-Teaching Hypothesis Based on the Dual-Route Cascaded Model of Reading. AB - The self-teaching hypothesis describes how children progress toward skilled sight word reading. It proposes that children do this via phonological recoding with assistance from contextual cues, to identify the target pronunciation for a novel letter string, and in so doing create an opportunity to self-teach new orthographic knowledge. We present a new computational implementation of self teaching within the dual-route cascaded (DRC) model of reading aloud, and we explore how decoding and contextual cues can work together to enable accurate self-teaching under a variety of circumstances. The new model (ST-DRC) uses DRC's sublexical route and the interactivity between the lexical and sublexical routes to simulate phonological recoding. Known spoken words are activated in response to novel printed words, triggering an opportunity for orthographic learning, which is the basis for skilled sight-word reading. ST-DRC also includes new computational mechanisms for simulating how contextual information aids word identification, and it demonstrates how partial decoding and ambiguous context interact to achieve irregular-word learning. Beyond modeling orthographic learning and self-teaching, ST-DRC's performance suggests new avenues for empirical research on how difficult word classes such as homographs and potentiophones are learned.

AB - AIMS: To investigate the localization of phosphodiesterase 5 (PDE5) and the molecular mechanism underlying the effect of the PDE5 inhibitor tadalafil in signal transduction in the bladder urothelium. METHODS: PDE5 expression in rat bladder tissues and cultured primary rat bladder urothelial cells was evaluated using immunochemistry and western blot assays. Ca2+ influx in cells exposed to isotonic solution, hypotonic solution, a selective transient receptor potential vanilloid 2 (TRPV2) channel agonist (cannabidiol), a selective TRPV4 channel agonist (GSK1016790A), a TRP cation channel melastatin 7 (TRPM7) channel agonist (PIP2), or a purinergic receptor agonist (ATP) in the presence or absence of 10 uM tadalafil was evaluated using calcium imaging techniques. We also evaluated stretch-induced changes in ATP concentration in the mouse bladder in the presence or absence of 100 uM tadalafil. RESULTS: Immunochemistry and western blot analyses demonstrated that PDE5 is abundantly expressed in the bladder urothelium and in primary rat urothelial cells. Ca2+ influx induced by hypotonic stimulation, GSK1016790A, or cannabidiol was significantly inhibited by tadalafil, whereas ATP-induced Ca2+ influx was unaffected by tadalafil. PIP2 did not induce Ca2+ influx. ATP release in tadalafil-pretreated bladders significantly decreased compared to control bladders. CONCLUSIONS: Tadalafil attenuates Ca2+ influx via TRPV4 and TRPV2, and inhibits ATP release in the bladder urothelium. These findings indicate that tadalafil functions as an inhibitor of urothelial signal transduction. PMID- 29566268 TI - Nonfluoroscopic catheter ablation of paroxysmal atrial fibrillation. AB - AIMS: Radiofrequency catheter ablation of atrial fibrillation (AF) is one of the most complex ablation procedures. Both patients and operators are exposed to scattered radiation. This study evaluated the safety and efficacy of intracardiac echo (ICE)-guided pulmonary vein isolation (PVI) without fluoroscopy. METHODS: We retrospectively analyzed the data of 481 consecutive patients with paroxysmal AF undergoing radiofrequency PVI with the CARTO 3 system (Biosense Webster, Diamond Bar, CA, USA). ICE-guided PVI without fluoroscopy and without CT/MRI integration (Nonfluoro group) was performed for 245 patients, and conventional fluoroscopy guided PVI (Fluoro group) was performed for 236 patients. The primary safety endpoint was the incidence of major adverse events. The primary efficacy endpoint was freedom from AF during follow-up. Secondary endpoints included procedure duration, fluoroscopy duration, and acute PVI rate. RESULTS: Mean procedure times between groups were similar (108.8 +/- 18.2 minutes in the Non-fluoro group vs 113.6 +/- 26.8 minutes in the Fluoro group; P = not significant [NS]). Acute PVI was achieved in all patients, with mean radiofrequency application times of 43.4 +/- 7.5 and 44.4 +/- 10.7 minutes for the Nonfluoro and Fluoro groups, respectively (P = NS). The incidence of cardiac tamponade was 1.2% (3/245 patients) in the Nonfluoro group and 0.8% (2/236 patients) in the Fluoro group (P = NS). During 15.2 +/- 4.1 months of follow-up, after a single procedure, AF recurrence was documented in 65 of 245 (26.5%) patients and 61 of 236 (25.8%) patients in the Nonfluoro and Fluoro groups, respectively (P = NS). CONCLUSIONS: Nonfluoroscopic ICE-guided catheter ablation of AF without prior cardiac image integration or angiography is feasible and safe. PVI without fluoroscopy did not affect procedure duration or long-term efficacy.

AB - AIMS: This study describes development of the Impact of Nighttime Urination (INTU) questionnaire to assess nocturia impacts on health and functioning. METHODS: Development of the questionnaire followed an iterative patient-directed process as recommended by current guidance for patient-reported outcome (PRO) measures. An initial 15-item questionnaire was devised based on reviewing the published literature, and then modified through four rounds of semi-structured interviews of 28 individuals with nocturia. In each round, open-ended concept elicitation, followed by cognitive debriefing, was used to assess the questionnaire. Items were modified based on participants' responses and incorporated into the next round of interviews. RESULTS: In all rounds, participants reported that their experiences were easy to recall and report on a daily basis and that the burden of completing the questionnaire was low. The final questionnaire has a same-day recall period. It includes six daytime impact items-having limited concentration, a sense of feeling tired, difficulty getting things done, irritability, not feeling rested, and drowsiness-and four items that measure the nighttime impact of nocturia-patient concern, waking up too early, difficulty getting enough sleep, and feeling bothered by having to get up at night to void. Responses follow a 5- or 4-point scale. The final INTU captures the key concepts associated with nocturia as confirmed by cognitive debriefing. CONCLUSIONS: Development of the 10-item INTU, a nocturia-specific PRO measure, was based on direct input and feedback from patients and has demonstrated that it captures the patient-reported impacts of nocturia. PMID- 29566270 TI - A customized approach for arm fat reduction using cryolipolysis. AB - OBJECTIVES: Cryolipolysis of the arms has been demonstrated to be an effective treatment for non-invasive reduction of subcutaneous fat. This study evaluated the safety and efficacy of the concurrent use of a new commercially-available small applicator in conjunction with an existing medium sized applicator for the customized treatment of arm fat. METHODS: Bilateral arms of 15 eligible subjects were simultaneously treated using one or two vacuum applicators with flat contours. Either a medium or small cryolipolysis applicator with an oblong cup shaped cooling surface was selected to treat upper arm fat. The shape of the fat bulge in each subject's arm was assessed and up to two treatment cycles (-11 degrees C for 35 minutes each) were delivered to each arm in one session, based upon investigator discretion. Throughout the procedure and at the completion of each treatment cycle, investigators assessed the subject's level of comfort, as well as sensory and motor nerve effects. Post-treatment manual massage was performed, and clinical assessments of each treatment site were recorded. Adverse events were recorded to monitor procedural safety. Baseline and 12 weeks post treatment photographs and ultrasound measurements were taken to assess efficacy. Subject questionnaires were administered to evaluate satisfaction. RESULTS: Fifteen female subjects (mean age of 51.1, mean BMI of 26.8) completed the study. Ultrasound imaging revealed statistically significant fat layer reduction of 2.5 mm (SD +/- 2.4 mm, 95%CI 1.6-3.3). Subject surveys administered 12 weeks post treatment demonstrated 87% satisfaction with the arm cryolipolysis procedure. A panel of blinded, independent physicians correctly identified 83% of the before and after photos. Clinical assessments found adverse events were mild and included erythema and mild swelling that resolved without intervention. Mild treatment area numbness was reported by 73% of subjects at the 4-week interim visit and fully resolved at the 12-week visit. CONCLUSION: This study documents the first reported customized approach for assessment and treatment of arm fat using a small or medium cup applicator with varied applicator placement. By incorporating one or two treatment cycles per arm in a single session, the issue of variable fat distribution in people's arms can be addressed. This approach was shown to be a safe and effective way to reduce unwanted arm fat with high patient satisfaction. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc. PMID- 29566271 TI - Lessons learned from using an audience response system in a community setting for research data collection. AB - OBJECTIVES: A community-academic team implemented a study involving collection of quantitative data using a computer-based audience response system (ARS) whereby community partners led data collection efforts. The team participated in a reflection exercise after the data collection to evaluate and identify best practices and lessons learned about the community partner-led process. DESIGN & SAMPLE: The methods involved a qualitative research consultant who facilitated the reflection exercise that consisted of two focus groups-one academic and one community research team members. The consultant then conducted content analysis. Nine members participated in the focus groups. RESULTS: The reflection identified the following themes: the positive aspects of the ARS; challenges to overcome; and recommendations for the future. CONCLUSION: The lessons learned here can help community-academic research partnerships identify the best circumstances in which to use ARS for data collection and practical steps to aid in its success. PMID- 29566272 TI - Association between lifetime risk of atrial fibrillation and mortality in the oldest old. AB - BACKGROUND: Age is the strongest predictor of atrial fibrillation (AF), yet little is known about AF incidence in the oldest old. HYPOTHESIS: AF incidence declines after age 90 years, and morbidity is compressed into a brief period at the end of life. METHODS: In this retrospective, longitudinal cohort study of patients (born 1905-1935), we examined cumulative lifetime incidence of AF and its impact on mortality. Data included records from 1 062 610 octogenarians, 317 161 nonagenarians, and 3572 centenarians. Kaplan-Meier curves were used to estimate cumulative incidence of AF by age group, incidence rates were compared using log-rank tests, and Cox proportional hazards model was used to estimate unadjusted hazard ratios. The primary outcome was AF incidence at age > 80 years; the secondary outcome was mortality. RESULTS: The cumulative AF incidence rate was 5.0% in octogenarians, 5.4% in nonagenarians, and 2.3% in centenarians. Octogenarians and nonagenarians had a higher risk of AF incidence compared to centenarians (adjusted hazard ratio 8.74, 95% confidence interval [CI]: 6.31 12.04; and 2.98, 95% CI: 2.17-4.1, respectively). The lowest hazard ratio for mortality in patients with AF compared to those without was 2.3 (95% CI: 2.3-2.4) in patients who were on antiplatelet and anticoagulant medication and had a score of 0 on the Elixhauser comorbidity index score. CONCLUSIONS: Although AF incidence increased with age, being a centenarian was associated with reduced incidence and compression of morbidity. Patients with AF had a higher adjusted mortality rate. However, data suggest that a regimen of anticoagulants and antiplatelets may reduce risk of mortality in patients over 80 with an AF diagnosis. PMID- 29566273 TI - Appropriate use criteria in dermatopathology: Initial recommendations from the American Society of Dermatopathology. AB - BACKGROUND: Appropriate use criteria (AUC) provide physicians guidance in test selection, and can affect health care delivery, reimbursement policy and physician decision-making. OBJECTIVES: The American Society of Dermatopathology, with input from the American Academy of Dermatology and the College of American Pathologists, sought to develop AUC in dermatopathology. METHODS: The RAND/UCLA appropriateness methodology, which combines evidence-based medicine, clinical experience and expert judgment, was used to develop AUC in dermatopathology. RESULTS: With the number of ratings predetermined at 3, AUC were developed for 211 clinical scenarios involving 12 ancillary studies. Consensus was reached for 188 (89%) clinical scenarios, with 93 (44%) considered "usually appropriate," 52 (25%) "rarely appropriate" and 43 (20%) "uncertain appropriateness." LIMITATIONS: The methodology requires a focus on appropriateness without comparison between tests and irrespective of cost. CONCLUSIONS: The ultimate decision of when to order specific test rests with the physician and is one where the expected benefit exceeds the negative consequences. This publication outlines the recommendations of appropriateness-AUC for 12 tests used in dermatopathology. Importantly, these recommendations may change considering new evidence. Results deemed "uncertain appropriateness" and where consensus was not reached may benefit from further research. PMID- 29566274 TI - In silico characterization of broad range proteases produced by Serratia marcescens EGD-HP20. AB - In the present study, Serratia marcescens EGD-HP20 strain was demonstrated to utilize poultry waste comprising of both white non-melanized and dark/brown melanized poultry feathers. The potential of the isolate to hydrolyze diverse keratinous wastes was further corroborated by comparative genomics which indicated the presence of genes for broad substrate specific proteases including metallo-proteases, serine endoprotease, dipeptidase, oligopeptidase, etc. Multiple gene sequence alignments of above genes showed 99-100% sequence identities with that of closely related strains of S. marcescens. The secondary structure, 3D structures and energy models suggested the stable nature of all the observed enzymes. Comparative genomics and hydrolysis of mixed feather waste indicated that the above potential of the isolate was associated with synergistic action of various types of proteases. PMID- 29566275 TI - Acoustic variation of spider monkeys' contact calls (whinnies) is related to distance between vocalizing individuals and immediate caller behavior. AB - Due to several factors such as ecological conditions, group size, and social organization, primates frequently spend time out of visual contact with individuals of their own group. Through the use of long-distance vocalizations, often termed "contact calls," primates are able to maintain contact with out-of sight individuals. Contact calls have been shown to be individually distinct, and reverberation and attenuation provide information about caller distance. It is less clear, however, whether callers actively change the structure of contact calls depending on the distance to the presumed listeners. We studied this question in spider monkeys (Ateles geoffroyi), a species with complex spatial dynamics (fission-fusion society) that produces highly frequency modulated contact calls, denominated "whinnies." We determined the acoustic characteristics of 566 whinnies recorded from 35 free-ranging spider monkeys that belong to a community located in Mexico, and used cluster analyses, discriminant function analyses, and generalized linear mixed models to assess if they varied in relation to the presumed distance to the listener. Whinnies could be grouped into five subtypes. Since the lowest frequency subtype was mainly produced by spider monkeys that exchanged whinnies at longer distances, and lower frequency calls propagate across longer distances, our results suggest that whinnies vary in order to enhance vocal contact between individuals separated by different distances. Our results also revealed that whinnies convey potential information about caller immediate behaviors and corroborated that these calls are individually distinct. Overall, our results suggest that whinny acoustic variation facilitates the maintenance of vocal contact between individuals living in a society with complex spatial dynamics. PMID- 29566276 TI - Angiographic optical coherence tomography imaging of hemangiomas and port wine birthmarks. AB - OBJECTIVES: A current therapeutic challenge of vascular lesions is that they do not always respond effectively to laser treatment. Information on targeted vessels could potentially be used to guide laser treatments. Optical coherence tomography (OCT) is a useful tool for the non-invasive imaging of tissues, including skin hemangiomas and port wine birthmarks. Dynamic OCT is able to rapidly characterize cutaneous blood vessels. The primary goal of this study was to demonstrate the ability of bedside OCT to image (i) overall vessel pattern; (ii) individual vessel morphology, diameter and depth; and (iii) total vessel density as a function of depth in infantile hemangiomas and port wine birthmarks (PWB). MATERIALS AND METHODS: This IRB approved, observational clinical trial was performed among healthy volunteers ages 3 months-73 years old. All patients presented for laser treatment of either infantile hemangiomas or PWB with skin types ranging from Fitzpatrick I-V. OCT imaging of 49 hemangioma and PWB scans were performed pre- and post-treatment. The diameter and depth of the blood vessels making up the vascular lesions were measured. In addition, normal skin was scanned for comparison. Five datasets for infantile hemangiomas and five for PWB that were without motion artifacts were analyzed. RESULTS: Scanned lesions exhibited variable and highly heterogeneous blood vessel patterns with vessel diameters ranging from 20 to 160 MUm, suggesting that the laser treatment with single pulse durations may not be optimal. The largest blood vessel diameter observed (160 MUm) may not be adequately treated by commonly used pulsed dye laser pulse durations. CONCLUSION: OCT allowed rapid, non-invasive characterization of the diameter and depth of blood vessels in individual vascular lesions. Imaged lesions consisted of a heterogeneous population of vessel sizes, morphologies, and depth. Future studies could utilize this information to assist development of individualized treatment protocols in an effort to improve vascular birthmark removal. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc. PMID- 29566277 TI - Stimulation of Fas/FasL-mediated apoptosis by luteolin through enhancement of histone H3 acetylation and c-Jun activation in HL-60 leukemia cells. AB - Luteolin (3',4',5,7-tetrahydroxyflavone), which exists in fruits, vegetables, and medicinal herbs, is used in Chinese traditional medicine for treating various diseases, such as hypertension, inflammatory disorders, and cancer. However, the gene-regulatory role of luteolin in cancer prevention and therapy has not been clarified. Herein, we demonstrated that treatment with luteolin resulted in a significant decrease in the viability of human leukemia cells. In the present study, by evaluating fragmentation of DNA and poly (ADP-ribose) polymerase (PARP), we found that luteolin was able to induce PARP cleavage and nuclear fragmentation as well as an increase in the sub-G0 /G1 fraction. In addition, luteolin also induced Fas and Fas ligand (FasL) expressions and subsequent activation of caspases-8 and -3, which can trigger the extrinsic apoptosis pathway, while knocking down Fas-associated protein with death domain (FADD) prevented luteolin-induced PARP cleavage. Immunoblot and chromatin immunoprecipitation (ChIP) analyses revealed that luteolin increased acetylation of histone H3, which is involved in the upregulation of Fas and FasL. Moreover, both the extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) pathways are involved in luteolin-induced histone H3 acetylation. Finally, luteolin also activated the c-Jun signaling pathway, which contributes to FasL, but not Fas, gene expression and downregulation of c-Jun expression by small interfering RNA transfection which resulted in a significant decrease in luteolin induced PARP cleavage. Thus, our results demonstrate that luteolin induced apoptosis of HL-60 cells, and this was associated with c-Jun activation and histone H3 acetylation-mediated Fas/FasL expressions. PMID- 29566278 TI - Down-regulation of POTEG predicts poor prognosis in esophageal squamous cell carcinoma patients. AB - POTE ankyrin domain family, member G (poteg) belongs to POTE family. The POTE family is composed of many proteins which are very closely related and expressed in prostate, ovary, testis, and placenta. Some POTE paralogs are related with some cancers. Here we showed that down-regulation of POTEG was detected in about 60% primary esophageal squamous cell carcinoma (ESCC) tumor tissues. Clinical association studies determined that POTEG down-regulation was significantly correlated with tumor differentiation, lymph nodes metastasis and TNM staging. Kaplan-Meier analysis determined that POTEG down-regulation was associated with poorer clinical outcomes of ESCC patients (P = 0.026). Functional studies showed that POTEG overexpression could suppress tumor cell growth and metastasis capacity in vitro and in vivo. Molecular analyses revealed that POTEG downregulated CDKs, leading to subsequent inhibition of Rb phosphorylation, and consequently arrested Cell Cycle at G1/S Checkpoint. POTEG overexpression induced apoptosis by activating caspases and PARP, and regulating canonical mitochondrial apoptotic pathways. On the other side, POTEG inhibited epithelial-mesenchymal transition and suppressed tumor cell metastasis. In conclusion, our study reveals a functionally important control mechanism of POTEG in esophageal cancer pathogenesis, suggesting potential use in the ESCC intervention and therapeutic strategies. PMID- 29566279 TI - Recurrent transcriptional loss of the PCDH17 tumor suppressor in laryngeal squamous cell carcinoma is partially mediated by aberrant promoter DNA methylation. AB - Protocadherins are cell-cell adhesion molecules encoded by a large family of genes. Recent reports demonstrate recurrent silencing of protocadherin genes in tumors and provide strong arguments for their tumor supresor functionality. Loss of protocadherins may contribute to cancer development not only by altering cell cell adhesion, that is a hallmark of cancer, but also by enhancing proliferation and epithelial mesenchymal transition of cells via deregulation of the WNT signaling pathway. In this study we have further corroborated our previous findings on the involvement of PCDH17 in laryngeal squamous cell carcinoma (LSCC). We used bisulfite pyrosequencing to analyze a cohort of primary LSCC tumors for alterations in PCDH17 promoter DNA methylation as an alternative gene inactivation mechanism to the homozygous deletions reported earlier. Moreover, we analyzed primary LSCC samples by immunohistochemistry for PCDH17 protein loss. We identified recurrent elevation of PCDH17 promoter DNA methylation in 32/81 (40%) primary tumors (P < 0.001) and therein hypermethylation of 12 (15%) cases in contrast to no tumor controls (n = 24) that were all unmethylated. Importantly, DNA demethylation by decitabine has restored low level PCDH17 expression in LSCC cell lines. In conclusion, we provide a mechanistic explanation of recurrently observed PCDH17 silencing in LSCC by demonstrating the role of promoter methylation in this process. In light of these findings and recent reports showing that PCDH17 methylation is detectable in serum of cancer patients we suggest that testing PCDH17 DNA methylation might serve as a potential biomarker in LSCC. PMID- 29566280 TI - Telescoping Reactions with Trifluorodiazoethane-Derived Aza-Wittig Reagents and Allenyl esters. AB - A telescoping process involving the consecutive addition of four reagents (trifluorodiazoethane, phosphine, allenyl ester, and acetic acid) into a single reactor was developed for the novel functionalization of allenyl esters. First, new phosphazenes derived from trifluorodiazoethane and phosphines were generated and reacted with allenyl esters to give unexpected alpha-iminophosphoranes through the creation of C=P, C=N, and C-H bonds at the alpha-, beta-, and gamma carbon atoms, respectively, of the allenyl esters. The alpha-iminophosphoranes did not react with aldehydes in a classic Wittig reaction, but instead beta enamino esters were obtained. The overall sequence of reactions offered a formal hydrohydrazonation of allenyl esters. The method was extended to other related diazo compounds and applied to the preparation of novel 5-pyrazolone derivatives. Not only is the telescoping process described herein an effective approach for truncating the multistep synthesis, but also each step has been dissected to understand and support the reaction mechanisms. PMID- 29566281 TI - Downregulation of miR-3127-5p promotes epithelial-mesenchymal transition via FZD4 regulation of Wnt/beta-catenin signaling in non-small-cell lung cancer. AB - MiR-3127-5p has been implicated as a tumor-suppressive microRNA (miRNA) in non small-cell lung cancer (NSCLC) and its expression was associated with tumor recurrence and poor prognosis. The aim of this study was to determine whether miR 3127-5p regulates epithelial-mesenchymal transition (EMT) in NSCLC, and to investigate the underlying mechanisms. Using qRT-PCR, we examined the expression levels of miR-3127-5p in a cohort of primary NSCLC specimens with and without distant metastasis. We further performed a series of in vitro and in vivo experiments to investigate the effects and underlying mechanism of miR-3127-5p on EMT, cell migration, invasion, and adhesion in NSCLC. We found that metastatic NSCLC tissues showed markedly downregulated miR-3127-5p expression. Transforming growth factor-beta1 (TGF-beta1) treatment induced EMT in A549 and H1299 cells, and downregulation of miR-3127-5p could result in the similar effect. Mechanically, we demonstrated that frizzled-4 (FZD4) is a target gene and miR 3127-5p exerts its effects by regulating the Wnt/beta-catenin signaling. In addition, the expression levels of FZD4 and miR-3127-5p were also negatively associated in both clinical and xenografted tumors. Overall, these findings suggest that downregulation of miR-3127-5p promotes EMT through activating the Wnt/FZD4/beta-catenin signaling pathway and may represent a therapeutic target for NSCLC metastasis. PMID- 29566282 TI - Oleanolic acid induces osteosarcoma cell apoptosis by inhibition of Notch signaling. AB - Oleanolic acid (OA), a naturally occurring triterpenoid, exhibits potential antitumor activity in several tumor cell lines. Although the inhibition effects of OA on proliferation and survival in human cancers have been confirmed, the potential mechanism underlying OA-induced osteosarcoma cell death has not yet been fully elucidated. Our results in this study showed that OA inhibits proliferation and viability of osteosarcoma cells in a dose-dependent manner. Flow cytometry assays revealed that apoptosis in osteosarcoma cells was significantly induced by OA treatment, while this induction was blocked by Jagged1-mediated activation of Notch signaling. Western blot analysis and a mitochondrial membrane potential assay demonstrated that OA functions through the mitochondrial apoptosis pathway. More importantly, our data revealed that OA treatment interrupted the balance between pro-apoptotic factors and anti apoptotic factors in osteosarcoma cells by inhibition of the Notch signaling pathway. These data suggest that OA induces osteosarcoma cell apoptosis by targeting mitochondria in a Notch signaling-dependent manner. Thus, OA may be a promising drug for adjuvant chemotherapy in osteosarcoma. PMID- 29566283 TI - Aberrant methylation-mediated downregulation of long noncoding RNA C5orf66-AS1 promotes the development of gastric cardia adenocarcinoma. AB - As a long non-coding RNA, C5orf66-AS1 is located at 5q31.1. Downregulation and aberrant hypermethylation of C5orf66-AS1 have been detected in a limited several tumors. However, the biological role and distribution of methylated CpG sites of C5orf66-AS1 in gastric cardia adenocarcinoma (GCA) development and prognosis are poorly clarified. The present study was to investigate the expression status and function of C5orf66-AS1 in GCA, and to detect the distribution of methylated CpG sites within the three CpG islands of the promoter and gene body of C5orf66-AS1, further to clarify its prognostic value in GCA patients. C5orf66-AS1 was significantly downregulated in GCA tissues and cell lines, and the expression level was associated with TNM stage, pathological differentiation, lymph node metastasis, and distant metastasis or recurrence. The expression level of C5orf66 AS1 was significantly increased in cancer cells after treated with 5-Aza-dC. Further methylation analysis demonstrated that the aberrant hypermethylation of the regions around the transcription start site of C5orf66-AS1 was more tumor specific and was associated with its expression. Moreover, Sp1 may upregulate C5orf66-AS1 expression and CpG sites hypermethylation within the binding sites may abrogate Sp1 binding. In addition, C5orf66-AS1 inhibited gastric cancer cell proliferation and invasion, and the dysregulation and hypermethylation of the regions around the transcription start site of C5orf66-AS1 were associated with poorer GCA patients' survival. These findings suggest that aberrant hypermethylation-mediated downregulation of C5orf66-AS1 may play important roles in GCA tumorigenesis and C5orf66-AS1 may serve as a potential prognostic marker in predicting GCA patients' survival. PMID- 29566284 TI - Clinical Effect of C2 Peripheral Nerve Field Stimulation Using Electroacupuncture for Primary Headache. AB - OBJECTIVE: We applied C2 peripheral nerve field stimulation using electroacupuncture (EA-C2-PNfS) for primary headache, and investigated its clinical effectiveness. MATERIALS AND METHODS: Fifty-four primary headache patients (10 men, 44 women) with a mean age of 48.6 +/- 15.0 years underwent EA C2-PNfS for three months. We used questionnaires to assess outcomes; pain intensity (11-point numerical rating scale [NRS]), quality of daily life (Headache Impact Test [HIT-6]), depression (Self-Rating Depression Scale [SDS]). Monthly headache days and acute headache medication days were obtained from diaries. RESULTS: The headache intensity significantly declined after the EA-C2 PNfS with reduction of NRS pain scale; 7.4 +/- 1.9 at baseline, 4.9 +/- 2.9 at three month (p < 0.001). Both HIT-6 and SDS showed significant improvement (p < 0.001). Some patients showed moderate depression in SDS before treatment, that was alleviated in patients with tension-type headache after the EA-C2-PNfS. Monthly headache days significantly decreased from 18.0 +/- 9.0 at one month to 14.0 +/- 10.2 at three months (p < 0.001), accompanied with reduction of the monthly acute headache medication days from 8.0 +/- 6.7 to 6.4 +/- 6.5 (p = 0.003). CONCLUSIONS: EA-C2-PNfS was successfully used for reducing severity and disability in primary headache patients. We conclude that EA-C2-PNfS is a favorable option for medically intractable primary headache as less-invasive neuromodulation. PMID- 29566285 TI - Non-Uniform and Absolute Minimal Sampling for High-Throughput Multidimensional NMR Applications. AB - Many biomolecular NMR applications can benefit from the faster acquisition of multidimensional NMR data with high resolution and their automated analysis and interpretation. In recent years, a number of non-uniform sampling (NUS) approaches have been introduced for the reconstruction of multidimensional NMR spectra, such as compressed sensing, thereby bypassing traditional Fourier transform processing. Such approaches are applicable to both biomacromolecules and small molecules and their complex mixtures and can be combined with homonuclear decoupling (pure shift) and covariance processing. For homonuclear 2D TOCSY experiments, absolute minimal sampling (AMS) permits the drastic shortening of measurement times necessary for high-throughput applications for identification and quantification of components in complex biological mixtures in the field of metabolomics. Such TOCSY spectra can be comprehensively represented by graphic theoretical maximal cliques for the identification of entire spin systems and their subsequent query against NMR databases. Integration of these methods in webservers permits the rapid and reliable identification of mixture components. Recent progress is reviewed in this Minireview. PMID- 29566286 TI - The Breath-Hold Acceleration Index: A New Method to Evaluate Cerebrovascular Reactivity using Transcranial Doppler. AB - BACKGROUND AND PURPOSE: Cerebrovascular reactivity (CR) is an ideal biomarker to detect cerebrovascular damage. CR can be quantified by measuring changes in cerebral blood flow velocity (CBFV) resulting from a CO2 vasodilatory stimulus, often using the breath-holding index (BHI). In this method, transcranial Doppler (TCD) ultrasound is used to measure CBFV changes in the middle cerebral artery (MCA) during a breath-hold maneuver. Despite its convenience, BHI has high variability. Changing body position may contribute to potential variability. It is important to determine if CR differs with body position. The aims of this study were, first, to propose an alternative, more robust index to evaluate CR using a breath-hold maneuver; second, investigate the effect of body position on CR measured with conventional (BHI) and a new proposed index. METHODS: Ten healthy young volunteers held their breath for 30 seconds on a tilt table. CR was calculated at five different angles using two indices: the conventional BHI, and the breath-hold acceleration index (BHAI), a new index obtained by linear regression of the most linear portion of the mean velocity change during the breath-hold maneuver. The regression represents acceleration (change in blood flow velocity per unit of time) sampled at each cardiac cycle. RESULTS: The mean coefficient of variation was 43.7% lower in BHAI in comparison with BHI. Neither index was statistically significant between body positions (P > .05). CONCLUSIONS: BHAI has less variability in comparison with the conventional standard BHI. Additionally, neither index showed statistical significance in CR based on change in body position. PMID- 29566287 TI - Effect of Foetal Bovine Serum on sperm motility, acrosome reaction and spermatic interaction to zona pellucida in alpacas (Vicugna pacos). AB - The use of foetal bovine serum (FBS) in cell culture media is quite common. However, little is known about the effect of FBS on sperm. The severe difficulties in alpaca reproduction demand the search of new methods for in vitro reproductive management. In the present study, we use for the first time FBS as a supplement in the culture medium for sperm in alpaca, and the effect of FBS on motility, acrosome reaction and sperm binding to the zona pellucida in this species was evaluated. A concentration of 10% v/v FBS was used. The sperm motility with FBS at the first hour was 32.8% (vs. control = 30.0%), whereas at the second hour sperm motility with FBS was 30.2% (vs. control = 28.8%). The acrosome reaction reached an average of 44.0% for treatment with FBS (vs. control = 30.1%). The sperm-zona pellucida binding assay showed that the samples incubated with FBS had an average of 2.7 bound sperm (vs. control = 1.7). Only a significant difference was observed for sperm motility at the first hour and for the acrosome reaction. It is concluded that FBS favours the capacitation of sperm in alpaca. PMID- 29566288 TI - Retrograde Placement of High Cervical Electrodes: A Technical Refinement and Case Series. AB - INTRODUCTION: Cervical cord stimulation is used in the treatment of chronic (neuropathic) pain syndromes refractory to conservative treatments. Several authors describe different techniques for the placement of cervical electrodes. Electrodes can be placed retrogade [Correction added on 03 April 2018 after first online publication: the word "plased" has been changed to "placed".]. In this article, we describe a refinement on how to dissect the dorsal meningo-vertebral ligaments to decrease the risk of complications. PATIENTS AND METHODS: Twenty eight patients received a permanent cervical spinal cord stimulator. A C0-C1 retrograde insertion was performed with careful dissection of the meningo vertebral ligaments. Complications were registered during the follow-up (mean 44.6 months [SD = 43, range 1-162 months]). RESULTS: Six complications were observed 93% of the patients reported a significant reduction in pain. CONCLUSIONS: We describe an additional surgical detail for the known procedure for retrograde placement of high cervical plate electrodes. This surgical detail might result in a lower risk of complications. We present a case series of 28 patients to support this hypothesis. PMID- 29566289 TI - Short Interval Intracortical Inhibition Responses to Low-Frequency Repetitive Transcranial Magnetic Stimulation Under Multiple Interstimulus Intervals and Conditioning Intensities. AB - BACKGROUND: The extent to which short interval intracortical inhibition (SICI) responds to low-frequency repetitive transcranial magnetic stimulation (rTMS) remains inconclusive with reports of increased, decreased and unchanged response following modulation. The aim of this study was to systematically investigate if the variability of SICI following rTMS is explained by the interstimulus interval (ISI) and/or the conditioning stimulus intensity (CSI). METHODS: Two experiments with pretesting/posttesting and an rTMS session (1 Hz, 90% RMT, 900 pulses) were done. Experiment I (N = 15): SICI with multiple ISIs (1.0-4.0 msec, 0.2 msec increment). Experiment II (N = 15): SICI with CSIs (50-95% of RMT, 5% increment). In both experiments, the cortical silent period (cSP) was also collected. RESULTS: After low-frequency rTMS, no significant change (p > 0.10) in SICI at any specific ISI or CSI was observed, nor did the optimal ISI or CSI change. However, a significant decrease was observed in SICI responses when assessed under the range of ISIs (p = 0.0001), but not CSIs. cSP inhibition increased significantly (p < 0.0015) for both experiments. CONCLUSIONS: The optimal ISI or CSI did not shift or reveal SICI changes after inhibitory rTMS. However, when the whole curve of SICI responses were evaluated from a wide range of ISIs, a decrease in inhibition was found. The contrast between the results of individual ISI tests and the wide range of ISI assessment may be due to higher intersubject variability of SICI and/or sample size, rendering traditional SICI testing methods ineffective for measuring changes in inhibition. Further, it is possible that rTMS modulates GABAA and GABAB mediated inhibitory processes differently, which would explain the conflicting results for SICI and cSP. PMID- 29566290 TI - Morphology of alpaca (Vicugna pacos) embryos in the first third of pregnancy. AB - The breeding of South American camelids is the main economic activity of the high Andean region of South America and it, is potentially, the most profitable resource in of the Puna environmental conditions of the Puna. The duration of the gestation in alpaca is 339.7 +/- 12 days. The objective of the present work was to macroscopically and microscopically describe the ontogenic development of the splanchnic cavities of the alpaca and to determine the gestational time in which the post-cranial ossification centers are observed in the embryos/fetuses of this species, from day 21 to 107 of gestation. The documentation of normal ontogenic development, which is vacant for this period, is of the utmost importance to understand the consequences of the alterations at the different gestational times, as well as for the estimation of the gestational age in the case of abortions. Forty-seven alpaca specimens of both sexes, at different times of their gestational development, collected during slaughter at local slaughterhouses of the Department of Huancavelica, Peru, were evaluated. Specimens were assigned to seven groups according to their morphological characteristics. The embryogenesis in the alpaca was characterized by a series of changes comparable to those occurring in other mammals with similar gestational periods. Despite these similarities, species differences were found in some organs as stomach, which are observed too in adult individuals.

AB - The first SiIV corrole complexes were synthesized in good yields by treatment of meso-triarylcorroles with tetrachlorosilane in 1,2-dichloroethane at 60 degrees C. The central silicon atom possesses a square-pyramidal coordination geometry with slightly longer Si-N bond lengths as compared with those of known triazacorrole SiIV complexes. The SiIV corrole complexes exhibit sharp and blue shifted absorption spectra and larger fluorescence quantum yields as compared with the corresponding free-base corroles. A MU-oxo dimer of a SiIV corrole was synthesized upon treatment with methanesulfonyl chloride in pyridine at 100 degrees C. This dimer shows a face-to-face structure with a 90 degrees twist in the solid state. Although the dimer exhibits a blue-shifted Soret band, reflecting the face-to-face geometry, it displays a largely red-shifted and broad fluorescence spectrum with a large Stokes shift, suggesting a large structural change in the S1 state. These intriguing optical properties have been comprehensively studied by magnetic circular dichroism (MCD) spectroscopy, femtosecond transient absorption (fs-TA) measurements, and theoretical calculations.

AB - After a brief overview of the biological significance of FAHFAs, the present Minireview highlights the different strategies developed for their chemical syntheses. The term "FAHFAs" has been introduced in 2014 for fatty acyl esters of hydroxyl fatty acids, found in adipocytes, with antidiabetic properties. However, many other natural products contain this type of branched lipids in their structure. This review was then extended to the synthesis of these subunits, even though the length of the lipid chains and the location of the ester linkages are different, since the developed strategies may be applied to the synthesis of "FAHFA". PMID- 29566293 TI - Chemical Insights into the Antioxidant Mechanisms of Alkylseleno and Alkyltelluro Phenols: Periodic Relatives Behaving Differently. AB - The possible antioxidant reaction mechanisms of recently synthesized and tested alkylseleno (telluro) phenols have been explored using density functional theory by considering two solvents physiologically relevant, water and pentylethanoate (PE). In addition, the possible pathway for the antioxidant regeneration with ascorbic acid has been investigated. Results show that selenium and tellurium systems follow different chemical behaviors. In particular, the alkylseleno phenol (ebselenol) antioxidant activity is justified through a sequential proton loss-electron-transfer mechanism in water media, whereas in PE the hydrogen-atom transfer process is favored. In the case of the tellurium derivative, the oxygen transfer mechanism represents the preferential one. Furthermore, electronic properties have been analyzed to rationalize the different reactivity of the selenium- and tellurium-containing systems. To confirm the results, smaller but similar systems were also investigated. The calculated data support the different mechanism (Se vs. Te) proposals. PMID- 29566294 TI - Inflammatory cytokine-mediated induction of serine racemase in atopic dermatitis. AB - Serine racemase (SR) is an enzyme that catalyses the synthesis of d-serine, an endogenous coagonist for N-methyl-D-aspartate (NMDA)-type glutamate receptor in the central nervous system. Our previous study demonstrated that SR was expressed in the epidermis of wild-type (WT) mice but not in SR knockout (KO) mice. In addition, SR immune-reactivity was only found in the granular and cornified layers of the epidermis in WT mice. These findings suggested that SR is involved in the differentiation of epidermal keratinocytes and the formation of the skin barrier. However, its role in skin barrier dysfunction such as atopic dermatitis (AD) remains elusive. AD is a chronic inflammatory disease of skin, and the clinical presentation of AD has been reported to be occasionally associated with psychological factors. Therefore, this study examined the content of d-serine in stratum corneum in AD patients and healthy controls using a tape-stripping method. Skin samples were collected from the cheek and upper arm skin of AD patient's lesion and healthy individuals. The d-serine content was significantly increased in the involved skin of AD in comparison with healthy individuals. An immunohistochemical analysis also revealed an increased SR expression in the epidermis of AD patients. Furthermore, the SR expression in cultured human keratinocytes was significantly increased by the stimulation with tumour necrosis factor -alpha or macrophage migration inhibitory factor. Taken together, these findings suggest that d-serine expressed particularly strongly in AD lesional skin and that the SR expression in the keratinocytes is linked to inflammatory cytokines.

AB - The aim of this study was to examine foetal organs and placental tissue to establish a correlation between the changes in the composition of these structures associated with their maturation and the ultrasonographic characteristics of the images. Twenty-four pregnant ewes were included in the study. Ultrasonography assessments were performed in B-mode, from the ninth gestational week until parturition. The lungs, liver and kidneys of foetuses and placentomes were located in transverse and longitudinal sections to evaluate the echogenicity (hypoechoic, isoechoic, hyperechoic or mixed) and echotexture (homogeneous and heterogeneous) of the tissues of interest. For quantitative evaluation of the ultrasonographic characteristics, it was performed a computerized image analysis using a commercial software (Image ProPlus(r) ). Mean numerical pixel values (NPVs), pixel heterogeneity (standard deviation of NPVs) and minimum and maximum pixel values were measured by selecting five circular regions of interest in each assessed tissue. All evaluated tissues presented significant variations in the NPVs, except for the liver. Pulmonary NPVmean, NPVmin and NPVmax decreased gradually through gestational weeks. The renal parameters gradually decreased with the advancement of the gestational weeks until the 17th week and later stabilized. The placentome NPVmean, NPVmin and NPVmax decreased gradually over the course of weeks. The hepatic tissue did not show echogenicity and echotexture variations and presented medium echogenicity and homogeneous echotexture throughout the experimental period. It was concluded that pixels numerical evaluation of maternal-foetal tissues was applicable and allowed the identification of quantitative ultrasonographic characteristics showing changes in echogenicity related to gestational age.

AB - Molecules comprised of three covalently linked bi-stable switches can exist in states described by a combination of binary numbers, one for each individual switch: ?000?, ?001?, etc. Here we have linked three photo-/thermoswitches together in a rigid macrocyclic structure, one azobenzene (bit no 1) and two dihydroazulenes (DHAs; bits no 2 and 3) and demonstrate how electronic interactions and unfavorable strain in some states can be used to control the speed by which a certain state is reached. More specifically, upon irradiation of state ?000?, the AZB isomerizes from trans to cis and the two DHAs to vinylheptafulvenes (VHFs), generating ?111?. The thermal VHF-to-DHA back reactions from this state also occur stepwise and can be accelerated by photo induced AZB cis-to-trans conversion, proceeding via ?011? to ultimately furnish ?000?. Overall, the accessibility to a specific state of one bit was found to depend on the states of its neighboring bits.

AB - The merging of photoredox and transition-metal catalysis has become one of the most attractive approaches for carbon-carbon bond formation. Such reactions require the use of two organo-transition-metal species, one of which acts as a photosensitizer and the other one as a cross-coupling catalyst. We report herein an exogenous-photosensitizer-free photocatalytic process for the formation of carbon-carbon bonds by direct acceleration of the well-known nickel-catalyzed Negishi cross-coupling that is based on the use of two naturally abundant metals. This finding will open new avenues in cross-coupling chemistry that involve the direct visible-light absorption of organometallic catalytic complexes. PMID- 29566298 TI - Impact of thermo-tactile stimulation on the speed and efficiency of swallowing: a systematic review. AB - BACKGROUND: A delayed or absent swallow reflex is common in dysphagia and can have a significant impact on swallow safety. Recent clinical practice survey data have supported the fact that clinicians continue to use thermo-tactile stimulation (TTS) as a strategy to stimulate key nerve pathways and evoke a swallow reflex for patients with a delayed or absent swallow reflex. AIMS: To conduct a systematic review of the effectiveness of TTS as a compensatory and/or rehabilitative tool. METHODS & PROCEDURES: A search performed on CINAHL, Medline and Speech Bite identified 599 articles. After removing duplicates, the titles and abstracts of 458 articles were assessed for eligibility; 426 articles were deemed to be clearly ineligible and the remaining 32 full-text articles were further screened for inclusion. Ten of these studies were included in this review. MAIN CONTRIBUTION: The results of this review highlight the lack of available evidence in this area and give support to the view that there is only low-level evidence for use of TTS as a compensatory strategy immediately before a swallow. CONCLUSIONS & IMPLICATIONS: There is low-level evidence to support the use of TTS. Current best practice would be to use TTS on a case-by-case basis, following detailed instrumental assessment and evaluation of its efficacy for an individual. PMID- 29566299 TI - Dynamic Nuclear Polarization-Enhanced Biomolecular NMR Spectroscopy at High Magnetic Field with Fast Magic-Angle Spinning. AB - Dynamic nuclear polarization (DNP) is a powerful way to overcome the sensitivity limitation of magic-angle-spinning (MAS) NMR experiments. However, the resolution of the DNP NMR spectra of proteins is compromised by severe line broadening associated with the necessity to perform experiments at cryogenic temperatures and in the presence of paramagnetic radicals. High-quality DNP-enhanced NMR spectra of the Acinetobacter phage 205 (AP205) nucleocapsid can be obtained by combining high magnetic field (800 MHz) and fast MAS (40 kHz). These conditions yield enhanced resolution and long coherence lifetimes allowing the acquisition of resolved 2D correlation spectra and of previously unfeasible scalar-based experiments. This enables the assignment of aromatic resonances of the AP205 coat protein and its packaged RNA, as well as the detection of long-range contacts, which are not observed at room temperature, opening new possibilities for structure determination. PMID- 29566300 TI - Are the effects of drugs to prevent and to treat heart failure always concordant? The statin paradox and its implications for understanding the actions of antidiabetic medications. AB - Most treatments for chronic heart failure are effective both in preventing its onset and reducing its progression. However, statins prevent the development of heart failure, but they do not decrease morbidity and mortality in those with established heart failure. This apparent discordance cannot be explained by an effect to prevent interval myocardial infarctions. Instead, it seems that the disease that statins were preventing in trials of patients with a metabolic disorder was different from the disease that they were treating in trials of chronic heart failure. The most common phenotype of heart failure in patients with obesity and diabetes is heart failure with a preserved ejection fraction (HFpEF). In this disorder, the anti-inflammatory effects of statins might ameliorate myocardial fibrosis and cardiac filling abnormalities, but these actions may have little relevance to patients with heart failure and a reduced ejection fraction (HFrEF), whose primary derangement is cardiomyocyte loss and stretch. These distinctions may explain why statins were ineffective in trials that focused on HFrEF, but have been reported to produce favourable effects in observational studies of HFpEF. Similarly, selective cytokine antagonists were ineffective in HFrEF, but have been associated with benefits in HFpEF. These observations may have important implications for our understanding of the effects of antihyperglycaemic medications. Glucagon-like peptide-1 receptor agonists have had neutral effects on heart failure events in people at risk for HFpEF, but have exerted deleterious actions in HFrEF. Similarly, sodium-glucose co-transporter 2 inhibitors, which exert anti-inflammatory effects and reduce heart failure events in patients who are prone to HFpEF, may not be effective in HFrEF. The distinctions between HFrEF and HFpEF may explain why the effects of drugs on heart failure events in diabetes trials may not be relevant to their use in patients with systolic dysfunction. PMID- 29566301 TI - Graphene: A Cathode Material of Choice for Aluminum-Ion Batteries. AB - The pairing of an aluminum anode with a cathode of high energy and power density determines the future of aluminum-ion battery technology. The question is-"Is there any suitable cathode material which is capable of storing sufficiently large amount of trivalent aluminum-ions at relatively higher operating potential?". Graphene emerges to be a fitting answer. Graphene emerged in the research arena of aluminum-ion battery merely three years ago. However, research progress in this front has since been tremendous. Outperforming all other known cathode materials, several remarkable breakthroughs have been made with graphene, in offering extraordinary energy density, power density, cycle life, thermal stability, safety and flexibility. The future of the Al-graphene couple is indeed bright. This Minireview highlights the electrochemical performances, advantages and challenges of using graphene as the cathode in aluminum-ion batteries in conjugation with chloroaluminate based electrolytes. Additionally, the complex mechanism of charge storage in graphene is also elaborated. PMID- 29566302 TI - Sight-threatening complications of cosmetic iris implants.

AB - Over the last few years, a shift from curative towards preventive medicine occurred in the livestock sector. This led to an increased importance of biosecurity to better control infectious diseases by preventing their introduction and/or reducing their spread. Farmers are the main responsible actors of biosecurity measures (BSM). Existing studies report a low implementation level of BSM by the cattle farmers. Barriers such as cost, usefulness, importance, workload and lack of knowledge were investigated but the decision-making process of farmers related to a given BSM is not yet clarified. The objectives of this study were to (i) assess the level of implementation of BSM in cattle farms, (ii) assess the correlation between the importance that farmers give to a BSM and its effective implementation and (iii) identify the main reasons of non-implementation. A randomized survey was implemented in Belgium from December 2016 up to April 2017 with face-to-face interviews conducted in 100 Belgian farms. A descriptive analysis of data was performed using Microsoft Excel(r) and Stata14(r) . Chi-square and Spearman's rank correlation tests, respectively, allowed comparing implementation levels in dairy herds vs. beef herds and investigating the correlation between the importance that farmers give to a BSM and its implementation level. Biosecurity measures were poorly implemented to prevent disease introduction through direct contact and almost not to avoid indirect transmission. Some measures showed a significant difference in terms of implementation level between beef and dairy herds. A positive correlation was highlighted between the importance that farmers give to a BSM and its actual effective implementation. Perceived lack of efficiency, feasibility and usefulness are the reasons most often mentioned for non implementation. Other factors potentially influencing the decision-making process should be further investigated and clarified. Evidence-based studies would be useful to convince the farmers of the need of implementing BSM. PMID- 29566304 TI - Oligodendrocyte gene expression is reduced by and influences effects of chronic social stress in mice. AB - Oligodendrocyte gene expression is downregulated in stress-related neuropsychiatric disorders, including depression. In mice, chronic social stress (CSS) leads to depression-relevant changes in brain and emotional behavior, and the present study shows the involvement of oligodendrocytes in this model. In C57BL/6 (BL/6) mice, RNA-sequencing (RNA-Seq) was conducted with prefrontal cortex, amygdala and hippocampus from CSS and controls; a gene enrichment database for neurons, astrocytes and oligodendrocytes was used to identify cell origin of deregulated genes, and cell deconvolution was applied. To assess the potential causal contribution of reduced oligodendrocyte gene expression to CSS effects, mice heterozygous for the oligodendrocyte gene cyclic nucleotide phosphodiesterase (Cnp1) on a BL/6 background were studied; a 2 genotype (wildtype, Cnp1+/- ) * 2 environment (control, CSS) design was used to investigate effects on emotional behavior and amygdala microglia. In BL/6 mice, in prefrontal cortex and amygdala tissue comprising gray and white matter, CSS downregulated expression of multiple oligodendroycte genes encoding myelin and myelin-axon-integrity proteins, and cell deconvolution identified a lower proportion of oligodendrocytes in amygdala. Quantification of oligodendrocyte proteins in amygdala gray matter did not yield evidence for reduced translation, suggesting that CSS impacts primarily on white matter oligodendrocytes or the myelin transcriptome. In Cnp1 mice, social interaction was reduced by CSS in Cnp1+/- mice specifically; using ionized calcium-binding adaptor molecule 1 (IBA1) expression, microglia activity was increased additively by Cnp1+/- and CSS in amygdala gray and white matter. This study provides back-translational evidence that oligodendrocyte changes are relevant to the pathophysiology and potentially the treatment of stress-related neuropsychiatric disorders. PMID- 29566305 TI - Ginsenoside Rg3 stereoisomers differentially inhibit vascular smooth muscle cell proliferation and migration in diabetic atherosclerosis. AB - Ginsenoside 20(R/S)-Rg3, as a natural peroxisome proliferator-activated receptor gamma (PPARgamma) ligand, has been reported to exhibit differential biological effects. It is of great interest to understand the stereochemical selectivity of 20(R/S)-Rg3 and explore whether differential PPARgamma activation by Rg3 stereoisomers, if it exists, could lead to differential physiological outcome and therapeutic effects in diabetic atherosclerosis. Here, we investigated the binding modes of 20(R/S)-Rg3 stereoisomers in the PPARgamma ligand-binding domain (PPARgamma-LBD) using molecular modelling and their effects on smooth muscle cell proliferation and migration induced by advanced glycation end products (AGEs). The results revealed that 20(S)-Rg3 exhibited stronger antiproliferative and antimigratory effects due to stronger PPARgamma activation. To validate the in vitro results, we used a mice model with diabetic atherosclerosis and obtained that 20(S)-Rg3 markedly reduced the plaque size secondary to reducing the proliferation and migration of VSMCs, while the plaques were more stable due to improvements in other plaque compositions. The results shed light on the structural difference between Rg3 stereoisomers that can lead to significant differential physiological outcome, and the (S)-isomer seems to be the more potent isomer to be developed as a promising drug for diabetic atherosclerosis. PMID- 29566306 TI - Bovine anaplasmosis and tick-borne pathogens in cattle of the Galapagos Islands. AB - A cross-sectional study was conducted to determine the species of Anaplasma spp. and estimate its prevalence in cattle of the three main cattle-producing Galapagos Islands (Santa Cruz, San Cristobal and Isabela) using indirect PCR assays, genetic sequencing and ELISA. Ticks were also collected from cattle and scanned for 47 tick-borne pathogens in a 48 * 48 real-time PCR chip. A mixed effects logistic regression was performed to identify potential risk factors explaining Anaplasma infection in cattle. A. phagocytophilum was not detected in any of the tested animals. Genetic sequencing allowed detection of A. platys-like strains in 11 (36.7%) of the 30 Anaplasma spp.-positive samples analysed. A. marginale was widespread in the three islands with a global between-herd prevalence of 100% [89; 100]95% CI and a median within-herd prevalence of 93%. A significant association was found between A. marginale infection and age with higher odds of being positive for adults (OR = 3.3 [1.2; 9.9]95% Bootstrap CI ). All collected ticks were identified as Rhipicephalus microplus. A. marginale, Babesia bigemina, Borrelia theileri and Francisella-like endosymbiont were detected in tick pools. These results show that the Galapagos Islands are endemic for A. marginale. PMID- 29566307 TI - Enhancing amplification of late-outgrowth endothelial cells by bilobalide. AB - Transfusion of autologous late-outgrowth endothelial cells (OECs) is a promising treatment for restenosis after revascularization. Preparing cells by in vitro amplification is a key step to implement the therapy. This study aimed to demonstrate that bilobalide, a terpenoid, enhances the OEC amplification. Human-, rabbit- and rat OECs and a mouse femoral artery injury model were used. Expanding OECs used endothelial growth medium-2 as the standard culture medium while exploring the mechanisms used endothelial basal medium-2. Proliferation assay used MTT method and BrdU method. Migration assay used the modified Boyden chamber. Intracellular nitric oxide, superoxide anion, hydroxyl radical/peroxynitrite and H2 O2 were quantified with DAF-FM DA, dihydroethidium, hydroxyphenyl fluorescein and a H2 O2 assay kit, respectively. Activated ERK1/2 and eNOS were tested with the Western blot. Bilobalide concentration-dependently enhanced OEC number increase in vitro. Transfusion of bilobalide-based human OECs into femoral injured athymia nude mouse reduced the intimal hyperplasia. Bilobalide promoted OEC proliferation and migration and increased the intracellular nitric oxide level. L-NAME, a NOS inhibitor, inhibits but not abolishes OEC proliferation, migration and ERK1/2 activation. Bilobalide concentration-dependently enhanced the eNOS Ser-1177 phosphorylation and Thr-495 dephosphorylation in activated OECs. Bilobalide alleviates the increase in hydroxyl radical/peroxynitrite, superoxide anion and H2 O2 in proliferating OECs. In conclusion, nitric oxide plays a partial role in OEC proliferation and migration; bilobalide increases OEC nitric oxide production and decreases nitric oxide depletion, promoting the OEC number increase; Bilobalide-based OECs are active in vivo. The findings may simplify the preparation of OECs, facilitating the implementation of the autologous-OECs-transfusion therapy. PMID- 29566308 TI - Functional mesoporous silica nanoparticles for bio-imaging applications. AB - Biomedical investigations using mesoporous silica nanoparticles (MSNs) have received significant attention because of their unique properties including controllable mesoporous structure, high specific surface area, large pore volume, and tunable particle size. These unique features make MSNs suitable for simultaneous diagnosis and therapy with unique advantages to encapsulate and load a variety of therapeutic agents, deliver these agents to the desired location, and release the drugs in a controlled manner. Among various clinical areas, nanomaterials-based bio-imaging techniques have advanced rapidly with the development of diverse functional nanoparticles. Due to the unique features of MSNs, an imaging agent supported by MSNs can be a promising system for developing targeted bio-imaging contrast agents with high structural stability and enhanced functionality that enable imaging of various modalities. Here, we review the recent achievements on the development of functional MSNs for bio-imaging applications, including optical imaging, magnetic resonance imaging (MRI), positron emission tomography (PET), computed tomography (CT), ultrasound imaging, and multimodal imaging for early diagnosis. With further improvement in noninvasive bio-imaging techniques, the MSN-supported imaging agent systems are expected to contribute to clinical applications in the future.

PMID- 29566309 TI - Alpha B-crystallin promotes the invasion and metastasis of gastric cancer via NF kappaB-induced epithelial-mesenchymal transition. AB - Alpha B-crystallin (CRYAB) is overexpressed in a variety of cancers. However, little is known about its specific function and regulatory mechanism in gastric cancer. Here, we first explore the role of CRYAB in gastric cancer progression and metastasis. The expression of CRYAB was determined by western blot and immunohistochemistry in gastric cancer tissues. Besides, methods including stably transfected against CRYAB into gastric cancer cells, western blot, migration and invasion assays in vitro and metastasis assay in vivo were also conducted. The expression of CRYAB is up-regulated in gastric cancer tissues compared with matched normal tissues. High expression level of CRYAB is closely correlated with cancer metastasis and shorter survival time in patients with gastric cancer. Additionally, CRYAB silencing significantly suppresses epithelial-mesenchymal transition (EMT), migration and invasion of gastric cancer cells in vitro and in vivo, whereas CRYAB overexpression dramatically reverses these events. Mechanically, CRYAB facilitates gastric cancer cells invasion and metastasis via nuclear factor-kappa-gene binding (NF-kappaB)-regulated EMT. These findings suggest that CRYAB expression predicts a poor prognosis in patients with gastric cancer. Besides, CRYAB contributes to gastric cancer cells migration and invasion via EMT, mediated by the NF-kappaB signalling pathway, thus possibly providing a novel therapeutic target for gastric cancer. PMID- 29566310 TI - DC-CIK cells derived from ovarian cancer patient menstrual blood activate the TNFR1-ASK1-AIP1 pathway to kill autologous ovarian cancer stem cells. AB - Ovarian cancer stem cells (OCSCs) are highly carcinogenic and have very strong resistance to traditional chemotherapeutic drugs; therefore, they are an important factor in ovarian cancer metastasis and recurrence. It has been reported that dendritic cell (DC)-cytokine-induced killer (CIK) cells have significant killing effects on all cancer cells across many systems including the blood, digestive, respiratory, urinary and reproductive systems. However, whether DC-CIK cells can selectively kill OCSCs is currently unclear. In this study, we collected ovarian cancer patient menstrual blood (OCPMB) samples to acquire mononuclear cells and isolated DC-CIK cells in vitro. In addition, autologous CD44+/CD133+ OCSCs were isolated and used as target cells. The experimental results showed that when DC-CIK cells and OCSCs were mixed and cultured in vitro at ratios of 5:1, 10:1 and 50:1, the DC-CIK cells killed significant amounts of OCSCs, inhibited their invasion in vitro and promoted their apoptosis. The qPCR and Western blot results showed that DC-CIK cells stimulated high expression levels and phosphorylation of TNFR1, ASK1, AIP1 and JNK in OCSCs through the release of TNF-alpha. After the endogenous TNFR1 gene was knocked out in OCSCs using the CRISPR/Cas9 technology, the killing function of DC-CIK cells on target OCSCs was significantly attenuated. The results of the analyses of clinical samples suggested that the TNFR1 expression level was negatively correlated with ovarian cancer stage and prognosis. Therefore, we innovatively confirmed that DC CIK cells derived from OCPMB could secret TNF-alpha to activate the expression of the TNFR1-ASK1-AIP1-JNK pathway in OCSCs and kill autologous OCSCs. PMID- 29566311 TI - IL-7 suppresses macrophage autophagy and promotes liver pathology in Schistosoma japonicum-infected mice. AB - In schistosomiasis japonica and mansoni, parasite eggs trapped in host liver elicit severe liver granulomatous inflammation that subsequently leads to periportal fibrosis, portal hypertension, haemorrhage or even death. Macrophages are critical for granuloma formation and the development of liver fibrosis during schistosomiasis. However, whether the aberrant regulation of macrophage autophagy has an effect on the development of liver immunopathology in schistosomiasis remains to be elucidated. In this study, we showed that Schistosoma japonicum (S. japonicum) egg antigen (SEA)-triggered macrophage autophagy limited the development of pathology in host liver. However, engagement of IL-7 receptor (IL 7R/CD127) on macrophages by S. japonicum infection-induced IL-7 significantly suppressed SEA-triggered macrophage autophagy, which led to an enhanced liver pathology. In addition, anti-IL-7 neutralizing antibody or anti-CD127 blocking antibody treatment increased macrophage autophagy and suppressed liver pathology. Finally, we demonstrated that IL-7 protects macrophage against SEA-induced autophagy through activation of AMP-activated protein kinase (AMPK). Our study reveals a novel role for IL-7 in macrophage autophagy and identifies AMPK as a novel downstream mediator of IL-7-IL-7R signalling and suggests that manipulation of macrophage autophagy by targeting IL-7-IL-7R signalling may have the potential to lead to improved treatment options for liver pathogenesis in schistosomiasis. PMID- 29566312 TI - Outcome assessment for Brachial Plexus birth injury. Results from the iPluto world-wide consensus survey. AB - There is no consensus regarding strategies to optimally treat children with a brachial plexus birth injury (BPBI). Comparison of outcome data presented by different centers is impossible due to the use of (1) many different outcome measures to evaluate results; (2) different follow-up periods after interventions; and (3) different patient ages at the time of assessment. The goal of iPluto (international PLexus oUtcome sTudy grOup) was to define a standardized dataset which should be minimally collected to evaluate upper limb function in children with BPBI. This dataset must enable comparison of the treatment results of different centers if prospectively used. Three rounds of internet surveys were used to reach consensus on the dataset. A Delphi-derived technique was applied using a nine point Likert scale. Consensus was defined as having attained a rating of 7/8/9 by > = 75% of the participants. A total of 59 participants from five continents participated in the Second and Third Rounds of the survey. Consensus was reached regarding four elements: (1) evaluation should take place at the age of 1/3/5/7 years; range of motion in degrees should be measured for (2) passive joint movement; (3) active range of motion; and (4) the Mallet score should be determined. Consensus on how to asses and report outcome for BPBI was only reached on motor items from the "Body Function and Structure" domain. Consensus regarding additional ICF domains to obtain a more elaborate set of outcome items, should be addressed in future research. (c) 2018 The Authors.

PMID- 29566313 TI - Spinal Cord Stimulation for the Treatment of Failed Neck Surgery Syndrome: Outcome of a Prospective Case Series. AB - OBJECTIVES: Spinal cord stimulation (SCS) is an accepted, cost-effective treatment option for a variety of chronic pain syndromes, including failed back surgery syndrome (FBSS). The application of SCS in the cervical spine, particularly for pain after cervical spine surgery, has been drawn into question in recent years by payers due to a purported lack of clinical evidence. To challenge this claim, we analyzed data from a prospective registry to support the use of SCS in the cervical spine for pain after spine surgery. MATERIALS AND METHODS: Data from the EMPOWER and PAIN registries were analyzed on patients diagnosed with pain after neck surgery (C-FBSS) for the following outcomes: patient reported percent pain relief (PRPR), pain disability index (PDI), quality of life (QoL), and satisfaction at 3-, 6-, and 12-month post-implantation. Statistical analysis was provided for all measures. RESULTS: Fifteen patients with C-FBSS were successfully implanted with SCS leads in the cervical spine. PRPR was 65.2%, 62.4%, and 71.9% at 3-, 6-, and 12-month post-implantation, respectively. PDI scores were significantly reduced from baseline (51.21-23.70 at 12 months, p = 0.001). At one-year post-implantation, the average overall QoL was reported to be improved/greatly improved and patient satisfaction was rated satisfied/greatly satisfied. CONCLUSIONS: For many, the application of SCS in the neck for pain after surgery is based on the obvious similarities to FBSS or anecdotal experience rather than published data. The data contained herein suggest SCS for C-FBSS is an effective therapy that improves QoL and patient satisfaction, as well as decreasing pain and PDI. The use of successful application of neurostimulation as a therapy has largely been predicated on the principles of patient selection, implantation technique, and stimulation parameters. As such, SCS would appear to be an appropriate and valid treatment for C-FBSS that requires further study and investigation to make additional recommendations.

AB - More than 32% of maternal mortality reported in Ethiopia is due to unsafe abortions. Women's knowledge of abortion legislation is a key determinant of the utilization of safe abortion services. The objective of this study was to determine knowledge of abortion legislation and associated factors among female students of Dabat Preparatory School. A quantitative school-based cross-sectional study was conducted from May 25-June 7/2014. Data were collected from 234 randomly selected female students using structured and pre-tested questionnaire. Majority of the participants, 147 (62.8%) know that the law in Ethiopia allows safe and legal abortion under certain circumstances. Ninety-seven (41.5%) of them have poor knowledge towards the legality of induced abortion in Ethiopia. Higher family income (OR=2.63, 95% CI=1.22-5.63), knowing the place where safely induced abortion can be performed (2.51, 95%CI=1.31-4.81) and current use of contraceptive (OR=2.3, 95% CI, 1.1-4.81) are significantly associated with knowledge of the abortion legislation. Student's knowledge of the legal status of abortion is still low. School-based health education about abortion legislation and where it can be safely performed is essential.

According to the Ghana Demographic and Health Surveys, about 22% of Ghanaian women of reproductive age currently use contraception. We analyzed contraceptive use among a representative sample of women in Accra, Ghana, to better understand contraceptive use patterns. We used data from two cross sectional surveys of a representative cohort of women in Accra. In 2003, 28.9% of sexually active women used a contraceptive method. In 2008, 31.5% of sexually active women used a contraceptive method. Additionally, we observed high rates of discontinuation-from 64.1% among those using longer-acting methods to 82.1% among those using traditional methods-between years. Further research on women's contraceptive decision-making is needed to explain these patterns and to ensure that family planning interventions meet the needs of women in Ghana.

AB - Growing evidence shows that the experience of sexual coercion is fairly prevalent among young people and is associated with risky sexual behavior thereafter. This study compared patterns and correlates of sexual coercion among young people in northern and southern Nigeria. This cross-sectional comparative study investigated sexual coercion among 12,626 young women aged between 15 and 24 years. Respondents were all selected from all six geopolitical zones in Nigeria and divided into three northern and southern zones respectively. Relevant information was extracted from a nationally representative sample of young women from the NDHS survey data and analyzed using SPSS for windows Version 16. About 54% of respondents in spousal relationship in the northern part of Nigeria reported occasionally being physically forced to sex when not wanted compared to about 46% southern Nigeria. About, 74% of respondents in the south had been sexually coerced or forced by persons other than partner compared to 26% in the north. Majority of perpetuators were strangers (22.2%), and friends or acquaintances (20.3%). This study indicates that spousal sexual coercion was more common in northern Nigeria while sexual coercion occurring in non-spousal relationships was more prevalent in southern Nigeria.

AB - This study aimed to determine the frequency and the nature of maternal near miss (NM) events in a population of women attending a tertiary level maternity hospital in Tunisia and to evaluate the care level of this institution according to indicators proposed by the World Health Organization (WHO). We opted for a retrospective medical chart review of cases of NM and maternal mortality that occurred in the year 2010 at the Farhat Hached Maternity University Hospital. NM cases were defined based on the WHO criteria 2009. There were 9957 deliveries, 58 NM events and one case of maternal death. Haemorrhagic (74.1%) and hypertensive disorders (20.7%) were the leading causes of NM. The study showed a low Maternal NM Ratio of 5.86/1000 live births, a relatively low mortality index of 1.7 % and Severe Maternal Outcome Ratio of 5.96/1000 live births. This was the first study to document NM in a Tunisian public maternity. The WHO approach allowed a systematic monitoring of quality of maternal health care. There is a low frequency of maternal morbidity and mortality at the level of this facility. But, more efforts are still needed to document NM events in other types of care facilities in Tunisia.

AB - We evaluated the safety and acceptability of the ShangRing device for male circumcision during routine clinical service delivery in Namitete, Malawi. We conducted a prospective observational study enrolling 500 HIV-negative men ages 18 to 49 years at St. Gabriel's Hospital. Participants returned for two follow-up visits: the removal visit (day 7 after placement) and the healing check visit (day 42 after placement). We assessed pain, adverse events (AEs), acceptability, and healing. 500 men were screened; 498 were circumcised using the ShangRing and comprised the analysis population. Seven participants (1.4%) experienced moderate AEs related to circumcision. 93% were judged to be completely healed at or before the day 42 visit; 6% were judged to be healed later than the day 42 visit; 5 participants (1.0%) were lost to follow-up. 98% of men stated they were very satisfied with the appearance of their circumcised penis, and 99.6% would recommend ShangRing circumcision to family/friends. Adult male circumcision using the ShangRing was safe with a low AE rate at this service delivery site. Acceptability factors were also favorable. Addition of the ShangRing device could be beneficial to achieving the goals of the circumcision program in Malawi. PMID- 29566321 TI - Gender-Based Violence following Social Media Acquaintance in Nigeria. AB - In Nigeria, the growth in mobile phone use has provided the opportunity for increased access to the internet, and through this, the social media. The social media in turn offers tremendous communication benefits but also results in some undesirable consequences. One of such is the experience of Gender-Based Violence (GBV). Internet searches using Google Search and Google Scholar in addition to information available to the authors from news media is reported in this study. Five cases were selected for reporting. All cases selected had first contact with their perpetrator(s) on Facebook. The perpetrators were usually men, older than the victims (24-34 years for perpetrators compared with 17-25 years for the victims). The victims experienced physical, psychological, sexual and economic violence from their aggressors. One case resulted in the death of the victim, while two required hospitalization following severe trauma. Three of the victims were raped, while rape was attempted for the other two cases. GBV associated with acquaintances made on social media channels is emerging as a new social problem in Nigeria. Interventions to educate female social media users about this potential danger are urgently necessary. PMID- 29566319 TI - A Qualitative Study of Substance use during Pregnancy: Implications for Reproductive Healthcare in Western Kenya. AB - Women who use alcohol and drugs are often in their childbearing years, creating a need for integrated substance abuse and reproductive health services. However, our understanding of the social context and drivers of substance use during pregnancy, particularly in developing countries, is limited and largely unaddressed in clinical care. Our qualitative research explored the reproductive health of women of childbearing age who inject drugs and its implications for healthcare in Kisumu, Kenya. We used in-depth, semi-structured qualitative interviews with 17 women who inject drugs to explore reproductive health topics including knowledge, practices, and clinical interactions related to substance use during pregnancy. All but one woman had a prior pregnancy and two were pregnant during our study. Alcohol and drug use was prevalent throughout pregnancy, often described as a coping mechanism for stress. Women received mixed advice from family and social contacts regarding alcohol use during pregnancy, leading to differing perceptions of its health effects. Healthcare providers infrequently screened women for alcohol or drug use. Our analysis highlights the need for culturally appropriate alcohol and drug screening and counseling to be included in integrated reproductive health services in western Kenya.

A Randomized Trial (CANHIV Study). AB - A two-arm, open label, randomized study, evaluated the test characteristics of visual inspection of cervix with Acetic acid(VIA) and Lugol"s Iodine(VILI) in detecting cytology diagnosed squamous intraepithelial lesion(SIL) in 1160 women of known HIV status in southwestern Nigerian. Using SIL as reference standard and the HIV status masked, VIA and VILI had similar test characteristics except for the positive predictive value in which VIA value of 91.5% was significantly higher than 77.7% for VILI ( p=0.01). Among HIV positive women, VILI performed poorly across all the 4 test characteristics compared to VIA. Among severely immuno-compromised HIV positive participants VILI performance was consistently below 80% across all test characteristics (sensitivity-70.0%; specificity-66.9%; positive predictive value-46.7%; negative predictive value(NPV)-50.0%) compared to VIA (Senstivity-71.3%; specificity-88.2%; positive predictive value-83.3%; negative predictive value -88.2). Our study shows that VILI is insufficiently sensitive and specific in the presence of HIV infection especially in those with severe immunosuppression. Based on VIA"s acceptable sensitivity and NPV in all situations, it is recommended for cervical cancer screening in HIV positive women and in settings of high HIV burden. PMID- 29566323 TI - Exploring the Barriers to Breast and Cervical Cancer Screening in Nigeria: A Narrative Review. AB - Breast and cervical cancers are the most common causes of female cancer-related mortality in Nigeria. Early detection and treatment significantly decreases cancer mortality rates. Various factors influence uptake of cancer screening. Cancer awareness, availability of screening, and treatment facilities alone have not been completely successful in improving cancer health behaviour. This review aims to identify and summarise the barriers to breast and cervical cancer screening uptake in Nigeria. Various databases such as PubMed, Psych Info, Google Scholar and EMBASE were extensively searched for existing literature on factors influencing breast and cervical cancer screening in Nigeria. Studies retrieved explored the major socioeconomic factors affecting women's knowledge, perception, and attitude. Embarrassment, low perception of cancer risk, and physician gender preference are some of the most common factors that discouraged women from cancer screening. Lack of spouse permission and support; belief that cancer is a death wish, and societal discrimination are the common sociocultural barriers to screening. These factors vary across different regions in Nigeria. Therefore, policy makers should make deliberate effort to develop cancer management strategies that are tailored to the sociocultural and religious needs in a target population. This approach is anticipated to improve uptake and ensure sustainability of cancer management. PMID- 29566324 TI - Prevalence and Patterns of Sexual Activity during Pregnancy in Kano, Northern Nigeria. AB - Very little has been documented on sexual activity during pregnancy in northern Nigeria. We examined prevalence and factors associated with vaginal intercourse during pregnancy in Kano, Nigeria. A cross section of 336 pregnant women attending antenatal care at Aminu Kano Teaching Hospital was interviewed using pre-tested structured questionnaire. Nearly all respondents (96.4%; n=324) reported vaginal intercourse during the index pregnancy. By trimester, 88.4%, 90.7% and 97.4% women had coitus during the first, second and third trimesters respectively, (P>0.05). Relative to pre-pregnancy behavior, 55.4%, 16.3% and 28.3% women reported decreased, increased and unchanged coital frequency, respectively. Ninety six (29.6%) of the sexually active women reported having problems. These included vaginal soreness/pain, abdominal discomfort, bleeding, rupture of the membranes, urinary incontinence and vaginal dryness and itching. History of previous miscarriages and higher pre-pregnancy coital frequency were significantly associated with sexual activity during pregnancy (P <0.05). Vaginal intercourse is nearly universal among pregnant women attending this center with little variation between the trimesters. Health providers should counsel couples on safe coital activity during pregnancy and clear any misconceptions. PMID- 29566325 TI - DFT-SAPT Intermolecular Interaction Energies Employing Exact-Exchange Kohn-Sham Response Methods. AB - Intermolecular interaction energies have been calculated by symmetry-adapted perturbation theory based on density functional theory monomer properties (DFT SAPT) employing response functions from time-dependent exact-exchange (TDEXX) kernels. Combined with a new asymptotic correction scheme for the exchange correlation (xc) potentials of the monomers, which is similar in its performance to standard asymptotic correction methods, it is shown that this DFT-SAPT[TDEXX] method delivers highly accurate intermolecular interaction energies for the S22, S66, and IonHB benchmark databases by Hobza et al. A corresponding DFT-SAPT approach employing the adiabatic TDEXX kernel in the response calculations has also been tested. This DFT-SAPT[ATDEXX] method performs almost as well as DFT SAPT[TDEXX] for dispersion-dominated dimer systems but less accurately for hydrogen-bonded dimers. Compared to this, DFT-SAPT[TDEXX] yields a balanced description of the interaction energies for various interaction-type motifs, similar to the standard DFT-SAPT method that utilizes the ALDA xc kernel to compute the response functions.

AB - Despite the excellent optical features of fully inorganic cesium lead halide (CsPbX3) perovskite quantum dots (PeQDs), their unstable nature has limited their use in various optoelectronic devices. To mitigate the instability issues of PeQDs, we demonstrate the roles of dual-silicon nitride and silicon oxide ligands of the polysilazane (PSZ) inorganic polymer to passivate the surface defects and form a barrier layer coated onto green CsPbBr3 QDs to maintain the high photoluminescence quantum yield (PLQY) and improve the environmental stability. The mixed SiN x/SiN xO y/SiO y passivated and encapsulated CsPbBr3/PSZ core/shell composite can be prepared by a simple hydrolysis reaction involving the addition of adding PSZ as a precursor and a slight amount of water into a colloidal CsPbBr3 QD solution. The degree of the moisture-induced hydrolysis reaction of PSZ can affect the compositional ratio of SiN x, SiN xO y, and SiO y liganded to the surfaces of the CsPbBr3 QDs to optimize the PLQY and the stability of CsPbBr3/PSZ core/shell composite, which shows a high PLQY (~81.7%) with improved thermal, photo, air, and humidity stability as well under coarse conditions where the performance of CsPbBr3 QDs typically deteriorate. To evaluate the suitability of the application of the CsPbBr3/PSZ powder to down-converted white-light emitting diodes (DC-WLEDs) as the backlight of a liquid crystal display (LCD), we fabricated an on-package type of tricolor-WLED by mixing the as-synthesized green CsPbBr3/PSZ composite powder with red K2SiF6:Mn4+ phosphor powder and a poly(methyl methacrylate)-encapsulating binder and coating this mixed paste onto a cup-type blue LED. The fabricated WLED show high luminous efficacy of 138.6 lm/W (EQE = 51.4%) and a wide color gamut of 128% and 111% without and with color filters, respectively, at a correlated color temperature of 6762 K. PMID- 29566327 TI - Synthesis of Iron Oxide Nanoclusters by Thermal Decomposition. AB - Herein, we report a novel one-step solvothermal synthesis of magnetite nanoclusters (MNCs). In this report, we discuss the synthesis, structure, and properties of MNCs and contrast enhancement in T2-weighted MR images using magnetite nanoclusters. The effect of different organic acids, used as surfactants, on the size and shape of MNCs was investigated. The structure and properties of samples were determined by magnetic measurements, TGA, TEM, HRTEM, XRD, FTIR, and MRI. Magnetic measurements show that obtained MNCs have relatively high saturation magnetization values (65.1-81.5 emu/g) and dependence of the coercive force on the average size of MNCs was established. MNCs were transferred into an aqueous medium by Pluronic F-127, and T2-relaxivity values were determined. T2-Weighted MR phantom images clearly demonstrated that such magnetite nanoclusters can be used as contrast agents for MRI.

AB - Sialic acid present on the cell surface is recognized by hemagglutinin (HA) on the influenza virus in the first step of infection. Therefore, a compound that can efficiently interfere with the interaction between sialic acid and HA might inhibit infection and allow detection of the influenza virus. We focused on the spatial arrangement of sialic acid binding sites on HA and developed 2,3 sialyllactose (2,3-SL)-modified three-way junction (3WJ) DNA molecules with a topology similar to that of sialic acid binding sites. 3WJ DNA with three 2,3-SL residues on each DNA strand showed (8.0 * 104)-fold higher binding affinity for influenza virus A/Puerto Rico/08/34 (H1N1) compared to the 2,3-SL. This result indicated that the glycocluster effect due to clustering on one DNA arm and optimal spatial arrangement of the 3WJ DNA improved the weak interactions between a sialic acid and its binding site on HA. This 3WJ DNA compound has possible application as an inhibitor of influenza infection and for virus sensing. PMID- 29566329 TI - C(sp3)-H Azidation Reaction: A Protocol for Preparation of Aminals. AB - We report a protocol for the synthesis of N, N- and N, O-aminals via direct azidation of sp3 C-H bonds of substrates with an alpha-nitrogen or alpha-oxygen atom. A broad range of tetrahydroisoquinolines, tetrahydro-beta-carbolines, and cyclic benzyl ethers gave high yields under mild conditions. The protocol could be carried out on a gram scale without a decrease in the yield, and the aminal products could be readily transformed into complex aminals. PMID- 29566330 TI - Direct Electrochemical Sensing of Hydrogen Sulfide without Sulfur Poisoning. AB - An electrochemical method capable of direct, real-time detection of hydrogen sulfide was developed using triple pulse amperometry (TPA) to mitigate sulfur poisoning and its related passivation of the working electrode surface. Through repeated cycles of discrete potential pulses, the electrooxidation of surface adsorbed elemental sulfur to water-soluble sulfate ions was exploited to regenerate the glassy carbon electrode surface and maintain consistent sensor performance. Amperometric measurements and X-ray photoelectron spectroscopy surface analysis demonstrated that the TPA sensors provided enhanced analytical performance via decreased sulfur accumulation relative to low-potential (<=+0.7 V) constant potential amperometry. Sensors operated under optimized TPA parameters retained high sensitivity (57.4 +/- 13.0 nA/MUM), a wide linear dynamic range (150 nM-15 MUM), fast response times (<10 s), and a submicromolar detection limit (<100 nM) upon consecutive calibration cycles. The sensitivity and response time achieved were comparable to or better than current electrochemical sensors. Moreover, the simplicity of the method eliminates the need for external redox mediators or semipermeable membranes. PMID- 29566331 TI - Heteroarylguanidines as Allosteric Modulators of ASIC1a and ASIC3 Channels. AB - Acid-sensing ion channels (ASICs) are neuronal Na+-selective ion channels that open in response to extracellular acidification. They are involved in pain, fear, learning, and neurodegeneration after ischemic stroke. 2-Guanidine-4 methylquinazoline (GMQ) was recently discovered as the first nonproton activator of ASIC3. GMQ is of interest as a gating modifier and pore blocker of ASICs. It has however a low potency, and exerts opposite effects on ASIC1a and ASIC3. To further explore the molecular mechanisms of GMQ action, we have used the guanidinium moiety of GMQ as a scaffold and tested the effects of different GMQ derivatives on the ASIC pH dependence and maximal current. We report that GMQ derivatives containing quinazoline and quinoline induced, as GMQ, an alkaline shift of the pH dependence of activation in ASIC3 and an acidic shift in ASIC1a. Another group of 2-guanidinopyridines shifted the pH dependence of both ASIC1a and ASIC3 to more acidic values. Several compounds induced an alkaline shift of the pH dependence of ASIC1a/2a and ASIC2a/3 heteromers. Compared to GMQ, guanidinopyridines showed a 20-fold decrease in the IC50 for ASIC1a and ASIC3 current inhibition at pH 5. Strikingly, 2-guanidino-quinolines and -pyridines showed a concentration-dependent biphasic effect that resulted at higher concentrations in ASIC1a and ASIC3 inhibition (IC50 > 100 MUM), while causing at lower concentration a potentiation of ASIC1a, but not ASIC3 currents (EC50 ~ 10 MUM). In conclusion, we describe a new family of small molecules as ASIC ligands and identify an ASIC subtype-specific potentiation by a subgroup of these compounds.

AB - In this study, we assess the influence of solvation on the accuracy and reliability of isotropic nuclear magnetic shielding calculations for amino acids in comparison to experimental data. We focus particularly on the performance of solvation methods for different protonation states, as biological molecules occur almost exclusively in aqueous solution and are subject to protonation with pH. We identify significant shortcomings of current implicit solvent models and present a hybrid solvation approach that improves agreement with experimental data by taking into account the presence of direct interactions between amino acid protonation state and water molecules. PMID- 29566333 TI - Specific Ion Effects on Protein Thermal Aggregation from Dilute Solutions to Crowded Environments. AB - We have investigated specific ion effects on protein thermal aggregation from dilute solutions to crowded environments. Ovalbumin and poly(ethylene glycol) have been employed as the model protein and crowding agent, respectively. Our studies demonstrate that the rate-limiting step of ovalbumin thermal aggregation is changed from the aggregation of unfolded protein molecules to the unfolding of the protein molecules, when the solution conditions are varied from a dilute solution to a crowded environment. The specific ion effects acting on the thermal aggregation of ovalbumin generated by kosmotropic and chaotropic ions are different. The thermal aggregation of ovalbumin molecules is promoted by kosmotropic anions in dilute solutions via an increase in protein hydrophobic interactions. In contrast, ovalbumin thermal aggregation is facilitated by chaotropic ions in crowded environments through accelerated unfolding of protein molecules. Therefore, there are distinct mechanisms causing the ion specificities of protein thermal aggregation between dilute solutions and crowded environments. The ion specificities are dominated by ion-specific hydrophobic interactions between protein molecules and ion-specific unfolding of protein molecules in dilute solutions and crowded environments, respectively.

AB - We develop a methodology for direct molecular-level simulation of adiabatic expansion of gas through a small orifice to a vacuum. The gas attains supersonic speeds, cools, and nucleates. The proposed approach combines equations of frictionless fluid dynamics with molecular dynamics simulation in an expanding periodic box. There are two key components of the proposed algorithm: (i) a time reversible integrator tailored to an expanding system, and (ii) an iterative procedure employed to satisfy the condition of steady flow. For a conical nozzle (opening angle of 60 degrees ), the simulations with argon and water vapor predict cluster sizes in agreement with the experiment. Clusters of irregular shapes observed in the experiment [J. Lengyel et al. Phys. Rev. Lett. 2014, 112, 113401] are not reproduced. The role of friction, turbulence, and sonic boom originating at the sharp nozzle edge is discussed. PMID- 29566336 TI - A Four-Site Molecular Model for Simulations of Liquid Methanol and Water-Methanol Mixtures: MeOH-4P. AB - In this work, we present a new four-site potential for methanol, MeOH-4P, fitted to reproduce the dielectric constant epsilon, the surface tension gamma s, and the liquid density rho of the pure liquid at T = 298.15 K and p = 1 bar. The partial charges on each site were taken from the OPLS/2016 model with the only difference of putting the negative charge on the fourth site ( M) instead of on the O atom, as done in four-site water models. The original Lennard-Jones (LJ) parameters of OPLS/2016 for the methyl moiety (Me) were modified for the fitting of rho and gamma s, whereas the parameters of the TIP4P-FB water model were used for the O atom without change. Taking into account the energetic cost of the enhanced dipole relative to the isolated molecule, the results from simulations with this model showed good agreement with experiments for rho, alpha p, kappa T, C p, and Delta H v- l. Also, the temperature dependence of gamma s and epsilon is satisfactory in the interval between 260 and 360 K, and the critical point description is similar to that of OPLS/2016. It is shown that orientational correlations, described by the Kirkwood factor G k, play a prominent role in the appropriate description of dielectric constants in existing models; unfortunately, the enhancement of the dipole moment produced a low diffusion coefficient DMeOH; thus, a compromise was required between a good reproduction of epsilon and an acceptable DMeOH. The use of a fourth site resulted in a significant improvement for water-methanol mixtures described with TIP4P-FB and MeOH-4P, respectively, but required the modification of the LJ geometric combination rule to allow a good description of the methanol molar-fraction dependence of rho, epsilon, and methanol (water) diffusion coefficients DMeOH ( DH2O) and excess volume of mixing Delta Vmix in the entire range of composition. The resulting free energy of hydration Delta Ghyd shows excellent agreement with experiments in the interval between 280 and 360 K.

AB - Structure-based optimization was conducted to improve the potency, selectivity, and cell-based activities of beta-catenin/B-cell lymphoma 9 (BCL9) inhibitors based on the 4'-fluoro- N-phenyl-[1,1'-biphenyl]-3-carboxamide scaffold, which was designed to mimic the side chains of the hydrophobic alpha-helical hot spots at positions i, i + 3, and i + 7. Compound 29 was found to disrupt the beta catenin/BCL9 protein-protein interaction (PPI) with a Ki of 0.47 MUM and >1900 fold selectivity for beta-catenin/BCL9 over beta-catenin/E-cadherin PPIs. The proposed binding mode of new inhibitors was consistent with the results of site directed mutagenesis and structure-activity relationship studies. Cell-based studies indicated that 29 disrupted the beta-catenin/BCL9 interaction without affecting the beta-catenin/E-cadherin interaction, selectively suppressed transactivation of Wnt/beta-catenin signaling, downregulated expression of Wnt target genes, and inhibited viability of Wnt/beta-catenin-dependent cancer cells in dose-dependent manners. A comparison of the biochemical and cell-based assay results offered the directions for future inhibitor optimization.

AB - Galvanic replacement reactions dictated by deliberately designed nanoparticulate templates have emerged as a robust and versatile approach that controllably transforms solid monometallic nanocrystals into a diverse set of architecturally more sophisticated multimetallic hollow nanostructures. The galvanic atomic exchange at the nanoparticle/liquid interfaces induces a series of intriguing structure-transforming processes that interplay over multiple time and length scales. Using colloidal Au-Cu alloy and intermetallic nanoparticles as structurally and compositionally fine-tunable bimetallic sacrificial templates, we show that atomically intermixed bimetallic nanocrystals undergo galvanic replacement-driven structural transformations remarkably more complicated than those of their monometallic counterparts. We interpret the versatile structure transforming behaviors of the bimetallic nanocrystals in the context of a unified mechanistic picture that rigorously interprets the interplay of three key structure-evolutionary pathways: dealloying, Kirkendall diffusion, and Ostwald ripening. By deliberately tuning the compositional stoichiometry and atomic-level structural ordering of the Au-Cu bimetallic nanocrystals, we have been able to fine-maneuver the relative rates of dealloying and Kirkendall diffusion with respect to that of Ostwald ripening through which an entire family of architecturally distinct complex nanostructures are created in a selective and controllable manner upon galvanic replacement reactions. The insights gained from our systematic comparative studies form a central knowledge framework that allows us to fully understand how multiple classic effects and processes interplay within the confinement by a colloidal nanocrystal to synergistically guide the structural transformations of complex nanostructures at both the atomic and nanoparticulate levels.

AB - Two-dimensionally (2D) arrayed polystyrene (PS)/ruthenium oxide (RuO2) core/shell nanospheres are successfully prepared by the electrodeposition of RuO2 nanoparticles on a hexagonal close-packed PS monolayer. This nanosphere structure is entirely different from the structure previously reported for other transition metal oxides electrodeposited on the PS nanosphere arrays. The different growth behavior is analyzed, and a possible deposition mechanism is proposed based on the morphological evolution and photoelectron spectroscopy measurements. As an electrode for supercapacitors, this 2D arrayed nanosphere structure exhibits superior capacitive properties such as significantly large areal capacitance, tight binding with current collectors, and retarded saturation of the capacitance, compared to a planar RuO2 film electrode.

AB - The main goal of this study was to develop a straightforward and rapid microplate assay for measuring propidium iodide (PI) in C2C12 cells. The PI method has proven to be an efficient quantitative assay for analyzing cell viability through PI fluorescence analysis. Importantly, the protocol takes less than 30 min and the results are reproducible. C2C12 cells were exposed to an increasing concentration of palmitate for a period of 24 h to induce cell death, and the PI fluorescence increased in a concentration-dependent manner. Evaluation of mitochondrial function and the production of reactive oxygen species confirmed the deleterious effects of palmitate. Also, the microplate PI assay demonstrated high sensitivity, as indicated by the detection of modest fluctuations in cell viability in response to catalase overexpression in palmitate-treated cells. The microplate PI assay, therefore, offers an accurate method for use in in-vitro studies.

AB - This study was aimed to observe the effects of vitamin B1, vitamin B2, and niacin supplementation on hepatic gene expression profiles in mice exposed to acute hypoxia. Thirty mice were randomly divided into normal, acute hypoxia, and acute hypoxia plus vitamin B1, vitamin B2, and niacin supplementation groups and fed corresponding diets for 2 weeks and then exposed to a simulated altitude of 6000 m for 8 h. Hepatic gene expression profiles were analyzed using a microarray technique. Several biochemical markers were also assayed. The results showed that a total of 2476 genes were expressed differentially after acute hypoxia exposure (1508 upregulated genes and 968 downregulated genes). Compared with the acute hypoxia group, there were 1382 genes differentially expressed (626 upregulated genes and 756 downregulated genes) in the acute hypoxia plus vitamin B1, vitamin B2, and niacin supplementation group. Pathway analysis indicated that carbohydrate, lipid, and amino acid metabolism, as well as electron transfer chain, were improved to some extent after vitamin B1, vitamin B2, and niacin supplementation. Supportive results were obtained from biochemical assays. Our findings suggest that the supplementation of vitamin B1, vitamin B2, and niacin is beneficial in improving nutritional metabolism partly via gene expression under acute hypoxia condition.

AB - The present study investigated whether increasing morning rectal temperatures (Trec) to evening levels, or increasing morning and evening Trec to an "optimal" level (38.5 degrees C), resulting in increased muscle temperatures (Tm), would offset diurnal variation in repeated sprint (RS) performance in a causal manner. Twelve trained males underwent five sessions [age (mean +/- SD) 21.0 +/- 2.3 years, maximal oxygen consumption (VO2max) 60.0 +/- 4.4 mL.kg-1 min-1, height 1.79 +/- 0.06 m, body mass 78.2 +/- 11.8 kg]. These included control morning (M, 07:30 h) and evening (E, 17:30 h) sessions (5-min warm-up), and three further sessions consisting of a warm-up morning trial (ME, in 39-40 degrees C water) until Trec reached evening levels; two "optimal" trials in the morning and evening (M38.5 and E38.5, in 39-40 degrees C water) respectively, until Trec reached 38.5 degrees C. All sessions included 3 * 3-s task-specific warm-up sprints, thereafter 10 * 3-s RS with 30-s recoveries were performed a non motorised treadmill. Trec and Tm measurements were taken at the start of the protocol and following the warm-up periods. Values for Trec and Tm at rest were higher in the evening compared to morning values (0.48 degrees C and 0.69 degrees C, p < 0.0005). RS performance was lower (7.8-8.3%) in the M for distance covered (DC; p = 0.002), average power (AP; p = 0.029) and average velocity (AV; p = 0.002). Increasing Trec in the morning to evening values or optimal values (38.5 degrees C) did not increase RS performance to evening levels (p = 1.000). However, increasing Trec in the evening to "optimal" level through a passive warm up significantly reduced DC (p = 0.008), AP (p < 0.0005) and AV (p = 0.007) to values found in the M condition (6.0-6.9%). Diurnal variation in Trec and Tm is not wholly accountable for time-of-day oscillations in RS performance on a non motorised treadmill; the exact mechanism(s) for a causal link between central temperature and human performance are still unclear and require more research. PMID- 29566345 TI - Wnt-Responsive Odontoblasts Secrete New Dentin after Superficial Tooth Injury. AB - The objective of our experiments was to identify new therapeutic strategies to stimulate dentin formation in an adult tooth. To address this objective, we evaluated dentin production in 2 acute trauma models: one involving a pulp exposure and the other involving a superficial dentin injury. Molecular, cellular, and histologic analyses revealed that in response to a severe injury, where the pulp is exposed to the oral cavity, cell death is rampant and the repair response initiates from surviving pulp cells and, to a lesser extent, surviving odontoblasts. When an injury is superficial, as in the case of a dentin injury model, then disturbances are largely confined to pulp tissue immediately underneath the damaged dentin tubules. We found that the pulp remained vital and innervated; primary odontoblasts upregulated HIF1alpha; and the rate of mineralization was significantly increased. A tamoxifen-inducible Axin2CreERT2/+; R26R mTmG/+ reporter strain was then used to demonstrate that a population of long-lived Wnt-responsive odontoblasts, which secreted dentin throughout the life of the animal, were responsible for depositing new dentin in response to a superficial injury. Amplifying Wnt signaling in the pulp stimulates dentin secretion, and in the dentin injury model, we show that a liposomal formulation of human WNT3A protein passes through dentinal tubules and is capable of upregulating Wnt signaling in the pulp. These data provide strong proof of concept for a therapeutic pulp-capping material to stimulate Wnt signaling in odontoblasts and thus improve the pulp repair response.

EVs are released by most cell types, such as bone marrow stem cells, osteoblasts, osteoclasts, and immune cells. In bone remodeling microenvironments, EVs deliver specific proteins (e.g., tenascin C and Sema4D), microRNAs (e.g., miR-214-3p, miR-183-5p, and miR-196a), and other growth factors (e.g., bone morphogenetic protein 1 to 7 and transforming growth factor beta1) to osteoblasts and regulate bone formation. In addition, EVs can deliver cytokines, such as RANK (receptor activator of nuclear factor kappaB) and RANKL (RANK ligand), and microRNAs, such as miR-218 and miR-148a, to modulate osteoclast differentiation during bone resorption. EVs also transfer bioactive molecules and have targeted therapies in bone-related diseases. Moreover, bioactive molecules in EVs are biomarkers in bone-related diseases. We highlight the emerging role of EVs in bone remodeling during physiologic and pathologic conditions and summarize the role of EVs in tooth development and regeneration. At the end of this review, we discuss the challenges of EV application in the treatment of bone diseases. PMID- 29566347 TI - Facet Annotation by Extending CNN with a Matching Strategy. AB - Most community question answering (CQA) websites manage plenty of question-answer pairs (QAPs) through topic-based organizations, which may not satisfy users' fine grained search demands. Facets of topics serve as a powerful tool to navigate, refine, and group the QAPs. In this work, we propose FACM, a model to annotate QAPs with facets by extending convolution neural networks (CNNs) with a matching strategy. First, phrase information is incorporated into text representation by CNNs with different kernel sizes. Then, through a matching strategy among QAPs and facet label texts (FaLTs) acquired from Wikipedia, we generate similarity matrices to deal with the facet heterogeneity. Finally, a three-channel CNN is trained for facet label assignment of QAPs. Experiments on three real-world data sets show that FACM outperforms the state-of-the-art methods. PMID- 29566348 TI - Optimizing the Usability of Brain-Computer Interfaces. AB - Brain-computer interfaces are in the process of moving from the laboratory to the clinic. These devices act by reading neural activity and using it to directly control a device, such as a cursor on a computer screen. An open question in the field is how to map neural activity to device movement in order to achieve the most proficient control. This question is complicated by the fact that learning, especially the long-term skill learning that accompanies weeks of practice, can allow subjects to improve performance over time. Typical approaches to this problem attempt to maximize the biomimetic properties of the device in order to limit the need for extensive training. However, it is unclear if this approach would ultimately be superior to performance that might be achieved with a nonbiomimetic device once the subject has engaged in extended practice and learned how to use it. Here we approach this problem using ideas from optimal control theory. Under the assumption that the brain acts as an optimal controller, we present a formal definition of the usability of a device and show that the optimal postlearning mapping can be written as the solution of a constrained optimization problem. We then derive the optimal mappings for particular cases common to most brain-computer interfaces. Our results suggest that the common approach of creating biomimetic interfaces may not be optimal when learning is taken into account. More broadly, our method provides a blueprint for optimal device design in general control-theoretic contexts. PMID- 29566349 TI - An Interneuron Circuit Reproducing Essential Spectral Features of Field Potentials. AB - Recent advances in engineering and signal processing have renewed the interest in invasive and surface brain recordings, yet many features of cortical field potentials remain incompletely understood. In the computational study that follows, we show that a model circuit of interneurons, coupled via both GABAA receptor synapses and electrical synapses, reproduces many essential features of the power spectrum of local field potential (LFP) recordings, such as 1/ f power scaling at low frequency (below 10 Hz), power accumulation in the gamma-frequency band (30-100 Hz), and a robust alpha rhythm in the absence of stimulation. The low-frequency 1/ f power scaling depends on strong reciprocal inhibition, whereas the alpha rhythm is generated by electrical coupling of intrinsically active neurons. As in previous studies, the gamma power arises through the amplification of single-neuron spectral properties, owing to the refractory period, by parameters that favor neuronal synchrony, such as delayed inhibition. This study also confirms that both synaptic and voltage-gated membrane currents contribute substantially to the LFP and that high-frequency signals such as action potentials quickly taper off with distance. Given the ubiquity of electrically coupled interneuron circuits in the mammalian brain, they may be major determinants of the recorded potentials. PMID- 29566350 TI - Hidden Quantum Processes, Quantum Ion Channels, and 1/ ftheta-Type Noise. AB - In this letter, we perform a complete and in-depth analysis of Lorentzian noises, such as those arising from [Formula: see text] and [Formula: see text] channel kinetics, in order to identify the source of [Formula: see text]-type noise in neurological membranes. We prove that the autocovariance of Lorentzian noise depends solely on the eigenvalues (time constants) of the kinetic matrix but that the Lorentzian weighting coefficients depend entirely on the eigenvectors of this matrix. We then show that there are rotations of the kinetic eigenvectors that send any initial weights to any target weights without altering the time constants. In particular, we show there are target weights for which the resulting Lorenztian noise has an approximately [Formula: see text]-type spectrum. We justify these kinetic rotations by introducing a quantum mechanical formulation of membrane stochastics, called hidden quantum activated-measurement models, and prove that these quantum models are probabilistically indistinguishable from the classical hidden Markov models typically used for ion channel stochastics. The quantum dividend obtained by replacing classical with quantum membranes is that rotations of the Lorentzian weights become simple readjustments of the quantum state without any change to the laboratory determined kinetic and conductance parameters. Moreover, the quantum formalism allows us to model the activation energy of a membrane, and we show that maximizing entropy under constrained activation energy yields the previous [Formula: see text]-type Lorentzian weights, in which the spectral exponent [Formula: see text] is a Lagrange multiplier for the energy constraint. Thus, we provide a plausible neurophysical mechanism by which channel and membrane kinetics can give rise to [Formula: see text]-type noise (something that has been occasionally denied in the literature), as well as a realistic and experimentally testable explanation for the numerical values of the spectral exponents. We also discuss applications of quantum membranes beyond [Formula: see text]-type -noise, including applications to animal models and possible impact on quantum foundations. PMID- 29566351 TI - Pattern Storage, Bifurcations, and Groupwise Correlation Structure of an Exactly Solvable Asymmetric Neural Network Model. AB - Despite their biological plausibility, neural network models with asymmetric weights are rarely solved analytically, and closed-form solutions are available only in some limiting cases or in some mean-field approximations. We found exact analytical solutions of an asymmetric spin model of neural networks with arbitrary size without resorting to any approximation, and we comprehensively studied its dynamical and statistical properties. The network had discrete time evolution equations and binary firing rates, and it could be driven by noise with any distribution. We found analytical expressions of the conditional and stationary joint probability distributions of the membrane potentials and the firing rates. By manipulating the conditional probability distribution of the firing rates, we extend to stochastic networks the associating learning rule previously introduced by Personnaz and coworkers. The new learning rule allowed the safe storage, under the presence of noise, of point and cyclic attractors, with useful implications for content-addressable memories. Furthermore, we studied the bifurcation structure of the network dynamics in the zero-noise limit. We analytically derived examples of the codimension 1 and codimension 2 bifurcation diagrams of the network, which describe how the neuronal dynamics changes with the external stimuli. This showed that the network may undergo transitions among multistable regimes, oscillatory behavior elicited by asymmetric synaptic connections, and various forms of spontaneous symmetry breaking. We also calculated analytically groupwise correlations of neural activity in the network in the stationary regime. This revealed neuronal regimes where, statistically, the membrane potentials and the firing rates are either synchronous or asynchronous. Our results are valid for networks with any number of neurons, although our equations can be realistically solved only for small networks. For completeness, we also derived the network equations in the thermodynamic limit of infinite network size and we analytically studied their local bifurcations. All the analytical results were extensively validated by numerical simulations. PMID- 29566352 TI - Deep Semisupervised Zero-Shot Learning with Maximum Mean Discrepancy. AB - Due to the difficulty of collecting labeled images for hundreds of thousands of visual categories, zero-shot learning, where unseen categories do not have any labeled images in training stage, has attracted more attention. In the past, many studies focused on transferring knowledge from seen to unseen categories by projecting all category labels into a semantic space. However, the label embeddings could not adequately express the semantics of categories. Furthermore, the common semantics of seen and unseen instances cannot be captured accurately because the distribution of these instances may be quite different. For these issues, we propose a novel deep semisupervised method by jointly considering the heterogeneity gap between different modalities and the correlation among unimodal instances. This method replaces the original labels with the corresponding textual descriptions to better capture the category semantics. This method also overcomes the problem of distribution difference by minimizing the maximum mean discrepancy between seen and unseen instance distributions. Extensive experimental results on two benchmark data sets, CU200-Birds and Oxford Flowers 102, indicate that our method achieves significant improvements over previous methods. PMID- 29566353 TI - Slowness as a Proxy for Temporal Predictability: An Empirical Comparison. AB - The computational principles of slowness and predictability have been proposed to describe aspects of information processing in the visual system. From the perspective of slowness being a limited special case of predictability we investigate the relationship between these two principles empirically. On a collection of real-world data sets we compare the features extracted by slow feature analysis (SFA) to the features of three recently proposed methods for predictable feature extraction: forecastable component analysis, predictable feature analysis, and graph-based predictable feature analysis. Our experiments show that the predictability of the learned features is highly correlated, and, thus, SFA appears to effectively implement a method for extracting predictable features according to different measures of predictability. PMID- 29566354 TI - Novel Perceptually Uniform Chromatic Space. AB - Chromatically perceptive observers are endowed with a sense of similarity between colors. For example, two shades of green that are only slightly discriminable are perceived as similar, whereas other pairs of colors, for example, blue and yellow, typically elicit markedly different sensations. The notion of similarity need not be shared by different observers. Dichromat and trichromat subjects perceive colors differently, and two dichromats (or two trichromats, for that matter) may judge chromatic differences inconsistently. Moreover, there is ample evidence that different animal species sense colors diversely. To capture the subjective metric of color perception, here we construct a notion of distance in color space based on the physiology of the retina, and is thereby individually tailored for different observers. By applying the Fisher metric to an analytical model of color representation, we construct a notion of distance that reproduces behavioral experiments of classical discrimination tasks. We then derive a coordinate transformation that defines a new chromatic space in which the Euclidean distance between any two colors is equal to the perceptual distance, as seen by one individual subject, endowed with an arbitrary number of color sensitive photoreceptors, each with arbitrary absorption probability curves and appearing in arbitrary proportions. PMID- 29566355 TI - Predictive Coding in Area V4: Dynamic Shape Discrimination under Partial Occlusion. AB - The primate visual system has an exquisite ability to discriminate partially occluded shapes. Recent electrophysiological recordings suggest that response dynamics in intermediate visual cortical area V4, shaped by feedback from prefrontal cortex (PFC), may play a key role. To probe the algorithms that may underlie these findings, we build and test a model of V4 and PFC interactions based on a hierarchical predictive coding framework. We propose that probabilistic inference occurs in two steps. Initially, V4 responses are driven solely by bottom-up sensory input and are thus strongly influenced by the level of occlusion. After a delay, V4 responses combine both feedforward input and feedback signals from the PFC; the latter reflect predictions made by PFC about the visual stimulus underlying V4 activity. We find that this model captures key features of V4 and PFC dynamics observed in experiments. Specifically, PFC responses are strongest for occluded stimuli and delayed responses in V4 are less sensitive to occlusion, supporting our hypothesis that the feedback signals from PFC underlie robust discrimination of occluded shapes. Thus, our study proposes that area V4 and PFC participate in hierarchical inference, with feedback signals encoding top-down predictions about occluded shapes. PMID- 29566356 TI - Designing Patient-Specific Optimal Neurostimulation Patterns for Seizure Suppression. AB - Neurostimulation is a promising therapy for abating epileptic seizures. However, it is extremely difficult to identify optimal stimulation patterns experimentally. In this study, human recordings are used to develop a functional 24 neuron network statistical model of hippocampal connectivity and dynamics. Spontaneous seizure-like activity is induced in silico in this reconstructed neuronal network. The network is then used as a testbed to design and validate a wide range of neurostimulation patterns. Commonly used periodic trains were not able to permanently abate seizures at any frequency. A simulated annealing global optimization algorithm was then used to identify an optimal stimulation pattern, which successfully abated 92% of seizures. Finally, in a fully responsive, or closed-loop, neurostimulation paradigm, the optimal stimulation successfully prevented the network from entering the seizure state. We propose that the framework presented here for algorithmically identifying patient-specific neurostimulation patterns can greatly increase the efficacy of neurostimulation devices for seizures. PMID- 29566357 TI - Solving Constraint-Satisfaction Problems with Distributed Neocortical-Like Neuronal Networks. AB - Finding actions that satisfy the constraints imposed by both external inputs and internal representations is central to decision making. We demonstrate that some important classes of constraint satisfaction problems (CSPs) can be solved by networks composed of homogeneous cooperative-competitive modules that have connectivity similar to motifs observed in the superficial layers of neocortex. The winner-take-all modules are sparsely coupled by programming neurons that embed the constraints onto the otherwise homogeneous modular computational substrate. We show rules that embed any instance of the CSP's planar four-color graph coloring, maximum independent set, and sudoku on this substrate and provide mathematical proofs that guarantee these graph coloring problems will convergence to a solution. The network is composed of nonsaturating linear threshold neurons. Their lack of right saturation allows the overall network to explore the problem space driven through the unstable dynamics generated by recurrent excitation. The direction of exploration is steered by the constraint neurons. While many problems can be solved using only linear inhibitory constraints, network performance on hard problems benefits significantly when these negative constraints are implemented by nonlinear multiplicative inhibition. Overall, our results demonstrate the importance of instability rather than stability in network computation and offer insight into the computational role of dual inhibitory mechanisms in neural circuits. PMID- 29566358 TI - Partnering with consumers in the public reporting of quality of care: review of the Victorian quality of care reports. AB - Objective The aim of the present study was to investigate whether the content of annual Victorian quality of care reports had an increased consumer participation focus following the introduction of the National Safety and Quality Health Service (NSQHS) Partnering with Consumers standard.Methods A mixed-methods approach comprising a comparative descriptive observational study design with quantitative data analysis was used. Nine large Victorian metropolitan public health services' annual quality of care reports from 2011 and 2014 were analysed using a newly devised analysis framework consisting of elements of the NSQHS 'Partnering with Consumers' standard and minimal requirements for Quality of Care reporting by the Department of Health and Human Services.Results Of the nine 2014 quality of care reports, in only three were total scores higher compared with scores in the 2011 reports; in one of the 2014 reports, the total scores remained the same, and in the remaining five reports total scores were lower than in the 2011 reports. Overall, there was an improved total score for the 2014 reports compared with the 2011 reports, corresponding to a higher consumer participation focus.Conclusion Overall, the present study demonstrated mixed findings and, in some cases, lower scores for the 2014 reports, which was after the introduction of the Partnering with Consumers NSQHS standard, compared with the 2011 reports. Overall, there is future scope to enhance the degree of consumer participation evident within the quality of care reports.What is known about the topic? Partnering with consumers has been associated with improved clinical outcomes, decreased readmission rates and rates of hospital-acquired infections, and improved adherence to treatment recommendations and health literacy. Engaging consumers has been recognised as a means to increase the accessibility and appropriateness of healthcare to individuals. Public reporting is a tool through which health services communicate with and engage their consumers in order to improve the quality of care they provide, and is a key element in Australia of the NSQHS Partnering with Consumers standard.What does the paper add? This paper links the principles of consumer participation with public reporting. The paper highlights the potential for healthcare organisations to use their public reporting media to engage with consumers and communicate about the quality of care they deliver.What are the implications for practitioners? The unexpected findings of a lower emphasis on consumer participation suggests the need for Victorian health services to review the purpose and processes for developing the publicly reported quality of care reports in order to improve their compliance. PMID- 29566359 TI - Does the professional attitude of physicians always affect their professional behaviour? A survey in tertiary hospitals in Nanchang City, China. AB - Objective Understanding the effect of professional attitude on professional behaviour is conducive to the development of targeted measures to promote professionalism. The aim of the present study was to explore the effect of professional attitude on professional behaviour.Methods Using a self-reported questionnaire, 212 physicians were surveyed using quota sampling in six tertiary hospitals in Nanchang City. The effect of professional attitude on professional behaviour was analysed through logistic regression analysis.Results Providing necessary care regardless of a patient's ability to pay, working on quality improvement initiatives, informing patients of medical errors and reporting incompetent colleagues had significant positive effects on corresponding professional behaviour (odds ratios (95% confidence intervals) 11.06 (3.78, 32.40), 9.42 (1.93, 46.01), 4.04 (1.29, 12.63) and 5.51 (1.26, 24.08) respectively). However, attitudes towards minimising disparities in care, undergoing periodic recertification examinations and reporting medical errors did not significantly affect corresponding professional behaviour.Conclusions Professional attitude affects professional behaviour, but such an effect varies with different professional norms. These findings imply that improving the professional attitude is useful but insufficient to promote medical professionalism. A management system conducive to the conversion of professional attitude to professional behaviour should be established.What is known about the topic? Several studies have affirmed that Chinese physicians accept most areas of medical professionalism embodied in the Charter on Medical Professionalism. However, only a few published studies have examined the effect of professional attitude on professional behaviour. Understanding the effect of professional attitude on professional behaviour is conducive to the development of targeted measures to promote professionalism. The present study attempted to fill the current knowledge gaps.What does this paper add? The study surveyed professional attitudes and behaviour of Chinese physicians and explored the effects of the former on the latter. The study found that professional attitude affects professional behaviour, but such an effect varies with different professional norms. The results may help establish fundamental problems in the professionalism of physicians and in measures to promote professional behaviour not only in China, but also in other countries.What are the implications for practitioners? The implications for hospital managers and policy makers are that improving professional attitude is useful but insufficient to promote medical professionalism. A management system conducive to the conversion of professional attitude to professional behaviour should be established. PMID- 29566361 TI - Prof. Hans R. Muhlemann (1917-1997). PMID- 29566360 TI - The Antimuscarinic Agent Tolterodine Regulates Bladder Extracellular Matrix in Partial Bladder Outlet Obstruction in Rats. AB - BACKGROUND/AIMS: Antimuscarinic agents can delay the progression of bladder dysfunction caused by bladder outlet obstruction (BOO). To date, the relationship between muscarinic receptor activity and the bladder extracellular matrix (ECM) remains unclear. Thus, an animal model of partial BOO (PBOO) in female rats was established to explore the variation in bladder wall ECM proteins under PBOO conditions with antimuscarinic agent administration. METHODS: Rats were randomly divided into three groups: sham, PBOO, and PBOO plus tolterodine. Picrosirius red staining was used to examine the smooth muscle and collagen content of bladder samples. Gene microarray and RT-PCR were performed to survey the expression of ECM proteins, receptors, and metabolism regulators in the rat bladder. Positive results were further evaluated by immunohistochemistry. RESULTS: Picrosirius red staining showed that smooth muscle volume significantly increased in the PBOO and PBOO plus tolterodine groups (p < 0.05), while collagen significantly increased in the PBOO group (p < 0.05) but not in the PBOO plus tolterodine group. Gene microarray and RT-PCR revealed that none of the collagen subtypes exhibited significant changes after PBOO establishment and tolterodine administration. However, matrix metalloproteinases (MMPs) increased significantly in the PBOO plus tolterodine group (p < 0.05). Additionally, PBOO inhibited the expression of non-collagen ECM proteins in the rat bladder wall, while tolterodine induced the expression of non-collagen ECM proteins and ECM receptors. CONCLUSIONS: Tolterodine decreased the volume of collagen in PBOO rat bladder wall, possibly via MMPs, and regulated the expression of ECM proteins and receptors.

PMID- 29566363 TI - Cardiac-Specific Overexpression of Silent Information Regulator 1 Protects Against Heart and Kidney Deterioration in Cardiorenal Syndrome via Inhibition of Endoplasmic Reticulum Stress. AB - BACKGROUND/AIMS: Increased endoplasmic reticulum (ER) stress contributes to development of cardiorenal syndrome (CRS), and Silent Information Regulator 1 (SIRT1), a class III histone deacetylase, may have protective effects on heart and renal disease, by reducing ER stress. We aimed to determine if SIRT1 alleviates CRS through ER stress reduction. METHODS: Wild type mice (n=37), mice with cardiac-specific SIRT1 knockout (n=29), or overexpression (n=29), and corresponding controls, were randomized into four groups: sham MI (myocardial infarction) +sham STNx (subtotal nephrectomy); MI+sham STNx; sham MI+STNx; and MI+STNx. To establish the CRS model, subtotal nephrectomy (5/6 nephrectomy, SNTx) and myocardial infarction (MI) (induced by ligation of the left anterior descending (LAD) coronary artery) were performed successively to establish CRS model. At week 8, the mice were sacrificed after sequential echocardiographic and hemodynamic studies, and then pathology and Western-blot analysis were performed. RESULTS: Neither MI nor STNx alone significantly influenced the other healthy organ. However, in MI groups, STNx led to more severe cardiac structural and functional deterioration, with increased remodeling, increased BNP levels, and decreased EF, Max +dp/dt, and Max -dp/dt values than in sham MI +STNx groups. Conversely, in STNx groups, MI led to renal structural and functional deterioration, with more severe morphologic changes, augmented desmin and decreased nephrin expression, and increased BUN, SCr and UCAR levels. In MI+STNx groups, SIRT1 knockout led to more severe cardiac structural and functional deterioration, with higher Masson-staining score and BNP levels, and lower EF, FS, Max +dp/dt, and Max -dp/dt values; while SIRT1 overexpression had the opposite attenuating effects. In kidney, SIRT1 knockout resulted in greater structural and functional deterioration, as evidenced by more severe morphologic changes, higher levels of UACR, BUN and SCr, and increased desmin and TGF-beta expression, while SIRT1 overexpression resulted in less severe morphologic changes and increased nephrin expression without significant influence on BUN or SCr levels. The SIRT1 knockout but not overexpression resulted in increased myocardial expression of CHOP and GRP78. Cardiac-specific SIRT1 knockout or overexpression resulted in increased or decreased renal expression of CHOP, Bax, and p53 respectively. CONCLUSIONS: Myocardial SIRT1 activation appears protective to both heart and kidney in CRS models, probably through modulation of ER stress. PMID- 29566364 TI - The Immunogenicity and Anti-Tumor Efficacy of a Rationally Designed EGFR Vaccine. AB - BACKGROUND/AIMS: The abnormally activated EGFR promotes tumor growth, invasion and metastasis. Current therapeutics targeting EGFR have markedly improved the clinical outcome, but they are limited in use due to transient efficacy, frequent administration, high cost and significant toxicity. METHODS: We rationally designed a multiepitope immunogen against EGFR, named as DEGFRm. The immunogen is composed of an epitope peptide (EGFR265-283) and the extracellular domain III (EGFR334-505) of mouse EGFR. EGFR265-283 is grafted onto the translocation domain of diphtheria toxin (DTT), and EGFR334-505 is fused to C-terminal of DTT. Next, the immunogenicity and anti-tumor efficacies of DEGFRm vaccine were examined in mouse tumor models. RESULTS: When formulated with Alum and CpG, DEGFRm vaccine elicits Th 1 immune responses and inhibits tumor growth in both prophylactic and therapeutic mouse tumor models. Moreover, the tumor microvasculature is markedly reduced and the tumor infiltration of CD8+ T lymphocytes is greatly enhanced. CONCLUSIONS: These data suggest that active immunization with DEGFRm vaccine is a promising strategy for therapy of various EGFR+ cancers. PMID- 29566365 TI - Attenuation of MicroRNA-495 Derepressed PTEN to Effectively Protect Rat Cardiomyocytes from Hypertrophy. AB - BACKGROUND: The effect of microRNA (miR)-495 on cardiomyocyte hypertrophy was explored by investigating the expression of proteins in the phosphatidylinositol 3-kinase (PI3K)/Akt signal pathway. METHODS: The study used a rat model of pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT) administration (60 mg/kg) for 2 weeks. Arterial wall thickness and right ventricular hypertrophy were examined by hematoxylin and eosin (HE) staining in the lungs and hearts. The expression level of miR-495 and PTEN was analyzed by quantitative (q)PCR and Western blotting. From the cellular level, we used loss of-function approaches to investigate the functional roles of miR-495 in cardiac hypertrophy induced by angiotensin II (Ang II) with immunofluorescence, qPCR, and Western blotting. RESULTS: The results showed that upregulation of miR-495 markedly influenced the expression of hypertrophic markers, including the induction of nppa and the inhibition of myh6. In contrast, a reduction in the level of miR-495 attenuated an Ang II-induced hypertrophic reaction. Furthermore, PTEN was identified as a potential target of miR-495 by a bioinformatics algorithm. Luciferase analysis and Western blot analysis confirmed that the contribution of miR-495 to cardiomyocyte hypertrophy may partly be through targeting PTEN. CONCLUSIONS: Attenuation of miR-495 derepressed PTEN to effectively protect rat cardiomyocytes from hypertrophy. PMID- 29566366 TI - Psychosocial-Stress, Liver Regeneration and Weight Gain: a Conspicuous Pathophysiological Triad. AB - Psychosocial stress alters several physiological parameters resulting in multiple disorders, particularly compromising the immune system thereby provoking various diseases including liver disorders. However, the plausible underlying mechanisms remain elusive. Recent literature provides mechanistic evidences of detrimental effects of psychosocial stress on physiology of different body organs including liver. The data of stress-induced pathophysiological changes in liver functions and obesity were systematically collected from PubMed, ScienceDirect and the Web of Science Databases published in English. Stress and glucocorticoids (GCs) control food intake and energy expenditure through appetite stimulators neuropeptide Y (NYP) and agouti-related protein (AgRP) in hypothalamus. Principle effectors of the activated hypothalamic-pituitary-adrenal (HPA) axis in response to psychosocial stress are proopiomelanocortin (POMC)-derived adrenocorticotropic hormone (ACTH) and GCs. Stress-induced GCs hyper-secretion triggers glucocorticoid receptor (GR)-dependent transcriptional factor, nuclear factor kappa B (NFkappaB), which interferes TNFalpha-IL6 and keap1-Nrf2 pathways in liver regeneration and obesity through fine-tuning of TNFalpha, IL6 and Nrf2 signaling. In this review, it is contrived upon existing evidence to put forward a model whereby exposure to life-stress has a prominent impact over weight gain and can alter the regenerative mode of a damaged liver through Keap1-Nrf2 and TNFa-IL6 pathways. PMID- 29566367 TI - Defective Circulating Regulatory B Cells in Patients with Dilated Cardiomyopathy. AB - BACKGROUND/AIMS: Newly identified IL-10-producing regulatory B cells (Bregs) have been shown to play an important role in the suppression of immune responses. Chronic immune activation participates in the pathogenesis of dilated cardiomyopathy (DCM) but whether Bregs are involved in its development remains unclear. We aimed to investigate the circulating frequency and function of Bregs in DCM. METHODS: In total, 35 DCM patients (20 men and 15 women) and 44 healthy controls (23 men and 21 women) were included in the experiment, and the frequency of Bregs was detected using flow cytometry. RESULTS: According to our results, the frequency of circulating IL-10-producing Bregs was significantly lower in DCM patients compared with healthy controls. Furthermore, the CD24hiCD27+ B cell subset in which IL-10-producing Bregs were mainly enriched from DCM patients showed impaired IL-10 expression and a decreased ability to suppress the TNF alpha production of CD4+CD25- Tconv cells and to maintain Tregs differentiation. Correlation analysis showed that the frequency of IL-10-producing Bregs and the suppressive function of CD24hiCD27+ B cells were positively correlated with left ventricular ejection fraction and negatively correlated with NT-proBNP in DCM patients. CONCLUSIONS: In conclusion, the reduced frequency and impaired functions suggest a potential role of Bregs in the development of DCM. PMID- 29566369 TI - Clinicopathological Characteristics, Surgical Treatments, and Survival Outcomes of Patients with Duodenal Gastrointestinal Stromal Tumor. AB - BACKGROUND: Duodenal gastrointestinal stromal tumors (GISTs) are rare and their clinicopathological features have not been completely described. In this retrospective study, we examined the characteristics and long-term outcomes of patients who underwent surgical treatment for duodenal GISTs. METHODS: We examined patients surgically treated for duodenal GISTs from 1999 to 2016 at the China National Cancer Center. We analyzed patient characteristics, treatments, histological examinations, and survival outcomes. RESULTS: The 52 surgeries performed included 14 pancreaticoduodenectomies (26.9%), 37 limited resections (71.2%), and one palliative bypass procedure (1.9%). No surgery-related death occurred. The complication rate in patients who underwent pancreaticoduodenectomy was slightly higher than that in patients who underwent limited resection. The 5 year overall survival and progression-free survival rates for patients with duodenal adenocarcinoma were 89.1 and 72.9%, respectively. The overall survival and progression-free survival rates were not significantly related to surgical methods. Large tumor size and high mitotic rate were associated with poor overall survival outcomes. However, no independent factor was associated with prognosis, which may be due to the small sample size. CONCLUSION: The prognosis of duodenal gastrointestinal stromal tumors was good. Limited resection seems to be oncologically feasible, with outcomes being less worse than those of pancreaticoduodenectomy. PMID- 29566368 TI - The Trend of beta3-Adrenergic Receptor in the Development of Septic Myocardial Depression: A Lipopolysaccharide-Induced Rat Septic Shock Model. AB - Septic shock with low cardiac output is very common in children. However, the mechanism underlying myocardial depression is unclear. The role of beta3-AR in the development of myocardial depression in sepsis is unknown. In the present study, we generated an adolescent rat model of hypodynamic septic shock induced by lipopolysaccharide (LPS). Neonatal cardiomyocytes were also treated with LPS to mimic myocardial depression in sepsis, which was confirmed via an in vivo left ventricular hemodynamic study, and measurements of contractility and the Ca2+ transient in isolated adolescent and neonatal cardiomyocytes. After 16 h of LPS treatment, cultured neonatal cardiomyocytes showed a diminished Ca2+ transient amplitude associated with an increase in the beta3-AR level. With the addition of a beta3-AR agonist, the Ca2+ transient in LPS-treated neonatal rat cardiomyocytes gradually decreased over time; such a change was absent in cells treated with nitric oxide synthase (NOS) inhibitors prior to treatment with a beta3-AR agonist. In adolescent rats with septic myocardial depression, cardiac function declined as indicated by decreased MAP, dP/dtmax, and dP/dtmix for 6 h after LPS injection; however, the beta3-AR level first increased 2 h after LPS treatment and then decreased 6 h after LPS treatment in the absence of exogenous catecholamines. The results indicate that, in vitro, at the cellular level beta3 AR may be involved in the development of myocardial depression (Ca2+ transient depression) in sepsis through NOS signaling pathways; however, in vivo, a complicated mechanism for modulating beta3-AR may exist. PMID- 29566370 TI - Dermoscopic Features of Basal Cell Carcinoma on the Lower Limbs: A Chameleon! AB - BACKGROUND: Lower limbs represent an uncommon location for basal cell carcinoma (BCC) and only few reports have described dermoscopic features of BCC in this body site. Since BCCs of the lower limbs frequently display nonclassic BCC dermoscopic criteria, they can simulate other benign or malignant lesions. OBJECTIVE: Our aim was to describe the dermoscopic features of BCC located on lower limbs and to define which criteria were more associated with their benign- or malignant-looking appearance. METHODS: We conducted a retrospective study enrolling consecutive patients with histologically confirmed BCCs of the lower limbs. Lesions were classified in 7 categories according to the clinical and dermoscopic global appearance. Clear BCC, squamous cell carcinoma (SCC) or Bowen disease-like, Kaposi disease-like, melanoma-like, and aspecific pattern were considered malignant-looking lesions; however, seborrheic keratosis-like and dermatofibroma-like were considered benign-looking. To define which dermoscopic criteria were independently associated with benign- or malignant-looking appearance, we conducted a multivariate logistic regression analysis. RESULTS: A total of 81 BCCs were enrolled: 18 (22%) were benign-looking lesions (of which 11 were seborrheic keratosis-like and 7 dermatofibroma-like) and 63 (78%) were malignant-looking BCCs (of which 24 were clear-cut BCCs, 23 SCC-like, 2 Kaposi disease-like, 9 melanoma-like, and 5 had aspecific pattern). Multivariate regression analysis showed that erosions/ulceration and vessels were independently associated with malignant-looking appearance. The most represented vessels were glomerular and polymorphic, which are more frequently encountered in SCC, together with ulceration. CONCLUSION: BCC of the lower legs frequently simulates other benign or malignant lesions, with SCC being the main differential diagnosis. PMID- 29566371 TI - Influence of Visceral Fat in the Outcomes of Colorectal Cancer. AB - AIM: To determine the relationship of visceral fat (VF) with the surgical outcome of the patients with colorectal cancer (CRC) submitted to curative surgery. METHODS: Retrospective analysis of all patients submitted to CRC surgery during 3 years with a minimum of 5 years of follow-up. We assessed the length of hospital stay, complications, pathologic reports, surgical re-interventions and hospital re-admissions, relapses, survival time and disease-free time. VF was calculated based on patients' pre-operative CT-scan. The patients were divided into quartiles according to the VF area. Linear regression models and logistic regression models were used to establish a relationship between VF and all data collected. RESULTS: The study included 199 patients (129 with colon cancer [CC] and 70 with rectal cancer). The average area of VF was 115.7 cm2. Patients with CRC revealed a direct relationship between VF and postoperative complications (p = 0.043), anastomotic leakage (p = 0.009) and re-operation (p = 0.005). The subgroup of patients with CC had an inverse association between VF and lymph nodes harvested (p = 0.027). Survival analyses did not reveal significant differences. CONCLUSION: VF has an influence on postoperative complications, anastomotic leakage and re-operation. A negative influence of VF on lymph nodes harvested was observed on CC patients. PMID- 29566372 TI - Prevalence, Recognition, and Treatment of Dementia in Assisted Living Facilities. AB - BACKGROUND/AIMS: Dementia and psychiatric disorders are common in assisted living facilities (ALFs) and have suboptimal rates of recognition and treatment. Therefore, we aimed to obtain a direct estimate of the prevalence of cognitive impairment and especially dementia among residents of ALFs in western Slovakia and their rates of primary recognition and adequate treatment. METHODS: We conducted two cross-sectional studies. Ten ALFs within the city of Bratislava were chosen for the study in 2004, and again in 2011. A total of 866 residents in ALFs were examined in 2004, and 821 residents in ALFs were examined in 2011. The rate and characterization of dementia, its primary recognition and adequate treatment were investigated in both cross-sectional studies. RESULTS: In 2004, 57% of the participants had dementia. Only 7.2% of the participants with probable Alzheimer disease were treated with acetylcholinesterase inhibitors. In 2011, we observed a significant improvement in primary diagnostics and therapy. 66.9% of the cases of dementia were adequately evaluated, and 52.1% were adequately treated. CONCLUSION: Cognitive deficit and dementia are significantly underdiagnosed and undertreated in assisted living settings. In the second cross sectional study we detected significant but not complete improvement in the primary recognition and adequate therapy of dementia. PMID- 29566373 TI - Reclassification of Chronic Kidney Disease Stage, Eligibility for Cystatin-C and Its Associated Costs in a UK Primary Care Cohort. AB - BACKGROUND AND AIMS: Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) estimations of glomerular filtration rate (eGFR), compared to modification of diet in renal disease (MDRD), have superior performance in predicting renal, cardiovascular and mortality events. Cystatin-C further improves prediction. Our primary aim was to assess the change in prevalence and classification of CKD in converting from MDRD to CKD-EPI in an unselected primary care CKD population. Our secondary aims were to determine the eligibility for cystatin-C testing based on National Institute for Health and Care Excellence guidance and the associated costs. METHODS: eGFR data from an unselected UK primary care CKD cohort was studied to assess reclassification of CKD stages from MDRD to CKD-EPI, suitability for cystatin-C testing and its associated cost. RESULTS: A total number of 24,660 individuals had >=2 MDRD eGFR results <60 mL/min/1.73 m2 >3 months apart (7.0% of adult population). The mean age was 75.2 (SD 11.4 years) with 15,265 (61.9%) females. Mean eGFR was 2.88 mL/min/1.73 m2 lower with CKD-EPI eGFR versus MDRD eGFR (49.7 vs. 46.8, t test p < 0.0001, 95% CI 2.85-2.91). 12.0% of individuals were re-categorised to a more or less advanced CKD stage, and 1.3% to a less advanced stage. The percentage of the population categorised as 3a-A1 CKD-EPI and therefore potentially suitable for cystatin-C was 2.8%. The estimated initial cost is ?67.5 (L57.2) million with annual costs of ?2.7 (L2.3) million for the United Kingdom. CONCLUSIONS: The mean eGFR was lower with the CKD-EPI formula and individuals were more likely to be reclassified to more advanced CKD. This may be related to the higher mean age of this unselected population compared to previous studies. Refinements of eGFR formulae, CKD definitions and cystatin-C eligibility in unselected populations are required. PMID- 29566374 TI - Screening for Dysphagia: Perspectives and Practices of Speech and Language Therapists in the Republic of Ireland. AB - OBJECTIVE: Clinical guidelines place considerable emphasis on early swallow screening, as it has significant impact on patient outcomes. This study aims to examine perspectives and practices of speech and language therapists (SLTs) in the Republic of Ireland on swallow screening, exploring challenges in screening methods to improve practice and facilitate research. METHODS: An 18-item web based survey was devised targeting SLTs working in dysphagia in Republic of Ireland. Perspectives were sought on definitions of screening, models of practice, tests used, and factors influencing decision-making. RESULTS: Fifty eight SLTs responded, representing a cross section of clinical settings, populations, and experience. Screening tests most frequently employed were personal screening tests (80%). Important considerations reported in test selection were patient safety (100%), ease of use (97%), staffing (97.5%), and diagnostic accuracy (97.5%). Perceived challenges were staff training associated with screening. CONCLUSIONS: It is concerning that while diagnostic accuracy was recognised as important, most respondents used tests lacking in diagnostic accuracy. While the survey response rate was low, it is hypothesised that findings reflect practice. There is a need for SLTs to equip themselves with the skills to discern which screening test is most diagnostically accurate for clinical populations with further research to improve practice. PMID- 29566375 TI - Long-Term Results of Vitrectomy for Macular Holes after Failure of Vitreolysis. AB - PURPOSE: Ocriplasmin injection may close some small-to-medium macular holes associated with vitreoretinal traction. If the treatment fails, does vitrectomy and gas injection yield the same results as primary surgery? MATERIAL AND METHODS: We report a retrospective case series study of 3 eyes of 3 consecutive patients operated on a few months after initial intravitreal injection of ocriplasmin and enlargement of the macular hole. The minimal follow-up period after surgery was 18 months. RESULTS: Surgery was uneventful in all cases. Vitrectomy, internal limiting membrane peeling, and gas injection allowed closing of the 3 macular holes with a progressive improvement in visual acuity over time. Before ocriplasmin injection, visual acuity ranged from 20/60 to 20/32, after failed ocriplasmin injection from 20/80 to 20/40, and at the final follow-up after 18 months from 20/32 to 20/25. CONCLUSION: Vitrectomy with internal limiting membrane peeling leads to closure of macular holes even in cases of prior failure to close them by ocriplasmin injection. PMID- 29566376 TI - Neurosyphilis with Bilateral Optic Perineuritis in an Immunocompetent Patient. PMID- 29566377 TI - The Primitive Palmomental Reflex in Amyotrophic Lateral Sclerosis. AB - BACKGROUND AND PURPOSE: The palmomental reflex (PMR) is a primitive reflex that might be released due to inhibition in adulthood. It has been associated with several neurodegenerative conditions. The aim of the present study was to evaluate the frequency of PMR in amyotrophic lateral sclerosis (ALS). PATIENTS AND METHODS: Non-demented ALS patients (n = 179) were recruited. Two groups of disease controls were enrolled: (a) non-demented patients with other neurological disorders (NC; n = 86, mean age 60 +/- 14 years); (b) healthy subjects, healthy controls (HC; n = 175, mean age 61 +/- 12 years). PMR was elicited by a brisk stroke along the thenar eminence of the right hand with a key or a pen. RESULTS: The PMR could be elicited in 46% of the ALS patients, compared to 29% of NC and 16% of HC (p < 0.001). A multivariate analysis showed that bulbar-onset and female gender are associated with an increased risk of PMR. CONCLUSION: We demonstrate a higher frequency of the PMR in ALS patients compared to NC or HC. Its expression increases with age, being higher in bulbar-onset patients. Given that the reflex circuit is located in the brain stem, its release due to inhibition might be associated to the presence of a cortico-bulbar tract dysfunction in ALS. PMID- 29566378 TI - Adrenal Insufficiency, Sex Reversal, and Angelman Syndrome due to Uniparental Disomy Unmasking a Mutation in CYP11A1. AB - BACKGROUND/AIMS: Cholesterol side-chain cleavage enzyme (P450scc) deficiency is a rare genetic disorder causing primary adrenal insufficiency with or without a 46,XY disorder of sexual development (DSD). Herein, we report a case of the combination of primary adrenal insufficiency, a DSD (testes with female external genitalia in a setting of a 47,XXY karyotype), and Angelman syndrome. METHODS: Comprehensive genetic analyses were performed, including a single nucleotide polymorphism microarray and whole-exome sequencing. In vitro studies were performed to evaluate the pathogenicity of the novel mutation that was identified by whole-exome sequencing. RESULTS: The patient was found to have segmental uniparental disomy (UPD) of chromosome 15 explaining her diagnosis of Angelman syndrome. Whole-exome sequencing further revealed a novel homozygous intronic variant in CYP11A1, the gene encoding P450scc, found within the region of UPD. In vitro studies confirmed that this variant led to decreased efficiency of CYP11A1 splicing. CONCLUSION: We report the first case of the combination of 2 rare genetic disorders, Angelman syndrome, and P450scc deficiency. After 20 years of diagnostic efforts, significant advances in genetic diagnostic technology allowed us to determine that these 2 disorders originate from a unified genetic etiology, segmental UPD unmasking a novel recessive mutation in CYP11A1. PMID- 29566379 TI - Apabetalone Mediated Epigenetic Modulation is Associated with Favorable Kidney Function and Alkaline Phosphatase Profile in Patients with Chronic Kidney Disease. AB - BACKGROUND/AIMS: The association between serum alkaline phosphatase (ALP) with adverse cardiovascular outcomes, in Chronic Kidney Disease (CKD) patients has previously been reported and may be a result of increased vascular calcification and inflammation. Here we report, for the first time, the effects of pharmacologic epigenetic modulation on levels of ALP and kidney function via a novel oral small molecule BET inhibitor, apabetalone, in CKD patients. METHODS: A post-hoc analysis evaluated patients with estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2, who participated in the apabetalone phase 2 randomized controlled trials (SUSTAIN and ASSURE). 48 CKD subjects with a history of cardiovascular disease (CVD) were treated with 100mg twice-daily of 24 and 26 weeks of apabetalone or placebo. ALP and eGFR were measured prior to randomization and at final visits. RESULTS: Patients who received apabetalone (n=35) versus placebo (n=13) over 6 months showed significantly (p=0.02) lowered serum ALP -14.0% (p<0.0001 versus baseline) versus -6.3% (p=0.9 versus baseline). The eGFR in the apabetalone group increased by 3.4% (1.7 mL/min/1.73 m2) (p=0.04 versus baseline) and decreased by 5.8% (2.9 mL/min/1.73 m2) (p=0.6 versus baseline) in the placebo group. Apabetalone was well tolerated. CONCLUSION: A post-hoc analysis of CKD subjects from the SUSTAIN and ASSURE randomized controlled trials demonstrated favorable effects of apabetalone on ALP and eGFR, and generated the hypothesis that epigenetic modulation by BET inhibition may potentially offer a novel therapeutic strategy to treat CVD and progressive kidney function loss in CKD patients. This is being examined in the phase III trial BETonMACE. PMID- 29566380 TI - Resting Heart Rate Is Not Associated with Cognitive Function. AB - AIMS: In order to examine the hypothesis that elevated resting heart rate (RHR) is associated with impaired cognitive score, we investigated the relationship between RHR and cognitive score in middle-aged, elderly and old Danish subjects from the general population. METHODS: Composite cognitive scores derived from the result of 5 age-sensitive cognitive tests for a total of 7,002 individuals (Middle-aged Danish twin: n = 4,132, elderly Danish twins: n = 2,104 and Danish nonagenarian: n = 766) divided according to RHR and compared using linear regression models adjusted for sex, age, previous heart conditions and hypertension. RHR was assessed by palpating radial pulse. Genetic and shared environmental confounding was addressed in intrapair analyses of 2,049 twin pairs. RESULTS: In unadjusted multivariate models and in multivariable models adjusting for age, sex, heart conditions and hypertension, RHR was not associated with cognitive function. Furthermore, the intrapair analyses showed that RHR was not associated with cognitive score testing within twin pairs, as measured by the proportion of twin pairs in which the twin with higher RHR also was the twin with the lowest composite cognitive score (1,049 pairs of 2,049 pairs [51% (95% CI 49 53), p < 0.289]). CONCLUSION: While elevated RHR has been shown to be associated with adverse health events and poor fitness level, RHR has no relation to cognitive function in the general population. PMID- 29566381 TI - The Research Cycle: Improving Care and Outcomes for Newborn Infants. AB - Ensuring that policies and practice in perinatal care are informed by evidence from high-quality research is fundamental to improving outcomes for newborn infants and their families. Effective interventions in the perinatal period can have a life-long impact disproportionate to their costs. Many of the major advances in care that have transformed outcomes for preterm and sick newborn infants have been informed by empirical and applied health research. Conversely, there are examples of life-long adverse consequences for infants and families that are a legacy of practices based on poor-quality evidence. The challenge in the 21st century is to maintain the trajectory of improvements in care and outcomes. This will most likely be achieved via marginal gains from new or improved care practices underpinned by a range of research approaches, from preclinical and laboratory-based empirical studies that uncover pathogenic pathways or therapeutic mechanisms, to large-scale, applied research such as multicentre, randomised controlled trials. This will involve the coordination and collaboration of research efforts globally. Strategies to develop and prioritise research questions need to involve parents and families. Given the context in which much perinatal research is conducted, particularly in emergency situations around the time of birth, robust and transparent ethics and governance frameworks are essential to maintain the trust and engagement of communities. An ethical imperative exists to ensure that research output is disseminated effectively, and that effective and cost-effective interventions are implemented and integrated within a cycle that audits and benchmarks good practice and outcomes, and informs research evidence-based continuous quality improvement. This is the first in a series of articles on research methodology in neonatal medicine to be published in Neonatology, in response to a request from trainee researchers. We introduce the series by describing the research cycle, in particular how it is applied in neonatal medicine. Subsequent articles will cover translational research, clinical trials, diagnostic tests, global challenges, and the ethical issues relating to neonatal/perinatal research. PMID- 29566382 TI - Testosterone Deprivation Aggravates Left-Ventricular Dysfunction in Male Obese Insulin-Resistant Rats via Impairing Cardiac Mitochondrial Function and Dynamics Proteins. AB - BACKGROUND: We have previously reported that testosterone deprivation at a very young age accelerated, but did not aggravate, left-ventricular (LV) dysfunction in obese insulin-resistant rats. However, the effects of testosterone deprivation during adulthood on LV function in obese insulin-resistant rats remains unclear. We hypothesized that testosterone deprivation aggravates LV dysfunction and cardiac autonomic imbalance via the impairment of cardiac mitochondrial function and dynamics proteins, a reduction in insulin receptor function, and an increase in apoptosis in obese insulin-resistant rats. METHODS: Male rats were fed on either a normal diet (ND) or a high-fat diet (HFD) for 12 weeks. They were then subdivided into 2 groups: sham operation (NDS, HFS) and orchiectomy (NDO, HFO). Metabolic parameters, blood pressure, heart rate variability (HRV), and LV function were determined at baseline and before and after orchiectomy. Mitochondrial function and dynamics proteins, insulin signaling, and apoptosis were determined 12 weeks postoperatively. RESULTS: HFS rats exhibited obese insulin resistance, depressed HRV, and LV dysfunction. In HFO rats, systolic blood pressure was increased with more excessive depression of HRV and increased LV dysfunction, compared with HFS rats. These adverse cardiac effects were consistent with markedly increased mitochondrial dysfunction, reduced mitochondrial complex I and III proteins, reduced mitochondrial fusion proteins, and increased apoptosis, compared with HFS rats. However, testosterone deprivation did not lead to any alteration in the insulin-resistant condition in HFO rats, compared with HFS rats. CONCLUSION: We concluded that testosterone deprivation during adulthood aggravated the impairment of mitochondrial function, mitochondrial respiratory complex, mitochondrial dynamics proteins, and apoptosis, leading to LV dysfunction in obese insulin-resistant rats. PMID- 29566383 TI - Gastritis Can Cause and Trigger Chronic Spontaneous Urticaria Independent of the Presence of Helicobacter pylori. AB - BACKGROUND/AIM: In chronic spontaneous urticaria (CSU), Helicobacter pylori (HP) has been discussed as a cause, but it is unknown whether the bacterium itself or concomitant inflammation is causing the urticaria. Our aim was to investigate HP and upper gastrointestinal lesions as signs of inflammation independently of each other in the pathogenesis of CSU. METHODS: A total of 36 prospectively enrolled CSU patients from Moscow were investigated by gastroscopy and screened for the presence of HP and/or upper gastrointestinal lesions. Those having a positive result were treated according to the Maastricht III recommended guidelines for eradication therapy, and success was assessed by a follow-up gastroscopy. Simultaneously, the activity of CSU was measured before and after therapy of the gastrointestinal condition. RESULTS: HP was observed in 26 of the 36 patients. Erosions or ulcers were found in 18 of the 36 patients, 14 of whom were also positively tested for HP. There was a significant difference in improvement of urticarial symptoms between those who succeeded in healing the erosions and those who did not succeed (p < 0.01) independent of the presence of HP. No significant difference in symptom relief was observed between those who had successful eradication and those in whom HP eradication failed. CONCLUSIONS: Upper gastrointestinal inflammatory disorders can cause CSU and trigger exacerbations independently of HP. This might imply that also in HP-positive patients, urticaria is not based on an immunological reaction against the germ but rather on the underlying inflammation. These findings also strengthen the importance of a gastroenterological workup of patients with CSU. PMID- 29566384 TI - Parkinson's Disease, Melanoma, and Keratinocyte Carcinoma: A Population-Based Study. AB - BACKGROUND: The association between Parkinson's disease (PD) and melanoma is well recognized, but its relationship with non-melanoma skin cancers has not been studied in depth. OBJECTIVE: To assess the relationship between PD, and risk of melanoma and keratinocyte carcinoma: squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). METHODS: This historical cohort study used the data of 1.2 million adult members of a large health organization between 2000 and 2015. Individuals who were diagnosed with PD anytime between 2000 and 2010 were retrospectively followed until 8/2016 for incidence of SCC, BCC, or melanoma identified from physician diagnoses and pathology reports. RESULTS: The PD cohort included 7,727 patients (mean [SD] age = 69.9 [14.8 years]) among the 1,251,695 study population. During follow-up, a total of 4,553, 32,069, and 4,015 cases of BCC, SCC, and melanoma were identified in the study population respectively. Multivariable models revealed that older age, male sex, never smoking, and residence in southern Israel and actinic keratosis were associated with an increased risk of both BCC and SCC. PD patients in the age range 45-64 and 65-84 years at baseline had an OR of 2.11 (95% CI 1.40-3.18) and 1.52 (95% CI 1.21 1.91) for BCC respectively. Weak or no associations were calculated for melanoma or SCC. CONCLUSIONS: We report a positive relationship between PD and risk of BCC. These results should stimulate greater awareness on the part of healthcare providers to the increased risk of BCC in PD patients. PMID- 29566385 TI - A Comprehensive Assessment of the Role of miRNAs as Biomarkers in Gastroenteropancreatic Neuroendocrine Tumors. AB - BACKGROUND/AIMS: A key issue in neuroendocrine neoplasia management is the identification of blood signatures that specifically define the activity of a cancer or local tumor microenvironment. MicroRNAs (miRNAs) may represent such a candidate. To evaluate their clinical utility as biomarkers in gastroenteropancreatic neuroendocrine tumors (GEP-NETs), we assessed their expression in tissue and blood. METHODS: A systematic review of PubMed was undertaken to identify studies investigating miRNAs in GEP-NETs and their utility as blood or tissue biomarkers. RESULTS: Twenty-two studies using a range of methodologies with different normalization protocols were identified: tumor - gastric NET type 1 (n = 1 study: MiR-222, regulates p27KIP1), pancreatic (n = 6: MiR-21 [inflammatory marker, oncogene] and MiR-144 [PI3K/AKT signaling], both up- and downregulated depending on the method), small intestinal (n = 7: no consistent signature), and colorectal (n = 3: no consistent signature); blood - gastric NET type 1 (n = 1: MiR-222), pancreatic (n = 3: MiR-21), and small intestinal (n = 3: no consistent signature). The studies all included heterogeneous cohorts, were insufficiently powered, and utilized different methodologies, and age- and gender-matched controls were not used. Different miRNA isolation methods and detection protocols resulted in inconsistent expression comparing tumor and blood. A scientific discrepancy was the downregulated expression of some circulating candidates compared to tissue levels, suggesting methodological issues or physiological responses to the tumor. Both are of concern in defining the biometrics of a marker. CONCLUSIONS: A potential biomarker for GEP-NETs included MiR-21 (small bowel and pancreas), but this epithelial tumor marker requires prospective validation. Overall, significant scientific investigation remains to identify and demonstrate neuroendocrine specificity and to validate candidate miRNA biomarkers. PMID- 29566386 TI - Occipital Condyle Fracture Extending to the Inferior Part of the Clivus. AB - Although rarely reported in the literature, serious occipital and condylar fractures have been diagnosed more often with the widespread use of computed cranial tomography in traumas. In this paper, a 16-year-old female with a left occipital fracture extending from the left occipital condyle anterior of the hypoglossal canal to the inferior part of the clivus is presented. The fracture which had caused a neurological deficit was cured with conservative treatment. For delayed hypoglossal nerve paralysis due to swelling within the canal, methylprednisolone was started, and a complete cure was attained in about 10 days. Traumatic damage of bony structures of the condyle and clivus at the junction of many vital nerves, vessels, and ligaments may lead to traumatic deficit and death. PMID- 29566387 TI - Spectral-Domain Optical Coherence Tomography-Driven Treat-and-Extend and Pro Re Nata Regimen in Patients with Macular Oedema due to Retinal Vein Occlusion: 24 Month Evaluation and Outcome Predictors. AB - PURPOSE: To analyse the efficacy and outcome predictors of ranibizumab using a spectral-domain optical coherence tomography (SD-OCT)-driven treat-and-extend regimen (TER) versus SD-OCT-driven pro re nata regimen (PRN) in patients with cystoid macular oedema (CME) due to branch or central retinal vein occlusion (BRVO, CRVO). METHODS: Retrospective, consecutive case series. Evaluation included best corrected visual acuity (BCVA), morphological parameters on SD-OCT, and treatment frequency. RESULTS: From baseline to months 12, 18, and 24, BCVA improved by 16.6 +/- 13.1, 15.5 +/- 14.4, and 16.6 +/- 15.8 letters, respectively, in TER (n = 45), compared to 11.3 +/- 17.0, 11.0 +/- 15.0, and 10 +/- 20.5 letters in PRN (n = 31) (p = 0.152, p = 0.237, p = 0.172). The mean reduction in central retinal thickness was -261 +/- 189, -272 +/- 188, and -264 +/- 158 MUm, respectively, in TER, compared to -130 +/- 196, -140 +/- 210, and 166 +/- 207 MUm in PRN (p = 0.006, p = 0.017, p = 0.064). 59% (53%) of TER and 22% (17%) of PRN patients showed no intra- or subretinal fluid on SD-OCT at 12 (24) months. Using TER, the maximum recurrence-free treatment interval increased from 8.9 +/- 2.3 weeks at 12 months to 9.8 +/- 2.3 and 10.5 +/- 2.7 weeks at 18 and 24 months, respectively. The number of injections was significantly higher in the TER than in the PRN group. CONCLUSIONS: In CME, due to BRVO/CRVO, TER provides better morphological outcome using more injections than PRN. PMID- 29566388 TI - Punicalagin and (-)-Epigallocatechin-3-Gallate Rescue Cell Viability and Attenuate Inflammatory Responses of Human Epidermal Keratinocytes Exposed to Airborne Particulate Matter PM10. AB - BACKGROUND/AIMS: Airborne particulate matter with a diameter of < 10 um (PM10) causes oxidative damage, inflammation, and premature skin aging. In this study, we evaluated whether polyphenolic antioxidants attenuate the inflammatory responses of PM10-exposed keratinocytes. METHODS: Primary human epidermal keratinocytes were exposed in vitro to PM10 in the absence or presence of punicalagin and (-)-epigallocatechin-3-gallate (EGCG), which are the major polyphenolic antioxidants found in pomegranate and green tea, respectively. Assays were performed to determine cell viability, production of reactive oxygen species (ROS), and expression of NADPH oxidases (NOX), proinflammatory cytokines, and matrix metalloproteinase (MMP)-1. RESULTS: PM10 decreased cell viability and increased ROS production in a dose-dependent manner. It also increased the expression levels of NOX-1, NOX-2, tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, IL-6, IL-8, and MMP-1. Punicalagin was not cytotoxic up to 300 MUM, and (-)-EGCG was cytotoxic above 30 MUM, respectively. Further, punicalagin (3-30 MUM) and EGCG (3-10 MUM) rescued the viability of PM10-exposed cells. They also attenuated ROS production and the expression of NOX-1, NOX-2, TNF-alpha, IL-1beta, IL-6, IL-8, and MMP-1 stimulated by PM10. CONCLUSIONS: This study demonstrates that polyphenolic antioxidants, such as punicalagin and (-) EGCG, rescue keratinocyte viability and attenuate the inflammatory responses of these cells due to airborne particles. PMID- 29566389 TI - Amyloid Deposits and Idiopathic Normal-Pressure Hydrocephalus: An 18F-Florbetaben Study. AB - BACKGROUND: The first aim of our study was to determine whether cortical 18F florbetaben retention was different between healthy controls and idiopathic normal-pressure hydrocephalus (INPH) patients. Our second aim was to investigate whether there were any relationships between 18F-florbetaben retention and either hippocampal volume or clinical symptoms in INPH patients. METHODS: Seventeen patients diagnosed with INPH and 8 healthy controls underwent studies with magnetic resonance imaging and 18F-florbetaben positron emission tomography imaging. RESULTS: Automated region-of-interest analysis showed significant increases in 18F-florbetaben uptake in several brain regions in INPH patients compared to control subjects, with especially remarkable increases in the frontal (bilateral), parietal (bilateral), and occipital (bilateral) cortices. In the INPH group, right hippocampal volume was found to be negatively correlated with right frontal 18F-florbetaben retention. Korean-Mini Mental State Examination scores negatively correlated with right occipital 18F-florbetaben retention. Higher 18F-florbetaben retention correlated significantly with a higher Clinical Dementia Rating Scale score in the right occipital cortex. CONCLUSIONS: Our results indicate that INPH might be a disease exhibiting a characteristic pattern of cortical 18F-florbetaben retention. 18F-florbetaben retention in the frontal cortex may be related to hippocampal neuronal degeneration. Our findings may also help us understand the potential pathophysiology of cognitive impairments associated with INPH.

AB - BACKGROUND: Although difficulties in emotion regulation (ER) are considered a core feature of borderline personality disorder (BPD), the specific strategies that individuals with BPD most commonly use, their diagnostic specificity, and their associations with harmful behaviors have not been firmly established. SAMPLING AND METHODS: Individuals with BPD (n = 30), mixed anxiety and/or depressive disorders (MAD; n = 30), and healthy controls (HC; n = 32) completed questionnaires assessing both cognitive ER strategies (e.g., cognitive reappraisal) and potentially harmful behaviors that individuals might use to regulate their emotions (e.g., self-injury). RESULTS: BPD subjects endorsed more maladaptive cognitive ER strategies and fewer adaptive strategies compared to HC. Compared to MAD subjects, BPD individuals endorsed more maladaptive cognitive ER strategies, but only when those with subthreshold symptoms in the MAD group were excluded. BPD also endorsed engaging in potentially harmful behaviors more often than both HC and MAD. Discriminant analysis revealed that MAD endorsed lower rates of problem-solving and cognitive reappraisal compared to both HC and BPD. Higher maladaptive and lower adaptive ER strategies were associated with higher rates of potentially harmful behaviors, although the specific strategies differed for MAD versus BPD. CONCLUSIONS: BPD and MAD endorse cognitive ER strategies with a comparable frequency, although BPD subjects engage in potentially harmful behaviors more often. Subthreshold BPD symptoms may also affect rates of ER strategy use in individuals with other mental disorders. PMID- 29566391 TI - Psychopathological Symptoms and Satisfaction with Mental Health in Patients with Schizophrenia. AB - BACKGROUND: The patient's view of their mental health is a central aspect in research and practice. Yet, little is known about which psychopathological symptoms are linked with patients' satisfaction with their mental health. We aimed to identify these symptoms in patients with schizophrenia. METHODS: An individual patient data meta-analysis was conducted with data from 2,488 patients from 8 independent studies. Satisfaction with mental health was rated on a 7 point scale, and symptoms were observer-rated using identical items from the Brief Psychiatric Rating Scale and the Positive and Negative Symptom Scale. Mixed multilevel univariate followed by multivariate regression models were used to identify symptoms associated with satisfaction with mental health. RESULTS: In univariate regressions, all subscales - not age and gender - were associated with mental health satisfaction. In the multivariate regression, only affective and negative symptoms were significantly associated with a lower satisfaction with mental health, explaining 22.5% of the variance. CONCLUSIONS: Observer-rated psychopathological symptoms are linked to patients' mental health satisfaction. In addition to affective symptoms - which are commonly negatively linked with satisfaction ratings - a higher level of negative symptoms makes patients less satisfied with their mental health, whilst positive and other symptoms do not influence mental health satisfaction. PMID- 29566392 TI - Dual p16 and Ki-67 Expression in Liquid-Based Cervical Cytological Samples Compared to Pap Cytology Findings, Biopsies, and HPV Testing in Cervical Cancer Screening: A Diagnostic Accuracy Study. AB - OBJECTIVE: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the "dual" assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection. STUDY DESIGN: Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for the "dual immunocytochemistry assay" were calculated and compared to histopathological results and to high-risk HPV DNA detection in adult women or teenagers submitted to cervical cancer screening. RESULTS: A total of 151 women were included. The majority (96.2%) of those with negative dual assay results had lower biopsy grades (p < 0.001). Women with cytology results suggestive of cervical cancer had positive dual immunocytochemistry assay results more frequently (p < 0.001), and these positive results were also significantly associated with biopsy findings (p < 0.001) and with high-risk genotype HPV infection (p = 0.007). Specificity and PPV for the dual assay were 0.972 (0.855 0.999) and 0.800 (0.284-0.995), respectively, and 1.000 (0.590-1.000) and 1.000 (0.631-1.000) for HPV detection. CONCLUSIONS: The dual immunocytochemistry assay had high specificity and PPV. It reveals a persistent HPV infection, avoiding the need for new tissue collections for biopsies or hybrid capture. PMID- 29566393 TI - The Influence of Cognitive Bias on Caries Lesion Detection in Preschool Children. AB - We aimed to evaluate whether children's caries experience exerts an influence on the performance of visual and radiographic methods in detecting nonevident proximal caries lesions in primary molars. Eighty children (3-6 years old) were selected and classified as having a lower (<=3 decayed, missing, or filled surfaces; dmf-s) or higher (> 3 dmf-s) caries experience. Two calibrated examiners then assessed 526 proximal surfaces for caries lesions using visual and radiographic methods. As a reference standard, 2 other examiners checked the surfaces after temporary separation. Noncavitated and cavitated lesion thresholds were considered and Poisson multilevel regression analyses were conducted to evaluate the influence of caries experience on the performance of diagnostic strategies. Accuracy parameters stratified by caries experience were also derived. A statistically significant influence of caries experience was observed only for visual inspection, with more false-positive results in children with a higher caries experience at the noncavitated lesion threshold, and more false results at the cavitated threshold. The detection of noncavitated caries lesions in children with a higher caries experience was overestimated (specificity = 0.696), compared to children with a lower caries experience (specificity = 0.918), probably due to confirmation bias. However, the examiners underestimated the detection of cavitated lesions in children with a higher caries experience (sensitivity = 0.143) compared to lower-caries-experience children (sensitivity = 0.222), possibly because of representativeness bias. The radiographic method was not influenced by children's caries experience. In conclusion, children's caries experience influences the performance of visual inspection in detecting proximal caries lesions in primary teeth, evidencing the occurrence of cognitive biases. PMID- 29566394 TI - A Randomized Controlled Trial in Routine Clinical Practice Comparing Acceptance and Commitment Therapy with Cognitive Behavioral Therapy for the Treatment of Major Depressive Disorder. AB - BACKGROUND: Since current therapies for depression are effective but not for all patients alike, we need to further improve available treatments. Existing research suggests that acceptance and commitment therapy (ACT) may effectively treat major depressive disorder (MDD). We compared ACT with cognitive behavioral therapy (CBT) for depression, testing the hypothesis that CBT would outperform ACT. METHODS: We conducted a randomized controlled trial with 82 patients suffering from MDD. Data were collected before and after treatment and at the 6 month follow-up, assessing diagnosis, symptom levels of depression, and quality of life. RESULTS: After treatment, the rates of remission from depression were 75 and 80% for the ACT and CBT conditions, respectively. Patients in both conditions further reported significant and large reductions in depressive symptoms and improvement in quality of life from before to after treatment as well as at the follow-up. Our findings indicated no significant differences between the two intervention groups. CONCLUSION: Our results indicate that CBT is not more effective in treating depression than ACT. Further research is needed to investigate whether ACT and CBT work differently for different groups of patients with depression. PMID- 29566395 TI - Angiographic and Tomographic Prognostic Factors of Chronic Central Serous Chorioretinopathy Treated with Half-Dose Photodynamic Therapy. AB - AIMS: To identify the angiographic and tomographic prognostic factors of chronic central serous chorioretinopathy (CSC) treated with half-dose photodynamic therapy (PDT). METHODS: This is a consecutive series of 61 eyes with chronic CSC treated with half-dose PDT from January 1, 2009 to October 31, 2016. RESULTS: The mean logMAR best-corrected visual acuity (BCVA) improved from 0.47 to 0.31 at 3 months (p < 0.001). From multivariate regression, the final BCVA was significantly associated with the baseline BCVA (p = 0.003), a diffuse hyperfluorescence pattern on indocyanine green angiography (ICGA) (p = 0.024), posttreatment shallow irregular pigment epithelium detachment (PED) (p = 0.022), and disruption of the ellipsoid zone (p = 0.007). A diffuse hyperfluorescence pattern on ICGA was associated with a 77.4 times risk of subretinal fluid persistence after treatment (p = 0.009). CONCLUSION: A poor baseline BCVA, diffuse hyperfluorescence ICGA pattern, shallow irregular PED, and disruption of the ellipsoid zone indicate poor prognosis.

AB - BACKGROUND: We sought to determine the leading causes of cardiovascular (CV) hospitalization, and to describe and compare national rates of CV hospitalization by age, gender, race, ethnicity, region, and year, among U.S. veterans. METHODS: We evaluated the electronic health records of all veterans aged >=18 years who had accessed any healthcare services at either a VA healthcare facility or a non VA healthcare facility that was reimbursed by the VA, between January 1 2010 and December 31 2014. Among these 8,452,912 patients, we identified the 5 leading causes of CV hospitalization and compared rates of hospitalization by age, gender, race, ethnicity, region, year and type of VA healthcare user. RESULTS: The top 5 causes of CV hospitalization were: coronary atherosclerosis, heart failure, acute myocardial infarction, stroke and atrial fibrillation. Overall, 297,373 (3.5%) veterans were hospitalized for one or more of these cardiovascular conditions. The percentage of veterans hospitalized for one or more of these CV conditions decreased over time, from 1.23% in 2010 to 1.18% in 2013, followed by a slight increase to 1.20% in 2014. There was significant variation in rates of CV hospitalization by gender, race, ethnicity, geographic region, and urban vs. rural zip code. In particular, older, male, Black, non-Hispanic, urban and Continental region veterans experienced the highest rates of CV hospitalizations. CONCLUSIONS: Among 8.5 million patients enrolled in the VA healthcare system from 2010 to 2014, there was substantial variation in rates of CV hospitalization by age, gender, race, geographical distribution, year, and use of non-VA (vs. VA only) healthcare care facilities.

PMID- 29566403 TI - A Theoretical Approach to Selection of a Biologically Active Substance in Ultra Low Doses for Effective Action on a Biological System. AB - BACKGROUND AND AIM: An approach is offered to selecting a biologically active substance (BAS) in ultra-low dose for effective action on a biological system (BS). The technique is based on the assumption that BAS in ultra-low doses exerts action on BS by means of spin supercurrent emerging between the spin structure created by BAS, on the one hand, and the spin structure created by BS, on the other hand. According to modern quantum-mechanical concepts, these spin structures may be virtual particles pairs having precessing spin (that is, be essentially spin vortices in the physical vacuum) and created by the quantum entities that BAS and BS consist of. The action is effective provided there is equality of precession frequencies of spins in these spin structures. METHOD: In this work, some methods are considered for determining the precession frequencies of spins in virtual particles pairs: (1) determination of energy levels of quantum entities that BS and BAS consist of; (2) the use of spin-flip effect of the virtual particles pair spin, the effect being initiated by action of magnetic vector potential (the spin-flip effect takes place when the varied frequency of the magnetic vector potential equals the precession frequency of the spin); (3) determining the frequencies of photons effectively acting on BS. RESULTS AND CONCLUSION: It is shown that the effect of BAS in ultra-low doses on BS can be replaced by the effect of a beam of low-intensity photons, if the frequency of photons equals the precession frequency of spin in spin structures created by BS. Consequently, the color of bodies placed near a biological system is able to exert an effective action on the biological system: that is "color therapy" is possible. It is also supposed that the spin-flip effect may be used not only for determining the precession frequency of spin in spin structures created by BS but also for therapeutic action on biological systems. PMID- 29566402 TI - Significance of BRAF V600E Mutation and Cytomorphological Features for the Optimization of Papillary Thyroid Cancer Diagnostics in Cytologically Indeterminate Thyroid Nodules. AB - BACKGROUND: Ultrasound guided fine needle aspiration biopsy with cytologic analysis is an initial step in diagnostic of thyroid nodules. Unfortunately, up to 30% of biopsies are indeterminate and diagnostic surgery is required. The aim of this study was to estimate the diagnostic value of BRAF V600E mutation status combined with cytomorphological features for diagnosis of papillary thyroid cancer (PTC) in cytologically indeterminate thyroid nodules. METHODS: A prospective study analyzed patients who had ultrasound suspicious thyroid nodules, underwent fine needle aspiration and cytological examination, and were classified according to the Bethesda system. Patients from indeterminate diagnostic categories were examined for BRAF V600E mutation and 22 cytomorphological features, and underwent thyroid surgery. A binary logistic regression model was used to evaluate the diagnostic utility. RESULTS: A total of 219 patients met study criteria. After histological examination, 77 (35.2%) patients were diagnosed with PTC and 142 (64.8%) with benign nodular thyroid disease. According to logistic regression model, significant features for PTC diagnosis were: liquid colloid consistency, papillary structures, eosinophilic colloid bodies, and BRAF V600E mutation. Risk groups classified by this model have sensitivity of 80.5% (95% CI: 69.9 to 88.7), specificity of 99.3% (95% CI: 96.1 to 100), positive predictive value of 98.4% (95% CI: 89.8 to 99.8), negative predictive value of 90.4% (95% CI: 85.7 to 93.7), and accuracy of 92.7% (95% CI: 88.4 to 95.8) for PTC diagnosis. CONCLUSIONS: Evaluation of BRAF V600E mutation status combined with cytomorphological features for diagnosis of PTC in cytologically indeterminate thyroid nodules can significantly improve diagnostic accuracy and reduce the number of diagnostic operations (calculator available at www.ptc-calc.we2host.lt). PMID- 29566404 TI - In Vitro Effects of Homeopathic Drugs on Cultured Escherichia coli. AB - BACKGROUND: Recurrent urinary tract infections (UTIs) are one of the most common morbidities in persons with neurogenic lower urinary tract dysfunction (NLUTD). Repetitive antibiotic treatment increases the risk of selecting multi-resistant bacteria. Homeopathic treatment has been reported to be effective in these patients. The mechanism of action, however, has not been clarified. Recently, a direct bactericidal effect of homeopathic remedies was shown. Such an effect is not in accordance with the general principles of homeopathy. To test this paradigm, we assessed the in vitro effects of homeopathic drugs on Escherichia coli derived from patients with NLUTD. METHODS: E. coli bacteria were harvested from 28 consecutive urine cultures. Standard antibiotic resistance testing and simultaneous resistance testing to homeopathic drugs (Apis mellifica, Cantharis, Causticum hahnemanni, Staphysagria, Nux vomica, Berberis vulgaris, and Lycopodiumclavatum) in high (C30) potency were performed. RESULTS: No significant inhibitory effect of any of the tested homeopathic drugs on any E. coli population could be found, irrespective of their sensitivity to antibiotic treatment. CONCLUSION: Based on our results, effects of homeopathic treatment of UTI are not based on direct bactericidal or bacteriostatic effects. These findings are in concordance with the hypothesis that homeopathy is based on host effects: for example, activation of the immune system, rather than effects on pathogens.

PMID- 29566406 TI - Off-Pump Coronary Artery Bypass Grafting and Stroke-Exploratory Analysis of the GOPCABE Trial and Methodological Considerations. AB - BACKGROUND: Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (off-pump CABG) may reduce severe adverse events including stroke. METHODS: In the German Off-Pump Coronary Artery Bypass Grafting in Elderly patients trial, the rate of major adverse cardiovascular events was compared in 2,394 elderly (>= 75 years) patients undergoing CABG with (on-pump) or without (off-pump) cardiopulmonary bypass. This exploratory post-hoc analysis investigated the impact of surgical aortic manipulation on the rate of stroke. RESULTS: There was no significant difference in the rate of stroke within 30 days after surgery between both groups (off-pump: 2.2%; on-pump: 2.7%; odds ratio [OR]: 0.83 [0.5 1.38]; p = 0.47). Within the off-pump group, different degrees of aortic manipulation did not lead to significant different stroke rates (tangential clamping: 2.3%; OR 0.86 [0.46-1.60]; clampless device: 1.8%; OR 0.67 [0.26-1.75]; no aortic manipulation: 2.4%; OR 0.88 [0.37-2.14]). An aggregate analysis including more than 10,000 patients out of the four recent major trials also yielded comparable stroke rates for on- and off-pump CABG (off-pump: 1.4%; on pump: 1.7%; OR 0.87 [0.64-1.20]). CONCLUSION: Within recent prospective randomized multicenter trials off-pump CABG did not result in lower stroke rates. The possible intrinsic benefit of off-pump CABG may be offset by the complexity of the operative therapy as well as the multiple pathomechanisms involved in perioperative stroke. PMID- 29566407 TI - Intracranial Hemorrhage and Early Mortality in Patients Receiving Extracorporeal Membrane Oxygenation for Severe Respiratory Failure. AB - Intracranial hemorrhage (ICH) is a serious complication in patients receiving veno-venous extracorporeal membrane oxygenation (VV-ECMO) and is associated with high mortality. It is unknown whether ICH may be a consequence of the ECMO or of an underlying disease. The authors first aimed to assess the incidence of ICH at initiation and during the course of VV-ECMO and its associated mortality. The second aim was to identify clinical and laboratory measures that could predict the development of ICH in severe respiratory failure. Data were collected from a total number of 165 patients receiving VV-ECMO from January, 2012 to December, 2016 in a single tertiary center and treated according to a single protocol. Only patients who had a brain computed tomography within 24 hours of initiation of ECMO (n = 149) were included for analysis. The prevalence and incidence of ICH at initiation and during the course of VV-ECMO (at median 9 days) were 10.7% (16/149) and 5.2% (7/133), respectively. Thrombocytopenia and reduced creatinine clearance (CrCL) were independently associated with increased risk of ICH on admission; odds ratio (95% confidence interval): 22.6 (2.6-99.5), and 10.8 (5.6 16.2). Only 30-day (not 180-day) mortality was significantly higher in patients with ICH on admission versus those without (37.5% [6/16] vs 16.4% [22/133]; p = 0.03 and 43.7% [7/16] vs 26.3% [35/133]; p = 0.15, respectively). Reduced CrCL and thrombocytopenia were associated with ICH at initiation of VV-ECMO. The higher incidence of ICH at initiation suggests it is more closely related to the severity of the underlying lung injury than to the VV-ECMO itself. ICH at VV-ECMO initiation was associated with early mortality. PMID- 29566408 TI - Surgical Complications after Right Hepatectomy for Live Liver Donation: Largest Single-Center Western World Experience. AB - The authors assessed the incidence, management, and risk factors for postoperative complications after right lobe (RL) live donor hepatectomy in a high-volume center in North America. All donors undergoing an RL live donor hepatectomy between 2000 and 2017 at our institution were included. The primary outcome was the development of complications (both medical and surgical). Predictors of postoperative complications were determined by logistic regression. A total of 587 patients underwent RL live donor hepatectomy. Among those, 187 postoperative complications were diagnosed in 141 (24%) patients. One patient had >90-day morbidity, and there were no donor deaths. Overall complications were significantly higher in the first era, 2000 to 2008 (81 [57.4%]) versus the second era, 2009 to 2017 (60 [42.6%]) (p = 0.01). On multivariate analysis, the only predictor of postoperative complications was the center volume of RL live donor hepatectomy in the previous 12 months with an odds ratio of 0.97 (95% confidence interval: 0.95-0.99). In conclusion, increasing center volume is associated with lower rates of postoperative complications after RL living liver donation.

AB - Five new botryane sesquiterpenes (1: -5: ), one new cyclopentadepsipeptide (9: ), and two new xanthones (11: - 12: ), together with 11 known compounds, were isolated from Trichoderma oligosporum. The structures of the new compounds were identified by comprehensive spectroscopic methods including nuclear magnetic resonance and mass spectrometry. The cytotoxicity of 1: -19: was evaluated against K562, A549, and ASPC cell lines. Compounds 5, 8, 11, 17: , and 18: showed cytotoxicity against the K562 cell line with more than 50% inhibition at 12.5 uM. As to A549 cell line, compound 8: showed the strongest cytotoxicity with approximately 50% inhibition at 25.0 uM. No compounds showed cytotoxicity against the ASPC cell line. PMID- 29566410 TI - Mechanical Allodynia Predicts Better Outcome of Surgical Decompression for Painful Diabetic Peripheral Neuropathy. AB - BACKGROUND: To determine the role of mechanical allodynia (MA) in predicting good surgical outcome for painful diabetic peripheral neuropathy (DPN). MATERIALS AND METHODS: Data of 192 patients with painful DPN were collected in this study, with 148 surgical patients and 44 patients in the control group. Both groups were further divided into subgroups based on the presence of MA on admission. Clinical evaluations including the visual analog scale (VAS), the Hospital Anxiety and Depression Scale (HADS), nerve conduction velocity (NCV), and high-resolution ultrasonography (cross-sectional area, CSA) were performed preoperatively and postoperatively. RESULTS: The levels of VAS and HADS and the results of NCV and CSA were improved in the surgical group (p < 0.05). In the surgical subgroups, pain reduction, psychiatric amelioration, improvement in NCVs, and the restoration of the CSA were observed in patients with signs of MA (p < 0.05), whereas only pain reduction, psychiatric amelioration, and restoration of the CSA were noted in patients without signs of MA (p > 0.05). Furthermore, better pain reduction was achieved in patients with MA when compared with those without MA (p < 0.05). CONCLUSIONS: MA is proved to be a reliable predictor of good surgical outcome for painful DPN. PMID- 29566411 TI - Surgery of Neonates: What's New in Dealing with Perioperative Complications? PMID- 29566412 TI - The Evolution of Antithrombotic Care in Cardiovascular Patients. PMID- 29566413 TI - Rivaroxaban: A New Treatment Paradigm in the Setting of Vascular Protection? AB - The pathophysiology of atherosclerosis involves a diseased endothelium, lipid accumulation and low-grade inflammation. In later stages of coronary artery disease (CAD) and peripheral arterial disease (PAD), plaque rupture may induce atherothrombosis caused by fibrin formation and platelet activation, leading to vessel occlusion with subsequent organ damage such as myocardial infarction, stroke or limb ischaemia. Because of the high disease burden associated with CAD and PAD, there is a need for continuous vascular protection beyond currently available treatments including antiplatelet agents. Due to its central role in the coagulation cascade, inhibition of factor Xa, with the subsequent reduced thrombin formation that impacts not only fibrin but also platelets, may provide additional benefit over using antiplatelets alone. Evidence from Anti-Xa Therapy to Lower Cardiovascular Events in Addition to Standard Therapy in Subjects with Acute Coronary Syndrome-Thrombolysis In Myocardial Infarction-51 (ATLAS-ACS 2 TIMI 51) supports the use of the direct, oral, factor Xa inhibitor rivaroxaban (2.5 mg twice-daily [bid] and 5 mg bid) in reducing mortality and morbidity in patients with acute coronary syndrome, when combined with antiplatelets. Here, we review the role of rivaroxaban in three clinical trials of CAD and/or PAD: Cardiovascular OutcoMes for People using Anticoagulation StrategieS (COMPASS), Vascular Outcomes studY of ASA alonG with rivaroxaban in Endovascular or surgical limb Revascularization for PAD (VOYAGER PAD) and Cardiovascular Outcome Modification, Measurement AND Evaluation of Rivaroxaban in patients with Heart Failure (COMMANDER HF). PMID- 29566414 TI - Understanding the Value of Real-World Evidence: Focus on Stroke Prevention in Atrial Fibrillation with Rivaroxaban. AB - Real-world data are a well-recognized component within the drug lifecycle, and such data are generated from a range of sources and study designs, including claims databases, electronic health records, non-interventional studies (NIS) and registries. While this information can be of vital clinical importance, there may be challenges in understanding the relevance of the differing study designs, endpoints and populations. Here, we summarize the value of real-world evidence and considerations pertinent to their use in clinical research. Owing to the variety of analyses being conducted using real-world data, it is important for researchers and clinicians to have a clear understanding of the nature and origin of those data, and to ensure they are valid, reliable and robust in terms of extrapolating meaningful findings. There are crucial questions to address when evaluating real-world studies, and we introduce a checklist to meet these objectives. In addition to advice for appraising data quality and study designs, several updates will be covered from real-world studies of rivaroxaban for stroke prevention in patients with atrial fibrillation (AF): the nationwide Danish cohort study, U.S. Department of Defense Military Health System database, retrospective claim database study REAFFIRM and a pooled analysis from the global NIS XArelto on preveNtion of sTroke and non-central nervoUS system systemic embolism in patients with non-valvular atrial fibrillation (XANTUS). Real-world studies consistently show that rivaroxaban is an effective treatment option with acceptable safety when used for stroke prevention in a large number of patients with AF across the globe. PMID- 29566415 TI - The Rivaroxaban Program and the Management of Unmet Needs in Thromboembolic Disease. AB - Rivaroxaban is a non-vitamin K antagonist oral anticoagulant that acts as a direct factor Xa inhibitor, and is widely used for the prevention and treatment of thromboembolic disorders. As further knowledge gaps are identified in thrombosis management, the rivaroxaban research program has expanded in an attempt to elucidate the wider benefits of rivaroxaban. An increased understanding of the interactions taking place within the coagulation cascade may support a broader role for rivaroxaban (2.5 mg twice daily [bid] or 5 mg bid) in the setting of vascular protection, either alone or in combination with an antiplatelet agent. The aim of this article is to describe the potential role of rivaroxaban in the context of vascular protection and provide an overview of recently completed and ongoing randomized controlled trials of rivaroxaban in the areas of stroke prevention, venous protection and vascular protection. PMID- 29566416 TI - Beyond Stroke Prevention in Atrial Fibrillation: Exploring Further Unmet Needs with Rivaroxaban. AB - With improved life expectancy and the aging population, the global burden of atrial fibrillation (AF) continues to increase, and with AF comes an estimated fivefold increased risk of ischaemic stroke. Prophylactic anticoagulant therapy is more effective in reducing the risk of ischaemic stroke in AF patients than acetylsalicylic acid or dual-antiplatelet therapy combining ASA with clopidogrel. Non-vitamin K antagonist oral anticoagulants are the standard of care for stroke prevention in patients with non-valvular AF. The optimal anticoagulant strategy to prevent thromboembolism in AF patients who are undergoing percutaneous coronary intervention and stenting, those who have undergone successful transcatheter aortic valve replacement and those with embolic stroke of undetermined source are areas of ongoing research. This article provides an update on three randomized controlled trials of rivaroxaban, a direct, oral factor Xa inhibitor, that are complete or are ongoing, in these unmet areas of stroke prevention: oPen-label, randomized, controlled, multicentre study explorIng twO treatmeNt stratEgiEs of Rivaroxaban and a dose-adjusted oral vitamin K antagonist treatment strategy in patients with Atrial Fibrillation who undergo Percutaneous Coronary Intervention (PIONEER AF-PCI) trial; the New Approach riVaroxaban Inhibition of factor Xa in a Global trial vs Aspirin to prevenT Embolism in Embolic Stroke of Undetermined Source (NAVIGATE ESUS) trial and the Global study comparing a rivAroxaban-based antithrombotic strategy to an antipLatelet-based strategy after transcatheter aortIc vaLve rEplacement to Optimize clinical outcomes (GALILEO) trial. The data from these studies are anticipated to help address continuing challenges for a range of patients at risk of stroke. PMID- 29566417 TI - Treatment Challenges in Venous Thromboembolism: An Appraisal of Rivaroxaban Studies. AB - Venous thromboembolism (VTE) presents a continuing clinical burden to healthcare systems and there are patient groups for whom VTE management is challenging. Depending on the patient profile, the optimal duration of anticoagulation for VTE treatment can be unclear. EINSTEIN CHOICE was a Phase III, randomized, double blind trial that compared the safety and efficacy of two once-daily (od) doses of the direct, oral factor Xa inhibitor rivaroxaban (20 and 10 mg) with acetylsalicylic acid (ASA; 100 mg daily) for prevention of recurrent VTE. Extended therapy with rivaroxaban at either dose was more effective than ASA at preventing recurrent VTE without increasing bleeding risk. Another group that is challenging to treat in the context of VTE is patients with cancer-associated thrombosis. Cancer is associated with a hypercoagulable state, while cancer treatment itself may increase VTE risk. Evidence supporting the use of non vitamin K antagonist oral anticoagulants in patients with cancer is growing through specifically designed studies. Cancer Associated thrombosis-expLoring soLutions for patIentS through Treatment and prevention with rivarOxaban (CALLISTO) is an international research program exploring the role of rivaroxaban for the prevention and treatment of cancer-associated thrombosis. Here, we present overviews of three CALLISTO studies: PRO-LAPS II, CASTA-DIVA and COSIMO. Currently available and anticipated results from studies in a variety of patients at risk of or with VTE will provide valuable insights and seek to optimize future VTE management. PMID- 29566418 TI - Estradiol: A Steroid with Multiple Facets. AB - Seventy-five glorious years have passed since estradiol was discovered by Edward Doisy. From discovery in the ovaries to delineation of diverse physiological effects, research on estrogens has covered a lot of ground. Estrogen receptors that mediate estrogenic effects, have been detected not only in reproductive organs, but also in other body organs. Estrogen receptors function either as conventional transcription factors or as rapid signal transducers. These different modes of action are opted by estrogens to elicit an array of reproductive and non-reproductive functions. It is well established that estrogens promote cell proliferation in various tissues and hence are also linked to carcinogenesis. Anti-estrogens are being used as adjunct therapies for cancers since several years. On the other hand, estrogen-based strategies are used to alleviate adverse effects of menopause. Apart from estrogens synthesized in various organs, exposure to environmental estrogens can also impact physiology. Thus, too much or too less of estrogens can tip the balance and lead to unfavorable consequences. Multiple estrogen receptors with their tissue- or cell type-specific expression eliciting dose-dependent effects make it perplexing to 'unify' estrogenic actions in diverse tissues/organs. This warrants more research on estrogen-mediated effects and their regulation in somatic and reproductive tissues. This review presents physiological and pathological aspects of estrogens thus highlighting the good, bad, and ugly facets of estrogens.

AB - The accuracy and usefulness of gastrointestinal ultrasound (GIUS) for detecting activity and complications of inflammatory bowel diseases (IBD), has been reported in studies, promoting this technique as an important tool for the management of IBD patients. Whilst well recognised by international guidelines, standardization and general agreement in the definition of the luminal and extra intestinal features, still need to be well defined.A task force group of 17 experts in GIUS faced this issue, by developing recommendations and clinical guidelines for the use of GIUS in IBD, under the auspices of EFSUMB. This article presents the consensus on the current data on sonographic features of IBD and summarises the accuracy of different sonographic modalities for the management of IBD patients. PMID- 29566420 TI - Evaluation of Inter-System Variability in Liver Stiffness Measurements. AB - AIM: The primary aim of this study was to determine the inter-system variability of liver stiffness measurements (LSMs) in patients with varying degrees of liver stiffness. The secondary aim was to determine the inter-observer variability of measurements. MATERIALS AND METHODS: 21 individuals affected by chronic hepatitis C and 5 healthy individuals were prospectively enrolled. The assessment of LSMs was performed using six ultrasound (US) systems, four of which with point shear wave elastography (p-SWE) and two with 2 D shear wave elastography (2D-SWE) systems. The Fibroscan (Echosens, France) was used as the reference standard. Four observers performed the measurements in pairs (A-B, C-D). The agreement between different observers or methods was calculated using Lin's concordance correlation coefficient. The Bland-Altman limits of agreement (LOA) were calculated as well. RESULTS: There was agreement above 0.80 for all pairs of systems. The mean difference between the values of the systems with 2D-SWE technique was 1.54 kPa, whereas the maximum mean difference between the values of three out of four systems with the pSWE technique was 0.79 kPa. The intra-patient concordance for all systems was 0.89 (95 % CI: 0.83 - 0.94). Inter-observer agreement was 0.96 (95 % CI: 0.94 - 0.98) for the pair of observers A-B and 0.93 (95 % CI: 0.89 - 0.96) for the pair of observers C-D. CONCLUSION: The results of this study show that the agreement between LSMs performed with different US systems is good to excellent and the overall inter-observer agreement in "ideal conditions" is above 0.90 in expert hands. PMID- 29566421 TI - The Role of Virtual Rehabilitation in Total Knee and Hip Arthroplasty. AB - Virtual rehabilitation therapies have been developed to focus on improving care for those suffering from various musculoskeletal disorders. There has been evidence suggesting that real-time virtual rehabilitation may be equivalent to conventional methods for adherence, improvement of function, and relief of pain seen in these conditions. This study specifically evaluated the use of a virtual physical therapy/rehabilitation platform for use during the postoperative period after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The use of this technology has the potential benefits that allow for patient adherence, cost reductions, and coordination of care. PMID- 29566422 TI - Clinical Prospective Study on the Use of Subcutaneous Carboxytherapy in the Treatment of Diabetic Foot Ulcer. AB - Diabetic footfoot ulcer (DFU) is a serious complication of diabetes mellitus, and possibly the major morbidity of the diabetic foot. It is the most common foot injury in diabetic patients and can lead to lower-extremity amputation. Management of DFU requires a systematic knowledge of the major risk factors for amputation, frequent routine evaluation, scrupulous preventive maintenance, and correction of peripheral arterial insufficiency. Carboxytherapy refers to the subcutaneous injection of CO2 to improve the microcirculation and promote wound healing by stimulating the microcirculation. Since optimal ulcer-healing requires adequate tissue perfusion, it is considered that carboxytherapy could be useful in the treatment of DFU. The present prospective clinical study included 40 patients with different sizes and types of chronic DFU. In addition to cleaning of the wound, antibiotics and debridement as necessary, the treatment protocol included blood sugar control, medication, healthy habits, no weight-bearing, and carboxytherapy. The results showed that this treatment that included carboxytherapy promoted wound-healing and prevented amputation. These positive effects should be confirmed through a complete study that includes different clinical and instrumental parameters. PMID- 29566423 TI - A Prospective Clinical and Instrumental Study on the Effects of a Transcutaneous Cosmeceutical Gel that is Claimed to Produce CO2. AB - Carboxytherapy is the therapeutic use of carbon dioxide (CO2) in its gaseous state. Since 1933, carboxytherapy has referred to either the subcutaneous injection of CO2 or percutaneous application in a warm bath. The present clinical study was performed to determine if there were any changes in the dermis after the application of a transcutaneous gel, which is claimed to produce CO2, and, if so, how these changes compared to those with CO2 injection. Ten patients received transcutaneous treatment with the gel on one side of the face and the other side without any product was used as a control. We used videocapillaroscopy with an optic probe (VCSO) to evaluate the changes in the microcirculation of the skin. VCSO was performed for the treated right and untreated left ear lobes in each patient. VCSO was performed before treatment was started (VCSO1) and after 7 days of treatment (VCSO2). A comparison of VCSO1 to VCSO2 showed an increase in the microcirculation, an increase in vertical and horizontal capillaries, and a reduction in the area of ischemia. These results are similar to those observed in other studies with CO2 injection. In conclusion, use of this transcutaneous CO2 gel produced changes in the dermis similar to those observed with subcutaneous injection of CO2. PMID- 29566424 TI - Integration of the nasal complex: Implications for developmental and evolutionary change in modern humans. AB - OBJECTIVES: Assessing the strength of integration among different regions of the modern human nasal complex is important for developing a more thorough understanding of the determinants of nasal morphology. Given the morphogenetic influence of cartilage on adjacent intramembranous growth sites, the interaction between chondrocranial- versus intramembranous-derived nasal structures may have a significant influence on patterns of nasal variation. The purpose of this study is to examine integration between the chondrocranial- and intramembranous-derived regions of the nasal complex. MATERIALS AND METHODS: Using computed tomograph (CT) scans, we collected three-dimensional coordinate landmark data from a static adult sample (n = 62). First, using centroid size, and the symmetric and asymmetric components of shape variation, we examined the strength of integration between landmarks representing chondrocranial-derived structures (e.g., ethmoid, external nasal cartilages) and landmarks representing intramembranous-derived structures (nasal floor, anterior nasal aperture, etc.). Second, given that the strength of integration is a relative measure, we compared integration between chondrocranial- and intramembranous-derived structures to the more modularized external and internal regions of the nasal complex. RESULTS: There was significant moderate morphological integration between chondrocranial- versus intramembranous-derived regions of the nasal complex. Moreover, integration between chondrocranial- versus intramembranous-derived structures was consistently stronger when compared to external versus internal regions for both the symmetric and asymmetric components of variation. Thus, more covariation within the nasal complex could be explained by the relationship between chondrocranial- and intramembranous-derived structures. CONCLUSIONS: Our results suggest that the interaction between chondrocranial- and intramembranous-derived structures may be an important determinant in the patterning of nasal complex variation. PMID- 29566425 TI - Cognitive-behavioural interventions for attention deficit hyperactivity disorder (ADHD) in adults. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a developmental condition characterised by symptoms of inattention, hyperactivity and impulsivity, along with deficits in executive function, emotional regulation and motivation. The persistence of ADHD in adulthood is a serious clinical problem.ADHD significantly affects social interactions, study and employment performance.Previous studies suggest that cognitive-behavioural therapy (CBT) could be effective in treating adults with ADHD, especially when combined with pharmacological treatment. CBT aims to change the thoughts and behaviours that reinforce harmful effects of the disorder by teaching people techniques to control the core symptoms. CBT also aims to help people cope with emotions, such as anxiety and depression, and to improve self-esteem. OBJECTIVES: To assess the effects of cognitive-behavioural-based therapy for ADHD in adults. SEARCH METHODS: In June 2017, we searched CENTRAL, MEDLINE, Embase, seven other databases and three trials registries. We also checked reference lists, handsearched congress abstracts, and contacted experts and researchers in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) evaluating any form of CBT for adults with ADHD, either as a monotherapy or in conjunction with another treatment, versus one of the following: unspecific control conditions (comprising supportive psychotherapies, no treatment or waiting list) or other specific interventions. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures suggested by Cochrane. MAIN RESULTS: We included 14 RCTs (700 participants), 13 of which were conducted in the northern hemisphere and 1 in Australia.Primary outcomes: ADHD symptomsCBT versus unspecific control conditions (supportive psychotherapies, waiting list or no treatment)- CBT versus supportive psychotherapies: CBT was more effective than supportive therapy for improving clinician-reported ADHD symptoms (1 study, 81 participants; low-quality evidence) but not for self-reported ADHD symptoms (SMD -0.16, 95% CI -0.52 to 0.19; 2 studies, 122 participants; low-quality evidence; small effect size).- CBT versus waiting list: CBT led to a larger benefit in clinician-reported ADHD symptoms (SMD -1.22, 95% CI -2.03 to -0.41; 2 studies, 126 participants; very low quality evidence; large effect size). We also found significant differences in favour of CBT for self-reported ADHD symptoms (SMD -0.84, 95% CI -1.18 to -0.50; 5 studies, 251 participants; moderate-quality evidence; large effect size).CBT plus pharmacotherapy versus pharmacotherapy alone: CBT with pharmacotherapy was more effective than pharmacotherapy alone for clinician-reported core symptoms (SMD -0.80, 95% CI -1.31 to -0.30; 2 studies, 65 participants; very low-quality evidence; large effect size), self-reported core symptoms (MD -7.42 points, 95% CI -11.63 points to -3.22 points; 2 studies, 66 participants low-quality evidence) and self-reported inattention (1 study, 35 participants).CBT versus other interventions that included therapeutic ingredients specifically targeted to ADHD: we found a significant difference in favour of CBT for clinician reported ADHD symptoms (SMD -0.58, 95% CI -0.98 to -0.17; 2 studies, 97 participants; low-quality evidence; moderate effect size) and for self-reported ADHD symptom severity (SMD -0.44, 95% CI -0.88 to -0.01; 4 studies, 156 participants; low-quality evidence; small effect size).Secondary outcomesCBT versus unspecific control conditions: we found differences in favour of CBT compared with waiting-list control for self-reported depression (SMD -0.36, 95% CI -0.60 to -0.11; 5 studies, 258 participants; small effect size) and for self reported anxiety (SMD -0.45, 95% CI -0.71 to -0.19; 4 studies, 239 participants; small effect size). We also observed differences in favour of CBT for self reported state anger (1 study, 43 participants) and self-reported self-esteem (1 study 43 participants) compared to waiting list. We found no differences between CBT and supportive therapy (1 study, 81 participants) for self-rated depression, clinician-rated anxiety or self-rated self-esteem. Additionally, there were no differences between CBT and the waiting list for self-reported trait anger (1 study, 43 participants) or self-reported quality of life (SMD 0.21, 95% CI -0.29 to 0.71; 2 studies, 64 participants; small effect size).CBT plus pharmacotherapy versus pharmacotherapy alone: we found differences in favour of CBT plus pharmacotherapy for the Clinical Global Impression score (MD -0.75 points, 95% CI -1.21 points to -0.30 points; 2 studies, 65 participants), self-reported depression (MD -6.09 points, 95% CI -9.55 points to -2.63 points; 2 studies, 66 participants) and self-reported anxiety (SMD -0.58, 95% CI -1.08 to -0.08; 2 studies, 66 participants; moderate effect size). We also observed differences favouring CBT plus pharmacotherapy (1 study, 31 participants) for clinician reported depression and clinician-reported anxiety.CBT versus other specific interventions: we found no differences for any of the secondary outcomes, such as self-reported depression and anxiety, and findings on self-reported quality of life varied across different studies. AUTHORS' CONCLUSIONS: There is low-quality evidence that cognitive-behavioural-based treatments may be beneficial for treating adults with ADHD in the short term. Reductions in core symptoms of ADHD were fairly consistent across the different comparisons: in CBT plus pharmacotherapy versus pharmacotherapy alone and in CBT versus waiting list. There is low-quality evidence that CBT may also improve common secondary disturbances in adults with ADHD, such as depression and anxiety. However, the paucity of long-term follow-up data, the heterogeneous nature of the measured outcomes, and the limited geographical location (northern hemisphere and Australia) limit the generalisability of the results. None of the included studies reported severe adverse events, but five participants receiving different modalities of CBT described some type of adverse event, such as distress and anxiety. PMID- 29566426 TI - Morphological integration of anatomical, developmental, and functional postcranial modules in the crab-eating macaque (Macaca fascicularis). AB - OBJECTIVES: Integration and modularity reflect the coordinated action of past evolutionary processes and, in turn, constrain or facilitate phenotypic evolvability. Here, we analyze magnitudes of integration in the macaque postcranium to test whether 20 a priori defined modules are (1) more tightly integrated than random sets of postcranial traits, and (2) are differentiated based on mode of definition, with developmental modules expected to be more integrated than functional or anatomical modules. MATERIALS AND METHODS: The 3D morphometric data collected for eight limb and girdle bones for 60 macaques were collated into anatomical, developmental, and functional modules. A resampling technique was used to create random samples of integration values for each module for statistical comparison. RESULTS: Our results found that not all a priori defined modules were more strongly integrated than random samples of postcranial traits and that specific types of modules did not present consistent patterns of integration. Rather, girdle and joint modules were consistently less integrated than limb modules, and forelimb elements were less integrated than hindlimbs. DISCUSSION: The results suggest that morphometrically complex modules tend to be less integrated than simple limb bones, irrespective of the number of available traits. However, differences in integration of the fore- and hindlimb more likely reflects the multitude of locomotory, feeding, and social functions involved. It remains to be tested whether patterns of integration identified here are primate universals, and to what extent they vary depending on phylogenetic or functional factors. PMID- 29566427 TI - Risk of major amputation in patients with intermittent claudication undergoing early revascularization. AB - BACKGROUND: Revascularization is being used increasingly for the treatment of intermittent claudication and yet few studies have reported the long-term outcomes of this strategy. The aim of this study was to compare the long-term outcome of patients with intermittent claudication who underwent revascularization compared with a group initially treated without revascularization. METHODS: Patients with symptoms of intermittent claudication and a diagnosis of peripheral arterial disease were recruited from outpatient clinics at three hospitals in Queensland, Australia. Based on variation in the practices of different vascular specialists, patients were either treated by early revascularization or received initial conservative treatment. Patients were followed in outpatient clinics using linked hospital admission record data. The primary outcome was the requirement for major amputation. Kaplan-Meier curves, Cox regression and competing risks analyses were used to compare major amputation rates. RESULTS: Some 456 patients were recruited; 178 (39.0 per cent) underwent early revascularization and 278 (61.0 per cent) had initial conservative treatment. Patients were followed for a mean(s.d.) of 5.00(3.37) years. The estimated 5-year major amputation rate was 6.2 and 0.7 per cent in patients undergoing early revascularization and initial conservative treatment respectively (P = 0.003). Early revascularization was associated with an increased requirement for major amputation in models adjusted for other risk factors (relative risk 5.40 to 4.22 in different models). CONCLUSION: Patients presenting with intermittent claudication who underwent early revascularization appeared to be at higher risk of amputation than those who had initial conservative treatment. PMID- 29566429 TI - Use of the Physician Orders for Scope of Treatment Program in Indiana Nursing Homes. AB - OBJECTIVES: To assess the use of the Indiana Physician Orders for Scope of Treatment (POST) form to record nursing home (NH) resident treatment preferences and associated practices. DESIGN: Survey. SETTING: Indiana NHs. PARTICIPANTS: Staff responsible for advance care planning in 535 NHs. MEASUREMENTS: Survey about use of the Indiana POST, related policies, and educational activities. METHODS: NHs were contacted by telephone or email. Nonresponders were sent a brief postcard survey. RESULTS: Ninety-one percent (n=486) of Indiana NHs participated, and 79% had experience with POST. Of the 65% of NHs that complete POST with residents, 46% reported that half or more residents had a POST form. POST was most often completed at the time of admission (68%). Only 52% of participants were aware of an existing facility policy regarding use of POST; 80% reported general staff education on POST. In the 172 NHs not using POST, reasons for not using it included unfamiliarity with the tool (23%) and lack of facility policies (21%). CONCLUSION: Almost 3 years after a grassroots campaign to introduce the voluntary Indiana POST program, a majority of NHs were using POST to support resident care. Areas for improvement include creating policies on POST for all NHs, training staff on POST conversations, and considering processes that may enhance the POST conversation, such as finding an optimal time to engage in conversations about treatment preferences other than a potentially rushed admission process. PMID- 29566428 TI - Elder Abuse Identification in the Prehospital Setting: An Examination of State Emergency Medical Services Protocols. AB - OBJECTIVES: To describe statewide emergency medical service (EMS) protocols relating to identification, management, and reporting of elder abuse in the prehospital setting. DESIGN: Cross-sectional analysis. SETTING: Statewide EMS protocols in the United States. PARTICIPANTS: Publicly available statewide EMS protocols identified from published literature, http://EMSprotocols.org, and each state's public health website. MEASUREMENTS: Protocols were reviewed to determine whether elder abuse was mentioned, elder abuse was defined, potential indicators of elder abuse were listed, management of older adults experiencing abuse was described, and instructions regarding reporting were provided. EMS protocols for child abuse were reviewed in the same manner for the purpose of comparison. RESULTS: Of the 35 publicly available statewide EMS protocols, only 14 (40.0%) mention elder abuse. Of protocols that mention elder abuse, 6 (42.9%) define elder abuse, 10 (71.4%) describe indicators of elder abuse, 8 (57.1%) provide instruction regarding management, and 12 (85.7%) provide instruction regarding reporting. Almost twice as many states met each of these metrics for child abuse. CONCLUSION: Statewide EMS protocols for elder abuse vary in regard to identification, management, and reporting, with the majority of states having no content on this subject. Expansion and standardization of protocols may increase the identification of elder abuse. PMID- 29566430 TI - Use of Antiepileptic Drugs and Dementia Risk-an Analysis of Finnish Health Register and German Health Insurance Data. AB - OBJECTIVES: To evaluate the association between regular antiepileptic drug (AED) use and incident dementia. DESIGN: Case-control analysis. SETTING: Finnish public health register and German health insurance data. PARTICIPANTS: Individuals with dementia of any type (German data, N=20,325) and Alzheimer's disease (AD; Finnish data, N=70,718) were matched with up to four control persons without dementia. MEASUREMENTS: We analyzed the association between regular AED use and dementia. To address potential protopathic bias, a lag time of 2 years between AED use and dementia diagnosis was introduced. Odds ratios (ORs) were calculated by applying conditional logistic regression, adjusted for potential confounding factors such as comorbidities and polypharmacy. RESULTS: Regular AED use was more frequent in individuals with dementia than controls. Regular use of AEDs was associated with a significantly greater risk of incident dementia (adjusted OR=1.28, 95% confidence interval (CI)=1.14-1.44) and AD (adjusted OR=1.15, 95% CI=1.09-1.22) than no AED use. We also detected a trend toward greater risk of dementia with higher exposure. When AEDs with and without known cognitive adverse effects (CAEs) were compared, a significantly greater risk of dementia was observed for substances with known CAEs (dementia: OR=1.59, 95% CI=1.36-1.86; AD: OR=1.19, 95% CI=1.11-1.27). CONCLUSION: AEDs, especially those with known CAEs, may contribute to incident dementia and AD in older persons. PMID- 29566431 TI - Dental size variability in Central African Pygmy hunter-gatherers and Bantu speaking farmers. AB - OBJECTIVES: Odontometric studies of African populations show high within-group variation in tooth size. Overall, North Africans exhibit smaller dimensions than groups from eastern and southern sub-Saharan regions, but no previous studies have analyzed the full dental metrics among extant African Pygmy hunter-gatherers and Bantu-speaking farmers. Furthermore, the population variability in tooth crown sizes from equatorial rainforest regions remains to be elucidated. MATERIALS AND METHODS: The mesiodistal and buccolingual diameters of the permanent teeth (I1-M2) were measured in vivo using high-resolution replicas from Baka Pygmies and Mvae and Yassa Bantu-speakers from Cameroon (western Africa). Analyses of variance were used to record sex-related and population-level differences in tooth sizes, and a principal component analysis of geometrically scaled measures was used to plot the odontometric variability among groups. RESULTS: Cameroonian Baka Pygmies differ in dental size from their Bantu-speaking neighbors. Molar teeth are larger in Pygmies than in Bantu individuals, while the anterior dentition is larger in the Bantu. Baka males exhibit significantly larger teeth than females, whereas sexual dimorphism in non-Pygmies is only present in the anterior dentition. DISCUSSION: Odontometric patterns and the degree of sexual dimorphism in dental size differ among Central African groups, indicating adaptation to their different forager and farmer lifestyles. In particular, the admixture of Bantu-speakers in Baka populations is smaller than that in other western Pygmy groups. The greater dental phenetic diversity in Baka compared to that of the smaller-toothed farmers suggests that ecogenetic and microevolutionary factors are influencing a particular divergence scenario. PMID- 29566432 TI - The timing and causes of a unique chimpanzee community fission preceding Gombe's "Four-Year War". AB - OBJECTIVES: While permanent group fissions are documented in humans and other primate species, they are relatively rare in male philopatric primates. One of the few apparent cases occurred in 1973 in Gombe National Park, Tanzania, when a community of chimpanzees split into two separate groups, preceding the famous "Four-Year War." We tested the hypothesis that the original group was a single cohesive community that experienced permanent fission, and investigated several potential catalysts. MATERIALS AND METHODS: We calculated association, grooming, and ranging metrics from historical data and used community detection algorithms and matrix permutation tests to determine the timing, dynamics, and causes of changes in social network subgrouping structure. RESULTS: We found that the two communities indeed split from one cohesive community, albeit one with incipient subgrouping. The degree of subgrouping in grooming and association networks increased sharply in 1971 and 1972, a period characterized by a dominance struggle between three high-ranking males and unusually high male:female sex ratios. Finally, we found a relationship between post-split community membership and previous association, grooming and ranging patterns in most periods of analysis, one that became more pronounced as the fission approached. DISCUSSION: Our analysis suggests that the community began to split during a time of an unusually male-biased sex ratio and a protracted dominance struggle, and that adult males remained with those with whom they had preferentially associated prior to the split. We discuss the costs and benefits of group membership in chimpanzees and contrast these results with group fissions in humans and other taxa. PMID- 29566433 TI - Diabetes in midlife and risk of cancer in late life: A nationwide Swedish twin study. AB - The association between diabetes and cancer risk remains controversial. Hence, we examined whether midlife diabetes is related to the risk of cancer in late-life, and whether genetic and early-life environmental factors play a role in this association. This study included 25,154 twin individuals born in 1958 or earlier from the Swedish Twin Registry. Information on cancer diagnosis in late life (aged >= 65) during 1998-2014, was derived from the National Patient and Cancer Registries. Diabetes was ascertained based on self- or informant-reported history, patient registry and antidiabetic medication use. Midlife diabetes was defined when diabetes was diagnosed before 65 years. Data were analyzed following two strategies: (i) unmatched case-control analysis for all participants using generalized estimating equation (GEE) models, and (ii) co-twin control analysis for cancer-discordant twin pairs using conditional logistic regression. Overall, 1,766 (7.0%) had midlife diabetes and 5,293 (21.0%) had cancer in late-life. In multiadjusted GEE models, the odds ratios (95% CIs) of diabetes were 10.55 (2.95 37.67) for pharynx cancer, 5.78 (1.72-19.40) for small intestine cancer, 2.37 (1.14-4.91) for liver cancer and 0.48 (0.35-0.67) for prostate cancer. In people with diabetes, diabetes duration was dose-dependently associated with cancer risk. In conditional logistic regression analysis of 176 prostate cancer discordant twin pairs, the association between midlife diabetes and prostate cancer in later life became stronger. Midlife diabetes increases the risk of pharynx, small intestine and liver cancers, but reduces prostate cancer risk in late life. Genetic and early-life environmental factors may partially contribute to the diabetes-prostate cancer association. PMID- 29566434 TI - Design, synthesis, and neuroprotective effects of dual-brain targeting naproxen prodrug. AB - A new dual-targeting naproxen prodrug conjugated with glucose and ascorbic acid for central nervous system (CNS) drug delivery was designed and synthesized in order to effectively deliver naproxen to the brain. Naproxen could be released from the prepared prodrugs when incubated with various buffers, mouse plasma, and brain homogenate. Also, the prodrug showed superior neuroprotective effect in vivo over naproxen. Our results suggest that chemical modification of therapeutics with warheads of glucose and ascorbic acid represents a promising and efficient strategy for the development of brain targeting prodrugs by utilizing the endogenous transportation mechanism of the warheads. PMID- 29566435 TI - Anaemia and thyrotoxicosis: The need to look for an alternative cause. AB - OBJECTIVES: Anaemia and thyrotoxicosis are both relatively common. It is unclear whether thyrotoxicosis results in anaemia in the absence of other causes. The aim of this study was to determine the prevalence and characteristics of anaemia in patients with thyrotoxicosis. DESIGN: A prospective cohort study of patients with thyrotoxicosis. PATIENTS: 353 patients referred to a regional endocrinology centre in New Zealand from March 2013 to November 2014 for new-onset thyrotoxicosis. MEASUREMENTS: Detailed assessment including thyroid function tests, full blood count, inflammatory markers, haematological parameters and coeliac serology. Anaemia was defined as a haemoglobin value <115 g/L (woman) or <130 g/L (men). RESULTS: Anaemia was present in 31 (8.7%) patients at diagnosis. Of these, pre-existing anaemia was present in 10, and a further 11 had one or more identifiable underlying cause(s) for the anaemia. Only 10 patients (2.8% of the entire cohort) had anaemia not clearly attributable to another cause. Median free thyroid hormone levels were higher in those with anaemia of unknown cause compared to patients with thyrotoxicosis alone. The median duration of anaemia was shorter in patients with thyrotoxicosis-associated anaemia compared to those with anaemia due to an underlying cause (1 vs 6 months, P = .001). In all patients with thyrotoxicosis-associated anaemia, the anaemia resolved, either prior to, or on becoming euthyroid. CONCLUSION: Anaemia coexisting with thyrotoxicosis is less common than previously reported and is mild and transient. Patients with thyrotoxicosis and significant anaemia should be investigated for other potential causes, particularly when anaemia persists.

PMID- 29566437 TI - Effects of bimagrumab, an activin receptor type II inhibitor, on pituitary neurohormonal axes. AB - BACKGROUND: Bimagrumab is a human monoclonal antibody inhibitor of activin type II receptors (ActRII), with anabolic action on skeletal muscle mass by blocking binding of myostatin and other negative regulators of muscle growth. Bimagrumab is under evaluation for muscle wasting and associated functional loss in hip fracture and sarcopenia, and in obesity. Bimagrumab also blocks other endogenous ActRII ligands, such as activins, which act on the neurohormonal axes, pituitary, gonads and adrenal glands. AIM: To evaluate the effect of bimagrumab on the pituitary-gonadal and pituitary-adrenal axes in humans. METHODS: Healthy men and women, aged 55 to 75 years, received bimagrumab intravenously 10 mg/kg or placebo on Day 1 and Day 29. Pituitary-gonadal and pituitary-adrenal functions were evaluated with basal hormone measurement and standard gonadotropin-releasing hormone (GnRH) and adrenocorticotropic hormone (ACTH) stimulation tests at baseline, Week 8 and at the end of study (EOS)-Week 20. RESULTS: At Week 8, follicle-stimulating hormone (FSH) levels were reduced by 42.16 IU/L (P < .001) and luteinizing hormone (LH) levels were increased by 2.5 IU/L (P = .08) over placebo in response to bimagrumab in women but not in men. Effects that were reversible after bimagrumab was cleared. Gonadal and adrenal androgen levels were not affected by exposure to bimagrumab. CONCLUSION: Bimagrumab alters the function of pituitary gonadotroph cells, consistent with blockade of activin on local ActRII. This effect is reversible with clearance of bimagrumab. Bimagrumab did not impact gonadal and adrenal androgen secretion. PMID- 29566438 TI - Rene Laennec and the origins of the stethoscope. PMID- 29566439 TI - Comparison of two melphalan protocols and evaluation of outcome and prognostic factors in multiple myeloma in dogs. AB - BACKGROUND: Multiple myeloma (MM) in dogs typically is treated with melphalan. A daily melphalan dosing schedule reportedly is well tolerated and associated with favorable outcome. Although anecdotally a pulse dose regimen has resulted in successful responses, little long-term outcome and safety data is available regarding this dosing regimen for dogs with MM. HYPOTHESIS/OBJECTIVES: (1) To compare outcome and adverse event profiles between pulse dose and daily dose melphalan schedules and (2) to report prognostic factors in dogs with MM treated with melphalan. We hypothesized that both protocols would have similar outcomes and tolerability. ANIMALS: Thirty-eight client-owned dogs diagnosed with MM receiving pulse dose (n = 17) or daily dose (n = 21) melphalan. METHODS: Retrospective cohort study assessing outcome and adverse events in dogs receiving either protocol. Risk factors were evaluated for their prognostic relevance. RESULTS: Both regimens were well tolerated and similarly effective, with an overall median survival time of 930 days. Renal disease and neutrophil-to lymphocyte ratio (NLR) were negative prognostic factors, whereas hypercalcemia and osteolytic lesions were not prognostic factors in this study population. CONCLUSIONS AND CLINICAL IMPORTANCE: Positive results support the use of either dosing regimen for the treatment of dogs with MM, and renal disease and NLR were negative prognostic factors. Prospective, controlled, and randomized studies are warranted to confirm these findings. PMID- 29566440 TI - Transcranial magnetic motor evoked potentials and magnetic resonance imaging findings in paraplegic dogs with recovery of motor function. AB - BACKGROUND: Transcranial magnetic motor evoked potentials (TMMEP) are associated with severity of clinical signs and magnetic resonance imaging (MRI) findings in dogs with spinal cord disease. HYPOTHESIS: That in initially paraplegic dogs with thoracolumbar intervertebral disc herniation (IVDH), MRI findings before surgery and TMMEPs obtained after decompressive surgery are associated with long-term neurological status and correlate with each other. ANIMALS: Seventeen client owned paraplegic dogs with acute thoracolumbar IVDH. METHODS: Prospective observational study. TMMEPs were obtained from pelvic limbs and MRI (3T) of the spinal cord was performed at initial clinical presentation. Follow-up studies were performed <= 2 days after reappearance of motor function and 3 months later. Ratios of compression length, intramedullary hyperintensities' length (T2 weighted hyperintensity length ratio [T2WLR]), and lesion extension (T2-weighted lesion extension ratio) in relation to the length of the 2nd lumbar vertebral body were calculated. RESULTS: TMMEPs could be elicited in 10/17 (59%) dogs at 1st and in 16/17 (94%) dogs at 2nd follow-up. Comparison of TMMEPs of 1st and 2nd follow-up showed significantly increased amplitudes (median from 0.19 to 0.45 mV) and decreased latencies (from 69.38 to 40.26 ms; P = .01 and .001, respectively). At 2nd follow-up latencies were significantly associated with ambulatory status (P = .024). T2WLR obtained before surgery correlated with latencies at 2nd follow up (P = .04). CONCLUSIONS: TMMEP reflect motor function recovery after severe spinal cord injury. PMID- 29566441 TI - All-cause mortality rates and home deaths decreased in children with life limiting diagnoses in Denmark between 1994 and 2014. AB - AIM: Specialised paediatric palliative care has not previously been a priority in Denmark. The aim of this study was to support its development and organisation, by examining why and where children died using official national data for 1994 2014. METHODS: We obtained data on 9462 children who died before the age of 18 from the Danish Register of Causes of Death. The causes of deaths were listed according to the codes in the International Classification of Diseases. RESULTS: The all-cause mortality rate decreased by 52% over the study period, and infants below one year accounted for 61% of all deaths. The decline in infant mortality (26%) primarily reflected fewer deaths due to congenital malformations and chromosomal abnormalities (68%) and perinatal deaths (30%). In children aged one year to 17 years, the substantial decrease (65%) was due to external causes (75%) and neoplasms (57%). The relative proportion of hospital deaths increased, while home deaths decreased. CONCLUSION: All-cause mortality rate decreased markedly, and the relative proportion of hospital deaths increased. The results may reflect more aggressive and effective treatment attempts to save lives, but some terminally ill children may be deprived of the option of dying at home. PMID- 29566443 TI - Effects of montmorency tart cherry (L. Prunus Cerasus) consumption on nitric oxide biomarkers and exercise performance. AB - The purpose of this study was to investigate the effects of Montmorency tart cherry juice (MC) on nitric oxide (NO) biomarkers, vascular function, and exercise performance. In a randomized, double-blind, placebo (PLA)-controlled, crossover study, 10 trained cyclists (mean +/- SD; VO2peak 59.0 +/- 7.0 mL/kg/min) acutely ingested 30 mL of either MC or PLA following dietary restrictions of polyphenol-rich compounds and completed 6-minutes moderate- and severe-intensity cycling bouts 1.5 hour post-ingestion on 2 occasions for each experimental condition. The severe-intensity cycling test was continued to exhaustion on 1 occasion and immediately followed by a 60-seconds all-out sprint on the other occasion. Blood pressure, pulse wave measures, tissue oxygenation index, and plasma nitrite concentration were assessed pre- and 1.5 hour post ingestion. Time to exhaustion was not different between conditions (P > .05), but peak power over the first 20 seconds (363 +/- 42 vs 330 +/- 26 W) and total work completed during the 60-seconds all-out sprint (21 +/- 3 vs 19 +/- 3 kJ) were 10% higher in the MC trial compared to the PLA trial (P < .05). Systolic blood pressure was 5 +/- 2 mm Hg lower 1.5 hour post-MC supplementation compared to PLA supplementation (P < .05). There were no differences in pulse wave measures, plasma nitrite concentration, or tissue oxygenation between the MC and PLA trials (P > .05). These results suggest that acute supplementation with MC can lower blood pressure and improve some aspects of exercise performance, specifically end sprint performance, in trained cyclists. PMID- 29566444 TI - Clinical significance of tumor mitotic rate and lack of epidermal attachment in melanoma of the head and neck. AB - BACKGROUND: The primary purpose of this study was to identify the prognostic role of primary dermal melanoma and tumor mitotic rate in melanomas of the head and neck. METHODS: A retrospective review of the histopathologic, clinical, and demographic data of 256 patients was performed to investigate the impact of primary dermal melanoma and tumor mitotic rate on sentinel lymph node positivity, recurrence, and 5-year overall and disease-free survival. RESULTS: Increased tumor mitotic rate, but not primary dermal melanoma, is a significant predictor of sentinel lymph node positivity and higher likelihood of recurrence. Survival analysis demonstrated that both increased tumor mitotic rate and primary dermal melanoma decreased the 5-year overall and disease-free survival rates of patients with head and neck melanoma lesions. CONCLUSION: Tumor mitotic rate and primary dermal melanoma may have prognostic significance for both overall and disease free survival in patients with head and neck melanoma. A larger prospective study is warranted to further elucidate prognostic factors for melanoma in the head and neck region.

AB - An update of the 2006 American College of Veterinary Internal Medicine (ACVIM) Small Animal Consensus Statement on Lyme Disease in Dogs: Diagnosis, Treatment, and Prevention was presented at the 2016 ACVIM Forum in Denver, CO, followed by panel and audience discussion and a drafted consensus statement distributed online to diplomates for comment. The updated consensus statement is presented below. The consensus statement aims to provide guidance on the diagnosis, treatment, and prevention of Lyme borreliosis in dogs and cats. PMID- 29566445 TI - A [4+2] Condensation Strategy to Imine-Linked Single-Crystalline Zeolite-Like Zinc Phosphate Frameworks. AB - Double-4-ring zinc phosphate (D4R), [Zn(dipp)(4-Py-CHO)]4 (2) (dipp=diiminopyridine), bearing four formyl groups, has been utilized as a building block (SBU) for the synthesis of a new class of imine-linked [4+2] COF like polycrystalline zinc phosphate frameworks. Reactions of 2 with a series of linear aromatic diamines results in the formation of polycrystalline frameworks [Zn4 (dipp)4 (L)2 ]n (3-6) (L=L1 to L4 , diimines formed by condensation of 4 pyridine carboxaldehyde with diamines). Employing an alternative synthetic strategy, through a diffusion-controlled slow reaction of 2 with the pre synthesized 4,4'-bispyridyl bisimine (L3 ), [Zn4 (dipp)4 (L3 )2 ]n (5') has been obtained as single crystals. Complex 5' is a 3D-framework, exhibiting a rare eightfold interpenetrated diamondoid network. The long spacer length (19.6 A) results in extensive entanglement in 5'. Powder diffraction data suggest that these compounds are isoreticular 3D-frameworks. To study the effect of the relative position of pyridyl donors with respect to the central benzidine moiety, 3,3'-bispyridyl bisimine (L5 ) was investigated as the spacer. A slow reaction of 1 b with L5 leads to the isolation of a 2D-boxed-sheet coordination polymer [Zn4 (dipp)4 (L5 )2 ]n (7). Selective formation of 3D-framework 5' from L3 and the 2D framework 7 from L5 is due to the angles created by the coordination of para- and meta-pyridyl nitrogen centers at the zinc centers of the D4R cubane. Compound 5' has been utilized as a catalyst for Knoevenagel condensation. PMID- 29566446 TI - Polymorphism of regulatory region of GHRL gene (-2531C>T) as a promising predictive factor for radiotherapy-induced oral mucositis in patients with head neck cancer. AB - BACKGROUND: The purpose of this study was to investigate the relationship between single nucleotide polymorphisms (SNP; rs1629816) in the regulatory region (c. 2531C>T) of the ghrelin (GHRL) gene and the occurrence and severity of oral mucositis caused by radiotherapy (RT) in patients with head and neck cancer. METHODS: Oral mucositis in 65 patients with head and neck cancer who underwent irradiation were assessed according to Radiation Therapy Oncology Group (RTOG)/European Organisation for Research and Treatment of Cancer (EORTC) scale. The DNA from patients with head and neck cancer was isolated from whole blood. The genotypes were determined using the minisequencing method (SNaPshot PCR). RESULTS: The frequency of occurrence of the GHRL gene (c.-2531C>T, rs1629816) genotypes were as follows: AA = 21.5%; GA = 40%; and GG = 38.5%. In case of AA genotype, there was a 7-fold decrease of the risk of occurrence of oral mucositis (of grades 2 and 3) in the sixth week of RT (AA vs GA or GG, respectively: 17.9% vs 82.1% patients; odds ratio [OR] 0.14; 95% confidence interval [CI] 0.02-0.98; P = .0481). No statistically significant differences were observed between the volume of oral cavity contours (V30, V40, and V50) depending on the GHRL genotype in patients with head and neck cancer. CONCLUSION: The study results have demonstrated an association between the AA genotype of the GHRL gene and the risk of more severe oral mucositis attributed to RT in patients with head and neck cancer. PMID- 29566447 TI - Posterior auricular artery as a novel anatomic landmark for identification of the facial nerve: A cadaveric study. AB - BACKGROUND: Despite preservation techniques, performing a parotidectomy carries a transient facial nerve dysfunction rate in up to 65% of cases and a permanent facial nerve weakness rate of 4%-7%. METHODS: The lateral aspect of the face and neck was exposed in 5 cadaveric heads (10 sides). The relationship of the posterior auricular artery (PAA) and the facial nerve was studied and recorded and descriptive measurements were taken. RESULTS: In all specimens, the facial nerve trunk crossed the PAA inferior to the stylomastoid foramen and could be identified precisely by tracing the PAA proximally. The distance from the cross point of the PAA and the facial nerve to the external meatal cartilage was 5.2 +/ 0.2 mm. CONCLUSION: The PAA represents a potential new anatomic landmark for facial nerve identification at the main trunk. PMID- 29566448 TI - Evaluation of a rehabilitation planning consult for survivors of head and neck cancer. AB - BACKGROUND: The rehabilitation planning consult (RPC) is a novel, transdisciplinary rehabilitation intervention for survivors of head and neck cancer. The study aimed to: (1) estimate recruitment and withdrawal rates, and adverse events; and (2) estimate the effect on rehabilitation indicators in survivors of head and neck cancer. METHODS: A single group pre-post study with follow-up was conducted with survivors of head and neck cancer who had completed treatment within 18 months. Outcome measures included goal attainment and quality of life indicators. RESULTS: Thirty participants (30) completed the RPC, and 20 completed follow-up. The average age was 59.8 years (SD 13.3), 23 were men, and 23 set rehabilitation goals. At follow-up, there was a large effect on goal performance (d = 1.5) and satisfaction (d = 1.5), and on the Short Form Health Survey-36 (SF-36) physical role and social functioning subscales (d = 1.0 and 0.8). There was a small to moderate effect on most other outcomes. CONCLUSION: The RPC is a promising transdisciplinary rehabilitation intervention warranting further study with a controlled trial. PMID- 29566450 TI - Segmentation of gray matter, white matter, and CSF with fluid and white matter suppression using MP2RAGE. AB - BACKGROUND: MP2RAGE can generate uniform T1 -weighted images, which have been used for brain segmentation. However, there remain concerns about carrying out fast brain segmentation. PURPOSE: To propose an acquisition-based method for fast segmentation of gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF) of healthy human brains with fluid and white matter suppression (FLAWS) using MP2RAGE. STUDY TYPE: Prospective. SUBJECTS: 12 volunteers (23-28 years, seven subjects; 51-62 years, five subjects). FIELD STRENGTH/SEQUENCES: 3T/3D MPRAGE and FLAWS. ASSESSMENT: The proposed method was evaluated by calculating tissue volumes and the spatial overlap with the segmentation results from FSL and SPM12. The processing time was recorded. STATISTICAL TESTS: A paired t-test was used to compare the tissue volumes of the proposed method with those from other segmentation methods RESULTS: For the 12 subjects, the tissue volume difference between the proposed and SPM12 were 3.2 +/- 2.8%, 4.2 +/- 2.5%, 18.2 +/- 13.1% for GM, WM, and CSF, respectively. The relative difference between the proposed and FSL was over 14% for all tissue classes. The spatial overlap between the proposed and other methods were 87-94% for GM and WM and less than 80% for CSF. The GM and WM volumes of the proposed method were not significantly different from those of SPM12 using MPRAGE as the input (P = 0.5540 and P = 0.3115, respectively). The rest of the comparisons all showed significant differences between the proposed and other methods. Statistical analysis of the two subgroups yielded similar results. The mean processing time of one subject was 6.5, 185, and 165 seconds for the proposed method, FSL, and SPM12, respectively. DATA CONCLUSION: Our method may be accurate for the segmentation of most brain structures using FLAWS. In addition, the proposed method is fast and applicable to the two distinct age ranges.

PMID- 29566449 TI - Quantitative susceptibility mapping (QSM) minimizes interference from cellular pathology in R2* estimation of liver iron concentration. AB - BACKGROUND: A challenge for R2 and R2* methods in measuring liver iron concentration (LIC) is that fibrosis, fat, and other hepatic cellular pathology contribute to R2 and R2* and interfere with LIC estimation. PURPOSE: To examine the interfering effects of fibrosis, fat, and other lesions on R2* LIC estimation and to use quantitative susceptibility mapping (QSM) to reduce these distortions. STUDY TYPE: Prospective. PHANTOMS, SUBJECTS: Water phantoms with various concentrations of gadolinium (Gd), collagen (Cl, modeling fibrosis), and fat; nine healthy controls with no known hepatic disease, nine patients with known or suspected hepatic iron overload, and nine patients with focal liver lesions. FIELD STRENGTH/SEQUENCE: The phantoms and human subjects were imaged using a 3D multiecho gradient-echo on clinical 1.5T and 3T MRI systems. ASSESSMENT: QSM and R2* images were postprocessed from the same gradient-echo data. Fat contributions to susceptibility and R2* were corrected in signal models for LIC estimation. STATISTICAL TESTS: Polynomial regression analyses were performed to examine relations among susceptibility, R2* and true [Gd] and [Cl] in phantoms, and among susceptibility and R2* in patient livers. RESULTS: In phantoms, R2* had a strong nonlinear dependency on [Cl], [fat], and [Gd], while susceptibility was linearly dependent (R2 > 0.98). In patients, R2* was highly sensitive to liver pathological changes, including fat, fibrosis, and tumors, while QSM was relatively insensitive to these abnormalities (P = 0.015). With moderate iron overload, liver susceptibility and R2* were not linearly correlated over a common R2* range [0, 100] sec-1 (P = 0.35). DATA CONCLUSION: R2* estimation of LIC is prone to substantial nonlinear interference from fat, fibrosis, and other lesions. QSM processing of the same gradient echo MRI data can effectively minimize the effects of cellular pathology. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 1 J. Magn. Reson.

AB - OBJECTIVE: To identify the molecular genetic etiology of an individual with a dysmorphic face, unusual teeth mobility, and root resorption. SUBJECTS AND METHODS: DNA samples were collected from a trio of family members, and whole exome sequencing was performed. RESULTS: Mutational analysis revealed a de novo mutation (c.6787C>T) in the last exon of the NOTCH2 gene. This mutation would introduce a premature stop codon [p.(Gln2263*)] and generate a truncated protein without C-terminus, escaping from the nonsense-mediated decay system. Sanger sequencing confirmed that this mutation was generated spontaneously. CONCLUSIONS: In this study, we identified a novel nonsense mutation in the last exon of the NOTCH2 gene causing Hajdu-Cheney syndrome. We described the genotype and phenotype correlation and the related dental complications. These results will advance the understanding of the NOTCH2 signaling in periodontitis and root resorption. PMID- 29566452 TI - Analysis of circulating tumor DNA does not improve the clinical management of patients with locally advanced and metastatic papillary thyroid carcinoma. AB - BACKGROUND: Circulating cell-free tumor DNA (ctDNA) in plasma is a promising noninvasive instrument for cancer monitoring. Detection of BRAFV600E on ctDNA of patients with papillary thyroid carcinoma (PTC) may represent an indicator of tumor aggressiveness and progression. METHODS: Eighty-three plasma samples were collected from 70 patients with thyroid nodules undergoing surgery and from 13 patients with PTC causing distant metastases. A total of 59 PTCs from both groups were evaluated for BRAF mutation on tumor tissue and on ctDNA from plasma samples by real-time polymerase chain reaction (PCR) and digital PCR. RESULTS: Of 59 PTCs, 22 were BRAFV600E mutated (37.3%). The corresponding ctDNA was negative by using both techniques. CONCLUSION: Although highly sensitive techniques were used, in our study, circulating BRAFV600E alleles were never detected in the plasma of patients with PTC; therefore, our results raise the question about the clinical usefulness of BRAFV600E analysis on ctDNA of patients with PTC. PMID- 29566453 TI - Analysis of state laws on informed consent for clinical genetic testing in the era of genomic sequencing. AB - This article assesses the adequacy of informed consent to clinical genetic testing laws based on an examination of 15 states with institutions that had been involved in a National Institutes of Health-supported Clinical Sequencing Exploratory Research Consortium project. We identified relevant statutory provisions through a legal search engine and included statutes that describe the informed consent requirements for clinical genetic testing and/or the protections for genetic material, information, or data. We found that statutory definitions were often limited in problematic ways, such as focusing only on variants known to be associated with disease or negative health effects or associated with asymptomatic disease. Some statutes required complex levels of detail if applied to genomic technologies and set confusing disclosure standards for current use and future access. Others had exceptions from informed consent requirements for future research use, limited requirements for the destruction of specimens as opposed to derived data, or linked key definitional components to the evolving concept of "identifiability." Further reform and research are needed to ensure that state law protections advance as rapidly as the science they aspire to enable. PMID- 29566454 TI - Bringing Nanotubes into Line.

The new method for two-dimensional liquid crystal imprinting allows for the alignment of molecules and materials on oxide surfaces. PMID- 29566455 TI - Determination of organophosphate flame retardants in soil and fish using ultrasound-assisted extraction, solid-phase clean-up, and liquid chromatography with tandem mass spectrometry. AB - A solid-liquid extraction method in combination with high-performance liquid chromatography and tandem mass spectrometry was developed and optimized for extraction and analysis of organophosphorus flame retardants in soil and fish. Methanol was chosen as the optimum extraction solvent, not only in terms of extraction efficiency, but also for its broader analyte coverage. The subsequent clean-up by solid-phase extraction is required to eliminate matrix coextractives and reduce matrix effects. Recoveries of the optimized method were 50-121% for soil and 47-123% for biota, both with high precision (RSDs <12% in soil and <23% in biota). The method limits of detection ranged from 0.06 to 0.20 ng/g dry weight and between 0.02 and 0.30 ng/g wet weight for soil and biota samples, respectively. However, samples with a high lipid content produce several problems as solid-phase extraction cartridge clogging that increase variability and analysis time. The method was successfully applied for the determination of organophosphorus flame retardants in soil and fish from L'Albufera Natural Park (Valencia, Spain). Target compounds were detected in all soil and fish samples with values varying from 13.8 to 89.7 ng/g dry weight and from 3.3 to 53.0 ng/g wet weight, respectively. PMID- 29566457 TI - How frequent and important is behavioral thermoregulation by embryonic reptiles? AB - The debate about behavioral thermoregulation inside reptile eggs centers on the frequency (and hence, biological significance) of the phenomenon, not about its validity. Both sides of the debate agree that large eggs in shallow nests laid in sun-exposed soil will experience clines in mean temperature and (especially) diel thermal variance; that embryos in the middle phase of development have the ability to reposition themselves, and room to do so; and that small changes in developmental temperatures can influence offspring fitness. Equally, all protagonists agree that thermal clines will be too low in some other kinds of nests, and that embryonic repositioning is impossible very early and very late in development. Based on an array of other fitness-enhancing behaviors exhibited by tetrapod embryos, and general principles for recognizing adaptation, we conclude that behavioral thermoregulation inside the egg likely is adaptive in some but not all reptile species. We identify productive directions for empirical research to resolve points of contention. PMID- 29566456 TI - Systematic review of outcome measures following chemoradiotherapy for the treatment of anal cancer (CORMAC). AB - AIM: Six Phase III randomized trials have determined the effectiveness of chemoradiotherapy as primary treatment for anal squamous cell carcinoma (ASCC), but outcomes reported in these trials varied widely, hindering evidence synthesis. To improve reporting in all future trials, we aim to develop a core outcomes set (COS). As the first stage of COS development, we undertook a systematic review to summarize the outcomes reported in studies evaluating chemoradiotherapy for ASCC. METHOD: Systematic literature searches identified studies evaluating radiotherapy or chemoradiotherapy for ASCC. Outcomes and accompanying definitions were extracted verbatim and categorized into domains. RESULTS: From 5170 abstracts, we identified 95 eligible studies, reporting 1192 outcomes and 533 unique terms. We collapsed these terms into 86 standardized outcomes and five domains: survival; disease activity; life impact [including quality of life (QoL)]; delivery of care; and toxicity. The most commonly reported domains were survival and disease activity, reported in 74 (86%) and 54 (62%) studies, respectively. No outcome was reported in every publication. Over half (43/86) of the standardized outcome terms were reported in fewer than five studies, and 21 (25%) were reported in a single study only. There was wide variation in definitions of disease-free survival, colostomy-free survival and progression-free survival (PFS). Anal continence was reported in only 35 (41%) studies. CONCLUSION: Outcomes reported in studies evaluating chemoradiotherapy for ASCC were heterogenous and definitions varied widely. Outcomes likely to be important to patients, such as ano-rectal function, toxicity and QoL, have been neglected. A COS for future trials will address these issues. PMID- 29566458 TI - Chronic Stress and Impulsive Risk-Taking Predict Increases in Visceral Fat over 18 Months. AB - OBJECTIVE: The aim of this study was to examine whether baseline chronic stress and impulsive risk-taking synergistically predict changes in visceral fat among healthy mothers in an observational, longitudinal, 18-month study. METHODS: A prospective cohort of 113 adult women (age, mean +/- SD: 42.83 +/- 4.70; BMI, mean +/- SD: 24.86 +/- 4.32; 74%, n = 84 white) completed assessments at baseline and 18-month follow-up. Chronically stressed mothers caring for a child with an autism spectrum disorder ("caregivers"; n = 72 participants) were compared with lower stress mothers caring for a neurotypical child ("controls"; n = 41). This study objectively assessed impulsive risk-taking by using the Behavioral Analog Risk Task at baseline and assessed visceral fat at baseline and 18-month follow up by using bioelectrical impedance (ViScan; Tanita Corporation, Tokyo, Japan). RESULTS: The interaction of baseline chronic caregiving stress and impulsive risk taking predicted an 18-month change in visceral fat, such that greater impulsive risk-taking was associated with greater 18-month increases in visceral fat among caregivers (beta = 0.423; P = 0.005) but not among controls (beta = -0.030; P = 0.802), both in unadjusted models and after accounting for covariates. Neither chronic stress nor impulsive risk-taking independently predicted 18-month changes in visceral fat. CONCLUSIONS: The combination of high chronic stress and high impulsive risk-taking may increase risk for visceral fat gain over time and therefore may be an important intervention target in obesity prevention. PMID- 29566459 TI - Enormous expansion of the chemosensory gene repertoire in the omnivorous German cockroach Blattella germanica. AB - The acquisition of genome sequences from a wide range of insects and other arthropods has revealed a broad positive correlation between the complexity of their chemical ecology and the size of their chemosensory gene repertoire. The German cockroach Blattella germanica is an extreme omnivore and has the largest chemosensory gene repertoire known for an arthropod, exceeding even the highly polyphagous spider mite Tetranychus urticae. While the Odorant Receptor family is not particularly large, with 123 genes potentially encoding 134 receptors (105 intact), the Gustatory Receptor family is greatly expanded to 431 genes potentially encoding 545 receptors (483 intact), the largest known for insects and second only to the spider mite. The Ionotropic Receptor family of olfactory and gustatory receptors is vastly expanded to at least 897 genes (604 intact), the largest size known in arthropods, far surpassing the 150 known from the dampwood termite Zootermopsis nevadensis. Commensurately, the Odorant Binding Protein family is expanded to the largest known for insects at 109 genes (all intact). Comparison with the far more specialized, but phylogenetically related termite, within the Dictyoptera, reveals considerable gene losses from the termite, and massive species-specific gene expansions in the cockroach. The cockroach has lost function of 11%-41% of these three chemoreceptor gene families to pseudogenization, and most of these are young events, implying rapid turnover of genes along with these major expansions, presumably in response to changes in its chemical ecology. PMID- 29566461 TI - Surfactant deficiency syndrome in an infant with a C-terminal frame shift in ABCA3: A case report. AB - Deficiency in ATP binding cassette A3 (ABCA3) causes neonatal respiratory distress, hypoxemic respiratory failure, and interstitial lung disease. ABCA3 transports phospholipids into the lamellar bodies of type II alveolar cells, a critical step in alveolar surfactant production. We report a term infant with ABCA3 surfactant deficiency syndrome with the E292V (c.875A>T; p.Glu292Val) mutation in trans with a novel C-terminal frame shift mutation (c.4938delC; p.Met1647fs). This mutation removes the final 58 amino acids and substitutes 33 incorrect amino acids. The frame shift spares membrane spanning and nucleotide binding domains, but disrupts a highly conserved C-terminal domain, which includes sequence motifs necessary for the function of human paralogs ABCA1, ABCA4, and the bacterial homolog DrrA. This observation suggests the C-terminal domain is also required for normal function of ABCA3. PMID- 29566460 TI - Inherently Lean Rats Have Enhanced Activity and Skeletal Muscle Response to Central Melanocortin Receptors. AB - OBJECTIVE: Activity thermogenesis and energy expenditure (EE) are elevated in intrinsically lean rats (high-capacity runners [HCR]) and are also stimulated by melanocortin receptor activation in the ventromedial hypothalamus (VMH). This study determined whether HCR are more responsive to central modulation of activity EE compared with low-capacity runners (LCR). METHODS: HCR and LCR rats received intra-VMH microinjections of melanotan II (MTII), a mixed melanocortin receptor agonist. Changes in EE, respiratory exchange ratio, activity EE, muscle heat, norepinephrine turnover, and muscle energetic modulators were compared. RESULTS: HCR were significantly more responsive to intra-VMH MTII-induced changes in EE, activity EE, norepinephrine turnover to some muscle subgroups, and muscle mRNA expression of some energetic modulators. Though HCR had high muscle activity thermogenesis, limited MTII-induced modulation of muscle thermogenesis during activity was seen in LCR only. CONCLUSIONS: An inherently lean, high-capacity rat phenotype showed elevated response to central melanocortin stimulation of activity EE and use of fat as fuel. This may be driven by sympathetic outflow to skeletal muscle, which was elevated after MTII. Central melanocortin receptor activation also altered skeletal muscle energetic modulators in a manner consistent with elevated EE and lowered respiratory exchange ratio. PMID- 29566462 TI - Safety profile of blind bronchial sampling-A prospective study in pediatric intensive care unit. AB - OBJECTIVE: To study the safety profile of blind bronchial sampling in mechanically ventilated children. DESIGN: Prospective interventional study. SETTING: Tertiary level pediatric intensive care unit of a multispecialty hospital. PATIENTS: Children aged 1 month to 16 years on mechanical ventilator for >=48 h, were assessed by clinical pulmonary infection score for ventilator associated pneumonia (VAP). INTERVENTIONS: Blind bronchial sampling was performed following standard procedural guidelines. The hemodynamic, ventilation parameters, and arterial blood gases done before, and in next 24 h post procedure were recorded and compared. MEASUREMENTS AND MAIN RESULTS: Among the 40 enrolled children, VAP was suspected at 5.8 +/- 3.7 days post intubation with insignificant increase in median (IQR) PELOD score to 15 (11-23) from 13.5 (11 23) (P value 0.29). A statistically significant increase in mean blood pressure (75.5 +/- 14.7 to 79.1 +/- 14.2, P 0.04) and transient drop in SpO2 (98.2 +/- 2.3 to 92.2 +/- 9.2, P < 0.001) were noted with insignificant change in heart rate (128.7 +/- 25.6 vs 132.0 +/- 30.8, P 0.52), though these variations were clinically not significant. There were no major complications like significant airway bleed, arrhythmia, air leaks, edema, and change in pulmonary infiltrates during the procedure. There were no significant (either clinical or statistical) effects of BBS procedure, whether transient or prolonged, on ventilatory requirements or gas exchange parameters. CONCLUSIONS: Blind bronchial sampling is a safe procedure in children with no major adverse events related to hemodynamics, oxygenation, and ventilation parameters. PMID- 29566463 TI - Supervised Physical Training Improves Weight Loss After Roux-en-Y Gastric Bypass Surgery: A Randomized Controlled Trial. AB - OBJECTIVE: Bariatric surgery results in significant weight loss and reduces cardiovascular morbidity. However, a large variation in postsurgery weight loss is seen. Physical activity promotes weight loss in nonsurgically treated subjects with obesity. The aim of this study was to investigate the effects of 6 months of supervised physical training following Roux-en-Y gastric bypass surgery (RYGB) on body weight and cardiovascular risk markers. METHODS: Sixty participants eligible for RYGB were included. Six months post surgery, the participants were randomly assigned to either twice-weekly supervised physical training sessions in a fitness center (INT) or a control group (CON) for 26 weeks. Before surgery and 6, 12, and 24 months after surgery, the participants underwent an examination program that included anthropometric measurements, blood pressure, heart rate, blood samples, and an abdominal computed tomography scan. RESULTS: RYGB significantly reduced body weight and improved cardiovascular risk markers (all P < 0.01). The supervised physical training intervention resulted in a 4.2-kg (CI: 0.2 to -8.3 kg) lower body weight in INT compared with CON at the study end (P = 0.042). The high-density lipoprotein concentration was significantly higher in INT than in CON at the termination of the intervention, but this was not maintained at the 24-months examination. CONCLUSIONS: Physical training following RYGB improves weight loss and cardiovascular health. PMID- 29566464 TI - Why Do Mania and Suicide Occur Most Often in the Spring? PMID- 29566466 TI - What Should We Concern in Reporting Conflict of Interest for Submission of Manuscript in the Psychiatry Investigation? PMID- 29566467 TI - Tarsal switch using an anterior approach to correct severe ptosis. AB - BACKGROUND: To present the outcomes of the tarsal switch procedure using an anterior approach to correct severe ptosis with poor levator muscle function (<4 mm) with absent or poor Bell's phenomenon. METHODS: This retrospective case series included 11 patients with severe neurogenic or acquired myogenic palpebral ptosis. All patients underwent the tarsal switch procedure through an anterior approach from 2012 to 2015. Margin reflex distance (MRD1 and MRD2) and the palpebral fissure were evaluated preoperatively and postoperatively. Data were compared using the Wilcoxon signed-rank test. P-values <0.05 were considered to indicate statistical significance. RESULTS: Surgery was performed on 18 eyelids (11 patients). The median age at surgery was 57 years (range, 29-86 years). Four patients had unilateral ptosis and seven had bilateral ptosis. Nine patients had myogenic ptosis and two had neurogenic ptosis. Postoperatively, the chin-up position improved in all patients. The MRD1 increased statistically significantly, from 0 mm preoperatively to 1.0 mm postoperatively (P=0.001). The MRD2 decreased statistically significantly, from 4.5 mm preoperatively to 3.0 mm postoperatively (P=0.001). The palpebral fissure did not change (4.0 mm preoperatively to 4.0 mm postoperatively) (P=0.13). CONCLUSIONS: The tarsal switch procedure through an anterior approach is an effective alternative for correcting severe ptosis, especially neurogenic or acquired myogenic ptosis. This procedure can be performed with minimal risk of ocular surface exposure and provides stable outcomes. PMID- 29566468 TI - Lymphatic vessel mapping in the upper extremities of a healthy Korean population. AB - BACKGROUND: Intraoperative indocyanine green (ICG) lymphography can effectively detect functioning lymph vessels in edematous limbs. However, it is sometimes difficult to clearly identify their course in later-stage edematous limbs. For this reason, many surgeons rely on experience when they decide where to make the skin incision to locate the lymphatic vessels. The purpose of this study was to elucidate lymphatic vessel flow patterns in healthy upper extremities in a Korean population and to use these findings as a reference for lymphedema treatment. METHODS: ICG fluorescence lymphography was performed by injecting 1 mL of ICG into the second web space of the hand. After 4 hours, fluorescence images of lymphatic vessels were obtained with a near-infrared camera, and the lymphatic vessels were marked. Three landmarks were designated: the radial styloid process, the mid-portion of the cubital fossa, and the lower border of the deltopectoral groove. A straight line connecting the points was drawn, and the distance between the connected lines and the marked lymphatic vessels was measured at 8 points. RESULTS: There were 30 healthy upper extremities (15 right and 15 left). The average course of the main lymph vessels passed 26.0+/-11.6 mm dorsal to the styloid process, 5.7+/-40.7 mm medial to the mid-cubital fossa, and 31.3+/-26.1 mm medial to the three-quarters point of the upper landmark line. CONCLUSIONS: The main functioning lymphatic vessel follows the course of the cephalic vein at the forearm level, crosses the mid-cubital point, and travels medially toward the mid-axilla. PMID- 29566469 TI - Volumetric lipoinjection of the fronto-orbital and temporal complex with adipose stem cells for the aesthetic restoration of sequelae of craniosynostosis. AB - BACKGROUND: Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face. METHODS: Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini approaches to ensure adequate distribution. RESULTS: Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients' parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients' facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance. CONCLUSIONS: We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients' self-esteem starting at an early age.

AB - Subpectoral breast reconstruction using implants and meshes have been used widely in Europe, the United States and the United Kingdom. Although this technique has several advantages, animation deformity is a well-documented problem. We propose a new grading system to classify breast animation in patients undergoing subpectoral implant based breast reconstruction. We also discuss different techniques to avoid and correct animation deformity. PMID- 29566471 TI - Reduction mammoplasty as a treatment for symptomatic central venous stenosis. AB - Central venous stenosis is a rare cause of unilateral breast edema occurring in hemodialysis patients that needs to be differentiated from other differential diagnoses, including, but not limited to, inflammatory breast carcinoma, mastitis, lymphedema, and congestive heart failure. All reports of similar cases in the available literature have described improvement or resolution of the edema after treatment. Herein, we report and discuss the pathophysiology of breast edema formation in a patient who presented with massive left-sided breast edema 7 years after being diagnosed with central venous stenosis. Medical and minimally invasive therapy had not been successful, so she underwent reduction mammoplasty to relieve the symptoms. PMID- 29566472 TI - [Endoscopic Treatment for Esophageal Cancer]. AB - Esophageal cancer incidence rate per 100,000 is 4.7 in 2013, which accounts for 1.1% of the total cancer incidence in Korea. Superficial esophageal squamous cell carcinoma is frequently detected in persons undergoing upper endoscopy for gastrointestinal symptoms or for gastric cancer screening. Esophagectomy with lymph node dissection is the standard treatment for esophageal cancer. However, given the considerable morbidity and mortality of esophagectomy, endoscopic resection has become the standard of care for most cases of superficial esophageal squamous cell carcinoma without metastasis. In addition, endoscopic submucosal dissection has increased the cure rate, even when the tumor is large, compared to endoscopic mucosal resection. Thus, endoscopic submucosal dissection is the treatment of choice for superficial esophageal squamous cell carcinoma with a negligible risk of lymph node metastasis. Endoscopic resection is usually associated with a low risk of morbidity and no mortality, and has also shown favorable long-term outcomes. However, the long-term risk of metastasis remains after endoscopic resection, which varies according to the characteristics of tumor. This review describes the indication and outcomes of endoscopic resection, complications of endoscopic resection, and management after treatment. PMID- 29566473 TI - Comparative Study of Esophageal Self-expandable Metallic Stent Insertion and Gastrostomy Feeding for Dysphagia Caused by Lung Cancer. AB - Background/Aims: Dysphagia is encountered in a large proportion of patients with lung cancer and is associated with malnutrition and a poor quality of life. This study compared the clinical outcomes of self-expandable metallic stent (SEMS) insertion and percutaneous gastrostomy (PG) feeding for patients with lung cancer and dysphagia. Methods: A total of 261 patients with lung cancer, who underwent either SEMS insertion (stent group) or PG (gastrostomy group) as an initial treatment procedure for dysphagia between July 1997 and July 2015 at the Samsung Medical Center, were reviewed retrospectively, and 84 patients with esophageal obstruction were identified. The clinical outcomes, including the overall survival, additional intervention, complications, and post-procedural nutritional status in the two groups, were compared. Results: Among the 84 patients finally analyzed, 68 patients received SEMS insertion and 16 had PG. The stent group had less cervical obstruction and more mid-esophageal obstruction than the gastrostomy group. The Kaplan-Meier curves revealed similar overall survival in the two groups. Multivariate analysis showed that the two modalities had similar survival rates (PG compared with SEMS insertion, hazard ratio 0.682, p=0.219). Fifteen patients (22.1%) in the stent group received additional intervention, whereas there was no case in the gastrostomy group (p=0.063). The decrease in the serum albumin level after the procedure was lower in the gastrostomy group than in the stent group (-0.20+/-0.54 g/dL vs. -0.65+/-0.57 g/dL, p=0.013). Conclusions: SEMS insertion and PG feeding for relieving dysphagia by lung cancer had a comparable survival outcome. On the other hand, PG was associated with a better nutritional status. PMID- 29566474 TI - Combined Extracts of Artemisia and Green Tea, Mitigated Alcoholic Gastritis Via Enhanced Heat-shock Protein 27. AB - Background/Aims: Several lines of evidence from epidemiologic and laboratory studies have shown that the consumption of Artemisia or green tea extracts (MPGT) is inversely associated with the risk of alcohol-induced damage and other chronic diseases. Supported by previous studies showing that the combined extract of Artemisia and green tea, MPGT, exerted significantly either antioxidative or anti inflammatory actions against Helicobacter pylori-associated gastric diseases, it was hypothesized that MPGT can offer protection against alcoholic gastritis. Methods: Ethanol was administered to induce gastric damage in Wistar rats, which had been pretreated with various doses of MPGT, to measure the rescuing action of a MPGT pretreatment against ethanol-induced gastric damage. In addition, the molecular mechanisms for the preventive effects were examined. Results: The MPGT pretreatment (100, 300, and 500 mg/kg) alleviated the ethanol-induced gastric damage, which was evidenced by the significant decrease in calcium-dependent phospholipase A2, MAPKs, and NF-kappaB levels compared to ethanol alone. Furthermore, the MPGT pretreatment preserved 15-prostaglandin dehydrogenase, whereas cyclooxygenase-2 was decreased significantly. All of these biochemical changes led to the significant alleviation of alcohol-associated gastric mucosal damage. Ethanol significantly increased the TUNEL positivity in the stomach, but MPGT decreased the apoptotic index significantly, which was associated with significantly lower pathological scores of ethanol-induced mucosal ulcerations. The significant protective changes observed alcoholic gastritis with MPGT were related to the increased expression of cytoprotective genes, such as heat-shock protein (HSP)27, HSP60, and PDGF. Conclusions: The efficient anti-inflammatory, anti-apoptotic, and regenerative actions of MPGT make it a potential nutrient phytoceutical to rescue the stomach from alcoholic gastritis. PMID- 29566475 TI - [Identification of Nodular Gastritis among Patients Diagnosed with Lymphofollicular Gastritis on a Gastric Biopsied Specimen]. AB - Background/Aims: Nodular gastritis (NG) is a well-known endoscopic finding observed in patients with a Helicobacter pylori infection, which may lead to invasive gastric cancer. Lymphofollicular gastritis consists of lymphoid follicles or lymphoid cell aggregates, and is common in children. The aim of this study was to identify patients with NG from those in whom gastric biopsied specimens showed lymphoid follicles and lymphoid cell aggregates. Methods: Subjects, whose gastric biopsy specimens showed lymphoid follicles or lymphoid cell aggregates, were included in this study. The inclusion criterion was that they underwent a serum pepsinogen assay on the day of upper gastrointestinal endoscopy. NG was diagnosed if the endoscopy findings revealed regular-sized, multiple, colorless subepithelial nodules. Results: Among 108 subjects who showed lymphoid follicles or lymphoid cell aggregates, 13 (12.0%) revealed NG on endoscopy, and all these subjects showed positive Giemsa staining. Patients diagnosed with NG were younger (p=0.012) and showed a female predominance (p=0.001) compared to those without NG. The mean serum pepsinogen levels were higher (p=0.001) and lymphoid follicle-dominant subjects were more common (p<0.001) in the NG subjects than in those without NG. Logistic regression analysis revealed a younger age (p=0.041) and female gender (p=0.002) to be significant independent risk factors for NG. Conclusions: NG should be distinguished from lymphofollicular gastritis because only 12% of patients showing gastric biopsy findings of lymphoid follicles and lymphoid cell aggregates demonstrated NG on endoscopy. NG is an endoscopic finding that is more common in women and in the younger population, irrespective of the biopsy findings and gastric secretory ability. PMID- 29566476 TI - Predictors of Malignancies in Patients with Inconclusive or Negative Results of Endoscopic Ultrasound-guided Fine-needle Aspiration for Solid Pancreatic Masses. AB - Background/Aims: This study analyzed the diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic solid masses in patients with or without chronic pancreatitis as well as the clinical parameters relevant to a malignancy when EUS-FNA was negative or inconclusive. Methods: A total of 97 patients, who underwent EUS-FNA for solid pancreatic masses over 2 years at a single institution, were evaluated. All patients underwent EUS-FNA for 3-5 passes with 22 or 25 G needles without an on-site cytopathologist. The final diagnosis was obtained by surgery or compatible clinical outcomes for a more than 12 month follow-up. The diagnostic yields in the patients with or without chronic pancreatitis were compared and the histories and laboratory data relevant to pancreatic ductal adenocarcinoma (PDAC) or pseudo-tumor were analyzed. Results: The final diagnoses were adenocarcinoma in 88 patients (90.7%) and inflammatory pseudo-tumor in 9 (9.3%). The results of EUS-FNA were adenocarcinoma (74), suspicious (7), atypical (5), negative (10), and inadequate specimen (1). The diagnostic accuracies were 76.9% and 91.6% in patients with or without chronic pancreatitis, respectively. Among the 23 cases with non-diagnostic results of EUS FNA, PDAC was finally diagnosed in 5 out of 7 suspicious, 3 out of 5 atypical, and 5 out of 10 negative cytology cases. The clinical parameters related to a pseudo-tumor were a history of alcohol consumption and pancreatitis, and normal alkaline phosphatase levels. Conclusions: The diagnostic accuracy of pancreatic masses in the background of chronic pancreatitis was low. When EUS-FNA produced inconclusive results, the histories of alcohol consumption, pancreatitis, and serum levels of alkaline phosphatase are useful for making a final diagnosis. PMID- 29566477 TI - Severe Intraperitoneal Hemorrhage from Pseudoaneurysm after a Large-volume Paracentesis, Successfully Treated with Microcoil Embolization. AB - Large-volume paracentesis-induced intraperitoneal hemorrhage due to pseudoaneurysm formation is rarely reported. Here, we present a 56-year-old man with alcoholic liver cirrhosis admitted for massive ascites. Large-volume paracentesis was performed. Three days later, he became pale and complained of dyspnea and abdominal distention with hypotension. Percutaneous iliac angiography revealed contrast media leakage from a branch of the left circumflex iliac artery with pseudoaneurysm. He was successfully treated with microcoil embolization. Several days later, ascitic fluid increased and large-volume paracentesis was performed again. Two days later, his hemoglobin level suddenly decreased. An abdominal computed tomography scan showed new active bleeding at the left lower lateral peritoneal cavity, just anterior to the metalic coils. Percutaneous iliac angiography revealed contrast media extravasation from a branch of the left inferior epigastric artery with formation of collateral vessel. Percutaneous embolization was successfully performed again. After coil embolization, there were no further bleeding episodes. PMID- 29566478 TI - The Usefulness of Cap-assisted Endoscopic Retrograde Cholangiopancreatography for Cannulation Complicated by a Periampullary Diverticulum. AB - Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced therapeutic procedure to manage choledocholithiasis and pancreatobiliary malignancy. On occasion, ERCP failure is encountered due to difficulties in cannulation. We assessed the safety and feasibility of cap-assisted ERCP via analyzing cases in which cannulation was complicated by periampullary diverticulum. Between November 2013 and March 2014, ERCP procedures were performed in 346 patients in our tertiary medical center. Among the 73 patients who had a periampullary diverticulum, conventional ERCP failed in 5 patients due to hidden papilla (n=3) or use of tangential approach (n=2). As a rescue method, needle knife fistulotomy and selective biliary cannulation using cap-fitted forward-viewing endoscopy were successfully used in 4 patients without major complications. Based on our experience, cap-fitted forward-viewing endoscopy was relatively easy to measure the exact position of papilla and to perform biliary cannulation properly. Therefore, we recommend using cap-assisted ERCP by forward-viewing endoscopy as a useful and safe alternative to manage patients in whom cannulation is complicated by periampullary diverticulum. PMID- 29566479 TI - A Prospective Blinded Study of Endoscopic Ultrasound Elastography in Liver Disease: Towards a Virtual Biopsy. AB - BACKGROUND/AIMS: Liver biopsy has traditionally been used for determining the degree of fibrosis, however there are several limitations. Endoscopic ultrasound (EUS) real-time elastography (RTE) is a novel technology that uses image enhancement to display differences in tissue compressibility. We sought to assess whether liver fibrosis index (LFI) can distinguish normal, fatty, and cirrhotic liver tissue. METHODS: A total of 50 patients undergoing EUS were prospectively enrolled. RTE of the liver was performed to synthesize the LFI in each patient. Univariate and multivariable analyses were performed. Chi-square and t-tests were performed for categorical and continuous variables, respectively. A p-value of <0.05 was considered significant. RESULTS: Abdominal imaging prior to endoscopic evaluation suggested normal tissue, fatty liver, and cirrhosis in 26, 16, and 8 patients, respectively. Patients with cirrhosis had significantly increased mean LFI compared to the fatty liver (3.2 vs. 1.7, p<0.001) and normal (3.2 vs. 0.8, p<0.001) groups. The fatty liver group showed significantly increased LFI compared to the normal group (3.8 vs. 1.4, p<0.001). Multivariable regression analysis suggested that LFI was an independent predictor of group features (p<0.001). CONCLUSIONS: LFI computed from RTE images significantly correlates with abdominal imaging and can distinguish normal, fatty, and cirrhotic-appearing livers; therefore, LFI may play an important role in patients with chronic liver disease. PMID- 29566480 TI - Prediction of Cancer Incidence and Mortality in Korea, 2018. AB - PURPOSE: This study aimed to report on cancer incidence and mortality for the year 2018 to estimate Korea's current cancer burden. MATERIALS AND METHODS: Cancer incidence data from 1999 to 2015 were obtained from the Korea National Cancer Incidence Database, and cancer mortality data from 1993 to 2016 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against observed years, then multiplying the projected age-specific rates by the age specific population. The Joinpoint regression model was used to determine at which year the linear trend changed significantly, we only used the data of the latest trend. RESULTS: A total of 204,909 new cancer cases and 82,155 cancer deaths are expected to occur in Korea in 2018. The most common cancer sites were lung, followed by stomach, colorectal, breast and liver. These five cancers represent half of the overall burden of cancer in Korea. For mortality, the most common sites were lung cancer, followed by liver, colorectal, stomach and pancreas. CONCLUSION: The incidence rate of all cancer in Korea are estimated to decrease gradually, mainly due to decrease of thyroid cancer. These up-to-date estimates of the cancer burden in Korea could be an important resource for planning and evaluation of cancer-control programs. PMID- 29566481 TI - Cancer Statistics in Korea: Incidence, Mortality, Survival, and Prevalence in 2015. AB - PURPOSE: This study presents the 2015 nationwide cancer statistics in Korea, including the incidence, survival, prevalence, and mortality. MATERIALS AND METHODS: Cancer incidence data from 1999 to 2015 was obtained from the Korea National Cancer Incidence Database and followed until December 31, 2016. Mortality data from 1983 to 2015 were obtained from Statistics Korea. The prevalence was defined as the number of cancer patients alive on January 1, 2016, among all cancer patients diagnosed since 1999. Crude and age-standardized rates (ASRs) for incidence, mortality and prevalence and 5-year relative survivals were also calculated. RESULTS: Herein, 214,701 and 76,855 Koreans were newly diagnosed and died from cancer in 2015, respectively. The ASRs for cancer incidence and mortality in 2015 were 258.9 and 82.0 per 100,000, respectively. The overall cancer incidence rate has increased significantly by 3.4% annually from 1999 to 2012, and started to decrease after 2012 (2012-2015, annual percent change, 6.1%). However, the overall cancer mortality has decreased 2.7% annually since 2002. The 5-year relative survival rate for patients diagnosed with cancer between 2011 and 2015 was 70.7%, an improvement from the 41.2% for patients diagnosed between 1993 and 1995. CONCLUSION: Age-standardized cancer incidence rates have decreased since 2012 and mortality rates have declined since 2002; however, the 5-year survival rates have improved remarkably from 1993-1995 to 2011-2015 in Korea. PMID- 29566482 TI - What We Talk About When We Talk About Caregiving: The Distribution of Roles in Cancer Patient Caregiving in a Family-Oriented Culture. AB - Purpose: When it comes to cancer care, the psychological well-being of family caregivers has gotten its deserved attention. However, the specific roles that the family caregivers take have not been examined as much. The current study aimed to investigate the distribution of family caregivers' roles, particularly in a family-oriented culture, Korea. Materials and Methods: A sample of 439 participants was recruited from 11 national and regional cancer centers in Korea. The participants who were 60 years old or above went through treatments for their gastric, colorectal, or lung cancer. The individual survey included questions regarding the family type, living arrangement, and the sources of support when it comes to their physical, emotional, financial, and decision-making needs. Results: The responses from the participants showed that (1) cancer caregiving is shared by multiple family caregivers; (2) the major source of support for elderly cancer patients on diverse domains was their spouse; (3) patients' reliance on their daughter(s) increased for emotional support; and (4) patients' reliance on their son(s) stood out for financial support and decision-making support. Also, the older the patients were, the heavier their reliance was on the adult children, including sons, daughters, and daughters-in-law. Conclusion: Future support programs for elderly cancer patients are suggested to involve multiple family caregivers to encourage effective and efficient intervention. Also, the limitations of the current study and the suggestions for future research are discussed. PMID- 29566484 TI - Cluster Assemblies Produced by Aggregation of Preformed Ag Clusters in Ionic Liquids. AB - Room-temperature ionic liquids (RTILs) can be used as electrosterical stabilizers for nanoparticles without adding stabilizing agents. However, the nanoparticle stability and its mechanisms are still in discussion. We deposited preformed 2 nm +/-0.6 nm silver clusters into the ionic liquid C4MIM PF6 using in situ UV/vis absorption to monitor the deposition process. The time- and temperature-dependent cluster aggregation process was studied with ex situ UV/vis absorption spectroscopy analyzed with electrodynamic calculations using generalized Mie theory. On an atomistic level, the sample structure was investigated using EXAFS and a neural network based analysis of XANES. The combination of all methods shows that an aggregation of the original 2 nm clusters without coalescence takes place, which can be controlled or stopped by choosing an appropriate sample temperature. This approach allows the controlled production of chainlike cluster aggregates in RTIL, promising for a number of applications. PMID- 29566483 TI - Sputum Active Polymyxin Lipopeptides: Activity against Cystic Fibrosis Pseudomonas aeruginosa Isolates and Their Interactions with Sputum Biomolecules. AB - The mucoid biofilm mode of growth of Pseudomonas aeruginosa ( P. aeruginosa) in the lungs of cystic fibrosis patients makes eradication of infections with antibiotic therapy very difficult. The lipopeptide antibiotics polymyxin B and colistin are currently the last-resort therapies for infections caused by multidrug-resistant P. aeruginosa. In the present study, we investigated the antibacterial activity of a series of polymyxin lipopeptides (polymyxin B, colistin, FADDI-003, octapeptin A3, and polymyxin A2) against a panel of polymyxin-susceptible and polymyxin-resistant P. aeruginosa cystic fibrosis isolates grown under planktonic or biofilm conditions in artificial sputum and their interactions with sputum component biomolecules. In sputum media under planktonic conditions, the lipopeptides FADDI-003 and octapeptin A3 displayed very promising activity against the polymyxin-resistant isolate FADDI-PA066 (polymyxin B minimum inhibitory concentration (MIC) = 32 mg/L), while retaining their activity against the polymyxin-sensitive strains FADDI-PA021 (polymyxin B MIC = 1 mg/L) and FADDI-PA020 (polymyxin B MIC = 2 mg/L). Polymyxin A2 was only effective against the polymyxin-sensitive isolates. However, under biofilm growth conditions, the hydrophobic lipopeptide FADDI-003 was inactive compared to the more hydrophilic lipopeptides, octapeptin A3, polymyxin A2, polymyxin B, and colistin. Transmission electron micrographs revealed octapeptin A3 caused reduction in the cell numbers in biofilm as well as biofilm disruption/"antibiofilm" activity. We therefore assessed the interactions of the lipopeptides with the component sputum biomolecules, mucin, deoxyribonucleic acid (DNA), surfactant, F-actin, lipopolysaccharide, and phospholipids. We observed the general trend that sputum biomolecules reduce lipopeptide antibacterial activity. Collectively, our data suggests that, in the airways, lipopeptide binding to component sputum biomolecules may reduce antibacterial efficacy and is dependent on the physicochemical properties of the lipopeptide. PMID- 29566485 TI - Structure-Based Discovery of Nonpeptide Allatostatin Analogues for Pest Control. AB - FGLamide allatostatins (ASTs) are regarded as possible insecticide candidates, although their lack of in vivo effects, rapid degradation, poor water solubility, and high production costs preclude their practical use in pest control. In contrast to previous research, the C-terminal tripeptide (FGLa) was selected as the lead compound in this study. Five nonpeptide AST analogues (2-amino-1-[3-oxo 3-(substituted-anilino)propyl]pyridinium nitrate derivatives) were designed on the basis of the structure-activity relationship and docking results of FGLa. All of the nonpeptide analogues (S1-S5) were more potent against juvenile-hormone (JH) biosynthesis than the lead compound. They significantly inhibited the biosynthesis of JH in vivo following injection. A pest-control application demonstrated that S1 and S3 have larvicidal effects following oral administration (the IC50 values were 0.020 and 0.0016 mg/g, respectively). The good oral toxicities and excellent water solubilities of S1 and S3 suggest that they have considerable potential as insecticides for pest management. PMID- 29566486 TI - Discovery of Benzenesulfonamide Derivatives as Carbonic Anhydrase Inhibitors with Effective Anticonvulsant Action: Design, Synthesis, and Pharmacological Evaluation. AB - Two series of novel benzenesulfonamide derivatives were synthesized and evaluated for their human carbonic anhydrase (CA, EC 4.2.1.1) inhibitory activity against four isoforms, hCA I, hCA II, hCA VII, and hCA IX. It was found that compounds of both series showed low to medium nanomolar inhibitory potential against all isoforms. Some of these derivatives displayed selective inhibition against the epileptogenesis related isoforms hCA II and VII, within the nanomolar range. These potent hCA II and VII inhibitors were evaluated as anticonvulsant agents against MES and sc-PTZ induced convulsions. These sulfonamides effectively abolished induced seizures in both models. Furthermore, time dependent seizure protection capability of the most potent compound was also evaluated. A long duration of action was displayed, with efficacy up to 6 h after drug administration. The compound appeared as an orally active anticonvulsant agent without showing neurotoxicity in a rotarod test, a nontoxic chemical profile being observed in subacute toxicity study. PMID- 29566487 TI - Concurrent In Vitro Synthesis and Functional Detection of Nascent Activity of the KcsA Channel under a Membrane Potential. AB - Processes involved in the functional formation of prokaryotic membrane proteins have remained elusive. Here, we developed a new in vitro membrane protein expression system to detect nascent activities of the KcsA potassium channel in lipid bilayers under an applied membrane potential. The channel was synthesized using a reconstituted Escherichia coli-based in vitro transcription/translation system (IVTT) in a water-in-oil droplet lined by a membrane. The synthesized channels spontaneously incorporated into the membrane even without the translocon machinery (unassisted pathway) and formed functional channels with the correct orientation. The single-channel current of the first appearing nascent channel was captured, followed by the subsequent appearance of multiple channels. Notably, the first appearance time shortened substantially as the membrane potential was hyperpolarized. Under a steadily applied membrane potential, this system serves as a production line of membrane proteins via the unassisted pathway, mimicking the bacterial synthetic membrane. PMID- 29566488 TI - Structure-Based Discovery and Optimization of Benzo[ d]isoxazole Derivatives as Potent and Selective BET Inhibitors for Potential Treatment of Castration Resistant Prostate Cancer (CRPC). AB - The bromodomain and extra-terminal (BET) family proteins have gained increasing interest as drug targets for treatment of castration-resistant prostate cancer (CRPC). Here, we describe the design, optimization, and evaluation of benzo[ d]isoxazole-containing compounds as potent BET bromodomain inhibitors. Cocrystal structures of the representative inhibitors in complex with BRD4(1) provided solid structural basis for compound optimization. The two most potent compounds, 6i (Y06036) and 7m (Y06137), bound to the BRD4(1) bromodomain with Kd values of 82 and 81 nM, respectively. They also exhibited high selectivity over other non BET subfamily members. The compounds potently inhibited cell growth, colony formation, and the expression of AR, AR regulated genes, and MYC in prostate cancer cell lines. Compounds 6i and 7m also demonstrated therapeutic effects in a C4-2B CRPC xenograft tumor model in mice. These potent and selective BET inhibitors represent a new class of compounds for the development of potential therapeutics against CRPC. PMID- 29566489 TI - Charged Surface Regulates the Molecular Interactions of Electrostatically Repulsive Peptides by Inducing Oriented Alignment. AB - Regulation of molecular orientation of charged dipeptides and involved interactions by electrostatic repulsion from like-charged surfaces were studied using all-atom molecular dynamics simulations. It was found that a charged surface can induce oriented alignment of like-charged peptides, and the oriented alignment leads to enhanced electrostatic repulsion between the peptide molecules. The findings are consistent with previous experimental results about the inhibition of charged protein aggregation using like-charged ion-exchange resin. Furthermore, the simulations provided molecular insights into this process, and demonstrated the distinct regulation effect of like-charged surfaces on the molecular interactions between peptides that possess an electric dipole structure. Both the charged surface and the electric dipole structure of peptides were confirmed to be crucial for the regulation. The research is expected to facilitate the rational design of surfaces or devices to regulate the behavior of amphoteric molecules such as proteins for both in vivo and in vitro applications, which would contribute to the regulation of protein-protein interactions and its application in life science and biotechnology.

AB - Motivated by the proposed use of cationic protein-modified sand for water filtration in developing nations, this study concerns the adsorption of Moringa oleifera seed proteins to silica surfaces. These proteins were prepared in model waters of varying hardness and underwent different levels of fractionation, including fatty acid extraction and cation exchange chromatography. Adsorption isotherms were measured by ellipsometry, and the zeta potentials of the resulting protein-decorated surfaces were measured by the rotating disk streaming potential method. The results indicate that the presence of fatty acids has little effect on the M. oleifera cationic protein adsorption isotherm. Adsorption from the unfractionated extract was indistinguishable from that of the cationic protein isolates at low concentrations but yielded significantly greater extents of adsorption at high concentrations. Adsorption isotherms for samples prepared in model hard and soft fresh waters were indistinguishable from each other over the measured bulk solution concentration range, but adsorption from hard or soft water was more extensive than adsorption from deionized water at moderate protein concentrations. Streaming potential measurements showed that adsorption reversed the net sign of the zeta potential of silica from negative to positive for all protein fractions and water hardness conditions at protein bulk concentrations as low as 0.03 MUg/mL. This suggests that sands can be effectively modified with M. oleifera proteins using small amounts of seed extract under various local water hardness conditions. Finally, ellipsometry indicated that M. oleifera proteins adsorb irreversibly with respect to rinsing in these model fresh waters, suggesting that the modified sand would be stable on repeated use for water filtration. These studies may aid in the design of a simple, effective, and sustainable water purification device for developing nations.

AB - The direct synthesis of hierarchically intergrown silicalite-1 can be achieved using a specific diquaternary ammonium agent. However, the location of these molecules in the zeolite framework, which is critical to understand the formation of the material, remains unclear. Where traditional characterization tools have previously failed, herein we use polarized stimulated Raman scattering (SRS) microscopy to resolve molecular organization inside few-micron-sized crystals. Through a combination of experiment and first-principles calculations, our investigation reveals the preferential location of the templating agent inside the linear pores of the MFI framework. Besides illustrating the attractiveness of SRS microscopy in the field of material science to study and spatially resolve local molecular distribution as well as orientation, these results can be exploited in the design of new templating agents for the preparation of hierarchical zeolites.

PMID- 29566494 TI - Tailoring the Synthesis of LnF3 (Ln = La-Lu and Y) Nanocrystals via Mechanistic Study of the Coprecipitation Method. AB - Here, 15 LnF3 nanocrystals are synthesized using coprecipitation method with citrate stabilization to allow the fast, easy, and reproducible synthesis of several nanoscaled structures in water. General trends related to the behavior of LnF3 nanocrystals are highlighted due to their broad range of application in several fields (e.g., medical applications). The same nature for all Ln3+ cations is expected due to the internal role of f orbitals. However, we found that the use of different lanthanide elements is crucial in the final size, shape, assembly, and crystalline structure. In addition, the decrease of the cation size of the lanthanide series changes the behavior of these compounds, resulting in hexagonal, orthorhombic, and cubic crystalline structures. In addition, we are able to tune the cubic crystalline phase to pure orthorhombic by modifying the pH of the system using HBF4 instead of tetramethylammonium citrate. Via 11B NMR, we demonstrated the mechanism of HBF4 as fluorinating agent if an additional source of F- is not added during the synthesis. 1H NMR and IR techniques were performed to unravel the picture of the surface chemistry of the two representative metal cations (Y and La). Finally, HRTEM and SAED were performed to uncover the shape of the obtained nanocrystals and the preferential orientation of the assembled particles, giving crucial information on the involved mechanisms. This study reveals not only the dependence of the crystalline structure on the used metal and pH but also ability to achieve LnF3 assembled particles depending on the final shape and temperature.

AB - Size-selected clusters containing a handful of atoms may possess noble catalytic properties different from nano-sized or bulk catalysts. Size- and composition selected clusters can also serve as models of the catalytic active site, where an addition or removal of a single atom can have a dramatic effect on their activity and selectivity. In this perspective, we provide an overview of studies performed under both ultra-high vacuum and realistic reaction conditions aimed at the interrogation, characterization, and understanding of the performance of supported size-selected clusters in heterogeneous and electrochemical reactions, which address the effects of cluster size, cluster composition, cluster-support interactions, and reaction conditions, the key parameters for the understanding and control of catalyst functionality. Computational modeling based on density functional theory sampling of local minima and energy barriers or ab initio molecular dynamics simulations is an integral part of this research by providing fundamental understanding of the catalytic processes at the atomic level, as well as by predicting new materials compositions which can be validated in experiments. Finally, we discuss approaches which aim at the scale up of the production of well-defined clusters for use in real world applications. PMID- 29566497 TI - Efficient sampling of reversible cross-linking polymers: Self-assembly of single chain polymeric nanoparticles. AB - We present a new simulation technique to study systems of polymers functionalized by reactive sites that bind/unbind forming reversible linkages. Functionalized polymers feature self-assembly and responsive properties that are unmatched by the systems lacking selective interactions. The scales at which the functional properties of these materials emerge are difficult to model, especially in the reversible regime where such properties result from many binding/unbinding events. This difficulty is related to large entropic barriers associated with the formation of intra-molecular loops. In this work, we present a simulation scheme that sidesteps configurational costs by dedicated Monte Carlo moves capable of binding/unbinding reactive sites in a single step. Cross-linking reactions are implemented by trial moves that reconstruct chain sections attempting, at the same time, a dimerization reaction between pairs of reactive sites. The model is parametrized by the reaction equilibrium constant of the reactive species free in solution. This quantity can be obtained by means of experiments or atomistic/quantum simulations. We use the proposed methodology to study the self assembly of single-chain polymeric nanoparticles, starting from flexible precursors carrying regularly or randomly distributed reactive sites. We focus on understanding differences in the morphology of chain nanoparticles when linkages are reversible as compared to the well-studied case of irreversible reactions. Intriguingly, we find that the size of regularly functionalized chains, in good solvent conditions, is non-monotonous as a function of the degree of functionalization. We clarify how this result follows from excluded volume interactions and is peculiar of reversible linkages and regular functionalizations. PMID- 29566498 TI - Dense colloidal mixtures in an external sinusoidal potential. AB - Concentrated binary colloidal mixtures containing particles with a size ratio 1:2.4 were exposed to a periodic potential that was realized using a light field, namely, two crossed laser beams creating a fringe pattern. The arrangement of the particles was recorded using optical microscopy and characterized in terms of the pair distribution function along the minima, the occupation probability perpendicular to the minima, the angular bond distribution, and the average potential energy per particle. The particle arrangement was investigated in dependence of the importance of particle-potential and particle-particle interactions by changing the potential amplitude and particle concentration, respectively. An increase in the potential amplitude leads to a stronger localization, especially of the large particles, but also results in an increasing fraction of small particles being located closer to the potential maxima, which also occurs upon increasing the particle density. Furthermore, increasing the potential amplitude induces a local demixing of the two particle species, whereas an increase in the total packing fraction favors a more homogeneous arrangement. PMID- 29566499 TI - Communication: Observation of ultra-slow relaxation in supercooled selenium and related glass-forming liquids. AB - The rheological behavior of supercooled Se, As10Se90, and As20Se80 liquids is studied in the linear regime as a function of frequency, extending over nearly 11 orders of magnitude, using oscillatory parallel plate rheometry. While the viscoelastic response of the As20Se80 liquid is characterized by a single relaxation time scale, the Se and the As10Se90 liquids display two distinct relaxation processes, both of which are coupled to viscosity, although their time scales differ by nearly 3-5 orders of magnitude. The ultra-slow relaxation process appears to be related to the dynamics of -Se-Se-Se- chain segments in the structure of these liquids, with characteristic time scale and shear modulus that are dependent on the average chain length. The fast mode, on the other hand, is associated with the glassy modulus and is tentatively assigned to a Johari Goldstein beta-process. These results, when taken together, are consistent with the presence of a hierarchical free energy landscape that characterizes the dynamics of the fragile Se and As10Se90 liquids.

Explicitly correlated coupled cluster singles and doubles with perturbative triples corrections: CCSD(T)-F12. AB - We present an implementation of analytical energy gradients for the explicitly correlated coupled cluster singles and doubles method with perturbative triples corrections [CCSD(T)-F12]. The accuracy of the CCSD(T)-F12 analytical gradient technique is demonstrated by computing equilibrium geometries for a set of closed shell molecules containing first- and second-row elements. Near basis-set limit equilibrium geometries are obtained with triple-zeta correlation consistent basis sets. Various approximations in the F12 treatment are compared, and the effects of these are found to be small. PMID- 29566501 TI - Morphology of size-selected Ptn clusters on CeO2(111). AB - Supported Pt catalysts and ceria are well known for their application in automotive exhaust catalysts. Size-selected Pt clusters supported on a CeO2(111) surface exhibit distinct physical and chemical properties. We investigated the morphology of the size-selected Ptn (n = 5-13) clusters on a CeO2(111) surface using scanning tunneling microscopy at room temperature. Ptn clusters prefer a two-dimensional morphology for n = 5 and a three-dimensional (3D) morphology for n >= 6. We further observed the preference for a 3D tri-layer structure when n >= 10. For each cluster size, we quantitatively estimated the relative fraction of the clusters for each type of morphology. Size-dependent morphology of the Ptn clusters on the CeO2(111) surface was attributed to the Pt-Pt interaction in the cluster and the Pt-O interaction between the cluster and CeO2(111) surface. The results obtained herein provide a clear understanding of the size-dependent morphology of the Ptn clusters on a CeO2(111) surface. PMID- 29566503 TI - Molecular-dynamics study of propane-hydrate dissociation: Fluctuation-dissipation and non-equilibrium analysis. AB - Equilibrium and non-equilibrium molecular-dynamics (MD) simulations have been performed to investigate thermal-driven break-up of planar propane-hydrate interfaces in contact with liquid water over the 260-320 K range. Two types of hydrate-surface water-lattice molecular termination were adopted, at the hydrate edge with water, for comparison: a 001-direct surface cleavage and one with completed cages. Statistically significant differences in melting temperatures and initial break-up rates were observed between both interface types. Dissociation rates were observed to be strongly dependent on temperature, with higher rates at larger over-temperatures vis-a-vis melting. A simple coupled mass and heat transfer model, developed previously, was applied to fit the observed dissociation profiles, and this helps us to identify clearly two distinct hydrate decomposition regimes; following a highly temperature-dependent break-up phase, a second well-defined stage is essentially independent of temperature, in which the remaining nanoscale, de facto two-dimensional system's lattice framework is intrinsically unstable. Further equilibrium MD-analysis of the two-phase systems at their melting point, with consideration of the relaxation times gleaned from the auto-correlation functions of fluctuations in a number of enclathrated guest molecules, led to statistically significant differences between the two surface termination cases; a consistent correlation emerged in both cases between the underlying, non-equilibrium, thermal-driven dissociation rates sampled directly from melting with that from an equilibrium-MD fluctuation-dissipation approach. PMID- 29566502 TI - The role of entropic potential in voltage activation and K+ transport through Kv 1.2 channels. AB - We analyze the entropic effects of inner pore geometry changes of Kv 1.2 channel during membrane depolarization and their implications for the rate of transmembrane transport of potassium ions. We base this on the idea that spatial confinements within the channel pore give rise to entropic barriers which can both effectively affect the stability of open macroconformation and influence channel's ability to conduct the potassium ions through the membrane. First, we calculate the differences in entropy between voltage-activated and resting states of the channel. As a template, we take a set of structures of channel pore in an open state at different membrane potentials generated in our previous research. The obtained results indicate that tendency to occupy open states at membrane depolarization is entropy facilitated. Second, we describe the differences in rates of K+ transport through the channel pore at different voltages based on the results of appropriate random walk simulations in entropic and electric potentials. The simulated single channel currents (I) suggest that the geometry changes during membrane depolarization are an important factor contributing to the observed flow of potassium ions through the channel. Nevertheless, the charge distribution within the channel pore (especially at the extracellular entrance) seems most prominent for the observed I/Imax relation at a qualitative level at analyzed voltages. PMID- 29566504 TI - Mechanism by which DHA inhibits the aggregation of KLVFFA peptides: A molecular dynamics study. AB - Docosahexaenoic acid (DHA) is one of the omega-3 polyunsaturated fatty acids, which has shown promising applications in lowering Abeta peptide neurotoxicity in vitro by preventing aggregation of Abeta peptides and relieving accumulation of Abeta fibrils. Unfortunately, the underlying molecular mechanisms of how DHA interferes with the aggregation of Abeta peptides remain largely enigmatic. Herein, aggregation behaviors of amyloid-beta(Abeta)16-21 peptides (KLVFFA) with or without the presence of a DHA molecule were comparatively studied using extensive all-atom molecular dynamics simulations. We found that DHA could effectively suppress the aggregation of KLVFFA peptides by redirecting peptides to unstructured oligomers. The highly hydrophobic and flexible nature of DHA made it randomly but tightly entangled with Leu-17, Phe-19, and Phe-20 residues to form unstructured but stable complexes. These lower-ordered unstructured oligomers could eventually pass through energy barriers to form ordered beta sheet structures through large conformational fluctuations. This study depicts a microscopic picture for understanding the role and mechanism of DHA in inhibition of aggregation of Abeta peptides, which is generally believed as one of the important pathogenic mechanisms of Alzheimer's disease. PMID- 29566505 TI - Simplified approach to the mixed time-averaging semiclassical initial value representation for the calculation of dense vibrational spectra. AB - We present and test an approximate method for the semiclassical calculation of vibrational spectra. The approach is based on the mixed time-averaging semiclassical initial value representation method, which is simplified to a form that contains a filter to remove contributions from approximately harmonic environmental degrees of freedom. This filter comes at no additional numerical cost, and it has no negative effect on the accuracy of peaks from the anharmonic system of interest. The method is successfully tested for a model Hamiltonian and then applied to the study of the frequency shift of iodine in a krypton matrix. Using a hierarchic model with up to 108 normal modes included in the calculation, we show how the dynamical interaction between iodine and krypton yields results for the lowest excited iodine peaks that reproduce experimental findings to a high degree of accuracy.

PMID- 29566507 TI - Photoinduced transport in an H64Q neuroglobin antidote for carbon monoxide poisoning. AB - Carbon monoxide (CO) is a leading cause of poisoning deaths worldwide, without available antidotal therapy. Recently, a potential treatment for CO poisoning was introduced, based on binding of CO by neuroglobin (Ngb) with a mutated distal histidine (H64Q). Here, we present an atomistic mechanism of CO trapping by H64Q Ngb revealed by nonadiabatic molecular dynamics. We focused on CO photodissociation and recombination of CO to wild type (WT) and H64Q Ngb. Our results demonstrate that the distribution of CO within the proteins differs substantially due to rearrangement of amino acids surrounding the distal heme pocket. This leads to the decrease of the distal pocket volume in H64Q Ngb in comparison to WT Ngb, trapping migrating CO molecules in the distal pocket. We show that the mutation implicates the shortening of the time scale of CO geminate recombination, making H64Q Ngb 2.7 times more frequent binder than WT Ngb. PMID- 29566508 TI - Weak polyelectrolyte complexation driven by associative charging. AB - Weak polyelectrolytes are relevant for a wide range of fields; in particular, they have been investigated as "smart" materials for chemical separations and drug delivery. The charges on weak polyelectrolytes are dynamic, causing polymer chains to adopt different equilibrium conformations even with relatively small changes to the surrounding environment. Currently, there exists no comprehensive picture of this behavior, particularly where polymer-polymer interactions have the potential to affect charging properties significantly. In this study, we elucidate the novel interplay between weak polyelectrolyte charging and complexation behavior through coupled molecular dynamics and Monte Carlo simulations. Specifically, we investigate a model of two equal-length and oppositely charging polymer chains in an implicit salt solution represented through Debye-Huckel interactions. The charging tendency of each chain, along with the salt concentration, is varied to determine the existence and extent of cooperativity in charging and complexation. Strong cooperation in the charging of these chains is observed at large Debye lengths, corresponding to low salt concentrations, while at lower Debye lengths (higher salt concentrations), the chains behave in apparent isolation. When the electrostatic coupling is long ranged, we find that a highly charged chain strongly promotes the charging of its partner chain, even if the environment is unfavorable for an isolated version of that partner chain. Evidence of this phenomenon is supported by a drop in the potential energy of the system, which does not occur at the lower Debye lengths where both potential energies and charge fractions converge for all partner chain charging tendencies. The discovery of this cooperation will be helpful in developing "smart" drug delivery mechanisms by allowing for better predictions for the dissociation point of delivery complexes.

AB - The quest of an exact and nonperturbative treatment of quantum dissipation in nonlinear coupling environments remains in general an intractable task. In this work, we address the key issues toward the solutions to the lowest nonlinear environment, a harmonic bath coupled both linearly and quadratically with an arbitrary system. To determine the bath coupling descriptors, we propose a physical mapping scheme, together with the prescription reference invariance requirement. We then adopt a recently developed dissipaton equation of motion theory [R. X. Xu et al., Chin. J. Chem. Phys. 30, 395 (2017)], with the underlying statistical quasi-particle ("dissipaton") algebra being extended to the quadratic bath coupling. We report the numerical results on a two-level system dynamics and absorption and emission line shapes. PMID- 29566510 TI - The coexistence temperature of hydrogen clathrates: A molecular dynamics study. AB - Extensive molecular dynamics simulations in the equilibrium isobaric-isothermal (NPT) ensemble were developed to determine the coexistence temperatures of the water hydrogen mixture using the direct coexistence method. The water molecules were modeled using the four-site TIP4P/Ice analytical potential, and the hydrogen molecules were described using a three-site potential. The simulations were performed at different pressures (p = 900, 1500, 3000, and 4000 bars). At each pressure, a series of simulations were developed at different temperatures (from 230 to 270 K). Our results followed a line parallel to the experimental coexistence temperatures and underestimated these temperatures by approximately 25 K in the investigated range. The final configurations could or could not contain a fluid phase depending on the pressure, in accordance with the phase diagram. In addition, we explored the dynamics of the H2 molecules through clathrate hydrate cages and observed different behaviors of the H2 molecules in the small cages and the large cages of the sII structure.

AB - It is shown that in isothermal isobaric diffusion of a binary fluid mixture, the mean volume velocity vanishes in the linear regime, independent of the equation of state. The partial specific volumes of the two components are uniform and constant in the process of mutual diffusion. The properties lead to a simple derivation of the de Groot-Mazur thermodynamic factor in the diffusion coefficient. The properties also imply that the diffusive volume flux defined by Brenner is proportional to the mass current density, and is therefore not a quantity of independent interest. PMID- 29566513 TI - Cavitation transition in the energy landscape: Distinct tensile yielding behavior in strongly and weakly attractive systems. AB - Particles with cohesive interactions display a tensile instability in the energy landscape at the Sastry density rhoS. The signature of this tensile limit is a minimum in the landscape equation of state, the pressure-density relationship of inherent structures sampled along a liquid isotherm. Our previous work [Y. E. Altabet, F. H. Stillinger, and P. G. Debenedetti, J. Chem. Phys. 145, 211905 (2016)] revisited the phenomenology of Sastry behavior and found that the evolution of the landscape equation of state with system size for particles with interactions typical of molecular liquids indicates the presence of an athermal first-order phase transition between homogeneous and fractured inherent structures, the latter containing several large voids. Here, we study how this tensile limit manifests itself for different interparticle cohesive strengths and identify two distinct regimes. Particles with sufficiently strong cohesion display an athermal first-order phase transition, consistent with our prior characterization. Weak cohesion also displays a tensile instability. However, the landscape equation of state for this regime is independent of system size, suggesting the absence of a first-order phase transition. An analysis of the voids suggests that yielding in the energy landscape of weakly cohesive systems is associated with the emergence of a highly interconnected network of small voids. While strongly cohesive systems transition from exclusively homogeneous to exclusively fractured configurations at rhoS in the thermodynamic limit, this interconnected network develops gradually, starting at rhoS, even at infinite system size. PMID- 29566514 TI - An efficient zero-order description of the fine structure in the infrared reflection band of cubic ionic crystals and the phonon-polariton dispersion using Lorentz gauge. AB - The reflection of infrared light by ionic crystals with cubic symmetry such as lithium fluoride, LiF, is analyzed in terms of phonon-polaritons. In contrast to the conventional view on phonon-polaritons that uses the Coulomb gauge and assumes a purely local dielectric response of the material, we here develop an alternative description making use of the Lorentz gauge. This involves retarded interactions between charges, implying a non-local response of the material to electromagnetic radiation. The resulting new phonon-polariton dispersion relation features polaritons with negative group velocity in the frequency range in between the transverse (omegaT) and longitudinal frequency (omegaL). By contrast, the conventional description predicts, in zero order, the absence of any propagating polaritons in the frequency interval between omegaT and omegaL. The new dispersion relation provides an efficient, zero-order description of the fine structure within the reststrahlen band of LiF. The local minimum near the middle of the reflectance band is due to excitation of a phonon-polariton whose energy and momentum matches that of the incoming photon. The Lorentz gauge description can also describe off-normal reflection and accounts for the experimentally observed widening of the reflection band with increasing angle of incidence. PMID- 29566515 TI - Improved local lattice Monte Carlo simulation for charged systems. AB - Maggs and Rossetto [Phys. Rev. Lett. 88, 196402 (2002)] proposed a local lattice Monte Carlo algorithm for simulating charged systems based on Gauss's law, which scales with the particle number N as O(N). This method includes two degrees of freedom: the configuration of the mobile charged particles and the electric field. In this work, we consider two important issues in the implementation of the method, the acceptance rate of configurational change (particle move) and the ergodicity in the phase space sampled by the electric field. We propose a simple method to improve the acceptance rate of particle moves based on the superposition principle for electric field. Furthermore, we introduce an additional updating step for the field, named "open-circuit update," to ensure that the system is fully ergodic under periodic boundary conditions. We apply this improved local Monte Carlo simulation to an electrolyte solution confined between two low dielectric plates. The results show excellent agreement with previous theoretical work.

We present techniques to accommodate the singular nature of idealized nuclear and idealized electronic potentials, and we demonstrate the utility of using high order accurate grid based approximations to Poisson's equation in unbounded domains. To demonstrate the accuracy of these techniques, we present results for a Full Configuration Interaction computation of the dissociation of H2 using a computed, configuration dependent, orbital basis set. PMID- 29566517 TI - Variational nonadiabatic dynamics in the moving crude adiabatic representation: Further merging of nuclear dynamics and electronic structure. AB - A new methodology of simulating nonadiabatic dynamics using frozen-width Gaussian wavepackets within the moving crude adiabatic representation with the on-the-fly evaluation of electronic structure is presented. The main feature of the new approach is the elimination of any global or local model representation of electronic potential energy surfaces; instead, the electron-nuclear interaction is treated explicitly using the Gaussian integration. As a result, the new scheme does not introduce any uncontrolled approximations. The employed variational principle ensures the energy conservation and leaves the number of electronic and nuclear basis functions as the only parameter determining the accuracy. To assess performance of the approach, a model with two electronic and two nuclear spacial degrees of freedom containing conical intersections between potential energy surfaces has been considered. Dynamical features associated with nonadiabatic transitions and nontrivial geometric (or Berry) phases were successfully reproduced within a limited basis expansion.

AB - This article proposes a gauge-origin independent formalism of the nuclear magnetic shielding constant in the two-component relativistic framework based on the unitary transformation. The proposed scheme introduces the gauge factor and the unitary transformation into the atomic orbitals. The two-component relativistic equation is formulated by block-diagonalizing the Dirac Hamiltonian together with gauge factors. This formulation is available for arbitrary relativistic unitary transformations. Then, the infinite-order Douglas-Kroll-Hess (IODKH) transformation is applied to the present formulation. Next, the analytical derivatives of the IODKH Hamiltonian for the evaluation of the nuclear magnetic shielding constant are derived. Results obtained from the numerical assessments demonstrate that the present formulation removes the gauge-origin dependence completely. Furthermore, the formulation with the IODKH transformation gives results that are close to those in four-component and other two-component relativistic schemes.

Within a model of like-charged mixtures of particles governed by effective electrostatic interactions, we explore the influence of charged nanoparticles on the structure and thermodynamic phase stability of charge stabilized colloidal suspensions. Focusing on salt-free mixtures of particles of high size and charge asymmetry, interacting via repulsive Yukawa effective pair potentials, we perform molecular dynamics simulations and compute radial distribution functions and static structure factors. Analysis of these structural properties indicates that increasing the charge and concentration of nanoparticles progressively weakens correlations between charged colloids. We show that addition of charged nanoparticles to a suspension of like-charged colloids can induce a colloidal crystal to melt and can facilitate aggregation of a fluid suspension due to attractive van der Waals interactions. We attribute the destabilizing influence of charged nanoparticles to enhanced screening of electrostatic interactions, which weakens repulsion between charged colloids. This interpretation is consistent with recent predictions of an effective interaction theory of charged colloid-nanoparticle mixtures. PMID- 29566520 TI - Comprehensive representation of the Lennard-Jones equation of state based on molecular dynamics simulation data. AB - The equation of state (EoS) of the Lennard-Jones fluid is calculated using a new set of molecular dynamics data which extends to higher temperature than in previous studies. The modified Benedict-Webb-Rubin (MBWR) equation, which goes up to ca. T ~ 6, is reparametrized with new simulation data. A new analytic form for the EoS, which breaks the fluid range into two regions with different analytic forms and goes up to ca. T ? 35, is also proposed. The accuracy of the new formulas is at least as good as the MBWR fit and goes to much higher temperature allowing it to now encompass the Amagat line. The fitted formula extends into the high temperature range where the system can be well represented by inverse power potential scaling, which means that our specification of the equation of state covers the entire (rho, T) plane. Accurate analytic fit formulas for the Boyle, Amagat, and inversion curves are presented. Parametrizations of the extrema loci of the isochoric, CV, and isobaric, CP, heat capacities are given. As found by others, a line maxima of CP terminates in the critical point region, and a line of minima of CP terminates on the freezing line. The line of maxima of CV terminates close to or at the critical point, and a line of minima of CV terminates to the right of the critical point. No evidence for a divergence in CV in the critical region is found.

AB - Vibrational levels (v = 6-42) of the NaH C 1Sigma+ state including the inner and outer wells and the near-dissociation region were observed by pulsed optical optical double resonance fluorescence depletion spectroscopy. The absolute vibrational quantum number is identified by comparing the vibrational energy difference of this experiment with the ab initio calculations. The outer well with v up to 34 is analyzed using the Dunham expansion and a Rydberg-Klein-Rees (RKR) potential energy curve is constructed. A hybrid double-well potential combined with the RKR potential, the ab initio calculation, and a long-range potential is able to describe the whole NaH C 1Sigma+ state including the higher vibrational levels (v = 35-42). The dissociation energy of the NaH C 1Sigma+ state is determined to be De(C) = 6595.10 +/- 5 cm-1 and then the dissociation energy of the NaH ground state De(X) = 15 807.87 +/- 5 cm-1 can be derived.

AB - Electrostatic levitation is applied in order to undercool liquid glass forming NiZr significantly below its melting temperature. For NiZr large undercoolings are found to be highly reproducible with this experimental method. One single NiZr sample of high purity is undercooled 200 consecutive times which leads to a distribution function of undercooling temperatures. Within a statistical approach of classical nucleation theory, the undercooling distribution is analyzed yielding parameters, e.g., a pre-exponential factor of KV ~ 1035 m-3 s-1, which indicates homogeneous nucleation. This result is consistent with the crystallization behavior of NiZr at high undercooling and with the corresponding microstructural analysis. Since NiZr is a representative of the very common CrB structure type, with 132 isostructural phases existing, understanding its nucleation behavior adds important knowledge to the nucleation of binary alloys in general.

AB - We propose a systematic formulation of the migration behaviors of a vesicle in a Poiseuille flow based on Onsager's variational principle, which can be used to determine the most stable steady state. Our model is described by a combination of the phase field theory for the vesicle and the hydrodynamics for the flow field. The dynamics is governed by the bending elastic energy and the dissipation functional, the latter being composed of viscous dissipation of the flow field, dissipation of the bending energy of the vesicle, and the friction between the vesicle and the flow field. We performed a series of simulations on 2-dimensional systems by changing the bending elasticity of the membrane and observed 3 types of steady states, i.e., those with slipper shape, bullet shape, and snaking motion, and a quasi-steady state with zig-zag motion. We show that the transitions among these steady states can be quantitatively explained by evaluating the dissipation functional, which is determined by the competition between the friction on the vesicle surface and the viscous dissipation in the bulk flow. PMID- 29566524 TI - Structure of the first order reduced density matrix in three electron systems: A generalized Pauli constraints assisted study. AB - We investigate the structure of the one-body reduced density matrix of three electron systems, i.e., doublet and quadruplet spin configurations, corresponding to the smallest interacting system with an open-shell ground state. To this end, we use configuration interaction (CI) expansions of the exact wave function in Slater determinants built from natural orbitals in a finite dimensional Hilbert space. With the exception of maximally polarized systems, the natural orbitals of spin eigenstates are generally spin dependent, i.e., the spatial parts of the up and down natural orbitals form two different sets. A measure to quantify this spin dependence is introduced and it is shown that it varies by several orders of magnitude depending on the system. We also study the ordering issue of the spin dependent occupation numbers which has practical implications in reduced density matrix functional theory minimization schemes, when generalized Pauli constraints (GPCs) are imposed and in the form of the CI expansion in terms of the natural orbitals. Finally, we discuss the aforementioned CI expansion when there are GPCs that are almost "pinned."

AB - Although three-dimensional site-site molecular integral equations of liquids are a powerful tool of the modern theoretical chemistry, their applications to the problem of characterizing the electrical double layer originating at the solid liquid interface with a macroscopic substrate are severely limited by the fact that an infinitely extended charged plane generates a divergent electrostatic potential. Such potentials cannot be treated within the standard 3D-Reference Interaction Site Model equation solution framework since it leads to functions that are not Fourier transformable. In this paper, we apply a renormalization procedure to overcome this obstacle. We then check the validity and numerical accuracy of the proposed computational scheme on the prototypical gold (111) surface in contact with water/alkali chloride solution. We observe that despite the proposed method requires, to achieve converged charge densities, a higher spatial resolution than that suited to the estimation of biomolecular solvation with either 3D-RISM or continuum electrostatics approaches, it still is computationally efficient. Introducing the electrostatic potential of an infinite wall, which is periodic in 2 dimensions, we avoid edge effects, permit a robust integration of Poisson's equation, and obtain the 3D electrostatic potential profile for the first time in such calculations. We show that the potential within the electrical double layer presents oscillations which are not grasped by the Debye-Huckel and Gouy-Chapman theories. This electrostatic potential deviates from its average of up to 1-2 V at small distances from the substrate along the lateral directions. Applications of this theoretical development are relevant, for example, for liquid scanning tunneling microscopy imaging.

AB - Propylene oxide, a favorite target of experimental and theoretical studies of circular dichroism, was recently discovered in interstellar space, further amplifying the attention to its role in the current debate on protobiological homochirality. In the present work, a photoelectron-photoion-photoion coincidence technique, using an ion-imaging detector and tunable synchrotron radiation in the 18.0-37.0 eV energy range, permits us (i) to observe six double ionization fragmentation channels, their relative yields being accounted for about two thirds by the couple (C2H4+, CH2O+) and one-fifth by (C2H3+, CH3O+); (ii) to measure thresholds for their openings as a function of photon energy; and (iii) to unravel a pronounced bimodality for a kinetic-energy-released distribution, fingerprint of competitive non-adiabatic mechanisms.

AB - We investigated a set of nineteen 12C16O2 transitions of the 2nu1 + nu3 ro vibrational band in the spectral region from 5064 to 5126 cm-1 at different pressures, using frequency-comb Vernier spectroscopy. Our spectrometer enabled the systematic acquisition of molecular absorption profiles with high precision. Spectroscopic parameters, namely, transition frequency, linestrength, and self pressure broadening coefficient, have been accurately determined by using a global fit procedure. These data are in agreement with theoretical values contained in HITRAN2016 database [I. E. Gordon et al., J. Quant. Spectrosc. Radiat. Transfer 203, 3-69 (2017)] at the same precision level. A moderate improvement of the line intensity determinations, by a factor 1.5 in the best case [P(10) transition at 5091.6 cm-1], should be noticed, projecting direct-comb Vernier-spectroscopy as an adequate tool for spectral intensity calibration.

AB - The interfaces between organic molecules and magnetic metals have gained increasing interest for both fundamental reasons and applications. Among them, the C60/layered antiferromagnetic (AFM) interfaces have been studied only for C60 bonded to the outermost ferromagnetic layer [S. L. Kawahara et al., Nano Lett. 12, 4558 (2012) and D. Li et al., Phys. Rev. B 93, 085425 (2016)]. Here, via density functional theory calculations combined with evidence from the literature, we demonstrate that C60 adsorption can reconstruct the layered-AFM Cr(001) surface at elevated annealing temperatures so that C60 bonds to both the outermost and the subsurface Cr layers in opposite spin directions. Surface reconstruction drastically changes the adsorbed molecule spintronic properties: (1) the spin-split p-d hybridization involves multi-orbitals of C60 and top two layers of Cr with opposite spin-polarization, (2) the subsurface Cr atom dominates the C60 electronic properties, and (3) the reconstruction induces a large magnetic moment of 0.58 MUB in C60 as a synergistic effect of the top two Cr layers. The induced magnetic moment in C60 can be explained by the magnetic direct-exchange mechanism, which can be generalized to other C60/magnetic metal systems. Understanding these complex hybridization behaviors is a crucial step for molecular spintronic applications. PMID- 29566529 TI - Heterogeneous nucleation of a droplet pinned at a chemically inhomogeneous substrate: A simulation study of the two-dimensional Ising case. AB - Heterogeneous nucleation is studied by Monte Carlo simulations and phenomenological theory, using the two-dimensional lattice gas model with suitable boundary fields. A chemical inhomogeneity of length b at one boundary favors the liquid phase, while elsewhere the vapor is favored. Switching on the bulk field Hb favoring the liquid, nucleation and growth of the liquid phase starting from the region of the chemical inhomogeneity are analyzed. Three regimes occur: for small fields, HbHb*), the droplets nucleated at the chemical inhomogeneity grow to the full system size. While the relaxation time for the growth scales as tauG?Hb-1, the nucleation time tauN scales as lntauN?Hb-1. However, the prefactor in the latter relation, as evaluated for our simulations results, is not in accord with an extension of the Volmer-Turnbull theory to two-dimensions, when the theoretical contact angle thetac is used. PMID- 29566530 TI - Three-beam double stimulated Raman scatterings: Cascading configuration. AB - Two-beam stimulated Raman scattering (SRS) has been used in diverse label-free spectroscopy and imaging applications of live cells, biological tissues, and functional materials. Recently, we developed a theoretical framework for the three-beam double SRS processes that involve pump, Stokes, and depletion beams, where the pump-Stokes and pump-depletion SRS processes compete with each other. It was shown that the net Stokes gain signal can be suppressed by increasing the depletion beam intensity. The theoretical prediction has been experimentally confirmed recently. In the previous scheme for a selective suppression of one SRS by making it compete with another SRS, the two SRS processes occur in a parallel manner. However, there is another possibility of three-beam double SRS scheme that can be of use to suppress either Raman gain of the Stokes beam or Raman loss of the pump beam by depleting the Stokes photons with yet another SRS process induced by the pair of Stokes and another (second) Stokes beam. This three-beam double SRS process resembles a cascading energy transfer process from the pump beam to the first Stokes beam (SRS-1) and subsequently from the first Stokes beam to the second Stokes beam (SRS-2). Here, the two stimulated Raman gain-loss processes are associated with two different Raman-active vibrational modes of solute molecule. In the present theory, both the radiation and the molecules are treated quantum mechanically. We then show that the cascading-type three-beam double SRS can be described by coupled differential equations for the photon numbers of the pump and Stokes beams. From the approximate solutions as well as exact numerical calculation results for the coupled differential equations, a possibility of efficiently suppressing the stimulated Raman loss of the pump beam by increasing the second Stokes beam intensity is shown and discussed. To further prove a potential use of this scheme for developing a super-resolution SRS microscopy, we present a theoretical expression and numerical simulation results for the full-width-at-half-maximum of SRS imaging point spread function, assuming that the pump and Stokes beam profiles are Gaussian and the second Stokes beam has a doughnut-shaped spatial profile. It is clear that the spatial resolution with the present 3-beam cascading SRS method can be enhanced well beyond the diffraction limit. We anticipate that the present work will provide a theoretical framework for a super-resolution stimulated Raman scattering microscopy that is currently under investigation. PMID- 29566531 TI - Collective excitations and ultrafast dipolar solvation dynamics in water-ethanol binary mixture. AB - In order to understand the intermolecular vibrational spectrum and the collective excitations of water-ethanol binary mixture, we investigate the density of states and the power spectrum using computer simulations aided by theory. We investigate in particular the spectra at intermediate to low frequencies (a few hundreds to few tens of cm-1) by calculating (i) the density of states from quenched normal modes, (ii) the power spectrum from velocity time correlation function, and (iii) the far infrared and dielectric spectra (that is, the Cole-Cole plot) from the total dipole moment time correlation function. The different spectra are in broad agreement with each other and at the same time reveal unique characteristics of the water-ethanol mixture. Inverse participation ratio reveals several interesting features. Libration of pure ethanol is more localized than that of pure water. With increasing ethanol content, we observe localization of the collective libration mode as well as of the hindered translational and rotational mode. An interesting mixing between the libration of water and ethanol is observed. Solvation dynamics of tryptophan measured by equilibrium energy fluctuation time correlation function show surprisingly strong non-linear dependence on composition that can be tested against experiments.

AB - Dilute solutions of sodium poly(styrene sulfonate) (NaPSS) in the presence of Al3+, Ca2+, and Ba2+ were analysed by means of isothermal titration calorimetry (ITC) in order to investigate the heat effect of bond formation between those cations and the anionic SO3- residues of NaPSS. The selection of the cations was guided by the solution behavior of the corresponding PSS salts from a preceding study [M. Hansch et al., J. Chem. Phys. 148(1), 014901 (2018)], where bonds between Ba2+ and anionic PSS showed an increasing solubility with decreasing temperature and Al3+ exhibited the inverse trend. Unlike to Al3+ and Ba2+, Ca2+ is expected to behave as a purely electrostatically interacting bivalent cation and was thus included in the present study. Results from ITC satisfactorily succeeded to explain the temperature-dependent solution behavior of the salts with Al3+ and Ba2+ and confirmed the non-specific behavior of Ca2+. Additional ITC experiments with salts of Ca2+ and Ba2+ and sodium poly(acrylate) complemented the results on PSS by data from a chemically different polyanion. Availability of these joint sets of polyanion-cation combinations not only offers the chance to identify common features and subtle differences in the solution behavior of polyelectrolytes in the presence of multi-valent cations but also points to a new class of responsive materials. PMID- 29566533 TI - Penning ionization widths by Fano-algebraic diagrammatic construction method. AB - We present an ab initio theory and computational method for Penning ionization widths. Our method is based on the Fano theory of resonances, algebraic diagrammatic construction (ADC) scheme for many-electron systems, and Stieltjes imaging procedure. It includes an extension of the Fano-ADC scheme [V. Averbukh and L. S. Cederbaum, J. Chem. Phys. 123, 204107 (2005)] to triplet excited states. Penning ionization widths of various He*-H2 states are calculated as a function of the distance R between He* and H2. We analyze the asymptotic (large R) dependences of the Penning widths in the region where the well-established electron transfer mechanism of the decay is suppressed by the multipole- and/or spin-forbidden energy transfer. The R-12 and R-8 power laws are derived for the asymptotes of the Penning widths of the singlet and triplet excited states of He*(1s2s1,3S), respectively. We show that the electron transfer mechanism dominates Penning ionization of He*(1s2s 3S)-H2 up until the He*-H2 separation is large enough for the radiative decay of He* to become the dominant channel. The same mechanism also dominates the ionization of He*(1s2s 1S)-H2 when R < 5 A. We estimate that the regime of energy transfer in the He*-H2 Penning ionization cannot be reached by approaching zero collisional temperature. However, the multipole-forbidden energy transfer mechanism can become important for Penning ionization in doped helium droplets. PMID- 29566534 TI - Updates in Stroke Care. PMID- 29566535 TI - "You Want Your Guests to Be Happy in This Business": Hoteliers' Decisions to Adopt Voluntary Smoke-Free Guest-Room Policies. AB - PURPOSE:: To explore why some hotels have implemented 100% smoke-free policies voluntarily, the perceived consequences of doing so, and media responses. DESIGN:: Qualitative study of hotel management and quantitative content analysis of media coverage of smoke-free hotels. SETTING:: Hotels and media based in the United States. PARTICIPANTS:: Eleven representatives of 5 independent and 4 chain hotels. Other data included 265 news items about smoke-free hotels. METHOD:: We conducted 30-minute semi-structured interviews with hotel representatives and analyzed the data using qualitative content analysis. We also searched 3 online news databases for news items about hotels in our study, and collaboratively coded retrieved items; we analyzed the content and slant of news items. RESULTS:: Business considerations, including guest requests, competitor action, and cost savings, were the primary motivations for implementing 100% smoke-free guest-room policies. Health concerns played a minimal role. Hotels received positive feedback from customers and employees. Media coverage was favorable, emphasizing positive aspects of going smoke-free; the overall slant of news items was positive or neutral. However, few hotels marketed the change. CONCLUSIONS:: Since hotel customers and employees are likely to experience long periods of smoke exposure and smoke-free hotels appear to be so well received, it may be timely to pursue policies making all hotels smoke-free. PMID- 29566536 TI - Trends in Cigarette Advertising, Price-Reducing Promotions, and Policy Compliance in New York State Licensed Tobacco Retailers, 2004 to 2015. AB - PURPOSE:: To describe the presence of licensed tobacco retailers (LTRs), cigarette advertisements, price-reducing promotions, and compliance with tobacco control policies in New York State from 2004 to 2015 and to discuss implications and lessons learned from 11 years of experience conducting LTR surveys. DESIGN:: Annual surveys of tobacco advertising from cross-sectional, stratified random samples of LTRs in New York State from 2004 to 2015 were conducted by professional data collectors. Data for 2013 were unavailable as the survey was not fielded in that year. SETTING:: New York State. PARTICIPANTS:: Licensed tobacco retailers, which are stores licensed to sell tobacco in the state of New York. Between 3.6% (n = 800) and 19.7% (n = 3945) of all LTRs were sampled annually. MEASURES:: The presence and number of cigarette advertisements and the presence of price-reducing promotions, required age-of-sale signage, and self service tobacco displays were documented. ANALYSIS:: We tested for significant differences between 2014 and 2015 and significant trends overall and by outlet type. We used logistic regression for binary outcomes and Poisson regression for count variables. RESULTS:: The number of LTRs in New York State decreased 22.9% from 2004 (n = 25 740) to 2015 (n = 19 855). The prevalence and number of cigarette advertisements and the prevalence of cigarette price-reducing promotions decreased significantly over time. Compliance with posting required age-of-sale signs increased significantly from 2004 to 2015 and from 2014 to 2015. Compliance with the ban on self-service tobacco displays was consistently near 100%. CONCLUSION:: The tobacco retail environment in New York State improved substantially from 2004 to 2015. The implications of these findings for youth and adult smoking and the associated social costs are unknown; however, decreases in pro-tobacco marketing, decreases in the number of LTRs, and improvements in compliance are likely to have positive impacts on youth and adult smoking outcomes, such as reduced initiation and increased cessation, given previous research findings.

AB - PURPOSE: To assess the effectiveness of autologous platelet-rich plasma for the treatment of dormant corneal ulcers secondary to corneal surgery and unresponsive to conventional treatment. SETTING: VISSUM, Ophthalmology Institute of Alicante, Alicante, Spain. DESIGN: Prospective nonrandomized, observational consecutive study. METHODS: A total of 44 eyes of 28 patients with dormant corneal ulcers secondary to corneal surgery were included in a prospective study and treated with autologous platelet-rich plasma during 6 weeks. Wilcoxon signed-rank test was used to compare the effect of the treatment. RESULTS: In all, 28 patients (65.1%) improved their visual acuity at least one line in Snellen chart, 26 (59.09%) had a decrease in the size of the ulcer or even a total closure, and 40 (90.9%) experienced an improvement in their symptoms. The results are also provided for the four groups of patients (keratoplasty, refractive surgery, cross linking, and chronic postsurgical corneal edema). CONCLUSION: Platelet-rich plasma eye drops shows to be a good option for the treatment of dormant corneal ulcers secondary to corneal surgery. PMID- 29566538 TI - Frequent cross-resistance to rilpivirine among subtype C HIV-1 from first-line antiretroviral therapy failures in South Africa. AB - Background Rilpivirine (TMC278LA) is a promising drug for pre-exposure prophylaxis of HIV-1 because of its sub-nanomolar potency and long-acting formulation; however, increasing transmission of non-nucleoside reverse transcriptase inhibitor-resistant HIV-1 with potential cross-resistance to rilpivirine could reduce its preventive efficacy. This study investigated rilpivirine cross-resistance among recombinant subtype C HIV-1 derived from 100 individuals failing on first-line non-nucleoside reverse transcriptase inhibitor containing antiretroviral therapy in South Africa whose samples were sent for routine HIV-1 drug resistance testing to Lancet Laboratories (Johannesburg, South Africa). Methods Plasma samples were selected from individuals with HIV-1 RNA > 10,000 copies/ml and >=1 non-nucleoside reverse transcriptase inhibitor resistance mutation in reverse transcriptase. Recombinant HIV-1LAI-containing bulk-cloned full-length reverse transcriptase sequences from plasma were assayed for susceptibility to nevirapine (NVP), efavirenz (EFV) and rilpivirine in TZM-bl cells. Fold-change (FC) decreases in drug susceptibility were calculated against a mean IC50 from 12 subtype C HIV-1 samples from treatment-naive individuals in South Africa. Cross-resistance was evaluated based on biological cutoffs established for rilpivirine (2.5-FC) and the effect of mutation combinations on rilpivirine phenotype. Results Of the 100 samples from individuals on failing antiretroviral therapy, 69 had 2.5- to 75-fold decreased susceptibility to rilpivirine and 11 had >75-fold resistance. Rilpivirine resistance was strongly associated with K103N especially in combination with other rilpivirine-associated mutations. Conclusion The frequently observed cross-resistance of HIV-1 suggests that the preventive efficacy of TMC278LA pre-exposure prophylaxis could be compromised by transmission of HIV-1 from individuals with failure of first-line non-nucleoside reverse transcriptase inhibitor-containing antiretroviral therapy. PMID- 29566540 TI - Molecular studies of CGRP and the CGRP family of peptides in the central nervous system. AB - Background Calcitonin gene-related peptide is an important target for migraine and other painful neurovascular conditions. Understanding the normal biological functions of calcitonin gene-related peptide is critical to understand the mechanisms of calcitonin gene-related peptide-blocking therapies as well as engineering improvements to these medications. Calcitonin gene-related peptide is closely related to other peptides in the calcitonin gene-related peptide family of peptides, including amylin. Relatedness in peptide sequence and in receptor biology makes it difficult to tease apart the contributions that each peptide and receptor makes to physiological processes and to disorders. Summary The focus of this review is the expression of calcitonin gene-related peptide, related peptides and their receptors in the central nervous system. Calcitonin gene related peptide is expressed throughout the nervous system, whereas amylin and adrenomedullin have only limited expression at discrete sites in the brain. The components of two receptors that respond to calcitonin gene-related peptide, the calcitonin gene-related peptide receptor (calcitonin receptor-like receptor with receptor activity-modifying protein 1) and the AMY1 receptor (calcitonin receptor with receptor activity-modifying protein 1), are expressed throughout the nervous system. Understanding expression of the peptides and their receptors lays the foundation for more deeply understanding their physiology, pathophysiology and therapeutic use.

AB - PURPOSE: To evaluate light and electron microscopic changes of the anterior capsule and its epithelium after clear lens extraction of vitrectomized myopic eyes with silicone oil tamponade. METHODS: This prospective, controlled, non randomized, interventional study included 20 anterior lens capsular specimens that were excised during combined clear lens extraction and silicone oil removal from previously vitrectomized highly myopic patients with silicone oil tamponade for previous retinal detachment surgeries. The specimens were examined via light microscopy and electron microscopy and compared with 20 anterior capsule specimens removed during clear lens extraction of non-vitrectomized highly myopic eyes. RESULTS: Light microscopic examination of clear lens anterior capsule specimens of vitrectomized myopic eyes filled with silicone oil showed relatively more flat cells with irregular outline of lens' epithelial cells with wide intercellular spaces, deeply stained nuclei, and multiple intracytoplasmic vacuoles. Scanning electron microscopy revealed collagenous surfaces filled with multiple pits, depressions, and abnormal deposits. Transmission electron microscopy revealed lens epithelial cells with apoptotic changes, many cytoplasmic vacuoles, and filopodia-like protrusions between lens epithelial cells and the capsule. Epithelial proliferation and multilayering were also observed. CONCLUSION: silicone oil may play a role in the development of apoptotic and histopathological changes in clear lens epithelial cells. Clarity of the lens at the time of silicone oil removal does not indicate an absence of cataractous changes. We found justification of combined clear lens extraction and silicone oil removal or combined phacovitrectomy when silicone oil injection is planned, but further long-term studies with larger patient groups are required. PMID- 29566541 TI - Advance care planning for people with dementia: Ordinary everyday conversations. AB - Advance care planning for people with dementia has become a focus of dementia care policies in developed countries. In New Zealand, the framework for dementia care relies on the person with dementia having a level of competence to enable them to participate in the planning process. For people with dementia, it may be too late to initiate these discussions in terms of decision-making capacity. Consequently, decisions about end-of-life care for people with dementia are typically made by a family member who acts as a surrogate decision maker on behalf of the person with dementia. An exploratory qualitative study of 23 people who had been carers or provided support for a family member with dementia who had died within five years of the interview was undertaken. The overarching theme, 'ordinary everyday conversations', describes how informal conversations and discussions within the family relating to preferences at the end of life had been embedded in interactions within the families over years. Sub-themes revealed three important components enabling adherence to the prior wishes of the person with dementia through these conversations: knowing the person and belief in 'doing the right thing'; the importance of Wills and Enduring Power of Attorney; and negotiating unexpected encounters. There is potential for families to be well prepared for the time when they may need to make decisions for the person with dementia based on ordinary everyday conversation that take place within families and throughout life. This study also suggests that more innovative approaches to making a Will may provide an important vehicle for expressing advanced care wishes. PMID- 29566542 TI - Comparative evaluation of Scheimpflug tomography parameters between thin non keratoconic, subclinical keratoconic, and mild keratoconic corneas. AB - PURPOSE: To evaluate and compare the topographic and topometric parameters, thickness profile data, and data from enhanced elevation maps of thin non keratoconic, subclinical keratoconic, and mild keratoconic corneas with the Pentacam Scheimpflug corneal tomography and to study the usefulness of different parameters to differentiate keratoconus from topographically normal thin corneas. METHODS: The study included 30 eyes with subclinical keratoconus, 30 eyes with mild-stage keratoconus, and 54 healthy eyes with minimal pachymetry <=500 um, with a mean age of 21.19 +/- 2.97, 21.75 +/- 1.93, and 21.5 +/- 2.95 years, respectively. The area under the receiver operating characteristic curves was used to analyze the diagnostic significance of the Pentacam parameters. RESULTS: The anterior and posterior corneal elevations, pachymetric progression, the percentage of thickness increase measurements, overall D value, and topometric indices were statistically significantly higher in subclinical and mild keratoconic corneas than in normal eyes with thin cornea (p < 0.05). All these parameters had sufficient strength (area under the receiver operating characteristic curves >0.90) to differentiate clinical keratoconus. Posterior elevation showed the excellent area under the receiver operating characteristic curves with 100% sensitivity and 100% specificity for this purpose. However, among all parameters studied, the anterior elevation (0.935) showed the excellent area under the receiver operating characteristic curves to differentiate subclinical keratoconus, followed by posterior elevation (0.897), index of height decentration (0.887), and D value (0.882). CONCLUSION: The parameters derived from the Scheimpflug device, such as corneal elevations and overall D value, can effectively differentiate subclinical and clinical keratoconus from non keratoconic thin cornea eyes. However, the specificity levels of these parameters were relatively limited in the diagnosis of subclinical keratoconus. PMID- 29566543 TI - Beetroot-based gel supplementation improves handgrip strength and forearm muscle O2 saturation but not exercise tolerance and blood volume in jiu-jitsu athletes. AB - The ergogenic effect of beetroot on the exercise performance of trained cyclists, runners, kayakers, and swimmers has been demonstrated. However, whether or not beetroot supplementation presents a beneficial effect on the exercise performance of jiu-jitsu athletes remains inconclusive. Therefore, the present study assessed the effect of beetroot-based gel (BG) supplementation on maximal voluntary contraction (MVC), exercise time until fatigue (ETF), muscle O2 saturation (SmO2), blood volume (tHb), and plasma nitrate and lactate in response to handgrip isotonic exercise (HIE) in jiu-jitsu athletes. In a randomized, crossover, double-blind design, 12 jiu-jitsu athletes performed 3 sets of HIE at 40% of the MVC until fatigue after 8 days (the eighth dose was offered 120 min previous exercise) of BG supplementation or a nitrate-depleted gel (PLA), and forearm SmO2 and tHb were continuously monitored by using near-infrared spectroscopy. Blood samples were taken before, immediately after exercise, and 20 min after exercise recovery in the PLA and BG conditions. MVC was evaluated at baseline and 20 min after HIE. There was a significant reduction in DeltaMVC decline after HIE in the BG condition. Forearm SmO2 during exercise recovery was significantly greater only after BG supplementation. No significant difference in ETF and tHb were observed between both BG and PLA in response to HIE. Plasma nitrate increased only after BG, whereas the exercise-induced increase in plasma lactate was significantly lower in BG when compared with PLA. In conclusion, BG supplementation may be a good nutritional strategy to improve forearm SmO2 and prevent force decline in response to exercise in jiu-jitsu athletes. PMID- 29566544 TI - The effects of priming exercise on the VO2 slow component and the time-course of muscle fatigue during very-heavy-intensity exercise in humans. AB - We hypothesized that prior exercise would attenuate the muscle fatigue accompanied by oxygen uptake slow-component (VO2SC) behavior during a subsequent very-heavy (VH)-intensity cycling exercise. Thirteen healthy male subjects performed tests to determine the critical power (CP) and the fixed amount of work above CP ([Formula: see text]) and performed 6 square-wave bouts until 3 or 8 min, each at a work rate set to deplete 70% [Formula: see text] in 8 min, with a maximal isokinetic effort before and after the conditions without (VHCON) and with prior exercise (VHEXP), to measure the cycling peak torque decrement. The VO2SC magnitude at 3 min (VHCON = 0.280 +/- 0.234, VHEXP = 0.116 +/- 0.109 L.min 1; p = 0.04) and the VO2SC trajectory were significantly lower for VHEXP (VHCON = 0.108 +/- 0.042, VHEXP = 0.063 +/- 0.031 L.min-2; p < 0.01), leading to a VO2SC magnitude at the eighth minute that was significantly lower than VHCON (VHCON = 0.626 +/- 0.296 L.min-1, VHEXP = 0.337 +/- 0.179; p < 0.01). Conversely, peak torque progressively decreased from pre-exercise to 3 min (Deltatorque = 21.5 +/- 7.7 vs. 19.6 +/- 9.2 Nm) and to 8 min (Deltatorque = 29.4 +/- 15.8 vs. 27.5 +/- 12.0 Nm) at VHCON and VHEXP, respectively, without significant differences between conditions. Regardless of the condition, there was a significant relationship between Deltatorque and the VO2SC (R2: VHCON = 0.23, VHEXP = 0.25; p = 0.01). Considering that "priming" effects on the VO2SC were not accompanied by the muscle force behavior, these findings do not support the hypothesis of a "causal" relationship between the time-course of muscle fatigue and VO2SC. PMID- 29566545 TI - Effect of duration and severity of migraine on retinal nerve fiber layer, ganglion cell layer, and choroidal thickness. AB - PURPOSE:: To investigate the factors in migraine that have the highest significance on retinal and choroidal layers' thickness. METHODS:: Ninety patients with migraine and 40 age-matched healthy participants were enrolled in this observational, cross-sectional study. After full ophthalmological examination, spectral domain-optical coherence tomography was done for all patients measuring the thickness of ganglion cell layer and retinal nerve fiber layer. Enhanced depth imaging technique was used to measure the choroidal thickness. RESULTS:: There was significant thinning in the superior and inferior ganglion cell layers, all retinal nerve fiber layer quadrants, and all choroidal quadrants (except for the central subfield) in migraineurs compared to controls. The duration of migraine was significantly correlated with ganglion cell layer, retinal nerve fiber layer, and all choroidal quadrants, while the severity of migraine was significantly correlated with ganglion cell layer and retinal nerve fiber layer only. Multiregression analysis showed that the duration of migraine is the most important determinant factor of the superior retinal nerve fiber layer quadrant (beta = -0.375, p = 0.001) and in all the choroidal quadrants (beta = -0.531, -0.692, -0.503, -0.461, -0.564, respectively, p < 0.001), while severity is the most important determinant factor of inferior, nasal, and temporal retinal nerve fiber layer quadrants (beta = -0.256, -0.335, -0.308; p = 0.036, 0.005, 0.009, respectively) and the inferior ganglion cell layer hemisphere (beta = -0.377 and p = 0.001). CONCLUSION:: Ganglion cell layer, retinal nerve fiber layer, and choroidal thickness are significantly thinner in patients with migraine. The severity of migraine has more significant influence in the thinning of ganglion cell layer and retinal nerve fiber layer, while the duration of the disease affected the choroidal thickness more. PMID- 29566546 TI - Systematic review of the effect of economic compensation and incentives on uptake of voluntary medical male circumcision among men in sub-Saharan Africa. AB - Voluntary medical male circumcision (VMMC) prevalence in priority countries in sub-Saharan Africa, particularly among men aged >=20 years, has not yet reached the goal of 80% coverage recommended by the World Health Organization. Determining novel strategies to increase VMMC uptake among men >=20 years is critical to reach HIV epidemic control. We conducted a systematic review to analyze the effectiveness of economic compensation and incentives to increase VMMC uptake among older men in order to inform VMMC demand creation programs. The review included five qualitative, quantitative, and mixed methods studies published in peer reviewed journals. Data was extracted into a study summary table, and tables synthesizing study characteristics and results. Results indicate that cash reimbursements for transportation and food vouchers of small nominal amounts to partially compensate for wage loss were effective, while enrollment into lotteries offering prizes were not. Economic compensation provided a final push toward VMMC uptake for men who had already been considering undergoing circumcision. This was in settings with high circumcision prevalence brought by various VMMC demand creation strategies. Lottery prizes offered in the studies did not appear to help overcome barriers to access VMMC and qualitative evidence suggests this may partially explain why they were not effective. Economic compensation may help to increase VMMC uptake in priority countries with high circumcision prevalence when it addresses barriers to uptake. Ethical considerations, sustainability, and possible externalities should be carefully analyzed in countries considering economic compensation as an additional strategy to increase VMMC uptake. PMID- 29566548 TI - The role of ARFI elastography to evaluate microstructrual changes of patients with testicular microlithiasis. AB - BACKGROUND: Testicular microlithiasis (TML) is thought to cause microstructural changes in the parenchyma of the testis, but it is difficult to demonstrate this by ultrasonography. It may be possible to evaluate microstructural changes in the testis by Acoustic Radiation Force Impulse (ARFI) elastography, which measures tissue stiffness. PURPOSE: To assess the tissue stiffness of testicles of children with TML and to compare them with the healthy control group. MATERIAL AND METHODS: Between November 2015 and May 2016, 25 pediatric patients with TML and 24 healthy children were enrolled in the study (mean age for TML and control group 6.7 +/- 3.17 and 7.9 +/- 4.18 years, respectively). Testicular volumes and mean shear wave velocity (SWV) values were calculated and compared with each other in both groups. RESULTS: There was no significant difference in average testicular volumes between the TML group and the control group (1.14 cm3, 1.21 cm3, respectively; P = 0.986). Mean SWV of the testicles with TML and normal testicles with control group was 1.18 +/- 0.22 cm/s and 0.88 +/- 0.11 cm/s, respectively. The SWV of the testicles with TML was higher than the normal testicles and this was statistically significant ( P < 0.001). CONCLUSION: This study has shown that tissue stiffness in patients with TML is increased compared to the normal population. ARFI elastography helps the early detection of microstructural changes in TML and can be used for screening and follow-up.

AB - BACKGROUND: The artificial pancreas (AP) system, a technology that automatically administers exogenous insulin in people with type 1 diabetes mellitus (T1DM) to regulate their blood glucose concentrations, necessitates the estimation of the amount of active insulin already present in the body to avoid overdosing. METHOD: An adaptive and personalized plasma insulin concentration (PIC) estimator is designed in this work to accurately quantify the insulin present in the bloodstream. The proposed PIC estimation approach incorporates Hovorka's glucose insulin model with the unscented Kalman filtering algorithm. Methods for the personalized initialization of the time-varying model parameters to individual patients for improved estimator convergence are developed. Data from 20 three days-long closed-loop clinical experiments conducted involving subjects with T1DM are used to evaluate the proposed PIC estimation approach. RESULTS: The proposed methods are applied to the clinical data containing significant disturbances, such as unannounced meals and exercise, and the results demonstrate the accurate real-time estimation of the PIC with the root mean square error of 7.15 and 9.25 mU/L for the optimization-based fitted parameters and partial least squares regression-based testing parameters, respectively. CONCLUSIONS: The accurate real time estimation of PIC will benefit the AP systems by preventing overdelivery of insulin when significant insulin is present in the bloodstream.

AB - BACKGROUND: Long-term intensive training induces physiological, morphological, and functional adaption of the athlete's heart. PURPOSE: To evaluate the development of athlete's heart during a mid-term follow-up of competitive athletes using cardiac magnetic resonance (CMR). MATERIAL AND METHODS: Eighteen competitive long-distance runners and triathletes (age 43 +/- 13 years, 3 women) were prospectively examined in a longitudinal follow-up study 5.05 +/- 0.6 years after baseline. CMR at 1.5-T was performed for functional and late gadolinium enhancement (LGE) imaging. Left ventricular (LV) and right ventricular (RV) end diastolic volume (LVEDV, RVEDV) as well as ejection fraction (LVEF, RVEF), LV myocardial mass (LVMM), and atrial sizes were determined and compared to baseline in matched pairs statistics for paired difference. RESULTS: LVEDV (197 +/- 38 mL vs. 196 +/- 38 mL, paired difference -0.9 mL, P = 0.7) and LVEF (62 +/- 7% vs. 62 +/- 5%, paired difference 0.1%, P = 0.9) did not change during the follow-up period, whereas LVMM increased significantly (149 +/- 31 g vs.164 +/- 32 g, paired difference 14 g, P < 0.0001). RVEDV significantly increased from 221 +/- 47 mL at baseline to 230 +/- 52 mL (paired difference 10 mL, P = 0.0033). RVEF decreased from baseline 57 +/- 8% to 53 +/- 7% (paired difference -3%, P = 0.0234). Left atrial size showed no significant changes (24 +/- 5 cm2 vs. 25 +/- 6 cm2, paired difference 0.5 cm2, P = 0.17) and right atrial size increased significantly (30 +/- 5 cm2 vs. 32 +/- 4 cm2, paired difference 2 cm2, P = 0.0054). CONCLUSION: This study supports the theory of ongoing remodeling in an athlete's heart. Predominantly the right heart can further enlarge in a mid-term period. This response seems not linearly dependent on a steady, decreased, or increased training volume. PMID- 29566550 TI - 68Ga-somatostatin receptor analogs and 18F-FDG PET/CT in the localization of metastatic pheochromocytomas and paragangliomas with germline mutations: a meta analysis. AB - BACKGROUND: Metastatic pheochromocytoma and paraganglioma (PCs/PGLs) show high germline mutation, and 18F-FDG and 68Ga-DOTA peptide positron emission tomography/computed tomography (PET/CT) imaging are recommended for the diagnosis of metastatic of PCs. However, there has been lack of direct comparison of the two modalities in the diagnosis of metastatic of PCs up to now. PURPOSE: To evaluate and compare the value of localization of 68Ga-somatostatin receptor analogs and 18F-FDG in the diagnosis of metastatic PCs/PGLs. MATERIAL AND METHODS: A comprehensive literature search of PubMed/MEDLINE, ScienceDirect, and Web of Science was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines published in August 2016. We critically reviewed all studies based on the PICOS criteria. QUADAS-2 was used to evaluate the quality of the methodology of the included studies. RESULTS: This meta-analysis included 17 studies (629 patients, average age [mean +/- SD] = 42.7 +/- 6.3 years). The pooled sensitivity and specificity of 18F-FDG and 68Ga peptides were 0.85 (95% confidence interval [CI] = 0.78-0.91) and 0.55 (95% CI = 0.37-0.73), and 0.95 (95% CI = 0.92-0.97) and 0.87 (95% CI = 0.63-0.96), respectively. The area under the sROC curves of the 18F-FDG and 68Ga peptides were 0.88 (95% CI = 0.85-0.91) and 0.78 (95% CI = 0.74-0.81), respectively. A subgroup analysis demonstrated that the difference at the per-lesion level and gene mutation level was significant. CONCLUSION: Compared to 18F-FDG PET/CT, the 68Ga-somatostatin receptor demonstrated good performance in the localization of metastatic PCs/PGLs, especially those with germline mutations. The use of the 68Ga-somatostatin receptor can be a new tool in the diagnosis of metastatic PCs/PGLs. PMID- 29566551 TI - In vivo MRI detection of atherosclerosis in ApoE-deficient mice by using tenascin C-targeted USPIO. AB - BACKGROUND: Atherosclerosis is the main cause of cardiovascular and cerebrovascular diseases. Non-invasive molecular imaging to detect and characterize the plaques is essential for reducing life-threatening cardiovascular events. PURPOSE: To investigate the possibility of the anti tenascin-C-USPIO specific probe as a molecular marker of atherosclerotic plaques detected by 7.0-T magnetic resonance imaging (MRI). MATERIAL AND METHODS: Twenty ApoE-/- mice fed with a high fat diet were used for detecting the aorta arch atherosclerotic plaques by 7.0-T MRI at 16 and 24 weeks. Ten mice in the targeted group were injected with anti-tenascin-C-USPIO and another ten in the control group were injected with pure USPIO (n = 5 each time point in each group). Histopathologic examination was used to evaluate the plaques and immunohistochemistry analysis was used to compare tenascin-C expression. RESULTS: The relative signal intensity (rSI) changes of the targeted group decreased more than those of the control group (16 weeks: -15.65 +/- 0.78% vs. -3.43 +/- 2.57%; 24 weeks: -26.38 +/- 1.54% vs. -11.12 +/- 1.60%, respectively; P < 0.05). Histopathological analyses demonstrated visible atherosclerotic plaques formation and development over time from 16 weeks to 24 weeks. Tenascin-C expression of the plaques at 24 weeks was higher than that at 16 weeks (0.22 +/- 0.04 vs. 0.13 +/- 0.02, P < 0.05). The MR images correlated well with the progression of atherosclerotic plaques. CONCLUSION: Tenascin-C expression increased with the progression of atherosclerosis. Anti-tenascin-C-USPIO could provide a useful molecular imaging tool for detecting and monitoring atherosclerotic plaques by MRI. PMID- 29566552 TI - Intraocular lens bicylindric power calculation method: Using both flat and steep K readings to improve intraocular lens power prediction. AB - PURPOSE: To compare and analyze the accuracy of the refractive outcomes obtained in intraocular lens power calculation using the classical calculation method with mean keratometry (K) and the calculation method with both K meridians presented in this article. METHODS: A total of 62 eyes of 62 subjects who were undergoing cataract surgery were included in this study. Optical biometry was performed using mean K and Haigis formula for classical intraocular lens calculation methods to achieve intraocular lens power; 4 weeks after surgery, prior to medical discharge, subjective refraction was made. Alternatively, intraocular lens power was calculated with bicylindric method using both keratometry readings, obtaining spherocylindrical refractive expected outcomes. Finally, results obtained with intraocular lens calculation methods, bicylindric method, and Haigis formula were compared. RESULTS: Spherical equivalent calculated by classical intraocular lens calculation methods using Haigis formula (H-SE) was 0.027 +/- 0.115 D and using bicylindric method (B-SE) was -0.080 +/- 0.222 D. Achieved spherical equivalent obtained 4 weeks after surgery (A-SE) was -0.144 +/ 0.268 D. Difference between H-SE and A-SE was -0.117 D (p = 0.002). Difference between B-SE and A-SE was not significant (-0.054 D, p = 0.109). Analysis in refraction groups showed a positive correlation between A-SE confronted to B-SE and H-SE (r = 0.313; p = 0.013 and r = 0.562; p < 0.001, respectively). This indicated a reliability in ametropic group prediction of 0.767 in H-SE and 0.843 in B-SE. CONCLUSION: Intraocular lens calculation with bicylindric method could be more accurate and had more reliability than classical intraocular lens calculation method. Bicylindric method adds astigmatism control and provides a reliable expected spherocylindrical refraction. PMID- 29566553 TI - Editorial by Paul Tibbles in dialogue with Ncazelo Ncube. PMID- 29566554 TI - Challenges and impossibilities of 'standing alongside' in an intolerable context: Learning from refugees and volunteers in the Calais camp. AB - This article describes the experience of setting up a psychosocial and therapeutic support project in the French Calais refugee camp, by a group of family therapists and clinical psychologists from the United Kingdom. This came about in response to reports of a humanitarian crisis unfolding on our doorstep, with the British government's lack of support for the growing numbers of refugees gathering along the UK border with France. The project involved working alongside other agencies in the camp to provide psychosocial and resilience-based therapeutic support to unaccompanied young people, women, children and their families and also to many volunteers in the camp. The process of setting up the work is described, as well as the challenges and dilemmas of offering an intervention in extremely unsafe and insanitary conditions, where for most the experience of trauma was ongoing. The project was informed by systemic-narrative practice and community/liberation psychology, which incorporate the political and social context. A narrative framework offered a way of drawing on people's strengths and resources, rooted in their cultural and social histories and helping them connect with preferred identities, which we found to be essential in the context of ongoing crisis. PMID- 29566555 TI - Positive thinking elevates tolerance: Experimental effects of happiness on adolescents' attitudes toward asylum seekers. AB - Inducing emotional reactions toward social groups can influence individuals' political tolerance. This study examines the influence of incidental fear and happiness on adolescents' tolerant attitudes and feelings toward young Muslim asylum seekers. In our experiment, 219 16- to 21-year-olds completed measures of prejudicial attitudes. After being induced to feel happiness, fear, or no emotion (control), participants reported their tolerant attitudes and feelings toward asylum-seeking young people. Participants assigned to the happiness condition demonstrated more tolerant attitudes toward asylum-seeking young people than did those assigned to the fear or control conditions. Participants in the control condition did not differ from participants in the fear condition. The participants in the happiness condition also had more positive feelings toward asylum-seeking young people than did participants in the control condition. The findings suggest that one way to increase positive attitudes toward asylum seeking young people is to improve general emotional state. PMID- 29566556 TI - Stories of trauma in family therapy with refugees: Supporting safe relational spaces of narration and silence. AB - With the sharp increase of refugees' arrival and resettlement in western communities, adequate mental health care forms a pivotal dimension in host societies' responses to those individuals and communities seeking protection within their borders. Here, clinical literature shows a growing interest in the development of family therapy approaches with refugees, in which therapeutic practice engages with the pivotal role of refugee family dynamics in posttrauma reconstruction and adaptation in resettlement and aims at supporting posttrauma reconstruction through strengthening capacities to restore safety, meaning and connectedness within family relationships. In this article, we focus on the narrative restoration of meaning as central mode of posttrauma reparation and explore its specific dynamics and relational complexities in the context of therapeutic practice with refugee families. Hereto, we integrate theoretical and clinical scholarly work on trauma narration and its intersection with empirical findings on trauma communication in refugee families. Furthermore, we develop case reflections to illustrate different processes of engaging with trauma narration in refugee family therapy. This analysis develops an understanding of the multivoiced ways in which refugee families engage with traumatic suffering through different modes of expression that may entail both narration and silence and explores how family therapeutic practices can engage and mobilize voices of narration and silence as relational stories of restoration. PMID- 29566557 TI - Mental health of unaccompanied asylum-seeking adolescents previously held in British detention centres. AB - AIM: To investigate whether the mental health of unaccompanied asylum-seeking children (UASC) was negatively affected by having their ages disputed and being detained. METHOD: Participants within this cross-sectional study were 35 UASC, aged between 13 and 17 when they were detained. Some years later, a team of child mental health professionals interviewed them to assess their current mental health and to determine, as far as possible, the impact that having their age disputed and being detained may have had on their mental health. The Structured Clinical Interview for DSM-IV (SCID-IV), Reactions of Adolescents to Traumatic Stress (RATS), Stressful Life Events (SLE) and Detention Experiences Checklist-UK version (DEC-UK) were administered. RESULTS: The vast majority of UASC reported being negatively affected. Based on diagnostic interviews using the SCID-IV, self report measures and contemporaneous records, the professionals reported a diagnosis of post-traumatic stress disorder (PTSD) developing in 29% ( n = 10), PTSD exacerbated in 51% ( n = 18), major depressive disorder (MDD) developing in 23% ( n = 8) and MDD exacerbated in 40% ( n = 14). A total of 3 years post detention, 89% ( n = 31) met diagnostic criteria for psychiatric disorders and reported high PTSD symptoms. CONCLUSION: There was a high prevalence of psychiatric disorder. The additional stress of age dispute procedures and detention was judged to have been harmful. PMID- 29566558 TI - In Vivo Imaging of Hydrogen Peroxide with HyPer Probes. AB - SIGNIFICANCE: Hydrogen peroxide (H2O2) is a key signaling molecule involved in the regulation of both physiological and pathological cellular processes. Genetically encoded HyPer probes are currently among the most effective approaches for monitoring H2O2 dynamics in various biological systems because they can be easily targeted to specific cells and organelles. Since its development in 2006, HyPer has proved to be a robust and powerful tool in redox biology research. Recent Advances: HyPer probes were used in a variety of models to study the role of H2O2 in various redox processes. HyPer has been increasingly used in the past few years for in vivo studies, which has already led to many important discoveries, for example, that H2O2 plays a key role in the regulation of signaling cascades involved in development and aging, inflammation, regeneration, photosynthetic signaling, and other biological processes. CRITICAL ISSUES: In this review, we focus on the main achievements in the field of redox biology that have been obtained from in vivo experiments using HyPer probes. FUTURE DIRECTIONS: Further in vivo studies of the role of H2O2 largely depend on the development of more suitable versions of HyPer for in vivo models: those having brighter fluorescence and a more stable signal in response to physiological changes in pH.

AB - PURPOSE: A screening instrument (0-100 points) to predict return-to-work (RTW) problems was developed. We tested the predictive validity in patients with mental diseases (MD) and musculoskeletal diseases (MSD). MATERIALS AND METHODS: A prospective multicenter study with questionnaires at admission and 3 months after rehabilitation was conducted. Patients with MD and MSD were included. The outcome was occurrence of RTW problems during the follow-up. Receiver operating characteristic analyses were performed. Sensitivity, specificity, and predictive values were calculated for each disease group using the threshold of 27 points. RESULTS: There were 401 patients with MD (n = 250) and MSD (n = 151) included in the study, and 31.8% and 46.4% reported RTW problems during the follow-up, respectively. The area under curve was 0.885 (0.838-0.920) and 0.899 (0.841 0.943). The sensitivity rates were 87.1% and 87.5% and the specificity rates were 79.9% and 88.4% for MD and MSD, respectively. The post-test probability of experiencing RTW problems was 78.9% for MD and 77.8% for MSD. Analyses including only employed patients showed similar results. CONCLUSIONS: The screening predicts short-term RTW problems after rehabilitation in patients with mental or MSD regardless of employment. The threshold of 27 points was confirmed as reasonable, but alternatives in the range of 20-30 points can also be recommended. Implications for Rehabilitation The SIMBO is a short and economic screening predicting future problems during the return to work (RTW) in patients with mental or musculoskeletal diseases. The SIMBO can be recommended to detect the initial RTW chance at the beginning of the rehabilitation process. This paper implied that there are mainly generic factors predicting the success of an RTW. Based on this it is possible to use one screening for different disease groups. PMID- 29566560 TI - Overcoming problems of poor drug penetration into bacteria: challenges and strategies for medicinal chemists. AB - INTRODUCTION: Bacterial cell walls and membranes provide essential protection for bacteria against environmental influences. Different bacteria possess different cell envelopes and understanding each of these structures is crucial for the design of effective antibacterial drugs whose targets are intracellular. Optimal properties of drugs that are required for their entry into bacteria are still hard to predict. The guidelines that are suitable and well established for the penetration of a drug into eukaryotic cells are poorly adaptable to the complex world of pathogens. Areas covered: The factors that govern the penetration of anti-infection drugs into bacteria are examined and the available strategies to overcome this therapeutically very important barrier are reviewed. The areas covered include optimization of the physicochemical properties of compounds, utilization of iron-chelating compounds, i.e. siderophores, the use of efflux pump inhibitors, and of carriers such as liposomes. Expert opinion: Although several rules governing permeation have recently been proposed for effective antibacterial drugs, none of them has been so far established as the 'golden' rule. Thus, new research is needed to find a more general approach on how to increase the concentration of antibacterial compounds in bacterial cells. PMID- 29566561 TI - A multimodality imaging-compatible insertion robot with a respiratory motion calibration module designed for ablation of liver tumors: a preclinical study. AB - PURPOSE: To test the accuracy and efficacy of the multimodality imaging compatible insertion robot with a respiratory motion calibration module designed for ablation of liver tumors in phantom and animal models. To evaluate and compare the influences of intervention experience on robot-assisted and ultrasound-controlled ablation procedures. METHODS: Accuracy tests on rigid body/phantom model with a respiratory movement simulation device and microwave ablation tests on porcine liver tumor/rabbit liver cancer were performed with the robot we designed or with the traditional ultrasound-guidance by physicians with or without intervention experience. RESULTS: In the accuracy tests performed by the physicians without intervention experience, the insertion accuracy and efficiency of robot-assisted group was higher than those of ultrasound-guided group with statistically significant differences. In the microwave ablation tests performed by the physicians without intervention experience, better complete ablation rate was achieved when applying the robot. In the microwave ablation tests performed by the physicians with intervention experience, there was no statistically significant difference of the insertion number and total ablation time between the robot-assisted group and the ultrasound-controlled group. The evaluation by the NASA-TLX suggested that the robot-assisted insertion and microwave ablation process performed by physicians with or without experience were more comfortable. CONCLUSION: The multimodality imaging-compatible insertion robot with a respiratory motion calibration module designed for ablation of liver tumors could increase the insertion accuracy and ablation efficacy, and minimize the influence of the physicians' experience. The ablation procedure could be more comfortable with less stress with the application of the robot.

PMID- 29566562 TI - Transurethral high-intensity ultrasound for treatment of stress urinary incontinence (SUI): simulation studies with patient-specific models. AB - BACKGROUND: Stress urinary incontinence (SUI) is prevalent in adult women, attributed to weakened endopelvic supporting tissues, and typically treated using drugs and invasive surgical procedures. The objective of this in silico study is to explore transurethral high-intensity ultrasound for delivery of precise thermal therapy to the endopelvic tissues adjacent to the mid-urethra, to induce thermal remodeling as a potential minimally invasive treatment alternative. METHODS: 3D acoustic (Rayleigh-Sommerfeld) and biothermal (Pennes bioheat) models of the ultrasound applicator and surrounding tissues were devised. Parametric studies over transducer configuration [frequency, radius-of-curvature (ROC)] and treatment settings (power, duration) were performed, and select cases on patient specific models were used for further evaluation. Transient temperature and thermal dose distributions were calculated, and temperature and dose metrics reported. RESULTS: Configurations using a 5-MHz curvilinear transducer (3.5 * 10 mm, 28 mm ROC) with single 90 s sonication can create heated zones with 11 mm penetration (>50 degrees C) while sparing the inner 1.8 mm (<45 degrees C) radial depth of the urethral mucosa. Sequential and discrete applicator rotations can sweep out bilateral coagulation volumes (1.4 W power, 15 degrees rotations, 600 s total time), produce large volumetric (1124 mm3 above 60 EM43 degrees C) and wide angular (~50.5 degrees per lateral sweep) coverage, with up to 15.6 mm thermal penetration and at least 1.6 mm radial urethral protection (<5 EM43 degrees C). CONCLUSION: Transurethral applicators with curvilinear ultrasound transducers can deliver spatially selective temperature elevations to lateral mid urethral targets as a possible means to tighten the endopelvic fascia and adjacent tissues. PMID- 29566564 TI - Association between preterm labour and pelvic floor muscle function. AB - We hypothesised that the pressure on the cervix increases with advancing gestation and it may lead to a cervical shortening and cause preterm labour in women with weak pelvic floor muscles. The aim of this prospective study was to measure vaginal resting pressure and pelvic floor muscle strength in the first trimester of pregnancy and to investigate their effects on labour. A study was conducted on the pregnant women with a low risk for preterm birth. The pelvic floor muscle strength and vaginal resting pressure were assessed in 320 pregnant women at their first trimester with a vaginal pressure measurement device. Fifty two pregnant women were hospitalised for tocolytic therapy because of spontaneous preterm labour. Thirty-two of them (10.2%) had a preterm delivery despite the tocolytic therapy. Both the vaginal resting pressure (p = .009, 95%CI: 0.8; 5.9) and the pelvic floor muscle strength (p = .01, 95%CI: 3.5; 13.1) were significantly lower in the women with a preterm labour. Impact statement What is already known on this subject? The pelvic floor muscles have an essential role in continence and provide support to the pelvic organs. They also have an impact on labour. The pelvic floor muscles should distend to allow the passage of the foetus during labour. The rotation and flexion of the foetal head is due to the pelvic floor resistance. The effect of a vaginal birth on the pelvic floor's function is readily understood. On the other hand, the effect of the pelvic floor muscle function on labour is still controversial. What do the results of this study add? This prospective study showed that there is a negative association between the pelvic floor muscle strength and preterm labour. This is the first clinical study indicating that weak pelvic floor muscles may cause a preterm labour. What are the implications of these findings for clinical practice and/or further research? Pelvic floor physical therapy may be an alternative preventive strategy to reduce the risk of a spontaneous preterm birth. PMID- 29566565 TI - In the aftermath of SPRINT: further comparison of unattended automated office blood pressure measurement and 24-hour blood pressure monitoring. AB - AIMS: Several papers reported that unattended automated office blood pressure (uAutoOBP) is closely related to daytime ambulatory blood pressure monitoring (ABPM). In the present study, we aim to study uAutoOBP and its relation to 24 hour ABPM and ABPM variability. MATERIAL AND METHODS: Stable treated hypertensive subjects were examined in two Czech academic hypertension centres. uAutoOBP was measured with the BP Tru device; attended BP three times with auscultatory method (AuscOBP) by the physician. ABPM was performed within one week from the clinical visit. RESULTS: Data on 98 subjects aged 67.7 +/- 9.3 years with 24-hour ABPM 120.3 +/- 10.6/72.7 +/- 7.9 mm Hg are reported. uAutoOBP was lower than 24-hour (by -5.2 +/- 11.3/-0.5 +/- 6.9 mm Hg) and daytime (by -6.7 +/- 12.82.4 +/- 8.0 mm Hg) ABPM and the individual variability of the difference was very large (up to 30 mm Hg). The correlation coefficients between ABPM and uAutoOBP were similar compared to AuscOBP (p >= .17). Variability of uAutoOBP, but not AuscOBP, readings during one clinical visit was related to short-term blood pressure variability of ABPM. The difference between AuscOBP and uAutoOBP was larger in patients with white-coat effect compared to other blood pressure control groups (25.1 +/- 7.0 vs. 2.2 +/- 10.3 mm Hg; p = .0036). CONCLUSIONS: Our study shows that uAutoOBP is not good predictor of ambulatory blood pressure monitoring, not even of the daytime values. It might, however, indicate short-term blood pressure variability and, when compared with AuscOBP, also detect patients with white-coat effect. PMID- 29566566 TI - Combination of three-dimensional ultrasound measurement of foetal adrenal gland enlargement and placental alpha microglobulin-1 for the prediction of the timing of delivery within seven days in women with threatened preterm labour and preterm labour. AB - The aim of this study was to predict the timing of delivery within seven days in singleton pregnant women with threatened preterm labour and preterm labour by using a three-dimensional (3D) ultrasound measurement of foetal adrenal gland volume enlargement, a foetal zone enlargement and cervicovaginal placental alpha microglobulin-1 (PAMG-1) test. This prospective cohort study included singleton pregnant women at 22-36+6 weeks of gestation who presented with threatened preterm labour and with preterm labour. Transabdominal 3D ultrasound measurement of the whole foetal adrenal gland and of the foetal adrenal zone were performed. Qualitative cervicovaginal PAMG-1 detection was performed at the same time. One hundred and fifty-four pregnant women were included into the study. Eighty-four pregnant women had threatened preterm labour and seventy pregnant women had preterm labour. Twenty-nine pregnant women (18%) delivered within seven days. Use of foetal adrenal gland volume enlargement, foetal zone enlargement and the PAMG 1 test in combination increased sensitivity; if one parameter was positive, the sensitivity, specificity, positive predictive value and negative predictive value were 82.8%, 27.2%, 20.9% and 87.2%, respectively, in the prediction of the timing of delivery within seven days. The combination of foetal adrenal gland enlargement and PAMG-1 increased sensitivity for the prediction of the timing of delivery within seven days in pregnant women presenting with threatened preterm labour and preterm labour. Impact Statement What is already known on this subject? An increased foetal adrenal gland volume is significantly correlated with the risk of preterm birth. What do the results of this study add? The combination of a foetal adrenal gland enlargement and a placental alpha microglobulin-1 increased sensitivity for the prediction of the timing of delivery within seven days in pregnant women presenting with threatened preterm labour and preterm labour. What are the implications of these findings for clinical practice and/or further research? The combination of a foetal adrenal gland enlargement and placental alpha microglobulin-1 may be used for the prediction of the timing of delivery within seven days in pregnant women presenting with threatened preterm labour and with preterm labour. PMID- 29566567 TI - Exploring Dutch surgeons' views on volume-based policies: a qualitative interview study. AB - Objective In many countries, the evidence for volume-outcome associations in surgery has been transferred into policy. Despite the large body of research that exists on the topic, qualitative studies aimed at surgeons' views on, and experiences with, these volume-based policies are lacking. We interviewed Dutch surgeons to gain more insight into the implications of volume-outcome policies for daily clinical practice, as input for effective surgical quality improvement. Methods Semi-structured interviews were conducted with 20 purposively selected surgeons from a stratified sample for hospital type and speciality. The interviews were recorded, transcribed verbatim and underwent inductive content analysis. Results Two overarching themes were inductively derived from the data: (1) minimum volume standards and (2) implications of volume-based policies. Although surgeons acknowledged the premise 'more is better', they were critical about the validity and underlying evidence for minimum volume standards. Patients often inquire about caseload, which is met with both understanding and discomfort. Surgeons offered many examples of controversies surrounding the process of determining thresholds as well as the ways in which health insurers use volume as a purchasing criterion. Furthermore, being held accountable for caseload may trigger undesired strategic behaviour, such as unwarranted operations. Volume-based policies also have implications for the survival of low volume providers and affect patient travel times, although the latter is not necessarily problematic in the Dutch context. Conclusions Surgeons in this study acknowledged that more volume leads to better quality. However, validity issues, undesired strategic behaviour and the ways in which minimum volume standards are established and applied have made surgeons critical of current policy practice. These findings suggest that volume remains a controversial quality measure and causes polarization that is not conducive to a collective effort for quality improvement. We recommend enforcing thresholds that are based on the best achievable level of consensus and assessing additional criteria when passing judgement on quality of care.

AB - PURPOSE: Speech language therapists increasingly are using telehealth to enhance the accessibility of their services. It is unclear, however, how play-based therapy for children can be delivered via telehealth. In particular, modalities such as videoconferencing do not enable physical engagement between therapists and clients. The aim of our reported study was to understand how physical objects such as toys are used in similar and different ways across videoconferenced and "face-to-face" (hereafter, "in-person") therapy. METHODS: We used conversation analytic methods to compare video-recorded therapy sessions for children delivered across in-person and telehealth settings. Utilising a broader corpus of materials, our analysis focused on four client-therapist dyads: two using videoconferencing, and two who met in-person. RESULTS: Both videoconferencing and in-person sessions enabled routine affordances and challenges for delivering therapy. Within in-person therapy, therapists made access to objects contingent upon the client producing some target expression. This contingency usually was achieved by restricting physical access to these objects. Restricting access to a toy was not necessary in videoconferenced therapy; therapists instead used techniques to promote engagement. CONCLUSIONS: When delivering play-based therapy via telehealth, our study demonstrates how practitioners adapt the intervention to suit the particular medium of its delivery. Implications for Rehabilitation Telehealth enhances equitable access for those who cannot physically access rehabilitation services. Telehealth modalities can create practical challenges, however, when delivering interventions such as play-based therapy. Practitioners should intentionally adapt telehealth interventions to suit the particular telehealth modality they are using. PMID- 29566568 TI - Sexual Responses Are Facilitated by High-Order Contextual Cues in Females but Not in Males. AB - Sexual responses are thought to be controlled by a brain module called the sexual module. Sexual strategies of males and females vary to a great extent, and sexual responses of males and females may be affected by their sexual strategies. However, the current view of the sexual module is that of a unisex module. This might be questionable since brain modules are defined as evolved cognitive mechanisms to solve adaptive problems which are different for males and females. We hypothesize that the sexual module responds differently in the presence of complex (high-order) contextual cues that are related to gender-dimorphic sexual strategies in males and females. We conducted a priming experiment in which stimuli related to sexual strategies were disentangled from their sexual meaning. Nonsexual priming pictures related to either economic resources or social interactions preceded a sexual-target picture in order to test whether the primes were able to modulate the subjective sexual response to the sexual target. In a control condition, priming pictures without relation to mating preferences but with similar emotional impact were presented. In males, sexual responses were similar in the experimental and control conditions. In females, however, primes related to economic resources or social interactions modulated sexual arousal significantly more than the control primes. Our findings suggest that brain modules dedicated to process the experimental primes were functionally connected with the sexual module in females more than in males, making females' sexual responses more prone to the impact of high-order cultural cues than males' sexual responses. A gender-dimorphic connectivity of the sexual module may be the way in which gender-dimorphic sexual strategies are implemented in the human mind. PMID- 29566570 TI - Three-dimensional assessment of the asymptomatic and post-stroke shoulder: intra rater test-retest reliability and within-subject repeatability of the palpation and digitization approach. AB - PURPOSE: Altered three-dimensional (3D) joint kinematics can contribute to shoulder pathology, including post-stroke shoulder pain. Reliable assessment methods enable comparative studies between asymptomatic shoulders of healthy subjects and painful shoulders of post-stroke subjects, and could inform treatment planning for post-stroke shoulder pain. The study purpose was to establish intra-rater test-retest reliability and within-subject repeatability of a palpation/digitization protocol, which assesses 3D clavicular/scapular/humeral rotations, in asymptomatic and painful post-stroke shoulders. METHODS: Repeated measurements of 3D clavicular/scapular/humeral joint/segment rotations were obtained using palpation/digitization in 32 asymptomatic and six painful post stroke shoulders during four reaching postures (rest/flexion/abduction/external rotation). Intra-class correlation coefficients (ICCs), standard error of the measurement and 95% confidence intervals were calculated. RESULTS: All ICC values indicated high to very high test-retest reliability (>=0.70), with lower reliability for scapular anterior/posterior tilt during external rotation in asymptomatic subjects, and scapular medial/lateral rotation, humeral horizontal abduction/adduction and axial rotation during abduction in post-stroke subjects. All standard error of measurement values demonstrated within-subject repeatability error <=5 degrees for all clavicular/scapular/humeral joint/segment rotations (asymptomatic <=3.75 degrees ; post-stroke <=5.0 degrees ), except for humeral axial rotation (asymptomatic <=5 degrees ; post-stroke <=15 degrees ). CONCLUSIONS: This noninvasive, clinically feasible palpation/digitization protocol was reliable and repeatable in asymptomatic shoulders, and in a smaller sample of painful post-stroke shoulders. Implications for Rehabilitation In the clinical setting, a reliable and repeatable noninvasive method for assessment of three-dimensional (3D) clavicular/scapular/humeral joint orientation and range of motion (ROM) is currently required. The established reliability and repeatability of this proposed palpation/digitization protocol will enable comparative 3D ROM studies between asymptomatic and post-stroke shoulders, which will further inform treatment planning. Intra-rater test-retest repeatability, which is measured by the standard error of the measure, indicates the range of error associated with a single test measure. Therefore, clinicians can use the standard error of the measure to determine the "true" differences between pre-treatment and post-treatment test scores. PMID- 29566571 TI - Respiratory measures in amyotrophic lateral sclerosis. AB - OBJECTIVE: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disease that causes skeletal muscle weakness, including muscles involved with respiration. Death often results from respiratory failure within 3-5 years. Monitoring respiratory status is therefore critical to ALS management, as respiratory/pulmonary function tests (PFTs) are used to make decisions including when to initiate noninvasive ventilation. Understanding the different respiratory and PFTs as they relate to disease progression and survival may help determine which tests are most suitable. METHODS: This review describes the tests used to assess respiratory muscle and pulmonary function in patients with ALS and the correlations between different respiratory measures and clinical outcomes measures. RESULTS: The most commonly used measurement, forced vital capacity (VC), has been shown to correlate with clinical milestones including survival, but also requires good motor coordination and facial strength to form a tight seal around a mouthpiece. Other tests such as slow VC, sniff inspiratory pressure, or transdiaphragmatic pressure with magnetic stimulation are also associated with distinct advantages and disadvantages. CONCLUSIONS: Therefore, how and when to use different tests remains unclear. Understanding how each test relates to disease progression and survival may help determine which is best suited for specific clinical decisions.

PMID- 29566572 TI - Effects Of Endothelin-1 On Intracellular Tetrahydrobiopterin Levels In Vascular Tissue. AB - OBJECTIVE: Tetrahydrobiopterin (BH4) is the essential cofactor of endothelial nitric oxide synthase (eNOS) and intracellular levels of BH4 is regulated by oxidative stress. The aim of this paper was to describe the influence of exogenous endothelin-1 on intracellular BH4 and its oxidation products dihydrobiopterin (BH2) and biopterin (B) in a wide range of vascular tissue. DESIGN: Segments of internal mammary artery (IMA) and human saphenous vein (SV) from 41 patients undergoing elective surgery were incubated in ET-1 (0.1 MUM). Aorta and lung from transgenic mice overexpressing ET-1 in the endothelium (ET TG) were analysed with regards to intracellular biopterin levels. Human umbilical vein endothelial cells (HUVEC) were incubated in ET-1 (0.1 MUM) and intracellular biopterin levels were analysed. From 6 healthy women undergoing caesarean section, subcutaneous fat was harvested and the resistance arteries in these biopsies were tested for ET-mediated endothelial dysfunction. RESULTS: In HUVEC, exogenous ET-1 (0.1 MUM) did not significantly change intracellular BH4, 1.54 +/- 1.7 vs 1.68 +/- 1.8 pmol/mg protein; p = .8. In IMA and SV, exogenous ET-1(0.1 MUM) did not change intracellular BH4 n = 10, p = .4. In aorta from wild type vs ET-TG mice there was no significant difference in intracellular BH4 between the groups: 1.3 +/- 0.49 vs 1.23 +/- 0.3 pmol/mg protein; p = .6. In resistance arteries (n = 6) BH4 together with DTE (an antioxidant) was not able to prevent ET-mediated endothelial dysfunction. CONCLUSION: ET-1 did not significantly alter intracellular tetrahydrobiopterin levels in IMA, SV, HUVEC or aorta from ET-TG mice. These findings are important for future research in ET-1 mediated superoxide production and endothelial dysfunction. PMID- 29566574 TI - Bcl-2/E1B-19KD-Interacting Protein 3/Light Chain 3 Interaction Induces Mitophagy in Spinal Cord Injury in Rats Both In Vivo and In Vitro. AB - Autophagy and mitophagy have been shown to occur in spinal cord injury (SCI). Bcl 2/E1B-19KD-interacting protein 3 (BNIP3) and its homologue, NIX, have been implicated in the regulation of mitophagy. The aim of this work was to characterize the mechanisms and role of BNIP3 in SCI-associated mitophagy. Our data showed that BNIP3, targeted to mitochondria, interacted with microtubule associated protein 1A/1B-light chain 3 (LC3), which is targeted to autophagosomes, thus forming a mitochondria-BNIP3-LC3-autophagosome complex and resulting in mitophagy. Downregulation of BNIP3 by RNA interference strengthened the mitochondrial function and decreased cell death in spinal cord neurons under hypoxia. Particularly, BNIP3 knockdown significantly improved neurological recovery and the number of neuronal nuclei-positive cells post-SCI in rats. The present study demonstrated that BNIP3 interacts with LC3 to induce mitophagy, whereas its inhibition provided protective neuronal effects in SCI rat models both in vivo and in vitro. PMID- 29566575 TI - Evaluating Comprehensive State Tobacco Prevention and Control Programs Using an Outcome Indicator Framework. AB - The outcome indicator framework helps tobacco prevention and control programs (TCPs) plan and implement theory-driven evaluations of their efforts to reduce and prevent tobacco use. Tobacco use is the single-most preventable cause of morbidity and mortality in the United States. The implementation of public health best practices by comprehensive state TCPs has been shown to prevent the initiation of tobacco use, reduce tobacco use prevalence, and decrease tobacco related health care expenditures. Achieving and sustaining program goals require TCPs to evaluate the effectiveness and impact of their programs. To guide evaluation efforts by TCPs, the Centers for Disease Control and Prevention's Office on Smoking and Health developed an outcome indicator framework that includes a high-level logic model and evidence-based outcome indicators for each tobacco prevention and control goal area. In this article, we describe how TCPs and other community organizations can use the outcome indicator framework in their evaluation efforts. We also discuss how the framework is used at the national level to unify tobacco prevention and control efforts across varying state contexts, identify promising practices, and expand the public health evidence base. PMID- 29566576 TI - Health Marketing for the Massachusetts Childhood Obesity Research Demonstration Study: A Case Study. AB - INTRODUCTION: This case study describes the Massachusetts Childhood Obesity Research Demonstration Study (MA-CORD) health marketing campaign, examines the strategies used in such campaigns, and offers lessons learned to improve health marketing for future interventions. MA-CORD Health Marketing Components and Implementation. The three main components were an outdoor printed advertisement and texting campaign, social media with a focus on Facebook, and the Summer Passport Program, an event-based initiative in parks for children. The advertisements consisted of billboards, bus advertisements, and handouts. The text messaging component, which required families to actively text a keyword to join, had a low opt-in rate. Facebook page "likes" increased from 1,024 to 1,453 in New Bedford and from 175 to 1,091 in Fitchburg. Fitchburg received technical assistance and paid for ads on Facebook. The Summer Passport participation in parks ranged from 120 to 875 children with participation in the free park lunch program doubling in Fitchburg. DISCUSSION: Key lessons learned are engage communication experts from each community at the beginning of the project, use text messaging components with in-person staff onsite to assist participants in the opt-in process, build momentum for a Facebook presence through purchasing Facebook advertisements, and partner with local park departments for programming. PMID- 29566577 TI - Self-Care Posters Serve as a Low-Cost Option for Physical Activity Promotion of Hospital Nurses. AB - Hospital nurses play an important role in the nation's short- and long-term patient care. At the same time, nurses often experience high levels of occupational stress and participate in low levels of physical activity (PA). The purpose of this study was to examine the impact of self-monitoring and a poster campaign on the PA behaviors of hospital nurses. Motivational and instructional exercise posters were hung in break rooms of experimental units and replaced biweekly for 8 weeks. A total of 26 nurses (control: n = 13; experimental: n = 13) wore accelerometers for 3 workdays pre-, mid-, and postintervention. Participants were provided a step counter at baseline and a PA report at each stage. Moderate to vigorous PA (MVPA) and step count (SC) increased pre- to midintervention for control (MVPA: 14.8 +/- 7.6%; SC: 19.1 +/- 7.8%) and experimental (MVPA: 26.7 +/- 18.5%, SC: 17.6 +/- 8.3%) participants. Physical activity levels returned to baseline postintervention for control ( p > .05) and increased mid- to postintervention for experimental (MVPA: 16.2 +/- 5.2%, SC: 10.7 +/- 4.7%, p < .05) participants. In conclusion, a low-cost, self-care poster campaign may increase PA levels of hospital nurses when combined with personalized PA feedback. PMID- 29566578 TI - Aminobenzisoxazole compounds as agonists of alpha7 nicotinic acetylcholine receptors: a patent evaluation (WO 2017027600). AB - INTRODUCTION: alpha 7 subtype nicotinic acetylcholine receptor (alpha7 nAChR) ligands, that is, ligands that interact with the orthosteric or allosteric binding sites of alpha7 nAChR, hold great potential for several therapeutic applications. Numerous compounds have been designed targeting alpha7 nAChR but most of them cannot be used therapeutically for various reasons. Areas covered: The patent application describes a series of germinal substituted aminobenzisoxazole compounds as alpha7 nAChR ligands. These compounds were claimed as potential therapeutics for treating and/or improving cognitive function. All of the (R)-stereoisomer presented high binding activities for alpha7 nAChR and several compounds displayed excellent selectivity over 5-HT3R. Expert opinion: The privileged structure-derived modification via bioisosterism and scaffold hopping is an important approach for seeking novel alpha7 nAChR ligands. The claimed germinal substituted aminobenzisoxazole derivatives with low tPSA values as well as low number of hydrogen bond donors and acceptors are supposed to have sufficient BBB penetration. Although there is a lack of essential biological data and the molecular mechanisms are not clear, these compounds stand for a new type of alpha7 nAChR ligands and deserve further studies. PMID- 29566579 TI - The effect of ocular lubricants containing benzalkonium chloride on nasal mucosal flora. AB - PURPOSE: The effect of ocular artificial teardrop containing benzalkonium chloride (BAC) on nasal mucosa was investigated. MATERIALS AND METHODS: There were two different treatment trial groups. Each dry eye syndrome (DES) patient received the ocular lubricant treatment four times a day in both groups (one group containing BAC, the other group was not). Moistened sterile cotton-tipped applicators were placed in both nostrils and were immediately cultured prior to ocular lubricant treatment and at the end of treatment trial. The bacterial culture-positivity rate, species of bacteria, and drug sensitivity were recorded in the two groups during pre-treatment and post-treatment. RESULTS: There were 20 patients in each group with a mean age of 53.14 years (36 female, 4 male). At the beginning of the treatment trial, Staphylococcus epidermidis was the most frequently isolated organism from the nasal cavity accounting in 24/40 patients (60%). Of the 40 organisms isolated from the nares prior to treatment trial, 37 (92.5%) were sensitive to gentamycin. At the end of 1 month of treatment trial in patients who were treated with ocular lubricants containing BAC, none of the nasal cultures showed growth of any organisms. However, patients who were treated with ocular lubricants not containing BAC demonstrated persistent positive nasal cultures with the same species and the same antibiotic susceptibility profile at the end of the treatment trial period. CONCLUSION: Topically applied ocular lubricants including BAC has an anti-bacterial activity on nasal flora in DES patients. PMID- 29566580 TI - Structural exploration of hydroxyethylamines as HIV-1 protease inhibitors: new features identified. AB - The current study deals with chemometric modelling strategies (Naive Bayes classification, hologram-based quantitative structure-activity relationship (HQSAR), comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA)) to explore the important features of hydroxylamine derivatives for exerting potent human immunodeficiency virus-1 (HIV 1) protease inhibition. Depending on the statistically validated reliable and robust quantitative structure-activity relationship (QSAR) models, important and crucial structural features have been identified that may be responsible for enhancing the activity profile of these hydroxylamine compounds. Arylsulfonamide function along with methoxy or fluoro substitution is important for enhancing activity. Bulky steric substitution at the sulfonamide nitrogen disfavours activity whereas smaller hydrophobic substitution at the same position is found to be favourable. Apart from the crucial oxazolidinone moiety, pyrrolidine, cyclic urea and methyl ester functions are also responsible for increasing the HIV-1 protease inhibitory profile. Observations derived from these modelling studies may be utilized further in designing promising HIV-1 protease inhibitors of this class. PMID- 29566581 TI - Investigation of bacteremia after debonding procedures. AB - OBJECTIVE: The purpose of this study is to investigate the effect of debonding procedures after completion of orthodontic treatments on bacteremia. MATERIALS AND METHODS: Twenty-eight patients who were treated with fixed orthodontic treatment at the Faculty of Dentistry's Department of Orthodontics at Gaziantep University and who had an indication of debonding were selected for this study, and blood samples were taken from these patients at different times and examined for bacteremia. Blood culture samples were taken from the antecubital veins of the patients prior to debonding (T0), immediately after removing the bracket (T1), and immediately after cleaning the composite residues and plaque deposits on the enamel surface (T2). The blood samples were then inoculated in blood culture bottles and investigated for bacterial growth. RESULTS: The results showed that there was no bacterial growth in the blood samples taken at T0 and T1, whereas 10 of the blood culture samples taken at T2 showed bacterial growth including the following bacteria; Streptococcus viridans, Streptococcus mitis, Streptococcus parasanguinis, Streptococcus salivarius, Streptococcus oralis, Staphylococcus aureus, Actinomyces oris, Actinomyces naeslundii and Klebsiella pneumoniae. CONCLUSION: It was concluded that patients in the risk group could develop bacteremia during debonding procedures. The presence of these bacteria in sterile blood suggested the possibility of bacterial endocarditis. PMID- 29566582 TI - Reducing mutans streptococci and caries development by Lactobacillus paracasei SD1 in preschool children: a randomized placebo-controlled trial. AB - OBJECTIVE: To examine a reducing effect of Lactobacillus paracasei SD1 on MS and caries in preschool children. MATERIALS AND METHODS: A total of 124 children, aged 1.5-5 years old, participated and were randomly assigned to the probiotic or control group. The probiotic group received L. paracasei SD1-milk and the control group received standard-milk once daily for 3 months. MS/lactobacilli were enumerated and the caries score was examined. Association between probiotic consumption and bacterial level, or caries progression was assessed by a multivariate logistic regression. This study was registered at the Thai-Clinical Trials-Registry (TCTR20140903001). RESULTS: Probiotic was found to be a factor associated with the MS level. Children in the probiotic group had a significantly lower risk of an increase in the MS level than in the control group after receiving the probiotic milk at 3- and 4-months with p < .001 and p = .040, respectively. Probiotic significantly reduced the risk for caries compared to the control group (p = .016). There were no adverse effects or non-compliance reported in either group. CONCLUSIONS: Consumption of milk powder containing L. paracasei SD1 resulted in a reduction of both salivary MS and delayed new caries development, and the strain is safe for use in young children. Results suggest that L. paracasei SD1 may be an alternative way for caries prevention in young children. PMID- 29566583 TI - Benefits of upgrading to the Nucleus(r) 6 sound processor for a wider clinical population. AB - OBJECTIVES: To determine whether a large clinical group of cochlear implant (CI) recipients demonstrated a difference in sentence recognition in noise when using their pre-upgrade sound processor compared to when using the Nucleus 6 processor, and to examine the impact of the following factors: implant type, sound processor type, age, or onset of hearing loss. METHODS: A file review of 154 CI recipients (aged 7-92 years old) who requested an upgrade to the Nucleus 6 sound processor at the Cochlear Care Centre Melbourne was conducted. 105 recipients had complete data collected according to the protocol. A repeated measures, single subject design was used. Performance of CI recipients was compared with their pre-upgrade sound processor versus the Nucleus 6 processor using the Australian Sentence Test in Noise. RESULTS: Group performance of CI recipients improved by 4.7 dB with the Nucleus 6 compared with the pre-upgrade sound processor. The benefit was not affected by pre-upgrade sound processor type or implant type (including older implant types and sound processors), age or onset of hearing loss (pre-lingual versus post-lingual). CONCLUSION: This study confirmed that a clinical group of CI recipients obtained a significant benefit when upgrading to the Nucleus 6 sound processor.

PMID- 29566585 TI - Evaluation of epidemiological, clinical, and laboratory features and mortality of 144 HIV/AIDS cases in Turkey. AB - Background The number of HIV/AIDS cases in Turkey is increasing rapidly, as is the number of cases worldwide. The aim of this study is to evaluate the characteristics of the clinical and laboratory findings and epidemiological features of HIV/AIDS patients to obtain useful data on the epidemic type and transmission routes associated with Turkey and to identify risk factors for mortality. Methods The patient records of 144 HIV-infected patients who were admitted to our clinic between 2000 and 2015 were analyzed retrospectively. Results Most of the cases (55%) were diagnosed due to the detection of anti-HIV positive individuals without clinical symptoms. The mean CD4 + lymphocyte count on first admission was 108 cells/MUL for those admitted before 2009 and 265 cells/MUL for those admitted after 2009 (p = 0.003). When the pre- and post-2009 groups were compared for the status of the disease, 55.6 and 44.4% of patients were in the AIDS stage, respectively (p = 0.04). The most noted opportunistic infection was mycobacterial, and throughout the follow-up, 31.2% of the cases were fatal. Conclusions Early diagnosis of HIV infection can have a direct impact on prognosis and survival. Therefore, screening laboratory investigations should be extended, particularly in high-risk groups. PMID- 29566586 TI - Efficacy and Safety of Basal Insulin/GLP-1 Receptor Agonist Used in Combination for Type 2 Diabetes Management. AB - PURPOSE: The purpose of this article is to review the efficacy, safety, and place in therapy of insulin degludec/liraglutide (IDegLira) and insulin glargine/lixisenatide (IGlarLixi) in the treatment of type 2 diabetes mellitus. SUMMARY: Type 2 diabetes is a condition affecting nearly 30 million American adults. Management of type 2 diabetes is complex and multifactorial. Using medications targeted at a variety of the physiologic defects known to contribute to the development of type 2 diabetes allows for a patient-specific approach to care. Utilizing combination products is a way to target several areas of the disease while decreasing the complexity and burden to the patient. Basal insulin/glucagon-like peptide-1 (GLP-1) agonist combination products have the benefit of being highly efficacious while having favorable effects on weight, reduced gastrointestinal adverse effects, and low hypoglycemic risks compared to the individual agents used alone. CONCLUSION: This article will review 2 basal insulin/GLP-1 agonist combination products, IDegLira and IGlarLixi, which were approved in November 2016. PMID- 29566588 TI - Effectiveness of ReSET; a strategic executive treatment for executive dysfunctioning in patients with Parkinson's disease. AB - In this multicentre randomised controlled trial (RCT), 43 patients with Parkinson's disease (PD) were randomly allocated to either the experimental condition receiving cognitive rehabilitation including strategy training (ReSET; Strategic Executive Treatment, n = 24) or to the control condition receiving computerised repetitive practice training for attention (Cogniplus, n = 16). We expected that strategy training (ReSET) would be more effective than cognitive training (Cogniplus) in improving patients' everyday life executive functioning. Neuropsychological assessment was administered at baseline, at 2 weeks and 3-5 months post-treatment. Primary outcome measure was the Role Resumption List (RRL). Secondary outcome measures were treatment goal attainment (TGA), Dysexecutive Questionnaire (DEX), Parkinson's Disease Questionnaire (PDQ-39), Zarit Burden Interview (ZBI) and neuropsychological tests. No effects of treatment were found on the primary outcome measure and on neuropsychological tests, except for one test of attention. At 2 weeks and 3-5 months post treatment, PD patients in both the ReSET and Cogniplus group reported a significant improvement in everyday life executive functioning, as measured with TGA and the DEX-self, with an advantage for ReSET only shortly after treatment. Given these results and that PD patients were able to adhere to these treatments despite their motor symptoms and fatigue (i.e., the drop-out rate was small), we conclude that both strategy training and cognitive training for impairments in EF might be beneficial and feasible for PD patients. PMID- 29566587 TI - Hypnosis as adjunct therapy to conscious sedation for venous access device implantation in breast cancer: A pilot study. AB - BACKGROUND: Recent reviews support that hypnosis has great potential for reducing pain and anxiety during mini-invasive surgery. Here, we assessed the feasibility of hypnotic induction session as adjunct therapy in conscious sedation for venous access device implantation. Primary outcomes were safety and patient satisfaction. METHODS: Thirty consecutive women with breast cancer were proposed adjunct of hypnosis before implantation under conscious sedation (midazolam: 0.5 mg +/- bolus of Ketamin: 5 mg on demand) indicated for chemotherapy. Self hypnosis was programmed and guided by one of two trained anesthesiologists. Implantation was performed by one of two experimented surgeons. It consisted of blind subclavian implantation of Braun ST 305 devices using a percutaneous technique adapted from Selinger's procedure. Clinical data were prospectively collected and retrospectively analyzed. A comprehensive custom-made questionnaire recorded patient satisfaction. RESULTS: In all, 30/30 patients consented to the procedure. The median age was 54 years (range: 35-77 years). The primary procedure was successful in 29/30. One case was converted into internal jugular vein access after a first attempt. Median length time of the implantation procedure in the operative room was 20 min (range: 10-60 min). Median length time in the recovery room preceding home discharge was 65 min (range: 15-185 min). None of the patients suffered complications. The satisfaction rate was >=90%, 27/30 patients would get hypnosis in case of reimplantation if necessary and 27/30 would recommend this procedure to others. CONCLUSION: Hypnosis under conscious sedation appears feasible and safe for port implantation under conscious sedation in cancer patients. Further studies would determine the exact value of hypnosis effectiveness. PMID- 29566589 TI - Obstructive sleep apnea and risk of aortic dissection: A meta-analysis of observational studies. AB - Objectives Obstructive sleep apnea acts as a potential risk factor for the development of cardiovascular disease. We undertook collaborative meta-analyses to clarify the risk of aortic dissection among adults suffering obstructive sleep apnea. Methods A systematic search of the databases (PubMed, Embase, and Cochrane Library) was performed. Studies reporting on the association between obstructive sleep apnea and aortic dissection were included. Information on 424 cases of aortic dissection in 56,291 patients from one cohort, four case-controls, and two cross-sectional studies were included in this study. Results The summary suggested that patients with obstructive sleep apnea are associated with an overall significant 60% increase in the risk of aortic dissection, compared to unexposed patients (odds ratios 1.60; 95% confidence interval 1.01-2.53), with a significantly higher apnea-hypopnea index (mean difference 10.71; 95% confidence interval 7.46-13.96). Moreover, a greater relation was found between moderate-to severe obstructive sleep apnea and aortic dissection (odds ratios 4.43; 95% confidence interval 2.59-7.59). Adverse outcomes obtained by sleep study such as oxygen desaturation index (mean difference 10.51; 95% confidence interval 7.54 13.48), average SaO2 (-1.36; 95% confidence interval -2.63 to -0.09), and minimum SaO2 (-3.63; 95% confidence interval -5.27 to -1.98) were correspondingly related to patients with aortic dissection. Conclusions Obstructive sleep apnea, especially moderate-to-severe obstructive sleep apnea, may impose an additional risk of suffering from aortic dissection with a potential mechanism including intermittent hypoxia. PMID- 29566591 TI - Malignant lymphoma with middle ear involvement in a Sprague-Dawley rat. AB - Sprague-Dawley rats are amongst the most widely used animals in biomedical research and malignant lymphoma has long been known to be a frequent neoplasm in these animals. A 9-month-old male control Sprague-Dawley rat from a toxicity study showed gelatinous material in the cranial cavity and dark, thickened cerebral meninges at necropsy. At microscopic evaluation of the temporal bone, neoplastic lymphocytes were seen invading several structures of the middle ear. The neoplastic cells appeared to extend from the marrow of the temporal bone, covered the dorsal part of the tympanic cavity wall, and surrounded and infiltrated the base of the tensor tympani muscle as well as the chorda tympani branch of the facial nerve. The lymphoma was generalized; neoplastic lymphocytes were also noted in numerous other tissues. Literature regarding neoplasms of the middle and inner ear in animals is scarce and, to our knowledge, this is the first report of a lymphoma involving the middle ear of a rat. PMID- 29566590 TI - The natural history of type 2 endoleaks after endovascular aneurysm repair justifies conservative management. AB - Objective Management of type 2 endoleaks after endovascular aneurysm repair has been controversial. Some advocate for conservative management, while others believe that intervention is indicated. This study investigated the natural history of type 2 endoleaks in order to derive direction in management. Methods Patients who had endovascular aneurysm repair at the Veterans Affairs Long Beach were retrospectively identified and computerized tomographic angiography was independently reviewed by a radiologist and a vascular surgeon. Type 2 endoleaks were analyzed for the following outcomes: rupture, duration of endoleak, spontaneous resolution, changes in the size of the aneurysm sac, and reintervention rates. Results Of the 160 patients who had completed required follow-up to date (mean 3 years) after endovascular aneurysm repair, 39 (24.4%) patients were identified as having a type 2 endoleak on computerized tomographic angiography imaging. 6 (15.4%) of these 39 patients required repair due to aneurysm sac growth >1 cm. 2 (5.13%) were repaired with an open procedure and 4 (10.3%) with an endovascular approach. Of these 6 aneurysm leaks requiring repair, 4 (66.7%) had a simultaneous endoleak (types 1 or 3) in addition to the identified type 2 endoleak. Spontaneous resolution of type 2 endoleaks occurred in 16 (41.0%) patients. 4 patients (10.3%) had delayed type 2 endoleaks that presented 4, 9, 12, and 23 months after their 30 day post op computed tomography was normal. None of the 4 patients with delayed type 2 endoleaks required reintervention and none had aneurysm sac growth greater than 5 mm. Conclusions Overall, we found that 85% of patients who had type 2 endoleaks did not require intervention after a mean follow-up time of 3 years. The association of a type 1 or 3 endoleak with a type 2 endoleak was more likely to require correction due to aneurysm expansion >1 cm, thus type 2 endoleaks associated with another type of endoleak require more aggressive management. PMID- 29566592 TI - Age-Friendly Communities and Life Satisfaction Among the Elderly in Urban China. AB - This study aims to examine the extent to which older adults' perceptions of environmental age-friendliness are associated with their life satisfaction. We used a national representative sample ( N = 9,965) with elders aged 60 and above from urban China and structural equation modeling to analyze the relationship among community characteristics, socioeconomic status (SES), and life satisfaction. Results showed that older people's perceptions of housing conditions, local amenities, and social inclusion were significantly associated with general life satisfaction. Multigroup comparison tests indicated that no disparities in the aforementioned relationships among SES subgroups. However, the socioeconomically disadvantaged elderly population was shown to have the lowest assessment of community age-friendliness. Findings emphasized the potential role of age-friendly communities as having an influential force on older adults' subjective well-being, regardless of their SES. Meanwhile, policy makers and practitioners should pay special attentions to improve the living environments of disadvantaged elders. PMID- 29566593 TI - Selective Vulnerability of the Foramen Magnum in a Rat Blast Traumatic Brain Injury Model. AB - Primary blast traumatic brain injury (bTBI) accounts for a significant proportion of wartime trauma. Previous studies have demonstrated direct brain injury by blast waves, but the effect of the location of the blast epicenter on the skull with regard to brain injury remains poorly characterized. In order to investigate the role of the blast epicenter location, we modified a previously established rodent model of cranium-only bTBI to evaluate two specific blast foci: a rostrally focused blast centered on bregma (B-bTBI), which excluded the foramen magnum region, and a caudally focused blast centered on the occipital crest, which included the foramen magnum region (FM-bTBI). At all blast overpressures studied (668-1880 kPa), rats subjected to FM-bTBI demonstrated strikingly higher mortality, increased durations of both apnea and hypoxia, and increased severity of convexity subdural hematomas, than rats subjected to B-bTBI. Together, these data suggest a unique role for the foramen magnum region in mortality and brain injury following blast exposure, and emphasize the importance of the choice of blast focus location in experimental models of bTBI.

AB - The crude divorce rate has been increasing steadily for over a decade in China. Consequently, more and more children have to face the challenge of growing up in single parent families. The current study investigated the mediating effects of problem-oriented and emotion-oriented coping on the relationship between parental attachment and psychological resilience among a sample of Chinese adolescents from single parent families and intact families. Participants were 975 high school students (44.30% males; aged 15-19 years, M = 16.32 years, SD = 0.74), 871 from intact families and 104 from single parent families. Structural equation modeling showed that security in maternal attachment was positively associated with resilience through the indirect effect of reduced emotion-oriented coping among adolescents from single parent families. Among adolescents from intact families, security in maternal attachment was both directly associated with resilience and indirectly through enhanced problem-oriented and reduced emotion oriented coping. Security in paternal attachment was associated with resilience both directly and indirectly through enhanced problem-oriented coping as well among those from intact families. Female adolescents exhibited significantly lower levels of resilience than male adolescents did regardless of the marital status of their parents. Limitations and suggestions for future research are discussed. PMID- 29566595 TI - 15-Year Secular Trends in Cognitive Function Among Older Adults in the United States. AB - Cognitive impairment is associated with various chronic diseases, including mobility limitation and early mortality. Thus, evaluating changes in cognition is of paramount public health interest. The purpose of this study was to evaluate secular trends in cognitive function among a representative sample of the U.S. older adult population. Data from the 1999-2000, 2001-2002, 2011-2012, and 2013 2014 National Health and Nutrition Examination Survey were utilized to identify an aggregate sample of adults 60+ years of age. The sample size across the four respective cycles was 1417, 1558, 1422, and 1592. Three cognitive assessments were employed, including the CERAD Word Learning subset (Consortium to Establish a Registry for Alzheimer's disease), the Animal Fluency test, and the Digit Symbol Substitution Test (DSST). For the entire sample and several subpopulations, DSST scores increased from 1999 to 2012 and then decreased in the 2013 to 2014 cycle. For all CERAD trials, there was evidence of increased CERAD performance from 2011-2012 to 2013-2014. No secular trends were observed for the Animal Fluency task across these cycles. Select cognitive parameters appear to be improving among U.S. older adults. Future work is needed to further explore secular trends in cognitive sustainability, and, as evidenced by our present study, cognitive enrichment over time. PMID- 29566596 TI - Assessment Tools for Peripheral Neuropathy in Pediatric Oncology: A Systematic Review From the Children's Oncology Group. AB - Peripheral neuropathy is a known side effect of several chemotherapy agents, including vinca alkaloids and platinum-based chemotherapy. Early recognition and monitoring of this side effect is an important role of the pediatric oncology nurse. There are a variety of peripheral neuropathy assessment tools currently in use, but the usefulness of these tools in identifying and grading neuropathy in children varies, and there is currently no standardized tool in place to evaluate peripheral neuropathy in pediatric oncology. A systematic review was performed to identify the peripheral neuropathy assessment tools that best evaluate the early onset and progression of peripheral neuropathy in pediatric patients receiving vincristine. Because of the limited information available in pediatric oncology, this review was extended to any pediatric patient with neuropathy. A total of 8 studies were included in the evidence synthesis. Based on available evidence, the pediatric-modified Total Neuropathy Scale (ped-m TNS) and the Total Neuropathy Score-pediatric version (TNS-PV) are recommended for the assessment of vincristine-induced peripheral neuropathy in children 6 years of age and older. In addition, several studies demonstrated that subjective symptoms alone are not adequate to assess for vincristine-induced peripheral neuropathy. Nursing assessment of peripheral neuropathy should be an integral and regular part of patient care throughout the course of chemotherapy treatment. PMID- 29566597 TI - Depression in the First Year after Traumatic Brain Injury. AB - The aims of this study were to document the frequency of major and minor depressive episodes in the first year after traumatic brain injury (TBI), taking into account TBI severity and pre-morbid history of major depression, and to describe trajectories of depressive episodes. Participants were 227 adults who were hospitalized post-TBI (76% male; mean age = 41 years; 50% mild, 33% moderate, and 17% severe TBI). Major and minor depressive episodes were assessed with the Mini International Neuropsychiatric Interview at three time points (4, 8, and 12 months after TBI). Overall, 29% of participants had a major depressive episode in at least one of the three assessments, with fairly stable rates across assessments. Participants with mild TBI were more likely than those with moderate/severe TBI to be diagnosed with major depression, as were individuals with a positive pre-morbid history of depression compared to those without such history. In addition, 13% of participants had a minor depressive episode in at least one of the three assessments. Rates of minor depression significantly decreased from 4 to 8-12 months post-injury. Results also revealed a wide variety of trajectories of depressive episodes across assessments. Of note, 52% of major depression cases still fulfilled diagnostic criteria 4 months later, whereas 38% of minor depression cases deteriorated to major depression at the following assessment. These findings suggest that depression is highly prevalent after TBI, and monitoring of patients with subthreshold depressive symptoms is warranted in order to prevent the development of full-blown major depressive episodes. PMID- 29566598 TI - Validation study of the Alzheimer's disease assessment scale-cognitive subscale (ADAS-Cog) for the Portuguese patients with mild cognitive impairment and Alzheimer's disease. AB - OBJECTIVE: The Alzheimer's disease assessment scale-Cognitive Subscale (ADAS-Cog) is a battery to assess cognitive performance in Alzheimer's disease (AD) and was developed according to the core characteristics of cognitive decline in AD: memory, language, praxis, constructive ability, and orientation. The aim of this study was to explore the diagnostic accuracy and discriminative capacity of the ADAS-Cog for Mild Cognitive Impairment (MCI) and AD, using cut-off points for the Portuguese population. METHOD: The European Portuguese version of the ADAS-Cog was administrated to 650 participants, divided into a control group (n = 210), an MCI group (n = 240), and an AD group (n = 200). The clinical groups fulfilled standard international diagnostic criteria. Controls were healthy cognitive participants actively integrated in the community. The neuropsychological assessment protocol included the ADAS-Cog, the Mini Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), and the Adults and Older Adults Functional Assessment Inventory (IAFAI). RESULTS: The ADAS-Cog revealed good psychometric indicators, and the total scores were significantly different between the three groups (p < .001: Control < MCI < AD). The optimal cut-off points established were: MCI > 9 points (AUC = .835; sensitivity = 58% and specificity = 91%) and AD > 12 points (AUC = .996; sensitivity = 94% and specificity = 98%). CONCLUSIONS: Our findings confirmed the capacity of the ADAS Cog total score to identify cognitive impairment in AD patients, with poor sensitivity for MCI, in a Portuguese cohort. PMID- 29566599 TI - Synergistic effects of rmhTRAIL and 17-AAG on the proliferation and apoptosis of multiple myeloma cells. AB - OBJECTIVE: This study aimed to investigate synergistic effects of recombinant mutant human tumor necrosis factor-related apoptosis-inducing ligand (rmhTRAIL) and heat-shock protein 90 (HSP90) inhibitor (geldanamycin derivative 17 allylamino- 17-demethoxy -geldanamycin, 17-AAG) on the proliferation and apoptosis of multiple myeloma (MM) cells. METHODS: MTT assays evaluated inhibitory effects of rmhTRAIL and 17-AAG in different concentrations and treatment durations on the proliferation of RPMI8226 and U266 cells. The half maximal inhibitory concentration was calculated using OriginPro7.5. Synergistic effects of rmhTRAIL and 17-AAG on apoptosis of MM cells were detected using flow cytometry at 24 and 48 h post-treatment. To evaluate synergistic effects of rmhTRAIL and 17-AAG, the Q-value was calculated using King's formula. RESULTS: rmhTRAIL exhibited significant inhibitory effects on the proliferation of RPMI8226 cells in a dose- and time-dependent manner (>50%), whereas U266 cells were not sensitive to rmhTRAIL (<50%). 17-AAG inhibited the proliferation of RPMI8226 and U266 cells in a dose-dependent manner (>80%). Significant synergistic effects of rmhTRAIL and 17-AAG on the proliferation of RPMI8226 cells were revealed (Q-value > 1.15), whereas synergistic effects were not evident on the proliferation of U266 cells (Q-value < 1.15). rmhTRAIL and 17-AAG exhibited significant synergistic effects on apoptosis of RPMI8226 and U266 cells (Q-value > 1.15). CONCLUSION: The combined application of rmhTRAIL and 17-AAG revealed favorable synergistic effects in the treatment of MM. PMID- 29566600 TI - Predicting Long-Term Global Outcome after Traumatic Brain Injury: Development of a Practical Prognostic Tool Using the Traumatic Brain Injury Model Systems National Database. AB - For patients surviving serious traumatic brain injury (TBI), families and other stakeholders often desire information on long-term functional prognosis, but accurate and easy-to-use clinical tools are lacking. We aimed to build utilitarian decision trees from commonly collected clinical variables to predict Glasgow Outcome Scale (GOS) functional levels at 1, 2, and 5 years after moderate to-severe closed TBI. Flexible classification tree statistical modeling was used on prospectively collected data from the TBI-Model Systems (TBIMS) inception cohort study. Enrollments occurred at 17 designated, or previously designated, TBIMS inpatient rehabilitation facilities. Analysis included all participants with nonpenetrating TBI injured between January 1997 and January 2017. Sample sizes were 10,125 (year-1), 8,821 (year-2), and 6,165 (year-5) after cross sectional exclusions (death, vegetative state, insufficient post-injury time, and unavailable outcome). In our final models, post-traumatic amnesia (PTA) duration consistently dominated branching hierarchy and was the lone injury characteristic significantly contributing to GOS predictability. Lower-order variables that added predictability were age, pre-morbid education, productivity, and occupational category. Generally, patient outcomes improved with shorter PTA, younger age, greater pre-morbid productivity, and higher pre-morbid vocational or educational achievement. Across all prognostic groups, the best and worst good recovery rates were 65.7% and 10.9%, respectively, and the best and worst severe disability rates were 3.9% and 64.1%. Predictability in test data sets ranged from C-statistic of 0.691 (year-1; confidence interval [CI], 0.675, 0.711) to 0.731 (year-2; CI, 0.724, 0.738). In conclusion, we developed a clinically useful tool to provide prognostic information on long-term functional outcomes for adult survivors of moderate and severe closed TBI. Predictive accuracy for GOS level was demonstrated in an independent test sample. Length of PTA, a clinical marker of injury severity, was by far the most critical outcome determinant. PMID- 29566602 TI - A Comparison of Intimate Partner Violence Strangulation Between Same-Sex and Different-Sex Couples. AB - Strangulation is a common and dangerous form of intimate partner violence (IPV). Nonfatal strangulation is a risk factor for homicide; can lead to severe, long term physical and mental health sequelae; and can be an effective strategy of coercion and control. To date, research has not examined strangulation within same-sex couples. The objective of this cross-sectional, observational research is to identify whether and to what extent the detection of strangulation and coercive control differs between same-sex and different-sex couples in police reports of IPV. Data ( n = 2,207) were obtained from a single police department in the southwest United States (2011-2013). Bivariate analyses examined differences in victim and offender demographics, victim injury, violence, and coercive controlling behaviors between same-sex (male-male and female-female) and different-sex couples (female victim-male offender). Logistic regression was used to examine associations between strangulation, victim and offender demographics, coercive controlling behaviors, and couple configuration. Strangulation was reported significantly more often in different-sex (9.8%) than in female and male same-sex couple cases (5.2% and 5.3%, respectively; p < .05). Injury, however, was reported more frequently in same-sex than in different-sex couples ( p < .05). Couple configuration ( p < .05), coercive control ( p < .05), and injury ( p < .05) significantly predict strangulation. Findings suggest that nonfatal strangulation occurs within at least a minority of same-sex couples; it is possible that underdetection by law enforcement makes it appear less common than it actually is. Regardless of couple configuration, timely identification of strangulation and subsequent referral to medical and social service providers is essential for preventing repeated strangulation, life-threatening injury, and the long-term health effects of strangulation. PMID- 29566603 TI - Did I Help Get Us Here? PMID- 29566601 TI - Investigation of Microbiota Alterations and Intestinal Inflammation Post-Spinal Cord Injury in Rat Model. AB - Although there has been a significant amount of research focused on the pathophysiology of spinal cord injury (SCI), there is limited information on the consequences of SCI on remote organs. SCI can produce significant effects on a variety of organ systems, including the gastrointestinal tract. Patients with SCI often suffer from severe, debilitating bowel dysfunction in addition to their physical disabilities, which is of major concern for these individuals because of the adverse impact on their quality of life. Herein, we report on our investigation into the effects of SCI and subsequent antibiotic treatment on the intestinal tissue and microbiota. For that, we used a thoracic SCI rat model and investigated changes to the microbiota, proinflammatory cytokine levels, and bacterial communication molecule levels post-injury and gentamicin treatment for 7 days. We discovered significant changes, the most interesting being the differences in the gut microbiota beta diversity of 8-week SCI animals compared to control animals at the family, genus, and species level. Specifically, 35 operational taxonomic units were enriched in the SCI animal group and three were identified at species level; Lactobacillus intestinalis, Clostridium disporicum, and Bifidobacterium choerinum. In contrast, Clostridium saccharogumia was identified as depleted in the SCI animal group. Proinflammatory cytokines interleukin (IL)-12, macrophage inflammatory protein-2 (MIP-2), and tumor necrosis factor alpha were found to be significantly elevated in intestinal tissue homogenate 4 weeks post-SCI compared to 8-weeks post-injury. Further, levels of IL-1beta, IL-12, and MIP-2 significantly correlated with changes in beta diversity 8-weeks post-SCI. Our data provide a greater understanding of the early effects of SCI on the microbiota and gastrointestinal tract, highlighting the need for further investigation to elucidate the mechanism underlying these effects.

AB - Coxiella burnetii is an obligate intracellular pathogen and the cause of Q fever in many animal species and humans. Several studies have reported the association between C. burnetii and abortion, premature delivery, stillbirth, and weak offspring. However, no solid evidence indicates that C. burnetii causes endometritis, subfertility, and retained fetal membranes. For this study, histopathological and PCR evaluation were performed on 40 uterine biopsies from dairy cattle with poor fertility. Uterine swabs were concurrently tested with microbiology assays. The endometrial biopsies of 30 cows did not have any significant lesions, and no pathogens were identified by aerobic bacterial culture and PCR. Ten cows were PCR-positive for C. burnetii and negative for other pathogens by aerobic bacterial culture and PCR. These 10 cases revealed a mild to severe chronic endometritis admixed with perivascular and periglandular fibrosis. Immunohistochemical evaluation of C. burnetii PCR-positive biopsies identified, for the first time, the presence of intralesional and intracytoplasmic C. burnetii in macrophages in the endometrium of cattle. PMID- 29566609 TI - DNA Methylation Status of the Estrogen Receptor alpha Gene in Canine Mammary Tumors. AB - Estrogen receptor alpha (ERalpha) has an important role in mammary carcinogenesis, prognosis, and treatment. In human and canine mammary cancer, the most aggressive tumors show loss of ERalpha expression, which in human breast cancer has been attributed to methylation of the cytosine followed by guanine (CpG) island within the estrogen receptor alpha gene ( ESR1) promoter. This study aimed to investigate the role of ESR1 CpG island (CGI) methylation in ERalpha expression in canine mammary tumors. Twenty-one canine mammary samples were sorted into three groups: malignant tumor (n = 9), benign tumor (n = 8), and normal gland (n = 4). Immunohistochemical analysis and reverse-transcription quantitative real-time PCR were performed to assess ERalpha expression and ESR1 mRNA levels. The methylation status was determined using sodium-bisulfite-treated DNA sequencing. All normal mammary glands and benign tumors showed high ERalpha expression (score range, 5-8). Six of the nine malignant tumors did not show ERalpha expression (score 0), two had score 2, and one had score 4. Lower ERalpha ( P < .005) and ESR1 mRNA levels ( P < .005) were found in malignant mammary tumors than in the other two groups. Canine ESR1 has an intragenic and non promoter-associated CGI, different from humans. No significant variation in methylation percentage was observed among the groups, suggesting that ESR1 is not regulated by DNA methylation, unlike that in humans. This difference should be considered in further research using ERalpha as a biomarker for mammary tumors in canine studies on ERalpha-targeting therapy. PMID- 29566610 TI - Histologic Changes Associated With Placental Separation in Gilts Infected with Porcine Reproductive and Respiratory Syndrome Virus. AB - The placenta is a vital organ providing the developing fetus with nutrient and gas exchange, thermoregulation, and waste elimination necessary for fetal development, as well as producing hormones to maintain pregnancy. It is hypothesized that fetal pig death in porcine reproductive and respiratory syndrome may be attributed to pathology of the maternal-fetal interface leading to premature placental separation. This study was designed to evaluate the chronologic progression of porcine reproductive and respiratory syndrome virus (PRRSV)-induced lesions at the maternal-fetal interface, with particular focus on placental separation in experimentally challenged third-trimester gilts. Fifteen gilts were inoculated with a virulent strain of PRRSV-2 on gestation day 86 +/- 0.4. On multiple days postinoculation, 3 gilts along with 1 sham-inoculated control per time point were euthanized, and uterine and fetal placental tissues corresponding to each fetus were collected for histopathologic evaluation. The presence of any fetal lesion was 23 times more likely in compromised (meconium stained and decomposed) compared with viable fetuses ( P < .001). In PRRSV infected gilts, endometritis was more severe than placentitis, and the severity of endometrial inflammation and vasculitis increased progressively from 2 to 14 days postinoculation. Neither placental vasculitis nor a chronologic progression in the severity of placental detachment was observed. Severe placental detachment was more frequently present in PRRSV-infected compared with noninfected samples and was most significantly associated with placental inflammation, compared with other uterine lesions, viral load, or termination day. The results of this study suggest that placental separation by itself is not sufficient to significantly compromise fetal viability in reproductive porcine reproductive and respiratory syndrome. PMID- 29566611 TI - Treatment of HCV in the Department of Corrections in the Era of Oral Medications. AB - Chronic hepatitis C virus (HCV) is widely prevalent in the Virginia Department of Corrections (DOC). However, sustained virologic response (SVR) with all oral direct-acting antiviral (DAA) therapy is unknown. HCV treatment was provided through telemedicine following guidelines of the American Association for the Study of Liver Diseases and Infectious Diseases Society of America. SVR12 in the DOC was compared in two control groups: privately insured and indigent patients receiving care in HCV treatment clinics by the same providers during the same time period. Of 220 DOC patients, 180 were started on therapy (158 genotype [GT] 1, 15 GT2, and 10 GT3). SVR12 data on GT1 patients who received ledipasvir/sofosbuvir with or without ribavirin (RBV) were 96%, similar to our indigent (95%) and private clinic (93%) patients despite differences in age, gender, treatment experience, FIB-4, and use of RBV. Multiple logistic regression of GT1 patients identified lower FIB-4 ( p = .008) and treatment clinic ( p = .01) as independent predictors of SVR12. HCV treatment in the DOC by telemedicine with DAA is not only feasible but has a very high SVR12 similar to published trials. PMID- 29566614 TI - Love and Responsibility: A New Understanding of Leadership. AB - The purpose of the study is to investigate the importance of substance for the disclosure of ontological evidence. The methodology is inspired by Gadamer's hermeneutic philosophy and involves clinical application research using a deductive approach. This means that leaders in a clinical context were taught and participated in a discussion about a theoretical model of leadership with caring science and ontological substance. The result shows that the leaders' attention and focus were primarily directed toward administration, finances, and outer structures. Caring science and ontological substance contributed toward disclosing ontological evidence, and leadership emerged as caring, love, inner responsibility, guilt, and vulnerability. In this study, substance has been combined with teaching and group discussion as a methodical approach. Substance is the guiding issue and has been shown to lead to truth. The method is in a true sense nothing without substance. PMID- 29566615 TI - Hidden Figures: A Humanbecoming Movie Review. PMID- 29566616 TI - Toward Understanding Through Hermeneutic Letterwriting.

The hermeneutic methodology is inspired by Hans Georg Gadamer. Hermeneutic letterwriting in accordance with Gadamer's thought is a form of dialogue in writing, where what is truthful about the thing itself is unveiled with the help of the language. Hermeneutic letterwriting is presented in five steps. As a method, hermeneutic letterwriting is appropriate for complex caring science issues, and it offers new opportunities for attaining a deeper understanding of the world of caring.

AB - Caring is considered a unique concept in nursing because it subsumes all intrinsic attributes of nursing as a human helping discipline. Scholars have argued that caring is usually seen as an encounter between nurses and patients, but how about nurses with minimal or absent nurse-patient encounters, like informatics nurses? In this study, we explored the meaning of the phenomenon of caring to present lived experiences of caring, namely caring as actions of coming in between; caring as expressed within embodied relations; and caring and the path traversed by informatics nurses. The informatics nurse-cyborg-patient triad speaks of Filipino informatics nurses' insightful understanding of the phenomenon of caring.

The living experience of suffering is discussed in relation to the principles of the humanbecoming paradigm and in relation to further research inquiries. PMID- 29566612 TI - Defeating Cancers' Adaptive Defensive Strategies Using Thermal Therapies: Examining Cancer's Therapeutic Resistance, Ablative, and Computational Modeling Strategies as a means for Improving Therapeutic Outcome. AB - BACKGROUND: Diverse thermal ablative therapies are currently in use for the treatment of cancer. Commonly applied with the intent to cure, these ablative therapies are providing promising success rates similar to and often exceeding "gold standard" approaches. Cancer-curing prospects may be enhanced by deeper understanding of thermal effects on cancer cells and the hosting tissue, including the molecular mechanisms of cancer cell mutations, which enable resistance to therapy. Furthermore, thermal ablative therapies may benefit from recent developments in computer hardware and computation tools for planning, monitoring, visualization, and education. METHODS: Recent discoveries in cancer cell resistance to destruction by apoptosis, autophagy, and necrosis are now providing an understanding of the strategies used by cancer cells to avoid destruction by immunologic surveillance. Further, these discoveries are now providing insight into the success of the diverse types of ablative therapies utilized in the clinical arena today and into how they directly and indirectly overcome many of the cancers' defensive strategies. Additionally, the manner in which minimally invasive thermal therapy is enabled by imaging, which facilitates anatomical features reconstruction, insertion guidance of thermal probes, and strategic placement of thermal sensors, plays a critical role in the delivery of effective ablative treatment. RESULTS: The thermal techniques discussed include radiofrequency, microwave, high-intensity focused ultrasound, laser, and cryosurgery. Also discussed is the development of thermal adjunctive therapies the combination of drug and thermal treatments-which provide new and more effective combinatorial physical and molecular-based approaches for treating various cancers. Finally, advanced computational and planning tools are also discussed. CONCLUSION: This review lays out the various molecular adaptive mechanisms-the hallmarks of cancer-responsible for therapeutic resistance, on one hand, and how various ablative therapies, including both heating- and freezing based strategies, overcome many of cancer's defenses, on the other hand, thereby enhancing the potential for curative approaches for various cancers.

AB - In the digital polymerase chain reaction (dPCR) detection process, discriminating positive droplets from negative ones directly affects the final concentration and is one of the most important factors affecting accuracy. Current automated classification methods usually discuss single-channel detections, whereas duplex detection experiments are less discussed. In this paper, we designed a classification method by estimating the upper limit of the negative droplets. The right tail of the negative droplets is approximated using a generalized Pareto distribution. Furthermore, our method takes fluorescence compensation in duplex assays into account. We also demonstrate the method on Bio-Rad's mutant detection dataset. Experimental results show that the method provides similar or better accuracy than other algorithms reported over a wider dynamic range. PMID- 29566637 TI - Integrating virtual screening and biochemical experimental approach to identify potential anti-cancer agents from drug databank. AB - Chemical libraries constitute a reservoir of pharmacophoric molecules to identify potent anti-cancer agents. Virtual screening of heterocyclic compound library in conjugation with the agonist-competition assay, toxicity-carcinogenicity analysis, and string-based structural searches enabled us to identify several drugs as potential anti-cancer agents targeting protein kinase C (PKC) as a target. Molecular modeling study indicates that Cinnarizine fits well within the PKC C2 domain and exhibits extensive interaction with the protein residues. Molecular dynamics simulation of PKC-Cinnarizine complex at different temperatures (300, 325, 350, 375, and 400[Formula: see text]K) confirms that Cinnarizine fits nicely into the C2 domain and forms a stable complex. The drug Cinnarizine was found to bind PKC with a dissociation constant Kd of [Formula: see text]M. The breast cancer cells stimulated with Cinnarizine causes translocation of PKC-[Formula: see text] to the plasma membrane as revealed by immunoblotting and immunofluorescence studies. Cinnarizine also dose dependently reduced the viability of MDAMB-231 and MCF-7 breast cancer cells with an IC[Formula: see text] of [Formula: see text] and [Formula: see text]g/mL, respectively. It is due to the disturbance of cell cycle of breast cancer cells with reduction of S-phase and accumulation of cells in G1-phase. It disturbs mitochondrial membrane potentials to release cytochrome C into the cytosol and activates caspase-3 to induce apoptosis in cancer cells. The cell death was due to induction of apoptosis involving mitochondrial pathway. Hence, the current study has assigned an additional role to Cinnarizine as an activator of PKC and potentials of the approach to identify new molecules for anti-cancer therapy. Thus, in silico screening along with biochemical experimentation is a robust approach to assign additional roles to the drugs present in the databank for anti cancer therapy.

AB - The accurate detection of genomic islands (GIs) in microbial genomes is important for both evolutionary study and medical research, because GIs may promote genome evolution and contain genes involved in pathogenesis. Various computational methods have been developed to predict GIs over the years. However, most of them cannot make full use of GI-associated features to achieve desirable performance. Additionally, many methods cannot be directly applied to newly sequenced genomes. We develop a new method called GI-Cluster, which provides an effective way to integrate multiple GI-related features via consensus clustering. GI-Cluster does not require training datasets or existing genome annotations, but it can still achieve comparable or better performance than supervised learning methods in comprehensive evaluations. Moreover, GI-Cluster is widely applicable, either to complete and incomplete genomes or to initial GI predictions from other programs. GI-Cluster also provides plots to visualize the distribution of predicted GIs and related features. GI-Cluster is available at https://github.com/icelu/GI_Cluster. PMID- 29566639 TI - Integrative analysis of gene expression and DNA methylation using unsupervised feature extraction for detecting candidate cancer biomarkers. AB - Currently, cancer biomarker discovery is one of the important research topics worldwide. In particular, detecting significant genes related to cancer is an important task for early diagnosis and treatment of cancer. Conventional studies mostly focus on genes that are differentially expressed in different states of cancer; however, noise in gene expression datasets and insufficient information in limited datasets impede precise analysis of novel candidate biomarkers. In this study, we propose an integrative analysis of gene expression and DNA methylation using normalization and unsupervised feature extractions to identify candidate biomarkers of cancer using renal cell carcinoma RNA-seq datasets. Gene expression and DNA methylation datasets are normalized by Box-Cox transformation and integrated into a one-dimensional dataset that retains the major characteristics of the original datasets by unsupervised feature extraction methods, and differentially expressed genes are selected from the integrated dataset. Use of the integrated dataset demonstrated improved performance as compared with conventional approaches that utilize gene expression or DNA methylation datasets alone. Validation based on the literature showed that a considerable number of top-ranked genes from the integrated dataset have known relationships with cancer, implying that novel candidate biomarkers can also be acquired from the proposed analysis method. Furthermore, we expect that the proposed method can be expanded for applications involving various types of multi omics datasets. PMID- 29566640 TI - Principal component analysis in protein tertiary structure prediction. AB - We discuss applicability of principal component analysis (PCA) for protein tertiary structure prediction from amino acid sequence. The algorithm presented in this paper belongs to the category of protein refinement models and involves establishing a low-dimensional space where the sampling (and optimization) is carried out via particle swarm optimizer (PSO). The reduced space is found via PCA performed for a set of low-energy protein models previously found using different optimization techniques. A high frequency term is added into this expansion by projecting the best decoy into the PCA basis set and calculating the residual model. This term is aimed at providing high frequency details in the energy optimization. The goal of this research is to analyze how the dimensionality reduction affects the prediction capability of the PSO procedure. For that purpose, different proteins from the Critical Assessment of Techniques for Protein Structure Prediction experiments were modeled. In all the cases, both the energy of the best decoy and the distance to the native structure have decreased. Our analysis also shows how the predicted backbone structure of native conformation and of alternative low energy states varies with respect to the PCA dimensionality. Generally speaking, the reconstruction can be successfully achieved with 10 principal components and the high frequency term. We also provide a computational analysis of protein energy landscape for the inverse problem of reconstructing structure from the reduced number of principal components, showing that the dimensionality reduction alleviates the ill-posed character of this high-dimensional energy optimization problem. The procedure explained in this paper is very fast and allows testing different PCA expansions. Our results show that PSO improves the energy of the best decoy used in the PCA when the adequate number of PCA terms is considered. PMID- 29566641 TI - Imagining the Future in Children with Severe Traumatic Brain Injury. AB - Imagining future events is thought to rely on recombination and integration of past episodic memory traces into future events. Future and past events contain episodic and nonepisodic details. Children with severe traumatic brain injury (TBI) were found to have impaired recall of past episodic (but not semantic) event details. Here, we examined whether severe TBI impairs construction of future events. Children with severe TBI (n = 15) and healthy controls (NC; n = 33) 1) completed tests of anterograde (narrative and relational) memory and executive skills, 2) recalled past events and generated future events, and 3) rated events' phenomenological qualities. Events were scored for episodic (internal) and semantic (external) details. The groups did not differ in generating details of future events, although children with TBI recalled significantly fewer past internal (but not external) events' details relative to NCs. Moreover, the number of past internal details relative to future internal details was significantly higher in the NC group, but not in the TBI groups. Significant correlations between past and future were found for 1) internal details in both groups and 2) external details in the NC group. The TBI group rated their events as being less significant than did the NC group. The groups did not differ on ratings of visual intensity and rehearsal. Our study has shown that children who have sustained severe TBI had impoverished recall of past, but not generation of future, events. This unexpected dissociation between past and future event construction requires further research. PMID- 29566642 TI - The Ongoing U.S. Health Care Crisis: A Data Update. AB - While efforts to repeal the Affordable Care Act were narrowly defeated, grave problems in health care persist. Twenty-eight million remain uninsured, a number that is likely to increase. Millions more who have coverage cannot afford care because of high cost-sharing requirements. Meanwhile, the corporate takeover of medical care in the United States is at a gallop. This article provides a brief precis of recent data on U.S. health policy. PMID- 29566643 TI - Genomic selection signatures in sheep from the Western Pyrenees. AB - BACKGROUND: The current large spectrum of sheep phenotypic diversity results from the combined product of sheep selection for different production traits such as wool, milk and meat, and its natural adaptation to new environments. In this study, we scanned the genome of 25 Sasi Ardi and 75 Latxa sheep from the Western Pyrenees for three types of regions under selection: (1) regions underlying local adaptation of Sasi Ardi semi-feral sheep, (2) regions related to a long traditional dairy selection pressure in Latxa sheep, and (3) regions experiencing the specific effect of the modern genetic improvement program established for the Latxa breed during the last three decades. RESULTS: Thirty-two selected candidate regions including 147 annotated genes were detected by using three statistical parameters: pooled heterozygosity H, Tajima's D, and Wright's fixation index Fst. For Sasi Ardi sheep, chromosomes Ovis aries (OAR)4, 6, and 22 showed the strongest signals and harbored several candidate genes related to energy metabolism and morphology (BBS9, ELOVL3 and LDB1), immunity (NFKB2), and reproduction (H2AFZ). The major genomic difference between Sasi Ardi and Latxa sheep was on OAR6, which is known to affect milk production, with highly selected regions around the ABCG2, SPP1, LAP3, NCAPG, LCORL, and MEPE genes in Latxa sheep. The effect of the modern genetic improvement program on Latxa sheep was also evident on OAR15, on which several olfactory genes are located. We also detected several genes involved in reproduction such as ESR1 and ZNF366 that were affected by this selection program. CONCLUSIONS: Natural and artificial selection have shaped the genome of both Sasi Ardi and Latxa sheep. Our results suggest that Sasi Ardi traits related to energy metabolism, morphological, reproductive, and immunological features have been under positive selection to adapt this semi feral sheep to its particular environment. The highly selected Latxa sheep for dairy production showed clear signatures of selection in genomic regions related to milk production. Furthermore, our data indicate that the selection criteria applied in the modern genetic improvement program affect immunity and reproduction traits. PMID- 29566644 TI - The characteristics of ctDNA reveal the high complexity in matching the corresponding tumor tissues. AB - BACKGROUND: Next-generation sequencing (NGS) is an efficient and sensitive method to detect mutations from ctDNA. Many features and clinical conditions could significantly affect the concordance between ctDNA and corresponding tumor tissues. Our goal was to systematically investigate the critical factors contributing to different concordance between ctDNA and corresponding tumor tissues. METHODS: We recruited two groups of IIIB or IV lung cancer patients: The standard group to evaluate the accuracy of our method and the concordance between ctDNA and tumor tissues, and the study group with various clinical conditions. We applied our unique identification (UID) indexed capturing-based sequencing (UC Seq) to ctDNA samples, and confirm the results by Droplet digital PCR (ddPCR). RESULTS: Considering mutations detected from NGS of tumor tissues as golden standard, UC-Seq achieved overall 93.6% sensitivity for SNVs and Indels, and 0.8 Pearson correlation between tumor TMB and bTMB. Efficacious treatments, long sampling date (more than 2 weeks) between tumor tissues and ctDNA and low concentrations of cfDNA (less than 9 ng/ml) could significantly decrease the concordance between ctDNA and tumor tissues. About 84% mutations showed shorter mutant fragment length than that of wild-type fragments, and the AFs of mutations could be significantly enriched in small-size ctDNA. CONCLUSIONS: In late-stage lung cancer patients, ctDNA generally has high concordance with tumor tissues. However it could be significantly affected by three clinical conditions which could dynamically change the content of ctDNA. Moreover, the detection limit could be further extended by enriching small-size ctDNA in the preparation of samples. PMID- 29566645 TI - Oscillatory motor patterning is impaired in neurofibromatosis type 1: a behavioural, EEG and fMRI study. AB - BACKGROUND: Neurofibromatosis type1 (NF1) is associated with a broad range of behavioural deficits, and an imbalance between excitatory and inhibitory neurotransmission has been postulated in this disorder. Inhibition is involved in the control of frequency and stability of motor rhythms. Therefore, we aimed to explore the link between behavioural motor control, brain rhythms and brain activity, as assessed by EEG and fMRI in NF1. METHODS: We studied a cohort of 21 participants with NF1 and 20 age- and gender-matched healthy controls, with a finger-tapping task requiring pacing at distinct frequencies during EEG and fMRI scans. RESULTS: We found that task performance was significantly different between NF1 and controls, the latter showing higher tapping time precision. The time-frequency patterns at the beta sub-band (20-26 Hz) mirrored the behavioural modulations, with similar cyclic synchronization/desynchronization patterns for both groups. fMRI results showed a higher recruitment of the extrapyramidal motor system (putamen, cerebellum and red nucleus) in the control group during the fastest pacing condition. CONCLUSIONS: The present study demonstrated impaired precision in rhythmic pacing behaviour in NF1 as compared with controls. We found a decreased recruitment of the cerebellum, a structure where inhibitory interneurons are essential regulators of rhythmic synchronization, and in deep brain regions pivotally involved in motor pacing. Our findings shed light into the neural underpinnings of motor timing deficits in NF1. PMID- 29566646 TI - Early and late feathering in turkey and chicken: same gene but different mutations. AB - BACKGROUND: Sex-linked slow (SF) and fast (FF) feathering rates at hatch have been widely used in poultry breeding for autosexing at hatch. In chicken, the sex linked K (SF) and k+ (FF) alleles are responsible for the feathering rate phenotype. Allele K is dominant and a partial duplication of the prolactin receptor gene has been identified as the causal mutation. Interestingly, some domesticated turkey lines exhibit similar slow- and fast-feathering phenotypes, but the underlying genetic components and causal mutation have never been investigated. In this study, our aim was to investigate the molecular basis of feathering rate at hatch in domestic turkey. RESULTS: We performed a sequence based case-control association study and detected a genomic region on chromosome Z, which is statistically associated with rate of feathering at hatch in turkey. We identified a 5-bp frameshift deletion in the prolactin receptor (PRLR) gene that is responsible for slow feathering at hatch. All female cases (SF turkeys) were hemizygous for this deletion, while 188 controls (FF turkeys) were hemizygous or homozygous for the reference allele. This frameshift mutation introduces a premature stop codon and six novel amino acids (AA), which results in a truncated PRLR protein that lacks 98 C-terminal AA. CONCLUSIONS: We present the causal mutation for feathering rate in turkey that causes a partial C terminal loss of the prolactin receptor, and this truncated PRLR protein is strikingly similar to the protein encoded by the slow feathering K allele in chicken. PMID- 29566647 TI - Balanced selection on purebred and crossbred performance increases gain in crossbreds. AB - BACKGROUND: Genomic selection can be applied to select purebreds for crossbred performance (CP). The average performance of crossbreds can be considered as the summation of two components, i.e. the breed average (BA) of the parental breeds and heterosis (H) present in crossbreds. Selection of pure breeds for CP based on genomic estimated breeding values for crossbred performance (GEBV-C) or for purebred performance (GEBV-P) may differ in their ability to exploit BA and H and can affect the merit of crossbreds in both the short and long term. Selection based on GEBV-C is beneficial for CP, because H in crossbreds is efficiently exploited, whereas selection on GEBV-P results in more genetic progress in pure breeds, which increases the BA component of CP. To investigate the outcome of selection on GEBV-C and GEBV-P in both the short and long term, a two-way crossbreeding program was simulated to test the following hypotheses: (1) does selection on GEBV-P result in higher long-term CP compared to selection on GEBV-C and (2) does selection on a combination of GEBV-P and GEBV-C lead to more long term gain in CP than selection on either separately. METHODS: We investigated the performance of crossbreds in a two-way crossbreeding program across 40 generations and considered different criteria to select purebred parents that ranged from selection on purebred performance to selection for CP with different weights on genomic evaluations based on purebred and CP. These criteria were compared under three genetic models to investigate the effects of the amount of dominance variance, absence of over-dominance, and the structure of the reference population on CP, both in the short and long term. RESULTS AND CONCLUSIONS: Although beneficial in the short to medium term, genomic selection in pure breeds on a criterion that specifically targets CP was inferior to selection for purebred performance in the long term. A selection criterion that maximizes a combination of short- and long-term responses in CP, should improve the components that define crossbred merit (i.e., BA and H) simultaneously. PMID- 29566648 TI - Estimating the health consequences of flight attendant work: comparing flight attendant health to the general population in a cross-sectional study. AB - BACKGROUND: Flight attendants are an understudied occupational group, despite undergoing a wide and unique range of adverse job-related exposures. In our study, we aimed to characterize the health profile of cabin crew relative to the U.S. general population. METHODS: In 2014-2015, we surveyed participants of the Harvard Flight Attendant Health Study. We compared the prevalence of their health conditions to a contemporaneous cohort in the National Health and Nutrition Examination Survey (NHANES 2013-2014) using age-weighted standardized prevalence ratios (SPRs). We also analyzed associations between job tenure and selected health outcomes, using logistic regression and adjusting for potential confounders. RESULTS: Compared to the NHANES population (n = 2729), flight attendants (n = 5366) had a higher prevalence of female reproductive cancers (SPR = 1.66, 95% CI: 1.18-2.33), cancers at all sites (SPR = 2.15, 95% CI: 1.73-2.67 among females), as well as sleep disorders, fatigue, and depression, with SPRs ranging between 1.98 and 5.57 depending on gender and the specific condition examined. In contrast, we observed a decreased prevalence of cardiac and respiratory outcomes among flight crew relative to NHANES. Health conditions that increased with longer job tenure were sleep disorders, anxiety/depression, alcohol abuse, any cancer, peripheral artery disease, sinusitis, foot surgery, infertility, and several perinatal outcomes. CONCLUSIONS: We observed higher rates of specific adverse health outcomes in U.S. flight attendants compared to the general population, as well as associations between longer tenure and health conditions, which should be interpreted in light of recall bias and a cross sectional design. Future longitudinal studies should evaluate specific exposure disease associations among flight crew. PMID- 29566649 TI - Contextualising health screening risk assessments in police custody suites - qualitative evaluation from the HELP-PC study in London, UK. AB - BACKGROUND: In the UK, police custody officers have a responsibility to screen for health morbidity and vulnerability among detainees. This study aimed to develop an understanding of the barriers to performing effective health screening in police custody suites, understand the impact of screening tools on practice within the custody suite, and to identify factors that could hinder or facilitate the future implementation of a new screening intervention in this environment. METHODS: A qualitative study was conducted alongside a quantitative evaluation of a novel screening tool. Qualitative methods included observation of the custody environment, semi-structured interviews with police staff, and elicitation of comments from detainees about their experiences of screening. Data were analysed inductively using thematic analysis. Normalization Process Theory (NPT) was used to inform data collection and as a framework for higher level analysis of findings. RESULTS: Five overall constructs were identified that develop understanding of the integration of health screening within custody: the workability of risk assessment screening tools; the effect of the custody environment and the people therein; shifts in professional roles and interrelationships amongst staff; cultural responses to risk and liability in police work; how infrastructure, knowledge and skills can impact on detainee safety. CONCLUSIONS: Health and risk assessment screening in police custody is a complex and demanding activity which extends beyond the delivery of a screening tool. Professional roles, the demanding environment and police culture impact on the overall process. Recommendations for improved integration of health and risk assessment screening in wider police custody practice are proposed. PMID- 29566650 TI - Short-term changes of choroidal vascular structures after phacoemulsification surgery. AB - BACKGROUND: To evaluate the changes of choroidal vascular structures in patients after phacoemulsification surgery. METHODS: A self-control study was conducted on 36 eyes of 36 patients who had uneventful phacoemulsification. Choroidal images were acquired preoperatively, 7 days (D7), 1 month (M1), and 3 months (M3) after surgery from enhanced depth imaging (EDI) optical coherence tomography (OCT) scans. Choroidal vascularity index (CVI) was used to assess vascular status of the choroid using image binarization by the Niblack method. The postoperative values of mean CVI were compared with baseline by paired t-test. Univariate and multiple linear regression analyses were performed to determine the associations between CVI and other factors. RESULTS: The mean age of the recruited patients was 63.1 +/- 6.9 years. The mean CVI at baseline was 60.1 +/- 5.5%. After surgery, the CVI significantly increased to 61.7 +/- 5.3% at D7, 63.6 +/- 4.4% at M1 and 64.8 +/- 4.0% at M3 (p = 0.035, 0.0006, < 0.0001, respectively). Univariate and multiple regression analysis revealed a positive association between CVI and subfoveal choroidal thickness (SFCT) at pre-operation and no significant association with age, axial length (AL), intraocular pressure (IOP) and gender at all timepoints. CONCLUSIONS: Phacoemulsification induced increased CVI in patients diagnosed with cataract. Evaluation of the long-term change of CVI following surgery may provide valuable information for studying the relationship between phacoemulsification and disorders of the choroid. PMID- 29566651 TI - Complementary surveillance strategies are needed to better characterise the epidemiology, care pathways and treatment outcomes of tuberculosis in children. AB - BACKGROUND: Tuberculosis (TB) in young and HIV-infected children is frequently diagnosed at hospital level. In settings where general hospitals do not function as TB reporting units, the burden and severity of childhood TB may not be accurately reflected in routine TB surveillance data. Given the paucibacillary nature of childhood TB, microbiological surveillance alone will miss the majority of hospital-managed children. The study objective was to combine complementary hospital-based surveillance strategies to accurately report the burden, spectrum and outcomes of childhood TB managed at referral hospital-level in a high TB burden setting. METHODS: We conducted a prospective cohort study including all children (< 13 years) managed for TB at a large referral hospital in Cape Town, South Africa during 2012. Children were identified through newly implemented clinical surveillance in addition to existing laboratory surveillance. Data were collected from clinical patient records, the National Health Laboratory Service database, and provincial electronic TB registers. Descriptive statistics were used to report overall TB disease burden, spectrum, care pathways and treatment outcomes. Univariate analysis compared characteristics between children identified through the two hospital-based surveillance strategies to characterise the group of children missed by existing laboratory surveillance. RESULTS: During 2012, 395 children (180 [45.6%] < 2 years) were managed for TB. Clinical surveillance identified 237 (60%) children in addition to laboratory surveillance. Ninety (24.3%) children were HIV co-infected; 113 (29.5%) had weight-for-age z-scores <- 3. Extra-pulmonary TB (EPTB) was diagnosed in 188 (47.6%); 77 (19.5%) with disseminated TB. Favourable TB treatment outcomes were reported in 300/344 (87.2%) children with drug-susceptible and 50/51 (98.0%) children with drug-resistant TB. Older children (OR 1.7; 95% CI 1.0-2.8), children with EPTB (OR 2.3; 95% CI 1.5-3.6) and in-hospital deaths (OR 5.4; 95% CI 1.1-26.9) were more frequently detected by laboratory surveillance. TB/HIV co infected children were less likely to be identified through laboratory surveillance (OR 0.3; 95% CI 0.2-0.5). CONCLUSIONS: The burden and spectrum of childhood TB disease managed at referral hospital level in high burden settings is substantial. Hospital-based surveillance in addition to routine TB surveillance is essential to provide a complete picture of the burden, spectrum and impact of childhood TB in settings where hospitals are not TB reporting units. PMID- 29566652 TI - Yoga for posttraumatic stress disorder - a systematic review and meta-analysis. AB - BACKGROUND: Yoga is increasingly used as a therapeutic treatment and seems to improve psychiatric conditions such as anxiety disorders and depression. The aim of this systematic review was to assess the evidence of yoga for reducing symptoms of posttraumatic stress disorder (PTSD). METHODS: The Cochrane Library, Medline/PubMed, PsycINFO, Scopus, and IndMED were searched through July 2017 for randomized controlled trials (RCTs) assessing the effects of yoga on symptoms of PTSD. Mean differences (MD) and standardized mean differences (SMD) with 95% confidence intervals (CI) were computed. The quality of evidence and the strength of recommendation were graded according to the GRADE recommendations. RESULTS: Seven RCTs (N = 284) were included. Meta-analysis revealed low quality evidence for clinically relevant effects of yoga on PTSD symptoms compared to no treatment (SMD = - 1.10, 95% CI [- 1.72, - 0.47], p < .001, I2 = 72%; MD = - 13.11, 95% CI [- 17.95, - 8.27]); and very low evidence for comparable effects of yoga and attention control interventions (SMD = - 0.31, 95%CI = [- 0.84, 0.22], p = .25; I2 = 43%). Very low evidence was found for comparable retention of patients in the trial for yoga and no treatment (OR = 0.68, 95%CI [0.06, 7.72]) or attention control interventions (OR = 0.66, 95%CI [0.10, 4.46]). No serious adverse events were reported. LIMITATIONS: Few RCTs with only limited sample size were available. CONCLUSIONS: Only a weak recommendation for yoga as an adjunctive intervention for PTSD can be made. More high quality research is needed to confirm or disconfirm these findings. PMID- 29566654 TI - A quantitative analysis method for comitant exotropia using video-oculography with alternate cover. AB - BACKGROUND: The purpose of this study was to evaluate the efficacy of a quantitative analysis method for comitant exotropia using video-oculography (VOG) with alternate cover. METHODS: Thirty-four subjects with comitant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using the alternate prism cover test (APCT). The video files and data of changes in ocular deviation during the alternate cover test were obtained using VOG. To verify the accuracy of VOG, the value obtained using VOG and the angle of a rotating model eye were compared, and a new linear equation was subsequently derived using these data. The calculated values obtained using VOG were compared with those obtained using the APCT. RESULTS: Rotation of the model eye and the values obtained using VOG demonstrated excellent positive correlation (R = 1.000; p < 0.001). A simple linear regression model was obtained: rotation of the model eye = 0.978 * value obtained using VOG for a model eye - 0.549. The 95% limit of agreement for inter-observer variability was +/-4.63 prism diopters (PD) for APCT and that for test-retest variability was +/-3.56 PD for the VOG test. The results of APCT and calculated VOG test demonstrated a strong positive correlation. Bland Altman plots revealed no overall tendency for the calculated values obtained from VOG to differ from those obtained using APCT. CONCLUSIONS: VOG with alternate cover is a non-invasive and accurate tool for quantitatively measuring and recording ocular deviation. In particular, it is independent of the proficiency of the examiner and, can therefore, be useful in the absence of skilled personnel.

PMID- 29566653 TI - Transcriptomic analysis reveals overdominance playing a critical role in nicotine heterosis in Nicotiana tabacum L. AB - BACKGROUND: As a unique biological phenomenon, heterosis has been concerned with the superior performance of the heterosis than either parents. Despite several F1 hybrids, containing supernal nicotine content, had been discovered and applied to heterosis utilization in Nicotiana tabacum L., nevertheless, the potential molecular mechanism revealing nicotine heterosis has not been illustrated clearly. RESULT: Phenotypically, the F1 hybrids (Vall6 * Basma) show prominent heterosis in nicotine content by 3 years of field experiments. Transcriptome analysis revealed that genes participating in nicotine anabolism (ADC, PMT, MPO, QPT, AO, QS, QPT, A622, BBLs) and nicotine transport (JAT2, MATE1 and 2, NUP1 and 2) showed an upregulated expression in the hybrid, a majority of which demonstrated an overdominant performance. RT-PCR confirmed that nicotine anabolism was induced in the hybrid. CONCLUSIONS: These findings strongly suggest that nicotine synthesis and transport efficiency improved in hybrid and overdominance at gene-expression level played a critical role in heterosis of nicotine metabolism. PMID- 29566655 TI - Maternal death and delays in accessing emergency obstetric care in Mozambique. AB - BACKGROUND: Despite declining trends maternal mortality remains an important public health issue in Mozambique. The delays to reach an appropriate health facility and receive care faced by woman with pregnancy related complications play an important role in the occurrence of these deaths. This study aims to examine the contribution of the delays in relation to the causes of maternal death in facilities in Mozambique. METHODS: Secondary analysis was performed on data from a national assessment on maternal and neonatal health that included in depth maternal death reviews, using patient files and facility records with the most comprehensive information available. Statistical models were used to assess the association between delay to reach the health facility that provides emergency obstetric care (delay type II) and delay in receiving appropriate care once reaching the health facility providing emergency obstetric care (delay type III) and the cause of maternal death within the health facility. RESULTS: Data were available for 712 of 2,198 maternal deaths. Delay type II was observed in 40.4% of maternal deaths and delay type III in 14.2%.and 13.9% had both delays. Women who died of a direct obstetric complication were more likely to have experienced a delay type III than women who died due to indirect causes. Women who experienced delay type II were less likely to have also delay type III and vice versa. CONCLUSIONS: The delays in reaching and receiving appropriate facility-based care for women facing pregnancy related complications in Mozambique contribute significantly to maternal mortality. Securing referral linkages and health facility readiness for rapid and correct patient management are needed to reduce the impact of these delays within the health system. PMID- 29566656 TI - Efficacy and cost-effectiveness of a blended cognitive behavioral therapy for depression in Spanish primary health care: study protocol for a randomised non inferiority trial. AB - BACKGROUND: Data from primary health care in Spain show a high prevalence of the major depressive disorder. Blended treatment (combination of face-to-face and online components) seems to be a very promising tool for the optimization and dissemination of psychological treatments in a cost-effective form. Although there is growing data that confirm the advantages of blended therapies, few studies have analyzed their application in regular clinical practice. The objective of the present paper is to describe the protocol for a clinical study aimed at exploring the clinical and cost-effectiveness of a blended cognitive behavioral therapy (b-CBT) for depression, compared to treatment as usual (TAU) in a primary health care setting. METHODS: A two-arm randomised controlled non inferiority trial will be carried out, with repeated measures (baseline, 3 months, 6 months, and 12 months) under two conditions: b-CBT and TAU. The b-CBT program will consist in three face-to-face sessions and eight online sessions. The TAU is defined as the routine care delivered by the general practitioner for the treatment of depression in primary care. The primary outcome is a symptomatic change of depressive symptoms on the patient-health questionnaire (PHQ-9). Other secondary outcomes will be considered (e.g., quality of life, treatment preference). All participants must be 18 years of age or older and meet the diagnostic criteria for major depressive disorder according to the Diagnostic and Statistical Manual of Mental disorders 4th edition. 156 participants will be recruited (78 per arm). DISCUSSION: It is expected that b-CBT is clinically non inferior when compared to TAU. This is the first study in Spain to use a b-CBT format in primary and specialized care, and this format could be an efficacious and cost-effective therapeutic strategy for the treatment of depression.

PMID- 29566657 TI - Germline breast cancer susceptibility gene mutations and breast cancer outcomes. AB - BACKGROUND: It is unclear whether germline breast cancer susceptibility gene mutations affect breast cancer related outcomes. We wanted to evaluate mutation patterns in 20 breast cancer susceptibility genes and correlate the mutations with clinical characteristics to determine the effects of these germline mutations on breast cancer prognosis. METHODS: The study cohort included 480 ethnic Chinese individuals in Taiwan with at least one of the six clinical risk factors for hereditary breast cancer: family history of breast or ovarian cancer, young age of onset for breast cancer, bilateral breast cancer, triple negative breast cancer, both breast and ovarian cancer, and male breast cancer. PCR enriched amplicon-sequencing on a next generation sequencing platform was used to determine the germline DNA sequences of all exons and exon-flanking regions of the 20 genes. Protein-truncating variants were identified as pathogenic. RESULTS: We detected a 13.5% carrier rate of pathogenic germline mutations, with BRCA2 being the most prevalent and the non-BRCA genes accounting for 38.5% of the mutation carriers. BRCA mutation carriers were more likely to be diagnosed of breast cancer with lymph node involvement (66.7% vs 42.6%; P = 0.011), and had significantly worse breast cancer specific outcomes. The 5-year disease-free survival was 73.3% for BRCA mutation carriers and 91.1% for non-carriers (hazard ratio for recurrence or death 2.42, 95% CI 1.29-4.53; P = 0.013). After adjusting for clinical prognostic factors, BRCA mutation remained an independent poor prognostic factor for cancer recurrence or death (adjusted hazard ratio 3.04, 95% CI 1.40-6.58; P = 0.005). Non-BRCA gene mutation carriers did not exhibit any significant difference in cancer characteristics or outcomes compared to those without detected mutations. Among the risk factors for hereditary breast cancer, the odds of detecting a germline mutation increased significantly with having bilateral breast cancer (adjusted odds ratio 3.27, 95% CI 1.64-6.51; P = 0.0008) or having more than one risk factor (odds ratio 2.07, 95% CI 1.22-3.51; P = 0.007). CONCLUSIONS: Without prior knowledge of the mutation status, BRCA mutation carriers had more advanced breast cancer on initial diagnosis and worse cancer-related outcomes. Optimal approach to breast cancer treatment for BRCA mutation carriers warrants further investigation. PMID- 29566658 TI - Punch biopsies shorten time to clearance of high-risk human papillomavirus infections of the uterine cervix. AB - BACKGROUND: The primary objective was to determine human papilloma virus (HPV) clearance rate after cervical biopsy among women with persistent high-risk HPV infection compared with spontaneous HPV clearance rate in the absence of biopsy. METHODS: We collected data from a dedicated screening program of women aged 30-70 years old. Inclusion criteria for the baseline non-interventional cohort were a positive HPV test (hybrid capture 2, HC2) and normal cytology. In the baseline cohort women were followed with approximately yearly HPV-tests and cytology until HPV regressed (one negative HPV test) or interventions in the form of diagnostic biopsies or therapy. Women who had a diagnostic biopsy were included in the biopsy cohort and followed until HPV regression or therapy. Observed HPV regression rates and time to HPV regression were compared between baseline and biopsy cohorts. For the comparison, we used Fisher's exact test for the HPV regression rates and interval-censored, accelerated failure time model for time to HPV regression. RESULTS: Among the 1079 women included in the baseline cohort, 499 (46.3%) had HPV clearance and 475 were referred for colposcopy with biopsy. The biopsy cohort comprised all women who were not treated and had at least one HC2 test after biopsy (201/475; 42.3%). Of those, 138 (68.7%) experienced HPV regression. In the biopsy cohort, time to clearance of HPV infection was approximately halved (0.46, 95% CI 0.38-0.56) compared with the baseline cohort. This result was robust in a wide range of sensitivity analyses. CONCLUSIONS: A higher proportion of women cleared their HPV infection, and time to HPV clearance was shorter in the biopsy cohort than in the baseline cohort. It is reassuring for clinicians to know that conservative management of patients with HPV persistency is successful when colposcopy with biopsies excludes high-grade disease. PMID- 29566659 TI - Accelerating newborn survival in Ghana through a low-dose, high-frequency health worker training approach: a cluster randomized trial. AB - BACKGROUND: Newborn deaths comprise nearly half of under-5 deaths in Ghana, despite the fact that skilled birth attendants (SBAs) are present at 68% of births, which implies that evidence-based care during labor, birth and the immediate postnatal period may be deficient. We assessed the effect of a low dose, high-frequency (LDHF) training approach on long-term evidence-based skill retention among SBAs and impact on adverse birth outcomes. METHODS: From 2014 to 2017, we conducted a cluster-randomized trial in 40 hospitals in Ghana. Eligible hospitals were stratified by region and randomly assigned to one of four implementation waves. We assessed the relative risks (RRs) of institutional intrapartum stillbirths and 24-h newborn mortality in months 1-6 and 7-12 of implementation as compared to the historical control period, and in post intervention facilities compared to pre-intervention facilities during the same period. All SBAs providing labor and delivery care were invited to enroll; their knowledge and skills were assessed pre- and post-training, and 1 year later. RESULTS: Adjusting for region and health facility type, the RR of 24-h newborn mortality in the 40 enrolled hospitals was 0.41 (95% CI 0.32-0.51; p < 0.001) in months 1-6 and 0.30 (95% CI 0.21-0.43; p < 0.001) in months 7-12 compared to baseline. The adjusted RR of intrapartum stillbirth was 0.64 (95% CI 0.53-0.77; p < 0.001) in months 1-6 and 0.48 (95% CI 0.36-0.63; p < 0.001) in months 7-12 compared to baseline. Four hundred three SBAs consented and enrolled. After 1 year, 200 SBAs assessed had 28% (95% CI 25-32; p < 0.001) and 31% (95% CI 27-36; p < 0.001) higher scores than baseline on low-dose 1 and 2 content skills, respectively. CONCLUSIONS: This training approach results in a sustained decrease in facility-based newborn mortality and intrapartum stillbirths, and retained knowledge and skills among SBAs after a year. We recommend use of this approach for future maternal and newborn health in-service training and programs. TRIAL REGISTRATION: Retrospectively registered on 25 September 2017 at Clinical Trials, identifier NCT03290924 . PMID- 29566660 TI - Mutations of rpoB, katG, inhA and ahp genes in rifampicin and isoniazid-resistant Mycobacterium tuberculosis in Kyrgyz Republic. AB - BACKGROUND: The aim of this study was to identify mutations of rpoB, katG, inhA and ahp-genes associated Mycobacterium tuberculosis resistance to rifampicin (RIF) and isoniazid (INH) in Kyrgyz Republic. We studied 633 smear samples from the primary pulmonary tuberculosis (TB) patients. We verified Mycobacterium tuberculosis susceptibility to RIF and INH using culture method of absolute concentrations, and commercially available test named "TB-BIOCHIP" (Biochip-IMB, Moscow, Russian Federation). RESULTS: For RIF-resistance, TB-BIOCHIP's sensitivity and specificity were 88% and 97%, 84% and 95% for INH-resistance, and 90% and 97% for multi-drug resistance (MDR). In RIF-resistant strains, TB-BIOCHIP showed mutations in codons 531 (64.8%), 526 (17.3%), 516 (8.1%), 511 (5.4%), 533 (3.2%), 522 (0.6%) and 513 (0.6%) of rpoB gene. The most prevalent was Ser531 > Leu mutation (63.7%). 91.2% of mutations entailing resistance to INH were in katG gene, 7% in inhA gene, and 1.8% in ahpC gene. Ser315->Thr (88.6%) was the most prevalent mutation leading to resistance to INH. CONCLUSIONS: In Kyrgyz Republic, the most prevalent mutation in RIF-resistant strains was Ser531 -> Leu in rpoB gene, as opposed to Ser315 -> Thr in katG gene in INH-resistant Mycobacterium tuberculosis. In Kyrgyz Republic, the major reservoir of MDR Mycobacterium tuberculosis were strains with combined mutations Ser531 -> Leu in rpoB gene and Ser315 -> Thr in katG gene. TB-BIOCHIP has shown moderate sensitivity with the advantage of obtaining results in only two days. PMID- 29566661 TI - Blocking hexose entry into glycolysis activates alternative metabolic conversion of these sugars and upregulates pentose metabolism in Aspergillus nidulans. AB - BACKGROUND: Plant biomass is the most abundant carbon source for many fungal species. In the biobased industry fungi, are used to produce lignocellulolytic enzymes to degrade agricultural waste biomass. Here we evaluated if it would be possible to create an Aspergillus nidulans strain that releases, but does not metabolize hexoses from plant biomass. For this purpose, metabolic mutants were generated that were impaired in glycolysis, by using hexokinase (hxkA) and glucokinase (glkA) negative strains. To prevent repression of enzyme production due to the hexose accumulation, strains were generated that combined these mutations with a deletion in creA, the repressor involved in regulating preferential use of different carbon catabolic pathways. RESULTS: Phenotypic analysis revealed reduced growth for the hxkA1 glkA4 mutant on wheat bran. However, hexoses did not accumulate during growth of the mutants on wheat bran, suggesting that glucose metabolism is re-routed towards alternative carbon catabolic pathways. The creADelta4 mutation in combination with preventing initial phosphorylation in glycolysis resulted in better growth than the hxkA/glkA mutant and an increased expression of pentose catabolic and pentose phosphate pathway genes. This indicates that the reduced ability to use hexoses as carbon sources created a shift towards the pentose fraction of wheat bran as a major carbon source to support growth. CONCLUSION: Blocking the direct entry of hexoses to glycolysis activates alternative metabolic conversion of these sugars in A. nidulans during growth on plant biomass, but also upregulates conversion of other sugars, such as pentoses. PMID- 29566662 TI - Age greater than 60 years portends a worse prognosis in patients with papillary thyroid cancer: should there be three age categories for staging? AB - BACKGROUND: Age is an important prognostic factor in papillary thyroid cancer (PTC), with better survival observed in patients < 45 years of age, regardless of stage. Although the impact of increasing age on PTC-related survival is well known, previous studies have focused on survival relative to age 45 years only. As the number of patients entering their 7th decade of life increases, PTC related survival in this demographic becomes increasingly important. Survival in patients >= 60 years specifically compared to other groups has not previously been examined. We sought to determine whether age >= 60 years is an adverse prognostic factor for disease-specific survival and recurrence in patients with PTC. METHODS: The California Cancer Registry database was linked to inpatient and ambulatory patient records from the Office of Statewide Health Planning and Development for the years 2000-2011. This linked database was queried for patients diagnosed with papillary thyroid cancer and treated with surgery. We then identified prognostic factors related to both 5-year and 10-year disease specific survival and disease-free survival in patients <= 45, 45-59, and >= 60 years. Multivariable Cox proportional hazard models were created to test the effect of age >= 60 on disease-specific and disease-free survival, controlling for clinical, treatment, and demographic factors. RESULTS: The final cohort included 15,675 patients. Of the group, 46.3% were between 18 and 44 years of age, 33.6% were 45-59 years, and 20.1% were >= 60. Univariate analysis showed that compared to other groups, patients >= 60 were more likely to be male (p < 0.001), present with tumors > 5 cm (p < 0.001), more likely to have metastatic disease (p < 0.001), less likely to receive radioactive iodine (p < 0.001), and more likely to receive external beam radiation therapy (p < 0.001). In multivariable Cox proportional hazards models for 5 and 10-year disease-free survival, age >= 60 was associated with higher risk of disease at 5 and 10-years (HR 2.3 and 1.9 respectively, p < 0.001). Similar results were observed for 5 and 10-year disease-specific survival (HR 38.0 and 30.0 respectively, p < 0.001) after controlling for gender, race, co-morbidity, stage, surgical procedure, radioactive iodine, insurance, and hospital volume. CONCLUSIONS: Patients >= 60 years of age have worse DSS and DFS after a diagnosis of PTC, across all stages of disease. Given that patients over the age of 45 years have progressively worse survival as they age, these data support having three age groups, 18-44 years of age, 45-59 years, and >= 60 as an independent predictor of survival and recurrence to current staging guidelines. PMID- 29566663 TI - Unconditional and conditional QTL analyses of seed fatty acid composition in Brassica napus L. AB - BACKGROUND: The fatty acid composition of B. napus' seeds determines the oil's nutritional and industrial values, and affects seed germination. Many studies have reported correlations among C16:0, C18:0, C18:1, C18:2 and C18:3 based on phenotypic data; however, the genetic basis of the fatty acid composition in B. napus is still not well understood. RESULTS: In this study, unconditional and conditional quantitative trail locus (QTL) mapping analyses were conducted using a recombinant inbred line in six environments. In total, 21 consensus QTLs each for C16:0, C18:0 and C18:2, 16 for C18:1 and 22 for C18:3 were detected by unconditional mapping. The QTLs with overlapping confidence intervals were integrated into 71 pleiotropically unique QTLs by meta-analysis. Two major QTLs, uuqA5-6 and uuqA5-7, simultaneously affected the fatty acids, except C18:0, in most of environments, with the homologous genes fatty acid desaturase 2 (FAD2) and glycerol-3-phosphate sn-2-acyltransferase 5 (GPAT5) occurring in the confidence interval of uuqA5-6, while phosphatidic acid phosphohydrolase 1 (PAH1) was assigned to uuqA5-7. Moreover, 49, 30, 48, 60 and 45 consensus QTLs were detected for C16:0, C18:0, C18:1, C18:2 and C18:3, respectively, by the conditional mapping analysis. In total, 128 unique QTLs were subsequently integrated from the 232 conditional consensus QTLs. A comparative analysis revealed that 63 unique QTLs could be identified by both mapping methodologies, and 65 additional unique QTLs were only identified in conditional mapping. CONCLUSIONS: Thus, conditional QTL mapping for fatty acids may uncover numerous additional QTLs that were inhibited by the effects of other traits. These findings provide useful information for better understanding the genetic relationships among fatty acids at the QTL level. PMID- 29566664 TI - Rival seminal fluid induces enhanced sperm motility in a polyandrous ant. AB - BACKGROUND: Promiscuous mating and sperm competition often induce arms races between the sexes with detrimental outcomes for females. However, ants with multiply-inseminated queens have only a single time-window for sperm competition and queens are predicted to gain control over the outcome of sperm storage quickly. The seminal fluid of Acromyrmex leaf-cutting ants reduces the viability of rival sperm, but how confrontations between unrelated ejaculates affect sperm storage remains unknown. RESULTS: We investigated the effects of ejaculate admixture on sperm motility in A. echinatior and found that the proportion of motile spermatozoa, sperm swimming speed, and linearity of sperm movement increased when rival ejaculates were mixed in vitro. Major effects induced by the seminal fluid of rival males were of similar magnitude to those generated by queen reproductive tract secretions, whereas own seminal fluid induced lower sperm activation levels. CONCLUSIONS: Our results suggest that ant sperm respond via a self-non-self recognition mechanism to similar or shared molecules expressed in the reproductive secretions of both sexes. Lower sperm motility in the presence of own seminal fluid indicates that enhanced motility is costly and may trade-off with sperm viability during sperm storage, consistent with studies in vertebrates. Our results imply that ant spermatozoa have evolved to adjust their energetic expenditure during insemination depending on the perceived level of sperm competition. PMID- 29566665 TI - Development of a measurement approach to assess time children participate in organized sport, active travel, outdoor active play, and curriculum-based physical activity. AB - BACKGROUND: Children participate in four main types of physical activity: organized sport, active travel, outdoor active play, and curriculum-based physical activity. The objective of this study was to develop a valid approach that can be used to concurrently measure time spent in each of these types of physical activity. METHODS: Two samples (sample 1: n = 50; sample 2: n = 83) of children aged 10-13 wore an accelerometer and a GPS watch continuously over 7 days. They also completed a log where they recorded the start and end times of organized sport sessions. Sample 1 also completed an outdoor time log where they recorded the times they went outdoors and a description of the outdoor activity. Sample 2 also completed a curriculum log where they recorded times they participated in physical activity (e.g., physical education) during class time. RESULTS: We describe the development of a measurement approach that can be used to concurrently assess the time children spend participating in specific types of physical activity. The approach uses a combination of data from accelerometers, GPS, and activity logs and relies on merging and then processing these data using several manual (e.g., data checks and cleaning) and automated (e.g., algorithms) procedures. In the new measurement approach time spent in organized sport is estimated using the activity log. Time spent in active travel is estimated using an existing algorithm that uses GPS data. Time spent in outdoor active play is estimated using an algorithm (with a sensitivity and specificity of 85%) that was developed using data collected in sample 1 and which uses all of the data sources. Time spent in curriculum-based physical activity is estimated using an algorithm (with a sensitivity of 78% and specificity of 92%) that was developed using data collected in sample 2 and which uses accelerometer data collected during class time. There was evidence of excellent intra- and inter-rater reliability of the estimates for all of these types of physical activity when the manual steps were duplicated. CONCLUSIONS: This novel measurement approach can be used to estimate the time that children participate in different types of physical activity. PMID- 29566666 TI - Assessing linkage to and retention in care among HIV patients in Uganda and identifying opportunities for health systems strengthening: a descriptive study. AB - BACKGROUND: While antiretroviral therapy (ART) availability for HIV patients has increased dramatically in Uganda, patient linkage to and retention in care remains a challenge. We assessed patterns of engagement in care in 20 Ugandan health facilities with low retention based on national reporting. METHODS: We assessed patient linkage to care (defined as registering for pre-ART or ART care at the facility within 1 month of HIV diagnosis) and 6-month retention in care (having a visit 3-6 months after ART initiation) and associations with patient /facility-level factors using multivariate logistic regression. RESULTS: Among 928 newly HIV-diagnosed patients, only 53.0% linked to care within 1 month. Of these, 83.7% linked within 1 week. Among 678 newly initiated ART patients, 14.5% never returned for a follow-up visit at the facility. Retention was 71.7% according to our primary definition but much lower if stricter definitions were used. Most patients were already falling behind appointment schedules at their first ART follow-up (median: 28 days post-initiation vs. recommended 14 days). 27.3% of newly-initiated patients had follow-up appointments scheduled 45+ days apart rather than monthly per national guidelines. Linkage and retention were not strongly correlated with each other within facilities (rs = 0.06; p = 0.82). Females, adolescents, and patients in rural settings tended to have lower linkage and retention in multivariable-adjusted models. CONCLUSIONS: Linkage support may be most critical immediately after testing positive, as patients are less likely to link over time. More information is needed on reasons for appointment schedules by clinicians and implications on retention. TRIAL REGISTRATION: This study was registered in the Pan African Clinical Trial Registry database (#PACTR201611001756166). PMID- 29566667 TI - Work-related adverse events leaving their mark: a cross-sectional study among Dutch gynecologists. AB - BACKGROUND: Health care professionals who are frequently coping with traumatic events have an increased risk of developing a posttraumatic stress disorder. Research among physicians is scarce, and obstetrician-gynecologists may have a higher risk. Work-related traumatic events and posttraumatic stress disorder among obstetricians-gynecologists and the (desired) type of support were studied. METHODS: A questionnaire was emailed to all members of the Dutch Society of Obstetrics and Gynaecology, which included residents, attending, retired and non practicing obstetricians-gynecologists. The questionnaire included questions about personal experiences and opinions concerning support after work-related events, and a validated questionnaire for posttraumatic stress disorder. RESULTS: The response rate was 42.8% with 683 questionnaires eligible for analysis. 12.6% of the respondents have experienced a work-related traumatic event, of which 11.8% met the criteria for current posttraumatic stress disorder. This revealed an estimated prevalence of 1.5% obstetricians-gynecologists with current posttraumatic stress disorder. 12% reported to have a support protocol or strategy in their hospital after adverse events. The most common strategies to cope with emotional events were: to seek support from colleagues, to seek support from family or friends, to discuss the case in a complication meeting or audit and to find distraction. 82% would prefer peer-support with direct colleagues after an adverse event. CONCLUSIONS: This survey implies that work-related events can be traumatic and subsequently can lead to posttraumatic stress disorder. There is a high prevalence rate of current posttraumatic stress disorder among obstetricians-gynecologists. Often there is no standardized support after adverse events. Most obstetrician-gynecologists prefer peer-support with direct colleagues after an adverse event. More awareness must be created during medical training and organized support must be implemented. PMID- 29566668 TI - Oral medicine acceptance in infants and toddlers: measurement properties of the caregiver-administered Children's acceptance tool (CareCAT). AB - BACKGROUND: Developing age-appropriate medications remains a challenge in particular for the population of infants and toddlers, as they are not able to reliably self-report if they would accept and consequently take an oral medicine. Therefore, it is common to use caregivers as proxies when assessing medicine acceptance. The outcome measures used in this research field differ and most importantly lack validation, implying a persisting gap in knowledge and controversy in the field. The newly developed Caregiver-administered Children's Acceptance Tool (CareCAT) is based on a 5-point nominal scale, with descriptors of medication acceptance behavior. This cross-sectional study assessed the measurement properties of the tool with regards to the user's understanding and its intra- and inter-rater reliability. METHODS: Participating caregivers were enrolled at a primary healthcare facility where their children (median age 6 months) had been prescribed oral antibiotics. Caregivers, trained observers and the tool developer observed and scored on the CareCAT tool what behavior children exhibited when receiving the medicine (n = 104). The video-records of this process served as replicate observations (n = 69). After using the tool caregivers were asked to explain their observations and the tool descriptors in their own words. The tool's reliability was assessed by percentage agreement and Cohen's unweighted kappa coefficients of agreement for nominal scales. RESULTS: The study found that caregivers using CareCAT had a satisfactory understanding of the tool's descriptors. Using its dichotomized scores the tool reliably was strong for acceptance behavior (agreement inter-rater 84-88%, kappa 0.66-0.76; intra-rater 87-89%, kappa 0.68-0.72) and completeness of medicine ingestion (agreement inter-rater 82-86%, kappa 0.59-0.67; intra-rater 85-93%, kappa 0.50 0.70). CONCLUSIONS: The CareCAT is a low-cost, easy-to-use and reliable instrument, which is relevant to assess acceptance behavior and completeness of medicine ingestion, both of which are of significant importance for developing age-appropriate medications in infants and toddlers. PMID- 29566669 TI - RNA sequencing of early round goby embryos reveals that maternal experiences can shape the maternal RNA contribution in a wild vertebrate. AB - BACKGROUND: It has been proposed that non-genetic inheritance could promote species fitness. Non-genetic inheritance could allow offspring to benefit from the experience of their parents, and could advocate pre-adaptation to prevailing and potentially selective conditions. Indeed, adaptive parental effects have been modeled and observed, but the molecular mechanisms behind them are far from understood. RESULTS: In the present study, we investigated whether maternal RNA can carry information about environmental conditions experienced by the mother in a wild vertebrate. Maternal RNA directs the development of the early embryo in many non-mammalian vertebrates and invertebrates. However, it is not known whether vertebrate maternal RNA integrates information about the parental environment. We sequenced the maternal RNA contribution from a model that we expected to rely on parental effects: the invasive benthic fish species Neogobius melanostomus (Round Goby). We found that maternal RNA expression levels correlated with the water temperature experienced by the mother before oviposition, and identified temperature-responsive gene groups such as core nucleosome components or the microtubule cytoskeleton. CONCLUSIONS: Our findings suggest that the maternal RNA contribution may incorporate environmental information. Maternal RNA should therefore be considered a potentially relevant pathway for non-genetic inheritance. Also, the ability of a species to integrate environmental information in the maternal RNA contribution could potentially contribute to species fitness and may also play a role in extraordinary adaptive success stories of invasive species such as the round goby. PMID- 29566670 TI - The DNA methylation profile of liver tumors in C3H mice and identification of differentially methylated regions involved in the regulation of tumorigenic genes. AB - BACKGROUND: C3H mice have been frequently used in cancer studies as animal models of spontaneous liver tumors and chemically induced hepatocellular carcinoma (HCC). Epigenetic modifications, including DNA methylation, are among pivotal control mechanisms of gene expression leading to carcinogenesis. Although information on somatic mutations in liver tumors of C3H mice is available, epigenetic aspects are yet to be clarified. METHODS: We performed next generation sequencing-based analysis of DNA methylation and microarray analysis of gene expression to explore genes regulated by DNA methylation in spontaneous liver tumors of C3H mice. Overlaying these data, we selected cancer-related genes whose expressions are inversely correlated with DNA methylation levels in the associated differentially methylated regions (DMRs) located around transcription start sites (TSSs) (promoter DMRs). We further assessed mutuality of the selected genes for expression and DNA methylation in human HCC using the Cancer Genome Atlas (TCGA) database. RESULTS: We obtained data on genome-wide DNA methylation profiles in the normal and tumor livers of C3H mice. We identified promoter DMRs of genes which are reported to be related to cancer and whose expressions are inversely correlated with the DNA methylation, including Mst1r, Slpi and Extl1. The association between DNA methylation and gene expression was confirmed using a DNA methylation inhibitor 5-aza-2'-deoxycytidine (5-aza-dC) in Hepa1c1c7 cells and Hepa1-6 cells. Overexpression of Mst1r in Hepa1c1c7 cells illuminated a novel downstream pathway via IL-33 upregulation. Database search indicated that gene expressions of Mst1r and Slpi are upregulated and the TSS upstream regions are hypomethylated also in human HCC. These results suggest that DMRs, including those of Mst1r and Slpi, are involved in liver tumorigenesis in C3H mice, and also possibly in human HCC. CONCLUSIONS: Our study clarified genome wide DNA methylation landscape of C3H mice. The data provide useful information for further epigenetic studies of mice models of HCC. The present study particularly proposed novel DNA methylation-regulated pathways for Mst1r and Slpi, which may be applied not only to mouse HCC but also to human HCC. PMID- 29566671 TI - Completing sparse and disconnected protein-protein network by deep learning. AB - BACKGROUND: Protein-protein interaction (PPI) prediction remains a central task in systems biology to achieve a better and holistic understanding of cellular and intracellular processes. Recently, an increasing number of computational methods have shifted from pair-wise prediction to network level prediction. Many of the existing network level methods predict PPIs under the assumption that the training network should be connected. However, this assumption greatly affects the prediction power and limits the application area because the current golden standard PPI networks are usually very sparse and disconnected. Therefore, how to effectively predict PPIs based on a training network that is sparse and disconnected remains a challenge. RESULTS: In this work, we developed a novel PPI prediction method based on deep learning neural network and regularized Laplacian kernel. We use a neural network with an autoencoder-like architecture to implicitly simulate the evolutionary processes of a PPI network. Neurons of the output layer correspond to proteins and are labeled with values (1 for interaction and 0 for otherwise) from the adjacency matrix of a sparse disconnected training PPI network. Unlike autoencoder, neurons at the input layer are given all zero input, reflecting an assumption of no a priori knowledge about PPIs, and hidden layers of smaller sizes mimic ancient interactome at different times during evolution. After the training step, an evolved PPI network whose rows are outputs of the neural network can be obtained. We then predict PPIs by applying the regularized Laplacian kernel to the transition matrix that is built upon the evolved PPI network. The results from cross-validation experiments show that the PPI prediction accuracies for yeast data and human data measured as AUC are increased by up to 8.4 and 14.9% respectively, as compared to the baseline. Moreover, the evolved PPI network can also help us leverage complementary information from the disconnected training network and multiple heterogeneous data sources. Tested by the yeast data with six heterogeneous feature kernels, the results show our method can further improve the prediction performance by up to 2%, which is very close to an upper bound that is obtained by an Approximate Bayesian Computation based sampling method. CONCLUSIONS: The proposed evolution deep neural network, coupled with regularized Laplacian kernel, is an effective tool in completing sparse and disconnected PPI networks and in facilitating integration of heterogeneous data sources. PMID- 29566672 TI - Characteristics of exercise capacity in female systemic lupus erythematosus associated pulmonary arterial hypertension patients. AB - BACKGROUND: To study the oxygen uptake efficiency and determine usefulness of submaximal parameters of oxygen uptake in systemic lupus erythematosus associated pulmonary arterial hypertension (SLE PAH) on performing a cardiopulmonary exercise test (CPET). METHODS: CPET was performed in 21 SLE PAH patients, equal number of idiopathic pulmonary arterial hypertension (IPAH) patients and controls. Peak VO2, anaerobic threshold (AT), oxygen uptake efficiency slope (OUES) and oxygen uptake efficiency plateau (OUEP) and other CPET parameters were examined. All subjects had pulmonary function test (PFT) at rest, which included FEV1, FVC, FEV1/FVC, DLCO measurements. Right heart catheterization (RHC) was also done in SLE PAH and IPAH patients. CPET parameters were compared with RHC parameters to determine potential correlations. RESULTS: Peak VO2, PETCO2 and peak O2 pulse were lower in SLE PAH than IPAH and controls with OUE being lower during all stages of exercise in SLE PAH. DLCO and FVC values were significantly lower in SLE PAH (p < 0.05). Peak O2 pulse and VO2@AT in SLE PAH and IPAH was low (p < 0.05) and significant difference between SLE PAH and IPAH was seen (p < 0.05). PVR correlated with the lowest VE/VCO2, O2 pulse, peak PETCO2 and OUE in SLE PAH patients (all p < 0.05). CONCLUSIONS: SLE PAH patients have cardiopulmonary exercise limitation with reduced oxygen uptake efficiency. VO2@ at AT, peak O2 pulse and O2 pulse at AT were significantly reduced (p < 0.05). Key CPET parameters correlated with elevated pulmonary vascular resistance (PVR). Submaximal parameters of oxygen uptake are equally useful in SLE PAH. PMID- 29566673 TI - Implementation of grip strength measurement in medicine for older people wards as part of routine admission assessment: identifying facilitators and barriers using a theory-led intervention. AB - BACKGROUND: Low grip strength in older inpatients is associated with poor healthcare outcomes including longer length of stay and mortality. Measuring grip strength is simple and inexpensive. However, it is not routinely used in clinical practice. We aimed to evaluate the implementation of grip strength measurement into routine clinical practice. METHODS: This implementation study was a mixed methods study based in five acute medical wards for older people in one UK hospital. Intervention design and implementation evaluation were based on Normalization Process Theory (NPT). A training program was developed and delivered to enable staff to measure grip strength and use a care plan for patients with low grip strength. Routine implementation and monitoring was assessed using the "implementation outcome variables" proposed by WHO: adoption, coverage, acceptability, fidelity, and costs analysis. Enablers and barriers of implementation were identified. RESULTS: One hundred fifty-five nursing staff were trained, 63% in just 3 weeks. Adoption and monthly coverage of grip strength measurement varied between 25 and 80% patients across wards. 81% of female patients and 75% of male patients assessed had low grip strength (< 27 kg for men and < 16 kg for women). Staff and patients found grip measurement easy, cheap and potentially beneficial in identifying high-risk patients. The total cost of implementation across five wards over 12 months was less than L2302. Using NPT, interviews identified enablers and barriers. Enablers included: highly motivated ward champions, managerial support, engagement strategies, shared commitment, and integration into staff and ward daily routines. Barriers included lack of managerial and staff support, and high turnover of staff, managers and champions. CONCLUSIONS: Training a large number of nurses to routinely implement grip strength measurement of older patients was feasible, acceptable and inexpensive. Champions' motivation, managerial support, and shared staff commitment were important for the uptake and normalisation of grip strength measurement. A high percentage of older patients were identified to be at risk of poor healthcare outcomes and would benefit from nutritional and exercise interventions. Measuring grip strength in these patients could provide an opportunity to identify those with normal grip strength for fast tracking through admission to discharge thereby reducing length of stay.

PMID- 29566674 TI - A genome-wide association study identifies candidate loci associated to syringomyelia secondary to Chiari-like malformation in Cavalier King Charles Spaniels. AB - BACKGROUND: Syringomyelia (SM) is a common condition affecting brachycephalic toy breed dogs and is characterized by the development of fluid-filled cavities within the spinal cord. It is often concurrent with a complex developmental malformation of the skull and craniocervical vertebrae called Chiari-like malformation (CM) characterized by a conformational change and overcrowding of the brain and cervical spinal cord particularly at the craniocervical junction. CM and SM have a polygenic mode of inheritance with variable penetrance. RESULTS: We identified six cranial T1-weighted sagittal MRI measurements that were associated to maximum transverse diameter of the syrinx cavity. Increased syrinx transverse diameter has been correlated previously with increased likelihood of behavioral signs of pain. We next conducted a whole genome association study of these traits in 65 Cavalier King Charles Spaniel (CKCS) dogs (33 controls, 32 with extreme phenotypes). Two loci on CFA22 and CFA26 were found to be significantly associated to two traits associated with a reduced volume and altered orientation of the caudal cranial fossa. Their reconstructed haplotypes defined two associated regions that harbor only two genes: PCDH17 on CFA22 and ZWINT on CFA26. PCDH17 codes for a cell adhesion molecule expressed specifically in the brain and spinal cord. ZWINT plays a role in chromosome segregation and its expression is increased with the onset of neuropathic pain. Targeted genomic sequencing of these regions identified respectively 37 and 339 SNPs with significantly associated P values. Genotyping of tagSNPs selected from these 2 candidate loci in an extended cohort of 461 CKCS (187 unaffected, 274 SM affected) identified 2 SNPs on CFA22 that were significantly associated to SM strengthening the candidacy of this locus in SM development. CONCLUSIONS: We identified 2 loci on CFA22 and CFA26 that contained only 2 genes, PCDH17 and ZWINT, significantly associated to two traits associated with syrinx transverse diameter. The locus on CFA22 was significantly associated to SM secondary to CM in the CKCS dog breed strengthening its candidacy for this disease. This study will provide an entry point for identification of the genetic factors predisposing to this condition and its underlying pathogenic mechanisms. PMID- 29566675 TI - Development of the great recess framework - observational tool to measure contextual and behavioral components of elementary school recess. AB - BACKGROUND: Physical activity (PA) remains the primary behavioral outcome associated with school recess, while many other potentially relevant indicators of recess remain unexamined. Few studies have assessed observations of teacher/student interactions, peer conflict, social interactions, or safety within the recess environment. Furthermore, a psychometrically-sound instrument does not exist to examine safety, resources, student engagement, adult engagement, pro-social/anti-social behavior, and student empowerment on the playground. The purpose of the current study was to develop a valid, and reliable, assessment tool intended for use in measurement of the contextual factors associated with recess. METHODS: An iterative and multi-step process was used to develop a tool that measures safety and structure, adult engagement and supervision, student behaviors, and transitions at recess. Exploratory structural equation modeling (Mplus v. 7.4) was used to examine the underlying measurement model with observational data of the recess environment collected at 649 school based recess periods that spanned across 22 urban/metropolitan areas in the USA. Data were also collected by two researchers at 162 recess sessions across 9 schools to examine reliability. RESULTS: A 17-item observation instrument, the Great Recess Framework - Observational Tool (GRF-OT), was created. Findings of exploratory structural equation modeling (ESEM) analyses supported factorial validity for a 4-factor solution and linear regressions established convergent validity where 'structure and safety', 'adult engagement and supervision', and 'student behaviors' were all significantly related to observed activity levels. Each sub-scale of the GRF-OT showed adequate levels of inter-rater reliability and test-retest reliability analysis indicated a higher level of stability for the GRF-OT when using a three-day average across two time points as compared to a two-day average. CONCLUSIONS: Initial evidence for a valid, and reliable, assessment tool to observationally measure the recess environment with a specific focus on safety, resources, student engagement, adult engagement, pro-social/anti social behavior, and student empowerment was established in this study. Use of the GRF-OT can inspire evaluation, and subsequent intervention, to strategically create consistent, appropriate, and engaging school recess that impact children's physical, cognitive, social and emotional development.

PMID- 29566678 TI - Impact of a 15-month multi-channel continuous distribution pilot on ITN ownership and access in Eastern Region, Ghana. AB - BACKGROUND: Insecticide-treated nets are a key intervention for malaria prevention. While mass distribution can rapidly scale up ITN coverage, multiple channels may be needed to sustain high levels of ITN access and ownership. In Ghana's Eastern Region, a continuous ITN distribution pilot, started in October 2012, 18-24 months after a mass campaign. The pilot distributed ITNs through antenatal care services (ANC), child welfare clinic services (CWC) through the Expanded Programme on Immunization, and to students in two classes of primary schools. METHODS: ITN ownership and access were evaluated through two cross sectional surveys, conducted at baseline in April 2012, 11-15 months after the mass campaign, and at endline in December 2013, after 1 year of continuous distribution. A representative sample was obtained using a multi-stage cluster sampling design. Household heads were interviewed using a structured questionnaire. RESULTS: Household ownership of at least one ITN was 91.3% (95% CI 88.8-93.9) at baseline and was not statistically significant at endline 18 months later at 88.3% (95% CI 84.9-91.0) (p = 0.10). Ownership of at least 1 ITN per two people significantly decreased from 51.3% (95% CI 47.1-55.4) to 40.2% (95% CI 36.4-44.6) (p < 0.01). Population access to an ITN within the household also significantly decreased from 74.5% (95% CI 71.2-77.7) at baseline to 66.4% (95% CI 62.9-69.9) at endline (p < 0.01). The concentration index score for any CD channel was slightly positive (0.10; 95% CI 0.04-0.15). CONCLUSION: Thirty-one months after the mass campaign, the 15 months of continuous distribution activities had maintained levels of household ownership at least one ITN, but household ownership of one ITN for every two people and population access to ITN had declined. Ownership and access were higher with the CD programme than without. However, the number of ITNs delivered via ANC, CWC and two primary school classes were insufficient to sustain coverage targets. Future programmes should implement continuous distribution strategies fully within 1 year after a campaign or widen eligibility criteria (such as increase the number of classes) during the first year of implementation to make up for programme delays. PMID- 29566677 TI - Acidosis and acute kidney injury in severe malaria. AB - BACKGROUND: In severe falciparum malaria metabolic acidosis and acute kidney injury (AKI) are independent predictors of a fatal outcome in all age groups. The relationship between plasma acids, urine acids and renal function was investigated in adult patients with acute falciparum malaria. METHODS: Plasma and urinary acids which previously showed increased concentrations in proportion to disease severity in patients with severe falciparum malaria were quantified. Patients with uncomplicated malaria, sepsis and healthy volunteers served as comparator groups. Multiple regression and multivariate analysis were used to assess the relationship between organic acid concentrations and clinical syndromes, in particular AKI. RESULTS: Patients with severe malaria (n = 90), uncomplicated malaria (n = 94), non-malaria sepsis (n = 19), and healthy volunteers (n = 61) were included. Univariate analysis showed that both plasma and creatinine-adjusted urine concentrations of p-hydroxyphenyllactic acid (pHPLA) were higher in severe malaria patients with AKI (p < 0.001). Multiple regression analysis, including plasma or creatinine-adjusted urinary acids, and PfHRP2 as parasite biomass marker as independent variables, showed that pHPLA was independently associated with plasma creatinine (beta = 0.827) and urine creatinine (beta = 0.226). Principal component analysis, including four plasma acids and seven urinary acids separated a group of patients with AKI, which was mainly driven by pHPLA concentrations. CONCLUSIONS: Both plasma and urine concentrations of pHPLA closely correlate with AKI in patients with severe falciparum malaria. Further studies will need to assess the potential nephrotoxic properties of pHPLA. PMID- 29566679 TI - The in vitro estrogenic activity of the crude drugs found in Japanese herbal medicines prescribed for menopausal syndrome was enhanced by combining them. AB - BACKGROUND: Japanese herbal medicines can be used as alternatives to estrogen therapy and are sometimes prescribed for menopausal syndrome because they have fewer side effects and are associated with better compliance than estrogen therapy, but little is known about the pharmacological mechanisms of such treatments. This study aimed to explore the mechanisms responsible for the estrogen-like effects of five widely prescribed Japanese herbal medicines (unkeito, kamishoyosan, nyoshinsan, keishibukuryogan, and tokishakuyakusan). METHODS: We evaluated the estrogenic activity of these five Japanese herbal medicines and their metabolites using an estrogen receptor (ER)-dependent cell proliferation bioassay and an ER-dependent reporter assay. We also investigated the estrogenic activity of the crude drugs within the medicines and attempted to detect inter-crude drug synergistic effects using the ER-dependent reporter assay. RESULTS: We found that unkeito, kamishoyosan, and nyoshinsan exhibited estrogenic activity, and they displayed stronger estrogenic activity after being metabolized. Then, we focused on investigating the estrogenic activity of the crude drugs present within unkeito. We found that glycyrrhizae radix, cinnamomi cortex, evodiae fructus, and zingiberis rhizoma demonstrated ERbeta-dependent estrogenic activity. The combined use of evodiae fructus and glycyrrhizae radix, or evodiae fructus and cinnamomi cortex produced synergistic ERbeta-dependent estrogenic activity. CONCLUSION: It was suggested that unkeito, kamishoyosan, and nyoshinsan exert estrogenic activity, and hence, might be useful for treating menopausal syndrome. Furthermore, synergistic estrogenic effects were detected between some of the crude drugs present within unkeito. PMID- 29566680 TI - Process evaluations of task sharing interventions for perinatal depression in low and middle income countries (LMIC): a systematic review and qualitative meta synthesis. AB - BACKGROUND: Perinatal depression is common in low and middle income countries (LAMICs). Task sharing interventions have been implemented to treat perinatal depression in these settings, as a way of dealing with staff shortages. Task sharing allows lay health workers to provide services for less complex cases while being trained and supervised by specialists. Randomized controlled trials suggest that these interventions can be effective but there is limited qualitative information exploring barriers and facilitators to their implementation. This systematic review aims to systematically review current qualitative evidence of process evaluations of task sharing interventions for perinatal depression in LAMICs in relation to the United Kingdom (UK) Medical Research Council (MRC) framework for conducting process evaluations. METHODS: We searched Medline/ PubMed, PsycINFO, Scopus, Cochrane Library and Web of science for studies from LAMICS using search terms under the broad categories of: (a) "maternal depression'" (b) "intervention" (c) "lay counsellor" OR "community health worker" OR "non-specialist" and (d) "LAMICs". Abstracts were independently reviewed for inclusion by two authors. Full text articles were screened and data for included articles were extracted using a standard data extraction sheet. Qualitative synthesis of qualitative evidence was conducted. RESULTS: 8420 articles were identified from initial searches. Of these, 26 full text articles were screened for eligibility with only three studies meeting the inclusion criteria. Main findings revealed that participants identified the following crucial factors: contextual factors included physical location, accessibility and cultural norms. Implementation factors included acceptability of the intervention and characteristics of the personnel. Mechanisms included counsellor factors such as motivating and facilitating trust; intervention factors such as use of stories and visual aids, and understandability of the content; and participant factors such as shared experience, meeting learning needs, and meeting expectations. CONCLUSIONS: While task sharing has been suggested as an effective way of filling the treatment gap for perinatal depression, there is a paucity of qualitative research exploring barriers and facilitators to implementing these interventions. Qualitative process evaluations are crucial for the development of culturally relevant interventions. PMID- 29566681 TI - Mapping staff perspectives towards the delivery of hospital care for children and young people with and without learning disabilities in England: a mixed methods national study. AB - BACKGROUND: Children and young people (CYP) with learning disabilities (LD) are a vulnerable population with increased risk of abuse and accidental injury and whose parents have reported concerns about the quality, safety and accessibility of their hospital care. The Care Quality Commission's (CQC) view of best practice for this group of patients includes: access to senior LD nurse provision; a clearly visible flagging system for identifying them; the use of hospital passports; and defined communication strategies (Glasper, Comp Child Adolesc Nurs 40:63-67, 2017). What remains unclear is whether these recommendations are being applied and if so, what difference they are making. Furthermore, what we do not know is whether parental concerns of CYP with LD differ from parents of other children with long-term conditions. The aims of this study were to 1) describe the organisational context for healthcare delivery to CYP with LD and their families and 2) compare staff perceptions of their ability to identify the needs of CYP with and without LD and their families and provide high quality care to effectively meet these needs. METHODS: Individual interviews (n = 65) and anonymised online survey (n = 2261) were conducted with hospital staff working with CYP in 15 children's and 9 non-children's hospitals in England. The majority of interviews were conducted over the telephone and recorded and transcribed verbatim. Health Research Authority was obtained and verbal or written consent for data collection was obtained from all interview participants. RESULTS: The nature and extent of organisational policies, systems and practices in place within hospitals to support the care of CYP with LD differs across England and some uncertainty exists within and across hospitals as to what is currently available and accessed. Staff perceived that those with LD were included less, valued less, and less safe than CYP without LD. They also reported having less confidence, capability and capacity to meet the needs of this population compared to those without LD. CONCLUSION: Findings indicate inequality with regards the provision of high quality hospital care to children and young people with LD that meets their needs. There is a pressing need to understand the impact this has on them and their families. TRIAL REGISTRATION: The study has been registered on the NIHR CRN portfolio 20461 (Phase 1), 31336 (Phases 2-4). PMID- 29566682 TI - Investigating insecticide resistance and knock-down resistance (kdr) mutation in Dielmo, Senegal, an area under long lasting insecticidal-treated nets universal coverage for 10 years. AB - BACKGROUND: The use of insecticides, through indoor residual spraying and long lasting insecticide-treated nets (LLINs), is essential to control malaria vectors. However, the sustainability of these tools is challenged by the spread of insecticide resistance in Anopheles mosquitoes. This study was conducted to assess the susceptibility to insecticides and to determine the resistance mechanisms in malaria vectors in Dielmo, a rural area of western Senegal where LLINs were introduced a decade ago. METHODS: CDC bottle bioassays were used to determine the susceptibility of 2-5 day-old unfed Anopheles gambiae s.l. females to alphacypermethrin (12.5 ug/bottle), deltamethrin (12.5 ug/bottle), etofenprox (12.5 ug/bottle), lambdacyhalothrin (12.5 ug/bottle), permethrin (21.5 ug/bottle), DDT (100 ug/bottle), bendiocarb (12.5 ug/bottle), pirimiphos-methyl (20 ug/bottle) and fenitrothion (50 ug/bottle). The involvement of glutathione-S transferases (GSTs) in insecticide resistance was assessed using a synergist, etacrynic acid (EA, 80 ug/bottle). Polymerase chain reaction (PCR) was used to investigate the presence of 'knock-down resistance (kdr)' mutation and to identify sibling species within the An. gambiae complex. RESULTS: CDC bottle bioassays showed that mosquitoes were fully susceptible to lambdacyhalothrin, bendiocarb and fenitrothion. Overall, mortality rates of 97, 94.6, 93.5, 92.1, and 90.1% were, respectively, observed for permethrin, deltamethrin, pirimiphos methyl, etofenprox and alphacypermethrin. Resistance to DDT was observed, with a mortality rate of 62%. The use of EA significantly improved the susceptibility of An. gambiae s.l. to DDT by inhibiting GSTs (p = 0.03). PCR revealed that Anopheles arabiensis was the predominant species (91.3%; IC 95 86.6-94%) within An. gambiae complex from Dielmo, followed by Anopheles coluzzii (5.4%; IC 95 2.7 8.1%) and Anopheles gambiae s.s. (3.3%; IC 95 0.6-5.9%). Both 1014F and 1014S alleles were found in An. arabiensis population with frequencies of 0.08 and 0.361, respectively, and 0.233 and 0.133, respectively in An. coluzzii. In An. gambiae s.s. population, only kdr L1014F mutation was detected, with a frequency of 0.167. It was observed that some individual mosquitoes carried both alleles, with 19 specimens recorded for An. arabiensis and 2 for An. coluzzii. The presence of L1014F and L1014S alleles were not associated with resistance to pyrethroids and DDT in An. arabiensis. CONCLUSIONS: The co-occurrence of 1014F and 1014S alleles and the probable involvement of GSTs enzymes in insecticide resistance in An. gambiae s.l. should prompt the local vector programme to implement non-pyrethroid/DDT insecticides alternatives. PMID- 29566683 TI - Population pharmacokinetic and pharmacodynamic properties of artesunate in patients with artemisinin sensitive and resistant infections in Southern Myanmar. AB - BACKGROUND: Artemisinins are the most effective anti-malarial drugs for uncomplicated and severe Plasmodium falciparum malaria. However, widespread artemisinin resistance in the Greater Mekong Region of Southeast Asia is threatening the possibility to control and eliminate malaria. This work aimed to evaluate the pharmacokinetic and pharmacodynamic properties of artesunate and its active metabolite, dihydroartemisinin, in patients with sensitive and resistant falciparum infections in Southern Myanmar. In addition, a simple nomogram previously developed to identify artemisinin resistant malaria infections was evaluated. METHODS: Fifty-three (n = 53) patients were recruited and received daily oral artesunate monotherapy (4 mg/kg) for 7 days. Frequent artesunate and dihydroartemisinin plasma concentration measurements and parasite microscopy counts were obtained and evaluated using nonlinear mixed-effects modelling. RESULTS: The absorption of artesunate was best characterized by a transit compartment (n = 3) model, followed by one-compartment disposition models for artesunate and dihydroartemisinin. The drug-dependent parasite killing effect of dihydroartemisinin was described using an Emax function, with a mixture model discriminating between artemisinin sensitive and resistant parasites. Overall, 56% of the studied population was predicted to have resistant malaria infections. Application of the proposed nomogram to identify artemisinin-resistant malaria infections demonstrated an overall sensitivity of 90% compared to 55% with the traditional day-3 positivity test. CONCLUSION: The pharmacokinetic pharmacodynamic properties of artesunate and dihydroartemisinin were well characterized with a mixture model to differentiate between drug sensitive and resistant infections in these patients. More than half of all patients recruited in this study had artemisinin-resistant infections. The relatively high sensitivity of the proposed nomogram highlights its potential clinical usefulness. PMID- 29566684 TI - Effect of peer support interventions on cardiovascular disease risk factors in adults with diabetes: a systematic review and meta-analysis. AB - BACKGROUND: Peer support by persons affected with diabetes improves peer supporter's diabetes self-management skills. Peer support interventions by individuals who have diabetes or are affected by diabetes have been shown to improve glycemic control; however, its effects on other cardiovascular disease risk factors in adults with diabetes are unknown. We aimed to estimate the effect of peer support interventions on cardiovascular disease risk factors other than glycemic control in adults with diabetes. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials comparing peer support interventions to a control condition in adults affected by diabetes that measured any cardiovascular disease risk factors [Body Mass Index, smoking, diet, physical activity, cholesterol level, glucose control and blood pressure]. Quality was assessed by Cochrane's risk of bias tool. We calculated standardized mean difference effect sizes using random effects models. RESULTS: We retrieved 438 citations from multiple databases including OVID MEDLINE, Cochrane database and Scopus, and author searches. Of 233 abstracts reviewed, 16 articles met inclusion criteria. A random effects model in a total of 3243 participants showed a positive effect of peer support interventions on systolic BP with a pooled effect size of 2.07 mmHg (CI 0.35 mmHg to 3.79 mmHg, p = 0.02); baseline pooled systolic blood pressure was 137 mmHg. There was a non-significant effect of peer support interventions on diastolic blood pressure, cholesterol, body mass index, diet and physical activity. Cardiovascular disease risk factors other than glycemic control outcomes were secondary outcomes in most studies and baseline values were normal or mildly elevated. Only one study reported smoking outcomes. CONCLUSIONS: We found a small (2 mmHg) positive effect of peer support interventions on systolic blood pressure in adults with diabetes whose baseline blood pressure was on average minimally elevated. Additional studies need to be conducted to further understand the effect of peer support interventions on high-risk cardiovascular disease risk factors in adults with diabetes. PMID- 29566685 TI - Polymorphisms analysis of the Plasmodium ovale tryptophan-rich antigen gene (potra) from imported malaria cases in Henan Province. AB - BACKGROUND: Plasmodium ovale has two different subspecies: P. ovale curtisi and P. ovale wallikeri, which may be distinguished by the gene potra encoding P. ovale tryptophan-rich antigen. The sequence and size of potra gene was variable between the two P. ovale spp., and more fragment sizes were found compared to previous studies. Further information about the diversity of potra genes in these two P. ovale spp. will be needed. METHODS: A total of 110 dried blood samples were collected from the clinical patients infected with P. ovale, who all returned from Africa in Henan Province in 2011-2016. The fragments of potra were amplified by nested PCR. The sizes and species of potra gene were analysed after sequencing, and the difference between the isolates were analysed with the alignment of the amino acid sequences. The phylogenetic tree was constructed by neighbour-joining to determine the genetic relationship among all the isolates. The distribution of the isolates was analysed based on the origin country. RESULTS: Totally 67 samples infected with P. o. wallikeri, which included 8 genotypes of potra, while 43 samples infected with P. o. curtisi including 3 genotypes of potra. Combination with the previous studies, P. o. wallikeri had six sizes, 227, 245, 263, 281, 299 and 335 bp, and P. o. curtisi had four sizes, 299, 317, 335 and 353 bp, the fragment sizes of 299 and 335 bp were the overlaps between the two species. Six amino acid as one unit was firstly used to analyse the amino acid sequence of potra. Amino acid sequence alignment revealed that potra of P. o. wallikeri differed in two amino acid units, MANPIN and AITPIN, while potra of P. o. curtisi differed in amino acid units TINPIN and TITPIS. Combination with the previous studies, there were ten subtypes of potra exiting for P. o. wallikeri and four subtypes for P. o. curtisi. The phylogenetic tree showed that 11 isolates were divided into two clusters, P. o. wallikeri which was then divided into five sub-clusters, and P. o. curtisi which also formed two sub clusters with their respective reference sequences. The genetic relationship of the P. ovale spp. mainly based on the number of the dominant amino acid repeats, the number of MANPIN, AITPIN, TINPIN or TITPIS. The genotype of the 245 bp size for P. o. wallikeri and that of the 299 and 317 bp size for P. o. curtisi were commonly exiting in Africa. CONCLUSION: This study further proved that more fragment sizes were found, P. o. wallikeri had six sizes, P. o. curtisi had four sizes. There were ten subtypes of potra exiting for P. o. wallikeri and four subtypes for P. o. curtisi. The genetic polymorphisms of potra provided complementary information for the gene tracing of P. ovale spp. in the malaria elimination era. PMID- 29566686 TI - Synthesis of avenanthramides using engineered Escherichia coli. AB - BACKGROUND: Hydroxycinnamoyl anthranilates, also known as avenanthramides (avns), are a group of phenolic alkaloids with anti-inflammatory, antioxidant, anti-itch, anti-irritant, and antiatherogenic activities. Some avenanthramides (avn A-H and avn K) are conjugates of hydroxycinnamic acids (HC), including p-coumaric acid, caffeic acid, and ferulic acid, and anthranilate derivatives, including anthranilate, 4-hydroxyanthranilate, and 5-hydroxyanthranilate. Avns are primarily found in oat grain, in which they were originally designated as phytoalexins. Knowledge of the avns biosynthesis pathway has now made it possible to synthesize avns through a genetic engineering strategy, which would help to further elucidate their properties and exploit their beneficial biological activities. The aim of the present study was to synthesize natural avns in Escherichia coli to serve as a valuable resource. RESULTS: We synthesized nine avns in E. coli. We first synthesized avn D from glucose in E. coli harboring tyrosine ammonia lyase (TAL), 4-coumarate:coenzyme A ligase (4CL), anthranilate N hydroxycinnamoyl/benzoyltransferase (HCBT), and anthranilate synthase (trpEG). A trpD deletion mutant was used to increase the amount of anthranilate in E. coli. After optimizing the incubation temperature and cell density, approximately 317.2 mg/L of avn D was synthesized. Avn E and avn F were then synthesized from avn D, using either E. coli harboring HpaBC and SOMT9 or E. coli harboring HapBC alone, respectively. Avn A and avn G were synthesized by feeding 5-hydroxyanthranilate or 4-hydroxyanthranilate to E. coli harboring TAL, 4CL, and HCBT. Avn B, avn C, avn H, and avn K were synthesized from avn A or avn G, using the same approach employed for the synthesis of avn E and avn F from avn D. CONCLUSIONS: Using different HCs, nine avns were synthesized, three of which (avn D, avn E, and avn F) were synthesized from glucose in E. coli. These diverse avns provide a strategy to synthesize both natural and unnatural avns, setting a foundation for exploring the biological activities of diverse avns. PMID- 29566687 TI - "It was the whole picture" a mixed methods study of successful components in an integrated wellness service in North East England. AB - BACKGROUND: A growing number of Local Authorities (LAs) have introduced integrated wellness services as part of efforts to deliver cost effective, preventive services that address the social determinants of health. This study examined which elements of an integrated wellness service in the north east of England were effective in improving health and wellbeing (HWB). METHODS: The study used a mixed-methods approach. In-depth semi-structured interviews (IVs) were conducted with integrated wellness service users (n = 25) and focus groups (FGs) with group based service users (n = 14) and non-service users (n = 23) to gather the views of stakeholders. Findings are presented here alongside analysis of routine monitoring data. The different data were compared to examine what each data source revealed about the effectiveness of the service. RESULTS: Findings suggest that integrated wellness services work by addressing the social determinants of health and respond to multiple complex health and social concerns rather than single issues. The paper identifies examples of 'active ingredients' at the heart of the programme, such as sustained relationships, peer support and confidence building, as well as the activities through which changes take place, such as sports and leisure opportunities which in turn encourage social interaction. Wider wellbeing outcomes, including reduced social isolation and increased self-efficacy are also reported. Practical and motivational support helped build community capacity by encouraging community groups to access funding, helped navigate bureaucratic systems, and promoted understanding of marginalised communities. Fully integrated wellness services could support progression opportunities through volunteering and mentoring. CONCLUSIONS: An integrated wellness service that offers a holistic approach was valued by service users and allowed them to address complex issues simultaneously. Few of the reported health gains were captured in routine data. Quantitative and qualitative data each offered a partial view of how effectively services were working. PMID- 29566688 TI - Implementation of knowledge-based palliative care in nursing homes and pre-post post evaluation by cross-over design: a study protocol. AB - BACKGROUND: The demography of the world is changing as the population is ageing. Because of this change to a higher proportion of older people, the WHO has called for improved palliative care for older persons. A large number of all deaths in the industrialised world occur while older people are living in nursing homes and therefore a key question becomes how the principles of palliative care can be implemented in that context. The aims of this study are: a) to describe a model of an educational intervention with the goal of implementing knowledge-based palliative care in nursing homes, and b) to describe the design of the evaluation of the effectiveness regarding the implementation of knowledge-based palliative care. METHODS/DESIGN: A complex intervention is evaluated by means of a cross over design. An educational intervention concerning palliative care consisting of five seminars during 6 months for staff and managers has been developed and conducted in 20 nursing homes in two counties. Before the intervention started, the feasibility was tested in a pilot study conducted in nursing homes not included in the main study. The intervention is evaluated through a non randomized experimental design with intervention and control groups and pre- and post-assessments. The evaluation includes older persons living in nursing homes, next-of-kin, staff and managers. Data collection consists of quantitative methods such as questionnaires and register data and qualitative methods in the form of individual interviews, focus-group interviews and participant observations. DISCUSSION: The research will contribute to new knowledge about how to implement knowledge-based palliative care in a nursing home setting. A strength of this project is that the Medical Research Council framework of complex intervention is applied. The four recommended stages, Development, Feasibility and piloting, Evaluation and Implementation, are combined for the educational intervention, which functions as a strategy to achieve knowledge-based palliative care in the nursing homes. Implementation is always a question of change and a good theoretical understanding is needed for drawing valid conclusions about the causal mechanisms of change. The topic is highly relevant considering the world's ageing population. The data collection is completed and the analysis is ongoing. TRIAL REGISTRATION: NCT02708498 . PMID- 29566689 TI - Brain injury rehabilitation after road trauma in new South Wales, Australia - insights from a data linkage study. AB - BACKGROUND: Population-based patterns of care studies are important for trauma care but conducting them is expensive and resource-intensive. Linkage of routinely collected administrative health data may provide an efficient alternative. The aims of this study are to describe the rehabilitation pathway for trauma survivors and to analyse the brain injury rehabilitation outcomes in the two care settings (specialist brain injury and non-specialist general rehabilitation units). METHODS: This is an observational study using routinely collected registry data (New South Wales Trauma Registry linked with the Australasian Rehabilitation Outcomes Centre Inpatient Dataset). The study cohort includes 268 road trauma patients who were admitted to trauma services between 2009 and 2012 and received inpatient rehabilitation because of a brain injury. RESULTS: Of those who need inpatient rehabilitation, 62% (n = 166) were admitted to specialist units with the remainder (n = 102) admitted to non-specialist units. Those admitted to a specialist units were younger (p < 0.001), had a lower cognitive FIM score (p = 0.003) on admission than those admitted to non specialist units. Specialist units achieved better overall FIM score improvements from admission to discharge (43 vs 30 points, p > 0.001) but at a cost of longer length of stay (median 47 vs 24 days, p < 0.001). There were very few discharges to residential aged care facilities from rehabilitation (2% in non-specialist units and none from specialist units). There was a long time lag between trauma and admission to inpatient rehabilitation with only a quarter of the patients admitted to a specialist unit by end of week four. Few older patients (19%) with brain injury were admitted to specialist units. CONCLUSIONS: It is feasible to use routinely collected registry data to monitor inpatient rehabilitation outcomes of trauma care. There were differences in characteristics and outcomes of patients with traumatic brain injury admitted to specialist units compared with non-specialist units. PMID- 29566690 TI - Use of chitin and chitosan to produce new chitooligosaccharides by chitinase Chit42: enzymatic activity and structural basis of protein specificity. AB - BACKGROUND: Chitinases are ubiquitous enzymes that have gained a recent biotechnological attention due to their ability to transform biological waste from chitin into valued chito-oligomers with wide agricultural, industrial or medical applications. The biological activity of these molecules is related to their size and acetylation degree. Chitinase Chit42 from Trichoderma harzianum hydrolyses chitin oligomers with a minimal of three N-acetyl-D-glucosamine (GlcNAc) units. Gene chit42 was previously characterized, and according to its sequence, the encoded protein included in the structural Glycoside Hydrolase family GH18. RESULTS: Chit42 was expressed in Pichia pastoris using fed-batch fermentation to about 3 g/L. Protein heterologously expressed showed similar biochemical properties to those expressed by the natural producer (42 kDa, optima pH 5.5-6.5 and 30-40 degrees C). In addition to hydrolyse colloidal chitin, this enzyme released reducing sugars from commercial chitosan of different sizes and acetylation degrees. Chit42 hydrolysed colloidal chitin at least 10-times more efficiently (defined by the kcat/Km ratio) than any of the assayed chitosan. Production of partially acetylated chitooligosaccharides was confirmed in reaction mixtures using HPAEC-PAD chromatography and mass spectrometry. Masses corresponding to (D-glucosamine)1-8-GlcNAc were identified from the hydrolysis of different substrates. Crystals from Chit42 were grown and the 3D structure determined at 1.8 A resolution, showing the expected folding described for other GH18 chitinases, and a characteristic groove shaped substrate-binding site, able to accommodate at least six sugar units. Detailed structural analysis allows depicting the features of the Chit42 specificity, and explains the chemical nature of the partially acetylated molecules obtained from analysed substrates. CONCLUSIONS: Chitinase Chit42 was expressed in a heterologous system to levels never before achieved. The enzyme produced small partially acetylated chitooligosaccharides, which have enormous biotechnological potential in medicine and food. Chit42 3D structure was characterized and analysed. Production and understanding of how the enzymes generating bioactive chito-oligomers work is essential for their biotechnological application, and paves the way for future work to take advantage of chitinolytic activities. PMID- 29566691 TI - Use of a public-private partnership in malaria elimination efforts in Sri Lanka; a case study. AB - BACKGROUND: In special circumstances, establishing public private partnerships for malaria elimination may achieve targets faster than the state sector acting by itself. Following the end of the separatist war in Sri Lanka in 2009, the Anti Malaria Campaign (AMC) of Sri Lanka intensified malaria surveillance jointly with a private sector partner, Tropical and Environmental Diseases and Health Associates Private Limited (TEDHA) with a view to achieving malaria elimination targets by 2014. METHODS: This is a case study on how public private partnerships can be effectively utilized to achieve malaria elimination goals. TEDHA established 50 Malaria Diagnostic Laboratories and 17 entomology surveillance sentinel sites in consultation with the AMC in areas difficult to access by government officials (five districts in two provinces affected by war). RESULTS: TEDHA screened 994,448 individuals for malaria, of which 243,867 were screened at mobile malaria clinics as compared to 1,102,054 screened by the AMC. Nine malaria positives were diagnosed by TEDHA, while the AMC diagnosed 103 malaria cases in the same districts in parallel. Over 13,000 entomological activity days were completed. Relevant information was shared with AMC and the data recorded in the health information system. CONCLUSIONS: A successful public-private partnership model for malaria elimination was initiated at a time when the health system was in disarray in war ravaged areas of Sri Lanka. This ensured a high annual blood examination rate and screening of vulnerable people in receptive areas. These were important for certification of malaria-free status which Sri Lanka eventually received in 2016. PMID- 29566692 TI - Geographic assessment of access to health care in patients with cardiovascular disease in South Africa. AB - BACKGROUND: Noncommunicable diseases (NCDs) including cardiovascular diseases (CVDs), diabetes, cancer and chronic lung disease are increasingly emerging as major contributors to morbidity and mortality in developing countries. For example, in South Africa, 195 people died per day between 1997 and 2004 from CVDs related causes. Access to efficient and effective health facility and care is an important contributing factor to overall population health and addressing prognosis, care and management CVD disease burden. This study aimed to spatially evaluate geographic health care access of people diagnosed with CVD to health facilities and to evaluate the density of the existing health facility network in South Africa. METHODS: Data was obtained from the National Income Dynamics Study (NIDS) conducted in 4 waves (phases) between 2008 and 2014. The participants who responded as having heart problems that were diagnosed by a health practitioner were extracted for use in this study. Network analyst in ArcGIS (r) was used to generate a least-cost path, which refers to the best path that one can travel. The residential locations of participants diagnosed with heart problems were put into the network analysis model as origins and the location of health facilities were destinations. District averages were used to protect the identity of studied participants. RESULTS: There were a total of 51, 42, 43, 43 health districts out the 52 that had recorded subjects with a heart condition in the 2008, 2010-2011, 2012 and 2014-2015 waves, respectively. The mean distance from a case household to a health facility per wave was 2, 2.3, 2.1 and 2.1 km in 2008, 2010-2011 and 2014-2015 respectively. The maximum individual distances travelled per wave were 41.4 km, 40,5 km, 44,2 km and 39.6 km for the 2008, 2010-2011, 2012 and 2014-2015 waves respectively. For district level analysis, participants with CVD residing in the districts found to be among the poorest in the country travelled the longest distances. These were located in the provinces of Limpopo and KwaZulu Natal. It was also found that districts with large proportions of their population living in rural settings had among the lowest densities of health facilities. Significant percentages of study participants were exposed to numerous CVD risk factors, the commonly reported one being high blood pressure. A lack of regular exercise was also commonly reported in each of the waves. CONCLUSION: A lack of accessible healthcare in already impoverished municipalities could result in an increase lack of timely diagnosis, CVD case management. This could result in increased CVD-related morbidity and mortality. GIS methods have the potential to assist national health programs to develop policies that target issues such as areas or populations being underserved by health facilities and populations that must travel long distances to receive healthcare. These policies will be key in preventing and controlling the emerging CVD burden through an accessible primary healthcare system for early detection and case management. PMID- 29566693 TI - Potentiating and synergistic effect of grapefruit juice on the antioxidant and anti-inflammatory activity of aripiprazole against hydrogen peroxide induced oxidative stress in mice. AB - BACKGROUND: Dependence on antipsycotic drugs like aripriprazole (ARI) is increasing at alarming rate, hence, this study was undertaken to support the hypothesis that supplementation of Citrus paradisi (Grapefruit) juice having high concentration of polyphenols might potentiate and synergize the therapeutic effect of ARI, by increasing its bioavailability and inherent antioxidant potential. These benefits together might decrease the daily dosage of the ARI and thus alleviate the possible side effects of drug. METHODS: In this study the antioxidant and anti-inflammatory potential of ARI alone and in combination with GFJ was evaluated for hydrogen peroxide (H2O2) induced oxidative stress in mice. Seventy mice (4 weeks old), were randomly divided into seven groups. Group I: Control; Group II: H2O2 treated; Group III; ARI treated; Group IV GFJ treated; Group V: GFJ and H2O2 treated; Group VI; ARI and H2O2 treated; Group VII; ARI, GFJ and H2O2 treated. Serum levels of alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine kinase (CK), creatinine and total protein were measured. Furthermore, pro-inflammatory cytokines Interleukin (IL)-1alpha, IL-2, IL-10 and tumor necrosis factor-alpha (TNF-alpha) concentrations were also measured. RESULTS: The mice group that was treated with ARI, GFJ or combination of the two showed significant improvement in the H2O2 altered parameters with the combination group showing more significant improvement than the ARI and GFJ alone groups indicating a synergistic and potentiating effect of the antioxidant and anti-inflammatory potential of GFJ on ARI. CONCLUSION: Supplementing GFJ to ARI might increase an anti-oxidative potential of ARI due to inherent antioxidant and anti-inflammatory activity of GFJ and thus could alleviate the possible dosage dependent side effects of ARI. PMID- 29566694 TI - 4-Acetylantroquinonol B inhibits lipopolysaccharide-induced cytokine release and alleviates sepsis through of MAPK and NFkappaB suppression. AB - BACKGROUND: Antrodia cinnamomea is an indigenous medicinal mushroom in Taiwan, commonly used for the treatment of cancers and inflammatory disorders. 4 acetylantroquinonol B (4AAQB) is one of the active component isolated from the mycelium of A. cinnamomea. However, whether 4AAQB exhibits anti-inflammatory effect is not clear. METHODS: The anti-inflammatory activity of 4AAQB was examined by ELISA to measure the pro-inflammatory cytokines production in lipopolysaccharide (LPS)-simulated RAW264.7 cells, peritoneal macrophages and in mice. The effect of 4AAQB for MAPK kinase molecules phosphorylation in LPS stimulated RAW264.7 macrophage including ERK, JNK and p38 were evaluated. The in vivo efficacy of 4AAQB was also demonstrated. RESULTS: In the present study, we found that 4AAQB exhibits anti-inflammatory effects inhibit tumor necrosis factor alpha (TNF-alpha)/interleukin-6 (IL-6) releasing and LPS-stimulated phagocytes migration without affect cell growth. In addition, the MAPK kinase molecules phosphorylation in LPS-stimulated RAW264.7 macrophage including ERK, JNK and p38 was inhibited by 4AAQB. The phosphorylation of NFkappaB subunit p65 and IkBalpha were also decreased after 4AAQB treatment. Furthermore, 4AAQB attenuates the cytokine production in LPS-induced and CLP-induced septic mice. CONCLUSION: These results showed that 4AAQB exhibited anti-inflammatory property both in vitro and in vivo, suggesting that 4AAQB may be a therapeutic candidate which used in inflammatory disorders treatment. PMID- 29566695 TI - Cerebrospinal fluid Plasmodium falciparum histidine-rich protein-2 in pediatric cerebral malaria. AB - BACKGROUND: Cerebral malaria (CM) causes a rapidly developing coma, and remains a major contributor to morbidity and mortality in malaria-endemic regions. This study sought to determine the relationship between cerebrospinal fluid (CSF) Plasmodium falciparum histidine rich protein-2 (PfHRP-2) and clinical, laboratory and radiographic features in a cohort of children with retinopathy-positive CM. METHODS: Patients included in the study were admitted (2009-2013) to the Pediatric Research Ward (Queen Elizabeth Central Hospital, Blantyre, Malawi) meeting World Health Organization criteria for CM with findings of malarial retinopathy. Enzyme-linked immunosorbent assay was used to determine plasma and CSF PfHRP-2 levels. Wilcoxon rank-sum tests and multivariable logistic regression analysis assessed the association of clinical and radiographic characteristics with the primary outcome of death during hospitalization. RESULTS: In this cohort of 94 patients, median age was 44 (interquartile range 29-62) months, 53 (56.4%) patients were male, 6 (7%) were HIV-infected, and 10 (11%) died during hospitalization. Elevated concentrations of plasma lactate (p = 0.005) and CSF PfHRP-2 (p = 0.04) were significantly associated with death. On multivariable analysis, higher PfHRP-2 in the CSF was associated with death (odds ratio 9.00, 95% confidence interval 1.44-56.42) while plasma PfHRP-2 was not (odds ratio 2.05, 95% confidence interval 0.45-9.35). CONCLUSIONS: Elevation of CSF, but not plasma PfHRP-2, is associated with death in this paediatric CM cohort. PfHRP-2 egress into the CSF may represent alteration of blood brain barrier permeability related to the sequestration of parasitized erythrocytes in the cerebral microvasculature. PMID- 29566696 TI - How do NHS organisations plan research capacity development? Strategies, strengths, and opportunities for improvement. AB - Research that is integral into a 'learning healthcare system' can promote cost effective services and knowledge creation. As such, research is defined as a 'core function' in UK health service organisations, and is often planned through research and development (R&D) strategies that aim to promote research activity and research capacity development (RCD). The discussion focuses around the content of ten R&D strategies for healthcare organisations in England and Scotland, with respect to RCD. These organisations were engaged with a research interest network called ACORN (Addressing Organisational Capacity to do Research Network) that included two Scottish Health Boards, four community and mental health trusts, two provincial district hospitals, and two teaching hospitals. We undertook a thematic documentary analysis of the R&D strategies which identified 11 'core activities' of RCD. The potential for building research capacity in these 'core activities' was established by reviewing them through the lens of a RCD framework. Core activities aimed to 'hard wire' RCD into health organisations. They demonstrated a complex interplay between developing a strong internal organisational infrastructure, and supporting individual career planning and skills development, in turn enabled by organisational processes. They also included activities to build stronger inter-organisational relationships and networks. Practitioner, manager and patient involvement was a cross cutting theme. The potential to demonstrate progress was included in plans through monitoring activity across all RCD principles. Strategies were primarily aimed at research production rather than research use. Developing 'actionable dissemination' was poorly addressed in the strategies, and represents an area for improvement. We describe strengths of RCD planning activities, and opportunities for improvement. We explore how national policy and research funders can influence health systems' engagement in research. PMID- 29566697 TI - 'Broken hospital windows': debating the theory of spreading disorder and its application to healthcare organizations. AB - BACKGROUND: Research in criminology and social-psychology supports the idea that visible signs of disorder, both physical and social, may perpetuate further disorder, leading to neighborhood incivilities, petty violations, and potentially criminal behavior. This theory of 'broken windows' has now also been applied to more enclosed environments, such as organizations. MAIN TEXT: This paper debates whether the premise of broken windows theory, and the concept of 'disorder', might also have utility in the context of health services. There is already a body of work on system migration, which suggests a role for violations and workarounds in normalizing unwarranted deviations from safe practices in healthcare organizations. Studies of visible disorder may be needed in healthcare, where the risks of norm violations and disorderly environments, and potential for harm to patients, are considerable. Everyday adjustments and flexibility is mostly beneficial, but in this paper, we ask: how might deviations from the norm escalate from necessary workarounds to risky violations in care settings? Does physical or social disorder in healthcare contexts perpetuate further disorder, leading to downstream effects, including increased risk of harm to patients? CONCLUSIONS: We advance a model of broken windows in healthcare, and a proposal to study this phenomenon. PMID- 29566698 TI - Effectiveness of an oral health intervention program for children with congenital heart defects. AB - BACKGROUND: Children with congenital heart defects (CHD) are reported to have poorer oral health compared with healthy children. The aim of the present study was to evaluate the effectiveness of an intensive oral health care program among children with CHD followed from infancy to the age of 5 years, by comparing their oral health status at 5 years with a control group of children with CHD who had not received the program. METHODS: In this longitudinal study, children in western Norway with a need for lifelong follow-up due to congenital heart defects were invited to participate (n = 119). Children born in 2008-2011 were offered an oral health intervention program from infancy to the age of 5 years. The outcome measures for evaluating the intervention were dental caries prevalence, dental erosion, plaque index and gingival bleeding index. The data of the intervention group were compared with cross sectional oral health data of 5 year old controls with CHD born 2005-2007 (already published). RESULTS: Early oral health intervention did not affect the prevalence of caries (25.3% versus 25.4%) or dental erosion (22.2% versus 19.7%) of children with CHD assessed at 5 years. Children in the intervention group were less likely than those in the control group to present with both dental plaque and gingival bleeding at age 5 years. In spite of no difference in caries prevalence between the groups, caries affected children (d1-5mft) in the intervention group had fewer teeth affected by caries than children in the control group (p = 0.06). The care index was reported to be higher in the intervention group compared with the control group, implying that fewer children in the intervention group suffered from untreated dentine caries. Parents in the intervention group were more likely to brush their children's teeth twice a day than parents of children in the control group. CONCLUSION: The oral health promotive program did not influence the prevalence of caries nor dental erosion. However, the findings indicated better oral hygiene, reduced gingival bleeding and less untreated dentine caries in the intervention compared with the control group.

PMID- 29566699 TI - Integrative genomics identifies new genes associated with severe COPD and emphysema. AB - BACKGROUND: Genome-wide association studies have identified several genetic risk loci for severe chronic obstructive pulmonary disease (COPD) and emphysema. However, these studies do not fully explain disease heritability and in most cases, fail to implicate specific genes. Integrative methods that combine gene expression data with GWAS can provide more power in discovering disease associated genes and give mechanistic insight into regulated genes. METHODS: We applied a recently described method that imputes gene expression using reference transcriptome data to genome-wide association studies for two phenotypes (severe COPD and quantitative emphysema) and blood and lung tissue gene expression datasets. We further tested the potential causality of individual genes using multi-variant colocalization. RESULTS: We identified seven genes significantly associated with severe COPD, and five genes significantly associated with quantitative emphysema in whole blood or lung. We validated results in independent transcriptome databases and confirmed colocalization signals for PSMA4, EGLN2, WNT3, DCBLD1, and LILRA3. Three of these genes were not located within previously reported GWAS loci for either phenotype. We also identified genetically driven pathways, including those related to immune regulation. CONCLUSIONS: An integrative analysis of GWAS and gene expression identified novel associations with severe COPD and quantitative emphysema, and also suggested disease-associated genes in known COPD susceptibility loci.

PMID- 29566700 TI - Review of 14 drowning publications based on the Utstein style for drowning. AB - BACKGROUND: The Utstein style for drowning (USFD) was published in 2003 with the aim of improving drowning research. To support a revision of the USFD, the current study aimed to generate an inventory of the use of the USFD parameters and compare the findings of the publications that have used the USFD. METHODS: A search in Pubmed, Embase, the Cochrane Library, Web of Science and Scopus was performed to identify studies that used the USFD and were published between 01-10 2003 and 22-03-2015. We also searched in Pubmed, Embase, the Cochrane Library, Web of Science, and Scopus for all publications that cited the two publications containing the original ILCOR advisory statement introducing and recommending the USFD. In total we identified 14 publications by groups that explicitly used elements of the USFD for collecting and reporting their data. RESULTS: Of the 22 core and 19 supplemental USFD parameters, 6-19 core (27-86%) and 1-12 (5-63%) supplemental parameters were used; two parameters (5%) have not been used in any publication. Associations with outcome were reported for nine core (41%) and five supplemental (26%) USFD parameters. The USFD publications also identified non USFD parameters related to outcome: initial cardiac rhythm, time points and intervals during resuscitation, intubation at the drowning scene, first hospital core temperature, serum glucose and potassium, the use of inotropic/vasoactive agents and the Paediatric Index of Mortality 2-score. CONCLUSIONS: Fourteen USFD based drowning publications have been identified. These publications provide valuable information about the process and quality of drowning resuscitation and confirm that the USFD is helpful for a structured comparison of the outcome of drowning resuscitation.

PMID- 29566702 TI - A new CFD based non-invasive method for functional diagnosis of coronary stenosis. AB - BACKGROUND: Accurate functional diagnosis of coronary stenosis is vital for decision making in coronary revascularization. With recent advances in computational fluid dynamics (CFD), fractional flow reserve (FFR) can be derived non-invasively from coronary computed tomography angiography images (FFRCT) for functional measurement of stenosis. However, the accuracy of FFRCT is limited due to the approximate modeling approach of maximal hyperemia conditions. To overcome this problem, a new CFD based non-invasive method is proposed. METHODS: Instead of modeling maximal hyperemia condition, a series of boundary conditions are specified and those simulated results are combined to provide a pressure-flow curve for a stenosis. Then, functional diagnosis of stenosis is assessed based on parameters derived from the obtained pressure-flow curve. RESULTS: The proposed method is applied to both idealized and patient-specific models, and validated with invasive FFR in six patients. Results show that additional hemodynamic information about the flow resistances of a stenosis is provided, which cannot be directly obtained from anatomy information. Parameters derived from the simulated pressure-flow curve show a linear and significant correlations with invasive FFR (r > 0.95, P < 0.05). CONCLUSION: The proposed method can assess flow resistances by the pressure-flow curve derived parameters without modeling of maximal hyperemia condition, which is a new promising approach for non-invasive functional assessment of coronary stenosis. PMID- 29566703 TI - Cognitive impairment in metabolically-obese, normal-weight rats: identification of early biomarkers in peripheral blood mononuclear cells. AB - BACKGROUND: Metabolically-obese, normal-weight (MONW) individuals are not obese in terms of weight and height but have a number of obesity-related features (e.g. greater visceral adiposity, insulin resistance, and increased risk of cardiovascular disease). The MONW phenotype is related to the intake of unbalanced diets, such as those rich in fat. Increasing evidence shows a relationship between high-fat diet consumption and mild cognitive impairment and dementia. Thus, MONW individuals could be at a greater risk of cognitive dysfunction. We aimed to evaluate whether MONW-like animals present gene expression alterations in the hippocampus associated with an increased risk of cognitive impairment, and to identify early biomarkers of cognitive dysfunction in peripheral blood mononuclear cells (PBMC). METHODS: Wistar rats were chronically fed with a 60% (HF60) or a 45% (HF45) high-fat diet administered isocalorically to control animals to mimic MONW features. Expression analysis of cognitive decline-related genes was performed using RT-qPCR, and working memory was assessed using a T-maze. RESULTS: High-fat diet consumption altered the pattern of gene expression in the hippocampus, clearly pointing to cognitive decline, which was accompanied by a worse performance in the T-maze in HF60 animals. Remarkably, Syn1 and Sorl1 mRNA showed the same expression pattern in both the hippocampus and the PBMC obtained at different time-points in the HF60 group, even before other pathological signs were observed. CONCLUSIONS: Our results demonstrate that long-term intake of high-fat diets, even in the absence of obesity, leads to cognitive disruption that is reflected in PBMC transcriptome. Therefore, PBMC are revealed as a plausible, minimally-invasive source of early biomarkers of cognitive impairment associated with increased fat intake. PMID- 29566704 TI - A case of Cardiobacterium valvarum endocarditis with cerebral hemorrhage after MVR, TVP and vegetation removal operation. AB - BACKGROUND: Cardiobacterium is a fastidious Gram-negative bacillus, and is a rare human pathogen in clinical settings. Herein, we describe a case of Cardiobacterium valvarum (C. valvarum) endocarditis with a rare complication of cerebral hemorrhage after mitral valve replacement (MVR), tricuspid valve prosthesis (TVP) and vegetation removal operation. CASE PRESENTATION: A 41-year old woman who had a history of gingivitis developed into infective endocarditis due to the infection of C. valvarum. Then, she was hospitalized to receive MVR, TVP and vegetation removal operation. The indicators of patient tended to be normal until the abrupt cerebral hemorrhage occurred on day 15 after operation. This is the first well-described case of C. valvarum infection in China, and the first report of C. valvarum endocarditis with cerebral hemorrhage after MVR, TVP and vegetation removal operation worldwide. CONCLUSIONS: We reported the first case of C. valvarum infection in China clinically, with a rare complication of cerebral hemorrhage after MVR, TVP and vegetation removal operation. PMID- 29566705 TI - Renal autoregulation and blood pressure management in circulatory shock. AB - The importance of personalized blood pressure management is well recognized. Because renal pressure-flow relationships may vary among patients, understanding how renal autoregulation may influence blood pressure control is essential. However, much remains uncertain regarding the determinants of renal autoregulation in circulatory shock, including the influence of comorbidities and the effects of vasopressor treatment. We review published studies on renal autoregulation relevant to the management of acutely ill patients with shock. We delineate the main signaling pathways of renal autoregulation, discuss how it can be assessed, and describe the renal autoregulatory alterations associated with chronic disease and with shock. PMID- 29566706 TI - Dexmedetomidine attenuates lung apoptosis induced by renal ischemia-reperfusion injury through alpha2AR/PI3K/Akt pathway. AB - BACKGROUND: Acute lung injury caused by renal ischemia-reperfusion is one of the leading causes of acute kidney injury-related death. Dexmedetomidine, an alpha2 adrenergic agonist sedative, has been found to have protective effects against acute kidney injury and remote lung injury. We sought to determine whether dexmedetomidine can exert its anti-apoptotic effects in acute lung injury after acute kidney injury, in addition to its common anti-inflammatory effects, and to determine the underlying mechanisms. METHODS: In vivo, acute kidney injury was induced by 60 min of kidney ischemia (bilateral occlusion of renal pedicles) followed by 24 h of reperfusion. Mice received dexmedetomidine (25 ug/kg, i.p.) in the absence or presence of alpha2-adrenergic antagonist atipamezole (250 ug/kg, i.p.) before IR. Histological assessment of the lung was conducted by HE staining and arterial blood gases were measured. Lung apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay. The expression of caspase 3 and p-Akt in lung tissue was detected by western blot. In vitro, C57BL/6J mice pulmonary microvascular endothelial cells were treated with serum from mice obtained following sham or IR. Dexmedetomidine was given before serum stimulation in cells, alone or with atipamezole or LY294002. Cell viability was assessed by CCK 8 assay. Cell apoptosis was examined by Hoechst staining and Annexin V-FITC/PI staining flow cytometry analysis. Mitochondrial membrane potential was measured by flow cytometry. The expression of p-Akt, caspase 3, Bcl 2 and Bax was measured by western blot. RESULTS: In vivo, dexmedetomidine remarkably mitigated pathohistological changes and apoptosis and significantly increased p-Akt expression in the lung. In addition, dexmedetomidine also slightly improved oxygenation in mice after IR, which can be abolished by atipamezole. In vitro, dexmedetomidine significantly inhibited IR serum-induced loss of viability and apoptosis in PMVECs. Dexmedetomidine increased p-Akt in a time- and dose-dependent manner, and down-regulated the expression of caspase 3 and Bax and up-regulated the Bcl-2 expression in PMVECs. The changes of MMP were also improved by dexmedetomidine. Whilst these effects were abolished by Atipamezole or LY294002. CONCLUSION: Our results demonstrated that dexmedetomidine attenuates lung apoptosis induced by IR, at least in part, via alpha2AR/PI3K/Akt pathway. PMID- 29566707 TI - Impact of hypoglycemic episodes on health-related quality of life of type-2 diabetes mellitus patients: development and validation of a specific QoLHYPO(c) questionnaire. AB - BACKGROUND: Hypoglycemia is a limiting factor to achieving optimal glycemic control in patients with type-2 diabetes mellitus (T2DM), increasing risk of death and complications, reducing health-related quality of life (HRQoL) and work productivity and increasing healthcare costs. The study's primary objective was to develop and validate a specific questionnaire to assess the impact of hypoglycemia on the HRQoL of T2DM patients (QoLHYPO(c) questionnaire). METHODS: A two-phase multicenter prospective, longitudinal, observational, epidemiologic study of consecutively enrolled patients, not involving any drug, was conducted: In phase 1 (questionnaire development), patients who had given their written informed consent, who were at least 30 years of age, had been diagnosed with T2DM at least 5 years prior, had an HbA1c test in the previous 3 months, and a hypoglycemic episode in the previous 6 months were included. To validate the questionnaire and assess reliability and responsiveness, phase 2 included two cohorts of patients. Patients in the reliability cohort would likely have stable clinical course during the 3 weeks following inclusion in the study and patients in the responsiveness cohort would likely experience changes in their clinical course in the 3 months after enrollment. RESULTS: Phase 1 included 168 patients: 10 attended semi-structured interviews, 18 for face validity, and 140 for the pilot test (Rasch analysis). Phase 2 included 227 patients: 142 in the reliability cohort and 85 in the responsiveness cohort. Of the 37 items initially included in Phase 1, 11 (floor/ceiling effect analysis) and 13 (Rasch analysis) were discarded. The final version of the questionnaire consisted of 13 items. Phase 2 results showed the questionnaire was unidimensional and able to accurately assess HRQoL. Intra-observer reproducibility (ICC = 0.920) and internal consistency (Cronbach's alpha: visit 1 = 0.912; visit 2 = 0.901) were high, showing high reliability. Internal responsiveness was moderate (standardized effect size 0.5-0.8) and external responsiveness was lower (AUC > 0.5; not statistically significant). Minimal clinically important difference (MCID) was estimated to be 3.2 points. CONCLUSIONS: The QoLHYPO(c) questionnaire is a tool that can be used in routine clinical practice to assess the impact of hypoglycemia on the HRQoL of T2DM patients. PMID- 29566708 TI - Seizures in children with neurofibromatosis type 1: is neurofibromatosis type 1 enough? AB - BACKGROUND: Neurofibromatosis type 1 (NF1) is related to a generally increased prevalence of seizures. The mechanism underlying the increased predisposition to seizures has not been fully elucidated. The aim of the study was to evaluate the role of NF1 in seizures pathogenesis in a cohort of children with NF1 and seizures. METHODS: The medical records of 437 children (0-18 years old) with NF1 were reviewed. All children with at least one afebrile seizure were included. Demographic, clinical, neurological, NF1 mutation status, and EEG data were collected along with brain magnetic resonance imaging. Depending on etiology, structural seizures have been identified and were further classified as NF1 related or not. RESULTS: Nineteen patients (4.3%; 13 males) were included. NF1 was inherited in 7 (37.5%), with 3 maternal forms. Ten children with structural seizures were identified. Seven forms were identified someway related to NF1, two of which were associated to 17q11.2 microdeletion and hypoxic-ischemic encephalopathy. Any brain lesion that could explain seizures was found in nine patients, two third of these patients had a familiar history of epilepsy. CONCLUSIONS: Our results suggest seizures are more frequent in NF1 children (4.3%) than in general pediatric population (0.3-0.5%) and that are someway related to NF1 in half of patients. Facing seizures in NF1, the clinician should first exclude brain tumors but also other, and rarer NF1-related scenarios, such as hydrocephalous and vasculopathies. Children with non-structural seizures frequently had a family history of epilepsy, raising questions about the pathogenic role of NF1. They should be approached as for the general population. PMID- 29566709 TI - Cultural significance of the flora of a tropical dry forest in the Doche vereda (Villavieja, Huila, Colombia). AB - BACKGROUND: In Colombia, ethnobotanical studies regarding plant cultural significance (CS) in tropical dry forests are scarce and mainly focused on the Caribbean region. Different authors have indicated that the plants with the most uses are those of greater cultural importance. Additionally, gender differences in knowledge and interest in natural resources has been widely recorded. This study evaluated the cultural significance of plants in the Doche community, in the Department of Huila. Furthermore, it evaluates the richness of plant knowledge among local inhabitants, looking for testing the hypothesis that the CS of plants positively correlates to the number of uses people inform about, and that there are significant differences on the richness of ethnobotanical knowledge between men and women in this community. METHODS: The ethnobotanical categories: "food," "condiment," "economy," "fodder," "firewood," "timber", "medicine," and "others" were established to carry out semi-structured interviews, social cartography, and ethnobotanical walks. The frequency of mention was calculated as a measure of CS. The richness of knowledge of each collaborator was obtained. Non-parametric tests were performed to determine whether differences between the numbers of mentioned species existed between genders and ethnobotanical categories. Finally, Pearson correlation tests determined the relationship between CS and the number of ethnobotanical categories. RESULTS: A hundred useful species were registered in crops and forests. The most abundant categories were medicinal (45 species), firewood (30), and fodder (28). The most culturally significant species according to frequency of mention were Pseudosamanea guachapele, Guazuma ulmifolia, Manihot esculenta, and Musa balbisiana. The species with the most registered uses (five) were Guazuma ulmifolia and Gliricidia sepium. We found a correlation between CS and the number of uses per ethnobotanical category, but no significant difference between genders regarding ethnobotanical knowledge. CONCLUSION: Frequency of mention provides relevant information about the CS of species. Furthermore, it aids to establish sustainable use of tropical dry forests without loss of resources parting from strategies designed from within the Doche community and based on their ethnobotanical knowledge. We found that the number of uses of a plant is correlated with its degree of cultural importance. On the other hand, no significant differences were found between genders regarding ethnobotanical knowledge; that is, both men and women have similar roles in the community, which allows them to recognize the same uses per species. PMID- 29566710 TI - Assessment of user voluntary engagement during neurorehabilitation using functional near-infrared spectroscopy: a preliminary study. AB - BACKGROUND: Functional near infrared spectroscopy (fNIRS) finds extended applications in a variety of neuroscience fields. We investigated the potential of fNIRS to monitor voluntary engagement of users during neurorehabilitation, especially during combinatory exercise (CE) that simultaneously uses both, passive and active exercises. Although the CE approach can enhance neurorehabilitation outcome, compared to the conventional passive or active exercise strategies, the active engagement of patients in active motor movements during CE is not known. METHODS: We determined hemodynamic responses induced by passive exercise and CE to evaluate the active involvement of users during CEs using fNIRS. In this preliminary study, hemodynamic responses of eight healthy subjects during three different tasks (passive exercise alone, passive exercise with motor imagery, and passive exercise with active motor execution) were recorded. On obtaining statistically significant differences, we classified the hemodynamic responses induced by passive exercise and CEs to determine the identification accuracy of the voluntary engagement of users using fNIRS. RESULTS: Stronger and broader activation around the sensorimotor cortex was observed during CEs, compared to that during passive exercise. Moreover, pattern classification results revealed more than 80% accuracy. CONCLUSIONS: Our preliminary study demonstrated that fNIRS can be potentially used to assess the engagement of users of the combinatory neurorehabilitation strategy. PMID- 29566711 TI - Rising global burden of breast cancer: the case of sub-Saharan Africa (with emphasis on Nigeria) and implications for regional development: a review. AB - BACKGROUND: Despite mortality from breast cancer in Africa being higher than in high income countries, breast cancer has not been extensively studied in the region. The aim of this paper was to highlight the rising burden of breast cancer with an emphasis on sub-Saharan Africa as well as trends, characteristics, controversies and their implications for regional development. METHODOLOGY: A review of published studies and documents was conducted in Medline, Scopus, Pubmed and Google using combinations of key words-breast neoplasm, breast cancer, cancer, incidence, mortality, Africa, Nigeria. Graphical and frequency analyses were carried out on some of the incidence and mortality figures retrieved from published papers and the GLOBOCAN website. FINDINGS: Globally, about 25% and 15% of all new cancer cases and cancer deaths respectively among females were due to breast cancer. Africa currently had the highest age-standardized breast cancer mortality rate globally, with the highest incidence rates being recorded within the sub-Saharan African sub-region. Incidence trends such as inherently aggressive tumour and younger age profile had been subject to controversies. Certain factors such as westernized diet, urbanization and possibly increasing awareness had been implicated, though their specific contributions were yet to be fully established. CONCLUSION: Unless urgent action is taken, breast cancer will compound sub-Saharan Africa's disease burden, increase poverty and gender inequality as well as reverse the current global gains against maternal and neonatal mortality. PMID- 29566712 TI - The in vitro modulation of steroidogenesis by inflammatory cytokines and insulin in TM3 Leydig cells. AB - BACKGROUND: Cytokines and hormones, including insulin, are known to modulate the hypothalamic-pituitary-testes axis and steroidogenesis, both centrally and peripherally. In the context of chronic inflammation and hyperinsulinaemia mediating male hypogonadism associated with obesity, metabolic syndrome and type 2 diabetes mellitus, these mechanisms are poorly understood and the impact of cytokines and insulin on Leydig cell steroidogenesis has not been fully elicited. This study aimed to further investigate the in vitro impact of TNFalpha, IL1beta, IL6, IL8 and insulin on Leydig cell function and steroidogenesis. METHODS: hCG stimulated TM3 Leydig cells were exposed to various concentrations of TNFalpha, IL1beta, IL6, IL8 (100 ng/ml, 10 ng/ml, 1 ng/ml and 0.1 ng/ml) and insulin (10 ng/ml, 1 ng/ml, 0.1 ng/ml and 0.01 ng/ml) in optimal cell culture conditions over 48 h. Cell viability (XTT) and testosterone and progesterone concentrations (ELISA) were assessed using standardised laboratory techniques. RESULTS: TNFalpha significantly decreased cell viability and progesterone and testosterone concentrations in a dose-dependent relationship. IL1beta and IL6 had a subtle but significant negative effect on cell viability and testosterone concentrations, with a marked significant decrease in progesterone concentration at all concentrations investigated. IL8 showed an increase in cell viability, with no significant effect on testosterone concentrations alongside a significant decrease in progesterone concentrations. Insulin significantly increased cell viability and testosterone concentrations in a dose dependent relationship, but interestingly significantly decreased progesterone concentrations. CONCLUSIONS: The inflammatory cytokines TNFalpha, IL1beta and IL6 cause a dose dependent decline in steroidogenesis in TM3 Leydig cells. These results suggest that chronic inflammation may downregulate steroidogenesis in males via direct modulation of Leydig cell function. However, IL8 may stimulate TM3 Leydig cell growth. Insulin is associated with a dose-dependent increase in testosterone synthesis, with a significant decline in progesterone synthesis. With the phenomenon of insulin resistance, the literature is unclear on the potential role of hyperinsulinaemia in steroidogenesis. Further studies are warranted in order to fully elicit the molecular mechanisms and interactions of these molecules on male steroidogenesis. PMID- 29566713 TI - PHD-finger domain protein 5A functions as a novel oncoprotein in lung adenocarcinoma. AB - BACKGROUND: PHD-finger domain protein 5A (PHF5A) is a highly conserved small transcriptional regulator also involved in pre-mRNA splicing; however, its biological functions and molecular mechanisms in non-small cell lung cancer (NSCLC) have not yet been investigated. The purpose of this study was to determine the functional relevance and therapeutic potential of PHF5A in lung adenocarcinoma (LAC). METHODS: The expression of PHF5A in LAC tissues and adjacent non-tumor (ANT) tissues was investigated using immunohistochemistry of a tissue microarray, qRT-PCR, western blot and bioinformatics. The function of PHF5A was determined using several in vitro assays and also in vivo assay by lentiviral vector-mediated PHF5A depletion in LAC cell lines. RESULTS: PHF5A was highly upregulated in LAC tissues compared with the ANT counterparts, and closely associated with tumor progression and poor patient prognosis. These results were further confirmed by findings of the TCGA database. Moreover, functional studies demonstrated that PHF5A knockdown not only resulted in reduced cell proliferation, increased cell apoptosis, and cell cycle arrest, but also suppressed migration and invasion in LAC cells. PHF5A silencing was also found to inhibit LAC tumor growth in nude mice. Microarray and bioinformatics analyses revealed that PHF5A depletion led to dysregulation of multiple tumor signaling pathways; selected factors in key signaling pathways were verified in vitro. CONCLUSIONS: The data suggest for the first time that PHF5A is an oncoprotein that contributes to LAC progression by regulating multiple signaling pathways, and may constitute a prognostic factor and potential new therapeutic target in NSCLC. PMID- 29566714 TI - Stability in the feeding practices and styles of low-income mothers: questionnaire and observational analyses. AB - BACKGROUND: During the last two decades, researchers have devoted considerable attention to the role of maternal feeding behaviors, practices, and styles in the development of obesity in young children. Little is known, however, about the consistency of maternal feeding across settings and time. The purpose of this paper was to provide data on this issue by examining the consistency of observed maternal feeding behavior across multiple eating occasions, as well as examine the consistency of observed and self-reported maternal feeding behavior across 18 months. METHODS: Videotapes from two studies of low-income mothers and their preschool children were coded for feeding practices, dimensions, and styles: a study of 137 low-income, African American and Latina mothers and their children observed during three meals in their homes over a two to three week period, and a study of 138 low-income, Latina mothers observed during a buffet meal in a laboratory setting on two separate occasions 18 months apart. Videotapes from both studies were coded for a wide range of maternal feeding behaviors and strategies. Mothers in the second study also completed three validated, self report questionnaires on their feeding practices and styles. RESULTS: Overall, both observed and self-reported feeding practices and styles showed only moderate levels of stability across meals and over time. Maternal attempts to regulate children's eating showed more stability across meals and over time than the content of general mealtime conversation. Also, greater stability was found in what mothers were trying to get their children to do during the meals than in the strategies they used to influence child behavior. Self-reports of feeding showed greater stability over time than observational measures. Across meals and across 18 months, the stability of general feeding styles was between 40% and 50%. CONCLUSIONS: The findings demonstrate that maternal feeding behavior was only moderately stable across meals and over time-that is, feeding behavior varied considerably across situations. The lack of high levels of consistency in feeding behavior suggests that situational factors may play a major role in influencing maternal behavior as well. Family-focused childhood obesity programs should focus not only on helping parents change their feeding practices and styles, but also focus on increasing parents' sensitivity to situational factors that affect their approach to feeding their children. PMID- 29566715 TI - Neoadjuvant intraperitoneal chemotherapy followed by radical surgery and HIPEC in patients with very advanced gastric cancer and peritoneal metastases: report of an initial experience in a western single center. AB - BACKGROUND: The association of preoperative systemic and intraperitoneal chemotherapy has been described in Eastern patients with very good outcomes in treatment responders. The aim of this paper is to describe the initial results of this multidisciplinary regimen in gastric cancer patients with very advanced peritoneal metastases. CASE PRESENTATION: We present here the first four cases who received the treatment protocol. They had a baseline PCI between 19 and 33. Two patients had received systemic chemotherapy prior to this regimen. Three of them had significant response and were taken to cytoreductive surgery, while one patient who had 12 cycles of chemotherapy previously showed signs of disease progression and subsequently died. There was no significant postoperative morbidity, and three patients remain alive, two of them with no signs of recurrence. CONCLUSION: Systemic and intraperitoneal chemotherapy led to a marked response in peritoneal disease extent in our initial experience and allowed three of four patients with very advanced disease to be treated with cytoreductive surgery. PMID- 29566716 TI - Overexpression of zinc-alpha2-glycoprotein suppressed seizures and seizure related neuroflammation in pentylenetetrazol-kindled rats. AB - BACKGROUND: Zinc-alpha2-glycoprotein (ZAG) is a 42-kDa protein reported as an anti-inflammatory adipocytokine. Evidences from clinical and experimental studies revealed that brain inflammation plays important roles in epileptogenesis and seizure. Interestingly, closely relationship between ZAG and many important inflammatory mediators has been proven. Our previous study identified ZAG in neurons and found that ZAG is decreased in epilepsy and interacts with TGFbeta and ERK. This study aimed to investigate the role of ZAG in seizure and explore its effect on seizure-related neuroinflammation. METHODS: We overexpressed AZGP1 in the hippocampus of rats via adeno-associated virus vector injection and observed their seizure behavior and EEG after pentylenetetrazol (PTZ) kindling. The level of typical inflammation mediators including TNFalpha, IL-6, TGFbeta, ERK, and ERK phosphorylation were determined. RESULTS: The overexpression of AZGP1 reduced the seizure severity, prolonged the latency of kindling, and alleviated epileptiform discharges in EEG changes induced by PTZ. Overexpression of AZGP1 also suppressed the expression of TNFalpha, IL-6, TGFbeta, and ERK phosphorylaton in PTZ-kindled rats. CONCLUSIONS: ZAG may inhibit TGFbeta-mediated ERK phosphorylation and inhibit neuroinflammation mediated by TNFalpha and IL-6, suggesting ZAG may suppress seizure via inhibiting neuroinflammation. ZAG may be a potential and novel therapeutic target for epilepsy. PMID- 29566717 TI - Toward optimal implementation of cancer prevention and control programs in public health: a study protocol on mis-implementation. AB - BACKGROUND: Much of the cancer burden in the USA is preventable, through application of existing knowledge. State-level funders and public health practitioners are in ideal positions to affect programs and policies related to cancer control. Mis-implementation refers to ending effective programs and policies prematurely or continuing ineffective ones. Greater attention to mis implementation should lead to use of effective interventions and more efficient expenditure of resources, which in the long term, will lead to more positive cancer outcomes. METHODS: This is a three-phase study that takes a comprehensive approach, leading to the elucidation of tactics for addressing mis implementation. Phase 1: We assess the extent to which mis-implementation is occurring among state cancer control programs in public health. This initial phase will involve a survey of 800 practitioners representing all states. The programs represented will span the full continuum of cancer control, from primary prevention to survivorship. Phase 2: Using data from phase 1 to identify organizations in which mis-implementation is particularly high or low, the team will conduct eight comparative case studies to get a richer understanding of mis implementation and to understand contextual differences. These case studies will highlight lessons learned about mis-implementation and identify hypothesized drivers. Phase 3: Agent-based modeling will be used to identify dynamic interactions between individual capacity, organizational capacity, use of evidence, funding, and external factors driving mis-implementation. The team will then translate and disseminate findings from phases 1 to 3 to practitioners and practice-related stakeholders to support the reduction of mis-implementation. DISCUSSION: This study is innovative and significant because it will (1) be the first to refine and further develop reliable and valid measures of mis implementation of public health programs; (2) bring together a strong, transdisciplinary team with significant expertise in practice-based research; (3) use agent-based modeling to address cancer control implementation; and (4) use a participatory, evidence-based, stakeholder-driven approach that will identify key leverage points for addressing mis-implementation among state public health programs. This research is expected to provide replicable computational simulation models that can identify leverage points and public health system dynamics to reduce mis-implementation in cancer control and may be of interest to other health areas. PMID- 29566718 TI - Effect of a live attenuated vaccine against Lawsonia intracellularis in weaned and finishing pig settings in Finland. AB - BACKGROUND: The intracellular bacterium Lawsonia intracellularis is an important pathogen in modern swine production. The aim of this study was to investigate the effect of a live attenuated L. intracellularis vaccine (Enterisol Ileitis(r)) on the health and production parameters of weaned and finishing pigs in a commercial Finnish 850-sow farm with diagnosed L. intracellularis infection. The herd was free from enzootic pneumonia, swine dysentery, progressive atrophic rhinitis, sarcoptic mange and salmonellosis. Four weekly groups of approximately 500 piglets were included in the study for a total of approximately 2000 piglets. Half of these piglets were vaccinated at 3 weeks of age and the other half served as controls. The study piglets were ear-tagged with individual numbers and colour coded and were individually weighed at weaning (4 weeks), delivery to the finishing farm (12-14 weeks) and at slaughter. Mortality, symptoms of diseases and medications of the study piglets were registered in the nursery and finishing unit. Feed conversion rate was calculated for the finishing period and lean meat percentage was measured at slaughter. RESULTS: Vaccinated piglets had a higher live weight than unvaccinated piglets at delivery to the finishing unit (+ 1.18 kg, P = 0.002) and at slaughter (+ 3.57 kg, P < 0.001). The daily weight gain of vaccinated piglets was better than unvaccinated piglets in the nursery (+ 14.8 g/d, P = 0.013) and in the finishing unit (+ 30.9 g/d, P < 0.001). Vaccination had no effect on feed conversion rate or lean meat percentage (P = 0.102). Altogether, 3.9 and 4.6% of the pigs were medicated for different reasons in the vaccinated and control groups, respectively. The return on investment for the vaccination was calculated to be 0.41. CONCLUSIONS: Immunisation of piglets with a live attenuated L. intracellularis vaccine resulted in higher meat yield in pig production via significantly higher live weight and average daily weight gain in a Finnish specific pathogen-free setting. PMID- 29566719 TI - Functionalized rare earth-doped nanoparticles for breast cancer nanodiagnostic using fluorescence and CT imaging. AB - BACKGROUND: Breast cancer is the second leading cause of cancer death among women and represents 14% of death in women around the world. The standard diagnosis method for breast tumor is mammography, which is often related with false negative results leading to therapeutic delays and contributing indirectly to the development of metastasis. Therefore, the development of new tools that can detect breast cancer is an urgent need to reduce mortality in women. Here, we have developed Gd2O3:Eu3+ nanoparticles functionalized with folic acid (FA), for breast cancer detection. RESULTS: Gd2O3:Eu3+ nanoparticles were synthesized by sucrose assisted combustion synthesis and functionalized with FA using EDC-NHS coupling. The FA-conjugated Gd2O3:Eu3+ nanoparticles exhibit strong red emission at 613 nm with a quantum yield of ~ 35%. In vitro cytotoxicity studies demonstrated that the nanoparticles had a negligible cytotoxic effect on normal 293T and T-47D breast cancer cells. Cellular uptake analysis showed significantly higher internalization of FA-conjugated RE nanoparticles into T-47D cells (Folr hi ) compared to MDA-MB-231 breast cancer cells (Folr lo ). In vivo confocal and CT imaging studies indicated that FA-conjugated Gd2O3:Eu3+ nanoparticles accumulated more efficiently in T-47D tumor xenograft compared to the MDA-MB-231 tumor. Moreover, we found that FA-conjugated Gd2O3:Eu3+ nanoparticles were well tolerated at high doses (300 mg/kg) in CD1 mice after an intravenous injection. Thus, FA-conjugated Gd2O3:Eu3+ nanoparticles have great potential to detect breast cancer. CONCLUSIONS: Our findings provide significant evidence that could permit the future clinical application of FA-conjugated Gd2O3:Eu3+ nanoparticles alone or in combination with the current detection methods to increase its sensitivity and precision. PMID- 29566720 TI - Recalibrating disparities in perceived and actual balance abilities in older adults: a mixed-methods evaluation of a novel exergaming intervention. AB - BACKGROUND: Published reports suggest a disparity between perceived and actual balance abilities, a trait associated with increased fall-risk in older adults. We investigate whether it is possible to 'recalibrate' these disparities using a novel gaming intervention. METHODS: We recruited 26 older adults for a 4-week intervention in which they participated in 8-sessions using a novel gaming intervention designed to provide explicit, augmented feedback related to postural control. Measures of perceived balance abilities (Falls Efficacy Scale International) and actual postural control (limits of stability) were assessed pre- and post-intervention. We used focus groups to elicit the opinions of participants about how the game may have influenced balance abilities and confidence. RESULTS: A stronger alignment was observed between postural control and perceived balance capabilities post-intervention (i.e., significant correlations between Falls Efficacy Scale-International scores and limits of stability which were not present pre-intervention). Also, significant improvements in measures of postural control were observed, with these improvements confined to the aspects of postural control for which the exergame provided explicit, augmented feedback. Qualitative data revealed that the intervention made participants more "aware" of their balance abilities. CONCLUSIONS: Our results demonstrate that it is possible to recalibrate the perceptions of older adults relating to their balance abilities through a targeted, short-term intervention. We propose that the post-intervention improvements in postural control may have been, in part, the result of this recalibration; with altered perceptions leading to changes in balance performance. Findings support the application of novel interventions aimed at addressing the psychological factors associated with elderly falls. PMID- 29566721 TI - Barriers for conducting clinical trials in developing countries- a systematic review. AB - BACKGROUND: Clinical trials for identification of efficient and effective new diagnostic and treatment modalities are needed to address disproportionately high burden of communicable (e.g., HIV/AIDS, tuberculosis, and malaria) and non communicable diseases (e.g., diabetes) in developing countries. However, gross under-representation in global clinical trial platforms contributes to sustained health inequity in these countries. We reviewed the literature on barriers facing clinical researchers in developing countries for conducting clinical trials in their countries. METHODS: Literature indexed in PubMed, Embase, CINAHL and Web of Science, WHO Global Health Library were searched. Grey literature was also searched. Search key words included barriers, challenges, clinical trials and developing countries. Articles within the scope of this review were appraised by two reviewers. RESULTS: Ten studies, which are reported in 15 papers, were included in this review. Following critical review we identified five unifying themes for barriers. Barriers for conducting clinical trials included lack of financial and human capacity, ethical and regulatory system obstacles, lack of research environment, operational barriers and competing demands. CONCLUSION AND RECOMMENDATION: There were substantial barriers at system, organization and individual level. We propose that to address this problem, instituting a system for wider implementation of local investigator-initiated trials is warranted. These trials are more applicable to local populations because they build on local healthcare knowledge. They are more demand-led, influence policy and responsive to a country's needs because they are driven by a local or national agenda. PMID- 29566722 TI - Growth differentiation factor 15 contributes to marrow adipocyte remodeling in response to the growth of leukemic cells. AB - BACKGROUND: The adipocyte remodeling, including of the morphological change, might indicate special pathological function. Our previous study found that the morphological remodeling of larger marrow adipocytes into small marrow adipocytes correlates with a poor prognosis for acute myeloid leukemia (AML) patients. However, the mechanisms contributed to the marrow adipocyte remodeling are still poorly understood. METHODS: GDF15 expression was analyzed by RT-qPCR and western blotting assays in the leukemic cells. The enhancing and antibody neutralization tests in vitro were employed to evaluate the effect of GDF15 on the morphology of mature adipocytes. CCK8 test was used to detect the proliferation of leukemic cells after co-cultivation with small marrow adipocytes. Flow cytometry was used to analysis the proportion of cell cycle of leukemic cells. Immunofluorescence staining and linear analysis were applied to verify the GDF15 expression and the relationship between GDF15 and small marrow adipocytes in AML patients. RESULTS: In this study, we found that leukemic cell lines not only expressed significantly higher growth differentiation factor 15 (GDF15) than the other three cytokines associated with adipocyte differentiation in RNA level but also secreted GDF15 factor. Furthermore, the in vitro experiments demonstrated that GDF15 was involved in the conversion of small marrow adipocytes from larger marrow adipocytes. Correspondingly, the leukemic cells proliferated more rapidly through regulating the cell cycle when co-cultured with GDF15-induced small marrow adipocytes. The immunofluorescence staining on the bone marrow sections of AML patients further exhibited that GDF15 was partly produced by leukemic cells. The positive correlation between the concentration of GDF15 in the marrow aspirates and the number and the volume of small marrow adipocytes might suggest the contribution of GDF15 in AML patients (r = 0.72, r = 0.67). CONCLUSIONS: GDF15 secreted by leukemic cells was involved in the morphological remodeling of marrow adipocytes, which can in turn promote leukemic cell growth, indicating that GDF15 may be a promising treatment target for AML patients. PMID- 29566723 TI - Relationships between work outcomes, work attitudes and work environments of health support workers in Ontario long-term care and home and community care settings. AB - BACKGROUND: Our overarching study objective is to further our understanding of the work psychology of Health Support Workers (HSWs) in long-term care and home and community care settings in Ontario, Canada. Specifically, we seek novel insights about the relationships among aspects of these workers' work environments, their work attitudes, and work outcomes in the interests of informing the development of human resource programs to enhance elder care. METHODS: We conducted a path analysis of data collected via a survey administered to a convenience sample of Ontario HSWs engaged in the delivery of elder care over July-August 2015. RESULTS: HSWs' work outcomes, including intent to stay, organizational citizenship behaviors, and performance, are directly and significantly related to their work attitudes, including job satisfaction, work engagement, and affective organizational commitment. These in turn are related to how HSWs perceive their work environments including their quality of work life (QWL), their perceptions of supervisor support, and their perceptions of workplace safety. CONCLUSIONS: HSWs' work environments are within the power of managers to modify. Our analysis suggests that QWL, perceptions of supervisor support, and perceptions of workplace safety present particularly promising means by which to influence HSWs' work attitudes and work outcomes. Furthermore, even modest changes to some aspects of the work environment stand to precipitate a cascade of positive effects on work outcomes through work attitudes. PMID- 29566724 TI - Utilization of prevention of mother-to-child transmission (PMTCT) services among pregnant women in HIV care in Uganda: a 24-month cohort of women from pre conception to post-delivery. AB - OBJECTIVE: We assessed the uptake of prevention of mother-to-child transmission (PMTCT) services in a cohort of HIV infected women in care at The AIDS Support Organization Jinja and Kampala in Uganda, who were trying to conceive, over a period of 24 months, to inform the strengthening of PMTCT service access for women in care. RESULTS: Of the 299 women 127 (42.5%) reported at least one pregnancy within 24 months; 61 women (48.0%) delivered a live child. Of the 55 who had a live birth at the first pregnancy, 54 (98.2%) used antenatal care (ANC) starting at 15.5 weeks of gestation on average and 47/49 (95.9%) delivered at a health facility. Excluding miscarriages, 54 (98.2%) received ARVs during pregnancy. Of the 49 live births with post-delivery data, 37 (75.5%) tested the infant for HIV. 79 of the 127 (68.7%) spoke with providers about childbearing. Communication with providers was associated with ANC use (65.8% vs. 41.7%; p = .015). Despite the high rate of miscarriages and late ANC start, this study shows very high uptake of PMTCT services among PLHIV in care and their infants. Improved provider-client communication could enhance ANC attendance and PMTCT outcomes among HIV infected women in care. PMID- 29566725 TI - Interleukin-37 is increased in adult-onset Still's disease and associated with disease activity. AB - BACKGROUND: Interleukin (IL)-37 has been known to play an immunosuppressive role in various inflammatory disorders, but whether it participates in the regulation of pathogenesis of adult-onset Still's disease (AOSD) has not been investigated. In this study, we examined serum IL-37 levels and their clinical association with AOSD, and we explored the anti-inflammatory effects of IL-37 on peripheral blood mononuclear cells (PBMCs) from patients with AOSD. METHODS: Blood samples were collected from 62 patients with AOSD and 50 healthy control subjects (HC). The serum IL-37 levels were determined using an enzyme-linked immunosorbent assay (ELISA). The correlations of serum IL-37 levels with disease activity, laboratory values, and inflammatory cytokines in AOSD were analyzed by Spearman's correlation test. The correlations between serum IL-37 levels and clinical manifestations were analyzed by Mann-Whitney U test. PBMCs from ten patients with AOSD were stimulated with recombinant human IL-37 protein, and expression levels of tumor necrosis factor (TNF)-alpha, IL-6, IL-10, IL-1beta, and IL-18 were determined by qRT-PCR and ELISA. RESULTS: A significantly higher IL-37 protein level was observed in patients with AOSD than in HC. Serum IL-37 levels correlated with systemic score, laboratory values, IL-1beta, IL-18, and IL-10 in patients with AOSD. The expression levels of IL-37 were closely related to the patients with AOSD who also had fever, skin rash, lymphadenopathy, splenomegaly, myalgia, and arthralgia. Moreover, the production of proinflammatory cytokines such as IL-6, IL-1beta, TNF-alpha, and IL-18 in PBMCs from patients with AOSD was obviously attenuated after recombinant human IL-37 stimulation. CONCLUSIONS: Increased expression of IL-37 and its positive correlation with disease activity suggest its involvement in AOSD pathogenesis. More importantly, IL-37 inhibits the expression of proinflammatory cytokines in PBMCs from patients with AOSD, indicating the potential anti-inflammatory role of IL-37 in AOSD. Thus, IL-37 may be a novel disease activity biomarker and research target in AOSD. PMID- 29566727 TI - Myocellular characteristics in rheumatoid arthritis and osteoarthritis patients. PMID- 29566726 TI - Increased circulating resistin levels in early-onset breast cancer patients of normal body mass index correlate with lymph node negative involvement and longer disease free survival: a multi-center POSH cohort serum proteomics study. AB - BACKGROUND: Early-onset breast cancer (EOBC) affects about one in 300 women aged 40 years or younger and is associated with worse outcomes than later onset breast cancer. This study explored novel serum proteins as surrogate markers of prognosis in patients with EOBC. METHODS: Serum samples from EOBC patients (stages 1-3) were analysed using agnostic high-precision quantitative proteomics. Patients received anthracycline-based chemotherapy. The discovery cohort (n = 399) either had more than 5-year disease-free survival (DFS) (good outcome group, n = 203) or DFS of less than 2 years (poor outcome group, n = 196). Expressed proteins were assessed for differential expression between the two groups. Bioinformatics pathway and network analysis in combination with literature research were used to determine clinically relevant proteins. ELISA analysis against an independent sample set from the Prospective study of Outcomes in Sporadic versus Hereditary breast cancer (POSH) cohort (n = 181) was used to validate expression levels of the selected target. Linear and generalized linear modelling was applied to determine the effect of target markers, body mass index (BMI), lymph node involvement (LN), oestrogen receptor (ER), progesterone receptor and human epidermal growth factor receptor 2 status on patients' outcome. RESULTS: A total of 5346 unique proteins were analysed (peptide FDR p <= 0.05). Of these, 812 were differentially expressed in the good vs poor outcome groups and showed significant enrichment for the insulin signalling (p = 0.01) and the glycolysis/gluconeogenesis (p = 0.01) pathways. These proteins further correlated with interaction networks involving glucose and fatty acid metabolism. A consistent nodal protein to these metabolic networks was resistin (upregulated in the good outcome group, p = 0.009). ELISA validation demonstrated resistin to be upregulated in the good outcome group (p = 0.04), irrespective of BMI and ER status. LN involvement was the only covariate with a significant association with resistin measurements (p = 0.004). An ancillary in-silico observation was the induction of the inflammatory response, leucocyte infiltration, lymphocyte migration and recruitment of phagocytes (p < 0.0001, z-score > 2). Survival analysis showed that resistin overexpression was associated with improved DFS. CONCLUSIONS: Higher circulating resistin correlated with node-negative patients and longer DFS independent of BMI and ER status in women with EOBC. Overexpression of serum resistin in EOBC may be a surrogate indicator of improved prognosis. PMID- 29566729 TI - Intrauterine resuscitation during the second stage of term labour by maternal hyperoxygenation versus conventional care: study protocol for a randomised controlled trial (INTEREST O2). AB - BACKGROUND: Perinatal asphyxia is, even in developed countries, one the major causes of neonatal morbidity and mortality. Therefore, if foetal distress during labour is suspected, one should try to restore foetal oxygen levels or aim for immediate delivery. However, studies on the effect of intrauterine resuscitation during labour are scarce. We designed a randomised controlled trial to investigate the effect of maternal hyperoxygenation on the foetal condition. In this study, maternal hyperoxygenation is induced for the treatment of foetal distress during the second stage of term labour. METHODS/DESIGN: This study is a single-centre randomised controlled trial being performed in a tertiary hospital in The Netherlands. From among cases of a suboptimal or abnormal foetal heart rate pattern during the second stage of term labour, a total of 116 patients will be randomised to the control group, where normal care is provided, or to the intervention group, where before normal care 100% oxygen is supplied to the mother by a non-rebreathing mask until delivery. The primary outcome is change in foetal heart rate pattern. Secondary outcomes are Apgar score, mode of delivery, admission to the neonatal intensive care unit and maternal side effects. In addition, blood gas values and malondialdehyde are determined in umbilical cord blood. DISCUSSION: This study will be the first randomised controlled trial to investigate the effect of maternal hyperoxygenation for foetal distress during labour. This intervention should be recommended only as a treatment for intrapartum foetal distress, when improvement of the foetal condition is likely and outweighs maternal and neonatal side effects.

PMID- 29566728 TI - The association of mammographic density with risk of contralateral breast cancer and change in density with treatment in the WECARE study. AB - BACKGROUND: Mammographic density (MD) is an established predictor of risk of a first breast cancer, but the relationship of MD to contralateral breast cancer (CBC) risk is not clear, including the roles of age, mammogram timing, and change with treatment. Multivariable prediction models for CBC risk are needed and MD could contribute to these. METHODS: We conducted a case-control study of MD and CBC risk in phase II of the WECARE study where cases had a CBC diagnosed >= 2 years after first diagnosis at age <55 years and controls had unilateral breast cancer (UBC) with similar follow-up time. We retrieved film mammograms of the unaffected breast from two time points, prior to/at the time of the first diagnosis (253 CBC cases, 269 UBC controls) and >= 6 months up to 48 months following the first diagnosis (333 CBC cases, 377 UBC controls). Mammograms were digitized and percent MD (%MD) was measured using the thresholding program Cumulus. Odds ratios (OR) and 95% confidence intervals (CI) for association between %MD and CBC, adjusted for age, treatment, and other factors related to CBC, were estimated using logistic regression. Linear regression was used to estimate the association between treatment modality and change in %MD in 467 women with mammograms at both time points. RESULTS: For %MD assessed following diagnosis, there was a statistically significant trend of increasing CBC with increasing %MD (p = 0.03). Lower density (<25%) was associated with reduced risk of CBC compared to 25 to < 50% density (OR 0.69, 95% CI 0.49, 0.98). Similar, but weaker, associations were noted for %MD measurements prior to/at diagnosis. The relationship appeared strongest in women aged < 45 years and non-existent in women aged 50 to 54 years. A decrease of >= 10% in %MD between first and second mammogram was associated marginally with reduced risk of CBC (OR 0.63, 95% CI 0.40, 1.01) compared to change of <10%. Both tamoxifen and chemotherapy were associated with statistically significant 3% decreases in %MD (p < 0.01). CONCLUSIONS: Post-diagnosis measures of %MD may be useful to include in CBC risk prediction models with consideration of age at diagnosis. Chemotherapy is associated with reductions in %MD, similar to tamoxifen. PMID- 29566731 TI - Deep vein thrombosis and pulmonary embolism secondary to urinary retention: a case report. AB - BACKGROUND: Pulmonary embolism occurs when a blood thrombus forms and travels from a vein in the body to an artery in the lung. Thrombi often develop in one of the deep veins of the legs, thighs, or pelvis, a condition known as deep vein thrombosis. In this report, we describe a rare instance of a patient who developed deep vein thrombosis and pulmonary embolism secondary to urinary retention, and we also review some of the literature. CASE PRESENTATION: A 75 year-old Japanese man visited our hospital with the complaint of lower extremity weakness. A physical examination revealed bilateral leg edema. Contrast-enhanced computed tomography showed thrombi in both the bilateral intrapelvic veins and the right pulmonary artery, with an extremely distended bladder. We diagnosed deep vein thrombosis and pulmonary embolism due to urinary retention, which was attributed to detrusor insufficiency owing to both taking an anticholinergic drug and neurogenic bladder. The patient was immediately started on both management of voiding dysfunction and anticoagulant therapy. CONCLUSIONS: We encountered a patient with deep vein thrombosis and pulmonary embolism secondary to urinary retention that could have been fatal. In such cases, clinicians should always take into account appropriate management of voiding dysfunction. PMID- 29566730 TI - Collaborative care for the detection and management of depression among adults with hypertension in South Africa: study protocol for the PRIME-SA randomised controlled trial. AB - BACKGROUND: The high co-morbidity of mental disorders, particularly depression, with non-communicable diseases (NCDs) such as cardiovascular disease (CVD), is concerning given the rising burden of NCDs globally, and the role depression plays in confounding prevention and treatment of NCDs. The objective of this randomised control trial (RCT) is to determine the real-world effectiveness of strengthened depression identification and management on depression outcomes in hypertensive patients attending primary health care (PHC) facilities in South Africa (SA). METHODS/DESIGN: The study design is a pragmatic, two-arm, parallel cluster RCT, the unit of randomisation being the clinics, with outcomes being measured for individual participants. The 20 largest eligible clinics from one district in the North West Province are enrolled in the trial. Equal numbers of hypertensive patients (n = 50) identified as having depression using the Patient Health Questionnaire (PHQ-9) are enrolled from each clinic, making up a total of 1000 participants with 500 in each arm. The nurse clinicians in the control facilities receive the standard training in Primary Care 101 (PC101), a clinical decision support tool for integrated chronic care that includes guidelines for hypertension and depression care. Referral pathways available include referrals to PHC physicians, clinical or counselling psychologists and outpatient psychiatric and psychological services. In the intervention clinics, this training is supplemented with strengthened training in the depression components of PC101 as well as training in clinical communication skills for nurse-led chronic care. Referral pathways are strengthened through the introduction of a facility-based behavioural health counsellor, trained to provide structured manualised counselling for depression and adherence counselling for all chronic conditions. The primary outcome is defined as at least 50% reduction in PHQ-9 score measured at 6 months. DISCUSSION: This trial should provide evidence of the real world effectiveness of strengtheneddepression identification and collaborative management on health outcomes of hypertensive patients withcomorbid depression attending PHC facilities in South Africa.

PMID- 29566732 TI - Multiple-level stakeholder engagement in malaria clinical trials: addressing the challenges of conducting clinical research in resource-limited settings. AB - BACKGROUND: Multinational clinical trials are logistically complex and require close coordination between various stakeholders. They must comply with global clinical standards and are accountable to multiple regulatory and ethical bodies. In resource-limited settings, it is challenging to understand how to apply global clinical standards to international, national, and local factors in clinical trials, making multiple-level stakeholder engagement an important element in the successful conduct of these clinical trials. MAIN BODY: During the planning and implementation of a large multinational clinical trial for intermittent preventive treatment of malaria in pregnancy in resource-limited areas of sub Saharan Africa, we encountered numerous challenges, which required implementation of a range of engagement measures to ensure compliance with global clinical and regulatory standards. These challenges included coordination with ongoing global malaria efforts, heterogeneity in national regulatory structures, sub-optimal healthcare infrastructure, local practices and beliefs, and perspectives that view healthcare providers with undue trust or suspicion. In addition to engagement with international bodies, such as the World Health Organization, the Malaria in Pregnancy Consortium, the Steve Biko Centre for Bioethics, and the London School of Hygiene and Tropical Medicine, in order to address the challenges just described, Pfizer Inc. and Medicines for Malaria Venture (the "Sponsoring Entities" for these studies) and investigators liaised with national- and district-level stakeholders such as health ministers and regional/local community health workers. Community engagement measures undertaken by investigators included local meetings with community leaders to explain the research aims and answer questions and concerns voiced by the community. The investigators also engaged with family members of prospective trial participants in order to be sensitive to local practices and beliefs. CONCLUSION: Engagement with key stakeholders at international and national levels enabled the Sponsoring Entities to address challenges by aligning the study design with the requirements of health and regulatory agencies and to understand and address healthcare infrastructure needs prior to trial initiation. Local stakeholder engagement, including community members, study participants, and family enabled the investigators to address challenges by ensuring that study design and conduct were adapted to local considerations and ensuring accurate information about the study aims was shared with the public.

AB - CRISPR/dCas9 binds precisely to defined genomic sequences through targeting of guide RNA (gRNA) sequences. In vivo imaging of genomic loci can be achieved by recruiting fluorescent proteins using either dCas9 or gRNA. We thoroughly validate and compare the effectiveness and specificity of several dCas9/gRNA genome labeling systems. Surprisingly, we discover that in the gRNA-labeling strategies, accumulation of tagged gRNA transcripts leads to non-specific labeling foci. Furthermore, we develop novel bimolecular fluorescence complementation (BIFC) methods that combine the advantages of both dCas9-labeling and gRNA-labeling strategies. The BIFC-dCas9/gRNA methods demonstrate high signal to-noise ratios and have no non-specific foci.

AB - BACKGROUND: Published methods for quantification of magnetic resonance imaging (MRI) evidence of inflammation in the sacroiliac joint lack validation in pediatric populations. We evaluated the reliability and construct validity of the Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint inflammation score (SIS) in children with suspected or confirmed juvenile spondyloarthritis (JSpA). METHODS: The SPARCC SIS measures the presence, depth, and intensity of bone marrow inflammation on MRI through the cartilaginous part of the joint. Six readers blinded to clinical details except age, participated in two reading exercises, each preceded by a calibration exercise. Inter-observer reliability was assessed using intraclass correlation coefficients (ICCs) and for pre-specified acceptable reliability the inraclass correlation coefficient (ICC) was > 0.8. RESULTS: The SPARCC SIS had face validity and was feasible to score in pediatric cases in both reading exercises. Cases were mostly male (64%) and the median age at the time of imaging was 14.9 years. After calibration, the median ICC across all readers for the SIS total score was 0.81 (IQR 0.71-0.89). SPARCC SIS had weak correlation with disease activity (DA) as measured by the JSpADA (r = - 0.12) but discriminated significantly between those with and without elevated C-reactive protein (p = 0.03). CONCLUSION: The SPARCC SIS was feasible to score and had acceptable reliability in children. The ICC improved with additional calibration and reading exercises, for both experienced and inexperienced readers. PMID- 29566734 TI - Acute exacerbation of idiopathic pulmonary fibrosis: lessons learned from acute respiratory distress syndrome? AB - Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease characterized by progressive loss of lung function and poor prognosis. The so-called acute exacerbation of IPF (AE-IPF) may lead to severe hypoxemia requiring mechanical ventilation in the intensive care unit (ICU). AE-IPF shares several pathophysiological features with acute respiratory distress syndrome (ARDS), a very severe condition commonly treated in this setting.A review of the literature has been conducted to underline similarities and differences in the management of patients with AE-IPF and ARDS.During AE-IPF, diffuse alveolar damage and massive loss of aeration occurs, similar to what is observed in patients with ARDS. Differently from ARDS, no studies have yet concluded on the optimal ventilatory strategy and management in AE-IPF patients admitted to the ICU. Notwithstanding, a protective ventilation strategy with low tidal volume and low driving pressure could be recommended similarly to ARDS. The beneficial effect of high levels of positive end-expiratory pressure and prone positioning has still to be elucidated in AE-IPF patients, as well as the precise role of other types of respiratory assistance (e.g., extracorporeal membrane oxygenation) or innovative therapies (e.g., polymyxin-B direct hemoperfusion). The use of systemic drugs such as steroids or immunosuppressive agents in AE-IPF is controversial and potentially associated with an increased risk of serious adverse reactions.Common pathophysiological abnormalities and similar clinical needs suggest translating to AE-IPF the lessons learned from the management of ARDS patients. Studies focused on specific therapeutic strategies during AE-IPF are warranted. PMID- 29566736 TI - Impact of diuretics on the urate lowering therapy in patients with gout: analysis of an inception cohort. AB - BACKGROUND: Diuretics have been associated with impaired response and refractoriness in gout, but whether this effect is still present with new urate lowering drugs (ULD) and treat-to-target strategies is unknown. The aim of the present study was to assess the impact of the diuretics on the response to ULD in patients with gout. METHODS: This was a retrospective analysis of an inception cohort. Participants were classified according to the type of ULD prescribed. We analysed the maximal dose of ULD (primary outcome variable), serum urate (SU) reduction, and the achievement of different SU targets (6 mg/dL, 5 mg/dL, and 4 mg/dL), according to the type of ULD prescribed and use of diuretics (loop and/or thiazide). We adjusted for confounders using multiple linear regression analysis. RESULTS: We included 245 patients: 208 treated with allopurinol (66 on diuretics, 31.7%), 35 with febuxostat (19 on diuretics, 57.6%), and 2 with benzbromarone. Significantly fewer participants in the allopurinol plus diuretics subgroup achieved SU levels of less than 5 mg/dL, but we found no other significant differences in SU targets associated with diuretics. Regarding the maximum ULD dose, a simple linear regression suggested an inverse relationship with diuretics (beta = - 0.125, p = 0.073), but this did not hold in the multivariable analysis (beta = - 0.47, p = 0.833). There was no association with febuxostat (beta = - 0.116, p = 0.514). CONCLUSION: Diuretics do not appear to have a significant impact on managing gout. PMID- 29566737 TI - Murine breast cancer feed arteries are thin-walled with reduced alpha1A adrenoceptor expression and attenuated sympathetic vasocontraction. AB - BACKGROUND: Perfusion of breast cancer tissue limits oxygen availability and metabolism but angiogenesis inhibitors have hitherto been unsuccessful for breast cancer therapy. In order to identify abnormalities and possible therapeutic targets in mature cancer arteries, we here characterize the structure and function of cancer feed arteries and corresponding control arteries from female FVB/N mice with ErbB2-induced breast cancer. METHODS: We investigated the contractile function of breast cancer feed arteries and matched control arteries by isometric myography and evaluated membrane potentials and intracellular [Ca2+] using sharp electrodes and fluorescence microscopy, respectively. Arterial wall structure is assessed by transmission light microscopy of arteries mounted in wire myographs and by evaluation of histological sections using the unbiased stereological disector technique. We determined the expression of messenger RNA by reverse transcription and quantitative polymerase chain reaction and studied receptor expression by confocal microscopy of arteries labelled with the BODIPY tagged alpha1-adrenoceptor antagonist prazosin. RESULTS: Breast cancer feed arteries are thin-walled and produce lower tension than control arteries of similar diameter in response to norepinephrine, thromboxane-analog U46619, endothelin-1, and depolarization with elevated [K+]. Fewer layers of similarly sized vascular smooth muscle cells explain the reduced media thickness of breast cancer arteries. Evidenced by lower media stress, norepinephrine-induced and thromboxane-induced tension development of breast cancer arteries is reduced more than is explained by the thinner media. Conversely, media stress during stimulation with endothelin-1 and elevated [K+] is similar between breast cancer and control arteries. Correspondingly, vascular smooth muscle cell depolarizations and intracellular Ca2+ responses are attenuated in breast cancer feed arteries during norepinephrine but not during endothelin-1 stimulation. Protein expression of alpha1-adrenoceptors and messenger RNA levels for alpha1A adrenoceptors are lower in breast cancer arteries than control arteries. Sympathetic vasocontraction elicited by electrical field stimulation is inhibited by alpha1-adrenoceptor blockade and reduced in breast cancer feed arteries compared to control arteries. CONCLUSION: Thinner media and lower alpha1 adrenoceptor expression weaken contractions of breast cancer feed arteries in response to sympathetic activity. We propose that abnormalities in breast cancer arteries can be exploited to modify tumor perfusion and thereby either starve cancer cells or facilitate drug and oxygen delivery during chemotherapy or radiotherapy. PMID- 29566738 TI - Fecal microbiota transplantation against intestinal colonization by extended spectrum beta-lactamase producing Enterobacteriaceae: a proof of principle study. AB - OBJECTIVE: Infections with multidrug-resistant microorganisms are associated with increased hospitalization, medication costs and mortality. Based on our fecal microbiota transplantation (FMT) experience for Clostridium difficile infection, we treated 15 patients carrying ESBL-producing Enterobacteriaceae (ESBL-EB) with FMT. Seven patients underwent a second FMT after 4 weeks when ESBL-EB remained, amounting to a total number of 22 transplants. The objective was decolonization of ESBL-EB. RESULTS: Three out of fifteen (20%) patients were ESBL-negative at 1, 2 and 4 weeks after the first transplant, while six out of 15 (40%) were negative after the second transplant. Comparison of fecal microbiota at baseline and 4 weeks after FMT revealed restoration of microbial diversity after FMT and a microbial shift towards donor composition. Finally, we suggest several possible factors of response to therapy, such as donor-recipient microbiota match and number of FMTs. Therefore, FMT can be an effective treatment in patients carrying ESBL-EB. Response may be determined by microbiota composition and number of FMT procedures.

PMID- 29566740 TI - Effect of filgotinib, a selective JAK 1 inhibitor, with and without methotrexate in patients with rheumatoid arthritis: patient-reported outcomes. AB - BACKGROUND: The aim was to assess patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) treated with filgotinib during two phase 2b, 24 week, randomized, placebo-controlled studies. METHODS: Patients with moderate-to severe active RA and an inadequate response to methotrexate (MTX) were randomized to daily placebo or filgotinib 50 mg, 100 mg, or 200 mg as add-on therapy to MTX (NCT01888874) or as monotherapy (NCT01894516). At week 12, nonresponders receiving filgotinib 50 mg in both studies or placebo in the add-on study, and all patients receiving placebo as monotherapy, were re-assigned to filgotinib 100 mg. PROs were measured using the Health Assessment Questionnaire - Disability Index (HAQ-DI) including Patient Pain assessed by visual analog scale, and the Patient Global Assessment of Disease Activity (Patient Global), the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale (Version 4), and the 36-Item Short Form Health Survey (SF-36). RESULTS: At week 12, improvements in all PROs, apart from the SF-36 mental component in the add-on study, were statistically better with filgotinib than placebo; some improvements were noted as early as the first assessment time point (week 1 or week 4). Filgotinib improved HAQ-DI by 0.58-0.84 points, FACIT-Fatigue by 6.9-11.4 points, Patient Global by 25.2-35.6 mm, and Pain by 24.2-37.9 mm; scores were maintained or improved to week 24. Across all PROs, more patients achieved minimal clinically important differences and normative values with filgotinib 200 mg than placebo. Patients re-assigned to filgotinib 100 mg at week 12 experienced improvements in PROs between weeks 12 to 24. CONCLUSIONS: Filgotinib as MTX add-on therapy or as monotherapy demonstrated rapid and sustained (to 24 weeks) improvements in health related quality of life and functional status in patients with active RA.

PMID- 29566739 TI - Collaborative care for the detection and management of depression among adults receiving antiretroviral therapy in South Africa: study protocol for the CobALT randomised controlled trial. AB - BACKGROUND: The scale-up of antiretroviral treatment (ART) programmes has seen HIV/AIDS transition to a chronic condition characterised by high rates of comorbidity with tuberculosis, non-communicable diseases (NCDs) and mental health disorders. Depression is one such disorder that is associated with higher rates of non-adherence, progression to AIDS and greater mortality. Detection and treatment of comorbid depression is critical to achieve viral load suppression in more than 90% of those on ART and is in line with the recent 90-90-90 Joint United Nations Programme on HIV/AIDS (UNAIDS) targets. The CobALT trial aims to provide evidence on the effectiveness and cost-effectiveness of scalable interventions to reduce the treatment gap posed by the growing burden of depression among adults on lifelong ART. METHODS: The study design is a pragmatic, parallel group, stratified, cluster randomised trial in 40 clinics across two rural districts of the North West Province of South Africa. The unit of randomisation is the clinic, with outcomes measured among 2000 patients on ART who screen positive for depression using the Patient Health Questionnaire (PHQ 9). Control group clinics are implementing the South African Department of Health's Integrated Clinical Services Management model, which aims to reduce fragmentation of care in the context of rising multimorbidity, and which includes training in the Primary Care 101 (PC101) guide covering communicable diseases, NCDs, women's health and mental disorders. In intervention clinics, we supplemented this with training specifically in the mental health components of PC101 and clinical communications skills training to support nurse-led chronic care. We strengthened the referral pathways through the introduction of a clinic based behavioural health counsellor equipped to provide manualised depression counselling (eight sessions, individual or group), as well as adherence counselling sessions (one session, individual). The co-primary patient outcomes are a reduction in PHQ-9 scores of at least 50% from baseline and viral load suppression rates measured at 6 and 12 months, respectively. DISCUSSION: The trial will provide real-world effectiveness of case detection and collaborative care for depression including facility-based counselling on the mental and physical outcomes for people on lifelong ART in resource-constrained settings.

PMID- 29566741 TI - The amino acid transporter SLC7A5 confers a poor prognosis in the highly proliferative breast cancer subtypes and is a key therapeutic target in luminal B tumours. AB - BACKGROUND: Breast cancer (BC) is a heterogeneous disease characterised by variant biology and patient outcome. The amino acid transporter, SLC7A5, plays a role in BC although its impact on patient outcome in different BC subtypes remains to be validated. This study aimed to determine whether the clinicopathological and prognostic value of SLC7A5 is different within the molecular classes of BC. METHODS: SLC7A5 was assessed at the genomic level, using Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) data (n = 1980), and proteomic level, using immunohistochemical analysis and tissue microarray (TMA) (n = 2664; 1110 training and 1554 validation sets) in well characterised primary BC cohorts. SLC7A5 expression correlated with clinicopathological and biological parameters, molecular subtypes and patient outcome. RESULTS: SLC7A5 mRNA and protein expression were strongly correlated with larger tumour size and higher grade. High expression was observed in triple negative (TN), human epidermal growth factor receptor 2 (HER2)+, and luminal B subtypes. SLC7A5 mRNA and protein expression was significantly associated with the expression of the key regulator of tumour cell metabolism, c-MYC, specifically in luminal B tumours only (p = 0.001). High expression of SLC7A5 mRNA and protein was associated with poor patient outcome (p < 0.001) but only in the highly proliferative oestrogen receptor (ER)+/ luminal B (p = 0.007) and HER2+ classes of BC (p = 0.03). In multivariate analysis, SLC7A5 protein was an independent risk factor for shorter breast-cancer-specific survival only in ER+ high-proliferation tumours (p = 0.02). CONCLUSIONS: SLC7A5 appears to play a role in the aggressive highly proliferative ER+ subtype driven by MYC and could act as a potential therapeutic target. Functional assessment is necessary to reveal the specific role played by this transporter in the ER+ highly proliferative subclass and HER2+ subclass of BC. PMID- 29566742 TI - Smoking is not linked to the development of anti-peptidylarginine deiminase 4 autoantibodies in rheumatoid arthritis. AB - BACKGROUND: Defining environmental factors responsible for development of autoimmunity in rheumatoid arthritis (RA) is critical for understanding mechanisms of disease initiation and propagation. Notably, a history of cigarette smoking has been implicated in the genesis of RA and is associated with worse disease outcomes. Antibodies to peptidylarginine deiminase 4 (PAD4) are also associated with more severe RA. A subset of patients who have PAD4 autoantibodies that cross-react with PAD3 (anti-PAD3/4) are at the highest risk for interstitial lung disease, and this risk is augmented by a history of cigarette smoking. It is unclear, however, if smoking is etiologically linked to the development of anti PAD4 antibodies. METHODS: Patients were included in this study if they had physician-diagnosed RA as well as DNA, serum, and a date-matched clinical assessment (n = 274). Anti-PAD4 and anti-CCP antibodies were measured by immunoprecipitation and ELISA, respectively; shared epitope (SE) status was determined by HLA-DRbeta1 genotyping. Logistic regression analysis was used to evaluate associations of smoking with PAD4 antibodies, with adjustment for relevant demographic and clinical features. Stratified analyses by disease duration and shared epitope status were also performed. RESULTS: Anti-PAD4 antibodies were present in 25% of RA patients, with 50% of these individuals having anti-PAD3/4 cross-reactive antibodies. Anti-PAD4 antibodies were significantly associated with a longer disease duration, SE alleles, and anti-CCP antibodies. Importantly, there were no significant differences in smoking history between anti-PAD4 positive and negative groups in univariate analyses, stratified analyses, or multivariable models. However, an inverse relationship between smoking and anti-PAD4 antibodies was suggested by a lower prevalence of current smokers among patients with anti-PAD3/4 antibodies compared to antibody negative individuals (p = 0.04). Further, the lowest levels of anti-PAD4 antibodies were observed in current smokers (p = 0.14), and a significant association of SE and anti-PAD4 antibodies was only present among never smokers (p = 0.01). CONCLUSIONS: Smoking history was not associated with anti-PAD4 antibodies in patients with RA. The finding that anti-PAD4 antibodies were not associated with smoking suggests that other environmental factors may contribute to the development of autoimmunity to PAD4 in these patients. PMID- 29566743 TI - Electronic cigarettes use and perception amongst medical students: a cross sectional survey from Sindh, Pakistan. AB - OBJECTIVE: The manufacturers of electronic cigarettes (e-cigarettes) are actively marketing their product through electronic and social media. Undergraduate medical students are expected to have better knowledge and awareness as they directly interact with patients in their training, The purpose of this study is therefore, to determine knowledge, use and perception regarding e-cigarettes among medical students from Sindh, Pakistan. RESULTS: A cross-sectional study was conducted between 1st July and 30th September 2016 at five different medical colleges situated in the second largest province of Sindh, Pakistan. The data was collected through a structured, self-administered questionnaire. Of the 500 students, the mean age was 21.5 +/- 1.7 years and 58% were females. Over (65.6%) students were aware of e-cigarettes, 31 (6.2%) reported having used e-cigarettes, of whom 6 (1.2%) self-reported daily use. Users of conventional tobacco products were significantly more likely to have heard of e-cigarettes (87.6% vs 51.6%, p < 0.001) and having used them (13.9% vs 1.3%, p < 0.001). On multivariable logistic regression analysis we found a strong association of e-cigarette use with consumption of conventional cigarettes [OR: 10.6, 95% CI 3.6-30.8, p < 0.001], use of smokeless tobacco products [OR: 7.9, 95% CI 2.7-23.4, p < 0.001] however a weak association was observed for Shisha use [OR: 3.05, 95% CI 0.9-9.6, p = 0.05]. PMID- 29566744 TI - Exercise combined with Acceptance and Commitment Therapy (ExACT) compared to a supervised exercise programme for adults with chronic pain: study protocol for a randomised controlled trial. AB - BACKGROUND: Acceptance and Commitment Therapy (ACT) is a form of cognitive behavioural therapy, which may be beneficial for people with chronic pain. The approach aims to enhance daily functioning through increased psychological flexibility. Whilst the therapeutic model behind ACT appears well suited to chronic pain, there is a need for further research to test its effectiveness in clinical practice, particularly with regards to combining ACT with physical exercise. METHODS/DESIGN: This prospective, two-armed, parallel-group, single centre randomised controlled trial (RCT) will assess the effectiveness of a combined Exercise and ACT programme, in comparison to supervised exercise for chronic pain. One hundred and sixty patients, aged 18 years and over, who have been diagnosed with a chronic pain condition by a physician will be recruited to the trial. Participants will be individually randomised to one of two 8-week, group interventions. The combined group will take part in weekly psychology sessions based on the ACT approach, in addition to supervised exercise classes led by a physiotherapist. The control group will attend weekly supervised exercise classes but will not take part in an ACT programme. The primary outcome will be pain interference at 12-week follow-up, measured using the Brief Pain Inventory-Interference Scale. Secondary outcomes will include self-reported pain severity, self-perception of change, patient satisfaction, quality of life, depression, anxiety and healthcare utilisation. Treatment process measures will include self-efficacy, pain catastrophising, fear avoidance, pain acceptance and committed action. Physical activity will be measured using Fitbit ZipTM activity trackers. Both groups will be followed up post intervention and again after 12 weeks. Estimates of treatment effects at follow-up will be based on an intention to-treat framework, implemented using a linear mixed-effects model. Individual and focus group qualitative interviews will be undertaken with a purposeful sample of participants to explore patient experiences of both treatments. DISCUSSION: To our knowledge, this will be the first RCT to examine whether combining exercise with ACT produces greater benefit for patients with chronic pain, compared to a standalone supervised exercise programme.

PMID- 29566745 TI - Antibodies against chemokine receptors CXCR3 and CXCR4 predict progressive deterioration of lung function in patients with systemic sclerosis. AB - BACKGROUND: The chemokine receptors CXCR3 and CXCR4 are involved in the pathogenesis of fibrosis, a key feature of systemic sclerosis (SSc). It is hypothesized that immunoglobulin (Ig)G antibodies (abs) against these two receptors are present in patients with SSc and are associated with clinical findings. METHODS: Anti-CXCR3 and anti-CXCR4 ab levels were measured in 449 sera from 327 SSc patients and in 234 sera from healthy donors (HD) by enzyme-linked immunosorbent assay (ELISA). In SSc, ab levels were compared with clinical data in a cross-sectional and longitudinal setting. Protein expression of CXCR3 and CXCR4 on peripheral blood mononuclear cells (PBMCs) was analyzed in 17 SSc patients and 8 HD by flow cytometry. RESULTS: Anti-CXCR3 and anti-CXCR4 ab levels were different among SSc subgroups compared with HD and were highest in diffuse SSc patients. The ab levels strongly correlated with each other (r = 0.85). Patients with SSc-related interstitial lung disease (SSc-ILD) exhibited higher ab levels which negatively correlated with lung function parameters (e.g., r = -0.5 and r = -0.43 for predicted vital capacity, respectively). However, patients with deterioration of lung function showed lower anti-CXCR3/4 ab levels compared with those with stable disease. Frequencies and median fluorescence intensities (MFI) of CXCR3+ and CXCR4+ PBMCs were lower in SSc patients compared with HD and correlated with the severity of skin and lung fibrosis. They correlated with the severity of skin and lung fibrosis. CONCLUSIONS: Anti-CXCR3/4 abs and their corresponding receptors are linked with the severity of SSc-ILD. Antibody levels discriminate patients with stable or decreasing lung function and could be used for risk stratification.

AB - OBJECTIVE: A recent meta-analysis surmised pedometers were a useful panacea to independently reduce sedentary time (ST). To further test and expand on this deduction, we analyzed the ability of a consumer-wearable activity tracker to reduce ST and prolonged sedentary bouts (PSB). We originally conducted a 12-month randomized control trial where 800 employees from 13 organizations were assigned to control, activity tracker, or one of two activity tracker plus incentive groups designed to increase step count. The primary outcome was accelerometer measured moderate-to-vigorous physical activity. RESULTS: We conducted a secondary analysis on accelerometer measured daily ST and PSB bouts. A general linear mixed model was used to examine changes in ST and prolonged sedentary bouts, followed by between-group pairwise comparisons. Regression analyses were conducted to examine the association of changes in step counts with ST and PSB. The changes in ST and PSB were not statistically significant and not different between the groups (P < 0.05). Increases in step counts were concomitantly associated with decreases in ST and PSB, regardless of intervention (P < 0.05). Caution should be taken when considering consumer-wearable activity trackers as a means to reduce sedentary behavior. Trial registration NCT01855776 Registered: August 8, 2012.

PMID- 29566748 TI - High salt diet exacerbates colitis in mice by decreasing Lactobacillus levels and butyrate production. AB - BACKGROUND: Changes in hygiene and dietary habits, including increased consumption of foods high in fat, simple sugars, and salt that are known to impact the composition and function of the intestinal microbiota, may explain the increase in prevalence of chronic inflammatory diseases. High salt consumption has been shown to worsen autoimmune encephalomyelitis and colitis in mouse models through p38/MAPK signaling pathway. However, the effect of high salt diet (HSD) on gut microbiota and on intestinal immune homeostasis, and their roles in determining vulnerability to intestinal inflammatory stimuli are unknown. Here, we investigate the role of gut microbiota alterations induced by HSD on the severity of murine experimental colitis. RESULTS: Compared to control diet, HSD altered fecal microbiota composition and function, reducing Lactobacillus sp. relative abundance and butyrate production. Moreover, HSD affected the colonic, and to a lesser extent small intestine mucosal immunity by enhancing the expression of pro-inflammatory genes such as Rac1, Map2k1, Map2k6, Atf2, while suppressing many cytokine and chemokine genes, such as Ccl3, Ccl4, Cxcl2, Cxcr4, Ccr7. Conventionally raised mice fed with HSD developed more severe DSS- (dextran sodium sulfate) and DNBS- (dinitrobenzene sulfonic acid) induced colitis compared to mice on control diet, and this effect was absent in germ-free mice. Transfer experiments into germ-free mice indicated that the HSD-associated microbiota profile is critically dependent on continued exposure to dietary salt. CONCLUSIONS: Our results indicate that the exacerbation of colitis induced by HSD is associated with reduction in Lactobacillus sp. and protective short-chain fatty acid production, as well as changes in host immune status. We hypothesize that these changes alter gut immune homeostasis and lead to increased vulnerability to inflammatory insults.

AB - Merkel Cell carcinoma (MCC) is a rare but aggressive cancer, with an estimated disease-associated mortality as high as 46%. MCC has proven to be an immunologically responsive disease and the advent of immune checkpoint inhibitors has changed the treatment landscape for patients with advanced MCC. In this review, we discuss the rationale for the use of immune checkpoint inhibition, review current single agent therapies tested in and approved for MCC, and discuss emerging immunotherapeutic options for these patients. PMID- 29566750 TI - Predicting complications of major head and neck oncological surgery: an evaluation of the ACS NSQIP surgical risk calculator. AB - BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) universal surgical risk calculator is an online tool intended to improve the informed consent process and surgical decision making. The risk calculator uses a database of information from 585 hospitals to predict a patient's risk of developing specific postoperative outcomes. METHODS: Patient records at a major Canadian tertiary care referral center between July 2015 and March 2017 were reviewed for surgical cases including one of six major head and neck oncologic surgeries: total thyroidectomy, total laryngectomy, hemiglossectomy, partial glossectomy, laryngopharyngectomy, and composite resection. Preoperative information for 107 patients was entered into the risk calculator and compared to observed postoperative outcomes. Statistical analysis of the risk calculator was completed for the entire study population, for stratification by procedure, and by utilization of microvascular reconstruction. Accuracy was assessed using the ratio of predicted to observed outcomes, Receiver Operating Characteristics (ROC), Brier score, and the Wilcoxon signed-ranked test. RESULTS: The risk calculator accurately predicted the incidences for 11 of 12 outcomes for patients that did not undergo free flap reconstruction (NFF group), but was less accurate for patients that underwent free flap reconstruction (FF group). Length of stay (LOS) analysis showed similar results, with predicted and observed LOS statistically different in the overall population and FF group analyses (p = 0.001 for both), but not for the NFF group analysis (p = 0.764). All outcomes in the NFF group, when analyzed for calibration, met the threshold value (Brier scores < 0.09). Risk predictions for 8 of 12, and 10 of 12 outcomes were adequately calibrated in the FF group and the overall study population, respectively. Analyses by procedure were excellent, with the risk calculator showing adequate calibration for 7 of 8 procedural categories and adequate discrimination for all calculable categories (6 of 6). CONCLUSION: The NSQIP-RC demonstrated efficacy for predicting postoperative complications in head and neck oncology surgeries that do not require microvascular reconstruction. The predictive value of the metric can be improved by inclusion of several factors important for risk stratification in head and neck oncology. PMID- 29566751 TI - Engineering a multicellular vascular niche to model hematopoietic cell trafficking. AB - BACKGROUND: The marrow microenvironment and vasculature plays a critical role in regulating hematopoietic cell recruitment, residence, and maturation. Extensive in vitro and in vivo studies have aimed to understand the marrow cell types that contribute to hematopoiesis and the stem cell environment. Nonetheless, in vitro models are limited by a lack of complex multicellular interactions, and cellular interactions are not easily manipulated in vivo. Here, we develop an engineered human vascular marrow niche to examine the three-dimensional cell interactions that direct hematopoietic cell trafficking. METHODS: Using soft lithography and injection molding techniques, fully endothelialized vascular networks were fabricated in type I collagen matrix, and co-cultured under flow with embedded marrow fibroblast cells in the matrix. Marrow fibroblast (mesenchymal stem cells (MSCs), HS27a, or HS5) interactions with the endothelium were imaged via confocal microscopy and altered endothelial gene expression was analyzed with RT-PCR. Monocytes, hematopoietic progenitor cells, and leukemic cells were perfused through the network and their adhesion and migration was evaluated. RESULTS: HS27a cells and MSCs interact directly with the vessel wall more than HS5 cells, which are not seen to make contact with the endothelial cells. In both HS27a and HS5 co-cultures, endothelial expression of junctional markers was reduced. HS27a co-cultures promote perfused monocytes to adhere and migrate within the vessel network. Hematopoietic progenitors rely on monocyte-fibroblast crosstalk to facilitate preferential recruitment within HS27a co-cultured vessels. In contrast, leukemic cells sense fibroblast differences and are recruited preferentially to HS5 and HS27a co-cultures, but monocytes are able to block this sensitivity. CONCLUSIONS: We demonstrate the use of a microvascular platform that incorporates a tunable, multicellular composition to examine differences in hematopoietic cell trafficking. Differential recruitment of hematopoietic cell types to distinct fibroblast microenvironments highlights the complexity of cell cell interactions within the marrow. This system allows for step-wise incorporation of cellular components to reveal the dynamic spatial and temporal interactions between endothelial cells, marrow-derived fibroblasts, and hematopoietic cells that comprise the marrow vascular niche. Furthermore, this platform has potential for use in testing therapeutics and personalized medicine in both normal and disease contexts. PMID- 29566752 TI - Affect, risk perception, and the use of cigarettes and e-cigarettes: a population study of U.S. adults. AB - BACKGROUND: Tobacco companies argue that the decision to smoke is made by well informed rational adults who have considered all the risks and benefits of smoking. Yet in promoting their products, the tobacco industry frequently relies on affect, portraying their products as part of a desirable lifestyle. Research examining the roles of affect and perceived risks in smoking has been scant and non-existent for novel tobacco products, such as electronic cigarettes (e cigarettes). METHODS: We examined the relationship between affect, perceived risk, and current use for cigarettes and e-cigarettes in 2015 in a nationally representative sample of 5398 U.S. adults who were aware of e-cigarettes. RESULTS: Participants held various affective associations with tobacco products, and affect towards cigarettes was more negative than affect towards e-cigarettes. Using structural equation modeling (SEM), affect towards cigarettes and e cigarettes was associated with cigarette smoking and e-cigarette use respectively, and these associations were both direct and partially mediated by risk perceptions towards smoking and e-cigarette use. More positive affect towards cigarettes or e-cigarettes was associated with lower perceived risks, which in turn was associated with higher odds of being a current cigarette or e cigarette user. CONCLUSIONS: In developing models explaining tobacco use behavior, or in creating public communication campaigns aimed at curbing tobacco use, it is useful to focus not only on the reason based predictors, such as perceptions of risks and benefits, but also on affective predictors. Educational efforts aimed at further smoking reductions should highlight and reinforce negative images and associations with cigarettes. PMID- 29566753 TI - A physician targeted intervention improves prescribing in chronic heart failure in general medical units. AB - BACKGROUND: Despite strong evidence for beta-blockers and angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) in chronic heart failure (CHF), they have been under-utilised especially in general medical units. We aim to evaluate the effectiveness and feasibility of a physician-targeted quality improvement intervention with education and feedback on the prescription of beta-blockers and ACEI/ARB for CHF management in an inpatient setting. METHODS: We conducted an interrupted time series study between January 2009 and February 2012. A two-stage intervention was implemented. Between November 2009 and January 2011, a structured physician-oriented education program was undertaken. From February 2011, quarterly performance feedback was provided to each medical unit by a senior clinician. Medical notes of patients admitted with CHF under general medical units before and during the intervention were prospectively audited. Main outcomes were beta-blockers and ACEI/ARB prescription rates, and 180-day readmission rates for CHF. RESULTS: Four hundred and sixty eight patients were included in this study. Structured education program was associated with a significant rise in beta-blockers prescription rates from a baseline of 60 to 92% (p = 0.003), but a non-sustained rise in ACEI/ARB prescription. Regular performance feedback resulted in a further sustained increase in ACEI/ARB prescription rates from 62 to 93% (p = 0.028) and a positive trend for beta-blockers with rates maintained at 89%. There was a reduction in 180-day readmission rates that correlated with the improvements in beta-blocker (p = 0.030) and ACEI/ARB (p = 0.035) prescription. CONCLUSION: Implementation of a structured education program with regular performance feedback was durable and was associated with improvements in appropriate prescribing and an observed decrease in CHF-related readmissions. PMID- 29566754 TI - A qualitative study of community perception and acceptance of biological larviciding for malaria mosquito control in rural Burkina Faso. AB - BACKGROUND: Vector and malaria parasite's rising resistance against pyrethroid impregnated bed nets and antimalarial drugs highlight the need for additional control measures. Larviciding against malaria vectors is experiencing a renaissance with the availability of environmentally friendly and target species specific larvicides. In this study, we analyse the perception and acceptability of spraying surface water collections with the biological larvicide Bacillus thuringiensis israelensis in a single health district in Burkina Faso. METHODS: A total of 12 focus group discussions and 12 key informant interviews were performed in 10 rural villages provided with coverage of various larvicide treatments (all breeding sites treated, the most productive breeding sites treated, and untreated control). RESULTS: Respondents' knowledge about the major risk factors for malaria transmission was generally good. Most interviewees stated they performed personal protective measures against vector mosquitoes including the use of bed nets and sometimes mosquito coils and traditional repellents. The acceptance of larviciding in and around the villages was high and the majority of respondents reported a relief in mosquito nuisance and malarial episodes. There was high interest in the project and demand for future continuation. CONCLUSION: This study showed that larviciding interventions received positive resonance from the population. People showed a willingness to be involved and financially support the program. The positive environment with high acceptance for larviciding programs would facilitate routine implementation. An essential factor for the future success of such programs would be inclusion in regional or national malaria control guidelines. PMID- 29566755 TI - Conceptualisation and development of the Conversational Health Literacy Assessment Tool (CHAT). AB - BACKGROUND: The aim of this study was to develop a tool to support health workers' ability to identify patients' multidimensional health literacy strengths and challenges. The tool was intended to be suitable for administration in healthcare settings where health workers must identify health literacy priorities as the basis for person-centred care. METHODS: Development was based on a qualitative co-design process that used the Health Literacy Questionnaire (HLQ) as a framework to generate questions. Health workers were recruited to participate in an online consultation, a workshop, and two rounds of pilot testing. RESULTS: Participating health workers identified and refined ten questions that target five areas of assessment: supportive professional relationships, supportive personal relationships, health information access and comprehension, current health behaviours, and health promotion barriers and support. CONCLUSIONS: Preliminary evidence suggests that application of the Conversational Health Literacy Assessment Tool (CHAT) can support health workers to better understand the health literacy challenges and supportive resources of their patients. As an integrated clinical process, the CHAT can supplement existing intake and assessment procedures across healthcare settings to give insight into patients' circumstances so that decisions about care can be tailored to be more appropriate and effective. PMID- 29566756 TI - Vaginal health and hygiene practices and product use in Canada: a national cross sectional survey. AB - BACKGROUND: The vaginal microbiome influences quality of life and health. The composition of vaginal microbiota can be affected by various health behaviors, such as vaginal douching. The purpose of this study was to examine the types and prevalence of diverse vaginal/genital health and hygiene behaviors among participants living in Canada and to examine associations between behavioral practices and adverse gynecological health conditions. METHOD: An anonymous online survey, available in English and French, was distributed across Canada. The sample consisted of 1435 respondents, 18 years or older, living in Canada. RESULTS: Respondents reported engaging in diverse vaginal/genital health and hygiene behavioral practices, including the use of commercially manufactured products and homemade and naturopathic products and practices. Over 95% of respondents reported using at least one product in or around the vaginal area. Common products and practices included vaginal/genital moisturizers, anti-itch creams, feminine wipes, washes, suppositories, sprays, powders, and waxing and shaving pubic hair. The majority of the sample (80%) reported experiencing one or more adverse vaginal/genital symptom in their lifetime. Participants who had used any vaginal/genital product(s) had approximately three times higher odds of reporting an adverse health condition. Several notable associations between specific vaginal/genital health and hygiene products and adverse health conditions were identified. CONCLUSIONS: This study is the first of its kind to identify the range and prevalence of vaginal/genital health and hygiene behaviors in Canada. Despite a lack of credible information about the impact of these behaviors on women's health, the use of commercially manufactured and homemade products for vaginal/genital health and hygiene is common. Future research can extend the current exploratory study by identifying causal relationships between vaginal/genital health and hygiene behaviors and changes to the vaginal microbiome. PMID- 29566758 TI - Measurement and analysis of equity in health: a case study conducted in Zhejiang Province, China. AB - BACKGROUND: Equity is the core of primary care. The issue of equity in health has become urgent, and China has attached increasing attention to it. With rapid economic development and great changes in medical insurance policy, the pattern of equity in health has changed tremendously. The reform of healthcare in Zhejiang Province is at the forefront in China, and studies on Zhejiang Province are of great significance to the entire country. This paper aimed to measure health equity from the perspectives of health needs and health-seeking behavior and to provide suggestions for the next policy formulations, with respect to timeliness. METHODS: The investigator's household survey was conducted in August 2016. A sample of 1000 households, which included2807 individuals in Zhejiang, China, was obtained with the multi-stage stratified cluster sampling method. Descriptive analysis and chi-square tests were adopted in the analysis. The value of the concentration index was used to measure the equity. RESULTS: This study found that the poor have more urgent health needs and poorer health situations than the rich. Through studies on health-seeking behavior, the utilization of outpatient services was almost equitable, while the utilization of hospitalization showed a pro-rich inequity (i.e., the rich use more services). Individuals with employer-based medical insurance used more outpatient services than those with rural and urban medical insurance. More people in the poorer income groups did not use inpatient services due to financial difficulties. CONCLUSIONS: Absolute medical prices and medical insurance may explain the equity in the utilization of outpatient services and the inequity in the utilization of hospitalization. In view of the pro-rich inequity of hospitalization, more financial protection should be provided for the poor. PMID- 29566759 TI - Impairment of microcirculation and vascular responsiveness in adolescents with primary Raynaud phenomenon. AB - BACKGROUND: Raynaud's phenomenon (RP) is a functional vascular disease, presenting with recurrent episodes of ischemia of extremities in response to cold and emotional stress. Investigating cutaneous microcirculation is an important tool in understanding the complex neuro-immuno-vascular interactions in its pathophysiological mechanisms. Since there is no available data on vascular responsiveness in RP in the paediatric population, we investigated skin perfusion and heat-induced hyperaemia in comparison with clinical severity and laboratory parameters of the disease. METHODS: Fifty two adolescents (27 patients with primary RP and 25 age-matched healthy controls) were investigated in the study. Patients were divided into two groups according to the symptoms existing within the previous 2 months. Following baseline microcirculation measurement with Laser Doppler flowmetry (Periflux 5000 system), all subjects underwent local heating test at 42 degrees C and 44 degrees C. Besides routine laboratory parameters, immune-serological tests and the vasoactive sensory neuropeptides somatostatin and pituitary adenylate-cyclase activating polypeptide (PACAP) were measured. RESULTS: Baseline perfusion measured in perfusion units (PU) at 32 degrees C was significantly lower in symptomatic RP patients (97.6 +/- 22.4 PU) compared with both healthy volunteers (248.3 +/- 23.5 PU, p < 0.001) and RP patients without symptoms (187.4 +/- 24.9 PU, p < 0.05). After local heating to 42 degrees C maximum blood flow was significantly reduced in primary RP participants with current symptoms (358.6 +/- 43.9 PU, p < 0.001), but not in asymptomatic ones (482.3 +/- 28.7 PU, p > 0.05) when compared with healthy subjects (555.9 +/- 28.2 PU). Both the area under the response curve and the latency to reach the maximum flow were significantly increased in both RP groups (symptomatic 164.6 +/- 7.4 s, p < 0.001, asymptomatic 236.4 +/- 17.4 s, p < 0.001) when compared with the control group (101.9 +/- 4.7 s). The heat-induced percentage increase from baseline to maximal blood flow was significantly greater in symptomatic RP adolescents in comparison with healthy ones. Laboratory parameters and neuropeptide plasma levels were not altered in any groups. CONCLUSION: To our knowledge this is the first study in paediatric population to show altered heat induced cutaneous hyperaemia responses in relation with the clinical severity and symptomatology. PMID- 29566760 TI - Vascular biosafety of commercial hydroxyapatite particles: discrepancy between blood compatibility assays and endothelial cell behavior. AB - BACKGROUND: Vascular homeostasis is ensured by a dynamic interplay involving the endothelium, the platelets and the coagulation system. Thus, the vascular safety of particulate materials must address this integrated system, an approach that has been largely neglected. This work analysed the effects of commercial hydroxyapatite (HA) particles in blood compatibility and in endothelial cell behavior, due to their clinical relevance and scarcity of data on their vascular biosafety. RESULTS: Particles with similar chemical composition and distinct size and morphology were tested, i.e. rod-like, nano dimensions and low aspect ratio (HAp1) and needle-shape with wider size and aspect ratio (HAp2). HAp1 and HAp2, at 1 to 10 mg/mL, did not affect haemolysis, platelet adhesion, aggregation and activation, or the coagulation system (intrinsic and extrinsic pathways), although HAp2 exhibited a slight thrombogenic potential at 10 mg/mL. Notwithstanding, significantly lower levels presented dose-dependent toxicity on endothelial cells' behavior. HAp1 and HAp2 decreased cell viability at levels >= 250 and >= 50 MUg/mL, respectively. At 10 and 50 MUg/mL, HAp1 did not interfere with the F-actin cytoskeleton, apoptotic index, cell cycle progression, expression of vWF, VECad and CD31, and the ability to form a network of tubular like structures. Comparatively, HAp2 caused dose-dependent toxic effects in these parameters in the same concentration range. CONCLUSION: The most relevant observation is the great discrepancy of HA particles' levels that interfere with the routine blood compatibility assays and the endothelial cell behavior. Further, this difference was also found to be dependent on the particles' size, morphology and aspect ratio, emphasizing the need of a complementary biological characterization, taking into consideration the endothelial cells' functionality, to establish the vascular safety of particulate HA. PMID- 29566757 TI - Molecular mechanism of diabetic cardiomyopathy and modulation of microRNA function by synthetic oligonucleotides. AB - Diabetic cardiomyopathy (DCM) is a chronic complication in individuals with diabetes and is characterized by ventricular dilation and hypertrophy, diastolic dysfunction, decreased or preserved systolic function and reduced ejection fraction eventually resulting in heart failure. Despite being well characterized, the fundamental mechanisms leading to DCM are still elusive. Recent studies identified the involvement of small non-coding small RNA molecules such as microRNAs (miRs) playing a key role in the etiology of DCM. Therefore, miRs associated with DCM represents a new class of targets for the development of mechanistic therapeutics, which may yield marked benefits compared to other therapeutic approaches. Indeed, few miRs currently under active clinical investigation, with many expressing cautious optimism that miRs based therapies will succeed in the coming years. The major caution in using miRs based therapy is the need to improve the stability and specificity following systemic injection, which can be achieved through chemical and structural modification. In this review, we first discuss the established role of miRs in DCM and the advances in miRs based therapeutic strategies for the prevention/treatment of DCM. We next discuss the currently employed chemical modification of miR oligonucleotides and their utility in therapies specifically focusing on the DCM. Finally, we summarize the commonly used delivery system and approaches for assessment of miRNA modulation and potential off-target effects. PMID- 29566761 TI - The expression profile of human peripheral blood mononuclear cell miRNA is altered by antibody-dependent enhancement of infection with dengue virus serotype 3. AB - BACKGROUND: Antibody-dependent enhancement (ADE) of dengue virus (DENV) infection has been identified as the main risk factor for severe dengue disease, although the underlying mechanisms leading to severe dengue fever remain unclear. MicroRNAs (miRNAs) participate in numerous pathological and biological processes, including host responses to viral infections. METHOD: Here, we aimed to investigate the differences in miRNA expression patterns in human peripheral blood mononuclear cells (PBMCs) infected with DENV-3 and DENV-3-ADE at various time points employing high-throughput sequencing. RESULTS: According to miRNAs high-throughput sequencing, a total of 50 known miRNAs exhibited significant differences. GO (Gene Ontology) and pathway analysis of the predicted targets showed enrichment in the regulation of transcription, including multicellular organismal development, DNA-dependent transcription, negative regulation of cell differentiation and transcription. Afterwards, regulatory networks of miRNA predicted targets, miRNA transcription factors, miRNA pathways and miRNA GOs were formulated to expose the complex regulatory mechanisms of miRNAs during the infection phase. Finally, we analyzed hierarchical GO categories of the predicted targets involved in the MAPK signaling pathway, the cGMP-PKG signaling pathway, the cAMP signaling pathway, the endocytosis effect, and our analyses indicated that innate and adaptive immunity following DENV-3 and DENV-3-ADE infections may be signally distinct. CONCLUSION: Our results demonstrate a novel describing miRNA expression profiles in human PBMCs with DENV-3 and DENV-3-ADE infections using high-throughput sequencing. Our findings could provide a beneficial basis for further studies on the regulatory roles of miRNAs relevant to the different immune responses caused by DENV-3 and DENV-3-ADE infections.

PMID- 29566762 TI - Partial breast irradiation with CyberKnife after breast conserving surgery: a pilot study in early breast cancer. AB - BACKGROUND: Local recurrences after breast conserving treatment are mainly close to the original tumor site, and as such shorter fractionation strategies focused on and nearest mammary gland, i.e. accelerated partial breast irradiation (APBI), have been developed. Stereotactic APBI has been attempted, although there is little experience using CyberKnife (CK) for early breast cancer. METHODS: This pilot study was designed to assess the feasibility of CK-APBI on 20 evaluable patients of 29 eligible, followed for 2 years. The primary endpoint was acute/sub acute toxicity; secondary endpoints were late toxicity and the cosmetic result. RESULTS: Mean pathological tumor size was 10.5 mm (+/-4.3, range 3-18), 8 of these patients were classified as LumA-like, 11 as LumB-like, and 1 as LumB-HER2 enriched. Using CK-APBI with Iris, the treatment time was approximately 60 min (range~ 35 to ~ 120). All patients received 30 Gy in five fractions delivered to the PTV. The median number of beams was 180 (IQR 107-213; range:56-325) with a median PTV isodose prescription of 86.0% (IQR 85.0-88.5; range:82-94). The median PTV was 88.1 cm3 (IQR 63.8-108.6; range:32.3-238.8). The median breast V100 and V50 was 0.6 (IQR 0.1-1.5; range:0-13) and 18.6 (IQR 13.1-21.7; range:7.5-37), respectively. The median PTV minimum dose was 26.2 Gy (IQR 24.7-27.6; range 22.3 29.3). Mild side effects were recorded during the period of observation. Cosmetic evaluations were performed by three observers from the start of radiotherapy up to 2 years. Patients' evaluation progressively increase from 60% to 85% of excellent rating; this trend was similar to that of external observer. CONCLUSIONS: These preliminary results showed the safe feasibility of CK-APBI in early breast cancer, with mild acute and late toxicity and very good cosmetic results.

AB - Europe and North America have been leaders in rheumatology for many years. However, for more than a decade now the East Asian region has been catching up dramatically. Some aspects of rheumatology in East Asia are now almost comparable to those in the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR). In this article, we describe recent progress in rheumatology in East Asia, focusing specifically on Japan, Korea, and China. PMID- 29566766 TI - A customized home-based computerized cognitive rehabilitation platform for patients with chronic-stage stroke: study protocol for a randomized controlled trial. AB - BACKGROUND: Stroke patients usually suffer primary cognitive impairment related to attention, memory, and executive functions. This impairment causes a negative impact on the quality of life of patients and their families, and may be long term. Cognitive rehabilitation has been shown to be an effective way to treat cognitive impairment and should be continued after hospital discharge. Computerized cognitive rehabilitation can be performed at home using exercise programs that advance with predetermined course content, interval, and pace. We hypothesize that computerized rehabilitation might be improved if a program could customize course content and pace in response to patient-specific progress. The present pilot study is a randomized controlled double-blind crossover clinical trial aiming to study if chronic stroke patients with cognitive impairment could benefit from cognitive training through a customized tele-rehabilitation platform ("Guttmann, NeuroPersonalTrainer"(r), GNPT(r)). METHODS/DESIGN: Individuals with chronic-stage stroke will be recruited. Participants will be randomized to receive experimental intervention (customized tele-rehabilitation platform, GNPT(r)) or sham intervention (ictus.online), both with the same frequency and duration (five sessions per week over 6 weeks). After a washout period of 3 months, crossover will occur and participants from the GNPT(r) condition will receive sham intervention, while participants originally from the sham intervention will receive GNPT(r). Patients will be assessed before and after receiving each treatment regimen with an exhaustive neuropsychological battery. Primary outcomes will include rating measures that assess attention difficulties, memory failures, and executive dysfunction for daily activities, as well as performance-based measures of attention, memory, and executive functions. DISCUSSION: Customized cognitive training could lead to better cognitive function in patients with chronic-stage stroke and improve their quality of life. TRIAL REGISTRATION: NCT03326349 . Registered 31 October 2017. PMID- 29566767 TI - Methotrexate upregulates circadian transcriptional factors PAR bZIP to induce apoptosis on rheumatoid arthritis synovial fibroblasts. AB - BACKGROUND: Effects of methotrexate (MTX) on the proliferation of rheumatoid arthritis (RA) synovial fibroblasts are incompletely understood. We explored actions of MTX in view of circadian transcriptions of synovial fibroblasts. METHODS: Under treatment with MTX, expression of core circadian clock genes, circadian transcriptional factor proline and acidic amino acid-rich basic leucine zipper (PAR bZIP), and proapoptotic molecule Bcl-2 interacting killer (Bik) was examined by real-time polymerase chain reaction. Protein expression of circadian clock gene PERIOD2 (PER2) and CYTOCHROME C was also examined by western blotting and ELISA. Promoter activities of Per2 and Bik were measured by Luciferase assay. Expression of PER2, BIK, and CYTOCHROME C and morphological changes of the nucleus were observed by fluorescent immunostaining. Synovial fibroblasts were transfected with Per2/Bik small interfering RNA, and successively treated with MTX to determine cell viabilities. Finally, synovial fibroblasts were treated with MTX according to the oscillation of Per2/Bik expression. RESULTS: MTX (10 nM) significantly decreased cell viabilities, but increased messenger RNA expression of Per2, Bik, and PAR ZIP including D site of the albumin promoter binding protein (Dbp), hepatic leukemia factor (Hlf), and thyrotroph embryonic factor (Tef). MTX also increased protein expression of PER2 and CYTOCHROME C, and promoter activities of Per2 and Bik via D-box. Under fluorescent observations, expression of PER2, BIK, and CYTOCHROME C was increased in apoptotic cells. Cytotoxicity of MTX was attenuated by silencing of Per2 and/or Bik, and revealed that MTX was significantly effective in situations where Per2/Bik expression was high. CONCLUSIONS: We present here novel unique action of MTX on synovial fibroblasts that upregulates PAR bZIP to transcribe Per2 and Bik, resulting in apoptosis induction. MTX is important in modulating circadian environments to understand a new aspect of pathogenesis of RA. PMID- 29566769 TI - Effectiveness and safety of tofacitinib in rheumatoid arthritis: a cohort study. AB - BACKGROUND: Tofacitinib is the first oral Janus kinase inhibitor approved for the treatment of rheumatoid arthritis (RA). We compared the effectiveness and safety of tofacitinib, disease-modifying antirheumatic drugs (DMARDs), tumor necrosis factor inhibitors (TNFi), and non-TNF biologics in patients with RA previously treated with methotrexate. METHODS: We used MarketScan(r) databases (2011-2014) to study methotrexate-exposed patients with RA who were newly prescribed tofacitinib, DMARDs other than methotrexate, and biologics. The date of first prescription was defined as the cohort entry. The therapy was considered effective if all of the following criteria from a claims-based algorithm were achieved at the first year of follow-up: high adherence, no biologic or tofacitinib switch or addition, no DMARD switch or addition, no increase in dose or frequency of index drug, no more than one glucocorticoid joint injection, and no new/increased oral glucocorticoid dose. The safety outcome was serious infections requiring hospitalization. Non-TNF biologics comprised the reference group. RESULTS: We included 21,832 patients with RA, including 0.8% treated with tofacitinib, 24.7% treated with other DMARDs, 61.2% who had started therapy with TNFi, and 13.3% treated with non-TNF biologics. The rates of therapy effectiveness were 15.4% for tofacitinib, 11.1% for DMARDs, 18.6% for TNFi, and 19.8% for non-TNF biologics. In adjusted analyses, tofacitinib and non-TNF biologics appeared to have similar effectiveness rates, whereas DMARD initiators were less effective than non-TNF biologics. We could not clearly establish if tofacitinib was associated with a higher rate of serious infections. CONCLUSIONS: In patients with RA previously treated with methotrexate, our comparisons of tofacitinib with non-TNF biologics, though not definitive, did not demonstrate differences with respect to hospitalized infections or effectiveness. PMID- 29566768 TI - Functional genomics identifies specific vulnerabilities in PTEN-deficient breast cancer. AB - BACKGROUND: Phosphatase and tensin homolog (PTEN) is one of the most frequently inactivated tumor suppressors in breast cancer. While PTEN itself is not considered a druggable target, PTEN synthetic-sick or synthetic-lethal (PTEN-SSL) genes are potential drug targets in PTEN-deficient breast cancers. Therefore, with the aim of identifying potential targets for precision breast cancer therapy, we sought to discover PTEN-SSL genes present in a broad spectrum of breast cancers. METHODS: To discover broad-spectrum PTEN-SSL genes in breast cancer, we used a multi-step approach that started with (1) a genome-wide short interfering RNA (siRNA) screen of ~ 21,000 genes in a pair of isogenic human mammary epithelial cell lines, followed by (2) a short hairpin RNA (shRNA) screen of ~ 1200 genes focused on hits from the first screen in a panel of 11 breast cancer cell lines; we then determined reproducibility of hits by (3) identification of overlaps between our results and reanalyzed data from 3 independent gene-essentiality screens, and finally, for selected candidate PTEN SSL genes we (4) confirmed PTEN-SSL activity using either drug sensitivity experiments in a panel of 19 cell lines or mutual exclusivity analysis of publicly available pan-cancer somatic mutation data. RESULTS: The screens (steps 1 and 2) and the reproducibility analysis (step 3) identified six candidate broad spectrum PTEN-SSL genes (PIK3CB, ADAMTS20, AP1M2, HMMR, STK11, and NUAK1). PIK3CB was previously identified as PTEN-SSL, while the other five genes represent novel PTEN-SSL candidates. Confirmation studies (step 4) provided additional evidence that NUAK1 and STK11 have PTEN-SSL patterns of activity. Consistent with PTEN-SSL status, inhibition of the NUAK1 protein kinase by the small molecule drug HTH-01 015 selectively impaired viability in multiple PTEN-deficient breast cancer cell lines, while mutations affecting STK11 and PTEN were largely mutually exclusive across large pan-cancer data sets. CONCLUSIONS: Six genes showed PTEN-SSL patterns of activity in a large proportion of PTEN-deficient breast cancer cell lines and are potential specific vulnerabilities in PTEN-deficient breast cancer. Furthermore, the NUAK1 PTEN-SSL vulnerability identified by RNA interference techniques can be recapitulated and exploited using the small molecule kinase inhibitor HTH-01-015. Thus, NUAK1 inhibition may be an effective strategy for precision treatment of PTEN-deficient breast tumors. PMID- 29566770 TI - Stem cell properties of human clonal salivary gland stem cells are enhanced by three-dimensional priming culture in nanofibrous microwells. AB - BACKGROUND: Three-dimensional (3D) cultures recapitulate the microenvironment of tissue-resident stem cells and enable them to modulate their properties. We determined whether salivary gland-resident stem cells (SGSCs) are primed by a 3D spheroid culture prior to treating irradiation-induced salivary hypofunction using in-vitro coculture and in-vivo transplant models. METHODS: 3D spheroid derived SGSCs (SGSCs3D) were obtained from 3D culture in microwells consisting of a nanofiber bottom and cell-repellent hydrogel walls, and were examined for salivary stem or epithelial gene/protein expression, differentiation potential, and paracrine secretory function compared with monolayer-cultured SGSCs (SGSCs2D) in vitro and in vivo. RESULTS: SGSCs3D expressed increased salivary stem cell markers (LGR5 and THY1) and pluripotency markers (POU5F1 and NANOG) compared with SGSCs2D. Also, SGSCs3D exhibited enhanced potential to differentiate into salivary epithelial cells upon differentiation induction and increased paracrine secretion as compared to SGSCs2D. Wnt signaling was activated by 3D spheroid formation in the microwells and suppression of the Wnt/beta-catenin pathway led to reduced stemness of SGSCs3D. Enhanced radioprotective properties of SGSCs3D against radiation-induced salivary hypofunction was confirmed by an organotypic 3D coculture and in-vivo transplantation experiments. CONCLUSION: The 3D spheroid culture of SGSCs in nanofibrous microwells promotes stem cell properties via activation of Wnt signaling. This may contribute to SGSC priming prior to regenerative therapy to restore salivary hypofunction after radiotherapy. PMID- 29566771 TI - Microbiota inoculum composition affects holobiont assembly and host growth in Daphnia. AB - BACKGROUND: Host-associated microbiota is often acquired by horizontal transmission of microbes present in the environment. It is hypothesized that differences in the environmental pool of colonizers can influence microbiota community assembly on the host and as such affect holobiont composition and host fitness. To investigate this hypothesis, the host-associated microbiota of the invertebrate eco(toxico)logical model Daphnia was experimentally disturbed using different concentrations of the antibiotic oxytetracycline. The community assembly and host-microbiota interactions when Daphnia were colonized by the disturbed microbiota were investigated by inoculating germ-free individuals with the microbiota. RESULTS: Antibiotic-induced disturbance of the microbiota had a strong effect on the subsequent colonization of Daphnia by affecting ecological interactions between members of the microbiota. This resulted in differences in community assembly which, in turn, affected Daphnia growth. CONCLUSIONS: These results show that the composition of the pool of colonizing microbiota can be an important structuring factor of the microbiota assembly on Daphnia, affecting holobiont composition and host growth. These findings contribute to a better understanding of how the microbial environment can shape the holobiont composition and affect host-microbiota interactions. PMID- 29566773 TI - Psychotic-like experiences with cannabis use predict cannabis cessation and desire to quit: a cannabis discontinuation hypothesis. AB - BACKGROUND: Evidence suggests that cannabis-induced psychotic-like experiences may be a marker of psychosis proneness. The effect of such experiences on cannabis use has not systematically been examined. METHODS: We undertook a mixed methods online survey of 1231 cannabis users (including 926 continued users) using the Cannabis Experiences Questionnaire. We examined the effect of psychotic like and pleasurable experiences on cessation of cannabis and intention to quit. Socio-demographic variables, cannabis use parameters and substance misuse history were included as covariates. Free-text data explored subjective reasons for changes in use. RESULTS: Cessation of cannabis use was associated with greater psychotic-like experiences [p < 0.001, Exp(B) 1.262, 95% confidence interval (CI) 1.179-1.351], whilst continued cannabis users were more likely to report pleasurable experiences [p < 0.001, Exp(B) 0.717, 95% CI 0.662-0.776]. Intention to quit cannabis in continued users was associated with greater psychotic-like experiences [p < 0.003, Exp(B) 1.131, 95% CI 1.044-1.225], whilst intention to not quit was significantly associated with increased pleasurable experiences [p < 0.015, Exp(B) 0.892, 95% CI 0.814-0.978]. Whereas former users clearly ascribed cessation to negative experiences, continued users who expressed intention to quit less readily ascribed the intention to negative experiences. CONCLUSIONS: Elucidation of psychotic-like experiences may form the basis of a therapeutic intervention for those who wish to quit. Cessation in those with cannabis-induced psychotomimetic experiences may offset the risk for the development of a psychotic disorder, in this higher risk group. PMID- 29566772 TI - Platelet lysate as a novel serum-free media supplement for the culture of equine bone marrow-derived mesenchymal stem cells. AB - BACKGROUND: Mesenchymal stem cells (MSCs) produced for clinical purposes rely on culture media containing fetal bovine serum (FBS) which is xenogeneic and has the potential to significantly alter the MSC phenotype, rendering these cells immunogenic. As a result of bovine-derived exogenous proteins expressed on the cell surface, MSCs may be recognized by the host immune system as non-self and be rejected. Platelet lysate (PL) may obviate some of these concerns and shows promising results in human medicine as a possible alternative to FBS. Our goal was to evaluate the use of equine platelet lysate (ePL) pooled from donor horses in place of FBS to culture equine MSCs. We hypothesized that ePL, produced following apheresis, will function as the sole media supplement to accelerate the expansion of equine bone marrow-derived MSCs without altering their phenotype and their immunomodulatory capacity. METHODS: Platelet concentrate was obtained via plateletpheresis and ePL were produced via freeze-thaw and centrifugation cycles. Population doublings (PD) and doubling time (DT) of bone marrow-derived MSCs (n = 3) cultured with FBS or ePL media were calculated. Cell viability, immunophenotypic analysis, and trilineage differentiation capacity of MSCs were assessed accordingly. To assess the ability of MSCs to modulate inflammatory responses, E. coli lipopolysaccharide (LPS)-stimulated monocytes were cocultured with MSCs cultured in the two different media formulations, and cell culture supernatants were assayed for the production of tumor necrosis factor (TNF) alpha. RESULTS: Our results showed that MSCs cultured in ePL media exhibited similar proliferation rates (PD and DT) compared with those cultured in FBS at individual time points. MSCs cultured in ePL showed a statistically significant increased viability following a single washing step, expressed similar levels of MSC markers compared to FBS, and were able to differentiate towards the three lineages. Finally, MSCs cultured in ePL efficiently suppressed the release of TNF alpha when exposed to LPS-stimulated monocytes similar to those cultured in FBS. CONCLUSION: ePL has the potential to be used for the expansion of MSCs before clinical application, avoiding the concerns associated with the use of FBS.

AB - ABSTRACTCare aides working in nursing homes are often exposed to responsive behaviours in older adults living with Alzheimer's disease. As these behaviors may induce psychological distress, the current research aims to estimate the contribution of a set of variables on the psychological distress reported by care aides. Variables include perceived frequency of responsive behaviours, primary and secondary cognitive appraisal, and coping strategies. A total of ninety-two day care aides were recruited in nursing homes in the Quebec City area. Standard multiple regression was completed and findings show that frequency of responsive behaviours, primary appraisal of threat, secondary appraisal (feeling incapable of changing the situation) and seeking emotional support contribute to care aides' psychological distress. This study highlights the importance of responsive behaviours on the units and discusses the psychological mechanisms used by care aides. PMID- 29566775 TI - Food Crises and Food Safety Incidents in European Union, United States, and Maghreb Area: Current Risk Communication Strategies and New Approaches. AB - Globalization has created a dynamic market, which has dramatically intensified interchanges of goods and information as well as the flow of people among nations. This international phenomenon offers the consumer a choice between a wide variety of foods from diverse locations. However, there are challenges to improving food security and safety on a global scale; the major question is how food safety can be guaranteed while increasing the complexity of food supply chains. A food produced in a certain location usually contains ingredients, additives, and preservatives from different and distant origins. Although countries take several food control measures, their institutional and regulatory frameworks diverge widely, as do the definitions of food crisis, food incidents, and risk management approaches. The present review discusses some past food safety issues and lessons learned. Convergences and differences in the regulatory framework of food control agencies in different regions of the world are herein revealed. Emerging risks are also discussed, particularly the spread of antibiotic resistance in the food chain and the environment, as well as the rise of new antibiotic-resistant pathogenic strains with broader tolerance to environmental factors. PMID- 29566776 TI - Vitamin D Dietary Supplementation: Relationship with Chronic Heart Failure. AB - It is estimated that over 1 billion people worldwide have a deficiency of vitamin D, also known as hypovitaminosis D, which the World Health Organization has defined as a public health problem. Beyond its historical homeostasis regulatory function of calcium and phosphorus, in relation to the preservation of the skeletal system, several studies show today a close connection between hypovitaminosis D and the genesis of rheumatic, autoimmune, neoplastic, and cardiovascular diseases. With exclusive reference to cardiovascular aspects, multiple heart diseases such as hypertension, myocardial ischemia, and heart failures might have deficiency in vitamin D as an important causative factor. Because of the influence of concomitant pathologies caused by antibiotic resistant agents, the function of this vitamin should be critically evaluated. However, the role of vitamin D remains to be established; only a few studies have tested the effects of its supplementation in patients with chronic heart failure diseases, and reported results are unclear. It is important to implement studies in this field in order to assess the real benefits induced by vitamin D supplementation in cardiovascular patients and, in particular, in patients with heart failure. Should the research confirm actual clinical improvement after treatment with vitamin D, such a supplementation might represent a new low-cost therapeutic approach to improving quality of life.

AB - This paper uses the LC-quadrupole-time-of-flight MS technique to evaluate the behavioral characteristics of MS of 485 pesticides under different conditions and has developed an accurate mass database and spectra library. A high-throughput screening and confirmation method has been developed for the 485 pesticides in fruits and vegetables. Through the optimization of parameters such as accurate mass number, time of retention window, ionization forms, etc., the method has improved the accuracy of pesticide screening, thus avoiding the occurrence of false-positive and false-negative results. The method features a full scan of fragments, with 80% of pesticide qualitative points over 10, which helps increase pesticide qualitative accuracy. The abundant differences of fragment categories help realize the effective separation and qualitative identification of isomer pesticides. Four different fruits and vegetables-apples, grapes, celery, and tomatoes-were chosen to evaluate the efficiency of the method at three fortification levels of 5, 10, and 20 MUg/kg, and satisfactory results were obtained. With this method, a national survey of pesticide residues was conducted between 2012 and 2015 for 12 551 samples of 146 different fruits and vegetables collected from 638 sampling points in 284 counties across 31 provincial capitals/cities directly under the central government, which provided scientific data backup for ensuring pesticide residue safety of the fruits and vegetables consumed daily by the public. Meanwhile, the big data statistical analysis of the new technique also further proves it to be of high speed, high throughput, high accuracy, high reliability, and high informatization.

AB - This study was carried out with the aim of identifying and assessing methicillin resistant Staphylococcus aureus (MRSA) during lactic acid cheese storage. The study involved 30 assortments of lactic acid cheese and 21 cheeses with S. aureus TWP11616 (MRSA). Results showed low MRSA contamination levels in lactic acid cheese. The majority of cow and goat lactic acid cheese samples (more than 72%) were characterized by a low level of MRSA (<=10 CFU/g). With regard to cow and sheep lactic acid cheese, methicillin-resistant Staphylococcus spp. contamination levels of >=100 CFU/g were found in 88 and 100% of samples, respectively. The microbial dynamics of MRSA changes in lactic acid cheese suggest a significant reduction in contamination levels after 4 days of product storage, and this decrease is likely not dependent on the type of packaging method.

PMID- 29566781 TI - Mycobacterium tuberculosis, a cause of necrotising pneumonia in childhood: a case series. AB - SETTING: Tertiary care hospital, Western Cape, South Africa. DESIGN: Retrospective descriptive study of a case series of necrotising pneumonia (NP) in children associated with Mycobacterium tuberculosis presenting over a 4-year period in a country with high human immunodeficiency virus (HIV) and tuberculosis (TB) prevalence. OBJECTIVE: To describe the clinical and radiological features of, and treatment regimens and outcomes in, children with NP. RESULTS: Of 32 children (median age 16.5 months, interquartile range 10-33), 8 (25%) (median age 49 months) had NP associated with M. tuberculosis, 6 of whom were HIV-infected. Chest computed tomography (CT) was diagnostic in all cases: no radiological signs were suggestive of TB. There was no difference in the clinical picture, chest radiography or CT scan between M. tuberculosis-associated and bacterial NP. M. tuberculosis was cultured in 75% of cases; pleural fluid acid-fast bacilli was positive in an additional two cases. Surgery was required in 46% of the M. tuberculosis cases. At follow-up, 50% of these cases had complete radiological resolution similar to bacterial NP. CONCLUSION: This series highlights the fact that M. tuberculosis not only causes acute pneumonia in children, it also results in numerous complications. M. tuberculosis should be considered as a cause of NP in all children, especially HIV-infected children, living in high TB prevalence regions. PMID- 29566782 TI - Are LOD and LOQ Reliable Parameters for Sensitivity Evaluation of Spectroscopic Methods? AB - The limit of detection (LOD) and the limit of quantification (LOQ) are common parameters to assess the sensitivity of analytical methods. In this study, the LOD and LOQ of previously reported terbium sensitized analysis methods were calculated by different methods, and the results were compared with sensitivity parameters [lower limit of quantification (LLOQ)] of U.S. Food and Drug Administration guidelines. The details of the calibration curve and standard deviation of blank samples of three different terbium-sensitized luminescence methods for the quantification of mycophenolic acid, enrofloxacin, and silibinin were used for the calculation of LOD and LOQ. A comparison of LOD and LOQ values calculated by various methods and LLOQ shows a considerable difference. The significant difference of the calculated LOD and LOQ with various methods and LLOQ should be considered in the sensitivity evaluation of spectroscopic methods. PMID- 29566783 TI - Validation and Measurement Uncertainty Assessment of a Microbiological Method Using Generalized Pivotal Quantity Procedure and Monte-Carlo Simulation. AB - Recently, a novel and effective statistical tool called the uncertainty profile has been developed with the purpose of graphically assessing the validity and estimating the measurement uncertainty of analytical procedures. One way to construct the uncertainty profile is to compute the beta-content, gamma confidence tolerance interval. In this study, we propose a tolerance interval based on the combination of the generalized pivotal quantity procedure and Monte Carlo simulation. The uncertainty profile has been applied successfully in several fields. However, in order to further confirm its universality, this newer approach has been applied to assess the performance of an alternative procedure versus a reference procedure for counting of Escherichia coli bacteria in drinking water. Hence, the aims of this research were to expose how the uncertainty profile can be powerfully applied pursuant to ISO 16140 standards in the frame of interlaboratory study and how to easily make a decision concerning the validity of the procedure. The analysis of the results shows that after the introduction of a correction factor, the alternative procedure is deemed valid over the studied range because the uncertainty limits lie within the acceptability limits set at +/--0.3 log unit/100 ml for a beta = 66.7% and gamma = 90%. PMID- 29566784 TI - Antioxidant ?-cryptoxanthin enhances porcine oocyte maturation and subsequent embryo development in vitro. AB - Oxidative stress is partly responsible for the poor quality of IVM oocytes. The present study investigated the effects of the antioxidant beta-cryptoxanthin on the IVM of porcine oocytes and the in vitro development of the ensuing embryos. Oocytes were matured in IVM medium containing different concentrations of beta cryptoxanthin (0, 0.1, 1, 10 or 100MUM). Treatment with 1uM beta-cryptoxanthin (Group 1B) improved polar body extrusion and the expression of maturation-related genes in cumulus cells and oocytes compared with control. In addition, levels of reactive oxygen species decreased significantly in Group 1B, whereas there were significant increases in glutathione levels and expression of the antioxidant genes superoxide dismutase 1 and peroxiredoxin 5 in this group. After parthenogenetic activation, although the cleavage rate did not differ between the control and 1B groups, the blastocyst formation rate was higher in the latter. Moreover, the total number of cells per blastocyst and relative mRNA levels of pluripotency marker and antioxidant genes were significantly higher in the 1B compared with control group. These results demonstrate that beta-cryptoxanthin decreases oxidative stress in porcine oocytes and improves their quality and developmental potential. PMID- 29566786 TI - 30 Years and Counting. PMID- 29566785 TI - Temporally differential protein expression of glycolytic and glycogenic enzymes during in vitro preimplantation bovine embryo development. AB - Proteomic analyses are useful for understanding the metabolic pathways governing embryo development. This study investigated the presence of enzymes involved in glycolysis and glycogenesis in in vitro-produced bovine embryos at five developmental stages leading up to blastocyst formation. The enzymes examined were: (1) glycolytic: hexokinase-I (HK-I), phosphofructokinase-1 (PFK-1), pyruvate kinase mutase 1/2 (PKM-1/2), glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and (2) glycogenic: glycogen synthase kinase-3 isoforms alpha/ beta (GSK 3alpha/beta). Glucose transporter-1 (GLUT-1) was also analysed. The developmental stages examined were: (1) 2-4-cell, (2) 5-8-cell, (3) 16-cell, (4) morula and (5) expanded blastocyst. The enzymes HK-I, PFK-1, PKM-1/2, GAPDH and GLUT-1 were differentially expressed throughout all stages (P<0.05). GSK-3alpha and beta were also differentially expressed from the 2-4-cell to the expanded blastocyst stage (P<0.05) and GLUT-1 was identified throughout. The general trend was that the abundance of PFK1, GAPDH and PKM-1/2 decreased whereas HK-I, phospho-GSK3alpha (P GSK3alpha) and P-GSK3beta levels increased as the embryo advanced. In contrast, GLUT-1 expression peaked at the 16-cell stage. These data combined suggest that in vitro bovine embryo metabolism switches from being glycolytic-centric to glycogenic-centric around the 16-cell stage, the developmental window also characterised by embryonic genome activation.

PMID- 29566792 TI - An Integrative Framework for Sensory, Motor, and Cognitive Functions of the Posterior Parietal Cortex. AB - Throughout the history of modern neuroscience, the parietal cortex has been associated with a wide array of sensory, motor, and cognitive functions. The use of non-human primates as a model organism has been instrumental in our current understanding of how areas in the posterior parietal cortex (PPC) modulate our perception and influence our behavior. In this Perspective, we highlight a series of influential studies over the last five decades examining the role of the PPC in visual perception and motor planning. We also integrate long-standing views of PPC functions with more recent evidence to propose a more general model framework to explain integrative sensory, motor, and cognitive functions of the PPC.

PMID- 29566796 TI - Cerebral Embolic Risk During Transcatheter Mitral Valve Interventions: An Unaddressed and Unmet Clinical Need? AB - As new transcatheter mitral valve (MV) interventions continuously evolve, potential procedure-related adverse events demand careful investigation. The risk of cerebral embolic damage is ubiquitous in any left-sided structural heart intervention (and potentially linked to long-term neurocognitive sequelae); therefore, efforts to evaluate these aspects in the field of catheter-based MV procedures are justified. Given the peculiarities of MV anatomy, MV disease, and MV procedures, the lessons learned from other transcatheter heart interventions (i.e., transcatheter aortic valve replacement) cannot be directly translated to MV applications. Through a systematic assessment of available evidence, the authors present and discuss procedure- and patient-related factors potentially associated with cerebral embolic risk during catheter-based MV interventions. Given the paucity of available data in this field, future large, dedicated studies are needed to understand whether cerebral embolic injury represents a real clinical issue during MV procedures.

AB - We developed stable isotope labeling and mass spectrometry approaches to measure the kinetics of multiple isoforms and fragments of tau in the human central nervous system (CNS) and in human induced pluripotent stem cell (iPSC)-derived neurons. Newly synthesized tau is truncated and released from human neurons in 3 days. Although most tau proteins have similar turnover, 4R tau isoforms and phosphorylated forms of tau exhibit faster turnover rates, suggesting unique processing of these forms that may have independent biological activities. The half-life of tau in control human iPSC-derived neurons is 6.74 +/- 0.45 days and in human CNS is 23 +/- 6.4 days. In cognitively normal and Alzheimer's disease participants, the production rate of tau positively correlates with the amount of amyloid plaques, indicating a biological link between amyloid plaques and tau physiology.

AB - OBJECTIVES: The authors sought to study variation in the practice of balloon aortic (BAV) and pulmonary valvuloplasty (BPV). BACKGROUND: The IMPACT (IMProving Adult and Congenital Treatment) registry provides an opportunity to study practice variation in transcatheter interventions for congenital heart disease. METHODS: The authors studied BAV and BPV in the IMPACT registry from January 1, 2011, to September 30, 2015, using hierarchical multivariable models to measure hospital-level variation in: 1) the distribution of indications for intervention; and 2) in cases with "high resting gradient" as the indication, consistency with published guidelines. RESULTS: A total of 1,071 BAV cases at 60 hospitals and 2,207 BPV cases at 75 hospitals were included. The indication for BAV was high resting gradient in 82%, abnormal stress test or electrocardiogram (2%), left ventricular dysfunction (11%), and symptoms (5%). Indications for BPV were high resting gradient in 82%, right-left shunt (6%), right ventricular dysfunction (7%), and symptoms (5%). No association between hospital characteristics and distribution of indications was demonstrated. Among interventions performed for "high resting gradient," there was significant adjusted hospital-level variation in the rates of cases performed consistently with guidelines. For BAV, significant differences were seen across census regions, with hospitals in the East and South more likely to practice consistently than those in the Midwest and West (p = 0.005). For BPV, no association was found between hospital factors and rates of consistent practice, but there was significant interhospital variation (median rate ratio: 1.4; 95% confidence interval: 1.2 to 1.6; p < 0.001). CONCLUSIONS: There is measurable hospital-level variation in the practice of BAV and BPV. Further research is necessary to determine whether this affects outcomes or resource use.

AB - OBJECTIVES: The authors sought to assess the intermediate-term effects of percutaneous placed valves in the branch pulmonary artery (PA) position. BACKGROUND: Most patients with large right ventricular outflow tracts (RVOTs) are excluded from available percutaneous pulmonary valve options. In some of these patients, percutaneous branch PA valve implantation may be feasible. The longer term effects of valves in the branch PA position is unknown. METHODS: Retrospective data were collected on patients with significant pulmonary regurgitation who had a percutaneous branch PA valve attempted. RESULTS: Percutaneous branch PA valve implantation was attempted in 34 patients (18 bilateral and 16 unilateral). One-half of the patients were in New York Heart Association (NHYA) functional class III or IV pre-implantation. There were 2 failed attempts and 6 procedural complications. At follow-up, only 1 patient had more than mild valvar regurgitation. The right ventricular end-diastolic volume index decreased from 147 (range: 103 to 478) ml/m2 to 101 (range: 76 to 429) ml/m2, p < 0.01 (n = 16), and the right ventricular end-systolic volume index decreased from 88.5 (range: 41 to 387) ml/m2 to 55.5 (range: 40.2 to 347) ml/m2, p < 0.01 (n = 13). There were 5 late deaths. At a median follow-up of 2 years, all other patients were in NYHA functional class I or II. CONCLUSIONS: Percutaneous branch PA valve implantation results in a reduction in right ventricular volume with clinical benefit in the intermediate term. Until percutaneous valve technology for large RVOTs is refined and more widely available, branch PA valve implantation remains an option for select patients.

PMID- 29566801 TI - Transcatheter Pulmonary Valve Replacement With the Melody Valve in Small Diameter Expandable Right Ventricular Outflow Tract Conduits. AB - OBJECTIVES: This study sought to evaluate the safety, feasibility, and outcomes of transcatheter pulmonary valve replacement (TPVR) in conduits <=16 mm in diameter. BACKGROUND: The Melody valve (Medtronic, Minneapolis, Minnesota) is approved for the treatment of dysfunctional right ventricular outflow tract (RVOT) conduits >=16 mm in diameter at the time of implant. Limited data are available regarding the use of this device in smaller conduits. METHODS: The study retrospectively evaluated patients from 9 centers who underwent percutaneous TPVR into a conduit that was <=16 mm in diameter at the time of implant, and reported procedural characteristics and outcomes. RESULTS: A total of 140 patients were included and 117 patients (78%; median age and weight 11 years of age and 35 kg, respectively) underwent successful TPVR. The median original conduit diameter was 15 (range: 9 to 16) mm, and the median narrowest conduit diameter was 11 (range: 4 to 23) mm. Conduits were enlarged to a median diameter of 19 mm (29% larger than the implanted diameter), with no difference between conduits. There was significant hemodynamic improvement post-implant, with a residual peak RVOT pressure gradient of 7 mm Hg (p < 0.001) and no significant pulmonary regurgitation. During a median follow-up of 2.0 years, freedom from RVOT reintervention was 97% and 89% at 2 and 4 years, respectively, and there were no deaths and 5 cases of endocarditis (incidence rate 2.0% per patient-year). CONCLUSIONS: In this preliminary experience, TPVR with the Melody valve into expandable small diameter conduits was feasible and safe, with favorable early and long-term procedural and hemodynamic outcomes.

PMID- 29566803 TI - Conscious Sedation Versus General Anesthesia in Transcatheter Aortic Valve Replacement: The German Aortic Valve Registry. AB - OBJECTIVES: The aims of this study were to report on the use of local anesthesia or conscious sedation (LACS) and general anesthesia in transcatheter aortic valve replacement and to analyze the impact on outcome. BACKGROUND: Transcatheter aortic valve replacement can be performed in LACS or general anesthesia. Potential benefits of LACS, such as faster procedures and shorter hospital stays, need to be balanced with safety. METHODS: A total of 16,543 patients from the German Aortic Valve Registry from 2011 to 2014 were analyzed, and propensity matched analyses were performed to correct for potential selection bias. RESULTS: LACS was used in 49% of patients (8,121 of 16,543). In hospital, LACS was associated with lower rates of low-output syndrome, respiratory failure, delirium, cardiopulmonary resuscitation, and death. There was no difference in paravalvular leakage (II+) between LACS and general anesthesia in the entire population (5% vs. 4.8%; p = 0.76) or in the matched population (3.9% vs. 4.9%, p = 0.13). The risk for prolonged intensive care unit stay (>=3 days) was significantly reduced with LACS (odds ratio: 0.82; 95% confidence interval [CI]: 0.73 to 0.92; p = 0.001). Thirty-day mortality was lower with LACS in the entire population (3.5% vs. 4.9%; hazard ratio [HR]: 0.72; 95% CI: 0.60 to 0.86; p < 0.001) and in the matched population (2.8% vs. 4.6%; HR: 0.6; 95% CI: 0.45 to 0.8; p < 0.001). However, no differences in 1-year mortality between both groups in the entire population (16.5% vs. 16.9%; HR: 0.93; 95% CI: 0.85 to 1.02; p = 0.140) and in the propensity-matched population (14.1% vs. 15.5%; HR: 0.90; 95% CI: 0.78 to 1.03; p = 0.130) were observed. CONCLUSIONS: Use of LACS in transcatheter aortic valve replacement is safe, with fewer post-procedural complications and lower early mortality, suggesting its broad application.

PMID- 29566805 TI - Inclusion of Functional Status Measures in the Risk Adjustment of 30-Day Mortality After Transcatheter Aortic Valve Replacement: A Report From the Society of Thoracic Surgeons/American College of Cardiology TVT Registry. AB - OBJECTIVES: The aim of this study was to develop and validate a risk adjustment model for 30-day mortality after transcatheter aortic valve replacement (TAVR) that accounted for both standard clinical factors and pre-procedural health status and frailty. BACKGROUND: Assessment of risk for TAVR is important both for patient selection and provider comparisons. Prior efforts for risk adjustment have focused on in-hospital mortality, which is easily obtainable but can be biased because of early discharge of ill patients. METHODS: Using data from patients who underwent TAVR as part of the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry (June 2013 to May 2016), a hierarchical logistic regression model to estimate risk for 30-day mortality after TAVR based only on pre-procedural factors and access site was developed and internally validated. The model included factors from the original TVT Registry in-hospital mortality model but added the Kansas City Cardiomyopathy Questionnaire (health status) and gait speed (5-m walk test). RESULTS: Among 21,661 TAVR patients at 188 sites, 1,025 (4.7%) died within 30 days. Independent predictors of 30-day death included older age, low body weight, worse renal function, peripheral artery disease, home oxygen, prior myocardial infarction, left main coronary artery disease, tricuspid regurgitation, nonfemoral access, worse baseline health status, and inability to walk. The predicted 30-day mortality risk ranged from 1.1% (lowest decile of risk) to 13.8% (highest decile of risk). The model was able to stratify risk on the basis of patient factors with good discrimination (C = 0.71 [derivation], C = 0.70 [split-sample validation]) and excellent calibration, both overall and in key patient subgroups. CONCLUSIONS: A clinical risk model was developed for 30-day death after TAVR that included clinical data as well as health status and frailty. This model will facilitate tracking outcomes over time as TAVR expands to lower risk patients and to less experienced sites and will allow an objective comparison of short-term mortality rates across centers.

PMID- 29566812 TI - Transcatheter Aortic Valve Replacement in Patients With Low-Flow, Low-Gradient Aortic Stenosis: The TOPAS-TAVI Registry. AB - BACKGROUND: Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist on the usefulness of dobutamine stress echocardiography (DSE) before TAVR in these patients. OBJECTIVES: The authors sought to evaluate clinical outcomes and changes in left ventricular ejection fraction (LVEF) following TAVR in patients with classical LFLG-AS. METHODS: This multicenter registry included 287 patients with LFLG-AS undergoing TAVR. DSE was performed before TAVR in 234 patients and the presence of contractile reserve was defined as an increase of >=20% in stroke volume. Transthoracic echocardiography was repeated at hospital discharge and at 1-year follow-up. Clinical follow-up was obtained at 1 and 12 months, and yearly thereafter. RESULTS: The median Society of Thoracic Surgeons score of the study population was 7.7% (interquartile range 5.3% to 12.0%), and the mean LVEF and transvalvular gradient were 30.1 +/- 9.7% and 25.4 +/- 6.6 mm Hg, respectively. The presence of contractile reserve was observed in 45% of patients at DSE. Mortality rates were 3.8%, 20.1%, and 32.3% at 30 days, 1 year, and 2 years, respectively. On multivariable analysis, chronic obstructive pulmonary disease (p = 0.022) and lower hemoglobin values (p < 0.001) were associated with all-cause mortality. Lower hemoglobin values (p = 0.004) and moderate-to-severe aortic regurgitation post-TAVR (p = 0.018) were predictors of the composite of mortality and rehospitalization due to heart failure. LVEF increased by 8.3% (95% confidence interval: 6% to 11%) at 1-year follow-up, and the lack of prior coronary artery bypass graft (p = 0.004), a lower LVEF at baseline (p < 0.001), and a lower stroke volume index at baseline (p = 0.019) were associated with greater increase in LVEF. The absence of contractile reserve at baseline DSE was not associated with any negative effect on clinical outcomes or LVEF changes at follow-up. CONCLUSIONS: TAVR was associated with good periprocedural outcomes in patients with LFLG-AS. However, approximately one-third of LFLG-AS TAVR recipients died at 2-year follow-up, with pulmonary disease, anemia, and residual paravalvular leaks associated with poorer outcomes. LVEF improved following TAVR, but DSE failed to predict clinical outcomes or LVEF changes over time.

AB - BACKGROUND: Left ventricular ejection fraction (LVEF) is reduced in a subset of patients with severe aortic stenosis (AS). OBJECTIVES: The authors sought to determine the temporal course of reduced LVEF, its predictors, and its impact on prognosis in severe AS. METHODS: Serial echocardiograms of 928 consecutive patients with first-time diagnosis of severe AS (aortic valve area [AVA] <=1 cm2) who had at least 1 echocardiogram before the diagnosis were evaluated. A total of 3,684 echocardiograms (median 3 studies per patient) within the preceding 10 years were analyzed. RESULTS: At the initial diagnosis, 196 (21%) patients had an LVEF <50% (35.1 +/- 9.7%) and 732 (79%) had an LVEF >=50% (64.2 +/- 6.1%). LVEF deterioration had begun before AS became severe for those with an LVEF <50% and accelerated after AVA reached 1.2 cm2, whereas mean LVEF remained >60% in patients with LVEF >=50% at initial diagnosis. The strongest predictor for LVEF deterioration was LVEF <60% at 3 years before AS became severe (odds ratio: 0.86; 95% confidence interval: 0.83 to 0.89; p < 0.001). During the median follow-up of 3.3 years, mortality was significantly worse, not only for patients with an LVEF <50%, but for patients with an LVEF of 50% <= LVEF <60% compared with patients with an LVEF >=60% even after aortic valve replacement (p < 0.001). CONCLUSIONS: In patients with severe AS and reduced LVEF, a decline in LVEF began before AS became severe and accelerated after AVA reached 1.2 cm2. LVEF <60% in the presence of moderate AS predicts further deterioration of LVEF and appears to represent abnormal LVEF in AS.

AB - To identify novel genes associated with ALS, we undertook two lines of investigation. We carried out a genome-wide association study comparing 20,806 ALS cases and 59,804 controls. Independently, we performed a rare variant burden analysis comparing 1,138 index familial ALS cases and 19,494 controls. Through both approaches, we identified kinesin family member 5A (KIF5A) as a novel gene associated with ALS. Interestingly, mutations predominantly in the N-terminal motor domain of KIF5A are causative for two neurodegenerative diseases: hereditary spastic paraplegia (SPG10) and Charcot-Marie-Tooth type 2 (CMT2). In contrast, ALS-associated mutations are primarily located at the C-terminal cargo binding tail domain and patients harboring loss-of-function mutations displayed an extended survival relative to typical ALS cases. Taken together, these results broaden the phenotype spectrum resulting from mutations in KIF5A and strengthen the role of cytoskeletal defects in the pathogenesis of ALS.

PMID- 29566816 TI - Cardiac Resynchronization Therapy in Patients With Heart Failure and Narrow QRS Complexes. AB - BACKGROUND: Cross correlation analysis (CCA) using tissue Doppler imaging has been shown to be associated with outcome after cardiac resynchronization therapy (CRT) in patients with heart failure (HF) with wide QRS. However, its significance in patients with narrow QRS treated with CRT is unknown. OBJECTIVES: The aim of the current study was to investigate the association of mechanical activation delay by CCA with study outcome in patients with HF enrolled in the EchoCRT trial. METHODS: Baseline CCA could be performed from tissue Doppler imaging in the apical views in 807 of 809 (99.7%) enrolled patients, and 6-month follow-up could be performed in 610 of 635 (96%) patients with available echocardiograms. Patients with a pre-specified maximal activation delay >=35 ms were considered to have significant delay. The study outcome was HF hospitalization or death. RESULTS: Of 807 patients, 375 (46%) did not have delayed mechanical activation at baseline by CCA. Patients without delayed mechanical activation who were randomized to CRT-On compared with CRT-Off had an increased risk of poor outcome (hazard ratio: 1.70; 95% confidence interval: 1.13 to 2.55; p = 0.01) with a significant interaction term (p = 0.04) between delayed mechanical activation and device randomization for the endpoint. Among patients with paired baseline and follow-up data with no events before 6-month follow-up (n = 541), new-onset delayed mechanical activation in the CRT-On group showed a significant increase in unfavorable events (hazard ratio: 3.73; 95% confidence interval: 1.15 to 12.14; p = 0.03). CONCLUSIONS: In the EchoCRT population, absence of delayed mechanical activation by CCA was significantly associated with poor outcomes, possibly due to the onset of new delayed mechanical activation with CRT pacing.

PMID- 29566818 TI - Improved Survival After the Ross Procedure Compared With Mechanical Aortic Valve Replacement. AB - BACKGROUND: It is unclear whether the Ross procedure offers superior survival compared with mechanical aortic valve replacement (AVR). OBJECTIVES: This study evaluated experience and compared long-term survival between the Ross procedure and mechanical AVR. METHODS: Between 1992 and 2016, a total of 392 Ross procedures were performed. These were compared with 1,928 isolated mechanical AVRs performed during the same time period as identified using the University of Melbourne and Australia and New Zealand Society of Cardiac and Thoracic Surgeons' Cardiac Surgery Databases. Only patients between 18 and 65 years of age were included. Propensity-score matching was performed for risk adjustment. RESULTS: Ross procedure patients were younger, and had fewer cardiovascular risk factors. The Ross procedure was associated with longer cardiopulmonary bypass and aortic cross-clamp times. Thirty-day mortality was similar (Ross, 0.3%; mechanical, 0.8%; p = 0.5). Ross procedure patients experienced superior unadjusted long-term survival at 20 years (Ross, 95%; mechanical, 68%; p < 0.001). Multivariable analysis showed the Ross procedure to be associated with a reduced risk of late mortality (hazard ratio: 0.34; 95% confidence internal: 0.17 to 0.67; p < 0.001). Among 275 propensity-score matched pairs, Ross procedure patients had superior survival at 20 years (Ross, 94%; mechanical, 84%; p = 0.018). CONCLUSIONS: In this Australian, propensity-score matched study, the Ross procedure was associated with better long-term survival compared with mechanical AVR. In younger patients, with a long life expectancy, the Ross procedure should be considered in centers with sufficient expertise.

AB - BACKGROUND: Experimental and clinical studies show that prematurity leads to altered left ventricular (LV) structure and function with preserved resting LV ejection fraction (EF). Large-scale epidemiological data now links prematurity to increased early heart failure risk. OBJECTIVES: The authors performed echocardiographic imaging at prescribed exercise intensities to determine whether preterm-born adults have impaired LV functional response to physical exercise. METHODS: We recruited 101 normotensive young adults born preterm (n = 47; mean gestational age 32.8 +/- 3.2 weeks) and term (n = 54) for detailed cardiovascular phenotyping. Full clinical resting and exercise stress echocardiograms were performed, with apical 4-chamber views collected while exercising at 40%, 60%, and 80% of peak exercise capacity, determined by maximal cardiopulmonary exercise testing. RESULTS: Preterm-born individuals had greater LV mass (p = 0.015) with lower peak systolic longitudinal strain (p = 0.038) and similar EF to term-born control subjects at rest (p = 0.62). However, by 60% exercise intensity, EF was 6.7% lower in preterm subjects (71.9 +/- 8.7% vs 78.6 +/- 5.4%; p = 0.004) and further declined to 7.3% below the term-born group at 80% exercise intensity (69.8 +/- 6.4% vs 77.1 +/- 6.3%; p = 0.004). Submaximal cardiac output reserve was 56% lower in preterm-born subjects versus term-born control subjects at 40% of peak exercise capacity (729 +/- 1,162 ml/min/m2 vs. 1,669 +/- 937 ml/min/m2; p = 0.021). LV length and resting peak systolic longitudinal strain predicted EF increase from rest to 60% exercise intensity in the preterm group (r = 0.68, p = 0.009 and r = 0.56, p = 0.031, respectively). CONCLUSIONS: Preterm-born young adults had impaired LV response to physiological stress when subjected to physical exercise, which suggested a reduced myocardial functional reserve that might help explain their increased risk of early heart failure.

PMID- 29566822 TI - Coronary Angiography and Percutaneous Coronary Intervention After Transcatheter Aortic Valve Replacement. AB - Transcatheter aortic valve replacement (TAVR) has revolutionized the management of patients with symptomatic severe aortic stenosis, and indications are expanding towards treating younger patients with lower-risk profiles. Given the progressive nature of coronary artery disease and its high prevalence in those with severe aortic stenosis, coronary angiography and percutaneous coronary intervention will become increasingly necessary in patients after TAVR. There are some data suggesting that there are technical difficulties with coronary re engagement, particularly in patients with self-expanding valves that, by design, extend above the coronary ostia. The authors review the challenges of coronary angiography and percutaneous coronary intervention post-TAVR and examine the geometric interactions between currently approved transcatheter aortic valves and coronary ostia, while providing a practical guide on how to manage these potentially complex situations.

PMID- 29566830 TI - Affordability Challenges to Value-Based Pricing: Mass Diseases, Orphan Diseases, and Cures. AB - OBJECTIVES: To analyze how value-based pricing (VBP), which grounds the price paid for pharmaceuticals in their value, can manage "affordability" challenges, defined as drugs that meet cost-effectiveness thresholds but are "unaffordable" within the short-run budget. METHODS: Three specific contexts are examined, drawing on recent experience. First, an effective new treatment for a chronic, progressive disease, such as hepatitis C, creates a budget spike that is transitory because initial prevalence is high, relative to current incidence. Second, "cures" that potentially provide lifetime benefits may claim abnormally high VBP prices, with high immediate budget impact potentially/partially offset by deferred cost savings. Third, although orphan drugs in principle target rare diseases, in aggregate they pose affordability concerns because of the growing number of orphan indications and increasingly high prices. RESULTS: For mass diseases, the transitory budget impact of treating the accumulated patient stock can be managed by stratified rollout that delays treatment of stable patients and prioritizes patients at high risk of deterioration. Delay spreads the budget impact and permits potential savings from launch of competing treatments. For cures, installment payments contingent on outcomes could align payment flows and appropriately shift risk to producers. This approach, however, entails high administrative and incentive costs, especially if applied across multiple payers in the United States. For orphan drugs, the available evidence on research and development trends and returns argues against the need for a higher VBP threshold to incentivize research and development in orphan drugs, given existing statutory benefits under orphan drug legislation. PMID- 29566831 TI - The ICER Value Framework: Integrating Cost Effectiveness and Affordability in the Assessment of Health Care Value. AB - What should be the relationship between the concepts of cost effectiveness and affordability in value assessments for health care interventions? This question has received greater attention in recent years given increasing financial pressures on health systems, leading to different views on how assessment reports and decision-making processes can provide the best structure for considering both elements. In the United States, the advent of explicit value frameworks to guide drug assessments has also focused attention on this issue, driven in part by the prominent inclusion of affordability within the value framework used to guide reports from the Institute for Clinical and Economic Review. After providing a formal definition of affordability for health care systems, this article argues that, even after using empirical estimates of true health system opportunity cost, cost-effectiveness thresholds cannot by themselves be set in a way that subsumes questions about short-term affordability. The article then presents an analysis of different approaches to integrating cost effectiveness and budget impact assessments within information to guide decision making. The evolution and experience with the Institute for Clinical and Economic Review value framework are highlighted, providing lessons learned and guiding principles for future efforts to bring measures of affordability within the scope of value assessment. PMID- 29566832 TI - Resolving the "Cost-Effective but Unaffordable" Paradox: Estimating the Health Opportunity Costs of Nonmarginal Budget Impacts. AB - Considering whether or not a proposed investment (an intervention, technology, or program of care) is affordable is really asking whether the benefits it offers are greater than its opportunity cost. To say that an investment is cost effective but not affordable must mean that the (implicit or explicit) "threshold" used to judge cost-effectiveness does not reflect the scale and value of the opportunity costs. Existing empirical estimates of health opportunity costs are based on cross-sectional variation in expenditure and mortality outcomes by program budget categories (PBCs) and do not reflect the likely effect of nonmarginal budget impacts on health opportunity costs. The UK Department of Health regularly updates the needs-based target allocation of resources to local areas of the National Health Service (NHS), creating two subgroups of local areas (those under target allocation and those over). These data provide the opportunity to explore how the effects of changes in health care expenditure differ with available resources. We use 2008-2009 data to evaluate two econometric approaches to estimation and explore a range of criteria for accepting subgroup specific effects for differences in expenditure and outcome elasticities across the 23 PBCs. Our results indicate that health opportunity costs arising from an investment imposing net increases in expenditure are underestimated unless account is taken of likely nonmarginal effects. They also indicate the benefits (reduced health opportunity costs or increased value-based price of a technology) of being able to "smooth" these nonmarginal budget impacts by health care systems borrowing against future budgets or from manufacturers offering "mortgage" type arrangements. PMID- 29566833 TI - Paying for Cures: Perspectives on Solutions to the "Affordability Issue". AB - Curative therapies and other medicines considered "game-changing" in terms of health gain can be accompanied by high demand and high list prices that pose budget challenges to public and private payers and health systems-the so-called affordability issue. These challenges are exacerbated when longer term effectiveness, and thus value for money, is uncertain, but they can arise even when treatments are proven to be highly cost-effective at the time of launch. This commentary reviews innovative payment solutions proposed in the literature to address the affordability issue, including the use of credit markets and of staged payments linked to patient outcomes, and draws on discussions with payers in the United States and Europe on the feasibility or desirability of operationalizing any of the alternative financing and payment strategies that appear in the literature. This included a small number of semistructured interviews. We conclude that there is a mismatch between the enthusiasm in the academic literature for developing new approaches and the scepticism of payers that they can work or are necessary. For the foreseeable future, affordability pressures will continue to be handled by aggressive price bargaining, high co pays (in systems in which this is possible), and restricting access to subgroups of patients. Of the mechanisms we explored, outcomes-based payments were of most interest to payers, but the costs associated with operating such schemes, together with implementation challenges, did not make them an attractive option for managing affordability.

AB - BACKGROUND: The use of cost-effectiveness analysis for medical devices has proven to be challenging because of the existence of the learning effects in the device operator interactions. The need for the relevant analytical framework for assessing the economic value of such technologies has been recognized. OBJECTIVES: To present a modified difference-in-differences (DID) cost effectiveness methodology that facilitates visualization of a new health technology's learning curve. METHODS: Using the Premier Perspective database (Premier Inc., Charlotte, NC), we examined the impact of physicians adopting a bipolar sealer (BPS) to control blood loss in primary unilateral total knee arthroplasties on hospital lengths of stay and total hospitalization costs when compared with two control groups. In our DID approach, we substituted month-from adoption for the calendar-month-of-adoption in both graphical representations and ordinary least-squares regression results to estimate the effect of the BPS. RESULTS: The results clearly demonstrated a learning curve associated with the adoption of the BPS technology. Although the reductions in length of stay were immediate, the first postadoption year costs increased by $1335 (extrahospital controls) to $1565 (within-hospital controls). Importantly, and also consistent with a learning curve hypothesis, these initial higher costs were offset by subsequent cost savings in the second and third years postadoption. CONCLUSIONS: The presented modified DID approach is a suitable and versatile analytical tool for economic evaluation of a slowly diffusing medical device or health technology. It provides a better understanding of the potential learning effects associated with relevant interventions. PMID- 29566836 TI - Resource Use and Cost of Alzheimer's Disease in France: 18-Month Results from the GERAS Observational Study. AB - BACKGROUND: There is little longitudinal data on resource use and costs associated with Alzheimer's disease (AD) in France. OBJECTIVES: To evaluate resource use and societal costs associated with AD in a French cohort of patients and their caregivers and the effect of patient cognitive decline on costs over an 18-month period. METHODS: Community-dwelling patients with mild, moderate, or moderately severe/severe AD dementia (n = 419) were followed-up for 18 months. Total societal costs were estimated by applying 2010 unit costs to resource use, including outpatient visits, hospital days, institutionalization, and caregiver hours. Cognitive function was assessed by Mini-Mental State Examination scores. RESULTS: Mean cumulative total costs over the 18-month period were ?24,140 for patients with mild AD dementia, ?34,287 for those with moderate AD dementia, and ?44,171 for those with moderately severe/severe AD dementia (P < 0.001; ANOVA comparison between severity groups). The biggest contributor to total societal costs was caregiver informal care (>50% of total costs at all stages of AD dementia). Cognitive decline (>=3-point decrease in Mini-Mental State Examination score or institutionalization) was associated with a 12.5% increase in total costs (P = 0.02). Significant differences were observed across severity groups for caregiver time (P < 0.001); mean monthly caregiver time increased at each time point over the 18 months in each severity group. CONCLUSIONS: Increasing severity of AD dementia in France is associated with increased use of resources as well as increased total societal and patient costs; informal care was the greatest cost contributor. Clinically meaningful cognitive decline is associated with significantly increased costs. PMID- 29566837 TI - Economic Evaluation of Treating Skeletal-Related Events among Prostate Cancer Patients. AB - OBJECTIVES: To evaluate the economic burden of treating skeletal-related events (SREs) in prostate cancer (PC) patients with bone metastasis from an insurer perspective. METHODS: We conducted a retrospective cohort analysis using claims data. PC patients with bone metastasis were identified in the MarketScan Databases between January 1, 2004, and March 1, 2014. The propensity score matching approach was used to match patients with SREs to those without SREs. A pseudo-SRE date was assigned to the control group. We compared 6-month and 12 month total costs of patients between two groups after the SRE or pseudo-SRE date. All costs were adjusted to 2014 US$. RESULTS: We identified 4083 PC men with bone metastasis, from which 787 patients with SREs were matched (1:1) to those without SREs. On average, the total 6-month cost of treating patients with SREs was $43,746 compared with $25,956 in the matched control cohort (P < 0.05). The largest proportion of differences in costs between the two groups was incurred in the first month after the SRE index date or the pseudo-SRE date ($14,979 vs. $4,849; P < 0.05) and was mostly attributable to outpatient visits (43.4%; P < 0.05) and inpatient hospitalization (33.1%; P < 0.05). The total cost per patient over the 12-month period was $22,171 higher among patients with SREs than among patients without SREs (P < 0.05). CONCLUSIONS: Our findings suggest that SREs impose considerable burden on health resource utilization for payers. Costs attributable to SREs were substantial. Most costs were incurred in the first month after the occurrence of SREs. Although costs decreased thereafter, they remained significantly higher for patients with SREs in subsequent months compared with patients without SREs. PMID- 29566838 TI - Cost-Effectiveness of Antibiotic Prophylaxis Strategies for Transrectal Prostate Biopsy in an Era of Increasing Antimicrobial Resistance. AB - OBJECTIVES: To determine the optimal antibiotic prophylaxis strategy for transrectal prostate biopsy (TRPB) as a function of the local antibiotic resistance profile. METHODS: We developed a decision-analytic model to assess the cost-effectiveness of four antibiotic prophylaxis strategies: ciprofloxacin alone, ceftriaxone alone, ciprofloxacin and ceftriaxone in combination, and directed prophylaxis selection based on susceptibility testing. We used a payer's perspective and estimated the health care costs and quality-adjusted life-years (QALYs) associated with each strategy for a cohort of 66-year-old men undergoing TRPB. Costs and benefits were discounted at 3% annually. Base-case resistance prevalence was 29% to ciprofloxacin and 7% to ceftriaxone, reflecting susceptibility patterns observed at the Minneapolis Veterans Affairs Health Care System. Resistance levels were varied in sensitivity analysis. RESULTS: In the base case, single-agent prophylaxis strategies were dominated. Directed prophylaxis strategy was the optimal strategy at a willingness-to-pay threshold of $50,000/QALY gained. Relative to the directed prophylaxis strategy, the incremental cost-effectiveness ratio of the combination strategy was $123,333/QALY gained over the lifetime time horizon. In sensitivity analysis, single-agent prophylaxis strategies were preferred only at extreme levels of resistance. CONCLUSIONS: Directed or combination prophylaxis strategies were optimal for a wide range of resistance levels. Facilities using single-agent antibiotic prophylaxis strategies before TRPB should re-evaluate their strategies unless extremely low levels of antimicrobial resistance are documented. PMID- 29566839 TI - Cost-Effectiveness of First-Line Sevelamer and Lanthanum versus Calcium-Based Binders for Hyperphosphatemia of Chronic Kidney Disease. AB - BACKGROUND: Phosphate binders are used to treat hyperphosphatemia among patients with chronic kidney disease (CKD). OBJECTIVES: To conduct an economic evaluation comparing calcium-free binders sevelamer and lanthanum with calcium-based binders for patients with CKD. METHODS: Effectiveness data were obtained from a recent meta-analysis of randomized trials. Effectiveness was measured as life-years gained and translated to quality-adjusted life-years (QALYs) using utility weights from the literature. A Markov model consisting of non-dialysis-dependent (NDD)-CKD, dialysis-dependent (DD)-CKD, and death was developed to estimate the incremental costs and effects of sevelamer and lanthanum versus those of calcium based binders. A lifetime horizon was used and both costs and effects were discounted at 1.5%. All costs are presented in 2015 Canadian dollars from the Canadian public payer perspective. Results of probabilistic sensitivity analysis were presented using cost-effectiveness acceptability curves. Sensitivity analyses were conducted for risk pooling methods, omission of dialysis costs, and persistence of drug effects on mortality. RESULTS: Sevelamer resulted in an incremental cost-effectiveness ratio of $106,522/QALY for NDD-CKD and $133,847/QALY for DD-CKD cohorts. Excluding dialysis costs, sevelamer was cost effective in the NDD-CKD cohort ($5,847/QALY) and the DD-CKD cohort ($11,178/QALY). Lanthanum was dominated regardless of whether dialysis costs were included. CONCLUSIONS: Existing evidence does not clearly support the cost effectiveness of non-calcium-containing phosphate binders (sevelamer and lanthanum) relative to calcium-containing phosphate binders in DD-CKD patients. Our study suggests that sevelamer may be cost-effective before dialysis onset. Because of the remaining uncertainty in several clinically relevant outcomes over time in DD-CKD and NDD-CKD patients, further research is encouraged. PMID- 29566840 TI - Real-World Evidence: Useful in the Real World of US Payer Decision Making? How? When? And What Studies? AB - OBJECTIVES: To examine how real-world evidence (RWE) is currently perceived and used in managed care environments, especially to inform pharmacy and therapeutic (P&T) committee decisions, to assess which study factors (e.g., data, design, and funding source) contribute to RWE utility in decisions, and to identify barriers to consideration of RWE studies in P&T decision making. METHODS: We conducted focus groups/telephone-based interviews and surveys to understand perceptions of RWE and assess awareness, quality, and relevance of two high-profile examples of published RWE studies. A purposive sample comprised 4 physicians, 15 pharmacists, and 1 researcher representing 18 US health plans and health system organizations. RESULTS: Participants reported that RWE was generally used, or useful, to inform safety monitoring, utilization management, and cost analysis, but less so to guide P&T decisions. Participants were not aware of the two sample RWE studies but considered both studies to be valuable. Relevant research questions and outcomes, transparent methods, study quality, and timely results contribute to the utility of published RWE. Perceived organizational barriers to the use of published RWE included lack of skill, training, and timely study results. CONCLUSIONS: Payers recognize the value of RWE, but use of such studies to inform P&T decisions varies from organization to organization and is limited. Relevance to payers, timeliness, and transparent methods were key concerns with RWE. Participants recognized the need for continuing education on evaluating and using RWE to better understand the study methods, findings, and applicability to their organizations. PMID- 29566841 TI - Sensitivity of Claims-Based Algorithms to Ascertain Smoking Status More Than Doubled with Meaningful Use. AB - BACKGROUND: The "meaningful use of certified electronic health record" policy requires eligible professionals to record smoking status for more than 50% of all individuals aged 13 years or older in 2011 to 2012. OBJECTIVES: To explore whether the coding to document smoking behavior has increased over time and to assess the accuracy of smoking-related diagnosis and procedure codes in identifying previous and current smokers. METHODS: We conducted an observational study with 5,423,880 enrollees from the year 2009 to 2014 in the Truven Health Analytics database. Temporal trends of smoking coding, sensitivity, specificity, positive predictive value, and negative predictive value were measured. RESULTS: The rate of coding of smoking behavior improved significantly by the end of the study period. The proportion of patients in the claims data recorded as current smokers increased 2.3-fold and the proportion of patients recorded as previous smokers increased 4-fold during the 6-year period. The sensitivity of each International Classification of Diseases, Ninth Revision, Clinical Modification code was generally less than 10%. The diagnosis code of tobacco use disorder (305.1X) was the most sensitive code (9.3%) for identifying smokers. The specificities of these codes and the Current Procedural Terminology codes were all more than 98%. CONCLUSIONS: A large improvement in the coding of current and previous smoking behavior has occurred since the inception of the meaningful use policy. Nevertheless, the use of diagnosis and procedure codes to identify smoking behavior in administrative data is still unreliable. This suggests that quality improvements toward medical coding on smoking behavior are needed to enhance the capability of claims data for smoking-related outcomes research. PMID- 29566842 TI - What Is the Evidence from Past National Institute of Health and Care Excellence Single-Technology Appraisals Regarding Company Submissions with Base-Case Incremental Cost-Effectiveness Ratios of Less Than L10,000/QALY? AB - BACKGROUND: The National Institute for Health and Care Excellence has recently proposed that company submissions with a base-case incremental cost-effectiveness ratio (ICER) of less than L10,000/quality-adjusted life-year (QALY) might be eligible for a "fast-track" appraisal. OBJECTIVES: To explore outcomes relating to previously conducted single-technology appraisals (STAs) with base-case ICERs of less than L10,000/QALY. METHODS: All STAs with published guidance from 2009 to 2016 were included; those with company base-case ICERs of less than L10,000/QALY were identified and analyzed. A secondary analysis was also conducted for those with a company base-case ICER of L10,000 to L15,000/QALY. Relevant data were extracted and presented in a narrative and in tables. RESULTS: In total, 15% (26 of 171) of STAs included a company submission with a base-case ICER of less than L10,000/QALY. Of these, 73% (19 of 26) were given positive recommendations after the first Appraisal Committee (AC) meeting, whereas 27% (7 of 26) were initially given a Minded No before receiving a positive recommendation in the final appraisal determination, albeit with restricted recommendations for three technologies. Five STAs had company base-case ICERs of L10,000 to L15,000/QALY and all received a positive recommendation after the first AC meeting. CONCLUSIONS: Most previous STAs with a company base-case ICER of L10,000 or even L15,000/QALY received a positive recommendation after the first AC meeting, but a number of them proved more complicated and required detailed appraisal, which influenced the final recommendation. This finding might have implications for the proposed fast-track process of the National Institute for Health and Care Excellence. PMID- 29566843 TI - The Importance of Model Structure in the Cost-Effectiveness Analysis of Primary Care Interventions for the Management of Hypertension. AB - BACKGROUND: Management of hypertension can lead to significant reductions in blood pressure, thereby reducing the risk of cardiovascular disease. Modeling the course of cardiovascular disease is not without complications, and uncertainty surrounding the structure of a model will almost always arise once a choice of a model structure is defined. OBJECTIVES: To provide a practical illustration of the impact on the results of cost-effectiveness of changing or adapting model structures in a previously published cost-utility analysis of a primary care intervention for the management of hypertension Targets and Self-Management for the Control of Blood Pressure in Stroke and at Risk Groups (TASMIN-SR). METHODS: The case study assessed the structural uncertainty arising from model structure and from the exclusion of secondary events. Four alternative model structures were implemented. Long-term cost-effectiveness was estimated and the results compared with those from the TASMIN-SR model. RESULTS: The main cost effectiveness results obtained in the TASMIN-SR study did not change with the implementation of alternative model structures. Choice of model type was limited to a cohort Markov model, and because of the lack of epidemiological data, only model 4 captured structural uncertainty arising from the exclusion of secondary events in the case study model. CONCLUSIONS: The results of this study indicate that the main conclusions drawn from the TASMIN-SR model of cost-effectiveness were robust to changes in model structure and the inclusion of secondary events. Even though one of the models produced results that were different to those of TASMIN-SR, the fact that the main conclusions were identical suggests that a more parsimonious model may have sufficed. PMID- 29566844 TI - Associations of Smoking, Physical Inactivity, Heavy Drinking, and Obesity with Quality-Adjusted Life Expectancy among US Adults with Depression. AB - OBJECTIVES: To examine associations between four health behaviors (smoking, physical inactivity, heavy alcohol drinking, and obesity) and three health indices (health-related quality of life, life expectancy, and quality-adjusted life expectancy (QALE)) among US adults with depression. METHODS: Data were obtained from the 2006, 2008, and 2010 Behavioral Risk Factor Surveillance System data. The EuroQol five-dimensional questionnaire (EQ-5D) health preference scores were estimated on the basis of extrapolations from the Centers for Disease Control and Prevention's healthy days measures. Depression scores were estimated using the eight-item Patient Health Questionnaire. Life expectancy estimates were obtained from US life tables, and QALE was estimated from a weighted combination of the EQ-5D scores and the life expectancy estimates. Outcomes were summarized by depression status for the four health behaviors (smoking, physical inactivity, heavy alcohol drinking, and obesity). RESULTS: For depressed adults, current smokers and the physically inactive had significantly lower EQ-5D scores (0.040 and 0.171, respectively), shorter life expectancy (12.9 and 10.8 years, respectively), and substantially less QALE (8.6 and 10.9 years, respectively). For nondepressed adults, estimated effects were similar but smaller. Heavy alcohol drinking among depressed adults, paradoxically, was associated with higher EQ-5D scores but shorter life expectancy. Obesity was strongly associated with lower EQ-5D scores but only weakly associated with shorter life expectancy. CONCLUSIONS: Among depressed adults, physical inactivity and smoking were strongly associated with lower EQ-5D scores, life expectancy, and QALE, whereas obesity and heavy drinking were only weakly associated with these indices. These results suggest that reducing physical inactivity and smoking would improve health more among depressed adults.

PMID- 29566846 TI - Resident Education Curriculum in Pediatric and Adolescent Gynecology: The Short Curriculum 2.0. AB - The degree of exposure to pediatric and adolescent gynecology (PAG) varies across residency programs in obstetrics and gynecology and pediatrics. Nevertheless, these programs are responsible for training residents and providing opportunities within their programs to fulfill PAG learning objectives. To that end, the North American Society for Pediatric and Adolescent Gynecology has taken a leadership role in PAG resident education by creating and systematically updating the Short Curriculum. This curriculum outlines specific learning objectives that are central to PAG education and lists essential resources for learners' reference. This updated curriculum replaces the previous 2014 publication with added content, resources, and updated references. Additionally, attention to the needs of learners in pediatrics and adolescent medicine is given greater emphasis in this revised North American Society for Pediatric and Adolescent Gynecology Short Curriculum 2.0.

PMID- 29566849 TI - Pathogenesis of uterine adenomyosis: invagination or metaplasia? AB - Adenomyosis is a commonly diagnosed estrogen-dependent gynecological disorder that causes pelvic pain, abnormal uterine bleeding, and infertility. Despite its prevalence and severity of symptoms, its pathogenesis and etiology have not yet been elucidated. The aim of this manuscript is to review the different hypotheses on the origin of adenomyotic lesions and the mechanisms involved in the evolution and progression of the disease. Two main theories have been proposed to explain the origin of adenomyosis. The most common suggests involvement of tissue injury and the repair mechanism and claims that adenomyosis results from invagination of the endometrial basalis into the myometrium. An alternative theory maintains that adenomyotic lesions result from metaplasia of displaced embryonic pluripotent Mullerian remnants or differentiation of adult stem cells. Previous investigations performed in human adenomyotic lesions and corroborated by studies in mice supported the involvement of the epithelial-mesenchymal transition process in the early stages of progression and spread of adenomyosis. However, studies conducted in a recently developed baboon model indicate that collective cell migration may be implicated in the later events of invasion. This suggests that the invasiveness of this complex uterine disorder is not driven by a single mechanism of migration but by a time-dependent combination of two processes. PMID- 29566850 TI - Symptoms and classification of uterine adenomyosis, including the place of hysteroscopy in diagnosis. AB - Where histology used the presence of glands and/or stroma in the myometrium as pathognomonic for adenomyosis, imaging uses the appearance of the myometrium, the presence of striations, related to the presence of endometrial tissue within the myometrium, the presence of intramyometrial cystic structures and the size and asymmetry of the uterus to identify adenomyosis. Preliminary reports show a good correlation between the features detected by imaging and the histological findings. Symptoms associated with adenomyosis are abnormal uterine bleeding, pelvic pain (dysmenorrhea, chronic pelvic pain, dyspareunia), and impaired reproduction. However a high incidence of existing comorbidity like fibroids and endometriosis makes it difficult to attribute a specific pathognomonic symptom to adenomyosis. Heterogeneity in the reported pregnancy rates after assisted reproduction is due to the use of different ovarian stimulation protocols and absence of a correct description of the adenomyotic pathology. Current efforts to classify the disease contributed a lot in elucidated the potential characteristics that a classification system should be relied on. The need for a comprehensive, user friendly, and clear categorization of adenomyosis including the pattern, location, histological variants, and the myometrial zone seems to be an urgent need. With the uterus as a possible unifying link between adenomyosis and endometriosis, exploration of the uterus should not only be restricted to the hysteroscopic exploration of the uterine cavity but in a fusion with ultrasound. PMID- 29566851 TI - Role of transvaginal sonography and magnetic resonance imaging in the diagnosis of uterine adenomyosis. AB - The aim of the present review, conducted according to PRISMA statement recommendations, was to evaluate the contribution of transvaginal sonography (TVS) and magnetic resonance imaging (MRI) to diagnose adenomyosis. Although there is a lack of consensus on adenomyosis classification, three subtypes are described, internal, external adenomyosis, and adenomyomas. Using TVS, whatever the subtype, pooled sensitivities, pooled specificities, and pooled positive likelihood ratios are 0.72-0.82, 0.85-0.81, and 4.67-3.7, respectively, but with a high heterogeneity between the studies. MRI has a pooled sensitivity of 0.77, specificity of 0.89, positive likelihood ratio of 6.5, and negative likelihood ratio of 0.2 for all subtypes. Our results suggest that MRI is more useful than TVS in the diagnosis of adenomyosis. Further studies are required to determine the performance of direct signs (cystic component) and indirect signs (characteristics of junctional zone) to avoid misdiagnosis of adenomyosis. PMID- 29566852 TI - Role of medical therapy in the management of uterine adenomyosis. AB - Adenomyosis is a benign uterine condition affecting women at various ages with different symptoms. The management of these patients is still controversial. Few clinical studies focusing on medical or surgical treatment for adenomyosis have been performed. No drug is currently labelled for adenomyosis and there are no specific guidelines to follow for the best management. Anyhow, medical treatments are effective in improving symptoms (pain, abnormal uterine bleeding and infertility). The rationale for using medical treatment is based on the pathogenetic mechanisms of adenomyosis: sex steroid hormones aberrations, impaired apoptosis, and increased inflammation. Several nonhormonal (i.e., nonsteroidal anti-inflammatory drugs) and hormonal treatments (i.e., progestins, oral contraceptives, gonadotropin-releasing hormone analogues) are currently used off-label to control pain symptoms and abnormal uterine bleeding in adenomyosis. Gonadotropin-releasing hormone analogues are indicated before fertility treatments to improve the chances of pregnancy in infertile women with adenomyosis. An antiproliferative and anti-inflammatory effect of progestins, such as dienogest, danazol and norethindrone acetate, suggests their use in medical management of adenomyosis mainly to control pain symptoms. On the other hand, the intrauterine device releasing levonorgestrel resulted is extremely effective in resolving abnormal uterine bleeding and reducing uterine volume in a long-term management plan. Based on new findings on pathogenetic mechanisms, new drugs are under development for the treatment of adenomyosis, such as selective progesterone receptor modulators, aromatase inhibitors, valproic acid, and anti platelets therapy. PMID- 29566853 TI - Uterine adenomyosis and adenomyoma: the surgical approach. AB - The appropriate surgical treatment of adenomyosis, a benign invasion/infiltration of endometrial glands within the underlying myometrium, remains a subject of discussion. Since 1990, in place of the classical V-shaped resection method, various kinds of surgical management have been attempted, including a uterine muscle flap method that emphasizes fertility preservation, an asymmetric dissection method, and various modified reduction methods. Laparoscopic adenomyomectomy has also become an alternative to laparotomy for surgically managing the focal type of adenomyosis, although it seems to be associated with a higher risk of uterine rupture than laparotomy. This article reviews the surgical treatment of adenomyosis, including 23 uterine rupture cases that occurred during post-adenomyomectomy pregnancies, and provides an updated picture of the state of the field.

Several studies demonstrate higher birth rates after aneuploidy testing and elective single-embryo transfer (eSET), suggesting the potential for this testing to decrease the risk of multiple gestations, though these studies have important limitations.

AB - OBJECTIVE: To evaluate prospectively the association between male sleep duration and fecundability. DESIGN: Pregnancy Online Study (PRESTO), a Web-based prospective cohort study of North American couples enrolled during the preconception period (2013-2017). SETTING: Not applicable. PATIENT(S): Male participants were aged >=21 years; female participants were aged 21-45 years. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): At enrollment, men reported their average nightly sleep duration in the previous month. Pregnancy status was updated on female follow-up questionnaires every 8 weeks for up to 12 months or until conception. Analyses were restricted to 1,176 couples who had been attempting to conceive for up to six cycles at enrollment. Proportional probabilities regression models were used to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs), adjusting for potential confounders. RESULT(S): Relative to 8 hours per night of sleep, multivariable-adjusted FRs for <6, 6, 7, and >=9 hours per night of sleep were 0.62 (95% CI 0.45-0.87), 1.06 (95% CI 0.87-1.30), 0.97 (95% CI 0.81-1.17), and 0.73 (95% CI 0.46-1.15), respectively. The association between short sleep duration (<6 hours per night) and fecundability was similar among men not working nights or rotating shifts (FR 0.60, 95% CI 0.41-0.88) and among men without a history of infertility (FR 0.62, 95% CI 0.44-0.87) and was stronger among fathers (FR 0.46, 95% CI 0.28-0.76). CONCLUSION(S): Short sleep duration in men was associated with reduced fecundability. Because male factor accounts for 50% of couple infertility, identifying modifiable determinants of infertility could provide alternatives to expensive fertility workups and treatments.

AB - INTRODUCTION AND OBJECTIVE: Auditory steady state responses to continuous amplitude modulated tones at rates between 70 and 110Hz, have been proposed as a feasible alternative to objective frequency specific audiometry in cochlear implant subjects. The aim of the present study is to obtain physiological thresholds by means of auditory steady-state response in cochlear implant patients (Clarion HiRes 90K), with acoustic stimulation, on free field conditions and to verify its biological origin. METHODS: 11 subjects comprised the sample. Four amplitude modulated tones of 500, 1000, 2000 and 4000Hz were used as stimuli, using the multiple frequency technique. The recording of auditory steady state response was also recorded at 0dB HL of intensity, non-specific stimulus and using a masking technique. RESULTS: The study enabled the electrophysiological thresholds to be obtained for each subject of the explored sample. There were no auditory steady-state responses at either 0dB or non specific stimulus recordings. It was possible to obtain the masking thresholds. A difference was identified between behavioral and electrophysiological thresholds of -6+/-16, -2+/-13, 0+/-22 and -8+/-18dB at frequencies of 500, 1000, 2000 and 4000Hz respectively. CONCLUSIONS: The auditory steady state response seems to be a suitable technique to evaluate the hearing threshold in cochlear implant subjects.

PMID- 29566903 TI - The gastrointestinal microbiota and its role in oncogenesis. AB - Advances in research techniques have made it possible to map the microbial communities in the gastrointestinal (GI) tract, where the majority of bacteria in the human body reside. Disturbances in these communities are referred to as dysbiosis and have been associated with GI cancers. Although dysbiosis is observed in several GI malignancies, the specific role of these changes has not been understood to the extent of Helicobacter pylori (HP) in gastric cancer (GC). This review will address the bacterial communities along the GI tract, from the oral cavity to the anal canal, particularly focusing on bacterial dysbiosis and carcinogenesis. Just as non-HP bacteria in the stomach may interact with HP in gastric carcinogenesis, the same may hold true for other GI tract malignancies, where an interplay between microbes in carcinogenesis seems conceivable, especially in colorectal cancer (CRC). In the last part of this review we will discuss the potential mechanisms of bacterial dysbiosis in GI carcinogenesis. PMID- 29566904 TI - Microbiome measurement: Possibilities and pitfalls. AB - Microbiome research is an emerging field in medical sciences. Several studies have made headways in understanding the influence of microbes on our health and disease states. Further progress in mapping microbiome populations across different body sites and understanding the underlying mechanisms of microbiome host interactions depends critically on study design, collection protocols, analytical genetic techniques, and reference databases. In particular, a shift has appeared going from small sample collections to large-scale population studies (with extensive phenotypic information including disease status) which calls for some adaptions. In this review we will focus on gut microbiome profiling using the 16S ribosomal RNA approach in the setting of large-scale population studies, and discuss some novel developments. PMID- 29566905 TI - Lifestyle alters GUT-bacteria function: Linking immune response and host. AB - Microbiota in human is a "mixture society" of different species (i.e. bacteria, viruses, funguses) populations with a different way of relationship classification to Human. Human GUT serves as the host of the majority of different bacterial populations (GUT flora, more than 500 species), which are with us ("from the beginning") in an innate manner known as the commensal (no harm to each other) and symbiotic (mutual benefit) relationship. A homeostatic balance of host-bacteria relationship is very important and vital for a normal health process. However, this beneficial relationship and delicate homeostatic state can be disrupted by the imbalance of microbiome-composition of gut microbiota, expressing a pathogenic state. A strict homeostatic balance of microbiome-composition strongly depends on several factors; 1- lifestyle, 2- geography, 3- ethnicities, 4- "mom" as prime of the type of bacterial colonization in infant and 5- the disease. With such diversity in individuals combined with huge number of different bacterial species and their interactions, it is wise to perform an in-depth systems biology (e.g. genomics, proteomics, glycomics, and etcetera) analysis of personalized microbiome. Only in this way, we are able to generate a map of complete GUT microbiota and, in turn, to determine its interaction with host and intra-interaction with pathogenic bacteria. A specific microbiome analysis provides us the knowledge to decipher the nature of interactions between the GUT microbiota and the host and its response to the invading bacteria in a pathogenic state. The GUT-bacteria composition is independent of geography and ethnicity but lifestyle well affects GUT-bacteria composition and function. Microbiome knowledge obtained by systems biology also helps us to change the behavior of GUT microbiota in response to the pathogenic microbes as protection. Functional microbiome changes in response to environmental factors will be discussed in this review. PMID- 29566906 TI - Action and function of Akkermansia muciniphila in microbiome ecology, health and disease. AB - The discovery of Akkermansia muciniphila has opened new avenues for the use of this abundant intestinal symbiont in next generation therapeutic products, as well as targeting microbiota dynamics. A. muciniphila is known to colonize the mucosal layer of the human intestine where it triggers both host metabolic and immune responses. A. muciniphila is particularly effective in increasing mucus thickness and increasing gut barrier function. As a result host metabolic markers ameliorate. The mechanism of host regulation is thought to involve the outer membrane composition, including the type IV pili of A. muciniphila, that directly signal to host immune receptors. At the same time the metabolic activity of A. muciniphila leads to the production of short chain fatty acids that are beneficial to the host and microbiota members. This contributes to host microbiota and microbe-microbe syntrophy The mucolytic activity and metabolite production make A. muciniphila a key species in the mucus layer, stimulating beneficial mucosal microbial networks. This well studied member of the microbiota has been studied in three aspects that will be further described in this review: i) A. muciniphila characteristics and mucin adaptation, ii) its role as key species in the mucosal microbiome, and iii) its role in host health. PMID- 29566907 TI - Action and function of Faecalibacterium prausnitzii in health and disease. AB - Faecalibacterium prausnitzii, anaerobic bacteria, is one of the main components of gut microbiota and the most important butyrate-producing bacteria in the human colon. So far, this commensal bacterium has been considered as a bioindicator of human health, once when its population is altered (decreased), inflammatory processes are favored. Several reports in the literature highlighted that the amount of Faecalibacterium prausnitzii negatively correlates to the activity of inflammatory bowel disease and colorectal cancer. Therefore, counterbalancing dysbiosis using Faecalibacterium prausnitzii as a potential active component of probiotic formulations appears to be a promising therapeutic strategy for inflammatory bowel diseases and colorectal cancer. However, once this microbial is very sensitive to oxygen, the formulation development is a great challenge. In this review, we will focus our attention on Faecalibacterium prausnitzii biology, anti-inflammatory metabolites, modulators of this bacterium population and its impact on human health. PMID- 29566908 TI - Action and function of Chromobacterium violaceum in health and disease: Violacein as a promising metabolite to counteract gastroenterological diseases. AB - Chromobacterium violaceum is a Gram negative, beta-proteobacterium found in the microbiota of tropical and subtropical environments. Although considered an opportunistic pathogen, infection rapidly progress to fatal sepsis, with metastatic abscesses. It is noteworthy the multidrug resistant phenotype of C. violaceum and the possibility of relapse. Recently, an influence of global climate in the incidence of cases beyond the previous areas has been observed. Furthermore, chronic granulomatous disease has been considered a risk factor to infection. Despite the increase in C. violaceum infection incidence and high mortality, most clinicians are not familiar with it. This review pointed out important features of this life threatening microorganism, including its pathogenicity, mechanistic aspects, genetic and drug resistance associated factors, and the clinical association with chronic granulomatous disease. In addition, its main metabolite violacein may be a promising agent to counteract gastroenterological diseases, such as colorectal cancer and inflammatory gastric lesions. PMID- 29566909 TI - NAFLD, Helicobacter species and the intestinal microbiome. AB - Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. It is well-accepted that gut dysbiosis is associated with NAFLD, however, there is some conflicting evidence regarding the nature of these alterations. Infection with Helicobacter species, mainly H. pylori, has also been associated with increased NAFLD risk, however, some studies have failed to reproduce this finding. Further studies including large study samples and standardised procedures for microbiota analyses, H. pylori detection and NAFLD diagnostic criteria, are required. The mechanisms involving Helicobacter species and the intestinal microbiome in NAFLD pathogenesis appear to be part of the multiple-hit theory, in which increased intestinal permeability, inflammatory responses, altered choline, bile acids and carbohydrate metabolism, production of short-chain fatty acids, urea cycle and urea transport systems, altered maintenance of hepatic gammadeltaT-17 cells, insulin resistance, hormones secreted by the adipose tissue, metabolic hormones, bacterial metabolites and Helicobacter toxins, are all implicated. PMID- 29566910 TI - Intestinal microbiome and permeability in patients with autoimmune hepatitis. AB - Autoimmune hepatitis (AIH) is a severe inflammatory liver disease. The underlying mechanisms remain unclear, but recent studies provided new perspectives on altered intestinal microbiome and permeability in AIH animal models and patients, highlighting gut-liver crosstalk in the pathogenesis of AIH. Transgenic AIH mice carrying HLA-DR3 showed reduced diversity and total load of gut microbiota. Germ free mice are resistant to concanavalin A-induced liver injury, whereas enterogenouss antigens induce the activation of natural killer T cells participating in concanavalin A-induced liver injury, supporting the close relationship between microbiota and AIH. Moreover, 'molecular mimicry' provides a plausible interpretation of the immune reactions between microorganic antigens and liver autoantigens, for instance, cytochrome P4502D6, the target of cross reactivity between virus and self. Nevertheless, direct evidence for the intestinal microbiome and permeability in AIH is still limited. The relationship between AIH susceptibilities and an intestinal microbiome shaped by drugs, diets or genes needs further study. PMID- 29566911 TI - Diet, microbiome, and colorectal cancer. AB - The scientific interests in the colorectal cancer (CRC) associated microbiome have increased significantly in the past decade. Mechanistically, several members of the human microbiome and products thereof have been implicated as inductors of the pathogenic inflammation related to CRC. Conversely, the activities of the human intestinal microbial community influenced by specific diet might confer a protective effect against the CRC risks and progression. As the microbiome is both a key contributor and one of the tools to prevent CRC, the current review gives a summary of the CRC-associated microbiome and the dietary strategies relevant to CRC. As more evidences become available, new microbiome-based treatments and specific diets may emerge to reduce the CRC risk and improve CRC patients' quality of life. PMID- 29566912 TI - Microbiome, pattern recognition receptor function in health and inflammation. AB - The innate immune system plays an important role in shaping the microbiota into configurations that are tolerated and beneficial to the host, thereby playing a crucial role in human health. Innate immunity is based on the fundamental principle that Pattern Recognition Receptors (PRRs) recognise pathogen associated molecular patterns as non-self-entities and trigger intracellular signalling pathways that lead to the induction of numerous cytokines and chemokines that help maintain host resistance to infections. Dysregulation of this interaction has been identified as the core defect that leads to chronic intestinal inflammation allowing certain microbiota to be harmful to host health. This dysbiosis of the microbiome is found associated with numerous chronic diseases. A logical explanation would be that genetic defects in the recognition and response pathways that the host uses to identify these microbial pathogens could lead to altered microbial colonisation or mis-recognition of normal bacteria leading to diseases. The interaction between pattern recognition receptors, microbial traits and human health with respect to the gut are now rapidly resolved and will be the subject of this review. PMID- 29566913 TI - Intervening in disease through genetically-modified bacteria. AB - The comprehension of the molecular basis of different diseases is rapidly being dissected as a consequence of advancing technology. Consequently, proteins with potential therapeutic usefulness, including cytokines and signaling molecules have been identified in the last decades. However, their clinical use is hampered by disadvantageous functional and economic considerations. One of the most important of these considerations is targeted topical delivery and also the synthesis of such proteins, which for intravenous use requires rigorous purification whereas proteins often do not withstand digestive degradation and thus cannot be applied per os. Recently, the idea of using genetically modified bacteria has emerged as an attempt to evade these important barriers. Using such bacteria can deliver therapeutic proteins or other molecules at place of disease, especially when disease is at a mucosal surface. Further, whereas intravenously applied therapeutic proteins require expensive methodology in order to become endotoxin-free, this is not necessary for local application of therapeutic proteins in the intestine. In addition, once created further propagation of genetically modified bacteria is both cheap and requires relatively little in conditioning with respect to transport of the medication, making such organisms also suitable for combating disease in developing countries with poor infrastructure. Although first human trials with such bacteria were already performed more as a decade ago, the recent revolution in our understanding of the role of human gut microbiome in health and diseases has unleashed a revolution in this field resulting in a plethora of potential novel prophylactic and therapeutic intervention against disease onset and development employing such organisms. Today, the engineering of human microbiome for health benefits and related applications now chances many aspects of biology, nanotechnology and chemistry. Here, we review genetically modified bacteria methodology as possible carriers of drug delivering and provided the origin and inspirations for new drug delivery systems. PMID- 29566914 TI - The mature patient: Geriatric dermatology. PMID- 29566915 TI - Skin barrier and dry skin in the mature patient. AB - Dry skin is the most common clinical manifestation of dermatologic diseases, and it presents with itching, redness, and desquamation-signs and clinical manifestations that are not only physically uncomfortable but also affect patients psychologically. The water content in the stratum corneum is largely dependent on the composition and amount of the intercellular lipids, which regulate the loss of water from the skin, and on the levels of hygroscopic substances of the natural moisturizing factors, which are responsible for retention of water in the stratum corneum. Prevention of water loss and penetration of potentially toxic substances and microorganisms into the body are the most important functions of the skin, which acts as a natural frontier between the inner organism and the environment. Skin barrier defects occur in several skin diseases, but the influence of aging on the skin barrier function is largely unknown and conflicting results have been reported. In this review, the structure and function of the barrier in relation to the aging process are discussed. PMID- 29566916 TI - Diagnostic challenges in the mature patient: Growing old gracefully. AB - Skin diseases in the elderly are frequent and sometimes misleading, due to age related changes that alter the clinical presentation. Clinicopathologic correlation is often the clue for distinguishing among various pathologies for which clinical signs are more striking than the histopathologic findings. Pitfalls are always lying in wait to ambush inexperienced dermatologists, but usually the microscope provides subtle hints to solve the quandary. In an attempt to familiarize physicians with emerging skin care demands of older patients, we have reviewed major diagnostic challenges in this group of patients: age-related changes, more common skin pathologies in mature patients, manifestations of comorbidity, skin tumors, and paraneoplastic syndromes. PMID- 29566917 TI - Therapeutic challenges in the mature patient. AB - With the tremendous increase in the proportion of seniors in the global population, geriatric health care has become of greater interest and concern. Increased emphasis on geriatric medicine, along with the growth in the development of age-related skin disorders, has led to particular attention for geriatric, dermatology and dermatopharmacology. An aging population has brought many therapeutic challenges that we need to recognize and overcome by applying geropharmacologic principles. The purpose of this paper is to inform dermatologists of the age-related changes in the pharmacokinetics of common dermatologic drugs, their various interactions potentially occurring in the elderly, and the principles and evidence-based strategies for detection, management, and prevention to improve medication adherence. By implementing these principles and strategies, we can ensure the best and the safest treatment to promote the desired therapeutic outcome and improved quality of life for this fragile subpopulation. PMID- 29566918 TI - Causes, pathophysiology, and treatment of pruritus in the mature patient. AB - Chronic itch is a common and debilitating health condition in the elderly. There are several common causes of itch in the mature population, such as skin xerosis, immunosenescence, and neuropathic changes. In addition, skin diseases, such as seborrheic dermatitis and stasis dermatitis, systemic conditions (end-stage renal disease and diabetes), or psychogenic derailments, such as depression, anxiety, and dementia, can all serve as triggers of pruritus. Polypharmacy, a common occurrence among the elderly population, may also serve as a cause of itch that may or may not be accompanied by dermatitis. Such medications as MU opioids and calcium channel blockers have been found to have a connection with pruritus in the advanced aging population. Determining the exact trigger for pruritus in the elderly may be especially challenging, because itch can be idiopathic in many cases. The role of treatments should not only take into account elimination of various underlying cutaneous, systemic, or psychogenic conditions associated with itch but also focus on the skin changes that are characteristic of the aging process. Development of such treatment options can be guided by elucidation of the mechanisms underlying the pathophysiology of itch in the geriatric population. PMID- 29566919 TI - Facial changes in the mature patient. AB - During the aging process, the appearance of the human face changes significantly due to fundamental alterations in the bones, soft tissues, and skin. Both endogenous and environmental factors are involved in age-related transformations of the face; however, facial skin is particularly influenced by environmental factors, and the risk of overexposure and consequent premature facial aging. This review summarizes the current state of knowledge of the most common facial skin changes in the mature patient, including pathogenesis of both intrinsic and extrinsic skin aging, as well as clinical and histologic features of skin aging. Because the majority of facial skin changes in the elderly develop as the consequence of ultraviolet radiation, these can be prevented by adequate photoprotection. PMID- 29566920 TI - Hair and nail diseases in the mature patient. AB - The elderly population is growing, lifespans are increasing, and a greater emphasis on geriatric care is being implemented in hospital systems. With a higher percentage of the population living longer, hair and nail diseases associated with the advanced stages of life are becoming more prevalent. Common hair diseases in the elderly include androgenetic alopecia, senile alopecia, frontal fibrosing alopecia, and erosive pustular dermatosis of the scalp. Nail diseases associated with advanced age include onychomycosis, brittle nails, onychocryptosis, onychoclavus, onychogryphosis, subungual hematomas, subungual exostosis, myxoid cysts, and malignancies. These diseases can have a serious impact on a patient's quality of life. In an effort to familiarize the reader with these common changes and abnormalities, we discuss hair and nail diseases in the mature patient. PMID- 29566921 TI - Epidemiology of skin cancer in the mature patient. AB - Epidermal cancers include keratinocyte cancer, melanocyte cancer, and Merkel cell carcinoma. These cancers account for the vast majority of new cancers diagnosed in Australia, North America, and Europe. Keratinocyte cancer is the most common epidermal cancer and accounts for 7 out of 8 new cancers diagnosed in Australia. Melanoma and Merkel cell carcinoma are less common than keratinocyte carcinoma but are more important causes of mortality in Australia. Keratinocyte cancer has also been demonstrated to be a marker of cancer-prone phenotype. Risk factors for epidermal cancer include intrinsic and environmental factors, in particular exposure to ultraviolet radiation and advanced age. Actinic keratosis has an approximate prevalence of 79% of men and 68% of women between 60 and 69 years of age, and has a low risk of malignant transformation into squamous cell carcinoma. Basal cell carcinoma is the most common malignancy in Caucasians worldwide, with the incidence increasing by 2% per year in Australia. Squamous cell carcinoma is the second most common epidermal cancer, with an incidence of approximately 1035 or 472 per 100,000 person-years in men and women, respectively. Primary risk factors for both basal cell carcinoma and squamous cell carcinoma include light skin color, UV radiation exposure, and chronic immunosuppression. Although the rate of melanoma is increasing, the mortality in Australia is reducing and is currently 9%. The overall incidence of melanoma in Australia is approximately 50 cases per 100,000 persons (62 for men and 40 for women). Keratinocyte carcinoma and melanoma are risk factors for developing further skin cancer and primary malignancy. This contribution reviews the incidence, prevalence, and risk factors associated with the development of epidermal cancer and premalignant epidermal neoplasia. PMID- 29566922 TI - Nonsurgical treatment of nonmelanoma skin cancer in the mature patient. AB - Nonmelanoma skin cancer (NMSC) is the most common cancer, with the median age at NMSC diagnosis is 71 years. Treatment options for NMSC include surgical therapy, which is usually the first-choice treatment, and nonsurgical modalities. Therapeutic modalities depend on tumor localization, histologic type, and biologic behavior, as well as patient comorbidities, age, and life expectancy. Nonsurgical treatments include cryotherapy, local therapies (imiquimod, 5 fluorouracil, ingenol mebutate, and diclofenac), photodynamic therapy, radiotherapy, and hedgehog inhibitors. Some of these treatments can be combined with curettage and electrodesiccation for better outcomes. Every treatment modality has advantages and disadvantages that must be carefully considered individually. Because the facial area is the most common localization of NMSC, treatment modalities with better cosmetic outcome are preferred. Although NMSC mostly occurs in the elderly, this review is focused on the features and nonsurgical therapy of NMSC in deep old age (>=85) and long-lived persons (aged >95); however, clinical trials very rarely involve this population group due to poor cooperation or poor general condition of these patients; thus, the respective knowledge being generally based on clinical experience. PMID- 29566923 TI - Cutaneous infections in the mature patient. AB - Dermatologists must be familiar with the peculiarities of the micro-organisms that may affect the elderly, in order to optimize the diagnosis and treatment of infections, which may affect their skin, especially because the world population is rapidly aging. It is estimated that there will be 434 million individuals over 80 years of age in 2050. Since the elderly population is rapidly increasing and their infections are usually more severe and different from those observed in younger adults, it leads to a statistical increase of the rates regarding hospitalization and mortality caused by infectious diseases among people over 85 years. Other health issues may be involved in the older population. These include nutritional alterations, as malnutrition or obesity, which can aggravate the infections. Also the usual signs and symptoms of infection are subtle or uncharacteristic in elderly patients, and frequently, they are unable to report their symptoms, which can delay the diagnosis. Among the many infections that may affect the elderly we reviewed the most frequent and those that are different in this age group, as herpes zoster, cytomegalovirus, herpes simplex, bacterial skin infections, erysipelas, celullitis, impetigo, folliculitis, furunculosis and carbunculosis, secondary infections, intertrigo (body folds), fungal infection, and scabies. PMID- 29566924 TI - Genital diseases in the mature man. AB - Elderly men are at higher risk of developing genital dermatologic problems, including inflammatory and neoplastic conditions due to age-related physiologic changes, immunosenescence, comorbidities, and iatrogenesis. Clinical manifestations of genital dermatoses in men are varied and may include itching, pain, redness, dermatitis, lumps, and ulcers. Even when asymptomatic, the psychologic impact may be significant. Sexual or urinary dysfunction may complicate genital dermatoses. Early and accurate diagnosis is essential to reduce morbidity and mortality from premalignant and malignant conditions and also to prevent sexual dysfunction and unnecessary anxiety in the case of benign entities. PMID- 29566925 TI - Genital diseases in the mature woman. AB - Vulvovaginal conditions are common in mature women. This reflects age-related changes in immunity and skin barrier function of vulvovaginal tissues. Vaginal atrophy is commonly complicated by dryness and inflammation, which makes postmenopausal atrophic vaginitis a virtually ubiquitous condition. The differential of vaginitis includes inflammatory, infectious, and malignant diseases, plus drug hypersensitivity. Atrophic vaginitis is treated with estrogen replacement therapy. Vulvovaginal malignant melanoma occurs predominantly in postmenopausal women and carries a poor prognosis. Similarly, the incidence of vulvovaginal malignancies, such as squamous cell carcinoma and extramammary Paget disease, rises exponentially after 65 years of age. Early diagnosis of these malignancies is of utmost importance. Lichen sclerosus et atrophicus and vulvovaginal candidosis are among the most common postmenopausal vulvovaginal conditions. Lichen sclerosus et atrophicus is associated with significant morbidity, and its management can be challenging. The incidence of vulvovaginal candidosis increases in patients on estrogen replacement therapy. PMID- 29566926 TI - Psoriasis in the mature patient: Therapeutic approach in the era of biologics. AB - Management of psoriasis in elderly patients may be challenging due to a small number of studies investigating this specific population. When treating a mature patient, special consideration should be given to multiple comorbidities, progressive functional impairment of several organs, immunosenescence, possible adverse effects, and polypharmacy. Due to the chronic nature of the disease and continuing rise in life expectancy, the prevalence of psoriasis among elderly is also expected to rise. Because many different therapies are available for treatment of psoriasis, we have reviewed those that have been investigated in the aging population. Although biologics have revolutionized the therapy of psoriasis due to targeted mechanism of action, high efficacy and low rate of adverse events, studies on the elderly population with psoriasis are scarce. Further clinical research and development of specific treatment guidelines in geriatric population are needed to optimize the therapeutic approach in this population. PMID- 29566927 TI - Blistering diseases in the mature patient. AB - Autoimmune blistering diseases (AIBD) are a group of chronic diseases affecting the skin and mucous membranes, with different presentation, clinical course, histologic and immunopathologic findings, and different therapeutic approach. Blisters develop as a result of autoantibodies directed against distinct adhesion structures within desmosomes or within the basement membrane zone. The most common AIBD that develops in the elderly is bullous pemphigoid (previously also named "pemphigoid senilis"), but mature patients can also present with other AIBD as mucous membrane pemphigoid, epidermolysis bullosa acquisita, paraneoplastic pemphigus, pemphigus vulgaris, pemphigus foliaceus, linear IgA dermatosis, and dermatitis herpetiformis. There are no differences in treatment approach to mature patients with AIBD, but due to more common comorbidities, systemic therapy should be given with more caution and control, and due to distorted skin integrity in the aged skin, the safety concerns are increased with the long-term use of any topical medication. PMID- 29566928 TI - Vascular diseases in the mature patient. AB - Aging results in both anatomic and physiologic changes in the skin's structure and vascular system. These vascular changes result in a wide array of dermatologic findings, ranging from the benign to the highly morbid. Herein, we review the impact of both intrinsic and common extrinsic factors of aging on cutaneous vasculature and highlight the manifestations of microvascular, venous, arterial, lymphatic, and neuropathic alterations in the geriatric population. PMID- 29566929 TI - Drug eruptions in the mature patient. AB - The world's population is now ageing at an unprecedented rate. Declining fertility and improved health and longevity have generated rising numbers and proportions of the older population in most parts of the world. With advancing age, however, comes an increasing incidence of disease (comorbidity or multimorbidity), an increasing use of medications (polypharmacy), and consequently an increase in adverse drug reactions (ADRs). Age-related changes in pharmacodynamics and pharmacokinetics (eg, volumes of drug distribution, metabolism and clearance, altered drug responsiveness and toxicity) and greater vulnerability to ADRs are other reasons for the higher incidence of ADRs in the elderly compared with young adults. Because the clinical patterns of ADRs are very similar for all age groups, including the elderly, the present review will deal mainly with statistics and numbers, rather than the clinical and/or disease patterns. PMID- 29566930 TI - Chronic immunosuppression in the mature patient. AB - In the ever-aging population of the world, the field of geriatrics continues to grow in importance. As human beings age, the skin undergoes a unique array of changes that predispose it to a specific set of dermatoses, infections, and neoplasms. Some of these physiologic alterations are comparable to the changes that happen in immunosuppressed individuals. Given the importance of immunosuppressive medications in treatment of many common skin conditions, we have reviewed the current literature to assist the practicing clinician in using immunosuppressive medications in the geriatric population. PMID- 29566931 TI - Signs of physical abuse and neglect in the mature patient. AB - Neglect and physical abuse of elderly are worrisome health problems, which are expected to grow even further, considering the aging of the population. By 2060, the number of people aged above 65 years is expected to double, whereas birth rates are low. This trend will cause a significant imbalance between different age groups and put more senior adults at risk for abuse. Risk factors, associated with abuse and neglect, are well established and can be categorized in sociodemographic-, victim-, or perpetrator-related risk factors. The effects of these risk factors depend mainly on the setting, which can be community-dwelling or institutionalized older adults. In community-based settings, 90% of perpetrators are family members. In each setting, suspicious physical injuries should be recognized and addressed promptly. This can be very challenging in elderly, among others, due to the age-related skin changes, which can mimic abuse; however, there are some cutaneous clues that should always raise suspicion of abuse, such as patterned shape or distribution, different healing stages of wounds, parallel injuries, signs of blunt trauma, and irregular patches of alopecia. General awareness is needed, and the advice of dermatologists, who are best trained to differentiate between those lesions, should be systematically sought, to reduce false-positive and false-negative interpretations. PMID- 29566932 TI - The status of the seborrheic keratosis. AB - Seborrheic keratosis (SK), whose appearance is generally a small roundish reddish to brownish scaling lesion ranging in size from a few mm to many mm, may have a single presentation or be one of many such lesions. Because it is a commonly encountered lesion on the face, trunk, or extemities and is readily recognized clinically, it is infrequently biopsied. When the lesion has an unusual pattern or has become irritated, it may rarely mimic a malignancy,Most patients ignore such common age spots; however, others may have concern about their appearence, in which case the SKs have been surgicaly excised. In recent retrospective studies and case reports, SKs have rarely been found to have malignant characteristics. Although these studies are inconclusive, lesions that are inflamed, bleeding, ulcerated, or sufficiently irritated may require being biopsied to rule out melanoma or other malignancies.

PMID- 29566934 TI - Comparison of two dosing methods for immediate administration of tolvaptan in acute decompensated heart failure. AB - BACKGROUND: The clinical dosing method for tolvaptan in patients with acute heart failure (HF) is still unclear. We aimed to compare the differences in clinical effect between two dosing regimens: once-daily 7.5mg and twice-daily 3.75mg. METHODS: In this randomized trial, tolvaptan was administered within 12h from hospital admission. The primary outcome was the serial change in congestion scores measured every day from enrollment until dosing day 7. Outcomes including safety parameters were also evaluated. RESULTS: The subjects were assigned to either the once-daily 7.5mg dosing regimen (N=15) or the twice-daily 3.75mg dosing regimen (N=16). The time-course changes in body weight, serum sodium and creatinine levels, systolic blood pressure, daily urine output, and congestion scores were similar between the two groups. In the twice-daily 3.75mg dosing group, the serum sodium levels on days 3 and 4 were significantly (p<0.05) increased compared with those on day 1. The congestion scores significantly (p<0.05) decreased from day 2 to day 7 in both groups compared with those on day 1. However, the difference in the serial change in the congestion scores did not reach statistical significance. CONCLUSIONS: Our present results suggest that the early administration of tolvaptan within 12h after hospital admission significantly improved congestion from the first day after administration by either dosing regimen, i.e. once-daily 7.5mg or twice-daily 3.75mg in patients with acute HF.

PMID- 29566938 TI - Reducing waste in pediatric clinical research. AB - The importance of reducing waste and increasing value when conducting research has been emphasized by a series of articles published in the Lancet in 2014. A survey indicates that, one year later, these articles have not influenced how research is conducted. In this review, we explore four stages described by Moher et al. in research production that lead to waste. We show that all four stages including, questions relevant to users, appropriate design conduct and analysis, accessible full research, unbiased and usable reports, efficient research regulation and management of biomedical research are also producing an important waste in pediatric research. We conclude that methods to improve research quality and limit waste need to be implemented in pediatric research and recognized by authorities as a priority. PMID- 29566939 TI - [Bilateral mandibular nerve injury following mask ventilation: a case report]. AB - BACKGROUND AND OBJECTIVES: Nerve injury following mask ventilation is a rare but serious anesthetic complication. The majority of reported cases are associated with excessive pressure applied to the face mask, long duration of mask ventilation, excessive digital pressure behind the mandible to relieve airway obstruction and pressure exerted by the plastic oropharyngeal airway. CASE REPORT: We present a case of bilateral mandibular nerve injury following mask ventilation with short duration, most likely due to a semi-silicone facemask with an over-inflated cushion. CONCLUSION: An over-inflated sealing cushion of a facemask may trigger difficult mask ventilation leading to mandibular nerve injury following mask ventilation. Alternative airway management techniques such as laryngeal mask airway should be considered when airway maintenance can only be achieved with strong pressure applied to the facemask and/or mandible. PMID- 29566940 TI - Breast carcinoma with osteoclast-like giant cells: A cytological-pathological correlation with a literature review. AB - Breast carcinoma with osteoclast-like giant cells (OGCs) is a rare disease characterized by the infiltration of OGCs in the tumor; however, cytological aspects of this tumor type remain elusive. We examined the cytological features in fine needle aspiration (FNA) biopsy smears obtained from 5 patients who were histologically diagnosed with breast carcinoma with OGCs. We compared FNA and clinicopathological findings with results from the published literature. Histological assessment of the resected samples showed that all tumors exhibited a histological grade 1 phenotype with a predominant cribriform architecture. Four patients were estrogen receptor positive, and 1 patient showed a triple negative phenotype. All patients survived without tumor recurrence. In the FNA smears, tumor cells were arranged in loosely cohesive clusters, characterized by varying degrees of OGCs infiltration and rare formation of solid tumor nests. Occasionally, 2- or 3-dimensional clusters of tumor cells were found, accompanied by OGCs at the peripheral regions. In all patients, tumor cells were small without severe nuclear atypia. None of the patients showed significant background necrosis. In summary, cytological features of breast carcinoma with OGCs are characterized by loose aggregates of low grade tumor cells, the presence of OGCs, and the absence of necrosis, all of which were consistent with features reported previously. This peculiar form of breast tumors should be included in the differential diagnosis, when physicians encounter FNA findings including low grade ductal carcinoma with the admixture of multinucleated giant cells or OGCs. PMID- 29566941 TI - Peroxisome proliferator-activated receptor gamma coactivator-1alpha is a predictor of lymph node metastasis and poor prognosis in human colorectal cancer. AB - Peroxisome proliferator-activated receptor gamma (PPARgamma) and PPARgamma coactivator-1alpha (PGC-1alpha) expression levels are correlated with clinical outcome in breast cancer. However, the potential biological and clinical significance of PPARgamma and PGC-1alpha in colorectal cancer remains unknown. Here we investigated PPARgamma and PGC-1alpha expression in colorectal cancer, and the associations of these expression levels with clinicopathological features. We also evaluated the roles of PPARgamma and PGC-1alpha as prognostic factors in colorectal cancer. We performed immunohistochemical analysis to investigate PPARgamma and PGC-1alpha expression in human colorectal cancer tissues and adjacent normal tissues from 108 primary colorectal cancer patients. We then examined how these expression levels correlated with clinicopathological features. Using the Kaplan-Meier method, we evaluated 3-year disease-free survival (DFS) and overall survival (OS) in patients with tumors expressing different levels of PPARgamma and PGC-1alpha. Our results revealed that PPARgamma expression was not significantly correlated with age at surgery, gender, differentiation, depth of infiltration, relapse, or TNM stage. Additionally, PGC 1alpha expression was not significantly correlated with age at surgery, differentiation, depth of infiltration, relapse, or TNM stage. However, PGC 1alpha expression was significantly correlated with nodal metastasis (p=0.020). Survival analysis demonstrated reduced OS in the PGC-1alpha-positive group compared to the PGC-1alpha-negative group (p=0.03). Our present findings suggest that PGC-1alpha may be useful for predicting nodal metastasis, and may represent a biomarker for poor prognosis in colorectal cancer.

PMID- 29566943 TI - P16 is a useful supplemental diagnostic marker of pulmonary small cell carcinoma in small biopsies and cytology specimens. AB - Pulmonary small cell carcinoma (SCLC) is usually diagnosed in small biopsy or cytological specimens based on cytomorphology; however in ambiguous cases diagnosis requires additional support by immunohistochemistry. While TP53 and RB1 alterations with secondary overexpression of p16 are mainstay events in SCLC pathogenesis, diagnostic value of p16-positivity in the diagnosis of SCLC has not yet been fully investigated. We examined the expression of p16, CD56, synaptophysin (SYP), chromogranin A and thyroid transcription factor-1 (TTF1) in a series of pulmonary and extrapulmonary small cell carcinomas, pulmonary carcinoids and non-small cell lung carcinomas, and compared diagnostic performance of these markers in the diagnosis of SCLC. P16 was positive in 95 of 101 SCLCs, and displayed highest diagnostic sensitivity of ~94%. Composite biomarkers CD56+p16+TTF1 and CD56+p16+SYP were both able to detect correctly all SCLC cases. Importantly, three (~3%) SCLC cases completely negative for all conventional markers displayed diffuse positivity for p16. CD56 and p16 demonstrated highest concordance between paired small biopsy and cytology specimens. 50% of squamous cell carcinomas, ~41% of adenocarcinoma/NSCLC-favour adenocarcinoma cases, and ~93% of extrapulmonary small cell carcinomas also showed p16-positivity. Combination of CD56, p16 and TTF1 produced diagnostic classifier that outperformed best single marker CD56 in differential diagnosis between SCLC and NSCLC. In conclusion, in the appropriate morphological context p16 represents a useful supplementary marker for diagnosis of SCLC, even in cases where only cytological material is available. PMID- 29566944 TI - Hodgkin lymphoma with an interfollicular growth pattern: A clinicopathologic study of 8 cases. AB - Classic Hodgkin lymphoma (CHL) has four subtypes. Different morphologic variations can be seen in lymph nodes involved by CHL. Primary interfollicular (IF) involvement is not considered a separate subtype but an unusual diagnostically challenging morphologic variant. Our aim was to study the prevalence of IF growth pattern and coexistence of other morphologic variants in lymph nodes involved by CHL, to investigate the diagnostic challenges and clinical importance of this growth pattern, and to find helpful histologic clues in cases with subtle morphologic features to help avoid misinterpretation and missed diagnosis. We performed a retrospective review study over 10years. We searched for diagnosed cases of nodal CHL. We retrieved and reviewed cases of CHL with IF involvement. The clinical and pathologic features of each case were collected and compared. We found 103 cases of CHLs. Eight cases (7.8%) demonstrated IF growth patterns. The age range was between 3 and 48years with an average age of 26years. The male to female ratio was 7:1. Six cases were mixed cellularity HLs. Three cases had associated epithelioid granulomas, one had follicular involvement and one had an associated. HHV-8 negative plasma cell rich Castleman disease. One case was initially missed as benign follicular hyperplasia, one case was referred as CD and three cases were initially suspected as HL. IF growth pattern in nodal CHLs can be missed because it can be mild and focal with subtle morphologic features. The presence of epithelioid histiocytes, eosinophils and other coexistent morphologic variants are helpful histologic clues. In doubtful cases, immunohistochemistry study is essential. The majority were early stage cervical node MCHLs in young adults and children. Pathologists should be aware of this possibility when examining reactive lymph nodes. The clinical significance is limited and needs further validation by larger studies. PMID- 29566945 TI - Intra-surgical total and re-constructible pathological prostate examination for safer margins and nerve preservation (Istanbul preserve). AB - PURPOSE: To demonstrate a novel frozen section analysis technique during robot assisted radical prostatectomy with 2 distinct advantages: evaluation of the entire circumference and easier reconstruction for whole mount evaluation. MATERIAL AND METHODS: Istanbul Preserve was performed on patients who underwent robotic prostatectomy with nerve sparing between 10/2014 and 7/2016. Gland was sectioned at 3-4mm intervals from apex to bladder neck. Entire tissue representing margins (except for the most anterior portion) was circumferentially excised and microscopically analyzed. In margin positivity, approach was individualized based on extent of positive margin and Gleason pattern. A matched cohort was established for comparison. Retrospective analysis of a prospectively maintained database was performed. Impact of FSA on PSM rate was primarily assessed. RESULTS: Data on 170 patients was analyzed. Positive surgical margin was reported in 56(33%) on frozen section. Neurovascular bundle was partially or totally resected in 79% and 18%. Conversion of positive margin to negative was achieved in 85%. Overall positive margin rate decreased from 22.5% to 7.5%. Nerve sparing increased from 87% to 93%. Location of positive margin at frozen was at the neurovascular bundle area in 39%; thus Istanbul Preserve detected 61% additional margin positivity compared to other techniques. Reconstruction for whole mount was easy. CONCLUSION: Istanbul Preserve is a novel technique for intraoperative FSA during RARP allowing for microscopic examination of the entire prostate for margin status and easy re-construction for whole mount examination. It guarantees safer margins together with increased rate of nerve sparing. PMID- 29566946 TI - High cytoplasmic HuR expression is associated with advanced pT stage, high grade and increased microvessel density in urothelial bladder carcinoma. AB - PURPOSE: HuR (human antigen R) protein is a RNA binding protein that stabilizes the mRNA and controls the translation of genes involved in cell proliferation, differentiation, and carcinogenesis. Overexpression of HuR was reported in a variety of cancers, however its clinical significance in urothelial bladder cancer (UBC) is still unknown. Our aim is to investigate the association between HuR expression and selected histopathological factors, such as tumor grade, pT stage, regional lymph nodes status and microvessel density (MVD). METHODS: We studied expression of HuR protein in 119 patients with UBC in stages pTis and pTa pT4 using immunohistochemistry (IHC). Tumor MVD was evaluated immunohistochemically using anti-CD31 antibody. RESULTS: We observed no association between nuclear HuR immunoreactivity and tumor grade, stage or MVD. We found a significant association between cytoplasmic HuR positivity and high tumor grade, pT stage and MVD (p<0,001). We also observed significantly higher MVD values in cases with positive cytoplasmic HuR expression (p<0,001). No association between HuR immunoreactivity and lymph nodes status was found. CONCLUSIONS: Our results may suggest that HuR is involved in the process of acquiring malignant histopathological features and ability to invade the muscularis propria by UBC cells. Considering frequent difficulties in diagnosing UBC in specimens obtained from transurethral tumor resection and the risk of understaging, cytoplasmic HuR expression would suggest an advanced disease and necessitate serial sectioning of the specimen in search of muscle invasion. Association between HuR expression and MVD could suggest HuR involvement in the process of angiogenesis in UBC. PMID- 29566947 TI - Intraoperative sentinel lymph node evaluation: Optimizing surgical pathology practices in an era of changing clinical management. AB - Axillary lymph node status is an independent prognostic indicator in breast cancer. Intraoperative identification of metastatic carcinoma in sentinel lymph nodes may allow for concurrent axillary lymph node dissection at the time of primary tumor excision. A retrospective review of patients undergoing primary breast cancer excision with sentinel lymph node sampling was performed. Sensitivity and specificity of imprint cytology (touch prep) with and without the incorporation of gross evaluation was determined using permanent section results as the gold standard. Five hundred sixteen lymph nodes were analyzed by imprint cytology in 213 patients, and 203 lymph nodes were analyzed in 74 patients incorporating gross examination. Sensitivity and specificity for the detection of macrometastases by touch prep alone were 60% and 99% respectively with 4 patients undergoing same-day axillary dissection for only micrometastatic disease. False negative causes included lack of transfer of malignant cells in 8 cases and misinterpretation of tumor cells in 6 cases. Incorporating gross examination in the modified protocol resulted in reduced sensitivity of 38%, but achieved the desired 100% specificity and positive predictive value. Imprint cytology alone did not reliably distinguish between micro- and macrometastatic disease. Gross assessment combined with imprint cytology allows for improved assessment of volume of axillary disease, but is an insensitive technique.

PMID- 29566949 TI - Secretory carcinoma of the parotid with adenoid cystic carcinoma cytological pattern: A cytological-pathological correlation with literature review. AB - Secretory carcinoma (SC) is a rare low-grade malignant tumor, defined by ETV6 NTRK3 fusion, identifiable by FISH. We describe a case in a 58-year-old male with a painless slowly growing 16mm palpable mass within left superficial parotid. FNA of the mass showed highly cellular specimen with moderate to large pleomorphic cells with round to ovoid nuclei with vesicular chromatin and distinct nucleoli. Cells had moderate to large amounts of vacuolated cytoplasm. Abundant globular metachromatic material, resembling that of adenoid cystic carcinoma, was noted. This material was seen extracellularly and intracytoplasmic, and stained magenta on Diff-Quik and blue-green on Papanicolaou-stained slides. The tumor cells on a cell block preparation were positive for Mammaglobin and S-100. PAS stain highlighted extracellular and intracytoplasmic secretions. FNA diagnosis was "Positive for Malignancy. Morphologic features most compatible with Mammary Analogue Secretory Carcinoma". ETV6 FISH studies as well as histologic examination of excised tumor confirmed the diagnosis. Finding the globular metachromatic material in SC, that is generally seen in adenoid cystic carcinoma, broadens a cytological differential diagnosis of both entities. Cytological differential diagnosis, clinical, histological, immunohistochemical, and molecular features of secretory carcinomas are discussed in this study. PMID- 29566950 TI - Biphenotypic sinonasal sarcoma: A series of six cases with evaluation of role of beta-catenin immunohistochemistry in differential diagnosis. AB - INTRODUCTION: Biphenotypic sinonasal sarcoma (BSNS) is a recently described mesenchymal tumor exclusive to the sinonasal region. It is a low grade sarcoma, displaying evidence of myogenic and neural differentiation. Role of beta-catenin immunohistochemistry in distinguishing it from its morphological mimics is not well-established. We conducted this study to identify cases of BSNS from our archives, and to examine immunopositivity for beta-catenin in them as well as in its close differential diagnosis. METHODS: All cases of nasal cavity and paranasal sinus mesenchymal neoplasms were identified. Histopathological features were reviewed. Cases showing smooth muscle actin (SMA) and S-100 immunopositivity, and typical morphology were reclassified as BSNS. beta-catenin immunoexpression was assessed. RESULTS: Twenty-one mesenchymal tumors, including 12 sinonasal hemangiopericytoma (SNHPC), five solitary fibrous tumors (SFT), three BSNS, and one synovial sarcoma were identified. Three SNHPC cases were reclassified as BSNS. BSNS patients included one male and five females, with mean age of 51years. Five BSNS cases (83.3%) showed nuclear beta-catenin immunopositivity. SNHPC cases also were beta-catenin positive (60%). CONCLUSION: BSNS is a rare sinonasal neoplasm, frequently misdiagnosed as SNHPC and SFT. beta catenin immunopositivity is seen in majority of cases, indicating a role in pathogenesis. However, due to positivity in other tumors like SNHPC, it has limited role in differential diagnosis. PMID- 29566951 TI - Composition of the immune microenvironment differs between carcinomas metastatic to the lungs and primary lung carcinomas. AB - Lungs are among the most common sites for development of both primary and metastatic carcinomas. Tumor cells expression (TC) of PD-L1 is an important predictor of the of response to immune check-point inhibition in NSCLC, while the composition of the immune cells (IC) in the tumor microenvironment including PD L1+ cells is believed to predict responses in tumors of some other primary sites. Total mutational load (TML) and microsatellite instability (MSI) also play a role in response to the immune checkpoint blockade. We investigated immune microenvironment characteristics (PD-1, PD-L1, CD8) of 257 lung biopsies including 81 primary (NSCLC) and 176 metastatic tumors to the lungs. TML and MSI were calculated from massively parallel sequencing (592-gene panel). TC expression of PD-L1 was more common in NSCLC than in metastatic carcinomas (28% vs. 10%, p=0.009), while PD-L1-positive IC were present at relevant percentages (1-5%) exclusively in metastatic carcinomas (31% IC positive vs. 0%, p<0.001). Metastatic carcinomas carried significantly lower TML in comparison with the NSCLCs (6.6 mutations on average vs. 10, p=0.01). All primary NSCLC were microsatellite stable, and only 2 metastatic carcinomas exhibited MSI-H status. The number of PD-1+ and CD8+ tumor infiltrating lymphocytes did not differ significantly between the primary and metastatic carcinomas. Our study revealed significant differences in tumor immune microenvironment (PD-L1 in IC and TC), and its relationship to TML between NSCLC and metastatic cancers. These differences could determine the choice of a predictive biomarker test and subsequently effect(s) of the immune therapy treatments in various advanced cancers.

PMID- 29566954 TI - Skin-reducing oncoplasty: A new concept and classification in breast cancer surgery. AB - BACKGROUND AND OBJECTIVES: Breast-conserving surgery and skin-sparing mastectomy are nowadays widely accepted as the standard of care in selected patients with early breast cancer. After an accurate review of the literature, it appeared that no ordered list of the numerous techniques described for conservative breast surgery has been established so far. The aim of this study was to develop a simple classification of the different skin incision patterns that may be used in breast surgery. METHODS: A systematic review of the English literature was conducted using the PubMed database to identify all the articles reporting breast conserving surgery and skin-sparring mastectomy techniques up to the 31st of December 2016. RESULTS: Among the 1426 titles identified, 230 were selected for review. Based on the reviewed papers, the skin-reducing oncoplasty incision pattern (SROIP) classification was elaborated. CONCLUSIONS: Breast cancer surgery should nowadays optimise aesthetic outcomes by improving the final breast shape, volume and scar location. This may be achieved using different procedures that we grouped together under the term skin-reducing oncoplasty (SRO). Depending on the breast cancer location, the SROIP classification helps in the choice of the best technique to be used. PMID- 29566955 TI - [Paracommissural cleft of the lower lip: Therapeutic strategy]. AB - We report the first case described in the literature of lateral, paracommissural cleft of the lower lip in a 2-year-old child. This anomaly caused labial incompetence requiring surgical correction. Different surgical techniques have been described for the treatment of the cleft of the upper lip. We studied each of them, analyzed the advantages and disadvantages of these techniques by inverting them and adapting them for the lower lip. We opted for the double "Z" plasty of Malek because the difference in height between the cleft side and the healthy side was important. In addition, this plasty hides part of the scar in the labiomental groove. The functional and aesthetic result at 6 months after surgery is satisfactory. PMID- 29566956 TI - Transcultural adaptation and psychometric properties of Spanish version of Pregnancy Physical Activity Questionnaire: the PregnActive project. AB - OBJECTIVE: To transculturally adapt the Spanish version of Pregnancy Physical Activity Questionnaire (PPAQ) analyzing its psychometric properties. METHODS: The PPAQ was transculturally adapted into Spanish. Test-retest reliability was evaluated in a subsample of 109 pregnant women. The validity was evaluated in a sample of 208 pregnant women who answered the questionnaire and wore the multi sensor monitor for 7 valid days. The reliability (intraclass correlation coefficient), concordance (concordance correlation coefficient), correlation (Pearson correlation coefficient), agreement (Bland-Altman plots) and relative activity levels (Jonckheere-Terpstra test) between both administrations and methods were examined. RESULTS: Intraclass correlation coefficients between both administrations were good for all categories except transportation. A low but significant correlation was found for total activity (light and above) whereas no correlation was found for other intensities between both methods. Relative activity levels analysis showed a significant linear trend for increased total activity between both methods. CONCLUSIONS: Spanish version of PPAQ is a brief and easily interpretable questionnaire with good reliability and ability to rank individuals, and poor validity compared with multi-sensor monitor. The use of PPAQ provides information of pregnancy-specific activities in order to establish physical activity levels of pregnant women and adapt health promotion interventions. PMID- 29566957 TI - Negative Multiparametric Magnetic Resonance Imaging for Prostate Cancer: What's Next? AB - BACKGROUND: Multiparametric magnetic resonance imaging (mpMRI) of the prostate has excellent sensitivity in detecting clinically significant prostate cancer (csPCa). Nevertheless, the clinical utility of negative mpMRI (nMRI) is less clear. OBJECTIVE: To assess outcomes of men with nMRI and clinical follow-up after 7 yr of activity at a reference center. DESIGN, SETTING, AND PARTICIPANTS: All mpMRI performed from January 2010 to May 2015 were reviewed. We selected all patients with nMRI and divided them in group A (naive patients) and group B (previous negative biopsy). All patients without a diagnosis of PCa had a minimum follow-up of 2 yr and at least two consecutive nMRI. Patients with positive mpMRI were also identified to assess their biopsy outcomes. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A Kaplan-Meier analysis was performed to assess both any grade PCa and csPCa diagnosis-free survival probabilities. Univariable and multivariable Cox regression models were fitted to identify predictors of csPCa diagnosis. RESULTS AND LIMITATIONS: We identified 1545 men with nMRI, and 1255 of them satisfied the inclusion criteria; 659 belonged to group A and 596 to group B. Any-grade PCa and csPCa diagnosis-free survival probabilities after 2 yr of follow-up were 94% and 95%, respectively, in group A; in group B, they were 96%. After 48 mo of follow-up, any-grade PCa diagnosis-free survival probability was 84% in group A and 96% in group B (log rank p<0.001). Diagnosis-free survival probability for csPCa was unchanged after 48 mo of follow-up. On multivariable Cox regression analysis, increasing age (p=0.005) was an independent predictor of lower csPCa diagnosis probability, while increasing prostate-specific antigen (PSA) and PSA density (<0.001) independently predicted higher csPCa diagnosis probability. The prevalence of and positive predictive value for csPCa were 31.6% and 45.5%, respectively. Limitations include limited follow-up and the inability to calculate true csPCa prevalence in the study population. CONCLUSIONS: mpMRI is highly reliable to exclude csPCa. Nevertheless, systematic biopsy should be recommended even after nMRI, especially in younger patients with high or raising PSA levels. PATIENT SUMMARY: It is a matter of debate whether patients with negative multiparametric magnetic resonance imaging (mpMRI) of the prostate could obviate the need to perform a systematic biopsy. In this report, we looked at the outcomes of patients with negative mpMRI and midterm clinical follow-up at a reference center. We found mpMRI to be highly reliable to exclude significant prostate cancer; nonetheless, systematic biopsy must still be recommended after negative mpMRI in patients with high clinical suspicion of prostate cancer.

PMID- 29566959 TI - Impact of missing data strategies in studies of parental employment and health: Missing items, missing waves, and missing mothers. AB - BACKGROUND: Understanding the long-term health effects of employment - a major social determinant - on population health is best understood via longitudinal cohort studies, yet missing data (attrition, item non-response) remain a ubiquitous challenge. Additionally, and unique to the work-family context, is the intermittent participation of parents, particularly mothers, in employment, yielding 'incomplete' data. Missing data are patterned by gender and social circumstances, and the extent and nature of resulting biases are unknown. METHOD: This study investigates how estimates of the association between work-family conflict and mental health depend on the use of four different approaches to missing data treatment, each of which allows for progressive inclusion of more cases in the analyses. We used 5 waves of data from 4983 mothers participating in the Longitudinal Study of Australian Children. RESULTS: Only 23% had completely observed work-family conflict data across all waves. Participants with and without missing data differed such that complete cases were the most advantaged group. Comparison of the missing data treatments indicate the expected narrowing of confidence intervals when more sample were included. However, impact on the estimated strength of association varied by level of exposure: At the lower levels of work-family conflict, estimates strengthened (were larger); at higher levels they weakened (were smaller). CONCLUSIONS: Our results suggest that inadequate handling of missing data in extant longitudinal studies of work-family conflict and mental health may have misestimated the adverse effects of work family conflict, particularly for mothers. Considerable caution should be exercised in interpreting analyses that fail to explore and account for biases arising from missing data. PMID- 29566960 TI - Relationship transitions and change in health behavior: A four-phase, twelve-year longitudinal study. AB - RATIONALE: Extensive scientific evidence shows an association between involvement in social relationships and healthy lifestyle. Prospective studies with many participants and long follow-ups are needed to study the dynamics and change in social factors within individuals over time. OBJECTIVE: Our aim was to determine whether a change in relationship status (single, married, divorced, widow, cohabiting) is followed by a change in health behavior (smoking, alcohol consumption, physical activity, and body mass index). METHODS: We used data from 81,925 healthy adults participating in the prospective longitudinal Finnish Public Sector Study in the period 2000-2013. We analyzed 327,700 person observations from four data collection phases. Missing data were multiply imputed. A within-individual methodology was used to minimize the possibility of selection effects affecting the interpretation. RESULTS: All four health behaviors showed associations with relationship status. The effects were very similar and in the same direction in women and men, although there were gender differences in the magnitudes of the effects. The end of a relationship was followed by a decrease in body mass index, increased odds of being a smoker, increase in physical activity, and increase in alcohol consumption (widowed men). The effects were reverse when forming a new relationship. CONCLUSION: A change in relationship status is associated with a change in health behavior. The association is not explained by socioeconomic status, subjective health status, or anxiety level. People leaving or losing a relationship are at increased risk of unhealthy behavior (smoking and alcohol consumption), but at the same time they have a lower BMI and show higher physical activity compared to the time they were in a relationship. It is not clear if the cumulative health effect of these health behavior changes is positive or negative. PMID- 29566961 TI - Diagnosis and treatment of 34 cases of congenital tracheobronchial cartilage remnants of esophagus. AB - PURPOSE: To describe the diagnosis and treatment of 34 cases of congenital tracheobronchial cartilage remnants of esophagus. METHODS: The diagnosis and treatment of 34 cases of congenital tracheobronchial cartilage remnants of esophagus were analyzed retrospectively in our hospital. RESULTS: Congenital tracheobronchial cartilage remnants of esophagus could be specifically diagnosed by clinical situation and esophageal barium meal examination. The anterior wall of the esophagus was cut longitudinally with the posterior wall of the esophagus preserved. And the cartilage was removed and the open anterior wall of the esophagus was sutured horizontally with full layer. In our study, 34 patients who underwent the operation had a satisfactory outcome. However, one patient underwent submucosal cartilage stripping, which resulted in a complication involving fistulae from the esophagus to the abdominal cavity that were healed after gastrostomy and nutritional support. CONCLUSION: Congenital tracheobronchial cartilage remnants of esophagus caused symptoms when the infants were started on adjunct foods. Vomiting the food without gastric fluid and bile was the leading clinical manifestation. Distinguishing signs on esophageal barium contrast could be used as preoperative diagnosis evidence. Surgically removing the cartilage and horizontally suturing the esophagus provides a reliable outcome. LEVEL OF EVIDENCE: Level IV. TYPE OF STUDY: Retrospective study. PMID- 29566962 TI - Norton scale and vital prognosis. PMID- 29566963 TI - Analysis of the relationship between interleukin polymorphisms within miRNA binding regions and alcoholic liver disease. AB - INTRODUCTION: Alcohol consumption promotes inflammation through the Toll-like receptor 4 (TLR4)/nuclear factor (NF)-?B pathway, leading to organic damage. Some micro-RNA (miRNA) molecules modulate this inflammatory response by downregulating TLR4/NF-?B pathway mediators, like interleukins (ILs). Thus, polymorphisms within IL genes located near miRNA binding sites could modify the risk of ethanol induced damage. The present study analyzed potential relationships between alcoholism or alcoholic liver disease (ALD) and IL12B 2124 G>T (rs1368439), IL16 5000 C>T (rs1131445), IL1R1 3114 C>T (rs3917328), and NFKB1 3400 A>G (rs4648143) polymorphisms. PATIENTS AND METHODS: The study included 301 male alcoholic patients and 156 male healthy volunteers. Polymorphisms were genotyped using TaqMan(r) PCR assays for allelic discrimination. Allele and genotype frequencies were compared between groups. Logistic regression analysis was performed to analyze the inheritance model. RESULTS: Analysis of the IL1R1 (rs3917328) polymorphism showed that the proportion of alleleT carriers (CT and TT genotypes) was higher in healthy controls (9.7%) than in alcoholic patients (6.5%; P=.042). However, multivariable logistic regression analyses did not yield a significant result. No differences between groups were found for other analyzed polymorphisms. CONCLUSIONS: Our study describes, for the first time, the expected frequencies of certain polymorphisms within miRNA-binding sites in alcoholic patients with and without ALD. Further studies should be developed to clarify the potential relevance of these polymorphisms in alcoholism and ALD development. PMID- 29566964 TI - An atypical cause of pulmonary hypertension in the elderly. PMID- 29566965 TI - Predicting eventual development of lupus nephritis at the time of diagnosis of systemic lupus erythematosus. AB - OBJECTIVES: To investigate factors predictive of future lupus nephritis development when systemic lupus erythematosus (SLE) is diagnosed. METHODS: Patients with newly diagnosed SLE without renal manifestations were followed for development of lupus nephritis, comparing findings at baseline between those who did or did not develop nephritis. Albumin-to-globulin ratio (AGR) was calculated as albumin/(total protein-albumin). Cox proportional hazard model was used to identify predictors of lupus nephritis. RESULTS: Of 278 patients, 241 did not and 37 did develop lupus nephritis during follow-up. On univariate analysis, young age, low C3, low C4, high anti-dsDNA titre, anti-Sm antibody, anti-RNP antibody and low AGR were associated with a higher risk of lupus nephritis. On multivariate analysis, factors predictive of nephritis were age [adjusted hazard ratio (aHR) 0.928, 95% confidence interval (CI): 0.895-0.961, p < 0.001], C3 (aHR 0.977, 95% CI: 0.966-0.989, p < 0.001), anti-dsDNA titre (aHR 1.004, 95% CI: 1.000-1.007, p = 0.026) and anti-Sm antibody (aHR 2.097, 95% CI: 1.040-4.229, p = 0.038). In particular, a low AGR (aHR 4.972, 95% CI: 2.394-10.326, p < 0.001) was strongly associated with an increased risk of future lupus nephritis development. CONCLUSION: Young age, low C3, high anti-dsDNA titre and presence of anti-Sm antibody at diagnosis of SLE were associated with a risk of future lupus nephritis, but the hazard was greatest with a low AGR value, suggesting that a greater proportion of immunoglobulin relative to total protein is associated with the development of nephritis. PMID- 29566966 TI - Considerations for the definition of remission criteria in psoriatic arthritis. AB - OBJECTIVES: Psoriatic arthritis (PsA) is an autoimmune disease that can cause progressive structural damage of the joints and irreversible disability. The potentially achievable results of biologic therapy for PsA has led to the view that disease remission should be the goal of treatment. However, the heterogeneity of disease manifestations and need for validated outcome measures makes defining remission in PsA challenging. This article evaluates proposed criteria for defining remission in PsA and discusses how these criteria can be applied in clinical practice. METHODS: A primary literature search was conducted in PubMed to identify articles discussing potential PsA treatment goals or targets, including minimal disease activity. English-language publications from the last 10 years were included in this assessment. RESULTS: There are 5 clinical domains in PsA that must be considered when evaluating remission: synovitis, enthesitis, dactylitis, spondylitis, and psoriasis/nail psoriasis. Due to variability in the completeness of remission and time to achieve remission with different therapies between these domains, remission should be measured clinically through a combination of objective measures, or a composite assessment tool. Composite measures are more efficient than unidimensional instruments in measuring remission, but remission rates differ between the available composite indices. CONCLUSION: Although the concept of remission as a treatment goal in PsA is gaining acceptance among rheumatologists, further work is necessary to develop a broadly acceptable definition of remission. PMID- 29566967 TI - Serum urate as surrogate endpoint for flares in people with gout: A systematic review and meta-regression analysis. AB - OBJECTIVES: The primary efficacy outcome in trials of urate lowering therapy (ULT) for gout is serum urate (SU). The aim of this study was to examine the strength of the relationship between SU and patient-important outcomes to determine whether SU is an adequate surrogate endpoint for clinical trials. METHODS: Multiple databases through October 2017 were searched. Randomized controlled trials comparing any ULT in people with gout with any control or placebo, >=three months duration were included. Open label extension (OLE) trial data were included in secondary analyses. Standardized data elements were extracted independently by two reviewers. RESULTS: Ten RCTs and 3 OLE studies were identified. From the RCTs (maximum duration 24 months) meta-regression did not reveal an association between the relative risk of a gout flare and the difference in proportions of individuals with SU < 6mg/dL (P = 0.47; R2 = 8%). In a post hoc analysis, the ratio of the time in months at which the proportion of individuals having a flare was reported/time in months at which the proportion of individuals with SU < 6mg/dL was reported was calculated and studies where the ratio was <2 were excluded. Using the remaining 6 studies there was an association between proportion of individuals achieving SU < 6mg/dL and gout flares (over patient years). Duration of ULT was inversely associated with the proportion of patients experiencing a flare. Study duration and variability in reporting of outcomes limited the analysis. Observational studies supported the trend of fewer flares in those with lower SU. CONCLUSIONS: Based on aggregate clinical trial-level data an association between SU and gout flare could not be confirmed. However, based on observational ecological study design data-including longer duration extension studies-SU < 6mg/dL was associated with reduced gout flares. PMID- 29566968 TI - Whole-body computed tomography as a factor associated with lower mortality in severe geriatric trauma with thoracic-abdominal-pelvic injury. AB - OBJECTIVE: To determine the relationship between the use of whole-body computed tomography (WB-CT) and hospital mortality in elderly patients with thoracic abdominal-pelvic injury requiring admission to an intensive care unit. PATIENTS AND METHOD: An observational, descriptive and retrospective study was conducted on 140 patients aged 65 years and older admitted to the intensive care unit after a thoracic-abdominal-pelvic injury. Two groups were established, depending on whether a WB-CT was performed as a routine part of the study or the diagnosis was established by conventional radiography or ultrasound. A comparative analysis was performed on both groups, as well as an analysis of mortality through logistic regression. RESULTS: The mean age of the patients was 75.16+/-8.89 years. The mean score on the APACHE II scale was 16.25+/-8.4 points, and on the Injury Severity Score scale, 22.38+/-15.45 points. WB-CT was performed on 102 patients (72.9%). In these patients, there was a lower mortality rate (15.7 vs. 52.6%, P?.001), a lower need for mechanical ventilation (47.1 vs. 65.8%, P=.049), and a lower score on the APACHE II scale (14.75+/-7.19 vs. 20.26+/-10.06 points, P=.003). The multivariate analysis showed a lower mortality in the patients in whom WB-CT was performed, with an OR of 0.21 (95% CI 0.07-0.68; (P=.010), after adjusting for the APACHE II and ISS scores. CONCLUSIONS: Performing a WB-CT scan as part of the trauma study could improve the management of elderly patients with thoracic-abdominal-pelvic involvement admitted to the intensive care unit.

AB - OBJECTIVE: This study assessed vena cava filter (VCF) retrieval rates and factors associated with retrieval failure in a single center cohort. METHODS: We conducted an observational retrospective cohort study. The primary endpoint was the percentage of patients whose VCF was retrieved. We performed logistic regression to identify variables associated with retrieval failure. RESULTS: During the study period, 246 patients received a VCF and met the eligibility requirements to be included in the study; 151 (61%) patients received a VCF due to contraindication to anticoagulation, 69 (28%) patients had venous thromboembolism (VTE) and a high risk of recurrence, and 26 (11%) patients received a filter due to recurrent VTE while on anticoagulant therapy. Of 236 patients who survived the first month after diagnosis of VTE, VCF was retrieved in 96%. Retrieval rates were significantly lower for patients with recurrent VTE while on anticoagulation, compared with patients with contraindication to anticoagulation or patients with a high risk of recurrence (79% vs. 97% vs. 100%, respectively; P<0.01). Mean time to retrieval attempt was significantly associated with retrieval failure (137.8 +/- 65.3 vs. 46.3 +/- 123.1 days, P<0.001). CONCLUSIONS: In this single center study, VCF retrieval success was 96%. A delay in the attempt to retrieve the VCF correlated significantly with retrieval failure. PMID- 29566971 TI - The MEGA Project: A Study of the Mechanisms Involved in the Genesis and Disease Course of Asthma. Asthma Cohort Creation and Long-Term Follow-Up. AB - The general aim of this study is to create a cohort of asthma patients with varying grades of severity in order to gain greater insight into the mechanisms underlying the genesis and course of this disease. The specific objectives focus on various studies, including imaging, lung function, inflammation, and bronchial hyperresponsiveness, to determine the relevant events that characterize the asthma population, the long-term parameters that can determine changes in the severity of patients, and the treatments that influence disease progression. The study will also seek to identify the causes of exacerbations and how this affects the course of the disease. Patients will be contacted via the outpatient clinics of the 8 participating institutions under the auspices of the Spanish Respiratory Diseases Networking System (CIBER). In the inclusion visit, a standardized clinical history will be obtained, a clinical examination, including blood pressure, body mass index, complete respiratory function tests, and FENO will be performed, and the Asthma Control Test (ACT), Morisky-Green test, Asthma Quality of Life Questionnaire (Mini AQLQ), the Sino-Nasal Outcome Test 22 (SNOT-22), and the Hospital Anxiety and Depression scale (HADS) will be administered. A specific electronic database has been designed for data collection. Exhaled breath condensate, urine and blood samples will also be collected. Non-specific bronchial hyperresponsiveness testing with methacholine will be performed and an induced sputum sample will be collected at the beginning of the study and every 24 months. A skin prick test for airborne allergens and a chest CT will be performed at the beginning of the study and repeated every 5 years.

AB - Remyelination following myelin/oligodendrocyte injury in the central nervous system (CNS) is dependent on oligodendrocyte progenitor cells (OPCs) migrating into lesion sites, differentiating into myelinating oligodendrocytes (OLs), and ensheathing axons. Experimental models indicate that robust OPC-dependent remyelination can occur in the CNS; in contrast, histologic and imaging studies of lesions in the human disease multiple sclerosis (MS) indicate the variable extent of this response, which is particularly limited in more chronic MS lesions. Immune-mediated mechanisms can contribute either positively or negatively to the presence and functional responses of OPCs. This review addresses i) the molecular signature and functional properties of OPCs in the adult human brain; ii) the status (presence and function) of OPCs in MS lesions; iii) experimental models and in vitro data highlighting the contribution of adaptive and innate immune constituents to OPC injury and remyelination; and iv) effects of MS-directed immunotherapies on OPCs, either directly or indirectly via effects on specific immune constituents. PMID- 29566975 TI - Break the "wall" and become creative: Enacting embodied metaphors in virtual reality. AB - This study investigated whether the experience of "breaking the walls", the embodiment of the metaphor "breaking the rules", could enhance creative performance. The virtual reality technology was used to simulate the scenario where participants could "break the walls" while walking in a corridor. Participants were asked to solve the creativity-demanding problems (ie., alternative uses tasks, AUT) in either the "break" condition in which they had to break the walls to move forward in VR, or the "no-break" condition where no barrier walls would appear. Results showed higher AUT originality and AUT fluency in the "break" condition than in the "no-break" condition. Moreover, the effects of "breaking the walls" on AUT originality were fully mediated by cognitive flexibility and persistence. These findings may indicate that enacting metaphors such as "breaking the rules" contribute to creative performance. The enhanced cognitive flexibility and persistence may account for the benefits. PMID- 29566974 TI - Donor human milk and risk of surgical necrotizing enterocolitis: A meta-analysis. AB - BACKGROUND & AIM: The prevention of necrotizing enterocolitis (NEC) is a primary goal in the care of preterm and low birth-weight infants. Donor-banked milk (DM) feeding has been reported to have a protective effect towards NEC with respect to formula-feeding. All the meta-analysis published so far, have been focused on the protective effect of DM on the overall risk of NEC, none of them focused on the risk of the most severe cases on NEC only, that are those requiring surgery. We conducted a meta-analysis of available evidences on the risk of developing surgical cases of NEC in DM-fed preterm and/or low birth weight infants with respect to those formula-fed. METHODS: A search for articles published between January 1960 and January 2018 and addressing the association between DM and surgical NEC was conducted via PubMed, Embase and Cochrane database. We included randomized controlled clinical trials, reporting primary data and involving preterm and/or low birth weight infants fed with preterm formula compared to DM, both as sole diet or complementing own mother's milk. Estimates were pooled using random-effects. Study quality was assessed by GRADE score and risk of bias by the Review Manager software tool. RESULTS: Four papers were included in the meta analysis. DM did not exert a beneficial effect of DM on the risk of preventing surgical NEC with respect to formula (RR: 0.45; 95% CI: 0.19-1.09). CONCLUSIONS: This meta-analysis indicates that DM does not exert a clear protective effect, on the surgical cases of NEC with respect to preterm formula. Since DM feeding implies remarkable extra cost for the preparation, storage and delivery of the milk with respect to preterm formula, stronger evidences are required to recommend this type of feeding as a preventive strategy for surgical NEC. Mother's milk, when available, could represents the best choice. PROSPERO REGISTRATION NUMBER: CRD42015020296. PMID- 29566976 TI - Implementation science theories to inform efforts for de-implementation of urologic oncology care practices resulting in overuse and misuse. AB - The field of implementation science has been conventionally applied in the context of increasing the application of evidence-based practices into clinical care, given evidence of underusage of appropriate interventions in many settings. Increasingly, however, there is recognition of the potential for similar frameworks to inform efforts to reduce the application of ineffective or potentially harmful practices. In this article, we provide some examples of clinical scenarios in which the quality problem may be overuse and misuse, and review relevant theories and frameworks that may inform improvement activities. PMID- 29566977 TI - CO suppresses prostate cancer cell growth by directly targeting LKB1/AMPK/mTOR pathway in vitro and in vivo. AB - BACKGROUND: CO is a freely diffusible gas that acts as a physiological mediator of many biological and cellular processes, which has been shown to possess anticancer effect in many kinds of cancers. However, the effect of CO on prostate cancer has not been demonstrated. Therefore, we analyzed the antitumor activities and related mechanisms of CO on prostate cancer in vitro and in vivo. METHODS: Cell viability of LNCaP and PC-3 cells after CORM-2 treatment was measured by CCK 8 assay, whereas the ATP production were detected by ATP detection assay. The early apoptosis induced by CO was evaluated by flow cytometry, and the expression level of apoptosis-related molecules (Caspases 3, 8, 9 and cleaved-Caspases 3, 8, 9) was detected using Western blot. Matrigel in vitro invasion assay was used to evaluate the effect of CO on cell invasion. We then evaluated the impact of CO on the expression of several key regulators involved in the LKB1 signaling pathway. At last, xenograft tumor in nude mice was used to further investigate the antitumor effect of CO in vivo. RESULTS: Our results showed that CO could significantly inhibit proliferation and invasion, and induce apoptosis in human prostate cancer cell lines. The expression of LKB1 could be up-regulated after CO treatment, and CO also could increase p-AMPK levels and decrease p-mTOR. Furthermore, LKB1 knockdown could weaken the effect of CO on prostate cancer cells. In vivo, CO treatment significantly suppressed tumor growth and induced apoptosis in xenografts tumor in nude mice. CONCLUSIONS: CO possesses striking anticancer effect in human prostate cancer cells in vitro and in vivo, which is largely mediated by LKB1-AMPK-mTOR axis. PMID- 29566978 TI - The relationship of travel distance with cystectomy access and outcomes. AB - PURPOSE: Regionalization of care and travel distance may result in unintended consequences for complex surgery such as cystectomy. Our objective was to evaluate effect of differential distance on cystectomy receipt among patients with muscle-invasive bladder cancer (MIBC) and investigate the association between travel distance and cystectomy outcomes such as readmission. METHODS: Using a linked data resource combining the NC Central Cancer Registry with claims data from Medicare, Medicaid, and private insurance plans, we included 736 patients with MIBC and 1,082 who underwent cystectomy. To evaluate access, differential distance was calculated as the difference between the nearest urologist and nearest cystectomy provider. To assess outcomes, logistic regression was used to evaluate rehospitalization and major complications, and Cox proportional hazards model for survival analysis. RESULTS: To evaluate access and outcomes, 736 patients with MIBC and 1,082 patients undergoing cystectomy were evaluated, respectively. Overall, 29% (211 of 736) with MIBC underwent cystectomy. Differential distance was not a predictor of cystectomy receipt (odds ratio = 1.0; 95% CI: 1.00, 1.01). Among patients undergoing cystectomy, travel distance from cystectomy provider was not a significant predictor of 30- or 31 to 90day readmissions (odds ratio = 1.0; 95% CI: 1.00, 1.00) although patients who lived further from their cystectomy provider were more likely to be readmitted to a nonindex hospital (P<0.001) when controlling for other factors. Although travel distance did not have a significant effect on overall survival, patients readmitted between 31 to 90days had worse overall survival (P<0.0001). CONCLUSIONS: The additional distance needed to reach a cystectomy provider did not predict receipt of surgery for MIBC. Furthermore, travel distance from cystectomy provider was not a significant predictor for subsequent readmission after cystectomy and did not affect overall survival. PMID- 29566979 TI - Beyond genes: A systematic review of environmental risk factors in specific reading disorder. AB - BACKGROUND: While an understanding of the genetic contributions to specific reading disorder (RD) is emerging, there is no agreement about which putative hazard factors are clearly involved in the aetiology of this disorder. AIMS: A literature review looking at the impact of environmental risk variables implicated in RD either per se or when interacting with the genes. METHODS AND PROCEDURES: We performed a systematic literature review using the following keywords: dyslexia OR reading disability AND environmental risk factors OR environmental hazard factors, in the following electronic databases: PubMed, Scopus and PsycINFO, without any time restrictions. OUTCOMES AND RESULTS: Gestational weeks and birth weight are among the pre- and peri-natal risk factors shown to reliably predict reading readiness and the odds of having RD. Inconclusive findings have been reported for maternal cigarette smoking, family history of psychiatric and medical diseases, and risk of miscarriage. A broad definition of familial socio-economic status and home literacy environment have been identified as good life-long risk predictors of reading skills. CONCLUSIONS AND IMPLICATIONS: We highlighted the need to consider environmental hazards, their interactions and interactions with RD-candidate genes in the study of the aetiology of RD in order to provide much-needed insight into how these variables influence reading skills.

PMID- 29566981 TI - Anxiety-related psychopathology and chronic pain comorbidity among public safety personnel. AB - Canadian Public Safety Personnel (PSP; e.g., correctional service officers, dispatchers, firefighters, paramedics, police officers) regularly experience potentially traumatic, painful, and injurious events. Such exposures increase risk for developing mental disorders and chronic pain, which both involve substantial personal and social costs. The interrelationship between mental disorders and chronic pain is well-established, and both can be mutually maintaining; accordingly, understanding the relationship between mental health and chronic pain among PSP is important for improving health care. Unfortunately, the available research on such comorbidity for PSP is sparse. The current study was designed to provide initial estimates of comorbidities between mental disorders and chronic pain across diverse PSP. Participants included 5093 PSP (32% women) in six categories (i.e., Call Center Operators/Dispatchers, Correctional Workers, Firefighters, Municipal/Provincial Police, Paramedics, Royal Canadian Mounted Police) who participated in a large PSP mental health survey. The survey included established self-report measures for mental disorders and chronic pain. In the total sample, 23.1% of respondents self-reported clinically significant comorbid concerns with both mental disorders and chronic pain. The results indicated PSP who reported chronic pain were significantly more likely to screen positive for posttraumatic stress disorder (PTSD), major depressive disorder, generalized anxiety disorder, social anxiety disorder, and alcohol use disorder. There were differences between PSP categories; but, the most consistent indications of comorbidity were for chronic pain, PTSD, and major depressive disorder. Comorbidity between chronic pain and mental disorders among PSP is prevalent. Health care providers should regularly assess PSP for both symptom domains.

AB - BACKGROUND: Pelvic ring fractures might have consequences for health-related quality of life (HrQoL). The main purpose of this study was to evaluate patients' HrQoL after a pelvic ring fracture, considering the patients' characteristics. A cross-sectional study was conducted using the EuroQoL-5D (EQ-5D) and the Majeed pelvic score (MPS). METHODS: One hundred ninety-five patients (86%) with pelvic ring fractures who were conservatively or surgically treated in a level 1 trauma centre between 2011 and 2015 were included in this study (mean follow up: 29 months, range 6-61). A telephone survey of all patients was conducted. Multiple logistic and linear regression analyses were used for statistical assessment with the EQ-5D and the MPS. The MPS results were split into two age groups with a cut off point of 65 years. RESULTS: EQ-5D: The mean EQ-5D Visual Analogue Scale (VAS) for Tiles A-C was, respectively, 74 (SD 18), 74 (SD 19) and 67 (SD 21), and the mean EQ-5D index score was, respectively, 0.81 (SD 0.23), 0.77 (SD 0.30) and 0.71 (SD 0.26). Compared with Tile A, patients in Tile C experienced significantly more pain (odds ratio 6.28 (1.73-22.82 95% CI), P < 0.01). Clinically relevant differences in EQ-5D scores between Tile A and Tile C were seen in the domains of usual activities and anxiety and in the index score. MPS: The mean MPS of Tiles A C patients in the <65 group was, respectively, 86 (SD 15), 81 (SD 17), and 74 (SD 16), and in the >=65 group, it was, respectively, 69 (SD 15), 68 (SD 15) and 66 (SD 9). In the <65 group, significant differences in MPS results between the Tile groups regarding pain (P < 0.01) and the total MPS score (P = 0.04) were seen. Neither significant regression coefficients nor clinically relevant differences were found in the >=65 group. CONCLUSIONS: In conclusion, our study showed that pain was increased in patients with Tile C fractures, compared with Tiles A and B. Furthermore, Tile C patients had significantly lower EQ-5D index and total MPS scores. However, these problems were not seen in the >=65 group. PMID- 29566986 TI - Fractures of the femur and blood transfusions. AB - BACKGROUND: Blood loss estimation after trauma (i.e. physical injury) and early identification of potential sources of bleeding are important for planning of investigation and management of trauma. Long bone fractures have been reported to be associated with substantial volumes of blood loss requiring blood transfusion. The aim of this study was to assess rates and amounts of blood transfusion in the setting of isolated extra capsular femur fractures and to determine variables associated with the need for transfusion within the first 48 h of admission. METHODS: A retrospective cohort study was conducted of patients in The Alfred Trauma Registry with isolated extra capsular femur fractures over a 7-year period. We compared patients with a femoral shaft fracture (FSF) to patients with either distal femur or proximal femur fractures (i.e. extremity fracture). We collected data potentially associated with blood transfusion within 48 h as well as operation details and patient outcomes. RESULTS: There were 293 patients included, of which 121 had FSF and 172 extremity fracture. 105 (36%) patients received a blood transfusion during their admission. Admission haemoglobin (AOR 0.92; 95%CI 0.89-0.94, p < 0.01) was the only independently associated variable with blood transfusion within the first 48 h of hospital admission. CONCLUSION: Volume of blood transfused to patients with extra-capsular femoral fractures was low and usually in the post-operative period. FSF, compared to femoral extremity fractures, were not more likely to receive blood transfusion within the first 48 h of admission, and did not receive a higher volume of blood overall. In the setting of major trauma with haemorrhagic shock, alternate sources of bleeding should be sought. PMID- 29566987 TI - Efficacy and safety of novel collagen conduits filled with collagen filaments to treat patients with peripheral nerve injury: A multicenter, controlled, open label clinical trial. AB - INTRODUCTION: The safety and efficacy of using artificial collagen nerve conduits filled with collagen filaments to treat nerve defects has not been fully studied in humans. We conducted a multicenter, controlled, open-label study to compare the safety and efficacy of artificial nerve conduit grafts with those of autologous nerve grafts. METHODS: We included patients with a sensory nerve defect of <=30 mm, at the level of the wrist or a more distal location, with the first-line surgical methods selected according to a patient's preference. We compared sensory recovery using static two-point discrimination and adverse events between the artificial collagen nerve conduit and autologous nerve grafting. RESULTS: The artificial nerve conduit group included 49 patients, with a mean age of 42 years and nerve defect of 12.6 mm. The autologous nerve graft group included 7 patients, with historical data of an additional 31 patients, with a mean age of 36 years and nerve defect of 18.7 mm. The rate of recovery of sensory function at 12 months was 75% (36/49) for the artificial nerve conduit group and 73.7% (28/38) in the autologous nerve group. No serious adverse events directly associated with use of the artificial nerve conduit were identified. CONCLUSIONS: The treatment of nerve defects <=30 mm using artificial collagen nerve conduits was not inferior to treatment using autologous nerve grafts. Based on our data, the new artificial collagen nerve conduit can provide an alternative to autologous nerve for the treatment of peripheral nerve defects. PMID- 29566988 TI - How can MRI change the treatment strategy in apparently isolated greater trochanteric fracture? AB - INTRODUCTION: The purpose of this study was to evaluate the proportion of greater trochanter (GT) fractures with occult extension to the intertrochanteric region on magnetic resonance imaging (MRI) among apparently isolated GT fractures and to investigate the use of MRI for formulating a treatment strategy in patients with isolated GT fractures. PATIENTS AND METHODS: This retrospective cohort study reviewed 37 patients with isolated GT fractures on plain radiography. Surgical or conservative treatment was decided according to MRI findings. We divided patients into 3 groups according to the extension of the fracture line. In group 1, the fracture line was within the lateral one-third in the coronal plane. In group 2, the fracture line extended from the lateral one-third to the medial one-third. In group 3, the fracture line extended over the medial one-third and/or to the medial cortex of the femur. Conservative treatment was performed in groups 1 and 2, and surgical treatment was performed in group 3. The clinical results, radiography findings, and MRI findings were investigated. RESULTS: MRI revealed hidden intertrochanteric fractures (groups 2 [n = 10] and 3 [n = 4]) in 38% of apparently isolated GT fractures on radiography. No displacement was found in groups 1 (n = 23) and 2. Of the 4 patients in group 3, 3 were treated surgically and achieved good functional results and 1 refused to undergo surgery and finally developed complete intertrochanteric fracture. This patient presented 5 days later with increased hip pain, and radiography demonstrated displacement of the fracture, prompting surgical intervention. CONCLUSIONS: The evaluation of apparently isolated GT fractures using MRI can be useful to diagnose the extent of the occult fracture and determine the treatment strategy.

PMID- 29566990 TI - Preserving and perfusing the allograft pancreas: Past, present, and future. AB - The concept of organ preservation by perfusion dates back to the mid-19th century. Innovations since then have included temperature regulation, perfusion fluid composition and various pumping systems. Advances made in liver, heart and kidney machine preservation are now contributing to increased graft utilisation, assessment of graft viability and potentially improved graft survival. Pancreas transplantation has not benefitted to the same extent from the application of perfusion technology, although the need is just as great. This overview reviews current pancreas specific preservation techniques. We explore concepts, which include static cold storage, use of preservation solutions, the 'two-layer method', and machine perfusion. We also discuss ideas for future development. Narrative review of literature from inception to December 2017 using OVID interfaces searching EMBASE, Google Scholar, and MEDLINE databases. All studies relevant to pancreas perfusion and preservation were examined for clinical relevance with no exclusion criteria. Conference papers and presentations were also reviewed and included where appropriate. The application of recent advances in understanding in ischaemia-reperfusion as well as technical developments in machine preservation Ischaemia-reperfusion have the potential to improve organ utilisation, viability and outcome.

Recent research discovered that the expression of miR-422a was significantly decreased in colorectal cancer tissues, providing miR-422a as a tumor suppressor in CRC. However, the concrete mechanism of miR-422a regulating CRC cell is still unclear. In this study, we demonstrated that miR-422a could inhibit CRC cell growth and promote cell apoptosis via in vitro analyses. Moreover, computational methods were adopted to identify the targets of miR-422a. We found MAPKK6 was the direct target of miR-422a. Consequently, we further elucidated that miR-422a inhibited CRC cell growth and induced cell apoptosis by inhibiting p38/MAPK pathway. Besides that, we established the tumor xenograft model using nude mice and the inhibitory effects on tumor volumes and weights by miR-422a mimic transfection were also detected. Taken together, these findings demonstrated miR 422a exerted anti-cancer activities on CRC, which could be potentially used for CRC prognosis prediction and treatment. PMID- 29566994 TI - Volumetric Textural Analysis of Colorectal Masses at CT Colonography: Differentiating Benign versus Malignant Pathology and Comparison with Human Reader Performance. AB - RATIONALE AND OBJECTIVES: To (1) apply a quantitative volumetric textural analysis (VTA) to colorectal masses at CT colonography (CTC) for the differentiation of malignant and benign lesions and to (2) compare VTA with human performance. MATERIALS AND METHODS: A validated, quantitative VTA method was applied to 63 pathologically proven colorectal masses (mean size, 4.2 cm; range, 3-8 cm) at noncontrast CTC in 59 adults (mean age, 66.5 years; range, 45.9-91.6 years). Fifty-one percent (32/63) of the masses were invasive adenocarcinoma, and the remaining 49% (31/63) were large benign adenomas. Three readers with CTC experience independently assessed the likelihood of malignancy using a 5-point scale (1 = definitely benign, 2 = probably benign, 3 = indeterminate, 4 = probably malignant, 5 = definitely malignant). Areas under the curve (AUCs) and accuracy levels were compared. RESULTS: VTA achieved optimal sensitivity of 83.6% vs 91.7% for human readers (P = .034), with specificities of 87.5% and 77.4%, respectively (P = .007). No significant difference in overall accuracy was seen between VTA and human readers (85.5% vs 84.7%, P = .753). The AUC for differentiating benign and malignant lesions was 0.936 for VTA and 0.917 for human readers. Intraclass correlation coefficient among the human readers was 0.76, indicating good to excellent agreement. CONCLUSION: VTA demonstrates excellent performance for distinguishing benign from malignant colorectal masses (>=3 cm) at CTC, comparable yet potentially complementary to experienced human performance.

AB - Cerebral Cavernomas (CC) are vascular malformations located in the Central Nervous System (CNS) characterized by endothelium-lined vascular channels without parenchyma between them, whose main risk is hemorrhage. The aim of this study is to report adult cancer patients that developed CC after radiotherapy (RT) to the CNS during oncological surveillance. PMID- 29566996 TI - The impact of chemotherapeutic treatment on the oral microbiota of patients with cancer: a systematic review. AB - OBJECTIVE: Chemotherapy is a type of systemic treatment that inhibits neoplastic cells (cancer cells), produces immunosuppression, and may lead to changes in the oral mucosa and, consequently, in the oral microbiota. The aim of this systematic review was to analyze, in the scientific literature, evidence of the impact of chemotherapy on the oral microbiota. STUDY DESIGN: The authors conducted a search in PubMed/MEDLINE, Scientific Electronic Library Online (SciELO), LILACS, ScienceDirect, Web of Science, and Cochrane Library; to identify studies that discussed change in the oral microbiota of patients with during chemotherapy. Articles published in English until July 2017 were included. The quality of a study was assessed by using the Ottawa-Newcastle scale. RESULTS: Of 5252 articles potentially relevant to this review, 17 were included in this study. Of the 17 studies included, 16 had used culture techniques, and 1 had used genetic sequencing. The most frequently observed bacteria were aerobic gram-negative (Klebsiella spp., Escherichia coli, Enterobacter, Pseudomonas spp.), anaerobic gram-negative (Veillonella spp., Capnocytophaga), and gram-positive bacteria (Streptococcus spp., Staphylococcus spp.). CONCLUSIONS: During chemotherapy, patients with cancer present a more complex oral microbiota under favorable conditions for their development during immunosuppression, and these may be responsible for different serious local or systemic pathologies. PMID- 29566997 TI - [Quality of care and safety indicators in anticoagulated patients with non valvular auricular fibrillation and deep venous thromboembolic disease]. AB - OBJECTIVES: To identify and prioritise indicators to assess the quality of care and safety of patients with non-valvular auricular fibrillation (NVAF) and deep vein thrombosis (DVT) treated with anticoagulants. MATERIALS AND METHODS: Using the consensus conference technique, a group of professionals and clinical experts, the determining factors of the NVAF and DVT care process were identified, in order to define the quality and safety criteria. A proposal was made for indicators of quality and safety that were prioritised, taking into account a series of pre-established attributes. The selected indicators were classified into indicators of context, safety, action, and outcomes of the intervention in the patient. RESULTS: A set of 114 health care and safety quality indicators were identified, of which 35 were prioritised: 15 for NVAF and 20 for DVT. About half (49%) of the indicators (40% for NVAF and 55% for DVT) applied to patient safety, and 26% (33% for NVAF and 20% for DVT) to the outcomes of interventions in the patient. CONCLUSIONS: The present work presents a set of agreed indicators by a group of expert professionals that can contribute to the improvement of the quality of care of patients with NVAF and DVT treated with anticoagulants.

PMID- 29567000 TI - No Difference in Outcomes 12 and 24 Months After Lower Extremity Total Joint Arthroplasty: A Systematic Review and Meta-Analysis. AB - BACKGROUND: A better understanding of how patient-reported outcome measures (PROMs) change after total knee and hip arthroplasties (TKA and THA) is needed to support the minimum arbitrary follow-up of 24-months required by orthopedic journals. Therefore, our purpose was to perform a systematic review and meta analysis of the THA and TKA literature to determine if equivalence exists between 12- and 24-month outcomes data. METHODS: A search was performed using the PubMed and EMBASE databases for primary and revision THA and TKA studies reporting PROMs data at both 12 and 24 months. Reports on PROMs for TKA and THAs were included for meta-analysis to detect statistical differences at 12 and 24 months. RESULTS: A total of 15 reports from 9 TKA (n = 1564) and 6 THA (n = 740) reports were analyzed. The mean change between 12 and 24 months for Knee Society Score was 0.15 absolute points (95% confidence interval [CI]: 0.97-1.06, P = .13) and for Western Ontario and McMaster Universities Osteoarthritis index was 0.50 absolute points (95% CI: 0.94-1.07, P = .49). The mean change between 12 and 24 months for Harris Hip Score was 2.01 absolute points (95% CI: 0.94-1.1, P = .22) and for short form was 0.02 absolute points (95% CI: 0.92-1.08, P = .94). CONCLUSION: No different outcomes were found within THA and TKA for 4 PROMs at 12- and 24-month follow-up. Although the findings from this study do not alleviate the need for collecting data from longer follow-up periods, there may not be additional value in collecting short-term outcomes data in routine practice at both 1 and 2 years. PMID- 29567001 TI - The James A. Rand Young Investigator's Award: Battling the Opioid Epidemic with Prospective Pain Threshold Measurement. AB - BACKGROUND: Responsible analgesic prescribing is paramount in the opioid epidemic era, yet no standardized protocol exists. We aim to (1) quantify and correlate outpatient opioid need after total knee and hip arthroplasties (TKA and THA) with preoperative objective pain pressure thresholds (PPTs) and subjective pain measures and (2) report incidence of nonsurgical opioid prescriptions 6 weeks postoperatively. METHODS: Prospectively, PPTs were measured using an algometer with a maximum force of 20 pounds in 160 consecutive patients (90 TKA and 70 THA). Two locations were tested: operative joint (medial epicondyle TKA and lateral iliac crest THA) and ipsilateral olecranon for systemic control. Visual Analog Score, Pain Severity Score, Pain Interference Score, and subjective pain threshold were obtained. Six-week outpatient narcotic consumption morphine equivalents recorded and prescriptions crosschecked with the state Controlled Substance Reporting System. Multivariate analysis was performed to evaluate local and/or systemic PPT and subjective measures with narcotic consumption. RESULTS: Average operative site and systemic PPT was 6.91 and 7.72 pounds force, respectively. Subjective averages: Visual Analog Score 7.14, Pain Severity Score 5.05, Pain Interference Score 5.16, and perceived threshold 6.77. Six-week average outpatient narcotic consumption was 314.9 morphine equivalents or 125 five milligram oxycodones. Twenty percent received opioids from outside providers. Linear regression revealed a negative correlation between operative site PPT (-0.26; P = .047) and systemic PPT (-0.31; P = .021). Subjective pain metrics failed to meet significance. CONCLUSION: This novel study demonstrated a statistically significant negative correlation between preoperative pain threshold and outpatient narcotic consumption. Twenty percent of patients received opioid prescriptions outside orthopedic providers in the 6 weeks after surgery highlighting the importance of interdisciplinary communication. PMID- 29567002 TI - How Much Pain Is Significant? Defining the Minimal Clinically Important Difference for the Visual Analog Scale for Pain After Total Joint Arthroplasty. AB - BACKGROUND: The ability to detect changes in patient-perceived pain after total joint arthroplasty (TJA) is critical to manage postoperative pain. The minimal clinically important difference (MCID) for visual analog scale for pain (VAS-P) has not been investigated in this population. This study investigated the MCID for VAS-P in the TJA population. METHODS: Postoperative pain scores were collected on 139 total hip arthroplasty (THA) and 165 total knee arthroplasty (TKA) patients. VAS-P was measured and Likert scores for changes in pain recorded together throughout the hospitalization per patient. Using a linear mixed model, the mean difference between preceding and current VAS-P was calculated and correlated with Likert score, when the patient reported at least slight improvement or worsening in pain, defining the MCID. Minimal detectable change was calculated using the VAS-P standard error of the means for patients reporting "no change." RESULTS: For THA, the overall mean and average highest VAS-P were 35.0 mm and 50.4 mm, respectively. For TKA, the overall mean and average highest VAS-P were 42.6 mm and 61.1 mm, respectively. The minimal detectable change in VAS-P was 14.9 mm for THA and 16.1 mm for TKA. The MCID for THA and TKA pain improvement was -18.6 mm and -22.6 mm, respectively, and for worsening was 23.6 mm and 29.1 mm, respectively. CONCLUSION: In the postoperative TJA population, VAS-P MCID changes depend on the type of surgical intervention, and whether pain is improving or worsening. Statistically significant VAS-P, improving -18.6 mm and -22.6 mm for THA and TKA patients, respectively, sets a reasonable threshold to identify clinically meaningful pain intervention with high specificity. PMID- 29567003 TI - A Computer Model of Mid-Flexion Instability in a Balanced Total Knee Arthroplasty. AB - BACKGROUND: Some patients have mid-flexion instability despite stability at 0 degrees and 90 degrees of flexion. This study aims to determine the effects of total knee arthroplasty (TKA) stability while changing femur implant size and position. METHODS: A computational analysis was performed simulating knee flexion of posterior stabilized (PS) and cruciate retaining (CR) TKA designs. Deviations from the ideal TKA implant position were simulated by adjusting tibiofemoral proximal-distal position and femur anterior-posterior position as well as implant size. Forces in ligaments connecting the femur and tibia were collected. Total tibiofemoral ligament load for mid-knee flexion of 15 degrees -75 degrees was analyzed vs proximal-distal implant position, implant size, implant design, and knee flexion for PS and CR knees. Posterior cruciate ligament load was also analyzed for CR knees. RESULTS: Total tibiofemoral ligament load was significantly reduced by a more proximal tibiofemoral and anterior femur position (P < .001). Implant size did not have a significant effect on tibiofemoral ligament load (P > .1). Implant design and knee flexion significantly influenced total tibiofemoral ligament load (P < .001), but the interactions with implant proximal-distal position were not significant (P > .2), indicating that implant proximal-distal position had a similar effect across the 15 degrees -75 degrees knee flexion range for both studied PS and CR implant designs. CONCLUSION: PS and CR TKA can be well-balanced at 0 degrees and 90 degrees knee flexion and have instability in mid-flexion. Elevating the joint line and shifting the femur anteriorly can cause the knee to be too loose in mid-flexion. PMID- 29567004 TI - Suicide in parachuting: A case report and review of the literature. AB - Skydiving fatalities are mostly accidental and the result of human errors. However, suicides may be greatly underreported in skydivers. We present the case of a young civilian skydiver who committed suicide by jumping from an altitude of 4000m without activating his chutes. Witnesses reported that the victim had remained in a freefall position until ground impact. Besides an extensive blunt trauma, the autopsy showed an antero-posterior flattening of the body with symmetrical abrasions on its front, which were consistent with a high-energy impact on the ground in a "belly-down" position. Police investigation revealed that the victim had expressed suicidal thoughts in text messages before jumping from the airplane, and examination of his equipment showed that he had disabled the security system allowing the reserve chute to be automatically deployed at low altitude. To the best of our knowledge, this is the first case of suicide of a skydiver that has been described in the scientific literature. A suicidal intent should be assumed in skydiving fatalities involving jumpers with operable but un-activated parachutes on their back. This case highlights the importance of a thorough forensic investigation in such circumstances to ascertain the manner of death.

PMID- 29567007 TI - Reported Influences on Restaurant-Type Food Selection Decision Making in a Grocery Store Chain. AB - OBJECTIVE: To examine food decision-making priorities for restaurant-type foods at grocery stores and determine whether adding calorie information, as required by federal menu labeling laws, affected decision-making priorities. DESIGN: Natural experiment: intervention and control groups with baseline and follow-up. SETTING: Regional grocery store chain with 9 locations. PARTICIPANTS: Participants (n = 393; mean age, 54.8 +/- 15.1 years) were primarily women (71%) and Caucasian (95%). INTERVENTION: Data were collected before and after calorie information was added to restaurant-type foods at 4 intervention locations. MAIN OUTCOME MEASURE(S): Primary influencers of food selection decision making for restaurant-type foods and frequency of use of nutrition information. ANALYSIS: Quantitative analysis examined the top 3 influencers of food selections and chi square goodness of fit test determined whether the calorie labeling intervention changed food decision-making priorities. Qualitative data were used to describe responses. RESULTS: Taste, cost, and convenience were the most frequently reported influencers of restaurant-type food selections; 20% of participants rated calories as influential. Calorie labeling did not affect food selection decision making; 16% of participants in intervention stores noticed calorie labels. Qualitative explanations confirmed these findings. CONCLUSIONS AND IMPLICATIONS: Menu labeling laws increase access to calorie information; however, use of this information is limited. Additional interventions are needed to encourage healthier restaurant-type food selections in grocery stores. PMID- 29567006 TI - Chromoendoscopy versus autofluorescence imaging for neoplasia detection in patients with longstanding ulcerative colitis (FIND-UC): an international, multicentre, randomised controlled trial. AB - BACKGROUND: Patients with longstanding ulcerative colitis undergo regular dysplasia surveillance because they have an increased colorectal cancer risk. Autofluorescence imaging and chromoendoscopy improve dysplasia detection. The aim of this study was to determine whether autofluorescence imaging should be further studied as an alternative method for dysplasia surveillance in patients with longstanding ulcerative colitis. METHODS: This prospective, international, randomised controlled trial included patients from an ulcerative colitis dysplasia surveillance cohort from five centres in the Netherlands and the UK. Eligible patients were aged 18 years or older who were undergoing dysplasia surveillance after being diagnosed with extensive colitis (Montreal E3) at least 8 years before study start or with left-sided colitis (Montreal E2) at least 15 years before study start. Randomisation (1:1) was minimised for a previous personal history of histologically proven dysplasia and concomitant primary sclerosing cholangitis. The coprimary outcomes were the proportion of patients in whom at least one dysplastic lesion was detected and the mean number of dysplastic lesions per patient. The relative dysplasia detection rate, calculated as the ratio of the detection rates by autofluorescence imaging and chromoendoscopy, needed to be more than 0.67 (using an 80% CI) for both primary outcomes to support a subsequent large non-inferiority trial. Outcomes were analysed on a per-protocol basis. The trial is registered at the Netherlands Trial Register, number NTR4062. FINDINGS: Between Aug 1, 2013, and March 10, 2017, 210 patients undergoing colonoscopy surveillance for longstanding ulcerative colitis were randomised for inspection with either autofluorescence imaging (n=105) or chromoendoscopy (n=105). Dysplasia was detected in 13 (12%) patients by autofluorescence imaging and in 20 patients (19%) by chromoendoscopy. The relative dysplasia detection rate of autofluorescence imaging versus chromoendoscopy for the proportion of patients with ulcerative colitis with at least one dysplastic lesion was 0.65 (80% CI 0.43-0.99). The mean number of detected dysplastic lesions per patient was 0.13 (SD 0.37) for autofluorescence imaging and 0.37 (1.02) for chromoendoscopy (relative dysplasia detection rate 0.36, 80% CI 0.21-0.61). Adverse events were reported for two patients in the autofluorescence imaging group (one patient had intraprocedural mild bleeding, and one patient had abdominal pain) and for three patients in the chromoendoscopy group (two patients had intraprocedural mild bleeding, and one patient had perforation). INTERPRETATION: Autofluorescence imaging did not meet criteria for proceeding to a large non-inferiority trial. Therefore, existing autofluorescence imaging technology should not be further investigated as an alternative dysplasia surveillance method. FUNDING: Olympus Europe and Olympus Keymed. PMID- 29567008 TI - An Obesity Risk Assessment Tool for Young Children: Validity With BMI and Nutrient Values. AB - OBJECTIVE: Demonstrate validity and reliability for an obesity risk assessment tool for young children targeting families' modifiable home environments. DESIGN: Longitudinal design with data collected over 100 weeks. SETTING: Head Start and the Special Supplemental Nutrition Program for Women, Infants, and Children. PARTICIPANTS: Parent-child pairs (n = 133) provided food behavior assessments; 3 child-modified, 24-hour dietary recalls; 3 >= 36-hour activity logs; and measured heights and weights. MAIN OUTCOME MEASURE: Five measures of validity and 5 of reliability. RESULTS: Validity was excellent for the assessment tool, named Healthy Kids, demonstrating an inverse relationship with child body mass index percentile-for-age (P = .02). Scales were significantly related to hypothesized variables (P <= .05): fruit or vegetable cup equivalents; folate; vitamins A, C, and D; beta-carotene; calcium; fiber; sugar; screen, sleep, and physical activity minutes; and parent behaviors. Measures of reliability were acceptable. CONCLUSIONS AND IMPLICATIONS: Overall, children with higher Healthy Kids scores had a more healthful profile as well as lower body mass index percentiles-for-age 1.5 years later. Healthy Kids has potential for use by nutrition professionals as a screening tool to identify young children most at risk for excess weight gain, as an evaluation to assess intervention impact, and as a counseling tool to tailor intervention efforts. Future research should include validation in other settings and with other populations. PMID- 29567009 TI - Trend in unequal geographical distribution of doctors by age and sex in Japan from 2004 to 2014. AB - OBJECTIVES: In Japan, the proportion of female doctors and elderly doctors is increasing as in other countries. We investigated the relationship between doctors' demographic changes and their geographical distribution. STUDY DESIGN: A national database study. METHODS: We assessed trends in unequal geographical distribution of the number of doctors by sex and age from 2004 to 2014 in Japan. RESULTS: The Gini coefficient values for the number of female doctors (0.18) were larger than those for male doctors across all generations (0.13-0.14). The Gini coefficient values for the number of elderly doctors aged 60 years and older (male: 0.12, female: 0.18-0.23) were larger than those for majority age groups aged 40-59 years (male: 0.10, female: 0.16-0.17). CONCLUSION: The persisting geographical maldistribution of doctors may be associated with demographic changes, such as increase in the number of female doctors. PMID- 29567010 TI - Effect of increasing temperature on daily hospital admissions for schizophrenia in Hefei, China: a time-series analysis. AB - OBJECTIVE: To investigate the relationship between ambient temperature and hospital admissions for schizophrenia in Hefei, China. STUDY DESIGN: An ecological design was used to explore the effect of ambient temperature on hospital admissions for schizophrenia. METHODS: Daily data on hospital admissions for schizophrenia and meteorological data for the warm season (May-October) in 2005-2014 were obtained from Anhui Mental Health Centre and Hefei Bureau of Meteorology, respectively. Poisson generalised linear regression model combined with a distributed lag non-linear model was used to analyse the effects of temperature on admissions for schizophrenia. Stratified analyses according to individual characteristics, such as age and sex, were also conducted. RESULTS: A significant relationship was found between ambient temperature and admissions for schizophrenia. High temperature appeared to have a delayed effect on admissions for schizophrenia, and a temperature of 28 degrees C (75th percentile) at lag 0-4 days was associated with a 7% (95% confidence interval: 4-11%) increase in admissions for schizophrenia. Stratified analyses showed that male patients, patients aged 21-60 years and married patients were more vulnerable to high temperature, and the temperature effects for those groups occurred at a lag of 1 day. CONCLUSION: High temperature poses significant risks for schizophrenia in subtropical regions. Future preventive measures for reducing the occurrence of schizophrenia should be considered for susceptible populations. PMID- 29567011 TI - Impact of ambient fine particulate matter air pollution on health behaviors: a longitudinal study of university students in Beijing, China. AB - OBJECTIVES: Poor air quality has become a national public health concern in China. This study examines the impact of ambient fine particulate matter (PM2.5) air pollution on health behaviors among college students in Beijing, China. STUDY DESIGN: Prospective cohort study. METHODS: Health surveys were repeatedly administered among 12,000 newly admitted students at Tsinghua University during 2012-2015 over their freshman year. Linear individual fixed-effect regressions were performed to estimate the impacts of ambient PM2.5 concentration on health behaviors among survey participants, adjusting for various time-variant individual characteristics and environmental measures. RESULTS: Ambient PM2.5 concentration was found to be negatively associated with time spent on walking, vigorous physical activity and sedentary behavior in the last week, but positively associated with time spent on nighttime/daytime sleep among survey participants. An increase in the ambient PM2.5 concentration by one standard deviation (36.5 MUg/m3) was associated with a reduction in weekly total minutes of walking by 7.3 (95% confidence interval [CI] = 5.3-9.4), a reduction in weekly total minutes of vigorous physical activity by 10.1 (95% CI = 8.5-11.7), a reduction in daily average hours of sedentary behavior by 0.06 (95% CI = 0.02 0.10) but an increase in daily average hours of nighttime/daytime sleep by 1.07 (95% CI = 1.04-1.11). CONCLUSIONS: Ambient PM2.5 air pollution was inversely associated with physical activity level but positively associated with sleep duration among college students. Future studies are warranted to replicate study findings in other Chinese cities and universities, and policy interventions are urgently called to reduce air pollution level in China's urban areas. PMID- 29567012 TI - Staged laparoscopic traction orchiopexy for intra-abdominal testis: Is it always feasible? AB - BACKGROUND AND OBJECTIVES: Laparoscopic orchiopexy for intra-abdominal testis is a well-known and commonly practiced technique. The traction technique is based on elongation of the testicular vessels without cutting them, in contrast with the two-stage Fowler-Stephens technique in which the testicular vessels are divided. The current study evaluated the feasibility of the traction technique according to the type of intra-abdominal testis. PATIENTS AND METHODS: The study included 20 boys with 22 intra-abdominal testes and who underwent staged laparoscopic traction orchiopexy between October 2013 and October 2015. Eighteen testes were proximal to the internal ring by <2 cm (type III), while the remaining four were high and away from the internal ring by >2 cm (type IVa). The patients' ages ranged between 6 months and 5 years (mean 2.2 years; median 2 years). Patients were followed up for 1 year for testicular atrophy and satisfactory scrotal site relocation. RESULTS: This study did not detect any cases of testicular atrophy among the participants (0/22), while failure to achieve satisfactory scrotal site was found in two out of the four cases with type IVa intra-abdominal testes. DISCUSSION: Traction techniques for elongating the testicular vessels were employed years ago, but this was revisited by Shehata in 2008. It has the advantage of preserving the main testicular blood supply, which can be reflected by the decreasing rate of testicular atrophy when compared with the Fowler Stephens orchiopexy. The results of the traction technique may be less satisfactory regarding the testicular location for higher types of intra abdominal testes (type IVa). CONCLUSION: Staged laparoscopic traction orchiopexy was a feasible technique for intra-abdominal testes (within 2 cm of the internal ring), but the results were less satisfactory when applied for higher intra abdominal testes (type IVa).

Part 1: An overview of educational theory. AB - Surgical training has changed radically in the last few decades. The traditional Halstedian model of time-bound apprenticeship has been replaced with competency based training. Advanced understanding of mastery learning principles has vastly altered educational methodology in surgical training, in terms of instructional design, delivery of educational content, assessment of learning, and programmatic evaluation. As part of this educational revolution, fundamentals of simulation based education have been adopted into all levels and aspects of surgical training, requiring an understanding of concepts of fidelity and realism and the impact they have on learning. There are many educational principles and theories that can help clinical teachers understand the way that their trainees learn. In the acquisition of surgical expertise, concepts of mastery learning, deliberate practice, and experiential learning are particularly important. Furthermore, surgical teachers need to understand the principles of effective feedback, which is essential to all forms of skills learning. This article, the first of two papers, presents an overview of relevant learning theory for the busy paediatric surgeon and urologist. Seeking to introduce the concepts underpinning current changes in surgical education and training, providing practical tips to optimise teaching endeavours.

It should be considered as one of the differential diagnoses of spindle cell tumors of the kidney. Immunohistochemistry and genetic translocation studies should be used to confirm the diagnosis. Because of a lack of consistent literature data regarding the treatment options, management of PRSS remains a therapeutic challenge. In view of the chemosensitive nature of the tumor, we propose a multimodality treatment in form of surgery and chemotherapy in patients with PRSS. Here we report a rare case of PRSS in a 17-year-old adolescent. PMID- 29567017 TI - Reply by the Authors. PMID- 29567018 TI - Mechanism of Action of the Transobturator Sling for Post-Radical Prostatectomy Incontinence: A Multi-institutional Prospective Study Using Dynamic Magnetic Resonance Imaging. AB - OBJECTIVE: To compare the length of the membranous (functional) urethra in male patients who underwent the male transobturator sling (TOS) for postradical prostatectomy urinary incontinence (PPI). The TOS is in established use for treatment of PPI; however, the precise mechanism of action is unknown. MATERIALS AND METHODS: This is a prospective case-controlled study on men undergoing male TOS surgery from 2008 to 2014. The comparison arm included patients without incontinence after radical prostatectomy. All participants underwent dynamic magnetic resonance imaging (MRI) at baseline and this was repeated after TOS placement for those who underwent the procedure. Three standardized points were measured using MRI and compared in both groups in addition to clinical measures. RESULTS: Thirty-nine patients were enrolled and 31 patients completed the protocols. The controls (N = 14) had a longer vesicourethral anastomosis to urethra measured at the penile bulb (functional urethral length) distance compared to the pre-TOS group at rest (1.92 cm controls vs 1.27 cm pre-TOS, P = .0018) and at Valsalva (2.13 cm controls vs 1.72 cm pre-TOS, P = .0371). Placement of the sling (N = 17) increased the functional urethral length distance at rest (1.92 cm control vs 1.53 cm post-TOS, P = .09) and at Valsalva (1.94 cm post-TOS vs 2.13 cm control, P = .61), so that the difference was no longer statistically significant. CONCLUSION: We identified that one possible mechanism in improvement in stress urinary incontinence post-TOS placement is the lengthening of the vesicourethral anastomosis to bulbar-urethra distance. This is the first such study utilizing dynamics MRI in post prostatectomy controls, incontinent pre-TOS, and post-TOS to assess and show these findings.

AB - The goal of this manuscript is to assess data suggesting that intravitreal injection of anti-vascular endothelial growth factors (anti-VEGFs) could result in systemic adverse events (AEs). The class-specific systemic AEs should be similar to those encountered in cancer trials. The most frequent AE observed in oncology, hypertension and proteinuria, should thus be the most common expected in ophthalmology, but their severity should be lower because of the much lower doses of anti-VEGFs administered intravitreally. Such AEs have not been frequently reported in ophthalmology trials. In addition, pharmacokinetic and pharmacodynamic data describing systemic diffusion of anti-VEGFs should be interpreted with caution because of significant inconsistencies reported. Thus, safety data reported in ophthalmology trials and pharmacokinetic/pharmacodynamic data provide robust evidence that systemic events after intravitreal injection are very unlikely. Additional studies are needed to explore this issue further, as much remains to be understood about local and systemic side effects of anti VEGFs.

PMID- 29567023 TI - Strategies for enhancing microbial tolerance to inhibitors for biofuel production: A review. AB - Using lignocellulosic biomass for the production of renewable biofuel provides a sustainable and promising solution to the crisis of energy and environment. However, the processes of biomass pretreatment and biofuel fermentation bring a variety of inhibitors to microbial strains. These inhibitors repress microbial growth, decrease biofuel yields and increase fermentation costs. The production of biofuels from renewable lignocellulosic biomass relies on the development of tolerant and robust microbial strains. In recent years, the advancement of tolerance engineering and evolutionary engineering provides powerful platform for obtaining host strains with desired tolerance for further metabolic engineering of biofuel pathways. In this review, we summarized the inhibitors derived from biomass pretreatment and biofuel fermentation, the mechanisms of inhibitor toxicity, and the strategies for enhancing microbial tolerance. PMID- 29567024 TI - Jejunal arterial access for retrograde mesenteric stenting. AB - Endovascular approaches have replaced open surgical revascularization in most patients with mesenteric ischemia; however, flush ostial occlusions may not be amenable to traditional antegrade access. Retrograde mesenteric stenting has been previously described, but this technique requires a formal laparotomy and dissection of the proximal superior mesenteric artery. We present here a modification of this technique that requires only a "mini-laparotomy" and no open vascular repair of the superior mesenteric artery as well as a review of our initial institutional experience with this procedure. Our approach differs from previously described work by minimizing mesenteric dissection, avoiding the need for repair of an arteriotomy, and limiting the size of the laparotomy incision in this population of profoundly comorbid patients.

The aim of this study was to investigate thoracic endovascular aortic repair (TEVAR) outcomes in patients with confirmed or suspected syndromic and nonsyndromic genetically triggered thoracic aortic dissection. METHODS: We analyzed data for patients with descending thoracic aorta (DTA) dissection treated with TEVAR from the National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC). Enrolled patients had confirmed (syndromic or familial) or suspected genetically triggered thoracic aortic disease. The latter group includes patients with sporadic aortic dissection presenting at 50 years of age or younger in the absence of a family history or syndromic features. RESULTS: Between 2006 and 2014, there were 371 patients with DTA dissection enrolled in GenTAC. TEVAR was performed in 31 cases (58.1% male; median age, 47 years; range, 21.3-65.6 years). Genetically triggered aortic dissection was confirmed in 18 cases, and an additional 13 cases had suspected genetically triggered dissection because of early onset of presentation. TEVAR was performed in nine patients with type A aortic dissection: five in conjunction with acute type A dissection repair and four in the chronic phase to treat aneurysmal degeneration of the residual dissected DTA (median interval to TEVAR, 2.1 years). TEVAR was also performed in 22 cases of type B aortic dissection (TBAD), 12 acute and 10 chronic (median interval to TEVAR, 1.6 years). There were no perioperative deaths. Median follow up for all cases was 2 years (range, 0.4 month-7 years). Reinterventions after TEVAR were performed in 13 cases (41.9%). This included urgent repair of three retrograde ascending aorta dissections occurring after TEVAR for acute TBAD (25%) and seven thoracoabdominal repairs with stent graft explantation (22.6%) at a median of 7 months after TEVAR (range, 1-16.6 months). CONCLUSIONS: TEVAR in patients with genetically triggered aortic dissections can be lifesaving in the acute setting though associated with high risk of retrograde aortic dissection in acute TBAD. For chronic dissection-related DTA aneurysmal degeneration, TEVAR could potentially be lifesaving in patients deemed too high risk for open surgical repair. Close postoperative surveillance is required, given the risk of subsequent device failure and need for reintervention. Because these circumstances are rare, multicenter prospective enrollment of patients with genetically triggered aortic disease is essential to delineate the indications for and risks of TEVAR in this heterogeneous population. PMID- 29567026 TI - Serum tumor necrosis factor alpha levels are associated with new ischemic brain lesions after carotid artery stenting. AB - OBJECTIVE: New diffusion-weighted imaging (DWI) lesions on magnetic resonance imaging (MRI) after carotid artery stenting (CAS) are associated with an increased risk of future cerebrovascular events. Therefore, we evaluated the association between the expression levels of serum inflammatory markers and new DWI lesions after CAS and the presence of intraplaque hemorrhage (IPH). We also explored the mechanisms underlying this association. METHODS: A total of 225 inpatients with severe carotid artery stenosis were consecutively enrolled in this cohort study. Serum inflammatory marker levels were detected in all patients by enzyme-linked immunosorbent assay. In the final analysis, 128 patients who underwent CAS and received pretreatment and post-treatment MRI scans were enrolled. DWI was performed to detect new ischemia brain lesions. T1-weighted, T2 weighted, and time-of-flight sequences were also conducted to identify IPH. RESULTS: Serum tumor necrosis factor alpha (TNF-alpha) levels were significantly higher in symptomatic patients as well as in IPH+ patients identified by carotid MRI. New DWI lesions were identified in 50% of patients after CAS. Univariate analysis showed that DWI+ patients after CAS exhibited older mean age, higher mean TNF-alpha levels, and more IPH on preoperative MRI and were less likely to have right carotid stenosis than DWI- patients. Multivariate logistic regression analyses revealed that serum TNF-alpha concentrations were associated with new DWI lesions after CAS (odds ratio, 1.245; 95% confidence interval, 1.068-1.451; P = .005). Finally, the specificity and sensitivity of serum TNF-alpha levels in predicting DWI+ patients after CAS were 0.828 and 0.453, respectively. CONCLUSIONS: Higher serum TNF-alpha levels are associated with a higher likelihood of new DWI lesions after CAS and the presence of IPH. Therefore, TNF alpha is a potentially valuable predictor of acute ischemic cerebral lesions after CAS and the presence of IPH. PMID- 29567027 TI - A prospective randomized study of bovine carotid artery biologic graft and expanded polytetrafluoroethylene for permanent hemodialysis access. AB - OBJECTIVE: Arteriovenous grafts (AVGs) remain reliable substitutes for permanent hemodialysis access in scenarios that preclude the placement of native arteriovenous fistulas (AVFs). The majority of AVGs are constructed of expanded polytetrafluoroethylene (ePTFE), which is relatively inexpensive and readily available, but synthetic AVGs have poor patency rates. On the other hand, biologic grafts confer an advantage by virtue of their inherent similarity to the native human vasculature. However, evidence to support the current preference of synthetic conduits over biologic grafts in clinical practice is scarce. The aim of this protocol is to propose a contemporary re-evaluation and comparison between ePTFE and bovine carotid artery (BCA) grafts. METHODS: This prospective randomized controlled trial is being conducted at an academic hospital center. A total of 100 patients at least 18 years of age and undergoing AVG placement will be recruited and prospectively randomized into two parallel groups with a 1:1 allocation ratio. Patients eligible to receive AVF and those with a known allergic reaction or history of intolerance to any ePTFE or BCA component will not be included in the study. Moreover, patients with a recent active infection at the site of previous AVG placement and patients with a bleeding disorder, an active malignant disease, or a life expectancy <1 year or who refuse blood transfusion and pregnant women will be excluded. Patients will receive either BCA (experimental) or standard ePTFE grafts (control) in compliance with the National Kidney Foundation Kidney Disease Outcomes Quality Initiative guidelines for AVG creation. Primary end points include primary, primary assisted, secondary, and functional patency at 1 year and 2 years after graft placement. Secondary outcomes include complications (pseudoaneurysms, infections, and steal syndrome) and reintervention rates during the first and second postoperative years. Outcomes will be assessed and documented every 6 months. RESULTS: Once the study is completed, analysis of the data will be performed using univariate methods, and Kaplan-Meier and multivariate Cox proportional regression analyses will be employed to evaluate and to compare outcomes between BCA and ePTFE over time. CONCLUSIONS: The creation of a functional and durable dialysis vascular access is crucial in the treatment of patients with end-stage renal disease and is a challenging quest for vascular surgeons. The proposed study compares the outcomes of synthetic and biologic AVG options in patients who are poor candidates for a native AVF. This will help derive contemporary evidence and improve the care of vascular access patients. PMID- 29567028 TI - Analysis of host Toll-like receptor 3 and RIG-I-like receptor gene expression in patients with abdominal aortic aneurysm. AB - OBJECTIVE: Abdominal aortic aneurysm (AAA) is a vascular disease relatively common in the elderly population. Although some events that contribute to the development and progression of AAA are known, there are limited data examining the association of Toll-like receptor 3 (TLR3) and RIG-I-like receptor expression with the pathogenesis of AAAs. In this study, we investigated the gene and protein expression of TLR3 and RIG-I-like receptors (RIG-I and MDA5) in aortic wall and blood of AAA patients and examined the relationship between their expression and immune response. METHODS: Total RNA was extracted from aortic wall tissues and blood samples collected from 20 patients with AAA and blood samples of 17 healthy volunteers without aortic aneurysm. To evaluate the DDX58 (RIG-I), IFIH1 (MDA5), and TLR3 gene expression level, quantitative real-time polymerase chain reaction was used. Extracellular cytokine and pattern recognition receptor levels were quantified by enzyme-linked immunosorbent assays. RESULTS: TLR3, RIG I, and MDA5 were constitutively expressed in both aortic tissues and blood samples from AAA patients and healthy volunteers. In patients with AAA, higher TLR3 expression in aortic tissues than in blood was found (P = .004). The DDX58 messenger RNA expression was higher in blood of patients with AAA compared with healthy subjects (P = .021). A significantly higher level of plasma interleukin 4 was noticed in patients with AAA than in healthy individuals (P = .008). CONCLUSIONS: This study suggests that RIG-I and TLR3 seem to be important factors in the pathogenesis of AAA. PMID- 29567029 TI - Through-knee amputation is a feasible alternative to above-knee amputation. AB - OBJECTIVE: Through-knee amputation (TKA) is a rare amputation performed in <2% of all major lower extremity amputations in the United States. Despite biomechanical benefits and improved rehabilitation compared with above-knee amputation (AKA), TKA has largely been abandoned by vascular surgeons because of concerns for poor wound healing. The purpose of this study was to evaluate surgical outcomes of TKA. METHODS: The American College of Surgeons National Surgical Quality Improvement Program between 2005 and 2012 was queried using Current Procedural Terminology codes indicating AKA and TKA. Baseline characteristics were reviewed, and logistic regression analysis was performed to identify predictors of 30-day mortality. Propensity score matching was used to balance comorbidities between AKA and TKA. Operative variables and postoperative complications were compared between the groups. RESULTS: A total of 7469 AKA and 251 TKA patients were identified among 15,932 major lower extremity amputations. Baseline characteristics were examined. White race, chronic obstructive pulmonary disease, dyspnea, emergent operation, steroid use, myocardial infarction, congestive heart failure, high American Society of Anesthesiologists score, old age, preoperative sepsis or septic shock, and dialysis dependency were associated with increased 30 day mortality. Independent lifestyle and smoking (within 1 year) were protective against early death. Baseline comorbidities were not statistically significant after 1:1 propensity score matching. Operative outcomes were similar in both groups (AKA vs TKA). Wound infection (7.2% vs 11.2%; P = .16), dehiscence rate (1.2% vs 0.8%; P = 1.0), and 30-day mortality (9.6% vs 11.2%; P = .66) were comparable. Other outcome parameters, including cardiopulmonary and genitourinary complications, were similar except for a higher likelihood of return to the operating room in the TKA group (27.9% vs 12.4%; P < .01). Postoperative mortality was not associated with TKA (P = .77) or reoperation (P = .42), but it was associated with the patients' physiologic conditions (dyspnea, sepsis, emergent operation, high American Society of Anesthesiologists score, and dependent lifestyle). Predictors of reoperation were contaminated wound (hazard ratio [HR], 2.19; confidence interval [CI], 1.17-3.23; P = .015), sepsis or septic shock (HR, 2.63; CI, 1.37-5.05; P = .004), chronic obstructive pulmonary disease (HR, 2.81; CI, 1.23-6.42; P = .014), and wound infection (HR, 4.91; CI, 2.06-11.70; P < .001). Presence of peripheral vascular disease was not associated with post-TKA reoperation (P = .073). CONCLUSIONS: TKA demonstrated similar postoperative morbidity and mortality compared with AKA. Wound infection and risk of dehiscence were equivalent. TKA did demonstrate a higher rate of reoperation; however, neither TKA nor reoperation predicted postoperative mortality. Patients in stable physiologic condition without active infection can safely undergo elective TKA to maximize rehabilitation potential. PMID- 29567030 TI - Comparison of 4 commercial kits for the extraction of circulating DNA from plasma. AB - The utility of circulating DNA as a source of clinical biomarkers in blood is limited by its low concentration and small fragment size. Effective purification methods can maximize circulating DNA yield and contribute to the success of downstream protocols. We describe the evaluation of 4 commercial DNA purification kits-QIAamp Circulating Nucleic Acids kit, QIAamp DNA Blood Mini kit, QIAamp Ultrasens Virus kit and the QIASymphony DSP Virus kit-for the extraction of high and low molecular weight DNA from blood plasma. Using qPCR to quantitate endogenous Alu sequences, as well as spiked exogenous high and low molecular weight zebrafish DNA, we found that the Circulating Nucleic Acids kit and the DSP kit were both efficient at purifying DNA from plasma regardless of fragment size, whereas the DNA Blood Mini kit was only able to effectively extract high molecular weight DNA. The Ultrasens Virus Kit produced the lowest yields for both large and small fragments. The use of carrier RNA with the Circulating Nucleic Acids and the DSP kits improved yields. Appropriate choice of kit can be an important factor in determining experiment outcome. PMID- 29567031 TI - Crisis of antibiotics: Health professionals, citizens and politicians, we are all responsible. PMID- 29567032 TI - The future control of rotavirus disease: Can live oral vaccines alone solve the rotavirus problem? AB - Live oral rotavirus (RV) vaccines used worldwide are most effective in reducing diarrheal hospitalizations from RV in high income countries and least effective in low income countries where RV remains a prime cause of death in children. Research has failed to fully explain the reason for this difference of efficacy for RV vaccines, an observation made with other live oral vaccines for polio, cholera and typhoid fever. Use of parenteral vaccines have been successful in overcoming this problem for both polio and typhoid and parenteral RV vaccines are now in development. This approach should be pursued for rotavirus vaccine as well because in low income countries where oral RV vaccines have been introduced and are only partially effective, RV remains the most common cause of diarrhea in children under 5 years. The ultimate control of RV diarrheal will likely require both oral and parenteral vaccines. PMID- 29567033 TI - Recombinant NADP-dependent isocitrate dehydrogenase of Edwardsiella tarda induces both Th1 and Th2 type immune responses and evokes protective efficacy against edwardsiellosis. AB - Edwardsiella tarda has become one of the most severe fish pathogens throughout the world. Thus, studies on the design and production of highly protective vaccines against this pathogen, as well as the mechanisms of vaccine-induced disease resistance are urgently needed. In this study, the NADP-dependent isocitrate dehydrogenase (IDH) of E. tarda was recombinantly expressed and flounder (Paralichthys olivaceus) anti-rIDH serum was prepared. Also, the outer membrane proteins (OMPs) of E. tarda were extracted and analyzed by western blotting. The results showed that flounder anti-rIDH serum could specifically recognize a 44 kDa protein of E. tarda OMPs, which was identified to be the native IDH of E. tarda by mass spectrometric. Consistently, immunogold electron microscopy showed that IDH could be detected on the membrane of E. tarda. Then, the vaccine potential of rIDH was tested in a flounder model, and the results showed that rIDH produced a relative percent survival (RPS) of 73.3%, which was significantly higher than that produced by formalin killed E. tarda cells. Immunological analysis showed that rIDH could induce the proliferation of rIDH specific sIg+ lymphocytes, which resulted in the production of anti-E. tarda antibodies. Accordingly, serum bactericidal activity assay showed that the serum of rIDH vaccinated fish exhibited the highest bactericidal activity compared with other groups. qRT-PCR analysis showed that rIDH could enhance the expressions of IFN-gamma, NKEF, IL-6, MHCIalpha, CD4-1 and CD8alpha. Moreover, the bacterial burden was also detected in vaccinated fish after challenge, which showed that the number of E. tarda cells in spleen of rIDH group was significantly lower than other groups. All these results suggested that rIDH is a promising vaccine candidate against E. tarda infection. PMID- 29567034 TI - Squalene containing solid lipid nanoparticles, a promising adjuvant system for yeast vaccines. AB - Potent adjuvant systems are required for subunit and single antigen based vaccines to provide sufficient immunogenicity. Furthermore, adjuvants can reduce the required number of immunisations and the antigen amount. Squalene nanoemulsions, like MF59(r) and AddaVaxTM, are potent, safe and well characterised adjuvant systems and approved for use in humans. Here, we developed squalene containing solid lipid nanoparticles, which can be sterilised by steam sterilisation and stored as freeze-dried power together with a yeast-based vaccine. Detailed size measurements using dynamic and static light scattering were applied, as the immune stimulating effect of squalene emulsions is mainly dependent on the particle size. The size range of AddaVaxTM (120-170 nm) was favoured for the developed squalene containing solid lipid nanoparticles. Differential scanning calorimetry (DSC) and H NMR studies were performed to characterise the interactions of the incorporated liquid squalene with the solid hard fat matrix. A homogeneous distribution as liquid domains in the solid glyceride structure was suggested for the liquid squalene. The developed adjuvant was compared with Freund's adjuvant and a commercially available squalene nanoemulsion in a vaccine trial in the mouse model with a yeast-based vaccine directed against the infectious bursal disease virus. All squalene-based adjuvants showed excellent biocompatibility and provided immune stimulating properties comparable to Freund's adjuvant. PMID- 29567035 TI - Knowledge, attitudes, and practices regarding hepatitis B vaccination among hospital-based doctors and nurses in China: Results of a multi-site survey. AB - BACKGROUND: Hepatitis B virus (HBV) can cause chronic HBV infection, which may lead to advanced cirrhosis and liver cancer. Healthcare workers (HCWs) are at risk HBV infection as an occupational hazard. Hepatitis B vaccination of HCWs is recommended by WHO, but the status of hepatitis B vaccination among HCWs in China is seldom reported. METHODOLOGY: We conducted a cross-sectional study in 22 hospitals of 3 developed cities in China. We interviewed managers in infectious diseases and occupational health departments, and at least 40 HCWs per hospital. RESULTS: We interviewed 929 HCWs; 80.8% were vaccinated against hepatitis B and 96.7% were willing to be vaccinated; 38.2% of HCWs reported having at least one needle stick or sharps injury. Three hospitals provide free hepatitis B vaccination for HCWs; hospitals with a hepatitis B vaccination policy, more HCWs reported being vaccinated (91.7% vs 79.0%, P < 0.001). HCWs in high risk departments (P = 0.011), with more knowledge of hepatitis B vaccine (P < 0.001), and with fewer working years (P = 0.002) were more likely to be vaccinated against HBV. Infectious diseases and occupational health managers had positive attitudes towards hepatitis B vaccination. CONCLUSIONS: Hepatitis B vaccination was well accepted among HCWs. Hospital provision of free vaccine, greater HCW knowledge of HBV, and working in higher-risk settings were associated with being vaccinated. A national policy of offering hepatitis B vaccine to HCWs should be considered in China. Provision of free hepatitis B vaccine for HBsAb negative HCWs may be acceptable. Education about HBV and hepatitis B vaccine may help promote policy implementation. PMID- 29567037 TI - Resurfacing hemiarthroplasty of the shoulder for patients with juvenile idiopathic arthritis. AB - BACKGROUND: This study reports the outcome of resurfacing hemiarthroplasty (RHA) in a cohort of patients with juvenile idiopathic arthritis (JIA) affecting the shoulder joint METHODS: Fourteen uncemented RHA procedures were performed for 11 consecutive patients who required surgery because of JIA. Mean age at surgery was 36.4 years. Mean clinical follow-up was 10.4 years (range, 5.8-13.9 years). A significant humeral head defect (up to 40% surface area) was found in 5 shoulders and filled with autograft from the distal clavicle or femoral head allograft. RESULTS: At latest follow-up, no patient required revision. There was excellent relief from pain. The mean Oxford Shoulder Score and Constant-Murley Score improved significantly. No shoulder had a poor outcome, and 6 had a very good or excellent outcome. Worse outcome was associated with an intraoperative finding of significant humeral head erosion. Two shoulders required early arthroscopic subacromial decompression, but there were no other reoperations. There were no instances of radiographic implant loosening or proximal migration. Painless glenoid erosion was seen in 5 shoulders but was not associated with worse outcome. CONCLUSIONS: The midterm results of RHA for JIA are at least comparable to those for stemmed hemiarthroplasty, with the added benefit of bone conservation. PMID- 29567036 TI - Fibrocartilaginous metaplasia identified in the long head of the biceps brachii. AB - BACKGROUND: In the glenohumeral joint, the long head of biceps brachii (LHBB) is exposed to tension and compression loading. The short head of biceps brachii (SHBB) works only in tension. It is known that tendon under compression might develop fibrocartilaginous metaplasia that improves the resistance to compression but reduces the resistance to tension. This study evaluated the presence of cartilage in LHBB and SHBB samples, supporting its possible role in tendon tear. METHODS: Between 2014 and 2016, 13 samples of LHBB and SHBB were collected during surgery for shoulder instability, glenohumeral arthritis, and massive rotator cuff tears. The samples were stained with hematoxylin and eosin, safranin-O, and Alcian blue (pH 1.0) for light microscopy. Immunohistochemistry was performed using anti-S100, anti-collagen I and II, and anti-tenascin-C antibodies. RESULTS: Histochemistry: LHBB samples showed matrix disorganization, with clusters of chondrocyte surrounded by collagen fibers and glycosaminoglycans. Safranin-O showed evident metachromasia. SHBB samples did not show any matrix disorganization or cartilaginous metaplasia. Immunohistochemistry: In all LHBB samples, anti-S100 and anti-collagen II showed cartilage in proximity of the tendon tear. Tenascin C immunostained closely to the disorganized matrix areas. SHBB, however, showed no positive areas for S-100, anti-collagen II, or tenascin C. CONCLUSIONS: According to our results, we hypothesize that the repeated stimulation in compression may induce the formation of fibrous cartilage. However, to date its role in tendon pathology remains to be clearly defined. PMID- 29567038 TI - Validating the Patient Reported Outcomes Measurement Information System (PROMIS) computerized adaptive tests for upper extremity fracture care. AB - BACKGROUND: Computerized adaptive testing (CAT) for patient-reported outcomes (PROs) is a developing area within orthopedic surgery. Our objective was to validate the Patient Reported Outcomes Measurement Information System (PROMIS) CATs for upper extremity fracture care. We sought to correlate PROMIS with legacy PROs and to investigate floor and ceiling effects. METHODS: Patients who underwent open reduction and internal fixation of upper extremity trauma were prospectively enrolled. Legacy PROs included the visual analog scale for pain, the Disabilities of the Arm, Shoulder and Hand questionnaire, the University of California-Los Angeles Shoulder Rating Scale, the Mayo Elbow Performance Score, and the 36-Item Short Form Health Survey. PROMIS CATs included Physical Function (PROMIS PF), PROMIS Pain Interference (PROMIS Pain), and PROMIS Upper Extremity (PROMIS UE). Correlations between the PROs were calculated as were the absolute and relative floor and ceiling effect. RESULTS: The study prospectively enrolled 174 patients with upper extremity trauma. There was moderate to high correlation between PROMIS UE CAT and legacy upper extremity-specific PROs (rho = 0.42-0.79), and high correlation between the PROMIS PF CAT and the 36-Item Short Form Health Survey Physical Component Summary (rho = 0.71, P < .001). The visual analog scale for pain, University of California-Los Angeles Shoulder Rating Scale, Constant Score, and Mayo Elbow Score demonstrated a significant absolute ceiling effect (20.5%-23.7%), whereas the PROMIS PF, PROMIS UE, and PROMIS Pain CATs demonstrated no absolute ceiling effect. CONCLUSION: PROMIS PF, Pain, and UE correlate well with legacy PROs in a upper extremity trauma population, with less absolute floor or ceiling effects. This study provides preliminary evidence for the utility of PROMIS CATs in upper extremity trauma patients.

AB - PURPOSE: To investigate mean ocular refraction (MOR) and astigmatism, over the human age range and compare severity of refractive error to earlier studies from clinical populations having large age ranges. METHODS: For this descriptive study patient age, refractive error and history of surgery affecting refraction were abstracted from the Waterloo Eye Study database (WatES). Average MOR, standard deviation of MOR and astigmatism were assessed in relation to age. Refractive distributions for developmental age groups were determined. MOR standard deviation relative to average MOR was evaluated. Data from earlier clinically based studies with similar age ranges were compared to WatES. RESULTS: Right eye refractive errors were available for 5933 patients with no history of surgery affecting refraction. Average MOR varied with age. Children <1 yr of age were the most hyperopic (+1.79D) and the highest magnitude of myopia was found at 27yrs ( 2.86D). MOR distributions were leptokurtic, and negatively skewed. The mode varied with age group. MOR variability increased with increasing myopia. Average astigmatism increased gradually to age 60 after which it increased at a faster rate. By 85+ years it was 1.25D. J0 power vector became increasingly negative with age. J45 power vector values remained close to zero but variability increased at approximately 70 years. In relation to comparable earlier studies, WatES data were most myopic. CONCLUSIONS: Mean ocular refraction and refractive error distribution vary with age. The highest magnitude of myopia is found in young adults. Similar to prevalence, the severity of myopia also appears to have increased since 1931. PMID- 29567042 TI - Face and content validity of variables associated with the difficult-to-sedate child in the paediatric intensive care unit: A survey of paediatric critical care clinicians. AB - BACKGROUND: Clinicians recognise that some critically ill children are difficult to-sedate. It may be possible to identify this clinical phenotype for sedation response using statistical modelling techniques adopted from machine learning. This requires identification of a finite number of variables to include in the statistical model. OBJECTIVE: To establish face and content validity for 17 candidate variables identified in the international literature as characteristic of the difficult-to-sedate child phenotype. METHODS: Paediatric critical care clinicians rated the relevance of 17 variables characterising the difficult-to sedate child using a four-point scale ranging from not (1) to highly relevant (4). Face and content validity of these variables were assessed by calculating a mean score for each item and computing an item-level content validity index. Items with a mean score >1 were rated as having adequate face validity. An item level content validity index >=0.70 indicated good to excellent content validity. SETTING AND PARTICIPANTS: Web-based survey emailed to members of the Pediatric Acute Lung Injury and Sepsis Investigators Network or the Society of Critical Care Medicine Pediatric Sedation Study Group. RESULTS: Of 411 possible respondents, 121 useable surveys were returned for a response rate of 29%. All items had a mean score >1, indicating adequate face validity. Ten of 17 items scored an item-level content validity index >=0.70. The highest scoring items were requiring three or more sedation classes simultaneously, daily modal sedation score indicating agitation, sedation score indicating agitation for 2 consecutive hours, receiving sedatives at a dose >90th percentile of the usual starting dose, and receiving intermittent paralytic doses for sedation. CONCLUSIONS: Computation of an item-level content validity index validated variables to include in statistical modelling of the difficult-to-sedate phenotype. The results indicate consensus among paediatric critical care clinicians that the majority of candidate variables identified through literature review are characteristic of the difficult-to-sedate child.

AB - We report a novel method for in situ imaging of microvascular permeability in inflamed gingival tissue, using state-of-the-art CellvizioTM intravital endoscopic technology and a mouse model of ligature-induced periodontitis. The silk ligature was first placed at the upper left second molar. Seven days later, the ligature was removed, and the animals were intravenously injected with Evans blue. Evans blue dye, which selectively binds to blood albumin, was used to monitor the level of inflammation by monitoring vascular permeability in control non-diseased and ligature-induced experimental periodontitis tissue. More specifically, leakage of Evans blue-bound albumin from the micro-capillary to connective tissue indicates the state of inflammation occurring in the specific site. Evans blue leakage from blood vessels was imaged in situ by directly attaching the endoscope (mini Z tip) of the CellvizioTM system to the gingival tissue without any surgical incision. Evans blue emission intensity was significantly elevated in gingiva of periodontitis lesions, but not control non ligature placed gingiva, indicating that this technology can be used as a potential minimally invasive diagnostic tool to monitor the level of inflammation at the periodontal disease site.

AB - BACKGROUND: Postoperative pancreatic fistula (POPF) is a severe complication of the pancreaticoduodenectomy (PD). Recently, we introduced a method of suspender pancreaticojejunostomy (PJ) to the PD. In this study, we retrospectively analyzed various risk factors for complications after PD. We also introduced and assessed the suspender PJ to demonstrate its advantages. METHODS: Data from 335 patients with various periampullary lesions, who underwent the Whipple procedure (classic Whipple procedure or pylorus-preserving) PD by either traditional end-to-side invagination PJ or suspender PJ, were analyzed. The correlation between either perioperative or postoperative complications and corresponding PD approaches was evaluated by univariate analysis. RESULTS: A total of 147 patients received the traditional end-to-side invagination PJ, and 188 patients were given the suspender PJ. Overall, 51.9% patients had various complications after PD. The mortality rate was 2.4%. The POPF incidence in patients who received the suspender PJ was 5.3%, which was significantly lower than those who received the traditional end-to-side invagination PJ (18.4%) (P < 0.001). Univariate analysis showed that PJ approach and the pancreas texture were significantly associated with the POPF incidence rate (P < 0.01). POPF was a risk factor for both postoperative abdominal cavity infection (OR = 8.34, 95% CI: 3.99-17.42, P < 0.001) and abdominal cavity hemorrhage (OR = 4.86, 95% CI: 1.92-12.33, P = 0.001). CONCLUSIONS: Our study showed that the impact of the pancreas texture was a major risk factor for pancreatic leakage after a PD. The suspender PJ can be easily accomplished and widely applied and can effectively decrease the impact of the pancreas texture on pancreatic fistula after a PD and leads to a lower POPF incidence rate. PMID- 29567047 TI - Augmented reality technology for preoperative planning and intraoperative navigation during hepatobiliary surgery: A review of current methods. AB - BACKGROUND: Augmented reality (AR) technology is used to reconstruct three dimensional (3D) images of hepatic and biliary structures from computed tomography and magnetic resonance imaging data, and to superimpose the virtual images onto a view of the surgical field. In liver surgery, these superimposed virtual images help the surgeon to visualize intrahepatic structures and therefore, to operate precisely and to improve clinical outcomes. DATA SOURCES: The keywords "augmented reality", "liver", "laparoscopic" and "hepatectomy" were used for searching publications in the PubMed database. The primary source of literatures was from peer-reviewed journals up to December 2016. Additional articles were identified by manual search of references found in the key articles. RESULTS: In general, AR technology mainly includes 3D reconstruction, display, registration as well as tracking techniques and has recently been adopted gradually for liver surgeries including laparoscopy and laparotomy with video-based AR assisted laparoscopic resection as the main technical application. By applying AR technology, blood vessels and tumor structures in the liver can be displayed during surgery, which permits precise navigation during complex surgical procedures. Liver transformation and registration errors during surgery were the main factors that limit the application of AR technology. CONCLUSIONS: With recent advances, AR technologies have the potential to improve hepatobiliary surgical procedures. However, additional clinical studies will be required to evaluate AR as a tool for reducing postoperative morbidity and mortality and for the improvement of long-term clinical outcomes. Future research is needed in the fusion of multiple imaging modalities, improving biomechanical liver modeling, and enhancing image data processing and tracking technologies to increase the accuracy of current AR methods. PMID- 29567048 TI - [Central venous access for cancer chemotherapy]. AB - The tip of a long term central venous access should be located at the junction of the superior vena cava with the right atrium in order to reduce the incidence of dysfunction and venous thromboses. Picc-lines have their place for treatments of less than 6 months with obvious advantages in terms of discretion and comfort. Long-term sequential chemotherapy is an indisputable indication of an implantable port, while long-term parenteral nutrition is an indication of a tunneled cuffed catheter. In case of mediastinal compression, the risk-benefit ratio favors femoral access. Catheter related venous thrombosis or infection do not necessarily require the withdrawal of the device.

AB - OBJECTIVES: Computerized detection of voice disorders has attracted considerable academic and clinical interest in the hope of providing an effective screening method for voice diseases before endoscopic confirmation. This study proposes a deep-learning-based approach to detect pathological voice and examines its performance and utility compared with other automatic classification algorithms. METHODS: This study retrospectively collected 60 normal voice samples and 402 pathological voice samples of 8 common clinical voice disorders in a voice clinic of a tertiary teaching hospital. We extracted Mel frequency cepstral coefficients from 3-second samples of a sustained vowel. The performances of three machine learning algorithms, namely, deep neural network (DNN), support vector machine, and Gaussian mixture model, were evaluated based on a fivefold cross-validation. Collective cases from the voice disorder database of MEEI (Massachusetts Eye and Ear Infirmary) were used to verify the performance of the classification mechanisms. RESULTS: The experimental results demonstrated that DNN outperforms Gaussian mixture model and support vector machine. Its accuracy in detecting voice pathologies reached 94.26% and 90.52% in male and female subjects, based on three representative Mel frequency cepstral coefficient features. When applied to the MEEI database for validation, the DNN also achieved a higher accuracy (99.32%) than the other two classification algorithms. CONCLUSIONS: By stacking several layers of neurons with optimized weights, the proposed DNN algorithm can fully utilize the acoustic features and efficiently differentiate between normal and pathological voice samples. Based on this pilot study, future research may proceed to explore more application of DNN from laboratory and clinical perspectives. PMID- 29567050 TI - The 2016 G. Paul Moore Lecture: Lessons in Voice Rehabilitation: Journal of Voice and Clinical Practice. AB - This Paul Moore Lecture honors the contributions made by authors to the Journal of Voice during a period of 30 years, from 1987. Fifty articles were selected and included under the following five topics: (1) normalcy of the larynx and voice; (2) the clinical speech-language pathologist's evaluation; (3) the patient's perspective; (4) the core of vocal rehabilitation; and (5) behavioral versus organic dysphonias. The analysis reflects a vivid landscape of the specific area and significant advances in knowledge. It also shows the valuable interdependence between science and clinical practice. The topics highlight the following information: (1) The physical appearance of a healthy larynx varies across individuals with normal voices. (2) The voice is not a binary descriptor (normal versus abnormal) but a variable measure, with many cultural influences on the perceptual auditory analysis of a voice. (3) The clinical speech-language pathologist assessment is multidimensional and multiparametric, with both subjective and objective analyses. The patients' opinion about the impact of a voice problem on his or her quality of life is significant when proposing a treatment. Therefore, it is also included in the initial assessment. (4) Vocal rehabilitation is a nonlinear process that combines direct and indirect approaches. Evidence of the positive effect of voice therapy is now well established. (5) Behavioral dysphonias may be linked to self-regulation of the use of voice and this needs to be taken into consideration. Although organic dysphonias are not necessarily the result of harmful vocal behaviors, they too can benefit from vocal rehabilitation. PMID- 29567051 TI - Effects of Therapy With Semi-occluded Vocal Tract and Choir Training on Voice in Adult Individuals With Congenital, Isolated, Untreated Growth Hormone Deficiency. AB - OBJECTIVES: Voice is produced by the vibration of the vocal folds expressed by its fundamental frequency (Hz), whereas the formants (F) are fundamental frequency multiples, indicating amplification zones of the vowels in the vocal tract. We have shown that lifetime isolated growth hormone deficiency (IGHD) causes high pitch voice, with higher values of most formant frequencies, maintaining a prepuberal acoustic prediction. The objectives of this work were to verify the effects of the therapy with a semi-occluded vocal tract (SOVTT) and choir training on voice in these subjects with IGHD. We speculated that acoustic vocal parameters can be improved by SOVTT or choir training. STUDY DESIGN: This is a prospective longitudinal study without control group. METHODS: Acoustic analysis of isolated vowels was performed in 17 adults with IGHD before and after SOVTT (pre-SOVTT and post-SOVTT) and after choir training (post training), in a 30-day period. RESULTS: The first formant was higher in post training compared with the pre-SOVTT (P = 0.009). The second formant was higher in post-SOVTT than in pre-SOVTT (P = 0.045). There was a trend of reduction in shimmer in post-choir training in comparison with pre-SOVTT (P = 0.051), and a reduction in post-choir training in comparison with post-SOVTT (P = 0.047). CONCLUSIONS: SOVTT was relevant to the second formant, whereas choir training improved first formant and shimmer. Therefore, this speech therapy approach was able to improve acoustic parameters of the voice of individuals with congenital, untreated IGHD. This seems particularly important in a scenario in which few patients are submitted to growth hormone replacement therapy. PMID- 29567052 TI - The efficacy and safety of topical tranexamic acid: A systematic review and meta analysis. AB - Tranexamic acid (TXA) is an effective hemostatic agent used for the reduction of blood loss and transfusion. However, the safety profile of TXA remains in question due to a potential increased risk of venous thromboembolism. By applying TXA topically as opposed to intravenously, systemic absorption may be reduced and unwanted side-effects mitigated. The objective of our review is to investigate the efficacy and safety of topically applied tranexamic acid compared to both placebo, and the intravenous administration. Cochrane Central Register of Controlled Trials, MEDLINE, Embase, ISI Web of Science, PubMed, and Clinicaltrials.gov were searched from inception to November, 2016. We included randomized controlled trials that compared topical tranexamic acid to either placebo (or standard care) or intravenous administration, in adult patients. Surgical and non-surgical trials were included. Abstract, full-text selection, data extraction and risk of bias assessment were all performed in duplicate. In total, 67 studies involving 6,034 patients met inclusion criteria. The majority of trials evaluated orthopedic procedures. Compared to placebo, the administration of topical TXA significantly reduced the odds of receiving a blood transfusion (pooled OR 0.28, 95% CI 0.20 to 0.38; P < 0.001) and significantly reduced mean blood loss (WMD -276.6, 95% CI -327.8 to -225.4; P < 0.0001). When compared to the intravenous administration, there was no difference between the two groups in terms of transfusion requirements (pooled OR 1.03, 95% CI 0.72 to 1.46; P=0.88) or blood loss (WMD -21.95, 95% CI -66.61 to 27.71; P=0.34). There was no difference in the odds of developing a venous thromboembolic complication between the topical TXA and control groups (pooled OR=0.78, 95% CI 0.47 to 1.29; P=0.33) or the topical and intravenous groups (pooled OR=0.75, 95% CI 0.39 to 1.46; P=0.40). The topical application of TXA effectively reduces both transfusion risk and blood loss compared to placebo, without increasing thromboembolic risks. There were no major differences between topical and intravenous tranexamic acid with respect to safety and efficacy, and both were superior to placebo with regards to blood loss and transfusion requirements. Further study of the topical application is required outside of the field of orthopedics. PMID- 29567053 TI - Actinobacteria-Derived peptide antibiotics since 2000. AB - Members of the Actinobacteria, including Streptomyces spp., Kutzneria sp. Actinoplanes spp., Actinomycete sp., Nocardia sp., Brevibacteriumsp.,Actinomadura spp., Micromonospora sp., Amycolatopsis spp., Nonomuraea spp., Nocardiopsis spp., Marinactinospora sp., Rhodococcus sp., Lentzea sp., Actinokineospora sp., Planomonospora sp., Streptomonospora sp., and Microbacterium sp., are an important source of structurally diverse classes of short peptides of ~30 residues or fewer that will likely play an important role in new antibiotic development and discovery. Additionally, many have unique structures that make them recalcitrant to traditional modes of drug resistance via novel mechanisms, and these are ideal therapeutic tools and potential alternatives to current antibiotics. The need for novel antibiotic is urgent, and this review summarizes 199 Actinobacteria compounds published since 2000, including 35 cyclic lipopeptides containing piperazic or pipecolic acids, eight aromatic peptides, five glycopeptides, 21 bicyclic peptides, 44 other cyclic lipopeptides, five linear lipopeptides, six 2,5-diketopiperazines, one dimeric peptide, four nucleosidyl peptides, two thioamide-containing peptides, 25 thiopeptides, nine lasso peptides, and 34 typical cyclic peptides. The current and potential therapeutic applications of these peptides, including their structure, antituberculotic, antibacterial, antifungal, antiviral, anti-brugia, anti plasmodial, and anti-trypanosomal activities, are discussed. PMID- 29567054 TI - Electrical stimulation of the lower esophageal sphincter to address gastroesophageal reflux disease after sleeve gastrectomy. AB - BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) can result in de novo and worsen preexisting gastroesophageal reflux disease (GERD). Post-LSG patients with GERD refractory to proton pump inhibitors (PPI) usually undergo more invasive, anatomy-altering Roux-en-Y gastric bypass surgery. Lower esophageal sphincter (LES) electrical stimulation (ES) preserves the anatomy and has been shown to improve outcomes in GERD patients. OBJECTIVE: To evaluate the safety and efficacy of LES-ES in post-LSG patients with GERD not controlled with maximal PPI therapy. SETTING: Prospective, international, multicenter registry. METHODS: Patients with LSG-associated GERD partially responsive to PPI underwent LES-ES. GERD outcomes pre- and poststimulation were evaluated based on quality of life, esophageal acid exposure (after 6-12 mo), and PPI use. RESULTS: Seventeen patients (11 female, 65%), treated at 6 centers between May 2014 and October, 2016 with a median follow-up of 12 months (range 6-24), received LES-ES. Median age was 48.6 years (interquartile range, 40.5-56), median body mass index 31.7 kg/m2 (27.9-39.3). All patients were on at least daily PPI preoperatively; at last follow-up, 7 (41%) were completely off PPI, 5 (29%) took PPI on an intermittent basis, and 5 (29%) were on single-dose PPI. Median GERD-health-related quality of life scores improved from 34 (on-PPI, 25-41) at baseline to 9 (6-13) at last follow-up (off PPI, P<.001). Percentage of time with esophageal pH<4 improved from 13.2% (3.7 30.7) to 5.8% (1.1-54.4), P = .01. CONCLUSION: LES-ES in post-LSG patients suffering from symptomatic, PPI-refractory GERD resulted in significant improvement of GERD-symptoms, esophageal acid exposure, and need for PPI. Preserving the post-LSG anatomy, it offers a valid option for patients unable or unwilling to undergo Roux-en-Y gastric bypass surgery. PMID- 29567055 TI - Long-term follow-up of disease-specific quality of life after bariatric surgery. AB - BACKGROUND: Substantial improvements in health-related quality of life measured by generic questionnaires (most often the Short Form-36) have been noted over the long term in patients with morbid obesity who had undergone bariatric surgery. OBJECTIVES: To obtain long-term follow-up data on disease-specific quality of life in patients who underwent bariatric surgery (biliopancreatic diversion with duodenal switch) in 2007 to 2008. SETTING: Quebec Heart and Lung Institute, Quebec, Canada. METHODS: This study is a follow-up of the validation study, the Laval Questionnaire, an obesity-specific measure of health-related quality of life developed to be used in clinical trials. Patients who contributed to the validation study in 2007 to 2008 were administered the Laval Questionnaire again at long-term follow-up. RESULTS: Of 112 patients who contributed to the validation study, 90 were available for this long-term follow-up study (retention rate: 80%). Median follow-up was 8.8 years. For all 6 domains of the Laval Questionnaire, the improvements in quality-of-life scores were much larger than our best estimate of the minimal clinically important difference. In others, we observed some decline in quality-of-life scores over time after initial changes that occurred 1 to 2 years after surgery, during the so-called "honeymoon period." Improvements in quality of life were clearly related to surgery. CONCLUSION: This study confirms that bariatric surgery using biliopancreatic diversion with duodenal switch improves disease-specific quality of life in the short and long term. It also demonstrates that the Laval Questionnaire is responsive to treatment-induced changes. PMID- 29567056 TI - Psychological, behavioral, and weight-related aspects of patients undergoing reoperative bariatric surgery after gastric band: comparison with primary surgery patients. AB - BACKGROUND: Patients experiencing insufficient weight loss or weight regain in their first bariatric surgery may represent a high-risk group with greater problematic eating and general psychopathology levels, which may compromise the success of a reoperative procedure. OBJECTIVES: This study seeks to describe and compare disordered eating-related psychological and behavioral features of primary and reoperative surgery candidates after gastric band. SETTING: Hospital center and university in Portugal. METHODS: The baseline (preoperative) data from a longitudinal observational study are presented. Patients were interviewed by trained psychologists to identify binge-eating episodes and grazing and responded to a set of self-report measures: disordered eating, grazing, negative urgency, depression, anxiety, and stress. RESULTS: Two hundred twenty-five patients were undergoing primary surgery, and 166 were undergoing reoperative (REOP group) surgery. The groups did not differ in body mass index preoperatively, but the REOP group had greater weight suppression (t387 = -5.35, P = .001), higher highest (t387 = -3.40, P = .001) and lower lowest body mass index (t381 = 2.22, P = .03). The main reasons for reoperative surgery were weight regain/poor weight loss (42.8%) or medical complications (32.5%). REOP patients with objective binge eating reported a higher frequency of these episodes (t47 = 2.15, P = .04). No significant difference was found for the self-report measures assessed (only shape concern was higher for REOP group, F1,216 = 8.30, P<.001). CONCLUSIONS: Despite the preoperative similarities between patients undergoing reoperative or primary surgeries, the differences in binge eating and weight-related variables may associate with postoperative difficulties. The link between binge eating, weight suppression, and weight gain found in other samples suggests that patients undergoing reoperative surgery may be at increased risk for poor weight outcomes.

PMID- 29567058 TI - Increased circulating magnesium concentrations after Roux-en-Y gastric bypass surgery in patients with type 2 diabetes. AB - BACKGROUND: Low circulating magnesium concentrations predict cardiovascular and all-cause mortality in patients with type 2 diabetes (T2D). Epidemiologic and clinical studies have indicated lower extra- and intracellular magnesium concentrations in patients with diabetes. OBJECTIVE: We aimed to describe alterations, if any, in circulating magnesium concentrations after laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) in patients with obesity and T2D. SETTING: Outpatient clinic of obesity and central hospital. METHODS: Retrospective analysis of 1-year outcome of plasma magnesium (p-Mg) and glucometabolic status in all consecutive patients who underwent primary LRYGBP and who completed the follow-up visits, including biochemical test panels 6 and 12 months after surgery. RESULTS: LRYGBP and complete follow-up visits were performed in 51 patients with T2D and 86 patients without T2D. All patients were given similar dietary advice and multivitamin and mineral supplementation after surgery. Before RYGB, the patients with T2D showed lower p-Mg compared with patients without T2D (.79 +/- .06 mM and .82 +/- .05 mM, respectively, P<.01). P Mg was inversely correlated to fasting blood glucose and glycosylated hemoglobin levels. After surgery, mean p-Mg increased by 5.2% in the group with T2D compared with 1.4% in the patients without T2D (P<.01), ending at an equal level of .83 mM. The alterations in p-Mg were inversely related to the changes in fasting glucose and glycosylated hemoglobin concentrations. CONCLUSION: The lowered p-Mg associated with impaired glucometabolic status in patients with T2D was increased after LRYGBP, reaching similar concentrations as in patients without T2D. PMID- 29567059 TI - Conversion of standard Roux-en-Y gastric bypass to distal bypass for weight loss failure and metabolic syndrome: 3-year follow-up and evolution of technique to reduce nutritional complications. AB - BACKGROUND: Standard proximal Roux-en-Y gastric bypass (RYGB) fails to achieve long-term weight maintenance and/or control of metabolic syndrome in up to 35% of patients. OBJECTIVES: To improve the performance of the standard proximal gastric bypass by increasing the biliopancreatic limb length at the expense of the common channel. SETTINGS: Academic-affiliated private practice. METHODS: A retrospective review of all patients who underwent conversion to distal RYGB from 2010 to 2016 was performed. RYGB was modified by dividing the Roux limb at the jejunojejunostomy and transposing it distally to create a shortened total alimentary limb length (TALL) of 250 to 300 cm in the initial 11 patients. Of these, 7 developed protein calorie malnutrition and diarrhea requiring a second procedure to lengthen the common channel an additional 100 to 150 cm (TALL 400 450 cm), leading to resolution of all symptoms. The subsequent 85 patients were converted to distal RYGB with TALL 400 to 450 in a single-stage operation. RESULTS: Ninety-six RYGB patients underwent conversion to distal RYGB. The mean body mass index and mean excess weight loss at the time of distalization was 40.6 kg/m2 and 33.6%. At 1, 2, and 3 years after distalization, the mean body mass index was reduced to 34.4, 33.1, and 32.2 kg/m2, respectively, and excess weight loss improved to 41.9%, 53.7%, and 65.7%, respectively. Diabetes resolved in 66.7%, hypertension resolved in 28.6%, hyperlipidemia resolved in 40%, and sleep apnea resolved in 50% at 1 year. The 30-day complication rate and reoperation rates were 6.3% and 5.2%; an additional 7.3% (7/96) required reoperation for limb lengthening. Hypoalbuminemia developed in 21% at 3 years, but no increase in iron deficiency was observed. Calcium metabolism was affected by the distalization procedure to a greater degree as 21% of patients had low corrected calcium levels, 77% were deficient in vitamin D, and parathyroid hormone levels were above normal in 64% at 3 years. CONCLUSION: Revision of proximal RYGB to distal RYGB results in substantial improvement in weight loss and resolution of co morbidities at 3 years. Diarrhea and protein calorie malnutrition were seen frequently in patients with TALL of 250 to 300 cm, whereas patients with TALL 400 to 450 cm demonstrated a lower incidence of nutritional issues, but the effect on calcium, parathyroid hormone, and the fat soluble vitamins A and D is still a major concern. PMID- 29567060 TI - Laparoscopic sleeve gastrectomy as a viable option for an ambulatory surgical procedure: our 52-month experience. AB - BACKGROUND: We present our experience with same-day discharge (without an overnight stay) after laparoscopic sleeve gastrectomy (SG) in 821 consecutive patients from 2011 to 2015. This is the largest series published to date of patients undergoing ambulatory surgery for such a procedure. OBJECTIVES: To review our outcomes from ambulatory SG over 52 months to determine if SG can be safely performed in the ambulatory setting. SETTING: Ambulatory surgery center. METHODS: Retrospective review of all consecutive patients undergoing ambulatory SG from January 2011 to April 2015. All patients were discharged home the same day after surgery without an overnight stay at the hospital. Incidence of complications and admission to the hospital after discharge was reviewed up to 30 days from surgery. RESULTS: From January 2011 to April 2015, 821 consecutive patients underwent SG. Nineteen 30-day complications occurred in the series, 17 of them requiring admission to the hospital. Of the 19 cases, gastric leaks accounted for 7, intr-aabdominal abscess for 4, and dehydration/nausea/vomiting for 4; 4 were due to other causes. Complication and readmission rates at 30 days were 2.3% and 2.1%, respectively. Follow-up at 30 days was 98.4%. CONCLUSION: With stringent patient selection and utilization of enhanced recovery pathways, our study indicates that SG may be suitable for the outpatient setting. Experience and comfort with bariatric surgery is essential on the part of the operating surgeon to ensure good outcomes. Our low overall readmission and complication rate portends to the feasibility of laparoscopic SG as a safe outpatient procedure. PMID- 29567061 TI - Influence of stem length on component flexion and posterior condylar offset in revision total knee arthroplasty. AB - BACKGROUND: Hyperextension of the femoral component and excessive slope of the tibial component may delay the cam-post engagement in semi-constrained revision total knee arthroplasty (TKA). Further, it may compromise the posterior condylar offset (PCO). No prior study has determined whether a short 50-mm stem, or longer stems (100mm and 150mm) lead to less hyperextension of the femoral component or excessive slope and its influence on the posterior condylar offset. METHODS: Flexion/extension of the femoral component with respect to the sagittal femoral anatomic axis of the distal diaphysis (SFAA) and the tibial slope were measured from rotationally controlled lateral X-rays of 126 consecutive patients with a one- or two-stage revision TKA. Stems of 50mm, 100mm and 150mm were analyzed. Further, reconstruction of the PCO with respect to stem length and component flexion was evaluated. RESULTS: The average flexion (+) or extension (-) of the femoral component in the sagittal distal anatomical axis was -4.1 degrees +/-2.8 degrees (mean +/- std) for components, which have been implanted with 50-mm stems and 1.1 degrees +/-1.1 degrees for components with 100- or 150-mm stems, respectively (P=0.0001). The average slope of the tibial was 2.6 degrees +/-1.5 degrees for tibial trays with 50-mm stems, which was more than the 1.3 degrees +/-1 degrees for trays with 100-mm stems (P=0.0001). The average PCO ratio was 0.8+/-1.7 for femoral components with 50-mm stems, which was less than the 1.0+/ 1.7 for trays with 100-mm stems (P=0.0001). CONCLUSIONS: Because 50-mm stems resulted in about three degree hyperextension of the femoral component with respect to the SFAA compared to 100-mm or 150-mm stems, the longer stems do not alter the natural femoral flexion and a delay of the cam-post engagement may be avoided. Further, a better reconstruction of the PCO may be archived with the use of longer stems. PMID- 29567062 TI - Time to Talk: Can Radiologists Improve Follow-Up of Abdominal Imaging Findings Indeterminate for Malignancy by Initiating Verbal Communication? AB - PURPOSE: The aims of this study were to examine the association between radiologist-initiated verbal communication for abdominal imaging findings indeterminate for malignancy and receipt of relevant outpatient follow-up imaging and to evaluate the proportion of findings that progress from indeterminate to suspicious for malignancy. METHODS: Using a mandatory standardized assessment coding system, 727 eligible outpatient abdominal CT, MRI, and ultrasound studies performed between July 1, 2013, and January 31, 2014, were identified. Multivariate logistic regression was used to evaluate the association between radiologist-initiated verbal communication and receipt of relevant outpatient imaging follow-up, adjusted for patient, ordering physician, interpreting radiologist, and imaging variables. RESULTS: Sixty-two percent of patients (451 of 727) with imaging findings indeterminate for malignancy received relevant outpatient imaging follow-up. Radiologist-initiated verbal communication occurred in 4.8% of cases (35 of 727). Radiologist-initiated verbal communication (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.02-5.87) and existing cancer diagnosis (OR, 3.00; 95% CI, 2.11-4.26) were associated with a higher likelihood of receiving relevant imaging follow-up. Compared with those whose imaging studies were ordered by clinicians in a medical specialty, patients with studies ordered by clinicians in surgical (OR, 0.70; 95% CI, 0.49-0.99) or other (OR, 0.44; 95% CI, 20.24-0.83) specialties were less likely to receive relevant imaging follow-up. Progression of findings from indeterminate to suspicious for malignancy occurred in 5.4% of cases and was not associated with radiologist initiated verbal communication. CONCLUSIONS: Radiologist-initiated verbal communication increases the likelihood that patients receive outpatient imaging follow-up for abdominal findings indeterminate for malignancy. Progression of these findings is relatively infrequent. PMID- 29567063 TI - Robust qualitative estimation of time-varying contact rates in uncertain epidemics. AB - We will inevitably face new epidemics where the lack of long time-series data and the uncertainty about the outbreak dynamics make difficult to obtain quantitative predictions. Here we present an algorithm to qualitatively infer time-varying contact rates from short time-series data, letting us predict the start, relative magnitude and decline of epidemic outbreaks. Using real time-series data of measles, dengue, and the current zika outbreak, we demonstrate our algorithm can outperform existing algorithms based on estimating reproductive numbers. PMID- 29567064 TI - The distribution of district-level leprosy incidence in India is geometric stable, consistent with subcriticality. AB - Mathematical models predict that the community-level incidence of a controlled infectious disease across a region approaches a geometric distribution. This could hold over larger regions, if new cases remain proportional to existing cases. Leprosy has been disappearing for centuries, making an excellent candidate for testing this hypothesis. Here, we show the annual new case detection rate of leprosy in Indian districts to be consistent with a geometric distribution. For 2008-2013, goodness-of-fit testing was unable to exclude the geometric, and the shape parameter of the best fit negative binomial distribution was close to unity (0.95, 95% CI 0.87-1.03). Ramifications include that a district-level cross sectional survey may reveal whether an infectious disease is headed towards elimination, that apparent outliers are expected and not necessarily representative of program failure, and that proportion 1/e of a small geographical unit may not meet a control threshold even when a larger area has. PMID- 29567065 TI - PINK1/Parkin-mediated mitophagy was activated against 1,4-Benzoquinone-induced apoptosis in HL-60 cells. AB - Hematotoxicity of benzene is derived mainly from its active metabolite, 1,4 Benzoquinone (1,4-BQ), which induces cell apoptosis and mitochondrial damage. Damaged mitochondria are degraded through a specialized autophagy pathway, called mitophagy, which is driven by PINK1/Parkin signaling. However, whether mitophagy is involved in 1,4-BQ-induced toxicity remains unclear. This study was designed to investigate whether PINK1/Parkin-mediated mitophagy is activated in 1,4-BQ treated HL-60 cells, and the roles mitophagy plays in 1,4-BQ-induced apoptosis. Our results demonstrated that 1,4-BQ induced autophagy in HL-60 cells, characterized by increased LC3-II/LC3-I ratio and Beclin1 expression, as well as decreased expression of p62. We confirmed the presence of mitophagosomes using electron microscopy, and found that 1,4-BQ-induced autophagy was blocked by pretreatment with the mitophagy inhibitor Cyclosporine A (CsA). In addition, we found that 1,4-BQ induced mitochondrial stress through decreased mitochondrial membrane potential (MMP) and increasedproduction of reactive oxygen species (ROS). We also confirmed that 1,4-BQ-induced mitophagy was mediated by the PINK1/Parkin pathway, illustrated by increased expression of PINK1 and Parkin mRNA and protein. Finally, we examined 1,4-BQ-induced apoptosis with or without CsA, which demonstrated that apoptosis increased after mitophagy inhibition, suggesting that mitophagy has a protective effect in this context. In conclusion, this study demonstrates that the activated PINK1/Parkin-mediated mitophagy exerts a significantly protective effect against 1,4-BQ-induced apoptosis in HL-60 cells.

PMID- 29567068 TI - Dynamics of the human gut phageome during antibiotic treatment. AB - Bacterial viruses contribute to the dynamics of the microbiome communities, as they are involved in the horizontal gene transfer. Previously we studied changes in the gut microbiome of the two healthy individuals over the course of a 6-days antibiotics treatment and subsequent 28 days recovery time (Willmann et al., 2015). Now, from the same samples, the virus-like particles were isolated and sequenced. As the phage sequences are currently poorly represented in reference databases, the reads had to be assembled, annotated and their abundance had to be evaluated via reads mapping. We analyzed and compared patterns of changes in abundance of the phage scaffolds and scaffolds with antibiotics resistant genes, in both phage and whole-genome metagenomic sets. We observed an increase in abundance of scaffolds carrying antibiotic-resistant genes in response to the treatment. PMID- 29567069 TI - The short-term presence of oleate or octanoate alters the phosphorylation status of Akt, AMPK, mTOR, CREB, and FoxO1 in liver of rainbow trout (Oncorhynchus mykiss). AB - We hypothesized that the presence of specific fatty acids modulate lipid metabolism in fish liver through changes in the phosphorylation status of proteins involved in cell signaling (Akt and mTOR) and cellular energy sensing (AMPK), and transcription factors (CREB and FoxO1). Therefore, we evaluated in pools of rainbow trout livers incubated for 3 h and 6 h at 15 degrees C in modified Hanks' medium containing 100 or 500 MUM oleate or octanoate, the response of these proteins. Our data confirm, for the first time in fish, that treatment of rainbow trout liver with oleate or octanoate resulted in the modulation of phosphorylation status of proteins involved in cell signaling (increased Akt and mTOR) and energy sensing (decreased AMPK), and in transcription factors (decreased CREB and increased FoxO1). The changes in these proteins occurred at the same time that changes in the mRNA abundance of several genes involved in lipid metabolism suggesting enhanced lipogenic potential (increased mRNA abundance of FAS, SREBP1c, and PPARalpha) and decreased mitochondrial activity (decreased UCP2a mRNA abundance) allowing us to suggest a relationship between both processes. PMID- 29567070 TI - Identification of duplicated Midkine genes and their functional regulation in blunt snout bream (Megalobrama amblycephala). AB - Midkine (Mdk) is a heparin-binding growth factor that is involved in regulating cell growth, differentiation and migration. Here, we report the isolation and characterization of duplicated mdk genes in blunt snout bream (Megalobrama amblycephala). The mdka and -b genes encode 146 aa and 147 aa peptides, respectively, sharing a sequence identity of 64%. During embryogenesis, mdka mRNA is detectable after 12 h post-fertilization (hpf) and mdkb mRNA can be detected after 8 hpf, about 4 h prior to mdka mRNA. Whole-mount in situ hybridization demonstrated that two paralogs of mdk mRNA were detected in the brain and dorsal neural tube at 16 hpf. At 22 hpf, mdka mRNA was abundant in the brain and dorsal neural tube, whereas mdkb mRNA were transcribed in the brain and tailbud. Later, at 55 hpf, both paralogs were mainly expressed in the brain. Furthermore, both the mdk genes were highly expressed in multiple adult tissues except in the skin and a low expression of mdka in the muscle. In addition, they were differentially inhibited in the liver and intestine with exogenous recombinant human growth hormone, while their mRNA levels were up-regulated in the brain. During starvation, both the mdk genes were significantly up-regulated in the intestine, brain and liver and returned to the control levels following 6 days of refeeding. Our results suggest that duplicated mdk genes may play conserved and divergent roles in embryonic development and tissue growth regulation in blunt snout bream. PMID- 29567071 TI - Predictive test for chemotherapy response in resectable gastric cancer: a multi cohort, retrospective analysis. AB - BACKGROUND: Adjuvant chemotherapy after surgery improves survival of patients with stage II-III, resectable gastric cancer. However, the overall survival benefit observed after adjuvant chemotherapy is moderate, suggesting that not all patients with resectable gastric cancer treated with adjuvant chemotherapy benefit from it. We aimed to develop and validate a predictive test for adjuvant chemotherapy response in patients with resectable, stage II-III gastric cancer. METHODS: In this multi-cohort, retrospective study, we developed through a multi step strategy a predictive test consisting of two rule-based classifier algorithms with predictive value for adjuvant chemotherapy response and prognosis. Exploratory bioinformatics analyses identified biologically relevant candidate genes in gastric cancer transcriptome datasets. In the discovery analysis, a four-gene, real-time RT-PCR assay was developed and analytically validated in formalin-fixed, paraffin-embedded (FFPE) tumour tissues from an internal cohort of 307 patients with stage II-III gastric cancer treated at the Yonsei Cancer Center with D2 gastrectomy plus adjuvant fluorouracil-based chemotherapy (n=193) or surgery alone (n=114). The same internal cohort was used to evaluate the prognostic and chemotherapy response predictive value of the single patient classifier genes using associations with 5-year overall survival. The results were validated with a subset (n=625) of FFPE tumour samples from an independent cohort of patients treated in the CLASSIC trial (NCT00411229), who received D2 gastrectomy plus capecitabine and oxaliplatin chemotherapy (n=323) or surgery alone (n=302). The primary endpoint was 5-year overall survival. FINDINGS: We identified four classifier genes related to relevant gastric cancer features (GZMB, WARS, SFRP4, and CDX1) that formed the single patient classifier assay. In the validation cohort, the prognostic single patient classifier (based on the expression of GZMB, WARS, and SFRP4) identified 79 (13%) of 625 patients as low risk, 296 (47%) as intermediate risk, and 250 (40%) as high risk, and 5 year overall survival for these groups was 83.2% (95% CI 75.2-92.0), 74.8% (69.9 80.1), and 66.0% (60.1-72.4), respectively (p=0.012). The predictive single patient classifier (based on the expression of GZMB, WARS, and CDX1) assigned 281 (45%) of 625 patients in the validation cohort to the chemotherapy-benefit group and 344 (55%) to the no-benefit group. In the predicted chemotherapy-benefit group, 5-year overall survival was significantly improved in those patients who had received adjuvant chemotherapy after surgery compared with those who received surgery only (80% [95% CI 73.5-87.1] vs 64.5% [56.8-73.3]; univariate hazard ratio 0.47 [95% CI 0.30-0.75], p=0.0015), whereas no such improvement in 5-year overall survival was observed in the no-benefit group (72.9% [66.5-79.9] in patients who received chemotherapy plus surgery vs 72.5% [65.8-79.9] in patients who only had surgery; 0.93 [0.62-1.38], p=0.71). The predictive single patient classifier groups (chemotherapy benefit vs no-benefit) could predict adjuvant chemotherapy benefit in terms of 5-year overall survival in the validation cohort (pinteraction=0.036 in univariate analysis). Similar results were obtained in the internal evaluation cohort. INTERPRETATION: The single patient classifiers validated in this study provide clinically important prognostic information independent of standard risk-stratification methods and predicted chemotherapy response after surgery in two independent cohorts of patients with resectable, stage II-III gastric cancer. The single patient classifiers could complement TNM staging to optimise decision making in patients with resectable gastric cancer who are eligible for adjuvant chemotherapy after surgery. Further validation of these results in prospective studies is warranted. FUNDING: Ministry of ICT and Future Planning; Ministry of Trade, Industry, and Energy; and Ministry of Health and Welfare.

PMID- 29567074 TI - Effect of diabetes duration and glycaemic control on 14-year cause-specific mortality in Mexican adults: a blood-based prospective cohort study. AB - BACKGROUND: Diabetes is a cause of at least a third of all deaths in Mexican adults aged 35-74 years, with the excess mortality due mainly to vascular disease, renal disease, infection, and acute diabetic crises. We aimed to analyse the effect of diabetes duration and glycaemic control on death rate ratios (RRs) for these causes and to assess the relevance to cause-specific mortality of undiagnosed diabetes. METHODS: About 100 000 women and 50 000 men aged 35 years or older from Mexico City were recruited into a blood-based prospective study between April 14, 1998, and Sept 28, 2004, and followed up until Jan 1, 2016, for cause-specific mortality. Participants who, at recruitment, reported any chronic disease other than diabetes and those who had missing data for HbA1c or diabetes duration were excluded. We used Cox models to estimate the associations of undiagnosed or previously diagnosed diabetes (almost all type 2) with risk of mortality from vascular disease, renal disease, and infection, exploring among those with previously diagnosed diabetes the independent relevance of diabetes duration (<5 years, >=5 to <10 years, or >=10 years) and HbA1c (<9%, >=9% to <11%, or >=11%). We also estimated the association of HbA1c with mortality in participants without diabetes at recruitment. FINDINGS: 133 662 participants were aged 35-74 years and had complete data and no other chronic disease. 16 940 (13%) had previously diagnosed diabetes, 6541 (5%) had undiagnosed diabetes, and 110 181 (82%) had no diabetes. Among participants with previously diagnosed diabetes, glycaemic control was poor (median HbA1c 8.9% [IQR 7.0-10.9]), and was worse in those with longer duration of disease at recruitment. Compared with participants without diabetes, the death RRs at ages 35-74 years for the combination of vascular, renal, or infectious causes were 3.0 (95% CI 2.7-3.4) in those with undiagnosed diabetes, 4.5 (4.0-5.0) for the 5042 participants with a diabetes duration of less than 5 years, 6.6 (6.1-7.1) for the 7713 participants with a duration of 5 years to less than 10 years, and 11.7 (10.7-12.7) for the 4185 participants with a duration of at least 10 years. Similarly, the death RRs were 5.2 (4.8-5.7) for those with HbA1c less than 9%, 6.8 (6.2-7.4) for those with HbA1c of 9% to less than 11%, and 10.5 (9.7-11.5) for those with HbA1c of at least 11%. Diabetes was not strongly associated with the combination of deaths from other causes apart from acute glycaemic crises. Among participants without diabetes, higher HbA1c was not positively related to mortality. INTERPRETATION: In Mexico, the rates of death from causes strongly associated with diabetes increased steeply with duration of diabetes and were higher still among people with poor glycaemic control. Delaying the onset of type 2 diabetes, as well as improving its treatment, is essential to reduce premature adult mortality in Mexico.

PMID- 29567075 TI - Astragaloside IV inhibits Angiotensin II-stimulated proliferation of rat vascular smooth muscle cells via the regulation of CDK2 activity. AB - AIMS: Astragaloside IV (AS-IV) is the central active component extracted from Radix astragali, an herbal remedy widely used in traditional Chinese medicine for the treatment of cardiovascular diseases. Aberrant proliferation of vascular smooth muscle cells (VSMCs) is closely involved in the initiation and progression of cardiovascular complications, such as atherosclerosis. Here we investigated whether AS-IV inhibited agonist-induced vascular smooth muscle cells (VSMCs) proliferation and the underlying mechanism. MAIN METHODS: Quiescent cultured A10 cells (adult rat VSMCs) were treated with Angiotensin II (AngII) or AngII plus AS IV for 48 h. The growth rate of A10 cells was analyzed by CCK8 assay. RT-PCR analysis was carried out to examine the expression of alpha-smooth muscle actin (alpha-SMA), an important phenotypic modulation marker. In addition, whether the interference of AS-IV on AngII-mediated growth of VSMCs via regulation of cell cycle was evaluated by flow cytometry. In order to explore the role of cell cycle machinery, we measured kinase activity of CDK2 by Kinase assay and the protein level of Cdc25 by western blot, respectively. KEY FINDINGS: These data suggested that AS-IV exerted beneficial effects on AngII -induced abnormal growth in rat VSMCs through disturbing cell cycle, especially block G1/S transition by attenuating CDK2 activity, which may hinder the process of pathological vascular remodeling during atherosclerosis. PMID- 29567076 TI - Involvement of the nitric oxide in melatonin-mediated protection against injury. AB - Melatonin is a hormone mainly synthesized by the pineal gland in vertebrates and known well as an endogenous regulator of circadian and seasonal rhythms. It has been demonstrated that melatonin is involved in many physiological and pathophysiological processes showing antioxidant, anti-apoptotic and anti inflammatory properties. Nitric oxide (NO) is a free radical gas in the biological system, which is produced by nitric oxide synthase (NOS) family. NO acts as a biological mediator and plays important roles in different systems in humans. The NO/NOS system exerts a broad spectrum of signaling functions. Accumulating evidence has clearly revealed that melatonin regulates NO/NOS system through multiple mechanisms that may influence physiological and pathophysiological processes. This article reviews the latest evidence for the effects of melatonin on NO/NOS regulation in different organs and disease conditions, the potential cellular mechanisms by which melatonin is involved in organ protection are discussed. PMID- 29567077 TI - Idiopathic pulmonary fibrosis (IPF) signaling pathways and protective roles of melatonin. AB - Idiopathic pulmonary fibrosis (IPF) is characterized by the progressive loss of lung function due to tissue scarring. A variety of pro-inflammatory and pro fibrogenic factors including interleukin-17A, transforming growth factor beta, Wnt/beta-catenin, vascular endothelial growth factor, platelet-derived growth factor, fibroblast growth factors, endotelin-1, renin angiotensin system and impaired caveolin-1 function are involved in the IPF pathogenesis. Current therapies for IPF have some limitations and this highlights the need for effective therapeutic agents to treat this fatal disease. Melatonin and its metabolites are broad-spectrum antioxidants that not only remove reactive oxygen and nitrogen species by radical scavenging but also up-regulate the expression and activity of endogenous antioxidants. Via these actions, melatonin and its metabolites modulate a variety of molecular pathways in different pathophysiological conditions. Herein, we review the signaling pathways involved in the pathophysiology of IPF and the potentially protective effects of melatonin on these pathways. PMID- 29567078 TI - Beneficial role of biochanin A on cutaneous and renal tissues of ovariectomized rats treated with anastrozole. AB - AIMS: This study was designed to assess the beneficial role of biochanin A (BCA) in the protection of the cutaneous and renal tissues of ovariectomized rats, even in those treated with anastrozole (ANA). MATERIALS AND METHODS: For this purpose, 60 adult female Wistar rats were allocated into 6 equal groups. Rats in group I (sham) underwent a sham operation and received distilled water orally. In groups II and III, OVX rats received either distilled water orally or DMSO intraperitoneally, respectively. In groups IV and V, OVX rats were either treated orally with 0.5 mg ANA/kg.b.wt. or administered 5 mg of BCA/kg.b.wt. intraperitoneally, respectively. In group VI (OVX-ANA-BCA), OVX rats were co treated with BCA and ANA. All treatments were given daily for 20 weeks. KEY FINDINGS: The IP administration of BCA significantly decreased serum levels of urea, creatinine, uric acid and MDA and significantly increased serum CAT, GSH and TAC and cutaneous IL-4 and GATA3 concentrations in the fifth and sixth groups compared to OVX-DMSO and OVX-ANA groups, respectively. Additionally, it induced down-regulation of renal TNF-alpha and iNOS expression as well as up-regulation of cutaneous TGF-beta expression. Furthermore, BCA ameliorated to variable degrees histological changes of renal and cutaneous tissue related to ovariectomy and/or ANA treatment. SIGNIFICANCE: These data suggest that BCA might be a useful alternative estrogen therapy for the management of renal and cutaneous changes observed in postmenopausal women, even in those treated with ANA. PMID- 29567080 TI - The Effect of Omega-3 on Circulating Adiponectin in Adults With Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. AB - Whether consumption of omega-3 affects circulating adiponectin has not been established. The objective of this study was to evaluate the effect of omega-3 (food or supplement) on circulating adiponectin in patients with type 2 diabetes through a systematic review of meta-analyses of randomized controlled trials. PubMed, Scopus and Web of Science were searched for relevant studies through May 2016. Two researchers screened and abstracted the literature independently. Pooled estimates were obtained using the random-effects models. Overall, omega-3 increased adiponectin by 0.57 ug/mL (95% confidence interval [CI] 0.15 to 1.31; p=0.01, I-square=74.2% p for heterogeneity <0.001). The source of observed heterogeneity was explored by subgroup analyses. In subgroup analyses, adiponectin levels increased only in those who had consumed omega-3 for more than 8 weeks. This systematic review and meta-analysis of randomized, placebo controlled clinical trials suggests that omega-3 in patients with type 2 diabetes increases circulating adiponectin. These findings support the potentially beneficial effects of dietary omega-3 in patients with type 2 diabetes on pathways related to adiponectin metabolism. PMID- 29567079 TI - Early-Onset Physical Frailty in Adults With Diabesity and Peripheral Neuropathy. AB - OBJECTIVES: Diabesity (obesity and diabetes mellitus) has been identified as a potential contributor to early-onset frailty. Impairments contributing to early onset of physical frailty in this population are not well understood, and there is little evidence of the impact of peripheral neuropathy on frailty. The purpose of this study was to determine impairments that contribute to early-onset physical frailty in individuals with diabesity and peripheral neuropathy. METHODS: We studied 105 participants, 82 with diabesity and peripheral neuropathy (57 years of age, body mass index [BMI] 31 kg/m2); 13 with diabesity only (53 years of age, BMI 34 kg/m2) and 10 obese controls (67 years of age, BMI 32 kg/m2). Peripheral neuropathy was determined using Semmes Weinstein monofilaments; physical frailty was classified using the 9-item, modified Physical Performance Test; and knee extension and ankle plantarflexion peak torques were measured using isokinetic dynamometry. RESULTS: Participants with diabesity and peripheral neuropathy were 7.4 times more likely to be classified as physically frail. Impairments in lower-extremity function were associated with classification of frailty. CONCLUSIONS: Individuals with diabesity and peripheral neuropathy are particularly likely to be classified as frail. Earlier identification and interventions aimed at improving lower-extremity function may be important to mitigate the early-onset functional decline.

PMID- 29567081 TI - Activity of Mesothelin-Specific Chimeric Antigen Receptor T Cells Against Pancreatic Carcinoma Metastases in a Phase 1 Trial. AB - Pancreatic ductal adenocarcinoma (PDAC) is resistant to T-cell-mediated immunotherapy. We engineered T cells to transiently express a messenger RNA encoding a chimeric antigen receptor (CAR) specific for mesothelin, a protein that is overexpressed by PDAC cells. We performed a phase I study to evaluate the safety and efficacy of adoptive cell therapy with autologous mesothelin-specific CAR T cells (CARTmeso cells) in 6 patients with chemotherapy-refractory metastatic PDAC. Patients were given intravenous CARTmeso cells 3 times weekly for 3 weeks. None of the patients developed cytokine release syndrome or neurologic symptoms and there were no dose-limiting toxicities. Disease stabilized in 2 patients, with progression-free survival times of 3.8 and 5.4 months. We used 18F-2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography/computed tomography imaging to monitor the metabolic active volume (MAV) of individual tumor lesions. The total MAV remained stable in 3 patients and decreased by 69.2% in 1 patient with biopsy-proven mesothelin expression; in this patient, all liver lesions had a complete reduction in FDG uptake at 1 month compared with baseline, although there was no effect on the primary PDAC. Transient CAR expression was detected in patients' blood after infusion and led to expansion of new immunoglobulin G proteins. Our results provide evidence for the potential antitumor activity of messenger RNA CARTmeso cells, as well as PDAC resistance to the immune response. PMID- 29567083 TI - Bilateral simultaneous endoscopic carpal tunnel release: Mean time to resume activities of daily living and return to work. AB - : The purpose of this study was to determine the time needed to return to personal and professional activities after bilateral simultaneous endoscopic carpal tunnel release. During a retrospective, single-center study, we included a cohort of 30 patients (60 wrists). Patients were evaluated clinically (pain, paresthesia) and functionally (QuickDASH score) pre- and postoperatively. At the last follow-up, patients completed a questionnaire regarding the time needed to resume personal activities using the ADL scale (feeding, personal hygiene and dressing) and return to work. We also evaluated procedure satisfaction and willingness to undergo the surgery again. The average patient age was 60.5 years (range 39-86). At the last follow-up, average time to resume personal activities was 2.2 days (0-14) for feeding, 4.4 days (0-15) for personal hygiene and 3.9 days (0-14) for dressing. Average time to return to recreational activities was 11.7 days (1-60). Average time to return to work was 36.6 days (15-60). Overall, 97% of patients were satisfied or very satisfied with the outcome. All patients would have the bilateral simultaneous surgery again. Bilateral simultaneous endoscopic carpal tunnel release is rarely performed. For mild conditions, contralateral symptom improvement is common after unilateral surgery. Bilateral simultaneous endoscopic carpal tunnel release appears to be disabling right after surgery, but clinical and functional scores are similar after the third postoperative day. These data can be used for patient education and decision making when considering surgery bilateral carpal tunnel syndrome. Bilateral simultaneous endoscopic carpal tunnel release is a feasible and safe procedure. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29567084 TI - Aneurysms of the hand: Imaging and surgical technique. AB - Hand aneurysms are a rare entity only described as case reports in the literature. The aim of our study was to describe a series of four cases and the surgical technique using an arterial bypass. We also wanted to define an algorithm for the imaging of this pathology. We have operated on four patients with hand aneurysms in the past decade or so. One patient had an aneurysm in the thumb proper palmar digital artery, one in the superficial palmar arch and the two others in the ulnar artery. All patients had an excision surgery with direct arterial bypass; no patient had a venous graft. All patients were seen a few years after the surgery and underwent an ultrasonography to check the anastomosis permeability. All anastomoses were permeable 2 to 8 years after surgery. Through a review of the literature we discuss the best algorithm for imaging a hand aneurysm. Direct arterial suture by proximal and distal mobilization allows for long-term permeability. If a graft is necessary, a graft of arterial origin should be preferred. The additional first-line examination is ultrasonography, followed by arteriography if acute ischemia is present; otherwise, CT angiography or MR angiography is performed. PMID- 29567085 TI - Fixation of the nail plate by tension band suture versus 2-octyl-cyanoacrylate gluing for traumatic nail bed injuries reduced without suture: A retrospective study of 27 cases. AB - Repair of the nail bed and plate after distal phalanx trauma remains controversial. The aim of this study was to determine whether simple approximation of the nail bed flaps maintained by tension band suture of the nail plate is sufficient to prevent nail dystrophies. Our series gathered 27 fingers in 25 patients with a mean age of 36 years. In 15 cases (Group I), the nail plate was fixed in a single layer by a point in a frame, and in 12 cases (Group II), the bed and the plate were fixed layer-by-layer using the wound adhesive, 2 octylcyanoacrylate. At the last follow-up, the Zook score was excellent and very good in 100% of Group I patients, and in 83.3% of Group II patients. Within 8 days, the average pain was 1/10 in Group I, and 2.5/10 in Group II. There was one infection in Group I and four hematomas in Group II. The Quick DASH score was 1.13/100 in Group I and 0 in Group II. Our results show that in the case of a traumatic nail bed injury, suturing the nail bed and applying 2 octylcyanoacrylate adhesive is less effective than simple approximation of the nail bed flaps by tension band suture of the nail plate. PMID- 29567086 TI - Ultrasonographic evaluation of the distance between the flexor pollicis longus tendon and volar prominence of the plate as a function of volar plate positioning and pronator quadratus repair - A cadaver study. AB - Flexor tendon injury after volar plating of distal radius fractures is due to friction against the plate. To assess this risk, the distance between the flexor pollicis longus (FPL) and the volar prominence of the plate was measured with ultrasonography under various conditions: a standard plate fixed proximal or distal to the watershed line and a low-profile volar rim plate, with and without transection of the pronator quadratus (PQ). Distance from the FPL to the volar prominence of the plate decreased significantly when the PQ was cut and when a standard plate was placed distal to the watershed line, with the tendon often bulging over the plate. No statistical difference was measured between a volar rim plate and a standard plate distal to the watershed line. Our results confirm the importance of positioning the volar plate proximal to the watershed line and of repairing the PQ. PMID- 29567087 TI - A theoretical framework for the interpretation of pharmacist workforce studies throughout the world: The labor supply curve. AB - Despite geographic, financial, and cultural diversity, publications dealing with the pharmacist workforce throughout the world share common concerns and focus on similar topics. Their findings are presented in the literature in a seemingly unrelated way even though they are connected to one another as parts of a comprehensive theoretical structure. The purpose of this paper is to develop a theoretical model that relates some of the most salient topics addressed in the international literature on pharmacist workforce. The model is developed along two fundamental ideas. The first identifies the shape and location of the pharmacist's labor supply curve as the driving force behind all workforce decisions undertaken by pharmacists; the second argues that gender and age differences are two of the most important factors determining the shape and location of this supply curve. The paper then discusses movements along the curve attributed to changes in the wage rate, as well as displacements of the curve attributed to disparities in personal characteristics, investments in human capital, job-related preferences, opinions and perceptions, and institutional rigidities. The focus is on the individual pharmacist, not on groups of pharmacists or the profession as a whole. Works in multiple countries that address each topic are identified. Understanding these considerations is critical as employers' failure to accommodate pharmacists' preferences for work and leisure are associated with negative consequences not only for them but also for the healthcare system as a whole. Possible consequences include excessive job turnover, absenteeism, decreased institutional commitment, and lower quality of work. PMID- 29567088 TI - Community pharmacists' understanding and perceptions of FDA therapeutic equivalence standards. AB - BACKGROUND: Pharmacists need to demonstrate knowledge of and have confidence in Food and Drug Administration (FDA) therapeutic equivalence (TE) standards to improve acceptance of generic medicines amongst patients and other healthcare professionals. OBJECTIVE: To evaluate community pharmacists' understanding, interpretation and perceptions of the FDA TE standards to identify if further education is needed on this topic. METHODS: An anonymous, 13-item survey was piloted and then distributed by e-mail to a random sample of 287 Indiana community pharmacists. The 5-min survey included demographic, knowledge-based, and perception-based questions on FDA TE criteria that participants were given one week to complete. Participants completed the survey using a Web-based survey tool (Qualtrics). RESULTS: 192 pharmacists completed the survey achieving a response rate of 66.9%. Only 7.3% of respondents correctly identified FDA bioequivalence criteria for approval of generic drug products. Two questions presented TE codes from the Orange Book and asked respondents to identify if a pair of drug products were therapeutically equivalent: 62.6% and 61.0% of respondents answered correctly. However, 89.4% of respondents correctly indicated that the Orange Book is the location of FDA TE evaluations. 74.9% of responding pharmacists indicated a positive perception of the rigor of FDA approval standards associated with generic medications and 66.0% believed that generic drug products made by different manufacturers are of similar quality. CONCLUSIONS: The results suggest that community pharmacists need additional education on the interpretation of TE codes and FDA bioequivalence criteria for approval of generic drug products. The safety and efficacy of generics are often questioned by patients and physicians. It is important for pharmacists to be knowledgeable of FDA TE standards as they are experts in medicines and need to be confident with the criteria to effectively convey them to patients and healthcare professionals. PMID- 29567089 TI - An overview of the toxicities of checkpoint inhibitors in older patients with cancer. AB - Checkpoint inhibitors offer an exciting new option for treatment of a wide variety of cancers. By binding to surface receptors or their associated ligands on T cells, this class of drugs enhances immune activation and response to cancer cells. In available studies, the drugs are well tolerated, although toxicity involving skin, gastrointestinal tract, liver, lungs, and endocrine organs has been observed. Unfortunately, few studies to date have included patients older than 70 years of age. Since aging has been linked to changes in immune function, there are theoretical concerns that this patient population might experience a different profile of adverse events. This article reviews the tolerability of checkpoint inhibitors in older patients with cancer in clinical practice. PMID- 29567091 TI - Non-contrast MDCT for Ureteral Calculi and Alternative Diagnoses: Yield in Adult Women vs in Adult Men. AB - PURPOSE: To determine the yield of non-contrast multi-detector computed tomography (MDCT) of the abdomen and pelvis in diagnosing ureteral calculi as well as other alternative acute conditions in male vs in female adult patients presenting to the emergency department with new onset of symptoms. METHODS: Our institutional review board approved a retrospective review of the official reports of the non-contrast MDCT examinations of the abdomen and pelvis performed on adults (18 years and older) presenting to our emergency department with a suspected ureteral calculus from October 1, 2011 to October 30, 2013. Patients with recently documented ureteral calculi, known urinary tract infection, malignancy, and trauma were excluded from the study. From a total of 1097 non contrast MDCT examinations of the abdomen and pelvis over the 2-year period, 400 randomly selected examinations were reviewed (approximately one-third of all the examinations). We compared the prevalence of ureteral calculi between the male and female population. P values and confidence intervals were determined using software Stata 14. Other acute intra-abdominal and intra-pelvic findings amenable to prompt medical care were also documented and analyzed separately. RESULTS: The mean patient age was 55.2 years, with a range of 19-90 years. This included 170 female (mean age 56.8 years) and 230 male patients (mean age 54.2 years). Ureteral calculi were detected in 170 (42.5%) of the patients [111 males (48%) and 59 females (34.7%)] with a prevalence which was statistically significantly higher in the male patients compared to in the female patients (P < 0.01, confidence level of 95% and CI of 13.2-13.4). An alternative diagnosis was made based on the MDCT findings in 49 patient cases (12.25 %), including 26 females (15.29%) and 23 males (10.00%). There was no statistically significant difference in alternative acute findings in male compared to in female patients (P > 0.05). This was with the exception of acute pyelonephritis, which was statistically significantly higher in the female patients (P < 0.01). CONCLUSION: The likelihood of making the diagnosis of a ureteral calculus on non-contrast MDCT of the abdomen and pelvis was statistically significantly higher in male patients compared with female patients presenting to our emergency department. However, there was no statistically significant difference in the alternative diagnoses, with the exception of pyelonephritis, which was more common in women. PMID- 29567090 TI - Quantitation of myosin regulatory light chain phosphorylation in biological samples with multiple reaction monitoring mass spectrometry. AB - The 20-kDa regulatory light chain of myosin II plays an important role in regulating smooth muscle contractile force. LC20 is phosphorylated canonically by myosin light chain kinase in a Ca2+/calmodulin-dependent manner at S19. The diphosphorylation of LC20 at T18 and S19 has been observed in smooth muscle tissues. Given that the phosphorylation of LC20 is positively correlated with tension development, the molar stoichiometry of LC20 phosphorylation is commonly profiled as a measure of smooth muscle contractility. Herein, we describe a novel multiple reaction monitoring (MRM)-mass spectrometry (MS) approach for the quantification of LC20 phosphorylation at T18 and S19. Unique precursor as well as y- and b-ion transitions were identified for unphosphorylated LC20-(TS), monophosphorylated LC20-(TpS) and diphosphorylated LC20-(pTpS) peptides. The MRM MS assay could accurately define molar phosphorylation stoichiometries of S19 and T18 over a broad range (i.e., 0-2 mol P/mol LC20). Correlations of the results for two quantification techniques indicate that the MRM-MS assay performs equally to Phos-tag SDS-PAGE for the determination of LC20 phosphorylation stoichiometry in arterial tissue samples. The MRM-MS technique provides a robust alternative to antibody-based detection systems for the quantification of LC20 phosphorylation. PMID- 29567092 TI - Nucleus accumbens GLT-1a overexpression reduces glutamate efflux during reinstatement of cocaine-seeking but is not sufficient to attenuate reinstatement. AB - Cocaine use disorder is a chronically relapsing disease without FDA-approved treatments. Using a rodent model of cocaine relapse, we and others have previously demonstrated that the beta-lactam antibiotic ceftriaxone attenuates cue- and cocaine-primed reinstatement of cocaine-seeking. Ceftriaxone restores cocaine-induced deficits in both system xc- and GLT-1 expression and function in the nucleus accumbens core (NAc). We recently demonstrated that restoration of GLT-1 expression in the NAc is necessary for ceftriaxone to attenuate reinstatement of cocaine-seeking. Here we used an adeno-associated virus (AAV) to overexpress GLT-1a in the NAc to investigate whether such restoration is sufficient to attenuate cue- and cocaine-primed reinstatement. Rats self administered cocaine for two weeks and received injections of either AAV-GFAP-GLT 1a or AAV-GFAP-eGFP in the NAc following the last day of self-administration. Rats then underwent three weeks of extinction training (during which time transduction and expression occurred) before undergoing a cue- or cocaine-primed reinstatement test. Microdialysis for the quantification of glutamate efflux in the NAc was conducted during the cocaine-primed test. Rats that received AAV-GFAP GLT-1a reinstated cue-primed cocaine-seeking in a similar manner as rats that received the control AAV-GFAP-eGFP. Upregulation of GLT-1a attenuated glutamate efflux during a cocaine-primed reinstatement test, but was not sufficient to attenuate reinstatement. We confirmed that GLT-1a upregulation resulted in functional upregulation of glutamate transport and expression, without affecting sodium-independent glutamate uptake, indicating system xc-was not altered. These results indicate that upregulation of NAc GLT-1 transporters alone is not sufficient to prevent the reinstatement of cocaine-seeking and implicate additional mechanisms in regulating glutamate efflux.

AB - Cigarette smokers with brain damage involving the insular cortex display cessation of tobacco smoking, suggesting that this region may contribute to nicotine addiction. In the present study, we speculated that molecules in the insular cortex that are sensitive to experimental traumatic brain injury (TBI) in mice might provide leads to ameliorate nicotine addiction. Using targeted lipidomics, we found that TBI elicited substantial increases of a largely uncharacterized lipid, N-acyl-glycine, N-oleoyl-glycine (OlGly), in the insular cortex of mice. We then evaluated whether intraperitoneal administration of OlGly would alter withdrawal responses in nicotine-dependent mice as well as the rewarding effects of nicotine, as assessed in the conditioned place preference paradigm (CPP). Systemic administration of OlGly reduced mecamylamine precipitated withdrawal responses in nicotine-dependent mice and prevented nicotine CPP. However, OlGly did not affect morphine CPP, demonstrating a degree of selectivity. Our respective in vitro and in vivo observations that OlGly activated peroxisome proliferator-activated receptor alpha (PPAR-alpha) and the PPAR-alpha antagonist GW6471 prevented the OlGly-induced reduction of nicotine CPP in mice suggests that this lipid acts as a functional PPAR-alpha agonist to attenuate nicotine reward. These findings raise the possibility that the long chain fatty acid amide OlGly may possess efficacy in treating nicotine addiction.

AB - Aquaculture is a rapidly growing industry that currently accounts for almost half of the fish used for human consumption worldwide. Intensive and semi-intensive practices are used to produce large stocks of fish, but frequent disease outbreaks occur, and the use of antimicrobials has become a customary practice to control them. The selective pressure exerted by these drugs, which are usually present at sub-therapeutic levels for prolonged periods in the water and the sediments, provides ideal conditions for the emergence and selection of resistant bacterial strains and stimulates horizontal gene transfer. It is now widely recognized that the passage of antimicrobial resistance genes and resistant bacteria from aquatic to terrestrial animal husbandry and to the human environment and vice versa can have detrimental effects on both human and animal health and on aquatic ecosystems. A global effort must be made to cease antimicrobial overuse in aquaculture and encourage stakeholders to adopt other disease-prevention measures. Shaping a new path is crucial to containing the increasing threat of antimicrobial resistance. PMID- 29567095 TI - Antioxidant-based synergistic eradication of methicillin-resistant Staphylococcus aureus (MRSA) biofilms with bacitracin. AB - Biofilms of methicillin-resistant Staphylococcus aureus (MRSA) have serious clinical implications. However, it is difficult to eradicate MRSA biofilms due to the increased tolerance to antimicrobials of biofilms. In this study, we investigated the synergistic anti-biofilm effect of the combination of octyl gallate (OG), an antioxidant approved by the US Food and Drug Administration (FDA) as a food additive, and bacitracin, an antimicrobial peptide commonly used in topical antimicrobial ointments. The results of biofilm assays showed that OG enabled bacitracin at concentrations as low as 10-3 U/ml to inhibit biofilm formation in MRSA. A confocal microscopic analysis exhibited that the combination of bacitracin and OG suppressed biofilm formation in MRSA highly effectively compared to the single treatment of either bacitracin or OG. The synergistic anti biofilm activity of bacitracin and OG was also confirmed in MRSA strains from humans, including USA300, which is the predominant clone of community-associated MRSA in the US. To the best of our knowledge, this is the first report about the synergistic anti-biofilm activity of an antimicrobial peptide and an antioxidant against MRSA.

PMID- 29567097 TI - Differential neural responses to faces paired with labels versus faces paired with noise at 6- and at 9-months. AB - Labeling objects or faces in the first year of life shapes subsequent attention and perception. Three months of hearing individual-level, unique labels for previously unfamiliar faces promotes face differentiation and impacts neural processing during the first year of life. However, it is currently unclear whether verbal labeling influences visual processing of faces during label learning and whether these effects differ across the first year of life. The current study examined the impact of individual-level labels versus a non-speech noise on neural responses to monkey faces. Event-related potentials (ERPs) were recorded while infants viewed two species of monkey faces: one paired with labels and one paired with a non-speech noise. At 9 months, neural responses differentiated monkey faces paired with labels relative to those paired with noise during both the first and second halves of the experiment. Nine-month-olds exhibited a faster P1 latency, marginally greater N290 amplitude and reduced P400 amplitude to labeled faces relative to a non-speech noise. However, 6-month-olds' neural responses did not differentiate monkey faces paired with labels from those paired with a non-speech noise until the second half of trials and only showed this effect for P1 latency and N290 amplitude. The results of this study suggest that overall, infants differentiate faces labeled with individual-level labels from those paired with a non-speech noise, however, 6-month-olds require more exposure to the label-face pairings than 9-month-olds. PMID- 29567098 TI - External and internal facial features modulate processing of vertical but not horizontal spatial relations. AB - Some years ago an asymmetry was reported for the inversion effect for horizontal (H) and vertical (V) relational face manipulations (Goffaux & Rossion, 2007). Subsequent research examined whether a specific disruption of long-range relations underlies the H/V inversion asymmetry (Sekunova & Barton, 2008). Here, we tested how detection of changes in interocular distance (H) and eye height (V) depends on cardinal internal features and external feature surround. Results replicated the H/V inversion asymmetry. Moreover, we found very different face cue dependencies for both change types. Performance and inversion effects did not depend on the presence of other face cues for detecting H changes. In contrast, accuracy for detecting V changes strongly depended on internal and external features, showing cumulative improvement when more cues were added. Inversion effects were generally large, and larger with external feature surround. The cue independence in detecting H relational changes indicates specialized local processing tightly tuned to the eyes region, while the strong cue dependency in detecting V relational changes indicates a global mechanism of cue integration across different face regions. These findings suggest that the H/V asymmetry of the inversion effect rests on an H/V anisotropy of face cue dependency, since only the global V mechanism suffers from disruption of cue integration as the major effect of face inversion. PMID- 29567099 TI - Short and long-term visual deprivation leads to adapted use of audiovisual information for face-voice recognition. AB - Person identification is essential for everyday social interactions. We quickly identify people from cues such as a person's face or the sound of their voice. A change in sensory input, such as losing one's vision, can alter how one uses sensory information. We asked how people with only one eye, who have had reduced visual input during postnatal maturation of the visual system, use faces and voices for person identity recognition. We used an old/new paradigm to investigate unimodal (visual or auditory) and bimodal (audiovisual) identity recognition of people (face, voice and face-voice) and a control category, objects (car, horn and car-horn). Participants learned the identity of 10 pairs of faces and voices (Experiment 1) and 10 cars and horns (Experiment 2) and were asked to identify the learned face/voice or car/horn among 20 distractors. People with one eye were more sensitive to voice identification compared to controls viewing binocularly or with an eye-patch. However, both people with one eye and eye-patched viewing controls use combined audiovisual information for person identification more equally than binocular viewing controls, who favour vision. People with one eye were no different from controls at object identification. The observed visual dominance for binocular controls is larger for person compared to object identification, indicating that faces (vision) play a larger role in person identification and that person identity processing is unique from that for objects. People with long-term visual deprivation from the loss of one eye may have adaptive strategies, such as placing less reliance on vision to achieve intact performance, particularly for face processing. PMID- 29567100 TI - Force-velocity profiling in older adults: An adequate tool for the management of functional trajectories with aging. AB - INTRODUCTION: The actual mechanisms leading to a reduced muscle power and functional ability in older adults are poorly understood. We investigated the association between different force-velocity (F-V) profiles and impaired muscle power, physical and cognitive function, frailty, and health-related quality of life (HRQoL) in older people. METHODS: Physical function (habitual gait speed, timed up-and-go test, sit-to-stand and stair-climbing ability), cognitive function, HRQoL and frailty were evaluated in 31 older subjects (70-85 years). The F-V relationship and maximal muscle power (Pmax) were assessed in the leg press exercise. The skeletal muscle index (SMI) and fat index, moderate-to vigorous physical activity (MVPA) and sedentary time were obtained from DXA scans and accelerometry, respectively. RESULTS: While some subjects showed a force deficit (FDEF), others presented a velocity deficit (VDEF), both leading to an impaired muscle power [Effect size (ES) = 1.30-1.44], and to a likely-very likely moderate harmful effect in their physical and cognitive function, HRQoL and frailty levels (except the VDEF group for cognitive function) [ES = 0.76-1.05]. Leg muscle mass and specific force were similarly associated with force at Pmax, while MVPA but not sedentary time was related to fat index, force at Pmax, and power values (all p < 0.05). A trend was found for the negative association between fat index and relative Pmax (p = 0.075). CONCLUSION: Older subjects exhibited different mechanisms (force vs. velocity deficits) leading to impaired muscle power. Both deficits were associated with a lower physical function and quality of life, and a higher frailty, whereas only a force deficit was associated with a lower cognitive function. Interventions aimed at reversing age- and/or disuse-related impairments of muscle power might evaluate the specific responsible mechanism and act accordingly. PMID- 29567101 TI - NaHS restores mitochondrial function and inhibits autophagy by activating the PI3K/Akt/mTOR signalling pathway to improve functional recovery after traumatic brain injury. AB - Traumatic brain injury (TBI) is one of the most serious public health problems in the world. TBI causes neurological deficits by triggering secondary injuries. Hydrogen sulfide (H2S), a gaseous mediator, has been reported to exert neuroprotective effects in central nervous system diseases, such as TBI. However, the molecular mechanisms involved in this effect are still unclear. The present study was designed to explore the ability of NaHS, a H2S donor, to provide neuroprotection in a mouse model of TBI and to discover the associated molecular mechanisms of these protective effects. Here, we found that administration of NaHS not only maintained the integrity of the blood brain barrier (BBB), protected neurons from apoptosis, and promoted remyelination and axonal reparation but also protected mitochondrial function. In addition, we found that autophagy was inhibited after treatment with NaHS following TBI, an effect that was induced by activation of the PI3K/AKT/mTOR signalling pathway. Our study indicated that H2S treatment is beneficial for TBI, pointing to H2S as a potential therapeutic target for treating TBI. PMID- 29567102 TI - A direct determination of AFBs in vinegar by aptamer-based surface plasmon resonance biosensor. AB - Aflatoxin (AFB) is one of the most toxic fungal metabolites produced by Aspergillus flavus, which may contaminate food and agricultural products. Herein, an aptamer-based surface plasmon resonance (SPR) biosensor was developed to detect AFBs. The chosen aptamer showed comparable interaction with the two AFBs, namely aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2). Such phenomenon was rarely reported, and might lead to a simultaneous detection of both AFBs. In this study, AFB1 was used to systematically establish the detection method. In the SPR system, streptavidin proteins were immobilized on the surface of a CM5 sensor chip as a cross-linker and biotin-aptamers were captured through streptavidin biotin interaction. After optimization, the assay showed a dynamic range between 0.09 and 200 ng mL-1 (linear range from 1.5 to 50 ng mL-1 and a LOD of 0.19 ng mL 1) of AFB1 in buffer. As expected, the aptasensor showed high specificity towards AFB1 and AFB2, but hardly bound to other toxins with similar structures, including ochratoxin A (OTA), ochratoxin B (OTB), Zeralenone (ZEA) and T-2 toxin (T-2). Determination of AFB1 in vinegar was further performed using the SPR biosensor. Recoveries of AFB1 from spiked samples ranged from 96.3 to 117.8%. The developed SPR assay is a simple, fast and sensitive approach for the detection of residual AFBs in agricultural products and foodstuffs like vinegar. PMID- 29567103 TI - Analysis of snake venom metalloproteinases from Myanmar Russell's viper transcriptome. AB - Snake venom metalloproteinases (SVMPs) are the key enzymes in Russell's viper (RV) venom which target all important components of haemostasis, such as clotting factors, platelets, endothelial cells and basement membrane. The structural diversity of SVMPs contributes to the broad spectrum of biological activities. The aim of the study was to investigate the SVMP transcript profile to gain better insights into the characteristic clinical manifestations of the Myanmar Russell's viper (MRV) bites that distinguish it from the RVs of other habitats. Next generation sequencing (RNA-Seq) of mRNA from MRV venom glands (2 males and 1 female) was performed on an Illumina HiSeq2000 platform and then de novo assembled using Trinity software. A total of 59 SVMP contigs were annotated through a Blastn search against the serpent nucleotide database from NCBI. Among them, disintegrins were the most abundant transcripts (75%) followed by the P-III class SVMPs (25%). The P-II SVMPs were scarce (0.002%), while no P-I SVMPs were detectable in the transcriptome. For detailed structural analysis, contigs were conceptually translated and compared with amino acid sequences from other RVs and other vipers using Clustal Omega. The RTS-disintegrin (jerdostatin homolog) was the most abundant among transcripts corresponding to 5 disintegrin isoforms. From 10 isoforms of SVMPs, RVV-X, and Vipera lebetina apoptosis-inducing protease (VLAIP) homolog, hereby termed Daboia siamensis AIP (DSAIP), were found to be highly expressed. Venom protein analysis using SDS-PAGE followed by mass spectrometry revealed that the disintegrin was scarce, while the latter two SVMPs were abundant. These two proteins can contribute to severe clinical manifestations caused by MRV envenomation. PMID- 29567104 TI - Predictors of a successful statin reattempt after an adverse reaction. AB - BACKGROUND: Many patients can tolerate statin therapy after an adverse reaction. However, optimal patient selection criteria and methods of reattempting statin therapy after an adverse reaction are unknown. OBJECTIVE: To identify patient and treatment characteristics associated with a successful statin reattempt after an adverse reaction. METHODS: We retrospectively studied adults treated in primary care practices affiliated with 2 academic medical centers between 2000 and 2012 who reattempted statin therapy after an adverse reaction. Statin reattempts were considered successful if the patient had at least 2 statin prescriptions after discontinuation of the original statin, and had an active electronic medical record statin record at 2 years after the adverse reaction. RESULTS: Among 6196 patients included in the study, 4536 (73.2%) successfully reattempted statin therapy. In multivariable analysis, history of coronary artery disease, stroke, or diabetes (odds ratio [OR] 1.195; P = .008) and reattempted treatment with a different statin (OR 1.463; P < .0001) were associated with greater odds of a successful reattempt. Adverse reaction during the first year after statin initiation (OR 0.721; P < .0001) or myalgia or myopathy (OR 0.807; P = .001) as well as history of adverse reactions to nonstatin drugs (OR 0.908; P < .0001) were associated with lower odds. CONCLUSIONS: Nature and timing of the adverse reaction, patient's medical history and the medication prescribed affected the likelihood of a successful reattempt of statin therapy after an adverse reaction. These findings suggest that a patient-centered approach to restarting statins should be considered for patients at high cardiovascular risk to improve the chances of success. PMID- 29567105 TI - Proximal and distal alignment of normal canine femurs: A morphometric analysis. AB - Many researchers are interested in femoral conformation because most orthopaedic problems of the long bones occur in the femur and its joints. The neck-shaft (NSA) and the anteversion (AVA) angles are good predictors for understanding the orientation of the proximal end of the femur. The varus (aLDFA) and procurvatum (CDFA) angles have also been used to understand the orientation of the distal end of the femur. The purposes of this study were to investigate the relationship between the proximal and distal angles of the femur and to compare the distal femoral angles in male and female dogs in order to investigate the sexual dimorphism. The measurements of normal CDFAs, which have not been previously reported, may also provide a database of canine distal femoral morphology. A total of 75 cleaned healthy femora from different breeds or mixed breed of dogs were used. The three-dimensional images were reconstructed from computed tomographic images. The AVA, NSA, aLDFA and CDFA were measured on the 3D images. The correlation coefficients were calculated among the measured angles. The distal femoral angles were also compared between male and female femora. The 95% confidence intervals of the AVA and the NSA were calculated to be 24.22 degrees 29.50 degrees and 144.97 degrees -147.50 degrees , respectively. The 95% confidence intervals of the aLDFA and the CDFA for all studied dogs were 92.62 degrees -94.08 degrees and 89.09 degrees -91.94 degrees , respectively. The NSA showed no correlation with either the aLDFA or CDFA. There was a weak inverse correlation between the AVA and CDFA and a weak positive correlation between the AVA and aLDFA. The differences in the aLDFA and CDFA measurements between male and female dog were not significant. In conclusion, femoral version, regardless of the plane, might have little influence on distal femoral morphology in normal dogs. Besides this, there is no evidence of a sexual dimorphism in the varus and procurvatum angles of the dog distal femur. The data from this study may be used in both orthopaedic studies and for clinical applications related to the distal femur of dogs. PMID- 29567106 TI - Scalable and cleavable polysaccharide nanocarriers for the delivery of chemotherapy drugs. AB - : While polysaccharide-based nanocarriers have been recognized for their crucial roles in tumor theranostics, the industrial-scale production of nanotherapeutics still remains a significant challenge. Most current approaches adopt a postpolymerization self-assembly strategy that follows a separate synthetic step and thus suffers from subgram scale yields and a limited range of application. In this study, we demonstrate the kilogram-scale formation of polysaccharide polyacrylate nanocarriers at concentrations of up to 5 wt% through a one-pot approach - starting from various acrylate monomers and polysaccharides - that combines aspects of hydrophobicity-induced self-assembly with the free radical graft copolymerization of acrylate monomers from polysaccharide backbones into a single process that is thus denoted as a graft copolymerization induced self assembly. We also demonstrate that this novel approach is applicable to a broad range of polysaccharides and acrylates. Notably, by choosing a crosslinker that bears a disulfide group and two vinyl capping groups to structurally lock the nanocarriers, the products are rendered cleavable in the reducing environments encountered at tumor sites and thus provide ideal candidates for the construction of anticancer nanotherapeutic systems. In vitro and in vivo studies demonstrated that the use of this nanocarrier for the delivery of doxorubicin hydrochloride (DOX) significantly decreased the side effects of DOX and improved the bio-safety of the chemotherapy accordingly. STATEMENT OF SIGNIFICANCE: While polysaccharide based nanocarriers have been recognized for their crucial roles in tumor theranostics, the industrial-scale production of these nanotherapeutics still remains a significant challenge. Most current approaches adopt a post polymerization self-assembly strategy which that follows a separate synthetic step, and thus suffers from sub-gram scale yields and a limited range of application. In this study, the hydrophobic effect was combined with free radical polymerization to facilitate the graft copolymerization-induced self-assembly (GISA) of acrylate monomers with various hydrophobicities to construct cleavable polysaccharide-polyacrylate nanocarriers at a high efficiency with excellent potential for industrial-scale production. We envision that these nanocarriers will contribute to the development of tumor nanotheranostics that combine the biological functionalities of polysaccharides with the unmatched application specific flexibility of nanocarriers. PMID- 29567107 TI - The role of the temporoparietal junction in implicit and explicit sense of agency. AB - The experience of being in control of one's actions and thier outcomes is called the sense of agency. This is a fundamental feature of our human experience, and may underpin important social functions such as morality and responsibility. Sense of agency can be measured explicitly, by asking people to report their experience, or implicitly by recording the perceived time interval between actions and outcomes (intentional binding). The current studies used transcranial direct current stimulation to assess the role of left and right temporoparietal junction in both implicit and explicit sense of agency. Participants were informed that they could control the volume output of the computer with one of two buttons. Participants experienced reduced sense of agency when the outcome was inconsistent with their action. However, binding did not differ between congruent and incongruent action-outcomes. The modulation of explicit agency ratings by action-outcome congruency was significantly reduced by right TPJ stimulation (experiment 1) but not left TPJ stimulation (experiment 2). Implicit agency was not affected in either stimulation condition. These findings are discussed in terms of the possible neural mechanisms of implicit and explicit sense of agency. PMID- 29567108 TI - Alternative outcomes create biased expectations regarding the received outcome: Evidence from event-related potentials. AB - After choosing between uncertain options, one might get feedback on both the outcome of the chosen option and the outcome of the unchosen option (the alternative). Behavioral research has shown that in such cases people engage in outcome comparison, and that the alternative outcome influences the way one evaluates his own received outcome. Moreover, this influence differs whether one was responsible or not for the choice made. In two studies, we looked for the electrophysiological correlates of outcome comparison. Subjects chose one of two boxes shown on the screen, each box contained a gain or a loss. The alternative outcome was always revealed first, followed by the received outcome. In half of the trials the software picked one box instead of subjects. We tested whether the feedback-related negativity (FRN) and the P3 elicited by the received reflect outcome comparison. As expected, we found that the FRN and P3 were more positive when the received outcome was a gain (vs. a loss). The FRN and P3 were also sensitive to the value of the alternative outcome, but contrary to our predictions, they were more positive when the alternative outcome was a gain (vs. a loss). As the FRN and P3 are sensitive to expectations, we hypothesized that our findings might result from subjects' biased expectations: subjects might have wrongly believed that a good (bad) alternative outcome signaled a bad (good) received outcome. This hypothesis, coined as the Alternative Omen Effect, was confirmed in parallel in a series of behavioral experiments: people see an illusory negative correlation between the uncorrelated outcomes of choice options (reported in Marciano-Romm et al. (2016)). A challenge for future research will be to disentangle the effects of expectation from those of outcome comparison. PMID- 29567109 TI - Diaphragmatic shear modulus at various submaximal inspiratory mouth pressure levels. AB - This study assessed the shear modulus of the diaphragm at various submaximal inspiratory mouth pressure levels by ultrasound shear wave elastography. In 14 healthy male subjects, diaphragmatic shear moduli were assessed at end expiration during resting breathing and at submaximal inspiratory tasks at 15, 30, 45, 60, and 75% of the maximal inspiratory mouth pressure. The shear modulus increased along with mouth pressure, and the mouth-pressure-shear-modulus relationship fit the second-order polynomial regression equation (r2 = 0.99 +/- 0.01; all subjects, r2 >= 0.95) better than it did the simple linear regression equation (r2 = 0.94 +/- 0.05; 8/14 subjects, r2 >= 0.95). The second regression coefficient in the second-order polynomial equation was a negative value in 10 of 14 subjects, which indicates that the second-order polynomial regression equation opened downwards. These findings suggest that the diaphragmatic shear modulus increases along with inspiratory mouth pressure, but the rate of increase slows when the pressure reaches higher levels. PMID- 29567110 TI - ROS generation and MAPKs activation contribute to the Ni-induced testosterone synthesis disturbance in rat Leydig cells. AB - Nickel (Ni) can disorder testosterone synthesis in rat Leydig cells, whereas the mechanisms remain unclear. The aim of this study was to investigate the role of reactive oxygen species (ROS) and mitogen-activated protein kinases (MAPKs) in Ni induced disturbance of testosterone synthesis in rat Leydig cells. The testosterone production and ROS levels were detected in Leydig cells. The mRNA and protein levels of testosterone synthetase, including StAR, CYP11A1, 3beta HSD, CYP17A1 and 17beta-HSD, were determined. Effects of Ni on the ERK1/2, p38 and JNK MAPKs were also investigated. The results showed that Ni triggered ROS generation, consequently resulted in the decrease of testosterone synthetase expression and testosterone production in Leydig cells, which were then attenuated by ROS scavengers of N-acetylcysteine (NAC) and 2,2,6,6-tetramethyl-1 piperidinyloxy (TEMPO), indicating that ROS are involved in the Ni-induced testosterone biosynthesis disturbance. Meanwhile Ni activated the ERK1/2, p38 and JNK MAPKs. Furthermore, Ni-inhibited testosterone synthetase expression levels and testosterone secretion were all alleviated by co-treatment with MAPK specific inhibitors (U0126 and SB203580, respectively), implying that Ni inhibited testosterone synthesis through activating ERK1/2 and p38 MAPK signal pathways in Leydig cells. In conclusion, these findings suggest that Ni causes testosterone synthesis disorder, partly, via ROS and MAPK signal pathways. PMID- 29567111 TI - Direct evidence of impaired neuronal Na/K-ATPase pump function in alternating hemiplegia of childhood. AB - Mutations in ATP1A3 encoding the catalytic subunit of the Na/K-ATPase expressed in mammalian neurons cause alternating hemiplegia of childhood (AHC) as well as an expanding spectrum of other neurodevelopmental syndromes and neurological phenotypes. Most AHC cases are explained by de novo heterozygous ATP1A3 mutations, but the fundamental molecular and cellular consequences of these mutations in human neurons are not known. In this study, we investigated the electrophysiological properties of neurons generated from AHC patient-specific induced pluripotent stem cells (iPSCs) to ascertain functional disturbances underlying this neurological disease. Fibroblasts derived from two subjects with AHC, a male and a female, both heterozygous for the common ATP1A3 mutation G947R, were reprogrammed to iPSCs. Neuronal differentiation of iPSCs was initiated by neurogenin-2 (NGN2) induction followed by co-culture with mouse glial cells to promote maturation of cortical excitatory neurons. Whole-cell current clamp recording demonstrated that, compared with control iPSC-derived neurons, neurons differentiated from AHC iPSCs exhibited a significantly lower level of ouabain sensitive outward current ('pump current'). This finding correlated with significantly depolarized potassium equilibrium potential and depolarized resting membrane potential in AHC neurons compared with control neurons. In this cellular model, we also observed a lower evoked action potential firing frequency when neurons were held at their resting potential. However, evoked action potential firing frequencies were not different between AHC and control neurons when the membrane potential was clamped to -80 mV. Impaired neuronal excitability could be explained by lower voltage-gated sodium channel availability at the depolarized membrane potential observed in AHC neurons. Our findings provide direct evidence of impaired neuronal Na/K-ATPase ion transport activity in human AHC neurons and demonstrate the potential impact of this genetic defect on cellular excitability. PMID- 29567112 TI - Reference intervals for measured and calculated free 25-hydroxyvitamin D in normal pregnancy. AB - The determination of free 25-hydroxyvitamin D (25(OH)D) as compared to the analysis of total 25-hydroxyvitamin D might reflect better the vitamin D status during pregnancy, since vitamin D-binding protein (DBP) concentrations increase throughout pregnancy and the vast majority of 25(OH)D is tightly bound to DBP thus strongly influencing total 25(OH)D. The concentration of the biologically active free 25(OH)D - on the other hand - is much less dependent on the DBP concentrations. The study was conducted in May-June 2016 in 368 Caucasian pregnant healthy women - residents of Northeastern Germany. Free 25(OH)D was either measured directly by commercial ELISA kit or assessed by calculation via total 25(OH)D, DBP, and albumin serum concentrations. Regardless of the detection method, free 25(OH)D lowers in the 3rd trimester comparing to the 1st trimester (by 12% and 21%, p < 0.05 and p < 0.001, for measured and calculated free 25(OH)D, respectively), whereas total 25(OH)D was not decreased in late pregnancy. DBP rises with gestational age. Total 25(OH)D was not correlated with serum calcium (p = 0.251), whereas free 25(OH)D was significantly (p = 0.007 for measured free 25(OH)D and p < 0.001 for calculated free 25(OH)D) positively correlated with calcium. All 25(OH)D isoforms were significantly negatively correlated with bone-specific alkaline phosphatase (BSAP), however the correlation strength was the lowest with total 25(OH)D (rho = -0.108, p = 0.038), whereas both measured and calculated free 25(OH)D revealed better associations with BSAP (rho = -0.203 and rho = -0.211 for measured and calculated free 25(OH)D, respectively, p < 0.001 for both). We established pregnancy trimester specific reference intervals for free measured and calculated 25(OH)D and DBP. Both measured and calculated free 25(OH)D showed better correlations with parameters of the endocrine vitamin D system (calcium and BSAP). Both ways of measuring free 25(OH)D in pregnant women are suitable as novel laboratory parameter for vitamin D status monitoring during human pregnancy and might replace in the future the routine total 25(OH)D assessment. PMID- 29567113 TI - Perception of the quality of care, work environment and sleep characteristics of nurses working in the National Health System. AB - OBJECTIVE: To describe nurses' perception in relation to the quality of care and their work environment, as well as to describe their quality of sleep. To analyze the relationship between ward and work shift with nurses' perception of their work environment, sleep quality and day time drowsiness. METHODS: A multicentre, observational and descriptive study carried out between 2012-2014 in seven hospitals of the Spanish National Health System. Work environment, work satisfaction, sleep quality and quality of patient care were evaluated through validated tools. RESULTS: 635 registered nurses participated in the study. Eighty three point seven percent perceived the quality of cares as good/excellent, and 55.1% rated the work environment of their hospital as good/excellent. PES-NWI classified 39% of hospitals as unfavourable and 20% as favourable. Fifteen point four percent of the nurses had a high level of burnout and 58.3% had low burnout. Sleep quality was 6.38 for nurses working on day shifts, 6.78 for the rotational shifts and 7.93 for night shifts. Significant differences were found between subjective sleep quality score, sleep duration, sleep disturbances and daytime dysfunction. CONCLUSIONS: In the provision of quality care services, there is a multitude of related factors such as shift, ward, satisfaction, and nurses' perceptions of patient safety and sleep quality. PMID- 29567114 TI - Human skin barrier formation takes place via a cubic to lamellar lipid phase transition as analyzed by cryo-electron microscopy and EM-simulation. AB - The skin's permeability barrier consists of stacked lipid sheets of splayed ceramides, cholesterol and free fatty acids, positioned intercellularly in the stratum corneum. We report here on the early stage of skin barrier formation taking place inside the tubuloreticular system in the secretory cells of the topmost viable epidermis and in the intercellular space between viable epidermis and stratum corneum. The barrier formation process was analysed in situ in its near-native state, using cryo-EM combined with molecular dynamics modeling and EM simulation. Stacks of lamellae appear towards the periphery of the tubuloreticular system and they are closely associated with granular regions. Only models based on a bicontinuous cubic phase organization proved compatible with the granular cryo-EM patterns. Only models based on a dehydrated lamellar phase organization agreed with the lamellar cryo-EM patterns. The data support that human skin barrier formation takes place via a cubic to lamellar lipid phase transition.

Although, Cyclins, CDKs and have been described to regulate endomitosis, the exact mechanism still remains an enigma. miRNA which were otherwise known as post transcriptional gene silencers are now emerging with various non-canonical functions including gene regulation at pre transcriptional level by miRNA binding at promoter region. Out of the many processes they regulate, miRNA have been manifested to play a role in megakaryocyte differentiation. In this study an attempt has been made to identify miRNA that could regulate cell cycle genes (Cyclins and CDKs) by targeting their promoters, during megakaryopoiesis. A new computational algorithm was implemented using Perl programming to identify putative targets of miRNA in CDK and Cyclin promoters. Perl script was also used to check nuclear localizing miRNA based on the presence of a consensus sequence. Real-time PCR was performed to analyze the expression of miRNA and their predicted targets in Dami vs. PMA treated Dami cells. Putative targets of miRNAs with longest, high complementarity matches in CDK/Cyclin promoters were obtained. We identified two significant miRNA, miR 1273g-3p and miR-619-5p with longest seed sequence matches. We further identified three main targets (CDK10, CDK11, Cyclin F) through which these two miRNA could regulate cell cycle during megakaryopoiesis. Our results reinforce the role of promoting targeting miRNA in regulation of cell cycle through certain CDK/Cyclins to support the process of endomitosis during megakaryopoiesis. PMID- 29567116 TI - Cardiovascular safety profile of a fixed-dose combination of glycopyrrolate and formoterol fumarate delivered via metered dose inhaler using co-suspension delivery technology. AB - BACKGROUND: Glycopyrrolate/formoterol fumarate (GFF) metered dose inhaler (MDI) is a fixed-dose combination of the long-acting muscarinic antagonist (LAMA), glycopyrrolate (GP), and the long-acting beta2-agonist (LABA), formoterol fumarate (FF), delivered via metered dose inhaler using innovative co-suspension delivery technology. Here we report the results of two studies that examined the cardiovascular safety of GFF MDI. METHODS: The thorough QT (TQT) study was a Phase I, randomized, double-blind, single-dose, crossover study to assess GFF MDI 18/9.6 (Bevespi Aerosphere(r)), GFF MDI 144/38.4 and GP MDI 144 MUg, compared with placebo MDI and open-label moxifloxacin 400 mg (active control) in healthy volunteers (PT003009). The cardiovascular safety study in patients with chronic obstructive pulmonary disease (COPD) was a Phase IIb, randomized, multicenter, double-blind, 14-day dosing, parallel-group study to evaluate GFF MDI 36/9.6, GP MDI 36 and FF MDI 9.6 MUg compared with open-label FF dry powder inhaler (DPI; Foradil(r) Aerolizer(r)) 12 MUg, in patients with moderate-to-severe COPD (PT003003 [NCT01349803]). RESULTS: Seventy healthy volunteers were randomized in the TQT study. GFF MDI 144/38.4, GFF MDI 18/9.6 and GP MDI 144 MUg all met the confidence interval-based criteria for negative QT prolongation potential. In the study in patients with COPD, 237 subjects were randomized and treated. GFF MDI 36/9.6, GP MDI 36, and FF MDI 9.6 MUg did not result in clinically meaningful changes from baseline in 24-h mean heart rate at Day 14 (primary endpoint) or in any of the other Holter monitoring endpoints at Day 14, compared with FF DPI 12 MUg. CONCLUSIONS: No clinically significant effects on cardiovascular safety occurred at therapeutic or supratherapeutic doses of GFF MDI, apart from a small and transient increase in heart rate following supratherapeutic dose of GFF MDI 144/38.4 MUg. Furthermore, there were no unexpected safety findings reported in either healthy volunteers or patients with COPD.

PMID- 29567118 TI - Cortical Hand Knob Stroke: Report of 25 Cases. AB - BACKGROUND: Although uncommon, cortical hand knob territory stroke is a well defined stroke entity that mimics peripheral nerve damage. Atherosclerosis and hypertension are the most prevalent risk factors for the disease. Embolic origin, either artery-to-artery or cardioembolic, has been suggested as the most probable underlying mechanism. MATERIALS AND METHODS: Twenty-five patients with isolated hand palsy due to central origin were admitted to our department between 2006 and 2016. Cortical lesions were proven by either computed tomography or magnetic resonance imaging. RESULTS: The average age was 67 +/- 12 years. Most of the cases were first-ever strokes (n = 23, 92%). Isolated infarct in the hand knob region was found in 18 of the 25 cases, whereas 7 had multiple acute infarctions. Supra-aortic atherosclerosis was found in 21 patients, 8 of them had 50% or greater ipsilateral stenosis of the internal carotid artery. Hypertension was the second most prevalent risk factor (n = 20, 80%). Quick improvement of symptoms was seen in almost every case (mean follow-up 17.5 months), 9 patients showed complete recovery, whereas 2 remained disabled and 1 died due to a malignant disease. Three patients suffered a recurrent stroke on follow-up. CONCLUSIONS: We conclude that distal arm paresis is a rare presentation of acute stroke with usually benign course.

PMID- 29567119 TI - Clinical Features, Surgical Treatment, and Long-Term Outcome in Children with Hemorrhagic Moyamoya Disease. AB - BACKGROUND: The objective of this study was to elucidate the clinical features, surgical treatment, and long-term outcome in pediatric patients with moyamoya disease (MMD). METHODS: We retrospectively reviewed 46 pediatric patients with hemorrhagic MMD at Beijing Tiantan Hospital. Clinical features, radiological findings, and outcomes were analyzed. RESULTS: The mean age at diagnosis was 13.6 +/- 3.6 years. The ratio of girls to boys was 1.0:1.1. Familial occurrence was 4.3%. The primary symptoms at initial presentation were intraventricular hemorrhage (IVH) (47.8%), intracerebral hemorrhage (ICH) (37.0%), ICH with IVH (13.0%), and subarachnoid hemorrhage (2.2%). Most patients presented with Suzuki stage 3 or 4 MMD. Posterior cerebral artery involvement was observed in 22 (18.4%) patients. During the average follow-up of 126.1 +/- 96.0 months, 11 of 53 (20.8%) conservatively treated hemispheres and 1 of 36 (2.8%) surgically treated hemispheres experienced a stroke event (P < .05). There was a difference in the Kaplan-Meier curve of stroke between the 2 groups (log rank test, P < .05). What is more, the rate of perfusion improvement in surgically treated patients was higher than in those conservatively treated patients 3 months after discharge (P < .05). CONCLUSIONS: Revascularization surgery has a role in the prevention of recurrent strokes and can improve cerebral perfusion in pediatric patients with hemorrhagic MMD. Further study is needed to determine which bypass surgery is more beneficial for pediatric patients with hemorrhagic MMD. PMID- 29567121 TI - Parent Involvement in the Pediatric Resident Applicant Interview. AB - BACKGROUND: Parents and patients are actively involved in the clinical learning environment, yet scant literature exists about their involvement in the residency interview process. We aimed to pilot a process of including parents in resident interviews and to determine its value. METHODS: During the 2016-17 residency interview cycle, 22 parent volunteers, blinded to applicant credentials, conducted brief structured interviews with 118 applicants. We then surveyed all parents and applicants with the use of mixed methods: descriptive statistics to analyze 5-point Likert-type-scale responses, and content analysis to identify themes from open-ended questions. Although parent interviews were not used in ranking, we later compared final composite parent interview scores (1-10, with 10 being high) among the final rank and match list candidates. RESULTS: Response rates were high for both groups (parents 100%; resident applicants 98.3%). Parents felt strongly positive about meeting applicants (mean +/- SD, 5.00 +/- 0.00), the value of parent participation (4.90 +/- 0.30), and their own experience (4.95 +/- 0.22). Applicants felt positive about meeting parents (4.45 +/- 0.70), the value of parent participation (3.92 +/- 0.84), and their own experience (4.51 +/- 0.67). Several themes emerged from both groups, with the most salient parent themes including the value of patient-centered perspectives and appreciation and joy of meeting applicants. Parent interview scores correlated with the final match list, with matched applicants scoring higher (9.08 vs 8.51; P = .05). CONCLUSIONS: Involvement of parents in the pediatric residency interview process is achievable, is perceived positively by parents and applicants, and may provide valuable perspectives for consideration in residency selection. PMID- 29567122 TI - Can three-dimensional pelvimetry using low-dose stereoradiography replace low dose CT pelvimetry? AB - PURPOSE: To evaluate the reliability of pelvimetric measurements performed using stereoradiographic imaging (SRI), and to assess maternal and fetal radiation doses compared to low-dose computer tomography (CT) pelvimetry. MATERIALS AND METHODS: Thirty-five pregnant women (mean age, 29.6+/-5.5 [SD] years; range: 20 41 years) were prospectively included. All women underwent simultaneous frontal and lateral low-dose SRI and low-dose CT examination of the pelvis. Pelvimetry measurements were obtained from both examinations and radiation doses obtained with the two techniques were compared. RESULTS: SRI-CT correlation (Pearson coefficient correlation [r]; mean bias [mb]) was strong for transverse inlet diameter (r=0.92; mb=-0.09cm), anteroposterior diameter of the pelvic inlet (r=0.92; mb = 0.47cm), maximal transverse diameter (r=0.9; mb=0.21cm), sacrum length (r=0.9; mb=0.09cm). Correlation was good. Correlation was good for the sacrum depth (r=0.75; mb=0.06cm) and Magnin's index (r=0.7; mb=0.5cm). Correlation was moderate for anteroposterior diameter of pelvic outlet (r=0.6; mb=0.52cm). The fetal dose was 13.1 times lower using SRI (87+/-26MUGy) than CT (1140+/-220MUGy, P<0.0001). The effective maternal dose was 3.1 times lower using SRI (97+/-21MUSv) than CT (310+/-60MUSv; P<0.0001). CONCLUSION: Pelvic inlet measurements using SRI are reliable. Compared to CT pelvimetry, SRI leads to a significant decrease in fetal and maternal radiation doses. These findings should prompt physicians to use SRI as the first-line approach for pelvimetry. PMID- 29567124 TI - Endoplasmic reticulum stress in pulmonary fibrosis. AB - Endoplasmic reticulum (ER) stress is associated with development and progression of fibrotic diseases, including idiopathic pulmonary fibrosis (IPF). ER stress was first implicated in the pathogenesis of IPF >15 years ago with the discovery of disease-causing mutations in surfactant protein C, which result in a misfolded gene product in type II alveolar epithelial cells (AECs). ER stress and the unfolded protein response (UPR) have been linked to lung fibrosis through regulation of AEC apoptosis, epithelial-mesenchymal transition, myofibroblast differentiation, and M2 macrophage polarization. Although progress has been made in understanding the causes and consequences of ER stress in IPF and a number of chronic fibrotic disorders, further studies are needed to identify key factors that induce ER stress in important cell types and define critical down-stream processes and effector molecules that mediate ER stress-related phenotypes. This review discusses potential causes of ER stress induction in the lungs and current evidence linking ER stress to fibrosis in the context of individual cell types: AECs, fibroblasts, and macrophages. As our understanding of the relationship between ER stress and lung fibrosis continues to evolve, future studies will examine new strategies to modulate UPR pathways for therapeutic benefit.

PMID- 29567123 TI - Fibrosis: Lessons from OMICS analyses of the human lung. AB - In recent decades there has been a significant shift in our understanding of idiopathic pulmonary fibrosis (IPF), a progressive and lethal disorder. While initially much of the mechanistic understanding was derived from hypotheses generated from animal models of disease, in recent decades new insights derived from humans with IPF have taken precedence. This is mainly because of the establishment of large collections of IPF lung tissues and patient cohorts, and the emergence of high throughput profiling technologies collectively termed 'omics' technologies based on their shared suffix. In this review we describe impacts of 'omics' analyses of human IPF samples on our understanding of the disease. In particular, we discuss the results of genomics and transcriptomics studies, as well as proteomics, epigenomics and metabolomics. We then describe how these findings can be integrated in a modified paradigm of human idiopathic pulmonary fibrosis, that introduces the 'hallmarks of aging' as a central theme in the IPF lung. This allows resolution of all the disparate cellular and molecular features in IPF, from the central role of epithelial cells, through the dramatic phenotypic alterations observed in fibroblasts and the numerous aberrations that inflammatory cells exhibit. We end with reiterating a call for renewed efforts to collect and analyze carefully characterized human tissues, in ways that would facilitate implementation of novel technologies for high resolution single cell omics profiling. PMID- 29567126 TI - Distribution of streptococcal groups causing infective endocarditis: a descriptive study. AB - The purpose of this study was to describe the distribution of streptococci causing infective endocarditis (IE). A total of 296 patients with definite IE admitted from July 2007 to December 2014 were identified, with microbial identification done by a combination of blood culture, valve culture, and valve polymerase chain reaction (PCR). The overall distribution of streptococci was 76% viridans (n = 224), 17% pyogenic (50), 6% nutritionally variant (17), and 2% anaerobic (5). Sixty-three (21%) viridans group streptococci were not identified further. The distribution of the remaining 161 viridans group streptococci was Streptococcus mitis group 61%, S. bovis group 15%, S. mutans group 13%, S. anginosus group 9%, and S. salivarius group 1%. Of the 50 pyogenic streptococci, 78% were S. agalactiae and 16% were S. dysgalactiae. PCR was significantly more sensitive than culture in identifying streptococci in excised heart valves. PMID- 29567127 TI - Poor yield of Clostridium difficile testing algorithms using glutamate dehydrogenase antigen and C. difficile toxin enzyme immunoassays in a pediatric population with declining prevalence of clostridium difficile strain BI/NAP1/027. AB - We compared the performance of algorithmic Clostridium difficile infection (CDI) diagnosis with four molecular tests in children. Stool samples in patients 1-18 years old were tested with an algorithm (C. Diff Quik Chek Complete (QCC) reflexed to illumigene C. difficile); AmpliVue C. difficile (ACD); Lyra Direct C. difficile (Lyra); BD MAX C diff (BDM); and Xpert C. difficile (XCD). The gold standard was positivity by two tests. Sensitivity, specificity, positive predictive value, and negative predictive value were 85%, 99%, 93%, 97% for the algorithm; 21%, 99%, 78%, 87% for QCC's toxin component; 94%, 99%, 94%, 99% for ACD; 88%, 99%, 94%, 98% for Lyra; 94%, 100%, 100%, 99% for BDM, and 94%, 99%, 94% and 99% for XCD. 9.6% of samples were ribotype 027. Algorithms may detect CDI with lower sensitivity compared to molecular methods in children. This may be related to low prevalence of NAP-1/ribotype 027. PMID- 29567128 TI - Oritavancin in vitro activity against gram-positive organisms from European and United States medical centers: results from the SENTRY Antimicrobial Surveillance Program for 2010-2014. AB - The in vitro activity of oritavancin was assessed against 44,715 gram-positive pathogens causing infections in European and United States (US) hospitals (2010 2014). There were no substantive differences (>+/-2-fold dilution) in oritavancin MIC50 or MIC90 values for different species/organism groups over time or by region. Oritavancin (99.9% susceptible) showed modal MIC, MIC50, and MIC90 results of 0.03, 0.03, and 0.06-0.12 mg/L when tested against Staphylococcus aureus, regardless of methicillin susceptibility, year, or region. Coagulase negative staphylococci from the US and Europe demonstrated equal MIC50 values for oritavancin (MIC50, 0.03 mg/L). Oritavancin inhibited 99.9% of Enterococcus faecalis and all E. faecium at <=0.5 mg/L, including vancomycin-resistant isolates. Oritavancin exhibited MIC50 results of 0.03 and <=0.008 mg/L when tested against beta-hemolytic and viridans group streptococci isolates, respectively, regardless of geographical region. Oritavancin maintained potent activity in vitro against this contemporary collection of European and US gram positive isolates over 5 years (2010-2014). PMID- 29567129 TI - [Statement by the Spanish Paediatric Association in relation to gender diversity in childhood and adolescence: Ethical and legal view from a multidisciplinary perspective]. AB - An ethical and legal view of gender diversity in childhood and adolescence is presented from the perspective of the best interest of the child and the principle of protection against vulnerability. The identification of gender diversity in childhood and adolescence is a process that requires support, coordination and a multidisciplinary team that improves care and helps to obtain evidence that is lacking today. Secure, equitable and comprehensive access to care and health care should be guaranteed when required. It is necessary to promote a changing of social outlook, capable of overcoming the stereotypes that lead to discrimination and increase suffering. Respect for gender diversity in childhood and adolescence is a fundamental Human Right. The recognition of a positive value in diversity is an ethical imperative. All of this, without forgetting that we are talking about minors often in contexts of vulnerability, and currently very uncertain, so prudence is the main rule that should guide decision-making.

AB - This review summarises the specific stakes of preoperative, intraoperative, and postoperative periods of patients with coronary artery disease undergoing non cardiac surgery. All practitioners involved in the perioperative management of such high cardiac risk patients should be aware of the modern concepts expected to decrease major adverse cardiac events and improve short- and long-term outcomes. A multidisciplinary approach via a functional heart team including anaesthesiologists, cardiologists and surgeons must be encouraged. Rational and algorithm-guided management of those patients should be known and implemented from preoperative to postoperative period. PMID- 29567131 TI - Midterm outcomes after aortic valve neocuspidization with glutaraldehyde-treated autologous pericardium. AB - OBJECTIVE: We had previously reported the short-term results of the aortic valve neocuspidization (AVNeo) procedure. We have now evaluated the midterm results with the longest follow-up of 118 months. METHODS: From April 2007 through December 2015, 850 patients were treated with AVNeo using autologous pericardium. Medical records of these patients were retrospectively reviewed. The procedure was on the basis of independent tricuspid replacement using autologous pericardium. The distances between the commissures were measured with an original sizing device, the pericardial cusp was trimmed using an original template, and then sutured to the annulus. RESULTS: There were 534 patients with aortic stenosis, 254 with aortic regurgitation, 61 with aortic stenoregurgitation, 19 with infective endocarditis, and 5 with a previous aortic valve procedure. Besides 596 patients with tricuspid aortic valve, 224 patients had bicuspid valve, 28 had unicuspid valve, and 2 had quadricuspid valve. There were 444 male and 406 female patients. The median age was 71 (range, 13-90) years old. Preoperative echocardiography revealed a peak pressure gradient average of 68.9 +/- 36.3 mm Hg with aortic stenosis. Surgical annular diameter was 20.9 +/- 3.3 mm. There was no conversion to a prosthetic valve replacement. There were 16 in hospital mortalities. Postoperative echocardiography revealed a peak pressure gradient average of 19.5 +/- 10.3 mm Hg 1 week after surgery and 15.2 +/- 6.3 mm Hg 8 years after surgery. Fifteen patients needed reoperation (13 infective endocarditis, 1 break of thread, and 1 tear of cusp case). The mean follow-up period was 53.7 +/- 28.2 months. Actuarial freedom from death, cumulative incidence of reoperation, and that of recurrent moderate aortic regurgitation or greater was 85.9%, 4.2%, and 7.3%, respectively, with the longest follow-up of 118 months. CONCLUSIONS: The midterm outcomes of AVNeo using autologous pericardium were satisfactory in 850 patients with various aortic valve diseases. However, further randomized, multicenter prospective studies are needed to confirm the results of the current study. PMID- 29567132 TI - Discussion. PMID- 29567133 TI - Expression analysis of immune genes in goldfish (Carassius auratus) infected with the monogenean parasite Gyrodactylus kobayashii. AB - Heavy infection with the ectoparasite Gyrodactylus kobayashii commonly leads to high mortality of ornamental goldfish Carassius auratus. To understand the underlying mechanisms of goldfish against infection of gyrodactylids, transcription responses of immune-related genes including IL-1beta2, TNFalpha1, TNFalpha2, IFN-gamma, TGFbeta, MHC II beta, TCRbeta1 and complement factor C3 were studied by real-time quantitative PCR analysis. Significant increases of expression of inflammatory genes such as IL-1beta2, TNFalpha1, TNFalpha2 and TGFbeta were detected at days 7 and 14 post-infection (pi). No significant differences of G. kobayashii load were observed in response to primary infection and re-infection. In addition, the transcript levels of genes involved in adaptive immunity such as MHC II beta and TCRbeta1 remained unchanged. Curiously, fish moderately infected with gyrodactylid showed elevated expression IL-1beta2, TNFalpha1 and TNFalpha2. In all the gyrodactylids-infected fish, expression of complement factor C3 was consistently inhibited. The results extend current knowledge to the understanding of gyrodactylid infection in fish and support the previous findings that innate immunity is indispensable for controlling parasite infection. PMID- 29567134 TI - A novel white spot syndrome virus-induced gene (MjVIG1) from Marsupenaeus japonicus hemocytes. AB - cDNA of a newly recognized white spot syndrome virus (WSSV)-induced gene (MjVIG1) was characterized from Marsupenaeus japonicus hemocytes; this gene encodes a protein that lack similarity to any known characterized protein. To identify this novel gene, we mainly conducted transcript level analysis, immunostaining and flow cytometry after WSSV infection. MjV1G1 transcript levels were also measured after Yellow head virus (YHV) and Vibrio parahaemolyticus infection tests. In non infected and WSSV-infected shrimp, MjVIG1 was observed in granule-containing hemocytes. In addition, the MjVIG1 transcript level and ratio of MjVIG1-positive hemocytes both significantly increased, and number of MjVIG1-positive hemocytes slightly increased after WSSV infection. In contrast, MjVIG1 transcript level did not change after YHV and V. parahaemolyticus infection. These results indicated that MjVIG1 might be a WSSV-specific induced gene in M. japonicus hemocytes. PMID- 29567135 TI - Class B CpG-ODN2006 is highly associated with IgM and antimicrobial peptide gene expression through TLR9 pathway in yellowtail Seriola lalandi. AB - The purpose of this study was to characterize the TLR9 gene from yellowtail (Seriola lalandi) and evaluate its functional activity using the class B Cytosine phosphate-guanine-oligodeoxynucleotide2006 (CpG-ODN2006) in an in vivo experiment after one-week immunostimulation. The gene expressions of TLR9, Immunoglobulin M (IgM), antimicrobial peptides and cytokines were evaluated by real time PCR, and humoral immune parameters were analyzed in serum. The TLR9 nucleotide sequence from yellowtail was obtained using the whole-genome shotgun sequencing method and bioinformatics tools. The yellowtail full-length cDNA sequence of SlTLR9 was 3789 bp in length, including a 66-bp 5'-untranslated region (UTR), a 3'-UTR of 528 bp, and an open reading frame (ORF) of 3192 bp translatable to 1064 amino acid showing a high degree of similarity with the counterparts of other fish species and sharing common structural architecture of the TLR family, including LRR domains, one C-terminal LRR region, and a TIR domain. Gene expression studies revealed the constitutive expression of TLR9 mRNA in all analyzed tissues; the highest levels were observed in intestine, liver and spleen where they play an important role in the fish immune system. The expression levels of TLR9 after B class CpG-ODN2006 (the main TLR9-agonist) was significantly up-regulated in all analyzed tissues, with the high expression observed in spleen followed by intestine and skin. The CpG-B has been shown as a potent B cell mitogen, and interestingly, IgM mRNA transcript was up-regulated in spleen and intestine, which was highly correlated with TLR9 after CpG-ODN2006 stimulation. The antimicrobial peptides, piscidin and NK-lysine, were up-regulated in spleen and gill after CpG-ODN2006 injection with a high correlation (r >= 0.82) with TLR9 gene expression. Cytokine genes were up-regulated in spleen, intestine and skin after CpG-ODN was compared with the control group. No significant correlation was observed between TLR9 and IL-1beta, TNF-alpha and Mx gene expressions. The results showed that CpG-ODN2006 intraperitoneal injection enhanced lysozyme, peroxidase and superoxide dismutase activities in serum and demonstrated that CpG ODN2006 can induce a specific immune response via TLR9 in which IgM and antimicrobial peptides must have an important role in the defense mechanisms against infections in yellowtail. PMID- 29567136 TI - Vaccination of carp against SVCV with an oral DNA vaccine or an insect cells based subunit vaccine. AB - We recently reported on a successful vaccine for carp against SVCV based on the intramuscular injection of a DNA plasmid encoding the SVCV glycoprotein (SVCV-G). This shows that the intramuscular (i.m.) route of vaccination is suitable to trigger protective responses against SVCV, and that the SVCV G-protein is a suitable vaccine antigen. Yet, despite the general success of DNA vaccines, especially against fish rhabdoviruses, their practical implementation still faces legislative as well as consumer's acceptance concerns. Furthermore, the i.m. route of plasmid administration is not easily combined with most of the current vaccination regimes largely based on intraperitoneal or immersion vaccination. For this reason, in the current study we evaluated possible alternatives to a DNA based i.m. injectable vaccine using the SVCV-G protein as the vaccine antigen. To this end, we tested two parallel approaches: the first based on the optimization of an alginate encapsulation method for oral delivery of DNA and protein antigens; the second based on the baculovirus recombinant expression of transmembrane SVCV-G protein in insect cells, administered as whole-cell subunit vaccine through the oral and injection route. In addition, in the case of the oral DNA vaccine, we also investigated the potential benefits of the mucosal adjuvants Escherichia coli lymphotoxin subunit B (LTB). Despite the use of various vaccine types, doses, regimes, and administration routes, no protection was observed, contrary to the full protection obtained with our reference i.m. DNA vaccine. The limited protection observed under the various conditions used in this study, the nature of the host, of the pathogen, the type of vaccine and encapsulation method, will therefore be discussed in details to provide an outlook for future vaccination strategies against SVCV. PMID- 29567137 TI - Wnt gene family members and their expression profiling in Litopenaeus vannamei. AB - The Wnt gene family encodes secreted glycoproteins involved in a wide variety of biological processes, including embryo development, cell proliferation and differentiation, and tissue regeneration. The Wnt pathway exists in all metazoan animals, however, the relevant research is rare in crustaceans. Here we described 12 Wnt genes representing 12 Wnt gene subfamilies in the Pacific white shrimp, Litopenaeus vannamei. Based on homolog annotations and phylogenetic analyses, we named these 12 Wnt genes as LvWnt1, LvWnt2, LvWnt4-11, LvWnt16, and LvWntA. All the corresponding LvWnt proteins shared a conserved Wnt1 domain and 22 conserved cysteine residues. LvWnt1 and LvWnt6 were adjacent in a scaffold in the shrimp genome. Furthermore, we performed expression analyses of LvWnt genes at different developmental stages, during the molting process, in different tissues and after different pathogenic infection. We showed that each LvWnt gene had a unique expression pattern at different developmental stages but only a few of them expressed in adult shrimp. All the investigated LvWnt genes were initially expressed at the gastrula or limb bud embryo stages. Among them, LvWnt8 was specifically high expressed only in early embryos. LvWntA and LvWnt5 displayed high and similar expression profiles during the molting process, and LvWnt6 and LvWnt16 were specifically expressed in the thoracic ganglion, ventral nerve, intestines and gill tissues, respectively. We also found the expression of LvWntA, LvWnt5, LvWnt6, LvWnt9, and LvWnt16 were varied in the different tissues after infected with Staphylococcus aureus, Vibrio parahaemolyticus and white spot syndrome virus (WSSV), which indicated that they might participate in immune response in L. vannamei. This study provided an insight into the repertoire of the Wnt gene structure and expression in shrimps, and furthermore, might promote the understanding of development, growth and immune response of shrimps and crustaceans. PMID- 29567139 TI - Transcriptome analysis of Pacific white shrimp (Litopenaeus vannamei) challenged by Vibrio parahaemolyticus reveals unique immune-related genes. AB - Pacific white shrimp (Litopenaeus vannamei) is an important cultural species worldwide. However, Vibrio spp. infections have caused a great economic loss in Pacific white shrimp culture industry. The immune responses of Pacific white shrimp to the Vibrio spp. is not fully characterized. In this study, the transcriptomic profiles of L. vannamei hemocytes were explored by injecting with or without Vibrio parahaemolyticus. Totally, 42,632 high-quality unigenes were obtained from RNAseq data. Comparative genome analysis showed 2258 differentially expressed genes (DEGs) following the Vibrio challenge, including 1017 up regulated and 1241 down-regulated genes. Eight DEGs were randomly selected for further validation by quantitative real-time RT-PCR (qRT-PCR) and the results showed that are consistent with the RNA-seq data. Due to the lack of predictable adaptive immunity, shrimps rely on an innate immune system to defend themselves against invading microbes by recognizing and clearing them through humoral and cellular immune responses. Here we focused our studies on the humoral immunity, five genes (SR, MNK, CTL3, GILT, and ALFP) were selected from the transcriptomic data, which were significantly up-regulated by V. parahaemolyticus infection. These genes were widely expressed in six different tissues and were up-regulated by both Gram negative bacteria (V. parahaemolyticus) and Gram positive bacteria (Staphylococcus aureus). To further extend our studies, we knock-down those five genes by dsRNA in L. vannamei and analyzed the functions of specific genes against V. parahaemolyticus and S. aureus by bacterial clearance analysis. We found that the ability of L. vannamei was significantly reduced in bacterial clearance when treated with those specific dsRNA. These results indicate that those five genes play essential roles in antibacterial immunity and have its specific functions against different types of pathogens. The obtained data will shed a new light on the immunity of L. vannamei and pave a new way for fighting against the bacterial infection in Pacific white shrimp. PMID- 29567138 TI - Inefficient immune response is associated with microbial permissiveness in juvenile oysters affected by mass mortalities on field. AB - Since 2008, juvenile Crassostrea gigas oysters have suffered from massive mortalities in European farming areas. This disease of complex etiology is still incompletely understood. Triggered by an elevated seawater temperature, it has been associated to infections by a herpes virus named OsHV-1 as well as pathogenic vibrios of the Splendidus clade. Ruling out the complexity of the disease, most of our current knowledge has been acquired in controlled experiments. Among the many unsolved questions, it is still ignored what role immunity plays in the capacity oysters have to survive an infectious episode. Here we show that juvenile oysters susceptible to the disease mount an inefficient immune response associated with microbial permissiveness and death. We found that, in contrast to resistant adult oysters having survived an earlier episode of mortality, susceptible juvenile oysters never exposed to infectious episodes died by more than 90% in a field experiment. Susceptible oysters were heavily colonized by OsHV-1 herpes virus as well as bacteria including vibrios potentially pathogenic for oysters, which proliferated in oyster flesh and body fluids during the mortality event. Nonetheless, susceptible oysters were found to sense microbes as indicated by an overexpression of immune receptors and immune signaling pathways. However, they did not express important immune effectors involved in antimicrobial immunity and apoptosis and showed repressed expression of genes involved in ROS and metal homeostasis. This contrasted with resistant oysters, which expressed those important effectors, controlled bacterial and viral colonization and showed 100% survival to the mortality event. Altogether, our results demonstrate that the immune response mounted by susceptible oysters lacks some important immune functions and fails in controlling microbial proliferation. This study opens the way to more holistic studies on the "mass mortality syndrome", which are now required to decipher the sequence of events leading to oyster mortalities and determine the relative weight of pathogens, oyster genetics and oyster-associated microbiota in the disease. PMID- 29567140 TI - Augmentation of the antibacterial activities of Pt5-derived antimicrobial peptides (AMPs) by amino acid substitutions: Design of novel AMPs against MDR bacteria. AB - The ever-growing concerns on multi-drug resistant (MDR) bacteria lead to urgent demands for novel antibiotics including antimicrobial peptides (AMPs). Pt5, a peptide consisting of the C-terminal 55 residues of zebrafish phosvitin, has been shown to function as an antibacterial agent. Here we used Pt5 as a template to design new AMPs by shortening the sequence and substituting with tryptophan (W) and lysine (K) at selected positions. Among the resultant Pt5-derived peptides, Pt5-1c showed the strongest antimicrobial activity against both Gram-negative and Gram-positive bacteria, including MDR bacteia, with the minimum inhibitory concentrations (MICs) ranging from 1.2 MUM to 4.8 MUM. Electron microscopic examination showed that Pt5-1c was able to kill the bacteria directly. ELISA revealed that Pt5-1c possessed high affinity to lipopolysaccharide (LPS), lipoteichoic acid (LTA) and peptidoglycan (PGN). Importantly, Pt5-1c was able to disrupt the bacterial membrane by a combined action of membrane depolarization and permeabilization, with little cytotoxicity to mammalian cells. Taken together, these findings suggest that Pt5-1c has considerable potential for future development as novel peptide antibiotics against MDR bacteria. PMID- 29567141 TI - Intra-muscular and oral vaccination using a Koi Herpesvirus ORF25 DNA vaccine does not confer protection in common carp (Cyprinus carpio L.). AB - Koi Herpes Virus (KHV or Cyprinid Herpesvirus 3, CyHV-3) is among the most threatening pathogens affecting common carp production as well as the highly valuable ornamental koi carp. To date, no effective commercial vaccine is available for worldwide use. A previous study reported that three intramuscular injections with an ORF25-based DNA vaccine, led to the generation of neutralizing antibodies and conferred significant protection against an intraperitoneal challenge with KHV. In the present study, we set out to optimize an ORF25-based DNA vaccination protocol that required fewer injections and would confer protection upon a challenge that better resembled the natural route of infection. To this end, ORF25 was cloned in pcDNA3 either as a soluble protein or as a full length transmembrane GFP-fusion protein. We tested our ORF25-based DNA vaccines in multiple vaccination trials using different doses, vaccination routes (i.m. injection and oral gavage) and challenge methods (bath and cohabitation). Furthermore, we analysed local and systemic responses to the i.m. injected DNA vaccine through histological and RT-qPCR analysis. We observed a strong protection when fish received three injections of either of the two DNA vaccines. However, this protection was observed only after bath challenge and not after cohabitation challenge. Furthermore, protection was insufficient when fish received one injection only, or received the plasmid orally. The importance of choosing a challenge model that best reflects the natural route of infection and the possibility to include additional antigens in future DNA vaccination strategies against KHV will be discussed. PMID- 29567142 TI - Molecular characterization and function analysis of grouper (Epinephelus coioides) Bruton's tyrosine kinase BTK. AB - Bruton's tyrosine kinase (BTK) is a Tec-family tyrosine kinase and plays a crucial role in B cell antigen receptor (BCR) signal pathway. Mutations in humans and mice BTK gene results in X-linked agammaglobulinemia (XLA) and X-linked immunodeficiency (XLD), respectively. To study the function of BTK in teleost, we cloned a BTK gene from orange-spotted grouper. Homology analysis showed that the grouper BTK (EcBTK) had a high amino acid identity with other vertebrates (63% 92%) and shared the highest amino acid identity with ballan wrasse Labrus bergylta BTK. EcBTK comprises a Bruton's tyrosine kinase pleckstrin homology (PH) domain, a Tec homology (TH) domain, a Src homology 3 (SH3) domain, a Src homology 2 (SH2) domain and a Protein Kinases, catalytic (PKc) domain. Tissue distribution analysis showed that EcBTK was mainly expressed in immune organs. EcBTK was uniform distributed throughout the cytoplasm of transfected HEK293T cells and overexpression of EcBTK slightly down-regulates NF-kappaB activity. Ibrutinib treatment can reduce the phosphorylation level of grouper's BTK. In groupers infected with Cryptocaryon irritans, up-regulation of EcBTK were not seen in the early stage of infected skin and gill until days 14-21. The phosphorylation level of grouper BTK was significantly increased in infected skin and gill. PMID- 29567143 TI - Regulation of stress signaling pathways by nitro-fatty acids. AB - Electrophilic nitrated-fatty acids (NO2-FA, nitroalkenes) are formed during reactions of NO-derived oxidized species (*NO, *NO2) with either free or esterified polyunsaturated fatty acids. Due to their electrophilic character, they react with nucleophiles such as cysteine thiols in signaling proteins, thereby triggering downstream signaling cascades. Herein, we review two stress signaling pathways activated by nitroalkenes, the KEAP1-NRF2 signaling pathway and the heat shock response (HSR) pathway. In addition, their biological and pharmacological relevance are discussed. Given that perturbations in both proteostasis and redox balance are common in many disease processes, dual activation of both pathways by nitroalkenes is a promising pharmacological approach for their treatment. PMID- 29567144 TI - Molecular detection of novel circoviruses in ticks in northeastern China. AB - Novel circular single-stranded DNA (ssDNA) genomes have been found in various animals using high-throughput sequencing techniques. In this study, two circular ssDNA genomes were detected in adult ticks from northeastern China by Solexa sequencing and PCR. The two sequences shared a similar genomic organization to circoviruses, with genomes of 1936 bp (TiCV-1) and 1812 bp (TiCV-2), each including two major open read frames (ORFs), ORF1 and ORF2, encoding putative replicase and capsid proteins, respectively. The potential stem-loop structure of a circovirus was predicted in the intergenic region between the two ORFs. Sequence comparison showed that the genome of TiCV-2 was almost the same as that of TiCV-1, except for two deletions and several mutations, and they had a high identity of 71.3-72.9% with Raven circovirus. The infection rates of circoviruses were calculated by the maximum likelihood estimation as 3.2% (95% CI, 1.9-5.2%) for TiCV-1 in the investigated Haemaphysalis longicornis, and 1.2% (95% CI, 0.2 4.0%) for TiCV-2 in Ixodes crenulatus from Yichun of Heilongjiang Province. These results indicate that the two sequences are distantly related to known circovirus genomes and may represent novel species in the family Circoviridae. PMID- 29567145 TI - Antiplasmodial activity of tick defensins in a mouse model of malaria. AB - Malaria is a mosquito-borne disease affecting millions of people mainly in Sub Saharan Africa, Asia and some South American countries. Drug resistance to first line antimalarial drugs (e.g. chloroquine, sulfadoxine-pyrimethamine and artemisinin) is a major constrain in malaria control. Antimicrobial peptides (AMPs) have shown promising results in controlling Plasmodium spp. parasitemia in in vitro and in vivo models of infection. Defensins are AMPs that act primarily by disrupting the integrity of cell membranes of invasive microbes. We previously showed that defensins from the tick Ixodes ricinus inhibited significantly the growth of P. falciparum in vitro, a property that was conserved during evolution. Here, we tested the activity of three I. ricinus defensins against P. chabaudi in mice. A single dose of defensin (120 MUl of 1 mg/ml solution) was administered intravenously to P. chabaudi-infected mice, and the parasitemia was followed for 24 h post-treatment. Defensin treatment inhibited significantly the replication (measured as increases in parasitemia) of P. chabaudi after 1 h and 12 h of treatment. Furthermore, defensin injection was not associated with toxicity. These results agreed with the previous report of antiplasmodial activity of tick defensins against P. falciparum in vitro and justify further studies for the use of tick defensins to control malaria. PMID- 29567146 TI - A new lipid carrier protein in the cattle tick Rhipicephalus microplus. AB - Tick infestation in cattle reflects the main cause of economic loss to cattle producers. This is due to several reasons but mainly to their ability to feed on blood and generate a huge amount of eggs. Lipid transport in arthropods is achieved by highly specialized hemolymphatic lipoproteins, which resemble those described in vertebrate blood. Such lipoproteins continuously deliver lipids through the blood to growing eggs. The injection of radioactive [3H] palmitic acid into tick hemocoel showed that the gut, ovary, fat body and Gene's organ were the main organs of incorporation of this labeled fatty acid. The rate of [3H] palmitic acid incorporation by the organs was high up to 30 min after injection. The [3H] palmitic acid incorporated by these organs was later found in phospholipids and neutral lipids. Here, we describe the purification and characterization of a key player of lipid dynamics in tick hemolymph. The Rhipicephalus microplus lipid-apolipoprotein complex (RmLCP) is a new high density lipoprotein (1.18 g/mL), which accounts for over 90% of [3H] palmitic acid present in the hemolymph. It has a native molecular weight of 420 kDa and is composed of one subunit of 122 kDa. Protein identification analysis of RmLPC subunit showed two better hits: vitellogenin 2 (23% protein coverage) and vitellogenin 5 (29% protein coverage), respectively and similarities with hemolymphatic apolipoproteins of arachnids such as the tick Ixodes scapularis (80%), the mite Galendromus occidentalis (44%) and the spider Parasteatoda tepidariorum (43%) and also for the insects Locusta migratoria (45%), Drosophila melanogaster (42%) and Manduca sexta (47%) to vitellogenin 2 and tick Ixodes scapularis (83%), the crab Limulus polyphemus (55%) and the oyster Crassostrea gigas (55%) to vitellogenin 5. Furthermore, it shows a distinct lipid composition from most arthropod lipoproteins, being composed of 40% free cholesterol, 27% phospholipids, 20% triacylglycerol and 15% hydrocarbons. In addition to binding most hemolymphatic fatty acids, this lipoprotein also binds and transports free cholesterol. In conclusion, the present study provides insight into the macromolecules involved in arachnid metabolism, which have significant potential for future use for the biological control of ticks. PMID- 29567148 TI - Research on Piroplasmorida and other tick-borne agents: Are we going the right way? AB - The use of molecular diagnostic techniques in the study of ticks and tick-borne agents has increased dramatically in the last few decades, and while conferring the advantages of rapidity, sensitivity and accuracy, they can also be misused by the research community, who have shown an increasing overreliance on the data they produce, often completely abandoning more traditional approaches such as microscopy and serology. In this short review examples are provided of 'findings' that are apparently at odds with well-established eco-epidemiological knowledge, ranging from descriptions of new species of pathogens to their detection in new hosts and ticks, often immediately incriminated as new reservoir hosts and vector ticks, respectively. Most examples have been taken from the Piroplasmorida or "piroplasm" species as they are often called. Researchers are urged to utilize molecular methods with as much awareness as possible of the system or systems they are investigating, and journal editors and their teams of reviewers should be encouraged to adopt a more critical approach to papers that contain data based solely on molecular methods without due regard to the underlying biology. Explanations for such findings should be offered and discussed. PMID- 29567147 TI - Anaplasma species detected in Haemaphysalis longicornis tick from China. AB - Anaplasma are tick-borne obligatory intracellular bacteria, which infect humans and other animals. The Anaplasma species carried by ticks in China are not well studied. We collected 3145 questing Haemaphysalis longicornis ticks including 120 larvae, 2460 nymphs and 565 adults from vegetation in Jiaonan County, Shandong Province, China from 2013 to 2015. All ticks were examined for the presence of Anaplasma species by nested PCR amplification of the 16S rRNA gene. For further differentiation of A. capra from A. centrale, gltA and msp2 genes were sequenced for A. capra. Three Anaplasma species were detected in the nymph and/or adult ticks with the minimum infection rate of ticks as follows: 1.55% for A. bovis, 0.10% for A. phagocytophilum, and 0.03% for A. capra. These results indicated that the H. longicornis tick in Jiaonan County carried multiple Anaplasma species, which may be a challenge for public health in the studying area. PMID- 29567149 TI - Fabrication of a novel enzymatic electrochemical biosensor for determination of tyrosine in some food samples. AB - In this work, fabrication of a novel and ultrasensitive electrochemical biosensor based on immobilization of tyrosine hydroxylase onto palladium-platinum bimetallic alloy nanoparticles/chitosan-1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide/graphene-multiwalled carbon nanotubes IL/glassy carbon electrode for determination of L-tyrosine in some high tyrosine foods including cheese, egg and yogurt was reported. Immobilization of tyrosine hydroxylase onto the surface of the biosensor was performed by cross-linking tyrosine hydroxylase and chitosan through the addition of glutaraldehyde. Enzymatic biosensors employ the affinity and selectivity of catalytically active proteins towards their target molecules and here, the tyrosine hydroxylase selectively catalyzes the conversion of tyrosine to levodopa which can be oxidized at lower potentials than tyrosine. The modifications were characterized by electrochemical impedance spectroscopy, cyclic voltammetry, energy dispersive X-ray spectroscopic and scanning electron microscopy. Under optimal conditions, the biosensor detected tyrosine in concentration ranges of 0.01 * 10-9 to 8.0 * 10-9 mol L-1 and 8.0 * 10-9 to 160.0 * 10-9 mol L-1 with a limit of detection of 0.009 * 10-9 mol L-1. The biosensor was able to selective determination of tyrosine even in the presence of common interferents therefore, the biosensor was highly selective. The biosensor also showed good operational stability, antifouling properties, sensitivity, repeatability and reproducibility. PMID- 29567150 TI - Application of CE-ICP-MS and CE-ESI-MS/MS for identification of Zn-binding ligands in Goji berries extracts. AB - The identification of groups of ligands binding metals is a crucial issue for the better understanding of their bioaccessibility. In the current study, we have intended an approach for identification of Zn-binding ligands based on using capillary electrophoresis combined with inductively coupled plasma mass spectrometry (CE-ICP-MS) and tandem electrospray ionization mass spectrometry (CE ESI-MS/MS). The approach, which featured the use of the coupling of capillary electrophoresis with inductively coupled plasma mass spectrometry allows to separate and observe zinc ions present in complexes with respect to their size and charge and to identify nine compounds with zinc isotopic profile. CE-ICP-MS provides us with information about presence of zinc species and elemental information about zinc distribution. CE-ESI-MS/MS provide us with information about the most favorable Zn binding ligands: amino acids, flavonols, stilbenoids, fenolic acids and carotenoids. The presented work is the continuation of previous studies based on using LC-ESI-MS/MS, though, now we presented a new solutions with the possibility of changing detectors without changing the separation techniques, what is important without re-optimizing the method. The new presented method allows to identify the zinc-binding ligands in shorter time. PMID- 29567151 TI - Amplified electrochemiluminescence detection of DNA based on novel quantum dots signal probe by multiple cycling amplification strategy. AB - In the present work, we designed a unique enzyme-aided multiple amplification strategy for sensitive electrochemiluminescence (ECL) detection of DNA by using the amplified gold nanoparticles (GNPS)-polyamidoamine (PAMAM)-CdSe quantum dots (QDs) signal probe. Firstly, the novel GNPS-PAMAM dendrimers nanostructure with good biocompatibility and electroconductibility contains many amino groups, which can load a large number of CdSe QDs to develop amplified ECL signal probe. Then, the presence of target DNA activated the enzyme-assisted polymerization strand displacement cycling reaction, and a large number of the hairpin template was opened. Subsequently, the opened stem further interacted with the capture hairpin (HP) DNA on the electrode, and the GNPS-PAMAM-CdSe signal probe hybridized with the exposed stem of the HP to trigger the second new polymerization reaction. Meanwhile, the first cycle was generating abundant DNA triggers which could directly open the template. As a result of the cascade amplification technique, a large number of CdSe QDs signal probe could be assembled on the electrode, generating much amplified ECL signal for sensitive detection of target DNA. Thus, this novel QDs-based amplified ECL strategy holds great promise for DNA detection and can be further exploited for sensing applications in clinical diagnostics. PMID- 29567152 TI - Gold nanoparticle-based 2'-O-methyl modified DNA probes for breast cancerous theranostics. AB - MicroRNAs (miRNAs) are a class of small non-coding RNAs that regulated diverse cellular processes including differentiation, proliferation, apoptosis, metabolism and signal transduction pathways. An increasing number of data suggested that miRNA-21 could be identified as diagnostic and therapeutic biomarker for breast cancer. Meanwhile, inhibiting the function of miRNA-21, resulting in cells growth inhibition and apoptotic cells death. To realize miRNA 21detection and inhibition to diagnostic and therapeutic breast cancer cells, we developed gold nanoparticle-based 2'-O-methyl modified DNA probes (AuNP-2'-OMe DNA probes) for diagnostic and therapeutic breast cancer. Gold nanoparticles were functionalized with chemically modified miRNA-21 inhibitor to suppress the function of miRNA-21 for the therapeutic breast cancer, at the same time, fluorophore-labeled DNA molecules were hybridized with antimiRNA-21 for diagnostic breast cancer. The results showed that the 2'-O-methyl modified DNA can improve stability, increase binding affinity to target strands and enhance the therapeutic effects. The experimental results also demonstrated that antimiR 21 were efficiently introduced into the cells and knocked down miRNA-21 to inhibit its function, leading to growth inhibition and apoptotic cells death. We prospected that chemically modified miRNA-21 inhibitor based on gold nanoparticles would be as a promising diagnostic and therapeutic platform for breast cancer clinically. PMID- 29567153 TI - A novel amperometric biosensor based on covalently attached multilayer assemblies of gold nanoparticles, diazo-resins and acetylcholinesterase for the detection of organophosphorus pesticides. AB - Using an ionic layer-by-layer self-assembly technique, colloidal gold nanoparticles (AuNPs) and diazo-resins (DAR) were immobilised on the surface of a p-aminobenzenesulfonic acid-modified glassy carbon electrode to form a matrix composite membrane for acetylcholinesterase (AChE) immobilisation. Photo sensitive DAR was used as the assembly interlayer to convert the ionic bond into a covalent bond to improve the biosensor stability. These fabrication processes were followed by electrochemical impedance spectroscopy and cyclic voltammetry to verify the membrane formation. Because of the introduction of AuNPs/DAR/AChE biofilms, the modified electrode exhibited excellent electron transfer mediation and electrical conductivity. In addition, it exhibited high sensitivity in the range of linear concentration from 1.0 * 10-8 to 1.0 * 10-12 g L-1 with the detection limit of 5.12 * 10-13 and 5.85 * 10-13 g L-1 for malathion and methyl parathion, respectively. More importantly, the presented biosensor considerably improved stability because the electrostatic interaction was converted into covalent bonds by UV irradiation. It is a simple, cheap and stable method for quantitative detection of organophosphorus pesticides, and this method may pave a way for the sensitive, simple detection of different analytes without the need of expensive instrumentation. PMID- 29567154 TI - Facile preparation and characterization of new green emitting carbon dots for sensitive and selective off/on detection of Fe3+ ion and ascorbic acid in water and urine samples and intracellular imaging in living cells. AB - Carbon dots (CDs) have gained great attention as multifunctional materials because of their interesting properties and general applicability. However, there are some reports for the preparation of highly luminescent green-emitting CDs (G CDs), although these reports seem not to be extensible. Herein, new G-CDs (quantum yield: 27.2%) were synthesized from a facile hydrothermal treatment of p aminosalicylic acid and ethylene glycol dimethacrylate as both carbon and nitrogen source and cross-linking agent, respectively. The chemical composition and optical properties of the as-prepared G-CDs were successfully investigated using transmission electron microscopy, atomic force microscopy, dynamic light scattering, X-ray diffraction, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and fluorescence and UV-vis spectroscopies. Interestingly, the fluorescence intensity of G-CDs was selectivity quenched by Fe3+ in the range of 0.05-10.0 umol L-1, with a detection limit of 13.7 nmol L-1. Meanwhile, ascorbic acid found to reduce Fe3+ to Fe2+, thereby causing restoration of the fluorescence of G-CDs. The detection limit for ascorbic acid detection was estimated as 82.0 nmol L-1 over a linear range from 0.2 to 11.0 umol L-1. Furthermore, the designed sensing platform was successfully utilized to the detection of Fe3+ and ascorbic acid in water and urine samples and to intracellular imaging without surface modification. PMID- 29567155 TI - Development and validation of a hydrophilic interaction liquid chromatography method for the quantitation of impurities in fixed-dose combination tablets containing rosuvastatin and metformin. AB - A hydrophilic interaction liquid chromatography method with diode array detection (HILIC-DAD) was developed and validated for the simultaneous determination of impurities in extended-release fixed-dose combination tablets containing rosuvastatin and metformin in a ratio 1:100. The analytes were separated by hydrophilic interaction liquid chromatography using an XBridge(r)-HILIC analytical column under isocratic elution. The mobile phase was composed of ammonium formate at 150 mM containing 0.05% diethylamine (pH 8.5)/acetonitrile, 4/96 (v/v) and pumped at a flow rate of 0.5 mL min-1. Method validation was performed according to ICH guidelines. The calibration curves for rosuvastatin, metformin and their seven impurities showed good linearity (r > 0.994) within the calibration ranges tested. The intra- and inter-day R.S.D. values were less than 4.5%, while the relative percentage error Er was less than 2.7% for all compounds. Accelerated stability studies performed under various stress conditions including hydrolysis, oxidation and heat proved the selectivity of the procedure. A run time of less than 25 min for each sample made it possible to analyze a large number of samples per day. The method is the first reported application of HILIC for the analysis of impurities in fixed-dose combination tablets containing rosuvastatin and metformin and it can be used for the quality control of these drugs. PMID- 29567156 TI - Mutual factor analysis for quantitative analysis by temperature dependent near infrared spectra. AB - Temperature dependent near infrared (NIR) spectroscopy has been developed for analyzing multi-component mixtures and understanding the molecular interactions in solutions. In this work, a chemometric method named as mutual factor analysis (MFA) was proposed for the analysis of temperature dependent NIR spectra. The method extracts the common spectral feature contained in the spectra of different temperature or different concentration. The relative quantity of the extracted spectral feature is proportional to the temperature or concentration. From the spectra of water-glucose mixtures, both the spectral variations induced by temperature and concentration are obtained and the variations are correlated with the inducements, respectively, in a very good linearity. Serum samples were used for validation of the method. An acceptable calibration model with a good correlation coefficient (R2 = 0.8639) was obtained for glucose measurement. The relative deviations of the measured concentrations from the calibration model are in the range of -18.7-8.52%, which are in a reasonable level for clinical uses. More importantly, the calculations are based on the spectral information of water that has interactions with the analyte. This provides a new way for quantitative analyses of bio-systems. PMID- 29567157 TI - Magnetic solid-phase extraction of non-steroidal anti-inflammatory drugs from environmental water samples using polyamidoamine dendrimer functionalized with magnetite nanoparticles as a sorbent. AB - A novel polyamidoamine dendrimer functionalized with Fe3O4 nanoparticles (Fe3O4@PAMAM) had been fabricated and used as magnetic solid-phase extraction (MSPE) adsorbent. The Fe3O4@PAMAM nanocomposites were characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, field-emission scanning electron spectroscopy, elemental analytical, and thermal gravimetric analysis. The MSPE method coupled with high-performance liquid chromatography with an ultraviolet detection system was applied for the separation/analysis of non-steroidal anti-inflammatory drugs (NSAIDs). Major parameters affecting the extraction efficiency of the selected drugs were optimized. Under optimal conditions, the enrichment factors for the proposed method were 701835. The linear range, limit of detection, correlation coefficient (r), and relative standard deviation (RSD) were found to be 0.15-500 ng mL-1, 0.050.08 ng mL-1, 0.99320.9967, and 4.5-7.0% (n = 5, 0.2, 10 and 300 ng mL-1), respectively. The method was successfully applied to the determination of NSAIDs in the real water samples. The recoveries of spiked water samples were in the range of 93.6-98.9% with RSDs varying from 6.1% to 9.0%, showing the good accuracy of the method. PMID- 29567158 TI - Trace detection and photothermal spectral characterization by a tuneable thermal lens spectrometer with white-light excitation. AB - In the thermal lens experimental set-up we replaced the commonly employed pump laser by a halogen lamp, combined with an interference filter, providing a tuneable, nearly monochromatic pump source over the range of wavelengths 430-710 nm. Counter-propagating pump and probe beams are used and a 1 mm path-length sample cell together with the interference filter makes an optical cavity, providing amplification of the thermal lens signal, which leads to enhancement of the measurement sensitivity, and enables detection of absorbances on the order of 5 * 10-6. Amplified thermal lens signal allows us to replace the typical lock-in amplifier and digital oscilloscope with a silicon photodetector, Arduino, and a personal computer, offering the possibility for a compact, robust and portable device, useful for in-field absorption measurements in low concentration or weakly absorbing species. The use of a white light source for optical pumping, an interference filter for wavelength selection and direct diagnostic of the thermal lens signal increase the versatility of the instrument and simplifies substantially the experimental setup. Determination of Fe(II) concentrations at parts per billion levels was performed by the described white-light thermal lens spectrophotometer and the absorption spectrum for 50 MUgL-1 Fe(II)-1,10 phenanthroline was well reproduced with an average measurement precision of 4%. The obtained limits of detection and quantitation of Fe(II) determination at 510 nm are 3 ugL-1 and 11 ugL-1, respectively. The calibration curve was linear in the concentration range of LOQ-500 ugL-1 with reproducibility between 2% and 6%, confirming that this instrument provides good spectrometric capabilities such as high sensitivity, tuneability and good reproducibility. In addition, the versatility of the instrument was demonstrated by recording the photothermal spectrum of gold nanostructured material and determination of excitation wavelength with most efficient optical to thermal energy conversion, which differs considerably (cca 100 nm) from the absorption maximum of the investigated sample. PMID- 29567159 TI - A new colorimetric, near-infrared fluorescent probe for rapid detection of palladium with high sensitivity and selectivity. AB - A new type of colorimetric, fluorescent palladium (Pd) probe characterized with beaconing fluorescence signal in the quiet near-infrared (NIR) region (centered ~ 717 nm), recognition response time of approximately 3 min, limit of detection (LOD) down to 5.1 ppb, and excellent recognition specificity over a wide range of interfering metal cations was developed. It is believed that the probe underwent sequential Pd0-mediated oxidative addition and reduction elimination reactions, yielding typical D-pi-A molecular skeleton of the final reaction product capable of intramolecular charge transfer (ICT). The benzothiazole moiety of the probe molecular skeleton is believed to play a vital trole in shifting the beaconing fluorescence signal to the quiet NIR region and accelerating the Pd0 recognition process of the probe via the formation of the fluorescent reaction product with largely extended pi-delocalization. With unique advantages, the fluorescent probe we developed will find practical applications for detecting residual Pd with concentration below the safety margin in pharmacy and biomedical engineering. PMID- 29567160 TI - Flow based determination of Cr(VI) by adsorptive cathodic stripping voltammetry on an immobilized magnetic poly(ionic liquid) modified electrode. AB - In this work an electrochemical procedure for Cr(VI) flow based determination in tap water is presented. An AdCSV method was developed using a screen printed electrode modified with magnetic poly(1-allyl-3-methylimidazolium) chloride and the procedure does not require the addition of complexing agents in the solution unlike the methodologies reported so far for Cr(VI) determination. The flow based system is described and the control variables were studied in detail and optimized using a Taguchi parameters design. Under optimal conditions, the electrochemical sensor offered an excellent response to Cr(VI) and the limit of detection estimated from 3sigma was 0.5 ug L-1 (n = 3) allowing the analysis of tap water samples. The effect of interfering ions was also investigated below the maximum permissible limits for tap water according to Mexican standards. The presence of the magnetic particles on the sorbent allowed its easy modification on the electrode surface between each determination when removing the magnetic field placed in the wall-jet cell. Finally, the precision of the method was tested with tap water samples using standard addition method for Cr(VI) quantification and the accuracy was evaluated comparing the results with the dyphenylcarbazide method and by analyzing a certified water sample. The method shows good repeatability and reproducibility (%RSD less than 5%) making it feasible for Cr(VI) flow based determination and no significant difference is observed in the results obtained by both methods. PMID- 29567161 TI - Analysis of isomeric opioids in urine using LC-TIMS-TOF MS. AB - In the present work, a fast separation, identification and quantification workflow based on liquid chromatography coupled to trapped ion mobility in tandem with mass spectrometry (LC-TIMS-MS) is described for the analysis of common isomeric drugs of abuse and their metabolites in human urine. In particular, the analytical performance of LC-TIMS-MS is shown for identification based on retention time, collision cross section and accurate mass for three sets of common isomeric opioids and their deuterated analogs in urine. The LC-TIMS-MS analysis provided limits of detection of 1.4-35.2 ng/mL with demonstrated linearity up to 500 ng/mL, enabling discovery and targeted monitoring (DTM) of opioids in urine, with high precision in retention times (RT) (< 0.3%), collision cross sections (CCS) (< 0.6%) and mass accuracy (< 1 ppm) across multiple measurements using external calibration. A good agreement was observed between theoretical and experimental CCS from candidate structures optimized at the DFT/B3LYP level. The need for complementary liquid and mobility separations prior to mass analysis is shown for the analysis of complex mixtures, with mobility resolving power of 80-130. The reproducibility and high speed of LC-TIMS-MS analysis provides a powerful platform for drug and metabolite screening in biological matrices with higher precision and confidence than traditional LC multiple reaction monitoring (MRM) approaches.

AB - A simple method for direct measurement of uranium (238U) in seawater using triple quadrupole inductively coupled plasma mass spectrometry (ICP-MS) was established. The method provides a good analytical performance with respect to detection limit, accuracy, precision and sample throughput. During the method development and application, several interesting facts were observed: 1) Comparison results for reference material using different quantitation approaches indicate that isotope dilution (using 233U) is the most reliable to achieve accurate 238U measurement. The results obtained for direct 238U measurement in 50-fold diluted seawater samples (n = 112) also underline the difference between isotope dilution and internal (or external) standardization. 2) Appropriate dilution of seawater is important to minimize the matrix effect on the ICP-MS measurement and 20-50 dilution is recommended for natural seawater samples. 3) The sensitivity of ICP MS was observed to increase in the beginning of sample measurement, and then decrease with the continuous injection of samples, which is believed as a consequence of matrix effect from the seawater to the ionization efficiency in the plasma. 4) When measuring samples taken from large volume of seawater stored in immovable containers for relatively long period (i.e., several months), the uranium concentration and salinity data showed slightly increasing trends with the increase of water depth in the container. Therefore, cautions need to be paid in sampling representativeness when performing 238U measurement for such long term stored large volume samples.

AB - A method was developed to determine copper and zinc simultaneously in brass sample using a multiple ion-selective electrode array system and multivariate calibration techniques. The multiple ion-selective electrode array system was consisted of one pH electrode and eight ion selective electrodes which were formed using commercial ionophores and which are mainly sensitive copper and zinc. PCR, PLS1 which are multivariate calibration techniques were used to calibrate the multiple ion-selective electrode array system using five level multivariate calibration design and PCR method was selected as most suitable method. The measurements were performed at pH 10 in ammonia-ammonium chloride buffer. Copper and zinc content of a brass sample were determined by the calibrated multiple ion-selective electrode array system and the composition of brass sample was also determined by gravimetric method. The percentage amount of copper and zinc in brass sample were 64 +/- 1 and 26 +/- 2, respectively using the gravimetric method. The percentage results obtained in brass samples for copper and zinc were 63 +/- 3 and 24 +/- 3 by PCR method and 60 +/- 5 and 20 +/- 7 by PLS1 method, respectively. The obtained results were calculated for a 95% confidence level. PMID- 29567164 TI - A vertical flow paper-microarray assay with isothermal DNA amplification for detection of Neisseria meningitidis. AB - Paper-based biosensors offer a promising technology to be used at the point of care, enabled by good performance, convenience and low-cost. In this article, we describe a colorimetric vertical-flow DNA microarray (DNA-VFM) that takes advantage of the screening capability of DNA microarrays in a paper format together with isothermal amplification by means of Recombinase Polymerase Amplification (RPA). Different assay parameters such as hybridization buffer, flow rate, printing buffer and capture probe concentration were optimized. A limit of detection (LOD) of 4.4 nM was achieved as determined by tabletop scanning. The DNA-VFM was applied as a proof of concept for detection of Neisseria meningitidis, a primary cause of bacterial meningitis. The LOD was determined to be between 38 and 2.1 * 106 copies/VFMassay, depending on the choice of DNA capture probes. The presented approach provides multiplex capabilities of DNA microarrays in a paper-based format for future point-of-care applications. PMID- 29567165 TI - 3D-printed lab-on-valve for fluorescent determination of cadmium and lead in water. AB - In recent years, the development of 3D printing in flow analysis has allowed the creation of new systems with various applications. Up to now, 3D printing was mainly used for the manufacture of small units such as flow detection cells, preconcentration units or mixing systems. In the present study, a new 3D printed lab-on-valve system was developed to selectively quantify lead and cadmium in water. Different technologies were compared for lab-on-valve 3D printing. Printed test units have shown that stereolithography or digital light processing are satisfactory techniques for creating complex lab-on-valve units. The lab-on-valve system was composed of two columns, eight peripheral ports and a central port, and a coil integrating baffles to increase mixing possibilities. A selective extraction of lead was first carried out by TrisKem PbTM Resin column. Then, cadmium not retained on the first column was extracted on a second column of Amberlite(r) IR 120 resin. In a following step, lead and cadmium were eluted with ammonium oxalate and potassium iodide, respectively. Finally, the two metals were sequentially detected by the same Rhod-5NTM fluorescent reagent. This 3D printed lab-on-valve flow system allowed us to quantify lead and cadmium with a linear response from 0.2 to 15 ug L-1 and detection limits of 0.17 and 0.20 ug L-1 for lead and cadmium, respectively, which seems adapted for natural water analysis. PMID- 29567166 TI - Assessment of a colorimetric method for the measurement of low concentrations of peracetic acid and hydrogen peroxide in water. AB - The recent growing interest in peracetic acid (PAA) as disinfectant for wastewater treatment demands reliable and readily-available methods for its measurement. In detail, the monitoring of PAA in wastewater treatment plants requires a simple, accurate, rapid and inexpensive measurement procedure. In the present work, a method for analyzing low concentrations of PAA, adapted from the US EPA colorimetric method for total chlorine, is assessed. This method employs N,N-diethyl-p-phenylelnediamine (DPD) in the presence of an excess of iodide in a phosphate buffer system. Pink colored species are produced proportionally to the concentration of PAA in the sample. Considering that PAA is available commercially as an equilibrium solution of PAA and hydrogen peroxide (H2O2), a measurement method for H2O2 is also investigated. This method, as the one for the determination of PAA, is also based on the oxidation of iodide to iodine, with the difference that ammonium molybdate Mo(VI) is added to catalyze the oxidation reaction between H2O2 and iodide, quantifying the total peroxides (PAA+ H2O2). The two methods are suitable for concentration ranges from about 0.1-1.65 mg L-1 and from about 0.3-3.3 mg L-1, respectively for PAA and H2O2. Moreover, the work elucidates some relevant aspects related to the operational conditions, kinetics and the possible interference of H2O2 on PAA measurement. PMID- 29567167 TI - Update on thalassemia diagnosis: New insights and methods. AB - A novel approach based on Thermogravimetric analysis followed by Chemometrics (TGA/Chemometrics) is provided for Thalassemia diagnosis and a comprehensive study consisting of the coupled approach TGA/Chemometrics, the Complete Blood Count (CBC) and Red Blood Cell (RBC) indices is developed and results are compared. A number of 128 subjects were involved in this study included 16 thalassemia intermedia transfusion-dependent (TI-TD) patients, 18 thalassemia intermedia non transfusion-dependent (TI-NTD) patients, and 14 thalassemia major beta (TM-TD) patients. Thalassemic patients were found to be clearly distinct from healthy donors as a function of a different thermal behavior. The chemometric analysis identifies the differences in the composition of blood and a model of prediction for beta-thalassemia was developed and validated to distinguish all patients. TGA/Chemometrics method also permitted to differentiate thalassemic patients according to the severity of anaemia while the evaluation of the indices and the CBC are not able to identify TI-TD, TI-NTD and TM-TD patients at first level test. TGA/Chemometrics was successfully applied for thalassemia diagnosis with 100% of correct classification rate. Chemometric analysis demonstrated that red cell distribution width (RDW), haemoglobin (Hb) and RBC are the diagnostic features in thalassemia compared to mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). New insights into the significance of the haematological features were provided for an update of the thalassemia classification. PMID- 29567168 TI - Simple and label-free liquid crystal-based sensor for detecting trypsin coupled to the interaction between cationic surfactant and BSA. AB - Trypsin plays a central role in catalyzing the hydrolysis of peptide bonds, so a technique with simple operation is needed to monitor the activity of trypsin. Here a simple and label-free senor based on liquid crystals (LCs) was developed by employing bovine serum albumin (BSA) as the enzyme substrate and dodecyl trimethyl ammonium bromide (DTAB) as the controller for the alignment of LC. It was found that DTAB could form a self-assembled monolayer at the aqueous/LC interface to produce the dark optical images of LCs. And the addition of BSA could disturb the monolayer, so that the optical signal of LCs turned bright from dark. But the hydrolysis of BSA by trypsin resulted in the dark appearance. The sensing platform allows detection as low as 1 U/mL under the polarized light microscope based on at least three measurements. Moreover, this method was successfully applied in the detection of trypsin in human urines, suggesting its potential applications in clinic diagnosis. PMID- 29567169 TI - Complexometric and argentometric titrations using thread-based analytical devices. AB - This work describes analytical approaches based on simple complexometric and argentometric titrations leading to the color change of a novel microfluidic thread-based analytical device (uTAD). The device was fabricated from a cotton thread (15 cm) treated with indicator solution, providing an easy-to-use platform for rapid measurement of analyte concentration in aqueous solution. The thread was immobilized onto a support, being a polypropylene sheet or box platform, to facilitate loading of liquid samples. Interaction between the deposited reagents and analytes in the samples then occurred within a few minutes. This resulted in zones of color change with different lengths along the thread depending on the analyte concentration. The interaction zones can be analyzed by human eyes based on comparison of the zone lengths with the printed scales which are correlated with the analyte concentrations. Complexometric titration using uTADs was initially investigated for Mg(II) determination in water and rubber latex samples. These devices consisted of two threads which were pretreated with Eriochrome Black T (EBT) and then treated with ethylenediaminetetraacetic acid (EDTA) in N-cyclohexyl-3-aminopropanesulfonic acid (CAPS) buffer at pH 10. Both threads were tied together with a central knot before being attached to the box platform prior to the analysis. Load of sample solution (6 uL) resulted in the length of red-violet color product on the threads being proportional to the concentration of Mg(II) in waters and rubber latex samples with the working concentration range of 25-1000 mg L-1. In addition, uTAD with a supporting polypropylene sheet consisting of several threads treated with AgNO3 and K2CrO4 indicators was applied for argentometric titration of chloride ion in water and food seasoning samples. After sample loading (3 uL), the initially red-brown threads turned into white corresponding to formation of AgCl(s) on the threads with a working concentration range of 75-600 mg L-1. Greater selectivity towards Mg(II) and chloride compared with potential interference ions was also observed. All the developed MUTADs were applied for analysis of real samples which showed results being in agreement with those obtained by classical titrations. PMID- 29567170 TI - Ultrasensitive photoelectrochemical aptasensor for lead ion detection based on sensitization effect of CdTe QDs on MoS2-CdS:Mn nanocomposites by the formation of G-quadruplex structure. AB - An ultrasensitive photoelectrochemical (PEC) aptasensor for lead ion (Pb2+) detection was fabricated based on MoS2-CdS:Mn nanocomposites and sensitization effect of CdTe quantum dots (QDs). MoS2-CdS:Mn modified electrode was used as the PEC matrix for the immobilization of probe DNA (pDNA) labeled with CdTe QDs. Target DNA (tDNA) were hybridized with pDNA to made the QDs locate away from the electrode surface by the rod-like double helix. The detection of Pb2+ was based on the conformational change of the pDNA to G-quadruplex structure in the presence of Pb2+, which made the labeled QDs move close to the electrode surface, leading to the generation of sensitization effect and evident increase of the photocurrent intensity. The linear range was 50 fM to 100 nM with a detection limit of 16.7 fM. The recoveries of the determination of Pb2+ in real samples were in the range of 102.5-108.0%. This proposed PEC aptasensor provides a new sensing strategy for various heavy metal ions at ultralow levels.

AB - Polydopamine decorated in-situ with Localized Surface Plasmon Resonance (LSPR) active gold nanoparticles (AuNPs) may extend the applicability of nanoplasmonic materials to original and innovative applications in several fields. Here we report the modification of disposable UV-Vis polystyrene cuvettes with AuNPs@PDA for refractive index LSPR-based measurements. An original layer-by-layer deposition method of PDA followed by AuNPs growth is here developed, showing linear correlation between PDA thickness and optical properties. In particular, the modulation from wavelength sensitivity toward absorbance sensitivity is obtained, allowing measurements at fixed wavelength (578 nm). As applicative example of the photonic cuvettes, the measurement of fermentable sugars in beer wort is here reported. The analytical performance of our approach has been directly compared to portable refractometer of reference, displaying excellent results in terms of the precise estimation of sugars in beer wort (expressed in degrees Brix), reproducibility and sensitivity. The approach may be extended to other materials of interest in LSPR based optical sensors, e.g. optical fibers. PMID- 29567172 TI - Saliva as a source of new phosphopeptide biomarkers: Development of a comprehensive analytical method based on shotgun peptidomics. AB - The paper describes the development of an enrichment method for the analysis of the endogenous phosphopeptides in saliva. The method was based on magnetic solid phase extraction by a magnetic graphitized carbon black-TiO2 composite material and was developed considering different saliva pre-treatments, namely C18 solid phase extraction for purification, direct dilution in loading buffer or acetonitrile precipitation. The method was based on a shotgun proteomics workflow and the enriched peptide mixture was analysed by nanoHPLC and high resolution tandem mass spectrometry. Acetonitrile precipitation provided the best results, with up to 165 endogenous phosphopeptides identified in saliva samples from healthy individuals. The physico-chemical features of the identified endogenous phosphopeptides indicated that such peptides were large, hydrophilic and basic. PMID- 29567173 TI - A high throughput method for measuring cloth-air equilibrium distribution ratios for SVOCs present in indoor environments. AB - Accumulation of chemicals from the environment to clothing and other textiles can influence human uptake by several exposure routes. In this research, we demonstrate that the cloth-air equilibrium distribution ratio for species i, KCA_i, can be measured relatively easily and quickly using headspace analysis of cloth dosed with two common indoor air SVOCs, diethyl phthalate (DEP) and di-n butyl phthalate (DnBP). A known mass of a phthalate was applied to the cloth in a volatile solvent carrier. After evaporation of the solvent, the cloth was placed in a vial and allowed to equilibrate with the air in the vial. Since the volume of headspace air is small, the total mass required to transfer from cloth to air is small and also the time required for air equilibration with the fabric surface is very short (minutes). Distribution ratios for the two phthalate esters sorbed to cotton jean material, reported as the concentration in the bulk cloth divided by the air concentration, were measured at 20, 25, 32, and 40 degrees C. The volume-normalized distribution ratio, Kvol [(MUg/m3)/(MUg/m3)], ranged from (0.75 +/- 0.01)* 105 to (5.6 +/- 0.2) * 105 for DEP and (5 +/- 0.3)* 105 to (57 +/- 1) * 105 for DnBP. Mass-normalized distribution ratio, Kmass [m3/g], ranged from (0.25 +/- 0.01) to (1.8 +/- 0.1) for DEP and (1.6 +/- 0.1) to (18.5 +/- 0.5) for DnBP. The cloth-air distribution ratios obtained from this study compare favorably with previously published results using other methods. Although equilibration with air in the headspace can be rapid, diffusion into the textile fibers is a slower equilibration process. Overall, this simple method has the potential to rapidly generate distribution ratios for a large number of chemical textile pairs. PMID- 29567174 TI - Protein-mimicking nanowire-inspired electro-catalytic biosensor for probing acetylcholinesterase activity and its inhibitors. AB - A highly sensitive electrochemical biosensor based on the synthetized L-Cysteine Ag(I) coordination polymer (L-Cys-Ag(I) CP), which looks like a protein-mimicking nanowire, was constructed to detect acetylcholinesterase (AChE) activity and screen its inhibitors. This sensing strategy involves the reaction of acetylcholine chloride (ACh) with acetylcholinesterase (AChE) to form choline that is in turn catalytically oxidized by choline oxidase (ChOx) to produce hydrogen peroxide (H2O2), thus L-Cys-Ag(I) CP possesses the electro-catalytic property to H2O2 reduction. Herein, the protein-mimicking nanowire-based platform was capable of investigating successive of H2O2 effectively by amperometric i-t (current-time) response, and was further applied for the turn-on electrochemical detection of AChE activity. The proposed sensor is highly sensitive (limit of detection is 0.0006 U/L) and is feasible for screening inhibitors of AChE. The model for AChE inhibition was further established and two traditional AChE inhibitors (donepezil and tacrine) were employed to verify the feasibility of the system. The IC50 of donepezil and tacrine were estimated to be 1.4 nM and 3.5 nM, respectively. The developed protocol provides a new and promising platform for probing AChE activity and screening its inhibitors with low cost, high sensitivity and selectivity. PMID- 29567175 TI - Ligand-assisted magnetic solid phase extraction for fast speciation of silver nanoparticles and silver ions in environmental water. AB - In this work, poly(1-vinylimidazole) functionalized magnetic nanoparticles (PVIM MNPs) were prepared and adopted for the adsorption of silver nanoparticles (AgNPs) and silver ions (Ag ions). With the use of mercaptosuccinic acid as a ligand exchanger, both of AgNPs and Ag ions could be adsorbed on the PVIM-MNPs and the sequential desorption of Ag ions and AgNPs was easily achieved by using Na2S2O3 and HNO3, respectively. Based on it, a new approach by coupling ligand assisted magnetic solid phase extraction (MSPE) with graphite furnace atomic absorption spectrometry (GFAAS) detection was proposed for the speciation of AgNPs and Ag ions in environmental water samples. Factors affecting MSPE of AgNPs and Ag ions were investigated and the optimized conditions were established. With an enrichment factor of 100-fold, the detection limits of the proposed method were 7.5 and 8.2 ng L-1 for Ag ions and AgNPs with relative standard deviations of 6.4% and 7.0% (c = 50 ng L-1, n = 7), respectively. The proposed ligand assisted MSPE-GFAAS method has the advantages of high sensitivity, low cost and easy operation, and could be used for the quantification of Ag ions and various coating modified AgNPs with a size range of 5-120 nm in environmental waters. PMID- 29567176 TI - Direct solid phase microextraction combined with gas chromatography - Mass spectrometry for the determination of biogenic amines in wine. AB - A direct method based on immersion solid phase microextraction (DI-SPME) gas chromatography mass-spectrometry (GC-MS) was optimized and validated for the determination of 16 biogenic amines in Polish wines. In the analysis two internal standards were used: 1,7-diaminoheptane and bis-3-aminopropylamine. The method allows for simultaneous extraction and derivatization, providing a simple and fast mode of extraction and enrichment. Different parameters which affect the extraction procedure were studied and optimized including ionic strength (0-25%), fiber materials (PDMS/DVB, PDMS/DVD + OC, Polyacrylate, Carboxen/PDMS and DVB/CAR/PDMS) and timings of the extraction, derivatization and desorption processes. Validation studies confirmed the linearity, sensitivity, precision and accuracy of the method. The method was successfully applied to the analysis of 44 wine samples originating from several regions of Poland and 3 wine samples from other countries. Analysis showed that many of the samples contained all examined biogenic amines. The method, assessed using an Eco-Scale tool with satisfactory results, was found to be green in terms of hazardous chemicals and solvents usage, energy consumption and production of waste. Therefore the proposed method can be safely used in the wine industry for routine analysis of BAs in wine samples with a minimal detrimental impact on human health and the environment. PMID- 29567177 TI - Quantitative determination of total cesium in highly active liquid waste by using liquid electrode plasma optical emission spectrometry. AB - A sensitive analytical method for determination of total cesium (Cs) in highly active liquid waste (HALW) by using modified liquid electrode plasma optical emission spectrometry (LEP-OES) is developed in this study. The instrument is modified to measure radioactive samples in a glove box. The effects of important factors, including pulsed voltage sequence and nitric acid concentration, on the emission of Cs are investigated. The limit of detection (LOD) and limit of quantification (LOQ) are 0.005 mg/L and 0.02 mg/L, respectively. The achieved LOD is one order lower than that of recently developed spectroscopic methods using liquid discharge plasma. The developed method is validated by subjecting a simulated HALW sample to inductively coupled plasma mass spectrometry (ICP-MS). The recoveries obtained from a spike-and-recovery test are 96-102%, implying good accuracy. The method is successfully applied to the quantification of Cs in a real HALW sample at the Tokai reprocessing plant in Japan. Apart from dilution and filtration of the HALW sample, no other pre-treatment process is required. The results agree well with the values obtained using gamma spectrometry. The developed method offers a reliable technique for rapid analysis of total Cs in HALW samples. PMID- 29567178 TI - A paper-based analytical device for the determination of hydrogen sulfide in fuel oils based on headspace liquid-phase microextraction and cyclic voltammetry. AB - An easily performed miniaturized, cheap, selective and sensitive procedure for the determination of H2S in fuel oil samples based on a headspace liquid-phase microextraction followed by a cyclic voltammetry detection using a paper-based analytical device (PAD) was developed. A modified wax dipping method was applied to fabricate the PAD. The PAD included hydrophobic zones of sample and supporting electrolyte connecting by hydrophilic channel. The zones of sample and supporting electrolyte were connected with nickel working, platinum auxiliary and Ag/AgCl reference electrodes. The analytical procedure included separation of H2S from fuel oil sample based on the headspace liquid-phase microextraction in alkaline solution. Then, sulfide ions solution obtained and supporting electrolyte were dropped on the zones followed by analyte detection at + 0.45 V. Under the optimized conditions, H2S concentration in the range from 2 to 20 mg kg-1 had a good linear relation with the peak current. The limit of detection (3sigma) was 0.6 mg kg-1. The procedure was successfully applied to the analysis of fuel oil samples. PMID- 29567179 TI - A 3D-printed self-propelled, highly sensitive mini-motor for underwater pesticide detection. AB - A three-dimensionally printed self-propelled mini-motor (SPM) for the detection of underwater pollutants is proposed. The device uses highly sensitive metal nanoparticles for colorimetric monitoring. Gold nanoparticles covered with Rhodamine B (RB-AuNPs) were prepared, based on established colorimetric and fluorometric approaches for detecting pesticides. The detection mechanism monitors the inhibition of the activity of acetylcholinesterase (AChE) by the pesticide, in which the production of thiocholine from the hydrolysis of acetylthiocholine (ATCh) catalyzed by AChE is reduced. As a result, the color of the RB-AuNP solution remains red, and the fluorescence of RB remains quenched. The RB-AuNPs were characterized by transmission electron microscopy (TEM), UV-Vis absorption spectroscopy, and X-ray photoelectron spectroscopy (XPS). Under the optimized experimental conditions, excellent reproducibility (with a relative standard deviation of 5.8%) and low sensitivity limits, ranging from 0.4 to 3.0 MUg L-1, were achieved. The limit of quantity (LOQ) was 0.3 MUg L-1,and the detection limit (LOD) was 0.23 MUg L-1, which was much lower than the maximum residue limits reported in the European Union pesticide database. With the aid of 3D-printed SPMs and nano-colorimetry, both qualitative and quantitative analyses can be performed for pesticide detection in river water. This is the first time a 3D-printed SPM has been combined with nano-colorimetry to realize a convenient, cost-effective, and high sensitive detection method for pollutants in water. PMID- 29567180 TI - Equilibrium ex vivo calibration of homogenized tissue for in vivo SPME quantitation of doxorubicin in lung tissue. AB - The fast and sensitive determination of concentrations of anticancer drugs in specific organs can improve the efficacy of chemotherapy and minimize its adverse effects. In this paper, ex vivo solid-phase microextraction (SPME) coupled to LC MS/MS as a method for rapidly quantitating doxorubicin (DOX) in lung tissue was optimized. Furthermore, the theoretical and practical challenges related to the real-time monitoring of DOX levels in the lung tissue of a living organism (in vivo SPME) are presented. In addition, several parameters for ex vivo/in vivo SPME studies, such as extraction efficiency of autoclaved fibers, intact/homogenized tissue differences, critical tissue amount, and the absence of an internal standard are thoroughly examined. To both accurately quantify DOX in solid tissue and minimize the error related to the lack of an internal standard, a calibration method at equilibrium conditions was chosen. In optimized ex vivo SPME conditions, the targeted compound was extracted by directly introducing a 15 mm (45 um thickness) mixed-mode fiber into 15 g of homogenized tissue for 20 min, followed by a desorption step in an optimal solvent mixture. The detection limit for DOX was 2.5 ug g-1 of tissue. The optimized ex vivo SPME method was successfully applied for the analysis of DOX in real pig lung biopsies, providing an averaged accuracy and precision of 103.2% and 12.3%, respectively. Additionally, a comparison between SPME and solid-liquid extraction revealed good agreement. The results presented herein demonstrate that the developed SPME method radically simplifies the sample preparation step and eliminates the need for tissue biopsies. These results suggest that SPME can accurately quantify DOX in different tissue compartments and can be potentially useful for monitoring and adjusting drug dosages during chemotherapy in order to achieve effective and safe concentrations of doxorubicin. PMID- 29567181 TI - Electrochemical detection of c-reactive protein based on anthraquinone-labeled antibody using a screen-printed graphene electrode. AB - In this present work, a novel electrochemical immunosensor employing a screen printed graphene electrode (SPGE) for a simple and highly sensitive determination of C-reactive protein (CRP) in a sandwich-type format was proposed. The sensor comprised of two CRP-specific antibodies: an unlabeled capture primary antibody (Anti-1 degrees Ab) and an electrochemically detectable anthraquinone-labeled signaling secondary (AQ-2 degrees Ab) antibody. The Anti-1 degrees Ab was first covalently anchored onto an L-cysteine/gold-modified disposable SPGE (L Cys/Au/SPGE) to create the anti-CRP surface. After binding of the CRP and the AQ 2 degrees Ab, the electrochemical signal response was measured using differential pulse voltammetry (DPV). In the presence of CRP, the sensor exhibited a significant increase in the AQ current at AQ-2 degrees Ab compared to the negative control. The CRP concentration was detected in the range of 0.01-150 ug/mL, and the limit of detection (LOD) (S/N = 3) and limit of quantitation (LOQ) (10 SD/Slope) were 1.5 ng/mL and 10 ng/mL, respectively. This sensor exhibited very high sensitivity in determining CRP and was successfully applied to detect CRP in certified human serum with satisfactory results. The developed sensor is suitable as an alternative method for determination of CRP and the same principle may be further applied to determine other clinically important target molecules. PMID- 29567182 TI - Assessment of infant formula quality and composition using Vis-NIR, MIR and Raman process analytical technologies. AB - In this study, visible and near-infrared (Vis-NIR), mid-infrared (MIR) and Raman process analytical technologies were investigated for assessment of infant formula quality and compositional parameters namely preheat temperature, storage temperature, storage time, fluorescence of advanced Maillard products and soluble tryptophan (FAST) index, soluble protein, fat and surface free fat (SFF) content. PLS-DA models developed using spectral data with appropriate data pre-treatment and significant variables selected using Martens' uncertainty test had good accuracy for the discrimination of preheat temperature (92.3-100%) and storage temperature (91.7-100%). The best PLS regression models developed yielded values for the ratio of prediction error to deviation (RPD) of 3.6-6.1, 2.1-2.7, 1.7 2.9, 1.6-2.6 and 2.5-3.0 for storage time, FAST index, soluble protein, fat and SFF content prediction respectively. Vis-NIR, MIR and Raman were demonstrated to be potential PAT tools for process control and quality assurance applications in infant formula and dairy ingredient manufacture. PMID- 29567183 TI - Simultaneous determination of isoproterenol, acetaminophen, folic acid, propranolol and caffeine using a sensor platform based on carbon black, graphene oxide, copper nanoparticles and PEDOT:PSS. AB - We explored the use of carbon black (CB), graphene oxide (GO), copper nanoparticles (CuNPs) and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) as electrode materials for the simultaneous determination of isoproterenol, acetaminophen, folic acid, propranolol and caffeine. The designed nanostructured surface was widely characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), contact angle measurements and electrochemistry. From electrochemical characterization assays carried out towards the potassium ferricyanide redox probe, fast electron transfer kinetics and a considerably higher electroactive surface area were observed for the modified electrodic surface based on CB, GO, CuNPs and PEDOT:PSS film. Using square-wave voltammetry (SWV), well defined and resolved anodic peaks were detected for isoproterenol, acetaminophen, folic acid, propranolol and caffeine, with peak-to-peak potential separation not less than 170 mV. Then, the SWV technique was explored for the simultaneous determination of quinary mixtures of these analytes, resulting in analytical curves with linear ranges and limits of detection at micromolar concentration levels. The practical viability of the proposed voltammetric sensor was illustrated in the analysis of human body fluid samples. The proposed sensor showed good repeatability and a successful application using urine and serum matrices, with recoveries close to 100%. PMID- 29567184 TI - Dual detection for non-aqueous capillary electrophoresis combining contactless conductivity detection and mass spectrometry. AB - Coupling of two detectors is a powerful tool to enhance the overall analytical performance generating complementary information and overcoming the limitations of the single detectors. In this work, capacitively coupled contactless conductivity detection (C4D) and electrospray ionization mass spectrometry (ESI MS) were coupled in conjunction with non-aqueous capillary electrophoresis (NACE). Non-aqueous electrolytes are highly compatible with ESI due to their volatility. Moreover, they exhibit low background conductivity, which is essential for the detection with C4D. A NACE-C4D-MS method was developed using an acetonitrile buffer containing 2 M HAc and 4 mM NH4Ac as background electrolyte. The influence of the inner diameter of the separation capillary on the C4D was studied and taken into account. A capillary with 50 um inner diameter was found to be best suited. The complementarity of the two detectors was shown by determining a sample mixture containing choline, thiamine, nitrate, and chloride as well as bromide and acetylcholine as internal standards. The C4D was the detector of choice for the inorganic ions, which were not detectable with the MS whereas the MS had much lower limits of detections for the organic biomolecules. The method was applied on an extract of a food supplement containing the model analytes.

AB - In this paper, a test strip-based sensor was developed for thiacloprid quantitative detection based on PDA molecularly imprinted polymer (MIP) and nitrogen-doped graphene quantum dots (N-GQDs). Thiacloprid is a new type of nicotine insecticide, which can block the normal neurotransmitter delivery process in insects. In the sensing system, N-GQDs were immersed into filter paper at first. Then, dopamine (DA) with thiacloprid can be self-polymerized on test strip surface to form the uniform PDA film. After removed thiacloprid template, the established poly dopamine (PDA) MIP can selectively recognize thiacloprid. As a result, captured thiacloprid can enhance the fluorescence intensity of N-GQDs into the test strip. As a result, the fluorescence intensity of N-GQDs can be linearly related within a certain range of thiacloprid concentration. Under the optimum conditions, the proposed sensor for thiacloprid detection exhibited a linear ranging from 0.1 mg/L to 10 mg/L with a low detection limit of 0.03 mg/L. The N-GQDs based test strip-based sensor for thiaclopridis reported for the first time. The sensing system has high selectivity to thiacloprid and provides new opportunities in the pesticide detection.

AB - Channel-like grooves are formed on the surface of frozen aqueous sucrose. They are filled with a freeze concentrated solution (FCS) and act as an efficient size tunable separation field for micro and nanoparticles. The width of the channel can be easily varied by changing the temperature. Because the channel width decreases with decreasing temperature, particles become immobilized due to physical interference from the ice wall when the temperature reaches a threshold point specific to the particle size. Surface modification of particles can add a factor of chemical interaction between the particles and ice walls. In this study, anti-freeze proteins (AFPs) are anchored on 1um-polystyrene (PS) particles, and their behavior in the surface grooves on the ice is studied. The threshold temperature is an effective criterion for evaluating chemical interactions between particles and ice walls. The AFP binding on 1um PS particles lowers the threshold temperature by 2.5 degrees C, indicating interactions between AFPs on the PS particles and the ice wall. Because the AFPs studied here show selectivity towards the prism plane, it is critical that the prism plane of the ice crystal is in contact with the FCS in the surface grooves.

AB - Early diagnosis is pivotal in subsequent prognosis and treatment of cancer. Herein, folic acid-conjugated carbon dots (FA-CDs) as a fluorescent nanoprobe were fabricated for identifying cancer cells visually. Green luminescent carbon dots (CDs) from active dry yeast (ADY) were readily prepared in scale-up to reach macroscopic production with a high yield of ~50% via a facile and rapid microwave approach. The as-prepared CDs were further combined with folic acid (FA) by covalent bonding to fabricate the FA-CDs for identification of cancer cells over expressing folate receptor (FR). Experimental outcomes demonstrated that the resultant FA-CDs noninvasively entered into cancer cells via receptor-mediated endocytosis and could differentiate FR-positive HepG2 cells from a cell mixture by fluorescence imaging, which suggests a promising prospect of the FA-CDs as an efficient probe for cancer diagnosis and succeeding personalized therapy.

AB - A method based on ion-pair reversed phase high performance liquid chromatography (HPLC) hyphenated with inductively coupled plasma mass spectrometry (ICP-MS) was developed for arsenic speciation in extract of tree moss. Under the optimal conditions, the limit of detection of eight arsenic species including arsenite (AsIII), arsenate (AsV), monomethylarsonic acid (MMA), dimethylarsonic acid (DMA), trimethylarsinoxide (TMAO), tetramethylarsonium (Tetra), arsenocholine (AsC) and arsenobetaine (AsB) is between 0.04 and 0.07 ng/mL, with a linear range of 0.2 - 500 ng/mL. Three unknown arsenic species (Unk1, Unk2 and Unk3) and six specific arsenic species (AsIII, AsV, DMA, TMAO, Tetra and AsB) were detected in the extract of tree moss. Unk3 was identified as a kind of arsenosugars (2,3 dihydroxypropyl-5-deoxy-5(dimethylarsenoso)furanoside, arsenosugar X) by electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-qTOF MS). PMID- 29567189 TI - Fast blood plasma separation device for point-of-care applications. AB - In this work, a simple device for extremely fast separation of blood plasma from diluted whole blood was developed. The device accommodates an asymmetric polysulfone membrane/supporting membrane sandwich that allows collection of 10 uL blood plasma into a narrow glass capillary in less than 10 s. The composition of diluent solution was optimized in order to achieve maximum recoveries for selected metabolites of alcohol intoxication. 5% solution of [tris(hydroxymethyl)methylamino] propanesulfonic acid provided recoveries of formate, oxalate and glycolate close to 100% and only moderate erythrocyte lysis. Both charged and uncharged compounds from the whole blood samples can be analyzed in the separated blood plasma by capillary electrophoresis with contactless conductometric detection and spectrophotometry, respectively. The developed device might find wide application in on-site testing and point-of-care analysis, when only microliter volumes of whole blood are available. PMID- 29567190 TI - Nitrogen and phosphorus dual-doped carbon dots as a label-free sensor for Curcumin determination in real sample and cellular imaging. AB - A nitrogen and phosphorus dual-doped carbon dots (NP-Cdots) was fastly synthesized with glucose as the carbon source, 1,2-ethylenediamine as N-dopant and concentrated phosphoric acid as P-dopant. The as-synthesized NP-Cdots was utilized as a label-free sensor for determination of Curcumin (Cur). The proposed NP-Cdots-based fluorescence sensor was applied for sensitive detection of Cur in aqueous solution, achieving a linear range of 0.5-20 umol/L and a detection limit of 58 nmol/L (21.37 ng/mL). The common amino acids and other drugs do not interfere with the detection of Cur, providing good selectivity. The constructed sensor was successfully applied to the determination of Cur in drinking water and the food samples with satisfactory results and the RSDs and recoveries were 0.08 5.39% and 95.2-105.2%, respectively. More importantly, the as-prepared NP-Cdots was used as effective fluorescent agent for cellular imaging without noticeable cytotoxicity. The proposed sensor is simple and practical, illustrating that the potential application of NP-Cdots for biosensing, food monitoring and cellular labeling and imaging. PMID- 29567191 TI - A review of flow analysis methods for determination of radionuclides in nuclear wastes and nuclear reactor coolants. AB - The safety and security of nuclear power plant operations depend on the application of the most appropriate techniques and methods of chemical analysis, where modern flow analysis methods prevail. Nevertheless, the current status of the development of these methods is more limited than it might be expected based on their genuine advantages. The main aim of this paper is to review the automated flow analysis procedures developed with various detection methods for the nuclear energy industry. The flow analysis methods for the determination of radionuclides, that have been reported to date, are primarily focused on their environmental applications. The benefits of the application of flow methods in both monitoring of the nuclear wastes and process analysis of the primary circuit coolants of light water nuclear reactors will also be discussed. The application of either continuous flow methods (CFA) or injection methods (FIA, SIA) of the flow analysis with the beta-radiometric detection shortens the analysis time and improves the precision of determination due to mechanization of certain time consuming operations of the sample processing. Compared to the radiometric detection, the mass spectrometry (MS) detection enables one to perform multicomponent analyses as well as the determination of transuranic isotopes with much better limits of detection. PMID- 29567192 TI - MOF based fluorescent assay of xanthine oxidase for rapid inhibitor screening with real-time kinetics monitoring. AB - The activity assay of xanthine oxidase (XO) is of great application value in clinical diagnosis because the abnormal level of this enzyme is related to a series of pathological states. In this work, a Zr based metal-organic framework (BTB-MOF) with stable photoluminescence in pure water and buffer solution was synthesized. The examination about the fluorescent responses of this material to xanthine and its oxidation product, uric acid, showed that, although both of them affected the emission of BTB-MOF in quenching form, the efficiencies presented much difference. Taking advantage of this feature, a fluorescent method was developed for the activity assay of XO, that is, BTB-MOF was added to the enzymatic oxidation system as a sensor to transduce the proceeding of the reaction real-timely to the signal of fluorescent intensity change. Our method can work under the interference of normal biologically related species, and precisely reflect XO activity in the range of 0.2-40 U L-1 (detection limit = 0.004 U L-1). With consecutive fluorescence intensity scan, this assay could be applied as a high speed screening method of XO inhibitors with the testing time of 1 min. This work shows the wide potential application of MOFs in enzyme analysis. PMID- 29567193 TI - Tube radial distribution chromatography system developed by combining commercially available HPLC system and open-tubular capillary tube as separation column. AB - Tube radial distribution chromatography based on tube radial distribution flow, or annular flow, in an open-tubular capillary has been reported, where the annular flow is created through phase separation multiphase flow. The chromatographic system requires some specific instruments and treatments for microfluidic flow in the capillary tube. In this study, we developed a new set-up for tube radial distribution chromatography by combining a commercially available HPLC system with an open-tubular capillary tube (with an inner diameter of 100 um) as a separation column instead of a conventional packed column. The analyte solution was injected with an injection valve (2 MUL volume) and a ternary solution of water/acetonitrile/ethyl acetate (3:8:2 vol ratio) was delivered as the eluent to the capillary tube at a flow rate of 8.6 MUL min-1. The chromatographic system, that is, the HPLC system equipped with the open-tubular capillary tube, could successfully separate the model analytes, 1-naphthol, 1 naphthalenesulfonic acid, and 2,6-naphthalenedisulfonic acid, with base-line separation. The inner and outer phases in the annular flow worked as the mobile and pseudo-stationary phases, respectively, in the tube radial distribution chromatography system. The experimentally obtained elution times of the analytes were compared with their corresponding theoretical values calculated using their capacity factors for the inner and outer phases and the linear flow velocities of the respective phases.

AB - The increasing awareness and public concern with hazard exposure to endocrine disrupting chemicals calls for methods capable to handle numerous samples in short analysis time. In this present study, a novel method combining air-assisted liquid-liquid microextraction and liquid chromatography coupled to mass spectrometry was developed and validated for the extraction, preconcentration, and determination of 7 bisphenols (bisphenol A, bisphenol S, bisphenol AP, bisphenol P, bisphenol F, bisphenol AF, bisphenol Z), 7 parabens (methyl-, ethyl , propyl-, butyl-, benzyl-paraben, methyl-protocatechuic acid, and ethyl protocatechuic acid), 5 benzophenones (benzophenone-1, benzophenone-2, benzophenone-3, benzophenone-8, and 4-hydroxybenzophenone), and two antimicrobials (triclosan and triclocarban) in human urine samples. Type and volume of solvent, extraction time (cycles), pH sample, ionic strength, agitation, and needle dimensions were evaluated. The matrix-matched calibration curves of all analytes were linear with correlation coefficients higher than 0.99 in the range level of 1.0-20.0 ng mL-1. The relative standard deviation, precision, at three concentrations (1.0, 10.0 and 20.0 ng mL-1) was lower than 15% with accuracy ranging from 90% to 114%. The biomonitoring capability of the new proposed method was confirmed with the analysis of 50 human urine samples randomly collected from Brazilian children. High urinary concentrations of several EDCs associated with usage of personal care products were found.

AB - As the pharmaceutical industry modernizes its manufacturing practices and incorporates more efficient processing approaches, it is important to reevaluate which process design elements affect product quality and the means to study these systems. The purpose of this work is to provide insight on a methodology to correlate the effect of raw material properties to equipment and process performance using both data-driven and semi-empirical models. In this work, lubricated blends of pharmaceutically-relevant materials were made using varying levels of magnesium stearate, ranging from 0.25 to 1.5%. Materials characterization (e.g., compressibility, permeability, density, particle size) was performed for all materials and blends. The blends were compressed using a two by three experimental design, varying tablet fill cam depth and tablet thickness, respectively. Tablet properties (e.g., weight, tensile strength, and thickness) were collected for all tablets. Using the collected tablet property results, models coefficients for the semi-empirical Kuentz and Leuenberger equation, which relates the tablet tensile strength to changes in porosity, were regressed. Empirical models were then developed to correlate the values of the Kuentz and Leuenberger equation coefficients to the blend material properties. The empirical models were then used in conjunction with the Kuentz and Leuenberger equation to evaluate the compression design and operational space, accounting for material properties. This proof of concept work aimed at developing correlations between raw material properties and unit operation models can aid process development, especially in design space characterization and robustness analysis. PMID- 29567196 TI - Comparison of melibiose and trehalose as stabilising excipients for spray-dried beta-galactosidase formulations. AB - Spray-dried protein formulations commonly require stabilising excipients to prevent protein degradation during processing and storage, and trehalose has been commonly used. The purpose of this work was to evaluate melibiose in spray-dried protein formulations in comparison to trehalose. The protein-activity-preserving efficacy, process behaviour and storage stability were studied. Spray drying of beta-galactosidase was carried out using different process temperature, drying air flow and feed liquid atomisation settings. Both melibiose and trehalose reduced protein activity loss during drying. A decrease in activities was observed when the process temperature exceeded a threshold temperature. During storage (30 days at 18% RH and 20 or 40 degrees C), the formulations dried below this threshold temperature showed no further activity loss, and the stabilising efficacy of the two disaccharides was equal. With higher process temperatures, the remaining protein activities after storage trended higher with melibiose formulations. All formulations remained amorphous. The powder yields of melibiose formulations were similar to trehalose. There was a difference in residual moisture contents, with melibiose formulations giving drier products. In conclusion, protein formulations with melibiose could be spray dried into amorphous powders that were physically stable, contained lower moisture contents and protected protein activity at least as well as trehalose formulations. PMID- 29567197 TI - Bone regeneration in osteoporosis by delivery BMP-2 and PRGF from tetronic alginate composite thermogel. AB - As the life expectancy of the world population increases, osteoporotic (OP) fracture risk increase. Therefore in the present study a novel injectable thermo responsive hydrogel loaded with microspheres of 17beta-estradiol, microspheres of bone morphogenetic protein-2 (BMP-2) and plasma rich in growth factors (PRGF) was applied locally to regenerate a calvaria critical bone defect in OP female rats. Three systems were characterized: Tetronic(r) 1307 (T-1307) reinforced with alginate (T-A), T-A with PRGF and T-A-PRGF with microspheres. The addition of the microspheres increased the viscosity but the temperature for the maximum viscosity did not change (22-24 degrees C). The drugs were released during 6 weeks in one fast phase (three days) followed by a long slow phase. In vivo evaluation was made in non-OP and OP rats treated with T-A, T-A with microspheres of 17beta-estradiol (T-A-betaE), T-A-betaE prepared with PRGF (T-A-PRGF-betaE), T A-betaE with microspheres of BMP-2 (T-A-betaE-BMP-2) and the combination of the three (T-A-PRGF-betaE-BMP). After 12 weeks, histological and histomorphometric analyzes showed a synergic effect due to the addition of BMP-2 to the T-A-betaE formulation. The PRGF did not increased the bone repair. The new bone filling the OP defect was less mineralized than in the non-OP groups. PMID- 29567198 TI - Lipid bilayer-coated mesoporous silica nanoparticles carrying bovine hemoglobin towards an erythrocyte mimic. AB - Hemoglobin (Hb)-loaded mesoporous silica nanoparticles (MSNs) coated with a lipid bilayer (LB-MSNs) were investigated as an erythrocyte mimic. MSNs with a large average pore size (10 nm) act as a rigid core and provide a protective environment for Hb encapsulated inside the pores. The colloidal stability of Hb loaded MSNs was enhanced upon the application of a lipid bilayer, through fusion of PEGylated liposomes onto the exterior surface of Hb-loaded MSNs. The morphology and mesostructure of the MSNs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and surface area analysis. The Hb loading capacity (mg/g) in MSNs was studied by thermogravimetric analysis (TGA). UV-Vis absorption spectroscopy revealed that Hb inside MSNs had an identical, but slightly broadened peak in the Soret region compared to free Hb. Furthermore the encapsulated Hb exhibits similar peroxidase-like activity in catalyzing the oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) with hydrogen peroxide. The introduction of a supported lipid bilayer (LB) demonstrated the potential to prevent premature Hb release (the burst release decreased from 25.50 +/- 0.33% to 6.73 +/- 0.83%) and increased the colloidal stability of the Hb-loaded MSNs (hydrodynamic diameter remained ~250 nm for at least one week). The in vivo systemic circulation and biodistribution of LB-MSNs were studied in optically transparent zebrafish embryos, revealing that LB-MSNs have the potential to act as an erythrocyte mimic in transfusion therapy. PMID- 29567199 TI - Are surgeons overdosing patients with lidocaine? PMID- 29567200 TI - The MEK5/ERK5 mitogen-activated protein kinase cascade is an effector pathway of bone-sustaining bisphosphonates that regulates osteogenic differentiation and mineralization. AB - Bisphosphonates play an important role in the treatment of metabolic bone diseases such as osteoporosis. In addition to their anti-resorptive activity by triggering osteoclast apoptosis, nitrogen-containing bisphosphonates (N-BP) may also influence osteogenic differentiation, which might rely on their capacity to inhibit the mevalonate pathway. In vascular endothelial cells inhibition of this pathway by cholesterol-lowering statins activates the MEK5/ERK5 mitogen-activated protein kinase cascade, which plays an important role in cellular differentiation, apoptosis or inflammatory processes. Here we evaluated whether N BP may also target the MEK5/ERK5 pathway and analysed the consequences of ERK5 activation on osteogenic differentiation. We show that N-BP dose-dependently activate ERK5 in primary human endothelial cells and osteoblasts. The mechanism likely involves farnesyl pyrophosphate synthase inhibition and subsequent functional inhibition of the small GTPase Cdc42 since siRNA-mediated knockdown of both genes could reproduce N-BP-induced ERK5 activation. ERK5 activation resulted in regulation of several bone-relevant genes and was required for calcification and osteogenic differentiation of bone marrow-derived mesenchymal stems cells as evident by the lack of alkaline phosphatase induction and alizarin-red S staining observed upon ERK5 knockdown or upon differentiation initiation in presence of a pharmacological ERK5 inhibitor. Our data provide evidence that N-BP activate the MEK5/ERK5 cascade and reveal an essential role of ERK5 in osteogenic differentiation and mineralization of skeletal precursors. PMID- 29567201 TI - In utero heat stress causes reduced testicular area at puberty, reduced total sperm production, and increased sperm abnormalities in boars. AB - In utero stress has been shown to negatively affect intact male rats and mice, though very little research has been conducted in boars. The objectives of the present studies were to determine the effects of in utero heat stress (IUHS) on postnatal development and the response to postnatal heat stress of boars. Ten boars were selected at weaning from litters subjected to IUHS or in utero thermoneutral (IUTN) during 30-60 days of gestation. The boars were evaluated for reproductive performance from birth through 57 weeks of age (WOA). Testicular area tended to be smaller for IUHS boars compared to IUTN boars at 24 WOA (P = 0.080). Libido did not differ for IUHS or IUTN (P = 0.818). Total sperm production was reduced in IUHS boars compared to IUTN boars (P <= 0.038). Semen volume and semen concentration did not differ (P >= 0.469 and P >= 0.664, respectively). Total motility and progressive motility did not differ for IUHS and IUTN boars (P >= 0.430 and P >= 0.652, respectively). In utero heat stressed boars had a greater incidence of sperm with tail abnormalities than IUTN (P <= 0.042). In utero heat stressed boars had a lower incidence of sperm with proximal droplets following mild, postnatal heat stress compared with IUTN (P = 0.005). In utero heat stress resulted in significant reductions in sperm production and increased sperm abnormalities in boars. The IUHS boars may be slightly more tolerant to postnatal heat stress, though more research is needed. PMID- 29567202 TI - Mating induces production of MMP2 in the llama oviduct: Analysis of MMP2 effect on semen. AB - Ovulation of South American Camelids is induced by mating. After copulation, sperm are stored into the oviduct to be released near ovulation time. To study whether copulation induces matrix metalloproteinase-2 (MMP2) secretion in the oviduct, the occurrence of MMP2 in oviductal tissue and oviductal fluid (OF) from 24 h post-mated was compared with non-mated llama females. There was an incremental increase of MMP2 in the oviductal epithelial cells, and MMP2 activity in OF after copulation. Additionally, MMP2 activator (MMP14), inducer (EMMPRIN) and inhibitor (TIMP2) were present in the oviductal epithelial cells of both non mated and post-mated females. A post-mating segment-specific regulation occurred because relative abundance of TIMP2 mRNA was greater in the utero tubal-junction which was accompanied with a reduced amount of MMP14 in the ampulla in comparison with the non-mated females. To examine the effect of MMP2 on semen liquefaction and sperm physiology, the effects of addition of recombinant human MMP2 was evaluated. The MMP2 had no effect on semen thread formation and seminal plasma protein profile. Sperm viability and plasma membrane function were not influenced by the enzyme treatment either. In summary, in llamas the oviductal microenvironment changes in response to stimuli induced by copulation, increasing the production and secretion of MMP2. PMID- 29567203 TI - Assessment of reproductive performance in F1 sows exposed to the porcine epidemic diarrhea virus at different periods of production stage on farms with different hygienic environments. AB - Porcine epidemic diarrhea (PED) occurred in Japan in 2013 after an interval of 7 years. The present study assessed individual productivity of sows exposed to PED virus at different periods of the production stage. The present study was performed at three commercial farms that had PED outbreak during the month of December 2013. Herd immunization was conducted for all gilts and sows. The production records were obtained for sows that were alive during the PED outbreak at each farm. The sows were categorized into six groups based on the period in which they were exposed to PED virus between days 0-30 (G1), 31-60 (G2), 61-90 (G3), or after 91 days of pregnancy (G4), during lactation (L), and after weaning (W). The control group was assigned based on the records before the period of PED outbreak (uninfected group). The number of sow's records obtained from farms A, B, and C were 1056, 1137, and 1035, respectively. Compared with the uninfected group, there was no reduction in the number of pigs born alive in the G1-G4 groups. Sows of the G4 and L groups, however, had 4-9 pigs fewer pigs weaned, and a 36%-77% greater pre-weaning mortality than the uninfected group (P < 0.05). There was no difference in farrowing rate and number of pigs born alive at subsequent parities among the sow groups. There were no interactions between sow groups and parity for sow productivity. PMID- 29567204 TI - Experts' perspectives on SwissDRG: Second class care for vulnerable patient groups? AB - On the 1st of January 2012, Switzerland introduced the diagnosis-related group hospital tariff structure (SwissDRG). It was recognised that healthcare provided to the most vulnerable patient groups would be a challenge for the new SwissDRG. Coincident with the implementation of SwissDRG, we explored hospital experts' perceptions of which patient groups are vulnerable under the SwissDRG system, what has changed for this group, as well as solutions to ensure adequate access to health care for them. We interviewed 43 experts from 40 Swiss hospitals. Participating experts named several vulnerable patient groups who share some common characteristics. These hospital experts were concerned about the patient groups that are not financially profitable and questioned the practicability of the current regulation. At the same time, they highlighted the complexity associated with caring for this group under the new SwissDRG and reported measures at the macro, meso, and micro levels to protect vulnerable patient groups from negative effects. To curb negative outcomes for vulnerable patient groups after the introduction of the SwissDRG, the Swiss legislation has introduced various instruments including the acute and transitional care (ATC) measures. We conclude that ATC measures do not produce the expected effect the legislators had hoped for. More health data is needed to identify situations where vulnerable patient groups are more susceptible to inadequate health care access in Switzerland. PMID- 29567205 TI - Innovative pharmaceutical pricing agreements in five European markets: A survey of stakeholder attitudes and experience. AB - BACKGROUND: Innovative pricing agreements for medicines have been used in European markets for more than 20 years, and offer an opportunity for payers and pharmaceutical companies to align on value, optimise speed to patients, and share risk. Developing successful agreements requires alignment between key stakeholders, yet there is a lack of summative data on how current innovative agreements are used in the real-world (e.g. the level of realised access to medicines, and rebates and discounts, which are often non-transparent). METHODS: This research used a web-based survey of payer stakeholders to determine what kinds of innovative agreements are currently used, anticipated future usage, attitudes, and drivers of adoption. Participants included national and regional payers (or former payers) and hospital-level decision makers. RESULTS: Sixty-six payers completed the survey. Respondents expected that the use of innovative pricing agreements will remain the same or increase in the future. Overall, they felt there is a positive attitude towards new schemes, and that innovative agreements are likely to be used when they reduce total costs or reduce uncertainty. CONCLUSIONS: Given payer expectations, pharmaceutical companies should continue to take a role in ensuring that they have sufficient capacity to support payers in the design and implementation of innovative pricing agreements.

AB - Four Cellular Retinol-binding Proteins (CRBP 1, 2, 3, 4) are encoded in the human genome. CRBP 1 and 2, sharing a 56% amino acid sequence identity, exhibit the highest binding affinities for retinol. Previous NMR studies provided some insights into the mechanism of retinol uptake, but details of such mechanism remain to be elucidated. Herein, the results of molecular dynamics simulations for the uptake of retinol by CRBP 1 and 2 are consistent with the presence of two different retinol entry points, both involving the 'cap region' (alpha-helices I and II and neighboring loops). We observed that a hydrophobic patch at the surface of the 'portal region' (alpha-helix II, CD and EF loops) of CRBP 1 attracts retinol, which accesses the binding cavity through an opening generated by the concerted movements of Arg58 and Phe57, present in the CD loop. In CRBP 2 a different distribution of the surface residues of the 'cap region' allows retinol to access the binding cavity by sinking in a hydrophobic matrix between the two alpha-helices. Polar interactions mainly affect retinol movements inside the beta-barrel cavities of both CRBPs. The interaction energy profiles are in agreement with the different behavior of the two protein systems. PMID- 29567209 TI - Heterotopic Ossification: The Keys to the Kingdom.

PMID- 29567210 TI - Myocarditis in Patients Treated With Immune Checkpoint Inhibitors. AB - BACKGROUND: Myocarditis is an uncommon, but potentially fatal, toxicity of immune checkpoint inhibitors (ICI). Myocarditis after ICI has not been well characterized. OBJECTIVES: The authors sought to understand the presentation and clinical course of ICI-associated myocarditis. METHODS: After observation of sporadic ICI-associated myocarditis cases, the authors created a multicenter registry with 8 sites. From November 2013 to July 2017, there were 35 patients with ICI-associated myocarditis, who were compared to a random sample of 105 ICI treated patients without myocarditis. Covariates of interest were extracted from medical records including the occurrence of major adverse cardiac events (MACE), defined as the composite of cardiovascular death, cardiogenic shock, cardiac arrest, and hemodynamically significant complete heart block. RESULTS: The prevalence of myocarditis was 1.14% with a median time of onset of 34 days after starting ICI (interquartile range: 21 to 75 days). Cases were 65 +/- 13 years of age, 29% were female, and 54% had no other immune-related side effects. Relative to controls, combination ICI (34% vs. 2%; p < 0.001) and diabetes (34% vs. 13%; p = 0.01) were more common in cases. Over 102 days (interquartile range: 62 to 214 days) of median follow-up, 16 (46%) developed MACE; 38% of MACE occurred with normal ejection fraction. There was a 4-fold increased risk of MACE with troponin T of >=1.5 ng/ml (hazard ratio: 4.0; 95% confidence interval: 1.5 to 10.9; p = 0.003). Steroids were administered in 89%, and lower steroids doses were associated with higher residual troponin and higher MACE rates. CONCLUSIONS: Myocarditis after ICI therapy may be more common than appreciated, occurs early after starting treatment, has a malignant course, and responds to higher steroid doses. PMID- 29567212 TI - Molecular dissection of the membrane aggregation mechanisms induced by monomeric annexin A2. AB - Annexins are a multigene family of proteins involved in aggregation and fusion processes of biological membranes. One of its best-known members is annexin A2 (or p36), capable of binding to acidic phospholipids in a calcium-dependent manner, as occurs with other members of the same family. In its heterotetrameric form, especially with protein S100A10 (p11), annexin A2 has been involved as a determinant factor in innumerable biological processes like tumor development or anticoagulation. However, the subcellular coexistence of different pools of the protein, in which the monomeric form of annexin A2 is growing in functional relevance, is to date poorly described. In this work we present an exhaustive structural and functional characterization of monomeric human annexin A2 by using different recombinant mutants. The important role of the amphipathic N-terminal alpha-helix in membrane binding and aggregation has been analyzed. We have also studied the potential implication of lateral "antiparallel" protein dimers in membrane aggregation. In contrast to what was previously suggested, formation of these dimers negatively regulate aggregation. We have also confirmed the essential role of three lysine residues located in the convex surface of the molecule in calcium-free and calcium-dependent membrane binding and aggregation. Finally, we propose models for annexin A2-mediated vesicle aggregation mechanisms. PMID- 29567214 TI - Volatile sulfur compounds in tropical fruits. AB - Global production and demand for tropical fruits continues to grow each year as consumers are enticed by the exotic flavors and potential health benefits that these fruits possess. Volatile sulfur compounds (VSCs) are often responsible for the juicy, fresh aroma of tropical fruits. This poses a challenge for analytical chemists to identify these compounds as most often VSCs are found at low concentrations in most tropical fruits. The aim of this review is to discuss the extraction methods, enrichment techniques, and instrumentation utilized to identify and quantify VSCs in natural products. This will be followed by a discussion of the VSCs reported in tropical and subtropical fruits, with particular attention to the odor and taste attributes of each compound. Finally, the biogenesis and enzymatic formation of specific VSCs in tropical fruits will be highlighted along with the contribution each possesses to the aroma of their respective fruit. PMID- 29567213 TI - Contribution of the exosome-associated form of secreted endoplasmic reticulum aminopeptidase 1 to exosome-mediated macrophage activation. AB - Macrophages secrete endoplasmic reticulum aminopeptidase 1 (ERAP1) in response to lipopolysaccharide (LPS) and interferon (IFN)-gamma to enhance their phagocytic and nitric oxide (NO) synthetic activities. In this study, we found that a subset of secreted ERAP1 bound to exosomes released from LPS/IFN-gamma-treated murine RAW264.7 macrophages compared to untreated cells. ERAP1-bound exosomes enhanced phagocytic and NO synthetic activities of macrophages more efficiently than free ERAP1 and exosomes derived from untreated cells. Deletion of the exon 10 coding sequence in ERAP1 gene resulted in loss of binding to exosomes. By comparing the activities of exosomes derived from wild-type and ERAP1 gene-deficient RAW264.7 cells, we observed that ERAP1 contributed to the exosome-dependent phagocytosis and NO synthesis of the cells. Upon stimulation of RAW264.7 cells with LPS/IFN gamma, TNF-alpha, IFN-gamma, and CCL3 were also associated with the released exosomes. Analyses of cytokine function revealed that while CCL3 in the exosomes was crucial to the phagocytic activity of RAW264.7 cells, TNF-alpha and IFN-gamma primarily contributed to the enhancement of NO synthesis. These results suggest that treatment with LPS/IFN-gamma alters the physicochemical properties of exosomes released from macrophages in order to facilitate association with ERAP1 and several cytokines/chemokines. This leads to exosome-mediated enhancement of macrophage functions. It is possible that packaging effector molecules into exosomes upon inflammatory stimuli, facilitates the exertion of effective pathophysiological functions on macrophages. Our data provide the first evidence that ERAP1 associated with exosomes plays important roles in inflammatory processes via activation of macrophages.

AB - In the present paper, we provide comprehensive information related to labeling claims and standards of identity of milk fat and spread products. By reviewing the standards and regulations for dairy and non-dairy fat products, Codex Alimentarius and several other countries have clearly specified these products and set the requirements for use of the product name to prevent misleading or confusing the consumers. Generally, for the milkfat products, the fat in the products should be exclusively from milk and/or the products obtained from milk. The milkfat contents of these products should be no less than 10%. Whereas, the blends or blended spreads are mixture of butter and vegetable oils with more than 3% of milkfat of the total fat content. The fat spreads are defined that any milkfat content must be no more than 3% of the total fat content. Although the specification of each fat product might be different, most countries still adopt the labeling system of Codex Alimentarius, including the use of the food names and the "reduced fat" claims. Each of the ingredients used in the food also need to be declared on the label. PMID- 29567216 TI - Regulatory analysis on the medical use of ephedrine-related products in Taiwan. AB - To prevent ephedrine-related products from being misused to produce amphetamine and/or its analogs, there's a need for more effective and achievable regulatory mechanisms for the health, police, investigational, prosecution and judiciary authorities in Taiwan. This review was conducted to evaluate the international and Taiwan's regulatory policies and management of medical ephedrine-related products through the corresponding information collected from international and Taiwan government agency authorities. The combat of illegal drugs should involve both supply and demand sides to be successful. Health authorities in Taiwan do not have the investigational power to manage the forbidden transformation, abusing and manufacture of the illegal drugs from ephedrine-related products. Take the judicial interventions in the United States and in Japan as the examples, the organizational cooperation in Taiwan can be one of the main key strategies to combat against illegal drugs from ephedrine-related products. It is necessary to integrate the judicial, police and health agencies to prevent the production of illegal drugs from the ephedrine-related products in Taiwan. The efforts and regulatory control measures should be integrated to speed up the collaboration between different government authorities. It might be achieved through reorganization involving Taiwan Food and Drug Administration. PMID- 29567217 TI - Bioactive polyphenols in kinkeliba tea (Combretum micranthum) and their glucose lowering activities. AB - Herbal tea kinkeliba prepared from the leaves of Combretum micranthum has been widely consumed in West African countries for its flavor, nutritional and medicinal properties. Under bio-guided screening, the kinkeliba leaves were chemically investigated using various chromatographic and spectrometric methods that led to the identification of thirteen different flavonoid compounds. Further biological tests illustrated that the identified compounds may have synergistic effects to decrease the expression of phosphoenolpyruvate carboxykinase (PEPCK) mRNA and glucose production in an H4IIE hepatoma cell line, indicating its potential use for insulin-resistant diabetes treatment. Further in vivo study on C57BL/6J mice indicates that kinkeliba can lower plasma glucose levels in a dose dependent manner without significant weight loss and toxicity. The ethyl acetate extract in rich of flavonoids could also increase the glucose tolerance (GT) after seven weeks' administrations. Both in vitro and in vivo experiments support a potential new application of kinkeliba leaves as an anti-diabetes agent. PMID- 29567218 TI - Characterization of key aroma-active compounds in lychee (Litchi chinensis Sonn.). AB - Volatile compounds in 'Sweetheart' lychee were examined using gas chromatography olfactometry/mass spectrometry (GC-O/MS). Solvent assisted flavor evaporation (SAFE) technique was used to identify the aroma-active compounds in lychee. Further characterization of the most important odorants in 'Sweetheart' lychee was achieved using aroma extract dilution analysis (AEDA). Thirty-one key aroma active odorants were identified in the flavor dilution (FD) factor range of 2 1024. Methional (cooked potato) and geraniol (sweet, floral) exhibited the highest FD factors of 1024 and 512, respectively, these were followed by furaneol (sweet, caramel), nerol (floral, sweet), dimethyl trisulfide (DMTS) (preserved vegetable, sulfury), linalool (floral), (E,Z)-2,6 nonadienal (cucumber) and nerolidol (metalic, sesame oil). Furthermore, the flavor profile of 'Sweetheart' lychee was described by sensory analysis. Floral, tropical fruit, peach/apricot and honey were scored with relatively high scores for each aroma attribute. The sweetness rating was the highest score among all the attributes. PMID- 29567219 TI - A simple and robust quantitative analysis of retinol and retinyl palmitate using a liquid chromatographic isocratic method. AB - Vitamin A is a vital nutritional substances that regulates biological activities including development, but is also associated with disease onset. The extent of vitamin A intake influences the retinoid content in the liver, the most important organ for the storage of vitamin A. Measurement of endogenous retinoid in biological samples is important to understand retinoid homeostasis. Here we present a reliable, highly sensitive, and robust method for the quantification of retinol and retinyl palmitate using a reverse-phase HPLC/UV isocratic method. We determined the impact of chronic dietary vitamin A on retinoid levels in livers of mice fed an AIN-93G semi-purified diet (4 IU/g) compared with an excess vitamin A diet (1000 IU/g) over a period from birth to 10 weeks of age. Coefficients of variation for intra-assays for both retinoids were less than 5%, suggesting a higher reproducibility than any other HPLC/UV gradient method. Limits of detection and quantification for retinol were 0.08 pmol, and 0.27 pmol, respectively, which are remarkably higher than previous results. Supplementation with higher doses of vitamin A over the study period significantly increased liver retinol and retinyl palmitate concentrations in adult mice. The assays described here provide a sensitive and rigorous quantification of endogenous retinol and retinyl palmitate, which can be used to help determine retinoid homeostasis in disease states, such as toxic hepatitis and liver cancer. PMID- 29567220 TI - Effects of electrode gap and electric current on chlorine generation of electrolyzed deep ocean water. AB - Electrolyzed water is a sustainable disinfectant, which can comply with food safety regulations and is environmental friendly. A two-factor central composite design was adopted for studying the effects of electrode gap and electric current on chlorine generation efficiency of electrolyzed deep ocean water. Deep ocean water was electrolyzed in a glass electrolyzing cell equipped with platinum plated titanium anode and cathode in a constant-current operation mode. Results showed that current density, chlorine concentration, and electrolyte temperature increased with electric current, while electric efficiency decreased with electric current and electrode gap. An electrode gap of less than 11.7 mm, and a low electric current appeared to be a more energy efficient design and operation condition for the electrolysis system. PMID- 29567221 TI - Systematic study on active compounds as antibacterial and antibiofilm agent in aging onions. AB - Quantitative investigation and systematic studies of quercetin, total phenolics, flavonoids, antioxidants, antibacterial and antibiofilm or antibiofouling properties of methanolic extracts of onions obtained from six different varieties have been carried out to explore their relative merits in terms of biological activities of fresh and aging onions. Total phenolic content in the extracts was examined spectrophotometrically using Folin-Ciocalteau's phenol reagent and total antioxidant activity was studied by FRAP and DPPH methods. In vitro antibacterial activity of the extracts was investigated on Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus and Bacillus cereus) respectively, by using a modified Kirby-Bauer disc diffusion method. Antibiofilm activity was tested by crystal violet assay. The best results against biofilm formation were observed for the extracts obtained from onions stored for three months. The total phenolic and antioxidant content found to be increased upon aging in all the six varieties; red skinned onion (Happyhong) showed the highest level of total phenolics (5110.07 +/- 196.56 MUg GAEg-1 FW) and total flavonoids (2254.00 +/- 154.82 MUg QEg-1 FW) after three months. The results showed that in all the varieties, quercetin content as well as biological activity increases with aging in the stored onions compared with the fresh ones. PMID- 29567222 TI - Thyme essential oils from Spain: Aromatic profile ascertained by GC-MS, and their antioxidant, anti-lipoxygenase and antimicrobial activities. AB - Six samples of red thyme (Thymus zygis) and two samples of winter thyme (Thymus hyemalis) essential oils (EOs) were obtained from plants cultivated in south eastern Spain and extracted by steam distillation. Analysis by gas chromatography coupled with mass spectrometry detection provided the relative (%) and absolute (mM) concentrations. Thymol (30-54%), p-cymene (14-27%) and gamma-terpinene (8 28%) were the most abundant components of T. zygis EO, while 1,8-Cineole (3-37%), p-cymene (1-29%), linalool (8-13%) and thymol (0-19%) were the most abundant components in the case of T. hyemalis EO. Enantioselective gas chromatography identified (-)-linalool, (-)-borneol and (+)-limonene as the main enantiomers. Several methods to evaluate antioxidant capacities were applied to the EOs, concluding that their activities were mainly due to thymol and linalool. The inhibition of lipoxygenase activity, mainly due to thymol, p-cymene and linalool, suggested their possible use as anti-inflammatories. The high antibacterial and antifungal activities determined for the EOs means that they can be used as natural preservatives. The results support the potential use of Thymus sp. EOs as natural food, cosmetic and pharmaceutical ingredients. PMID- 29567223 TI - Modifications of Atlantic salmon by-product oil for obtaining different omega-3 polyunsaturated fatty acids concentrates: An approach to comparative analysis. AB - Omega-3 polyunsaturated fatty acids (omega-3 PUFAs) rich 2-monoacylglycerols (2 MAG), omega-3 polyunsaturated free fatty acids (omega-3 PUFFAs) concentrate, and PUFA enriched acylglycerols were prepared from salmon frame bone oil (SFBO) by enzymatic alcoholysis, urea complexation, and enzymatic esterification, respectively. The yields of 2-MAG, omega-3 PUFFAs concentrate, and PUFA enriched acylglycerols were 40.25, 16.52, and 15.65%, respectively. omega-3 PUFFAs concentrate and PUFA enriched acylglycerols showed darker red color than SFBO and 2-MAG due to aggregation of astaxanthin pigment in omega-3 PUFFAs concentrate during urea complexation. The viscosity and specific gravity of SFBO and PUFA enriched acylglycerols showed similar values whereas 2-MAG and omega-3 PUFFAs showed significantly (p < 0.05) lower values. Stability parameters like acid value, peroxide value, free fatty acid value, and p-anisidine value of SFBO and omega-3 PUFAs concentrates were within acceptable limits except extreme high acid value and free fatty acid value of omega-3 PUFFAs concentrate. Thermogravimetric analysis showed similar and higher thermal stability of SFBO and PUFA enriched acylglycerols than 2-MAG and omega-3 PUFFAs concentrate. The omega-3 PUFAs content in 2-MAG, omega-3 PUFFAs concentrate, and PUFA enriched acylglycerols was increased to 20.81, 52.96, and 51.74% respectively from 13.54% in SFBO. omega-3 PUFFAs concentrate and PUFA enriched acylglycerols showed higher DPPH and ABTS radical scavenging activity than SFBO and 2-MAG. The results obtained from this study suggest the production of PUFA enriched acylglycerols rich in omega-3 PUFAs supplements from fish oil for human and pet animals. PMID- 29567224 TI - Cytotoxic protobassic acid saponins from the kernels of Palaquium formosanum. AB - Bioassay guided fractionation and separation of the EtOH extract of the kernels of Palaquium formosanum against PC-3 cells via Sephadex LH-20 and reverse phase C 18 columns led to the isolation of 13 protobassic saponins. One of these saponins is new and was characterized as 3'''-O-rhamnopyranosyl-arganin C, a bisdesmoside of 16alpha-hydroxyprotobassic acid at the C-3 and C-28 positions. The structures of these compounds were determined on the basis of 1D NMR (1H, 13C), 2D NMR (1H 1H COSY, HSQC, HMBC, and NOESY), and selectively excited 1D TOCSY spectroscopic analyses and MS data, and comparison with literature data. Bioassay of these compounds and five additional compounds, isolated from Planchonella obovata leaf, against PC-3 prostate cancer cells indicated arganin C to be the most potent one with the IC50 value of 13.8 MUM. Some structure and activity relationships were also drawn. PMID- 29567225 TI - Analysis of veterinary drug residue monitoring results for commercial livestock products in Taiwan between 2011 and 2015. AB - Antibiotics have been widely used in the treatment of livestock diseases. However, the emergence of issues related to drug resistance prompted governments to enact a series of laws regulating the use of antibiotics in livestock. Following control of the problem of drug resistant bacteria, public attention has shifted to the recurring incidence of human health and safety issues caused by residual veterinary drugs in livestock products. To guarantee the safety and hygiene of meat, milk, and eggs from food-producing animals, governments and relevant agencies established laws and regulations for the use of veterinary drugs. It is, therefore, necessary to monitor the content of residual drugs in livestock products at regular intervals to assess whether the regulations have resulted in the effective management of food product safety, and to prevent and manage sudden problems related to this issue. A 2011-2015 livestock product post marketing monitoring program launched by the Taiwan Food and Drug Administration (TFDA) inspected 1487 livestock products. Over the past 5 years, there were 34 samples identified that did not conform to the regulations; these samples included residue drugs such as beta-agonists, chloramphenicols, beta-lactam antibiotics, sulfa drugs, enrofloxacin, and lincomycin. Inspections of commercial livestock products with the consistent cooperation of agricultural authorities did not detect the drugs that were banned by the government, whereas the detection of other drugs decreased annually with an increase in the post-market monitoring sample size. In the future, the TFDA will continue to monitor the status of residual veterinary drugs in commercial livestock products, adjust the sampling of food products annually according to monitoring results, and closely cooperate with agricultural authorities on source management. PMID- 29567226 TI - Use of UHPLC-TripleQ with synthetic standards to profile anti-inflammatory hydroxycinnamic acid amides in root barks and leaves of Lycium barbarum. AB - Hydroxycinnamic acid amides (HCAA) are the secondary metabolites ubiquitously exist in flowering plants, formed by condensation between hydroxycinnamates and mono or polyamines. HCAA species not only serve multiple functions in plant growth and development, but also exert significant positive effects on human health. In this study, we combined organic synthesis and UPHLC-TripleQ-MS/MS specifically targeting at HCAA species. The method was fully validated with respect to specificity, linearity, intra- and inter-day precision and accuracy, limit of detection (LOD), limit of quantification (LOQ), recovery, and reproducibility. We applied this method to identify and quantify HCAAs from the root barks and leaves of Lycium barbarum. HCAA species were reported in leaves for the first time, and 10 new HCAA species were further identified in root barks in addition to the ones reported in the literature. We also examine anti inflammatory properties of identified HCAAs species. Seven HCAA compounds had a potent NO inhibitory effect with IC50 as low as 2.381 MUM (trans-N-caffeoyl phenethylamine). Our developed method largely improved analytical sensitivity of HCAAs species that potentially contributes to plant metabolomics studies. PMID- 29567227 TI - Employing natural reagents from turmeric and lime for acetic acid determination in vinegar sample. AB - A simple, rapid and environmentally friendly sequential injection analysis system employing natural extract reagents was developed for the determination of acetic acid following an acid-base reaction in the presence of an indicator. Powdered lime and turmeric were utilized as the natural base and indicator, respectively. Mixing lime and turmeric produced an orange to reddish-brown color solution which absorbed the maximum wavelength at 455 nm, with absorbance decreasing with increasing acetic acid concentration. Influential parameters including lime and turmeric concentrations, reagent and sample aspirated volumes, mixing coil length and dispensing flow rate were investigated and optimized. A standard calibration graph was plotted for 0-5.0 mmol/L acetic acid with r2 = 0.9925. Relative standard deviations (RSD) at 2.0 and 4.0 mmol/L acetic acid were less than 3% (n = 7), with limit of detection (LOD) and limit of quantification (LOQ) at 0.12 and 0.24 mmol/L, respectively. The method was successfully applied to assay acetic acid concentration in cooking vinegar samples. Results achieved were not significantly different from those obtained following a batchwise standard AOAC titration method. PMID- 29567228 TI - Antioxidant activity and calcium binding of isomeric hydroxybenzoates. AB - The association constant for calcium binding to hydroxybenzoates in aqueous 0.16 M NaCl at 25 degrees C was found electrochemically to have the value Kass = 280 mol L-1 with DeltaHo = -51 kJ mol-1, DeltaSo = -122 J mol-1 K-1 for the 2-isomer (salicylate), Kass = 7 mol L-1 with DeltaHo = -39 kJ mol-1, DeltaSo = -116 J mol 1 K-1 for the 3-isomer, and Kass = 8 mol L-1 with DeltaHo = -51 kJ mol-1, DeltaSo = -155 J mol-1 K-1 for the 4-isomer. The 3- and 4-isomers were found more efficient as antioxidants than the 2-isomer in decreasing oxygen consumption rate in a peroxidating methyl linoleate emulsion and less sensitive to presence of calcium. All isomers were found prooxidative for iron-catalyzed initiation of oxidation due to enhanced radical formation as shown by electron spin resonance spectroscopy. Calcium salicylate was found to have low solubility with a solubility product Ksp = 4.49.10-6 based on activity with DeltaHo = 67 kJ mol-1, DeltaSo = 123 J mol-1 K-1 for dissolution in water, when corrected for the strong complex formation. Calcium in food and beverages may thus lower antioxidant activity of plant phenols through complexation or by precipitation.

AB - Water-soluble sulfated polysaccharides extracted from Ulva intestinalis and fractionated using DEAE Sepharose fast flow column to identify their molecular properties and macrophage cells stimulating activities. Crude and fractions (F1 and F2) were formed of neutral sugars (58.7-74.7%), sulfates (6.2-24.5%), uronic acids (4.9-5.9%) and proteins (3.2-10.4%). Different levels of sugar constituents including rhamnose (30.1-39.1%), glucose (39.0-48.4%), galactose (0.0-15.8%), xylose (8.5-11.3) and arabinose (0.0-5.1%). The molecular weight (Mw) of crude and fractionated polysaccharides ranged from 87.1 * 103 to 194.1 * 103 (g/mol). Crude polysaccharides were not toxic to RAW264.7 cells and fractions induced cell proliferation. Fraction F1 stimulated RAW264.7 cells to release considerable amounts of nitric oxide, IL-1beta, TNF-alpha, IL-6, IL-10 and IL-12 cytokines. The main backbone of the most immunostimulating polysaccharide (F1) was consisted of mixed linkages of (1 -> 2)-linked rhamnose and (1 -> 2)-linked glucose residues. PMID- 29567230 TI - Relative content of gallic acid over 5-galloylquinic acid as an index for the baking intensity of oolong teas. AB - Phenolic compounds in a series of old oolong teas prepared by baking annually were monitored and compared. The results showed that the relative content of gallic acid over 5-galloylquinic acid was subsequently elevated during this preparatory process. To reveal the effect was mainly resulted from baking or aging, two sets of oolong teas were collected and examined; one set was generated from fresh oolong tea via continually daily baking and the other set was composed of aged oolong teas with no or light baking in the storage period. The relative content of gallic acid over 5-galloylquinic acid was observed to be subsequently elevated when oolong tea was continually baked at 90, 100, 110, and 120 degrees C for 8 h day after day. In contrast, the relative contents of gallic acid over 5 galloylquinic acid in aged oolong teas with no or light baking were found to be similar to or slightly higher than that in fresh oolong tea. The results suggest that the relative content of gallic acid over 5-galloylquinic acid seems to be a suitable index for the baking intensity of oolong tea in different preparations. PMID- 29567231 TI - Gallic acid inhibits bladder cancer cell proliferation and migration via regulating fatty acid synthase (FAS). AB - Bladder cancer is known as the world's ninth most prevalent cancer in 2012. New cytotoxic drugs have created considerable progress in the treatment. Gallic acid (GA) has been shown to inhibit carcinogenesis in animal models and various cancer cell lines. The aim of the present study was to evaluate the effect of GA on proliferation and migration inhibition of a bladder cancer cell line. The results showed that GA inhibited fatty acid synthase (FAS) activity and increased ER alpha level of TSGH-8301 bladder cancer cell. GA regulated the cell proliferation via the PI3K/AKT and MAPK/ERK pathway. Immunoprecipitation assay demonstrated that GA decreased Skp2 protein level and attenuated Skp2-p27 association. It was suggested that GA acted upstream of the proteasome to control p27 levels and ultimately inhibited G2/M phase transition. Further, transwell chambers assay showed that GA suppressed bladder cancer cell invasion and migration through p AKT/MMP-2 signaling pathway. The finding indicated that GA inhibited TSGH-8301 bladder cancer cell growth, invasion and migration through inhibition of fatty acid synthase. PMID- 29567233 TI - Modified QuEChERS method for 24 plant growth regulators in grapes using LC-MS/MS. AB - A multiresidue analytical method was developed for grapes for the following 24 plant growth regulators: 1-naphthylacetamide, 2,3,5-triiodobenzoic acid, 2,4,5-T, 2-naphthoxyacetic acid, 3-indolylacetic acid, 4-(3-indolyl)-butyric acid, 4 chlorophenoxyacetic acid, 4-nitrophenol, 6-benzylaminopurine, N6 isopentenyladenine, butralin, chlormequat chloride, chlorphonim-Cl, cloprop, forchlorfenuron, gibberellic acid 3, gibberellic acid 4, gibberellic acid 7, inabenfide, mepiquat chloride, paclobutrazol, prohydrojasmon, thidiazuron and uniconizole-P. The compounds were extracted from grape samples using an extraction method modified from the Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method. Liquid chromatography - tandem mass spectrometry was used for the detection and quantification of the compounds. Validation of the method was performed by using recovery studies at both intra-day and inter-day intervals, as well as by evaluation of the matrix effect, limit of quantification, trueness and precision. We used matrix-matched calibrations for the quantification of the compounds, which all resulted in determination coefficients (r2) higher than 0.995. The limit of quantification ranged from 0.1 to 5 ng/mL. Recovery studies using three spiking concentrations at varying levels showed recoveries of 70.2-112.6% and 67.5-101.8% at intra-day and inter-day intervals, respectively. Relative standard deviations were below 20% for the recovery studies. The extraction method were further validated by performing recovery study and matrix effect test in six different grape varieties from Taiwan and the United States and all resulted in comparable results. Application of the established method to 50 grape samples, resulted in the detection of chlormequat chloride and forchlorfenuron residues in the tested grapes. The results of the method validation and real sample analysis shows the extraction method is therefore suitable for routine monitoring of residue in grapes. PMID- 29567232 TI - Methodology for sample preparation and size measurement of commercial ZnO nanoparticles. AB - This study discusses the strategies on sample preparation to acquire images with sufficient quality for size characterization by scanning electron microscope (SEM) using two commercial ZnO nanoparticles of different surface properties as a demonstration. The central idea is that micrometer sized aggregates of ZnO in powdered forms need to firstly be broken down to nanosized particles through an appropriate process to generate nanoparticle dispersion before being deposited on a flat surface for SEM observation. Analytical tools such as contact angle, dynamic light scattering and zeta potential have been utilized to optimize the procedure for sample preparation and to check the quality of the results. Meanwhile, measurements of zeta potential values on flat surfaces also provide critical information and save lots of time and efforts in selection of suitable substrate for particles of different properties to be attracted and kept on the surface without further aggregation. This simple, low-cost methodology can be generally applied on size characterization of commercial ZnO nanoparticles with limited information from vendors.

AB - Rice husk extract, obtained using acid and alkali pretreatment extraction (AAPE), contains bioactive compounds and exhibits reducing abilities. Phenolic composition in rice husk extract was analyzed and the mechanism of silver nanoparticle (AgNP) biosynthesis by using AAPE rice husk extract was investigated in this study. Stable and spherically shaped AgNPs with a size of <15 nm were prepared under the following conditions: 0.001 M AgNO3, AAPE rice husk extract diluted 10 times, pH 10, and reacted at 25 degrees C for 60 min. Synergistic effects among phenolic acids contributed to the formation of AgNPs, with the acids acting as excellent reducing agents (owing to their abundant hydroxyl groups) and excellent dispersants (owing to their derived CO groups), which enhanced the NPs' stability. Caffeic acid (CA) was demonstrated to synthesize AgNPs independently and is suggested to be the most crucial compound for reducing Ag+ during the biosynthesis with rice husk extract. A possible mechanism and reaction process for the formation of AgNPs synthesized using CA in rice husk extracts is proposed. PMID- 29567235 TI - An investigation of the olive phenols activity as a natural medicine. AB - The natural antioxidants of olive oil have phenolic structure and their activities are related to the formation of stable derivatives. In this study, the single components of the phenolic fraction of olive oil (1,4-hydroquinone, Semiquinone and 1,4-benzoquinone) have been studied as theoretical by using DFT (Density functional Theory). The behaviors of phenolic compounds of olive against to the alkyl peroxy radicals were investigated. Our data show that 1,4 benzoquinone is the best electron transfer agent in primary metabolic processes to human life. The frontier orbital gap, namely HOMO (highest occupied molecular orbital)-LUMO (lowest unoccupied molecular orbital) gap is the smallest for 1,4 benzoquinone. Hence, it is more stable than the others in blood. The natural phenolic compound's mechanism of many plants can be explained by using DFT method without consuming time and money. In this study, we have indicated the behaviors of natural antioxidants of olive oil's single components phenolic structure in blood phase. PMID- 29567236 TI - Pt-MWCNT modified carbon electrode strip for rapid and quantitative detection of H2O2 in food. AB - A single-use screen-printed carbon electrode strip was designed and fabricated. Nanohybrids, prepared by deposition of platinum (Pt) nanoparticles on multi-wall carbon nanotube (MWCNT), was modified on the surface of screen-printed carbon electrode for the development of a fast, sensitive and cost-effective hydrogen peroxide (H2O2) detection amperometric sensor strip. With Pt-MWCNT nanohybrids surface modification, current generated in response to H2O2 by the screen-printed carbon electrode strip was enhanced 100 fold with an applied potential of 300 mV. Quality of as-prepared electrode strip was assured by the low coefficient of variation (CV) (<5%) of currents measured at 5 s. Three linear detection ranges with sensitivity of 75.2, 120.7, and 142.8 MUA mM-1 cm-2 were observed for H2O2 concentration in the range of 1-15 mM, 0.1-1 mM, and 10-100 MUM, respectively. The lowest H2O2 concentration could be measured by the as-prepared strip was 10 MUM. H2O2 levels in green tea infusion and pressed Tofu could be rapidly detected with results comparable to that measured by ferrous oxidation xylenol orange (FOX) assay and peroxidase colorimetric method.

AB - A mercury(II) ion-selective electrode with an ionic liquid (IL), 1-methyl-2 butylthioimidazolium bis(trifluoromethanesulphonyl)imide ([C1C4Sim]NTf2) as active material was constructed. Parameters affecting the performance of the electrodes such as the dosages of the IL and carbon nanotubes and the aqueous pH values were investigated. Experimental results indicated that the optimal composition of the electrode filling material was 47.6% [C1C4Sim]NTf2, 47.6% tetrabutylphosphonium bis(trifluoromethanesulphonyl)imide (TBPNTf2) and 4.8% carboxylic multi-walled carbon nanotubes (MWCNTs-COOH). Under the selected conditions, the proposed electrodes showed a good linear response in the concentration range of 10-10-10-5 mol L-1 and had a detection limit of 4.1 * 10 11 mol L-1. No great interference from common metal ions was found. The proposed electrodes were applied to determine Hg2+ in seafood samples; the results were comparable to those of the direct mercury analyzer.

AB - Fucose is one of important residues of recognition pattern for many immune cells. In this study, we characterized bioactive fucose-containing acidic polysaccharides from submerged fermentation of Agaricus blazei Murill. We obtained the polysaccharides through a cell-based activity-guided strategy, and used carbohydrate recognition monoclonal antibodies based Enzyme-Linked Immuno Sorbent Assay (ELISA) along with methylation and NMR analyses to investigate the structural characteristics of the polysaccharides. The polysaccharides had Mw of 3.5 * 105 Da. The major sugars were l-fucose, l-arabinose, d-galactose, d-xylose, and d-galacturonic acid in the molar ratio of 6.4, 15.5, 28.5, 14.7, and 25.0% with a small amount of d-glucose, d-mannose, l-rhamnose, and d-glucuronic acid. Results indicated that the bioactive polysaccharides consisted of a (1,4)-Galp and (1,4)-GalAp back bone; (1,2)-Xyl and (1,2)-Rha might also comprise backbone or constitute side chain; linkage (1,5)-Ara and terminal fucosyl residues were also involved in the polysaccharides. Regarding bioactivity, removal of the terminal l-fucosyl residues reduced the TNF-alpha cytokine stimulating activity of the polysaccharides in a RAW 264.7 macrophage cell-line test, whereas NF kappaB and TLR4 affected the polysaccharide-induced TNF-alpha production. PMID- 29567239 TI - HPTLC-FLD-SERS as a facile and reliable screening tool: Exemplarily shown with tyramine in cheese. AB - The serious cytotoxicity of tyramine attracted marked attention as it induced necrosis of human intestinal cells. This paper presented a novel and facile high performance thin-layer chromatography (HPTLC) method tailored for screening tyramine in cheese. Separation was performed on glass backed silica gel plates, using methanol/ethyl acetate/ammonia (6/4/1 v/v/v) as the mobile phase. Special efforts were focused on optimizing conditions (substrate preparation, laser wavelength, salt types and concentrations) of surface enhanced Raman spectroscopy (SERS) measurements directly on plates after derivatization, which enabled molecule-specific identification of targeted bands. In parallel, fluorescent densitometry (FLD) scanning at 380 0.995). Recoveries of this method estimated at three spiked concentrations of 100, 250 and 500 ng mL-1 in pig hair samples, were 79 82% for ractopamine and 77-96% for salbutamol. The corresponding inter-day and intra-day precisions expressed as relative standard deviation (RSD %) were 3.8 6.4% and 3.8-8.6%, respectively. The analytical time for one sample was 8 min. The detection limit of this method was 0.6 and 8.3 ng mL-1 for ractopamine and salbutamol, respectively. This developed method can be applied for monitoring the use of the beta-agonists salbutamol and ractopamine in swine feed incurred pig hair. PMID- 29567244 TI - Effects of vinegar-egg on growth inhibition, differentiation human leukemic U937 cells and its immunomodulatory activity. AB - Vinegar and eggs have rich nutrients. In this study, the mixed form of both derived products, vinegar-egg solution and its products (vinegar-egg concentrate and vinegar-egg condensate) were chosen for an assessment of their biological activity. To further our understanding regarding the anticancer and immunomodulatory effects of vinegar-egg, we investigated its effects on the proliferation and differentiation of U937 cells. Vinegar-egg was treated using spray drying, freeze drying and vacuum concentration and used to stimulate human mononuclear cells. The conditioned media obtained from these cultures by filtration were used to treat U937 cells. Three conditioned media inhibited U937 cell growth by 22.1-67.25% more effectively than PHA-treated control (22.53%). CD11b and CD14 expression on the treated U937 cells were 29.1-45.4% and 31.6 47.2%, respectively. High levels of cytokines IL-1beta, IFN-gamma and TNF-alpha were detected in the three conditioned media. Vinegar-egg stimulates human mononuclear cells to secrete cytokines, which inhibit the growth of U937 cells and induce their differentiation. PMID- 29567245 TI - Immunochemical assay with monoclonal antibodies for detection of staphylococcal enterotoxin H. AB - Staphylococcal enterotoxins cause food poisoning of various degrees of severity. For milk and meat products, there is a high probability of contamination with staphylococcal enterotoxin H (SEH). In this regard specific and sensitive methods are required to be developed for its detection and monitoring. In this work, the gene seh was expressed and a preparation of recombinant toxin was obtained. Using hybridoma technology, a panel of high-affinity monoclonal antibodies (mAbs) to SEH was produced. The antibodies were characterized and shown to have no cross reactivity towards the main staphylococcal enterotoxins (A, B, C1, D, E, G and I). Based on these mAbs, a method for specific and quantitative detection of SEH was developed in the format of sandwich enzyme immunoassay (linear range, 0.2-3 ng/ml). All the mAbs produced revealed SEH by immunoblotting. Immunochemical analysis of the culture fluids of staphylococcal isolates obtained from the milk of mastitis-infected cows by immunoblotting and sandwich enzyme immunoassay demonstrated the conformity of these methods. Using the developed method, the toxin was revealed in blood serum and liquid food products practically to 100%. From non-liquid foods, it was shown to be extracted to a maximum with a buffer of pH 4.0-4.5. PMID- 29567246 TI - Rapid screening of toxic glycoalkaloids and micronutrients in edible nightshades (Solanum spp.). AB - African indigenous vegetables (AIVs) because of their nutrient density have the unique potential to reduce micronutrient deficiencies in sub-Saharan Africa, yet some may also contain anti-nutritive compounds. Vegetable nightshades from Solanum americanum, Solanum nigrum, Solanum scabrum and Solanum villosum are among the major AIVs used as a leafy vegetables and consumed regularly in many countries in sub-Sahara Africa. These under-recognized food crops have not been subjected to extensive studies for their nutritional and antinutritive factors. In this study, 15 entries of the vegetable nightshades were field-grown and the leaves which are the consumed product of commerce chemically profiled by LC/ESI MS. Twenty-three flavones, eight saponins, and two glycoalkaloids along with a phenolic acid of chlorogenic acid were identified by MS and UV data. Anti nutrient glycoalkaloids were quantified as total aglycones after acidic hydrolysis using MS detection and found to be within safe-consumption thresholds by comparison with the glycoalkaloid level in the globally consumed Solanum member eggplants. Edible nightshades were also found to be sources of beta carotene, vitamin E and total polyphenols and exhibited high antioxidant activity. Results of this study support that consumption of vegetable nightshades are safe from the presence of glycoalkaloids and thus, can contribute to the reduction of micronutrient deficiency in sub-Sahara Africa. PMID- 29567247 TI - Antibacterial activity of propolins from Taiwanese green propolis. AB - Taiwanese green propolis is a prenylated flavonoid rich honeybee product and propolins isolated from Taiwanese green propolis exert a broad spectrum of biological activities, such as anti-cancer and anti-oxidant. However, the anti bacterial effects of Taiwanese green propolis or propolins are still poorly understood. In the current study, the antibacterial effects of Taiwanese green propolis and propolins were evaluated. Results show that the maximum dry matter yields of Taiwanese green propolis were observed in the 95% and 99.5% ethanol extracts compared to other extraction methods. Consistently, the highest concentration of propolins C, D, F and G from Taiwanese green propolis was obtained in 95% and 99.5% ethanol extracts. Propolins inhibited the growth of gram-positive bacterial strains (Staphylococcus aureus, Bacillus subtilis, Listeria monocytogenes and Paenibacillus larvae). The average minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of propolins from ethanol extracts were 20 MUg/ml. Among the propolins, propolin C had the highest antibacterial activity. Furthermore, Taiwanese green propolis also showed antibacterial activity against methicillin-resistant S. aureus (MRSA). In conclusion, these results demonstrate that Taiwanese green propolis and propolins have significant antibacterial activity, particularly against gram-positive bacterial strains. PMID- 29567248 TI - The integration of multi-platform MS-based metabolomics and multivariate analysis for the geographical origin discrimination of Oryza sativa L. AB - For the authentication of white rice from different geographical origins, the selection of outstanding discrimination markers is essential. In this study, 80 commercial white rice samples were collected from local markets of Korea and China and discriminated by mass spectrometry-based untargeted metabolomics approaches. Additionally, the potential markers that belong to sugars & sugar alcohols, fatty acids, and phospholipids were examined using several multivariate analyses to measure their discrimination efficiencies. Unsupervised analyses, including principal component analysis and k-means clustering demonstrated the potential of the geographical classification of white rice between Korea and China by fatty acids and phospholipids. In addition, the accuracy, goodness-of fit (R2), goodness-of-prediction (Q2), and permutation test p-value derived from phospholipid-based partial least squares-discriminant analysis were 1.000, 0.902, 0.870, and 0.001, respectively. Random Forests further consolidated the discrimination ability of phospholipids. Furthermore, an independent validation set containing 20 white rice samples also confirmed that phospholipids were the excellent discrimination markers for white rice between two countries. In conclusion, the proposed approach successfully highlighted phospholipids as the better discrimination markers than sugars & sugar alcohols and fatty acids in differentiating white rice between Korea and China. PMID- 29567249 TI - Mulberry Leaf Extracts prevent obesity-induced NAFLD with regulating adipocytokines, inflammation and oxidative stress. AB - Mulberry (Morus alba) leaf has been used in Chinese medicine as the remedy for hyperlipidemia and metabolic disorders. Recent report indicated Mulberry leaf extract (MLE) attenuated dyslipidemia and lipid accumulation in high fat diet (HFD)-fed mice. Non-alcoholic fatty liver (NAFLD) is generally considered as the liver component of metabolic syndrome. The hepatic lipid infiltration induces oxidative stress, and is associated with interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) which are regulated by the leptin and adiponectin. MLE could prevent obesity-related NAFLD via downregulating the lipogenesis enzymes while upregulating the lipolysis markers. Treatment of MLE, especially at 2%, enhanced the expression of superoxide dismutase (SOD) and clenched the oxidative stress of liver. MLE decreased the plasma level of leptin but increased adiponectin. The advantage of MLE is supposed mainly attributed to chlorogenic acid derivative. We suggest MLE, with promising outcome of research, could be nutraceutical to prevent obesity and related NAFLD. PMID- 29567250 TI - Simultaneous quantification of eight organic acid components in Artemisia capillaris Thunb (Yinchen) extract using high-performance liquid chromatography coupled with diode array detection and high-resolution mass spectrometry. AB - We aim to determine the chemical constituents of Yinchen extract and Yinchen herbs using high-performance liquid chromatography coupled with diode array detection and high-resolution mass spectrometry. The method was developed to analyze of eight organic acid components of Yinchen extract (including neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, 1,3 dicaffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid). The separation was conducted using an Agilent TC-C18 column with acetonitrile - 0.2% formic acid solution as the mobile phases under gradient elution. The analytical method was fully validated in terms of linearity, sensitivity, precision, repeatability as well as recovery, and subsequently the method was performed for the quantitative assessment of Yinchen extracts and Yinchen herbs. In addition, the changes of selected markers were studied when Yinchen herbs decocting in water and isomerization occurred between the chlorogenic acids. The proposed method enables both qualitative and quantitative analyses and could be developed as a new tool for the quality evaluation of Yinchen extract and Yinchen herbs. The changes of selected markers in water decoction process could give us some novel idea when studying the link between substances and drug efficacy. PMID- 29567251 TI - Effect of drying processes on prenylflavonoid content and antioxidant activity of Epimedium koreanum Nakai. AB - Epimedium koreanum Nakai is a famous Chinese herbal medicine for the treatment of impotence, osteoporosis, immune suppression and cardiovascular diseases. Drying is the most common and fundamental procedure in post-harvest processing of E. koreanum, which contributes to the variations of flavonoid content, especially prenylflavonoids, the bioactive components. In present study, effect of drying processes on flavonoid content and antioxidant activity were investigated. High performance liquid chromatography coupled with diode-array detection and electrospray ionization quadrupole time-of-flight tandem mass spectrometry methods were employed. Twenty seven compounds were identified and 11 of them, including eight prenylflavonoids and three other types of flavonoids, were further quantified. The antioxidant activity of E. koreanum was evaluated by the 2,2-diphenyl-1-picrylhydrazyl free radical scavenging method. The results showed that content of the eight prenylflavonoids exhibited significant variations after different drying processes, especially icariin and baohuoside I. The variation tendency of antioxidant activity was positively correlated with the content of total flavonoid, afzelin and icariin. PMID- 29567252 TI - General survey of Fructus Psoraleae from the different origins and chemical identification of the roasted from raw Fructus Psoraleae. AB - Fructus Psoraleae, a traditional Chinese medicine, is widely used for preventing and treating various diseases such as vitiligo, osteoporosis and psoriasis. Coumarin, such as psoralenoside, isopsoralenoside, psoralen and isopsoralen, are important compounds in Fructus Psoraleae. In our study, ultra performance liquid chromatography coupled with diode array detector was employed for an excellent method validation for simultaneous quantification of psoralenoside, isopsoralenoside, psoralen and isopsoralen, which was further applied in performing general survey of Fructus Psoraleae from the different origins and chemical identification of the roasted from raw Fructus Psoraleae in the light of illuminating the transformed rule of psoralenoside and isopsoralenoside. There is a reciprocal relationship between (iso)psoralenoside and (iso)psoralen, and the total content remains balance in Fructus Psoraleae from the different origins. In addition, we found that (iso)psoralenoside in the powder of the raw Fructus Psoraleae could be easily transformed into (iso)psoralen in methanol aqueous solution, especially above 50% water, rather than the roasted one. Thus, we proposed a hypothesis that transformation between (iso)psoralenoside and (iso)psoralen was hindered by inactivation of beta-glucosidase in the process of roasting Fructus Psoraleae, which was further verified by observing transformation of (iso)psoralenoside under the different conditions, such as temperature, pH and beta-glucosidase. Therefore, we developed a feasible method to distinguish the roasted from raw Fructus Psoraleae by observing conversion from (iso)psoralenoside to (iso)psoralen in 50% methanol aqueous solution. In summary, these results pave the way for elevating quality standard for Fructus Psoraleae and distinguishing the salt-processed from raw Fructus Psoraleae.

AB - A novel and sensitive assay for aflatoxin B1 (AFB1) detection has been developed by using bio-bar code assay (BCA). The method that relies on polyclonal antibodies encoded with DNA modified gold nanoparticle (NP) and monoclonal antibodies modified magnetic microparticle (MMP), and subsequent detection of amplified target in the form of bio-bar code using a fluorescent quantitative polymerase chain reaction (FQ-PCR) detection method. First, NP probes encoded with DNA that was unique to AFB1, MMP probes with monoclonal antibodies that bind AFB1 specifically were prepared. Then, the MMP-AFB1-NP sandwich compounds were acquired, dehybridization of the oligonucleotides on the nanoparticle surface allows the determination of the presence of AFB1 by identifying the oligonucleotide sequence released from the NP through FQ-PCR detection. The bio bar code techniques system for detecting AFB1 was established, and the sensitivity limit was about 10-8 ng/mL, comparable ELISA assays for detecting the same target, it showed that we can detect AFB1 at low attomolar levels with the bio-bar-code amplification approach. This is also the first demonstration of a bio-bar code type assay for the detection of AFB1 in Chinese herbs. PMID- 29567254 TI - Comprehensive two-dimensional APTES-decorated MCF7-cell membrane chromatographic system for characterizing potential anti-breast-cancer components from Yuanhu Baizhi herbal medicine pair. AB - Rhizoma corydalis and Radix Angelicae Dahurica (Yuanhu-Baizhi) herbal medicine pair has been used for thousands of years and has been reported to be potentially active in recent cancer therapy. But the exact active components or fractions remain unclear. In this study, a new comprehensive two-dimensional (2D) 3 aminopropyltriethoxysilane (APTES)-decorated MCF7-cell membrane chromatography (CMC)/capcell-C18 column/time-of-flight mass spectrometry system was established for screening potential active components and clarifying the active fraction of Yuanhu-Baizhi pair. APTES was modified on the surface of silica, which can provide an amino group to covalently link cell membrane fragments with the help of glutaraldehyde in order to improve the stability and column life span of the MCF7 CMC column. The comprehensive 2D MCF7-CMC system showed good separation and identification abilities. Our screen results showed that the retention components are mainly from the alkaloids in Yuanhu (12 compounds) and the coumarins (10 compounds) in Baizhi, revealing the active fractions of Yuanhu-Baizhi herbal medicine pair. Oxoglaucine, protopine, berberine, osthole, isopimpinellin and palmitic acid were selected as typical components to test the effects on cell proliferation and their IC50 were calculated as 38.17 MUM, 29.45 MUM, 45.42 MUM, 132.7 MUM, 156.8 MUM and 90.5 MUM respectively. Cell apoptosis assay showed that the drug efficacy was obtained mainly through inducing cell apoptosis. Furthermore, a synergistic assay results demonstrated that oxoglaucine (representative of alkaloids from Yuanhu) and isopimpinellin (representative of coumarins from Baizhi) showed significant synergistic efficacy with GFT, indicating that these components may act on other membrane receptors. The proposed 2D CMC system could also be equipped with other cells for further applications. Besides, the follow-up in-vitro experimental strategy using cell proliferation assay, cell apoptosis assay and synergistic assay proved to be a practical way to confirm the active fractions of herbal medicine. PMID- 29567255 TI - Stability-indicating spectrofluorimetric method with enhanced sensitivity for determination of vancomycin hydrochloride in pharmaceuticals and spiked human plasma: Application to degradation kinetics. AB - Based on investigating the relative fluorescence intensity of vancomycin hydrochloride (VCM) in methanol, a simple, highly sensitive, time-saving and specific spectrofluorimetric method was developed and validated. VCM fluorescence was measured at 335 nm when excited at 268 nm. Excellent linearity is obeyed in the concentration range 1-100 ng/mL with a detection limit of 5.94 pg/mL, a quantitation limit of 18.03 pg/mL and a very good correlation coefficient (r = 0.9999). Our method was applied to analyze VCM in pharmaceuticals as well as spiked human plasma. Moreover, VCM stability was studied when exposed to various degradation conditions such as oxidative, alkaline as well as acidic stress. Acidic and alkaline degradation kinetics of VCM was studied for the first time. The degradation follows pseudo-first-order kinetics. The apparent rate constants and half-life times were calculated. The Arrhenius equation was assessed and the activation energies of the degradation were also calculated. The developed method can be easily applied in quality control laboratories due to its sensitivity, specificity, simplicity and low cost. PMID- 29567256 TI - A validated capillary electrophoretic method for the determination of indacaterol and its application to a pharmaceutical preparation. AB - Indacaterol is a new inhaled ultra-long acting beta2-agonist. It has been recently approved in the European Union for the treatment of chronic obstructive pulmonary disease. This paper reports, for the first time, a method for the determination and validation of Indacaterol (IND) using an internal standard in capsules. Capillary electrophoretic separation was performed on an uncoated fused silica capillary (50 cm effective length, 75 MUm i.d.) and background electrolyte composed of 20 mmol L-1 of sodium tetraborate buffer, 15% (v/v) methanol (pH = 10.0) with the application of 20 kV of potential; 10 s at 5 * 103 N m-2 (50 mbar) of injection time; and wavelength of 200 nm and 25 degrees C of temperature. The linearity was evaluated in the range of 4.90 * 10-6 mol L-1 (2.50 MUg mL-1) and 3.94 * 10-5 mol L-1 (20.00 MUg mL-1), with R = 0.9993 for inter-day. LOD and LOQ values were 2.18 * 10-8 mol L-1 (0.011 MUg mL-1) and 7.25 * 10-8 mol L-1 (0.037 MUg mL-1) for inter-day, respectively. The precision values were 0.50-1.06% for intra-day and 2.12% for inter-day as RSD%. The accuracy was tested by the standard addition method with the recovery values being between 98.79 and 99.09 as percentages with RSD% interval of 0.01-0.80. The developed method was validated according to ICH guidelines. Indacaterol was successfully determined in Arcapta(r) capsule dosage form by the validated CE method with a relative error of 0.28%. The result was within the requirements of the USP 34-NF29. Therefore, the validated method may be used for the determination of Indacaterol in its capsules in quality control laboratories. PMID- 29567257 TI - Pharmacokinetics, bioavailability, tissue distribution and excretion of tangeretin in rat. AB - Tangeretin, 4',5,6,7,8-pentamethoxyflavone, is one of the major polymethoxyflavones (PMFs) existing in citrus fruits, particularly in the peels of sweet oranges and mandarins. Tangeretin has been reported to possess several beneficial bioactivities including anti-inflammatory, anti-proliferative and neuroprotective effects. To achieve a thorough understanding of the biological actions of tangeretin in vivo, our current study is designed to investigate the pharmacokinetics, bioavailability, distribution and excretion of tangeretin in rats. After oral administration of 50 mg/kg bw tangeretin to rats, the Cmax, Tmax and t1/2 were 0.87 +/- 0.33 MUg/mL, 340.00 +/- 48.99 min and 342.43 +/- 71.27 min, respectively. Based on the area under the curves (AUC) of oral and intravenous administration of tangeretin, calculated absolute oral bioavailability was 27.11%. During tissue distribution, maximum concentrations of tangeretin in the vital organs occurred at 4 or 8 h after oral administration. The highest accumulation of tangeretin was found in the kidney, lung and liver, followed by spleen and heart. In the gastrointestinal tract, maximum concentrations of tangeretin in the stomach and small intestine were found at 4 h, while in the cecum, colon and rectum, tangeretin reached the maximum concentrations at 12 h. Tangeretin excreted in the urine and feces was recovered within 48 h after oral administration, concentrations were only 0.0026% and 7.54%, respectively. These results suggest that tangeretin was mainly eliminated as metabolites. In conclusion, our study provides useful information regarding absorption, distribution, as well as excretion of tangeretin, which will provide a good base for studying the mechanism of its biological effects. PMID- 29567258 TI - A new strategy for choosing "Q-markers" via network pharmacology, application to the quality control of a Chinese medical preparation. AB - Due to its chemical complexity, proper quality control for a Chinese medical preparation (CMP) has been a great challenge. Choosing the appropriate quality markers (Q-markers) for quality control of CMP is an important work. Best of all, the chosen Q-markers are the main chemical compounds from the herbals as well as the active constituents of this CMP. Only in this way the established quality control system can really achieve the purpose of controlling the quality of CMP and ensuring the safely and effectively use of CMP. To achieve the purpose, network pharmacology combined with the contents of chemical compounds in the CMP has been used in this research. We took an anti-arrhythmic CMP, Shenxian-Shengmai oral liquid (SSOL), as an example. Firstly, UPLC-QTOF-MS/MS method was used to analyze the main components of SSOL. A total of 64 compounds were unambiguously or tentatively identified and 32 of them were further validated by reference compounds. Secondly, the network was constructed based on the identified compounds to predict the effective compounds related to cardiac arrhythmias. Based on the existing database and the operation method of topology, a method of double network analysis (DNAA) was proposed, from which 10 important targets in the pathway of arrhythmia were screened out, and 26 compounds had good antiarrhythmic activity. Based on the prediction results of network pharmacology along with the contents of the compounds in this CMP, ten representative compounds were chosen as the Q-markers for the quality control of SSOL. We find that five of these ten compounds, including danshensu, rosmarinic acid, salvianolic acid A, epimedin A and icariin, have antiarrhythmic activity. Then, the UPLC-DAD method was established as the control method for SSOL. PMID- 29567259 TI - In vitro and in vivo assessment of delivery of hydrophobic molecules and plasmid DNAs with PEO-PPO-PEO polymeric micelles on cornea. AB - The stability and bio-distribution of genes or drug complexes with poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO, Pluronic F-68) polymeric micelles (PM) are essential for an effective nanosized PM delivery system. We used Forster resonance energy transfer (FRET) pairs with PM and measured the FRET ratio to assess the stability of PM in vitro and in vivo on the cornea. The FRET ratio reached a plateau at 0.8 with 3% PM. Differential scanning calorimetry measurement confirmed the complex formation of FRET pairs with PM. Confocal imaging with the fluorophores fluorescein isothiocyanate isomer I (FITC) and rhodamine B base (RhB) also showed the occurrence of FRET pairs in vitro. The fluorophores were mixed with 3% PM solution or the FITC-labeled PEO-PPO-PEO polymers (FITC-P) were mixed with RhB-labeled plasmids (RhB-DNA). In addition, the in vitro corneal permeation of FRET pair complexes with PM reached a 0.8 FRET ratio. One hour after eye drop administration, FRET pairs colocalized in the cytoplasm, and surrounded and entered the nuclei of cells in the cornea, and the polymers were located in the corneal epithelial layers, as detected through anti PEG immunohistochemistry. Furthermore, fluorescence colocalization in the cytoplasm and cell nucleus of the corneal epithelium was confirmed in tissues where RhB or RhB-DNA complexed with FITC-P was found to accumulate. We demonstrate that at a concentration of 3%, PM can encapsulate FRET pairs or RhB DNA and retain their integrity within the cornea 1 h after administration, suggesting the feasibility and stability of PEO-PPO-PEO polymers as a vehicle for drug delivery.

AB - Copper ferrite-copper oxide (CuO-CuFe2O4) nanoparticles as a semiconductor composite with p-n junction were synthesized by co-precipitation reaction. Then, a novel CuO-CuFe2O4 carbon paste modified electrode was fabricated which displays an effectual electrocatalytic response to the oxidation of acetaminophen (AC) and codeine (CO). A linear range of 0.01-1.5 MUmol L-1 and 0.06-10.0 MUmol L-1 with the detection limits of 0.007 MUmol L-1 and 0.01 MUmol L-1 were achieved for AC and CO, respectively. The practical usage of the proposed sensor revealed reasonable results for quantification of AC and CO in biological fluids. PMID- 29567261 TI - Triple-component nanocomposite films prepared using a casting method: Its potential in drug delivery. AB - The purpose of this study was to fabricate a triple-component nanocomposite system consisting of chitosan, polyethylene glycol (PEG), and drug for assessing the application of chitosan-PEG nanocomposites in drug delivery and also to assess the effect of different molecular weights of PEG on nanocomposite characteristics. The casting/solvent evaporation method was used to prepare chitosan-PEG nanocomposite films incorporating piroxicam-beta-cyclodextrin. In order to characterize the morphology and structure of nanocomposites, X-ray diffraction technique, scanning electron microscopy, thermogravimetric analysis, and Fourier transmission infrared spectroscopy were used. Drug content uniformity test, swelling studies, water content, erosion studies, dissolution studies, and anti-inflammatory activity were also performed. The permeation studies across rat skin were also performed on nanocomposite films using Franz diffusion cell. The release behavior of films was found to be sensitive to pH and ionic strength of release medium. The maximum swelling ratio and water content was found in HCl buffer pH 1.2 as compared to acetate buffer of pH 4.5 and phosphate buffer pH 7.4. The release rate constants obtained from kinetic modeling and flux values of ex vivo permeation studies showed that release of piroxicam-beta-cyclodextrin increased with an increase in concentration of PEG. The formulation F10 containing 75% concentration of PEG showed the highest swelling ratio (3.42+/ 0.02) in HCl buffer pH 1.2, water content (47.89+/-1.53%) in HCl buffer pH 1.2, maximum cumulative drug permeation through rat skin (2405.15+/-10.97 MUg/cm2) in phosphate buffer pH 7.4, and in vitro drug release (35.51+/-0.26%) in sequential pH change mediums, and showed a significantly (p<0.0001) higher anti-inflammatory effect (0.4 cm). It can be concluded from the results that film composition had a particular impact on drug release properties. The different molecular weights of PEG have a strong influence on swelling, drug release, and permeation rate. The developed films can act as successful drug delivery approach for localized drug delivery through the skin. PMID- 29567262 TI - Oxidative stress evoked damages leading to attenuated memory and inhibition of NMDAR-CaMKII-ERK/CREB signalling on consumption of aspartame in rat model. AB - Many controversial reports are available on the use of aspartame as it releases methanol as one of its metabolite during metabolism. The present study proposes to investigate whether long term (90 days) aspartame (40 mg/kg b.wt) administration could induce oxidative stress and alter the memory in Wistar strain male albino rats. To mimic the human methanol metabolism, methotrexate (MTX)-treated rats were included as a model to study the effects of aspartame. Wistar strain albino rats were administered with aspartame (40 mg/kg b.wt) orally and studied along with controls and MTX-treated controls. Aspartame interfered in the body weight and corticosterone levels in the rats. A marked increase in the mRNA and protein expression of neuronal nitric oxide synthase (nNOS) and induced nitric oxide synthase (iNOS) which resulted in the increased nitric oxide radical's level indicating that aspartame is a stressor. These reactive nitrogen species could be responsible for the altered cell membrane integrity and even cause death of neurons by necrosis or apoptosis. The animals showed a marked decrease in learning, spatial working and spatial recognition memory deficit in the Morris water maze and Y-maze performance task which could have resulted due to reduced hippocampal acetylcholine esterase (AChE) activity. The animal brain homogenate also revealed the decrease in the phosphorylation of NMDAR1-CaMKII ERK/CREB signalling pathway, which well documents the inhibition of phosphorylation leads to the excitotoxicity of the neurons and memory decline. This effect may be due to methanol which may also activate the NOS levels, microglia and astrocytes, inducing neurodegeneration in brain. Neuronal shrinkage of hippocampal layer due to degeneration of pyramidal cells revealed the abnormal neuronal morphology of pyramidal cell layers in the aspartame treated animals. These findings demonstrate that aspartame metabolites could be a contributing factor for the development of oxidative stress in the brain.

AB - Green synthetic route of silver nanoparticles (AgNPs) has already been proved to be an advantageous over other physico-chemical approaches due to its simplicity, cost effectiveness, ecofriendly and nontoxicity. In this finding, aqueous Wedelia chinensis leaf extract (WLE) mediated synthesis of AgNPs was approached. Surface plasmon resonance (SPR) band at 408 nm preliminary indicated the formation of AgNPs, while TEM and XRD characterization confirmed the formation of spherically shaped and crystalline AgNPs with an average size of 31.68 nm, respectively. The plausible biomolecules in the aqueous leaf extract responsible for the reduction and stabilization of AgNPs were identified by FTIR analysis and found to be polyphenolic groups in flavonoid. Further, synthesized AgNPs was explored for different biological applications. Biosynthesized AgNPs showed significant free radical scavenging activity as compared to Wedelia leaf extract and antibacterial activity against clinically isolated test pathogens where Gram-negative bacteria were found more susceptible to AgNPs than Gram-positive one. In addition, in vitro cytotoxic response was also evaluated on hepatocellular carcinoma Hep G2 cell lines and showed a dose-dependent cytotoxic response with an IC50 value of 25 MUg/mL.

AB - Severe food restriction (FR), as observed in disorders like anorexia nervosa, has been associated to the reduction of estrogen levels, which in turn could lead to anxiety development. Estrogen receptors, mainly ERbeta type, are commonly found in the dorsal raphe nucleus (DRN) neurons, an important nucleus related to anxiety modulation and the primary source of serotonin (5-HT) in the brain. Taking together, these findings suggest an involvement of estrogen in anxiety modulation during food restriction, possibly mediated by ERbeta activation in serotonergic DRN neurons. Thus, the present study investigated the relationship between food restriction and anxiety-like behavior, and the involvement of DRN and ERbeta on the modulation of anxiety-like behaviors in animals subjected to FR. For that, female Fischer rats were grouped in control group, with free access to food, or a FR group, which received 40% of control intake during 14 days. Animals were randomly treated with 17beta-estradiol (E2), DPN (ERbeta selective agonist), or their respective vehicles, PBS and DMSO. Behavioral tests were performed on Elevated T-Maze (ETM) and Open Field (OF). Our results suggest that FR probably reduced the estrogen levels, since the remained in the non-ovulatory cycle phases, and their uterine weight was lower when compared to control group. The FR rats showed increased inhibitory avoidance latency in theETM indicating that FR is associated with the development of an anxiety-like state. The injections of both E2 and DPN into DRN of FR animals had an anxiolytic effect. Those data suggest thatanxiety-like behavior induced by FR could be mediated by a reduction of ERbeta activation in the DRN neurons, probably due to decreased estrogen levels. PMID- 29567266 TI - Early risk factors for mortality in children with seizure and/or impaired consciousness accompanied by fever without known etiology. AB - BACKGROUND: Children who present with seizure and/or impaired consciousness accompanied by fever without known etiology (SICF) may be diagnosed with either acute encephalopathy (AE) or febrile seizure (FS). Although approximately 5% of AE cases are fatal, it is difficult to identify fatal cases among children with SICF, which are often critical by the time of diagnosis. Thus, early prediction of outcomes for children with SICF, prior to diagnosis, may help to reduce mortality associated with AE. The aim of the present study was to identify clinical and laboratory risk factors for mortality acquired within 6 h of onset among children with SICF. METHODS: We retrospectively reviewed the medical records of children who had been admitted to Kobe Children's Hospital (Kobe, Japan) with SICF between October 2002 and September 2015. We compared clinical and laboratory characteristics acquired within 6 h of onset and outcomes between survivors and non-survivors using univariate and multivariate analyses. RESULTS: The survivor and non-survivor groups included 659 and nine patients, respectively. All patients in the non-survivor group received a final diagnosis of AE. Univariate analysis revealed significant differences between the groups with regard to seizure duration and the following laboratory parameters: aspartate transaminase (AST), alanine aminotransferase, lactate dehydrogenase, sodium, and lactate. The multivariate analysis identified AST as a significant independent factor associated with mortality. CONCLUSIONS: Elevation of AST within 6 h of onset is independently correlated with mortality in children with SICF. Our result may elucidate earlier intervention for patients with high risk of mortality. PMID- 29567267 TI - Determination of as-discarded methane potential in residential and commercial municipal solid waste. AB - Methane generation potential, L0, is a primary parameter of the first-order decay (FOD) model used for prediction and regulation of landfill gas (LFG) generation in municipal solid waste (MSW) landfills. The current US EPA AP-42 default value for L0, which has been in place for almost 20 years, is 100 m3 CH4/Mg MSW as discarded. Recent research suggests the yield of landfilled waste could be less than 60 m3 CH4/Mg MSW. This study aimed to measure the L0 of present-day residential and commercial as-discarded MSW. In doing so, 39 waste collection vehicles were sorted for composition before samples of each biodegradable fraction were analyzed for methane generation potential. Methane yields were determined for over 450 samples of 14 different biodegradable MSW fractions, later to be combined with moisture content and volatile solids data to calculate L0 values for each waste load. An average value of 80 m3 CH4/Mg MSW was determined for all samples with 95% of values in the interval 74-86 m3 CH4/Mg MSW as-discarded. While no statistically significant difference was observed, commercial MSW yields (mean 85, median 88 m3 CH4/Mg MSW) showed a higher average L0 than residential MSW (mean 75, median 71 m3 CH4/Mg MSW). Many methane potential values for individual fractions described in previous work were found within the range of values determined by BMP in this study. PMID- 29567268 TI - Altered hair endocannabinoid levels in mothers with childhood maltreatment and their newborns. AB - The endocannabinoid (EC) system possesses anti-inflammatory properties and seems to be altered in trauma-exposed individuals. In an intergenerational approach, this study investigated the link between childhood maltreatment (CM) experiences and alterations in the EC system. Hair samples of N = 142 mothers and N = 91 newborns were analyzed, retrospectively assessing EC regulation during the last trimester of pregnancy with four ECs: 1-arachidonoylglycerol (1-AG), N oleoylethanolamide (OEA), N-stearoylethanolamide (SEA), and N palmitoylethanolamide (PEA). Compared to mothers without CM, hair of mothers with CM showed significantly higher levels of 1-AG and lower levels of SEA. Newborns of mothers with CM exhibited higher levels of 1-AG and OEA. Furthermore, the higher the severity of maternal CM, the lower were maternal SEA levels and the higher neonatal OEA levels. Findings indicate altered EC levels during the last trimester of pregnancy in mothers with CM and their developing fetus, highlighting potential intergenerational effects from one generation to the other. PMID- 29567269 TI - Quality assurance in CT: implementation of the updated national diagnostic reference levels using an automated CT dose monitoring system. AB - AIM: To evaluate the implementation of the updated computed tomography (CT) diagnostic reference levels (DRLs) from the German Federal Office for Radiation Protection into clinical routine using an automatic CT dose monitoring system. METHODS AND MATERIALS: CT radiation exposure was analysed before and after implementing the updated national DRLs into routine clinical work in 2016. After the implementation process, institutional CT protocols were mapped to the anatomical regions for which DRLs were provided. Systematically, protocols that exceeded the thresholds were optimised and analysed in detail. The CT radiation output parameters analysed were volumetric CT dose index (CTDIvol) and dose length product (DLP). Three radiologists evaluated subjective image quality using a three-point Likert scale. RESULTS: The study included 94,258 CT series (from 27,103 CT examinations) in adult patients performed in 2016. When averaged over all body regions with available DRL, institutional CTDIvol/DLP values were always below the DRLs (65.2+/-32.9%/67.3+/-41.5% initially; 59.4+/-32%/60.5+/-39.9% after optimisation). Values exceeding the national DRLs were found for pelvis (n=268; CTDIvol 107.7+/-65.7%/DLP 106.3+/-79.3%), lumbar spine (n=91; 160.8+/ 74.7%/175.2+/-104.1%), and facial bones (n=527; 108+/-39%/152.7+/-75.7%). After optimisation, CTDIvol and DLP were 87.9+/-73%/87.8+/-80.8% for the pelvis, 67.8+/ 33.2%/74.5+/-50.6% for the lumbar spine and 95.1+/-45.8%/133.3+/-74.6% for the viscerocranium. CONCLUSION: An automatic CT dose monitoring system enabled not only comprehensive monitoring of a DRL implementation process but can also help to optimise radiation exposure. PMID- 29567270 TI - Pretreatment MRI features associated with diagnostic accuracy of post-treatment MRI after neoadjuvant chemotherapy. AB - AIM: To investigate whether pretreatment magnetic resonance imaging (MRI) features are associated with diagnostic accuracy of post-treatment MRI for predicting pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) in patients with breast cancer. MATERIALS AND METHODS: From January 2005 and December 2016, 221 consecutive patients (mean age, 50 years; range, 20-81 years) who had undergone NAC, breast MRI before and after NAC, and surgery for invasive breast cancer were enrolled. Pretreatment and post-treatment MRI images were reviewed. Radiological complete response (rCR) was defined as the absence of both early and late enhancement on MRI after NAC. The association of pretreatment MRI features and post-treatment MRI diagnostic accuracy was assessed by using logistic regression analysis. RESULTS: Among 221 patients, 60 (27.1%) underwent pCR after NAC. The diagnostic accuracy of post-treatment MRI was 84.2% (186/221). False-positive diagnosis occurred in 21 cases and false-negative diagnosis occurred in 14 cases. Of pretreatment features, the presence of peritumoural oedema (odds ratio, 3; 95% confidence interval [CI]: 1.1, 8.0; p=0.03) and HER2 (human epidermal growth factor receptor 2)-positive status (odds ratio, 3.4; 95% CI: 1.2, 9.9; p=0.02) were significantly associated with false-positive MRI results. Dense fibroglandular tissue (odds ratio, 10.8; 95% CI: 1.1, 105.2; p=0.04), presence of rim enhancement (odds ratio, 7.5; 95% CI: 1.2, 38.3; p=0.02) and oestrogen receptor (ER)-positive status (odds ratio, 6.3; 95% CI: 1.2, 32.5; p=0.03) were significantly associated with false-negative MRI results. CONCLUSION: Pretreatment MRI features and cancer subtypes may be associated with diagnostic accuracy of post-treatment MRI after NAC in patients with breast cancer.

PMID- 29567272 TI - The BET inhibitor INCB054329 reduces homologous recombination efficiency and augments PARP inhibitor activity in ovarian cancer. AB - OBJECTIVE: Homologous recombination (HR)-proficient ovarian tumors have poorer clinical outcomes and show resistance to poly ADP ribose polymerase inhibitors (PARPi). A subset of HR-proficient ovarian tumors show amplification in bromodomain and extra-terminal (BET) genes such as BRD4. We aimed to test the hypothesis that BRD4 inhibition sensitizes ovarian cancer cells to PARPi by reducing HR efficiency and increasing DNA damage. METHODS: HR-proficient ovarian cancer cell lines (OVCAR-3, OVCAR-4, SKOV-3, UWB1.289+BRCA1) were treated with BRD4-targeting siRNA, novel (INB054329, INCB057643) and established (JQ1) BET inhibitors (BETi) and PARPi (olaparib, rucaparib). Cell growth and viability were assessed by sulforhodamine B assays in vitro, and in SKOV-3 and ovarian cancer patient-derived xenografts in vivo. DNA damage and repair (pH2AX, RAD51 and BRCA1 foci formation, and DRGFP HR reporter activity), apoptosis markers (cleaved PARP, cleaved caspase-3, Bax) and proliferation markers (PCNA, Ki67) were assessed by immunofluorescence and western blot. RESULTS: In cultured cells, inhibition of BRD4 by siRNA or INCB054329 reduced expression and function of BRCA1 and RAD51, reduced HR reporter activity, and sensitized the cells to olaparib-induced growth inhibition, DNA damage induction and apoptosis. Synergy was observed between all BETi tested and PARPi. INCB054329 and olaparib also co-operatively inhibited xenograft tumor growth, accompanied by reduced BRCA1 expression and proliferation, and increased apoptosis and DNA damage. CONCLUSIONS: These results provide strong rationale for using BETi to extend therapeutic efficacy of PARPi to HR-proficient ovarian tumors and could benefit a substantial number of women diagnosed with this devastating disease. PMID- 29567276 TI - Calycophyllum spruceanum BENTH ameliorates acute inflammation in mice. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Calycophyllum spruceanum (Benth.) Hook. F. ex K. Schum. is widely distributed in the Amazonian region of Brazil, where it is popularly known as "mulateiro", "pau-mulato", "pau-mulato-de-varzea", "escorrega macaco" or "pau-marfim". Preparations of C. spruceanum barks are used in the form of tea, poultice or skin patches to treat stomach diseases, skin inflammation and uterus tumors. PURPOSE OF THE STUDY: To investigate in vivo the antinociceptive and anti-inflammatory activities of the hydroalcoholic extract of Calycophyllum spruceanum barks (HECSb) in order to validate its popular usage in inflammatory conditions. MATERIALS AND METHODS: Chemical analysis of HECSb was performed using the UHPLC-MS system. Mice were treated per oral with HECSb (5-5000 mg/kg) and evaluated for acute toxicity (during 15 days); motor activity (Rota rod test); body weight (up to 72 h); antinociceptive activity: writhes induced by 0.8% acetic acid; paw licking induced by 2.5% formalin; paw withdrawal (von Frey test) induced by carrageenan (300 MUg) or PGE2 (100 ng); anti-inflammatory (paw edema model). For histopathological analysis subplantar tissue fragments were collected 1 h after paw edema induction. RESULTS: HECSb chemical analysis revealed the presence of caffeoylquinic derivatives, small organic acids, and phenolic compounds. HECSb showed antinociceptive effect, reducing the number of acetic acid-induced writhes by 72% at 120 mg/kg, paw licking (phase 2- Formalin test) by 33% at 60 mg/kg and 49% at 120 mg/kg; and paw withdrawal elicited by carrageenan (53% at 120 mg/kg) and PGE2 (120 mg/kg) at 0.5 h (48%) and 1 h (45%). HECSb (120 mg/kg) also inhibited the paw edema elicited both by carrageenan (48%) and PGE2 (92%). Histopathological analysis (leukocyte infiltration, edema, focal areas of hemorrhage, vascular congestion) of HECSb treatment at 120 mg/kg demonstrated normal morphology [median 0 (0,1)] compared to PGE2, showing severe alterations [median 3 (2,3); p = 0,0035]. HECSb did not induce acute toxicity nor altered body mass or motor coordination. CONCLUSIONS: HECSb shows antinociceptive and anti-inflammatory effect in mice without inducing apparent acute toxicity. PMID- 29567277 TI - Castanea mollissima shell prevents an over expression of inflammatory response and accelerates the dermal wound healing. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Castanea mollissima shell (CMS) has been used for wound healing in China as traditional medicine. The shell is directly applied on the wounded skin as fine powder or as water maceration. AIM OF THE STUDY: To investigate the wound healing activity of CMS and the potential mechanism of anti inflammatory activity. MATERIALS AND METHODS: The effects of ethanol extract of CMS (ECMS) on nitricoxide (NO), tumor necrosis factor (TNF)-alpha and interleukin (IL)- 6 productions in lipopolysaccharide (LPS)-treated RAW 264.7 cells were explored by enzyme linked immunosorbent assay (ELISA) in vitro. To study wound healing properties of ECMS in vivo, excision and incision wound models were performed on rats. Inflammatory cytokines from wound biopsies such as NO, TNF alpha and IL-6 production were tested by ELISA. mRNA levels of iNOS, cyclooxygenase (COX) -2 and TNF-alpha were detected by real-time Polymerase Chain Reaction (PCR), and protein levels of IL-1beta and Heme Oxygenase (HO) -1 were analyzed by Western blotting. RESULTS: ECMS potently inhibited LPS-induced production of IL-6, NO and TNF-alpha in RAW 264.7 cells. The presence of quercetin, kaempferol, ursolic acid and gallic acid in ECMS might be responsible for its anti-inflammatory activity. 3% and 5% w/w ECMS significantly accelerated the wound healing process in both wound models, evidenced by the faster rate of wound contraction, epithelialization, increased hydroxyproline content, high tensile strength, decreased level of inflammatory markers compared to the control group. Histopathological studies also revealed the amelioration of wound healing by re-epithelialization, collagenation and vascularization of wounded skin sample in ECMS treated groups. CONCLUSION: The experimental data revealed that CMS had ability to prevent exaggerated inflammation and accelerates wound epithelialization and might be beneficial for healing dermal wounds. PMID- 29567278 TI - Antinociceptive activity of Inula britannica L. and patuletin: In vivo and possible mechanisms studies. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Inula britannica L. is a predominant medicinal plant traditionally utilized in the treatments of arthritis and back pain in Iranian folk medicine. AIM OF THE STUDY: The purpose of this research was to evaluate the antinociceptive effects of Inula britannica L. flower essential oil (IBLEO) and one of its major constituents, Patuletin (Pn), in male mice. MATERIALS AND METHODS: In this study, we used pain assessment tests including acetic acid-induced writhing, tail-flick (TF), formalin induced paw licking (FIPL) model, and glutamate-induced paw licking (GPL). For understanding the supposed antinociceptive mechanisms of IBLEO, opioid and L-arginine/NO/cGMP/ KATP pathways were examined. RESULTS: In the TF, writhing, GPL, and FIPL tests, a dosage of 100 mg/kg of IBLEO showed noteworthy antinociceptive effects in comparison with control (p < 0.05). In writhing test, administration of selective opioid antagonists (naltrindole, nor-binaltorphimine, and naloxonazine) attenuated the antinociceptive effect of IBLEO in comparison with control (p < 0.001). Both methylene blue and glibenclamide blocked the antinociceptive effect of IBLEO (p < 0.05), but the administration of L-arginine or sodium nitroprusside fundamentally potentiated the antinociception induced by IBLEO in phase II of the FIPL (p < 0.05). Additionally, patuletin showed significant antinociceptive effects in writhing, FIPL, and GPL tests (p < 0.01). CONCLUSION: The results of this examination showed that IBLEO and Pn have antinociceptive effects. The modulation of glutamatergic systems by opioid receptors could be involved, at least in part, in these effects. Our data also suggest the activation of the L arginine/NO/cGMP/KATP pathway in IBLEO antinociceptive effects. PMID- 29567279 TI - [Neuroendocrine tumors of the breast: Myth or reality? A systematic review]. AB - Primary neuroendocrine breast carcinomas are rare and little-known tumors. Only a limited number of studies on neuroendocrine breast carcinomas have been reported in the literature, and the vast majority of them are small retrospective series or case reports. According to the World Health Organization (WHO), they account for only 2 % to 5 % of breast cancers. Their diagnosis relies on the presence of a neuroendocrine architecture and the expression of neuroendocrine markers (chromogranin A and/or synaptophysin). The revised 2012 WHO classification subdivides them into three categories: (i) well-differentiated neuroendocrine carcinomas, (ii) poorly differentiated neuroendocrine carcinomas or small-cell carcinomas, and (iii) invasive breast carcinomas with neuroendocrine differentiation. Their clinical features and radiological characteristics are not different from those of other types of breast cancer. Because of discordant results, their clinical outcome is still poorly defined. So far, no standard treatment has been established, and most clinicians draw on their experience of invasive ductal cancer. The role of specific treatments like platinum-based chemotherapy, somatostatin analogues, peptide receptor radionucleide therapy or temozolomide remains unclear. A better knowledge of the molecular pathways involved in their carcinogenesis could help to identify new potential therapeutic targets. The efficacy of targeted therapies has to be studied. PMID- 29567280 TI - [Hepatocellular carcinoma: Increase in incidence or future plague?] AB - Hepatocellular carcinoma is the third most frequent cause of cancer death worldwide, particularly in Asia and Africa. Most cases complicate an underlying liver cirrhosis due to hepatitis B or C chronic virus infection or alcoholic abuse. But, following the current epidemics of obesity and type 2 diabetes, it appears that these diseases, associated in metabolic syndrome, are responsible for non alcoholic fatty liver disease at risk of HCC frequently before the stage of cirrhosis. Recent hypotheses consider that in the near future, cancer deaths due to HCC will overpass in USA those due to breast or colorectal cancers. Governments should develop policies to prevent obesity, type 2 diabetes and the metabolic syndrome as well as fight against alcoholism and hepatitis B and C virus infections. PMID- 29567281 TI - [Multidisciplinary oncopalliative meeting: Aims and pratical recommendations]. AB - Progress leads to increase life duration at the metastatic stage but metastatic disease is most often lethal. Decision-making is necessary for an increasing period of care, beyond evidence-based medicine, dealing with complexity and uncertain benefit/risk ratio. This requires to inform the patient realistically, to discuss prognostication, to develop anticipated written preferences. These changes mean to pass from a medicine based on informed consent to medicine based on respect of the patient wishes even if it can be complex to determine. A new multidisciplinarity is needed, centered on the meaning of the care, the proportionality of the care, the anticipated patient trajectory. The ASCO has published recommendations on early palliative care. The timing and the quality of the discussion between palliative care specialists and oncologists is crucial. We propose 10 steps to organize a multidisciplinary onco-palliative meeting, as it appears the key for the organization of care in non-curable disease.

AB - PURPOSE: Bowel dysfunction is a common, persistent long-term effect of treatment for rectal cancer survivors. Survivors often use dietary modifications to maintain bowel control. There are few evidence-based interventions to guide survivors on appropriate diet modifications for bowel symptom management. The purpose of this paper is to describe the development and design of the Altering Intake, Managing Symptoms (AIMS) intervention to support bowel dysfunction management in rectal cancer survivors. METHODS: The AIMS intervention is a ten session, telephone-based diet behavior change intervention delivered by trained health coaches. It uses dietary recall, participant-completed food and symptom diaries, and health coaching guided by motivational interviewing to promote bowel symptom management and improved diet quality. Based on the Chronic Care Self Management Model (CCM), the AIMS Intervention is designed to improve self efficacy and self-management of bowel symptoms by coaching survivors to appropriately modify their diets through goal setting, self-monitoring, and problem-solving. The intervention targets survivors with stage I-III rectosigmoid colon/rectum cancer who are 6 months post-treatment, 21 years and older, and English-speaking. CONCLUSIONS: The design and development process described in this paper provides an overview and underscores the potential of the AIMS intervention to positively impact the quality of long-term survivorship for rectal cancer survivors. An ongoing pilot study will inform the design and development of future multi-site Phase II and III randomized trials.

PMID- 29567287 TI - Surgical Management of Supratentorial Intracerebral Hemorrhages: Endoscopic Versus Open Surgery. AB - OBJECTIVE: Intracerebral hemorrhage continues to be a major global problem. No standard treatment or surgical procedure has been identified for intracerebral hemorrhages. High morbidity and mortality rates caused by conventional approaches and the disease itself have necessitated more-invasive treatment methods. The endoscopic approach is a more minimally invasive method than craniotomy, which is another alternative surgical treatment. METHODS: We compared intracerebral hematoma drainage in 2 groups of 17 patients each, treated with minimally invasive endoscopic method versus craniotomy. All the patients were treated for supratentorial spontaneous hemorrhage between December 2013 and February 2017 at the Neurosurgery Clinic of Ankara University Faculty of Medicine. RESULTS: We retrospectively evaluated 34 patients surgically treated between December 2013 and February 2017. All patients underwent surgery within the first 24 hours. Patients in the early surgery group had better surgical outcomes. In the neuroendoscopic group, Glasgow Coma Scale increased from 6 to 11 at 1 week postoperatively compared with 5 to 9 in the craniotomy group. CONCLUSIONS: Minimally invasive endoscopic hematoma evacuation may be a good alternative surgical method for treating supratentorial spontaneous cerebral hematomas.

METHODS: This is a methodologic study conducted in the children's neurosurgery outpatient clinic of a university hospital. The content validity index with a concordance of >=0.78 was used for validation. Content was validated with the participation of 5 nurses and 3 neurosurgeons, and appearance was validated with the participation of 9 informal caregivers of children with hydrocephalus. RESULTS: A 21-page journal was created to address hydrocephalus and its treatment. The content and semantics of this material were validated with a universal content validity index of 0.90 and 0.98, respectively. CONCLUSIONS: Content and appearance of the educational material for informal caregivers of children with hydrocephalus were successfully validated and considered suitable and user-friendly for health education. PMID- 29567290 TI - Effects of Curcumin on Bone Loss and Biochemical Markers of Bone Turnover in Patients with Spinal Cord Injury. AB - BACKGROUND: Osteoporosis is one of the most common problems of patients with spinal cord injuries (SCIs). The current study aimed to evaluate the antiosteoporotic effects of curcumin on densitometry parameters and biomarkers of bone turnovers among patients with SCI. MATERIALS AND METHODS: The current controlled clinical trial was conducted among 100 patients with SCI referred to an outpatient clinic of rehabilitation in Ilam City, Iran, in 2013-2015. The intervention group received 110/mg/kg/day curcumin for 6 months and the control group received placebo. Bone mineral density (BMD) was measured in all patients. The level of procollagen type I N-terminal propeptide, serum carboxy-terminal telopeptide of type I collagen, osteocalcin, and bone-specific alkaline phosphates were compared before and after study. RESULTS: BMD indicators of lumbar, femoral neck, and total hip in the control group significantly decreased compared with the beginning of study. However, in the curcumin group, a significant increase was observed in BMD indicators of lumbar, femoral neck, and hip at the end of study compared with the beginning. There was also a significant difference between interventional and control groups for the mean BMD of femoral neck and hip at the end of study (0.718 +/- 0.002 g/cm2 vs. 0.712 +/- 0.003 g/cm2 and 0.742 +/- 0.031 g/cm2 vs. 0.692 +/- 0.016 g/cm2, respectively). CONCLUSIONS: Curcumin, via modulation of densitometry indices and bone resorption markers, showed inhibitory effects on the process of osteoporosis. Treatment with curcumin was significantly associated with a decrease in the osteoporosis progression and bone turnover markers of patients with SCI after 6 months. PMID- 29567292 TI - N-terminome and proteogenomic analysis of the Methylobacterium extorquens DM4 reference strain for dichloromethane utilization. AB - : Methylobacterium strains can use one-carbon compounds, such as methanol, for methylotrophic growth. In addition to methanol, a few strains also utilize dichloromethane, a major industrial chlorinated solvent pollutant. With a fully assembled and annotated genome, M. extorquens DM4 is the reference bacterium for aerobic dichloromethane degradation. The doublet N-terminal oriented proteomics (dN-TOP) strategy was applied to further improve its genome annotation and a differential proteomics approach was performed to compare M. extorquens DM4 grown either with methanol or dichloromethane as the sole source of carbon and energy. These approaches led to experimental confirmation of 259 hypothetical proteins, correction of 78 erroneous predicted start codons, discovery of 39 new proteins and annotation of 66 signal peptides, including essential enzymes involved in methylotrophic growth. SIGNIFICANCE: Dichloromethane (methylene chloride, CH2Cl2, DCM) is one of the most widely used industrial halogenated solvents and a potential carcinogen. Microbial rehabilitation of worldwide-contaminated sites involves DCM breakdown by bacteria that are able to grow using this pollutant as their sole carbon and energy source. The most-studied methylotrophic DCM degrader is Methylobacterium extorquens strain DM4. Proteomic studies of the Methylobacterium genus have been performed previously, but genome-wide investigation of N-termini of expressed proteins has not yet been performed. Differential quantitative proteomic analysis also opens new research perspectives to better monitor and understand bacterial growth with DCM. PMID- 29567291 TI - Computed Tomography Angiography Evaluation of Risk Factors for Unstable Intracranial Aneurysms. AB - OBJECTIVE: To evaluate risk factors for instability in intracranial aneurysms (IAs) using computed tomography angiography (CTA). METHODS: A total of 614 consecutive patients diagnosed with 661 IAs between August 2011 and February 2016 were reviewed. Patients and IAs were divided into stable and unstable groups. Along with clinical characteristics, IA characteristics were evaluated by CTA. Multiple logistic regression analysis was used to identify the independent risk factors associated with unstable IAs. Receiver operating characteristic (ROC) curve analysis was performed on the final model, and optimal thresholds were obtained. RESULTS: Patient age (odds ratio [OR], 0.946), cerebral atherosclerosis (CA; OR, 0.525), and IAs located at the middle cerebral artery (OR, 0.473) or internal carotid artery (OR, 0.512) were negatively correlated with instability, whereas IAs with irregular shape (OR, 2.157), deep depth (OR, 1.557), or large flow angle (FA; OR, 1.015) were more likely to be unstable. ROC analysis revealed threshold values of age, depth, and FA of 59.5 years, 4.25 mm, and 87.8 degrees , respectively. CONCLUSIONS: The stability of IAs is significantly affected by several factors, including patient age and the presence of CA. IA shape and location also have an impact on the stability of IAs. Growth into an irregular shape, with a deep depth, and a large FA are risk factors for a change in IAs from stable to unstable.

AB - : Arachidonic acid (ARA) is a valuable polyunsaturated fatty acid produced by Mortierella alpina. Although some strategies such as nitrogen supplementation have shown the potential to affect the aging of M. alpina in ways which enable it to produce more ARA, the underlying mechanism remains elusive. Herein, we conducted a systematical analysis of the lipid droplet proteome, as well as the whole-cell proteome and metabolome, in order to elucidate how and why two different nitrogen sources (KNO3 and urea) affect the aging of M. alpina and the corresponding ARA concentration. We found that KNO3 promoted the ARA concentration, while urea accelerated lipid consumption and stimulated the decomposition of mycelia. Although both KNO3 and urea activated carbohydrate metabolic pathways, KNO3 exerted a stronger promoting effect on the pentose phosphate pathway and induced the lipid droplets to participate in the citrate pyruvate cycle. The activities of malic enzyme and isocitrate dehydrogenase were also promoted more by KNO3. These pathways provided additional substrates and reducing power for ARA synthesis and ROS elimination. Accordingly, since urea showed a weaker promotion of the related pathways, it caused a depression of the antioxidant system and a consequent increase of ROS. These findings facilitate the design of nitrogen supplementation strategies to achieve higher ARA concentrations, and provide guidance for deciphering the mechanisms of similar aging phenomena in other oleaginous microorganisms. SIGNIFICANCE: Polyunsaturated fatty acids such as arachidonic acid (ARA) are valuable nutrients, which play important roles in preventing numerous diseases and facilitating development. Although it has been found for years that ARA production will be increased in the aging process of Mortierella alpina (M. alpina) and nitrogen sources are involved in this process, the underlying mechanism for this phenomenon remains unknown. In this work, we used the subcellular proteomics, whole-cell proteomics and metabolomics methods to explore the mechanisms by which two different nitrogen (KNO3 and urea) affected the aging process of M. alpina. Finally, we gave some new insights for the mechanisms mentioned above. This finding will fuel the technology developments for the ARA production using microbes.

AB - BACKGROUND: International travel facilitates global spread of sexually transmitted infections (STI). Travellers could contribute to onward transmission of pathogens rarely encountered at home and export new strains to the destination. The aim was to systematically examine evidence regarding determinants of travel-related sexual risk-taking and identify knowledge gaps and areas for targeted interventions. METHOD: Articles published in peer-reviewed journals from 2000 to 2017 were screened in 6 databases and assessed for relevance against criteria. Data was extracted for factors associated with travel related STI or proxies. Meta-analyses estimated pooled prevalence of casual sex and non-condom use. Adjusted odds ratios of predictors were pooled to generate a combined estimate. RESULT: Forty-nine articles qualified for inclusion. A heterogeneity test indicated variation across studies. The pooled prevalence of casual travel sex was 35% and prevalence of non-condom use 17%. Expectations of casual sex strongly predicted sex with a new partner when travelling abroad. Planning to have sex indicated condom use. CONCLUSION: The studies largely represented sub-groups of risk-taking populations from a European context, indicating substantial knowledge gaps. Studies investigating migrants travelling to visit friends and relatives, older travellers, and female travelers are needed. Post-travel harm reduction activities may serve as a focus for future interventions.

AB - A series of 3-substituted pyrazolopyrimidine derivatives as BTK inhibitors were designed by structure-based drug design and they were synthesized, evaluated by enzyme-based assay and anti-proliferation against Ramos and Raji cells. Most of them displayed good inhibitory activities against both BTK and B-cell lymphoblastic leukemia lines in vitro. Among them, compound 8a exhibited excellent potency (IC50 = 7.95 nM against BTK enzyme, 8.91 MUM against Ramos cells and 1.80 MUM against Raji cells), with a better hydrophilicity (ClogP = 3.33). These explorations provided new clues to discover 3-substituted pyrazolopyrimidine derivatives as novel anti-tumor agents. PMID- 29567296 TI - Discovery of a novel allosteric inhibitor scaffold for polyadenosine-diphosphate ribose polymerase 14 (PARP14) macrodomain 2. AB - The polyadenosine-diphosphate-ribose polymerase 14 (PARP14) has been implicated in DNA damage response pathways for homologous recombination. PARP14 contains three (ADP ribose binding) macrodomains (MD) whose exact contribution to overall PARP14 function in pathology remains unclear. A medium throughput screen led to the identification of N-(2(-9H-carbazol-1-yl)phenyl)acetamide (GeA-69, 1) as a novel allosteric PARP14 MD2 (second MD of PARP14) inhibitor. We herein report medicinal chemistry around this novel chemotype to afford a sub-micromolar PARP14 MD2 inhibitor. This chemical series provides a novel starting point for further development of PARP14 chemical probes. PMID- 29567297 TI - Fine-tuning the physicochemical properties of peptide-based blood-brain barrier shuttles. AB - N-methylation is a powerful method to modify the physicochemical properties of peptides. We previously found that a fully N-methylated tetrapeptide, Ac-(N MePhe)4-CONH2, was more lipophilic than its non-methylated analog Ac-(Phe)4 CONH2. In addition, the former crossed artificial and cell membranes while the latter did not. Here we sought to optimize the physicochemical properties of peptides and address how the number and position of N-methylated amino acids affect these properties. To this end, 15 analogs of Ac-(Phe)4-CONH2 were designed and synthesized in solid-phase. The solubility of the peptides in water and their lipophilicity, as measured by ultra performance liquid chromatography (UPLC) retention times, were determined. To study the permeability of the peptides, the Parallel Artificial Membrane Permeability Assay (PAMPA) was used as an in vitro model of the blood-brain barrier (BBB). Contrary to the parent peptide, the 15 analogs crossed the artificial membrane, thereby showing that N-methylation improved permeability. We also found that N-methylation enhanced lipophilicity but decreased the water solubility of peptides. Our results showed that both the number and position of N-methylated residues are important factors governing the physicochemical properties of peptides. There was no correlation between the number of N-methylated amide bonds and any of the properties measured. However, for the peptides consecutively N-methylated from the N-terminus to the C-terminus (p1, p5, p11, p12 and p16), lipophilicity correlated well with the number of N methylated amide bonds and the permeability of the peptides. Moreover, the peptides were non-toxic to HEK293T cells, as determined by the 3-(4,5 dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay. PMID- 29567298 TI - Associations between Gut Microbiota and Common Luminal Intestinal Parasites. AB - The development and integration of DNA-based methods in research and clinical microbiology laboratories have enabled standardised and comprehensive detection and differentiation of the microbes colonising our guts. For instance, the single celled parasites Blastocystis and Dientamoeba appear to be much more common than previously thought, especially so in healthy individuals. While increasing evidence appears to suggest limited pathogenicity of these parasites, next generation-sequencing-based studies have helped us to appreciate links between parasite colonisation and certain host phenotypical characteristics and gut microbial profiles. The fundamental question remains as to whether such parasites are merely indicators or active manipulators of gut microbiota structure and function. In this article, we collate existing evidence that these parasites are, at minimum, indicators of intestinal microbiota structure. PMID- 29567299 TI - Association Between Self-reported Physical Activity and Skin Autofluorescence, a Marker of Tissue Accumulation of Advanced Glycation End Products in Adults With Type 1 Diabetes: A Cross-sectional Study. AB - PURPOSE: The accumulation of advanced glycation end products (AGEs) in local tissue is an important cause of low-grade inflammation and oxidative stress and is linked to late diabetic complications. Physical activity has various beneficial cardiometabolic effects in type 1 diabetes (T1D) and is associated with lower frequency of chronic complications of diabetes, although the specific mechanisms still remain unclear. The present study determines the association between self-reported physical activity and skin autofluorescence (AF), a marker of tissue accumulation of AGEs in adults with T1D. METHODS: We enrolled 119 patients (63 women), aged 34 years (interquartile range [IQR], 26-41 years), with T1D duration of 17 years (IQR, 12-25 years), glycosylated hemoglobin (HbA1c) of 7.9% (IQR, 7.1%-8.9%) referred to an outpatient diabetes clinic. Patients with diabetes duration of <5 years, age >65 years, concomitant diabetic ketoacidosis, and severe complications that restrict physical activity (eg, diabetic foot, diabetic proliferative retinopathy, blindness) were excluded. Physical activity was measured with the short version of the International Physical Activity Questionnaire (IPAQ-SF), and raw scores were then log-transformed because of non normality. The accumulation of AGEs in the skin was assessed on the basis of skin AF. Correlations between AF and various laboratory and clinical findings were assessed, and multivariate linear regression analysis was used to examine factors that influenced AGEs. FINDINGS: Skin AF correlated positively with age (Spearman's coefficient [Rs] = 0.47; P < 0.0001), HbA1c (Rs = 0.30; P = 0.001), waist-to-hip ratio (WHR; Rs = 0.23; P = 0.02), and negatively with logIPAQ-SF (Rs = -0.28; P = 0.002). A stepwise multivariable linear regression analysis indicated age (beta = 0.46; P < 0.0001), HbA1c (beta = 0.21; P = 0.01), and logIPAQ-SF score (beta = -0.17; P = 0.04) as predictors of the skin AF after adjustment for sex and WHR (R2 = 0.36; P < 0.0001). IMPLICATIONS: Higher physical activity is related to lower accumulation of AGEs in patients with T1D. Our study provides new insight into the beneficial effects of physical activity in T1D according to tissue accumulation of AGEs. PMID- 29567300 TI - Fetal Sex, Need for Insulin, and Perinatal Outcomes in Gestational Diabetes Mellitus: An Observational Cohort Study. AB - PURPOSE: This was a prospective observational cohort study that aimed to determine whether fetal sex influences the maternal and fetal outcomes of gestational diabetes mellitus (GDM). METHODS: In this study, 327 European primiparous women were consecutively recruited after diagnosis of GDM. AUC on the oral glucose tolerance test (OGTT), need for insulin therapy, maternal and obstetrical outcomes, and fetal fat mass (by measuring the thickness of the anterior abdominal subcutaneous tissue) were recorded and compared between the two subgroups of female and male fetuses. FINDINGS: Despite the absence of differences in multiple comparisons of the OGTT, the AUC-OGTT was significantly higher in women carrying a male fetus (22.6 [3.2] mmol/L vs 19.7 [2.8] mmol/L). The abdominal fat thickness appeared to increase with gestational age, with higher growth in male fetuses than in female fetuses. The overall risk of need for insulin therapy was significantly higher in women carrying a male fetus (odds ratio = 1.837). At delivery, birthweight was higher in males than in females only if adjusted for gestational age, similarly for placental weight, otherwise there were no significant differences between the groups in total length of gestation, rates of cesarean delivery, and Apgar scores. IMPLICATIONS: Overall, our data propose an association between fetal sex and GDM outcomes, suggesting the hypothesis that in maternal-fetal interactions, the fetus can affect maternal glucose metabolism.

PMID- 29567302 TI - Synthesis and characterization of CoOx/BiVO4 photocatalysts for the degradation of propyl paraben. AB - Cobalt-promoted bismuth vanadate photocatalysts of variable cobalt content (0-1.0 wt.%) were synthesized and characterized with various techniques including BET, XRD, DRS, XPS and TEM. BiVO4 exists in the monoclinic scheelite structure, while cobalt addition improves the absorbance in the visible region although it does not affect the band gap energy of BiVO4. Cobalt exists in the form of well dispersed Co3O4 nanocrystallites, which are in intimate contact with the much larger BiVO4 nanoparticles. Photocatalytic activity was evaluated for the degradation of propyl paraben (PP) under simulated solar radiation. The activity of pristine BiVO4 is significantly improved adding small amounts of cobalt and is maximized for the catalyst containing 0.5 wt.% Co. PP degradation in ultrapure pure water increases with increasing photocatalyst loading (100 mg/L to 1.5 g/L), and decreasing PP concentration (1600-200 MUg/L). Experiments in bottled water, as well as in pure water spiked with bicarbonate and chloride ions showed little effect of non-target inorganics on degradation. Conversely, degradation is severely impeded in secondary treated wastewater. The enhancement of the photocatalytic activity of the synthesized catalysts is attributed to efficient electron-hole separation, achieved at the p-n junction formed between the p-type Co3O4 and the n-type BiVO4 semiconductors. PMID- 29567303 TI - Photo-Fenton treatment of saccharin in a solar pilot compound parabolic collector: Use of olive mill wastewater as iron chelating agent, preliminary results. AB - The aim of this work was to investigate the treatment of the artificial sweetener saccharin (SAC) in a solar compound parabolic collector pilot plant by means of the photo-Fenton process at pH 2.8. Olive mill wastewater (OMW) was used as iron chelating agent to avoid acidification of water at pH 2.8. For comparative purposes, Ethylenediamine-N, N-disuccinic acid (EDDS), a well-studied iron chelator, was also employed at circumneutral pH. Degradation products formed along treatment were identified by LC-QTOF-MS analysis. Their degradation was associated with toxicity removal, evaluated by monitoring changes in the bioluminescence of Vibrio fischeri bacteria. Results showed that conventional photo-Fenton at pH 2.8 could easily degrade SAC and its intermediates yielding k, apparent reaction rate constant, in the range of 0.64-0.82 L kJ-1, as well as, eliminate effluent's chronic toxicity. Both OMW and EDDS formed iron-complexes able to catalyse H2O2 decomposition and generate HO. OMW yielded lower SAC oxidation rates (k = 0.05-0.1 L kJ-1) than EDDS (k = 2.21-7.88 L kJ-1) possibly due to its higher TOC contribution. However, the degradation rates were improved (k = 0.13 L kJ-1) by increasing OMW dilution in the reactant mixture. All in all, encouraging results were obtained by using OMW as iron chelating agent, thus rendering this approach promising towards the increase of process sustainability. PMID- 29567304 TI - First description of novel arginine catabolic mobile elements (ACMEs) types IV and V harboring a kdp operon in Staphylococcus epidermidis characterized by whole genome sequencing. AB - The arginine catabolic mobile element (ACME) was first described in the methicillin-resistant Staphylococcus aureus strain USA300 and is thought to facilitate survival on skin. To date three distinct ACME types have been characterized comprehensively in S. aureus and/or Staphylococcus epidermidis. Type I harbors the arc and opp3 operons encoding an arginine deaminase pathway and an oligopeptide permease ABC transporter, respectively, type II harbors the arc operon only, and type III harbors the opp3 operon only. To investigate the diversity and detailed genetic organization of ACME, whole genome sequencing (WGS) was performed on 32 ACME-harboring oro-nasal S. epidermidis isolates using MiSeq- and PacBio-based WGS platforms. In nine isolates the ACMEs lacked the opp3 operon, but harbored a complete kdp operon (kdpE/D/A/B/C) located a maximum of 2.8 kb upstream of the arc operon. The kdp operon exhibited 63% DNA sequence identity to the native S. aureus kdp operon. These findings identified a novel, previously undescribed ACME type (designated ACME IV), which could be subtyped (IVa and IVb) based on distinct 5' flanking direct repeat sequences (DRs). Multilocus sequence typing (MLST) sequences extracted from the WGS data identified the sequence types (STs) of the isolates investigated. Four of the nine ACME IV isolates belonged to ST153, and one to ST17, a single locus variant of ST153. A tenth isolate, identified as ST5, harbored another novel ACME type (designated ACME V) containing the kdp, arc and opp3 operons and flanked by DR_F, and DR_B but lacked any internal DRs. ACME V was colocated with a staphylococcal chromosome cassette mec (SCCmec) IV element and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) in a 116.9 kb composite island. The extensive genetic diversity of ACME in S. epidermidis has been further elucidated by WGS, revealing two novel ACME types IV and V for the first time. PMID- 29567305 TI - Novel SCCmec type XIII (9A) identified in an ST152 methicillin-resistant Staphylococcus aureus. AB - We identified a novel staphylococcal cassette chromosome mec (SCCmec) element in an ST152 methicillin-resistant Staphylococcus aureus (MRSA) isolate by combining Illumina and MinION sequencing. The element contains a new ccrC allotype designated ccrC2. The mec complex resembles mec class A, but with an altered organization of the genes. The element was acknowledged as novel by the International Working Group on the Classification of Staphylococcal Cassette Chromosome Elements (IWG-SCC) and designated SCCmec type XIII (9A). PMID- 29567306 TI - Reliability and comparison of Kinect-based methods for estimating spatiotemporal gait parameters of healthy and post-stroke individuals. AB - Different studies have analyzed the potential of the off-the-shelf Microsoft Kinect, in its different versions, to estimate spatiotemporal gait parameters as a portable markerless low-cost alternative to laboratory grade systems. However, variability in populations, measures, and methodologies prevents accurate comparison of the results. The objective of this study was to determine and compare the reliability of the existing Kinect-based methods to estimate spatiotemporal gait parameters in healthy and post-stroke adults. Forty-five healthy individuals and thirty-eight stroke survivors participated in this study. Participants walked five meters at a comfortable speed and their spatiotemporal gait parameters were estimated from the data retrieved by a Kinect v2, using the most common methods in the literature, and by visual inspection of the videotaped performance. Errors between both estimations were computed. For both healthy and post-stroke participants, highest accuracy was obtained when using the speed of the ankles to estimate gait speed (3.6-5.5 cm/s), stride length (2.5-5.5 cm), and stride time (about 45 ms), and when using the distance between the sacrum and the ankles and toes to estimate double support time (about 65 ms) and swing time (60 90 ms). Although the accuracy of these methods is limited, these measures could occasionally complement traditional tools. PMID- 29567307 TI - Development and validation of a subject-specific moving-axis tibiofemoral joint model using MRI and EOS imaging during a quasi-static lunge. AB - The aims of this study were to introduce and validate a novel computationally efficient subject-specific tibiofemoral joint model. Subjects performed a quasi static lunge while micro-dose radiation bi-planar X-rays (EOS Imaging, Paris, France) were captured at roughly 0 degrees , 20 degrees , 45 degrees , 60 degrees , and 90 degrees of tibiofemoral flexion. Joint translations and rotations were extracted from this experimental data through 2D-to-3D bone reconstructions, using an iterative closest point optimization technique, and employed during model calibration and validation. Subject-specific moving-axis and hinge models for comparisons were constructed in the AnyBody Modeling System (AMS) from Magnetic Resonance Imaging (MRI)-extracted anatomical surfaces and compared against the experimental data. The tibiofemoral axis of the hinge model was defined between the epicondyles while the moving-axis model was defined based on two tibiofemoral flexion angles (0 degrees and 90 degrees ) and the articulation modeled such that the tibiofemoral joint axis moved linearly between these two positions as a function of the tibiofemoral flexion. Outside this range, the joint axis was assumed to remain stationary. Overall, the secondary joint kinematics (ML: medial-lateral, AP: anterior-posterior, SI: superior-inferior, IE: internal-external, AA: adduction-abduction) were better approximated by the moving-axis model with mean differences and standard errors of (ML: -1.98 +/- 0.37 mm, AP: 6.50 +/- 0.82 mm, SI: 0.05 +/- 0.20 mm, IE: 0.59 +/- 0.36 degrees , AA: 1.90 +/- 0.79 degrees ) and higher coefficients of determination (R2) for each clinical measure. While the hinge model achieved mean differences and standard errors of (ML: -0.84 +/- 0.45 mm, AP: 10.11 +/- 0.88 mm, SI: 0.66 +/- 0.62 mm, IE: -3.17 +/- 0.86 degrees , AA: 11.60 +/- 1.51 degrees ). PMID- 29567308 TI - Ventricular flow dynamics with varying LVAD inflow cannula lengths: In-silico evaluation in a multiscale model. AB - Left ventricular assist devices are associated with thromboembolic events, which are potentially caused by altered intraventricular flow. Due to patient variability, differences in apical wall thickness affects cannula insertion lengths, potentially promoting unfavourable intraventricular flow patterns which are thought to be correlated to the risk of thrombosis. This study aimed to present a 3D multiscale computational fluid dynamic model of the left ventricle (LV) developed using a commercial software, Ansys, and evaluate the risk of thrombosis with varying inflow cannula insertion lengths in a severely dilated LV. Based on a HeartWare HVAD inflow cannula, insertion lengths of 5, 19, 24 and 50 mm represented cases of apical hypertrophy, typical ranges of apical thicknesses and an experimental length, respectively. The risk of thrombosis was evaluated based on blood washout, residence time, instantaneous blood stagnation and a pulsatility index. By introducing fresh blood to displace pre-existing blood in the LV, after 5 cardiac cycles, 46.7%, 45.7%, 45.1% and 41.8% of pre existing blood remained for insertion lengths of 5, 19, 24 and 50 mm, respectively. Compared to the 50 mm insertion, blood residence time was at least 9%, 7% and 6% higher with the 5, 19 and 24 mm insertion lengths, respectively. No instantaneous stagnation at the apex was observed directly after the E-wave. Pulsatility indices adjacent to the cannula increased with shorter insertion lengths. For the specific scenario studied, a longer insertion length, relative to LV size, may be advantageous to minimise thrombosis by increasing LV washout and reducing blood residence time.

AB - Development of biocompatible nanomaterials with multiple functionalities for combination of radiotherapy and chemotherapy has attracted tremendous attention in cancer treatment. Herein, poly(ethylene glycol) (PEG) modified polydopamine (PDA) nanoparticles were successfully developed as a favorable biocompatible nanoplatform for co-loading antitumor drugs and radionuclides to achieve imaging guided combined radio-chemotherapy. It is demonstrated that PEGylated PDA nanoparticles can effectively load two different drugs including sanguinarine (SAN) and metformin (MET), as well as radionuclides 131I in one system. The loaded SAN and MET could inhibit tumor growth via inducing cell apoptosis and relieving tumor hypoxia, while labeling PDA-PEG with 131I enables in vivo radionuclide imaging and radioisotope therapy. As revealed by the therapeutic efficacy both in cell and animal levels, the multifunctional PDA nanoparticles (131I-PDA-PEG-SAN-MET) can effectively repress the growth of cancer cells in a synergistic manner without significant toxic side effects, exhibiting superior treatment outcome than the respective monotherapy. Therefore, this study provides a promising polymer-based platform to realize imaging-guided radioisotope/chemotherapy combination cancer treatment in future clinical application. PMID- 29567311 TI - Conditional Regulation of Gene Expression by Ligand-Induced Occlusion of a MicroRNA Target Sequence. AB - RNA switches that modulate gene expression with small molecules have a number of scientific and clinical applications. Here, we describe a novel class of small regulatory on switches based on the ability of a ligand-bound aptamer to promote stem formation between a microRNA target sequence (miR-T) and a complementary competing strand. Two on switch architectures employing this basic concept were evaluated, differing in the location of a tetracycline aptamer and the region of a miR-21 target sequence (miR-21-T) masked by its competing strand. Further optimizations of miR-21-T and its competing strand resulted in tetracycline regulated on switches that induced luciferase expression by 19-fold in HeLa cells. A similar switch design based on miR-122-T afforded 7-fold regulation when placed in tandem, indicating that this approach can be extended to additional miR T. Optimized on switches introduced into adeno-associated virus (AAV) vectors afforded 10-fold regulation of two antiviral proteins in AAV-transduced cells. Our data demonstrate that small-molecule-induced occlusion of a miR-T can be used to conditionally regulate gene expression in mammalian cells and suggest that regulatory switches built on this principle can be used to dose expression of an AAV transgene. PMID- 29567312 TI - Preclinical Strategies to Identify Off-Target Toxicity of High-Affinity TCRs. AB - Adoptive transfer of T cells engineered with a cancer-specific T cell receptor (TCR) has demonstrated clinical benefit. However, the risk for off-target toxicity of TCRs remains a concern. Here, we examined the cross-reactive profile of T cell clone (7B5) with a high functional sensitivity for the hematopoietic restricted minor histocompatibility antigen HA-2 in the context of HLA-A*02:01. HA-2pos Epstein-Barr virus-transformed B lymphoblastic cell lines (EBV-LCLs) and primary acute myeloid leukemia samples, but not hematopoietic HA-2neg samples, are effectively recognized. However, we found unexpected off-target recognition of human fibroblasts and keratinocytes not expressing the HA-2 antigen. To uncover the origin of this off-target recognition, we performed an alanine scanning approach, identifying six out of nine positions to be important for peptide recognition. This indicates a low risk for broad cross-reactivity. However, using a combinatorial peptide library scanning approach, we identified a CDH13-derived peptide activating the 7B5 T cell clone. This was confirmed by recognition of CDH13-transduced EBV-LCLs and cell subsets endogenously expressing CDH13, such as proximal tubular epithelial cells. As such, we recommend the use of a combinatorial peptide library scan followed by screening against additional cell subsets to validate TCR specificity and detect off-target toxicity due to cross-reactivity directed against unrelated peptides before selecting candidate TCRs for clinical testing.

PMID- 29567314 TI - Sunlight-induced genotoxicity and damage in keratin structures decrease tadpole performance. AB - The increased incidence of solar ultraviolet (UV) radiation, an environmental genotoxic agent, due to ozone depletion or deforestation may help to explain the enigmatic decline of amphibian populations in specific localities. In this work, we evaluated the importance of DNA repair performed by photolyases to maintain the performance of treefrog tadpoles after acute and chronic treatments with environmental-simulated doses of solar UVB and UVA radiation. Immediately after UV treatments, tadpoles were exposed to a visible light source to activate photolyases or kept in dark containers. The biological effects of UV treatments were evaluated through morphological, histological, locomotor and survival analyzes of Boana pulchella tadpoles (Anura: Hylidae). The results indicate that tadpole body weight suffered influence after both UVB and UVA treatments, although the body length was bit affected. The locomotor performance of UVB exposed tadpoles was significantly reduced. In addition, UVB radiation induced a severe impact on tadpole skin, as well as on keratinized structures of mouth (tooth rows and jaw), indicating that these should be important effects of solar UV radiation in the reduction of tadpole performance. Furthermore, photolyases activation was fundamental for the maintenance of tadpole performance after chronic UVB exposures, but it was relatively inefficient after acute exposures to UVB, but not to UVA radiation. Therefore, this work demonstrates how the UV induced genotoxicity and structural alterations in the skin and oral apparatus affect tadpole performance and survival. PMID- 29567315 TI - A suppository kit for metronomic photodynamic therapy: The elimination of rectal cancer in situ. AB - : Metronomic photodynamic therapy (mPDT) was developed to improve tumor-specific responses through cell death by apoptosis. We developed an mPDT suppository kit including ALA and LED suppositories and analyzed its killing effect on rectal tumors in rabbits. METHODS: The ALA (10 wt%) suppository was prepared using ALA powder, type 36 semi-synthetic fatty acid glyceride, and azone. The LED suppository was constructed by encapsulating LED units and a circuit in transparent epoxy resin. VX2 cells were injected into the rectal submucosa of rabbits to establish a carcinoma model in situ. The ALA suppository was inserted into the rectal cavity for 30 min of uptake and activated for 1 h by the LED suppository at a power density of 20 mW/cm2. The mPDT process was repeated three times once a day. MRI was used to monitor tumor growth, histopathology and TUNEL staining were performed at 14 days after mPDT. RESULTS: The overall response rate was 60% in the mPDT group using the kit in which the tumor size was decreased up to about 50% at 7 days post-mPDT and almost eliminated at 14 days. HE staining showed that only 6.16% of the tumor tissue remained after mPDT treatment. TUNEL detection showed that the apoptosis rate was 18.9%. CONCLUSION: We verified the killing effect of the mPDT suppository kit on rectal tumors in rabbits based on mPDT that induced tumor cell apoptosis. PMID- 29567316 TI - Evaluation of membrane fluidity of multidrug-resistant isolates of Escherichia coli and Staphylococcus aureus in presence and absence of antibiotics. AB - In the face of the serious problem of antimicrobial resistance and the global dissemination of multidrug-resistant (MDR) bacteria, it is relevant to deeply study such bacteria both genetically and phenotypically. It is well known that bacteria have the ability to modify the biophysical properties of their cytoplasmic membranes, namely fluidity, in order to survive and thrive in hostile environments. The aim of this study was to assess and compare the membrane fluidity among multidrug-resistant (MDR) isolates of Escherichia coli and Staphylococcus aureus in absence and in presence of antibiotics (ceftazidime or ciprofloxacin). The membrane fluidity was monitored at 24-h intervals up to three days and at the sixth day, by measuring the anisotropy of 1,6-diphenyl-1,3,5 hexatriene (DPH) and the generalized polarization (GP) of Laurdan (6-dodecanoyl-2 dimethylaminonaphthalene). The anisotropy values as well as the Laurdan excitation GP (GPexc) values obtained from all three E. coli strains (two MDR isolates and one susceptible reference strain) were quite similar and indicative of a very alike membrane phospholipid composition, regardless harboring or not resistance to multiple antimicrobials. Nonetheless, in the case of S. aureus, the anisotropy values were more increased in methicillin-resistant S. aureus (MRSA) isolates in comparison to the reference strain, meaning they have a less fluid membrane. Equally, GPexc values were statistically different among the three S. aureus strains and showed that the two MRSA isolates had more rigid membranes than the susceptible strain. The exposition of MDR isolates of S. aureus to subinhibitory concentrations of ciprofloxacin did not affect neither the anisotropy values nor the GPexc values, therefore, not altering membrane fluidity. Membrane integrity, assessed by the Live/Dead staining, of all strains and conditions studied was maintained over the six days. Thus, these preliminary studies on membrane properties of MDR isolates demonstrate that i) MRSA seem to have a more rigid membrane that susceptible S. aureus and ii) the presence of subinhibitory concentrations of antibiotics does not significantly alter the membrane fluidity of S. aureus, regardless being MDR or susceptible, but slightly affect the membrane fluidity of E. coli.

AB - OBJECTIVE: The aim of this study was to improve the mechanical properties, wear resistance and antibacterial properties of conventional glass ionomer cements (GICs) by fluorinated graphene (FG), under the premise of not influencing their solubility and fluoride ion releasing property. MATERIALS AND METHODS: FG with bright white color was prepared using graphene oxide by a hydrothermal reaction. Experimental modified GICs was prepared by adding FG to the traditional GICs powder with four different weight ratios (0.5wt%, 1wt%, 2wt% and 4wt%) using mechanical blending. Compressive and flexural strength of each experimental and control group materials were investigated using a universal testing machine. The Vickers microhardness of all the specimens was measured by a Vicker microhardness tester. For tribological properties of the composites, specimens of each group were investigated by high-speed reciprocating friction tester. Fluoride ion releasing was measured by fluoride ion selective electrode methods. The antibacterial effect of GICs/FG composites on selected bacteria (Staphylococci aureus and Streptococcus mutans) was tested with pellicle sticking method. RESULTS: The prepared GICs/FG composites with white color were successfully fabricated. Increase of Vickers microhardness and compressive strength and decrease of friction coefficient of the GICs/FG composites were achieved compared to unreinforced materials. The colony count against S. aureus and S. mutans decreased with the increase of the content of FG. And the antibacterial rate of S. mutans can be up to 85.27% when the FG content was 4wt%. Additionally, fluoride ion releasing property and solubility did not show significant differences between unreinforced and FG reinforced GICs. SIGNIFICANCE: Adding FG to traditional GICs could not only improve mechanical and tribological properties of the composites, but also improve their antibacterial properties. In addition, the GICs/FG composites had no negative effect on the color, solubility and fluoride ion releasing properties, which will open up new roads for the application of dental materials.

AB - The Th (T helper) 2 response is characteristic of allergic asthma, and Th17 cells are involved in more severe asthma. Recent studies demonstrated that HMGB1 (High mobility group box 1 protein) regulates airway inflammation and the Th2, Th17 inflammatory response in asthma. HMGB1 can interact with Toll-like receptors (TLR) 2 and 4, and the receptor for advanced glycation end products (RAGE), activating the NF-kappaB (nuclear factor kappa B) signaling pathway and inducing the release of downstream inflammatory mediators. Both Th cells and dendritic cells express TLR2, TLR4, and RAGE receptors. Therefore, we speculate that HMGB1 could regulate the differentiation of Th2, Th17 cells in asthma through direct and indirect mechanisms. An ovalbumin (OVA)-induced mouse asthmatic model was established. Anti-HMGB1 antibody or rHMGB1 was administered to OVA-sensitized mice 30 min prior to each challenge. For in vitro studies, magnetically separated CD4+ naive T cells were stimulated with or without rHMGB1 and/or anti-HMGB1 antibody. BMDCs (bone marrow-derived dendritic cells)-stimulated with or without rHMGB1 and/or anti-HMGB1 antibody were cocultured with CD4+ naive T cells. Our study showed that administration of rHMGB1 aggravated airway inflammation and mucus production, and induced Th2, Th17 polarization in asthmatic mice, and that anti-HMGB1 antibody weakened characteristic features of asthma and blocked the Th2, Th17 inflammatory responses. HMGB1 could directly act on naive T cells to induce differentiation of Th2, Th17 cells in vitro through activating the TLR2, TLR4, RAGE-NF-kappaB signal pathway in CD4+ naive T cells. HMGB1 could also indirectly promote Th2, Th17 differentiation via activating the TLR2, TLR4, RAGE NF-kappaB signal pathway in DCs to mediate their maturation and antigen presenting ability in vitro. PMID- 29567319 TI - In silico design of Mycobacterium tuberculosis epitope ensemble vaccines. AB - Effective control of Mycobacterium tuberculosis is a global necessity. In 2015, tuberculosis (TB) caused more deaths than HIV. Considering the increasing prevalence of multi-drug resistant forms of M. tuberculosis, the need for effective TB vaccines becomes imperative. Currently, the only licensed TB vaccine is Bacillus Calmette-Guerin (BCG). Yet, BCG has many drawbacks limiting its efficacy and applicability. We applied advanced computational procedures to derive a universal TB vaccine and one targeting East Africa. Our approach selects an optimal set of highly conserved, experimentally validated epitopes, with high projected population coverage (PPC). Through rigorous data analysis, five different potential vaccine combinations were selected each with PPC above 80% for East Africa and above 90% for the World. Two potential vaccines only contained CD8+ epitopes, while the others included both CD4+ and CD8+ epitopes. Our prime vaccine candidate was a putative seven-epitope ensemble comprising: SRGWSLIKSVRLGNA, KPRIITLTMNPALDI, AAHKGLMNIALAISA, FPAGGSTGSL, MLLAVTVSL, QSSFYSDW and KMRCGAPRY, with a 97.4% global PPC and a 92.7% East African PPC. PMID- 29567320 TI - Ultrasound-guided coracohumeral ligament release. AB - Long-term follow-up of patients with adhesive capsulitis (AC) reveals that approximately half of them suffer from a limited range of shoulder motion, particularly external and/or internal rotation. We report the surgical technique and short-term clinical outcomes of ultrasound-guided release of the thickened coracohumeral (CH) ligament in 8 patients (9 shoulders) with AC. Passive external rotation with the arm by the side significantly increased from an average of 18 degrees preoperatively to 47 degrees immediately after CH ligament release. VAS and ASES scores were improved at 3months follow-up in all 9 shoulders, and maintained at 6months follow-up in 6 shoulders. No procedure-related adverse events developed over the 6-month follow-up period. Ultrasound-guided release for thickened CH ligament is a reliable and effective minimally invasive surgery for persistent limited external rotation due to AC of the shoulder. PMID- 29567321 TI - Effect of early fasting and total parenteral nutrition support on the healing of incision and nutritional status in patients after sacrectomy. AB - INTRODUCTION: Surgical site infection is one of the most common complications for patients after sacrectomy, which often accompanied by poor wound healing, sinus formation and serious metabolic disturbance. HYPOTHESIS: We tried to avoid the surgical site infection caused by feces during early period after surgery through early fasting and total parenteral nutrition (TPN) support, then compared the clinical results of these patients with other patients that received enteral nutrition (EN) early after sacrectomy. METHODS: Forty-eight patients after sacrectomy (the level of sacrectomy above S2) were randomly divided into two groups: TPN group and EN group. The patients of two groups received different nutrition support from the first day to the seventh day after surgery, then the factors such as nutritional and metabolic status after surgery, incidence of complications as well as the time of incision healing and hospitalization were observed. RESULTS: The p-value of total serum protein, albumin, serum alanine aminotransferase, total bilirubin at seventh day after sacrectomy between TPN group and EN group is <0.0005. The p-value of hemoglobin at seventh day after sacrectomy between TPN group and EN group is 0.001. The p-value of total serum protein at fourteenth day after sacrectomy between TPN group and EN group is 0.003. The p-value of albumin and total bilirubin at fourteenth day after sacrectomy between TPN group and EN group is 0.001. The p-value of hemoglobin, serum alanine aminotransferase at fourteenth day after sacrectomy between TPN group and EN group is <0.0005. The incidence of gastrointestinal complication and delay of apparition of feces in EN group were lower than that in TPN group (p=0.041, p<0.0005). The incidence of surgical site infection, the time of incision healing and hospitalization in TPN group were lower than that in EN group (p=0.048, p=0.008, p<0.0005). CONCLUSIONS: The method of fasting and supported by TPN during the early period after sacrectomy contribute to the incision healing, meanwhile, it shortens the hospitalization time and abates the incidence of complications in patients after sacrectomy. TYPE OF STUDY: It is a comparative randomized study. LEVEL OF PROOF: High-powered prospective randomized trial. PMID- 29567322 TI - Collection and reconstruction after harvesting donor tissues from the musculoskeletal system: Technique specific to the lower limbs. AB - The lack of available musculoskeletal grafts in France forces us to import a very large quantity of these tissues to use in complex reconstruction procedures. The goal of this article is to describe methods for collecting donor tissues from the musculoskeletal system and for reconstructing the harvested areas. We also provide a summary of the collection procedures performed, harvested grafts and available tissues. While tissue collection requires a significant time investment, the emergence of dedicated teams may be a solution for increasing the number and quality of human musculoskeletal allograft tissues. PMID- 29567323 TI - Circular RNA (circRNA) was an important bridge in the switch from the RNA world to the DNA world. AB - The concept that life on Earth began as an RNA world has been built upon extensive experimentation demonstrating that many of the building blocks required for living cells could be synthesized in the laboratory under conditions approximating our primordial world. Many of the building blocks for life have also been found in meteorites indicating that meteors may have been a source for these molecules, or more likely, that they represent the chemical library present in most/all bodies in the universe after the big bang. Perhaps the most important support for the concept comes from the fact that some RNA species possess catalytic activity, ribozymes, and that RNA could be reverse transcribe to DNA. The thrust of numerous papers on this topic has been to explore how the available molecules on Earth, at its birth, gave rise to life as we know it today. This paper focuses more on a reverse view of the topic. The "how" molecular building blocks were synthesized is not addressed nor how the "first" RNA molecules were synthesized. We can clearly speculate on the variable environmental conditions and chemistry available on Earth billions of years ago. However, we can never truly replicate the changing conditions or know the chemical composition of Earth at the beginning of time. We can, however, confirm that over millions, perhaps billions of years the basic building blocks for life accumulated sufficiently to initiate evolution to an RNA world followed by our RNA/DNA world. Here we are attempting to take the information from our current knowledge of biology and by inference and extrapolation work backward to hypothesize biological events in the march forward from RNA to DNA. It is proposed that the primordial replicating RNA cell, the ribocyte, evolved from liposomes encompassing required reactants and products for "life" and that ribonucleopeptide complexes formed membrane pores to support bidirectional ion and molecular transport to maintain biological functions and osmolarity. Circular RNA, circRNA, is proposed as a critical stable RNA molecule that served as the genetic precursor for the switch to DNA and the replication of circRNA by a rolling circle mechanism gave rise to the RNA complexity required for the genetic functions of the cell. The replicating ribocyte would have required protein synthesis as well as RNA replication and a model for non-coded and primordial coded protein synthesis is proposed. Finally, the switch from the RNA to the DNA world would have involved the synthesis of an RNA:DNA hybrid prior to the formation of dsDNA. If the hybrid was a circular molecule that ultimately yielded a circular dsDNA molecule, it could predict that the primordial DNA cell would evolve into a bacterial cell with a single circular chromosome. One would hope that continued speculation of the origin of life will spur new directions of research that may never fully answer the questions of the past but add to our ability to regulate potentially harmful biological events in the present and in the future. PMID- 29567324 TI - Multiplicity of phenotypes and RNA evolution. AB - Motivation Motoo Kimura's neutral theory stipulates that evolution is predominantly driven by neutral mutations. RNA, realizing both genotype (its linear sequence of nucleotides) as well as phenotype (its folded secondary structure) represents a particularly well suited test bed for studying neutrality. This leads to neutral networks of RNA secondary structures, i.e. sets of sequences all of which folding into a fixed phenotype and whose organization plays a crucial role for neutral evolution. In this paper we bring a new perspective to the neutral theory by studying the consequences of the mostly ignored fact that the genotype-to-phenotype map for RNA is often one-to-many. In fact 29.5% of random RNA sequences realize more than one phenotype (minimum free energy structure). We call two genotypes to be quasineutral if their sets of associated phenotypes have non-empty intersection. Results We show that even though the energy profile of quasineutral mutations is almost identical to the neutral ones, a walk in the genotype space whose consecutive steps are quasineutral, can percolate phenotype space and so such walks bridge between neutral and random walks. This provides further evidence that evolution is continuous. We also study how these drift walks transition between neutral networks. PMID- 29567325 TI - Mate sampling influences the intensity of sexual selection and the evolution of costly sexual ornaments. AB - Mate choice includes three steps: (1) a choosing individual encounters potential mates, (2) assesses and processes information about them, and (3) makes a mate decision. During mate searching females can access only a sample of males in the mating pool and need to choose their mates based on limited information. Thus, mate sampling may influence sexual selection promoted by mate choice because it constrains female choice. Using individual-based simulations, we found that both female choosiness and mate sampling influenced the variance in mating success among males and thus the intensity of sexual selection. So that sexual selection is most intense when females are strongly choosy and can sample many males. Moreover, in evolutionary simulations, the rate of evolutionary change and the final size of male ornament increase with increasing mate sampling. However, under stronger natural selection, evolutionary change is slower and leads to smaller ornaments. Empirical data on the potential for sexual selection (Is) for several animal species show a positive correlation between the intensity of sexual selection and an index of mate sampling based on behavioral and ecological traits. Based on the results of our simulations, we predict that males of highly mobile species with long-range sexual signal transmission, which allow females to assess many males, will show greater variance in mating success and will be more ornamented than their relatives not exhibiting these features. PMID- 29567326 TI - Lysine Deacetylases and Regulated Glycolysis in Macrophages. AB - Regulated cellular metabolism has emerged as a fundamental process controlling macrophage functions, but there is still much to uncover about the precise signaling mechanisms involved. Lysine acetylation regulates the activity, stability, and/or localization of metabolic enzymes, as well as inflammatory responses, in macrophages. Two protein families, the classical zinc-dependent histone deacetylases (HDACs) and the NAD-dependent HDACs (sirtuins, SIRTs), mediate lysine deacetylation. We describe here mechanisms by which classical HDACs and SIRTs directly regulate specific glycolytic enzymes, as well as evidence that links these protein deacetylases to the regulation of glycolysis related genes. In these contexts, we discuss HDACs and SIRTs as key control points for regulating immunometabolism and inflammatory outputs from macrophages. PMID- 29567327 TI - Origin and Immunological Functions of Spleen Stromal Cells. AB - The mammalian spleen is a peripheral lymphoid organ that plays a central role in host defense. Consequently, the lack of spleen is often associated with immunodeficiency and increased risk of overwhelming infections. Growing evidence suggests that non-hematopoietic stromal cells are central players in spleen development, organization, and immune functions. In addition to its immunological role, the spleen also provides a site for extramedullary hematopoiesis (EMH) in response to injuries. A deeper understanding of the biology of stromal cells is therefore essential to fully comprehend how these cells modulate the immune system during normal and pathological conditions. Here, we review the specificities of the different mouse spleen stromal cell subsets and complement the murine studies with human data when available. PMID- 29567328 TI - Literature-based safety assessment of an agriculture- and animal-associated microorganism: Weissella confusa. AB - Although Weissella confusa was established as a species over 25 years ago, it has been understudied until very recently. Several independent observations have driven the recent interest in this important microorganism. First, this Leuconostoc-like species of Lactic Acid Bacteria is associated with agricultural environments, many spontaneous food fermentations-especially carbohydrate-rich vegetable fermentations-and silage. Second, Weissella confusa are members of the autochthonous microbiota of healthy humans and livestock. Third, Weissella confusa-in a strain-specific fashion-are postulated to be good candidates for the development of novel direct-fed microbial products. Fourth, Weissella confusa-in a strain-specific fashion-have been described as opportunistic pathogens especially in immunocompromised individuals. Last, a distantly related species (Weissella ceti) is the etiologic agent of weissellosis, a disease that affects farmed fish that are important for commercial aquaculture. The purpose of this literature-based safety assessment is to consolidate findings from primary research related to Weissella confusa and its natural associations with and effects on animals, humans, and their agricultural environments. Based on these assessments, it is reasonable to conclude that many Weissella confusa are safe for use in direct-fed microbial products for poultry. PMID- 29567329 TI - Acute and repeated dose 28-day oral toxicity of poly(3-hydroxybutyrate-co-4 hydroxybutyrate) nanoparticles in Sprague-Dawley rats. AB - This study aimed to investigate the oral acute and subacute toxicity of Poly [3 hydroxybutyrate-co-4-hydroxybutyrate], P(3HB-co-4HB) in the form of nanoparticles in Sprague-Dawley rats. Acute oral administration of P(3HB-co-4HB) nanoparticles was performed as a single dose up to 2000 mg/kg in six female rats for 14 days. Subacute toxicity study via oral administration for 28 days at doses of 0 (control), 500, 1000 and 2000 mg/kg in rats (10 rats in each group, female:male = 1:1) was conducted. The estimated lethal dose (LD50) of P(3HB-co-4HB) nanoparticles was >2000 mg/kg. No mortality, unusual changes in behaviour, adverse clinical signs, abnormal changes in body weights or food consumption were observed on all animals treated with P(3HB-co-4HB) nanoparticles during 14 days of the acute toxicity study. In the subacute test, there was no mortality and toxicologically significant changes in clinical signs, body weights, food consumption, hematology, clinical biochemistry, urinalysis, macroscopic findings, organ weights as well as histopathological examination were observed. PMID- 29567330 TI - Dietary supplement intake during pregnancy; better safe than sorry? AB - Consumption of dietary supplements and specifically niche products such as supplements targeting pregnant women is increasing. The advantages of dietary supplementation during pregnancy with folic acid have been established, but health effects of many other supplements have not been confirmed. EU and US legislation on dietary supplements requires the product to be safe for the direct consumer, the mother. Long-term health effects for the fetus due to fetal programming (in utero adaptation of the fetal epigenome due to environmental stimuli such as supplementation) are not taken into account. Such epigenetic alterations can, however, influence the response to health challenges in adulthood. We therefore call for both conducting research in birth cohorts and animal studies to identify potential health effects in progeny of supplement consuming mothers as well as the establishment of a nutrivigilance scheme to identify favorable and adverse effects post-marketing. The acquired knowledge can be used to create more effective legislation on dietary supplement intake during pregnancy for safety of the child. Increasing knowledge on the effects of consuming supplements will create a safer environment for future mothers and their offspring to optimize their health before, during and after pregnancy. PMID- 29567331 TI - An evaluation of electronic cigarette formulations and aerosols for harmful and potentially harmful constituents (HPHCs) typically derived from combustion. AB - U.S. FDA draft guidance recommends reporting quantities of designated harmful and potentially harmful constituents (HPHCs) in e-cigarette e-liquids and aerosols. The HPHC list comprises potential matrix-related compounds, flavors, nicotine, tobacco-related impurities, leachables, thermal degradation products, and combustion-related compounds. E-cigarettes contain trace levels of many of these constituents due to tobacco-derived nicotine and thermal degradation. However, combustion-related HPHCs are not likely to be found due to the relatively low operating temperatures of most e-cigarettes. The purpose of this work was to use highly sensitive, selective, and validated analytical methods to determine if these combustion-related HPHCs (three aromatic amines, five volatile organic compounds, and the polycyclic aromatic hydrocarbon benzo[a]pyrene) are detectable in commercial refill e-liquids, reference e-cigarette e-liquids, and aerosols generated from rechargeable e-cigarettes with disposable cartridges (often referred to as "cig-a-likes"). In addition, the transfer efficiency of these constituents from e-liquid to aerosol was evaluated when these HPHCs were added to the e-liquids prior to aerosol formation. This work demonstrates that combustion-related HPHCs are not present at measurable levels in the commercial and reference e-liquids or e-cigarette aerosols tested. Additionally, when combustion-related HPHCs are added to the e-liquids, they transfer to the aerosol with transfer efficiencies ranging from 49% to 99%. PMID- 29567332 TI - miR-486-5p functions as an oncogene by targeting PTEN in non-small cell lung cancer. AB - PURPOSE: Lung cancer, the leading cause of cancer-related death worldwide, shows a poor 5-year overall survival rate. In our previous study, we demonstrated that miR-486-5p can be a potential blood-based biomarker for early diagnosis and recurrence prediction of non-small cell lung cancer (NSCLC). The aim of the present study was to investigate the possible roles and related target genes of miR-486-5p in NSCLC progression. METHODS: pcDNA3.1(+)/Pri-miR486 recombinant plasmid and miR-486-5p inhibitor were transfected into NSCLC cells and theirs effects were evaluated by qRT-PCR. Then, MTT assay and Colony formation assay were performed to determine the potential roles of miR-486-5p played on NSCLC cellular proliferation and cloning in vitro. We also initially investigated the target genes of miR-486-5p by using bioinformatic methods, qRT-PCR and western blot. RESULTS: pcDNA3.1(+)/Pri-miR486 recombinant plasmid significantly upregulated the expression of miR-486-5p, while miR-486-5p inhibitor significantly downregulated its expression. Upregulation of miR-486-5p promoted the cellular proliferation and cloning, while miR-486-5p silencing restrained the cellular proliferation and cloning. Furthermore, four potential target genes (PIK3R1, PTEN, MAP3K7 and FOXO1) of miR-486-5p were screened out. Finally, we found that upregulation of miR-486-5p in NSCLC cells significantly reduced PTEN and increased AKT expression levels, whereas miR-486-5p silencing increased PTEN and reduced AKT expression. Therefore, we believe that miR-486-5p can regulate PTEN-PI3 K/AKT signaling. CONCLUSIONS: miR-486-5p acts as an oncogene in the progression of NSCLC by influencing PTEN-PI3 K/AKT signaling. miR-486-5p may provide potential therapeutic targets for NSCLC. PMID- 29567333 TI - Chinese herb medicine matrine induce apoptosis in human esophageal squamous cancer KYSE-150 cells through increasing reactive oxygen species and inhibiting mitochondrial function. AB - Matrine, as a natural alkaloid isolated from the traditional herb medicine sophora flavescens, has been proved to possess excellent biological activities, including anticancer effects. Now, this research aims to assess the anticancer activities and the mechanism of matrine against esophageal cancer cells, we investigated the proliferative inhibition, apoptosis induction, as well as the underlying mechanism of matrine on esophageal cancer KYSE-150 cells. It was found that matrine could suppress KYSE-150 cell proliferation and significantly mediate cell apoptosis in a dose-dependent relation by increasing intracellular reactive oxygen species level and triggering mitochondrial membrane potential disruption. More precise mechanism studies demonstrated that matrine could up-regulate the expression of Bax proteins and down-regulate the expression of Bcl-2 proteins, as well as the activation about caspase-3, 8 and 9 in KYSE-150 cells. The morphological analysis of KYSE-150 cells exhibited that matrine could destroy the F-actin and nuclei structures and induce morphological damage with increased surface height distribution and roughness of cell membrane. These results not only demonstrated the potential anticancer activity mechanism of matrine at nanoscale, but also provide preliminary guidance for the treatment of esophageal cancer using matrine. PMID- 29567334 TI - Multicenter phase I/II study of chemoradiotherapy with high-dose CDDP for head and neck squamous cell carcinoma in Japan. AB - OBJECTIVE: Recent data indicated that concurrent chemoradiotherapy (CCRT) using high dose cisplatin (CDDP) is the most useful treatment for advanced head and neck squamous cell carcinoma (SCC). Regarding the dose of CDDP, 100mg/m2 is most recommended in Western countries. However, in terms of a balance of efficacy and adverse events, appropriate dose of cytotoxic drugs such as CDDP may be different among the different ethnic groups. In this multicenter phase I/II study, we aimed to identify the optimal dose of CDDP in CCRT for patients with advanced head and neck SCC in the Japanese. METHODS: Patients were eligible for inclusion if they had head and neck SCC that was treated with radical CCRT comprising whole-neck irradiation of the primary lesion and level II-IV lymph nodes on both sides. For the phase I study, a CDDP dose was 70mg/m2 for level 0, 80mg/m2 for level 1, and 100mg/m2 for level 2. Maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) were examined by phase I trial, by which CDDP dose for phase II was determined. The primary endpoint for the phase II was CCRT completion rate, and the secondary endpoint was full-dose-CCRT completion rate, the percentage of patients receiving a total CDDP dose of >=200mg/m2, response rate, and incidences of adverse events. RESULTS: A CDDP dose of 100mg/m2 was the MTD for phase I, and the recommended dose for phase II was 80 mg/m2. Forty-seven patients were evaluated in the phase II trial. CCRT completion rate, full-dose-CCRT rate, and the percentage of patients receiving a total CDDP dose of >=200mg/m2, were 93.6%, 78.7%, and 93.6%, respectively. One patient (2.1%) developed grade 2 renal dysfunction, and no patient developed febrile neutropenia or a grade 4 adverse event. CONCLUSION: The present phase I study indicated that a CDDP dose of 80mg/m2 is the optimal dose in terms of safety. The phase II study revealed that CCRT completion rate, response rate, and rates of adverse events were not inferior for a CDDP dose of 80mg/m2 as compared with a dose of 100mg/m2, and a dose of 80mg/m2 is therefore recommended in CCRT for the Japanese. This study was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; identification No. UMIN000010369). PMID- 29567335 TI - Effect of family nursing therapeutic conversations on health-related quality of life, self-care and depression among outpatients with heart failure: A randomized multi-centre trial. AB - OBJECTIVE: To evaluate the short-term (3 months) effects of family nursing therapeutic conversations (FNTC) on health-related quality of life, self-care and depression in outpatients with Heart failure (HF). METHODS: A randomised multi centre trial was conducted in three Danish HF clinics. The control group (n = 167) received usual care, and the intervention group (n = 180) received FNTCs as supplement to usual care. Primary outcome was clinically significant changes (6 points) in Kansas City Cardiomyopathy Questionnaire (KCCQ) summary score between groups. Secondary outcomes were changes in self-care behaviour and depression scores. Data were assessed before first consultation and repeated after three months. RESULTS: No statistically significant difference was found in the change of KCCQ, self-care and depression scores between the groups. KCCQ scores of patients in the FNTC group changed clinically significant in seven domains, compared to one domain in the control group, with the highest improvement in self efficacy, social limitation and symptom burden. CONCLUSION: FNTC was not superior to standard care of patients with HF regarding health-related quality of life, self-care and depression. IMPLICATION FOR PRACTICE: Addressing the impact of the disease on the family, might improve self-efficacy, social limitation and symptom burden in patients with heart failure. PMID- 29567337 TI - Biomarkers of glomerular dysfunction in pre-eclampsia - A systematic review. AB - BACKGROUND: Early detection of pre-eclampsia remains one of the major focuses of antenatal obstetric care. There is often a delay in the diagnosis, mainly due to the non-specific nature of the condition. Podocytes which play a pivotal role in glomerular function become injured in pre-eclampsia leading to subsequent proteinuria. Our aim was to review available studies to determine the clinical utility of biomarkers of podocyte injury in pre-eclampsia. METHODS: We used QUADAS (Quality Assessment of Diagnostic Accuracy Studies) criteria to perform a systematic review of the literature to determine the clinical utility of podocyte injury biomarkers in predicting pre-eclampsia. RESULTS: This study identified five potential renal biomarkers including podocytes, nephrin, synaptopodin, podocin and podocalyxin. The pooled sensitivity of all biomarkers was 0.78 (95% CI 0.74-0.82) with a specificity of 0.82 (95% CI 0.79-0.85). The area under the Summary of Receiver Operating Characteristics Curve (SROC) was 0.926 (SE 0.30). Urinary nephrin achieved the highest diagnostic values with a sensitivity of 0.81 (95% CI 0.72-0.88) and specificity of 0.84 (95% CI 0.79-0.84). CONCLUSION: Biomarkers of glomerular injury show promise as diagnostic aids in pre-eclampsia. A large-scale prospective cohort study is warranted before these biomarkers can be recommended for routine clinical care. PMID- 29567338 TI - Novel piperidine-derived amide sEH inhibitors as mediators of lipid metabolism with improved stability. AB - We have previously identified and reported several potent piperidine-derived amide inhibitors of the human soluble epoxide hydrolase (sEH) enzyme. The inhibition of this enzyme leads to elevated levels of epoxyeicosatrienoic acids (EETs), which are known to possess anti-inflammatory, vasodilatory, and anti fibrotic effects. Herein, we report the synthesis of 9 analogs of the lead sEH inhibitor and the follow-up structure-activity relationship and liver microsome stability studies. Our findings show that isosteric modifications that lead to significant alterations in the steric and electronic properties at a specific position in the molecule can reduce the efficacy by up to 75-fold. On the other hand, substituting hydrogen with deuterium produces a notable increase (~30%) in the molecules' half-lives in both rat and human microsomes, while maintaining sEH inhibition potency. These data highlight the utility of isosteric replacement for improving bioavailability, and the newly-synthesized inhibitor structures may thus, serve as a starting point for preclinical development. Our docking study reveals that in the catalytic pocket of sEH, these analogs are in proximity of the key amino acids involved in hydrolysis of EETs. PMID- 29567336 TI - Cis- and Trans-Modifiers of Repeat Expansions: Blending Model Systems with Human Genetics. AB - Over 30 hereditary diseases are caused by the expansion of microsatellite repeats. The length of the expandable repeat is the main hereditary determinant of these disorders. They are also affected by numerous genomic variants that are either nearby (cis) or physically separated from (trans) the repetitive locus, which we review here. These genetic variants have largely been elucidated in model systems using gene knockouts, while a few have been directly observed as single-nucleotide polymorphisms (SNPs) in patients. There is a notable disconnect between these two bodies of knowledge: knockouts poorly approximate the SNP-level variation in human populations that gives rise to medically relevant cis- and trans-modifiers, while the rarity of these diseases limits the statistical power of SNP-based analysis in humans. We propose that high-throughput SNP-based screening in model systems could become a useful approach to quickly identify and characterize modifiers of clinical relevance for patients.

AB - Surgical treatment of gastro-esophageal reflux disease (ST-GERD) is well-codified and offers an alternative to long-term medical treatment with a better efficacy for short and long-term outcomes. However, failure of ST-GERD is observed in 2 20% of patients; management is challenging and not standardized. The aim of this study is to analyze the causes of failure and to provide a treatment algorithm. The clinical aspects of ST-GERD failure are variable including persistent reflux, dysphagia or permanent discomfort leading to an important degradation of the quality of life. A morphological and functional pre-therapeutic evaluation is necessary to: (i) determine whether the symptoms are due to recurrence of reflux or to an error in initial indication and (ii) to understand the cause of the failure. The most frequent causes of failure of ST-GERD include errors in the initial indication, which often only need medical treatment, and surgical technical errors, for which surgical redo surgery can be difficult. Multidisciplinary management is necessary in order to offer the best-adapted treatment. PMID- 29567341 TI - A pilot study assessing retinal pathology in psychosis using optical coherence tomography: Choroidal and macular thickness. AB - Mounting evidence supports a genetic-vascular-inflammatory etiology of schizophrenia. The retina provides an indirect assessment of inflammation and degeneration in the brain. In particular, the use of spectral domain optical coherence tomography (SD-OCT) has emerged as a powerful tool for examining single retinal nerve cell layers and the choroid, the vascular layer supplying the outer retina. In this study, choroidal and macular thicknesses were measured in six patients with psychosis with either schizophrenia or bipolar disorder, and in 18 age- and sex-matched healthy controls. Mean choroidal thickness was reduced in psychosis, though not significantly so. There was a statistically significant decrease in macular thickness in psychosis patients predominantly affecting the inner layers of the macula. Significant macular thinning may signal vascular, inflammatory, or degenerative processes that may also be occurring in the brain. This is one of the first studies to examine choroidal thickness in psychosis. Further studies are needed to determine whether the retinal changes in psychosis are correlated with microvascular dysfunction, neuroinflammation, and neurodegeneration.

AB - PURPOSE: To evaluate the biomechanical performance of a commercially available bridging plate (2.4) as well as screws and bone simulating the reconstruction of hemimandibular defects and to indicate alternatives of reinforcement to prevent plate fractures either by strength or fatigue. MATERIAL AND METHODS: Two common hemimandibular defects are investigated using computed finite element analysis (FEA) approach. Simplified and refined computational models are developed for the geometry of the screw. Conditions of non-locking and locking plate-screw interfaces are considered. Static loads of 120 N are applied. Von Mises stresses and fatigue are calculated. As reinforcement, a second complete or partial plate is placed onto the original plate. RESULTS: Results demonstrate that reconstruction plates are often subjected to excessive stress that may lead to fracture either by strength or by fatigue. An attached complete or partial second plate is able to reduce stress in the plate, in screws and bone so that stress remains below the allowable limit of the materials. CONCLUSION: A simplified technique of attaching a whole or sectioned second plate onto the original plate can reduce the stress calculated and may reduce the frequency of plate fractures for the patient's comfort, security and financial savings. PMID- 29567340 TI - Country-Level Macroeconomic Indicators Predict Early Post-Allogeneic Hematopoietic Cell Transplantation Survival in Acute Lymphoblastic Leukemia: A CIBMTR Analysis. AB - For patients with acute lymphoblastic leukemia (ALL), allogeneic hematopoietic cell transplantation (alloHCT) offers a potential cure. Life-threatening complications can arise from alloHCT that require the application of sophisticated health care delivery. The impact of country-level economic conditions on post-transplantation outcomes is not known. Our objective was to assess whether these variables were associated with outcomes for patients transplanted for ALL. Using data from the Center for Blood and Marrow Transplant Research, we included 11,261 patients who received a first alloHCT for ALL from 303 centers across 38 countries between the years of 2005 and 2013. Cox regression models were constructed using the following macroeconomic indicators as main effects: Gross national income per capita, health expenditure per capita, and Human Development Index (HDI). The outcome was overall survival at 100 days following transplantation. In each model, transplants performed within lower resourced environments were associated with inferior overall survival. In the model with the HDI as the main effect, transplants performed in the lowest HDI quartile (n = 697) were associated with increased hazard for mortality (hazard ratio, 2.42; 95% confidence interval, 1.64 to 3.57; P < .001) in comparison with transplants performed in the countries with the highest HDI quartile. This translated into an 11% survival difference at 100 days (77% for lowest HDI quartile versus 88% for all other quartiles). Country-level macroeconomic indices were associated with lower survival at 100 days after alloHCT for ALL. The reasons for this disparity require further investigation. PMID- 29567343 TI - Value of PET/CT 3D visualization of head and neck squamous cell carcinoma extended to mandible. AB - PURPOSE: To study an original 3D visualization of head and neck squamous cell carcinoma extending to the mandible by using [18F]-NaF PET/CT and [18F]-FDG PET/CT imaging along with a new innovative FDG and NaF image analysis using dedicated software. The main interest of the 3D evaluation is to have a better visualization of bone extension in such cancers and that could also avoid unsatisfying surgical treatment later on. PATIENTS AND METHODS: A prospective study was carried out from November 2016 to September 2017. Twenty patients with head and neck squamous cell carcinoma extending to the mandible (stage 4 in the UICC classification) underwent [18F]-NaF and [18F]-FDG PET/CT. We compared the delineation of 3D quantification obtained with [18F]-NaF and [18F]-FDG PET/CT. In order to carry out this comparison, a method of visualisation and quantification of PET images was developed. This new approach was based on a process of quantification of radioactive activity within the mandibular bone that objectively defined the significant limits of this activity on PET images and on a 3D visualization. Furthermore, the spatial limits obtained by analysis of the PET/CT 3D images were compared to those obtained by histopathological examination of mandibular resection which confirmed intraosseous extension to the mandible. RESULTS: The [18F]-NaF PET/CT imaging confirmed the mandibular extension in 85% of cases and was not shown in [18F]-FDG PET/CT imaging. The [18F]-NaF PET/CT was significantly more accurate than [18F]-FDG PET/CT in 3D assessment of intraosseous extension of head and neck squamous cell carcinoma. This new 3D information shows the importance in the imaging approach of cancers. All cases of mandibular extension suspected on [18F]-NaF PET/CT imaging were confirmed based on histopathological results as a reference. CONCLUSIONS: The [18F]-NaF PET/CT 3D visualization should be included in the pre-treatment workups of head and neck cancers. With the use of a dedicated software which enables objective delineation of radioactive activity within the bone, it gives a very encouraging results. The [18F]-FDG PET/CT appears insufficient to confirm mandibular extension. This new 3D simulation management is expected to avoid under treatment of patients with intraosseous mandibular extension of head and neck cancers. However, there is also a need for a further study that will compare the interest of PET/CT and PET/MRI in this indication. PMID- 29567344 TI - Enantiomeric neolignans from Picrasma quassioides exhibit distinctive cytotoxicity on hepatic carcinoma cells through ROS generation and apoptosis induction. AB - Three pairs of enantiomeric neolignans 1a/1b-3a/3b were isolated from the stems of Picrasma quassioides, and separated successfully by chiral-phase HPLC. Their structures were established by comprehensive spectroscopic analyses as well as ECD spectroscopy. The in vitro cytotoxicity of the isolates was evaluated against human hepatocellular carcinoma HepG2 and Hep3B cells. Among them, 1 and its enantiomers 1a/1b, 3 and 3a/3b displayed similar cytotoxicity in pair-wise comparison against HepG2 and Hep3B cells, and the similar effects of 2 and 2a/2b were found in Hep3B cells. Interestingly, 2a and 2b had different cytotoxic activities on HepG2 cells with IC50 values of 35.6 MUM and 104.4 MUM, respectively. In addition, 2 exerted middle cytotoxicity against HepG2 cells with an IC50 value of 78.6 MUM. The different cytotoxicity between enantiomers 2a and 2b attracted our interest. To investigate the underlying mechanisms responsible for the distinct cytotoxicity, we further assessed the effects of 2a and 2b on cell cycle distribution, cell apoptosis and reactive oxygen species (ROS) generation. The results indicated that 2a had more significant effect than 2b on apoptosis induction and ROS generation, but both had no obvious effect on cell cycle of HepG2 cells. It is concluded that the different configurations of 2a/2b determined the enantioselective cytotoxicity on HepG2 cells through apoptosis induction and ROS generation. PMID- 29567345 TI - Evaluation of analogues of furan-amidines as inhibitors of NQO2. AB - Inhibitors of the enzyme NQO2 (NRH: quinone oxidoreductase 2) are of potential use in cancer chemotherapy and malaria. We have previously reported that non symmetrical furan amidines are potent inhibitors of NQO2 and here novel analogues are evaluated. The furan ring has been changed to other heterocycles (imidazole, N-methylimidazole, oxazole, thiophene) and the amidine group has been replaced with imidate, reversed amidine, N-arylamide and amidoxime to probe NQO2 activity, improve solubility and decrease basicity of the lead furan amidine. All compounds were fully characterised spectroscopically and the structure of the unexpected product N-hydroxy-4-(5-methyl-4-phenylfuran-2-yl)benzamidine was established by X ray crystallography. The analogues were evaluated for inhibition of NQO2, which showed lower activity than the lead furan amidine. The observed structure activity relationship for the furan-amidine series with NQO2 was rationalized by preliminary molecular docking and binding mode analysis. In addition, the oxazole amidine analogue inhibited the growth of Plasmodium falciparum with an IC50 value of 0.3 MUM.

PMID- 29567347 TI - Extrapolation of the Hepatic Clearance of Drugs in the Absence of Albumin In Vitro to That in the Presence of Albumin In Vivo: Comparative Assessement of 2 Extrapolation Models Based on the Albumin-Mediated Hepatic Uptake Theory and Limitations and Mechanistic Insights. AB - The extrapolation of hepatic clearance (CL) from data determined in an in vitro assay in the absence of albumin (ALB) to that in the presence of ALB in liver in vivo was often inaccurate using traditional in vitro-to-in vivo extrapolation (IVIVE) methods for drugs binding to the ALB. It is recognized that considering an ALB-facilitated hepatic uptake phenomenon in the IVIVE can improve the extrapolation. Therefore, the present study provides a comparison of 2 existing models that account for the ALB-facilitated hepatic uptake phenomenon in the IVIVE of CL. These models assume an interaction of the ALB-bound drug complex with the hepatocyte membrane that enhanced the dissociation of the drug from ALB to result in increased unbound intracellular drug levels available for metabolism or transporter-mediated elimination. One model refers to the old facilitated dissociation model (FDM), which is based on a binding isotherm and necessitates knowing the specific input parameters of the interaction (i.e., relative capacity of the interaction, dissociation constant, number of binding sites, and ALB concentration). The other model is based on the same theory but is recent and more speculative although it presumes that each interaction between the ALB-drug complex and the hepatocyte surface would at all times enhance and deliver the dissociated bound drug moiety into the hepatocytes and therefore, has the advantage to use less binding information. Consequently, this second model simply consists of adjusting the unbound fraction determined in plasma in vitro of each drug (fup-adjusted) with the real differential of ALB concentration between the plasma and liver in vivo to estimate the corresponding differential of ALB-drug complex also assumed available to deliver the unbound drug moiety for hepatic uptake in vivo versus in vitro. Application of these 2 models (FDM and fup adjusted) significantly improved the IVIVEs of CL of drugs, and hence, the next step was to compare these 2 models with the same data set. Recently published data on the hepatic uptake of 2 organic anions, namely 1-anilino-8-naphthalene sulfonate and pitavastatin, provide all binding information. As expected, the results indicate that these 2 models are conceptually and mathematically equivalent as well as they successfully predicted the experimentally determined ratios of the unbound intrinsic CL (CLint) in the presence of ALB in vivo to that in the absence of ALB in vitro. However, the 2 models were equivalent particularly for pitavastatin because its ALB-drug complex showed a relevant capacity of interaction and dissociation with the hepatocyte membrane. Conversely, for 1-anilino-8-naphthalene sulfonate, the model of fup-adjusted overestimated the ratio of unbound CLint by contrast to the FDM model because its ALB-drug complex demonstrated a significantly lower capacity of interaction with the membrane. The rational is simply because the model of fup-adjusted presumably assumed an important facilitated-uptake phenomenon for each drug, whereas the FDM model was derived from binding data specific to each drug. Overall, these 2 models are complementary, and all contribute toward achieving the same objective of quantifying the ALB-facilitated uptake phenomenon; however, the FDM model is more specific, but its application necessitates collecting more binding data compared with the model of fup-adjusted that can be used prospectively to predict the maximal effect of the facilitated-hepatic uptake in IVIVE. PMID- 29567348 TI - Transport and sorting in the Golgi complex: multiple mechanisms sort diverse cargo. AB - At the center of the secretory pathway, the Golgi complex ensures correct processing and sorting of cargos toward their final destination. Cargos are diverse in topology, function and destination. A remarkable feature of the Golgi complex is its ability to sort and process these diverse cargos destined for secretion, the cell surface, the lysosome, or retained within the secretory pathway. Just as these cargos are diverse so also are their sorting requirements and thus, their trafficking route. There is no one-size-fits-all sorting scheme in the Golgi. We propose a coexistence of models to reconcile these diverse needs. We review examples of differential sorting mediated by proteins and lipids. Additionally, we highlight recent technological developments that have potential to uncover new modes of transport. PMID- 29567349 TI - Whole exome sequencing discloses a pathogenic MTM1 gene mutation and ends the diagnostic odyssey in an older woman with a progressive and seemingly sporadic myopathy: Case report and literature review of MTM1 manifesting female carriers. AB - We report the case of a 58-year-old woman with a progressive and seemingly sporadic myopathy who, later through whole exome sequencing, was diagnosed as a manifesting carrier of a myotubularin 1 gene mutation (c.342_342 + 4delAGTAA). As the case was a diagnostic challenge for 7 years, we thought it would be helpful to report the patient and review the other 25 cases thus far described. The manifesting carrier state is a rare cause for myopathic weakness in a female but should be strongly considered in kindreds with known affected males with myotubularin 1 gene mutations, and families with history of gestational polyhydramnios or male infantile death. Although the clinical phenotype is quite variable, the findings of ptosis, ophthalmoparesis, facial weakness, and asymmetrical limb involvement should raise the suspicion of the manifesting carrier state. Necklace fibers appear to be a highly sensitive and specific pathologic finding in such cases. PMID- 29567350 TI - Progressive fat replacement of muscle contributes to the disease mechanism of patients with single, large-scale deletions of mitochondrial DNA. AB - Muscle dysfunction in mitochondrial myopathy is predominantly caused by insufficient generation of energy. We hypothesise that structural changes in muscles could also contribute to their pathophysiology. The aims of this study were to determine fat fractions and strength in selected muscles in patients with chronic progressive external ophthalmoplegia (CPEO), and compare progression of muscle fat fraction with age in individuals with CPEO vs. healthy controls and patients with the m.3243A>G mutation of mitochondrial DNA (mtDNA). Seventeen patients with CPEO and single large-scale deletions of mtDNA, 52 healthy controls, and 12 patients carrying the m.3243A>G mtDNA mutation were included. Muscle fat fractions were measured from cross-sections of paraspinal and leg muscles. Peak muscle strength was assessed from a static dynamometer. There was a direct correlation between age and fat fraction in all muscle groups in CPEO patients and healthy controls (p < 0.05). Analysis of covariance showed a higher progression rate of fat replacement in CPEO patients vs. healthy controls in studied muscle groups (p < 0.05). Patients with the m.3243A>G mutation had slower progression rates of fat replacement. Muscle strength decreased with increasing muscular fat fraction in CPEO patients, no correlation was seen in other groups. This indicates that structural muscle changes contribute to the phenotype of older patients affected by CPEO and large-scale deletions. It should therefore be considered, along with known energy deficiencies, as the cause of exercise intolerance. PMID- 29567351 TI - Interatrial block to predict atrial fibrillation in myotonic dystrophy type 1. AB - Paroxysmal atrial fibrillation frequently occurs in Myotonic dystrophy type 1 (DM1) patients. Interatrial block is recognized as predictor of atrial arrhythmias, particularly atrial fibrillation (AF). The aim of this study was to evaluate the role of interatrial block in predicting the onset of atrial fibrillation during 2-year follow-up in DM1 patients who underwent pacemaker implantation for conduction system disorders. The study prospectively enrolled 70 DM1 patients (aged 36-69; 31 M) who underwent pacemaker implantation for cardiac rhythm abnormalities in accordance with the current guidelines. All DM1 patients underwent 12-lead surface ECG, 2D color Doppler echocardiogram and device interrogation at implantation, one month after and every six months thereafter for a minimum of 2-year follow-up. 12-lead surface ECGs were analyzed to diagnose interatrial block (IAB), defined as a P-wave duration >=120 ms without (partial IAB) or with (advanced IAB) biphasic morphology (+/-) in the inferior leads. Device interrogation was performed to evaluate the development of new onset atrial high rate electrograms compatible with paroxysmal atrial fibrillation episodes. Interatrial block was detected in 22 patients (31.4%): 18 partial (25.7%) and 4 advanced (5.7%). During follow-up, AF episodes were detected in 18 DM1 patients (25.7%). The study population was divided into 2 groups according to the presence of AF (AF+ Group vs AF- Group). The AF+ Group was older and showed higher prevalence of IAB than the AF- Group. IAB was found to be independent predictor of AF in DM1 population (P < 0.001). A cut-off value of 121 ms for IAB had a sensitivity of 83.3% and specificity of 90.3% in identifying DM1 patients at high risk of developing AF. Interatrial block represents an independent predictor of AF occurrence in our DM1 population with conduction disturbances who had previously undergone pacemaker implantation. PMID- 29567352 TI - Mechanical forces in skin disorders. AB - Mechanical forces are known to regulate homeostasis of the skin and play a role in the pathogenesis of skin diseases. The epidermis consists of keratinocytes that are tightly adhered to each other by cell junctions. Defects in keratins or desmosomal/hemidesmosomal proteins lead to the attenuation of mechanical strength and formation of intraepidermal blisters in the case of epidermolysis bullosa simplex. The dermis is rich in extracellular matrix, especially collagen, and provides the majority of tensile force in the skin. Keloid and hypertrophic scar, which is the result of over-production of collagen by fibroblasts during the wound healing, are associated with extrinsic tensile forces and changes of intrinsic mechanical properties of the cell. Increasing evidences shows that stiffness of the skin environment determines the regenerative ability during wound healing process. Mechanotransduction pathways are also involved in the morphogenesis and cyclic growth of hair follicles. The development of androgenetic alopecia is correlated to tensile forces generated by the fibrous tissue underlying the scalp. Acral melanoma predominantly occurs in the weight bearing area of the foot suggesting the role of mechanical stress. Increased dermal stiffness from fibrosis might be the cause of recessive dystrophic epidermolysis bullosa associated squamous cell carcinoma. Strategies to change the mechanical forces or modify the mechanotransduction signals may lead to a new way to treat skin diseases and promote skin regeneration. PMID- 29567353 TI - Proton pumping by cytochrome c oxidase - A 40 year anniversary. AB - Cytochrome c oxidase is a remarkable energy transducer that seems to work almost purely by Coulombic principles without the need for significant protein conformational changes. In recent years it has become possible to follow key partial reactions of the catalytic cycle in real time, both with respect to electron and proton movements. These experiments have largely set the stage for the proton pump mechanism. The structures of the catalytic binuclear heme-copper site that is common to the huge family of heme-copper oxidases, are today well understood throughout the catalytic cycle of oxygen reduction to water based on both spectroscopic studies and quantum chemical calculations. Here, we briefly review this progress, and add some recent details into how the proton pump mechanism is protected from failure by leakage. PMID- 29567355 TI - Hepatitis B vaccine nonresponders: Possible mechanisms and solutions. AB - OBJECTIVE: Hepatitis B (HBV) is a viral illness that chronically infects 240 million people worldwide, leads to liver disease, and increases risk of hepatocellular carcinoma. The HBV vaccine has decreased HBV infection, and it and the human papilloma virus vaccine are the only vaccines that prevent cancer. Despite the effectiveness of the HBV vaccine, some populations do not develop protective responses. The risk groups for poor response include those with immunosuppression or dialysis-dependent, end-stage renal disease. Five percent of normal people do not have a response. These subjects are deemed HBV "nonresponders." Multiple strategies to improve the immunogenicity of the HBV vaccine are currently being pursued, including vaccine adjuvants, recombinant vaccines, and immune enhancement via up-regulation of dendritic cells. DATA SOURCES: PubMed was searched for peer-reviewed publications published from January 1980 to September 2017. STUDY SELECTIONS: Studies retrieved for inclusion summarized potential mechanisms behind HBV vaccine nonresponsiveness and potential solutions. RESULTS: The mechanisms behind HBV vaccine nonresponsiveness vary between each subject population. Many current and future strategies may provide protective immunity against HBV in each of these populations. CONCLUSION: This review provides a background on the immunology of HBV infection, the possible immunologic mechanisms to explain HBV vaccine nonresponsiveness, current research aimed at improving vaccine effectiveness, and possible future approaches for providing nonresponders protection from HBV. PMID- 29567354 TI - Consequences of cytochrome c oxidase assembly defects for the yeast stationary phase. AB - The assembly of cytochrome c oxidase (COX) is essential for a functional mitochondrial respiratory chain, although the consequences of a loss of assembled COX at yeast stationary phase, an excellent model for terminally differentiated cells in humans, remain largely unexamined. In this study, we show that a wild type respiratory competent yeast strain at stationary phase is characterized by a decreased oxidative capacity, as seen by a reduction in the amount of assembled COX and by a decrease in protein levels of several COX assembly factors. In contrast, loss of assembled COX results in the decreased abundance of many mitochondrial proteins at stationary phase, which is likely due to decreased membrane potential and changes in mitophagy. In addition to an altered mitochondrial proteome, COX assembly mutants display unexpected changes in markers of cellular oxidative stress at stationary phase. Our results suggest that mitochondria may not be a major source of reactive oxygen species at stationary phase in cells lacking an intact respiratory chain.

PMID- 29567357 TI - Self-reported adverse reactions associated with mycoprotein (Quorn-brand) containing foods. AB - BACKGROUND: Mycoprotein, which is produced by a mold and is the basis of Quorn brand meat substitutes, is a novel cause of allergic and gastrointestinal reactions, but little information has been available on its associated symptomatology. OBJECTIVE: To describe the nature and frequency of adverse reactions to mycoprotein. METHODS: Self-reports of adverse reactions to mycoprotein were collected via a Web-based questionnaire (www.quorncomplaints.org) and then analyzed. RESULTS: Analysis of 1,752 adverse reactions found that Quorn products caused allergic and gastrointestinal symptoms, with some people experiencing both. Allergic reactions, including urticaria and anaphylaxis, occurred within 4 hours of consumption in 312 people. Of those reactions, 45.8%, 1 fatal, began within 1 hour of exposure. Of those 312 individuals, 188 (60.3%) reported repeated reactions after repeated consumption of Quorn, and 2 people experienced 8 reactions (13 people did not say whether they experienced more than 1 reaction). Quorn foods caused gastrointestinal symptoms, including emesis and diarrhea, within 8 hours of consumption in 1,692 people. Of the gastrointestinal symptoms, 66.6% occurred 46 to 180 minutes after consumption of the products. Symptoms ranged from mild nausea to emesis severe enough to warrant medical attention. CONCLUSION: Mycoprotein may be causing numerous and sometimes life-threatening allergic and gastrointestinal reactions. The acceptance in the food supply of this nonessential ingredient deserves reconsideration. PMID- 29567358 TI - Effect of short-term liver X receptor activation on epidermal barrier features in mild to moderate atopic dermatitis: A randomized controlled trial. AB - BACKGROUND: Liver X receptors (LXRs) are involved in maintaining epidermal barrier and suppressing inflammatory responses in model systems. The LXR agonist VTP-38543 showed promising results in improving barrier function and inflammatory responses in model systems. OBJECTIVE: To assess the safety, tolerability, cellular and molecular changes, and clinical efficacy of the topical VTP-38543 in adults with mild to moderate atopic dermatitis (AD). METHODS: A total of 104 ambulatory patients with mild to moderate AD were enrolled in this randomized, double-blind, vehicle-controlled trial between December 2015 and September 2016. VTP-38543 cream in 3 concentrations (0.05%, 0.15%, and 1.0%) or placebo was applied twice daily for 28 days. Pretreatment and posttreatment skin biopsy specimens were obtained from a subset of 33 patients. Changes in SCORing of Atopic Dermatitis, Eczema Area and Severity Index, Investigator's Global Assessment, and tissue biomarkers (by real-time polymerase chain reaction and immunostaining) were evaluated. RESULTS: Topical VTP-38543 was safe and well tolerated. VTP-38543 significantly increased messenger RNA (mRNA) expression of epidermal barrier differentiation (loricrin and filaggrin, P = .02) and lipid (adenosine triphosphate-binding cassette subfamily G member 1 and sterol regulatory element binding protein 1c, P < .01) measures and reduced epidermal hyperplasia markers (thickness, keratin 16 mRNA). VTP-38543 nonsignificantly suppressed cellular infiltrates and down-regulated mRNA expression of several TH17/TH22-related (phosphatidylinositol 3, S100 calcium-binding protein A12) and innate immunity (interleukin 6) markers. CONCLUSION: Topical VTP-38543 is safe and well tolerated. Its application led to improvement in barrier differentiation and lipids. Longer-term studies are needed to clarify whether a barrier-based approach can induce meaningful suppression of immune abnormalities. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02655679. PMID- 29567359 TI - Validity and responsiveness of the Urticaria Activity and Impact Measure: A new patient-reported tool. AB - BACKGROUND: Chronic spontaneous urticaria (CSU), also known as chronic idiopathic urticaria, may produce hives, itch, and angioedema. The Urticaria Activity and Impact Measure (U-AIM) is a newly developed 9-item patient-reported measure designed for use in routine clinical practice to assess CSU activity and impact during the previous 7 days. OBJECTIVE: To evaluate validity, responsiveness, and clinically meaningful change of the U-AIM. METHODS: Data from a 24-week, open label, single-arm period of a randomized, placebo-controlled study of omalizumab were used to assess the psychometric properties of U-AIM items for itch, hives, and angioedema. RESULTS: A total of 206 patients (75% female; mean age, 44.6 years) were enrolled. At baseline, U-AIM results included prevalent severe itch (55%) and more than 12 hives (67%), angioedema (15%), and bother by itch (84%), hives (84%), and angioedema (49%). The Urticaria Patient Daily Diary (UPDD) mean weekly scores were 15.4 (itch severity), 16.8 (number of hives), and 32.2 (Urticaria Activity Score [UAS7]). At baseline, week 12, and week 24, U-AIM itch and hives items and UAS7 proxy scores (the sum of itch severity and number of hives during 7 days) demonstrated strong correlation coefficients with their corresponding measures from the UPDD (itch severity: 0.634-0.806; hives number: 0.735-0.843; UAS7 proxy: 0.724-0.852). Changes in U-AIM scores differentiated patients by their perspective of symptom improvement. Meaningful change thresholds were established for itch severity and number of hives scores (range, 0.8-1.0 for both) and the UAS7 proxy score (range, 10.5-12.5). CONCLUSION: The U AIM is valid and responsive to change and may help clinicians monitor CSU activity and track treatment effectiveness. PMID- 29567360 TI - Gastrointestinal metastasis from primary lung cancer. Case series and systematic literature review. AB - Aim of the present study is to report clinical characteristics and outcomes of patients treated in authors' hospital for GI metastasis from primary lung cancer, and to report and analyse the same data concerning patients retrieved from a systematic literature review. We performed a retrospective analysis of prospectively collected data, and a systematic review using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. Ninety-one patients were included, 5 patients from the authors' hospital and 86 through PubMed database using the keywords "intestinal metastasis" AND "lung cancer". The median time between primary lung cancer diagnosis and GI metastasis diagnosis was 2 months and the median overall survival was 4 months. This group of patients present a poor prognosis and the gold standard treatment is not defined. None of the reported treatments had a significant impact on survival.

PMID- 29567362 TI - BRAF V600E mutation in papillary thyroid cancer and its effect on postoperative radioiodine (131I) therapy: Should we modify our therapeutic strategy? AB - INTRODUCTION: The BRAF V600E mutation in papillary thyroid cancer (PTC) has been associated with resistance to 131I. Our aim was to quantify the response to 131I after surgery in patients who had the mutation (BRAF+) and those who did not have the mutated gene (BRAF-). METHOD: A prospective cohort study was designed, from September 2015 to February 2016, which included patients with PTC receiving therapy after surgical treatment. Variables were described for age, gender, histology, tumor stage, thyroglobulin values before, 48h after and 6months after 131I; absorbed dose and % activity on days 2 and 7 and elimination time. RESULTS: 41 patients giving in total 67 thyroid remnants were included. 61% were BRAF+. In stagesiii and iv, 80% were BRAF+. In lateral resection, 100% were BRAF+. The number of nodes was higher in BRAF+: 3.4 vs 1.2 (P=.01). The classic variant was predominant in BRAF+ (91.7% vs 8.3%, P=.03). 85.7% vs 14.3% of BRAF+ had desmoplastic reaction (P=.02). The BRAF+ had a lower absorbed dose than the administered activity (5.4Gy/MBq vs 20Gy/MBq, P=.02); lower% activity with respect to the unit of mass at 2 (0.046%/g vs 0.103%/g, P=.02) and at 7days (0.006%/gr vs 0.034%/gr, P=.04) CONCLUSIONS: The mutation of the BRAF V600E gene is related with greater resistance to postoperative treatment with 131I since the onset of the disease.

AB - The performance of seven sub-2-MUm particle packed columns (2-picolylamine, 2 PIC; charged surface hybrid fluoro-phenyl, CSH-FP; high strength silica C18 SB, HSS-C18; diethylamine, DEA; 1-aminoanthracene, 1-AA; high density diol and ethylene bridged hybrid; BEH) was examined for lipid separation in ultra-high performance supercritical fluid chromatography (UHPSFC) coupled to quadrupole time-of-flight mass spectrometry. Based on the results of the column screening a method for profiling of multiple lipid species from the major lipid classes was developed. Stationary phases containing beta-hydroxy amines, i.e. 1-AA, DEA and 2 PIC, yielded strong retention and poor peak shapes of zwitterionic lipids with primary amine groups, such as phosphatidylserines, phosphatidylethanolamines and its lyso forms. The BEH and HSS-C18 columns showed strong retention of polar and nonpolar lipids, respectively. The Diol column retained the majority of major lipid classes and also produced symmetric peaks. In addition, this column also produced the highest resolution within and between major lipid classes. An injection solvent composed of methanol:chloroform (1:2, v:v) and the addition of 20 mM ammonium formate in the mobile phase improved chromatographic separation and mass spectrometry detection in comparison to ammonium acetate or absence of additive. Finally, chromatographic and mass spectrometric parameters were optimized for the Diol column using a design of experiments approach. The separation mechanism on the Diol column depended on the lipid functionality and the length and degree of unsaturation of the acyl groups. The developed method could resolve 18 lipid classes and multiple lipids within each class, from blood serum and brain tissue in 11 min.

AB - Urocanic acid (UA), existing in trans- or cis-isoform, is of fairly recent interest to food researchers because of its potential public health hazards of scombrotoxicity and immunotoxicity, as well as associating with fish spoilage. This work is among the first efforts to study the analytical chemistry of UA in fish. With 0.6 M perchloric acid UA was extracted, and co-extracted fish matrix components were efficiently removed through a reactive extraction of UA. The optimum conditions for the reactive extraction, which allowed an 80% recovery of UA, were sample pH adjustment to 9, twice extractions with 32% (w/w) di (2 ethylhexyl) phosphate in hexanol, and a back-extraction with 0.1 M hydrochloric acid at 1:1 phase ratio. A chaotropic hexafluorophosphate salt was added to acidic water-acetonitrile mobile phases to improve the reversed-phase chromatography of UA, which otherwise was poorly retained. Optimum separation conditions were obtained for fish samples and enabled a fast (10 min), convenient to-use chromatography that clearly outperforms cumbersome legacy ion-pair chromatography. Intended for routine use in our laboratory, the proposed method passed an in-house validation test for linearity, matrix effect (on reactive extraction), accuracy, precision, and detectability. PMID- 29567365 TI - Enzyme assay for d-amino acid oxidase using optically gated capillary electrophoresis-laser induced fluorescence detection. AB - Because d-amino acids (AAs) play an essential role in the regulation of many processes in living cells, detection of D-AAs and assay of d-amino acid oxidase (DAAO) activity are of vital importance in bioanalytical science. However, the reliability and accuracy of DAAO assays could be interfered due to the facts that DAAO presents broad substrate activity towards different D-AAs and there could be abundant L-AA enantiomers in biological samples. In this study we presented the first application of optically gated capillary electrophoresis with LIF detection (OGCE-LIF) for efficient assay of DAAO activity. High repeatability of the OGCE LIF assay of amino acids (AAs) was achieved with relative standard deviation (RSD) (n = 15) less than 1.5% and 2.7% for migration time and peak height, respectively. Under the optimal OGCE-LIF conditions, five pairs of D/L-AA enantiomers were efficiently separated in less than 1 min with low limit of detection of 1.3 MUM. Enzymatic assays of DAAO were successfully achieved by detection the substrate consumption with OGCE-LIF, for either single or mixed AA substrates. Kinetic analysis of the parallel oxidation reactions of two different substrates was performed, which was in good agreement with the experimental results. Our study indicates OGCE-LIF can perform rapid and efficient separation of mixed pairs of AA enantiomers and is a promising method for quantitatively assaying DAAO catalyzed reaction with the presence of L-AA enantiomers in the sample. Our study would pave the way for accurate determination of D-AAs and DAAO enzymes in complicated biological samples. PMID- 29567366 TI - Reversed phase ion-pair chromatographic separation of sugar alcohols by complexation with molybdate ion. AB - In this study, we developed a simple and sensitive reversed phase ion-pair chromatographic method for the analysis of C4-C6 sugar alcohols. The method is based on the on-line complexation of sugar alcohols with molybdate ion. The resulting dinuclear anionic complexes can be separated on a reversed-phase C18 column using tetrabutylammonium chloride as an ion-pairing reagent. The mobile phase (pH 3.1) consisted of 0.1 mM disodium molybdate, 1 mM hydrochloric acid and 0.4 mM tetrabutylammonium chloride - 10% v/v methanol. By complexing with molybdate ion, sugar alcohols can be detected by their UV absorption at 247 nm with high resolution and sensitivity. The quantification limits of the examined sugar alcohols calculated at S/N = 10 were 0.1 mM for erythritol and xylitol and 0.01 mM for arabitol, sorbitol, mannitol and dulcitol. The detector response was linear over three orders of magnitude of sugar alcohol concentration. The proposed method was successfully applied to measure sugar alcohols in health drinks, eyedrops and mouthwashes. PMID- 29567367 TI - With a simple calculation, the fraction of platelets remaining can be used to estimate the residual hemoglobin S percentage in sickle cell disease patients undergoing automated red blood cell exchange. AB - OBJECTIVES: Automated red blood cell exchange (RBX) is an important treatment for patients with sickle cell disease (SCD). Although not specifically targeted for removal, platelets (PLTs) are collected along with red blood cells during RBX. We sought to determine whether the pre- and post- RBX PLT counts could be used to derive the post-procedure hemoglobin S% (HgbS%). METHODS: Using the pre- and post RBX lab values of 59 SCD patients undergoing 112 RBX procedures over 1 year, we derived mathematical formulas which estimate the post-RBX HgbS% based on the pre RBX HgbS%, the pre- and post- RBX PLT, and a correction factor. RESULTS: For patients with pre-RBX HgbS > 40%, the mathematically derived post-RBX HgbS% was statistically indistinguishable from the measured post-RBX HgbS%. CONCLUSIONS: Using a simple formula, pre- and post-RBX platelet counts can provide a rapid approximation of the measured post-RBX HgbS% in patients with SCD. PMID- 29567368 TI - Efficacy of eculizumab in severe ADAMTS13-deficient thrombotic thrombocytopenic purpura (TTP) refractory to standard therapies. AB - Thrombotic thrombocytopenic purpura (TTP) is a rare microangiopathic hemolytic anemia (MAHA) defined by mechanical hemolytic anemia, severe thrombocytopenia, and systemic visceral ischemia due to systemic platelet-rich microthrombi. Forty percent of patients with autoimmune TTP experience one or multiple relapses. Patients with refractory TTP are currently managed by corticosteroids, twice daily PEX, and the anti-CD20 monoclonal antibody rituximab. Herein, we report two cases of severe TTP, refractory to those standard agents. On the basis of the fact that in cases of severe TTP the classical complement pathway is activated, and that the alternative pathway is also involved, both patients underwent eculizumab (anti-C5 monoclonal antibody) therapy. We observed prompt hematological and organ system responses to the eculizumab and the recovery of plasma ADAMTS-13 activity in both cases. Moreover, the fact that both patients discontinued eculizumab, maintaining the response, emphasizes the possibility of its usefulness for limited treatment periods. In conclusion, the diagnostic and therapeutic algorithm in TTP appears complicated by increasing evidence of complement involvement and the eculizumab seems to be a potential agent for refractory patients.

AB - To battle adverse internal and external conditions and maintain homeostasis, diploid organisms employ various cellular processes, such as proliferation and apoptosis. In some tissues, an alternative mechanism, endoreplication, is employed toward similar goals. Endoreplication is an evolutionarily conserved cell cycle program during which cells replicate their genomes without division, resulting in polyploid cells. Importantly, endoreplication is reported to be indispensable for normal development and organ formation across various organisms, from fungi to humans. In recent years, more attention has been drawn to delineating its connections to wound healing and tumorigenesis. In this Review, we discuss mechanisms of endoreplication and polyploidization, their essential and positive roles in normal development and tissue homeostasis, and the relationship between polyploidy and cancer. PMID- 29567372 TI - A six-microRNA signature predicts survival of patients with uterine corpus endometrial carcinoma. AB - Uterine corpus endometrial carcinoma (UCEC) is one of the most common female gynecological malignant tumors that threaten women health seriously. MicroRNAs (miRNAs) has been proved to play critical roles in tumor pathogenesis and malignant progression. In this study, we aimed to explore a novel signature of microRNA expression for predicting the overall survival (OS) of patients with UCEC. The genome-wide miRNA expression profiles and relevant clinical characteristics of 348 patients with UCEC were downloaded from the Cancer Genome Atlas (TCGA) data portal and analyzed comprehensively. A total of 144 miRNAs were confirmed to be expressed differentially in tumor tissues. Among them, 6 miRNAs (hsa-mir-15a.MIMAT0000068, hsa-mir-142.MIMAT0000433, hsa-mir-142.MIMAT0000434, hsa-mir-3170.MIMAT0015045, hsa-mir-1976.MIMAT0009451, and hsa-mir 146a.MIMAT0000449) were validated to be significantly correlated with the OS of patients with UCEC. The risk indictor established by the 6-microRNA signature was proved be an independent prognostic factor (Hazard ratio = 0.391; 95% CI: 0.195 0.783; P = 0.008). In conclusion, we identified miRNAs that were correlated with the occurrence and progression of UCEC and established a 6-microRNA expression signature as a predictor for the OS of patients with UCEC. PMID- 29567371 TI - A pilot study on immuno-psychiatry in the 22q11.2 deletion syndrome: A role for Th17 cells in psychosis? AB - BACKGROUND: A growing body of evidence supports a role for immune alterations in Schizophrenia Spectrum Disorders (SSD). A high prevalence (25-40%) of SSD has been found in patients with 22q11.2 deletion syndrome (22q11.2DS), which is known for T-cell deficits due to thymus hypoplasia. This study is the first to explore the association between the T-cell subsets and psychotic symptoms in adults with 22q11.2DS. METHODS: 34 individuals (aged 19-38 yrs.) with 22q11.2DS and 34 healthy age- and gender matched control individuals were included. FACS analysis of the blood samples was performed to define T-cell subsets. Ultra-high risk for psychosis or diagnosis of SSD was determined based on CAARMS interviews and DSM-5 criteria for SSD. Positive psychotic symptom severity was measured based on the PANSS positive symptoms subscale. RESULTS: A partial T-cell immune deficiency in 22q11.2DS patients was confirmed by significantly reduced percentages of circulating T and T-helper cells. Significantly higher percentages of inflammatory Th1, Th17, and memory T-helper cells were found in adults with 22q11.2DS. Most importantly an increased Th17 percentage was found in adults with psychotic symptoms as compared to non-psychotic adults with 22q11.2DS, and Th17 percentage were related to the presence of positive psychotic symptoms. CONCLUSIONS: Given the literature on the role of T cells and in particular of Th17 cells and IL-17 in hippocampus development, cognition and behavior, these results support the hypothesis for a role of Th17 cells in the development and/or regulation of psychotic symptoms in 22q11.2DS. This pilot study underlines the importance to further study the role of T-cell defects and of Th17 cells in the development of psychiatric symptoms. It also supports the possibility to use 22q11.2DS as a model to study T-cell involvement in the development of SSD. PMID- 29567373 TI - Synthesis of novel laccase-biotitania biocatalysts for malachite green decolorization. AB - Biomimetic mineralization has emerged as a novel tool for generating excellent supports for enzyme stabilization. In this work, protamine was used to induce titanium (IV) bis(ammonium lactato) dihydroxide (Ti-BALDH) into titania nanoparticles. This biomimetic titanification process was adopted for laccase immobilization. Laccase-biotitania biocatalyst was prepared and the effect of different parameters (buffer solution, titania precursor concentration, protamine concentration, and enzyme loading) on the encapsulation efficiency and recovery of laccase were evaluated. Compared with free laccase, the thermal and pH stability of immobilized laccase were improved significantly. In addition, laccase loaded on titania was effective at enhancing its storage stability. After seven consecutive cycles, the immobilized laccase still retained 51% of its original activity. Finally, laccase-biotitania biocatalysts showed good performance on decolorization of malachite green (MG), which can be attributed to an adsorption and degradation effect. The intermediates of the MG degradation were identified by gas chromatography-mass spectrometry (GC-MS) analysis, and the most probable degradation pathway was proposed. This study provides deeper understanding of the laccase-biotitania particles as a fast biocatalyst for MG decolorization. PMID- 29567374 TI - Risk assessment of methylmercury based on internal exposure and fish and seafood consumption estimates in Taiwanese children. AB - Fish and seafood consumption is a major source of human exposure to methylmercury (MeHg). This study evaluated the potential health risk of MeHg in Taiwanese children from fish and seafood consumption using a toxicokinetic model, hazard quotients and hazard indices (HIs). Two biomonitoring programs provided an important resource for blood specimens for assessing MeHg exposure in human populations. For internal exposures, total mercury (THg) was measured as a biomarker of MeHg in whole blood (WB) and red blood cells using inductively coupled plasma mass spectrometry and cold-vapor atomic absorption spectroscopy, respectively. The THg concentrations were used to estimate MeHg concentrations. Consumption of fish and seafood was assessed using the National Food Consumption database in Taiwan, while mercury concentrations in edible fish and seafood were collected from published studies in Taiwan. Our results indicated that 1) the highest median THg (representing estimated MeHg) daily intakes were found to decrease with increasing age in children consuming saltwater fish for age groups 0-3, 4-6, 7-12, and 13-18 years: 0.03 > 0.02 > 0.017 > 0.007 (MUg kg-BW-1 day-1); 2) HI greater than one, based on WB-THg, was found in 28% of 4-6-year-old children and 3) internal exposure estimates based on WB-THg, though slightly higher, were comparable to those based on fish and seafood consumption. The results support the use of dietary intake estimates as surrogates for internal blood MeHg levels in Taiwanese children to assess their exposure. PMID- 29567375 TI - On the use of total aerobic spore bacteria to make treatment decisions due to Cryptosporidium risk at public water system wells. AB - Spore reduction can be used as a surrogate measure of Cryptosporidium natural filtration efficiency. Estimates of log10 (log) reduction were derived from spore measurements in paired surface and well water samples in Casper Wyoming and Kearney Nebraska. We found that these data were suitable for testing the hypothesis (H0) that the average reduction at each site was 2 log or less, using a one-sided Student's t-test. After establishing data quality objectives for the test (expressed as tolerable Type I and Type II error rates), we evaluated the test's performance as a function of the (a) true log reduction, (b) number of paired samples assayed and (c) variance of observed log reductions. We found that 36 paired spore samples are sufficient to achieve the objectives over a wide range of variance, including the variances observed in the two data sets. We also explored the feasibility of using smaller numbers of paired spore samples to supplement bioparticle counts for screening purposes in alluvial aquifers, to differentiate wells with large volume surface water induced recharge from wells with negligible surface water induced recharge. With key assumptions, we propose a normal statistical test of the same hypothesis (H0), but with different performance objectives. As few as six paired spore samples appear adequate as a screening metric to supplement bioparticle counts to differentiate wells in alluvial aquifers with large volume surface water induced recharge. For the case when all available information (including failure to reject H0 based on the limited paired spore data) leads to the conclusion that wells have large surface water induced recharge, we recommend further evaluation using additional paired biweekly spore samples.

AB - This study aimed (1) to evaluate the in vitro post-warming survival of porcine embryos after re-vitrification and (2) to assess the efficacy of transport of embryos in dry shipper (DS) in maintaining the viability and quality of vitrified embryos for a 3-day period. Embryos at the compacted or cavitating morula (CCM) and unhatched blastocyst (UBL) stages were surgically obtained from weaned, crossbred sows. In the first experiment, more than 85% of the embryos survived an initial vitrification and warming and achieved comparable survival rates to those of their fresh counterparts. In contrast, those embryos subjected to a second vitrification and warming had clearly lower survival rates (60% and 64% for re vitrified embryos from the CCM and UBL groups, respectively) compared to the survival rates of the initial vitrification and fresh control groups (P < 0.01). Hatching rates were similar in re-vitrified blastocysts derived from vitrified CCMs and fresh control groups (50.8% and 55.3%, respectively). However, differences (P < 0.01) in hatching rates were recorded in re-vitrified blastocysts derived from vitrified UBLs and fresh control blastocysts (14.7% and 90.0%, respectively). In the second experiment, vitrified embryos were stored in a liquid nitrogen tank for one month. Then, the straws containing the embryos were transferred to a DS (DS group) or to another liquid nitrogen tank (control group) for an additional three days. Embryos from the DS and control groups had similar survival and hatching rates, regardless of the embryonic stage considered. The DS storage of CCMs and UBLs did not affect their development after culturing, including total cell numbers, compared to the control, although their apoptotic index was slightly higher (P < 0.05), regardless of the developmental stage. In conclusion, although re-vitrification negatively affects embryo survival, this study demonstrated that >60% of vitrified embryos could be successfully re-vitrified and re-warmed. The present study also showed the effectiveness of the DS for the storage of vitrified porcine CCMs and UBLs for at least three 3 days. PMID- 29567382 TI - Effect of short- and medium-term toxicity of doxorubicin on spermatogenesis in adult Wistar rats. AB - Doxorubicin (DXR) is a widely used chemotherapeutic anticancer agent that has potent activity against several solid and non-solid human malignant tumors, including childhood malignancies. However, DXR has serious toxic effects on tissues with rapid cell cycles, such as myeloid and lymphatic tissues, intestinal mucosa, testes and ovaries. In the present study, the short- and medium-term toxic effects of DXR on the reproductive system of male Wistar rats were evaluated using morphometric and stereological tools to quantify damage to the seminiferous epithelium. Adult male Wistar rats were treated with dose of 7.5 mg/kg of DXR and were sacrificed at seven, 14, 21 and 28 days after treatment. The testes were fixed in glutaraldehyde solution, routinely processed and embedded in plastic for evaluation under a light microscope. A significant reduction in testis weight was found as a result of massive germ cell apoptosis. Differences in comparison to the control group were found in the relative frequency of all stages of the seminiferous epithelium cycle, with significant differences for stages VIII-XI. Apoptosis significantly decreased the number of pachytene spermatocytes in the stages evaluated (I, II-III and VIII) at seven and 14 days. At 21 and 28 days after treatment, the testes exhibited the massive loss of germ cells that resulted in a missing cell layer. Moreover, reductions in the height of seminiferous tubules, tubular diameter and tubular compartment as well as an increase in the intertubular compartment were found in the period studied. PMID- 29567384 TI - Chlorin Nanoparticles for Tissue Diagnostics and Photodynamic Therapy. AB - BACKGROUND: Organic crystalline nanoparticles (NPs) are not fluorescent due to the crystalline structure of the flat molecules organized in layers. In earlier experiments with Aluminum Phthalocyanine (AlPc)-derived NPs, the preferential uptake and dissolution by macrophages was demonstrated [3]. Therefore, inflamed tissue or cancer tissue with accumulated macrophages may exhibit specific fluorescence in contrast to healthy tissue which does not fluoresce. The present study addresses the photobiological effects of NP generated from Temoporfin (mTHPC), a clinically utilized photosensitizer belonging to the chlorin family. METHODS: In-vitro investigations addressing uptake, dissolution and phototoxicity of mTHPC NP vs. the liposomal mTHPC formulation Foslip were performed using J774A.1 macrophages and L929 fibroblasts. For total NP uptake analysis, the cells were lysed, the nanoparticles dissolved and the fluorescence quantified. The intracellular molecular dissolution was measured by flow cytometry. Fluorescence microscopy served for controlling intracellular localization of the dissolved fluorescing molecules. Reaction mechanisms after PDT (mitochondrial activity, apoptosis) were analyzed using fluorescent markers in cell-based assays and flow cytometry. RESULTS: Organic crystalline NP of different size were produced from mTHPC raw material. NP were internalized more efficiently in J774A.1 macrophages when compared to L929 fibroblasts, whereas uptake and fluorescence of Foslip was similar between the cell lines. NP dissolution correlated with internalization levels for larger particles in the range of 200-500 nm. Smaller particles (45 nm in diameter) were taken up at high levels in macrophages, but were not dissolved efficiently, resulting in comparatively low intracellular fluorescence. Whereas Foslip was predominantly localized in membranes, NP-mediated fluorescence also co localized with acidic vesicles, suggesting endocytosis/phagocytosis as a major uptake mechanism. In macrophages, phototoxicity of NPs was stronger than in fibroblasts, even exceeding Foslip when administered in identical amounts. In both cell lines, phototoxicity correlated with mitochondrial depolarization and enhanced activation of caspase 3. CONCLUSIONS: Due to their preferential uptake/dissolution in macrophages, mTHPC NP may have potential for the diagnosis and photodynamic treatment of macrophage-associated disorders such as inflammation and cancer. PMID- 29567385 TI - [A structured case analysis from the Critical Incident Reporting System of the German Medical Association and the National Association of Statutory Health Insurance Physicians]. AB - BACKGROUND: Reporting systems for near misses are necessary to improve patient safety. In Germany, different systems are publicly available on both a national and regional level or as systems related to various medical domains. In contrast with the British Registry, our reporting systems still lack systematic evaluation. Using the Open-Task-Process Model (OPT model) one case of CIRSmedical (www.cirsmedical.de) was selected for a systematic analysis. METHOD: Case 148384 reports on a patient with a tentative diagnosis of pulmonary embolism with an oxygen saturation of 71 %. The attending physician was ordered to leave the patient to participate in the daily team meeting. After 40minutes, the nurses transferred the patient from the emergency department to the ICU. The OPT model systematically checks the properties of all tasks in a given process and matches them to requirements or solving capacities of the task. RESULTS: The analysis manifests some structural problems: Although the case was not very difficult (high priority, but a frequent problem), the solving capacities were not adequate in order to avoid errors. Since the physician left the patient, the loyalty toward medical standards and the team error correction activity were low. The team did not intervene to prevent the doctor from leaving his patient. CONCLUSION: The OPT model allows for the analysis of both single cases and complete data sets of CIR systems and is able to disclose structural problems of clinical management. PMID- 29567386 TI - The Grueneberg olfactory organ neuroepithelium recovers after injury. AB - The Grueneberg organ (also termed Grueneberg ganglion) is an olfactory subsystem at the rostral nasal septum of rodents, and has been suggested to exist also in humans. Grueneberg organ neurons respond to coldness and alarm pheromones, but the anatomical arrangement and regenerative capacity are not fully characterised. We examined the relationship between the glia and the neurons using crosses of two transgenic mouse lines, S100beta-DsRed and OMP-ZsGreen, to visualise olfactory ensheathing cells (OECs) and Grueneberg olfactory neurons, respectively. Within the epithelium, Grueneberg organ OECs were in direct contact with Grueneberg organ neuron cell bodies. Individual axons from the neurons initially grew over the surface of the OECs before forming larger fascicles consisting of numerous axons and OECs. Considering the location of the Grueneberg organ so close to the external environment, it may be that the Grueneberg neurons are likely to be subject to damage suggesting that as in other olfactory regions there is a capacity for recovery after injury. Here, we used a well characterised model of olfactory nervous system injury, unilateral bulbectomy, to determine whether Grueneberg organ neurons degenerate after injury. We found that Grueneberg organ neurons degenerated in response to the axotomy, yet by 11 days post injury neurons and/or axons were detected again within the epithelium. Our results demonstrate that while Grueneberg organ neurons and glia have a distinct relationship in the epithelium, they have largely similar characteristics to that of the main olfactory neurons and glia. PMID- 29567387 TI - The spatial molecular pattern of integrin recognition sites and their immobilization to colloidal nanobeads determine alpha2beta1 integrin-dependent platelet activation. AB - Collagen, a strong platelet activator, is recognized by integrin alpha2beta1 and GPVI. It induces aggregation, if added to suspended platelets, or platelet adhesion if immobilized to a surface. The recombinant non-prolylhydroxylated mini collagen FC3 triple helix containing one alpha2beta1 integrin binding site is a tool to specifically study how alpha2beta1 integrin activates platelet. Whereas soluble FC3 monomers antagonistically block collagen-induced platelet activation, immobilization of several FC3 molecules to an interface or to colloidal nanobeads determines the agonistic action of FC3. Nanopatterning of FC3 reveals that intermolecular distances below 64 nm between alpha2beta1 integrin binding sites trigger signaling through dot-like clusters of alpha2beta1 integrin, which are visible in high resolution microscopy with dSTORM. Upon signaling, these integrin clusters increase in numbers per platelet, but retain their individual size. Immobilization of several FC3 to 100 nm-sized nanobeads identifies alpha2beta1 integrin-triggered signaling in platelets to occur at a twentyfold slower rate than collagen, which activates platelet in a fast integrative signaling via different platelet receptors. As compared to collagen stimulation, FC3-nanobead triggered signaling cause a significant stronger activation of the protein kinase BTK, a weak and dispensable activation of PDK1, as well as a distinct phosphorylation pattern of PDB/Akt. PMID- 29567388 TI - Inducing hair follicle neogenesis with secreted proteins enriched in embryonic skin. AB - Organ development is a sophisticated process of self-organization. However, despite growing understanding of the developmental mechanisms, little is known about how to reactivate them postnatally for regeneration. We found that treatment of adult non-hair fibroblasts with cell-free extract from embryonic skin conferred upon them the competency to regenerate hair follicles. Proteomics analysis identified three secreted proteins enriched in the embryonic skin, apolipoprotein-A1, galectin-1 and lumican that together were essential and sufficient to induce new hair follicles. These 3 proteins show a stage-specific co-enrichment in the perifolliculogenetic embryonic dermis. Mechanistically, exposure to embryonic skin extract or to the combination of the 3 proteins altered the gene expression to an inductive hair follicle dermal papilla fibroblast-like profile and activated Igf and Wnt signaling, which are crucial for the regeneration process. Therefore, a cocktail of organ-specific extracellular proteins from the embryonic environment can render adult cells competent to re-engage in developmental interactions for organ neogenesis. Identification of factors that recreate the extracellular context of respective developing tissues can become an important strategy to promote regeneration in adult organs. PMID- 29567390 TI - Relationship between selenoprotein P and selenocysteine lyase: Insights into selenium metabolism. AB - Selenoprotein P (SelenoP) functions as a plasma transporter of selenium (Se) from liver to other tissues via incorporation into multiple selenocysteine (Sec) residues. Selenocysteine lyase (Scly) is an intracellular enzyme that decomposes Sec into selenide, providing Se for the synthesis of new selenoproteins. Both SelenoP and Scly are mostly produced by the liver. Previous studies demonstrated that male mice lacking SelenoP (SelenoP KO) or Scly (Scly KO) had increased or decreased total hepatic Se, respectively. While SelenoP regulation by Se is well studied, Scly regulation by Se has not been reported. We hypothesize that Scly is negatively regulated by Se levels, and that absence of SelenoP jeopardizes Scly dependent Se recycling. Using in vitro and in vivo models, we unveiled a tissue specific Se regulation of Scly gene expression. We also determined that SelenoP, a considered source of intracellular Se, affects Scly expression and activity in vitro but not in vivo, as in the absence of SelenoP, Scly levels and activity remain normal. We also showed that absence of SelenoP does not increase levels of transsulfuration pathway enzymes, which would result in available selenocompounds being decomposed by the actions of cystathionine gamma-lyase (CGL or CTH) and cystathionine beta-synthase (CBS). Instead, it affects levels of thioredoxin reductase 1 (Txnrd1), an enzyme that can reduce selenite to selenide to be used in selenoprotein production. This study evaluates a potential interplay between SelenoP and Scly, providing further insights into the regulation of selenium metabolism.

AB - Here we describe new fluorescent probes based on fluorescein and rhodamine that provide reversible, real-time insight into cellular redox status. The new probes incorporate bio-imaging relevant fluorophores derived from fluorescein and rhodamine linked with stable nitroxide radicals such that they cannot be cleaved, either spontaneously or enzymatically by cellular processes. Overall fluorescence emission is determined by reversible reduction and oxidation, hence the steady state emission intensity reflects the balance between redox potentials of critical redox couples within the cell. The permanent positive charge on the rhodamine-based probes leads to their rapid localisation within mitochondria in cells. Reduction and oxidation also leads to marked changes in the fluorophore lifetime, enabling monitoring by fluorescence lifetime imaging microscopy. Finally, we demonstrate that administration of a methyl ester version of the rhodamine-based probe can be used at concentrations as low as 5 nM to generate a readily detected response to redox stress within cells as analysed by flow cytometry. PMID- 29567389 TI - Polyphenol uses in biomaterials engineering. AB - Polyphenols are micronutrients obtained from diet that have been suggested to play an important role in health. The health benefits of polyphenols and their protective effects in food systems as antioxidant compounds are well known and have been extensively investigated. However, their functional roles as a "processing cofactor" in tissue engineering applications are less widely known. This review focuses on the functionality of polyphenols and their application in biomaterials. Polyphenols have been used to stabilize collagen and to improve its resistance to degradation in biological systems. Therefore, they have been proposed to improve the performance of biomedical devices used in cardiovascular systems by improving the mechanical properties of grafted heart valves, enhancing microcirculation through the relaxation of the arterial walls and improving the capillary blood flow and pressure resistance. Polyphenols have been found to stimulate bone formation, mineralization, as well as the proliferation, differentiation, and the survival of osteoblasts. These effects are brought about by the stimulatory effect of polyphenols on osteoblast cells and their protective effect against oxidative stress and inflammatory cytokines. In addition, polyphenols inhibit the differentiation of the osteoclast cells. Collectively, these actions lead to promote bone formation and to reduce bone resorption, respectively. Moreover, polyphenols can increase the cross-linking of dentine and hence its mechanical stability. Overall, polyphenols provide interesting properties that will stimulate further research in the bioengineering field. PMID- 29567394 TI - Consistent associations with beneficial bacteria in the seed endosphere of barley (Hordeum vulgare L.). AB - The importance of the plant microbiome for host fitness has led to the concept of the "plant holobiont". Seeds are reservoirs and vectors for beneficial microbes, which are very intimate partners of higher plants with the potential to connect plant generations. In this study, the endophytic seed microbiota of numerous barley samples, representing different cultivars, geographical sites and harvest years, was investigated. Cultivation-dependent and -independent analyses, microscopy, functional plate assays, greenhouse assays and functional prediction were used, with the aim of assessing the composition, stability and function of the barley seed endophytic bacterial microbiota. Associations were consistently detected in the seed endosphere with Paenibacillus, Pantoea and Pseudomonas spp., which were able to colonize the root with a notable rhizocompetence after seed germination. In greenhouse assays, enrichment with these bacteria promoted barley growth, improved mineral nutrition and induced resistance against the fungal pathogen Blumeria graminis. We demonstrated here that barley, an important crop plant, was consistently associated with beneficial bacteria inside the seeds. The results have relevant implications for plant microbiome ecology and for the holobiont concept, as well as opening up new possibilities for research and application of seed endophytes as bioinoculants in sustainable agriculture. PMID- 29567396 TI - Advances in microfluidics for lipid nanoparticles and extracellular vesicles and applications in drug delivery systems. AB - Lipid-based nanobiomaterials as liposomes and lipid nanoparticles (LNPs) are the most widely used nanocarriers for drug delivery systems (DDSs). Extracellular vesicles (EVs) and exosomes are also expected to be applied as DDS nanocarriers. The performance of nanomedicines relies on their components such as lipids, targeting ligands, encapsulated DNA, encapsulated RNA, and drugs. Recently, the importance of the nanocarrier sizes smaller than 100nm is attracting attention as a means to improve nanomedicine performance. Microfluidics and lab-on-a chip technologies make it possible to produce size-controlled LNPs by a simple continuous flow process and to separate EVs from blood samples by using a surface marker, ligand, or electric charge or by making a mass or particle size discrimination. Here, we overview recent advances in microfluidic devices and techniques for liposomes, LNPs, and EVs and their applications for DDSs. PMID- 29567392 TI - Small-molecule luminescent probes for the detection of cellular oxidizing and nitrating species. AB - Reactive oxygen species (ROS) have been implicated in both pathogenic cellular damage events and physiological cellular redox signaling and regulation. To unravel the biological role of ROS, it is very important to be able to detect and identify the species involved. In this review, we introduce the reader to the methods of detection of ROS using luminescent (fluorescent, chemiluminescent, and bioluminescent) probes and discuss typical limitations of those probes. We review the most widely used probes, state-of-the-art assays, and the new, promising approaches for rigorous detection and identification of superoxide radical anion, hydrogen peroxide, and peroxynitrite. The combination of real-time monitoring of the dynamics of ROS in cells and the identification of the specific products formed from the probes will reveal the role of specific types of ROS in cellular function and dysfunction. Understanding the molecular mechanisms involving ROS may help with the development of new therapeutics for several diseases involving dysregulated cellular redox status. PMID- 29567393 TI - Ascorbic acid metabolism and functions: A comparison of plants and mammals. AB - Ascorbic acid is synthesised by eukaryotes, the known exceptions being primates and some other animal groups which have lost functional gulonolactone oxidase. Prokaryotes do not synthesise ascorbate and do not need an ascorbate supply, so the functions that are essential for mammals and plants are not required or are substituted by other compounds. The ability of ascorbate to donate electrons enables it to act as a free radical scavenger and to reduce higher oxidation states of iron to Fe2+. These reactions are the basis of its biological activity along with the relative stability of the resulting resonance stabilised monodehydroascorbate radical. The importance of these properties is emphasised by the evolution of at least three biosynthetic pathways and production of an ascorbate analogue, erythroascorbate, by fungi. The iron reducing activity of ascorbate maintains the reactive centre Fe2+ of 2-oxoglutarate-dependent dioxygenases (2-ODDs) thus preventing inactivation. These enzymes have diverse functions and, recently, the possibility that ascorbate status in mammals could influence 2-ODDs involved in histone and DNA demethylation thereby influencing stem cell differentiation and cancer has been uncovered. Ascorbate is involved in iron uptake and transport in plants and animals. While the above biochemical functions are shared between mammals and plants, ascorbate peroxidase (APX) is an enzyme family limited to plants and photosynthetic protists. It provides these organisms with increased capacity to remove H2O2 produced by photosynthetic electron transport and photorespiration. The Fe reducing activity of ascorbate enables hydroxyl radical production (pro-oxidant effect) and the reactivity of dehydroascorbate (DHA) and reaction of its degradation products with proteins (dehydroascorbylation and glycation) is potentially damaging. Ascorbate status influences gene expression in plants and mammals but at present there is little evidence that it acts as a specific signalling molecule. It most likely acts indirectly by influencing the redox state of thiols and 2-ODD activity. However, the possibility that dehydroascorbylation is a regulatory post-translational protein modification could be explored. PMID- 29567397 TI - Nanopharmaceuticals for wound healing - Lost in translation? AB - Today, many of the newly developed pharmaceuticals and medical devices take advantage of nanotechnology and with a rising incidence of chronic diseases such as diabetes and cardiovascular disease, the number of patients afflicted globally with non-healing wounds is growing. This has created a requirement for improved therapies and wound care. However, converting the strategies applied in early research into new products is still challenging. Many of them fail to comply with the market requirements. This review discusses the legal and scientific challenges in the design of nanomedicines for wound healing. Are they lost in translation or is there a new generation of therapeutics in the pipeline? PMID- 29567398 TI - Delivery systems of current biologicals for the treatment of chronic cutaneous wounds and severe burns. AB - While wound therapy remains a clinical challenge in current medical practice, much effort has focused on developing biological therapeutic approaches. This paper presents a comprehensive review of delivery systems for current biologicals for the treatment of chronic wounds and severe burns. The biologicals discussed here include proteins such as growth factors and gene modifying molecules, which may be delivered to wounds free, encapsulated, or released from living systems (cells, skin grafts or skin equivalents) or biomaterials. Advances in biomaterial science and technologies have enabled the synthesis of delivery systems such as scaffolds, hydrogels and nanoparticles, designed to not only allow spatially and temporally controlled release of biologicals, but to also emulate the natural extracellular matrix microenvironment. These technologies represent an attractive field for regenerative wound therapy, by offering more personalised and effective treatments. PMID- 29567395 TI - In situ forming injectable hydrogels for drug delivery and wound repair. AB - Hydrogels have been utilized in regenerative applications for many decades because of their biocompatibility and similarity in structure to the native extracellular matrix. Initially, these materials were formed outside of the patient and implanted using invasive surgical techniques. However, advances in synthetic chemistry and materials science have now provided researchers with a library of techniques whereby hydrogel formation can occur in situ upon delivery through standard needles. This provides an avenue to minimally invasively deliver therapeutic payloads, fill complex tissue defects, and induce the regeneration of damaged portions of the body. In this review, we highlight these injectable therapeutic hydrogel biomaterials in the context of drug delivery and tissue regeneration for skin wound repair. PMID- 29567399 TI - The safety, tolerability and pharmacokinetics of BI 409306, a novel and potent PDE9 inhibitor: Overview of three Phase I randomised trials in healthy volunteers. AB - Safety, tolerability and pharmacokinetics of BI 409306, a potent and selective phosphodiesterase 9A inhibitor, were assessed in healthy subjects in three Phase I, within-dose group, double-blind trials. Trial 1 randomised young and elderly subjects to receive BI 409306 25, 50, 100 mg, placebo once daily (OD) or BI 409306 50 mg twice daily (young) for 14 days. Trial 2 randomised young poor metabolisers (PM) of cytochrome P450 isoform 2C19 (CYP2C19) and elderly subjects to receive BI 409306 25, 50 mg or placebo OD for 14 days. Trial 3 randomised Chinese and Japanese extensive metabolisers of CYP2C19 to receive single doses (SD) of BI 409306 25, 50, 100 mg or placebo and Chinese (PM) to SD of BI 409306 100 mg or placebo (Part 1). Japanese PM received SD of BI 409306 100 mg or placebo (Day 1) followed by BI 409306 100 mg or placebo OD for 7 days after a 48 hour washout period (Part 2). Reported adverse events (AE) were mild-to-moderate intensity and increased with BI 409306 dose. Eye disorders were most commonly reported (Trial 1: 40.0-41.7%, Trial 2: 29.2-37.5%, Trial 3: 18.2-66.7%) and increased with dose and systemic exposure. PM reported more AEs than other treatment groups, corresponding to higher systemic exposure to BI 409306. Systemic exposure to BI 409306 produced dose-dependent increases and was slightly greater in elderly versus young subgroups (Trial 1). Steady state was achieved by Day 2-3. Overall, BI 409306 demonstrated good safety, tolerability and minor accumulation after multiple dosing. PMID- 29567400 TI - Increased exploratory activity in rats with deficient sensorimotor gating: a study of schizophrenia-relevant symptoms with genetically heterogeneous NIH-HS and Roman rat strains. AB - Schizophrenia involves positive, negative and cognitive symptoms, as well as comorbidity with anxiety and obsessive-compulsive disorder. Prepulse inhibition (PPI) of the startle response is a measure of sensorimotor gating that is impaired in schizophrenia and animal models of the disease. Remarkably, impaired PPI has been related to other schizophrenia-like features in rodent models, such as cognitive deficits and hyperactivity. However, it remains to be investigated whether deficient PPI and increased exploratory activity are associated in genetically heterogeneous (outbred) naive animals. This study was undertaken to evaluate the relationships among PPI and other schizophrenia-related symptoms, such as augmented exploratory activity, anxiety and compulsivity in the genetically heterogeneous (outbred) NIH-HS rat stock (HS) and in the genetically selected inbred Roman High-Avoidance (RHA) and Low-avoidance (RLA) rats. Animals underwent the following tests: open-field (exploratory activity), elevated zero maze (anxiety-like behavior), marble burying (compulsive-like behavior), and PPI. Three groups of HS rats were formed according to their PPI scores, i.e. Low-PPI, Medium-PPI and High-PPI. The HS Low-PPI group displayed higher exploratory activity in the open-field than the HS Medium-PPI and HS High-PPI groups. Likewise, compared with their RLA counterparts, RHA rats exhibited lower PPI and more intense exploratory activity in the open-field test. Correlational and factorial analyses of the whole HS sample and the RHA/RLA data globally corroborated the results of the PPI-stratified HS subgroups. These data suggest that such a consistent association between impaired PPI and increased exploratory activity in outbred HS and inbred RHA/RLA rats is a relevant parameter that must be taken into account when modeling clusters of schizophrenia-relevant symptoms. PMID- 29567401 TI - A predator's response to a prey's deterrent signal changes with experience. AB - Prey signalling to predators is an attempt to divert or nullify an attack even before it occurs. If these signals are backed up by a potent defence, then the likelihood of the predators learning to avoid them is high. In species that use deceptive signalling, predators could learn to overcome such a display and diminish the efficacy of the display. We studied the effect of experience on the efficacy of tephritid fly displays against jumping spiders. We compared attacks on displaying flies, non-displaying flies, and two other prey species (a facile prey and a prey with a defence). Spiders were more likely to attack displaying flies over time. However, spiders that were familiar with the fly appearance but not display also increased their attack rates. We suggest that spiders attend to both components of the fly display, i.e. motion and appearance, but with motion cues taking priority. PMID- 29567402 TI - Suspiciousness in young minds: Convergent evidence from non-clinical, clinical and community twin samples. AB - BACKGROUND: We validated the Social Mistrust Scale (SMS) and utilized it to examine the structure, prevalence, and heritability of social mistrust in a large sample of Chinese children and adolescents. METHODS: In Study 1, a large sample of healthy twins (N=2094) aged 8 to 14years (M=10.27years, SD=2) completed the SMS. Structural equation modeling (SEM) was conducted to assess the structure of the SMS and to estimate the heritability of social mistrust in a sub-sample of twins (n=756 pairs). In Study 2, 32 adolescents with childhood-onset schizophrenia were compared with 34 healthy controls on levels of suspiciousness and clinical symptoms to examine the associations between the SMS and the Positive and Negative Syndrome Scale (PANSS). RESULTS: We found a three-factor structure for social mistrust (home, school, and general mistrust). Social mistrust was found to be moderately - heritable (19%-40%), with mistrust at home most strongly influenced by genetic factors. Compared with 11.76% of the healthy controls, 56.25% of the adolescents with early-onset schizophrenia exhibited very high levels of social mistrust on all three subscales of the SMS. The SMS exhibited good discriminant validity in distinguishing adolescents with childhood onset schizophrenia from healthy controls and showed associations with a broad range of symptoms assessed by the PANSS. CONCLUSIONS: Social mistrust assessed by the SMS may be heritable. The SMS demonstrates good discriminant validity with clinical diagnoses of schizophrenia. However, it seems to be correlated with multiple aspects of psychopathology in the schizophrenia group, rather than being specific to delusional ideation/paranoia. PMID- 29567404 TI - FIA-MS/MS determination of creatinine in urine samples undergoing butylation. AB - Flow injection analysis-tandem mass spectrometry has become widely used for analysis of many biomarkers in various biological matrices. To improve the sensitivity, the compounds are often determined as their butylesters. Since the concentration of urinary excreted compounds are generally reported after normalization to creatinine, the aim of this study was to investigate the possibility of creatinine determination in urine samples which underwent butylation. The impact of derivatization on urinary creatinine determination was investigated by measuring of underivatized and derivatized samples. The 10% creatine to creatinine conversion was observed during butylation, what above 700 MUmol creatine/mmol creatinine caused significant creatinine overestimation. In that case, correction for creatine conversion rate was done. QC samples at six concentration levels were examined and precision and accuracy values fulfill the European Medicine Agency validation requirements. The elaborated method was applied for determination of creatinine in 41 real human urine samples. Determined creatinine concentrations were in the range of 0.27-22.3 mmol/L, linearity was confirmed within the concentration range of 0.27-31.7 mmol/L. Obtained results highly correlated with routinely used enzymatic assay for all tested samples and proposed method provide reliable determination of creatinine in butylated urine in a single run with butylesters of other analytes of interest. PMID- 29567405 TI - Phylogenetic analysis of cnidarian peroxiredoxins and stress-responsive expression in the estuarine sea anemone Nematostella vectensis. AB - Peroxiredoxins (PRXs) are a family of antioxidant enzymes present in all domains of life. To date, the diversity and function of peroxiredoxins within animals have only been studied in a few model species. Thus, we sought to characterize peroxiredoxin diversity in cnidarians and to gain insight into their function in one cnidarian-the sea anemone Nematostella vectensis. Phylogenetic analysis using all six known PRX subfamilies (PRX1-4, PRX5, PRX6, PRXQ/AHPE1, TPX, BCP-PRXQ) revealed that like bilaterians, cnidarians contain representatives from three subfamilies (PRX1-4, PRX5, PRX6). Within the PRX1-4 subfamily, cnidarian sequences fall into two clades: PRX4, and a cnidarian-specific clade, which we term CNID-PRX. This phylogenetic analysis demonstrates that the three PRX subfamilies present in Bilateria were also present in the last common ancestor of the Cnidaria and Bilateria, and further that diversification of the PRX1-4 subfamily has occurred within the cnidarian lineage. We next examined the impact of decreased salinity, increased temperature, and peroxide exposure on the expression of four prx genes in N. vectensis (cnid-prx, prx4, prx5, and prx6). These genes exhibited unique expression patterns in response to these environmental stressors. Expression of prx4 decreased with initial exposure to elevated temperature, cnid-prx increased with exposure to elevated temperatures as well as with hydrogen peroxide exposure, and expression of all prxs transiently decreased with reduced salinity. Predicted subcellular localization patterns also varied among PRX proteins. Together these results provide evidence that peroxiredoxins in N. vectensis serve distinct physiological roles and lay a groundwork for understanding how peroxiredoxins mediate cnidarian developmental processes and environmental responses. PMID- 29567403 TI - Comparisons of schizotypal traits across 12 countries: Results from the International Consortium for Schizotypy Research. AB - BACKGROUND: Schizotypal traits are expressions of underlying vulnerability to psychotic disorders which have a potential impact on mental health status, neurocognition, quality of life, and daily functioning. To date, little research has examined epidemiologic landscape of schizotypal traits at the cross-national level. Our aim was to study the expression of schizotypal traits by sex, age, and country in a combined sample gathered from 12 countries. METHODS: A total of 27,001 participants completed the Schizotypal Personality Questionnaire (SPQ). The mean age of participants was 22.12 (SD=6.28); 37.5% (n=10,126) were males. RESULTS: Schizotypal traits varied according to sex, age, and country. Females scored higher than males in the positive dimension, whereas males scored higher in the disorganization dimension. By age, a significant decrease in the positive schizotypal traits was observed. Epidemiological expression of schizotypal traits varied by country. Moreover, several interactions by sex, age, and country were found. CONCLUSIONS: This pattern is similar to those found in patients with psychosis and psychotic-like experiences. These findings provide new insights and the opportunity to explore the phenotypic expression of schizotypal traits at cross-national level. PMID- 29567406 TI - Utilization of nano-cryptomelane for the removal of cobalt, cesium and lead ions from multicomponent system: Kinetic and equilibrium studies. AB - Nano-cryptomelane was prepared and characterized using SEM with mapping, HRTEM, FT-IR spectra, thermal analysis and surface area. The diameter distribution of nano-cryptomelane was found to be 4-6 nm. Sorption performance of the prepared material was studied for the removal of Co2+, Cs+ and Pb2+ from a multi-system solution of equal molar ratio, 1:1:1. The sorption capacity of nano-cryptomelane was found to be 179.6, 442.6 and 716.9 mg/g for Co2+, Cs+ and Pb2+, respectively. The kinetic studies revealed that the sorption process obeys non-linear pseudo second-order model and is controlled by an intra-particle diffusion mechanism. The equilibrium isotherm investigations outlined that the extended Langmuir isotherm model fits the data reasonably well and it is more applicable than Freundlich multicomponent sorption isotherm. The value of diffusion coefficient for the three metal ions is in the order 10-17 m2/s which indicates the chemisorption nature of the process. The desorption percentage attains the maximum value (98.13%, 97.29 and 97.04 for lead, cesium and cobalt ions, respectively) using 0.7 mol/L of HNO3. This revealed that nano-cryptomelane can be regenerated and reused for farther sorption of Pb2+, Cs+ and Co2+ from wastewater. PMID- 29567407 TI - Using machine learning and quantum chemistry descriptors to predict the toxicity of ionic liquids. AB - Large-scale application of ionic liquids (ILs) hinges on the advancement of designable and eco-friendly nature. Research of the potential toxicity of ILs towards different organisms and trophic levels is insufficient. Quantitative structure-activity relationships (QSAR) model is applied to evaluate the toxicity of ILs towards the leukemia rat cell line (ICP-81). The structures of 57 cations and 21 anions were optimized by quantum chemistry. The electrostatic potential surface area (SEP) and charge distribution area (Ssigma-profile) descriptors are calculated and used to predict the toxicity of ILs. The performance and predictive aptitude of extreme learning machine (ELM) model are analyzed and compared with those of multiple linear regression (MLR) and support vector machine (SVM) models. The highest R2 and the lowest AARD% and RMSE of the training set, test set and total set for the ELM are observed, which validates the superior performance of the ELM than that of obtained by the MLR and SVM. The applicability domain of the model is assessed by the Williams plot. PMID- 29567408 TI - Probabilistic risk assessment of exposure to fluoride in most consumed brands of tea in the Middle East. AB - The aim of this study was to evaluate the fluoride concentration in seven most consumed brands of tea in the Middle East which was imported to Iran through Zabol County. In the present study, the health risk of exposure to fluoride was estimated using a probabilistic approach. Monte Carlo simulation and sensitivity analysis were applied to quantify uncertainties in risk estimation. The highest mean and 95th percentile of chronic daily intake (CDI) was observed for children group. Iranian tea and Kenya tea had maximum CDI and target hazard quotient (THQ) values among studied brands of tea which followed by Green tea, Taksetare tea, Ceylan tea, Red tea, and White tea. These result indicated that there were significant risks of exposure to fluoride in most of studied brands of tea for children (THQ>1). Sensitivity analysis showed that fluoride concentration and daily intake were the most influential variables in three exposed populations. In conclusion, the fluoride concentration in some studied brands of tea is high and it put children at risk risks of exposure to fluoride. PMID- 29567409 TI - Portuguese preschool children: Benefit (EPA+DHA and Se) and risk (MeHg) assessment through the consumption of selected fish species. AB - This study aimed to assess the risk-benefit balance associated to fish consumption by Portuguese preschool children. For this purpose, databases (from IPMA and literature) were mined and mathematically processed by a model based on the Extreme Value Theory assuming consumption scenarios. Eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) and selenium (Se) and methylmercury (MeHg) were selected as critical components of fish, given their health impact and significant contents in some fish species. Assessment also took into account that Se may protect against MeHg toxicity. With exception of blue shark, Se Health Benefit Value (Se-HBV), was always positive (ranging between 3.3 and 14.9) and Se:MeHg ratio was always higher than one (3.8 to 32.3). It was also estimated that the deleterious effects of MeHg on children IQ were offset by the beneficial impact of EPA+DHA in fish except for grilled black scabbardfish consumed every day. Blue shark, regardless of the culinary treatment, yielded very high probabilities of exceeding MeHg TWI (higher than 84 % with a single weekly meal), thus raising serious concerns. EPA+DHA benefits were high in salmon regardless of culinary treatment (> 84 %). Fish consumption by children is advisable with exception of blue shark and boiled and grilled tuna. PMID- 29567410 TI - Person-centred care during prolonged weaning from mechanical ventilation, nurses' views: an interview study. AB - OBJECTIVE: To determine: 1) if the three elements of person-centred care (initiating, working and safeguarding the partnership) were present, and 2) to identify evidence of barriers to person-centred care during prolonged weaning from mechanical ventilation. RESEARCH METHODOLOGY: Secondary analysis of semi structured interviews with 19 critical care nurses using theoretical thematic analysis. SETTING: This study was conducted in three Swedish intensive care units, one in a regional hospital and two in a university hospital. FINDINGS: Three themes and nine subthemes related to person-centred care were identified. The three themes included: 1) 'finding a person behind the patient' related to the 'initiating the partnership' phase, 2) 'striving to restore patients sense of control' related to 'working the partnership' phase and 3) 'impact of patient involvement' related to 'safeguarding the partnership' phase of person-centred care'. Additionally a further theme 'barriers to person-centred care' was identified. CONCLUSION: We found evidence of all three person-centred care routines. Barriers to person-centred care comprised of lack team collaboration and resources. Facilitating patients to actively participate in decision-making during the weaning process may optimise weaning outcomes and warrants further research. PMID- 29567411 TI - Abnormal nuclear morphology is independent of longevity in a zmpste24-deficient fish model of Hutchinson-Gilford progeria syndrome (HGPS). AB - Lamin is an intermediate protein underlying the nuclear envelope and it plays a key role in maintaining the integrity of the nucleus. A defect in the processing of its precursor by a metalloprotease, ZMPSTE24, results in the accumulation of farnesylated prelamin in the nucleus and causes various diseases, including Hutchinson-Gilford progeria syndrome (HGPS). However, the role of lamin processing is unclear in fish species. Here, we generated zmpste24-deficient medaka and evaluated their phenotype. Unlike humans and mice, homozygous mutants did not show growth defects or lifespan shortening, despite lamin precursor accumulation. Gonadosomatic indices, blood glucose levels, and regenerative capacity of fins were similar in 1-year-old mutants and their wild-type (WT) siblings. Histological examination showed that the muscles, subcutaneous fat tissues, and gonads were normal in the mutants at the age of 1 year. However, the mutants showed hypersensitivity to X-ray irradiation, although p53target genes, p21 and mdm2, were induced 6 h after irradiation. Immunostaining of primary cultured cells from caudal fins and visualization of nuclei using H2B-GFP fusion proteins revealed an abnormal nuclear shape in the mutants both in vitro and in vivo. The telomere lengths were significantly shorter in the mutants compared to WT. Taken together, these results suggest that zmpste24-deficient medaka phenocopied HGPS only partially and that abnormal nuclear morphology and lifespan shortening are two independent events in vertebrates. PMID- 29567412 TI - Lipidome-wide disturbances of human placental JEG-3 cells by the presence of MEHP. AB - During pregnancy, exposure to environmental contaminants can lead to adverse effects on fetal growth and development, especially by targeting the placenta. Di(2-ethylhexyl)phthalate (DEHP), the most abundant chemical used in plastic materials, is known to induce toxicity on animals reproductive system and is suspected to give rise to similar effect in humans. Toxicity of DEHP is due to its main metabolite, MEHP, which is also known to disturb lipid synthesis in several organs. Moreover, mono-(2-ethylhexyl)phtalate (MEHP) is a high affinity ligand of the peroxisome proliferator-activated receptor PPARgamma which is essential for placental development and lipid metabolism. In order to investigate possible lipid disruptions induced by MEHP, in the JEG-3 human trophoblast cell line, a differential lipidomic analysis was carried out by UPLC-MS on both exposed and control cells. Our results showed that MEHP induced an important change of JEG-3 cells lipidome, especially in glycerolipids and glycerophospholipids, with a marked accumulation of triacylglycerols. For the first time, our results highlighted adverse effects of MEHP on human placental cells lipidome and thus, its potential effect on placental physiology. PMID- 29567413 TI - Hepatocellular carcinoma risk assessment by the measurement of liver stiffness variations in HCV cirrhotics treated with direct acting antivirals. AB - BACKGROUND: Direct-acting antivirals (DAA) are an effective treatment for hepatitis C virus infection. However, sustained virologic response (SVR) after DAA treatment does not seem to reduce the risk of hepatocellular carcinoma (HCC) development in these patients. Liver stiffness measurement (LSM) may predict the risk of developing HCC in liver cirrhosis patients. AIMS: The aim of our study was to evaluate the role of LSM variation as predictor of HCC development in patients treated with DAA. METHODS: In 139 HCV-related cirrhotic patients, LSM and laboratory tests were carried out at baseline (BL) and at the end of DAA treatment (EOT). Patients were followed for at least 6 months after the EOT. LSM reduction was expressed as Delta LS (?LS). Cox regression analysis was used to identify prognostic factors for HCC development after DAA. RESULTS: Median LSM values were significantly reduced from BL to EOT (from 18.6 to 13.8 kPa; p < 0.001). The median ?LS was -26.7% (IQR: -38.4% -13.6%). During a median follow-up of 15 months after DAA treatment, 20 (14.4%) patients developed HCC. Significant LSM reduction was observed both in patients who developed HCC and in those who did not, but this was significantly lower in the patients who developed HCC ( 18.0% vs -28.9% p = 0.005). At multivariate analysis, ?LS lower than -30%, Child Turcotte-Pugh-B and history of HCC were independently associated with HCC development. CONCLUSION: Our results indicate that ?LS is a useful non-invasive marker for predicting HCC development after DAA treatment. PMID- 29567414 TI - Actinobacteria: A relevant minority for the maintenance of gut homeostasis. AB - Actinobacteria are one the four major phyla of the gut microbiota and, although they represent only a small percentage, are pivotal in the maintenance of gut homeostasis. During the last decade many studies focused the attention on Actinobacteria, especially on their role both in gastrointestinal and systemic diseases and on their possible therapeutic use. In fact, classes of this phylum, especially Bifidobacteria, are widely used as probiotic demonstrating beneficial effects in many pathological conditions, even if larger in vivo studies are needed to confirm such encouraging results. This review aims to explore the current knowledge on their physiological functions and to speculate on their possible therapeutic role(s) in gastrointestinal and systemic diseases. PMID- 29567415 TI - Clinical and prognostic implications of acute onset of Autoimmune Hepatitis: An Italian multicentre study. AB - Autoimmune Hepatitis (AIH) can present under clinical profile as acute hepatitis of unexplained cause. We analyzed clinical, therapeutical and prognostic implications of AIH presenting as acute hepatitis in a cohort of patients admitted to 3 referral Centres in Italy. AIH onset was considered acute when transaminases were higher than 10 times the normal limit and/or bilirubin higher than 5 mg/ml (irrespectively from the histology, available only in 62% of cases). Among 479 patients diagnosed as AIH, 202 (43%) met the criteria of acute onset. This former group of patients on the basis of the histology has been subdivided in the "genuine" acute onset (83 pts) and acute "on chronic" onset (45 pts) At onset, clinical acute AIH showed significantly higher ALT, bilirubin and INR levels (p < 0.001 for all), lower albumin values (p = 0.001), similar IgG levels; Response to treatment was similar between the two groups. The progression to liver cirrhosis or its complications was significantly less frequent in acute onset AIH (13% vs. 22%, p = 0.02). The "genuine" acute patients showed a higher albumin serum levels (40 vs. 36, p = 0.001), lower INR levels (1.12 vs. 1.26, p = 0.002) and less tendency to the progression of liver disease (7% vs. 12%, p = NS) with respect to acute "on chronic" onset patients. Clinical acute hepatitis represents a common presentation of AIH, responds to standard immunosuppression regimen and would seem to be correlated with a better long-term prognosis.

PMID- 29567416 TI - Responses of seminal wheat seedling roots to soil water deficits. AB - The aims of this paper are to develop our understanding of the ways by which soil water deficits influence early wheat root growth responses, particularly how seminal roots respond to soil drying and the extent to which information on differences in soil water content are conveyed to the shoot and their impact on shoot behaviour. To achieve this, wheat seedlings have been grown, individually for around 25 days after germination in segmented soil columns within vertical plastic compartments. Roots were exposed to different soil volumetric moisture contents (SVMC) within the two compartments. Experiments where the soil in the lower compartment was allowed to dry to different extents, while the upper was maintained close to field capacity, showed that wheat seedlings allocated proportionally more root dry matter to the lower drier soil compartment. The total production of root, irrespective of the upper or lower SVMC, was similar and there were no detected effects on leaf growth rate or gas exchange. The response of seminal roots to proportionally increase their allocation of dry matter, to the drier soil was unexpected with such plasticity of roots system development traditionally linked to heterogeneous nutrient distribution than accessing soil water. In experiments where the upper soil compartment was allowed to dry, root growth slowed and leaf growth and gas exchange declined. Subsequent experiments used root growth rates to determine when seminal root tips first came into contact with drying soil, with the intentions of determining how the observed root growth rates were maintained as an explanation for the observed changes in root allocation. Measurements of seminal root ABA and ethylene from roots within the drying soil are interpreted with respect to what is known about the physiological control of root growth in drying soil.

AB - In recent decades, there has been a gradual increase in the prevalence of asthma. Various factors including environmental pollutants have contributed to this phenomenon. Plasticizer, di(2-ethylhexyl)phthalate (DEHP) is one of the commonest environmental pollutants due to its association with plastic products. DEHP gets released from plastic products easily leading to respiratory exposure in humans. As a consequence, DEHP is associated with allergic asthma in humans and animals. DEHP is reported to act as an adjuvant in ovalbumin-induced mouse models of asthma at high doses. However, these studies mostly looked into the role of DEHP on Th2 cytokines/eosinophilic inflammation without investigating the role of airway epithelial cells (AECs)/dendritic cells (DCs)/Th17 cells. Its adjuvant activity with natural allergens such as cockroach allergens at tolerable daily intake needs to be explored. Cockroach allergens and DEHP may be inhaled together due to their coexistence in work place as well as household environments. Therefore, effect of DEHP was assessed in cockroach allergens extract (CE) induced mouse model of asthma. Airway inflammation, histopathology, mucus secretion, and immune responses related to Th2/Th17/DCs and AECs were assessed in mice with DEHP exposure alone and in combination with CE. Our study shows that DEHP converts CE-induced eosinophilic inflammation into mixed granulocytic inflammation by promoting Th2 as well as Th17 immune responses. This was probably due to downregulation of E-cadherin in AECs, and enhancement of costimulatory molecules (MHCII/CD86/CD40)/pro-inflammatory cytokines (IL-6/MCP-1) in DCs by DEHP. This suggests that DEHP facilitates development of mixed granulocytic airway inflammation in the presence of a natural allergen. PMID- 29567419 TI - Validity of self-reported indicators to assess secondhand smoke exposure in the home. AB - INTRODUCTION: Questionnaires are widely used to assess secondhand smoke (SHS) exposure. However, the validity of self-reported SHS exposure indicators has been rarely assessed. We aimed to assess correlations, sensitivity, specificity, and predictive values between self-reported SHS exposure indicators and airborne nicotine concentrations. METHODS: We performed a cross-sectional study with a convenience sample of 175 homes in Barcelona and Santiago de Compostela, Spain. Airborne nicotine samples were collected from participants' homes and a self administered questionnaire was completed on SHS exposure in the home. Spearman correlations coefficients and sensitivity, specificity and predictive values were assessed between self-reported SHS exposure indicators and nicotine concentrations in the home. RESULTS: All self-reported SHS exposure indicators correlated moderately strongly with airborne nicotine concentrations (Spearman correlations coefficient ranging from 0.58 to 0.65). Moreover, sensitivities and negative predictive values between self-reported indicators and the presence of nicotine in the home were below 66.4% while specificities and positive predictive values were over 78.4%. The "number of people usually smoking in the home" showed the best results (rs = 0.65, p < 0.001; sensitivity = 50.4%, specificity = 95.2%, PPV = 95.0, NPV = 51.3). CONCLUSIONS: The self-reported SHS indicators assessed in this study showed moderate and strong correlations, low sensitivities, and high specificities. Among them, the best results were obtained with the "number of people usually smoking in the home". PMID- 29567420 TI - A study of telomere length, arsenic exposure, and arsenic toxicity in a Bangladeshi cohort. AB - BACKGROUND: Chronic arsenic exposure is associated with increased risk for arsenical skin lesions, cancer, and other adverse health outcomes. One potential mechanism of arsenic toxicity is telomere dysfunction. However, prior epidemiological studies of arsenic exposure, telomere length (TL), and skin lesion are small and cross-sectional. We investigated the associations between arsenic exposure and TL and between baseline TL and incident skin lesion risk among individuals participating in the Health Effects of Arsenic Longitudinal Study in Bangladesh (2000-2009). METHODS: Quantitative PCR was used to measure the average TL of peripheral blood DNA collected at baseline. The association between baseline arsenic exposure (well water and urine) and TL was estimated in a randomly-selected subcohort (n = 1469). A nested case-control study (466 cases and 464 age- and sex-matched controls) was used to estimate the association between baseline TL and incident skin lesion risk (diagnosed < 8 years after baseline). RESULTS: No association was observed between arsenic exposure (water or urine) and TL. Among incident skin lesion cases and matched controls, we observed higher skin lesion risk among individuals with shorter TL (Ptrend = 1.5 * 10-5) with odds ratios of 2.60, 1.59, and 1.10 for the first (shortest), second, and third TL quartiles compared to the fourth (longest). CONCLUSIONS: Arsenic exposure was not associated with TL among Bangladeshi adults, suggesting that leukocyte TL may not reflect a primary mode of action for arsenic's toxicity. However, short TL was associated with increased skin lesion risk, and may be a biomarker of arsenic susceptibility modifying arsenic's effect on skin lesion risk. PMID- 29567421 TI - Phytoremediation of sewage sludge contaminated by trace elements and organic compounds. AB - Phytoremediation is a green technique being increasingly used worldwide for various purposes including the treatment of municipal sewage sludge (MSS). Most plants proposed for this technique have high nutrient demands, and fertilization is often required to maintain soil fertility and nutrient balance while remediating the substrate. In this context, MSS could be a valuable source of nutrients (especially N and P) and water for plant growth. The aim of this study was to determine the capacity willow (Salix matsudana, cv Levante), poplar (Populus deltoides * Populus nigra, cv Orion), eucalyptus (Eucalyptus camaldulensis) and sunflower (Helianthus annuus) to clean MSS, which is slightly contaminated by trace elements (TEs) and organic pollutants, and to assess their physiological response to this medium. In particular, we aimed to evaluate the TE accumulation by different species as well as the decrease of TEs and organic pollutants in the sludge after one cropping cycle and the effect of MSS on plant growth and physiology. Since MSS did not show any detrimental effect on the biomass yield of any of the species tested, it was found to be a suitable growing medium for these species. TE phytoextraction rates depended on the species, with eucalyptus showing the highest accumulation for Cr, whereas sunflower exhibited the best performance for As, Cu and Zn. At the end of the trial, some TEs (i.e. Cr, Pb and Zn), n-alkanes and PCBs showed a significant concentration decrease in the sludge for all tested species. The highest Cr decrease was observed in pots with eucalyptus (57.4%) and sunflower (53.4%), whereas sunflower showed the highest Cu decrease (44.2%), followed by eucalyptus (41.2%), poplar (16.2%) and willow (14%). A significant decrease (41.1%) of Pb in the eucalyptus was observed. Zn showed a high decrease rate with sunflower (59.5%) and poplar (52%) and to a lesser degree with willow (35.3%) and eucalyptus (25.4%). The highest decrease in n-alkanes concentration in the sludge was found in willow (98.3%) and sunflower (97.3%), whereas eucalyptus has the lowest PCBs concentration (91.8%) in the sludge compared to the beginning of the trial. These results suggest new strategies (e.g. crop rotation and intercropping) to be adopted for a better management of this phytotechnology. PMID- 29567422 TI - Neuroprotective effect of IDPU (1-(7-imino-3-propyl-2,3-dihydrothiazolo [4,5 d]pyrimidin-6(7H)-yl)urea) in 6-OHDA induced rodent model of hemiparkinson's disease. AB - Parkinson's disease (PD) is a progressive neurodegenerative motor disorder characterized by the degeneration of dopaminergic nigrostriatal neurons. Levodopa (l-DOPA) is the most effective therapy for PD, however, PD progression continues with significant side effects in long term, thus necessitating the search for effective therapy that impedes PD progression. PD therapy through non dopaminergic pathways offers treatment without the risk of extrapyramidal effects. In this regard, earlier, we had reported, a novel compound IDPU with potential adenosine A2A receptor antagonist effect in haloperidol (chronic treatment) induced Parkinson model. In the present study, we extended our investigation towards i) evaluation of IDPU in well-established 6-OHDA induced Parkinson rat model to establish its role in the therapy of PD ii) its function in alleviating the neuronal loss. We carried the IDPU administration (i.p.) in rats for two weeks after establishing 6-OHDA induced unilateral lesions. The behavioral activity, neurochemical alteration, oxidative stress marker and tyrosine hydroxylase positive neurons in substantia nigra were analyzed. The results showed that IDPU significantly reduced motor and non-motor deficits induced by 6-OHDA in the behavioral tasks such as apomorphine, rota rod and force swim test. Furthermore, the results of oxidative stress biomarkers revealed that IDPU successfully modulated oxidative stress associated biomarkers such as MDA, catalase, superoxide dismutase, nitric oxide and reduced glutathione level. Additionally, IDPU significantly elevated intracellular dopamine, decreased glutamate and calcium levels in brain as compared to 6-OHDA alone treated animals which is evocative of its neuroprotective behavior. Thus, the investigations clearly validated IDPU as a potent anti-parkinsonian agent which showed immense capability to protect neurodegeneration. PMID- 29567423 TI - Alzheimer disease associated variants in SORL1 accelerate dementia development in Parkinson disease. AB - OBJECTIVE: Dementia in Parkinson disease (PD) is a common occurrence, and shows a marked overlap at a clinical and pathological level with Alzheimer's disease (AD), suggesting they share underlying disease mechanisms. Genetic variants in SORL1 have been identified in patients with AD, but a possible role in other dementias is unknown. The aim of this study was to investigate whether common polymorphisms in SORL1 affect the risk of developing dementia in a population based cohort of patients with incident PD. METHODS: One common, nonsynonymous SORL1 variant (rs2298813; A528T) was identified in whole exome sequencing data from 185 patients with PD from the Norwegian ParkWest study, who had been followed up to the 7-year visit after diagnosis. A528T was tested for association with PD risk, the development of dementia, and in a subset of patients (n = 103) for associations with established AD cerebrospinal fluid (CSF) biomarkers measured at the time of PD diagnosis. RESULTS: We found an association of A528T carrier status with increased risk of developing PD dementia (HR 2.31; 95% CI 1.09-4.90; p = 0.03) compared to non-carriers. Additionally, A528T carrier status was associated with a reduced ratio of CSF beta-amyloid 42 to p-Tau (p = 0.014) but no alterations in absolute AD marker levels (all p > 0.05) at the time of PD diagnosis. CONCLUSION: Our results show the first association of the AD risk factor SORL1 with incident dementia in PD, providing new evidence that AD related disease mechanisms may contribute to dementia in a subset of patients with PD. Finding support for a shared etiology for AD and PD dementia provides new directions for research into treatments for these diseases. PMID- 29567424 TI - Altered intrinsic brain functional connectivity in drug-naive Parkinson's disease patients with LRRK2 mutations. AB - BACKGROUND: Leucine-rich repeat kinase 2 (LRRK2) has been recently identified as a causative gene of Parkinson's disease (PD), and the LRRK2 R1628P and G2385R mutations are common in ethnic Han-Chinese PD patients. However, the pathogenic mechanism of LRRK2 mutations in PD remains largely unknown. METHODS: Resting state functional MRI (fMRI) was used to assess the functional connectivity (FC) of the striatal subregions of 11 ethnic Han-Chinese drug-naive PD patients with the LRRK2 R1628P or G2385R mutations, 11 ethnic Han-Chinese drug-naive PD patients without such mutations, and 22 healthy control (HC) subjects. RESULTS: Compared with the HC subjects, both subgroups of the PD patients showed alterations in the FC within the sensorimotor-striatal and posterior putamen striatal circuits. In addition, relative to the subgroup of PD patients without the LRRK2 mutations, the subgroup of PD patients with the LRRK2 mutation exhibited decreased FC between the putamen and the bilateral superior frontal gyri, precuneus and calcarine gyri. The FC between the putamen and the bilateral superior frontal gyri decreased with age in the LRRK2 mutation carriers but not in the non-carriers. CONCLUSION: Differences in the FC between ethnic Han-Chinese drug-naive PD patients with and without the LRRK2 mutation may provide new insights into the understanding of the neural functional changes in ethnic Han Chinese PD patients with LRRK2 mutations. However, our results are preliminary, and further investigations are needed. PMID- 29567425 TI - Association between self-reported impulsiveness and gray matter volume in healthy adults. An exploratory MRI study. AB - This exploratory study investigated the association between self-reported impulsiveness and cortical gray matter volume (GMV) of the entire cortex in healthy adults. As a secondary objective and based on preliminary findings concerning the positive association between self-reported impulsiveness and the slant of the forehead degrees (SFD), we analyzed associations between SFD, GMV and impulsiveness. We obtained 48 structural magnetic resonances. The participants also completed BIS 11 and profile pictures were obtained. SFD was measured by a photographic support and a protractor. The GMV of the whole cortex was obtained for each participant through Freesurfer. Firstly, we found negative and positive correlations between fronto-temporal and occipital areas respectively and BIS. Second, we found negative correlations between SFD and GMV in right postcentral gyrus, right caudal middle frontal gyrus, right transverse temporal cortex and positive correlation in left entorhinal cortex. Third, we observed a positive correlation between SFD and BIS in all impulsiveness scores. In conclusion, variations in fronto-temporal and posterior cerebral areas are crucial for BIS in healthy adults. Furthermore, SFD was associated with BIS and correlated with GMV areas involved in self-reported impulsiveness. PMID- 29567426 TI - miR-494-3p modulates the progression of in vitro and in vivo Parkinson's disease models by targeting SIRT3. AB - Parkinson's disease (PD) is the second most prevalent chronic and progressive neurodegenerative disease. Plenty of miRNAs have been demonstrated to participate in the pathogenesis of PD. However, the detailed roles of miR-494-3p and underlying mechanisms involved in PD progression remain to be explored. In the present study, we found that miR-494-3p expression was increased and sirtuin 3 (SIRT3) expression was decreased in SH-SY5Y cells following 1-Methyl-4 phenylpyridinium (MPP+) treatment. Loss-of-function showed that miR-494-3p inhibition promoted cell viability and superoxide dismutase (SOD) activity, and suppressed apoptotic rate, caspase-3 activity, lactate dehydrogenase (LDH) activity, tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL 1beta) expressions, and reactive oxygen species (ROS) generation in MPP+-induced SH-SY5Y cells. Moreover, SIRT3 was identified as a target of miR-494-3p and miR 494-3p negatively regulated SIRT3 expression in SH-SY5Y cells. Additionally, up regulation of miR-494-3p suppressed SIRT3 expression and exacerbated motor impairment in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model. In conclusion, miR-494-3p inhibition exerted a neuroprotective role in MPP+-induced PD by targeting SIRT3, providing a possible therapeutic strategy for PD patients. PMID- 29567427 TI - N-acylethanolamine hydrolyzing acid amidase inhibition: tools and potential therapeutic opportunities. AB - N-acylethanolamines (NAEs) (e.g., N-palmitoylethanolamine, N arachidonoylethanolamine, N-oleoylethanolamine) are bioactive lipids involved in many physiological processes including pain, inflammation, anxiety, cognition and food intake. Two enzymes are responsible for the hydrolysis of NAEs and therefore regulate their endogenous levels and effects: fatty acid amide hydrolase (FAAH) and N-acylethanolamine-hydrolyzing acid amidase (NAAA). As discussed here, extensive biochemical characterization of NAAA was carried out over the years that contributed to a better understanding of NAAA enzymology. An increasing number of studies describe the synthesis and pharmacological characterization of NAAA inhibitors. Recent medicinal chemistry efforts have led to the development of potent and stable inhibitors that enable studying the effects of NAAA inhibition in preclinical disease models, notably in the context of pain and inflammation. PMID- 29567428 TI - Synthesis, molecular modelling and biological evaluation of tetrasubstituted thiazoles towards cholinesterase enzymes and cytotoxicity studies. AB - Alzheimer is a neurodegenerative disease and requires the development of new scaffold to treat it. In this regard, thiazoles derivative are playing their significant role. In the current research paper we have focused our attention for the development of tetrasubstituted thiazole (3a-h) derivatives using domino synthesis by mixing the thiourea as a precursor, with acetophenone in the presence of iodine and tosic acid in DMSO and refluxed for 12-22 h. The structures of the newly synthesized compounds were confirmed by FTIR, 1H NMR, 13C NMR and EIMS analysis. Thiazole derivatives were analyzed for their biological significances against acetyl and butylcholinesterase enzymes and compound 3b and 3d were found more active against these enzyme, respectively. The mode of inhibition was determined for the potent compounds against both the enzymes. Moreover, the molecular docking studies were carried out to explore the interactive behavior of the compounds within the active pocket of enzymes. Furthermore, the derivatives (3a-h) were evaluated for their anticancer potential against HeLa cancer cell lines. Most potent inhibition was observed by compound 3b. PMID- 29567429 TI - Design, synthesis and biological evaluation of novel 1,3,4-trisubstituted pyrazole derivatives as potential chemotherapeutic agents for hepatocellular carcinoma. AB - A series of novel 1,3,4-trisubstituted pyrazole derivatives were synthesized and evaluated for their cytotoxic activity against three different cancer cell lines namely HCT116, UO-31 and HepG2. Compounds 3b, 3d, 7b and 9 showed excellent anticancer activity against all the tested cancer cell lines and had better cytotoxic activities than the reference drug, Sorafenib. Therefore, these compounds were chosen to be further evaluated in a panel of HCC cell lines. Among them, 3b and 7b were the most active compounds against HCC cells used here. Further studies on the mechanism demonstrated that 3b and 7b induced apoptosis in addition to induction of cell cycle arrest at G2/M phase in HepG2 and Huh7 cells. Consistent with these results, caspase-3 assay was done and the results revealed that the pro-apoptotic activity of the target compounds could be due to the stimulation of caspases-3. In addition, CDK1 inhibition assay was done and it was found that compounds 3b and 7b inhibited CDK1 activities with IC50 values of 2.38 and 1.52 uM, respectively. Finally, pyrazole derivatives 3b and 7b showed potent bioactivities, indicating that these compounds could be potent anticancer drugs in the future. PMID- 29567430 TI - IPEX due to an exon 7 skipping FOXP3 mutation with autoimmune diabetes mellitus cured by selective TReg cell engraftment. AB - Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare inherited disorder leading to severe organ-specific autoimmunity. IPEX is caused by hemizygous mutations in FOXP3, which codes for a master transcription factor of regulatory T (TReg) cell development and function. We describe a four-year-old boy with typical but slightly delayed-onset of IPEX with autoimmune diabetes mellitus, enteropathy, hepatitis and skin disease. We found the unreported FOXP3 splice site mutation c.816+2T>A that leads to the loss of leucine-zipper coding exon 7. RNA-Seq revealed that FOXP3Delta7 leads to differential expression of FOXP3 regulated genes. After myeloablative conditioning the patient underwent allogeneic HSCT from a matched unrelated donor. HSCT led to the resolution of all IPEX symptoms including insulin requirement despite persisting autoantibody levels. After initial full donor engraftment nearly complete autologous reconstitution was documented, but donor derived TReg cells persisted with a lineage-specific chimerism of >70% and the patient remained in clinical remission. PMID- 29567431 TI - Immunomodulating peptides derived from different human endogenous retroviruses (HERVs) show dissimilar impact on pathogenesis of a multiple sclerosis animal disease model. AB - Retroviruses including Human Endogenous Retroviruses (HERVs), contain a conserved region with highly immunomodulatory functions in the transmembrane proteins in envelope gene (env) named immunosuppressive domain (ISU). In this report, we demonstrate that Env59-GP3 peptide holds therapeutic potential in a mouse model of myelin oligodendrocyte glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE). The results show that this specific HERV-H derived ISU peptide, but not peptide derived from another env gene HERV-K, decreased the development of EAE in C57BL/6 mice, accompanied by reduced demyelination and inhibition of inflammatory cells. Moreover, here we tested the effect of peptides on macrophages differentiation. The treatment with Env59-GPS peptide modulate the pro-inflammatory M1 profile and anti-inflammatory M2 macrophages, being shown by inhibiting inflammatory M1 hallmark genes/cytokines expression and enhancing expression of M2 associated markers. These results demonstrate that Env59-GP3 ISU peptide has therapeutic potential in EAE possibly through inducing the polarization of M2 macrophages and inhibiting inflammatory responses. PMID- 29567432 TI - Exploiting risk-reward structures in decision making under uncertainty. AB - People often have to make decisions under uncertainty-that is, in situations where the probabilities of obtaining a payoff are unknown or at least difficult to ascertain. One solution to this problem is to infer the probability from the magnitude of the potential payoff and thus exploit the inverse relationship between payoffs and probabilities that occurs in many domains in the environment. Here, we investigated how the mind may implement such a solution: (1) Do people learn about risk-reward relationships from the environment-and if so, how? (2) How do learned risk-reward relationships impact preferences in decision-making under uncertainty? Across three experiments (N = 352), we found that participants can learn risk-reward relationships from being exposed to choice environments with a negative, positive, or uncorrelated risk-reward relationship. They were able to learn the associations both from gambles with explicitly stated payoffs and probabilities (Experiments 1 & 2) and from gambles about epistemic events (Experiment 3). In subsequent decisions under uncertainty, participants often exploited the learned association by inferring probabilities from the magnitudes of the payoffs. This inference systematically influenced their preferences under uncertainty: Participants who had been exposed to a negative risk-reward relationship tended to prefer the uncertain option over a smaller sure option for low payoffs, but not for high payoffs. This pattern reversed in the positive condition and disappeared in the uncorrelated condition. This adaptive change in preferences is consistent with the use of the risk-reward heuristic. PMID- 29567433 TI - Phage particles harboring antibiotic resistance genes in fresh-cut vegetables and agricultural soil. AB - Bacteriophages are ubiquitously distributed prokaryotic viruses that are more abundant than bacteria. As a consequence of their life cycle, phages can kidnap part of their host's genetic material, including antibiotic resistance genes (ARGs), which released phage particles transfer in a process called transduction. The spread of ARGs among pathogenic bacteria currently constitutes a serious global health problem. In this study, fresh vegetables (lettuce, spinach and cucumber), and cropland soil were screened by qPCR for ten ARGs (blaTEM, blaCTX-M 1 group, blaCTX-M-9 group, blaOXA-48, blaVIM, mecA, sul1, qnrA, qnrS and armA) in their viral DNA fraction. The presence of ARGs in the phage DNA was analyzed before and after propagation experiments in an Escherichia coli host strain to evaluate the ability of the phage particles to infect a host. ARGs were found in the phage DNA fraction of all matrices, although with heterogeneous values. ARG prevalence was significantly higher in lettuce and soil, and the most common overall were beta-lactamases. After propagation experiments, an increase in ARG densities in phage particles was observed in samples of all four matrices, confirming that part of the isolated phage particles were infectious. This study reveals the abundance of free, replicative ARG-containing phage particles in vegetable matrices and cropland soil. The particles are proposed as vehicles for resistance transfer in these environments, where they can persist for a long time, with the possibility of generating new resistant bacterial strains. Ingestion of these mobile genetic elements may also favor the emergence of new resistances, a risk not previously considered. PMID- 29567435 TI - Piezotome Genioplasty Reduces Postsurgical Morbidity and Enhances Patient Satisfaction: A Randomized Clinical Trial. AB - PURPOSE: Recent clinical studies have shown piezotomes might establish the new "state of the art" for osteotomies in maxillofacial surgery. The author hypothesized genioplasty surgery with piezotomes might decrease postsurgical morbidity and increase overall patient satisfaction compared with genioplasty with traditional instruments. MATERIALS AND METHODS: The author implemented a randomized clinical trial. The sample was composed of patients undergoing reductive genioplasty. The predictor variable was genioplasty performed with traditional instruments and a traditional sliding genioplasty protocol (control group) or ultrasonic surgical devices (Piezotome II and Piezotome SOLO M+) with a piezotome-adapted 3-dimensional curved osteotomy surgical protocol (test group). The primary outcome variable was overall long-term patient satisfaction determined by the Genioplasty Outcome Evaluation. Other study variables were postsurgical morbidity assessed by the Universal Pain Assessment Scale, analgesic intake, neurosensory 2-point discrimination test of the lip and chin, and surgery duration. Descriptive and bivariate statistics were computed by SPSS 22.0 and the P value was set at .05. RESULTS: The sample was composed of 48 patients undergoing reductive genioplasty with a piezotome (10 men and 13 women; age, 24 to 56 yr) or traditional sliding genioplasty (11 men and 14 women; age, 26 to 54 yr). No statistically relevant difference was found for surgery duration between the test and control groups. There was a statistically significant association between decreased postsurgical morbidity (P < .05) and higher overall long-term patient satisfaction with genioplasty outcome (P < .05) when piezotomes were used for performing the genioplasty. CONCLUSION: The results of this study suggest the use of piezotomes and piezotome-adapted surgical protocols is advantageous in genioplasty surgery compared with traditional surgical instruments and traditional surgical protocols. PMID- 29567434 TI - Using a local low rank plus sparse reconstruction to accelerate dynamic hyperpolarized 13C imaging using the bSSFP sequence. AB - Acceleration of dynamic 2D (T2 Mapping) and 3D hyperpolarized 13C MRI acquisitions using the balanced steady-state free precession sequence was achieved with a specialized reconstruction method, based on the combination of low rank plus sparse and local low rank reconstructions. Methods were validated using both retrospectively and prospectively undersampled in vivo data from normal rats and tumor-bearing mice. Four-fold acceleration of 1-2 mm isotropic 3D dynamic acquisitions with 2-5 s temporal resolution and two-fold acceleration of 0.25-1 mm2 2D dynamic acquisitions was achieved. This enabled visualization of the biodistribution of [2-13C]pyruvate, [1-13C]lactate, [13C, 15N2]urea, and HP001 within heart, kidneys, vasculature, and tumor, as well as calculation of high resolution T2 maps. PMID- 29567436 TI - The Effects of Noncontinuous Positive Airway Pressure Therapies on the Aerodynamic Characteristics of the Upper Airway of Obstructive Sleep Apnea Patients: A Systematic Review. AB - PURPOSE: The effects of noncontinuous positive airway pressure (non-CPAP) therapies on the airflow in the upper airway in obstructive sleep apnea (OSA) patients are not completely clear yet. Therefore, the primary aim of this systematic review was to determine the effects of various non-CPAP therapies on the aerodynamic characteristics of the upper airway in OSA patients. MATERIALS AND METHODS: A PICO (population or patient, intervention, comparison, outcome) search strategy, focusing on the effects of various non-CPAP therapies on the aerodynamic characteristics of the upper airway (ie, velocity, wall shear stress, wall static pressure, airway resistance, pressure drop, and pressure effort) of OSA patients, was conducted in the following databases: MEDLINE (PubMed), Embase (Excerpta Medica), and Web of Science. In this systematic review, the inclusion criteria were 1) adults diagnosed with OSA by polysomnography, 2) treatment outcome assessed by a second polysomnography, and 3) computational fluid dynamics (CFD) applied. RESULTS: Of 51 unique studies retrieved, 9 fulfilled the criteria for this systematic review. Seven studies were on maxillomandibular advancement (MMA) surgery, and 2 were on mandibular advancement device (MAD) therapy. The aerodynamic characteristics of the upper airway improved in OSA patients who underwent MMA surgery. However, the studies on MMA surgery included only responders to MMA surgery. In the responders to MAD therapy, the velocity, wall static pressure, and airway resistance of the upper airway decreased. In nonresponders to MAD therapy, the wall static pressure and airway resistance of the upper airway increased. CONCLUSIONS: This systematic review suggests that MMA surgery and MAD therapy may improve several aerodynamic characteristics of the upper airway in OSA patients by CFD analysis. However, because of limitations of the selected studies, there is not enough evidence yet to support CFD analysis as a routine tool to predict the treatment outcome in OSA patients.

AB - The temporomandibular joints are often affected by juvenile idiopathic arthritis, but few evidence-based management strategies exist. Intra-articular steroid injection (IASI) is a common intervention and is associated with pain reduction and improved mandibular function. Emerging evidence, however, suggests that IASI may actually impair rather than improve mandibular growth. It is therefore time to reconsider this practice.

Relevant variables were: tanning methods ever used, demographics, and location and refusal of UV tanning device (beds, lamps) use in the past 12 months. Data were weighted so total survey weights by male/female, grade and province equal actual enrolments in these groups. Analyses were conducted in SAS, mostly for grades 10 and 11. Rao-Scott chi squared tests and p-values were calculated. Among 6803 grade 10 and 11 participants, 82% tanned intentionally, mostly by being/playing outside, or laying in the sun. Spray/self-tanners were used by 15% of participants. UV tanning device use was uncommon (4.4%), lowest in Ontario (2.7%) and British Columbia (3.8%), which have legislation against use among youth. Of 202 who used UV tanning devices in the past 12 months, most did at salons/studios (85%), 35% at home and 30% at a gym. Two hundred and forty-nine participants (3.4%) were refused use of UV tanning devices in the past 12 months. While legislation appears to deter UV tanning device use, it appears to have no impact on UV exposure among high school students overall. Greater prevention efforts are required to deter intentional tanning among high school students.

AB - Preventive medical care may reduce downstream medical costs and reduce population burden of disease. However, although social, demographic, and geographic determinants of preventive care have been studied, there is little information about how the workplace affects preventive care utilization. This study examines how four types of organizational policies and practices (OPPs) are associated with individual workers' preventive care utilization. We used data collected in 2012 from 838 hospital patient care workers, grouped in 84 patient care units at two hospitals in Boston. Via survey, we assessed individuals' perceptions of four types of OPPs on their work units. We linked the survey data to a database containing detailed information on medical expenditures. Using multilevel models, we tested whether individual-level perceptions, workgroup-average perceptions, and their combination were associated with individual workers' preventive care utilization (measured by number of preventive care encounters over a two-year period). Adjusting for worker characteristics, higher individual-level perceptions of workplace flexibility were associated with greater preventive care utilization. Higher average unit-level perceptions of people-oriented culture, ergonomic practices, and flexibility were associated with greater preventive care utilization. Overall, we find that workplace policies and practices supporting flexibility, ergonomics, and people-oriented culture are associated with positive preventive care-seeking behavior among workers, with some policies and practices operating at the individual level and some at the group level. Improving the work environment could impact employers' health-related expenditures and improve workers' health-related quality of life. PMID- 29567440 TI - A Modified Atrial Volume Reduction Technique for a Giant Left Atrium. AB - We describe a modified volume reduction technique for a giant left atrium that consists of circumferential resection of a strip of left atrial wall with the appendage, plicated pericardium replacing the posterior atrial wall, and anastomoses of the remaining right side free wall to the interatrial septum instead of the interatrial groove. Our initial application showed that this technique can safely reduce a giant left atrium to the desired volume and obtain a high rate of sinus rhythm restoration after a maze operation.

PMID- 29567442 TI - Spontaneous Right Atrial Dissection and Congenital Right Atrial Aneurysm. AB - Right atrial (RA) wall dissection and congenital RA aneurysm is a very rare abnormality. This is may be the first reported case of a spontaneous dissection of the RA wall without rupture, in addition to the presence of a congenital RA aneurysm. The patient, a 4-year-old boy, was successfully treated with RA aneurysm resection under cardiopulmonary bypass. Although the diagnosis of RA dissection poses a challenge even when the advanced multimodality imaging approaches are applied, transthoracic and contrast echocardiography are most valuable tools for making accurate diagnosis. PMID- 29567443 TI - Simultaneous determination of 21 trace perfluoroalkyl substances in fish by isotope dilution ultrahigh performance liquid chromatography tandem mass spectrometry. AB - Perfluoroalkyl substances (PFASs) have been identified as emerging environmental contaminants. In this study, an efficient and accurate ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was developed for simultaneous determination of 21 PFASs in fish. Acetonitrile was used for sample extraction. Solid phase extraction (SPE) by WAX cartridges and then freezing at -30 degrees C were adopted as cleanup strategies. Strict measurements were performed to control background contamination during the whole procedure. Matrix effects were evaluated by external standard and isotope dilution mass spectrometry (IDMS) methods. IDMS can compensate the matrix effects to a large extent. The method detection limits (MDLs) ranged from 2 pg/g to 10 pg/g except for PFBA (120 pg/g). The method quantitation limits (MQLs) ranged from 5 pg/g to 30 pg/g except for PFBA (300 pg/g). The matrix spiked recoveries of three spiked levels were in the range of 79.6%-109%. The intra-day relative standard deviation (RSD) and inter-day RSD were from 0.94% to 13.9% and 0.36% to 11.2% respectively. Two fish tissue reference materials were analyzed by the developed method. The results of reference materials were within the uncertainty of the given value. The quantitative results of IDMS and standard addition (SA) - IDMS were comparable. The developed UHPLC-MS/MS method was applied for PFASs detection in 20 marine fish samples. 9 PFASs were detected in the samples with the ?9PFASs concentration range of 0.04 to 2.14 ng/g wet weight (ww).

AB - Accurate estimation of pollutant emissions from household solid fuel combustion has been a challenging issue in developing regions, especially in the heavily polluted northern China region. Basing on a survey of residential household energy use in all villages in Beijing, this study developed a village-based emission inventory of PM2.5, SO2, NOx, and NMVOCs emitted from household combustion in Beijing, as well as three emission control scenarios. Notably, 3805 kt and 556 kt of coal were used for household heating and cooking in 2015, respectively. The emissions of NOX, NMVOCs, SO2, and PM2.5forhousehold heating totaled11.5 kt, 29.3 kt, 43.1 kt, and 34.7 kt in 2015, respectively, while those for household cooking totaled 1.55 kt, 4.02 kt, 6.55 kt, and 3.99 kt. Emissions from household heating contributed to~70% of PM2.5 and ~60% of SO2 emissions in winter. Additionally, downtown Beijing is surrounded by polluted suburbs. A coal forbiddance policy (e.g. "coal to gas") could gradually improve the air quality in urban Beijing. PMID- 29567445 TI - The antidepressant fluoxetine alters mechanisms of pre- and post-copulatory sexual selection in the eastern mosquitofish (Gambusia holbrooki). AB - Contamination of aquatic habitats with pharmaceuticals is a major environmental concern. Recent studies have detected pharmaceutical pollutants in a wide array of ecosystems and organisms, with many of these contaminants being highly resistant to biodegradation and capable of eliciting sub-lethal effects in non target species. One such pollutant is fluoxetine, a widely prescribed antidepressant, which is frequently detected in surface waters globally and can alter physiology and behaviour in aquatic organisms. Despite this, relatively little is known about the potential for fluoxetine to disrupt mechanisms of sexual selection. Here, we investigate the impacts of 30-day exposure to two environmentally realistic levels of fluoxetine (low and high) on mechanisms of pre- and post-copulatory sexual selection in the eastern mosquitofish (Gambusia holbrooki). We tested 1) male mating behaviour in the absence or presence of a competitor male, and 2) sperm quality and quantity. We found that high-fluoxetine exposure increased male copulatory behaviour in the absence of a competitor, while no effect was detected under male-male competition. Further, fluoxetine exposure at both concentrations increased total sperm count relative to males from the control group, while no significant change in sperm quality was observed. Lastly, low-fluoxetine males showed a significant reduction in condition index (mass relative to length). Our study is the first to show altered mechanisms of both pre- and post-copulatory sexual selection in an aquatic species resulting from environmentally realistic fluoxetine exposure, highlighting the capacity of pharmaceutical pollution to interfere with sensitive reproductive processes in wildlife. PMID- 29567446 TI - Melamine and its derivatives in dog and cat urine: An exposure assessment study. AB - Melamine is a nitrogen-containing organic compound that is used in a wide range of products, including paints, plastics, and paper, as a flame retardant. A few studies have reported the occurrence of melamine and its derivatives in pet food, following a number of deaths of cats and dogs from kidney failure in 2007, which was attributed to melamine contamination in ingredients used in pet food. Nevertheless, studies that report the occurrence of melamine and its derivatives in pet urine are scarce. In this study, we measured melamine and its derivatives (i.e., ammeline, ammelide, and cyanuric acid) in dog (n = 30) and cat (n = 30) urine collected from Albany, New York, USA, during March through July 2017. The mean (+/-SD) concentrations of melamine, ammeline, ammelide, and cyanuric acid in dog urine were 21.1 +/- 51.2, 2.3 +/- 3.8, 9.9 +/- 1 0.4, and 79.0 +/- 105 ng/mL, respectively; the corresponding concentrations in cats were 21.4 +/- 26.1, 1.2 +/ 2.5, 6.1 +/- 3.9, and 105 +/- 94.6 ng/mL, respectively. No significant difference was observed in urinary concentrations of melamine derivatives between cats and dogs. Age and gender were important determinants of the concentrations of the target chemicals in cats and dogs. Cumulative daily intake of melamine and its derivatives was calculated on the basis of urinary concentrations and was found to be 10-500-fold below the tolerable daily intake.

PMID- 29567447 TI - Plant uptake and availability of antimony, lead, copper and zinc in oxic and reduced shooting range soil. AB - Shooting ranges polluted by antimony (Sb), lead (Pb), copper (Cu) and zinc (Zn) are used for animal grazing, thus pose a risk of contaminants entering the food chain. Many of these sites are subject to waterlogging of poorly drained soils. Using field lysimeter experiments, we compared Sb, Pb, Cu and Zn uptake by four common pasture plant species (Lolium perenne, Trifolium repens, Plantago lanceolata and Rumex obtusifolius) growing on a calcareous shooting range soil under waterlogged and drained conditions. To monitor seasonal trends, the same plants were collected at three times over the growing season. Additionally, variations in soil solution concentrations were monitored at three depths over the experiment. Under reducing conditions, soluble Sb concentrations dropped from ~50 MUg L-1 to ~10 MUg L-1, which was attributed to the reduction of Sb(V) to Sb(III) and the higher retention of the trivalent species by the soil matrix. Shoot Sb concentrations differed by a factor of 60 between plant species, but remained at levels <0.3 MUg g-1. Despite the difference in soil solution concentrations between treatments, total Sb accumulation in shoots for plants collected on the waterlogged soil did not change, suggesting that Sb(III) was much more available for plant uptake than Sb(V), as only 10% of the total Sb was present as Sb(III). In contrast to Sb, Pb, Cu and Zn soil solution concentrations remained unaffected by waterlogging, and shoot concentrations were significantly higher in the drained treatment for many plant species. Although showing an increasing trend over the season, shoot metal concentrations generally remained below regulatory values for fodder plants (40 MUg g-1 Pb, 150 MUg g-1 Zn, 15-35 MUg g-1 Cu), indicating a low risk of contaminant transfer into the food chain under both oxic and anoxic conditions for the type of shooting range soil investigated in this study. PMID- 29567449 TI - A Novel QTL qTGW3 Encodes the GSK3/SHAGGY-Like Kinase OsGSK5/OsSK41 that Interacts with OsARF4 to Negatively Regulate Grain Size and Weight in Rice. AB - Grain size and shape are important determinants of grain weight and yield in rice. Here, we report a new major quantitative trait locus (QTL), qTGW3, that controls grain size and weight in rice. This locus, qTGW3, encodes OsSK41 (also known as OsGSK5), a member of the GLYCOGEN SYNTHASE KINASE 3/SHAGGY-like family. Rice near-isogenic lines carrying the loss-of-function allele of OsSK41 have increased grain length and weight. We demonstrate that OsSK41 interacts with and phosphorylates AUXIN RESPONSE FACTOR 4 (OsARF4). Co-expression of OsSK41 with OsARF4 increases the accumulation of OsARF4 in rice protoplasts. Loss of function of OsARF4 results in larger rice grains. RNA-sequencing analysis suggests that OsARF4 and OsSK41 repress the expression of a common set of downstream genes, including some auxin-responsive genes, during rice grain development. The loss-of function form of OsSK41 at qTGW3 represents a rare allele that has not been extensively utilized in rice breeding. Suppression of OsSK41 function by either targeted gene editing or QTL pyramiding enhances rice grain size and weight. Thus, our study reveals the important role of OsSK41 in rice grain development and provides new candidate genes for genetic improvement of grain yield in rice and perhaps in other cereal crops.

AB - Although the association between adverse childhood experiences (ACEs) and adult mental health is becoming well established, less is known about the complex and multiple pathways through which ACEs exert their influence. Growing evidence suggests that adversity early in life conveys not only early impacts, but also augments risk of stress-related life course cascades that continue to undermine health. The present study aims to test pathways of stress proliferation and stress embodiment processes linking ACEs to mental health impairment in adulthood. Data are from the 2011 Behavioral Risk Factor Surveillance Survey, a representative sample of Washington State adults ages 18 and over (N = 14,001). Structural equation modeling allowed for testing of direct and indirect effects from ACEs though low income status, experiences of adversity in adulthood, and social support. The model demonstrated that adult low income, social support and adult adversity are in fact conduits through which ACEs exert their influence on mental health impairment in adulthood. Significant indirect pathways through these variables supported hypotheses that the effect of ACEs is carried through these variables. This is among the first models that demonstrates multiple stress related life course pathways through which early life adversity compromises adult mental health. Discussion elaborates multiple service system opportunities for intervention in early and later life to interrupt direct and indirect pathways of ACE effects. PMID- 29567456 TI - Are negative/unrealistic parent descriptors of infant attributes associated with physical abuse? AB - Parents' perceptions of child behavior influence their responses to the child and may be important predictors of physical abuse. We examined whether infants 12 months of age or younger who were described with negative or developmentally unrealistic words were more likely than other infants to have been physically abused. As part of a prospective observational multicenter study investigating bruising and familial psychosocial characteristics, parents were asked to (1) describe their child's personality, and (2) list three words to describe their child. Four independent raters coded parent responses using a qualitative content analysis, identifying descriptors of infants and classifying each as positive, neutral, or negative/unrealistic. A medical expert panel, blinded to the psychosocial data, separately categorized each case as abuse or accident. We then analyzed the potential association between negative/unrealistic descriptors and abusive injury. Of 185 children enrolled, 147 cases (79%) were categorized as accident and 38 (21%) as abuse. Parents used at least one negative/unrealistic descriptor in 35/185 cases (19%), while the remaining 150 cases (81%) included only positive or neutral descriptors. Of the infants described with negative/unrealistic words, 60% were abused, compared to 11% of those described with positive or neutral words (p < .0001; age group-adjusted OR = 9.95; 95% confidence interval [3.98, 24.90]). Though limited by sample-size, this pilot study informs future work to create a screening tool utilizing negative/unrealistic descriptors in combination with other predictive factors to identify infants at high risk for physical child abuse. PMID- 29567457 TI - Child maltreatment in rural southern counties: Another perspective on race, poverty and child welfare. AB - Building on research that has identified community characteristics associated with child maltreatment, this study investigates the adequacy and equity of the child welfare response at the county level. The study focuses on states in the U.S. south with demographic characteristics that make it possible to disentangle county racial composition from county rurality. County-level child maltreatment data were merged with data from the U.S. Census and other publicly-available sources for the 354 counties in four southern states. Results from multiple regression models indicated that, despite a greater preponderance of risk factors typically associated with child maltreatment, rural, majority African-American counties had lower rates of reported and substantiated child maltreatment compared to other southern counties. Cross-sectional results were consistent across three years: 2012, 2013, and 2014. The findings suggest that children and families in rural, majority African-American counties in the South may not be receiving adequate or equitable responses from the formal child welfare system.

AB - This study describes the synthesis and the biological evaluation of twenty-four original bis(benzyl)spermidines. Structural modifications of the polyamine scaffold were performed in order to avoid easily metabolized bonds. Some bis(benzyl)polyamine derivatives have demonstrated promising activity in vitro against Trypanosoma brucei gambiense and Leishmania donovani. From the enzymatic experiments on trypanothione reductase, we observed that this enzyme was not targeted by our compounds. In vivo evaluation on Swiss mice model infected by T. b. gambiense or L. donovani was done with the most interesting compound of the series. PMID- 29567459 TI - 1-Aroylindoline-hydroxamic acids as anticancer agents, inhibitors of HSP90 and HDAC. AB - A series of 1-aroylindoline-hydroxamic acids have been synthesized in the present study. The results of the biological evaluation led to the identification of compound 12 as dual HDAC6/HSP90 inhibitor. Compound 12 displayed striking inhibitory effects towards the HDAC6 isoform and HSP 90 protein with IC50 values of 1.15 nM (HDAC6) and 46.3 nM (HSP90). Compound 12 also exhibited 113, 139 and 246 fold higher selectivity for HDAC6 over HDAC 1, HDAC 3 and HDAC 8 isoforms and was endowed with significant cytotoxic effects with GI50 values ranging 1.04-1.61 MUM against lung A549, colorectal HCT116, leukemia HL60, and EGFR T790M mutant lung H1975 cell lines. Another interesting finding of the study was substantial cytotoxic effects of compounds particularly against lung H1975 (NSCLC) cell lines with IC50 = 0.26 MUM which may be mediated through HSP90 inhibition. Compound 8 as such was devoid of HDAC inhibitory activity.

AB - OBJECTIVE: To explore differences in the background knowledge of Endometrial Cancer (EC), its risk factors, symptoms and prognosis of Endometrial Cancer (EC) between British White (BW) and British South Asian (BSA) women who had undergone treatment for stage I endometrial cancer within the past 3-years. STUDY DESIGN: Face-to-face, semi-structured interviews exploring knowledge; diagnosis; treatment; follow-up; and survivorship were undertaken and analysed using Thematic Analysis. RESULTS: Twenty-one women were interviewed (13 BW and 8 BSA). BW and BSA women reported similar views, experiences and concerns with regards to EC. Knowledge appeared to differ amongst the two groups with BSA women reporting being more aware that unscheduled vaginal bleeding could be associated with a malignancy but having lower levels of knowledge of the risk factors that can lead to EC, compared to BW women. There was a lack of understanding of the difference between cervical cancer and EC and as a result, many women reported taking reassurance from negative cervical cytology as excluding EC. There was also the misconception amongst some of the women that there was a link between sexual behaviour and EC. Women from both groups used the lay healthcare system to discuss their situation/symptoms, however BSA women reported to have specifically sought out women within their social network who had previously undergone treatment for EC. CONCLUSIONS: Greater effort is needed to raise awareness in both the BW/BSA communities of the symptoms associated with EC that should prompt medical review. Educational efforts are required to overcome the reported perception that EC is synonymous with cervical cancer and cannot be detected by cervical screening. PMID- 29567461 TI - PrEP-001 prophylactic effect against rhinovirus and influenza virus - RESULTS of 2 randomized trials. AB - BACKGROUND: PrEP-001 Nasal Powder, a proprietary formulation of polyriboinosinic and polyribocytidylic acid effectively elicits a cellular innate immune response in nasal epithelium. The aim of these 2 studies was to investigate the safety and efficacy of PrEP-001 prophylaxis against rhinovirus (HRV-A16) and influenza-A (H3N2-IAV). METHODS: Healthy subjects randomly received 2 doses of PrEP-001 or placebo, 48 and 24 h pre-challenge with 10 TCID50 of HRV-A16 (Study 1) or H3N2 IAV (Study 2). RESULTS: In Study 1, PrEP-001 reduced median total symptom score from 38.5 to 4.5 (p = 0.004), median symptom duration from 6.0 to 1.7 days and median mucus production from 15 g to 3 g. The percentage of subjects classified as ill was reduced 3-fold (placebo 73%, PrEP-001 23%, p = 0.002). In Study 2, PrEP-001 reduced median total symptom score from 8.0 to 4.1 (p = 0.021), median symptom duration from 4.6 to 3.7 days and median mucus production from 3.6 g to 1.5 g. The percentage of subjects classified as ill was reduced 2-fold (placebo 48%, PrEP-001 24%, p = 0.064). PrEP-001 reduced peak viral shedding in both studies, as assessed by qRT-PCR of nasal lavage. Seroconversion rates were comparable between placebo and PrEP-001 (Study 1: 77% [both arms]; Study 2: placebo 73%, PrEP-001 80%). PrEP-001 was well-tolerated, with no clinically significant adverse events. CONCLUSIONS: PrEP-001 reduced the number of individuals with clinical illness and attenuated severity and duration of HRV-A16 and H3N2-IAV infections without compromising seroconversion, and was well tolerated. This supports further evaluation of PrEP-001 as a potential pan-viral prophylaxis for upper respiratory tract infections. CLINICAL TRIAL REGISTRATION: Study 1, HRV-A16 study: EudraCT Number 2012-005579-14 (study conducted before ClinicalTrials.gov registration required).

PMID- 29567463 TI - Long-term quality of life of caregivers of cardiac arrest survivors and the impact of witnessing a cardiac event of a close relative. AB - BACKGROUND: The incidence of cardiac arrest is high, with a poor survival rate of 8-14%. Currently, only limited evidence is available about long-term consequences of cardiac arrest on quality of life of caregivers. AIMS: First, to determine the level of daily functioning and quality of life in caregivers of cardiac arrest survivors two years after the cardiac arrest. Second, to study the long-term impact of witnessing the event of a cardiac arrest. METHODS: A longitudinal cohort study including caregivers of cardiac arrest survivors. Participants received a questionnaire at home. Outcome variables were instrumental daily activities(FAI), emotional functioning(HADS), fatigue(FSS), caregiver strain(CSI), impact of event(IES), and quality of life(SF36). RESULTS: 57 caregivers (89% female, age 56,9 +/- 12 years) participated. Two years after the cardiac arrest, quality of life of caregivers equals that of the general population, although almost 30% still scored high on the Impact of Events Scale. Mean IES-, FSS-, CSI and FAI-scores were increased as compared to the general population (P < 0.001). Two years after the cardiac arrest, caregivers that witnessed the resuscitation (IES = 23.6 +/- 14.9) still experienced significantly more trauma related stress than caregivers that did not witness the resuscitation (11.9 +/- 12.5; p < 0.01). CONCLUSIONS: Two years after the cardiac arrest, quality of life of caregivers is quite good, but almost one third of the caregivers still experience a high level of trauma-related stress, especially in those that witnessed the resuscitation. Future research will have to focus on the effectiveness of support programs for caregivers of survivors of cardiac arrest. PMID- 29567464 TI - Parent perspectives on the clinician-client relationship in speech-language treatment for children. AB - Few studies have explored clinician-client relationships in speech-language treatment for children, although evidence indicates that these relationships may be important. Parents play a unique role in clinician-client relationships and their views have yet to be considered in the speech-language pathology literature. This study explored parents' perspectives on the clinician-client relationship in speech-language treatment for children using both quantitative and qualitative information. An online survey collected responses from 159 parents with children enrolled in speech-language services. Respondents were asked to complete a rating of the clinician-client relationship, provide information on length of treatment and treatment setting, and respond to open ended questions about what enhances the clinician-client relationship. Length of treatment was unrelated to the parent rating of the clinician-client relationship. However, ratings did vary by treatment setting; parents of children enrolled in treatment services in schools provided lower ratings than parents with children enrolled in other settings. Thematic analysis of parent views on what enhances the clinician-client relationship yielded four main themes: qualities of the speech-language pathologist (SLP), session characteristics, the child-SLP bond, and communication. The most frequent subthemes in the analysis related to characteristics of the sessions: the integration of play and fun, and a child-oriented approach to sessions. These results provide insight into the development of clinician-client relationships in children's speech-language treatment, with implications for both clinicians and researchers. PMID- 29567465 TI - Perceived listener effort as an outcome measure for disordered speech. AB - PURPOSE: Perceived listening effort is a perceptual dimension used to identify the amount of work necessary to understand disordered speech. The purpose of this study was to investigate the utility of perceived listening effort to provide unique information about disordered speech. The relationships between perceived listening effort and two current outcome measures (speech acceptability, intelligibility) were examined for listeners rating electrolaryngeal speech, along with their reliability and intra-rater agreement. METHODS: Ten healthy male speakers read low-context sentences using an electrolarynx. Twenty-five inexperienced listeners orthographically transcribed and rated the stimuli for perceived listening effort and speech acceptability using a visual analog scale. Strict reliability and agreement criteria were set. RESULTS: Perceived listening effort was moderately to strongly correlated with intelligibility (r = -0.76) and acceptability (r = -0.80), each of which contributed uniquely to ratings of perceived listening effort. However, only 17 listeners met stringent reliability and agreement criteria. CONCLUSIONS: Ratings of perceived listening effort may provide unique information about the communicative success of individuals with communication disorders. There is great variability, however, among inexperienced listeners' perceptual ratings of electrolaryngeal speech. Future research should investigate variables that may affect perceived listening effort specifically and auditory-perceptual ratings in general.

PMID- 29567467 TI - The critical role of p16/Rb pathway in the inhibition of GH3 cell cycle induced by T-2 toxin. AB - T-2 toxin is a worldwide trichothecenetoxin and can cause various toxicities.T-2 toxin is involved in G1 phase arrest in several cell lines but molecular mechanism is still not clear. In present study, we used rat pituitary GH3 cells to investigate the mechanism involved in cell cycle arrest against T-2 toxin (40 nM) for 12, 24, 36 and 48 h as compared to control cells. GH3 cells showed a considerable increase in reactive oxygen species (ROS) as well as loss in mitochondrial membrane potential (?Ym) upon exposure to the T-2 toxin. Flow cytometry showed a significant time-dependent increase in percentage of apoptotic cells and gel electrophoresis showed the hallmark of apoptosis oligonucleosomal DNA fragmentation. Additionally, T-2 toxin-induced oxidative stress and DNA damage with a time-dependent significant increased expression of p53 favors the apoptotic process by the activation of caspase-3 in T-2 toxin treated cells. Cell cycle analysis by flow cytometry revealed a time-dependent increase ofG1 cell population along with the significant time-dependent up-regulation of mRNA and protein expression of p16 and p21 and significant down-regulation of cyclin D1, CDK4, and p-RB levels further verify the G1 phase arrest in GH3 cells. Morphology of GH3 cells by TEM clearly showed the damage and dysfunction to mitochondria and the cell nucleus. These findings for the first time demonstrate that T-2 toxin induces G1 phase cell cycle arrest by the involvement of p16/Rb pathway, along with ROS mediated oxidative stress and DNA damage with p53 and caspase cascade interaction, resulting in apoptosis in GH3 cells. PMID- 29567468 TI - Ants impact the composition of the aquatic macroinvertebrate communities of a myrmecophytic tank bromeliad. AB - In an inundated Mexican forest, 89 out of 92 myrmecophytic tank bromeliads (Aechmea bracteata) housed an associated ant colony: 13 sheltered Azteca serica, 43 Dolichoderus bispinosus, and 33 Neoponera villosa. Ant presence has a positive impact on the diversity of the aquatic macroinvertebrate communities (n=30 bromeliads studied). A Principal Component Analysis (PCA) showed that the presence and the species of ant are not correlated to bromeliad size, quantity of water, number of wells, filtered organic matter or incident radiation. The PCA and a generalized linear model showed that the presence of Azteca serica differed from the presence of the other two ant species or no ants in its effects on the aquatic invertebrate community (more predators). Therefore, both ant presence and species of ant affect the composition of the aquatic macroinvertebrate communities in the tanks of A. bracteata, likely due to ant deposition of feces and other waste in these tanks. PMID- 29567469 TI - Promoting degradation of 2,4-dichlorophenoxyacetic acid with fermentative effluents from hydrogen-producing reactor. AB - This research aims to identifying the potential effect of using a hydrogen producing reactor's effluent as an enrichment amendment for enhancing the degradation rates of 2,4-dichlorophenoxyacetic acid (2,4-D) during the bioremediation of contaminated paddy soils. The results showed that addition of the effluents to 2,4-D- degrading enrichment culture enhanced (up to 1.3-fold) the degradation rate constant of 2,4-D. The enhancement effect most probably resulted from the co-metabolic degradation of 2,4-D facilitated by volatile fatty acids (e.g., acetate, propionate, and butyrate) in the effluents which served as the beneficial substrates. Results from DNA sequencing analysis showed that the effluent additions shifted the bacterial community composition in the enrichment culture. Dechloromonas and Clostridium were two dominant bacterial genera involved in 2,4-D degradation. The findings will make a substantial contribution to remediation of soils contaminated with 2,4-D.

AB - This study is the first attempt to quantify environmental fluxes per capita of organic contaminants discharged from on-site sewage treatment facilities (OSSFs) in affected recipients. Five sites were monitored around the River Fyris in Sweden: three mainly affected by OSSFs and two mainly affected by municipal sewage treatment plants (STPs). Gas chromatography-mass spectrometry was used to determine environmental concentrations of 30 anthropogenic contaminants, including organophosphorus compounds, rubber and plastic additives, UV stabilizers, fragrances, surfactant ingredients and polycyclic aromatic hydrocarbons. Uni- and multivariate statistical analysis of the most frequently detected contaminants showed that median fluxes per capita of tris(1,3-dichloro-2 propyl) phosphate, tris(1-chloro-2-propyl) phosphate, tris(2-chloroethyl) phosphate, and n-butylbenzene sulfonamide were similar at OSSF and STP sites, but the mass fluxes per capita of tris-(2-butoxyethyl) phosphate, 2 (methylthio)benzothiazole, and galaxolide, were significantly lower (~2-3-fold) at OSSF sites than at STP sites (Mann-Whitney, alpha = 0.05). Differences between these sites were larger in samples collected in summer and autumn than in samples collected in winter. Deviations likely originated from differences in fate processes and distances between source and sampling sites. Further studies are needed to characterize mass fluxes per capita of contaminants in waters that directly receive discharges from OSSFs.

AB - Fluoride (F) exposure causes cognitive dysfunction in humans and animals. However, the precise molecular mechanisms by which fluoride exerts its neurotoxic effects are poorly understood. In this study, an animal model of fluoride exposure was created by providing ICR mice were treated with vehicle F at a dose of 0 (control group), 50 (low-fluoride group) or 100 mg/L (high-fluoride group) in water for one month. After the mice mated, parents and offspring were treated and maintained under these conditions. The cognitive abilities of the mice were examined using a Morris water maze test. Results indicated that fluoride exposure significantly prolonged the escape latency period and decreased the number of crossings in a particular zone. Histopathologic analysis revealed the shrinkage and fragmentation of glial cells in the fluoride-treated groups. Pyramidal cells in the cerebral cortices of fluoride-treated groups were fewer than those of the control group. The expression of microtubule-associated protein 2 (MAP2) and synaptic proteins of the cerebral cortex in mouse offspring was assayed using RT PCR and Western blot. Fluoride exposure possibly induced a significantly decreased expression of MAP2, synaptophysin (SYP) and developmentally regulated brain protein (Dbn) at protein and mRNA levels. Glutamate receptor (N-methyl-d aspartate receptor, NMDAR) was also expressed, and this finding was consistent with the reduced MAP2, SYP and Dbn expression. Therefore, fluoride-mediated reduction in cognitive dysfunction is likely caused by the disruption of the expression of these synapse-associated proteins, resulting in attenuated neuronal functioning. PMID- 29567472 TI - SOAT1 deficiency attenuates atherosclerosis by regulating inflammation and cholesterol transportation via HO-1 pathway. AB - Sterol O-acyltransferase 1 (SOAT1) is a key enzyme for cholesteryl ester biosynthesis. The objective of the present study is to investigate the role and underlying molecular mechanisms of SOAT1 in atherosclerosis. Our results indicated that SOAT1 was highly expressed in endothelial cells of atherosclerotic lesions in human patients with atherosclerosis and in apolipoprotein E deficient (ApoE-/-) mice fed with high fat diet (HFD). We established a model of atherosclerosis using ApoE and SOAT1 gene double knockout (ApoE-/-SOAT1-/-) mice. SOAT1-/- alleviated HFD-induced and spontaneously developed atherosclerotic lesions in ApoE-/- mice, accompanied with the reduced triglyceride (TG), total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C), while the enhanced high-density lipoprotein-cholesterol (HDL-C) in serum of ApoE-/- mice. SOAT1-/- decreased collagen accumulation in the lesions. SOAT1-/- reduced macrophage infiltration and suppressed inflammation in ApoE-/- mice fed with HFD, as evidenced by the decreased expressions of pro-inflammatory cytokines, including interleukin (IL)-1beta, IL-6 and tumor necrosis factor alpha (TNF alpha). Of importance, SOAT1-/--attenuated inflammation was along with the inactivation of beta-catenin and nuclear factor kappa B (NF-kappaB) ApoE-/- mice. Moreover, oxidative stress observed in ApoE-/- mice was inactivated by SOAT1 double knockout. In addition, expression levels of fatty acid synthase (FAS), stearoyl-CoA desaturase 1 (SCD1), protein convertase subtilisin/kexin type 9 (PCSK 9) and sterol regulatory element-binding protein-1c (SREBP-1c) were decreased in liver, peritoneal macrophages and abdominal aortas of SOAT1-knockout ApoE-/- mice. In contrast, SOAT1-/- displayed improved expressions of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) and lipoxygenase (LOX)-alpha in liver, peritoneal macrophages and abdominal aortas of ApoE-/- mice. Of note, the in vitro study, oxidized low-density lipoprotein (ox-LDL) incubation reduced heme oxygenase (HO-1) expressions in human umbilical vein endothelial cells (HUVECs), which was improved by SOAT1 knockdown. Pre-treatment of sn protoporphyrin (SnPP), an important HO-1 inhibitor, abolished the role of SOAT1 inhibition in suppressing inflammation and abnormal cholesterol transportation. These results indicated that SOAT1 deficiency protected against atherosclerosis progression via inhibiting cholesterol transportation in ApoE-/- mice, which was, at least partly, dependent on HO-1 expressions. PMID- 29567473 TI - Bruton's tyrosine kinase regulates TLR7/8-induced TNF transcription via nuclear factor-kappaB recruitment. AB - Tumour necrosis factor (TNF) is produced by primary human macrophages in response to stimulation by exogenous pathogen-associated molecular patterns (PAMPs) and endogenous damage-associated molecular patterns (DAMPs) via Toll-like receptor (TLR) signalling. However, uncontrolled TNF production can be deleterious and hence it is tightly controlled at multiple stages. We have previously shown that Bruton's tyrosine kinase (Btk) regulates TLR4-induced TNF production via p38 MAP Kinase by stabilising TNF messenger RNA. Using both gene over-expression and siRNA-mediated knockdown we have examined the role of Btk in TLR7/8 mediated TNF production. Our data shows that Btk acts in the TLR7/8 pathway and mediates Ser 536 phosphorylation of p65 RelA and subsequent nuclear entry in primary human macrophages. These data show an important role for Btk in TLR7/8 mediated TNF production and reveal distinct differences for Btk in TLR4 versus TLR7/8 signalling. PMID- 29567474 TI - Treacher Collins syndrome 3 (TCS3)-associated POLR1C mutants are localized in the lysosome and inhibits chondrogenic differentiation. AB - Treacher Collins syndrome (TCS) is a craniofacial developmental disorder whose key feature is a combination of symptoms. For example, a patient could have bilateral downward slanting of the palpebral fissures, colobomas of the lower eyelids, hypoplasia of the facial bones, cleft palate, malformation of the external ears, and atresia of the external auditory canals. TCS3 is caused by mutations of the polr1c gene, which encodes RNA polymerase I and III subunit C (POLR1C). There have been two known missense mutations (Arg279-to-Gln [R279Q] and Arg279-to-Trp [R279W]) at the Arg-279 position. However, it remains to be clarified whether or how both or each individual mutation affects the cellular properties of POLR1C. Here we show that TCS3-associated missense mutations cause aberrant intracellular localization of POLR1C, inhibiting chondrogenic differentiation. The wild type POLR1C is normally localized in the nuclei. The R279Q or R279W mutant is primarily found to be localized in the lysosome. Expression of the R279Q or R279W mutant in mouse chondrogenic ATDC5 cells decreases phosphorylation of 4E-BP1 and ribosomal S6 proteins, which belong to the mammalian target of rapamycin (mTOR) signaling involved in critical roles in the lysosome. Furthermore, expression of the R279Q or R279W mutant inhibits chondrogenic differentiation in ATDC5 cells. Taken together, TCS3-associated mutation leads to the localization of POLR1C into the lysosome and inhibits chondrogenic differentiation, possibly explaining a portion of the pathological molecular basis underlying Treacher Collins syndrome. PMID- 29567475 TI - Involvement of phosphatidylinositol-3 kinase/Akt/mammalian target of rapamycin/peroxisome proliferator-activated receptor gamma pathway for induction and maintenance of neuropathic pain. AB - Peripheral nerve injury induces neuropathic pain, which is characterized by the tactile allodynia and thermal hyperalgesia. N-type voltage-dependent Ca2+ channel (VDCC) plays pivotal roles in the development of neuropathic pain, since mice lacking Cav2.2, the pore-forming subunit of N-type VDCC, show greatly reduced symptoms of both tactile allodynia and thermal hyperalgesia. Our study on gene expression profiles of the wild-type and N-type VDCC knockout (KO) spinal cord and several pain-related brain regions after spinal nerve ligation (SNL) injury revealed altered expression of genes encoding catalytic subunits of phosphatidylinositol-3 kinase (PI3K). PI3K/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling is considered to be very important for cancer development and drugs targeting the molecules in this pathway have been tested in oncology trials. In the present study, we have tested whether the changes in expression of molecules in this pathway in mice having spinal nerve injury are causally related to neuropathic pain. Our results suggest that spinal nerve injury induces activation of N-type VDCC and the following Ca2+ entry through this channel may change the expression of genes encoding PI3K catalytic subunits (p110alpha and p110gamma), Akt, retinoid X receptor alpha (RXRalpha) and RXRgamma. Furthermore, the blockers of the molecules in this pathway are found to be effective in reducing neuropathic pain both at the spinal and at the supraspinal levels. Thus, the activation of PI3K/Akt/mTOR/peroxisome proliferator activated receptor gamma (PPARgamma) pathway would be a hallmark of the induction and maintenance of neuropathic pain. PMID- 29567476 TI - Thyroid hormone receptor interactor 13 (TRIP13) overexpression associated with tumor progression and poor prognosis in lung adenocarcinoma. AB - Thyroid hormone receptor interactor 13 (TRIP13) is an AAA+-ATPase that plays a key role in mitotic checkpoint complex inactivation and is associated with the progression of several cancers. However, its role in lung adenocarcinogenesis remains unknown. Here, we report that TRIP13 is highly overexpressed in multiple lung adenocarcinoma cell lines and tumor tissues. Clinically, TRIP13 expression is positively associated with tumor size, T-stage, and N-stage, and Kaplan-Meier analysis revealed that heightened TRIP13 expression is associated with lower overall survival. TRIP13 promotes lung adenocarcinoma cell proliferation, clonogenicity, and migration while inhibiting apoptosis and G2/M phase shift in vitro. Accordingly, TRIP13-silenced xenograft tumors displayed significant growth inhibition in vivo. Bioinformatics analysis demonstrated that TRIP13 interacts with a protein network associated with dsDNA break repair and PI3K/Akt signaling. TRIP13 upregulatesAktSer473 and downregulatesAktThr308/mTORSer2448activity, which suppresses accurate dsDNA break repair. TRIP13 also downregulates pro-apoptotic BadSer136 and cleaved caspase-3 while upregulating survivin. In conclusion, heightened TRIP13 expression appears to promote lung adenocarcinoma tumor progression and displays potential as a therapeutic target or biomarker for lung adenocarcinoma. PMID- 29567477 TI - The blocking of aquaporin-3 (AQP3) impairs extravillous trophoblast cell migration. AB - Several aquaporins (AQPs) are expressed in extravillous (EVT) and villous trophoblast cells. Among them, AQP3 is the most abundant AQP expressed in chorionic villi samples from first trimester, followed by AQP1 and AQP9. Although AQP3 expression persists in term placentas, it is significantly decreased in placentas from preeclamptic pregnancies. AQP3 is involved in the migration of different cell types, however its role in human placenta is still unknown. Here, we evaluated the role of AQP3 in the migration of EVT cells during early gestation. Our results showed that Swan 71 cells expressed AQP1, AQP3 and AQP9 but only the blocking of AQP3 by CuSO4 or the silencing of its expression by siRNA significantly attenuates EVT cell migration. Our work provides evidence that AQP3 is required for EVT cell migration and suggests that an altered expression of placental AQP3 may produce failures in placentation such as in preeclampsia. PMID- 29567478 TI - Molecular association model of PPARalpha and its new specific and efficient ligand, pemafibrate: Structural basis for SPPARMalpha. AB - Peroxisome proliferator-activated receptor-alpha (PPARalpha) is a ligand activated transcription factor involved in the regulation of lipid homeostasis and improves hypertriglyceridemia. Pemafibrate is a novel selective PPARalpha modulator (SPPARMalpha) that activates PPARalpha transcriptional activity. Here, we computationally constructed the structure of the human PPARalpha in a complex with pemafibrate, along with that of hPPARalpha complexed with the classical fenofibrate, and studied their interactions quantitatively by using the first principles calculations-based fragment molecular orbital (FMO) method. Comprehensive structural and protein-ligand binding elucidation along with the in vitro luciferase analysis let us to identify pemafibrate as a novel SPPARMalpha. Unlike known fibrate ligands, which bind only with the arm I of the Y-shaped ligand binding pocket, the Y-shaped pemafibrate binds to the entire cavity region. This lock and key nature causes enhanced induced fit in pemafibrate ligated PPARalpha. Importantly, this selective modulator allosterically changes PPARalpha conformation to form a brand-new interface, which in turn binds to PPARalpha co-activator, PGC-1alpha, resulting in the full activation of PPARalpha. The structural basis for the potent effects of pemafibrate on PPARalpha transcriptional activity predicted by the in silico FMO methods was confirmed by in vitro luciferase assay for mutants. The unique binding mode of pemafibrate reveals a new pattern of nuclear receptor ligand recognition and suggests a novel basis for ligand design, offering cues for improving the binding affinity and selectivity of ligand for better clinical consequences. The findings explain the high affinity and efficacy of pemafibrate, which is expected to be in the clinical use soon. PMID- 29567479 TI - Loop engineering reveals the importance of active-site-decorating loops and gating residue in substrate affinity modulation of arginine deiminase (an anti tumor enzyme). AB - Protein engineering of enzyme loop regions is an effective strategy to improve enzymatic properties. Previous studies that aimed to boost the activity of PpADI (an arginine deiminase from Pseudomonas plecoglossicida) under physiological conditions yielded several significantly improved variants that harbor substitutions predominantly located in active-site-decorating loops. A multi-site saturation mutagenesis at four positions in loop 1 (37, 38, 42, and 43) and three positions in loop 4 (402, 403, and 404) was performed to elucidate the importance of these loops in modulating the substrate affinity of PpADI. The identified "best" variant (M6-L1-4) showed a decreased S0.5 ('KM') of 0.48 mM compared with the parent M6 (0.81 mM). Subsequently, a rational design to recombine beneficial substitutions within loops 1 and 4 yielded variant L6 with a substantially decreased S0.5 value (0.17 mM). A comprehensive simulation analysis resulted in a conclusion that high loop flexibility (especially the gating residue Arg400) is beneficial for substrate affinity due to less efficient blocking of the active site. PMID- 29567480 TI - Wnt3 and Gata4 regulate axon regeneration in adult mouse DRG neurons. AB - Neurons in the adult central nervous system (CNS) have a poor intrinsic axon growth potential after injury, but the underlying mechanisms are largely unknown. Wingless-related mouse mammary tumor virus integration site (WNT) family members regulate neural stem cell proliferation, axon tract and forebrain development in the nervous system. Here we report that Wnt3 is an important modulator of axon regeneration. Downregulation or overexpression of Wnt3 in adult dorsal root ganglion (DRG) neurons enhances or inhibits their axon regeneration ability respectively in vitro and in vivo. Especially, we show that Wnt3 modulates axon regeneration by repressing mRNA translation of the important transcription factor Gata4 via binding to the three prime untranslated region (3'UTR). Downregulation of Gata4 could restore the phenotype exhibited by Wnt3 downregulation in DRG neurons. Taken together, these data indicate that Wnt3 is a key intrinsic regulator of axon growth ability of the nervous system. PMID- 29567481 TI - Validation of hindi translation of DSM-5 level 1 cross-cutting symptom measure. AB - BACKGROUND: The DSM-5 Level 1 Cross-Cutting Symptom Measure is a self- or informant-rated measure that assesses mental health domains which are important across psychiatric diagnoses. The absence of this self- or informant-administered instrument in Hindi, which is a major language in India, is an important limitation in using this scale. AIM: To translate the English version of the DSM 5 Level 1 Cross-Cutting Symptom Measure to Hindi and evaluate its psychometric properties. MATERIALS AND METHODS: The study was conducted at a tertiary care hospital in Delhi. The DSM-5 Level 1 Cross-Cutting Symptom Measure was translated into Hindi using the World Health Organization's translation methodology. STATISTICAL ANALYSIS: Mean and standard deviation were evaluated for continuous variables while for categorical variables frequency and percentages were calculated. The translated version was evaluated for cross-language equivalence, test-retest reliability, internal consistency, and split half reliability. RESULTS: Hindi version was found to have good cross-language equivalence and test retest reliability at the level of items and domains. Twenty two of the 23 items and all the 23 items had a significant correlation (rho < 0.001) in cross language concordance and test-retest reliability data, respectively. The Cronbach's alpha was 0.95, and the Spearman-Brown Sphericity value was 0.79 for the Hindi version. CONCLUSION: The present study shows that cross-language concordance, internal consistency, split-half reliability, and test-retest reliability of the Hindi version of the measure are excellent. Thus, the Hindi version of DSM-5 Level 1 Cross-Cutting Symptom Measure as translated in this study is a valid instrument. PMID- 29567482 TI - A vectorized Levenberg-Marquardt model fitting algorithm for efficient post processing of cardiac T1 mapping MRI. AB - PURPOSE: T1 mapping is an emerging MRI research tool to assess diseased myocardial tissue. Recent research has been focusing on the image acquisition protocol and motion correction, yet little attention has been paid to the curve fitting algorithm. METHODS: After nonrigid registration of the image series, a vectorized Levenberg-Marquardt (LM) technique is proposed to improve the robustness of the curve fitting algorithm by allowing spatial regularization of the parametric maps. In addition, a region-based initialization is proposed to improve the initial guess of the T1 value. The algorithm was validated with cardiac T1 mapping data from 16 volunteers acquired with saturation-recovery (SR) and inversion-recovery (IR) techniques at 3T, both pre- and post-injection of a contrast agent. Signal models of T1 relaxation with 2 and 3 parameters were tested. RESULTS: The vectorized LM fitting showed good agreement with its pixel wise version but allowed reduced calculation time (60 s against 696 s on average in Matlab with 256 * 256 * 8(11) images). Increasing the spatial regularization parameter led to noise reduction and improved precision of T1 values in SR sequences. The region-based initialization was particularly useful in IR data to reduce the variability of the blood T1. CONCLUSIONS: We have proposed a vectorized curve fitting algorithm allowing spatial regularization, which could improve the robustness of the curve fitting, especially for myocardial T1 mapping with SR sequences. PMID- 29567483 TI - T-wave end detection using neural networks and Support Vector Machines. AB - BACKGROUND AND OBJECTIVE: In this paper we propose a new approach for detecting the end of the T-wave in the electrocardiogram (ECG) using Neural Networks and Support Vector Machines. METHODS: Both, Multilayer Perceptron (MLP) neural networks and Fixed-Size Least-Squares Support Vector Machines (FS-LSSVM) were used as regression algorithms to determine the end of the T-wave. Different strategies for selecting the training set such as random selection, k-means, robust clustering and maximum quadratic (Renyi) entropy were evaluated. Individual parameters were tuned for each method during training and the results are given for the evaluation set. A comparison between MLP and FS-LSSVM approaches was performed. Finally, a fair comparison of the FS-LSSVM method with other state-of-the-art algorithms for detecting the end of the T-wave was included. RESULTS: The experimental results show that FS-LSSVM approaches are more suitable as regression algorithms than MLP neural networks. Despite the small training sets used, the FS-LSSVM methods outperformed the state-of-the-art techniques. CONCLUSION: FS-LSSVM can be successfully used as a T-wave end detection algorithm in ECG even with small training set sizes. PMID- 29567484 TI - Biomedical image classification based on a cascade of an SVM with a reject option and subspace analysis. AB - Automated biomedical image classification could confront the challenges of high level noise, image blur, illumination variation and complicated geometric correspondence among various categorical biomedical patterns in practice. To handle these challenges, we propose a cascade method consisting of two stages for biomedical image classification. At stage 1, we propose a confidence score based classification rule with a reject option for a preliminary decision using the support vector machine (SVM). The testing images going through stage 1 are separated into two groups based on their confidence scores. Those testing images with sufficiently high confidence scores are classified at stage 1 while the others with low confidence scores are rejected and fed to stage 2. At stage 2, the rejected images from stage 1 are first processed by a subspace analysis technique called eigenfeature regularization and extraction (ERE), and then classified by another SVM trained in the transformed subspace learned by ERE. At both stages, images are represented based on two types of local features, i.e., SIFT and SURF, respectively. They are encoded using various bag-of-words (BoW) models to handle biomedical patterns with and without geometric correspondence, respectively. Extensive experiments are implemented to evaluate the proposed method on three benchmark real-world biomedical image datasets. The proposed method significantly outperforms several competing state-of-the-art methods in terms of classification accuracy. PMID- 29567485 TI - Attachment quality of children with ID and its link to maternal sensitivity and structuring. AB - BACKGROUND: Attachment theory produced a fertile field of research and clinical application. Although the topic of attachment of children with intellectual disability (ID) has received increasing research attention over the past 15 years, the empirical evidence is still limited. AIMS: We applied theoretical and empirical knowledge of parenting typically developing children to examine the mother-child relationship in the ID population. The aim was to examine maternal sensitivity and structuring and its association with children's attachment classification and their disability. METHODS: Forty preschool children (mean age 47.25, range 26-75 months) with non-specific ID and their mothers participated in the study. The mean developmental age was 25.92 months (SD = 10.89), The DQ mean score was 55.45 (SD = 17.28). We assessed children's quality of attachment using the SSP and maternal interactive behavior using the Emotional Availability Scales. OUTCOMES: Forty percent of children showed secure attachment, and 32.5% showed disorganized attachment. Attachment classifications correlated significantly with maternal sensitivity and maternal structuring but not with the child's cognitive disability. CONCLUSIONS: The results point to the importance of maternal interactive behavior for children with ID. Clinical implication may consider interventions aiming to enhance maternal sensitivity and structuring to improve children's quality of attachment. PMID- 29567486 TI - Genetic Evaluation of Cardiomyopathy-A Heart Failure Society of America Practice Guideline. AB - This guideline describes the approach and expertise needed for the genetic evaluation of cardiomyopathy. First published in 2009 by the Heart Failure Society of America (HFSA), the guideline has now been updated in collaboration with the American College of Medical Genetics and Genomics (ACMG). The writing group, composed of cardiologists and genetics professionals with expertise in adult and pediatric cardiomyopathy, reflects the emergence and increased clinical activity devoted to cardiovascular genetic medicine. The genetic evaluation of cardiomyopathy is a rapidly emerging key clinical priority, because high throughput sequencing is now feasible for clinical testing and conventional interventions can improve survival, reduce morbidity, and enhance quality of life. Moreover, specific interventions may be guided by genetic analysis. A systematic approach is recommended: always a comprehensive family history; an expert phenotypic evaluation of the proband and at-risk family members to confirm a diagnosis and guide genetic test selection and interpretation; referral to expert centers as needed; genetic testing, with pre- and post-test genetic counseling; and specific guidance as indicated for drug and device therapies. The evaluation of infants and children demands special expertise. The approach to managing secondary and incidental sequence findings as recommended by the ACMG is provided. PMID- 29567487 TI - Two new species of Gyrodactylus von Nordmann, 1832 from Profundulus oaxacae (Pisces: Profundulidae) from Oaxaca, Mexico, studied by morphology and molecular analyses. AB - In the present study, two new species of Gyrodactylus are described from Profundulus oaxacae, a fish endemic to the Pacific slope of Oaxaca State, Mexico. Fishes were collected within their distribution range in 5 localities in the Atoyac-Verde River. Gyrodactylus montealbani n. sp. and G. zapoteco n. sp. were erected and characterized morphologically (sclerites of the attachment apparatus and the male copulatory organ) and molecularly (sequences of the Internal Transcribed Spacer region of rDNA). The haptoral sclerites of the new species are similar to those of Gyrodactylus iunuri and Gyrodactylus tepari, both recently described from the goodeid fish Goodea atripinnis, from the Mexican States of Jalisco and Queretaro, respectively; and to Gyrodactylus xtachuna described from the poeciliid Poeciliopsis gracilis in Veracruz State, Mexico - nonetheless, these species can all be discriminated based on their marginal hook morphology. Specimens of G. montealbani n. sp. and G. zapoteco n. sp. were sequenced, and were aligned with sequences of 25 other Gyrodactylus spp. Both Maximum likelihood and Bayesian inference analyses indicated that the two new species are members of independent, well-supported lineages - these are the first Gyrodactylus species described from Profundulus oaxacae. PMID- 29567488 TI - Blockade of nuclear factor-kappaB (NF-kappaB) pathway inhibits growth and induces apoptosis in chemoresistant ovarian carcinoma cells. AB - Epithelial ovarian cancer (EOC) has exhibited marginal improvement in survival rate, despite advances in surgical debulking and chemotherapy regimens. Although the majority of EOC patients achieve a clinical remission after induction therapy, over 80% relapse and succumb to chemoresistant disease. In this regard, it is of paramount importance to elucidate molecular mechanisms and signaling pathways which promote therapy resistance in EOC in order to devise novel and more effective treatment strategies. In this study, we showed that activation of nuclear factor-kappaB (NF-kappaB) is significantly higher in therapy-resistant EOC cells compared to chemosensitive counterparts, which was positively associated with resistance to cisplatin, carboplatin, paclitaxel and erlotinib. Bay 11-7082, a highly selective NF-kappaB inhibitor, reduced cell proliferation, clonogenicity and anoikis resistance in the therapy-resistant EOC cells and induced apoptotic cell death. Moreover, Bay 11-7082 decreased the expression of pro-survival, inflammatory and metastatic genes and synergistically increased anti-proliferative efficacy of cisplatin, carboplatin, paclitaxel and erlotinib. Altogether, these findings suggest that NF-kappaB is an attractive therapeutic target in EOC to be exploited in translational oncology and Bay 11-7082 is a potential anti-cancer drug to overcome chemoresistance and inhibit proliferation of the EOC cells. PMID- 29567489 TI - QM/MM analysis of effect of divalent metal ions on OPRT action. AB - The role of Mg2+ cofactor in orotate phosphoribosyltransferase (OPRT) catalyzed synthesis of orotidine monophosphate (OMP) from phosphoribosyl pyrophosphate (PRPP) and orotate (OA) in substrate binding and the influence of the identity of the divalent metal ion on the reaction mechanism were addressed in this study using quantum mechanics/molecular mechanics framework. Energetics of migration and binding of different substrate complexes in the active site cavity was established. A quantitative analysis of various processes indicated the reaction pathway to consist of complexation of Mg2+ with PRPP, migration of Mg2+-PRPP and OA towards the active site, binding of OA to OPRT, and binding of Mg2+-PRPP complex to OA-OPRT complex. The mechanism of the reaction was unaltered by the change in the identity of divalent metal ion. Experimentally reported inhibiting character of Co2+ was explained on the basis of large Co2+-PRPP binding and migration energies. Mg2+, Ca2+, Mn2+, Co2+ and Zn2+ ions were screened computationally to assess their inhibiting/activating characteristics. Trends obtained by our computational investigations were in correspondence with experimentally reported trends. PMID- 29567490 TI - Temperature effect on the structure and conformational fluctuations in two zinc knuckles from the mouse mammary tumor virus. AB - Zinc fingers are small protein domains in which zinc plays a structural role, contributing to the stability of the zinc-peptide complex. Zinc fingers are structurally diverse and are present in proteins that perform a broad range of functions in various cellular processes, such as replication and repair, transcription and translation, metabolism and signaling, cell proliferation, and apoptosis. Zinc fingers typically function as interaction modules and bind to a wide variety of compounds, such as nucleic acids, proteins, and small molecules. In this study, we investigated the structural properties, in solution, of the proximal and distal zinc knuckles of the nucleocapsid (NC) protein from the mouse mammary tumor virus (MMTV) (MMTV NC). For this purpose, we performed a series of molecular dynamics simulations in aqueous solution at 300 K, 333 K, and 348 K. The temperature effect was evaluated in terms of root mean square deviation of the backbone atoms and root mean square fluctuation of the coordinating residue atoms. The stability of the zinc coordination sphere was analyzed based upon the time profile of the interatomic distances between the zinc ions and the chelator atoms. The results indicate that the hydrophobic character of the proximal zinc finger is dominant at 333 K. The low mobility of the coordinating residues suggests that the strong electrostatic effect exerted by the zinc ion on its coordinating residues is not influenced by the increase in temperature. The evolution of the structural parameters of the coordination sphere of the distal zinc finger at 300 K gives us a reasonable picture of the unfolding pathway, as proposed by Bombarda and coworkers (Bombarda et al., 2005), which can predict the binding order of the four conserved ligand-binding residues. Our results support the conclusion that the structural features can vary significantly between the two zinc knuckles of MMTV NC. PMID- 29567491 TI - Adolescent psychopathology in Times of Change: The need for integrating a developmental psychopathology perspective. AB - In addition to the major physical, sexual and cognitive changes, as well as changes in relationships with parents and peers, in recent years adolescents also have to cope with many technological changes and increasing societal instabilities. Most of the existing research has examined the extent to which increasing uncertainties might impact expression of psychopathology and its magnitude. Emerging from a developmental psychopathology perspective, we are looking first for a better understanding of the meaning that adolescents give to these changes, which in turn is likely to affect their behavior. We are also looking for better understanding the importance of the role parents, and other societal systems/institutions (such as peers) play in ameliorating or enhancing the likelihood of maladaptive adolescent behavior under these circumstances. PMID- 29567492 TI - Paternal Cocaine Disrupts Offspring Circadian Clock Function in a Sex-Dependent Manner in Mice. AB - The present study is the first to explore the multigenerational effects of mammalian paternal cocaine intake on offspring (F1) circadian clock regulation. Parental cocaine use poses significant health risks to the offspring, through both maternal and paternal drug influences. With respect to the latter, recent evidence suggests that a paternal mode of cocaine inheritance involves epigenetic germ line actions that can ultimately disrupt offspring behavior. Based on our previous report in mice that free-running circadian period (tau) is chronically lengthened following withdrawal from long-term cocaine treatment, the present study was undertaken to explore potential epigenetic effects of paternal exposure to cocaine over the ~40-day murine spermatogenic cycle on F1 circadian regulatory functions. Here we show that, although withdrawal of sires from the cocaine treatment lengthened their tau, such an effect did not persist in adult F1 male or female offspring born from drug-naive dams. Notably, however, there was a distinct deficit in the ability of F1 cocaine-sired males, but not females, to undergo light-induced phase delay shifts of the circadian clock. In contrast, F1 cocaine-sired females, but not males, had suppressed circadian phase advance shifting responses to two non-photic stimuli: acute i.p. injections of cocaine and the serotonin agonist ([+]8-OH-DPAT). The reduced cocaine shifting in females was not due to suppressed cocaine-induced behavioral arousal. Collectively, these results reveal that a father's cocaine use can disrupt major circadian entrainment mechanisms in his adult progeny in a sex-dependent manner.

AB - Class B G protein-coupled receptors (GPCRs) are important drug targets in many human diseases, including type 2 diabetes, obesity, cardiovascular disease and neurodegeneration. Peptide hormones bind to these receptors through interactions with both the extracellular domain and transmembrane domain. Despite remarkable advances in structural studies of GPCRs, structural characterization of the full length class B receptors remains extremely challenging due to their conformational complexity. The recently solved structures of class B GPCRs reveal the structural basis of peptide ligand recognition and modulation mechanisms of small molecule allosteric modulators. Furthermore, these structures provide essential insights into molecular mechanisms of class B GPCR signal transduction and modulation.

AB - BACKGROUND: Household air pollution (HAP) from combustion of solid fuels is an important contributor to disease burden in low- and middle-income countries (LIC, and MIC). However, current HAP disease burden estimates are based on integrated exposure response curves that are not currently informed by quantitative HAP studies in LIC and MIC. While there is adequate evidence supporting causal relationships between HAP and respiratory disease, large cohort studies specifically examining relationships between quantitative measures of HAP exposure with cardiovascular disease are lacking. OBJECTIVE: We aim to improve upon exposure proxies based on fuel type, and to reduce exposure misclassification by quantitatively measuring exposure across varying cooking fuel types and conditions in diverse geographies and socioeconomic settings. We leverage technology advancements to estimate household and personal PM2.5 (particles below 2.5 MUm in aerodynamic diameter) exposure within the large (N~250,000) multi-country (N~26) Prospective Urban and Rural Epidemiological (PURE) cohort study. Here, we detail the study protocol and the innovative methodologies being used to characterize HAP exposures, and their application in epidemiologic analyses. METHODS/DESIGN: This study characterizes HAP PM2.5 exposures for participants in rural communities in ten PURE countries with >10% solid fuel use at baseline (Bangladesh, Brazil, Chile, China, Colombia, India, Pakistan, South Africa, Tanzania, and Zimbabwe). PM2.5 monitoring includes 48-h cooking area measurements in 4500 households and simultaneous personal monitoring of male and female pairs from 20% of the selected households. Repeat measurements occur in 20% of households to assess impacts of seasonality. Monitoring began in 2017, and will continue through 2019. The Ultrasonic Personal Aerosol Sampler (UPAS), a novel, robust, and inexpensive filter based monitor that is programmable through a dedicated mobile phone application is used for sampling. Pilot study field evaluation of cooking area measurements indicated high correlation between the UPAS and reference Harvard Impactors (r = 0.91; 95% CI: 0.84, 0.95; slope = 0.95). To facilitate tracking and to minimize contamination and analytical error, the samplers utilize barcoded filters and filter cartridges that are weighed pre- and post-sampling using a fully automated weighing system. Pump flow and pressure measurements, temperature and RH, GPS coordinates and semi quantitative continuous particle mass concentrations based on filter differential pressure are uploaded to a central server automatically whenever the mobile phone is connected to the internet, with sampled data automatically screened for quality control parameters. A short survey is administered during the 48-h monitoring period. Post-weighed filters are further analyzed to estimate black carbon concentrations through a semi-automated, rapid, cost-effective image analysis approach. The measured PM2.5 data will then be combined with PURE survey information on household characteristics and behaviours collected at baseline and during follow-up to develop quantitative HAP models for PM2.5 exposures for all rural PURE participants (~50,000) and across different cooking fuel types within the 10 index countries. Both the measured (in the subset) and the modelled exposures will be used in separate longitudinal epidemiologic analyses to assess associations with cardiopulmonary mortality, and disease incidence. DISCUSSION: The collected data and resulting characterization of cooking area and personal PM2.5 exposures in multiple rural communities from 10 countries will better inform exposure assessment as well as future epidemiologic analyses assessing the relationships between quantitative estimates of chronic HAP exposure with adult mortality and incident cardiovascular and respiratory disease. This will provide refined and more accurate exposure estimates in global CVD related exposure response analyses.

AB - Lignocellulose is considered a major source for the production of valuable chemicals. Efficient degradation of lignin as the natural carrier of the lignocellulosic biomass represents a key limiting factor in biomass digestibility. Recently, biological delignification methods have been promoted as sustainable and environmentally friendly alternatives to the traditional technologies. In this study, porous nanocomposite of Fe3O4@SiO2@KIT-6 with magnetic properties was synthesized. The immobilized laccase supported on nanocomposite with enhanced stability in a hydrophobic ionic liquid has been developed for both olive pomace delignification and degradation of phenolic extracts from the pomace. After 6h incubation, the degradation rate of lignin and phenol by the immobilized laccase was estimated to be 77.3% and 76.5%, respectively. The immobilized laccase retained 70% of its initial degradation ability after 11 successive batch treatments of olive pomace. Furthermore, the immobilized laccase retained >70% of its initial activity after 21days of storage at room temperature. The obtained results indicated that the immobilized laccase on magnetic mesoporous support together with (1-Butyl-3-methylimidazolium hexafluorophosphate) ([Bmim][PF6]) could potentially provide a promising procedure for an improved enzymatic degradation of lignin and phenol in the related industries. PMID- 29567497 TI - Biocatalytic action of proteases in ionic liquids: Improvements on their enzymatic activity, thermal stability and kinetic parameters. AB - This study evaluated the effect of the addition of the following ionic liquids (IL): choline chloride (CC), tetramethylammonium bromide (TB) and 1-ethyl-3 methylimidazolium bromide (EM), on some biochemical properties including enzymatic activity and different kinetic parameters of commercial proteases. The enzyme-IL combinations that showed the highest increases in enzyme activities were as follows: CC (0.5mM) and Neutrase(r) 0.8L; CC (5mM) and Flavourzyme(r) 500L; TB (2000mM) and Alcalase(r) 2.4L, with relative increases of 20, 15 and 150% in protease activities, respectively, compared to the control assays. The combination TB and Alcalase(r) 2.4L showed a reduction of 50% of the activation energy (Ea), an increase of the relation Vmax/Km of 35% and a 16-fold rise in the values of t1/2, and D. Neutrase(r) 0.8L combined with CC showed an increase of 20% in the relation Vmax/Km. The combination Flavourzyme(r) 500L and CC presented a 20% higher value of the relation Vmax/Km and a 2-fold increase in the values of t1/2 and D compared to the control assay. In summary, the most positive effects observed in this study included proteases with improved activity and stability properties and a greater affinity for the substrate.

AB - Development of tamarind seed gum (TSG)-hydrolyzed polymethacrylamide-g-gellan (h Pmaa-g-GG) composite beads for extended release of diclofenac sodium using 32 full factorial design is the main purpose of this study. The ratio of h-Pmaa-g-GG and TSG and concentration of cross-linker CaCl2 were taken as independent factors with three different levels of each. Effects of polymer ratio and CaCl2 on drug entrapment efficiency (DEE), drug release, bead size and swelling were investigated. Responses such as DEE and different drug release parameters were statistically analyzed by 32 full factorial design using Design-Expert software and finally the formulation factors were optimized to obtain USP-reference release profile. Drug release rate was found to decrease with decrease in the ratio of h-Pmaa-g-GG:TSG and increase in the concentration of Ca2+ ions in cross linking medium. The optimized formulation showed DEE of 93.25% and an extended drug release profile over a period of 10h with f2=80.13. Kinetic modeling unveiled case-I-Fickian diffusion based drug release mechanism. PMID- 29567499 TI - Redox responsive curcumin-loaded human serum albumin nanoparticles: Preparation, characterization and in vitro evaluation. AB - The purpose of this study was to fabricate redox-responsive human serum albumin (HSA) nanoparticles (NPs) through self-assembly of HSA molecules for incorporation of curcumin (CCM) as a hydrophobic drug molecule. The structural changes of HSA in self-assembly process of nanoparticle formation were investigated using fluorescence, UV-vis, circular dichroism spectroscopy and X ray diffraction. Spectroscopy data show changes in secondary and tertiary structures of HSA in the process of nanoparticle formation, which can be indicative of the interaction of the hydrophobic drug with HSA molecules. Unlike free CCM, nanoparticulate curcumin is readily dispersed in aqueous medium. Furthermore, self-assembled HSA-CCM NPs release CCM in an environment imitating the intracellular environment with the trigger of acidic pH and redox potential. The in vitro release studies showed that at pH7.4 only 26% CCM was released from CCM-loaded HSA NPs in 48h. However, the release of CCM was significantly accelerated in the presence of 10mM glutathione (GSH) at pH7.4 or pH5.5, in which 57% and 70% of CCM was released, respectively. The incorporation of CCM in HSA nanoparticles enhanced the cellular uptake of CCM in comparison with free CCM results in higher anticancer efficacy against MCF-7 cells. PMID- 29567500 TI - Enhanced activity and stability of papain by covalent immobilization on porous magnetic nanoparticles. AB - Papain enzyme was successfully immobilized by covalent bonding onto biocompatible Fe3O4/SF nanoparticles, which were prepared with the soft template of silk fibroin (SF). The optimized immobilization condition is pH6.0, hydrolysis time of 60min, and an enzyme/support ratio of 10.0mg/g. Compared with free papain, the immobilized papain exhibits a high effective activity, broader working pH and temperature. This immobilized papain can be separated from the solution by the external magnetic field for cyclic utilization, and 70% of initial activity was retained after eight consecutive operations while completely loss of proteolytic activity for the free papain. Furthermore, the immobilized papain maintained 85% of their initial activity after being stored for 28days. Kinetic parameters, maximum reaction rate (Vmax) and Michaelis constant (Km) of immobilized papain, were determined as 4.95mg/l.min and 0.23mg/ml, larger than its free counterpart. All the results above indicated that the immobilized papain onto magnetic Fe3O4/SF nanoparticles would have potential industrial and medical applications. PMID- 29567501 TI - The role of probiotic Lactobacillus acidophilus ATCC 4356 bacteriocin on effect of HBsu on planktonic cells and biofilm formation of Bacillus subtilis. AB - : Bacillus subtilis is a Gram positive, aerobic and motile bacterium. Biofilm formation is an important feature of this bacterium which confers resistance to antimicrobial agents. The use of new antimicrobial reagents which eliminate biofilms are important and necessary. In this study, the effect of secondary metabolites (bacteriocin) from Lactobacillus acidophilus ATCC 4356 on Bacillus subtilis BM19 in the presence and absence of HBsu which is involved in the growth of planktonic cells and biofilm formation, is reported. HBsu nucleoprotein plays several roles in different processes of Bacillus subtilis cells such as replication, transcription, cell division, recombination and repair. In this study, for the first time, the effect of HBsu on biofilm formation is presented. RESULTS: In the absence of HBsu, purified bacteriocin from L. acidophilus ATCC 4356 was more effective in inhibiting growth of B. subtilis BM19 planktonic cells as well as biofilm formation. The presence of HBsu on the other hand led to increased biofilm formation. PMID- 29567502 TI - Early cross-modal interactions underlie the audiovisual bounce-inducing effect. AB - Two identical visual disks moving towards one another on a two-dimensional display can be perceived as either "streaming through" or "bouncing off" each other after their coincidence/overlapping. A brief sound presented at the moment of the coincidence of the disks could strikingly bias the percept towards bouncing, which was termed the audiovisual bounce-inducing effect (ABE). Although the ABE has been studied intensively since its discovery, the debate about its origin is still unresolved so far. The present study used event-related potential (ERP) recordings to investigate whether or not early neural activities associated with cross-modal interactions play a role on the ABE. The results showed that the fronto-central P2 component ~200 ms before the coincidence of the disks was predictive of subsequent streaming or bouncing percept in the unimodal visual display but not in auditory-visual display. More importantly, the cross-modal interactions revealed by the fronto-central positivity PD170 (125-175 ms after sound onset), as well as the occipital positivity PD190 (180-200 ms), were substantially enhanced on bouncing trials compared to streaming trials in the auditory-visual display. These findings provide direct electrophysiological evidence that early cross-modal interactions contribute to the origin of ABE phenomenon at the perceptual stage of processing. PMID- 29567503 TI - Transcriptomic characterization of MRI contrast with focus on the T1-w/T2-w ratio in the cerebral cortex. AB - Magnetic resonance (MR) images of the brain are of immense clinical and research utility. At the atomic and subatomic levels, the sources of MR signals are well understood. However, we lack a comprehensive understanding of the macromolecular correlates of MR signal contrast. To address this gap, we used genome-wide measurements to correlate gene expression with MR signal intensity across the cerebral cortex in the Allen Human Brain Atlas (AHBA). We focused on the ratio of T1-weighted and T2-weighted intensities (T1-w/T2-w ratio image), which is considered to be a useful proxy for myelin content. As expected, we found enrichment of positive correlations between myelin-associated genes and the ratio image, supporting its use as a myelin marker. Genome-wide, there was an association with protein mass, with genes coding for heavier proteins expressed in regions with high T1-w/T2-w values. Oligodendrocyte gene markers were strongly correlated with the T1-w/T2-w ratio, but this was not driven by myelin-associated genes. Mitochondrial genes exhibit the strongest relationship, showing higher expression in regions with low T1-w/T2-w ratio. This may be due to the pH gradient in mitochondria as genes up-regulated by pH in the brain were also highly correlated with the ratio. While we corroborate associations with myelin and synaptic plasticity, differences in the T1-w/T2-w ratio across the cortex are more strongly linked to molecule size, oligodendrocyte markers, mitochondria, and pH. We evaluate correlations between AHBA transcriptomic measurements and a group averaged T1-w/T2-w ratio image, showing agreement with in-sample results. Expanding our analysis to the whole brain results in strong positive T1-w/T2-w correlations for immune system, inflammatory disease, and microglia marker genes. Genes with negative correlations were enriched for neuron markers and synaptic plasticity genes. Lastly, our findings are similar when performed on T1-w or inverted T2-w intensities alone. These results provide a molecular characterization of MR contrast that will aid interpretation of future MR studies of the brain. PMID- 29567505 TI - The effect of missing data on coalescent species delimitation and a taxonomic revision of whipsnakes (Colubridae: Masticophis). AB - A stable alpha taxonomy is essential to understanding evolutionary processes and achieving effective conservation aims. Taxonomy depends on the identification of independently evolving lineages, and the delimitation of these lineages based on multiple lines of evidence. Coalescent species delimitation within an integrative framework has increased the rigor of the delimitation process. Here we use genome wide SNP data and coalescent species delimitation to explore lineage relationships within several North American whipsnake species, test the species status of several lineages, and test the effect of missing data on species delimitation. We find support for the elevation of several previously recognized subspecies to full species status, and formally elevate two species. This study demonstrates the power of molecular data and model-based delimitation methods to identify evolutionary relationships, and finds that missing data have little impact on the outcome of delimitation analyses. PMID- 29567504 TI - Age-related changes in cerebrovascular reactivity and their relationship to cognition: A four-year longitudinal study. AB - Although cerebrovascular factors are the second leading cause of cognitive impairment and dementia in elderly, the precise spatial and temporal trajectories of vascular decline in aging have not been fully characterized. With an advanced cerebrovascular reactivity (CVR) MRI technique that specifically informs vascular stiffness and dilatory ability of cerebral vessels, we present four-year longitudinal CVR data measured in 116 healthy individuals (20-88 years of age). Our data revealed a spatial heterogeneity in vascular decline in aging (p = 0.003), in that temporal lobe showed the fastest rate of longitudinal CVR decline, followed by parietal and frontal lobes. The rate of CVR decline was also age-dependent. Middle age, not older age, manifested the fastest rate of longitudinal CVR decline (p < 0.05). Longitudinal changes in CVR were associated with changes in processing speed (p = 0.031) and episodic memory (p = 0.022), but not with working memory or reasoning. The rate of longitudinal CVR change was not different between hypertensive and normotensive participants. However, cross sectionally, individuals with hypertension revealed in a lower CVR compared to normotensive participants (p = 0.016). These findings help elucidate age-related decline in brain hemodynamics and support CVR as a non-invasive biomarker in evaluating cerebrovascular conditions in elderly individuals. PMID- 29567506 TI - Phylogeny of the subfamily Stelliferinae suggests speciation in Ophioscion Gill, 1863 (Sciaenidae: Perciformes) in the western South Atlantic. AB - Phylogenies based on morphological and molecular data confirm the monophyly of the subfamily Stelliferinae; however, there is no consensus on the intergeneric and interspecific relationships in the group. Previous studies suggested the non monophyly of Ophioscion and Stellifer, and possible cryptic species in Ophioscion punctatissimus. Therefore, we used mitochondrial (16S rDNA and COI) and nuclear (Rhodopsin, EGR1, and RAG1) regions to examine phylogenetic relationships among species of this subfamily. Our results confirmed the monophyly of Stelliferinae and supports the close relationship among Bardiella, Corvula and Odontoscion, which form a sister group to Stellifer and Ophioscion. Notwithstanding, all the results support the non-monophyly of Stellifer and Ophioscion and we suggest that a taxonomic revision should consider Ophioscion as a junior synonym of Stellifer. Moreover, O. punctatissimus was grouped into two clades, with the O. punctatissimus lineage I (LI) being closer to O. scierus from the eastern Pacific than to the O. punctatissimus lineage II (LII). The most recent common ancestor (TMRCA) for the O. scierus and O. punctatissimus LI and O. punctatissimus LII clade dates from 7.2 (HPD: 4.3-10.5) Ma, whereas TMRCA for the O. scierus and O. punctatissimus LI clade dates from 5.3 (HPD: 2.4-8.6) Ma, indicating that speciation processes may be related to the rise of the Isthmus of Panama. Phylogeographic analyses corroborate the hypothesis of speciation in O. punctatissimus. These results suggest that lineages of O. punctatissimus originated from distinct ancestors and, by morphological similarity, were considered the same taxon. A taxonomic revision should be performed to validate the species status of such lineages. PMID- 29567507 TI - Acceptability of latent tuberculosis testing of migrants in a college environment in England. AB - OBJECTIVES: The majority of tuberculosis (TB) cases in England occur from reactivation of latent tuberculosis infection (LTBI) in the settled migrant population. The National Institute for Health and Clinical Excellence recommends that new entrants from high-incidence countries are screened to detect LTBI. This article seeks to describe an outreach programme and testing for LTBI in an innovative setting-ESOL (English for Speakers of Other Languages) classes at a community college (CC) with evaluation of acceptability. STUDY DESIGN: Partnership working with mixed methods used for evaluation of acceptability. METHODS: A pre-existing network from the local TB partnership designed an outreach intervention and screening for LTBI among students from an ESOL programme at a CC. Screening for LTBI with interferon gamma release assay was the culmination of a programme of health improvement activities across the college. Any student on the ESOL programme younger than the age of 35 years and resident in the UK for less than 5 years was eligible for testing. LTBI testing was carried out on-site, and the experience was evaluated by questionnaires to staff, students and partners. A facilitated debrief among the partners gave further data. RESULTS: A total of 440 eligible students were tested. One hundred and seventy-two student feedback questionnaires were completed, and 36 partner questionnaires were received with 18 CC staff responding. Students, tutors and healthcare professionals found the setting acceptable with some concerns about insufficient resource for timely follow-up. CONCLUSIONS: Students, tutors, community organisations and health professionals found the exercise worthwhile and the method and setting acceptable. There were resource issues for the clinical team in follow-up of students with positive results for such a large screening event. Unexpected barriers were found by the CC as this kind of activity was not recognised for external quality review purposes. There were concerns about reputational loss and stigma of being involved in a TB project. As current initiatives aim to divert workload from stretched general practice surgeries, this may be an important addition to primary care screening. PMID- 29567508 TI - Ectopic expression of SaNRAMP3 from Sedum alfredii enhanced cadmium root-to-shoot transport in Brassica juncea. AB - SaNRAMP3 gene cloned from a Zn/Cd hyperaccumulator Sedum alfredii was ectopicly expressed in Brassica juncea, a fast-growing and high-biomass crop plant. In a tissue culture experiment, transgenic plants were grown on MS medium with 0, 25, 50, 100, 200 MUM Cd. It was shown that, at the same Cd treatment, the Cd tolerance of transgenic plants had no significant difference with those of wild type plants (WT). However, the shoot Cd content and accumulation were improved significantly while the root Cd content and accumulation were descended significantly by SaNRAMP3 gene expression, which obviously enhanced the Cd root to-shoot translocation factor (TF). In the hydroponic experiment, plants were cultured in nutrition solution with 0, 2.5, 25 MUM Cd. Data showed that the Cd tolerance of transgenic plants had no significant difference with that of WT under the same Cd exposure. Whereas, the shoot Cd content and accumulation was increased 1.43-1.81 times and the TF was enhanced 3.09-3.51 times by SaNRAMP3 gene expression. Those results indicated that ectopic expression of SaNRAMP3 in B. juncea didn't lead to Cd sensitivity, but enhanced Cd root-to-shoot transport, so that increased shoot Cd accumulation. This study provided a possibility to improve phytoextraction efficiency of heavy metal through gene engineering. PMID- 29567509 TI - Effect of graphene oxide on the bioactivities of nitrifying and denitrifying bacteria in aerobic granular sludge. AB - With the widespread application of graphene oxide (GO), it would be inevitably released into wastewater treatment plants (WWTPs) and get involved in the biochemical process. So far, there are controversies on the effects of low GO concentration (0.05-0.1 g/L) on the nitrogen removal process. Therefore, this study essentially investigates any potential effects of GO on wastewater microbial communities functions. In present study, the nitrifying and denitrifying batch tests were introduced to investigate the influence of 0.06 g/L of GO on bacteria. The results showed that GO could be easily combined with the aerobic granular sludge (AGS), and NH4+-N was sharply absorbed, which directly promoted the bioactivities of ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) and extracellular polymeric substances (EPS) production. The influence of GO on the denitrifying bacteria was negligible, which resulted in the stable EPS production. Furthermore, as inferred from the near maximum chemical reaction rates, there were no obvious changes on the microbial community functions during nitrogen removal process. PMID- 29567511 TI - The transition from HLA-I positive to HLA-I negative primary tumors: the road to escape from T-cell responses. AB - MHC/HLA class I loss in cancer is one of the main mechanisms of tumor immune escape from T-cell recognition and destruction. Tumor infiltration by T lymphocytes (TILs) and by other immune cells was first described many years ago, but has never been directly and clearly linked to the destruction of HLA-I positive and selection of HLA-I negative tumor cells. The degree and the pattern of lymphocyte infiltration in a tumor nest may depend on antigenicity and the developmental stages of the tumors. In addition, it is becoming evident that HLA I expression and tumor infiltration have a direct correlation with tumor tissue reorganization. We observed that at early stages (permissive Phase I) tumors are heterogeneous, with both HLA-I positive and HLA-negative cancer cells, and are infiltrated by TILs and M1 macrophages as a part of an active anti-tumor Th1 response. At later stages (encapsulated Phase II), tumor nests are mostly HLA-I negative with immune cells residing in the peri-tumoral stroma, which forms a granuloma-like encapsulated tissue structure. All these tumor characteristics, including tumor HLA-I expression pattern, have an important clinical prognostic value and should be closely and routinely investigated in different types of cancer by immunologists and by pathologists. In this review we summarize our current viewpoint about the alterations in HLA-I expression in cancer and discuss how, when and why tumor HLA-I losses occur. We also provide evidence for the negative impact of tumor HLA-I loss in current cancer immunotherapies, with the focus on reversible ('soft') and irreversible ('hard') HLA-I defects. PMID- 29567512 TI - The effects of one night of partial sleep deprivation on executive functions in individuals reporting chronic insomnia and good sleepers. AB - BACKGROUND AND OBJECTIVES: The aim of the present study was to investigate the effects of a partial sleep deprivation night on executive functions in participants reporting chronic insomnia and good sleepers using a Task Switching paradigm. METHODS: Sixteen participants reporting symptoms of chronic insomnia and sixteen good sleepers were tested after a night of habitual sleep and after a night of partial sleep deprivation (5 h of sleep allowed). The Switch Cost (SC) and the Backward Inhibition (BI) were computed as measures of switching attention and response inhibition, respectively. RESULTS: We observed a marginally significant interaction Night * Group on SC (F(1,29) = 4.06, p = 0.053), eta2 = 0.123. Fisher's least significant difference (LSD) post-hoc revealed a smaller SC after the sleep deprived night relative to the habitual night for the good sleepers (p = 0.027; M = 192.23 +/- 201.81 vs M = 98.99 +/- 141.16). Differently, participants with insomnia did not show any change after the two nights. LIMITATIONS: Several limitations must be acknowledged including the use of a convenient sample of university students and the use of a single task of cognitive performance. CONCLUSIONS: We found that SC was smaller in the good sleepers after a night of partial sleep deprivation compared to a habitual night, indicating a better switching performance. The insomnia group showed no differences in performance after the two experimental nights. Several factors may account for these results, including increased levels of arousal and cognitive effort during task execution.

AB - Eight adonilide (14,20alpha-epoxy-3beta,20-dihydroxy-14beta-pregn-5-en-18-oic acid gamma-lactone) glycosides, named aestivalosides A-H, and four glycosides of the adonilide derivatives, named aestivalosides I-L, were isolated from the MeOH extract of seeds of Adonis aestivalis. Aestivalosides A-L were previously undescribed compounds, and were structurally characterized using spectroscopic techniques, including two-dimensional NMR, and chemical methods. PMID- 29567510 TI - The effects of early life stress on reward processing. AB - Early life stress (ELS), in the form of childhood maltreatment, abuse, or neglect, increases the risk for psychiatric sequelae later in life. The neurobiology of response to early stress and of reward processing overlap substantially, leading to the prediction that reward processing may be a primary mediator of the effects of early life stress. We describe a growing body of literature investigating the effects of early life stressors on reward processing in animals and humans. Despite variation in the reviewed studies, an emerging pattern of results indicates that ELS results in deficits of ventral striatum related functions of reward responsiveness and approach motivation, especially when the stressor is experienced in early in development. For stressors experienced later in the juvenile period and adolescence, the animal literature suggests an opposite effect, in which ELS results in increased hedonic drive. Future research in this area will help elucidate the transdiagnostic impact of early life stress, and therefore potentially identify and intervene with at-risk youth, prior to the emergence of clinical psychopathology. PMID- 29567514 TI - Development of an anti-dengue NS1 IgG ELISA to evaluate exposure to dengue virus. AB - Dengue virus infection elicits immune responses to multiple viral antigens including antibodies to dengue non-structural protein 1 (NS1) which are rapidly induced and detected within days of infection. The recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV; Sanofi Pasteur) uses the yellow fever vaccine virus as a back-bone but expresses dengue virus pre-membrane and envelop proteins. Since CYD-TDV does not express dengue NS1, we evaluated the utility of dengue NS1-specific IgG antibodies as biomarkers of dengue exposure in CYD-TDV recipients and controls. We optimized and evaluated a quantitative anti-dengue NS1 IgG enzyme-linked immunosorbent assay (ELISA). Parameters assessed included: accuracy, dilutability/linearity, precision, limit of quantitation and specificity. The assay specificity was further evaluated using Japanese Encephalitis virus, West Nile virus, Yellow Fever virus or Zika virus positive sera samples collected following confirmed infection or vaccination. Receiver operating-characteristics (ROC) curves as well as sensitivity and specificity for discriminating previous dengue exposure were assessed using 1250 reference samples. Overall, the anti-dengue NS1 IgG ELISA was able to discriminate previous dengue exposure from non-exposure before vaccination with CYD-TDV (ROC area under the curve > 0.9). Assessment of paired samples from 2511 vaccinated participants showed high overall agreement (93%) between pre-vaccination and post-vaccination dengue serostatus classification based on the anti-dengue NS1 IgG ELISA. However, misclassification of dengue serostatus was observed after vaccination likely due to a combination of asymptomatic dengue infections, assay variability and a modest effect of CYD-TDV on the anti-dengue NS1 IgG ELISA readout. PMID- 29567515 TI - In-hospital complication rate following microendoscopic versus open lumbar laminectomy: a propensity score-matched analysis. AB - BACKGROUND CONTEXT: The incidence of postoperative complications after microendoscopic laminectomy (MEL) has not been compared with that after open laminectomy in a large study, so it is not clear whether MEL is a safer procedure. PURPOSE: The objective of this study was to compare postoperative morbidity and mortality following lumbar laminectomy between patients treated with MEL and with open laminectomy. STUDY DESIGN: This is a retrospective cohort study with propensity score-matched analysis. PATIENT SAMPLE: Data of patients who underwent elective spinal surgery between July 2010 and March 2013 were extracted from the Diagnosis Procedure Combination database, a nationwide inpatient database in Japan. OUTCOME MEASURES: Clinical outcomes included length of hospital stay, occurrence of major complications (cardiac events, respiratory complications, pulmonary embolism, stroke, and acute renal failure), surgical site infection (SSI), postoperative delirium, and in-hospital death. MATERIALS AND METHODS: Propensity score matching was performed to adjust for measured confounding factors, including patient age, sex, Charlson Comorbidity Index, body mass index, smoking status, blood transfusion, duration of anesthesia, number of operated disc levels, and type of hospital and hospital volumes. The clinical outcomes of one-to-one propensity-matched pairs of the MEL and the open laminectomy groups were compared. RESULTS: Of 23,317 patients identified in the database, 1,536 underwent MEL (6.6%). By one-to-one propensity score matching, 1,536 pairs were selected. The distributions of patient backgrounds were closely balanced between the MEL and the open laminectomy groups. An analysis of 1,536 pairs revealed that there was a significantly lower incidence of major postoperative complications in those who underwent MEL (1.0% vs. 2.8% for open laminectomy, risk difference 1.8%, 95% confidence interval [CI] 0.9%-2.9%), SSI (0.5% vs. 1.6% for open laminectomy, risk difference 1.1%, 95% CI 0.4%-1.9%), and postoperative delirium (1.1% vs. 2.3% for open laminectomy, risk difference1.2%, 95% CI 0.3%-2.1%). The length of hospital stay was significantly shorter in those treated with MEL (12 days vs. 16 days for open laminectomy, p<.001). There was no significant difference in in-hospital mortality between the groups. CONCLUSIONS: Patients who underwent MEL were significantly less likely to experience major postoperative complications and were less likely to develop SSI and postoperative delirium than those who underwent open laminectomy. PMID- 29567516 TI - Predicting survival for metastatic spine disease: a comparison of nine scoring systems. AB - BACKGROUND CONTEXT: Despite advances in spinal oncology, research in patient based prognostic calculators for metastatic spine disease is lacking. Much of the literature in this area investigates the general predictive accuracy of scoring systems in heterogeneous populations, with few studies considering the accuracy of scoring systems based on patient specifics such as type of primary tumor. PURPOSE: The aim of the present study was to compare the ability of widespread scoring systems to estimate both overall survival at various time points and tumor-specific survival for patients undergoing surgical treatment for metastatic spine disease in order to provide surgeons with information to determine the most appropriate scoring system for a specific patient and timeline. STUDY DESIGN: This is a retrospective study. PATIENT SAMPLE: Patients who underwent surgical resection for metastatic spine disease at a single institution were included. OUTCOME MEASURES: Areas under the receiver operating characteristic curves were generated from comparison of actual survival of patients and survival as predicted by application of prevalent scoring systems. METHODS: A preoperative score for all 176 patients was retrospectively calculated utilizing the Skeletal Oncology Research Group (SORG) Classic Scoring Algorithm, SORG Nomogram, original Tokuhashi, revised Tokuhashi, Tomita, original Bauer, modified Bauer, Katagiri, and van der Linden scoring systems. Univariate and multivariate Cox proportional hazard models were constructed to assess the association of patient variables with survival. Receiver operating characteristic analysis modeling was utilized to quantify the accuracy of each test at different end points and for different primary tumor subgroups. No funds were received in support of this work. The authors have no conflicts of interest to disclose. RESULTS: Among all patients surgically treated for metastatic spine disease, the SORG Nomogram demonstrated the highest accuracy at predicting 30-day (area under the curve [AUC] 0.81) and 90-day (AUC 0.70) survival after surgery. The original Tokuhashi was the most accurate at predicting 365-day survival (AUC 0.78). Multivariate analysis demonstrated multiple preoperative factors strongly associated with survival after surgery for spinal metastasis. The accuracy of each scoring system in determining survival probability relative to primary tumor etiology and time elapsed since surgery was assessed. CONCLUSIONS: Among the nine scoring systems assessed, the present study determined the most accurate scoring system for short term (30-day), intermediate (90-day), and long-term (365-day) survival, relative to primary tumor etiology. The findings of the present study may be utilized by surgeons in a personalized effort to select the most appropriate scoring system for a given patient. PMID- 29567517 TI - Biomechanical comparative study of the stability of injectable pedicle screws with different lateral holes augmented with different volumes of polymethylmethacrylate in osteoporotic lumbar vertebrae. AB - BACKGROUND CONTEXT: Polymethylmethacrylate (PMMA) is widely used for pedicle screw augmentation in osteoporosis. Until now, there had been no studies of the relationship between screw stability and the distribution and volume of PMMA. PURPOSE: The objective of this study was to analyze the relationship between screw stability and the distribution pattern and injected volume of PMMA. STUDY DESIGN: This is a biomechanical comparison of injectable pedicle screws with different lateral holes augmented with different volumes of PMMA in cadaveric osteoporotic lumbar vertebrae. METHODS: Forty-eight osteoporotic lumbar vertebrae were randomly divided into Groups A, B, and C with different pedicle screws (16 vertebrae in each group), and then each group was randomly divided into Subgroups 0, 1, 2, and 3 with different volumes of PMMA (four vertebra with eight pedicles in each subgroup). A pilot hole was prepared in advance using the same method in all samples. Type A and type B pedicle screws were directly inserted into vertebrae in Groups A and B, respectively, and then different volumes of PMMA (0, 1.0, 1.5, and 2.0 mL) were injected through the screws and into vertebrae in Subgroups 0, 1, 2, and 3. The pilot holes were filled with different volumes of PMMA (0, 1.0, 1.5, and 2.0 mL), and then the screws were inserted in Groups C0, C1, C2, and C3. Screw position and distribution of PMMA were evaluated radiographically, and axial pullout tests were performed to measure maximum axial pullout strength (Fmax). RESULTS: Polymethylmethacrylate surrounded the anterior one-third of screws in the vertebral body in Groups A1, A2, and A3; the middle one-third of screws in the junction area of the vertebral body and the pedicle in Groups B1, B2, and B3; and the full length of screws evenly in both the vertebral body and the pedicle in Groups C1, C2, and C3. There was no malpositioning of screws or leakage of PMMA in any sample. Two-way analysis of variance revealed that two factors-distribution and volume of PMMA-significantly influenced Fmax (p<.05) but that they were not significantly correlated (p=.088). Fmax values in groups using augmentation with PMMA values significantly improved compared with those in groups without PMMA (p<.05). CONCLUSIONS: Polymethylmethacrylate can significantly enhance the stability of different injectable pedicle screws in osteoporotic lumbar vertebrae, and screw stability is significantly correlated with the distribution pattern and the injected volume of PMMA. The closer the PMMA to the pedicle and the greater the quantity of injected PMMA, the greater is the pedicle screw stability. Injection of 2.0 mL of PMMA through screws with four lateral 180 degrees holes or of 1.0 mL of PMMA through screws with six lateral 180 degrees holes increases the stability of pedicle screws. PMID- 29567518 TI - Three new platinum complexes containing fluoroquinolones and DMSO: Cytotoxicity and evaluation against drug-resistant tuberculosis. AB - This work describes the synthesis, characterization and biological evaluation of three platinum complexes of the type [Pt(DMSO)(L)Cl]Cl, in which L represents a fluoroquinolone, namely, ciprofloxacin (cpl), ofloxacin (ofl), or sparfloxacin (spf). The new complexes were characterized by elemental analysis, high resolution mass spectrometry (HRESIMS) and 1H, 13C and 195Pt NMR (nuclear magnetic resonance). The spectral data suggest that the fluoroquinolones act as bidentate ligands coordinated to Pt(II) through the nitrogen atoms of the piperazine ring. Microbiological assays against wild type Mycobacterium tuberculosis (ATCC 27294) showed that all complexes have been very potent, exhibiting antitubercular potency at concentrations <2 MUM, although none of the complexes presented higher potency than established anti-TB drugs. As to the resistant strains, the complex with sparfloxacin, [Pt(DMSO)(spf)Cl]Cl exhibited the best potential against most Mycobacterium tuberculosis clinical isolates. The cytotoxicity of these compounds was also evaluated in three breast cell lines: MCF-10 (a healthy cell), MCF-7 (a hormone responsive cancer cell) and MDA-MB-231 (triple negative breast cancer cell). In both tumor cell lines, [Pt(DMSO)(spf)Cl]Cl was more active and more selective than cisplatin. Flow cytometry analysis revealed that [Pt(DMSO)(spf)Cl]Cl induced late apoptotic cell death in MDA-MB-231 cells. PMID- 29567519 TI - Modification of the screw hole structures to improve the fatigue strength of locking plates. AB - BACKGROUND: The fatigue fracture of locking plates can substantially threaten fracture treatment results. In the present study, three measures for modifying the screw hole structures of plates were implemented to improve their fatigue strength. MATERIALS: Custom-made identical titanium locking plates, except the screw hole configurations, were tested using four-point bending load. The three measures were partial removal of screw threads on the tension side of the plates, reduction of screw hole size, and modification of the thread radii. There were six types of plates: control (Type I), half of the threads removed (Type II) or one-third of the threads (Type III), smaller screw holes (Type IV), and increase of the thread root radii (Type V) or crest radii (Type VI). FINDINGS: Compared with the control, Types II and III significantly improved the fatigue strength (14.5 and 10.1 times, respectively). Decreasing the size of the screw hole (Type IV) also yielded a higher fatigue strength (17.6%). Type VI significantly improved the fatigue strength (9.8 times). However, Type V decreased the fatigue strength (14%). For cyclic stiffness, Type IV was significantly higher than other types statistically. Failure analyses showed typical fatigue fracture in all plates and the cracks were always initiated at the thread crest. INTERPRETATIONS: The fatigue strength of titanium locking plates can be significantly improved by structural changes in the screw holes. Removing the threads of the plates and increasing the crest radii of the threads were more effective measures than decreasing the size of the screw holes. PMID- 29567520 TI - Removal of binary Cr(VI) and Cd(II) from the catholyte of MFCs and determining their fate in EAB using fluorescence probes. AB - Electrochemically active bacteria (EAB) on the cathodes of microbial fuel cells (MFCs) can remove metals from the catholyte, but the fate of metals in the cells has not been examined in the presence of multiple metals. To study the relative uptake and fate of Cr(VI) and Cd(II) in cells, fluorescence probes were used to determine the amount and location of these metals in four different EAB on the biocathodes of MFCs. When both metals were present, less Cr(VI) was removed but Cd(II) uptake was not appreciably affected. As a consequence, the imaging of Cr(III) ions was lower than that using individual fluorescence probes for single Cr(III) ions in each EAB, compared to negligible changes in images for Cd(II) ions in the presence of either both Cr(VI) and Cd(II) or Cd(II) alone. The concentration of Cr(III) ions in the cells consistently increased over time, while that of Cd(II) ions decreased following an initial increase. Cr or Cd uptake could not be detected using a scanning electron microscope coupled with an energy dispersive spectrometer, reflecting the high sensitivities of the fluorescence probes to these metals. More chromium was found in the cytoplasm while cadmium preferentially accumulated in the cell envelope. These results demonstrate that the fate of chromium and cadmium in EAB was different when both metals were present, compared to controls containing a single metal. These results provide direct and visible results on the fate of the metals in the EAB when these metals are co-present in the catholyte of MFCs. PMID- 29567521 TI - Changes in the structural features of osteoarthritis in a year of weight loss. AB - OBJECTIVE: In patients undergoing bariatric surgery or medical management for obesity, we assessed whether those experiencing substantial weight loss had changes in innervated knee structures or in cartilage. METHODS: Severely obese patients (body mass index (BMI) >=35) with knee pain on most days were seen before bariatric surgery or medical weight management and at 1-year follow-up. Examinations included 3T MRI acquired at both time points for semi-quantitative scoring of bone marrow lesions (BML), synovitis, cartilage damage, and for quantitative measurement of cartilage thickness. Association of >=20% vs <20% weight loss with change in semi-quantitative scores was evaluated using linear mixed-effects models, and that with cartilage thickness change used non parametric and parametric methods. Sensitivity analyses tested different thresholds for weight loss, weight loss as a continuous measure, examined those with and without bariatric surgery, and with worse osteoarthritis (OA). RESULTS: 75 subjects (median age 49 years, 92% women) were included. At baseline, 61 subjects (81%) had Kellgren and Lawrence (KL) grade >0, and 16 (21%) had KL grade >=3; 69 (92%) had cartilage damage. For BML, synovitis, and cartilage damage, the majority of knees had change in semi-quantitative scores of 0, and there was no difference between those with and without >=20% weight loss. Similarly, in terms of cartilage thickness loss, in 14 of 16 sub-regions thickness loss was not associated with weight loss. Sensitivity analyses showed similar findings. CONCLUSION: In middle-aged persons with mostly mild radiographic OA, structural features changed little over a year and weight loss was not associated with effects on structural changes.

PMID- 29567523 TI - Surface speciation of phosphate on goethite as seen by InfraRed Surface Titrations (IRST). AB - Phosphate adsorption at the metal oxide-water interface has been intensely studied, and the system phosphate-goethite in aqueous media is normally used as a model system with abundant information regarding adsorption-desorption under very different conditions. In spite of this, there is still discussion on whether the main inner-sphere surface complexes that phosphate forms on goethite are monodentate or bidentate. A new spectroscopic technique, InfraRed Surface Titration (IRST), is presented here and used to systematically explore the surface speciation of phosphate on goethite in the pH range 4.5-9.5 at different surface coverages. IRST enabled to construct distribution curves of surface species and distribution curves of dissolved phosphate species. In combination with the CD-MUSIC surface complexation model it was possible to conclude that surface complexes are monodentate. Very accurate distribution curves were obtained, showing a crossing point at pH5.5 at a surface coverage of 2.0MUmolm-2, with a mononuclear monoprotonated species predominating at pH>5.5 and a mononuclear diprotonated species prevailing at pH<5.5. On the contrary, at the low surface coverage of 0.7MUmolm-2 there is no crossing point, with the mononuclear monoprotonated species prevailing at all pH. IRST can become a powerful technique to investigate structure, properties and reactions of any IR active surface complex at the solid-water interface. PMID- 29567524 TI - Association of depression with body mass index classification, metabolic disease, and lifestyle: A web-based survey involving 11,876 Japanese people. AB - Body mass index (BMI) and lifestyle-related physical illnesses have been implicated in the pathology of depression. We aimed to investigate the association of depression wih BMI classification (i.e., underweight, normal, overweight, and obese), metabolic disease, and lifestyle using a web-based survey in a large cohort. Participants were 1000 individuals who have had depression (mean age: 41.4 +/- 12.3 years, 501 men) and 10,876 population-based controls (45.1 +/- 13.6 years, 5691 men). The six-item Kessler scale (K6) test was used as a psychological distress scale. Compared to in the controls, obesity and hyperlipidemia were more common and frequency of a snack or night meal consumption was higher, whereas frequencies of breakfast consumption and vigorous and moderate physical activities were lower in the patients. K6 test scores were higher for underweight or obese people compared to normal or overweight people. A logistic regression analysis showed that the K6 test cut-off score was positively associated with being underweight, hyperlipidemia, and the frequency of a snack or night meal consumption, whereas it was negatively associated with the frequency of breakfast consumption in the patients. Logistic regression analyses showed that self-reported depression was positively associated with metabolic diseases and the frequency of a snack or night meal consumption, whereas it was negatively associated with the frequency of breakfast consumption. The observed associations of depression with BMI classification, metabolic disease, and lifestyle suggest that lifestyle and related physical conditions are involved in at least a portion of depressive disorders. PMID- 29567525 TI - Perceived stigma and associated factors among children and adolescents with epilepsy in south western Uganda: A cross sectional study. AB - PURPOSE: To determine the prevalence of perceived stigma and its associated factors among children and adolescents with epilepsy in southwestern Uganda. METHODS: We conducted a cross sectional study at a large referral hospital and a small rural health facility in Mbarara district, southwestern Uganda. Participants were aged 6-18 years being managed for epilepsy for at least 3 months, with no medical emergencies. Perceived stigma was measured using the Kilifi Stigma Scale of Epilepsy. Data on associated factors were collected by a pre-piloted investigator designed questionnaire. Logistic regression was used to determine associated factors considering 5% statistical significance. RESULTS: Prevalence of high perceived stigma was 34% with higher levels among older children and adolescents. Children who had never attended school were more likely to report perceived stigma (62%). Factors associated with this stigma included having epilepsy related injuries or deformities (p = 0.022), other chronic illnesses (p = 0.009) and a longer duration of antiepileptic drug use (p = 0.004). CONCLUSIONS: Perceived stigma of epilepsy remains a major public health problem among children and adolescents and it is highly associated with preventable or modifiable factors. Therefore, there is need to design interventions that can address these factors in order to reduce the stigma and its potential future complications such as educational inequalities. PMID- 29567526 TI - Effect of modifications in mineralized collagen fibril and extra-fibrillar matrix material properties on submicroscale mechanical behavior of cortical bone. AB - A key length scale of interest in assessing the fracture resistance of bone is the submicroscale which is composed of mineralized collagen fibrils (MCF) and extra-fibrillar matrix (EFM). Although the processes through which the submicroscale constituents of bone contribute to the fracture resistance in bone have been identified, the extent of the modifications in submicroscale mechanical response due to the changes in individual properties of MCFs and EFM has not been determined. As a result, this study aims to quantify the influence of individual MCF and EFM material property modifications on the mechanical behavior (elastic modulus, ultimate strength, and resistance to failure) of bone at the submicroscale using a novel finite element modeling approach that incorporate 3D networks of MCFs with three different orientations as well as explicit representation of EFM. The models were evaluated under tensile loading in transverse (representing MCF separation) and longitudinal (representing MCF rupture) directions. The results showed that the apparent elastic modulus at the submicroscale under both loading directions for all orientations was only affected by the change in the elastic modulus of MCFs. MCF separation and rupture strengths were mainly dependent on the ultimate strength of EFM and MCFs, respectively, with minimal influence of other material properties. The extent of damage during MCF separation increased with increasing ultimate strength of EFM and decreased with increasing fracture energy of EFM with minimal contribution from elastic modulus of MCFs. For MCF rupture, there was an almost one-to-one linear relationship between the percent change in fracture energy of MCFs and the percent change in the apparent submicroscale fracture energy. The ultimate strength and elastic modulus of MCFs had moderate to limited influence on the MCF rupture fracture energy. The results of this study quantified the extent of changes that may be seen in the energy dissipation processes during MCF rupture and separation relative to the changes in the individual constituents of the tissue. This new knowledge significantly contributes to improving the understanding of how the material property alterations at the submicroscale that can occur due to diseases, age-related changes, and treatments affect the fracture processes at larger length scales.

AB - Poor surface wettability and relative high friction coefficients of pristine polyetheretherketone (PEEK) have limited its application in orthopedic implants. In this study, inspired by the structure of natural articular cartilage, we presented a novel method to fabricate a "soft-on-hard" structure on the surface of pristine PEEK specimens, which combined a soft polyvinyl alcohol (PVA) hydrogel layer and a three-dimensional porous layer with PEEK substrates. A variety of analytical methods were used to evaluate their properties, our results demonstrated that the hydrogel layer could be seamlessly connected with substrate, and the hydrogel-covered PEEK owned a highly hydrophilic surface, a very low water contact angle of 7 degrees could be obtained. The friction coefficients of untreated and hydrogel-covered PEEK surfaces were measured using a tribometer under water lubrication, due to the presence of the top hydrogel layer and the hard substrate could provide excellent aqueous lubrication and bearing capacity, respectively, the friction coefficient could be reduced from 0.292 to 0.021. In addition, the porous layer under PVA hydrogel layer could work as gel reservoirs, the reserved hydrogel would be released after the surface layer was sheared off, and a regenerable lubrication status was obtained. This work provides a new route for the design of improving the surface wettability and tribological properties of PEEK. PMID- 29567528 TI - Nano-scale mechanical behavior of pre-crystallized CAD/CAM zirconia-reinforced lithium silicate glass ceramic. AB - This paper reports on the mechanical behavior of pre-crystallized CAD/CAM zirconia-reinforced lithium silicate glass ceramic (ZLS) using nanoindentation with a Berkovich diamond tip and in situ scanning probe microscopy (SPM). The indentation contact hardness, the elastic modulus, and the elasticity and plasticity of the material were determined using the Oliver-Pharr method, the Sakai model and the Meyer's law at peak loads of 2.5-10 mN and a loading rate of 0.5 mN/s. The load-displacement curves at all applied loads indicate that ZLS deformed plastically without fracture. The discrete discontinuities in the load displacement curves might have arisen from the shear plane activation for plastic deformation. The measured hardness and elastic modulus were load-independent (ANOVA, p > 0.05), in ranges of 8.17 +/- 1.23 GPa to 9.86 +/- 1.24 GPa and 98.55 +/- 7.38 GPa to 105.78 +/- 9.98 GPa, respectively. The resistance to plasticity of ZLS significantly showed a second-order polynomial load relationship or a power law load dependency. Meanwhile, both the elastic and plastic displacements also significantly revealed power law load dependencies. However, the elastic and plastic deformation components were load-independent. Increased indentation loads resulted in significant decreases in the normalized elastic strain energy (p < 0.05) accompanied by significant increases in the normalized indentation absorbed energy (p < 0.05). The equivalent elasticity and plasticity of ZLS during indentation occurred at 7.5 mN. The outcomes of this study provide insights into fabrication and mechanical functions of ZLS restorations, particularly facilitating abrasive machining in dental CAD/CAM processing in the ductile regime. PMID- 29567529 TI - Characterization of the anisotropic mechanical behavior of human abdominal wall connective tissues. AB - Abdominal wall sheathing tissues are commonly involved in hernia formation. However, there is very limited work studying mechanics of all tissues from the same donor which prevents a complete understanding of the abdominal wall behavior and the differences in these tissues. The aim of this study was to investigate the differences between the mechanical properties of the linea alba and the anterior and posterior rectus sheaths from a macroscopic point of view. Eight full-thickness human anterior abdominal walls of both genders were collected and longitudinal and transverse samples were harvested from the three sheathing connective tissues. The total of 398 uniaxial tensile tests was conducted and the mechanical characteristics of the behavior (tangent rigidities for small and large deformations) were determined. Statistical comparisons highlighted heterogeneity and non-linearity in behavior of the three tissues under both small and large deformations. High anisotropy was observed under small and large deformations with higher stress in the transverse direction. Variabilities in the mechanical properties of the linea alba according to the gender and location were also identified. Finally, data dispersion correlated with microstructure revealed that macroscopic characterization is not sufficient to fully describe behavior. Microstructure consideration is needed. These results provide a better understanding of the mechanical behavior of the abdominal wall sheathing tissues as well as the directions for microstructure-based constitutive model. PMID- 29567530 TI - A combined strategy to enhance the properties of Zn by laser rapid solidification and laser alloying. AB - The orthopedic application of Zn is limited owing to the poor strength and low plasticity. In this study, a novel strategy by combining rapid solidification obtained by selective laser melting (SLM) and alloying with Mg was proposed to improve the mechanical properties of Zn. The microstructures, mechanical properties, as well as in vitro cytocompatibility of SLM processed Zn-xMg (x = 0 4 wt%) were studied systematically. Results shown that SLM processed Zn-xMg alloys consisted of fine equiaxed alpha-Zn grains with homogeneously precipitated Mg2Zn11 along grain boundaries. More importantly, the grains size of alpha-Zn was decreased from 104.4 +/- 30.4 um to 4.9 +/- 1.4 um with Mg increasing. And Mg mainly dissolved in alpha-Zn developing into supersaturated solid solution due to rapid solidification effect. As a consequence, the ultimate tensile strength and elongation were enhanced by 361% and 423%, respectively, with Mg containing up to 3 wt%. Meanwhile, alloying with Mg enhanced the corrosion resistance of Zn, with the degradation rate decreasing from 0.18 +/- 0.03 mm year-1 to 0.10 +/- 0.04 mm year-1. Furthermore, SLM processed Zn-xMg exhibited good biocompatibility. This research suggested that SLM processed Zn-3Mg alloy was a potential biomaterial for orthopedic applications. PMID- 29567531 TI - Nondegradable magnetic poly (carbonate urethane) microspheres with good shape memory as a proposed material for vascular embolization. AB - In this study, nondegradable poly (carbonate urethane) (PCU) and poly (carbonate urethane) incorporated variable Fe3O4 content microspheres (PCU/Fe3O4) were synthesized using pre-polymerization and suspension polymerization. Synthesis was confirmed through Fourier transform infrared spectroscopy (FTIR). The effect of Fe3O4 incorporation was investigated on crystalline, thermal, shape memory and degradation properties by X-Ray diffraction (XRD), Differential scanning calorimetery (DSC), compression test and degradation in vitro, respectively. Otherwise, the assessment of magnetic characteristics by vibrational sample magnetometry (VSM) disclosed superparamagnetic behavior. The tunable superparamagnetic behavior depends on the amount of magnetic particles incorporated within the networks. The biological study results of as-synthesized polymers from the platelet adhesion test and the cell proliferation inhibition test indicated they were biocompatible in vitro. Fe3O4 incorporation was conductive to reducing platelet adhesion in blood contacting test and promotion of rat vascular smooth muscle cell proliferation and growth. These nondegradable, superparamagnetic, biocompatible polymers, combined with their good shape memory properties may allow for their future exploitation in the biomedical field, such as, in cardiovascular implants, targeted tumor treatment, tissue engineering and artificial organ's engineering. PMID- 29567532 TI - Adaptive Bayesian inference system for recognition of walking activities and prediction of gait events using wearable sensors. AB - In this paper, a novel approach for recognition of walking activities and gait events with wearable sensors is presented. This approach, called adaptive Bayesian inference system (BasIS), uses a probabilistic formulation with a sequential analysis method, for recognition of walking activities performed by participants. Recognition of gait events, needed to identify the state of the human body during the walking activity, is also provided by the proposed method. In addition, the BasIS system includes an adaptive action-perception method for the prediction of gait events. The adaptive approach uses the knowledge gained from decisions made over time by the inference system. The action-perception method allows the BasIS system to autonomously adapt its performance, based on the evaluation of its own predictions and decisions made over time. The proposed approach is implemented in a layered architecture and validated with the recognition of three walking activities:level-ground, ramp ascent and ramp descent. The validation process employs real data from three inertial measurements units attached to the thigh, shanks and foot of participants while performing walking activities. The experiments show that mean decision times of 240 ms and 40 ms are needed to achieve mean accuracies of 99.87% and 99.82% for recognition of walking activities and gait events, respectively. The validation experiments also show that the performance, in accuracy and speed, is not significantly affected when noise is added to sensor measurements. These results show that the proposed adaptive recognition system is accurate, fast and robust to sensor noise, but also capable to adapt its own performance over time. Overall, the adaptive BasIS system demonstrates to be a robust and suitable computational approach for the intelligent recognition of activities of daily living using wearable sensors. PMID- 29567533 TI - High salt diet induces metabolic alterations in multiple biological processes of Dahl salt-sensitive rats. AB - High salt induced renal disease is a condition resulting from the interactions of genetic and dietary factors causing multiple complications. To understand the metabolic alterations associated with renal disease, we comprehensively analyzed the metabonomic changes induced by high salt intake in Dahl salt-sensitive (SS) rats using GC-MS technology and biochemical analyses. Physiological features, serum chemistry, and histopathological data were obtained as complementary information. Our results showed that high salt (HS) intake for 16 weeks caused significant metabolic alterations in both the renal medulla and cortex involving a variety pathways involved in the metabolism of organic acids, amino acids, fatty acids, and purines. In addition, HS enhanced glycolysis (hexokinase, phosphofructokinase and pyruvate kinase) and amino acid metabolism and suppressed the TCA (citrate synthase and aconitase) cycle. Finally, HS intake caused up regulation of the pentose phosphate pathway (glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase), the ratio of NADPH/NADP+, NADPH oxidase activity and ROS production, suggesting that increased oxidative stress was associated with an altered PPP pathway. The metabolic pathways identified may serve as potential targets for the treatment of renal damage. Our findings provide comprehensive biochemical details about the metabolic responses to a high salt diet, which may contribute to the understanding of renal disease and salt induced hypertension in SS rats.

AB - We evaluate the effects of home visiting targeted towards disadvantaged first time mothers on maternal and child health outcomes. Our analysis exploits a randomized controlled trial and combines rich longitudinal survey data with unique administrative health data. In a context in which the target group has comprehensive health care access, we find no effects of home visiting on most types of health utilization, health behaviors, and physical health measures. However, the intervention has a positive effect on some maternal mental health outcomes, reducing depression reported in the survey data by eleven percentage points and prescription of psycholeptics recorded in the administrative data by seven percentage points. PMID- 29567535 TI - Nanobodies targeting cortactin proline rich, helical and actin binding regions downregulate invadopodium formation and matrix degradation in SCC-61 cancer cells. AB - Cortactin is a multidomain actin binding protein that activates Arp2/3 mediated branched actin polymerization. This is essential for the formation of protrusive structures during cancer cell invasion. Invadopodia are cancer cell-specific membrane protrusions, specialized at extracellular matrix degradation and essential for invasion and tumor metastasis. Given the unequivocal role of cortactin at every stage of invadopodium formation, it is considered an invadopodium marker and potential drug target. We used cortactin nanobodies to examine the role of cortactin domain-specific function at endogenous protein level. Two cortactin nanobodies target the central region of cortactin with high specificity. One nanobody interacts with the actin binding repeats whereas the other targets the proline rich region and was found to reduce EGF-induced cortactin phosphorylation. After intracellular expression as an intrabody, they are both capable of tracing their target in the complex environment of the cytoplasm, and disturb cortactin functions during invadopodia formation and extracellular matrix degradation. These data illustrate the use of nanobodies as a research tool to dissect the role of cortactin in cancer cell motility. This information can contribute to the development of novel therapeutics for tumor cell migration and metastasis. PMID- 29567536 TI - Role of lncRNAs in the cancer development and progression and their regulation by various phytochemicals. AB - Long non coding RNAs (lncRNAs) are involved in modulating the expression of other non-coding RNAs (ncRNA), such as microRNAs, or target proteins through the epigenetic, transcriptional, or post-transcriptional regulations. Genomic mutations in cancer reside inside regions that do not code for proteins and these regions are often transcribed into long non coding RNAs (lncRNAs). Emerging evidences have revealed an intense involvement of lncRNAs in the cancer development and progression. Recently, emerging evidences have depicted that the phytochemicals interact with lncRNAs to modulate their activities. Such findings are highly important for the identification of therapeutic strategies against diseases that are particularly associated with an aberrant lncRNA signaling. This review aims at deciphering the role of lncRNAs in the cancer development and progression, and their regulation by various phytochemicals. PMID- 29567537 TI - Trans-anethole prevents hypertension induced by chronic exposure to both restraint stress and nicotine in rats. AB - Chronic stress and smoking are major risk factors for hypertension, with stress also being a factor predisposing to smoking. Methods are needed to prevent and/or reduce hypertension induced by chronic exposure to both stress and nicotine. This study investigated whether trans-anethole would prevent hypertension induced by chronic exposure to both restraint stress and nicotine in rats. Rats received nicotine intraperitoneally for 21 days following restraint stress (2 h/day) and trans-anethole (62, 125, and 250 mg/kg) on days 4, 8, 12, 16 and 20. To confirm the preventive effects of trans-anethole, blood pressure and vascular tone were measured on the last day of the experiment, and compared with the results of nifedipine and aerobic exercise. The ability of trans-anethole, at doses of 125 mg/kg and 250 mg/kg, to prevent hypertension was comparable to that of aerobic exercise and nifedipine. Furthermore, nifedipine combined with aerobic exercise and trans-anethole reduced both blood pressure and vascular tone. These findings are the first to show that trans-anethole can prevent hypertension, suggesting that trans-anethole may be useful as a prophylactic antihypertensive agent.

Recently some studies have explained premature ovarian insufficiency (POI). The causes of it are unknown although various types of study have been done. The most common causes such as genetic and autoimmune conditions can have a role in POF and can lead to infertility. Some characterization of POF are hypo-oestrogenism (estrogen deficiency), increased gonadotropin level and most importantly amenorrhea. The main purpose of this review is to describe the cause and treatment of POF, especially stem cell therapy proposed in previous studies. Stem cells have self-renewal and regeneration potential, hence they can be very effective in the treatment of ovarian failure and consequently infertility. There are several kinds of stem cells such as, mesenchymal stem cells (MSCs), stem cells from extra-embryonic tissues, induced pluripotent stem cells (iPSCs), and ovarian stem cells that are used in POF stem cell therapy as observed in previous studies. This article reviews the latest studies on POF to summarize current understanding and future directions.

AB - This work aims to study the roles and mechanisms of metformin in glioma cells stemness and epithelial-mesenchymal transition. Here, we found that metformin suppressed glioma cells spheroid formation and size, inhibited the expression of glioma stemness-related marker, CD133. Additionally, Metformin attenuated TGF beta-induced epithelial-mesenchymal transition in glioma cells. Mechanistically, metformin inhibited the nuclear abundance of YAP, a key effector of Hippo pathway, subsequently leading to its cytoplasmic retention, and thus reduced YAP transcriptional modulating activity. Importantly, overexpression of a mutant form of YAP (YAP-5SA) attenuated the inhibition of metformin on glioma cells stemness and epithelial-mesenchymal transition. Thus, metformin inhibits glioma cells stemness and epithelial-mesenchymal transition via regulating YAP activity. PMID- 29567540 TI - Silencing ZAP70 prevents HSP65-induced reverse cholesterol transport and NF kappaB activation in T cells. AB - T cell activation by antigens binding to the T cell receptor (TCR) must be properly regulated to ensure normal T cell development. The zeta chain-associated 70-kDa protein (ZAP70) is sequentially activated in response to TCR engagement and serves as a critical component of the TCR signaling pathway, which is essential for T cell activation. However, some roles of ZAP70 have not been fully elucidated. In the present study, we analyzed the effects of ZAP70 on the cholesterol efflux rate, nuclear factor kappaB (NF-kappaB) activation and cell proliferation in T cells. Our study showed that silencing ZAP70 increased the cholesterol efflux rate in T cells. We also found that silencing ZAP enhanced the expression of ATP-binding cassette transporter A1 (ABCA1), ATP-binding cassette transporter G1 (ABCG1), scavenger receptor-BI (SR-BI) peroxisome proliferator activated receptor-gamma (PPAR-gamma) and liver X receptor-alpha (LXR-alpha). In contrast, the phosphorylation of ZAP70 by HSP65 decreased the cholesterol efflux rate and the expression of five cholesterol transport proteins in T cells. The phosphorylation of ZAP70 activated the downstream NF-kappaB signaling pathway, which is involved in both T cell growth and function. Furthermore, silencing ZAP70 inhibited T cell proliferation. These results indicate a crucial and unexpected role for ZAP70 in the physiological activities of T cells, suggesting that inhibition of ZAP70 is beneficial for anti-atherosclerosis. PMID- 29567541 TI - Epiisopiloturine, an imidazole alkaloid, reverses inflammation and lipid peroxidation parameters in the Crohn disease model induced by trinitrobenzenosulfonic acid in Wistar rats. AB - Epiisopiloturine (EPI) is an important imidazole alkaloid because of its pharmacological properties. The aim of this study was to investigate the effects of epiisopiloturine on inflammatory parameters of the colonic mucosa in a rat model of Crohn's disease (CD). For this, we induced colitis using trinitrobenzenosulfonic acid and determined myeloperoxidase (MPO), interleukin 1 beta (IL-1beta), glutathione (GSH), and malondialdehyde (MDA) levels in the intestinal mucosa. The location and expression of the inflammatory markers in the colon were investigated by immunohistochemistry for NO synthase induced (iNOS), interleukin 1 beta (IL-1beta), and cyclooxygenase-2 (COX-2) and western blotting (iNOS and COX-2), respectively. Compared with TNBS alone, epiisopiloturine at 1 mg/kg reduced the macroscopic and microscopic scores, wet weight of the colon, and neutrophilic infiltration and expression of the pro-inflammatory cytokine IL 1beta. Epiisopiloturine at 1 mg/kg maintained or restored GSH levels and simultaneously decreased MDA levels. Animals treated with epiisopiloturine exhibited reduced immunostaining for IL-1beta, iNOS, and COX-2 and reduced cell count per field. Epiisopiloturine reduced the expression of COX-2 and iNOS in the colon. Based on these findings, we conclude that epiisopiloturine at 1 mg/kg may be an important pharmacological tool against intestinal inflammatory diseases due to its inhibitory action on key enzymes and products involved in inflammation. PMID- 29567542 TI - MicroRNA-132 and microRNA-212 mediate doxorubicin resistance by down-regulating the PTEN-AKT/NF-kappaB signaling pathway in breast cancer. AB - Breast cancer is a serious health problem worldwide. Acquisition of multi-drug resistance (MDR) during the treatment of breast cancer is still considered a major clinical obstacle. Despite the biological functions of miRNAs becoming increasingly apparent, the function of miRNAs in regulating drug resistance of breast cancer remains under investigation. Quantitative real-time PCR (qRT-PCR) was used to quantify the expression of miR-132/-212 (miR-132 and miR-212) in doxorubicin (DOX)-resistant and -sensitive breast cancer tumors and cells. The function of miR-132/-212 in drug resistance was investigated in vitro (MTT assay, TUNEL assay, fluorescence, immunohistochemistry, luciferase reporter assay, Western blotting). We found that miR-132/-212 were commonly overexpressed in DOX resistant breast cancer tumors and cells. Silenced miR-132/-212 expression induced DOX accumulation in MCF-7/ADR cells, while overexpression of miR-132/-212 led to breast cancer resistance protein (BCRP)-based DOX efflux in MCF-7 cells. Further study showed that up-regulation of miR-132/-212 in MCF-7/ADR cells suppressed the expression of PTEN, a target gene of miR-132/-212, which activated AKT phosphorylation and the NF-kappaB pathway and led to increased BCRP expression. Down-regulation of miR-132/-212 sensitized MCF-7/ADR cells to DOX. Mechanistic investigations suggested that miR-132/-212 enhancement was a result of NF-kappaB-mediated transactivation of the pri-miR-132/-212 gene. Taken together, our findings are among the first to demonstrate a novel aspect of the miR-132/-212-PTEN-AKT/NF-kappaB-BCRP pathway in the generation of breast cancer resistance and provides a potential method to reverse drug resistance. PMID- 29567543 TI - Astragalus polysaccharide protects hypoxia-induced injury by up-regulation of miR 138 in rat neural stem cells. AB - Astragalus polysaccharide (APS) is the main active ingredient of astragalus and exhibits various pharmacological effects. This study aimed to investigate the effect of APS on hypoxia-induced injury in neural stem cells (NSCs). The NSCs derived from the hippocampus of rat were subjected to hypoxia incubator to establish a hypoxia model. NSCs were pretreated with APS before hypoxia injury to investigate the effect of APS. The expression of miR-138 was inhibited by transfection with miR-138 inhibitor and the miR-138 level was measured by qRT PCR. Cell viability and apoptotic cell rates were respectively assessed by CCK-8 assay and flow cytometry assay. Western blot was performed to determine the expression of apoptosis-, JNK pathway- and p38MAPK pathway-related factors. Hypoxia exposure caused the reduction of cell viability and induction of cell apoptosis of NSCs. However, APS pretreatment attenuated the cell injury induced by hypoxia, as evidenced by increased cell viability, reduced apoptotic cells, inhibited expression of pro-apoptotic factors and enhanced expression of anti apoptotic factor. Interestingly, higher miR-138 expression was observed in the hypoxia-injured NSCs compared with normoxia, and miR-138 expression was further up-regulated by APS pretreatment. Furthermore, miR-138 inhibitor blocked the protective effect of APS on hypoxia-injured NSCs. In addition, we found that APS inhibited the JNK and p38MAPK pathways through miR-138. In conclusion, this study demonstrated a protective effect of APS on hypoxia-induced NSC injury. The regulatory mechanism might be mediated by up-regulation of miR-138 and inhibition of the JNK and p38MAPK pathways. PMID- 29567544 TI - Estimating age and synthesising growth in children and adolescents using 3D facial prototypes. AB - 3D facial images are becoming increasingly common. They provide more information about facial form than their 2D counterparts and will be useful in future forensic applications. These include age estimation and predicting changes in appearance of missing persons (synthetic growth). We present a framework for both age estimation and synthetic growth of children and adolescents from 3D photographs. Age estimation accuracy was substantially better than for existing approaches (mean absolute error=1.19 years). Our synthetically 'grown' images were compared to actual longitudinal images of the same cases. On average 75% of the head overall and 85% of the face were predicted correctly to within three millimetres. We find that our approach is most suitable for ageing children from late childhood into adolescence. The work can be improved in the future by modelling skin colouring and taking account of other factors that influence face shape such as BMI. PMID- 29567545 TI - A commentary on the effects of methamphetamine and the status of methamphetamine abuse among youths in South Korea, Japan, and China. AB - Methamphetamine (MA) abuse continues in East Asia and shows an increasing trend among youths in South Korea, Japan, and China. Although the negative effects of MA abuse on youth are considered as significant problems, few studies have been conducted on the topic in these countries. This paper focuses on the effects of MA on the human body and current MA abuse among youths in South Korea, Japan, and China. To investigate the negative effects of MA on the human body, we searched the keywords "MA," "human," and "effect" for studies published from 2013 to 2017. MA activates the neurotransmitter system and the central nervous system, and when used at high dosage or for long term, MA can cause severe neurotoxicity and cardiovascular problems. Online networks contribute to MA abuse by sharing methods for preparing synthetic MA. Despite efforts to reduce MA abuse, social crimes associated with its abuse continue and numbers of illegal MA users are increasing steadily in Korea, Japan, and China. In young users, diverse factors associated with drug addiction, such as curiosity and peer effect, lead to MA abuse and its attendant personal and social problems. PMID- 29567546 TI - Body image related negative interpretation bias in anorexia nervosa. AB - A distorted body image and pronounced body dissatisfaction are hallmarks of anorexia nervosa (AN) that typically result in dietary restraint and compensatory behaviours. Cognitive biases such as negative interpretation bias are considered key maintaining factors of these maladaptive cognitions and behaviours. However, little attention has been paid to empirical tests whether negative interpretation bias exists in AN and to what degree it is associated with symptom severity. Participants in the present study were 40 women with AN and 40 healthy women with no history of an eating disorder. Body-related negative interpretation bias (i.e., a tendency to interpret ambiguous information about the own body in a negative way) was measured by a Scrambled Sentences Task. Patients with AN showed a stronger body-related negative interpretation bias than healthy controls. Within both groups, negative interpretation bias correlated strongly and positively with AN symptom severity and these effects were not moderated by levels of depressive symptoms. The findings support the idea that biased interpretation of body-related information is associated with the specific psychopathology of AN. Targeted, computerised interventions (e.g. interpretation bias modification) may help to alter these dysfunctional cognitive schemas that lie at the heart of AN. PMID- 29567547 TI - Longitudinal relations among maternal depressive symptoms, maternal mind mindedness, and infant attachment behavior. AB - The relations among maternal depression risk, maternal mind-mindedness, and infants' attachment behavior were longitudinally examined in a community sample of mother-infant dyads. Maternal self-reported depression risk was measured at the infant ages of 6 weeks, 4 months, and 12 months. Maternal mind-mindedness, assessed from mothers' comments about infants' mental states (e.g., infants' thoughts, desires, or emotions), was measured during mother-infant interactions when infants were 4 months. Infants' attachment behavior was assessed at one year. Mothers' depression risk decreased over the infants' first year, with the sharpest decline between 6 weeks and 4 months. Mothers at risk for depression when infants were 6 weeks showed less appropriate mind-mindedness at 4 months. Mind-mindedness was not related to maternal depression risk at the infant age of 4 months or 12 months. Infants' degree of disorganized attachment behavior at one year was positively associated with maternal depression risk at 6 weeks and negatively associated with maternal appropriate mind-mindedness at 4 months. Mothers who are at risk for depression in their infants' early lives may be hampered in their capacity to respond appropriately to their infants' mental states. Infants with mothers who have difficulty responding appropriately to their mental states, as suggested by low appropriate mind-mindedness, may feel less known and recognized by their mothers, a key theme in the origins of disorganized attachment. PMID- 29567548 TI - Analysis of proteoglycan expression in human dental pulp. AB - : Proteoglycans are glycosylated proteins which have covalently attached highly anionic glycosaminoglycans. They can be located on the extracellular matrix, cell membrane or intracellular granules. To date, few studies have reported the presence of proteoglycans in human dental pulp. OBJECTIVE: The aim of this study was, therefore, to analyze the expression of lumican, versican and glypican proteoglycans in deciduous and permanent human dental pulp by real-time polymerase chain reaction (q-PCR) and immunofluorescence. DESIGN: Healthy human dental pulps were used: 13 from permanent teeth (group 1) and eight from deciduous teeth (group 2). Versican, lumican and glypican (glypican-1 to 6) gene expressions were quantitatively evaluated by real-time PCR technique, using the expression of the endogenous gene GAPDH as control. Pulp sections were submitted to immunostaining procedure with fluorescence labelling, the tissues being fixed and incubated with well-characterized monoclonal and polyclonal antibodies against proteoglycan epitopes, including anti-versican and anti-lumican. Comparisons among the groups of the quantitative scores for each proteoglycan were analyzed using the t-test and ANOVA (P < 0.05). RESULTS: The real-time PCR analysis showed expression of versican and lumican proteoglycans in the two groups, with significant predominance of lumican gene (P = 0.03). Considering the glypican genes, glypican-3 was the proteoglycan most significantly expressed in permanent pulps (P < 0.001), while glypican-2 was not expressed in this tissue. The immunofluorescence quantification exhibited no significant differences between lumican and versican among the pulps and groups. CONCLUSIONS: The lumican gene was more expressed than versican and glypican-3 was the isoform more expressed in permanent pulp compared to deciduous. PMID- 29567549 TI - An Aspergillus aculateus strain was capable of producing agriculturally useful nanoparticles via bioremediation of iron ore tailings. AB - Mining waste such as iron ore tailing is environmentally hazardous, encouraging researchers to develop effective bioremediation technologies. Among the microbial isolates collected from iron ore tailings, Aspergillus aculeatus (strain T6) showed good leaching efficiency and produced iron-containing nanoparticles under ambient conditions. This strain can convert iron ore tailing waste into agriculturally useful nanoparticles. Fourier-transform Infrared Spectroscopy (FT IR analysis) established the at the particles are protein coated, with energy dispersive X-ray Spectroscopy (EDX analysis) showing strong signals for iron. Transmission Electron Microscopy (TEM analysis) showed semi-quasi spherical particles having average size of 15 +/- 5 nm. These biosynthesized nanoparticles when tested for their efficacy on seed emergence activity of mungbean (Vigna radiata) seeds, and enhanced plant growth at 10 and 20 ppm. PMID- 29567550 TI - Redirecting fire-prone Mediterranean ecosystems toward more resilient and less flammable communities. AB - The extensive abandonment of agricultural lands in the Mediterranean basin has led to large landscapes being dominated by early-successional species, characterized by high flammability and an increasing fire risk. This fact promotes fire occurrence and places ecosystems in a state of arrested succession. In this work, we assessed the effectiveness of several restoration actions in redirecting these ecosystems toward more resilient communities dominated by resprouting species. These actions included the mechanical clearing of early successional species, the plantation of resprouting species, and the combination of both treatments. For 13 years, we assessed shifts in the successional trajectory and ecosystem flammability by changes in: species composition, species richness, ecosystem evenness, the natural colonization of resprouting species, total biomass and proportion of dead biomass. We observed that the plantation and clearing combination was a suitable strategy to promote resilience. Species richness increased as well as the presence of the resprouting species introduced by planting. The natural colonization of the resprouting species was also enhanced. These changes in the successional trajectory were accompanied by a possible reduction of fire risk by reducing dead fuel proportion. These findings are relevant for the management of Mediterranean basin areas, but also suggest new tools for redirecting systems in fire-prone areas worldwide. PMID- 29567551 TI - Combination of ground rice husk and polyvinyl alcohol fiber in cementitious composite. AB - In this study, ground rice husks (GRH) in combination with polyvinyl-alcohol (PVA) fiber were used to produce low-cost and high-quality hybrid cementitious composites. Different amounts of GRH (2.5, 5.0, 7.5 and 12.5% in weight of cement) were added to the concrete. The work presented in this paper provides an insight into the use of an agricultural waste as effective additive in cement based materials. The properties of resultant cementitious composites including density, water absorption, flexural behavior and compressive strength were investigated. The results have shown that incorporation of ground rice husk in combination with PVA fiber can be effective in improvement of the flexural properties of cementitious composite. The study explored the effectiveness of this type of agricultural waste as a beneficial material in fine aggregate concrete materials. PMID- 29567552 TI - Nitrogen-enriched carbon sheet for Methyl blue dye adsorption. AB - In this work, nitrogen-enriched carbon sheet (NECS) was successfully fabricated by using sodium gluconate as a carbon source via melamine assisted chemical blowing approach. The obtained material exhibits sheet-like morphology with ultra thin thickness and has a high specific surface area of 604 m2g-1 and high nitrogen contents of 11.2 wt%. The NECS showed an excellent adsorption performance towards the removal of anionic dye Methyl blue (a-Mb). The adsorption of a-Mb onto NECS better fitted the Langmuir isotherm model with the highest adsorption capacity of 847 mg g-1. Interestingly, the NECS showed a pH-sensitive behavior towards the adsorption efficiency of a-Mb dye in which the adsorption capacity abruptly increased from 34 to 701 mg g-1 when the pH of the solution was decreased from 10 to 2. Furthermore, the adsorbed materials can be easily regenerated without obvious efficiency loss over a five adsorption-desorption cycles. PMID- 29567553 TI - Arsenic and fluoride removal from contaminated drinking water with Haix-Fe-Zr and Haix-Zr resin beads. AB - The objective of the study was to carry-out batch tests to examine the effectiveness of Haix-Fe-Zr and Haix-Zr resin beads in the removal of As(III), As(V) and F- from groundwater with a similar geochemistry to a site where a community-based drinking water plant has been installed in West Bengal, India. The groundwater was spiked separately with ~200 MUg/L As(III) and As(V) and 5 mg/L F-. Haix-Zr resin beads were more effective than Haix-Fe-Zr resin beads in removing As(III) and As(V). Haix-Zr resin beads showed higher removal of As(V) compared to As(III). Haix-Zr resin beads removed As(V) below the WHO (10 MUg/L) drinking water standards at 8.79 MUg/L after 4 h of shaking, while As(III) was reduced to 7.72 MUg/L after 8 h of shaking. Haix-Fe-Zr resin beads were more effective in removing F- from the spiked groundwater compared to Haix-Zr resin beads. Concentrations of F- decreased from 6.27 mg/L to 1.26 mg/L, which is below the WHO drinking water standards (1.5 mg/L) for F-, after 15 min of shaking with Haix-Fe-Zr resin beads. After 20 min of shaking in groundwater treated with Haix Zr resin beads, F- concentrations decreased from 6.27 mg/L to 1.43 mg/L. In the removal of As(III), As(V), and F- from the groundwater, Haix-Fe-Zr and Haix-Zr resin beads fit the parabolic diffusion equation (PDE) suggesting that adsorption of these contaminants was consistent with inter-particle diffusion. PMID- 29567554 TI - Harnessing the bio-mineralization ability of urease producing Serratia marcescens and Enterobacter cloacae EMB19 for remediation of heavy metal cadmium (II). AB - In the present study, urease positive Serratia marcescens (NCIM2919) and Enterobacter cloacae EMB19 (MTCC10649) were individually evaluated for remediation of cadmium (II) using ureolysis-induced calcium carbonate precipitation. Both the cultures were observed to efficiently remove cadmium from the media through co-precipitation of Cd (II) and Ca (II). S. marcescens and E. cloacae EMB19, respectively showed 96 and 98% removal of initial 5.0 mg L-1 soluble Cd (II) from the urea and CaCl2 laden media at 96 h of incubation period. At higher Cd (II) concentrations of 10 and 15 mg L-1, cadmium removal efficiency was much higher in case of E. cloacae EMB19 compared to S. marcescens. In-vitro cadmium (II) remediation study using urease containing cell-free culture supernatant of S. marcescens and E. cloacae EMB19 showed respective 98 and 53% removal of initial 50 mg L-1 Cd (II) from the reaction mixtures in co-presence of Ca (II). While in sole presence of Cd (II), only 16 and 8% removal of Cd (II) were detected for S. marcescens and E. cloacae EMB19, respectively. The elemental analysis of the co-precipitated mineral products using Energy Dispersive X-ray spectroscopy (EDX) clearly showed the prevalence of Ca and Cd ions. The morphology Cd-Ca composites formed with respect to both the cultures were observed to be of different shape and size as revealed through Scanning Electron Microscopy (SEM). Entire study hence comes out with a sustainable bioremediation option which could be effectively used to tackle Cd (II) or other heavy metal pollution. PMID- 29567555 TI - Evaluating a novel tiered scarcity adjusted water budget and pricing structure using a holistic systems modelling approach. AB - Population growth, coupled with declining water availability and changes in climatic conditions underline the need for sustainable and responsive water management instruments. Supply augmentation and demand management are the two main strategies used by water utilities. Water demand management has long been acknowledged as a least-cost strategy to maintain water security. This can be achieved in a variety of ways, including: i) educating consumers to limit their water use; ii) imposing restrictions/penalties; iii) using smart and/or efficient technologies; and iv) pricing mechanisms. Changing water consumption behaviours through pricing or restrictions is challenging as it introduces more social and political issues into the already complex water resources management process. This paper employs a participatory systems modelling approach for: (1) evaluating various forms of a proposed tiered scarcity adjusted water budget and pricing structure, and (2) comparing scenario outcomes against the traditional restriction policy regime. System dynamics modelling was applied since it can explicitly account for the feedbacks, interdependencies, and non-linear relations that inherently characterise the water tariff (price)-demand-revenue system. A combination of empirical water use data, billing data and customer feedback on future projected water bills facilitated the assessment of the suitability and likelihood of the adoption of scarcity-driven tariff options for a medium-sized city within Queensland, Australia. Results showed that the tiered scarcity adjusted water budget and pricing structure presented was preferable to restrictions since it could maintain water security more equitably with the lowest overall long-run marginal cost. PMID- 29567556 TI - Natural organic matter residue as a low cost adsorbent for aluminum. AB - The contamination of aquatic and terrestrial environments by potentially toxic metals is highlighted by the possible impacts that their high availability can have on the environment. Thus, the development of alternative absorbents that can be used in the remediation of contaminated areas is of great environmental interest. Humin, one of the fractions of natural organic matter, is a promising alternative in studies on the retention of different metals that are environmentally toxic. In this study, the influence of the organic and inorganic humin constituents that are involved in the retention of aluminum species was evaluated. After extraction and calcination to obtain the ashes (inorganic constituents), humin and ash samples were structurally characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Interaction studies between aluminum-humin and ash-humin were performed in the pH range of 4.0-8.0 and with various contact times. The results of the characterization of humin and ash showed different functional groups present in the structures of these materials. Based on the results of the interaction between humin-aluminum and ash-aluminum, it can be inferred that both the organic and inorganic components of humin are efficient at absorbing aluminum. However, the adsorption isotherms showed that humin and the ashes have different adsorption behaviors. Humin is the only fraction of natural organic matter with a significant inorganic constituent content; it is the fraction least used by researchers in this field and is often discarded as waste. In light of this, the results obtained in this work highlight the importance of humin as a natural adsorbent material. Humin may be promising for the removal of aluminum species in contaminated environments due to the presence of organic and inorganic constituents. PMID- 29567557 TI - Breaking the biomarker code: PD-L1 expression and checkpoint inhibition in advanced NSCLC. AB - BACKGROUND: Lung cancer is the most common cause of cancer-related death among males and the second leading cause among females globally. Checkpoint inhibitors re-engage the immune system to fight cancer. This review evaluates phase III data on the use of checkpoint inhibitors in the treatment of advanced NSCLC and addresses PD-L1 expression in predicting efficacy. METHODS: Six phase III clinical trials investigating checkpoint inhibitors for NSCLC were identified through a search of PubMed (to November 15, 2016) and conference databases, with findings updated from a directed search of eligible studies conducted in January 2018. RESULTS: Significant reductions in the risk of death ranging from 27% to 41% and were observed second-line and beyond. A relationship between PD-L1 expression and survival was apparent in most trials with optimal benefit for the highest expression levels (>=50%). Benefit was also observed at low or no PD-L1 expression levels and in third-line in some studies. Significantly improved PFS was observed for pembrolizumab at high PD-L1 expression levels (>=50%) first line. Immune-related adverse events associated with checkpoint inhibitors are tolerable and rates of pneumonitis may be lower among PD-L1 inhibitors. Use of checkpoint inhibitors for tumors with driver mutations should only be considered after all appropriate targeted therapy and chemotherapy have been exhausted. PD L1 testing presents a valuable tool to guide treatment sequencing and we recommend use of agent-specific PD-L1 tests and respective scoring systems until a standardized, convenient and broadly applicable test is identified. CONCLUSIONS: Checkpoint inhibitors represent a major advance in the treatment of advanced NSCLC and PD-L1 status can inform treatment decisions. PMID- 29567558 TI - Peer support systems and professional identity of student nurses undertaking a UK learning disability nursing programme. AB - This practitioner based action research examines the implementation of the peer assisted study scheme (PASS) and individual peer mentoring in a cohort of first year undergraduate nursing students. It arose out of the desire of a small number of students in one UK university to transfer from the learning (intellectual) disabilities nursing field to other fields. The number of learning disabilities nurses is falling in England, and nursing shortages and student nurse retention generally is an international concern. The peer support was evaluated by 21 completed questionnaires. All the students had found the sessions they attended useful. Four themes emerged from the study. Students reported gains in knowledge around academic skills, placements and their chosen field of nursing; students felt more confident as a result of attending the sessions; students felt supported, and the importance of the peer mentor's interpersonal skills was highlighted; and finally students had valued meeting other students in their chosen field. These findings are discussed with reference to relevant literature. PMID- 29567559 TI - Clinical practices to promote sleep in the ICU: A multinational survey. AB - PURPOSE: To describe sleep assessment and strategies to promote sleep in adult ICUs in ten countries. METHODS: Multicenter, self-administered survey sent to nurse managers. RESULTS: Response rate was 66% with 522 ICUs providing data. 'Lying quietly with closed eyes' was the characteristic most frequently perceived as indicative of sleep by >60% of responding ICUs in all countries except Italy. Few ICUs (9%) had a protocol for sleep management or used sleep questionnaires (1%). Compared to ICUs in Northern Europe, those in central Europe were more likely to have a sleep promoting protocol (p < 0.001), and to want to implement a protocol (p < 0.001). In >80% of responding ICUs, the most common non pharmacological sleep-promoting interventions were reducing ICU staff noise, light, and nurse interventions at night; only 18% used earplugs frequently. Approximately 50% of ICUs reported sleep medication selection and assessment of effect were performed by physicians and nurses collaboratively. A multivariable model identified perceived nursing influence on sleep decision-making was associated with asking patients or family about sleep preferences (p = 0.004). CONCLUSIONS: We found variation in sleep promotion interventions across European regions with few ICUs using sleep assessment questionnaires or sleep promoting protocols. However, many ICUs perceive implementation of sleep protocols important, particularly those in central Europe. PMID- 29567560 TI - Classification of trace elements in tissues from organic and conventional French pig production. AB - This study assesses the impact of the farming system on the levels of copper, zinc, arsenic, cadmium, lead and mercury in pig tissues from three types of production (Organic (n = 28), Label Rouge (n = 12) and Conventional (n = 30)) randomly sampled in different slaughterhouses. All the concentrations were below regulatory limits. In muscles, Cu, Zn and As were measured at slightly higher levels in organic samples but no differences between organic and Label Rouge was observed. Livers from conventional and Label Rouge pig farms exhibited higher Zn and Cd contents than the organic ones, probably due to different practice in zinc or phytase supplementation of fattening diets. Principal component analysis indicated a correlation between Cu and As concentrations in liver and carcass weight, and between Zn and Cd liver levels and lean meat percentage. The linear discriminant analysis succeeded in predicting the farming process on the basis of the lean meat percentage and the liver Cd level. PMID- 29567561 TI - Medical image analysis of knee joint lipoma arborescens and arthroscopic treatment. AB - OBJECTIVE: Arthroscopy is a minimally invasive surgical procedure on a joint in which examination and treatment of knee damage is performed using a surgical device known as the arthroscope. Lipoma arborescens (LA), an infrequent intra articular lesion, originates from mature adipose cells under subsynovial tissue. The synovial membrane is pale yellow with large villous projections. It is caused by various underlying factors. We found many patients with LA and processed them appropriately.The research was implemented to investigate therapeutic effect of semi-automated arthroscopic diagnosis and treatment for knee joint. METHODS: We used the Stryker arthroscopic in surgery that is 4 mm in diameter with angle at 30 degrees . Patients were chosen by biomechanical analysis and scanning mode. All of the patients underwent radiographic imaging examination, Magnetic Resonance Imaging (MRI), Lysholm Score and Visual Analogue Scale (VAS). Arthroscopic limited synovectomy was carried out on these patients. RESULTS: The wound of all patients healed up. The content of follow-up includes: chief complaints, range of motion of knee joint, Visual Analogue Scale (VAS) and Lysholm score. No swollen nor effusion of the infected knee was found in all patients during the follow-up. The postoperative symptom was markedly alleviated in fourteen patients and partially alleviated in one. All patients were satisfied with the therapeutic effect. CONCLUSION: We performed biomechanical analysis based on knee slight flexion and extension. Arthroscopy is an endoscope for the diagnosis and treatment of joint diseases. Semi-automated arthroscopic debridement is good for early and mid-term osteoarthritis with Lipoma arborescens.

AB - The current study investigated whether 4-year-olds used language as a cue to social group membership to infer whether the tool-use behavior of a model needed to be encoded as indicative of the tool's function. We built on children's tendency to treat functions as mutually exclusive, that is, their propensity to refrain from using the same tool for more than one function. We hypothesized that children would form mutually exclusive tool-function mappings only if the source of the function information was a linguistic in-group person (native) as opposed to an out-group (foreign) person. In Experiment 1, participants (N = 39) were presented with four tool-function pairs by a model who had previously spoken either in their native language or in a foreign language. During the test phase, children encountered new purposes for which they could either use the demonstrated tools' color variant or use another equally suitable, as yet unseen, alternative tool. In line with our predictions, children preferred to use the alternative tool for the new function only in the native language condition (native: 63.3%; foreign: 42.7%). Experiment 2 replicated the initial finding using another foreign language and demonstrated that the lack of mutually exclusive tool choice in the foreign condition did not originate from children's failure to encode the demonstration. These findings suggest that children restrict learning artifact functions from linguistic in-group models. The mutual exclusivity principle in the domain of function learning is used more flexibly than previously proposed.

AB - Vicenin-2, a C-glycoside flavone that is present in many plant sources, exerts potent anti-inflammatory effects in a number of cell and animal models of inflammation. Ten-eleven translocation (TET)-2 has recently gained considerable attention due to the role it plays in regulating the inflammasome. We studied the ability of Vicenin-2 (V-2) to regulate a range of lipopolysaccharide (LPS) stimulated inflammatory activities in PMA-differentiated THP-1 cells and human primary mononuclear cells. We also investigated the action of V-2 on the secretion of NLRP3 inflammasome regulated cytokines (IL-1beta and IL-18) by ELISA, and determined if V-2 can regulate the expression of NLRP3, IL-10, IL-1Ra and TET-2. The effect of V-2 on NF-kappaB signalling was investigated by fluorescence microscopy and gene reporter assay. Additionally, the effect of V-2 on LPS-induced phosphorylation of IKB-alpha was also investigated by Western blot analysis. V-2 down-regulated LPS-induced secretion of proinflammatory cytokines (TNF-alpha and IL-1beta), in both THP-1 and primary mononuclear cells. V-2 also decreased the LPS-stimulated secretion of IL-18 in THP-1 cells. V-2 significantly down-regulated TNF-alpha induced NF-kappaB reporter activity in HEK293T transfected cells and attenuated IKB-alpha phosphorylation in THP-1 cells. V-2 treatment also induced enhanced nuclear staining of the p50 subunit and reduced p65 subunit of NF-kappaB. V-2 treatment alone increased the expression of anti inflammatory cytokine, IL-10, and the regulator of the inflammasome; IL-1Ra, in the presence of LPS. V-2 also significantly decreased LPS-induced NLRP3 expression while concomitantly increasing TET-2 expression. This study demonstrates that the anti-inflammatory actions of V-2 are associated not only with increased IL-10 and IL-1Ra expression, but also with TET-2 up-regulation. Further work is required to establish if the effects of V-2 can be definitively linked to TET-2 activity and that these actions are mirrored in a range of relevant cell types.

AB - miRNAs are among the novel biomarkers that can be evaluated for sensitive and early cancer diagnosis. In the present study, an electrochemical nanobiosensor has been fabricated to detect two gastric cancer (GC) related miRNAs simultaneously. By employing Au nanoparticles- and CdSe@CdS quantum dots contained magnetic nanocomposites as electrochemical labels along with the polythiophene/reduced graphene oxide-modified carbon electrodes, this dual signal nanobiosensor showed a considerable performance in quantifying miR-106a (a GC oncogenic miRNA) and let-7a (a GC tumor suppressor miRNA). Using cyclic voltammetry (CV) and differential pulse voltammetry (DPV), not only the accomplishment of desired biosensing platform construction was confirmed, but also its great specificity, appropriate selectivity, acceptable stability, and significant sensitivity were indicated. Through the combined analyses of the dual miRNAs, our nanobiosensor reached detection limit of 0.02 fM and 0.06 fM for let 7a and miR-106a, respectively. This multiplex PCR-free miRNA nanobiosensor demonstrates attractive potentials for promising applications in early diagnosis of GC and additionally the screen of any miRNA sequence. PMID- 29567565 TI - Silver decahedral nanoparticles empowered SPR imaging-SELEX for high throughput screening of aptamers with real-time assessment. AB - A highly efficient method for aptamer screening with real-time monitoring of the SELEX process was described by silver decahedra nanoparticles (Ag10-NPs) enhanced surface plasmon resonance imaging (SPRI). A microarray chip was developed by immobilization of target protein (Lactoferrin (Lac)) and control proteins (alpha lactalbumin (alpha), beta-lactoglobulin (beta), casein, and bovine serum albumin (BSA)) on the biochip surface. Ag10-NPs were conjugated with an ssDNA library (lib) (Ag10-NPs-library) that consisted of a central 40 nt randomized sequence and a 20 nt fixed primer sequence. Introduction of the Ag10-NPs-library to the SPRI flow channels drastically increased the sensitivity of SPRI signal for real time monitoring of SELEX. The work allows rapid screening of potential targets, and yields nine aptamers with high affinity (nanomolar range) for Lac after only six-rounds of selection. The aptamer Lac 13-26 was then further tested by SPRI, and the results demonstrated that the aptamer had the capacity to be ultra sensitive for specific detection of Lac. The novel SPRI-SELEX method demonstrated here showed many advantages of real-time evaluation, high throughput, and high efficiency. PMID- 29567566 TI - Wirelessly powered and remotely controlled valve-array for highly multiplexed analytical assay automation on a centrifugal microfluidic platform. AB - In this paper we present a wirelessly powered array of 128 centrifugo-pneumatic valves that can be thermally actuated on demand during spinning. The valves can either be triggered by a predefined protocol, wireless signal transmission via Bluetooth, or in response to a sensor monitoring a parameter like the temperature, or homogeneity of the dispersion. Upon activation of a resistive heater, a low-melting membrane (ParafilmTM) is removed to vent an entrapped gas pocket, thus letting the incoming liquid wet an intermediate dissolvable film and thereby open the valve. The proposed system allows up to 12 heaters to be activated in parallel, with a response time below 3 s, potentially resulting in 128 actuated valves in under 30 s. We demonstrate, with three examples of common and standard procedures, how the proposed technology could become a powerful tool for implementing diagnostic assays on Lab-on-a-Disc. First, we implement wireless actuation of 64 valves during rotation in a freely programmable sequence, or upon user input in real time. Then, we show a closed-loop centrifugal flow control sequence for which the state of mixing of reagents, evaluated from stroboscopically recorded images, triggers the opening of the valves. In our last experiment, valving and closed-loop control are used to facilitate centrifugal processing of whole blood. PMID- 29567567 TI - Molecularly imprinted sensor based on Russian Matryoshka structured molecules for enhanced specific identification and double amplification in ultra-trace Tb3+ determination. AB - The selective and sensitive detection of rare earth elements is thought to be difficult because the concentration of those elements in the sample is commonly at a low level and they normally have severe mutual interference which is caused by homologous chemical properties. In this study, a novel molecularly imprinted polymer (MIP) sensor was fabricated for highly sensitive and selective determination of ultra-trace Tb3+. The Tb3+-ethylenediaminetetraacetic acid complex (Tb-EDTA) as the template molecule was incorporated into mono-6-mercapto beta-cyclodextrin (mono-6-SH-beta-CD) to form a Russian Matryoshka (RM) structured molecule (CD/Tb-EDTA). Titanium isopropoxide was utilized in vapor sol gel polymerization to construct MIP membrane. Moreover, the selectivity of the RM MIP sensor was remarkably enhanced by the "triple-selectivity" recognition of EDTA-to-Tb3+, beta-CD-to-(Tb-EDTA), and 3D cavity-to-(CD/Tb-EDTA), while the sensitivity of the MIP sensor was significantly improved by ECL signal enhancement based on double amplification, in other words, the electrochemiluminescence resonance energy transfer (ECL-RET) between the ECL donor of CD/Tb-EDTA and the ECL acceptor of Ru(bpy)32+, and the ECL enhancement by the co-reactant of CD/Tb-EDTA on Ru(bpy)3Cl2. When the imprinted cavities were occupied by Tb-EDTA during rebinding, the host-guest inclusion structured complex was formed and the ECL intensities produced by the Ru(bpy)3Cl2 ECL system increased with increasing concentration of Tb-EDTA. The proposed sensor was used for quantitative analysis of Tb3+ with concentrations ranging from 8.00 * 10-13 mol/L to 4.00 * 10-9 mol/L and successfully applied to detect Tb3+ in seawater samples. The detection limit of the sensor was found to be 3.90 * 10-13 mol/L (DL = 3deltab/K), which is lower than previously reported values. Thus, the fabricated sensor is feasible for practical applications. PMID- 29567568 TI - Hybridization conditions of oligonucleotide-capped gold nanoparticles for SPR sensing of microRNA. AB - MicroRNA (miRNA) sensing, especially the miRNA-200 family, is increasingly targeted for cancer diagnostics. As the sensing schemes often rely on nanoparticles functionalized with a specific oligonucleotide, we investigate the hydribization conditions using the common case of surface plasmon resonance (SPR) sensing of miRNA and a gold nanoparticle (Au NP) competitor. In this type of assays, the Au NPs compete with the microRNA to bind the capture probe immobilized on the gold surface. In our study, we simplify and improve the detection procedure by adopting 11-mercaptoundecanoic acid (11-MUA) as linker to the gold surface, not only omitting the blocking step of 6-mercapto-1-hexanol (MCH), but also increasing the probe density. We report that the response in our SPR sensing studies increased with the size of Au NPs according to the plasmon ruler equation, but the larger AuNPs of 32 nm lacked colloidal stability. In addition, decreasing the ratio of oligonucleotide to Au NPs and the addition of polyethylene glycol (PEG) to hybridization buffer also favored a better response in SPR sensing of miRNA. The optimization led to an improved detection sensitivity in our competition method and a detection limit as low as 500 pM for miRNA-200b without amplification of miRNA and use of other amplification schemes. PMID- 29567569 TI - Ipsilateral stress fracture of the proximal fibula after total knee arthroplasty in a patient with severe valgus knee deformity on a background of Rheumatoid arthritis. AB - INTRODUCTION: Previous studies have reported a lower extremity stress fracture after total knee arthroplasty (TKA). However, a fibular fracture after TKA is quite rare. We report a case of proximal fibula fracture after TKA in a patient with rheumatoid arthritis (RA). PRESENTATION OF CASE: A 45 year old woman with RA had severe knee and foot pain with an antalgic gait disturbance. There was a significant joint deformity in many of lower limb joints. Interval bilateral TKAs were performed two weeks apart. Right TKA was performed using a constraint-type prosthesis, through lateral parapatellar approach. Left TKA was performed using a posterior-stabilized (PS) prosthesis through the more commonly employed, medial parapatellar approach. Seven weeks after the right TKA, the patient was found to have an atraumatic proximal fibular fracture. The fracture went on to heal conservatively. DISCUSSION: The fracture was considered to have occurred after the TKA. The callus appeared eleven weeks after the TKA. The factors that contributed to the fracture were thought to be overload of the fragile bone secondarily to disuse osteopaenia, RA or potentially the significant valgus malalignment correction. The surgical approach, the implant or implantation or the persisting joint deformity, were thought to be contributing factors to the aetiology of the stress fracture. The resultant change in clinical outcome/course is outlined in this case report. CONCLUSION: A stress fracture of the proximal fibula has the potential in the aetiology of may cause other stress fractures, joint other instability, and/or malalignment of the total lower extremity. PMID- 29567570 TI - Coating process optimization through in-line monitoring for coating weight gain using Raman spectroscopy and design of experiments. AB - In this study the authors developed a real-time Process Analytical Technology (PAT) of a coating process by applying in-line Raman spectroscopy to evaluate the coating weight gain, which is a quantitative analysis of the film coating layer. The wide area illumination (WAI) Raman probe was connected to the pan coater for real-time monitoring of changes in the weight gain of coating layers. Under the proposed in-line Raman scheme, a non-contact, non-destructive analysis was performed using WAI Raman probes with a spot size of 6 mm. The in-line Raman probe maintained a focal length of 250 mm, and a compressed air line was designed to protect the lens surface from spray droplets. The Design of Experiment (DOE) was applied to identify factors affecting the Raman spectra background of laser irradiation. The factors selected for DOE were the strength of compressed air connected to the probe, and the shielding of light by the transparent door connecting the probe to the pan coater. To develop a quantitative model, partial least squares (PLS) models as multivariate calibration were developed based on the three regions showing the specificity of TiO2 individually or in combination. For the three single peaks (636 cm-1, 512 cm-1, 398 cm-1), least squares method (LSM) was applied to develop three univariate quantitative analysis models. One of best multivariate quantitative model having a factor of 1 gave the lowest RMSEP of 0.128, 0.129, and 0.125, respectively for prediction batches. When LSM was applied to the single peak at 636 cm-1, the univariate quantitative model with an R2 of 0.9863, slope of 0.5851, and y-intercept of 0.8066 had the lowest RMSEP of 0.138, 0.144, and 0.153, respectively for prediction batches. The in line Raman spectroscopic method for the analysis of coating weight gain was verified by considering system suitability and parameters such as specificity, range, linearity, accuracy, and precision in accordance with ICH Q2 regarding method validation. The proposed in-line Raman spectroscopy can be utilized as a PAT for product quality assurance as it offers real-time monitoring of quantitative changes in coating weight gain and process end-points during the film coating process. PMID- 29567571 TI - Development of a HILIC method for the determination of 5-fluorouracil from nano drug delivery systems and rat skin extracts. AB - This is the first report in literature using hydrophilic interaction liquid chromatography (HILIC) in combination with diode array detector (DAD) for stability indicating determination of 5-Fluorouracil (5-FU) from its bulk form, pharmaceutical preparations, developed solid lipid nanoparticle (SLN) and nano structured lipid carrier (NLC) drug delivery systems as well as the rat skin extracts. The separation was performed at 45 degrees C, on Sequant Zic HILIC (250 mm * 4.60 mm ID, 5 MUm, 200 Ao), peek HPLC column. Mobile phase is consisting of a mixture of acetonitrile: buffer containing 5 mM ammonium acetate (95:5; v/v). The pH of the mobile phase was adjusted to 7.0 using 1 M NaOH. The analysis was carried out at 0.75 mL min-1 flow rate with a detection wavelength of 265 nm and the injection volume was arranged as 10 MUL. The developed method was fully validated in accordance with the International Council on Harmonization (ICH) Guidelines. Specificity of this method was demonstrated by forced degradation studies. As a result of calibration studies, the calibration curve was found linear in the concentration range of 1-250 MUg mL-1 (R2 = 0.999). The precision of this technique calculated within the frame of intra-day and inter day based on a percentage of relative standard deviation (RSD%) values (<2%). The limits of detection and quantification were 11 and 37 ng mL-1 respectively. On the other hand, 5-FU loaded SLN and NLC formulations with average particle size of 370 nm were also developed and compared in order to increase the permeation of drug into the rat skin. Ex-vivo Penetration/Permeation Studies indicated that higher dermal accumulation of 5-FU was obtained with NLC formulation. As a conclusion, the present work expressed the optimization and the validation of a selective, simple, precise and accurate fully validated HILIC method with sufficient sensitivity for the estimation of 5-FU in raw materials, marketed formulation and rat skin extract after applying both of the commercial product and newly developed nanoparticulate drug delivery systems on to the rat skins with high percentage recoveries.

AB - Drug repurposing has been an emerging therapeutic strategy, which involves exploration of a new therapeutic approach for the use of an existing drug. Glibenclamide (Gli) is an anti-diabetic sulfonylurea drug extensively used for the treatment of type-2 diabetes, it has also been shown to possess anti proliferative effect against several types of tumors. The present study was executed to understand the mechanisms underlying the interaction of Gli with DNA under physiological conditions. The binding mechanism of Gli with DNA was scrutinized by UV-vis absorption spectroscopy and fluorescence emission spectroscopy. The conformational changes and electrochemical properties were analyzed by circular dichroism spectroscopy and cyclic voltammetry. Isothermal titration calorimetry was employed to examine the thermodynamic changes and molecular docking technique used to analyze the interaction mode of Gli with DNA. The spectroscopic studies revealed that Gli interacts with DNA through groove binding mode. Further, isothermal titration calorimetry depicted a stronger mode of interaction favorably groove-binding. Recently, systemic combination therapy has shown significant promise in inhibiting multiple targets simultaneously yielding high therapeutic competence with lesser side effects. With this concern, we intended to study the combined cytotoxicity of Gli with doxorubicin (Dox). The results of MTT assay and acridine orange (AO)/ethidium bromide (EtBr) staining showed synergistic cytotoxicity of Gli + Dox combination on HepG2 & A549 cells. The present study documents the intricate mechanism of Gli-DNA interaction and delivers a multifaceted access for chemotherapy by Gli + Dox combination. PMID- 29567573 TI - 1H NMR-based metabolomics approach to investigate the urine samples of collagen induced arthritis rats and the intervention of tetrandrine. AB - Tetrandrine is an effective ingredient isolated from the roots of a frequently used medicinal plant Stephania tetrandra S. Moore. It has been used for the management of arthritis in China, but the precise mechanism remains unclear. In the present study, a metabolomics method based on the 1H NMR was constituted to quantify the alterations of the endogenous metabolites in the urines of collagen induced arthritis (CIA) rats treated with tetrandrine. Data showed that tetrandrine treatment could alleviate the ankle joint swelling and ameliorate histopathological changes in rats. The metabonomic analysis indicated that 23 potential biomarkers in urine were affiliated with CIA. They mainly participated in energy metabolism, amino acid metabolism, lipid metabolism and gut microbe metabolism. Moreover, our results implied that tetrandrine could reverse the pathological process of CIA through adjusting the unbalanced metabolic pathways. Thus, these metabolic pathways and potential biomarkers might be the potential therapeutic targets of tetrandrine, and these findings supplied new visions into the protective effect of tetrandrine against arthritis in rats. PMID- 29567574 TI - Fast identification of anticancer constituents in Forsythiae Fructus based on metabolomics approaches. AB - An herb commonly contains hundreds of constituents. Identification of bioactive compound(s) in each herb using conventional approaches is usually inefficient and eco-unfriendly. In this study, we aimed to fast identify anticancer compounds in Forsythiae Fructus using UPLC/MS-based metabolomics analysis. We firstly fractionated Forsythiae Fructus crude extracts with organic solvents of different polarity, then the chemical profile of each fraction was analyzed by UPLC/Q TOF/MS, and the anticancer activity profiles of all fractions were determined by MTT assay. Next, orthogonal projections to latent structures discriminant analysis (OPLS-DA) was applied to discriminate fractions with different anticancer activity to determine the compound(s) that contributes most to the anticancer activity. Betulinic acid was then identified to be the most potent anticancer compound in Forsythiae Fructus. Its predicted anticancer activity was confirmed by MTT assay. Taken together, our results demonstrated that the present integrated metabolomics strategy could be used for fast identification of anticancer compound(s) in herb extracts or other complex mixtures of chemicals. PMID- 29567575 TI - Comparative studies on the human serum albumin binding of the clinically approved EGFR inhibitors gefitinib, erlotinib, afatinib, osimertinib and the investigational inhibitor KP2187. AB - Binding interactions between human serum albumin (HSA) and four approved epidermal growth factor receptor (EGFR) inhibitors gefitinib (GEF), erlotinib (ERL), afatinib (AFA), osimertinib (OSI), as well as the experimental drug KP2187, were investigated by means of spectrofluorometric and molecular modelling methods. Steady-state and time resolved spectrofluorometric techniques were carried out, including direct quenching of protein fluorescence and site marker displacement measurements. Proton dissociation processes and solvent dependent fluorescence properties were investigated as well. The EGFR inhibitors were predominantly presented in their single protonated form (HL+) at physiological pH except ERL, which is charge-neutral. Significant solvent dependent fluorescence properties were found for GEF, ERL and KP2187, namely their emission spectra show strong dependence on the polarity and the hydrogen bonding ability of the solvents. The inhibitors proved to be bound at site I of HSA (in subdomain IIA) in a weak-to-moderate fashion (logK' 3.9-4.9) using spectrofluorometry. OSI (logK' 4.3) and KP2187 can additionally bind in site II (in subdomain IIIA), while GEF, ERL and AFA clearly show no interaction here. Docking methods qualitatively confirmed binding site preferences of compounds GEF and KP2187, and indicated that they probably bind to HSA in their neutral forms. Binding constants calculated on the basis of the various experimental data indicate a weak-to-moderate binding on HSA, only OSI exhibits somewhat higher affinity towards this protein. However, model calculations performed at physiological blood concentrations of HSA resulted in high (ca. 90%) bound fractions for the inhibitors, highlighting the importance of plasma protein binding. PMID- 29567576 TI - The human natural killer-1 (HNK-1) glycan mimetic ursolic acid promotes functional recovery after spinal cord injury in mouse. AB - Human natural killer-1 (HNK-1) cell antigen is a glycan epitope involved in several neural events, such as neuritogenesis, myelination, synaptic plasticity and regeneration of the nervous system after injury. We have recently identified the small organic compound ursolic acid (UA) as a HNK-1 mimetic with the aim to test its therapeutic potential in the central nervous system. UA, a plant-derived pentacyclic triterpenoid, is well known for its multiple biological functions, including neuroprotective, antioxidant and anti-inflammatory activities. In the present study, we evaluated its functions in a mouse model of spinal cord injury (SCI) and explored the molecular mechanisms underlying its positive effects. Oral administration of UA to mice 1 h after SCI and thereafter once daily for 6 weeks enhanced the regaining of motor functions and axonal regrowth, and decreased astrogliosis. UA administration decreased levels of proinflammatory markers, including interleukin-6 and tumor necrosis factor-alpha, in the injured spinal cord at the acute phase of inflammation and activated the mitogen-activated protein kinase and phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin pathways in the injured spinal cord. Taken together, these results suggest that UA may be a candidate for treatment of nervous system injuries. PMID- 29567577 TI - Development of atherosclerotic-moyamoya syndrome with genetic variant of RNF213 p.R4810K and p.T1727M: A case report. AB - OBJECTIVE: We report a rare case of atherosclerotic-moyamoya syndrome (A-MMS) in an adult female with genetic variant of both ring finger 213 (RNF213) p.R4810K and p.T1727M. CASE REPORT: A 46-year-old previously healthy, right-handed woman displayed transient slurred speech, which started to worsen four years ago. Initial magnetic resonance angiography (MRA) revealed stenosis in left middle cerebral artery (MCA), bilateral anterior cerebral artery (ACA), and left posterior cerebral artery (PCA). The patient subsequently underwent catheter angiography, which confirmed the formation of moyamoya vessels, with Suzuki's angiographic staging of grade-3 on the left side. Although the patient had been on both anti-platelet and statin therapy at the time, a follow-up examination showed further exacerbation of left MCA stenosis, along with enhanced moyamoya vessel formation. On black-blood imaging using DANTE-SPACE, there were eccentric, evolving lesions in the left MCA. We next screened for potential genetic variants, using genomic DNA samples isolated from both the patient and her immediate family members. The results showed that the patient, along with her mother, sister, and brother, possessed the heterozygous variant of the RNF213 gene, including c.14429G > A (p.R4810K) and c.5180C > T (p.T1727M). The patient's daughter did not have the variant. CONCLUSION: Collectively, we present a unique case of A-MMS with genetic variant of RNF213 p.R4810K and p.T1727M, manifesting as progression. Based on the family tree, these two mutations are on the same RNF213 haplotype. Whether atherosclerosis is the cause of A-MMS or it further exacerbates the injury of MMD to the A-MMS patients with RNF213 gene variant is a question to be investigated.

AB - OBJECTIVE: To investigate the relationship between the expression of microtubule associated protein LC3 and the numbers of CD68 + microglia, CD4 + T lymphocytes and CD8 + T lymphocytes, as well as the clinical significance of those factors in gliomas. PATIENTS AND METHODS: The study group consisted of 127 patients with gliomas who were operated to our hospital, we examined the expression of LC3 by Immunohistochemistry and Western blot, and we assessed the numbers of CD68 + microglia, CD4 + T lymphocytes and CD8 + T lymphocytes by Immunohistochemistry, we analyze the relationship between all the factors and explore the significance. RESULTS: Immunohistochemistry and Western blotting showed that the expression of LC3 in normal brain tissue, low-grade gliomas, and high-grade gliomas are elevated to varying degrees (P < 0.01); Immunohistochemical detection showed that the numbers of CD68 + microglia, CD4 + T lymphocytes and CD8 + T lymphocytes in gliomas was higher than that in normal brain tissues (P < 0.01), and the high grade gliomas were higher than those in low-grade gliomas (P < 0.01); The results of Spearman correlation showed that the expression of LC3 was positively correlated with the numbers of CD68 + microglia, CD4 + T lymphocytes, and CD8 + T lymphocytes (P < 0.05); Furthermore, survival analysis showed that LC3, CD68 + microglia, CD8 + T lymphocytes and tumor grade were independent prognostic factors of glioma. CONCLUSIONS: LC3 may be one of the factors that affect the tumor cellular immunity response in gliomas. The simultaneous detection of LC3, CD68 + microglia and CD8 + T lymphocytes can be used to assess the prognosis of glioma. PMID- 29567579 TI - Palliative shunt surgery for patients with leptomeningeal metastasis. AB - OBJECTIVES: Leptomeningeal metastasis (LM) is associated with poor prognosis and affects the quality of life (QOL) of end-stage cancer patients. Severe headache associated with hydrocephalus causes reduced QOL. We investigated the clinical value of surgical treatment for hydrocephalus in LM patients. PATIENTS AND METHODS: The medical records of 11 consecutive patients who underwent lumboperitoneal shunt (LPS) or ventriculoperitoneal shunt (VPS) at our institution between 2007 and 2016 were investigated. Primary brain tumor patients were excluded. We assessed the neurological status and therapeutic effects at 1 month after the shunt surgery. RESULTS: The patients were three males and eight females with a median age of 58 years (interquartile range [IR] 52-68 years). The median preoperative neutrophil-to-lymphocyte ratio was 6.4 (IR 4.8-9.2). Symptom improvement was observed in nine patients, and severe headache was relieved in seven (88%) out of eight patients. The median Karnofsky performance status scale increased from 40 to 60, and the median overall survival after primary malignancy diagnosis was 27.4 months (IR 19.6-63.1 months). The median survival after the diagnosis of brain parenchymal metastasis, LM, and shunt surgery were 7.2 months (IR 5.1-14.1 months), 3.9 months (IR 3.5-6.3 months), and 3.3 months (IR 2.9-5.7 months), respectively. CONCLUSION: Shunt surgery for hydrocephalus could offer an effective palliative surgical option for symptom relief especially relief of severe headache, contributing improvement of QOL in LM patients. PMID- 29567580 TI - Nano-spectroscopic imaging of proteins with near-field scanning optical microscopy (NSOM). AB - Understanding the hierarchical structure of proteins at their fundamental length scales is essential to get insights into their functions and roles in fundamental biological processes. Near-field scanning optical microscopy (NSOM), which overcomes the diffraction limits of conventional optics, provides a powerful analytical tool to image target proteins at nanoscale resolution. Especially, by combining NSOM with infrared (IR) or Raman spectroscopy, near-field nanospectroscopic imaging of a single protein is achieved. In this review, we present the recent technical progress of NSOM setup for nanospectroscopic imaging of proteins, and its application to nanospectroscopic analysis of protein structures is highlighted and critically reviewed. Finally, current challenges and perspectives on application of NSOM in emerging areas of industrial, environmental and medical biotechnology are discussed. PMID- 29567581 TI - Metabolomics tools for the synthetic biology of natural products. AB - Metabolomics plays an increasingly central role within the Design-Build-Test cycle of synthetic biology, in particular in applications targeting the discovery, diversification and optimised production of a wide range of natural products. For example, improved methods for the online monitoring of chemical reactions accelerate data generation to be compatible with the rapid iterations and increasing library sizes of automated synthetic biology pipelines. Combinations of label-free metabolic profiling and 13C-based flux analysis lead to increased resolution in the identification of metabolic bottlenecks affecting product yield in engineered microbes. And molecular networking strategies drastically increase our ability to identify and characterise novel chemically complex biomolecules of interest in a diverse range of samples. PMID- 29567583 TI - Event-related brain potentials elicited by high-speed cooling of the skin: A robust and non-painful method to assess the spinothalamic system in humans. AB - OBJECTIVE: To investigate whether cool-evoked potentials (CEP) elicited by brisk innocuous cooling of the skin could serve as an alternative to laser-evoked potentials (LEP), currently considered as the best available neurophysiological tool to assess the spinothalamic tract and diagnose neuropathic pain. METHODS: A novel device made of micro-Peltier elements and able to cool the skin at -300 degrees C/s was used to record CEPs elicited by stimulation of the hand dorsum in 40 healthy individuals, characterize the elicited responses, and assess their signal-to-noise ratio. Various stimulation surfaces (40 mm2 and 120 mm2), cooling ramps (-200 degrees C/s and -133 degrees C/s) and temperature steps (20 degrees C, 15 degrees C, 10 degrees C, 5 degrees C) were tested to identify optimal stimulation conditions. RESULTS: CEPs were observed in all conditions and subjects, characterized by a biphasic negative-positive complex maximal at the vertex (Cz), peaking 190-400 ms after stimulus onset, preceded by a negative wave over central-parietal areas contralateral to the stimulated hand. Their magnitude was modulated by stimulation surface, cooling ramp and temperature step. CONCLUSION: Rapid innocuous skin cooling elicits robust CEPs at latencies compatible with the conduction velocity of Adelta-fibers. SIGNIFICANCE: CEPs can be a complementary tool to the recording of LEPS for assessing the function of small-diameter Adelta-fibers and the spinothalamic tract.

AB - OBJECTIVE: This study aims to use the activities recorded directly from the deep brain stimulation (DBS) electrode to address the focality and distinct nature of the local field potential (LFP) activities of different frequency. METHODS: Pre operative and intra-operative magnetic resonance imaging (MRI) were acquired from patients with Parkinson's disease (PD) who underwent DBS in the subthalamic nucleus and intra-operative LFP recording at rest and during cued movements. Images were reconstructed and 3-D visualized using Lead-DBS(r) toolbox to determine the coordinates of contact. The resting spectral power and movement related power modulation of LFP oscillations were estimated. RESULTS: Both subthalamic LFP activity recorded at rest and its modulation by movement had focal maxima in the alpha, beta and gamma bands. The spatial distribution of alpha band activity and its modulation was significantly different to that in the beta band. Moreover, there were significant differences in the scale and timing of movement related modulation across the frequency bands. CONCLUSION: Subthalamic LFP activities within specific frequency bands can be distinguished by spatial topography and pattern of movement related modulation. SIGNIFICANCE: Assessment of the frequency, focality and pattern of movement related modulation of subthalamic LFPs reveals a heterogeneity of neural population activity in this region. This could potentially be leveraged to finesse intra-operative targeting and post-operative contact selection. PMID- 29567584 TI - Interaction between striatal volume and DAT1 polymorphism predicts working memory development during adolescence. AB - There is considerable inter-individual variability in the rate at which working memory (WM) develops during childhood and adolescence, but the neural and genetic basis for these differences are poorly understood. Dopamine-related genes, striatal activation and morphology have been associated with increased WM capacity after training. Here we tested the hypothesis that these factors would also explain some of the inter-individual differences in the rate of WM development. We measured WM performance in 487 healthy subjects twice: at age 14 and 19. At age 14 subjects underwent a structural MRI scan, and genotyping of five single nucleotide polymorphisms (SNPs) in or close to the dopamine genes DRD2, DAT-1 and COMT, which have previously been associated with gains in WM after WM training. We then analyzed which biological factors predicted the rate of increase in WM between ages 14 and 19. We found a significant interaction between putamen size and DAT1/SLC6A3 rs40184 polymorphism, such that TC heterozygotes with a larger putamen at age 14 showed greater WM improvement at age 19. The effect of the DAT1 polymorphism on WM development was exerted in interaction with striatal morphology. These results suggest that development of WM partially share neuro-physiological mechanism with training-induced plasticity. PMID- 29567585 TI - Paraganglioma in an explanted heart. PMID- 29567586 TI - Obesity and risk for venous thromboembolism from contemporary therapy for pediatric acute lymphoblastic leukemia. AB - INTRODUCTION: Acute lymphoblastic leukemia (ALL) therapy confers risk for venous thromboembolism (VTE) and associated acute and long-term morbidity. Obesity increases VTE risk in the general population but its impact on ALL therapy associated VTE is unknown. METHODS: In a retrospective cohort of children treated for ALL between 2008 and 2016 (n = 294), we analyzed obesity at diagnosis (body mass index [BMI] >=95%) and subsequent development of VTE. A subset participated in two concurrent prospective ALL trials studying body composition via dual energy X-ray absorptiometry (DXA) (n = 35) and hypercoagulability via thromboelastography (TEG) (n = 46). Secondary analyses explored whether precise measurement of body fat and/or global hemostasis ex vivo by TEG could further delineate VTE risk in the obese. RESULTS: Overall, we found 27/294 (9.2%) patients developed symptomatic VTE during therapy, 19/27 (70%) occurred during Induction. Study-defined "serious" VTE developed in 4/294 (1.4%) of patients. Obesity but not overweight was strongly predictive of symptomatic VTE (obesity odds ratio = 3.8, 95% confidence interval 1.5-9.6, p = 0.008). In the DXA subset, only 2/35 patients developed symptomatic VTE. However, within those prospectively screened during Induction, 30% (14/46) developed VTE; eight (17%) of these were asymptomatic and found only via screening. CONCLUSIONS: In this pediatric ALL cohort, obesity conferred more than a three-fold increased risk for symptomatic VTE. In a subgroup of patients who underwent active screening, up to a third were noted to have VTE (symptomatic and asymptomatic). TEG did not predict VTE. Additional studies are necessary to validate these findings and to further refine a risk-stratified approach to thrombo-prevention during ALL therapy.

AB - We consider in review current state-of-the-art fluorescence microscopy for investigating the host-pathogen interface. Our perspective is honed from years with literally thousands of microbiologists using the variety of imaging technologies available within our dedicated BSL2/BSL3 optical imaging research service facilities at the Institut Pasteur Paris founded from scratch in 2001. During fifteen years learning from the success and failures of introducing different fluorescence imaging technologies, methods, and technical development strategies we provide here a synopsis review of our experience to date and a synthesis of how we see the future in perspective for fluorescence imaging at the host-pathogen interface. PMID- 29567589 TI - Time-to-collision analysis of pedestrian and pedal-cycle accidents for the development of autonomous emergency braking systems. AB - The aim of this study was to describe the position of pedestrians and pedal cyclists relative to the striking vehicle in the 3 s before impact. This information is essential for the development of effective autonomous emergency braking systems and relevant test conditions for consumer ratings. The UK RAIDS OTS study provided 175 pedestrian and 127 pedal-cycle cases based on in-depth, at scene investigations of a representative sample of accidents in 2000-2010. Pedal cyclists were scattered laterally more widely than pedestrians (90% of cyclists within around +/-80 degrees compared to +/-20 degrees for pedestrians), however their distance from the striking vehicle in the seconds before impact was no greater (90% of cyclists within 42 m at 3 s compared to 50 m for pedestrians). This data is consistent with a greater involvement of slow moving vehicles in cycle accidents. The implication of the results is that AEB systems for cyclists require almost complete 180 degrees side-to-side vision but do not need a longer distance range than for pedestrians. PMID- 29567590 TI - Azithromycin ameliorates OVA-induced airway remodeling in Balb/c mice via suppression of epithelial-to-mesenchymal transition. AB - Azithromycin is a potent agent that prevents airway remodeling. In this study, we hypothesized that azithromycin (35 mg/kg orally) alleviated airway remodeling through suppression of epithelial-to-mesenchymal transition (EMT) via downregulation of transforming growth factor-beta 1 (TGF-beta1)/receptor for activated C-kinase1 (RACK1)/snail in mice. An ovalbumin (OVA)-induced Balb/c mice airway allergic inflammatory model was used. Airway inflammation and remodeling were evaluated with hematoxylin and eosin (HE), periodic acid-Schiff (PAS), and Masson staining. E-cadherin and N-cadherin (molecular markers of EMT) were analyzed by immunofluorescence, quantitative reverse transcriptase polymerase chain reaction (qRT-PCR), and western blotting; alpha-smooth muscle actin (alpha SMA) was evaluated using immunohistochemistry (IHC), qRT-PCR, and western blotting; and expression of TGF-beta1/RACK1/Snail in lungs was measured by qRT PCR and western blotting. Our data showed that azithromycin significantly reduced inflammation score, peribronchial smooth muscle layer thickness, goblet cell metaplasia, and deposition of collage fibers (P < 0.05), and effectively suppressed airway EMT (upregulated E-cadherin level, and downregulated N-cadherin and alpha-SMA levels) compared with the OVA group (P < 0.05). Moreover, the increasing mRNA and protein expressions of TGF-beta1 and RACK1 and mRNA level of Snail in lung tissue were all significantly decreased in azithromycin-treated mice (P < 0.05). Taken together, our results suggest that azithromycin has the greatest effects on reducing airway remodeling by inhibiting TGF beta1/RACK1/Snail signal and improving the EMT in airway epithelium. PMID- 29567591 TI - Protective effects of ginsenoside Rg1 on splenocytes and thymocytes in an aging rat model induced by d-galactose. AB - Physiological aging is associated with a range of medical problems. However, the treatment of aging-associated diseases and prolonging human life are vital to our current aging societies. Panax ginseng, a traditional Chinese medicine, has been shown to have anti-oxidative and anti-aging effects. In the current study, aging rats induced by d-galactose were administered ginsenoside Rg1, then splenocytes and thymocytes were extracted and changes in activity were detected. The results demonstrated that compared with the d-gal group, the level of advanced glycation end products (AGE), the ratio of splenocytes and thymocytes in G0 phase (%), and apoptosis (%) of splenocytes and thymocytes, the ratio (%) of SA-gal positive splenocytes and thymocytes, the content of reactive oxygen species (ROS) and malondialdehyde (MDA), the ratio of glutathione (GSH) to oxidized glutathione (GSSG) and senescence-associated protein expression were significantly decreased and the index of the spleen and thymus, the proportion of white pulp in the spleen, the proportion of cortex in the thymus, the content of interleukin-2 (IL 2), interleukin-6 (IL-6), granulocyte-macrophage colony stimulating factor (GM CSF), tumor necrosis factor-alpha (TNF-alpha), the activities of superoxide dismutase (SOD), and the proliferative capacity of splenocytes and thymocytes were increased in the Rg1+ d-gal group. These findings demonstrated that ginsenoside Rg1 may antagonize spleen and thymus damage in d-galactose-induced aging rats by alleviating oxidative stress injury and down-regulating the expression of senescence-associated protein. PMID- 29567592 TI - Training students to detect delirium: An interprofessional pilot study. AB - AIM: The purpose of this paper is to report nursing student knowledge acquisition and attitude after completing and interprofessional simulation with medical students. INTRODUCTION: The IOM has challenged healthcare educators to teach teamwork and communication skills in interprofessional settings. Interprofessional simulation provides a higher fidelity experience than simulation in silos. Simulation may be particularly useful in helping healthcare workers gain the necessary skills to care for psychiatric clients. Specifically, healthcare providers have difficulty differentiating between dementia and delirium. Recognizing this deficit, an interprofessional simulation was created using medical students in their neurology rotation and senior nursing students. METHOD: Twenty-four volunteer nursing students completed a pre-survey to assess delirium knowledge and then completed an education module about delirium. Twelve of these students participated in a simulation with medicine students. Pre and Post Kid SIM Attitude questionnaires were completed by all students participating in the simulation. After the simulations were complete, all twenty-four students were asked to complete the post-survey regarding delirium knowledge. RESULTS: While delirium knowledge scores improved in both groups, the simulation group scored higher, but the difference did not reach significance. The simulation group demonstrated a statistically significant improvement in attitudes toward simulation, interprofessional education, and teamwork post simulation compared to their pre-simulation scores. CONCLUSION: Nursing students who participated in an interprofessional simulation developed a heightened appreciation for learning communication, teamwork, situational awareness, and interprofessional roles and responsibilities. These results support the use of interprofessional simulation in healthcare education. PMID- 29567593 TI - Student health professionals' attitudes and experience after watching "Ida's Diary", a first-person account of living with borderline personality disorder: Mixed methods study. AB - BACKGROUND: There is increasing interest in the use of commercial movies in nursing education, or "cinenurducation". There is a need for educational interventions which target mental health nurses' attitudes towards people with borderline personality disorder. OBJECTIVES: To investigate and evaluate the experience and effects of attendance at a screening of the movie Ida's Diary, a first-person account of living with borderline personality disorder. DESIGN: Mixed methods design comprising a within-subjects AB longitudinal survey, and a qualitative analysis of participant-generated data and researcher field notes from a World Cafe discussion group. SETTINGS: One university in Scotland. PARTICIPANTS: N = 66 undergraduate and postgraduate mental health nursing and counselling students. METHODS: Participants completed measures of cognitive and emotional attitudes towards, and knowledge about, people with borderline personality disorder before and after one of two film screenings. We conducted a World Cafe discussion group after the second screening. Resulting data were subject to a qualitative thematic analysis. RESULTS: Quantitative analysis revealed a five-factor cognitive and a single-factor emotional attitude structure. Cognitive-attitudinal items related to treatment deservingness and value of mixed treatment approaches improved across iterations. Total knowledge score did not change, but one item about borderline personality disorder as a precursor to schizophrenia received considerably more incorrect endorsement post screening. Qualitative analysis revealed five themes: Facilitation and inhibition of learning; promotion but not satiation of appetite for knowledge; challenging existing understanding; prompting creativity and anxiety; and initiating thinking about the bigger picture. CONCLUSIONS: Participants found the film thought provoking; it increased their appetite for knowledge. Findings suggest that screening should be delivered in conjunction with more didactic information about borderline personality disorder. PMID- 29567594 TI - Production of bioethanol and value added compounds from wheat straw through combined alkaline/alkaline-peroxide pretreatment. AB - An efficient scheme was developed for the conversion of wheat straw (WS) into bioethanol, silica and lignin. WS was pre-extracted with 0.2 mol/L sodium hydroxide at 30 degrees C for 5 h to remove about 91% of initial silica. Subsequently, the alkaline-pretreated solids were subjected to alkaline hydrogen peroxide (AHP) pretreatment with 40 mg hydrogen peroxide (H2O2)/g biomass at 50 degrees C for 7 h to prepare highly digestible substrate. The results of enzymatic hydrolysis demonstrated that the sequential alkaline-AHP pretreated WS was efficiently hydrolyzed at 10% (w/v) solids loading using an enzyme dosage of 10 mg protein/g glucan. The total sugar conversion of 92.4% was achieved. Simultaneous saccharification and co-fermentation (SSCF) was applied to produce ethanol from the two-stage pretreated substrate using Saccharomyces cerevisiae SR8u strain. Ethanol with concentration of 31.1 g/L was produced. Through the proposed process, about 86.4% and 54.1% of the initial silica and lignin were recovered, respectively. PMID- 29567595 TI - The pH-based fed-batch for lipid production from Trichosporon oleaginosus with crude glycerol. AB - In this study, it was found that the optimal pH for the growth of Trichosporon oleaginosus was related to the fermentation medium. A neutral or weak acid pH condition was optimal for the growth of Trichosporon oleaginosus in the extract peptone-dextrose and wastewater sludge medium. Significant inhibition was observed at neutral pH in the wastewater sludge + crude glycerol medium due to the high soap content of the crude glycerol. By converting the soap to free fatty acid (FFA) at pH 5, the soap inhibition could be prevented. Fed-batch fermentation was employed to produce lipid from Trichosporon oleaginosus at pH 5 controlled by feeding crude glycerol. A remarkably high biomass (65.63 g/L) and lipid (35.79 g/L) concentration were achieved from the pH-based fed-batch fermentation in this study. PMID- 29567596 TI - Techno-economic and profitability analysis of food waste biorefineries at European level. AB - Food waste represents a potential source to produce value-added materials replacing the use of virgin ones. However, the use of food waste as feedstock in biorefineries is still at an early stage of development and studies assessing its economic viability at large scale are lacking in the literature. This paper presents a techno-economic and profitability analysis of four food waste biorefineries that use wastes from tomato, potato, orange, and olive processing as feedstock. The study includes the assessment of potentially available quantities of those waste flows in Europe. Due to the low technology readiness level of this kind of biorefineries, a screening methodology to estimate the investment and manufacturing costs as well as two profitability ratios (the return on investment and the payback time) was adopted. Results show that not all the waste feedstocks have the same potential. The most profitable options are those related to implementing fewer plants, namely concentrating the production and capitalising on economies of scale while being at risk of increasing externalities, e.g. due to logistics of the feedstocks. PMID- 29567597 TI - A randomised field study evaluating the effectiveness of buccal meloxicam and topical local anaesthetic formulations administered singly or in combination at improving welfare of female Merino lambs undergoing surgical mulesing and hot knife tail docking. AB - This study was a field-based behavioural assessment of the pain responses to surgical mulesing modulated by a buccal formulation of meloxicam (Buccalgesic) and a topical local anaesthetic wound dressing (Tri-Solfen). 20 lambs were randomly allocated to each of: 1) Placebo and sham handled (Sham); 2) Placebo and mulesing (Mules); 3) Buccalgesic and mulesing (Mules+B); 4) Tri-Solfen and mulesing (Mules+T); 5) Placebo, Tri-Solfen and mulesing (Mules+T+P); 6) Buccalgesic, Tri-Solfen and mulesing (Mules+T+B). Lamb behaviour was observed by scan sampling every 15 min for 6 h post mulesing then for 1.5 h daily over the subsequent 10 days. Wound score, wound sensitivity and body weight were recorded on day 4, 7 and 10. On the day of mulesing, abnormal behaviours were reduced for all groups that received the analgesic drugs compared to the Mules group (P < 0.05). Tri-Solfen reduced expression of abnormal behaviours in the first 4 h; Buccalgesic reduced expression of abnormal behaviours between 2 and 6 h; and combination treatment reduced expression of abnormal behaviours over the entire observation period. On the subsequent two days, the drug combination resulted in fewer abnormal postures than Tri-Solfen alone. The drug combination tended to result in lower pain sensitivity (965.3 g tolerated) than either Mules+T+P (828.8 g), or Mules+B (791.2 g) on day 7 (P < 0.05). Use of Tri-Solfen and Buccalgesic singly or in combination improved the welfare of lambs undergoing surgical mulesing. The residual effect of pain and discomfort caused by mulesing, were evident despite provision of analgesic drugs. PMID- 29567598 TI - The influence of probiotic supplementation in broiler chickens on population and carcass contamination with Campylobacter spp. - Field study. AB - Campylobacter spp. is a food-borne pathogen occurring all over the world. According to European Food Safety Authority, in Europe, in 2015 the number of recorded and confirmed cases of Campylobacter spp. infections in humans has reached approximately 230,000. Poultry and poultry meat are considered to be the main sources of human infection, which triggers the discussion about the possibility of imposing obligatory control of Campylobacter spp. population at the level of primary poultry production. Recently, the use of probiotics in poultry is considered as a very promising alternative that could reduce infection rate in broiler chickens with Campylobacter spp. Although, there were some approaches made in vivo, up to date, there were no studies that would evaluate those issues under field conditions. A study was carried out in order to determine the feasibility of reducing infection rate in broiler chickens with Campylobacter spp. raised at a commercial farm, by the addition of multispecies probiotic (Lavipan, JHJ, Poland) that composed of Lactococcus lactis, Carnobacterium divergens, Lactobacillus casei, Lactobacillus plantarum and Saccharomyces cerevisae to the feed. Results of our study indicate that probiotic (Lavipan) added to a feed for broiler chickens was capable to reduce the extent of Campylobacter spp. invasion in the gastrointestinal tract of birds and, resultantly, to diminish contamination level in bird environment, which eventually contributed to the improved hygienic parameters of analyzed poultry carcasses. Additionally, this probiotic displayed promising immunomodulatory properties that may improve the effectiveness of the specific prophylaxis program applied in a flock of broiler chickens. PMID- 29567599 TI - Vitamin C-linker-conjugated tripeptide AHK stimulates BMP-2-induced osteogenic differentiation of mouse myoblast C2C12 cells. AB - Vitamin C-linker-conjugated Ala-His-Lys tripeptide (Vit C-AHK) is a derivative of Vitamin C-conjugated tripeptides, which were originally developed as a component of a product for collagen synthesis enhancement or human dermal fibroblast growth. Here, we investigated the effect of Vit C-AHK on bone morphogenetic protein (BMP)-2-induced osteoblast differentiation in a cell culture model. Vit C AHK enhanced proliferation of C2C12 cells and induction of BMP-2-induced alkaline phosphatase, a typical marker of osteoblast differentiation. Vit C-AHK also stimulated the phosphorylation and translocation of Smad1/5/8 to the nucleus and phosphorylation of mitogen-activated protein kinases (MAPKs) including ERK1/2 and p38. In addition, Vit C-AHK enhanced the BMP-2-induced mRNA expression of osteoblast differentiation-related genes such as ALP, BMP-2, Osteocalcin, and Runx2. Our results suggest that Vit C-AHK exerts an enhancing effect on osteoblast proliferation and differentiation through activation of Smad1/5/8 and MAPK ERK1/2 and p38 signaling and without significant cytotoxicity. These results provide important data for the development of peptide-based bone-regenerative agents and treatment of bone-related disorders. PMID- 29567600 TI - Electron-deficient tripodal amide based receptor: An exclusive turn-on fluorescent and colorimetric chemo sensor for cyanide ion. AB - Here in, we have designed, synthesized and isolated sensor L, as an exclusive selective turn-on fluorescent chemo sensor for cyanide ion. The acetonitrile solution contains L with tetrabutyl ammonium cyanide, results sudden color change from colorless to yellowish-brown. Chemosensor L produced a strong fluorescence response with an enhancement of very high fluorescence intensity while addition of CN- ion and the strength of the chemosensor L towards cyanide binding is found to be 3.9813*104M-1. In order to use this sensor in practical application, we also prepared a cassette which is fabricated with sensor L and we succeeded to sense cyanide ion. PMID- 29567601 TI - Simultaneous determination of rosuvastatin and propranolol in their binary mixture by synchronous spectrofluorimetry. AB - Simultaneous determination of rosuvastatin calcium and propranolol hydrochloride using the first derivative synchronous spectrofluorimetry was described. This method involves measuring the synchronous fluorescence of both drugs in ethanol using, ? lambda = 60 nm then the first derivative was recorded and the peak amplitudes were measured at 350 and 374 nm for rosuvastatin calcium and propranolol hydrochloride, respectively. Under the optimum conditions, the linear ranges of rosuvastatin calcium and propranolol hydrochloride were 0.2-2 MUg/mL and 0.1-1 MUg/mL, respectively. The method was used for quantitative analysis of the drugs in raw materials and pharmaceutical dosage form. The validity of the proposed method was assessed according to an international conference on harmonization (ICH) guidelines. PMID- 29567602 TI - Cobalt and cobalt oxides N-codoped porous carbon derived from metal-organic framework as bifunctional catalyst for oxygen reduction and oxygen evolution reactions. AB - Metal-organic framework (MOF)-derived transition metal/metal oxide-carbon hybrids are promising cost-effective electrocatalysts to replace noble metal catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, Co@CoO@Co3O4-N/C was prepared by two-step thermal treatment of Co-MOF ([Co(INA)2].0.5EtOH) (INA: isonicotinic acid). Firstly, Co-MOF, as precursor, was pyrolyzed at different temperatures in N2 atmosphere to obtain Co-N/C-T (T = 700, 800, 900 degrees C) materials among which Co-N/C-800 shows remarkably high ORR activity. After oxidation treatment, Co-N/C-800 is transformed into Co@CoO@Co3O4 N/C which exhibits enhanced electrocatalytic activities for both ORR and OER. The as-obtained Co@CoO@Co3O4-N/C has more positive onset potential (-0.136 V vs. Ag/AgCl) and higher limit current density (4.9 mA cm-2) than Co-N/C-800 (-0.143 V vs. Ag/AgCl and 3.9 mA cm-2), as well as better tolerance to methanol and stability (80.0%) than those of Pt/C (63.2%) for ORR. Co@CoO@Co3O4-N/C also displays outstanding OER performances, with lower overpotential (450 mV) than that of Co-N/C-800 (492 mV) at a current density of 10 mA cm-2. The excellent electrochemical performance of Co@CoO@Co3O4-N/C can be ascribed to uniformly dispersed Co-Nx active sites, strong synergistic effects between N-doped carbon support and Co@CoO@Co3O4 as well as ordered mesoporous structure, boosting mass transfer and accelerating electrocatalytic reaction. PMID- 29567603 TI - Performance of magnetic graphene oxide/diethylenetriaminepentaacetic acid nanocomposite for the tetracycline and ciprofloxacin adsorption in single and binary systems. AB - Adsorption of tetracycline (TC) and ciprofloxacin (CIP) in single and binary systems by diethylenetriaminepentaacetic acid-functionalized magnetic graphene oxide (DDMGO) was explored. DDMGO were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and zeta potential measurements. The adsorption kinetics and equilibrium data of single antibiotic were well fitted by pseudo-second-order and Freundlich isotherm models, respectively. Negative DeltaGo values hinted the spontaneous nature of TC and CIP sorption. Moreover, the DeltaHo was positive for TC removal and negative for CIP removal, indicating that TC adsorption was endothermic and CIP adsorption was exothermic. Various experimental conditions (pH, ionic strength and foreign ions) presented an important influence on TC and CIP removal. In binary systems, TC sorption onto DDMGO exhibited stronger inhibition effect by the coexisting competitive antibiotics than that for CIP. The reusability experiment revealed that the DDMGO had an excellent regeneration performance in single and binary systems. TC and CIP removal mechanism on DDMGO was mainly dependent on pi-pi interaction, hydrogen bonds and amidation reaction. Besides, TC and CIP uptake could also be explained by cation-pi and electrostatic interaction, respectively. These findings showed that DDMGO was an efficient and reusable adsorbent for antibiotics elimination. PMID- 29567604 TI - Design of reduced graphene oxide decorated with DOPO-phosphanomidate for enhanced fire safety of epoxy resin. AB - A facile approach was developed to simultaneously functionalize and reduce graphene oxide (GO) with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO)-phosphonamidate. To achieve stable dispersion and effective stress transfer, graphene was functionalized by polyethyleneimine (PEI). To improve the fire resistance of bare graphene, DOPO was grafted on the surface of PEI-reduced graphene oxide (PEI-rGO) to obtain the grafting of DOPO-phosphonamidate on the graphene. A morphological study indicated that, due to the good interfacial interaction between the functionalized graphene and epoxy (EP), functionalized reduced graphene oxide (f-rGO) was well-dispersed in the host polymer. Incorporation of 3.0 wt% f-rGO led to the increased char yields of the EP. Moreover, the storage modulus and glass transition temperature were improved, respectively. The evaluation of combustion behavior demonstrated that the peak heat release rate and total heat release of f-rGO/EP were reduced by 31% and 34.3%, respectively, compared to those of neat EP. This dramatically reduced fire hazards were mainly attributed to the synergistic effect of f-RGO. On one hand, DOPO-phosphonamidate on the surface of GO promoted flame inhibition in the gas phase while protecting the rGO against fire. On the other hand, the adsorption and barrier effect of rGO inhibited the heat and gas release, respectively, promoting the formation of graphitized carbons. PMID- 29567605 TI - Sodium dodecyl sulfate intercalated and acrylamide anchored layered double hydroxides: A multifunctional adsorbent for highly efficient removal of Congo red. AB - In this study, a novel adsorbent was designed and synthesized via intercalation of sodium dodecyl sulfate (SDS) in the interlayer, and subsequent grafting of acrylamide (AM) on the layer of layered double hydroxides (LDH) (named as AM/SDS LDH), and applied for congo red (CR) removal. The morphological structure, wettability and physicochemical properties of the adsorbents were thoroughly characterized using SEM, EDS, N2-adsorption/desorption isotherm, static contact angle, XRD and FTIR. Results elucidated that SDS and AM were successfully introduced into the interlayer and onto the layer of LDH, respectively. Adsorption experimental results suggested that the maximum adsorption capacities of CR on SDS-LDH and AM/SDS-LDH at pH 5.0 and 293 K were 714.29 and 1118.78 mg/g, respectively, which were much higher than that of CR on LDH (588.24 mg/g). Based on the BET, XRD and FTIR analysis, the higher adsorption capacity of AM/SDS-LDH was mainly attributed to high surface area, large basal spacing as well as the abundant NH2 groups. The experimental data can be well fitted by pseudo-second order kinetic and Langmuir isotherm models. Thermodynamic parameters indicated the adsorption process was favorable under the higher temperature condition. The synergistic effect existed during the adsorption process of CR onto AM/SDS-LDH, including the electrostatic interactions, anion exchange and hydrophobic hydrophobic interactions. Overall, this study provided a strategy for design and fabrication of highly efficient adsorbents. PMID- 29567606 TI - Formation of block-copolymer-templated mesoporous silica. AB - In situ attenuated total reflectance Fourier transform infrared spectroscopy is used to monitor the chemical evolution of the mesoporous silica SBA-15 from hydrolysis of the silica precursor to final silica condensation after the particle formation. Two silica precursors, tetraethyl orthosilicate (TEOS) or sodium metasilicate (SMS) were used, and the effects of additive (heptane and NH4F) concentrations were studied. Five formation stages are identified when TEOS is used as the precursor. The fourth stage correlates with the appearance and evolution of diffraction peaks recorded using in situ small angle X-ray diffraction. Details of the formed silica matrix are observed, e.g. the ratio between six-fold cyclic silica rings and linear bonding increases with the NH4F concentration. The TEOS hydrolysis time is independent of the NH4F concentration for small amounts of heptane, but is affected by the size of the emulsion droplets when the heptane amount increases. Polymerization and condensation rates of both silica precursors are affected by the salt concentration. Materials synthesized using SMS form significantly faster compared to TEOS-materials due to the pre-hydrolysis of the precursor. The study provides detailed insights into how the composition of the synthesis solution affects the chemical evolution and micellar aggregation during formation of mesoporous silica. PMID- 29567607 TI - Facile construction of terpridine-based metallo-polymers in hydrogels, crystals and solutions directed by metal ions. AB - Driven by tunable metal-ligand interactions, a polydentate ligand TC containing terpyridine and carboxylic acid units was developed to construct metallo-polymers that showed multiple aggregation modes with controlled macroscopic properties. In the presence of different kind of Zn2+ ions or NaOH, TC could form metallo polymers via pi-pi stacking and metal-ligand interaction that further trapped water molecules, resulting in hydrogels and crystals. Moreover, these TC/Zn2+ hydrogels could transform to soluble and fluorescent aggregates in the presence of NaOH due to the formation of binuclear metallo-polymers with enhanced ICT emission. The metal-ligand interactions tuned by different metal salts in gels, crystals, and sols were also studied and illustrated in detail, it was also proved that water was an essential linker for constructing Na+-based metallo polymers from the TC/NaOH crystal data. This work demonstrated the engineered coordination pathways in generating controllable hydrogels and metallo-polymers for the first time, which led to novel approach for facilely constructing a number of hydrogels with tailorable macroscopic properties. PMID- 29567608 TI - Evaluating tetracycline degradation pathway and intermediate toxicity during the electrochemical oxidation over a Ti/Ti4O7 anode. AB - Tetracycline (TC) is one of the most widely used antibiotics with significant impacts on human health and thus it needs appropriate approaches for its removal. In the present study, we evaluated the performance and complete pathway of the TC electrochemical oxidation on a Ti/Ti4O7 anode prepared by plasma spraying. Morphological data and composition analysis indicated a compact coating layer on the anode, which had the characteristic peaks of Ti4O7 as active constituent. The TC electrochemical oxidation on the Ti/Ti4O7 anode followed a pseudo-first-order kinetics, and the TC removal efficiency reached 95.8% in 40 min. The influential factors on TC decay kinetics included current density, anode-cathode distance and initial TC concentration. This anode also had high durability and the TC removal efficiency was maintained over 95% after five times reuse. For the first time, we unraveled the complete pathway of the TC electrochemical oxidation using high performance liquid chromatograph (HPLC) and gas chromatograph (GC) coupled with mass spectrometer (MS). .OH radicals produced from electrochemical oxidation attack the double bond, phenolic group and amine group of TC, forming a primary intermediate (m/z = 461), secondary intermediates (m/z = 432, 477 and 509) and tertiary intermediates (m/z = 480, 448 and 525). The latter were further oxidized to the key downstream intermediate (m/z = 496), followed by further downstream intermediates (m/z = 451, 412, 396, 367, 351, 298 and 253) and eventually short chain carboxylic acids. We also evaluated the toxicity change during the electrochemical oxidation process with bioluminescent bacteria. The bioluminescence inhibition ratio peaked at 10 min (55.41%), likely owing to the high toxicity of intermediates with m/z = 461, 432 and 477 as obtained from quantitative structure activity relationship (QSAR) analysis. The bioluminescence inhibition ratio eventually decreased to 16.78% in 40 min due to further transformation of TC and intermediates. By comprehensively analyzing the influential factors and complete degradation pathway of TC electrochemical oxidation on the Ti/Ti4O7 anode, our research provides deeper insights into the risk assessment of intermediates and their toxicity, assigning new perspectives for practical electrochemical oxidation to effectively eliminate the amount and toxicity of TC and other antibiotics in wastewater.

AB - We examined the vaginal opening day, ovary and uterus organ coefficient, reproductive hormone levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH), mRNA and protein expression levels of kiss-1, hypothalamus gonadotrophin releasing hormone 1 (GnRH1), organic cation transporters 2 (Oct2) and transcription termination factor 1 (Ttf1) in different pubertal ages [late lactation (18 days), pre-puberty (21-22 days), puberty (23-27 days; with respect to vaginal opening) and maturity (65 days)] of offspring females, to evaluate the effect of arsenic (As) on puberty initiation after maternal exposure to As at different concentration [0, 0.15, 1.5 and 15 mg/L As(III)] during gestational period. The results showed that the vaginal opening time was significantly advanced in utero in mice exposed to As compared to the control. The hormone level of LH was significantly increased in the mice treated with 15 mg/L of As(III) at puberty compared to the control. During puberty, the mRNA expression levels of kiss-1, GnRH1, Oct2 and Ttf1 in the hypothalamus were significantly increased in the group treated with 15 mg/L of As(III) compared to the control. The protein expressions of Kisspeptin, GnRH1, Oct2 and Ttf1 in the hypothalamus were significantly increased in the pubertal females, while Oct2 and Ttf1 expression levels were significantly decreased in the matured females compared to the control, which is in line with the transcriptional changes of related mRNA expressions. In brief, this study demonstrated that maternal exposure to As during gestational period could result in early onset of puberty in offspring females. PMID- 29567610 TI - Removal of rhodamine 6G with different types of clay minerals. AB - With an increased use of color dye in textile industries and elevated fabrics output, more scientific studies and technology developments are needed to effectively treat wastewater containing dyes. However, better understanding of the interactions between dyes and suspended solids is a necessity to advance such developments. In this study the interactions between rhodamine 6G (R6G), a cationic dye, and different types of clays minerals, commonly found in the wastewater sludge, were elucidated. The uptake of R6G on the clay minerals was attributed to cation exchange on the external surfaces of non-swelling clays, and at both external and interlayer spaces for swelling clays. In the interlayer of montmorillonite, the R6G molecules form monolayer and bilayer configurations under low and high uptake levels. The significant amounts of R6G uptake indicate that clay minerals are good sorbents for the removal of cationic dyes from water. And the R6G could be readily removed in wastewater treatment by adding small amount of clays and flocculated the clays out. PMID- 29567611 TI - Ecological risks posed by ammonia nitrogen (AN) and un-ionized ammonia (NH3) in seven major river systems of China. AB - Previous studies showed that continuous exposure to ammonia nitrogen (AN) contributed to regional losses of benthic invertebrate diversity in China. Yet, the overall ecological risk of AN to aquatic organisms in major riverine systems of China has not been appropriately studied. Our research then investigated temporal (seasonally/yearly) and spatial distributions of AN and un-ionized ammonia (NH3) in major Chinese river basins using historic data generated between 2007 and 2014, and developed risk assessment criteria. Our results showed that the highest average AN concentrations occurred during winter (0.82-2.76 mg/L) and the lowest during summer (0.36-0.78 mg/L). NH3 exhibited the opposite trend with the highest average concentrations mostly observed during spring (15.13-92.84 MUg/L) and the lowest concentrations mainly during winter (10.53-45.43 MUg/L). Both AN and NH3 concentrations steadily increased and reached maximum levels in 2008 (AN: 1.22 mg/L and NH3: 50.65 MUg/L), and then decreased. Temporal trends showed that the Yellow, Hai, and Huai river basins had the highest AN and NH3 concentrations. Subsequently, conventional (hazard quotients) and probabilistic (joint probability curves) methods were applied to assess the hazards and risks posed by AN and NH3. The results showed that the probability of exceeding the acute toxicity threshold for 5% of species (exposed to AN or NH3) was less than 13.3% and gradually decreased over time. To protect aquatic organisms, an acute criterion of 51.4 MUg NH3/L and a chronic criterion of 1.14 mg AN/L at pH = 7.5, 20 degrees C were developed and are recommended for future risk assessment studies. PMID- 29567612 TI - Is the aquatic toxicity of cationic polyelectrolytes predictable from selected physical properties? AB - Cationic acrylamide-based polyelectrolytes (cPAM) are widely used in industry. They can be designed for optimal performance in a specific application, but this opportunity means the environmental safety of all different alternatives needs to be addressed. Both the inclusion of environmental toxicity as a design variable and the establishment of relationships between structure and ecotoxicity are thus current challenges. The aim of this study was to assess whether structural variables such as molecular weight, charge density and the integrative intrinsic viscosity parameter can be used to predict the environmental safety of cPAMs, as well as if these relationships are stable when the biological models change. Five cPAMs comprising molecular weight and charge density gradients were tested against bacteria, microalgae, macrophytes and daphnids. While correlations were found between physical properties of cPAMs as expected, no clear ecotoxicity patterns could be identified. All cPAMs can be classified as harmful to aquatic life on the basis of the responses elicited in the most sensitive organisms, microalgae and daphnids. Unicellular bacteria were the least sensitive eco receptors possibly due to cell wall structure or the protective effect of the ionic strength of the test medium. The macrophytes were also tolerant to cPAMs exposure, which may be related to exposure avoidance mechanisms. The order of toxicity of cPAMs depended on the test organism, preventing the establishment of stable structure-ecotoxicity relationships. Therefore, the study leads to the overall generalist recommendation of relying on the most sensitively responding test organisms when developing new (eco)safe-by-design cPAMs. PMID- 29567613 TI - Ecological and health risk assessment of potentially toxic elements in the major rivers of Pakistan: General population vs. Fishermen. AB - Large amounts of potentially toxic elements (PTEs) have, and continue to be, released into the freshwater ecosystems of Pakistan. However, there is limited information available on the ecological risk of PTEs from sediments and fish consumption, for both the general population and fishermen, at the national scale in Pakistan. In this study, water, sediments and fish samples were collected from major rivers (Chenab, Upper Indus, Lower Indus and Kabul) across Pakistan and analyzed through Inductively Coupled Plasma Mass Spectrometer (ICP-MS), Inductively Coupled Plasma Atomic Emission Spectroscopy ICP-AES and Atomic Fluorescence Spectrometry (AFS), respectively. Ecological risk analysis of sediments revealed that Cd posed a high ecological risk in the Upper Indus and Chenab, a considerable risk in the Lower Indus, and moderate risk in the Kabul. The target hazard quotient of As through fish tissue consumption exceeded safety levels for fishermen at all the rivers, where Cd exceeded at Upper Indus and Chenab, and Pb for Chenab fishermen only. For the general population, PTE ingestion through fish tissues was within the safety limits at all rivers. Meanwhile, the total target hazard quotient in all three rivers exceeded the safety limit, representing a high risk for the fishermen of Pakistan. The results show that ecological risk and target hazard quotient assessment not only provides valuable information for future research in terms of PTE contamination in the major rivers of Pakistan, but also all the metal pollutants from rivers finally reach to Arabian Sea, therefore might pose a risk to marine ecosystem at national and international scale. PMID- 29567614 TI - Risk of a false decision on conformity of an environmental compartment due to measurement uncertainty of concentrations of two or more pollutants. AB - Risks of false decisions in conformity assessment of an environmental compartment due to measurement uncertainty of concentrations of two or more pollutants are discussed. Even if the assessment of conformity for each pollutant in the compartment is successful, the total probability of a false decision concerning the compartment as a whole might still be significant. A model of the total probability of a false decision, formulated on the base of the law of total probability, is used, for example, for a study of test results of total suspended particulate matter (TSPM) concentration in ambient air near to three independent stone quarries located in Israel, as the sources of the air pollution. Total probabilities of underestimation of TSPM concentration (total risk of the inhabitants) and overestimation (total risk of the stone producers) are evaluated as a combination of the particular risks of air conformity assessment concerning TSPM concentration for each quarry. These probabilities characterize conformity of the TSPM concentration in the region of the quarries as a whole. Core code developed in R programming environment for the calculations is provided. PMID- 29567615 TI - Enumeration of the constitutional isomers of environmentally relevant substituted polycyclic aromatic compounds. AB - Polycyclic aromatic compounds (PACs) are a diverse group of environmentally relevant compounds which can be persistent, bioaccumulative and toxic. The cyclic backbone of PACs can be substituted with halogens or hydrocarbon chains. The amount and positions of these substituents influence their toxicity. For many classes of PACs, substitution creates mixtures containing large numbers of isomers. For example, 209 theoretical isomers of chlorinated biphenyls are possible. Many other classes of environmentally relevant PACs exist where the number of theoretical isomers are unknown. Here, a mathematical approach using molecular symmetry and the binomial coefficient is presented that determines the number of theoretical isomers of PACs. The approach was validated on PACs with known isomer numbers and then applied to PACs with unknown isomer numbers. When the approach was applied to alkylated polycyclic aromatic hydrocarbons, the possible theoretical isomers ranged from 2 for C1 naphthalene up to 19 502 for C6 dibenzo(ah)anthracene. Heterocyclic PACs had similar numbers ranging from 4 isomers for C1 dibenzothiophene to 13 938 for C6 dibenzo[a,i]carbazole. The work presented will aide analytical chemists and ecotoxicologists in their efforts to develop methods to measure these compounds, and in attempting to assess the toxicity and environmental fate of individual isomers. PMID- 29567617 TI - Health related quality of life and its associated factors among community dwelling older people in Sri Lanka: A cross-sectional study. AB - BACKGROUND: Population ageing has become a public health issue as it is associated with increased morbidity, institutionalization and death. These may directly affect health-related quality of life (HRQOL) of older people. PURPOSE: The aim of the study was to investigate HRQOL and its associated factors among community-dwelling older people in Kandy district, Sri Lanka. METHOD: This cross sectional survey involved 1300 older people. The Euro 5D-3L, International Physical Activity Questionnaire, body mass index, handgrip strength were used to measure HRQOL, physical activity and nutritional status of older people respectively. Factors associated with health-related quality of life were identified through complex sample logistic regression analysis. RESULTS: Majority of older people (81.9%) reported poor health-related quality of life. Middle old (aOR: 12.06, 95% CI: 5.76, 25.23), very old (aOR: 174.74, 95% CI: 39.74, 768.38), vegetarian diets (aOR: 2.13, 95% CI: 1.14, 3.96), under-nutrition (aOR: 3.41, 95% CI: 1.65, 7.04) and over-nutrition (aOR: 1.85, 95% CI: 1.04, 3.28) were significantly associated with poor HRQOL. Using dentures (aOR: 0.05, 95% CI: 0.28, 0.90) was found as a protective factor for poor HRQOL. CONCLUSIONS: HRQOL was poor among community-dwelling older people in Kandy district. Nutrition related factors need to be further investigated to improve HRQOL among older people. PMID- 29567616 TI - Age-dependent regulation of antioxidant genes by p38alpha MAPK in the liver. AB - p38alpha is a redox sensitive MAPK activated by pro-inflammatory cytokines and environmental, genotoxic and endoplasmic reticulum stresses. The aim of this work was to assess whether p38alpha controls the antioxidant defense in the liver, and if so, to elucidate the mechanism(s) involved and the age-related changes. For this purpose, we used liver-specific p38alpha-deficient mice at two different ages: young-mice (4 months-old) and old-mice (24 months-old). The liver of young p38alpha knock-out mice exhibited a decrease in GSH levels and an increase in GSSG/GSH ratio and malondialdehyde levels. However, old mice deficient in p38alpha had higher hepatic GSH levels and lower GSSG/GSH ratio than young p38alpha knock-out mice. Liver-specific p38alpha deficiency triggered a dramatic down-regulation of the mRNAs of the key antioxidant enzymes glutamate cysteine ligase, superoxide dismutase 1, superoxide dismutase 2, and catalase in young mice, which seems mediated by the lack of p65 recruitment to their promoters. Nrf 2 nuclear levels did not change significantly in the liver of young mice upon p38alpha deficiency, but nuclear levels of phospho-p65 and PGC-1alpha decreased in these mice. p38alpha-dependent activation of NF-kappaB seems to occur through classical IkappaB Kinase and via ribosomal S6 kinase1 and AKT in young mice. However, unexpectedly the long-term deficiency in p38alpha triggers a compensatory up-regulation of antioxidant enzymes via NF-kappaB activation and recruitment of p65 to their promoters. In conclusion, p38alpha MAPK maintains the expression of antioxidant genes in liver of young animals via NF-kappaBeta under basal conditions, whereas its long-term deficiency triggers compensatory up regulation of antioxidant enzymes through NF-kappaBeta. PMID- 29567618 TI - Subjective and objective sleep quality in elderly individuals: The role of psychogeriatric evaluation. AB - Aging affects sleep and sleep problems are common in older individuals. However, the relationship between objective and subjective tools for analysing sleep and psycho-geriatric variables have not been tested in institutionalised older individuals. This work analyses sleep quality by using actigraphy as an objective tool and validates the Athens and Oviedo sleep questionnaires in octogenarian elderly individuals as subjective scales of sleep perception. All patients wore an actigraph device for one week and then completed the Athens and Oviedo clinical sleep-evaluation questionnaires. Morning cortisol levels in blood plasma and saliva samples were also measured to assess the association between objective and reported sleep patterns. Age, gender, and psycho-geriatric evaluations, including Barthel, Tinetti, and Mini-Mental scale measurements were analysed as variables with the potential to confound the strength of any such associations. There was a significant inverse correlation between the number of awakenings and the time spent awake during night assessed by actigraphy and the total Oviedo questionnaire score, but no significant associations for the other parameters. The blood cortisol concentration appears to be a marker of insomnia related to sleep times of less than four hours and diagnosis of insomnia based on Athens scale and thus, represents a potential marker for sleep interventions. PMID- 29567619 TI - Tweeting weight loss: A comparison of #thinspiration and #fitspiration communities on Twitter. AB - Thinspiration and fitspiration represent contemporary online trends designed to inspire viewers towards the thin ideal or towards health and fitness respectively. The aim of the present study was to compare thinspiration and fitspiration communities on Twitter. A total of 3289 English-language tweets with hashtags related to thinspiration (n = 1181) and fitspiration (n = 2578) were collected over a two-week period. Network analysis showed minimal overlap between the communities on Twitter, with the thinspiration community more closely connected and having greater information flow than the fitspiration community. Frequency counts and sentiment analysis showed that although the tweets from both types of accounts focused on appearance and weight loss, fitspiration tweets were significantly more positive in sentiment. It was concluded that the thinspiration tweeters, unlike the fitspiration tweeters, represent a genuine on-line community on Twitter. Such a community of support may have negative consequences for collective body image and disordered eating identity. PMID- 29567620 TI - Social stress response in adolescents with bipolar disorder. AB - OBJECTIVE: Theoretical models posit that stressors contribute to the onset and maintenance of bipolar disorder in adolescence through disruptions in stress physiology, but physiological response to stressors has not been evaluated in adolescents with bipolar illness. The present study tests the hypothesis that adolescents with bipolar disorder will have greater reactivity to a laboratory social stress task than healthy adolescents. METHOD: Adolescents with bipolar illness (n = 27) and healthy adolescents (n = 28) completed a modified version of the Trier Social Stress Task. Stress response was assessed using high frequency heart rate variability (HF-HRV), heart rate (HR), mean arterial blood pressure (MAP), salivary cortisol, and subjective stress. Multilevel models were used to test for group differences in resting-state physiology, and stress reactivity and recovery. RESULTS: Adolescents with bipolar disorder had greater reactivity in HF HRV (z = 3.32), but blunted reactivity in MAP (z = -3.08) and cortisol (z = 2.60), during the stressor compared to healthy adolescents. They also had lower resting HF-HRV (z = -3.49) and cortisol (z = -2.86), and higher resting HR (z = 3.56), than healthy adolescents. CONCLUSIONS: These results indicate that bipolar disorder is associated with disruptions in autonomic and endocrine response to stress during adolescence, including greater HF-HRV reactivity. Further research should evaluate whether these individual differences in stress physiology precede and predict the onset of mood episodes. PMID- 29567622 TI - Th9 lymphocytes and functions of interleukin 9 with the focus on IBD pathology. AB - The work presents the newest knowledge on a new phenotype of T helper lymphocytes (Th9) and on Interleukin 9 (IL-9). Processes leading to transformation of naive T lymphocyte into Th9 lymphocytes are presented, including the role of IL-4 and TGFbeta signaling. Involvement of transcription factor network in production of IL-9 is described. Other cells capable of expressing IL-9 and secreting IL-9 are portrayed. Diversity of IL-9 effects caused by activation of IL-9 receptors on various types of cells is presented. Principal effects of the activation of IL-9 receptor on T-cells seem to be antiapoptotic and stimulatory which leads to enhanced defense against parasitic infection and cancer development but, from the other side, it perpetuate chronic inflammation in autoimmune diseases and allergic processes. In the last years the role of IL-9 in autoimmune diseases such as rheumatic diseases and inflammatory bowel disease gained importance since the increased expression of this cytokine has been observed in animal models of intestinal inflammation and in groups of patients with ulcerative colitis. It was also noted that neutralization of IL-9 in animal models of ulcerative colitis leads to amelioration of inflammatory process, what could have significance in the treatment of this disease in humans in the future. PMID- 29567623 TI - Post-polyploid diploidization and diversification through dysploid changes. AB - Whole-genome duplications are widespread across land plant phylogenies and particularly frequent in ferns and angiosperms. Genome duplications spurred the evolution of key innovations associated with diversification in many angiosperm clades and lineages. Such diversifications are not initiated by genome doubling per se. Rather, differentiation of the primary polyploid populations through a range of processes results in post-polyploid genome diploidization. Structural diploidization gradually reverts the polyploid genome to one functionally diploid like through chromosomal rearrangements which frequently result in dysploid changes. Dysploidies may lead to reproductive isolation among post-polyploid offspring and significantly contribute to speciation and cladogenetic events. PMID- 29567621 TI - Diet matters: Glucocorticoid-related neuroadaptations associated with calorie intake in female rhesus monkeys. AB - Exposure to psychosocial stressors increases consumption of palatable, calorically dense diets (CDD) and the risk for obesity, especially in females. While consumption of an obesogenic diet and chronic stress have both been shown to decrease dopamine 2 receptor (D2R) binding and alter functional connectivity (FC) within the prefrontal cortex (PFC) and the nucleus accumbens (NAcc), it remains uncertain how social experience and dietary environment interact to affect reward pathways critical for the regulation of motivated behavior. Using positron emission tomography (PET) and resting state functional connectivity magnetic resonance neuroimaging (rs-fMRI), in female rhesus monkeys maintained in a low calorie chow (n = 18) or a dietary choice condition (chow and a CDD; n = 16) for 12 months, the current study tested the overarching hypothesis that the adverse social experience resulting from subordinate social status would interact with consumption of an obesogenic diet to increase caloric intake that would be predicted by greater cortisol, lower prefrontal D2R binding potential (D2R-BP) and lower PFC-NAcc FC. Results showed that the consequences of adverse social experience imposed by chronic social subordination vary significantly depending on the dietary environment and are associated with alterations in prefrontal D2R BP and FC in NAcc-PFC sub-regions that predict differences in caloric intake, body weight gain, and fat accumulation. Higher levels of cortisol in the chow only condition were associated with mild inappetence, as well as increased orbitofrontal (OFC) D2R-BP and greater FC between the NAcc and the dorsolateral PFC (dlPFC) and ventromedial PFC (vmPFC). However, increased cortisol release in females in the dietary choice condition was associated with reduced prefrontal D2R-BP, and opposite FC between the NAcc and the vmPFC and dlPFC observed in the chow-only females. Importantly, the degree of these glucocorticoid-related neuroadaptations predicted significantly more total calorie intake as well as more consumption of the CDD for females having a dietary choice, but had no relation to calorie intake in the chow-only condition. Overall, the current findings suggest that dietary environment modifies the consequences of adverse social experience on reward pathways and appetite regulation and, in an obesogenic dietary environment, may reflect impaired cognitive control of food intake. PMID- 29567624 TI - Functional inactivation of the orbitofrontal cortex disrupts context-induced reinstatement of alcohol seeking in rats. AB - BACKGROUND: The high rate of relapse to drug use remains a central challenge to treating drug addiction. In human and rat models of addiction, environmental stimuli in contexts associated with previous drug use can provoke a relapse of drug seeking. Pre-clinical studies have used the ABA renewal procedure to study context-induced reinstatement of drug seeking. In the current study, we studied the role of the orbitofrontal cortex (OFC) in context-induced reinstatement to alcohol. METHODS: We trained male and female rats to self-administer alcohol in context A, extinguished drug-reinforced responding in a distinct context B, and assessed context-induced reinstatement in context A or B (control group). Next, we determined the effect of context-induced renewal of alcohol-seeking behavior on the expression of Fos (a neuronal activity marker) in the OFC. Finally, we determined the effect of reversible inactivation by GABAa and GABAb receptor agonists (i.e., muscimol and baclofen, respectively) in the OFC. RESULTS AND CONCLUSIONS: There were no differences between male and female rats in context induced reinstatement of alcohol-seeking behavior. Re-exposure to Context A, but not Context B, reinstated alcohol-seeking behavior and increased expression of the neural activity marker Fos in the OFC. Reversible inactivation of the OFC with muscimol and baclofen attenuated context-induced reinstatement. Our data indicated that the OFC mediates context-induced reinstatement of alcohol-seeking behavior. PMID- 29567625 TI - The dual-process model in young adults with a consistent binge drinking trajectory into adulthood. AB - BACKGROUND: Binge Drinking (BD) generally declines once students have left university. However, many individuals continue to partake in BD into adulthood, constituting a scarcely investigated high-risk group towards whom interventions should be prioritized. Following the dual-process model, we examined the relationship between BD and both the reflective system (executive functions) and the affective system (alcohol bias) in young adults with a consistent BD trajectory. We considered impulsivity as a moderator in the relationship between BD and alcohol bias. METHODS: A cohort of 63 (31?) young adults were followed for eleven years (18-29 years old). In the last assessment, participants, with high and low drinking trajectories underwent neuropsychological assessment of executive functions (working memory [SOPT], cognitive flexibility [TMT -Verbal Fluency], inhibition [Stroop]) and alcohol bias (Addiction Stroop). The Barratt Impulsivity Scale measured impulsivity. Generalized linear mixed models and regression-based moderation models were applied. RESULTS: BD was associated with weak inhibitory control, poor working memory and greater alcohol bias moderated by non-planning impulsivity. At moderate levels of non-planning impulsivity, BD was associated with greater alcohol bias. This association was not found at high levels of impulsivity. These deficits were related to loss of control over drinking and severity of alcohol use. CONCLUSIONS: The imbalance between poor cognitive control and greater alcohol bias may contribute to the persistence of BD into adulthood. The findings highlight the complexities of the dual-process model, with intervention implications. PMID- 29567627 TI - Recurrent pseudotumoral relapses in multiple sclerosis: a case report. AB - OBJECTIVES: Multiple sclerosis (MS) is the most common chronic disabling disease of the central nervous system (CNS) in young adults. It is characterized by the presence of multiple demyelinating inflammatory lesions disseminated in the CNS. Pseudotumoral lesions (PL) are rarely observed in patients with MS. METHODS: These atypical lesions can pose a diagnostic problem, especially when they are present at disease onset. RESULTS: Most MS patients with PLs only have a single episode throughout their disease course, which reflects its low tendency of recurrence. CONCLUSIONS: We report the rare case of a 34-year-old MS patient who suffered from recurrent pseudotumoral episodes during follow-up. PMID- 29567626 TI - Trends in and correlates of medical marijuana use among adults in the United States. AB - BACKGROUND: Trends in and correlates of medical marijuana use are important to inform ongoing clinical, research, policy, and programmatic efforts. This study assessed trends in and correlates of medical marijuana use among U.S. adults. METHODS: We analyzed data from approximately 147,200 U.S. civilians aged 18 or older who participated in the 2013-2015 National Surveys on Drug Use and Health. Descriptive analyses, multivariable logistic regressions, and zero-truncated native binomial regressions were applied. RESULTS: Among U.S. adults, the prevalence of medical marijuana use increased from 1.2% in 2013 to 1.6% in 2015 (p = 0.0007). After adjusting for covariates, adults residing in medical marijuana states (states with legalized medical marijuana use) were 1.3 times more likely to use marijuana medically in 2015 than in 2013 (adjusted odds ratio (AOR) = 1.3, 95% confidence interval (CI) = 1.03-1.61), and adults in nonmedical marijuana states were 1.4 times more likely to report medical marijuana use in 2015 than in 2013 (AOR = 1.4, 95% CI = 1.05-1.90). Among adults who used marijuana exclusively for medical purposes in the past 12 months, trends in 12 month cannabis use disorders, daily or near daily use, and the number of days of marijuana use remained unchanged during 2013-2015. We identified how correlates of medical marijuana use among adults in medical marijuana states differed from their counterparts in nonmedical marijuana states. CONCLUSIONS: Adults were more likely to use marijuana medically in 2015 than in 2013 in both medical and nonmedical marijuana states. Clinicians need to learn about and address evolving patterns of medical marijuana use in patients. PMID- 29567628 TI - Coronary computed tomography angiography and endocardial leads - Image quality in 320-row CT using iterative reconstruction. AB - PURPOSE: To investigate whether the presence of endocardial leads has an impact on image quality in coronary computed tomography angiography (CCTA), when current technique is employed using a 320-row computed tomography and iterative reconstruction. MATERIALS AND METHODS: CCTA was performed in 1641 patients, from these we identified 51 patients (study group) with endocardial leads and 51 matched partners (control group) without endocardial leads. Noise was determined in the ascending aorta and the left ventricle; signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were determined in the left and right coronary artery. Subjective image quality was rated separately for the 15 segments of the coronary arteries by 2 radiologists. RESULTS: Current CCTA technique still shows slight impairment of objective image quality in patients with endocardial leads with inferior SNR in the aorta (median 15.04 versus 16.6; p = 0.004) and inferior SNR in the left/right coronary artery (median 15.3/13.81 versus 16.1/15.41; p = 0.013/0.002). CNR of the left/right coronary artery was also inferior (median 17.4/16.46 versus 19.26/19.24; p = 0.002/<0.001). The subjective image quality was rated significantly inferior only in segment 8 (p = 0.001) compared to the control group. Artifacts by ventricular leads were found in 65% of the patients in segment 8 with non-diagnostic rating in 9 cases (18%). Atrial leads resulted in artifacts predominantly in segment 1 (45%) with non-diagnostic rating in only 2 cases (4%). CONCLUSION: CCTA is feasible with slight restrictions for patients in the presence of implanted cardiac devices when current technique is used. PMID- 29567629 TI - Whole-brain volume alteration and its correlation with anxiety severity in patients with obsessive-compulsive disorder and generalized anxiety disorder. AB - PURPOSE: To evaluate the differential gray matter (GM) and white matter volume alterations between healthy controls and patients with obsessive-compulsive disorder (OCD) and generalized anxiety disorder (GAD) using voxel-based morphometry (VBM). METHOD: Patients with OCD and GAD, and healthy controls underwent MR. RESULTS: Patients with GAD showed significantly decreased GM volume in the medial prefrontal cortex (mPFC) compared with patients with OCD (p < 0.001). The GM volumes of the mPFC in patients with GAD were negatively correlated with Hamilton Anxiety Rating Scales. CONCLUSION: Our findings indicate that the mPFC volume abnormality may be associated with anxiety disorder in patients with GAD rather than OCD. PMID- 29567631 TI - Interventional radiology: Role in the treatment of sarcomas. AB - In bone and soft tissue sarcomas (STS), surgery was to the only local curative treatment, but recently, radiation therapy and interventional radiology has evolved to potentially curative treatment, namely in small size tumours. Indication for local treatment in STS needs validation in multidisciplinary team. Most will agree on local treatment for single metastatic location in a well controlled disease and for no local treatment in a rapidly evolving multi metastatic disease. The challenge is in patients who are in between, for whom benefit of disease control on overall survival should be evaluated. Local treatment has been reported beneficial in some large retrospective series, regardless of the association with chemotherapy in selected patients with oligometastatic disease. Recent technical innovation in image guidance allows to deliver local treatment through needles inserted percutaneously, and image-guided thermal ablation of small tumour is now part of the treatment armamentarium in selected oligometastatic diseases, allowing for local destruction of small tumour. Radiofrequency ablation allows to control small size STS lung metastases in roughly 90% of attempts, thus providing an efficient and low-invasive local control with preservation of organ function. Small size bone deposit can be targeted with the same rate of efficacy when tumours are small. Ablation can be used in the liver when some tumour foci become resistant to systemic therapy, namely in gastrointestinal stromal tumour patients. In addition, interventional radiology can now provide efficient and rapid pain palliation as well as bone reconstruction with the use of cementoplasty and percutaneous osteosynthesis, alongside radiation therapy which has been a long time player for pain palliation in bone metastases.

AB - BACKGROUND: Alveolar rhabdomyosarcomas (ARMSs) can harbour MET and anaplastic lymphoma kinase (ALK) alterations. We prospectively assessed crizotinib in patients with advanced/metastatic ARMS. METHODS: Eligible patients with a central diagnosis of ARMS received oral crizotinib 250 mg twice daily. Patients were attributed to MET/ALK+ or MET/ALK- subcohorts by assessing the presence or absence of the forkhead box O1 (FOXO1; a marker of MET upregulation) and/or ALK gene rearrangement. The primary end-point was the objective response rate (ORR). Secondary end-points included duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), progression-free rate (PFR), overall survival (OS) and safety. FINDINGS: Nineteen of 20 consenting patients had centrally confirmed ARMS. Molecular assessment revealed rearrangement of FOXO1 in 17 tumours and ALK in none. Thirteen eligible patients were treated, but only eight were evaluable for the primary end-point because of the observed aggressiveness of the disease. Among seven evaluable MET+/ALK- patients, only one achieved a confirmed partial response (ORR: 14.3%; 95% confidence interval [CI]: 0.3-57.8) with a DOR of 52 d. Further MET+/ALK- efficacy end-points were DCR: 14.3% (95% CI: 0.3-57.8), median PFS: 1.3 months (95% CI: 0.5-1.5) and median OS: 5.6 months (95% CI: 0.7-7.0). The remaining MET+/ALK- and MET-/ALK- patients had early progression as best response. Common treatment-related adverse events were fatigue (5/13 [38.5%]), nausea (4/13 [30.8%]), anorexia (4/13 [30.8%]), vomiting (2/13 [15.4%]) and constipation (2/13 [15.4%]). All 13 treated patients died early because of progressive disease. INTERPRETATION: Crizotinib is well tolerated but lacks clinically meaningful activity as a single agent in patients with advanced metastatic ARMS. Assessing single agents in aggressive, chemotherapy-refractory ARMS is challenging, and future trials should explore established chemotherapy +/- investigational compounds in earlier lines of treatment. CLINICAL TRIAL NUMBER: EORTC 90101, ClinicalTrials.gov NCT01524926. PMID- 29567630 TI - Anthracycline-induced cardiotoxicity: A multicenter randomised trial comparing two strategies for guiding prevention with enalapril: The International CardioOncology Society-one trial. AB - BACKGROUND: Troponin changes over time have been suggested to allow for an early diagnosis of cardiac injury ensuing cancer chemotherapy; cancer patients with troponin elevation may benefit of therapy with enalapril. It is unknown whether a preventive treatment with enalapril may further increase the benefit. METHODS: The International CardioOncology Society-one trial (ICOS-ONE) was a controlled, open-label trial conducted in 21 Italian hospitals. Patients were randomly assigned to two strategies: enalapril in all patients started before chemotherapy (CT; 'prevention' arm), and enalapril started only in patients with an increase in troponin during or after CT ('troponin-triggered' arm). Troponin was assayed locally in 2596 blood samples, before and after each anthracycline-containing CT cycle and at each study visit; electrocardiogram and echocardiogram were done at baseline, and at 1, 3, 6 and 12-month follow-up. Primary outcome was the incidence of troponin elevation above the threshold. FINDINGS: Of the 273 patients, 88% were women, mean age 51 +/- 12 years. The majority (76%) had breast cancer, 3% had a history of hypertension and 4% were diabetic. Epirubicin and doxorubicin were most commonly prescribed, with median cumulative doses of 360 [270-360] and 240 [240-240] mg/m2, respectively. The incidence of troponin elevation was 23% in the prevention and 26% in the troponin-triggered group (p = 0.50). Three patients (1.1%) -two in the prevention, one in the troponin triggered group-developed cardiotoxicity, defined as 10% point reduction of LV ejection fraction, with values lower than 50%. INTERPRETATION: Low cumulative doses of anthracyclines in adult patients with low cardiovascular risk can raise troponins, without differences between the two strategies of giving enalapril. Considering a benefit of enalapril in the prevention of LV dysfunction, a troponin-triggered strategy may be more convenient. PMID- 29567633 TI - Web 2.0 Tools in the Prevention of Curable Sexually Transmitted Diseases: Scoping Review. AB - BACKGROUND: The internet is now the primary source of information that young people use to get information on issues related to sex, contraception, and sexually transmitted infections. OBJECTIVE: The goal of the research was to review the scientific literature related to the use of Web 2.0 tools as opposed to other strategies in the prevention of curable sexually transmitted diseases (STDs). METHODS: A scoping review was performed on the documentation indexed in the bibliographic databases MEDLINE, Cochrane Library, Scopus, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Literatura Latinoamericana y del Caribe en Ciencias de la Salud, PsycINFO, Educational Resources Information Center, the databases of Centro Superior de Investigaciones Cientificas in Spain, and the Indice Bibliografico Espanol de Ciencias de la Salud from the first available date according to the characteristics of each database until April 2017. The equation search was realized by means of the using of descriptors together with the consultation of the fields of title register and summary with free terms. Bibliographies of the selected papers were searched for additional articles. RESULTS: A total of 627 references were retrieved, of which 6 papers were selected after applying the inclusion and exclusion criteria. The STDs studied were chlamydia, gonorrhea, and syphilis. The Web 2.0 tools used were Facebook, Twitter, Instagram, and YouTube. The 6 papers used Web 2.0 in the promotion of STD detection. CONCLUSIONS: Web 2.0 tools have demonstrated a positive effect on the promotion of prevention strategies for STDs and can help attract and link youth to campaigns related to sexual health. These tools can be combined with other interventions. In any case, Web 2.0 and especially Facebook have all the potential to become essential instruments for public health. PMID- 29567634 TI - Standalone Effects of a Cognitive Behavioral Intervention Using a Mobile Phone App on Psychological Distress and Alcohol Consumption Among Japanese Workers: Pilot Nonrandomized Controlled Trial. AB - BACKGROUND: Research that investigates standalone effects of a mobile phone-based cognitive behavioral therapy without any human contact for reducing both psychological distress and risky drinking has been advancing; however, the number of studies is still limited. A mobile phone app called Self Record that facilitates cognitive restructuring through self-monitoring of daily thoughts and activities was developed in Japan. OBJECTIVE: This study conducted a nonrandomized controlled pilot trial of the Self Record app to investigate standalone effects of the intervention on psychological distress and alcohol consumption among Japanese workers. Additionally, we examined moderating effects of negative mood regulation expectancies, which are beliefs about one's ability to control one's negative mood. METHODS: A quasi-experimental design with a 1 month follow-up was conducted online in Japan from February 2016 to March 2016. A research marketing company recruited participants. The selection criteria were being a Japanese full-time worker (age 20-59 years), experiencing mild to moderate psychological distress, and having some interest in self-record apps. Assignment to group was based on participants' willingness to use the app in the study. All participants completed outcome measures of negative mood regulation expectancies, positive well-being, general distress, depression, anxiety, and typical/most weekly alcohol consumption. RESULTS: From the recruitment, 15.65% (1083/6921) of participants met the inclusion criteria. Of these, 51.43% (557/1083) enrolled in the study: 54.9% (306/557) in the intervention group and 45.1% (251/557) in the control group. At the 1-month follow-up, 15.3% (85/557) of participants had dropped out. Intention-to-treat analyses revealed that participants in the intervention group reported increased typical drinking (eta2=.009) and heavy drinking (eta2=.001). Adherence to using the app was low; 64.8% (199/306) of participants in the intervention group discontinued using the app on the first day. Additionally, 65.7% (366/557) of the total sample did not correctly answer the validity checks in the outcome measures (eg, "Please select 'mildly agree' for this item"). Therefore, per-protocol analyses were conducted after removing these participants. Results showed that continuing app users (42/127) in the intervention group reported increases in anxiety (eta2=.006), typical drinking (eta2=.005), and heavy drinking (eta2=.007) compared to those in the control group (85/127). Negative mood regulation expectancies moderated the effects of the intervention for general distress (beta=.39). CONCLUSIONS: Results were contrary to our hypotheses. Self-recording methods of standalone mobile phone interventions may heighten individuals' awareness of their pathological thought and drinking behavior, but may be insufficient to decrease them unless combined with a more intense or face-to-face intervention. Limitations include high attrition in this study; measures to improve the response rate are discussed. PMID- 29567636 TI - Pregnant Women Sharing Pregnancy-Related Information on Facebook: Web-Based Survey Study. AB - BACKGROUND: Research indicates expectant and new mothers use the Internet, specifically social media, to gain information and support during the transition to parenthood. Although parents regularly share information about and photos of their child or children on Facebook, researchers have neither explored the use of Facebook to share pregnancy-related information nor investigated factors that influence such sharing. OBJECTIVE: The aim of this study was to address a gap in the literature by exploring the use of Facebook by pregnant women. Specifically, the study examined the use of Facebook to share pregnancy-related information, as well as any association between prenatal attachment and the aforementioned aspects of sharing pregnancy-related information on Facebook. METHODS: Pregnant women who were at least 18 years of age were recruited for participation in the study through posts and paid advertisements on Facebook and posts to professional organization listservs. Individuals interested in participating were directed to a secure Web-based survey system where they completed the consent form and the survey that focused on their current pregnancy. Participants completed the Maternal Antenatal Attachment Scale and answered questions that assessed how often they shared pregnancy-related information on Facebook, who they shared it with, why they shared it, and what they shared. RESULTS: A total of 117 pregnant women completed the survey. Descriptive statistics indicated that the pregnancy announcement was most commonly shared (75/108, 69.4%), with most women sharing pregnancy-related information on Facebook less than monthly (52/117, 44.4%) with only family and friends (90/116, 77.6% and 91/116, 78.4%, respectively) and for the purpose of involving others or sharing the experience (62/107, 57.9%). Correlation and regression analyses showed that prenatal attachment, in general, was positively and significantly related to all aspects of sharing pregnancy related information at the P<.05 level, with the exception of sharing because of expectations. Quality of attachment, which involves the positive feelings the woman has about her unborn child, was significantly associated with sharing to involve others or share the pregnancy (t8,93=2.654 , P=.009). In contrast, after controlling for other variables, the strength or preoccupation component of prenatal attachment was significantly associated with frequency of sharing (t8,100=2.554 , P=.01), number to types of information shared (t8,97=2.605 , P=.01), number of groups with whom shared (t8,99=3.467, P=.001), and sharing to get advice (chi28=5.339 , P=.02). CONCLUSIONS: Pregnant women in this study used Facebook for a variety of reasons, demonstrating the use of the social media platform during pregnancy for supportive and informational purposes. Overall, the results of this study are likely to be useful to professionals who are seeking alternative methods for providing intervention, information, and support to pregnant women via social media in our technology-driven society. PMID- 29567635 TI - Using Fitness Trackers and Smartwatches to Measure Physical Activity in Research: Analysis of Consumer Wrist-Worn Wearables. AB - BACKGROUND: New fitness trackers and smartwatches are released to the consumer market every year. These devices are equipped with different sensors, algorithms, and accompanying mobile apps. With recent advances in mobile sensor technology, privately collected physical activity data can be used as an addition to existing methods for health data collection in research. Furthermore, data collected from these devices have possible applications in patient diagnostics and treatment. With an increasing number of diverse brands, there is a need for an overview of device sensor support, as well as device applicability in research projects. OBJECTIVE: The objective of this study was to examine the availability of wrist worn fitness wearables and analyze availability of relevant fitness sensors from 2011 to 2017. Furthermore, the study was designed to assess brand usage in research projects, compare common brands in terms of developer access to collected health data, and features to consider when deciding which brand to use in future research. METHODS: We searched for devices and brand names in six wearable device databases. For each brand, we identified additional devices on official brand websites. The search was limited to wrist-worn fitness wearables with accelerometers, for which we mapped brand, release year, and supported sensors relevant for fitness tracking. In addition, we conducted a Medical Literature Analysis and Retrieval System Online (MEDLINE) and ClinicalTrials search to determine brand usage in research projects. Finally, we investigated developer accessibility to the health data collected by identified brands. RESULTS: We identified 423 unique devices from 132 different brands. Forty-seven percent of brands released only one device. Introduction of new brands peaked in 2014, and the highest number of new devices was introduced in 2015. Sensor support increased every year, and in addition to the accelerometer, a photoplethysmograph, for estimating heart rate, was the most common sensor. Out of the brands currently available, the five most often used in research projects are Fitbit, Garmin, Misfit, Apple, and Polar. Fitbit is used in twice as many validation studies as any other brands and is registered in ClinicalTrials studies 10 times as often as other brands. CONCLUSIONS: The wearable landscape is in constant change. New devices and brands are released every year, promising improved measurements and user experience. At the same time, other brands disappear from the consumer market for various reasons. Advances in device quality offer new opportunities for research. However, only a few well established brands are frequently used in research projects, and even less are thoroughly validated. PMID- 29567637 TI - Patient and Family Engagement in the Design of a Mobile Health Solution for Pediatric Asthma: Development and Feasibility Study. AB - BACKGROUND: Asthma is a highly prevalent, chronic disease with significant morbidity, cost, and disparities in health outcomes. While adherence to asthma treatment guidelines can improve symptoms and decrease exacerbations, most patients receive care that is not guideline-based. New approaches that incorporate shared decision-making (SDM) and health information technology (IT) are needed to positively impact asthma management. Despite the promise of health IT to improve efficiency and outcomes in health care, new IT solutions frequently suffer from a lack of widespread adoption and do not achieve desired results, as a consequence of not involving end-users in design. OBJECTIVE: To describe a case study of a pediatric asthma SDM health IT solution's development and demonstrate a methodology for engaging actual patients and families in IT development. Perspectives are shared from the vantage point of the research team and a parent of a child with asthma, who participated on the development team. METHODS: We adapted user-centric design principles to engage actual users across three main development phases: project initiation, ideation, and usability testing. To facilitate the necessary level of user engagement, our approach included: (1) a Development Workgroup consisting of patients, caregivers, and providers who met regularly with the research team; and (2) "real-world users" consisting of patients, caregivers, and providers recruited from a variety of care locations, including safety-net clinics. RESULTS: Using this methodology, we successful partnered with asthma patients and families to create an interactive, digital solution called Carolinas Asthma Coach. Carolinas Asthma Coach incorporates SDM principles to elicit patient information, including goals and preferences, and provides health-literate, tailored education with specific guideline-based recommendations for patients and their providers. Of the patients, caregivers, and providers surveyed, 100% (n=60) said they would recommend Carolinas Asthma Coach to a friend or colleague. Qualitative feedback from users provided support for the usability and engaging nature of the app. CONCLUSIONS: This project demonstrates the feasibility and benefits of deploying user-centric design methods that engage real patients and caregivers throughout the health IT design process.

PMID- 29567638 TI - Just-in-Time Feedback in Diet and Physical Activity Interventions: Systematic Review and Practical Design Framework. AB - BACKGROUND: The integration of body-worn sensors with mobile devices presents a tremendous opportunity to improve just-in-time behavioral interventions by enhancing bidirectional communication between investigators and their participants. This approach can be used to deliver supportive feedback at critical moments to optimize the attainment of health behavior goals. OBJECTIVE: The goals of this systematic review were to summarize data on the content characteristics of feedback messaging used in diet and physical activity (PA) interventions and to develop a practical framework for designing just-in-time feedback for behavioral interventions. METHODS: Interventions that included just in-time feedback on PA, sedentary behavior, or dietary intake were eligible for inclusion. Feedback content and efficacy data were synthesized descriptively. RESULTS: The review included 31 studies (15/31, 48%, targeting PA or sedentary behavior only; 13/31, 42%, targeting diet and PA; and 3/31, 10%, targeting diet only). All studies used just-in-time feedback, 30 (97%, 30/31) used personalized feedback, and 24 (78%, 24/31) used goal-oriented feedback, but only 5 (16%, 5/31) used actionable feedback. Of the 9 studies that tested the efficacy of providing feedback to promote behavior change, 4 reported significant improvements in health behavior. In 3 of these 4 studies, feedback was continuously available, goal-oriented, or actionable. CONCLUSIONS: Feedback that was continuously available, personalized, and actionable relative to a known behavioral objective was prominent in intervention studies with significant behavior change outcomes. Future research should determine whether all or some of these characteristics are needed to optimize the effect of feedback in just-in-time interventions.

AB - OBJECTIVE: This study updates previous estimates of the economic burden of diagnosed diabetes and quantifies the increased health resource use and lost productivity associated with diabetes in 2017. RESEARCH DESIGN AND METHODS: We use a prevalence-based approach that combines the demographics of the U.S. population in 2017 with diabetes prevalence, epidemiological data, health care cost, and economic data into a Cost of Diabetes Model. Health resource use and associated medical costs are analyzed by age, sex, race/ethnicity, insurance coverage, medical condition, and health service category. Data sources include national surveys, Medicare standard analytical files, and one of the largest claims databases for the commercially insured population in the U.S. RESULTS: The total estimated cost of diagnosed diabetes in 2017 is $327 billion, including $237 billion in direct medical costs and $90 billion in reduced productivity. For the cost categories analyzed, care for people with diagnosed diabetes accounts for 1 in 4 health care dollars in the U.S., and more than half of that expenditure is directly attributable to diabetes. People with diagnosed diabetes incur average medical expenditures of ~$16,750 per year, of which ~$9,600 is attributed to diabetes. People with diagnosed diabetes, on average, have medical expenditures ~2.3 times higher than what expenditures would be in the absence of diabetes. Indirect costs include increased absenteeism ($3.3 billion) and reduced productivity while at work ($26.9 billion) for the employed population, reduced productivity for those not in the labor force ($2.3 billion), inability to work because of disease-related disability ($37.5 billion), and lost productivity due to 277,000 premature deaths attributed to diabetes ($19.9 billion). CONCLUSIONS: After adjusting for inflation, economic costs of diabetes increased by 26% from 2012 to 2017 due to the increased prevalence of diabetes and the increased cost per person with diabetes. The growth in diabetes prevalence and medical costs is primarily among the population aged 65 years and older, contributing to a growing economic cost to the Medicare program. The estimates in this article highlight the substantial financial burden that diabetes imposes on society, in addition to intangible costs from pain and suffering, resources from care provided by nonpaid caregivers, and costs associated with undiagnosed diabetes. PMID- 29567640 TI - Developing in 3D: the role of CTCF in cell differentiation. AB - CTCF is a highly conserved zinc-finger DNA-binding protein that mediates interactions between distant sequences in the genome. As a consequence, CTCF regulates enhancer-promoter interactions and contributes to the three-dimensional organization of the genome. Recent studies indicate that CTCF is developmentally regulated, suggesting that it plays a role in cell type-specific genome organization. Here, we review these studies and discuss how CTCF functions during the development of various cell and tissue types, ranging from embryonic stem cells and gametes, to neural, muscle and cardiac cells. We propose that the lineage-specific control of CTCF levels, and its partnership with lineage specific transcription factors, allows for the control of cell type-specific gene expression via chromatin looping. PMID- 29567644 TI - Paligenosis: prepare to regenerate! PMID- 29567643 TI - Structural centrosome aberrations promote non-cell-autonomous invasiveness. AB - Centrosomes are the main microtubule-organizing centers of animal cells. Although centrosome aberrations are common in tumors, their consequences remain subject to debate. Here, we studied the impact of structural centrosome aberrations, induced by deregulated expression of ninein-like protein (NLP), on epithelial spheres grown in Matrigel matrices. We demonstrate that NLP-induced structural centrosome aberrations trigger the escape ("budding") of living cells from epithelia. Remarkably, all cells disseminating into the matrix were undergoing mitosis. This invasive behavior reflects a novel mechanism that depends on the acquisition of two distinct properties. First, NLP-induced centrosome aberrations trigger a re organization of the cytoskeleton, which stabilizes microtubules and weakens E cadherin junctions during mitosis. Second, atomic force microscopy reveals that cells harboring these centrosome aberrations display increased stiffness. As a consequence, mitotic cells are pushed out of mosaic epithelia, particularly if they lack centrosome aberrations. We conclude that centrosome aberrations can trigger cell dissemination through a novel, non-cell-autonomous mechanism, raising the prospect that centrosome aberrations contribute to the dissemination of metastatic cells harboring normal centrosomes.

PMID- 29567645 TI - PTRN-1/CAMSAP promotes CYK-1/formin-dependent actin polymerization during endocytic recycling. AB - Cargo sorting and membrane carrier initiation in recycling endosomes require appropriately coordinated actin dynamics. However, the mechanism underlying the regulation of actin organization during recycling transport remains elusive. Here we report that the loss of PTRN-1/CAMSAP stalled actin exchange and diminished the cytosolic actin structures. Furthermore, we found that PTRN-1 is required for the recycling of clathrin-independent cargo hTAC-GFP The N-terminal calponin homology (CH) domain and central coiled-coils (CC) region of PTRN-1 can synergistically sustain the flow of hTAC-GFP We identified CYK-1/formin as a binding partner of PTRN-1. The N-terminal GTPase-binding domain (GBD) of CYK-1 serves as the binding interface for the PTRN-1 CH domain. The presence of the PTRN-1 CH domain promoted CYK-1-mediated actin polymerization, which suggests that the PTRN-1-CH:CYK-1-GBD interaction efficiently relieves autoinhibitory interactions within CYK-1. As expected, the overexpression of the CYK-1 formin homology domain 2 (FH2) substantially restored actin structures and partially suppressed the hTAC-GFP overaccumulation phenotype in ptrn-1 mutants. We conclude that the PTRN-1 CH domain is required to stimulate CYK-1 to facilitate actin dynamics during endocytic recycling. PMID- 29567648 TI - A tough one to swallow. PMID- 29567647 TI - Increased liver tumor formation in neutral sphingomyelinase-2-deficient mice. AB - Sphingolipids are key signaling lipids in cancer. Genome-wide studies have identified neutral SMase-2 (nSMase2), an enzyme generating ceramide from SM, as a potential repressor for hepatocellular carcinoma. However, little is known about the sphingolipids regulated by nSMase2 and their roles in liver tumor development. We discovered growth of spontaneous liver tumors in 27.3% (9 of 33) of aged male nSMase2-deficient (fro/fro) mice. Lipidomics analysis showed a marked increase of SM in the tumor. Unexpectedly, tumor tissues presented with more than a 7-fold increase of C16-ceramide, concurrent with upregulation of ceramide synthase 5. The fro/fro liver tumor, but not adjacent tissue, exhibited substantial accumulation of lipid droplets, suggesting that nSMase2 deficiency is associated with tumor growth and increased neutral lipid generation in the tumor. Tumor tissue expressed significantly increased levels of CD133 and EpCAM mRNA, two markers of liver cancer stem-like cells (CSCs) and higher levels of phosphorylated signal transducer and activator of transcription 3, an essential regulator of stemness. CD133(+) cells showed strong labeling for SM and ceramide. In conclusion, these results suggest that SMase-2 deficiency plays a role in the survival or proliferation of CSCs, leading to spontaneous tumors, which is associated with tumor-specific effects on lipid homeostasis.

PMID- 29567650 TI - The New Low-Profile WEB 17 System for Treatment of Intracranial Aneurysms: First Clinical Experiences. AB - BACKGROUND AND PURPOSE: The Woven EndoBridge (WEB) is an intrasaccular flow diverter intended to treat wide-neck aneurysms. The latest generation WEBs needed a 0.021-inch microcatheter in the small sizes. Recently, a lower profile range of WEBs compliant with a 0.017-inch microcatheter (WEB 17) has been introduced. We present the first clinical results of treatment of both ruptured and unruptured aneurysms with the WEB 17. MATERIALS AND METHODS: Between December 2016 and September 2017, forty-six aneurysms in 40 patients were treated with the WEB 17. No supporting stents or balloons were used. Twenty-five aneurysms were ruptured (54%). There were 6 men and 34 women (mean age, 62 years; median, 63 years; range, 46-87 years). The mean aneurysm size was 4.9 mm (median, 5 mm; range, 2-7 mm). RESULTS: There were 2 thromboembolic procedural complications without clinical sequelae and no ruptures. The overall permanent procedural complication rate was 0% (0 of 40; 97.5% CI, 0%-10.4%). Imaging follow-up at 3 months was available in 33 patients with 39 aneurysms (97.5% of 40 eligible aneurysms). In 1 aneurysm, the detached WEB was undersized and the remnant was additionally treated with coils after 1 week. This same aneurysm reopened at 3 months and was again treated with a second WEB. One other aneurysm showed persistent WEB filling at 3 months. Complete occlusion was achieved in 28 of 39 aneurysms (72%), and 9 aneurysms (23%) showed a neck remnant. CONCLUSIONS: The WEB 17 is safe and effective for both ruptured and unruptured aneurysms. The WEB 17 is a valuable addition to the existing WEB size range, especially for very small aneurysms. PMID- 29567651 TI - Brain MRI Characteristics of Patients with Anti-N-Methyl-D-Aspartate Receptor Encephalitis and Their Associations with 2-Year Clinical Outcome. AB - BACKGROUND AND PURPOSE: Anti-N-methyl-D-aspertate receptor encephalitis is an autoimmune-mediated disease without specific brain MRI features. Our aim was to investigate the brain MR imaging characteristics of anti-N-methyl-D-aspartate receptor encephalitis and their associations with clinical outcome at a 2-year follow-up. MATERIALS AND METHODS: We enrolled 53 patients with anti-N-methyl-D aspartate receptor encephalitis and performed 2-year follow-up. Brain MRIs were acquired for all patients at the onset phase. The brain MR imaging manifestations were classified into 4 types: type 1: normal MR imaging findings; type 2: only hippocampal lesions; type 3: lesions not involving the hippocampus; and type 4: lesions in both the hippocampus and other brain areas. The modified Rankin Scale score at 2-year follow-up was assessed, and the association between the mRS and onset brain MR imaging characteristics was evaluated. RESULTS: Twenty-eight (28/53, 53%) patients had normal MR imaging findings (type 1), and the others (25/53, 47%) had abnormal MRI findings: type 2: 7 patients (13%); type 3: seven patients (13%); and type 4: eleven patients (21%). Normal brain MRI findings were more common in female patients (P = .02). Psychiatric and behavioral abnormalities were more common in adults (P = .015), and autonomic symptoms (P = .025) were more common in pediatric patients. The presence of hippocampal lesions (P = .008, OR = 9.584; 95% CI, 1.803-50.931) and relapse (P = .043, OR = 0.111; 95% CI, 0.013-0.930) was associated with poor outcome. CONCLUSIONS: Normal brain MRI findings were observed in half of the patients. Lesions in the hippocampus were the most common MR imaging abnormal finding. The presence of hippocampal lesions is the main MR imaging predictor for poor prognosis in patients with anti N-methyl-D-aspartate receptor encephalitis. PMID- 29567652 TI - Transforaminal Lumbar Puncture: An Alternative Technique in Patients with Challenging Access. AB - Interlaminar lumbar puncture and cervical puncture may not be ideal in all circumstances. Recently, we have used a transforaminal approach in selected situations. Between May 2016 and December 2017, twenty-six transforaminal lumbar punctures were performed in 9 patients (25 CT-guided, 1 fluoroscopy-guided). Seven had spinal muscular atrophy and were referred for intrathecal nusinersen administration. In 2, CT myelography was performed via transforaminal lumbar puncture. The lumbar posterior elements were completely fused in 8, and there was an overlying abscess in 1. The L1-2 level was used in 2; the L2-3 level, in 10; the L3-4 level, in 12; and the L4-5 level, in 2 procedures. Post-lumbar puncture headache was observed on 4 occasions, which resolved without blood patching. One patient felt heat and pain at the injection site that resolved spontaneously within hours. One patient had radicular pain that resolved with conservative treatment. Transforaminal lumbar puncture may become an effective alternative to classic interlaminar lumbar puncture or cervical puncture. PMID- 29567653 TI - Diagnosing Early Ischemic Changes with the Latest-Generation Flat Detector CT: A Comparative Study with Multidetector CT. AB - BACKGROUND AND PURPOSE: One-stop management of mechanical thrombectomy-eligible patients with large-vessel occlusion represents an innovative approach in acute stroke treatment. This approach reduces door-to-reperfusion times by omitting multidetector CT, using flat detector CT as pre-mechanical thrombectomy imaging. The purpose of this study was to compare the diagnostic performance of the latest generation flat detector CT with multidetector CT. MATERIALS AND METHODS: Prospectively derived data from patients with ischemic stroke with large-vessel occlusion and mechanical thrombectomy were analyzed in this monocentric study. All included patients underwent multidetector CT before referral to our comprehensive stroke center and flat detector CT in the angiography suite before mechanical thrombectomy. Diagnosis of early ischemic signs, quantified by the ASPECTS, was compared between modalities using cross tables, the Pearson correlation, and Bland-Altman plots. The predictive value of multidetector CT- and flat detector CT-derived ASPECTS for functional outcome was investigated using area under the receiver operating characteristic curve analysis. RESULTS: Of 25 patients, 24 (96%) had flat detector CT with sufficient diagnostic quality. Median multidetector CT and flat detector CT ASPECTSs were 7 (interquartile range, 5.5-9 and 4.25-8, respectively) with a mean period of 143.6 +/- 49.5 minutes between both modalities. The overall sensitivity was 85.1% and specificity was 83.1% for flat detector CT ASPECTS compared with multidetector CT ASPECTS as the reference technique. Multidetector CT and flat detector CT ASPECTS were strongly correlated (r = 0.849, P < .001) and moderately predicted functional outcome (area under the receiver operating characteristic curve, 0.738; P = .007 and .715; P = .069, respectively). CONCLUSIONS: Determination of ASPECTS on flat detector CT is feasible, showing no significant difference compared with multidetector CT ASPECTS and a similar predictive value for functional outcome. Our findings support the use of flat detector CT for emergency stroke imaging before mechanical thrombectomy to reduce door-to-groin time. PMID- 29567654 TI - Endovascular Management of Acute Stroke in the Elderly: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Acute ischemic stroke occurs more frequently, presents with more severe symptoms, and has worse outcomes in elderly patients. The safety and efficacy of endovascular therapy for acute stroke in this age group has not been fully established. PURPOSE: We present the results of a systematic review and meta-analysis examining clinical, procedural, and radiologic outcomes of endovascular therapy for acute stroke in patients older than 80 years of age. DATA SOURCES: We searched PubMed, MEDLINE, and EMBASE from 1992 to week 35 of 2017 for studies evaluating endovascular therapy for acute stroke in the elderly. STUDY SELECTION: Two independent reviewers selected studies and abstracted data. The primary end point was good functional outcome at 3 months defined as modified Rankin Scale score of <=2. DATA ANALYSIS: Data were analyzed using random-effects meta-analysis. DATA SYNTHESIS: Seventeen studies reporting on 860 patients were included. The rate of good functional outcome at 3 months was 27% (95% CI, 21% 32%). Mortality at 3 months was 34% (95% CI, 23%-44%). Successful recanalization was achieved in 78% of patients (95% CI, 72%-85%). Procedure-related complications occurred in 11% (95% CI, 4%-17%). The incidence of intracranial hemorrhage was 24% (95% CI, 15%-32%), and for symptomatic intracranial hemorrhage, it was 8% (95% CI, 5%-10%). The mean time to groin was 251 minutes (95% CI, 224-278 minutes). Procedure time was 99 minutes (95% CI, 67-131 minutes). LIMITATIONS: I2 values were above 50% for all outcomes, indicating substantial heterogeneity. CONCLUSIONS: Good functional recovery in octogenarians treated with endovascular therapy for acute stroke can be achieved in a high proportion of patients despite the higher incidence of comorbidity in this cohort. Outcomes are inferior to those reported for younger patients; however, endovascular therapy can allow at least 1 in 4 patients older than 80 years of age to regain independent function at 3 months. More research is required to improve patient selection in the elderly, but age should not be a discriminator when deciding to offer endovascular therapy for patients with acute stroke. PMID- 29567655 TI - 3D Deep Learning Angiography (3D-DLA) from C-arm Conebeam CT. AB - BACKGROUND AND PURPOSE: Deep learning is a branch of artificial intelligence that has demonstrated unprecedented performance in many medical imaging applications. Our purpose was to develop a deep learning angiography method to generate 3D cerebral angiograms from a single contrast-enhanced C-arm conebeam CT acquisition in order to reduce image artifacts and radiation dose. MATERIALS AND METHODS: A set of 105 3D rotational angiography examinations were randomly selected from an internal data base. All were acquired using a clinical system in conjunction with a standard injection protocol. More than 150 million labeled voxels from 35 subjects were used for training. A deep convolutional neural network was trained to classify each image voxel into 3 tissue types (vasculature, bone, and soft tissue). The trained deep learning angiography model was then applied for tissue classification into a validation cohort of 8 subjects and a final testing cohort of the remaining 62 subjects. The final vasculature tissue class was used to generate the 3D deep learning angiography images. To quantify the generalization error of the trained model, we calculated the accuracy, sensitivity, precision, and Dice similarity coefficients for vasculature classification in relevant anatomy. The 3D deep learning angiography and clinical 3D rotational angiography images were subjected to a qualitative assessment for the presence of intersweep motion artifacts. RESULTS: Vasculature classification accuracy and 95% CI in the testing dataset were 98.7% (98.3%-99.1%). No residual signal from osseous structures was observed for any 3D deep learning angiography testing cases except for small regions in the otic capsule and nasal cavity compared with 37% (23/62) of the 3D rotational angiographies. CONCLUSIONS: Deep learning angiography accurately recreated the vascular anatomy of the 3D rotational angiography reconstructions without a mask. Deep learning angiography reduced misregistration artifacts induced by intersweep motion, and it reduced radiation exposure required to obtain clinically useful 3D rotational angiography. PMID- 29567656 TI - Cerebellar Growth Impairment Characterizes School-Aged Children Born Preterm without Perinatal Brain Lesions. AB - BACKGROUND AND PURPOSE: Infants born preterm are commonly diagnosed with structural brain lesions known to affect long-term neurodevelopment negatively. Yet, the effects of preterm birth on brain development in the absence of intracranial lesions remain to be studied in detail. In this study, we aim to quantify long term consequences of preterm birth on brain development in this specific group. MATERIALS AND METHODS: Neonatal cranial sonography and follow-up T1-weighted MR imaging and DTI were performed to evaluate whether the anatomic characteristics of the cerebrum and cerebellum in a cohort of school-aged children (6-12 years of age) were related to gestational age at birth in children free of brain lesions in the perinatal period. RESULTS: In the cohort consisting of 36 preterm (28-37 weeks' gestational age) and 66 term-born infants, T1 weighted MR imaging and DTI at 6-12 years revealed a reduction of cerebellar white matter volume (beta = 0.387, P < .001), altered fractional anisotropy of cerebellar white matter (beta = -0.236, P = .02), and a reduction of cerebellar gray and white matter surface area (beta = 0.337, P < .001; beta = 0.375, P < .001, respectively) in relation to birth age. Such relations were not observed for the cerebral cortex or white matter volume, surface area, or diffusion quantities. CONCLUSIONS: The results of our study show that perinatal influences that are not primarily neurologic are still able to disturb long-term neurodevelopment, particularly of the developing cerebellum. Including the cerebellum in future neuroprotective strategies seems therefore essential. PMID- 29567657 TI - Factors Influencing Confidence in Diagnostic Ratings and Retreatment Recommendations in Coiled Aneurysms. AB - BACKGROUND AND PURPOSE: Angiographic occlusion and retreatment of coiled aneurysms are commonly used as surrogate end points in clinical trials. We aimed to evaluate the influence of aneurysm, patient, and rater characteristics on the confidence of visual evaluation of aneurysm coiling and retreatment decisions. MATERIALS AND METHODS: Twenty-six participants of the Advanced Course in Endovascular Interventional Neuroradiology of the European Society of Neuroradiology were asked to evaluate digital subtraction angiography examinations of patients who had undergone endovascular coiling, by determining the grade of aneurysm occlusion, the change between immediate postprocedural and follow-up angiograms, their level of confidence, the technical difficulty of retreatment, and the best therapeutic approach. The experience, knowledge, and skills of each participant were assessed. The influence of rater and case characteristics on indicated confidence in diagnostic ratings and retreatment recommendations was analyzed. RESULTS: Interrater reliability was moderate regarding the assessment of aneurysm occlusion grade (intraclass correlation coefficient = 0.581) and substantial regarding change (intraclass correlation coefficient = 0.776). Overall confidence in the diagnostic rating was high (median, "very certain"). Confidence was statistically significantly higher in cases that were generally rated as "worse." The odds of recommending retreatment were significantly higher in cases that were generally rated with higher mean confidence. CONCLUSIONS: Although overall confidence in the diagnostic rating was high, our study confirms the suboptimal interrater reliability of visual assessment of aneurysm occlusion as well as retreatment recommendations, rendering both questionable as primary outcome measures. Besides recurrence status, recommendation of retreatment is significantly influenced by patient age, aneurysm neck width, and characteristics of the therapist. PMID- 29567660 TI - Noninvasive Detection of Cocaine and Heroin Use with Single Fingerprints: Determination of an Environmental Cutoff. AB - BACKGROUND: Recent publications have explored the possibility of using fingerprints to confirm drug use, but none has yet dealt with environmental contamination from fingertips. Here we explored the possibility of establishing an environmental cutoff for drug testing from a single fingerprint. METHODS: Fingerprint samples (n = 100) were collected from the hands of 50 nondrug users before and after handwashing to establish separate environmental cutoff values and testing protocols for cocaine, benzoylecgonine, heroin, and 6 monoacetylmorphine. The cutoff was challenged by testing the fingerprints of drug free volunteers after shaking hands with drug users. Fingerprints from patients who testified to taking cocaine (n = 32) and heroin (n = 24) were also collected and analyzed. RESULTS: A different cutoff value needed to be applied, depending on whether the fingerprints were collected as presented or after handwashing. Applying these cutoffs gave a 0% false-positive rate from the drug-free volunteers. After application of the cutoff, the detection rate (compared to patient testimony) for washed hands of patients was 87.5% for cocaine use and 100% for heroin use. CONCLUSIONS: Fingerprints show enhanced levels of cocaine, heroin, and their respective metabolites in patients who testified to taking the substances, compared with the population of naive drug users surveyed, and a cutoff (decision level) can be established. The cutoff is robust enough to account for small increases in analyte observed after secondary transfer. PMID- 29567658 TI - Establishment of Signaling Interactions with Cellular Resolution for Every Cell Cycle of Embryogenesis. AB - Intercellular signaling interactions play a key role in breaking fate symmetry during animal development. Identification of signaling interactions at cellular resolution is technically challenging, especially in a developing embryo. Here, we develop a platform that allows automated inference and validation of signaling interactions for every cell cycle of Caenorhabditis elegans embryogenesis. This is achieved by the generation of a systems-level cell contact map, which consists of 1114 highly confident intercellular contacts, by modeling analysis and is validated through cell membrane labeling coupled with cell lineage analysis. We apply the map to identify cell pairs between which a Notch signaling interaction takes place. By generating expression patterns for two ligands and two receptors of the Notch signaling pathway with cellular resolution using the automated expression profiling technique, we are able to refine existing and identify novel Notch interactions during C. elegans embryogenesis. Targeted cell ablation followed by cell lineage analysis demonstrates the roles of signaling interactions during cell division in breaking fate symmetry. Finally, we describe the development of a website that allows online access to the cell-cell contact map for mapping of other signaling interactions by the community. The platform can be adapted to establish cellular interactions from any other signaling pathway. PMID- 29567661 TI - Quality Control of Serum and Plasma by Quantification of (4E,14Z)-Sphingadienine C18-1-Phosphate Uncovers Common Preanalytical Errors During Handling of Whole Blood. AB - BACKGROUND: Nonadherence to standard operating procedures (SOPs) during handling and processing of whole blood is one of the most frequent causes affecting the quality of serum and plasma. Yet, the quality of blood samples is of the utmost importance for reliable, conclusive research findings, valid diagnostics, and appropriate therapeutic decisions. METHODS: UHPLC-MS-driven nontargeted metabolomics was applied to identify biomarkers that reflected time to processing of blood samples, and a targeted UHPLC-MS analysis was used to quantify and validate these biomarkers. RESULTS: We found that (4E,14Z)-sphingadienine-C18-1 phosphate (S1P-d18:2) was suitable for the reliable assessment of the pronounced changes in the quality of serum and plasma caused by errors in the phase between collection and centrifugation of whole blood samples. We rigorously validated S1P d18:2, which included the use of practicality tests on >1400 randomly selected serum and plasma samples that were originally collected during single- and multicenter trials and then stored in 11 biobanks in 3 countries. Neither life threatening disease states nor strenuous metabolic challenges (i.e., high intensity exercise) affected the concentration of S1P-d18:2. Cutoff values for sample assessment were defined (plasma, <=0.085 MUg/mL; serum, <=0.154 MUg/mL). CONCLUSIONS: Unbiased valid monitoring to check for adherence to SOP-dictated time for processing to plasma or serum and/or time to storage of whole blood at 4 degrees C is now feasible. This novel quality assessment step could enable scientists to uncover common preanalytical errors, allowing for identification of serum and plasma samples that should be excluded from certain investigations. It should also allow control of samples before long-term storage in biobanks. PMID- 29567659 TI - Genetic Drivers of Pancreatic Islet Function. AB - The majority of gene loci that have been associated with type 2 diabetes play a role in pancreatic islet function. To evaluate the role of islet gene expression in the etiology of diabetes, we sensitized a genetically diverse mouse population with a Western diet high in fat (45% kcal) and sucrose (34%) and carried out genome-wide association mapping of diabetes-related phenotypes. We quantified mRNA abundance in the islets and identified 18,820 expression QTL. We applied mediation analysis to identify candidate causal driver genes at loci that affect the abundance of numerous transcripts. These include two genes previously associated with monogenic diabetes (PDX1 and HNF4A), as well as three genes with nominal association with diabetes-related traits in humans (FAM83E, IL6ST, and SAT2). We grouped transcripts into gene modules and mapped regulatory loci for modules enriched with transcripts specific for alpha-cells, and another specific for delta-cells. However, no single module enriched for beta-cell-specific transcripts, suggesting heterogeneity of gene expression patterns within the beta cell population. A module enriched in transcripts associated with branched-chain amino acid metabolism was the most strongly correlated with physiological traits that reflect insulin resistance. Although the mice in this study were not overtly diabetic, the analysis of pancreatic islet gene expression under dietary-induced stress enabled us to identify correlated variation in groups of genes that are functionally linked to diabetes-associated physiological traits. Our analysis suggests an expected degree of concordance between diabetes-associated loci in the mouse and those found in human populations, and demonstrates how the mouse can provide evidence to support nominal associations found in human genome-wide association mapping. PMID- 29567662 TI - Wheat miR9678 Affects Seed Germination by Generating Phased siRNAs and Modulating Abscisic Acid/Gibberellin Signaling. AB - Seed germination is important for grain yield and quality and rapid, near simultaneous germination helps in cultivation; however, cultivars that germinate too readily can undergo preharvest sprouting (PHS), which causes substantial losses in areas that tend to get rain around harvest time. Moreover, our knowledge of mechanisms regulating seed germination in wheat (Triticum aestivum) remains limited. In this study, we analyzed function of a wheat-specific microRNA 9678 (miR9678), which is specifically expressed in the scutellum of developing and germinating seeds. Overexpression of miR9678 delayed germination and improved resistance to PHS in wheat through reducing bioactive gibberellin (GA) levels; miR9678 silencing enhanced germination rates. We provide evidence that miR9678 targets a long noncoding RNA (WSGAR) and triggers the generation of phased small interfering RNAs that play a role in the delay of seed germination. Finally, we found that abscisic acid (ABA) signaling proteins bind the promoter of miR9678 precursor and activate its expression, indicating that miR9678 affects germination by modulating the GA/ABA signaling. PMID- 29567663 TI - The Ubiquitin E3 Ligase PRU1 Regulates WRKY6 Degradation to Modulate Phosphate Homeostasis in Response to Low-Pi Stress in Arabidopsis. AB - Since phosphorus is an essential nutrient for plants, plants have evolved a number of adaptive mechanisms to respond to changes in phosphate (Pi) supply. Previously, we reported that the transcription factor WRKY6 modulates Pi homeostasis by downregulating PHOSPHATE1 (PHO1) expression and that WRKY6 is degraded during Pi starvation in Arabidopsis thaliana However, the molecular mechanism underlying low-Pi-induced WRKY6 degradation was unknown. Here, we report that a ubiquitin E3 ligase, PHOSPHATE RESPONSE UBIQUITIN E3 LIGASE1 (PRU1), modulates WRKY6 protein levels in response to low-Pi stress. A pru1 mutant was more sensitive than the wild type to Pi-deficient conditions, exhibiting a reduced Pi contents in the shoot, similar to the pho1-2 mutant and WRKY6-overexpressing line. PRU1 interacted with WRKY6 in vitro and in vivo. Under low-Pi stress, the ubiquitination and subsequent degradation of WRKY6, as well as the consequential enhancement of PHO1 expression, were impaired in pru1 PRU1 complementation lines displayed no obvious differences compared with wild-type plants. Further genetic analysis showed that disruption of WRKY6 abolished the low-Pi sensitivity of pru1, indicating that WRKY6 functioned downstream of PRU1. Taken together, this study uncovers a mechanism by which PRU1 modulates Pi homeostasis, through regulating the abundance of WRKY6 in response to low-Pi stress in Arabidopsis. PMID- 29567664 TI - Acceptability of a parental early warning tool for parents of infants with complex congenital heart disease: a qualitative feasibility study. AB - AIM: To explore the acceptability and feasibility of a parental early warning tool, called the Congenital Heart Assessment Tool (CHAT), for parents going home with their infant between first and second stage of surgery for complex congenital heart disease. BACKGROUND: Home monitoring programmes were developed to aid early recognition of deterioration in fragile infants between first and second surgical stage. However, this necessitates good discharge preparation to enable parents to develop appropriate knowledge and understanding of signs of deterioration to look for and who to contact. DESIGN: This was a longitudinal qualitative feasibility study, within a constructivist paradigm. Parents were taught how to use the CHAT before taking their infant home and asked to participate in semistructured interviews at four time points: before discharge (T0), 2 weeks after discharge (T1), 8 weeks after discharge (T2) and after stage 2 surgery (T3). Interviews were transcribed verbatim and thematically analysed. SETTING: One tertiary children's cardiac centre in the UK. SUBJECTS: Twelve parents of eight infants who were discharged following first stage cardiac surgery for complex congenital heart disease, between August 2013 and February 2015. RESULTS: Four main themes emerged: (1) parental preparation and vigilance, (2) usability, (3) mastery, and (4) reassurance and support. CONCLUSIONS: The study highlighted the benefit of appropriately preparing parents before discharge, using the CHAT, to enable identification of normal infant behaviour and to detect signs of clinical deterioration. The study also demonstrated the importance of providing parents with information about when and who to call for management advice and support. PMID- 29567665 TI - Paediatric Ebstein's anomaly: how clinical presentation predicts mortality. AB - BACKGROUND: Forecasting the prognosis of a child when diagnosed with Ebstein's anomaly is difficult. We, therefore, studied which factors at the time of diagnosis are associated with death during childhood. METHODS: All consecutive patients (0-18 years) diagnosed with Ebstein's anomaly in the Netherlands between 1980 and 2014 were included. Survival curves were obtained using the Kaplan-Meier method. By using the Cox proportional hazard model, we analysed the factors (at diagnosis) that were associated with death. RESULTS: We included 176 patients. Thirty-one patients (18%) died before the age of 18 years. The 1-year survival was 84% and remained stable at 82% from 35 months after diagnosis and onwards. Modified Ross Heart Failure Class 4 at the time of diagnosis was the most important risk factor for death during childhood (HR 12.5, 95% CI 4.4 to 35.9). Furthermore, diagnosis in the neonatal period (HR 4.2, 95% CI 1.5 to 12.0), severe tricuspid valve regurgitation (HR 2.4, 95% CI 1.2 to 5.0), severe right ventricular outflow tract obstruction (HR 3.7, 95% CI 1.8 to 7.7) and a patent ductus arteriosus (HR 2.8, 95% CI 1.3 to 6.0) at the time of diagnosis were univariately associated with death. Multivariable analysis showed that presentation with Heart Failure Class 4 and a ventricular septal defect is the strongest predictor of death in childhood and adolescence. CONCLUSION: Patients with Ebstein's anomaly presenting with Heart Failure Class 4 and a ventricular septal defect have a high risk of death during childhood.

PMID- 29567668 TI - Muscular diagnostics and the feasibility of microsystem acupuncture as a potential adjunct in the treatment of painful temporomandibular disorders: results of a retrospective cohort study. AB - AIMS: To investigate the effect of microsystem acupuncture on painful temporomandibular disorders (TMD). METHODS: We retrospectively analysed 887 treatments in 407 TMD-patients (mean age 45+/-1.5 years), who received microsystem acupuncture (mouth, scalp or fingers) with a focus on oral acupuncture. All patients systematically underwent palpation of specific muscular tender points and their pain rating was assessed on a four-point Likert scale (no pain to strong pain) before and after treatment. In 42 cases, the pain intensity was determined using a visual analogue scale (0-100 mm). As the data were normally distributed, analysis was performed with unpaired t-tests. RESULTS: The pterygoid muscles were most painful to palpation, with the lateral pterygoid rated moderate to strong by 76% of patients and the medial pterygoid by 48% of patients. The palpation of microsystem acupuncture points revealed the strongest sensitivity (moderate or strong pain) of the oral retromolar points at the upper jaw (83%). After treatment, the pain intensity of all tender points had significantly decreased (P<0.001). The proportion of moderate to strong pain ratings was below 3% at most tender points. Overall pain intensity of the subjects (n=42) before treatment was 55.5+/-19.7 mm on the VAS scale and was significantly reduced to 29.6+/-20.9 mm (P<0.001) post-treatment. CONCLUSIONS: This analysis suggests microsystem acupuncture could reduce the pain intensity of TMD in the short term. Considering the increased local muscular tenderness, further investigations regarding the key role of myofascial trigger points in the occurrence of TMDs are warranted and could lead to new comprehensive treatment strategies. PMID- 29567669 TI - GATA6 Regulates Aortic Valve Remodeling, and Its Haploinsufficiency Leads to Right-Left Type Bicuspid Aortic Valve. AB - BACKGROUND: Bicuspid aortic valve (BAV), the most common congenital heart defect affecting 1% to 2% of the population, is a major risk factor for premature aortic valve disease and accounts for the majority of valve replacement. The genetic basis and mechanisms of BAV etiology and pathogenesis remain largely undefined. METHODS: Cardiac structure and function was assessed in mice lacking a Gata6 allele. Human GATA6 gene variants were analyzed in 452 BAV cases from the BAV consortium and 1849 controls from the Framingham GWAS (Genome Wide Association Study). GATA6 expression was determined in mice and human tissues using quantitative real-time polymerase chain reaction and immunohistochemistry. Mechanistic studies were carried out in cultured cells. RESULTS: Gata6 heterozygous mice have highly penetrant right-left (RL)-type BAV, the most frequent type in humans. GATA6 transcript levels are lower in human BAV compared with normal tricuspid valves. Mechanistically, Gata6 haploinsufficiency disrupts valve remodeling and extracellular matrix composition through dysregulation of important signaling molecules, including matrix metalloproteinase 9. Cell specific inactivation of Gata6 reveals an essential role for GATA6 in secondary heart field myocytes because loss of 1 Gata6 allele from Isl- 1-positive cells but not from endothelial or neural crest cells-recapitulates the phenotype of Gata6 heterozygous mice. CONCLUSIONS: The data identify a new cellular and molecular mechanism underlying BAV. The availability of an animal model for the most frequent human BAV opens the way for the elucidation of BAV pathogenesis and the development of much needed therapies. PMID- 29567670 TI - Conserved functional control, but distinct regulation, of cell proliferation in rice and Arabidopsis leaves revealed by comparative analysis of GRF-INTERACTING FACTOR 1 orthologs. AB - Regulation of cell proliferation is crucial for establishing the shape of plant leaves. We have identified MAKIBA3 (MKB3), a loss-of-function mutant of which exhibits a narrowed- and rolled-leaf phenotype in rice. MKB3 was found to be an ortholog of Arabidopsis ANGUSTIFOLIA3 (AN3), which positively regulates cell proliferation. The reduced leaf size of mkb3 plants with enlarged cells and the increased size of MKB3-overexpressing leaves with normal-sized cells indicate that MKB3 is a positive regulator of leaf proliferation and that mkb3 mutation triggers a compensation syndrome, as does Arabidopsis an3 Expression analysis revealed that MKB3 is predominantly expressed on the epidermis of leaf primordia, which is different from the location of AN3 A protein movement assay demonstrated that MKB3 moves from an MKB3-expressing domain to a non-expressing domain, which is required for normal leaf development. Our results suggest that rice MKB3 and Arabidopsis AN3 have conserved functions and effects on leaf development. However, the expression pattern of MKB3 and direction of protein movement are different between rice and Arabidopsis, which might reflect differences in leaf primordia development in these two species. PMID- 29567671 TI - Control of the proportion of inner cells by asymmetric divisions and the ensuing resilience of cloned rabbit embryos. AB - Mammalian embryo cloning by nuclear transfer has a low success rate. This is hypothesized to correlate with a high variability of early developmental steps that segregate outer cells, which are fated to extra-embryonic tissues, from inner cells, which give rise to the embryo proper. Exploring the cell lineage of wild-type embryos and clones, imaged in toto until hatching, highlights the respective contributions of cell proliferation, death and asymmetric divisions to phenotypic variability. Preferential cell death of inner cells in clones, probably pertaining to the epigenetic plasticity of the transferred nucleus, is identified as a major difference with effects on the proportion of inner cell. In wild type and clones, similar patterns of outer cell asymmetric divisions are shown to be essential to the robust proportion of inner cells observed in wild type. Asymmetric inner cell division, which is not described in mice, is identified as a regulator of the proportion of inner cells and likely gives rise to resilient clones. PMID- 29567672 TI - Origin and specification of type II neuroblasts in the Drosophila embryo. AB - In Drosophila, neural stem cells or neuroblasts (NBs) acquire different identities according to their site of origin in the embryonic neuroectoderm. Their identity determines the number of times they will divide and the types of daughter cells they will generate. All NBs divide asymmetrically, with type I NBs undergoing self-renewal and generating another cell that will divide only once more. By contrast, a small set of NBs in the larval brain, type II NBs, divides differently, undergoing self-renewal and generating an intermediate neural progenitor (INP) that continues to divide asymmetrically several more times, generating larger lineages. In this study, we have analysed the origin of type II NBs and how they are specified. Our results indicate that these cells originate in three distinct clusters in the dorsal protocerebrum during stage 12 of embryonic development. Moreover, it appears that their specification requires the combined action of EGFR signalling and the activity of the related genes buttonhead and Drosophila Sp1 In addition, we also show that the INPs generated in the embryo enter quiescence at the end of embryogenesis, resuming proliferation during the larval stage. PMID- 29567673 TI - Medical union: the pathway to an efficient healthcare system in China. PMID- 29567674 TI - Whole-genome sequencing of Atacama skeleton shows novel mutations linked with dysplasia. AB - Over a decade ago, the Atacama humanoid skeleton (Ata) was discovered in the Atacama region of Chile. The Ata specimen carried a strange phenotype-6-in stature, fewer than expected ribs, elongated cranium, and accelerated bone age leading to speculation that this was a preserved nonhuman primate, human fetus harboring genetic mutations, or even an extraterrestrial. We previously reported that it was human by DNA analysis with an estimated bone age of about 6-8 yr at the time of demise. To determine the possible genetic drivers of the observed morphology, DNA from the specimen was subjected to whole-genome sequencing using the Illumina HiSeq platform with an average 11.5* coverage of 101-bp, paired-end reads. In total, 3,356,569 single nucleotide variations (SNVs) were found as compared to the human reference genome, 518,365 insertions and deletions (indels), and 1047 structural variations (SVs) were detected. Here, we present the detailed whole-genome analysis showing that Ata is a female of human origin, likely of Chilean descent, and its genome harbors mutations in genes (COL1A1, COL2A1, KMT2D, FLNB, ATR, TRIP11, PCNT) previously linked with diseases of small stature, rib anomalies, cranial malformations, premature joint fusion, and osteochondrodysplasia (also known as skeletal dysplasia). Together, these findings provide a molecular characterization of Ata's peculiar phenotype, which likely results from multiple known and novel putative gene mutations affecting bone development and ossification. PMID- 29567677 TI - Parvins Are Required for Endothelial Cell-Cell Junctions and Cell Polarity During Embryonic Blood Vessel Formation. AB - OBJECTIVE: During vascular development, integrin-mediated signaling regulates the formation and stabilization of cell-cell junctions, which are required for endothelial cell (EC) apical-basal polarity and proper deposition of the vascular basement membrane. Parvins are actin-binding proteins that facilitate the interaction of integrins with the actin cytoskeleton. The endothelium expresses 2 parvin isoforms: alpha-pv (alpha-parvin) and beta-pv (beta-parvin). Recently, we have shown that alpha-pv is critical for vessel growth and vessel stability at late embryonic developmental stages. The role of parvins during early embryonic development is unknown. APPROACH AND RESULTS: To investigate the role of endothelial parvins in the developing vasculature, we generated mice with ECs lacking both parvin isoforms by deleting alpha-pv in ECs in global beta-pv-/- mice (alpha-pvDeltaEC;beta-pv-/- mice). Here, we show that alpha-pvDeltaEC;beta pv-/- mice die around embryonic day 11.5 and exhibit hemorrhages, immature capillary beds, and severe vascular defects in the central nervous system, including reduced vessel branching, increased vessel diameter, and balloon-like hemorrhagic clusters of ECs. Vessels in alpha-pvDeltaEC;beta-pv-/- embryos display disorganized cell-cell junctions, impaired endothelial apical-basal polarity, and discontinuous basement membranes. These vascular defects are accompanied by defective pericyte-vessel interaction. CONCLUSIONS: Our results show that parvins are critical for the organization of endothelial cell-cell junctions, the establishment of endothelial apical-basal polarity, and the integrity of the basement membrane. PMID- 29567675 TI - Promoter architecture determines cotranslational regulation of mRNA. AB - Information that regulates gene expression is encoded throughout each gene but if different regulatory regions can be understood in isolation, or if they interact, is unknown. Here we measure mRNA levels for 10,000 open reading frames (ORFs) transcribed from either an inducible or constitutive promoter. We find that the strength of cotranslational regulation on mRNA levels is determined by promoter architecture. By using a novel computational genetic screen of 6402 RNA-seq experiments, we identify the RNA helicase Dbp2 as the mechanism by which cotranslational regulation is reduced specifically for inducible promoters. Finally, we find that for constitutive genes, but not inducible genes, most of the information encoding regulation of mRNA levels in response to changes in growth rate is encoded in the ORF and not in the promoter. Thus, the ORF sequence is a major regulator of gene expression, and a nonlinear interaction between promoters and ORFs determines mRNA levels. PMID- 29567676 TI - Cancer-associated rs6983267 SNP and its accompanying long noncoding RNA CCAT2 induce myeloid malignancies via unique SNP-specific RNA mutations. AB - The cancer-risk-associated rs6983267 single nucleotide polymorphism (SNP) and the accompanying long noncoding RNA CCAT2 in the highly amplified 8q24.21 region have been implicated in cancer predisposition, although causality has not been established. Here, using allele-specific CCAT2 transgenic mice, we demonstrate that CCAT2 overexpression leads to spontaneous myeloid malignancies. We further identified that CCAT2 is overexpressed in bone marrow and peripheral blood of myelodysplastic/myeloproliferative neoplasms (MDS/MPN) patients. CCAT2 induces global deregulation of gene expression by down-regulating EZH2 in vitro and in vivo in an allele-specific manner. We also identified a novel non-APOBEC, non ADAR, RNA editing at the SNP locus in MDS/MPN patients and CCAT2-transgenic mice. The RNA transcribed from the SNP locus in malignant hematopoietic cells have different allelic composition from the corresponding genomic DNA, a phenomenon rarely observed in normal cells. Our findings provide fundamental insights into the functional role of rs6983267 SNP and CCAT2 in myeloid malignancies.

AB - OBJECTIVE: Aortic arch transplants have advanced our understanding of processes that contribute to progression and regression of atherosclerotic plaques. To characterize the dynamic behavior of monocytes and macrophages in atherosclerotic plaques over time, we developed a new model of cervical aortic arch transplantation in mice that is amenable to intravital imaging. APPROACH AND RESULTS: Vascularized aortic arch grafts were transplanted heterotropically to the right carotid arteries of recipient mice using microsurgical suture techniques. To image immune cells in atherosclerotic lesions during regression, plaque-bearing aortic arch grafts from B6 ApoE-deficient donors were transplanted into syngeneic CX3CR1 GFP reporter mice. Grafts were evaluated histologically, and monocytic cells in atherosclerotic plaques in ApoE-deficient grafts were imaged intravitally by 2-photon microscopy in serial fashion. In complementary experiments, CCR2+ cells in plaques were serially imaged by positron emission tomography using specific molecular probes. Plaques in ApoE-deficient grafts underwent regression after transplantation into normolipidemic hosts. Intravital imaging revealed clusters of largely immotile CX3CR1+ monocytes/macrophages in regressing plaques that had been recruited from the periphery. We observed a progressive decrease in CX3CR1+ monocytic cells in regressing plaques and a decrease in CCR2+ positron emission tomography signal during 4 months. CONCLUSIONS: Cervical transplantation of atherosclerotic mouse aortic arches represents a novel experimental tool to investigate cellular mechanisms that contribute to the remodeling of atherosclerotic plaques. PMID- 29567680 TI - Chronic Intake of the Selective Serotonin Reuptake Inhibitor Fluoxetine Enhances Atherosclerosis. AB - OBJECTIVE: Cardiovascular diseases and depression are the leading causes of disability in Western countries. Clinical data on potential cardiovascular effects of serotonin reuptake inhibitors (SSRIs), the most commonly used antidepressant drugs, are controversial. In addition to blocking serotonin reuptake transporter in the brain, SSRIs deplete the major peripheral serotonin (5-hydroxytryptamine [5-HT]) storage by inhibiting serotonin reuptake transporter mediated uptake in platelets. In this study, we aimed to investigate the effect of chronic SSRI intake on the development of atherosclerosis. APPROACH AND RESULTS: Treatment of apolipoprotein E-deficient mice with the SSRI fluoxetine for 2, 4, or 16 weeks increased atherosclerotic lesion formation, with most pronounced effect during early plaque development. Intravital microscopy of carotid arteries revealed enhanced myeloid cell adhesion on fluoxetine treatment. Mechanistically, we found that fluoxetine augmented vascular permeability and increased chemokine-induced integrin-binding activity of circulating leukocytes. In vitro stimulation of murine blood demonstrated that fluoxetine, but not 5-HT, could directly promote beta1 and beta2 integrin activation provided C-C motif chemokine ligand 5 was also present. Similar effects were observed with the SSRI escitalopram. Enhanced C-C motif chemokine ligand 5-induced integrin activation by fluoxetine was also confirmed in a human neutrophil-like cell line. In contrast to the proatherogenic properties of fluoxetine, pharmacological inhibition of the peripheral 5-HT synthesizing enzyme tryptophan hydroxylase 1 did not promote atherosclerosis, suggesting that the proatherogenic effect of fluoxetine occurs independent of peripheral 5-HT depletion. CONCLUSIONS: SSRI intake may promote atherosclerosis and therefore potentially increase the risk for acute cardiovascular events by a mechanism that is independent of 5-HT depletion. PMID- 29567679 TI - Genetic Factors Explain a Major Fraction of the 50% Lower Lipoprotein(a) Concentrations in Finns. AB - OBJECTIVE: Lp(a) (lipoprotein(a)) concentrations are widely genetically determined by the LPA isoforms and show 5-fold interpopulation differences. Two- to 3-fold differences have been reported even within Europe. Finns represent a distinctive population isolate within Europe and have been repeatedly reported to present lower Lp(a) concentrations than Central Europeans. The significance of this finding was unclear for a long time because of the difficult comparability of Lp(a) assays. Recently, a large standardized study in >50 000 individuals from 7 European populations confirmed this observation but could not provide insights into the causes. APPROACH AND RESULTS: We investigated Lp(a) concentrations, LPA isoforms, and genotypes of established genetic variants affecting Lp(a) concentrations (LPA variants, APOE isoforms, and PCSK9 R46L) in the Finnish YFS (Cardiovascular Risk in Young Finns Study) population (n=2281) and 3 Non-Finnish Central European populations (n=10 003). We observed ~50% lower Lp(a) concentrations in Finns. The isoform distribution was shifted toward longer isoforms, and the percentage of low-molecular-weight isoform carriers was reduced. Most interestingly, however, Lp(a) was reduced in each single-isoform group. In contrast to the known inverse relationship between LPA isoforms and Lp(a) concentrations, especially very short isoforms presented unexpectedly low Lp(a) concentrations in Finns. The investigated genetic variants, as well as age, sex, and renal function, explained 71.8% of the observed population differences. CONCLUSIONS: The population differences in Lp(a) concentrations between Finnish and Central European populations originate not only from a different LPA isoform distribution but suggest the existence of novel functional variation in the small isoform range.

PMID- 29567681 TI - Classical Pathway of Complement Activation: Longitudinal Associations of C1q and C1-INH With Cardiovascular Outcomes: The CODAM Study (Cohort on Diabetes and Atherosclerosis Maastricht)-Brief Report. AB - OBJECTIVE: The classical complement pathway has been assigned both protective and pathological effects in cardiovascular disease (CVD), but human data are lacking. We determined the associations of the pattern recognition factor C1q and the regulator C1-INH (C1-inhibitor) with incident CVD, carotid intima-media thickness, endothelial dysfunction, and low-grade inflammation. APPROACH AND RESULTS: Baseline concentrations of C1q and C1-INH were measured in the CODAM study (Cohort on Diabetes and Atherosclerosis Maastricht; n=574; 61% men; age, 60+/-7 years). The 7-year incidence of CVD in participants free of CVD at baseline was evaluated using logistic regression analyses (n=342; 73 cases). The lowest incidence of CVD was observed in the middle tertile of C1q (Tlow compared with Tmiddle: odds ratio, 2.38 [95% confidence interval, 1.14-4.95]; Thigh compared with Tmiddle: odds ratio, 1.96 [95% confidence interval, 0.94-4.07]). C1 INH was not associated with CVD. During the 7-year follow-up period, C1q and C1 INH were not, or inconsistently, associated with carotid intima-media thickness or with biomarker scores reflecting endothelial dysfunction and low-grade inflammation. CONCLUSIONS: Our results suggest a nonlinear association between C1q and incident CVD. This supports the concept that early steps in classical pathway activation may have both protective and pathological effects on human CVD.

PMID- 29567705 TI - Cancer immunotherapy using checkpoint blockade. AB - The release of negative regulators of immune activation (immune checkpoints) that limit antitumor responses has resulted in unprecedented rates of long-lasting tumor responses in patients with a variety of cancers. This can be achieved by antibodies blocking the cytotoxic T lymphocyte-associated protein 4 (CTLA-4) or the programmed cell death 1 (PD-1) pathway, either alone or in combination. The main premise for inducing an immune response is the preexistence of antitumor T cells that were limited by specific immune checkpoints. Most patients who have tumor responses maintain long-lasting disease control, yet one-third of patients relapse. Mechanisms of acquired resistance are currently poorly understood, but evidence points to alterations that converge on the antigen presentation and interferon-gamma signaling pathways. New-generation combinatorial therapies may overcome resistance mechanisms to immune checkpoint therapy. PMID- 29567706 TI - Personalized vaccines for cancer immunotherapy. AB - Cancer is characterized by an accumulation of genetic alterations. Somatic mutations can generate cancer-specific neoepitopes that are recognized by autologous T cells as foreign and constitute ideal cancer vaccine targets. Every tumor has its own unique composition of mutations, with only a small fraction shared between patients. Technological advances in genomics, data science, and cancer immunotherapy now enable the rapid mapping of the mutations within a genome, rational selection of vaccine targets, and on-demand production of a therapy customized to a patient's individual tumor. First-in-human clinical trials of personalized cancer vaccines have shown the feasibility, safety, and immunotherapeutic activity of targeting individual tumor mutation signatures. With vaccination development being promoted by emerging innovations of the digital age, vaccinating a patient with individual tumor mutations may become the first truly personalized treatment for cancer.

AB - Adoptive T cell transfer (ACT) is a new area of transfusion medicine involving the infusion of lymphocytes to mediate antitumor, antiviral, or anti-inflammatory effects. The field has rapidly advanced from a promising form of immuno-oncology in preclinical models to the recent commercial approvals of chimeric antigen receptor (CAR) T cells to treat leukemia and lymphoma. This Review describes opportunities and challenges for entering mainstream oncology that presently face the CAR T field, with a focus on the challenges that have emerged over the past several years. PMID- 29567708 TI - The microbiome in cancer immunotherapy: Diagnostic tools and therapeutic strategies. AB - The fine line between human health and disease can be driven by the interplay between host and microbial factors. This "metagenome" regulates cancer initiation, progression, and response to therapies. Besides the capacity of distinct microbial species to modulate the pharmacodynamics of chemotherapeutic drugs, symbiosis between epithelial barriers and their microbial ecosystems has a major impact on the local and distant immune system, markedly influencing clinical outcome in cancer patients. Efficacy of cancer immunotherapy with immune checkpoint antibodies can be diminished with administration of antibiotics, and superior efficacy is observed with the presence of specific gut microbes. Future strategies of precision medicine will likely rely on novel diagnostic and therapeutic tools with which to identify and correct defects in the microbiome that compromise therapeutic efficacy. PMID- 29567709 TI - Bioinspired spring origami. AB - Origami enables folding of objects into a variety of shapes in arts, engineering, and biological systems. In contrast to well-known paper-folded objects, the wing of the earwig has an exquisite natural folding system that cannot be sufficiently described by current origami models. Such an unusual biological system displays incompatible folding patterns, remains open by a bistable locking mechanism during flight, and self-folds rapidly without muscular actuation. We show that these notable functionalities arise from the protein-rich joints of the earwig wing, which work as extensional and rotational springs between facets. Inspired by this biological wing, we establish a spring origami model that broadens the folding design space of traditional origami and allows for the fabrication of precisely tunable, four-dimensional-printed objects with programmable bioinspired morphing functionalities. PMID- 29567710 TI - A nonconjugated radical polymer glass with high electrical conductivity. AB - Solid-state conducting polymers usually have highly conjugated macromolecular backbones and require intentional doping in order to achieve high electrical conductivities. Conversely, single-component, charge-neutral macromolecules could be synthetically simpler and have improved processibility and ambient stability. We show that poly(4-glycidyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl), a nonconjugated radical polymer with a subambient glass transition temperature, underwent rapid solid-state charge transfer reactions and had an electrical conductivity of up to 28 siemens per meter over channel lengths up to 0.6 micrometers. The charge transport through the radical polymer film was enabled with thermal annealing at 80 degrees C, which allowed for the formation of a percolating network of open-shell sites in electronic communication with one another. The electrical conductivity was not enhanced by intentional doping, and thin films of this material showed high optical transparency. PMID- 29567711 TI - Early life experience drives structural variation of neural genomes in mice. AB - The brain is a genomic mosaic owing to somatic mutations that arise throughout development. Mobile genetic elements, including retrotransposons, are one source of somatic mosaicism in the brain. Retrotransposition may represent a form of plasticity in response to experience. Here, we use droplet digital polymerase chain reaction to show that natural variations in maternal care mediate the mobilization of long interspersed nuclear element-1 (LINE-1 or L1) retrotransposons in the hippocampus of the mouse brain. Increasing the amount of maternal care blocks the accumulation of L1. Maternal care also alters DNA methylation at YY1 binding sites implicated in L1 activation and affects expression of the de novo methyltransferase DNMT3a. Our observations indicate that early life experience drives somatic variation in the genome via L1 retrotransposons. PMID- 29567712 TI - A single fungal MAP kinase controls plant cell-to-cell invasion by the rice blast fungus. AB - Blast disease destroys up to 30% of the rice crop annually and threatens global food security. The blast fungus Magnaporthe oryzae invades plant tissue with hyphae that proliferate and grow from cell to cell, often through pit fields, where plasmodesmata cluster. We showed that chemical genetic inhibition of a single fungal mitogen-activated protein (MAP) kinase, Pmk1, prevents M. oryzae from infecting adjacent plant cells, leaving the fungus trapped within a single plant cell. Pmk1 regulates expression of secreted fungal effector proteins implicated in suppression of host immune defenses, preventing reactive oxygen species generation and excessive callose deposition at plasmodesmata. Furthermore, Pmk1 controls the hyphal constriction required for fungal growth from one rice cell to the neighboring cell, enabling host tissue colonization and blast disease. PMID- 29567714 TI - Lymph node blood vessels provide exit routes for metastatic tumor cell dissemination in mice. AB - During metastasis, malignant cells escape the primary tumor, intravasate lymphatic vessels, and reach draining sentinel lymph nodes before they colonize distant organs via the blood circulation. Although lymph node metastasis in cancer patients correlates with poor prognosis, evidence is lacking as to whether and how tumor cells enter the bloodstream via lymph nodes. To investigate this question, we delivered carcinoma cells into the lymph nodes of mice by microinfusing the cells into afferent lymphatic vessels. We found that tumor cells rapidly infiltrated the lymph node parenchyma, invaded blood vessels, and seeded lung metastases without involvement of the thoracic duct. These results suggest that the lymph node blood vessels can serve as an exit route for systemic dissemination of cancer cells in experimental mouse models. Whether this form of tumor cell spreading occurs in cancer patients remains to be determined. PMID- 29567713 TI - Lymph node metastases can invade local blood vessels, exit the node, and colonize distant organs in mice. AB - Lymph node metastases in cancer patients are associated with tumor aggressiveness, poorer prognoses, and the recommendation for systemic therapy. Whether cancer cells in lymph nodes can seed distant metastases has been a subject of considerable debate. We studied mice implanted with cancer cells (mammary carcinoma, squamous cell carcinoma, or melanoma) expressing the photoconvertible protein Dendra2. This technology allowed us to selectively photoconvert metastatic cells in the lymph node and trace their fate. We found that a fraction of these cells invaded lymph node blood vessels, entered the blood circulation, and colonized the lung. Thus, in mouse models, lymph node metastases can be a source of cancer cells for distant metastases. Whether this mode of dissemination occurs in cancer patients remains to be determined. PMID- 29567715 TI - The biosynthesis of methanobactin. AB - Metal homeostasis poses a major challenge to microbes, which must acquire scarce elements for core metabolic processes. Methanobactin, an extensively modified copper-chelating peptide, was one of the earliest natural products shown to enable microbial acquisition of a metal other than iron. We describe the core biosynthetic machinery responsible for the characteristic posttranslational modifications that grant methanobactin its specificity and affinity for copper. A heterodimer comprising MbnB, a DUF692 family iron enzyme, and MbnC, a protein from a previously unknown family, performs a dioxygen-dependent four-electron oxidation of the precursor peptide (MbnA) to install an oxazolone and an adjacent thioamide, the characteristic methanobactin bidentate copper ligands. MbnB and MbnC homologs are encoded together and separately in many bacterial genomes, suggesting functions beyond their roles in methanobactin biosynthesis. PMID- 29567716 TI - Locally translated mTOR controls axonal local translation in nerve injury. AB - How is protein synthesis initiated locally in neurons? We found that mTOR (mechanistic target of rapamycin) was activated and then up-regulated in injured axons, owing to local translation of mTOR messenger RNA (mRNA). This mRNA was transported into axons by the cell size-regulating RNA-binding protein nucleolin. Furthermore, mTOR controlled local translation in injured axons. This included regulation of its own translation and that of retrograde injury signaling molecules such as importin beta1 and STAT3 (signal transducer and activator of transcription 3). Deletion of the mTOR 3' untranslated region (3'UTR) in mice reduced mTOR in axons and decreased local translation after nerve injury. Both pharmacological inhibition of mTOR in axons and deletion of the mTOR 3'UTR decreased proprioceptive neuronal survival after nerve injury. Thus, mRNA localization enables spatiotemporal control of mTOR pathways regulating local translation and long-range intracellular signaling. PMID- 29567718 TI - ERJ March Podcast: World TB Day.

PMID- 29567761 TI - SCIL-STROKE (Subcutaneous Interleukin-1 Receptor Antagonist in Ischemic Stroke): A Randomized Controlled Phase 2 Trial. AB - BACKGROUND AND PURPOSE: The proinflammatory cytokine IL-1 (interleukin-1) has a deleterious role in cerebral ischemia, which is attenuated by IL-1 receptor antagonist (IL-1Ra). IL-1 induces peripheral inflammatory mediators, such as interleukin-6, which are associated with worse prognosis after ischemic stroke. We investigated whether subcutaneous IL-1Ra reduces the peripheral inflammatory response in acute ischemic stroke. METHODS: SCIL-STROKE (Subcutaneous Interleukin 1 Receptor Antagonist in Ischemic Stroke) was a single-center, double-blind, randomized, placebo-controlled phase 2 trial of subcutaneous IL-1Ra (100 mg administered twice daily for 3 days) in patients presenting within 5 hours of ischemic stroke onset. Randomization was stratified for baseline National Institutes of Health Stroke Scale score and thrombolysis. Measurement of plasma interleukin-6 and other peripheral inflammatory markers was undertaken at 5 time points. The primary outcome was difference in concentration of log(interleukin-6) as area under the curve to day 3. Secondary outcomes included exploratory effect of IL-1Ra on 3-month outcome with the modified Rankin Scale. RESULTS: We recruited 80 patients (mean age, 72 years; median National Institutes of Health Stroke Scale, 12) of whom 73% received intravenous thrombolysis with alteplase. IL-1Ra significantly reduced plasma interleukin-6 (P<0.001) and plasma C-reactive protein (P<0.001). IL-1Ra was well tolerated with no safety concerns. Allocation to IL-1Ra was not associated with a favorable outcome on modified Rankin Scale: odds ratio (95% confidence interval)=0.67 (0.29-1.52), P=0.34. Exploratory mediation analysis suggested that IL-1Ra improved clinical outcome by reducing inflammation, but there was a statistically significant, alternative mechanism countering this benefit. CONCLUSIONS: IL-1Ra reduced plasma inflammatory markers which are known to be associated with worse clinical outcome in ischemic stroke. Subcutaneous IL-1Ra is safe and well tolerated. Further experimental studies are required to investigate efficacy and possible interactions of IL-1Ra with thrombolysis. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.

AB - BACKGROUND AND PURPOSE: Deficiencies in stroke preparedness cause major delays to stroke thrombolysis, particularly among economically disadvantaged minorities. We evaluated the effectiveness of a stroke preparedness intervention delivered to preadolescent urban public school children on the stroke knowledge/preparedness of their parents. METHODS: We recruited 3070 fourth through sixth graders and 1144 parents from 22 schools into a cluster randomized trial with schools randomized to the HHS (Hip-Hop Stroke) intervention or attentional control (nutrition classes). HHS is a 3-hour culturally tailored, theory-based, multimedia stroke literacy intervention targeting school children, which systematically empowers children to share stroke information with parents. Our main outcome measures were stroke knowledge/preparedness of children and parents using validated surrogates. RESULTS: Among children, it was estimated that 1% (95% confidence interval [CI], 0%-1%) of controls and 2% (95% CI, 1%-4%; P=0.09) of the intervention group demonstrated optimal stroke preparedness (perfect scores on the knowledge/preparedness test) at baseline, increasing to 57% (95% CI, 44%-69%) immediately after the program in the intervention group compared with 1% (95% CI, 0%-1%; P<0.001) among controls. At 3-month follow-up, 24% (95% CI, 15%-33%) of the intervention group retained optimal preparedness, compared with 2% (95% CI, 0%-3%; P<0.001) of controls. Only 3% (95% CI, 2%-4%) of parents in the intervention group could identify all 4 letters of the stroke FAST (Facial droop, Arm weakness, Speech disturbance, Time to call 911) acronym at baseline, increasing to 20% at immediate post-test (95% CI, 16%-24%) and 17% at 3-month delayed post-test (95% CI, 13%-21%; P=0.0062), with no significant changes (3% identification) among controls. Four children, all in the intervention group, called 911 for real-life stroke symptoms, in 1 case overruling a parent's wait and-see approach. CONCLUSIONS: HHS is an effective, intergenerational model for increasing stroke preparedness among economically disadvantaged minorities. CLINICAL TRIAL REGISTRATION: URL: https://clinicaltrials.gov.

AB - BACKGROUND AND PURPOSE: Insights into evolution of cerebral small vessel disease on neuroimaging might advance knowledge of the natural disease course. Data on evolution of sporadic symptomatic lacunar infarcts are limited. We investigated long-term changes of symptomatic lacunar infarcts and surrounding white matter on structural magnetic resonance imaging. METHODS: From 2 nonoverlapping, single center, prospective observational stroke studies, we selected patients presenting with lacunar stroke symptoms with a recent small subcortical (lacunar) infarct on baseline structural magnetic resonance imaging and with follow-up magnetic resonance imaging available at 1 to 5 years. We assessed changes in imaging characteristics of symptomatic lacunar infarcts and surrounding white matter. RESULTS: We included 79 patients of whom 32 (41%) had complete and 40 (51%) had partial cavitation of the index lesion at median follow-up of 403 (range, 315 1781) days. In 42 of 79 (53%) patients, we observed a new white matter hyperintensity adjacent to the index infarct, either superior (white matter hyperintensity cap, n=17), inferior (white matter hyperintensity track, n=13), or both (n=12). CONCLUSIONS: Half of the sporadic symptomatic lacunar infarcts developed secondary changes in superior and inferior white matter. These white matter hyperintensity caps and tracks may reflect another aspect of cerebral small vessel-related disease progression. The clinical and prognostic values remain to be determined. PMID- 29567764 TI - Moderate-to-Vigorous Physical Activity and All-Cause Mortality: Do Bouts Matter? AB - BACKGROUND: The 2008 Physical Activity Guidelines for Americans recommends that adults accumulate moderate-to-vigorous physical activity (MVPA) in bouts of >=10 minutes for substantial health benefits. To what extent the same amount of MVPA accumulated in bouts versus sporadically reduces mortality risk remains unclear. METHODS AND RESULTS: We analyzed data from the National Health and Nutrition Examination Survey 2003-2006 and death records available through 2011 (follow-up period of ~6.6 years; 700 deaths) to examine the associations between objectively measured physical activity accumulated with and without a bout criteria and all cause mortality in a representative sample of US adults 40 years and older (n=4840). Physical activity data were processed to generate minutes per day of total and bouted MVPA. Bouted MVPA was defined as MVPA accumulated in bouts of a minimum duration of either 5 or 10 minutes allowing for 1- to 2-minute interruptions. Hazard ratios for all-cause mortality associated with total and bouted MVPA were similar and ranged from 0.24 for the third quartile of total to 0.44 for the second quartile of 10-minute bouts. The examination of jointly classified quartiles of total MVPA and tertiles of proportion of bouted activity revealed that greater amounts of bouted MVPA did not result in additional risk reductions for mortality. CONCLUSIONS: These results provide evidence that mortality risk reductions associated with MVPA are independent of how activity is accumulated and can impact the development of physical activity guidelines and inform clinical practice.

PMID- 29567766 TI - Pivotal role of NAMPT in the switch of melanoma cells toward an invasive and drug resistant phenotype. AB - In BRAFV600E melanoma cells, a global metabolomic analysis discloses a decrease in nicotinamide adenine dinucleotide (NAD+) levels upon PLX4032 treatment that is conveyed by a STAT5 inhibition and a transcriptional regulation of the nicotinamide phosphoribosyltransferase (NAMPT) gene. NAMPT inhibition decreases melanoma cell proliferation both in vitro and in vivo, while forced NAMPT expression renders melanoma cells resistant to PLX4032. NAMPT expression induces transcriptomic and epigenetic reshufflings that steer melanoma cells toward an invasive phenotype associated with resistance to targeted therapies and immunotherapies. Therefore, NAMPT, the key enzyme in the NAD+ salvage pathway, appears as a rational target in targeted therapy-resistant melanoma cells and a key player in phenotypic plasticity of melanoma cells.

PMID- 29567768 TI - Highly sensitive MYD88L265P mutation detection by droplet digital polymerase chain reaction in Waldenstrom macroglobulinemia. AB - We here describe a novel method for MYD88L265P mutation detection and minimal residual disease monitoring in Waldenstrom macroglobulinemia, by droplet digital polymerase chain reaction, in bone marrow and peripheral blood cells, as well as in circulating cell-free DNA. Our method shows a sensitivity of 5.00*10-5, which is far superior to the widely used allele-specific polymerase chain reaction (1.00*10-3). Overall, 291 unsorted samples from 148 patients (133 with Waldenstrom macroglobulinemia, 11 with IgG lymphoplasmacytic lymphoma and 4 with IgM monoclonal gammopathy of undetermined significance) were analyzed: 194 were baseline samples and 97 were followup samples. One hundred and twenty-two of 128 (95.3%) bone marrow and 47/66 (71.2%) baseline peripheral blood samples scored positive for MYD88L265P To investigate whether MYD88L265P detection by droplet digital polymerase chain reaction could be used for minimal residual disease monitoring, mutation levels were compared with IGH-based minimal residual disease analysis in 10 patients, and was found to be as informative as the classical, standardized, but not yet validated in Waldenstrom macroglobulinemia, IGH-based minimal residual disease assay (r2=0.64). Finally, MYD88L265P detection by droplet digital polymerase chain reaction on plasma circulating tumor DNA from 60 patients showed a good correlation with bone marrow findings (bone marrow median mutational value 1.92*10-2, plasma circulating tumor DNA value: 1.4*10-2, peripheral blood value: 1.03*10-3). This study indicates that droplet digital polymerase chain reaction assay of MYD88L265P is a feasible and sensitive tool for mutation screening and minimal residual disease monitoring in Waldenstrom macroglobulinemia. Both unsorted bone marrow and peripheral blood samples can be reliably tested, as can circulating tumor DNA, which represents an attractive, less invasive alternative to bone marrow for MYD88L265P detection. PMID- 29567771 TI - Gene expression profiling reveals a close relationship between follicular lymphoma grade 3A and 3B, but distinct profiles of follicular lymphoma grade 1 and 2. AB - A linear progression model of follicular lymphomas (FL) FL1, FL2 and FL3A has been favored, since FL3A often co-exist with an FL1/2 component. FL3B, in contrast, is thought to be more closely related to diffuse large B-cell lymphoma (DLBCL), and both are often simultaneously present in one tumor (DLBCL/FL3B). To obtain more detailed insights into follicular lymphoma progression, a comprehensive analysis of a well-defined set of FL1/2 (n=22), FL3A (n=16), FL3B (n=6), DLBCL/FL3B (n=9), and germinal center B-cell-type diffuse large B-cell lymphoma (n=45) was undertaken using gene expression profiling, immunohistochemical stainings and genetic analyses by fluorescence in situ hybridization. While immunohistochemical (CD10, IRF4/MUM1, Ki67, BCL2, BCL6) and genetic profiles (translocations of BCL2, BCL6 and MYC) delineate FL1-3A from FL3B and DLBCL/FL3B, significant differences were observed between FL1/2 and FL3A upon gene expression profiling. Interestingly, FL3B turned out to be closely related to FL3A, not categorizing within a separate gene expression cluster, and both FL3A and FL3B showed overlapping profiles in between FL1/2 and diffuse large B-cell lymphoma. Finally, based upon their gene expression pattern, DLBCL/FL3B represent a composite form of FL3B and DLBCL, with the majority of samples more closely resembling the latter. The fact that gene expression profiling clearly separated FL1/2 from both FL3A and FL3B suggests a closer biological relationship between the latter. This notion, however, is in contrast to immunohistochemical and genetic profiles of the different histological FL subtypes that point to a closer relationship between FL1/2 and FL3A, and separates them from FL3B. PMID- 29567770 TI - Fit alphabeta T-cell receptor suppresses leukemogenesis of Pten-deficient thymocytes. AB - Signaling through the alphabetaT cell receptor (TCR) is a crucial determinant of T-cell fate and can induce two opposite outcomes during thymocyte development: cell death or survival and differentiation. To date, the role played by T-cell receptor in the oncogenic transformation of developing T cells remains unclear. Here we show that human primary T-cell acute lymphoblastic leukemias expressing an alphabetaT cell receptor are frequently deficient for phosphatase and tensin homolog protein (PTEN), and fail to respond strongly to T-cell receptor activation. Using Pten-deficient T-cell acute lymphoblastic leukemia mouse models, we confirm that T-cell receptor signaling is involved in leukemogenesis. We show that abrogation of T-cell receptor expression accelerated tumor onset, while enforced expression of a fit transgenic T-cell receptor led to the development of T-cell receptor-negative lymphoma and delayed tumorigenesis. We further demonstrate that pre-tumoral Pten-deficient thymocytes harboring fit T cell receptors undergo early clonal deletion, thus preventing their malignant transformation, while cells with unfit T-cell receptors that should normally be deleted during positive selection, pass selection and develop T-cell acute lymphoblastic leukemias. Altogether, our data show that fit T-cell receptor signaling suppresses tumor development mediated by Pten loss-of-function and point towards a role of Pten in positive selection.

PMID- 29567773 TI - JAK2V617F-bearing vascular niche enhances malignant hematopoietic regeneration following radiation injury. AB - Myeloproliferative neoplasms are clonal stem cell disorders characterized by hematopoietic stem/progenitor cell expansion. The acquired kinase mutation JAK2V617F plays a central role in these disorders. Abnormalities of the marrow microenvironment are beginning to be recognized as an important factor in the development of myeloproliferative neoplasms. Endothelial cells are an essential component of the hematopoietic vascular niche. Endothelial cells carrying the JAK2V617F mutation can be detected in patients with myeloproliferative neoplasms, suggesting that the mutant vascular niche is involved in the pathogenesis of these disorders. Here, using a transgenic mouse expressing JAK2V617F specifically in all hematopoietic cells (including hematopoietic stem/progenitor cells) and endothelial cells, we show that the JAK2V617F-mutant hematopoietic stem/progenitor cells are relatively protected by the JAK2V617F-bearing vascular niche from an otherwise lethal dose of irradiation during conditioning for stem cell transplantation. Gene expression analysis revealed that chemokine (C-X-C motif) ligand 12, epidermal growth factor, and pleiotrophin are up-regulated in irradiated JAK2V617F-bearing endothelial cells compared to wild-type cells. Our findings suggest that the mutant vascular niche may contribute to the high incidence of disease relapse in patients with myeloproliferative neoplasms following allogeneic stem cell transplantation, the only curative treatment for these disorders.

PMID- 29567775 TI - Low-count monoclonal B-cell lymphocytosis persists after seven years of follow up and is associated with a poorer outcome. AB - Low-count monoclonal B-cell lymphocytosis is defined by the presence of very low numbers of circulating clonal B cells, usually phenotypically similar to chronic lymphocytic leukemia cells, whose biological and clinical significance remains elusive. Herein, we re-evaluated 65/91 low-count monoclonal B-cell lymphocytosis cases (54 chronic lymphocytic leukemia-like and 11 non-chronic lymphocytic leukemia-like) followed-up for a median of seven years, using high-sensitivity flow cytometry and interphase fluorescence in situ hybridization. Overall, the clone size significantly increased in 69% of low-count monoclonal B-cell lymphocytosis cases, but only one subject progressed to high-count monoclonal B cell lymphocytosis. In parallel, the frequency of cytogenetic alterations increased over time (32% vs 61% of cases, respectively). The absolute number of the major T-cell and natural killer cell populations also increased, but only among chronic lymphocytic leukemia-like cases with increased clone size vs age- and sex-matched controls. Although progression to chronic lymphocytic leukemia was not observed, the overall survival of low-count monoclonal B-cell lymphocytosis individuals was significantly reduced vs non-monoclonal B-cell lymphocytosis controls (P=0.03) plus the general population from the same region (P<=0.001), particularly among females (P=0.01); infection and cancer were the main causes of death in low-count monoclonal B-cell lymphocytosis. In summary, despite the fact that mid-term progression from low-count monoclonal B-cell lymphocytosis to high-count monoclonal B-cell lymphocytosis and chronic lymphocytic leukemia appears to be unlikely, these clones persist at increased numbers, usually carrying more genetic alterations, and might thus be a marker of an impaired immune system indirectly associated with a poorer outcome, particularly among females.

AB - Although inhibitors of bromodomain and extra terminal domain (BET) proteins show promising clinical activity in different hematologic malignancies, a systematic analysis of the consequences of pharmacological BET inhibition on healthy hematopoietic (stem) cells is urgently needed. We found that JQ1 treatment decreases the numbers of pre-, immature and mature B cells while numbers of early pro-B cells remain constant. In addition, JQ1 treatment increases apoptosis in T cells, all together leading to reduced cellularity in thymus, bone marrow and spleen. Furthermore, JQ1 induces proliferation of long-term hematopoietic stem cells, thereby increasing stem cell numbers. Due to increased numbers, JQ1 treated hematopoietic stem cells engrafted better after stem cell transplantation and repopulated the hematopoietic system significantly faster after sublethal myeloablation. As quantity and functionality of hematopoietic stem cells determine the duration of life-threatening myelosuppression, BET inhibition might benefit patients in myelosuppressive conditions.

PMID- 29567779 TI - Mass spectrometry-assisted identification of ADAMTS13-derived peptides presented on HLA-DR and HLA-DQ. AB - Formation of microthrombi is a hallmark of acquired thrombotic thrombocytopenic purpura. These microthrombi originate from insufficient processing of ultra large von Willebrand factor multimers by ADAMTS13 due to the development of anti ADAMTS13 autoantibodies. Several studies have identified the major histocompatibility complex class II alleles HLA-DRB1*11, HLA-DQB1*03 and HLA DQB1*02:02 as risk factors for acquired thrombotic thrombocytopenic purpura development. Previous research in our department indicated that ADAMTS13 CUB2 domain-derived peptides FINVAPHAR and LIRDTHSLR are presented on HLA-DRB1*11 and HLA-DRB1*03, respectively. Here, we describe the repertoire of ADAMTS13 peptides presented on HLA-DQ. In parallel, the repertoire of ADAMTS13-derived peptides presented on HLA-DR was monitored. Using HLA-DR- and HLA-DQ-specific antibodies, we purified HLA/peptide complexes from ADAMTS13-pulsed monocyte-derived dendritic cells. Using this approach, we identified ADAMTS13-derived peptides presented on HLA-DR for all 9 samples analyzed; ADAMTS13-derived peptides presented on HLA-DQ were identified in 4 out of 9 samples. We were able to confirm the presentation of the CUB2 domain-derived peptides FINVAPHAR and LIRDTHSLR on HLA-DR. In total, 12 different core-peptide sequences were identified on HLA-DR and 8 on HLA-DQ. For HLA-DR11, several potential new core-peptides were found; 4 novel core peptides were exclusively identified on HLA-DQ. Furthermore, an in silico analysis was performed using the EpiMatrix and JanusMatrix tools to evaluate the eluted peptides, in the context of HLA-DR, for putative effector or regulatory T cell responses at the population level. The results from this study provide a basis for the identification of immuno-dominant epitopes on ADAMTS13 involved in the onset of acquired thrombotic thrombocytopenic purpura.

PMID- 29567781 TI - A novel regimen for relapsed/refractory adult acute myeloid leukemia using a KMT2A partial tandem duplication targeted therapy: results of phase 1 study NCI 8485. AB - KMT2A partial tandem duplication occurs in approximately 5-10% of patients with acute myeloid leukemia and is associated with adverse prognosis. KMT2A wild type is epigenetically silenced in KMT2A partial tandem duplication; re-expression can be induced with DNA methyltransferase and/or histone deacetylase inhibitors in vitro, sensitizing myeloid blasts to chemotherapy. We hypothesized that epigenetic silencing of KMT2A wildtype contributes to KMT2A partial tandem duplication-associated leukemogenesis and pharmacologic re-expression activates apoptotic mechanisms important for chemoresponse. We developed a regimen for this unique molecular subset, but due to relatively low frequency of KMT2A partial tandem duplication, this dose finding study was conducted in relapsed/refractory disease regardless of molecular subtype. Seventeen adults (< age 60) with relapsed/refractory acute myeloid leukemia were treated on study. Patients received decitabine 20 milligrams/meter2 daily on days 1-10 and vorinostat 400 milligrams daily on days 5-10. Cytarabine was dose-escalated from 1.5 grams/meter2 every 12 hours to 3 grams/meter2 every 12 hours on days 12, 14 and 16. Two patients experienced dose limiting toxicities at dose level 1 due to prolonged myelosuppression. However, as both patients achieved complete remission after Day 42, the protocol was amended to adjust the definition of hematologic dose limiting toxicity. No further dose limiting toxicities were found. Six of 17 patients achieved complete remission including 2 of 4 patients with KMT2A partial tandem duplication. Combination therapy with decitabine, vorinostat and cytarabine was tolerated in younger relapsed/refractory acute myeloid leukemia and should be explored further focusing on the KMT2A partial tandem duplication subset.

PMID- 29567784 TI - Treatment to suppression of focal lesions on positron emission tomography computed tomography is a therapeutic goal in newly diagnosed multiple myeloma. AB - Fluorine-18 fluorodeoxyglucose positron emission tomography with computed tomography attenuation correction (PET-CT) in myeloma can detect and enumerate focal lesions by the quantitative characterization of metabolic activity. The aim of this study was to determine the prognostic significance of the suppression of PET-CT activity at a number of time points post therapy initiation: day 7, post induction, post transplant, and at maintenance therapy. As part of the TT4-6 trial series, 596 patients underwent baseline PET-CT and were evaluated serially during their disease course using peak standardized uptake values above background red marrow signal. We demonstrate that the presence of more than 3 focal lesions at presentation identifies a group of patients with an adverse progression-free survival and overall survival. At day 7 of therapy, patients with complete focal lesion signal suppression revert to the same prognosis as those with no lesions at diagnosis. At later time points, the continued suppression of signal remains prognostically important. We conclude that for newly diagnosed patients with focal lesions, treatment until these lesions are suppressed is an important therapeutic goal as the prognosis of these patients is the same as those without lesions at diagnosis.

PMID- 29567785 TI - DNA polymerase nu gene expression influences fludarabine resistance in chronic lymphocytic leukemia independently of p53 status. AB - Alteration in the DNA replication, repair or recombination processes is a highly relevant mechanism of genomic instability. Despite genomic aberrations manifested in hematologic malignancies, such a defect as a source of biomarkers has been underexplored. Here, we investigated the prognostic value of expression of 82 genes involved in DNA replication-repair-recombination in a series of 99 patients with chronic lymphocytic leukemia without detectable 17p deletion or TP53 mutation. We found that expression of the POLN gene, encoding the specialized DNA polymerase nu (Pol nu) correlates with time to relapse after first-line therapy with fludarabine. Moreover, we found that POLN was the only gene up-regulated in primary patients' lymphocytes when exposed in vitro to proliferative and pro survival stimuli. By using two cell lines that were sequentially established from the same patient during the course of the disease and Pol nu knockout mouse embryonic fibroblasts, we reveal that high relative POLN expression is important for DNA synthesis and cell survival upon fludarabine treatment. These findings suggest that Pol nu could influence therapeutic resistance in chronic lymphocytic leukemia.

Aim of this retrospective case series is to report 1-year outcomes of a modified surgical technique entailing full tendon transposition of lateral rectus to medial rectus augmented with posterior fixation sutures in four patients with complete third nerve palsy. All four cases showed significant improvement of vertical and horizontal deviation with long-term stability of correction. Choice of route of full tendon augmented transposition of lateral rectus to medial rectus can aid in achieving good correction of the vertical misalignment in addition to horizontal correction.

AB - PURPOSE: To determine the prevalence of congenitally abnormal disc (all anomalies) in an adult population in southern India. METHODS: Subjects aged >=40 years (n=6013) underwent a complete ophthalmic examination. Optic disc anomalies were diagnosed according to the definitions given in the article. RESULTS: Optic disc anomalies were found in 81 eyes of 66 (1.1%, 95% CIs 0.00834 to 0.01361) patients. The prevalence of each anomaly in the descending order was peripapillary myelinated nerve fibre (0.28%), epipapillary glial tissue on the optic disc (0.28%), peripapillary vascular loops (0.16%), tilted disc (0.09%), optic disc coloboma (0.08%), optic nerve hypoplasia (0.04%), optic disc pit (0.04%), optic disc pigmentation (0.03%), optic nerve head drusen (0.03%), Bergmeister's papilla (0.03%), optic disc pit and coloboma (0.01%).

AB - PURPOSE: To evaluate the association between subfoveal choroidal thickness (SFCT) and branch retinal vein occlusion (BRVO) eyes treated with antivascular endothelial growth factor (anti-VEGF) therapy. METHODS: Retrospective cohort study of treatment naive BRVO eyes treated with 3 monthly anti-VEGF injections. All patients received enhanced depth imaging spectral-domain optical coherence tomography scans to determine SFCT and central macular thickness (CMT). Baseline predictors (particularly SFCT) for functional response (best-corrected visual acuity (BCVA) gain >=2 lines) were assessed at 3 months using univariate and multivariate analyses. RESULTS: Forty eyes from 39 patients were included. Mean baseline SFCT was higher in functional responders (240.4+/-73.1 um), compared with both non-responders (193.3+/-63.6 um; p=0.036) and their corresponding fellow eye (202.2+/-67.1 um; p=0.022). A higher baseline SFCT (for every 100 um increase in SFCT) was found to be a positive predictor for functional response (regression coefficient: 1.1; p=0.03) on univariate analysis but not multivariate analysis. A worse baseline BCVA (for every 0.1 logMAR increase) was a positive predictor for visual improvement with an adjusted OR of 1.30 (95% CI 1.03 to 1.63; p=0.0009) on multivariate analysis. CONCLUSIONS: Patients with BRVO with a worse initial BCVA are most likely to achieve visual improvement following anti VEGF therapy. Additionally, baseline SFCT may also help predict which patients with BRVO have favourable visual outcomes. Patients with an initial choroidal thickness thicker than their fellow eye are more likely to have short-term visual improvement following treatment. PMID- 29567793 TI - Corneal transplant follow-up study II (CTFS II): a prospective clinical trial to determine the influence of HLA class II matching on corneal transplant rejection: baseline donor and recipient characteristics. AB - PURPOSE: To describe a study to determine the influence of HLA class II matching on allograft rejection of high-risk, full-thickness corneal transplants. METHODS: A prospective, longitudinal, clinical trial (ISRCTN25094892) with a primary outcome measure of time to first clinically determined rejection episode. Tissue typing used DNA-based techniques. Corneas were allocated to patients with <=2 human leucocyte antigen (HLA) class I antigen mismatches by cohort minimisation to achieve 0, 1 or 2 HLA class II (HLA-DR) antigen mismatches. Transplants were to be followed up at 6 months and then annually on the anniversary of surgery for 5 years. Power calculations estimated a sample size of 856 transplants to detect a 0.1 difference in probability of rejection at 1 year between HLA class II matched and mismatched transplants at the 5% level of significance with 80% power. RESULTS: To allow for loss to follow-up, 1133 transplants in 980 patients were accrued to the study between 3 September 1998 and 2 June 2011. 17% of transplants had 0 HLA-DR mismatches. The most frequent indication was bullous keratopathy, accounting for 27% of transplants and 54% of the transplants were regrafts. Median waiting time for a matched graft was 3 months. Donor and recipient characteristics were distributed evenly across the study groups. CONCLUSION: Recruitment to the CFS II has closed with 1077/1133 transplants meeting all the study criteria. Follow-up has been completed and final analysis of the data has started. TRIAL REGISTRATION NUMBER: ISRCTN25094892 andUKCRNID9871, Pre-results.

AB - AIMS: To investigate, with optical coherence tomography angiography (OCTA), short term changes of type 1 choroidal neovascularisation (CNV), secondary to exudative age-related macular degeneration, after anti-vascular endothelial growth factor (VEGF) treatment. METHODS: Patients affected by type 1 CNV treated with intravitreal anti-VEGF were consecutively enrolled. All patients underwent OCTA examination before and 48 hours after anti-VEGF treatment. Quantitative and qualitative vascular and morphological macular changes were evaluated. RESULTS: Sixteen eyes were included (11 treated with aflibercept and 5 with ranibizumab). Both CNV mean area and pigment epithelium detachment significantly reduced (p=0.0004 and p=0.0007, respectively) after treatment. Cystoid macular oedema (four eyes) decreased in all cases. Neuroretinal detachment (13 eyes) decreased in 85% of cases (11 eyes). Fine CNV vessels density decreased in 75% (12 eyes), whereas larger CNV vessels density remained stable in 66.7% (10 eyes), choroidal flow void signal (7 eyes at baseline) increased in 42.9% (3 eyes) of them and remained stable in 57.1% (4 eyes). Interoperator reproducibility for OCT examination was good for all measurements (intraclass correlation coefficient>0.65). CONCLUSION: Early remodelling of type 1 CNV network after treatment may be non-invasively and reproducibly analysed by means of OCTA. Choroidal perfusion impairment, choroidal flow void signal, surrounding CNV may change during treatment. PMID- 29567796 TI - How an intrinsic ligand tunes the activity of a potassium channel. PMID- 29567795 TI - Dynamic rearrangement of the intrinsic ligand regulates KCNH potassium channels. AB - KCNH voltage-gated potassium channels (EAG, ERG, and ELK) play significant roles in neuronal and cardiac excitability. They contain cyclic nucleotide-binding homology domains (CNBHDs) but are not directly regulated by cyclic nucleotides. Instead, the CNBHD ligand-binding cavity is occupied by an intrinsic ligand, which resides at the intersubunit interface between the N-terminal eag domain and the C-terminal CNBHD. We show that, in Danio rerio ELK channels, this intrinsic ligand is critical for voltage-dependent potentiation (VDP), a process in which channel opening is stabilized by prior depolarization. We demonstrate that an exogenous peptide corresponding to the intrinsic ligand can bind to and regulate zebrafish ELK channels. This exogenous intrinsic ligand inhibits the channels before VDP and potentiates the channels after VDP. Furthermore, using transition metal ion fluorescence resonance energy transfer and a fluorescent noncanonical amino acid L-Anap, we show that there is a rearrangement of the intrinsic ligand relative to the CNBHD during VDP. We propose that the intrinsic ligand switches from antagonist to agonist as a result of a rearrangement of the eag domain-CNBHD interaction during VDP. PMID- 29567797 TI - Human ALPI deficiency causes inflammatory bowel disease and highlights a key mechanism of gut homeostasis. AB - Herein, we report the first identification of biallelic-inherited mutations in ALPI as a Mendelian cause of inflammatory bowel disease in two unrelated patients. ALPI encodes for intestinal phosphatase alkaline, a brush border metalloenzyme that hydrolyses phosphate from the lipid A moiety of lipopolysaccharides and thereby drastically reduces Toll-like receptor 4 agonist activity. Prediction tools and structural modelling indicate that all mutations affect critical residues or inter-subunit interactions, and heterologous expression in HEK293T cells demonstrated that all ALPI mutations were loss of function. ALPI mutations impaired either stability or catalytic activity of ALPI and rendered it unable to detoxify lipopolysaccharide-dependent signalling. Furthermore, ALPI expression was reduced in patients' biopsies, and ALPI activity was undetectable in ALPI-deficient patient's stool. Our findings highlight the crucial role of ALPI in regulating host-microbiota interactions and restraining host inflammatory responses. These results indicate that ALPI mutations should be included in screening for monogenic causes of inflammatory bowel diseases and lay the groundwork for ALPI-based treatments in intestinal inflammatory disorders.

AB - Ponatinib has potent activity against native and mutant BCR-ABL1, including BCR ABL1T315I The pivotal phase 2 Ponatinib Ph+ ALL and CML Evaluation (PACE) trial evaluated efficacy and safety of ponatinib at a starting dose of 45 mg once daily in 449 patients with chronic myeloid leukemia (CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (ALL) resistant/intolerant to dasatinib or nilotinib, or with BCR-ABL1T315I This analysis focuses on chronic-phase CML (CP CML) patients (n = 270) with 56.8-month median follow-up. Among 267 evaluable patients, 60%, 40%, and 24% achieved major cytogenetic response (MCyR), major molecular response (MMR), and 4.5-log molecular response, respectively. The probability of maintaining MCyR for 5 years was 82% among responders. Dose reductions were implemented in October 2013 to decrease the risk of arterial occlusive events (AOEs); >=90% of CP-CML patients who had achieved MCyR or MMR maintained response 40 months after elective dose reductions. Estimated 5-year overall survival was 73%. In CP-CML patients, the most common treatment-emergent adverse events were rash (47%), abdominal pain (46%), thrombocytopenia (46%), headache (43%), dry skin (42%), and constipation (41%). The cumulative incidence of AOEs in CP-CML patients increased over time to 31%, while the exposure adjusted incidence of new AOEs (15.8 and 4.9 per 100 patient-years in years 1 and 5, respectively) did not increase over time. These final PACE results demonstrate ponatinib provides durable and clinically meaningful responses, irrespective of dose reductions, in this population of heavily pretreated CP-CML patients. This trial was registered at www.clinicaltrials.gov as #NCT01207440. PMID- 29567799 TI - Pan-SRC kinase inhibition blocks B-cell receptor oncogenic signaling in non Hodgkin lymphoma. AB - In diffuse large B-cell lymphoma (DLBCL), activation of the B-cell receptor (BCR) promotes multiple oncogenic signals, which are essential for tumor proliferation. Inhibition of the Bruton's tyrosine kinase (BTK), a BCR downstream target, is therapeutically effective only in a subgroup of patients with DLBCL. Here, we used lymphoma cells isolated from patients with DLBCL to measure the effects of targeted therapies on BCR signaling and to anticipate response. In lymphomas resistant to BTK inhibition, we show that blocking BTK activity enhanced tumor dependencies from alternative oncogenic signals downstream of the BCR, converging on MYC upregulation. To completely ablate the activity of the BCR, we genetically and pharmacologically repressed the activity of the SRC kinases LYN, FYN, and BLK, which are responsible for the propagation of the BCR signal. Inhibition of these kinases strongly reduced tumor growth in xenografts and cell lines derived from patients with DLBCL independent of their molecular subtype, advancing the possibility to be relevant therapeutic targets in broad and diverse groups of DLBCL patients.

PMID- 29567802 TI - Mycoplasma genitalium: high prevalence of resistance to macrolides and frequent anorectal infection in men who have sex with men in western Sydney. AB - OBJECTIVES: We aimed to estimate the prevalence of Mycoplasma genitalium infection and of mutations linked to macrolide resistance using the ResistancePlus MG assay (SpeeDx, Sydney, New South Wales, Australia) in first void urine (FVU), anorectal and oropharyngeal samples from men who have sex with men (MSM) attending Western Sydney Sexual Health Centre (WSSHC). METHODS: Consecutive symptomatic and asymptomatic MSM attending for STI testing were prospectively enrolled. M. genitalium testing using the ResistancePlus MG assay was performed on FVU, anorectal and oropharyngeal samples routinely collected for Chlamydia trachomatis and Neisseria gonorrhoeae assays. RESULTS: Overall, the prevalence of M. genitalium infection in the study group was 13.4% (68/508). Most (79.4%, 54/68) M. genitalium harboured macrolide resistance mutations (87.5% of urethral and 75.6% of anorectal infections). The anorectum was the most commonly infected site (45/505, 8.9%), followed by the urethra (24/508, 4.7%). No oropharyngeal M. genitalium infections were detected (0/508). Most of the anorectal (93.3%) and urethral (79.2%) infections were asymptomatic.MSM who were taking HIV pre-exposure prophylaxis (PrEP) were twice as likely to be infected with M. genitalium compared with MSM who were not on PrEP (OR 2.1, 95% CI 1.3 to 3.6; P=0.0041). Always using condoms for anal sex in the last 3 months was protective of infection (OR 0.8, 95% CI 0.6 to 1.0; P=0.0186). CONCLUSIONS: We demonstrated a high prevalence of M. genitalium and very high levels of macrolide resistance among MSM attending WSSHC. Our findings support the routine use of an assay to detect macrolide resistance mutations in M. genitalium infections. This will ensure, in regions or populations with high rates of macrolide resistance among M. genitalium strains, that first-line treatment with azithromycin will only be used if a macrolide-sensitive strain is identified. PMID- 29567803 TI - Canadian Child Safety Report Card: a comparison of injury prevention practices across provinces. AB - BACKGROUND: Injury prevention report cards that raise awareness about the preventability of childhood injuries have been published by the European Child Safety Alliance and the WHO. These report cards highlight the variance in injury prevention practices around the world. Policymakers and stakeholders have identified research evidence as an important enabler to the enactment of injury legislation. In Canada, there is currently no childhood injury report card that ranks provinces on injury rates or evidence-based prevention policies. METHODS: Three key measures, with five metrics, were used to compare provinces on childhood injury prevention rates and strategies, including morbidity, mortality and policy indicators over time (2006-2012). Nine provinces were ranked on five metrics: (1) population-based hospitalisation rate/100 000; (2) per cent change in hospitalisation rate/100 000; (3) population-based mortality rate/100 000; (4) per cent change in mortality rate/100 000; (5) evidence-based policy assessment. RESULTS: Of the nine provinces analysed, British Columbia ranked highest in Canada and Saskatchewan lowest. British Columbia had a morbidity and mortality rate that was close to the Canadian average and decreased over the study period. British Columbia also had a number of injury prevention policies and legislation in place that followed best practice guidelines. Saskatchewan had a higher rate of injury hospitalisation and death; however, Saskatchewan's rate decreased over time. Saskatchewan had a number of prevention policies in place but had not enacted bicycle helmet legislation. CONCLUSIONS: Future preventative efforts should focus on harmonising policies across all provinces in Canada that reflect evidence-based best practices. PMID- 29567804 TI - Primary Traumatic Axonopathy in Mice Subjected to Impact Acceleration: A Reappraisal of Pathology and Mechanisms with High-Resolution Anatomical Methods. AB - Traumatic axonal injury (TAI) is a common neuropathology in traumatic brain injury and is featured by primary injury to axons. Here, we generated TAI with impact acceleration of the head in male Thy1-eYFP-H transgenic mice in which specific populations of neurons and their axons are labeled with yellow fluorescent protein. This model results in axonal lesions in multiple axonal tracts along with blood-brain barrier disruption and neuroinflammation. The corticospinal tract, a prototypical long tract, is severely affected and is the focus of this study. Using optimized CLARITY at single-axon resolution, we visualized the entire corticospinal tract volume from the pons to the cervical spinal cord in 3D and counted the total number of axonal lesions and their progression over time. Our results divulged the presence of progressive traumatic axonopathy that was maximal at the pyramidal decussation. The perikarya of injured corticospinal neurons atrophied, but there was no evidence of neuronal cell death. We also used CLARITY at single-axon resolution to explore the role of the NMNAT2-SARM1 axonal self-destruction pathway in traumatic axonopathy. When we interfered with this pathway by genetically ablating SARM1 or by pharmacological strategies designed to increase levels of Nicotinamide (Nam), a feedback inhibitor of SARM1, we found a significant reduction in the number of axonal lesions early after injury. Our findings show that high-resolution neuroanatomical strategies reveal important features of TAI with biological implications, especially the progressive axonopathic nature of TAI and the role of the NMNAT2-SARM1 pathway in the early stages of axonopathy.SIGNIFICANCE STATEMENT In the first systematic application of novel high-resolution neuroanatomical tools in neuropathology, we combined CLARITY with 2-photon microscopy, optimized for detection of single axonal lesions, to reconstruct the injured mouse brainstem in a model of traumatic axonal injury (TAI) that is a common pathology associated with traumatic brain injury. The 3D reconstruction of the corticospinal tract at single-axon resolution allowed for a more advanced level of qualitative and quantitative understanding of TAI. Using this model, we showed that TAI is an axonopathy with a prominent role of the NMNAT2-SARM1 molecular pathway, that is also implicated in peripheral neuropathy. Our results indicate that high-resolution anatomical models of TAI afford a level of detail and sensitivity that is ideal for testing novel molecular and biomechanical hypotheses.

AB - Signal recognition particle (SRP) targets proteins to the endoplasmic reticulum (ER). SRP recognizes the ribosome synthesizing a signal sequence and delivers it to the SRP receptor (SR) on the ER membrane followed by the transfer of the signal sequence to the translocon. Here, we present the cryo-electron microscopy structure of the mammalian translating ribosome in complex with SRP and SR in a conformation preceding signal sequence handover. The structure visualizes all eukaryotic-specific SRP and SR proteins and reveals their roles in stabilizing this conformation by forming a large protein assembly at the distal site of SRP RNA. We provide biochemical evidence that the guanosine triphosphate hydrolysis of SRP.SR is delayed at this stage, possibly to provide a time window for signal sequence handover to the translocon. PMID- 29567808 TI - Legacy nitrogen may prevent achievement of water quality goals in the Gulf of Mexico. AB - In August 2017, the Gulf of Mexico's hypoxic zone was declared to be the largest ever measured. It has been estimated that a 60% decrease in watershed nitrogen (N) loading may be necessary to adequately reduce eutrophication in the Gulf. However, to date there has been no rigorous assessment of the effect of N legacies on achieving water quality goals. In this study, we show that even if agricultural N use became 100% efficient, it would take decades to meet target N loads due to legacy N within the Mississippi River basin. Our results suggest that both long-term commitment and large-scale changes in agricultural management practices will be necessary to decrease Mississippi N loads and to meet current goals for reducing the size of the Gulf hypoxic zone. PMID- 29567809 TI - The threshold for conscious report: Signal loss and response bias in visual and frontal cortex. AB - Why are some visual stimuli consciously detected, whereas others remain subliminal? We investigated the fate of weak visual stimuli in the visual and frontal cortex of awake monkeys trained to report stimulus presence. Reported stimuli were associated with strong sustained activity in the frontal cortex, and frontal activity was weaker and quickly decayed for unreported stimuli. Information about weak stimuli could be lost at successive stages en route from the visual to the frontal cortex, and these propagation failures were confirmed through microstimulation of area V1. Fluctuations in response bias and sensitivity during perception of identical stimuli were traced back to prestimulus brain-state markers. A model in which stimuli become consciously reportable when they elicit a nonlinear ignition process in higher cortical areas explained our results. PMID- 29567810 TI - Two-billion-year-old evaporites capture Earth's great oxidation. AB - Major changes in atmospheric and ocean chemistry occurred in the Paleoproterozoic era (2.5 to 1.6 billion years ago). Increasing oxidation dramatically changed Earth's surface, but few quantitative constraints exist on this important transition. This study describes the sedimentology, mineralogy, and geochemistry of a 2-billion-year-old, ~800-meter-thick evaporite succession from the Onega Basin in Russian Karelia. The deposit consists of a basal unit dominated by halite (~100 meters) followed by units dominated by anhydrite-magnesite (~500 meters) and dolomite-magnesite (~200 meters). The evaporite minerals robustly constrain marine sulfate concentrations to at least 10 millimoles per kilogram of water, representing an oxidant reservoir equivalent to more than 20% of the modern ocean-atmosphere oxidizing capacity. These results show that substantial amounts of surface oxidant accumulated during this critical transition in Earth's oxygenation. PMID- 29567811 TI - Epigenome-wide SRC-1-Mediated Gene Silencing Represses Cellular Differentiation in Advanced Breast Cancer. AB - Purpose: Despite the clinical utility of endocrine therapies for estrogen receptor-positive (ER) breast cancer, up to 40% of patients eventually develop resistance, leading to disease progression. The molecular determinants that drive this adaptation to treatment remain poorly understood. Methylome aberrations drive cancer growth yet the functional role and mechanism of these epimutations in drug resistance are poorly elucidated.Experimental Design: Genome-wide multi omics sequencing approach identified a differentially methylated hub of prodifferentiation genes in endocrine resistant breast cancer patients and cell models. Clinical relevance of the functionally validated methyl-targets was assessed in a cohort of endocrine-treated human breast cancers and patient derived ex vivo metastatic tumors.Results: Enhanced global hypermethylation was observed in endocrine treatment resistant cells and patient metastasis relative to sensitive parent cells and matched primary breast tumor, respectively. Using paired methylation and transcriptional profiles, we found that SRC-1-dependent alterations in endocrine resistance lead to aberrant hypermethylation that resulted in reduced expression of a set of differentiation genes. Analysis of ER positive endocrine-treated human breast tumors (n = 669) demonstrated that low expression of this prodifferentiation gene set significantly associated with poor clinical outcome (P = 0.00009). We demonstrate that the reactivation of these genes in vitro and ex vivo reverses the aggressive phenotype.Conclusions: Our work demonstrates that SRC-1-dependent epigenetic remodeling is a 'high level' regulator of the poorly differentiated state in ER-positive breast cancer. Collectively these data revealed an epigenetic reprograming pathway, whereby concerted differential DNA methylation is potentiated by SRC-1 in the endocrine resistant setting.

AB - Purpose: Plasma cell-free DNA (cfDNA) genotyping is increasingly used in cancer care, but assay accuracy has been debated. Because most cfDNA is derived from peripheral blood cells (PBC), we hypothesized that nonmalignant mutations harbored by hematopoietic cells (clonal hematopoiesis, CH) could be a cause of false-positive plasma genotyping.Experimental Design: We identified patients with advanced non-small cell lung cancer (NSCLC) with KRAS, JAK2, or TP53 mutations identified in cfDNA. With consent, PBC DNA was tested using droplet digital PCR (ddPCR) or next-generation sequencing (NGS) to test for CH-derived mutations.Results: We first studied plasma ddPCR results from 58 patients with EGFR-mutant NSCLC. Two had KRAS G12X detected in cfDNA, and both were present in PBC, including one where the KRAS mutation was detected serially for 20 months. We then studied 143 plasma NGS results from 122 patients with NSCLC and identified 5 JAK2 V617F mutations derived from PBC. In addition, 108 TP53 mutations were detected in cfDNA; for 33 of the TP53 mutations, PBC and tumor NGS were available for comparison, and 5 were present in PBC but absent in tumor, consistent with CH.Conclusions: We find that most JAK2 mutations, some TP53 mutations, and rare KRAS mutations detected in cfDNA are derived from CH not tumor. Clinicians ordering plasma genotyping must be prepared for the possibility that mutations detected in plasma, particularly in genes mutated in CH, may not represent true tumor genotype. Efforts to use plasma genotyping for cancer detection may need paired PBC genotyping so that CH-derived mutations are not misdiagnosed as occult malignancy. Clin Cancer Res; 24(18); 4437-43.

AB - BACKGROUND: Hopes of parents of children with serious illness play an important role in decision-making and coping. Little is known about how parent hopes change over time. We describe the changes in parent hopes across multiple domains and time intervals, examine hopes in a subgroup of parents whose child died, and explore the maintenance of domains over time. METHODS: In a mixed-methods prospective cohort study on decision-making, parents of seriously ill children reported demographic characteristics and hopes at baseline and reported any changes in hopes at 4-, 8-, 12-, 16-, and 20-month follow-up visits. Hopes were coded into 9 domains. Hope changes and domain changes were identified for each parent at each visit. RESULTS: One hundred and ninety-nine parents of 158 patients most often reported hopes in the domains of quality of life (75%), physical body (69%), future well-being (47%), and medical care (34%). Hope percentages increased over time for quality of life (84%), future well-being (64%), and broader meaning (21%). The hope domains reported by parents of children who died were similar to the rest of the sample. The majority of parents who completed 5 to 6 follow-up visits changed at least 1 domain. At the individual parent level, some domains revealed considerable change over time, whereas other domains were stable among a subset of parents. CONCLUSIONS: The specific hopes and overall areas of hope of parents of seriously ill children vary over time, although most hopes fall within 4 major areas. Accordingly, clinicians should regularly check with parents about their current hopes. PMID- 29567814 TI - Motor Impairment Trends in Extremely Preterm Children: 1991-2005. AB - BACKGROUND: There are increasing numbers of surviving children who were born extremely preterm (EP; gestational age <28 weeks) or extremely low birth weight (ELBW; birth weight <1000 g). Our objective in this study was to compare the rates of motor impairment at 8 years of age between 3 cohorts of EP and/or ELBW and term-born children to establish if motor impairment rates are changing over time. METHODS: All children born EP and/or ELBW in the calendar years of 1991 1992, 1997, and 2005 in Victoria, Australia, were recruited at birth. Randomly selected normal birth weight (>2499 g) and term-born controls were matched for expected date of birth, sex, and sociodemographic status. At 8 years' corrected age, motor impairment was defined as cerebral palsy (CP) or a score less than the fifth centile on the Movement Assessment Battery for Children for the 1991-1992 and 1997 cohorts and less than or equal to the fifth centile on the Movement Assessment Battery for Children-Second Edition for the 2005 cohort. RESULTS: Motor impairment was more likely in children born EP and/or ELBW compared with children born at term for all epochs. There was a significant increase in motor impairment in EP and/or ELBW children over the 3 eras, from 23% in 1991-1992 and 26% in 1997 to 37% in 2005 (chi2trend = 10.2; P = .001). This was due to an increase in non-CP motor impairment (13% in 1991 to 1992; 15% in 1997; 26% in 2005; chi2trend = 12.5; P < .001), not CP (11% in 1991 to 1992; 11% in 1997; 12% in 2005). CONCLUSIONS: The rate of motor impairment in EP and/or ELBW children assessed at 8 years of age increased between eras, an increase caused by non-CP motor impairment.

AB - BACKGROUND: The prognostic factors and the efficacy of first-line chemotherapy remain unclear in patients with advanced thymic carcinoma. MATERIALS AND METHODS: We conducted a multi-institutional retrospective study named NEJ023 for patients with advanced thymic carcinoma. All patients without any indication of curative treatment were treated with chemotherapy from 1995 to 2014 at 40 institutions of the North East Japan Study Group. RESULTS: A total of 286 patients with advanced thymic carcinoma were analyzed. First-line chemotherapy included platinum-based doublets in 62.2% of the patients, monotherapy in 3.5%, and other multidrug chemotherapy (e.g., cisplatin, doxorubicin, vincristine, and cyclophosphamide [ADOC]) in 34.3%. The median follow-up period was 55.5 months, and the median overall survival (OS) from the start of first-line chemotherapy was 30.7 months (95% confidence interval, 25.9-35.9 months). There was no significant difference in OS among different first-line chemotherapy regimens (e.g., between carboplatin/paclitaxel and ADOC, median OS: 27.8 vs. 29.9 months). Masaoka-Koga stage IVa and volume reduction surgery were favorable prognostic factors for OS in the multivariate analysis using the Cox proportional hazards model. CONCLUSION: The efficacy of each first-line chemotherapy regimen for advanced thymic carcinoma did not vary significantly. Our results might support the adequacy of the use of carboplatin/paclitaxel as first-line chemotherapy for these patients. IMPLICATIONS FOR PRACTICE: Because of its rarity, there is limited information about prognostic factors and efficacy of chemotherapy in patients with advanced thymic carcinoma. This is the largest data set for those patients treated with chemotherapy. This study suggests there is no significant difference in efficacy between carboplatin/paclitaxel and cisplatin/doxorubicin/vincristine/cyclophosphamide for advanced thymic carcinoma. This result can support the adequacy of the selection of platinum doublets as treatment for those patients, rather than anthracycline-based multidrug regimen. PMID- 29567821 TI - Costs of Cancer Care Across the Disease Continuum. AB - PURPOSE: The aim of this study was to estimate Medicare payments for cancer care during the initial, continuing, and end-of-life phases of care for 10 malignancies and to examine variation in expenditures according to patient characteristics and cancer severity. MATERIALS AND METHODS: We used linked Surveillance, Epidemiology and End Results-Medicare data to identify patients aged 66-99 years who were diagnosed with one of the following 10 cancers: prostate, bladder, esophageal, pancreatic, lung, liver, kidney, colorectal, breast, or ovarian, from 2007 through 2012. We attributed payments for each patient to a phase of care (i.e., initial, continuing, or end of life), based on time from diagnosis until death or end of study interval. We summed payments for all claims attributable to the primary cancer diagnosis and analyzed the overall and phase-based costs and then by differing demographics, cancer stage, geographic region, and year of diagnosis. RESULTS: We identified 428,300 patients diagnosed with one of the 10 malignancies. Annual payments were generally highest during the initial phase. Mean expenditures across cancers were $14,381 during the initial phase, $2,471 for continuing, and $13,458 at end of life. Payments decreased with increasing age. Black patients had higher payments for four of five cancers with statistically significant differences. Stage III cancers posed the greatest annual cost burden for four cancer types. Overall payments were stable across geographic region and year. CONCLUSION: Considerable differences exist in expenditures across phases of cancer care. By understanding the drivers of such payment variations across patient and tumor characteristics, we can inform efforts to decrease payments and increase quality, thereby reducing the burden of cancer care. IMPLICATIONS FOR PRACTICE: Considerable differences exist in expenditures across phases of cancer care. There are further differences by varying patient characteristics. Understanding the drivers of such payment variations across patient and tumor characteristics can inform efforts to decrease costs and increase quality, thereby reducing the burden of cancer care. PMID- 29567822 TI - Families' Sense of Abandonment When Patients Are Referred to Hospice. AB - BACKGROUND: Terminally ill patients with cancer and their families may have a sense of abandonment when they are referred to hospice. This study aimed to clarify the prevalence of families' sense of abandonment, explore the association between the sense of abandonment and the oncologists' behaviors, and investigate the association between the sense of abandonment and the families' depression and complicated grief. PATIENTS AND METHODS: This was part of a nationwide self reported questionnaire survey of bereaved families of patients with cancer who died in inpatient hospices. We sent questionnaires to 947 bereaved families of patients with cancer who died in 133 certified hospices between May 2012 and January 2014. RESULTS: Among 707 responses obtained, a total of 189 (26.7%) families felt abandoned. The factors significantly associated with a greater sense of abandonment were that the oncologists said there was nothing more to do for the patient, the patient's age of less than 60 years, and being the patient's spouse. The factors significantly associated with a lower sense of abandonment were that the oncologists reassured the patients that they had received the best anticancer treatment, that the oncologists recommended hospices as one potential choice rather than mandatory, and that a palliative care team provided care. Families with a sense of abandonment had higher scores on the Patient Health Questionnaire-9 (p = .096) and Brief Grief Questionnaire (p < .001). CONCLUSION: Approximately a quarter of bereaved families had a sense of abandonment, which was associated with a higher rate of complicated grief. Oncologists may reduce the sense of abandonment by reassuring that the patients received the best anticancer treatment, recommending hospices as a potential choice rather than as mandatory, and by not saying there is nothing that can be done for the patients. IMPLICATIONS FOR PRACTICE: This self-reported questionnaire study investigated the prevalence of families' feelings of abandonment when they were referred to hospice care, focusing on the association of sense of abandonment and the behavior of their physicians. Nearly a quarter of families felt abandoned by the referral to hospice, and the behavior of some oncologists was associated with the sense of abandonment. PMID- 29567823 TI - Cervical Cancer in Ethiopia: The Effect of Adherence to Radiotherapy on Survival. AB - BACKGROUND: Discontinuation of radiotherapy (RT) for cervical cancer (CC) in sub Saharan Africa is common because of patient- and health service-related reasons. This analysis describes toxicities and the effect of adherence on survival. MATERIALS AND METHODS: A total of 788 patients with CC (2008-2012) who received RT at Addis Ababa University Hospital were included. External beam RT without brachytherapy was performed according to local guidelines. We previously described survival and prognostic factors. Now we analyzed adherence and survival according to total doses received. Adjustment via multivariate cox regression analysis was done. RESULTS: One-year overall survival (OS) after radical RT (n = 180) for International Federation of Gynecology and Obstetrics (FIGO) stages IIA IIIA was 89% for discontinuation (<72 Gy) and 96% for adherence (>=72 Gy; hazard ratio [HR], 1.3; 95% confidence interval [CI], 0.5-3.3). One-year OS after nonradical RT (n = 389) for FIGO stages IIIB-IVA was 71% for discontinuation (<40 Gy) and 87% for adherence (44-50 Gy; HR, 3.1; 95% CI, 1.4-6.9). One-year OS for FIGO stages IIIB-IVB (n = 219) after one compared with two or more palliative single fractions of 10 Gy were 14% and 73% respectively (HR, 7.3; 95% CI, 3.3 16). Reasons for discontinuation were toxicities, economic background, and RT machine breakdown. Grade 1-2 late toxicities were common (e.g., 30% proctitis, 22% incontinence). Grade 3 early and late toxicities were seen in 5% and 10% respectively; no grade 4 toxicities occurred. CONCLUSION: Patients who adhered to guideline-conforming RT had optimum survival. Better supportive care, brachytherapy to reduce toxicities, socioeconomic support, and additional radiation capacities could contribute to better adherence and survival. IMPLICATIONS FOR PRACTICE: This study presents the effect of adherence on survival of 788 patients with cervical cancer receiving external beam radiotherapy without brachytherapy in Ethiopia. Discontinuation of planned radiotherapy according to local guidelines considerably reduced survival for all International Federation of Gynecology and Obstetrics (FIGO) stages treated (hazard ratios were 1.3, 3.1, and 7.3 for FIGO stages IIA-IIIA and IIIB-IVA and the palliative approach, respectively). Early toxicity (5% grade 3) should be treated to improve adherence. Economic difficulties and machine breakdown should also be addressed to reduce discontinuation and improve survival. PMID- 29567824 TI - Serial Troponin for Early Detection of Nivolumab Cardiotoxicity in Advanced Non Small Cell Lung Cancer Patients. AB - BACKGROUND: Rare cases of severe myocarditis are reported during treatment with nivolumab. Troponin, a biomarker of cardiac damage, is a key component of the diagnostic workup of many cardiac disorders, including myocarditis. This study investigates the role of troponin to assess cardiac involvement during nivolumab therapy for non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: We evaluated 59 NSCLC patients, analyzing serum samples collected within a translational research study. Troponin above the upper normal limit (0.046 ng/mL) was defined as Tn+, whereas normal but detectable troponin (0.015-0.045) was defined as Tndet. Troponin alterations were interpreted on the grounds of the following elements: peak values and time curve, cardiac comorbidities, signs and symptoms coincident to troponin elevation, ECG, echocardiography, and disease progression. RESULTS: No patient had cardiovascular events. Among 362 available blood samples, Tn+ (max 0.317 ng/mL) was found in 13 determinations belonging to 6 patients. Seven other patients had isolated Tndet. In five patients, Tn+ was attributed to cardiac comorbidities, disease progression, or worsening clinical status. One patient without cardiac history and in good clinical condition had a sustained troponin increase-soon after the start of therapy-and after careful evaluation of all relevant elements, it was interpreted as a marker of nivolumab related subclinical myocarditis. CONCLUSION: Tn+ may occur in NSCLC patients treated with nivolumab, but in most cases it does not indicate nivolumab cardiotoxicity. In some cases, however, a careful interpretation of troponin alteration, especially at the beginning of therapy, enables identification of subclinical myocarditis, thus allowing early cardiac treatment. IMPLICATIONS FOR PRACTICE: Myocarditis is a rare but serious adverse event of immune checkpoint blockade with nivolumab, which needs to be recognized as soon as possible. This article suggests that troponin, a user-friendly biomarker of myocardial cytotoxicity, might be useful for early detection of immune-mediated myocarditis. However, because troponin abnormalities might also be related to a number of conditions capable of causing myocardial oxygen demand-supply mismatch, a careful cardiac assessment should be performed in non-small cell lung cancer patients in order to properly interpret any troponin increase. According to the available evidence, monitoring troponin during the first weeks of treatment can be considered reasonable.

PMID- 29567826 TI - Treatment and Survival of Patients with Colon Cancer Aged 80 Years and Older: A EURECCA International Comparison. AB - BACKGROUND: Colon cancer in older patients represents a major public health issue. As older patients are hardly included in clinical trials, the optimal treatment of these patients remains unclear. The present international EURECCA comparison explores possible associations between treatment and survival outcomes in elderly colon cancer patients. SUBJECTS, MATERIALS, AND METHODS: National data from Belgium, Denmark, The Netherlands, Norway, and Sweden were obtained, as well as a multicenter surgery cohort from Germany. Patients aged 80 years and older, diagnosed with colon cancer between 2001 and 2010, were included. The study interval was divided into two periods: 2001-2006 and 2007-2010. The proportion of surgical treatment and chemotherapy within a country and its relation to relative survival were calculated for each time frame. RESULTS: Overall, 50,761 patients were included. At least 94% of patients with stage II and III colon cancer underwent surgical removal of the tumor. For stage II-IV, the proportion of chemotherapy after surgery was highest in Belgium and lowest in The Netherlands and Norway. For stage III, it varied from 24.8% in Belgium and 3.9% in Norway. For stage III, a better adjusted relative survival between 2007 and 2010 was observed in Sweden (adjusted relative excess risk [RER] 0.64, 95% confidence interval [CI]: 0.54-0.76) and Norway (adjusted RER 0.81, 95% CI: 0.69-0.96) compared with Belgium. CONCLUSION: There is substantial variation in the rate of treatment and survival between countries for patients with colon cancer aged 80 years or older. Despite higher prescription of adjuvant chemotherapy, poorer survival outcomes were observed in Belgium. No clear linear pattern between the proportion of chemotherapy and better adjusted relative survival was observed. IMPLICATIONS FOR PRACTICE: With the increasing growth of the older population, clinicians will be treating an increasing number of older patients diagnosed with colon cancer. No clear linear pattern between adjuvant chemotherapy and better adjusted relative survival was observed. Future studies should also include data on surgical quality.

PMID- 29567831 TI - The influence of bat echolocation call duration and timing on auditory encoding of predator distance in noctuoid moths. AB - Animals co-occur with multiple predators, making sensory systems that can encode information about diverse predators advantageous. Moths in the families Noctuidae and Erebidae have ears with two auditory receptor cells (A1 and A2) used to detect the echolocation calls of predatory bats. Bat communities contain species that vary in echolocation call duration, and the dynamic range of A1 is limited by the duration of sound, suggesting that A1 provides less information about bats with shorter echolocation calls. To test this hypothesis, we obtained intensity response functions for both receptor cells across many moth species for sound pulse durations representing the range of echolocation call durations produced by bat species in northeastern North America. We found that the threshold and dynamic range of both cells varied with sound pulse duration. The number of A1 action potentials per sound pulse increases linearly with increasing amplitude for long-duration pulses, saturating near the A2 threshold. For short sound pulses, however, A1 saturates with only a few action potentials per pulse at amplitudes far lower than the A2 threshold for both single sound pulses and pulse sequences typical of searching or approaching bats. Neural adaptation was only evident in response to approaching bat sequences at high amplitudes, not search phase sequences. These results show that, for short echolocation calls, a large range of sound levels cannot be coded by moth auditory receptor activity, resulting in no information about the distance of a bat, although differences in activity between ears might provide information about direction. PMID- 29567829 TI - The Pancreatic Cancer Microbiome Promotes Oncogenesis by Induction of Innate and Adaptive Immune Suppression. AB - We found that the cancerous pancreas harbors a markedly more abundant microbiome compared with normal pancreas in both mice and humans, and select bacteria are differentially increased in the tumorous pancreas compared with gut. Ablation of the microbiome protects against preinvasive and invasive pancreatic ductal adenocarcinoma (PDA), whereas transfer of bacteria from PDA-bearing hosts, but not controls, reverses tumor protection. Bacterial ablation was associated with immunogenic reprogramming of the PDA tumor microenvironment, including a reduction in myeloid-derived suppressor cells and an increase in M1 macrophage differentiation, promoting TH1 differentiation of CD4+ T cells and CD8+ T-cell activation. Bacterial ablation also enabled efficacy for checkpoint-targeted immunotherapy by upregulating PD-1 expression. Mechanistically, the PDA microbiome generated a tolerogenic immune program by differentially activating select Toll-like receptors in monocytic cells. These data suggest that endogenous microbiota promote the crippling immune-suppression characteristic of PDA and that the microbiome has potential as a therapeutic target in the modulation of disease progression.Significance: We found that a distinct and abundant microbiome drives suppressive monocytic cellular differentiation in pancreatic cancer via selective Toll-like receptor ligation leading to T-cell anergy. Targeting the microbiome protects against oncogenesis, reverses intratumoral immune tolerance, and enables efficacy for checkpoint-based immunotherapy. These data have implications for understanding immune suppression in pancreatic cancer and its reversal in the clinic. Cancer Discov; 8(4); 403-16.

PMID- 29567830 TI - Cardiac circRNAs arise mainly from constitutive exons rather than alternatively spliced exons. AB - Circular RNAs (circRNAs) are a relatively new class of RNA molecules, and knowledge about their biogenesis and function is still in its infancy. It was recently shown that alternative splicing underlies the formation of circular RNAs (circRNA) arising from the Titin (TTN) gene. Since the main mechanism by which circRNAs are formed is still unclear, we hypothesized that alternative splicing, and in particular exon skipping, is a major driver of circRNA production. We performed RNA sequencing on human and mouse hearts, mapped alternative splicing events, and overlaid these with expressed circRNAs at exon-level resolution. In addition, we performed RNA sequencing on hearts of Rbm20 KO mice to address how important Rbm20-mediated alternative splicing is in the production of cardiac circRNAs. In human and mouse hearts, we show that cardiac circRNAs are mostly (~90%) produced from constitutive exons and less (~10%) from alternatively spliced exons. In Rbm20 KO hearts, we identified 38 differentially expressed circRNAs of which 12 were produced from the Ttn gene. Even though Ttn appeared the most prominent target of Rbm20 for circularization, we also detected Rbm20 dependent circRNAs arising from other genes including Fan1, Stk39, Xdh, Bcl2l13, and Sorbs1 Interestingly, only Ttn circRNAs seemed to arise from Rbm20-mediated skipped exons. In conclusion, cardiac circRNAs are mostly derived from constitutive exons, suggesting that these circRNAs are generated at the expense of their linear counterpart and that circRNA production impacts the accumulation of the linear mRNA. PMID- 29567832 TI - Retinol dehydrogenase 11 is essential for the maintenance of retinol homeostasis in liver and testis in mice. AB - Retinol dehydrogenase 11 (RDH11) is a microsomal short-chain dehydrogenase/reductase that recognizes all-trans- and cis-retinoids as substrates and prefers NADPH as a cofactor. Previous work has suggested that RDH11 contributes to the oxidation of 11-cis-retinol to 11-cis-retinaldehyde during the visual cycle in the eye's retinal pigment epithelium. However, the role of RDH11 in metabolism of all-trans-retinoids remains obscure. Here, we report that microsomes isolated from the testes and livers of Rdh11-/- mice fed a regular diet exhibited a 3- and 1.7-fold lower rate of all-trans-retinaldehyde conversion to all-trans-retinol, respectively, than the microsomes of WT littermates. Testes and livers of Rdh11-/- mice fed a vitamin A-deficient diet had ~35% lower levels of all-trans-retinol than those of WT mice. Furthermore, the conversion of beta-carotene to retinol via retinaldehyde as an intermediate appeared to be impaired in the testes of Rdh11-/-/retinol-binding protein 4-/ (Rbp4-/-) mice, which lack circulating holo RBP4 and rely on dietary supplementation with beta-carotene for maintenance of their retinoid stores. Together, these results indicate that in mouse testis and liver, RDH11 functions as an all-trans-retinaldehyde reductase essential for the maintenance of physiological levels of all-trans-retinol under reduced vitamin A availability. PMID- 29567833 TI - Structural basis for the ability of MBD domains to bind methyl-CG and TG sites in DNA. AB - Cytosine methylation is a well-characterized epigenetic mark and occurs at both CG and non-CG sites in DNA. Both methylated CG (mCG)- and mCH (H = A, C, or T) containing DNAs, especially mCAC-containing DNAs, are recognized by methyl-CpG binding protein 2 (MeCP2) to regulate gene expression in neuron development. However, the molecular mechanism involved in the binding of methyl-CpG-binding domain (MBD) of MeCP2 to these different DNA motifs is unclear. Here, we systematically characterized the DNA-binding selectivities of the MBD domains in MeCP2 and MBD1-4 with isothermal titration calorimetry-based binding assays, mutagenesis studies, and X-ray crystallography. We found that the MBD domains of MeCP2 and MBD1-4 bind mCG-containing DNAs independently of the sequence identity outside the mCG dinucleotide. Moreover, some MBD domains bound to both methylated and unmethylated CA dinucleotide-containing DNAs, with a preference for the CAC sequence motif. We also found that the MBD domains bind to mCA or nonmethylated CA DNA by recognizing the complementary TG dinucleotide, which is consistent with an overlooked ligand of MeCP2, i.e. the matrix/scaffold attachment regions (MARs/SARs) with a consensus sequence of 5'-GGTGT-3' that was identified in early 1990s. Our results also explain why MeCP2 exhibits similar binding affinity to both mCA- and hmCA-containing dsDNAs. In summary, our results suggest that in addition to mCG sites, unmethylated CA or TG sites also serve as DNA-binding sites for MeCP2 and other MBD-containing proteins. This discovery expands the genome-wide activity of MBD-containing proteins in gene regulation. PMID- 29567834 TI - The cohesin module is a major determinant of cellulosome mechanical stability. AB - Cellulosomes are bacterial protein complexes that bind and efficiently degrade lignocellulosic substrates. These are formed by multimodular scaffolding proteins known as scaffoldins, which comprise cohesin modules capable of binding dockerin bearing enzymes and usually a carbohydrate-binding module that anchors the system to a substrate. It has been suggested that cellulosomes bound to the bacterial cell surface might be exposed to significant mechanical forces. Accordingly, the mechanical properties of these anchored cellulosomes may be important to understand and improve cellulosome function. Here we used single-molecule force spectroscopy to study the mechanical properties of selected cohesin modules from scaffoldins of different cellulosomes. We found that cohesins located in the region connecting the cell and the substrate are more robust than those located outside these two anchoring points. This observation applies to cohesins from primary scaffoldins (i.e. those that directly bind dockerin-bearing enzymes) from different cellulosomes despite their sequence differences. Furthermore, we also found that cohesin nanomechanics (specifically, mechanostability and the position of the mechanical clamp of cohesin) are not significantly affected by other cellulosomal components, including linkers between cohesins, multiple cohesin repeats, and dockerin binding. Finally, we also found that cohesins (from both the connecting and external regions) have poor refolding efficiency but similar refolding rates, suggesting that the high mechanostability of connecting cohesins may be an evolutionarily conserved trait selected to minimize the occurrence of cohesin unfolding, which could irreversibly damage the cellulosome. We conclude that cohesin mechanostability is a major determinant of the overall mechanical stability of the cellulosome. PMID- 29567835 TI - Molecular control of gene expression by Brucella BaaR, an IclR-type transcriptional repressor. AB - The general stress response sigma factor sigmaE1 directly and indirectly regulates the transcription of dozens of genes that influence stress survival and host infection in the zoonotic pathogen Brucella abortus Characterizing the functions of sigmaE1-regulated genes therefore would contribute to our understanding of B. abortus physiology and infection biology. sigmaE1 indirectly activates transcription of the IclR family regulator Bab2_0215, but the function of this regulator remains undefined. Here, we present a structural and functional characterization of Bab2_0215, which we have named B rucella adipic acid activated regulator (BaaR). We found that BaaR adopts a classic IclR-family fold and directly represses the transcription of two operons with predicted roles in carboxylic acid oxidation. BaaR binds two sites on chromosome II between baaR and a divergently transcribed hydratase/dehydrogenase (acaD2), and it represses transcription of both genes. We identified three carboxylic acids (adipic acid, tetradecanedioic acid, and epsilon-aminocaproic acid) and a lactone (epsilon caprolactone) that enhance transcription from the baaR and acaD2 promoters. However, neither the activating acids nor caprolactone enhanced transcription by binding directly to BaaR. Induction of baaR transcription by adipic acid required the gene bab2_0213, which encodes a major facilitator superfamily transporter, suggesting that Bab2_0213 transports adipic acid across the inner membrane. We conclude that a suite of structurally related organic molecules activate transcription of genes repressed by BaaR. Our study provides molecular-level understanding of a gene expression program in B. abortus that is downstream of sigmaE1. PMID- 29567836 TI - Histone deacetylase-mediated regulation of endolysosomal pH. AB - The pH of the endolysosomal system is tightly regulated by a balance of proton pump and leak mechanisms that are critical for storage, recycling, turnover, and signaling functions in the cell. Dysregulation of endolysosomal pH has been linked to aging, amyloidogenesis, synaptic dysfunction, and various neurodegenerative disorders, including Alzheimer's disease. Therefore, understanding the mechanisms that regulate luminal pH may be key to identifying new targets for managing these disorders. Meta-analysis of yeast microarray databases revealed that nutrient-limiting conditions inhibited the histone deacetylase (HDAC) Rpd3 and thereby up-regulated transcription of the endosomal Na+/H+ exchanger Nhx1, resulting in vacuolar alkalinization. Consistent with these findings, Rpd3 inhibition by the HDAC inhibitor and antifungal drug trichostatin A induced Nhx1 expression and vacuolar alkalinization. Bioinformatics analysis of Drosophila and mouse databases revealed that caloric control of the Nhx1 orthologs DmNHE3 and NHE6, respectively, is also mediated by HDACs. We show that NHE6 is a target of the transcription factor cAMP-response element-binding protein (CREB), a known regulator of cellular responses to low nutrient conditions, providing a molecular mechanism for nutrient- and HDAC dependent regulation of endosomal pH. Of note, pharmacological targeting of the CREB pathway to increase NHE6 expression helped regulate endosomal pH and correct defective clearance of amyloid Abeta in an apoE4 astrocyte model of Alzheimer's disease. These observations from yeast, fly, mouse, and cell culture models point to an evolutionarily conserved mechanism for HDAC-mediated regulation of endosomal NHE expression. Our insights offer new therapeutic strategies for modulation of endolysosomal pH in fungal infection and human disease. PMID- 29567837 TI - The BRD3 ET domain recognizes a short peptide motif through a mechanism that is conserved across chromatin remodelers and transcriptional regulators. AB - Members of the bromodomain and extra-terminal domain (BET) family of proteins (bromodomain-containing (BRD) 2, 3, 4, and T) are widely expressed and highly conserved regulators of gene expression in eukaryotes. These proteins have been intimately linked to human disease, and more than a dozen clinical trials are currently underway to test BET-protein inhibitors as modulators of cancer. However, although it is clear that these proteins use their bromodomains to bind both histones and transcription factors bearing acetylated lysine residues, the molecular mechanisms by which BET family proteins regulate gene expression are not well defined. In particular, the functions of the other domains such as the ET domain have been less extensively studied. Here, we examine the properties of the ET domain of BRD3 as a protein/protein interaction module. Using a combination of pulldown and biophysical assays, we demonstrate that BRD3 binds to a range of chromatin-remodeling complexes, including the NuRD, BAF, and INO80 complexes, via a short linear "KIKL" motif in one of the complex subunits. NMR based structural analysis revealed that, surprisingly, this mode of interaction is shared by the AF9 and ENL transcriptional coregulators that contain an acetyl lysine-binding YEATS domain and regulate transcriptional elongation. This observation establishes a functional commonality between these two families of cancer-related transcriptional regulators. In summary, our data provide insight into the mechanisms by which BET family proteins might link chromatin acetylation to transcriptional outcomes and uncover an unexpected functional similarity between BET and YEATS family proteins. PMID- 29567838 TI - Group I chitin deacetylases are essential for higher order organization of chitin fibers in beetle cuticle. AB - Roles in the organization of the cuticle (exoskeleton) of two chitin deacetylases (CDAs) belonging to group I, TcCDA1 and TcCDA2, as well as two alternatively spliced forms of the latter, TcCDA2a and TcCDA2b, from the red flour beetle, Tribolium castaneum, were examined in different body parts using transmission EM and RNAi. Even though all TcCDAs are co-expressed in cuticle-forming cells from the hardened forewing (elytron) and ventral abdomen, as well as in the softer hindwing and dorsal abdomen, there are significant differences in the tissue specificity of expression of the alternatively spliced transcripts. Loss of either TcCDA1 or TcCDA2 protein by RNAi causes abnormalities in organization of chitinous horizontal laminae and vertical pore canals in all regions of the procuticle of both the hard and soft cuticles. Simultaneous RNAi for TcCDA1 and TcCDA2 produces the most serious abnormalities. RNAi of either TcCDA2a or TcCDA2b affects cuticle integrity to some extent. Following RNAi, there is accumulation of smaller disorganized fibers in both the horizontal laminae and pore canals, indicating that TcCDAs play a critical role in elongation/organization of smaller nanofibers into longer fibers, which is essential for structural integrity of both hard/thick and soft/thin cuticles. Immunolocalization of TcCDA1 and TcCDA2 proteins and effects of RNAi on their accumulation indicate that these two proteins function in concert exclusively in the assembly zone in a step involving the higher order organization of the procuticle. PMID- 29567839 TI - Concurrent drug use among methadone maintenance patients in mountainous areas in northern Vietnam. AB - OBJECTIVES: With the rise in methadone maintenance therapy (MMT) for drug users in Vietnam, there has been growing interest in understanding if and how often MMT patients engage in concurrent illicit drug use while on methadone therapy in various settings. This study examined factors associated with concurrent opioid use among patients on MMT in a mountainous area in Vietnam. SETTING: One urban and one rural MMT clinics in Tuyen Quang province. PARTICIPANTS: Survey participants consisted of patients who were taking MMT at the selected study sites. A convenience sampling approach was used to recruit the participants. PRIMARY AND SECONDARY OUTCOME MEASURES: Participants were asked a series of questions about their socioeconomic status, current alcohol and tobacco use, health problems (measured by the EuroQol-Five Dimension-Five Level instrument), psychological distress (measured by Kessler score), and factors associated with current and/or previous drug use. Regression models were used to determine factors associated with concurrent drug use among MMT patients. RESULTS: Among the 241 male MMT patients included in the study, 13.4% reported concurrent opioid use. On average, the longer patients had been enrolled in MMT, the less likely they were to concurrently use drugs. Conversely, patients with higher levels of psychological distress were more likely to engage in concurrent drug use while on MMT. CONCLUSION: Longer duration of MMT was significantly correlated with reduced illicit drug use among participants. Higher levels of psychological distress were associated with increased use of illicit drugs among MMT patients. Regardless of distance, long-term MMT is still effective and should be expanded in mountainous areas. PMID- 29567840 TI - Motivation and main flavour of use, use with nicotine and dual use of electronic cigarettes in Barcelona, Spain: a cross-sectional study. AB - OBJECTIVE: This study seeks to describe current e-cigarette users' patterns of use including primary motivation for use, dual use, use with nicotine and principal flavour used, according to individuals' sociodemographic characteristics and conventional tobacco consumption in Barcelona, Spain. DESIGN, SETTING AND PARTICIPANTS: This is a cross-sectional study of adult (>=18) current e-cigarette users of Barcelona (n=600), recruited in 2015. Researchers calculated percentages and ORs with their 95% CIs of users' e-cigarette use with nicotine, primary motivation for use and preferred flavour. The analyses were stratified by sociodemographic variables including sex, age and level of education and by patterns of e-cigarette use and past and current conventional tobacco use. RESULTS: The most prevalent motivation for using e-cigarettes was to reduce tobacco smoking (48%, n=288), followed by quitting smoking (39.2%, n=235), and to use e-cigarettes in places where tobacco smoking was prohibited (10.2%, n=61). The most prevalent primary flavour used was tobacco (49%, n=294), followed by fruit (19.5%, n=117). People younger than 25 years old (OR=4.36, 95% CI 1.99 to 9.57) were more likely than older people to use them where smoking cigarettes was prohibited. A greater proportion of those in the youngest age group preferred fruit flavour compared with older individuals (29.3%, n=41). CONCLUSIONS: Younger users of e-cigarettes and non-smokers are more likely to use flavours other than tobacco and to use e-cigarettes mainly for recreational purposes. PMID- 29567841 TI - Association of socioeconomic status with financial burden of disease among elderly patients with cardiovascular disease: evidence from the China Health and Retirement Longitudinal Survey. AB - OBJECTIVES: The prevalence of cardiovascular diseases (CVD) within low-income and middle-income countries has reached epidemic proportions. However, the association between out-of-pocket (OOP) payment and socioeconomic status (SES) of patients with CVD is not well studied. We aimed to understand the financial burden among Chinese middle-aged and older patients with CVD, and whether there was an association with SES. SETTINGS: A nationally representative survey-The China Health and Retirement Longitudinal Survey (CHARLS)-was conducted in 28 provinces of mainland China in 2011 and 2013. PARTICIPANTS: Of the over 18 000 CHARLS respondents, eligible participants were those aged 45 years and over who had been previously diagnosed with CVD. OUTCOME MEASURES: Financial burden was measured by individual OOP payment and household catastrophic health expenditure (CHE) occurrence (ie, the annual household health expenditure was 40% or more of the total non-food household expenditure). Multilevel regression models were used to explore the association between financial burden and SES. RESULTS: Among CHARLS respondents, CVD prevalence increased from 14.7% in 2011 to 16.6% in 2013. Average annual CVD OOP payment increased from 5000 RMB (770 USD) to 6120 RMB (970 USD). Furthermore, CHE occurrence increased from 44.2% to 48.1%. Patients spent almost twice on outpatient as on inpatient services. Two of the three SES indicators (total household expenditure, occupation type) were found to be associated with CVD OOP payment amount, and the likelihood of CHE. Unemployed patients had a higher likelihood of CHE compared with agricultural workers. Rural urban difference was associated with the likelihood of CHE in 2011 alone. CONCLUSION: The Chinese health system should use this health expenditure pattern among patients with CVD to create more equitable health insurance schemes that financially balance between outpatient and inpatient care, and provide better financial risk protection to patients with low SES. PMID- 29567842 TI - Prevalence of potentially inappropriate prescribing in a subpopulation of older European clinical trial participants: a cross-sectional study. AB - OBJECTIVES: To estimate and compare the prevalence and type of potentially inappropriate prescribing (PIP) and potential prescribing omissions (PPOs) among community-dwelling older adults (>=65 years) enrolled to a clinical trial in three European countries. DESIGN: A secondary analysis of the Thyroid Hormone Replacement for Subclinical Hypothyroidism Trial dataset. PARTICIPANTS: A subset of 48/80 PIP and 22/34 PPOs indicators from the Screening Tool of Older Persons Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) V2 criteria were applied to prescribed medication data for 532/737 trial participants in Ireland, Switzerland and the Netherlands. RESULTS: The overall prevalence of PIP was lower in the Irish participants (8.7%) compared with the Swiss (16.7%) and Dutch (12.5%) participants (P=0.15) and was not statistically significant. The overall prevalence of PPOs was approximately one-quarter in the Swiss (25.3%) and Dutch (24%) participants and lower in the Irish (14%) participants (P=0.04) and the difference was statistically significant. The hypnotic Z-drugs were the most frequent PIP in Irish participants, (3.5%, n=4), while it was non-steroidal anti-inflammatory drug and oral anticoagulant combination, sulfonylureas with a long duration of action, and benzodiazepines (all 4.3%, n=7) in Swiss, and benzodiazepines (7.1%, n=18) in Dutch participants. The most frequent PPOs in Irish participants were vitamin D and calcium in osteoporosis (3.5%, n=4). In the Swiss and Dutch participants, they were bone antiresorptive/anabolic therapy in osteoporosis (9.9%, n=16, 8.6%, n=22) respectively. The odds of any PIP after adjusting for age, sex, multimorbidity and polypharmacy were (adjusted OR (aOR)) 3.04 (95% CI 1.33 to 6.95, P<0.01) for Swiss participants and aOR 1.74 (95% CI 0.79 to 3.85, P=0.17) for Dutch participants compared with Irish participants. The odds of any PPOs were aOR 2.48 (95% CI 1.27 to 4.85, P<0.01) for Swiss participants and aOR 2.10 (95% CI 1.11 to 3.96, P=0.02) for Dutch participants compared with Irish participants. CONCLUSIONS: This study has estimated and compared the prevalence and type of PIP and PPOs among this cohort of community-dwelling older people. It demonstrated a significant difference in the prevalence of PPOs between the three populations. Further research is urgently needed into the impact of system level factors as this has important implications for patient safety, healthcare provision and economic costs. PMID- 29567843 TI - A novel inpatient complex pain team: protocol for a mixed-methods evaluation of a single-centre pilot study. AB - INTRODUCTION: Complex pain is a debilitating condition that is responsible for low quality of life and significant economic impacts. Although best practice in the treatment of complex pain employs a multidisciplinary team, many patients do not have access to this care, leading to poor outcomes. METHODS AND ANALYSIS: This study evaluates a novel inpatient complex pain team at a large London teaching hospital. A multidisciplinary pain team comprising specialist doctors, nurses, psychologists and physiotherapists was instituted for inpatients with complex pain who will undergo an intense and bespoke evidence-based programme which will then be integrated into the community. A mixed-methods evaluation will take place and patients will be recruited over the course of 1 year. A qualitative arm will interview 15 staff and 15 patients on recruitment and again 6 months later looking to compare and contrast the new pain team with past experiences of pain management. A quantitative arm will assess clinical outcomes using validated scoring tools. An economic evaluation will seek to evaluate the relative cost of the service by comparing healthcare costs before and after the intervention. ETHICS AND DISSEMINATION: The study was categorised as a service evaluation, so formal ethical approval was not considered necessary. Participant recruitment began in January 2016 and the 1-year follow-up will end in November 2017. The results of this study will be published in 2018. PMID- 29567844 TI - Seroprevalence of antibodies against varicella zoster virus and rubella virus among newly recruited expatriate healthcare workers: a cross-sectional study. AB - OBJECTIVES: To assess the state of immunity to varicella zoster virus (VZV) and rubella virus (RV) among newly recruited healthcare workers (HCWs) in Kuwait before they begin work, and to determine whether there are differences in the prevalence of seronegativity according to nationality, gender, age group and occupation group. SETTING: This cross-sectional study involved analysis of blood samples from workers newly recruited to the Kuwaiti healthcare system. PARTICIPANTS: All new non- national HCWs recruited during the study period (n=1540). INTERVENTION: Enzyme-linked immunoassays for VZV-specific and RV specific IgG were performed. RESULTS: Among HCWs, 81.9% and 93.5% were immune to VZV and RV, respectively. Male seronegativity was higher than that of females for both viruses. Regarding VZV, the majority of seronegative individuals were Indians (23.5%), followed by Somalis (12.5), Filipinos (6.5) and Egyptians (5.4%); the between-group differences were significant for all groups. The age groups 20-30 and 30-40 years were most likely to be seronegative, with prevalences of 18.2% and 18.9%, respectively. VZV seronegativity was most common among nurses (21.1%) and least common among physicians (9.2%), and the difference was significant. In addition, RV seronegativity was most frequent among Somalis (12.5%) and lowest among Indians (5.3%); other nationalities (Egyptian, Filipino and others) ranged between 9.1% and 9.6%. Seronegative individuals were most frequently in the younger age group (<20 years old) (17.5%), followed by the >40 years old group (10.4%). RV seronegativity was highest among nurses (6.9%) and lowest among physicians (5.2%). CONCLUSION: The prevalence of seronegativity is highest among Indians for VZV and Somalis for RV, and HCWs aged 20-40 years for VZV and <20 years for RV. For both viruses, the seronegativity rate was highest for male HCWs, and for nurses compared with other HCWs, with physicians having the lowest prevalence of both viruses. PMID- 29567846 TI - Can a midwife-led continuity model improve maternal services in a low-resource setting? A non-randomised cluster intervention study in Palestine. AB - OBJECTIVES: To improve maternal health services in rural areas, the Palestinian Ministry of Health launched a midwife-led continuity model in the West Bank in 2013. Midwives were deployed weekly from governmental hospitals to provide antenatal and postnatal care in rural clinics. We studied the intervention's impact on use and quality indicators of maternal services after 2 years' experience. DESIGN: A non-randomised intervention design was chosen. The study was based on registry data only available at cluster level, 2 years before (2011and2012) and 2 years after (2014and2015) the intervention. SETTING: All 53 primary healthcare clinics in Nablus and Jericho regions were stratified for inclusion. PRIMARY AND SECONDARY OUTCOMES: Primary outcome was number of antenatal visits. Important secondary outcomes were number of referrals to specialist care and number of postnatal home visits. Differences in changes within the two groups before and after the intervention were compared by using mixed effect models. RESULTS: 14 intervention clinics and 25 control clinics were included. Number of antenatal visits increased by 1.16 per woman in the intervention clinics, while declined by 0.39 in the control clinics, giving a statistically significant difference in change of 1.55 visits (95% CI 0.90 to 2.21). A statistically significant difference in number of referrals was observed between the groups, giving a ratio of rate ratios of 3.65 (2.78-4.78) as number of referrals increased by a rate ratio of 3.87 in the intervention group, while in the control the rate ratio was only 1.06.Home visits increased substantially in the intervention group but decreased in the control group, giving a ratio of RR 97.65 (45.20 - 210.96) CONCLUSION: The Palestinian midwife-led continuity model improved use and some quality indicators of maternal services. More research should be done to investigate if the model influenced individual health outcomes and satisfaction with care. TRIAL REGISTRATION NUMBER: NCT03145571; Results. PMID- 29567845 TI - Association of dispositional optimism with Life's Simple 7's Cardiovascular Health Index: results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (SCAS). AB - OBJECTIVES: Mounting evidence links positive psychological functioning to restorative health processes and favourable medical outcomes. However, very little is known about the relationship between optimism, an indicator of psychological functioning and the American Heart Association (AHA)-defined concept of cardiovascular health (CVH), particularly in Hispanics/Latinos of diverse backgrounds. To address limitations of existing literature, this study investigated the association between dispositional optimism and CVH in a heterogeneous sample of Hispanics/Latinos residing in the USA. DESIGN: Cross sectional study. PARTICIPANTS AND SETTING: Data were analysed from 4919 adults ages 18-75 of the Hispanic Community Health Study/Study of Latinos parent study and the Sociocultural Ancillary Study. MAIN OUTCOME MEASURES: Optimism was assessed using the 6-item Life Orientation Test-Revised (range from 6 to 30). AHA classification standards were used to derive an additive CVH score with operationalisation of indicators as Ideal, Intermediate and Poor. The overall CVH score included indicators of diet, body mass index, physical activity, cholesterol, blood pressure, fasting glucose and smoking status. Multivariate linear and logistic regressions were used to examine associations of optimism with CVH (Life's Simple 7), after adjusting for sociodemographic factors and depressive symptoms. RESULTS: Each increase in the optimism total score was associated with a greater CVH score (beta=0.03 per unit increase, 95% CI 0.01 to 0.05). When modelling tertiles of optimism, participants with moderate (beta=0.24 to 95% CI 0.06 to 0.42) and high (beta=0.12, 95% CI 0.01 to 0.24) levels of optimism displayed greater CVH scores when compared with their least optimistic peers. CONCLUSION: This study offers preliminary evidence for an association between optimism and CVH in a large heterogeneous group of Hispanic/Latino adults. Our study adds scientific knowledge of psychological assets that may promote CVH and suggests a novel therapeutic target for consideration. Future studies are needed to explore causality and potential mechanism underlying the relationship between positive emotion and heart health. PMID- 29567847 TI - Reliability of coded data to identify earliest indications of cognitive decline, cognitive evaluation and Alzheimer's disease diagnosis: a pilot study in England. AB - OBJECTIVES: Evaluate the reliability of using diagnosis codes and prescription data to identify the timing of symptomatic onset, cognitive assessment and diagnosis of Alzheimer's disease (AD) among patients diagnosed with AD. METHODS: This was a retrospective cohort study using the UK Clinical Practice Research Datalink (CPRD). The study cohort consisted of a random sample of 50 patients with first AD diagnosis in 2010-2013. Additionally, patients were required to have a valid text-field code and a hospital episode or a referral in the 3 years before the first AD diagnosis. The earliest indications of cognitive impairment, cognitive assessment and AD diagnosis were identified using two approaches: (1) using an algorithm based on diagnostic codes and prescription drug information and (2) using information compiled from manual review of both text-based and coded data. The reliability of the code-based algorithm for identifying the earliest dates of the three measures described earlier was evaluated relative to the comprehensive second approach. Additionally, common cognitive assessments (with and without results) were described for both approaches. RESULTS: The two approaches identified the same first dates of cognitive symptoms in 33 (66%) of the 50 patients, first cognitive assessment in 29 (58%) patients and first AD diagnosis in 43 (86%) patients. Allowing for the dates from the two approaches to be within 30 days, the code-based algorithm's success rates increased to 74%, 70% and 94%, respectively. Mini-Mental State Examination was the most commonly observed cognitive assessment in both approaches; however, of the 53 tests performed, only 19 results were observed in the coded data. CONCLUSIONS: The code based algorithm shows promise for identifying the first AD diagnosis. However, the reliability of using coded data to identify earliest indications of cognitive impairment and cognitive assessments is questionable. Additionally, CPRD is not a recommended data source to identify results of cognitive assessments. PMID- 29567848 TI - Self-management interventions for adults with chronic kidney disease: a scoping review. AB - OBJECTIVE: To systematically identify and describe self-management interventions for adult patients with chronic kidney disease (CKD). SETTING: Community-based. PARTICIPANTS: Adults with CKD stages 1-5 (not requiring kidney replacement therapy). INTERVENTIONS: Self-management strategies for adults with CKD. PRIMARY AND SECONDARY OUTCOME MEASURES: Using a scoping review, electronic databases and grey literature were searched in October 2016 to identify self-management interventions for adults with CKD stages 1-5 (not requiring kidney replacement therapy). Randomised controlled trials (RCTs), non-RCTs, qualitative and mixed method studies were included and study selection and data extraction were independently performed by two reviewers. Outcomes included behaviours, cognitions, physiological measures, symptoms, health status and healthcare. RESULTS: Fifty studies (19 RCTs, 7 quasi-experimental, 5 observational, 13 pre post intervention, 1 mixed method and 5 qualitative) reporting 45 interventions were included. The most common intervention topic was diet/nutrition and interventions were regularly delivered face to face. Interventions were administered by a variety of providers, with nursing professionals the most common health professional group. Cognitions (ie, changes in general CKD knowledge, perceived self-management and motivation) were the most frequently reported outcome domain that showed improvement. Less than 1% of the interventions were co-developed with patients and 20% were based on a theory or framework. CONCLUSIONS: There was a wide range of self-management interventions with considerable variability in outcomes for adults with CKD. Major gaps in the literature include lack of patient engagement in the design of the interventions, with the majority of interventions not applying a behavioural change theory to inform their development. This work highlights the need to involve patients to co developed and evaluate a self-management intervention based on sound theories and clinical evidence. PMID- 29567849 TI - Diagnostic accuracy of self-administered urine glucose test strips as a diabetes screening tool in a low-resource setting in Cambodia. AB - OBJECTIVE: Screening for diabetes in low-resource countries is a growing challenge, necessitating tests that are resource and context appropriate. The aim of this study was to determine the diagnostic accuracy of a self-administered urine glucose test strip compared with alternative diabetes screening tools in a low-resource setting of Cambodia. DESIGN: Prospective cross-sectional study. SETTING: Members of the Borey Santepheap Community in Cambodia (Phnom Penh Municipality, District Dangkao, Commune Chom Chao). PARTICIPANTS: All households on randomly selected streets were invited to participate, and adults at least 18 years of age living in the study area were eligible for inclusion. OUTCOMES: The accuracy of self-administered urine glucose test strip positivity, Hemoglobin A1c (HbA1c)>6.5% and capillary fasting blood glucose (cFBG) measurement >=126 mg/dL were assessed against a composite reference standard of cFBGmeasurement >=200 mg/dL or venous blood glucose 2 hours after oral glucose tolerance test (OGTT) >=200 mg/dL. RESULTS: Of the 1289 participants, 234 (18%) had diabetes based on either cFBG measurement (74, 32%) or the OGTT (160, 68%). The urine glucose test strip was 14% sensitive and 99% specific and failed to identify 201 individuals with diabetes while falsely identifying 7 without diabetes. Those missed by the urine glucose test strip had lower venous fasting blood glucose, lower venous blood glucose 2 hours after OGTT and lower HbA1c compared with those correctly diagnosed. CONCLUSIONS: Low cost, easy to use diabetes tools are essential for low-resource communities with minimal infrastructure. While the urine glucose test strip may identify persons with diabetes that might otherwise go undiagnosed in these settings, its poor sensitivity cannot be ignored. The massive burden of diabetes in low-resource settings demands improvements in test technologies. PMID- 29567851 TI - Role of CHA2DS2-VASc score in predicting new-onset atrial fibrillation in patients with type 2 diabetes mellitus with and without hyperosmolar hyperglycaemic state: real-world data from a nationwide cohort. AB - PURPOSE: The objective of the current study was to explore the role of CHA2DS2 VASc score in predicting incidence of atrial fibrillation (AF) in patients with type 2 diabetes mellitus (DM). Furthermore, the use of the CHA2DS2-VASc score for stratifying new-onset AF risk in patients with DM and with/without hyperosmolar hyperglycaemic state (HHS) was also compared. METHODS: The study subjects were identified from Longitudinal Health Insurance Database provided by the National Health Research Institutes. The patients with DM were divided into two groups based on a history of HHS or not. The predictive ability of CHA2DS2-VASc score for stratifying new-onset AF risk in the two groups was calculated using the area under the curve of receiver-operating characteristic (AUROC). RESULTS: The present study involved a total of 69 530 patients with type 2 DM. Among them, 1558 patients had a history of HHS, whereas 67 972 patients did not. The AUROC of the CHA2DS2-VASc score as a predictor of incident AF in patients with DM and with/without HHS was 0.67 (95% CI 0.59 to 0.75) and 0.71 (95% CI 0.70 to 0.72), respectively. CONCLUSIONS: To conclude, we reported for the first time on the assessment of CHA2DS2-VASc score for incident AF risk discrimination in patients with type 2 DM. We further found that the predictive ability of the CHA2DS2-VASc score was attenuated in patients with type 2 DM and with HHS in comparison with those without HHS. PMID- 29567850 TI - Levels of detection of hypertension in primary medical care and interventions to improve detection: a systematic review of the evidence since 2000. AB - OBJECTIVES: In England, many hypertensives are not detected by primary medical care. Higher detection is associated with lower premature mortality. We aimed to summarise recent evidence on detection and interventions to improve detection in order to inform policies to improve care. DESIGN: Data sources: systematic review of articles published since 2000. Searches of Medline and Embase were undertaken. Eligibility criteria: published in English, any study design, the setting was general practice and studies included patients aged 18 or over. EXCLUSION CRITERIA: screening schemes, studies in primary care settings other than general practice, discussion or comment pieces. PARTICIPANTS: adult patients of primary medical care services. SYNTHESIS: study heterogeneity precluded a statistical synthesis, and papers were described in summary tables. RESULTS: Seventeen quantitative and one qualitative studies were included. Detection rates varied by gender and ethnic group, but longitudinal studies indicated an improvement in detection over time. Patient socioeconomic factors did not influence detection, but living alone was associated with lower detection. Few health system factors were associated with detection, but in two studies higher numbers of general practitioners per 1000 population were associated with higher detection. Three studies investigated interventions to improve detection, but none showed evidence of effectiveness. LIMITATIONS: The search was limited to studies published from 2000, in English. There were few studies of interventions to improve detection, and a meta-analysis was not possible. CONCLUSIONS AND IMPLICATIONS: Levels of detection of hypertension by general practices may be improving, but large numbers of people with hypertension remain undetected. Improvement in detection is therefore required, but guidance for primary medical care is not provided by the few studies of interventions included in this review. Primary care teams should continue to use low-cost, practical approaches to detecting hypertension until evidence from new studies of interventions to improve detection is available. PMID- 29567852 TI - Effects of supplementation with carnosine and other histidine-containing dipeptides on chronic disease risk factors and outcomes: protocol for a systematic review of randomised controlled trials. AB - INTRODUCTION: Ageing of populations globally, coupled with the obesity epidemic, has resulted in the rising prevalence of chronic diseases including diabetes, cardiovascular diseases, cancers and neurodegenerative disorders. Prevention of risk factors that contribute to these diseases is key in managing the global burden of chronic diseases. Recent studies suggest that carnosine, a dipeptide with anti-inflammatory, antioxidative and antiglycating properties may have a role in the prevention of chronic diseases; however, no previous reviews have examined the effects of carnosine and other histidine-containing peptides (HCDs) on chronic disease risk factors and outcomes. We aim to conduct a comprehensive systematic review to examine the effects of supplementation with carnosine and other HCDs on chronic disease risk factors and outcomes and to identify relevant knowledge gaps. METHODS AND ANALYSIS: Electronic databases including Medline, Cumulative Index of Nursing and Allied Health, Embase and all Evidence-Based Medicine will be systematically searched to identify randomised controlled trials (RCTs) and systematic reviews of RCTs, comparing supplementation with carnosine and/or other HCDs versus placebo, usual care or other pharmacological or non pharmacological interventions. One reviewer will screen titles and abstracts for eligibility according to prespecified inclusion criteria, after which two independent reviewers will perform data extraction and quality appraisal. Meta analyses, metaregression and subgroup analyses will be conducted where appropriate. ETHICS AND DISSEMINATION: Ethics approval is not required as this review does not involve primary data collection. This review will generate level one evidence regarding the effects of carnosine supplementation on chronic disease risk factors and outcomes and will be disseminated through peer-reviewed publications and at conference meetings to inform future research on the efficacy of carnosine supplementation for the prevention of chronic diseases.

AB - OBJECTIVES: To explore the roles of community cadres in improving access to and retention in care for PMTCT (prevent mother-to-child transmission of HIV) services in the context of PMTCT Option B+ treatment scale-up in high burden low income and lower-middle income countries. DESIGN/METHODS: Qualitative rapid appraisal study design using semistructured in-depth interviews and focus group discussions (FGDs) between 8 June and 31 July 2015. SETTING AND PARTICIPANTS: Interviews were conducted in the offices of Ministry of Health Staff, Implementing partners, district offices and health facility sites across four low income and lower-middle income countries: Cote D'Ivoire, Democratic Republic of Congo (DRC), Malawi and Uganda. A range of individual interviews and FGDs with key stakeholders including Ministry of Health employees, Implementation partners, district management teams, facility-based health workers and community cadres. A total number of 18, 28, 31 and 83 individual interviews were conducted in Malawi, Cote d'Ivoire, DRC and Uganda, respectively. A total number of 15, 9, 10 and 16 mixed gender FGDs were undertaken in Malawi, Cote d'Ivoire, DRC and Uganda, respectively. RESULTS: Community cadres either operated solely in the community, worked from health centres or in combination and their mandates were PMTCT specific or included general HIV support and other health issues. Community cadres included volunteers, those supported by implementing partners or employed directly by the Ministry of Health. Their complimentary roles along the continuum of HIV care and treatment include demand creation, household mapping of pregnant and lactating women, linkage to care, infant follow-up and adherence and retention support. CONCLUSIONS: Community cadres provide an integral link between communities and health facilities, supporting overstretched health workers in HIV client support and follow-up. However, their role in health systems is neither standardised nor systematic and there is an urgent need to invest in the standardisation of and support to community cadres to maximise potential health impacts. PMID- 29567855 TI - Deubiquitylases USP5 and USP13 are recruited to and regulate heat-induced stress granules through their deubiquitylating activities. AB - Stress granules are transient cytoplasmic foci induced by various stresses that contain translation-stalled mRNAs and RNA-binding proteins. They are proposed to modulate mRNA translation and stress responses. Here, we show that the deubiquitylases USP5 and USP13 are recruited to heat-induced stress granules. Heat-induced stress granules also contained K48- and K63-linked ubiquitin chains. Depletion of USP5 or USP13 resulted in elevated ubiquitin chain levels and accelerated assembly of heat-induced stress granules, suggesting that these enzymes regulate the stability of the stress granules through their ubiquitin isopeptidase activity. Moreover, disassembly of heat-induced stress granules after returning the cells to normal temperatures was markedly repressed by individual depletion of USP5 or USP13. Finally, overexpression of a ubiquitin mutant lacking the C-terminal diglycine motif caused the accumulation of unanchored ubiquitin chains and the repression of the disassembly of heat-induced stress granules. As unanchored ubiquitin chains are preferred substrates for USP5, we suggest that USP5 regulates the assembly and disassembly of heat-induced stress granules by mediating the hydrolysis of unanchored ubiquitin chains while USP13 regulates stress granules through deubiquitylating protein-conjugated ubiquitin chains.This article has an associated First Person interview with the first author of the paper. PMID- 29567854 TI - Risk factors of asthma exacerbation based on asthma severity: a nationwide population-based observational study in South Korea. AB - OBJECTIVES: Asthma exacerbation, associated with many risks factors, can reflect management failure. However, little is known about how risk factors are associated with exacerbation, according to asthma severity. We aimed to investigate differences in risk factors in patients with different asthma severity and evaluate whether risk factors differed between frequent exacerbators and patients with single exacerbation. DESIGN: Nationwide population-based observational study. SETTING: Korean National Sample Cohort database. PARTICIPANTS: We included 22 130 adults with asthma diagnoses more than twice (ICD-10 (International Classification of Diseases, Tenth revision) codes J45 and J46) and one prescription for asthma medication from 2010 to 2011. OUTCOME MEASURES: Asthma exacerbation was defined as having a corticosteroid (CS) burst characterised by a prescription of high-dose oral CS for >=3 days or one systemic CS injection, hospitalisation or emergency department visit. RESULTS: Among severities, history of CS bursts was significantly associated with exacerbation. In mild and moderate asthma, exacerbation was significantly associated with age >=45 years, being female, gastro-oesophageal reflux disease and chronic rhinitis. High medication possession ratio (MPR>=50%), compared with low MPR (<20%) showed adjusted ORs of 0.828 (95% CI 0.707 to 0.971) and 0.362 (0.185 to 0.708) in moderate and severe asthma, respectively. In severe asthma, compared with mild asthma, only allergic rhinitis and history of hospitalisation were strongly associated with exacerbation. When comparing frequent exacerbators to patients with single exacerbation, age >=45 years, atopic dermatitis, anxiety and history of CS burst were significant risk factors in mild and moderate asthma, whereas no risk factors were significant in severe asthma. CONCLUSIONS: Different associations between risk factors and asthma exacerbations based on asthma severity suggest that patients with mild asthma require greater attention to their age and comorbidities, whereas those with severe asthma require greater attention to hospitalisation history and drug adherence. PMID- 29567856 TI - Genetic dissection of the phosphoinositide cycle in Drosophila photoreceptors. AB - Phototransduction in Drosophila is mediated by phospholipase C-dependent hydrolysis of PIP2-, and is an important model for phosphoinositide signalling. Although generally assumed to operate by generic machinery conserved from yeast to mammals, some key elements of the phosphoinositide cycle have yet to be identified in Drosophila photoreceptors. Here, we used transgenic flies expressing fluorescently tagged probes (P4M and TbR332H), which allow in vivo quantitative measurements of PI4P and PIP2 dynamics in photoreceptors of intact living flies. Using mutants and RNA interference for candidate genes potentially involved in phosphoinositide turnover, we identified Drosophila PI4KIIIalpha (CG10260) as the PI4-kinase responsible for PI4P synthesis in the photoreceptor membrane. Our results also indicate that PI4KIIIalpha activity requires rbo (the Drosophila orthologue of Efr3) and CG8325 (orthologue of YPP1), both of which are implicated as scaffolding proteins necessary for PI4KIIIalpha activity in yeast and mammals. However, our evidence indicates that the recently reported central role of dPIP5K59B (CG3682) in PIP2 synthesis in the rhabdomeres should be re evaluated; although PIP2 resynthesis was suppressed by RNAi directed against dPIP5K59B, little or no defect was detected in a reportedly null mutant (dPIP5K18 ). PMID- 29567857 TI - Targeting Brain-Adaptive Cancer Stem Cells Prohibits Brain Metastatic Colonization of Triple-Negative Breast Cancer. AB - Triple-negative breast cancer (TNBC) exhibits more traits possessed by cancer stem cells (CSC) than other breast cancer subtypes and is more likely to develop brain metastases. TNBC patients usually have shorter survival time after diagnosis of brain metastasis, suggesting an innate ability of TNBC tumor cells in adapting to the brain. In this study, we establish novel animal models to investigate early tumor adaptation in brain metastases by introducing both patient-derived and cell line-derived CSC-enriched brain metastasis tumorsphere cells into mice. We discovered astrocyte-involved tumor activation of protocadherin 7 (PCDH7)-PLCbeta-Ca2+-CaMKII/S100A4 signaling as a mediator of brain metastatic tumor outgrowth. We further identified and evaluated the efficacy of a known drug, the selective PLC inhibitor edelfosine, in suppressing the PCDH7 signaling pathway to prohibit brain metastases in the animal models. The results of this study reveal a novel signaling pathway for brain metastases in TNBC and indicate a promising strategy of metastatic breast cancer prevention and treatment by targeting organ-adaptive cancer stem cells.Significance: These findings identify a compound to block adaptive signaling between cancer stem cells and brain astrocytes.

PMID- 29567858 TI - Serum Bicarbonate Concentration and Cognitive Function in Hypertensive Adults. AB - BACKGROUND AND OBJECTIVES: Cognitive function worsens as kidney function declines, but mechanisms contributing to this association are not completely understood. Metabolic acidosis, a common complication of CKD, leads to neural networks overexcitation and is involved in cerebral autoregulation. We aimed to evaluate the association between serum bicarbonate concentration as a measure of metabolic acidosis, and cognitive function in hypertensive adults with and without CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Five cognitive summary scores were measured (global cognitive function, executive function, memory, attention/concentration, and language) in 2853 participants in the Systolic BP Intervention Trial (SPRINT). Multivariable linear regression models adjusted for demographics, comorbidities, systolic BP, medications, eGFR and albuminuria evaluated the cross-sectional association between bicarbonate and cognition at SPRINT baseline. In a subset (n=681) who underwent brain magnetic resonance imaging, the models were adjusted for white matter hyperintensity volume, vascular reactivity, and cerebral blood flow. RESULTS: The mean age (SD) was 68 (8.5) years. Global cognitive and executive functions were positively associated with serum bicarbonate (estimate [SEM]: 0.014 [0.006]; P=0.01, and 0.018 [0.006]; P=0.003, respectively). Each 1 mEq/L lower bicarbonate level had a similar association with global cognitive and executive function as being 4.3 and 5.4 months older, respectively. The association with global cognition persisted after magnetic resonance imaging findings adjustment (estimate [SEM]: 0.03 [0.01]; P=0.01). There was no association between serum bicarbonate level and memory, attention/concentration, and language. CONCLUSIONS: In a large cohort of hypertensive adults, higher serum bicarbonate levels were independently associated with better global cognitive and executive performance.

PMID- 29567864 TI - Systems Thinking and Leadership: How Nephrologists Can Transform Dialysis Safety to Prevent Infections. AB - Infections are the second leading cause of death for patients with ESKD. Despite multiple efforts, nephrologists have been unable to prevent infections in dialysis facilities. The American Society of Nephrology and the Centers for Disease Control and Prevention have partnered to create Nephrologists Transforming Dialysis Safety to promote nephrologist leadership and engagement in efforts to "Target Zero" preventable dialysis infections. Because traditional approaches to infection control and prevention in dialysis facilities have had limited success, Nephrologists Transforming Dialysis Safety is reconceptualizing the problem in the context of the complexity of health care systems and organizational behavior. By identifying different parts of a problem and attempting to understand how these parts interact and produce a result, systems thinking has effectively tackled difficult problems in dynamic settings. The dialysis facility is composed of different physical and human elements that are interconnected and affect not only behavior but also, the existence of a culture of safety that promotes infection prevention. Because dialysis infections result from a complex system of interactions between caregivers, patients, dialysis organizations, and the environment, attempts to address infections by focusing on one element in isolation often fail. Creating a sense of urgency and commitment to eradicating dialysis infections requires leadership and motivational skills. These skills are not taught in the standard nephrology or medical director curriculum. Effective leadership by medical directors and engagement in infection prevention by nephrologists are required to create a culture of safety. It is imperative that nephrologists commit to leadership training and embrace their potential as change agents to prevent infections in dialysis facilities. This paper explores the systemic factors contributing to the ongoing dialysis infection crisis in the United States and the role of nephrologists in instilling a culture of safety in which infections can be anticipated and prevented. PMID- 29567865 TI - Indomethacin Enhances Brown Fat Activity. AB - Indomethacin, a nonsteroidal anti-inflammatory drug, has been shown to induce white adipocyte differentiation; however, its roles in brown adipocyte differentiation and activation in brown adipose tissue (BAT) and obesity are unknown. To address this issue, we treated mouse brown preadipocytes with different doses of indomethacin, and delivered indomethacin to interscapular BAT (iBAT) of obese mice using implanted osmotic pumps. Indomethacin dose dependently increased brown preadipocyte differentiation and upregulated both mRNA and protein expression of uncoupling protein 1 (UCP1) and peroxisome proliferator activated receptor (PPAR) gamma coactivator 1-alpha. The mechanistic study showed that indomethacin significantly activated the reporter driven by the PPAR response element, indicating that indomethacin may work as a PPARgamma agonist in this cell line. Consistently, indomethacin significantly decreased iBAT mass and fasting blood glucose levels in high-fat diet-induced obesity (DIO) mice. Histologic analysis showed that brown adipocytes of indomethacin-treated mice contained smaller lipid droplets compared with control mice, suggesting that indomethacin alleviated the whitening of BAT induced by the high-fat diet. Moreover, indomethacin significantly increased UCP1 mRNA expression in iBAT. Taken together, this study indicates that indomethacin can promote mouse brown adipocyte differentiation, and might increase brown fat and glucose oxidation capacity in DIO mice.

PMID- 29567866 TI - Kruppel homolog 1 represses insect ecdysone biosynthesis by directly inhibiting the transcription of steroidogenic enzymes. AB - In insects, juvenile hormone (JH) and the steroid hormone ecdysone have opposing effects on regulation of the larval-pupal transition. Although increasing evidence suggests that JH represses ecdysone biosynthesis during larval development, the mechanism underlying this repression is not well understood. Here, we demonstrate that the expression of the Kruppel homolog 1 (Kr-h1), a gene encoding a transcription factor that mediates JH signaling, in ecdysone-producing organ prothoracic gland (PG) represses ecdysone biosynthesis by directly inhibiting the transcription of steroidogenic enzymes in both Drosophila and Bombyx Application of a JH mimic on ex vivo cultured PGs from Drosophila and Bombyx larvae induces Kr-h1 expression and inhibits the transcription of steroidogenic enzymes. In addition, PG-specific knockdown of Drosophila Kr-h1 promotes-while overexpression hampers-ecdysone production and pupariation. We further find that Kr-h1 inhibits the transcription of steroidogenic enzymes by directly binding to their promoters to induce promoter DNA methylation. Finally, we show that Kr-h1 does not affect DNA replication in Drosophila PG cells and that the reduction of PG size mediated by Kr-h1 overexpression can be rescued by feeding ecdysone. Taken together, our data indicate direct and conserved Kr-h1 repression of insect ecdysone biosynthesis in response to JH stimulation, providing insights into mechanisms underlying the antagonistic roles of JH and ecdysone. PMID- 29567868 TI - [Surgical Resection of Metastatic Brain Tumors:Risk of Local Recurrence and Leptomeningeal Dissemination, and Implications for Individualized Treatment]. AB - Metastatic brain tumors are important complications in the overall management of cancers. We sought to determine the risk of local recurrence and leptomeningeal carcinomatosis(LC)in patients treated with surgical resection and adjuvant radiation therapy. We retrospectively reviewed 173 consecutive patients with metastatic brain tumors managed by surgical resection between 2002 and 2015 in a single institution. Eighty-seven percent of the patients underwent postoperative adjuvant radiotherapy. The median overall survival from surgery was 9.8 months. Thirty of 173 patients(17.3%)developed local recurrence and 14(8.1%)developed LC following surgery. Male sex(hazard ratio(HR): 2.8, 95% confidence interval(CI): 1.0-10.0), colon cancer(HR: 6.5, 95% CI: 2.2-24.2), and no postoperative radiation(HR: 5.6, 95% CI: 2.1-13.7)were identified as risk factors of local recurrence in multivariate analysis. Female sex(HR: 4.4, 95% CI: 1.2-20.9)and recursive partitioning analysis(RPA)class 3(HR: 1.0e+9, 95%CI: 1.7-)were identified as risk factors of LC in multivariate analysis. Our retrospective review showed that individualized treatment with surgical resection followed by adjuvant radiation therapy is a safe and feasible method to control metastatic brain tumors in the real world.

However, CFD analysis still requires high costs and substantial time even now. This study aimed to evaluate whether newly developed software can shorten the time for analysis and serve useful information during clipping surgery for intracranial aneurysms. METHODS: CFD analysis was performed in 55 unruptured cerebral aneurysms in 51 patients. The time required for analysis of each aneurysm was recorded. On the basis of CFD analysis, both pressure and wall shear stress(WSS)were calculated as the values at the systolic and diastolic phases, and also the mean value through one cardiac cycle. These data were compared between thin-wall points and other points within each aneurysm. RESULTS: The average time required for analysis was 3 hours, ranging from 1 to 15 hours. The CFD data could be referenced during surgery in each patient. The pressure in about 93% and 80% of the thin-wall points was higher than that at other points within each aneurysm in the systolic and diastolic phases, respectively. However, there was no significant correlation between WSS and wall thickness in each aneurysm. CONCLUSION: This study clearly shows that newly-developed software is simple and requires much shorter time for CFD analysis than previous methods. Higher pressure through the cardiac cycle may efficiently predict a thin-wall region within intracranial aneurysms, which strongly suggests that CFD analysis would be a valuable tool to determine the treatment strategy in patients with unruptured aneurysms.

AB - Blister-like aneurysms(BLA)are morphologically thin-walled fragile structures that are associated with a high risk of intraoperative rupture. BLAs presumably originate from an arterial dissection and often stem from a non-branching site on the supraclinoid segment of the internal carotid artery. We report a rare case of a patient who was successfully treated for a ruptured BLA originating from the anterior communicating artery(Acom). A 60-year-old woman presented with severe headache and loss of consciousness. Computed tomography(CT)showed diffuse subarachnoid hemorrhage(SAH), which was observed to be particularly dense in the interhemispheric fissure around the Acom. CT angiography and three dimensional digital subtraction angiography(DSA)did not show any aneurysms along the Acom. Follow-up DSA performed on day 13 showed a small aneurysmal dilatation of the Acom, which was surgically treated via interhemispheric approach. Intraoperatively, a BLA observed to be originating from the Acom was wrapped with a piece of temporal fascia using fibrin glue. Postoperatively, this patient showed a good clinical course without re-rupture. Follow-up DSA performed 5 months after the occurrence of the SAH demonstrated disappearance of the BLA originating from the Acom. The findings in this patient strongly suggest that the pathomechanism of BLAs is attributable to an arterial dissection, which can often show morphological changes on short-term angiographic follow-up, and they demonstrate spontaneous repair. Thus, the therapeutic strategy to be utilized for the management of a BLA of the Acom should be carefully considered, because aneurysmal neck clipping or trapping can injure the Acom perforators and cause cognitive deficits. Further studies are needed to establish the optimal treatment strategy for the management of BLAs of the Acom.

AB - Epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKIs)are used as first-line treatment for patients with EGFR-mutated non-small cell lung cancer(NSCLC). Afatinib, a second-generation EGFR-TKI, is also effective against central nervous system(CNS)metastasis of NSCLC. However, patients treated with EGFR-TKI for many months may be at an increased risk of CNS metastasis due to the development of resistance in tumor cells to EGFR-TKI. The average period for development of resistance to EGFR-TKI is 8 to 10 months after the initiation of treatment. In the case presented herein, NSCLC showed a good clinical course in the 10 months following the initiation of afatinib;however, CNS metastasis progressed and presented unique findings on MR images. The lesions consisted of multiple cyst-like masses without gadolinium enhancement in the cerebellum and brain stem. The patient died within 2 months of the diagnosis of CNS metastasis. The resistance of tumor cells to afatinib may have occurred in the 10 months following the initiation of the treatment. Thus, CNS metastasis of NSCLC treated with afatinib may develop over a period of many months, exhibiting unique MRI findings, and deteriorate rapidly in some cases. PMID- 29567872 TI - [Tentorial Dural Arteriovenous Fistula Presenting with Ocular Symptoms:A Case Report]. AB - Tentorial dural arteriovenous fistula(dAVF)is classified as Cognard 4 with a high risk of aggressive feature, such as intracranial hemorrhage, venous infarction, and intracranial hypertension. We report a rare case presenting with ocular symptoms caused by tentorial dAVF. A 59-year-old man presented with progressive chemosis and exophthalmos of his left eye. Angiography showed a tentorial dAVF that was primarily fed by the middle meningeal artery and the meningohypophyseal artery. The AVF drained into the superior ophthalmic vein and the cerebellar cortical vein via an enlarged petrosal vein. Because transarterial Onyx embolization resulted in incomplete obliteration of the fistula, he underwent microsurgery via a suboccipital approach to obliterate the shunt. Postoperative angiography showed complete obliteration of the shunt. His ocular symptoms rapidly cured. We present this rare case and discuss the pathomechanism associated with the development of ocular symptoms secondary to a tentorial dAVF from the viewpoint of microvascular anatomy.

AB - INTRODUCTION: Decompressive craniectomy(DC)with craniotomy for acute epidural hematoma(AEDH)removal is controversial. Here, we summarized two difficult AEDH cases where DC was performed. CASE 1:A 26-year-old man sustained a head injury in a bicycle accident, with a Japan Coma Scale(JCS)score of 200, right pupil mydriasis, and a left decerebrate posture on admission. Computed tomography(CT)revealed right AEDH with a midline shift. Craniotomy was performed without DC. Postoperatively, his consciousness level and anisocoria improved(JCS score, 30). Furthermore, no cerebral infarction was observed on CT at 9 h after surgery;however, at 48 h after surgery, a cerebral infarction with a mild midline shift was evident in the right hemisphere. His consciousness level deteriorated(JCS score, 100), and we initiated glyceol infusion. Worsening of the midline shift was apparent on CT 100 h after surgery;thus, DC was immediately performed. CASE 2:A 15-year-old boy was injured in a fall. On admission, his JCS score was 10. Immediately afterward, he showed neurological deterioration(JCS score, 200), right pupil mydriasis, and a left decorticate posture. CT revealed right AEDH with a midline shift;thus, craniotomy was performed with DC. On hospitalization day 10, he had orthostatic headache and a JCS score of 1. CT revealed paradoxical midline shift to the opposite side of craniotomy, and syndrome of the trephined was considered. He was placed in the Trendelenburg position until cranioplasty was performed on hospitalization day 18. CONCLUSION: Patients with AEDH presenting severe consciousness issues should undergo hematoma removal. Although DC is controversial, surgeons should administer intensive and prompt treatment according to the circumstance and should consider DC for appropriate AEDH cases. PMID- 29567874 TI - [A Case of Segmental Dysgenesis at the Terminal Portion(C1)of the Internal Carotid Artery with an Anomalous Collateral Vessel Containing Plexiform(Twig like)Networks as a Possible Cause of Intracerebral Hemorrhage]. AB - A 65-year-old woman was transferred to our hospital because of loss of consciousness along with a right hemiplegia due to an intracerebral hematoma(ICH)that extended from the left temporal lobe to the lateral part of the basal ganglia. CT angiograms(CTA)and 3D-rotational angiograms showed an absence of the distal C1 segment of the left internal carotid artery(ICA), and an anomalous collateral vessel arising from the proximal end of the left A2 with plexiform(twig-like)arterial networks, supplying antegrade blood flow to the left middle cerebral artery territory. The caliber of the left carotid arterial system decreased from the origin to the terminal end. The source images of CTA revealed that the plexiform arteries were very close to the ICH, suggesting that the vessels might have caused the bleeding. Because a hypoplastic left carotid canal was observed, the segmental dysgenesis of the C1 portion of the left ICA seemed to have occurred during the early embryonic period. T2-weighted DRIVE images of MRI demonstrated the presence of a cord-like rudimentary structure corresponding to the distal C1 and proximal M1 portions. The patient was managed conservatively and was transferred to another hospital for subsequent rehabilitation. Segmental dysgenesis of the C1 portion is extremely rare. To our knowledge, only a single report has been published. The present findings suggest that 1)an anomalous collateral vessel corresponding to Heubner's artery evolved with residual primitive plexiform(twig-like)arterial networks and 2)this anomalous structure has not been proposed as a type of collateral systems for ICA dysgenesis.

PMID- 29567877 TI - A practical diagnostic approach to hepatic masses. AB - The differential diagnosis of hepatic mass lesions is broad and arriving at the right diagnosis can be challenging, especially on needle biopsies. The differential diagnosis of liver tumors in children is different from adults and is beyond the scope of this review. In adults, the approach varies depending on the age, gender, and presence of background liver disease. The lesions can be divided broadly into primary and metastatic (secondary), and the primary lesions can be further divided into those of hepatocellular origin and nonhepatocellular origin. The first category consists of benign and malignant lesions arising from hepatocytes, while the second category includes biliary, mesenchymal, hematopoietic, and vascular tumors. Discussion of nonepithelial neoplasms is beyond the scope of this review. The hepatocytic lesions comprise dysplastic nodules, focal nodular hyperplasia, hepatic adenoma, and hepatocellular carcinoma, and the differential diagnosis can be challenging requiring clinicopathological correlation and application of immunohistochemical (IHC) markers. Liver is a common site for metastasis, sometimes presenting with an unknown primary site, and proper workup is the key to arriving at the correct diagnosis. The correct diagnosis in this setting requires a systematic approach with attention to histologic features, imaging findings, clinical presentation, and judicious use of IHC markers. The list of antibodies that can be used for this purpose keeps on growing continually. It is important for pathologists to be up to date with the sensitivity and specificity of these markers and their diagnostic role and clinical implications. The purpose of this review is to outline the differential diagnosis of hepatic masses in adults and discuss an algorithmic approach to make a right diagnosis. PMID- 29567878 TI - Evaluation of the osteopontin in oral peripheral and central giant cell granuloma. AB - Aim: Peripheral giant cell granuloma (PGCG) and central giant cell granuloma (CGCG) of the jaws are benign proliferations of spindle-shaped mesenchymal cells and multinucleated giant cells. Despite the histopathologic similarities, they have markedly different clinical behavior. PGCG shows low recurrence rate whereas CGCG shows a variable clinical behavior ranging from nonaggressive lesions to aggressive lesions characterizing by pain, rapid growth, and high recurrence rate. Therefore, the aim of the study was to compare CGCG with PGCG by immunohistochemistry using Ki-67, osteopontin (OPN), and integrin alphavantibodies. Subjects and Methods: Twenty PGCG and 20 CGCG were selected for immunohistochemical evaluation of OPN, integrin alphav, and Ki-67 in multinucleated giant cells and mononucleated cells of PGCG and CGCG. Results: PGCG showed higher Ki-67 immunoreactivity in mononucleated cells compared to CGCG (P < 0.05). There was no reactivity with Ki-67 in multinucleated giant cells of both groups. Mononucleated cells in CGCGs demonstrated increased OPN and integrin alphavexpressions in comparison with PGCGs (P < 0.05). Conclusions: The clinic behavior of CGCG being more aggressive than PGCG might be explained by the high expression of OPN and integrin alphav. Further studies are necessary to evaluate the other OPN receptors and their role on the biologic behavior of these lesions. PMID- 29567879 TI - Role of calcium-sensing receptor, Galectin-3, Cyclin D1, and Ki-67 immunohistochemistry to favor in the diagnosis of parathyroid carcinoma. AB - Background: As histopathological findings of parathyroid carcinoma are not certain, the diagnosis of tumors with degenerative changes may be difficult. In these cases, immunohistochemical markers are beneficial. We aimed to research the acceptability of calcium-sensing receptor (CaSR), Galactin-3, Cyclin D1, and Ki 67 as helpful markers in parathyroid tumors in cases which are difficult to diagnose. Materials and Methods: Those cases who had been diagnosed with atypical parathyroid adenoma and parathyroid carcinoma between 2010 and 2015 were reevaluated. Immunohistochemical markers were applied to this cases. Results: About 21 cases were parathyroid adenoma, 14 were atypical adenoma, and 10 cases were parathyroid carcinoma. According to the immunohistochemical results, global loss of CaSR staining was seen in 50% (5/10) of the patients with carcinoma while there was no loss of staining in those with parathyroid adenoma (P = 0,001). Global loss of CaSR staining was found in only one out of 14 cases with atypical adenoma. The expression of Galactin-3 was found to be positive in 40% (4/10) of carcinoma cases, 71.4% (10/14) of those with atypical adenoma, and 14.3% (3/21) of those with adenoma (P = 0,002). Cyclin D1 expression was determined to be positive in 70% (7/10) of patients with carcinoma, 71.4% (10/14) of atypical adenoma cases, and 23.8% (5/21) of those with adenoma. The Ki-67 proliferation index was seen to be above 5% in 50% (5/10) of carcinoma cases and 35,7% (5/14) of those with atypical adenoma. Conclusion: In these studies, it has been emphasized that the global loss of CaSR staining was used as a negative marker in the diagnosis of carcinoma. In this study, we have also confirmed that the global loss of CaSR staining is a useful marker to determine potential increased malignancy. PMID- 29567880 TI - Myeloid cell leukemia-1 protein expression and myeloid cell leukemia-1 gene amplification in non small cell lung cancer. AB - Background: Myeloid cell leukemia-1 (Mcl-1) is a member of the B-cell lymphoma 2 family known to play a significant role in the regulation of apoptosis. Mcl-1 expression has been studied in nonsmall cell lung cancer (NSCLC) cell lines but has not been previously evaluated as a prognostic factor in clinical samples. Materials and Methods: Formalin-fixed, paraffin-embedded sections from 119 NSCLC, including 33 squamous cell carcinomas (SCC), 55 adenocarcinomas (AC), and 31 either pure adenocarcinoma in situ (AIS) or AC with lepidic features were immunostained by an automated method with rabbit polyclonal Mcl-1. Cytoplasmic Mcl-1 (cMcl-1) immunoreactivity was scored based on intensity and percentage of positive tumor cells in both tumor and adjacent benign epithelium in each case. MCL1 amplification was determined by hybrid capture-based comprehensive genomic profiling (CGP) on a separate cohort of 9393 NSCLC samples. Results: Intense diffuse cMcl-1 overexpression was noted in 35/119 (29%) tumors overall and correlated with tumor type (52% AIS vs. 31% AC vs. 6% SCC, P < 0.0001), tumor grade (48% grade 1 vs. 14% grade 2 vs. 31% grade 3, P = 0.007), small tumor size (36% <=3.0 cm vs. 16% >3.0 cm, P = 0.016), and lengthened survival within the AIS subgroup (100% alive vs. 42% expired, P = 0.018) while showing a trend toward correlation with nonrecurrent disease overall (32% nonrecurrent vs. 11% recurrent, P = 0.072) and within the AC subgroup (33% nonrecurrent vs. 0% recurrent, P = 0.092). MCL1 amplification was identified in 569 (6%) of 9393 NSCLC by CGP. Conclusions: cMcl-1 overexpression appears to occur independently from MCL1 gene amplification in NSCLC and correlates with AIS histologic type, lower tumor grade, smaller tumor size, nonrecurrent disease, and increased survival. PMID- 29567881 TI - Expression of breast cancer type 1 and its relation with expression of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2/neu in breast carcinoma on trucut biopsy specimens. AB - Objective: (1) The objective is to study the immunohistochemical expression of Breast cancer type 1 (BRCA1) in breast carcinoma on trucut biopsy specimens and (2) To relate its expression with that of estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptor 2 (HER-2)/neu and the clinicopathological parameters. Settings and Design: A cross-sectional hospital based study was performed in Lady Hardinge Medical College and Shrimati Sucheta Kriplani Hospital, New Delhi, with collaboration of the Departments of Pathology and Surgery from the period of November 2008 to March 2010. Materials and Methods: The study group included 54 cytologically proven cases of breast carcinoma. The immunohistochemical expression of BRCA1 was studied and related with expression of ER, PR, and HER-2/neu on their trucut biopsies. Results: The altered expression of BRCA1 (i.e., reduced or absent expression) was seen in 44.4% cases of breast carcinoma while 55.6% had positive expression. About 83% of breast carcinomas with altered BRCA1 expression were larger than 3 cm in size. The breast carcinomas showing altered expression were found to be mostly high grade (63.6%). This was statistically significant. The ER and PR negativity were seen in 62.5% and 79.2% breast carcinomas with altered BRCA1 expression, respectively. The score 3 positivity of HER-2/neu was more common among carcinomas with altered BRCA1 expression (21% vs. 16.7%). The triple negativity was found in 41.7% breast carcinomas having altered BRCA1 expression. This was statistically significant. Conclusion: The combination of immunohistochemical expression of BRCA1, ER, PR, and HER-2/neu and clinicopathological details may be helpful in predicting the individuals more likely to carry BRCA1 mutations and thus selecting the candidate and family members for genetic screening for BRCA1 mutations. PMID- 29567882 TI - Immunohistochemical evaluation of lymphovascular invasion in carcinoma breast with CD34 and D2-40 and its correlation with other prognostic markers. AB - Background: Carcinoma breast is ever-evolving and becoming increasingly prevalent in India. Numerous prognostic factors based on morphology and immunohistochemistry (IHC) have been established which need to be interconnected to give patients best possible treatment. Aims: This study aims to confirm and analyze lymphovascular invasion (LVI) detected by hematoxylin and eosin (H and E) using IHC with CD34 and D2-40 and its correlation with other biologic and morphologic prognostic markers. Settings and Design: This was a prospective study. Materials and Methods: Fifty mastectomy specimens diagnosed as infiltrating ductal carcinoma breast on histopathology selected for the study. Evaluation of formalin-fixed paraffin-embedded sections was done using H and E and IHC for estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 HER2/neu receptors, CD34, and D2-40 endothelial markers. Correlation of LVI done with prognostic markers of Carcinoma Breast, namely, age of the patient, tumor size, Nottingham grade, lymph node ratio (LNR), Nottingham prognostic index (NPI), ER/PR status, and HER2/neu status. CD34 and D2-40 utilized to distinguish blood vessel, lymph vessel, and retraction artifacts and to calculate lymphatic microvessel density (LMVD) and blood microvessel density (BMVD). Statistical Analysis Used: SPSS Software Package. Results: LVI was associated with younger age (P = 0.001), greater tumor size (P = 0.007), higher Nottingham grade (P = 0.001), higher LNR (P = 0.001), higher NPI (P = 0.001), Negative ER Status (P = 0.001), Negative PR Status (P = 0.002), Positive HER2/neu status (P = 0.021), Higher Intratumoral BMVD (P = 0.016), Peritumoral BMVD (P = 0.001), and Intratumoral LMVD (P = 0.009). Blood vessels more commonly invaded than lymph vessels. Retraction artifacts can be mistaken for LVI without IHC. Conclusions: D2-40 is a promising marker for lymphatic endothelium. LVI is a poor prognostic marker hence should be evaluated imperatively in all cases of carcinoma breast. PMID- 29567883 TI - Liquid-based cytology versus conventional cytology in fine-needle aspirates of salivary gland neoplasms. AB - Background: Liquid-based cytology (LBC) is a method of retrieving and processing of cytological material for the assessment of both gynecological and nongynecological cases introduced in 1996. Mostly conventional smears (CS) are prepared in Indian scenario; however, due to increasing popularity of LBC in nongynecology specimens, LBC is also used in few centers for diagnosing salivary gland neoplasm. Aim: The aim of this study is to compare CS and LBC in fine needle aspiration cytology (FNAC) of the salivary gland neoplasms in terms of cytomorphological details, adequacy, ease of interpretation, pitfalls, and diagnostic efficiency. Materials and Methods: We conducted a prospective, observational, comparative study which included 64 salivary gland neoplasms. Both CS and LBC (SurePath) were prepared as per standard protocols and examined. Results and Conclusion: In our study, specificity and positive predictive value of both the techniques (conventional and LBC) were found to be 100%. Sensitivity of both the techniques was found to be similar (66.7%). Negative predictive value and diagnostic accuracy of conventional technique were found to be almost similar to that of LBC technique (97.6% vs. 97.2% and 97.7% vs. 97.4%). In terms of adequacy and cellularity, CSs were better than LBC. Ease of interpretation was better with CSs due to abundant chondromyxoid stroma, an important clue in the diagnosis of pleomorphic adenoma. Nuclear details and background were better in LBC as compared to CS. Hence, we conclude that in salivary gland FNAC, both CS and LBC have similar diagnostic efficiency. however, interpretation of conventional smears is easier than Liquid Based Cytology especially in cases of pleomorphic adenoma. However, some advantages of LBC in respect to conventional cytology, with better-preserved morphology obtained from LBC becomes furthermore obligatory. PMID- 29567884 TI - Utility of CD200 expression and CD20 antibody binding capacity in differentiating chronic lymphocytic leukemia from other chronic lymphoproliferative disorders. AB - Background: Chronic lymphoproliferative disorders (CLPDs) are heterogeneous group of disorders with variable clinical presentations and outcomes. Therefore, accurate classification is crucial for treatment planning. At present, flow cytometry immunophenotyping (FCM-IPT) is a useful tool for diagnosing these diseases. However, overlapping immunophenotypes do exist. Recently, differential expression of CD200 and variation in number of CD20 antibody bound per cell (ABC) in different CLPDs has been reported. Materials and Methods: Seventy-seven CLPD cases were analyzed by FCM-IPT for CD200 expression, and Quantibrite bead was used to calculate CD20 ABC. Results: Variability in CD200 expression can help in the differentiation of chronic lymphocytic leukemia (CLL) and hairy cell leukemia (HCL) from other CLPDs. CD200 was brightly expressed in 100% CLL cases, having homogenous bright (2+) intensity. On the contrary, CD200 was uniformly negative in all Mantle cell lymphoma cases except 1, in which the intensity was dim, and the mean fluorescence intensity was significantly lower than CLL. Furthermore, all HCL cases showed bright expression of CD200, thereby making it useful in differentiation from other CLPD with villous lymphocytes. Evaluation of CD20 ABC showed that it differs among various CLPD and was significantly lowest in CLL and highest in HCL both on peripheral blood and bone marrow samples. Conclusion: Our results support the fact that CD200 can be added to routine CLPD panel as it is useful in subcategorizing them. However, inclusion of CD20 ABC to routine panel does not seem plausible but may be done for difficult diagnostic cases or where anti-CD20 therapy is planned. PMID- 29567885 TI - Applicability of 2008 World Health Organization classification system of hematolymphoid neoplasms: Learning experiences. AB - Background: 2008 World Health Organization (WHO) classification of hematolymphoid neoplasms (HLN) has classified them based on morphology, results of various ancillary techniques, and clinical features.[1] There are no studies looking at the applicability of WHO classification. Aims: The aim of the study was to calculate proportions of all HLN subtypes seen during 1-year period based on 2008 WHO classification of HLN and study applicability and also shortcomings of practices in a tertiary care center in India. Materials and Methods: This was a 1 year retrospective study (January 1st, to December 31st, 2010) where cases were identified using hospital/laboratory electronic records. Old follow-up and referral cases were excluded from the study. Only newly diagnosed cases classified into categories laid down by 2008 WHO classification of HLN included. Results: Out of 2118 newly diagnosed classifiable cases, 1602 (75.6%) cases were of lymphoid neoplasms, 489 (23.1%) cases of myeloid neoplasms, 16 (0.8%) cases of histiocytic and dendritic cell neoplasms, and 11 (0.5%) cases of acute leukemias of ambiguous lineage. Overall, most common HLN subtype was diffuse large B-cell lymphoma (n = 361, 17.0%). Precursor B-lymphoblastic leukaemia/lymphoma (n = 177, 48.2%) was the most common subtype within pediatric age group. Conclusions: All major subtypes of HLN were seen at our center and showed trends almost similar to those seen in other Indian studies. Molecular/cytogenetic studies could not be performed on a significant number of cases owing to logistic reasons (unavailability of complete panels and also cost-related issues) and such cases could not be classified as per the WHO classification system. PMID- 29567886 TI - CagA and VacA genes of Helicobacter pylori and their clinical relevance. AB - Context: : Helicobacter pylori is associated with the development of a variety of gastroduodenal diseases which varies with ethnicity and the type of strains that infect the population. Aims: This study aims to evaluate the prevalence of H. pylori cagA and vacA genotypes in our region and to determine their relationship to the severity of the lesions that they cause. Settings and Design: : This study was an observational cross-sectional study. Subjects and Methods: DNA was extracted from 165 gastric biopsies from patients evaluated for dyspepsia. PCR was used to detect cagA and vacA (s1, s2, m1, m2) genes of H. pylori. Statistical analysis of associations was performed between endoscopy findings and virulence genes. Statistical Analysis Used: Pearson Chi-square test and Fischer's exact test. Results: The prevalence of H. pylori infection was 37% and the dominant genotypes was vacA s1 cagA-positive strain (54.1%) in this study. The vacAs1 subtype was found in all patients with peptic ulcer disease (PUD). The entire normal study group had VacA s2 variant only. This clearly shows that vacA s1 is a significant virulence marker and patients harboring s1 strains are more prone to develop ulcers (P = 0.007). There was a significant association of cagA with s1 strain rather than s2. Variation in VacA m genotype did not seem to have any association with disease status. There was a statistically significant association between the presence of cagA gene and PUD rather than the nonulcer dyspepsia (P = 0.027). Conclusion: The predominant genotype in our population was cagA positive vacA s1, which was found to be significantly associated with patients with gastric diseases, especially PUD. VacA s1 can serve as a single best virulence marker of the disease manifestation. PMID- 29567887 TI - Role of nm23H1 in predicting metastases in prostatic carcinoma. AB - Background: Non-metastatic nm23H1 gene is thought to play a critical role in cell proliferation. Studies of nm23H1 have been done in many other malignancies. But none of these studies took up nm23H1 gene as predictor in the metastases of prostatic carcinoma. Aims and Objectives: To study the expression of nm23H1 in prostatic lesion and to correlate nm23H1 expression with presence of metastases, tumour stage, tumour grade and with PSA level serum. Setting and Design: Tertiary hospital based retrospective and prospective study done in a period of one year from thirty patients having prostatic lesion confirmed by biopsy. Material and Methods: Immunohistochemistry for nm23H1 was performed on unstained coated sections of prostatic lesions to study the relation with prostatic lesion and their correlation with age, PSA level, tumour stage, grading. Clinical data was collected from medical records. Statistical Analysis: SPSS Version 15 analysis software was used. The value were presented in number(%) and Mean +/- SD. Results: Majority of patients belong to age group 61 to 70yrs.Gleason score >7 were seen in 55% of patients of adenocarcinoma with and without metastasis. The difference in PSA levels between BPH and adenocarcinoma was significant (P < 0.001). IHC expression for nm23H1 gene showed positive findings in all the cases (P = 1). PSA values >20ng/ml showed maximum % mean expression (98.64%) as compared to PSA levels <10 ng/ml (96.91%). Conclusion: IHC expression of nm23H1 is not an effective tool to distinguish among the cases of BPH, adenocarcinoma of prostate with and without metastasis. Hence nm23H1 gene does not behave like an antimetastatic gene in prostatic lesions. PMID- 29567888 TI - Prevalence of scrub typhus in pyrexia of unknown origin and assessment of interleukin-8, tumor necrosis factor-alpha, and interferon-gamma levels in scrub typhus-positive patients. AB - Background: Scrub typhus is lesser known cause of fever of unknown origin in India. Even if there have been reports documenting the prevalence of scrub typhus in different parts of India, it is still an unknown entity, and clinicians usually do not consider it as differential diagnosis. The present study was performed to document the prevalence of scrub typhus among febrile patients in western part of Uttar Pradesh and to assess the clinical profile of infected patients on the one hand and knowledge, attitude, and practices among clinicians on the other. Materials and Methods: A total of 357 adult patients with fever of more than 5-day duration were recruited. All patients underwent complete physical examination, and detailed clinical history was elicited as per predesigned pro forma. After primary screening to rule out malaria, enteric fever, and leptospirosis infection, secondary screening for scrub typhus was done by rapid screen test and IgM ELISA. Results: Scrub typhus infection was positive in 91 (25.5%) cases. The most common symptoms among the patients were fever (100%), pain in abdomen (79.1%), pedal edema 56 (61.5%), rash 44 (48.3%), headache 44 (48.3%), vomiting 42 (46.1%), constipation 33 (36.2%), cough 28 (30.7%), and lymphadenopathy 20 (21.9%). The median values of interleukin-8, interferon-gamma, and tumor necrosis factor-alpha in healthy controls were 15.54 pg/ml, 7.77 pg/ml, and 54.1 pg/ml, respectively, while the median values of these cytokines in scrub typhus-positive patients were 21.04 pg/ml, 8.74 pg/ml, and 73.8 pg/ml, respectively. Conclusion: Our results highlight that scrub typhus infection is an important cause of pyrexia of unknown origin, and active surveillance is necessary to assess the exact magnitude and distribution of the disease. PMID- 29567889 TI - Evaluation of procalcitonin as a diagnostic marker in neonatal sepsis. AB - Context: Neonatal sepsis is an early infection occurring within 28 days of the postnatal life. It has nonspecific signs and symptoms which make the diagnosis cumbersome. It inflicts an increase in morbidity and mortality among neonates. Procalcitonin (PCT) is yet another acute phase reactant, which is synthesized by the C-cells of thyroid gland. Aims: The aim of our study is to evaluate PCT as a diagnostic marker of neonatal sepsis in comparison with C-reactive protein (CRP). Subjects and Methods: A prospective cross-sectional study was conducted at our tertiary care hospital in Puducherry. The study was conducted over a period of 5 months from November 2015 to 2016. The study included all neonates with clinical signs of sepsis. The neonates were assigned into three groups as proven sepsis, suspected sepsis, and no sepsis group. The CRP level and PCT level were compared between the three groups, and their sensitivity and specificity were calculated. Statistical Analysis Used: The mean, standard deviation, and standard error of mean were calculated. The groups were compared using one-way ANOVA. The diagnostic test efficiency was evaluated by receiver operating characteristic curve analysis. Results: A total of 75 neonates were included in our study. There were 9 (12%) neonates with proven clinical sepsis, 47 (62.6%) neonates with suspected clinical sepsis, and 19 (25.3%) neonates with no sepsis. The mean and standard error of mean were calculated for CRP and PCT in all the three groups. The results showed a sensitivity of 88.90% for both CRP and PCT and specificity of 89.40% for CRP and 80.30% for PCT. The common organisms isolated from culture positive group were Escherichia coli (22.2%), Pseudomonas aeruginosa (22.2%), and Candida albicans (22.2%), followed by Klebsiella pneumoniae, Acinetobacter baumannii, and methicillin-resistant Staphylococcus aureus. Conclusions: PCT may not be sufficiently used as a sole marker of sepsis in neonates compared to CRP. PCT in conjunction with CRP and other tests for septic screen can aid in better diagnosis of neonatal sepsis.

In our case, clinicoradiological correlation, bronchoscopy, and computed tomography-guided biopsy revealed the diagnosis of primary pulmonary non-Hodgkin's lymphoma (PPNHL) on histopathology and immunohistochemistry. We discuss the approach to hilar masses. PPNHL is a rare malignant lymphoma most common being mucosa-associated lymphoid tissue lymphoma. Various therapeutic options are available. The chemotherapy regimen consisting of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) is preferred. PMID- 29567891 TI - Utility of MOC-31 monoclonal antibody in differentiating metastatic adenocarcinoma cells and reactive mesothelial cells in effusion cytology. AB - In effusion cytology, a clear distinction between reactive mesothelial cells and metastatic adenocarcinoma cells is sometimes challenging mainly due to similarities in the cytomorphological features. In such cases for definitive diagnosis, paraffin-embedded cell block examination and immunohistochemistry are helpful in making this distinction. MOC-31 is one of the proposed immunomarker for adenocarcinoma cells. We undertook to evaluate the role of MOC-31 as a marker for identifying adenocarcinoma cells in effusion specimen. A total of 185 paraffin-embedded cell blocks of effusion samples were identified, of these 111 cases were of metastatic adenocarcinoma. MOC-31 was positive in 101 of the 111 cases of metastatic adenocarcinoma. Minimal focal cytoplasmic staining was also seen in 7 of the 74 cases of reactive mesothelial cells, but these were taken negative as they did not show membrane positivity. The sensitivity and specificity of MOC-31 for metastatic adenocarcinoma cells were 92.5%, and 100% respectively, positive and negative predictive value (NPV) was 100% and 91.14%, respectively. MOC-31 can be used as a reliable marker in effusions for distinguishing metastatic adenocarcinoma from reactive mesothelial cases.

AB - Lymphangioleiomyomatosis (LAM) is a rare, genetically determined, progressive interstitial lung disease, which almost exclusively affects women, especially at the childbearing age. The initial symptoms and radiographic changes in a patient with LAM are always associated with the respiratory system. Here, we present a case of mediastinal and abdominal LAM of a 22-year-old male, where LAM cells are negative for human melanoma black-45 ( HMB-45). The report of this uncharacterized LAM case will make a significant contribution to the realization of LAM associated clinical features, diagnostic approaches, and its afterward treatments. PMID- 29567893 TI - Coats' disease - disease of the eye rarely encountered by pathologists. AB - Coats' Disease is an idiopathic condition of the eye affecting young children although it can be seen in adults. Most patients present early in life with unilateral decreased vision, strabismus or leukocoria. The most important differential diagnosis is unilateral retinoblastoma. In this study we report a case of coat's disease in an young girl, and evaluate histopathological and clinical findings. PMID- 29567894 TI - Merkel cell carcinoma with seborrheic keratosis: A unique association. AB - Merkel cell carcinoma (MCC) is a rare, clinically aggressive neuroendocrine carcinoma of the skin; MCC is 40 times less common as compared to melanoma. The most frequently reported sites have been the head and neck, extremities, and trunk. Potential mimics include malignant melanoma, lymphoma, or metastatic small cell (neuroendocrine) carcinomas. Histopathology of MCC resembles small cell carcinoma both morphologically and on IHC. The possible cell of origin was proposed as the Merkel cell, which functions as a mechanoreceptor. It has a high chance of local recurrence, regional and distant spread. In recent times, Merkel cell polyomavirus has been implicated as the causative agent for this tumor. The same agent has a reported etiologic association with other skin lesions, including seborrheic keratosis. PMID- 29567895 TI - Invasive cutaneous mucormycosis in a preterm neonate presenting as a vesicobullous lesion. AB - Mucormycosis is a relatively rare fungal infection seen in immunocompromised patients. Very few cases of invasive cutaneous mucormycosis occurring in neonates have been reported in literature. It is an aggressive disease with a mortality rate of around 64% in neonates, so a high index of suspicion is essential for rapid diagnosis and definitive treatment with broad-spectrum antifungals such as Amphotericin B. We present a case of a premature infant born at 25 weeks of gestation who developed vesicobullous lesions all over the body on day 5 of life. Biopsy from the vesicles confirmed the presence of angioinvasive fungal hyphae of mucormycosis which were highlighted on Periodic acid-Schiff and Grocott stain. PMID- 29567896 TI - Syringocystadenoma papilliferum and trichoblastoma arising in the nevus sebaceous. AB - Nevus sebaceous (NS) is a clinically common benign tumor and has a high potential to develop into a great diversity of neoplasms of epidermal and adnexal origins. However, it is a rare phenomenon of the coexistence in a single NS with two or more skin tumors. We report a case of a 58-year-old woman with two kinds of neoplastic proliferation including syringocystadenoma papilliferum and trichoblastoma arising in NS on the scalp. PMID- 29567897 TI - Strongyloides stercoralis hyperinfection in an unconscious diabetic patient with dermatomyositis. AB - A case of Strongyloides stercoralis hyperinfection in a patient with dermatomyositis and diabetes mellitus is herein reported. The case was a 60-year old female admitted due to watery diarrhea and unconsciousness. She had a 10-year history of chronic immunosuppressive therapy including methotrexate and prednisolone for dermatomyositis. Stool parasitological examination revealed numerous rhabditiform larvae of threadworm "S. stercoralis." Larva in stool sample was characterized by sequencing of mitochondrial DNA. After treatment with ivermectin, the patient recovered without evidence of S. stercoralis in follow-up stool samples. In endemic areas, stool examination for detection of S. stercoralis should be performed on a regular basis for all patients receiving immunosuppressive therapy, as early detection and treatment are necessary to minimize complications of severe strongyloidiasis. PMID- 29567898 TI - Kikuchi's disease (histiocytic necrotizing lymphadenitis): A rare presentation with acute kidney injury, peripheral neuropathy, and aseptic meningitis with cutaneous involvement. AB - Kikuchi's disease (KD) also known as histiocytic necrotizing lymphadenitis is rare, idiopathic, generally self-limited cause of lymphadenitis. We present a case of twenty year young female who presented in critically ill state with fever, cervical and axillary lymphadenopathy, rash, vomiting and altered sensorium and found to have neurological, hepatic, renal and dermatological involvement. Kikuchi's disease should be considered in differential diagnosis of fever and lymphadenopathy and though benign can sometimes present with multi organ involvement. It is because of rarity of this disease with unusual complications, present case is reported. PMID- 29567899 TI - Autopsy findings in an atypical case of occult massive fatal pulmonary embolism in a backdrop of hyperhomocysteinemia. AB - A 43-year-old apparently healthy male presented with fever and presyncope. He was suspected to have massive pulmonary thromboembolism based on the clinico biochemical profile. Despite aggressive thrombolytic therapy, he succumbed to his illness within 12 h of admission. Postmortem examination showed massive pulmonary thromboembolism and hyperhomocysteinemia with low high-density lipoproteins (HDL) cholesterol with antemortem blood sample. Herein, we report autopsy findings in a rare case of a young male with occult massive pulmonary thromboembolism without deep vein thrombosis, who had an atypical clinical presentation and was found to have underlying hyperhomocysteinemia and decreased HDLc. An acute, massive PE can present a diagnostic challenge due to the rate and severity of decompensation seen in afflicted patients. A high index of suspicion is required for early detection of pulmonary embolism in a young patient with atypical presentation and without obvious risk factors. PMID- 29567900 TI - Anastomosing hemangioma with extensive fatty stroma in the retroperitoneum. AB - Anastomosing hemangiomas are a recently recognized benign vascular neoplasm, first described by Montgomery and Epstein in 2009. A few cases have been described in the genitourinary tract, especially in the renal hilum. These are fairly well-demarcated lesions with lobules of sinusoidal-like capillaries lined by hobnail endothelial cells containing eosinophilic hyaline globules in the cytoplasm. Extramedullary hematopoiesis has been described in a few cases, along with large feeding vessels. A predominant adipocytic component has been described in only one case.[9] We describe a case of a retroperitoneal anastomosing hemangioma occurring in an extrarenal site in a 53-year-old female, followed by a review of the current literature. PMID- 29567901 TI - Mixed epithelial and stromal tumor - A solid-cystic renal neoplasm undergoing malignant transformation: A rare case report. AB - We present a case of 53-year-old female who came with the complaints of mass on the right side of the abdomen noticed 3 weeks back. There was no history of localized swelling or rise of temperature, no history of weight loss, or evening rise of temperature. On examination, there was a flank mass which was bimanually palpable and tender. Routine laboratory investigations were within normal limits, except for the presence of hematuria in routine urinalysis. Computed tomography scan abdomen revealed a large multiloculated solid-cystic mass lesion with septation in the right-sided kidney. Cystic renal cell carcinoma was suspected and conventional open right radical nephrectomy was done. Grossly, the tumor was solid-cystic containing blood-tinged fluid. Microscopy revealed a complex tumor with both epithelial and stromal proliferation and with the aid of immunohistochemistry a diagnosis of mixed epithelial and stromal tumor undergoing malignant transformation was concluded. PMID- 29567902 TI - A rare case of primary female urethral adenocarcinoma: Columnar type with colonic adenocarcinoma features. AB - Female urethral carcinoma is extremely rare and accounts for 0.02% of all women's cancers and <1% of cancers in the female genitourinary tract. Adenocarcinoma accounts for only 10% of urethral carcinomas in females. Due to their location, presentation is usually late and tumors are often missed on physical examination. As in this case, nonspecific symptoms in the early stages may delay the diagnosis in most patients. Herein, we present an extremely rare case of the columnar type of primary female urethral adenocarcinoma exhibiting colonic adenocarcinoma features which to the authors' best knowledge has not been reported to date. The present study emphasizes the importance of a careful clinical examination and also highlights the role of imaging studies, and biopsy in making an accurate preoperative diagnosis of this rare disease. The disease may have devastating sequelae due to local and metastatic involvement if not recognized and treated earlier. PMID- 29567903 TI - Uterine tumor resembling ovarian sex cord tumor: Histomorphological features.

A critical evaluation of histological features is essential for diagnosis and management of these cases. PMID- 29567904 TI - Primary rhabdomyosarcoma in ovary - Pathologist clinches it all. AB - Sarcomas are extremely complex and heterogeneous group of malignancies. However, exact categorization of the type of sarcoma is essential for the individualized approach for a given patient. It is mandatory that sarcomas should be treated in tertiary care centers with good pathology support and expertise. Here, we present an apt example of a young girl with large abdominal mass which was diagnosed as ovarian rhabdomyosarcoma (RMS). Besides, her excellent response to RMS regimen further reinforces the findings. PMID- 29567905 TI - Diminished CD40L expression on T-cells in a case of disseminated cryptococcosis. AB - X-linked hyperimmunoglobulin M (HIGM) syndrome may increase the susceptibility of patients to disseminated cryptococcal infections primarily due to CD40L deficiency that causes defective cross talk between T- and B-cells, thus preventing class switching. In HIGM syndrome, serum IgM levels are elevated with severe reduction in serum immunoglobulin G (IgG) and IgA levels. In addition, the expression of CD40L (CD154) on in vitro-activated T-cells is severely reduced or absent. Here, we describe a rare, and perhaps, the first reported case in India of a 3-year-old male child with X-linked HIGM immunodeficiency syndrome who developed disseminated Cryptococcosis. Evaluation of the serum IgG profile of the patient revealed increased serum IgM levels with reduced IgG and IgA levels. Both the frequency and the function of T-cells, primarily CD40L on activated T-cells, showed weak expression suggestive of HIGM syndrome.

AB - Aim: To determine whether dental treatment under general anesthesia (GA) would improve quality of life for children as reported by Saudi Arabian parents using a Parental-Caregivers Perceptions Questionnaire (P-CPQ) and a Family Impact Scale (FIS). Methods: Sixty-six parents completed P-CPQ and FIS scales four to eight weeks after their children (ages three to ten years) underwent comprehensive dental treatment under GA. Postoperative data were compared with baseline data gathered before GA using paired t-test at the 0.05 level of significance. The responsiveness of the P-CPQ and the FIS and the magnitude of changes in children's quality of life as a result of dental treatment were determined by calculating the effect size (ES). Cross-sectional construct validity and internal consistency were also examined using the pretreatment scores of the P-CPQ and the FIS scores. Results: The overall P-CPQ and FIS scores showed a significant decrease following treatment, concomitant with large ES in both scales and all their subscales with the exception of social wellbeing, which showed moderate ES (ES 0.59). The greatest relative changes were seen in the oral symptoms (ES 1.81) and the family activity (ES 1.57) subscales. Conclusion: Dental treatment under GA is associated with considerable improvement in children's quality of life as perceived by Saudi parents. The P-CPQ and the FIS scales are valid and responsive to changes resulting from dental treatment of young children affected by severe childhood caries. PMID- 29567922 TI - Six-Year Survival and Early Failure Rate of 2918 Implants with Hydrophobic and Hydrophilic Enossal Surfaces. AB - The aim of this chart review was to obtain an objective, quantitative assessment of the clinical performance of an implant line used in an implantological office setting. Implants with hydrophilic (INICELL) and hydrophobic (TST; both: Thommen Medical AG, Grenchen, Switzerland) enossal surfaces were compared and the cumulative implant survival rate was calculated. The data of 1063 patients that received 2918 implants (1337 INICELL, 1581 TST) was included. The average follow up time was 2.1 (1.1-5.4) years for INICELL and 4.5 (1.3-5.9) years for TST implants (Thommen Medical AG, Switzerland). In the reported period 7 implants with INICELL (0.5%) and 23 TST implants (1.5%) failed. This difference was statistically significant. The analysis of cases treated and followed up in a single implantological office for 6 years confirmed the very good clinical outcome that was achieved with both used implant lines. Within the limitations of this retrospective analysis, the overall early failure rate of the hydrophilic implants was significantly lower than that of hydrophobic implants. The use of hydrophilic implants allows the clinician to obtain less early failures, hence the interest of an up-to-date surface for the daily work of an implant practice. PMID- 29567923 TI - The Peri-Implant and Periodontal Microbiota in Patients with and without Clinical Signs of Inflammation. AB - Late implant failures, caused by the inflammation of surrounding tissues are a problem in implant dentistry. The path of bacterial transmission from teeth to implants is not completely understood. Therefore, the purpose of this study was to analyze intraindividual bacterial transmission characterizing subgingival microbiomes in teeth and implants, both in healthy subjects and in those with signs of periodontitis or peri-implantitis. Samples of peri-implant and dental sulcus fluid were collected. To identify the predominant microbiota, amplified fragments of bacterial 16S rRNA gene were separated by single strand conformation polymorphism analysis, sequenced and taxonomically classified. A total of 25 different predominant genera were found in the diseased group and 14 genera in the healthy group. Species richness did not differ significantly between implants, neighboring teeth and teeth with largest probing depth in the diseased group. Additionally, no differences between teeth and implants in the healthy group were detected. In contrast, microbial diversity varied between the different sampling points. Species richness is similar in healthy and diseased sites, but the composition of the bacterial community differed within the individual subjects. The underlying analyses strongly suggest that complete transmission from neighboring teeth to implants is unlikely. PMID- 29567924 TI - Effect of Long-Term Consumption of Lactobacillus paracasei SD1 on Reducing Mutans streptococci and Caries Risk: A Randomized Placebo-Controlled Trial. AB - BACKGROUND: A previous study revealed Lactobacillus paracasei SD1, a probiotic strain, could reduce mutans streptococci (MS). The aim of this study was to evaluate the long-term effects of L. paracasei SD1 on the colonization of MS, and whether caries lesions developed. METHODS: After informed consent, 122 children were recruited and randomly assigned to the probiotic or control groups. The probiotic group received milk-powder containing L. paracasei SD1 and the control group received standard milk-powder once daily for six months. Salivary MS and lactobacilli were enumerated using differential culture at baseline and at three month intervals for 12 months. The persistence of L. paracasei SD1 was investigated using AP-PCR for DNA-fingerprinting. Oral health was examined at baseline and at the end of the study according to WHO criteria. RESULTS: The long term consumption could prolong colonization of L. paracasei SD1. Significantly reduced MS counts and increased lactobacilli levels were found among children in the probiotic group. There were less caries lesions in the probiotic group at the end of the study. A significant reduction of the development of new caries lesions (4.5 times) was observed in the high caries risk group but not in the low caries risk group. CONCLUSIONS: Results demonstrate that the long-term daily ingestion of the human-derived probiotic L. paracasei SD1 significantly reduces the number of MS and caries risk in the high caries group. PMID- 29567925 TI - Randomized Clinical Investigation of Titanium Implants with and without Platform Switching: Six Months' Radiographic and Clinical Outcome. AB - The aim of this study was to obtain a randomized, clinical and radiological comparison of implants with and without platform switching (PFS). The two compared titanium implant types differed only in the microgap position: test (PFS) or control (StE, no PFS). All implants were inserted in posterior regions and followed up for six months after abutment connection (AC). Twenty one patients with 21 PFS and 18 StE implants completed the six-month evaluation. No implant failed. One complication (exposed cap screw) was reported at AC. No statistically significant difference was observed between the marginal bone level of PFS and StE implants. Their bone level stabilized approximately 1 mm below the microgap. Based on the outcome of this short-term study with a limited number of patients, it seems unlikely that the optimal clinical and radiological outcome obtained with the tested standard implant (no PFS) can be improved by introducing an inward microgap shift (PFS). PMID- 29567926 TI - Arrested Pneumatization of the Sphenoid Sinus on Large Field-of-View Cone Beam Computed Tomography Studies. AB - Arrested pneumatization of the sphenoid sinus is a normal anatomical variant. The aim of this report is to define cone beam computed tomography (CBCT) characteristics of arrested pneumatization of sphenoid sinus in an effort to help differentiate it from invasive or lytic skull base lesions. Two cases are presented with incidental findings. Both studies, acquired for other diagnostic purposes, demonstrated unique osseous patterns that were eventually deemed to be anatomic variations in the absence of clinical signs and symptoms although the pattern of bone loss and remodeling was diagnosed as pneumatization of the sphenoid sinus by a panel of medical and maxillofacial radiologists following contrasted advanced imaging. It is important to differentiate arrested pneumatization of the sphenoid sinus from lesions, such as arachnoid granulations, acoustic neuroma, glioma, metastatic lesions, meningioma, or chordoma, to prevent unnecessary biopsies or exploratory surgeries that would consequently reduce treatment costs and alleviate anxiety in patients.

PMID- 29567928 TI - Implant Supported Fixed Dental Prostheses Using a New Monotype Zirconia Implant-A Case Report. AB - Currently, titanium or specific titanium alloys are the most often used materials for the fabrication of dental implants. Many studies have confirmed the osseointegrative capacity and clinical long-term performance of moderately rough titanium implants. However, disadvantages have also been reported with regard to peri-implant infections and the titanium metal properties. Tooth colored ceramic implants have attracted the interest of clinicians since the end of the 1960s. Initially, alumina was used for the fabrication of ceramic implants; however, due to the poor biomechanical properties, alumina implants are not commercially available any more. Since end of the 1990s, zirconia has been established in dentistry due to its superior biomechanical properties compared to other oxide ceramics such as alumina. Currently, zirconia is the material of choice for the fabrication of ceramic implants. Zirconia implants show superior biocompatibility compared to titanium and other metals. Additionally, it has been reported that zirconia implants with a micro-rough surface topography show at least a comparable osseointegrative capacity and similar clinical survival rates to moderately rough titanium implants. The present case reports a fixed implant supported reconstruction of a large edentulous space with compromised local bone conditions using new monotype zirconia dental implants with a micro-rough surface topography. PMID- 29567929 TI - Management of Antithrombotic Agents in Oral Surgery Maria Martinez and Dimitrios A. Tsakiris. AB - Systemic anticoagulation with intravenous or oral anticoagulants and antiplatelet agents is an efficient treatment against thromboembolic or cardiovascular disease. Invasive dental procedures or oral surgery might be associated with bleeding complications if carried out under anticoagulants. Patients on vitamin K antagonists, new direct anticoagulants or antiplatelet agents having dental interventions with low-risk for bleeding do not need interruption of anticoagulation. In case of bleeding complications local hemostatic measures, such as local surgical sutures, fibrin glue, local antifibrinolytic treatment with tranexamic acid, or e-aminocaproic acid suffice to stop bleeding. In patients with high risk of bleeding an individual assessment of the benefit/risk ratio of interrupting anticoagulation should be carried out. Bridging the long term anticoagulation with short-term anticoagulants should be planned according to national or international guidelines. The introduction of the newer direct oral anticoagulants having more flexible pharmacokinetic properties has facilitated bridging, allowing short-term interruption without increasing the risk of relapsing thrombotic or cardiovascular events. PMID- 29567930 TI - A Study of the Management of Patients Taking Novel Oral Antiplatelet or Direct Oral Anticoagulant Medication Undergoing Dental Surgery in a Rural Setting. AB - PURPOSE: Novel oral antiplatelet (NOAP) (prasugrel and ticagrelor) and direct oral anticoagulant drugs (DOAC) (dabigatran, rivaroxaban and apixaban) have emerged in the last decade. This study was undertaken to determine current approaches taken to the management of patients taking these agents in dental practice in a remote and rural setting. METHODS: A small retrospective study was carried out in a small island population that identified patients taking one of the above drugs. All national health service and private dental records were examined to determine the type of treatment carried out and whether drug therapy, treatment plans or actual treatment were modified as a result of NOAP or DOAC therapy. In addition other outcomes such as referral to another service for advice or treatment and any adverse bleeding events were noted. RESULTS: 156 dental encounters for 95 patients taking one of the drugs were identified. Significant events were identified in sixteen encounters and the management of patients taking each drug type differed significantly between cases but no patients returned with troublesome post-operative bleeding. CONCLUSIONS: The approaches taken by dental surgeons in Orkney in the management of the NOAPs and DOACs varied and this is likely to be a reflection of the limited literature available. PMID- 29567931 TI - Mineralization of Early Stage Carious Lesions In Vitro-A Quantitative Approach. AB - Micro computed tomography has been combined with dedicated data analysis for the in vitro quantification of sub-surface enamel lesion mineralization. Two artificial white spot lesions, generated on a human molar crown in vitro, were examined. One lesion was treated with a self-assembling peptide intended to trigger nucleation of hydroxyapatite crystals. We non-destructively determined the local X-ray attenuation within the specimens before and after treatment. The three-dimensional data was rigidly registered. Three interpolation methods, i.e., nearest neighbor, tri-linear, and tri-cubic interpolation were evaluated. The mineralization of the affected regions was quantified via joint histogram analysis, i.e., a voxel-by-voxel comparison of the tomography data before and after mineralization. After ten days incubation, the mean mineralization coefficient reached 35.5% for the peptide-treated specimen compared to 11.5% for the control. This pilot study does not give any evidence for the efficacy of peptide treatment nor allows estimating the necessary number of specimens to achieve significance, but shows a sound methodological approach on the basis of the joint histogram analysis. PMID- 29567932 TI - Oral Candida Carriage and Morphotype Differentiation in Chronic Periodontitis Patients with and without Diabetes in the Indian Sub-Continent. AB - The aim of this study was to assess the oral Candida carriage and morphotype differentiation of Candida species in chronic periodontitis patients, with and without diabetes mellitus. This cross sectional study included 30 subjects in the age range of 40-60 years, who were divided into two groups: 15 chronic periodontitis only (CP) patients, and 15 chronic periodontitis patients with diabetes (CPD). Clinical measurements included plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and fasting blood sugar level (FBS). The unstimulated whole saliva samples were collected for fungal analysis. Candida carriage was analyzed by measuring colony forming units (CFU) following the culture of samples. Qualitative morphotype differentiation of Candida species from yeast to hyphal form was analyzed using Periodic acid-Schiff (PAS) staining. There was no statistically significant difference between CP and CPD groups for the periodontal parameters. However, a significantly higher Candida species CFU count was found in CPD (0.33 +/- 0.23) as compared to CP (0.05 +/- 0.04) group. This pilot study suggests that the occurrence of Candida species is higher in the saliva of chronic periodontitis patients with diabetes as compared to patients with chronic periodontitis alone.

PMID- 29567935 TI - Normothermic Machine Perfusion versus Cold Storage of Liver in Pig Model: A Meta Analysis. AB - BACKGROUND Normothermic machine perfusion (NMP) is a novel strategy used for organ preservation. We aimed to determine the overall efficacy of NMP for liver preservation versus traditional static cold storage (CS). MATERIAL AND METHODS We performed a meta-analysis of the literature to evaluate the efficacy of NMP in experimental pig models of liver preservation. We use the standardized mean difference and 95% confidence intervals (CI) to calculate statistics and used the random effects model for the combined analysis of the results. RESULTS A total of 16 studies from 12 published articles were included. The combined results showed that NMP significantly decreased alanine aminotransferase (ALT), aspartate aminotransferase (AST), and hyaluronic acid levels in serum or perfusate, significantly increased bile production, and had a similar 5-7-days survival rate after liver transplantation compared with the CS group. CONCLUSIONS NMP provides superior graft preservation compared with CS in the pig model. PMID- 29567934 TI - Dentinogenic Specificity in the Preclinical Evaluation of Vital Pulp Treatment Strategies: A Critical Review. AB - Reviews on the clinical performance of vital pulp treatment strategies and capping materials repeatedly showed an insufficient grade of evidence concerning their therapeutic validity. The biological mechanisms underlying the regenerative potential of pulp-dentin complex have attracted much attention during the last two decades, since new pulp treatment modalities have been designed and tested at the preclinical level. It has been recognized that evaluation should be based on the specific ability of therapeutic interventions to signal recruitment and differentiation of odontoblast-like cells forming a matrix in a predentin-like pattern, rather than uncontrolled hard tissue deposition in a scar-like form. The aim of the present article was to critically review data from histological experimental studies on pulp capping, published during the last 7 decades. A comprehensive literature search covering the period from 1949 to 2015 was done using the Medline/Pubmed database. Inclusion of a study was dependent on having sufficient data regarding the type of capping material used and the unit of observation (human permanent tooth in vivo or animal permanent dentition; primary teeth were excluded). The post-operatively deposited matrix was categorized into three types: unspecified, osteotypic, or dentin-like matrix. One hundred fifty two studies were included in the final evaluation. Data from the present systematic review have shown that only 30.2% of the 152 experimental histological pulp capping studies described the heterogenic nature of the hard tissue bridge formation, including osteotypic and tubular mineralized tissue. Structural characteristics of the new matrix and the associated formative cells were not provided by the remaining 106 studies. Analysis showed that more careful preclinical evaluation with emphasis on the evidence regarding the dentinogenic specificity of pulp therapies is required. It seems that selection of appropriate vital pulp treatment strategies and pulp capping materials would be further facilitated in terms of their therapeutic validity if international consensus could be reached on a select number of mandatory criteria for tissue-specific dentinogenic events. PMID- 29567936 TI - Splenic Rupture as the First Manifestation of Babesia Microti Infection: Report of a Case and Review of Literature. AB - BACKGROUND Babesiosis is an emerging, tick-borne zoonosis caused by intraerythrocytic protozoa of the genus Babesia. Babesia microti is the main pathogen causing human disease and is endemic in the northeastern and upper midwestern parts of the USA. Severity of infection ranges from mild, self limited, febrile viral-like illness accompanied by nonspecific symptoms to life threatening infection complicated by severe hemolytic anemia, disseminated intravascular coagulation (DIC), acute respiratory distress syndrome (ARDS), and renal or/and hepatic failure. Splenic rupture (SR) is a very rare but life threatening complication of severe B. microti infection. CASE REPORT A 79-year old female farmer from Wisconsin, USA was admitted during summer with hemorrhagic shock secondary to spontaneous splenic rupture. She was transfused with 3 units of packed red blood cells (PRBC) and underwent emergent splenectomy. Postoperatively, she recovered well and was discharged on postoperative day 4. However, she was re-admitted on postoperative day 10 for febrile hemolytic anemia. Further exposure history was obtained and was significant for multiple tick bites 8 weeks preceding the index hospitalization. She was promptly diagnosed with babesiosis and Lyme disease co-infection. She responded favorably to 10 days of azithromycin and atovaquone and 21 days of oral doxycycline. CONCLUSIONS Despite its rare occurrence, SR due to B. microti infection is a dreaded complication that can rapidly progress to hemorrhagic shock and death. In contrast to other complications of babesiosis, SR is not correlated with parasite burden or immune status of the affected host. Babesiosis should be considered as part of the differential diagnosis in patients from endemic areas presenting with atraumatic splenic rupture.

AB - BACKGROUND Imatinib is actively transported into cells by the organic cation transporter (OCT1), encoded by SLC22A1. As a result, the expression of SLC22A1 is considered a prognostic marker for treatment with imatinib in patients with chronic myeloid leukemia (CML). Although limited, there is conflicting evidence indicating that imatinib may affect the expression of SLC22A1. However, thus far, no studies have investigated the effect of imatinib on SLC22A1 expression in an imatinib-sensitive cell line, which would mimic a typical clinical setting. Changes in the expression of SLC22A1 as a result of imatinib could potentially negate its usefulness as a prognostic marker. MATERIAL AND METHODS The K562 CML cell line was exposed to varying concentrations of imatinib for 24, 48, and 72 h and SLC22A1 expression was determined by quantitative real-time PCR. RESULTS Our findings suggest that imatinib affects the expression of SLC22A1 within 24 h in a non-linear concentration-dependent manner. CONCLUSIONS This is the first study to report on the short-term effect of imatinib on the expression of SLC22A1 in an imatinib-sensitive CML cell line. Our results suggest that imatinib affects SLC22A1 mRNA expression in a non-linear dose-dependent manner and that the changes in the expression of SLC22A1 as a result of the concentration of imatinib occur within 24 h of exposure to imatinib and remain stable thereafter for up to 72 h. PMID- 29567938 TI - Highly Expressed Granulocyte Colony-Stimulating Factor (G-CSF) and Granulocyte Colony-Stimulating Factor Receptor (G-CSFR) in Human Gastric Cancer Leads to Poor Survival. AB - BACKGROUND Chemotherapy for advanced gastric cancer (GC) patients has been the mainstay of therapy for many years. Although adding anti-angiogenic drugs to chemotherapy improves patient survival slightly, identifying anti-angiogenic therapy-sensitive patients remains challenging for oncologists. Granulocyte colony-stimulating factor (G-CSF) promotes tumor growth and angiogenesis, which can be minimized with the anti-G-CSF antibody. Thus, G-CSF might be a potential tumor marker. However, the effects of G-CSF and G-CSFR expression on GC patient survival remain unclear. MATERIAL AND METHODS Seventy GC tissue samples were collected for G-CSF and G-CSFR detection by immunohistochemistry. A total of 40 paired GC tissues and matched adjacent mucosa were used to measure the G-CSF and G-CSFR levels by ELISA. Correlations between G-CSF/G-CSFR and clinical characteristics, VEGF-A levels and overall survival were analyzed. Biological function and underlying mechanistic investigations were carried out using SGC7901 cell lines, and the effects of G-CSF on tumor proliferation, migration, and tube formation were examined. RESULTS The levels of G-CSFR were upregulated in GC tissues compared to normal mucosa tissues. Higher G-CSF expression was associated with later tumor stages and higher tumor VEGF-A and serum CA724 levels, whereas higher G-CSFR expression was associated with lymph node metastasis. Patients with higher G-CSF expression had shorter overall survival times. In vitro, G-CSF stimulated SGC7901 proliferation and migration through the JAK2/STAT3 pathway and accelerated HUVEC tube formation. CONCLUSIONS These data suggest that increased G CSF and G-CSFR in tumors leads to unfavorable outcomes for GC patients by stimulating tumor proliferation, migration, and angiogenesis, indicating that these factors are potential tumor targets for cancer treatment. PMID- 29567939 TI - Surface tension-assisted additive manufacturing. AB - The proliferation of computer-aided design and additive manufacturing enables on demand fabrication of complex, three-dimensional structures. However, combining the versatility of cell-laden hydrogels within the 3D printing process remains a challenge. Herein, we describe a facile and versatile method that integrates polymer networks (including hydrogels) with 3D-printed mechanical supports to fabricate multicomponent (bio)materials. The approach exploits surface tension to coat fenestrated surfaces with suspended liquid films that can be transformed into solid films. The operating parameters for the process are determined using a physical model, and complex geometric structures are successfully fabricated. We engineer, by tailoring the window geometry, scaffolds with anisotropic mechanical properties that compress longitudinally (~30% strain) without damaging the hydrogel coating. Finally, the process is amenable to high cell density encapsulation and co-culture. Viability (>95%) was maintained 28 days after encapsulation. This general approach can generate biocompatible, macroscale devices with structural integrity and anisotropic mechanical properties. PMID- 29567940 TI - Bax retrotranslocation potentiates Bcl-xL's antiapoptotic activity and is essential for switch-like transitions between MOMP competency and resistance. AB - The rapid, typically all-or-none process of mitochondrial outer membrane permeabilization (MOMP) constitutes a primary cell death decision that is controlled by the Bcl-2 family interactome. However, how strict all-or-none MOMP decisions are governed by and emanate from the dynamic interplay of pro- and antiapoptotic Bcl-2 family members remains incompletely understood. In particular, it is unclear to which extent the shuttling of Bcl-2 family species between lipid and aqueous phases contributes to regulating MOMP sensitivity. Here, we studied the interplay of tBid, Bax, and Bcl-xL, using a combined approach of deterministic mathematical modeling and retrospective as well as prospective experimental testing of model predictions. Systems modeling of the tBid-Bax interplay and their fluxes between cytosol and mitochondrial membranes reproduced experimental data on tBid-triggered Bax activation and oligomerization highly accurately. Extending these studies to analyze the cell-protective role of Bcl-xL strikingly revealed that the activity of Bcl-xL to retrotranslocate activated Bax from membranes back into the cytosol is essential to reproduce or correctly predict experimental outcomes. These included the potency of Bcl-xL in suppressing Bax oligomerization, its role in limiting Bax membrane recruitment, the resistance threshold to low concentrations of MOMP triggers as well as a response potentiaton arising from combinations of tBid and sensitizer BH3-only peptides. Importantly, retrotranslocation activity of Bcl-xL is necessary to strictly separate conditions of MOMP competency and resistance. Our results therefore identify Bax retrotranslocation by Bcl-xL as an indispensable component of the molecular switch by which Bcl-2 family members govern cellular death decisions. PMID- 29567942 TI - High temperature measurements and condensed matter analysis of the thermo physical properties of ThO2. AB - Values are presented for thermal conductivity, specific heat, spectral and total hemispherical emissivity of ThO2 (a potential nuclear fuel material) in a temperature range representative of a nuclear accident - 2000 K to 3050 K. For the first time direct measurements of thermal conductivity have been carried out on ThO2 at such high temperatures, clearly showing the property does not decrease above 2000 K. This could be understood in terms of an electronic contribution (arising from defect induced donor/acceptor states) compensating the degradation of lattice thermal conductivity. The increase in total hemispherical emissivity and visible/near-infrared spectral emissivity is consistent with the formation of donor/acceptor states in the band gap of ThO2. The electronic population of these defect states increases with temperature and hence more incoming photons (in the visible and near-infrared wavelength range) can be absorbed. A solid state physics model is used to interpret the experimental results. Specific heat and thermal expansion coefficient increase at high temperatures due to the formation of defects, in particular oxygen Frenkel pairs. Prior to melting a gradual increase to a maximum value is predicted in both properties. These maxima mark the onset of saturation of oxygen interstitial sites. PMID- 29567941 TI - Engineering enhanced cellobiohydrolase activity. AB - Glycoside Hydrolase Family 7 cellobiohydrolases (GH7 CBHs) catalyze cellulose depolymerization in cellulolytic eukaryotes, making them key discovery and engineering targets. However, there remains a lack of robust structure-activity relationships for these industrially important cellulases. Here, we compare CBHs from Trichoderma reesei (TrCel7A) and Penicillium funiculosum (PfCel7A), which exhibit a multi-modular architecture consisting of catalytic domain (CD), carbohydrate-binding module, and linker. We show that PfCel7A exhibits 60% greater performance on biomass than TrCel7A. To understand the contribution of each domain to this improvement, we measure enzymatic activity for a library of CBH chimeras with swapped subdomains, demonstrating that the enhancement is mainly caused by PfCel7A CD. We solve the crystal structure of PfCel7A CD and use this information to create a second library of TrCel7A CD mutants, identifying a TrCel7A double mutant with near-equivalent activity to wild-type PfCel7A. Overall, these results reveal CBH regions that enable targeted activity improvements. PMID- 29567943 TI - Peptide ion channel toxins from the bootlace worm, the longest animal on Earth. AB - Polypeptides from animal venoms have found important uses as drugs, pharmacological tools, and within biotechnological and agricultural applications. We here report a novel family of cystine knot peptides from nemertean worms, with potent activity on voltage-gated sodium channels. These toxins, named the alpha nemertides, were discovered in the epidermal mucus of Lineus longissimus, the 'bootlace worm' known as the longest animal on earth. The most abundant peptide, the 31-residue long alpha-1, was isolated, synthesized, and its 3D NMR structure determined. Transcriptome analysis including 17 species revealed eight alpha nemertides, mainly distributed in the genus Lineus. alpha-1 caused paralysis and death in green crabs (Carcinus maenas) at 1 ug/kg (~300 pmol/kg). It showed profound effect on invertebrate voltage-gated sodium channels (e.g. Blattella germanica Nav1) at low nanomolar concentrations. Strong selectivity for insect over human sodium channels indicates that alpha-nemertides can be promising candidates for development of bioinsecticidal agents. PMID- 29567944 TI - Insulin Regulates Adrenal Steroidogenesis by Stabilizing SF-1 Activity. AB - Development of metabolic syndrome is associated with hyperactivity of the HPA axis characterized by elevated levels of circulating adrenal hormones including cortisol and aldosterone. However, the molecular mechanism leading to the dysregulation of the HPA axis is not well elucidated. In this study, we found that insulin regulates adrenal steroidogenesis by increasing the expression and activity of steroidogenic factor 1 (SF-1) both in vitro and in vivo and this insulin effect was partly through inhibition of FoxO1. Specifically, insulin increased the protein and RNA levels of SF-1 and steroidogenic target genes. Further, adrenal SF-1 expression was significantly increased by hyperactivation of insulin signaling in mice. Together with the elevated SF-1 expression in adrenal glands, hyperactivation of insulin signaling led to increased aldosterone and corticosterone levels. On the other hand, suppressing the insulin signaling using streptozotocin markedly reduced the expression of adrenal SF-1 in mice. In addition, overexpression of FoxO1 significantly suppressed SF-1 and its steroidogenic target genes implying that the positive effect of insulin on SF-1 activity might be through suppression of FoxO1 in the adrenal gland. Taken together, these results indicate that insulin regulates adrenal steroidogenesis through coordinated control of SF-1 and FoxO1. PMID- 29567945 TI - The role of cuticular hydrocarbons in mate recognition in Drosophila suzukii. AB - Cuticular hydrocarbons (CHCs) play a central role in the chemical communication of many insects. In Drosophila suzukii, an economically important pest insect, very little is known about chemical communication and the possible role of CHCs. In this study, we identified 60 CHCs of Drosophila suzukii and studied their changes in function of age (maturation), sex and interactions with the opposite sex. We demonstrate that age (maturation) is the key factor driving changes in the CHC profiles. We then test the effect on courtship behaviour and mating of six CHCs, five of which were positively associated with maturation and one negatively. The results of these experiments demonstrate that four of the major CHC peaks with a chain length of 23 carbons, namely 9-tricosene (9-C23:1), 7 tricosene (7-C23:1), 5-tricosene (5-C23:1) and tricosane (n-C23), negatively regulated courtship and mating, even though all these compounds were characteristic for sexually mature flies. We then go on to show that this effect on courtship and mating is likely due to the disruption of the natural ratios in which these hydrocarbons occur in Drosophila suzukii. Overall, these results provide key insights into the cuticular hydrocarbon signals that play a role in D. suzukii mate recognition. PMID- 29567946 TI - Evidence for a dyadic motor plan in joint action. AB - What mechanisms distinguish interactive from non-interactive actions? To answer this question we tested participants while they took turns playing music with a virtual partner: in the interactive joint action condition, the participants played a melody together with their partner by grasping (C note) or pressing (G note) a cube-shaped instrument, alternating in playing one note each. In the non interactive control condition, players' behavior was not guided by a shared melody, so that the partner's actions and notes were irrelevant to the participant. In both conditions, the participant's and partner's actions were physically congruent (e.g., grasp-grasp) or incongruent (e.g., grasp-point), and the partner's association between actions and notes was coherent with the participant's or reversed. Performance in the non-interactive condition was only affected by physical incongruence, whereas joint action was only affected when the partner's action-note associations were reversed. This shows that task interactivity shapes the sensorimotor coding of others' behaviors, and that joint action is based on active prediction of the partner's action effects rather than on passive action imitation. We suggest that such predictions are based on Dyadic Motor Plans that represent both the agent's and the partner's contributions to the interaction goal, like playing a melody together. PMID- 29567947 TI - Metal-organic framework and Tenax-TA as optimal sorbent mixture for concurrent GC MS analysis of C1 to C5 carbonyl compounds. AB - We report a multi adsorbent-based method using combinations of metal-organic frameworks (MOFs) and a commercial sorbent Tenax-TA for sampling and thermal desorption (TD) gas chromatography-mass spectrometry (GC-MS) quantification of mixtures of six (C1 to C5) aldehydes. The feasibility of this approach was demonstrated along with the optical analytical conditions for maximum recovery. Optimal TD conditions for adsorption and desorption of aldehydes using MOF-5 (Zn based MOF)+ Tenax-TA were determined as -25 degrees C and 150 degrees C, respectively (purge volume: 100 ml). These conditions yielded good linearity (R2 = 0.997), precision, and high sensitivity. Analysis of the aldehyde mixtures yielded slightly smaller R2 values than the analysis of single species. Additionally, the performance of MOF-5+ Tenax-TA was compared with other combinations comprising of Cu-based MOF-199 and Zr-based MOF of UiO-66 topology. The results of the theoretical modelling analyses propose simultaneous interaction of the C=O group of aldehydes with open metal sites of the studied MOFs and van der Waals interaction of hydrocarbon "tail" of aldehydes with linkers of MOFs. The combined interactions significantly increased the enthalpy (eV/molecule) of formaldehyde adsorption on MOF. Our findings unravel a potential way to extend the application of GC-based detection toward concurrent analysis of organic molecules of variable sizes. PMID- 29567948 TI - Structural Implications of Mutations Conferring Rifampin Resistance in Mycobacterium leprae. AB - The rpoB gene encodes the beta subunit of RNA polymerase holoenzyme in Mycobacterium leprae (M. leprae). Missense mutations in the rpoB gene were identified as etiological factors for rifampin resistance in leprosy. In the present study, we identified mutations corresponding to rifampin resistance in relapsed leprosy cases from three hospitals in southern India which treat leprosy patients. DNA was extracted from skin biopsies of 35 relapse/multidrug therapy non-respondent leprosy cases, and PCR was performed to amplify the 276 bp rifampin resistance-determining region of the rpoB gene. PCR products were sequenced, and mutations were identified in four out of the 35 cases at codon positions D441Y, D441V, S437L and H476R. The structural and functional effects of these mutations were assessed in the context of three-dimensional comparative models of wild-type and mutant M. leprae RNA polymerase holoenzyme (RNAP), based on the recently solved crystal structures of RNAP of Mycobacterium tuberculosis, containing a synthetic nucleic acid scaffold and rifampin. The resistance mutations were observed to alter the hydrogen-bonding and hydrophobic interactions of rifampin and the 5' ribonucleotide of the growing RNA transcript. This study demonstrates that rifampin-resistant strains of M. leprae among leprosy patients in southern India are likely to arise from mutations that affect the drug-binding site and stability of RNAP. PMID- 29567949 TI - Ocimum flavone Orientin as a countermeasure for thrombocytopenia. AB - Thrombocytopenia or chronic depletion of platelets in blood, could create life threatening conditions in patients who receive aggressive systemic radiation and chemotherapy. Currently there are no approved agents for the rapid treatment of thrombocytopenia. In the present study, we demonstrate that administration of Orientin, a glycosidic flavonoid or dietary administration of Orientin containing Tulsi (Holy Basil) leaves, results in a significant increase in circulating platelets in a clinically relevant mouse model. No noticeable effects were observed on red blood cells, white blood cells or other hematologic parameters in treated animals indicating that Orientin specificity enhances platelet formation. The gene expression and immunophenotyping of bone marrow revealed that Orientin stimulates megakaryopoiesis specific transcriptional program. A significant increase in colony formation in bone marrow cells from Orientin pretreated mice further complemented the effect of Orientin on progenitor cells. The ex-vivo differentiation of irradiated human peripheral blood CD34+ stem cells demonstrated stimulatory effects of Orientin on megakaryocyte erythrocyte progenitors (MEP). The results show that Orientin, a non-toxic readily available natural product can counter platelet imbalances. Thrombocytopenia also develop as a consequence of multiple hematologic malignancies and side effects of treatments. Dietary supplementation of Orientin containing phytochemicals could be effective as countermeasures and viable therapeutics. PMID- 29567950 TI - Understanding the molecular biology of intervertebral disc degeneration and potential gene therapy strategies for regeneration: a review. AB - Intervertebral disc degeneration (IVDD) is a multi-factorial process characterized by phenotypic and genotypic changes, which leads to low back pain and disability. Prolonged imbalance between anabolism and catabolism in discs alters their composition resulting in progressive loss of proteoglycans and hydration leading to IVDD. The current managements for IVDD are only able to relieve the symptoms but do not address the underlying pathology of degeneration. Researchers have tried to find out differences between the aging and degeneration of the disc. Intense attempts are in progress for identifying the various factors responsible for disc degeneration, as well as strategies for regeneration. Recently biological approaches have gained thrust in the field of IVDD. The present review illustrates the current understanding of intervertebral disc degeneration and aims to put forth recent advancements in regeneration strategies involving different biological therapies such as growth factor, cell, and gene therapy. The potentials and consequences of these therapies are also extensively discussed along with citing the most suitable method, that is, the gene therapy in detail. Initially, gene therapy was mediated by viral vectors but recent progress has enabled researchers to opt for non-virus-mediated gene therapy methods, which ensure that there are no risks of mutagenicity and infection in target cells. With constant efforts, non-virus-mediated gene therapy may prove to be an extremely powerful tool in treatment of IVDD in future. PMID- 29567951 TI - Identification of potential key protein interaction networks of BK virus nephropathy in patients receiving kidney transplantation. AB - We aim to identify the key protein interaction networks and implicated pathways of BK virus nephropathy (BKVN) via bioinformatic methods. The microarray data GSE75693 of 30 patients with stable kidney transplantation and 15 with BKVN were downloaded and analyzed by using the limma package to identify differentially expressed genes (DEGs). Then the gene ontology (GO) functional enrichment analysis and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were done to investigate the molecular function (MF), biological process (BP), cellular components (CC) and pathways of DEGs. Finally, protein-protein interactions (PPIs) were constructed, and the hub proteins were identified. As a result, 249 up-regulated genes and 253 down-regulated genes of BKVN patients were selected based on criteria of P > 0.01 and fold change >2.0. GO and KEGG showed that DEGs were mainly located in nucleus and cytosol, and were implicated in the immune responses. In the PPI analysis, 26 up-regulated and 8 down-regulated proteins composed the pivotal interaction network. CXCL10, EGF and STAT1 were identified as hub proteins in BKVN. In conclusion, CXCL10, EGF and STAT1 may induce kidney injuries by promoting inflammation and prohibiting reparation of tissue damage in BKVN. PMID- 29567952 TI - Cystargamide B, a cyclic lipodepsipeptide with protease inhibitory activity from Streptomyces sp. AB - We identified a new cyclic lipodepsipeptide, cystargamide B (1), from the mycelial extract of a Kaempferia galanga rhizome-derived actinomycete strain, Streptomyces sp. PB013. The planar structure was elucidated based on high resolution fast-atom bombardment mass spectrometry (HRFABMS) spectroscopy and one dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectroscopic data. The absolute configurations of the constituent amino acids were determined using advanced Marfey's method. Cystargamide B (1) includes rare structural units: a 5-hydroxytryptophan residue and a 2,3-epoxy fatty acid side chain. Notably, cystargamide B (1) inhibited the protease activity of the NS2B/NS3 complex from dengue virus. PMID- 29567953 TI - Ruthenium(II)-enabled para-selective C-H difluoromethylation of anilides and their derivatives. AB - Transition-metal-catalyzed direct site-selective functionalization of arene C-H bonds has emerged as an innovative approach for building the core structure of pharmaceutical agents and other versatile complex compounds. However, para selective C-H functionalization has seldom been explored, only a few examples, such as steric-hindered arenes, electron-rich arenes, and substrates with a directing group, have been reported to date. Here we describe the development of a ruthenium-enabled para-selective C-H difluoromethylation of anilides, indolines, and tetrahydroquinolines. This reaction tolerates various substituted arenes, affording para-difluoromethylation products in moderate to good yields. Results of a preliminary study of the mechanism indicate that chelation-assisted cycloruthenation might play a role in the selective activation of para-CAr-H bonds. Furthermore, this method provides a direct approach for the synthesis of fluorinated drug derivatives, which has important application for drug discovery and development. PMID- 29567954 TI - A new caenagnathid dinosaur from the Upper Cretaceous Wangshi Group of Shandong, China, with comments on size variation among oviraptorosaurs. AB - The bone-beds of the Upper Cretaceous Wangshi Group in Zhucheng, Shandong, China are rich in fossil remains of the gigantic hadrosaurid Shantungosaurus. Here we report a new oviraptorosaur, Anomalipes zhaoi gen. et sp. nov., based on a recently collected specimen comprising a partial left hindlimb from the Kugou Locality in Zhucheng. This specimen's systematic position was assessed by three numerical cladistic analyses based on recently published theropod phylogenetic datasets, with the inclusion of several new characters. Anomalipes zhaoi differs from other known caenagnathids in having a unique combination of features: femoral head anteroposteriorly narrow and with significant posterior orientation; accessory trochanter low and confluent with lesser trochanter; lateral ridge present on femoral lateral surface; weak fourth trochanter present; metatarsal III with triangular proximal articular surface, prominent anterior flange near proximal end, highly asymmetrical hemicondyles, and longitudinal groove on distal articular surface; and ungual of pedal digit II with lateral collateral groove deeper and more dorsally located than medial groove. The holotype of Anomalipes zhaoi is smaller than is typical for Caenagnathidae but larger than is typical for the other major oviraptorosaurian subclade, Oviraptoridae. Size comparisons among oviraptorisaurians show that the Caenagnathidae vary much more widely in size than the Oviraptoridae. PMID- 29567955 TI - Dop1 enhances conspecific olfactory attraction by inhibiting miR-9a maturation in locusts. AB - Dopamine receptor 1 (Dop1) mediates locust attraction behaviors, however, the mechanism by which Dop1 modulates this process remains unknown to date. Here, we identify differentially expressed small RNAs associated with locust olfactory attraction after activating and inhibiting Dop1. Small RNA transcriptome analysis and qPCR validation reveal that Dop1 activation and inhibition downregulates and upregulates microRNA-9a (miR-9a) expression, respectively. miR-9a knockdown in solitarious locusts increases their attraction to gregarious volatiles, whereas miR-9a overexpression in gregarious locusts reduces olfactory attraction. Moreover, miR-9a directly targets adenylyl cyclase 2 (ac2), causing its downregulation at the mRNA and protein levels. ac2 responds to Dop1 and mediates locust olfactory attraction. Mechanistically, Dop1 inhibits miR-9a expression through inducing the dissociation of La protein from pre-miR-9a and resulting in miR-9a maturation inhibition. Our results reveal a Dop1-miR-9a-AC2 circuit that modulates locust olfactory attraction underlying aggregation. This study suggests that miRNAs act as key messengers in the GPCR signaling. PMID- 29567956 TI - The molecular mechanism for activating IgA production by Pediococcus acidilactici K15 and the clinical impact in a randomized trial. AB - IgA secretion at mucosal sites is important for host defence against pathogens as well as maintaining the symbiosis with microorganisms present in the small intestine that affect IgA production. In the present study, we tested the ability of 5 strains of lactic acid bacteria stimulating IgA production, being Pediococcus acidilactici K15 selected as the most effective on inducing this protective immunoglobulin. We found that this response was mainly induced via IL 10, as efficiently as IL-6, secreted by K15-stimulated dendritic cells. Furthermore, bacterial RNA was largely responsible for the induction of these cytokines; double-stranded RNA was a major causative molecule for IL-6 production whereas single-stranded RNA was critical factor for IL-10 production. In a randomized, double-blind, placebo-controlled clinical trial, ingestion of K15 significantly increased the secretory IgA (sIgA) concentration in saliva compared with the basal level observed before this intervention. These results indicate that functional lactic acid bacteria induce IL-6 and IL-10 production by dendritic cells, which contribute to upregulating the sIgA concentration at mucosal sites in humans. PMID- 29567957 TI - Cryo-EM structure of human mTOR complex 2. AB - Mechanistic target of rapamycin (mTOR) complex 2 (mTORC2) plays an essential role in regulating cell proliferation through phosphorylating AGC protein kinase family members, including AKT, PKC and SGK1. The functional core complex consists of mTOR, mLST8, and two mTORC2-specific components, Rictor and mSin1. Here we investigated the intermolecular interactions within mTORC2 complex and determined its cryo-electron microscopy structure at 4.9 A resolution. The structure reveals a hollow rhombohedral fold with a 2-fold symmetry. The dimerized mTOR serves as a scaffold for the complex assembly. The N-terminal half of Rictor is composed of helical repeat clusters and binds to mTOR through multiple contacts. mSin1 is located close to the FRB domain and catalytic cavity of mTOR. Rictor and mSin1 together generate steric hindrance to inhibit binding of FKBP12-rapamycin to mTOR, revealing the mechanism for rapamycin insensitivity of mTORC2. The mTOR dimer in mTORC2 shows more compact conformation than that of mTORC1 (rapamycin sensitive), which might result from the interaction between mTOR and Rictor mSin1. Structural comparison shows that binding of Rictor and Raptor (mTORC1 specific component) to mTOR is mutually exclusive. Our study provides a basis for understanding the assembly of mTORC2 and a framework to further characterize the regulatory mechanism of mTORC2 pathway. PMID- 29567958 TI - PHA-4/FoxA senses nucleolar stress to regulate lipid accumulation in Caenorhabditis elegans. AB - The primary function of the nucleolus is ribosome biogenesis, which is an extremely energetically expensive process. Failures in ribosome biogenesis cause nucleolar stress with an altered energy status. However, little is known about the underlying mechanism linking nucleolar stress to energy metabolism. Here we show that nucleolar stress is triggered by inactivation of RSKS-1 (ribosomal protein S6 kinase), RRP-8 (ribosomal RNA processing 8), and PRO-2/3 (proximal proliferation), all of which are involved in ribosomal RNA processing or inhibition of rDNA transcription by actinomycin D (AD), leading to excessive lipid accumulation in Caenorhabditis elegans. The transcription factor PHA-4/FoxA acts as a sensor of nucleolar stress to bind to and transactivate the expression of the lipogenic genes pod-2 (acetyl-CoA carboxylase), fasn-1 (fatty acid synthase), and dgat-2 (diacylglycerol O-acyltransferase 2), consequently promoting lipid accumulation. Importantly, inactivation of pha-4 or dgat-2 is sufficient to abolish nucleolar stress-induced lipid accumulation and prolonged starvation survival. The results revealed a distinct PHA-4-mediated lipogenesis pathway that senses nucleolar stress and shifts excessive energy for storage as fat. PMID- 29567959 TI - HIV-exposure, early life feeding practices and delivery mode impacts on faecal bacterial profiles in a South African birth cohort. AB - There are limited data on meconium and faecal bacterial profiles from African infants and their mothers. We characterized faecal bacterial communities of infants and mothers participating in a South African birth cohort. Stool and meconium specimens were collected from 90 mothers and 107 infants at birth, and from a subset of 72 and 36 infants at 4-12 and 20-28 weeks of age, respectively. HIV-unexposed infants were primarily exclusively breastfed at 4-12 (49%, 26/53) and 20-28 weeks (62%, 16/26). In contrast, HIV-exposed infants were primarily exclusively formula fed at 4-12 (53%; 10/19) and 20-28 weeks (70%, 7/10). Analysis (of the bacterial 16S rRNA gene sequences of the V4 hypervariable region) of the 90 mother-infant pairs showed that meconium bacterial profiles [dominated by Proteobacteria (89%)] were distinct from those of maternal faeces [dominated by Firmicutes (66%) and Actinobacteria (15%)]. Actinobacteria predominated at 4-12 (65%) and 20-28 (50%) weeks. HIV-exposed infants had significantly higher faecal bacterial diversities at both 4-12 (p = 0.026) and 20 28 weeks (p = 0.002). HIV-exposed infants had lower proportions of Bifidobacterium (p = 0.010) at 4-12 weeks. Maternal faecal bacterial profiles were influenced by HIV status, feeding practices and mode of delivery. Further longitudinal studies are required to better understand how these variables influence infant and maternal faecal bacterial composition.

AB - Molecules containing multiple bonds between atoms-most often in the form of olefins-are ubiquitous in nature, commerce, and science, and as such have a huge impact on everyday life. Given their prominence, over the last few decades, frequent attempts have been made to perturb the structure and reactivity of multiply-bound species through bending and twisting. However, only modest success has been achieved in the quest to completely twist double bonds in order to homolytically cleave the associated pi bond. Here, we present the isolation of double-bond-containing species based on boron, as well as their fully twisted diradical congeners, by the incorporation of attached groups with different electronic properties. The compounds comprise a structurally authenticated set of diamagnetic multiply-bound and diradical singly-bound congeners of the same class of compound. PMID- 29567961 TI - Rac1 in podocytes promotes glomerular repair and limits the formation of sclerosis. AB - Rac1, a Rho family member, is ubiquitously expressed and participates in various biological processes. Rac1 expression is induced early in podocyte injury, but its role in repair is unclear. To investigate the role of Rac1 expression in podocytes under pathological conditions, we used podocyte-specific Rac1 conditional knock-out (cKO) mice administered adriamycin (ADR), which causes nephrosis and glomerulosclerosis. Larger areas of detached podocytes, more adhesion of the GBM to Bowman's capsule, and a higher ratio of sclerotic glomeruli were observed in Rac1 cKO mice than in control mice, whereas no differences were observed in glomerular podocyte numbers in both groups after ADR treatment. The mammalian target of rapamycin (mTOR) pathway, which regulates the cell size, was more strongly suppressed in the podocytes of Rac1 cKO mice than in those of control mice under pathological conditions. In accordance with this result, the volumes of podocytes in Rac1 cKO mice were significantly reduced compared with those of control mice. Experiments using in vitro ADR-administered Rac1 knockdown podocytes also supported that a reduction in Rac1 suppressed mTOR activity in injured podocytes. Taken together, these data indicate that Rac1 associated mTOR activation in podocytes plays an important role in preventing the kidneys from developing glomerulosclerosis.

AB - Measurements of carbon isotope contents of plant organic matter provide important information in diverse fields such as plant breeding, ecophysiology, biogeochemistry and paleoclimatology. They are currently based on 13C/12C ratios of specific, whole metabolites, but we show here that intramolecular ratios provide higher resolution information. In the glucose units of tree-ring cellulose of 12 tree species, we detected large differences in 13C/12C ratios (>100/00) among carbon atoms, which provide isotopically distinct inputs to major global C pools, including wood and soil organic matter. Thus, considering position-specific differences can improve characterisation of soil-to-atmosphere carbon fluxes and soil metabolism. In a Pinus nigra tree-ring archive formed from 1961 to 1995, we found novel 13C signals, and show that intramolecular analysis enables more comprehensive and precise signal extraction from tree rings, and thus higher resolution reconstruction of plants' responses to climate change. Moreover, we propose an ecophysiological mechanism for the introduction of a 13C signal, which links an environmental shift to the triggered metabolic shift and its intramolecular 13C signature. In conclusion, intramolecular 13C analyses can provide valuable new information about long-term metabolic dynamics for numerous applications.

AB - PKD2L1, also termed TRPP3 from the TRPP subfamily (polycystic TRP channels), is involved in the sour sensation and other pH-dependent processes. PKD2L1 is believed to be a nonselective cation channel that can be regulated by voltage, protons, and calcium. Despite its considerable importance, the molecular mechanisms underlying PKD2L1 regulations are largely unknown. Here, we determine the PKD2L1 atomic structure at 3.38 A resolution by cryo-electron microscopy, whereby side chains of nearly all residues are assigned. Unlike its ortholog PKD2, the pore helix (PH) and transmembrane segment 6 (S6) of PKD2L1, which are involved in upper and lower-gate opening, adopt an open conformation. Structural comparisons of PKD2L1 with a PKD2-based homologous model indicate that the pore domain dilation is coupled to conformational changes of voltage-sensing domains (VSDs) via a series of pi-pi interactions, suggesting a potential PKD2L1 gating mechanism. PMID- 29567964 TI - Diffuse Myocardial Injuries are Present in Subclinical Hypothyroidism: A Clinical Study Using Myocardial T1-mapping Quantification. AB - Subclinical hypothyroidism (SHT) is a common disorder that may represent early thyroid dysfunction and is related to adverse cardiovascular events. However, myocardial injuries induced by SHT are difficult to detect. Our previous study demonstrated that the cardiac magnetic resonance (CMR) myocardial longitudinal relaxation time (T1) mapping technique is a useful tool for assessing diffuse myocardial injuries in overt hypothyroidism patients. This study was designed to detect whether diffuse myocardial injuries were present in SHT by using the T1 mapping technique. We found that SHT participants had significantly increased native T1 values within four segments of the left ventricle (all p < 0.01), especially patients with thyroid-stimulating hormone (TSH) levels >=10 uIU/mL, compared with those in the controls. In addition, the native T1 values were negatively correlated with free thyroxine (FT4) (r = -0.476, p = 0.003) and were positively correlated with TSH (r = 0.489, p = 0.002). Furthermore, left ventricular diastolic function estimated by the peak filling rate (PFR) was significantly lower in patients with TSH levels >=10 uIU/mL than that in the controls (p < 0.05). In conclusion, diffuse myocardial injuries were present in SHT, and T1 mapping may be a useful tool for evaluating mild myocardial injuries in SHT at an early stage. Our study is the first to confirm myocardial injuries in SHT patients using T1 mapping. PMID- 29567965 TI - Atomistic scale investigation of cation ordering and phase stability in Cs substituted Ba1.33Zn1.33Ti6.67O16, Ba1.33Ga2.66Ti5.67O16 and Ba1.33Al2.66Ti5.33O16 hollandite. AB - The titanate-based hollandite structure is proposed as an effective ceramic waste form for Cs-immobilization. In this study, quantum-mechanical calculations were used to quantify the impact of A-site and B-site ordering on the structural stability of hollandite with compositions BaxCsy(MzTi8-z)O16, where M = Zn2+, Ga3+, and Al3+. The calculated enthalpy of formation agrees with experimental measurements of related hollandite phases from melt solution calorimetry. Ground state geometry optimizations show that, for intermediate compositions (e.g., CsBaGa6Ti18O48), the presence of both Cs and Ba in the A-site tunnels is not energetically favored. However, the decay heat generated during storage of the Cs containing waste form may overcome the energetics of Ba and Cs mixing in the tunnel structure of hollandite. The ability of the hollandite structure to accommodate the radioparagenesis of Cs to Ba is critical for long term performance of the waste. For the first time, B-site ordering was observed along the tunnel direction ([001] zone axis) for the Ga-hollandite compositions, as well as the intermediate Al-hollandite composition. These compositionally dependent structural features, and associated formation enthalpies, are of importance to the stability and radiation damage tolerance of ceramic waste forms.

PMID- 29567966 TI - Intravenous administration of anti-inflammatory mesenchymal stem cell spheroids reduces chronic alcohol intake and abolishes binge-drinking. AB - Chronic alcohol intake leads to neuroinflammation and astrocyte dysfunction, proposed to perpetuate alcohol consumption and to promote conditioned relapse like binge drinking. In the present study, human mesenchymal stem cells (MSCs) were cultured in 3D-conditions to generate MSC-spheroids, which greatly increased MSCs anti-inflammatory ability and reduced cell volume by 90% versus conventionally 2D-cultured MSCs, enabling their intravenous administration and access to the brain. It is shown, in an animal model of chronic ethanol intake and relapse-drinking, that both the intravenous and intra-cerebroventricular administration of a single dose of MSC-spheroids inhibited chronic ethanol intake and relapse-like drinking by 80-90%, displaying significant effects over 3-5 weeks. The MSC-spheroid administration fully normalized alcohol-induced neuroinflammation, as shown by a reduced astrocyte activation, and markedly increased the levels of the astrocyte Na-glutamate (GLT-1) transporter. This research suggests that the intravenous administration of MSC-spheroids may constitute an effective new approach for the treatment of alcohol-use disorders. PMID- 29567968 TI - Coherent all-optical transistor based on frustrated total internal reflection. AB - This study aims to design an all-optical transistor based on tunneling of light through frustrated total internal reflection. Under total internal reflection, the electromagnetic wave penetrates into the lower index medium. If a medium with high refractive index is placed close to the boundary of the first one, a portion of light leaks into the second medium. The penetrated electromagnetic field distribution can be influenced by another coherent light in the low refractive index medium via interference, leading to light amplification. Upon this technique, we introduce coherent all-optical transistors based on photonic crystal structures. Subsequently, we inspect the shortest pulse which is amplified by the designed system and also its terahertz repetition rate. We will show that such a system can operate in a cascade form. Operating in terahertz range and the amplification efficiency of around 20 are of advantages of this system. PMID- 29567969 TI - Fast first-photon ghost imaging. AB - Conventional imaging at low light levels requires hundreds of detected photons per pixel to suppress the Poisson noise for accurate reflectivity inference. We propose a high-efficiency photon-limited imaging technique, called fast first photon ghost imaging, which recovers the image by conditional averaging of the reference patterns selected by the first-photon detection signal. Our technique merges the physics of low-flux measurements with the framework of computational ghost imaging. Experimental results demonstrate that it can reconstruct an image from less than 0.1 detected photon per pixel, which is three orders of magnitude less than conventional imaging techniques. A signal-to-noise ratio model of the system is established for noise analysis. With less data manipulation and shorter time requirements, our technique has potential applications in many fields, ranging from biological microscopy to remote sensing. PMID- 29567970 TI - Data-based Decision Rules to Personalize Depression Follow-up. AB - Depression is a common mental illness with complex and heterogeneous progression dynamics. Risk grouping of depression treatment population based on their longitudinal patterns has the potential to enable cost-effective monitoring policy design. This paper establishes a rule-based method to identify a set of risk predictive patterns from person-level longitudinal disease measurements by integrating the data transformation, rule discovery and rule evaluation. We further extend the identified rules to create rule-based monitoring strategies to adaptively monitor individuals with different disease severities. We applied the rule-based method on an electronic health record (EHR) dataset of depression treatment population containing person-level longitudinal Patient Health Questionnaire (PHQ)-9 scores for assessing depression severity. 12 risk predictive rules are identified, and the rule-based prognostic model based on identified rules enables more accurate prediction of disease severity than other prognostic models including RuleFit, logistic regression and Support Vector Machine. Two rule-based monitoring strategies outperform the latest PHQ-9 based monitoring strategy by providing higher sensitivity and specificity. The rule based method can lead to a better understanding of disease dynamics, achieving more accurate prognostics of disease progressions, personalizing follow-up intervals, and designing cost-effective monitoring of patients in clinical practice.

PMID- 29567971 TI - Molecular basis of binding between the global post-transcriptional regulator CsrA and the T3SS chaperone CesT. AB - The T3SS chaperone CesT is recently shown to interact with the post transcriptional regulator CsrA to modulate post-attachment signaling in enteropathogenic and enterohemorrhagic Escherichia coli. The molecular basis of the CesT/CsrA binding, however, remains elusive. Here, we show that CesT and CsrA both created two ligand binding sites in their homodimers, forming irregular multimeric complexes in solution. Through construction of a recombinant CsrA dimer (Re-CsrA) that contains a single CesT binding site, the atomic binding features between CesT and CsrA are delineated via the structure of the CesT/Re CsrA complex. In contrast to a previously reported N-terminally swapped dimer form, CesT adopts a dimeric architecture with a swapped C-terminal helix for CsrA engagement. In CsrA, CesT binds to a surface patch that extensively overlaps with its mRNA binding site. The binding mode therefore justifies a mechanism of CsrA modulation by CesT via competitive inhibition of the CsrA/mRNA interactions.

AB - Isocitrate dehydrogenase (IDH) 2 participates in the TCA cycle and catalyzes the conversion of isocitrate to alpha-ketoglutarate and NADP+ to NADPH. In the mitochondria, IDH2 also plays a key role in protecting mitochondrial components from oxidative stress by supplying NADPH to both glutathione reductase (GSR) and thioredoxin reductase 2 (TXNRD2). Here, we report that loss of Idh2 accelerates age-related hearing loss, the most common form of hearing impairment, in male mice. This was accompanied by increased oxidative DNA damage, increased apoptotic cell death, and profound loss of spiral ganglion neurons and hair cells in the cochlea of 24-month-old Idh2-/- mice. In young male mice, loss of Idh2 resulted in decreased NADPH redox state and decreased activity of TXNRD2 in the mitochondria of the inner ear. In HEI-OC1 mouse inner ear cell lines, knockdown of Idh2 resulted in a decline in cell viability and mitochondrial oxygen consumption. This was accompanied by decreased NADPH redox state and decreased activity of TXNRD2 in the mitochondria of the HEI-OC1 cells. Therefore, IDH2 functions as the principal source of NADPH for the mitochondrial thioredoxin antioxidant defense and plays an essential role in protecting hair cells and neurons against oxidative stress in the cochlea of male mice. PMID- 29567976 TI - SpliceDetector: a software for detection of alternative splicing events in human and model organisms directly from transcript IDs. AB - In eukaryotes, different combinations of exons lead to multiple transcripts with various functions in protein level, in a process called alternative splicing (AS). Unfolding the complexity of functional genomics through genome-wide profiling of AS and determining the altered ultimate products provide new insights for better understanding of many biological processes, disease progress as well as drug development programs to target harmful splicing variants. The current available tools of alternative splicing work with raw data and include heavy computation. In particular, there is a shortcoming in tools to discover AS events directly from transcripts. Here, we developed a Windows-based user friendly tool for identifying AS events from transcripts without the need to any advanced computer skill or database download. Meanwhile, due to online working mode, our application employs the updated SpliceGraphs without the need to any resource updating. First, SpliceGraph forms based on the frequency of active splice sites in pre-mRNA. Then, the presented approach compares query transcript exons to SpliceGraph exons. The tool provides the possibility of statistical analysis of AS events as well as AS visualization compared to SpliceGraph. The developed application works for transcript sets in human and model organisms. PMID- 29567977 TI - Magnetic field effect on the energy levels of an exciton in a GaAs quantum dot: Application for excitonic lasers. AB - The problem of an exciton trapped in a Gaussian quantum dot (QD) of GaAs is studied in both two and three dimensions in the presence of an external magnetic field using the Ritz variational method, the 1/N expansion method and the shifted 1/N expansion method. The ground state energy and the binding energy of the exciton are obtained as a function of the quantum dot size, confinement strength and the magnetic field and compared with those available in the literature. While the variational method gives the upper bound to the ground state energy, the 1/N expansion method gives the lower bound. The results obtained from the shifted 1/N expansion method are shown to match very well with those obtained from the exact diagonalization technique. The variation of the exciton size and the oscillator strength of the exciton are also studied as a function of the size of the quantum dot. The excited states of the exciton are computed using the shifted 1/N expansion method and it is suggested that a given number of stable excitonic bound states can be realized in a quantum dot by tuning the quantum dot parameters. This can open up the possibility of having quantum dot lasers using excitonic states. PMID- 29567978 TI - Conical Refraction Bottle Beams for Entrapment of Absorbing Droplets. AB - Conical refraction (CR) optical bottle beams for photophoretic trapping of airborne absorbing droplets are introduced and experimentally demonstrated. CR describes the circular split-up of unpolarised light propagating along an optical axis in a biaxial crystal. The diverging and converging cones lend themselves to the construction of optical bottle beams with flexible entry points. The interaction of single inkjet droplets with an open or partly open bottle beam is shown implementing high-speed video microscopy in a dual-view configuration. Perpendicular image planes are visualized on a single camera chip to characterize the integral three-dimensional movement dynamics of droplets. We demonstrate how a partly opened optical bottle transversely confines liquid objects. Furthermore we observe and analyse transverse oscillations of absorbing droplets as they hit the inner walls and simultaneously measure both transverse and axial velocity components. PMID- 29567979 TI - Kinematic features in patients with lateral discoid meniscus injury during walking. AB - At present, there few studies on the kinematic features of lateral discoid meniscus injury. In this study, a motion capture system was used to investigate the motion characteristics of knees with lateral discoid meniscus after injury, and the differences between the knees with lateral meniscus and intact knees were compared. Fourteen patients diagnosed with unilateral lateral discoid meniscus injury, fourteen patients diagnosed with unilateral lateral meniscus injury, and fourteen normal subjects with healthy knees were recruited and grouped. Through kinematic gait analysis, it was found that the subjects in the two groups with meniscus injuries exhibited significantly smaller ranges of rotation and translation than those with healthy knees on the sagittal, coronal, and horizontal planes, but not in proximal-distal translation. Maximum lateral tibial translation and maximum internal tibial rotation in the knees with lateral discoid meniscus injury were significantly decreased compared to those with lateral meniscus injury. The results show that the kinematic features of knees with lateral discoid meniscus injury are statistically different than those of healthy knees and knees with lateral meniscus injury. This study provides an important reference for the dynamic function of knees with lateral discoid meniscus injury.

PMID- 29567981 TI - Population attributable fractions continue to unmask the power of prevention. AB - The population attributable fraction is a critical driver of evidence-based cancer prevention. With an increasing recognition of the need for high-level investment in cancer control, there is an overwhelming need for a new generation of descriptive studies that globally promote the long-term public health and economic benefits of cancer prevention. PMID- 29567982 TI - The fraction of cancer attributable to modifiable risk factors in England, Wales, Scotland, Northern Ireland, and the United Kingdom in 2015. AB - BACKGROUND: Changing population-level exposure to modifiable risk factors is a key driver of changing cancer incidence. Understanding these changes is therefore vital when prioritising risk-reduction policies, in order to have the biggest impact on reducing cancer incidence. UK figures on the number of risk factor attributable cancers are updated here to reflect changing behaviour as assessed in representative national surveys, and new epidemiological evidence. Figures are also presented by UK constituent country because prevalence of risk factor exposure varies between them. METHODS: Population attributable fractions (PAFs) were calculated for combinations of risk factor and cancer type with sufficient/convincing evidence of a causal association. Relative risks (RRs) were drawn from meta-analyses of cohort studies where possible. Prevalence of exposure to risk factors was obtained from nationally representative population surveys. Cancer incidence data for 2015 were sourced from national data releases and, where needed, personal communications. PAF calculations were stratified by age, sex and risk factor exposure level and then combined to create summary PAFs by cancer type, sex and country. RESULTS: Nearly four in ten (37.7%) cancer cases in 2015 in the UK were attributable to known risk factors. The proportion was around two percentage points higher in UK males (38.6%) than in UK females (36.8%). Comparing UK countries, the attributable proportion was highest in Scotland (41.5% for persons) and lowest in England (37.3% for persons). Tobacco smoking contributed by far the largest proportion of attributable cancer cases, followed by overweight/obesity, accounting for 15.1% and 6.3%, respectively, of all cases in the UK in 2015. For 10 cancer types, including two of the five most common cancer types in the UK (lung cancer and melanoma skin cancer), more than 70% of UK cancer cases were attributable to known risk factors. CONCLUSION: Tobacco and overweight/obesity remain the top contributors of attributable cancer cases. Tobacco smoking has the highest PAF because it greatly increases cancer risk and has a large number of cancer types associated with it. Overweight/obesity has the second-highest PAF because it affects a high proportion of the UK population and is also linked with many cancer types. Public health policy may seek to mitigate the level of harm associated with exposure or reduce exposure levels-both approaches may effectively impact cancer incidence. Differences in PAFs between countries and sexes are primarily due to varying prevalence of exposure to risk factors and varying proportions of specific cancer types. This variation in turn is affected by socio-demographic differences which drive differences in exposure to theoretically avoidable 'lifestyle' factors. PAFs at UK country level have not been available previously and they should be used by policymakers in devolved nations. PAFs are estimates based on the best available data, limitations in those data would generally bias toward underestimation of PAFs. Regular collection of risk factor exposure prevalence data which corresponds with epidemiological evidence is vital for analyses like this and should remain a priority for the UK Government and devolved Administrations.

PMID- 29567984 TI - Genetic homogeneity of the invasive lionfish across the Northwestern Atlantic and the Gulf of Mexico based on Single Nucleotide Polymorphisms. AB - Despite the devastating impact of the lionfish (Pterois volitans) invasion on NW Atlantic ecosystems, little genetic information about the invasion process is available. We applied Genotyping by Sequencing techniques to identify 1,220 single nucleotide polymorphic sites (SNPs) from 162 lionfish samples collected between 2013 and 2015 from two areas chronologically identified as the first and last invaded areas in US waters: the east coast of Florida and the Gulf of Mexico. We used population genomic analyses, including phylogenetic reconstruction, Bayesian clustering, genetic distances, Discriminant Analyses of Principal Components, and coalescence simulations for detection of outlier SNPs, to understand genetic trends relevant to the lionfish's long-term persistence. We found no significant differences in genetic structure or diversity between the two areas (FST p-values > 0.01, and t-test p-values > 0.05). In fact, our genomic analyses showed genetic homogeneity, with enough gene flow between the east coast of Florida and Gulf of Mexico to erase previous signals of genetic divergence detected between these areas, secondary spreading, and bottlenecks in the Gulf of Mexico. These findings suggest rapid genetic changes over space and time during the invasion, resulting in one panmictic population with no signs of divergence between areas due to local adaptation.

AB - Reinvestigation of the Kushk and Chahmir areas (Bafq and Behabad regions) of central Iran has yielded a diverse assemblage of Ediacaran fossils, including several new species, just prior to the Cambrian explosion of complex animals. The Kushk series consists mainly of shallow marine carbonate deposits followed by deep-water calcareous marine shales. Ediacaran fossils occur commonly in the shale deposits and include biostratigraphically-important taxa Cloudina and Corumbella, which confirms a latest Ediacaran age for these deposits, the youngest examples of Kimberellomorphs (stem-group molluscs) that helps bridge the gap between their first occurrence in the middle-Ediacaran and the crown diversification in the Cambrian, and likely sponges, which are rare prior to the Cambrian.

AB - Rapid economic development in China has caused marked changes in people's lifestyles and medical technology. Exploration of stroke subtype trends is necessary to provide physicians with vital insight for early diagnosis and treatment. We included stroke patients admitted from 2006 to 2015. Trends in stroke subtypes and vascular risk factors were investigated. There were 5521 patients, including 4534 (82.1%) ischemic stroke (IS), 813 (14.7%) intracerebral hemorrhage (ICH) and 174 (3.2%) subarachnoid hemorrhage (SAH) patients. The proportion of IS was increasing and proportions of ICH and SAH were decreasing (P < 0.001). Onset age and hypertension remained stable in stroke subtypes. In IS patients, large artery atherosclerosis (LAA) strokes increased from 17.0% to 30.8% in the first 7 years and ultimately decreased to 24.1%. Small vessel disease (SVD) strokes increased from 15.5% to 39.6%, undetermined etiology (UE) strokes decreased from 52.7% to 26.0%, others remained stable. The levels of low density lipoprotein declined significantly, and an increased number of patients underwent intracranial artery examinations (P < 0.001). In conclusion, proportions of stroke subtypes changed significantly. Anti-hypertension therapy needs to be reinforced to control ICH, SAH and SVD ischemic stroke incidences. The etiologic detection of IS increased and lipid-lowing therapy was effective, cardioembolism detections should be reinforced.

AB - Tumor-associated macrophages (TAMs) are a major component of the tumor microenvironment and have been shown to contribute to tumor aggressiveness. However, the detailed mechanisms underlying the pro-metastatic effect of TAMs on gastric cancer are not clearly defined. Here, we show that TAMs are enriched in gastric cancer. TAMs are characterized by M2-polarized phenotype and promote migration of gastric cancer cells in vitro and in vivo. Furthermore, we find that M2-derived exosomes determine the TAMs-mediated pro-migratory activity. Using mass spectrometry, we identify that apolipoprotein E (ApoE) is highly specific and effective protein in M2 macrophages-derived exosomes. Moreover, TAMs are uniquely immune cells population expressed ApoE in gastric cancer microenvironment. However, exosomes derived from M2 macrophages of Apoe -/- mice have no significant effect on the migration of gastric cancer cells in vitro and in vivo. Mechanistically, M2 macrophage-derived exosomes mediate an intercellular transfer of ApoE-activating PI3K-Akt signaling pathway in recipient gastric cancer cells to remodel the cytoskeleton-supporting migration. Collectively, our findings signify that the exosome-mediated transfer of functional ApoE protein from TAMs to the tumor cells promotes the migration of gastric cancer cells.

AB - Amines bearing gamma-stereocenters are highly important structural motifs in many biologically active compounds. However, reported enantioselective syntheses of these molecules are indirect and often require multiple steps. Herein, we report a general asymmetric route for the one-pot synthesis of chiral gamma-branched amines through the highly enantioselective isomerization of allylamines, followed by enamine exchange and subsequent chemoselective reduction. This protocol is suitable for establishing various tertiary stereocenters, including those containing dialkyl, diaryl, cyclic, trifluoromethyl, difluoromethyl, and silyl substituents, which allows for a rapid and modular synthesis of many chiral gamma branched amines. To demonstrate the synthetic utility, Terikalant and Tolterodine are synthesized using this method with high levels of enantioselectivity.

AB - Although many articles have uncovered that Wnt signaling is involved in radioresistance, the mechanism is rarely reported. Here we generated two radioresistant cells rECA109 and rKyse150 from parental esophageal cancer cells ECA109 and Kyse150. We then found that Wnt signaling activity was higher in radioresistant cells and was further activated upon ionizing radiation (IR) exposure. In addition, radioresistant cells acquired epithelial-to-mesenchymal transition (EMT) properties and stem quality. Wnt signaling was then found to be involved in radioresistance by promoting DNA damage repair. In our present study, high-mobility group box 1 protein (HMGB1), a chromatin-associated protein, was firstly found to be transactivated by Wnt signaling and mediate Wnt-induced radioresistance. The role of HMGB1 in the regulation of DNA damage repair with the activation of DNA damage checkpoint response in response to IR was the main cause of HMGB1-induced radioresistance. PMID- 29567991 TI - BEARscc determines robustness of single-cell clusters using simulated technical replicates. AB - Single-cell messenger RNA sequencing (scRNA-seq) has emerged as a powerful tool to study cellular heterogeneity within complex tissues. Subpopulations of cells with common gene expression profiles can be identified by applying unsupervised clustering algorithms. However, technical variance is a major confounding factor in scRNA-seq, not least because it is not possible to replicate measurements on the same cell. Here, we present BEARscc, a tool that uses RNA spike-in controls to simulate experiment-specific technical replicates. BEARscc works with a wide range of existing clustering algorithms to assess the robustness of clusters to technical variation. We demonstrate that the tool improves the unsupervised classification of cells and facilitates the biological interpretation of single cell RNA-seq experiments.

AB - Crotamine, originally isolated from rattlesnake venom, has been extensively studied due to its pleiotropic biological properties, and special attention has been paid to its antitumor activity. However, long-term treatment with crotamine was accompanied by a reduction in animal body weight gain and by increases in glucose tolerance. As cancer is commonly associated with cachexia, to preclude the possible cancer cachexia-like effect of crotamine, herein this polypeptide was administered in healthy wild-type C57/BL6 mice by the oral route daily, for 21 days. Reduced body weight gain, in addition to decreased white adipose tissue (WAT) and increased brown adipose tissue (BAT) mass were observed in healthy animals in the absence of tumor. In addition, we observed improved glucose tolerance and increased insulin sensitivity, accompanied by a reduction of plasma lipid levels and decreased levels of biomarkers of liver damage and kidney disfunctions. Importantly, long-term treatment with crotamine increased the basal metabolic rate in vivo, which was consistent with the increased expression of thermogenic markers in BAT and WAT. Interestingly, cultured brown adipocyte cells induced to differentiation in the presence of crotamine also showed increases in some of these markers and in lipid droplets number and size, indicating increased brown adipocyte maturation.

AB - The malaria parasite Plasmodium falciparum proliferates in the blood stream where the host immune system is most active. To escape from host immunity, P. falciparum has developed a number of evasion mechanisms. Serine repeat antigen 5 (SERA5) is a blood stage antigen highly expressed at late trophozoite and schizont stages. The P47 N-terminal domain of SERA5, the basis of SE36 antigen of the blood stage vaccine candidate under clinical trials, covers the merozoite surface. Exploring the role of the P47 domain, screening of serum proteins showed that vitronectin (VTN) directly binds to 20 residues in the C-terminal region of SE36. VTN co-localized with P47 domain in the schizont and merozoite stages. Phagocytosis assay using THP-1 cells demonstrated that VTN bound to SE36 prevented engulfment of SE36-beads. In addition, several serum proteins localized on the merozoite surface, suggesting that host proteins camouflage merozoites against host immunity via binding to VTN.

AB - The physical and biological roles of mesoscale eddies in Japanese eel larvae dispersal are investigated using a three-dimensional (3D) particle-tracking method, with a focus on the Subtropical Counter Current eddies of the western North Pacific Ocean. Virtual eel larvae (v-larvae) movements depends on the 3D ocean currents and active swimming behavior, including vertical swimming (diel vertical migration), horizontal directional swimming toward settlement habitat, and horizontal swimming toward available food. V-larvae are able to remain in eddies passively due to mesoscale eddy nonlinearity and/or actively due to attraction to rich food supplies. Thus, both physical trapping and biological attraction to food contribute to the retention of v-larvae in eddies. Physical trapping dominates the retention of v-larvae whose swimming speeds are slower than the eddy propagation speed, whereas biological food attraction prevails in the retention of v-larvae swimming faster than eddy propagation. Food availability differs between warm (anti-cyclonic) and cold (cyclonic) eddies, with the latter providing a richer food supply. Fish larvae that are retained for longer durations in cold eddies (shorter durations in warm eddies) are able to obtain more food and potentially grow faster, which enhances survival rates.

AB - Nuclear receptor binding protein 1 (NRBP1) is a ubiquitously expressed and highly conserved pseudokinase that has important roles in cellular homoeostasis. Despite recent advances in understanding the biology of NRBP1, the role of NRBP1 and its underlying mechanism in colorectal cancer (CRC) have not been fully elucidated. In the present study, we observed that NRBP1 expression levels were significantly reduced in CRC tissues compared with corresponding adjacent normal tissues, and high NRBP1 expression correlated with better prognosis in CRC. Overexpression of NRBP1 inhibited CRC cell proliferation and promoted apoptosis in vitro and in vivo. In contrast, knockdown of NRBP1 expression increased cell proliferation and decreased the percentage of apoptotic cells. Moreover, overexpression of NRBP1 activated caspase-dependent intrinsic apoptosis. In addition, we further discovered that NRBP1 regulated the apoptotic pathway through interaction with JNK. Finally, NRBP1 overexpression led to attenuated CRC growth in a xenograft mouse model. Our study illustrates the suppressor role of NRBP1 in CRC and provides a potential therapeutic target. PMID- 29567998 TI - System-wide coordinates of higher order functions in host-pathogen environment upon Mycobacterium tuberculosis infection. AB - Molecular signatures and their interactions behind the successful establishment of infection of Mycobacterium tuberculosis (Mtb) inside macrophage are largely unknown. In this work, we present an inter-system scale atlas of the gene expression signatures, their interactions and higher order gene functions of macrophage-Mtb environment at the time of infection. We have carried out large scale meta-analysis of previously published gene expression microarray studies andhave identified a ranked list of differentially expressed genes and their higher order functions in intracellular Mtb as well as the infected macrophage. Comparative analysis of gene expression signatures of intracellular Mtb with the in vitro dormant Mtb at different hypoxic and oxidative stress conditions led to the identification of the large number of Mtb functional groups, namely operons, regulons and pathways that were common and unique to the intracellular environment and dormancy state. Some of the functions that are specific to intracellular Mtb are cholesterol degradation and biosynthesis of immunomodulatory phenolic compounds. The molecular signatures we have identified to be involved in adaptation to different stress conditions in macrophage environment may be critical for designing therapeutic interventions against tuberculosis. And, our approach may be broadly applicable for investigating other host-pathogen interactions. PMID- 29567999 TI - Operating length and velocity of human vastus lateralis muscle during walking and running. AB - According to the force-length-velocity relationships, the muscle force potential during locomotion is determined by the operating fibre length and velocity. We measured fascicle and muscle-tendon unit length and velocity as well as the activity of the human vastus lateralis muscle (VL) during walking and running. Furthermore, we determined the VL force-length relationship experimentally and calculated the force-length and force-velocity potentials (i.e. fraction of maximum force according to the force-length-velocity curves) for both gaits. During the active state of the stance phase, fascicles showed significantly (p < 0.05) smaller length changes (walking: 9.2 +/- 4.7% of optimal length (L0); running: 9.0 +/- 8.4%L0) and lower velocities (0.46 +/- 0.36 L0/s; 0.03 +/- 0.83 L0/s) compared to the muscle-tendon unit (walking: 19.7 +/- 5.3%L0, -0.94 +/- 0.32 L0/s; running: 34.5 +/- 5.8%L0, -2.59 +/- 0.41 L0/s). The VL fascicles operated close to optimum length (L0 = 9.4 +/- 0.11 cm) in both walking (8.6 +/- 0.14 cm) and running (10.1 +/- 0.19 cm), resulting in high force-length (walking: 0.92 +/- 0.08; running: 0.91 +/- 0.14) and force-velocity (0.91 +/- 0.08; 0.97 +/ 0.13) potentials. For the first time we demonstrated that, in contrast to the current general conception, the VL fascicles operate almost isometrically and close to L0 during the active state of the stance phase of walking and running. The findings further verify an important contribution of the series-elastic element to VL fascicle dynamics. PMID- 29568000 TI - Are CSNK2A1 gene mutations associated with retinal dystrophy? Report of a patient carrier of a novel de novo splice site mutation. PMID- 29568002 TI - Application of distribution functions in accurate determination of interdiffusion coefficients. AB - Diffusion couple technique in combination with the Boltzmann-Matano method is the widely used approach to evaluate the interdiffusion coefficients in the target systems. However, the quality of the evaluated interdiffusion coefficients due to the Boltzmann-Matano method strongly depends on the fitting degree of the utilized continuous function to the discrete experimental composition profiles. In this paper, the application of different types of distribution functions is proposed to solve this problem. For the simple D-c relations, the normal, pseudo normal, skew normal, pseudo-skew normal distributions can be employed, while for the complex D-c relations, the superposed distributions should be used. Even for the cases with uphill diffusion, the combined superposition of distributions may be chosen. Through validation in several benchmarks and real alloy systems, accurate diffusion coefficients are proved to be successfully obtained by using the distribution functions. It is anticipated that the Boltzmann-Matano method together with the distribution functions may serve as the general solution for determining the accurate interdiffusion coefficients in different materials. PMID- 29568001 TI - Dysosteosclerosis is also caused by TNFRSF11A mutation. AB - Dysosteosclerosis (DOS) is a form of sclerosing bone disease characterized by irregular osteosclerosis and platyspondyly. Its mode of inheritance is autosomal recessive. SLC29A3 mutations have been reported as the causal gene in two DOS families, however, genetic heterogeneity has been suggested. By whole-exome sequencing in a Turkish patient with DOS, we found a novel splice-site mutation in TNFRSF11A. TNFRSF11A mutations have previously been reported in two autosomal dominant diseases (osteolysis, familial expansile and Paget disease of bone 2, early-onset) and an autosomal recessive disease (osteopetrosis, autosomal recessive 7). The biallelic mutation, c.616+3A>G, identified in our study was located in the splice donor site of intron 6 of TNFRSF11A. Exon trapping assay indicated the mutation caused skipping of exon 6, which was predicted to induce a frame-shift and an early termination codon in all known alternative transcript variants of TNFRSF11A. The predicted effect of the mutation for the isoforms was different from those of the previously reported mutations, which could explain the difference of their phenotypes. Thus, our study identified the second disease gene for DOS. TNFRSF11A isoforms may have the different roles in skeletal development and metabolism. PMID- 29568003 TI - Whey protein lowers systolic blood pressure and Ca-caseinate reduces serum TAG after a high-fat meal in mildly hypertensive adults. AB - Epidemiological studies show an inverse association between dairy consumption and blood pressure (BP) but there are few data on the postprandial effects of milk proteins. This study examined their effects, compared to maltodextrin, on postprandial BP and other CVD risk markers in volunteers with mild and pre hypertension over an 8 h period. In this double-blinded, randomised, cross-over, controlled study 27 adults ingested a high-fat, isoenergetic breakfast and lunch with 28 g whey protein, 28 g Ca-caseinate or 27 g maltodextrin. Whey protein reduced systolic BP compared with Ca-caseinate (-15.2 +/- 13.6 mmHg) and maltodextrin (-23.4 +/- 10.5 mmHg) up to 5 h post-ingestion. There was an improvement in arterial stiffness after whey protein compared with maltodextrin (incremental Area Under the Curve- iAUC0-8h: +14.4 +/- 6.2%). Despite similar glucose levels after both whey protein and Ca-caseinate, whey protein induced a higher insulin response than Ca-caseinate (iAUC0-8h: +219.5 +/- 54.6 pmol/L). Ca caseinate induced less suppression of non-esterified fatty acids than whey protein (iAUC0-5h: -58.9 +/- 135.5 MUmol/L) and maltodextrin (iAUC0-5h: -106.9 +/ 89.4 MUmol/L) and induced a smaller postprandial triacylglycerol response than whey protein (iAUC0-8h: -1.68 +/- 0.6 mmol/L). Milk proteins co-ingestion with high-fat meals may have the potential to maintain or improve CVD risk factors.

PMID- 29568005 TI - Possible bite-induced abscess and osteomyelitis in Lufengosaurus (Dinosauria: sauropodomorph) from the Lower Jurassic of the Yimen Basin, China. AB - We report an osseous abnormality on a specimen of the sauropod dinosaur Lufengosaurus huenei from the Fengjiahe Formation in Yuxi Basin, China. A gross pathological defect occurs on the right third rib, which was subjected to micro computed tomographic imaging as an aid in diagnosis. The analysis of pathological characteristics and the shape of the abnormality is incompatible with impact or healed trauma, such as a common rib fracture, and instead suggests focal penetration of the rib, possibly due to a failed predator attack. The identification of characteristics based on gross morphology and internal micro morphology presented by the specimen, suggests an abscess with osteomyelitis as the most parsimonious explanation. Osteomyelitis is a severe infection originating in the bone marrow, usually resulting from the introduction of pyogenic (pus-producing) bacteria into the bone. Micro-tomographic imaging of the lesion suggests a degree of healing and bone remodelling following post-traumatic wound infection with evidence of sclerotic bone formation at the site of pathological focus, indicating that L. huenei survived the initial trauma. However, as osteomyelitis can express through widespread systemic effects, including a lowering of immune response and overall condition, this disease may have been a contributing factor to the eventual death of the individual. PMID- 29568006 TI - Abrupt Climate Change in an Oscillating World. AB - The notion that small changes can have large consequences in the climate or ecosystems has become popular as the concept of tipping points. Typically, tipping points are thought to arise from a loss of stability of an equilibrium when external conditions are slowly varied. However, this appealingly simple view puts us on the wrong foot for understanding a range of abrupt transitions in the climate or ecosystems because complex environmental systems are never in equilibrium. In particular, they are forced by diurnal variations, the seasons, Milankovitch cycles and internal climate oscillations. Here we show how abrupt and sometimes even irreversible change may be evoked by even small shifts in the amplitude or time scale of such environmental oscillations. By using model simulations and reconciling evidence from previous studies we illustrate how these phenomena can be relevant for ecosystems and elements of the climate system including terrestrial ecosystems, Arctic sea ice and monsoons. Although the systems we address are very different and span a broad range of time scales, the phenomena can be understood in a common framework that can help clarify and unify the interpretation of abrupt shifts in the Earth system.

PMID- 29568008 TI - Voriconazole-induced photocarcinogenesis is promoted by aryl hydrocarbon receptor dependent COX-2 upregulation. AB - Voriconazole (VRCZ) induces the development of UV-associated skin cancers. The mechanism underlying the VRCZ-induced carcinogenesis has been largely unknown. Here, we showed that VRCZ metabolites plus UVA generated reactive oxygen species and resultant DNA damage of the epidermis, but did not induce substantial apoptosis in human keratinocytes (KCs). Furthermore, VRCZ per se stimulates aryl hydrocarbon receptor (AhR) and upregulates COX-2, which is a pivotal enzyme for the promotion of UV-associated tumors, in an AhR-ARNT dependent manner of the classical (genomic) pathway. Our findings suggest that the phototoxic moieties of VRCZ metabolites may participate in the initiation phase of VRCZ skin cancer, while VRCZ per se promotes the tumor development. Therefore, during VRCZ therapy, sun exposure protection is essential to prevent photocarcinogenesis caused by VRCZ metabolites plus UV. Chemoprevention with selective COX-2 inhibitors may be helpful to repress the development of skin cancers derived from DNA-damaged KCs. PMID- 29568009 TI - Low ocean-floor rises regulate subpolar sea surface temperature by forming baroclinic jets. AB - Sea surface temperature (SST) fronts in mid- to high-latitude oceans have significant impacts on extratropical atmospheric circulations and climate. In the western subarctic Pacific, sharp SST fronts form between the cold subarctic water and the recently found quasi-stationary jets that advect warm waters originating in the Kuroshio northeastward. Here we present a new mechanism of the jet formation paying attention to the propagation of baroclinic Rossby waves that is deflected by eddy-driven barotropic flows over bottom rises, although their height is low (~500 m) compared with the depth of the North Pacific Ocean (~6000 m). Steered by the barotropic flows, Rossby waves bring a thicker upper layer from the subtropical gyre and a thinner upper layer from the subarctic gyre, thereby creating a thickness jump, hence a surface jet, where they converge. This study reveals an overlooked role of low-rise bottom topography in regulating SST anomalies in subpolar oceans. PMID- 29568010 TI - A Poroelastic Model of a Fibrous-Porous Tissue Engineering Scaffold. AB - Tissue engineering scaffolds are used in conjunction with stem cells for the treatment of various diseases. A number of factors provided by the scaffolds affect the differentiation of stem cells. Mechanical cues that are part of the natural cellular microenvironment can both accelerate the differentiation toward particular cell lineages or induce differentiation to an alternative cell fate. Among such factors, there are externally applied strains and mechanical (stiffness and relaxation time) properties of the extracellular matrix. Here, the mechanics of a fibrous-porous scaffold is studied by applying a coordinated modeling and experimental approach. A force relaxation experiment is used, and a poroelastic model associates the relaxation process with the fluid diffusion through the fibrous matrix. The model parameters, including the stiffness moduli in the directions along and across the fibers as well as fluid diffusion time, are estimated by fitting the experimental data. The time course of the applied force is then predicted for different rates of loading and scaffold porosities. The proposed approach can help in a reduction of the technological and experimental efforts to produce 3-D scaffolds for regenerative medicine as well as in a higher accuracy of the estimation of the local factors sensed by stem cells. PMID- 29568011 TI - Inhibitory effect of surface pre-reacted glass-ionomer (S-PRG) eluate against adhesion and colonization by Streptococcus mutans. AB - Surface Pre-reacted Glass-ionomer (S-PRG) filler is a bioactive filler produced by PRG technology, which has been applied to various dental materials. A S-PRG filler can release multiple ions from a glass-ionomer phase formed in the filler. In the present study, detailed inhibitory effects induced by S-PRG eluate (prepared with S-PRG filler) against Streptococcus mutans, a major pathogen of dental caries, were investigated. S-PRG eluate effectively inhibited S. mutans growth especially in the bacterium before the logarithmic growth phase. Microarray analysis was performed to identify changes in S. mutans gene expression in the presence of the S-PRG eluate. The S-PRG eluate prominently downregulated operons related to S. mutans sugar metabolism, such as the pdh operon encoding the pyruvate dehydrogenase complex and the glg operon encoding a putative glycogen synthase. The S-PRG eluate inhibited several in vitro properties of S. mutans relative to the development of dental caries especially prior to active growth. These results suggest that the S-PRG eluate may effectively inhibit the bacterial growth of S. mutans following downregulation of operons involved in sugar metabolism resulting in attenuation of the cariogenicity of S. mutans, especially before the active growth phase. PMID- 29568012 TI - Modulation of the Neuregulin 1/ErbB system after skeletal muscle denervation and reinnervation. AB - Neuregulin 1 (NRG1) is a growth factor produced by both peripheral nerves and skeletal muscle. In muscle, it regulates neuromuscular junction gene expression, acetylcholine receptor number, muscle homeostasis and satellite cell survival. NRG1 signalling is mediated by the tyrosine kinase receptors ErbB3 and ErbB4 and their co-receptors ErbB1 and ErbB2. The NRG1/ErbB system is well studied in nerve tissue after injury, but little is known about this system in skeletal muscle after denervation/reinnervation processes. Here, we performed a detailed time course expression analysis of several NRG1 isoforms and ErbB receptors in the rat superficial digitorum flexor muscle after three types of median nerve injuries of different severities. We found that ErbB receptor expression was correlated with the innervated state of the muscle, with upregulation of ErbB2 clearly associated with the denervation state. Interestingly, the NRG1 isoforms were differently regulated depending on the nerve injury type, leading to the hypothesis that both the NRG1alpha and NRG1beta isoforms play a key role in the muscle reaction to injury. Indeed, in vitro experiments with C2C12 atrophic myotubes revealed that both NRG1alpha and NRG1beta treatment influences the best-known atrophic pathways, suggesting that NRG1 might play an anti-atrophic role.

AB - Data sourcesThe Cochrane Oral Health's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, the US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform databases.Study selectionRandomised controlled trials (cluster or parallel) evaluating school dental screening compared with no intervention or with one type of screening compared with another were included.Data extraction and synthesisTwo reviewers independently abstracted data and assessed risk of bias. Risk ratios were calculated for dichotomous outcomes, with data being pooled where appropriate. The GRADE approach was used to interpret findings.ResultsSix trials involving 19,498 children were included. Two were considered to be at low risk of bias, three at unclear risk and one at high risk. No conclusions could be made from four studies comparing traditional screening versus no screening because the evidence was inconsistent. Two trials evaluating criteria-based screening versus no screening suggested a possible benefit; RR = 1.07 (95% CI; 0.99-1.16). No difference was found when comparing criteria-based screening with traditional screening, RR = 1.01, (95% CI; 0.94-1.08). No trials reported on long-term follow up or cost-effectiveness and adverse events.ConclusionsThe trials included in this review evaluated short-term effects of screening, assessing follow-up periods of three to eight months. We found very low certainty evidence that was insufficient to allow us to draw conclusions about whether there is a role for traditional school dental screening in improving dental attendance. For criteria based screening, we found low-certainty evidence that it may improve dental attendance when compared to no screening. However, when compared to traditional screening there was no evidence of a difference in dental attendance (very low certainty evidence).We found low-certainty evidence to conclude that personalised or specific referral letters improve dental attendance when compared to non specific counterparts. We also found low-certainty evidence that screening supplemented with motivation (oral health education and offer of free treatment) improves dental attendance in comparison to screening alone.We did not find any trials addressing cost-effectiveness and adverse effects of school dental screening. PMID- 29568013 TI - Dual binding in cohesin-dockerin complexes: the energy landscape and the role of short, terminal segments of the dockerin module. AB - The assembly of the polysaccharide degradating cellulosome machinery is mediated by tight binding between cohesin and dockerin domains. We have used an empirical model known as FoldX as well as molecular mechanics methods to determine the free energy of binding between a cohesin and a dockerin from Clostridium thermocellum in two possible modes that differ by an approximately 180 degrees rotation. Our studies suggest that the full-length wild-type complex exhibits dual binding at room temperature, i.e., the two modes of binding have comparable probabilities at equilibrium. The ability to bind in the two modes persists at elevated temperatures. However, single-point mutations or truncations of terminal segments in the dockerin result in shifting the equilibrium towards one of the binding modes. Our molecular dynamics simulations of mechanical stretching of the full length wild-type cohesin-dockerin complex indicate that each mode of binding leads to two kinds of stretching pathways, which may be mistakenly taken as evidence of dual binding. PMID- 29568015 TI - Single dose oral prednisolone and post-operative endodontic pain. AB - DesignA randomised, single centre, double blind placebo controlled clinical trial involving 400 patients.InterventionThe inclusion criteria comprised systemically healthy patients between the ages of 18 and 35 years having mandibular molars with symptomatic irreversible pulpitis, radiographically normal periapical area and no pain on biting or percussion. The study was approved by the Institutional Review Board of Ethics Committee at the School of Dentistry, Cairo University, Egypt. Patients were recruited from the outpatient clinic of the Department of Endodontics.The independent Centre for Evidence Based Dentistry performed sequence generation and allocation concealment. For allocation concealment, two tablets of each medication were placed in sequentially numbered, opaque, sealed containers. Participants and operators were unaware of the assigned group for the duration of the study. Post-graduate students were calibrated to act as operators and supervisors from the department of endodontics evaluated their clinical performance.The participants received 40 mg of prednisolone or placebo tablets 30 minutes before single visit root canal treatment. Patients recorded the pain level 6, 12 and 24 hours after treatment on a 100mm visual analogue scale. All patients received a sham capsule to take if needed as a postoperative analgesic. If pain persisted an analgesic was prescribed.Outcome measureThe primary outcome was the incidence of postoperative pain at three points; 6, 12 and 24 hrs. The secondary outcomes were pain intensity and the incidence of analgesic consumption. The relative risk reduction (RRR) and the number needed-to-treat (NNT) and their 95% confidence intervals (CI) were used to represent the risk of pain incidence.ResultsOf the 670 patients assessed for eligibility, 400 were included in the study. Only two patients of the 400 were lost to follow-up with 398 patients (prednisolone group = 198; control group = 200) being included in the analysis; 259 were women and 141 men. The mean age was 29.45 -/+ 3.7 years in the prednisolone group and 28.97 -/+3.61 years in the control group. There was no significant difference for mean age (P = 0.164), gender distribution P = 0.123) or tooth type (P = 0.56) between the two groups. The relative risk reduction in pain incidence was 20.31% (95% CI: 12.03%, 27.82%) at six hours, 23.39% (95% CI: 14.75%, 31.16%) at 12 hours and 28.85% (95% CI: 18.08%, 38.20%) at 24 hours. Prednisolone had significantly less post-obturation pain intensity compared to placebo at 6, 12 and 24 hours (P < 0.001). The relative risk reduction in sham capsule intake was 54% (95% CI: 38%, 66%) and in analgesic intake was 55% (95% CI: 3%, 79%). No adverse effects were recorded. The NNT (number needed to treat) was five (95% CI: 4, 9) at six hours, five (95% CI: 4, 8) at 12 hours and four at 24 hours (95% CI: 3, 7).ConclusionsPreoperative oral administration of a single dose of 40 mg prednisolone was beneficial for the control of postoperative pain up to 24hrs after single visit root canal treatment in patients with symptomatic irreversible pulpitis. The incidence of postoperative pain level and the need for postoperative analgesic intake decreased. The non-invasive route and minimal possible adverse events results in a favourable risk benefit-balance. PMID- 29568016 TI - Too many reviews too few trials. PMID- 29568017 TI - The use of chlorhexidine in the prevention of alveolar osteitis after third molar extractions. AB - Data sourcesCochrane Central Register of Controlled Trials (CENTRAL), Medline through PubMed, Scopus, Science Direct, ISI Web of Science, Evidence-Based Dentistry, ClinicalTrials.gov, the European Union Clinical Trials Register, the Spanish General University Board database of doctoral theses in Spain (TESEO), the Spanish National Research Council (CSIC) bibliographic databases, and the Spanish Medical Index (IME).Study selectionRandomised controlled trials (RCTs) (with or without placebo) of patients of any age or gender who underwent maxillary or mandibular third molar extractions. Studies were required to have analysed the efficacy of only chlorhexidine in any concentration, formulation or treatment regimen for preventing alveolar osteitis (AO). There was no language restriction.Data extraction and synthesisData extraction was carried out independently by two researchers, and a third researcher was consulted in case of disagreements. When explicit data were not stated in the text, they were calculated using data from the tables where possible. In addition, authors were contacted to obtain any necessary missing information. Datasets were assessed for heterogeneity, and meta-analysis was conducted on homogenous datasets. Publication bias was assessed through funnel plots. The research was conducted and is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.ResultsTwenty-three studies published from 1979 to 2015, corresponding to 18 trials (16 parallel-group and two split-mouth RCTs), that reported on 2,824 third molar extractions (1,458 in experimental group and 1,366 in control group) were included. The overall relative risk (RR) was 0.53 (95% CI, 0.45-0.62; P<.0001). There was evidence of low heterogeneity (I2 = 9.3%; P = 0.336 by X2 test). The number needed to treat was eight (95% CI, 7-11). There were no differences between chlorhexidine rinse (RR = 0.58; 95% CI, 0.47-0.71) and gel (RR = 0.47; 95% CI, 0.37-0.60) for the prevention of AO after third molar extractions. Chlorhexidine did not cause more adverse reactions than placebo.ConclusionsThe use of chlorhexidine, in any formulation (rinse or gel), concentration (0.12% or 0.20%), or regimen (before, during and/or after surgery), is efficacious and effective in preventing AO in patients who have undergone third molar extraction. The findings showed that in order to prevent one case of AO, eight patients would have to be treated with chlorhexidine. Chlorhexidine gel was found to be moderately more efficacious than the rinse formulation. PMID- 29568018 TI - Cone-beam computed tomography or conventional radiography for localising of maxillary impacted canines? AB - Data sourcesPubMed, Web of Science, CINHAL and the Cochrane Library were searched until May 2016. Unpublished data were searched in Pro-Quest Dissertation, Abstracts and Thesis and Google Scholar, supplemented with manual search of the included studies references. No language restriction was used.Study selectionAll types of study designs were included, except case reports, comparing CBCT data with conventional radiographs. The primary outcome was: diagnostic accuracy between modalities, agreement in position, treatment planning and outcome efficacy. The secondary outcome was intermodality agreement in lateral root resorption detection and intra and inter-observer agreement values.Data extraction and synthesisTwo reviewers independently selected the studies for inclusion, performed data extraction and evaluated risk of bias. Discrepancies were resolved by discussions and reaching consensus. The Newcastle-Ottawa Scale was used to assess the risk of bias for case-controlled and cohort studies and a modified version for cross-sectional studies. The Quality Assessment of Diagnostic Accuracy (QUADAS-2) tool was used to rate diagnostic accuracy studies.ResultsEight studies met the inclusion criteria, two on diagnostic accuracy. The remaining six included 292 impacted canines in 224 patients. Outcomes were presented as calculated level of agreement and statistical significance for each primary outcome reported. Based on the diagnostic accuracy of two in vitro studies, the CBCT accuracy ranged from 50% to 95% while for conventional radiographs it ranged from 39% to 85%.The other six studies reported inter-modalities agreement in localisation (six studies) and treatment planning agreement (three studies). The inter-modalities agreement varied from 0.20 to 0.82, with observed agreement of 64% to 84% in localisation of canine. The treatment planning agreement varied from 0.36 to 0.72.ConclusionsThe authors concluded that CBCT is more accurate than conventional radiographs in localising maxillary impacted canines and there is a broad range of inter-observer and modalities agreement for location and treatment planning. There is no robust evidence to support using CBCT as first line imaging method.

However, they differed in participant ages and caries risk as well as toothpaste fluoride concentration. Outcomes and outcome measures also varied. Two trials reported statistically significant differences in favour of supervised toothbrushing but lacked data on effect size and precision. No meta-analyses were carried out because of the high degree of heterogeneity between the studies.ConclusionsThe lack of high quality evidence meant that this systematic review was unable to reach a definitive conclusion on the effectiveness of supervised toothbrushing programmes on caries incidence in children and adolescents.

AB - Data sourcesCochrane Oral Health and Pregnancy and Childbirth's Trial Registries, Cochrane Register of Controlled Trials, Cochrane Library, Medline Ovid, Embase Ovid and LILACS BIREME, clinicaltrials.com and the WHO Clinical Trials Registry Platform were searched for published and ongoing trials until October of 2016.Study selectionRandomised controlled trials (RCTs) investigating the effects of periodontal treatment in reducing or preventing perinatal and maternal morbidity and mortality with no exclusions of language or date of publication. Primary perinatal outcomes included: gestational age at birth, birth weight, small for gestational age and perinatal mortality, while the primary maternal outcomes included mortality, pre-eclampsia and treatment adverse effects.Data extraction and synthesisTwo authors independently screened for inclusion and extracted data. Risk of bias was assessed using the Cochrane 'risk of bias' tool.Dichotomous results were expressed as risk ratios (RR) with a 95% confidence interval (CI), and continuous data were expressed as mean differences (MD) with 95% confidence interval. Random-effects model was used for combining results.The quality of the evidence was assessed using GRADE.ResultsFifteen studies with a total of 7,161 participants met the inclusion criteria.Eleven studies (n = 5671) compared periodontal treatment with no treatment. For the outcome preterm birth before <37 weeks a calculated RR of 0.87, 95% CI 0.70-1.10 shows no clear difference. From seven studies (n = 3470) there is evidence that periodontal treatment may reduce birth weight <2500g (RR 0.77, 95% CI 0.48-0.95).There is unclear evidence on the effect of periodontal treatment on preterm birth <35 weeks, <32 weeks, perinatal mortality and pre-eclampsia.Three studies with 3,610 participants showed no evidence of difference in the outcome small for gestational age: RR 0.97, 95% CI 0.81-1.16.ConclusionsThere is no clear evidence that periodontal treatment during pregnancy has an effect on preterm birth. There is some evidence that it may reduce incidence of low birth weight.There is insufficient evidence to define what type of periodontal treatment is superior in preventing any adverse pregnancy outcome. PMID- 29568021 TI - Insufficient evidence to support or reject effect of conservative TMD therapies on otologic signs and symptoms. AB - Data sourcesThe search strategy focused on publications up to May 2015 in five electronic databases: PubMed, LILACS, Scopus, Web of Science and Science Direct. Furthermore, a partial grey literature search through Google Scholar and a hand search of the references of the included studies were also performed.Study selectionThose studies including patients with TMD associated with otologic signs and symptoms treated with conservative therapies, such as physiotherapy or cognitive behavioural therapy. These studies needed to describe whether the conservative treatments affected the associated otologic signs and symptoms. No language or time restrictions were applied.Data extraction and synthesisThe search was completed in two stages. 1st stage: titles and abstracts were screened and included (or excluded) independently by two reviewers. 2nd stage: the same selection criteria were applied to the full text of the previously selected studies by the same reviewers. Disagreements were discussed, and a third author was involved, when required, to make a final decision. Study quality was assessed by the two reviewers using two risk of bias tools: 'Quality Assessment of a Cohort Study' and 'Quality Assessment of a Randomised Clinical Trial'. Because of heterogeneity in the study designs only a narrative summary was presented.ResultsEight studies were finally included in this review. Three of them were randomised clinical trials and five were cohort studies. All studies had an acceptable risk of bias, except one with high risk of bias. Seven of the eight studies showed total or partial resolution of otologic signs and/or symptoms after TMD therapy.ConclusionsInsufficient evidence was identified to strongly support positive or negative changes in otologic signs and symptoms after conservative management therapies for TMD. Further studies with a higher level of evidence and more representative samples should be conducted to improve our understanding of the effect of TMD therapy on otologic complains. PMID- 29568023 TI - Which surgical approach for palatally displaced canines? AB - Data sourcesCochrane Oral Health's Trials Register, Cochrane Central Register of Controlled Trials, Medline Ovid and Embase Ovid (up to February 2017); ongoing clinical trials were searched in clinicaltrials.gov as well as the World Health Organization International Clinical Trials Registry. Reference lists of included studies and relevant systematic reviews were searched. No restrictions were placed on the language or date of publication and study authors were contacted when necessary.Study selectionRandomised and quasi-randomised controlled trials assessing open and closed surgical exposures in palatally displaced canines with no restriction on age, presenting malocclusion or type of orthodontic treatment. Unilaterally and bilaterally displaced canines were included in the review. The primary outcomes considered were sufficient eruption of the canine to allow orthodontic alignment without requiring additional surgery, post surgical complications and aesthetics.Data extraction and synthesisTwo authors independently screened titles and abstracts of all studies identified through the search and reviewed full articles against established inclusion criteria. Any disagreements between the authors were resolved by consensus or by consulting an expert. Risk of bias assessment was done using Cochrane Collaboration's tool and study authors were contacted for missing information. Dichotomous outcomes (success of surgery - yes or no) were expressed as risk ratio and 95% CI. Continuous outcomes (pain on VAS scale) were expressed as mean differences (MD) or standardised mean differences (if different scales were used).ResultsA total of three studies (six articles) representing 146 participants were included in the SR. One was an RCT while the other two were quasi-RCTs. With regards to successful eruption, there was no evidence of a difference between the open and closed groups (RR 0.99, 95% CI 0.93-1.06, P = 0.79). Other primary measures (including surgical complications or aesthetics) or secondary measures were either reported in just one trial or used different measures, so pooling of data was not possible.ConclusionsLimited available evidence suggests surgical exposure of palatally displaced canines is successful in bringing canines into alignment. However, data do not support one technique over the other (closed vs open). One trial was at low risk of bias while the others were at high risk of bias. This adds to the uncertainty of the conclusions. PMID- 29568024 TI - Is there an association between maternal smoking and oral clefts? AB - Data sourcesCochrane, PubMed and Ovid Medline. A search timeline of January 1966 to May 2015 was used and language was restricted to English.Study selectionCase control and cohort studies relating to oral clefts, with information on maternal active smoking, before and after conception, excluding paternal smoking and exposure to environmental tobacco smoke.Data extraction and synthesisTwo authors extracted data independently. Both Begg's and Egger's funnel plots were used to assess publication bias. Sensitivity analysis was performed to assess impact of the different study types and chi-squared and P values were determined by SPSS software. Studies with missing data were excluded from the meta-analysis.ResultsA statistically significant association was found between maternal active smoking and CL +/- P (odds ratio [OR] 1.368; 95% confidence interval [CI] 1.259-1.486) as well as CP (OR 1.241; 95% CI 1.117-1.378). Half the studies showed positive dose response effect for each subgroup (test for linear trend, P < .05).ConclusionsWomen who smoke during pregnancy have a moderate risk of having a child with a CL +/- P or CP. A dose-response effect between maternal smoking and clefts was not established. PMID- 29568025 TI - Are pharmacological treatments for oro-facial pain effective? AB - Data sourcesElectronic searches of PubMed, the Cochrane Library, Embase, the National Health Service Economic Evaluation Database and HTA until March 2017. Also handsearched referenced in the original articles. Grey literature was not included.Study selectionRandomised controlled trials with more than ten participants with oro-facial pain duration of more than three months were sub grouped into: TMD-muscle pain (TMD-m), TMD-joint pain (TMD-j), burning mouth syndrome (BMS) and other oro-facial pain. Studies include any pharmacological treatment against another pharmacological, non-pharmacological treatment, placebo or no treatment. The primary outcome was change in pain intensity and the secondary outcome was the effect on quality of life.Data extraction and synthesisThree authors formed three review pairs that independently checked for inclusion. Four pairs of reviewers independently evaluated the risk of bias using the Swedish Agency for Health Technology Assessment and Assessment of Social Services tool. Two authors independently extracted data that were later assessed according to a modified GRADE system.ResultsForty-one studies, rated medium to low risk of bias, were included in qualitative analysis on patients with TMD-j pain (15 studies, n = 790), TMD-m pain (nine studies, n = 375), BMS (17 studies n = 868). For the TMD-j group five studies support NSAIDs and nine corticosteroid and hyaluronate injections. Eight of the nine TMD-m studies were included in a network meta-analysis (NMA), they support cyclobenzaprine, botulinum toxin injections and topical treatment with Ping-On ointment. Five of the 17 BMS studies included in a NMA support topical capsaicin and clonazepam. Of the remaining 12, five showed no effect while the remaining support alpha lipoic acid, gabapentin, clonazepam, amisulpride and SSRIs.ConclusionsBased on the results of the NMA the authors concluded that clonazepam and capsaicin are effective for BMS while cyclobenzaprine, a muscle relaxant, has a positive treatment effect on TMJ-m. Evidence from the narrative synthesis suggests NSAIDs, corticosteroid and hyaluronate injections are effective for TMD-j pain. PMID- 29568026 TI - Insufficient evidence for interventions to prevent dry mouth and salivary gland dysfunction post head and neck radiotherapy. AB - Data sourcesCochrane Oral Health's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, CINAHL, EBSCO (Cumulative Index to Nursing and Allied Health Literature, LILACS, BIREME, Virtual Health Library (Latin American and Caribbean Health Science Information database), Zetoc Conference Proceedings, the US National Institutes of Health Ongoing Trials Register, (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases.Study selectionThe review included randomised controlled trials, irrespective of their language of publication or publication status. Participants could be outpatients or inpatients. The review included trials comparing any pharmacological agent regimen, prescribed prophylactically for salivary gland dysfunction prior to or during radiotherapy, with placebo, no intervention or an alternative pharmacological intervention. Comparisons of radiation techniques were excluded.Data extraction and synthesisStandard Cochrane methodological processes were followed.ResultsThirty-nine studies that randomised 3520 participants were included; the number of participants analysed varied by outcome and time point. The studies were ordered into 14 separate comparisons with meta analysis only being possible in three of those. We found low quality evidence to show that amifostine, when compared to a placebo or no treatment control, might reduce the risk of moderate to severe xerostomia (grade 2 or higher on a 0 to 4 scale) at the end of radiotherapy (risk ratio (RR) 0.35, 95% confidence interval (CI) 0.19 to 0.67; P = 0.001, three studies, 119 participants), and up to three months after radiotherapy (RR 0.66, 95% CI 0.48 to 0.92; P = 0.01, five studies, 687 participants), but there is insufficient evidence that the effect is sustained up to 12 months after radiotherapy (RR 0.70, 95% CI 0.40 to 1.23; P = 0.21, seven studies, 682 participants). We found very low quality evidence that amifostine increased unstimulated salivary flow rate up to 12 months after radiotherapy, both in terms of mg of saliva per five minutes (mean difference (MD) 0.32, 95% CI 0.09 to 0.55; P = 0.006, one study, 27 participants), and incidence of producing greater than 0.1 g of saliva over five minutes (RR 1.45, 95%CI 1.13 to 1.86; P = 0.004, one study, 175 participants).However, there was insufficient evidence to show a difference when looking at stimulated salivary flow rates. There was insufficient (very low quality) evidence to show that amifostine compromised the effects of cancer treatment when looking at survival measures. There was some very low quality evidence of a small benefit for amifostine in terms of quality of life (ten-point scale) at 12 months after radiotherapy (MD 0.70, 95% CI 0.20 to 1.20; P = 0.006, one study, 180 participants), but insufficient evidence at the end of and up to three-month post radiotherapy. A further study showed no evidence of a difference at 6, 12, 18 and 24-month post radiotherapy.There was low quality evidence that amifostine is associated with increases in: vomiting (RR 4.90, 95% CI 2.87 to 8.38; P < 0.00001, five studies, 601 participants); hypotension (RR 9.20, 95% CI 2.84 to 29.83; P = 0.0002, three studies, 376 participants); nausea (RR 2.60, 95% CI 1.81 to 3.74; P < 0.00001, four studies, 556 participants); and allergic response (RR 7.51, 95% CI 1.40 to 40.39; P = 0.02, three studies, 524 participants).The authors founded insufficient evidence (that was of very low quality) to determine whether or not pilocarpine performed better or worse than a placebo or no treatment control for the outcomes: xerostomia, salivary flow rate, survival and quality of life. There was some low quality evidence that pilocarpine was associated with an increase in sweating (RR 2.98, 95% CI 1.43 to 6.22; P = 0.004, five studies, 389 participants).The authors found insufficient evidence to determine whether or not palifermin performed better or worse than placebo for: xerostomia (low quality); survival (moderate quality); and any adverse effects. There was also insufficient evidence to determine the effects of the following interventions: biperiden plus pilocarpine, Chinese medicines, bethanechol, artificial saliva, selenium, antiseptic mouthrinse, antimicrobial lozenge, polaprezinc, azulene rinse and Venalot Depot (coumarin plus troxerutin).ConclusionsThere is some low quality evidence to suggest that amifostine prevents the feeling of dry mouth in people receiving radiotherapy to the head and neck (with or without chemotherapy) in the short- (end of radiotherapy) to medium-term (three-month post radiotherapy). However, it is less clear whether or not this effect is sustained to 12-month post radiotherapy. The benefits of amifostine should be weighed against its high cost and side effects. There was insufficient evidence to show that any other intervention is beneficial. PMID- 29568027 TI - Chlorhexidine gel to prevent alveolar osteitis following mandibular third molar extractions. AB - Data sourcesMedline/PubMed, Cochrane central, Scopus and Google scholar.Study selectionRandomised controlled trials (RCTs) published in English between January 2010 and December 2015 were identified by two reviewers. Unpublished studies were not considered.Data extraction and synthesisStandard Cochrane Collaboration assessment tools were used to carry out a risk of bias assessment. The following data were collected from the articles; sample size, country, mean age of participants, diagnosis of alveolar osteitis (AO), type of intervention and outcomes. Heterogeneity (I2) was calculated to determine the statistical model to be used for meta-analysis.ResultsTen randomised control trials (RCTs) were included, with 862 participants. Eight studies used 0.2% chlorhexidine (CHX) gel in the experimental group, 1% CHX gel in one study, and in one study the concentration was not specified. Two studies used adjunctive antibiotics, and one study gave 400mg Ibuprofen to all participants.Six of the RCTs were at low risk of bias, three studies showed possible selection and/or performance bias, and one study gave no information on bias. Heterogeneity was low level (I2 = 40%) and a funnel plot presented a low level of publication bias.The included RCTs used Blum's criteria for diagnosis of AO. Six of the RCTs were conducted double blinded. The risk ratio (RR) was calculated for each RCT and also for the pooled effect. The overall pooled effect of CHX gel placed in the extraction socket following mandibular 3rd molar removal was calculated to have prevented 57% of AO instances (RR = 0.43, 95% CI: 0.32, 0.58; p<0.00001). Subgroup analysis of the effect of CHX gel in participants who smoked/used the oral contraceptive pill (OCP) was calculated to have prevented 40% of AO (RR = 0.60, 95% CI: 0.41, 0.87; p = 0.007). In the studies that used a split-mouth design, CHX gel prevented 71% of AO incidence (RR = 0.29, 95% CI: 0.16, 0.50; p <0.0001).ConclusionsThis meta analysis and systematic review concluded 'clinically significant evidence that CHX gel application in the extraction socket of mandibular 3rd molar has reduced the incidence of alveolar osteitis'. PMID- 29568028 TI - Breastfeeding and occlusal development. AB - Data sourcesPubmed, Embase, Scopus databases and New York Academy of Medicine Grey Literature Report. There were no restrictions on language and publication dates.Study selectionTwo reviewers selected both prospective and retrospective studies of children who had either been exclusively breastfed or were mixed breastfed; who were in either the primary or mixed dentition, and malocclusion was assessed. The following malocclusion traits were included; Class 2 molar, open-bite, non-spaced dentition and posterior crossbite.Data extraction and synthesisData were extracted including type of dentition, type of malocclusion, breastfeeding data collection method, results, breast feeding malocclusion odds ratio (OR) and quality of the article. The ORs of associations between different lengths of breastfeeding and the various malocclusion traits were calculated.ResultsThirty-one studies were included in a qualitative synthesis, nine in the quantitative analysis. All studies were observational, a majority examining malocclusion in the mixed dentition. Two studies looked at associations between no breastfeeding and posterior crossbite, finding children not breastfed presented 1.7 times more posterior crossbite than those breastfed for between one and six months (OR = 1.70 CI 2.01-2.39). ORs were calculated for exclusive breastfeeding and posterior crossbite with different duration of breastfeeding, and duration of breastfeeding and posterior crossbite. With regard to open bite and breastfeeding the OR=1.76 (CI 0.55-5.61) comparing those who were breastfed for less than or more than six months. Children breastfed for up to six months presented 1.25 times more Class 2 molar relationships than those breastfed for over six months. Children breastfed for up to six months presented 1.73 times more non-spaced dentitions than those breastfed for over six months (OR =1.73, CI 1.35-2.22).ConclusionsBreastfeeding is a protective factor against posterior crossbites and Class 2 malocclusion in primary and mixed dentitions, with the protective effect increasing with the months of breastfeeding. There is no clear evidence for breastfeeding proving any benefit against other malocclusion risks; open bite and non-spaced dentitions. PMID- 29568029 TI - Limited evidence on best material for retrograde root fillings. AB - Data sourcesCochrane Oral Health's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline Ovid, Embase Ovid, LILACS, BIREME Virtual Health Library, OpenSIGLE, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform, Chinese BioMedical Literature Database, VIP (in Chinese), China National Knowledge Infrastructure and Sciencepaper Online. No restrictions on language or date of publication were placed.Study selectionRandomised controlled trials (RCTs) that compared different retrograde filling materials, with clinical or radiological assessment for success over a minimum follow-up period of 12 months.Data extraction and synthesisTwo review authors extracted data independently and in duplicate, and subsequently carried out risk of bias assessment for each eligible study following Cochrane methodological guidelines. Original trial authors were contacted for any missing information.ResultsSix randomised controlled trials were included, with 916 participants involving 988 teeth. All these studies had a high risk of bias. Comparisons of five different retrograde filling materials were undertaken, including MTA versus intermediate restorative material (IRM), MTA versus super ethoxybenzoic acid cement (Super-EBA), Super-EBA versus IRM, dentine-bonded resin composite versus glass ionomer cement and glass ionomer cement versus amalgam.Grouping of data from different studies was minimal and provided limited evidence for each comparison. All studies showed a risk ratio of approximately one, indicating that there is weak or little evidence that any of the materials are superior. All of the studies displayed very low quality of evidence. None of these studies reported adverse events.ConclusionsCurrently there is insufficient evidence to determine which material is preferable for retrograde filling. Further high-quality RCTs are required for this. PMID- 29568030 TI - Periodontal disease has an impact on patients' quality of life. AB - Data sourcesMedline, Embase, OpenGrey, Journal of Clinical Periodontology, Journal of Periodontology and a hand search of the bibliographies of retrieved publications.Study selectionTwo reviewers screened the title and abstract of 1134 studies from the literature and selected 37 suitable publications for inclusion following full text analysis of 109 papers and agreement between both reviewers. The search included observational, epidemiological studies and clinical trials that fufilled the inclusion criteria. The publications assessed contained a periodontal clinical examination and a validated OHRQoL questionnaire. There were no language restrictions and the review was performed according to the MOOSE statement.Data extraction and synthesisData were extracted from each study applying the PECO format. The quality of the observational studies was evaluated by the Newcastle Ottawa Scale (NOS) and clinical trials by the (MINORS) methodological index for non-randomised studies. The Strength of Grading Taxonomy (SORT) was utilised to assess the level of evidence and strength of recommendation of the included studies. A meta-analysis was not undertaken due the heterogeneity of the included studies, therefore results were synthesised by applying a vote counting method.ResultsThirty-seven studies included in the review were evaluated by the vote counting method. According to NOS and MINORS the risk of bias was identified as moderate with most studies assessing 50% to 83% of the parameters established. A level two for quality of evidence and a level B for strength of recommendation were applicable for the relationship between clinically diagnosed periodontal disease and OHRQoL. The evidence level was consistent across the studies. Nineteen of the studies examined a distinct population group with respect to diagnosis of systemic disease, socioeconomic status, demographic background or periodontal diagnosis. Twenty-eight of the included studies reported an association between periodontal diseases and OHRQoL while eight of the publications highlighted a dose-response relationship between and extent and severity of periodontal disease and the impact on OHRQoL.ConclusionsThe findings support the association between clinically diagnosed periodontal diseases and subjectively assessed OHRQoL with a dose response relationship demonstrated. In summation, periodontal diseases play a significant role in oral health and impact on the QoL of affected individuals. In publications that undertook a full mouth recording the results were more evident, therefore a comprehensive periodontal exam in conjunction with a validated OHRQoL questionnaire is recommended.

PMID- 29568032 TI - Mesoproterozoic juvenile crust in microcontinents of the Central Asian Orogenic Belt: evidence from oxygen and hafnium isotopes in zircon. AB - We report in situ O and Hf isotope data of zircon grains from coeval Mesoproterozoic (ca. 1.4 Ga) igneous metamafic (amphibolite) and granitic rocks of the Chinese Central Tianshan microcontinent (CTM) in the southern Central Asian Orogenic Belt (CAOB). Zircon grains from amphibolite have mantle-like delta18OVSMOW values of 4.7-5.60/00 and juvenile Hf isotopic compositions (epsilonHf(t) = 8.4-15.3; TDMC = 1.57-1.22 Ga), whereas those from granitic rocks have delta18OVSMOW values of 5.6-7.00/00 and evolved Hf isotopic compositions (epsilonHf(t) = -1.0-8.2; TDMC = 2.09-1.62 Ga). Zircon O-Hf isotopic compositions of the metamafic and granitic rocks provide evidence for Mesoproterozoic (ca. 1.4 Ga) crustal growth and a substantial Palaeoproterozoic supracrustal component in the CTM. These findings and previous studies, reporting ca. 1.4 Ga magmatic rocks from other microcontinents of the CAOB, suggest that a large belt of Mesoproterozoic (ca. 1.4 Ga) juvenile continental crust formed in a continental terrane, fragments of which now occur over a distance of more than a thousand kilometres in the southern CAOB. PMID- 29568033 TI - Adsorption-based atmospheric water harvesting device for arid climates. AB - Water scarcity is a particularly severe challenge in arid and desert climates. While a substantial amount of water is present in the form of vapour in the atmosphere, harvesting this water by state-of-the-art dewing technology can be extremely energy intensive and impractical, particularly when the relative humidity (RH) is low (i.e., below ~40% RH). In contrast, atmospheric water generators that utilise sorbents enable capture of vapour at low RH conditions and can be driven by the abundant source of solar-thermal energy with higher efficiency. Here, we demonstrate an air-cooled sorbent-based atmospheric water harvesting device using the metal-organic framework (MOF)-801 [Zr6O4(OH)4(fumarate)6] operating in an exceptionally arid climate (10-40% RH) and sub-zero dew points (Tempe, Arizona, USA) with a thermal efficiency (solar input to water conversion) of ~14%. We predict that this device delivered over 0.25 L of water per kg of MOF for a single daily cycle. PMID- 29568034 TI - Author Correction: Deep sequencing reveals the first fabavirus infecting peach.

PMID- 29568035 TI - Integrating Free-Form Nanostructured GRIN Microlenses with Single-Mode Fibers for Optofluidic Systems. AB - We present both a theoretical and an experimental study of a novel compact lensed fiber system utilizing a nanostructured GRIN lens. The lens can be integrated with an optical fiber, which ensures a unique and efficient focusing in any high index medium, such as a liquid. We use the effective medium approach to design lenses with arbitrary refractive index. To fabricate lenses, we utilize a discrete array of nano-sized rods made of two types of glasses, and apply a standard stack-and-draw fiber drawing technology. The fabricated nanostructured GRIN lenses have a parabolic refractive index profile with a diameter of a standard fiber, very short working distances (55 um in the air) and a high numerical aperture (NA = 0.16). As a proof-of-concept of the new micro-lensed fiber system, we demonstrate an experiment on optical trapping of micrometer sized glass beads. We also show that our method is compatible with optical fiber technology and allows for any shape of the refractive index distribution in 2D. Thanks to that a new functionality could be achieved by replacing the GRIN lens with an axicon lens, vortex type elements, micro-lenses arrays or diffraction elements.

PMID- 29568037 TI - Interfacial Hydrolysis of Acetals on Protonated TEMPO-oxidized Cellulose Nanofibers. AB - 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TOCNs), which have a high-density of exposed carboxylic acid groups on their crystalline surfaces, effectively act as acid catalysts in acetal hydrolysis. Carboxy-free cellulose nanofibers, polymeric carboxylic acids, and homogeneous acetic acid do not show significant catalytic activity under the same reaction conditions. Mercerized TOCNs differing from the original TOCNs in a crystalline structure were also ineffective, which suggests that the unique nanoarchitectural features of TOCNs, such as regularly aligned carboxylic acid groups, large specific surface areas, and structural rigidity, must be major factors in the acceleration of acetal hydrolysis. Kinetic analysis suggested that substrates and/or acid catalyst species were concentrated on the TOCN crystalline surfaces, which significantly enhanced the catalytic activity. PMID- 29568038 TI - Frequency of Esophageal Eosinophilia in a Pediatric Population from Central Brazil. AB - Here we report a retrospective cross-sectional study on Esophageal eosinophilia (EsEo) frequency in Brazil, for 2, 425 pediatric patients with symptoms associated with gastroesophageal diseases in 2012. EsEo is defined by >=15 eosinophils per high power field (400x) and confirmed through histological analyses of esophageal biopsies. Overall, 126 patients had EsEo equating to a frequency of 5.2%. There was a significant difference between the endoscopic features of patients with EsEo, where 10.7% had erosive esophagitis, 3.0% had non erosive esophagitis and 1% showed normal esophageal mucosa. According to the interaction of the variables in the Classification and Regression Tree Analysis, most patients diagnosed with EsEo were older males with erosive esophagitis. On the other hand, the lowest frequency of EsEo was found among younger females with non-erosive esophagitis/normal mucosa. Environmental conditions, including climate variation and changes, were observed in association with EsEo, supporting a potential role for environmental factors in its pathogenesis. There was an inverse correlation between the number of EsEo, rainfall and humidity. EsEo is a relatively frequent finding in the pediatric population of Brazil with symptoms of gastroesophageal diseases. Both clinical and histological examinations of patients are important for a reliable diagnostic of EsEo cases and to patient care.

PMID- 29568040 TI - Drivers of solar radiation variability in the McMurdo Dry Valleys, Antarctica. AB - Annually averaged solar radiation in the McMurdo Dry Valleys, Antarctica has varied by over 20 W m-2 during the past three decades; however, the drivers of this variability are unknown. Because small differences in radiation are important to water availability and ecosystem functioning in polar deserts, determining the causes are important to predictions of future desert processes. We examine the potential drivers of solar variability and systematically eliminate all but stratospheric sulfur dioxide. We argue that increases in stratospheric sulfur dioxide increase stratospheric aerosol optical depth and decrease solar intensity. Because of the polar location of the McMurdo Dry Valleys (77-78 degrees S) and relatively long solar ray path through the stratosphere, terrestrial solar intensity is sensitive to small differences in stratospheric transmissivity. Important sources of sulfur dioxide include natural (wildfires and volcanic eruptions) and anthropogenic emission. PMID- 29568041 TI - Prior Expectation Modulates Repetition Suppression without Perceptual Awareness. AB - Stimulus repetition induces attenuated brain responses. This phenomenon, termed repetition suppression (RS), is classically held to stem from bottom-up neuronal adaptation. However, recent studies suggest that RS is driven by top-down predictive mechanisms. It remains controversial whether these top-down mechanisms of RS rely on conscious strategies, or if they represent a more fundamental aspect of perception, coding for physical properties of the repeated feature. The presence of top-down effects in the absence of perceptual awareness would indicate that conscious strategies are not sufficient to explain top-down mechanisms of RS. We combined an unconscious priming paradigm with EEG recordings and tested whether RS can be modulated by the probability of encountering a repetition, even in the absence of awareness. Our results show that both behavioural priming and RS near occipital areas are modulated by repetition probability, regardless of prime awareness. This contradicts previous findings that have argued that RS modulation is a by-product of conscious strategies. In contrast, we found that the increase in theta-band power following unrepeated trials - an index of conflict detection - is modulated only by expectations during conscious primes, implicating the use of conscious strategies. Together, our results suggest that the influence of predictions on RS can be either automatic in sensory brain regions or dependent on conscious strategies.

AB - The increasing prevalence of functional and motility gastrointestinal (GI) disorders is at odds with bottlenecks in their diagnosis, treatment, and follow up. Lack of noninvasive approaches means that only specialized centers can perform objective assessment procedures. Abnormal GI muscular activity, which is coordinated by electrical slow-waves, may play a key role in symptoms. As such, the electrogastrogram (EGG), a noninvasive means to continuously monitor gastric electrical activity, can be used to inform diagnoses over broader populations. However, it is seldom used due to technical issues: inconsistent results from single-channel measurements and signal artifacts that make interpretation difficult and limit prolonged monitoring. Here, we overcome these limitations with a wearable multi-channel system and artifact removal signal processing methods. Our approach yields an increase of 0.56 in the mean correlation coefficient between EGG and the clinical "gold standard", gastric manometry, across 11 subjects (p < 0.001). We also demonstrate this system's usage for ambulatory monitoring, which reveals myoelectric dynamics in response to meals akin to gastric emptying patterns and circadian-related oscillations. Our approach is noninvasive, easy to administer, and has promise to widen the scope of populations with GI disorders for which clinicians can screen patients, diagnose disorders, and refine treatments objectively.

AB - A novel blood-borne virus called the human hepegivirus 1 (HHpgV-1) was recently discovered in hemophilia patients. The present study aimed to investigate the presence of HHpgV-1 in hemophilia patients. A total of 436 serum samples were investigated for the presence of hepatitis C virus (HCV), human pegivirus-1 (HPgV 1), torque teno virus (TTV), and HHpgV-1. Out of the 436 patients, 163 (37.4%), 19 (4.4%), 76 (17.4%), and four (0.9%) patients were positive for HCV, HPgV-1, TTV, and HHpgV-1, respectively. HHpgV-1 patients had a mean viral load of 4.9 +/- 0.3 log RNA copies/mL and were co-infected with HCV-1a, HPgV-1, and TTV. Moreover, three HHpgV-1-positive patients exhibited stage F0 liver fibrosis. HCV viral load in HHpgV-1-positive patients was lower than those of HHpgV-1-negative patients. Results also revealed that co-infection of HHpgV-1 with HPgV-1 and HCV may play a protective role in patients with chronic HCV. In conclusion, we detected a low frequency of HHpgV-1 infection in hemophilia patients, and results suggested that HHpgV-1 infection was correlated with the presence of other blood borne viruses and is likely to also correlate with low HCV viral load and reduced severity of liver disease. Additional studies are required to further investigate the clinical importance of HHpgV-1. PMID- 29568044 TI - Multi-Target Tracking of Human Spermatozoa in Phase-Contrast Microscopy Image Sequences using a Hybrid Dynamic Bayesian Network. AB - Male infertility is mostly related to semen and spermatozoa, and any diagnosis or treatment requires the investigation of the motility patterns of spermatozoa. The movements of spermatozoa are fast and involve collision and occlusion with each other. In order to extract the motility patterns of spermatozoa, multi-target tracking (MTT) of spermatozoa is necessary. One of the most important steps of MTT is data association, in which the newly arrived observations are used to update the previous tracks. Dynamic Bayesian network (DBN) is a powerful tool for modeling and solving various types of problems such as tracking and classification. There can also be a hybrid-DBN (HDBN), in which both continuous and discrete nodes are present. HDBN has a suitable structure for modeling problems that have both discrete and continuous parameters like MTT. In this research, the data association for MTT of human spermatozoa has been studied. The proposed algorithm was tested over hundreds of manually extracted spermatozoa tracks and evaluated using several standard measures. The superior results of the proposed algorithm in comparison to the other well-known algorithms, show that it could be considered as an improved alternative to traditional computer assisted sperm analysis (CASA) algorithms.

AB - Here we report Sr and Zn isotope ratios of teeth of medieval to early modern Breton people a population whose diet is known from historical, archeological and collagen isotope data. Most of the population, buried in the Dominican convent of Rennes, France, consists of parliamentary nobles, wealthy commoners and ecclesiastics, who had a diet rich in animal products. Our aim is to assess how the Zn isotope ratios of their teeth compare to those of other French historical populations previously studied, which were characterized by cereal-based diets, and those of modern French individuals, who daily eat animal products. We describe a clear offset (~0.350/00) between local and non-local human individuals in Zn isotope ratios. The delta66Zntooth values of local individuals overlap that of modern French people, and are lower than those of local carnivores. Non-local delta66Zn values are similar to those of historical individuals analyzed previously. We conclude the lower Zn isotope ratios of local humans relative to the associated fauna can be explained by the consumption of carnivorous fish and pork, in agreement with historical, zooarchaeological and collagen (C, N, S) isotope data. Zn isotopes could therefore be a tracer of fish and/or substantial meat consumption in ancient populations.

AB - Aedes albopictus (Diptera: Culicidae) is an invasive mosquito, native to Asia, that has expanded its range worldwide. It is considered to be a public health threat as it is a competent vector of viruses of medical importance, including dengue, chikungunya, and Zika. Despite its medical importance there is almost no information on biologically important traits of Ae. albopictus in Argentina. We studied life cycle traits, demographic parameters and analyzed the competence of this mosquito as a virus vector. In addition, we determined the prevalence of Wolbachia strains in Ae. albopictus as a first approach to investigate the potential role of this bacteria in modulating vector competence for arboviruses. We observed low hatch rates of eggs, which led to a negative growth rate. We found that Ae. albopictus individuals were infected with Wolbachia in the F1 but while standard superinfection with wAlbA and wAlbB types was found in 66.7% of the females, 16.7% of the females and 62.5% of the males were single-infected with the wAlbB strain. Finally, despite high levels of infection and dissemination, particularly for chikungunya virus, Ae. albopictus from subtropical Argentina were found to be relatively inefficient vectors for transmission of both chikungunya and dengue viruses.

AB - A transparent semiconducting SrTiO3 single crystal with a resistivity of the order of 103 Omega.cm was fabricated by heating a SrTiO3 single crystal with gaseous ammonia and CeO2 powder. Conductive atomic force microscope (C-AFM) measurement revealed that micro-sized voids were formed and the high conductivity was exhibited only at around the voids. It is considered that the micro-sized voids were caused by the concentrated SrO planar defects, and TiO2-terminated structure with oxygen vacancies contributed to the two-dimensional conduction. In the heating process, the CeO2 powder acted as an oxygen source, and radicals such as NH2 and NH were generated by the reaction of oxygen and ammonia. The radicals may have contributed to the formation of three-dimensional network of the conductive paths consisting of SrO planar defects without the reduction of the bulk components. The electrons were localized on the TiO2-terminated structure, and the volume content of the conductive paths was small compared to the insulating bulk component. Therefore, the crystal was optically transparent and semiconducting. PMID- 29568048 TI - Electrospinning over Solvent Casting: Tuning of Mechanical Properties of Membranes. AB - We put forth our opinion regarding the enhanced plasticity and modulation of mechanical properties of polymeric films obtained through electrospinning process in this article. In majority of the pharmaceutical, biomedical, and packaging applications, it is desirable that polymer based matrices should be soft, flexible, and have a moderate toughness. In order to convert inflexible and brittle polymers, adjuvants in the form of plasticizers are added to improve the flexibility and smoothness of solvent casted polymer films. However, many of these plasticizers are under scrutiny for their toxic effects and environmental hazards. In addition, plasticizers also increase the cost of end products. This has motivated the scientific community to investigate alternate approaches. The changes imparted in membrane casted by electrospinning were tried to be proved by SEM, Mechanical property study, DSC and XRD studies. We have showed dramatic improvement in flexibility of poly(epsilon-caprolactone) based nanofiber matrix prepared by electrospinning method whereas solvent casting method without any plasticizer produced very brittle, inflexible film of PCL. Modulation capacity of mechanical properties is also recorded. We tried to support our opinion by citing several similar findings available in the open literature. The electrospinning method helps in plasticization and in tuning mechanical properties. PMID- 29568049 TI - Made in translation. PMID- 29568050 TI - Foldamers wave to the ribosome. PMID- 29568051 TI - Organic synthesis provides opportunities to transform drug discovery. AB - Despite decades of ground-breaking research in academia, organic synthesis is still a rate-limiting factor in drug-discovery projects. Here we present some current challenges in synthetic organic chemistry from the perspective of the pharmaceutical industry and highlight problematic steps that, if overcome, would find extensive application in the discovery of transformational medicines. Significant synthesis challenges arise from the fact that drug molecules typically contain amines and N-heterocycles, as well as unprotected polar groups. There is also a need for new reactions that enable non-traditional disconnections, more C-H bond activation and late-stage functionalization, as well as stereoselectively substituted aliphatic heterocyclic ring synthesis, C-X or C-C bond formation. We also emphasize that syntheses compatible with biomacromolecules will find increasing use, while new technologies such as machine-assisted approaches and artificial intelligence for synthesis planning have the potential to dramatically accelerate the drug-discovery process. We believe that increasing collaboration between academic and industrial chemists is crucial to address the challenges outlined here. PMID- 29568052 TI - Strategies for microbial synthesis of high-value phytochemicals. AB - Phytochemicals are of great pharmaceutical and agricultural importance, but often exhibit low abundance in nature. Recent demonstrations of industrial-scale production of phytochemicals in yeast have shown that microbial production of these high-value chemicals is a promising alternative to sourcing these molecules from native plant hosts. However, a number of challenges remain in the broader application of this approach, including the limited knowledge of plant secondary metabolism and the inefficient reconstitution of plant metabolic pathways in microbial hosts. In this Review, we discuss recent strategies to achieve microbial biosynthesis of complex phytochemicals, including strategies to: (1) reconstruct plant biosynthetic pathways that have not been fully elucidated by mining enzymes from native and non-native hosts or by enzyme engineering; (2) enhance plant enzyme activity, specifically cytochrome P450 activity, by improving efficiency, selectivity, expression or electron transfer; and (3) enhance overall reaction efficiency of multi-enzyme pathways by dynamic control, compartmentalization or optimization with the host's metabolism. We also highlight remaining challenges to - and future opportunities of - this approach. PMID- 29568053 TI - Hidden hassium. PMID- 29568054 TI - Atomic women.

AB - Emerging as an inevitable outcome of the big data era, long data are the massive amount of data that captures changes in the real world over a long period of time. In this context, recording and reading the data of a few terabytes in a single storage device repeatedly with a century-long unchanged baseline is in high demand. Here, we demonstrate the concept of optical long data memory with nanoplasmonic hybrid glass composites. Through the sintering-free incorporation of nanorods into the earth abundant hybrid glass composite, Young's modulus is enhanced by one to two orders of magnitude. This discovery, enabling reshaping control of plasmonic nanoparticles of multiple-length allows for continuous multi level recording and reading with a capacity over 10 terabytes with no appreciable change of the baseline over 600 years, which opens new opportunities for long data memory that affects the past and future. PMID- 29568056 TI - Repeatability and degree of territorial aggression differs among urban and rural great tits (Parus major). AB - Animals in urban habitats face many novel selection pressures such as increased human population densities and human disturbance. This is predicted to favour bolder and more aggressive individuals together with greater flexibility in behaviour. Previous work has focussed primarily on studying these traits in captive birds and has shown increased aggression and reduced consistency between traits (behavioural syndromes) in birds from urban populations. However, personality (consistency within a behavioural trait) has not been well studied in the wild. Here we tested whether urban free-living male great tits show greater territorial aggression than rural counterparts. We also tested predictions that both behavioural syndromes and personality would show lower consistency in urban populations. We found that urban populations were more aggressive than rural populations and urban birds appeared to show lower levels of individual behavioural repeatability (personality) as predicted. However, we found no effect of urbanisation on behavioural syndromes (correlations between multiple behavioural traits). Our results indicate that urban environments may favour individuals which exhibit increased territorial aggression and greater within trait flexibility which may be essential to success in holding urban territories. Determining how urban environments impact key fitness traits will be important in predicting how animals cope with ongoing urbanisation. PMID- 29568057 TI - Evidence that the Great Pacific Garbage Patch is rapidly accumulating plastic. AB - Ocean plastic can persist in sea surface waters, eventually accumulating in remote areas of the world's oceans. Here we characterise and quantify a major ocean plastic accumulation zone formed in subtropical waters between California and Hawaii: The Great Pacific Garbage Patch (GPGP). Our model, calibrated with data from multi-vessel and aircraft surveys, predicted at least 79 (45-129) thousand tonnes of ocean plastic are floating inside an area of 1.6 million km2; a figure four to sixteen times higher than previously reported. We explain this difference through the use of more robust methods to quantify larger debris. Over three-quarters of the GPGP mass was carried by debris larger than 5 cm and at least 46% was comprised of fishing nets. Microplastics accounted for 8% of the total mass but 94% of the estimated 1.8 (1.1-3.6) trillion pieces floating in the area. Plastic collected during our study has specific characteristics such as small surface-to-volume ratio, indicating that only certain types of debris have the capacity to persist and accumulate at the surface of the GPGP. Finally, our results suggest that ocean plastic pollution within the GPGP is increasing exponentially and at a faster rate than in surrounding waters. PMID- 29568058 TI - Innate immune adaptor TRIF deficiency accelerates disease progression of ALS mice with accumulation of aberrantly activated astrocytes. AB - There is compelling evidence that glial-immune interactions contribute to the progression of neurodegenerative diseases. The adaptive immune response has been implicated in disease processes of amyotrophic lateral sclerosis (ALS), but it remains unknown if innate immune signaling also contributes to ALS progression. Here we report that deficiency of the innate immune adaptor TIR domain-containing adaptor inducing interferon-beta (TRIF), which is essential for certain Toll-like receptor (TLR) signaling cascades, significantly shortens survival time and accelerates disease progression of ALS mice. While myeloid differentiation factor 88 (MyD88) is also a crucial adaptor for most TLR signaling pathways, MyD88 deficiency had only a marginal impact on disease course. Moreover, TRIF deficiency reduced the number of natural killer (NK), NK-T-lymphocytes, and CD8-T cells infiltrating into the spinal cord of ALS mice, but experimental modulation of these populations did not substantially influence survival time. Instead, we found that aberrantly activated astrocytes expressing Mac2, p62, and apoptotic markers were accumulated in the lesions of TRIF-deficient ALS mice, and that the number of aberrantly activated astrocytes was negatively correlated with survival time. These findings suggest that TRIF pathway plays an important role in protecting a microenvironment surrounding motor neurons by eliminating aberrantly activated astrocytes. PMID- 29568059 TI - Cell-autonomous and cell non-autonomous downregulation of tumor suppressor DAB2IP by microRNA-149-3p promotes aggressiveness of cancer cells. AB - The tumor suppressor DAB2IP contributes to modulate the network of information established between cancer cells and tumor microenvironment. Epigenetic and post transcriptional inactivation of this protein is commonly observed in multiple human malignancies, and can potentially favor progression of tumors driven by a variety of genetic mutations. Performing a high-throughput screening of a large collection of human microRNA mimics, we identified miR-149-3p as a negative post transcriptional modulator of DAB2IP. By efficiently downregulating DAB2IP, this miRNA enhances cancer cell motility and invasiveness, facilitating activation of NF-kB signaling and promoting expression of pro-inflammatory and pro-angiogenic factors. In addition, we found that miR-149-3p secreted by prostate cancer cells induces DAB2IP downregulation in recipient vascular endothelial cells, stimulating their proliferation and motility, thus potentially remodeling the tumor microenvironment. Finally, we found that inhibition of endogenous miR-149 3p restores DAB2IP activity and efficiently reduces tumor growth and dissemination of malignant cells. These observations suggest that miR-149-3p can promote cancer progression via coordinated inhibition of DAB2IP in tumor cells and in stromal cells. PMID- 29568060 TI - Freestanding photocatalytic materials based on 3D graphene and polyporphyrins. AB - A new concept in the formulation of hybrid nanostructured materials combining high quality graphene 3D supported by Nickel foam and polyporphyrins for visible light photocatalytic application is here reported. Our innovative approach involves the development of a freestanding device able to: i) offer a high surface area to bind the photosensitizers by pi-pi interactions, and ii) enhance stability and photocatalytic efficiency by using cyclic porphyrin polymers. For these purposes, homo- and co-polymerization reactions by using different porphyrin (free or zinc complexed) monomers were performed. The microscopic structures and morphology of graphene polymer nanocomposites were investigated by using Scanning Electron Microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Atomic Force Microscopy (AFM). Finally, photocatalytic activity under visible light irradiation of the obtained nanocomposites was tested, by using methylene blue (MB) as organic pollutant. The obtained data suggested that hindered cyclic polymeric structures stacked on graphene surface by non-covalent interactions, restrict the formation of non photoactive aggregates and, as a consequence, induce an enhancement of photocatalytic activity. Remarkably, our systems show a degradation efficiency in the visible-light range much higher than other similar devices containing nanoporphyrin units reported in literature. PMID- 29568061 TI - An AP-MS- and BioID-compatible MAC-tag enables comprehensive mapping of protein interactions and subcellular localizations. AB - Protein-protein interactions govern almost all cellular functions. These complex networks of stable and transient associations can be mapped by affinity purification mass spectrometry (AP-MS) and complementary proximity-based labeling methods such as BioID. To exploit the advantages of both strategies, we here design and optimize an integrated approach combining AP-MS and BioID in a single construct, which we term MAC-tag. We systematically apply the MAC-tag approach to 18 subcellular and 3 sub-organelle localization markers, generating a molecular context database, which can be used to define a protein's molecular location. In addition, we show that combining the AP-MS and BioID results makes it possible to obtain interaction distances within a protein complex. Taken together, our integrated strategy enables the comprehensive mapping of the physical and functional interactions of proteins, defining their molecular context and improving our understanding of the cellular interactome. PMID- 29568062 TI - The membrane-distal regions of integrin alpha cytoplasmic domains contribute differently to integrin inside-out activation. AB - Functioning as signal receivers and transmitters, the integrin alpha/beta cytoplasmic tails (CT) are pivotal in integrin activation and signaling. 18 alpha integrin subunits share a conserved membrane-proximal region but have a highly diverse membrane-distal (MD) region at their CTs. Recent studies demonstrated that the presence of alpha CTMD region is essential for talin-induced integrin inside-out activation. However, it remains unknown whether the non-conserved alpha CTMD regions differently regulate the inside-out activation of integrin. Using alphaIIbbeta3, alphaLbeta2, and alpha5beta1 as model integrins and by replacing their alpha CTMD regions with those of alpha subunits that pair with beta3, beta2, and beta1 subunits, we analyzed the function of CTMD regions of 17 alpha subunits in talin-mediated integrin activation. We found that the alpha CTMD regions play two roles on integrin, which are activation-supportive and activation-regulatory. The regulatory but not the supportive function depends on the sequence identity of alpha CTMD region. A membrane-proximal tyrosine residue present in the CTMD regions of a subset of alpha integrins was identified to negatively regulate integrin inside-out activation. Our study provides a useful resource for investigating the function of alpha integrin CTMD regions. PMID- 29568063 TI - Deregulation of ATG9A by impaired AR signaling induces autophagy in prostate stromal fibroblasts and promotes BPH progression. AB - The activation of androgen receptor (AR) signaling plays an essential role in both prostate stromal cells and epithelial cells during the development of benign prostatic hyperplasia (BPH). Here we demonstrated that androgen ablation after 5alpha-reductase inhibitor (5-ARI) treatment induced autophagy in prostate stromal fibroblasts inhibiting cell apoptosis. In addition, we found that ATG9A expression was increased after androgen ablation, which facilitated autophagic flux development. Knockdown of ATG9A not only inhibited autophagy notably in prostate stromal fibroblasts, but also reduced the volumes of prostate stromal fibroblast and epithelial cell recombinant grafts in nude mice. In conclusion, our findings suggested that ATG9A upregulation after long-term 5-ARI treatment constitutes a possible mechanism of BPH progression. Thus, combined treatment with 5-ARI and autophagy inhibitory agents would reduce the risk of BPH progression. PMID- 29568064 TI - BPIFB1 (LPLUNC1) inhibits radioresistance in nasopharyngeal carcinoma by inhibiting VTN expression. AB - Bactericidal/permeability-increasing-fold-containing family B member 1 (BPIFB1, previously named LPLUNC1) is highly expressed in the nasopharynx and significantly downregulated in nasopharyngeal carcinoma (NPC). Low expression is also associated with poor prognosis in patients with NPC. Radiotherapy is a routine treatment for NPC; however, radioresistance is a major cause of treatment failure. Thus, we aimed to investigate the role of BPIFB1 in the radioresponse of NPC. Colony formation and cell survival results showed that BPIFB1 sensitized NPC cells to ionizing radiation. VTN, a previously identified BPIFB1-binding protein, was shown to induce cell proliferation and survival, G2/M phase arrest, DNA repair, activation of the ATM-Chk2 and ATR-Chk1 pathways, and anti-apoptotic effects after exposure to radiation, facilitating NPC cell radioresistance. However, BPIFB1 inhibited this VTN-mediated radioresistance, ultimately improving NPC radiosensitivity. In conclusion, this study is the first to demonstrate the functions of BPIFB1 and VTN in the NPC radioresponse. Our findings indicated that promoting BPIFB1 expression and targeting VTN might represent new therapeutic strategies for NPC. PMID- 29568065 TI - A complete, homozygous CRX deletion causing nullizygosity is a new genetic mechanism for Leber congenital amaurosis. AB - CRX is a transcription factor required for activating the expression of many photoreceptor-neuron genes. CRX may be mutated in three forms of human blindness; Leber congenital amaurosis (LCA), cone-rod degeneration (CRD) and retinitis pigmentosa (RP). The pathogenic mechanism in most cases is likely dominant negative, with gain of function. We report a novel, complete homozygous CRX deletion in LCA. We identified a Lebanese family with 3 affected LCA cases. The proband was sequenced by NGS. Quantitative PCR, array comparative genomic hybridization, and long range PCR were performed. Full eye examinations, OCT and photography were performed. We identified a homozygous 56,000 bp deletion of CRX, which co-segregates and is heterozygous in four parents, who report normal vision. The blind children with LCA manifest severe retinal degeneration, a phenotype typical for CRX and LCA. We hypothesized that a single copy of CRX (haplo-insufficiency) in the causes mild abnormal foveal development, but not LCA. Two parents had significant inner and outer foveal and photoreceptor abnormalities. This is the first reported case of a homozygous, complete CRX deletion. Nullizygosity of CRX thus causes LCA while haplo-insufficiency of CRX causes abnormal foveal development, but not LCA. Our data suggest a new disease mechanism for CRX. PMID- 29568066 TI - Human transbodies that interfere with the functions of Ebola virus VP35 protein in genome replication and transcription and innate immune antagonism. AB - Small molecular inhibitors and passive immunization against Ebola virus disease (EVD) have been tested in animal models, including rodents and non-human primates, as well as in clinical trials. Nevertheless, there is currently no Food and Drug Administration (FDA)-approved therapy, and alternative strategies must be pursued. The aim of this study was to produce cell-penetrable human single chain antibodies (transbodies) that are able to interfere with the activities of interferon inhibitory domain (IID) of the VP35 protein, a multifunctional virulence factor of Ebola virus (EBOV). We speculated that effective VP35-IID specific transbodies could inspire further studies to identify an alternative to conventional antibody therapies. Phage display technology was used to generate Escherichia coli-derived human single-chain antibodies (HuscFvs) that bind to IID. HuscFvs were linked to nona-arginine (R9) to make them cell penetrable. Transbodies of transformed E. coli clones 13 and 3, which were predicted to interact with first basic patch residues (R9-HuscFv13), central basic patch, and end-cap residues (R9-HuscFv3), effectively inhibited EBOV minigenome activity. Transbodies of E. coli clones 3 and 8 antagonized VP35-mediated interferon suppression in VP35-transduced cells. We postulate that these transbodies formed an interface contact with the IID central basic patch, end-cap, and/or residues that are important for IID multimeric formation for dsRNA binding. These transbodies should be evaluated further in vitro using authentic EBOV and in vivo in animal models of EVD before their therapeutic/prophylactic effectiveness is clinically evaluated. PMID- 29568067 TI - A wide-band bio-chip for real-time optical detection of bioelectromagnetic interactions with cells. AB - The analytical and numerical design, implementation, and experimental validation of a new grounded closed coplanar waveguide for wide-band electromagnetic exposures of cells and their optical detection in real-time is reported. The realized device fulfills high-quality requirements for novel bioelectromagnetic experiments, involving elevated temporal and spatial resolutions. Excellent performances in terms of matching bandwidth (less than -10 dB up to at least 3 GHz), emission (below 1 * 10-6 W/m2) and efficiency (around 1) have been obtained as revealed by both numerical simulations and experimental measurements. A low spatial electric field inhomogeneity (coefficient of variation of around 10 %) has been achieved within the cell solutions filling the polydimethylsiloxane reservoir of the conceived device. This original bio-chip based on the grounded closed coplanar waveguide concept opens new possibilities for the development of controlled experiments combining electromagnetic exposures and sophisticated imaging using optical spectroscopic techniques. PMID- 29568068 TI - Identification of p38 MAPK as a novel therapeutic target for Friedreich's ataxia. AB - Friedreich ataxia (FRDA) is an autosomal recessive neuro- and cardio-degenerative disorder caused by decreased expression of frataxin, a protein that localizes to mitochondria and is critical for iron-sulfur-cluster (ISC) assembly. There are no proven effective treatments for FRDA. We previously screened a random shRNA library and identified a synthetic shRNA (gFA11) that reverses the growth defect of FRDA cells in culture. We now report that gFA11 decreases cytokine secretion in primary FRDA fibroblasts and reverts other changes associated with cell senescence. The gene-expression profile induced by gFA11 is remarkably similar to the gene-expression profile induced by the p38 MAPK inhibitor SB203580. We found that p38 phosphorylation, indicating activation of the p38 pathway, is higher in FRDA cells than in normal control cells, and that siRNA knockdown of frataxin in normal fibroblasts also increases p38 phosphorylation. Treatment of FRDA cells with p38 inhibitors recapitulates the reversal of the slow-growth phenotype induced by clone gFA11. These data highlight the involvement of the p38 MAPK pathway in the pathogenesis of FRDA and the potential use of p38 inhibitors as a treatment for FRDA.

AB - Damage caused by implanted helium (He) is a major concern for material performance in future nuclear reactors. We use a combination of experiments and modeling to demonstrate that amorphous silicon oxycarbide (SiOC) is immune to He induced damage. By contrast with other solids, where implanted He becomes immobilized in nanometer-scale precipitates, He in SiOC remains in solution and outgasses from the material via atomic-scale diffusion without damaging its free surfaces. Furthermore, the behavior of He in SiOC is not sensitive to the exact concentration of carbon and hydrogen in this material, indicating that the composition of SiOC may be tuned to optimize other properties without compromising resistance to implanted He. PMID- 29568070 TI - Spindle cell sarcoma: a SEER population-based analysis. AB - Due to the substantial limitation of study population, Spindle cell sarcoma (SCS) was unexplored comprehensively. In this study, we investigated the clinical characteristics and disease specific prognostic factors of SCS. 3299 SCS cases were identified and extracted from Surveillance, Epidemiology, and End Results (SEER) database (1973-2017). White people account for 79.1% with median age of 57 years without predominance in any gender. Significant disease specific survival (DSS) and overall survival (OS) were found differentiated in age, T stage, N stage, M stage, AJCC stage, SEER historic stage, tumor locations, surgery, and pathologic grade. In the multivariate Cox analysis, the age >64 years (for DSS, P < 0.001 and for OS, P < 0.001; Reference age <=64 years), AJCC stage III (for DSS, P = 0.006 and for OS, P = 0.04; Reference: AJCC stage I), and non-surgical treatment (for DSS, P < 0.001 and for OS, P < 0.001; Reference: surgery) were independently associated with worse DSS and OS. In brief, our study demonstrated that SCS mostly found in white people at fifth to seventh decades of life without gender predilection. The patient's age, AJCC stage, tumor location and surgery were independent prognostic indicators for both DSS and OS of SCS.

AB - Nervous wreck (Nwk), a protein that is present at Type 1 glutamatergic synapses that contains an SH3 domain and an FCH motif, is a Drosophila homolog of the human srGAP3/MEGAP protein, which is associated with mental retardation. Confocal microscopy revealed that circles in Nwk reticulum enclosed T-shaped active zones (T-AZs) and partially colocalized with synaptic vesicle (SV) markers and both exocytosis and endocytosis components. Results from an electron microscopic (EM) analysis showed that Nwk proteins localized at synaptic edges and in SV pools. Both the synaptic areas and the number of SVs in the readily releasable (RRPs) and reserve (RPs) SV pools in nwk2 were significantly reduced. Synergistic, morphological phenotypes observed from eag1;;nwk2 neuromuscular junctions suggested that Nwk may regulate synaptic plasticity differently from activity dependent Hebbian plasticity. Although the synaptic areas in eag1;;nwk2 boutons were not significantly different from those of nwk2, the number of SVs in the RRPs was similar to those of Canton-S. In addition, three-dimensional, high voltage EM tomographic analysis demonstrated that significantly fewer enlarged SVs were present in nwk2 RRPs. Furthermore, Nwk formed protein complexes with Drosophila Synapsin and Synaptotagmin 1 (DSypt1). Taken together, these findings suggest that Nwk is able to maintain synaptic architecture and both SV size and distribution at T-AZs by interacting with Synapsin and DSypt1. PMID- 29568073 TI - Interrupting oral infection of Porphyromonas gingivalis with anti-FimA antibody attenuates bacterial dissemination to the arthritic joint and improves experimental arthritis. AB - Rheumatoid arthritis (RA) is a chronic autoimmune disease that typically results in strong inflammation and bone destruction in the joints. It is generally known that the pathogenesis of RA is linked to cardiovascular and periodontal diseases. Though rheumatoid arthritis and periodontitis share many pathologic features such as a perpetual inflammation and bone destruction, the precise mechanism underlying a link between these two diseases has not been fully elucidated. Collagen-induced arthritis (CIA) mice were orally infected with Porphyromonas gingivalis (Pg) or Pg preincubated with an anti-FimA antibody (FimA Ab) specific for fimbriae that are flexible appendages on the cell surface. Pg-infected CIA mice showed oral microbiota disruption and increased alveolar bone loss and had synovitis and joint bone destruction. However, preincubation with FimA Ab led to a significant reduction in the severity of both oral disease and arthritis. Moreover, FimA Ab attenuated bacterial attachment and aggregation on human gingival and rheumatoid arthritis synovial fibroblasts. In addition, we discovered bacteria may utilize dendritic cells, macrophages and neutrophils to migrate into the joints of CIA mice. These results suggest that disrupting Pg fimbriae function by FimA Ab ameliorates RA. PMID- 29568074 TI - Intrahippocampal injection of a lentiviral vector expressing neurogranin enhances cognitive function in 5XFAD mice. AB - Progressive cognitive declines are the main clinical symptoms of Alzheimer's disease (AD). Cognitive impairment in AD is directly correlated with amyloid beta (Abeta)-mediated synaptic deficits. It is known that upregulation of neurogranin (Ng), a postsynaptic protein, contributes to the enhancement of synaptic plasticity and cognitive function. By contrast, downregulation of Ng expression results in learning and memory impairments. Interestingly, Ng expression is significantly reduced in the parenchyma of brains with AD. However, the pathological role that downregulated Ng plays in the cognitive dysfunctions observed in AD remains unclear. Therefore, the present study examined whether enhancing Ng expression affected cognitive functions in 5XFAD mice, an animal model of AD. We found that the Ng reductions and cognitive decline observed in 5XFAD mice were restored in mice that were intrahippocampally injected with an Ng expressing lentiviral vector. Furthermore, overexpression of Ng upregulated expression of postsynaptic density protein-95 in the hippocampus of 5XFAD mice. These results suggest that the cause of cognitive decline in AD may be at least partially associated with reduced Ng levels, and thus, supplementation of Ng may be an appropriate therapeutic strategy for individuals with AD.

AB - Hypertension-induced endothelial dysfunction is associated with beta-amyloid (Abeta) deposition, a typical pathology of Alzheimer's disease (AD). Endothelial nitric oxide synthase (eNOS) phosphorylation, impaired by phosphatidylinositol 3 kinase (PI3K)/protein kinase-B(Akt) pathway abnormalities in hypertensive rats, has a critical role in endothelial function. However, it is unknown whether eNOS participates in the hypertension-induced pathology of AD. In this study, we investigated the role of eNOS in Abeta deposition and cognitive function in stroke-prone spontaneously hypertensive (SHRSP) rats. Physical exercise was used as a promoter, and Nomega-nitro L-arginine methyl ester (L-NAME) was used as an inhibitor of eNOS to determine the effects of eNOS on SHRSP rats. Compared with Wistar Kyoto (WKY) rats, the hypertensive challenge caused cognitive impairment, decreased eNOS levels and increased amyloid precursor protein (APP), beta secretase, and Abeta levels in the cortex and hippocampus. Sixteen weeks of exercise lowered blood pressure (BP), promoted eNOS expression, ameliorated Alzheimer's pathology, and improved cognitive function in 29-week-old SHRSP rats. Furthermore, daily treatment with L-NAME reversed the beneficial effects of exercise on SHRSP rats. Exercise also decreased the protein levels of insulin like growth factor-1 (IGF-1), PI3K, and phospho-Akt (p-Akt, ser473). In addition, long-term exercise increased the expression levels of IGF-1, PI3K, and p-Akt (ser473) in the brains of SHRSP rats. In conclusion, eNOS downregulation contributed to hypertension-induced Alzheimer pathology and cognitive impairment. Long-term exercise initiated in rats at a young age promoted eNOS expression and attenuated vascular-related Alzheimer's pathology via the IGF-1/PI3K/p-Akt pathway in SHRSP rats.

PMID- 29568077 TI - Cellular response to persistent foot-and-mouth disease virus infection is linked to specific types of alterations in the host cell transcriptome. AB - Food-and-mouth disease virus (FMDV) is a highly contagious virus that seriously threatens the development of animal husbandry. Although persistent FMDV infection can dramatically worsen the situation, the mechanisms involved in persistent FMDV infection remain unclear. In the present study, we identified the presence of evolved cells in the persistently FMDV-infected cell line. These cells exhibited resistance to the parent FMDV and re-established persistent infection when infected with FMDV-Op (virus supernatant of persistent infection cell lines), emphasizing the decisive role of evolved host cells in the establishment of persistent FMDV infection. Using RNA-seq, we identified the gene expression profiles of these evolved host cells. In total, 4,686 genes were differentially expressed in evolved cells compared with normal cells, with these genes being involved in metabolic processes, cell cycle, and cellular protein catabolic processes. In addition, 1,229 alternative splicing events, especially skipped exon events, were induced in evolved cells. Moreover, evolved cells exhibited a stronger immune defensive response and weaker MAPK signal response than normal cells. This comprehensive transcriptome analysis of evolved host cells lays the foundation for further investigations of the molecular mechanisms of persistent FMDV infection and screening for genes resistant to FMDV infection.

AB - Microglia-mediated neuroinflammation is implicated in multiple neurodegenerative disorders, including Parkinson's disease (PD). Hence, the modulatioein of sustained microglial activation may have therapeutic potential. This study is designed to test the neuroprotective efficacy of taurine, a major intracellular free beta-amino acid in mammalian tissues, by using paraquat and maneb-induced PD model. Results showed that mice intoxicated with paraquat and maneb displayed progressive dopaminergic neurodegeneration and motor deficits, which was significantly ameliorated by taurine. Taurine also attenuated the aggregation of alpha-synuclein in paraquat and maneb-intoxicated mice. Mechanistically, taurine suppressed paraquat and maneb-induced microglial activation. Moreover, depletion of microglia abrogated the dopaminergic neuroprotective effects of taurine, revealing the role of microglial activation in taurine-afforded neuroprotection. Subsequently, we found that taurine suppressed paraquat and maneb-induced microglial M1 polarization and gene expression levels of proinflammatory factors. Furthermore, taurine was shown to be able to inhibit the activation of NADPH oxidase (NOX2) by interfering with membrane translocation of cytosolic subunit, p47phox and nuclear factor-kappa B (NF-kappaB) pathway, two key factors for the initiation and maintenance of M1 microglial inflammatory response. Altogether, our results showed that taurine exerted dopaminergic neuroprotection through inactivation of microglia-mediated neuroinflammation, providing a promising avenue and candidate for the potential therapy for patients suffering from PD. PMID- 29568079 TI - Pattern Formation through Temporal Fractional Derivatives. AB - It is well known that temporal first-derivative reaction-diffusion systems can produce various fascinating Turing patterns. However, it has been found that many physical, chemical and biological systems are well described by temporal fractional-derivative reaction-diffusion equations. Naturally arises an issue whether and how spatial patterns form for such a kind of systems. To address this issue clearly, we consider a classical prey-predator diffusive model with the Holling II functional response, where temporal fractional derivatives are introduced according to the memory character of prey's and predator's behaviors. In this paper, we show that this fractional-derivative system can form steadily spatial patterns even though its first-derivative counterpart can't exhibit any steady pattern. This result implies that the temporal fractional derivatives can induce spatial patterns, which enriches the current mechanisms of pattern formation.

AB - Antiaromatic and open-shell molecules are attractive because of their distinct electronic and magnetic behaviour. However, their increased reactivity creates a challenge for probing their properties. Here, we describe the on-surface and in solution generation and characterisation of a highly reactive antiaromatic molecule: indeno[1,2-b]fluorene (IF). In solution, we generated IF by KI-induced dehalogenation of a dibromo-substituted precursor molecule and found that IF survives for minutes at ambient conditions. Using atom manipulation at low temperatures we generated IF on Cu(111) and on bilayer NaCl. On these surfaces, we characterised IF by bond-order analysis using non-contact atomic force microscopy with CO-functionalised tips and by orbital imaging using scanning tunnelling microscopy. We found that the closed-shell configuration and antiaromatic character predicted for gas-phase IF are preserved on the NaCl film. On Cu(111), we observed significant bond-order reorganisation within the s indacene moiety because of chemisorption, highlighting the importance of molecule surface interactions on the pi-electron distribution. PMID- 29568082 TI - Antioxidant and prebiotic activity of five peonidin-based anthocyanins extracted from purple sweet potato (Ipomoea batatas (L.) Lam.). AB - Twelve kinds of anthocyanins from the Chinese purple sweet potato cultivar (Ipomoea batatas (L.) Lam.) were extracted and identified using LC-MS/MS, which had a high content of peonidin-based anthocyanins. Five peonidin-based anthocyanin monomers (P1, P2, P3, P4 and P5) were isolated by preparative liquid chromatography with structural analyses using an Impact II Q-TOF MS/MS. Then, the functional properties of the anthocyanin monomers, such as the antioxidant activities, proliferative effects on probiotics, and their inhibition on harmful bacteria in vitro, were investigated. The peonidin-based components in purple sweet potato anthocyanins (PSPAs) showed good properties regarding scavenging 1,1 diphenyl-2-picrylhydrazyl (DPPH) radicals and superoxide anions, and had good potential in reducing the total power activity and Fe2+ chelating ability. While the order of the antioxidant abilities was as follows: P4 > P5 > P3 > P2 > P1 > PSPAs. Microbial cultivations showed that P1, P2, P3, P4, P5 and PSPAs could induce the proliferation of Bifidobacterium bifidum, Bifidobacterium adolescentis, Bifidobacterium infantis and Lactobacillus acidophilus, and they inhibited the growth of Staphylococcus aureus and Salmonella typhimurium, suggesting the anthocyanins might have prebiotic-like activity through the modulation of the intestinal microbiota. Our results indicate that peonidin-based anthocyanins could be further utilized in health foods and pharmaceutical developments. PMID- 29568081 TI - An integrated flow cytometry-based platform for isolation and molecular characterization of circulating tumor single cells and clusters. AB - Comprehensive molecular analysis of rare circulating tumor cells (CTCs) and cell clusters is often hampered by low throughput and purity, as well as cell loss. To address this, we developed a fully integrated platform for flow cytometry-based isolation of CTCs and clusters from blood that can be combined with whole transcriptome analysis or targeted RNA transcript quantification. Downstream molecular signature can be linked to cell phenotype through index sorting. This newly developed platform utilizes in-line magnetic particle-based leukocyte depletion, and acoustic cell focusing and washing to achieve >98% reduction of blood cells and non-cellular debris, along with >1.5 log-fold enrichment of spiked tumor cells. We could also detect 1 spiked-in tumor cell in 1 million WBCs in 4/7 replicates. Importantly, the use of a large 200MUm nozzle and low sheath pressure (3.5 psi) minimized shear forces, thereby maintaining cell viability and integrity while allowing for simultaneous recovery of single cells and clusters from blood. As proof of principle, we isolated and transcriptionally characterized 63 single CTCs from a genetically engineered pancreatic cancer mouse model (n = 12 mice) and, using index sorting, were able to identify distinct epithelial and mesenchymal sub-populations based on linked single cell protein and gene expression. PMID- 29568083 TI - Identification of highly effective target genes for RNAi-mediated control of emerald ash borer, Agrilus planipennis. AB - Recent study has shown that RNA interference (RNAi) is efficient in emerald ash borer (EAB), Agrilus planipennis, and that ingestion of double-stranded RNA (dsRNA) targeting specific genes causes gene silencing and mortality in neonates. Here, we report on the identification of highly effective target genes for RNAi mediated control of EAB. We screened 13 candidate genes in neonate larvae and selected the most effective target genes for further investigation, including their effect on EAB adults and on a non-target organism, Tribolium castaneum. The two most efficient target genes selected, hsp (heat shock 70-kDa protein cognate 3) and shi (shibire), caused up to 90% mortality of larvae and adults. In EAB eggs, larvae, and adults, the hsp is expressed at higher levels when compared to that of shi. Ingestion of dsHSP and dsSHI caused mortality in both neonate larvae and adults. Administration of a mixture of both dsRNAs worked better than either dsRNA by itself. In contrast, injection of EAB.dsHSP and EAB.dsSHI did not cause mortality in T. castaneum. Thus, the two genes identified cause high mortality in the EAB with no apparent phenotype effects in a non-target organism, the red flour beetle, and could be used in RNAi-mediated control of this invasive pest.

PMID- 29568084 TI - Comparison of the Biological Characteristics of Mesenchymal Stem Cells Derived from the Human Placenta and Umbilical Cord. AB - Mesenchymal stem/stromal cells (MSCs) derived from placental tissue show great therapeutic potential and have been used in medical treatment, but the similarity and differences between the MSCs derived from various parts of the placenta remain unclear. In this study, we compared MSCs derived from different perinatal tissues, including the umbilical cord (UC), amniotic membrane (AM), chorionic plate (CP) and decidua parietalis (DP). Using human leukocyte antigen (HLA) typing and karyotype analysis, we found that the first three cell types were derived from the foetus, while the MSCs from the decidua parietalis were derived from the maternal portion of the placental tissue. Our results indicate that both foetal and maternal MSCs share a similar phenotype and multi-lineage differentiation potential, but foetal MSCs show a significantly higher expansion capacity than do maternal MSCs. Furthermore, MSCs from all sources showed significant differences in the levels of several paracrine factors. PMID- 29568086 TI - Quantifying the propagation of distress and mental disorders in social networks. AB - Heterogeneity of human beings leads to think and react differently to social phenomena. Awareness and homophily drive people to weigh interactions in social multiplex networks, influencing a potential contagion effect. To quantify the impact of heterogeneity on spreading dynamics, we propose a model of coevolution of social contagion and awareness, through the introduction of statistical estimators, in a weighted multiplex network. Multiplexity of networked individuals may trigger propagation enough to produce effects among vulnerable subjects experiencing distress, mental disorder, which represent some of the strongest predictors of suicidal behaviours. The exposure to suicide is emotionally harmful, since talking about it may give support or inadvertently promote it. To disclose the complex effect of the overlapping awareness on suicidal ideation spreading among disordered people, we also introduce a data driven approach by integrating different types of data. Our modelling approach unveils the relationship between distress and mental disorders propagation and suicidal ideation spreading, shedding light on the role of awareness in a social network for suicide prevention. The proposed model is able to quantify the impact of overlapping awareness on suicidal ideation spreading and our findings demonstrate that it plays a dual role on contagion, either reinforcing or delaying the contagion outbreak. PMID- 29568087 TI - Comparative study of afterpulsing behavior and models in single photon counting avalanche photo diode detectors. AB - Single-photon avalanche diode (SPAD) detectors, have a great importance in fields like quantum key distribution, laser ranging, florescence microscopy, etc. Afterpulsing is a non-ideal behavior of SPADs that adversely affects any application that measures the number or timing of detection events. Several studies based on a few individual detectors, derived distinct mathematical models from semiconductor physics perspectives. With a consistent testing procedure and statistically large data sets, we show that different individual detectors - even if identical in type, make, brand, etc. - behave according to fundamentally different mathematical models. Thus, every detector must be characterized individually and it is wrong to draw universal conclusions about the physical meaning behind these models. We also report the presence of high-order afterpulses that are not accounted for in any of the standard models.

PMID- 29568088 TI - Transcription factor PAX6 as a novel prognostic factor and putative tumour suppressor in non-small cell lung cancer. AB - Lung cancer is the leading cause of cancer deaths. Novel predictive biomarkers are needed to improve treatment selection and more accurate prognostication. PAX6 is a transcription factor with a proposed tumour suppressor function. Immunohistochemical staining was performed on tissue microarrays from 335 non small cell lung cancer (NSCLC) patients for PAX6. Multivariate analyses of clinico-pathological variables and disease-specific survival (DSS) was carried out, and phenotypic changes of two NSCLC cell lines with knockdown of PAX6 were characterized. While PAX6 expression was only associated with a trend of better disease-specific survival (DSS) (p = 0.10), the pN+ subgroup (N = 103) showed significant correlation between high PAX6 expression and longer DSS (p = 0.022). Median survival for pN + patients with high PAX6 expression was 127.4 months, versus 22.9 months for patients with low PAX6 expression. In NCI-H661 cells, knockdown of PAX6 strongly activated serum-stimulated migration. In NCI-H460 cells, PAX6 knockdown activated anchorage-independent growth. We did not observe any significant effect of PAX6 on proliferation in either of cell lines. Our findings strongly support the proposition of PAX6 as a valid and positive prognostic marker in NSCLC in node-positive patients. There is a need for further studies, which should provide mechanistical explanation for the role of PAX6 in NSCLC.

AB - BACKGROUND: The immediate impact of providing an antenatal dietary intervention during pregnancy has been extensively studied, but little is known of the effects beyond the neonatal period. Our objective was to evaluate the effect of an antenatal dietary intervention in overweight or obese women on infant outcomes 6 months after birth. METHODS: We conducted a follow up study of infants born to women who participated in the LIMIT trial during pregnancy. Live-born infants at 6-months of age, and whose mother provided consent to ongoing follow-up were eligible. The primary follow-up study endpoint was the incidence of infant BMI z score >=90th centile for infant sex and age. Secondary study outcomes included a range of infant anthropometric measures, neurodevelopment, general health, and infant feeding. Analyses used intention to treat principles according to the treatment group allocated in pregnancy. Missing data were imputed and analyses adjusted for maternal early pregnancy BMI, parity, study centre, socioeconomic status, age, and smoking status. Outcome assessors were blinded to the allocated treatment group. RESULTS: A total of 1754 infants were assessed at age 6 months (Lifestyle Advice n = 869; Standard Care n = 885), representing 82.1% of the eligible sample (n = 2136). There were no statistically significant differences in the incidence of infant BMI z-score >=90th centile for infants born to women in the Lifestyle Advice group, compared with the Standard Care group (Lifestyle Advice 233 (21.71%) vs. Standard Care 233 (21.90%); adjusted relative risk (aRR) 0.99; 95% confidence interval 0.82 to 1.18; p = 0.88). There were no other effects on infant growth, adiposity, or neurodevelopment. CONCLUSION: Providing pregnant women who were overweight or obese with an antenatal dietary and lifestyle intervention did not alter 6-month infant growth and adiposity. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry (ACTRN12607000161426). PMID- 29568101 TI - CYP2A6 is associated with obesity: studies in human samples and a high fat diet mouse model. AB - BACKGROUND/OBJECTIVES: CYP2A6 (CYP2A5 in mice) is mainly expressed in the liver. Hepatic CYP2A6 expression is increased in patients with non-alcoholic fatty liver disease (NAFLD). In mice, hepatic CYP2A5 is induced by high fat diet (HFD) feeding. Hepatic CYP2A5 is also increased in monosodium glutamate-induced obese mice. NAFLD is associated with obesity. In this study, we examined whether obesity is related to CYP2A6. SUBJECTS/METHODS: Obesity genetic association study: The SAGE is a comprehensive genome-wide association study (GWAS) with case subjects having a lifetime history of alcohol dependence and control subjects never addicted to alcohol. We used 1030 control individuals with self-reported height and weight. A total of 12 single nucleotide polymorphisms (SNP) within the CYP2A6 gene were available. Obesity was determined as a BMI >=30: 30-34.9 (Class I obesity) and >=35 (Class II and III obesity). Animal experiment study: CYP2A5 knockout (cyp2a5 -/- ) mice and wild type (cyp2a5 +/+ ) mice were fed HFD for 14 weeks. Body weight was measured weekly. After an overnight fast, the mice were sacrificed. Liver and blood were collected for biochemical assays. RESULTS: Single marker analysis showed that three SNPs (rs8192729, rs7256108, and rs7255443) were associated with class I obesity (p < 0.05). The most significant SNP for obesity was rs8192729 (odds ratio (OR) = 1.94, 95% confidence intervals = 1.21-3.10, p = 0.00582). After HFD feeding, body weight was increased in cyp2a5 /- mice to a greater extent than in cyp2a5 +/+ mice, and fatty liver was more pronounced in cyp2a5 -/- mice than in cyp2a5 +/+ mice. PPARalpha deficiency in cyp2a5 -/- mice developed more severe fatty liver, but body weight was not increased significantly. CONCLUSION: CYP2A6 is associated with human obesity; CYP2A5 protects against obesity and NAFLD in mice. PPARalpha contributes to the CYP2A5 protective effects on fatty liver but it opposes to the protective effects on obesity. PMID- 29568102 TI - Enhanced hexose-6-phosphate dehydrogenase expression in adipose tissue may contribute to diet-induced visceral adiposity. AB - BACKGROUND: Visceral fat accumulation increases the risk of developing type 2 diabetes and metabolic syndrome, and is associated with excessive glucocorticoids (GCs). Fat depot-specific GC action is tightly controlled by 11beta hydroxysteroid dehydrogenase (11beta-HSD1) coupled with the enzyme hexose-6 phosphate dehydrogenase (H6PDH). Mice with inactivation or activation of H6PDH genes show altered adipose 11beta-HSD1 activity and lipid storage. We hypothesized that adipose tissue H6PDH activation is a leading cause for the visceral obesity and insulin resistance. Here, we explored the role and possible mechanism of enhancing adipose H6PDH in the development of visceral adiposity in vivo. METHODS: We investigated the potential contribution of adipose H6PDH activation to the accumulation of visceral fat by characterization of visceral fat obese gene expression profiles, fat distribution, adipocyte metabolic molecules, and abdominal fat-specific GC signaling mechanisms underlying the diet induced visceral obesity and insulin resistance in H6PDH transgenic mice fed a standard of high-fat diet (HFD). RESULTS: Transgenic H6PDH mice display increased abdominal fat accumulation, which is paralleled by elevated lipid synthesis associated with induction of lipogenic transcriptor C/EBPalpha and PPARgamma mRNA levels within adipose tissue. Transgenic H6PDH mice fed a high-fat diet (HFD) gained more abdominal visceral fat mass coupled with activation of GSK3beta and induction of XBP1/IRE1alpha, but reduced pThr308 Akt/PKB content and browning gene CD137 and GLUT4 mRNA levels within the visceral adipose tissue than WT controls. HFD-fed H6PDH transgenic mice also had impaired insulin sensitivity and exhibited elevated levels of intra-adipose GCs with induction of adipose 11beta HSD1. CONCLUSION: These data provide the first in vivo mechanistic evidence for the adverse metabolic effects of adipose H6PDH activation on visceral fat distribution, fat metabolism, and adipocyte function through enhancing 11beta HSD1-driven intra-adipose GC action. PMID- 29568103 TI - Incidence of end-stage renal disease following bariatric surgery in the Swedish Obese Subjects Study. AB - BACKGROUND: Obesity is a major public health problem leading to co-morbidities such as diabetes, hypertension and kidney failure. Bariatric surgery results in pronounced and maintained weight loss and prevention of obesity-related diseases and their complications. Most studies of bariatric surgery on kidney disease show improvements after surgery. However, long-term studies analyzing hard end-points are lacking. Here we report on the long-term effects of bariatric surgery compared to usual obesity care on incidence of end-stage renal disease (ESRD) alone and in combination with chronic kidney disease stage 4 (CKD4/ESRD). METHODS: 4047 patients were included in the Swedish Obese Subjects (SOS) study. Inclusion criteria were age 37-60 years and BMI >= 34 in men and BMI >= 38 in women. Patients in the bariatric surgery group (N = 2010) underwent banding (18%), vertical banded gastroplasty (69%), or gastric bypass (13%); controls (N = 2037) received usual obesity care. In this analysis, patients were followed up for a median time of 18 years. The incidence of ESRD and CKD4 was obtained by crosschecking the SOS database with the Swedish National Patient Register. RESULTS: During follow-up, ESRD occurred in 13 patients in the surgery group and in 26 patients in the control group (adjusted hazard ratio (HR) = 0.27; 95% CI 0.12-0.60; p = 0.001). The number of CKD4/ESRD events was 23 in the surgery group and 39 in the control group (adjusted HR = 0.33; 95% CI 0.18-0.62; p < 0.001). In both analyses, bariatric surgery had a more favorable effect in patients with baseline serum insulin levels above median compared to those with lower insulin levels (interaction p = 0.010). Treatment benefit of bariatric surgery was also greater in patients with macroalbuminuria at baseline compared to those without macroalbuminuria (interaction p < 0.001). CONCLUSIONS: Our study showed for the first time that bariatric surgery is associated with a long-term protection against ESRD and CKD4/ESRD. PMID- 29568104 TI - Gut-microbiome-related LCT genotype and 2-year changes in body composition and fat distribution: the POUNDS Lost Trial. AB - BACKGROUND/OBJECTIVES: Gut microbiome regulates host energy metabolism and adiposity. A recent study identified a genome-wide significant variant in the lactase (LCT) gene that determines gut-microbiome abundance. We investigated whether the LCT variant influenced long-term changes in adiposity among overweight and obese individuals. SUBJECTS/METHODS: We included 583 whites with LCT variant rs4988235 (G allele as Bifidobacterium-abundance-increasing allele) who were randomly assigned to one of four weight-loss diets varying in macronutrient contents. Two-year changes in adiposity measures were assessed according to the LCT genotype and weight-loss diets. RESULTS: We observed a significant interaction between the LCT genotype and dietary protein intake on changes in whole body total fat mass %, trunk fat %, superficial adipose tissue mass (SAT), visceral adipose tissue mass (VAT), and total adipose tissue mass (TAT) (Pinteraction < 0.05 for all). In response to high-protein diet, carrying the G allele of LCT variant rs4988235 was associated with greater reduction of whole body total fat mass % (beta [SE] -0.9 [0.43], P = 0.04), trunk fat % (-1.06 [0.58], P = 0.07), SAT (-0.89 [0.42], P = 0.04), VAT (-0.63 [0.27], P = 0.03), and TAT (-1.69 [0.76], P = 0.03). Conversely, increasing numbers of the G allele tended to be related to less reduction of these outcomes in response to low protein diet. CONCLUSIONS: Long-term improvement of body fat composition and distribution was significantly influenced by the Bifidobacterium-related LCT genotype and dietary protein intake. Overweight and obese individuals with the G allele of LCT variant rs4988235 may benefit improving adiposity by eating a low calorie, high-protein diet. PMID- 29568105 TI - Early childhood BMI trajectories in monogenic obesity due to leptin, leptin receptor, and melanocortin 4 receptor deficiency. AB - OBJECTIVE: To evaluate whether early childhood body mass index (BMI) is an appropriate indicator for monogenic obesity. METHODS: A cohort of n = 21 children living in Germany or Austria with monogenic obesity due to congenital leptin deficiency (group LEP, n = 6), leptin receptor deficiency (group LEPR, n = 6) and primarily heterozygous MC4 receptor deficiency (group MC4R, n = 9) was analyzed. A control group (CTRL) was defined that consisted of n = 22 obese adolescents with no mutation in the above mentioned genes. Early childhood (0-5 years) BMI trajectories were compared between the groups at selected time points. RESULTS: The LEP and LEPR group showed a tremendous increase in BMI during the first 2 years of life with all patients displaying a BMI >27 kg/m2 (27.2-38.4 kg/m2) and %BMIP95 (percentage of the 95th percentile BMI for age and sex) >140% (144.8 198.6%) at the age of 2 years and a BMI > 33 kg/m2 (33.3-45.9 kg/m2) and %BMIP95 > 184% (184.1-212.6%) at the age of 5 years. The MC4R and CTRL groups had a later onset of obesity with significantly lower BMI values at both time points (p < 0.01). CONCLUSION: As result of the investigation of early childhood BMI trajectories in this pediatric cohort with monogenic obesity we suggest that BMI values >27.0 kg/m2 or %BMIP95 > 140% at the age of 2 years and BMI values >33.0 kg/m2 or %BMIP95 > 184% at the age of 5 years may be useful cut points to identify children who should undergo genetic screening for monogenic obesity due to functionally relevant mutations in the leptin gene or leptin receptor gene. PMID- 29568106 TI - Socioeconomic differences in childhood BMI trajectories in Belarus. AB - OBJECTIVE: To examine associations of parental socioeconomic position with early life offspring body mass index (BMI) trajectories in a middle-income country. SUBJECTS: Overall, 12,385 Belarusian children born 1996-97 and enrolled in a randomised breastfeeding promotion trial at birth, with 3-14 measurements of BMI from birth to 7 years. METHODS: Cohort analysis in which exposures were parental education (common secondary or less; advanced secondary or partial university; completed university) and occupation (manual; non-manual) at birth, and the outcome was BMI z-score trajectories estimated using multilevel linear spline models, controlling for trial arm, location, parental BMI, maternal smoking status and number of older siblings. RESULTS: Infants born to university-educated mothers were heavier at birth than those born to secondary school-educated mothers [by 0.13 BMI z-score units (95% confidence interval, CI: 0.07, 0.19) for girls and 0.11 (95% CI: 0.05, 0.17) for boys; equivalent for an infant of average birth length to 43 and 38 g, respectively]. Between the ages of 3-7 years children of the most educated mothers had larger BMI increases than children of the least educated mothers. At age 7 years, after controlling for trial arm and location, children of university-educated mothers had higher BMIs than those born to secondary school-educated mothers by 0.11 z-score (95% CI: 0.03, 0.19) among girls and 0.18 (95% CI: 0.1, 0.27) among boys, equivalent to differences in BMI for a child of average height of 0.19 and 0.26 kg/m2, respectively. After further controlling for parental BMI, these differences attenuated to 0.08 z score (95% CI: 0, 0.16) and 0.16 z-score (95% CI: 0.07, 0.24), respectively, but changed very little after additional adjustment for number of older siblings and mother's smoking status. Associations were similar when based on paternal educational attainment and highest household occupation. CONCLUSIONS: In Belarus, consistent with some middle-income countries, higher socioeconomic position was associated with greater BMI trajectories from age 3 onwards. PMID- 29568107 TI - Augmented capacity for peripheral serotonin release in human obesity. AB - BACKGROUND/OBJECTIVES: Evidence from animal studies highlights an important role for serotonin (5-HT), derived from gut enterochromaffin (EC) cells, in regulating hepatic glucose production, lipolysis and thermogenesis, and promoting obesity and dysglycemia. Evidence in humans is limited, although elevated plasma 5-HT concentrations are linked to obesity. SUBJECTS/METHODS: We assessed (i) plasma 5 HT concentrations before and during intraduodenal glucose infusion (4 kcal/min for 30 min) in non-diabetic obese (BMI 44 +/- 4 kg/m2, N = 14) and control (BMI 24 +/- 1 kg/m2, N = 10) subjects, (ii) functional activation of duodenal EC cells (immunodetection of phospho-extracellular related-kinase, pERK) in response to glucose, and in separate subjects, (iii) expression of tryptophan hydroxylase-1 (TPH1) in duodenum and colon (N = 39), and (iv) 5-HT content in primary EC cells from these regions (N = 85). RESULTS: Plasma 5-HT was twofold higher in obese than control responders prior to (P = 0.025), and during (iAUC, P = 0.009), intraduodenal glucose infusion, and related positively to BMI (R2 = 0.334, P = 0.003) and HbA1c (R2 = 0.508, P = 0.009). The density of EC cells in the duodenum was twofold higher at baseline in obese subjects than controls (P = 0.023), with twofold more EC cells activated by glucose infusion in the obese (EC cells co expressing 5-HT and pERK, P = 0.001), while the 5-HT content of EC cells in duodenum and colon was similar; TPH1 expression was 1.4-fold higher in the duodenum of obese subjects (P = 0.044), and related positively to BMI (R2 = 0.310, P = 0.031). CONCLUSIONS: Human obesity is characterized by an increased capacity to produce and release 5-HT from the proximal small intestine, which is strongly linked to higher body mass, and glycemic control. Gut-derived 5-HT is likely to be an important driver of pathogenesis in human obesity and dysglycemia. PMID- 29568108 TI - Lifestyle of women before pregnancy and the risk of offspring obesity during childhood through early adulthood. AB - BACKGROUND: In women, adhering to an overall healthy lifestyle is associated with a dramatically reduced risk of cardio-metabolic disorders. Whether such a healthy lifestyle exerts an intergenerational effects on child health deserves examination. METHODS: We included 5701 children (9-14 years old at baseline) of the Growing Up Today Study 2, and their mothers, who are participants in the Nurses' Health Study II. Pre-pregnancy healthy lifestyle was defined as a normal body mass index, no smoking, physical activity >=150 min/week, and diet in the top 40% of the Alternative Healthy Eating Index-2010. Obesity during childhood and adolescence was defined using the International Obesity Task Force age- and sex-specific cutoffs. Multivariable log-binominal regression models with generalized estimating equations were used to evaluate the association of pre pregnancy healthy lifestyle and offspring obesity. RESULTS: We identified 520 (9.1%) offspring who became obese during follow-up. A healthy body weight of mothers and no smoking before pregnancy was significantly associated with a lower risk of obesity among offspring: the relative risks [RRs; 95% confidence intervals (CIs)] were 0.37 (0.31-0.43) and 0.64 (0.49-0.84), respectively. Eating a healthy diet and regular moderate-to-vigorous physical activities were inversely related to offspring obesity risk, but these relations were not statistically significant. Compared to children of mothers who did not meet any low-risk lifestyle factors, offspring of women who adhered to all four healthy lifestyle factors had 75% lower risk of obesity (RR: 0.25, 95% CI: 0.14-0.43). CONCLUSION: Adherence to an overall healthy lifestyle before pregnancy is strongly associated with a low risk of offspring obesity in childhood, adolescence, and early adulthood. These findings highlight the importance of an overall healthy lifestyle before pregnancy as a potential strategy to prevent obesity in future generations. PMID- 29568110 TI - Compositional associations of time spent in sleep, sedentary behavior and physical activity with obesity measures in children. AB - BACKGROUND/OBJECTIVES: The 24 h day is made up of four movement behaviors: sleep, sedentary behavior (SB), light intensity physical activity (LIPA), and moderate to-vigorous physical activity (MVPA). Previous studies examining associations between movement behaviors and obesity have used flawed statistical methods that did not account for the co-dependent and compositional nature of movement behaviors. Our objective was to use compositional data analysis methods to investigate the relationships between movement behaviors and obesity measures among children. SUBJECTS/METHODS: Participants were 434 children aged 10-13 years. They wore an accelerometer for 7 days to determine time spent in SB, LIPA, and MVPA. Sleep duration was determined from the accelerometer and a log. The obesity measures were the body mass index, waist circumference, and fat mass index. Compositional data analysis was used to estimate whether the composition of movement behaviors was associated with obesity measures, and the extent to which changing time in movement behaviors within the movement behavior composition was associated with changes in obesity measures. RESULTS: The composition of movement behaviors across the 24 h day was associated with all three obesity measures (p < 0.001). Relative to other movement behaviors, time spent in MVPA was negatively associated with obesity measures (p < 0.01), time spent in LIPA was positively associated with obesity measures (p < 0.05), while time spent in SB and sleep were not associated with obesity measures. The estimates suggested that an 18 min/day increase in MVPA, 21 min/day decrease in LIPA, 87 min/day decrease in SB, or 67 min/day increase in sleep relative to the remaining behaviors would be associated with a 0.1 unit decrease in BMI z-score. CONCLUSIONS: The composition of movement behaviors across the day is associated with obesity measures. The findings suggest that changing the movement behavior composition by increasing MVPA and decreasing LIPA would be the most effective approach for improving obesity measures. PMID- 29568109 TI - Mitochondrial inefficiency in infants born to overweight African-American mothers. AB - BACKGROUND: Currently 20-35% of pregnant women are obese, posing a major health risk for mother and fetus. It is postulated that an abnormal maternal-fetal nutritional environment leads to adverse metabolic programming, resulting in altered substrate metabolism in the offspring and predisposing to risks of obesity and diabetes later in life. Data indicate that oocytes from overweight animals have abnormal mitochondria. We hypothesized that maternal obesity is associated with altered mitochondrial function in healthy neonatal offspring. METHODS: Overweight and obese (body mass index, (BMI) >= 25 kg/m2, n = 14) and lean (BMI < 25 kg/m2, n = 8), African-American pregnant women carrying male fetuses were recruited from the Barnes Jewish Hospital obstetric clinic. Maternal and infant data were extracted from medical records. Infants underwent body composition testing in the first days of life. Circumcision skin was collected for isolation of fibroblasts. Fibroblast cells were evaluated for mitochondrial function, metabolic gene expression, nutrient uptake, and oxidative stress. RESULTS: Skin fibroblasts of infants born to overweight mothers had significantly higher mitochondrial respiration without a concurrent increase in ATP production, indicating mitochondrial inefficiency. These fibroblasts had higher levels of reactive oxygen species and evidence of oxidative stress. Evaluation of gene expression in offspring fibroblasts revealed altered expression of multiple genes involved in fatty acid and glucose metabolism and mitochondrial respiration in infants of overweight mothers. CONCLUSIONS: This study demonstrates altered mitochondrial function and oxidative stress in skin fibroblasts of infants born to overweight mothers. Future studies are needed to determine the long-term impact of this finding on the metabolic health of these children.

PMID- 29568112 TI - Model formulation of microbial CO2 production and efficiency can significantly influence short and long term soil C projections. PMID- 29568113 TI - Multiple mechanisms drive phage infection efficiency in nearly identical hosts. AB - Phage-host interactions are critical to ecology, evolution, and biotechnology. Central to those is infection efficiency, which remains poorly understood, particularly in nature. Here we apply genome-wide transcriptomics and proteomics to investigate infection efficiency in nature's own experiment: two nearly identical (genetically and physiologically) Bacteroidetes bacterial strains (host18 and host38) that are genetically intractable, but environmentally important, where phage infection efficiency varies. On host18, specialist phage phi18:3 infects efficiently, whereas generalist phi38:1 infects inefficiently. On host38, only phi38:1 infects, and efficiently. Overall, phi18:3 globally repressed host18's transcriptome and proteome, expressed genes that likely evaded host restriction/modification (R/M) defenses and controlled its metabolism, and synchronized phage transcription with translation. In contrast, phi38:1 failed to repress host18's transcriptome and proteome, did not evade host R/M defenses or express genes for metabolism control, did not synchronize transcripts with proteins and its protein abundances were likely targeted by host proteases. However, on host38, phi38:1 globally repressed host transcriptome and proteome, synchronized phage transcription with translation, and infected host38 efficiently. Together these findings reveal multiple infection inefficiencies. While this contrasts the single mechanisms often revealed in laboratory mutant studies, it likely better reflects the phage-host interaction dynamics that occur in nature. PMID- 29568115 TI - The long and latent road to autoimmunity. PMID- 29568114 TI - Population genomic analysis of the rice blast fungus reveals specific events associated with expansion of three main clades. AB - We examined the genomes of 100 isolates of Magnaporthe oryzae (Pyricularia oryzae), the causal agent of rice blast disease. We grouped current field populations of M. oryzae into three major globally distributed groups. A genetically diverse group, clade 1, which may represent a group of closely related lineages, contains isolates of both mating types. Two well-separated clades, clades 2 and 3, appear to have arisen as clonal lineages distinct from the genetically diverse clade. Examination of genes involved in mating pathways identified clade-specific diversification of several genes with orthologs involved in mating behavior in other fungi. All isolates within each clonal lineage are of the same mating type. Clade 2 is distinguished by a unique deletion allele of a gene encoding a small cysteine-rich protein that we determined to be a virulence factor. Clade 3 isolates have a small deletion within the MFA2 pheromone precursor gene, and this allele is shared with an unusual group of isolates we placed within clade 1 that contain AVR1-CO39 alleles. These markers could be used for rapid screening of isolates and suggest specific events in evolution that shaped these populations. Our findings are consistent with the view that M. oryzae populations in Asia generate diversity through recombination and may have served as the source of the clades 2 and 3 isolates that comprise a large fraction of the global population.

PMID- 29568117 TI - Distinct contribution of PD-L1 suppression by spatial expression of PD-L1 on tumor and non-tumor cells. AB - Programmed cell death receptor 1 (PD-1) and its ligand, PD-L1, are important immune checkpoint proteins. Although antibodies that block PD-1/PD-L1 have shown promising clinical efficacy in a subset of cancer patients, the detailed cellular and molecular mechanisms behind anti-PD-1 and anti-PD-L1 immunotherapy are not well defined. Specifically, the way in which PD-L1 contributes to immune suppression on tumor and non-tumor cells remains controversial. By selectively blocking PD-L1 on either tumor or non-tumor cells, we demonstrated that PD-L1 from both sources suppressed the anti-tumor T-cell response. Blocking PD-L1 on either tumor cells or non-tumor cells inhibited tumor growth and enhanced immune cell infiltration, as well as the tumor-specific T-cell response. Further, simultaneously blocking tumor- and non-tumor-derived PD-L1 maximized anti-tumor T cell responses and demonstrated synergy. In addition, the relative contribution of PD-L1 on tumor and non-tumor cells to immune suppression depended on the PD-L1 expression level. Lastly, we found that the F4/80 receptor was involved in the anti-tumor effect of PD-L1 blockade. Taken together, our data indicate that PD-L1 on both tumor and non-tumor cells is critical for T-cell inhibition, which provides new directions for the optimization of PD-L1-blocking antibodies and the development of clinical biomarker strategies. PMID- 29568119 TI - TREM-1 multimerization is essential for its activation on monocytes and neutrophils. AB - The triggering receptor expressed on myeloid cells-1 (TREM-1) is a receptor expressed on innate immune cells. By promoting the amplification of inflammatory signals that are initially triggered by Toll-like receptors (TLRs), TREM-1 has been characterized as a major player in the pathophysiology of acute and chronic inflammatory diseases, such as septic shock, myocardial infarction, atherosclerosis, and inflammatory bowel diseases. However, the molecular events leading to the activation of TREM-1 in innate immune cells remain unknown. Here, we show that TREM-1 is activated by multimerization and that the levels of intracellular Ca2+ release, reactive oxygen species, and cytokine production correlate with the degree of TREM-1 aggregation. TREM-1 activation on primary human monocytes by LPS required a two-step process consisting of upregulation followed by clustering of TREM-1 at the cell surface, in contrast to primary human neutrophils, where LPS induced a rapid cell membrane reorganization of TREM 1, which confirmed that TREM-1 is regulated differently in primary human neutrophils and monocytes. In addition, we show that the ectodomain of TREM-1 is able to homooligomerize in a concentration-dependent manner, which suggests that the clustering of TREM-1 on the membrane promotes its oligomerization. We further show that the adapter protein DAP12 stabilizes TREM-1 surface expression and multimerization. TREM-1 multimerization at the cell surface is also mediated by its endogenous ligand, a conclusion supported by the ability of the TREM-1 inhibitor LR12 to limit TREM-1 multimerization. These results provide evidence for ligand-induced, receptor-mediated dimerization of TREM-1. Collectively, our findings uncover the mechanisms necessary for TREM-1 activation in monocytes and neutrophils. PMID- 29568118 TI - The cellular metabolic landscape in the tumor milieu regulates the activity of myeloid infiltrates. AB - Malignant cells upregulate distinct energy metabolism programs that support their proliferation, migration, and adaptation to the stressful tumor microenvironment (TME). Additionally, this exaggerated metabolic activity allows cancer cells to hijack essential nutrients and outcompete neighboring infiltrating immune cells, thereby impairing antitumor immunity. During recent years, there has been great interest in the field to understand the tumor-induced energy metabolism signals that regulate the function of immune cells in individuals with cancer. Accordingly, it is now well accepted that uncovering the mechanisms that instruct the metabolic behavior of cancer cells and tumor-associated immune cells is an indispensable strategy for the development of new approaches to overcome immune suppression in tumors. Thus, in this minireview, we briefly discuss the interaction between particular metabolic signaling pathways and immunosuppressive activity in different subsets of myeloid cells within the TME. Additionally, we illustrate potential central mechanisms controlling the metabolic reprogramming of myeloid cells in response to tumor-derived factors. PMID- 29568120 TI - Role of Hippo signaling in regulating immunity. AB - The Hippo signaling pathway has been established as a key regulator of organ size control, tumor suppression, and tissue regeneration in multiple organisms. Recently, emerging evidence has indicated that Hippo signaling might play an important role in regulating the immune system in both Drosophila and mammals. In particular, patients bearing a loss-of-function mutation of MST1 are reported to have an autosomal recessive primary immunodeficiency syndrome. MST1/2 kinases, the mammalian orthologs of Drosophila Hippo, may activate the non-canonical Hippo signaling pathway via MOB1A/B and/or NDR1/2 or cross-talk with other essential signaling pathways to regulate both innate and adaptive immunity. In this review, we present and discuss recent findings of cellular mechanisms/functions of Hippo signaling in the innate immunity in Drosophila and in mammals, T cell immunity, as well as the implications of Hippo signaling for tumor immunity. PMID- 29568121 TI - The role of transcriptional factor D-site-binding protein in circadian CCL2 gene expression in anti-Thy1 nephritis. AB - Mesangial proliferative glomerulonephritis (MsPGN) is an inflammatory disease, but both the nature of disease progression and its regulation remain unclear. In the present study, we monitored the course of anti-Thy1 nephritis from days 1 to 5 and established gene expression profiles at each time point using microarrays to explore the development of inflammation. According to the gene expression profiles, macrophage infiltration (triggered by CCL2 activation) was evident on day 1 and enhanced inflammation over the next few days. We screened for genes with expression levels similar to CCL2 and found that the upregulation of the circadian gene albumin D-site-binding protein (DBP) was involved in CCL2 activation in mesangial cells. More importantly, CCL2 expression showed oscillatory changes similar to DBP, and DBP induced peak CCL2 expression at 16:00 a clock on day 1 in the anti-Thy1 nephritis model. We knocked down DBP through transfection with a small interfering RNA (siRNA) and used RNA sequencing to identify the DBP-regulated TNF-alpha-CCL2 pathway. We performed chromatin immunoprecipitation sequencing (ChIP-Seq) and the dual luciferase assay to show that DBP bound to the TRIM55 promoter, regulating gene expression and in turn controlling the TNF-alpha-CCL2 pathway. In conclusion, DBP-regulated circadian CCL2 expression by the TRIM55-TNF pathway in injured mesangial cells at an early stage, which promoted macrophage recruitment and in turn triggered infiltration and inflammation in a model of anti-Thy1 nephritis. PMID- 29568122 TI - Evaluation of selected insomnia predictors in adolescents and young adults with cystic fibrosis. AB - AIMS AND BACKGROUND: The purpose of the study was to assess the incidence of insomnia in adolescents and young adults with cystic fibrosis and its impact on the quality of life, and to examine whether demographic and clinical factors and negative emotional states are predictors of insomnia in these patients. METHODS: The study was conducted among 95 cystic fibrosis patients aged 14-25 years. The study used a personal questionnaire survey, the Athens Insomnia Scale, the Cystic Fibrosis Quality of Life Questionnaire, the Hospital Anxiety and Depression Scale, and the Numeric Rating Scale. RESULTS: Insomnia was diagnosed in 38% of cystic fibrosis patients. In patients with insomnia, the level of anxiety (Me: 10 vs. 4; P=0.000) and depression (Me: 6.5 vs. 2; P=0.000) was significantly higher than in the good sleep quality group. The risk of insomnia increases as anxiety (OR: 4.31; 95% CI: 2.20 to 8.41) and depressive symptoms exacerbate (OR: 4.98; 95% CI: 1.84 to 13.43). Insomnia significantly worsens the quality of life in cystic fibrosis patients (beta=-0.5, P=0.000). CONCLUSION: Insomnia affects a large percentage of cystic fibrosis patients, and anxiety and depression are factors that increase the risk of insomnia. Insomnia decreases the quality of life in cystic fibrosis patients. PMID- 29568123 TI - Non-instrumental clinical monitoring does not guarantee an adequate course of general anesthesia. A prospective clinical study. AB - BACKGROUND: Clinical monitoring is the most common method of adjusting the appropriate level of general anesthesia. However, episodes of intraoperative awareness (AWR) are still reported, suggesting that clinical observations may not be sufficient in some cases. The objective of this study was to compare the efficacy of clinical and instrumental neuromonitoring with auditory evoked potentials (AEP) in an intraoperative analysis of the proper level of general anesthesia. METHODS: Patients scheduled for elective surgery were randomly divided into two groups. Subjects in the first group underwent intravenous, in the second group volatile anesthesia. The adequacy of anesthesia was analyzed using clinical parameters. All the participants were instrumentally monitored with the autoregressive AEP index (AAI). After the anesthesia, patients filled out a questionnaire on possible AWR. RESULTS: Data of 208 patients (87 in the first, and 121 in the second group) were analyzed. Before surgery there were no changes in AAI values between groups (80 vs. 78, P=0.5192). The mean values of clinical parameters changed, but five minutes after the nociceptive stimuli. The mean values of AAI at analyzed time points were specific for general anesthesia. In patients under intravenous anesthesia, we found more episodes of too low (46/608 vs.15/847, P<0.000) anesthesia. One case of AWR was found in the TIVA group. CONCLUSIONS: AAI index is good indicator of patients' level of consciousness during general anesthesia. Standard clinical monitoring provides appropriate level of the procedure. However, it is insufficient during TIVA and does not prevent episodes of AWR. PMID- 29568124 TI - How Does Household Income Affect Child Personality Traits and Behaviors? AB - We examine the effects of a quasi-experimental unconditional household income transfer on child emotional and behavioral health and personality traits. Using longitudinal data, we find that there are large beneficial effects on children's emotional and behavioral health and personality traits during adolescence. We find evidence that these effects are most pronounced for children who start out with the lowest initial endowments. The income intervention also results in improvements in parental relationships which we interpret as a potential mechanism behind our findings. PMID- 29568126 TI - Reimagining GIScience for relational spaces. AB - A mismatch between largely absolute Newtonian models of space in GIScience and the relational spaces of critical human geography has contributed to mutual disinterest between the fields. Critical GIS has offered an intellectual critique of GIScience without substantially altering how particular key geographical concepts are expressed in data structures. Although keystone ideas in GIScience such as Tobler's "First Law" and the modifiable areal unit problem speak to enduring concerns of human geography, they have drawn little interest from that field. Here, we suggest one way to reformulate the computational approach to the region for relational space, so that regions emerge not through proximity in an absolute space or similarities in intensive properties, but according to their similarities in relations. We show how this might operate theoretically and empirically, working through three illustrative examples. Our approach gestures toward reformulating key terms in GIScience like distance, proximity, networks, and spatial building blocks such as the polygon. Re-engaging the challenges of representing geographical concepts computationally can yield new kinds of GIS and GIScience resonant with theoretical ideas in human geography, and also lead to critical human geographic practices less antagonistic to computation. PMID- 29568125 TI - THE EARTH SYSTEM PREDICTION SUITE: Toward a Coordinated U.S. Modeling Capability. AB - The Earth System Prediction Suite (ESPS) is a collection of flagship U.S. weather and climate models and model components that are being instrumented to conform to interoperability conventions, documented to follow metadata standards, and made available either under open source terms or to credentialed users. The ESPS represents a culmination of efforts to create a common Earth system model architecture, and the advent of increasingly coordinated model development activities in the U.S. ESPS component interfaces are based on the Earth System Modeling Framework (ESMF), community-developed software for building and coupling models, and the National Unified Operational Prediction Capability (NUOPC) Layer, a set of ESMF-based component templates and interoperability conventions. This shared infrastructure simplifies the process of model coupling by guaranteeing that components conform to a set of technical and semantic behaviors. The ESPS encourages distributed, multi-agency development of coupled modeling systems, controlled experimentation and testing, and exploration of novel model configurations, such as those motivated by research involving managed and interactive ensembles. ESPS codes include the Navy Global Environmental Model (NavGEM), HYbrid Coordinate Ocean Model (HYCOM), and Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS(r)); the NOAA Environmental Modeling System (NEMS) and the Modular Ocean Model (MOM); the Community Earth System Model (CESM); and the NASA ModelE climate model and GEOS-5 atmospheric general circulation model.

AB - An experimental study has been carried out to investigate the behaviour of co bonded carbon fibre reinforced plastics joints with a novel design incorporating a through the thickness local reinforcement. Different specimens were manufactured to investigate static and fatigue behaviour, as well as delamination size after impact and damage tolerance characteristics. The mechanical performances of the specimens with local reinforcement, consisting of the insertion of spiked thin metal sheets between co-bonded laminates, were compared with those ones obtained from specimens with purely co-bonded joints. This novel design demonstrated by tests that damage progression under cycling load results significantly delayed by the reinforcements. A significant number of experimental results were obtained that can be used to define preliminary design guidelines. PMID- 29568128 TI - The role of Bezier extraction in adaptive isogeometric analysis: Local refinement and hierarchical refinement. AB - We present 2 adaptive refinement techniques, namely, adaptive local refinement and adaptive hierarchical refinement, for isogeometric analysis. An element-wise point of view is adopted, exploiting Bezier extraction, which facilitates the implementation of adaptive refinement in isogeometric analysis. Locally refined and hierarchical T-splines are used for the description of the geometry as well as for the approximation of the solution space in the analysis. The refinement is conducted with the aid of a subdivision operator, which is computed by again exploiting the Bezier extraction operator. The concept and algorithm of an element-based adaptive isogeometric analysis are illustrated. Numerical examples are given to examine the accuracy, the convergence, and the condition number.

PMID- 29568130 TI - An evaluation of the performance and suitability of R * C methods for ecological inference with known true values. AB - Ecological inference refers to the study of individuals using aggregate data and it is used in an impressive number of studies; it is well known, however, that the study of individuals using group data suffers from an ecological fallacy problem (Robinson in Am Sociol Rev 15:351-357, 1950). This paper evaluates the accuracy of two recent methods, the Rosen et al. (Stat Neerl 55:134-156, 2001) and the Greiner and Quinn (J R Stat Soc Ser A (Statistics in Society) 172:67-81, 2009) and the long-standing Goodman's (Am Sociol Rev 18:663-664, 1953; Am J Sociol 64:610-625, 1959) method designed to estimate all cells of R * C tables simultaneously by employing exclusively aggregate data. To conduct these tests we leverage on extensive electoral data for which the true quantities of interest are known. In particular, we focus on examining the extent to which the confidence intervals provided by the three methods contain the true values. The paper also provides important guidelines regarding the appropriate contexts for employing these models. PMID- 29568131 TI - Causal conditions for loneliness: a set-theoretic analysis on an adult sample in the UK. AB - While age has been identified as a risk factor for loneliness, whether it is a necessary or sufficient condition for loneliness has never been examined. This is the first study that applies fuzzy-set QCA, a special type of set-theoretic method, to discover the necessary and sufficient causal conditions for loneliness, respectively, among adults in the UK, analysing the data collected from the UK sample of Round 6 of the European Social Survey (ESS, 2012, n = 2163). It firstly examines the configurations of five conditions: being female, old age, not living with spouse/partner, bad health, and not being frequently social with others. Gender was found neither a necessary nor a sufficient condition for loneliness, and old age was close to being a necessary condition and became necessary when united with any of the other conditions; the configuration of not living with spouse/partner and not healthy and not frequently social with others is a sufficient condition. Robustness of results was tested with two different conditions (a limiting illness and a confidante), and a separate analysis on the absence of loneliness was conducted. The effect of the unbalanced distribution of cases across different values of the outcome was highlighted as a source of uncertainty, and the results on the absence of loneliness are different from those on its presence. PMID- 29568132 TI - The hierarchical age-period-cohort model: Why does it find the results that it finds? AB - It is claimed the hierarchical-age-period-cohort (HAPC) model solves the age period-cohort (APC) identification problem. However, this is debateable; simulations show situations where the model produces incorrect results, countered by proponents of the model arguing those simulations are not relevant to real life scenarios. This paper moves beyond questioning whether the HAPC model works, to why it produces the results it does. We argue HAPC estimates are the result not of the distinctive substantive APC processes occurring in the dataset, but are primarily an artefact of the data structure-that is, the way the data has been collected. Were the data collected differently, the results produced would be different. This is illustrated both with simulations and real data, the latter by taking a variety of samples from the National Health Interview Survey (NHIS) data used by Reither et al. (Soc Sci Med 69(10):1439-1448, 2009) in their HAPC study of obesity. When a sample based on a small range of cohorts is taken, such that the period range is much greater than the cohort range, the results produced are very different to those produced when cohort groups span a much wider range than periods, as is structurally the case with repeated cross-sectional data. The paper also addresses the latest defence of the HAPC model by its proponents (Reither et al. in Soc Sci Med 145:125-128, 2015a). The results lend further support to the view that the HAPC model is not able to accurately discern APC effects, and should be used with caution when there appear to be period or cohort near-linear trends. PMID- 29568133 TI - The adequacy of measures of gender roles attitudes: a review of current measures in omnibus surveys. AB - The measures of attitudes toward gender roles included in many representative international and national omnibus surveys were developed mostly in the 1970s and 1980s with a focus on the male breadwinner model. This article deals with the issue of whether the measures provided in these omnibus surveys need to be adjusted to specific social changes. A review of these measures has found that adjustments have occurred in a limited way that focused on the role of women and disregarded the role of men. Furthermore, most of these measures only examined the traditional roles of men and women. More egalitarian role models have not been considered sufficiently. In addition, most items that have been measured are phrased in a general form and, for example, do not specify parents' employment or the ages of children. A specification of these aspects of measurement would help to clarify the conceptual meaning of the results and increase the possibility of more accurately analyzing gender role attitudes over time.

AB - The study examines the association between the size of previous environmental sanction charges and subsequent compliance towards environmental regulations. Data used for the study come from about 9000 Swedish firms fined sometime between January 2002 and December 2012. Probabilities of compliance across various levels of sanctions are estimated using life-table methods and tested for equality using standard nonparametric methods. Association between size of sanction charges and subsequent behaviour is modelled by proportional hazard model for the rate of recidivism as well as by a family of flexible parametric accelerated failure-time models for the duration of compliance. The results show that duration of compliance may be described by a log-normal distribution. Further, it is demonstrated that sanctions charges do have significant detering effects on the risk of recidivism though the strength of the detering effect depends on whether or not we account for other possible correlates of recidivism. Possible explanations of the results and their policy implications are discussed; limitations of the current study highlighted; and potential extensions for future studies outlined.

AB - The use of computer-based automation and control systems for smart sustainable buildings, often so-called Automated Buildings (ABs), has become an effective way to automatically control, optimize, and supervise a wide range of building performance applications over a network while achieving the minimum energy consumption possible, and in doing so generally refers to Building Automation and Control Systems (BACS) architecture. Instead of costly and time-consuming experiments, this paper focuses on using distributed dynamic simulations to analyze the real-time performance of network-based building control systems in ABs and improve the functions of the BACS technology. The paper also presents the development and design of a distributed dynamic simulation environment with the capability of representing the BACS architecture in simulation by run-time coupling two or more different software tools over a network. The application and capability of this new dynamic simulation environment are demonstrated by an experimental design in this paper.

AB - The magnetic field structures of two interplanetary coronal mass ejections (ICMEs), each observed by a pair of spacecraft close to radial alignment, have been analysed. The ICMEs were observed in situ by MESSENGER and STEREO-B in November 2010 and November 2011, while the spacecraft were separated by more than 0.6 AU in heliocentric distance, less than 4 degrees in heliographic longitude, and less than 7 degrees in heliographic latitude. Both ICMEs took approximately two days to travel between the spacecraft. The ICME magnetic field profiles observed at MESSENGER have been mapped to the heliocentric distance of STEREO-B and compared directly to the profiles observed by STEREO-B. Figures that result from this mapping allow for easy qualitative assessment of similarity in the profiles. Macroscale features in the profiles that varied on timescales of one hour, and which corresponded to the underlying flux rope structure of the ICMEs, were well correlated in the solar east-west and north-south directed components, with Pearson's correlation coefficients of approximately 0.85 and 0.95, respectively; microscale features with timescales of one minute were uncorrelated. Overall correlation values in the profiles of one ICME were increased when an apparent change in the flux rope axis direction between the observing spacecraft was taken into account. The high degree of similarity seen in the magnetic field profiles may be interpreted in two ways. If the spacecraft sampled the same region of each ICME (i.e. if the spacecraft angular separations are neglected), the similarity indicates that there was little evolution in the underlying structure of the sampled region during propagation. Alternatively, if the spacecraft observed different, nearby regions within the ICMEs, it indicates that there was spatial homogeneity across those different regions. The field structure similarity observed in these ICMEs points to the value of placing in situ space weather monitors well upstream of the Earth.

AB - We report herein a method for intermolecular [3 + 2] cycloaddition between aryl cyclopropyl ketones and alkenes involving the combination of Lewis acid and photoredox catalysis. In contrast to other more common methods for [3 + 2] cycloaddition, these conditions operate using a broad range of both electron-rich and electron-deficient reaction partners. The critical factors predicting the success of these reactions is the redox potential of the cyclopropyl ketone and the ability of the alkene to stabilize a key radical intermediate.

AB - Volcanic systems are comprised of a complex combination of ongoing eruptive activity and secondary hazards, such as remobilized ash plumes. Similarities in the visual characteristics of remobilized and erupted plumes, as imaged by satellite-based remote sensing, complicate the accurate classification of these events. The stereo imaging capabilities of the Multi-angle Imaging SpectroRadiometer (MISR) were used to determine the altitude and distribution of suspended particles. Remobilized ash shows distinct dispersion, with particles distributed within ~1.5 km of the surface. Particle transport is consistently constrained by local topography, limiting dispersion pathways downwind. The MISR Research Aerosol (RA) retrieval algorithm was used to assess plume particle microphysical properties. Remobilized ash plumes displayed a dominance of large particles with consistent absorption and angularity properties, distinct from emitted plumes. The combination of vertical distribution, topographic control, and particle microphysical properties makes it possible to distinguish remobilized ash flows from eruptive plumes, globally. PMID- 29568142 TI - Differences in Sexual Behavior of Teenagers and Young Adults with Cerebral Palsy: The Role of Sexual Needs and Sexual Esteem. AB - Sexuality is an inherent attribute of all human beings regardless of their race, religion and the level of physical fitness. The way it is perceived and manifested is determined by a number of biopsychosocial factors. In some people, including persons with cerebral palsy, the factors and their influence are rooted in the psychophysical condition of the human body. The aim of this study was to answer the question about how the levels of sexual esteem and sexual needs differentiate the sexual behaviors of young people with cerebral palsy. The study being presented was conducted with 62 young persons with cerebral palsy (half women and half men), who were selected using purposive sampling. They were aged 15-25 years and were individuals without cognitive difficulties. The research tool used was the Cerebral Palsy Individual's Sexual Behavior Questionnaire developed by the authors. The findings of the study showed that half of the participants engaged in various sexual behaviors from the list that was presented to them. The frequencies of these engagements depended on the levels of their sexual esteem and sexual needs. Persons characterized by high levels of sexual esteem and sexual needs (much fewer than those with the low levels of both characteristics) engaged in sexual behaviors significantly more frequently. The most frequent among them was direct engagement in sexual activity (petting and sexual intercourse; p <= .001) and then exposure to sexually explicit magazines or films (p <= .05).

PMID- 29568144 TI - Youth Disclosure of Sexual Orientation to Siblings and Extended Family. AB - Objective: To explore the processes and experiences associated with disclosing sexual orientation to siblings and extended family. Background: Few studies prioritize the experience of disclosing to siblings and extended family, despite its frequency and potential impact on the family unit. Extended family members often act as sources of support for youth; it is therefore worthwhile to consider whether this remains true during and after disclosure of sexual orientation. Method: Interview and questionnaire data were gathered from 22 lesbian, gay, bisexual, and queer (LGBQ) youth, 14 to 21 years of age, from a large Midwestern city. Constructivist grounded theory informed the qualitative methodology and data analysis. We build on concepts of horizontal and vertical family relationships by also introducing the concept of diagonal relationships. Results: Participants described their relationships with aunts as possessing characteristics of horizontal and vertical relationships, allowing them to act as moderators and mediators of the parent-child relationship. Conclusion: The concepts of vertical, horizontal, and diagonal relationships take into consideration how the structure (e.g., hierarchy, egalitarianism, boundaries) and nature (e.g., closeness, reciprocity, mentorship) of various relationships shape the coming-out process for LGBQ youth, without dismissing the importance of either immediate or extended family members. Implications: The emerging conceptualization can guide services and interventions as well as illuminate further research on the family systems of LGBQ youth. PMID- 29568145 TI - The impact of parenthood on environmental attitudes and behaviour: a longitudinal investigation of the legacy hypothesis. AB - Willingness to engage in sustainable actions may be limited by the psychological distance of climate change. In this study, we test the legacy hypothesis, which holds that having children leads parents to consider the legacy left to offspring in respect of environmental quality. Using the Understanding Society dataset, a longitudinal survey representative of the UK population (n = 18,176), we assess how having children may change people's individual environmental attitudes and behaviour. Results indicate that having a new child is associated with a small decrease in the frequency of a few environmental behaviours. Only parents with already high environmental concern show a small increase in the desire to act more sustainably after the birth of their first child. Overall, the results do not provide evidence in support of the legacy hypothesis in terms of individual level environmental attitudes and behaviours. We argue that the transition to parenthood is a time where concern is prioritised on the immediate wellbeing of the child and not on the future environmental threats.

AB - Intravascular Optical Coherence Tomography (IVOCT) is a high contrast, 3D microscopic imaging technique that can be used to assess atherosclerosis and guide stent interventions. Despite its advantages, IVOCT image interpretation is challenging and time consuming with over 500 image frames generated in a single pullback volume. We have developed a method to classify voxel plaque types in IVOCT images using machine learning. To train and test the classifier, we have used our unique database of labeled cadaver vessel IVOCT images accurately registered to gold standard cryo-images. This database currently contains 300 images and is growing. Each voxel is labeled as fibrotic, lipid-rich, calcified or other. Optical attenuation, intensity and texture features were extracted for each voxel and were used to build a decision tree classifier for multi-class classification. Five-fold cross-validation across images gave accuracies of 96 % +/- 0.01 %, 90 +/- 0.02% and 90 % +/- 0.01 % for fibrotic, lipid-rich and calcified classes respectively. To rectify performance degradation seen in left out vessel specimens as opposed to left out images, we are adding data and reducing features to limit overfitting. Following spatial noise cleaning, important vascular regions were unambiguous in display. We developed displays that enable physicians to make rapid determination of calcified and lipid regions. This will inform treatment decisions such as the need for devices (e.g., atherectomy or scoring balloon in the case of calcifications) or extended stent lengths to ensure coverage of lipid regions prone to injury at the edge of a stent. PMID- 29568147 TI - Comparison of quantitative myocardial perfusion imaging CT to fluorescent microsphere-based flow from high-resolution cryo-images. AB - Myocardial perfusion imaging using CT (MPI-CT) has the potential to provide quantitative measures of myocardial blood flow (MBF) which can aid the diagnosis of coronary artery disease. We evaluated the quantitative accuracy of MPI-CT in a porcine model of balloon-induced LAD coronary artery ischemia guided by fractional flow reserve (FFR). We quantified MBF at baseline (FFR=1.0) and under moderate ischemia (FFR=0.7) using MPI-CT and compared to fluorescent microsphere based MBF from high-resolution cryo-images. Dynamic, contrast-enhanced CT images were obtained using a spectral detector CT (Philips Healthcare). Projection-based mono-energetic images were reconstructed and processed to obtain MBF. Three MBF quantification approaches were evaluated: singular value decomposition (SVD) with fixed Tikhonov regularization (ThSVD), SVD with regularization determined by the L-Curve criterion (LSVD), and Johnson-Wilson parameter estimation (JW). The three approaches over-estimated MBF compared to cryo-images. JW produced the most accurate MBF, with average error 33.3+/-19.2mL/min/100g, whereas LSVD and ThSVD had greater over-estimation, 59.5+/-28.3mL/min/100g and 78.3+/-25.6 mL/min/100g, respectively. Relative blood flow as assessed by a flow ratio of LAD-to-remote myocardium was strongly correlated between JW and cryo-imaging, with R2=0.97, compared to R2=0.88 and 0.78 for LSVD and ThSVD, respectively. We assessed tissue impulse response functions (IRFs) from each approach for sources of error. While JW was constrained to physiologic solutions, both LSVD and ThSVD produced IRFs with non-physiologic properties due to noise. The L-curve provided noise-adaptive regularization but did not eliminate non-physiologic IRF properties or optimize for MBF accuracy. These findings suggest that model-based MPI-CT approaches may be more appropriate for quantitative MBF estimation and that cryo-imaging can support the development of MPI-CT by providing spatial distributions of MBF.

AB - There is growing recognition of the contribution of wild foods to local diets, nutrition, and culture. Yet disaggregation of understanding of wild food use by gender and age is limited. We used a mixed methods approach to determine the types, frequencies, and perceptions of wild foods used and sold by children in four villages in southern Malawi that have different levels of deforestation. Household and individual dietary diversity scores are low at all sites. All households consume one or more wild foods. Across the four sites, children listed 119 wild foods, with a wider variety at the least deforested sites than the most deforested ones. Older children can name more wild foods than younger ones. More children from poor households sell wild foods than from well-off households. Several reasons were provided for the consumption or avoidance of wild foods (most commonly taste, contribution to health, limited alternatives, hunger, availability, local taboos). PMID- 29568149 TI - What makes Alpine swift ascend at twilight? Novel geolocators reveal year-round flight behaviour. AB - Abstract: Studying individual flight behaviour throughout the year is indispensable to understand the ecology of a bird species. Recent development in technology allows now to track flight behaviour of small long-distance bird migrants throughout its annual cycle. The specific flight behaviour of twilight ascents in birds has been documented in a few studies, but only during a short period of the year, and never quantified on the individual level. It has been suggested that twilight ascents might be a role in orientation and navigation. Previous studies had reported the behaviour only near the breeding site and during migration. We investigated year-round flight behaviour of 34 individual Alpine swifts (Apus melba) of four different populations in relation to twilight ascents. We recorded twilight ascents all around the year and found a twofold higher frequency in ascents during the non-breeding residence phase in Africa compared to all other phases of the year. Dawn ascents were twice as common as dusk ascents and occurred mainly when atmospheric conditions remained stable over a 24-h period. We found no conclusive support that twilight ascents are essential for recalibration of compass cues and landmarks. Data on the wing flapping intensity revealed that high activity at twilight occurred more regularly than the ascents. We therefore conclude that alpine swift generally increase flight activity-also horizontal flight-during the twilight period and we suppose that this increased flight activity, including ascents, might be part of social interactions between individuals. Significance statement: Year-round flight altitude tracking with a light-weight multi-sensor tag reveals that Alpine swifts ascend several hundred meters high at twilight regularly. The reason for this behaviour remains unclear and the low-light conditions at this time of the day preclude foraging as a possibility. The frequency and altitude of twilight ascents were highest during the non-breeding period, intermediate during migration and low for active breeders during the breeding phase. We discuss our findings in the context of existing hypotheses on twilight ascent and we propose an additional hypothesis which links twilight ascent with social interaction between flock members. Our study highlights how flight behaviour of individuals of a migratory bird species can be studied even during the sparsely documented non-breeding period.

AB - Abstract: Eusociality is characterised by a reproductive division of labour, where some individuals forgo direct reproduction to instead help raise kin. Socially polymorphic sweat bees are ideal models for addressing the mechanisms underlying the transition from solitary living to eusociality, because different individuals in the same species can express either eusocial or solitary behaviour. A key question is whether alternative social phenotypes represent environmentally induced plasticity or predominantly genetic differentiation between populations. In this paper, we focus on the sweat bee Lasioglossum calceatum, in which northern or high-altitude populations are solitary, whereas more southern or low-altitude populations are typically eusocial. To test whether social phenotype responds to local environmental cues, we transplanted adult females from a solitary, northern population, to a southern site where native bees are typically eusocial. Nearly all native nests were eusocial, with foundresses producing small first brood (B1) females that became workers. In contrast, nine out of ten nests initiated by transplanted bees were solitary, producing female offspring that were the same size as the foundress and entered directly into hibernation. Only one of these ten nests became eusocial. Social phenotype was unlikely to be related to temperature experienced by nest foundresses when provisioning B1 offspring, or by B1 emergence time, both previously implicated in social plasticity seen in two other socially polymorphic sweat bees. Our results suggest that social polymorphism in L. calceatum predominantly reflects genetic differentiation between populations, and that plasticity is in the process of being lost by bees in northern populations. Significance statement: Phenotypic plasticity is thought to play a key role in the early stages of the transition from solitary to eusocial behaviour, but may then be lost if environmental conditions become less variable. Socially polymorphic sweat bees exhibit either solitary or eusocial behaviour in different geographic populations, depending on the length of the nesting season. We tested for plasticity in the socially polymorphic sweat bee Lasioglossum calceatum by transplanting nest foundresses from a northern, non-eusocial population to a southern, eusocial population. Plasticity would be detected if transplanted bees exhibited eusocial behaviour. We found that while native bees were eusocial, 90% of transplanted bees and their offspring did not exhibit traits associated with eusociality. Environmental variables such as time of offspring emergence or temperatures experienced by foundresses during provisioning could not explain these differences. Our results suggest that the ability of transplanted bees to express eusociality is being lost, and that social polymorphism predominantly reflects genetic differences between populations. PMID- 29568151 TI - Continuous laccase concentration in an aqueous two-phase system. AB - An approach to describe continuous partitioning of Cerrena unicolor laccase in a PEG 6000-phosphate aqueous two-phase system was proposed. The laccase was separated from crude supernatant of C. unicolor-submerged culture, and all the experiments were carried out in 25 degrees C and pH 7 conditions. Masses of both phases and their compositions at phase equilibrium, as well as laccase activity concentrations at different mixing points, were measured in batch experiments. An empirical short-cut method was developed which allows for calculation of mass and volume fractions of the phases, laccase concentration factors, and laccase recoveries. Theoretical predictions were verified by several experiments carried out in a special mixer-settler unit with automatic substrate feed and continuous collection of separated phases. Required concentration of the laccase was possible to achieve in a one-step extraction process in the mixer-settler unit. The predictions of the short-cut method were compared to the results of experimental measurements of phase compositions, phase volume fractions, concentration factors and enzymatic yields at steady-state operation of the extraction unit. The values of experimental results lay well within the 10% error range of the predicted values.

AB - The paper presents results of an experimental study of the fluid velocity field in a stirred tank equipped with a Prochem Maxflo T (PMT) type impeller which was rotating at a constant frequency of N = 4.1 or 8.2 s-1 inducing transitional (Re = 499 or 1307) or turbulent (Re = 2.43 * 104) flow of the fluid. The experiments were performed for a Newtonian fluid (water) and a non-Newtonian fluid (0.2 wt% aqueous solution of carboxymethyl cellulose, CMC) exhibiting mild viscoelastic properties. Measurements were carried out using laser light scattering on tracer particles which follow the flow (2-D PIV). For both the water and the CMC solution one primary and two secondary circulation loops were observed within the fluid volume; however, the secondary loops were characterized by much lower intensity. The applied PMT-type impeller produced in the Newtonian fluid an axial primary flow, whilst in the non-Newtonian fluid the flow was more radial. The results obtained in the form of the local mean velocity components were in satisfactory agreement with the literature data from LDA. Distribution of the shear rate in the studied system was also analyzed. For the non-Newtonian fluid an area was computed where the elastic force dominates over the viscous one. The area was nearly matching the region occupied by the primary circulation loop.

AB - Abstract: The 7H-indolo[1,2-a]quinolinium merocyanine was applied as a new water sensor in organic solvents such as ethanol, propane-1-ol, propane-2-ol, DMSO, and DMF. The spectral changes of the dye caused by the addition of increasing amount of water into an organic solvent were investigated. Based on the results, the calibration curves were found as a relation between the position of the absorption band of the dye and the water concentration ranging from about 0.05 to 11% (w/w). In case of ethanol, propane-1-ol and propane-2-ol the plots were linear, whereas in DMSO and DMF, better results were obtained with the use of a polynomial function. The method allowed to determine the water content in a fast and precise manner.

AB - Influence of elevated CO2 (570 +/- 25 ppm) and elevated temperature (?3 degrees C higher than ambient) on rice (Oryzasativa L.) and brown planthopper (BPH), Nilaparvata lugens (Stal.) was studied in open top chambers during rainy season of 2013. Elevated CO2 and temperature exhibited positive effect on BPH multiplication thus enhancing its population (55.2 +/- 5.7 hoppers/hill) in comparison to ambient CO2 and temperature (25.5 +/- 2.1 hoppers/hill). Elevated CO2 + temperature significantly reduced the adult longevity and nymphal duration by 17.4 and 18.5 % respectively, however elevated conditions increased BPH fecundity by 29.5 %. In rice crop, interactive effect of elevated CO2 and temperature led to an increase in the number of tillers (20.1 %) and canopy circumference (30.4 %), but resulted in a decrease of reproductive tillers (10.8 %), seeds/panicle (10.9 %) and 1000-seed weight (8.6 %) thereby reducing grain yield (9.8 %). Moreover, positive effect of increased CO2 concentration and temperature on BPH population exacerbates the damage (30.6) which in turn coupled with the plant traits to hampering production.

AB - The present study describes the relationship between the morphology of the forewing axillary sclerites and the way the wings fold among 24 aphid genera as compared to a representative of coccids. Architecture of the forewing base was imaged with scanning electron and optical (fluorescence) microscopy. Significant differences in morphology of axillary sclerites between aphid species were observed, despite their belonging to one infraorder. Detailed description of 41 features of axillary sclerites was made. There was no difference between axillaries of viviparous (Aphididae) and oviparous (Adelges sp., Phylloxera sp.) species. No clear relationship between morphology of the axillary sclerites and the wing folding could be confirmed. Instead, the thorax structure determines the way the wing folds in aphids. Phylogenetic analysis based on our results cannot be conducted at this stage of study. To show how three-dimensional the structures are and how difficult to describe, a short animation of Aphis fabae (Aphididae) wing base was added. This is a preliminary study about morphology of axillary sclerites among aphids. PMID- 29568156 TI - Elytra reduction may affect the evolution of beetle hind wings. AB - Beetles are one of the largest and most diverse groups of animals in the world. Conversion of forewings into hardened shields is perceived as a key adaptation that has greatly supported the evolutionary success of this taxa. Beetle elytra play an essential role: they minimize the influence of unfavorable external factors and protect insects against predators. Therefore, it is particularly interesting why some beetles have reduced their shields. This rare phenomenon is called brachelytry and its evolution and implications remain largely unexplored. In this paper, we focused on rare group of brachelytrous beetles with exposed hind wings. We have investigated whether the elytra loss in different beetle taxa is accompanied with the hind wing shape modification, and whether these changes are similar among unrelated beetle taxa. We found that hind wings shape differ markedly between related brachelytrous and macroelytrous beetles. Moreover, we revealed that modifications of hind wings have followed similar patterns and resulted in homoplasy in this trait among some unrelated groups of wing-exposed brachelytrous beetles. Our results suggest that elytra reduction may affect the evolution of beetle hind wings. PMID- 29568157 TI - Light Regulates the RUBylation Levels of Individual Cullin Proteins in Arabidopsis thaliana. AB - In plants, the small protein related to ubiquitin (RUB) modifies cullin (CUL) proteins in ubiquitin E3 ligases to allow for efficient transfer of ubiquitin to substrate proteins for degradation by the 26S proteasome. At the molecular level, the conjugation of RUB to individual CUL proteins is transient in nature, which aids in the stability of the cullins and adaptor proteins. Many changes in cellular processes occur within the plant upon exposure to light, including well documented changes in the stability of individual proteins. However, overall activity of E3 ligases between dark- and light-grown seedlings has not been assessed in plants. In order to understand more about the activity of the protein degradation pathway, overall levels of RUB-modified CULs were measured in Arabidopsis thaliana seedlings growing in different light conditions. We found that light influenced the global levels of RUBylation on CULs, but not uniformly. Blue light had little effect on both Cul1 and Cul3 RUBylation levels. However, red light directed the increase in Cul3 RUBylation levels, but not Cul1. This red light regulation of Cul3 was at least partially dependent on the activation of the phytochrome B signaling pathway. The results indicate that the RUBylation levels on individual CULs change in response to different light conditions, which enable plants to fine-tune their growth and development to the various light environments.

AB - Herein, we present the design, synthesis, and characterization of fully degradable, hybrid, star-branched dendritic polyols. First multiarmed polyphosphazenes were prepared as a star-branched scaffold which upon functionalization produced globular branched hydroxyl-functionalized polymers with over 1700 peripheral functional end groups. These polyols with unique branched architectures could be prepared with controlled molecular weights and relatively narrow dispersities. Furthermore, the polymers are shown to undergo hydrolytic degradation to low molecular weight degradation products, the rate of which could be controlled through postpolymerization functionalization of the phosphazene backbone. PMID- 29568159 TI - Exploring the Relationship Balance Assessment. AB - Assessments of power in couples' relationships often only survey one partner, but they do not take into consideration both partners' perceptions. Thus, many assumptions about power and equality in relationships have not been quantitatively tested due to a lack of dyadic measures of power. Therefore, the purpose of the Gender and Relationships Study was to develop and test a new scale of equality and relative power for couples, the Relationship Balance Assessment (RBA). The RBA may be useful for research and for clinical work with couples to help raise awareness of the balance of power in their relationship. A review of the literature has shown a shift away from focusing on monetary resources and decision-making dominance towards examining relationship processes and the connection between gender and power. This study prescreened a pool of process oriented questions based on the qualitative literature. Then exploratory factor analysis of data from 268 individuals and 91 couples identified 12 consistent latent factors underlying relationship equality. These 12 subscales are summed up with the TREASURES acronym: Time Discretion, Relational Power, Emotional Power (Emotional Expression and Avoidance subscales), Accommodation, Spending and Saving subscales, Union or Sexual Dominance, Rational Power, Economic Role Power (Status and Childcare subscales), and Social Choices. PMID- 29568160 TI - Learning About Parenting Together: A Programme to Support Parents with Inter generational Concerns in Pune, India. AB - Rapid developments in the last few decades have brought about dramatic changes in Indian social life, particularly affecting new middle-class families. Inter generational conflicts, high academic pressures, and modern anxieties lead to stress both in parents and in children. There is a need for parenting programmes that respond to these specific concerns, in order to reduce parenting stress and improve family well-being. This study aimed to develop and evaluate a parenting programme in Pune, India, based on a 'theory of change'. In this pilot programme, parents were encouraged to learn in a group format about fostering autonomy in children, promoting academic potential in a stress-free manner and remaining in connection with adolescents. Facilitated by a psychologist, parents participated in four sessions involving 'creativity and play', 'self-awareness and bonding', and 'communication'. The intervention was based on validated psychotherapeutic approaches and parenting methods to support parents in their learning. Some 16 in depth interviews were conducted with parents before and eight interviews after the intervention to understand their learning experiences. Additional feedback was gathered from observation notes and debriefings after each session. The results show that the attention for playful quality time helped parents to (re)gain a more creative and flexible attitude towards spending time with their children. Second, parents learned to reflect on their frameworks of meaning (rooted in their own upbringing), listen attentively and communicate more mindful with their children. Furthermore, this study shows that an activity-based approach, connecting parents in co-creating new parenting paradigms, while supporting them with stress-reducing tools, is a useful way of engaging this target group. The study concludes by offering new perspectives for counsellors working with families in countries undergoing rapid change.

AB - In this article I present our experience at the Magnet Technology Division of the MIT Francis Bitter Magnet Laboratory on liquid-helium (LHe)-free, persistent-mode MgB2 MRI magnets. Before reporting on our MgB2 magnets, I first summarize the basic work that we began in the late 1990s to develop LHe-free, high-temperature superconductor (HTS) magnets cooled in solid cryogen-I begin by discussing the enabling feature, particularly of solid nitrogen (SN2), for adiabatic HTS magnets. The next topic is our first LHe-free, SN2-HTS magnet, for which we chose Bi2223 because in the late 1990s Bi2223 was the only HTS available to build an HTS magnet. I then move on to two MgB2 magnets, I and II, developed after discovery of MgB2 in 2000. The SN2-MgB2 Magnet II-0.5-T/240-mm, SN2-cooled, and operated in persistent mode-was completed in January 2016. The final major topic in this article is a tabletop LHe-free, persistent-mode 1.5-T/70-mm SN2-MgB2 "finger" MRI magnet for osteoporosis screening-we expect to begin this project in 2017. Before concluding this article, I present my current view on challenges and prospects for MgB2 MRI magnets. PMID- 29568162 TI - The transitional dynamics of caloric ecosystems: changes in the food supply around the world. AB - Changes to the global food supply have been characterized by greater availability of edible oils, sweeteners, and meats-a profound "nutrition transition" associated with rising obesity, type 2 diabetes, and cardiovascular disease. Through an analysis of three longitudinal databases of food supply, sales and economics across the period 1961-2010, we observed that the change in global food supply has been characterized by a dramatic rise in pig meat consumption in China and poultry consumption in North America. These changes have not been experienced by all rapidly-developing countries, and are not well explained by changes in income. The changes in food supply include divergence among otherwise similar neighboring countries, suggesting that the changes in food supply are not an inevitable result of economic development. Furthermore, we observed that the nutrition transition does not merely involve an adoption of "Western" diets universally, but can also include an increase in the supply of edible oils that are uncommon in Western countries. Much of the increase in sales of sugar sweetened beverages and packaged foods is attributable to a handful of multinational corporations, but typically from products distributed through domestic production systems rather than foreign importation. While North America and Latin America continued to have high sugar-sweetened beverage and packaged food sales in recent years, Eastern Europe and the Middle East have become emerging markets for these products. These findings suggest further study of natural experiments to identify which policies may mitigate nutritional risk factors for chronic disease in the context of economic development.

PMID- 29568166 TI - Expression of protease-activated receptors 1 and 2 in individuals with healthy gingiva and chronic periodontitis. AB - Background: Protease-activated receptors (PAR-1 and PAR-2) are found to be immensely exhibited in the periodontal tissues. These receptors are involved in the inflammatory and repair processes. Activation of PARs is mainly by the bacterial and endogenous enzymes. The aim of the study was to determine the role of PAR-1 and PAR-2 in initiating periodontal inflammation and to immunolocalize these receptors in the gingival tissues of healthy and chronic periodontitis individuals. Materials and Methods: A total of 50 patients were selected for this study, of which 25 were healthy controls and 25 were chronic periodontitis patients. Gingival tissues were excised from the marginal gingiva and interdental papilla under local anesthesia (xylocaine with 2% adrenaline) during crown lengthening procedure or during periodontal therapy depending on the respective groups. Immunohistochemical analyses of PARs were done by staining the samples with hematoxylin and eosin and with primary and secondary antibody for PAR-1 and PAR-2. Results: The Hematoxylin and Eosin staining showed more inflammatory changes in the periodontitis group compared to healthy gingiva. In chronic periodontitis, PAR-1-positive cells were seen in the basal layer with a weak expression and were showing negative expression in the superficial layer. In consideration of PAR-2, there was a very strong expression up to the superficial layer of the epithelium, compared to PAR-1. On comparing the intensity of staining in the connective tissue of chronic periodontitis sample, there was an increased expression of PAR-2 compared with PAR-1. A low positive expression of PAR-1 and PAR-2 was observed in the epithelium and connective tissue of the healthy tissues. Conclusion: The results clearly demonstrated the role of PAR-1 and 2 in periodontal inflammation. PMID- 29568165 TI - Periodontal microsurgery: Reaching new heights of precision. AB - The use of magnification to perform various procedures in medical and dental field, particularly endodontics has long been recognized. Unfortunately, its application in periodontics is not widely popularized. The objective of this article is to emphasize the application of microsurgical principles in various periodontal surgical procedures and to reinforce the incorporation of microscope into periodontal practice. The most recent periodontal journals were reviewed and a search of databases such as PubMed or Medline and Google Scholar was conducted for relevant material from published literature up to 2017. Medical Subject Headings words looked for were "periodontal microsurgery" and "minimally invasive periodontal surgery." The available literature, specifically to periodontal surgical procedures was analyzed and compiled. The analysis indicates that incorporation of magnification in periodontal practice is associated with improved visual acuity, ergonomic benefits, decreased patient morbidity, rapid healing, and enhanced patient acceptance. PMID- 29568167 TI - Efficiency of three different polishing methods on enamel and cementum: A scanning electron microscope study. AB - Background: Tooth polishing is an integral part of clinical dentistry. The main purpose of polishing is to smoothen the surface of the tooth and minimize the deposition of plaque to allow a healthy periodontal maintenance postscaling. Today, polishing by different methods is available to a clinician. Traditional bristle brush and rubber-cup polishing are being widely practiced and gradually getting replaced by novel air polisher. Pros and cons of each method should be weighed before its clinical applications. Aim and Objectives: To evaluate and compare the efficiency of three different polishing systems on enamel as well as on cementum surfaces by scanning electron microscope (SEM). Materials and Methods: A total of 120 samples were divided into three groups randomly - Group 1 (bristle brush), Group 2 (rubber cup), and Group 3 (air polisher) - with 20 samples each of enamel and cementum, which were subdivided into 10 control and 10 test group (subjected to polishing). The samples were analyzed by SEM at *1000 magnification, and the data obtained were compiled and subjected to statistical analysis. Results: Polishing with bristle brush demonstrated less surface roughness and debris when compared to air polisher at P = 0.58, P = 0.03 for enamel surface and P = 0.003, P = 0.21 for cementum, respectively. The surface roughness was reduced considerably by rubber cup at P = 0.03 for enamel and P = 0.003 for cementum, compared to air polisher at P = 0.99 and P = 0.21 for enamel and cementum, respectively. Conclusion: The results indicate that polishing with rubber cup was more effective and statistically significant when compared to bristle brush polishing and air polisher for the crown and root surface smoothening and debris removal. PMID- 29568168 TI - Periostin levels in saliva of patients with chronic periodontitis. AB - Background: Periostin acts as a necessary protein for tissue integrity and maturity and has a key role as a modulator of periodontal ligament hemostasis. It has been shown that periostin acts as a supportive protein. The aim of this study was to compare the concentration of periostin in the saliva of patients with chronic periodontitis and healthy controls. Materials and Methods: In this case control, cross-sectional study, a total of 45 individuals (25 patients with chronic periodontitis and 20 healthy controls) were evaluated. Whole saliva samples were collected, and periostin levels were evaluated by standard enzyme linked immunosorbent assay. The results were analyzed by SPSS and Mann-Whitney analysis. Results: The results of this study showed that the level of periostin in saliva in patients with periodontitis was significantly lower than healthy controls (P < 0.05). Periostin was detectable in all samples. Conclusion: The results show that there is a significant relationship between the level of periostin in saliva and chronic periodontitis. Periostin may be considered as an inflammatory marker in periodontal disease. However, further studies are needed to confirm this finding. PMID- 29568169 TI - Efficacy of Ayurvedic drugs as compared to chlorhexidine in management of chronic periodontitis: A randomized controlled clinical study. AB - Background: In India, Ayurveda is considered to be more effective and cheaper than modern medicine. Ayurvedic literature shows its use in treating oral diseases also. However, their effectiveness, in comparison with the allopathic mode of management, has not been assessed previously. The aim of this randomized controlled clinical trial was to compare the efficacy of ayurvedic drugs over chlorhexidine in treating chronic periodontitis. Materials and Methods: Four hundred and eight participants, in the age group 20-49 years, suffering from mild to-moderate chronic periodontitis were included in this study. Community periodontal index for treatment needs (CPITN) score was recorded, and oral prophylaxis was done for each patient. They were then randomly divided into 6 groups: control group (I), chlorhexidine (II), Khadiradi vati (III), Dashansanskar churana (IV), Neem (V), and Apamarga (VI); based on the drugs used by patients for the maintenance of oral hygiene after oral prophylaxis. Patients were recalled at 1 week, 1 month, and 3 months after oral prophylaxis. CPITN score was re-recorded for each patient at each follow-up. Reduction in CPITN score indicated improvement in the periodontal health. Observations were statistically analyzed using univariate ANOVA and P value was set at <0.5. Results: Improvement in CPITN scores in 6 groups was as follows: I - 42.0%, II - 76.37%, III - 82.03%, IV - 83.46%, V - 78.8%, and VI - 29.9%. Higher mean percentage improvement was seen when patients used these drugs for 3 months as compared to 1 month. Conclusion: Dashansanskar churana and Khadiradi vati showed better results than chlorhexidine and were found to be superior in managing mild to-moderate cases of chronic periodontitis. PMID- 29568170 TI - Effectiveness of three mouthwashes - Manuka honey, Raw honey, and Chlorhexidine on plaque and gingival scores of 12-15-year-old school children: A randomized controlled field trial. AB - Objectives: The aim of this study is to compare the effectiveness of three types of mouthwashes manuka honey (MH), raw honey (RH), and chlorhexidine (CHX) on plaque and gingival scores of 12-15-year-old government school children. Study Design: This study was a double-blind, randomized controlled field trial conducted in Belagavi city, India. Materials and Methods: One hundred and thirty five government school children aged 12-15 years were randomly selected and allocated into three groups, RH, MH, and CHX mouthwash groups. Ten milliliters each of honey-based mouthwash formulation and CHX mouthwashes (0.2%) were administered according to the group allocation twice daily for 21 days. All the children were examined at baseline, 22nd day (after discontinuation of mouthwash) and 28th day (1 week after discontinuation of mouthwash) for Gingival (Loe and silness 1963) and Plaque Index (Silness and Loe, 1964). Results: Descriptive statistics was applied for distribution of study participants according to age and gender. One-way ANOVA followed by Tukey's post hoc test and repeated measures ANOVA test followed by Bonferroni's post hoc were applied for inter- and intragroup comparison, respectively. Statistically significant reductions (P < 0.001) in plaque and gingival scores were observed in all the three types of mouthwash groups at the end of the 22nd day and 28th day. MH and RH mouthwash demonstrated equal effectiveness, whereas CHX mouthwash showed the maximum reduction in clinical parameters. Conclusion: Honey-based mouthwash showed a promising antimicrobial effect on dental caries and plaque and gingival scores. PMID- 29568171 TI - Effect of scaling and root planing on gingival crevicular fluid level of YKL-40 acute phase protein in chronic periodontitis patients with or without type 2 diabetes mellitus: A clinico-biochemical study. AB - Background: The aim of the present study was to evaluate the gingival crevicular fluid (GCF) levels of YKL-40 acute phase protein in chronic periodontitis (CP) with and without type 2 diabetes and also to assess the effect of periodontal therapy (scaling and root planing [SRP]) on this GCF biomarker and the clinical parameters. YKL-40 is derived from tyrosine (Y), lysine (K), and leucine (L) with a molecular weight of 40 kDa. Materials and Methods: A total of 105 individuals (30-60 years) were grouped as 35 individuals each in three groups (Group I - healthy; Group II - CP with diabetes mellitus [DM]; and Group III - CP). Clinical parameters including plaque index, gingival index, probing pocket depth, and clinical attachment level followed by GCF sample collection from test sites were done at baseline and 6 weeks after SRP (among Group II and Group III patients). GCF YKL-40 level was determined by enzyme-linked immunosorbent assay. Results: The mean GCF YKL-40 level at baseline was significantly lower for Group I (309.81 +/- 124.93 pg/ml) as compared to Group II (924.88 +/- 415.28 pg/ml) and Group III (834.08 +/- 270.42 pg/ml), respectively (P < 0.001). The level reduced significantly 6 weeks after SRP for Group II (507.6 +/- 265.03 pg/ml) and Group III (499.54 +/- 293.38 pg/ml) (P < 0.001). Conclusion: The level of GCF YKL-40 in CP patients with or without DM is higher than healthy individuals and the level reduced 6 weeks post-SRP among Group II and Group III. Hence, YKL-40 can be considered as an important biomarker in the diagnosis of CP. PMID- 29568172 TI - Treatment of gingival recession by coronally advanced flap in conjunction with platelet-rich fibrin or resin-modified glass-ionomer restoration: A clinical study. AB - Aims: The aim of this study is to compare the outcome of coronally advanced flap (CAF) along with the use of platelet-rich fibrin (PRF) versus CAF in conjunction with a resin-modified glass-ionomer cement (RmGIC) for the management of Millers Class I and Class II gingival recession coupled with noncarious cervical lesions (NCCLs). Materials and Methods: Single and multiple Miller's Class I and Class II gingival recessions were chosen for the study. Twenty participants with total of 78 sites associated with NCCL bilaterally in the anterior and premolar region of maxilla were selected. Thirty-nine sites were treated with CAF and PRF and the remaining 39 sites were treated with CAF and RmGIC. Clinical parameters such as probing pocket depth, relative gingival recession, relative clinical attachment level, NCCL height, NCCL width, width of keratinized tissue, and keratinized tissue thickness were measured at baseline, 90th, and 180th day in both the groups. The presence or absence of dentin sensitivity (DS) was determined at baseline and 180th day. Results: Both the groups showed optimal root coverage, with statistical significant difference in thickness of keratinized gingiva in Group I when compared to Group II from baseline to 90th day and from baseline to 180th day and also from 90th to 180th day. On comparing the DS between Group I and Group II from baseline to 180th day, Group II showed greater reduction in dentinal hypersensitivity as compared to Group I. Conclusion: The use of PRF along with CAF showed increased thickness of the keratinized tissue and the utilization of RmGIC resulted in decreased DS. Hence, the combination of CAF and PRF or CAF and RmGIC could provide a better treatment option in the management of gingival recession that is of esthetic concern. PMID- 29568173 TI - Maternal periodontal disease and preeclampsia in Jaipur population. AB - Background: Preeclampsia is identified as an important cause for mother and newborn mortality. Inspite of extensive research, the exact etiological relations have not been established. Hence, an attempt has been made in this study to evaluate the relationship between the preeclampsia and maternal periodontal disease. Materials and Methods: The case-control study comprised of thirty pregnant women distributed equally in the case (preeclampsia) and control (healthy) group. Gingival index, plaque index, bleeding on probing, clinical probing depth, and clinical attachment level were measured in both groups. Microbiologic examination for identification of one red complex organism Porphyromonas gingivalis and one orange complex organism Fusobacterium nucleatum were done in plaque and placental blood of cases and controls. The clinical examinations and collection of placental blood were done 24 h before delivery. Results: Periodontal condition in the preeclamptic women was statistically worse compared with the normotensive women. There was no statistically significant association between microorganisms in plaque and placental blood between normotensive control and preeclamptic pregnant women. The preeclamptic women had significantly higher chances of having newborns weighing <2.5 kg than the normotensive women. Conclusion: The preeclamptic women were associated with significantly higher periodontitis and lower fetal birth weight than normotensive women. PMID- 29568174 TI - Oral hygiene and periodontal status in the primitive hidden tribe of Patalkot, a tribal area in Central India. AB - Introduction: Very little is known about the hard to reach tribal communities in India and one such community is a primitive hidden and isolated tribe group of Bharia people in Patalkot. Their health problems need special attention as they have very limited access to health care. The aim of this study is to assess the oral hygiene and periodontal status in the primitive tribe group of Bharias in Patalkot, Madhya Pradesh, India. Materials and Methods: A descriptive cross sectional study was undertaken with sample size of 462 patients. The sample was selected using simple random technique. A predefined pro forma was used to record information about oral hygiene practices and tobacco-related habits. Oral Hygiene Index-simplified (OHI-S), Community Periodontal Index (CPI), and loss of attachment (LOA) were used to assess oral hygiene and periodontal status, respectively. Results: The prevalence of periodontal disease based on CPI scores showed that 35.4 % had periodontal pocket > 6mm. It was also found that 27.9% people had attachment loss of 6-8mm. Mean Debris Index-simplified, Calculus Index simplified, and OHI-S for the participants were 1.59 +/- 0.73, 0.99 +/- 0.70, and 2.56 +/- 1.36, respectively. Poor oral hygiene status was found in 36.3% of Bharias. Conclusion: Higher prevalence of periodontal diseases and poor oral hygiene status in Bharia people can be attributed mainly to their difficult terrain, isolation, very low literacy level, socioeconomic status, and cultural practices. PMID- 29568175 TI - Management of a granulomatous lesion in a patient with Kindler's Syndrome. AB - Kindler's syndrome is a rare vesiculobullous dermatological disorder sometimes involving multiple organs. First described by Kindler. The differential diagnosis includes Rothmund-Thomson syndrome and epidermolysis bullosa. Fisher's criteria have simplified the diagnosis with major and minor criteria. Oral manifestation of this syndrome includes multiple painful oral ulcers in the mucosa, periodontal attachment loss, gingival bleeding, and fragile mucosa. These manifestations may impair proper nutrition intake, may cause growth and development problems. This case report deals with the management of oral and gingival manifestations in a 12 year-old female child patient diagnosed with Kindler's syndrome. PMID- 29568176 TI - Interdisciplinary approach to enhance the esthetics of maxillary anterior region using soft- and hard-tissue ridge augmentation in conjunction with a fixed partial prosthesis. AB - Favorable esthetics is one of the most important treatment outcomes in dentistry, and to achieve this, interdisciplinary approaches are often required. Ridge deficiencies can be corrected for both, soft- and hard-tissue discrepancies. To overcome such defects, not only a variety of prosthetic options are at our disposal but also several periodontal plastic surgical techniques are available as well. Various techniques have been described and revised, over the year to correct ridge defects. For enhancing soft-tissue contours in the anterior region, the subepithelial connective tissue graft is the treatment of choice. A combination of alloplastic bone graft in adjunct to connective tissue graft optimizes ridge augmentation and minimizes defects. The present case report describes the use of vascular interpositional connective tissue graft in combination with alloplastic bone graft for correction of Seibert's Class III ridge deficiency followed by a fixed partial prosthesis to achieve a better esthetic outcome. PMID- 29568177 TI - Multidisciplinary prognostic transition of a molar tooth for long-term survival. AB - Patients with periodontitis may have one or few teeth with hopeless prognosis, which would have to be extracted before initiation of orthodontic therapy. Periodontal therapy aims to prolong the lifespan of dentition, as preserving natural dentition is always the best treatment option. The decision to retain a tooth is always based on the probability of long-term success of one or more treatment modality. A 17-year-old female patient seeking fixed orthodontic treatment presented with the left mandibular first molar tooth (36) having hopeless periodontal prognosis with advanced primary periodontal and secondary endodontic lesion, grade III mobility, and grade II furcation involvement. Root canal treatment followed by periodontal surgery using a combination of bone graft (allograft) and platelet-rich fibrin membrane resulted in a clinical and radiographic indication of periodontal healing. The tooth (36) was even used for orthodontic anchorage 3-month postsurgically and was maintained for 2 years. Appropriate diagnosis and meticulous multidisciplinary treatment approach can lead to the restoration of health and function of the teeth with severe loss of attachment and bone loss and can even be used for orthodontic anchorage. PMID- 29568178 TI - Triangular coronally advanced flap: Conventional versus Microsurgery. AB - Several surgical techniques including pedicle flaps and free soft-tissue grafts have been indicated for the treatment of gingival recession defects with different success rates. Localized gingival recessions can be managed with various root coverage procedures, more specifically, using the coronally advanced flap with distinct designs. Predictable and consistent periodontal plastic surgical results can be achieved by using microsurgical instruments. Periodontal microsurgery involves the use of magnifying devices, microsurgical instruments, and materials in existing basic surgical techniques. It offers definitive advantages in terms of predictability, postoperative morbidity, and patient approval. This case report aims at comparing the modified approach with a triangular type of coronally advanced flap, using conventional and microsurgical approach, for treating bilateral isolated Miller's class I defect in both the maxillary canines by a split-mouth design. PMID- 29568179 TI - Management of multiple recession defects in esthetic zone using platelet-rich fibrin membrane: A 36-month follow-up case report. AB - A patient undergoing orthodontic treatment presented with multiple recession defects in maxillary anterior region. After thorough clinical examination and assessment, measurements were recorded. Maxillary anterior teeth with recession defects of 3-4 mm were treated with coronally advanced flap and platelet-rich fibrin (PRF) membrane. Regular follow-up was maintained for the patient at 3, 6 , 12, 18, 24, 30, and 36 months. After 36 months, significant root coverage of 100 percent was observed in four defects and 50% coverage in one defect. This shows that PRF membrane along with coronally advanced provides a predictable and significant result for management of recession defects. PMID- 29568180 TI - Alleviation of Heat Stress by a Polyherbal Formulation, PhytoceeTM: Impact on Zootechnical Parameters, Cloacal Temperature, and Stress Markers. AB - Background: The range of thermoneutral zone of chickens is narrow, and they become easily susceptible to environmental stress, a common and major concern for poultry causing a production loss. Objective: The present study was designed to comparatively evaluate anti-stress activity of PhytoceeTM and Vitamin C in chickens reared under heat stress. Materials and Methods: A total of 600-day-old chicks of Cobb 400 were randomly assigned to 4 groups with 6 replicates comprising 25 birds each (n = 150). G1 served as a normal control (NC) and supplemented with Vitamin C at 100 g/ton of feed. G2 served as a heat stress control (HSC), subjected to heat stress (34 degrees C-36 degrees C) without Vitamin C supplementation. G3 and G4 served as positive control and treatment group (TC), subjected to heat stress and supplemented with Vitamin C and PhytoceeTM at 100 g/ton of feed, respectively. The impact on zootechnical parameters and cloacal temperature was assessed at regular intervals, and blood was collected at the end of the experiment for evaluation of stress parameters, namely heterophil lymphocyte ratio (H:L ratio) and serum corticosterone. Results: Exposure of chickens to heat stress caused a significant decrease in body weight, worsening of feed conversion ratio, higher mortality, and poor production efficiency. Moreover, serum corticosterone level, H:L ratio, and cloacal temperature were significantly increased in HSC as compared to NC. However, supplementation of PhytoceeTM in feed significantly ameliorated the negative impact of heat stress in broiler birds. Conclusion: The supplementation of PhytoceeTM demonstrated an anti-stress effect in chickens through restoration of serum corticosterone level, H:L ratio, and thermoregulatory mechanism. SUMMARY: Combating heat stress remains a challenge for the broiler industry in the tropics and subtropics, which is even aggravated by the changing climatic conditionsThe present study was designed to evaluate the anti-stressor activity of PhytoceeTM, a polyherbal formulation containing Emblica officinalis, Ocimum sanctum, and Withania somnifera in broiler using heat stress model in comparison with Vitamin CPhytoceeTM demonstrated an anti-stress effect in the current study by ameliorating the negative effects of heat stress on zootechnical parameters, serum corticosterone, heterophil lymphocyte ratio, and cloacal temperature of broilers through modulating the hypothalamic-pituitary-adrenal axis and thermoregulatory mechanismHence, PhytoceeTM could be recommended in broilers and livestock animals for modulating and combating adverse effects of heat stress and thereby reducing the economic losses incurred by farmers.

PMID- 29568182 TI - Quantitative Phytochemical Constituents and Antioxidant Activities of the Mistletoe, Phragmanthera capitata (Sprengel) Balle Extracted with Different Solvents. AB - Objective: The investigation aimed to evaluate the in vitro quantitative phytochemical compositions and antioxidant capacity of the dried leaves of Phragmanthera capitata extracted with different solvents. Methodology: Different phytochemical assays were used to evaluate the phenols, flavonoids, and proanthocyanidin contents of the acetone, methanol, ethanol, and aqueous extracts of the sample. Antioxidant activity was measured using 2,2diphenyl-1 picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), Ferric reducing antioxidant power (FRAP), nitric oxide, and total antioxidant capacity (TAC) assays. Results: Methanol had the highest extraction yield (21.50%) followed by aqueous (10.87%). Acetone and ethanol yielded 6.87% and 4.3%, respectively. However, acetone and ethanol extracts had more phenolic content (218.6 +/- 3.38 and 214.8 +/- 3.56 mg gallic acid equivalent (GAE)/g, respectively) that were significantly higher (P < 0.05) than the methanol and aqueous extracts (203.8 +/- 1.95 and 175.5 +/- 0.32 mg GAE/mg, respectively). Acetone extract also had more flavonoid and proanthocyanidin contents (679.8 +/- 6.26 mg quercetin equivalent/g and 645.7 +/- 6.35 mg catechin equivalent/g, respectively) that were significantly higher than the other solvent extracts (P < 0.05). All the solvent fractions showed great antioxidant activities with the acetone fraction having the highest capacity based on ABTS, DPPH, and TAC assays (half maximal inhibitory concentration [IC50] = <5 MUg/mL, 24.5 MUg/mL, and 85 MUg/mL respectively). The methanol extract however had FRAP and nitric oxide antioxidant activities (IC50 = 302 MUg/mL and < 25 MUg/mL respectively). Conclusion: The findings of this study provide evidence that P. capitata has potential as a natural source of antioxidant with acetone showing to be the best extractant of the polyphenolics with corresponding higher antioxidant activities. SUMMARY: The study investigated the in vitro polyphenolic content and antioxidant activities of the mistletoe; Phragmanthera capitata, extracted with different solventsThe resultant outcome of the study showed that while methanol had more yield from the extraction, the highest polyphenolic contents was observed in the acetone extractThe acetone extract also showed the highest antioxidant activity in most of the assaysThere was a positive correlation between the polyphenolics and the antioxidant activities: Higher polyphenol content resulted in a better antioxidant activityIf extracting this plant for preparatory works only, methanol would be preferred, but if it were for bioassay screening, acetone will be the solvent of choice.

Objectives: To test for the cytotoxicity potentials of 1-6. Materials and Methods: The antiproliferative activities of 1-6 against three human cancer cell lines, breast (MCF-7) and colon (HT-29 and HCT-116), and a normal cell line, human dermal fibroblast neonatal (HDFn), were evaluated using the PrestoBlue(r) cell viability assay. Results: Compounds 4, 1 and 2 (1:2), 2, 1 and 2 (1:1), and 5 exhibited the most cytotoxic effects against HT-29 with half maximal inhibitory concentration (IC50) values of 0.68, 0.74, 0.89, 1.70, and 4.07 MUg/mL, respectively. Comparing 2 with its 1:1 mixture with 1 (IC50 = 1.70 and 7.18 MUg/mL for HT-29 and HCT-116, respectively) and 1:2 mixture with 1 (0.74 and 3.46 MUg/mL for HT-29 and HCT-116, respectively), 2 also showed strong cytotoxic potential against HT-29 and HCT-116 (0.89 and 2.33 MUg/mL, respectively). Unlike the mixtures which exhibited low effects on MCF-7 (IC50 = 20.75 and 30.06 MUg/mL for 1:1 and 1:2, respectively), 2 showed moderate activity against MCF-7 (10.99 MUg/mL). Compound 6 showed the highest cytotoxicity against HCT-116 (IC50 = 4.07 MUg/mL). Conclusion: Mixtures of 1 and 2 (1:1 and 1:2), 2, 3, 4, 5, and 6 from the CH2 Cl2 extracts of the leaves and twigs of W. pubescens (R.Br.) exhibited varying cytotoxic activities. All the compounds except 6 exhibited the strongest cytotoxic effects against HT 29. On the other hand, 6 was most cytotoxic against HCT-116. Overall, the toxicities of 1-6 were highest against HT-29, followed by HCT-116 and MCF-7. All the compounds showed varying activities against HDFn (IC50 < 30 MUg/mL). SUMMARY: Mixtures of ursolic acid (1) and oleanolic acid (2) (1:1 and 1:2), oleanolic acid (2), squalene (3), chlorophyll a (4), wrightiadione (5), and alpha-amyrin acetate (6), isolated from the dichloromethane extracts of the leaves and twigs of Wrightia pubescens (R.Br.), showed varying cytotoxic activities against three human cancer cell lines, breast (MCF-7) and colon (HT-29 and HCT-116), and a normal cell line, human dermal fibroblast-neonatal (HDFn), as evaluated using the PrestoBlue(r) cell viability assay.Abbreviation Used: IC50: Half maximal inhibitory concentration.

AB - Background: Oxidative stress is frequently identified as a key element in the pathophysiology of many complications of diabetes mellitus, including reproductive complications. The antioxidant potential of medicinal plants have been suggested for therapeutic focus of diseases in recent reports. Objective: To investigate the effect of Basella alba (Ba) aqueous leave extract on diabetes induced oxidative stress. Materials and Methods: Forty male Wistar rats (8-10 weeks) were randomly divided into four groups (n = 10) and treated as follows; Control (C + Ns) and Diabetic (D + Ns) animals received oral normal saline 0.5 ml/100 g body weight daily, while Healthy Treatment (H + Ba) and Diabetic Treatment (D + Ba) rats were given Ba extract at an oral dose of 200 mg/kg body weight daily. Treatment was by gavage and lasted 4 weeks in all groups. Diabetes was induced in D + Ns and D + Ba rats by single intraperitoneal injection of streptozotocin (55 mg/kg) and fasting blood sugar (FBS) recorded weekly in all rats afterwards. Animals were euthanized at the end of the experiment and blood samples, pancreas, testes, and epididymis were preserved for analysis of oxidative stress biomarkers. Results: Oral administration of aqueous leave extract of Ba significantly (P < 0.0001) lowered FBS in D + Ba rats. There was significantly higher blood superoxide dismutase activity and serum ferric reducing antioxidant power, but lower serum concentration of conjugated dienes and thiobarbituric acid reactive substances in D + Ba compared to D + Ns rats (P < 0.05). Conclusion: Ba exerts antioxidant effects in the gonads by enhancing antioxidant parameters in circulating blood, but not necessarily in the gonadal tissues.

PMID- 29568185 TI - Thermogenic Blend Alone or in Combination with Whey Protein Supplement Stimulates Fat Metabolism and Improves Body Composition in Mice. AB - Background: Certain food ingredients promote thermogenesis and fat loss. Similarly, whey protein improves body composition. Due to this potential synergistic effect, a blend of thermogenic food ingredients containing African mango, citrus fruit extract, Coleus forskohlii, dihydrocapsiate, and red pepper was tested alone and in combination with a whey protein supplement for its effects on body composition in sedentary mice during high-fat diet. Objective: The objective of this study was to evaluate the interaction of thermogenic foods on improving body composition during consumption of an unhealthy diet. Materials and Methods: C57BL/6J young adult male mice (n = 12) were placed on a 60% high fat diet for 4 weeks and subsequently randomly assigned to receive daily dosing by oral gavage of vehicle, the novel blend alone or with whey protein supplement for another 4 weeks. Body composition, thermal imaging of brown adipose tissue (BAT), mitochondrial BAT uncoupling protein 1 (UCP1), and plasma levels of leptin were assessed. Results: Novel blend alone and in combination with protein supplement attenuated body weight gain, fat, and increased surface BAT temperature in comparison to vehicle control and to baseline (P < 0.5). The combination of novel blend and whey protein supplement also significantly increased UCP1 protein expression in BAT mitochondria in comparison to vehicle control and novel blend alone (P < 0.5). Conclusions: These data indicate that this novel blend stimulates thermogenesis and attenuates the gain in body weight and fat in response to high-fat diet in mice and these effects were improved when administered in combination with whey protein supplement. SUMMARY: 30 days oral administration to mice of a novel blend containing African mango seed extract, citrus fruits extract, Coleus forskohlii root extract, dihydrocapsiate and red pepper fruit extract reduced body weight and fat gain in response to high-fat diet without impairing muscle mass.The novel blend stimulated thermogenesis as shown by the increased thermal imaging and UCP1 protein expression in brown adipose tissue, indicating that improvement in body composition potentially occurred due to a fat-burning effect.The positive effects on body weight, fat, and thermogenesis were improved when the novel blend was administered in combination with a whey protein supplement suggesting that protein provides a synergistic fat-burning effect.

AB - Background: Musa sapientum (banana) plant extract has been shown to possess antioxidant activity in previous studies. Neuronal injury resulting from oxidative stress is an important factor involved in pathogenesis of epilepsy. Objective: The present study aimed to evaluate the anticonvulsant activity of M. sapientum stem extract (MSSE) in acute and chronic experimental models in mice and its effects on various markers of oxidative stress in the brain of pentylenetetrazole (PTZ)-kindled animals. Material and Methods: Maximal electroshock seizures (MES) and PTZ-induced convulsion models were used for acute studies. For the chronic study, the effect of MSSE on the development of kindling was studied. For the evaluation of the effects of MSSE on oxidative stress in brain, malondialdehyde (MDA) and reduced glutathione (GSH) levels were estimated in the brains of the kindled animals. Results: MSSE significantly increased the latency to onset of myoclonic jerks and the duration of clonic convulsions following PTZ administration. The MSSE pretreated group showed significantly reduced mean seizure score on PTZ-induced kindling. There was a significant increase in the brain MDA levels and decrease in GSH levels in response to PTZ induced kindling. On MSSE pretreatment, there was a significant decrease in the MDA levels in the brains, though the increase in the GSH levels was not significant. Conclusion: The results from this study suggest the presence of significant anticonvulsant activity in MSSE, in both acute and chronic PTZ induced seizure models, which could be due to its antioxidant activity, as is reflected by the change in oxidative stress markers in brain.

PMID- 29568190 TI - The Protective Effect of Different Extracts of Three Artemisia Species against H2O2-Induced Oxidative Stress and Apoptosis in PC12 Neuronal Cells. AB - Background: Oxidative stress causes cell damage and is involved in many neurological diseases. The antioxidant properties of plant materials for the maintenance of health and protecting against different diseases stimulated scientist to investigate different herbs. Different Artemisia species have exhibited antioxidant activity. This study aims to investigate whether different Artemisia species could protect the PC12 cells against oxidative stress mediated by H2O2. Methods: For this purpose, different extracts of three Artemisia species (Artemisia aucheri, Artemisia turanica, and Artemisia turcomanica) were prepared using petroleum ether, dichloromethane, ethyl acetate, ethanol, and Water: Ethanol mixture (1:1 volume ratio). The protective effect of the prepared extracts against H2O2-induced cytotoxicity and reactive oxygen species production were compared. The effect of treatment of PC12 cells with different extracts on total glutathione (GSH) level, caspase-3 activity, and mitochondrial membrane potential were also compared. Results: The A. aucheri extracts could not rescue the PC12 cells from oxidative stress consequences. The A. turanica and A. turcomanica extracts were found potent in suppressing the toxicity and apoptosis of PC12 cells mediated by H2O2 and significantly antagonized the H2O2-induced GSH depletion. The hydroethanolic and ethyl acetate extracts of A. turanica and the petroleum ether and hydroethanolic extracts of A. turcomanica more efficiently suppressed cytotoxicity and loss of GSH caused by H2O2. Conclusion: This study shows the protective effects of Artemisia extracts on PC12 cell line and suggested that these species could be also considered as promising neuroprotective agents in treatment of different neurodegenerative diseases. SUMMARY: Artemisia turanica and Artemisia turcomanica extracts were found to potentially exert neuroprotective effect on PC12 cells. The results exhibited that the cytoprotective potential and anti-apoptotic mechanism of these species is not the same for different extracts, and suggested that based on the type of species and the type of solvents used in extraction, both intrinsic and extrinsic pathways could be included in the anti-apoptotic mechanism of these species.

PMID- 29568195 TI - Evaluation of Antithrombotic Activities of Solanum xanthocarpum and Tinospora cordifolia. AB - Background: Solanum xanthocarpum and Tinospora cordifolia have been reported to exhibit anti-inflammatory, antiarthritic, antioxidant, antiallergic, and hepatoprotective activities. The origins of many of the currently available antithrombotic treatments are from natural products and natural sources. Objective: To investigate the antithrombotic activities of methanolic leaf extracts of S. xanthocarpum(SXME) and T. cordifolia(TCME). Materials and Methods: Antithrombotic activities were assessed by thrombin inhibition assay, thrombin generation assay, platelet adhesion assay on collagen-coated surface, and platelet PAC1-FITC binding by flow cytometry. Results: SXME significantly inhibited thrombin activity at 5-20 mg/ml concentrations, whereas TCME inhibited thrombin activity at 500 MUg/ml-5 mg/ml concentrations. Further, SXME inhibited thrombin generation at 2-20 mg/ml concentrations, whereas TCME exhibited significant inhibition at 200 MUg/ml, suggesting that TCME has higher efficacy as compared to SXME. Moreover, SXME did not inhibit platelet adhesion on collagen coated surface, whereas TCME inhibited platelet adhesion on collagen-coated surface at 5 mg/ml. Indomethacin showed significant inhibition in platelet adhesion at 300 MUM. Further, SXME inhibited thrombin-induced platelet activation (PAC1-FITC binding) significantly at 1 mg/ml by about 80%, whereas TCME inhibited thrombin-induced platelet activation (PAC1-FITC binding) by about 40% at 1 mg/ml. Conclusion: These results strongly suggested that SXME and TCME possess antithrombotic activities. However, further studies are essential to find out the active constituent responsible for antithrombotic effect. SUMMARY: The methanolic extracts obtained from the leaves of Tinospora cordifolia and Solanum xanthocarpum were evaluated for antithrombotic activity by thrombin inhibition assay, thrombin generation assay, platelet adhesion assay and platelet activation assay by flow cytometry.

PMID- 29568196 TI - Anti-inflammatory Effect of an Extract of Agave americana on Experimental Animals. AB - Background: Medicinal plants have the potential treasure to treat medical conditions for a long time based on error and trial method. Agave americana has been known as century plant or American aloe. The leaves contain genins, saponins, steroidal flavonoids, isoflavones, and coumarins. It has long been used for anti-inflammatory effects. Objectives: This study was designed to evaluate the anti-inflammatory activity of the extract of A. americana. Materials and Methods: A. americana leaves extract is collected and the extract is done by percolation method. Inflammation is induced in experimental animals' carrageenan induced paw edema model and cotton pellet-induced granuloma model. The extract of A. americana and standard, aspirin and indomethacin are given orally for the anti inflammatory effects. The anti-inflammatory effects were measured at regular intervals of time to see the percentage inhibition of paw edema and reduction of weight of granuloma with percentage protection to compare the effect of the extract with the control and standard. Results: The extract of A. americana showed improved in percentage inhibition of paw edema in graded doses of hydroalcoholic extract of A. americana (HEAA) as compared with control in carrageenan-induced paw edema model. The percentage inhibition of 400 mg/kg of HEAA at the 3rd h is almost comparable with the standard, aspirin. On the other hand, graded doses (200 and 400 mg/kg) showed a highly significant reduction (P < 0.001) in the weights of granuloma in comparison with the control in cotton pellet-induced granuloma model. The percentage inhibition of weight of granuloma by 400 mg/kg of HEAA is quite comparable to the standard, Indomethacin. Conclusion: Anti-inflammatory activity is seen with the graded dose of HEAA. The plant contains flavonoids and genins which have been shown to have anti-edematous effects in the acute phase of inflammation. Thus, the plant contributes to its anti-inflammatory activity. Thus, higher doses of A. americana leaves need to be used to have the better understanding of the mechanism of anti-inflammation. SUMMARY: The hydroalcoholic extract from Agave americana (100, 200, and 400 mg/kg, HEAA) were studied in carrageenan-induced paw edema model and cotton pellet-induced granuloma model in Wistar rats. The plant contains flavonoids and genins which have been shown to have anti-edematous effects in the acute phase of inflammation. The results were good with the higher doses of 200 and 400 mg/kg of HEAA. Its in vivo anti-inflammatory activity is in good agreement with the traditional use of A. americana.

Results: Datura (ayurvedic preparation) was found to be nontoxic up to 2000 mg/kg in Swiss albino mice, i.e., 60 mg/30 g of mice, when administered (0.5 ml) orally and observed till 21 days. Up to 20% survival rate on the test group (PE of Datura extracts) up to 14 days postinfection as compared to the virus control group (10 LD50) was observed. No survival rate was observed in the postexposure group of Datura extract; however, the survival time was increased by 4 days as compared to the virus control group. Viral load of the infected mice brain sample was estimated in vero cell line, and 3 log reduction in the virus titer was observed in text group as compared to the virus control, suggesting that Datura extract has an in vivo antirabies activity. Conclusion: To the best of our knowledge, this is the first study of in vivo antiviral activity of an ayurvedic preparation of D. metel Linn. against rabies virus. Datura extracts have a potential in vivo antirabies activity. SUMMARY: In the present study, Datura metel Linn. (ayurvedic preparation) extract exhibited survival (20%) in the preexposure (PE) of the virus and the survival time was increased in the postexposure treatment where the disease was established. The mortality was observed, and the viral load was determined by titration method. Abbreviation Used: TCID50: tissue culture infectious dose 50; LD50: lethal dose 50; RV CVS: Rabies virus challenge virus standard; PE: Pre exposure; IC: intracerebral; PI: post infection; FITC: Fluorescein isothiocyanate. PMID- 29568198 TI - Comparative Molluscicidal and Schistosomicidal Potentiality of Two Solanum Species and Its Isolated Glycoalkaloids. AB - : Schistosomiasis is the most noteworthy parasitic disease after malaria. Furthermore, the significant activity of the genus Solanum against Schistosoma worms and its intermediate host snails reinforced the study of Solanum seaforthianum Andr. (SS) and Solanum macrocarpon L. (SM) for their molluscicidal and schistosomicidal potentiality. In this study, different extracts, fractions and isolated compounds of both Solanum species are evaluated for the molluscicidal and schistosomicidal potentialities. The niclosamide was used as positive molluscicide control against Biomphalaria alexandrina snails. Different extracts, fractions, or isolated compounds were used at a concentration of 100 MUg/ml and dead snails were counted in each case. On the other hand, washed and sterilized Schistosoma mansoni adult worms were used in three replicates, and three worm pairs were placed in each well with 2 ml test solution of 100 MUg/ml concentration. Positive (praziquantel [PZQ] 0.2 ug/ml) and negative controls were concurrently used and examined daily for 3 days for viability. The mortality rate was calculated and then both LC50 and LC90 were determined in triplicates. Highest potency was indicated to total glycoalkaloid (TGA) fraction of SM followed by TGA of SS. On the other hand, TGA fractions of both species showed higher potency than other extracts and isolated compounds. Meanwhile, solasodine free aglycone showed declined activity compared to its glycosides. Promising molluscicidal and schistosomicidal activities were displayed which are attributed to the glycoalkaloid content. Therefore, this study can efficiently contribute toward validation of the traditional use of SS and SM in schistosomiasis control. SUMMARY: The current study evaluated the molluscicidal and schistosomicidal activities of different extracts and fractions of two Solanum species. The glycoalkaloids content depicted a promising activity against both the snails and the adult worms. Abbreviations Used: PZQ; Praziquantel, SM; Solanum macrocarpon, SS; Solanum seaforthianum, TGA; total glycoalkaloid.

AB - AIM: To investigate disease-specific gene expression profiles of peripheral blood mononuclear cells (PBMCs) from Crohn's disease (CD) patients in clinical remission. METHODS: Patients with CD in clinical remission or with very low disease activity according to the Crohn's disease activity index were genotyped regarding nucleotide-binding oligomerization domain 2 (NOD2), and PBMCs from wild type (WT)-NOD2 patients, patients with homozygous or heterozygous NOD2 mutations and healthy donors were isolated for further analysis. The cells were cultured with vitamin D, peptidoglycan (PGN) and lipopolysaccharide (LPS) for defined periods of time before RNA was isolated and subjected to microarray analysis using Clariom S assays and quantitative real-time PCR. NOD2- and disease-specific gene expression profiles were evaluated with repeated measure ANOVA by a general linear model. RESULTS: Employing microarray assays, a total of 267 genes were identified that were significantly up- or downregulated in PBMCs of WT-NOD2 patients, compared to healthy donors after challenge with vitamin D and/or a combination of LPS and PGN (P < 0.05; threshold: >= 2-fold change). For further analysis by real-time PCR, genes with known impact on inflammation and immunity were selected that fulfilled predefined expression criteria. In a larger cohort of patients and controls, a disease-associated expression pattern, with higher transcript levels in vitamin D-treated PBMCs from patients, was observed for three of these genes, CLEC5A (P < 0.030), lysozyme (LYZ; P < 0.047) and TREM1 (P < 0.023). Six genes were found to be expressed in a NOD2-dependent manner (CD101, P < 0.002; CLEC5A, P < 0.020; CXCL5, P < 0.009; IL-24, P < 0.044; ITGB2, P < 0.041; LYZ, P < 0.042). Interestingly, the highest transcript levels were observed in patients with heterozygous NOD2 mutations. CONCLUSION: Our data identify CLEC5A and LYZ as CD- and NOD2-associated genes of PBMCs and encourage further studies on their pathomechanistic roles. PMID- 29568199 TI - Functional macrophages and gastrointestinal disorders. AB - Macrophages (MPhi) differentiate from blood monocytes and participate in innate and adaptive immunity. Because of their abilities to recognize pathogens and activate bactericidal activities, MPhi are always discovered at the site of immune defense. MPhi in the intestine are unique, such that in the healthy intestine, they possess complex mechanisms to protect the gut from inflammation. In these complex mechanisms, they produce anti-inflammatory cytokines, such as interleukin-10 and transforming growth factor-beta, and inhibit the inflammatory pathways mediated by Toll-like receptors. It has been demonstrated that resident MPhi play a crucial role in maintaining intestinal homeostasis, and they can be recognized by their unique markers. Nonetheless, in the inflamed intestine, the function of MPhi will change because of environmental variation, which may be one of the mechanisms of inflammatory bowel disease (IBD). We provide further explanation about these mechanisms in our review. In addition, we review recent discoveries that MPhi may be involved in the development of gastrointestinal tumors. We will highlight the possible therapeutic targets for the management of IBD and gastrointestinal tumors, and we also discuss why more details are needed to fully understand all other effects of intestinal MPhi. PMID- 29568201 TI - Three-microRNA signature identified by bioinformatics analysis predicts prognosis of gastric cancer patients. AB - AIM: To identify multiple microRNAs (miRNAs) for predicting the prognosis of gastric cancer (GC) patients by bioinformatics analysis. METHODS: The original microarray dataset GSE93415, which included 20 GC and 20 tumor adjacent normal gastric mucosal tissues, was downloaded from the Gene Expression Omnibus database and used for screening differentially expressed miRNAs (DEMs). The cut-off criteria were P < 0.05 and fold change > 2.0. In addition, we acquired the miRNA expression profiles and clinical information of 361 GC patients from The Cancer Genome Atlas database to assess the prognostic role of the DEMs. The target genes of miRNAs were predicted using TargetScan, miRDB, miRWalk, and DIANA, and then the common target genes were selected for functional enrichment analysis. RESULTS: A total of 110 DEMs including 19 up-regulated and 91 down-regulated miRNAs were identified between 20 pairs of GC and tumor adjacent normal tissues, and the Kaplan-Meier survival analysis found that a three-miRNA signature (miR 145-3p, miR-125b-5p, and miR-99a-5p) had an obvious correlation with the survival of GC patients. Furthermore, univariate and multivariate Cox regression analyses indicated that the three-miRNA signature could be a significant prognostic marker in GC patients. The common target genes of the three miRNAs are added up to 108 and used for Gene Functional Enrichment analysis. Biological Process and Molecular Function analyses showed that the target genes are involved in cell recognition, gene silencing and nucleic acid binding, transcription factor activity, and transmembrane receptor activity. Cellular Component analysis revealed that the genes are portion of nucleus, chromatin silencing complex, and TORC1/2 complex. Biological Pathway analysis indicated that the genes participate in several cancer-related pathways, such as the focal adhesion, PI3K, and mTOR signaling pathways. CONCLUSION: This study justified that a three-miRNA signature could play a role in predicting the survival of GC patients. PMID- 29568202 TI - Differing profiles of people diagnosed with acute and chronic hepatitis B virus infection in British Columbia, Canada. AB - AIM: To describe the characteristics of people diagnosed with acute and chronic hepatitis B virus (HBV) infection in British Columbia (BC). METHODS: We used data from the BC Hepatitis Testers Cohort (BC-HTC), which includes all individuals tested for hepatitis C virus (HCV) or human immunodeficiency virus (HIV) or those diagnosed with HBV or active tuberculosis in BC since 1990. These data were integrated with prescription drug, medical visit, hospitalization and mortality data. HBV cases were classified as acute or chronic according to provincial guidelines. We compared characteristics of individuals by HBV infection group (acute, chronic and negative). Factors associated with acute or chronic HBV infection were assessed with multinomial logistic regression models in comparison to the HBV negative group. RESULTS: 46498 of the 1058056 eligible BC-HTC participants were diagnosed with HBV infection. 4.3% of HBV positive individuals were diagnosed with acute HBV infections while 95.7% had chronic infections. Problematic alcohol use, injection drug use, and HIV or HCV co-infection were more common among individuals diagnosed with acute HBV compared to those with chronic infections and HBV negative individuals. In multivariable multinomial logistic regression models, we observed significant associations between acute or chronic HBV diagnosis and being male, age at HBV diagnosis or birth cohort, South and East Asian ethnicity, HCV or HIV infection, and injection drug use. The odds of acute HBV decreased with increasing age among people who inject drugs, while the opposite was true for chronic HBV. Persons with acute HBV were predominantly White (78%) while those with chronic HBV were mostly East Asian (60%). Relative to Whites, East Asians had 12 times greater odds of being diagnosed with chronic HBV infection. These odds increased with increasing socioeconomic deprivation. CONCLUSION: Differences in the profiles of people diagnosed with acute and chronic HBV infection necessitate differentiated screening, prevention, care and treatment programs. PMID- 29568203 TI - Role of relevant immune-modulators and cytokines in hepatocellular carcinoma and premalignant hepatic lesions. AB - AIM: To assess the levels of different immune modulators in patients with hepatocellular carcinoma (HCC), in relation to other hepatic diseases. METHODS: Eighty-eight patients were included in the current study and represented patients with HCC (20), liver cirrhosis (28) and chronic hepatitis (CH; 25), and normal controls (NC; 15). Peripheral blood was isolated for immunophenotyping of active myeloid dendritic cells (mDCs; CD1c and CD40), mature inactive myeloid cells (CD1c and HLA), active plasmacytoid cells (pDCs; CD303 and CD40), mature inactive pDCs (CD30 and HLA), active natural killer (NK) cells (CD56 and CD161), active NK cells (CD56 and CD314) and inactive NK cells (CD56 and CD158) was done by flow cytometry. Serum levels of interleukin (IL)-2, IL-10, IL-12, IL-1beta, interferon (IFN)-alpha, IFN-gamma and tumor necrosis factor (TNF)-alphaR2 were assessed by ELISA. RESULTS: Active mDCs (CD1C+/CD40+) and inactive mDCs (CD1c+/HLA+) were significantly decreased in HCC patients in relation to NC (P < 0.001). CD40+ expression on active pDCs was decreased in HCC patients (P < 0.001), and its level was not significantly changed among other groups. Inactive pDCs (CD303+/HLA+), inactive NKs (CD56+/CD158+) and active NKs (CD56+/CD161+) were not statistically changed among the four groups studied; however, the latter was increased in CH (P < 0.05). NKG2D was statistically decreased in HCC, CH and cirrhosis (P < 0.001), and it was not expressed in 63% (12/20) of HCC patients. There was significant decrease of IL-2, IFN-alpha and IFN-gamma (P < 0.001), and a significant increase in IL-10, IL-1beta, and TNF-alphaR2 (P <0.01, P < 0.001 and P < 0.001; respectively) in HCC patients. There was inverted correlation between IL-12 and IL-1beta in HCC (r = -0.565, P < 0.01), with a strong correlation between pDCs (CD303+/CD40+) and NKs (CD56+/CD161+; r = 0.512, P < 0.05) as well as inactive mDCs (CD1c+/HLA+) and inactive NK cells (CD56+/CD158+; r = 0.945, P < 0.001). CONCLUSION: NKG2D, CD40, IL-2 and IL-10 are important modulators in the development and progression of HCC. PMID- 29568204 TI - Serum autotaxin levels are correlated with hepatic fibrosis and ballooning in patients with non-alcoholic fatty liver disease. AB - AIM: To examine the relationship between serum autotaxin (ATX) concentrations and clinicopathological findings in non-alcoholic fatty liver disease (NAFLD) patients. METHODS: One hundred eighty-six NAFLD patients who had undergone liver biopsy between 2008 and 2017 were retrospectively enrolled. Serum samples were collected at the time of biopsy and ATX was measured by enzyme immunoassays. Sera obtained from 160 healthy, non-obese individuals were used as controls. Histological findings were graded according to an NAFLD scoring system and correlations with serum ATX were calculated by Spearman's test. Diagnostic accuracy was evaluated using the area under the receiver operating characteristic curve (AUC). Cut-off values were identified by the Youden index, and the nearest clinically applicable value to the cutoff was considered the optimal threshold for clinical convenience. RESULTS: Serum ATX levels were significantly higher in NAFLD patients than in controls (0.86 mg/L vs 0.76 mg/L, P < 0.001) and correlated significantly with ballooning score and fibrosis stage (r = 0.36, P < 0.001 and r = 0.45, P < 0.001, respectively). Such tendencies were stronger in female patients. There were no remarkable relationships between ATX and serum alanine aminotransferase, lipid profiles, or steatosis scores. The AUC values of ATX for predicting the presence of fibrosis (>= F1), significant fibrosis (>= F2), severe fibrosis (>= F3), and cirrhosis (F4), were all more than 0.70 in respective analyses. CONCLUSION: Serum ATX levels may at least partially reflect histological severity in NAFLD. PMID- 29568205 TI - Epidemiological features of chronic hepatitis C infection caused by remunerated blood donors: A nearly 27-year period survey. AB - AIM: To understand the prevalence of hepatitis C virus (HCV) infection in blood donors over a nearly 27-year interval and to explore the factors that affect the outcome of HCV infection. METHODS: A retrospective and cross-sectional study was conducted. The participants, mostly plasma donors, were selected from three administrative villages in the Jiangsu province in Eastern China. A questionnaire was administered among the villagers who had a history of blood donation from the late 1980s to the early 1990s. All participants underwent physical examination, liver B-ultrasonography, and liver stiffness measurement. In addition, 10 mL of blood was collected from each participant to measure simple liver function parameters (albumin, alanine aminotransferase, aspirate aminotransferase), blood factors (platelet), and for hepatitis B surface antigen, antiHCV, and antihuman immunodeficiency virus detection. HCV RNA detection, HCV genotyping, and other tests were carried out in antiHCV-positive patients. RESULTS: After a median of 27 years (25-31 years) from the last blood donation to the time of survey, a total of 1694 participants were investigated, and the antiHCV-positive individuals were categorized into three groups: blood donors (n = 12, 3.3%), plasma donors (n = 534, 68.5%), and mixed donors (n = 324, 58.8%). A total of 592 (68.05%) patients had detectable HCV RNA, and 91.9% had genotype 1b. A total of 161 (27.2%, 161/592) patients with chronic HCV were considered to have cirrhosis with a liver stiffness measurement level higher than 12 kPa. Multiple logistic (binary) regression analysis results showed that platelet and IgG levels were associated with cirrhosis. CONCLUSION: The nearly 27-year interval investigation revealed that chronic hepatitis C infection is a very serious public health problem in Eastern China. Plasma donation and subsequent return of blood cells to the donor are the main causes of hepatitis C infection. The main HCV genotype is 1b. Nearly 28% of cases progressed to cirrhosis. Age, especially over 60 years, and regular drinking habits were risk factors associated with cirrhosis. PMID- 29568206 TI - Low-FODMAP vs regular rye bread in irritable bowel syndrome: Randomized SmartPill(r) study. AB - AIM: To compare the effects of regular vs low-FODMAP rye bread on irritable bowel syndrome (IBS) symptoms and to study gastrointestinal conditions with SmartPill(r). METHODS: Our aim was to evaluate if rye bread low in FODMAPs would cause reduced hydrogen excretion, lower intraluminal pressure, higher colonic pH, different transit times, and fewer IBS symptoms than regular rye bread. The study was a randomized, double-blind, controlled cross-over meal study. Female IBS patients (n = 7) ate study breads at three consecutive meals during one day. The diet was similar for both study periods except for the FODMAP content of the bread consumed during the study day. Intraluminal pH, transit time, and pressure were measured by SmartPill, an indigestible motility capsule. RESULTS: Hydrogen excretion (a marker of colonic fermentation) expressed as area under the curve (AUC)(0-630 min) was [median (range)] 6300 (1785-10800) ppm?min for low-FODMAP rye bread and 10 635 (4215-13080) ppm?min for regular bread (P = 0.028). Mean scores of gastrointestinal symptoms showed no statistically significant differences but suggested less flatulence after low-FODMAP bread consumption (P = 0.063). Intraluminal pressure correlated significantly with total symptom score after regular rye bread (rho = 0.786, P = 0.036) and nearly significantly after low-FODMAP bread consumption (rho = 0.75, P = 0.052). We found no differences in pH, pressure, or transit times between the breads. Gastric residence of SmartPill was slower than expected. SmartPill left the stomach in less than 5 h only during one measurement (out of 14 measurements in total) and therefore did not follow on par with the rye bread bolus. CONCLUSION: Low-FODMAP rye bread reduced colonic fermentation vs regular rye bread. No difference was found in median values of intraluminal conditions of the gastrointestinal tract.

PMID- 29568208 TI - Low-pressure pneumoperitoneum with abdominal wall lift in laparoscopic total mesorectal excision for rectal cancer: Initial experience. AB - AIM: To evaluate the safety and feasibility of a new technology combining low pressure pneumoperitoneum (LPP) and abdominal wall lift (AWL) in laparoscopic total mesorectal excision (TME) for rectal cancer. METHODS: From November 2015 to July 2017, 26 patients underwent laparoscopic TME for rectal cancer using LPP (6 8 mmHg) with subcutaneous AWL in Qilu Hospital of Shandong University, Jinan, China. Clinical data regarding patients' demographics, intraoperative monitoring indices, operation-related indices and pathological outcomes were prospectively collected. RESULTS: Laparoscopic TME was performed in 26 cases (14 anterior resection and 12 abdominoperineal resection) successfully, without conversion to open or laparoscopic surgery with standard-pressure pneumoperitoneum. Intraoperative monitoring showed stable heart rate, blood pressure and paw airway pressure. The mean operative time was 194.29 +/- 41.27 min (range: 125-270 min) and 200.41 +/- 20.56 min (range: 170-230 min) for anterior resection and abdominoperineal resection, respectively. The mean number of lymph nodes harvested was 16.71 +/- 5.06 (range: 7-27). There was no positive circumferential or distal resection margin. No local recurrence was observed during a median follow-up period of 11.96 +/- 5.55 mo (range: 5-23 mo). CONCLUSION: LPP combined with AWL is safe and feasible for laparoscopic TME. The technique can provide satisfactory exposure of the operative field and stable operative monitoring indices. PMID- 29568207 TI - Fatty liver in hepatitis C patients post-sustained virological response with direct-acting antivirals. AB - AIM: To determine steatosis and fibrosis prevalence in hepatitis C patients after a sustained virological response achieved with direct-acting antivirals. METHODS: Transient elastography with controlled attenuation parameter (CAP) was used to assess hepatic steatosis post-sustained virological response (SVR); the CAP technology was not available in the United States at study initiation. Liver stiffness/fibrosis was measured before and 47 wk after treatment completion. Patients with genotype 3 and patients with cirrhosis were excluded. RESULTS: One hundred and one patients were included in the study. Post-SVR there were decreases from baseline in alanine aminotransferase (ALT) (63.1 to 17.8 U/L), aspartate aminotransferase (51.8 to 21.5 U/L) and fibrosis score (7.4 to 6.1 kPa) (P < 0.05). Post-SVR, 48 patients (47.5%) had steatosis on CAP; of these, 6.25% had advanced fibrosis. Patients with steatosis had higher body mass index (29.0 vs 26.1 kg/m2), glucose (107.8 vs 96.6 mg/dL), ALT (20.4 vs 15.3 mg/dL), CAP score (296.3 vs 212.4 dB/m) and fibrosis score (7.0 vs 5.3 kPa); P < 0.05. Interestingly, compared to baseline, both patients with and without steatosis had change in fibrosis score post-SVR (7.7 kPa vs 7.0 kPa and 7.0 kPa vs 5.3 kPa); alternatively, (P < 0.05) and therefore patients with steatosis continued to have clinically significant stiffness (>= 7 kPa). CONCLUSION: Fatty liver is very common in hepatitis C virus (HCV) patients post-SVR. These patients continue to have elevated mean fibrosis score (>= 7 kPa) compared to those without fatty liver; some have advanced fibrosis. Long term follow up is needed to assess steatosis and fibrosis in HCV patients post-SVR.

PMID- 29568212 TI - Effectiveness of Cognitive Behavioral Therapy for Individuals with Autism Spectrum Disorders and Comorbid Obsessive-Compulsive Disorder: A Review of the Research. AB - Autism spectrum disorders (ASD) and obsessive-compulsive disorder (OCD) are highly comorbid, precipitating an urgent need to identify evidence-based practices that might be used to address this comorbidity exclusively. The aim of this study was to conduct a review of intervention research and clinical reports to examine the use of cognitive behavioral therapy (CBT) with individuals who have comorbid ASD and OCD. Based on the pre-determined review inclusion criteria, 11 studies were included in the review: three randomized control trials (RCT), one case controlled study, two single subject experimental designs, and five case studies. These studies offer promising data on the use of CBT interventions for individuals with ASD and comorbid OCD as well as for individuals with OCD and comorbid ASD when standard CBT protocol is enhanced with modifications such as parental involvement, increased use of visuals, personalized treatment metaphors, self-monitoring, positive reinforcement, and use of clear language and instructions. Limitations and implications for future research and practice are discussed. PMID- 29568213 TI - The Role of Organizational Control Systems in Employees' Organizational Trust and Performance Outcomes. AB - This study examined how organizational control is related to employees' organizational trust. We specifically focus on how different forms of control (process, outcome, and normative) relate to employees' trust in their employing organizations and examine whether such trust in turn relates positively to employee job performance (task performance and organizational citizenship behavior). In addition, and in response to the recommendations of past research, we examined these relationships in a high control and compliance-based cultural context. Using data from 105 employee-supervisor dyads from professional services firms in Singapore, we find support for our hypothesized model. The implications of the results for theory and practice, and directions for future research, are discussed. PMID- 29568214 TI - The Role of Occupational Identification During Post-Merger Integration. AB - Integration processes after mergers are fraught with difficulties, and constitute a main cause of merger failure. This study focuses on the human aspect of post merger integration, and in particular, on the role of occupational identification. We theorize and empirically demonstrate by means of a survey design that employees' identification with their occupation is positively related to their willingness to cooperate in the post-merger integration process, over and above the effect of organization members' organizational identification. This positive effect of occupational identification is stronger for uniformed personnel but attenuates in the course of the integration process. Qualitative interviews further explore and interpret the results from our statistical analysis. Together, these findings have important practical implications and suggest future research directions. PMID- 29568215 TI - Coworkers' Perspectives on Mentoring Relationships. AB - Research into workplace mentoring is primarily focused on the experiences and perceptions of individuals involved in the relationship, while there is scarcely any research focusing on the impact of mentoring relationships on their social environment. This exploratory research aims to give insight into how coworkers' perceptions and experiences of informal mentoring relationships in their workgroup are related to their perceptions of workgroup functioning. The results of 21 semistructured interviews show that coworkers believe that mentoring relationships affect their workgroup's functioning by influencing both their workgroup's performance and climate. Coworkers applied an instrumental perspective and described how they think that mentoring relationships both improve and hinder their workgroup's performance as they influence the individual functioning of mentor and protege, the workgroup's efficiency, and organizational outcomes. Furthermore, coworkers applied a relational perspective and described how mentoring relationships may influence their workgroup's climate in primarily negative ways as they may be perceived as a subgroup, cause feelings of distrust and envy, and are associated with power issues. The results of this study emphasize the importance of studying mentoring relationships in their broader organizational context and set the groundwork for future research on mentoring relationships in workgroups. PMID- 29568216 TI - Foster children's behavioral development and foster parent stress: testing a transactional model. AB - The goal of this three-wave longitudinal study was to analyze foster parent stress and foster children's internalizing and externalizing behaviors in a transactional framework. Participants in this study were 237 children in foster care in the Netherlands with, mostly, long placement durations (M = 56.86 months, SD = 49.10 months). We examined concurrent, prospective unidirectional and bidirectional relations between foster children's behavior and foster parent stress by using cross-lagged structural equation modeling and examined whether the results were stable across different subgroups of foster children. In contrast to our hypothesis, we found no bidirectional relations. There were unidirectional prospective pathways from foster children's internalizing and externalizing problems to foster parent stress, but no significant prospective pathways from foster parent stress to foster children's internalizing and externalizing problems. The results were fairly stable across different subgroups of foster children. The lack of bidirectional relations was unexpected given the presence of transactional relations in biological parent-child dyads. Foster parents seem not to influence their foster children when it comes to regulating problem behavior. Therefore, the question is whether foster parents can, in more general terms, help their foster children benefit from their improved home environment. PMID- 29568218 TI - Efficient Acceleration of the Pair-HMMs Forward Algorithm for GATK HaplotypeCaller on Graphics Processing Units. AB - GATK HaplotypeCaller (HC) is a popular variant caller, which is widely used to identify variants in complex genomes. However, due to its high variants detection accuracy, it suffers from long execution time. In GATK HC, the pair-HMMs forward algorithm accounts for a large percentage of the total execution time. This article proposes to accelerate the pair-HMMs forward algorithm on graphics processing units (GPUs) to improve the performance of GATK HC. This article presents several GPU-based implementations of the pair-HMMs forward algorithm. It also analyzes the performance bottlenecks of the implementations on an NVIDIA Tesla K40 card with various data sets. Based on these results and the characteristics of GATK HC, we are able to identify the GPU-based implementations with the highest performance for the various analyzed data sets. Experimental results show that the GPU-based implementations of the pair-HMMs forward algorithm achieve a speedup of up to 5.47* over existing GPU-based implementations. PMID- 29568217 TI - Mutational screening of germline RB1 gene in Vietnamese patients with retinoblastoma reveals three novel mutations. AB - Purpose: Retinoblastoma (Rb) is a rare and unique eye cancer that usually develops in the retinas of children less than 5 years old due to mutations in the RB1 gene. About 40% of affected individuals have the heritable form making genetics testing of the RB1 gene important for disease management. This study aims to identify germline mutations in RB1 in a cohort of patients with Rb from northern Vietnam. Methods: Genomic DNA was extracted from peripheral blood of 34 patients with Rb (nine unilateral and 25 bilateral cases) and their available parents. Twenty-seven exons, flanking sequences, and the promoter region of RB1 gene were screened for mutations with direct PCR sequencing. Multiplex ligation dependent probe amplification (MLPA) was applied for patients with negative sequencing results. In the mutation-positive patients, their available parental DNA was analyzed to determine the parental origin of the mutation. Results: Germline mutations in RB1 were identified in 25 (73.53%) of 34 patients (four unilateral and 21 bilateral cases). Of these mutations, 19 were detected, including seven nonsense, six frameshift, four splice-site (one was identified in two siblings), and one missense, with Sanger sequencing. Three novel frameshift mutations were discovered in one unilateral and two bilateral patients. MLPA detected mutations in the RB1 gene in six bilateral cases, of whom five had a whole gene deletion (three familial cases) and one had a partial gene deletion (from exon 4 to exon 27) in one allele of the RB1 gene. Parental testing showed five mutations originated from the fathers and one was inherited from a mother who was mosaic for the mutation. Conclusions: This study provides a data set of germline mutations in the RB1 gene in Vietnamese patients with retinoblastoma. Screening of mutations in the RB1 gene can help to identify heritable Rb and contribute to clinical management and genetic counseling for affected families. PMID- 29568219 TI - Technical Validation of a Reverse-Transcription Quantitative Polymerase Chain Reaction In Vitro Diagnostic Test for the Determination of MiR-31-3p Expression Levels in Formalin-Fixed Paraffin-Embedded Metastatic Colorectal Cancer Tumor Specimens. AB - MiR-31-3p expression has been shown to be a predictive biomarker for response to anti-epithelial growth factor receptor therapy in patients with RAS wild-type metastatic colorectal cancer (mCRC). To aid in the quantification of miR-31-3p expression in formalin-fixed paraffin-embedded (FFPE) primary tumor samples from patients with mCRC, a reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay was developed and validated. Assay development included the identification of a microRNA reference standard and the determination of an appropriate relative quantification cutoff for differentiating low versus high miR-31-3p expression. Sample specimens for the validation studies included both FFPE slides and shavings. Polymerase chain reaction (PCR) efficiency and linearity, analytical sensitivity and specificity, assay robustness, reproducibility, and accuracy were demonstrated across a number of test conditions and differing quantitative PCR platforms. The data from this study provide evidence as to the feasibility of quantifying the expression of miR-31-3p from FFPE tumor tissue using a standardized RT-qPCR assay.

AB - Leishmania infantum chagasi is an intracellular protozoan parasite responsible for visceral leishmaniasis, a fatal disease in humans. Heparin-binding proteins (HBPs) are proteins that bind to carbohydrates present in glycoproteins or glycolipids. Evidence suggests that HBPs present on Leishmania surface participate in the adhesion and invasion of parasites to tissues of both invertebrate and vertebrate hosts. In this study, we identified the product with an HSP90 (heat shock protein 90) domain encoded by lipophosphoglycan (LPG3) gene as a L infantum chagasi HBP (HBPLc). Structural analysis using the LPG3 recombinant protein suggests that it is organized as a tetramer. Binding analysis confirms that it is capable of binding heparin with micromolar affinity. Inhibition of adenosine triphosphatase activity in the presence of heparin, molecular modeling, and in silico docking analysis suggests that heparin-binding site superimposes with the adenosine triphosphate-binding site. Together, these results show new properties of LPG3 and suggest an important role in leishmaniasis. PMID- 29568221 TI - Can We Predict Which Adolescents Will Engage in Outpatient Substance Abuse Treatment? AB - Understanding which adolescents remain in substance abuse treatment may facilitate the development of effective strategies for enhancing engagement and retention. Using clinical service data from a large naturalistic sample of adolescents, we examined whether client characteristics predict retention in outpatient alcohol and other drug (AOD) treatment. chi2 tests and multinomial logistic regressions were conducted to examine relationships between sociodemographic and substance use variables and clinic attendance. Client characteristics of ethnicity, sex, age, living situation (whether living with or away from family), and substance use severity were associated with retention in community AOD treatment. Pacific Island youth, females, 13- to 15-year olds, clients living with family, and clients with more severe substance use were generally more likely to be "engaged" with the service (ie, attended 4+ sessions) than their European and Maori, male, 16- to 19-year-old, and living away from home counterparts. These findings may inform more targeted engagement strategies in the future. PMID- 29568222 TI - Severe Myopericarditis in Diabetic Ketoacidosis-All Troponin are Not Myocardial Infarction. AB - Uncontrolled diabetes and acute coronary syndrome share a complex dynamic that results in significant ambiguity when interpreting biomarker elevations in this setting. This is concerning because myocardial infarction has been shown to be the most common cause of death in the first 24 hours of admission for uncontrolled diabetes. Literature shows that elevation in cardiac biomarkers in patients with uncontrolled diabetes could be from viral myopericarditis, although a clear clinical significance is still lacking.1 It is, however, clear that elevation in cardiac biomarkers portends a poor long-term prognosis in patients with uncontrolled diabetes mellitus. We present a rare case of myopericarditis in a middle-aged patient with uncontrolled diabetes. The patient had elevated troponin I level reaching a peak of 7.3 ng/mL with associated ST elevations on electrocardiography. Coronary angiogram was subsequently done revealing clean coronaries. To our knowledge, this is the first description of myopericarditis in uncontrolled diabetes without a known cause. PMID- 29568223 TI - Acquired von Willebrand Syndrome Complicating Nephrotic Syndrome: A Case of a Patient With Membranous Nephropathy. AB - Acquired von Willebrand syndrome (AVWS) is a rare clinical entity presenting with heterogeneous hemorrhagic manifestations, although some subsets of patients with AVWS may be asymptomatic until they are exposed to major trauma, an invasive procedure, or surgery. We herein report one such case in a 73-year-old male patient with nephrotic syndrome with a prolonged active partial thromboplastin time. We initially did not deal with this distinct abnormal clotting profile seriously, but persistent bleeding after a retroperitoneoscopic-assisted renal biopsy that allowed us to ascribe his nephrotic syndrome to membranous nephropathy fortuitously led to the discovery of concurrent AVWS. We feel that an accurate and prompt diagnosis as well as awareness of the disease remain a challenge for physicians and therefore strongly recommend the further accumulation of experiences similar to our own in a prospective manner. This report underscores the pitfalls associated with determining the bleeding risk, including an insufficient assessment and improper weighting of an abnormal clotting profile prior to the invasive procedure. Several management concerns that emerged in the current case are also discussed. PMID- 29568224 TI - Visualization of JOV abstracts. AB - Abstract: Since the abstract can be found at the beginning of most scientific articles and is an essential part of the article, several attempts have been made to explore the rhetorical moves of abstracts in various research fields. These studies dealt only with accepted articles since they can be easily accessed. Although the findings of such works have some pedagogical implications for academic writing courses for young researchers who are relatively new to their fields, they do not contribute enough to the transparency of the peer review processes conducted in research fields. Increasing transparency requires considering rejected articles since they help to clarify the decision criteria in the peer review. Based on 591 abstracts of accepted or rejected articles submitted to Journal of Visualization (JOV), the present study aimed at exploring the differences between the accepted and rejected abstracts. The results show that there are significant differences in the structures of the abstracts. Since we also successfully develop a classification model for the decision using a machine-learning technique, the findings of this study have some implications for developing a semi-automatic reviewing system that can reduce the reviewer's burden and increase the review quality. Graphical abstract: PMID- 29568225 TI - Politics of policy learning: Evaluating an experiment on free pricing arrangements in Dutch dental care. AB - In Dutch healthcare, new market mechanisms have been introduced on an experimental basis in an attempt to contain costs and improve quality. Informed by a constructivist approach, we demonstrate that such experiments are not neutral testing grounds. Drawing from semi-structured interviews and policy texts, we reconstruct an experiment on free pricing in dental care that turned into a critical example of market failure, influencing developments in other sectors. Our analysis, however, shows that (1) different market logics and (2) different experimental logics were reproduced simultaneously during the course of the experiment. We furthermore reveal how (3) evaluation and political life influenced which logics were reproduced and became taken as the lessons learned. We use these insights to discuss the role of evaluation in learning from policy experimentation and close with four questions that evaluators could ask to better understand what is learned from policy experiments, how, and why.

AB - The medical 'management' of individuals with atypical sex characteristics, or intersex variations, has been under scrutiny since the beginnings of intersex activism in the 1990s. This article explores a history of intersex surgeries in Britain and the interaction with medical and popular discourses around 'sex change' between 1930 and 1955. A focus on this period in Britain helps to critically elaborate on debates in intersex scholarship; provides historical context for the introduction of approaches and protocols based on John Money and colleagues' work in the USA in the mid-century; and analyses a long history of tension and intersection between trans and intersex experiences, treatments, politics and popular representations that continue into the present. PMID- 29568227 TI - Is there a parliamentary peace? Parliamentary veto power and military interventions from Kosovo to Daesh. AB - This article studies the effect of parliamentary involvement on security policy. Building on Democratic Peace Theory, it examines whether democracies with a parliamentary veto power are indeed less likely to participate in military interventions, than democracies without such a veto power, ceteris paribus. By studying patterns of participation across 25 to 35 countries in five military missions, this paper finds modest evidence for such a parliamentary peace and suggests that it depends on the character of the military mission in question. If a mission is framed as a test case of alliance solidarity, as was the case with OEF and the Iraq War, domestic institutional constraints can be trumped by alliance politics. If, however, countries enjoy more discretion in deciding on the use of force, domestic constraints such as parliamentary war powers have a tangible impact on government policy. PMID- 29568228 TI - Dissecting the complex regulation of lodging resistance in Brassica napus. AB - Lodging continues to be a major cause of yield loss in important crop species such as Brassica napus. Understanding the genetic regulation of lodging resistance is therefore of key interest to breeders worldwide. Current strategies aimed at minimising lodging risk involve the incorporation of dwarfing genes or the application of plant growth regulators. However, despite these efforts, lodging continues to be a persistent problem and it is therefore of high interest that novel, complimentary strategies for lodging control are implemented. One approach would be to focus on understanding the genetic properties underlying stem mechanical strength. With this in mind, we screened a training genetic diversity panel of B. napus accession for variation in stem mechanical strength and related traits. Using Associative Transcriptomics, we identified molecular markers for a suite of valuable traits. Using an independent test genetic diversity panel, we show that the methods employed are robust for identification of predictive markers. Furthermore, based on conserved synteny with Arabidopsis thaliana, we are able to provide a biological context to the marker associations detected and provide evidence for a role in pectin methylesterification in contributing to stem mechanical strength in Brassicaceae. PMID- 29568229 TI - Genetic analysis and QTL mapping of the seed hardness trait in a black common bean (Phaseolus vulgaris) recombinant inbred line (RIL) population. AB - Seed hardness trait has a profound impact on cooking time and canning quality in dry beans. This study aims to identify the unknown genetic factors and associated molecular markers to better understand and tag this trait. An F2:7 recombinant inbred line (RIL) population was derived from a cross between the hard and soft seeded black bean parents (H68-4 and BK04-001). Eighty-five RILs and the parental lines were grown at two locations in southern Manitoba during years 2014-2016. Seed samples were harvested manually at maturity to test for seed hardness traits. The hydration capacity and stone seed count were estimated by soaking the seeds overnight at room temperature following AACC method 56-35.01. Seed samples from 2016 tests were also cooked to determine effect of seed hardness on cooking quality. For mapping of genomic regions contributing to the traits, the RIL population was genotyped using the genotype by sequencing (GBS) approach. The QTL mapping revealed that in addition to the major QTL on chromosome 7 at a genomic location previously reported to affect seed-hydration, two novel QTL with significant effects were also detected on chromosomes 1 and 2. In addition, a major QTL affecting the visual appeal of cooked bean was mapped on chromosome 4. This multi-year-site study shows that despite large environmental effects, seed hardness is an oligo-genic and highly heritable trait, which is inherited independently of the cooking quality scored as visual appeal of cooked beans. The identification of the QTLs and development of SNP markers associated with seed hardness can be applied for common bean variety improvement and genetic exploitation of these traits. PMID- 29568231 TI - Birth preparedness and complication readiness among pregnant women in Tehulederie district, Northeast Ethiopia: a community-based cross-sectional study. AB - Background: Motherhood is a time of anticipation of joy for a woman, her family, and her community. In spite of this fact, it is not as enjoyable as it should be because of numerous reasons. Insufficiency or lack of birth preparedness and complication readiness is the most common reason. The aim of this study was to assess the practice of birth preparedness and complication readiness and associated factors among pregnant women in Tehuledere district, northeast Ethiopia. Methods: A community-based cross-sectional study was conducted in Tehuledere district, northeast Ethiopia. Participants were selected using the multistage sampling technique, and data were analyzed both descriptively and analytically using the binary logistic regression. Result: Out of the total 507 samples, 500 (response rate 98.6%) pregnant women participated in the study. Less than half (44.6%) and (43.4%) of the respondents had knowledge and practice on birth preparedness and complication readiness, respectively. In the multivariate analysis, knowledge of birth preparedness and complication readiness (AOR = 1.648, 95%CI: 1.073, 2.531), knowledge of danger signs during pregnancy (AOR = 2.802, 95% CI: 1.637, 4.793), gestational age (AOR = 3.379, 95% CI: 2.114, 5.401), and antenatal care follow up starting time (AOR = 2.841, 95% CI: 1.330, 6.068) were significantly associated with the practice of birth preparedness and complication readiness, but pregnant women in rural areas (AOR = 0.442, 95% CI:0.244, 0.803) were less associated with birth preparedness and complication readiness compared to women in urban settlements. Conclusion: This study identified that poor knowledge, inadequate birth preparedness, and complication readiness were prevalent among mothers in the study area. Government officials, partners, and health care providers working in the areas of maternal and child health should operate together to maximize birth preparedness and complication readiness practices. PMID- 29568230 TI - Azo group(s) in selected macrocyclic compounds. AB - Azobenzene derivatives due to their photo- and electroactive properties are an important group of compounds finding applications in diverse fields. Due to the possibility of controlling the trans-cis isomerization, azo-bearing structures are ideal building blocks for development of e.g. nanomaterials, smart polymers, molecular containers, photoswitches, and sensors. Important role play also macrocyclic compounds well known for their interesting binding properties. In this article selected macrocyclic compounds bearing azo group(s) are comprehensively described. Here, the relationship between compounds' structure and their properties (as e.g. ability to guest complexation, supramolecular structure formation, switching and motion) is reviewed. PMID- 29568232 TI - Challenges faced by nurses in using pain assessment scale in patients unable to communicate: a qualitative study. AB - Background: One helpful strategy adopted for pain management in non-verbal, intubated patients is the use of a proper pain assessment scale. The purpose of the present study is to achieve a better and deeper understanding of the existing nurses' challenges in using pain assessment scales among patients unable to communicate. Methods: This qualitative study was conducted using content analysis. Purposive sampling was used to select the participants and continued until data saturation. The participants included 20 nurses working in intensive care units. Data was collected using semi-structured interviews and analysis was done using an inductive approach. Results: Four categories and ten sub-categories were extracted from the experiences of the nurses working in the intensive care units in terms of nursing challenges in using non-verbal pain assessment scales. The four categories included "forgotten priority", "organizational barriers", "attitudinal barriers", and "barriers to knowledge". Conclusions: The findings of the present study have shown that various factors might influence on the use of non-verbal pain assessment scales in patients unable to communicate. Identifying these challenges for nurses can help take effective steps such as empowering nurses in the use of non-verbal pain assessment scales, relieving pain, and improving the quality of care services. PMID- 29568233 TI - The long non-coding RNA AK001796 contributes to tumor growth via regulating expression of p53 in esophageal squamous cell carcinoma. AB - Background: Esophageal squamous cell carcinoma (ESCC) is one of the prevalent and deadly cancers worldwide, especially in China. Considering the poor prognosis of ESCC, the aim of this study is to dissect the effects of long non-coding RNA (lncRNA) AK001796 on cell proliferation and cell cycle in vitro and tumorigenicity in vivo, providing therapeutic targets for ESCC. Methods: We conducted quantitative real time PCR to detect the expression level of lncRNA AK001796 in human ESCC tumor and adjacent non-tumor tissues, and analyzed the correlation between lncRNA AK001796 expression and clinicopathologic feature of ESCC patients. Then we knocked down the expression of lncRNA AK001796 in human ESCC cell lines Eca-109 and TE-1, and next inspected cell cycle and apoptosis condition in these cells using flow cytometry. Subsequently, we used CCK-8 assay to test proliferation ability of the lncRNA AK001796-silenced ESCC cells, and the MDM2/p53 signaling pathway in these cells was analyzed by western blot analysis. At last, the ESCC xenograft models were established to verify the role of lncRNA AK001796 on the occurrence and development of ESCC. Results: In this study, we demonstrated that lncRNA AK001796 was significantly upregulated in ESCC tumor tissues compared to adjacent non-tumor tissues. Knockdown of lncRNA AK001796 inhibited ESCC cell growth, cell cycle, and tumor growth in a xenograft mouse model via regulating MDM2/p53 signal pathway. The expression of lncRNA AK001796 was positively correlated with MDM2 levels in human ESCC samples. Conclusions: Overall, lncRNA AK001796 regulates cell proliferation and cell cycle via modulating MDM2/p53 signaling in ESCC, which provides a new insight into the treatment targets for ESCC.Trial registration This study was registrated in the Ethics Committee of the First Affiliated Hospital of Nanjing Medical University (Trial registration: 2012-SR-127, Registered 20 January 2012). PMID- 29568234 TI - Downregulation of microRNA-21 inhibited radiation-resistance of esophageal squamous cell carcinoma. AB - Background: MicroRNA-21 (miR-21) was previously reported being dysregulated in many kinds of cancer including esophageal squamous cell carcinoma (ESCC). In the present study, we aimed to investigate the role of miR-21 in ESCC, especially in its effects on radiation-sensitivity of ESCC. Methods: Expression of miR-21 was detected in 63 pairs ESCC tumor and adjacent non-tumoral tissues using qRT-PCR, correlation between miR-21 and clinicopathological feature of ESCC was analyzed. The role of miR-21 in the proliferation, cell cycle and apoptosis of ESCC cells during irradiation were studied. Results: MicroRNA-21 expression was significantly increased in ESCC tumor tissues. Expression of miR-21 was positively associated with advanced clinical stage. Under irradiation, overexpression of miR-21 increased cell proliferation and cells in S phase, and inhibited cell apoptosis of ESCC cells. In contrast, knockdown of miR-21 had an opposite effect. Conclusions: Downregulation of miR-21 inhibited the radiation resistance of ESCC, whereas overexpression of miR-21 increased the radiation resistance. MiR-21 is a potential novel target for developing specific treatment interventions in ESCC in future. PMID- 29568235 TI - Transcription factor E2F3a regulates CASP8AP2 transcription and enhances sensitivity to chemotherapeutic drugs in acute lymphoblastic leukemia. AB - Background: Low expression of E2F3a and caspase 8 associated protein 2 (CASP8AP2) are associated with poor prognosis of childhood acute lymphoblastic leukemia (ALL). Methods: Dual-luciferase reporter assay and wild type as well as four mutated types of reporter plasmids were used to demonstrate the activation of E2F3a on CASP8AP2 transcription. The direct binding of E2F3a with the promoter of CASP8AP2 was shown by Chromatin Immunoprecipitation (ChIP). Cell proliferation activity and cell cycle were determined by MTS and flow cytometry in leukemic cells after treating with common chemotherapeutic drugs vincristine and daunorubicin. Results: In this study, we found that up-regulation of E2F3a in leukemic cells led to increased fraction of cells in S and G2/M phase, accelerated proliferation, and enhanced sensitivity to vincristine and daunorubicin. ChIP and luciferase assay indicated that E2F3a could directly bind to two fragments in the wild type of CASP8AP2 promotor (- 206 to - 69 and - 677 to - 507), and activate its transcription activity which was reduced in mutated promotors. The effect of E2F3a on chemotherapeutic sensitivity of leukemic cells could be reversed by down-regulating CASP8AP2. Conclusions: E2F3a could promote transcription and expression of CASP8AP2. The effect of E2F3a on chemotherapeutic sensitivity of ALL cells was implemented by regulating CASP8AP2 expression to a great extent. PMID- 29568236 TI - Alteration of metabolite profiling by cold atmospheric plasma treatment in human myeloma cells. AB - Background: Despite new progress of chemotherapy in multiple myeloma (MM) clinical treatment, MM is still a refractory disease and new technology is needed to improve the outcomes and prolong the survival. Cold atmospheric plasma is a rapidly developed technology in recent years, which has been widely applied in biomedicine. Although plasma could efficiently inactivate various tumor cells, the effects of plasma on tumor cell metabolism have not been studied yet. Methods: In this study, we investigated the metabolite profiling of He plasma treatment on myeloma tumor cells by gas-chromatography time-of-flight (GC-TOF) mass-spectrometry. Meanwhile, by bioinformatic analysis such as GO and KEGG analysis we try to figure out the metabolism pathway that was significantly affected by gas plasma treatment. Results: By GC-TOF mass-spectrometry, 573 signals were detected and evaluated using PCA and OPLS-DA. By KEGG analysis we listed all the differential metabolites and further classified into different metabolic pathways. The results showed that beta-alanine metabolism pathway was the most significant change after He gas plasma treatment in myeloma cells. Besides, propanoate metabolism and linoleic acid metabolism should also be concerned during gas plasma treatment of cancer cells. Conclusions: Cold atmospheric plasma treatment could significantly alter the metabolite profiling of myeloma tumor cells, among which, the beta-alanine metabolism pathway is the most susceptible to He gas plasma treatment. PMID- 29568238 TI - In comparative perspective: The effects of incarceration abroad on penal subjectivity among prisoners in Lithuania. AB - This article looks at how global flows of people and policies affect penal subjectivity among prisoners in Lithuania. Those who had previously been incarcerated abroad perceive their punishment in Lithuania's reforming penal system in comparative terms. We find that international prison experience may either diminish or increase the sense of the severity of the current punishment. Respondents often felt more comfortable in a familiar culture of punishment in Lithuania that emphasizes autonomy and communality. Moreover, internationalized prisoners perceive prison reform emulating West European models as a threat to this culture and are able to articulate comparative critiques of this reform and contest its effects. PMID- 29568237 TI - Resistance a major hindrance to chemotherapy in hepatocellular carcinoma: an insight. AB - Hepatocellular carcinoma (HCC) is one of the leading causes of cancer mortality, accounting for almost 90% of total liver cancer burden. Surgical resection followed by adjuvant and systemic chemotherapy are the most meticulously followed treatment procedures but the complex etiology and high metastatic potential of the disease renders surgical treatment futile in majority of the cases. Another hindrance to the scenario is the acquired resistance to drugs resulting in relapse of the disease. Hence, to provide insights into development of novel therapeutic targets and diagnostic biomarkers, this review focuses on the various molecular mechanisms underlying chemoresistance in HCC. We have provided a comprehensive summary of the various strategies adopted by HCC cells, extending from apoptosis evasion, autophagy activation, drug expulsion to epigenetic transformation as modes of therapy resistance. The role of stem cells in imparting chemoresistance is also discussed. Furthermore, the review also focuses on how this knowledge might be exploited for the development of an effective, prospective therapy against HCC. PMID- 29568239 TI - Effects of the complete replacement of fish oil with linseed oil on growth, fatty acid composition, and protein expression in the Chinese mitten crab (Eriocheir sinensis). AB - Background: The finite marine resources make it difficult for us to obtain enough fish oil (FO) used in aquatic feeds. Another sustainable ingredients should be found to substitute FO. The effects of replacing FO with vegetable oil have been studied in a variety of crustaceans, but most studies have focused on the phenotypic effects. Little is known about the mechanisms of the effects. Methods: To understand the molecular responses during the replacement of FO in Eriocheir sinensis, we investigated the effects of feeding FO or linseed oil (LO) on growth performance, digestive enzyme activity, fatty acid composition and protein expression in E. sinensis. Twenty-four juvenile crabs were fed diets containing FO or LO for 112 days. Weight, carapace length and width were recorded. Fatty acid composition of the diets and the hepatopancreas and protein expression in the hepatopancreas were analyzed. Results: Growth performance and molting interval were unchanged by diet. Crabs fed FO and LO had same activity of lipase and amylase, but comparing with crabs fed LO, crabs fed FO had higher trypsin activity and lower pepsin activity. Hepatopancreas fatty acid composition changed to reflect the fatty acid composition of the diets. In total, 194 proteins were differentially expressed in the hepatopancreas between the diets. Expression of heat shock proteins was higher in crabs fed LO. Expression of fatty acid synthase, long-chain fatty acid transport protein 4, acyl-CoA delta-9 desaturase, and fatty acid-binding protein 1, was higher in crabs fed FO. Conclusions: The substitution of FO with LO didn't have any effects on the growth and molting of mitten crab, but could significantly decrease the ability of mitten crab to cope with stress. The high content of HUFAs in the hepatopancreas of mitten crab fed FO is due to the high abundance of the proteins relative to the transport of the HUFAs. These findings provide a reason of the high content of EPA and DHA in crabs fed with FO, and provide new information for the replacement of FO in diets of mitten crab. PMID- 29568240 TI - Differential impact of diabetes mellitus on antiplatelet effects of prasugrel and clopidogrel. AB - Background: Although prasugrel exerts stronger antiplatelet effects compared with clopidogrel, the factors affecting platelet reactivity under prasugrel have not been fully determined. This study aimed to find the novel mechanistic differences between two thienopyridines and identify the factor that influence platelet reactivity to each drug. Methods: Forty patients with stable angina who underwent elective percutaneous coronary intervention were randomly assigned to receive either prasugrel (20 mg) or clopidogrel (300 mg) as a loading dose. Platelet function (light transmission, laser light scattering, and vasodilator-stimulated phosphoprotein phosphorylation) and plasma active metabolite levels were measured after the loading dose. Results: Prasugrel consistently inhibited adenosine diphosphate receptor P2Y12 signalling to abolish amplification of platelet aggregation. Prasugrel abolished even small platelet aggregates composed of less than 100 platelets. On the other hand, clopidogrel inhibited large aggregates but increased small and medium platelet aggregates. Diabetes was the only independent variable for determining antiplatelet effects and active metabolite concentration of prasugrel, but not clopidogrel. Sleep-disordered breathing was significantly correlated with platelet reactivity in patients who had clopidogrel. Conclusions: Prasugrel efficiently abolishes residual P2Y12 signalling that causes small platelet aggregates, but these small aggregates are not inhibited by clopidogrel. Considering the differential effect of diabetes on antiplatelet effects between these two drugs, the pharmacokinetics of prasugrel, other than cytochrome P450 metabolism, might be affected by diabetes.

AB - This group case study describes the course of a 14-session Cognitive Behavioral Therapy (CBT) for Latino adolescents with Type 1 Diabetes Mellitus (T1DM) and depressive symptoms. The intervention, known as CBT-DM, is an adaptation of an efficacious group intervention for adolescent depression. The treatment rationale and cultural adaption model are described as well as procedures used to achieve sensitivity to the characteristics of the T1DM culture as experienced by Latino youth from Puerto Rico. Session-by-session protocol is reviewed and treatment gains on the group as a whole and on its individual members are presented, providing quantitative and qualitative data. Treatment feasibility, clients' acceptance and satisfaction with treatment, and follow-up data up to 6 months post-treatment are also examined, considering cognitive, behavioral, emotional, relational, medical, and functional outcomes. Complicating factors, barriers to care, and treatment implications are discussed in the context of treating clients with comorbid chronic physical illness and emotional problems also embedded in a Latino culture. Translation of evidence-based treatments for depression into primary care settings and adapting protocols to youth populations with other medical illnesses is proposed. Recommendations for clinicians are provided, emphasizing the establishment of collaborative relationships with clients, assessing their stage in the process of accepting their chronic illness, as well as understanding their overall context to avoid unnecessary attributions of pathology to their thoughts, behaviors, and feelings. PMID- 29568242 TI - R2GUESS: A Graphics Processing Unit-Based R Package for Bayesian Variable Selection Regression of Multivariate Responses. AB - Technological advances in molecular biology over the past decade have given rise to high dimensional and complex datasets offering the possibility to investigate biological associations between a range of genomic features and complex phenotypes. The analysis of this novel type of data generated unprecedented computational challenges which ultimately led to the definition and implementation of computationally efficient statistical models that were able to scale to genome-wide data, including Bayesian variable selection approaches. While extensive methodological work has been carried out in this area, only few methods capable of handling hundreds of thousands of predictors were implemented and distributed. Among these we recently proposed GUESS, a computationally optimised algorithm making use of graphics processing unit capabilities, which can accommodate multiple outcomes. In this paper we propose R2GUESS, an R package wrapping the original C++ source code. In addition to providing a user-friendly interface of the original code automating its parametrisation, and data handling, R2GUESS also incorporates many features to explore the data, to extend statistical inferences from the native algorithm (e.g., effect size estimation, significance assessment), and to visualize outputs from the algorithm. We first detail the model and its parametrisation, and describe in details its optimised implementation. Based on two examples we finally illustrate its statistical performances and flexibility.

AB - Background: Obesity is a primary factor of lifestyle-related diseases, and the age of its onset has decreased. The reactive oxygen species (ROS), the superoxide anion, is generated in the mitochondrial electron transport chain and the damage it induces in cells may be a contributing factor to obesity-related lifestyle diseases. In the present study, the influence of the ingestion of a high-fat diet (HFD) on superoxide anion generation in rat liver mitochondria (Mt) and membrane fluidity was investigated. Methods: Male Wistar rats were fed a normal diet (ND, n = 6) or HFD (n = 6). Liver Mt were isolated and oxygen consumption, superoxide anion production (the adrenaline method), and membrane fluidity (the spin label method) were measured. Results: After 11 weeks, body weights and abdominal circumferences were higher in the HFD group than in the ND group. Mt oxygen consumption was higher in the HFD group than in the ND group. Superoxide anion production was significantly lower in the HFD group than in the ND group, while no significant changes were observed in membrane fluidity. Conclusion: Although rats developed diet-induced obesity, it did not reach the level of disease development. The promotion of lipid metabolism appeared to reduce superoxide anion production, but did not influence membrane fluidity. While superoxide anion damages cells as an oxidative stress, ROS and superoxide dismutase are essential signaling molecules in the body. The present results suggest that the continuous ingestion of a HFD impairs Mt and induces disease development.

AB - Perfluorooctyl bromide (PFOB) enclosed nanoparticles (NPs) as ultrasonic contrasts have shown promising results in the recent years. However, NPs display poor contrast enhancement in vivo. In this work, we used the copolymers poly(lactide-co-glycolide) carboxylic acid (PLGA-COOH) and poly(lactide-co- glycolide) poly(ethylene glycol) carboxylic acid (PLGA-PEG-COOH) as a shell to encapsulate PFOB to prepare a nanoultrasonic contrast agent. The NPs were small and uniform (210.6 +/- 2.9 nm with a polydispersity index of 0.129 +/- 0.016) with a complete shell nuclear structure under the transmission electron microscopy (TEM). In vitro, when concentration of NPs was >=10 mg/ml and clinical diagnostic frequency was >=9 MHz, NPs produced intensive enhancement of ultrasonic gray-scale signals. NPs could produce stable and obvious gray enhancement with high mechanical index (MI) (MI > 0.6). In vivo, the NPs offered good ultrasound enhancement in tumor after more than 24 h and optical imaging also indicated that NPs were mainly located at tumor site. Subsequent analysis confirmed that large accumulation of fluorescence was observed in the frozen section of the tumor tissue. All these results caused the conclusion that NPs encapsulated PFOB has achieved tumor-selective imaging in vivo.

AB - Introduction: Contemporary metabolomic fingerprinting is based on multiple spectrometric and chromatographic signals, used either alone or combined with structural and chemical information of metabolic markers at the qualitative and semiquantitative level. However, signal shifting, convolution, and matrix effects may compromise metabolomic patterns. Recent increase in the use of qualitative metabolomic data, described by the presence (1) or absence (0) of particular metabolites, demonstrates great potential in the field of metabolomic profiling and fingerprint analysis. Objectives: The aim of this study is a comprehensive evaluation of binary similarity measures for the elucidation of patterns among samples of different botanical origin and various metabolomic profiles. Methods: Nine qualitative metabolomic data sets covering a wide range of natural products and metabolomic profiles were applied to assess 44 binary similarity measures for the fingerprinting of plant extracts and natural products. The measures were analyzed by the novel sum of ranking differences method (SRD), searching for the most promising candidates. Results: Baroni-Urbani-Buser (BUB) and Hawkins-Dotson (HD) similarity coefficients were selected as the best measures by SRD and analysis of variance (ANOVA), while Dice (Di1), Yule, Russel-Rao, and Consonni Todeschini 3 ranked the worst. ANOVA revealed that concordantly and intermediately symmetric similarity coefficients are better candidates for metabolomic fingerprinting than the asymmetric and correlation based ones. The fingerprint analysis based on the BUB and HD coefficients and qualitative metabolomic data performed equally well as the quantitative metabolomic profile analysis. Conclusion: Fingerprint analysis based on the qualitative metabolomic profiles and binary similarity measures proved to be a reliable way in finding the same/similar patterns in metabolomic data as that extracted from quantitative data. PMID- 29568244 TI - Herbal medicine for sports: a review. AB - The use of herbal medicinal products and supplements has increased during last decades. At present, some herbs are used to enhance muscle strength and body mass. Emergent evidence suggests that the health benefits from plants are attributed to their bioactive compounds such as Polyphenols, Terpenoids, and Alkaloids which have several physiological effects on the human body. At times, manufacturers launch numerous products with banned ingredient inside with inappropriate amounts or fake supplement inducing harmful side effect. Unfortunately up to date, there is no guarantee that herbal supplements are safe for anyone to use and it has not helped to clear the confusion surrounding the herbal use in sport field especially. Hence, the purpose of this review is to provide guidance on the efficacy and side effect of most used plants in sport. We have identified plants according to the following categories: Ginseng, alkaloids, and other purported herbal ergogenics such as Tribulus Terrestris, Cordyceps Sinensis. We found that most herbal supplement effects are likely due to activation of the central nervous system via stimulation of catecholamines. Ginseng was used as an endurance performance enhancer, while alkaloids supplementation resulted in improvements in sprint and cycling intense exercises. Despite it is prohibited, small amount of ephedrine was usually used in combination with caffeine to enhance muscle strength in trained individuals. Some other alkaloids such as green tea extracts have been used to improve body mass and composition in athletes. Other herb (i.e. Rhodiola, Astragalus) help relieve muscle and joint pain, but results about their effects on exercise performance are missing.

Up to 80% of pancreatic cancer patients present with either new-onset type 2 diabetes or impaired glucose tolerance at the time of diagnosis. Recent literature suggests that diabetes mellitus type 2 is a risk factor, a manifestation and a prognostic factor for pancreatic cancer. This article is intended to clarify the evidence about diabetes as a risk factor for pancreatic cancer. PMID- 29568249 TI - Challenges of pheromone-based mating disruption of Cydia strobilella and Dioryctria abietella in spruce seed orchards. AB - Seed orchards function as the primary source of high-quality seeds for reforestation in many European countries, but their seed yields can be severely reduced due to seed- and cone-feeding insects. We evaluated various parameters of pheromone-based mating disruption for control of the moths Cydia strobilella and Dioryctria abietella, which are major pests in European Picea abies seed orchards. We applied different types of pheromone dispensers (rubber septa or wax droplets) at different densities and heights, and with different amounts of active components, covering whole orchards or part of an orchard. The efficacy of the treatment was evaluated by analysing male captures in pheromone-baited assessment traps, and presence of larvae in cones. A dramatic decrease (94-100%) in capture of males in traps occurred in all pheromone-treated plots compared to control plots for both moth species. In contrast, a subsequent reduction in larval numbers in cones was only achieved when wax droplets were used as the dispensing formulation at high density and at the highest pheromone dose tested, and only in half of the trials for each pest species. Electrophysiological recordings using antennae of male C. strobilella indicated elevated pheromone concentrations in a treated plot versus a control plot. Our results show that mating disruption has potential to reduce cone damage in spruce seed orchards caused by C. strobilella and D. abietella, but optimisation of the technique is required to achieve consistent and efficient population suppression of these pests. PMID- 29568248 TI - Sterile insect technique and Wolbachia symbiosis as potential tools for the control of the invasive species Drosophila suzukii. AB - Drosophila suzukii, a vinegar fly originated from Southeast Asia, has recently invaded western countries, and it has been recognized as an important threat of a wide variety of several commercial soft fruits. This review summarizes the current information about the biology and dispersal of D. suzukii and discusses the current status and prospects of control methods for the management of this pest. We highlight current knowledge and ongoing research on innovative environmental-friendly control methods with emphasis on the sterile insect technique (SIT) and the incompatible insect technique (IIT). SIT has been successfully used for the containment, suppression or even eradication of populations of insect pests. IIT has been proposed as a stand-alone tool or in conjunction with SIT for insect pest control. The principles of SIT and IIT are reviewed, and the potential value of each approach in the management of D. suzukii is analyzed. We thoroughly address the challenges of SIT and IIT, and we propose the use of SIT as a component of an area-wide integrated pest management approach to suppress D. suzukii populations. As a contingency plan, we suggest a promising alternative avenue through the combination of these two techniques, SIT/IIT, which has been developed and is currently being tested in open-field trials against Aedes mosquito populations. All the potential limiting factors that may render these methods ineffective, as well as the requirements that need to be fulfilled before their application, are discussed. PMID- 29568250 TI - Dietary yeast affects preference and performance in Drosophila suzukii. AB - Yeasts play an important role in nutrition physiology and host attraction of many Drosophila species, and associations with various yeast species are documented for several drosophilid flies. The pest Drosophila suzukii (Matsumura) has a predominant association with the yeast Hanseniaspora uvarum. However, research has not been conducted on the nutritional physiology of the yeasts associated with D. suzukii (spotted wing drosophila). Therefore, in this study, we determined whether dietary yeast was nutritionally relevant and whether yeast species closely associated with D. suzukii positively affected life-history traits. Our results confirm a crucial role of dietary yeast in the larval development and survival of D. suzukii. Furthermore, we found specific effects of the closely associated yeast species H. uvarum and Candida sp. on larval survival. Observations of the egg-laying behaviour of D. suzukii on cherry fruits artificially colonised with different yeast species revealed that the number of eggs laid increased on fruits colonised with Candida sp. and Saccharomyces cerevisiae. PMID- 29568251 TI - Infection of Drosophila suzukii with the obligate insect-pathogenic fungus Entomophthora muscae. AB - Physiological constraints restrict specialist pathogens from infecting new hosts. From an applied perspective, a narrow host range makes specialist pathogens interesting for targeting specific pest insects since they have minimal direct effects on non-target species. Entomopathogenic fungi of the genus Entomophthora are dipteran-specific but have not been investigated for their ability to infect the spotted wing drosophila (SWD; Drosophila suzukii) a fruit-damaging pest invasive to Europe and America. Our main goal was to study whether SWD is in the physiological host range of the entomophthoralean species E. muscae. We investigated pathogenicity and virulence of E. muscae towards its main natural host, the housefly Musca domestica, and towards SWD. We found that E. muscae readily infected and significantly reduced survival of SWD by 27.3% with the majority of flies dying 4-8 days post-exposure. In comparison with SWD, infection of the natural host M. domestica resulted in an even higher mortality of 62.9% and larger conidial spores of E. muscae, reflecting the physiological constraints of the pathogen in the atypical host. We demonstrated that pathogens of the E. muscae species complex that typically have a narrow natural host range of one or few dipteran species are able to infect SWD, and we described a new method for in vivo transmission and infection of an entomophthoralean fungus to SWD. PMID- 29568252 TI - Insect pathogenic fungi and bed bugs: behaviour, horizontal transfer and the potential contribution to IPM solutions. AB - The increasing problem of bed bugs requires the development of new control strategies, and insect pathogenic fungi can contribute towards management. We used laboratory bioassays with Isaria fumosoroseus, Lecanicillium muscarium and Beauveria bassiana to evaluate their virulence to the bed bug. Only B. bassiana significantly affected bed bug survival and was dependent on dose and formulation. A 2% B. bassiana oil formulation induced horizontal transfer to elevate mortality in a 10-day arena bioassay. Temporal distribution of contagious individuals and increasing the dose from 2 to 4% did not increase mortality. Horizontal transfer mainly occurred between adults, and only partly between adults and nymphs. Bed bugs showed activity peaks during the night, and activity was increased by elevated levels of CO2. Distribution between harbourages was not affected by CO2 activation, level of infection or the bio-pesticide, and horizontal transfer was not dependent on the degree of aggregation. Movement in the arenas negatively affected horizontal transfer when the number of susceptible individuals was large. Level of infection also influenced behaviour as the bed bug movement increased with elevated disease burden. The use of fungi as a part of an integrated pest management strategy seems to be an interesting option that should be investigated further. B. bassiana kills bed bugs and can be carried to harbourages to target hidden individuals. PMID- 29568253 TI - Feasibility and safety of total laparoscopic hysterectomy for huge uteri without the use of uterine manipulator: description of emblematic cases. AB - Background: Uterine manipulator is a very useful tool in performing total laparoscopic hysterectomy (TLH) for large uteri; however, in some cases, it cannot be used due to unfavorable anatomical conditions. The feasibility and safety of TLH for very large uteri without the use of uterine manipulator has not yet been established. Results: We describe two emblematic cases of TLH for huge fibromatous uteri: the first one for a uterus weighing 5700 g, which is the largest uterus laparoscopically removed to date reported in literature, and the second one for a uterus of 3670 g associated with a severe lymph node neoplastic disease.In both cases, TLH was successfully and safely performed even without the use of uterine manipulator, thus allowing a rapid recovery, especially in the second case, which was essential for a fast start of the most appropriate oncological treatment, the best quality of life and undoubtedly cosmetic advantages. Conclusions: Although we believe in the great usefulness of the uterine manipulator in performing TLH for huge uteri, in the present paper, we demonstrate the feasibility and safety of such complex surgery also when the use of this tool is not possible due to unfavorable anatomical condition. PMID- 29568254 TI - Implementation of laparoscopic hysterectomy for endometrial cancer over the past decade. AB - Background: Laparoscopic hysterectomy (LH) for the treatment of early-stage endometrial carcinoma/cancer (EC) has demonstrated to be safe in several randomized controlled trials. Yet, data on implementation of LH in clinical practice are limited. In the present study, implementation of LH for EC was evaluated in a large oncology network in the Netherlands. Results: Retrospectively, a total of 556 EC patients with FIGO stage I-II were registered in the selected years. The proportion of LH gradually increased from 11% in 2006 to 85% in 2015. LH was more often performed in patients with low-grade EC and was not related to the studied patient characteristics. The introduction of TLH was frequently preceded by LAVH. Patients treated in teaching hospitals were more likely to undergo a LH compared to patients in non-teaching hospitals. The conversion rate was 7.7%, and the overall complication rates between LH and AH were comparable, but less postoperative complications in LH. Conclusions: Implementation of laparoscopic hysterectomy for early-stage EC increased from 11 to 85% in 10 years. Implementation of TLH was often preceded by LAVH and was faster in teaching hospitals. PMID- 29568255 TI - Oligosaccharide model of the vascular endothelial glycocalyx in physiological flow. AB - Experiments have consistently revealed the pivotal role of the endothelial glycocalyx layer in vasoregulation and the layer's contribution to mechanotransduction pathways. However, the exact mechanism by which the glycocalyx mediates fluid shear stress remains elusive. This study employs atomic scale molecular simulations with the aim of investigating the conformational and orientation properties of highly flexible oligosaccharide components of the glycocalyx and their suitability as transduction molecules under hydrodynamic loading. Fluid flow was shown to have nearly no effect on the conformation populations explored by the oligosaccharide, in comparison with static (diffusion) conditions. However, the glycan exhibited a significant orientation change, when compared to simple diffusion, aligning itself with the flow direction. It is the tethered end of the glycan, an asparagine amino acid, which experienced conformational changes as a result of this flow-induced bias. Our results suggest that shear flow through the layer can have an impact on the conformational properties of saccharide-decorated transmembrane proteins, thus acting as a mechanosensor. PMID- 29568256 TI - Space-time structure and wavevector anisotropy in space plasma turbulence. AB - Space and astrophysical plasmas often develop into a turbulent state and exhibit nearly random and stochastic motions. While earlier studies emphasize more on understanding the energy spectrum of turbulence in the one-dimensional context (either in the frequency or the wavenumber domain), recent achievements in plasma turbulence studies provide an increasing amount of evidence that plasma turbulence is essentially a spatially and temporally evolving phenomenon. This review presents various models for the space-time structure and anisotropy of the turbulent fields in space plasmas, or equivalently the energy spectra in the wavenumber-frequency domain for the space-time structures and that in the wavevector domain for the anisotropies. The turbulence energy spectra are evaluated in different one-dimensional spectral domains; one speaks of the frequency spectra in the spacecraft observations and the wavenumber spectra in the numerical simulation studies. The notion of the wavenumber-frequency spectrum offers a more comprehensive picture of the turbulent fields, and good models can explain the one-dimensional spectra in the both domains at the same time. To achieve this goal, the Doppler shift, the Doppler broadening, linear-mode dispersion relations, and sideband waves are reviewed. The energy spectra are then extended to the wavevector domain spanning the directions parallel and perpendicular to the large-scale magnetic field. By doing so, the change in the spectral index at different projections onto the one-dimensional spectral domain can be explained in a simpler way. PMID- 29568257 TI - Characterization of Diffusion Metric Map Similarity in Data From a Clinical Data Repository Using Histogram Distances. AB - As the sharing of data is mandated by funding agencies and journals, reuse of data has become more prevalent. It becomes imperative, therefore, to develop methods to characterize the similarity of data. While users can group data based on the acquisition parameters stored in the file headers, these gives no indication whether a file can be combined with other data without increasing the variance in the data set. Methods have been implemented that characterize the signal-to-noise ratio or identify signal drop-outs in the raw image files, but potential users of data often have access to calculated metric maps and these are more difficult to characterize and compare. Here we describe a histogram-distance based method applied to diffusion metric maps of fractional anisotropy and mean diffusivity that were generated using data extracted from a repository of clinically-acquired MRI data. We describe the generation of the data set, the pitfalls specific to diffusion MRI data, and the results of the histogram distance analysis. We find that, in general, data from GE scanners are less similar than are data from Siemens scanners. We also find that the distribution of distance metric values is not Gaussian at any selection of the acquisition parameters considered here (field strength, number of gradient directions, b value, and vendor). PMID- 29568258 TI - Using a Double-Coil TMS Protocol to Assess Preparatory Inhibition Bilaterally. AB - Transcranial magnetic stimulation (TMS) applied over the primary motor cortex (M1), elicits motor-evoked potentials (MEPs) in contralateral limb muscles which are valuable indicators of corticospinal excitability (CSE) at the time of stimulation. So far, most studies have used single-coil TMS over one M1, yielding MEPs in muscles of a single limb-usually the hand. However, tracking CSE in the two hands simultaneously would be useful in many contexts. We recently showed that, in the resting state, double-coil stimulation of the two M1 with a 1 ms inter-pulse interval (double-coil1 ms TMS) elicits MEPs in both hands that are comparable to MEPs obtained using single-coil TMS. To further evaluate this new technique, we considered the MEPs elicited by double-coil1 ms TMS in an instructed-delay choice reaction time task where a prepared response has to be withheld until an imperative signal is displayed. Single-coil TMS studies have repetitively shown that in this type of task, the motor system is transiently inhibited during the delay period, as evident from the broad suppression of MEP amplitudes. Here, we aimed at investigating whether a comparable inhibitory effect can be observed with MEPs elicited using double-coil1 ms TMS. To do so, we compared the amplitude as well as the coefficient of variation (CV) of MEPs produced by double-coil1 ms or single-coil TMS during action preparation. We observed that MEPs were suppressed (smaller amplitude) and often less variable (smaller CV) during the delay period compared to baseline. Importantly, these effects were equivalent whether single-coil or double-coil1 ms TMS was used. This suggests that double-coil1 ms TMS is a reliable tool to assess CSE, not only when subjects are at rest, but also when they are involved in a task, opening new research horizons for scientists interested in the corticospinal correlates of human behavior. PMID- 29568259 TI - Auditory Proprioceptive Integration: Effects of Real-Time Kinematic Auditory Feedback on Knee Proprioception. AB - The purpose of the study was to assess the influence of real-time auditory feedback on knee proprioception. Thirty healthy participants were randomly allocated to control (n = 15), and experimental group I (15). The participants performed an active knee-repositioning task using their dominant leg, with/without additional real-time auditory feedback where the frequency was mapped in a convergent manner to two different target angles (40 and 75 degrees ). Statistical analysis revealed significant enhancement in knee re-positioning accuracy for the constant and absolute error with real-time auditory feedback, within and across the groups. Besides this convergent condition, we established a second divergent condition. Here, a step-wise transposition of frequency was performed to explore whether a systematic tuning between auditory-proprioceptive repositioning exists. No significant effects were identified in this divergent auditory feedback condition. An additional experimental group II (n = 20) was further included. Here, we investigated the influence of a larger magnitude and directional change of step-wise transposition of the frequency. In a first step, results confirm the findings of experiment I. Moreover, significant effects on knee auditory-proprioception repositioning were evident when divergent auditory feedback was applied. During the step-wise transposition participants showed systematic modulation of knee movements in the opposite direction of transposition. We confirm that knee re-positioning accuracy can be enhanced with concurrent application of real-time auditory feedback and that knee re positioning can modulated in a goal-directed manner with step-wise transposition of frequency. Clinical implications are discussed with respect to joint position sense in rehabilitation settings. PMID- 29568260 TI - Event-Related Potential Responses to Task Switching Are Sensitive to Choice of Spatial Filter. AB - Event-related potential (ERP) studies using the task-switching paradigm show that multiple ERP components are modulated by activation of proactive control processes involved in preparing to repeat or switch task and reactive control processes involved in implementation of the current or new task. Our understanding of the functional significance of these ERP components has been hampered by variability in their robustness, as well as their temporal and scalp distribution across studies. The aim of this study is to examine the effect of choice of reference electrode or spatial filter on the number, timing and scalp distribution of ERP elicited during task-switching. We compared four configurations, including the two most common (i.e., average mastoid reference and common average reference) and two novel ones that aim to reduce volume conduction (i.e., reference electrode standardization technique (REST) and surface Laplacian) on mixing cost and switch cost effects in cue-locked and target-locked ERP waveforms in 201 healthy participants. All four spatial filters showed the same well-characterized ERP components that are typically seen in task switching paradigms: the cue-locked switch positivity and target-locked N2/P3 effect. However, both the number of ERP effects associated with mixing and switch cost, and their temporal and spatial resolution were greater with the surface Laplacian transformation which revealed rapid temporal adjustments that were not identifiable with other spatial filters. We conclude that the surface Laplacian transformation may be more suited to characterize EEG signatures of complex spatiotemporal networks involved in cognitive control. PMID- 29568261 TI - 8-O-Acetyl Shanzhiside Methylester From Lamiophlomis Rotata Reduces Neuropathic Pain by Inhibiting the ERK/TNF-alpha Pathway in Spinal Astrocytes. AB - Lamiophlomis rotata (L. rotata; Benth.) Kudo is an effective traditional herb in the clinical treatment of chronic pain syndromes in China. 8-O-acetyl shanzhiside methylester (8-OaS), a chief component in L. rotata, possesses potent immunosuppressive activities and favorable analgesic effects. This study was proposed to compare the analgesic effects of 8-OaS with those of lidocaine and ketamine in a spinal nerve ligation (SNL) model by behavioral tests, and then investigated its effects upon the expression of spinal glial fibrillary acidic protein (GFAP), phosphorylated extracellular regulated protein kinases (pERK) and tumor necrosis factor-alpha (TNF-alpha) via immunofluorescence staining and western blot analyses. The data showed consecutive intrathecal injection of 8-OaS for 2 weeks brought about remarkable palliation of neuropathic pain (NP), possessing similar anti-allodynia effects with those of lidocaine and ketamine. Two weeks after surgery, pERK within the spinal dorsal horn was mainly expressed in astrocytes more than neurons and microglia, and 8-OaS inhibited spinal astrocytic activation and TNF-alpha expression. Finally, co-treatment of 8-OaS and PD98059 (an Extracellular signal-regulated kinase, ERK inhibitor) did not lead to remarkable increase in pain relief or TNF-alpha expression comparing to rats treated with 8-OaS or PD98059 alone. In conclusion, the anti-nociceptive effects of 8-OaS in the condition of NP relied on the inhibition of SNL-induced astrocyte activation, probably via the down-regulation of the ERK/TNF-alpha pathway. PMID- 29568263 TI - Neuroanatomy from Mesoscopic to Nanoscopic Scales: An Improved Method for the Observation of Semithin Sections by High-Resolution Scanning Electron Microscopy. AB - Semithin sections are commonly used to examine large areas of tissue with an optical microscope, in order to locate and trim the regions that will later be studied with the electron microscope. Ideally, the observation of semithin sections would be from mesoscopic to nanoscopic scales directly, instead of using light microscopy and then electron microscopy (EM). Here we propose a method that makes it possible to obtain high-resolution scanning EM images of large areas of the brain in the millimeter to nanometer range. Since our method is compatible with light microscopy, it is also feasible to generate hybrid light and electron microscopic maps. Additionally, the same tissue blocks that have been used to obtain semithin sections can later be used, if necessary, for transmission EM, or for focused ion beam milling and scanning electron microscopy (FIB-SEM). PMID- 29568262 TI - Dynamical Mechanism of Hyperpolarization-Activated Non-specific Cation Current Induced Resonance and Spike-Timing Precision in a Neuronal Model. AB - Hyperpolarization-activated cyclic nucleotide-gated cation current (Ih ) plays important roles in the achievement of many physiological/pathological functions in the nervous system by modulating the electrophysiological activities, such as the rebound (spike) to hyperpolarization stimulations, subthreshold membrane resonance to sinusoidal currents, and spike-timing precision to stochastic factors. In the present paper, with increasing gh (conductance of Ih ), the rebound (spike) and subthreshold resonance appear and become stronger, and the variability of the interspike intervals (ISIs) becomes lower, i.e., the enhancement of spike-timing precision, which are simulated in a conductance-based theoretical model and well explained by the nonlinear concept of bifurcation. With increasing gh , the stable node to stable focus, to coexistence behavior, and to firing via the codimension-1 bifurcations (Hopf bifurcation, saddle-node bifurcation, saddle-node bifurcations on an invariant circle, and saddle homoclinic orbit) and codimension-2 bifurcations such as Bogdanov-Takens (BT) point related to the transition between saddle-node and Hopf bifurcations, are acquired with 1- and 2-parameter bifurcation analysis. The decrease of variability of ISIs with increasing gh is induced by the fast decrease of the standard deviation of ISIs, which is related to the increase of the capacity of resisting noisy disturbance due to the firing becomes far away from the bifurcation point. The enhancement of the rebound (spike) with increasing gh builds up a relationship to the decrease of the capacity of resisting disturbance like the hyperpolarization stimulus as the resting state approaches the bifurcation point. The "typical"-resonance and non-resonance appear in the parameter region of the stable focus and node far away from the bifurcation points, respectively. The complex or "strange" dynamics, such as the "weak" resonance for the stable node near the transition point between the stable node and focus and the non-resonance for the stable focus close to the codimension-1 and -2 bifurcation points, are discussed. PMID- 29568264 TI - Lose-Shift Responding in Humans Is Promoted by Increased Cognitive Load. AB - The propensity of animals to shift choices immediately after unexpectedly poor reinforcement outcomes is a pervasive strategy across species and tasks. We report here on the memory supporting such lose-shift responding in humans, assessed using a binary choice task in which random responding is the optimal strategy. Participants exhibited little lose-shift responding when fully attending to the task, but this increased by 30%-40% in participants that performed with additional cognitive load that is known to tax executive systems. Lose-shift responding in the cognitively loaded adults persisted throughout the testing session, despite being a sub-optimal strategy, but was less likely as the time increased between reinforcement and the subsequent choice. Furthermore, children (5-9 years old) without load performed similarly to the cognitively loaded adults. This effect disappeared in older children aged 11-13 years old. These data provide evidence supporting our hypothesis that lose-shift responding is a default and reflexive strategy in the mammalian brain, likely mediated by a decaying memory trace, and is normally suppressed by executive systems. Reducing the efficacy of executive control by cognitive load (adults) or underdevelopment (children) increases its prevalence. It may therefore be an important component to consider when interpreting choice data, and may serve as an objective behavioral assay of executive function in humans that is easy to measure. PMID- 29568266 TI - Normalization of Blood Pressure With Spinal Cord Epidural Stimulation After Severe Spinal Cord Injury. AB - Chronic low blood pressure and orthostatic hypotension remain challenging clinical issues after severe spinal cord injury (SCI), affecting health, rehabilitation, and quality of life. We previously reported that targeted lumbosacral spinal cord epidural stimulation (scES) could promote stand and step functions and restore voluntary movement in patients with chronic motor complete SCI. This study addresses the effects of targeted scES for cardiovascular function (CV-scES) in individuals with severe SCI who suffer from chronic hypotension. We tested the hypothesis that CV-scES can increase resting blood pressure and attenuate chronic hypotension in individuals with chronic cervical SCI. Four research participants with chronic cervical SCI received an implant of a 16-electrode array on the dura (L1-S1 cord segments, T11-L1 vertebrae). Individual-specific CV-scES configurations (anode and cathode electrode selection, voltage, frequency, and pulse width) were identified to maintain systolic blood pressure within targeted normative ranges without skeletal muscle activity of the lower extremities as assessed by electromyography. These individuals completed five 2-h sessions using CV-scES in an upright, seated position during measurement of blood pressure and heart rate. Noninvasive continuous blood pressure was measured from a finger cuff by plethysmograph technique. For each research participant there were statistically significant increases in mean arterial pressure in response to CV-scES that was maintained within normative ranges. This result was reproducible over the five sessions with concomitant decreases or no changes in heart rate using individual-specific CV scES that was modulated with modest amplitude changes throughout the session. Our study shows that stimulating dorsal lumbosacral spinal cord can effectively and safely activate mechanisms to elevate blood pressures to normal ranges from a chronic hypotensive state in humans with severe SCI with individual-specific CV scES. PMID- 29568265 TI - Explicit Performance in Girls and Implicit Processing in Boys: A Simultaneous fNIRS-ERP Study on Second Language Syntactic Learning in Young Adolescents. AB - Learning a second language (L2) proceeds with individual approaches to proficiency in the language. Individual differences including sex, as well as working memory (WM) function appear to have strong effects on behavioral performance and cortical responses in L2 processing. Thus, by considering sex and WM capacity, we examined neural responses during L2 sentence processing as a function of L2 proficiency in young adolescents. In behavioral tests, girls significantly outperformed boys in L2 tests assessing proficiency and grammatical knowledge, and in a reading span test (RST) assessing WM capacity. Girls, but not boys, showed significant correlations between L2 tests and RST scores. Using functional near-infrared spectroscopy (fNIRS) and event-related potential (ERP) simultaneously, we measured cortical responses while participants listened to syntactically correct and incorrect sentences. ERP data revealed a grammaticality effect only in boys in the early time window (100-300 ms), implicated in phrase structure processing. In fNIRS data, while boys had significantly increased activation in the left prefrontal region implicated in syntactic processing, girls had increased activation in the posterior language-related region involved in phonology, semantics, and sentence processing with proficiency. Presumably, boys implicitly focused on rule-based syntactic processing, whereas girls made full use of linguistic knowledge and WM function. The present results provide important fundamental data for learning and teaching in L2 education. PMID- 29568267 TI - Performance of an Ambulatory Dry-EEG Device for Auditory Closed-Loop Stimulation of Sleep Slow Oscillations in the Home Environment. AB - Recent research has shown that auditory closed-loop stimulation can enhance sleep slow oscillations (SO) to improve N3 sleep quality and cognition. Previous studies have been conducted in lab environments. The present study aimed to validate and assess the performance of a novel ambulatory wireless dry-EEG device (WDD), for auditory closed-loop stimulation of SO during N3 sleep at home. The performance of the WDD to detect N3 sleep automatically and to send auditory closed-loop stimulation on SO were tested on 20 young healthy subjects who slept with both the WDD and a miniaturized polysomnography (part 1) in both stimulated and sham nights within a double blind, randomized and crossover design. The effects of auditory closed-loop stimulation on delta power increase were assessed after one and 10 nights of stimulation on an observational pilot study in the home environment including 90 middle-aged subjects (part 2).The first part, aimed at assessing the quality of the WDD as compared to a polysomnograph, showed that the sensitivity and specificity to automatically detect N3 sleep in real-time were 0.70 and 0.90, respectively. The stimulation accuracy of the SO ascending phase targeting was 45 +/- 52 degrees . The second part of the study, conducted in the home environment, showed that the stimulation protocol induced an increase of 43.9% of delta power in the 4 s window following the first stimulation (including evoked potentials and SO entrainment effect). The increase of SO response to auditory stimulation remained at the same level after 10 consecutive nights. The WDD shows good performances to automatically detect in real-time N3 sleep and to send auditory closed-loop stimulation on SO accurately. These stimulation increased the SO amplitude during N3 sleep without any adaptation effect after 10 consecutive nights. This tool provides new perspectives to figure out novel sleep EEG biomarkers in longitudinal studies and can be interesting to conduct broad studies on the effects of auditory stimulation during sleep. PMID- 29568268 TI - Synergistic Effect on Neurodegeneration by N-Truncated Abeta4-42 and Pyroglutamate Abeta3-42 in a Mouse Model of Alzheimer's Disease. AB - The N-terminally truncated pyroglutamate Abeta3-42 (AbetapE3-42) and Abeta4-42 peptides are known to be highly abundant in the brain of Alzheimer's disease (AD) patients. Both peptides show enhanced aggregation and neurotoxicity in comparison to full-length Abeta, suggesting that these amyloid peptides may play an important role in the pathogenesis of AD. The aim of the present work was to study the direct effect of the combination of AbetapE3-42 and Abeta4-42 on ongoing AD-related neuron loss, pathology, and neurological deficits in transgenic mice. Bigenic mice were generated by crossing the established TBA42 and Tg4-42 mouse models expressing the N-truncated Abeta peptides AbetapE3-42 and Abeta4-42, respectively. After generation of the bigenic mice, detailed phenotypical characterization was performed using either immunostainings to evaluate amyloid pathology or quantification of neuron numbers using design-based stereology. The elevated plus maze was used to study anxiety levels. In order to evaluate sensori-motor deficits, the inverted grid, the balance beam and the string suspension tasks were applied. We could demonstrate that co-expression of AbetapE3-42 and Abeta4-42 accelerates neuron loss in the CA1 pyramidal layer of young bigenic mice as seen by reduced neuron numbers in comparison to single transgenic homozygous mice expressing either AbetapE3-42 or Abeta4-42. This observation coincides with the robust intraneuronal Abeta accumulation observed in the bigenic mice. In addition, loss of anxiety and motor deficits were enhanced in an age-dependent manner. The sensori-motor deficits correlate with the abundant spinal cord pathology, as demonstrated by robust intracellular Abeta accumulation within motor neurons and extracellular Abeta deposition. Our observations demonstrate that a combination of AbetapE3-42 and Abeta4-42 has a stronger effect on ongoing AD pathology than the peptides alone. Therefore, AbetapE3-42 and Abeta4-42 might represent excellent potential therapeutic targets and diagnostic markers for AD.

AB - Background: As the signal transduction of 5-HT4 receptors on cholinergic neurons innervating smooth muscle is controlled by phosphodiesterase (PDE) 4 in porcine stomach and colon, and human large intestine, the in vivo gastroprokinetic effects of a 5-HT4 receptor agonist might be enhanced by combination with a selective PDE4 inhibitor. The presence of 5-HT4 receptors on cholinergic neurons towards murine gastrointestinal circular muscle was recently shown. If the control of this receptor pathway by PDE4 is also present in mice, this might be a good model for in vivo testing of the combination therapy. Therefore this study investigates the role of cAMP catalyzing PDEs in smooth muscle cell activity and in the intraneuronal signal transduction of the 5-HT4 receptors in the gastrointestinal tract of C57Bl/6J mice. Methods: In circular smooth muscle strips from murine fundus, jejunum, and colon, submaximal cholinergic contractions were induced by either electrical field stimulation (EFS) or by carbachol (muscarinic receptor agonist). The influence of the PDE inhibitors IBMX (non-selective), vinpocetine (PDE1), EHNA (PDE2), cilostamide (PDE3), and rolipram (PDE4) was tested on these contractions and on the facilitating effect of a submaximal concentration of prucalopride (5-HT4 receptor agonist) on EFS induced contractions. Results: In the three gastrointestinal regions, IBMX and cilostamide concentration-dependently decreased carbachol- as well as EFS-induced contractions. Some inhibitory effect was also observed with rolipram. In the fundus a non-significant trend for an enhancement of the facilitating effect of prucalopride on EFS-induced contractions was observed with IBMX, but none of the selective PDE inhibitors enhanced the facilitating effect of prucalopride in fundus, jejunum or colon. Conclusion: In analogy with the porcine gastrointestinal tract, in murine fundus, jejunum, and colon circular smooth muscle PDE3 is the main regulator of the cAMP turnover, with some contribution of PDE4. In contrast to the porcine gastrointestinal tract, the in vitro facilitation of electrically induced cholinergic contractions by 5-HT4 receptor stimulation could not be enhanced by specific PDE inhibition. The C57Bl/6J murine model is thus not suitable for in vivo testing of a 5-HT4 receptor agonist combined with a selective PDE4 inhibitor. PMID- 29568271 TI - End-of-Fiber Signals Strongly Influence the First and Second Phases of the M Wave in the Vastus Lateralis: Implications for the Study of Muscle Excitability. AB - It has been recurrently observed that, for compound muscle action potentials (M wave) recorded over the innervation zone of the vastus lateralis, the descending portion of the first phase generally shows an "inflection" or "shoulder." We sought to clarify the electrical origin of this shoulder-like feature and examine its implications. M waves evoked by maximal single shocks to the femoral nerve were recorded in monopolar and bipolar configurations from 126 individuals using classical (10-mm recording diameter, 20-mm inter-electrode distance) electrodes and from eight individuals using small electrodes arranged in a linear array. The changes of the M-wave waveform at different positions along the muscle fibers' direction were examined. The shoulder was identified more frequently in monopolar (97%) than in bipolar (46%) M waves. The shoulder of M waves recorded at different distances from the innervation zone had the same latency. Furthermore, the shoulder of the M wave recorded over the innervation zone coincided in latency with the positive peak of that recorded beyond the muscle. The positive phase of the M wave detected 20 mm away from the innervation zone was essentially composed of non-propagating components. The shoulder-like feature in monopolar and bipolar M waves results from the termination of action potentials at the superficial aponeurosis of the vastus lateralis. We conclude that, only the amplitude of the first phase, and not the second, of M waves recorded monopolarly and/or bipolarly in close proximity to the innervation zone can be used reliably to monitor possible changes in muscle membrane excitability. PMID- 29568272 TI - Four TRPM4 Cation Channel Mutations Found in Cardiac Conduction Diseases Lead to Altered Protein Stability. AB - Transient receptor potential melastatin member 4 (TRPM4), a non-selective cation channel, mediates cell membrane depolarization in immune response, insulin secretion, neurological disorders, and cancer. Pathological variants in TRPM4 gene have been linked to several cardiac phenotypes such as complete heart block (CHB), ventricular tachycardia, and Brugada syndrome (BrS). Despite recent findings regarding the functional implications of TRPM4 in cardiac diseases, the molecular and cellular mechanisms leading to altered conduction are poorly understood. In the present study, we identify and characterize four novel TRPM4 variants found in patients with CHB or ventricular fibrillation. Three of them, p.A101T, p.S1044C and a double variant p.A101T/P1204L, led to a decreased expression and function of the channel. On the contrary, the variant p.Q854R showed an increase in TRPM4 current. Recent evidence indicates that altered degradation rate of mutant proteins represents a pathogenic mechanism underlying genetic diseases. In consequence, protein turnover of WT-TRPM4 and TRPM4 variants overexpressed in HEK293 cells was analyzed using cycloheximide, an inhibitor of protein biosynthesis. Upon addition of cycloheximide, WT-TRPM4 decayed with a half-life of ~20 h, while loss-of-expression variants showed a ~30% increase in degradation rate, with a half-life close to 12 h. Together, the gain-of expression variant showed a higher stability and a doubled half-life compared to WT-TRPM4. In conclusion, decreased or increased protein expression of several TRPM4 variants linked to cardiac conduction disorders or ventricular arrhythmias were found to be caused by altered TRPM4 half-life compared to the WT form. PMID- 29568270 TI - Unifying Theories of Psychedelic Drug Effects. AB - How do psychedelic drugs produce their characteristic range of acute effects in perception, emotion, cognition, and sense of self? How do these effects relate to the clinical efficacy of psychedelic-assisted therapies? Efforts to understand psychedelic phenomena date back more than a century in Western science. In this article I review theories of psychedelic drug effects and highlight key concepts which have endured over the last 125 years of psychedelic science. First, I describe the subjective phenomenology of acute psychedelic effects using the best available data. Next, I review late 19th-century and early 20th-century theories model psychoses theory, filtration theory, and psychoanalytic theory-and highlight their shared features. I then briefly review recent findings on the neuropharmacology and neurophysiology of psychedelic drugs in humans. Finally, I describe recent theories of psychedelic drug effects which leverage 21st-century cognitive neuroscience frameworks-entropic brain theory, integrated information theory, and predictive processing-and point out key shared features that link back to earlier theories. I identify an abstract principle which cuts across many theories past and present: psychedelic drugs perturb universal brain processes that normally serve to constrain neural systems central to perception, emotion, cognition, and sense of self. I conclude that making an explicit effort to investigate the principles and mechanisms of psychedelic drug effects is a uniquely powerful way to iteratively develop and test unifying theories of brain function. PMID- 29568273 TI - Regular Aerobic, Resistance, and Cross-Training Exercise Prevents Reduced Vascular Function Following a High Sugar or High Fat Mixed Meal in Young Healthy Adults. AB - The postprandial state can negatively influence flow mediated dilation (FMD), a predictor of atherosclerosis and cardiovascular disease. This investigation was designed to determine the effect of regular aerobic and/or resistance exercise on postprandial FMD after a high sugar or high fat mixed meal. Forty-five healthy participants were recruited from one of four groups: lean sedentary (SED), runners, weight lifters, and cross-trainers. Participants were randomly crossed over to a high sugar meal (HSM) and a high fat mixed meal (HFMM; both fat and carbohydrate). Pre-and postprandial endothelial function was assessed for both meals using brachial artery FMD. Plasma lipids, insulin, glucose, hs-CRP, and SOD were also measured with both meals. Endothelium-independent dilation was determined via sublingual nitroglycerin. Brachial artery FMD was reduced in SED following the HSM (9.9 +/- 0.9% at baseline, peak reduction at 60 min 6.5 +/- 1.0%) and the HFMM (9.4 +/- 0.9% at baseline, peak reduction at 120 min 5.9 +/- 1.2%; P < 0.05 for both, Mean +/- SEM). There was no change in FMD after either HSM or HFMM in runners, weight lifters, and cross-trainers. Post-prandial increases in blood glucose, insulin and triglycerides were less pronounced in the exercisers compared to SED. In addition, exercisers presented lower baseline plasma hs-CRP and higher SOD activity. Nitroglycerin responses were similar among groups. These results suggest that endothelial function is reduced in sedentary adults after a HSM or HFMM, but not in regular aerobic or resistance exercisers. This response may be due to favorable postprandial metabolic responses or lower postprandial levels of inflammation and oxidative stress. These findings may help to explain the cardioprotective effect of exercise. PMID- 29568274 TI - Transplantation of Normal Adipose Tissue Improves Blood Flow and Reduces Inflammation in High Fat Fed Mice With Hindlimb Ischemia. AB - Background: Fat deposition is associated with peripheral arterial disease. Adipose tissue has recently been implicated in vascular remodeling and angiogenic activity. We hypothesized that the transplantation of adipose tissues from normal mice improves blood flow perfusion and neovascularization in high-fat diet fed mice. Methods: After 14 weeks of high-fat diet (HFD)-fed mice, unilateral hind limb ischemia was performed. Subcutaneous white adipose tissue (WAT) and brown adipose tissue (BAT) fat pads were harvested from normal EGFP mice, and subcutaneously transplanted over the region of the adductor muscles of HFD mice. Blood flow was measured using Laser Doppler Scanner. Vascular density, macrophages infiltration, and macrophage polarization were examined by RT-qPCR, and immunohistochemistry. Results: We found that the transplantation of WAT derived from normal mice improved functional blood flow in HFD-fed mice compared to mice transplanted with BAT and sham-treated mice. WAT transplantation increased the recruitment of pericytes associated with nascent blood vessels, but did not affect capillary formation. Furthermore, transplantation of WAT ameliorated HFD-induced insulin resistance, M2 macrophage predominance and the release of arteriogenic factors in ischemic muscles. Mice receiving WAT also displayed a marked reduction in several proinflammatory cytokines. In contrast, mice transplanted with BAT were glucose intolerant and demonstrated increased IL 6 levels in ischemic muscles. Conclusion: These results indicate that transplantation of adipose tissue elicits improvements in blood perfusion and beneficial effects on systemic glucose homeostasis and could be a promising therapeutic option for the treatment of diabetic peripheral arterial disease. PMID- 29568276 TI - Effects of Continuing Oral Risperidone vs. Switching from Risperidone to Risperidone Long-Acting Injection on Cognitive Function in Stable Schizophrenia Patients: A Pilot Study. AB - Objectives: Risperidone is the first new generation antipsychotic drug to become available as a long-acting injection (LAI). The purpose of this study was to evaluate the effects of switching from oral risperidone to risperidone LAI (RLAI) on cognitive function in stable schizophrenia patients compared with the effects of continuing oral risperidone. Methods: Sixteen stable patients who had received risperidone monotherapy for at least 3 months were enrolled (the RLAI group). Before and 24 weeks after switching to RLAI, the Japanese-language version of the Brief Assessment of Cognition in Schizophrenia (BACS-J) and the Positive and Negative Syndrome Scale (PANSS) were administered. To exclude the possibility of learning effects on the BACS-J results, 14 patients with stable schizophrenia who continued oral risperidone treatment were also assessed (the RIS group). Results: The two groups did not differ with respect to changes in the PANSS score, and no emergent side effects, including extrapyramidal symptoms, were observed. The BACS J score for verbal memory exhibited greater improvement in the RLAI group than in the RIS group (p = 0.047). Conclusion: The results of this preliminary study suggest that switching from oral risperidone to RLAI may improve verbal capability more than continuing with oral risperidone. However, these findings must be replicated in a larger, double-blind study. PMID- 29568275 TI - Neurosteroids in Schizophrenia: Pathogenic and Therapeutic Implications. AB - Neurosteroids are a group of important endogenous molecules affecting many neural functions in the brain. Increasing evidence suggests a possible role of these neurosteroids in the pathology and symptomatology of schizophrenia (SZ) and other mental disorders. The aim of this review is to summarize the current knowledge about the neural functions of neurosteroids in the brain, and to evaluate the role of the key neurosteroids as candidate modulators in the etiology and therapeutics of SZ. The present paper provides a brief introduction of neurosteroid metabolism and distribution, followed by a discussion of the mechanisms underlying neurosteroid actions in the brain. The content regarding the modulation of the GABAA receptor is elaborated, given the considerable knowledge of its interactions with other neurotransmitter and neuroprotective systems, as well as its ameliorating effects on stress that may play a role in the SZ pathophysiology. In addition, several preclinical and clinical studies suggested a therapeutic benefit of neurosteroids in SZ patients, even though the presence of altered neurosteroid pathways in the circulating blood and/or brain remains debatable. Following treatment of antipsychotic drugs in SZ, therapeutic benefits have also been linked to the regulation of neurosteroid signaling. Specifically, the neurosteroids such as pregnenolone and dehydroepiandrosterone affect a broad spectrum of behavioral functions through their unique molecular characteristics and may represent innovative therapeutic targets for SZ. Future investigations in larger cohorts with long-term follow-ups will be required to ascertain the neuropsychopharmacological role of this yet unexploited class of neurosteroid agents. PMID- 29568277 TI - The Development and Validation of the Bergen-Yale Sex Addiction Scale With a Large National Sample. AB - The view that problematic excessive sexual behavior ("sex addiction") is a form of behavioral addiction has gained more credence in recent years, but there is still considerable controversy regarding operationalization of the concept. Furthermore, most previous studies have relied on small clinical samples. The present study presents a new method for assessing sex addiction-the Bergen-Yale Sex Addiction Scale (BYSAS)-based on established addiction components (i.e., salience/craving, mood modification, tolerance, withdrawal, conflict/problems, and relapse/loss of control). Using a cross-sectional survey, the BYSAS was administered to a broad national sample of 23,533 Norwegian adults [aged 16-88 years; mean (+/- SD) age = 35.8 +/- 13.3 years], together with validated measures of the Big Five personality traits, narcissism, self-esteem, and a measure of sexual addictive behavior. Both an exploratory and a confirmatory factor analysis (RMSEA = 0.046, CFI = 0.998, TLI = 0.996) supported a one-factor solution, although a local dependence between two items (Items 1 and 2) was detected. Furthermore, the scale had good internal consistency (Cronbach's alpha = 0.83). The BYSAS correlated significantly with the reference scale (r = 0.52), and demonstrated similar patterns of convergent and discriminant validity. The BYSAS was positively related to extroversion, neuroticism, intellect/imagination, and narcissism, and negatively related to conscientiousness, agreeableness, and self esteem. High scores on the BYSAS were more prevalent among those who were men, single, of younger age, and with higher education. The BYSAS is a brief, and psychometrically reliable and valid measure for assessing sex addiction. However, further validation of the BYSAS is needed in other countries and contexts. PMID- 29568278 TI - Depression, Hopelessness, and Complicated Grief in Survivors of Suicide. AB - Suicide often has a severe impact on the surviving family and friends. There is a need to better understand the psychological and psychopathological consequences of losing a significant other by suicide. The aim of the present study was to assess hopelessness, depression, suicide risk, complicated grief, intrusive memories, and avoidance in a sample of suicide survivors. In this observational study, 35 bereaved individuals were recruited at the Suicide Prevention Centre of Sant'Andrea Hospital in Rome. Individuals were administered a series of validated instruments: the Beck Depression Inventory II (BDI), the Beck Hopelessness Scale (BHS), the Inventory of Complicated Grief (ICG), the Impact of Event Scale (IES), the Subjective Happiness Scale (SHS), and the Satisfaction With Life Scale (SWLS). Most survivors (62.8%) obtained high scores on measures of complicated grief. Scores on the measure of complicated grief were associated with intrusiveness of thoughts and memories, attempts to prevent the thoughts and emotions related to the event, depressive symptoms and hopelessness, and lower scores for feelings of happiness and satisfaction with life. A subgroup of suicide survivors may be at risk of severe psychological distress and suicidal behavior. Identification of these survivors is a necessary step for providing appropriate counseling and psychotherapy. PMID- 29568279 TI - Aging and the Change in Fatigue and Sleep - A Longitudinal Study Across 8 Years in Three Age Groups. AB - Fatigue is prevalent in the population and usually linked to sleep problems, and both are related to age. However, previous studies have been cross-sectional. The purpose of the present study was to investigate the trajectories of sleep and fatigue across 8 years of aging in a large group (N > 8.000) of individuals. A second purpose was to investigate whether fatigue trajectories would differ between age groups, and whether different trajectories of fatigue would be reflected in a corresponding difference in trajectories for sleep variables. Results from mixed model analyses showed that fatigue decreased across 8 years in all age groups, while sleep problems increased, non-restorative sleep decreased, weekend sleep duration decreased, and weekday sleep duration showed different patterns depending on age. Furthermore, the larger the decrease in fatigue, the larger was the increase in sleep duration across years, the lower was the increase of sleep problems, and the larger was the decrease of non-restorative sleep. The results suggest that aging has positive effects on fatigue and sleep and that these changes are linked. PMID- 29568280 TI - Preliminary Checklist for Reporting Observational Studies in Sports Areas: Content Validity. AB - Observational studies are based on systematic observation, understood as an organized recording and quantification of behavior in its natural context. Applied to the specific area of sports, observational studies present advantages when comparing studies based on other designs, such as the flexibility for adapting to different contexts and the possibility of using non-standardized instruments as well as a high degree of development in specific software and data analysis. Although the importance and usefulness of sports-related observational studies have been widely shown, there is no checklist to report these studies. Consequently, authors do not have a guide to follow in order to include all of the important elements in an observational study in sports areas, and reviewers do not have a reference tool for assessing this type of work. To resolve these issues, this article aims to develop a checklist to measure the quality of sports related observational studies based on a content validity study. The participants were 22 judges with at least 3 years of experience in observational studies, sports areas, and methodology. They evaluated a list of 60 items systematically selected and classified into 12 dimensions. They were asked to score four aspects of each item on 5-point Likert scales to measure the following dimensions: representativeness, relevance, utility, and feasibility. The judges also had an open-format section for comments. The Osterlind index was calculated for each item and for each of the four aspects. Items were considered appropriate when obtaining a score of at least 0.5 in the four assessed aspects. After considering these inclusion criteria and all of the open-format comments, the resultant checklist consisted of 54 items grouped into the same initial 12 dimensions. Finally, we highlight the strengths of this work. We also present its main limitation: the need to apply the resultant checklist to obtain data and, thus, increase quality indicators of its psychometric properties. For this reason, as relevant actions for further development, we encourage expert readers to use it and provide feedback; we plan to apply it to different sport areas. PMID- 29568281 TI - Quantitative Analysis of Bradykinesia and Rigidity in Parkinson's Disease. AB - Background: In the last decades, several studies showed that wearable sensors, used for assessing Parkinson's disease (PD) motor symptoms and recording their fluctuations, could provide a quantitative and reliable tool for patient's motor performance monitoring. Objective: The aim of this study is to make a step forward the capability of quantitatively describing PD motor symptoms. The specific aims are: identify the most sensible place where to locate sensors to monitor PD bradykinesia and rigidity, and identify objective indexes able to discriminate PD OFF/ON motor status, and PD patients from healthy subjects (HSs). Methods: Fourteen PD patients (H&Y stage 1-2.5), and 13 age-matched HSs, were enrolled. Five magneto-inertial wearable sensors, placed on index finger, thumb, metacarpus, wrist, and arm, were used as motion tracking systems. Sensors were placed on the most affected arm of PD patients, and on dominant hand of HS. Three UPDRS part III tasks were evaluated: rigidity (task 22), finger tapping (task 23), and prono-supination movements of the hands (task 25). A movement disorders expert rated the three tasks according to the UPDRS part III scoring system. In order to describe each task, different kinematic indexes from sensors were extracted and analyzed. Results: Four kinematic indexes were extracted: fatigability; total time; total power; smoothness. The last three well-described PD OFF/ON motor status, during finger-tapping task, with an index finger sensor. During prono-supination task, wrist sensor was able to differentiate PD OFF/ON motor condition. Smoothness index, used as a rigidity descriptor, provided a good discrimination of the PD OFF/ON motor status. Total power index, showed the best accuracy for PD vs healthy discrimination, with any sensor location among index finger, thumb, metacarpus, and wrist. Conclusion: The present study shows that, in order to better describe the kinematic features of Parkinsonian movements, wearable sensors should be placed on a distal location on upper limb, on index finger or wrist. The proposed indexes demonstrated a good correlation with clinical scores, thus providing a quantitative tool for research purposes in future studies in this field. PMID- 29568282 TI - Dose-Dependent Effect of Intravenous Administration of Human Umbilical Cord Derived Mesenchymal Stem Cells in Neonatal Stroke Mice. AB - Neonatal brain injury induced by stroke causes significant disability, including cerebral palsy, and there is no effective therapy for stroke. Recently, mesenchymal stem cells (MSCs) have emerged as a promising tool for stem cell based therapies. In this study, we examined the safety and efficacy of intravenously administered human umbilical cord-derived MSCs (UC-MSCs) in neonatal stroke mice. Pups underwent permanent middle cerebral artery occlusion at postnatal day 12 (P12), and low-dose (1 * 104) or high-dose (1 * 105) UC-MSCs were administered intravenously 48 h after the insult (P14). To evaluate the effect of the UC-MSC treatment, neurological behavior and cerebral blood flow were measured, and neuroanatomical analysis was performed at P28. To investigate the mechanisms of intravenously injected UC-MSCs, systemic blood flowmetry, in vivo imaging and human brain-derived neurotrophic factor (BDNF) measurements were performed. Functional disability was significantly improved in the high-dose UC MSC group when compared with the vehicle group, but cerebral blood flow and cerebral hemispheric volume were not restored by UC-MSC therapy. The level of exogenous human BDNF was elevated only in the cerebrospinal fluid of one pup 24 h after UC-MSC injection, and in vivo imaging revealed that most UC-MSCs were trapped in the lungs and disappeared in a week without migration toward the brain or other organs. We found that systemic blood flow was stable over the 10 min after cell administration and that there were no differences in mortality among the groups. Immunohistopathological assessment showed that the percent area of Iba1-positive staining in the peri-infarct cortex was significantly reduced with the high-dose UC-MSC treatment compared with the vehicle treatment. These results suggest that intravenous administration of UC-MSCs is safe for a mouse model of neonatal stroke and improves dysfunction after middle cerebral artery occlusion by modulating the microglial reaction in the peri-infarct cortex. PMID- 29568283 TI - Comparative Genomics of the Baltic Sea Toxic Cyanobacteria Nodularia spumigena UHCC 0039 and Its Response to Varying Salinity. AB - Salinity is an important abiotic factor controlling the distribution and abundance of Nodularia spumigena, the dominating diazotrophic and toxic phototroph, in the brackish water cyanobacterial blooms of the Baltic Sea. To expand the available genomic information for brackish water cyanobacteria, we sequenced the isolate Nodularia spumigena UHCC 0039 using an Illumina-SMRT hybrid sequencing approach, revealing a chromosome of 5,294,286 base pairs (bp) and a single plasmid of 92,326 bp. Comparative genomics in Nostocales showed pronounced genetic similarity among Nodularia spumigena strains evidencing their short evolutionary history. The studied Baltic Sea strains share similar sets of CRISPR Cas cassettes and a higher number of insertion sequence (IS) elements compared to Nodularia spumigena CENA596 isolated from a shrimp production pond in Brazil. Nodularia spumigena UHCC 0039 proliferated similarly at three tested salinities, whereas the lack of salt inhibited its growth and triggered transcriptome remodeling, including the up-regulation of five sigma factors and the down regulation of two other sigma factors, one of which is specific for strain UHCC 0039. Down-regulated genes additionally included a large genetic region for the synthesis of two yet unidentified natural products. Our results indicate a remarkable plasticity of the Nodularia salinity acclimation, and thus salinity strongly impacts the intensity and distribution of cyanobacterial blooms in the Baltic Sea. PMID- 29568284 TI - Geobacter Dominates the Inner Layers of a Stratified Biofilm on a Fluidized Anode During Brewery Wastewater Treatment. AB - In this study, we designed a microbial electrochemical fluidized bed reactor (ME FBR), with an electroconductive anodic bed made of activated carbon particles for treating a brewery wastewater. Under a batch operating mode, acetate and propionate consumption rates were 13-fold and 2.4-fold higher, respectively, when the fluidized anode was polarized (0.2 V) with respect to open circuit conditions. Operating in a continuous mode, this system could effectively treat the brewery effluent at organic loading rates (OLR) over 1.7 kg m-3NRV d-1 and with removal efficiencies of 95 +/- 1.4% (hydraulic retention time of 1 day and an influent of 1.7 g-COD L-1). The coulombic efficiency values highly depended upon the OLR applied, and varied from a 56 +/- 15% to 10 +/- 1%. Fluorescence in situ hybridization (FISH) analysis revealed a relative high abundance of Geobacter species (ca. 20%), and clearly showed a natural microbial stratification. Interestingly, the Geobacter cluster was highly enriched in the innermost layers of the biofilm (thickness of 10 MUm), which were in contact with the electroconductive particles of bed, whereas the rest of bacteria were located in the outermost layers. To our knowledge, this is the first time that such a clear microbial stratification has been observed on an anode-respiring biofilm. Our results revealed the relevant role of Geobacter in switching between the electrode and other microbial communities performing metabolic reactions in the outermost environment of the biofilm. PMID- 29568285 TI - Leishmania donovani Activates Hypoxia Inducible Factor-1alpha and miR-210 for Survival in Macrophages by Downregulation of NF-kappaB Mediated Pro-inflammatory Immune Response. AB - Micro RNAs (miRNAs) have emerged as a critical regulator of several biological processes in both animals and plants. They have also been associated with regulation of immune responses in many human diseases during recent years. Visceral leishmaniasis (VL) is the most severe form of leishmaniasis, which is characterized by impairment of both innate and adaptive immune responses. In the present study, we observed that Leishmania establishes hypoxic environment in host macrophages that induces the expression of hypoxia inducible factor-1alpha (HIF-1alpha) and miRNA-210. Further, the expression of miRNA-210 was found to be dependent on activation of HIF-1alpha expression. The HIF-1alpha silencing by siRNA resulted in significantly (p < 0.001) decreased expression of miR-210 in parasites infected macrophages. We also observed that in siHIF-1alpha or antagomir-210 treated L. donovani infected macrophages, the parasitic load and percentage infectivity were significantly (p < 0.001) decreased. Furthermore, we found that inhibition of miR-210 leads to activation of NF-kappaB subunit p50, and it forms heterodimer with p65 and translocates into the nucleus from the cytoplasm. This significantly (p < 0.05) induced the transcription of pro inflammatory cytokines genes such as TNF-alpha and IL-12 in miRNA-210 inhibited macrophages compared to uninhibited macrophages whereas the level of IL-10, an anti-inflammatory cytokine, was found to be significantly decreased (p < 0.001). These findings suggested that L. donovani infection induces hypoxic environment inside the macrophages that activates HIF-1alpha. Further, HIF-1alpha upregulates miR-210, which eventually establishes a suitable environment for the survival of parasite inside the host macrophages by downregulating NF-kappaB mediated pro inflammatory immune responses. PMID- 29568287 TI - The Human Polyomavirus Middle and Alternative T-Antigens; Thoughts on Roles and Relevance to Cancer. AB - Approximately 15-20% of human cancer is related to infection, which renders them potentially preventable by antimicrobial or antiviral therapy. Human polyomaviruses (PyVs) are relevant in this regard, as illustrated by the involvement of Merkel cell polyomavirus (MCPyV) in the development of Merkel cell carcinoma. The polyomavirus Small and Large tumor antigen (ST and LT) have been extensively studied with respect to their role in oncogenesis. Recently it was shown that a number of human PyVs, including MCPyV and the trichodysplasia spinulosa polyomavirus (TSPyV), express additional T-antigens called Middle T (MT) and alternative T (ALT). ALT is encoded by ORF5, also known as the alternative T open reading frame (ALTO), which also encodes the second exon of MT, and overlaps out-of-frame with the second exon of LT. Previously, MT was considered unique for oncogenic rodent polyomaviruses, and ALT was still unknown. In this mini-review, we want to point out there are important reasons to explore the involvement of MT and ALT in human cellular transformation. First, just like their rodent equivalents, MT and ALT probably disrupt cellular pathways that control signaling and proliferation. Second, expression of the MT and ALT encoding ORF5/ALTO characterizes a monophyletic polyomavirus clade that includes human and animal PyVs with known oncogenic potential. And third, ORF5/ALTO is subject to strong positive selection aimed specifically at a short linear motif within MT and ALT that overlaps completely with the RB-binding motif in LT. The latter suggests tight interplay between these T-antigens with possible consequences for cell transformation.

AB - Infections with cutaneous papillomaviruses have been linked to cutaneous squamous cell carcinomas that arise in patients who suffer from a rare genetic disorder, epidermodysplasia verruciformis, or those who have experienced long-term, systemic immunosuppression following organ transplantation. The E6 proteins of the prototypical cutaneous human papillomavirus (HPV) 5 and HPV8 inhibit TGF-beta and NOTCH signaling. The Mus musculus papillomavirus 1, MmuPV1, infects laboratory mouse strains and causes cutaneous skin warts that can progress to squamous cell carcinomas. MmuPV1 E6 shares biological and biochemical activities with HPV8 E6 including the ability to inhibit TGF-beta and NOTCH signaling by binding the SMAD2/SMAD3 and MAML1 transcription factors, respectively. Inhibition of TGF-beta and NOTCH signaling is linked to delayed differentiation and sustained proliferation of differentiating keratinocytes. Furthermore, the ability of MmuPV1 E6 to bind MAML1 is necessary for wart and cancer formation in experimentally infected mice. Hence, experimental MmuPV1 infection in mice will be a robust and valuable experimental system to dissect key aspects of cutaneous HPV infection, pathogenesis, and carcinogenesis.

AB - Since 1999 Vaccinia virus (VACV) outbreaks involving bovines and humans have been reported in Brazil; this zoonosis is known as Bovine Vaccinia (BV) and is mainly an occupational disease of milkers. It was only in 2008 (and then again in 2011 and 2014) however, that VACV was found causing natural infections in Brazilian equids. These reports involved only equids, no infected humans or bovines were identified, and the sources of infections remain unknown up to date. The peculiarities of Equine Vaccinia outbreaks (e.g., absence of human infection), the frequently shared environments, and fomites by equids and bovines in Brazilian farms and the remaining gaps in BV epidemiology incited a question over OPV serological status of equids in Brazil. For this report, sera from 621 equids - representing different species, ages, sexes and locations of origin within Minas Gerais State, southeast Brazil - were examined for the presence of anti Orthopoxvirus (OPV) antibodies. Only 74 of these were sampled during an Equine Vaccinia outbreak, meaning some of these specific animals presented typical lesions of OPV infections. The majority of sera, however, were sampled from animals without typical signs of OPV infection and during the absence of reported Bovine or Equine Vaccinia outbreaks. Results suggest the circulation of VACV among equids of southeast Brazil even prior to the time of the first VACV outbreak in 2008. There is a correlation of OPVs outbreaks among bovines and equids although many gaps remain to our understanding of its nature. The data obtained may even be carefully associated to recent discussion over OPVs history. Moreover, data is available to improve the knowledge and instigate new researches regarding OPVs circulation in Brazil and worldwide. PMID- 29568289 TI - An Ontology Systems Approach on Human Brain Expression and Metaproteomics. AB - Research in the last decade has shown growing evidence of the gut microbiota influence on brain physiology. While many mechanisms of this influence have been proposed in animal models, most studies in humans are the result of a pathology dysbiosis association and very few have related the presence of certain taxa with brain substructures or molecular pathways. In this paper, we associated the functional ontologies in the differential expression of brain substructures from the Allen Brain Atlas database, with those of the metaproteome from the Human Microbiome Project. Our results showed several coherent clustered ontologies where many taxa could influence brain expression and physiology. A detailed analysis of psychobiotics showed specific slim ontologies functionally associated with substructures in the basal ganglia and cerebellar cortex. Some of the most relevant slim ontology groups are related to Ion transport, Membrane potential, Synapse, DNA and RNA metabolism, and Antigen processing, while the most relevant neuropathology found was Parkinson disease. In some of these cases, new hypothetical gut microbiota-brain interaction pathways are proposed. PMID- 29568290 TI - Anti-adhesion Property of the Potential Probiotic Strain Lactobacillus fermentum 8711 Against Methicillin-Resistant Staphylococcus aureus (MRSA). AB - Methicillin-resistant Staphylococcus aureus (MRSA) is a multidrug-resistant pathogen and one of the leading causes of nosocomial infection worldwide. Probiotic bacteria play a significant role in preventive or therapeutic interventions of gastrointestinal infections in human as well as animals. In this study, we have investigated the adhesion property of the probiotic strain Lactobacillus fermentum MTCC 8711 and its ability to prevent the adhesion of MRSA to human colon adenocarcinoma cells, Caco-2. We have shown that L. fermentum could efficiently adhere to the Caco-2 cells. Also, we have shown that L. fermentum significantly reduced MRSA adhesion to Caco-2 cells. Three types of experiments were performed to assess the anti-adhesion property of L. fermentum against MRSA. Inhibition (Caco-2 cells were pre-treated with L. fermentum, and subsequently MRSA was added), competition (both L. fermentum and MRSA were added to Caco-2 cells simultaneously), and displacement or exclusion (Caco-2 cells were pre-treated with MRSA, and subsequently L. fermentum was added). In all three experiments, adhesion of MRSA was significantly reduced. Interestingly, L. fermentum could efficiently displace the adhered MRSA, and hence this probiotic can be used for therapeutic applications also. In cytotoxicity assay, we found that L. fermentum per se was not cytotoxic, and also significantly reduced the MRSA-induced cytotoxicity. The protective effect occurred without affecting Caco 2 cell morphology and viability. PMID- 29568291 TI - Macroalgae Extracts From Antarctica Have Antimicrobial and Anticancer Potential. AB - Background: Macroalgae are sources of bioactive compounds due to the large number of secondary metabolites they synthesize. The Antarctica region is characterized by extreme weather conditions and abundant aggregations of macroalgae. However, current knowledge on their biodiversity and their potential for bio-prospecting is still fledging. This study evaluates the antimicrobial and cytotoxic activity of different extracts of four macroalgae (Cystosphaera jacquinotii, Iridaea cordata, Himantothallus grandifolius, and Pyropia endiviifolia) from the Antarctic region against cancer and non-cancer cell lines. Methods: The antimicrobial activity of macroalgae was evaluated by the broth microdilution method. Extracts were assessed against Staphylococcus aureus ATCC 19095, Enterococcus faecalis ATCC 4083, Escherichia coli ATCC29214, Pseudomonas aeruginosa ATCC 9027, Candida albicans ATCC 62342, and the clinical isolates from the human oral cavity, namely, C. albicans (3), C. parapsilosis, C. glabrata, C. lipolytica, and C. famata. Cytotoxicity against human epidermoid carcinoma (A 431) and mouse embryonic fibroblast (NIH/3T3) cell lines was evaluated with MTT colorimetric assay. Results: An ethyl acetate extract of H. grandifolius showed noticeable antifungal activity against all fungal strains tested, including fluconazole-resistant samples. Cytotoxicity investigation with a cancer cell line revealed that the ethyl acetate extract of I. cordata was highly cytotoxic against A-431 cancer cell line, increasing the inhibitory ratio to 91.1 and 95.6% after 24 and 48 h exposure, respectively, for a concentration of 500 MUg mL-1. Most of the algal extracts tested showed little or no cytotoxicity against fibroblasts. Conclusion: Data suggest that macroalgae extracts from Antarctica may represent a source of therapeutic agents. HIGHLIGHTS Different macroalgae samples from Antarctica were collected and the lyophilized biomass of each macroalgae was extracted sequentially with different solventsThe antimicrobial and anticancer potential of macroalgae extracts were evaluatedEthyl acetate extract of H. grandifolius showed noticeable antifungal activity against all the fungal strains tested, including fluconazole-resistant samplesEthyl acetate extract of I. cordata was highly cytotoxic against the A-431 cancer cell lineMost of the algal extracts tested showed little or no cytotoxicity against normal cell lines. PMID- 29568292 TI - Arbuscular Mycorrhizal Fungi Negatively Affect Nitrogen Acquisition and Grain Yield of Maize in a N Deficient Soil. AB - Arbuscular mycorrhizal fungi (AMF) play a crucial role in enhancing the acquisition of immobile nutrients, particularly phosphorus. However, because nitrogen (N) is more mobile in the soil solution and easier to access by plants roots, the role of AMF in enhancing N acquisition is regarded as less important for host plants. Because AMF have a substantial N demand, competition for N between AMF and plants particularly under low N condition is possible. Thus, it is necessary to know whether or not AMF affect N uptake of plants and thereby affect plant growth under field conditions. We conducted a 2-year field trial and pot experiments in a greenhouse by using benomyl to suppress colonization of maize roots by indigenous AMF at both low and high N application rates. Benomyl reduced mycorrhizal colonization of maize plants in all experiments. Benomyl treated maize had a higher shoot N concentration and content and produced more grain under field conditions. Greenhouse pot experiments showed that benomyl also enhanced maize growth and N concentration and N content when the soil was not sterilized, but had no effect on maize biomass and N content when the soil was sterilized but a microbial wash added, providing evidence that increased plant performance is at least partly caused by direct effects of benomyl on AMF. We conclude that AMF can reduce N acquisition and thereby reduce grain yield of maize in N-limiting soils. PMID- 29568293 TI - Incomplete Selective Sweeps of Microcystis Population Detected by the Leader-End CRISPR Fragment Analysis in a Natural Pond. AB - The freshwater cyanobacterium Microcystis aeruginosa frequently forms toxic massive blooms and exists in an arms race with its infectious phages in aquatic natural environments, and as a result, has evolved extremely diverse and elaborate antiviral defense systems, including the clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated genes (Cas) system. Here, to assess Microcystis population dynamics associated with exogenous mobile genetic elements such as phages and plasmids, we examined the temporal variation in CRISPR genotypes (CTs) by analyzing spacer sequences detected in a natural pond between June and October 2013 when a cyanobacterial bloom occurred. A total of 463,954 high-quality leader-end CRISPR sequences were obtained and the sequences containing spacers were classified into 31 previously reported CTs and 68 new CTs based on the shared order of the leader-end spacers. CT19 was the most dominant genotype (32%) among the 16 most common CTs, followed by CT52 (14%) and CT58 (9%). Spacer repertoires of CT19 showed mainly two different types; CT19origin, which was identical to the CT19 spacer repertoire of previously isolated strains, and CT19new+, which contained a new spacer at the leader-end of the CRISPR region of CT19origin, which were present in almost equal abundance, accounting for up to 99.94% of CT19 sequences. Surprisingly, we observed the spacer repertoires of the second to tenth spacers of CT19origin at the most leader-end of proto-genotype sequences of CT19origin. These were observed during the sampling in this study and our previous study at the same ecosystem in 2010 and 2011, suggesting these CTs persisted from 2011 to 2013 in spite of phage pressure. The leader-end variants were observed in other CT genotypes. These findings indicated an incomplete selective sweep of Microcystis populations. We explained the phenomenon as follow; the abundance of Microcystis varied seasonally and drastically, resulting that Microcystis populations experience a bottleneck once a year, and thereby founder effects following a bottleneck mean that older CTs have an equal chance of increasing in prevalence as the CTs generated following acquisition of newer spacers. PMID- 29568294 TI - PlMAPK10, a Mitogen-Activated Protein Kinase (MAPK) in Peronophythora litchii, Is Required for Mycelial Growth, Sporulation, Laccase Activity, and Plant Infection. AB - Mitogen-activated protein kinase (MAPK) pathways are ubiquitous and evolutionarily conserved signal transduction modules directing cellular respond to a diverse array of stimuli, in the eukaryotic organisms. In this study, PlMAPK10 was identified to encode a MAPK in Peronophythora litchii, the oomycete pathogen causing litchi downy blight disease. PlMAPK10, containing a specific and highly conserved dual phosphorylation lip sequence SEY (Serine-Glutamic Tyrosine), represents a novel group of MAPKs as previously reported. Transcriptional profiling showed that PlMAPK10 expression was up-regulated in zoospore and cyst stages. To elucidate its function, the PlMAPK10 gene was silenced by stable transformation. PlMAPK10 silence did not impair oospore production, sporangium germination, zoospore encyst, or cyst germination but hindered hyphal growth, sporulation, pathogenicity, likely due to altering laccase activity. Over all, our results indicated that a MAPK encoded by PlMAPK10 gene in P. litchii is important for pathogenic development. PMID- 29568295 TI - Drosophila GATA Factor Serpent Establishes Phagocytic Ability of Embryonic Macrophages. AB - During Drosophila embryogenesis, a large number of apoptotic cells are efficiently engulfed and degraded by professional phagocytes, macrophages. Phagocytic receptors Six-Microns-Under (SIMU), Draper (Drpr) and Croquemort (Crq) are specifically expressed in embryonic macrophages and required for their phagocytic function. However, how this function is established during development remains unclear. Here we demonstrate that the key regulator of Drosophila embryonic hemocyte differentiation, the transcription factor Serpent (Srp), plays a central role in establishing macrophage phagocytic competence. Srp, a homolog of the mammalian GATA factors, is required and sufficient for the specific expression of SIMU, Drpr and Crq receptors in embryonic macrophages. Moreover, we show that each of these receptors can significantly rescue phagocytosis defects of macrophages in srp mutants, including their distribution in the embryo and engulfment of apoptotic cells. This reveals that the proficiency of macrophages to remove apoptotic cells relies on the expression of SIMU, Crq and/or Drpr. However, Glial Cells Missing (GCM) acting downstream of Srp in the differentiation of hemocytes, is dispensable for their phagocytic function during embryogenesis. Taken together, our study discloses the molecular mechanism underlying the development of macrophages as skilled phagocytes of apoptotic cells. PMID- 29568296 TI - Many Routes to an Antibody Heavy-Chain CDR3: Necessary, Yet Insufficient, for Specific Binding. AB - Because of its great potential for diversity, the immunoglobulin heavy-chain complementarity-determining region 3 (HCDR3) is taken as an antibody molecule's most important component in conferring binding activity and specificity. For this reason, HCDR3s have been used as unique identifiers to investigate adaptive immune responses in vivo and to characterize in vitro selection outputs where display systems were employed. Here, we show that many different HCDR3s can be identified within a target-specific antibody population after in vitro selection. For each identified HCDR3, a number of different antibodies bearing differences elsewhere can be found. In such selected populations, all antibodies with the same HCDR3 recognize the target, albeit at different affinities. In contrast, within unselected populations, the majority of antibodies with the same HCDR3 sequence do not bind the target. In one HCDR3 examined in depth, all target specific antibodies were derived from the same VDJ rearrangement, while non binding antibodies with the same HCDR3 were derived from many different V and D gene rearrangements. Careful examination of previously published in vivo datasets reveals that HCDR3s shared between, and within, different individuals can also originate from rearrangements of different V and D genes, with up to 26 different rearrangements yielding the same identical HCDR3 sequence. On the basis of these observations, we conclude that the same HCDR3 can be generated by many different rearrangements, but that specific target binding is an outcome of unique rearrangements and VL pairing: the HCDR3 is necessary, albeit insufficient, for specific antibody binding. PMID- 29568297 TI - NKG2D: A Master Regulator of Immune Cell Responsiveness. AB - NKG2D is an activating receptor that is mostly expressed on cells of the cytotoxic arm of the immune system. Ligands of NKG2D are normally of low abundance, but can be induced in virtually any cell in response to stressors, such as infection and oncogenic transformation. Engagement of NKG2D stimulates the production of cytokines and cytotoxic molecules and traditionally this receptor is, therefore, viewed as a molecule that mediates direct responses against cellular threats. However, accumulating evidence indicates that this classical view is too narrow. During NK cell development, engagement of NKG2D has a long-term impact on the expression of NK cell receptors and their responsiveness to extracellular cues, suggesting a role in NK cell education. Upon chronic NKG2D engagement, both NK and T cells show reduced responsiveness of a number of activating receptors, demonstrating a role of NKG2D in induction of peripheral tolerance. The image that emerges is that NKG2D can mediate both inhibitory and activating signals, which depends on the intensity and duration of ligand engagement. In this review, we provide an overview of the impact of NKG2D stimulation during hematopoietic development and during acute and chronic stimulation in the periphery on responsiveness of other receptors than NKG2D. We propose that NKG2D interprets the context of the immunological environment through detection of cellular cues and in response sets the appropriate activation threshold for a large number of immune receptors. This perspective is of particular importance for future therapies that aim to exploit NKG2D signaling to fight tumors or infection. PMID- 29568298 TI - Trying to See the Forest through the Trees: Deciphering the Nature of Memory Immunity to Mycobacterium tuberculosis. AB - The purpose of vaccination against tuberculosis and other diseases is to establish a heightened state of acquired specific resistance in which the memory immune response is capable of mediating an accelerated and magnified expression of protection to the pathogen when this is encountered at a later time. In the earliest studies in mice infected with Mycobacterium tuberculosis, memory immunity and the cells that express this were definable both in terms of kinetics of emergence, and soon thereafter by the levels of expression of markers including CD44, CD62L, and the chemokine receptor CCR7, allowing the identification of effector memory and central memory T cell subsets. Despite these initial advances in knowledge, more recent information has not revealed more clarity, but instead, has created a morass of complications-complications that, if not resolved, could harm correct vaccine design. Here, we discuss two central issues. The first is that we have always assumed that memory is induced in the same way, and consists of the same T cells, regardless of whether that immunity is generated by BCG vaccination, or by exposure to M. tuberculosis followed by effective chemotherapy. This assumption is almost certainly incorrect. Second, a myriad of additional memory subsets have now been described, such as resident, stem cell-like, tissue specific, among others, but as yet we know nothing about the relative importance of each, or whether if a new vaccine needs to induce all of these, or just some, to be fully effective. PMID- 29568299 TI - New Insights into Tumor-Infiltrating B Lymphocytes in Breast Cancer: Clinical Impacts and Regulatory Mechanisms. AB - Currently, tumor-infiltrating B lymphocytes have been recognized as a new hallmark of breast cancer (BC). The function seems to be controversial, either with positive, negative, or no significance in BC's prediction and prognosis. Moreover, B-cell infiltrates regulate tumor process through productions of antibodies and interleukin-10. The interactions with other lymphocytes and programmed death-1/PD-1 ligand axis are also documented. The regulatory mechanisms will eventually be incorporated into diagnostic and therapeutic algorithms, thus give guide to clinical treatment. In this review, we give new insights into clinical impacts and regulatory mechanisms of tumor-infiltrating B cells, which heralds a new era in immuno-oncology in BC treatment. PMID- 29568300 TI - Tailoring Immune Responses toward Autoimmunity: Transcriptional Regulators That Drive the Creation and Collusion of Autoreactive Lymphocytes. AB - T-dependent humoral immune responses to infection involve a collaboration between B and CD4 T cell activation, migration, and co-stimulation, thereby culminating in the formation of germinal centers (GCs) and eventual differentiation into memory cells and long-lived plasma cells (PCs). CD4 T cell-derived signals drive the formation of a tailored B cell response. Downstream of these signals are transcriptional regulators that are the critical enactors of immune cell programs. In particular, a core group of transcription factors regulate both B and T cell differentiation, identity, and function. The timing and expression levels of these transcription factors are tightly controlled, with dysregulated expression correlated to immune cell dysfunction in autoimmunity and lymphomagenesis. Recent studies have significantly advanced our understanding of both extrinsic and intrinsic regulators of autoreactive B cells and antibody secreting PCs in systemic lupus erythematosus, rheumatoid arthritis, and other autoimmune conditions. Yet, there are still gaps in our understanding of the causative role these regulators play, as well as the link between lymphoid responses and peripheral damage. This review will focus on the genesis of immunopathogenic CD4 helper and GC B cells. In particular, we will detail the transcriptional regulation of cytokine and chemokine receptor signaling during the pathogenesis of GC-derived autoimmune conditions in both murine models and human patients. PMID- 29568301 TI - Arabidopsis PCaP2 Plays an Important Role in Chilling Tolerance and ABA Response by Activating CBF- and SnRK2-Mediated Transcriptional Regulatory Network. AB - Chilling stress affects plant growth and productivity. However, the multi underlying mechanisms of chilling tolerance are not well understood. Arabidopsis PCaP2 is involved in regulating the dynamic of microtubules (MTs) and F-actin and Ca2+-binding ability. Here, the results showed that the PCaP2 expression was highly induced in roots, cotyledons, true leaves, lateral roots and flowers under cold stress. Compared with the wild type, PCaP2-overexpressing plants displayed the enhanced tolerance, whereas its RNAi and mutant were more sensitive in seed germination, seedling and reproductive growth under chilling stress in Arabidopsis. In addition, PCaP2 was also a positive regulator of ABA signaling pathway by analyzing the expression of PCaP2 and the phenotypes of PCaP2 overexpressing, mutant and RNAi plants under ABA treatment. Interestingly, disruption of PCaP2 inhibited the expression of CBF1, -3 and CBF-target COR genes, while increased the CBF2 expression in response to cold or ABA. Moreover, we found that SnRK2s were involved in cold stress and PCaP2 mutants down regulated the transcription level of SnRK2.2, -2.3 and SnRK2-mediated downstream genes including ABF2, RD29A, KIN1, KIN2, but up-regulated SnRK2.6, ABF1, -3, -4 in ABA and cold treatments. It is well-accepted that PCaP2 as a Ca2+-binding protein triggers the gene expression to enhance plant chilling tolerance. Our further studies showed that MT destabilizing activity of PCaP2, but not F-actin severing function, may be involved in chilling stress. Taken together, our results highlight that PCaP2 plays an important role in chilling tolerance and ABA response by triggering the CBF- and SnRK2-meditated transcriptional regulatory pathways, providing novel evidences of underlying mechanisms of multi pathways in chilling stress. PMID- 29568303 TI - European Forest Cover During the Past 12,000 Years: A Palynological Reconstruction Based on Modern Analogs and Remote Sensing. AB - Characterization of land cover change in the past is fundamental to understand the evolution and present state of the Earth system, the amount of carbon and nutrient stocks in terrestrial ecosystems, and the role played by land-atmosphere interactions in influencing climate. The estimation of land cover changes using palynology is a mature field, as thousands of sites in Europe have been investigated over the last century. Nonetheless, a quantitative land cover reconstruction at a continental scale has been largely missing. Here, we present a series of maps detailing the evolution of European forest cover during last 12,000 years. Our reconstructions are based on the Modern Analog Technique (MAT): a calibration dataset is built by coupling modern pollen samples with the corresponding satellite-based forest-cover data. Fossil reconstructions are then performed by assigning to every fossil sample the average forest cover of its closest modern analogs. The occurrence of fossil pollen assemblages with no counterparts in modern vegetation represents a known limit of analog-based methods. To lessen the influence of no-analog situations, pollen taxa were converted into plant functional types prior to running the MAT algorithm. We then interpolate site-specific reconstructions for each timeslice using a four dimensional gridding procedure to create continuous gridded maps at a continental scale. The performance of the MAT is compared against methodologically independent forest-cover reconstructions produced using the REVEALS method. MAT and REVEALS estimates are most of the time in good agreement at a trend level, yet MAT regularly underestimates the occurrence of densely forested situations, requiring the application of a bias correction procedure. The calibrated MAT based maps draw a coherent picture of the establishment of forests in Europe in the Early Holocene with the greatest forest-cover fractions reconstructed between ~8,500 and 6,000 calibrated years BP. This forest maximum is followed by a general decline in all parts of the continent, likely as a result of anthropogenic deforestation. The continuous spatial and temporal nature of our reconstruction, its continental coverage, and gridded format make it suitable for climate, hydrological, and biogeochemical modeling, among other uses. PMID- 29568302 TI - A Canonical DREB2-Type Transcription Factor in Lily Is Post-translationally Regulated and Mediates Heat Stress Response. AB - Based on studies of monocot crops and eudicot model plants, the DREB2 class of AP2-type transcription factor has been shown to play crucial roles in various abiotic stresses, especially in the upstream of the heat stress response; however, research on DREB2s has not been reported in non-gramineous monocot plants. Here, we identified a novel DREB2 (LlDREB2B) from lily (Lilium longiflorum), which was homologous to AtDREB2A of Arabidopsis, OsDREB2B of rice, and ZmDREB2A of maize. LlDREB2B was induced by heat, cold, salt, and mannitol stress, and its protein had transcriptional activity, was located in the nucleus, was able to bind to the dehydration-responsive element (DRE), and participated in the heat-responsive pathway of HsfA3. Overexpression of LlDREB2B in Arabidopsis activated expression of downstream genes and improved thermotolerance. LlDREB2B was not regulated by alternative splicing; functional transcripts accumulated under either normal or heat-stress conditions. A potential PEST sequence was predicted in LlDREB2B, but the stability of the LlDREB2B protein was not positively affected when the predicated PEST sequence was deleted. Further analysis revealed that the predicated PEST sequence lacked a SBC or SBC-like motif allowing interaction with BPMs and required for negative regulation. Nevertheless, LlDREB2B was still regulated at the post-translational level by interaction with AtDRIP1 and AtDRIP2 of Arabidopsis. In addition, LlDREB2B also interacted with AtRCD1 and LlRCD1 via a potential RIM motif located at amino acids 215-245. Taken together, our results show that LlDREB2B participated in the establishment of thermotolerance, and its regulation was different from that of the orthologs of gramineous and eudicot plants. PMID- 29568305 TI - Mapping the Flowering of an Invasive Plant Using Unmanned Aerial Vehicles: Is There Potential for Biocontrol Monitoring? AB - Invasion by alien species is a worldwide phenomenon with negative consequences at both natural and production areas. Acacia longifolia is an invasive shrub/small tree well known for its negative ecological impacts in several places around the world. The recent introduction of a biocontrol agent (Trichilogaster acaciaelongifoliae), an Australian bud-galling wasp which decreases flowering of A. longifolia, in Portugal, demands the development of a cost-efficient method to monitor its establishment. We tested how unmanned aerial vehicles (UAV) can be used to map A. longifolia flowering. Our core assumption is as the population of the biocontrol agent increases, its impacts on the reduction of A. longifolia flowering will be increasingly visible. Additionally, we tested if there is a simple linear correlation between the number of flowers of A. longifolia counted in field and the area covered by flowers in the UAV imagery. UAV imagery was acquired over seven coastal areas including frontal dunes, interior sand dunes and pine forests considering two phenological stages: peak and off-peak flowering season. The number of flowers of A. longifolia was counted, in a minimum of 60 1 m2 quadrats per study area. For each study area, flower presence/absence maps were obtained using supervised Random Forest. The correlation between the number of flowers and the area covered by flowering plants could then be tested. The flowering of A. longifolia was mapped using UAV mounted with RGB and CIR Cannon IXUS/ELPH cameras (Overall Accuracy > 0.96; Cohen's Kappa > 0.85) varying according to habitat type and flowering season. The correlation between the number of flowers counted and the area covered by flowering was weak (r2 between 0.0134 and 0.156). This is probably explained, at least partially, by the high variability of A. longifolia in what regards flowering morphology and distribution. The very high accuracy of our approach to map A. longifolia flowering proved to be cost efficient and replicable, showing great potential for detecting the future decrease in flowering promoted by the biocontrol agent. The attempt to provide a low-cost method to estimate A. longifolia flower productivity using UAV failed, but it provided valuable insights on the future steps. PMID- 29568304 TI - Early Cold-Induced Peroxidases and Aquaporins Are Associated With High Cold Tolerance in Dajiao (Musa spp. 'Dajiao'). AB - Banana is an important tropical fruit with high economic value. One of the main cultivars ('Cavendish') is susceptible to low temperatures, while another closely related specie ('Dajiao') has considerably higher cold tolerance. We previously reported that some membrane proteins appear to be involved in the cold tolerance of Dajiao bananas via an antioxidation mechanism. To investigate the early cold stress response of Dajiao, here we applied comparative membrane proteomics analysis for both cold-sensitive Cavendish and cold-tolerant Dajiao bananas subjected to cold stress at 10 degrees C for 0, 3, and 6 h. A total of 2,333 and 1,834 proteins were identified in Cavendish and Dajiao, respectively. Subsequent bioinformatics analyses showed that 692 Cavendish proteins and 524 Dajiao proteins were predicted to be membrane proteins, of which 82 and 137 differentially abundant membrane proteins (DAMPs) were found in Cavendish and Dajiao, respectively. Interestingly, the number of DAMPs with increased abundance following 3 h of cold treatment in Dajiao (80) was seven times more than that in Cavendish (11). Gene ontology molecular function analysis of DAMPs for Cavendish and Dajiao indicated that they belong to eight categories including hydrolase activity, binding, transporter activity, antioxidant activity, etc., but the number in Dajiao is twice that in Cavendish. Strikingly, we found peroxidases (PODs) and aquaporins among the protein groups whose abundance was significantly increased after 3 h of cold treatment in Dajiao. Some of the PODs and aquaporins were verified by reverse-transcription PCR, multiple reaction monitoring, and green fluorescent protein-based subcellular localization analysis, demonstrating that the global membrane proteomics data are reliable. By combining the physiological and biochemical data, we found that membrane-bound Peroxidase 52 and Peroxidase P7, and aquaporins (MaPIP1;1, MaPIP1;2, MaPIP2;4, MaPIP2;6, MaTIP1;3) are mainly involved in decreased lipid peroxidation and maintaining leaf cell water potential, which appear to be the key cellular adaptations contributing to the cold tolerance of Dajiao. This membrane proteomics study provides new insights into cold stress tolerance mechanisms of banana, toward potential applications for ultimate genetic improvement of cold tolerance in banana. PMID- 29568306 TI - Can Leaf Water Content Be Estimated Using Multispectral Terrestrial Laser Scanning? A Case Study With Norway Spruce Seedlings. AB - Changing climate is increasing the amount and intensity of forest stress agents, such as drought, pest insects, and pathogens. Leaf water content, measured here in terms of equivalent water thickness (EWT), is an early indicator of tree stress that provides timely information about the health status of forests. Multispectral terrestrial laser scanning (MS-TLS) measures target geometry and reflectance simultaneously, providing spatially explicit reflectance information at several wavelengths. EWT and leaf internal structure affect leaf reflectance in the shortwave infrared region that can be used to predict EWT with MS-TLS. A second wavelength that is sensitive to leaf internal structure but not affected by EWT can be used to normalize leaf internal effects on the shortwave infrared region and improve the prediction of EWT. Here we investigated the relationship between EWT and laser intensity features using multisensor MS-TLS at 690, 905, and 1,550 nm wavelengths with both drought-treated and Endoconidiophora polonica inoculated Norway spruce seedlings to better understand how MS-TLS measurements can explain variation in EWT. In our study, a normalized ratio of two wavelengths at 905 and 1,550 nm and length of seedling explained 91% of the variation (R2) in EWT as the respective prediction accuracy for EWT was 0.003 g/cm2 in greenhouse conditions. The relation between EWT and the normalized ratio of 905 and 1,550 nm wavelengths did not seem sensitive to a decreased point density of the MS-TLS data. Based on our results, different EWTs in Norway spruce seedlings show different spectral responses when measured using MS-TLS. These results can be further used when developing EWT monitoring for improving forest health assessments. PMID- 29568307 TI - Two Splicing Variants of OsNPF7.7 Regulate Shoot Branching and Nitrogen Utilization Efficiency in Rice. AB - Rice includes 93 nitrate and peptide transporters family (NPF) members that facilitate the soil uptake and internal reallocation of nitrogen for growth and development. This study demonstrated that OsNPF7.7 had two splicing variants, and altered expression of each variant could regulate shoot branching and nitrogen utilization efficiency (NUtE) in rice. The expression of both variants was down regulated in the buds by increased nitrogen level in the Japonica rice variety ZH11. The expression level of long-variant OsNPF7.7-1 was higher in panicles at reproductive stage, however, the expression level of short-variant OsNPF7.7-2 was higher in buds and leaves at vegetative stage compared to each other in ZH11. OsNPF7.7-1 was localized in the plasma membrane, whereas OsNPF7.7-2 was localized in the vacuole membrane. Furthermore, the results indicated that the expression level of each variant for OsNPF7.7 determined axillary bud outgrowth, and then influenced the rice tiller number. Overexpression of OsNPF7.7-1 could promote nitrate influx and concentration in root, whereas overexpression of OsNPF7.7-2 could improve ammonium influx and concentration in root. RNAi and osnpf7.7 lines of OsNPF7.7 showed an increased amount of amino acids in leaf sheaths, but a decreased amount in leaf blades, which affected nitrogen allocation and plant growth. The elevated expression of each variant for OsNPF7.7 in ZH11 enhanced NUtE using certain fertilization regimes under paddy field conditions. Moreover, overexpression of each variant for OsNPF7.7 in KY131 increased significantly the filled grain number per plant. Thus, increased each variant of OsNPF7.7 has the potential to improve grain yield and NUtE in rice. PMID- 29568308 TI - Plant Glycine-Rich Proteins in Stress Response: An Emerging, Still Prospective Story. AB - Seed plants are sessile organisms that have developed a plethora of strategies for sensing, avoiding, and responding to stress. Several proteins, including the glycine-rich protein (GRP) superfamily, are involved in cellular stress responses and signaling. GRPs are characterized by high glycine content and the presence of conserved segments including glycine-containing structural motifs composed of repetitive amino acid residues. The general structure of this superfamily facilitates division of GRPs into five main subclasses. Although the participation of GRPs in plant stress response has been indicated in numerous model and non-model plant species, relatively little is known about the key physiological processes and molecular mechanisms in which those proteins are engaged. Class I, II, and IV members are known to be involved in hormone signaling, stress acclimation, and floral development, and are crucial for regulation of plant cells growth. GRPs of class IV [RNA-binding proteins (RBPs)] are involved in alternative splicing or regulation of transcription and stomatal movement, seed, pollen, and stamen development; their accumulation is regulated by the circadian clock. Owing to the fact that the overexpression of GRPs can confer tolerance to stress (e.g., some are involved in cold acclimation and may improve growth at low temperatures), these proteins could play a promising role in agriculture through plant genetic engineering. Consequently, isolation, cloning, characterization, and functional validation of novel GRPs expressed in response to the diverse stress conditions are expected to be growing areas of research in the coming years. According to our knowledge, this is the first comprehensive review on participation of plant GRPs in the response to diverse stress stimuli. PMID- 29568309 TI - Recurrent Transformation of Prior Knowledge Based Model for Human Motion Recognition. AB - Motion related human activity recognition using wearable sensors can potentially enable various useful daily applications. So far, most studies view it as a stand alone mathematical classification problem without considering the physical nature and temporal information of human motions. Consequently, they suffer from data dependencies and encounter the curse of dimension and the overfitting issue. Their models are hard to be intuitively understood. Given a specific motion set, if structured domain knowledge could be manually obtained, it could be used for better recognizing certain motions. In this study, we start from a deep analysis on natural physical properties and temporal recurrent transformation possibilities of human motions and then propose a useful Recurrent Transformation Prior Knowledge-based Decision Tree (RT-PKDT) model for recognition of specific human motions. RT-PKDT utilizes temporal information and hierarchical classification method, making the most of sensor streaming data and human knowledge to compensate the possible data inadequacy. The experiment results indicate that the proposed method performs superior to those adopted in related works, such as SVM, BP neural networks, and Bayesian Network, obtaining an accuracy of 96.68%. PMID- 29568310 TI - n-Iterative Exponential Forgetting Factor for EEG Signals Parameter Estimation. AB - Electroencephalograms (EEG) signals are of interest because of their relationship with physiological activities, allowing a description of motion, speaking, or thinking. Important research has been developed to take advantage of EEG using classification or predictor algorithms based on parameters that help to describe the signal behavior. Thus, great importance should be taken to feature extraction which is complicated for the Parameter Estimation (PE)-System Identification (SI) process. When based on an average approximation, nonstationary characteristics are presented. For PE the comparison of three forms of iterative-recursive uses of the Exponential Forgetting Factor (EFF) combined with a linear function to identify a synthetic stochastic signal is presented. The one with best results seen through the functional error is applied to approximate an EEG signal for a simple classification example, showing the effectiveness of our proposal. PMID- 29568311 TI - Enhanced Ant Colony Optimization with Dynamic Mutation and Ad Hoc Initialization for Improving the Design of TSK-Type Fuzzy System. AB - This paper proposes an enhanced ant colony optimization with dynamic mutation and ad hoc initialization, ACODM-I, for improving the accuracy of Takagi-Sugeno-Kang- (TSK-) type fuzzy systems design. Instead of the generic initialization usually used in most population-based algorithms, ACODM-I proposes an ad hoc application specific initialization for generating the initial ant solutions to improve the accuracy of fuzzy system design. The generated initial ant solutions are iteratively improved by a new approach incorporating the dynamic mutation into the existing continuous ACO (ACOR). The introduced dynamic mutation balances the exploration ability and convergence rate by providing more diverse search directions in the early stage of optimization process. Application examples of two zero-order TSK-type fuzzy systems for dynamic plant tracking control and one first-order TSK-type fuzzy system for the prediction of the chaotic time series have been simulated to validate the proposed algorithm. Performance comparisons with ACOR and different advanced algorithms or neural-fuzzy models verify the superiority of the proposed algorithm. The effects on the design accuracy and convergence rate yielded by the proposed initialization and introduced dynamic mutation have also been discussed and verified in the simulations.

AB - This study aimed to determine the prevalence of H. pylori infections among schoolchildren and investigate the associations between H. pylori seropositivity and existence of gastrointestinal symptoms. Methods. A prospective cross sectional study was conducted during a period from January to December 2012 at Kassala state, east of Sudan. Schoolchildren from different primary schools were enrolled in the study. Sociodemographic characteristics and gastrointestinal symptoms were recorded from each child. A rapid immunochromatographic test was performed for the detection of H. pylori IgG antibodies. Data on patient demographic characteristics, clinical diagnosis, and findings of H. pylori infection were analyzed by simple descriptive statistics. Results. Among 431 schoolchildren, H. pylori seropositivity was found to be 21.8%. The majority of children (79; 84%) had BMI below the normal range. The most frequent symptoms associated with H. pylori infections were nausea (25.5%), followed by gastric pain (24.5%) and heart pain (20.2%). There were statistically significant differences in H. pylori seropositivity between boys and girls (p = 0.003). Conclusions. The prevalence of H. pylori infection among schoolchildren in Kassala city has been documented. Although the majority of the disease was associated with several gastrointestinal symptoms, the role of infection in the etiology of abdominal symptoms needs further investigations. PMID- 29568313 TI - The in vitro effects of a novel estradiol analog on cell proliferation and morphology in human epithelial cervical carcinoma. AB - Background: The majority of novel chemotherapeutics target the cell cycle, aiming to effect arrest and cause apoptosis. One such agent, 2-methoxyestradiol (2ME), has been shown to possess anticancer properties against numerous cancer types, both in vitro and in vivo. Despite its promise, 2ME has exhibited limitations, including low oral bioavailability and rapid hepatic enzymatic inactivation in vivo. A novel sulphamoylated estrogen analog, 2-ethyl-3-O-sulphamoyl-estra 1,3,5(10)16-tetraene (ESE-16), was in silico-designed in our laboratory to overcome these issues. It was then synthesized by a pharmaceutical company and used in an in vitro antiproliferative effect study on a human cervical carcinoma (HeLa) cell line. Results: Cell proliferation data obtained from the crystal violet assay and real-time cell analysis demonstrated that 0.2 MUM of ESE-16 had a significant inhibitory effect on the HeLa cells 24 h post-exposure. Immunofluorescence showed that ESE-16 is a microtubule disruptor that causes cells to undergo a mitotic block. Qualitative morphological studies using polarization-optical transmitted light differential interference contrast (PlasDIC) and light microscopy revealed a decrease in cell density and an increase in the number of cells arrested in metaphase. After ESE-16 exposure, hallmarks of apoptosis were also observed, including membrane blebbing, chromatin condensation and the presence of apoptotic bodies. Flow cytometry provided quantitative results from cell cycle progression analysis, indicating cells undergoing apoptosis and cells in the G2/M phase of the cell cycle, confirming cell cycle arrest in metaphase after ESE-16 treatment. Quantification of the ESE 16-mediated upregulation of cyclin B in HeLa cells and spectrophotometric and flow cytometric confirmation of cell death via apoptosis further confirmed the substance's impact. Conclusion: ESE-16 exerts its antiproliferative effects through microtubule disruption, which induces a mitotic block culminating in apoptosis. This research provided information on ESE-16 as a potential antitumor agent and on cellular targets that could aid in the design of prospective microtubule-disrupting compounds. Further in vitro and in vivo investigations of this novel compound are needed. PMID- 29568314 TI - Platelet lysate induces chondrogenic differentiation of umbilical cord-derived mesenchymal stem cells. AB - Purpose: Articular cartilage has a poor capacity for self-repair, and thus still presents a major challenge in orthopedics. Mesenchymal stem cells (MSCs) are multipotent stem cells with the potential to differentiate into chondrocytes in the presence of transforming growth factor beta (TGF-beta). Platelet lysate (PL) contains a relatively large number of growth factors, including TGF-beta, and has been shown to ameliorate cartilage repair. Here, we investigated the ability of PL to direct chondrogenic differentiation of MSCs along with other standard differentiation components in a pellet culture system. Methods: We isolated and expanded MSCs from human umbilical cords using a PL-supplemented medium and characterized the cells based on immunophenotype and potential for differentiation to adipocytes and osteocytes. We further cultured MSCs as pellets in a chondrogenic-differentiation medium supplemented with PL. After 21 days, the pellets were processed for histological analysis and stained with alician blue and acridine orange. The expression of SOX9 was investigated using RT-PCR. Results: MSCs maintained their stemness characteristics in the PL-supplemented medium. However, the distribution of cells in the pellets cultured in the PL supplemented chondrogenic differentiation medium had a greater similarity to cartilage tissue-derived chondrocytes than to the negative control. The intense alician blue staining indicated an increased production of mucopolysaccharides in the differentiated pellets, which also showed elevated expression of SOX9. Conclusions: Our data suggest that MSCs could be differentiated to chondrocytes in the presence of PL and absence of exogenous TGF-beta. Further research needs to be conducted to understand the exact role and potential of PL in chondrogenic differentiation and chondrocyte regeneration. PMID- 29568315 TI - Feeding ecology in sea spiders (Arthropoda: Pycnogonida): what do we know? AB - Sea spiders (Pycnogonida) are a widespread and phylogenetically important group of marine arthropods. However, their biology remains understudied, and detailed information about their feeding ecology is difficult to find. Observations on pycnogonid feeding are scattered in the literature, often in older sources written in various languages, and have never been comprehensively summarized. Here we provide an overview of all information on feeding in pycnogonids that we have been able to find and review what is known on feeding specializations and preferences in the various pycnogonid taxa. We deduce general findings where possible and outline future steps necessary to gain a better understanding of the feeding ecology of one of the world's most bizarre animal taxa. PMID- 29568316 TI - Chemical and behavioral integration of army ant-associated rove beetles - a comparison between specialists and generalists. AB - Host-symbiont interactions are embedded in ecological communities and range from unspecific to highly specific relationships. Army ants and their arthropod guests represent a fascinating example of species-rich host-symbiont associations where host specificity ranges across the entire generalist - specialist continuum. In the present study, we compared the behavioral and chemical integration mechanisms of two extremes of the generalist - specialist continuum: generalist ant predators in the genus Tetradonia (Staphylinidae: Aleocharinae: Athetini), and specialist ant-mimics in the genera Ecitomorpha and Ecitophya (Staphylinidae: Aleocharinae: Ecitocharini). Similar to a previous study of Tetradonia beetles, we combined DNA barcoding with morphological studies to define species boundaries in ant-mimicking beetles. This approach found four ant-mimicking species at our study site at La Selva Biological Station in Costa Rica. Community sampling of Eciton army ant parasites revealed that ant-mimicking beetles were perfect host specialists, each beetle species being associated with a single Eciton species. These specialists were seamlessly integrated into the host colony, while generalists avoided physical contact to host ants in behavioral assays. Analysis of the ants' nestmate recognition cues, i.e. cuticular hydrocarbons (CHCs), showed close similarity in CHC composition and CHC concentration between specialists and Eciton burchellii foreli host ants. On the contrary, the chemical profiles of generalists matched host profiles less well, indicating that high accuracy in chemical host resemblance is only accomplished by socially integrated species. Considering the interplay between behavior, morphology, and cuticular chemistry, specialists but not generalists have cracked the ants' social code with respect to various sensory modalities. Our results support the long-standing idea that the evolution of host-specialization in parasites is a trade-off between the range of potential host species and the level of specialization on any particular host. PMID- 29568317 TI - Rapeseed oil fortified with micronutrients can reduce glucose intolerance during a high fat challenge in rats. AB - Background: Better choices of dietary lipid sources and substitution of refined by fortified oils could reduce the intake of saturated fatty acids (FA) and increase the intake of omega 3 FA concomitantly to healthy bioactive compounds. Methods: The development of obesity and metabolic disturbances was explored in rats fed during 11 weeks with a high fat diet (HFD) in which the amount of saturated and polyunsaturated FA was respectively reduced and increased, using rapeseed oil as lipid source. This oil was used in a refined form (R) or fortified (10 fold increase in concentration) with endogenous micronutrients (coenzyme Q10 + tocopherol only (RF) only and also with canolol (RFC)). The effect of substituting palm by rapeseed oil was analysed using a student t test, oil fortification was analysed using ANOVA statistical test. Results: Despite a similar weight gain, diets R, RF and RFC improved glucose tolerance (+ 10%) of the rats compared to a standard HFD with palm and sunflower oils as lipid source. Plasma glucose was lowered in RF and RFC groups (- 15 and 23% respectively), although triacylglycerol level was only reduced in group RFC (- 33%) compared to R. The fortification with canolol promoted the activation of Akt and AMP activated protein kinase (AMPK) in skeletal muscle and subcutaneous adipose tissue respectively. Canolol supplementation also led to reduce p38 MAPK activation in skeletal muscle. Conclusions: This study suggests that the presence of endogenous micronutrients in rapeseed oil promotes cellular adaptations to reverse glucose intolerance and improve the metabolism of insulin sensitive tissues. PMID- 29568318 TI - An innovative light chamber for measuring photosynthesis by three-dimensional plant organs. AB - Background: In plants, three-dimensional (3-D) organs such as inflorescences or fruits carry out photosynthesis and thus play a significant role in carbon assimilation and yield. However, this contribution has been poorly characterized because there is no reliable method for measuring photosynthesis by 3-D organs. One of the major challenges is ensuring the uniform irradiation of samples that are placed within a sealed chamber. Results: In this study, we developed an innovative chamber with homogeneous lighting that can be used to measure photosynthesis by large 3-D organs. It consisted of a 15-cm-long sealed transparent cylinder that was surrounded by a decagonal prismatic light source, made up of a mixture of red and blue LEDs. We characterized irradiance homogeneity within the chamber at a resolution level of 1 cm and 10 degrees . Photosynthetic photon flux density (PPFD) along the central axis of the chamber could be set to any value between 100 and 1100 umol m-2 s-1. The coefficient of variation for the irradiation values found throughout the chamber was 10% and that for the ratio of red-to-blue spectra was less than 1.5%. The temperature of the sample was regulated to stay within 1 degrees C of the target temperature, regardless of PPFD. We compared the performance of our device with that of a commercially available device employing unidirectional lighting. Specifically, we examined net photosynthesis in two sample types-wheat ears and grape clusters-at varying PPFD levels. Conclusions: The devices gave similar estimates of dark respiration, regardless of sample type or age. Conversely, net photosynthesis started to become asymptotic at lower irradiance levels in our device than in the conventional device because apparent quantum yield was three times higher. When examining the effects of irradiance heterogeneity, it was clear that biased estimates could result from systems employing unidirectional light sources. Our results also confirmed that our chamber could be a useful tool for obtaining more accurate estimates of photosynthesis by 3-D organs. PMID- 29568319 TI - Wheat ear counting in-field conditions: high throughput and low-cost approach using RGB images. AB - Background: The number of ears per unit ground area (ear density) is one of the main agronomic yield components in determining grain yield in wheat. A fast evaluation of this attribute may contribute to monitoring the efficiency of crop management practices, to an early prediction of grain yield or as a phenotyping trait in breeding programs. Currently the number of ears is counted manually, which is time consuming. Moreover, there is no single standardized protocol for counting the ears. An automatic ear-counting algorithm is proposed to estimate ear density under field conditions based on zenithal color digital images taken from above the crop in natural light conditions. Field trials were carried out at two sites in Spain during the 2014/2015 crop season on a set of 24 varieties of durum wheat with two growing conditions per site. The algorithm for counting uses three steps: (1) a Laplacian frequency filter chosen to remove low and high frequency elements appearing in an image, (2) a Median filter to reduce high noise still present around the ears and (3) segmentation using Find Maxima to segment local peaks and determine the ear count within the image. Results: The results demonstrate high success rate (higher than 90%) between the algorithm counts and the manual (image-based) ear counts, and precision, with a low standard deviation (around 5%). The relationships between algorithm ear counts and grain yield was also significant and greater than the correlation with manual (field-based) ear counts. In this approach, results demonstrate that automatic ear counting performed on data captured around anthesis correlated better with grain yield than with images captured at later stages when the low performance of ear counting at late grain filling stages was associated with the loss of contrast between canopy and ears. Conclusions: Developing robust, low-cost and efficient field methods to assess wheat ear density, as a major agronomic component of yield, is highly relevant for phenotyping efforts towards increases in grain yield. Although the phenological stage of measurements is important, the robust image analysis algorithm presented here appears to be amenable from aerial or other automated platforms. PMID- 29568321 TI - Evaluation of Treatment Effect with Paired Failure Times in a Single-Arm Phase II Trial in Oncology. AB - In early phase clinical trials of cytotoxic drugs in oncology, the efficacy is typically evaluated based on the tumor shrinkage. However, this criterion is not always appropriate for more recent cytostatic agents, and alternative endpoints have been proposed. The growth modulation index (GMI), defined as the ratio between the times to progression in two successive treatment lines, has been proposed for a single-arm phase II trials. The treatment effect is evaluated by estimating the rate of patients having a GMI superior to a given threshold. To estimate this rate, we investigated a parametric method based on the distribution of the times to progression and a nonparametric one based on a midrank estimator. Through simulations, we studied their operating characteristics and the impact of different design parameters (censoring, dependence, and distribution) on them. In these simulations, the nonparametric estimator slightly underestimated the rate and had slightly overconservative confidence intervals in some cases. Conversely, the parametric estimator overestimated the rate and had anticonservative confidence intervals in some cases. The nonparametric method appeared to be more robust to censoring than the parametric one. In conclusion, we recommend the nonparametric method, but the parametric method can be used as a supplementary tool. PMID- 29568320 TI - Protein arginine methylation: an emerging regulator of the cell cycle. AB - Protein arginine methylation is a common post-translational modification where a methyl group is added onto arginine residues of a protein to alter detection by its binding partners or regulate its activity. It is known to be involved in many biological processes, such as regulation of signal transduction, transcription, facilitation of protein-protein interactions, RNA splicing and transport. The enzymes responsible for arginine methylation, protein arginine methyltransferases (PRMTs), have been shown to methylate or associate with important regulatory proteins of the cell cycle and DNA damage repair pathways, such as cyclin D1, p53, p21 and the retinoblastoma protein. Overexpression of PRMTs resulting in aberrant methylation patterns in cancers often correlates with poor recovery prognosis. This indicates that protein arginine methylation is also an important regulator of the cell cycle, and consequently a target for cancer regulation. The effect of protein arginine methylation on the cell cycle and how this emerging key player of cell cycle regulation may be used in therapeutic strategies for cancer are the focus of this review. PMID- 29568322 TI - Modelling of Soft Connective Tissues to Investigate Female Pelvic Floor Dysfunctions. AB - After menopause, decreased levels of estrogen and progesterone remodel the collagen of the soft tissues thereby reducing their stiffness. Stress urinary incontinence is associated with involuntary urine leakage due to pathological movement of the pelvic organs resulting from lax suspension system, fasciae, and ligaments. This study compares the changes in the orientation and position of the female pelvic organs due to weakened fasciae, ligaments, and their combined laxity. A mixture theory weighted by respective volume fraction of elastin collagen fibre compound (5%), adipose tissue (85%), and smooth muscle (5%) is adopted to characterize the mechanical behaviour of the fascia. The load carrying response (other than the functional response to the pelvic organs) of each fascia component, pelvic organs, muscles, and ligaments are assumed to be isotropic, hyperelastic, and incompressible. Finite element simulations are conducted during Valsalva manoeuvre with weakened tissues modelled by reduced tissue stiffness. A significant dislocation of the urethrovesical junction is observed due to weakness of the fascia (13.89 mm) compared to the ligaments (5.47 mm). The dynamics of the pelvic floor observed in this study during Valsalva manoeuvre is associated with urethral-bladder hypermobility, greater levator plate angulation, and positive Q-tip test which are observed in incontinent females. PMID- 29568323 TI - OCTAL: Optimal Completion of gene trees in polynomial time. AB - Background: For a combination of reasons (including data generation protocols, approaches to taxon and gene sampling, and gene birth and loss), estimated gene trees are often incomplete, meaning that they do not contain all of the species of interest. As incomplete gene trees can impact downstream analyses, accurate completion of gene trees is desirable. Results: We introduce the Optimal Tree Completion problem, a general optimization problem that involves completing an unrooted binary tree (i.e., adding missing leaves) so as to minimize its distance from a reference tree on a superset of the leaves. We present OCTAL, an algorithm that finds an optimal solution to this problem when the distance between trees is defined using the Robinson-Foulds (RF) distance, and we prove that OCTAL runs in [Formula: see text] time, where n is the total number of species. We report on a simulation study in which gene trees can differ from the species tree due to incomplete lineage sorting, and estimated gene trees are completed using OCTAL with a reference tree based on a species tree estimated from the multi-locus dataset. OCTAL produces completed gene trees that are closer to the true gene trees than an existing heuristic approach in ASTRAL-II, but the accuracy of a completed gene tree computed by OCTAL depends on how topologically similar the reference tree (typically an estimated species tree) is to the true gene tree. Conclusions: OCTAL is a useful technique for adding missing taxa to incomplete gene trees and provides good accuracy under a wide range of model conditions. However, results show that OCTAL's accuracy can be reduced when incomplete lineage sorting is high, as the reference tree can be far from the true gene tree. Hence, this study suggests that OCTAL would benefit from using other types of reference trees instead of species trees when there are large topological distances between true gene trees and species trees. PMID- 29568324 TI - The role of bacteria in cancer therapy - enemies in the past, but allies at present. AB - In recent decades, bacteria's therapeutic role has aroused attention in medicinal and pharmaceutical research. While bacteria are considered among the primary agents for causing cancer, recent research has shown intriguing results suggesting that bacteria can be effective agents for cancer treatment - they are the perfect vessels for targeted cancer therapy. Several bacterial strains/species have been discovered to possess inherent oncolytic potentials to invade and colonize solid tumors in vivo. The therapeutic strategy of using bacteria for treating cancer is considered to be effective; however, the severe side effects encountered during the treatment resulted in the abandonment of the therapy. State-of-the-art genetic engineering has been recently applied to bacteria therapy and resulted in a greater efficacy with minimum side effects. In addition, the anti-cancer potential of tumor-targeting bacteria through oral administration circumvents the use of the intravenous route and the associated adverse effects. This review aims to provide a comprehensive summary of the latest literature on the role of bacteria in cancer treatment.

AB - Background: It has been estimated that more than 200 million children under the age of five do not reach their full potential in cognitive development. Much of what we know about brain development is based on research from high-income countries. There is limited evidence on the determinants of early child development in low-income countries, especially rural sub-Saharan Africa. The present study aimed to identify the determinants of cognitive development in children living in villages surrounding Haydom, a rural area in north-central Tanzania. Methods: This cohort study is part of the MAL-ED (The Interactions of Malnutrition & Enteric Infections: Consequences for Child Health and Development) multi-country consortium studying risk factors for ill health and poor development in children. Descriptive analysis and linear regression analyses were performed. Associations between nutritional status, socio-economic status, and home environment at 6 months of age and cognitive outcomes at 15 months of age were studied. The third edition of the Bayley Scales for Infant and Toddler Development was used to assess cognitive, language and motor development. Results: There were 262 children enrolled into the study, and this present analysis included the 137 children with data for 15-month Bayley scores. Univariate regression analysis, weight-for-age and weight-for-length z-scores at 6 months were significantly associated with 15-month Bayley gross motor score, but not with other 15-month Bayley scores. Length-for-age z-scores at 6 months were not significantly associated with 15-month Bayley scores. The socio-economic status, measured by a set of assets and monthly income was significantly associated with 15-month Bayley cognitive score, but not with language, motor, nor total 15-month Bayley scores. Other socio-economic variables were not significantly associated with 15-month Bayley scores. No significant associations were found between the home environment and 15-month Bayley scores. In multivariate regression analyses we found higher Bayley scores for girls and higher Bayley scores in families with more assets. Adjusted R-squared of this model was 8%. Conclusion: We conclude that poverty is associated with a slower cognitive development in children and malnutrition is associated with slower gross motor development. This information should encourage authorities and other stakeholders to invest in improved welfare and nutrition programmes for children from early infancy. PMID- 29568328 TI - Nusinersen for spinal muscular atrophy. PMID- 29568327 TI - Synthetic pathways and processes for effective production of 5-hydroxytryptophan and serotonin from glucose in Escherichia coli. AB - Background: Tryptophan derivatives such as 5-hydroxytryptophan (5HTP) and serotonin are valuable molecules with pharmaceutical interest. 5HTP is presently mainly obtained by extraction from the plant Griffonia simplicifolia and serotonin is produced by chemical synthesis. A simple biotechnological method for the production of these compounds is desired. Results: In a first attempt to synthesize serotonin from glucose, we used a single engineered Escherichia coli strain and observed a low production of maximal 0.8 +/- 0.2 mg/L of serotonin, probably due to the undesired site-reaction of direct decarboxylation of tryptophan and the consequent decrease of the precursor 5HTP. To circumvent this problem, we have constructed a stepwise system in which the 5HTP production and the serotonin conversion are separated. 962 +/- 58 mg/L of 5HTP was produced in the first step using a recombinant strain with a semi-rationally engineered aromatic amino acid hydroxylase, the highest concentration reported so far. In a subsequent step of 5HTP bioconversion using a recombinant strain harboring a tryptophan decarboxylase, 154.3 +/- 14.3 mg/L of serotonin was produced. Conclusions: We present results of a two-stage fermentation process for the production of 5HTP and serotonin. The first strain is a highly efficient 5HTP producer, and after fermentation the supernatant is separated and used for the production of serotonin. This is the first report for the microbial production of serotonin from glucose. PMID- 29568329 TI - Differential immunological profiles herald magnetic resonance imaging-defined perioperative cerebral infarction. AB - Background: The perioperative period is associated with a high risk for human ischaemic stroke. Although inflammatory mechanisms are known to have an important role in cerebral infarction in the nonoperative setting, their role in modulating perioperative risk remains unclear. Methods: In this prospective case-control study, we compared 10 patients (cases) who developed magnetic resonance imaging (MRI) evidence of cerebral infarction following transcatheter aortic valve implantation with 10 patients (controls) who underwent the same procedure without neurological complication. Blood sampling was performed preoperatively (baseline) and at 24 h, 48 h and 72 h postoperatively and analysed for specific cytokines, chemokines and complement factors. Results: Baseline serum assessments identified significant differences between the two cohorts for levels of complement C3, complement C4b, granulocyte-macrophage colony-stimulating factor, interleukin-15 and macrophage inflammatory protein-1beta. Longitudinal regression analysis and best-fit polynomial curves of postoperative analyte profiles identified significantly higher levels of complement C3 and matrix metalloproteinase-9, and lower levels of interferon-gamma and macrophage inflammatory protein-1beta levels in cases versus controls. Conclusions: These results support a potentially important role for inflammatory mechanisms in MRI-defined perioperative stroke and reveal a potentially important role for complement components in this process. PMID- 29568330 TI - Antioxidant effects of vitamins in type 2 diabetes: a meta-analysis of randomized controlled trials. AB - Background: Vitamins are essential micronutrients with antioxidant potential that may provide a complementary treatment for patients with chronic diseases. Our aim was to assess the effect of vitamin supplementation on the antioxidant status and glycemic index of type 2 diabetes mellitus patients. Methods: We performed a systematic review with meta-analyses. Electronic searches were conducted in PubMed, Scopus, and Web of Science (December 2017). Randomized controlled trials evaluating the effect of any vitamin or vitamin complex supplementation on antioxidant status as primary outcome were included. The outcomes considered were: reduction of malondialdehyde (MDA); augmentation of glutathione peroxidase (GPx); changes in total antioxidant capacity (TAC), enhance in superoxide dismutase enzyme-SOD, and thiobarbituric acid reactive substances (TBARS). Outcomes of glycemic control were also evaluated. Pairwise meta-analyses were performed using software Review Manager 5.3. Results: Thirty trials fulfilled the inclusion criteria, but only 12 could be included in the meta-analyses of antioxidant outcomes. The most commonly studied vitamins were B, C, D and E. Vitamin E was related to significant reduction of blood glucose as well as glycated hemoglobin compared to placebo, while both vitamins C and E were mainly associated with reducing MDA and TBARS and elevating GPx, SOD and TAC, compared to placebo. However, outcome reports in this field are still inconsistent (e.g. because of a lack of standard measures). Conclusions: Supplementation of vitamin E may be a valuable strategy for controlling diabetes complications and enhancing antioxidant capacity. The effects of other micronutrients should be further investigated in larger and well-designed trials to properly place these complementary therapies in clinical practice. PMID- 29568331 TI - Impact of diabetes mellitus on ischemic cardiomyopathy. Five-year follow-up. REVISION-DM trial. AB - Background: Patients with ischemic cardiomyopathy and severe left ventricular dysfunction have a worse survival prognosis than patients with preserved ventricular function. The role of diabetes in the long-term prognosis of this patient group is unknown. This study investigated whether the presence of diabetes has a long-term impact on left ventricular function. Methods: Patients with coronary artery disease who underwent coronary artery bypass graft surgery, percutaneous coronary intervention, or medical therapy alone were included. All patients had multivessel disease and left ventricular ejection fraction measurements. Overall mortality, nonfatal myocardial infarction, stroke, and additional interventions were investigated. Results: From January 2009 to January 2010, 918 consecutive patients were selected and followed until May 2015. They were separated into 4 groups: G1, 266 patients with diabetes and ventricular dysfunction; G2, 213 patients with diabetes without ventricular dysfunction; G3, 213 patients without diabetes and ventricular dysfunction; and G4, 226 patients without diabetes but with ventricular dysfunction. Groups 1, 2, 3, and 4, respectively, had a mortality rate of 21.6, 6.1, 4.2, and 10.6% (P < .001); nonfatal myocardial infarction of 5.3, .5, 7.0, and 2.6% (P < .001); stroke of .40, .45, .90, and .90% (P = NS); and additional intervention of 3.8, 11.7, 10.3, and 2.6% (P < .001). Conclusion: In this sample, regardless of the treatment previously received patients with or without diabetes and preserved ventricular function experienced similar outcomes. However, patients with ventricular dysfunction had a worse prognosis compared with those with normal ventricular function; patients with diabetes had greater mortality than patients without diabetes.Trial registration http://www.controlled-trials.com.

AB - Background: Obesity is associated with significant physical, psychosocial and economic burden globally. In Brazil, almost 50% of the population is either overweight or obese. The prevalence of morbid obesity increased by 255% between 1975 and 2003. The current study sought to quantify the relationship between weight status and health outcomes. Methods: Data from three waves (2011, 2012, and 2015) of the Brazil National Health and Wellness Survey, an Internet-based survey administered to a demographically diverse sample of Brazilian adults, were used. Body mass index category was calculated based on self-reported height and weight and respondents were categorized into five groups (normal, overweight, obese class I, obese class II, obese class III; n = 34,254). Multivariable analyses, controlling for sociodemographic variables and health history, tested the association with body mass index group and outcomes including health status (Medical Outcomes Study Short Form 12-Item Health Survey version 2/Medical Outcomes Study Short Form 36-Item Health Survey version 2), work productivity (Work Productivity and Activity Impairment-General Health Questionnaire), and costs associated with work impairment (indirect costs), self-reported healthcare resource use and associated direct costs. Results: Overall, 53.6% of the surveyed Brazilian population reported being overweight or obese. In virtually all the analyses, increasing body mass index group was associated with significant and progressively worse outcomes. Most notable was the finding that hospitalization costs were over twice as high (R$3141.84 vs. R$1349.60) and indirect costs were nearly double (R$1656.80 vs. R$884.15) for obesity class III than for normal body mass index respondents. Conclusions: Obesity rates in Brazil are considerable and, from a patient and societal perspective, increasingly burdensome, thereby highlighting the need for stakeholders to prioritize strategies for weight management interventions. PMID- 29568333 TI - Relationship between "a body shape index (ABSI)" and body composition in obese patients with type 2 diabetes. AB - Background: Obesity is known to be related to the development of type 2 diabetes mellitus (T2D). The most commonly used anthropometric indicator (body mass index [BMI]) presents several limitations such as the lack of possibility to distinguish adipose tissue distribution. Thus, this study examines the suitability of a body shape index (ABSI) for prediction of body composition and sarcopenic obesity in obese or overweight T2D subjects. Methods: Cross-sectional study in 199 overweight/obese T2D adults. Anthropometric (BMI, ABSI) and body composition (fat mass [FM], fat-free mass [FFM], fat mass index [FMI] and fat free mass index, and the ratio FM/FFM as an index of sarcopenic obesity) data was collected, as well as metabolic parameters (glycated haemoglobin [HbA1c], mean blood glucose, fasting plasma glucose [FPG], high-density-lipoprotein cholesterol [HDL], low-density-lipoprotein cholesterol, total cholesterol, and triglycerides [TG] levels; the ratio TG/HDL was also calculated as a surrogate marker for insulin resistance). Results: ABSI was significantly associated with age and waist circumference. It showed a statistically significant correlation with BMI exclusively in women. Regarding body composition, in men, ABSI was associated with FM (%), while in women it was associated with both FM and FFM. Both males and females groups with high ABSI scores were significantly older (men: 59.3 +/- 10.8 vs 54.6 +/- 10.1, p <= 0.05; women: 65.1 +/- 9.8 vs 58.1 +/- 13.3, p <= 0.005) and showed lower FFM values (men: 62.3 +/- 9.0 vs 66.2 +/- 9.3, p <= 0.05; women: 48.7 +/- 5.6 vs 54.5 +/- 8.9, p <= 0.001) compared with low-ABSI groups. Multiple linear regression revealed that ABSI independently predict FMI and the FM/FFM ratio in women. Sarcopenic obesity was identified in 70 (36.5%) individuals according to the FM/FFM ratio. The AUROC of ABSI was 63.1% (95% CI 54.6-71.6%; p = 0.003) and an ABSI value of 0.083 m11/6 kg-2/3 was the optimal threshold in discriminating patients with sarcopenic obesity (sensitivity: 48%, specificity: 73%). Moreover, a significant association between ABSI and FPG was found in men. Conclusions: ABSI could be useful to identify visceral and sarcopenic obesity in overweight/obese adults with T2D, adding some relevant clinical information to traditional anthropometric measures. PMID- 29568334 TI - Serum uric acid and renal function in patients with type 1 diabetes: a nationwide study in Brazil. AB - Background: Diabetes nephropathy is a microvascular complication associated with high morbidity and mortality in patients with type 1 diabetes, and its pathogenesis is not fully understood. Our aim was to evaluate the association between levels of serum uric acid and renal function assessed by glomerular filtration rate (GFR) and albuminuria in patients with type 1 diabetes. Methods: This is a multicenter, cross-sectional, observational study with 1686 patients, conducted between August 2011 and August 2014 in 14 public clinics from ten Brazilian cities. Renal function was estimated by CKD-EPI (adults) and by Schwartz (adolescents). Results: We analyzed 1686 patients, aged 30.1 +/- 12.0, with 15.4 +/- 9.3 years of duration of diabetes; 55.8% were female and 54.0% were Caucasians. Serum uric acid was related to renal function, with a mean of 4.8 +/- 1.4 (in the normal renal function group) vs 5.2 +/- 2.0 (GFR >= 60 ml/min and albuminuria) vs 6.5 +/- 2.6 mg/dl (GFR < 60 ml/min). In the pooled group, multivariate analysis showed an inverse correlation between serum uric acid and GFR (r = - 0.316, p < 0.001) with a decrease of 4.11 ml/min in the GFR for every increase of 1 mg/dl in serum uric acid. Considering only patients with normal renal function (n = 1170), a decrease of 2.04 ml/min in the GFR for every increase of 1 mg/dl in Serum uric acid was noted using multivariate analysis. Conclusions: Patients with higher levels of serum uric acid have worse renal function, independently of HbA1c or duration of diabetes, which persisted even in patients with normal renal function. Further prospective studies are necessary to establish if patients with higher serum uric acid may have an elevated risk for developing chronic kidney disease. PMID- 29568335 TI - Paper Spray Mass Spectrometry for High-Throughput Quantification of Nicotine and Cotinine. AB - The rapid release of new tobacco products requires high-throughput quantitative methods to support tobacco research. Sample preparation for LC-MS and GC-MS is time consuming and limits throughput. Paper spray tandem mass spectrometry (PS MS/MS) is proposed and validated as a simple and rapid method for quantification of nicotine and cotinine in complex matrices to support tobacco-related research. Air liquid interface (ALI) human tracheobronchial epithelial cell (HTBEC) cultures were exposed to tobacco smoke using a Vitrocell VC-10 smoking machine. Apical culture washes (phosphate buffered saline, PBS) and basolateral media were analyzed with the PS-MS/MS method. GC-MS/MS was used as a comparative quantitative technique. The PS-MS/MS approach allowed for direct spotting of samples on the paper substrate, whereas the GC-MS/MS method required additional sample preparation in the form of solvent-solvent extraction. Limits of quantitation (LOQs) were higher with the PS-MS/MS approach than GC-MS/MS, but still below the relevant concentrations found in HTBEC smoke exposure experiments as well as most clinical applications. PS-MS/MS is readily achieved on mass spectrometers that include atmospheric pressure inlets, and allows for convenient quantification from complex matrices that would otherwise require additional sample preparation and chromatographic separation. PMID- 29568336 TI - Testing the single-pass VOC removal efficiency of an active green wall using methyl ethyl ketone (MEK). AB - In recent years, research into the efficacy of indoor air biofiltration mechanisms, notably living green walls, has become more prevalent. Whilst green walls are often utilised within the built environment for their biophilic effects, there is little evidence demonstrating the efficacy of active green wall biofiltration for the removal of volatile organic compounds (VOCs) at concentrations found within an interior environment. The current work describes a novel approach to quantifying the VOC removal effectiveness by an active living green wall, which uses a mechanical system to force air through the substrate and plant foliage. After developing a single-pass efficiency protocol to understand the immediate effects of the system, the active green wall was installed into a 30-m3 chamber representative of a single room and presented with the contaminant 2-butanone (methyl ethyl ketone; MEK), a VOC commonly found in interior environments through its use in textile and plastic manufacture. Chamber inlet levels of MEK remained steady at 33.91 +/- 0.541 ppbv. Utilising a forced-air system to draw the contaminated air through a green wall based on a soil-less growing medium containing activated carbon, the combined effects of substrate media and botanical component within the biofiltration system showed statistically significant VOC reduction, averaging 57% single-pass removal efficiency over multiple test procedures. These results indicate a high level of VOC removal efficiency for the active green wall biofilter tested and provide evidence that active biofiltration may aid in reducing exposure to VOCs in the indoor environment. PMID- 29568337 TI - Evaluation of daily time spent in transportation and traffic-influenced microenvironments by urban Canadians. AB - Exposure to traffic and traffic-related air pollution is associated with a wide array of health effects. Time spent in a vehicle, in active transportation, along roadsides, and in close proximity to traffic can substantially contribute to daily exposure to air pollutants. For this study, we evaluated daily time spent in transportation and traffic-influenced microenvironments by urban Canadians using the Canadian Human Activity Pattern Survey (CHAPS) 2 results. Approximately 4-7% of daily time was spent in on- or near-road locations, mainly associated with being in a vehicle and smaller contributions from active transportation. Indoor microenvironments can be impacted by traffic emissions, especially when located near major roadways. Over 60% of the target population reported living within one block of a roadway with moderate to heavy traffic, which was variable with income level and city, and confirmed based on elevated NO2 exposure estimated using land use regression. Furthermore, over 55% of the target population <= 18 years reported attending a school or daycare in close proximity to moderate to heavy traffic, and little variation was observed based on income or city. The results underline the importance of traffic emissions as a major source of exposure in Canadian urban centers, given the time spent in traffic influenced microenvironments. PMID- 29568338 TI - Daily land use regression estimated woodsmoke and traffic pollution concentrations and the triggering of ST-elevation myocardial infarction: a case crossover study. AB - Prior work has reported acute associations between ST-elevation myocardial infarction (STEMI) and short-term increases in airborne particulate matter. Subsequently, the association between STEMI and hourly measures of Delta-C (marker of woodsmoke) and black carbon (marker of traffic pollution) measured at a central site in Rochester, NY, were examined, but no association was found. Therefore, land use regression estimates of Delta-C and black carbon concentrations at each patient's residence were developed for 246 STEMI patients treated at the University of Rochester Medical Center during the winters of 2008 2012. Using case-crossover methods, the rate of STEMI associated with increased Delta-C and BC concentration on the same and previous 3 days was estimated after adjusting for 3-day mean temperature and relative humidity. Non-statistically significant increased rates of STEMI associated with interquartile range increases in concentrations of BC in the previous 2 days (1.10 MUg/m3; OR = 1.12; 95% CI 0.93, 1.35) and Delta-C in the previous 3 days (0.43 MUg/m3; OR = 1.16; 95% CI 0.96, 1.40) were found. Significantly increased rates of STEMI associated with interquartile range increases in concentrations of BC (1.23 MUg/m3; OR = 1.04; 95% CI = 0.87, 1.24) or Delta-C (0.40 MUg/m3; OR = 0.94; 95% CI = 0.85, 1.09) on the same day were not observed likely due, in part, to temporal misalignment. Therefore, sophisticated spatial-temporal models will be needed to minimize exposure error and bias by better predicting concentrations at individual locations for individual hours, especially for outcomes with short term responses to air pollution (< 24 h). PMID- 29568340 TI - General Considerations for Improving Photovoltage in Metal-Insulator Semiconductor Photoanodes. AB - Metal-insulator-semiconductor (MIS) photoelectrodes offer a simple alternative to the traditional semiconductor-liquid junction and the conventional p-n junction electrode. Highly efficient MIS photoanodes require interfacial surface passivating oxides and high workfunction metals to produce a high photovoltage. Herein, we investigate and analyze the effect of interfacial oxides and metal workfunctions on the barrier height and the photovoltage of a c-Si photoanode. We use two metal components in a bimetal contact configuration and observe the modulation of the effective barrier height and the resulting photovoltage as a function of the secondary outer metal. The photovoltage shows a strong linear dependence by increasing the inner metal workfunction, with the highest photovoltage achieved by a MIS photoanode using a platinum inner metal. We also found that coupling a thin aluminium oxide with an interfacial silicon oxide and controlling the oxide thickness can significantly improve the photovoltage of an MIS junction photoanode. PMID- 29568341 TI - Structural Characterization of Electron Donors in Ziegler-Natta Catalysts. AB - Ziegler-Natta catalysis is a very important industrial process for the production of polyolefins. However, the catalysts are not well-understood at the molecular level. Yet, atomic-scale structural information is of pivotal importance for rational catalyst development. We applied a solid-state NMR/density functional theory tandem approach to gain detailed insight into the interactions between the catalysts' support, MgCl2, and organic electron donors. Because of the heterogeneity of the samples, large line widths are observed in the carbon spectra. Despite this, good agreement between experimental and computational values was reached, and this shows that 1,3-diether based donors coordinate at (110) surface sites, while phthalates are less selective and coordinate at both (104) and (110) surface sites. PMID- 29568339 TI - Repetitive Transcranial Magnetic Stimulation, Cognition, and Multiple Sclerosis: An Overview. AB - Multiple sclerosis (MS) affects cognition in the majority of patients. A major aspect of the disease is brain volume loss (BVL), present in all phases and types (relapsing and progressive) of the disease and linked to both motor and cognitive disabilities. Due to the lack of effective pharmacological treatments for cognition, cognitive rehabilitation and other nonpharmacological interventions such as repetitive transcranial magnetic stimulation (rTMS) have recently emerged and their potential role in functional connectivity is studied. With recently developed advanced neuroimaging and neurophysiological techniques, changes related to alterations of the brain's functional connectivity can be detected. In this overview, we focus on the brain's functional reorganization in MS, theoretical and practical aspects of rTMS utilization in humans, and its potential therapeutic role in treating cognitively impaired MS patients. PMID- 29568342 TI - Smoking, environmental tobacco smoke and occupational irritants increase the risk of chronic rhinitis. AB - Background: Allergic and non-allergic rhinitis cause a lot of symptoms in everyday life. To decrease the burden more information of the preventable risk factors is needed. We assessed prevalence and risk factors for chronic nasal symptoms, exploring the effects of smoking, environmental tobacco smoke, exposure to occupational irritants, and their combinations. Methods: In 2016, a postal survey was conducted among a random population sample of 8000 adults in Helsinki, Finland with a 50.5% response rate. Results: Smoking was associated with a significant increase in occurrence of chronic rhinitis (longstanding nasal congestion or runny nose), but not with self-reported or physician diagnosed allergic rhinitis. The highest prevalence estimates of nasal symptoms, 55.1% for chronic rhinitis, 49.1% for nasal congestion, and 40.7% for runny nose, were found among smokers with occupational exposure to gases, fumes or dusts.Besides active smoking, also exposure to environmental tobacco smoke combined with occupational exposure increased the risk of nasal symptoms. Conclusions: Smoking, environmental tobacco smoke, and occupational irritants are significant risk factors for nasal symptoms with an additive pattern. The findings suggest that these factors should be systematically inquired in patients with nasal symptoms for appropriate preventive measures. (192 words). PMID- 29568343 TI - The SRC-family tyrosine kinase HCK shapes the landscape of SKAP2 interactome. AB - The SRC Kinase Adaptor Phosphoprotein 2 (SKAP2) is a broadly expressed adaptor associated with the control of actin-polymerization, cell migration, and oncogenesis. After activation of different receptors at the cell surface, this dimeric protein serves as a platform for assembling other adaptors such as FYB and some SRC family kinase members, although these mechanisms are still poorly understood. The goal of this study is to map the SKAP2 interactome and characterize which domains or binding motifs are involved in these interactions. This is a prerequisite to finely analyze how these pathways are integrated in the cell machinery and to study their role in cancer and other human diseases when this network of interactions is perturbed. In this work, the domain and the binding motif of fourteen proteins interacting with SKAP2 were precisely defined and a new interactor, FAM102A was discovered. Herein, a fine-tuning between the binding of SRC kinases and their activation was identified. This last process, which depends on SKAP2 dimerization, indirectly affects the binding of FYB protein. Analysis of conformational changes associated with activation/inhibition of SRC family members, presently limited to their effect on kinase activity, is extended to their interactive network, which paves the way for therapeutic development. PMID- 29568344 TI - Correlation and agreement between eplet mismatches calculated using serological, low-intermediate and high resolution molecular human leukocyte antigen typing methods. AB - Structural human leukocyte antigen (HLA) matching at the eplet level can be identified by HLAMatchmaker, which requires the entry of four-digit alleles. The aim of this study was to evaluate the agreement between eplet mismatches calculated by serological and two-digit typing methods compared to high resolution four-digit typing. In a cohort of 264 donor/recipient pairs, the evaluation of measurement error was assessed using intra-class correlation to confirm the absolute agreement between the number of eplet mismatches at class I (HLA-A, -B, C) and II loci (HLA-DQ and -DR) calculated using serological or two digit molecular typing compared to four-digit molecular typing methods. The proportion of donor/recipient pairs with a difference of >5 eplet mismatches between the HLA typing methods was also determined. Intra-class correlation coefficients between serological and four-digit molecular typing methods were 0.969 (95% confidence intervals [95% CI] 0.960-0.975) and 0.926 (95% CI 0.899 0.944), respectively; and 0.995 (95% CI 0.994-0.996) and 0.993 (95% CI 0.991 0.995), respectively between two-digit and four-digit molecular typing methods. The proportion of donor/recipient pairs with a difference of >5 eplet mismatches at class I and II loci was 4% and 16% for serological versus four-digit molecular typing methods, and 0% and 2% for two-digit versus four-digit molecular typing methods, respectively. In this small predominantly Caucasian population, compared with serology, there is a high level of agreement in the number of eplet mismatches calculated using two-compared to four-digit molecular HLA-typing methods, suggesting that two-digit typing may be sufficient in determining eplet mismatch load in kidney transplantation. PMID- 29568345 TI - IL-21 modulates memory and exhaustion phenotype of T-cells in a fatty acid oxidation-dependent manner. AB - T-cell-based therapies represent a promising strategy for cancer treatment. In this context, cytokines are discussed as a bona fide instrument for fine-tuning T cell biology. One promising candidate is the pleiotropic interleukin-21 (IL-21) with only little being known regarding its direct effects on human T-cells. Thus, we sought out to characterize the impact of IL-21 on T-cell metabolism, fitness, and differentiation. Culturing T-cells in presence of IL-21 elicited a metabolic skewing away from aerobic glycolysis towards fatty acid oxidation (FAO). These changes of the metabolic framework were paralleled by increased mitochondrial fitness and biogenesis. However, oxidative stress levels were not increased but rather decreased. Furthermore, elevated FAO and mitochondrial biomass together with enhanced antioxidative properties are linked to formation of longer lasting memory responses and less PD-1 expression. We similarly observed an IL-21 triggered induction of central memory-like T-cells and reduced levels of PD-1 on the cell surface. Taken together, IL-21 shifts T-cells towards an immunometabolic phenotype that has been associated with increased survivability and enhanced anti tumor efficacy. In addition, our data reveals a novel interconnection between fatty acid metabolism and immune function regulated by IL 21. PMID- 29568346 TI - Validating and enabling phosphoglycerate dehydrogenase (PHGDH) as a target for fragment-based drug discovery in PHGDH-amplified breast cancer. AB - 3-Phosphoglycerate dehydrogenase (PHGDH) has recently been identified as an attractive target in cancer therapy as it links upregulated glycolytic flux to increased biomass production in cancer cells. PHGDH catalyses the first step in the serine synthesis pathway and thus diverts glycolytic flux into serine synthesis. We have used siRNA-mediated suppression of PHGDH expression to show that PHGDH is a potential therapeutic target in PHGDH-amplified breast cancer. Knockdown caused reduced proliferation in the PHGDH-amplified cell line MDA-MB 468, whereas breast cancer cells with low PHGDH expression or with elevated PHGDH expression in the absence of genomic amplification were not affected. As a first step towards design of a chemical probe for PHGDH, we report a fragment-based drug discovery approach for the identification of PHGDH inhibitors. We designed a truncated PHGDH construct that gave crystals which diffracted to high resolution, and could be used for fragment soaking. 15 fragments stabilising PHGDH were identified using a thermal shift assay and validated by X-ray crystallography and ITC competition experiments to exhibit 1.5-26.2 mM affinity for PHGDH. A structure-guided fragment growing approach was applied to the PHGDH binders from the initial screen, yielding greater understanding of the binding site and suggesting routes to achieve higher affinity NAD-competitive inhibitors. PMID- 29568347 TI - Targeting DYRK1B suppresses the proliferation and migration of liposarcoma cells. AB - Liposarcoma is a common subtype of soft tissue sarcoma and accounts for 20% of all sarcomas. Conventional chemotherapeutic agents have limited efficacy in liposarcoma patients. Expression and activation of serine/threonine-protein kinase dual-specificity tyrosine-(Y)-phosphorylation regulated kinase 1B (DYRK1B) is associated with growth and survival of many types of cancer cells. However, the role of DYRK1B in liposarcoma remains unknown. In this study, we investigated the functional and therapeutic relevance of DYRK1B in liposarcoma. Tissue microarray and immunohistochemistry analysis showed that higher expression levels of DYRK1B correlated with a worse prognosis. RNA interference-mediated knockdown of DYRK1B or targeting DYRK1B with the kinase inhibitor AZ191 inhibited liposarcoma cell growth, decreased cell motility, and induced apoptosis. Moreover, combined AZ191 with doxorubicin demonstrated an increased anti-cancer effect on liposarcoma cells. These findings suggest that DYRK1B is critical for the growth of liposarcoma cells. Targeting DYRK1B provides a new rationale for treatment of liposarcoma. PMID- 29568348 TI - Phthalate exposure promotes chemotherapeutic drug resistance in colon cancer cells. AB - Phthalates are widely used as plasticizers. Humans can be exposed to phthalates through ingestion, inhalation, or treatments that release di(2-ethylhexyl) phthalate (DEHP) and its metabolite, mono(2-ehylhexyl) phthalate (MEHP), into the body from polyvinyl chloride-based medical devices. Phthalate exposure may induce reproductive toxicity, liver damage, and carcinogenesis in humans. This study found that colon cancer cells exposed to DEHP or MEHP exhibited increased cell viability and increased levels of P-glycoprotein, CD133, Bcl-2, Akt, ERK, GSK3beta, and beta-catenin when treated with oxaliplatin or irinotecan, as compared to control. The P-glycoprotein inhibitor, tariquidar, which blocks drug efflux, reduced the viability of DEHP- or MEHP-treated, anti-cancer drug challenged cells. DEHP or MEHP treatment also induced colon cancer cell migration and epithelial-mesenchymal transformation. Elevated stemness-related protein levels (beta-catenin, Oct4, Sox2, and Nanog) and increased cell sphere sizes indicated that DEHP- or MEHP-treated cells were capable of self-renewal. We also found that serum DEHP concentrations were positively correlated with cancer recurrence. These results suggest phthalate exposure enhances colon cancer cell metastasis and chemotherapeutic drug resistance by increasing cancer cell stemness, and that P-glycoprotein inhibitors might improve outcomes for advanced or drug-resistant colon cancer patients. PMID- 29568349 TI - Exploring the pathogenesis of canine epilepsy using a systems genetics method and implications for anti-epilepsy drug discovery. AB - Epilepsy is a common neurological disorder in domestic dogs. However, its complex mechanism involves multiple genetic and environmental factors that make it challenging to identify the real pathogenic factors contributing to epilepsy, particularly for idiopathic epilepsy. Conventional genome-wide association studies (GWASs) can detect various genes associated with epilepsy, although they primarily detect the effects of single-site mutations in epilepsy while ignoring their interactions. In this study, we used a systems genetics method combining both GWAS and gene interactions and obtained 26 significantly mutated subnetworks. Among these subnetworks, seven genes were reported to be involved in neurological disorders. Combined with gene ontology enrichment analysis, we focused on 4 subnetworks that included traditional GWAS-neglected genes. Moreover, we performed a drug enrichment analysis for each subnetwork and identified significantly enriched candidate anti-epilepsy drugs using a hypergeometric test. We discovered 22 potential drug combinations that induced possible synergistic effects for epilepsy treatment, and one of these drug combinations has been confirmed in the Drug Combination database (DCDB) to have beneficial anti-epileptic effects. The method proposed in this study provides deep insight into the pathogenesis of canine epilepsy and implications for anti epilepsy drug discovery. PMID- 29568350 TI - EIF3C-enhanced exosome secretion promotes angiogenesis and tumorigenesis of human hepatocellular carcinoma. AB - Targeting tumor angiogenesis is a common strategy against human hepatocellular carcinoma (HCC). However, identification of molecular targets as biomarker for elevating therapeutic efficacy is critical to prolong HCC patient survival. Here, we showed that EIF3C (eukaryotic translation initiation factor 3 subunit C) is upregulated during HCC tumor progression and associated with poor patient survival. Expression of EIF3C did not alter proliferation and expression of other tumor progressive genes such as HIF1A, TGFbeta1 and VEGF, but reduced cell migration in HCC cells. Nevertheless, expression of EIF3C in HCC cells significantly increase secretion of extracellular exosomes confirmed by increased exosomes labelling by PKH26 fluorescent dye, vesicles in exosome size detected by electronic microscopy and nanoparticle tracking analysis, and expression of divergent exosome markers. The EIF3C-increased exosomes were oncogenic to potentiate tumor angiogenesis via tube formation of HUVEC cells and growth of vessels by plugs assays on nude mice. Subcutaneous inoculation of EIF3C-exosomes mixed with Huh7 HCC cells not only promoted growth of vessels but also increased expression of EIF3C in tumors. Conversely, treatment of exosome inhibitor GW4869 reversed aforementioned oncogenic assays. We identified EIF3C activated expression of S100A11 involved in EIF3C-exosome increased tube formation in angiogenesis. Simultaneous high expression of EIF3C and S100A11 in human HCC tumors for RNA level in TCGA and protein level by IHC are associated with poor survival of HCC patients. Collectively, our results demonstrated that EIF3C overexpression is a potential target of angiogenesis for treatment with exosome inhibitor or S100A11 reduction to suppress HCC angiogenesis and tumorigenesis. PMID- 29568351 TI - Targeting of embryonic annexin A2 expressed on ovarian and breast cancer by the novel monoclonal antibody 2448. AB - Monoclonal antibodies (mAbs) play an increasingly important role in cancer therapy. To address the wide heterogeneity of the disease, the identification of novel antigen targets and the development of mAbs against them are needed. Our lab previously generated a panel of mAbs against human embryonic stem cells (hESC) using a whole cell immunization approach in mice. These mAbs can potentially target oncofetal antigens and be repurposed for antibody or antibody drug conjugate (ADC) therapy. From this panel, the novel IgG1 2448 was found to bind surface antigens on hESC and multiple cancer cell lines. Here, we show 2448 targets a unique glycan epitope on annexin A2 (ANXA2) and can potentially monitor the Epithelial-Mesenchymal Transition (EMT) in ovarian and breast cancer. To evaluate 2448 as a potential drug, 2448 was engineered and expressed as a chimeric IgG1. Chimeric 2448 (ch2448) demonstrated efficient and specific killing when conjugated to cytotoxic payloads as an ADC. In addition, ch2448 elicited potent antibody-dependent cell-mediated cytotoxicity (ADCC) activity in vitro and in vivo. Further engineering of ch2448 to remove fucose in the Fc domain enhanced ADCC. Overall, these findings indicate that embryonic ANXA2 is an attractive target and suggest that ch2448 is a promising candidate for further therapeutic development. PMID- 29568352 TI - The single-nucleotide polymorphisms in CHD5 affect the prognosis of patients with hepatocellular carcinoma. AB - Previous studies showed that the low expressions of chromodomain-helicase-DNA binding protein 5 (CHD5) were intensively associated with deteriorative biologic and clinical characteristics as well as outcomes in many tumors. The aim of this study is to determine whether CHD5 single nucleotide polymorphisms (SNPs) contribute to the prognosis of hepatocellular carcima (HCC). The SNPs were selected according to their linkage disequilibrium (LD) in the targeted next generation sequencing (NGS) and then genotyped with TaqMan probers. We revealed a rare haplotype AG in CHD5 (SNPs: rs12564469-rs9434711) was markedly associated with HCC prognosis. The univariate and multivariate regression analyses revealed the patients with worse overall survival time were those with tumor metastasis and haplotype AG, as well as cirrhosis, poor differentiation and IV-TNM stage. Based on the available public databases, we discovered the significant association between haplotype AG and CHD5 mRNA expressions only existed in Chinese. These data proposed that the potentially genetic haplotype might functionally contribute to HCC prognosis and CHD5 mRNA expressions. PMID- 29568353 TI - Reprogrammed lipid metabolism in bladder cancer with cisplatin resistance. AB - Due to its tendency to recur and acquire chemoresistance quickly, bladder cancer (BC) remains to be an elusive and difficult disease. Patients with recurrent and chemoresistant BC have an extremely poor prognosis. One possible approach that may provide insightful and valuable information regarding resistance mechanisms is looking into the lipid metabolism of BC cells. Metabolism of lipids is essential for cancer cells and is associated with the regulation of a variety of key cellular processes and functions. This study conducted a comparative lipidomic profiling of two isogenic human T24 bladder cancer cell lines, one of which is clinically characterized as cisplatin-sensitive (T24S) and the other as cisplatin-resistant (T24R). Immunohistochemistry analysis revealed that expression of cytosolic acetyl-CoA synthetase 2 (ACSS2) is positively correlated with aggressive BC. Ultra performance liquid chromatography-mass spectrometry (UPLC-MS) analysis profiled a total of 1,864 lipids and levels of differentially expressed lipids suspected of being associated with cisplatin resistance were determined. In addition, we found that ACSS2 inhibition greatly perturbed levels of metabolites, including CE(18:1), CE(22:6), TG(49:1), and TG(53:2). This study broadens our current knowledge on the links between cisplatin resistance and lipid metabolism in aggressive BC and suggests potential biomarkers for identifying higher-risk patients.

AB - Telomerase is a unique cellular reverse transcriptase (RT) essential for maintaining telomere stability and required for the unlimited proliferation of cancer cells. The limiting determinant of telomerase activity is the catalytic component TERT, and TERT expression is closely correlated with telomerase activity and cancer initiation and disease progression. For this reason the regulation of TERT levels in the cell is of great importance. microRNAs (miRs) function as an additional regulatory level in cells, crucial for defining expression boundaries, proper cell fate decisions, cell cycle control, genome integrity, cell death and metastasis. We performed an anti-miR library screen to identity novel miRs, which participate in the control of telomerase. We identified the tumor suppressor miR (miR-128) as a novel endogenous telomerase inhibitor and determined that miR-128 significantly reduces the mRNA and protein levels of Tert in a panel of cancer cell lines. We further evaluated the mechanism by which miR-128 regulates TERT and demonstrated that miR-128 interacts directly with the coding sequence of TERT mRNA in both HeLa cells and teratoma cells. Interestingly, the functional miR-128 binding site in TERT mRNA, is conserved between TERT and the other cellular reverse transcriptase encoded by Long Interspersed Elements-1 (LINE-1 or L1), which can also contribute to the oncogenic phenotype of cancer. This finding supports the novel idea that miRs may function in parallel pathways to inhibit tumorigenesis, by regulating a group of enzymes (such as RT) by targeting conserved binding sites in the coding region of both enzymes. PMID- 29568355 TI - Mitochondrial fission as a driver of stemness in tumor cells: mDIVI1 inhibits mitochondrial function, cell migration and cancer stem cell (CSC) signalling. AB - Mitochondria are dynamic organelles frequently undergoing fission and fusion events to maintain their integrity, bioenergetics and spatial distribution, which is fundamental to the processes of cell survival. Disruption in mitochondrial dynamics plays a role in cancer. Therefore, proteins involved in regulating mitochondrial dynamics are potential targets for treatment. mDIVI1 is an inhibitor of the mitochondrial fission protein DRP1, which induces i) mitochondrial oxidative stress and ii) effectively reduces mitochondrial metabolism. We show here that mDIVI1 is able to inhibit 3D tumorsphere forming capacity, cell migration and stemness-related signalling in breast cancer cells, indicating that mDIVI1 can potentially be used for the therapeutic elimination of cancer stem cells (CSCs). PMID- 29568356 TI - Neutrophil extracellular traps promote lipopolysaccharide-induced airway inflammation and mucus hypersecretion in mice. AB - Bacterial lipopolysaccharide (LPS) contributes to airway inflammation and mucus hypersecretion in chronic airway inflammatory diseases, such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF). Neutrophil extracellular traps (NETs) are extracellular meshworks composed of DNA fibers and antimicrobial proteins. Although NET formation has been detected in COPD and CF patients, how NETs contribute to these diseases is poorly understood. This study was performed to clarify the effects and mechanisms of action of NETs in airway inflammation and mucus hypersecretion. We created a murine model of LPS-induced airway inflammation and mucus hypersecretion, and found that LPS-induced NET formation was degraded by aerosolized DNase I treatment in mice. Degradation of NETs by aerosolized DNase I reduced LPS-induced airway inflammation and mucus hypersecretion in mice, this reduction correlated with suppression of TLR4/NF kappaB signaling pathway. More importantly, NETs promoted LPS-induced production of IL-1beta, IL-6 and TNF-alpha in macrophages. These results suggest NET degradation using aerosolized DNase I is a potential new therapeutic strategy for treating COPD and CF. PMID- 29568357 TI - Deficiency of protein-L-isoaspartate (D-aspartate) O-methyl-transferase expression under endoplasmic reticulum stress promotes epithelial mesenchymal transition in lung adenocarcinoma. AB - A prognostic association between the novel chaperone protein-L-isoaspartate (D aspartate) O-methyltransferase (PIMT) and lung adenocarcinoma has recently been reported. Here, we evaluated the functional roles of PIMT in the progression of lung adenocarcinoma. PIMT expression was detectable in 6 lung adenocarcinoma cell lines: A549, H441, H460, H1650, Calu 1, and Calu 6 cell lines. In A549 and H441 cells, knockdown by PIMT using silencing RNA of PIMT (si-PIMT) and/or small hairpin-RNA (sh-PIMT) induced a decrease in the expression of E-cadherin with an increase in vimentin expression, indicating that the epithelial to mesenchymal transition (EMT) was induced. Cell mobility, including migration and invasion capability, was increased in sh-PIMT A549 stable and si-PIMT H441 cells compared to in control cells. Endoplasmic reticulum (ER) stress, such as Thapsigargin (Tg) stress and hypoxia, induced EMT in A549 cells but not in other cell types, with an increase in GRP78 expression, whereas overexpression of PIMT reduced the EMT and cell invasion under stress conditions. The expression of hypoxia inducible factor-1 alpha (HIF1alpha) and Twist increased in sh-PIMT A549 and si-PIMT H441 cells, and Tg stress increased HIF1alpha expression levels in A549 cells in a dose-dependent manner. Moreover, LW6, an HIF1alpha inhibitor, reduced EMT, cancer invasion, and the levels of Twist in sh-PIMT A549 cells. Our results indicate that deficiency of supplemental PIMT expression under ER stress facilitates EMT and cell invasion in some cell types of lung adenocarcinoma. PMID- 29568358 TI - Systemic administration of a TLR7 agonist attenuates regulatory T cells by dendritic cell modification and overcomes resistance to PD-L1 blockade therapy. AB - Research on immune checkpoint blockade therapy has made great progress in cancer immunotherapy, but the number of patients who benefit from this therapy remains limited. In this study, we examined the effects of monotherapy with systemic low dose resiquimod, a synthesized TLR7 agonist, and examined its combined effects with PD-L1 blockade in two PD-L1 blockade-resistant tumor models (SCCVII and Colon 26). Resiquimod monotherapy in SCCVII tumors, representing impaired CD8+ T cell function and accelerated regulatory T cells (Tregs) within the tumors, efficiently reduced tumor growth with more recruitment of CD8+ T cells and a reduction of Treg. The results of resiquimod monotherapy in Colon 26, representing impaired Treg recruitment, were inferior to that in SCCVII. Combined resiquimod treatment with PD-L1 blockade exerted clear additional effects, as it was associated with reduced tumor size, attenuation of Tregs, and an increased ratio of CD8+ T cells/Tregs in both tumors. Systemic administration of low-dose resiquimod induced a transient and rapid activation of plasmacytoid and conventional dendritic cells, resulting in enhanced priming of T cells in regional lymph nodes. Experiments with more limited doses of resiquimod that did not yield beneficial effects after single treatment, showed additional effects to PD-L1 blockade and comparable antitumor effects when the frequency of anti-PD-L1 therapy was decreased. Our results suggest that systemic administration of low dose resiquimod is useful as a companion drug to PD-1/PD-L1 blockade therapy. PMID- 29568359 TI - CD151 promotes cell metastasis via activating TGF-beta1/Smad signaling in renal cell carcinoma. AB - Tetraspanin CD151 has been identified as a tumor promoter, which is upregulated in various malignant cell types. However, the function of CD151 and its underlying mechanism in renal cell carcinoma is still unknown. In this study, we detected the expression of CD151 in RCC cells and tissues and explored its regulatory mechanism. We found that CD151 was upregulated in renal cell carcinoma tissues and cells and its expression was significantly associated with tumor stage (p=0.019) and survival (p=0.001) by analyzing tissue microarrays. After silencing of CD151 via lentivirus vector in Caki-1 and Caki-2 cells, reduced ability of migration and invasion were detected with downregulation of CD151. The opposite results were observed in cells with CD151 overexpression. Furthermore, western blotting was performed to investigate the influence of CD151 on epithelial-to-mesenchymal transition, matrix metalloproteinase 9 and TGF beta1/Smad signaling pathway in RCC. Subsequently, upregulating the protein level of transforming growth factor-beta1 in cells with silencing of CD151 could rescue the malignant behaviors inhibited, which indicated that CD151 may play its promoting role in RCC partially by stimulating the expression of TGF-beta1. Conclusively, CD151 might exhibit a prominent role in migration and invasion of RCC cells via activating TGF-beta1/Smad signaling pathway. PMID- 29568360 TI - Methotrexate sensitizes drug-resistant metastatic melanoma cells to BRAF V600E inhibitors dabrafenib and encorafenib. AB - Acquired resistance of metastatic melanoma (MM) tumors to BRAF V600E inhibitors (BRAFi's) is commonplace in the clinic. Habitual relapse of patients contributes to <20% 5-year survival rates in MM. We previously identified serine synthesis as a critical detrminant of late-stage cancer cell resistance to BRAFi's. Pre treatment with DNA damaging agent gemcitabine (a nucleoside analog) re-sensitized drug-resistant cancer cells to BRAFi's dabrafenib and vemurafenib. Importantly, the combination treatments were effective against BRAF wild type cancer cells potentially expanding the clinical reach of BRAFi's. In this study, we identify the antifolate methotrexate (MTX) as a sensitizer of acquired- and intrinsically resistant MM cells to BRAFi's dabrafenib and encorafenib. We identify a novel, positive correlation between dabrafenib treatments and repair delay of MTX induced single-strand DNA (ssDNA) breaks. Cells arrest in G1 phase following simultaneous MTX + dabrafenib treatments and eventually die via apoptosis. Importantly, we identify RAS codon 12 activating mutations as prognostic markers for MTX + BRAFi treatment efficacy. We describe a method of killing drug resistant MM cells that if translated has the potential to improve MM patient survival. PMID- 29568361 TI - Colorectal cancer cells require glycogen synthase kinase-3beta for sustaining mitosis via translocated promoter region (TPR)-dynein interaction. AB - Glycogen synthase kinase (GSK) 3beta, which mediates fundamental cellular signaling pathways, has emerged as a potential therapeutic target for many types of cancer including colorectal cancer (CRC). During mitosis, GSK3beta localizes in mitotic spindles and centrosomes, however its function is largely unknown. We previously demonstrated that translocated promoter region (TPR, a nuclear pore component) and dynein (a molecular motor) cooperatively contribute to mitotic spindle formation. Such knowledge encouraged us to investigate putative functional interactions among GSK3beta, TPR, and dynein in the mitotic machinery of CRC cells. Here, we show that inhibition of GSK3beta attenuated proliferation, induced cell cycle arrest at G2/M phase, and increased apoptosis of CRC cells. Morphologically, GSK3beta inhibition disrupted chromosome segregation, mitotic spindle assembly, and centrosome maturation during mitosis, ultimately resulting in mitotic cell death. These changes in CRC cells were associated with decreased expression of TPR and dynein, as well as disruption of their functional colocalization with GSK3beta in mitotic spindles and centrosomes. Clinically, we showed that TPR expression was increased in CRC databases and primary tumors of CRC patients. Furthermore, TPR expression in SW480 cells xenografted into mice was reduced following treatment with GSK3beta inhibitors. Together, these results indicate that GSK3beta sustains steady mitotic processes for proliferation of CRC cells via interaction with TPR and dynein, thereby suggesting that the therapeutic effect of GSK3beta inhibition depends on induction of mitotic catastrophe in CRC cells. PMID- 29568362 TI - The metal-nonoate Ni(SalPipNONO) inhibits in vitro tumor growth, invasiveness and angiogenesis. AB - Nitric oxide (NO) exerts conflicting effect on tumor growth and progression, depending on its concentration. We aimed to characterize the anti-cancer activity of a new NO donor, Ni(SalPipNONO) belonging to the class of metal-nonoates, in epithelial derived tumor cells, finally exploring its antiangiogenic properties. Tumor epithelial cells were screened to evaluate the cytotoxic effect of Ni(SalPipNONO), which was able to inhibit cell proliferation in a dose dependent manner, being more effective than the commercial DETA/NO. The human lung carcinoma cells A549 were chosen as model to study the anti-cancer mechanisms exerted by the compound. In these cells, Ni(SalPipNONO) inhibited clonogenicity and cell invasion, while promoting apoptosis. The antitumor activity was partly due to NO-cGMP dependent pathway, contributing to reduced cell number and apoptosis, and partly to the salicylaldehyde moiety and reactive oxygen species (ROS) activated ERK1/2 signaling converging on p53 dependent caspase-3 cleavage. An additional contribution by downstream cycloxygenase-2 (COX-2) derived cyclopentenones may explain the tumor inhibitory activities. As NO has been described to affect tumor angiogenesis, we checked this activity both on tumor and endothelial cell co-cultures and in Matrigel in vivo assay. Our data document that Ni(SalPipNONO) was able to both reduce angiogenic factor expression by tumor cells acting on hypoxia inducible factor-1alpha (HIF-1 alpha) level, and endothelial cell functions related to angiogenesis. Collectively, these data confirm the potential use of NO donors and in particular Ni(SalPipNONO) acting through multiple mechanisms, as an agent to be further developed to be used alone or in combination with conventional therapy. PMID- 29568363 TI - Targeting angiogenesis in multiple myeloma by the VEGF and HGF blocking DARPin(r) protein MP0250: a preclinical study. AB - The investigational drug MP0250 is a multi-specific DARPin(r) molecule that simultaneously binds and neutralizes VEGF and HGF with high specificity and affinity. Here we studied the antiangiogenic effects of the MP0250 in multiple myeloma (MM). In endothelial cells (EC) isolated from bone marrow (BM) of MM patients (MMEC) MP0250 reduces VEGFR2 and cMet phosphorylation and affects their downstream signaling cascades. MP0250 influences the secretory profile of MMEC and inhibits their in vitro angiogenic activities (spontaneous and chemotactic migration, adhesion, spreading and capillarogenesis). Compared to anti-VEGF or anti-HGF neutralizing mAbs, MP0250 strongly reduces capillary network formation and vessel-sprouting in a Matrigel angiogenesis assay. MP0250 potentiates the effect of bortezomib in the same in vitro setting. It significantly reduces the number of newly formed vessels in the choriollantoic membrane assay (CAM) and the Matrigel plug assay. In the syngeneic 5T33MM tumor model, MP0250 decreases the microvessel density (MVD) and the combination MP0250/bortezomib lowers the percentage of idiotype positive cells and the serum levels of M-protein. Overall results define MP0250 as a strong antiangiogenic agent with potential as a novel combination drug for treatment of MM patients. PMID- 29568364 TI - Efficacy of different spinal nerve roots for neuromodulation of micturition reflex in rats. AB - Electrical stimulation of peripheral nerves controlling the bladder is an alternative, nondestructive medical treatment for urinary incontinence and retention. In this study, we aimed to identify the most efficient sensory and motor spinal nerve roots involved in the micturition reflex. Unilateral L5-S2 dorsal and ventral roots were electrically stimulated, and bladder reflex contractions were recorded under isovolumetric conditions. Repeated stimulation of the L6 and S1 dorsal roots not only abolished bladder reflex contractions but also induced a poststimulation inhibitory effect, whereas repeated stimulation of the L5 and S2 dorsal roots had no effect. Only the L6 ventral root directly caused bladder contraction when ventral roots L5-S2 were stimulated in sequence. Upon retrograde tracing using pseudorabies virus (PRV), the sacral parasympathetic nucleus of the L6 segment had more PRV-positive cells than the other segments, though the S1 segment of the dorsal root ganglia had the highest density of PRV-positive neurons. These results suggest the L6 ventral root is most efficient in producing detrusor muscle contraction, and the S1 dorsal root best inhibits the micturition reflex. PMID- 29568365 TI - Amiodarone promotes cancer cell death through elevated truncated SRSF3 and downregulation of miR-224. AB - Amiodarone is a widely used class III antiarrhythmic agent which prolongs the action potential and refractory period by blockage of several types of myocardial potassium channels. Emerging evidence suggests that amiodarone sensitize tumor cells in response to chemotherapy. Nevertheless, little is known about the underlying molecular mechanism. To gain further insight, we demonstrated that amiodarone accumulated the population of a premature termination codon-containing isoform of serine and arginine rich splicing factor 3 (SRSF3-PTC) without increasing alternative spliced p53 beta isoform. Amiodarone enhanced reactive oxygen species production and increased cell apoptosis, whereas reduced DNA damage. Moreover, amiodarone suppressed miR-224 and increased its target COX-2 expression. Taken together, our results suggested amiodarone caused cancer cell death might be through increased SRSF3-PTC and miR-224 reduction in a p53 independent manner. PMID- 29568366 TI - Selenoprotein K deficiency inhibits melanoma by reducing calcium flux required for tumor growth and metastasis. AB - Interest has emerged in the therapeutic potential of inhibiting store operated calcium (Ca2+) entry (SOCE) for melanoma and other cancers because malignant cells exhibit a strong dependence on Ca2+ flux for disease progression. We investigated the effects of deleting Selenoprotein K (SELENOK) in melanoma since previous work in immune cells showed SELENOK was required for efficient Ca2+ flux through the endoplasmic reticulum Ca2+ channel protein, inositol 1,4,5 trisphosphate receptor (IP3R), which is due to the role SELENOK plays in palmitoylating and stabilizing the expression of IP3R. CRISPR/Cas9 was used to generate SELENOK-deficiency in human melanoma cells and this led to reduced Ca2+ flux and impaired IP3R function, which inhibited cell proliferation, invasion, and migration. Ca2+-dependent signaling through calcineurin was inhibited with SELENOK-deficiency, and gene array analyses together with evaluation of transcript and protein levels showed altered transcriptional programs that ultimately disrupted stemness and pro-growth properties. In vivo investigations were conducted using the Grm1-Tg transgenic mouse strain that develops spontaneous metastatic melanoma, which was crossed with SELENOK-/- mice to generate the following littermates: Grm1-Tg/SELENOK-/-, Grm1-Tg/SELENOK-/+, Grm1 Tg/SELENOK+/+. SELENOK-deficiency in Grm1-Tg/SELENOK-/- male and female mice inhibited primary tumor growth on tails and ears and reduced metastasis to draining lymph nodes down to levels equivalent to non-tumor control mice. Cancer stem cell pools were also decreased in Grm1-Tg/SELENOK-/- mice compared to littermates. These results suggest that melanoma requires SELENOK expression for IP3R dependent maintenance of stemness, tumor growth and metastasic potential, thus revealing a new potential therapeutic target for treating melanoma and possibly other cancers. PMID- 29568367 TI - The new allosteric inhibitor asciminib is susceptible to resistance mediated by ABCB1 and ABCG2 overexpression in vitro. AB - Asciminib (previously ABL001), which binds the myristate-binding pocket of the Bcr-Abl kinase domain, is in phase I clinical trials as monotherapy and in combination with imatinib, nilotinib and dasatinib for the treatment of patients with refractory CML or Ph+ ALL. Asciminib sensitivity was evaluated in asciminib naive BCR-ABL1+ cell lines K562 (negligible ABCB1/ABCG2 expression), K562-Dox (ABCB1-overexpressing through doxorubicin exposure) and K562-ABCG2 (ABCG2 overexpression via transduction) with results demonstrating asciminib efflux by both ABCB1 and ABCG2 transporters. K562-Dox and K562-ABCG2 cells demonstrated increased LD50asciminib vs K562 control cells: 256 and 299 nM respectively vs 24 nM, p < 0.001. Sensitivity was completely restored with specific inhibitors cyclosporine (ABCB1) and Ko143 (ABCG2): K562-Dox LD50asciminib+cyclosporine = 13 nM, K562-ABCG2 LD50asciminib+Ko143 = 15 nM (p < 0.001). When asciminib resistance was modelled in vitro, ABCB1 and ABCG2 overexpression was integral in the development of asciminib resistance. In K562 asciminib-resistant cells, ABCG2 expression increased prior to BCR-ABL1 overexpression and remained high (up to 7.6-fold greater levels in resistant vs control cells, p < 0.001). K562-Dox asciminib-resistant cells had increased ABCB1 expression (2.1-fold vs control cells p = 0.0033). KU812 asciminib-resistant cells overexpressed ABCB1 (5.4-fold increase, p < 0.001) and ABCG2 (6-fold increase, p < 0.001) before emergence of a novel myristate-binding pocket mutation (F497L). In all three cell lines, asciminib resistance was reversible upon chemical inhibition of ABCB1, ABCG2 or both (p < 0.001). When K562 asciminib-resistant cells were treated with asciminib in combination with clinically achievable doses of either imatinib or nilotinib, reversal of the resistance phenotype was also observed (p < 0.01). Overexpression of efflux transporters will likely be an important pathway for asciminib resistance in the clinical setting. Given the lack of evidence for ABCG2-mediated transport of nilotinib or imatinib at clinically relevant concentrations, our data provide an additional rationale for using asciminib in combination with either TKI. PMID- 29568368 TI - Trifluridine/tipiracil overcomes the resistance of human gastric 5-fluorouracil refractory cells with high thymidylate synthase expression. AB - Trifluridine/tipiracil (FTD/TPI or TFTD, also known as TAS-102) is a combination of the antineoplastic thymidine analog, FTD, and thymidine phosphorylase inhibitor, TPI (molar ratio 1:0.5). FTD/TPI was approved in Japan, the United States, and the European Union for the treatment of unresectable advanced or recurrent colorectal cancer. We evaluated the in vitro and in vivo efficacy and mechanisms of action of FTD and FTD/TPI against 5-fluorouracil (5-FU)-resistant MKN45/5FU, MKN74/5FU, and KATOIII/5FU human gastric cancer cells overexpressing thymidylate synthase (TS) and their respective parent cell lines. MKN45/5FU and KATOIII/5FU cells were not cross-resistant to FTD, whereas MKN45/5FU cells were 3.7-fold more resistant than the parental cells in vitro. FTD was also incorporated into genomic DNA in a concentration-dependent manner in 5-FU resistant and parental cells. Additionally, deoxyuridine monophosphate levels in MKN45/5FU cells after 24-h FTD treatment were 3.0-fold higher than those in parental cells, and FTD treatment for 72 h induced G2/M arrest in MKN45/5FU cells, unlike the S phase arrest in MKN45 cells. Thus, TS-overexpressing MKN45/5FU cells, but not MKN74/5FU and KATOIII/5FU cells, showed partial cross resistance to FTD. However, FTD/TPI (administered orally twice a day) exhibited antitumor activity to the same extent in MKN45 and MKN45/5FU xenograft mouse models, overcoming in vitro cross-resistance to FTD. DNA incorporation rather than TS inhibition seems to be the main action of FTD under these in vivo conditions. Thus, FTD/TPI is a promising chemotherapeutic agent against gastric cancers recurring following 5-FU therapy. PMID- 29568369 TI - Therapeutic significance of targeting survivin in cervical cancer and possibility of combination therapy with TRAIL. AB - Loss of p53 function due to human papillomavirus (HPV) infection induces resistance to apoptosis in cervical cancer cells. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), which induces apoptosis in a p53-independent manner, may provide an alternative strategy for treating cervical cancer. Survivin, an antiapoptotic protein that is highly expressed in cancer cells, regulates apoptosis and the cell cycle. Here, we investigated the therapeutic potential of targeting survivin, while focusing on the TRAIL-induced apoptosis pathway. The viability and cell cycle of HPV16-positive CaSki and SiHa cells were assessed after survivin knockdown by small interfering RNA (si-survivin). E cadherin expression was also assessed after si-survivin treatment, using western blotting. SiHa (a TRAIL-resistant cell line) was used for further studies. The small molecule YM155 and resveratrol (RVT; a polyphenol with the potential to suppress survivin expression) were used as survivin inhibitors. The effects of si survivin and survivin inhibitors on TRAIL- or cisplatin (CDDP)-induced apoptosis were analyzed by annexin-V staining. si-survivin treatment decreased cell viability and led to G2/M arrest, accompanied by morphological changes and E cadherin upregulation in both CaSki and SiHa cells. si-survivin and YM155 synergistically sensitized TRAIL-resistant SiHa cells to TRAIL-induced apoptosis (p < 0.05). However, si-survivin and YM155 only slightly increased CDDP-induced apoptosis. RVT markedly enhanced TRAIL-induced apoptosis by suppressing survivin expression. Targeting of survivin expression might be an ideal strategy for cervical cancer treatment as it would decrease viable cell number and enhance apoptosis sensitivity. Further, combination therapy with TRAIL, rather than CDDP, may be compatible with the proposed survivin-targeting strategy. PMID- 29568370 TI - Gram-negative bacteria facilitate tumor progression through TLR4/IL-33 pathway in patients with non-small-cell lung cancer. AB - Non-small-cell lung cancer (NSCLC) accounts for the most cases in clinical lung cancer patients. Patients with NSCLC are often diagnosed in advanced stage and frequently infected with gram-negative bacteria. Pulmonary infection with gram negative bacteria is the most frequent postoperative complication in NSCLC patients. While accumulating evidence indicate an involvement of gram-negative bacteria in NSCLC progression, the underlying mechanisms remain largely unknown. Herein, we explored the effect of gram-negative bacteria on tumor progression using tumor cells from NSCLC patients. We observed that infection with gram negative bacteria predicted advanced stages and decreased time interval to recurrence of NSCLC patients. Incubation of NSCLC cells with gram-negative bacteria promoted their growth and metastasis. Mechanistically, gram-negative bacteria activated Toll-like receptor 4 (TLR4) signaling in NSCLC cells, leading to increased mRNA and protein expression of interleukin 33 (IL-33) through MyD88 dependent pathway. Knockdown of IL-33 abrogated the contribution of gram-negative bacteria to NSCLC progression by regulating cancer metabolic activities and stem cell properties. In NSCLC patients, higher TLR4 expression was associated with increased IL-33 expression, Ki-67 proliferation index and CD133 expression in those with gram-negative bacterial infection. These findings shed new light on the molecular mechanisms underlie gram-negative bacteria mediated tumor progression and provide clues for innovative therapeutic explorations for NSCLC patients. PMID- 29568371 TI - CDK8/19 inhibition induces premature G1/S transition and ATR-dependent cell death in prostate cancer cells. AB - The CDK8/19 kinase module comprises a subcomplex that interacts with the Mediator complex and regulates gene expression through phosphorylation of transcription factors and Mediator subunits. Mediator complex subunits have been increasingly implicated in cancer and other diseases. Although high expression of CDK8/19 has been demonstrated in prostate cancer, its function has not been thoroughly examined. Here we report that CDK8/19 modulates the gene expression of cell cycle regulators and thereby maintains the proper G1/S transition in prostate cancer cells. We show that highly selective CDK8/19 inhibitors exerted anti proliferative activity in prostate cancer cells both in vitro and in vivo. In CDK8/19 inhibitor-sensitive prostate cancer cells, the compounds reduced the population of G1 phase cells and elevated that of S phase cells through the modulation of G1/S transition regulators at the level of mRNA expression. Furthermore, the premature G1/S transition induced a DNA damage response that was followed by ATR-dependent and caspase-independent cell death. These findings suggest a novel role of CDK8/19 in transcription-mediated cell cycle control, albeit with possible contribution of other proteins inhibited by the compounds. Our data provide a rationale for further investigation of CDK8/19 inhibitors as a new therapeutic approach to prostate cancer. PMID- 29568372 TI - Effects of Cetuximab and Erlotinib on the behaviour of cancer stem cells in head and neck squamous cell carcinoma. AB - The therapeutic responses of many solid tumours to chemo- and radio-therapies are far from fully effective but therapies targeting malignancy-related cellular changes show promise for further control. In head and neck squamous cell carcinoma, the epidermal growth factor receptor (EGFR) is commonly overexpressed and investigation of agents that block this receptor indicate a limited response when used alone but an ability to enhance the actions of other drugs. The hierarchical stem cell patterns present in tumours generate cellular heterogeneity and this is further complicated by cancer stem cells (CSC) shifting between epithelial (Epi-CSC) and mesenchymal (EMT-CSC) states. To clarify how such heterogeneity influences responses to EGFR blocking, we examined the effects of Cetuximab and Erlotinib on the cell sub-populations in HNSCC cell lines. These agents reduced cell proliferation for all subpopulations but induced little cell death. They did however induce large shifts of cells between the EMT-CSC, Epi-CSC and differentiating cell compartments. Loss of EMT-CSCs reduced cell motility and is expected to reduce invasion and metastasis. EGFR blocking also induced shifts of Epi-CSCs into the differentiating cell compartment which typically has greater sensitivity to chemo/radiation, an effect expected to enhance the overall response of tumour cell populations to adjunctive therapies. PMID- 29568373 TI - Increased expression of MNK1b, the spliced isoform of MNK1, predicts poor prognosis and is associated with triple-negative breast cancer. AB - MAP kinase interacting kinases (MNKs) modulate the function of oncogene eukaryotic initiation factor 4E (eIF4E) through phosphorylation, which is necessary for oncogenic transformation. MNK1 gives rise to two mRNAs and thus two MNK1 isoforms, named MNK1a and MNK1b. MNK1b, the splice variant of human MNK1a, is constitutively active and independent of upstream MAP kinases. In this study, we have analyzed the expression of both MNK1 isoforms in 69 breast tumor samples and its association with clinicopathologic/prognostic characteristics of breast cancer. MNK1a and MNK1b expression was significantly increased in tumors relative to the corresponding adjacent normal tissue (p < 0.001). In addition, MNK1b overexpression was found in most of the triple-negative tumors and was associated with a shorter overall and disease-free survival time. Overexpression of MNK1b in MDA-MB-231 cells induced an increase in the expression of the MCL1 antiapoptotic protein and promoted proliferation, invasion and colony formation. In conclusion, a high expression level of MNK1b protein could be used as a marker of poor prognosis in breast cancer patients and it could be a therapeutic target in triple-negative tumors. PMID- 29568374 TI - An open label trial of folate receptor-targeted intraoperative molecular imaging to localize pulmonary squamous cell carcinomas. AB - Background: Clinical applicability of folate receptor-targeted intraoperative molecular imaging (FR-IMI) has been established for surgically resectable pulmonary adenocarcinoma. A role for FR-IMI in other lung cancer histologies has not been studied. In this study, we evaluate feasibility of FR-IMI in patients undergoing pulmonary resection for squamous cell carcinomas (SCCs). Methods: In a human clinical trial (NCT02602119), twelve subjects with pulmonary SCCs underwent FR-IMI with a near-infrared contrast agent that targets the folate receptor-alpha (FRalpha), OTL38. Near-infrared signal from tumors and benign lung was quantified to calculate tumor-to-background ratios (TBR). Folate receptor-alpha expression was characterized, and histopathologic correlative analyses were performed to evaluate patterns of OTL38 accumulation. An exploratory analysis was performed to determine patient and histopathologic variables that predict tumor fluorescence. Results: 9 of 13 SCCs (in 9 of 12 of subjects) displayed intraoperative fluorescence upon NIR evaluation (median TBR, 3.9). OTL38 accumulated within SCCs in a FRalpha-dependent manner. FR-IMI was reliable in localizing nodules as small as 1.1 cm, and prevented conversion to thoracotomy for nodule localization in three subjects. Upon evaluation of patient and histopathologic variables, in situ fluorescence was associated with distance from the pleural surface, and was independent of alternative variables including tumor size and metabolic activity. Conclusions: This work demonstrates that FR-IMI is potentially feasible in 70% of SCC patients, and that molecular imaging can improve localization during minimally invasive pulmonary resection. These findings complement previous data demonstrating that ~98% of pulmonary adenocarcinomas are localized during FR-IMI and suggest broad applicability for NSCLC patients undergoing resection. PMID- 29568375 TI - Quantitative mass spectrometry analysis reveals a panel of nine proteins as diagnostic markers for colon adenocarcinomas. AB - Adenocarcinomas are cancers originating from the gland forming cells of the colon and rectal lining, and are known to be the most common type of colorectal cancers. The current diagnosis strategies for colorectal cancers include biopsy, laboratory tests, and colonoscopy which are time consuming. Identification of protein biomarkers could aid in the detection of colon adenocarcinomas (CACs). In this study, tissue proteome of colon adenocarcinomas (n = 11) was compared with the matched control specimens (n = 11) using isobaric tags for relative and absolute quantitation (iTRAQ) based liquid chromatography-mass spectrometry (LC MS/MS) approach. A list of 285 significantly altered proteins was identified in colon adenocarcinomas as compared to its matched controls, which are associated with growth and malignancy of the tumors. Protein interaction analysis revealed the association of altered proteins in colon adenocarcinomas with various transcription factors and their targets. A panel of nine proteins was validated using multiple reaction monitoring (MRM). Additionally, S100A9 was also validated using immunoblotting. The identified panel of proteins may serve as potential biomarkers and thereby aid in the detection of colon adenocarcinomas. PMID- 29568376 TI - CHL1 gene polymorphisms increase lung cancer susceptibility. AB - Lung cancer represents a complex and malignant cancer. Close Homologue of L1 (CHL1) gene plays a crucial role in the progress of cancer. The aim of this study is to explore the association between CHL1 rs425366 polymorphism and lung cancer susceptibility in northeast of China. A hospital-based case-control study was carried out to collect relative characteristics. Logistic regression analysis was conducted to analyze the relationship between single nucleotide polymorphisms and lung cancer susceptibility. The results suggested that there was statistically significant difference between GT genotype and TT genotype of rs425366 and lung cancer susceptibility. In stratified analysis, TT genotype of rs425366 may increase the risk of lung adenocarcinoma. We also found that non-smoking individuals carrying T allele were more likely to develop lung cancer. Overall, our study may indicate that CHL1 gene may increase lung cancer susceptibility in northeast of China. PMID- 29568377 TI - Molecular profiling of ALDH1+ colorectal cancer stem cells reveals preferential activation of MAPK, FAK, and oxidative stress pro-survival signalling pathways. AB - Tumour heterogeneity leads to variable clinical response and inaccurate diagnostic and prognostic assessment. Cancer stem cells (CSCs) represent a subpopulation responsible for invasion, metastasis, therapeutic resistance, and recurrence in many human cancer types. However, the true identity of colorectal cancer (CRC) SCs remains elusive. Here, we aimed to characterize and define the gene expression portrait of CSCs in CRC-model SW403 cells. We found that ALDH+ positive cells are clonogenic and highly proliferative; their global gene expression profiling-based molecular signature revealed gene enrichment related to DNA damage, MAPK, FAK, oxidative stress response, and Wnt signalling. ALDH+ cells showed enhanced ROS stress resistance, whereas MAPK/FAK pathway pharmacologic inhibition limited their survival. Conversely, 5-fluorouracil increased the ALDH+ cell fraction among the SW403, HCT116 and SW620 CRC models. Notably, analysis of ALDH1A1 and POU5F1 expression levels in cohorts of 462 or 420 patients for overall (OS) or disease-free (DFS) survival, respectively, obtained from the Cancer Genome Atlas CRC dataset, revealed strong association between elevated expression and poor OS (p = 0.006) and poor DFS (p = 0.05), thus implicating ALDH1A1 and POU5F1 in CRC prognosis. Our data reveal distinct molecular signature of ALDH+ CSCs in CRC and suggest pathways relevant for successful targeted therapies and management of CRC. PMID- 29568378 TI - Human tripartite motif protein 52 is required for cell context-dependent proliferation. AB - Tripartite motif (TRIM) proteins have been shown to play important roles in cancer development and progression by modulating cell proliferation or resistance from cell death during non-homeostatic stress conditions found in tumor micro environments. In this study, we set out to investigate the importance for cellular fitness of the virtually uncharacterized family member TRIM52. The human TRIM52 gene has arisen recently in evolution, making it unlikely that TRIM52 is required for basic cellular functions in normal cells. However, a recent genome wide ablation screening study has suggested that TRIM52 may be essential for optimal proliferation or survival in certain genetic cancer backgrounds. Identifying genes which fit this concept of genetic context-dependent fitness in cancer cells is of interest as they are promising targets for tumor-specific therapy. We report here that TRIM52 ablation significantly diminished the proliferation of specific glioblastoma cell lines in cell culture and mouse xenografts by compromising their cell cycle progression in a p53-dependent manner. Together, our findings point to a non-redundant TRIM52 function that is required for optimal proliferation. PMID- 29568379 TI - Leukocyte telomere length throughout the continuum of colorectal carcinogenesis. AB - Considering the high prevalence of colorectal cancer (CRC) and relatively high mortality there is strong interest in identification of clinically relevant biomarkers. Telomere shortening is supposed to contribute to genomic instability and crucially involved in process of carcinogenesis. Peripheral blood leukocyte (PBL) telomere length was previously investigated in several studies as potential biomarker for CRC but with controversial results. This prompted us to investigate relative PBL telomere length in association with different histological findings throughout the continuum of colorectal carcinogenesis in order to reflect the whole spectrum of putative CRC development in a large study involving 2011 individuals. The study based on the Colorectal Cancer Study of Austria (CORSA), including 384 CRC cases as well as age- and gender-matched 544 high-risk adenomas, 537 low-risk adenoma patients and 546 colonoscopy-negative controls. Relative expression of telomeric repeats and the single copy reference gene, albumin (T/S ratio) was determined using monochrome multiplex quantitative PCR (MMQPCR). Telomeres were found to be significantly longer in CRC patients compared to control subjects (P = 3.61x10-6). Yet, no significant differences in telomere length could be detected for high-risk (P = 0.05956) and low-risk colorectal adenoma patients (P = 0.05224). In addition, results presented in this manuscript highlight the impact of various epidemiological factors on PBL telomere length and its involvement in CRC. However, further large studies also including colorectal adenomas are necessary to confirm these results. PMID- 29568380 TI - Adenosine A2A receptor ligand recognition and signaling is blocked by A2B receptors. AB - The adenosine receptor (AR) subtypes A2A and A2B are rhodopsin-like Gs protein coupled receptors whose expression is highly regulated under pathological, e.g. hypoxic, ischemic and inflammatory conditions. Both receptors play important roles in inflammatory and neurodegenerative diseases, are blocked by caffeine, and have now become major drug targets in immuno-oncology. By Forster resonance energy transfer (FRET), bioluminescence resonance energy transfer (BRET), bimolecular fluorescence complementation (BiFC) and proximity ligation assays (PLA) we demonstrated A2A-A2BAR heteromeric complex formation. Moreover we observed a dramatically altered pharmacology of the A2AAR when co-expressed with the A2BAR (A2B >= A2A) in recombinant as well as in native cells. In the presence of A2BARs, A2A-selective ligands lost high affinity binding to A2AARs and displayed strongly reduced potency in cAMP accumulation and dynamic mass redistribution (DMR) assays. These results have major implications for the use of A2AAR ligands as drugs as they will fail to modulate the receptor in an A2A-A2B heteromer context. Accordingly, A2A-A2BAR heteromers represent novel pharmacological targets. PMID- 29568381 TI - Nuclear myosin/actin-motored contact between homologous chromosomes is initiated by ATM kinase and homology-directed repair proteins at double-strand DNA breaks to suppress chromosome rearrangements. AB - We provide evidence for a mechanism of DNA repair that requires nuclear myosin/actin-dependent contact between homologous chromosomes to prevent formation of chromosomal rearrangement in human cells. We recently showed that DNA double strand breaks (DSBs) induced by gamma-rays or endonucleases cause ATM dependent contact formation between homologous chromosomes at damaged sites of transcriptionally active chromatin in G0/G1-phase cells. Here, we report that the mechanism of contact generation between homologous chromosomes also requires homology-directed repair proteins, including BRCA1, RAD51 and RAD52, and nuclear myosin/actin-motors. Moreover, inhibition of ATM kinase or deficiency in nuclear actin polymerization causes carcinogenic RET/PTC chromosome rearrangements after DSBs induction in human cells. These data suggest that DSBs in transcriptionally active euchromatin in G0/G1-phase cells are repaired through a mechanism that requires contact formation between homologous chromosomes and that this mechanism is mediated by HDR proteins and nuclear myosin/actin motors. PMID- 29568382 TI - Prolonged in vivo expression and anti-tumor response of DNA-based anti-HER2 antibodies. AB - Antibody gene transfer presents an appealing alternative to conventional antibody protein therapy. This pre-clinical study evaluates the impact of various parameters on the pharmacokinetics and efficacy of in vivo expressed DNA-based anti-HER2 monoclonal antibodies (mAbs), newly engineered and delivered via intramuscular electrotransfer in mice. Plasma concentrations of trastuzumab and 4D5, its murine IgG1 equivalent, peaked on average between 1-15 ug/ml, depending on the administration and configuration of the encoding plasmid DNA (pDNA). A dual expression cassette system outperformed a single 2A-based cassette, and the CAG promoter was superior to a muscle-specific DeltaUSE-based promoter. A 'gene therapy-compatible' Gene Transport Unit (gtGTU, FIT Biotech), a plasmid backbone that co-encodes viral elements, failed to improve in vivo reporter and mAb expression compared to a conventional plasmid. In BALB/c mice, trastuzumab detection was lost within two weeks after pDNA administration due to anti-drug antibodies. This host immune response was addressed by expressing trastuzumab in immune-compromised mice, or by gene transfer of murine 4D5 in BALB/c mice. Both approaches maintained single-digit ug/ml mAb concentrations for at least six to nine months, and allowed to boost mAb expression over time by pDNA re-dosing. In a breast cancer mouse model, prophylactic and therapeutic DNA-based trastuzumab or 4D5 led to complete tumor regressions, thereby rivalling with the administration of milligrams of mAb protein. In conclusion, our study demonstrates proof of concept for antibody gene transfer in cancer, provides critical insights in the engineering and application of DNA-based antibodies, and serves to advance this modality in oncology and beyond. PMID- 29568383 TI - Protective role of integrin-linked kinase against oxidative stress and in maintenance of genomic integrity. AB - The balance between the production of reactive oxygen species and activation of antioxidant pathways is essential to maintain a normal redox state in all tissues. Oxidative stress caused by excessive oxidant species generation can cause damage to DNA and other macromolecules, affecting cell function and viability. Here we show that integrin-linked kinase (ILK) plays a key role in eliciting a protective response to oxidative damage in epidermal cells. Inactivation of the Ilk gene causes elevated levels of intracellular oxidant species (IOS) and DNA damage in the absence of exogenous oxidative insults. In ILK-deficient cells, excessive IOS production can be prevented through inhibition of NADPH oxidase activity, with a concomitant reduction in DNA damage. Additionally, ILK is necessary for DNA repair processes following UVB-induced damage, as ILK-deficient cells show a significantly impaired ability to remove cyclobutane pyrimidine dimers following irradiation. Thus, ILK is essential to maintain cellular redox balance and, in its absence, epidermal cells become more susceptible to oxidative damage through mechanisms that involve IOS production by NADPH oxidase activity. PMID- 29568384 TI - Structural insights into drug development strategy targeting EGFR T790M/C797S. AB - Treatment of non-small-cell lung cancers (NSCLCs) harboring primary EGFR oncogenic mutations such as L858R and exon 19 deletion delE746_A750 (Del-19) using gefitinib/erlotinib ultimately fails due to the emergence of T790M mutation. Though WZ4002/CO-1686/AZD9291 are effective in overcoming EGFR T790M by targeting Cys797 via covalent bonding, their efficacy is again limited due to the emergence of C797S mutation. New agents effectively inhibiting EGFR T790M without covalent linkage through Cys 797 may solve this problem. We presented here crystal structures of EGFR activating/drug-resistant mutants in complex with a panel of reversible inhibitors along with mutagenesis and enzyme kinetic data. These data revealed a previously un-described hydrophobic clamp structure in the EGFR kinase which may be exploited to facilitate development of next generation drugs targeting EGFR T790M with or without concomitant C797S. Interestingly, mutations in the hydrophobic clamp that hinder drug binding often also weaken ATP binding and/or abolish kinase activity, thus do not readily result in resistance to the drugs. PMID- 29568385 TI - Persistent DNA strand breaks induce a CAF-like phenotype in normal fibroblasts. AB - Cancer-associated fibroblasts (CAFs) are an emerging target for cancer therapy as they promote tumour growth and metastatic potential. However, CAF targeting is complicated by the lack of knowledge-based strategies aiming to selectively eliminate these cells. There is a growing body of evidence suggesting that a pro inflammatory microenvironment (e.g. ROS and cytokines) promotes CAF formation during tumorigenesis, although the exact mechanisms involved remain unclear. In this study, we reveal that a prolonged pro-inflammatory stimulation causes a de facto deficiency in base excision repair, generating unrepaired DNA strand breaks and thereby triggering an ATF4-dependent reprogramming of normal fibroblasts into CAF-like cells. Based on the phenotype of in vitro-generated CAFs, we demonstrate that midostaurin, a clinically relevant compound, selectively eliminates CAF-like cells deficient in base excision repair and prevents their stimulatory role in cancer cell growth and migration. PMID- 29568386 TI - Correlation of MET gene amplification and TP53 mutation with PD-L1 expression in non-small cell lung cancer. AB - Background: The role of MET amplification in lung cancer, particularly in relation to checkpoint inhibition and EGFR WT, has not been fully explored. In this study, we correlated PD-L1 expression with MET amplification and EGFR, KRAS, or TP53 mutation in primary lung cancer. Methods: In this retrospective study, tissue collected from 471 various tumors, including 397 lung cancers, was tested for MET amplification by FISH with a MET/centromere probe. PD-L1 expression was evaluated using clone SP142 and standard immunohistochemistry, and TP53, KRAS, and EGFR mutations were tested using next generation sequencing. Results: Our results revealed that PD-L1 expression in non-small cell lung cancer is inversely correlated with EGFR mutation (P=0.0003), and positively correlated with TP53 mutation (P=0.0001) and MET amplification (P=0.004). Patients with TP53 mutations had significantly higher MET amplification (P=0.007), and were more likely (P=0.0002) to be EGFR wild type. There was no correlation between KRAS mutation and overall PD-L1 expression, but significant positive correlation between PD-L1 expression and KRAS with TP53 co-mutation (P=0.0002). A cut-off for the ratio of MET: centromere signal was determined as 1.5%, and 4% of lung cancer patients were identified as MET amplified. Conclusions: This data suggests that in lung cancer both MET and TP53 play direct roles in regulating PD-L1 opposing EGFR. Moreover, KRAS and TP53 co-mutation may cooperate to drive PD-L1 expression in lung cancer. Adding MET or TP53 inhibitors to checkpoint inhibitors may be an attractive combination therapy in patients with lung cancer and MET amplification. PMID- 29568387 TI - Engineered T lymphocytes eliminate lung metastases in models of pancreatic cancer. AB - Pancreatic cancer is known as one of the most lethal cancers in the world. A majority of advanced stage pancreatic cancer patients are diagnosed with distant metastasis and given poor prognoses, calling for a better therapeutic option. Mesothelin, which is overexpressed in pancreatic cancer and other solid tumors, is a potential target for pancreatic cancer immunotherapy. Adoptive transfer of T cells engineered with chimeric antigen receptors (CART cells) was effective for treating CD19-positive leukemia, but it is more difficult for CART cells to eliminate solid tumors. Because distal metastasis is an important malignant behavior of solid tumors, we investigated whether meso-CART cells exert anti tumor effects against distant metastases. After expressing meso-CAR in human primary T lymphocytes, the resultant meso-CART cells released cytokines in response to and exhibited cytolytic effects on mesothelin-positive tumor cells in vitro. Injection of meso-CART cells into tumor-bearing mice moderately delayed subcutaneous tumor growth and eliminated lung metastases. This is the first study to show that meso-CART cells are effective against lung metastases induced by intravenous injection of pancreatic tumor cells. Our results suggest that meso CART cells may be an effective clinical treatment for mesothelin-positive primary and metastatic tumors in pancreatic cancer patients. PMID- 29568388 TI - Inter-assay precision of clonogenic assays for radiosensitivity in cancer cell line A549. AB - Clonogenic assays are the gold standard for determining radiosensitivity, which governs tumor response to radiation therapy. Although multiple studies of clonogenic assays on cancer cell lines have been published, the robustness of this technique has not been examined by comparative analysis of data from different studies. To address this issue, we investigated the inter-assay precision of clonogenic assays by analyzing in-house and published data on A549, a cell line frequently studied in this context. The coefficients of variation for SF2, the surviving fraction after 2 Gy irradiation, and D10, the radiation dose that reduces survival to 10%, were below 30% for both in-house data obtained from 20 independent experiments performed under consistent experimental settings (i.e., radiation type, dose rate, and timing of cell seeding) and data collected from 192 publications using diverse experimental settings. Multivariate analyses of the published data revealed that timing of cell seeding significantly affected SF2. These data indicate that SF2 and D10 of clonogenic assay have acceptable inter-assay precision, and that timing of cell seeding influences the inter-assay precision of SF2. These results provide a rationale for combined analysis of published clonogenic assay data, which may help to discover robust biological properties associated with tumor radiosensitivity. PMID- 29568389 TI - Computational modeling suggests impaired interactions between NKX2.5 and GATA4 in individuals carrying a novel pathogenic D16N NKX2.5 mutation. AB - NKX2.5, a homeobox containing gene, plays an important role in embryonic heart development and associated mutations are linked with various cardiac abnormalities. We sequenced the NKX2.5 gene in 100 congenital heart disease (CHD) patients and 200 controls. Our analysis revealed a total of 7 mutations, 3 in intronic region, 3 in coding region and 1 in 3' UTR. Of the above mutations, one mutation was found to be associated with tetralogy of fallot (TOF) and two (rs2277923 and a novel mutation, D16N) were strongly associated with VSD. A novel missense mutation, D16N (p-value =0.009744), located in the tinman (TN) region and associated with ventricular septal defect (VSD), is the most significant findings of this study. Computational analysis revealed that D16N mutation is pathogenic in nature. Through the molecular modeling, docking and molecular dynamics simulation studies, we have identified the location of mutant D16N in NKX2.5 and its interaction map with other partners at the atomic level. We found NKX2.5-GATA4 complex is stable, however, in case of mutant we observed significant conformational changes and loss of key polar interactions, which might be a cause of the pathogenic behavior. This study underscores the structural basis of D16N pathogenic mutation in the regulation of NKX2.5 and how this mutation renders the structural-functional divergence that possibly leading towards the diseased state. PMID- 29568390 TI - Characterization of brain tumor initiating cells isolated from an animal model of CNS primitive neuroectodermal tumors. AB - CNS Primitive Neuroectodermal tumors (CNS-PNETs) are members of the embryonal family of malignant childhood brain tumors, which remain refractory to current therapeutic treatments. Current paradigm of brain tumorigenesis implicates brain tumor-initiating cells (BTIC) in the onset of tumorigenesis and tumor maintenance. However, despite their significance, there is currently no comprehensive characterization of CNS-PNETs BTICs. Recently, we described an animal model of CNS-PNET generated by orthotopic transplantation of human Radial Glial (RG) cells - the progenitor cells for adult neural stem cells (NSC) - into NOD-SCID mice brain and proposed that BTICs may play a role in the maintenance of these tumors. Here we report the characterization of BTIC lines derived from this CNS-PNET animal model. BTIC's orthotopic transplantation generated highly aggressive tumors also characterized as CNS-PNETs. The BTICs have the hallmarks of NSCs as they demonstrate self-renewing capacity and have the ability to differentiate into astrocytes and early migrating neurons. Moreover, the cells demonstrate aberrant accumulation of wild type tumor-suppressor protein p53, indicating its functional inactivation, highly up-regulated levels of onco protein cMYC and the BTIC marker OCT3/4, along with metabolic switch to glycolysis - suggesting that these changes occurred in the early stages of tumorigenesis. Furthermore, based on RNA- and DNA-seq data, the BTICs did not acquire any transcriptome-changing genomic alterations indicating that the onset of tumorigenesis may be epigenetically driven. The study of these BTIC self renewing cells in our model may enable uncovering the molecular alterations that are responsible for the onset and maintenance of the malignant PNET phenotype. PMID- 29568391 TI - Proline oxidase silencing induces proline-dependent pro-survival pathways in MCF 7 cells. AB - Proline degradation by proline dehydrogenase/proline oxidase (PRODH/POX) contributes to apoptosis or autophagy. The identification of specific pathway of apoptosis/survival regulation is the aim of this study. We generated knocked-down PRODH/POX MCF-7 breast cancer cells (MCF-7shPRODH/POX). PRODH/POX silencing did not affect cell viability. However, it contributed to decrease in DNA and collagen biosynthesis, increase in prolidase activity and intracellular proline concentration as well as increase in the expression of iNOS, NF-kappaB, mTOR, HIF 1alpha, COX-2, AMPK, Atg7 and Beclin-1 in MCF-7shPRODH/POX cells. In these cells, glycyl-proline (GlyPro, substrate for prolidase) further inhibited DNA and collagen biosynthesis, maintained high prolidase activity, intracellular concentration of proline and up-regulated HIF-1alpha, AMPK, Atg7 and Beclin-1, compared to GlyPro-treated MCF-7 cells. In MCF-7 cells, GlyPro increased collagen biosynthesis, concentration of proline and expression of caspase-3, cleaved caspases -3 and -9, iNOS, NF-kappaB, COX-2 and AMPKbeta. PRODH/POX knock-down contributed to pro-survival autophagy pathways in MCF-7 cells and GlyPro-derived proline augmented this process. However, GlyPro induced apoptosis in PRODH/POX expressing MCF-7 cells as detected by up-regulation of active caspases -3 and -9. The data suggest that PRODH/POX silencing induces autophagy in MCF-7 cells and GlyPro-derived proline supports this process. PMID- 29568392 TI - MicroRNA-630 may confer favorable cisplatin-based chemotherapy and clinical outcomes in non-small cell lung cancer by targeting Bcl-2. AB - MicroRNA-630 (miR-630) plays dual roles in tumor progression in various human cancers. However, the role of miR-630 in chemoresistance and prognosis in non small cell lung cancer (NSCLC) remains to be elucidated. This retrospective study enrolled 114 surgically resected patients with NSCLC who experienced tumor relapse and underwent cisplatin-based chemotherapy. The aim was to examine the possible association between miR-630 (and its targeting of Bcl-2 expression) and the response to cisplatin-based chemotherapy. Patients with tumors expressing low miR-630, high Bcl-2, and a combination of both were more likely than their counterparts to show unfavorable responses to cisplatin-based chemotherapy. Kaplan-Meier and Cox regression analysis indicated that low miR-630, high Bcl-2, and a combination of both may independently predict poor overall survival and short relapse-free survival in patients with NSCLC. Six types of NSCLC cells were collected to determine the inhibitory concentration of cisplatin yielding 50% viability (IC50) by the MTT assay. The IC50 value for cisplatin was negatively correlated with miR-630 expression levels among these cell types, except for A549 cells. Mechanistically, low miR-630 expression conferred cisplatin resistance and colony formation by de-targeting Bcl-2 in NSCLC cells. We therefore suggest that low miR-630, high Bcl-2, and a combination of both may potentially predict an unfavorable chemotherapeutic response and poor outcome in patients with NSCLC. PMID- 29568393 TI - Artificial neural network approach to predict surgical site infection after free flap reconstruction in patients receiving surgery for head and neck cancer. AB - Background: The aim of this study was to develop an effective surgical site infection (SSI) prediction model in patients receiving free-flap reconstruction after surgery for head and neck cancer using artificial neural network (ANN), and to compare its predictive power with that of conventional logistic regression (LR). Materials and methods: There were 1,836 patients with 1,854 free-flap reconstructions and 438 postoperative SSIs in the dataset for analysis. They were randomly assigned tin ratio of 7:3 into a training set and a test set. Based on comprehensive characteristics of patients and diseases in the absence or presence of operative data, prediction of SSI was performed at two time points (pre operatively and post-operatively) with a feed-forward ANN and the LR models. In addition to the calculated accuracy, sensitivity, and specificity, the predictive performance of ANN and LR were assessed based on area under the curve (AUC) measures of receiver operator characteristic curves and Brier score. Results: ANN had a significantly higher AUC (0.892) of post-operative prediction and AUC (0.808) of pre-operative prediction than LR (both P<0.0001). In addition, there was significant higher AUC of post-operative prediction than pre-operative prediction by ANN (p<0.0001). With the highest AUC and the lowest Brier score (0.090), the post-operative prediction by ANN had the highest overall predictive performance. Conclusion: The post-operative prediction by ANN had the highest overall performance in predicting SSI after free-flap reconstruction in patients receiving surgery for head and neck cancer. PMID- 29568394 TI - Cardiac glycoside bufalin blocks cancer cell growth by inhibition of Aurora A and Aurora B activation via PI3K-Akt pathway. AB - In our previous study, cardiac glycosides including bufalin, a group of sodium pump (Na+/K+-ATPase) inhibitors widely used to treat heart failure for many years, have been demonstrated to induce a delay of mitotic entry and mitotic arrest in many cancer cells. However, the underlying mechanism remains poorly understood. Here, we reported for the first time that cardiac glycoside bufalin induced mitotic entry delay and prometaphase arrest by inhibition of activation of Aurora A/B. Furthermore, cardiac glycoside bufalin prevented Aurora A recruitment to mitotic centrosomes and Aurora B recruitment to unattached kinetochores. Mechanistically, bufalin and knockdown of sodium pump inhibited PI3K-Akt pathway, which in turn inhibit the activation of Aurora A/B, followed by a delay in mitotic entry and mitotic arrest. These actions were reversed by overexpression of Akt. In addition, ERK, mTOR, and ROS are not involved in bufalin-mediated downregulation of active form of Aurora A/B. Taken together, cardiac glycoside bufalin induces mitotic entry delay and mitotic arrest in cancer cells through inhibition of Aurora A/B activation via PI3K-Akt pathway. Based on this novel finding we could suggest that targeting PI3K-Akt pathway may have therapeutic value for the treatment of cancers associated with sodium pump overexpression. PMID- 29568395 TI - Merestinib (LY2801653) inhibits neurotrophic receptor kinase (NTRK) and suppresses growth of NTRK fusion bearing tumors. AB - Merestinib is an oral multi-kinase inhibitor targeting a limited number of oncokinases including MET, AXL, RON and MKNK1/2. Here, we report that merestinib inhibits neurotrophic receptor tyrosine kinases NTRK1/2/3 which are oncogenic drivers in tumors bearing NTRK fusion resulting from chromosomal rearrangements. Merestinib is shown to be a type II NTRK1 kinase inhibitor as determined by x-ray crystallography. In KM-12 cells harboring TPM3-NTRK1 fusion, merestinib exhibits potent p-NTRK1 inhibition in vitro by western blot and elicits an anti proliferative response in two- and three-dimensional growth. Merestinib treatment demonstrated profound tumor growth inhibition in in vivo cancer models harboring either a TPM3-NTRK1 or an ETV6-NTRK3 gene fusion. To recapitulate resistance observed from type I NTRK kinase inhibitors entrectinib and larotrectinib, we generated NIH-3T3 cells exogenously expressing TPM3-NTRK1 wild-type, or acquired mutations G595R and G667C in vitro and in vivo. Merestinib blocks tumor growth of both wild-type and mutant G667C TPM3-NTRK1 expressing NIH-3T3 cell-derived tumors. These preclinical data support the clinical evaluation of merestinib, a type II NTRK kinase inhibitor (NCT02920996), both in treatment naive patients and in patients progressed on type I NTRK kinase inhibitors with acquired secondary G667C mutation in NTRK fusion bearing tumors. PMID- 29568396 TI - Integrated DNA methylation analysis identifies topographical and tumoral biomarkers in pilocytic astrocytomas. AB - Pilocytic astrocytoma (PA) is the most common glioma in pediatric patients and occurs in different locations. Chromosomal alterations are mostly located at chromosome 7q34 comprising the BRAF oncogene with consequent activation of the mitogen-activated protein kinase pathway. Although genetic and epigenetic alterations characterizing PA from different localizations have been reported, the role of epigenetic alterations in PA development is still not clear. The aim of this study was to investigate whether distinctive methylation patterns may define biologically relevant groups of PAs. Integrated DNA methylation analysis was performed on 20 PAs and 4 normal brain samples by Illumina Infinium HumanMethylation27 BeadChips. We identified distinct methylation profiles characterizing PAs from different locations (infratentorial vs supratentorial) and tumors with onset before and after 3 years of age. These results suggest that PA may be related to the specific brain site where the tumor arises from region specific cells of origin. We identified and validated in silico the methylation alterations of some CpG islands. Furthermore, we evaluated the expression levels of selected differentially methylated genes and identified two biomarkers, one, IRX2, related to the tumor localization and the other, TOX2, as tumoral biomarker. PMID- 29568397 TI - Nucleolar stress enhances lytic reactivation of the Kaposi's sarcoma-associated herpesvirus. AB - Kaposi's sarcoma-associated herpesvirus (KSHV) is a human tumorigenic virus exhibiting two forms of infection, latent and lytic. Latent infection is abortive and allows the virus to establish lifelong infection, while lytic infection is productive, and is needed for virus dissemination within the host and between hosts. Latent infection may reactivate and switch towards the lytic cycle. This switch is a critical step in the maintenance of long-term infection and for the development of KSHV-related neoplasms. In this study, we examined the effect of nucleolar stress, manifested by failure in ribosome biogenesis or function and often coupled with p53 activation, on lytic reactivation of KSHV. To this end, we induced nucleolar stress by treatment with Actinomycin D, CX-5461 or BMH-21. Treatment with these compounds alone did not induce the lytic cycle. However, enhancement of the lytic cycle by these compounds was evident when combined with expression of the viral protein K-Rta. Further experiments employing combined treatments with Nutlin-3, knock-down of p53 and isogenic p53+/+ and p53-/- cells indicated that the enhancement of lytic reactivation by nucleolar stress does not depend on p53. Thus, our study identifies nucleolar stress as a novel regulator of KSHV infection, which synergizes with K-Rta expression to increase lytic reactivation. This suggests that certain therapeutic interventions, which induce nucleolar stress, may affect the outcome of KSHV infection. PMID- 29568398 TI - Bcl-xL as a poor prognostic biomarker and predictor of response to adjuvant chemotherapy specifically in BRAF-mutant stage II and III colon cancer. AB - Purpose: BRAF mutation occurs in 8-15% of colon cancers (CC), and is associated with poor prognosis in metastatic disease. Compared to wild-type BRAF (BRAFWT) disease, stage II/III CC patients with BRAF mutant (BRAFMT) tumors have shorter overall survival after relapse; however, time-to-relapse is not significantly different. The aim of this investigation was to identify, and validate, novel predictors of relapse of stage II/III BRAFMT CC. Experimental design: We used gene expression data from a cohort of 460 patients (GSE39582) to perform a supervised classification analysis based on risk-of-relapse within BRAFMT stage II/III CC, to identify transcriptomic biomarkers associated with prognosis within this genotype. These findings were validated using immunohistochemistry in an independent population-based cohort of Stage II/III CC (n = 691), applying Cox proportional hazards analysis to determine associations with survival. Results: High gene expression levels of Bcl-xL, a key regulator of apoptosis, were associated with increased risk of relapse, specifically in BRAFMT tumors (HR = 8.3, 95% CI 1.7-41.7), but not KRASMT/BRAFWT or KRASWT/BRAFWT tumors. High Bcl-xL protein expression in BRAFMT, untreated, stage II/III CC was confirmed to be associated with an increased risk of death in an independent cohort (HR = 12.13, 95% CI 2.49-59.13). Additionally, BRAFMT tumors with high levels of Bcl-xL protein expression appeared to benefit from adjuvant chemotherapy (P for interaction = 0.006), indicating the potential predictive value of Bcl-xL expression in this setting. Conclusions: These findings provide evidence that Bcl xL gene and/or protein expression identifies a poor prognostic subgroup of BRAFMT stage II/III CC patients, who may benefit from adjuvant chemotherapy. PMID- 29568399 TI - CTBP1 and metabolic syndrome induce an mRNA and miRNA expression profile critical for breast cancer progression and metastasis. AB - Metastatic breast cancer (BrCa) is still one of the main causes of cancer death in women. Metabolic syndrome (MeS), a risk factor for BrCa, is associated to high grade tumors, increased metastasis and recurrence of this disease. C-terminal binding protein 1 (CTBP1) is a co-repressor of tumor suppressor genes that is activated by low NAD+/NADH ratio. Previously, we demonstrated that CTBP1 hyperactivation by MeS increased tumor growth in MDA-MB-231-derived xenografts regulating several genes and miRNAs. In this work, our aim was to elucidate the role of CTBP1 and MeS in BrCa metastasis. We found that CTBP1 protein diminished adhesion while increased migration of triple negative BrCa cells. CTBP1 and MeS modulated the expression of multiple genes (ITGB4, ITGB6, PRSS2, COL17A1 and FABP4) and miRNAs (miR-378a-3p, miR-146a-5p, let-7e-3p, miR-381-5p, miR-194-5p, miR-494-3p) involved in BrCa progression of MDA-MB-231-derived xenografts. Furthermore, we demonstrated that MeS increased lung micrometastasis and liver neoplastic disease in mice. CTBP1 hyperactivation seems to be critical for MeS effect on BrCa metastasis since CTBP1 depletion completely impaired the detection of circulating tumor cells. Our results highlight CTBP1 and MeS impact on BrCa progression positioning them as key properties to be considered for BrCa patient prognosis and management. PMID- 29568400 TI - Chemopreventive effects of angiotensin II receptor type 2 agonist on prostate carcinogenesis by the down-regulation of the androgen receptor. AB - We recently reported that angiotensin II receptor blockers (ARBs) have chemopreventive and chemotherapeutic potential against prostate cancer via the reduction of androgen receptor (AR) expression. In this study, we investigated the effects of the angiotensin II receptor type 2 (AT2R) agonist Compound 21 (C21), which is expected to play similar roles to an ARB, on prostate carcinogenesis using the transgenic rat for adenocarcinoma of prostate (TRAP) model previously established in our laboratory. In vitro analyses of the cell growth, Western blotting and reporter gene assays were performed using LNCaP cells. TRAP rats at 6 weeks of age were randomly divided into 3 groups of 12 animals each and treated with C21 at 1 or 2 mg/kg/day in drinking water for 12 weeks. C21 reduced the proliferation activity of prostate cancer cells and down regulated the PSA promoter activity and the AR protein expression. We discovered that C21 inhibited the progression of prostate carcinogenesis in TRAP rats and decreased the incidence of adenocarcinoma in the lateral prostate. A significant increase in the apoptotic index with activation of caspase 3 and 7 were observed by immunohistochemistry and Western blotting analyses. C21 also down-regulated the expression of AR significantly in TRAP rat prostate. C21 decreased the expression of AR and reduced the proliferation activity effectively in prostate cancer cells and TRAP rat prostate. These findings suggest that AT2R agonist may be a candidate novel chemopreventive agent against human prostate cancer. PMID- 29568401 TI - A single digital droplet PCR assay to detect multiple KIT exon 11 mutations in tumor and plasma from patients with gastrointestinal stromal tumors. AB - Background: Gastrointestinal stromal tumors (GISTs) are characterized by oncogenic KIT mutations that cluster in two exon 11 hotspots. The aim of this study was to develop a single, sensitive, quantitative digital droplet PCR (ddPCR) assay for the detection of common exon 11 mutations in both GIST tumor tissue and in circulating tumor DNA (ctDNA) isolated from GIST patients' plasma. Methods: A ddPCR assay was designed using two probes that cover both hotspots. Available archival FFPE tumor tissue from 27 consecutive patients with known KIT exon 11 mutations and 9 randomly selected patients without exon 11 mutations were tested. Plasma samples were prospectively collected in a multicenter bio-databank from December 2014. ctDNA was analyzed of 22 patients with an exon 11 mutation and a baseline plasma sample. Results: The ddPCR assay detected the exon 11 mutation in 21 of 22 tumors with exon 11 mutations covered by the assay. Mutations in ctDNA were detected at baseline in 13 of 14 metastasized patients, but in only 1 of 8 patients with localized disease. In serial plasma samples from 11 patients with metastasized GIST, a decrease in mutant droplets was detected during treatment. According to RECIST 1.1, 10 patients had radiological treatment response and one patient stable disease. Conclusion: A single ddPCR assay for the detection of multiple exon 11 mutations in ctDNA is a feasible, promising tool for monitoring treatment response in patients with metastasized GIST and should be further evaluated in a larger cohort. PMID- 29568402 TI - Structural considerations for functional anti-EGFR * anti-CD3 bispecific diabodies in light of domain order and binding affinity. AB - We previously reported a functional humanized bispecific diabody (bsDb) that targeted EGFR and CD3 (hEx3-Db) and enhancement of its cytotoxicity by rearranging the domain order in the V domain. Here, we further dissected the effect of domain order in bsDbs on their cross-linking ability and binding kinetics to elucidate general rules regarding the design of functional bsDbs. Using Ex3-Db as a model system, we first classified the four possible domain orders as anti-parallel (where both chimeric single-chain components are variable heavy domain (VH)-variable light domain (VL) or VL-VH order) and parallel types (both chimeric single-chain components are mixed with VH-VL and VL-VH order). Although anti-parallel Ex3-Dbs could cross-link the soluble target antigens, their cross-linking ability between soluble targets had no correlation with their growth inhibitory effects. In contrast, the binding affinity of one of the two constructs with a parallel-arrangement V domain was particularly low, and structural modeling supported this phenomenon. Similar results were observed with E2x3-Dbs, in which the V region of the anti-EGFR antibody clone in hEx3 was replaced with that of another anti-EGFR clone. Only anti-parallel types showed affinity-dependent cancer inhibitory effects in each molecule, and E2x3-LH (both components in VL-VH order) showed the most intense anti-tumor activity in vitro and in vivo. Our results showed that, in addition to rearranging the domain order of bsDbs, increasing their binding affinity may be an ideal strategy for enhancing the cytotoxicity of anti-parallel constructs and that E2x3-LH is particularly attractive as a candidate next-generation anti-cancer drug. PMID- 29568403 TI - Exosomal microRNA profiling to identify hypoxia-related biomarkers in prostate cancer. AB - Hypoxia and expression of hypoxia-related biomarkers are associated with disease progression and treatment failure in prostate cancer (PCa). We have reported that exosomes (nanovesicles of 30-150 nm in diameter) secreted by human PCa cells under hypoxia promote invasiveness and stemness in naive PCa cells. Here, we identified the unique microRNAs (miRNAs) loaded in exosomes secreted by PCa cells under hypoxia. Using TaqMan(r) array microRNA cards, we analyzed the miRNA profile in exosomes secreted by human PCa LNCaP cells under hypoxic (ExoHypoxic) and normoxic (ExoNormoxic) conditions. We identified 292 miRNAs loaded in both ExoHypoxic and ExoNormoxic. The top 11 miRNAs with significantly higher level in ExoHypoxic compared to ExoNormoxic were miR-517a, miR-204, miR-885, miR-143, miR 335, miR-127, miR-542, miR-433, miR-451, miR-92a and miR-181a; and top nine miRNA with significantly lower expression level in ExoHypoxic compared to ExoNormoxic were miR-521, miR-27a, miR-324, miR-579, miR-502, miR-222, miR-135b, miR-146a and miR-491. Importantly, the two differentially expressed miRNAs miR-885 (increased expression) and miR-521 (decreased expression) showed similar expression pattern in exosomes isolated from the serum of PCa patients compared to healthy individuals. Additionally, miR-204 and miR-222 displayed correlated expression patterns in prostate tumors (Pearson R = 0.66, p < 0.0001) by The Cancer Genome Atlas (TCGA) prostate adenocarcinoma (PRAD) genomic dataset analysis. Overall, the present study identified unique miRNAs with differential expression in exosomes secreted from hypoxic PCa cells and suggests their potential usefulness as a biomarker of hypoxia in PCa patients. PMID- 29568404 TI - Long non-coding RNA XIST as a potential prognostic biomarker in human cancers: a meta-analysis. AB - Growing studies have confirmed that long non-coding RNAs (lncRNAs) involve in the occurrence and development of various cancers. XIST, as a lncRNA, was dysregulated in different cancers. This meta-analysis was performed to evaluate the prognostic potential of XIST in malignant tumors. Eight databases of PubMed, Web of Science, Embase, Cochrane library, CNKI, VIP, SinoMed and Wang Fang were comprehensively searched from their initiation date to August 15, 2017. A total of nine studies with 853 cancer patients met the including criteria were finally included in this meta-analysis after independently screening the literatures by two researchers. Any discrepancies were resolved by a consensus. Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for the primary endpoints were extracted and pooled for meta-analysis. Our results showed that expression level of XIST was markedly associated with overall survival (function as oncogene, HR = 0.53, 95% CI: 0.42-0.68, p < 0.00001; function as tumor suppressor, HR = 2.25, 95% CI: 1.15-4.37, p = 0.02), disease free survival (DFS)(HR = 0.45; 95% CI: 0.31-0.67, p < 0.0001), tumor type (digestive system carcinoma, HR = 0.50; 95% CI: 0.37-0.69, p < 0.00001; non-digestive system carcinoma, HR = 0.58; 95% CI: 0.39-0.87, p = 0.008), lymph node metastasis (OR = 0.32, 95% CI: 0.20-0.52, p < 0.00001), distant metastasis (OR = 0.36, 95% CI: 0.22-0.60, p < 0.0001) and tumor stage (OR = 0.43, 95% CI: 0.31-0.60, p < 0.00001). In conclusion, the pooled results in our current work suggest that XIST is an important prognostic biomarker in cancer patients. PMID- 29568405 TI - Prognostic value of PD-L1 in esophageal squamous cell carcinoma: a meta-analysis. AB - Accumulated evidence has shown that the programmed cell death receptor 1/programmed cell death receptor 1 ligand 1 (PD-1/PD-L1) pathway is a promising therapeutic target for cancer immunotherapy. However, the association between PD L1 and esophageal squamous cell carcinoma (ESCC) patient survival remains unclear. We performed a meta-analysis to investigate the prognostic value of PD L1 in ESCC. We searched PubMed, Embase, Web of Knowledge, and Cochrane Central Register of Controlled Trials databases for relevant studies that evaluated PD-L1 expression and ESCC patient survival. Fixed- and random-effects meta-analyses were conducted according to the heterogeneity of the included studies. Sensitivity analysis was performed according to Metan-based influence analysis. Publication bias was evaluated using Egger's and Begg's tests. Overall, 13 studies with 2,877 patients were included. Twelve studies demonstrated the association between overall survival (OS), and 6 studies described the relation between disease-free survival (DFS). PD-L1 overexpression was found in 43.7% (1,258 of 2,877) of the patients with ESCC. High PD-L1 expression was associated with distant metastasis in patients with ESCC (P = 0.04). Moreover, high PD-L1 expression was significantly associated with poor OS (hazard ratio [HR] 1.38, 95% confidence interval [CI] = 1.02-1.86, P = 0.04) and especially in Asian populations (HR 1.49, 95% CI = 1.11-1.99, P = 0.008). But it did not have an impact on disease-free survival (HR 1.15, 95% CI = 0.76-1.74, P = 0.52). Further well-designed clinical studies with uniform assessment approaches for PD-L1 expression are warranted to verify its prognostic value. PMID- 29568406 TI - Clinicopathologic and prognostic significance of C-reactive protein/albumin ratio in patients with solid tumors: an updated systemic review and meta-analysis. AB - C-reactive protein/albumin ratio (CAR) was originally used as a novel inflammation-based prognostic score in predicting outcomes in septic patients. Recently, more and more studies have reported the prognostic value of pretreatment CAR in solid tumors. However, the results remain controversial rather than conclusive. We conducted a meta-analysis based on 24 studies with 10203 patients to explore the relationship between CAR and survival outcomes in patients with solid tumors. The correlation between CAR and clinicopathological parameters was also assessed. Hazard ratio (HR) or odds ratio (OR) with its 95% confidence interval (CI) was applied to be the effect size estimate. The overall results showed that elevated CAR was associated with shorter overall survival (OS) (including 23 studies and 10067 patients) and poorer disease-free survival (DFS) (including 6 studies and 2904 patients). Significant associations between high CAR level and poor OS were also found in the subgroup analyses of study region, cancer type, primary treatment, clinical stage, cut-off selection, sample size, and cut-off value. Moreover, subgroup analyses demonstrated that study region, primary treatment, clinical stage, sample size, and cut-off value did not alter the prognostic value of CAR for DFS. Furthermore, elevated CAR was correlated with certain phenotypes of tumor aggressiveness, such as poor histological grade, serious clinical stage, advanced tumor depth, positive lymph node metastasis, and positive distant metastasis. Together, our meta-analysis suggests that elevated level of serum CAR predicts worse survival and unfavorable clinical characteristics in cancer patients, and CAR may serve as an effective prognostic factor for solid tumors. PMID- 29568407 TI - MiR-486 as an effective biomarker in cancer diagnosis and prognosis: a systematic review and meta-analysis. AB - Purpose: MiR-486 was found to be associated with cancer's diagnosis and prognosis. This meta-analysis aimed to investigate the potential effect of miR 486 on cancer detection and prognosis. Materials and Methods: We searched PubMed, Cochrane library, Embase, Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases to find all correlated articles. The STATA 11.0 was applied to estimate the pooled effects, heterogeneity and publication bias. Results: The pooled sensitivity (SEN), specificity (SPE) and Area under the curve (AUC) were 82% (95% CI: 78-85%), 88% (95% CI: 83-92%) and 0.91 (95% CI: 0.88-0.93). Subgroup analysis indicated miR-486 from circulating samples exhibited higher diagnostic accuracy with the AUC was 0.90 (95% CI: 0.87-0.92) than miR-486 from other specimen with the AUC of 0.78 (95% CI: 0.75-0.82) and miR-486 obtained a better diagnostic value in the Asian population with the AUC of 0.94 (95% CI: 0.91-0.95) than the Caucasian and Caucasian/African population with the AUC of 0.80 (95% CI: 0.76-0.83) and 0.89 (95% CI: 0.86-0.91) respectively. MiR-486 obtained high value for the diagnosis of non-small cell lung cancer with SEN, SPE and AUC were 0.82 (95% CI: 0.0.77-0.87), 0.90 (95% CI: 0.84-0.94) as well as 0.92 (95% CI: 0.89 0.94) respectively. For the 7 prognostic tests, the pooled hazard ratio (HR) was 0.48 (95% CI: -0.13-1.08) for low versus high miR-486 expression. Conclusions: This meta-analysis indicated that miR-486 can be used as ideal biomarkers in the cancer's diagnosis. However, Low miR-486 expression did not increase the risk of poor outcome. PMID- 29568408 TI - Association of body mass index with mortality and postoperative survival in renal cell cancer patients, a meta-analysis. AB - Obesity is one of the major risk factors of cancer. However, how body mass index (BMI) influences the prognosis of renal cell cancer (RCC) patient is unclear. In this work, we have performed a meta-analysis to elucidate the role of abnormal weight in RCC mortality and postoperative survival. Articles related to BMI and RCC mortality as well as postoperative survival has been identified by searching PUBMED and ENBASE. Totally, 19 articles have been selected for this meta analysis, 5 articles for RCC mortality and 14 for postoperative survival. Compared to normal weight, the estimated relative risks of RCC mortality are 0.71 (95% CI: 0.34-1.49), 1.19 (95% CI: 1.05-1.35) and 1.71 (95% CI: 1.27-2.00) respectively for the underweight, overweight and obesity patients. The risk of RCC mortality increase 5% for each 1 kg/m2 increment of BMI. However, the estimated hazard ratios of cancer specific postoperative survival are 2.62 (95% CI: 1.67-4.11), 0.72 (95% CI: 0.63-0.83) and 0.66 (95% CI: 0.49-0.89) respectively for underweight, overweight and obesity RCC patients. The risk of hazard ratio decrease 5% for each 1 kg/m2 increment of BMI. In addition, the hazard ratios of postoperative overall survival show a similar tendency. These results indicate an opposite association of BMI with mortality and postoperative survival in renal cell cancer patients. PMID- 29568409 TI - Combined value of red blood cell distribution width and global registry of acute coronary events risk score on predicting long-term major adverse cardiac events in STEMI patients undergoing primary PCI. AB - The combined value of RDW and GRACE risk score for cardiovascular prognosis in ST segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) has not been fully investigated. This study was designed to explore the combined value of RDW and GRACE risk score on predicting long-term major adverse cardiac event (Mace) in STEMI patients undergoing primary PCI. This study included 390 STEMI patients. The primary endpoint at the (33.5 +/ 7.1) months follow-up was composed of cardiac death and nonfatal myocardial infarction. The relationship between clinical parameters and clinical outcomes was evaluated using Cox regression model and receiver operating characteristic (ROC) analysis. Mace occurred in 126 (32.3%) patients including 54 (13.8%) cardiac deaths and 72 (18.5%) nonfatal myocardial infarctions. Patients in Mace group had significantly higher RDW and GRACE score than the patients in non-Mace group. According to the Cox model, RDW and GRACE score were the most important independent predictors of Mace and cardiac death. The best cut-off value for RDW to predict the occurrence of primary events was 13.25% (AUC = 0.694, 95% CI:0.639 0.750, P < 0.001) and that for GRACE score was 119.5 (AUC = 0.721, 95% CI:0.666 0.777, P < 0.001). The combination of RDW and GRACE score were more valuable (AUC = 0.775, 95% CI: 0.727-0.824, P < 0.001). Kaplan-Meier analysis provided significant prognostic information with the highest risk for cardiac death (Log Rank chi2 = 24.684, P < 0.001) in group with both high RDW (> 13.25%) and high GRACE score (> 119.5). The combination of RDW level and GRACE score may be valuable and simple independent predictors of Mace and cardiac death in STEMI patients undergoing primary PCI. They may be useful tools for risk stratification and may indicate long-term clinical outcomes. PMID- 29568410 TI - Prevalence of non-syndromic orofacial clefts: based on 15,094,978 Chinese perinatal infants. AB - Non-syndromic orofacial clefts (NSOFC), which include cleft lip and palate (CLP), cleft lip only (CLO), and cleft palate only (CPO), contains a range of disorders affecting the lips and oral cavity. No systematic review and meta-analysis has been carried out to synthesize the prevalence of NSOFC in Chinese perinatal infants. We aimed to quantify and understand the variation of prevalence national and regional levels. Four English databases and four Chinese databases were searched using a comprehensive search strategy from inception to April 2017. The random effect model was used for this meta-analysis. To determine the sources of heterogeneity, subgroup analyses and meta-regression were conducted based on different categories. The protocol has been pre-registered in the PROSPERO, number CRD42017062293. 110 studies, including 15,094,978 Chinese perinatal infants, were eligible for inclusion. The pooled prevalence rate for NSOFC was 1.670/00 (95% CI 1.53-1.82), varying with provinces. The pooled prevalence estimate was 0.560/00 (0.50-0.63) for CLO, 0.820/00 (0.73-0.90) for CLP, and 0.270/00 (0.24-0.30) for CPO. Significant associations were found between overall prevalence estimates and survey year and study region. The prevalence of NSOFC was severe in Chinese perinatal infants, varying with provinces. The results will serve as a baseline for future assessment of the overall effectiveness of NSOFC control, and will also support and inform health policy for planning and helping health debates. PMID- 29568411 TI - The development of CAR design for tumor CAR-T cell therapy. AB - In recent years, the chimeric antigen receptor modified T cells (Chimeric antigen receptor T cells, CAR-T) immunotherapy has developed rapidly, which has been considered the most promising therapy. Efforts to enhance the efficacy of CAR based anti-tumor therapy have been made, such as the improvement of structures of CAR-T cells, including the development of extracellular antigen recognition receptors, intracellular co-stimulatory molecules and the combination application of CARs and synthetic small molecules. In addition, effects on the function of the CAR-T cells that the space distance between the antigen binding domains and tumor targets and the length of the spacer domains have are also being investigated. Given the fast-moving nature of this field, it is necessary to make a summary of the development of CAR-T cells. In this review, we mainly focus on the present design strategies of CAR-T cells with the hope that they can provide insights to increase the anti-tumor efficacy and safety. PMID- 29568413 TI - Performance evaluation method for read mapping tool in clinical panel sequencing. AB - In addition to the rapid advancement in Next-Generation Sequencing (NGS) technology, clinical panel sequencing is being used increasingly in clinical studies and tests. However, tools that are used in NGS data analysis have not been comparatively evaluated in performance for panel sequencing. This study aimed to evaluate the tools used in the alignment process, the first procedure in bioinformatics analysis, by comparing tools that have been widely used with ones that have been introduced recently. With the accumulated panel sequencing data, detected variant lists were cataloged and inserted into simulated reads produced from the reference genome (h19). The amount of unmapped reads and misaligned reads, mapping quality distribution, and runtime were measured as standards for comparison. As the most widely used tools, Bowtie2 and BWA-MEM each showed explicit performance with AUC of 0.9984 and 0.9970 respectively. Kart, maintaining superior runtime and less number of misaligned read, also similarly possessed high level of AUC (0.9723). Such selection and optimization method of tools appropriate for panel sequencing can be utilized for fields requiring error minimization, such as clinical application and liquid biopsy studies. PMID- 29568414 TI - Comparative genomic analysis of Lactobacillus plantarum GB-LP4 and identification of evolutionarily divergent genes in high-osmolarity environment. AB - Lactobacillus plantarum is one of the widely-used probiotics and there have been a large number of advanced researches on the effectiveness of this species. However, the difference between previously reported plantarum strains, and the source of genomic variation among the strains were not clearly specified. In order to understand further on the molecular basis of L. plantarum on Korean traditional fermentation, we isolated the L. plantarum GB-LP4 from Korean fermented vegetable and conducted whole genome assembly. With comparative genomics approach, we identified the candidate genes that are expected to have undergone evolutionary acceleration. These genes have been reported to associate with the maintaining homeostasis, which are generally known to overcome instability in external environment including low pH or high osmotic pressure. Here, our results provide an evolutionary relationship between L. plantarum species and elucidate the candidate genes that play a pivotal role in evolutionary acceleration of GB-LP4 in high osmolarity environment. This study may provide guidance for further studies on L. plantarum. PMID- 29568415 TI - Dynamic light sheet generation and fluorescence imaging behind turbid media. AB - Background: Light sheet microscopy became a popular tool allowing fast imaging with reduced out of focus light. However, when light penetrates turbid media such as biological tissues, multiple scattering scrambles the illumination into a speckle pattern and severely challenges conventional fluorescence imaging with focused light or with a light sheet. In this article, we present generation of light sheet type illumination patterns despite scattering. Methods: We optimize the wave-front of the incoming light to transform the speckle pattern behind the scattering layer into a light sheet within the region of interest. We utilize a fast spatial light modulator for phase modulation and a genetic optimization algorithm. The light pattern behind the scattering layer is detected via a clear detection path and acts as a feedback signal for the algorithm. Results: We enabled homogenous light sheet illumination behind turbid media and enhanced the signal of fluorescent beads selectively at the desired focal plane up to eight times on average. The technique is capable to compensate the dynamic changes of the speckle pattern as well, as shown on samples consisting of living drosophila pupae. Conclusion: Our technique shows that not only single foci, but also a homogenous light sheet illumination can directly be created and maintained behind static and dynamic scattering media. To make the technique suitable for common biological settings, where the detection path is turbid as well, a fluorescent probe can be used to provide the feedback signal. PMID- 29568412 TI - Impact of physical exercise in cancer survivors during and after antineoplastic treatments. AB - Cancer patients experience symptoms and adverse effects of treatments that may last even after the end of treatments. Exercise is a safe, non-pharmacological and cost-effective therapy that can provide several health benefits in cancer patient and survivors, reducing cancer symptoms and cancer treatment side effects. The purpose of this review is to describe how the physical exercise is capable to reduce cancer symptoms and cancer treatment side effects. We realized a pragmatic classification of symptoms, dividing them into physical, psychological and psycho-physical aspects. For each symptom we discuss causes, therapies, we analyse the effects of physical exercise and we summarize the most effective type of exercise to reduce the symptoms. This review also points out what are the difficulties that patients and survivors face during the practice of physical activity and provides some solutions to overcome these barriers. Related to each specific cancer, it emerges that type, frequency and intensity of physical exercise could be prescribed and supervised as a therapeutic program, like it occurs for the type, dose and duration of a drug treatment. PMID- 29568416 TI - Does the thermal evolution of molecular structures critically affect the magnetic anisotropy? AB - A dysprosium based single-ion magnet is synthesized and characterized by the angular dependence of the single-crystal magnetic susceptibility. Ab initio and effective electrostatic analyses are performed using the molecular structures determined from single crystal X-ray diffraction at 20 K, 100 K and 300 K. Contrary to the common assumption, the results reveal that the structural thermal effects that may affect the energy level scheme and magnetic anisotropy below 100 K are negligible. PMID- 29568417 TI - Bidirectional photoswitching of magnetic properties at room temperature: ligand driven light-induced valence tautomerism. AB - Valence tautomeric (VT) metal complexes are highly promising bistable molecular compounds for applications as molecular switches in molecular electronics and spintronics. Although VT species can be switched with light, the photoswitching in all reported systems requires very low temperatures (usually below 20 K) because photoinduced states are highly unstable at room temperature. The thermal instability hinders any practical application of these complexes in genuine devices. In this report, for the first time we demonstrate photoswitching of VT species and associated magnetic properties at room temperature. The bidirectional photoswitching in solution is due to cis-trans photoisomerizable 4-styrylpyridine ligands deliberately integrated into cobalt dioxolene molecular complexes. The novel type of photoswitching has been coined Ligand-Driven Light-Induced Valence Tautomerism (LD-LIVT). The photoconversion of VT states of 28% has been achieved in solution at room temperature. The photoinduced states show extraordinary thermal stability for hours at room temperature, as compared to common nanoseconds reported previously. The switching proceeds at molecular level with the effective photoswitching rate of 3 * 1013 molecules per s under our conditions. Consequently, this work may open new horizons in applications of molecular switches based on VT metal complexes in molecular devices functioning at room temperature. PMID- 29568418 TI - Selective and sensitive visualization of endogenous nitric oxide in living cells and animals by a Si-rhodamine deoxylactam-based near-infrared fluorescent probe. AB - Nitric oxide (NO) is a fundamental signaling molecule that regulates virtually every critical cellular function, and it is also a potent mediator of cellular damage in a wide range of conditions mainly via its secondary metabolite peroxynitrite (ONOO-). In this work, we present an o-phenylenediamine (OPD) locked Si-rhodamine deoxylactam, i.e.deOxy-DALSiR, as a near-infrared fluorescent probe for the selective and sensitive detection of NO in living cells and bodies. Not only could the probe overcome the limitations suffered by widely used and commercialized OPD-type fluorescent NO probes, such as the possible interferences by dehydroascorbic acid/ascorbic acid/methylglyoxal (DHA/AA/MGO), pH-sensitive fluorescence output, and short excitation and emission wavelengths, but it can also avoid serious interference from cysteine (Cys) found in the rhodamine lactam based fluorescent NO probes developed later. What's more, the probe is fairly sensitive for NO, as evidenced by its rapid fluorescence response rate (within seconds), huge fluorescence off-on ratio (6300-fold), and ultra-low detection limit (0.12 nM). Its effectiveness and practicability have been demonstrated by the successful imaging of endogenous NO in RAW 264.7 macrophages, pancreatic beta cells, and endothelial EA.hy926 cells, as well as in inflamed and diabetic mouse models. PMID- 29568419 TI - Multifunctional (3-in-1) cancer theranostics applications of hydroxyquinoline appended polyfluorene nanoparticles. AB - The accumulation of fluorescent hydroxyquinoline-affixed polyfluorene (PF-HQ) nanoparticles and their utility for multi-color bio-imaging and drug delivery for cancer treatment are reported. The formation of nanoparticles (PF-HQ) containing hydrophobic pockets via three-dimensional growth of a polymeric backbone in a higher water fraction (THF : H2O = 1 : 9) was observed. The nanoparticles showed incredible dual-state optical and fluorescence properties, which were further explored in multi-color cell imaging in both cancer and normal cells. The cell viability assay in various normal cells confirmed the biocompatible nature of PF HQ, which was further supported by an ex vivo (chick chorioallantoic membrane assay) model. This encouraged us to fabricate PF-HQ-based new drug delivery systems (DDS: PF-HQ-DOX) upon conjugation with the FDA-approved anti-cancer drug doxorubicin (DOX) by filling the hydrophobic pockets of the polymer nanoparticles. The enhanced anti-cancer activity of the DDS (PF-HQ-DOX) compared with that of free DOX was observed in mouse melanoma cancer cells (B16F10) and a subcutaneous mouse (C57BL6/J) melanoma tumor model upon administration of PF-HQ DOX. Ex vivo biodistribution studies using a fluorescence quantification method demonstrated the enhanced accumulation of DOX in tumor tissues in the PF-HQ-DOX treated group compared to that of the free drug, signifying the drug delivery efficacy of the delivery system by a passive targeting manner. Based on the above biological data (in vitro and in the pre-clinical model), these robust and versatile fluorescent hydroxyquinoline-affixed polyfluorene (PF-HQ) nanoparticles could be effectively utilized for multifunctional biomedical applications (as they are biocompatible and can be used for bio-imaging and as a drug delivery vehicle). PMID- 29568420 TI - Achieving enhanced cell penetration of short conformationally constrained peptides through amphiphilicity tuning. AB - Due to their enhanced stability and cell permeability, cyclic cell-penetrating peptides have been widely used as delivery vectors for transporting cell impermeable cargos into cells. In this study, we synthesized a panel of conformationally constrained peptides with either alpha-helix or beta-hairpin conformations. We tuned the amphiphilicity of these constrained peptides with different distributions of charged or hydrophobic residues and compared their cellular uptake efficiencies in different cell lines. We found that the amphipathicity of these conformationally constrained peptides correlates well with their cellular uptake efficiency. We proposed that peptides with larger hydrophobic moments (HMs) have stronger binding affinities with the cell membrane which further accelerates the endocytosis process. This finding should provide an approach towards the design of more potent conformationally constrained cell penetrating peptides for biomedical applications. PMID- 29568421 TI - Simultaneous quantification of multiple endogenous biothiols in single living cells by plasmonic Raman probes. AB - Intracellular biothiols mediate many important physiological and pathological processes. Due to their low content and competing thiol-reactivity, it is still an unmet challenge to quantify them within a complicated intracellular environment. Herein, we demonstrated a strategy to discriminate three biothiols, i.e. cysteine (Cys), homo-cysteine (Hcy) and glutathione (GSH), and quantify their concentrations within single living cells, using one platform of Raman probe. By monitoring the reaction kinetics of biothiols with Raman probes and discriminating their products with a quantitative principal component analysis (qPCA) method, these three biothiols could be simultaneously quantified in both cell lysis and single living cells. The concentrations of Cys, Hcy and GSH in single Hela cells were 158 +/- 19 MUM, 546 +/- 67 MUM and 5.07 +/- 0.62 mM, respectively, which gives the precise concentrations of these three biothiols at a single cell level for the first time. This method provides a general strategy for discriminating each component from a mixed system and has potential for quantifying any biomolecules within an in vitro or in vivo biological environment. PMID- 29568422 TI - Michael addition-based probes for ratiometric fluorescence imaging of protein S depalmitoylases in live cells and tissues. AB - The reversible modification of cysteine residues through thioester formation with palmitate (protein S-palmitoylation) is a prevalent chemical modification that regulates the function, localization, and stability of many proteins. Current methods for monitoring the "erasers" of S-palmitoylation, acyl-protein thioesterases (APTs), rely on destructive proteomic methods or "turn-on" probes, precluding deployment in heterogeneous samples such as primary tissues. To address these challenges, we present the design, synthesis, and biological evaluation of Ratiometric Depalmitoylation Probes (RDPs). RDPs respond to APTs with a robust ratiometric change in fluorescent signal both in vitro and in live cells. Moreover, RDPs can monitor endogenous APT activities in heterogeneous primary human tissues such as colon organoids, presaging the utility of these molecules in uncovering novel roles for APTs in metabolic regulation. PMID- 29568423 TI - An acidic pH independent piperazine-TPE AIEgen as a unique bioprobe for lysosome tracing. AB - Lysosomes are involved in a multitude of cellular processes and their dysfunction is associated with various diseases. They are the most acidic organelles (pH 3.8 6.6, size 0.1-1.2 MUm) with the highest viscosity (47-190 cP at 25 degrees C) in the cell. Because of their acidity, pH dependent non-AIE active fluorescent lysosomal probes have been developed that rely on protonation inhibited photoinduced electron transfer (PET). In this work, an acidic pH independent lysosome targetable piperazine-TPE (PIP-TPE) AIEgen has been designed with unique photophysical properties making it a suitable probe for quantifying viscosity. In a non-aggregated state PIP-TPE shows deep-blue emission as opposed to its yellowish-green emission in the bulk. It possesses high specificity for lysosomes with negligible cytotoxicity and good tracing ability due to its better photostability compared to LysoTracker Red. In contrast to most known lysosome probes that rely solely on PET, restriction of intramolecular motion (RIM) due to the larger viscosity inside the lysosomes is the mechanism responsible for PIP TPE's fluorescence. PIP-TPE's high selectivity is attributed to its unique molecular design that features piperazine fragments providing a perfect balance between lipophilicity and polarity. PMID- 29568424 TI - Optical control of GPR40 signalling in pancreatic beta-cells. AB - Fatty acids activate GPR40 and K+ channels to modulate beta-cell function. Herein, we describe the design and synthesis of FAAzo-10, a light-controllable GPR40 agonist based on Gw-9508. FAAzo-10 is a potent GPR40 agonist in the trans configuration and can be inactivated on isomerization to cis with UV-A light. Irradiation with blue light reverses this effect, allowing FAAzo-10 activity to be cycled ON and OFF with a high degree of spatiotemporal precision. In dissociated primary mouse beta-cells, FAAzo-10 also inactivates voltage-activated and ATP-sensitive K+ channels, and allows us to control glucose-stimulated Ca2+ oscillations in whole islets with light. As such, FAAzo-10 is a useful tool to study the complex effects, with high specificity, which FA-derivatives such as Gw 9508 exert at multiple targets in mouse beta-cells. PMID- 29568425 TI - A functionalized metal-organic framework decorated with O- groups showing excellent performance for lead(ii) removal from aqueous solution. AB - Heavy metal ions are highly toxic and widely spread as environmental pollutants. New strategies are being developed to efficiently remove these toxic ions. Herein, we use the intrinsic advantages of metal-organic frameworks (MOFs) and develop a porous Zn(ii)-based MOF decorated with O- groups for the removal of Pb2+. Benefiting from its multiple porosity, sufficient adsorption sites and strong affinity, the activated MOF material exhibits an ultrahigh Pb2+ uptake capacity (616.64 mg g-1), surpassing all those of reported MOF adsorbents. Moreover, it can selectively capture Pb2+ with high efficiency (>99.27%) against background ions. Even in the presence of a high concentration of competitive ions, such as Ca2+ or Mg2+, effective removal (>99.21%) can also be achieved in a short time. The excellent removal performance demonstrates the strong electrostatic attraction and coordination interaction between the highly accessible O- groups and Pb2+. The possible adsorption mechanism was systematically verified by zeta potential, FT-IR and XPS studies. Our work reveals the enormous potential of functionalized MOFs as an appealing platform to construct sorbent materials. PMID- 29568426 TI - Towards quantifying the role of hydrogen bonding within amphiphile self association and resultant aggregate formation. AB - Herein, we present a series of five tetrabutylammonium (TBA) sulfonate-urea amphiphilic salts. In solution these amphiphilic salts have been shown to form a variety of self-associated species. The proportion and type of which are both solvent and concentration dependent. In DMSO-d6 a variety of NMR experiments provide evidence towards the formation of mainly dimeric over larger aggregate species. Increasing the percentage of water was shown to increase the concentration of the larger aggregates over dimers in solution. A correlation was established between critical micelle concentration (CMC) values obtained in a 1 : 19 EtOH : H2O mixture, dimeric self-association constants obtained in a DMSO-d6 - 0.5% H2O and the results of simple semi-empirical PM6 computational modelling methods. This approach begins to quantify the role of hydrogen bonding in amphiphile self-association and the effects it imparts on surfactant properties. This consequently provides preliminary evidence that these properties maybe predicted by simple low level computational modelling techniques. PMID- 29568427 TI - Nanomolar small-molecule detection using a genetically encoded 129Xe NMR contrast agent. AB - Genetically encoded magnetic resonance imaging (MRI) contrast agents enable non invasive detection of specific biomarkers in vivo. Here, we employed the hyper CEST 129Xe NMR technique to quantify maltose (32 nM to 1 mM) through its modulation of conformational change and xenon exchange in maltose binding protein (MBP). Remarkably, no hyper-CEST signal was observed for MBP in the absence of maltose, making MBP an ultrasensitive "smart" contrast agent. The resonance frequency of 129Xe bound to MBP was greatly downfield-shifted (Deltadelta = 95 ppm) from the 129Xe(aq) peak, which facilitated detection in E. coli as well as multiplexing with TEM-1 beta-lactamase. Finally, a Val to Ala mutation at the MBP Xe binding site yielded 34% more contrast than WT, with 129Xe resonance frequency shifted 59 ppm upfield from WT. We conclude that engineered MBPs constitute a new class of genetically encoded, analyte-sensitive molecular imaging agents detectable by 129Xe NMR/MRI. PMID- 29568429 TI - Intramolecular substitution uncages fluorogenic probes for detection of metallo carbapenemase-expressing bacteria. AB - This work reports a novel caging strategy for designing fluorogenic probes to detect the activity of beta-lactamases. The caging strategy uses a thiophenyl linker connected to a fluorophore caged by a good leaving group-dinitrophenyl. The uncaging proceeds in two steps through the sulfa-releasing and subsequent intramolecular substitution. The length of the linker has been examined and optimized to maximize the rate of intramolecular reaction and thus the rate of fluorescence activation. Finally based on this strategy, we prepared a green fluorogenic probe CAT-7 and validated its selectivity for detecting metallo carbapenemases (VIM-27, IMP-1, NDM-1) in carbapenem-resistant Enterobacteriaceae (CRE) lysates. PMID- 29568428 TI - Formylation or methylation: what determines the chemoselectivity of the reaction of amine, CO2, and hydrosilane catalyzed by 1,3,2-diazaphospholene? AB - DFT computations have been performed to gain insight into the mechanisms of formylation/methylation of amines (e.g. methylaniline (1a)/2,2,4,4 tetramethylpiperidine (2a)) with CO2 and hydrosilane ([Si]H2, [Si] = Ph2Si), catalyzed by 1,3,2-diazaphospholene ([NHP]H). Different from the generally proposed sequential mechanism for the methylation of amine with CO2, i.e. methylation proceeds via formylation, followed by further reduction of formamide to give an N-methylated amine, the study characterized a competition mechanism between formylation and methylation. The chemoselectivity originates from the competition between the amine and [NHP]H hydride to attack the formyloxy carbon of [Si](OCHO)2 (the insertion product of CO2 into [Si]H2). When the attack of an amine (e.g.1a) wins, the transformation affords formamide (1b) but would otherwise (e.g.2a) result in an N-methylated amine (2c). The reduction of formamide by [Si]H2 or [NHP]H is highly unfavorable kinetically, thus we call attention to the sequential mechanism for understanding the methylation of amine with CO2. In addition, the study has the following key mechanistic findings. The activation of CO2 by [NHP]H establishes an equilibrium: [NHP]H + CO2 ? [NHP]OCHO ? [NHP]+ + HCO2-. The ions play catalytic roles to promote formylation via HCO2- or methylation via[NHP]+ . In 1a formylation, HCO2- initiates the reaction, giving 1b and silanol byproducts. However, after the initiation, the silanol byproducts acting as hydrogen transfer shuttles are more effective than HCO2- to promote formylation. In 2a methylation, [NHP]+ promotes the generation of the key species, formaldehyde and a carbocation species (IM17+ ). Our experimental study corroborates our computed mechanisms. PMID- 29568430 TI - Selective inhibition of cancer cells by enzyme-induced gain of function of phosphorylated melittin analogues. AB - The selective killing of cancer cells and the avoidance of drug resistance are still difficult challenges in cancer therapy. Here, we report a new strategy that uses enzyme-induced gain of function (EIGF) to regulate the structure and function of phosphorylated melittin analogues (MelAs). Original MelAs have the capacity to disrupt plasma membranes and induce cell death without selectivity. However, phosphorylation of Thr23 on one of the MelAs (MelA2-P) efficiently ameliorated the membrane lysis potency as well as the cytotoxicity for normal mammalian cells. After treatment with alkaline phosphatase (ALP), which is more active in cancer cells than normal cells, MelA2-P restored the pore-forming function around the cancer cells and induced cancer cell death selectively. This mechanism was independent of the receptor proteins and the cell uptake process, which may partially bypass the development of drug resistance in cancer cells. PMID- 29568431 TI - Electrochemical recognition and quantification of cytochrome c expression in Bacillus subtilis and aerobe/anaerobe Escherichia coli using N,N,N',N' tetramethyl-para-phenylene-diamine (TMPD). AB - The colorimetric identification of pathogenic and non-pathogenic bacteria in cell culture is commonly performed using the redox mediator N,N,N',N'-tetramethyl-para phenylene-diamine (TMPD) in the so-called oxidase test, which indicates the presence of bacterial cytochrome c oxidases. The presented study demonstrates the ability of electrochemistry to employ TMPD to detect bacteria and quantify the activity of bacterial cytochrome c oxidases. Cyclic voltammetry studies and chronoamperometry measurements performed on the model organism Bacillus subtilis result in a turnover number, calculated for single bacteria. Furthermore, trace amounts of cytochrome c oxidases were revealed in aerobically cultured Escherichia coli, which to our knowledge no other technique is currently able to quantify in molecular biology. The reported technique could be applied to a variety of pathogenic bacteria and has the potential to be employed in future biosensing technology. PMID- 29568432 TI - Addressing the autofluorescence issue in deep tissue imaging by two-photon microscopy: the significance of far-red emitting dyes. AB - The fluorescence imaging of tissue is essential for studying biological events beyond the cellular level. Two-photon microscopy based on the nonlinear light absorption of fluorescent dyes is a viable tool for the high resolution imaging of tissue. A key limitation for deep tissue imaging is the autofluorescence from intrinsic biomolecules. Here, we report a systematic study that discloses relative autofluorescence interference, which is dependent on the type of tissue and the excitation and emission wavelengths in two-photon imaging. Among the brain, kidney, liver, lung, and spleen mouse tissues examined, the kidney tissue exhibited prominent autofluorescence followed by the liver and others. Notably, regardless of the tissue type, prominent autofluorescence is observed not only from the green emission channel but also from the yellow emission channel where common two-photon absorbing dyes also emit, whereas there is minimal autofluorescence from the red channel. The autofluorescence is slightly influenced by the excitation wavelength. Toward minimal autofluorescence, we developed a new class of two-photon absorbing dyes that are far-red emitting, water-soluble, and very bright inside cells as well as in tissue. A comparative assessment of the imaging depth, which is dependent on the three selected dyes that emit in the blue-green, yellow, and far-red regions, shows the importance of far-red emitting dyes for deep tissue imaging. PMID- 29568433 TI - Synthetic upcycling of polyacrylates through organocatalyzed post-polymerization modification. AB - The direct transformation of commercially available commodity polyacrylates into value-added materials was achieved. We demonstrate how 1,5,7 triazabicyclo[4.4.0]dec-5-ene, serving as a nucleophilic catalyst, can be used to catalyze acyl substitution reactions of acrylic polymers in the presence of alcohol and amine nucleophiles. Furthermore, we found that organocatalytic transesterification exhibits high selectivity towards sterically unhindered esters, thus providing a new route towards site-selective acyl substitution of macromolecular materials. Combining this methodology with reversible-deactivation radical polymerization (RDRP) techniques such as reversible addition fragmentation chain-transfer (RAFT) polymerization allowed for the precise functionalization of sterically-differentiated acrylic copolymers and polymeric chain ends. We envision this approach to expedite functional polymer synthesis and provide access to functional macromolecules prepared from inexpensive, hydrolytically-stable polymeric precursors. PMID- 29568434 TI - Tuning the stereo-hindrance of a curcumin scaffold for the selective imaging of the soluble forms of amyloid beta species. AB - Amyloid peptides and proteins are associated with the pathologies of numerous diseases. In the progression of a disease, amyloids exist in soluble and insoluble forms, which are the dominant species at different stages of the disease and they have different degrees of toxicity. However, differentiating between the soluble and insoluble forms is very challenging with small molecule probes due to multiple obstacles that need to be overcome. Inspired by the recognition principle of antibodies for sAbeta, we hypothesized that the accessibility/tightness of soluble and insoluble amyloids could be utilized to design imaging probes to recognize different amyloid forms and the stereo hindrance tuning strategy could be used to design imaging probes for selectively detecting the soluble amyloid beta (sAbeta) species in Alzheimer's disease (AD). Herein, we demonstrated that tuning the stereo-hindrance of the phenoxy-alkyl chains at the 4-position of a curcumin scaffold could lead to certain selectivity for sAbeta over insoluble Abetas (insAbeta). Among the designed compounds, CRANAD 102 showed a 68-fold higher affinity for sAbeta than for insAbeta (7.5 +/- 10 nM vs. 505.9 +/- 275.9 nM). Moreover, our imaging data indicated that CRANAD-102 was indeed capable of detecting sAbeta in vivo using 4 month old APP/PS1 mice, in which sAbeta is the predominant species in the brain. In addition, we also demonstrated that CRANAD-102 could be used to monitor the increase in sAbeta loading from the ages of 4 months old to 12 months old. We believe that CRANAD 102 can be a useful probe for selectively detecting sAbeta species in AD and that our probe designing strategy can be applied to other amyloids and will have tremendous impact on AD drug development and other amyloid research. PMID- 29568435 TI - Influence of axle length on the rate and mechanism of shuttling in rigid H-shaped [2]rotaxanes. AB - A series of [2]rotaxane molecular shuttles was prepared containing a dibenzo[24]crown-8 (DB24C8) wheel and a rigid H-shaped axle with varying track lengths between recognition sites; from 7.4 to 20.3 A as defined by 1-4 phenyl rings or a naphthyl group. The rate of shuttling was measured by variable temperature 1H NMR spectroscopy for neutral compounds and EXSY experiments for dicationic species. The rates were found to be independent of the length of the axle, except when the distance between the two recognition sites might be short enough (n = 1) to allow the crown ether to simultaneously interact with both recognition sites providing a short-cut mechanism which could lower the energy barrier. This notion is supported by DFT calculations and solid-state characterization of model compounds that mimic possible transition states. PMID- 29568436 TI - A structural examination and collision cross section database for over 500 metabolites and xenobiotics using drift tube ion mobility spectrometry. AB - The confident identification of metabolites and xenobiotics in biological and environmental studies is an analytical challenge due to their immense dynamic range, vast chemical space and structural diversity. Ion mobility spectrometry (IMS) is widely used for small molecule analyses since it can separate isomeric species and be easily coupled with front end separations and mass spectrometry for multidimensional characterizations. However, to date IMS metabolomic and exposomic studies have been limited by an inadequate number of accurate collision cross section (CCS) values for small molecules, causing features to be detected but not confidently identified. In this work, we utilized drift tube IMS (DTIMS) to directly measure CCS values for over 500 small molecules including primary metabolites, secondary metabolites and xenobiotics. Since DTIMS measurements do not need calibrant ions or calibration like some other IMS techniques, they avoid calibration errors which can cause problems in distinguishing structurally similar molecules. All measurements were performed in triplicate in both positive and negative polarities with nitrogen gas and seven different electric fields, so that relative standard deviations (RSD) could be assessed for each molecule and structural differences studied. The primary metabolites analyzed to date have come from key metabolism pathways such as glycolysis, the pentose phosphate pathway and the tricarboxylic acid cycle, while the secondary metabolites consisted of classes such as terpenes and flavonoids, and the xenobiotics represented a range of molecules from antibiotics to polycyclic aromatic hydrocarbons. Different CCS trends were observed for several of the diverse small molecule classes and when urine features were matched to the database, the addition of the IMS dimension greatly reduced the possible number of candidate molecules. This CCS database and structural information are freely available for download at http://panomics.pnnl.gov/metabolites/ with new molecules being added frequently. PMID- 29568437 TI - Mechanically induced pyrogallol[4]arene hexamer assembly in the solid state extends the scope of molecular encapsulation. AB - Pyrogallol[4]arene hexamers are hydrogen-bonded molecular capsules of exceptional kinetic stability that can entrap small molecule guests indefinitely, without exchange, at ambient temperatures. Here, we report on the use of a ball mill to induce self-assembly of the capsule components and the guests in the solid state. Stoichiometric amounts of pyrogallol[4]arene and a guest, which can be an arene, alkane, amine, or carboxylic acid, were milled at 30 Hz for fixed durations, dissolved, and characterization by NMR. Most of the resulting encapsulation complexes were kinetically stable but thermodynamically unstable in solution, and the yield of their formation correlates with the duration of the milling and is related to the structures of guest and host. This method extends the scope of molecular encapsulation, as demonstrated by the preparation of kinetically trapped encapsulation complexes of [2.2]paracyclophane, for which we could find no other method of preparation. To gain mechanistic insights into the solid-state assembly process, we characterized the milled powders using 13C CP-MAS NMR, we studied the effects of changing the alkane domain of the host, and we examined how dissolution conditions impact on the distribution of observed encapsulation complexes once in solution. The results support a mechanism comprising mechanically induced solid-state reorganization to produce a mixture rich in nearly or fully assembled guest-filled capsules.

An aryl-extended tetraaldehyde calix[4]pyrrole scaffold was condensed with suitable diamines as linkers using templates for efficient self-assembly. The capsular complexes were characterized in solution, gas phase and the solid-state. Unprecedented transfer of asymmetry was observed from a chiral diamine linker to the resulting supramolecular capsular assembly.

We first introduce the existing approaches for flexible LED fabrication, which are dominated by organic technologies, and we briefly discuss the increasing research effort on flexible inorganic LEDs achieved by micro-structuring and transfer of conventional thin films. Then, flexible nanowire-based LEDs are presented and two main fabrication technologies are discussed: direct growth on a flexible substrate and nanowire membrane formation and transfer. The performance of blue, green, white and bi-color flexible LEDs fabricated following the transfer approach is discussed in more detail. PMID- 29568441 TI - The significance of bromide in the Brust-Schiffrin synthesis of thiol protected gold nanoparticles. AB - The mechanism of the two-phase Brust-Schiffrin synthesis of alkane thiol protected metal nanoparticles is known to be highly sensitive to the precursor species and reactant conditions. In this work X-ray absorption spectroscopy is used in conjunction with liquid/liquid electrochemistry to highlight the significance of Br- in the reaction mechanism. The species [AuBr4]- is shown to be a preferable precursor in the Brust-Schiffrin method as it is more resistant to the formation of Au(i) thiolate species than [AuCl4]-. Previous literature has demonstrated that avoidance of the Au(i) thiolate is critical to achieving a good yield of nanoparticles, as [Au(i)X2]- species are more readily reduced by NaBH4. We propose that the observed behavior of [AuBr4]- species described herein explains the discrepancies in reported behavior present in the literature to date. This new mechanistic understanding should enable nanoparticle synthesis with a higher yield and reduce particle size polydispersity. PMID- 29568440 TI - Chemoenzymatic synthesis of heparan sulfate and heparin oligosaccharides and NMR analysis: paving the way to a diverse library for glycobiologists. AB - Heparan sulfate (HS) is a member of the glycosaminoglycans (GAG) family that plays essential roles in biological processes from animal sources. Heparin, a highly sulfated form of HS, is widely used as anticoagulant drug worldwide. The high diversity and complexity of HS and heparin represent a roadblock for structural characterization and biological activity studies. Access to structurally defined oligosaccharides is critical for the successful development of HS and heparin structure-activity relationships. In this study, a library of 66 HS and heparin oligosaccharides covering different sulfation patterns and sizes was prepared through an efficient method of chemoenzymatic synthesis. A systematic nuclear magnetic resonance spectroscopy study was firstly undertaken for every oligosaccharide in the library. In addition to the availability of different oligosaccharides, this work also provides spectroscopic data helpful for characterizing more complicated polysaccharide structures providing a safeguard to ensure the quality of the drug heparin. This HS/heparin library will be useful for activity screening and facilitate future structure-activity relationship studies.

Using rhodium catalysis, linear beta-enaminone products are generated in high yield and excellent regioselectivity from the combination of aldehydes and ynamides. The enaminone products are subsequently used as a platform to construct a diverse array of substituted pyrazoles, pyrimidines, and isoxazoles in a two-step, one pot sequence. It was found that with judicious choice of catalyst system it was possible to overturn the regioselectivity of the hydroacylation reaction to generate alpha-enaminone products. PMID- 29568443 TI - A modular route to boron doped PAHs by combining borylative cyclisation and electrophilic C-H borylation. AB - Heteroatom doping into polyaromatic hydrocarbons (PAHs) is a powerful approach for modifying key physical properties, however, there are extremely few modular routes that enable facile formation of B-, B2- and B,N-(specifically not containing direct B-N bonds) doped PAHs despite the growing importance of these materials. Sequential, one pot borylative cyclisation/intramolecular electrophilic C-H borylation of naphthyl-alkynes provides a simple new route to access novel B-, B,N- and B2-doped (PAHs). The initial products, dihydronaphthalene/dihydroquinoline B-mesityl PAHs, were reacted with [Ph3C][BF4]/pyridyl base to form the oxidised B-, and B,N-doped PAHs. However, for B-triisopropylphenyl (Trip) PAH congeners oxidation has to be performed prior to Trip installation due to preferential oxidation of an isopropylaryl moiety to the styrene. This alternative sequence enables access to Trip-B-PAHs and to structurally constrained B and B2-PAHs. Analysis of the solid state structures and optoelectronic properties of these PAHs confirm that frontier orbital energies, extended packing structures, Stokes shift and quantum yields all can be rationally modified using this methodology. The simplicity of this synthetic approach makes it a powerful tool for rapidly generating novel bench stable boron doped PAHs, which is important for facilitating further structure-property relationship studies and the wider utilisation of these materials in optoelectronic applications.

AB - A tetradentate Pd(ii) complex, Pd3O3, which exhibits highly efficient excimer emission is synthesized and characterized. Pd3O3 can achieve blue emission despite using phenyl-pyridine emissive ligands which have been a mainstay of stable green and red phosphorescent emitter designs, making Pd3O3 a good candidate for stable blue or white OLEDs. Pd3O3 exhibits strong and efficient phosphorescent excimer emission expanding the excimer based white OLEDs beyond the sole class of Pt complexes. Devices of Pd3O3 demonstrate peak external quantum efficiencies as high as 24.2% and power efficiencies of 67.9 Lm per W for warm white devices. Furthermore, Pd3O3 devices in a carefully designed stable structure achieved a device operational lifetime of nearly 3000 h at 1000 cd m-2 without any outcoupling enhancement while simultaneously achieving peak external quantum efficiencies of 27.3% and power efficiencies over 81 Lm per W.

AB - Creative strategies for identifying new antibiotics are essential to addressing the looming threat of a post-antibiotic era. We here report the use of a targeted peptide phage display screen as a means of generating novel antimicrobial lipopeptides. Specifically, a library of phage displayed bicyclic peptides was screened against a biomolecular target based on the bacterial cell wall precursor lipid II. In doing so we identified unique lipid II binding peptides that upon lipidation were found to be active against a range of Gram-positive bacteria including clinically relevant strains of vancomycin resistant bacteria. Optimization of the peptide sequence led to variants with enhanced antibacterial activity and reduced hemolytic activity. Biochemical experiments further confirm a lipid II mediated mode of action for these new-to-nature antibacterial lipopeptides.

AB - The internal free volume of porous materials diminishes upon mechanical compression, and such volume collapse can have chemical consequences. We report here the endothermic bond breakage in a metal-organic framework (MOF) during compression-induced collapse. Upon bulk compression at 1.9 GPa, the effective number for Zr-O bonds between Zr(iv) ions and carboxylate groups in UiO-66 decreased from 4.0 to 1.9, as determined by EXAFS, and the internal free volume was synchronously collapsed. Consistent with the EXAFS data, IR spectra confirmed conversion of syn-syn bridging carboxylates to monodentate ligation, thus establishing mechanochemical reactions induced by external compression of MOFs. Substantial mechanical energy (~4 kJ g-1) was absorbed by UiO-66 nanocrystals during compression, as demonstrated from nanocompression of single crystals (600 nm) in situ during scanning electron microscopy, which establishes the potential application of MOFs as mechanical energy absorbers for hydrostatic and shock compression.

AB - Unveiling the detailed roles of glutathione (GSH) in chemoresistance necessitates a reliable assay for its detection in intact live specimens. Herein, by taking advantage of the susceptibility of electron-poor Csp2 -Ssufinyl bond to GSH nucleophilic attack, we developed a naphthalimide-sulfoxide based fluorogenic probe (Na-8) applicable for tracking endogenous GSH fluctuation in live cells. Na 8 features a high degree of sensitivity towards GSH as demonstrated by its utmost 2200-fold fluorogenic response. As a proof of concept, Na-8 has been applied to image GSH in liver cancer HepG2 cells with the normal L02 cell counterparts serving as a control, and elevated GSH level was observed in HepG2 in contrast to L02. Further experiments showed that this elevated GSH level was involved in doxorubicin-resistance but not in cisplatin-resistance. Noteworthy, monitoring GSH change in HepG2 and L02 cells in response to doxorubicin treatment revealed that while normal cells showed a burst of GSH in adaption to doxorubicin treatment, no significant change was detected in HepG2 cells, suggesting that HepG2 cells have been preconditioned by their intrinsic oxidative stress which confers drug-resistance. Given the observed sensitivity and spatiotemporal resolution, Na-8 should hold promise for future study on the detailed roles of GSH in drug-resistance.

AB - Cell behaviors are known to be regulated by the cellular microenvironment. Traditional cell-population based analysis methods need to separate cells from their extracellular matrix (ECM) and cannot resolve the heterogeneity of cell behaviors. Herein, an in situ single-cell analysis method based on rolling circle amplification was exploited to image gene expression in single cells for investigating the effect of ECM stiffness on cell growth. This method enables the simultaneous quantifying of the cell phenotype and gene expression at the single cell level, which can help in understanding the underlying molecular mechanism of cell growth. It is found that ECM stiffness could affect cell growth via regulating the expression level of the cytoskeleton-assembly associated genes PFN1 and CFL1 and their co-expression pattern. Therefore, this single-cell analysis platform may facilitate us to tap into the study of "single-cell phenotypes" and elucidate the disease association of ECMs. PMID- 29568450 TI - Integration of intracellular telomerase monitoring by electrochemiluminescence technology and targeted cancer therapy by reactive oxygen species. AB - Cancer therapies based on reactive oxygen species (ROS) have emerged as promising clinical treatments. Electrochemiluminescence (ECL) technology has also attracted considerable attention in the field of clinical diagnosis. However, studies about the integration of ECL diagnosis and ROS cancer therapy are very rare. Here we introduce a novel strategy that employs ECL technology and ROS to fill the above vacancy. Briefly, an ITO electrode was electrodeposited with polyluminol-Pt NPs composite films and modified with aptamer DNA to capture HL-60 cancer cells with high specificity. After that, mesoporous silica nanoparticles (MSNs) filled with phorbol 12-myristate 13-acetate (PMA) were closed by the telomerase primer DNA (T primer DNA) and aptamer. After aptamer on MSN@PMA recognized and combined with the HL-60 cancer cells with high specificity, T-primer DNA on MSN@PMA could be moved away from the MSN@PMA surface after extension by telomerase in the HL-60 cancer cells and PMA was released to induce the production of ROS by the HL-60 cancer cells. After that, the polyluminol-Pt NPs composite films could react with hydrogen peroxide (a major ROS) and generate an ECL signal. Thus the intracellular telomerase activity of the HL-60 cancer cells could be detected in situ. Besides, ROS could induce apoptosis in the HL-60 cancer cells with high efficacy by causing oxidative damage to the lipids, protein, and DNA. Above all, the designed platform could not only detect intracellular telomerase activity instead of that of extracted telomerase, but could also kill targeted tumors by ECL technology and ROS.

AB - A new type-I clathrate, Ba8Cu14Ge6P26, was synthesized by solid-state methods as a polycrystalline powder and grown as a cm-sized single crystal via the vertical Bridgman method. Single-crystal and powder X-ray diffraction show that Ba8Cu14Ge6P26 crystallizes in the cubic space group Pm3n (no. 223). Ba8Cu14Ge6P26 is the first representative of anionic clathrates whose framework is composed of three atom types of very different chemical natures: a transition metal, tetrel element, and pnicogen. Uniform distribution of the Cu, Ge, and P atoms over the framework sites and the absence of any superstructural or local ordering in Ba8Cu14Ge6P26 were confirmed by synchrotron X-ray diffraction, electron diffraction and high-angle annular dark field scanning transmission electron microscopy, and neutron and X-ray pair distribution function analyses. Characterization of the transport properties demonstrate that Ba8Cu14Ge6P26 is a p-type semiconductor with an intrinsically low thermal conductivity of 0.72 W m-1 K-1 at 812 K. The thermoelectric figure of merit, ZT, for a slice of the Bridgman grown crystal of Ba8Cu14Ge6P26 approaches 0.63 at 812 K due to a high power factor of 5.62 MUW cm-1 K-2. The thermoelectric efficiency of Ba8Cu14Ge6P26 is on par with the best optimized p-type Ge-based clathrates and outperforms the majority of clathrates in the 700-850 K temperature region, including all tetrel free clathrates. Ba8Cu14Ge6P26 expands clathrate chemistry by bridging conventional tetrel-based and tetrel-free clathrates. Advanced transport properties, in combination with earth-abundant framework elements and congruent melting make Ba8Cu14Ge6P26 a strong candidate as a novel and efficient thermoelectric material.

AB - Single-molecule magnets (SMMs) are considered viable candidates for next generation data storage and quantum computing. Systems featuring switchability of their magnetization dynamics are particularly interesting with respect to accessing more complex logic gates and device architectures. Here we show that transition metal based redox events can be exploited to enable reversible switchability of slow magnetic relaxation of magnetically anisotropic lanthanide ions. Specifically, we report anionic homoleptic bis-diamidoferrocene complexes of Dy3+ (oblate) and Er3+ (prolate) which can be reversibly oxidized by one electron to yield their respective charge neutral redox partners (Dy: [1]- , 1; Er: [2]- , 2). Importantly, compounds 1 and 2 are thermally stable which allowed for detailed studies of their magnetization dynamics. We show that the Dy3+[1]- /1 system can function as an "on"/"off" or a "slow"/"fast" redox switchable SMM system in the absence or presence of applied dc fields, respectively. The Er3+ based [2]- /2 system features "on"/"off" switchability of SMM properties in the presence of applied fields. Results from electrochemical investigations, UV-vis NIR spectroscopy, and 57Fe Mossbauer spectroscopy indicate the presence of significant electronic communication between the mixed-valent Fe ions in 1 and 2 in both solution and solid state. This comparative evaluation of redox-switchable magnetization dynamics in low coordinate lanthanide complexes may be used as a potential blueprint toward the development of future switchable magnetic materials. PMID- 29568454 TI - Identification of catabolite control protein A from Staphylococcus aureus as a target of silver ions. AB - Staphylococcus aureus is one of the most common pathogenic bacteria that causes human infectious diseases. The emergence of antibiotic-resistant strains of S. aureus promotes the development of new anti-bacterial strategies. Silver ions (Ag+) have attracted profound attention due to their broad-spectrum antimicrobial activities. Although the antibacterial properties of silver have been well known for many centuries, its mechanism of action remains unclear and its protein targets are rarely reported. Herein, we identify the catabolite control protein A (CcpA) of S. aureus as a putative target for Ag+. CcpA binds 2 molar equivalents of Ag+via its two cysteine residues (Cys216 and Cys242). Importantly, Ag+ binding induces CcpA oligomerization and abolishes its DNA binding capability, which further attenuates S. aureus growth and suppresses alpha-hemolysin toxicity. This study extends our understanding of the bactericidal effects of silver. PMID- 29568453 TI - A thiocyanopalladation/carbocyclization transformation identified through enzymatic screening: stereocontrolled tandem C-SCN and C-C bond formation. AB - Herein we describe a formal thiocyanopalladation/carbocyclization transformation and its parametrization and optimization using a new elevated temperature plate based version of our visual colorimetric enzymatic screening method for reaction discovery. The carbocyclization step leads to C-SCN bond formation in tandem with C-C bond construction and is highly stereoselective, showing nearly absolute 1,2 anti-stereoinduction (5 examples) for substrates bearing allylic substitution, and nearly absolute 1,3-syn-stereoinduction (16 examples) for substrates bearing propargylic substitution. Based upon these high levels of stereoinduction, the dependence of the 1,2-stereoinduction upon cyclization substrate geometry, and the generally high preference for the transoid vinyl thiocyanate alkene geometry, a mechanistic model is proposed, involving (i) Pd(ii)-enyne coordination, (ii) thiocyanopalladation, (iii) migratory insertion and (iv) beta-elimination. Examples of transition metal-mediated C-SCN bond formation that proceed smoothly on unactivated substrates and allow for preservation of the SCN moiety are lacking. Yet, the thiocyanate functionality is of great value for biophysical chemistry (vibrational Stark effect) and medicinal chemistry (S,N-heterocycle construction). The title transformation accommodates C-, O-, N- and S-bridged substrates (6 examples), thereby providing the corresponding carbocyclic or heterocyclic scaffolds. The reaction is also shown to be compatible with a significant range of substituents, varying in steric and electronic demand, including a wide range of substituted aromatics, fused bicyclic and heterocyclic systems, and even biaryl systems. Combination of this new transformation with asymmetric allylation and Grubbs ring-closing metathesis provides for a streamlined enantio- and diastereoselective entry into the oxabicyclo[3.2.1]octyl core of the natural products massarilactone and annuionone A, as also evidenced by low temperature X-ray crystal structure determination. Utilizing this bicyclic scaffold, we demonstrate the versatility of the thiocyanate moiety for structural diversification post-cyclization. Thus, the bridging vinyl thiocyanate moiety is smoothly elaborated into a range of derivative functionalities utilizing transformations that cleave the S-CN bond, add the elements of RS-CN across a pi system and exploit the SCN moiety as a cycloaddition partner (7 diverse examples). Among the new functionalities thereby generated are thiotetrazole and sulfonyl tetrazole heterocycles that serve as carboxylate and phosphate surrogates, respectively, highlighting the potential of this approach for future applications in medicinal chemistry or chemical biology.

AB - Multifunctional polymer-inorganic Janus nanoparticles (JNPs) that simultaneously have therapeutic and imaging functions are highly desired in biomedical applications. Here, we fabricated spherical polydopamine/mesoporous calcium phosphate hollow JNPs (PDA/mCaP H-JNPs) via a novel and facile approach. The obtained PDA/mCaP H-JNPs were further selectively functionalized with indocyanine green (ICG) and methoxy-poly(ethylene glycol)thiol (PEG-SH) on PDA domains to achieve a superior photoacoustic (PA) imaging capability and stability, while the other mCaP sides with hollow cavities served as storage spaces and passages for the anti-cancer drug, doxorubicin (DOX). The resultant PEG-ICG-PDA/mCaP H-JNPs possess excellent biocompatibility, a competent drug loading capability, high photothermal conversion efficiency, strong near-infrared (NIR) absorbance, and pH/NIR dual-responsive properties, enabling the H-JNPs to be applied for PA imaging-guided synergistic cancer chemo-phototherapy in vitro and in vivo. Furthermore, the synthetic approach could be extended to prepare PDA/various mesoporous inorganic H-JNPs with spherical shapes for specific applications. PMID- 29568456 TI - Bis(aminothiolato)nickel nanosheet as a redox switch for conductivity and an electrocatalyst for the hydrogen evolution reaction. AB - A pi-conjugated coordination nanosheet comprising bis(aminothiolato)nickel (NiAT) moieties was synthesized by the reaction of Ni(acac)2 with 1,3,5-triaminobenzene 2,4,6-trithiol at liquid-liquid and gas-liquid interfaces. The sheet thickness could be controlled down to a single layer (0.6 nm). Selected area electron diffraction and grazing incidence X-ray diffraction analyses indicated the formation of a flat crystalline sheet with a kagome lattice stacked in a staggered alignment. NiAT was reversibly interconverted to a bis(iminothiolato)nickel (NiIT) nanosheet by the chemical 2H+-2e- reaction, which was accompanied by a drastic change in electrical conductivity from 3 * 10-6 to 1 * 10-1 S cm-1. This change in conductivity was explained by the difference in band structures between NiAT and NiIT. NiAT acted as an efficient electrocatalyst for the hydrogen evolution reaction, showing strong acid durability and an onset overpotential of -0.15 V. PMID- 29568457 TI - Enantioselective synthesis of cyclopenta[b]benzofurans via an organocatalytic intramolecular double cyclization. AB - An enantioselective organocatalytic strategy, combining Bronsted base and N heterocyclic carbene catalysis in a unique manner, is demonstrated for a concise construction of the privileged cyclopenta[b]benzofuran scaffold, present in many bioactive compounds having both academic and commercial interests. The reaction concept relies on an intramolecular one-pot double cyclization involving a cycle specific enantioselective Michael addition followed by a benzoin condensation of ortho-substituted cinnamaldehydes. Cyclopenta[b]benzofurans were achieved in moderate to good yields, with excellent stereoselectivities. A proof of principle for a diastereodivergent variation is demonstrated through the synthesis of cyclopenta[b]benzofurans containing two contiguous aromatic substituents in a substitution pattern present in commercial and natural compounds. Furthermore, several transformations have been performed, demonstrating the synthetic utility of the products. Finally, insights into the activation mode and stereoindution models are presented for this new synthetic strategy. PMID- 29568458 TI - Ex situ generation of stoichiometric HCN and its application in the Pd-catalysed cyanation of aryl bromides: evidence for a transmetallation step between two oxidative addition Pd-complexes. AB - A protocol for the Pd-catalysed cyanation of aryl bromides using near stoichiometric and gaseous hydrogen cyanide is reported for the first time. A two chamber reactor was adopted for the safe liberation of ex situ generated HCN in a closed environment, which proved highly efficient in the Ni-catalysed hydrocyanation as the test reaction. Subsequently, this setup was exploited for converting a range of aryl and heteroaryl bromides (28 examples) directly into the corresponding benzonitriles in high yields, without the need for cyanide salts. Cyanation was achieved employing the Pd(0) precatalyst, P(tBu)3-Pd-G3 and a weak base, potassium acetate, in a dioxane-water solvent mixture. The methodology was also suitable for the synthesis of 13C-labelled benzonitriles with ex situ generated 13C-hydrogen cyanide. Stoichiometric studies with the metal complexes were undertaken to delineate the mechanism for this catalytic transformation. Treatment of Pd(P(tBu)3)2 with H13CN in THF provided two Pd hydride complexes, (P(tBu)3)2Pd(H)(13CN), and [(P(tBu)3)Pd(H)]2Pd(13CN)4, both of which were isolated and characterised by NMR spectroscopy and X-ray crystal structure analysis. When the same reaction was performed in a THF : water mixture in the presence of KOAc, only (P(tBu)3)2Pd(H)(13CN) was formed. Subjection of this cyano hydride metal complex with the oxidative addition complex (P(tBu)3)Pd(Ph)(Br) in a 1 : 1 ratio in THF led to a transmetallation step with the formation of (P(tBu)3)2Pd(H)(Br) and 13C-benzonitrile from a reductive elimination step. These experiments suggest the possibility of a catalytic cycle involving initially the formation of two Pd(ii)-species from the oxidative addition of L n Pd(0) into HCN and an aryl bromide followed by a transmetallation step to L n Pd(Ar)(CN) and L n Pd(H)(Br), which both reductively eliminate, the latter in the presence of KOAc, to generate the benzonitrile and L n Pd(0). PMID- 29568459 TI - Oligomers of cyclopentadithiophene-vinylene in aromatic and quinoidal versions and redox species with intermediate forms. AB - A new series of pi-conjugated oligomers based on the 4,4 dihexyl-4H cyclopenta[2,1-b:3,4-b']dithiophene vinylene repeating unit has been prepared and characterized by X-ray, electrochemical, spectroscopic (UV-Vis absorption, emission and Raman) and density functional theory methods. The oligomers in their neutral, oxidized and reduced forms have been investigated. The neutral compounds show a longer mean conjugation length than oligothiophenes and oligothiophene vinylenes and display very rich redox chemistry with the stabilization of polycationic states of which the radical cations and dications are strong NIR absorbers, the latter displaying singlet diradicaloid character. An interesting complementarity between the sequence of aromatic-quinoidal structural segments in the radical cations and dications has been described and interpreted. Two derivatives with the 4,4 dihexyl-4H-cyclopenta[2,1-b:3,4-b']dithiophene vinylene unit, disubstituted either with electron donor, bis(triaryl amino) groups, or acceptors bis(dicyano-methylene) caps enforcing a quinoidal structure in the dithiophene-vinylene bridge, have been also synthesized and characterized. The radical cation of the triarylamine compound and the radical anion of the tetracyano compound similarly display hole and electron charge localization, or confinement, in the nitrogen and dicyano surrounding parts, or class II mixed valence systems, while their dication and dianion species, conversely, are open shell diradical (i.e., polaron pair) and closed-shell (i.e., bipolaron), respectively. The preparation of these new pi-conjugated oligomers gives way to the realization of compounds with new electronic properties and unique structures potentially exploitable in organic electronics. PMID- 29568460 TI - HOMO inversion as a strategy for improving the light-absorption properties of Fe(ii) chromophores. AB - A computational study of a series of [Fe(tpy)2]2+ (tpy = 2,2':6',2''-terpyridine) complexes is reported, where the tpy ligand is substituted at the 4, 4', and 4'' positions by electron donor (furan, thiophene, selenophene, NH2) and acceptor (carboxylic acid, NO2) groups. Using DFT and TD-DFT calculations, we show that the substitution of heterocyclic pi donor groups onto the tpy ligand scaffold leads to marked improvement of the [Fe(tpy)2]2+ absorption properties, characterized by increased molar extinction coefficients, shift of absorption energies to longer wavelengths, and broadening of the absorption spectrum in the visible region. The observed changes in the light absorption properties are due to destabilization of ligand-centered occupied pi orbital energies, thus increasing the interactions between the metal t2g (HOMO) and ligand pi orbitals. Substitution of extended pi-conjugated groups, such as thienothiophene and dithienothiophene, further destabilizes the ligand pi orbital energies, resulting in a fully ligand-localized HOMO (i.e., HOMO inversion) and additional improvement of the light absorption properties. These results open up a new strategy to tuning the light absorption properties of Fe(ii)-polypyridines. PMID- 29568461 TI - Influence of the [4Fe-4S] cluster coordinating cysteines on active site maturation and catalytic properties of C. reinhardtii [FeFe]-hydrogenase. AB - [FeFe]-Hydrogenases catalyze the evolution and oxidation of hydrogen using a characteristic cofactor, termed the H-cluster. This comprises an all cysteine coordinated [4Fe-4S] cluster and a unique [2Fe] moiety, coupled together via a single cysteine. The coordination of the [4Fe-4S] cluster in HydA1 from Chlamydomonas reinhardtii was altered by single exchange of each cysteine (C115, C170, C362, and C366) with alanine, aspartate, or serine using site-directed mutagenesis. In contrast to cysteine 115, the other three cysteines were found to be dispensable for stable [4Fe-4S] cluster incorporation based on iron determination, UV/vis spectroscopy and electron paramagnetic resonance. However, the presence of a preformed [4Fe-4S] cluster alone does not guarantee stable incorporation of the [2Fe] cluster. Only variants C170D, C170S, C362D, and C362S showed characteristic signals for an inserted [2Fe] cluster in Fourier-transform infrared spectroscopy. Hydrogen evolution and oxidation were observed for these variants in solution based assays and protein-film electrochemistry. Catalytic activity was lowered for all variants and the ability to operate in either direction was also influenced. PMID- 29568462 TI - Simple organic structure directing agents for synthesizing nanocrystalline zeolites. AB - The synthesis of the ZSM-5 and beta zeolites in their nanosized form has been achieved by using simple alkyl-substituted mono-cationic cyclic ammonium cations as OSDA molecules. The particular combination of a cyclic fragment and a short linear alkyl-chain group (preferentially C4) within the monocationic OSDA molecules allows directing the crystallization of nanosized zeolites with excellent solid yields (above 90%). Interestingly, the formation of the nanosized ZSM-5 and beta zeolites mostly depends on the size and nature of the cyclic fragment of the OSDA molecule, resulting in all cases in nanocrystalline solids with homogeneous distributions of particle sizes (~10-25 nm) and controlled Si/Al molar ratios (~15-30). The achieved nanosized ZSM-5 and beta zeolites have been extensively characterized by different techniques to study their physico-chemical properties, such as chemical composition, pore accessibility or Bronsted acidity, among others. Moreover, the catalytic properties of the nanosized ZSM-5 and beta zeolites have been evaluated for different chemical reactions, including methanol to-olefins (MTO) in the case of ZSM-5, and alkylation of benzene with propylene to obtain cumene and oligomerization of light olefins to liquid fuels in the case of beta, observing in all cases improved catalytic activity and product selectivity towards target products when compared to related catalysts.

AB - The benzodiselenazoles (BDS) introduced in this report fulfill, for the first time, all the prerequisites for non-covalent high-precision chalcogen-bonding catalysis in the focal point of conformationally immobilized sigma holes on strong selenium donors in a neutral scaffold. Rational bite-angle adjustment to the long Se-C bonds was the key for BDS design. For the unprecedented BDS motif, synthesis of 12 analogs from o-xylene, crystal structure, sigma hole variation strategies, optoelectronic properties, theoretical and experimental anion binding as well as catalytic activity are reported. Chloride binding increases with the depth of the sigma holes down to KD = 11 MUM in THF. Catalytic activities follow the same trend and culminate in rate enhancements for transfer hydrogenation of quinolines beyond 100 000. PMID- 29568464 TI - Evolved polymerases facilitate selection of fully 2'-OMe-modified aptamers. AB - RNA or DNA aptamers with 2'-OMe-modifications have been pursued to increase resistance to nucleases, but have been difficult to identify because the OMe groups ablate polymerase recognition. We recently reported evolution of the thermostable DNA polymerases SFM4-6 and SFM4-9, which enable the efficient "transcription" and "reverse transcription", respectively, of 2'-OMe oligonucleotides. With these polymerases, we now report the first selection of fully 2'-OMe modified aptamers, specifically aptamers that bind human neutrophil elastase (HNE). Two aptamers, 2mHNE-1 and 2mHNE-2, were isolated after five rounds of selection, and four more, 2mHNE-3-6, after an additional five rounds that included selection pressure for binding in the presence of serum. All six aptamers bind with reasonable affinity, which requires the 2'-OMe substituents. Further characterization of one aptamer, 2mHNE-5, showed that unlike a previously reported natural anti-HNE aptamer, affinity for HNE is retained in the presence of high concentrations of salt or serum. The polymerases SFM4-6 and SFM4-9 should prove valuable for the production and further exploration of modified aptamers. PMID- 29568465 TI - Teixobactin analogues reveal enduracididine to be non-essential for highly potent antibacterial activity and lipid II binding. AB - Teixobactin is a highly promising antibacterial depsipeptide consisting of four d amino acids and a rare l-allo-enduracididine amino acid. l-allo-Enduracididine is reported to be important for the highly potent antibacterial activity of teixobactin. However, it is also a key limiting factor in the development of potent teixobactin analogues due to several synthetic challenges such as it is not commercially available, requires a multistep synthesis, long and repetitive couplings (16-30 hours). Due to all these challenges, the total synthesis of teixobactin is laborious and low yielding (3.3%). In this work, we have identified a unique design and developed a rapid synthesis (10 min MUwave assisted coupling per amino acid, 30 min cyclisation) of several highly potent analogues of teixobactin with yields of 10-24% by replacing the l-allo enduracididine with commercially available non-polar residues such as leucine and isoleucine. Most importantly, the Leu10-teixobactin and Ile10-teixobactin analogues have shown highly potent antibacterial activity against a broader panel of MRSA and Enterococcus faecalis (VRE). Furthermore, these synthetic analogues displayed identical antibacterial activity to natural teixobactin (MIC 0.25 MUg mL-1) against MRSA ATCC 33591 despite their simpler design and ease of synthesis. We have confirmed lipid II binding and measured the binding affinities of individual amino acid residues of Ala10-teixobactin towards geranyl pyrophosphate by NMR to understand the nature and strength of binding interactions. Contrary to current understanding, we have shown that a cationic amino acid at position 10 is not essential for target (lipid II) binding and potent antibacterial activity of teixobactin. We thus provide strong evidence contrary to the many assumptions made about the mechanism of action of this exciting new antibiotic. Introduction of a non-cationic residue at position 10 allows for tremendous diversification in the design and synthesis of highly potent teixobactin analogues and lays the foundations for the development of teixobactin analogues as new drug-like molecules to target MRSA and Mycobacterium tuberculosis.

AB - Natural availability of carbonyl groups offers reductive carbonyl coupling tremendous synthetic potential for efficient olefin synthesis, yet the catalytic carbonyl cross-coupling remains largely elusive. We report herein such a reaction, mediated by hydrazine under ruthenium(ii) catalysis. This method enables facile and selective cross-couplings of two unsymmetrical carbonyl compounds in either an intermolecular or intramolecular fashion. Moreover, this chemistry accommodates a variety of substrates, proceeds under mild reaction conditions with good functional group tolerance, and generates stoichiometric benign byproducts. Importantly, the coexistence of KO t Bu and bidentate phosphine dmpe is vital to this transformation. PMID- 29568467 TI - The alpha-tertiary amine motif drives remarkable selectivity for Pd-catalyzed carbonylation of beta-methylene C-H bonds. AB - The selective C-H carbonylation of methylene bonds in the presence of traditionally more reactive methyl C-H and C(sp2)-H bonds in alpha-tertiary amines is reported. The exceptional selectivity is driven by the bulky alpha tertiary amine motif, which we hypothesise orientates the activating C-H bond proximal to Pd in order to avoid an unfavourable steric clash with a second alpha tertiary amine on the Pd centre, promoting preferential cyclopalladation at the methylene position. The reaction tolerates a range of structurally interesting and synthetically versatile functional groups, delivering the corresponding beta lactam products in good to excellent yields.

AB - Well-defined and fully characterized supported CO2 reduction catalysts are developed through the immobilization of an earth abundant Mn complex on bpy-PMO (bpy = bipyridine; PMO = Periodic Mesoporous Organosilica) platform materials. The resulting isolated Mn-carbonyl centers coordinated to bipyridine functionalities of bpy-PMO catalyze the photoreduction of CO2 into CO and HCOOH with up to ca. 720 TON in the presence of BIH (1,3-dimethyl-2-phenyl-2,3-dihydro 1H-benzoimidazole), used as the electron donor. A broad range of photochemical conditions (varying solvents, sacrificial electron donors, photosensitizer type and concentration, catalyst loading as well as the Mn loading within the PMO) are investigated, demonstrating high activity even for simple organic dyes and Zn porphyrin as photosensitizers. Spectroscopic and catalytic data also indicate that site isolation of the Mn complex in the PMO framework probably inhibits bimolecular processes such as dimerisation and disproportionation and thus allows the spectroscopic observation of key reaction intermediates, namely the two meridional isomers of the carbonyl complexes and the bipyridine radical anion species. PMID- 29568469 TI - Supramolecular assembly affording a ratiometric two-photon fluorescent nanoprobe for quantitative detection and bioimaging. AB - Fluorescence quantitative analyses for vital biomolecules are in great demand in biomedical science owing to their unique detection advantages with rapid, sensitive, non-damaging and specific identification. However, available fluorescence strategies for quantitative detection are usually hard to design and achieve. Inspired by supramolecular chemistry, a two-photon-excited fluorescent supramolecular nanoplatform (TPSNP) was designed for quantitative analysis with three parts: host molecules (beta-CD polymers), a guest fluorophore of sensing probes (Np-Ad) and a guest internal reference (NpRh-Ad). In this strategy, the TPSNP possesses the merits of (i) improved water-solubility and biocompatibility; (ii) increased tissue penetration depth for bioimaging by two-photon excitation; (iii) quantitative and tunable assembly of functional guest molecules to obtain optimized detection conditions; (iv) a common approach to avoid the limitation of complicated design by adjustment of sensing probes; and (v) accurate quantitative analysis by virtue of reference molecules. As a proof-of-concept, we utilized the two-photon fluorescent probe NHS-Ad-based TPSNP-1 to realize accurate quantitative analysis of hydrogen sulfide (H2S), with high sensitivity and good selectivity in live cells, deep tissues and ex vivo-dissected organs, suggesting that the TPSNP is an ideal quantitative indicator for clinical samples. What's more, TPSNP will pave the way for designing and preparing advanced supramolecular sensors for biosensing and biomedicine.

AB - Catalytic synthesis of substituted 1,2-dihydronaphthalenes via metalloradical activation of o-styryl N-tosyl hydrazones ((E)-2-(prop-1-en-1-yl)benzene-N-tosyl hydrazones) is presented, taking advantage of the intrinsic reactivity of a cobalt(iii)-carbene radical intermediate. The method has been successfully applied to a broad range of substrates with various R1 substituents at the aromatic ring, producing the desired ring products in good to excellent isolated yields for substrates with an R2 = COOEt substituent at the vinylic position (~70 90%). Changing the R2 moiety from an ester to other substituents has a surprisingly large influence on the (isolated) yields. This behaviour is unexpected for a radical rebound ring-closure mechanism, and points to a mechanism proceeding via ortho-quinodimethane (o-QDM) intermediates. Furthermore, substrates with an alkyl substituent on the allylic position reacted to form E aryl-dienes in excellent yields, rather than the expected 1,2 dihydronaphthalenes. This result, combined with the outcome of supporting DFT calculations, strongly points to the release of reactive o-QDM intermediates from the metal centre in all cases, which either undergo a 6pi-cyclisation step to form the 1,2-dihydronaphthalenes, or a [1,7]-hydride shift to produce the E-aryl dienes. Trapping experiments using TEMPO confirm the involvement of cobalt(iii) carbene radical intermediates. EPR spectroscopic spin-trapping experiments using phenyl N-tert-butylnitrone (PBN) confirm the radical nature of the catalytic reaction.

AB - Organophosphorus(iii) compounds usually take on stable pyramidal structures with a large inversion barrier of 30-35 kcal mol-1. In contrast, diphenylphosphine fused Ni(ii) porphyrin, where the phosphorus atom is directly attached at the meso-position and embedded in a rigid skeleton, exhibits a considerably planarized phosphorus center. Here we report the synthesis of a mesityl substituted Ni(ii) porphyrin analogue, 6, which allowed an evaluation of the inversion barrier (DeltaG?203) by variable temperature 1H NMR spectroscopy which showed it to be exceptionally small, at 14.0 kcal mol-1. The observed small inversion barrier has been attributed to conformational constraint imposed by the fused structure. In addition, it was thought that the planar transition state is stabilized by the Ni(ii) porphyrin network that allows the contribution of a 22pi aromatic circuit involving phosphorus lone-pair electrons. Along this postulate, we attempted to engineer diarylphosphine-fused porphyrins with smaller inversion barriers by replacing the fused benzene rings with five-membered heterocyclic rings such as thiophene, benzothiophene, benzofuran, indole, benzothiophene 1,1 dioxide, and thiophene 1,1-dioxide. In that order, the aromatic character of the heterocycle decreases, which leads to increasing contribution of the 22pi aromatic circuit. Actually, the inversion barrier of the phosphorus center becomes smaller in this order and reaches 8.7 kcal mol-1 for thiophene 1,1 dioxide-fused Ni(ii) porphyrin 15, supporting the postulate. PMID- 29568472 TI - Biomimetic inorganic camouflage circumvents antibody-dependent enhancement of infection. AB - Pre-existing antibodies can aggravate disease during subsequent infection or vaccination via the mechanism of antibody-dependent enhancement (ADE) of infection. Herein, using dengue virus (DENV) as a model, we present a versatile surface-camouflage strategy to obtain a virus core-calcium phosphate shell hybrid by self-templated biomineralization. The shelled DENV stealthily avoids recognition by pre-existing antibodies under extracellular conditions, resulting in the efficient abrogation of the ADE of infection both in vitro and in vivo. Moreover, the nanoshell can spontaneously degrade under intracellular conditions to restore the virus activity and immunogenicity due to its pH-sensitive behaviour. This work demonstrates that the biomimetic material shell can significantly improve the administration safety and potency of the DENV vaccine, which provides the promising prospect of chemically designed virus-material hybrids for immune evasion. PMID- 29568473 TI - Amyloid beta-peptides 1-40 and 1-42 form oligomers with mixed beta-sheets. AB - Two main amyloid-beta peptides of different length (Abeta40 and Abeta42) are involved in Alzheimer's disease. Their relative abundance is decisive for the severity of the disease and mixed oligomers may contribute to the toxic species. However, little is know about the extent of mixing. To study whether Abeta40 and Abeta42 co-aggregate, we used Fourier transform infrared spectroscopy in combination with 13C-labeling and spectrum calculation and focused on the amide I vibration, which is sensitive to backbone structure. Mixtures of monomeric labeled Abeta40 and unlabeled Abeta42 (and vice versa) were co-incubated for ~20 min and their infrared spectrum recorded. The position of the main 13C-amide I' band shifted to higher wavenumbers with increasing admixture of 12C-peptide due to the presence of 12C-amides in the vicinity of 13C-amides. The results indicate that Abeta40 and Abeta42 form mixed oligomers with a largely random distribution of Abeta40 and Abeta42 strands in their beta-sheets. The structures of the mixed oligomers are intermediate between those of the pure oligomers. There is no indication that one of the peptides forces the backbone structure of its oligomers on the other peptide when they are mixed as monomers. We also demonstrate that isotope-edited infrared spectroscopy can distinguish aggregation modulators that integrate into the backbone structure of their interaction partner from those that do not. As an example for the latter case, the pro inflammatory calcium binding protein S100A9 is shown not to incorporate into the beta-sheets of Abeta42.

AB - A copper-catalyzed aminoalkynylation of alkenes is achieved with ethynylbenziodoxolone (EBX) reagents under mild conditions with only 1 mol% copper catalyst. This transformation allows for rapid construction of diverse important azahetereocycles and installation of valuable alkyne groups in one step. The developed method features remarkable substrate scope for both terminal and internal alkenes as well as different alkynyl groups, presenting great potential for broad applications in synthesis, bioconjugation, and molecular imaging. PMID- 29568475 TI - Mitochondria-targeted spin-labelled luminescent iridium anticancer complexes. AB - Mitochondria generate energy but malfunction in many cancer cells, hence targeting mitochondrial metabolism is a promising approach for cancer therapy. Here we have designed cyclometallated iridium(iii) complexes, containing one TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) spin label [C43H43N6O2Ir1.PF6] (Ir TEMPO1) and two TEMPO spin labels [C52H58N8O4Ir1.PF6] (Ir-TEMPO2). Electron paramagnetic resonance (EPR) spectroscopy revealed spin-spin interactions between the TEMPO units in Ir-TEMPO2. Both Ir-TEMPO1 and Ir-TEMPO2 showed bright luminescence with long lifetimes (ca. 35-160 ns); while Ir-TEMPO1 displayed monoexponential decay kinetics, the biexponential decays measured for Ir-TEMPO2 indicated the presence of more than one energetically-accessible conformation. This observation was further supported by density functional theory (DFT) calculations. The antiproliferative activity of Ir-TEMPO2 towards a range of cancer cells was much greater than that of Ir-TEMPO1, and also the antioxidant activity of Ir-TEMPO2 is much higher against A2780 ovarian cancer cells when compared with Ir-TEMPO1. Most notably Ir-TEMPO2 was particularly potent towards PC3 human prostate cancer cells (IC50 = 0.53 MUM), being ca. 8* more active than the clinical drug cisplatin, and ca. 15* more selective towards cancer cells versus normal cells. Confocal microscopy showed that both Ir-TEMPO1 and Ir-TEMPO2 localise in the mitochondria of cancer cells. PMID- 29568476 TI - Manipulating energy transfer in lanthanide-doped single nanoparticles for highly enhanced upconverting luminescence. AB - Energy transfer (ET) is of fundamental importance in tuning the optical performance of lanthanide-doped upconversion nanoparticles (UCNPs). However, the fine control and manipulation of the ETs particularly for deleterious cross relaxation type ETs (CR-ETs) in lanthanide-doped UCNPs remains a formidable challenge to date. Herein, we demonstrate a rational design strategy to manipulate the deleterious CR-ETs in lanthanide-doped UCNPs, by fine-tuning the distances at an extremely large length scale (>20 nm) among multiple lanthanide dopants that are simultaneously embedded into one single nanoparticle with specially designed multilayer nanostructures. The successful inhibition of the CR ETs leads to a significantly enhanced upconversion luminescence signal with an intensity ~70 times higher than that of co-doped conventional UCNPs. This finding paves a new way for the better control of the ETs in lanthanide-doped nanoparticles, and offers the possibility of constructing a series of promising single-nanocrystal-based anti-counterfeiting barcodes with well-identified UC emission color and lifetime outputs. PMID- 29568477 TI - MD simulations and QM/MM calculations show that single-site mutations of cytochrome P450BM3 alter the active site's complexity and the chemoselectivity of oxidation without changing the active species. AB - It is a long-standing mechanistic consensus that the mutation of the proton shuttle mediator Threonine (T) in Cytochrome P450 enzymes severs the water channel and thereby quenches the formation of the active species: the high-valent iron(iv)-oxo porphyrin pi-cation radical species, compound I (Cpd I). Using MD simulations and hybrid QM/MM calculations of P450BM3 we demonstrate that this is not the case. Thus, while the original water channel is disrupted in the T268A mutant of the enzyme, a new channel is formed that generates Cpd I. With this new understanding, we address the puzzling regiochemical and kinetic-isotope effect (KIE) results (Volz et al., J. Am. Chem. Soc., 2002, 124, 9724-9725) on the sulfoxidation and N-dealkylation of dimethyl-(4-methylsulfanyl-phenyl)-amine by wild type (WT) P450BM3 and its T268A vs. F87A mutants. We show that the observed variable ratio of S/Me oxidation for these enzymes, vis-a-vis the constant KIE, originates from Cpd I being the sole oxidant. Thus, while the conserved KIE probes the conserved nature of the transition state, the variable regiochemical S/Me ratio reflects the active-site reorganization in the mutants: the shifted location of the new water channel in T268A tightens the binding of the S-end by Cpd I and increases the S/Me ratio, whereas the absence of pi-interaction with the S-end in F87A creates a looser binding that lowers the S/Me ratio. Our results match the experimental findings. As such, this study sheds light on puzzling experimental results, and may shift a central paradigm in P450 research. The broader implication on enzymatic research is that a single-site mutation is not a localised alteration but one that may lead to a profound change in the active site, sufficiently so as to change the chemoselectivity of catalyzed reactions. PMID- 29568478 TI - Toward a patient-specific tissue engineered vascular graft. AB - Integrating three-dimensional printing with the creation of tissue-engineered vascular grafts could provide a readily available, patient-specific, autologous tissue source that could significantly improve outcomes in newborns with congenital heart disease. Here, we present the recent case of a candidate for our tissue-engineered vascular graft clinical trial deemed ineligible due to complex anatomical requirements and consider the application of three-dimensional printing technologies for a patient-specific graft. We 3D-printed a closed disposable seeding device and validated that it performed equivalently to the traditional open seeding technique using ovine bone marrow-derived mononuclear cells. Next, our candidate's preoperative imaging was reviewed to propose a patient-specific graft. A seeding apparatus was then designed to accommodate the custom graft and 3D-printed on a commodity fused deposition modeler. This exploratory feasibility study represents an important proof of concept advancing progress toward a rationally designed patient-specific tissue-engineered vascular graft for clinical application. PMID- 29568479 TI - Embryonic lethality is not sufficient to explain hourglass-like conservation of vertebrate embryos. AB - Background: Understanding the general trends in developmental changes during animal evolution, which are often associated with morphological diversification, has long been a central issue in evolutionary developmental biology. Recent comparative transcriptomic studies revealed that gene expression profiles of mid embryonic period tend to be more evolutionarily conserved than those in earlier or later periods. While the hourglass-like divergence of developmental processes has been demonstrated in a variety of animal groups such as vertebrates, arthropods, and nematodes, the exact mechanism leading to this mid-embryonic conservation remains to be clarified. One possibility is that the mid-embryonic period (pharyngula period in vertebrates) is highly prone to embryonic lethality, and the resulting negative selections lead to evolutionary conservation of this phase. Here, we tested this "mid-embryonic lethality hypothesis" by measuring the rate of lethal phenotypes of three different species of vertebrate embryos subjected to two kinds of perturbations: transient perturbations and genetic mutations. Results: By subjecting zebrafish (Danio rerio), African clawed frog (Xenopus laevis), and chicken (Gallus gallus) embryos to transient perturbations, namely heat shock and inhibitor treatments during three developmental periods [early (represented by blastula and gastrula), pharyngula, and late], we found that the early stages showed the highest rate of lethal phenotypes in all three species. This result was corroborated by perturbation with genetic mutations. By tracking the survival rate of wild-type embryos and embryos with genetic mutations induced by UV irradiation in zebrafish and African clawed frogs, we found that the highest decrease in survival rate was at the early stages particularly around gastrulation in both these species. Conclusion: In opposition to the "mid-embryonic lethality hypothesis," our results consistently showed that the stage with the highest lethality was not around the conserved pharyngula period, but rather around the early period in all the vertebrate species tested. These results suggest that negative selection by embryonic lethality could not explain hourglass-like conservation of animal embryos. This highlights the potential contribution of alternative mechanisms such as the diversifying effect of positive selections against earlier and later stages, and developmental constraints which lead to conservation of mid-embryonic stages. PMID- 29568480 TI - The Importance of Assessing Nutritional Status to Ensure Optimal Recovery during the Chronic Phase of Stroke. AB - Background: Despite evidence that many of the consequences of stroke that hinder recovery (i.e., obesity, muscle atrophy, and functional declines) have nutritionally modifiable behavior components, little attention has been focused on the significance of nutrition beyond the acute phase of stroke. Objective: This literature review summarizes the evidence for and against the influence of nutrition on optimal recovery and rehabilitation in chronic (>6 months) stroke. Results: The literature, which is mainly limited to cross-sectional studies, suggests that a suboptimal nutritional status, including an excess caloric intake, reduced protein intake, and micronutrient deficiencies, particularly the B-vitamins, vitamin D, and omega 3 fatty acids, may have deleterious effects on metabolic, physical, and psychological functioning in chronic stroke survivors. Conclusions: Careful evaluation of dietary intake, especially among those with eating disabilities and preexisting malnutrition, may aid in the identification of individuals at increased nutritional risk through which early intervention may benefit recovery and rehabilitation and prevent further complications after stroke. PMID- 29568481 TI - Impaired Inflammatory Response to LPS in Type 2 Diabetes Mellitus. AB - Type 2 diabetes mellitus (T2DM) is a severe health problem worldwide, reaching epidemic levels. High susceptibility to infections of T2DM patients indicates dysregulated immune responses to pathogens. However, innate immune responses, including monocyte functions, in T2DM are poorly investigated. Therefore, in this study we aimed to assess lipopolysaccharide- (LPS-) induced immune responses of circulating monocytes from T2DM patients. The results showed that monocytes from T2DM were hyporesponsive to LPS challenge as reflected by significantly suppressed secretion of TNFalpha (p < 0.01) and expression of CD11b (p < 0.001) and TLR4 (p < 0.001) compared to those in monocytes from healthy subjects. Furthermore, LPS-induced IL-10 levels were similar in diabetic and healthy supernatants, while expression levels of CD163 were found to be downregulated on monocytes from T2DM (p < 0.001) suggesting impaired ability of monocytes to switch their phenotype to anti-inflammatory. Taken together, our results suggest compromised function of monocytes in T2DM, which may explain, at least partly, high incidence of infection in these patients. PMID- 29568483 TI - Transplantation of endothelial progenitor cells attenuated paraquat-induced acute lung injury via miR-141-3p-Notch-Nrf2 axis. AB - Background: Paraquat (PQ) presents with high toxicity for humans and animals, and the lungs become the main target organ by the poisoning of PQ leading to acute lung injury. Endothelial progenitor cells (EPCs) were proved to have the repair function on acute lung injury (ALI). We aimed to invatigate the underlying mechanism of EPCs in PQ-induced ALI involving miR-141-3p. Methods: Endothelial progenitor cells were isolated from peripheral blood of C57BL/6J mice and identified by flow cytometry. Lung wet-to-dry (W/D) weight ratios, lung injury score and the number of total leukocyte and the number of neutrophils in BALF were used to analyze the degree of lung injury. The transfection was performed with Lipofectamine 2000. The levels of miRNA and mRNA were determined by qRT-PCR, and the protein levels were detected by Western blot assay. Results: Endothelial progenitor cells alleviated lung wet-to-dry (W/D) weight ratios, lung injury score and the number of total leukocyte and the number of neutrophils in BALF in PQ-induced ALI mice. EPCs inhibited miR-141-3p expression, and enhanced the levels of Notch-Nrf2 axis in PQ-induced ALI mice. MiR-141-3p knockdown reversed the PQ induced-inhibition on Notch-1 and Hesr1 expression. MiR-141-3p over expression could inhibit the expression of Notch-1 pathway significantly in the pulmonary epithelial cell line MLE-12. Both miR-141-3p over-expression and si Notch-1 abolished the protection effect of EPCs on lung injury induced by PQ in vivo. Conclusions: Endothelial progenitor cells could provide therapeutic effect on PQ-induced ALI via miR-141-3p-Notch-Nrf2 Axis. PMID- 29560252 TI - Rheumatoid arthritis in an adult patient with mosaic distal 18q-, 18p- and ring chromosome 18. AB - Ring chromosome 18 has a highly variable phenotype, depending on the extent of distal arm deletions. It is most commonly presented as a combination of 18p- and distal 18q- syndrome. IgA deficiency and autoimmune diseases have been previously described in these patients. Seven cases of juvenile rheumatoid arthritis (JRA) have been reported. Here we report the first case of late onset rheumatoid arthritis (RA) in a 32 year old Dominican woman with hypothyroidism, vitiligo, IgA deficiency, interstitial lung disease (ILD), cystic bronchiectasis, and features consistent with ringed 18, 18p- and distal 18q syndrome. The multiple autoimmune findings in our patient lends further support to the idea of loci on chromosome 18 playing a role in autoimmune disease expression. Late onset RA and ILD in a patient with chromosome 18 abnormalities are novel findings and are additional conditions to be aware of in this population. PMID- 29568484 TI - How frequent are non-evidence-based health care beliefs in chiropractic students and do they vary across the pre-professional educational years. AB - Background: Evidence suggests that a students' beliefs already prior to entering a program may be important as a determinant in sustaining unsuitable health care beliefs. Our objectives were to investigate the proportion of Australian chiropractic students who hold non-evidence-based beliefs in the first year of study and the extent to which they may be involved in non-musculoskeletal health conditions. Finally, to see if this proportion varies over the course of the chiropractic program. Method: In 2016, students from two Australian chiropractic programs answered a questionnaire on how often they would give advice on five common health conditions in their future practices as well as their opinion on whether chiropractic spinal adjustments could prevent or help seven health related conditions. Results: From a possible 831 students, 444 responded (53%). Students were highly likely to offer advice (often/quite often) on a range of non musculoskeletal conditions. The proportions were lowest in first year and highest the final year. Also, high numbers of students held non-evidence-based beliefs about 'chiropractic spinal adjustments' which tended to occur in gradually decreasing in numbers in sequential years, except for fifth year when a reversal of the pattern occurred. Conclusions: New strategies are required for chiropractic educators if they are to produce graduates who understand and deliver evidence-based health care and able to be part of the mainstream health care system. PMID- 29560253 TI - Evaluation of Trichoderma spp., Pseudomonasfluorescens and Bacillus subtilis for biological control of Ralstonia wilt of tomato. AB - Background:Ralstonia spp. is a major pathogenic microbe for tomato, which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. Ralstonia spp. produces several virulence factors helping it to invade the plant's natural defense mechanism. Native isolates of Trichoderma spp., Pseudomonas fluorescens and Bacillus subtilis can be used as biocontrol agents to control the bacterial wilt and combined application of these beneficial microbes can give better results. Methods: Bacterial wilt infection in the field was identified by field experts and the infected plant part was used to isolate Ralstonia spp. in CPG media and was positively identified. Subsequently, the efficacy of the biocontrol agents was tested and documented using agar well diffusion technique and digital microscopy. 2ml of the microbial concentrate (10 9 cells/ml) was mixed in one liter of water and was applied in the plant root at the rate of 100 ml per plant as a treatment method. Results: It was observed that the isolated Trichoderma spp. AA2 and Pseudomonas fluorescens PFS were most potent in inhibiting the growth of Ralstonia spp. , showing ZOI 20.67 mm and 22.33 mm, respectively. Digital microscopy showed distinct inhibitory effect on the growth and survival of Ralstonia spp . The results from the field data indicated that Trichoderma spp. and Pseudomonas fluorescens alone were able to prevent 92% and 96% of the infection and combination of both were more effective, preventing 97% of infection. Chemical control methods prevented 94% of infection. Bacillus subtilis could only prevent 84 % of the infection. Conclusions: Antagonistic effect against Ralstonia spp. shown by native isolates of Trichoderma spp. and P. fluorescens manifested the promising potential as biocontrol agents. Combined application gave better results. Results shown by Bacillus subtilis were not significant. PMID- 29568482 TI - Presenting a New Standard Drug Model for Turmeric and Its Prized Extract, Curcumin. AB - Various parts of the turmeric plant have been used as medicinal treatment for various conditions from ulcers and arthritis to cardiovascular disease and neuroinflammation. The rhizome's curcumin extract is the most studied active constituent, which exhibits an expansive polypharmacology with influence on many key inflammatory markers. Despite the expansive reports of curcucmin's therapeutic value, clinical reliability and research repeatability with curcumin treatment are still poor. The pharmacology must be better understood and reliably mapped if curcumin is to be accepted and used in modern medical applications. Although the polypharmacology of this extract has been considered, in mainstream medicine, to be a drawback, a perspective change reveals a comprehensive and even synergistic shaping of the NF-kB pathway, including transactivation. Much of the inconsistent research data and unreliable clinical outcomes may be due to a lack of standardization which also pervades research standard samples. The possibility of other well-known curcumin by-products contributing in the polypharmacology is also discussed. A new flowchart of crosstalk in transduction pathways that lead to shaping of nuclear NF-kB transactivation is generated and a new calibration or standardization protocol for the extract is proposed which could lead to more consistent data extraction and improved reliability in therapy. PMID- 29560254 TI - Case Report: Dual nebulised antibiotics among adults with cystic fibrosis and chronic Pseudomonas infection. AB - Pulmonary exacerbations in adults with cystic fibrosis (CF) and chronic Pseudomonas aeruginosa (Psae) infection are usually treated with dual intravenous antibiotics for 14 days, despite the lack of evidence for best practice. Intravenous antibiotics are commonly associated with various systemic adverse effects, including renal failure and ototoxicity. Inhaled antibiotics are less likely to cause systematic adverse effects, yet can achieve airway concentrations well above conventional minimum inhibitory concentrations. Typically one inhaled antibiotic is used at a time, but dual inhaled antibiotics (i.e. concomitant use of two different inhaled antibiotics) may have synergistic effect and achieve better results in the treatment of exacerbations. We presented anecdotal evidence for the use of dual inhaled antibiotics as an acute treatment for exacerbations, in the form of a case report. A female in her early thirties with CF and chronic Psae infection improved her FEV 1 by 5% and 2% with two courses of dual inhaled antibiotics to treat exacerbations in 2016. In contrast, her FEV 1 changed by 2%, -2%, 0% and 2%, respectively, with four courses of dual intravenous antibiotics in 2016. Baseline FEV 1 was similar prior to all six courses of treatments. The greater FEV 1 improvements with dual inhaled antibiotics compared to dual intravenous antibiotics suggest the potential role of using dual inhaled antibiotics to treat exacerbations among adults with CF and chronic Psae infection, especially since a greater choice of inhaled anti-pseudomonal antibiotics is now available. A previous study in 1985 has looked at the concomitant administration of inhaled tobramycin and carbenicillin, by reconstituting antibiotics designed for parenteral administration. To our knowledge, this is the first literature to describe the concomitant use of two different antibiotics specifically developed for delivery via the inhaled route. PMID- 29568490 TI - Case Report: Non-infectious causes of palmoplantar rashes, what to consider. AB - Background: Palm and sole skin eruptions have a broad differential diagnosis. It is particularly important to recognize common causes as well as their association with certain chemotherapy regimens such as Capecitabine. Case report: A 79-year old woman presented with a painful rash on her hands and feet for 1 week. She had metastatic colon cancer and was in her third week of treatment with capecitabine. Her diagnosis was a medication side-effect from chemotherapy. Capecitabine was stopped and she had some clinical improvement over the next two days. She was discharged with oncology follow up for resumption of Capecitabine at a lower dose with improvement in her rash 3 weeks later.? Discussion: Skin rashes are a commonly encountered complaint in patients in the inpatient and outpatient setting. It is important to maintain a broad differential diagnosis in those with rashes of the palmoplantar surfaces of the hands and feet. Recognizing skin changes as a possible manifestation of underlying malignancy or a medication side effect is key in appropriate diagnosis and treatment. PMID- 29568488 TI - Recent advances in understanding acute respiratory distress syndrome. AB - Acute respiratory distress syndrome (ARDS) is characterized by acute diffuse lung injury, which results in increased pulmonary vascular permeability and loss of aerated lung tissue. This causes bilateral opacity consistent with pulmonary edema, hypoxemia, increased venous admixture, and decreased lung compliance such that patients with ARDS need supportive care in the intensive care unit to maintain oxygenation and prevent adverse outcomes. Recently, advances in understanding the underlying pathophysiology of ARDS led to new approaches in managing these patients. In this review, we want to focus on recent scientific evidence in the field of ARDS research and discuss promising new developments in the treatment of this disease. PMID- 29568489 TI - Ten steps to get started in Genome Assembly and Annotation. AB - As a part of the ELIXIR-EXCELERATE efforts in capacity building, we present here 10 steps to facilitate researchers getting started in genome assembly and genome annotation. The guidelines given are broadly applicable, intended to be stable over time, and cover all aspects from start to finish of a general assembly and annotation project. Intrinsic properties of genomes are discussed, as is the importance of using high quality DNA. Different sequencing technologies and generally applicable workflows for genome assembly are also detailed. We cover structural and functional annotation and encourage readers to also annotate transposable elements, something that is often omitted from annotation workflows. The importance of data management is stressed, and we give advice on where to submit data and how to make your results Findable, Accessible, Interoperable, and Reusable (FAIR). PMID- 29560255 TI - An explanatory model for the concept of mental health in Iranian youth. AB - Background: Mental health is considered as an integral and essential component of overall health. Its determinants and related factors are one of the most important research priorities, especially in adolescents and young people. Using a qualitative approach, the present study aimed to identify factors affecting the mental health of youth in Iran. Methods: In 2017, following content analysis principles, and using semi-structured in-depth interviews, we conducted a qualitative study exploring the opinions of young people about mental health. A targeted sampling method was used, and participants were young volunteers aged 18 to 30 who were selected from Tehran province, Iran. Inclusion criteria for participants was willingness to participate in the study, and ability to express their experiences. Data collection was done with individual in-depth interviews. According to the explanatory model, the interviews were directed toward the concept of mental health and path of causality and auxiliary behaviors. Results: 21 young adults participated, who met the study inclusion criteria, of whom 12 participants were male. Their mean age was 24.4 +/- 0.41 years and their education varied from primary school to Master's degree. Mental health was considered as mental well-being and a sense of satisfaction and efficacy, not only the presence of a disease or mental disorder. Based on the opinions of the interviewees, three factors of personal characteristics, family and society are involved in mental health. Individual factors were associated with behavioral and physical problems. One of the most important issues was revealed as tensions in societal and family conflicts. Economic problems and unemployment of young people were also extracted from the social factor. Conclusion: In Iran, social factors such as jobs for the unemployed and job security are considered as important determinants in the mental health of young people. PMID- 29568492 TI - Using regulatory genomics data to interpret the function of disease variants and prioritise genes from expression studies. AB - The identification of therapeutic targets is a critical step in the research and developement of new drugs, with several drug discovery programmes failing because of a weak linkage between target and disease. Genome-wide association studies and large-scale gene expression experiments are providing insights into the biology of several common and complex diseases, but the complexity of transcriptional regulation mechanisms often limit our understanding of how genetic variation can influence changes in gene expression. Several initiatives in the field of regulatory genomics are aiming to close this gap by systematically identifying and cataloguing regulatory elements such as promoters and enhacers across different tissues and cell types. In this Bioconductor workflow, we will explore how different types of regulatory genomic data can be used for the functional interpretation of disease-associated variants and for the prioritisation of gene lists from gene expression experiments. PMID- 29568493 TI - Validation of a yeast malate dehydrogenase 2 (Mdh2) antibody tested for use in western blots. AB - Malate dehydrogenases (Mdhs) reversibly convert malate to oxaloacetate and serve as important enzymes in several metabolic pathways. In the yeast Saccharomyces cerevisiae there are three Mdh isozymes, localized to different compartments in the cell. In order to identify specifically the Mdh2 isozyme, GenScript USA produced three different antibodies that we further tested by western blot. All three antibodies recognized the S. cerevisiae Mdh2 with different background and specificity properties. One of the antibodies had a relatively low background and high specificity and thus can be used for specific identification of Mdh2 in various experimental settings. PMID- 29568494 TI - Hubris and Sciences. AB - There has been an increasing awareness of the importance of leadership and decision making, including scientists and academics, over recent times. By whom and how decisions are made can have serious implications across all levels of society. Several people have been successful in their life and have been inflicted by excessive pride and self-confidence. There are times when the manifestations of such behaviours demonstrate noticeable signs of narcissism and on extreme cases, hubris. Hubris is an old concept originated from the Greek mythology. The risk of hubris affects politicians, leaders in business, scientists, academia, the military, entertainers, athletes and doctors (among many others). Power, especially absolute and unchecked power, is intoxicating and is manifested behaviourally in a variety of ways, ranging from amplified cognitive functions to lack of inhibition, poor judgment, extreme narcissism, deviant behaviour, and even cruelty. Hubristic behaviour of overconfidence, extreme pride together with an unwillingness to disregard advice makes powerful people in leadership positions to over-reach themselves with negative consequences for themselves and others. As the dangerous consequences of hubristic behaviours become more apparent and well described it is imperative that individuals, organisations and governments act to prevent such phenomena. Responsible leaders, including acclaimed scientists should exercise greater humility to the complexity and inherent uncertainty of their activities and strive to seek out and challenge hubristic behaviours. PMID- 29560256 TI - Reflections on the use of the World Health Organization's (WHO) OneHealth Tool: Implications for health planning in low and middle income countries (LMICs). AB - The World Health Organization (WHO) launched the OneHealth Tool (OHT) to help low and middle income countries to develop their capacities for sector-wide priority setting. In 2016, we sought to use the OHT to aid the Philippine Health Insurance Corporation (PHIC), the national health insurer of the Philippines, in decisions to expand benefit packages using cost-effectiveness analyses. With technical support from the WHO, we convened health planning officers from the Philippine Department of Health (DOH) and the Philippine Health Insurance Corporation (PHIC) conduct generalized cost-effective analyses (GCEA) of selected un-financed noncommunicable disease interventions using OHT. We collected epidemiological and cost data through health facility surveys, review of literature such as cost libraries and clinical practice guidelines, and expert consultations. Although we were unable to use GCEA results directly to set policy, we learnt important policy lessons which we outline here that might help inform other countries looking to inform service coverage decisions. Additionally, the entire process and GCEA visualizations helped high-level policymakers in the health sector, who have traditionally relied on ad hoc decision making, to realize the need for a systematic and transparent priority-setting process that can continuously provide the evidence needed to inform service coverage decisions.

AB - The Bacille Calmette Guerin (BCG) vaccine can provide decades of protection against tuberculosis (TB) disease, and although imperfect, BCG is proof that vaccine mediated protection against TB is a possibility. A new TB vaccine is, therefore, an inevitability; the question is how long will it take us to get there? We have made substantial progress in the development of vaccine platforms, in the identification of antigens and of immune correlates of risk of TB disease. We have also standardized animal models to enable head-to-head comparison and selection of candidate TB vaccines for further development. To extend our understanding of the safety and immunogenicity of TB vaccines we have performed experimental medicine studies to explore route of administration and have begun to develop controlled human infection models. Driven by a desire to reduce the length and cost of human efficacy trials we have applied novel approaches to later stage clinical development, exploring alternative clinical endpoints to prevention of disease outcomes. Here, global leaders in TB vaccine development discuss the progress made and the challenges that remain. What emerges is that, despite scientific progress, few vaccine candidates have entered clinical trials in the last 5 years and few vaccines in clinical trials have progressed to efficacy trials. Crucially, we have undervalued the knowledge gained from our "failed" trials and fostered a culture of risk aversion that has limited new funding for clinical TB vaccine development. The unintended consequence of this abundance of caution is lack of diversity of new TB vaccine candidates and stagnation of the clinical pipeline. We have a variety of new vaccine platform technologies, mycobacterial antigens and animal and human models. However, we will not encourage progression of vaccine candidates into clinical trials unless we evaluate and embrace risk in pursuit of vaccine development.

AB - The present work describes the assessment process, evaluation strategies, and cognitive intervention on a 9 years old child with selective mutism (SM), a monovular twin of a child also affected by mutism. Currently, the cognitive behavioral multimodal treatment seems the most effective therapeutic approach for children diagnosed with selective mutism (Capobianco & Cerniglia, 2018). The illustrated case confirms the role of biological factors involved in mutacic disorder but also highlights the importance of environmental influences in the maintenance of the disorder with respect to relational and contextual dynamics (e.g. complicity between sisters, family relationships). The article discusses furthermore the importance of an early diagnosis as a predictor of positive treatment outcomes. PMID- 29568496 TI - Missing the egocentric spatial reference: a blank on the map. AB - Egocentric (self-centered) and allocentric (viewpoint independent) representations of space are essential for spatial navigation and wayfinding. Deficits in spatial memory come with age-related cognitive decline, are marked in mild cognitive impairment (MCI) and Alzheimer's disease (AD), and are associated with cognitive deficits in autism. In most of these disorders, a change in the brain areas engaged in the spatial reference system processing has been documented. However, the spatial memory deficits observed during physiological and pathological aging are quite different. While patients with AD and MCI have a general spatial navigation impairment in both allocentric and egocentric strategies, healthy older adults are particularly limited in the allocentric navigation, but they can still count on egocentric navigation strategy to solve spatial tasks. Therefore, specific navigational tests should be considered for differential diagnosis between healthy and pathological aging conditions. Finally, more research is still needed to better understand the spatial abilities of autistic individuals. PMID- 29568499 TI - NFAT control of immune function: New Frontiers for an Abiding Trooper. AB - Nuclear factor of activated T cells (NFAT) was first described almost three decades ago as a Ca 2+/calcineurin-regulated transcription factor in T cells. Since then, a large body of research uncovered the regulation and physiological function of different NFAT homologues in the immune system and many other tissues. In this review, we will discuss novel roles of NFAT in T cells, focusing mainly on its function in humoral immune responses, immunological tolerance, and the regulation of immune metabolism. PMID- 29568500 TI - Radial glial cells in the adult dentate gyrus: what are they and where do they come from? AB - Adult neurogenesis occurs in the dentate gyrus in the mammalian hippocampus. These new neurons arise from neural precursor cells named radial glia-like cells, which are situated in the subgranular zone of the dentate gyrus. Here, we review the emerging topic of precursor heterogeneity in the adult subgranular zone. We also discuss how this heterogeneity may be established during development and focus on the embryonic origin of the dentate gyrus and radial glia-like stem cells. Finally, we discuss recently developed single-cell techniques, which we believe will be critical to comprehensively investigate adult neural stem cell origin and heterogeneity. PMID- 29568501 TI - Advances in understanding the molecular basis of skin fragility. AB - Skin fragility refers to a large group of conditions in which the ability of the skin to provide protection against trivial mechanical trauma is diminished, resulting in the formation of blisters, erosions, wounds, or scars. Acquired and physiological skin fragility is common; genetic disorders are rare but give insight into the molecular mechanisms ensuring skin stability. The paradigm is represented by inherited epidermolysis bullosa. This review is focused on recent advances in understanding the molecular basis of genetic skin fragility, including emerging concepts, controversies, unanswered questions, and opinions of the author. In spite of the advanced knowledge on the genetic causes of skin fragility, the molecular pathology is still expanding. Open questions in understanding the molecular basis of genetic skin fragility are the following: what are the causes of phenotypes which remain genetically unsolved, and what are the molecular modifiers which might explain phenotypic differences among individuals with similar mutations? New mutational mechanisms and new genes have recently been discovered and are briefly described here. Comprehensive next generation sequencing-based genetic testing improved mutation detection and facilitated the identification of the genetic basis of unclear and new phenotypes. Characterization of the biochemical and cell biological consequences of the genetic variants is challenging and laborious but may represent the basis for personalized therapeutic approaches. Molecular modifiers of skin fragility have been uncovered in particular animal and genetic models but not in larger cohorts of patients. This scientific progress is the basis for revisions of the epidermolysis bullosa classification and for innovative therapeutic approaches designed for this intractable condition. PMID- 29568502 TI - Associations between atopic dermatitis and other disorders. AB - Atopic dermatitis is a heterogeneous, chronic, and inflammatory skin disease that is associated with a profound symptom burden. Recent studies have demonstrated associations between atopic dermatitis and a number of multi-organ and systemic disorders. The origin of these comorbid conditions is likely multifactorial, with combined effects of skin-barrier disruption, immune dysregulation, intense symptoms, and iatrogenic complications. Some of these comorbid conditions appear to be related to the underlying severity of atopic dermatitis and inadequate disease control. This review will summarize recent developments in the understanding of the comorbid health disorders associated with atopic dermatitis, particularly infections, sleep disturbances, and cardiovascular disease. PMID- 29568503 TI - Recent advances in the management of large and complex colonic polyps. AB - The endoscopic management of large colonic polyps is a rapidly changing field. Rapid evolution in endoscopic techniques and skills has resulted in diminishing the role of surgery in the management of larger and complex polyps. This is resulting in organ preservation for many who otherwise would have undergone surgery. However, it also poses new challenges. This article reviews these new advances and the developments which are overcoming these difficulties. PMID- 29568504 TI - Renal cell carcinoma: a review of biology and pathophysiology. AB - Over the past decade, our understanding of the biology and pathophysiology of renal cell carcinoma (RCC) has improved significantly. Insight into the disease process has helped us in developing newer therapeutic approaches toward RCC. In this article, we review the various genetic and immune-related mechanisms involved in the pathogenesis and development of this cancer and how that knowledge is being used to develop therapeutic targeted drugs for the treatment of RCC. The main emphasis of this review article is on the most common genetic alterations found in clear cell RCC and how various drugs are currently targeting such pathways. This article also looks at the role of the immune system in allowing the growth of RCC and how the immune system can be manipulated to reactivate cytotoxic immunity against RCC. PMID- 29568506 TI - Recent advances in antiviral interferon-stimulated gene biology. AB - The interferon response protects cells from invading viral pathogens by transcriptionally inducing the expression of interferon-stimulated genes (ISGs), some of which encode effectors with varied antiviral functions. As screening technologies improve and mouse model development quickens, more ISGs are continually being identified, characterized mechanistically, and evaluated for protective roles in vivo. This review highlights selected recent findings of ISG effectors that contribute to our understanding of the interferon antiviral response. PMID- 29568505 TI - Cutting down the time to identify challenging tumor therapeutic targets and drug combinations using synthetic lethal approaches. AB - Cancer drug discoverers and developers are blessed and cursed with a plethora of drug targets in the tumor cells themselves and the surrounding stromal elements. This bounty of targets has, at least in part, inspired the rapid increase in the number of clinically available small-molecule, biological, and cellular therapies for solid and hematological malignancies. Among the most challenging questions in cancer therapeutics, especially for small molecules, is how to approach loss-of function gene mutations or deletions that encode tumor suppressors. A second mounting question is what are the optimal drug combinations. This article will briefly review the recent advances in exploiting in vitro and in vivo synthetic lethal screens to expose cancer pharmacological targets with the goal of developing new drug combinations. PMID- 29568507 TI - Separation of Saturated Fatty Acids and Fatty Acid Methyl Esters with Epoxy Nanofiltration Membranes. AB - Epoxy nanofiltration membranes were fabricated by the step polymerization of a primary diamine and a diepoxide or triepoxide conomomer. Membrane selectivity and flux were tuned by changing the identity of the diepoxides and by increasing the concentration of triepoxides in the polymerization. The membranes were used to separate even chain length saturated fatty acids (FAs) and saturated fatty acid methyl esters (FAMEs) that possessed molecular weights between 80 - 300 g mol-1. Our membranes show excellent selectivities of up to 100:1 for the separation of the C4-C18 FAMEs. The flux of the FAMEs through the membranes showed an exponential dependence based on the number of carbons. Fabrication of thin epoxy membranes with thicknesses of 150 nm allowed for an increase in flux of FAMEs through the membrane and demonstrated that these separations can be used under industrially relevant conditions. PMID- 29568508 TI - Targeting protein-loaded CB[8]-mediated supramolecular nanocarriers to cells. AB - Supramolecular amphiphiles, consisting of ternary complexes of cucurbit[8]uril (CB[8]), an alkylated paraquat derivative and a tetraethylene glycol functionalized azobenzene, self-assemble into vesicles of about 200 nm in diameter. The outer surface of the vesicles was functionalized with cell targeting ligands. These vesicles were employed for loading and delivery of proteins into cells. Supramolecular amphiphile-derived vesicles show great promise as nanocarriers of functional molecules to be transferred into cells. PMID- 29568509 TI - 17O solid-state NMR spectroscopy of A2B2O7 oxides: quantitative isotopic enrichment and spectral acquisition? AB - The potential of 17O NMR spectroscopy for the investigation of A2B2O7 ceramic oxides important in the encapsulation of radioactive waste is demonstrated, with post-synthetic enrichment by exchange with 17O2 gas. For Y2Sn2O7, Y2Ti2O7 and La2Sn2O7 pyrochlores, enrichment of the two distinct O species is clearly non quantitative at lower temperatures (~700 degrees C and below) and at shorter times, despite these being used in prior work, with preferential enrichment of OA2B2 favoured over that of OA4. At higher temperatures, the 17O NMR spectra suggest that quantitative enrichment has been achieved, but the integrated signal intensities do not reflect the crystallographic 1 : 6 (O1 : O2) ratio until corrected for differences in T1 relaxation rates and, more importantly, the contribution of the satellite transitions. 17O NMR spectra of Y2Zr2O7 and Y2Hf2O7 defect fluorites showed little difference with any variation in enrichment temperature or time, although an increase in the absolute level of enrichment (up to ~7.5%) was observed at higher temperature. DFT calculations show that the six distinct resonances observed cannot be assigned unambiguously, as each has contributions from more than one of the five possible next nearest neighbour environments. For La2Ti2O7, which adopts a layered perovskite-like structure, little difference in the spectral intensities is observed with enrichment time or temperature, although the highest absolute levels of enrichment (~13%) were obtained at higher temperature. This work demonstrates that 17O NMR has the potential to be a powerful probe of local structure and disorder in oxides, but that considerable care must be taken both in choosing the conditions for 17O enrichment and the experimental acquisition parameters if the necessary quantitative measurements are to be obtained for more complex systems. PMID- 29568510 TI - Flexible corner cube retroreflector array for temperature and strain sensing. AB - Optical sensors for detecting temperature and strain play a crucial role in the analysis of environmental conditions and real-time remote sensing. However, the development of a single optical device that can sense temperature and strain simultaneously remains a challenge. Here, a flexible corner cube retroreflector (CCR) array based on passive dual optical sensing (temperature and strain) is demonstrated. A mechanical embossing process was utilised to replicate a three dimensional (3D) CCR array in a soft flexible polymer film. The fabricated flexible CCR array samples were experimentally characterised through reflection measurements followed by computational modelling. As fabricated samples were illuminated with a monochromatic laser beam (635, 532, and 450 nm), a triangular shape reflection was obtained at the far-field. The fabricated flexible CCR array samples tuned retroreflected light based on external stimuli (temperature and strain as an applied force). For strain and temperature sensing, an applied force and temperature, in the form of weight suspension, and heat flow was applied to alter the replicated CCR surface structure, which in turn changed its optical response. Directional reflection from the heated flexible CCR array surface was also measured with tilt angle variation (max. up to 10 degrees ). Soft polymer CCRs may have potential in remote sensing applications, including measuring the temperature in space and in nuclear power stations. PMID- 29568511 TI - A novel method for the collection of nanoscopic vesicles from an organotypic culture model. AB - Nanovesicles, exosomes and other membrane bound particles excreted by cells are currently gaining research attention since they have been shown to play a significant role in many biologically related processes. Vesicles are now thought to mediate cellular communication, transmission of some diseases and pathologically mediated calcification. Matrix vesicles have long been proposed to be central to the controlled mineralisation of bone. They remain relatively poorly studied, however, since they are challenging to extract from biological media. One difficulty is the presence of a mineral content in comparison to pure lipid vesicles, meaning that standard separation process such as ultracentrifugation are unable to precisely separate on the basis of size or weight. In this paper we report the separation of matrix vesicles from an organotypic bone culture system using a process of immunoprecipitation. Matrix vesicles were extracted using polymeric beads that were modified with an antibody for tissue non-specific alkaline phosphatase (TNALP), a surface marker abundant in bone-derived vesicles. The vesicles isolated were positive for adenosine triphosphate (ATP), the substrate for TNALP and were demonstrated to have a high binding affinity to type I collagen, the principal collagen type found in bone. This protocol enables more detailed study of the process and regulation of mineralisation. PMID- 29568512 TI - Electronic structure, polaron formation, and functional properties in transition metal tungstates. AB - Transition-metal tungstates MWO4 (M = Co, Ni, Cu, Zn) have applications in many areas, including supercapacitors. A good understanding of the electronic structure is essential to understanding their functional properties. Here, we report a first-principles study of the materials using hybrid density-functional calculations. The electronic structure is analyzed with a focus on the nature of the electronic states near the band edges. We find that hole polarons can form at the Co lattice site in CoWO4 and the O site in NiWO4, CuWO4, and ZnWO4, resulting in the formation of Co3+ in the former and O- in the latter. The electrochemical activity observed in certain tungstate compounds, but not in others, appears to be related to the ability to form hole polarons on the transition-metal ions. The formation energy and migration barrier of the hole polaron in CoWO4 are also calculated and the results are employed to understand the reported p-type conductivity. PMID- 29568513 TI - Assaying sensory ciliopathies using calcium biosensor expression in zebrafish ciliated olfactory neurons. AB - Background: Primary cilia mediate signal transduction by acting as an organizing scaffold for receptors, signalling proteins and ion channels. Ciliated olfactory sensory neurons (OSNs) organize olfactory receptors and ion channels on cilia and generate a calcium influx as a primary signal in odourant detection. In the zebrafish olfactory placode, ciliated OSNs and microvillus OSNs constitute the major OSN cell types with distinct odourant sensitivity. Methods: Using transgenic expression of the calcium biosensor GCaMP5 in OSNs, we analysed sensory cilia-dependent odour responses in live zebrafish, at individual cell resolution. oval/ift88 mutant and ift172 knockdown zebrafish were compared with wild-type siblings to establish ciliated OSN sensitivity to different classes of odourants. Results: oval/ift88 mutant and ift172 knockdown zebrafish showed fewer and severely shortened OSN cilia without a reduction in OSN number. The fraction of responding OSNs and response amplitudes to bile acids and food odour, both sensed by ciliated OSNs, were significantly reduced in ift88 mutants and ift172 deficient embryos, while the amino acids responses were not significantly changed. Conclusions: Our approach presents a quantitative model for studying sensory cilia signalling using zebrafish OSNs. Our results also implicate ift172 deficiency as a novel cause of hyposmia, a reduced sense of smell, highlighting the value of directly assaying sensory cilia signalling in vivo and supporting the idea that hyposmia can be used as a diagnostic indicator of ciliopathies. PMID- 29568514 TI - Prevalence and antibiotic resistance of bacteria isolated from the cerebrospinal fluid of neurosurgical patients at Peking Union Medical College Hospital. AB - Background: Postoperative central nervous system infections (PCNSIs) represent a serious complication, and the timely use of antibiotics guided by the identification of the causative pathogens and their antibiotic sensitivities is essential for treatment. However, there are little data regarding the prevalence of PCNSI pathogens in China. The aim of this study is to investigate the features of pathogens in patients with PCNSIs, which could help clinicians to choose the appropriate empirical antibiotic therapy. Methods: We retrospectively examined the positive CSF cultures in patients who underwent craniotomy between January 2010 and December 2015. We collected data, including demographic characteristics, type of neurosurgery, laboratory data, causative organisms and antimicrobial susceptibility testing results. Results: A total of 62 patients with 90 isolates out of 818 patients with 2433 CSF culture samples were available for data analysis. The estimated incidence and culture-positive rate of PCNSIs were approximately 0.9 and 7.5%, respectively. The predominant organism was coagulase negative staphylococci, of which most were methicillin-resistant coagulase negative staphylococci (MRCoNS). All were susceptible to vancomycin, linezolid, rifampicin and amoxicillin-clavulanate. Acinetobacter baumannii was the most frequent causative Gram-negative agent and was resistant to 12 out of 18 antimicrobials tested. The sensitivity rates for tigecycline and minocycline were only 40 and 33%, respectively. Conclusion: PCNSIs could lead to high mortality. Although the MRCoNS were the predominant organism, the management of Acinetobacter baumannii was a major clinical challenge with few effective antimicrobials in PCNSIs. PMID- 29568515 TI - Prevalence and molecular characterization of Staphylococcus aureus from human stool samples. AB - Background: To determine the prevalence of intestinal S. aureus colonization of patients at a large teaching hospital and determine the molecular characteristics of the identified strains. The second objective of this research was to determine risk factors associated with S. aureus intestinal colonization. Methods: A cross sectional study of 781 specimens from inpatients and outpatients at the University of Iowa Hospitals and Clinics Clinical Microbiology Laboratory was conducted. S. aureus was identified using traditional culture methodologies. Methicillin-resistance was determined via PCR of the mecA gene. PVL PCR, spa typing, and antimicrobial sensitivity testing were also done. A nested case control study was done on a subset of patients with all colonized patients defined as cases and non-colonized controls. Medical record abstractions were done to identify risk factors for intestinal colonization in the nested study. Results: Out of 625 patients included in the final study, 58 were positive for S. aureus (9.3%). One isolate was positive for the PVL gene. A high number of isolates were resistant to multiple antibiotics including oxacillin (43.1%), erythromycin (51.7%), and levofloxacin (41.4%). All isolates were susceptible to vancomycin, daptomycin, linezolid, and quinupristin-dalfopristin. In the nested study, having a disease or condition of the gastrointestinal tract significantly increased the odds of intestinal colonization (OR: 1.96, 95% CI: 1.04-3.7; aOR: 13.9, 95% CI: 1.67-115.7). No other variables were significantly associated with increased odds of colonization. Conclusions: S. aureus was identified from the stool of patients at the University of Iowa Hospitals and Clinics, with a large number of those isolates being resistant to antibiotics and may serve a reservoir for subsequent infections as well as asymptomatic transmission. PMID- 29568516 TI - Development of a patient-centred intervention to improve knowledge and understanding of antibiotic therapy in secondary care. AB - Background: We developed a personalised antimicrobial information module co designed with patients. This study aimed to evaluate the potential impact of this patient-centred intervention on short-term knowledge and understanding of antimicrobial therapy in secondary care. Methods: Thirty previous patients who had received antibiotics in hospital within 12 months were recruited to co-design an intervention to promote patient engagement with infection management. Two workshops, containing five focus-groups were held. These were audio-recorded. Data were analysed using a thematic framework developed deductively based on previous work. Line-by-line coding was performed with new themes added to the framework by two researchers. This was used to inform the development of a patient information module, embedded within an electronic decision support tool (CDSS).The intervention was piloted over a four-week period at Imperial College Healthcare NHS Trust on 30 in-patients. Pre- and post-intervention questionnaires were developed and implemented to assess short term changes in patient knowledge and understanding and provide feedback on the intervention. Data were analysed using SPSS and NVIVO software. Results: Within the workshops, there was consistency in identified themes. The participants agreed upon and co-designed a personalised PDF document that could be integrated into an electronic CDSS to be used by healthcare professionals at the point-of-care. Their aim for the tool was to provide individualised practical information, signpost to reputable information sources, and enhance communication between patients and healthcare professionals.Eighteen out of thirty in-patients consented to participant in the pilot evaluation with 15/18(83%) completing the study. Median (range) age was 66(22-85) years. The majority were male (10/15;66%). Pre-intervention, patients reported desiring further information regarding their infections and antibiotic therapy, including side effects of treatment. Deployment of the intervention improved short term knowledge and understanding of individuals infections and antibiotic management with median (IQR) scores improving from 3(2-5)/13 to 10(6 11)/13. 13/15(87%) reported that they would use the intervention again. Conclusion: A personalised, patient-centred intervention improved understanding and short-term knowledge of infections and antibiotic therapy in participating patients'. Long term impact on attitudes and behaviours post discharge will be further investigated. PMID- 29568517 TI - Surfen and oxalyl surfen decrease tau hyperphosphorylation and mitigate neuron deficits in vivo in a zebrafish model of tauopathy. AB - Background: Tauopathies comprise a family of neurodegenerative disorders including Alzheimer's disease for which there is an urgent and unmet need for disease-modifying treatments. Tauopathies are characterized by pathological tau hyperphosphorylation, which has been shown to correlate tightly with disease progression and memory loss in patients suffering from Alzheimer's disease. We recently demonstrated an essential requirement for 3-O-sulfated heparan sulfate in pathological tau hyperphosphorylation in zebrafish, a prominent model organism for human drug discovery. Here, we investigated whether in vivo treatment with surfen or its derivatives oxalyl surfen and hemisurfen, small molecules with heparan sulfate antagonist properties, could mitigate tau hyperphosphorylation and neuronal deficits in a zebrafish model of tauopathies. Results: In vivo treatment of Tg[HuC::hTauP301L; DsRed] embryos for 2 days with surfen or oxalyl surfen significantly reduced the accumulation of the pThr181 tau phospho-epitope measured by ELISA by 30% and 51%, respectively. Western blot analysis also showed a significant decrease of pThr181 and pSer396/pSer404 in embryos treated with surfen or oxalyl surfen. Immunohistochemical analysis further confirmed that treatment with surfen or oxalyl surfen significantly decreased the AT8 tau epitope in spinal motoneurons. In addition, in vivo treatment of Tg[HuC::hTauP301L; DsRed] embryos with surfen or oxalyl surfen significantly rescued spinal motoneuron axon-branching defects and, as a likely consequence, the impaired stereotypical touch-evoked escape response. Importantly, treatment with hemisurfen, a surfen derivative devoid of heparan sulfate antagonist activity, does not affect tau hyperphosphorylation, nor neuronal or behavioural deficits in Tg[HuC::hTauP301L; DsRed] embryos. Conclusion: Our findings demonstrate for the first time that surfen, a well-tolerated molecule in clinical settings, and its derivative, oxalyl surfen, could mitigate or delay neuronal defects in tauopathies, including Alzheimer's disease. PMID- 29568518 TI - Exercise-induced increase in brain-derived neurotrophic factor in human Parkinson's disease: a systematic review and meta-analysis. AB - Background: Animal models of exercise and Parkinson's disease (PD) have found that the physiologic use of exercise may interact with the neurodegenerative disease process, likely mediated by brain derived neurotrophic factor (BDNF). No reviews so far have assessed the methodologic quality of available intervention studies or have bundled the effect sizes of individual studies on exercise induced effects on BDNF blood levels in human PD. Research design and methods: We searched MEDLINE, EMBASE, Cochrane Library, PsycINFO and PubMed from inception to June 2017. Results: Data aggregated from two randomized controlled trials and four pre-experimental studies with a total of 100 ambulatory patients with idiopathic PD (Hoehn/Yahr <=3) found improvements in BDNF blood concentration levels in all 6 studies (two RCTs and 4 pre-experimental studies). Pooled BDNF level change scores from the 2 RCTs resulted in a significant homogeneous summary effect size (Standardized Mean Difference 2.06, 95% CI 1.36 to 2.76), and a significant heterogeneous SES for the motor part of the UPDRS-III examination (MD -5.53, 95% CI -10.42 to -0.64). Clinical improvements were noted in all studies using a variety of outcome measures. Limitations: The evidence-base consists primarily of small studies with low to moderate methodological quality. Conclusions: This review provides preliminary evidence for the effectiveness of physical exercise treatments for persons with PD on BDNF blood levels. Further research is needed. PMID- 29568519 TI - Late open conversion after endovascular repair of abdominal aneurysm failure: Better and easier option than complex endovascular treatment. AB - Aim: Conversion to open repair becomes the last option in case of endovascular repair of abdominal aneurysm failure, when radiological interventional procedures are unfeasible. While early conversion to open repair generally derives from technical errors, aetiopathogenesis and results of late conversion to open repair often remain unclear. Methods: We report data from our Institute's experience on late conversion to open repair. Twenty-two late conversion to open repairs out of 435 consecutive patients treated during a 18 years period, plus two endovascular repair of abdominal aneurysms performed in other centres, are analysed. The indication for conversion to open repair was aneurysm enlargement because of type I, type III, type II endoleak and endotension. Even if seven cases (23%) had shown an initial aneurysmal shrinkage, in a later phase, the sac began to enlarge again. In 12 patients, conversion to open repair was the last chance after unsuccessful secondary endovascular procedures. Results: Three cases (12.5%) were treated in emergency. Aortic cross-clamping was only infrarenal in 10 cases, only or temporarily suprarenal in 14 and temporarily supraceliac in 9 cases, for 19 total and 5 partial endograft excisions. Two patients died for Multiple Organ Failure (MOF), on 42nd (endovascular repair of abdominal aneurysm infection) and 66th postoperative day. No other conversion to open repair-related deaths or major complications were revealed by follow-up post-conversion to open repair (mean: 68 months ranging from 24 to 180 months). Conclusion: Late conversion to open repair is often an unpredictable event. It represents a technical challenge: specifically, the most critical point is the proximal aortic clamping that often temporarily excludes the renal circulation. In our series, conversion to open repair can be performed with a low rate of complications. In response to an endovascular repair of abdominal aneurysm failure, before applying complex procedures of endovascular treatment, conversion to open repair should be taken into account. PMID- 29568520 TI - Effects of chronic dexamethasone administration on hyperglycemia and insulin release in goats. AB - Background: Dexamethasone (Dex), a synthetic glucocorticoid, is among the most commonly used drugs worldwide in animals and humans as an anti-inflammatory and immunosuppressive agent. GC has profound effects on plasma glucose level and other metabolic conditions. However, the effect of prolonged use of Dex on glucose metabolism in ruminants is still unclear. Results: Ten goats were randomly assigned to two groups: the control goats were injected with saline, and the Dex-treated goats were intramuscularly injected daily for 21 d with 0.2 mg/kg Dex. The results showed that plasma glucose and insulin concentrations were significantly increased after Dex administration (P < 0.05). Additionally, the content of hepatic glycogen was also markedly increased in Dex-treated goats (P < 0.01), while the content of glycogen in dorsal longissimus was unchanged by Dex (P > 0.05). The expression of several key genes, involved in blood glucose regulation, was detected by real-time PCR in the small intestine, skeletal muscle and liver. The expression of glucose transporter type 2 (GLUT2), sodium-glucose transporter 1 (SGLT1) and sodium-potassium ATPase (Na-K/ATPase) in the small intestine were generally increased by Dex, and GLUT2 mRNA expression was significantly up-regulated (P < 0.05). In liver, the expression of genes involved in gluconeogenesis including glucose-6-phosphatase catalytic subunit (G6PC), cytosolic form of phosphoenolpyruvate carboxykinase (PCK1) and pyruvate carboxylase (PC), were significantly down-regulated by Dex. However, the protein expression levels of PCK1 & PCK2 were significantly increased by Dex, suggesting a post-transcriptional regulation. In dorsal longissimus, the mRNA expression of genes associated with gluconeogenesis and the insulin signaling pathway were generally up-regulated by Dex, but the mRNA expression of two markers of muscle atrophy, namely F-box protein 32 (FBXO32/Atrogin1) and muscle RING-finger protein 1 (MuRF1), was not altered by Dex. Conclusions: Taken together, these results indicate that chronic administration of a low dosage of Dex induces hyperglycemia mainly through gluconeogenesis activation in the goat liver. PMID- 29568521 TI - Elevated circulatory levels of leptin and resistin impair therapeutic efficacy of dacarbazine in melanoma under obese state. AB - Background: Obesity is associated with increased risk, poor prognosis and outcome of therapy, in various cancers. Obesity-associated factors or adipokines, especially leptin and resistin, are purported to promote growth, survival, proliferation, and invasiveness of cancer cells. However, the mechanistic link between these adipokines and therapeutic response in malignancies is not clearly understood. Methods: ob/ob and db/db mouse models were used in this study to evaluate the role of leptin and resistin towards the outcome of dacarbazine (DTIC) therapy in melanoma. Unique in vitro approaches were employed to complement in vivo findings by culturing melanoma cells in the serum collected from the experimental mice. Results: Here, we have shown the role of important adipokines leptin and resistin in growth and the outcome of DTIC therapy in melanoma. Both leptin and resistin not only enhance proliferation of melanoma cells but also are involved in impairing the therapeutic efficacy of DTIC. Leptin and resistin treatment caused an increase in the protein levels of fatty acid synthase (FASN) and caveolin 1 (Cav-1) respectively, through their stabilization in A375 cells. Further, it was observed that leptin and resistin impaired the response of melanoma cells to DTIC via upregulation of heat shock protein 90 (Hsp90) and P-glycoprotein (P-gp) respectively. Conclusion: These findings unraveled the involvement of adipokines (leptin and resistin) in melanoma progression, and more importantly, in the outcome of DTIC therapy. PMID- 29568522 TI - Association of sleep quality with excessive daytime somnolence and quality of life of elderlies of community. AB - Background: The progressive increase in the elderly population contributes to the fact that studies on human aging have important attention of health professionals and government agents, since they present a great challenge regarding public health. Our objective is to characterize the profile of older people with poor sleep quality and analyze possible associations with excessive daytime somnolence, quality of life and functional mobility. Methods: This is a cross sectional descriptive study, involving elderlies of the community, with the questionnaires Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, WHOQOL-OLD and application of the Timed Up and Go test - TUG. Descriptive statistics, Student's t test for paired samples and Pearson's correlation coefficient (p <= 0.05) were used. Results: We recruited 131 elderly people, predominantly female (87%); mean age 68 +/- 7 years, low per capita income (84.8% <= 2 minimum wage), low education (86.3% <= 3 years of study), and mostly staying with relatives (67.9%), married (39.7%) or amassed (35.9%). Seventy-one percent of the sample is above normal weight, 90.1% of women have an abdominal circumference >= 80 cm and a high prevalence of chronic and psychosocial diseases was identified in the self-report, and the risk of obstructive sleep apnea in 38.2%. The mean PSQI, Epworth Sleepiness Scale, WHOQOL-OLD and TUG were equal to, respectively, 11.2 +/- 3.2; 8.32 +/- 2.2; 84.8 +/- 10.2 and 8.97 +/- 2. An association of sleep quality with excessive daytime somnolence and quality of life, while not with functional mobility, was observed. Conclusion: The results of the present study allowed to identify a sleep quality associated with excessive daytime somnolence and quality of life and also to characterize the profile of elders with poor sleep quality. PMID- 29568523 TI - Blood microvasculature and lymphatic densities in endometrial polyps and adjacent and distant endometrium. AB - Objective: Endometrial polyps are localised growths of endometrial tissue containing glands, stroma and blood vessels, covered with epithelium. The reported prevalence of endometrial polyps is dependent upon the population being studied and the uterine imaging technique utilised. The light microscopy literature provides very little information regarding their microvasculature and lymphatic systems; however, a plethora of ultrasound data demonstrating single central arteries in most medium- or large-sized endometrial polyps are well documented. Methods: Archived formalin-fixed paraffin-embedded blocks of endometrial curettings were retrieved from files for women with confirmed endometrial polyps (n = 20) and women with normal endometrium (control endometrium; n = 32). Immunohistochemistry was performed with the antibodies CD31 (blood vessels) and D2-40 (lymphatics). Blood vessels and lymphatics were quantified in endometrial polyps and adjacent, distant and control endometrium. Results: CD31 and D2-40 staining was present in all specimens, although there were no significant differences in blood vessel (F(3,70) = 2.36, p = 0.079) and lymphatic (F(3,70) = 0.16, p = 0.920) densities between endometrial polyps as well as adjacent, distant and control endometrium. There were also no significant differences in women with endometrial polyp-associated bleeding and those with no bleeding. In relation to infertility, there were no significant differences found in blood and lymphatic densities between women with endometrial polyps who were infertile and those with endometrial polyps who were fertile. Conclusion: Small blood vessel wall and perivascular structures rather than the distribution of vessels may be associated with abnormal bleeding. PMID- 29568525 TI - Two patients with rare mixed adenoneuroendocrine carcinomas of the rectum. AB - Mixed adenoneuroendocrine carcinomas of the gastrointestinal tract are until today poorly understood and thus very challenging for interdisciplinary therapy. We herewith report the first case series of patients with a primary mixed adenoneuroendocrine carcinoma of the rectum. Both cases were initially diagnosed as adenocarcinoma and only secondarily with mixed adenoneuroendocrine carcinoma and had a poor outcome due to a rapid tumor progression and resistance to chemotherapy. A 65-year-old female presented with local tumor recurrence and hepatopulmonary metastasis 1 year after primary surgery for adenocarcinoma of the rectum and consecutive radiochemotherapy regimen. Fluorouracil (5-FU) was followed by bevacizumab- and capecitabine-based chemotherapy but had to be discontinued due to side effects and progressive disease. Progressive local pain syndrome accompanied by recurrent bleeding episodes led to a local tumor debulking operation. Afterward, mixed adenoneuroendocrine carcinoma as the underlying diagnosis in the final histopathological examination was detected. The patient died 3 months after the operation in the context of a fulminant tumor progress. A 63-year-old male patient underwent neoadjuvant radiochemotherapy and laparoscopic rectum resection. After 5 months, postoperative oxaliplatin/capecitabine-based adjuvant chemotherapy was switched to carboplatin/etopsid due to a progressive polyneuropathy and biopsy-proven pulmonary metastasis. The patient then had to be switched to local radiation of cerebral metastases and Topotecan due to cerebral bleeding episodes but died 18 months after the initial diagnosis. In conclusion of our case series, mixed adenoneuroendocrine carcinomas of the rectum should be considered as a rare but aggressive tumor entity. An early and detailed histopathological diagnosis is required in order to establish an individual interdisciplinary treatment concept. PMID- 29568524 TI - Novel therapeutic strategies for degenerative disc disease: Review of cell biology and intervertebral disc cell therapy. AB - Intervertebral disc degeneration is a disease of the discs connecting adjoining vertebrae in which structural damage leads to loss of disc integrity. Degeneration of the disc can be a normal process of ageing, but can also be precipitated by other factors. Literature has made substantial progress in understanding the biological basis of intervertebral disc, which is reviewed here. Current medical and surgical management strategies have shortcomings that do not lend promise to be effective solutions in the coming years. With advances in understanding the cell biology and characteristics of the intervertebral disc at the molecular and cellular level that have been made, alternative strategies for addressing disc pathology can be discovered. A brief overview of the anatomic, cellular, and molecular structure of the intervertebral disc is provided as well as cellular and molecular pathophysiology surrounding intervertebral disc degeneration. Potential therapeutic strategies involving stem cell, protein, and genetic therapy for intervertebral disc degeneration are further discussed. PMID- 29568526 TI - Erythrocyte fatty acid profiles in children are not predictive of autism spectrum disorder status: a case control study. AB - Biomarkers promise biomolecular explanations as well as reliable diagnostics, stratification, and treatment strategies that have the potential to help mitigate the effects of disorders. While no reliable biomarker has yet been found for autism spectrum disorder (ASD), fatty acids have been investigated as potential biomarkers because of their association with brain development and neural functions. However, the ability of fatty acids to classify individuals with ASD from age/gender-matched neurotypical (NEU) peers has largely been ignored in favor of investigating population-level differences. Contrary to existing work, this classification task between ASD and NEU cohorts is the main focus of this work. The data presented herein suggest that fatty acids do not allow for classification at the individual level. PMID- 29568527 TI - Leukadherin-1 ameliorates endothelial barrier damage mediated by neutrophils from critically ill patients. AB - Background: Multi-organ failure occurs during critical illness and is mediated in part by destructive neutrophil-to-endothelial interactions. The beta2 integrin receptor, CR3 (complement receptor 3; Mac-1; CD11b/CD18), which binds endothelial intercellular adhesion molecule-1 (ICAM-1), plays a key role in promoting the adhesion of activated neutrophils to inflamed endothelia which, when prolonged and excessive, can cause vascular damage. Leukadherin-1 (LA-1) is a small molecule allosteric activator of CR3 and has been shown to promote adhesion of blood neutrophils to inflamed endothelium and restrict tissue infiltration. Therefore, LA-1 offers a novel mechanism of anti-inflammatory action by activation, rather than inhibition, of the neutrophil CR3 integrin. However, whether promotion of neutrophil-to-endothelial interaction by this novel therapeutic is of benefit or detriment to endothelial barrier function is not known. Methods: Critically ill septic and trauma patients were prospectively enrolled from the surgical and the trauma ICU. Blood was collected from these patients and healthy volunteers. Neutrophils were isolated by dextran sedimentation and adhered to TNF-alpha (tumor necrosis factor-alpha)-activated human umbilical vein endothelial (HUVEC) monolayers in the presence or absence of fMLP (formylmethionine-leucine-phenylalanine) and/or LA-1. Electric cell substrate impedance sensing (ECIS) and exposure of underlying collagen were used to quantify endothelial barrier function and permeability. Results: Neutrophils from critically ill trauma and septic patients caused similar degrees of endothelial barrier disruption which exceeded that caused by cells obtained from healthy controls both kinetically and quantitatively. LA-1 protected barrier function in the absence and presence of fMLP which served as a secondary stimulant to cause maximal loss of barrier function. LA-1 protection was also observed by quantifying collagen exposure underlying endothelial cells challenged with fMLP-stimulated neutrophils. LA-1 treatment resulted in decreased migration dynamics of neutrophils crawling on an endothelial monolayer with reduced speed (MUm/s = 0.25 +/- 0.01 vs. 0.06 +/- 0.01, p < 0.05), path length (MUm = 199.5 +/- 14.3 vs. 42.1 +/- 13.0, p < 0.05), and displacement (MUm = 65.2 +/- 4.7 vs. 10.4 +/- 1.3; p < 0.05). Conclusion: Neutrophils from patients with trauma or sepsis cause endothelial barrier disruption to a similar extent relative to each other. The CR3 agonist LA-1 protects endothelial barrier function from damage caused by neutrophils obtained from both populations of critically ill patients even when exposed to secondary stimulation. PMID- 29568529 TI - Prevalence of anemia before and after initiation of antiretroviral therapy among HIV infected patients at Black Lion Specialized Hospital, Addis Ababa, Ethiopia: a cross sectional study. AB - Background: Anemia is the most common hematological abnormality in Human immunodeficiency virus (HIV) positive patients and a significant predictor of its progression to AIDS or death. This study was aimed to assess the prevalence of anemia before and after initiation of antiretroviral therapy (ART) among HIV positive patients attending Black Lion Specialized Hospital, Addis Ababa, Ethiopia. Methods: A cross sectional study was conducted from January to April, 2017 in Black Lion Specialized Hospital, Addis Ababa, Ethiopia. A total of 255 patients on ART were selected using simple random sampling techniques. Socio demographic and clinical characteristics of the study subjects were collected using structured questionnaire. Measurements of complete blood cell counts and CD4 + T cell counts were made using Sysmex XT 2000i hematology analyzer and BD FACS Count CD4 analyzer, respectively. Statistical analysis of the data (Chi square, paired T-test, logistic regression) was done using SPSS version 20. A p value < 0.05 was considered as significant. Results: Prevalence of anemia before and after ART initiation was 41.9 and 11.4% respectively. There are a significance differences in CD4 + T cell count, RBC count, hemoglobin values and RBC indices in HIV patients before and after ART initiation (p-value < 0.05). WHO clinical stages and CD4+ T cell counts were found to be associated with the prevalence of anemia before ART initiation. Among the total number of anemic cases, normocytic normochromic anemia was present in 71% of the cases before ART and in 58.6% of the cases after ART. The prevalence of macrocytic normochromic anemia before and after ART initiation was 4.7 and 27.6% respectively. Conclusions: It is evident from this study that there is a remarkable reduction in the prevalence of anemia after ART initiation. However, a significant proportion of HIV patients remained anemic after 6 months of ART initiation suggesting the need for routine screening and proper treatment of anemia to mitigate its adverse effects. PMID- 29568528 TI - Achieving the earliest possible reperfusion in patients with acute coronary syndrome: a current overview. AB - Acute coronary syndrome (ACS) remains one of the leading causes of mortality worldwide. Appropriate management of ACS will lead to a lower incidence of cardiac arrest. Percutaneous coronary intervention (PCI) is the first-line treatment for patients with ACS. PCI techniques have become established. Thus, the establishment of a system of health care in the prehospital and emergency department settings is needed to reduce mortality in patients with ACS. In this review, evidence on how to achieve earlier diagnosis, therapeutic intervention, and decision to reperfuse with a focus on the prehospital and emergency department settings is systematically summarized. The purpose of this review is to generate current, evidence-based consensus on scientific and treatment recommendations for health care providers who are the initial points of contact for patients with signs and symptoms suggestive of ACS. PMID- 29568531 TI - Mycobacterium kansasii osteomyelitis - a masquerading disease. AB - Introduction: Non-tuberculous mycobacteria (NTM) are environmental bacteria capable of causing an opportunistic myriad of infections. Mycobacterium kansasii, one such NTM, is responsible for causing pulmonary disease in immunocompromised patients. Rare extrapulmonary manifestations such as lymphadenitis, osteoarticular manifestations, and skin and soft tissue infections are also observed. Case presentation: Here, we report an unusual case of sternoclavicular joint and elbow joint infection with M. kansasii in a relatively immunocompetent patient. Histopathology did not show classic granulomas and mycobacterial infection was not initially considered as a possibility. However repeat biopsies were sent for mycobacterial cultures which then grew M. kansasii. Conclusion: Diagnosis of M. kansasii in such cases can be difficult and culture-positive results may not necessarily imply positive diagnosis as they can be environmental contaminants. Furthermore, M. kansasii can cause infections without the characteristic granuloma formation, which can further complicate tissue diagnosis. This underlines the importance of ensuring that tissue samples obtained are cultured for mycobacteria. PMID- 29568530 TI - A case of Wohlfahrtiimonas chitiniclastica bacteremia in continental United States. AB - Introduction: Wohlfahrtiimonas chitiniclastica has been associated with open wound infections, cellulitis, osteomyelitis, and bacteremia. Case presentation: We report the case of a 41 year old woman with history of congenital myelomeningocele, paraplegia and extensive decubitus ulcers that developed W. chitiniclastica bacteremia secondary to an infected ulcer. Conclusion: W. chitiniclastica is an emerging human pathogen that can be readily identified by MALDI-TOF or sequencing. PMID- 29568532 TI - First case report of sepsis caused by Rhizobium pusense in Japan. AB - Introduction: Species of the genus Rhizobium are opportunistic, usually saprophytic, glucose-non-fermenting, Gram-negative bacilli found in agricultural soil. Rhizobium pusense infections are the least common Rhizobium infections and have low incidence. Case presentation: Herein, we report the first case of sepsis with R. pusense in Japan in a 67-year-old Japanese woman with a history of hyperlipidaemia, hypertension, diabetes, hypothyroidism and osteoporosis. She had undergone cerebrovascular treatment because she was diagnosed with a subarachnoid haemorrhage. The results of postoperative blood culture showed oxidase-positive, urease-positive, non-lactose-fermenting Gram-stain-negative rods. Using the Vitek2 system, the isolate was distinctly identified as Rhizobium radiobacter. However, 16S rRNA gene sequencing showed 99.93 % similarity with the type strain of R. pusense and 99.06 % similarity with the type strain of R. radiobacter. Additional gene sequencing analysis using recA (97.2 %) and atpD (96.2 %) also showed that the isolated strain is most closely related to R. pusense. The patient was cured by treatment using intravenous meropenem (3 g/d) for 4 weeks and was discharged safely. Conclusion: The definite source of sepsis was unknown. However, the possibility of having been infected through the catheter during the cerebrovascular operation was speculated. PMID- 29568533 TI - First confirmed case of nasal pythiosis in a horse in Thailand. AB - Introduction: Pythiosis is caused by Pythium insidiosum, a fungus-like organism in the class Oomycetes. It can infect humans and a variety of animal species in tropical, subtropical and some temperate regions. Cases of animal pythiosis have occurred predominantly in horses in the skin and subcutaneous tissue at the limbs and in the ventral portion of thoracoabdominal wall - lesions in the nasal region are rarely reported. Moreover, although many human pythiosis cases have been reported in Thailand, no cases of animal pythiosis in Thailand have been reported. Case presentation: We report a case of pythiosis in a horse infected at the nasal cavity. Diagnosis was performed by zoospore formation by bait technique, immunohistochemical stain, immunochromatography and sequence analysis. Conclusion: The sequences of rDNA were 99 % and 96 to 99 % identical to GenBank isolates of Pythium insidiosum from two Thai human patients and horses from various countries, respectively. This represents the first confirmed report of nasal equine pythiosis in Thailand. PMID- 29568534 TI - Ignavigranum ruoffiae, a rare pathogen that caused a skin abscess. AB - Introduction: Ignavigranum ruoffiae is an extremely rare cause of human infections. Case presentation: An 83-year-old male with a painless, ten-day-old, erythematous skin abscess on his left flank, which had showed a purulent discharge for 48 h, was admitted to the Emergency service. He was treated with cephalexin, disinfection with Codex water and spray of rifampicin. Five days later, surgical drainage of the abscess was proposed due to the torpid evolution of the patient. Samples were taken for culture, and antibiotic treatment with trimethoprim-sulfamethoxazole was established. The patient returned after 10 days showing healing of the abscess. Microbiological studies showed a few Gram positive cocci present as single cells and short chains that grew after 72 h of incubation at 35 degrees C with CO2 on 5 % sheep blood agar. Colonies presented a strong sauerkraut odour. Initial biochemical test results were negative for catalase, aesculin and bile-aesculin, and positive for pyrrolidonyl arylamidase, leucine aminopeptidase and growth in 6.5 % NaCl broth, which prompted the preliminary identification of Facklamia species or I. ruoffiae. The positive result for arginine deamination and negative result for hippurate hydrolysis, failure to produce acid from mannitol, sucrose, sorbitol or trehalose, plus the distinctive sauerkraut odour identified the organism as I. ruoffiae. The phenotypic identification was confirmed by 16S rRNA gene sequence analysis. The strain seemed to be susceptible to the antimicrobials tested but had decreased susceptibility to carbapenems. Conclusion: This case provides more insights into the phenotypic characteristics and antimicrobial resistance profile of I. ruoffiae. PMID- 29568535 TI - An operating room employee with a necrotic fingertip. PMID- 29568536 TI - Cerebellar cognitive affective syndrome: insights from Joubert syndrome. AB - Background: Joubert syndrome (JS) is a rare, autosomal recessively inherited genetic disorder characterized morphologically by unique developmental malformations of the cerebellum and brainstem (the molar tooth sign), and clinically by impaired motor functions and intellectual disability. Patients with JS often face multiple cognitive challenges, but the neuropsychological profile of this condition has not been well characterized. Methods: We performed comprehensive neurological and neuropsychological evaluations in three adult brothers with JS, ages 32, 27, and 25 years. Results: They all exhibited impaired motor control, global developmental delay most evident in executive function, affect regulation, and social skill set, and similar patterns of neuropsychiatric symptoms. Conclusions: These findings provide new insights into the intellectual and neurobehavioral phenotype of JS, which we regard as a developmental form of the cerebellar cognitive affective / Schmahmann syndrome (CCAS). These observations have direct clinical relevance for the diagnosis and care of patients with JS, and they help further the understanding of the multiple manifestations of atypical cerebrocerebellar development. PMID- 29568537 TI - A Province-wide, Cross-sectional Study of Demographics and Medication Use of Patients in Hemodialysis Units Across Ontario. AB - Background: Hemodialysis patients are at an increased risk of polypharmacy as they have the highest pill burden of all chronically ill patient populations, with an estimated average of 12 medications per day. Objectives: The aim of this study was to evaluate prescribing patterns of outpatient medications in patients receiving in-center hemodialysis. This was done to identify potential candidate medications for future quality improvement initiations to optimize prescribing. Design: We conducted a descriptive retrospective cross-sectional study in the province of Ontario, Canada, using several linked health care databases housed at the Institute for Clinical Evaluative Sciences (ICES). Setting: We considered outpatient medications dispensed to patients eligible for the Ontario Drug Benefit program. Patients: Patients were receiving chronic in-center hemodialysis at one of the 69 facilities in the province of Ontario, Canada as of October 1, 2013. Measurements: We assessed whether any of our 28 study medications of interest were recently dispensed (within the prior 120 days), the type of prescribing physician, and the associated medication costs. The 28 included medications of interest (ie, proton pump inhibitors, benzodiazepines) were selected because they may not have a true indication for dialysis patients and/or there are safety concerns with their use in this population. Results are presented as median (25th, 75th percentile). Methods: We conducted this study at ICES according to a prespecified protocol approved by the Research Ethics Board at Sunnybrook Health Sciences Centre (Toronto, Ontario). Results: A total of 3094 patients on chronic in-center hemodialysis received a study drug of interest (age: 76.5 years [SD: 7.3]), 44% women). Patients were dispensed 11 (8, 14) unique medication products with more than two-thirds of patients dispensed 9 or more different medications. The median number of annual health care visits was 7 (3-15) with more than half the cohort receiving prescriptions from 3 or more specialists. The 10 most commonly dispensed study medications cost more than 3 million dollars in direct costs in 1 year. Limitations: Our study was also subjected to some limitations of health care databases. Conclusions: Polypharmacy is frequent in in-center hemodialysis patients. To decrease polypharmacy and its associated negative outcomes, health care providers need to implement tools to optimize medication use and deprescribe medications that lack evidence for efficacy and safety in hemodialysis patients. Therefore, strategies to improve prescribing and discontinue ineffective medications warrant testing for better patient outcomes and reduced health care costs. PMID- 29568538 TI - Inhalation of hydrogen gas attenuates airway inflammation and oxidative stress in allergic asthmatic mice. AB - Background: Asthma is a worldwide common chronic airway disease that cannot be cured and results in the huge burden in public health. Oxidative stress was considered an important mechanism in the pathogenesis of asthma. Hydrogen gas been demonstrated to function as a novel antioxidant and exert therapeutic antioxidant activity in a number of diseases and the function of this nontoxic gas in asthma was unclear. The purpose of the study aims to examine the effect of inhalation hydrogen gas on the pathophysiology of a mouse model of asthma. Methods: A murine model of ovalbumin (OVA)-induced allergic airway inflammation was used in this study. Briefly, Mice were sensitized to ovalbumin and received inhalation of 67% high concentration of hydrogen gas for 60 min once a day for 7 consecutive days after OVA or PBS challenge respectively. Lung function was assessed in the apparatus with 4 channels of biological signal system. Morphology and goblet cell hyperplasia were stained by H/E and Periodic acid-Schiff staining. Cytologic classification in the bronchial alveolar lavage fluid (BALF) was analyzed by Wright Giemsa staining. Serum, BALF and lung tissue were collected for biochemical assay. One-way analysis of variance (ANOVA) was used to determine statistical significance between groups. Multiple comparisons were made by Bonferroni's Multiple Comparison Test by using GraphPad Prism 5 software. Results: Inhalation of hydrogen gas abrogated ovalbumin-induced the increase in lung resistance. Concomitantly, the asthmatic mice showed severe inflammatory infiltration and goblet cell hyperplasia which were reversed by hydrogen gas inhalation. Hydrogen gas inhalation reduced significantly the number of total cells, eosinophils and lymphocytes in BALF. Increased level of IL-4, IL-13, TNF alpha and CXCL15 in the BALF and IL-4 in the serum were decreased significantly after inhalation. Hydrogen gas inhalation markedly upregulated the activity of decreased superoxide dismutase and significantly attenuated the increased level of malondialdehyde and myeloperoxidase. Conclusions: Hydrogen gas inhalation improves lung function and protects established airway inflammation in the allergic asthmatic mice model which may be associated with the inhibition of oxidative stress process. This study provides a potential alternative therapeutic opportunity for the clinical management of asthma. PMID- 29568539 TI - Low level of knowledge about neonatal danger signs and its associated factors among postnatal mothers attending at Woldia general hospital, Ethiopia. AB - Background: Neonatal mortality has persisted high in Ethiopia in spite of many efforts being applied to decrease this adverse trend. Early detection of neonatal illness is an important step towards improving newborn survival. Toward this end, there is a need for the mothers to be able to identify signs in neonates that signify severe illnesses. The aim of this study was to assess knowledge about neonatal danger signs and its associated factors among postnatal mothers attending at Woldia general hospital, Ethiopian. Methods: Institutional based cross-sectional study design was conducted from January-May, 2017. The hospital that provides antenatal care (ANC), delivery, and postnatal services was purposively sampled. Structured interviewer managed questionnaire was administered to postnatal mothers attending Woldia general hospital. Frequencies, bivariate and multivariate logistic regression were determined using the SPSS software (Version 20). Results: During the study period 197 mothers attending postnatal care (PNC) service at Woldia general hospital were interviewed. Information on different neonatal danger signs was not provided to 92(46.7%) postnatal mothers during their antenatal clinic attendance by the healthcare providers. The majority of mothers, 174(88.3%) identified less than six neonatal danger signs. The hotness of the body of neonates was the commonly recognized danger sign by 106(53.8%) postnatal mothers. Of the total mothers, 67(34%), 60(30.5%), 56(28.4%), 44(22.3%) recognized unable to breastfeeding, convulsion, lethargy, difficulty in breathing as newly born danger signs, respectively. Out of 197 mothers, 32(16.2%) were giving birth at home. Mother's age(AOR = 1.33, 95% CI: 1.99-3.08), marital status(AOR = 2.50, 95% CI: 0.29-4.31), mother's education status(AOR = 3.48, 95% CI:1.57-8.72), husband's education(AOR = 4.92, 95% CI: 1.29-12.81), attending ANC (AOR = 2.88, 95% CI: 1.15, 4.85), mother's residence(AOR = 0.78, 95% CI: 0.47-1.65), information about neonatal danger signs(AOR = 3.48, 95% CI 1.40-9.49) had positive association with maternal level of knowledge to identify different neonatal danger signs. Conclusion: Maternal knowledge level about neonatal danger signs was very low. Therefore, intervention modalities that focus on increasing level of parental education, access to ANC and PNC service are needed. PMID- 29568540 TI - Developmental changes of fluconazole clearance in neonates and infants in relation to ontogeny of glomerular filtration rate: literature review and data analysis. AB - Background: Fluconazole is frequently prescribed for the treatment of systemic fungal infection in neonates and infants. At present, prediction of fluconazole doses according to developmental changes in fluconazole clearance is not being done in these patients. We aimed to formulate a developmental model of fluconazole clearance taking into account the ontogeny of renal function, since the drug is largely eliminated renally. Methods: We systematically retrieved the data of fluconazole pharmacokinetics and renal function in children and adults from databases (MEDLINE and Japan Medical Abstracts Society). Datasets were retrieved from individual children or groups from 9 studies comprising 55 neonates or infants at postmenstrual age (PMA) 27-58 weeks. Datasets were retrieved from 5 studies comprising 60 children and from 13 studies comprising 152 adults. Datasets of glomerular filtration rate (GFR) for individual pediatric subjects were retrieved from 4 studies comprising 187 neonates or infants. Results: Fluconazole clearance normalized to body surface area (BSA) (CLBSA) in neonates was 1/3 to 1/4 of adult values, but CLBSA increased rapidly during the neonatal and infantile periods and attained near adult values at PMA 60 weeks. A significant correlation between CLBSA and PMA was observed in neonates and infants: CLBSA (mL/min/m2) = 0.26? PMA (weeks) - 4.9 (r = 0.68, p < 0.001). In addition, the developmental time course of GFR normalized to BSA (GFRBSA) was fitted well to a sigmoidal model with the maximum GFRBSA of 149 mL/min/1.73m2, PMA associated with 50% of GFRBSA,max (PMA50) of 54 weeks, and the Hill coefficient of 3.7. A significant correlation between fluconazole clearance and GFR was found in neonates and infants: CL (mL/min) = 0.34?GFR (mL/min) - 0.53 (r = 0.84, p < 0.001). Assuming that plasma drug concentrations required for treating fungal infection are comparable between children and adults, fluconazole doses for pediatric patients with given PMAs may be predicted from adult doses (such as 100 mg/day) using size-normalized clearance as a scaling factor. The predicted doses for neonates and infants were largely within the ranges recommended in the prescribing information. Conclusions: The present study indicates that fluconazole doses for neonates and infants may be predicted from developmental change of systemic clearance, the ontogeny of which parallels the maturation of nephron function. PMID- 29568541 TI - Prevalence of feline immunodeficiency virus and feline leukaemia virus infection in Malaysia: a retrospective study. AB - Objectives: Feline ownership is popular and represents the largest segment of the pet population in Malaysia. Most feline owners own, on average, 2-3 cats, with some having >10 cats per household. Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are two clinically important viral infections in cats. Documenting the prevalence of these diseases in the feline population is important for both veterinarians and the public. Methods: This was a retrospective study, using data collected from the domestic cat population seen at a 24 h private veterinary hospital in Malaysia, to determine the prevalence of FIV and FeLV in an urban area and risk factors associated with these infections. Between 2010 and 2016, 2230 blood samples were collected and tested for FIV antibodies and FeLV antigen using commercially available ELISA test kits. Results: In total, 10.0% (n = 224; 95% confidence interval [CI] 8.80-11.26) were seropositive for FIV; 12.0% (n = 267; 95% CI 10.62-13.32) were seropositive for FeLV; and 2.6% (n = 58; 95% CI 2.01-3.17) were seropositive for both. Conclusions and relevance: The prevalence of FIV is lower and FeLV higher than previously documented for this region. Because of the immunosuppressive potential of both viruses, client education and use of appropriate control strategies such as routine screening, vaccination and eradication should be considered. PMID- 29568542 TI - Mammary fibroadenomatous hyperplasia in a male cat. AB - Case summary: Mammary fibroadenomatous hyperplasia (MFH) is a benign pathology characterised by extensive proliferation of the ductal epithelium and mammary stroma. It typically occurs in young female cats, and seems to result from hypersensitivity to progesterone. A 2-year-old entire male European Shorthair cat presented to the veterinary clinic with enlargement of several mammary glands, which had developed within the previous 10 days. There was no prior administration of progestin in the cat's medical history. Diagnostic tests were performed to assess the basal progesterone concentration and the concentration after stimulation with gonadotropin-releasing hormone, which ruled out the presence of functional ovarian tissue. Histological examination of the testes excluded hormone-secreting testicular tumours. Histological examination of the mammary gland confirmed the diagnosis of MFH. Treatment was started with aglepristone, a selective competitor for progesterone receptors, administered subcutaneously at 15 mg/kg at days 1, 2, 8 and 15. A reduction in the size of the mammary glands was evident 6 days after the first administration, with complete remission observed after 4 weeks. Relevance and novel information: To the best of our knowledge, this is the first full report of MFH in a male cat. Although the origin of the progestins responsible for MFH in this case could not be confirmed, in the light of the diagnostic tests performed and the results obtained, accidental contact with hormone-like substances seems to be the only plausible explanation for the cat's clinical signs. Inhibitor therapy was successful. PMID- 29568544 TI - No evidence of disease activity (NEDA) analysis by epochs in patients with relapsing multiple sclerosis treated with ocrelizumab vs interferon beta-1a. AB - Background: No evidence of disease activity (NEDA; defined as no 12-week confirmed disability progression, no protocol-defined relapses, no new/enlarging T2 lesions and no T1 gadolinium-enhancing lesions) using a fixed-study entry baseline is commonly used as a treatment outcome in multiple sclerosis (MS). Objective: The objective of this paper is to assess the effect of ocrelizumab on NEDA using re-baselining analysis, and the predictive value of NEDA status. Methods: NEDA was assessed in a modified intent-to-treat population (n = 1520) from the pooled OPERA I and OPERA II studies over various epochs in patients with relapsing MS receiving ocrelizumab (600 mg) or interferon beta-1a (IFN beta-1a; 44 MUg). Results: NEDA was increased with ocrelizumab vs IFN beta-1a over 96 weeks by 75% (p < 0.001), from Week 0-24 by 33% (p < 0.001) and from Week 24-96 by 72% (p < 0.001). Among patients with disease activity during Weeks 0-24, 66.4% vs 24.3% achieved NEDA during Weeks 24-96 in the ocrelizumab and IFN beta-1a groups (relative increase: 177%; p < 0.001). Conclusion: Superior efficacy with ocrelizumab compared with IFN beta-1a was consistently seen in maintaining NEDA status in all epochs evaluated. By contrast with IFN beta-1a, the majority of patients with disease activity early in the study subsequently attained NEDA status with ocrelizumab. PMID- 29568545 TI - Knowledge, attitude and practice of medical laboratory practitioners in the fight against Ebola virus disease. AB - Introduction: Ebola virus disease (EVD) in West Africa was an enormous public health challenge. Nigeria was able to contain the spread of the virus with a concerted effort and an effective public health response in terms of identification of contacts, rapid laboratory diagnosis, quarantine and symptomatic treatment. We determined the knowledge, attitude and practice of medical laboratory practitioners (MLPs) in this post-Ebola epidemic era. Methods: This cross-sectional study was carried out in eight hospitals in Kano State for 6 months, between January and June 2016. It involved medical laboratory scientists (MLS), medical laboratory technicians (MLT) and medical laboratory assistants (MLA). Questionnaires were administered and analysed. Results: Of the 75 participants, mean knowledge score was 5.54 (standard deviation [SD] +/-1.44) while the mean attitude score was 13.72 +/-2.80, and mean practice score was 3.10 +/-0.80. Mean age of participants was 36.82 +/- 8.07 years. There was full awareness of EVD among all 75 participants; however, many medical laboratory practitioners (52.7%) did not know EVD prevention methods. The majority (86.1%) knew the source of disease outbreak and most MLPs (66.7%) practised improper hand washing to prevent Ebola transmission. In addition, they had a negative attitude and practice towards EVD. Of 71 MLPs, 52 (73.2%) strongly disagreed that a traditional remedy was preferable in EVD treatment. Conclusion: Fear of EVD among MLPs has declined.

AB - Background: The benefits of calcium and vitamin D supplementation for low bone mass remains controversial. This study assessed the changes in bone mineral density (BMD) during periods without and with calcium and vitamin D supplementation among HIV-infected adolescents with low BMD. Method: Perinatally HIV-infected Thai adolescents aged 12-20 years were enrolled into Phase 1 (pre supplementation) to evaluate longitudinal change of BMD. We provided education about appropriate dietary intake and exercise. Lumbar spine (L2-L4) BMD and vitamin D status (25-hydroxyvitamin D [25(OH)D]) were assessed at baseline and at 12-24 month intervals. Participants with a BMD Z-score<=-2 were enrolled into Phase 2 (supplementation) that provided calcium 600 mg plus cholecalciferol 200 IU twice daily for 6 months. BMD and 25(OH)D were re-assessed at the end of study. Results: Ninety-four participants were enrolled into the Phase 1. Median age (IQR) was 14.3 (13.0-15.5) years, with 67% at Tanner stage 3-5, 89% with a plasma HIV-1 RNA<50 copies/mL. During Phase 1 and a 22.7-month follow-up, median L2-L4 BMD Z-scores remained unchanged (-1.06 vs -1.08, P=0.08), but 25(OH)D levels increased (24.7 vs 26.7 ng/mL, P=0.01). Twenty-six (28%) adolescents had low BMD and were enrolled into Phase 2, with 24 (92%) completing follow-up. The median L2-L4 BMD Z-scores (-2.59 vs -1.70; P<0.001) and calcium level (9.3 vs 9.5 mg/dL, P=0.04) significantly improved. There was an increase in BMD Z-scores during the 6-months post-supplementation as compared to the 21-month pre supplementation period (0.65 vs -0.50, P=0.03). Conclusion: HIV-infected adolescents with low BMD had improved bone health after calcium and vitamin D supplementation. A randomised controlled trial is warranted to confirm the benefits of these supplements. PMID- 29568547 TI - HIV rapid diagnostic testing by lay providers in a key population-led health service programme in Thailand. AB - Introduction: Rapid diagnostic testing (RDT) for HIV has a quick turn-around time, which increases the proportion of people testing who receive their result. HIV RDT in Thailand has traditionally been performed only by medical technologists (MTs), which is a barrier to its being scaled up. We evaluated the performance of HIV RDT conducted by trained lay providers who were members of, or worked closely with, a group of men who have sex with men (MSM) and with transgender women (TG) communities, and compared it to tests conducted by MTs. Methods: Lay providers received a 3-day intensive training course on how to perform a finger-prick blood collection and an HIV RDT as part of the Key Population-led Health Services (KPLHS) programme among MSM and TG. All the samples were tested by lay providers using Alere Determine HIV 1/2. HIV-reactive samples were confirmed by DoubleCheckGold Ultra HIV 1&2 and SD Bioline HIV 1/2. All HIV-positive and 10% of HIV-negative samples were re-tested by MTs using Serodia HIV 1/2. Results: Of 1680 finger-prick blood samples collected and tested using HIV RDT by lay providers in six drop-in centres in Bangkok, Chiang Mai, Chonburi and Songkhla, 252 (15%) were HIV-positive. MTs re-tested these HIV positive samples and 143 randomly selected HIV-negative samples with 100% concordant test results. Conclusion: Lay providers in Thailand can be trained and empowered to perform HIV RDT as they were found to achieve comparable results in sample testing with MTs. Based on the task-shifting concept, this rapid HIV testing performed by lay providers as part of the KPLHS programme has great potential to enhance HIV prevention and treatment programmes among key at-risk populations. PMID- 29568548 TI - Safety of lumbar puncture procedure in an international research setting during acute HIV infection. AB - Background: Cerebrospinal fluid (CSF) sampling at the time of acute HIV infection (AHI) is crucial in understanding NeuroAIDS pathogenesis. Here, we report on the safety of performing a lumbar puncture (LP) during untreated AHI and follow-up after initiation of combination antiretroviral therapy (cART). Methods: We reviewed clinical records of participants who took part in an AHI protocol in Bangkok, Thailand, including untreated AHI subjects (baseline), and longitudinal visits following immediate initiation of cART to assess rates and risk of post lumbar puncture headaches (PLPH). A cerebrospinal fluid (CSF) volume of 10-20 mL was collected using standard cutting-edge or atraumatic needles. Results: From April 2009 to February 2016, 195 LPs were performed, of which 89 (46%) were at baseline. The LP procedures at baseline were not associated with an additional PLPH risk as compared to repeat LPs after cART initiation (26/89 [29%] vs 4/27 [15%], respectively; P=0.134). Higher body mass index (BMI) at baseline (P=0.070) and use of an atraumatic needle (P=0.058) had trend-level associations with reduced PLPH. A higher CSF volume collection (20 mL) was independently associated with a lower PLPH frequency (P=0.024). This association was similar in a subgroup analysis with the use of atraumatic needles. The CD4+ T lymphocyte count, blood and CSF HIV viral load, Fiebig staging, and the presence of an acute retroviral syndrome did not correlate with risk for PLPH (all P>0.05). Conclusion: The frequency of PLPH during AHI was similar to that seen in the setting of cART treated HIV infection and not higher with a larger CSF volume collection. Our study adds to the existing evidence that atraumatic needles should be used to minimise the risk of PLPH. PMID- 29568549 TI - Markers of subclinical atherosclerotic disease in HIV-infected individuals. AB - Background: Wider access to antiretroviral treatment (ART) has resulted in a decline in the number of people dying due to AIDS-related causes. However, with this increased longevity, accelerated rates of cardiovascular and atherosclerotic diseases are on the rise. We hypothesised that the prevalence of atherosclerotic cardiovascular diseases is greater in HIV/AIDS patients as compared to the normal population. Thus, we aimed to study the predictors of subclinical atherosclerotic disease in HIV-infected individuals. Methods: In total, 168 HIV-positive individuals below 45 years of age (124 [73.08%] on ART and 44 [26.2%] ART naive) along with 150 age- and sex-matched healthy controls were recruited for this cross-sectional observational study. Carotid intimal medial thickness (cIMT), a surrogate marker of atherosclerosis, was assessed by a carotid colour doppler ultrasound and a mean of four measurements (both sides) were taken. cIMT was correlated with the age of the individuals, duration and type of ART, duration of disease and the level of immunodeficiency (CD4 cell count) along with conventional cardiac risk markers. Results: In 168 HIV-positive individuals, the mean CD4 cell count was 332.41 +/-17.1 cells/mm3. The mean cIMT of all HIV positive individuals was 0.712 +/-0.039 mm (0.596-0.840 mm) as compared to 0.616 +/-0.023 mm (0.540-0.655 mm) in HIV-negative individuals (P<0.001). cIMT in HIV positive individuals on ART (subgroup A) was 0.723 +/-0.034 mm as compared to 0.682 +/-0.038 mm in HIV-positive individuals not on ART (subgroup B) (P<0.01). Low CD4 cell counts, longer duration of HIV infection, exposure to ART and longer duration of ART were found to be independent predictors of a higher cIMT in HIV positive subjects whereas age, diastolic blood pressure, low HDL, smoking and high BMI were predictors of high cIMT in HIV-negative controls. No difference was observed in cIMT among patients on different ART regimens but individuals who were on nevirapine had higher cIMT as compared to those who were on efavirenz, both non-nucleoside reverse transcriptase inhibitors (NNRTIs). Conclusions: Individuals with HIV infection (whether on ART or ART naive) have higher cIMT, and therefore a higher atherosclerotic burden, as compared to HIV-negative individuals. HIV infection itself, along with ART, overshadows conventional cardiac risk markers as a predictor of atherosclerotic disease in these individuals. PMID- 29568550 TI - Dermatological conditions associated with HIV medication in a cohort of Greek patients initiating antiretroviral therapy: 1988-2013. AB - Objectives: Treatment of HIV infection has evolved from a single antiretroviral agent to combination therapy, which has dramatically improved both the quality of life and life expectancy of affected patients. The aim of this study was to review HIV treatment-associated dermatological conditions observed in adult patients receiving antiretroviral therapy (ART) in a single tertiary care referral centre over time. Methods: We reviewed the files of HIV-positive patients seen at the Dermatology Department, AIDS Clinic of the Andreas Syggros Hospital, Athens, Greece who had initiated ART from 1988 to 2013, for evidence of dermatological conditions commonly associated with HIV-related medication. Results: Among a cohort of 1329 HIV-positive patients (1155 men and 174 women), 352 (299 men and 53 women) presented with at least one dermatological condition, with a total of 423 conditions diagnosed that could be attributed to HIV-related medication. Lipodystrophy (47.42%), and maculopapular (MP) rash (40.6%) were most commonly diagnosed. There were three incidence peaks for these reactions, which reflected the different types of ART and HIV-related drugs commonly used at the time. After 2006, the number of these dermatological conditions declined (15.1% of cases) with the availability of newer ART regimens. Conclusions: Early ART was accompanied with a high incidence of adverse skin reactions, which have decreased over time in association with overall better tolerated treatment regimens for HIV infection. PMID- 29568551 TI - Crowdsourcing and community engagement: a qualitative analysis of the 2BeatHIV contest. AB - Background: As HIV cure research advances, it is important to engage local communities. Crowdsourcing may be an effective, bottom-up approach. Crowdsourcing contests elicit public contributions to solve problems and celebrate finalists. We examine the development of a crowdsourcing contest to understand public perspectives about HIV cure research. Methods: We used flyers, emails, online advertisement and phone calls to recruit a convenience sample of community members to participate in focus-group discussions. Participants developed a contest name, logo and hashtag. Qualitative analysis identified emergent themes in the focus group transcripts. Results: Seventy-one people participated in four focus groups. Emergent themes for HIV cure engagement included: (1) emphasising collective approaches to HIV cure; (2) dispelling myths to spur discussion; (3) using HIV cure as motivation for participation; and (4) using creative community engagement. Conclusion: Crowdsourcing contests may be useful for engaging local communities, developing culturally tailored awareness campaign messaging, and encouraging the public to learn more about HIV cure research. PMID- 29568552 TI - Prevalence and factors associated with renal dysfunction in patients on tenofovir disoproxil fumarate-based antiretroviral regimens for HIV infection in Southern India. AB - Objectives: Tenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor commonly used in the treatment of HIV infection. This retrospective study aims to establish the prevalence of abnormal renal function among patients with HIV receiving TDF, and to investigate the risks for TDF related renal dysfunction in this population. Methods: Patients at the YRGCARE Medical Centre, Voluntary Health Services, receiving TDF-containing antiretroviral (ART) regimens between January 2002 and March 2017, were assessed for renal dysfunction using creatinine level and eGFR (DAIDS/NIH) during continuum of care. Demographic data and comorbidities were analysed for association with TDF toxicity. Data were obtained from the Natural History Study Database. Other causes of renal dysfunction were excluded. Results: From the 14,118 patients on ART between 2002 and 2017 seen in the clinic, 7171 (50.8%) were initiated on TDF-containing regimens. Among these, 4400 were on a first-line NNRTI regimen, and 2771 on a second-line PI/r regimen, initiated after failure of first-line therapy. The majority of patients on ART were male, with a median age for the whole sample of 36 years (IQR 30-42). At ART initiation, the median CD4 cell count was 277 cells/mm3 (IQR 165-421) and the viral load (VL) 31,198 HIV-1 copies/mL (IQR 400-226,690). Median duration of follow-up was 5.1 years (IQR 2.3 9.5). The prevalence of renal dysfunction in patients taking TDF was 5.6%. Increased age, low BMI, low baseline CD4 cell count, hypertension and diabetes were associated with tenofovir toxicity (P<0.05). Concomitant PI use was not associated with increased risk for renal dysfunction (P>0.05). Conclusions: The prevalence of renal dysfunction associated with TDF in our study population was higher than in other well-resourced settings, suggesting the need for increased renal parameter monitoring in patients in resource-limited settings. Treatment with ART should be initiated earlier and BMI should be maintained >=18.5 kg/m2 through adequate nutrition and prevention of opportunistic infections. For patients with multiple comorbidities, tenofovir alafenamide (TAF) should be considered, instead of TDF, to avoid renal dysfunction. PMID- 29568553 TI - HIV-associated cognitive performance and psychomotor impairment in a Thai cohort on long-term cART. AB - Objectives: To assess cognitive performance and psychomotor impairment in an HIV positive cohort, well-suppressed on combination antiretroviral therapy (cART), in an Asian resource-limited setting. Methods: Cross-sectional sociodemographic and cognitive data were collected in 329 HIV-positive and 510 HIV-negative participants. Cognitive performance was assessed using the International HIV Dementia Scale (IHDS), Montreal Cognitive Assessment (MoCA), WAIS-III Digit Symbol, Trail Making A, and Grooved Pegboard (both hands). Psychomotor test scores in the HIV-positive participants were converted to Z-scores using scores of the HIV-negative participants as normative data. Psychomotor impairment was defined as performance on two tests more than 1 standard deviation (SD) from controls or more than 2 SD on one test. Multivariate linear and logistic regression analyses were used to investigate associations between HIV and non-HIV related covariates and poorer cognitive performance and psychomotor impairment. Results: HIV-positive participants, mean age 45 (SD 7.69) years received cART for a median of 12.1 years (interquartile range [IQR] 9.1-14.4). Median CD4 cell count was 563 cells/mm3 (IQR 435-725), and 92.77% had plasma HIV RNA <40 copies/mL. The adjusted mean differences between HIV-positive versus HIV-negative cohorts indicated significantly inferior cognitive performance (tests all P<0.001) with increasing age and lower income, independently associated. Psychomotor impairment was found (P<0.02) in all tests except the Grooved Pegboard non-dominant hand (P=0.48). Psychomotor impairment prevalence was 43% in the HIV-positive cohort, associated with male gender and lower income. Conclusions: In this study, in individuals with viral suppression rates >90% on long-term cART, we found that inferior cognitive performance and psychomotor impairment were primarily associated with non-HIV-related factors. PMID- 29568554 TI - Highlights from the HTLV-1 symposium at the 2017 Australasian HIV and AIDS Conference held jointly with the 2017 Australasian Sexual Health Conference, November 2017, Canberra, Australia. AB - We are pleased to report on the inaugural HTLV-1 symposium at the 2017 Australasian HIV and AIDS Conference joint with 2017 Australasian Sexual Health Conference in Canberra, Australia. Our understanding of HTLV-1 epidemiology, pathogenesis, laboratory diagnostics and treatment options for HTLV-1 diseases has advanced tremendously over the last 40 years. However, the awareness of healthcare providers and the general population about HTLV-1, and the effective promotion and implementation of HTLV-1 transmission-prevention strategies, lag behind current knowledge. Here we present a summary of the symposium, plenary and poster presentations on HTLV-1.

PMID- 29568556 TI - Highlights from the HIV Cure and Reservoir Symposium, 11-12 September 2017, Ghent, Belgium. AB - For the second time, the HIV Cure Research Center (HCRC) at Ghent University organised the HIV Cure and Reservoir Symposium, in Ghent, Belgium, where in this two-day conference, virologists, molecular biologists, immunologists and clinicians presented the most recent achievements in the field of HIV cure, including data on therapeutic vaccines, HIV remission strategies such as 'shock and kill' or 'block and lock', benefits of early ART and potential of haematopoietic stem cell transplant in achieving cure. Furthermore, methods to characterise and quantify the HIV reservoir were discussed along with HIV reservoir characterisation in different body parts, including the central nervous system. An HIV activist and representative of a patients' agency also presented the patients' perspective on HIV cure. This report is a summary of all topics discussed during this symposium.

We suggest that artwork provided by the general public could have a role in campaigns promoting hepatitis elimination. PMID- 29568559 TI - Unconscionable: how the U.S. Supreme Court's jurisprudence lags behind the world when it comes to contraception and conscience. AB - U.S. Supreme Court jurisprudence undermines access to contraception by permitting individuals, institutions, and even corporations to claim religious objections to ensuring contraceptive insurance coverage, thus imposing those beliefs on non adherents and jeopardizing their access to essential reproductive-health services. This jurisprudence is not only harmful but also runs contrary to the laws and policies of peer nations, as well as international human rights principles, which are more protective of the rights of health-care recipients to make their own decisions about contraception free from interference. The United States should look to the practice and jurisprudence of other nations and ensure that religious exemptions are not permitted to deprive a third party of access to contraception.

AB - Background: Lubricin is chondrocyte-secreted glycoprotein that primarily conducts boundary lubrication between joint surfaces. Besides its cytoprotective function and extracellular matrix (ECM) attachment, lubricin is recommended as a novel biotherapeutic protein that restore functional articular cartilage. Likewise, malfunction of lubrication in damaged articular cartilage caused by complex and multifaceted matter is a major concern in the field of cartilage tissue engineering. Main body: Although a noticeable progress has been made toward cartilage tissue regeneration through numerous approaches such as autologous chondrocyte implantation, osteochondral grafts, and microfracture technique, the functionality of engineered cartilage is a challenge for complete reconstruction of cartilage. Thus, delicate modulation of lubricin along with cell/scaffold application will expand the research on cartilage tissue engineering. Conclusion: In this review, we will discuss the empirical analysis of lubricin from fundamental interpretation to the practical design of gene expression regulation.

AB - Aim: Fascin is a 55 kDa globular protein with an important role in cell migration. Aim of study was to investigate serum fascin in healthy males. Materials & methods: From 1 July 2016 to 31 December 2016, we collected serum from 46 males. Serum fascin level was performed using ELISA kit from USBiological (Salem, MA, USA). Results: Median age was 64 years. Mean fascin serum level was 9.84 ng/ml, mean prostate-specific antigen (PSA) was 2.74 ng/ml and mean prostate volume was 37.64 cc. The 51-60 years group had a mean of 10.53 ng/ml, the 61-70 group a mean of 9.7 ng/ml and the 71-80 group had a mean of 9.41 ng/ml fascin serum level. Conclusion: Fascin serum level did not differ according to age in males. PMID- 29568563 TI - A future perspective for regenerative medicine: understanding the concept of vibrational medicine. PMID- 29568564 TI - Antibodies, synthetic peptides and related constructs for planetary health based on green chemistry in the Anthropocene. AB - The contemporary Anthropocene is characterized by rapidly evolving complex global challenges to planetary health vis-a-vis sustainable development, yet innovation is constrained under the prevailing precautionary regime that regulates technological change. Small-molecule xenobiotic drugs are amenable to efficient large-scale industrial synthesis; but their pharmacokinetics, pharmacodynamics, interactions and ultimate ecological impact are difficult to predict, raising concerns over initial testing and environmental contamination. Antibodies and similar agents can serve as antidotes and drug buffers or vehicles to address patient safety and decrease dosing requirements. More generally, peptidic agents including synthetic peptide-based constructs exemplified by vaccines can be used together with or instead of nonpeptidic xenobiotics, thus enabling advances in planetary health based on principles of green chemistry from manufacturing through final disposition. PMID- 29568565 TI - Evaluation of CYP2C9- and VKORC1-based pharmacogenetic algorithm for warfarin dose in Gaza-Palestine. AB - Aim: To evaluate applicability of CYP2C9*2, *3 and VKORC1-1639G > A based algorithm to predict warfarin stable dose (WSD) in a group of Palestinian patients. Patients & methods: Warfarin doses were retrospectively calculated for 101 Palestinian patients under warfarin therapy using three models. Performance of the three models was assessed in 47 patients found to take WSD. Results: Frequency of CYP2C9*2, *3 and VKORC1-1639G > A alleles is 13.6, 0.0 and 46.5% respectively. The international warfarin pharmacogenetics consortium algorithm was more reliable (MAE = 8.9 +/- 1.4; R2 = 0.350) than both the clinical algorithm (MAE = 10.4 +/- 1.4; R2 = 0.128;) and the fixed-dose algorithm (MAE = 11.1 +/- 1.7). Conclusion: The international warfarin pharmacogenetics consortium algorithm can be reliably applied for predicting the WSD in Palestinian population. PMID- 29568566 TI - Could dietary glutamate be contributing to the symptoms of obsessive-compulsive disorder? AB - A 50-year-old man who had suffered from daily obsessive-compulsive disorder (OCD) symptoms for 39 years, in addition to fibromyalgia and irritable bowel syndrome symptoms, was enrolled in a randomized double-blind placebo-controlled clinical trial to test the effects of a low-glutamate diet on fibromyalgia/irritable bowel syndrome symptoms. After 1 month on the low-glutamate diet all of his symptoms remitted, including his OCD, which had previously been nonresponsive to pharmacological treatment. This case study is limited by self-report of symptoms; however, glutamatergic neurotransmission appears to be dysregulated in OCD, suggesting biological plausibility for this observation. Future research is needed. PMID- 29568568 TI - Series of screening compounds with high hit rates for the exploration of multi target activities and assay interference. AB - Aim: Generation of a database of analog series (ASs) with high assay hit rates for the exploration of assay interference and multi-target activities of compounds. Methodology: ASs were computationally extracted from extensively tested screening compounds with high hit rates. Data: A total of 6941 ASs were assembled comprising 14,646 unique compounds that were tested in a total of 1241 different assays covering 426 specified targets. These ASs were organized and prioritized on the basis of different activity and assay frequency criteria. All ASs and associated information are made available in an open access deposition. Next steps: The large set of ASs will be further analyzed computationally and from a chemical perspective to identify assay interference compounds and candidates for exploring target promiscuity. PMID- 29568567 TI - Key genes and regulatory networks involved in the initiation, progression and invasion of colorectal cancer. AB - Aim: Until now, identification of drug targets for treatment of patients with specific stages of colorectal cancer (CRC) has remained a challenging field of research. Herein, we aimed to identify the key genes and regulatory networks involved in each stage of CRC. Results: The results of gene expression profiles were integrated with protein-protein interaction networks, and topologically analyzed. The most important regulatory genes (e.g., CDK1, UBC, ESR1 and ATXN1) and signaling pathways (e.g., Wnt, MAPK and JAK-STAT) in CRC initiation, progression and metastasis were identified. In vitro analysis confirmed some in silico findings. Conclusion: Our study introduces functional hub genes, subnetworks, prioritizes signaling pathways and novel biomarkers in CRC that may guide further development of targeted therapy programs. PMID- 29568569 TI - Polysaccharide-mediated synthesis of melanins from serotonin and other 5-hydroxy indoles. AB - Aim: As a continuation of our research on the melanin formation from catecholamines, we studied the polysaccharide-mediated oxidation of serotonin and other 5-hydroxy indoles into melanin-like materials. As for the catecholamines, we observed that many polysaccharides promote the oxidation of such compounds, particularly in the presence of Cu2+. Methodology: The reactions were monitored using reverse phase-HPLC and size-exclusion chromatography techniques. Melanin like materials were purified through dialysis and characterized using UV-Vis and Fourier transform IR spectroscopic techniques. Results: One such material, synthesized from chondroitin sulfate type A and serotonin in the presence of Cu2+ was found to affect the release of IL-1beta and IL-6 cytokines from immune cells.

PMID- 29568571 TI - Analysis of cytomegalovirus-specific T-cell responses in patients with hypertension: comparison of assay methods and antigens. AB - Background: Recent studies suggest an association between cytomegalovirus (CMV) infection and hypertension. In the present study, we used a variety of antigens and different assay methods to investigate the relationship between CMV-specific T-cell responses and arterial stiffness in patients with hypertension. Methods: To evaluate arterial stiffness, pulse wave velocity (PWV) was measured in 207 hypertensive patients (average age, 63 +/- 8 years). To measure CMV pp65 and IE-1 specific T-cell responses, we performed intracellular cytokine staining (ICS) and enzyme-linked immunospot (ELISPOT) assays. We also analyzed CMV-specific T-cell responses against 10 different CMV antigens using ELISPOT assays. Results: In patients with hypertension, senescent CD8+ T-cell frequencies were significantly correlated with arterial stiffness. Moreover, arterial stiffness was independently associated with CMV pp65-specific CD8+ T-cell responses as measured by ICS. CMV-specific CD8+ T-cell responses measured by ICS and ELISPOT assays showed good agreement and significant correlation with each other. ELISPOT analyses against 10 different CMV antigens revealed a consistent response pattern irrespective of age, gender, and diabetes. Conclusions: CMV pp65-specific CD8+ T cell responses were independently correlated with arterial stiffness in patients with hypertension. Additionally, the results of ICS and ELISPOT assays showed a significant correlation and good agreement with each other. These findings are important for guiding choices regarding the broad clinical application of CMV specific T-cell response assays in this patient population. PMID- 29568572 TI - Vitreous changes after intravitreal bevacizumab monotherapy for retinopathy of prematurity: a case series. AB - Purpose: Reporting a special clinical finding after intravitreal bevacizumab monotherapy for retinopathy of prematurity. Methods: In a retrospective case series, the clinical courses of five premature infants with similar vitreous changes after a single dose of intravitreal bevacizumab (IVB) injection without additional laser therapy were reported. Results: The mean post-conceptional age at IVB injection was 39.8 +/- 2.2 (range 37-43) weeks. Localized vitreous syneresis and linear fibrotic vitreous condensation occurred 8.2 +/- 2.3 weeks after IVB monotherapy in our patients (15.5% of injections). The mean last post injection visit was 61.6 +/- 5.3 weeks (post-conceptional age). Further regression and complete retinal vascularization occurred in all patients. Conclusions: Thread-like vitreous condensation with localized vitreous liquefaction may be related to involutional ROP disease itself, combined to anti VEGF therapy and may be a predictor factor for further regression and retinal vascularization. The case series describes a successful response to anti-VEGF monotherapy with no further complications. PMID- 29568573 TI - In vitro multichannel single-unit recordings of action potentials from mouse sciatic nerve. AB - Electrode arrays interfacing with peripheral nerves are essential for neuromodulation devices targeting peripheral organs to relieve symptoms. To modulate (i.e., single-unit recording and stimulating) individual peripheral nerve axons remains a technical challenge. Here, we report an in vitro setup to allow simultaneous single-unit recordings from multiple mouse sciatic nerve axons. The sciatic nerve (~30 mm) was harvested and transferred to a tissue chamber, the ~5mm distal end pulled into an adjacent recording chamber filled with paraffin oil. A custom-built multi-wire electrode array was used to interface with split fine nerve filaments. Single-unit action potentials were evoked by electrical stimulation and recorded from 186 axons, of which 49.5% were classed A-type with conduction velocities (CV) greater than 1 m/s and 50.5% were C-type (CV < 1 m/s). The single-unit recordings had no apparent bias towards A- or C-type axons, were robust and repeatable for over 60 minutes, and thus an ideal opportunity to assess different neuromodulation strategies targeting peripheral nerves. For instance, ultrasonic modulation of action potential transmission was assessed using the setup, indicating increased nerve conduction velocity following ultrasound stimulus. This setup can also be used to objectively assess the design of next-generation electrode arrays interfacing with peripheral nerves. PMID- 29568574 TI - Visual loss in HIV-associated cryptococcal meningitis: A case series and review of the mechanisms involved. AB - Permanent visual loss is a devastating yet preventable complication of cryptococcal meningitis. Early and aggressive management of cerebrospinal fluid pressure in conjunction with antifungal therapy is required. Historically, the mechanisms of visual loss in cryptococcal meningitis have included optic neuritis and papilloedema. Hence, the basis of visual loss therapy has been steroid therapy and intracranial pressure lowering without clear guidelines. With the use of high-resolution magnetic resonance imaging of the optic nerve, an additional mechanism has emerged, namely an optic nerve sheath compartment syndrome (ONSCS) caused by severely elevated intracranial pressure and fungal loading in the peri optic space. An improved understanding of these mechanisms and recognition of the important role played by raised intracranial pressure allows for more targeted treatment measures and better outcomes. In the present case series of 90 HIV co infected patients with cryptococcal meningitis, we present the clinical and electrophysiological manifestations of Cryptococcus-induced visual loss and review the mechanisms involved. PMID- 29568575 TI - Neuroendocrine tumour in a patient with neurofibromatosis type 1 and HIV. AB - We report the case of an HIV-positive female patient with neurofibromatosis type 1 who was treated for recurrent peptic ulcer disease and later developed diabetes mellitus and chronic diarrhoea. A metastasising somatostatinoma was histologically proven and evidence of a concomitant gastrin-producing neuroendocrine tumour was found. Neuroendocrine tumours (NETs) are very rare neoplasms originating from a wide variety of endocrine and nervous system tissue with the ability to produce different hormones. A somatostatin- and gastrin secreting NET in a patient with HIV has not been reported in the literature, to the best of our knowledge. We discuss oncogenic pathomechanisms related to the underlying conditions and propose stringent monitoring for tumours in HIV positive patients with phakomatoses as well as initiation of antiretroviral therapy. PMID- 29568576 TI - New law on HIV testing in Botswana: The implications for healthcare professionals. AB - Background: Botswana is one of the countries with the highest HIV prevalence rates in the world. Innovative HIV testing strategies are required to ensure that those infected or at risk of infection become aware of their HIV status and are able to access treatment, care and support. Despite this public health imperative, HIV testing strategies in Botswana will in future be based around the principles in the new Public Health Act (2013). The present article describes the HIV testing norms in the Act, and sets out the strengths and weaknesses of this approach and its implications for healthcare professionals in Botswana. Objectives: To compare international norms on HIV testing with the provisions governing such testing in the new Botswana Public Health Act and to assess the extent to which the new Act meets international human rights norms on HIV testing. Method: A 'desktop' review of international human rights norms and those in the Botswana Public Health Act. Conclusion: HIV testing norms in the new Public Health Act in Botswana violate individual rights and will place healthcare workers in a position where they will have to elect between acting lawfully or ethically. Law reform is required in order to ensure that HIV testing achieves the joint goals of public health and human rights. PMID- 29568577 TI - Evaluation of selected aspects of the Nutrition Therapeutic Programme offered to HIV-positive women of child-bearing age in Western Cape Province, South Africa. AB - Background: The Nutrition Therapeutic Programme (NTP) involves the provision of food supplements at primary health clinics (PHCs) to correct nutritional deficiencies in vulnerable groups. Although previous studies have identified problems with implementing the programme at PHCs, assessments of its efficiency have been scarce. Objective: To evaluate implementation of the NTP at PHCs that provide antiretroviral therapy. Methods: A cross-sectional, descriptive study was conducted at 17 PHCs located within 3 districts of Western Cape Province. Two target groups were chosen: 32 staff members working at the sites and 21 women of child-bearing age enrolled in the NTP. Questionnaires were used to obtain data. Results: Only 2 women (10%) lived in food-secure households; the rest were either at risk of hunger (29%) or classified as hungry (61%). Most of the women knew they had to take the supplements to improve their nutritional status, but the majority only recalled receiving basic nutritional advice, and the information was mainly given verbally. Ten of the women had shared their supplements with others, mostly with their children. The study identified lack of clearly defined NTP responsibilities at the PHCs, causing confusion amongst the staff. Although many staff members expressed problems with the NTP, only 38% of them reported having routine evaluations regarding the programme. Conclusion: Several aspects compromised the effectiveness of the NTP, including socio-economic factors leading to clients' non-compliance. The strategic organisation and implementation of the NTP varied between different PHCs offering antiretroviral therapy, and staff experienced difficulties with the logistics of the programme. PMID- 29568578 TI - Gestational trophoblastic neoplasm and women living with HIV and/or AIDS. AB - The 2011 World Health Organization global report on HIV and/or AIDS estimated that sub-Saharan Africa comprised 67% of the global HIV burden, with a current estimate of 5.9 million cases in South Africa. Since the introduction of antiretroviral therapy, there has been an increase in the incidence of non-AIDS defining cancers. Gestational trophoblastic neoplasm (GTN) is a rare pregnancy related disorder with an incidence ranging from 0.12-0.7/1000 pregnancies in Western nations. The overall cure rate is about 90%. Response to treatment for GTN is generally favourable; but the sequelae of HIV and/or AIDS, the resultant low CD4 counts, comorbidities, poor performance status and the extent of metastatic disease in patients receiving chemotherapy, compromise the prognosis and survival. PMID- 29568579 TI - Impact of combination antiretroviral therapy initiation on adherence to antituberculosis treatment. AB - Background: Healthcare workers are often reluctant to start combination antiretroviral therapy (ART) in patients receiving tuberculosis (TB) treatment because of the fear of high pill burden, immune reconstitution inflammatory syndrome, and side-effects. Object: To quantify changes in adherence to tuberculosis treatment following ART initiation. Design: A prospective observational cohort study of ART-naive individuals with baseline CD4 count between 50 cells/mm3 and 350 cells/mm3 at start of TB treatment at a primary care clinic in Johannesburg, South Africa. Adherence to TB treatment was measured by pill count, self-report, and electronic Medication Event Monitoring System (eMEMS) before and after initiation of ART. Results: ART tended to negatively affect adherence to TB treatment, with an 8% - 10% decrease in the proportion of patients adherent according to pill count and an 18% - 22% decrease in the proportion of patients adherent according to eMEMS in the first month following ART initiation, independent of the cut-off used to define adherence (90%, 95% or 100%). Reasons for non-adherence were multifactorial, and employment was the only predictor for optimal adherence (adjusted odds ratio 4.11, 95% confidence interval 1.06-16.0). Conclusion: Adherence support in the period immediately following ART initiation could optimise treatment outcomes for people living with TB and HIV. PMID- 29568580 TI - Factors associated with retention in HIV care at Sediba Hope Medical Centre. AB - Background: Lost to follow-up (LTFU) is a major challenge that hinders the success of antiretroviral treatment (ART). Objective: To identify factors conducted to a low LTFU rate. Methods: We conducted a two-part descriptive and quantitative study. Part 1 comprised interviews with clinic staff to determine their perspectives on LTFU and to establish the clinic's follow-up procedures for patients on ART. Part 2 of the study was a retrospective review of clinic and patient records. LTFU patients were identified and those with contact details were contacted for telephonic interview to determine if they were still on ART and/or their reasons for becoming LTFU. Results: A low LTFU rate (7.9%; N = 683) was identified. Work-related stress, and lack of transport and funds were reported reasons for LTFU. Monthly visits, non-adherent defaulters and LTFU patients were tracked by an electronic system (SOZO). Factors contributing to high rates of retention in care were: location of the clinic in the inner city, thus in close proximity to patients' homes or work; clinic operating on Saturdays, which was convenient for patients who could not attend during the week; an appointment/booking system that was in place and strictly adhered to; a reminder SMS being sent out the day before an appointment; individual counselling sessions at each visit and referrals where necessary; and a stable staff complement and support group at the clinic. Conclusion: Achieving a low LTFU rate is possible by having a patient-centred approach and monitoring systems in place. PMID- 29568581 TI - A case of emmonsiosis in an HIV-infected child. AB - Opportunistic fungal infections can cause significant morbidity and mortality in immunocompromised patients. We describe a paediatric case of an unusual disseminated fungal infection. A three-year-old HIV-infected child with severe immunosuppression (CD4+ T-cell count 12 * 106/L) was admitted to hospital with pneumonia, gastroenteritis and herpes gingivostomatitis. Despite antibacterial and antiviral therapy, he experienced high fevers and developed an erythematous maculopapular rash and abdominal tenderness. The child's condition progressively worsened during the admission. A thermally dimorphic fungus was cultured from bone marrow and identified as an Emmonsia species on DNA sequencing. The patient made a good recovery on amphotericin B deoxycholate and antiretroviral therapy. Itraconazole was continued for a minimum of 12 months, allowing for immune reconstitution to occur. This case is the first documented description of disseminated disease caused by a novel Emmonsia species in an HIV-infected child in South Africa. PMID- 29568582 TI - Choice or no choice? The need for better branded public sector condoms in South Africa. AB - Condoms are one of the cornerstones to any response to the HIV epidemic. However, targeted marketing strategies that make condoms more attractive to people at high risk of infection are often overlooked. The South African National Department of Health has recently purchased more attractive condoms to distribute in higher education settings free of charge, targeting at-risk youth including young women. The authors applaud this move but note the importance of expanding better branded condoms to young people elsewhere - for example, via youth clinics and in high schools. Exploratory, routine data from Medecins Sans Frontieres in Khayelitsha are presented, showing the popularity of alternatives to the government's 'Choice' brand. PMID- 29568583 TI - Routine cranial computed tomography before lumbar puncture in HIV-positive adults presenting with seizures at Mitchells Plain Hospital, Cape Town. AB - Background: Current international guidelines recommend that a cranial computed tomography (CT) be performed on all HIV-positive patients presenting with new onset seizures, before a lumbar puncture (LP) is performed. In the South African setting, however, this delay could be life threatening. The present study sought to measure the number of cranial CTs that contraindicate an LP and to predict which clinical signs and symptoms are likely to pose an increased risk from LP. Methods: The study was performed at a district level hospital in Western Cape Province. Data were collected retrospectively from October 2013 to October 2014. Associations between categorical variables were analysed using Pearson's chi squared test. Generalised linear regression was used to estimate prevalence ratios. Results: One hundred out of 132 patients were studied. Brain shift contraindicated an LP in 5% of patients. Patients with brain shift presented with decreased level of consciousness, focal signs, headache and neck stiffness. Twenty-five per cent of patients had a space-occupying lesion (SOL) (defined as a discrete lesion that has a measurable volume) or cerebral oedema. Multivariate analysis showed a CD4 count <50 (p = 0.033) to be a statistically significant predictor of patients with SOL and cerebral oedema. Univariate analysis showed focal signs (p = 0.0001), neck stiffness (p = 0.05), vomiting (p = 0.018) and a Glascow Coma Scale (GCS) < 15 (p = 0.002) to be predictors of SOL and cerebral oedema. Conclusion: HIV-positive patients with seizures have a high prevalence of SOL and cerebral oedema but the majority of them are safe for LP. Doctors can use clinical parameters to determine which patients can undergo immediate LP. PMID- 29568584 TI - Reconciling the science and policy divide: The reality of scaling up antiretroviral therapy in South Africa. AB - With the world's largest national treatment programme and over 340 000 incident cases annually, the response to HIV in South Africa is hotly contested and there is sometimes a dissonance between activism, science and policy. Too often, policy, whilst well intentioned, is informed only by epidemiological data. The state of the healthcare system and sociocultural factors drive and shape the epidemic and its response. By analysis of the financial, infrastructural, human resources for health, and governance landscape in South Africa, we assess the feasibility and associated costs of implementing a universal test and treat programme. We situate a universal test and treat strategy within the governance, fiscal, human resources for health, and infrastructural landscape in South Africa. We argue that the response to the epidemic must be forward thinking, progressive and make the most of the benefits from treatment as prevention. However, the logistics of implementing a universal test and treat strategy mean that this option is problematic in the short term. We recommend a health systems strengthening HIV treatment and prevention approach that includes scaling up treatment (for treatment and prevention) along with a range of other prevention strategies.

PMID- 29568588 TI - Reasons for failure of prevention of mother-to-child HIV transmission in a rural South African district hospital. AB - Further reduction of mother-to-child transmission (MTCT) of HIV requires improved understanding of the reasons for MTCT. We reviewed maternal and infant case notes for HIV-positive infants diagnosed by polymerase chain reaction at Bethesda Hospital. Nineteen cases were analysed. Median gestation at first antenatal consultation (ANC) was 22.5 (interquartile range [IQR] 19.25-24). Eleven (57.9%) mothers were HIV positive at first ANC, whilst eight tested negative and later positive (2 antepartum, 6 postpartum). Median maternal CD4 was 408 cells/MUL (IQR 318-531). Six (31.6%) received no antenatal antiretroviral therapy (ART) because they were diagnosed as HIV positive postpartum; 9 (47.3%) received antenatal ART and 3 (15.8%) were never initiated on ART. At 6 weeks postpartum, 5 infants (26.3%) were not on prophylactic nevirapine (NVP) because their mothers had not yet been diagnosed. Maternal seroconversion in pregnancy and breastfeeding, and possibly false-negative HIV tests, were important reasons for prevention of mother-to-child transmission (PMTCT) failure. PMID- 29568589 TI - Outcomes from the implementation of a counselling model supporting rapid antiretroviral treatment initiation in a primary healthcare clinic in Khayelitsha, South Africa. AB - Background: Lengthy antiretroviral treatment (ART) preparation contributes to high losses to care between communicating ART eligibility and initiating ART. To address this shortfall, Medecins Sans Frontieres implemented a revised approach to ART initiation counselling preparation (integrated for TB co-infected patients), shifting the emphasis from pre-initiation sessions to addressing common barriers to adherence and strengthening post-initiation support in a primary healthcare facility in Khayelitsha, South Africa. Methods: An observational cohort study was conducted using routinely collected data for all ART-eligible patients attending their first counselling session between 23 July 2012 and 30 April 2013 to assess losses to care prior to and post ART initiation. Viral load completion and suppression rates of those retained on ART were also calculated. Results: Overall, 449 patients enrolled in the study, of whom 3.6% did not return to the facility to initiate ART. Of those who were initiated, 96.7% were retained at their first ART refill visit and 85.9% were retained 6 months post ART initiation. Of those retained, 80.2% had a viral load taken within 6 months of initiating ART, with 95.4% achieving viral load suppression. Conclusions: Adapting counselling to enable rapid ART initiation is feasible and has the potential to reduce losses to care prior to ART initiation without increasing short-term losses thereafter or compromising patient adherence. PMID- 29568590 TI - A prospective study of demographic features and quality of life in HIV-positive women with cervical cancer treated at Tygerberg Hospital. AB - Background: Cervical cancer and human immunodeficiency virus (HIV) infection/acquired immune deficiency syndrome (AIDS) both have a high incidence in South Africa. Cervical cancer treatment of HIV-positive women poses challenges. Treatment-related changes in quality of life (QOL) of such women are important to future treatment protocols. Aim: To examine demographic data of HIV negative and HIV-positive women at diagnosis of cervical cancer and describe their changes in QOL as a result of treatment. Methods and materials: All newly diagnosed patients with cervical cancer at Tygerberg Hospital were approached to participate in the study. The European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) and the Cervix Cancer Module (QLQ-CX24) were used. General QOL was measured with the EORTC QLQ-C30 and cervical-specific QOL with the QLQ-CX24 questionnaire. The patients completed the questionnaire at diagnosis, on completion of treatment and at 3 months' follow up. Results: The study included a total of 221 women of whom 22% were HIV positive; the latter were younger and of higher educational level than the rest. Mean monthly income and stage distribution was similar between the two groups. HIV-positive patients underwent radiation therapy more commonly than chemoradiation. HIV-positive women showed statistically significantly higher loss to follow-up during the study. HIV-positive women experienced no improvement in insomnia, appetite loss, nausea, vomiting, diarrhoea, social role or any of the sexual domains. In contrast, HIV-negative women experienced statistically significant improvement in all sexual domains other than sexual/vaginal functioning. The QOL improvement of HIV-negative women was statistically significantly greater than their HIV-positive counterparts in the majority of QOL domains. Global health improved in both groups, with HIV-negative women experiencing greater improvement. HIV-positive women experienced an initial decline of peripheral neuropathy (PN) symptoms post treatment with a return to pretreatment values at 3 months' follow-up. The change in PN was statistically significant between the HIV-negative and HIV-positive women. Conclusion: Demographic differences exist between the HIV-negative and HIV-positive groups. The differential outcome in the QOL of HIV-positive and HIV-negative women treated for cervical cancer might be related to persistence of AIDS-related symptoms on completion of cervical cancer treatment. PMID- 29568591 TI - Recognising and managing increased HIV transmission risk in newborns. AB - Prevention of mother-to-child transmission (PMTCT) programmes have improved maternal health outcomes and reduced the incidence of paediatric HIV, resulting in improved child health and survival. Nevertheless, high-risk vertical exposures remain common and are responsible for a high proportion of transmissions. In the absence of antiretrovirals (ARVs), an 8- to 12-hour labour has approximately the same 15% risk of transmission as 18 months of mixed feeding. The intensity of transmission risk is highest during labour and delivery; however, the brevity of this intra-partum period lends itself to post-exposure interventions to reduce such risk. There is good evidence that infant post-exposure prophylaxis (PEP) reduces intra-partum transmission even in the absence of maternal prophylaxis. Recent reports suggest that infant combination ARV prophylaxis (cARP) is more efficient at reducing intra-partum transmission than a single agent in situations of minimal pre-labour prophylaxis. Guidelines from the developed world have incorporated infant cARP for increased-risk scenarios. In contrast, recent guidelines for low-resource settings have rightfully focused on reducing postnatal transmission to preserve the benefits of breastfeeding, but have largely ignored the potential of augmented infant PEP for reducing intra-partum transmissions. Minimal pre-labour prophylaxis, poor adherence in the month prior to delivery, elevated maternal viral load at delivery, spontaneous preterm labour with prolonged rupture of membranes and chorioamnionitis are simple clinical criteria that identify increased intra-partum transmission risk. In these increased-risk scenarios, transmission frequency may be halved by combining nevirapine and zidovudine as a form of boosted infant PEP. This strategy may be important to reduce intra-partum transmissions when PMTCT is suboptimal.

AB - The South African prevention of mother to child transmission programme has made excellent progress in reducing vertical HIV transmission, and paediatric antiretroviral therapy programmes have demonstrated good outcomes with increasing treatment initiation in younger children and infants. However, both in South Africa and across sub-Saharan African, lack of boosted peri-partum prophylaxis for high-risk vertical transmission, loss to follow-up, and failure to initiate HIV-infected infants on antiretroviral therapy (ART) before disease progression are key remaining gaps in neonatal HIV-related care. In this issue of the Southern African Journal of HIV Medicine, experts provide valuable recommendations for addressing these gaps. The present article highlights a number of areas where evidence is lacking to inform guidelines and programme development for optimal neonatal HIV-related care. PMID- 29568594 TI - Breastfeeding and the 2015 South African guidelines for prevention of mother-to child transmission of HIV. PMID- 29568595 TI - How ready are our health systems to implement prevention of mother to child transmission Option B+? AB - In January 2015, the South African National Department of Health released new consolidated guidelines for the prevention of mother to child transmission (PMTCT) of HIV, in line with the World Health Organization's (WHO) PMTCT Option B+. Implementing these guidelines should make it possible to eliminate mother to child transmission (MTCT) of HIV and improve long-term maternal and infant outcomes. The present article summarises the key recommendations of the 2015 guidelines and highlights current gaps that hinder optimal implementation; these include late antenatal booking (as a result of poor staff attitudes towards 'early bookers' and foreigners, unsuitable clinic hours, lack of transport to facilities, quota systems being applied to antenatal clients and clinic staff shortages); poor compliance with rapid HIV testing protocols; weak referral systems with inadequate follow-up; inadequate numbers of laboratory staff to handle HIV-related monitoring procedures and return of results to the correct facility; and inadequate supply chain management, leading to interrupted supplies of antiretroviral drugs. Additionally, recommendations are proposed on how to address these gaps. There is a need to evaluate the implementation of the 2015 guidelines and proactively communicate with ground-level implementers to identify operational bottlenecks, test solutions to these bottlenecks, and develop realistic implementation plans. PMID- 29568596 TI - HIV counselling and testing in secondary schools: What students want. AB - Background: HIV counselling and testing (HCT) is an essential element in the response to the HIV epidemic. There are still major research gaps about the best ways to provide HCT, especially to the youth, and school-based HCT is a model that has been suggested. To make HCT youth friendly and to enhance access to the service, the particular needs of the youth need to be addressed. Aim: To explore the expressed needs of students about school-based HCT service provision. Method: The study was conducted in 6 secondary schools in Cape Town where a mobile HCT service is provided by a non-governmental organisation. In each school, two mixed gender focus groups were held, one with grades 8 and 9 students and one with grades 10 and 11. A total of 91 students aged 13-21 were involved. The focus groups were conducted in the students' home language. All groups were audio recorded, transcribed verbatim and translated into English. Results: Content data analysis was done and the following themes emerged: (1) Where the students want HCT to be done, (2) How they want HCT to be done and (3) Who should do the counselling. Most students want HCT to be provided in schools on condition that their fears and expressed needs are taken into account. They raised concerns regarding privacy and confidentiality, and expressed the need to be given information regarding HCT before testing is done. They wanted staff providing the service to be experienced and trained to work with youth, and they wanted students who tested positive to be followed up and supported. Conclusion: To increase youth utilisation of the HCT service, their expressed needs should be taken into account when developing a model for school-based HCT. PMID- 29568597 TI - Guideline on the management of occupational and non-occupational exposure to the human immunodeficiency virus and recommendations for post-exposure prophylaxis: 2015 Update. AB - This guideline is an update of the post-exposure prophylaxis (PEP) guideline published by the Southern African HIV Clinicians Society in 2008. It updates the recommendations on the use of antiretroviral medications to prevent individuals who have been exposed to a potential HIV source, via either occupational or non occupational exposure, from becoming infected with HIV. No distinction is made between occupational or non-occupational exposure, and the guideline promotes the provision of PEP with three antiretroviral drugs if the exposure confers a significant transmission risk. The present guideline aligns with the principles of the World Health Organization PEP guidelines (2014), promoting simplification and adherence support to individuals receiving PEP. PMID- 29568598 TI - Southern African HIV Clinicians Society adult antiretroviral therapy guidelines: Update on when to initiate antiretroviral therapy. AB - The most recent version of the Southern African HIV Clinicians Society's adult antiretroviral therapy (ART) guidelines was published in December 2014. In the 27 August 2015 edition of the New England Journal of Medicine, two seminal randomised controlled trials that addressed the optimal timing of ART in HIV infected patients with high CD4 counts were published: Strategic timing of antiretroviral therapy (START) and TEMPRANO ANRS 12136 (Early antiretroviral treatment and/or early isoniazid prophylaxis against tuberculosis in HIV-infected adults). The findings of these two trials were consistent: there was significant individual clinical benefit from starting ART immediately in patients with CD4 counts higher than 500 cells/MUL rather than deferring until a certain lower CD4 threshold or clinical indication was met. The findings add to prior evidence showing that ART reduces the risk of onward HIV transmission. Therefore, early ART initiation has the public health benefits of potentially reducing both HIV incidence and morbidity. Given this new and important evidence, the Society took the decision to provide a specific update on the section of the adult ART guidelines relating to when ART should be initiated. PMID- 29568599 TI - Hepatitis B co-infection in HIV-infected patients receiving antiretroviral therapy at the TC Newman Anti Retroviral Treatment Clinic in Paarl, Western Cape. AB - Background: Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) co infection in South Africa is estimated to be between 5% and 23%; however, only limited evidence is available. Co-infection increases the risk of chronification of HBV, liver cirrhosis and death. Objective: To assess the HBV and/or HIV co infection rate amongst the adult antiretroviral treatment cohort at the TC Newman ART Clinic in Paarl, Western Cape. Methods: In a retrospective, cross-sectional study, the routine hepatitis B surface antigen screening results for all adult HIV patients who were started on antiretroviral treatment over a period of 19 months were collected and analysed for gender, CD4 count and age. Results: Amongst the 498 participants (60% female participants), the Hepatitis B surface Antigen positivity rate was 7.6%. Male gender, age between 50 and 59 years and a low CD4 count were correlated with higher rates. Conclusion: Useful insight could be obtained by analysing routine data. The prevalence of almost 8% confirms the need for testing of HIV-positive patients for hepatitis B. PMID- 29568600 TI - Feeding practices and nutritional status of HIV-exposed and HIV-unexposed infants in the Western Cape. AB - Background: Optimal infant- and young child-feeding practices are crucial for nutritional status, growth, development, health and, ultimately, survival. Human breast milk is optimal nutrition for all infants. Complementary food introduced at the correct age is part of optimal feeding practices. In South Africa, widespread access to antiretrovirals and a programme to prevent mother-to-child transmission of HIV have reduced HIV infection in infants and increased the number of HIV-exposed uninfected (HEU) infants. However, little is known about the feeding practices and nutritional status of HEU and HIV-unexposed (HU) infants. Objective: To assess the feeding practices and nutritional status of HIV exposed and HIV-unexposed (HU) infants in the Western Cape. Design: Prospective substudy on feeding practices nested in a pilot study investigating the innate immune abnormalities in HEU infants compared to HU infants. The main study commenced at week 2 of life with the nutrition component added from 6 months. Information on children's dietary intake was obtained at each visit from the caregiver, mainly the mother. Head circumference, weight and length were recorded at each visit. Data were obtained from 6-, 12- and 18-month visits. World Health Organization feeding practice indicators and nutrition indicators were utilised. Setting: Tygerberg Academic Hospital, Western Cape. Mothers were recruited from the postnatal wards. Subjects: Forty-seven mother-infant pairs, 25 HEU and 22 HU infants, participated in this nutritional substudy. Eight (17%) infants, one HU and seven HEU, were lost to follow-up over the next 12 months. The HEU children were mainly Xhosa (76%) and HU were mainly mixed race (77%). Results: The participants were from poor socio-economic backgrounds. In both groups, adherence to breastfeeding recommendations was low with suboptimal dietary diversity. We noted a high rate of sugar- and salt-containing snacks given from a young age. The HU group had poorer anthropometric and nutritional indicators not explained by nutritional factors alone. However, alcohol and tobacco use was much higher amongst the HU mothers. Conclusion: Adherence to breastfeeding recommendations was low. Ethnicity and cultural milieu may have influenced feeding choices and growth. Further research is needed to understand possible reasons for the poorer nutritional and anthropometric indicators in the HU group. PMID- 29568601 TI - Treatment outcomes in a rural HIV clinic in South Africa: Implications for health care. AB - Objective: To assess the treatment outcomes of an HIV clinic in rural Limpopo province, South Africa. Methods: A retrospective cohort study involving medical records review of HIV-positive patients initiated on antiretroviral treatment (ART) was conducted from December 2007 to November 2008 at Letaba Hospital. Data on socio-demographic characteristics, CD4 counts, viral loads (VLs), opportunistic infections, adverse effects of treatment, hospital admissions, and patient retention at 6, 12, 24, and 36 months on ART were collected. Analysis included descriptive statistics, chi-square and t-tests. Results: Of 124 patient records sampled, the majority of patients were female (69%), single (49%), unemployed (56%), living at least 10 km from the hospital (52.4%), and were on treatment at 36 months (69%). Approximately 84% of patients achieved viral suppression (VLs < 400 copies/mL) by 6 months of ART and the mean CD4 count increased from 128 at baseline to 470 cells/mm3 at 24 months. There was a mean weight gain of 5.9 kg over the 36 months and the proportion of patients with opportunistic infections decreased from 54.8% (n = 68) at baseline to 15.3% (n = 19) at 36 months. Although the largest improvements in CD4, VLs, and weights were recorded in the first 6 months of ART, viral rebound became evident thereafter. Of all variables, only age < 50 years and being pregnant were significantly associated with higher VLs (p = 0.03). Conclusion: Good treatment outcomes are achievable in a rural South African ART clinic. However, early viral rebound and higher VLs in pregnancy highlight the need for enhanced treatment adherence support, especially for pregnant women to reduce the risk of mother to child transmission. PMID- 29568602 TI - HIV and/or AIDS awareness among adolescents in a South African at-risk rural community. AB - Background: The devastating effects of HIV and/or AIDS are widely documented. Despite ongoing efforts to address the challenges associated with the pandemic, the impact on children orphaned because of the disease, as well as on adolescents, remains problematic. More specifically, orphaned adolescents living in poverty are particularly vulnerable and are often exposed to, for example, emotional and physical abuse and transactional sexual exploitation. Against this background, the importance of informed awareness among adolescents is continually emphasised, yet the outcomes of awareness campaigns require ongoing research. Objectives: The main objective of this study was to explore HIV and/or AIDS awareness among adolescents living in a rural community in South Africa, in the Chris Hani District of the Eastern Cape Province. Sixteen adolescents (aged 12 24) who had lost one or both of their parents because of HIV and/or AIDS-related reasons were purposefully selected to participate in the study. Method: For this qualitative investigation, we implemented a descriptive case study design. Semi structured individual interviews, observation and field notes were used to collect and document data, and inductive thematic analysis was completed using the software programme Atlas.ti 7. Results: The three themes that were identified relate to HIV and/or AIDS awareness, disclosure of parents' HIV and/or AIDS status and experiences of adolescents surrounding the death of their parents. Adolescents of the community viewed HIV and/or AIDS as an infectious disease that can lead to death; however, this can be prevented by avoiding at-risk sexual behaviour. Schools and family members were the main sources of information regarding HIV and/or AIDS to the participants. Even though parents tended not to disclose their HIV and/or AIDS status, adolescents became aware of their parents' status when reading about this on their parents' medical report cards or when being told about the status by others following the death of their parents. For adolescents, their parents' deaths were associated with the parents being chronically ill or showing visible signs of deterioration such as weight loss. Conclusion: The study concludes that even though current campaigns and informative interventions have seemingly succeeded in ensuring HIV and/or AIDS awareness among adolescents - also those in remote areas - continued educational campaigns are important. Such initiatives may prove to be beneficial by focusing on ways that parents can discuss HIV and/or AIDS-related issues with their children and disclose an HIV-positive status. PMID- 29568603 TI - The prevalence of HIV in the sudden, unexplained and unexpected death population at the Pretoria Medico-Legal Laboratory. AB - Purpose: To determine the prevalence of HIV in the sudden, unexplained and unexpected (SUU) death population admitted to the Pretoria Medico-Legal Laboratory. Methods: This study was conducted at the Pretoria Medico-Legal Laboratory. Blood samples were obtained from decedents who died suddenly and/or unexpectedly, during autopsy, by a forensic pathologist. Sample collection continued until 100 valid samples were analysed for HIV antibodies. The data collected included demographic details and case-related information. Results and Conclusion: SUU deaths accounted for 14% of all cases admitted to the Pretoria Medico-Legal Laboratory. The HIV prevalence in the SUU deaths was 43%, which is 17% higher than the general mortuary population in Pretoria (p = 0.0045). The majority of these deaths were due to respiratory disease processes, with 12 cases having HIV/TB co-infection. PMID- 29568604 TI - The profile and frequency of known risk factors or comorbidities for deep vein thrombosis in an urban district hospital in KwaZulu-Natal. AB - Background: Although deep vein thrombosis (DVT) is a preventable disease, it increases the morbidity and mortality in hospitalised, patients, resulting in considerable economic health impact. The identification and primary prevention of risk factors using risk assessment and stratification with subsequent anti thrombotic prophylaxis in moderate- to severe-risk categories is the most rational means of reducing morbidity and mortality. Aim and setting: The aim of the study was to describe the profile and frequency of known risk factors or comorbidities of hospitalised medical patients with ultrasound-diagnosed DVT in an urban district hospital in KwaZulu-Natal. Methods: A retrospective review of clinical notes of all medical patients (age >= 13 years) admitted to the hospital with ultrasound-diagnosed DVT between July and December 2013. Results: The median age was 40 years (interquartile range 32-60 years) and female preponderance was 72.84%. HIV and tuberculosis emerged as the prevalent risk factors, accounting for 51.85% and 35.80%, respectively. Other risk factors observed were recent hospitalisation (34.57%), smoking (25.93%), previous DVT (19.75%) and congestive cardiac failure (18.52%). Conclusion: DVT in our study occurred predominantly in young female patients unlike previous studies where patients were generally older. Furthermore, HIV and tuberculosis were the two most common known risk factors or comorbidities observed. Clinicians should have a heightened awareness of venous thromboembolism in patients with either condition or where both conditions occur together and appropriate thromboprophylaxis should be administered. PMID- 29568605 TI - PIMATM point-of-care testing for CD4 counts in predicting antiretroviral initiation in HIV-infected individuals in KwaZulu-Natal, Durban, South Africa. AB - Introduction: Limited information is available on the usefulness of the PIMATM analyser in predicting antiretroviral treatment eligibility and outcome in a primary healthcare clinic setting in disadvantaged communities in KwaZulu-Natal, South Africa. Materials and methods: The study was conducted under the eThekwini Health Unit, Durban, KwaZulu-Natal. Comparison of the enumeration of CD4+ T-cells in 268 patients using the PIMATM analyser and the predicate National Health Laboratory Services (NHLS) was undertaken during January to July 2013. Bland Altman analysis to calculate bias and limits of agreement, precision and levels of clinical misclassification at various CD4+ T-cell count thresholds was performed. Results: There was high precision of the PIMATM control bead cartridges with low and normal CD4+ T-cell counts using three different PIMATM analysers (%CV < 5). Under World Health Organization (WHO) guidelines (<= 500 cells/mm3), the sensitivity of the PIMATM analyser was 94%, specificity 78% and positive predictive value (PPV) 95%. There were 24 (9%) misclassifications, of which 13 were false-negative in whom the mean bias was 149 CD4+ T-cells/mm3. Most (87%) patients returned for their CD4 test result but only 67% (110/164) of those eligible (<= 350 cells/mm3) were initiated on antiretroviral therapy (ART) with a time to treatment of 49 days (interquartile range [IQR], 42-64 days). Conclusion: There was adequate agreement between PIMATM analyser and predicate NHLS CD4+ T cell count enumeration (<= 500 cells/mm3) in adult HIV-positive individuals. The high PPV, sensitivity and acceptable specificity of the PIMATM analyser technology lend it as a reliable tool in predicting eligibility and rapid linkage to care in ART programmes. PMID- 29568607 TI - What is the role of CD4 count in a large public health antiretroviral programme? PMID- 29568606 TI - Immune activation is associated with decreased thymic function in asymptomatic, untreated HIV-infected individuals. AB - Background: Reduced thymic function causes poor immunological reconstitution in human immunodeficiency virus (HIV)-positive patients on combined antiretroviral therapy (cART). The association between immune activation and thymic function in asymptomatic HIV-positive treatment-naive individuals has thus far not been investigated. Aims and objectives: To optimise a five-colour flow cytometric assay for measurement of thymic function by measuring recent thymic emigrants (RTEs) in treatment-naive HIV-infected patients and healthy controls and correlate results with levels of immune activation, CD4 counts and viral load. Methods: Blood obtained from 53 consenting HIV-positive individuals and 32 controls recruited from HIV prevention and testing clinic in Cape Town, South Africa. RTEs were measured (CD3+/CD4+/CD45RA+/CD31+/CD62L+) and levels were correlated with CD4 counts of HIV-infected individuals, log viral load and levels of immune activation (CD8+/CD38+ T-cells). Results: HIV-infected individuals had reduced frequencies of RTEs when compared to controls (p = 0.0035). Levels of immune activation were inversely correlated with thymic function (p = 0.0403), and the thymic function in HIV-infected individuals showed no significant correlation with CD4 counts (p = 0.31559) and viral load (p = 0.20628). Conclusions: There was impaired thymic function in HIV-infected individuals, which was associated with increased levels of immune activation. The thymic dysfunction was not associated with CD4 counts and viral load. Immune activation may result in inflammatory damage to the thymus and subsequent thymic dysfunction, and CD4 counts and viral load may not necessarily reflect thymic dysfunction in HIV. PMID- 29568608 TI - Compliance to HIV treatment monitoring guidelines can reduce laboratory costs. AB - Background: Panel tests are a predetermined group of tests commonly requested together to provide a comprehensive and conclusive diagnosis, for example, liver function test (LFT). South African HIV antiretroviral treatment (ART) guidelines recommend individual tests for toxicity monitoring over panel tests. In 2008, the National Health Laboratory Services (NHLS) request form was redesigned to list individual tests instead of panel tests and removed the 'other tests' box option to facilitate efficient ART laboratory monitoring. Objectives: This study aimed to demonstrate changes in laboratory expenditure, for individual and panel tests, for ART toxicity monitoring. Method: NHLS Corporate Data Warehouse (CDW) data were extracted for HIV conditional grant accounts to assess ART toxicity monitoring laboratory expenditure between 2010/2011 and 2014/2015. Data were classified based on the tests requested, as either panel (LFT or urea and electrolytes) or individual (alanine transaminase or creatinine) tests. Results: Expenditure on panel tests reduced from R340 million in 2010/2011 to R140m by 2014/2015 (reduction of R204m) and individual test expenditure increased from R34m to R76m (twofold increase). A significant reduction in LFT panel expenditure was noted, reducing from R322m in 2010/2011 to R130m in 2014/2015 (60% reduction). Conclusion: Changes in toxicity monitoring guidelines and the re engineering of the NHLS request form successfully reduced expenditure on panel tests relative to individual tests. The introduction of order entry systems could further reduce unnecessary laboratory expenditure. PMID- 29568609 TI - Computational models as predictors of HIV treatment outcomes for the Phidisa cohort in South Africa. AB - Background: Selecting the optimal combination of HIV drugs for an individual in resource-limited settings is challenging because of the limited availability of drugs and genotyping. Objective: The evaluation as a potential treatment support tool of computational models that predict response to therapy without a genotype, using cases from the Phidisa cohort in South Africa. Methods: Cases from Phidisa of treatment change following failure were identified that had the following data available: baseline CD4 count and viral load, details of failing and previous antiretroviral drugs, drugs in new regimen and time to follow-up. The HIV Resistance Response Database Initiative's (RDI's) models used these data to predict the probability of a viral load < 50 copies/mL at follow-up. The models were also used to identify effective alternative combinations of three locally available drugs. Results: The models achieved accuracy (area under the receiver operator characteristic curve) of 0.72 when predicting response to therapy, which is less accurate than for an independent global test set (0.80) but at least comparable to that of genotyping with rules-based interpretation. The models were able to identify alternative locally available three-drug regimens that were predicted to be effective in 69% of all cases and 62% of those whose new treatment failed in the clinic. Conclusion: The predictive accuracy of the models for these South African patients together with the results of previous studies suggest that the RDI's models have the potential to optimise treatment selection and reduce virological failure in different patient populations, without the use of a genotype. PMID- 29568610 TI - Recommendations for the management of indeterminate HIV PCR results within South Africa's early infant diagnosis programme. AB - Indeterminate HIV PCR results represent missed diagnostic opportunities within South Africa's early infant diagnosis programme. These results not only delay diagnosis and appropriate management but are also a source of confusion and apprehension amongst clinicians and caregivers. We describe the extent of indeterminate HIV PCR results within South Africa's early infant diagnosis programme and provide recommendations for the management of these cases, both in terms of laboratory practice and the clinical care of the infants. PMID- 29568611 TI - Incidence of neuropsychiatric side effects of efavirenz in HIV-positive treatment naive patients in public-sector clinics in the Eastern Cape. AB - Background: It is acknowledged that almost half of patients initiated on efavirenz will experience at least one neuropsychiatric side effect. Objectives: The aim was to determine the incidence and severity of neuropsychiatric side effects associated with efavirenz use in five public-sector primary healthcare clinics in the Eastern Cape. Method: The study was a prospective drug utilisation study. A total of 126 medical records were reviewed to obtain the required information. After baseline assessment, follow-up reviews were conducted at 4 weeks, 12 weeks and 24 weeks from 2014 to 2015. Results: The participant group was 74.60% female (n = 94), and the average age was 37.57+/-10.60 years. There were no neuropsychiatric side effects recorded for any patient. After the full follow-up period, there were a total of 49 non-adherent patients and one patient had demised. A non-adherent patient was defined as a patient who did not return to the clinic for follow-up assessment and medication refills 30 days or more after the appointed date. Some patients (n = 11) had sent a third party to the clinic to collect their antiretroviral therapy (ART). The clinic pharmacy would at times dispense a two-month supply of medication resulting in the patient presenting only every two months. Conclusion: Further pharmacovigilance studies need to be conducted to determine the true incidence of these side effects. Healthcare staff must be encouraged to keep complete records to ensure meaningful patient assessments. Patients being initiated on ART need to personally attend the clinic monthly for at least the first 6 months of treatment. Clinic staff should receive regular training concerning ART, including changes made to guidelines as well as reminders of side effects experienced. PMID- 29568612 TI - The end of the line? A case of drug resistance to third-line antiretroviral therapy. AB - HIV drug resistance has been described in all antiretroviral drug classes and threatens the long-term success of HIV treatment. Here, we describe the first reported case of acquired resistance to the integrase strand transfer inhibitors in South Africa. This case illustrates the dilemma of treatment in the context of inadequate adherence and poor psychosocial support and highlights the potential risk of transmission of multidrug-resistant virus. PMID- 29568613 TI - Southern African guidelines on the safe use of pre-exposure prophylaxis in persons at risk of acquiring HIV-1 infection. AB - The Southern African HIV Clinicians Society published its first set of oral pre exposure prophylaxis (PrEP) guidelines in June 2012 for men who have sex with men (MSM) who are at risk of HIV infection. With the flurry of data that has been generated in PrEP clinical research since the first guideline, it became evident that there was a need to revise and expand the PrEP guidelines with new evidence of safety and efficacy of PrEP in several populations, including MSM, transgender persons, heterosexual men and women, HIV-serodiscordant couples and people who inject drugs. This need is particularly relevant following the World Health Organization (WHO) Consolidated Treatment Guidelines released in September 2015. These guidelines advise that PrEP is a highly effective, safe, biomedical option for HIV prevention that can be incorporated with other combination prevention strategies in Southern Africa, given the high prevalence of HIV in the region. PrEP should be tailored to populations at highest risk of HIV acquisition, whilst further data from studies in the region accrue to guide optimal deployment to realise the greatest impact regionally. PrEP may be used intermittently during periods of perceived HIV acquisition risk, rather than continually and lifelong, as is the case with antiretroviral treatment. Recognition and accurate measurement of potential risk in individuals and populations also warrants discussion, but are not extensively covered in these guidelines. PMID- 29568614 TI - Associations between plasma tenofovir concentration and renal function markers in HIV-infected women. AB - Background: Tenofovir disoproxil fumarate (TDF) has been associated with kidney tubular dysfunction and reduced renal function. Limited studies were performed in Europe and Asia that related plasma tenofovir (TFV) concentration with renal function; no such studies to date have been performed on Africans. Objective: To investigate the correlation between plasma tenofovir (TFV) concentration and certain renal function markers in HIV-infected women on TDF antiretroviral therapy (ART). These markers were also compared to a HIV-uninfected control group. Methods: HIV-infected women (n = 30) on TDF-based ART were matched with 30 controls for age and body mass index. Renal markers analysed were estimated glomerular filtration rate (eGFR), creatinine clearance (CrCl), serum creatinine, albuminuria, glucosuria, serum urea, serum uric acid, urine sodium and maximum tubular reabsorption of phosphate. Baseline eGFR and CrCl data were obtained retrospectively for the HIV-infected women. Plasma TFV was assayed using a validated HPLC-MS/MS method. Stepwise regression, Mann-Whitney test, unpaired and paired t-tests were applied in the statistical analyses. Results: TFV concentration was independently associated with albuminuria (adjusted r2 = 0.339; p = 0.001) in HIV-infected women. In the adjusted (weight) analysis, eGFR (p = 0.038), CrCl (p = 0.032) and albuminuria (p = 0.048) were significantly higher in HIV-infected compared to the uninfected women, but eGFR was abnormally high in HIV-infected women. Both eGFR (p < 0.001) and CrCl (p = 0.008) increased from baseline to follow-up in HIV-infected women. Conclusion: Plasma TFV concentration was associated with increased albuminuria in HIV-infected women in this sub study. Both eGFR and CrCl were increased in HIV-infected women from baseline. These findings should be confirmed in larger studies, and hyperfiltration in HIV infected women warrants further investigation. PMID- 29568615 TI - When will sub-Saharan Africa adopt HIV treatment for all? AB - Background: The World Health Organization (WHO) HIV treatment guidelines have been used by various countries to revise their national guidelines. Our study discusses the national policy response to the HIV epidemic in sub-Saharan Africa and quantifies delays in adopting the WHO guidelines published in 2009, 2013 and 2015. Methods: From the Internet, health authorities and experts, and community members, we collected 59 published HIV guidelines from 33 countries in the sub Saharan African region, and abstracted dates of publication and antiretroviral therapy (ART) eligibility criteria. For these 33 countries, representing 97% regional HIV burden in 2015, the number of months taken to adopt the WHO 2009, 2013 and/or 2015 guidelines were calculated to determine the average delay in months needed to publish revised national guidelines. Findings: Of the 33 countries, 3 (6% regional burden) are recommending ART according to the WHO 2015 guidelines (irrespective of CD4 count); 19 (65% regional burden) are recommending ART according to the WHO 2013 guidelines (CD4 count <= 500 cells/mm3); and 11 (26% regional burden) according to the WHO 2009 guidelines (CD4 count <= 350 cells/mm3). The average time lag to WHO 2009 guidelines adoption in 33 countries was 24 (range 3-56) months. The 22 that have adopted the WHO 2013 guidelines took an average of 10 (range 0-36) months, whilst the three countries that adopted the WHO 2015 guidelines took an average of 8 (range 7-9) months. Conclusion: There is an urgent need to shorten the time lag in adopting and implementing the new WHO guidelines recommending 'treatment for all' to achieve the 90-90-90 targets. PMID- 29568616 TI - Survival after Pneumocystis jirovecii pneumonia requiring ventilation: A case report. AB - Pneumocystis pneumonia (PCP) in patients with the human immunodeficiency virus (HIV) is associated with a high mortality rate, which increases substantially with the need for mechanical ventilation. Local experience of patients with PCP admitted to the intensive care unit has revealed mortality rates close to 100%. We present a case of a 39-year-old HIV-infected man diagnosed with PCP who was successfully weaned from mechanical ventilation after presenting with respiratory distress and severe hypoxaemia. A short review of the literature will also be presented. PMID- 29568617 TI - Health-related quality of life of antiretroviral treatment defaulters in Botswana. AB - Background: Antiretroviral therapy (ART) improves patients' health-related quality of life (HRQoL). Defaulting from ART has detrimental consequences, including the development of viral resistance, treatment failure and increased risks of disease progression. Little is known about the quality of life of ART defaulters and reasons for discontinuing their ART. Objectives: This study sought to measure the HRQoL of ART patients in Botswana who were on ART for up to 5 years but had discontinued treatment for at least 3 months, and to identify factors associated with ART defaulting. Method: We conducted a cross-sectional study with 104 eligible respondents in four ART clinics in south eastern Botswana. We assessed respondents' HRQoL using the World Health Organization Quality of Life Questionnaire for HIV short form. Clinical information was obtained from respondents' medical records. Data were analysed using SAS version 9.2. Results: Reasons for discontinuing ART were inaccessible clinics (22.4%), feeling better (21.4%), running out of pills (11.2%), depression (8.2%), lack of care and/or support (8.2%), failure to understand instructions (7.7%), medications' side effects (6.1%) and alcohol abuse (3.1%). In multivariate analyses, respondents aged 36-45 years had a 0.03 lower independence HRQoL score compared to those aged 35 and younger (beta = -0.03; 95% confidence interval: 1.72, -1.66). Despite defaulting from their ART, respondents' calculated HRQoL scores were moderate. Conclusion: This study highlights the need to enhance ART adherence in order to improve the HRQoL of people living with HIV and/or AIDS. PMID- 29568618 TI - Barriers to adherence to antiretroviral treatment in a regional hospital in Vredenburg, Western Cape, South Africa. AB - Background: South Africa currently runs the largest public antiretroviral treatment (ART) programme in the world, with over 80% of people living with HIV and/or AIDS on ART. However, in order to appreciate the benefits of using ART, patients are subject to uncompromising and long-term commitments of taking at least 95% of their treatment as prescribed. Evidence shows that this level of adherence is seldom achieved because of a multilevel and sometimes interwoven myriad of factors. Objective: We described the challenges faced by patients on ART in Vredenburg with regard to ART adherence. Methods: A descriptive qualitative research design was used. Eighteen non-adhering patients on ART in the Vredenburg regional hospital were purposefully selected. Using a semi structured interview guide, we conducted in-depth interviews with the study participants in their mother tongue (Afrikaans). The interviews were audio-taped, transcribed verbatim and translated into English. The data were analysed manually using the thematic content analysis method. Results: Stigma, disclosure, unemployment, lack of transport, insufficient feeding, disability grants and alternative forms of therapy were identified as major barriers to adherence, whereas inadequate follow-ups and lack of patient confidentiality came under major criticisms from the patients. Conclusion: Interventions to address poverty, stigma, discrimination and disclosure should be integrated with group-based ART adherence models in Vredenburg while further quantitative investigations should be carried out to quantify the extent to which these factors impede adherence in the community. PMID- 29568619 TI - Knowledge and practice of condom use as well as perceived barriers among street adolescents in Cameroon. AB - Introduction: Street children in Cameroon are adolescents, vulnerable to sexually transmitted infections (STIs) and HIV and/or AIDS. The level of knowledge and practice of condom use among this population is unknown. Objective of the study: To assess the knowledge, practice and barriers to condom use in Cameroon. Materials and methods: The study was an analytical cross-sectional survey conducted in 2015. Questionnaires were administered to street children in a quiet location. Recruitment was made using the snowball technique with the help of peers. Results: More than 90% of participants knew of condoms, but only about 6% reported to have used a condom during their last sexual encounter. Most of the participants did not know that condoms could prevent HIV; only a few (15.5%) knew about this. Conclusion: Street adolescents in Cameroon seem to know about condoms, but have insufficient information on the importance of their regular use. The main barriers for the low practice of condom use reported by this population were the following: condoms hinder sexual pleasure; are costly; and it is embarrassing to buy, use or propose to use a condom. PMID- 29568620 TI - Reported health, lifestyle and clinical manifestations associated with HIV status in people from rural and urban communities in the Free State Province, South Africa. AB - Background: HIV infection impacts heavily on the infected individual's overall health status. Aim: To determine significant health, lifestyle (smoking and alcohol use) and independent clinical manifestations associated with HIV status in rural and urban communities. Methods: Adults aged between 25 and 64 years completed a questionnaire in a structured interview with each participant. Blood specimens were analysed in an accredited laboratory using standard techniques and controls. Anthropometric measurements were determined using standardised methods. Results: Of the 567 rural participants, 97 (17.1%) were HIV-infected, and 172 (40.6%) of the 424 urban participants. More than half of HIV-infected rural participants used alcohol and more than 40% smoked. Median body mass index (BMI) of HIV-infected participants was lower than that of uninfected participants. Significantly more HIV-infected participants reported experiencing cough (rural), skin rash (urban), diarrhoea (rural and urban), vomiting (rural), loss of appetite (urban) and involuntary weight loss (rural). Significantly more HIV uninfected participants reported diabetes mellitus (urban) and high blood pressure (rural and urban). In rural areas, HIV infection was positively associated with losing weight involuntarily (odds ratio 1.86), ever being diagnosed with tuberculosis (TB) (odds ratio 2.50) and being on TB treatment (odds ratio 3.29). In the urban sample, HIV infection was positively associated with having diarrhoea (odds ratio 2.04) and ever being diagnosed with TB (odds ratio 2.49). Conclusion: Involuntary weight loss and diarrhoea were most likely to predict the presence of HIV. In addition, present or past diagnosis of TB increased the odds of being HIV-infected. Information related to diarrhoea, weight loss and TB is easy to obtain from patients and should prompt healthcare workers to screen for HIV. PMID- 29568621 TI - Attitude shifts and knowledge gains: Evaluating men who have sex with men sensitisation training for healthcare workers in the Western Cape, South Africa. AB - Background: Men who have sex with men (MSM) in South Africa experience discrimination from healthcare workers (HCWs), impeding health service access. Objectives: To evaluate the outcomes of an MSM sensitisation training programme for HCWs implemented in the Western Cape province (South Africa). Methods: A training programme was developed to equip HCWs with the knowledge, awareness and skills required to provide non-discriminatory, non-judgemental and appropriate services to MSM. Overall, 592 HCWs were trained between February 2010 and May 2012. Trainees completed self-administered pre- and post-training questionnaires assessing changes in knowledge. Two-sample t-tests for proportion were used to assess changes in specific answers and the Wilcoxon rank-sum test for overall knowledge scores. Qualitative data came from anonymous post-training evaluation forms completed by all trainees, in combination with four focus group discussions (n = 28) conducted six months after their training. Results: Fourteen per cent of trainees had received previous training to counsel clients around penile-anal intercourse, and 16% had previously received training around sexual health issues affecting MSM. There was a statistically significant improvement in overall knowledge scores (80% - 87%, p < 0.0001), specifically around penile-anal intercourse, substance use and depression after the training. Reductions in negative attitudes towards MSM and increased ability for HCWs to provide non discriminatory care were reported as a result of the training. Conclusion: MSM sensitisation training for HCWs is an effective intervention to increase awareness on issues pertaining to MSM and how to engage around them, reduce discriminatory attitudes and enable the provision of non-judgemental and appropriate services by HCWs. PMID- 29568622 TI - Photosensitive disorders in HIV. AB - Photosensitive disorders are common, affecting up to 5% of HIV-positive patients. HIV itself induces photosensitivity but photoaggravated drug reactions, porphyria cutanea tarda and nutritional disorders such as pellagra are also more common in patients with HIV. In South Africa, actinic lichenoid leukomelanoderma of HIV is a unique photosensitive disorder which is associated with advanced HIV. It is important to be able to recognise these conditions and withdraw photosensitising medications wherever possible. PMID- 29568623 TI - Patients' recommendations for a patient-centred public antiretroviral therapy programme in eThekwini, KwaZulu-Natal. AB - Background: The South African antiretroviral therapy (ART) programme, which is in its second decade of existence, includes many successes and challenges. This study provides patients' recommendations to address the challenges they currently experience at four antiretroviral (ARV) clinics based in urban public hospitals in order to provide a patient-centred service. Objectives: To use patients' recommendations to develop intervention strategies to improve patients' experiences of the public ART programme. Method: A three-stage, sequential, mixed method study was implemented. Stage 1 recruited five patients from the four sites to formulate and test a structured questionnaire prior to data collection. Stage 2 recruited a stratified random sample of 400 patients (100 from each hospital) to complete the administered structured questionnaire. Stage 3 purposively selected 12 patients (three from each of the four sites) to participate in in depth audio-recorded interviews using an interview schedule. Results: The 412 patients prioritised six recommendations, which are as follows: waiting areas should be enclosed to protect patients from the elements (rain, sun, lightening, wind and cold); patients should not have to return their files to the main hospital or ARV clinic themselves; stable patients should collect their ARV drugs every three months; pharmacy opening and closing times should be revised to suit patients' needs; HIV-positive patient representatives should be elected at each ARV clinic to address patients' concerns and/or challenges to ensure that the programme could be more patient-centred and ARV clinic operating times should be extended to open later during weekdays and over weekends. Conclusion: Patients living with HIV have a valuable contribution to make in assessing service delivery and making recommendations to create a patient-centred healthcare environment, which will feasibly increase their adherence to ART. PMID- 29568624 TI - HIV and the histopathologist. AB - The practicing histopathologist is often a forgotten link in the management of HIV patients. This article aims to highlight the unique challenges faced by anatomical pathologists as well as focusing on the valuable contribution they can make to ensure prompt and accurate diagnoses that will ultimately benefit the patient. PMID- 29568625 TI - The neuromyelitis optica presentation and the aquaporin-4 antibody in HIV seropositive and seronegative patients in KwaZulu-Natal, South Africa. AB - Background: The association of the anti-aquaporin-4 (AQP-4) water channel antibody with neuromyelitis optica (NMO) syndrome has been described from various parts of the world. There has been no large study describing this association from southern Africa, an HIV endemic area. HIV patients often present with visual disturbance or features of a myelopathy but seldom both either simultaneously or consecutively. We report our experience of NMO in the era of AQP-4 testing in HIV positive and HIV-negative patients seen in KwaZulu-Natal, South Africa. Methods: A retrospective chart review was undertaken of NMO cases seen from January 2005 to April 2016 in two neurology units serving a population of 7.1 million adults. The clinical, radiological and relevant laboratory data were extracted from the files and analysed. Results: There were 12 HIV-positive patients (mean age 33 years), 9 (75%) were women and all 12 were black patients. Of the 17 HIV-negative patients (mean age 32 years), 15 (88%) were women and 10 (59%) were black people. The clinical features in the two groups ranged from isolated optic neuritis, isolated longitudinally extensive myelitis or combinations. Recurrent attacks were noted in six HIV-positive patients and six HIV-negative patients. The AQP-4 antibody was positive in 4/10 (40%) HIV-positive patients and 11/13 (85%) HIV negative patients. The radiological changes ranged from longitudinal hyperintense spinal cord lesions and long segment enhancing lesions of the optic nerves. Three patients, all HIV-positive, had tumefactive lesions with incomplete ring enhancement. Conclusion: This study confirms the presence of AQP-4-positive NMO in southern Africa in both HIV-positive and HIV-negative patients. The simultaneous or consecutive occurrence of optic neuritis and myelitis in an HIV positive patient should alert the clinician to test for the AQP-4 antibody. It is important to recognise this clinical syndrome as specific therapy is available. We further postulate that HIV itself may act as a trigger for an autoimmune process. PMID- 29568626 TI - Prevention of mother-to-child transmission of HIV guidelines: Nurses' views at four primary healthcare facilities in the Limpopo Province. AB - Background: When new guidelines for existing programmes are introduced, it is often the clinicians tasked with the execution of the guidelines who bear the brunt of the changes. Frequently their opinions are not sought. In this study, the researcher interviewed registered nurses working in the field of the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) to gain an understanding of their perspectives on the changes introduced to the guidelines. The guideline changes in 2014 were to move from the World Health Organization (WHO) Option B to Option B + which prescribes lifelong antiretroviral therapy (ART) for all HIV-positive pregnant women regardless of CD4 cell count. Objective: To determine what the registered nurses' perspectives are on the PMTCT programme as implemented at four PHC facilities in the Limpopo Province. Method: For this qualitative investigation, a descriptive research design was implemented. The data were collected during semi-structured interviews with nurses from four primary healthcare facilities in the Limpopo Province of South Africa. Data were analysed using thematic analysis. Results: Challenges preventing effective implementation (e.g. increased workloads, viz. staff shortages; poor planning of training; equipment and medication shortages and long lead times; poor patient education) were identified. Conclusion: In spite of the successes of the PMTCT programme, considerable challenges still prevail; lack of patient education, poor facilities management and staff shortages could potentially influence the implementation of the PMTCT guidelines negatively. PMID- 29568627 TI - Non-disclosure of HIV-positive status to a partner and mother-to-child transmission of HIV: Evidence from a case-control study conducted in a rural county in Kenya. AB - Background: Many factors contribute to an enhanced risk of infant HIV acquisition, two of which may include failure of a mother to disclose her HIV positive status to her partner and exclusion of male partners in preventing mother-to-child transmission of HIV (PMTCT) interventions. To justify why HIV programmes need to integrate male partner involvement and partner disclosure, we need to establish an association between the two factors and infant HIV acquisition. Objective: To determine whether failure to disclose an HIV-positive status to a male partner is associated with increased risk of infant HIV acquisition, and whether part of the association is explained by exclusion of male partner in PMTCT programmes. Methods: Using a case-control study design, we identified a total of 180 mother-baby pairs with HIV-exposed infants. Thirty-six pairs with HIV-positive babies (cases) were compared to 144 pairs with HIV negative babies (controls) on whether the mothers had disclosed their HIV status to their partner in order to determine whether a disclosure or lack of it contributed to increased risk of mother-to-child transmission of HIV (MTCT). Each case pair was matched to four control pairs from the same facility. Results: Overall, 16.7% of mothers had not disclosed their HIV status to their partners, the proportion being significantly more among cases (52.8% vs. 7.6%, p < 0.001). Non-disclosure was significantly associated with infant HIV acquisition (aOR 9.8 (3.0-26.3); p < 0.001) and male partner involvement partially mediated the effect of non-disclosure on infant HIV acquisition (indirect coefficient = 0.17, p < 0.005). Conclusions: Failure of an HIV-positive woman to disclose her status to her male partner and exclusion of male partners in PMTCT programmes are two social factors that may curtail success of interventions towards the goal of eliminating MTCT.

PMID- 29568629 TI - Disseminated cutaneous histoplasmosis with laryngeal involvement in a setting of immune reconstitution inflammatory syndrome. AB - Introduction: Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum. We report a case of disseminated cutaneous histoplasmosis with mucocutaneous involvement in an AIDS patient paradigmatic of the multifaceted nature of the disease, which is an expression of the immune reconstitution inflammatory syndrome (IRIS). Patient presentation: A 39-year-old man presented with a three month history of asymptomatic papules and nodules with necrotic centres involving the centrofacial region. The patient was diagnosed as being HIV-positive a month earlier and was commenced on antiretroviral treatment. Two weeks after the development of skin lesions, the patient complained of a sore throat and hoarseness of his voice. A fibre-optic laryngoscopy and biopsies of the skin, larynx and liver were performed. Management and outcome: The CD4 counts increased from 2 cells/uL to 124 cells/uL, whereas the viral load decreased from one million to less than 20 copies/mL. A fibre-optic laryngoscopy revealed a supraglottitis with ulceration on the epiglottis. Histology of the liver, larynx and sections of the skin demonstrated pandermal necrotising granulomatous inflammation. Grocott-Gomori methenamine silver and Periodic acid-Schiff (PAS) stains revealed a relative paucity of intracellular, narrow-neck budding fungal organisms. Culture findings confirmed the diagnosis of histoplasmosis. The patient was treated with intravenous amphotericin B for two weeks followed by oral itraconazole 100 mg twice a day, with an excellent response to treatment. Conclusion: We present this case to remind clinicians that disseminated histoplasmosis in AIDS patients may occur as an expression of IRIS. A sudden onset of hoarseness with cutaneous lesions in a patient with disseminated disease should alert one to possible laryngeal histoplasmosis. Prompt recognition and treatment will avert the potential fatal complications of this disease. PMID- 29568630 TI - Progress towards the 2020 targets for HIV diagnosis and antiretroviral treatment in South Africa. AB - Background: The UNAIDS targets for 2020 are to achieve a 90% rate of diagnosis in HIV-positive individuals, to provide antiretroviral treatment (ART) to 90% of HIV diagnosed individuals and to achieve virological suppression in 90% of ART patients. Objectives: To assess South Africa's progress towards the 2020 targets and variations in performance by province. Methods: A mathematical model was fitted to HIV data for each of South Africa's provinces, and for the country as a whole. Numbers of HIV tests performed in each province were estimated from routine data over the 2002-2015 period, and numbers of patients receiving ART in each province were estimated by fitting models to reported public and private ART enrolment statistics. Results: By the middle of 2015, 85.5% (95% CI: 84.5% - 86.5%) of HIV-positive South African adults had been diagnosed, with little variation between provinces. However, only 56.9% (95% CI: 55.3% - 58.7%) of HIV diagnosed adults were on ART, with this proportion varying between 50.8% in North West and 72.7% in Northern Cape. In addition, 78.4% of adults on ART were virally suppressed, with rates ranging from 69.7% in Limpopo to 85.9% in Western Cape. Overall, 3.39 million (95% CI: 3.26-3.52 million) South Africans were on ART by mid-2015, equivalent to 48.6% (95% CI: 46.0% - 51.2%) of the HIV-positive population. ART coverage varied between 43.0% in Gauteng and 63.0% in Northern Cape. Conclusion: Although South Africa is well on its way to reaching the 90% HIV diagnosis target, most provinces face challenges in reaching the remaining two 90% targets. PMID- 29568631 TI - HIV epidemic drivers in South Africa: A model-based evaluation of factors accounting for inter-provincial differences in HIV prevalence and incidence trends. AB - Background: HIV prevalence differs substantially between South Africa's provinces, but the factors accounting for this difference are poorly understood. Objectives: To estimate HIV prevalence and incidence trends by province, and to identify the epidemiological factors that account for most of the variation between provinces. Methods: A mathematical model of the South African HIV epidemic was applied to each of the nine provinces, allowing for provincial differences in demography, sexual behaviour, male circumcision, interventions and epidemic timing. The model was calibrated to HIV prevalence data from antenatal and household surveys using a Bayesian approach. Parameters estimated for each province were substituted into the national model to assess sensitivity to provincial variations. Results: HIV incidence in 15-49-year-olds peaked between 1997 and 2003 and has since declined steadily. By mid-2013, HIV prevalence in 15 49-year-olds varied between 9.4% (95% CI: 8.5%-10.2%) in Western Cape and 26.8% (95% CI: 25.8%-27.6%) in KwaZulu-Natal. When standardising parameters across provinces, this prevalence was sensitive to provincial differences in the prevalence of male circumcision (range 12.3%-21.4%) and the level of non-marital sexual activity (range 9.5%-24.1%), but not to provincial differences in condom use (range 17.7%-21.2%), sexual mixing (range 15.9%-19.2%), marriage (range 18.2% 19.4%) or assumed HIV prevalence in 1985 (range 17.0%-19.1%). Conclusion: The provinces of South Africa differ in the timing and magnitude of their HIV epidemics. Most of the heterogeneity in HIV prevalence between South Africa's provinces is attributable to differences in the prevalence of male circumcision and the frequency of non-marital sexual activity. PMID- 29568632 TI - Delays in switching patients onto second-line antiretroviral treatment at a public hospital in eThekwini, KwaZulu-Natal. AB - Background: South Africa has one of the largest antiretroviral treatment (ART) programmes globally. In addition to increasing access to ART, it is important that the health system also focuses on the appropriate management of patients who fail first-line ART. Delays in switching patients onto second-line ART can adversely affect patient outcomes. Aim: To identify the patient-related and programmatic factors that delay switching patients onto second-line ART, and to assess whether these delays contribute to subsequent virological failure. Methods: Clinical records of adult patients switched onto second-line ART between 2011 and 2014 at a public antiretroviral clinic were used to collect demographic, clinical, laboratory and programmatic data (availability of viral load results, inadequate patient follow-up, insufficient notes for effective follow-up). Data were analysed using univariate and multivariate logistic regression. Results: The median duration from the date of first and confirmatory documented high viral load (VL > 1000 copies/mL) to being switched to second-line ART was 13.2 months [interquartile range (IQR) 1.1-52.7 months] and 6.4 months (IQR 0-43.3 months), respectively. Inadequate prescriber notes for appropriate follow-up (p = 0.01) and unavailability of patients' viral load results (p = 0.02) were significantly associated with delays in switching to second-line ART. There was no significant association between the time taken to switch to second-line ART and subsequent virological failure. Conclusion: We observed lengthy delays in switching patients to second-line ART. Modifiable programmatic factors were found to be significantly associated with delays in switching to second-line ART. PMID- 29568633 TI - Actions of female sex workers who experience male condom failure during penetrative sexual encounters with clients in Cape Town: Implications for HIV prevention strategies. AB - Background: Condom failure has always been found to coexist with condom usage, especially among sex workers. Objective: To describe the actions of female sex workers when they are faced with situations of condom failure. Methods: Using the survey design, the participants were selected through the snowball sampling method. Their responses were obtained using a structured questionnaire. A total of 100 questionnaires were analysed. Results: With respect to the immediate actions of sex workers after condom failure, 36% of the respondents continued with the sexual encounter after noticing that the condom was broken. Another 36% stopped immediately when they noticed that the condom had failed, but replaced the condom; 13% of the participants stopped the sexual encounter completely; 3% applied vaginal spermicidal foam; and 5% of the respondents stopped immediately and took a douche when they had the chance. For the actions within the next 24 hours of experiencing condom failure with a client, 53% of the participants did nothing; 4% sought counsel from a professional; 3% of the respondents took alcohol or drugs to forget the incident, 25% went to the clinic for assistance and 8% offered other responses. Conclusion: While continuing the sexual encounter without replacing the condom, taking alcohol and drugs or doing nothing could increase the risk of contracting HIV; however, actions like stopping the sexual encounter completely and visiting a clinic or a professional could make a difference between staying HIV negative or seroconverting. There is a need for targeted intervention to address issues of inappropriate behaviours after experiencing condom failure. PMID- 29568634 TI - Patient and provider attitudes to emergency department-based HIV counselling and testing in South Africa. AB - Background: The national South African HIV Counselling and Testing (HCT) guidelines mandate that voluntary counselling and testing (VCT) should be offered in all healthcare facilities. Emergency departments (EDs) are at the forefront of many healthcare facilities, yet VCT is not routinely implemented in this setting. Methods: We conducted a cross-sectional study that surveyed patients and healthcare providers at a tertiary care ED in the spring and summer of 2016 to ascertain their attitudes to VCT in the ED. We also used two previously validated survey instruments to gather data on patients' HIV knowledge and providers' stigma against patients living with HIV, as we anticipated that these may have an impact on providers' and patients' attitudes to the provision of HIV testing within the ED, and may offer insights for future intervention development. Results: A total of 104 patients and 26 providers were enrolled in the study. Overall, patients responded more favourably to ED-based HIV testing (92.3%) compared to providers (only 40% responded favourably). When asked about potential barriers to receiving or providing HIV testing, 16.4% of patients and 24% of providers felt that the subject of HIV was too sensitive and 58.7% of patients and 80% of providers indicated that privacy and confidentiality issues would pose major barriers to implementing ED-based HIV testing. Conclusion: This study shows that while ED-based HIV testing is overall highly acceptable to patients, providers seem less willing to provide this service. The survey data also suggest that future development of ED-based testing strategies should take into consideration privacy and confidentiality concerns that may arise within a busy emergency care setting. Furthermore, every effort should be made to tackle HIV stigma among providers to improve overall attitudes towards HIV-positive individuals that present for care in the ED. PMID- 29568635 TI - Condom migration after introduction of pre-exposure prophylaxis among HIV uninfected adolescents in South Africa: A cohort analysis. AB - Background: Approximately 3 million adolescents and young adults (AYA), between the ages of 15 years and 24 years, are living with HIV in sub-Saharan Africa. The use of pre-exposure prophylaxis (PrEP) may be a promising HIV prevention tool to bridge the high-risk years of AYA between sexual debut and adulthood. Objectives: Concerns have been raised that the use of PrEP could lead to an increase in sexual risk behaviour and sexually transmitted infections in general and less condom use in particular among adolescents. Methods: This study assesses condom use among South African adolescents enrolled on a demonstration PrEP study, called Pluspills, being conducted in Cape Town and Soweto. A questionnaire on sexual risk behaviour was administered at baseline and after 4, 8 and 12 weeks. Three different questions on condom use were asked at each visit. Unless all answers indicated condom use at all times, a participant was scored 'at risk'. McNemar's tests and a Cochran's Q test were used to investigate changes in condom use over time. Results: We interviewed 148 adolescents (66% female) at baseline. Eighty-nine participants completed all visits. In this group, an increase in condom use was observed over the period of 12 weeks. Most participants who reported behavioural changes mentioned an increase in condom use. Conclusion: There was no sign of sexual risk compensation in the 12 weeks of the study. Observed increase in condom use can be explained by an increased awareness of personal HIV risk or by social desirability or recall biases. In future research, additional data including other biomarkers of unprotected sex and longer follow up time would be useful to help understand the relationship between PrEP use, sexual risk perception and consequent behaviours, especially in adolescents. PMID- 29568636 TI - Approach to acute kidney injury in HIV-infected patients in South Africa. AB - Background: HIV-infected patients have an increased risk of renal disease. Current first-line antiretroviral therapy contains tenofovir disoproxil fumarate (TDF), which has nephrotoxic potential, characterised by proximal tubular cell injury. This may result in acute kidney injury, chronic kidney disease or partial or complete Fanconi syndrome. Objectives: We reviewed the existing literature on acute kidney injury and TDF-associated nephrotoxicity with the aim of providing an approach to diagnosis and management, which is relevant to a general medical practitioner. Methods: We performed a broad literature search of biomedical databases including PubMed and ScienceDirect. Our search terms included, but were not limited to, 'tenofovir', 'nephrotoxicity', 'HIV', 'acute kidney injury' and 'renal tubular acidosis'.Our aim was not to generate a systematic literature review with weighted evidence, but rather to provide a review of best practice from a variety of sources. Where published studies were not available from the above databases, we relied on relevant textbooks and professional guidelines. Results: Potential nephrotoxicity is not an impediment to the widespread use of TDF in treating HIV infection, because most patients will tolerate the medication well. However, patients with advanced disease, low body weight, advanced age, pre existing kidney disease and concomitant use of other nephrotoxic medications are at increased risk of adverse renal events and may develop severe complications if not appropriately managed. These risk factors are unfortunately common in patients initiating antiretroviral therapy in South Africa. Conclusion: Prevention of renal damage by means of careful screening and monitoring of high risk patients is of paramount importance. Increased awareness of this problem and knowledge of how to manage kidney disease should be emphasised for general medical practitioners who work with HIV-infected patients. PMID- 29568637 TI - Late stage presentation of HIV-positive patients to antiretroviral outpatient clinic in Zambia. AB - Background: The World Health Organization (WHO) and the Zambian Ministry of Health set out new guidelines on combination antiretroviral therapy (cART) in 2013 expanding the eligibility criteria for patients with HIV. Objectives: The primary objective were to determine when cART was initiated in HIV-positive outpatients according to clinical and immunological criteria, and to identify what proportion of patients who were eligible for cART according to 2013 WHO and 2013 Zambian cART guidelines were currently on cART. Methodology: This was a clinical audit of HIV-positive outpatients attending the cART clinic at Ndola Central Hospital in Ndola, Zambia, with retrospective cross-sectional chart review and survey design. Data were collected from clinical records and interviews with patients. Results: A total of 99% of patients eligible for cART according to 2013 guidelines were on treatment. Clinical staging of patients at initiated on cART (n = 206) was as follows: 28% clinical stage I, 21% clinical stage II, 36% clinical stage III and 15% clinical stage IV. The median CD4 count when patients were started on cART was 147 cells/mm3. Conclusion: The results show that a majority of patients were initiated on cART late in their disease course according to immunological (CD4 < 200 cell/mm3) and clinical criteria (stage III or IV). However, the vast majority of patients eligible for cART were currently on treatment. The late initiation of cART appears to be a result of late diagnosis of HIV. PMID- 29568638 TI - The Botsha Bophelo Adolescent Health Study: A profile of adolescents in Soweto, South Africa. AB - Background: Youth between the ages of 15 years to 24 years account for almost half of new HIV infections in South Africa. Objectives: To describe the study details of the Botsha Bophelo Adolescent Health Study (BBAHS) which was an investigation of HIV risk among adolescents living in Soweto, South Africa. Methods: Eligibility criteria for the BBAHS included being 14 years - 19 years old and living in one of the 41 identified formal and informal areas in the township of Soweto. A cross-sectional survey was developed between investigators and an adolescent community advisory board consisting of previously validated scales and original questions including demographics, sexual and reproductive health, health service utilisation and psychosocial behaviours. Results: Between 2010 and 2012, interviewers administered surveys among 830 adolescents (57% females), whose median age was 17 years (Q1, Q3: 16, 18), and found that 43% of participants identified their ethnicity as Zulu, 52% reported high food insecurity, 37% reported at least one parent had died, 15% reported living in a shack and 83% identified as heterosexual. Over half of the participants (55%) reported ever having sex (49% of females and 64% of males), 11% of whom initiated sex at < 15 years of age (3% females and 21% males). Almost half (47%) reported ever testing for HIV, 3% (n = 12) of whom self-reported being HIV-positive and 33% (n = 4) were on antiretroviral therapy. Conclusion: Our study highlights important individual, relational and structural level determinants of HIV risk for adolescent men and women growing up within HIV hyperendemic settings. PMID- 29568639 TI - HIV-associated neurocognitive disorder in a KwaZulu-Natal HIV clinic: A prospective study. AB - Introduction: HIV-associated neurocognitive disorder (HAND) is a consequence of HIV infection of the central nervous system. The prevalence ranges between 15% and 60% in different settings. Objectives: This prospective study determined the prevalence of HAND at a peri-urban HIV clinic in KwaZulu-Natal. Factors associated with HAND were examined, alternate neurocognitive tools were tested against the international HIV dementia scale (IHDS) score and an association between HAND and non-adherence to antiretroviral therapy (ART) was explored. Methods: Between May 2014 and May 2015, 146 ART-naive outpatients were assessed for HAND. IHDS score <= 10 established a diagnosis of HAND. Functional capacity was assessed using Eastern Cooperative Oncology Group (ECOG) score. Chi-squared test was used to identify risk factors for HAND. The get-up-and-go test (GUGT) and Center for Epidemiological Studies Depression scale - revised (CESD-r) were tested against the IHDS. HIV viral load done six months after initiating ART was used as a surrogate marker for adherence to ART. Results: The prevalence of HAND was 53%. In total, 99.9% of patients with HAND had no functional impairment. Age > 50 years old was associated with HAND (p = 0.003). There was no correlation between the GUGT, CESD-r and the IHDS score. HAND was not associated with non adherence (p = 0.06). Conclusions: While the prevalence of HAND is high, it is not associated with functional impairment which suggests that asymptomatic neurocognitive impairment is prevalent. Age > 50 years old is a risk factor for HAND. The GUGT and CESD-r are not useful diagnostic tools for HAND. The relationship between HAND and non-adherence should be further explored. PMID- 29568640 TI - Multiple papular lesions in a patient with HIV and/or AIDS and coinfected with hepatitis B virus: Amyloidosis. AB - Introduction: The most common form of systemic amyloidosis is amyloid A induced by a chronic inflammation. In HIV-infected patients, elevated serum amyloid A levels might be associated with chronic inflammation. Patient presentation: A 43 year-old male patient was admitted to hospital with a complaint of papular lesions around his eyes, existing for four months. The patient is receiving antiretroviral therapy. HIV RNA was undetectable, and the CD4 count was 770 cells/mm3. He suffered from a bladder carcinoma for four years. On examination, periocular, perioral and anogenital papules, papular lesions in the meatus of external auditory canal, and intranasal polyps were observed. Management: Microscopic examination of the biopsy material taken from the periocular lesion and then from perianal polyps revealed eosinophilic deposition, and stained positively by Congo red. Serum amyloid A level was negative. Antiretroviral therapy was continued. Conclusion: A rare form of amyloidosis in a patient with HIV and/or AIDS and coinfected with hepatitis B virus (HBV) was presented here with cutaneous and mucosal lesions.

PMID- 29568643 TI - South African HIV self-testing policy and guidance considerations. AB - The gap in HIV testing remains significant and new modalities such as HIV self testing (HIVST) have been recommended to reach key and under-tested populations. In December 2016, the World Health Organization (WHO) released the Guidelines on HIV Self-Testing and Partner Notification: A Supplement to the Consolidated Guidelines on HIV Testing Services (HTS) and urged member countries to develop HIVST policy and regulatory frameworks. In South Africa, HIVST was included as a supplementary strategy in the National HIV Testing Services Policy in 2016, and recently, guidelines for HIVST were included in the South African National Strategic Plan for HIV, sexually transmitted infections and tuberculosis 2017 2022. This document serves as an additional guidance for the National HIV Testing Services Policy 2016, with specific focus on HIVST. It is intended for policy advocates, clinical and non-clinical HTS providers, health facility managers and healthcare providers in private and public health facilities, non-governmental, community-based and faith-based organisations involved in HTS and outreach, device manufacturers, workplace programmes and institutes of higher education. PMID- 29568645 TI - 'Scared of going to the clinic': Contextualising healthcare access for men who have sex with men, female sex workers and people who use drugs in two South African cities. AB - Background: Men who have sex with men (MSM), sex workers (SW) and people who use drugs (PWUD) are at increased risk for HIV because of multiple socio-structural barriers and do not have adequate access to appropriate HIV prevention, diagnosis and treatment services. Objective: To examine the context of access to healthcare experienced by these three 'Key Populations', we conducted a qualitative study in two South African cities: Bloemfontein in the Free State province and Mafikeng in the North West province. Method: We carried out in-depth interviews to explore healthcare workers' perceptions, beliefs and attitudes towards Key Populations. Focus group discussions were also conducted with members of Key Populations exploring their experiences of accessing healthcare. Results: Healthcare workers described their own attitudes towards Key Populations and demonstrated a lack of relevant knowledge, skills and training to manage the particular health needs and vulnerabilities facing Key Populations. Female SW, MSM and PWUD described their experiences of stigmatisation, and of being made to feel guilt, shame and a loss of dignity as a result of the discrimination by healthcare providers and other community. members. Our findings suggest that the uptake and effectiveness of health services amongst Key Populations in South Africa is limited by internalised stigma, reluctance to seek care, unwillingness to disclose risk behaviours to healthcare workers, combined with a lack of knowledge and understanding on the part of the broader community members, including healthcare workers. Conclusion: This research highlights the need to address the broader healthcare provision environment, improving alignment of policies and programming in order to strengthen provision of effective health services that people from Key Populations will be able to access. PMID- 29568644 TI - Adult antiretroviral therapy guidelines 2017. AB - These guidelines are intended as an update to those published in the Southern African Journal of HIV Medicine in 2014 and the update on when to initiate antiretroviral therapy in 2015. Since the release of the previous guidelines, the scale-up of antiretroviral therapy (ART) in southern Africa has continued. New antiretroviral drugs have become available with improved efficacy, safety and robustness. The guidelines are intended for countries in the southern African region, which vary between lower and middle income. PMID- 29568646 TI - Risky sexual behaviour and human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) among healthcare workers. AB - Background: South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives: Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS affected countries. Methods: This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Results: Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion: More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care. PMID- 29568647 TI - Modelling the human immunodeficiency virus (HIV) epidemic: A review of the substance and role of models in South Africa. AB - We review key mathematical models of the South African human immunodeficiency virus (HIV) epidemic from the early 1990s onwards. In our descriptions, we sometimes differentiate between the concepts of a model world and its mathematical or computational implementation. The model world is the conceptual realm in which we explicitly declare the rules - usually some simplification of 'real world' processes as we understand them. Computing details of informative scenarios in these model worlds is a task requiring specialist knowledge, but all other aspects of the modelling process, from describing the model world to identifying the scenarios and interpreting model outputs, should be understandable to anyone with an interest in the epidemic. PMID- 29568648 TI - Barriers to Diagnosis Access for Chagas Disease in Colombia. AB - Chagas disease is the leading cause of nonischemic cardiomyopathy in Latin America. Timely access to diagnosis and trypanocidal treatment and preventive tools for millions of infected people continues to be a challenge. The purpose of this study was to identify potential barriers for the diagnosis of Chagas disease in Colombia from the perspective of healthcare providers. Using a simultaneous mixed-methods study design, we analyzed trends in access to screening and diagnosis for Chagas disease in Colombia and assessed the national barriers to access. The main barriers to access at the national level included a limited governmental public health infrastructure for the diagnosis of Chagas disease and limited physician awareness and knowledge of the disease. Data indicate that 1.5% of total expected cases based on national prevalence estimates were reported. Few public health laboratories have the capacity to perform complementary tests for the diagnosis of Chagas disease and almost 6 months elapse between the requests of the tests and the confirmation of the disease. This study shows that infected people must overcome a number of barriers to achieve diagnosis. Reducing barriers to early diagnosis of Chagas disease is an important goal in the fight against the disease. PMID- 29568649 TI - Relation of Food Insecurity and Hemoglobin Level in Preschool Aged Children. AB - Background: The iron deficiency anemia is a worldwide public problem, especially in developing countries, related to increased body needs and inadequate supply of iron from the diet. Objective: To analyze the association of food insecurity with hemoglobin concentration and the prevalence of anemia in preschool aged children in the city of Taubate, Sao Paulo, Brazil. Methods: A cross-sectional study was conducted with 306 children of preschool age. The nutritional status was assessed according to hemoglobin level and anthropometric indicators. Socioeconomic data and Brazilian Household Food Insecurity Measurement Scale (EBIA) results were obtained from interview with parents. Results: The prevalence of anemia was around 19% of preschool aged children and 41.2% families presented food insecurity. The anthropometric indicators were not associated with food insecurity and even though the bivariate analysis demonstrated that mild food insecurity affects the hemoglobin level, after adjusting the multivariate model this association lost significance (p > 0.05). Conclusion: The prevalence of anemia of 19.2% and the household food insecurity was found among 42.2% of the population. PMID- 29568650 TI - Radical Gastrectomy: Still the Cornerstone of Curative Treatment for Gastric Cancer in the Perioperative Chemotherapy Era-A Single Institute Experience over a Decade. AB - Background and Objectives: Most gastric cancer patients now undergo perioperative chemotherapy (POCT) based on the MAGIC trial results. POCT consists of neoadjuvant chemotherapy (NACT) as well as postoperative adjuvant chemotherapy. This study assessed the applicability of perioperative chemotherapy and the impact of radical gastrectomy encompassing a detailed lymph-node resection on outcomes of gastric cancer. Methods: Medical and pathology records of all gastric carcinoma resections were reviewed from 2006 onwards. Pathological details, number of lymph-nodes resected, and proportion of involved nodes, reasons for nonadministration of NACT, complications, recurrence, and survival data were analysed. Results: Only twenty-eight (37.8%) out of 74 patients underwent NACT and only nine completed POCT. NACT was declined due to comorbidities/patient refusal n = 24, early stage n = 14, and emergency presentation n = 8. Patients receiving NACT were much younger. Anastomotic leaks, hospital-mortality, lymph node yield, and proportion of involved lymph-nodes were similar in both groups. Thirty-two patients died due to recurrence with lymph-node involvement heralding higher recurrence risk and much poorer survival (HR 2.66; p = 0.013). Conclusion: More than 60% patients with resectable gastric carcinoma did not undergo NACT. Radical gastrectomy with lymphadenectomy remained the cornerstone of treatment in this period.

AB - Visual evoked potential (VEP) is a technique used to assess the brain's electrical response to visual stimuli. The aims of this study were to examine neural transmission within the visual pathway through VEP testing in preschool children with autism spectrum disorder (ASD) and compare it to age-matched controls, as well as search for a correlation between the VEP parameters and the symptoms of ASD. Participants were composed of ASD children (9 males) and typically developing children (8 males and 4 females), aged between 3 and 5 years. Checkerboards were chosen as the pattern-reversal VEP. The clinical severity of ASD was assessed using the Autism Treatment Evaluation Checklist (ATEC) and the Vineland Adaptive Behavior Scales 2nd edition (VABS-II). Our findings demonstrated that children with ASD had significantly longer N145 latency compared to the controls. A longer N145 latency correlated with a higher score of ATEC within the sensory/cognitive awareness subdomain. In addition, a slower N145 response was also associated with a lower VABS-II score within the socialization domain. The correlation between longer VEP latency and abnormal behaviors in children with ASD suggests a delayed neural communication within other neural circuits, apart from the visual pathway. These lines of evidence support the possibility of using VEP, along with clinical parameters, for the assessment of ASD severity.

A number of reasons complicate the diagnosis, as bovine brucellosis can be diagnosed by various serological tests. But the tests have a limitation; when the organism remains intracellular, the disease goes into chronic stage and the antibody titres may decline. The present study was conducted for isolation and detection of Brucella spp. by polymerase chain reaction (PCR) from seronegative cows. A total of 360 dairy cows from three geographical regions were screened serologically by Rose Bengal Plate Test (RBPT) where 24 samples were serologically positive and the rest of the samples were serologically negative. Among the 24 seropositive individuals, 11 were culture positive and 6 were culture positive from serologically negative dairy cows. The overall seroprevalence of brucellosis in cattle was 6.6% and in disease condition a higher prevalence was recorded in abortion (28.07%) followed by infertility (13.33%). To confirm the Brucella spp. in seronegative dairy cattle, the isolates were extracted and PCR was conducted, which produced 905 bp amplicon size of 6 Brucella spp. from milk sample. So, for the detection or eradication of brucellosis, a bacteriological test and a PCR technique should be performed with the serological test of milk. PMID- 29568652 TI - Imagine the Superiority of Dry Powder Inhalers from Carrier Engineering. AB - Inhalation therapy has strong history of more than 4000 years and it is well recognized around the globe within every culture. In early days, inhalation therapy was designed for treatment of local disorders such as asthma and other pulmonary diseases. Almost all inhalation products composed a simple formulation of a carrier, usually alpha-lactose monohydrate orderly mixed with micronized therapeutic agent. Most of these formulations lacked satisfactory pulmonary deposition and dispersion. Thus, various alternative carrier's molecules and powder processing techniques are increasingly investigated to achieve suitable aerodynamic performance. In view of this fact, more suitable and economic alternative carrier's molecules with advanced formulation strategies are discussed in the present review. Furthermore, major advances, challenges, and the future perspective are discussed. PMID- 29568654 TI - Hepatotoxicity of Nonsteroidal Anti-Inflammatory Drugs: A Systematic Review of Randomized Controlled Trials. AB - Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used medication in several countries, including Thailand. NSAIDs have been associated with hepatic side effects; however, the frequency of these side effects is uncertain. Aim of the Review: To systematically review published literature on randomized, controlled trials that assessed the risk of clinically significant hepatotoxicity associated with NSAIDs. Methods: Searches of bibliographic databases EMBASE, PubMed, and the Cochrane Library were conducted up to July 30, 2016, to identify randomized controlled trials of ibuprofen, naproxen, diclofenac, piroxicam, meloxicam, mefenamic acid, indomethacin, celecoxib, and etoricoxib in adults with any disease that provide information on hepatotoxicity outcomes. Results: Among the 698 studies, 18 studies met the selection criteria. However, only 8 studies regarding three NSAIDs (celecoxib, etoricoxib, and diclofenac) demonstrated clinically significant hepatotoxic evidence based on hepatotoxicity justification criteria. Of all the hepatotoxicity events found from the above-mentioned three NSAIDs, diclofenac had the highest proportion, which ranged from 0.015 to 4.3 (*10-2), followed by celecoxib, which ranged from 0.13 to 0.38 (*10-2), and etoricoxib, which ranged from 0.005 to 0.930 (*10-2). Conclusion: Diclofenac had higher rates of hepatotoxic evidence compared to other NSAIDs. Hepatotoxic evidence is mostly demonstrated as aminotransferase elevation, while liver-related hospitalization or discontinuation was very low. PMID- 29568655 TI - Posaconazole-Induced Adrenal Insufficiency in a Case of Chronic Myelomonocytic Leukemia. AB - Introduction: Posaconazole is an azole used in treatment and prophylaxis of a broad spectrum of fungal infections. Antifungals such as ketoconazole have been shown to cause primary adrenal insufficiency (AI) as a result of direct inhibition on the steroidogenesis pathway. There is only one reported case of primary AI induced by posaconazole in a patient with mucormycosis. We report a case of posaconazole-related primary AI. Case: A 63-year-old man with chronic myelomonocytic leukemia was admitted for fatigue and intermittent nausea and vomiting. He had recently discontinued prophylactic posaconazole 300 mg daily. He was assessed for AI with a morning cortisol of 1.9 mcg/dL followed by a failed cosyntropin stimulation (CS) test. Adrenocorticotropic hormone (ACTH) level was 154.6 pg/mL with negative 21-hydroxylase antibodies. The patient's symptoms improved with initiation of hydrocortisone and fludrocortisone. One year after discontinuation of posaconazole, he underwent a repeat CS test which showed normal adrenal function with normal ACTH at 34.1 pg/mL. Conclusion: In this case, we demonstrate that prolonged use of posaconazole is associated with primary AI. As use of posaconazole increases, knowledge of the potential risk of AI is important and must be included in the differential diagnosis when these patients present with hypotension, hypoglycemia, and failure to thrive. PMID- 29568656 TI - Emotional Lability as a Unique Presenting Sign of Suspected Chronic Traumatic Encephalopathy. AB - Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease caused by head trauma. Diagnosis of this disease is difficult as reliable biomarkers have not been established and often this clinical entity is underappreciated with poor recognition of its clinical presentations (Lenihan and Jordan, 2015). The definitive diagnosis of CTE is determined by identification of neurofibrillary tangles in the perivascular space around the sulci in postmortem tissue (McKee et al., 2015). However, performing brain biopsies searching for neurofibrillary tangles is not a feasible option for early diagnosis. Thus, diagnosis of suspected CTE in the living has been based on clinical suspicion using proposed research criteria of clinical presentations. In addition, neuroimaging techniques have shown some promise in assisting diagnosis. Clinically, CTE is more commonly known to be associated with memory impairment and executive function disorder (Stern et al., 2013). However, here, we present two unique cases of prior professional football players where behavioral changes were the first identifying factors in clinical presentation and discuss possible neuroimaging options to help with CTE diagnosis. Because behavioral changes can be mistaken for other neuropsychological diseases, recognizing differing clinical constellations is critical to early diagnosis, early intervention, and improving patient care in suspected CTE. PMID- 29568657 TI - Use of Extracorporeal Membrane Oxygenation in Postpartum Management of a Patient with Pulmonary Arterial Hypertension. AB - Current guidelines do not recommend pregnancy in patients with pulmonary arterial hypertension (PAH). This is due to the associated high mortality, which both dissuades PAH patients from becoming pregnant and encourages termination of pregnancy due to high maternal mortality risk. As a result, there is a lack of data and, consequently, there are only general guidelines available for management of pregnancy in PAH patients. Additionally, novel therapeutic strategies such as extracorporeal membrane oxygenation (ECMO), although used in the management of nonpregnant PAH patients as a bridge to lung transplantation, have not been used to treat cardiopulmonary collapse in pregnant PAH patients. In an attempt to bridge this paucity of data, we report the successful use of ECMO in resuscitation and management of a pregnant PAH patient who experienced cardiopulmonary collapse following a caesarian section. PMID- 29568658 TI - Surgical Management of a Giant Adrenal Pseudocyst: A Case Report and Review of the Literature in the Last Decade. AB - Adrenal pseudocysts are rare entities and occurred in the 5th and the 6th decades of life. They are discovered accidentally, while appearing with nonspecific clinical and imaging findings. We report a case of a 28-year-old woman presented in our Emergency Department complaining about upper abdomen pain. Computed tomography revealed a hypodense cystic lesion containing hyperdense material. The size of a mass was 11. 7 * 9.3 * 6.6 cm in diameter close to the pancreas, but the origin was from the left adrenal gland. The mass was excised with surgical laparotomy. Giant adrenal pseudocysts are rare entities. Final diagnosis usually confirmed with the pathology examination. Management of such adrenal lesions depends on the unique characteristics, the surgeon's experience, and local resources. PMID- 29568659 TI - Primary Nocardia Infection Causing a Fluorodeoxyglucose-Avid Right Renal Mass in a Redo Lung Transplant Recipient. AB - Immunosuppression after lung transplantation may increase susceptibility to opportunistic infection and is associated with early and delayed deaths in lung transplant recipients. Factors that may predispose lung transplant recipients to opportunistic bacterial and fungal infections include prolonged corticosteroid use, renal impairment, treatment of acute rejection, and post-transplant diabetes mellitus. We present a unique case of a 63-year-old woman with diabetes mellitus who underwent redo lung transplantation. Three years after her right-sided single redo lung transplant, she presented with right-sided abdominal pain, nausea, and vomiting. Upon examination, computed tomography showed a 4.5 * 3.3 cm heterogeneous, enhancing right renal mass with a patent renal vein. Magnetic resonance imaging confirmed a T1/T2 hypointense, diffusion-restricting, right mid renal mass that was fluorodeoxyglucose-avid on positron emission tomography. We initially suspected primary renal cell carcinoma. However, after a right nephrectomy, no evidence of neoplasia was observed; instead, a renal abscess containing filamentous bacteria was noted, raising suspicion for infection of the Nocardia species. Special stains confirmed a diagnosis of Nocardia renal abscess. Computed tomography of the chest and brain revealed no lesions consistent with infection. We initiated a long-term therapeutic regimen of anti-Nocardia therapy with imipenem and trimethoprim-sulfamethoxazole. PMID- 29568660 TI - A Case of Early Stage Bladder Carcinosarcoma in Late Recurrence of Urothelial Carcinoma after Transurethral Resection. AB - Carcinosarcomas of the urinary bladder are rare biphasic neoplasms, consisting of both malignant epithelial and malignant mesenchymal components, and the prognosis of this tumor is unfavorable in most patients with even possibility of resection of disease. A 77-year-old male with a history of transurethral resection (TUR) of urothelial carcinoma (UC) of the bladder and adjuvant intravesical chemotherapy with pirarubicin 10 years ago revisited our department with a gross hematuria. Cystoscopy demonstrated an approximately 2.5 cm nonpapillary tumor on the right wall of the bladder. Pelvic MRI showed the tumor without extending the base of the bladder wall. The tumor could be completely removed with TUR. The malignant epithelial elements consisted of high-grade UC and the majority of mesenchymal components were fibrosarcomatous differentiation based on immunohistochemical studies. The tumor could be pathologically also suspected to be an early stage on TUR specimens. Although he has received no additional intervention due to the occurrence of myocardial infarction at three weeks after the TUR, he has been alive with no evidence of recurrence of the disease 27 months after the TUR. Some early stages of bladder carcinosarcoma might have a favorable prognosis without aggressive treatments.

AB - A 37-year-old male patient presented to the emergency department with fever, gross hematuria, and irritative lower urinary tract symptoms. Investigations revealed the presence of a large left bladder diverticulum superior and lateral to the left ureteral orifice without bladder outlet obstruction. Bladder diverticula in adults almost always present in the setting of bladder outlet obstruction. The finding of a congenital bladder diverticulum in an adult represents a rare clinical entity. PMID- 29568662 TI - S-Nitroso-N-acetyl-L-cysteine ethyl ester (SNACET) and N-acetyl-L-cysteine ethyl ester (NACET)-Cysteine-based drug candidates with unique pharmacological profiles for oral use as NO, H2S and GSH suppliers and as antioxidants: Results and overview. AB - S-Nitrosothiols or thionitrites with the general formula RSNO are formally composed of the nitrosyl cation (NO+) and a thiolate (RS-), the base of the corresponding acids RSH. The smallest S-nitrosothiol is HSNO and derives from hydrogen sulfide (HSH, H2S). The most common physiological S-nitrosothiols are derived from the amino acid L-cysteine (CysSH). Thus, the simplest S-nitrosothiol is S-nitroso-L-cysteine (CysSNO). CysSNO is a spontaneous potent donor of nitric oxide (NO) which activates soluble guanylyl cyclase to form cyclic guanosine monophosphate (cGMP). This activation is associated with multiple biological actions that include relaxation of smooth muscle cells and inhibition of platelet aggregation. Like NO, CysSNO is a short-lived species and occurs physiologically at concentrations around 1 nM in human blood. CysSNO can be formed from CysSH and higher oxides of NO including nitrous acid (HONO) and its anhydride (N2O3). The most characteristic feature of RSNO is the S-transnitrosation reaction by which the NO+ group is reversibly transferred to another thiolate. By this way numerous RSNO can be formed such as the low-molecular-mass S-nitroso-N-acetyl-L-cysteine (SNAC) and S-nitroso-glutathione (GSNO), and the high-molecular-mass S-nitrosol-L cysteine hemoglobin (HbCysSNO) present in erythrocytes and S-nitrosol-L-cysteine albumin (AlbCysSNO) present in plasma at concentrations of the order of 200 nM. All above mentioned RSNO exert NO-related biological activity, but they must be administered intravenously. This important drawback can be overcome by lipophilic charge-free RSNO. Thus, we prepared the ethyl ester of SNAC, the S-nitroso-N acetyl-L-cysteine ethyl ester (SNACET), from synthetic N-acetyl-L-cysteine ethyl ester (NACET). Both NACET and SNACET have improved pharmacological features over N-acetyl-L-cysteine (NAC) and S-nitroso-N-acetyl-L-cysteine (SNAC), respectively, including higher oral bioavailability. SNACET exerts NO-related activities which can be utilized in the urogenital tract and in the cardiovascular system. NACET, with high oral bioavailability, is a strong antioxidant and abundant precursor of GSH, unlike its free acid N-acetyl-L-cysteine (NAC). Here, we review the chemical and pharmacological properties of SNACET and NACET as well as their analytical chemistry. We also report new results from the ingestion of S-[15N]nitroso-N acetyl-L-cysteine ethyl ester (S15NACET) demonstrating the favorable pharmacological profile of SNACET. PMID- 29568663 TI - Tissue-based metabolite profiling and qualitative comparison of two species of Achyranthes roots by use of UHPLC-QTOF MS and laser micro-dissection. AB - Achyranthes bidentata and Achyranthes aspera are saponin and steroid rich medicinal plants, used extensively for therapeutic treatments in Traditional Chinese Medicine (TCM) and Ayurveda. A. bidentata is reported to be one of the rare and extensively exploited medicinal plant species that face the issue of being endangered. Finding qualitative substitute with identical phyto constituents contributing to similar composition and pharmacological benefits will help in reducing the burden of exploitation of the natural habitats of such plants. In the present study, a comparative metabolite analysis of the whole drug and specific tissues isolated by laser micro-dissection (LMD) was carried out for both the selected species, by use of ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC-QTOF MS). The results of the study indicate that the cortex and the medullary ray tissues are rich in their content of steroidal and saponin constituents such as (25S)-inokosterone-20,22 acetonide, ginsenoside Ro, bidentatoside II and achyranthoside B. Metabolite profiling of the whole tissues of both the species indicates presence of identical constituents. Thus, it is inferred that A. bidentata and A. aspera can be used as qualitative substitutes for each other. PMID- 29568664 TI - A liquid chromatography with tandem mass spectrometry method for quantitating total and unbound ceritinib in patient plasma and brain tumor. AB - A rapid, sensitive, and robust reversed-phase liquid chromatography with tandem mass spectrometry method was developed and validated for the determination of total and unbound ceritinib, a second-generation ALK inhibitor, in patient plasma and brain tumor tissue samples. Sample preparation involved simple protein precipitation with acetonitrile. Chromatographic separation was achieved on a Waters ACQUITY UPLC BEH C18 column using a 4-min gradient elution consisting of mobile phase A (0.1% formic acid in water) and mobile phase B (0.1% formic acid in acetonitrile), at a flow rate of 0.4 mL/min. Ceritinib and the internal standard ([13C6]ceritinib) were monitored using multiple reaction monitoring mode under positive electrospray ionization. The lower limit of quantitation (LLOQ) was 1 nM of ceritinib in plasma. The calibration curve was linear over ceritinib concentration range of 1-2000 nM in plasma. The intra- and inter-day precision and accuracy were within the generally accepted criteria for bioanalytical method (<15%). The method was successfully applied to assess ceritinib brain tumor penetration, as assessed by the unbound drug brain concentration to unbound drug plasma concentration ratio, in patients with brain tumors. PMID- 29568665 TI - Denaturation studies on bovine serum albumin-bile salt system: Bile salt stabilizes bovine serum albumin through hydrophobicity. AB - Protein denaturation is under intensive research, since it leads to neurological disorders of severe consequences. Avoiding denaturation and stabilizing the proteins in their native state is of great importance, especially when proteins are used as drug molecules or vaccines. It is preferred to add pharmaceutical excipients in protein formulations to avoid denaturation and thereby stabilize them. The present study aimed at using bile salts (BSs), a group of well-known drug delivery systems, for stabilization of proteins. Bovine serum albumin (BSA) was taken as the model protein, whose association with two BSs, namely sodium cholate (NaC) and sodium deoxycholate (NaDC), was studied. Denaturation studies on the pre-formed BSA-BS systems were carried out under chemical and physical denaturation conditions. Urea was used as the chemical denaturant and BSA-BS systems were subjected to various temperature conditions to understand the thermal (physical) denaturation. With the denaturation conditions prescribed here, the data obtained is informative on the association of BSA-BS systems to be hydrophobic and this effect of hydrophobicity plays an important role in stabilizing the serum albumin in its native state under both chemical and thermal denaturation. PMID- 29568666 TI - Insight into the interaction of inhaled corticosteroids with human serum albumin: A spectroscopic-based study. AB - It is well known that the safety and efficacy profile of an inhaled cortocosteroid (ICS) is influenced by the pharmacokinetic properties and associated pharmacodynamic effects of the drug. Freely circulating, protein unbound, and active ICS can cause systemic adverse effects. Therefore, a detailed investigation of drug-protein interaction could be of great interest to understand the pharmacokinetic behaviour of corticosteroids and for the design of new analogues with effective pharmacological properties. In the present work, the interaction between some corticosteroids and human serum albumin (HSA) has been studied by spectroscopic approaches. UV-Vis spectroscopy confirmed that all the investigated corticosteroids can bind to HSA forming a protein-drug complex. The intrinsic fluorescence of HSA was quenched by all the investigated drugs, which was rationalized in terms of a static quenching mechanism. The thermodynamic parameters determined by the Van't Hoff analysis of the binding constants (negative DeltaH and DeltaS values) clearly indicate thathydrogen bonds and van der Waals forces play a major role in the binding process between albumin and betamethasone, flunisolide and prednisolone, while hydrophobic forces may play a major role in stabilizing albumin-triamcinolone complexes. PMID- 29568667 TI - Effect of nonionic surfactants in release media on accelerated in-vitro release profile of sirolimus eluting stents with biodegradable polymeric coating. AB - It is a well-known fact that sirolimus (SRL) undergoes degradation process via hydrolysis in aqueous media, leading to incorrect assessment of drug amount and thus release characteristics of formulations. The main objective of the present study was to evaluate the effect of nonionic surfactants in media on in-vitro release profiles for sirolimus eluting stents (SES) coated with biodegradable polymeric matrix. Phosphate buffer and acetate buffer incorporating nonionic surfactants with varying concentrations were examined for adequate solubility and stability (by RP-HPLC). Good sink condition was achieved in phosphate buffer (at pH 4.0) with 1.0% Tween 20, 1.0% Brij 35% and 0.5% Brij 58. Hydrodynamic size (by DLS) and the micelle-water partition coefficient (P) with standard free energy of solubilization (?Gs degrees ) of drug were evaluated to get some understanding about the solubilization phenomena. About 80% of drug release during the period of 48 h was achieved in optimized drug release media which was 1.0% Tween 20 in phosphate buffer pH 4.0. The obtained accelerated SRL release profile in optimized medium correlated well with the real time in-vitro release in phosphate buffer (pH 7.4). Surface morphology changes (by SEM), changes in gravimetric weights and molecular weight change (by GPC) were examined before and after drug release to understand the drug release mechanism which explains that the polymer did not undergo degradation during the drug release. PMID- 29568668 TI - Electrooxidation of sulfanilamide and its voltammetric determination in pharmaceutical formulation, human urine and serum on glassy carbon electrode. AB - For the first time, sulfanilamide (SFD) was determined in otologic solution, human urine and serum by electroanalytical techniques on glassy carbon electrode (GCE). The cyclic voltammetry (CV) experiments showed an irreversible oxidation peak at +1.06 V in 0.1 mol/L BRBS (pH = 2.0) at 50 mV/s. Different voltammetric scan rates (from 10 to 250 mV/s) suggested that the oxidation of SFD on the GCE was a diffusion-controlled process. Square-wave voltammetry (SWV) method under optimized conditions showed a linear response to SFD from 5.0 to 74.7 MUmol/L (R = 0.999) with detection and quantification limits of 0.92 and 3.10 MUmol/L, respectively. The developed SWV method showed better results for detection limit and linear range than the chronoamperometry method. It has been successfully applied to determine SFD concentration in pharmaceutical formulation, human urine and serum samples with recovery close to 100%. PMID- 29568669 TI - Synthesis of curcuminoid-imprinted polymers applied to the solid-phase extraction of curcuminoids from turmeric samples. AB - A molecular imprinting polymer technique was successfully applied to precipitation polymerization by using styrene as a functional monomer, curcuminoids as templates, acetonitrile as a porogenic solvent, benzoyl peroxide as the initiator, and ethylene glycol dimethacrylate as the crosslinker. The effects of interaction on the adsorption capacity of the molecularly imprinted polymer (MIP) and non-imprinted polymer (NIP) were investigated. A comparison of the adsorption capacity for MIP and NIP indicated that the NIP had the lowest adsorption capacity. The curcuminoid-imprinted polymer (Cur-MIP) was synthesized from 0.0237 mmol of styrene, 47.0 g of acetonitrile, 1.0238 mmol of ethylene glycol dimethacrylate, 0.0325 mmol of curcuminoids, and 0.2480 mmol of benzoyl peroxide. A high-performance liquid chromatography method with fluorescence detection was developed and validated for various chromatographic conditions for the determination of the curcuminoids in turmeric samples. The sample solution was separated using the Cur-MIP via solid-phase extraction and analyzed on a Brownlee analytical C18 column (150 mm * 6 mm, 5 um) using an isocratic elution consisting of acetonitrile and 0.1% trichloroacetic acid (40:60, v/v). The flow rate was maintained at 1.5 mL/min. The fluorescence detector was set to monitor at lambdaex = 426 nm and lambdaem = 539 nm. The quantification limit values were found to be 16.66, 66.66, and 33.33 ug/L for curcumin, demethoxycurcumin, and bisdemethoxycurcumin, respectively. Thus, we concluded that the Cur-MIP and high performance liquid chromatographic-fluorescence method could be applied to selective extraction and could be used as a rapid tool for the determination of curcuminoids in medicinal herbal extracts. PMID- 29568670 TI - Analysis of iodinated quorum sensing peptides by LC-UV/ESI ion trap mass spectrometry. AB - Five different quorum sensing peptides (QSP) were iodinated using different iodination techniques. These iodinated peptides were analyzed using a C18 reversed phase HPLC system, applying a linear gradient of water and acetonitrile containing 0.1% (m/v) formic acid as mobile phase. Electrospray ionization (ESI) ion trap mass spectrometry was used for the identification of the modified peptides, while semi-quantification was performed using total ion current (TIC) spectra. Non-iodinated peptides and mono- and di-iodinated peptides (NIP, MIP and DIP respectively) were well separated and eluted in that order. Depending on the used iodination method, iodination yields varied from low (2%) to high (57%). PMID- 29568671 TI - How do accountability problems lead to maternal health inequities? A review of qualitative literature from Indian public sector. AB - Background: There are several studies from different geographical settings and levels on maternal health, but none analyzes how accountability problems may contribute to the maternal health outcomes. This study aimed to analyze how accountability problems in public health system lead to maternal deaths and inequities in India. Methods: A conceptual framework was developed bringing together accountability process (in terms of standard setting, performance assessment, accountability (or answerability, and enforceability) -an ongoing cyclical feedback process at different levels of health system) and determinants of maternal health to analyze the influence of the process on the determinant leading to maternal health outcomes. A scoping review of qualitative and mixed methods studies from public health sector in India was conducted. A narrative and interpretive synthesis approach was applied to analyze data. Results: An overarching influence of health system-related factors over non-health system related factors leading to maternal deaths and inequities was observed. A potential link among such factors was identified with gaps in accountability functions at all levels of health system pertaining to policy gaps or conflicting/discriminatory policies and political commitment. A large number of gaps were also observed concerning performance or implementation of existing standards. Inherent to these issues was potentially a lack of proper monitoring and accountability functions. A critical role of power was observed influencing the accountability functions. Conclusion: The narrative and interpretive synthesis approach allowed to integrate and reframe the relevant comparable information from the limited empirical studies to identify the hot spots of systemic flaws from an accountability perspective. The framework highlighted problems in health system beyond health service delivery to wider areas such as policy or politics justifying their relevance and importance in such analysis. A crucial message from the study pertains to a need to move away from the traditional concept of viewing accountability as a blame-game approach and a concern of limited frontline health workers towards a constructive and systemic approach. PMID- 29568672 TI - U.S. Hospital Employment of Foreign-Educated Nurses and Patient Experience: A Cross-Sectional Study. AB - Introduction: For over half a century, hospitals in the United States have actively recruited foreign-educated nurses (FENs) in response to nurse shortages in hospitals and nursing homes. Little attention has been paid to the quality of care in the United States related to employment of FENs. Aims: The purpose of this retrospective study was to determine whether employment of FENs in U.S. hospitals is associated with patient care experience. Method: This study used cross-sectional data from three sources in 425 hospitals in four large states to evaluate the relationship between patient perceptions of care and hospital employment of FENs. The study linked data from publicly reported patient experience of care surveys, nurse surveys, and administrative data using unique hospital identifiers common across the data sets. Results: Patient-reported care experience was found to be more negative in hospitals employing more FENs, after controls for other possible explanations. Each 10% increase in FENs was associated with a decrease in the percentage of patients who would recommend their hospital and a decrease in the percentage of patients giving favorable reports on five nursing-specific aspects of patient experience. Conclusions: The results of this study suggest that employment of substantial numbers of nurses educated outside the United States may have implications for quality of care. The findings suggest that research on the outcomes of transition programs for FENs would be useful to inform regulatory policies. PMID- 29568673 TI - Biological Interpretation of Model-Reference Adaptive Control in a Mass Action Kinetics Metabolic Pathway Model. AB - The usefulness of control theory to model robustness in metabolic pathways is limited because controller properties and their implications on pathway regulation are unclear. Using sphingolipid biosynthesis in response to single gene overexpression as a case study, we apply model-reference adaptive control (MRAC) to model regulation in a mass action kinetics pathway model and report on its properties. Tracking error between treated cells (plant) and wild type (reference) is reduced in 9 of 10 system variables compared to using mass action kinetics only. This result is robust when system parameters are perturbed. Furthermore, we interpret control dynamics to infer potential regulatory interactions. Some observations are consistent with independent studies on the effects of the same experimental treatment, while others represent novel hypotheses that may be tested to yield additional biological insight. The usefulness and interpretation of MRAC to model metabolic pathway regulation is shown where plant dynamics approach the reference. PMID- 29568674 TI - Hippocampal atrophy, asymmetry, and cognition in type 2 diabetes mellitus. AB - Introduction: Type 2 diabetes mellitus is associated with global and hippocampal atrophy and cognitive deficits, and some studies suggest that the right hippocampus may display greater vulnerability than the left. Methods: Hippocampal volumes, the hippocampal asymmetry index, and cognitive functioning were assessed in 120 nondemented adults with long duration type 2 diabetes. Results: The majority of the sample displayed left greater than right hippocampal asymmetry (which is the reverse of the expected direction seen with normal aging). After adjustment for age, sex, and IQ, right (but not left) hippocampal volumes were negatively associated with memory, executive function, and semantic fluency. These associations were stronger with the hippocampal asymmetry index and remained significant for memory and executive function after additional adjustment for global brain atrophy. Conclusions: We conclude that asymmetric hippocampal atrophy may occur in type 2 diabetes, with greater atrophy occurring in the right than the left hippocampus, and that this may contribute to cognitive impairment in this disorder. These cross-sectional associations require further verification but may provide clues into the pathogenesis of cognitive disorders in type 2 diabetes. PMID- 29568675 TI - Combined prediction of miR-210 and miR-374a for severity and prognosis of hypoxic ischemic encephalopathy. AB - Background and Aim: Hypoxic-ischemic encephalopathy (HIE) is a disorder featured by hypoxic and ischemic damages during the perinatal period and its high mortality (i.e., 15%-20%) could be partly attributed to late diagnosis. Therefore, miR-210 and miR-374a were investigated to find if they could improve the diagnostic values of S100B protein and neuron-specific enolase (NSE) for HIE. Methods: Altogether 167 HIE newborns and 82 healthy newborns were recruited, and their blood were sampled for determining the levels of biomarkers. Specifically, S100B protein and NSE levels were detected based on the enzyme-linked immunosorbent assay (ELISA) kit, while the expressions of miR-210 and miR-374a were quantified by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Moreover, the receiver operating characteristic (ROC) curves were established to assess the diagnostic values of the above biomarkers for HIE. Finally, the correlation analysis between miR-210/miR-374 and Neonatal Behavioral Neurological Assessment (NBNA) scoring or Gesell intellectual development were also conducted. Results: The levels of miR-210, miR-374a, S100B protein, and NSE were significantly distinct between HIE patients and healthy newborns (p < .05). Besides, miR-210 (rs = .573), miR-374a (rs = .651), NSE level (rs = -.622), and S100B level (rs = -.55) were all, respectively, correlated with NBNA scoring with statistical significance (p < .05). Furthermore, it was revealed that the combined diagnosis of miR-210, miR-374a, S100B protein, and NSE could obtain the highest accuracy regarding pairs of mild HIE versus moderate HIE (AUC = 0.898), moderate HIE versus severe HIE (AUC = 0.922), mild HIE versus severe HIE (AUC = 0.996), and HIE versus control (AUC = 0.960). More than that, the four molecules were also remarkably associated with Gesell intellectual development (p < .05). Conclusion: MiR-210 and miR-374a could help to elevate the diagnostic value and prognostic prediction of S100B protein and NSE for HIE. PMID- 29568676 TI - Maternal separation affects expression of stress response genes and increases vulnerability to ethanol consumption. AB - Introduction: Maternal separation is an early life stress event associated with behavioral alterations and ethanol consumption. We aimed to expand the current understanding on the molecular mechanisms mediating the impact of postnatal stress on ethanol consumption. Methods: In the first experiment (T1), some of the pups were separated from their mothers for 6 hr daily (Maternal Separation group MS), whereas the other pups remained in the cage with their respective mothers (Control group - C). In the second experiment (T2), mice from both groups were subjected to the model of free-choice between water and sucrose solution or between water and ethanol solution. Maternal behavior was assessed at the end of T1. At the end of both T1 and T2, pups were subjected to the light/dark box behavioral test and blood corticosterone concentrations were analyzed. Results: Our maternal separation protocol led to intense maternal care and affected weight gain of the animals. The expression of stress response genes was altered with higher levels of Crh and Pomc being observed in the hypothalamus, and higher levels of Crhr1, Crhr2, Htr2a and lower levels of Nr3c1 and Htr1a being observed in the hippocampus after T1. At the end of T2, we observed higher levels of Avp and Pomc in the hypothalamus, and higher levels of Crhr1, Crhr2, Nr3c1, Slc6a4, Bdnf and lower levels of Htr1a in the hippocampus. Additionally, maternal separation increased vulnerability to ethanol consumption during adolescence and induced changes in anxiety/stress-related behavior after T2. Furthermore, voluntary ethanol consumption attenuated stress response and modified expression of reward system genes: enhancing Drd1 and Drd2, and reducing Gabbr2 in the striatum. Conclusion: Maternal separation induced behavioral changes and alterations in the expression of key genes involved in HPA axis and in the serotonergic and reward systems that are likely to increase vulnerability to ethanol consumption in adolescence. We demonstrated, for the first time, that ethanol consumption masked stress response by reducing the activity of the HPA axis and the serotonergic system, therefore, suggesting that adolescent mice from the MS group probably consumed ethanol for stress relieving purposes. PMID- 29568677 TI - Exploring cancer in LRRK2 mutation carriers and idiopathic Parkinson's disease. AB - Objectives: To compare the risk of non-skin cancer in LRRK2 mutation carriers and individuals with idiopathic Parkinson's disease (iPD), explore the age at which LRRK2 mutation carriers have cancer compared to iPD subjects, and clarify whether certain cancers are more closely associated with the LRRK2 mutation than iPD. Materials and Methods: Demographic data and cancer outcomes from 830 iPD patients and 103 LRRK2 mutation carriers (27 with PD) were retrospectively collected. Oncologic data were obtained from the Cancer Registry of Norway and included cancer type and age at cancer. All study participants were of Norwegian ethnicity. Results: LRRK2 mutation carriers have increased risk of non-skin cancer compared with iPD subjects (OR 2.09; 95% CI 1.16-3.77; p = .015). A significant association was found between the mutation and breast cancer in women (OR 4.58; 95% CI 1.45-14.51; p = .010). No other associations between harboring a LRRK2 mutation and specific cancer types were uncovered. Conclusion: LRRK2 mutation carriers have an increased risk of non-skin cancer compared with iPD subjects, which was mainly driven by the association between harboring the mutation and breast cancer in women. The increased risk is likely independent of ethnicity. PMID- 29568678 TI - Nonequivalent modulation of corticospinal excitability by positive and negative outcomes. AB - Objective: The difference between positive and negative outcomes is important in trial-and-error decision-making processes and affects corticospinal excitability. This study investigated corticospinal excitability during the performance of trial-and-error decision-making tasks with varying competing behavioral outcomes. Methods: Each trial began with one of five colored circles presented as a cue. Each color represented a different reward probability, ranging from 10% to 90%. The subjects were instructed to decide whether to perform wrist flexion in response to the cue. Two seconds after the presentation of the cue, a reward stimulus (picture of a coin) or penalty stimulus (mauve circle) was randomly presented to the subject. If the picture of a coin appeared, the subjects received the coin after the experiment if they had performed wrist flexion, but not if they had not performed wrist flexion. If a mauve circle appeared, a coin was deducted from the total reward if the subjects had performed wrist flexion, but not if they had not performed wrist flexion. One second after the reward or penalty stimulus, transcranial magnetic stimulation was delivered to the primary motor cortex at the midpoint between the centers of gravity of the flexor carpi radialis (agonist) and extensor carpi radialis (antagonist) muscles. Results: Cumulative wrist flexions were positively correlated with reward probabilities. Motor evoked potential (MEP) amplitudes in agonist muscles were significantly higher when wrist flexion incurred a penalty than when it incurred a reward, but there was no difference in the MEP amplitudes of antagonist muscles. Conclusion: Positive and negative behavioral outcomes differentially altered behavior and corticospinal excitability, and unexpected penalties had a stronger effect on corticospinal excitability for agonist muscles. PMID- 29568679 TI - Immediate and late outcomes of stenting for severe extracranial internal carotid artery stenosis in octogenarian patients. AB - Background: Multiple studies suggest that internal carotid artery stenting can be performed safely in octogenarians with low periprocedural complication rates. However, great concern still exists as to whether these patients will gain long term benefits from this procedure given their advanced age and uncertain life expectancy. We decided to conduct a retrospective study to determine short-and long-term clinical outcomes and to analyze survival duration in this population. Methods and Results: Sixty-nine consecutive elderly patients with either symptomatic or asymptomatic stenosis >=70% underwent 86 procedures. Immediate and late outcomes, as well as survival data, were analyzed retrospectively. Mean age was 83.1 +/- 2.7 years. Mean survival was 49.3 +/- 10.1 months. A complete neurological assessment was obtained at 1 and 2 years in 100% of patients, at 3 years in 90.7% of patients and at 5 years in 84.8% of patients. Two major and one minor ischemic strokes occurred during the periprocedural period. No death, myocardial infarction or intracranial hemorrhage was recorded. The mean follow-up period was 55.4 +/- 24.6 months. Four patients experienced a minimum of 1 year of follow-up, and the longest is 8 years. Among the patients with the longest follow up time, 6 had ischemic strokes, of which 2 were fatal. In total, 17 deaths occurred. Four patients experienced dementia without stroke. Survival at 3 and 5 years was estimated to be 90% and 73%, respectively. Conclusion: This study demonstrated that stenting in octogenarians was safe and effective during the periprocedural period. Long-term follow-up showed a low rate of fatal and nonfatal stroke, and patients survived long enough to benefit from the procedure. However, it was associated with a relatively high rate of long-term event. Though carotid artery stenting is a minimally invasive procedure, it should still be performed with great caution and only in carefully selected patients. The present study suggested that in this age population, carotid artery stenting might be considered as a revascularization option. PMID- 29568680 TI - Action video gaming and the brain: fMRI effects without behavioral effects in visual and verbal cognitive tasks. AB - Introduction: In this functional magnetic resonance imaging (fMRI) study, we compared task performance together with brain activation in a visuospatial task (VST) and a letter detection task (LDT) between longtime action video gamers (N = 14) and nongamers (N = 14) in order to investigate possible effects of gaming on cognitive and brain abilities. Methods: Based on previous research, we expected advantages in performance for experienced action video gamers accompanied by less activation (due to higher efficiency) as measured by fMRI in the frontoparietal attention network. Results: Contrary to these expectations, we did not find differences in overall task performance, nor in brain activation during the VST. We identified, however, a significantly different increase in the BOLD signal from a baseline task to the LDT in action video gamers compared with nongamers. This increased activation was evident in a number of frontoparietal regions including the left middle paracingulate cortex, the left superior frontal sulcus, the opercular part of the left inferior frontal gyrus, and the left and right posterior parietal cortex. Furthermore, we found increased activation in the triangular part of the left inferior frontal gyrus in gamers relative to nongamers when activation during the LDT was compared with activation during the VST. Conclusions: In sum, the expected positive relation between action video game experience and cognitive performance could not be confirmed. Despite their comparable task performance, however, gamers and nongamers exhibited clear-cut differences in brain activation patterns presumably reflecting differences in neural engagement, especially during verbal cognitive tasks. PMID- 29568681 TI - Role of sLOX-1 in intracranial artery stenosis and in predicting long-term prognosis of acute ischemic stroke. AB - Objective: The role of sLOX-1 in acute ischemic stroke still remains unclear. This study aims to demonstrate the value of sLOX-1 in evaluating degrees of intracranial artery stenosis and to predict prognosis in stroke. Methods: Two hundred and seventy-two patients were included in this study and basic data were collected within 72 hr on admission. We assessed the association between sLOX-1 levels and stroke conditions in one-year duration. After adjusting for potential confounders, regression analyses were performed. Results: We found that sLOX-1 levels were increased significantly in severe patients compared to the mild stroke group (p = .011). After adjusting confounders, sLOX-1 was associated with a poor functional outcome in patients with an adjusted OR of 2. 946 (95% CI, 1.788-4.856, p < .001). There was also positive correlation between sLOX-1 levels and the degrees of intracranial artery stenosis in the different groups (p = .029). Conclusions: Our study demonstrated that sLOX-1 levels could be used to evaluate the severity of stroke and the degrees of intracranial artery stenosis. Furthermore, sLOX-1 could be exploited to predict the long-term functional outcome of stroke. PMID- 29568682 TI - Bombesin receptor subtype-3-expressing neurons regulate energy homeostasis through a novel neuronal pathway in the hypothalamus. AB - Objectives: Bombesin receptor subtype-3 (BRS-3) has been suggested to play a potential role in energy homeostasis. However, the physiological mechanism of BRS 3 on energy homeostasis remains unknown. Thus, we investigated the BRS-3-mediated neuronal pathway involved in food intake and energy expenditure. Materials and Methods: Expression of BRS-3 in the rat brain was histologically examined. The BRS-3 neurons activated by refeeding-induced satiety or a BRS-3 agonist were identified by c-Fos immunostaining. We also analyzed expression changes in feeding-relating peptides in the brain of fasted rats administered with the BRS-3 agonist. Results: In the paraventricular hypothalamic nucleus (PVH), dorsomedial hypothalamic nucleus (DMH), and medial preoptic area (MPA), strong c-Fos induction was observed in the BRS-3 neurons especially in PVH after refeeding. However, the BRS-3 neurons in the PVH did not express feeding-regulating peptides, while the BRS-3 agonist administration induced c-Fos expression in the DMH and MPA, which were not refeeding-sensitive, as well as in the PVH. The BRS-3 agonist administration changed the Pomc and Cart mRNA level in several brain regions of fasted rats. Conclusion: These results suggest that BRS-3 neurons in the PVH are a novel functional subdivision in the PVH that regulates feeding behavior. As the MPA and DMH are reportedly involved in thermoregulation and energy metabolism, the BRS-3 neurons in the MPA/DMH might mediate the energy expenditure control. POMC and CART may contribute to BRS-3 neuron-mediated energy homeostasis regulation. In summary, BRS-3-expressing neurons could regulate energy homeostasis through a novel neuronal pathway. PMID- 29568683 TI - Chinese neurologists' perspective on intravenous thrombolysis for acute ischemic stroke. AB - Objectives: This study examined the neurologists' perspective toward intravenous thrombolysis for the treatment of acute ischemic stroke and the influencing factors in a Chinese Province. Methods: A cross-sectional study was conducted from 1 October 2014 to 31 January 2015. A total of 719 neurologists from 66 hospitals in Hubei Province were included. A questionnaire was designed, and multivariable logistic regression models were used to identify the factors associated with the neurologists' perspective toward intravenous thrombolysis. Results: Among the responding neurologists, 67.3% reported using intravenous thrombolysis and 32.9% believed the treatment was unsafe. Approximately 51.4% reported deficits in their knowledge of intravenous thrombolysis and 45.8% felt unconfident about their ability to employ the treatment. The majority (90.1%) supported hospitals in performing intravenous thrombolysis for eligible patients. Their safety concern was associated with hospital grade (odds ratio[OR] = 2.3; 95% confidence interval [CI], 1.4-3.7) and previous experiences with thrombolysis (OR = 3.1; 95% CI, 2.1-4.6). Their confidence was associated with their educational background (OR = 2.5; 95% CI, 1.3-4.5), knowledge mastery (OR = 10.4; 95% CI, 6.6-16.3), and previous experiences with thrombolysis (OR = 3.3; 95% CI, 2.1-5.3). Their attitudes were associated with gender (OR = 0.6; 95% CI, 0.3-1.0) and previous experiences with thrombolysis (OR = 4.9; 95% CI, 2.5-9.4). Conclusions: Most neurologists in Hubei Province, China, identified with intravenous thrombolysis for the treatment of acute ischemic stroke. However, they were weak in knowledge and lack confidence. Therefore, training, especially practical training, is needed to promote the use of thrombolysis in the region. PMID- 29568684 TI - Feedback from human posterior parietal cortex enables visuospatial category representations as early as primary visual cortex. AB - Introduction: Categorization is a fundamental cognitive process, whereby the brain assigns meaning to sensory stimuli. Previous studies have found category representations in prefrontal cortex and posterior parietal cortex (PPC). However, these higher-order areas lack the fine-scale spatial representations of early sensory areas, and it remains unclear what mechanisms enable flexible categorization based on fine-scale features. Methods: In this study, we decoded functional MRI signals and measured causal influences, across visual, parietal, and prefrontal cortex from participants performing categorization based on coarse or fine-scale spatial information in thirteen healthy adults. Results: We show that category information based on coarse discriminations was represented in the PPC, in the intraparietal sulcus region, IPS1/2, at an early stage of categorization trials, whereas representations of category information based on fine-scale discriminations formed later during interactions between IPS1/2 and primary visual cortex (V1). Specifically, when fine-scale discriminations were necessary, we decoded significant category information from V1 at an intermediate stage of trials and again from IPS1/2 at a late stage. IPS1/2 feedback was critical, because categorization performance improved as causal influence from IPS1/2 to V1 increased. Further, these mechanisms were plastic, as the selectivity of IPS1/2 and V1 responses shifted markedly with retraining to categorize the same stimuli into two new groups. Conclusions: Our findings suggest that reentrant processing between the PPC and visual cortex enables flexible abstraction of category information. PMID- 29568685 TI - Food-related salience processing in healthy subjects during word recognition: Fronto-parietal network activation as revealed by independent component analysis. AB - Background: The study aimed to isolate and localize mutually independent cognitive processes evoked during a word recognition task involving food-related and food-neutral words using independent component analysis (ICA) for continuously recorded EEG data. Recognition memory (old/new effect) involves cognitive subcomponents-familiarity and recollection-which may be temporally and spatially dissociated in the brain. Food words may evoke additional attentional salience which may interact with the old/new effect. Methods: Sixteen satiated female participants undertook a word recognition task consisting of an encoding phase (learning of presented words, 40 food-related and 40 food neutral) and a test phase (recognition of previously learned words and new words). Simultaneously recorded 64-channel EEG data were decomposed into mutually independent components using the Infomax algorithm in EEGLAB. The components were localized using single dipole fitting using a four-shell BESA head model. The resulting (nonartefactual) components with <15% residual variance were clustered across subjects using the kmeans algorithm resulting in five meaningful clusters localized to fronto-parietal regions. Repeated-measures anova was employed to test main effects (old/new and food relevance) and their interaction on cluster time courses. Results: Early task-relevant old/new effects were localized to the medial frontal gyrus (MFG) and later old/new effects to the right parietal regions (precuneus). Food-related (nontask-relevant) salience effects were localized to bilateral parietal regions (left precuneus and right postcentral gyrus). Food-related salience interacted with task relevance, the old/new effect in MFG being significant only for food-neutral words highlighting central the role of MFG as the converging site of endogenous and exogenous salience inputs. Conclusion: Our results indicate ICA to be a valid technique to decompose complex neurophysiological signals involving multiple cognitive processes and implicate the fronto-parietal network as an important attentional network for processing salience and task demands. PMID- 29568686 TI - Transthyretin familial amyloid polyneuropathy (TTR-FAP): Parameters for early diagnosis. AB - Background: Familial transthyretin amyloidosis is a life-threatening disease presenting with sensorimotor and autonomic polyneuropathy. Delayed diagnosis has a detrimental effect on treatment and prognosis. To facilitate diagnosis, we analyzed data patterns of patients with transthyretin familial amyloid polyneuropathy (TTR-FAP) and compared them to polyneuropathies of different etiology for clinical and electrophysiological discriminators. Methods: Twenty four patients with TTR-FAP and 48 patients with diabetic polyneuropathy (dPNP) were investigated (neurological impairment score NIS; neurological disability score NDS) in a cross-sectional design. Both groups were matched for gender and presence of pain. Quantitative sensory testing (QST), sympathetic skin response (SSR), heart rate variability (HRV), and nerve conduction studies (NCV) were performed. Both groups were compared using univariate analysis. In a stepwise discriminant analysis, discriminators between both neuropathies were identified. These discriminators were validated comparing TTR-FAP patients with a cohort of patients with chemotherapy-induced polyneuropathy (CIN) and chronic inflammatory demyelinating neuropathy (CIDP). Results: TTR-FAP patients scored higher in NDS and NIS and had impaired cold detection (CDT, p = .024), cold-warm discrimination (TSL, p = .019) and mechanical hyperalgesia (MPT, p = .029) at the hands, SSR (upper limb, p = .022) HRV and ulnar and sural NCS (all p < .05) were more affected in TTR-FAP. Ulnar nerve sensory NCV, CDT, and the MPT but not the other parameters discriminated TTR-FAP from dPNP (82% of cases), from CIN (86.7%) and from CIDP (68%; only ulnar sNCV). Conclusion: Low ulnar SNCV, impaired cold perception, and mechanical hyperalgesia at the hands seem to characterize TTR-FAP and might help to differentiate from other polyneuropathies. PMID- 29568687 TI - Effects of gender, digit ratio, and menstrual cycle on intrinsic brain functional connectivity: A whole-brain, voxel-wise exploratory study using simultaneous local and global functional connectivity mapping. AB - Introduction: Gender and sex hormones influence brain function, but their effects on functional network organization within the brain are not yet understood. Methods: We investigated the influence of gender, prenatal sex hormones (estimated by the 2D:4D digit ratio), and the menstrual cycle on the intrinsic functional network organization of the brain (as measured by 3T resting-state functional MRI (rs-fMRI)) using right-handed, age-matched university students (100 males and 100 females). The mean (+/-SD) age was 20.9 +/- 1.5 (range: 18-24) years and 20.8 +/- 1.3 (range: 18-24) years for males and females, respectively. Using two parameters derived from the normalized alpha centrality analysis (one for local and another for global connectivity strength), we created mean functional connectivity strength maps. Results: There was a significant difference between the male mean map and female mean map in the distributions of network properties in almost all cortical regions and the basal ganglia but not in the medial parietal, limbic, and temporal regions and the thalamus. A comparison between the mean map for the low 2D:4D digit ratio group (indicative of high exposure to testosterone during the prenatal period) and that for the high 2D:4D digit ratio group revealed a significant difference in the network properties of the medial parietal region for males and in the temporal region for females. The menstrual cycle affected network organization in the brain, which varied with the 2D:4D digit ratio. Most of these findings were reproduced with our other datasets created with different preprocessing steps. Conclusions: The results suggest that differences in gender, prenatal sex hormone exposure, and the menstrual cycle are useful for understanding the normal brain and investigating the mechanisms underlying the variable prevalence and symptoms of neurological and psychiatric diseases. PMID- 29568688 TI - A low-cost multimodal head-mounted display system for neuroendoscopic surgery. AB - Background: With rapid advances in technology, wearable devices as head-mounted display (HMD) have been adopted for various uses in medical science, ranging from simply aiding in fitness to assisting surgery. We aimed to investigate the feasibility and practicability of a low-cost multimodal HMD system in neuroendoscopic surgery. Methods: A multimodal HMD system, mainly consisted of a HMD with two built-in displays, an action camera, and a laptop computer displaying reconstructed medical images, was developed to assist neuroendoscopic surgery. With this intensively integrated system, the neurosurgeon could freely switch between endoscopic image, three-dimensional (3D) reconstructed virtual endoscopy images, and surrounding environment images. Using a leap motion controller, the neurosurgeon could adjust or rotate the 3D virtual endoscopic images at a distance to better understand the positional relation between lesions and normal tissues at will. Results: A total of 21 consecutive patients with ventricular system diseases underwent neuroendoscopic surgery with the aid of this system. All operations were accomplished successfully, and no system-related complications occurred. The HMD was comfortable to wear and easy to operate. Screen resolution of the HMD was high enough for the neurosurgeon to operate carefully. With the system, the neurosurgeon might get a better comprehension on lesions by freely switching among images of different modalities. The system had a steep learning curve, which meant a quick increment of skill with it. Compared with commercially available surgical assistant instruments, this system was relatively low-cost. Conclusions: The multimodal HMD system is feasible, practical, helpful, and relatively cost efficient in neuroendoscopic surgery. PMID- 29568689 TI - Both activated and less-activated regions identified by functional MRI reconfigure to support task executions. AB - Introduction: Functional magnetic resonance imaging (fMRI) has become very important for noninvasively characterizing BOLD signal fluctuations, which reflect the changes in neuronal firings in the brain. Unlike the activation detection strategy utilized with fMRI, which only emphasizes the synchronicity between the functional nodes (activated regions) and the task design, brain connectivity and network theory are able to decipher the interactive structure across the entire brain. However, little is known about whether and how the activated/less-activated interactions are associated with the functional changes that occur when the brain changes from the resting state to a task state. What are the key networks that play important roles in the brain state changes? Methods: We used the fMRI data from the Human Connectome Project S500 release to examine the changes of network efficiency, interaction strength, and fractional modularity contributions of both the local and global networks, when the subjects change from the resting state to seven different task states. Results: We found that, from the resting state to each of seven task states, both the activated and less-activated regions had significantly changed to be in line with, and comparably contributed to, a global network reconfiguration. We also found that three networks, the default mode network, frontoparietal network, and salience network, dominated the flexible reconfiguration of the brain. Conclusions: This study shows quantitatively that contributions from both activated and less activated regions enable the global functional network to respond when the brain switches from the resting state to a task state and suggests the necessity of considering large-scale networks (rather than only activated regions) when investigating brain functions in imaging cognitive neuroscience. PMID- 29568690 TI - Altered functional connectivity in blepharospasm/orofacial dystonia. AB - Introduction: Blepharospasm is characterized by involuntary eyelid spasms. It can be associated with perioral dystonia (Meige's syndrome or orofacial dystonia). We aimed at studying resting-state functional brain connectivity in these patients and its potential modulation by therapeutic botulinum toxin injections. Methods: We performed resting-state functional MRI and a region of interest-based analysis of functional connectivity in 13 patients with blepharospasm/Meige's syndrome in comparison to 13 healthy controls. Patients were studied before and 4 weeks after botulinum toxin treatment. Simultaneous facial electromyography was applied to control for involuntary facial movements. Results: Before botulinum toxin treatment, patients showed reduced functional connectivity between caudate and primary sensorimotor, somatosensory association and visual cortices as well as between putamen and parietal association cortex. Cerebellar areas displayed decreased functional connectivity to somatosensory and visual association cortices. On the cortical level, connectivity was reduced between the cingulate cortex and the primary sensorimotor/premotor and parietal association cortex, between premotor areas and the primary somatosensory cortices, and between the postcentral gyrus and temporoparietal, secondary somatosensory, cingular, and cerebellar regions. Botulinum toxin treatment modulated functional connectivity, especially between cerebellum and visual cortices. Conclusions: Patients with blepharospasm/Meige's syndrome show altered functional connectivity at rest in widespread brain regions including basal ganglia, cerebellar, primary/secondary sensorimotor, and visual areas. Functionally, this may reflect a predisposition for defective movement inhibition and sensorimotor integration. Botulinum toxin treatment could modulate brain connectivity in blepharospasm by altering visual and sensory input. PMID- 29568691 TI - Consistent hypersocial behavior in mice carrying a deletion of Gtf2i but no evidence of hyposocial behavior with Gtf2i duplication: Implications for Williams Beuren syndrome and autism spectrum disorder. AB - Introduction: Williams-Beuren syndrome (WBS) is a developmental disorder caused by hemizygous deletion of human chromosome 7q11.23. Hypersocial behavior is one symptom of WBS and contrasts with hyposociality observed in autism spectrum disorder (ASD). Interestingly, duplications of 7q11.23 have been associated with ASD. The social phenotype of WBS has been linked to GTF2I or general transcription factor IIi (TFII-I). Duplication of GTF2I has also been associated with ASD. Methods: We compared mice having either a deletion (Gtf2i+/- ) or duplication (Gtf2i+/dup ) of Gtf2i to wild-type (Gtf2i+/+ ) littermate controls in a series of behavioral tasks including open-field activity monitoring, olfactory probes, a social choice task, social transmission of food preference, habituation-dishabituation, and operant social motivation paradigms. Results: In open-field observations, Gtf2i+/- and Gtf2i+/dup mice demonstrated normal activity and thigmotaxis, and surprisingly, each strain showed a significant preference for a stimulus mouse that was not observed in Gtf2i+/+ siblings. Both Gtf2i+/- and Gtf2i+/dup mice demonstrated normal olfaction in buried food probes, but the Gtf2i+/- mice spent significantly more time investigating urine scent versus water, which was not observed in the other strains. Gtf2i+/- mice also spent significantly more time in nose-to-nose contact compared to Gtf2i+/+ siblings during the open-field encounter of the social transmission of food preference task. In operant tasks of social motivation, Gtf2i+/- mice made significantly more presses for social rewards than Gtf2i+/+ siblings, while there was no difference in presses for the Gtf2i+/dup mice. Discussion: Results were remarkably consistent across testing paradigms supporting a role for GTF2i in the hypersocial phenotype of WBS and more broadly in the regulation of social behavior. Support was not observed for the role of GTF2i in ASD. PMID- 29568693 TI - Acupuncture in the treatment of fatigue in Parkinson's disease: A pilot, randomized, controlled, study. AB - Introduction: Fatigue is a common and disabling problem in patients with Parkinson's disease (PD), and there is currently no satisfactory treatment. As acupuncture has been reported to be effective in fatigue related to other conditions, we sought to evaluate its efficacy in PD. Methods: This was a single center, randomized, sham-controlled study. Forty PD patients with moderately severe fatigue were randomized to receive 5 weeks of biweekly real or sham acupuncture. The primary outcome was change on the General Fatigue score of the Multidimensional Fatigue Inventory (MFI-GF) at 5 weeks. Secondary outcomes included MFI-Total score, Unified Parkinson's Disease Rating Scale Motor score (UPDRS Motor), Parkinson's Disease Questionnaire-39 (PDQ 39), Geriatrics Depression Scale (GDS), and Epworth Sleepiness Scale ESS). All outcome measures were evaluated at baseline, 5 and 9 weeks. Results: Both groups showed significant improvements in MFI-GF and MFI-Total scores at 5 and 9 weeks, but there were no significant between-group differences. There were no improvements from baseline for PDQ 39, GDS, and ESS. Although improvements were noted for the UPDRS Motor score in the real acupuncture group, no between-group difference could be demonstrated. Conclusions: Both real and sham acupuncture are equally effective in improving PD-related fatigue, and it is likely that this is due to nonspecific or placebo effects. PMID- 29568692 TI - Longitudinal evaluation of Tau-P301L transgenic mice reveals no cognitive impairments at 17 months of age. AB - Introduction: Tau is a microtubule-associated binding protein implicated in neurodegenerative tauopathies, including frontotemporal dementia (FTD) and Alzheimer's disease (AD). These diseases result in the intracellular accumulation of hyperphosphorylated tau in the form of neurofibrillary tangles, the presence of which is associated with cognitive deficits. Methods: We conducted a longitudinal behavioral study to provide a profile of the TgTau(P301L)23027 transgenic mouse in multiple cognitive domains across multiple ages. P301L is the tau mutation most frequently observed in patients with frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17) and this mouse model recapitulates the progressive development of glial and neurofibrillary tangles, and associated cerebral atrophy observed in patients. We examined frontal cortex dependent executive function and attention with the touchscreen 5-choice serial reaction time test (5-CSRTT) and assessed the function of temporal cortical structures using novel object recognition (OR). Results: Despite using sensitive tasks, there were no apparent changes in executive function, attention, or recognition memory in the transgenic mice from 5 to 17 months of age. Conclusions: This study represents the first comprehensive longitudinal analysis of cognition in the TgTauP301L mouse model and suggests that this model is not ideal for studying early attention and recognition memory impairments associated with tauopathy. However, spatial and object recognition memory impairments were observed during follow-up assessments when the mice were 18 and 21 months, respectively. These impairments are consistent with previous publications, and with a dementia-like phenotype in these mice when aged. PMID- 29568694 TI - Familial multiple sclerosis and association with other autoimmune diseases. AB - Objectives: Autoimmune diseases (AID) follow a complex, probably polygenic, pattern of inheritance and often cluster in families of patients with multiple sclerosis (MS). Our objective was to analyze family patterns and characteristics in families including more than one patient with MS. Materials and Methods: We analyzed personal and family history of neurological, systemic, and autoimmune diseases in 84 MS patients from 40 different families. Families were classified in two groups: families with cases of MS in at least two different generations (15 families) and families in which cases of MS belonged to only one generation (25 families). Results: The two previously established groups presented different clinical patterns and frequency of association with another AID. In one group, the second generation displayed a higher annual relapse rate than the first generation, higher frequency of progressive forms of MS, and more patients with another AID in addition to MS. Relapsing-remitting forms of MS (RRMS) were more frequent in the other group. Conclusions: Families that include more than one MS patient may show two distinct patterns. This finding seems important for the compression and analysis of genetic information on MS.

AB - Objects: To capture point mutations and short insertions/deletions in 49 previously reported genes associated with Parkinson's disease (PD) in a Chinese pedigree with early-onset Parkinson's disease (EOPD)-affected individuals. Methods: Clinical examinations and genomic analysis were performed on 21 subjects belonging to three generations of a Chinese family. Target region capture and high-throughput sequencing were used for screening 49 genes, which were previously reported to be associated with PD. The direct Sanger sequencing method in all subjects further verified the abnormal DNA fragments in the PARK2 gene. Results: Four family members, including a mother (I-1) and her three children (II 2, II-3, and II-7), were diagnosed with PD by clinical manifestations and/or PET/CT imaging analyses. Novel compound heterozygous mutations, consisting of a fragment deletion in exon 1 to 2 (EX 1-2 del) and a splicing point mutation c.619 1 (G > C) in the 6th intron of the PARK2 gene, were identified in II-2, II-3, and II-7. Individual EX 1-2 del or c.619-1 (G > C) mutations were detected in I-1 and the third generation (III-2, 3, 5, 10, and 11).Other mutations were not detected in the 49 known PD-associated genes. Conclusion: Novel compound heterozygous mutations were identified in a Chinese pedigree and might represent a cause of familial EOPD with autosomal dominant inheritance. PMID- 29568696 TI - Aplastic anemia secondary to nivolumab and ipilimumab in a patient with metastatic melanoma: a case report. AB - Background: Immune checkpoint blockade (ICB) is becoming an increasingly prevalent strategy in the clinical realm of cancer therapeutics. With more patients being administered ICB for a host of tumor types, the scope of adverse events associated with these drugs will likely grow. Here we report a case of aplastic anemia (AA) in a patient with metastatic melanoma secondary to dual ICB therapy. To our knowledge, this is only the second case of AA secondary to dual ICB in the literature, and the first to have a positive patient outcome. Case presentation: A 51-year old male with metastatic melanoma was started on dual immune checkpoint blockade, in the form ipilimumab (3 mg/kg) and nivolumab (1 mg/kg). Two weeks following the second cycle, he presented to the emergency department with profound polypipsia, polyuria and fatigue. The patient was diagnosed with diabetic ketoacidosis secondary to immune therapy induced type-1 diabetes and was admitted to the ICU. While in hospital the patient developed a symptomatic anemia and neutropenia. A bone marrow biopsy revealed a markedly hypocellular marrow with trinlineage hypoplasia with no evidence of myelodysplasia, neoplasm or excess blasts. Flow cytometry revealed an inverted CD4+:CD8+ ratio and an absence of hematogones. Taken together the presumed etiology was AA secondary to immunotherapy. The patient was subsequently started in IV methylprednisone 70 mg/day for 8 days, followed by a prednisone taper. This intervention rectified the bicytopenia and to date the patient has shown stable blood counts. Conclusion: With the use of ICBs becoming increasingly prevalent in the clinical arena, the number of patients presenting with immune-related adverse events will likely increase. The current case illustrates the need to be vigilant when managing cancer patients receiving ICB. The resolution of this patient's AA with corticosteroids highlights the value of early detection and appropriate treatment of these rare immune-mediated adverse events.

AB - Intergroup relation perspectives stem from research in Western contexts with clear distinctions between the dominant and nondominant groups. In South Africa, with at least 13 different cultural groups and 11 official languages, no group is dominant in all life spheres. We examine the relationship between identity and in /out-group orientation across Black-Zulu, Coloured (mixed racial ancestry), Indian, and White-Afrikaans emerging adults (N = 390; 75% females, Mage = 19.97 years, SD = 2.44). Results indicate that personal identity for all groups and ethnic identity for Black-Zulu, Indian, and White-Afrikaans emerging adults were important for intergroup relations. Black-Zulu, Coloured, and Indian emerging adults distinguish themselves less from others, whereas White-Afrikaans emerging adults are less open to others. Ultimately, the complexity of intergroup relations in South Africa has implications for the effective transformation interventions needed to counter experiences of threat and make group boundaries more flexible for emerging adults. PMID- 29568697 TI - Intratympanic (IT) Therapies for Meniere's Disease: Some Consensus Among the Confusion. AB - Purpose of Review: Aminoglycosides and corticosteroids are commonly used to treat Meniere's disease. Intratympanic (IT) administration of these medications allows high inner ear concentrations without significant adverse systemic effects. As a direct result, IT therapy has grown in popularity. Recent studies have compared patient outcomes between IT aminoglycosides and corticosteroids. This review summarizes these findings. Recent Findings: Trials comparing IT corticosteroids to IT placebo or oral therapy have had conflicting results. Most recently, Lambert et al. investigated the effect of IT dexamethasone in a sustained-release formulation compared to placebo. Their findings demonstrated improvement in some secondary measures of vertigo with the sustained-release formulation.IT gentamicin is known to be effective in controlling vertigo in Meniere's disease. In a recent study from 2016, Patel et al compared IT gentamicin and IT methylprednisolone in a double-blind, randomized controlled trial and identified no significant differences between the two in vertigo control. Summary: IT injections of aminoglycosides and corticosteroids can improve vertigo control. Hearing and vestibular loss however may result with IT aminoglycosides. Corticosteroids demonstrate limited hearing loss but may not have the same efficacy in controlling vertigo. Further investigation in the etiology of Meniere's disease is needed to tailor the proposed treatment to suit the disease mechanism. PMID- 29568699 TI - Anticipatory Emotion in Schizophrenia. AB - While people with schizophrenia report experiencing as much emotion in the presence of emotionally evocative stimuli as do people without schizophrenia, evidence suggests that they have deficits in the anticipation of positive emotion. However, little is known about the anticipation of negative emotion in schizophrenia, thus leaving open whether anticipation deficits are more general. We sought to assess anticipation of positive and negative stimuli across multiple methods of measurement. We measured reported experience and emotion modulated startle response in people with (n = 27) and without (n = 27) schizophrenia as they anticipated and subsequently viewed evocative pictures. People with schizophrenia showed an overall dampened response during the anticipation of positive and negative stimuli, suggesting a more general deficit in anticipatory emotional responses. Moreover, anticipatory responses were related to symptoms and functioning in people with schizophrenia. Together, these findings point to important new directions for understanding emotion deficits in schizophrenia. PMID- 29568700 TI - Capturing patient-reported area of knee pain: a concurrent validity study using digital technology in patients with patellofemoral pain. AB - Background: Patellofemoral pain (PFP) is often reported as a diffuse pain at the front of the knee during knee-loading activities. A patient's description of pain location and distribution is commonly drawn on paper by clinicians, which is difficult to quantify, report and compare within and between patients. One way of overcoming these potential limitations is to have the patient draw their pain regions using digital platforms, such as personal computer tablets. Objective: To assess the validity of using computer tablets to acquire a patient's knee pain drawings as compared to paper-based records in patients with PFP. Methods: Patients (N = 35) completed knee pain drawings on identical images (size and colour) of the knee as displayed on paper and a computer tablet. Pain area expressed as pixel density, was calculated as a percentage of the total drawable area for paper and digital records. Bland-Altman plots, intraclass correlation coefficient (ICC), Pearson's correlation coefficients and one-sample tests were used in data analysis. Results: No significant difference in pain area was found between the paper and digital records of mapping pain area (p = 0.98), with the mean difference = 0.002% (95% CI [-0.159-0.157%]). A very high agreement in pain area between paper and digital pain drawings (ICC = 0.966 (95% CI [0.93-0.98], F = 28.834, df = 31, p < 0.001). A strong linear correlation (R2 = 0.870) was found for pain area and the limits of agreement show less than +/-1% difference between paper and digital drawings. Conclusion: Pain drawings as acquired using paper and computer tablet are equivalent in terms of total area of reported knee pain. The advantages of digital recording platforms, such as quantification and reporting of pain area, could be realized in both research and clinical settings. PMID- 29568701 TI - Reliability and concurrent validity of the iPhone(r) Compass application to measure thoracic rotation range of motion (ROM) in healthy participants. AB - Background: Several water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify movement in various joints in the body; however, there appears to be a paucity of research using smartphones to assess thoracic spine movement. Therefore, the aim of this study is to determine the reliability (intra and inter rater) and validity of the iPhone(r) app (Compass) when assessing thoracic spine rotation ROM in healthy individuals. Methods: A total of thirty participants were recruited for this study. Thoracic spine rotation ROM was measured using both the current clinical gold standard, a universal goniometer (UG) and the Smart Phone Compass app. Intra-rater and inter-rater reliability was determined with a Intraclass Correlation Coefficient (ICC) and associated 95% confidence intervals (CI). Validation of the Compass app in comparison to the UG was measured using Pearson's correlation coefficient and levels of agreement were identified with Bland-Altman plots and 95% limits of agreement. Results: Both the UG and Compass app measurements both had excellent reproducibility for intra-rater (ICC 0.94 0.98) and inter-rater reliability (ICC 0.72-0.89). However, the Compass app measurements had higher intra-rater reliability (ICC = 0.96 - 0.98; 95% CI [0.93 0.99]; vs. ICC = 0.94 - 0.98; 95% CI [0.88-0.99]) and inter-rater reliability (ICC = 0.87 - 0.89; 95% CI [0.74-0.95] vs. ICC = 0.72 - 0.82; 95% CI [0.21 0.94]). A strong and significant correlation was found between the UG and the Compass app, demonstrating good concurrent validity (r = 0.835, p < 0.001). Levels of agreement between the two devices were 24.8 degrees (LoA -9.5 degrees , +15.3 degrees ). The UG was found to consistently measure higher values than the compass app (mean difference 2.8 degrees , P < 0.001). Conclusion: This study reveals that the iPhone(r) app (Compass) is a reliable tool for measuring thoracic spine rotation which produces greater reproducibility of measurements both within and between raters than a UG. As a significant positive correlation exists between the Compass app and UG, this supports the use of either device in clinical practice as a reliable and valid tool to measure thoracic rotation. Considering the levels of agreement are clinically unacceptable, the devices should not be used interchangeably for initial and follow up measurements. PMID- 29568702 TI - Linking influenza epidemic onsets to covariates at different scales using a dynamical model. AB - Background: Evaluating the factors favoring the onset of influenza epidemics is a critical public health issue for surveillance, prevention and control. While past outbreaks provide important insights for understanding epidemic onsets, their statistical analysis is challenging since the impact of a factor can be viewed at different scales. Indeed, the same factor can explain why epidemics are more likely to begin (i) during particular weeks of the year (global scale); (ii) earlier in particular regions (spatial scale) or years (annual scale) than others and (iii) earlier in some years than others within a region (spatiotemporal scale). Methods: Here, we present a statistical approach based on dynamical modeling of infectious diseases to study epidemic onsets. We propose a method to disentangle the role of covariates at different scales and use a permutation procedure to assess their significance. Epidemic data gathered from 18 French regions over six epidemic years were provided by the Regional Influenza Surveillance Group (GROG) sentinel network. Results: Our results failed to highlight a significant impact of mobility flows on epidemic onset dates. Absolute humidity had a significant impact, but only at the spatial scale. No link between demographic covariates and influenza epidemic onset dates could be established. Discussion: Dynamical modeling presents an interesting basis to analyze spatiotemporal variations in the outcome of epidemic onsets and how they are related to various types of covariates. The use of these models is quite complex however, due to their mathematical complexity. Furthermore, because they attempt to integrate migration processes of the virus, such models have to be much more explicit than pure statistical approaches. We discuss the relation of this approach to survival analysis, which present significant differences but may constitute an interesting alternative for non-methodologists. PMID- 29568703 TI - Curious creatures: a multi-taxa investigation of responses to novelty in a zoo environment. AB - The personality trait of curiosity has been shown to increase welfare in humans. If this positive welfare effect is also true for non-humans, animals with high levels of curiosity may be able to cope better with stressful situations than their conspecifics. Before discoveries can be made regarding the effect of curiosity on an animal's ability to cope in their environment, a way of measuring curiosity across species in different environments must be created to standardise testing. To determine the suitability of novel objects in testing curiosity, species from different evolutionary backgrounds with sufficient sample sizes were chosen. Barbary sheep (Ammotragus lervia) n = 12, little penguins (Eudyptula minor) n = 10, ringtail lemurs (Lemur catta) n = 8, red tailed black cockatoos (Calyptorhynchus banksia) n = 7, Indian star tortoises (Geochelone elegans) n = 5 and red kangaroos (Macropus rufus) n = 5 were presented with a stationary object, a moving object and a mirror. Having objects with different characteristics increased the likelihood individuals would find at least one motivating. Conspecifics were all assessed simultaneously for time to first orientate towards object (s), latency to make contact (s), frequency of interactions, and total duration of interaction (s). Differences in curiosity were recorded in four of the six species; the Barbary sheep and red tailed black cockatoos did not interact with the novel objects suggesting either a low level of curiosity or that the objects were not motivating for these animals. Variation in curiosity was seen between and within species in terms of which objects they interacted with and how long they spent with the objects. This was determined by the speed in which they interacted, and the duration of interest. By using the measure of curiosity towards novel objects with varying characteristics across a range of zoo species, we can see evidence of evolutionary, husbandry and individual influences on their response. Further work to obtain data on multiple captive populations of a single species using a standardised method could uncover factors that nurture the development of curiosity. In doing so, it would be possible to isolate and modify sub-optimal husbandry practices to improve welfare in the zoo environment. PMID- 29568704 TI - First endemic freshwater Gammarus from Crete and its evolutionary history-an integrative taxonomy approach. AB - The Mediterranean islands are known as natural laboratories of evolution with a high level of endemic biodiversity. However, most biodiversity assessments have focused mainly on terrestrial and marine fauna, leaving the freshwater animals aside. Crete is one of the largest islands in the Mediterranean Basin, with a long history of isolation from the continental mainland. Gammarid amphipods are often dominant in macrozoobenthic communities in European inland waters. They are widely used in biomonitoring and exotoxicological studies. Herein, we describe Gammarus plaitisi sp. nov., endemic to Cretan streams, based on morphological characters and a set of molecular species delimitation methods using mitochondrial cytochrome oxidase subunit I and 16S rRNA genes as well as nuclear 28S rDNA, ITS1 and EF1-alpha genes. The divergence of the new species is strongly connected with the geological history of the island supporting its continental origin. PMID- 29568705 TI - Activation of CD4 and CD8 T cell receptors and regulatory T cells in response to human proteins. AB - This study assessed in detail the influence of four different human proteins on the activation of CD4+ and CD8+ T lymphocytes and on the formation of regulatory T cells. Human whole-blood samples were incubated with four different human proteins. The effects of these proteins on the downstream immune-system response, on the expression of extracellular activation markers on and intracellular cytokines in T lymphocytes, and on the number of regulatory T cells (T-reg cells) were investigated via flow cytometry. Incubation with beta-actin or glyceraldehyde 3-phosphate dehydrogenase (GAPDH), which are cytoplasmic proteins, increased the expression of both extracellular activation markers (CD69 and HLA DR) and intracellular cytokines but did not significantly affect the number of T reg cells. In contrast, incubation with human albumin or insulin, which are serum proteins, reduced both extracellular activation markers and intracellular cytokine expression and subsequently increased the number of T-reg cells. These findings may help to explain the etiological basis of autoimmune diseases. PMID- 29568707 TI - Games between stakeholders and the payment for ecological services: evidence from the Wuxijiang River reservoir area in China. AB - A gambling or "game" phenomenon can be observed in the complex relationship between sources and receptors of ecological compensation among multiple stakeholders. This paper investigates the problem of gambling to determine payment amounts, and details a method to estimate the ecological compensation amount related to water resources in the Wuxijiang River reservoir area in China. Public statistics and first-hand data obtained from a field investigation were used as data sources. Estimation of the source and receptor amount of ecological compensation relevant to the water resource being investigated was achieved using the contingent valuation method (CVM). The ecological compensation object and its benefit and gambling for the Wuxijiang River water source area are also analyzed in this paper. According to the results of a CVM survey, the ecological compensation standard for the Wuxijiang River was determined by the CVM, and the amount of compensation was estimated. Fifteen blocks downstream of the Wuxijiang River and 12 blocks in the water source area were used as samples to administer a survey that estimated the willingness to pay (WTP) and the willingness to accept (WTA) the ecological compensation of Wuxijiang River for both nonparametric and parametric estimation. Finally, the theoretical value of the ecological compensation amount was estimated. Without taking other factors into account, the WTP of residents in the Wuxi River water source was 297.48 yuan per year, while the WTAs were 3864.48 yuan per year. The theoretical standard of ecological compensation is 2294.39-2993.81 yuan per year. Under the parameter estimation of other factors, the WTP of residents in the Wuxi River water source area was 528.72 yuan per year, while the WTA was 1514.04 yuan per year. The theoretical standard of ecological compensation is 4076.25-5434.99 yuan per year. The main factors influencing the WTP ecological compensation in the Wuxi River basin are annual income and age. The main factors affecting WTA are gender and attention to the environment, age, marital status, local birth, and location in the main village. PMID- 29568706 TI - Current state of knowledge on Wolbachia infection among Coleoptera: a systematic review. AB - Background: Despite great progress in studies on Wolbachia infection in insects, the knowledge about its relations with beetle species, populations and individuals, and the effects of bacteria on these hosts, is still unsatisfactory. In this review we summarize the current state of knowledge about Wolbachia occurrence and interactions with Coleopteran hosts. Methods: An intensive search of the available literature resulted in the selection of 86 publications that describe the relevant details about Wolbachia presence among beetles. These publications were then examined with respect to the distribution and taxonomy of infected hosts and diversity of Wolbachia found in beetles. Sequences of Wolbachia genes (16S rDNA, ftsZ) were used for the phylogenetic analyses. Results: The collected publications revealed that Wolbachia has been confirmed in 204 beetle species and that the estimated average prevalence of this bacteria across beetle species is 38.3% and varies greatly across families and genera (0 88% infected members) and is much lower (c. 13%) in geographic studies. The majority of the examined and infected beetles were from Europe and East Asia. The most intensively studied have been two groups of herbivorous beetles: Curculionidae and Chrysomelidae. Coleoptera harbor Wolbachia belonging to three supergroups: F found in only three species, and A and B found in similar numbers of beetles (including some doubly infected); however the latter two were most prevalent in different families. A total of 59% of species with precise data were found to be totally infected. Single infections were found in 69% of species and others were doubly- or multiply-infected. Wolbachia caused numerous effects on its beetle hosts, including selective sweep with host mtDNA (found in 3% of species), cytoplasmic incompatibility (detected in c. 6% of beetles) and other effects related to reproduction or development (like male-killing, possible parthenogenesis or haplodiploidy induction, and egg development). Phylogenetic reconstructions for Wolbachia genes rejected cospeciation between these bacteria and Coleoptera, with minor exceptions found in some Hydraenidae, Curculionidae and Chrysomelidae. In contrast, horizontal transmission of bacteria has been suspected or proven in numerous cases (e.g., among beetles sharing habitats and/or host plants). Discussion: The present knowledge about Wolbachia infection across beetle species and populations is very uneven. Even the basic data about infection status in species and frequency of infected species across genera and families is very superficial, as only c. 0.15% of all beetle species have been tested so far. Future studies on Wolbachia diversity in Coleoptera should still be based on the Multi-locus Sequence Typing system, and next-generation sequencing technologies will be important for uncovering Wolbachia relations with host evolution and ecology, as well as with other, co-occurring endosymbiotic bacteria. PMID- 29568708 TI - Cd and Zn interactions and toxicity in ectomycorrhizal basidiomycetes in axenic culture. AB - Background: Metal contamination in soils affects both above- and belowground communities, including soil microorganisms. Ectomycorrhizal (ECM) fungi are an important component in belowground community and tolerant strains have great potential in enhancing plant-based remediation techniques. We assessed cadmium and zinc toxicity in five ECM species in liquid media (Hebeloma subsaponaceum; H. cylindrosporum; H. crustuliniforme; Scleroderma sp.; Austroboletus occidentalis) and investigated the potential of Zn to alleviate Cd toxicity. Due to highly divergent results reported in the literature, liquid and solid media were compared experimentally for the first time in terms of differential toxicity thresholds in Cd and Zn interactions. Methods: A wide range of Cd and Zn concentrations were applied to ectomycorrhizal fungi in axenic cultures (in mg L 1): 0; 1; 3; 9; 27; 81; 243 for the Cd treatments, and 0; 1; 30; 90; 270; 810; 2,430 for Zn. Combined Zn and Cd treatments were also applied to H. subsaponaceum and Scleroderma sp. Dry weight was recorded after 30 days, and in case of solid medium treatments, radial growth was also measured. Results and Discussion: All species were adversely affected by high levels of Cd and Zn, and A. occidentalis was the most sensitive, with considerable biomass decrease at 1 mg L-1 Cd, while Scleroderma sp. and H. subsaponaceum were the most tolerant, which are species commonly found in highly contaminated sites. Cd was generally 10 times more toxic than Zn, which may explain why Zn had little impact in alleviating Cd effects. In some cases, Cd and Zn interactions led to a synergistic toxicity, depending on the concentrations applied and type of media used. Increased tolerance patterns were detected in fungi grown in solid medium and may be the cause of divergent toxicity thresholds found in the literature. Furthermore, solid medium allows measuring radial growth/mycelial density as endpoints which are informative and in this case appeared be related to the high tolerance indices found in H. subsaponaceum. PMID- 29568709 TI - Gender, age, and concomitant diseases of melanosis coli in China: a multicenter study of 6,090 cases. AB - Backgrounds and Aims: Melanosis coli (MC) is a noninflammatory, benign, and reversible colonic disorder, but its detection rates in China are unclear. We therefore aimed to analyze the epidemiological characteristics of MC in China. Methods: We assessed the detection rates, associated factors and concomitant diseases of MC in the patients who underwent colonoscopy at eight medical centers across five regions of China between January 2006 and October 2016. All data were procured from the electronic database established at each participating institutions. Results: Among the 342,922 included cases, MC was detected in 6,090 cases (detection rate = 1.78%, 95% confidence interval, 1.73%-1.82%) at a mean age of 60 years. The detection rate gradually increased yearly, and along with the increasing age regardless of gender, while a rapid increase presented in the patients >=60 years of age (0.58% for <=25 years, 1.22% for 25-59 years, and 3.19% for >=60 years). The detection rate was higher in females than in males; however, the rate of per-year increase was higher in males than in females at age of >=60 years, which was 1.85-fold of that in females. Among cancer, polyp, inflammation, and diverticula, polyp was the most common concomitant disease of MC and identified in 41.72% of MC patients. Conclusions: MC detection rates were increased annually and elevated in older patients, particularly in male patients. Males in the elderly population of >=60 years were most likely to have MC. Colonic polyp is the most common concomitant disease of MC. PMID- 29568710 TI - Effects of landscape features on population genetic variation of a tropical stream fish, Stone lapping minnow, Garra cambodgiensis, in the upper Nan River drainage basin, northern Thailand. AB - Spatial genetic variation of river-dwelling freshwater fishes is typically affected by the historical and contemporary river landscape as well as life history traits. Tropical river and stream landscapes have endured extended geological change, shaping the existing pattern of genetic diversity, but were not directly affected by glaciation. Thus, spatial genetic variation of tropical fish populations should look very different from the pattern observed in temperate fish populations. These data are becoming important for designing appropriate management and conservation plans, as these aquatic systems are undergoing intense development and exploitation. This study evaluated the effects of landscape features on population genetic diversity of Garra cambodgiensis, a stream cyprinid, in eight tributary streams in the upper Nan River drainage basin (n = 30-100 individuals/location), Nan Province, Thailand. These populations are under intense fishing pressure from local communities. Based on 11 microsatellite loci, we detected moderate genetic diversity within eight population samples (average number of alleles per locus = 10.99 +/- 3.00; allelic richness = 10.12 +/- 2.44). Allelic richness within samples and stream order of the sampling location were negatively correlated (P < 0.05). We did not detect recent bottleneck events in these populations, but we did detect genetic divergence among populations (Global FST = 0.022, P < 0.01). The Bayesian clustering algorithms (TESS and STRUCTURE) suggested that four to five genetic clusters roughly coincide with sub-basins: (1) headwater streams/main stem of the Nan River, (2) a middle tributary, (3) a southeastern tributary and (4) a southwestern tributary. We observed positive correlation between geographic distance and linearized FST (P < 0.05), and the genetic differentiation pattern can be moderately explained by the contemporary stream network (STREAMTREE analysis, R2 = 0.75). The MEMGENE analysis suggested genetic division between northern (genetic clusters 1 and 2) and southern (clusters 3 and 4) sub-basins. We observed a high degree of genetic admixture in each location, highlighting the importance of natural flooding patterns and possible genetic impacts of supplementary stocking. Insights obtained from this research advance our knowledge of the complexity of a tropical stream system, and guide current conservation and restoration efforts for this species in Thailand. PMID- 29568711 TI - Validation and application of the Chinese version of the Perceived Stress Questionnaire (C-PSQ) in nursing students. AB - Objective: To translate the Perceived Stress Questionnaire (PSQ) into Chinese, validate its reliability and validity in nursing students and investigate the perceived stress level of nursing students. Method: Forward- and back-translation combined with expert assessment and cross-cultural adaptations were used to construct the Chinese version of the PSQ (C-PSQ). This research adopted a stratified sampling method among 1,519 nursing students in 30 classes of Ningbo College of Health Sciences to assess the reliability and validity of the C-PSQ. Among them, we used the Recent C-PSQ (only the last month). Results: The C-PSQ retained all 30 items of the original scale. Principal component analysis extracted five factors that explained 52.136% of the total variance. The S CVI/Ave was 0.913. Concurrent validity was 0.525 and 0.567 for anxiety and depression respectively. The results of the confirmatory factor analysis were as follows: chi2/df = 4.376, RMR = 0.023, GFI = 0.921, AGFI = 0.907, CFI = 0.916, RMSEA = 0.048, PNFI = 0.832, PGFI = 0.782, CN = 342 and AIC/CAIC = 0.809. The scale's Cronbach's alpha was 0.922, and Cronbach's alpha of each dimension was 0.899 (worries/tension), 0.821 (joy), 0.688 (overload), 0.703 (conflict), 0.523 (self-realization). The correlation coefficient between the first and second test, the first and third test and the second and third test was 0.725, 0.787 and 0.731, respectively. Mean values and distribution of overall PSQ index in nursing students was 0.399 +/- 0.138. Different demographic factors were significantly associated with the perceived stress of nursing students. Conclusion: The C-PSQ has an appropriate reliability and validity, which means that the scale can be used as a universal tool for psychosomatic studies. The perceived stress of nursing students was relatively high. Further studies are needed. PMID- 29568712 TI - The association between elevated serum uric acid levels and islet beta-cell function indexes in newly diagnosed type 2 diabetes mellitus: a cross-sectional study. AB - Background: Serum uric acid (UA) has been reported as a risk factor for type 2 diabetes mellitus (T2DM). However, whether serum UA is associated with insulin resistance and insulin secretion, and the effect of gender on it in the case of the existed association, both remain undefined. Methods: A cross-sectional study was designed and performed, which enrolled a total of 403 newly diagnosed T2DM patients (mean age, 50.21 +/- 13.34 years (62.5% males)). Clinical characteristics and islet function indexes of all participants were analyzed based on gender-specific tertiles of serum UA levels. In addition, multiple linear regression analysis was conducted to investigate covariates associated with islet function indexes. Results: The mean levels of serum UA were 331.05 MUmol/L (interquartile range (IQR): 60.6, 400.9 MUmol/L) and 267.9 MUmol/L (IQR: 204.7, 331.9 MUmol/L) in men and women, respectively. The values of insulin secretion indexes involving AUCins30/glu30, AUCins120/glu120 and total insulin disposition index (DI120) in females were significantly higher than those in males. Apart from the homeostasis model assessment insulin resistance of men, serum UA was positively associated with insulin secretion and insulin resistance indexes both in men and women. Multivariable linear regression analysis showed serum UA exerted an independent impact on insulin secretion in females, but not on insulin resistance. In males, islet function was simultaneously affected by serum UA age, body mass index (BMI), and serum lipids. Conclusion: Serum UA harbored a positive correlation with insulin secretion and insulin resistance indexes in newly diagnosed T2DM patients, which was influenced by gender, BMI, serum lipids. Hence, serum UA may be considered as a predictor for islet function in clinical practice.

AB - In 2011, the US Food and drug Administration (FDA) developed a strategic plan for regulatory science that focuses on developing new tools, standards, and approaches to assess the safety, efficacy, quality, and performance of FDA regulated products. In line with this, the Division of Applied Regulatory Science was created to move new science into the Center for Drug Evaluation and Research (CDER) review process and close the gap between scientific innovation and drug review. The Division, located in the Office of Clinical Pharmacology, is unique in that it performs mission-critical applied research and review across the translational research spectrum including in vitro and in vivo laboratory research, in silico computational modeling and informatics, and integrated clinical research covering clinical pharmacology, experimental medicine, and postmarket analyses. The Division collaborates with Offices throughout CDER, across the FDA, other government agencies, academia, and industry. The Division is able to rapidly form interdisciplinary teams of pharmacologists, biologists, chemists, computational scientists, and clinicians to respond to challenging regulatory questions for specific review issues and for longer-range projects requiring the development of predictive models, tools, and biomarkers to speed the development and regulatory evaluation of safe and effective drugs. This article reviews the Division's recent work and future directions, highlighting development and validation of biomarkers; novel humanized animal models; translational predictive safety combining in vitro, in silico, and in vivo clinical biomarkers; chemical and biomedical informatics tools for safety predictions; novel approaches to speed the development of complex generic drugs, biosimilars, and antibiotics; and precision medicine. PMID- 29568714 TI - Oral Health Practices Among Pakistani Physicians. AB - Introduction In most healthcare models, the first interaction of a patient is with a general physician. The inspection of the oral cavity is a mandatory component of the general physical examination performed by a physician. This helps detect any oral pathology and make suitable referrals. Therefore, adequate oral health awareness is essential for physicians. Our study aimed at evaluating the oral health practices among physicians working in a private teaching setup in Islamabad, Pakistan. Methods A cross-sectional study involving 144 physicians teaching undergraduate medical students at Shifa College of Medicine and its affiliated hospital, Shifa International Hospital, was conducted. Participants were interviewed through a self-designed questionnaire. Later, each participant demonstrated their teeth brushing technique on a standard model of the oral cavity, which was assessed against a checklist conforming to the modified bass technique. A video clip showing the aforementioned brushing technique was shown at the end of the interview. The collected data was analyzed on IBM's statistical package for the social sciences (SPSS) version 21. Results Toothpaste was the top choice (97.2%) of teeth cleaning tool with 69% participants brushing their teeth two times a day and 56.9% using toothbrushes with bristles of medium texture. The use of mouthwash (32.6%) and dental floss (11.1%) was considerably low. Dental caries and teeth discoloration were seen in 46.5% and 43.8% physicians, respectively. An alarmingly low number of physicians (31.9%) claimed to have read guidelines regarding oral health. This translated into most participants (78.5%) visiting a dentist only when needed. Only 4.9% participants performed all components of the modified bass technique to clean teeth on the oral cavity model, with up to 22.9% unable to perform a single step accurately. Conclusion The oral health knowledge and practices of physicians were found to be suboptimal and necessitate the integration of oral health awareness in the medical curriculum. A multiprofessional approach with physicians in crucial roles is required to address the burden of dental diseases globally.

AB - As students in the health professions transition from the classroom into the clinical environment, they will be expected to effectively communicate with their team members and their patients. Effective communication skills are essential to their ability to effectively contribute to their clinical team and the patient care they deliver. The authors propose an interactive workshop that can support students' deliberate practice of communication skills. The authors designed a simulation workshop that affords students the opportunity to practice their communication and peer-to-peer coaching skills. Using LEGOs, a one-hour workshop was conducted with medical students. Students were divided into groups of two. Each student took on a different role: teacher or builder. Teachers were tasked with instructing builders on how to construct a pre-made LEGO structure, not allowing builders to look at the structure. A group debriefing followed to evaluate the activity and explore the themes that emerged. Twenty first-year medical students and 25 fourth-year medical students participated in this activity. Most groups were successful in reproducing the pre-made structure. Groups that pre-briefed before building were most successful. Unsuccessful groups did not define orientation or direction in mutually understood terms, resulting in the creation of an incorrect mirror image of the structure - a common phenomenon seen during the teaching of procedures in the clinical learning environment. The workshop was well received. Students made requests to have similar sessions throughout their training to better support the development of effective communication skills. The workshop can easily be applied to other specialties to assist with procedural skills instruction or in workshops focusing on effective communication. PMID- 29568716 TI - Cutaneous, Intranasal Blastomycosis Infection in Two Patients from Southern West Virginia: Diagnostic Dilemma. AB - Blastomycosis is a dimorphic fungus caused by the species of Blastomyces dermatitidisand Blastomyces gilchristii, which are endemic to the Ohio River and Mississippi River Valleys. It is commonly found in soil or decomposing wood. It is capable of infecting both immunocompromised and immunocompetent patients via the respiratory tract by inhaling conidia, where it may remain asymptomatic for a prolonged period of time. Extrapulmonary complications can occur in disseminated disease due to haematogenous spread from the lungs to other organ systems. Haematogenous dissemination from the lungs occurs most commonly to the skin. Although rare, primary cutaneous blastomycosis can also occur with direct inoculation through the trauma of the skin. Patients presenting with cutaneous blastomycosis are often misdiagnosed with malignant neoplasms and may not be appropriately managed until further testing and tissue biopsy. Currently, there are only four previous case reports of blastomycosis presenting in the intranasal region. We report two cases of cutaneous blastomycosis of the nasal passages and upper lip with pulmonary manifestations in Southern West Virginia. These patients first presented with cutaneous symptoms, which were originally treated for melanoma and squamous cell carcinoma and were later diagnosed with systemic blastomycosis. PMID- 29568717 TI - A Web-based Decision Tool to Estimate Subarachnoid Hemorrhage Risk in Emergency Department Patients. AB - Subarachnoid hemorrhage (SAH) from a leaking aneurysm is a neurological emergency. SAH patients often present with headache-a common chief complaint among emergency department patients. If unrecognized, 70% of the patients with re bleeds die and one third are left with neurological deficits. Therefore, it is critical to distinguish the signs and symptoms of SAH from benign causes of headache, perform the appropriate diagnostic tests and treat in a timely manner in order to reduce the disability and mortality associated with this condition. In patients with suspected SAH, traditional diagnostic strategies in the emergency department employ non-contrast computed tomography (CT) of the brain to detect blood in the subarachnoid space followed by lumbar puncture if there is a high clinical probability of aneurysmal bleed without any evidence of blood on CT scan. While the older generation CT scanners were less sensitive to blood detection in the subarachnoid space, recent advances in CT imaging have resulted in sensitivity approaching 100% for detection of blood in the subarachnoid space specifically within six hours of symptom onset. Therefore, the benefit of lumbar puncture is controversial when performed within the first six hours of symptom onset. Despite this, lumbar puncture is still commonly performed in the emergency department, exposing patients to unnecessary procedural risks. The objective of this research study is to develop a web-based risk calculator that estimates the risk of SAH based on time to emergency department presentation after symptom onset, physical findings and imaging characteristics with the goal of reducing unnecessary lumbar punctures in the emergency department. In this technical report, we describe the prototype calculator, the mathematical basis of the model and provide a link to the web-based prototype. In the future, we will refine the prototype, make it user-friendly to physicians, staff and patients and study its benefits in the emergency department. PMID- 29568718 TI - Sleep and Speech Outcomes After Superior Adenoidectomy in Children with Cleft Palate. AB - Objective To describe the sleep and speech outcomes in patients with cleft palate who underwent superior adenoidectomy. Subjectives and methods This is a case series with chart review of patients with diagnoses of cleft palate and sleep disordered breathing (SDB), obstructive sleep apnea (OSA) or nasal obstruction treated with superior adenoidectomy from 1991-2015 at the Children's Hospital of Minnesota. Postoperative clinic notes documented the changes in symptoms following surgery. All speech outcomes were recorded. Results Fifty patients (23 females, 27 males) aged 11 months to 17 years were included. Forty-six patients (92%) had improvement of sleep symptoms including snoring, nighttime restlessness, and witnessed apnea events, following superior adenoidectomy. Forty two of the 46 patients (91%) had stable speech postoperatively with either no development or no worsening of velopharyngeal insufficiency (VPI). Conclusion Superior adenoidectomy is an effective procedure to alleviate symptoms of sleep disordered breathing in patients with cleft palate without significantly affecting speech. PMID- 29568719 TI - Wind-Driven Erosion and Exposure Potential at Mars 2020 Rover Candidate-Landing Sites. AB - Aeolian processes have likely been the predominant geomorphic agent for most of Mars' history and have the potential to produce relatively young exposure ages for geologic units. Thus, identifying local evidence for aeolian erosion is highly relevant to the selection of landing sites for future missions, such as the Mars 2020 Rover mission that aims to explore astrobiologically relevant ancient environments. Here we investigate wind-driven activity at eight Mars 2020 candidate-landing sites to constrain erosion potential at these locations. To demonstrate our methods, we found that contemporary dune-derived abrasion rates were in agreement with rover-derived exhumation rates at Gale crater and could be employed elsewhere. The Holden crater candidate site was interpreted to have low contemporary erosion rates, based on the presence of a thick sand coverage of static ripples. Active ripples at the Eberswalde and southwest Melas sites may account for local erosion and the dearth of small craters. Moderate-flux regional dunes near Mawrth Vallis were deemed unrepresentative of the candidate site, which is interpreted to currently be experiencing low levels of erosion. The Nili Fossae site displayed the most unambiguous evidence for local sand transport and erosion, likely yielding relatively young exposure ages. The downselected Jezero crater and northeast Syrtis sites had high-flux neighboring dunes and exhibited substantial evidence for sediment pathways across their ellipses. Both sites had relatively high estimated abrasion rates, which would yield young exposure ages. The downselected Columbia Hills site lacked evidence for sand movement, and contemporary local erosion rates are estimated to be relatively low. PMID- 29568720 TI - Emerging pollutants in the EU: 10 years of NORMAN in support of environmental policies and regulations. AB - In 2005, the European Commission funded the NORMAN project to promote a permanent network of reference laboratories and research centers, including academia, industry, standardization bodies, and NGOs. Since then, NORMAN has (i) facilitated a more rapid and wide-scope exchange of data on the occurrence and effects of contaminants of emerging concern (CECs), (ii) improved data quality and comparability via validation and harmonization of common sampling and measurement methods (chemical and biological), (iii) provided more transparent information and monitoring data on CECs, and (iv) established an independent and competent forum for the technical/scientific debate on issues related to emerging substances. NORMAN plays a significant role as an independent organization at the interface between science and policy, with the advantage of speaking to the European Commission and other public institutions with the "bigger voice" of more than 70 members from 20 countries. This article provides a summary of the first 10 years of the NORMAN network. It takes stock of the work done so far and outlines NORMAN's vision for a Europe-wide collaboration on CECs and sustainable links from research to policy-making. It contains an overview of the state of play in prioritizing and monitoring emerging substances with reference to several innovative technologies and monitoring approaches. It provides the point of view of the NORMAN network on a burning issue-the regulation of CECs-and presents the positions of various stakeholders in the field (DG ENV, EEA, ECHA, and national agencies) who participated in the NORMAN workshop in October 2016. The main messages and conclusions from the round table discussions are briefly presented. PMID- 29568721 TI - Monoamine Oxidase A in Antisocial Personality Disorder and Borderline Personality Disorder. AB - Purpose of Review: Variation in the monoamine oxidase A (MAO-A) gene and MAO-A enzyme levels have been linked to antisocial behavior and aggression in clinical and non-clinical populations. Here, we provide an overview of the genetic, epigenetic, and neuroimaging research that has examined MAO-A structure and function in antisocial personality disorder (ASPD) and borderline personality disorder (BPD). Recent Findings: The low-activity MAO-A variable nucleotide tandem repeat genetic polymorphism has shown a robust association with large samples of violent and seriously violent offenders, many of whom had ASPD. A recent positron emission tomography (PET) study of ASPD similarly revealed low MAO-A density in brain regions thought to contribute to the psychopathology of the condition. By contrast, PET has also demonstrated that brain MAO-A levels are increased in BPD and that they relate to symptoms of low mood and suicidality. Summary: Candidate gene studies have produced the most compelling evidence connecting MAO-A genetic variants to both ASPD and BPD. Still, conflicting results abound in the literature, making it highly unlikely that ASPD or BPD is related to a specific MAO-A genetic variant. Future research should strive to examine how MAO-A genotypes interact with broad-spectrum environmental influences to produce brain endophenotypes that may ultimately become tractable targets for novel treatment strategies. PMID- 29568722 TI - Universal behaviour of high-Q Fano resonances in metamaterials: terahertz to near infrared regime. AB - The observation of Fano resonance phenomena is universal across several branches of physics. Photonics is one of the most important areas of physics that mainly deals with the control of light propagation and localization through its interaction with natural and artificially engineered media. In an era of miniaturization, manipulation of light at micro-nanoscales has assumed unprecedented significance due to its potential to satisfy the mankind with disruptive future technologies. In this work, we present our study on the universality of high quality factor Fano resonances in planar metamaterials across terahertz and infrared parts of the electromagnetic spectrum. The narrow linewidth asymmetric Fano resonant metamaterials have tremendous potential to find applications in micro-nanoscale flat lasers, sensors, and ultra-resolution spectrometers.

AB - We develop an algorithm for feature extraction based on structural similarity and demonstrate its application for atom and pattern finding in high-resolution electron and scanning probe microscopy images. The use of the combined local identifiers formed from an image subset and appended Fourier, or other transform, allows tuning selectivity to specific patterns based on the nature of the recognition task. The proposed algorithm is implemented in Pycroscopy, a community-driven scientific data analysis package, and is accessible through an interactive Jupyter notebook available on GitHub. PMID- 29568725 TI - Management of Septated Malignant Pleural Effusions. AB - Purpose of Review: We review recent studies of patients with septated malignant pleural effusions, to understand what the clinical implications for patients are and what evidence-based methods should be used to manage these effusions. Recent Findings: Fibrinolytics improve effusion size assessed radiologically in patients with a chest drain inserted for septated malignant pleural effusions but this does not translate into an improvement in breathlessness relief or pleurodesis success. Fibrinolytics have also been used in patients with septated effusions associated with indwelling pleural catheters, but dyspnoea relief has not been assessed in this population. Patients with septated effusions or extensive adhesions appear to have a worse prognosis. Summary: Patients with septated malignant pleural effusions have a poor prognosis and do not gain clinical benefit from fibrinolytics via chest drain. The role of fibrinolytics for septated effusions associated with indwelling pleural catheters requires further study. PMID- 29568726 TI - Promoting recovery from severe mental illness: Implications from research on metacognition and metacognitive reflection and insight therapy. AB - Research indicates that individuals with schizophrenia recover. Recovery, however means different things to different individuals and regardless of what kind of experiences define recovery, the individual diagnosed with the serious mental illness must feel ownership of their recovery. This raises the issue of how mental health services should systematically promote recovery. This paper explores the practical implications for research on metacognition in schizophrenia for this issue. First, we present the integrated model of metacognition, which defines metacognition as the spectrum of activities which allow individual to have available to themselves an integrated sense of self and others as they appraise and respond to the unique challenges they face. Second, we present research suggesting that many with schizophrenia experience deficits in metacognition and that those deficits compromise individuals' abilities to manage their lives and mental health challenges. Third, we discuss a form of psychotherapy inspired by this research, Metacognitive Reflection and Insight Therapy which assists individuals to recapture the ability to form integrated ideas about themselves and others and so direct their own recovery. The need for recovery oriented interventions to focus on process and on patient's purposes, assess metacognition and consider the intersubjective contexts in which this occurres is discussed. PMID- 29568727 TI - Complex posttraumatic stress disorder: The need to consolidate a distinct clinical syndrome or to reevaluate features of psychiatric disorders following interpersonal trauma? AB - Complex posttraumatic stress disorder (Complex PTSD) has been recently proposed as a distinct clinical entity in the WHO International Classification of Diseases, 11th version, due to be published, two decades after its first initiation. It is described as an enhanced version of the current definition of PTSD, with clinical features of PTSD plus three additional clusters of symptoms namely emotional dysregulation, negative self-cognitions and interpersonal hardship, thus resembling the clinical features commonly encountered in borderline personality disorder (BPD). Complex PTSD is related to complex trauma which is defined by its threatening and entrapping context, generally interpersonal in nature. In this manuscript, we review the current findings related to traumatic events predisposing the above-mentioned disorders as well as the biological correlates surrounding them, along with their clinical features. Furthermore, we suggest that besides the present distinct clinical diagnoses (PTSD; Complex PTSD; BPD), there is a cluster of these comorbid disorders, that follow a continuum of trauma and biological severity on a spectrum of common or similar clinical features and should be treated as such. More studies are needed to confirm or reject this hypothesis, particularly in clinical terms and how they correlate to clinical entities' biological background, endorsing a shift from the phenomenologically only classification of psychiatric disorders towards a more biologically validated classification. PMID- 29568728 TI - Repeatability of two-dimensional chemical shift imaging multivoxel proton magnetic resonance spectroscopy for measuring human cerebral choline-containing compounds. AB - AIM: To investigate the repeatability of proton magnetic resonance spectroscopy in the in vivo measurement of human cerebral levels of choline-containing compounds (Cho). METHODS: Two consecutive scans were carried out in six healthy resting subjects at a magnetic field strength of 1.5 T. On each occasion, neurospectroscopy data were collected from 64 voxels using the same 2D chemical shift imaging (CSI) sequence. The data were analyzed in the same way, using the same software, to obtain the values for each voxel of the ratio of Cho to creatine. The Wilcoxon related-samples signed-rank test, coefficient of variation (CV), repeatability coefficient (RC), and intraclass correlation coefficient (ICC) were used to assess the repeatability. RESULTS: The CV ranged from 2.75% to 33.99%, while the minimum RC was 5.68%. There was excellent reproducibility, as judged by significant ICC values, in 26 voxels. Just three voxels showed significant differences according to the Wilcoxon related-samples signed-rank test. CONCLUSION: It is therefore concluded that when CSI multivoxel proton neurospectroscopy is used to measure cerebral choline-containing compounds at 1.5 T, the reproducibility is highly acceptable. PMID- 29568729 TI - Audit of physical health monitoring in children and adolescents receiving antipsychotics in neurodevelopmental clinics in Northumberland. AB - AIM: To ascertain performance against the standards set by National Institute for Clinical Excellence (NICE) guidelines on physical health monitoring of thirty children and adolescents prescribed antipsychotics in neurodevelopmental clinics in Northumberland and identifying areas for improvement in practice. METHODS: The audit involved a review of recorded documentation pertaining to physical health monitoring in patient electronic records pertaining to children and adolescents attending neurodevelopmental clinics in Northumberland prescribed antipsychotics. Clients were also contacted by telephone if relevant documentation could not be identified or retrieved to confirm the details. 32 case notes were perused of which 2 were excluded as they had refused to have venepuncture which was documented in the electronic records. RESULTS: The overall audit results demonstrated partial compliance with NICE guidelines on physical health monitoring in children and adolescents prescribed antipsychotics. Bi-annual recording of height, weight, blood pressure, pulse rate and review of side effects was completed in 100% of subjects. However, annual monitoring for blood tests including liver function, renal function full blood count as well as biannual monitoring of serum prolactin, serum lipid profile was completed only in 56% of subjects. Comparative baseline characteristics between the two groups (compliant and non-compliant with guidelines) found no differences based on any socio-demographic or clinical variables. However, the proportion of patients in the group compliant to guidelines was higher in the age group of 12-17 years as compared to < 12 years (70.58% vs 38.46%), though not statistically significant (chi2 = 1.236; P = 0.24). CONCLUSION: Development of tailored and specific guidelines for physical health monitoring in children and adolescents prescribed antipsychotics taking into consideration clinical effectiveness and safety profile is likely to improve adherence rates. PMID- 29568730 TI - Factors associated with tobacco, alcohol, and other drug use among youth living in West Central Mexico. AB - AIM: To determine the prevalence of drug and substance abuse among high school students in Jalisco and its association with the severity of health, behavior and psychosocial problems in order to provide evidence for possible prevention and treatment needs. METHODS: A multi-stage random sample of Jalisco high school students was given a paper-and-pencil survey based upon an adapted version of the drug use screening inventory (DUSI) (n = 24699; n = 2832). The DUSI showed adequate psychometric characteristics in this population. The statistical analyses accommodated the complex survey design with attention to unequal probability of selection and clustering of participants within schools and regions. RESULTS: An estimated 44% of the students had smoked tobacco, one in five students was a current smoker, and one in four students used to smoke but had not smoked for one year or more. By contrast, 6.8% of the students reported having used marijuana, cocaine, or both. Behavioral problems, deviant peer affiliation, and troubled families were independently associated with drug use. One in two students who used tobacco or alcohol had used these drugs in the past year (46% and 54%, respectively), and one in four students who used marijuana or cocaine in their lifetime had used those drugs in the past year (28% in both cases). CONCLUSION: The rates of cocaine use as well as the proportion of current users were higher than expected among high school students and indicate changing patterns of drug use in Mexico. These results corroborate that the general trend of drug use by youth in Mexico is increasing. Results from this study help us better understand the needs of at-risk youth and the need for new treatment and prevention strategies. PMID- 29568731 TI - Bullying among people with visual impairment: Prevalence, associated factors and relationship to self-efficacy and life satisfaction. AB - AIM: To examine associated factors of bullying and to determine associations between bullying and psychosocial outcomes among individuals with visual impairments (VI). METHODS: We conducted an age-stratified cross-sectional survey of adults with VI who were recruited from the Norwegian Association of the Blind and Partially Sighted. Data were collected through structural telephone interviews in the period between February and May, 2017. Linear regression models were used to examine factors related to bullying and associations of bullying with self-efficacy and life satisfaction. RESULTS: A total of 736 individuals were interviewed. The lifetime and 6-mo prevalence of bullying was 41.7% and 8.2%, respectively. The majority of bullied participants reported VI-specific bullying (65.1%). Victimization of bullying was associated with young age, early onset-age of VI, and having other impairments. Participants who reported bullying had lower levels of self-efficacy [Adjusted relative risk (ARR): 0.40, 95% confidence interval (CI): 0.19-0.85] and life satisfaction (ARR: 0.68, 95%CI: 0.51-0.91). CONCLUSION: Bullying is highly prevalent among individuals with VI. Our findings suggest that interventions to reduce bullying may be beneficial for improving the well-being and life quality of people with VI. PMID- 29568732 TI - Role of Murine Complement Component C5 in Acute in Vivo Infection by Pathogenic Leptospira interrogans. AB - Leptospirosis is considered one of the most important zoonosis worldwide. The activation of the Complement System is important to control dissemination of several pathogens in the host. Only a few studies have employed murine models to investigate leptospiral infection and our aim in this work was to investigate the role of murine C5 during in vivo infection, comparing wild type C57BL/6 (B6 C5+/+) and congenic C57BL/6 (B6 C5-/-, C5 deficient) mice during the first days of infection. All animals from both groups survived for at least 8 days post infection with pathogenic Leptospira interrogans serovar Kennewicki strain Fromm (LPF). At the third day of infection, we observed greater numbers of LPF in the liver of B6 C5-/- mice when compared to B6 C5+/+ mice. Later, on the sixth day of infection, the LPF population fell to undetectable levels in the livers of both groups of mice. On the third day, the inflammatory score was higher in the liver of B6 C5+/+ mice than in B6 C5-/- mice, and returned to normal on the sixth day of infection in both groups. No significant histopathological differences were observed in the lung, kidney and spleen from both infected B6 C5+/+ than B6 C5-/- mice. Likewise, the total number of circulating leukocytes was not affected by the absence of C5. The liver levels of IL-10 on the sixth day of infection was lower in the absence of C5 when compared to wild type mice. No significant differences were observed in the levels of several inflammatory cytokines when B6 C5+/+ and B6 C5-/- were compared. In conclusion, C5 may contribute to the direct killing of LPF in the first days of infection in C57BL/6 mice. On the other hand, other effector immune mechanisms probably compensate Complement impairment since the mice survival was not affected by the absence of C5 and its activated fragments, at least in the early stage of this infection. PMID- 29568733 TI - New marine gastropod records for the Hellenic waters. AB - Background: The Hellenic Seas are influenced by on-going environmental changes and the introduction of alien species, which are expected to have an impact on their biodiversity. This study contributes to the knowledge of the Hellenic marine gastropod biodiversity, expanding data over the entire Greek territory, during the period from October 2008 to March 2017. Results: This work presents 45 species of gastropods not previously reported from Greece or reported only once, belonging to 19 families. From those species, one (Horologica sp.) is, most probably, an undescribed species, 17 are new for the Eastern Mediterranean Sea and 40 are new for the Hellenic fauna. Main taxonomic characteristics and ecological information such as habitat, distribution and origin, are given and discussed. Conclusions: By this report, the Hellenic gastropod biodiversity is enriched by 40 new records, out of which, 17 are new for the Eastern Mediterranean Sea, 4 are Lessepsian migrants previously reported for the Mediterranean Sea and 1 is probably a new species. PMID- 29568734 TI - FDG-PET/CT for diagnosis of cyst infection in autosomal dominant polycystic kidney disease. AB - Purpose: Cyst infections are a common complication in autosomal dominant polycystic kidney disease (ADPKD). Diagnosing these infections often remains challenging. Conventional imaging techniques such as ultrasonography, computed tomography (CT), and standard magnetic resonance imaging have several drawbacks and disadvantages. The purpose of this pictorial essay was to illustrate and discuss the potential value of 18F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET)/CT in diagnosing cyst infection in ADPKD. Methods: Exemplary (ADPKD) patients who underwent FDG-PET/CT as part of their routine clinical work up in our institution are presented to show the potential value and drawbacks of this imaging technique in diagnosing cyst infection. In addition, the current literature and guidelines on this topic were reviewed. Results: FDG-PET/CT appears to be a sensitive method for the detection of cyst infection, but it is not infallible. Furthermore, FDG uptake in cysts and cyst-like lesions is not specific and clinical and radiological correlations are essential to improve specificity and minimize the risk of falsely discarding other diseases, in particular malignancy. Conclusion: FDG-PET/CT seems to be a useful imaging modality to diagnose cyst infections in ADPKD. However, its exact diagnostic value has not been established yet due to the lack of a reliable reference standard in previous studies on this topic. PMID- 29568735 TI - Outcomes of a National Cohort of Children with Acute Severe Ulcerative Colitis. AB - Aim: All Irish children with ulcerative colitis (UC) attend the National Centre for Paediatric Gastroenterology at Our Lady's Children's Hospital, Crumlin. The aim of this study was to determine the outcomes of children with acute severe ulcerative colitis (ASC) and the impact of infliximab on these outcomes following its introduction for this indication in 2011. Methods: A retrospective chart review of all patients admitted with ASC between January 1, 2009 and December 31, 2015 was undertaken. Patients were identified from the departmental database cross-referenced with the hospital inpatient enquiry system. Inpatients with a paediatric ulcerative colitis activity index (PUCAI) of >=65 were included. Data collected included baseline demographic and laboratory data, concomitant treatments, PUCAI scores on days 3 and 5, second-line treatments, surgery, and discharge outcomes. Infliximab dose, frequency, and available therapeutic drug monitoring results were recorded, along with clinical response outcomes (remission, primary, and secondary loss of response). The cohort was sub-analysed to determine if there was any era effect pre- and post-introduction of infliximab (2009-2010 and 2011-2015, respectively). Results: Fifty-five patients (M:F = 1.4:1) were treated for acute severe colitis over the study period (8 in the pre infliximab and 47 in the post-infliximab era) and 46/55 (86%) had steroid refractory disease. Of these, 7/8 (88%) required colectomy in the pre-infliximab era, compared with 15/47 (36%) in the post-infliximab era. The remission rate with second-line infliximab was 61% at maximal follow-up. There were no identifiable factors that predicted likely success or failure of infliximab, including gender, CRP, day-3 and day-5 PUCAI scores. Of the 33 patients treated with infliximab, dose increase was required in 23/33 (70%); 21/33 (64%) received an accelerated dose schedule, and 9/33 (27%) eventually needed colectomy. Primary and secondary loss of response to infliximab was seen in one and nine patients, respectively. Conclusion: This is the first population-based study of the outcomes of severe UC in Irish children, and suggests a higher burden of steroid refractory disease compared with previous international studies. While infliximab treatment has led to reduction in colectomy rates, a significant proportion of patients lose therapeutic effect. PMID- 29568736 TI - A New Approach to Evaluating the Risk-Benefit Equation for Dual-Use and Gain-of Function Research of Concern. AB - In the twenty-first century, biology faces a problem that has previously vexed other disciplines such as physics, namely the prospect that its knowledge domain could be used to generate biological agents with altered properties that enhanced their weapon potential. Biological weapons bring the additional dimension that these could be self-replicating, easy to manufacture and synthesized with commonly available expertise. This resulted in increasing concern about the type of research done and communicated, despite the fact that such research often has direct societal benefits, bringing the dual-use dilemma to biology. The conundrum of dual use research of concern was crystallized by the so-called "gain-of function" type of experiments in which avian influenza viruses were endowed with new properties in the laboratory such as increased virulence and the capacity for mammalian transmission. After more than a decade of intensive discussion and controversy involving biological experiments with dual-use potential, there is no consensus on the issue except for the need to carry out such experiments in the safest conditions possible. In this essay, we review the topic with the hindsight of several years and suggest that instead of prescribing prohibitions and experimental limitations the focus should be on the importance of scientific questions at hand. We posit that the importance of a scientific question for medical and scientific progress provides a benchmark to determine the acceptable level of risk in biological experimentation.

AB - The computational modeling of peptide inhibitors to target protein-protein binding interfaces is growing in interest as these are often too large, too shallow, and too feature-less for conventional small molecule compounds. Here, we present a rare successful application of an alchemical binding free energy method for the calculation of converged absolute binding free energies of a series of protein-peptide complexes. Specifically, we report the binding free energies of a series of cyclic peptides derived from the LEDGF/p75 protein to the integrase receptor of the HIV1 virus. The simulations recapitulate the effect of mutations relative to the wild-type binding motif of LEDGF/p75, providing structural, energetic and dynamical interpretations of the observed trends. The equilibration and convergence of the calculations are carefully analyzed. Convergence is aided by the adoption of a single-decoupling alchemical approach with implicit solvation, which circumvents the convergence difficulties of conventional double decoupling protocols. We hereby present the single-decoupling methodology and critically evaluate its advantages and limitations. We also discuss some of the challenges and potential pitfalls of binding free energy calculations for complex molecular systems which have generally limited their applicability to the quantitative study of protein-peptide binding equilibria.

AB - Background: Cultural practices, beliefs, and taboos are often implicated in determining the care received by mothers during pregnancy and child birth which is an important determinant of maternal mortality. Objective: To assess prevalence of cultural malpractice during pregnancy, child birth, and postnatal period among women of childbearing age in Meshenti town, Amhara region, northwest Ethiopia, in 2016. Methods: Community based cross-sectional study was conducted among women of reproductive age group interviewed during the study period from May 10 to June 17, 2016. Total sample size was 318 women of reproductive age group. Systematic sampling technique was conducted. Result: Overall, 50.9% of the respondents had cultural malpractices during their pregnancy. Out of 318 women, 62 (19.5%) practiced nutrition taboo, 78 (24.5%) practiced abdominal massage, 87 (29.7%) delivered their babies at home, 96 (32.8%) avoided colostrums, 132 (45.2%) washed their baby before 24 hr after delivery, and 6 (6.9%) cut the cord by unclean blade. Conclusion and Recommendation: The findings of this study show that different traditional malpractice during perinatal period is still persisting in spite of modern developments in the world. Health education and promoting formal female education are important to decrease or avoid these cultural malpractices.

AB - This study introduced a combined computational fluid dynamics (CFD) and echocardiography methodology to simulate blood flow in the single right ventricle (SRV) and normal ventricles to study the intraventricular flow. Derived from echocardiographic image loops, CFD-based three-dimensional (3D) flow models of normal subject's left ventricle (LV) and right ventricle (RV) and SRV with and without heart failure at three characteristic diastolic statuses were reconstructed. The CFD derived morphological and functional measurements in normal ventricles and the SRV were validated with echocardiography. The vortex in the normal ventricles and the SRV were studied. The morphological and functional measurements derived from CFD modeling and echocardiography were comparable, and both methods demonstrated the larger volume and higher spherical index in the SRV, in particular the SRV with heart failure. All the vortices in the SRV were smaller than those in the normal control subject's LV and RV, notably with heart failure. Unlike normal LV and RV, no vortex ring was observed in the SRV. Echocardiography-based CFD demonstrated the feasibility of quantifying ventricular morphology and function; in addition, CFD can detect the abnormal flow pattern (smaller or obliterated vortices) in the SRV when compared with normal ventricles.

AB - L-Theanine is a nonprotein amino acid in tea, and its immunomodulatory function has been confirmed. This study aimed to investigate the effect of L-theanine addition on cytokines secretion in rat splenic lymphocytes and explore its potential immunomodulatory effects on the mevalonate biosynthetic pathway. Our results showed that L-theanine treatment did not influence the proliferation and division indexes of the splenic lymphocytes subsets. Interestingly, L-theanine treatment had regulated the contents of IFN-gamma, IL-2, IL-4, IL-10, IL-12, and TNF-alpha (P < 0.001) except IL-6 and upregulated the mRNA and protein expression of Ras-related protein Rap-1A (Rap1A), 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), and farnesyl diphosphate synthase (FDPs) (P < 0.001). Additionally, there was a positive correlation between Rap1A and HMGCR proteins expression and IFN-gamma, IL-4, and IL-6 levels. In conclusion, L-theanine regulated the secretion of cytokines probably by activating expression of Rap1A and HMGCR proteins involved in the mevalonate biosynthetic pathway in rat splenic lymphocytes. Therefore, L-theanine might be a promising potential drug candidate as immunopotentiator. PMID- 29568742 TI - Therapeutic Effect of Long-Term Epidural Block in Rats with Pregnancy Induced Hypertension. AB - Background: Pregnancy induced hypertension (PIH) causes a variety of systemic disorders that negatively affect the maternal placenta and fetal growth. Epidural sympathetic block elicits symptoms of decreased blood pressure. This study was designed to determine the therapeutic effect of long-term epidural block in rats with PIH. Methods: Forty healthy pregnant Sprague Dawley rats were randomized into four groups with each group consisting of 10 rats. On gestation day (GD) 14, rats in control group underwent a sham procedure; rats in RUPP group were operated on to obtain reduced uterine perfusion pressure (RUPP); rats in RUPP plus normal saline (NS) group were also subjected to the RUPP procedure and underwent epidural block with 25 MUl normal saline twice daily until delivery; rats in RUPP plus epidural block (EB) group were treated as those in RUPP plus NS group except that an epidural block with 25 MUl of 0.125% bupivacaine was administered two times per day until delivery. On GD 20, blood pressure was measured in all groups before delivery, and blood samples were collected in order to quantify the serum concentrations of vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase 1 (sFlt-1). Results: The mean arterial pressure (MAP) of rats in RUPP group (147.6 +/- 6.0 mmHg) was markedly increased when compared with control group (80.8 +/- 4.6 mmHg) (p < 0.05). The MAP of rats in RUPP plus EB group (114.4 +/- 7.2 mmHg) was clearly decreased in contrast with RUPP group but was still higher than in control group (p < 0.05). The variation of fetal weight in all groups followed a similar trend to that of MAP. However, there were no significant differences between control group and RUPP plus EB group with respect to placental weight (p = 0.186). Variation in MAP was positively correlated with the expression of sFlt-1 in each group but was negatively correlated with VEGF. Conclusion: This study demonstrates that long term epidural block decreases blood pressure in PIH rats and improves the serum concentrations of VEGF and sFlt-1. Taken together, long-term epidural block may have a potential role in PIH treatment. PMID- 29568743 TI - The Effects of Structured Physical Activity Program on Social Interaction and Communication for Children with Autism. AB - The purpose of this study was to investigate the effects of structured physical activity program on social interaction and communication of children with autism spectrum disorder (ASD). Fifty children with ASD from a special school were randomly divided into experimental and control groups. 25 children with ASD were placed in the experimental group, and the other 25 children as the control group participated in regular physical activity. A total of forty-one participants completed the study. A 12-week structured physical activity program was implemented with a total of 24 exercise sessions targeting social interaction and communication of children with ASD, and a quasi-experimental design was used for this study. Data were collected using quantitative and qualitative instruments. SSIS and ABLLS-R results showed that an overall improvement in social skills and social interaction for the experimental group across interim and posttests, F = 8.425, p = 0.001 (p < 0.005), and significant improvements appeared in communication, cooperation, social interaction, and self-control subdomains (p < 0.005). Conversely, no statistically significant differences were found in the control group (p > 0.005). The study concluded that the special structured physical activity program positively influenced social interaction and communication skills of children with ASD, especially in social skills, communication, prompt response, and frequency of expression. PMID- 29568744 TI - Fermentation Conditions and Media Optimization for Isocitric Acid Production from Ethanol by Yarrowia lipolytica. AB - Isocitric acid exists in the form of four stereoisomers, of which only the threo Ds-form (ICA) is a natural active compound, an intermediate of Krebs cycle, and suitable for nutritional and pharmaceutical use. In this paper, we propose a method for ICA production from ethanol by yeast Yarrowia lipolytica. The effects of temperature, pH of the medium, and aeration on the growth of the producer Y. lipolytica VKM Y-2373 and synthesis of ICA were studied. An optimal fermentation regime, which ensures a good growth of the producer and directed synthesis of the target product, was determined. The producer is advised to carry out cultivation at 29 degrees C and various pH of the medium and the oxygen concentration (pH 5 and pO2 20-25% (of saturation) during the growth period and pH 6 and pO2 50-55% (of saturation) during the acid formation) on a nutrient medium containing an increased content of zinc (0.6 mg/L), iron (1.2 mg/L), and 30 mM itaconic acid (inhibitor of isocitrate lyase-the key enzyme of ICA metabolism) should also be introduced into the nutrition medium. Such fermentation production mode provides 90.5 g/L ICA with process selectivity of 80%, mass yield (YICA) of 0.77 g/g, and energy yield (etaICA) of 0.278 g/g. PMID- 29568745 TI - Whole Peptidoglycan Extracts from the Lactobacillus paracasei subsp. paracasei M5 Strain Exert Anticancer Activity In Vitro. AB - The Lactobacillus paracasei subsp. paracasei M5 strain exerted potential anticancer activity through the cell wall. In this study, whole peptidoglycan (WPG) was extracted from the Lactobacillus paracasei subsp. paracasei M5 strain and was evaluated for anticancer effects as well as its properties. SDS-PAGE analysis confirmed the presence of WPG with dominant bands of approximately 14.4 kDa. Further analysis revealed that the amino acids present in the WPG consisted of alanine, glycine, glutamic acid, and lysine in a molar ratio of approximately 8 : 5 : 3 : 3.5. In addition, the cell viability of HT-29 cells with WPG addition was investigated with methyl thiazolyl tetrazolium (MTT) and trypan blue exclusion (TBE) assays, and cell apoptosis was analyzed with a transmission electron microscope, flow cytometry, and semiquantitative RT-PCR. These results showed that WPG exerted cytotoxic effects on colon cancer HT-29 cells in a dose dependent manner and upregulated proapoptotic genes, while downregulating antiapoptotic genes. The gene expression study definitively revealed that WPG induced a mitochondria-mediated apoptotic pathway. PMID- 29568746 TI - Metagenomics Biomarkers Selected for Prediction of Three Different Diseases in Chinese Population. AB - The dysbiosis of human microbiome has been proven to be associated with the development of many human diseases. Metagenome sequencing emerges as a powerful tool to investigate the effects of microbiome on diseases. Identification of human gut microbiome markers associated with abnormal phenotypes may facilitate feature selection for multiclass classification. Compared with binary classifiers, multiclass classification models deploy more complex discriminative patterns. Here, we developed a pipeline to address the challenging characterization of multilabel samples. In this study, a total of 300 biomarkers were selected from the microbiome of 806 Chinese individuals (383 controls, 170 with type 2 diabetes, 130 with rheumatoid arthritis, and 123 with liver cirrhosis), and then logistic regression prediction algorithm was applied to those markers as the model intrinsic features. The estimated model produced an F1 score of 0.9142, which was better than other popular classification methods, and an average receiver operating characteristic (ROC) of 0.9475 showed a significant correlation between these selected biomarkers from microbiome and corresponding phenotypes. The results from this study indicate that machine learning is a vital tool in data mining from microbiome in order to identify disease-related biomarkers, which may contribute to the application of microbiome-based precision medicine in the future. PMID- 29568747 TI - Targeted Next-Generation Sequencing of a Deafness Gene Panel (MiamiOtoGenes) Analysis in Families Unsuitable for Linkage Analysis. AB - Hearing loss (HL) is a common sensory disorder in humans with high genetic heterogeneity. To date, over 145 loci have been identified to cause nonsyndromic deafness. Furthermore, there are countless families unsuitable for the conventional linkage analysis. In the present study, we used a custom capture panel (MiamiOtoGenes) to target sequence 180 deafness-associated genes in 5 GJB2 negative deaf probands with autosomal recessive nonsyndromic HL from Iran. In these 5 families, we detected one reported and six novel mutations in 5 different deafness autosomal recessive (DFNB) genes (TRIOBP, LHFPL5, CDH23, PCDH15, and MYO7A). The custom capture panel in our study provided an efficient and comprehensive diagnosis for known deafness genes in small families. PMID- 29568748 TI - Long-Term Clinical Efficacy and Perioperative Safety of Endoscopic Submucosal Dissection versus Endoscopic Mucosal Resection for Early Gastric Cancer: An Updated Meta-Analysis. AB - Background: To systematically evaluate the safety and efficacy of endoscopic submucosal dissection (ESD) versus endoscopic mucosal resection (EMR) for early gastric cancer (EGC). Methods: We searched the databases of PubMed, Web of Science, EMBASE, and the Cochrane Library from January 2000 to April 2017 and included studies that compared the outcomes of ESD with EMR for EGC. These eligible studies that met the inclusion criteria were screened out and were assessed by two independent investigators. Result: In total, 18 retrospective cohort studies were eligible for analysis. Our results indicated that ESD is more beneficial than EMR in increasing the complete resection rate and en bloc resection rate and decreasing the local recurrence rate. However, ESD prolonged operative time and increased incidence of gastric perforation than EMR. No differences were found in postoperative bleeding rate between the two approaches. Conclusion: Compared with EMR, ESD offers higher complete resection rate, higher en bloc resection rate, and lower local recurrence rate but has prolonged operative time and increased incidence of gastric perfusion. There is no statistical difference in the rate of postoperative bleeding between the two groups. However, the above conclusion needs further verification by well designed, randomized trials with larger samples and long follow-up periods. PMID- 29568749 TI - Postactivation Potentiation Following Acute Bouts of Plyometric versus Heavy Resistance Exercise in Collegiate Soccer Players. AB - Postactivation potentiation is referred to as an acute and temporary enhancement of muscle performance resulting from previous muscle contraction. The purpose of this study was to compare the acute effect of plyometric exercise (PLY) and heavy resistance exercise (RES) on the blood lactate level (BLa) and physical performance. Fourteen male collegiate soccer players were randomized to perform either RES or PLY first and then crossed over to perform the opposite intervention. PLY consisted of 40 jumps, whereas RES comprised ten single repetitions at 90% of one repetition maximum. BLa and physical performance (countermovement jump height and 20-m sprint) were measured before and at 1 and 10 min following the exercise. No significant difference was observed in the BLa for both exercises (PLY and RES). Relative to baseline, countermovement jump (CMJ) height was significantly better for the PLY group after 1 min (P = 0.004) and after 10 min (P = 0.001) compared to that of the RES group. The 20-m sprint time was significantly better for PLY at 10 min (P = 0.003) compared to that of RES. The present study concluded that, compared to RES, PLY causes greater potentiation, which leads to improved physical performance. This trial is registered with NCT03150277. PMID- 29568750 TI - The Effect of Dexmedetomidine on Cognitive Function and Protein Expression of Abeta, p-Tau, and PSD95 after Extracorporeal Circulation Operation in Aged Rats. AB - Postoperative cognitive dysfunction (POCD) is a kind of serious neurologic complications and dexmedetomidine has a certain effect on POCD. However, functional mechanism of dexmedetomidine on POCD still remains unclear, so the research mainly studied the effect of dexmedetomidine on cognitive function and protein expression in hippocampus and prefrontal cortex cerebrospinal fluid after extracorporeal circulation operation in aged rats. We Found that, compared with POCD group, the cognitive function was improved in POCD + Dex group. We speculate that dexmedetomidine could improve the cognitive function after extracorporeal circulation operation in aged rats and Abeta, p-Tau, and PSD95 protein might have contributed to this favorable outcome. PMID- 29568752 TI - Propofol Reversed Hypoxia-Induced Docetaxel Resistance in Prostate Cancer Cells by Preventing Epithelial-Mesenchymal Transition by Inhibiting Hypoxia-Inducible Factor 1alpha. AB - Prostate cancer is the second most frequently diagnosed cancer worldwide. Hypoxia induced epithelial-mesenchymal transition (EMT), driven by hypoxia-inducible factor 1alpha (HIF-1alpha), is involved in cancer progression and metastasis. The present study was designed to explore the role of propofol in hypoxia-induced resistance of prostate cancer cells to docetaxel. We used the Cell Counting Kit-8 and 5-ethynyl-2'-deoxyuridine incorporation assay to measure cell viability and cell proliferation, respectively, in prostate cancer cell lines. Then, we detected HIF-1alpha, E-cadherin, and vimentin expression using western blotting. Propofol reversed the hypoxia-induced docetaxel resistance in the prostate cancer cell lines. Propofol not only decreased hypoxia-induced HIF-1alpha expression, but also reversed hypoxia-induced EMT by suppressing HIF-1alpha. Furthermore, small interfering RNA-mediated silencing of HIF-1alpha reversed the hypoxia induced docetaxel resistance, although there was little change in docetaxel sensitivity between the hypoxia group and propofol group. The induction of hypoxia did not affect E-cadherin and vimentin expression, and under the siRNA knockdown conditions, the effects of propofol were obviated. These data support a role for propofol in regulating EMT in prostate cancer cells. Taken together, our findings demonstrate that propofol plays an important role in hypoxia-induced docetaxel sensitivity and EMT in prostate cancer cells and that it is a potential drug for overcoming drug resistance in prostate cancer cells via HIF-1alpha suppression. PMID- 29568753 TI - Western Blot-Based Logistic Regression Model for the Identification of Recent HIV 1 Infection: A Promising HIV-1 Surveillance Approach for Resource-Limited Regions. AB - Objectives: Identifying recent infections is necessary to monitor HIV/AIDS epidemic; however, it needs to be further developed. Methods and Results: Participants were defined as having recent infection or older infection according to the estimated duration of HIV-1 infection and further assigned into training set and validation set according to their entering time points. Western blot (WB) confirmatory test and BED-CEIA were performed. The performance of the two methods on recent HIV-1 diagnosis was evaluated and compared. 81 subjects were enrolled in the training set and 72 in the validation set. Relative grey ratios of p24, p39, p31, p66, gp41, and gp160 were significantly higher in older infected patients of the training set. The present status of p55 was more frequently missing in recently infected patients in both sets. The logistic stepwise regression analysis of WB method shows sensitivity, specificity, and accuracy of 93.02%, 92.11%, and 92.59%. For BED-CEIA, they were 76.74%, 86.84%, and 81.48%. In the validation set, overall agreement rate, sensitivity, and specificity were 88.46%, 84.78%, and 86.11% in the WB-based method and 50.00%, 84.78%, and 72.22% in the BED-CEIA method. Conclusions: WB-based method is a promising approach to predict recent HIV-1 infection, especially in resource-limited regions.

AB - Polyphenols have been reported to have wide spectrum of biological activities including major impact on initiation, promotion, and progression of cancer by modulating different signalling pathways. Colorectal cancer is the second most major cause of mortality and morbidity among females and the third among males. The objective of this review is to describe the activity of a variety of polyphenols in colorectal cancer in clinical trials, preclinical studies, and primary research. The molecular mechanisms of major polyphenols related to their beneficial effects on colorectal cancer are also addressed. Synthetic modifications and other future directions towards exploiting of natural polyphenols against colorectal cancer are discussed in the last section. PMID- 29568754 TI - Monoamine Oxidase-A Inhibition and Associated Antioxidant Activity in Plant Extracts with Potential Antidepressant Actions. AB - Monoamine oxidase (MAO) catalyzes the oxidative deamination of amines and neurotransmitters and is involved in mood disorders, depression, oxidative stress, and adverse pharmacological reactions. This work studies the inhibition of human MAO-A by Hypericum perforatum, Peganum harmala, and Lepidium meyenii, which are reported to improve and affect mood and mental conditions. Subsequently, the antioxidant activity associated with the inhibition of MAO is determined in plant extracts for the first time. H. perforatum inhibited human MAO-A, and extracts from flowers gave the highest inhibition (IC50 of 63.6 MUg/mL). Plant extracts were analyzed by HPLC-DAD-MS and contained pseudohypericin, hypericin, hyperforin, adhyperforin, hyperfirin, and flavonoids. Hyperforin did not inhibit human MAO-A and hypericin was a poor inhibitor of this isoenzyme. Quercetin and flavonoids significantly contributed to MAO-A inhibition. P. harmala seed extracts highly inhibited MAO-A (IC50 of 49.9 MUg/L), being a thousand times more potent than H. perforatum extracts owing to its content of beta-carboline alkaloids (harmaline and harmine). L. meyenii root (maca) extracts did not inhibit MAO-A. These plants may exert protective actions related to antioxidant effects. Results in this work show that P. harmala and H. perforatum extracts exhibit antioxidant activity associated with the inhibition of MAO (i.e., lower production of H2O2). PMID- 29568756 TI - The Repair of Furcal Perforations in Different Diameters with Biodentine, MTA, and IRM Repair Materials: A Laboratory Study Using an E. Faecalis Leakage Model. AB - The aim of this study is to evaluate the microleakage of repair materials MTA, IRM, and Biodentine applied on furcal perforations with different diameters. One hundred and forty extracted human teeth were used in this study. The teeth were divided into 2 main groups (60 teeth in each) which were then divided into 3 subgroups (n = 20). The remaining 20 teeth were divided into 2 groups (10 in each) to serve as controls. The furcal areas of the teeth were perforated with #2 cylindrical burs in Group 1 whereas perforations were made using #4 cylindrical burs in Group 2. Each subgroup of both Groups 1 and 2 received ProRoot MTA (ProRoot, USA), Biodentine (Septodont), or IRM (Dentsply, USA) to repair the perforations. An experimental set-up was established to contaminate repaired perforations with E. Faecalis (ATCC29212). The turbidity of bacteria was observed on the 7th, 15th, 30th, and 45th days. The data was analysed by chi-square test (p > 0.05). The number of bacteria in the group perforated by bur #2 and closed by MTA was found to be lower than the other groups on the 7th day (p < 0.05). There was no statistical difference in the bacterial counts of other groups on the 15th, 30th, and 45th days (p > 0.05). ProRoot MTA was found to be more successful in the prevention of bacterial leakage compared to IRM and Biodentine in smaller perforations during the 1st week. PMID- 29568755 TI - Neuroaging through the Lens of the Resting State Networks. AB - Resting state functional magnetic resonance imaging (rs-fMRI) allows studying spontaneous brain activity in absence of task, recording changes of Blood Oxygenation Level Dependent (BOLD) signal. rs-fMRI enables identification of brain networks also called Resting State Networks (RSNs) including the most studied Default Mode Network (DMN). The simplicity and speed of execution make rs fMRI applicable in a variety of normal and pathological conditions. Since it does not require any task, rs-fMRI is particularly useful for protocols on patients, children, and elders, increasing participant's compliance and reducing intersubjective variability due to the task performance. rs-fMRI has shown high sensitivity in identification of RSNs modifications in several diseases also in absence of structural modifications. In this narrative review, we provide the state of the art of rs-fMRI studies about physiological and pathological aging processes. First, we introduce the background of resting state; then we review clinical findings provided by rs-fMRI in physiological aging, Mild Cognitive Impairment (MCI), Alzheimer Dementia (AD), and Late Life Depression (LLD). Finally, we suggest future directions in this field of research and its potential clinical applications. PMID- 29568757 TI - Remarks on Perfection in Plastic Surgery of the Face. AB - An expectation of perfect and close to ideal outcomes is attributed not only to aesthetic, but also to reconstructive surgery. Contrary to quite common belief and despite great potential, the real chances for achieving attractive appearance are limited to relatively simple cases with moderately abnormal morphology, sufficient homogenous material, and hardly conspicuous scars potential. Therefore, the expectations for fully satisfactory outcomes should be limited to jaw surgery, cosmetic rhinoplasty, otoplasty, and some rejuvenation procedures, provided the best and uneventful surgery is secured. On the basis of over 40 years of clinical practice (KK) and survey of about 30,000 photos presenting both early and long term outcomes, the authors present their own subjective opinion on the value and potential of plastic surgery with regard to aesthetic evaluation. The paper is illustrated by numerous examples of plastic and esthetic procedures.

Methods: Twelve consecutive patients of hepatocellular carcinoma, hepatic hemangioma, and focal nodular hyperplasia who received laparoscopic caudate lobectomy in Qilu Hospital of Shandong University from January 2013 to January 2017 were included in this study. The clinical data, intraoperative parameters, and postoperative outcomes were assessed. Results: All 12 patients received totally laparoscopic technique. The operative time was 140.8 +/- 95.34 minutes. The average estimated blood loss was 97.92 +/- 90.54 ml, and no blood transfusions were required. The mean duration of hospital stay was 9.17 +/- 2.88 days. There was no perioperative complication or patient mortality in this series. Conclusions: Laparoscopic caudate lobectomy is safe and feasible in the selected patients.

AB - The use of microbial technologies in agriculture is currently expanding quite rapidly with the identification of new bacterial strains, which are more effective in promoting plant growth. In the present study 18 strains of Pseudomonas were isolated from soil sample of Balochistan coastline. Among isolated Pseudomonas strains four designated as SP19, SP22, PS24, and SP25 exhibited biocontrol activities against phytopathogenic fungi, that is, Rhizopus microsporus, Fusarium oxysporum, Aspergillus niger, Alternaria alternata, and Penicillium digitatum; PS24 identified as Pseudomonas aeruginosa by 16srRNA gene bank accession number EU081518 was selected on the basis of its antifungal activity to explore its potential as plant growth promotion. PS24 showed multiple plant growth promoting attributes such as phosphate solubilization activity, indole acetic acid (IAA), siderophore, and HCN production. In order to determine the basis for antifungal properties, antibiotics were extracted from King B broth of PS24 and analyzed by TLC. Pyrrolnitrin antibiotic was detected in the culture of strain PS24. PS24 exhibited antifungal activities found to be positive for hydrogen cyanide synthase Hcn BC gene. Sequencing of gene of Hcn BC gene of strain PS24 revealed 99% homology with the Pseudomonas aeruginosa strain PA01. The sequence of PS24 had been submitted in gene bank accession number KR605499. Ps. aeruginosa PS24 with its multifunctional biocontrol possessions can be used to bioprotect the crop plants from phytopathogens. PMID- 29568760 TI - Citrus limon from Tunisia: Phytochemical and Physicochemical Properties and Biological Activities. AB - Natural plant extracts contain a variety of phenolic compounds which are assigned various biological activities. Our work aims to make a quantitative and qualitative characterization of the Zest (ZL) and the Flesh (FL) of lemon (Citrus limon), to valorize the pharmacological uses of lemon, by evaluating in vitro activities (DPPH, free radical scavenging and reducing power). The antibacterial, antifungal, and antiproliferative activities were sought in the ability of Citrus limon extracts to protect DNA and protein. We found that the ZL contains high amounts of phenolics responsible for the important antioxidant properties of the extract. However, the FL is richer in flavonoids than the ZL. The FL extract was also found to be more effective than the ZL in protecting plasmid DNA against the strand breakage induced by hydroxyl radicals. We also concluded that the FL extract exhibited potent antibacterial activity unlike ZL. Analysis by LC/MS-MS identified 6 compounds (Caffeoyl N-Tryptophan, Hydroxycinnamoyl-Oglucoside acid, Vicenin 2, Eriocitrin, Kaempferol-3-O- rutinoside, and Quercetin-3-rutinoside). These preliminary results showed that Citrus limon has antibacterial and antioxidant activity in vitro. It would be interesting to conduct further studies to evaluate the in vivo potential in an animal model. PMID- 29568761 TI - Glycyrrhizin Suppresses the Growth of Human NSCLC Cell Line HCC827 by Downregulating HMGB1 Level. AB - Lung cancer has very high mortality and glycyrrhizin was found to significantly inhibit the growth of lung cancer cells in vitro and tissues in mice. However, the detailed inhibitory role of glycyrrhizin in the growth of lung cancer is still unclear. In this study, we first found that glycyrrhizin inhibited the growth of lung tumor in PDX mice. And high level of HMGB1 promoted the migration and invasion of lung cancer cells, which was suppressed by glycyrrhizin. Moreover, glycyrrhizin reduced the activity of JAK/STAT signaling pathway, which is the upstream regulator of HMGB1. Therefore, this study revealed a potential mechanism by which glycyrrhizin can inhibit the progression of lung cancer. PMID- 29568762 TI - Compromised Dynamic Cerebral Autoregulation in Patients with Epilepsy. AB - Objective: The aim of this study is to analyze dynamic cerebral autoregulation (dCA) in patients with epilepsy. Methods: One hundred patients with epilepsy and 100 age- and sex-matched healthy controls were recruited. Noninvasive continuous cerebral blood flow velocity of the bilateral middle artery and arterial blood pressure were recorded. Transfer function analyses were used to analyze the autoregulatory parameters (phase difference and gain). Results: The overall phase difference of patients with epilepsy was significantly lower than that of the healthy control group (p = 0.046). Furthermore, patients with interictal slow wave had significant lower phase difference than the slow-wave-free patients (p = 0.012). There was no difference in overall phase between focal discharges and multifocal discharges in patients with epilepsy. Simultaneously, there was no difference in mean phase between the affected and unaffected hemispheres in patients with unilateral discharges. In particular, interictal slow wave was an independent factor that influenced phase difference in patients with epilepsy (p = 0.016). Conclusions: Our study documented that dCA is impaired in patients with epilepsy, especially in those with interictal slow wave. The impairment of dCA occurs irrespective of the discharge location and type. Interictal slow wave is an independent factor to predict impaired dCA in patients with epilepsy. Clinical Trial Identifier: This trial is registered with NCT02775682.

AB - Purpose: Comparative evaluation of morphological features of anterior capsules and apoptosis induction in epithelial cells after femtosecond laser-assisted cataract surgery (FLACS) and standard phacoemulsification surgery. Methods: Group 1: 30 FLACS anterior capsulotomies and Group 2: 30 manual anterior continuous curvilinear capsulorhexes. All patients were operated on by the same experienced surgeon. Morphological features of the anterior capsules and apoptosis induction in epithelial cells were evaluated. Results: All patients revealed a significant mean best-corrected visual acuity (BCVA) improvement 3 months after surgery, and no major intraoperative nor postoperative complications occurred. The capsular epithelium appeared to be preserved in both groups. Scanning electron microscopy analysis revealed irregular saw-tooth shaped edges in capsules from Group 1 whereas capsules from Group 2 showed regular and smooth edges. A statistically significant higher expression of the downstream apoptotic effector cleaved caspase 3 was observed in Group 1. Conclusions: The saw-tooth appearance was likely due to the progressive sequence of laser pulses on the capsule. The low energy/high frequency properties of the laser pulse, combined with an overlapped pulse pattern, resulted in highly continuous morphology of capsule edges. The higher apoptosis induction in FLACS group might be due to photodisruption dependent plasma generation and formation of cavitation bubbles.

AB - Elevated serum uric acid (SUA) level is known to be a prognostic factor in patients with acute coronary syndrome (ACS). However, the correlation between SUA level and coronary plaque instability has not been fully evaluated. The aim of this study was to investigate the association between SUA level and plaque instability of nonculprit lesions in patients with ACS using optical coherence tomography. A total of 150 patients with ACS who underwent 3-vessel optical coherence tomography were selected. Patients were classified into 3 groups according to tertiles of SUA level. There was a trend towards a thinner fibrous cap (0.15 +/- 0.06 versus 0.07 +/- 0.01 versus 0.04 +/- 0.01 mm2, p < 0.001) and a wider mean lipid arc (169.41 +/- 33.16 versus 177.22 +/- 37.76 versus 222.43 +/ 47.65 degrees , p < 0.001) with increasing SUA tertile. The plaques of the high and intermediate tertile groups had a smaller minimum lumen area than the low tertile group (6.02 +/- 1.11 versus 5.38 +/- 1.28 mm2, p < 0.001). In addition, thin-cap fibroatheromas, microvessels, macrophages, and cholesterol crystals were more frequent in the high tertile group than the low and intermediate groups. Multivariate analysis showed SUA level to be a predictor of plaque instability.

AB - Objective: We investigated the suitability of intraoral-scan models for measuring tooth dimensions and the amount of crowding in patients with severe tooth crowding. Materials and Methods: Fifty-eight patients who had undergone intraoral scans for diagnosis were included. Cast models were divided into two groups depending on the amount of crowding, as determined by initial caliper-based measurements (mild crowding [MC] group: <3.0 mm; severe crowding [SC] group: >4.5 mm). Twenty maxillary models and 20 mandibular models were used in this study. For the three types of models (i.e., IS digital model, C cast model, and CS digital model), the reproducibility and the precision of linear measurements were evaluated. Results: We found that linear measurements made using digital calipers on a plaster model and on the relevant software were reproducible. There was no significant difference in most linear measurements between digital models and the C model. There were differences in the amount of crowding (p < .05), although these were not clinically significant. There was no relationship between the precision of crowding in the three types of models and the severity of crowding. Conclusions: Digital models can be used for measuring crowding in both mild and severe crowding cases. However, crowding measured by digital models tends to be lesser than that measured by cast models, and this should be considered during clinical application. PMID- 29568765 TI - The Potential Protective Effect of Curcumin on Amyloid-beta-42 Induced Cytotoxicity in HT-22 Cells. AB - Background: We aimed to investigate the effect and mechanism of curcumin (CUR) in Alzheimer's disease (AD). Methods: Mouse hippocampal neuronal cell line HT-22 was treated with Abeta1-42 and/or CUR, and then cell viability was evaluated by cell counting kit 8, Beclin-l level was detected using western blotting, and the formation of autophagosomes was observed by transmission electron microscopy (TEM). Furthermore, transcriptome sequencing and analysis were performed in cells with Abeta1-42 alone or Abeta1-42 + CUR. Results: Abeta1-42 treatment significantly inhibited cell viability compared with untreated cells (P < 0.01). After treatment for 48 h, CUR remarkably promoted cell viability compared with cell treated with Abeta1-42 alone (P < 0.01). Compared with cells treated with Abeta1-42 alone, the expression of Beclin-1 was slightly reduced in cells with combined treatment of Abeta1-42 with CUR (P < 0.05). Consistently, TEM results showed that CUR inhibited the formation of autophagosomes in cells treated with Abeta1-42. Furthermore, the protein-protein interaction network showed five key genes, including MYC, Cdh1, Acaca, Egr1, and CCnd1, likely involved in CUR effects. Conclusions: CUR might have a potential neuroprotective effect by promoting cell viability in AD, which might be associated with cell autophagy. Furthermore, MYC, Cdh1, and Acaca might be involved in the progression of AD. PMID- 29568768 TI - Experimental Nanopulse Ablation of Multiple Membrane Parasite on Ex Vivo Hydatid Cyst. AB - The impact of ultrashort nanopulse on cellular membrane is of biological significance and thus has been studied intensively. Different from cell study, this ex vivo study aims to investigate the biological effects of nanosecond pulsed electric field (nsPEF) on an independent multimembrane parasite, human hydatid cyst, to observe the unique influence of nanopulse on macromembrane structure, permeabilization, and biochemistry. The 300 ns nsPEF was delivered on an experimental model of single human hydatid cyst ex vivo with eight different parameters. Then pathological changes during 7 days of 48 parasite cysts were followed up after nsPEF. The laminated layer, the germinal layer, the protoscolex, and cyst fluid were evaluated by the morphological, pathological, and biochemical measurements. The parameter screening found that nsPEF can damage hydatid cyst effectively when the field strength is higher than 14 kV/cm. When nsPEF is higher than 29 kV/cm, nsPEF destroy hydatid cyst completely by collapsing the germinal layer, destructing protoscolices, and exhausting the nutrition. PMID- 29568767 TI - Construction and Characterization of a Recombinant Human Respiratory Syncytial Virus Encoding Enhanced Green Fluorescence Protein for Antiviral Drug Screening Assay. AB - Human respiratory syncytial virus (RSV) is the single most important cause of lower respiratory tract disease in infants and young children and a major viral agent responsible for respiratory tract disease in immunosuppressed individuals and the elderly, but no vaccines and antiviral drugs are available. Herein the recombinant RSV (rRSV) encoding enhanced green fluorescence protein (EGFP, rRSV EGFP) was constructed and the potential for screening anti-RSV drugs was investigated. The recombinant plasmid of pBRATm-rRSV-EGFP, containing T7 transcription cassette composed of T7 promoter, RSV antigenomic cDNA with EGFP gene, HDV ribozyme (delta), and T7 terminator in the order of 5' to 3', was constructed and cotransfected into BHK/T7-9 cells together with helper plasmids encoding N, P, L, and M2-1 gene, respectively. The rescued rRSV-EGFP was confirmed by increasing expression of EGFP over blind passages and by RT-PCR. rRSV-EGFP was comparable to the other two recombinant RSVs encoding red fluorescent protein (RFP, rRSV-RFP) or luciferase (Luc, rRSV-Luc) in the growth kinetic, and there was a difference in sensitivity between them for screening anti-RSV agents based on infection of HEp-2 cells. The EGFP-encoding rRSV has been constructed and rescued successfully and has the potential for high throughput anti-RSV drug screening in vitro. PMID- 29568769 TI - Combination of Constraint-Induced Movement Therapy with Electroacupuncture Improves Functional Recovery following Neonatal Hypoxic-Ischemic Brain Injury in Rats. AB - Aim: Neonatal hypoxic-ischemia (HI) due to insufficient oxygen supply and blood flow during the prenatal and postnatal periods can cause cerebral palsy, a serious developmental condition. The purpose of this study was to investigate the efficacy of combining constraint-induced movement therapy (CIMT) and electroacupuncture to treat rat neonatal HI brain injury. Methods: The left common carotid arteries of postnatal day 7 rats were ligated to induce HI brain injury, and the neonates were kept in a hypoxia chamber containing 8% oxygen for 2 hrs. Electroacupuncture at Baihui (GV 20) and Zusanli (ST 36) was performed concurrently with CIMT 3 weeks after HI induction for 4 weeks. Results: Motor asymmetry after HI was significantly improved in the CIMT and electroacupuncture combination group, but HI lesion size was not improved. The combination of CIMT and electroacupuncture after HI injury increases NeuN and decreases GFAP levels in the cerebral cortex, suggesting that this combination treatment inversely regulates neurons and astrocytes. In addition, the combination treatment group reduced the level of cleaved caspase-3, a crucial mediator of apoptosis, in the cortex. Conclusions: Our findings indicate that a combination of CIMT and electroacupuncture is an effective method to treat hemiplegia due to neonatal HI brain injury. PMID- 29568770 TI - Stromal Cell-Derived Factor-1alpha Alleviates Calcium-Sensing Receptor Activation Mediated Ischemia/Reperfusion Injury by Inhibiting Caspase-3/Caspase-9-Induced Cell Apoptosis in Rat Free Flaps. AB - Surgical flaps are frequently affected by ischemia/reperfusion (I/R) injury. Calcium-sensing receptor (CaSR) and stromal cell-derived factor-1alpha (SDF 1alpha) are closely associated with myocardial I/R injury. This study was performed to evaluate the feasibility of applying SDF-1alpha to counteract CaSR activation-mediated I/R injury in ischemic free flaps. Free flaps that underwent ischemia for 3 h were equally randomized into five groups: CaCl2, NPS2143 + CaCl2, SDF-1alpha + CaCl2, AMD3100 + SDF-1alpha + CaCl2, and normal saline. The free flaps were harvested to evaluate flap necrosis and neovascularization after 2 h or 7 d of reperfusion. p-CaSR/CaSR was extensively expressed in vascular endothelial cells of free flaps after I/R injury, and activation of the SDF 1alpha/CXCR4 axis and NPS2143 could reduce the expression of cleaved caspase-3, caspase-9, FAS, Cyt-c, and Bax and increase Bcl-2 expression; the opposite was true after CaSR activation. Interestingly, initiation of the SDF-1alpha/CXCR4 axis might abrogate CaSR activation-induced I/R injury through enhancement of microvessel density. In conclusion, CaSR might become a novel therapeutic target of free flaps affected by I/R injury. Activation of the SDF-1alpha/CXCR4 axis and NPS2143 could counteract CaSR activation-mediated I/R injury and promote free flap survival through inhibition of caspase-3/caspase-9-related cell apoptosis and enhancement of neovascularization. PMID- 29568771 TI - Temporal Change of Interleukin-6, C-Reactive Protein, and Skin Temperature after Total Knee Arthroplasty Using Triclosan-Coated Sutures. AB - The risk of surgical site infections (SSIs) after total knee arthroplasty (TKA) can never be eliminated. Antimicrobial sutures containing triclosan have been used to decrease SSIs, but whether triclosan-coated sutures are effective with TKA is unclear. Between 2011 and 2012, 102 patients randomly assigned to a triclosan or a control group were prospectively assessed. The incidence of SSI within 3 months of surgery, length of hospital stay, pain scale, functional scores, wound condition, and serum inflammatory markers during hospitalization and within 3 months postoperatively were compared. At the final follow-up, there were 2 patients with superficial infections (3.9%) in the control group but none in the triclosan group. Lower serum IL-6 was detected in the triclosan group at 4 weeks and 3 months. The local skin temperature of the knees-recorded at 3 months using infrared thermography-was lower in the triclosan group than in the control group. More precise analytical measurements are needed to investigate local and systemic complications, especially in the early subclinical stage. This prospective, randomized, open-label clinical trial is in the public registry: ClinicalTrials.gov (NCT02533492). PMID- 29568772 TI - A Two-Step Feature Selection Method to Predict Cancerlectins by Multiview Features and Synthetic Minority Oversampling Technique. AB - Cancerlectins have an inhibitory effect on the growth of cancer cells and are currently being employed as therapeutic agents. The accurate identification of the cancerlectins should provide insight into the molecular mechanisms of cancers. In this study, a new computational method based on the RF (Random Forest) algorithm is proposed for further improving the performance of identifying cancerlectins. Hybrid feature space before feature selection is developed by combining different individual feature spaces, CTD (Composition, Transition, and Distribution), PseAAC (Pseudo Amino Acid Composition), PSSM (Position-Specific Scoring Matrix), and disorder. The SMOTE (Synthetic Minority Oversampling Technique) is applied to solve the imbalanced data problem. To reduce feature redundancy and computation complexity, we propose a two-step feature selection process to select informative features. A 5-fold cross validation technique is used for the evaluation of various prediction strategies. The proposed method achieves a sensitivity of 0.779, a specificity of 0.717, an accuracy of 0.748, and an MCC (Matthew's Correlation Coefficient) of 0.497. The prediction results are also compared with other existing methods on the same dataset using 5-fold cross-validation. The comparison results demonstrate the high effectiveness of our method for predicting cancerlectins. PMID- 29568773 TI - Does Psychosocial Work Environment Factors Predict Stress and Mean Arterial Pressure in the Malaysian Industry Workers? AB - Psychosocial risks are considered as a burning issue in the Asia-Pacific region. The aim of this study was to investigate the impact of psychosocial work environment factors on health of petrochemical industry workers of Malaysia. In lieu to job demands-resources theory, significant positive associations were found between quantitative demands, work-family conflict, and job insecurity with stress, while a significant negative association of role clarity as a resource factor with stress was detected. We also found that quantitative demands were significantly associated with the mean arterial pressure (MAP). Multistage sampling procedure was used to collect study sample. Structural Equation Modeling was used to identify relationship between the endogenous and exogenous variables. Finally, the empirically tested psychosocial work environment model will further help in providing a better risk assessment in different industries and enterprises. PMID- 29568774 TI - The Timed 180 degrees Turn Test for Assessing People with Hemiplegia from Chronic Stroke. AB - Background: Turning is ubiquitous in activities of daily living. For people with hemiplegia, persistent impairments in strength, balance, and coordination will affect their ability to turn safely. Consequently, turning retraining should be addressed in rehabilitation programs. To measure turning for these individuals, a reliable clinical tool is required. Objective: To investigate (i) the intrarater, interrater, and test-retest reliability of the timed 180 degrees turn test; (ii) the correlation of the timed 180 degrees turn test with other measures of stroke specific impairments; and (iii) the cut-off time that best discriminates individuals with hemiplegia from chronic stroke and healthy older adults. Methods: 33 individuals with hemiplegia due to chronic stroke and 32 healthy elderly individuals participated in this cross-sectional study. The timed 180 degrees turn test was administered along with other measures of stroke-specific impairment. Results: The timed 180 degrees turn test demonstrated excellent intrarater, interrater, and test-retest reliability in individuals with hemiplegia from chronic stroke. The timed 180 degrees turn test (times) significantly correlated with the Fugl-Meyer Assessment of the Lower Extremities (FMA-LE), affected ankle plantar flexion strength, the 5-Times-Sit-To-Stand test, the Berg Balance Scale (BBS), and the Timed Up and Go (TUG) test. Conclusion: The timed 180 degrees turn test is a reliable clinical tool to assess the turning ability of subjects with hemiplegia from chronic stroke. PMID- 29568775 TI - The Differential Expression of Core Genes in Nucleotide Excision Repair Pathway Indicates Colorectal Carcinogenesis and Prognosis. AB - Background: Nucleotide excision repair (NER) plays a critical role in maintaining genome integrity. This study aimed to investigate the expression of NER genes and their associations with colorectal cancer (CRC) development. Method: Expressions of NER genes in CRC and normal tissues were analysed by ONCOMINE. The Cancer Genome Atlas (TCGA) data were downloaded to explore relationship of NER expression with clinicopathological parameters and survival of CRC. Results: ERCC1, ERCC2, ERCC5, and DDB2 were upregulated while ERCC4 was downregulated in CRC. For colon cancer, high ERCC3 expression was related to better T stage; ERCC5 expression indicated deeper T stage and distant metastasis; DDB2 expression suggested earlier TNM stage. For rectal cancer, ERCC2 expression correlated with favourable T stage; XPA expression predicted worse TNM stage. ERCC2 expression was associated with worse overall survival (OS) in colon cancer (HR = 1.53, P = 0.043). Colon cancer patients with high ERCC4 expression showed favorable OS in males (HR = 0.54, P = 0.035). High XPC expression demonstrated decreased death hazards in rectal cancer (HR = 0.40, P = 0.026). Conclusion: ERCC1, ERCC2, ERCC4, ERCC5, and DDB2 were differently expressed in CRC and normal tissues; ERCC2, ERCC3, ERCC5, XPA, and DDB2 correlated with clinicopathological parameters of CRC, while ERCC2, ERCC4, and XPC might predict CRC prognosis. PMID- 29568776 TI - Physical Fitness, Grit, School Attendance, and Academic Performance among Adolescents. AB - Objective: The purpose of this study was to examine the relationship of grit as a construct representing perseverance to overcoming barriers and the total number of school absences to academic performance (AP) while controlling for sociodemographics, fitness (i.e., PACER), and Body Mass Index (BMI). Methods: Adolescents (N = 397, SD = 1.85; 80.9% females; 77.1% Hispanic) from an urban, minority-majority city in the Southern United States completed the FitnessGram(r) assessment of physical fitness (e.g., aerobic capacity and Body Mass Index (BMI)) and the valid and reliable short grit survey. The schools provided sociodemographics, attendance, and AP data for the adolescents. Results: Adolescents with higher grit scores (rs = 0.21, P < 0.001) and less total absences (rs = -0.35, P < 0.001) performed better on AP. Hierarchical multiple regression indicated that grit and absences were associated with AP (beta = 0.13, P < 0.01 and beta = -0.35, P < 0.001, resp.). Conclusions: Grit and a total number of absences are significant contributors to academic success, particularly among Hispanic adolescents. Further, grit and school attendance may serve as a better measure of protective factors over proximal health measures of cardiovascular health and BMI. PMID- 29568777 TI - Efficient FIR Filter Implementations for Multichannel BCIs Using Xilinx System Generator. AB - Background. Brain computer interface (BCI) is a combination of software and hardware communication protocols that allow brain to control external devices. Main purpose of BCI controlled external devices is to provide communication medium for disabled persons. Now these devices are considered as a new way to rehabilitate patients with impunities. There are certain potentials present in electroencephalogram (EEG) that correspond to specific event. Main issue is to detect such event related potentials online in such a low signal to noise ratio (SNR). In this paper we propose a method that will facilitate the concept of online processing by providing an efficient filtering implementation in a hardware friendly environment by switching to finite impulse response (FIR). Main focus of this research is to minimize latency and computational delay of preprocessing related to any BCI application. Four different finite impulse response (FIR) implementations along with large Laplacian filter are implemented in Xilinx System Generator. Efficiency of 25% is achieved in terms of reduced number of coefficients and multiplications which in turn reduce computational delays accordingly. PMID- 29568779 TI - Evaluating the Difference between Virtual and Paper-Based Clinical Cases in Family Medicine Undergraduate Education. AB - Introduction: A "virtual patient" is defined as a computer program which simulates real patients' cases. The aim of this study was to determine whether the inclusion of virtual patients affects the level of factual knowledge of family medicine students at the undergraduate level. Methods: This was a case controlled prospective study. The students were randomly divided into experimental (EG: N = 51) and control (CG: N = 48) groups. The students in the EG were asked to practice diagnosis using virtual patients instead of the paper based clinical cases which were solved by the students in the CG. The main observed variable in the study was knowledge of family medicine, determined by 50 multiple choice questions (MCQs) about knowledge of family medicine. Results: There were no statistically significant differences in the groups' initial knowledge. At the final assessment of knowledge, there were no statistically significant differences between the groups, but there was a statistically significant difference between their initial and final knowledge. Conclusions: The study showed that adding virtual patient cases to the curriculum, instead of paper clinical cases, did not affect the level of factual knowledge about family medicine. Virtual patients can be used, but a significant educational outcome is not expected. PMID- 29568778 TI - Integration of Routine Parameters of Glycemic Variability in a Simple Screening Method for Partial Remission in Children with Type 1 Diabetes. AB - Although different criteria were used to define partial remission in type 1 diabetes, the IDAA1C formula has prevailed as it correlates with stimulated C peptide levels. Our retrospective study evaluated clinical variables associated with the occurrence of IDAA1C-defined partial remission in a series of 239 pediatric patients. Diabetic ketoacidosis and age at diagnosis, but no other clinical feature, influenced the occurrence of remission. We then evaluated whether parameters of glycemic variability used in clinical routine may reliably define partial remission, as these would alleviate confounding factors related to insulin treatment. Using multiple linear regression, we observed that HbA1C levels and percentage of normoglycemia were efficient and sufficient to predict partial remission. These parameters were entered into a formula, called glycemic target-adjusted HbA1C (GTAA1C), that corresponded to HbA1C(%) - (3 * % of normoglycemic values(70-180 mg/dL)). With a threshold of 4.5, this alternative formula predicted partial remission with a sensitivity and a specificity of 72.3% and 92%, respectively, and yielded strong correlation with IDAA1C levels and BETA 2 score, which is a correlate of beta-cell function after islet transplantation. We propose GTAA1C, based on routine and objective markers of glycemic variability, as a valid alternative for definition of partial remission in type 1 diabetes. PMID- 29568780 TI - Drug-Induced Liver Injury: An Institutional Case Series and Review of Literature. AB - Drug-induced liver injury (DILI) is the most common cause of acute liver failure in the USA. DILI can be broadly classified as Intrinsic and Idiosyncratic. Identifying predictors and at-risk patients are challenging but can have a substantial clinical implication. This case report series demonstrates the importance of valproic acid, fluconazole, and amiodarone as potential hepatoxic agents of drug-induced liver injury leading to acute hepatic failure. The causality in all cases was established by Roussel Uclaf Causality Assessment Method/Council for International Organizations of Medical Sciences score and Naranjo Algorithm. Obesity, hypo-perfusion state, and concurrent hepatotoxic agent might identify at-risk patients. Further studies are required to understand the risk factors. PMID- 29568781 TI - Renal Artery Rupture in Association With Fibromuscular Dysplasia. AB - Fibromuscular dysplasia is a noninflammatory arteriopathy of unknown etiology that affects medium-sized arteries. Although patients affected with it are often asymptomatic, some might have recurrent catastrophic events that depend mainly on the arterial bed involved. The most worrisome vascular complications of the disease are aneurysmal rupture and arterial dissection. Herein, we report a case of a 49-year-old woman who presented with sudden-onset abdominal pain without any inciting factors. She was found to have active blood extravasation from a capsular branch of the renal artery that happened spontaneously. Angiography revealed fibromuscular dysplasia in the renal arteries without any obvious aneurysms. To our knowledge, this is the first case in the literature describing such an event. In this article, we also review the possible underlying pathology behind such an event. PMID- 29568782 TI - Proteinuria, Hypoalbuminemia, and Chronic Lymphocytic Leukemia: An Unusual Trio. AB - Chronic lymphocytic leukemia (CLL) is a chronic, progressive lymphoproliferative disorder characterized by a monoclonal population of functionally incompetent lymphocytes. Renal involvement is rare and poorly described. A 57-year-old male with no prior medical history was diagnosed with CLL and followed with a watch and wait approach. He was referred to our institution several months later due to concern for Richter's transformation to diffuse large B-cell lymphoma. A positron emission tomography/computed tomography scan showed no evidence of diffuse large B-cell lymphoma; however, the patient was noted to have hypoalbuminemia, nephrotic range proteinuria, an acute left renal vein thrombus, and a right pulmonary embolus. A nephrotic syndrome workup including autoimmunity and infection was unremarkable, and a kidney biopsy was deferred due to concern for renal compromise in the setting of a renal vein thrombus. The patient was treated with 6 cycles of reduced-dose fludarabine, cyclophosphamide, and rituximab for a presumed CLL-associated nephrotic syndrome and anticoagulation for his venous thromboemboli. At 6-month follow-up, the patient achieved complete remission of his CLL with normalization of all cell lines and resolution of his nephrotic range proteinuria. Repeat computed tomography scans showed no evidence of recurrent venous thromboemboli. This case demonstrates a potential role of empiric chemotherapy in cases of CLL-associated nephrotic syndrome given its potentially life-threatening sequelae and response to treatment. PMID- 29568783 TI - Kratom, an Emerging Drug of Abuse, Raises Prolactin and Causes Secondary Hypogonadism: Case Report. AB - Background. Kratom is a drug derived from the leaves of the tree Mitragyna speciose, which is native to southern Thailand. The route of administration is oral. Kratom has become increasingly available in the United States. The active ingredients in the drug bind the opioid mu-receptor; therefore, kratom has similar physiological effects as mu-opioids. Elevated prolactin is a common medical condition frequently caused by a variety drugs, including opioids. Case Report. A 42-year-old man presented with poor energy and low libido. He had mildly elevated serum prolactin with hypogonadotropic hypogonadism as evidenced by low serum testosterone with luteinizing hormone and follicle-stimulating hormone in the normal range. At his initial visit, he reported no use of any recreational or therapeutic drug. Two months later when seen in follow-up, both the testosterone and prolactin levels had returned to normal. At that visit he reported frequent use of kratom, which he had discontinued a few days after the first visit. Discussion. Kratom is now widely available in health food stores and online and is considered an emerging drug of abuse. At present kratom is legal in the United States, but recently the Drug Enforcement Administration served noticed of its intention of making kratom a Schedule I drug. A number of adverse events or side effects have been reported, but this is the first report of hyperprolactinemia as the result of ingestion of kratom. PMID- 29568784 TI - Does the Lever Sign Test Have Added Value for Diagnosing Anterior Cruciate Ligament Ruptures? AB - Background: Diagnosing an anterior cruciate ligament (ACL) rupture based on a physical examination remains a challenge for both surgeons and physical therapists. The lever sign test was developed to overcome the practical limitations of other tests and to optimize diagnosis. An evaluation of the measurement properties of the lever sign test is needed to make adequate interpretations in practice. Purpose: To evaluate the reliability and diagnostic value of the lever sign test. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 94 patients were recruited between November 2014 and July 2016. Patients were included if they were at least 16 years old, suffered from knee trauma, and had indications for knee arthroscopic surgery. Lever sign, anterior drawer, Lachman, and pivot-shift test outcomes were examined by an orthopaedic/trauma surgeon and a physical therapist. A test-retest design was used to investigate interrater reliability. Moreover, the lever sign test outcomes, alone and in combination with the other diagnostic tests, were compared with arthroscopic results, which served as the gold standard for the test's diagnostic value. Results: The lever sign test and pivot-shift test had kappa values exceeding 0.80 for interrater reliability. The kappa values for the anterior drawer test and Lachman test were 0.80 and 0.77, respectively. The lever sign test showed the highest specificity (100%) and the lowest sensitivity (39%) when compared with the other 3 tests. Moreover, its positive and negative predictive values were 100% and 65%, respectively, while an accuracy of 71% was calculated. Clustering the lever sign test parallel with the other 3 tests resulted in the highest accuracy of 91%. Conclusion: The lever sign test appears to have high interrater reliability and is the most specific test, showing a maximal positive predictive value. A positive lever sign test result indicates an ACL rupture. These results support the added value of the lever sign test for diagnosing ACL ruptures. PMID- 29568785 TI - Articular Cartilage Repair of the Knee in Children and Adolescents. AB - Articular cartilage predominantly serves a biomechanical function, which begins in utero and further develops during growth and locomotion. With regard to its 2 tissue structure (chondrocytes and matrix), the regenerative potential of hyaline cartilage defects is limited. Children and adolescents are increasingly suffering from articular cartilage and osteochondral deficiencies. Traumatic incidents often result in damage to the joint surfaces, while repetitive microtrauma may cause osteochondritis dissecans. When compared with their adult counterparts, children and adolescents have a greater capacity to regenerate articular cartilage defects. Even so, articular cartilage injuries in this age group may predispose them to premature osteoarthritis. Consequently, surgery is indicated in young patients when conservative measures fail. The operative techniques for articular cartilage injuries traditionally performed in adults may be performed in children, although an individualized approach must be tailored according to patient and defect characteristics. Clear guidelines for defect dimension associated techniques have not been reported. Knee joint dimensions must be considered and correlated with respect to the cartilage defect size. Particular attention must be given to the subchondral bone, which is frequently affected in children and adolescents. Articular cartilage repair techniques appear to be safe in this cohort of patients, and no differences in complication rates have been reported when compared with adult patients. Particularly, autologous chondrocyte implantation has good biological potential, especially for large-diameter joint surface defects. PMID- 29568786 TI - Reconsidering Return-to-Play Times: A Broader Perspective on Concussion Recovery. AB - Background: Return-to-play protocols describe stepwise, graduated recoveries for safe return from concussion; however, studies that comprehensively track return to-play time are expensive to administer and heavily sampled from elite male contact-sport athletes. Purpose: To retrospectively assess probable recovery time for collegiate patients to return to play after concussion, especially for understudied populations, such as women and nonelite athletes. Study Design: Cohort study; Level of evidence, 3. Methods: Medical staff at a military academy logged a total of 512 concussion medical records over 38 months. Of these, 414 records included complete return-to-play protocols with return-to-play time, sex, athletic status, cause, and other data. Results: Overall mean return to play was 29.4 days. Sex and athletic status both affected return-to-play time. Men showed significantly shorter return to play than women, taking 24.7 days (SEM, 1.5 days) versus 35.5 days (SEM, 2.7 days) (P < .001). Intercollegiate athletes also reported quicker return-to-play times than nonintercollegiate athletes: 25.4 days (SEM, 2.6 days) versus 34.7 days (SEM, 1.6 days) (P = .002). These variables did not significantly interact. Conclusion: Mean recovery time across all groups (29.4 days) showed considerably longer return to play than the most commonly cited concussion recovery time window (7-10 days) for collegiate athletes. Understudied groups, such as women and nonelite athletes, demonstrated notably longer recovery times. The diversity of this sample population was associated with longer return-to-play times; it is unclear how other population-specific factors may have contributed. These inclusive return-to-play windows may indicate longer recovery times outside the population of elite athletes. PMID- 29568787 TI - Sex-Based Differences in Knee Kinetics With Anterior Cruciate Ligament Strain on Cadaveric Impact Simulations. AB - Background: Females are at an increased risk of sustaining noncontact knee ligament injuries as compared with their male counterparts. The kinetics that load the anterior cruciate ligament (ACL) are still under dispute in the literature. Purpose/Hypothesis: The purpose of this study was to determine whether there are differences in knee kinetics between the sexes that lead to greater ACL strain in females when similar external loads are applied during a simulated drop vertical jump landing task. It was hypothesized that female limbs would demonstrate significant differences in knee abduction moment that predispose females to ACL injury when compared with males. Study Design: Controlled laboratory study. Methods: Motion analysis data of 67 athletes who performed a drop vertical jump were collected. The kinematic and kinetic data were used to categorize tertiles of relative risk, and these values were input into a cadaveric impact simulator to assess ligamentous loads during the simulated landing task. Uni- and multiaxial load cells and differential variable reluctance transducer strain sensors were utilized to collect kinetic data and maximum ACL strain for analysis. Conditions of external loads applied to the cadaveric limbs were systematically varied and randomized. Data were analyzed with 2-way repeated-measures analysis of variance and the Fisher exact test. Results: Five kinetic parameters were evaluated. Of the 5 kinetic variables, only knee abduction moment (KAM) demonstrated significant differences in females as compared with males (F1,136 = 4.398, P = .038). When normalized to height and weight, this difference between males and females increased in significance (F1,136 = 7.155, P = .008). Compared with males, females exhibited a 10.3-N.m increased knee abduction torque at 66 milliseconds postimpact and a 22.3-N.m increased abduction torque at 100 milliseconds postimpact. For loading condition, the condition of "maximum ACL strain" demonstrated a maximum difference of 54.3 N.m increased abduction torque and 74.5-N.m increased abduction torque at 66 milliseconds postimpact. Conclusion: Under the tested conditions, increased external loads led to increased medial knee translation force, knee abduction moment, and external knee moment. Females exhibited greater forces and moments at the knee, especially at KAM, when loaded in similar conditions. As these KAM loads are associated with increased load and strain on the ACL, the sex-based differences observed in the present study may account for a portion of the underlying mechanics that predispose females to ACL injury as compared with males in a controlled simulated athletic task. Clinical Relevance: KAM increases strain to the ACL under clinically representative loading. Additionally, this work establishes the biomechanical characteristics of knee loading between sexes. PMID- 29568788 TI - Barriers and Facilitators to Colorectal Cancer Screening Among Rural Women in Community Clinics by Heath Literacy. AB - Background: Rural women lag rural men and urban women in colon cancer (CRC) screening completion. Objective: To identify rural female patients' knowledge, beliefs barriers, self-efficacy, prior recommendation and completion of CRC screening using an FOBT and to compare these factors by health literacy (HL) level. Methods: This descriptive study was conducted between 2015 and 2016 in 4 rural community clinics in south Louisiana. Patients overdue for screening were given a structured interview by a research assistant. Results: 339 women were enrolled, mean age 58.5, 32% had limited HL, 66% were African American. Most (91.7%) had heard of CRC, yet only 71% knew of any CRC screening tests. Women with adequate HL had greater knowledge of specific tests than those with limited HL (78.4% vs 56.6%, p<0.001). Only 25.7% had been given information on CRC testing; those with adequate HL were more likely to have received information (30.1% vs 16.8%; p=0.017). Most women (93.2%) indicated they would want to know if they had CRC, while 72.2% reported a provider had recommended CRC screening. Only 24.9% said a healthcare provider had ever given them an FOBT or that they had ever completed an FOBT (22.7%). There were no differences in women's report of recommendation or completion by HL level.Self-efficacy for completing an FOBT was high; over 90% indicated they could get an FOBT, complete it and mail results to the lab. Level of confidence did not vary by literacy. Three of the four barrier items varied by HL with women with low HL being more likely to fear doing an FOBT because they thought FOBT instructions would be confusing (p=0.002), doing the test would be embarrassing (p=0.025) or messy (p=0.057). Conclusions: Rural women are receptive to CRC screening and view FOBTs as effective. Rural community clinics need to provide low cost FOBTs with literacy, gender and culturally appropriate information. PMID- 29568789 TI - Ending Cervical Cancer Screening in Low-Risk Women After Age 65: Understanding Barriers to Adherence With Evidence-Based Guidelines Among Primary Care Providers. AB - Background: Current evidence-based cervical cancer testing guidelines recommend that screening of low-risk women ceases after age 65. Despite this, research suggests that continued testing by primary care providers remains common and represents unnecessary patient discomfort, cost, and consumption of valuable primary care resources. Objective: To understand why primary care providers might knowingly ignore consensus evidence-based screening guidelines for cervical cancer in low-risk women of this age-group and to identify barriers to adherence with best practice recommendations. Methods: A survey tool to identify barriers to adherence with current guidelines for cervical cancer screening in low-risk women older than age 65 was mailed to 4929 randomly selected primary care providers throughout California. Providers were asked to indicate the predominant reason(s) they might knowingly continue cervical cancer screening in women older than 65 years, despite evidence-based recommendations to the contrary. Results: Qualified surveys were received from 1259 (25.5%) of those surveyed, representing primary care providers of all types, practicing in areas of vastly different demographics. Despite published reassurance to the contrary, many providers retain fear that discontinuation of testing in low-risk women after age 65 may result in missed invasive cervical cancer. Even among health-care providers who agree that cessation of screening is safe, other circumstances prompt their recommendation to continue cervical screening. Conclusion: Although the data from this study suggest areas of policy intervention to lessen unnecessary cervical cancer screening, the broader implication is that advancement of evidence-based medicine will be of little value in improving the quality and cost of health care if barriers to guideline adherence are poorly understood and addressed. PMID- 29568790 TI - Treatment Changes in General Practice Patients With Chronic Mental Disorders Following a Psychiatric-Psychosomatic Consultation. AB - Objective: To determine whether a psychiatric-psychosomatic consultation can identify unmet treatment needs and improve treatment of patients with mental disorders in general practice. Methods: In 40 primary care practices, 307 consecutive primary patients who met criteria for chronic mental disorders were assessed by a psychiatric-psychosomatic consultant. After random assignment, general practitioners (GPs) were informed for half of the patients about the results of the assessment and received recommendations on how to improve treatment. Changes in treatment and patient status were reevaluated after 6 months. Results: Patients were mostly having depression, adjustment, or anxiety disorders, with 28.8% on sick leave. Contact with their respective GPs was longer than a year in 77.2% of cases. Patients had already received pharmacotherapy (60.9%), psychotherapeutic counseling by GPs themselves (27.7%), psychotherapy by specialists (73.9%), psychiatric outpatient care (57%), inpatient psychiatric treatment (12.1%), inpatient psychosomatic rehabilitation (ie, specialized behavioral medicine facilities for patients with work problems; 41.4%), and a broad spectrum of other diagnostic and therapeutic measures. Newly recommended interventions included leisure activities (42%), a new specialist psychotherapy (37.5%), or inpatient psychosomatic treatment (15.3%). Most recommendations were agreed upon by the GP. Nevertheless, there was only a limited increase in therapeutic actions 6 months later, and no statistically significant improvement in the status of patients. Conclusion: General practitioners undertake a broad spectrum of therapeutic interventions in patients with chronic mental disorders. According to our results, additional psychiatric-psychosomatic consultations can intensify treatment but does not significantly change the general course of chronic mental disorders. PMID- 29568791 TI - Usefulness of Image Theater Workshops for Exploring Dilemmas in Diabetes Self Management Among Adolescents. AB - Diabetes treatment involves a demanding self-management regime that is particularly challenging to adolescents. There is a need for qualitative research into the specific contexts in which adolescents attempt to balance self management demands with the needs and desires of adolescent life. This study investigates the usefulness of image theater, a participatory form of theater using the body as an expressive tool, to articulate these dilemmas in daily life contexts. We performed a qualitative analysis of two image theater workshops with 12- to 18-year-old adolescents living with diabetes. Our results show three areas of application: (a) unraveling the contextual complexity of lived experience, (b) the articulation of implicit understandings and underlying motives, and (c) the playful exploration of new behavior. We conclude that image theater is a promising method, especially with respect to the opportunities of a more contextual and action-oriented understanding of the trade-offs made in self management provide for diabetes education and counseling. PMID- 29568792 TI - What Are the Perceptions, Experiences, and Behaviors of Health Care Providers After Implementation of a Comprehensive Smoke-Free Hospital Policy? AB - The aim of this study was to explore the perceptions, experiences, and behaviors of health care providers (HCPs) after the implementation of a comprehensive smoke free policy. This qualitative descriptive study, using semi-structured interviews, was conducted with 28 HCPs working in a Canadian hospital. Four overarching themes emerged from the analysis including (a) greater support for tobacco reduction, (b) enhanced patient care and interactions, (c) improved staff morale, and (d) some barriers still exist. The main findings suggest a comprehensive smoke-free hospital environment can strengthen the tobacco-free workplace culture within a hospital setting among HCPs where support for tobacco reduction is amplified, patient care and interactions regarding tobacco dependence are improved, and staff morale is enhanced. While there are still some challenging barriers as well as opportunities for improvements, the implementation of a comprehensive smoke-free policy heightened the call-to-action among HCPs to take a more active role in tobacco reduction. PMID- 29568793 TI - Experiences of Head and Neck Cancer Patients in Middle Adulthood: Consequences and Coping. AB - The head and neck cancer (HNC) rate is rising among the middle-aged adult population. This trend has been attributed primarily to human papillomavirus exposure. An HNC diagnosis and its complex treatments may trigger life-changing physical, emotional, and social consequences. An interpretive descriptive study was conducted to describe the experiences of a purposive sample of 10 middle-aged adults who had experienced HNC. Two main themes were identified: consequences of HNC and coping with HNC. Subthemes of consequences of HNC included: voicelessness; being or looking sick; shifts in family dynamics; and sexual practices, sexual feelings, and stigma. Subthemes of coping with HNC included seeking information, discovering inner strengths, relying on a support network, establishing a sense of normalcy, and finding meaning within the experience. Supportive nursing interventions were identified by considering results from the standpoint of King's theory of goal attainment. PMID- 29568794 TI - Impulsive, Disinhibited Behavior-Dining in a Restaurant. AB - Dining in a restaurant with a loved one who has dementia can be an ordeal, especially if the expectations of the caregiver do not match those of the patient and the restaurant environment is not suitable for patients with dementia. The size of the dining area, lighting, background music or noise, decor of the room, number of customers, variety of the items on the menu, number of plates and cutlery on the table, in addition to flowers, candles, and other decorations on the table are all potent distractors. There are so many stimuli; the patient can be overwhelmed with information overload and not able to focus on the main purpose of the event: have dinner and especially enjoy the other person's company. In this case scenario, we present a 62-year-old man diagnosed with behavioral variant frontotemporal dementia (bvFTD). His daughter "invited" him to have dinner with her at a very fancy restaurant to celebrate her promotion at work. Unfortunately, whereas the evening started very well, it had a catastrophic ending. We discuss what went wrong in the patient/daughter interaction and how the catastrophic ending could have been avoided or averted. PMID- 29568795 TI - Mediator Effect of Balance Problems on Association Between Grip Strength and Falls in Older Adults: Results From the KORA-Age Study. AB - Objective: To examine the association between grip strength and history of falls among older individuals, and to assess the possible mediating effect of balance problems on this relationship. Method: Data originate from KORA (Cooperative Health Research in the Region of Augsburg)-Age Study of 808 individuals (65 years and above). Follow-up assessment occurred 3 years later. Results: The risk of falls within the last 12 months was reduced on average by 3% (odds ratio [OR] 95% confidence interval [95% CI] = 0.97 [0.94, 0.99]; p value = .026) per 1-kg increase in maximum grip strength after adjusting for age and gender. There was a trend toward an indirect effect of grip strength through the mediator variable balance problems (p value = .043). Discussion: Increased muscular strength is associated with a reduced risk of falls in older age after adjustment for age and gender. The association is partially mediated by balance problems. Thus, in older adults, muscle-strengthening exercises may decrease the risk of falling. PMID- 29568796 TI - Desaturation During Cry in the Neonatal Period. PMID- 29568797 TI - Effects of consumption of whole grape powder on basal NF-kappaB signaling and inflammatory cytokine secretion in a mouse model of inflammation. AB - Dietary consumption of polyphenol-rich fruits, such as grapes, may reduce inflammation and potentially prevent diseases linked to inflammation. Here, we used a genetically engineered murine model to measure Nuclear Factor kappa-light chain-enhancer of activated B cells (NF-kappaB) activity and pro-inflammatory cytokine secretion to test the hypothesis that oral consumption of whole grape formulation reduces inflammatory signaling in the body. NF-kappaB luciferase reporter mice were divided into two groups, one which was fed an experimental diet formulated with 4% (w/w) whole grape powder (WGP) or another which was fed a control diet formulated with 3.6% glucose/fructose (w/w) combination. Simulated inflammation was induced in the mice by intraperitoneal injection of lipopolysaccharide (LPS). In vivo imaging was used to determine the effect of each diet on NF-kappaB activity. We found that there were no significant differences in weight gain between the WGP and control diet groups. However, there was a statistically significant (p<0.0001) difference in the progression of basal levels of NF-kappaB signaling between mice fed on control or WGP diet. There were no significant differences in NF-kappaB reporter indices between WGP- and control-diet groups after either acute or repeated inflammatory challenge. However, terminal blood collection revealed significantly (p<0.01) lower serum concentrations of the inflammatory cytokines Interleukin-6 (IL-6) and Tumor Necrosis Factor alpha (TNFalpha) only among WGP diet mice subjected to acute inflammatory challenge. Overall, these data suggest that while diets supplemented with WGP may suppress steady-state low levels of inflammatory signaling, such a supplementation may not alleviate exogenously induced massive NF-kappaB activation. PMID- 29568798 TI - Encoding of Spatial Attention by Primate Prefrontal Cortex Neuronal Ensembles. AB - Single neurons in the primate lateral prefrontal cortex (LPFC) encode information about the allocation of visual attention and the features of visual stimuli. However, how this compares to the performance of neuronal ensembles at encoding the same information is poorly understood. Here, we recorded the responses of neuronal ensembles in the LPFC of two macaque monkeys while they performed a task that required attending to one of two moving random dot patterns positioned in different hemifields and ignoring the other pattern. We found single units selective for the location of the attended stimulus as well as for its motion direction. To determine the coding of both variables in the population of recorded units, we used a linear classifier and progressively built neuronal ensembles by iteratively adding units according to their individual performance (best single units), or by iteratively adding units based on their contribution to the ensemble performance (best ensemble). For both methods, ensembles of relatively small sizes (n < 60) yielded substantially higher decoding performance relative to individual single units. However, the decoder reached similar performance using fewer neurons with the best ensemble building method compared with the best single units method. Our results indicate that neuronal ensembles within the LPFC encode more information about the attended spatial and nonspatial features of visual stimuli than individual neurons. They further suggest that efficient coding of attention can be achieved by relatively small neuronal ensembles characterized by a certain relationship between signal and noise correlation structures. PMID- 29568799 TI - Susceptibility to Oxidative Stress Is Determined by Genetic Background in Neuronal Cell Cultures. AB - Traumatic brain injury (TBI) leads to a deleterious and multifactorial secondary inflammatory response in the brain. Oxidative stress from the inflammation likely contributes to the brain damage although it is unclear to which extent. A largely unexplored approach is to consider phenotypic regulation of oxidative stress levels. Genetic polymorphism influences inflammation in the central nervous system and it is possible that the antioxidative response differs between phenotypes and affects the severity of the secondary injury. We therefore compared the antioxidative response in inbred rat strains dark agouti (DA) to piebald viral glaxo (PVG). DA has high susceptibility to inflammatory challenges and PVG is protected. Primary neuronal cell cultures were exposed to peroxynitrite (ONOO-), nitric oxide (NO), superoxide (O2-), and 4-hydroxynonenal (4-HNE). Our findings demonstrated a phenotypic control of the neuronal antioxidative response, specific to manganese O2- dismutase (MnSOD). DA neurons had increased levels of MnSOD, equal levels of peroxiredoxin 5 (PRDX5), decreased oxidative stress markers 3-nitrotyrosine (3-NT) and 4-HNE and decreased neuronal death detected by lactate dehydrogenase (LDH) release after 24 h, and higher oxidative stress levels by CellROX than PVG after 2 h. It is possible that DA neurons had a phenotypic adaptation to a fiercer inflammatory environment. ONOO- was confirmed as the most powerful oxidative damage mediator, while 4-HNE caused few oxidative effects. Inducible NO synthase (iNOS) was not induced, suggesting that inflammatory, while not oxidative stimulation was required. These findings indicate that phenotypic antioxidative regulation affects the secondary inflammation, which should be considered in future individualized treatments and when evaluating antioxidative pharmacological interventions. PMID- 29568800 TI - Metamorphic records of multiple seismic cycles during subduction. AB - Large earthquakes occur in rocks undergoing high-pressure/low-temperature metamorphism during subduction. Rhythmic major-element zoning in garnet is a common product of such metamorphism, and one that must record a fundamental subduction process. We argue that rhythmic major-element zoning in subduction zone garnets from the Franciscan Complex, California, developed in response to growth-dissolution cycles driven by pressure pulses. Using electron probe microanalysis and novel techniques in Raman and synchrotron Fourier transform infrared microspectroscopy, we demonstrate that at least four such pressure pulses, of magnitude 100-350 MPa, occurred over less than 300,000 years. These pressure magnitude and time scale constraints are most consistent with the garnet zoning having resulted from periodic overpressure development-dissipation cycles, related to pore-fluid pressure fluctuations linked to earthquake cycles. This study demonstrates that some metamorphic reactions can track individual earthquake cycles and thereby opens new avenues to the study of seismicity. PMID- 29568801 TI - Bats without borders: Predators learn novel prey cues from other predatory species. AB - Learning from others allows individuals to adapt rapidly to environmental change. Although conspecifics tend to be reliable models, heterospecifics with similar resource requirements may be suitable surrogates when conspecifics are few or unfamiliar with recent changes in resource availability. We tested whether Trachops cirrhosus, a gleaning bat that localizes prey using their mating calls, can learn about novel prey from conspecifics and the sympatric bat Lophostoma silvicolum. Specifically, we compared the rate for naive T. cirrhosus to learn an unfamiliar tone from either a trained conspecific or heterospecific alone through trial and error or through social facilitation. T. cirrhosus learned this novel cue from L. silvicolum as quickly as from conspecifics. This is the first demonstration of social learning of a novel acoustic cue in bats and suggests that heterospecific learning may occur in nature. We propose that auditory-based social learning may help bats learn about unfamiliar prey and facilitate their adaptive radiation. PMID- 29568802 TI - Evidence of Early Emergence of the Primary Dentition in a Northern Plains American Indian Population. AB - The purposes of this study were to describe primary tooth emergence in an American Indian (AI) population during the first 36 mo of life to compare 1) patterns of emergence between male and female children and 2) tooth emergence between these AI children and other U.S. ethnic groups. Data were derived from a birth cohort of 239 AI children from a Northern Plains tribe participating in a longitudinal study of early childhood caries, with examination data at target ages of 8, 12, 16, 22, 28, and 36 mo of age (+/-1 mo). Patterns of emergence in AI children were characterized and sex comparisons accomplished with interval censored survival methodology. Numbers of erupted teeth in AI children at each age were compared via Kruskal-Wallis tests against those in children of the same age, as drawn from a cross-sectional study of dental caries patterns in Arizona; these comparisons were based on the dental examinations of 547 White non-Hispanic and 677 Hispanic children. Characterization of time to achievement of various milestones-including emergence of the anterior teeth, the first molars, and the complete primary dentition-provided no evidence of sex differences among AI children. AI children had significantly more teeth present at 8 mo (median, 3) than either White non-Hispanic (P < 0.0063) or Hispanic (P < 0.0001) children (median, 2 each). This was also true at 12 mo (P < 0.001; medians, 8 vs. 6 and 7, respectively) and 16 mo (P < 0.001; medians, 12 vs. 11 each). Less pronounced differences were seen at 22 mo (P < 0.0001). White non-Hispanic and Hispanic children did not differ at any time considered (P > 0.05). These results provide evidence of earlier tooth emergence in AI children than in the other 2 ethnicities. Although the underlying etiology of the severity of early childhood caries in AI children is likely to be multifactorial, earlier tooth emergence may be a contributing factor. Knowledge Transfer Statement: The findings of this study have practical implications for practitioners providing childhood oral health care to ethnic groups with early tooth emergence. It may be important to provide parents with information on toothbrushing, dentist visits, and other practices supportive of good oral health as early as possible to protect their children's primary dentition. PMID- 29568803 TI - School-Based Caries Prevention, Tooth Decay, and the Community Environment. AB - The school and community context can contribute to inequity in child oral health. Whether the school and community affect the effectiveness of school-based caries prevention is unknown. The association between the school and community environment and dental caries, as well as their moderating effects with school based caries prevention, was assessed using multilevel mixed-effects regression. Data were derived from a 6-y prospective cohort study of children participating in a school-based caries prevention program. For the school and community, living in a dental-shortage area and the proportion of children receiving free or reduced lunch were significantly related to an increased risk of dental caries at baseline. Caries prevention was associated with a significant per-visit decrease in the risk of untreated caries, but the rate of total caries experience increased over time. Caries prevention was more effective in children who had prior dental care at baseline and in schools with a higher proportion of low socioeconomic status students. There was significant variation across schools in the baseline prevalence of dental caries and the effect of prevention over time, although effects were modest. The school and community environment have a direct impact on oral health and moderate the association between school-based caries prevention and dental caries. Knowledge Transfer Statement: School-based caries prevention can be an effective means to reduce oral health inequity by embedding dental care within schools. However, the socioeconomic makeup of schools and characteristics of the surrounding community can affect the impact of school based care. PMID- 29568804 TI - Screening for Diabetes Risk Using Integrated Dental and Medical Electronic Health Record Data. AB - Undiagnosed diabetes and prediabetes present a serious public health challenge. We previously reported that data available in the dental setting can serve as a tool for early dysglycemia identification in a primarily Hispanic, urban population. In the present study, we sought to determine how the identification approach can be recalibrated to detect diabetes or prediabetes in a White, rural cohort and whether an integrated dental-medical electronic health record (iEHR) offers further value to the process. We analyzed iEHR data from the Marshfield Clinic, a health system providing care in rural Wisconsin, for dental patients who were >=21 y of age, reported that they had never been told they had diabetes, had an initial periodontal examination of at least 2 quadrants, and had a glycemic assessment within 3 mo of that examination. We then assessed the performance of multiple predictive models for prediabetes/diabetes. The study outcome, glycemic status, was gleaned from the medical module of the iEHR based on American Diabetes Association blood test cutoffs. The sample size was 4,560 individuals. Multivariate logistic regression revealed that the best performance was achieved by a model that took advantage of the iEHR. Predictors included age, sex, race, ethnicity, number of missing teeth, percentage of teeth with at least 1 pocket >=5 mm from the dental EHR, and overweight/obesity, hypertension, hyperlipidemia, and smoking status from the medical EHR. The model achieved an area under the receiver operating characteristic curve of 0.71 (95% confidence interval, 0.69-0.72), yielding a sensitivity of 0.70 and a specificity of 0.62. Across a range of populations, informed by certain patient characteristics, dental care team members can play a role in helping to identify dental patients with undiagnosed diabetes or prediabetes. The accuracy of the prediction increases when dental findings are combined with information from the medical EHR. Knowledge Transfer Statement: Prediabetes and diabetes often go undiagnosed for many years. Early identification and care can lead to improved glycemic outcomes and prevent wide-ranging morbidity, including adverse oral health consequences, in affected individuals. Information available in the dental office can be used by clinicians to identify those who remain undiagnosed or are at risk; the accuracy of this prediction increases when combined with information from the medical electronic health record. PMID- 29568805 TI - Status and determinants of health services utilization among elderly migrants in China. AB - Background: The household registration system in China places migrants in a vulnerable status regarding access to local public services, including limited access to health services. Most studies on migrants' health services utilization targeted on working-age migrants, and there has been a paucity of studies conducted among elderly migrants. This study aims to investigate the status of health services utilization and its influential factors among elderly migrants. Methods: Data (13,043 participants, 52.4% male, mean age 66.22 +/- 6.20) were derived from the 2015 Migrant Dynamics Monitoring Survey. The outcome variable in the study was health services utilization, consisting of doctor visits, hospitalization and local inpatient care. The Behavioral Model of Health Service Use was applied to categorize the influential factors into three components, including predisposing, enabling and need factors. Multivariate logistic regression analysis was used to investigate the influential factors of the three components of health services utilization. Results: Of the total sample, 45.5% would visit a doctor when they were ill, 81.8% would prefer to be hospitalized when recommended by doctors, and 71.6% (those who were hospitalized) would choose to receive local inpatient care rather than going back to their hometown. Age, marital status, household income, years of residence, migration range, reasons for migration, size of friend network, health insurance type, local health insurance status and chronic disease status were significantly associated with health services utilization. Conclusion: A low level of local health services utilization was observed among elderly migrants. Enabling factors played important roles in promoting health services utilization among elderly migrants. Policy and decision makers may consider improving the capability for elderly migrants to access health services, such as increasing income and providing local health insurance. PMID- 29568806 TI - Antibiotic resistance patterns of urinary tract pathogens in Turkish children. AB - Background: Knowledge of local antimicrobial resistance patterns is essential for evidence- based empirical antibiotic prescribing. We aimed to investigate the distribution and changes in causative agents of urinary tract infections in children and the resistance rates, and to recommend the most appropriate antibiotics. Methods: In this retrospective study, we evaluated causative agents and antimicrobial resistance in urine isolates from the positive community from September 2014 to April 2016 in a single hospital in Ankara, Turkey. Results: A total of 850 positive urine cultures were identified, of which 588 (69.2%) were from girls and 262 (30.8%) were from boys. Their mean age was 36.5 +/- 45.0 months. The most common causative agent was Escherichia coli (64.2% of cases) followed by Klebsiella pneumoniae (14.9%). The overall resistance to ampicillin (62.6%), cephalothin (44.2%), co-trimoxazole (29.8%) and cefuroxime (28.7%) was significant. No resistance to imipenem was detected in the isolates. The least resistance was for amikacin, ceftriaxone, ciprofloxacin and cefepime (0.1, 2.4, 7.5 and 8.3%, respectively). Imipenem was the most active agent against E. coli followed by amikacin (0.2%), ceftriaxone (2.7%) and nitrofurantoin (5.1%). High resistance rates to nitrofurantoin were detected in K. pneumoniae, Proteus and Enterobacteriae. Conclusions: E. coli was the most common causative agent of urinary tract infection in children. Ampicillin, trimethoprim-sulfometaxazole, cephalothin and cefuroxim had the highest resistance rates against urinary tract pathogens in our center. For oral empirical antibiotherapy, cefixime is the most appropriate choice so as to include Klebsiella strains. PMID- 29568807 TI - The age of heterozygous telomerase mutant parents influences the adult phenotype of their offspring irrespective of genotype in zebrafish. AB - BACKGROUND: Mutations in proteins involved in telomere maintenance lead to a range of human diseases, including dyskeratosis congenita, idiopathic pulmonary fibrosis and cancer. Telomerase functions to add telomeric repeats back onto the ends of chromosomes, however non-canonical roles of components of telomerase have recently been suggested. METHODS: Here we use a zebrafish telomerase mutant which harbours a nonsense mutation in tert to investigate the adult phenotypes of fish derived from heterozygous parents of different ages. Furthermore we use whole genome sequencing data to estimate average telomere lengths. RESULTS: We show that homozygous offspring from older heterozygotes exhibit signs of body wasting at a younger age than those of younger parents, and that offspring of older heterozygous parents weigh less irrespective of genotype. We also demonstrate that tert homozygous mutant fish have a male sex bias, and that clutches from older parents also have a male sex bias in the heterozygous and wild-type populations. Telomere length analysis reveals that the telomeres of younger heterozygous parents are shorter than those of older heterozygous parents. CONCLUSIONS: These data indicate that the phenotypes observed in offspring from older parents cannot be explained by telomere length. Instead we propose that Tert functions outside of telomere length maintenance in an age-dependent manner to influence the adult phenotypes of the next generation. PMID- 29568808 TI - Small-scale field evaluation of push-pull system against early- and outdoor biting malaria mosquitoes in an area of high pyrethroid resistance in Tanzania. AB - Background: Despite high coverage of indoor interventions like insecticide treated nets, mosquito-borne infections persist, partly because of outdoor biting, early-biting and insecticide-resistant vectors. Push-pull systems, where mosquitoes are repelled from humans and attracted to nearby lethal targets, may constitute effective complementary interventions. Methods: A partially randomized cross-over design was used to test efficacy of push-pull in four experimental huts and four local houses, in an area with high pyrethroid resistance in Tanzania. The push-pull system consisted of 1.1% or 2.2% w/v transfluthrin repellent dispensers and an outdoor lure-and-kill device (odour-baited mosquito landing box). Matching controls were set up without push-pull. Adult male volunteers collected mosquitoes attempting to bite them outdoors, but collections were also done indoors using exit traps in experimental huts and by volunteers in the local houses. The collections were done hourly (1830hrs-0730hrs) and mosquito catches compared between push-pull and controls. An. gambiae s.l. and An. funestus s.l. were assessed by PCR to identify sibling species, and ELISA to detect Plasmodium falciparum and blood meal sources. Results: Push-pull in experimental huts reduced outdoor-biting for An. arabiensis and Mansonia species by 30% and 41.5% respectively. However, the reductions were marginal and insignificant for An. funestus (12.2%; p>0.05) and Culex (5%; p>0.05). Highest protection against all species occurred before 2200hrs. There was no significant difference in number of mosquitoes inside exit traps in huts with or without push pull. In local households, push-pull significantly reduced indoor and outdoor biting of An. arabiensis by 48% and 25% respectively, but had no effect on other species. Conclusion: This push-pull system offered modest protection against outdoor-biting An. arabiensis, without increasing indoor mosquito densities. Additional experimentation is required to assess how transfluthrin-based products affect mosquito blood-feeding and mortality in push-pull contexts. This approach, if optimised, could potentially complement existing malaria interventions even in areas with high pyrethroid resistance. PMID- 29568809 TI - Effects of engineered nanomaterial exposure on macrophage innate immune function. AB - Increasing use of engineered nanomaterials (ENMs) means increased human exposures. Potential adverse effects include those on the immune system, ranging from direct toxicity to impairment of defenses against environmental pathogens and toxins. Effects on lung macrophages may be especially prominent, because they serve to clear foreign materials like ENMs and bacterial pathogens. We investigated the effects of 4 hour exposures over a range of concentrations, of a panel of industry-relevant ENMs, including SiO2, Fe2O3, ZnO, CeO2, TiO2, and an Ag/SiO2 composite, on human THP-1 macrophages. Effects on phagocytosis of latex beads, and phagocytosis and killing of Francisella tularensis (FT), as well as viability, oxidative stress and mitochondrial integrity, were measured by automated scanning confocal microscopy and image analysis. Results revealed some notable patterns: 1) Phagocytosis of unopsonized beads was increased, whereas that of opsonized beads was decreased, by all ENMs, with the exception of ZnO, which reduced both opsonized and unopsonized uptake; 2) Uptake of opsonized and unopsonized FT was either impaired or unaffected by all ENMs, with the exception of CeO2, which increased phagocytosis of unopsonized FT; 3) Macrophage killing of FT tended to improve with all ENMs; and 4) Viability was unaffected immediately following exposures with all ENMs tested, but was significantly decreased 24 hours after exposures to Ag/SiO2 and ZnO ENMs. The results reveal a complex landscape of ENM effects on macrophage host defenses, including both enhanced and reduced capacities, and underscore the importance of robust hazard assessment, including immunotoxicity assessment, of ENMs. PMID- 29568810 TI - The Role of the Food Matrix and Gastrointestinal Tract in the assessment of biological properties of ingested engineered nanomaterials (iENMs): State of the science and knowledge gaps. AB - Many foods contain appreciable levels of engineered nanomaterials (ENMs) (diameter < 100 nm) that may be either intentionally or unintentionally added. These ENMs vary considerably in their compositions, dimensions, morphologies, physicochemical properties, and biological responses. From a toxicological point of view, it is often convenient to classify ingested ENMs (iENMs) as being either inorganic (such as TiO2, SiO2, Fe2O3, or Ag) or organic (such as lipid, protein, or carbohydrate), since the former tend to be indigestible and the latter are generally digestible. At present there is a relatively poor understanding of how different types of iENMs behave within the human gastrointestinal tract (GIT), and how the food matrix and biopolymers transform their physico-chemical properties and influence their gastrointestinal fate. This lack of knowledge confounds an understanding of their potential harmful effects on human health. The purpose of this article is to review our current understanding of the GIT fate of iENMs, and to highlight gaps where further research is urgently needed in assessing potential risks and toxicological implications of iENMs. In particular, a strong emphasis is given to the development of standardized screening methods that can be used to rapidly and accurately assess the toxicological properties of iENMs. PMID- 29568811 TI - Oxidative Stress and Metabolic Reprogramming in Cr(VI) Carcinogenesis. AB - Cr(VI)-containing compounds are well-established lung carcinogens. Chronic exposure of the normal human epithelial cells is able to induce malignant cell transformation, the first stage of metal carcinogenesis. These Cr(VI)-transformed cells exhibit increased level of antioxidants, reduced capacity of generating reactive oxygen species (ROS), and development of apoptosis resistance, promoting tumorigenesis of Cr(VI)-transformed cells, the second stage of metal carcinogenesis. The mechanism of Cr(VI) induced carcinogenesis is still under investigation. Recent studies indicate that ROS play a positive role in the first stage while a negative role in the second stage. Transformed cells adapt metabolism to support tumor initiation and progression. Altered metabolic activities directly participate in the process of cell transformation or support a large requirement for nucleotides, amino acids, and lipids for tumor growth. In malignantly Cr(VI)-transformed cells, mitochondrial oxidative phosphorylation is defective, and pentose phosphate pathway, glycolysis, and glutaminolysis are upregulated. These metabolic reprogramming supports rapid cell proliferation and contributes to tumorigenesis of Cr(VI)-transformed cells. This article summarizes the current progress in the studies of metabolic reprogramming and Cr(VI) carcinogenesis with emphasis on the metabolic enzymes and oxidative stress related major oncogenic pathways. PMID- 29568813 TI - Hypoglycemia in a Patient With a Polyhormonal Pancreatic Neuroendocrine Tumor With Evidence of Endocrine Progenitors. AB - A 55-year-old woman with a large polyhormonal neuroendocrine tumor with unusual pathology is described. The patient presented with intermittent neuroglycopenic symptoms between more protracted asymptomatic periods occurring over the preceding 4 years. During a diagnostic 72-hour inpatient fast, she exhibited hypoglycemia at 70 hours after initiation. On computed tomography scan, a 6-cm mass was identified at the pancreatic head. The patient underwent a pylorus preserving pancreaticoduodenectomy, and pathology was positive for cells staining for pancreatic polypeptide, insulin, and occasional double hormone (insulin plus pancreatic polypeptide)-positive cells. In addition, the tumor exhibited broad staining for ALDH1A3, a new marker of endocrine progenitors. This case serves to highlight the clinical and pathologic variability of insulin-producing tumors and raises the potential for cells in these tumors to exhibit hormone interconversion and progenitor-like states. PMID- 29568812 TI - Retinoic acid-related Orphan Receptor gamma (RORgamma): connecting sterol metabolism to regulation of the immune system and autoimmune disease. AB - Cholesterol and its metabolites are bioactive lipids that interact with and regulate the activity of various proteins and signaling pathways that are implicated in the control of a variety of physiological and pathological processes. Recent studies revealed that retinoic acid-related orphan receptors, RORalpha and gamma, members of the ligand-dependent nuclear receptor superfamily, exhibit quite a wide binding specificity for a number of sterols. Several cholesterol intermediates and metabolites function as natural ligands of RORalpha and RORgamma and act as agonists or inverse agonists. Changes in cholesterol homeostasis that alter the level or type of sterol metabolites in cells, can either enhance or inhibit ROR transcriptional activity that subsequently result in changes in the physiological processes regulated by RORs, including various immune responses and metabolic pathways. Consequently, this might negatively or positively impact pathologies, in which RORs are implicated, such as autoimmune disease, inflammation, metabolic syndrome, cancer, and several neurological disorders. Best studied are the links between cholesterol metabolism, RORgammat activity, and their regulation of Th17 differentiation and autoimmune disease. The discovery that Th17-dependent inflammation is significantly attenuated in RORgamma-deficient mice in several experimental autoimmune disease models, initiated a search for ROR modulators that led to the identification of a number of small molecular weight RORgamma inverse agonists. The inverse agonists suppress Th17 differentiation and IL-17 production and protect against autoimmunity. Together, these studies suggest that RORgammat may provide an attractive therapeutic target in the management of several (inflammatory) diseases. PMID- 29568814 TI - GLP-1 and Insulin Recruit Muscle Microvasculature and Dilate Conduit Artery Individually But Not Additively in Healthy Humans. AB - Context: Glucagon-like peptide-1 (GLP-1) and insulin increase muscle microvascular perfusion, thereby increasing tissue endothelial surface area and nutrient delivery. Objective: To examine whether GLP-1 and insulin act additively on skeletal and cardiac microvasculature and conduit artery. Design: Healthy adults underwent three study protocols in random order. Setting: Clinical Research Unit at the University of Virginia. Methods: Overnight-fasted participants received an intravenous infusion of GLP-1 (1.2 pmol/kg/min) or normal saline for 150 minutes with or without a 2-hour euglycemic insulin clamp (1 mU/kg/min) superimposed from 30 minutes onward. Skeletal and cardiac muscle microvascular blood volume (MBV), flow velocity, and flow; brachial artery diameter, flow velocity, and blood flow; and pulse wave velocity (PWV) were measured. Results: GLP-1 significantly increased skeletal and cardiac muscle MBV and microvascular blood flow (MBF) after 30 minutes; these remained elevated at 150 minutes. Insulin also increased skeletal and cardiac muscle MBV and MBF. Addition of insulin to GLP-1 did not further increase skeletal and cardiac muscle MBV and MBF. GLP-1 and insulin increased brachial artery diameter and blood flow, but this effect was not additive. Neither GLP-1, insulin, nor GLP-1 and insulin altered PWV. Combined GLP-1 and insulin infusion did not result in higher whole body glucose disposal. Conclusion: GLP-1 and insulin at physiological concentrations acutely increase skeletal and cardiac muscle microvascular perfusion and dilate conduit artery in healthy adults; these effects are not additive. Thus, GLP-1 and insulin may regulate skeletal and cardiac muscle endothelial surface area and nutrient delivery under physiological conditions. PMID- 29568817 TI - Biological Interpretation of Morphological Patterns in Histopathological Whole Slide Images. AB - We propose a framework for studying visual morphological patterns across histopathological whole-slide images (WSIs). Image representation is an important component of computer-aided decision support systems for histopathological cancer diagnosis. Such systems extract hundreds of quantitative image features from digitized tissue biopsy slides and produce models for prediction. The performance of these models depends on the identification of informative features for selection of appropriate regions-of-interest (ROIs) from heterogeneous WSIs and for development of models. However, identification of informative features is hindered by the semantic gap between human interpretation of visual morphological patterns and quantitative image features. We address this challenge by using data mining and information visualization tools to study spatial patterns formed by features extracted from sub-sections of WSIs. Using ovarian serous cystadenocarcinoma (OvCa) WSIs provided by the cancer genome atlas (TCGA), we show that (1) individual and (2) multivariate image features correspond to biologically relevant ROIs, and (3) supervised image feature selection can map histopathology domain knowledge to quantitative image features. PMID- 29568816 TI - A Major Population of Functional KLRG1- ILC2s in Female Lungs Contributes to a Sex Bias in ILC2 Numbers. AB - Humans show significant sex differences in the incidence and severity of respiratory diseases, including asthma and virus infection. Sex hormones contribute to the female sex bias in type 2 inflammation associated with respiratory diseases, consistent with recent reports that female lungs harbor greater numbers of GATA-3-dependent group 2 innate lymphoid cells (ILC2s). In this study, we determined whether sex hormone levels govern sex differences in the numbers, phenotype, and function of ILC2s in the murine lung and bone marrow (BM). Our data show that lungs of female mice harbor significantly greater ILC2 numbers in homeostasis, in part due to a major subset of ILC2s lacking killer cell lectin like receptor G1 (KLRG1), a population largely absent in male lungs. The KLRG1- ILC2s were capable of type 2 cytokine production and increased with age after sexual maturity, suggesting that a unique functional subset exists in females. Experiments with gonadectomized mice or mice bearing either global or lymphocyte restricted estrogen receptor alpha (Esr1) deficiency showed that androgens rather than estrogens regulated numbers of the KLRG1- ILC2 subset and ILC2 functional capacity in the lung and BM, as well as levels of GATA-3 expression in BM ILC2s. Furthermore, the frequency of BM PLZF+ ILC precursors was higher in males and increased by excess androgens, suggesting that androgens act to inhibit the transition of ILC precursors to ILC2s. Taken together, these data show that a functional subset of KLRG1- ILC2s in females contributes to the sex bias in lung ILC2s that is observed after reproductive age. PMID- 29568819 TI - Sublanguage Corpus Analysis Toolkit: A tool for assessing the representativeness and sublanguage characteristics of corpora. AB - Sublanguages are varieties of language that form "subsets" of the general language, typically exhibiting particular types of lexical, semantic, and other restrictions and deviance. SubCAT, the Sublanguage Corpus Analysis Toolkit, assesses the representativeness and closure properties of corpora to analyze the extent to which they are either sublanguages, or representative samples of the general language. The current version of SubCAT contains scripts and applications for assessing lexical closure, morphological closure, sentence type closure, over represented words, and syntactic deviance. Its operation is illustrated with three case studies concerning scientific journal articles, patents, and clinical records. Materials from two language families are analyzed-English (Germanic), and Bulgarian (Slavic). The software is available at sublanguage.sourceforge.net under a liberal Open Source license. PMID- 29568818 TI - Developing Robust Predictive Models for Head and Neck Cancer across Microarray and RNA-seq Data. AB - Increased understanding of the transcriptomic patterns underlying head and neck squamous cell carcinoma (HNSCC) can facilitate earlier diagnosis and better treatment outcomes. Integrating knowledge from multiple studies is necessary to identify fundamental, consistent gene expression signatures that distinguish HNSCC patient samples from disease-free samples, and particularly for detecting HNSCC at an early pathological stage. This study utilizes feature integration and heterogeneous ensemble modeling techniques to develop robust models for predicting HNSCC disease status in both microarray and RNAseq datasets. Several alternative models demonstrated good performance, with MCC and AUC values exceeding 0.8. These models were also applied to discriminate between early pathological stage HNSCC and normal RNA-seq samples, showing encouraging results. The predictive modeling workflow was integrated into a software tool with a graphical user interface. This tool enables HNSCC researchers to harness frequently observed transcriptomic features and ensembles of previously developed models when investigating new HNSCC gene expression datasets. PMID- 29568820 TI - SuperCAT: The (New and Improved) Corpus Analysis Toolkit. AB - This paper reports SuperCAT, a corpus analysis toolkit. It is a radical extension of SubCAT, the Sublanguage Corpus Analysis Toolkit, from sublanguage analysis to corpus analysis in general. The idea behind SuperCAT is that representative corpora have no tendency towards closure-that is, they tend towards infinity. In contrast, non-representative corpora have a tendency towards closure-roughly, finiteness. SuperCAT focuses on general techniques for the quantitative description of the characteristics of any corpus (or other language sample), particularly concerning the characteristics of lexical distributions. Additionally, SuperCAT features a complete re-engineering of the previous SubCAT architecture. PMID- 29568821 TI - Reproducibility in Natural Language Processing: A Case Study of Two R Libraries for Mining PubMed/MEDLINE. AB - There is currently a crisis in science related to highly publicized failures to reproduce large numbers of published studies. The current work proposes, by way of case studies, a methodology for moving the study of reproducibility in computational work to a full stage beyond that of earlier work. Specifically, it presents a case study in attempting to reproduce the reports of two R libraries for doing text mining of the PubMed/MEDLINE repository of scientific publications. The main findings are that a rational paradigm for reproduction of natural language processing papers can be established; the advertised functionality was difficult, but not impossible, to reproduce; and reproducibility studies can produce additional insights into the functioning of the published system. Additionally, the work on reproducibility lead to the production of novel user-centered documentation that has been accessed 260 times since its publication-an average of once a day per library. PMID- 29568822 TI - Ethical Issues in Corpus Linguistics And Annotation: Pay Per Hit Does Not Affect Effective Hourly Rate For Linguistic Resource Development On Amazon Mechanical Turk. AB - Ethical issues reported with paid crowdsourcing include unfairly low wages. It is assumed that such issues are under the control of the task requester. Can one control the amount that a worker earns by controlling the amount that one pays? 412 linguistic data development tasks were submitted to Amazon Mechanical Turk. The pay per HIT was manipulated through a range of values. We examined the relationship between the pay that is offered per HIT and the effective pay rate. There is no such relationship. Paying more per HIT does not cause workers to earn more: the higher the pay per HIT, the more time workers spend on them (R = 0.92). So, the effective hourly rate stays roughly the same. The finding has clear implications for language resource builders who want to behave ethically: other means must be found in order to compensate workers fairly. The findings of this paper should not be taken as an endorsement of unfairly low pay rates for crowdsourcing workers. Rather, the intention is to point out that additional measures, such as pre-calculating and communicating to the workers an average hourly, rather than per-task, rate must be found in order to ensure an ethical rate of pay. PMID- 29568823 TI - Graph-Constrained Sparse Construction of Longitudinal Diffusion-Weighted Infant Atlases. AB - Constructing longitudinal diffusion-weighted atlases of infant brains poses additional challenges due to the small brain size and the dynamic changes in the early developing brains. In this paper, we introduce a novel framework for constructing longitudinally-consistent diffusion-weighted infant atlases with improved preservation of structural details and diffusion characteristics. In particular, instead of smoothing diffusion signals by simple averaging, our approach fuses the diffusion-weighted images in a patch-wise manner using sparse representation with a graph constraint that encourages spatiotemporal consistency. Diffusion-weighted atlases across time points are jointly constructed for patches that are correlated in time and space. Compared with existing methods, including the one using sparse representation with l2,1 regularization, our approach generates longitudinal infant atlases with much richer and more consistent features of the developing infant brain, as shown by the experimental results. PMID- 29568824 TI - Multimodal Hyper-connectivity Networks for MCI Classification. AB - Hyper-connectivity network is a network where every edge is connected to more than two nodes, and can be naturally denoted using a hyper-graph. Hyper connectivity brain network, either based on structural or functional interactions among the brain regions, has been used for brain disease diagnosis. However, the conventional hyper-connectivity network is constructed solely based on single modality data, ignoring potential complementary information conveyed by other modalities. The integration of complementary information from multiple modalities has been shown to provide a more comprehensive representation about the brain disruptions. In this paper, a novel multimodal hyper-network modelling method was proposed for improving the diagnostic accuracy of mild cognitive impairment (MCI). Specifically, we first constructed a multimodal hyper-connectivity network by simultaneously considering information from diffusion tensor imaging and resting-state functional magnetic resonance imaging data. We then extracted different types of network features from the hyper-connectivity network, and further exploited a manifold regularized multi-task feature selection method to jointly select the most discriminative features. Our proposed multimodal hyper connectivity network demonstrated a better MCI classification performance than the conventional single modality based hyper-connectivity networks. PMID- 29568825 TI - q-Space Upsampling Using x-q Space Regularization. AB - Acquisition time in diffusion MRI increases with the number of diffusion-weighted images that need to be acquired. Particularly in clinical settings, scan time is limited and only a sparse coverage of the vast q-space is possible. In this paper, we show how non-local self-similar information in the x-q space of diffusion MRI data can be harnessed for q-space upsampling. More specifically, we establish the relationships between signal measurements in x-q space using a patch matching mechanism that caters to unstructured data. We then encode these relationships in a graph and use it to regularize an inverse problem associated with recovering a high q-space resolution dataset from its low-resolution counterpart. Experimental results indicate that the high-resolution datasets reconstructed using the proposed method exhibit greater quality, both quantitatively and qualitatively, than those obtained using conventional methods, such as interpolation using spherical radial basis functions (SRBFs). PMID- 29568826 TI - Online Statistical Inference for Large-Scale Binary Images. AB - We present a unified online statistical framework for quantifying a collection of binary images. Since medical image segmentation is often done semi-automatically, the resulting binary images may be available in a sequential manner. Further, modern medical imaging datasets are too large to fit into a computer's memory. Thus, there is a need to develop an iterative analysis framework where the final statistical maps are updated sequentially each time a new image is added to the analysis. We propose a new algorithm for online statistical inference and apply to characterize mandible growth during the first two decades of life.

PMID- 29568829 TI - Spin-orbit effects in optical spectra of gold-silver trimers. AB - Cationic gold-silver trimers are ideal model systems for the evaluation of relativistic electronic structure theories. The closed-shell triangles allow one to test density functional and wavefunction-based methods in their prediction of optical properties, as dependent on composition and symmetry. Here we present the gas-phase optical spectra of AgNAu3-N+ (N = 0-3) clusters recorded by longitudinal photodissociation spectroscopy in the photon energy range 1.9-4.4 eV. The experimental data are compared to excited electronic state calculations in the framework of all-electron range-separated time-dependent density functional and equation-of-motion coupled cluster theory using two-component as well as the spin-free scalar relativistic theories. In particular, it is shown that for mixed trimers scalar-relativistic corrections are insufficient and a two component approach becomes obligatory for a correct description of optical response properties including both spin-orbit coupling and charge-transfer effects. PMID- 29568830 TI - Theoretical aspects in structural distortion and the electronic properties of lithium peroxide under high pressure. AB - The structural phase transition and electronic properties of Li2O2 under pressures up to 500 GPa have been investigated using first-principles calculations. Two new structural phase transitions have been proposed at pressures around 75 GPa from the P63/mmc structure to the P21 structure and around 136 GPa from the P21 structure to the P21/c structure. The calculated phonon spectra have confirmed the dynamical stability of these structures. The pressure dependence of the lattice dynamics, O-O bond length, and band gaps in Li2O2 have also been reported. The band gaps of the P63/mmc, P21, and P21/c structures calculated by PBE and HSE06 have shown increasing trends with increasing pressure. Interestingly, the P63/mmc band gap and c/a ratio have significantly decreased with the increasing O-O bond length and ELF value around 11 and 40 GPa. At these pressures, the phonon frequency of the O-O stretching modes has softened. This finding reveals the effects of structural distortion in three phases of Li2O2. Our study provides structural understanding and the electronic properties of Li2O2 under high pressure, which might be useful for investigating the charge transport through Li2O2 in lithium-air batteries and CO2 capture. PMID- 29568831 TI - Designing a porous-crystalline structure of beta-Ga2O3: a potential approach to tune its opto-electronic properties. AB - beta-Ga2O3 has drawn recent attention as a state-of-the-art electronic material due to its stability, optical transparency and appealing performance in power devices. However, it has also found a wider range of opto-electronic applications including photocatalysis, especially in its porous form. For such applications, a lower band gap must be obtained and an electron-hole spatial separation would be beneficial. Like many other metal oxides (e.g. Al2O3), Ga2O3 can also form various types of porous structure. In the present study, we investigate how its optical and electronic properties can be changed in a particular porous structure with stoichiometrically balanced and extended vacancy channels. We apply a set of first principles computational methods to investigate the formation and the structural, dynamic, and opto-electronic properties. We find that such an extended vacancy channel is mechanically stable and has relatively low formation energy. We also find that this results in a spatial separation of the electron and hole, forming a long-lived charge transfer state that has desirable characteristics for a photocatalyst. In addition, the electronic band gap reduces to the vis-region unlike the transparency in the pure beta-Ga2O3 crystal. Thus, our systematic study is promising for the application of such a porous structure of beta-Ga2O3 as a versatile electronic material.

Adduct 1b catalyzes intermolecular hydroamination of aromatic alkynes and amines under mild conditions to afford aromatic imines.

PMID- 29568833 TI - Prediction of optimal structural water concentration for maximized performance in tunnel manganese oxide electrodes. AB - Crystal water has been shown to stabilize next-generation energy storage electrodes with structural tunnels to accommodate cation intercalation, but the stabilization mechanism is poorly understood. In this study, we present a simple physical model to explain the energetics of interactions between the electrode crystal lattice, structural water, and electrochemically cycled ions. Our model is applied to understand the effects of crystal water on sodium ion intercalation in a tunnel manganese oxide structure, and we predict that precisely controlling the crystal water concentration can optimize the ion intercalation voltage and capacity and promote stable cycling. The analysis yields a critical structural water concentration by accounting for the interplay between elastic and electrostatic contributions to the free energy. Our predictions are validated with first-principles calculations and electrochemical measurements. The theoretical framework used here can be extended to predict critical concentrations of stabilizing molecules to optimize performance in next generation battery materials. PMID- 29568834 TI - Measurement of the mechanical properties of single Synechocystis sp. strain PCC6803 cells in different osmotic concentrations using a robot-integrated microfluidic chip. AB - Synechocystis sp. strain PCC6803 (Synechocystis) is a model microorganism and its mechanosensitive (MS) channels play important roles in its osmoadaptation mechanism. When the osmotic concentration of the culture environment changes, the inner pressure of the cell also changes due to the transportation of water through ion channels. Because the tension in the cell membrane relates to the inner pressure, we expect that the response of the MS channels to an osmotic concentration change could be evaluated by measuring their mechanical properties. Here, we propose a system for the measurement of the mechanical properties of a single Synechocystis cell. We developed a robot-integrated microfluidic chip combined with optical tweezers. The chip has an external actuated pushing probe and a force sensor probe. A single cell was located between the tip of both probes using the optical tweezers and was then deformed using the probes. As a result, we could measure the force and deformation and compare the Young's moduli of two groups: a group of wild type cells and a group of mutant (genetically modified) cells with a defect in the MS channels, at three different osmotic concentrations. The results showed that the Young's modulus of each group changed according to the osmotic concentration, while changes in cell size were too small to be detected. These results confirmed that the proposed evaluation method provides an understanding of the physiological function of MS channels for keeping the cell integrity of microorganisms when the cells are exposed to different external osmotic changes.

AB - Luminescent copper nanoclusters (CuNCs) constitute a very active research topic due to their unique properties and lower cost than gold and silver NCs. In this study, we report a new, facile, and rapid top-down etching method for synthesizing luminescent CuNCs, using Cu nanoparticles (CuNPs) as the precursor and ammonia (NH3) as the etchant. The etching mechanism is systematically investigated and the optical and structural properties of the obtained CuNCs are carefully studied. The NH3-triggered etching process is very fast and the newly generated CuNCs can emit strong green fluorescence with a high quantum yield. Moreover, by coupling the urease-catalyzed hydrolysis of urea with the NH3 induced etching of CuNPs, we developed a novel fluorescence turn-on assay for urea. The linear range for urea detection is from 0.25 to 5 mM, and the limit of detection is 0.01 mM. This novel sensing approach, with good sensitivity and excellent selectivity, is then successfully utilized to detect urea in human serum samples, demonstrating its great potential in clinical diagnosis. In addition, the proposed coupling method can be extended to monitor other analytes that influence the size-focusing etching process, allowing metal NCs to be used to construct diverse chemosensors and biosensors. PMID- 29568838 TI - A unifying view of the broad-spectrum antiviral activity of RSAD2 (viperin) based on its radical-SAM chemistry. AB - RSAD2 (cig-5), also known as viperin (virus inhibitory protein, endoplasmic reticulum associated, interferon inducible), is a member of the radical S adenosylmethionine (SAM) superfamily of enzymes. Since the discovery of this enzyme more than a decade ago, numerous studies have shown that it exhibits antiviral activity against a wide range of viruses. However, there is no clear picture demonstrating the mechanism by which RSAD2 restricts the replication process of different viruses, largely because there is no direct evidence describing its in vivo enzymatic activity. As a result, a multifunctionality model has emerged. According to this model the mechanism by which RSAD2 restricts replication of different viruses varies and in many cases is not dependent on the radical-SAM chemistry of RSAD2. If the radical-SAM activity of RSAD2 is not required for its antiviral function, the question worth asking is: why does the cellular defence mechanism induce the expression of the radical-SAM enzyme RSAD2, which is metabolically expensive due to the requirement for a [4Fe-4S] cluster and usage of SAM? Here, in contrast to the multifunctionality view, I put forward a unifying model. I postulate that the radical-SAM activity of RSAD2 modulates cellular metabolic pathways essential for viral replication and/or cell proliferation and survival. As a result, its catalytic activity restricts the replication of a wide range of viruses via a common cellular function. This view is based on recent discoveries hinting towards possible substrates of RSAD2, re evaluation of previous studies regarding the antiviral activity of RSAD2, and accumulating evidence suggesting a role of human RSAD2 in the metabolic reprogramming of cells. PMID- 29568839 TI - Potassium fluoride activation for the nucleophilic fluorination reaction using 18 crown-6, [2.2.2]-cryptand, pentaethylene glycol and comparison with the new hydro crown scaffold: a theoretical analysis. AB - Activation of potassium fluoride salt for selective and fast nucleophilic fluorination requires its solubilization and stabilization of the respective transition state. This goal can be achieved through control of the nano environment around the reactants via cation or ion-pair binding catalysis. In this work, six different species were theoretically investigated as promoters and catalysts for nucleophilic fluorination: tri-tert-butanolamine, 18-crown-6, pentaethylene glycol, [2.2.2]-cryptand, and two new hydroxylated crown ethers (hydro-crowns). Calculations using the PBE functional and the LPNO-CEPA method, as well as the SMD continuum model, were carried out for the SN2 reaction of KF with ethyl bromide in toluene solution as a model system. The present study points out that [2.2.2]-cryptand is the most effective promoter of the reaction when using stoichiometric quantities. In the case of a catalytic process, the new DB18C6-4OH is the most effective molecule considering only a 1 : 1 complex. The hydroxyl groups are important for the solubilization of potassium fluoride and for the catalytic cycle. Nevertheless, the DB18C6-4OH hydro-crown can form a 2 : 2 complex and is needed to add bulk groups close to the hydroxyls to avoid dimerization. The calculated overall free energy of activation for reactions promoted by 18-crown-6, pentaethylene glycol, and [2.2.2]-cryptand is in good agreement with the experimental data.

AB - INTRODUCTION: The introduction of the residency programme in Singapore allows medical students to apply for residency in their graduating year. Our study aimed to determine the interest levels and motivating factors for pursuing emergency medicine (EM) as a career among medical students in Singapore. METHODS: A self administered questionnaire was distributed to Year 1-5 medical students in 2012. Participants indicated their interest in pursuing EM as a career and the degree to which a series of variables influenced their choices. Influencing factors were analysed using multinomial logistic regression. RESULTS: A total of 800 completed questionnaires were collected. 21.0% of the participants expressed interest in pursuing EM. Perceived personality fit and having done an elective in EM were strongly positive influencing factors. Junior medical students were more likely to cite the wide diversity of medical conditions and the lack of a long-term doctor-patient relationship to be negative factors, while senior medical students were more likely to cite personality fit and perceived prestige of EM as negative factors. CONCLUSION: Careful selection of EM applicants is important to the future development of EM in Singapore. Our study showed that personality fit might be the most important influencing factor in choosing EM as a career. Therefore, greater effort should be made to help medical students explore their interest in and suitability for a particular specialty. These include giving medical students earlier exposure to EM, encouraging participation in student interest groups and using appropriate personality tests for career guidance.

AB - Peritoneal metastases (PM) are the common endpoint for patients with advanced gastrointestinal cancers. PM from these cancers are often managed in a similar fashion to other sites of systemic metastases, but the following must be taken into consideration. (a) PM do not respond to systemic chemotherapy in the same fashion as liver and lung metastases. (b) PM cause local problems, resulting in disruption of chemotherapy. (c) Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) actually work for PM. (d) PM are not easily detected on imaging modalities. There has been mounting evidence of the effectiveness of CRS-HIPEC at prolonging survival in selected patients with colorectal and gastric PM, but there remains a reluctance to explore this treatment modality. This is likely because of the perceived morbidity and mortality. An effective management strategy employing CRS-HIPEC for selected patients with gastrointestinal PM can only be achieved if a concerted effort is made to understand this disease and address the concerns regarding this treatment.

AB - Exploring and understanding biological and pathological changes are of great significance for early diagnosis and therapy of diseases. Optical sensing and imaging approaches have experienced major progress in this field. Particularly, an emergence of various functional optical nanoprobes has provided enhanced sensitivity, specificity, targeting ability, as well as multiplexing and multimodal capabilities due to improvements in their intrinsic physicochemical and optical properties. However, one of the biggest challenges of conventional optical nanoprobes is their absolute intensity-dependent signal readout, which causes inaccurate sensing and imaging results due to the presence of various analyte-independent factors that can cause fluctuations in their absolute signal intensity. Ratiometric measurements provide built-in self-calibration for signal correction, enabling more sensitive and reliable detection. Optimizing nanoprobe designs with ratiometric strategies can surmount many of the limitations encountered by traditional optical nanoprobes. This review first elaborates upon existing optical nanoprobes that exploit ratiometric measurements for improved sensing and imaging, including fluorescence, surface enhanced Raman scattering (SERS), and photoacoustic nanoprobes. Next, a thorough discussion is provided on design strategies for these nanoprobes, and their potential biomedical applications for targeting specific biomolecule populations (e.g. cancer biomarkers and small molecules with physiological relevance), for imaging the tumor microenvironment (e.g. pH, reactive oxygen species, hypoxia, enzyme and metal ions), as well as for intraoperative image guidance of tumor-resection procedures.

AB - Manual examination of the peripheral blood smear (PBS) is currently performed on a fraction of samples sent for automated complete cell count. 39 children (age range 0-16.2 years) referred to a private paediatric practice during a 16-month period were retrospectively reviewed. Clinical scenarios, haematological features, laboratory-initiated PBS review, haematologist's PBS review and final diagnosis were described. Clinical indications included isolated thrombocytopenia (n = 10), unexplained bruises (n = 5), acute febrile illnesses (n = 11), anaemia (n = 8) and others (n = 5). The laboratory reviewed the PBS in 30 cases according to preset criteria and made no conclusive remarks. All slides were reviewed by a haematologist and a diagnosis was made in 27 (69%) cases, including 7 (78%) of the nine slides the laboratory did not review. The practice of laboratory initiated PBS review requires re-evaluation. Haematologist-reviewed PBS is an important diagnostic tool for children with anaemia, bleeding disorders and acute febrile illnesses. PMID- 29568848 TI - Clinics in diagnostic imaging (184). Fat embolism syndrome (FES). AB - A 23-year-old Indian man presented with shortness of breath and new-onset confusion along with a rash on his chest on Postoperative Day 2, following internal fixation of his femur fracture. Although computed tomography pulmonary angiography was negative for filling defects in the pulmonary vasculature, it showed mosaic attenuation changes with some interlobular septal thickening. Magnetic resonance imaging of the brain showed patchy signal abnormalities, predominantly in the grey-white matter junction region with extensive susceptibility artefacts, consistent with petechial haemorrhages. The laboratory work-up showed thrombocytopenia and anaemia. A diagnosis of fat embolism syndrome was established, based on the clinical presentation combined with laboratory and imaging findings. The clinical and imaging features of fat embolism syndrome are discussed. PMID- 29568849 TI - Intravascular large B-cell lymphoma presenting as panniculitis clinically: a case report.

This is especially of concern in an ageing population like that of Singapore. Osteoporotic patients are at risk of fractures, which can result in increased morbidity and mortality. The use of antiresorptive therapy with bisphosphonates or denosumab has been proven to reduce fracture risk. However, the use of these medications has rarely been associated with the development of osteonecrosis of the jaw, a potentially debilitating condition affecting one or both jaws. Appropriate understanding of the patient's antiresorptive therapy regime, as well as early institution of preventive dental measures, can play an important role in preventing medication related osteonecrosis of the jaw (MRONJ). Regular monitoring and prompt referral to specialist care is warranted for patients with established MRONJ.

PMID- 29568855 TI - Prevailing practices in airway management: a prospective single-centre observational study of endotracheal intubation. AB - INTRODUCTION: Airway management during anaesthesia has potential difficulties and risks. We aimed to investigate the utility of routine airway assessment for predicting difficult tracheal intubation, review the prevailing practice of videolaryngoscope use amongst anaesthetists in a teaching hospital and determine the incidence of intraoperative and postoperative airway-related complications. METHODS: A prospective observational study of 1,654 patients undergoing general anaesthesia with endotracheal intubation over a seven-month period was performed. Data regarding airway and anaesthetic management was collected and analysed. RESULTS: Videolaryngoscopes were used as the first-choice equipment in 60.5% of the cohort. The incidence of difficult intubation was 2.1%, of which 45.7% of cases were unanticipated. The sensitivity of airway assessment was 54.3%, with a positive predictive value of 8.1%. When difficult intubation was anticipated, more videolaryngoscopes were used as the first equipment of choice compared to the Macintosh laryngoscope (p < 0.001). In the Macintosh group, more patients required a change of airway equipment (p = 0.015), but the number of intubation attempts was similar (p = 0.293). The incidence of intraoperative (p = 0.920) and postoperative complications (p = 0.380) were similar in both groups. CONCLUSION: Using the current predictors of difficult intubation, half of the difficult airways we encountered were unanticipated. Videolaryngoscopes were preferred when difficulty was anticipated and were also used in routine tracheal intubation. PMID- 29568856 TI - Approach to the forgetful patient. AB - Singapore has an ageing population with a projected 53,000 people aged >= 60 years living with dementia by 2020. Primary care doctors have the opportunity to initiate early work-up for reversible causes of cognitive dysfunction, allowing identification of comorbidities and discussion of medical therapy options. Early diagnosis confers the sick role on the patient, which allays frustration and explains events and behaviour that may have strained relationships with family and friends. The patient can be encouraged to plan for future health and personal care options with a Lasting Power of Attorney and/or Advance Care Planning. Objective cognitive tests (e.g. abbreviated mental test and Mini-Mental State Examination) and brain imaging are adjuncts that help in formulating the diagnosis. Referral to a hospital memory clinic activates a multidisciplinary team approach to dementia, including clinical consultation, dementia counselling, physiotherapy sessions on gait/fall prevention, occupational therapy sessions on cognitive stimulation and caregiver training. PMID- 29568857 TI - Accelerated inflammation and oxidative stress induced by LPS in acute lung injury: Iotanhibition by ST1926. AB - Bioavailable and less toxic synthetic retinoids, such as the atypical adamantyl retinoid ST1926, have been well developed and investigated in clinical trials for many diseases. The aim of our study was to explore the role of ST1926 in lipopolysaccharide (LPS)-induced acute lung injury (ALI) and to reveal the possible molecular mechanism. Mice were treated with LPS to induce acute lung injury followed by ST1926 administration. After LPS induction, mice administered with ST1926 showed lower inflammation infiltration in bronchoalveolar lavage (BAL) fluid, and pro-inflammatory cytokines, including interleukin-1beta (IL 1beta), IL-18, IL-6 and tumor necrosis factor-alpha (TNF-alpha) in serum and lung tissue samples obtained from mice. In addition, western blot assays suggested that ST1926 suppressed nuclear factor-kappaB (NF-kappaB), inhibitor-kappaB kinase alpha (IkappaBalpha) and IkappaB kinase (IKKalpha), as well as Toll-like receptor 4 (TLR4) induced by LPS. In addition, reactive oxygen species (ROS) stimulated by LPS was also suppressed for ST1926 through inhibiting p38 and extracellular receptor kinase (ERK) signaling pathway. Taken together, the data here indicated that ST1926 may be of potential value in treating acute lung injury through inflammation and ROS suppression via inactivating TLR4/NF-kappaB and p38/ERK1/2 signaling pathways. PMID- 29568858 TI - Cardioprotective effect of rosuvastatin against isoproterenol-induced myocardial infarction injury in rats. AB - Rosuvastatin, a member of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, exerts various pharmacological activities. This study evaluated the cardioprotective effect of rosuvastatin on isoproterenol-induced myocardial infarction injury in rats. A rat model of myocardial infarction injury was induced by isoproterenol (ISO) for 2 consecutive days, rosuvastatin was administered for 8 weeks. The levels of myocardial infarct size, aspartate transaminase (AST), alanine transaminase (ALT), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) activities, as well as malondialdehyde (MDA) levels, superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT) activities and reduced glutathione (GSH) concentrations were determined. Hematoxylin and eosin staining was used to observe cardiac histological changes. Interleukin-1beta (IL-1beta) and IL-18 levels in heart tissues were detected with ELISA kits. The mRNA and protein levels of NOD-like receptor superfamily, pyrin domain containing 3 (NLRP3) inflammasome were measured by qRT-PCR and western blot analysis, respectively. Our results showed that treatment with rosuvastatin reduced myocardial infract area, ameliorated histopathological alterations in myocardium, and decreased activities of myocardial injury marker enzymes in ISO induced rats. In addition, rosuvastatin remarkably restored ISO-induced elevation of lipid peroxidation and decrease of antioxidants, significantly reduced myocardial pro-inflammatory cytokines concentrations in this animal model. Furthermore, rosuvastatin significantly inhibited the activation of NLRP3 inflammasome in this animal model. This study demonstrates that rosuvastatin significantly alleviates ISO-induced myocardial infarction injury. The mechanism is associated with attenuation of oxidative stress and inflammation, via the inhibition of NLRP3 inflammasome. PMID- 29568859 TI - Effects of three-dimensional collagen scaffolds on the expression profiles and biological functions of glioma cells. AB - Three-dimensional (3D) culture has been increasingly used to investigate tumor cell biology for improved simulation of the natural developing environment. However, the way in which 3D culture affects the gene expression and biological functions of glioma cells remains to be fully elucidated. In the present study, 3D culture environments were established using collagen scaffolds with different pore sizes, followed by the comparison of gene expression profiles and associated biological functions of glioma cells, including the U87, U251 and HS683 cell lines, in 3D collagen scaffolds with conventional two-dimensional (2D) cultured cells. Finally, the possible signaling pathways regulating these differences were investigated. It was found that the 3D collagen scaffold culture upregulated the expression of genes associated with stemness, cell cycle, apoptosis, epithelia mesenchymal transition, migration, invasion and glioma malignancy, and induced the corresponding functional changes. Apoptotic pathways, the Wnt pathway, Sonic Hedgehog pathway and Notch pathway, may be involved in the regulation of these changes. The aperture size of the collagen-scaffold did not appear to affect the gene expression or functions of the glioma cells. The results of the study suggested that the 3D collagen scaffold enhanced the malignancy of glioma cells and may be a promising in vitro platform for investigations of glioma. PMID- 29568860 TI - Esculin ameliorates cognitive impairment in experimental diabetic nephropathy and induces anti-oxidative stress and anti-inflammatory effects via the MAPK pathway. AB - Esculin is a derivative of coumarin, which is also an active ingredient of ash bark, and has antibacterial, anti-inflammatory, anti-allergy and skin protective effects. The underlying mechanism and protective effects of esculin on cognitive impairment in experimental diabetic nephropathy (DN) was investigated in the present study. Male C57BL/6J 6-week-old mice were injected intravenously with a single dose of streptozotocin (STZ; 30 mg/kg). At 2 weeks after the STZ injection, mice received intravenous injection with 5, 10 or 20 mg/kg esculin for 2 weeks. In the present study, the results of the Morris water maze test demonstrated that esculin significantly improved behavior and recognition memory in STZ-induced diabetic rats. Furthermore, treatment of STZ-induced diabetic rats with esculin significantly inhibited tumor necrosis factor-alpha, interleukin-6, malondialdehyde, monocyte chemoattractant protein-1 and intracellular adhesion molecule-1 activity levels, and increased the activity of superoxide dismutase, in the kidney, which was determined by ELISA. In addition, esculin treatment significantly suppressed the renal protein expression of activator protein 1, phosphorylated (p)-p38 mitogen activated protein kinase (MAPK) and p-c-Jun N terminal kinase, and increased p-extracellular signal regulated kinase 1/2 protein expression, in STZ-induced diabetic rats, as determined by western blotting. These results indicate that esculin may ameliorate cognitive impairment in experimental DN, and exert anti-oxidative stress and anti-inflammatory effects, via the MAPK signaling pathway. Thus, it may serve as a potential target for cognitive impairment of DN in the future. PMID- 29568861 TI - Neuroprotective effects of salidroside administration in a mouse model of Alzheimer's disease. AB - Salidroside administration improves memory in different models of learning. However, its influence on models of Alzheimer's disease (AD) has not been widely studied. In the present study, the therapeutic effect of salidroside was investigated in an animal model of AD. APPswe/PS1DeltaE9 mouse (n=20) were randomly divided into either the AD model group or the salidroside + AD model group (n=10 in each group), and C57BL/6J mouse (n=20) of identical age and genetic background were randomly divided into either the normal control (NC) group or the salidroside + NC group (n=10 in each group). The Morris water maze behavioral test was applied to all mice in order to investigate the effects of salidroside administration on learning and memory functions. The concentrations of malondialdehyde (MDA), glutathione (GSH) and nitrate in the hippocampus of the mice were determined, and hippocampal superoxide dismutase (SOD) activity was also determined. In addition, terminal deoxynucleotidyl-transferase-mediated dUTP nick end labeling was used to investigate the rate of neuronal apoptosis in the hippocampus. Furthermore, the concentrations of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were tested for in the brain tissues of AD mice. Learning and memory functions in AD mice were revealed to improve following administration of salidroside. Furthermore, salidroside administration was revealed to decrease the concentrations of MDA and nitrate in the hippocampus, decrease the apoptotic rate of hippocampal neurons, and increase the activity of SOD and the concentration of GSH in hippocampal tissue. In addition, it was demonstrated that salidroside administration suppressed the expression levels of IL-6 and TNF-alpha. In conclusion, this study revealed that the administration of salidroside could attenuate the effects of AD-associated memory and learning impairment in mice. Furthermore, it was demonstrated that the effects of salidroside administration on AD mice were, at least partially, via inhibition of brain oxidative/nitrosative damage, suppression of both IL-6 and TNF-alpha expression levels, and suppression of the hippocampal neuronal apoptotic rate. PMID- 29568862 TI - Overexpression of appoptosin promotes mitochondrial damage in MIN6 cells. AB - Damage to pancreatic beta-cells is closely associated with diabetes. However, the mechanism underlying injury to pancreatic beta-cells remains unclear, although hypoxia is considered as one of the leading causes. Appoptosin is a mitochondrial protein that promotes neuronal apoptosis. Studies conducted on appoptosin thus far have primarily focused on Alzheimer's disease, and have demonstrated that the expression of appoptosin is significantly increased in ischemic-reperfused rat brains, which indicates its close association with hypoxia. However, the role of appoptosin in pancreatic beta-cells, which are sensitive to hypoxia, remains unknown. Therefore, the current study aimed to investigate the function of appoptosin in pancreatic beta-cells in a hypoxic environment. Cobalt chloride (CoCl2) was used to mimic the hypoxic status of the cells. The results of a terminal deoxynucleotidyl transferase dUTP nick-end labeling assay demonstrated that CoCl2 promoted apoptosis in MIN6 mouse insulinoma cells, and western blotting and reverse transcription-quantitative polymerase chain reaction results demonstrated that the activation of appoptosin was induced, promoting mitochondrial damage and caspase 3 activation. Silencing of appoptosin using short hairpin RNA significantly reduced CoCl2-induced apoptosis in MIN6 cells. In conclusion, CoCl2 increased the expression of appoptosin, which aggravated mitochondrial damage in MIN6 cells. Therefore, inhibiting the expression of appoptosin may benefit pancreatic beta-cells survival during islet transplantation. PMID- 29568863 TI - TIPE-2 suppresses growth and aggressiveness of hepatocellular carcinoma cells through downregulation of the phosphoinositide 3-kinase/AKT signaling pathway. AB - Rapid proliferation and migration are the main features of hepatocellular carcinoma (HCC) cells, which serve an essential role in carcinogenesis and are a hallmark of cancer therapy resistance. Previous studies have reported that tumor necrosis factor-alpha-induced protein-8 like-2 (TIPE-2) is involved in cancer initiation and the progression of HCC. The present study aimed to clarify the role of TIPE-2 in HCC carcinogenesis, growth and aggressiveness. The effects of TIPE-2 on HCC were determined using colony forming and cell cycle analyses. Cell apoptosis, and growth and aggressiveness of HCC cells, were investigated following TIPE-2 treatment. Treatment with TIPE-2 markedly suppressed HCC cell proliferation and increased the number of cells in S phase of the cell cycle. The results demonstrated that TIPE-2 significantly inhibited growth, migration and invasion of HCC cells via the downregulation of tumor metastasis-associated genes. Flow cytometric analysis indicated that TIPE-2 promoted apoptosis of HCC cells via regulation of apoptosis-associated gene transcription. In addition, TIPE-2 administration downregulated the expression of phosphoinositide 3-kinase (PI3K) and protein kinase B (AKT) in HCC cells. In addition, TIPE-2 selectively decreased neuroblastoma Ras viral oncogene and p27 expression in HCC cells. In vivo assays revealed that TIPE-2 significantly inhibited tumor growth and prolonged animal survival by promoting apoptosis of tumor cells. The results of the present study indicated that TIPE-2 acts as an inhibitor of HCC cell growth and aggressiveness, and promotes apoptosis, thus suggesting that TIPE-2 may inhibit the metastasis-associated PI3K/AKT signaling cascade and may arrest the tumor cell cycle. These findings provide a potential molecular mechanism by which TIPE-2 promotes apoptosis of HCC cells. PMID- 29568864 TI - Protective effect of curcumin against ultraviolet A irradiation-induced photoaging in human dermal fibroblasts. AB - Ultraviolet (UV) radiation induces DNA damage, oxidative stress, and inflammatory processes in skin, resulting in photoaging. Natural botanicals have gained considerable attention due to their beneficial protection against the harmful effects of UV irradiation. The present study aimed to evaluate the ability of curcumin (Cur) to protect human dermal fibroblasts (HDFs) against ultraviolet A (UVA)-induced photoaging. HDFs were treated with 0-10 uM Cur for 2 h and subsequently exposed to various intensities of UVA irradiation. The cell viability and apoptotic rate of HDFs were investigated by MTT and flow cytometry assays, respectively. The effect of UVA and Cur on the formation of reactive oxygen species (ROS), malondialdehyde levels, which are an indicator of ROS, and the levels/activity of antioxidative defense proteins, including glutathione, superoxide dismutase and catalase, were evaluated using 2',7'-dichlorofluorescin diacetate and commercial assay kits. Furthermore, western blotting was performed to determine the levels of proteins associated with endoplasmic reticulum (ER) stress, the apoptotic pathway, inflammation and the collagen synthesis pathway. The results demonstrated that Cur reduced the accumulation of ROS and restored the activity of antioxidant defense enzymes, indicating that Cur minimized the damage induced by UVA irradiation in HDFs. Furthermore, western blot analysis demonstrated that Cur may attenuate UVA-induced ER stress, inflammation and apoptotic signaling by downregulating the protein expression of glucose-regulated protein 78, C/EBP-homologous protein, nuclear factor-kappaB and cleaved caspase 3, while upregulating the expression of Bcl-2. Additionally, it was demonstrated that Cur may regulate collagen metabolism by decreasing the protein expression of matrix metalloproteinase (MMP)-1 and MMP-3, and may promote the repair of cells damaged as a result of UVA irradiation through increasing the protein expression of transforming growth factor-beta (TGF-beta) and Smad2/3, and decreasing the expression of the TGF-beta inhibitor, Smad7. In conclusion, the results of the present study indicate the potential benefits of Cur for the protection of HDFs against UVA-induced photoaging and highlight the potential for the application of Cur in skin photoprotection. PMID- 29568865 TI - Trifluoperazine induces apoptosis through the upregulation of Bax/Bcl-2 and downregulated phosphorylation of AKT in mesangial cells and improves renal function in lupus nephritis mice. AB - The inhibition of mesangial cell (MC) proliferation has become an important therapy in preventing glomerular proliferation diseases. Trifluoperazine (TFP) has been reported to inhibit the proliferation of several types of cancer cell, however, the effects of TFP in renal proliferation diseases remain to be fully elucidated. The present study examined the effects of TFP on the proliferation of MCs and quantified cell apoptosis progression in vivo and in vitro. The effects of various TFP concentrations and treatment durations on cell proliferation and cell apoptosis in vitro were analyzed using flow cytometry in conjunction with a Cell Counting kit-8 assay. Cell proliferation in vivo was determined using hematoxylin and eosin staining and immunohistochemistry of Ki67. The expression of the two cell apoptosis-related proteins, B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax), were estimated using western blot analysis and immunohistochemistry in vivo and in vitro. TFP-induced phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT) signaling pathways were also estimated using western blot analysis. These results suggested that TFP inhibited MC proliferation in a dose- and time-dependent manner. It was found that TFP inhibited the abnormal proliferation of MCs, which was stimulated by 20% fetal bovine serum in vitro and in lupus MRL/lpr mice. TFP promoted cell apoptosis, downregulated the expression of Bcl-2 and upregulated the expression of Bax in a dose-dependent manner at mRNA and protein levels. In addition, TFP inhibited phosphorylated AKT, potentially leading to the suppressed activation of PI3K/AKT signaling pathways. TFP treatment significantly decreased the levels of blood urea nitrogen and serum creatinine, but had no significant effects on the body weight and liver function of the lupus mice. These results validated and reinforced the potential of TFP in the treatment of mesangial proliferative diseases. PMID- 29568866 TI - Incorporation of CD40 ligand enhances the immunogenicity of tumor-associated calcium signal transducer 2 virus-like particles against lung cancer. AB - The cell surface glycoprotein Trop-2 is overexpressed in various types of cancer, including in lung cancer, and has recently been used as an effective immunotherapeutic target. CD40 ligand (CD40L), a tumor necrosis factor superfamily member, is a promising immune adjuvant. Human immunodeficiency virus (HIV) gag-based virus-like particles (VLPs) are highly immunogenic, and foreign antigens can be incorporated onto their membrane envelope for cancer vaccine development. In the present study, a HIV gag-based VLP strategy and Bac-to-Bac system were utilized to construct Trop-2, CD40L and gag recombinant baculoviruses, which were then used to infect TN5 cells in order to form Trop-2 VLPs or Trop-2-CD40L VLPs. These VLPs were characterized using transmission electron microscopy and western blot analysis methods. VLPs incorporating murine Trop-2 only or incorporating Trop-2 and CD40L were used to immunize C57BL/6 mice. Immunized mice demonstrated high humoral and cellular immunity responses, whereas the Trop-2-CD40L VLPs led to higher immune responses in comparison with Trop-2 only VLPs. Immunization with Trop-2-CD40L VLPs also reduced tumor growth more effectively compared with Trop-2 VLPs. Furthermore, Trop-2-CD40L VLP immunization increased the survival rate of Lewis tumor-bearing mice more significantly when compared with Trop-2 only VLPs. In conclusion, the present study provided a novel vaccine design by combination of a tumor antigen and an immune adjuvant based on a VLP strategy, which may be potentially applied as an alternative immunotherapeutic option in the treatment of lung cancer. PMID- 29568867 TI - miR-503 suppresses the proliferation and metastasis of esophageal squamous cell carcinoma by triggering autophagy via PKA/mTOR signaling. AB - MicroRNA (miR)-503 is involved in the regulation of the malignant phenotype in multiple tumor types, and has been proven to be a novel diagnostic and therapeutic target; however, its function and mechanisms of action have not yet been fully elucidated in esophageal squamous cell carcinoma (ESCC). In the current study, we detected miR-503 expression by RT-qPCR and found that miR-503 expression was increased in ESCC, but negatively correlated with lymph node metastasis, TNM stage and tumor differentiation. Functionally, we confirmed that miR-503 inhibited the proliferation and metastasis of ESCC cells by triggering cellular autophagy. Mechanistically, we confirmed that miR-503 exerted its biological effects by targeting protein kinase CAMP-activated catalytic subunit alpha (PRKACA) in ESCC by dual luciferase reporter assay. Moreover, miR-503 was found to trigger autophagy in ESCC cells through the protein kinase A (PKA)/mammalian target of rapamycin (mTOR) pathway. Taken together, our results demonstrate that miR-503 suppresses the proliferation and metastasis of ESCC via the activation of autophagy, mediated by the PKA/mTOR signaling pathway. PMID- 29568868 TI - Polo-like kinase 2 promotes chemoresistance and predicts limited survival benefit from adjuvant chemotherapy in colorectal cancer. AB - Colorectal cancer (CRC) is one of the most common malignances worldwide. Chemoresistance remains a major issue in the field of CRC treatment. The present study aimed to investigate the potential role of polo-like kinase 2 (Plk2) in chemoresistance in CRC. The associations between Plk2 and clinicopathological factors, as well as chemotherapeutic benefit were analyzed with a publicly available CRC dataset. The correlation between Plk2 expression and chemosensitivity was further confirmed in CRC cells. Moreover, knockdown and exogenous overexpression experiments of Plk2 were carried out to uncover the potential role of Plk2 in regulating the chemoresistance of CRC cells. We found that the expression of Plk2 was significantly associated with proximally located tumors. In addition, it was found that high expression ofPlk2 was associated with deficient mismatch repair status, B-raf serine/threonine kinase proto-oncogeneand Kirsten rat sarcoma viral oncogene homolog mutations. By contrast, tumor protein 53 mutation was correlated with a low expression level of Plk2. A higher expression level of Plk2 significantly predicted a poorer outcome in patients with CRC. However, the prognostic significance was only observed in patients who received adjuvant chemotherapy. In CRC cells, higher levels of Plk2 were associated with increased resistance to chemotherapeutic agents. Knocking down the expression of Plk2 resulted in elevated cellular apoptosis induced by oxaliplatin. By contrast, exogenous overexpression of Plk2 exerted an anti apoptotic effect and enhanced the resistance of CRC cells to chemotherapeutic agents. In conclusion, a high expression of Plk2 was associated with chemoresistant traits of CRC through inhibiting apoptosis. These results suggested that Plk2 may serve as a predictive marker for chemoresistance and a novel target in CRC treatment. PMID- 29568869 TI - Therapeutic effects of liver soothing pingchuan formula decoction on experimental asthma in BALB/c mice via regulation of nerve growth factor-tyrosine kinase A pathway. AB - The present study was designed to investigate the effects of liver soothing pingchuan formula decoction (LSPF) on experimental asthma in BALB/c mice and explore its potential molecular mechanisms. An animal model of asthma was established in BALB/c mice through sensitization and activation with intraperitoneal injection of 10% ovalbumin (OVA)/Al(OH)3 solution in addition to inhalation of a 5% OVA solution. LSPF (300 and 600 mg/kg/day) was initially administered orally prior to activation. Following this, bronchoalveolar lavage fluid (BALF) and lung tissues were collected for histopathalogical examination. Levels of inflammatory cells and cytokines were determined in the BALF, and levels of nerve growth factor (NGF) and tyrosine kinase A (TrkA) in the lung tissues were determined. The results of the present study indicated that increased inflammatory reactions were observed following OVA sensitization (P<0.05), and the expression levels of NGF (P<0.05) and TrkA (P<0.05) were significantly increased, compared with normal mice. Notably, compared with the asthma model group, immunohistochemical results revealed that LSPF treatment suppressed OVA induced inflammatory reactions (P<0.05) and NGF (P<0.05) and TrkA expression levels (P<0.05). In addition, the NGF (P<0.05) and TrkA (P<0.05) were revealed to be downregulated with LSPF treatment from the results of the ELISA and western blotting assay. Overall, the results of the present study demonstrated that LSPF exhibits therapeutic effects on experimental asthma in mice, via downregulation of the NGF-TrkA pathway. PMID- 29568870 TI - MicroRNA-599 targets high-mobility group AT-hook 2 to inhibit cell proliferation and invasion in clear cell renal carcinoma. AB - Dysregulation of microRNAs (miRNAs) is associated with the occurrence and development of clear cell renal cell carcinoma (ccRCC) through their participation in a number of critical biological processes. Therefore, an in depth investigation into miRNAs and their biological roles within ccRCC may provide useful insights and lead to the identification of novel therapeutic methods for patients with ccRCC. miRNA-599 (miR-599) serves critical roles in different types of human cancer. However, the expression pattern, biological function and molecular mechanism of miR-599 in ccRCC remain unknown. The present study aimed to detect the expression level of miR-599 in ccRCC, examine its effect on ccRCC progression and further explore the possible underlying mechanisms. It was observed that miR-599 was significantly underexpressed in ccRCC tissues and cell lines compared with the control. Functional assays revealed that restored expression of miR-599 restricted the proliferation and invasion of ccRCC cells. Bioinformatics analysis, luciferase reporter assay, reverse transcription-quantitative polymerase chain reaction and western blot analysis demonstrated that high-mobility group AT-hook 2 (HMGA2) was a direct target of miR-599 in ccRCC. HMGA2 knockdown simulated the suppressive effects caused by miR-599 overexpression in ccRCC. Recovered HMGA2 expression partially rescued the miR-599-mediated inhibition of ccRCC proliferation and invasion. These results suggest that miR-599 may serve tumour suppressive roles in ccRCC by directly targeting HMGA2, indicating that miR-599 may have potential as a treatment for patients with ccRCC. PMID- 29568871 TI - Involvement of multidrug resistance protein 4 in the hepatocyte efflux of lamivudine and entecavir. AB - Multidrug resistance protein 4 (MRP4) is capable of transporting acyclic nucleotide phosphonates, but little is known about its role in lamivudine (LAM) and entecavir (ETV) transport. In the present study, the involvement of MRP4 in the transport of LAM and ETV was investigated through in vitro experiments. The cytotoxicity of three antiviral drugs and their activities against HBV as characterized in HepG2.4D14 [wild-type hepatitis B virus (HBV)] and HepG2.A64 (ETV-resistant HBV) cells. LAM, ETV and tenofovir (TFV) demonstrated a 50% effective concentration against HBV of 4.14+/-0.03, 0.13+/-0.02 and 3.24+/-0.01 uM in HepG2.4D14 cells and of 5.94+/-0.20, 6.28+/-0.07 and 11.43+/-0.09 uM in HepG2.A64 cells, respectively. After administering 3-([(3-(2-[7-chloro-2 quinolinyl]ethyl)phenyl]-[(3-dimethylamino-3-oxoporphyl)-thio)-methyl]-thio) propanoic acid (MK571), the intracellular concentrations of all three drugs were much lower than the extracellular drug concentrations in these two cell types, whereas the intracellular drug concentrations in wild-type cells were higher than those in ETV-resistant cells. Furthermore, the intracellular levels of LAM, ETV and TFV were enhanced and the extracellular concentrations were reduced by addition of MK571. Thus, MRP4 is mainly responsible for the efflux of LAM and ETV in hepatocyte cultures. These results may contribute to enhancing antiviral efficacy. PMID- 29568872 TI - IL-10 inhibits retinal pigment epithelium cell proliferation and migration through regulation of VEGF in rhegmatogenous retinal detachment. AB - Rhegmatogenous retinal detachment (RRD) is a disorder of the eye that affects physical and mental health. Retinal pigment epithelium (RPE) is closely associated with RRD, and it is hypothesized that RPE-secreted inflammatory cytokines may induce early pathological changes of RRD and may participate in RPE proliferation and migration. The present study determined a role for interleukin (IL)-10 as an RPE-secreted immune regulatory factor that contributes to RRD. A rat RRD model was established and RPE cells were isolated and cultivated. RPE cells were randomly divided into four groups, three treated with different concentrations of IL-10 (100, 50, and 20 mM) and one untreated. RPE cell proliferation was evaluated by MTT assay and the activity of caspase-3 was also measured. RPE cell invasion was determined by Transwell assay. Vascular endothelial growth factor A (VEGF) expression was examined by reverse transcription-quantitative polymerase chain reaction and western blotting; IL-1 and IL-6 levels were measured by ELISA. IL-10 treatment suppressed RPE cell proliferation and migration, promoted caspase-3 activity, inhibited VEGF mRNA and protein expression, and downregulated the secretion of inflammatory cytokines IL 1 and IL-6 in RRD group compared with the untreated Model group. The aforementioned effects of IL-10 became more evident with increasing IL-10 concentration. IL-10 suppressed inflammation, facilitated RPE cell apoptosis and inhibited cell proliferation and migration through the regulation of VEGF expression. PMID- 29568873 TI - The deficiency of CX3CL1/CX3CR1 system ameliorates high fructose diet-induced kidney injury by regulating NF-kappaB pathways in CX3CR1-knock out mice. AB - Fructose, the most important functional food additive from the last century, has been widely used in industry, agriculture, light industry, food and medicine. With the improvement of people's living standard and economic level, excess intake of fructose results in metabolic symptoms, including hyperleptinemia, insulin resistance and neuroinflammation is causing high risk of chronic kidney disease development in humans and animals. However, the underlying molecular mechanism of renal injury is still not fully understood, and the development of effective drugs and treatments are delayed. Hence, we investigated the role of crosstalk of CX3CL1-CX3CR1 axis and nuclear factor-kappaB (NF-kappaB) signaling pathway in the development of renal injury. CX3CL1-knock-out C57BL/6 mice were constructed and used to analyze the influence of CX3CL1-related signaling pathways on kidney injury of wild-type (WT) mice and CXECR1 deficiency mice, which were administrated with 30% fructose water. Western blotting, quantitative RT-PCR (qRT-PCR), immunohistochemistry, ELISA, flow cytometry and biochemical indicator analysis were used to determine the levels of renal injury and key signaling pathway associated with renal damage. The results indicated that administration of high fructose intake can cause typical renal inflammatory responses in serum and tissues. Fructose enhances the CX3CL1-CX3CR1 axis and NF kappaB activation, and promotes crosstalk of CX3CL1-CX3CR1 and NF-kappaB pathways. The phosphorylated AKT could be significantly activated in fructose induced renal injury via CX3CL1-CX3CR1 axis. CX3CR1 expression between WT and CX3CR1-/- mice were evaluated to establish their relationship with injury. Our results indicated that CX3CR1 may be the central and major indicator in the process of renal injury, which mediate AKT pathway and further enhance the NF kappaB activation. These findings demonstrated that crosstalk of CX3CL1-CX3CR1 axis and NF-kappaB signaling pathway play a direct role in fructose-induced kidney injury. Inhibition of CX3CL1-CX3CR1 pathway may suppress renal-related diseases. It may be a potential treatment choice for the clinical diagnoses and treatment in the future. PMID- 29568874 TI - Silencing of ASPP2 promotes the proliferation, migration and invasion of triple negative breast cancer cells via the PI3K/AKT pathway. AB - Apoptosis-stimulating p53 protein 2 (ASPP2) is an apoptosis inducer that acts via binding with p53 and then enhancing the transcriptional activities toward pro apoptosis genes. ASPP2 has recently been reported to serve a major role in p53 independent pathways. Triple-negative breast cancer (TNBC) is a type of breast cancer that is more aggressive and highly lethal when p53 is mutated. In the present study, the mRNA level of ASPP2 was found to be suppressed in breast tumors compared with that in adjacent normal breast tissues, and the expression of ASPP2 was also decreased in a series of breast cancer cell lines compared with that in MCF-10A normal breast cells. Downregulation of ASPP2 by specific small interfering RNA (siRNA) transfection was able to promote cell growth, reduce cell apoptosis, and contribute to cell migration and invasion. Furthermore, downregulation of ASPP2 promoted cell epithelial-mesenchymal transition (EMT) in MDA-MB-231 and HCC-1937 TNBC cells. Furthermore, it was found that when ASPP2 siRNA was transfected into MDA-MB-231 and HCC-1937 cells, the expression of phosphoinositide-3-kinase regulatory subunit 1 (p85alpha) decreased and phosphorylation of protein kinase B (AKT) increased, which are key molecular regulators in the phosphatidylinositol 3-kinase (PI3K)/AKT pathway. In conclusion, the present data indicated that ASPP2 had a crucial influence on the proliferation and metastasis in TNBC, and that the functional mechanism may be p53-independent to a great extent. ASPP2 and its link with the PI3K/AKT pathway deserve further investigation and may provide novel insights into therapeutic targets for TNBC. PMID- 29568875 TI - Expression of Rv2031c-Rv2626c fusion protein in Mycobacterium smegmatis enhances bacillary survival and modulates innate immunity in macrophages. AB - Dormancy-associated antigens encoded by the dormancy survival regulon (DosR) genes are required for survival of Mycobacterium tuberculosis (Mtb) in macrophages. However, mechanisms underlying survival of Mtb in macrophages remains to be elucidated. A recombinant Mycobacterium smegmatis strain (rMs) expressing a fusion protein of two dormancy-associated antigens Rv2031c and Rv2626c from Mtb was constructed in the present study. In an in vitro culture, growth rate of rMs was lower compared with Ms. A total of 24 h following infection of murine macrophages with rMs or Ms, percentage of viable cells decreased and the number of bacteria in viable cells increased compared with Ms, demonstrating that virulence and intracellular survival of rMs were enhanced. Compared with macrophages infected with Ms, necrosis of macrophages infected with rMs was increased, while apoptosis was inhibited. Macrophages infected with rMs secreted more interferon-gamma and interleukin-6, but fewer nitric oxide and tumor necrosis factor-alpha, compared with macrophages infected with Ms. The present study demonstrated that the fusion protein composed of dormancy associated antigens Rv2031c and Rv2626c in Ms serves a physiological function of a dormancy-associated antigen and modulates innate immunity of host macrophages, therefore favoring intracellular bacillary survival. PMID- 29568876 TI - Fisetin administration improves LPS-induced acute otitis media in mouse in vivo. AB - Acute otitis media is one of the most common infectious diseases worldwide in spite of the widespread vaccination. The present study was conducted to explore the effects of fisetin on mouse acute otitis media models. The animal models were established by lipopolysaccharide (LPS) injection into the middle ear of mice via the tympanic membrane. Fisetin was administered to mice for ten days through intragastric administration immediate after LPS application. Hematoxylin and eosin (H&E) staining was performed and the pro-inflammatory cytokines, including interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha), IL-6 and VEGF, were measured through enzyme-linked immunosorbent assay (ELISA) method and RT-qPCR analysis. Toll-like receptor 4 (TLR4)/nuclear factor-kappaB (NF-kappaB) signaling pathway was detected by immunoblotting assays. Reactive oxygen species (ROS) generated levels were determined through assessment of anti-oxidants, and TXNIP/MAPKs signaling pathways were explored to reveal the possible molecular mechanism for acute otitis media progression and the function of fisetin. Fisetin reduced mucosal thickness caused by LPS. In fisetin-treated animals, pro inflammatory cytokine release was downregulated accompanied with TLR4/NF-kappaB inactivation. ROS production was significantly decreased in comparison to the LPS treated group. The TXNIP/MAPKs signaling pathway was inactivated for fisetin treatment in LPS-induced mice with acute otitis media. The above results indicated that fisetin improved acute otitis media through inflammation and ROS suppression via inactivating TLR4/NF-kappaB and TXNIP/MAPKs signaling pathways. PMID- 29568877 TI - MicroRNA-22 inhibits the proliferation and migration, and increases the cisplatin sensitivity, of osteosarcoma cells. AB - Osteosarcoma (OS) is the major type of primary bone tumor and is associated with a poor prognosis due to chemotherapy resistance. Accumulating evidence indicates that microRNAs (miRNAs/miRs) may influence the tumor progression of OS and cell sensitivity to chemotherapy. In the present study, a total of 7 patients with OS and 7 healthy volunteers were recruited. Reverse transcription-quantitative polymerase chain reaction and ELISA were performed to determine the expression of miRNAs and mRNAs in the serum of participants. Furthermore, the biological function of miR-22 and S100A11 was examined in MG-63 cells using Cell Counting Kit-8 assays, Transwell migration assays and western blot analysis to determine the effects on cell proliferation, migration and protein expression, respectively, while MG-63 cell sensitivity to cisplatin was assessed by measuring cell viability following cisplatin treatment and calculating the half maximal inhibitory concentration (IC50). Additionally, the association between miR-22 and S100 calcium-binding protein A11 (S100A11) was validated using a luciferase reporter assay. The results demonstrated that miR-22 expression was significantly reduced in patients with OS and the MG-63 OS cell line, compared with healthy volunteers and the normal osteoblast hFOB 1.19 cell line, respectively, while the expression of S100A11 was negatively associated with miR-22 levels in the MG-63 cell line. Furthermore, overexpression of miR-22 inhibited the proliferation and migratory ability of MG-63 cells, and increased the sensitivity of MG-63 cells to cisplatin treatment; however, overexpression of S100A11 partially attenuated the alterations in proliferation, migratory ability and chemosensitivity that were induced by miR-22 overexpression. In addition, it was confirmed that S100A11 is a direct target gene of miR-22 in MG-63 cells. In conclusion, to the best of our knowledge, the present study is the first to demonstrate that miR-22 may be a promising therapeutic target and may have potential as part of a combination treatment alongside chemotherapeutic agents for OS. PMID- 29568878 TI - Hypoxia induces endothelial-mesenchymal transition in pulmonary vascular remodeling. AB - It is well established that hypoxia induces epithelial-mesenchymal transition in vitro and in vivo. However, the role of hypoxia in endothelial-mesenchymal transition (EndMT), an important process in the pathogenesis of pulmonary hypertension, is not well-characterized. The present study demonstrated a significant downregulation of the endothelial marker CD31 and its co-localization with a mesenchymal marker, alpha-smooth muscle actin (alpha-SMA), in the intimal layer of small pulmonary arteries of rats exposed to chronic hypoxia. These results suggest a possible role of hypoxia in inducing EndMT in vivo. Consistent with these observations, pulmonary microvascular endothelial cells (PMVECs) cultured under hypoxic conditions exhibited a significant decrease in CD31 expression, alongside a marked increase in the expression of alpha-SMA and two other mesenchymal markers, collagen (Col) 1A1 and Col3A1. In addition, hypoxia promoted the proliferation and migration of alpha-SMA-expressing mesenchymal-like cells, but not of PMVECs. Of note, knockdown of hypoxia-inducible factor 1alpha (HIF-1alpha) effectively inhibited hypoxic induction of alpha-SMA, Col1A1 and the transcription factor Twist1, while rescuing hypoxic suppression of CD31; these results suggest that HIF-1alpha is essential for hypoxia-induced EndMT and that it serves as an upstream regulator of Twist1. Mechanistically, HIF-1alpha was identified to bind to the promoter of the Twist1 gene, thus activating Twist1 transcription and regulating EndMT. Collectively, the present results indicate that the HIF-1alpha/Twist1 pathway has a critical role in mediating the effect of hypoxia-induced EndMT in pulmonary arterial remodeling. PMID- 29568879 TI - Retinal ganglion cell-conditioned medium and surrounding pressure alters gene expression and differentiation of rat retinal progenitor cells. AB - Loss of retinal ganglion cells is implicated in glaucoma and high intraocular pressure. Factors that affect the differentiation of retinal progenitor cells into retinal ganglion cells remain unclear. The present study aimed to investigate the effects of retinal ganglion cell-conditioned medium on gene expression and differentiation in retinal progenitor cells, and the effects of surrounding pressure on the survival and differentiation of retinal progenitor cells. Retinal progenitor cells and retinal ganglion cells were isolated from rats. Immunofluorescence staining of Nestin and Thy1 was performed to identify rat retinal progenitor cells and retinal ganglion cells, respectively. Retinal progenitor cells and ganglion cells were cultured for 48 h under surrounding pressure of 0, 20, 40, 60 and 80 mmHg. Cellular apoptosis was detected using a caspase-3 assay kit. In addition, the culture supernatant of rat retinal ganglion cells was collected. Retinal progenitor cells were cultured in the presence or absence of retinal ganglion-conditioned medium for 72 h under normal pressure. Gene expression of Nestin, paired box protein 6 (PAX6), Thy1 and brain-specific homeobox/POU domain protein 3 (Brn-3) in retinal progenitor cells was detected by reverse transcription-quantitative polymerase chain reaction. Retinal progenitor cells were cultured in retinal ganglion-conditioned medium for 72 h under surrounding pressure of 0 and 40 mmHg, respectively, and flow cytometry was utilized to evaluate the effects of pressure on the differentiation of retinal progenitor cells into retinal ganglion cells. The results demonstrated that isolated retinal progenitor cells were Nestin-positive and retinal ganglion cells were Thy1-positive, suggesting successful isolation. The activity of caspase-3 increased in retinal progenitor cells and retinal ganglion cells in a pressure dependent manner. When the surrounding pressure reached 40, 60 and 80 mmHg, the activity of caspase-3 in retinal progenitor cells and ganglion cells increased significantly compared with cells that were not under pressure. Compared with retinal progenitor cells cultured without ganglion-conditioned medium, those cultured with ganglion-conditioned medium had significantly decreased expression levels of Nestin and PAX6, and increased expression levels of Thy1 and Brn3. Compared with 0 mmHg pressure, retinal progenitor cells cultured in ganglion conditioned medium under 40 mmHg pressure had increased percentages of Thy1 positive cells. In conclusion, the apoptosis of rat retinal progenitor cells and retinal ganglion cells was pressure-dependent. Retinal ganglion cell-conditioned medium increased the differentiation of retinal progenitor cells into retinal ganglion-like cells, and the differentiation increased as surrounding pressure increased. Current study provides insights that may contribute to the efforts of developing a treatment for glaucoma. PMID- 29568880 TI - Simvastatin induces apoptosis in PTEN-haploinsufficient lipoma cells. AB - Adipose tissue tumors (lipomas) frequently develop in patients with heterozygous germ line phosphatase and tensin homolog (PTEN) mutations. simvastatin has been demonstrated to exhibit antitumor effects, and so the aim of the present study was to assess the effects of simvastatin on the growth of human PTEN haploinsufficient lipoma cells. Whether the effects of simvastatin in lipomas are mediated via PTEN upregulation was also assessed. The results of the present study revealed that simvastatin treatment reduced cell viability and induced apoptosis in human lipoma cells. Furthermore, it was demonstrated that the expression of cellular PTEN mRNA and protein was increased following simvastatin stimulation. In addition, the phosphorylation of protein kinase B and downstream targets of mammalian target of rapamycin and 4E-binding protein (4E-BP)-1 was attenuated. It was also demonstrated that simvastatin induced PTEN transcriptional upregulation by increasing peroxisome proliferator-activated receptor (PPAR)gamma expression. The small interfering RNA-mediated knockdown of PPARgamma abrogated the stimulatory effect of simvastatin on the PTEN protein, but did not influence apoptosis. The results of the present study suggest that simvastatin may be beneficial for patients with inoperable PTEN haploinsufficient lipomas. PMID- 29568881 TI - Liraglutide improves hepatic insulin resistance via the canonical Wnt signaling pathway. AB - Liraglutide, a modified form of glucagon-like peptide-1 (GLP-1), is used in the treatment of diabetes mellitus. However, the underlying mechanism by which liraglutide improves liver insulin resistance remains to be elucidated. The proto oncogene Wnt (Wnt) signaling pathway has been reported to be associated with glucose and lipid metabolism. Using in vivo and in vitro models of diabetes and insulin resistance, it was investigated whether the beneficial effects of liraglutide on liver glucose metabolism are mediated by the Wnt signaling pathway. The results of the present study demonstrate that body weight, fasting blood glucose, insulin levels and the homeostasis model assessment for insulin resistance were markedly decreased in db/db mice treated with liraglutide compared with control mice. Liraglutide also improved liver morphology and reduced the accumulation of lipid droplets. Furthermore, the expression of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase was downregulated, whereas the expression of phosphorylated forkhead box O1, Wnt signaling pathway associated molecules, beta-catenin, transcription factor 7-like 2 and phosphorylated glycogen synthase kinase-3beta was upregulated in the liver of mice treated with liraglutide. In the in vitro study, increased gluconeogenesis and decreased glucose uptake rates were observed in insulin resistant hepatocytes; treatment with liraglutide significantly reversed this effect. Furthermore, transfection of insulin resistant hepatocytes with beta-catenin small interfering RNA attenuated the effects of liraglutide, suggesting that liraglutide improves insulin resistance via activating the beta-catenin/Wnt signaling pathway. The results of the present study suggest a novel mechanism underlying liraglutide-mediated improvements in insulin resistance in the liver. The Wnt signaling pathway may be a potential therapeutic target for the treatment of altered hepatic physiology in insulin resistance. PMID- 29568882 TI - Long non-coding RNAs RP5-821D11.7, APCDD1L-AS1 and RP11-277P12.9 were associated with the prognosis of lung squamous cell carcinoma. AB - Lung squamous cell carcinoma (LUSC), a type of non-small cell lung carcinoma, has a poor therapeutic response, high relapse rate and poor prognosis. The present study was designed to reveal the key long non-coding RNAs (lncRNAs) associated with the prognosis of LUSC. The lncRNA expression profiles of LUSC and adjacent samples were downloaded from The Cancer Genome Atlas database. Based on the edgeR and DEseq packages, the differentially expressed lncRNAs (DELs) between LUSC and adjacent samples were obtained and the intersecting DELs were regarded as significant DELs. Subsequently, a prognostic risk model was established using Cox regression analysis and its classification effect was detected by survival analysis. Using survival analysis, the effect of the prognostic risk model was assessed in the validation set and other types of cancer. Finally, the co expression genes of key lncRNAs were screened using the Multi-Experiment Matrix tool and the STRING database, and their functions were predicted via enrichment analysis using the Database for Annotation, Visualization and Integrated Discovery tool. A total of 2,041 significant DELs between LUSC and adjacent samples were screened. The prognostic risk model consisting of RP5-821D11.7, APCDD1L-AS1 and RP11-277P12.9 was established, which had a good classification effect. Cox multivariate regression analysis demonstrated that risk score may serve as an independent prognostic factor. Furthermore, certain co-expression genes of RP5-821D11.7 (including proliferating cell nuclear antigen), APCDD1L-AS1 (including semaphorin 5A, semaphorin 6D, ADAMTS like 1, ADAM metallopeptidase with thrombospondin type 1 motif 6, slit guidance ligand 3, and tenascin C) and RP11-277P12.9 (including Wnt family member 2B) were identified. Additionally, 'positive regulation of cell migration' and 'proteinaceous extracellular matrix' were enriched. In conclusion, the expression levels of the lncRNAs RP5-821D11.7, APCDD1L-AS1 and RP11-277P12.9 may affect the prognosis of LUSC. PMID- 29568884 TI - Silencing of aquaporin 5 inhibits the growth of A549 lung cancer cells in vitro and in vivo. AB - The water channel protein aquaporin 5 (AQP5) is highly expressed in numerous tumors. However, its expression pattern and functions in lung cancer in humans remain unknown. In the present study, the role of AQP5 in the development of lung malignancies was examined. A short hairpin RNA construct targeting AQP5 mRNA was transfected into A549 cells to generate a lung cancer cell line in which AQP5 expression was stably silenced. In vitro and in vivo experiments were then performed to establish the effects of AQP5 on A549 cell apoptosis, proliferation and cell cycle progression. The results demonstrated that AQP5 silencing significantly inhibited the proliferation and promoted the apoptosis of A549 lung cancer cells in vitro and in vivo. In addition, it resulted in decreased activation of the extracellular signal-regulated kinase 1/2 signaling pathway in A549 cells, and reduced levels of the downstream proteins c-Fos and phosphorylated cAMP response element-binding protein. Furthermore, inhibition of AQP5 expression effectively reduced the tumorigenicity of A549 cells in vivo. In conclusion, silencing of AQP5 suppressed the growth of A549 cells in vitro and in vivo, suggesting that it may serve as a therapeutic target in lung cancer. PMID- 29568883 TI - Everolimus inhibits breast cancer cell growth through PI3K/AKT/mTOR signaling pathway. AB - Breast cancer is one of the most prevalent malignancies and the leading cause of cancer-associated mortality in women worldwide and in China. Everolimus (C53H83NO14) is an efficient anti-cancer drug for breast cancer which targets mammalian target of rapamycin (mTOR). The present study investigated the inhibitory effects of everolimus on breast cancer cells and an MCF-7-bearing mouse model. The potential mechanism of the everolimus-mediated decrease in growth and aggressiveness of breast cancer cells was reported. Results demonstrated that everolimus significantly inhibited breast cancer cell growth, migration and invasion. It was demonstrated that everolimus induced apoptosis through decreasing B cell lymphoma (Bcl)-2 and Bcl-w and increasing caspase-3 and caspase-8 expression levels in breast cancer cells. It was observed that everolimus decreased phosphoinositide 3-kinase (PI3K), protein kinase B (AKT) and mTOR expression levels in breast cancer cells. Results additionally demonstrated that PI3 K overexpression prevented that everolimus-mediated inhibition of growth and aggressiveness in MCF-7 cells. In vivo assays demonstrated that everolimus treatment markedly inhibited tumor growth in the MCF-7 bearing mouse model. Overall, these data indicate that everolimus inhibits growth and aggressiveness of breast cancer cells through the PI3K/AKT/mTOR signaling pathways, suggesting the PI3K/AKT/mTOR signaling pathway may act as a therapeutic target for the treatment of human cancer. PMID- 29568885 TI - Role of leptin and the leptin receptor in the pathogenesis of varicocele-induced testicular dysfunction. AB - The present study investigated the expression of leptin and its receptor in the left testis and hypothalamus of rats with varicocele and clarified their roles in the pathogenesis of varicocele-induced testicular dysfunction. A total of 40 male rats were divided randomly into four groups. Groups 1 (G1) and 3 (G3) underwent a sham operation. Groups 2 (G2) and 4 (G4) underwent operations to form a varicocele created by partial ligation of the left renal vein. G1 and G2 rats were euthanized 4 weeks after the operation while G3 and G4 rats were euthanized at 8 weeks. The expression of leptin and its receptor was analyzed by immunohistochemistry. The mRNA levels of leptin, its receptor, kisspeptin (KiSS 1), G-protein coupled receptor 54 (GPR54), gonadotropin releasing hormone (GnRH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were measured by reverse transcription-quantitative polymerase chain reaction. Testicular spermatogenesis function and gonadal hormone levels were measured. Compared with G1 and G3, the expression of leptin and its receptor in rat testis was significantly higher in G2 and G4, respectively. Leptin expression was inversely associated with the number of sperm in the left epididymis, thickness of the seminiferous epithelium and the diameter of seminiferous tubules. The expression of leptin receptors in the hypothalamus of G2 and G4 was significantly increased compared with that in G1 and G3, respectively. The mRNA levels of KiSS-1, GPR54, GnRH, LH and FSH in G2 and G4 were significantly increased compared with that in G1 and G3, respectively. Serum testosterone levels in G2 and G4 rats were significantly lower than those in G1 and G3 rats, respectively. There was no significant difference between the serum levels of FSH, LH and leptin. These results suggest that leptin and its receptor may serve significant roles in the pathogenesis of varicocele-induced testicular dysfunction.

PMID- 29568887 TI - Genome-wide analysis of DNA methylation in human peripheral leukocytes identifies potential biomarkers of nonalcoholic fatty liver disease. AB - The aim of the present study was to uncover the role of leukocytic DNA methylation in the evaluation of nonalcoholic fatty liver disease (NAFLD). Patients with biopsy-proven NAFLD (n=35) and normal controls (n=30) were recruited from Chinese Han population. Their DNA methylation in peripheral leukocytes was subjected to genome-wide profiling. The association between differential methylation of CpG sites and NAFLD was further investigated on the basis of histopathological classification, bioinformatics, and pyrosequencing. A panel of 863 differentially methylated CpG sites dominated by global hypomethylation, characterized the NAFLD patients. Hypomethylated CpG sites of Acyl-CoA synthetase long-chain family member 4 (ACSL4) (cg15536552) and carnitine palmitoyltransferase 1C (CPT1C) (cg21604803) associated with the increased risk of NAFLD [cg15536552, odds ratio (OR): 11.44, 95% confidence interval (CI): 1.04 125.37, P=0.046; cg21604803, OR: 6.57, 95% CI: 1.02-42.15, P=0.047] at cut-off beta-values of <3.36 (ACSL4 cg15536552) and <3.54 (CPT1C cg21604803), respectively, after the adjustment of age, sex, body mass index (BMI) and homeostasis model assessment of insulin resistant (HOMA-IR). Their methylation levels also served as biomarkers of NAFLD (ACSL4 cg15536552, AUC: 0.80, 95% CI: 0.62-0.98, P=0.009; CPT1C cg21604803, AUC: 0.78, 95% CI: 0.65-0.91, P=0.001). Pathologically, lowered methylation level (beta-values <3.26) of ACSL4 (cg15536552) conferred susceptibility to nonalcoholic steatohepatitis (NASH). Taken together, genome-wide hypomethylation of peripheral leukocytes may differentiate NAFLD patients from normal controls. The leukocytic hypomethylated ACSL4 (cg15536552) was suggested to be a biomarker for the pathological characteristics of NAFLD. PMID- 29568888 TI - Effects of Bushen-Yizhi formula on age-related inflammation and oxidative stress in senescence-accelerated mice. AB - The present study aimed to investigate the possible effects and underlying molecular mechanism of Bushen-Yizhi formula (BSYZ), a traditional Chinese medicine, on age-related degeneration of brain physiology in senescence accelerated mouse prone 8 (SAMP8) mice. SAMP8 mice (age, 6 months) were administered BSYZ (1.46, 2.92 and 5.84 g/kg/day) for 30 days. Morris water maze and step-down tests demonstrated that BSYZ significantly improved memory impairments in SAMP8 mice. In addition, BSYZ significantly enhanced the expression levels of peroxisome proliferator-activated receptor-gamma and B-cell lymphoma extra-large, and downregulated the expression levels of inflammatory mediators, glial fibrillary acidic protein, cyclooxygenase-2, nuclear factor kappaB and interleukin-1beta in the brain compared with untreated SAMP8 mice. Furthermore, BSYZ reversed disordered superoxide dismutase activity, malondialdehyde content and glutathione peroxidase activity, and ameliorated apoptosis and histological alterations. The present study indicated that BSYZ may attenuate cognitive impairment in SAMP8 mice, and modulate inflammation, oxidative stress and neuronal apoptosis. These results suggested that BSYZ may have the potential to be further developed into a therapeutic agent for protection against age-related neurodegenerative diseases. PMID- 29568889 TI - Treatment of experimental autoimmune myasthenia gravis rats with FTY720 and its effect on Th1/Th2 cells. AB - Myasthenia gravis (MG) is an autoimmune neurological disease that is characterized by the expression of anti-acetylcholine receptor (AChR) antibodies. The immune response at AChRs of neuromuscular junction is disrupted in patients with MG, which manifests as skeletal muscle fatigue and is aggravated following periods of activity and alleviated following rest. Although a novel immune suppressant FTY720 drug, which exhibits strong immune suppression efficacy and minor adverse effects, is available, its role and mechanism in MG have not been elucidated. The aim of this study was to investigate the role of FTY720 in MG. A total of 60 healthy female Lewis rats were randomly assigned into 4 groups: Control group, Model group of experimental autoimmune myasthenia gravis (EAMG), 0.5 mg/kg FTY720-treatment EAMG group and 1.0 mg/kg FTY720-treatment EAMG group. Body weight and symptoms were examined; Lennon score was used to evaluate improvement of clinical symptoms. Reverse transcription-quantitative polymerase chain reaction and ELISA were used to test the mRNA and protein expression levels, respectively, of the helper T (Th)1 and Th2 cell cytokines, including interleukin (IL)-2, interferon (IFN)-gamma, IL-4 and IL-6 in thymus tissue and serum. FTY720 treatment improved rat MG symptoms, increased body weight and decreased Lennon score. FTY720 treatments also reduced tissue and serum levels of IL-2, IFN-gamma and IL-6, but not IL-4 expression levels. FTY720 suppressed the inflammatory response and improved EAMG symptoms by inhibiting the secretion of inflammatory factors. PMID- 29568890 TI - miR-19a/b and MeCP2 repress reciprocally to regulate multidrug resistance in gastric cancer cells. AB - Despite the improvement in gastric cancer (GC) treatment, multidrug resistance (MDR) is still a significant reason for chemotherapy failure. Our previous studies have demonstrated that miR-19a/b upregulation directly promoted MDR in GC cells. However, the exact regulation and the potential molecule mechanisms have not been fully clarified. In this study, we found that miR-19a/b was directly involved in 5-aza-2'-deoxycytidine (5-Aza-dC) induced MDR of GC cells. Mechanically, demethylation of miR-19a/b repressed methyl CpG binding protein 2 (MeCP2) expression via direct binding at the 3'-untranslated regions, which then alleviated the inhibitory effects of MeCP2 on miR-19a/b expression. Thus, the mutual regulatory network sustains preservation of the expression levels of miR 19a/b. We further demonstrated that miR-19a/b expression was inversely correlated to MeCP2 expression in GC tissues. These data showed an intimate interplay among miR-19a/b methylation, MeCP2 activity, and MDR, revealing a potential therapeutic target for GC. PMID- 29568891 TI - Tissue expression of Toll-like receptors 2, 3, 4 and 7 in swine in response to the Shimen strain of classical swine fever virus. AB - The Toll-like receptors (TLRs) of the innate immune system provide the host with the ability to detect and respond to viral infections. The present study aimed to investigate the mRNA and protein expression levels of TLR2, 3, 4 and 7 in porcine tissues upon infection with the highly virulent Shimen strain of classical swine fever virus (CSFV). Reverse transcription-quantitative polymerase chain reaction was used to detect the mRNA expression levels of CSFV and TLR, whereas western blotting was used to detect the expression levels of TLR proteins. In addition, tissues underwent histological examination and immunohistochemistry to reveal the histopathological alterations associated with highly virulent CSFV infection and to detect TLR antigens. Furthermore, porcine monocyte-derived macrophages (pMDMs) were prestimulated with peptidoglycan from Staphylococcus aureus (PGN-SA), polyinosinic-polycytidylic acid [poly (I:C)], lipopolysaccharide from Escherichia coli 055:B5 (LPS-B5) or imiquimod (R837) in order to analyze the association between TLR expression and CSFV replication. Following stimulation for 12 h (with TLR-specific ligands), cells were infected with CSFV Shimen strain. The results revealed that the expression levels of TLR2 and TLR4 were increased in the lung and kidney, but were decreased in the spleen and lymph nodes in response to CSFV. TLR3 was strongly expressed in the heart and slightly upregulated in the spleen in response to CSFV Shimen strain infection, and TLR7 was increased in all examined tissues in the presence of CSFV. Furthermore, R837 and LPS-B5 exerted inhibitory effects on CSFV replication in pMDMs, whereas PGN-SA and poly(I:C) had no significant effect. These findings highlight the potential role of TLR expression in the context of CSFV infection. PMID- 29568892 TI - Effect of electro-acupuncture on the BDNF-TrkB pathway in the spinal cord of CCI rats. AB - Microglia, which comprise a sensor for pathological events in the central nervous system, may be triggered by nerve injury and transformed from a quiescent state into an activated state; ionised calcium binding adaptor molecule 1 (Iba1) is a sensitive marker associated with activated microglia. Accumulated evidence suggests that spinal activated microglia and the brain-derived neurotrophic factor (BDNF)-tyrosine kinase receptor B (TrkB) signalling pathway play major roles in the production and development of neuropathic pain. Electro-acupuncture (EA) has a positive effect on relieving chronic neuropathic pain; however, the underlying mechanisms remain unclear. To determine the significance of EA in the treatment of neuropathic pain mediated by activated microglia and the BDNF-TrkB signalling pathway in the spinal cord, the mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) values were recorded to assess hyperalgesia and allodynia. In addition, the amount of activated microglia and BDNF were assessed via immunofluorescence. Iba1, BDNF and TrkB mRNA expression levels were examined using qPCR; the protein levels of BDNF, p-TrkB and TrkB in the spinal cord were analysed via western blotting. The present study demonstrated that EA treatment increased the MWT and TWL values. EA significantly inhibited the proportion of activated microglia and BDNF expression in the spinal cord after chronic constrictive injury (CCI). Furthermore, EA decreased the expression of BDNF and TrkB at both the mRNA and protein levels in the spinal cord of CCI rats. These findings suggest that the analgesic effect of EA may be achieved by inhibiting the activation of spinal microglia and subsequently blocking the BDNF TrkB signalling pathway. PMID- 29568893 TI - KCC2-GABAA pathway correlates with the analgesic effect of electro-acupuncture in CCI rats. AB - Potassium-chloride cotransporter 2 (KCC2) has been indicated to serve a crucial role during chronic neuropathic pain (NP). Following the emergence of NP, gamma aminobutyric acid (GABA) A receptor-mediated signaling may be further impaired by the changes of KCC2 chloride anion gradient. In the present study, the authors investigate the effect of electro-acupuncture (EA) on the behavior and the expression of KCC2 and GABAA receptor gamma2 subunit in the spinal cord of chronic constriction injury (CCI) model rats. A total of 60 adult male Sprague Dawley rats were divided into four groups: Normal group, sham-CCI group, CCI group and CCI+EA group. The effect of EA was assessed via the values of mechanical withdrawal threshold and thermal withdrawal latency, which were significantly improved upon stimulation of the ST-36 and GB-34 acupoints. In addition, a marked reduction in both the mRNA and protein levels of KCC2 and GABAA receptor gamma2 subunit was observed in the spinal cord following loose ligation of the sciatic nerve. The reductions in KCC2 and GABAA receptor gamma2 subunit expression were reversed by EA treatment. These results support the notion that KCC2 and GABAA receptor gamma2 subunit contribute to NP following peripheral nerve injury and extend the understanding of the analgesic effects of EA on NP. PMID- 29568894 TI - Overexpression of satellite alpha transcripts leads to chromosomal instability via segregation errors at specific chromosomes. AB - The impairment of the stability of the chromosomal structure facilitates the abnormal segregation of chromosomes, thus increasing the risk of carcinogenesis. Chromosomal stability during segregation is managed by appropriate methylation at the centromere of chromosomes. Insufficient methylation, or hypomethylation, results in chromosomal instability. The centromere consists of satellite alpha repetitive sequences, which are ideal targets for DNA hypomethylation, resulting in the overexpression of satellite alpha transcript (SAT). The overexpression of SAT has been reported to induce the abnormal segregation of chromosomes. In this study, we verified the oncogenic pathway via chromosomal instability involving DNA hypomethylation and the overexpression of SAT. For this purpose, we constructed lentiviral vectors expressing SAT and control viruses and then infected human mammary epithelial cells with these vectors. The copy number alterations and segregation errors of chromosomes were evaluated by microarray based comparative genomic hybridization (array CGH) and immunocytochemistry, respectively. The levels of hypomethylation of satellite alpha sequences were determined by MethyLight polymerase chain reaction. Clinical specimens from 45 patients with breast cancer were recruited to verify the data in vitro. The results of immunocytochemistry revealed that the incidence of segregation errors was significantly higher in the cells overexpressing SAT than in the controls. An array CGH identified the specific chromosomes of 8q and 20q as frequent sites of copy number alterations in cells with SAT overexpression, although no such sites were noted in the controls, which was consistent with the data from clinical specimens. A regression analysis revealed that the expression of SAT was significantly associated with the levels of hypomethylation of satellite alpha sequences. On the whole, the overexpression of SAT led to chromosomal instability via segregation errors at specific chromosomes in connection with DNA hypomethylation, which was also recognized in clinical specimens of patients with breast cancer. Thus, this oncogenic pathway may be involved in the development of breast cancer. PMID- 29568895 TI - Abnormal expression of fibrosis markers, estrogen receptor alpha and stromal derived factor-1/chemokine (C-X-C motif) receptor-4 axis in intrauterine adhesions. AB - Intrauterine adhesions (IUAs) are mainly derived from fibrous tissue formation following endometrial damage. The aim of the present study was to assess whether fibrosis markers, estrogen receptor (ER)alpha and the stromal derived factor (SDF)-1/C-X-C chemokine receptor type 4 (CXCR-4) axis are abnormally expressed in IUA endometrium. A total of 76 human endometrial biopsy samples (normal, n=20; mild-to-moderate IUAs, n=40; and severe IUAs, n=16) were employed, and Sprague Dawley rat IUA models at different time points were constructed. Subsequently, the expression of transforming growth factor (TGF)-beta1, matrix metalloproteinase (MMP)-9, ERalpha and the SDF-1/CXCR-4 axis was evaluated in human and rat IUAs using histology, immunohistochemistry, reverse transcription quantitative polymerase chain reaction and western blotting. In patients and rats with IUA formation, the expression of TGF-beta1, MMP-9 and ERalpha was significantly higher compared with the control group at the mRNA and protein levels (P<0.05); in addition, in patients, the TGF-beta1, MMP-9 and ERalpha levels were significantly higher in severe IUAs compared with those in mild-to moderate IUA endometrium (P<0.05). Although the chemokine SDF-1 level in rats increased significantly during the early postoperative phase (reaching a peak at the second estrus phase) in rat endometrium (P<0.05), its special receptor CXCR-4 expression did not differ significantly compared with the control group in rats or patients (P>0.05). Our findings indicated that aberrant activation of fibrosis and expression of ERalpha may be involved in the pathology of IUA formation. The role of the SDF-1/CXCR-4 axis in IUAs as inflammatory medium in the short-term or special homing factors for bone marrow mesenchymal stem cells requires further verification in in vivo animal models. PMID- 29568897 TI - miR-29b regulates Ang II-induced EMT of rat renal tubular epithelial cells via targeting PI3K/AKT signaling pathway. AB - Renal interstitial fibrosis is a necessary step in the progression of chronic kidney to end stage renal disease. MicroRNA-29 (miR-29) has been shown to play essential roles in epithelial-mesenchymal transition (EMT), and thus may contribute to the regulation of renal interstitial fibrosis. However, the role of miR-29 in the regulation of EMT during chronic kidney disease and renal transplantation has been a source of intense debate, and the mechanisms underlying this process are incompletely understood. In this study, we investigated the function of miR-29b in the regulation of EMT and to gain a better understanding of the mechanism by which miR-29b modulates EMT by targeting the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway during the process of renal interstitial fibrosis. The rat proximal tubular epithelial cell line NRK-52E was cultured in DMEM and treated with angiotensin II (Ang II) at various concentrations. RT-PCR was performed to investigate changes in the levels of expression of miR-29b in NRK-52E cells and western blotting was used to analyze the expression of PI3K, p-AKT, vimentin and keratin 18. The result of the study show that treatment of NRK-52E cells with Ang II induced the transition of the cellular phenotype from epithelial to mesenchymal and upregulated the PI3K/AKT signaling pathway; this was also found following treatment with a phosphatase and tensin homolog on chromosome 10 (PTEN)-specific inhibitor. Increased expression of miR-29b was able to reverse the phenotype induced by Ang II in NRK-52E cells and blocking miR-29b activity with an miR-29b inhibitor resulted in enhanced EMT. Additionally, the PI3K/AKT signaling pathway was found to be suppressed in the presence of enhanced expression of miR-29b by direct binding to 3'-untranslated region (3'-UTR) of PIK3R2. We concluded that miR-29b plays an important role in the negative regulation of Ang II-induced EMT via PI3K/AKT signaling pathway and propose that enhancing miR-29b level or blocking PI3K/AKT signaling pathway may be a novel therapeutic target in renal interstitial fibrosis. PMID- 29568896 TI - Peroxisome proliferator-activated receptor-gamma and its related pathway in bone marrow mesenchymal stem cell differentiation co-cultured with mechanically stretched ligament fibroblasts. AB - The occurrence of pelvic floor dysfunctional disease (PFD) is closely related with elasticity, toughness, and functional changes of the connective tissue of the pelvic support tissue. Bone marrow mesenchymal stem cells (BMSCs) have been confirmed to have the capacity to differentiate into a variety of cell types such as osteoblasts, chondroblasts, adipocytes and fibroblasts. Therefore, BMSCs have the potential to improve the clinical outcomes for PFD. Peroxisome proliferator activated receptor-gamma (PPAR-gamma), a ligand activated transcription factor, has acquired a great deal of attention as it is involved in the fibrosis and cell differentiation. However, how it is regulated during the process of the differentiation of BMSCs into fibroblasts remains to be defined. The present study investigated the underlying mechanisms of PPAR-gamma effect of mechanical stretch on the differentiation of BMSCs induced by pelvic ligament fibroblasts. PPAR-gamma expression was decreased during the differentiation of BMSCs into fibroblasts by co-cultured stretched fibroblasts. Addition of transforming growth factor-beta1 (TGF-beta1) reduced PPAR-gamma expression and promoted the differentiation of BMSCs. With the employment of endogenous ligand, activation of PPAR-gamma suppressed the BMSC differentiation. Similar effects were also observed with overexpression of PPAR-gamma gene. In addition, decrease of PPAR gamma by the use of shRNA targeting rat PPAR-gamma significantly contributed to BMSC differentiation to fibroblasts. These results indicate that PPAR-gamma negatively regulates the differentiation of BMSCs into fibroblasts. PMID- 29568898 TI - Adiponectin protects against lung ischemia-reperfusion injury in rats with type 2 diabetes mellitus. AB - Adiponectin (APN) has been associated with the pathogenesis of acute brain, liver and heart injury. However, the role of APN in lung ischemia-reperfusion injury (LIRI) in diabetes mellitus remains unclear. To investigate this, the present study evaluated the effects of APN on lung dysfunction and pathological alterations in rats with type 2 diabetes mellitus via lung ischemia/reperfusion (I/R). The lung-protective effects of APN globular domain (gAPN) in rats with type 2 diabetes mellitus were also investigated by measuring the oxygenation index, inflammatory cytokines, lung edema, histopathology, oxidative stress, apoptosis and the protein expression levels of phosphorylated 5'adenosine monophosphate-activated protein kinase (p-AMPK), endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS). The results of the present study demonstrated that the diabetes mellitus rats + I/R (DIR) group exhibited greater concentrations of tumor necrosis factor-alpha and interleukin 6, and increases in the wet-weight to dry-weight ratio, lung injury score, oxidative stress and cellular apoptosis. These effects were accompanied by lower pulmonary oxygenation compared with the normal rat + I/R (NIR) group (P<0.05). Additionally, all of these alterations were attenuated in the NIR + gAPN and DIR + gAPN groups compared with in the NIR and DIR groups, respectively. In the DIR group, the expression levels of p-AMPK/AMPK and eNOS were significantly downregulated, and the levels of iNOS were upregulated, compared with those of the NIR group. Treatment with APN activated AMPK, increased eNOS expression and attenuated iNOS expression. The results of the present study demonstrated that APN exerted protective effects against LIRI via its anti-inflammatory, antioxidative stress and anti-apoptotic activities. These protective effects of APN were eliminated in rats with type 2 diabetes mellitus, in which LIRI was exacerbated. The present study indicated that APN may be a potential therapeutic agent for LIRI in type 2 diabetes mellitus. PMID- 29568899 TI - Role of epithelial chemokines in the pathogenesis of airway inflammation in asthma (Review). AB - As the first barrier to the outside environment, airway epithelial cells serve a central role in the initiation and development of airway inflammation. Chemokines are the most direct and immediate cell factors for the recruitment and migration of inflammatory cells. The present review focused on the role of epithelial chemokines in the pathogenesis of airway inflammation in asthma. In addition to traditional CC family chemokines and CXC family chemokines, airway epithelial cells also express other chemokines, including thymic stromal lymphopoietin and interleukin-33. By expressing and secreting chemokines, airway epithelial cells serve a key role in orchestrating airway inflammation in asthma. PMID- 29568900 TI - Glucosamine promotes chondrocyte proliferation via the Wnt/beta-catenin signaling pathway. AB - The present study investigated the mechanism underlying the effects of glucosamine (GlcN) on the proliferation of chondrocytes isolated from the knee cartilage of Sprague-Dawley rats. Chondrocytes were treated with various concentrations of GlcN or without GlcN. The effects of GlcN on chondrocyte proliferation were determined using reverse transcription-polymerase chain reaction, western blot analysis and immunohistochemistry. The results indicated that GlcN significantly improved chondrocyte viability, accelerated G1/S transition during progression of the cell cycle and promoted the expression of cell cycle regulatory proteins, including cyclin D1, cyclin-dependent kinase (CDK)4 and CDK6, thus indicating that GlcN may promote chondrocyte proliferation. Furthermore, GlcN upregulated the expression levels of Wnt-4, Frizzled-2 and beta catenin, and downregulated the expression of glycogen synthase kinase-3. GlcN also promoted beta-catenin translocation; beta-catenin is able to activate numerous downstream target genes, including cyclin D1. To determine the role of the Wnt/beta-catenin signaling pathway in chondrocyte proliferation, the Wnt/beta catenin signaling pathway was inhibited using Dickkopf-1 (DKK-1), after which chondrocytes were treated with GlcN. The results demonstrated that the expression levels of beta-catenin and cyclin D1 were decreased in chondrocytes treated with DKK-1 and GlcN. These results suggested that GlcN may promote chondrocyte proliferation via the Wnt/beta-catenin signaling pathway. PMID- 29568901 TI - Puerarin promotes MIN6 cell survival by reducing cellular reactive oxygen species. AB - Type 1 diabetes is caused by destruction of the pancreatic beta-cells and, to date, no cure has been developed. Promoting the survival of pancreatic beta-cells may be beneficial for patients with type 1 diabetes. Puerarin is an estrogen analogue that been demonstrated in previous studies to be able to decreased blood glucose in patients with type 1 diabetes. Similar results were demonstrated in previous studies which additionally demonstrated that puerarin was able to decreased blood glucose in type 1 diabetic mice by protecting pancreatic beta cells. However, the mechanism underlying the function of puerarin in pancreatic beta-cells remains unclear. Therefore, the present study sought to investigate the detailed function of puerarin in pancreatic beta-cells. In the present study, H2O2 was used to induce apoptosis. It was observed that puerarin significantly decreased H2O2-induced apoptosis in mouse insulinoma MIN6 cells. It was additionally observed that puerarin decreased the levels of intracellular reactive oxygen species and mitochondrial superoxide in MIN6 cells. The protective effect of puerarin was markedly decreased by 6-aminonicotinamide, an inhibitor of glucose-6-phosphate dehydrogenase (G6PD). In conclusion, the results of the present study suggested that puerarin may increase the activity of G6PD, decreased the level of oxidative stress in MIN6 cells, protect mitochondria and promote MIN6 cell survival. Investigating the mechanism underlying the effect of puerarin in MIN6 cells may provide a novel approach for development of a cure for type 1 diabetes. PMID- 29568902 TI - Dauricine inhibits viability and induces cell cycle arrest and apoptosis via inhibiting the PI3K/Akt signaling pathway in renal cell carcinoma cells. AB - Renal cell carcinoma (RCC), which is derived from the proximal tubules of nephrons, is one of the most common solid cancers. Due to its inherent insensitivity to radiotherapy and chemotherapy, surgery remains the only curative strategy for RCC. Therefore, a novel strategy for treating RCC is urgently needed. This study aims to investigate the effects of dauricine, a bisbenzylisoquinoline alkaloid, in RCC cells and the underlying mechanisms of its action. The effects of dauricine on viability, cell cycle distribution and apoptosis in RCC cells were determined in vitro by MTT assay, flow cytometry and nucleosome ELISA assay, respectively. Mechanism studies were performed by analyzing related proteins using western blotting assays. We show that dauricine effectively inhibits the viability of four RCC cell lines (786-O, Caki-1, A-498 and ACHN). In addition, dauricine induces cell cycle arrest at the G0/G1 phase in RCC cells. Dauricine also induces apoptosis via the intrinsic pathway, since caspase-9 and caspase-3 but not caspase-8 activation was detected after the treatment. Moreover, dauricine was able to inhibit the PI3K/Akt signaling pathway. Our findings suggest inhibitory effects of dauricine in renal cancer cells and provide a better understanding of its underlying mechanism. Our findings suggest that dauricine could be a potential therapeutic agent for treating RCC. PMID- 29568903 TI - PPARalpha activation alleviates damage to the cytoskeleton during acute myocardial ischemia/reperfusion in rats. AB - The cytoskeleton serves an important role in maintaining cellular morphology and function, and it is a substrate of calpain during myocardial ischemia/reperfusion (I/R) injury (MIRI). Calpain may be activated by endoplasmic reticulum (ER) stress during MIRI. The activation of peroxisome proliferator-activated receptor alpha (PPARalpha) may inhibit ischemia/reperfusion damage by regulating stress reactions. The present study aimed to determine whether the activation of PPARalpha protects against MIRI-induced cytoskeletal degradation, and investigated the underlying mechanism involved. Wistar rats were pretreated with or without fenofibrate and subjected to left anterior descending coronary artery ligation for 45 min, followed by 120 min of reperfusion. Calpain activity and the expression of PPARalpha, desmin and ER stress parameters were evaluated. Electrocardiography was performed and cardiac function was evaluated. The ultrastructure was observed under transmission electron microscopy. I/R significantly induced damage to the cytoskeleton in cardiomyocytes and cardiac dysfunction, all of which were improved by PPARalpha activation. In addition, I/R increased ER stress and calpain activity, which were significantly decreased in fenofibrate-pretreated rat heart tissue. The results suggested that PPARalpha activation may exert a protective effect against I/R in the myocardium, at least in part via ER stress inhibition. Suppression of ER stress may be an effective therapeutic target for protecting the I/R myocardium. PMID- 29568904 TI - Roles of elevated 20-HETE in the breakdown of blood brain barrier and the severity of brain edema in experimental traumatic brain injury. AB - Breakdown of the blood brain barrier (BBB) is a secondary injury following traumatic brain injury (TBI) and can lead to the development of brain edema. However, the factors that contribute to the disruption of the BBB and increase the severity of brain edema in TBI remain to be elucidated. 20 hydroxyeicosatetraenoic acid (20-HETE) is a metabolite of arachidonic acid. The inhibition of 20-HETEsynthesis by HET0016 has been suggested as a strategy to decrease brain edema. The present study aimed to investigate whether the elevated production of 20-HETE in cerebral tissue may contribute to BBB breakdown and increase the severity of brain edema in rats with TBI. BBB permeability was quantified using dynamic contrast-enhanced magnetic resonance imaging and brain edema was measured according to brain water content. Superoxide production in injured tissue was also assessed. Liquid chromatography-mass spectrometry was used to evaluate 20-HETE production in injured tissue. Western blot analysis was used to assess the expression of occludin, zonula occludens (ZO)-1, matrix metalloproteinase (MMP)-9, and proteins of the c-Jun N-terminal kinase (JNK) pathway. A total of 3, 24 and 72 h following the induction of TBI, 20-HETE levels, BBB permeability and brain edema were identified to be increased, accompanied by an increase in superoxide production. Conversely, superoxide dismutase levels, in addition to the total antioxidative capability were decreased. In addition, the expression of MMP-9 and proteins of the JNK pathway was upregulated, whereas the expression of occludin and ZO-1 was observed to be suppressed. These results suggested that 20-HETE may aggravate BBB disruption following TBI, via enhancing the expression of MMP-9 and tight junction proteins. Furthermore, oxidative stress and the JNK signaling pathway may be involved in BBB dysregulation. In conclusion, the results of the present demonstrated that the production of 20-HETE was increased in cerebral tissue following traumatic injury, thus suggesting that it may contribute to the compromise of BBB integrity and the development of brain edema. PMID- 29568905 TI - Myricitrin ameliorates ethanol-induced steatosis in mouse AML12 liver cells by activating AMPK, and reducing oxidative stress and expression of inflammatory cytokines. AB - It is necessary to identify compounds that may provide protection against alcoholic liver disease. To the best of our knowledge, the effect of myricitrin on the development of ethanol-induced liver disease has not been previously investigated. The present study aimed to determine the effect of myricitrin on ethanol-induced steatosis in AML12 mouse liver cells and to identify the underlying molecular mechanisms. Ethanol-treated AML12 cells exhibited significant improvement in viability following treatment with myricitrin. Oil red O staining indicated that myricitrin ameliorated ethanol-induced lipid accumulation in cells. Furthermore, following treatment with myricitrin, improvement in ethanol-induced steatosis and decrease in the levels of reactive oxygen species and lipoperoxides were observed in ethanol-stimulated cells. Myricitrin suppressed mRNA and protein expression of tumor necrosis factor-alpha, interleukin-6 and transforming growth factor-beta1 in ethanol-stimulated AML12 cells. Myricitrin markedly increased phosphorylation of adenosine monophosphate activated protein kinase (AMPK) and significantly reduced mRNA expression of sterol-regulatory element-binding protein-1c (SREBP-1c) and fatty acid synthase in ethanol-stimulated AML12 cells. The results of the present study indicate that myricitrin ameliorates ethanol-induced steatosis in AML12 cells by attenuating oxidative stress, suppressing expression of certain inflammatory cytokines and modulating the AMPK/SREBP-1c pathway. PMID- 29568906 TI - miR-124/MCP-1 signaling pathway modulates the protective effect of itraconazole on acute kidney injury in a mouse model of disseminated candidiasis. AB - Previous studies have indicated that monocyte chemoattractant protein-1 (MCP-1), also referred to as C-C motif chemokine ligand 2, has a significant role in the pathogenesis of sepsis, however, how microRNAs (miRs) contribute to this process remains to be fully elucidated. In the present study, using a mouse model of disseminated candidiasis, the renoprotective effect of itraconazole (ITR) and adenovirus-delivered miR-124 was investigated. The mice were treated with ITR (50 mg/kg) or transfected with miR-124 mimics via tail-vein injection 7 days prior to Candida albicans infection. The survival outcome was monitored following candidiasis-induced sepsis with ITR or miR-124 mimics treatment. The levels of pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and IL-6, were determined using enzyme-linked immunosorbent assays. The mRNA and protein levels were assayed using reverse transcription-quantitative polymerase chain reaction and western blot analyses, respectively. The results showed that ITR and miR-124 mimics improved the survival outcome in candidiasis-induced septic mice. The findings also indicated a significant downregulation in the serum levels of TNF-alpha, IL-1beta and IL-6 in the septic mice treated with ITR or miR-124 mimics. Of note, ITR treatment significantly increased the expression of miR-124 and decreased the levels of MCP 1 in the kidneys of the septic mice. It was also shown that the overexpression of miR-124 reduced the expression of MCP-1 and attenuated candidiasis-induced acute kidney injury (AKI) in septic mice. Transfection with miR-124 mimics was equivalent to ITR in reducing the excessive inflammatory response and renal lesions in septic mice. These results provided evidence supporting the use of miR 124 mimics as a therapeutic approach for attenuating candidiasis-induced AKI. PMID- 29568907 TI - Differential modulation by vanadium pentoxide of the secretion of CXCL8 and CXCL11 chemokines in thyroid cells. AB - Recently it has been hypothesized that vanadium serves a carcinogenic role in the thyroid. However, to date, no in vivo or in vitro studies have evaluated thyroid disruption in humans and/or animals following exposure to vanadium. The present study evaluated the effect of vanadium pentoxide (V2O5) on cell viability and proliferation, and chemokine (C-X-C motif) ligand (CXCL)8 and CXCL11 secretion in normal thyrocytes. The results demonstrated that V2O5 had no effect on thyroid follicular cell viability and proliferation. However, V2O5 was able to induce the secretion of CXCL8 and CXCL11 chemokines from thyrocytes. Notably, V2O5 synergistically increased the effect of the interferon (IFN)-gamma on CXCL11 secretion. In addition, V2O5 synergistically increased the effect of tumor necrosis factor-alpha on CXCL8 secretion, and abolished the inhibitory effect of IFN-gamma. Overall this induction of CXCL8 and CXCL11 secretion may lead to the induction and perpetuation of an inflammatory reaction in the thyroid. Further studies are now required to evaluate thyroid function and nodule development in subjects who are occupationally exposed, or living in polluted areas. PMID- 29568908 TI - Quercetin inhibits NTHi-triggered CXCR4 activation through suppressing IKKalpha/NF-kappaB and MAPK signaling pathways in otitis media. AB - Otitis media is one of the most common bacterial infections in children, contributing to hearing loss. A vital bacterial pathogen leading to otitis media development is the nontypeable Haemophilus influenzae (NTHi). Inflammation response is reported as an important characristic for otitis media. Chemokine CXC receptor 4 (CXCR4) is a 352-amino acid seven-span transmembrane G-protein coupled receptor, essential for inflammatory response. However, the possible molecular mechanism indicating the alteration of CXCR4 modulated by NTHi is poorly known. In the present study, NTHi enhanced CXCR4 expression through phosphorylation of IKKalpha and p38, which relied on nuclear factor-kappaB (NF-kappaB) translocation in vitro as well as in the middle ear of mice in vivo. Previously, quercetin, a natural production mainly isolated from rutin, has shown anti-inflammatory effects. Here, we report that quercetin suppressed NTHi-induced CXCR4 expression levels in vitro and in vivo. Quercetin blocked CXCR4 activation through direct IKKbeta phosphorylation inhibition, as well as of p38 MAPK restraining. Hence, identification of quercetin may be a potential therapeutic strategy for treating otitis media induced by NTHi through inflammation suppression. PMID- 29568909 TI - Hyperthermia inhibits the motility of gemcitabine-resistant pancreatic cancer PANC-1 cells through the inhibition of epithelial-mesenchymal transition. AB - Pancreatic cancer (PC) is one of the most common types of malignant tumor and the leading cause of cancer-associated mortality worldwide. The chemotherapeutic drug gemcitabine (GEM) is used as a first-line chemotherapeutic agent for advanced PC. However, the acquisition of drug resistance is a major limitation of the clinical effect of GEM and commonly leads to increased metastasis. The occurrence of epithelial-mesenchymal transition (EMT) has been demonstrated to be the underlying mechanism of acquired resistance. It has been reported that heat treatment is able to inhibit EMT in pancreatic adenocarcinoma cells. In the present study the effect of hyperthermia on the sensitivity of GEM-resistant PC cells was investigated. First a GEM-resistant PC cell line PANC-1 (PAN/GEM) was developed and it was demonstrated that drug resistant PAN/GEM cells exhibited significantly increased migratory and invasive abilities compared with control PANC-1 cells using a Transwell assay. EMT was induced in resistant PAN/GEM cells, followed by reduced epithelial marker epithelial (E)-cadherin expression and increased mesenchymal marker Vimentin expression compared with control PANC-1 cells. Next, the Transwell assay demonstrated that the hyperthermia at 42C for 1 h combined with GEM significantly attenuated migration and invasion in drug resistant PAN/GEM cells, while GEM alone treatment did not significantly affect the migration and invasion. Additionally, EMT in PAN/GEM cells was reversed by hyperthermia, as demonstrated by the restoration of E-cadherin and downregulation of mesenchymal markers Vimentin, matrix metalloproteinase (MMP)2 and MMP9. Furthermore, an MMP2 inhibitor tissue inhibitor of metalloproteinases (TIMP)2 and MMP9 inhibitor TIMP1 were used to treat PAN/GEM cells and it was demonstrated that both inhibitors increased the inhibition of hyperthermia treatment combined with GEM on cell invasion, suggesting an association between cell invasion and MMP2, and MMP9. Additionally, proliferation of PAN/GEM cells following hyperthermia was assessed using an MTT assay. The results demonstrated that proliferation in PAN/GEM cells treated with hyperthermia was significantly inhibited by GEM compared with GEM alone treated cells, indicating that hyperthermia enhanced the inhibition of GEM on cell growth and resensitized the drug-resistant cells to GEM. Overall, the results of the present study suggested that hyperthermia is able to resensitize GEM-resistant PANC-1 cells to GEM by reversing EMT via the regulation of EMT-associated factors, therefore inhibiting cell migration and invasion. PMID- 29568910 TI - Downregulation of miR-374b-5p promotes chemotherapeutic resistance in pancreatic cancer by upregulating multiple anti-apoptotic proteins. AB - Resistance to first-line chemotherapeutic drugs such as gemcitabine contributes to the poor prognosis of patients with pancreatic cancer. MicroRNAs (miRNA) regulate chemoresistance in pancreatic cancer. By analyzing the miRNA sequencing dataset of pancreatic cancer from The Cancer Genome Atlas, it was demonstrated that miR-374b-5p expression was dramatically reduced in pancreatic cancer tissues compared with adjacent normal tissues, as well as decreased in chemoresistant compared with chemosensitive pancreatic carcinoma tissues. The decreased expression of miR-374-5p was associated with poor overall and progression-free survival in patients with pancreatic cancer. Furthermore, increased expression of miR-374b-5p abrogated, while the silencing miR-374b-5p increased the chemoresistance of pancreatic cancer cells to gemcitabine in vitro. Importantly, the upregulation of miR-374b-5p ameliorated the chemoresistance of pancreatic cancer cells to gemcitabine in vivo. It was also demonstrated that miR-374b-5p targeted several anti-apoptotic proteins, including B-cell lymphoma 2, Baculoviral IAP Repeat Containing 3 and X-linked inhibitor of apoptosis in pancreatic cancer cells, which further attenuated chemoresistance in pancreatic cancer. Therefore, the results of the current study indicate that miR-374b-5p serves as a potential diagnostic marker. It also suggests that miR-374b-5p sensitizes cells to chemotherapy and may be used in combination with chemotherapeutic agents such as gemcitabine to treat patients with pancreatic cancer. PMID- 29568912 TI - Clinical study of prenatal ultrasonography combined with T-box transcription factor 1 as a biomarker for the diagnosis of congenital heart disease. AB - Congenital heart disease (CHD) seriously threatens fetal health. Therefore, prenatal examination to detect deformity is extremely important. The present study aimed to investigate the clinical application value of prenatal ultrasonography combined with molecular biology methods in the diagnosis of fetal CHD. A total of 1,000 pregnant women who had received fetal ultrasonography to examine fetal CHD were enrolled. Ultrasounds were performed for fetal heart examination and diagnosis, mainly on fetal heart position, size, structure and function, and heart valve morphology and function. These indexes were tested again 2 weeks after birth. Blood samples were collected from pregnant women with fetal CHD. Polymerase chain reaction (PCR) and western blotting were performed to detect the association between heart development and T-box transcription factor 1 (TBX1) expression. The results revealed that 10 fetuses had CHD (1%), of which ultrasound detected 9 cases. The specificity and sensitivity of ultrasounds were 100 and 90%, respectively. Of the 9 cases were identified by prenatal ultrasound screening, including 2 cases had endocardial cushion defect, 1 case had pulmonary stenosis combined with right ventricular dysplasia, 1 case had tetralogy of Fallot combined with a cleft lip and palate, 2 cases had ventricular septal defect, 1 case had a single ventricle defect, 1 case had Ebstein and 1 case had a triatrial heart. One case of ventricular septal defect was missed prior to delivery. PCR and western blotting demonstrated that TBX1 expression may be associated with CHD. Therefore, ultrasonography combined with laboratory examinations represent efficient, economic and safe methods for fetal CHD detection. These methods may be significant to improve the rate of CHD diagnosis, and require further investigation. PMID- 29568911 TI - miR-25 enhances cell migration and invasion in non-small-cell lung cancer cells via ERK signaling pathway by inhibiting KLF4. AB - In recent years, microRNAs (miRNAs/miRs) have gained increasing interest in cancer research. Increasing evidences demonstrated that miRNAs are important for tumor early detection and prognosis. The present study aimed to explore the function of miR-25 in non-small-cell lung cancer (NSCLC) and its underlying mechanisms. The expression levels of miR-25 and Kruppel-like factor 4 (KLF4) were assessed in 31 pairs of tissue from patients with NSCLC. In addition, the biological roles of miR-25 in NSCLC were analyzed via a cell wound healing assay, Transwell invasion and migration assays. Target genes of miR-25 were predicted using TargetScan and verified via a dual luciferase activity assay, western blotting and reverse transcription-quantitative polymerase chain reaction. The downstream signaling pathway was confirmed by western blot analysis. In the present study, miR-25 was overexpressed in 31 NSCLC samples compared with in corresponding normal tissues. Overexpression of miR-25 using miR-25 mimics markedly promoted NSCLC cell migration and invasion, while inhibition of miR-25 exerted the opposite effect. KLF4 was suggested to be a novel target gene of miR 25 in NSCLC cells. Knockdown of KLF4 promoted the migration and invasion of NSCLC cells, whereas rescue of KLF4 expression reduced cell motion ability in miR-25 overexpressing NSCLC cells. Furthermore, it was demonstrated that miR-25 activated the extracellular signal-regulated kinase (ERK) signaling pathway, which eventually led to increased vimentin, matrix metalloproteinase 11 and N cadherin levels, and the downregulation of E-cadherin expression by inhibiting the expression of KLF4. In conclusion, miR-25 was demonstrated to activate the ERK signaling pathway by directly targeting KLF4, promoting cell migration and invasion. The findings of the present study indicated that miR-25 or KLF4 may serve as a therapeutic target for the treatment of NSCLC. PMID- 29568913 TI - A novel therapeutic strategy of personalized medicine based on anti-epidermal growth factor receptor monoclonal antibodies in patients with metastatic colorectal cancer. AB - Achieving tumor shrinkage may be a clinically relevant improvement in the treatment of metastatic colorectal cancer (mCRC). The present study attempted to evaluate early tumor shrinkage (ETS) and deepness of response over 6-8 courses of therapy, which were assessed previously in first-line trials of anti-epidermal growth factor receptor (EGFR) monoclonal antibodies. A total of 37 patients with mCRC that was considered unresectable or borderline resectable were enrolled in the study. Patients exhibited the wild-type RAS gene, and anti-EGFR monoclonal antibodies were used as the first-line treatment in the Department of Surgical Oncology at Gifu University School of Medicine (Gifu, Japan) between January 2010 and March 2017. Tumor shrinkage and other characteristics were evaluated according to the Response Evaluation Criteria In Solid Tumors (RECIST) classifications (version 1.1). The 3-year overall survival (OS) rate was >60.0% for all cases (n=37). The mean tumor shrinkage rate in the right side of the colon according to the RECIST classifications was -11.1%, whereas that for CRC on the left side showed a statistically significant difference at -54.0% (P=0.042). In addition, the rates of OS for stable disease + progressive disease compared with partial response + complete response, and those of OS for conversion therapy compared with non-conversion therapy were significantly different (both P<0.001). Carcinoembryonic antigen (CEA) was suggested to be a possible predictive factor for convalescence due to the 50% drop in its value after the 6-8 courses of therapy. Overall, the predictive performance of ETS with respect to PFS and OS is at least as good as the standard RECIST response, with the advantage of an earlier assessment, and this may improve convalescence, with CEA as a marker in support of ETS over a clinical treatment course. In RAS wild-type patients, it is important to evaluate the rate of tumor shrinkage from the beginning of the first line treatment until 6-8 courses of anti-EGFR monoclonal antibodies have been administered. PMID- 29568914 TI - Tumor necrosis factor-alpha-induced protein 8-like-2 is involved in the activation of macrophages by Astragalus polysaccharides in vitro. AB - In previous years, studies have shown that Astragalus polysaccharides (APS) can improve cellular immunity and humoral immune function, which has become a focus of investigations. Tumor necrosis factor-alpha-induced protein 8-like 2 (TIPE2) is a negative regulator of immune reactions. However, the effect and underlying mechanisms of TIPE2 on the APS-induced immune response remains to be fully elucidated. The present study aimed to examine the role of TIPE2 and its underlying mechanisms in the APS-induced immune response. The production of nitric oxide (NO) was detected in macrophages in vitro following APS stimulation. In addition, the present study interfered with the expression of TIPE2 in macrophages, and examined the production of cytokines, NO and components of the mitogen-activate protein kinase (MAPK) signaling pathway following APS stimulation. The results showed that APS was able to activate macrophages by inducing the production of interleukin (IL)-1beta, tumor necrosis factor (TNF) alpha, IL-6 and NO. Furthermore, RAW264.7 cells were stimulated with APS when TIPE2 was silenced, and it was found that the production of TNF-alpha, IL-6, IL 1beta and NO were upregulated, and the signaling pathway of MAPK was activated. Taken together, these results demonstrated that TIPE2 had an important negative effect on the APS-induced production of inflammatory cytokines and NO via the MAPK signaling pathway. PMID- 29568915 TI - Aspirin modulates the inflammatory response in a thrombus-stimulated LMVEC model. AB - The purpose of the present study was to examine whether aspirin interferes with the inflammatory response in a thrombus-stimulated lung microvascular endothelial cell (LMVEC) model. The LMVECs were randomly divided into eight groups: Normal group (group N), model group (group M), model + ASP group (group M+A), model+CX3CL1-short hairpin (sh)RNA group (group M+SH), model + CX3CL1 overexpression vector group (group M+CX3), model + ASP + shRNA group (group M+A+SH), model + ASP + CX3CL1-overexpression vector group (group M+A+CX3), and normal + virus control group (group N+V). The endothelial cells were cultured, and a thrombus was added to the cells. Briefly, 12 h following the precipitation of the thrombus, data from ELISA, reverse transcription-quantitative polymerase chain reaction analysis and confocal microscopy revealed that the levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, CX3C chemokine ligand 1 (CX3CL1), CX3C chemokine receptor 1 (CX3CR1) and nuclear factor-kappaB (NF kappaB) in group M were increased, compared with those in group N (P<0.01). These levels, with the exception of TNF-alpha, were significantly lower in group M+SH, compared with those in group M (P<0.01). Furthermore, the levels of IL-6 in groups M+A, M+CX3 and M+A+CX3 were decreased, compared with those in group M (P<0.01); the level of TNF-alpha in group M+A+SH was decreased, compared with that in group M (P<0.01); the level of CX3CR1 waslower in groups M+A and M+A+SH, compared with that in group M (P<0.01), and the level of NF-kappaB in group M+SH was decreased, compared with the level in group M and group M+A (P<0.05). In conclusion, the thrombus-stimulated LMVEC model exhibited induced production of TNF-alpha, IL-6, CX3CL, CX3CR1, NF-kappaB and intercellular adhesion molecule-1. Furthermore, it was confirmed that the signaling pathways involving CX3CL1-NF kappaB, IL-6 and TNF-alpha were partly inhibited by aspirin. PMID- 29568916 TI - miR-34 modulates apoptotic gene expression in Ingenol mebutate treated keloid fibroblasts. AB - Keloids are benign skin tumors that develop in individuals who have a positive family history of keloid disorders. Keloids are characterized by a deregulated wound-healing process, atypical fibroblasts with extreme deposition of extracellular matrix components, particularly collagen, increased cell proliferation and associated failure of apoptosis. Recently ingenol-mebutate has been used as a novel agent with anti-proliferative activity on human keloids as an alternative treatment option in patients, once conventional therapies have failed. We hypothesized that microRNAs (miR/miRNA) may be involved in the balance between lesion formation and repair. A comprehensive understanding of the molecular mechanism underlying the Ingenol-mebutate response in keloid fibroblast following Ingenol-mebutate exposure has been established previously. Therefore, the present study analyzed changes in miRNAs and apoptotic gene regulation in Ingenol-mebutate treated keloid fibroblast, by reverse transcription-quantitative polymerase chain reaction and a DNA fragmentation assay. The range of upregulated miRNAs and downregulated genes encoding cell death appeared to be associated with the degree of the morphological alterations in Ingenol-mebutate treated keloids. In particular, the upregulation of miR-34a was detected in keloid fibroblasts during and following Ingenol-mebutate exposure. Keloid fibroblasts that overexpressed miR-34a showed differential expression of genes involved in the apoptotic signaling pathway such as p53. In conclusion, the Ingenol-mebutate treatment used here was effective in reducing keloid fibroblast growth in cell culture experiments and the expression of particular miRNAs modulated the pro apoptotic gene expression following Ingenol-mebutate treatment. PMID- 29568917 TI - EPB41L3 is a potential tumor suppressor gene and prognostic indicator in esophageal squamous cell carcinoma. AB - Although there have been reports about the role of erythrocyte membrane protein band 4.1 like 3 (EPB41L3) in several types of cancer, primarily in non-small-cell lung carcinoma, the molecular function and modulatory mechanisms of EPB41L3 remain unclear. In specific, the functional and clinical significance of EPB41L3 in esophageal squamous cell carcinoma (ESCC) has not been explored to date. In the present study, reduced EPB41L3 expression was demonstrated in ESCC cell lines and tissues, which was due to its high methylation rate. Ectopic expression of EPB41L3 in ESCC cells inhibited cell proliferation in vivo and in vitro. In addition, EPB41L3 overexpression induced apoptosis and G2/M cell cycle arrest by activating Caspase-3/8/9 and Cyclin-dependent kinase 1/Cyclin B1 signaling, respectively. Notably, patients with higher EPB41L3 expression had markedly higher overall survival rates compared with patients with lower EPB41L3 expression. In summary, the present results suggest that EPB41L3 may be a tumor suppressor gene in ESCC development, representing a potential therapeutic target and a prognostic indicator for ESCC. PMID- 29568918 TI - Protection of Luteolin-7-O-glucoside against apoptosis induced by hypoxia/reoxygenation through the MAPK pathways in H9c2 cells. AB - Myocardial hypertrophy is often associated with myocardial infarction. Luteolin-7 O-glucoside (LUTG) has the prosperity of preventing cardiomyocyte injury. The current study aimed to explore the potential protective effect of LUTG and its relevant mechanisms in the heart. To establish the cardiac hypertrophy model in vitro, Angiotensin II (Ang II) was used to stimuli H9c2 cells in this study. The CCK-8 assay showed that LUTG pretreatment improved cell viability of cardiomyocytes co-treated with Ang II and ischemia/reperfusion. LUTG decreased the reactive oxygen species levels. Furthermore, it was demonstrated LUTG could reduce the release amount of lactate dehydrogenase and recover the catalase activity according to the flow cytometry analysis, and activity detection, respectively in Ang II-H/R-treated H9c2 cells. In addition, the flow cytometry analysis showed that the pretreatment of LUTG mitigated cell apoptosis induced by hypoxia/reoxygenation in the cardiac hypertrophy model. Meanwhile, reverse transcription-quantitative polymerase chain reaction and western blot assays showed that the apoptosis-related genes, including poly (ADP-ribose) polymerase, Fas, Fasl and Caspase-3 were downregulated at the transcriptional and translational levels. Notably, the protien expression of phosphorylated (p) extracellular signal-regulated kinas (ERK) 1/2, p-janus kinase and p-P38 were reduced, while the expression of p-ERK5 was elevated in the LUTG pretreatment groups compared with the hypoxia/reoxygenation treatment group. Based on these results, it was suggested that the anti-apoptosis effect of LUTG may be associated with regulating the activation of mitogen-activated protein kinases signaling pathways. PMID- 29568919 TI - Downregulation of human choline kinase alpha gene expression by miR-876-5p. AB - Choline kinase (CK) is the first enzyme in the CDP-choline pathway for the synthesis of phosphatidylcholine, the most abundant phospholipid in the mammalian cell membrane. This enzyme exists as three isozymes (alpha1, alpha2 and beta) and the CKalpha isozyme has been implicated in cancer pathogenesis. Inhibition of CK activity has been proposed for cancer therapies. MicroRNAs (miRNAs/miRs) are non coding RNAs that serve important roles in diverse biological pathways and human diseases, including cancer. However, the regulation of CKalpha gene expression by miRNAs has never been investigated, to the best of the authors' knowledge. In the present study, two miRNA mimics, miR-876-5p and miR-646, were transfected into the HepG2 cell line and the effect of these miRNAs on the levels of CKalpha mRNA were determined by reverse transcription-quantitative polymerase chain reaction. Cells transfected with 25 nM miR-876-5p for 48 h exhibited significantly lower levels of CKalpha mRNA. Following optimization, miR-876-5p caused four times lower levels of CKalpha mRNA compared to the negative control. Effects of the miRNAs on HepG2 cell viability and cellular morphology were additionally analyzed using an MTT cell viability assay and scanning electron microscopy, respectively. HepG2 cells that were transfected with the optimum concentration of miR-876-5p for the optimum duration exhibited 25% lower viability than negative control and signs of apoptosis in electron micrographs. The results suggested miR-876-5p as a potential miRNA modulator of CKalpha expression in the cells, and may be relevant for the design of more effective anticancer strategy targeting CK. PMID- 29568920 TI - Oridonin induces apoptosis in oral squamous cell carcinoma probably through the generation of reactive oxygen species and the p38/JNK MAPK pathway. AB - The anti-inflammatory effects of oridonin (Ordn) have been well established in previous studies. However, the apoptotic effects of Ordn on oral cancer cells have not yet been evaluated, at least to the best of our knowledge. The aim of this study was to examine the apoptotic activity of Ordn in oral squamous cell carcinoma cells and to eluciudate the underlying mechanisms. For this purpose, we employed experimental techniques, such as MTT assay, DAPI staining, soft agar assay, flow cytometry and western blot analysis. Our results revealed that Ordn suppressed oral cancer cell proliferation and soft agar colony formation, while it induced reactive oxygen species (ROS)-dependent apoptosis in a dose or time dependent manner. The generation of ROS was detected in HN22 and HSC4 cells treated with Ordn and the use of the free radical scavenger, N-acetyl-L-cysteine, almost blocked Ordn-induced apoptosis. The phosphorylation of JNK and p38 mitogen activated protein kinase (MAPK) was manifested in the Ordn-treated cells. Furthermore, Ordn induced the apoptosis of oral cancer cells through the mitochondrial-dependent pathway, involving the loss of mitochondrial membrane potential, the release of cytochrome c, the induction of poly(ADP-Ribose) polymerase (PARP) cleavage, alterations in the ratios of apoptotic proteins and the activation of the caspase cascade. Taken together, these findings indicate that Ordn induces the apoptosis of oral cancer cells probably via ROS-mediated JNK/p38 MAPK and mitochondrial pathways; thus, Ordn may have potential for use in the treatment of oral cancer. PMID- 29568921 TI - Fisetin-treatment alleviates airway inflammation through inhbition of MyD88/NF kappaB signaling pathway. AB - Asthma is a common chronic airway inflammation disease and is considered as a major public health problem. Fisetin (3,3',4',7-tetrahydroxyflavone) is a naturally occurring flavonoid abundantly found in different vegetables and fruits. Fisetin has been reported to exhibit various positive biological effects, including anti-proliferative, anticancer, anti-oxidative and neuroprotective effects. We evaluated the effects of fisetin on allergic asthma regulation in mice. Mice were first sensitized, then airway-challenged with ovalbumin (OVA). Whether fisetin treatment attenuated OVA-induced airway inflammation was examined via inflammation inhibition through MyD88-related NF-kappaB (p65) signaling pathway. Mice were divided into the control (Con), OVA-induced asthma (Mod), 40 (FL) and 50 (FH) mg/kg fisetin-treated OVA-induced asthma groups. Our results found that OVA-induced airway inflammation in mice caused a significant inflammatory response via the activation of MyD88 and NF-kappaB signaling pathways, leading to release of pro-inflammatory cytokines. In contrast, fisetin treated mice after OVA induction inhibited activation of MyD88 and NF-kappaB signaling pathways, resulting in downregulation of pro-inflammatory cytokine secretion. Further, fisetin significantly ameliorated the airway hyperresponsiveness (AHR) towards methacholine (Mch). In addition, fisetin reduced the number of eosinophil, monocyte, neutrophil and total white blood cell in the bronchoalveolar lavage fluid (BALF) of OVA-induced mice. The serum and BALF samples obtained from the OVA-induced mice with fisetin showed lower levels of pro-inflammatory cytokines. The results of our study illustrated that fisetin may be a new promising candidate to inhibit airway inflammation response induced by OVA. PMID- 29568922 TI - Phylogeny and polymorphism in the long control regions E6, E7, and L1 of HPV Type 56 in women from southwest China. AB - Globally, human papillomavirus (HPV)-56 accounts for a small proportion of all high-risk HPV types; however, HPV-56 is detected at a higher rate in Asia, particularly in southwest China. The present study analyzed polymorphisms, intratypic variants, and genetic variability in the long control regions (LCR), E6, E7, and L1 of HPV-56 (n=75). The LCRs, E6, E7 and L1 were sequenced using a polymerase chain reaction and the sequences were submitted to GenBank. Maximum likelihood trees were constructed using Kimura's two-parameter model, followed by secondary structure analysis and protein damaging prediction. Additionally, in order to assess the effect of variations in the LCR on putative binding sites for cellular proteins, MATCH server was used. Finally, the selection pressures of the E6-E7 and L1 genes were estimated. A total of 18 point substitutions, a 42-bp deletion and a 19-bp deletion of LCR were identified. Some of those mutations are embedded in the putative binding sites for transcription factors. 18 single nucleotide changes occurred in the E6-E7 sequence, 11/18 were non-synonymous substitutions and 7/18 were synonymous mutations. A total 24 single nucleotide changes were identified in the L1 sequence, 6/24 being non-synonymous mutations and 18/24 synonymous mutations. Selective pressure analysis predicted that the majority of mutations of HPV-56 E6, E7 and L1 were of positive selection. The phylogenetic tree demonstrated that the isolates distributed in two lineages. Data on the prevalence and genetic variation of HPV-56 types in southwest China may aid future studies on viral molecular mechanisms and contribute to future investigations of diagnostic probes and therapeutic vaccines. PMID- 29568923 TI - ATM-JAK-PD-L1 signaling pathway inhibition decreases EMT and metastasis of androgen-independent prostate cancer. AB - Castration-resistant prostate cancer (CRPC), also known as androgen-independent prostate cancer, frequently develops local and distant metastases, the underlying mechanisms of which remain undetermined. In the present study, surgical specimens obtained from patients with clinical prostate cancer were investigated, and it was revealed that the expression levels of ataxia telangiectasia mutated kinase (ATM) were significantly enhanced in prostate cancer tissues isolated from patients with CRPC compared with from patients with hormone-dependent prostate cancer. CRPC C4-2 and CWR22Rv1 cells lines were subsequently selected to establish prostate cancer models, and ATM knockout cells were established via lentivirus infection. The results of the present study demonstrated that the migration and epithelial-mesenchymal transition (EMT) of ATM knockout cells were significantly decreased, which suggested that ATM is closely associated with CRPC cell migration and EMT. To further investigate the mechanisms underlying this process, programmed cell death 1 ligand 1 (PD-L1) expression was investigated in ATM knockout cells. In addition, inhibitors of Janus kinase (JAK) and signal transducer and activator of transcription 3 (STAT3; Stattic) were added to C4-2 Sc and CWR22Rv1-Sc cells, and the results demonstrated that PD-L1 expression was significantly decreased following the addition of JAK inhibitor 1; however, no significant change was observed following the addition of Stattic. Furthermore, a PD-L1 antibody and JAK inhibitor 1 were added to C4-2-Sc and CWR22Rv1-Sc cells, and it was revealed that cell migration ability was significantly decreased and the expression of EMT-associated markers was effectively reversed. The results of the present study suggested that via inhibition of the ATM-JAK-PD-L1 signaling pathway, EMT, metastasis and progression of CRPC may be effectively suppressed, which may represent a novel therapeutic approach for targeted therapy for patients with CRPC. PMID- 29568924 TI - Downregulation of lncRNA H19 inhibits migration and invasion of human osteosarcoma through the NF-kappaB pathway. AB - The present study aimed to investigate the role of long non-coding RNA (lncRNA) H19 in the development of osteosarcoma and to determine the underlying mechanism involved. A total of 40 patients with osteosarcoma were selected and the expression level of H19 in tumor tissue and adjacent healthy tissue was detected by reverse transcription-quantitative polymerase chain reaction. Survival curves were plotted using the Kaplan-Meier method to investigate the prognostic value of H19 expression level for patients with osteosarcoma. H19 knockdown osteosarcoma cell lines were constructed using small interfering (si)RNA transfection. Cell migration and invasion abilities were measured by Transwell migration and invasion assays, respectively. Western blot analysis was performed to detect the expression levels of phosphatidylinositol 3-kinase (PI3K), phospho (p)-PI3K, RAC alpha serine/threonine-protein kinase (AKT), p-AKT and NF-kappaB inhibitor alpha (IkappaBalpha) in osteosarcoma cells transfected with H19 siRNA. Expression level of H19 was significantly elevated in tumor tissue compared with adjacent healthy tissue. Expression level of H19 was positively associated with distant metastasis of osteosarcoma (P<0.01), but not with gender and age. Overall survival of patients with osteosarcoma with high H19 level was significantly shorter compared with patients with low H19 expression (P<0.05). H19 knockdown significantly reduced migration and invasion ability of osteosarcoma cells. Significantly decreased levels of p-PI3K and p-AKT, and elevated level of IkappaBalpha were observed in H19 knockdown osteosarcoma cells compared with control osteosarcoma cells, while no significant differences in levels of PI3K and AKT were observed. Therefore, the present study demonstrated that knockdown of lncRNA H19 can inhibit migration and invasion of human osteosarcoma cells by inhibiting the nuclear factor-kappaB pathway. PMID- 29568925 TI - [Corrigendum] Altered expression of microRNA-98 in IL-1beta-induced cartilage degradation and its role in chondrocyte apoptosis. AB - Following the publication of this article, we realized that the joint first author's name had been printed incorrectly in the journal: This was mispelled as "Lingqing Chen". The corrected name (Lingqiang Chen) is featured here. We regret any inconvenience this has caused, and thank the Editor for allowing us the opportunity to publish a Corrigendum. [the original article was published in the Molecular Medicine Reports 16: 3208-3216, 2017; DOI: 10.3892/mmr.2017.7028]. PMID- 29568926 TI - DNA methylation is related to the occurrence of breast cancer and is not affected by culture conditions. AB - The present study aimed to explore the relationship between DNA methylation and breast cancer under different cell culture conditions. MCF-7 breast cancer cells were cultured in two-dimensional (2D), three-dimensional (3D) and orthotopic transplantation (Ti) adhesion substrates. Principal component analysis (PCA) was used for global visualization of these three samples. The methylation status of CpG sites was examined by unsupervised clustering analysis. Scatter plots and histograms were constructed from the mean beta-values from 3D vs. 2D, 3D vs. Ti and Ti vs. 2D analysis. In addition, analyses of Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were conducted to explore the putative biological functions in which mutL homolog (MLH), phosphatase and tensin homolog (PTEN), runt-related transcription factor (RUNX), Ras association domain family (RASSF), cadherin 1 (CDH1), O-6-methylguanine-DNA methyltransferase (MGMT) and P16 may serve a role. Quantitative methylation-specific polymerase chain reaction (QMSP) was performed to determine the influence of culturing conditions on important gene expression. Results from PCA analysis indicated that the three samples were closely connected with each other. Venn diagrams revealed that certain differential methylation positions were common among the three sample groups, and 116 CpG positions were identified that appeared to be hypermethylated. The methylation patterns were more similar between 3D vs. 2D cultures compared with those between 3D vs. Ti or between Ti vs. 2D. Results of GO term and KEGG pathway analyses indicated that genes were enriched in four pathways, including transporter activity and G-protein coupled receptor activity. In addition, QMSP analysis identified no notable differences in the methylation status of MLH, PTEN, RUNX, RASSF, CDH1, MGMT and P16 under 2D, 3D and Ti culture conditions. In conclusion, abnormal DNA methylation is related with breast cancer, and the methylation status did not change in breast cancer cells cultured in different conditions. PMID- 29568927 TI - miR-185 and miR-29a are similarly expressed in the bronchoalveolar lavage cells in IPF and lung cancer but common targets DNMT1 and COL1A1 show disease specific patterns. AB - Idiopathic pulmonary fibrosis (IPF) and lung cancer (LC) constitute two progressively devastating lung diseases with common risk factors including aging and smoking. There is an increasing interest in the investigation of common pathogenic mechanisms between IPF and LC with therapeutic implications. Several oncomirs, microRNAs associated with malignancy, are also linked with IPF. miR-29a and miR-185 downregulation is probably involved both in carcinogenesis and fibrogenesis. We have previously observed miR-29a and miR-185 downregulation in IPF cells from bronchoalveolar lavage (BAL) and in this study we investigated their expression in LC BAL cells. Common targets of miR-29a and miR-185 such as DNA methyltransferase (DNMT)1, DNMT3b, COL1A1, AKT1 and AKT2 were measured. Potential correlations with pulmonary function tests, smoking status and endobronchial findings were investigated. Similar levels of miR-29a and miR-185 were detected in IPF and LC while their common targets AKT1 and DNMT3b were not found to differ, suggesting potential pathogenetic similarities at the level of key epigenetic regulators. By conrast, COL1A1 mRNA levels were increased in IPF suggesting a disease-specific mRNA signature. Notably, DNMT1 was downregulated in the LC group and its expression was further reduced in the presence of increasing malignant burden as it was implied by the endobronchial findings. PMID- 29568928 TI - Oral supplementation with ursolic acid ameliorates sepsis-induced acute kidney injury in a mouse model by inhibiting oxidative stress and inflammatory responses. AB - Ursolic acid (UA) as a multiple bioactive native compound has recently been demonstrated to treat sepsis in animal models. However, the beneficial effects of UA in sepsis-induced acute kidney injury (AKI) are not completely understood. In the present study, the effect of UA on sepsis-induced AKI in cecal ligation and puncture (CLP) surgery mice was investigated. Renal histomorphological analysis was performed by hematoxylin and eosin staining. The expression of inflammatory markers in the kidney of septic mice was measured by reverse transcription quantitative polymerase chain reaction and western blotting. The results demonstrated that UA administration improved survival in septic mice induced by CLP surgery. The treatment with UA revealed protection against AKI induced by CLP surgery, including the alleviation of glomerular damage and vacuolization in the proximal tubules. In addition, the effects of UA on oxidative stress and inflammation in septic mice were determined. The findings suggested that UA may protect against sepsis-induced AKI by inhibiting reactive oxygen species and inflammatory cytokines, including tumor necrosis factor-alpha, interleukin (IL) 1beta and IL-6, in the kidney from septic mice. Finally, UA inhibited CLP-induced activation of nuclear factor-kappaB signaling in the kidney from septic mice. The findings of the present study demonstrated that UA may be used as a potential therapeutic agent for complications of sepsis, especially for sepsis-induced AKI. PMID- 29568929 TI - Effect of KNDC1 overexpression on the senescence of human umbilical vein endothelial cells. AB - Kinase non-catalytic C-lobe domain containing 1 (KNDC1) exists in dendrites, guanine nucleotide exchange factor complexes and neuronal cell bodies as a putative protein-protein interaction module that regulates a number of signaling pathways. Previous studies have demonstrated that the knockdown of KNDC1 delays human umbilical vein endothelial cell (HUVEC) senescence. However, the effect of KNDC1 overexpression on HUVEC function remains unclear. In the present study, an adenovirus vector carrying KNDC1 was constructed and then transfected into endothelial cells to observe cell senescence. Furthermore, the effect of KNDC1 overexpression on HUVEC senescence was investigated in vitro and the underlying molecular mechanism was investigated. Senescence-associated beta-galactosidase staining was used to determine cellular senescence and reactive oxygen species (ROS) were monitored to detect the level of cell oxidative stress. The mRNA transcription level and protein expression were analyzed by reverse transcription quantitative polymerase chain reaction and western blot analysis, respectively. The results demonstrated that KNDC1 overexpression possibly inhibited HUVEC activity and function and promoted HUVEC senescence. Mechanistic studies demonstrated that KNDC1 triggered a p53-ROS positive feedback loop, which serves a crucial role in regulating senescence. In conclusion, to the best of the authors' knowledge, this is the first time that KNDC1-adenovirus vector inhibition of HUVEC proliferation by activating the p53 signaling pathway has been reported. Theoretically, the results of the present study also support KNDC1 as a therapeutic target for future anti-senescence. PMID- 29568930 TI - Angiopoietin-2 promotes extracellular matrix degradation in human degenerative nucleus pulposus cells. AB - In contrast to healthy intervertebral discs (IVDs), degenerate IVDs become vascularized. Here, we determined the role of an angiogenesis promoter, angiopoietin (Ang)-2, in the pathology of IVD degeneration (IDD). We evaluated degree of IDD using the Pfirrmann grading system. We used quantitative real-time polymerase chain reaction and western blotting to analyze ANG2 gene expression and Ang-2 protein levels, respectively. The involvement of Ang-2 in IVD degradation and regulation of nuclear factor-kappaB (NF-kappaB) signaling was examined by immunohistochemistry, western blotting and immunofluorescence. As a result, 10 samples with grades II and III IDD were categorized as the mild IDD group; for comparison, another 10 specimens with grades IV and V constituted the severe IDD group. Ang-2 expression was significantly higher in severe IDD than in mild IDD. Exogenous Ang-2 administration led to increased production of catabolic proteinases and loss of aggrecan and collagen II in degenerative NP cell cultures, which was mediated by the NF-kappaB signaling pathway. Elevated Ang-2 levels also increased interleukin-1beta expression in degenerative NP cells. We conclude that the release of Ang-2 aggravates NP cell degradation and plays an important role in IDD. Ang-2 may thus constitute a novel therapeutic target for the treatment of IVD. PMID- 29568931 TI - miR-590-3p mediates melatonin-induced cell apoptosis by targeting septin 7 in the human osteoblast cell line hFOB 1.19. AB - The present study aimed to investigate the association between septin 7 (SEPT7) and melatonin-induced apoptosis in the human fetal osteoblastic cell line hFOB 1.19. MicroRNA (miR)-590-3p was identified by identifying overlapping miRNAs that target SEPT7, across different databases (miRDB, DIANA and Targetscan). Apoptosis was assessed via flow cytometric analysis. Small interfering RNA of SEPT7 and a miR-590-3p inhibitor were used for gene silencing and the efficiency was assessed by reverse transcription-quantitative polymerase chain reaction. Western blotting was used to measure the expression of proteins associated with pathways mediating endoplasmic reticulum stress and melatonin-induced apoptosis. The present study identified that SEPT7 was a potential target of miR-590-3p and demonstrated that SEPT7 is associated with mediating the pro-apoptotic effect of miR-590-3p in human osteoblast cell line hFOB 1.19. High concentrations of melatonin may result in the inhibition of miR-590-3p expression, leading to the upregulation of target genes that promote apoptosis. PMID- 29568932 TI - Lemongrass essential oil and citral inhibit Src/Stat3 activity and suppress the proliferation/survival of small-cell lung cancer cells, alone or in combination with chemotherapeutic agents. AB - Small-cell lung cancer (SCLC) is intractable due to its high propensity for relapse. Novel agents are thus needed for SCLC treatment. Lemongrass essential oil (LG-EO) and its major constituent, citral, have been reported to inhibit the proliferation and survival of several types of cancer cells. However, the precise mechanisms through which LG-EO and citral exert their effects on SCLC cells have not been fully elucidated. SCLC cells express Src and have high levels of Src tyrosine kinase (Src-TK) activity. In most SCLC cell lines, constitutive phosphorylation of Stat3(Y705), which is essential for its activation, has been detected. Src-TK can phosphorylate Stat3(Y705), and activated Stat3 promotes the expression of the anti-apoptotic factors Bcl-xL and Mcl-1. In the present study, LG-EO and citral prevented Src-TK from phosphorylating Stat3(Y705), resulting in decreased Bcl-xL and Mcl-1 expression, in turn suppressing the proliferation/survival of SCLC cells. To confirm these findings, the wild-type src gene was transfected into the LU135 SCLC cell line (LU135-wt-src), in which Src and activated phospho-Stat3(Y705) were overexpressed. The suppression of cell proliferation and the induction of apoptosis by treatment with LG-EO or citral were significantly attenuated in the LU135-wt-src cells compared with the control LU135-mock cells. The signal transducer and activator of transcription 3 (Stat3) signaling pathway is also associated with intrinsic drug resistance. LU135-wt-src cells were significantly resistant to conventional chemotherapeutic agents compared with LU135-mock cells. The combined effects of citral and each conventional chemotherapeutic agent on SCLC cells were also evaluated. The combination treatment exerted additive or more prominent effects on LU135-wt-src, LU165 and MN1112 cells, which are relatively chemoresistant SCLC cells. These findings suggest that either LG-EO or citral, alone or in combination with chemotherapeutic agents, may be a novel therapeutic option for SCLC patients. PMID- 29568933 TI - Effects and mechanism of amyloid beta1-42 on mitochondria in astrocytes. AB - Amyloid beta (Abeta)1-42 is strongly associated with Alzheimer's disease (AD). The effects of Abeta1-42 on astrocytes remain largely unknown. The present study focused on the effects of Abeta1-42 on U87 human glioblastoma cells as astrocytes for in vitro investigation and mouse brains for in vivo investigation. The mechanism and regulation of mitochondria and cytochrome P450 reductase (CPR) were also investigated. As determined by MTT assays, low doses of Abeta1-42 (<1 uM) marginally promoted astrocytosis compared with the 0 uM group within 24 h, however, after 48 h treatment these doses reduced cellular growth compared with the 0 uM group. Furthermore, Abeta1-42 doses >5 uM inhibited the growth of U87 cells compared with the 0 uM group after 24 and 48 h treatment. Immunofluorescence analysis demonstrated that astrocytosis was also observed in early stage AD mice compared with wild-type (WT) mice. In addition, concentrations of Abeta1-42 were also significantly higher in early stage AD mice compared with WT mice, however, the levels were markedly lower compared with later stage AD mice, as determined by ELISA. In addition to increased levels of Abeta1-42 in mice with later stage AD, reduced astrocyte staining was observed compared with WT mice. Western blotting indicated that the effect of Abeta1-42 on U87 cell apoptosis may be regulated via Bcl-2 and caspase-3 located in mitochondria, whose functions, including adenosine triphosphate generation, electron transport chain and mitochondrial membrane potential, were inhibited by Abeta1-42. During this process, the expression and activity of cytochrome P450 reductase was also downregulated. The current study provides novel insight into the effects of Abeta1-42 on astrocytes and highlights a potential role for astrocytes in the protection against AD. PMID- 29568934 TI - Tanshinone-IIA attenuates the deleterious effects of oxidative stress in osteoporosis through the NF-kappaB signaling pathway. AB - Osteoclasts are responsible for bone resorption caused by bone microstructural damage and bone-related disorders. Evidence shows that tanshinone IIA (Tan-IIA), a traditional Chinese medicine, is used clinically as a drug for the treatment of cardiovascular and cerebrovascular diseases. However, the efficacy and mechanism underlying the effect of Tan-IIA on the viability of osteoclasts remain to be fully elucidated. The present study investigated the therapeutic effects of Tan IIA on osteoblast differentiation and oxidative stress in vitro and in vivo. Cell viability was analyzed and oxidative stress was examined in the osteoblasts. Wnt1sw/sw mice were used to investigate the therapeutic effects of Tan-IIA on spontaneous tibia fractures and severe osteopenia. The bone strength, collagen and mineral were examined in the tibia. Osteoblast activity was also analyzed in the experimental mice. The Tan-IIA-induced differentiation of osteoclasts and the mechanism of action were investigated in osteocytes. The data showed that Tan-IIA treatment improved cell viability. The data also demonstrated that Tan-IIA decreased the levels of H2O2, accumulation of reactive oxygen species and apoptosis of osteoblasts. Tan-IIA inhibited the deleterious outcomes triggered by oxidative stress. In addition, Tan-IIA inhibited the activation of nuclear factor (NF)-kappaB and its target genes, tumor necrosis factor (TNF)-alpha, inducible nitric oxide synthase and cyclooxygenase 2, and increased the levels of TNF receptor-associated factor 1 and inhibitor of apoptosis protein-1/2 in the osteocytes. Furthermore, it was shown that Tan-IIA reduced the propensity to fractures and severe osteopenia in mice with osteoporosis. Tan-IIA also exhibited improved bone strength, mineral and collagen in the bone matrix of the experimental mice. It was found that the Tan-IIA-mediated benefits on osteoblast activity and function were through the NF-kappaB signaling pathway. Taken together, the data obtained in the present study suggested that Tan-IIA had protective effects against oxidative stress in osteoblastic differentiation in mice with osteoporosis by regulating the NF-kappaB signaling pathway. PMID- 29568935 TI - Integrated analysis of B-cell and T-cell receptors by high-throughput sequencing reveals conserved repertoires in IgA nephropathy. AB - Immunoglobulin A nephropathy (IgAN) is a type of glomerular disorder associated with immune dysregulation, and understanding B-/T-cell receptors (BCRs/TCRs) may be valuable for the development of specific immunotherapeutic interventions. In the present study, B and T cells were isolated from IgAN patients and healthy controls, and the composition of the BCR/TCR complementarity-determining region (CDR)3 was analyzed by multiplex polymerase chain reaction, high-throughput sequencing and bioinformatics. The present results revealed that the BCR/TCR CDR3 clones were expressed at very low frequencies, and the composition of clone types in patients with IgAN was skewed; the majority of clones were unique, and only 12 BCR and 228 TCR CDR3 clones were public ones, of which 16 were expressed at a significantly higher frequency in patients with IgAN (P<0.001). There were also certain conserved amino acid residues between unique clones or groups, and the residues GMDV, EQY and EQF were recurring only in the IgAN group. In addition, some VDJ gene recombinations indicated great variation between groups, including 4 high-frequency VDJ gene recombinations in the IgAN patients (P<0.001). Immune repertoires provide novel information, and conserved BCR/TCR CDR3 clones and VDJ gene recombinations with great variation may be potential therapeutic targets for IgAN patients. PMID- 29568936 TI - Islet-1 promotes the proliferation and invasion, and inhibits the apoptosis of A375 human melanoma cells. AB - The aim of this study was to examine the effects of the insulin gene enhancer binding protein, islet-1 (ISL1), on the proliferation, invasion and apoptosis of the human melanoma cell line, A375. An ISL1 overexpression lentiviral vector was constructed and transfected into the A375 cells. The proliferation of the A375 cells transfected with the ISL1 vector (termed A375/ISL1 cells) was examined by MTT assay, flow cytometry and TUNEL assay, and cell invasion was examined by Transwell assay. The expression levels of matrix metalloproteinase (MMP)-2 and MMP-9 were measured by qPCR and western blot analysis; the expression levels of Akt and p-Akt were measured in the cells treated with vascular endothelial growth factor (VEGF) and the PI3K/Akt inhibitor, LY294002, by western blot analysis. The optical density value of the A375/ISL1 cells was increased after 12 h of culture (P<0.001), as shown by MTT assay. The ratio of apoptotic A375/ISL1 cells was significantly decreased (P<0.001), as shown by flow cytometry and TUNEL assay. In addition, the average penetration rate of the A375/ISL1 cells significantly increased (P<0.001), as shown by Transwell assay. The expression levels of MMP-2 and MMP-9 were significantly increased in the A375/ISL1 cells, as shown by qPCR and western blot analysis (P<0.001). Moreover, treatment of the A375/ISL1 cells with VEGF for 48 h increased the expression of Akt and p-Akt compared with the control cells transfected with A375/green fluorescent protein (GFP) (P<0.05; P<0.001, respectively). In addition, in the A375/ISL1 cells treated with the LY294002 inhibitor for 24 and 48 h, the level of Akt was also found to increase compared to the control A375/GFP cells (P<0.05). On the whole, the findings of this study indicate that the overexpression of ISL1 promotes the proliferation and invasion, and inhibits the apoptosis of A375 melanoma cells. ISL1 thus plays an important role in A375 cell survival, and these effects are possibly mediate via the PI3K/Akt signaling pathway. PMID- 29568937 TI - Genetic analysis of sick sinus syndrome in a family harboring compound CACNA1C and TTN mutations. AB - Sick sinus syndrome (SSS) is a sinus node dysfunction characterized by severe sinus bradycardia. SSS results in insufficient blood supply to the brain, heart, kidneys, and other organs and is associated with the increased risk of sudden cardiac death. Bradyarrhythmia appears in the absence of any associated cardiac pathology and displays a genetic legacy. The present study identified a family with primary manifestation of sinus bradycardia (five individuals) along with early repolarization (four individuals) and atrial fibrillation (one individual). Targeted exome sequencing was used to screen exons and adjacent splice sites of 61 inherited arrhythmia-associated genes, to detect pathogenic genes and variant sites in the proband. Family members were sequenced by Sanger sequencing and protein functions predicted by Polyphen-2 software. A total of three rare variants were identified in the family, including two missense variants in calcium voltage-gated channel subunit alpha1 C (CACNA1C) (gi:193788541, NM_001129843), c.1786G>A (p.V596M) and c.5344G>A (p.A1782T), and one missense variant in titin (TTN) c.49415G>A (p.R16472H) (gi:291045222, NM_003319). The variants p.V596M and p.R16472H were predicted to be deleterious and resulted in alterations in the amino acid type and sequence of the polypeptide chain, which may partially or completely inactivate the encoded protein. The comparison of literature, gene database, and pedigree phenotype analysis suggests that p.V596M or p.R16472H variants are pathogenic. The complex overlapping variants at three loci lead to a more severe phenotype in the proband, and may increase the susceptibility of individuals to atrial fibrillation. The simultaneous occurrence of V596M and R16472H may increase the severity of early repolarization. Various family members may have carried heterozygous mutants of p.A1782T and p.R16472H due to genetic heterogeneity, however did not exhibit clinical signs of cardiac electrophysiological alterations, potentially attributable to the low vagal tone. To the best of the author's knowledge, this is the first study to suggest the involvement of the novel missense CACNA1C c.1786G>A and TTN c.49415G>A variants in the inheritance of symptomatic bradycardia and development of SSS. PMID- 29568938 TI - FSCN-1 increases doxorubicin resistance in hepatocellular carcinoma through promotion of epithelial-mesenchymal transition. AB - Resistance to chemotherapy drugs remains a significant problem for the treatment of many types of cancer. Fascin-1 (FSCN-1) is an actin-bundling protein involved in the invasion and metastasis of a variety of tumors. However, its involvement in drug resistance in hepatocellular carcinoma (HCC) remains unclear. The present study aimed to investigate the function of FSCN-1 in HCC resistance to doxorubicin (DOX). FSCN-1 expression was increased in DOX-resistant HCC cell lines (SNU449 and SNU387) compared with DOX-sensitive cell lines (Huh7 and Hep3B). The resistance of HCC cells to DOX was decreased following FSCN-1 knockdown with small interfering RNA. FSCN-1 knockdown also significantly altered the expression of key markers of epithelial-mesenchymal transition (EMT). Notably, vimentin expression was reduced and epithelial-cadherin expression was increased. Furthermore, when EMT was suppressed through knockdown of Twist, an essential pathway of DOX-induced EMT, the viability of HCC cells following treatment with DOX was not affected by FSCN-1 expression. Furthermore, FSCN-1 knockdown eliminated hypoxia-induced doxorubicin resistance and EMT. The results of the present study indicated that FSCN-1 expression increased DOX resistance in HCC cells via the promotion of EMT, and this phenomenon was maintained in a hypoxic environment. FSCN-1 potentially represents a novel target to overcome resistance to DOX in HCC. PMID- 29568939 TI - Puerarin reduces ischemia/reperfusion-induced myocardial injury in diabetic rats via upregulation of vascular endothelial growth factor A/angiotensin-1 and suppression of apoptosis. AB - Puerarin is an active ingredient of pueraria, which has been developed for puerarin injections, used in the treatment of cardiovascular diseases including arrhythmia, myocardial ischemia and hypertension. However, the molecular mechanisms of puerarin on ischemia/reperfusion (I/R)-induced myocardial apoptosis in diabetic rats are not fully understood. The present study aimed to investigate whether puerarin can attenuate I/R-induced myocardial apoptosis in diabetic rats, and to investigate the underlying mechanism. A hemodynamic analyzing system was employed to analyze the left ventricular developed pressure (LVDP), the left ventricular end-systolic interior dimension (LVIDs) and the left ventricular end diastolic interior dimension (LVIDd). ELISA kits were used to analyze malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6 levels, NO production and caspase-3 activity. Nuclear factor (NF)-kappaB, ascular endothelial growth factor A (VEGFA), angiotensin (Ang)-I, phosphorylated (p)-endothelial nitric oxide synthase protein expression was analyzed using western blot analysis. Puerarin significantly reduced the myocardial infarct area, and increased left ventricular developed pressure in diabetic rats with myocardial I/R. Oxidative stress, inflammation and nuclear factor-kappaB protein expression were significantly reduced by puerarin. Furthermore, puerarin activated the protein expression levels of VEGFA and Ang-I, and increased nitric oxide production, phosphorylated-endothelial nitric oxide synthase protein expression and caspase-3 activity. These results demonstrated that the myocardial protective effect of puerarin serves to reduce myocardial I/R injury, via upregulation of VEGFA/Ang-1 and suppression of apoptosis, in diabetic rats with myocardial I/R. PMID- 29568940 TI - Ameliorative effect of nicergoline on cognitive function through the PI3K/AKT signaling pathway in mouse models of Alzheimer's disease. AB - Alzheimer's disease is one of the most common age-associated diseases that frequently leads to memory disorders, cognitive decline and dementia. Evidence suggests that nicergoline serves an important role in the apoptosis of hippocampal cells, memory recovery, cognitive function and neuronal survival. However, the signaling pathway affected by nicergoline treatment remains to be elucidated. The purpose of the present study was to investigate the role of nicergoline in the cognitive competence of a mouse model of Alzheimer's disease. The apoptosis rates of hippocampal cells were studied in mice with Alzheimer's disease treated with nicergoline compared with the negative control. Apoptosis associated gene expression levels in hippocampal cells, and hippocampus area, were analyzed in the experimental mice. Visual attention and inhibitory control were assessed and neural counting was performed in brain regions of interest. The phosphatidylinositol 3-kinase (PI3K)/RAC-alpha serine/threonine-protein kinase (AKT) signaling pathway was additionally analyzed in hippocampal cells following treatment with nicergoline. The results of the present study demonstrated that nicergoline ameliorated apoptosis in hippocampal cells and hippocampus tissue in 3xTg-AD mice with Alzheimer's disease. The data indicated that apoptosis associated genes, including caspase-3, BCL2 associated X, BH3 interacting domain death agonist and caspase-9, were downregulated in hippocampal cells isolated from nicergoline-treated experimental mice. In addition, the expression levels of inflammatory factors, in addition to oxidative stress, were decreased in hippocampal cells treated with nicergoline. Additionally, amyloid precursor protein accumulation was cleared in the hippocampal area in nicergoline-treated mice. Nicergoline inhibited neuronal loss and prevented cognitive impairment through the restoration of learning/memory ability. It was additionally demonstrated in the present study that nicergoline improved motor attention impairment and cognitive competence in hippocampal cells by acting on the PI3K/AKT signaling pathway. Therefore, memory recovery, cognitive function and neuronal survival were repaired by nicergoline via inhibition of the PI3K/AKT signaling pathway, suggesting that nicergoline may be an efficient drug for the clinical treatment of patients with Alzheimer's disease. PMID- 29568941 TI - Bradykinin potentially stimulates cell proliferation in rabbit corneal endothelial cells through the ZO-1/ZONAB pathway. AB - Bradykinin (BK) has been demonstrated to induce proliferation in several types of cell in ex vivo corneas. However, the mechanisms underlying the action of BK on corneal endothelial cells (CECs) remain largely unknown. The present study aimed to investigate the effect of BK on rabbit corneal endothelial cell (RCEC) proliferation, and assess the involvement of the zonula occludens-1(ZO-1)/ZO 1associated nucleic acid binding protein (ZONAB) pathway. Cell proliferation and cell cycle distribution was analyzed following treatment with BK (0.01, 0.1,1.0 or 10.0 uM) for the indicated time intervals (24, 48, 72 and 96 h), or following BK treatment combined with transfection of ZONAB-small interfering (si)RNA for 72 h. In addition, the expression of tight junction ZO-1, nuclear ZONAB, proliferating cell nuclear antigen(PCNA) and cyclin D1 were evaluated using western blotting or immunofluorescence. BK treatment was demonstrated to induce time- and concentration-dependent cell proliferation and cell cycle progression, along with the upregulation of tight junction ZO-1 and nuclear ZONAB, as well as PCNA and cyclin D1 protein expression. Furthermore, knockdown with ZONAB-siRNA inhibited cell proliferation, induced cell cycle arrest and downregulated PCNA and cyclin D1 protein expression. ZONAB knockdown therefore successfully reversed the increase in proliferation induced by BK treatment. Taken together, these results suggested that BK stimulated RCEC proliferation, potentially via the ZO 1/ZONAB pathway. The signaling paradigm disclosed in the present study potentially serves as an important therapeutic target for cornea regeneration and transplantation. PMID- 29568942 TI - Secoisolariciresinol diglucoside prevents the oxidative stress-induced apoptosis of myocardial cells through activation of the JAK2/STAT3 signaling pathway. AB - Myocardial cell apoptosis mediated by oxidative stress has previously been identified as a key process in ischemic heart disease. Secoisolariciresinol diglucoside (SDG), a polyphenolic plant lignan primarily found in flaxseed, has been demonstrated to effectively protect myocardial cells from apoptosis. In the present study, the role of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) was investigated in mediating the protective effect of SDG. Findings of the present study revealed that treatment with H2O2 reduced cell viability and induced apoptosis in H9C2 rat cardiomyocytes. However, SDG was able to reduce the effect of H2O2 in a dose-dependent manner. H2O2 reduced the expression level of phosphorylated STAT3 and inhibited the levels of B-cell lymphoma-extra-large and induced myeloid leukemia cell differentiation protein, which are the STAT3 target genes. Conversely, SDG rescued phosphorylation of STAT3 and increased the levels of STAT3 target genes. Treatment with SDG alone led to a dose-dependent increased phosphorylation of JAK2 and STAT3, without activating Src. Furthermore, the anti-apoptotic effects of SDG were partially abolished by a JAK2/STAT3 inhibitor. In addition, molecular docking revealed that SDG may bind to the protein kinase domain of JAK2, at a binding energy of -8.258 kcal/mol. Molecular dynamics simulations revealed that JAK2-SDG binding was stable. In conclusion, activation of the JAK2/STAT3 signaling pathway contributed to the anti-apoptotic activity of SDG, which may be a potential JAK2 activator. PMID- 29568943 TI - Identification of aberrantly expressed long non-coding RNAs in postmenopausal osteoporosis. AB - Postmenopausal osteoporosis (PMOP) is a common skeletal disorder in postmenopausal women. The present study aimed to identify the key long non-coding RNAs (lncRNAs) in PMOP through RNA sequencing. RNA sequencing was performed to obtain the expression profile of lncRNAs and mRNAs in blood samples of patients with PMOP and normal controls (NCs). Following the identification of differentially expressed mRNAs (DEmRNAs) and differentially expressed lncRNAs (DElncRNAs), the DElncRNA-DEmRNA co-expression network was constructed. A search was performed for the DEGs transcribed within a 100-kb window upstream or downstream of DElncRNAs, which served as nearby DEmRNAs of DElncRNAs. Functional annotation of the DEmRNAs co-expressed with DElncRNAs was performed. The GSE56815 dataset was used to verify the expression of selected DEmRNAs and DElncRNAs. Three blood samples from patients with PMOP and two blood samples from NCs were used for RNA sequencing. Compared with the NC group, a total of 185 DEmRNAs and 51 DElncRNAs were obtained in PMOP. A total of 3,057 co-expression DElncRNA DEmRNA pairs and 97 DElncRNA-nearby DEmRNA pairs were obtained. Six DEmRNAs [diacylglycerol O-acyltransferase 2, potassium voltage-gated channel subfamily S member 1, peptidase inhibitor 3, secretory leukocyte peptidase inhibitor, galectin-related protein and alkaline phosphatase, liver/bone/kidney (ALPL)] were nearby co-expressed genes of four DElncRNAs, including LOC105376834, LOC101929866, LOC105374771 and LOC100506113. Three PMOP-associated DEmRNAs, including ALPL, suppressor of cytokine signaling 3 and adrenomedullin, were co expressed with the hub DElncRNAs (LINC00963, LOC105378415, LOC105377067, HCG27, LOC101928143 and LINC01094) of the positively and negatively co-expressed DElncRNA-DEmRNA interaction network. The expression of selected DEmRNAs and DElncRNAs was consistent with the RNA-sequencing results. In conclusion, the present study identified the key DEmRNAs and DElncRNAs in PMOP, which may provide clues for understanding the mechanism and developing novel biomarkers for PMOP. PMID- 29568945 TI - Asparaginyl endopeptidase enhances pancreatic ductal adenocarcinoma cell invasion in an exosome-dependent manner and correlates with poor prognosis. AB - Pancreatic cancer is one of the most lethal types of cancer; owing to low early detection rates and high metastasis rates, it is associated with an extremely poor prognosis. Therefore, a better understanding of the molecular mechanisms that underlie its metastasis and the identification of potential prognostic biomarkers are urgently required. Although high expression levels of asparaginyl endopeptidase (AEP) have been detected in various types of solid tumor, the expression and functions of AEP in pancreatic carcinomas have yet to be determined. The present study aimed to examine the putative functions of AEP in pancreatic carcinoma. Immunohistochemical analysis revealed that AEP was highly expressed in pancreatic cancer tissues compared with adjacent normal tissues. Patients with high AEP expression exhibited a significantly shorter overall survival time. Results from multivariate Cox regression analysis revealed that AEP was an independent prognostic factor for overall survival. Gain- and loss-of function experiments demonstrated that knockdown of AEP expression significantly reduced the invasive ability of pancreatic cancer cells, whereas overexpression of AEP increased the invasive ability. In addition, AEP was detected in exosomes that were derived from cultured pancreatic ductal adenocarcinoma cells (PDACs) and in the serum from patients with PDAC. The Matrigel-Transwell invasion assay revealed that exosomes enriched with AEP were able to enhance the invasive ability of PDAC cells, whereas exosomes lacking AEP decreased the invasive ability. Furthermore, results from the present study suggested that AEP may be crucial for activation of the phosphoinositide 3-kinase/RAC-alpha serine/threonine-protein kinase signaling pathway in PDAC cells. The present study data indicated that high AEP expression may be important for pancreatic carcinoma progression in an exosome-dependent manner, and that AEP may be an independent indicator of poor prognosis in patients with PDAC and may be a novel prognostic biomarker or therapeutic target in pancreatic carcinoma. PMID- 29568944 TI - PEDF regulates lipid metabolism and reduces apoptosis in hypoxic H9c2 cells by inducing autophagy related 5-mediated autophagy via PEDF-R. AB - Pigment epithelial-derived factor (PEDF) is a multifunctional secreted glycoprotein, which exerts a variety of physiological activities. PEDF may protect against hypoxia-induced cell death associated with its antioxidative effects and p53 mitochondrial translocation in cultured cardiomyocytes and H9c2 cells. Additionally, previous studies have suggested that autophagy is an important cell survival mechanism. However, the effect of PEDF on autophagy and the associated pathway in hypoxic H9c2 cells has not been fully established. Autophagy has been reported to regulate lipid metabolism; however, little is known about whether PEDF is able to regulate lipid metabolism by promoting autophagy. In the present study, western blotting results revealed that PEDF increased the level of microtubule-associated protein 1A/1B-light chain 3 (LC3) II. Transmission electron microscopy (TEM) and LC3 fluorescence demonstrated that PEDF increased the number of autophagosomes. PEDF also increased the viability of hypoxic H9c2 cells and decreased the level of cleaved caspase-3 protein, as evidenced by CCK-8 assays and western blotting, respectively. TEM and a triglyceride assay kit demonstrated that PEDF-induced autophagy may stimulate lipid degradation. Western blotting results revealed a novel mechanism underlying PEDF-induced H9c2 cell autophagy via the PEDF-R-mediated Atg5 pathway under hypoxic conditions. Furthermore, the results also suggest that PEDF-induced autophagy may stimulate lipid degradation. The survival function of autophagy suggests that modulation of PEDF-induced autophagy may be used as a therapeutic strategy to protect cells against lipid-associated metabolic diseases.

AB - Malignant melanoma (MM) is caused by melanophore cancerization in tissue pigmentation regions, leading to skin, mucous membrane, eye and central nervous system carcinogenesis. The incidence of MM has increased in previous years, and it has become the primary cause of skin cancer-associated mortality in developed countries. MM is characterized as highly malignant and readily metastasized, and has a poor prognosis. Targeting angiogenesis is an important method for MM treatment. As an important proangiogenic factor in tumor growth and metastasis, vascular endothelial growth factor (VEGF) can promote neovascularization and increase vascular permeability. Gefitinib is a novel drug targeting VEGF. The effect and mechanism of gefitinib on MM remain to be elucidated, and were investigated in the present study. The A375 MM cell line was used in the present study; it was cultured in vitro and divided into gefitinib groups (5 and 10 uM) and a control group. Cell proliferation was measured using an MTT assay and the activity of caspase-3 was assessed using a kit. Cell invasive ability was determined using a Transwell chamber. The mRNA and protein expression levels of VEGF and AKT were detected using reverse transcription-quantitative polymerase chain reaction and western blot analyses. Gefitinib significantly inhibited MM cell proliferation, enhanced the activity of caspase 3 and suppressed tumor cell invasion (P<0.05). In addition, gefitinib significantly downregulated the mRNA and protein expression levels of VEGF and AKT, and these changes were dose dependent (P<0.05). Taken together, gefitinib suppressed MM cell proliferation and invasion in vitro by regulating the VEGF/AKT signaling pathway. PMID- 29568948 TI - Overexpression of collagen type V alpha1 chain in human breast invasive ductal carcinoma is mediated by TGF-beta1. AB - Collagen type V alpha1 chain (COL5A1) is a minor fibrillar collagen in mammals that co-polymerizes with type I collagen to adjust the diameter of collagen molecules. However, the function of COL5A1 in invasive ductal carcinoma (IDC) of the human breast remains unknown. In the present study, our group examined the expression of COL5A1 in IDC compared with its adjacent normal tissue and fibroadenoma of the breast. COL5A1 was revealed to be overexpressed in IDC compared with benign tumor and adjacent normal control tissues, and was associated with the expression of estrogen receptor and progesterone receptor. No association between COL5A1 expression and tumor size, lymph node metastasis, clinical stage, age, or Her2 expression was identified. High expression of COL5A1 mRNA was associated with distant metastasis free survival in patients with breast cancer. Knockdown of COL5A1 led to a decrease of cell viability, as detected by the WST-1 assay, and an inhibition of migration and invasion, as detected by wound healing and Transwell assays, respectively, in the breast cancer cell line MCF-7. The expression of COL5A1 in MCF-7 cells was downregulated by transforming growth factor (TGF)-beta1, which was abolished in the presence of SB-431542, an inhibitor of TGF-beta type I receptor. In conclusion, these data indicated that COL5A1 is overexpressed in IDC and regulated by TGF-beta1, suggesting that an increase of COL5A1 reflects tumor progression and may serve as a novel biomarker and therapeutic target for the treatment of breast IDC. PMID- 29568947 TI - Low molecular weight fucoidan attenuates experimental abdominal aortic aneurysm through interfering the leukocyte-endothelial cells interaction. AB - Low molecular weight fucoidan (LMWF) is a sulfated polysaccharide extracted from Saccharina Japonica that presents high affinity for P-selectin and abolish selectin-dependent recruitment of leukocytes. We hypothesized that dietary intake of LMWF, as a competitive binding agent of P-selectin, could limit the inflammatory infiltration and aneurysmal growth in an Angiotensin II-induced abdominal aortic aneurysm (AAA) mouse model. The Gene Expression Omnibus database was used for gene expressions and gene set enrichment analysis. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that focal adhesion was involved in the development of AAA. However, dietary intake of LMWF could limit the enlargement of AAA, decreasing maximal aortic diameter and preserving elastin lamellae. Although LMWF did not decrease the circulatory monocytes count and lower the expression of P-selectin in endothelium, it reduced macrophages infiltration in media and adventitia. Furthermore, matrix metalloproteinase expression was markedly downregulated, accompanied with reduced expression of inflammatory mediators, including interleukin 1beta, tumor necrosis factor-alpha and monocyte chemotactic protein-1. The present study revealed a novel target for the treatment of AAA and the anti-inflammatory effects of LMWF. PMID- 29568949 TI - Pyrroloquinoline quinone induces chondrosarcoma cell apoptosis by increasing intracellular reactive oxygen species. AB - Pyrroloquinoline quinone (PQQ) has been reported to contribute to cancer cell apoptosis and death; however, little is known of its underlying mechanisms. The present study was designed to investigate the role of PQQ in chondrosarcoma cell apoptosis and the underlying mechanism. A cell cytotoxicity assay was used to detect cell death; flow cytometry analysis was also performed to determine cell apoptosis and intracellular reactive oxygen species (ROS). Biochemical methods were employed to detect the activity and the expression of superoxide dismutase (SOD)1, SOD2 and glutathione. The present study also examined the effect on tumorigenesis in vivo. The results demonstrated that the apoptosis of SW1353 cells induced by PQQ increased in a concentration- and time-dependent manner, which may be attributable to the accumulation of intracellular ROS. In the in vivo experiments, PQQ inhibited proliferation and promoted apoptosis, increased ROS levels and caused DNA damage in transplanted cells. Taken together, the findings of the present study confirmed that PQQ induced apoptosis in human chondrosarcoma SW1353 cells and transplanted cells, by increasing intracellular ROS and reducing the ability of scavenging oxygen free radicals. PMID- 29568950 TI - Genistein inhibits invasion and migration of colon cancer cells by recovering WIF1 expression. AB - Colon cancer is characterized by invasion and migration. DNA methylation of CpG islands in tumor suppressor genes is considered to be an epigenetic mechanism underlying cancer development. Epigenetic silencing of a gene may be reversed by drugs, including genistein. The present study aimed to determine the effect of genistein on Wnt inhibitory factor 1 (WIF1) and invasion, and migration of colon cancer cells. The viability of HT29 colon cancer cells was suppressed by genistein in a dose dependent manner. Following 72 h of treatment with 10, 20 and 60 umol/l genistein, increased demethylation of WIF1 was induced in a dose dependent manner. Additionally, the invasive/migratory abilities of cells treated with genistein decreased in a dose-dependent manner. Reverse transcription quantitative polymerase chain reaction and western blot analyses were performed to identify the mRNA and protein expression levels of invasion/migration associated factors. Following treatment with genistein, matrix metalloproteinase (MMP) 2 and MMP9 expression levels decreased, whereas the expression of metalloproteinase inhibitor 1 and E-cadherin increased significantly. In addition, the expression levels of proto-oncogene Wnt-1 (Wnt-1)/beta-catenin pathway-associated factors, beta-catenin, c-Myc proto-oncogene protein and cyclin D1 decreased in a dose-dependent manner following treatment with genistein. The invasive/migratory abilities of cells transfected with WIF1-small interfering (si) RNA, and those transfected with WIF1-siRNA and treated with genistein, increased notably compared with the control group. The present study demonstrated that genistein was able to inhibit the cell invasion and migration of colon cancer cells by inducing demethylation, and recovering the activity of WIF1 by altering the expression of invasion-associated factors, and components of the Wnt signaling pathway. PMID- 29568951 TI - Effect of liposome-mediated HSP27 transfection on collagen synthesis in alveolar type II epithelial cells. AB - To investigate the effect of liposome Lipofectamine(r) 2000-mediated HSP27 plasmid transfection in A549 human alveolar type II epithelial cell line on collagen synthesis during transforming growth factor-beta1 (TGF-beta1)-induced type II epithelial cell transition to myofibroblasts. Cells were transfected with varying ratios of the Lipofectamine(r) 2000-mediated heat shock protein 27 (HSP27) plasmid and the transfection efficiency was determined using flow cytometry. The maximum transfection efficacy was confirmed by laser confocal microscopy. HSP gene expression and the most efficient HSP27 plasmid were determined using reverse transcription-quantitative polymerase chain reaction. Western blot analysis was used to examine HSP27 and collagen expression levels. With a transfection efficiency of 83%, the 8 ug:20 ul ratio of liposome: Plasmid had the highest transfection levels. Among the four different interference sequences in the HSP27 plasmid, the D sequence had the highest interference effect with 70% silencing of the HSP27 gene. The expression of type I and III collagen in TGF-beta1-induced transition of A549 human alveolar type II epithelial cell line to myofibroblasts was significantly downregulated by the successful transfection with HSP27-interfering plasmid. The expression of type I and III collagen in the TGF-beta1-induced transition of A549 cells to myofibroblasts was significantly downregulated by transfection of A549 cells with HSP27 plasmid D-interfering sequence and optimal ratio of Lipofectamine(r) 2000 and HSP27 plasmid. PMID- 29568952 TI - Whole exome sequencing identifies novel candidate mutations in a Chinese family with left ventricular noncompaction. AB - Left ventricular noncompaction (LVNC) is an inherited cardiomyopathy involving numerous genes. To identify novel candidate causal mutations, a whole exome sequencing study was performed on a Chinese LVNC family. Exons of the most prevalent pathogenic genes of LVNC (myosin heavy chain 7 and actin, alpha-cardiac muscle 1) were sequenced, although no mutations were identified. Following this, Burrows-Wheeler Aligner, PICARD and Genome Analysis Toolkit (v.2.8) were used to analyze the exome sequencing data. Non-silent single nucleotide variants (SNVs) that were identified in patients with LVNC, although not in the healthy individual, were investigated further using SNV prioritization via the integration of genomic data (SPRING) based on P-values. Co-expressed gene enrichment analysis was performed using Genotype Tissue Expression (GTEx) data in order to investigate the potential roles of the genes containing SNVs in the myocardium. In the Chinese LVNC family, seven novel SNVs were identified that were only present in patients with LVNC and annotated by SPRING with P<0.05. Among these SNVs, hemicentin 1 [c. thymine (T) 9776 cytosine (C)], tolloid like 2 [c. cytosine (C) 2615 thymine (T)], fms related tyrosine kinase 3 [c. guanine (G) 976 adenine (A)] and nucleotide binding protein like [c. guanine (G) 91 thymine (T)] were located in conserved regions and annotated as deleterious by PolyPhen2, LRT and MutationTaster database analyses. Based on GTEx data, it was revealed that NUBPL was co-expressed with almost all previously established LVNC pathogenic genes. Furthermore, the results of the present study demonstrated that genes co-expressed with NUBPL were additionally enriched in the Notch signaling pathway. In addition, the results revealed numerous novel mutations that may be causal SNVs for the development of LVNC in the family involved in the present study. PMID- 29568953 TI - Comparison of mouse brown and white adipose-derived stem cell differentiation into pacemaker-like cells induced by TBX18 transduction. AB - The present study aimed to compare brown adipose-derived stem cell (BASC) and white adipose-derived stem cell (WASC) differentiation into pacemaker-like cells following T-box (TBX)18 transduction. Mouse BASCs and WASCs were induced to differentiate into pacemaker-like cells by adenovirus-TBX18 transduction in vitro. The transduction rate was determined by fluorescence microscopy and cell ultrastructural changes were observed by transmission electron microscopy at 48 h post-transduction. The mRNA and protein expression of pacemaker cell-associated markers, including TBX18, TBX3, sarcomeric alpha-actinin (Sr) and hyperpolarization-activated cyclic nucleotide-gated channel 4 (HCN4), were detected by reverse transcription-quantitative polymerase chain reaction, immunofluorescence staining and western blot analysis. The results demonstrated that no significant difference was observed in the transduction rate between BASCs and WASCs. The ultrastructure of BASCs was observed to be more complex than that of WASCs, indicating that BASCs may possess a better structural foundation to differentiate into pacemaker-like cells. TBX18, TBX3, Sr and HCN4 mRNA and protein expression in differentiated stem cells was significantly increased compared with the respective control groups. Furthermore, the expression levels were significantly higher in TBX18-BASCs compared with TBX18-WASCs. In conclusion, TBX18 gene transduction may facilitate the differentiation of BASCs and WASCs into pacemaker-like myocardial cells, and BASCs may have a higher capacity than WASCs for this differentiation. TBX18 gene may therefore act as an efficient candidate in cell transplantation therapy for diseases and for future research into the cardiovascular system. PMID- 29568954 TI - Tranilast prevents renal interstitial fibrosis by blocking mast cell infiltration in a rat model of diabetic kidney disease. AB - Renal interstitial fibrosis is a final pathway that is observed in various types of kidney diseases, including diabetic kidney disease (DKD). The present study investigated the effect of tranilast on renal interstitial fibrosis and the association between its role and mast cell infiltration in a rat model of DKD. A total of 30 healthy 6-week-old male Sprague-Dawley rats were randomly divided into the following four groups: Normal control group; DKD model group; low-dose tranilast group (200 mg/kg/day); and high-dose tranilast group (400 mg/kg/day). The morphological alterations of tubulointerstitial fibrosis were evaluated by Masson's trichrome staining, while mast cell infiltration into the renal tubular interstitium was measured by toluidine blue staining and complement C3a receptor 1 (C3aR) immunohistochemical staining (IHC). The expression of fibronectin (FN), collagen I (Col-I), stem cell factor (SCF) and proto-oncogene c-kit (c-kit) was detected by IHC, western blotting and reverse transcription-quantitative polymerase chain reaction. The results demonstrated that tubulointerstitial fibrosis and mast cell infiltration were observed in DKD model rats, and this was improved dose-dependently in the tranilast treatment groups. The expression of FN, Col-I, SCF and c-kit mRNA and protein was upregulated in the tubulointerstitium of DKD model rats compared with the normal control rats, and tranilast inhibited the upregulated expression of these markers. Furthermore, the degree of SCF and c-kit expression demonstrated a significant positive correlation with C3aR-positive mast cells and the markers of renal interstitial fibrosis. The results of the present study indicate that mast cell infiltration may promote renal interstitial fibrosis via the SCF/c-kit signaling pathway. Tranilast may prevent renal interstitial fibrosis through inhibition of mast cell infiltration mediated through the SCF/c-kit signaling pathway. PMID- 29568955 TI - hTERT peptide fragment GV1001 demonstrates radioprotective and antifibrotic effects through suppression of TGF-beta signaling. AB - GV1001 is a 16-amino acid peptide derived from the human telomerase reverse transcriptase (hTERT) protein (616-626; EARPALLTSRLRFIPK), which lies within the reverse transcriptase domain. Originally developed as an anticancer vaccine, GV1001 demonstrates diverse cellular effects, including anti-inflammatory, tumor suppressive and antiviral effects. In the present study, the radioprotective and antifibrotic effects of GV1001 were demonstrated through suppressing transforming growth factor-beta (TGF-beta) signaling. Proliferating human keratinocytes underwent premature senescence upon exposure to ionizing radiation (IR), however, treatment of cells with GV1001 allowed the cells to proliferate and showed a reduction in senescent phenotype. GV1001 treatment notably increased the levels of Grainyhead-like 2 and phosphorylated (p-)Akt (Ser473), and reduced the activation of p53 and the level of p21/WAF1 in irradiated keratinocytes. It also markedly suppressed the level of TGF-beta signaling molecules, including p-small mothers against decapentaplegic (Smad)2/3 and Smad4, and TGF-beta target genes, including zinc finger E-box binding homeobox 1, fibronectin, N-cadharin and Snail, in irradiated keratinocytes. Furthermore, GV1001 suppressed TGF-beta signaling in primary human fibroblasts and inhibited myofibroblast differentiation. Chromatin immunoprecipitation revealed that GV1001 suppressed the binding of Smad2 on the promoter regions of collagen type III alpha1 chain (Col3a1) and Col1a1. In a dermal fibrosis model in vivo, GV1001 treatment notably reduced the thickness of fibrotic lesions and the synthesis of Col3a1. These data indicated that GV1001 ameliorated the IR-induced senescence phenotype and tissue fibrosis by inhibiting TGF-beta signaling and may have therapeutic effects on radiation-induced tissue damage. PMID- 29568957 TI - [Retracted] Rivaroxaban attenuates thrombosis by targeting the NF-kappaB signaling pathway in a rat model of deep venous thrombus. AB - Following the publication of this article, an interested reader made us aware that the authors of the above paper had misappropriated certain of the data that had been published previously in three different papers. Specifically, Fig. 2A, B and G in the above paper appeared to be derived from Figs. 2A, 3 and 1A, respectively, of the paper by CM Ripplinger, CW Kessinger, C Li, JW Kim, JR McCarthy, R Weissleder, PK Henke, CP Lin and FA Jaffer (Arterioscler Thromb Vasc Biol 32: 2616-2624, 2012). Figs. 2E, F, H, I and J in the above paper appeared to be derived from Figs. 1, 2A, 2D, 5E and 3F, respectively, of the paper by ML von Bruhl, K Stark, A Steinhart, S Chandraratne, I Konrad, M Lorenz, A Khandoga, A Tirniceriu, R Coletti, M Kollnberger, et al (J Exp Med 209: 819-835, 2012).

PMID- 29568956 TI - Genome-wide transcriptional analysis of BRD4-regulated genes and pathways in human glioma U251 cells. AB - Bromodomain containing 4 (BRD4), a member of the bromodomain and extra-terminal family, has become a promising drug target for numerous types of cancer. BRD4 has been reported to be deregulated in gliomas; however, the precise molecular pathways regulated by BRD4 remained elusive. In the present study, BRD4 expression was silenced in the glioma cell line U251 and the results demonstrated that BRD4 knockdown attenuated cell proliferation and promoted cell apoptosis. A genome-wide analysis of BRD4-regulated transcripts in U251 cells was performed using microarray to reveal the possible molecular mechanism. A total of 3,529 differentially expressed genes were identified; 1,648 of these genes were upregulated and 1,881 were downregulated. The results of the gene ontology analysis revealed that these genes were mainly involved in membrane organization, mitotic cell cycle, cell division and DNA replication. Pathway analysis revealed that the pathways altered following BRD4 knockdown included multiple cellular processes, such as cell cycle and apoptosis. Candidate genes were identified through global signal transduction network analysis and were validated using reverse transcription-quantitative polymerase chain reaction and western blot analyses. The results demonstrated that BRD4 knockdown decreased the expression of KRAS proto-oncogene GTPase (KRAS). Downregulated KRAS expression in U251 cells restrained cell proliferation and promoted cell apoptosis, suggesting that the effect of BRD4 on glioma cells might occur through the Ras pathway. In conclusion, the present results confirmed the role of BRD4 in glioma and provided information for further exploration of the molecular mechanism of BRD4 in glioma development and progression. PMID- 29568958 TI - Dexmedetomidine attenuates H2O2-induced neonatal rat cardiomyocytes apoptosis through mitochondria- and ER-medicated oxidative stress pathways. AB - Dexmedetomidine (DEX), an alpha2 adrenoceptor agonist, has sedative and analgesic properties and myocardial protective effects. However, the mechanism underlying the protective effects of DEX on the myocardium remain unclear. The present study aimed to determine whether DEX serves an important role on cardioprotection through the endoplasmic reticulum (ER)- and mitochondria-mediated apoptosis signaling pathways. Neonatal rat cardiomyocytes (NRCMs) were cultured and divided four groups: i) Normal culture medium with 10% fetal bovine serum (control group); ii) H2O2 at 500 uM (H2O2 group); iii) DEX at 5 uM (DEX group); and iv) H2O2 plus DEX (H2O2 + DEX group). The levels of apoptosis and oxidative stress of NRCMs were investigated by ELISA, western blotting, flow cytometry and cell immunofluorescence. DEX significantly suppressed H2O2-induced apoptosis, and increased activity of caspases 3, 8 and 9 of NRCMs. DEX inhibited mitochondria mediated oxidative stress and apoptosis, as evidenced by decreased levels of reactive oxygen species and lactic dehydrogenase, alleviated mitochondrial membrane potential depolarization, and increased Bcl-2-associated X protein/B cell lymphoma 2 ratio. In addition, DEX decreased the activity of caspase 12, and the expression levels of glucose-regulated protein 78 kDa and serine/threonine protein kinase/endoribonuclease IRE1, three major signaling molecules involved in the ER stress-mediated apoptosis pathway. Preventive treatment with DEX alleviates cardiomyocyte against H2O2-induced oxidative stress injury through attenuating the mitochondria- and ER-mediated apoptosis pathways. PMID- 29568959 TI - Ethoxysanguinarine inhibits viability and induces apoptosis of colorectal cancer cells by inhibiting CIP2A. AB - Cancerous inhibitor of protein phosphatase 2A (CIP2A) an endogenous inhibitor of protein phosphatase 2A (PP2A), which can promote proliferation and transformation of several cancer types, has been shown to be a target for tumor therapy. The present study investigated the effects and underlying mechanisms of action of a novel natural compound, ethoxysanguinarine (Eth), on colorectal cancer (CRC) cells. MTT assay and flow cytometric assay found that Eth inhibited the viability and induced the apoptosis of the CRC cells. The inhibition of viability and activation of apoptosis was mediated through the Eth-induced decrease in CIP2A expression. Knockdown of CIP2A by RNA interference sensitized, whereas overexpression of CIP2A antagonized, Eth-induced viability inhibition and apoptosis. Furthermore, western blot analysis suggested that Eth inhibited phosphorylation of CIP2A downstream molecule protein kinase B via the activation of PP2A. CRC xenograft tests also confirmed the antitumor effect of Eth in vivo. These results advance our understanding of Eth-induced viability inhibition and apoptosis, implying the requirement for further investigation of Eth as a CIP2A inhibitor for cancer therapies. PMID- 29568960 TI - Biphasic activation of nuclear factor-kappaB and expression of p65 and c-Rel following traumatic neuronal injury. AB - The transcription factor nuclear factor-kappaB (NF-kappaB) has been shown to function as a key regulator of cell death or survival in neuronal cells. Previous studies indicate that the biphasic activation of NF-kappaB occurs following experimental neonatal hypoxia-ischemia and subarachnoid hemorrhage. However, the comprehensive understanding of NF-kappaB activity following traumatic brain injury (TBI) is incomplete. In the current study, an in vitro model of TBI was designed to investigate the NF-kappaB activity and expression of p65 and c-Rel subunits following traumatic neuronal injury. Primary cultured neurons were assigned to control and transected groups. NF-kappaB activity was detected by electrophoretic mobility shift assay. Western blotting and immunofluorescence were used to investigate the expression and distribution of p65 and c-Rel. Reverse transcription-quantitative polymerase chain reaction was performed to assess the downstream genes of NF-kappaB. Lactate dehydrogenase (LDH) quantification and trypan blue staining were used to estimate the neuronal injury. Double peaks of elevated NF-kappaB activity were observed at 1 and 24 h following transection. The expression levels of downstream genes exhibited similar changes. The protein levels of p65 also presented double peaks while c Rel was elevated significantly in the late stage. The results of the trypan blue staining and LDH leakage assays indicated there was no sustained neuronal injury during the late peak of NF-kappaB activity. In conclusion, biphasic activation of NF-kappaB is induced following experimental traumatic neuronal injury. The elevation of p65 and c-Rel levels at different time periods suggests that within a single neuron, NF-kappaB may participate in different pathophysiological processes. PMID- 29568961 TI - Cytoprotective effects of diosmetin against hydrogen peroxide-induced L02 cell oxidative damage via activation of the Nrf2-ARE signaling pathway. AB - Oxidative stress is considered a crucial mediator in the pathogenesis of various liver diseases. The flavone diosmetin has been reported to exhibit antioxidant activities; however, the hepatoprotective effects of diosmetin against oxidative stress, and the underlying molecular mechanisms, remain unknown. The present study aimed to investigate the potential hepatoprotective effects of diosmetin on hydrogen peroxide (H2O2)-induced oxidative damage in L02 cells and attempted to evaluate the role of the nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element pathway in this process. L02 cells were divided into groups: Control (DMSO, diosmetin), H2O2, Trolox or tertiary butylhydroquinone and diosmetin (different doses). Protective effects in L02 cells were determined by CCK-8, cell apoptosis and lactate dehydrogenase leakage assays. Flow cytometry and inverted fluorescence microscope were used to measure the intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (MMP). Protein expression levels were of Nrf2, heme oxygenase-1 (HO-1) and NAD(P)H quinone oxidoreductase-1 (NQO1) were determined by western blotting and mRNA levels were determined by reverse transcription-quantitative polymerase chain reaction. The results revealed that H2O2 induced notable injury to L02 cells, as demonstrated by decreased cell viability, increased lactate dehydrogenase release, apoptotic rate and intracellular ROS production, and by the loss of MMP. Conversely, diosmetin (20-40 uM) significantly reversed the damaging effects of H2O2, which indicated that diosmetin may exhibit potent hepatoprotective potential against H2O2-induced oxidative damage. Furthermore, pretreatment with diosmetin elevated mRNA and protein expression levels of Nrf2, HO-1 and NQO1. The present study is the first, to the best of our knowledge, to demonstrate that activation of the Nrf2/NQO1-HO-1 signaling pathway maybe involved in the cytoprotective effects of diosmetin against oxidative stress. Therefore, diosmetin may be considered a promising therapeutic agent for the treatment of various liver diseases associated with oxidative stress. PMID- 29568962 TI - Dickkopf-3 upregulation mediates the cardioprotective effects of curcumin on chronic heart failure. AB - Curcumin, isolated from rhizome of turmeric, has been widely studied as a potential therapeutic drug for cancer. However, protective effects of curcumin on chronic heart failure (CHF) have not been fully studied. In the present study, the effects of curcumin on CHF and the underlying mechanisms were investigated. A total of 40 rabbits were randomized into 4 groups: Control rabbits fed with placebo (Con) or curcumin (Con-cur), CHF rabbits fed with placebo (CHF) or curcumin (CHF-cur). CHF was induced by volume and pressure overload. The effects of curcumin on cardiac function and left ventricular (LV) structure were assessed by echocardiography and histology. The effects of curcumin on CHF molecular biomarkers were detected by dihydroethidium and immunohistochemical staining. The effects of curcumin on Dickkopf-related protein 3 (DKK-3), p38 mitogen-activated protein kinase (p38), c-Jun N-terminal kinase (JNK) and apoptosis signal regulating kinase 1 (ASK1) were assessed by immunohistochemical staining and western blot analysis. Cardiac dysfunction and LV remodeling were successfully produced by ten weeks volume overload and eight weeks pressure overload in the CHF group. Compared with the Con group, the CHF group demonstrated higher levels of CHF molecular biomarkers, a lower level of DKK-3 expression and alterations of p38, JNK and ASK1 protein expression. Curcumin alleviated all those abnormalities markedly in the CHF-cur group. In summary, curcumin may exert cardioprotective effects by up-regulating DKK-3, which in turn may inhibit p38 and JNK signaling pathways in an ASK1-dependent way. The present study demonstrated that Dickkopf-3 upregulation mediates the cardioprotective effects of curcumin on chronic heart failure for the first time. PMID- 29568963 TI - Microarray analysis of the expression profile of lncRNAs reveals the key role of lncRNA BC088327 as an agonist to heregulin-1beta-induced cell proliferation in peripheral nerve injury. AB - Heregulin-1beta is capable of promoting the nerve regeneration of acellular nerve allografts with skin-derived precursor differentiated Schwann cell (SC) therapy in peripheral nerve injury. Long non-coding RNAs (lncRNAs) serve important roles in the regulation of gene transcription and trans-lation in multiple biological processes, but its association with the repair of peripheral nerve injury is unexplored. Therefore, in the present study, the aim was to identify novel indicators for peripheral nerve injury, and to detect whether there is an association between lncRNA expression and the treatment effect of heregulin-1beta on this disorder. The expression status of lncRNAs and mRNAs in a well-built rat model with sciatic nerve injury was investigated using microarray assays. Based on the results of the microarray assays and quantitative polymerase chain reaction validation, it was inferred that lncRNA BC088327 was upregulated to the largest extent among all the lncRNAs. According to these findings, the role of BC088327 in peripheral nerve injury was further assessed by detecting the cell viability, cell cycle and apoptosis in a hypoxic SC cell model after suppressing the expression of BC088327 using specific small interfering RNA. Based on the results of the lncRNA microarray assay, 805 lncRNAs were significantly differentially expressed, among which, 323 lncRNAs were upregulated and 482 lncRNAs were downregulated. Based on the results of the mRNA microarray assay, 1,293 lncRNAs were significantly differentially expressed, including 603 upregulated and 690 downregulated lncRNAs. Moreover, knockdown of lncRNA BC088327 suppressed cell viability and induced cell apoptosis and S-phase cell cycle arrest in the SCs. In conclusion, expression profile changes of lncRNAs in peripheral nerve injuries were closely associated with treatment with heregulin 1beta. lncRNA BC088327 may play a synergistic role with heregulin-1beta in repairing peripheral injury, which has the potential be a biomarker for the detection of peripheral injury and a medical target for the development of therapeutic modalities. PMID- 29568965 TI - Downregulation of lncRNA H19 inhibits the migration and invasion of melanoma cells by inactivating the NF-kappaB and PI3K/Akt signaling pathways. AB - As the most aggressive type of skin cancer, melanoma seriously affects human health. Long noncoding (lncRNA) 19 has been demonstrated to be involved in the progression of a number of different types of human cancers. However, the involvement of lncRNA H19 in melanoma remains unknown. Therefore, the present study was performed to investigate the roles of H19 in the development and progression of melanoma. In the present study, 49 patients with melanoma were included. Expression of lncRNA H19 in tumor tissue, adjacent healthy tissue and various cell lines with different treatments was measured by reverse transcription-quantitative polymerase chain reaction. The effects of H19 knockdown on melanoma cell proliferation, migration and invasion were detected by cell counting kit-8, wound-healing and transwell invasion assays, respectively. In addition, the effects of H19 knockdown on the expression of nuclear factor (NF)-kappaB pathway-associated proteins were investigated by western blotting. The results revealed that the expression level of H19 was significantly higher in tumor tissue than in the adjacent healthy tissue of 47 out of 49 patients. H19 knockdown significantly reduced the proliferation, migration and invasion ability of melanoma cells. H19 knockdown also inactivated the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) pathway, which in turn inhibited the activation of the NF-kappaB signaling pathway. Thus, downregulation of lncRNA H19 may inhibit the migration and invasion of melanoma cells by inactivating the NF-kappaB signaling pathway via the inactivation of the PI3K/Akt signaling pathway. The present study provided references for future studies on the pathogenesis of melanoma and the clinical treatment of this disease. PMID- 29568966 TI - PPP2R2D, a regulatory subunit of protein phosphatase 2A, promotes gastric cancer growth and metastasis via mechanistic target of rapamycin activation. AB - Protein phosphatase 2A (PP2A) is an essential serine/threonine protein phosphatase that regulates the basic activities of eukaryotes by dephosphorylating its substrates. The function and substrate specificity of PP2A are generally determined by its regulatory subunits. In the present study, the clinical significance and roles of PPP2R2D, one of the regulatory subunits of PP2A, were demonstrated in gastric cancer (GC) carcinogenesis. Through a tissue microarray and quantitative polymerase chain reaction analysis, it was demonstrated that PPP2R2D was commonly upregulated in GC samples. This upregulation was positively correlated with the patients' tumor stage (P<0.01), T classification (P<0.01) and N classification (P=0.01). Furthermore, a high expression of PPP2R2D was closely associated with poor prognosis of patients. Knockdown of PPP2R2D significantly inhibited the proliferation and migration of GC cells in vitro, as well as the tumorigenicity and metastasis in vivo in an animal GC model. By contrast, overexpression of PPP2R2D promoted GC cell proliferation and migration in vitro. The analysis of underlying mechanisms indicated that PPP2R2D silencing decreased the phosphorylation level of mechanistic target of rapamycin (mTOR), thereby implicating that PPP2R2D is involved in the regulation of mTOR activity during tumorigenesis. Thus, the findings of the present study suggested that PPP2R2D may serve as a potential oncogene in GC and as a novel target for therapeutic strategies against this disease. PMID- 29568964 TI - Disruption of IGF-1R signaling by a novel quinazoline derivative, HMJ-30, inhibits invasiveness and reverses epithelial-mesenchymal transition in osteosarcoma U-2 OS cells. AB - Osteosarcoma is the most common primary malignancy of the bone and is characterized by local invasion and distant metastasis. Over the past 20 years, long-term outcomes have reached a plateau even with aggressive therapy. Overexpression of insulin-like growth factor 1 receptor (IGF-1R) is associated with tumor proliferation, invasion and migration in osteosarcoma. In the present study, our group developed a novel quinazoline derivative, 6-fluoro-2-(3 fluorophenyl)-4-(cyanoanilino)quinazoline (HMJ-30), in order to disrupt IGF-1R signaling and tumor invasiveness in osteosarcoma U-2 OS cells. Molecular modeling, immune-precipitation, western blotting and phosphorylated protein kinase sandwich ELISA assays were used to confirm this hypothesis. The results demonstrated that HMJ-30 selectively targeted the ATP-binding site of IGF-1R and inhibited its downstream phosphoinositide 3-kinase/protein kinase B, Ras/mitogen activated protein kinase, and IkappaK/nuclear factor-kappaB signaling pathways in U-2 OS cells. HMJ-30 inhibited U-2 OS cell invasion and migration and downregulated protein levels and activities of matrix metalloproteinase (MMP)-2 and MMP-9. An increase in protein levels of tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2 was also observed. Furthermore, HMJ-30 caused U-2 OS cells to aggregate and form tight clusters, and these cells were flattened, less elongated and displayed cobblestone-like shapes. There was an increase in epithelial markers and a decrease in mesenchymal markers, indicating that the cells underwent the reverse epithelial-mesenchymal transition (EMT) process. Overall, these results demonstrated the potential molecular mechanisms underlying the effects of HMJ-30 on invasiveness and EMT in U-2 OS cells, suggesting that this compound deserves further investigation as a potential anti-osteosarcoma drug. PMID- 29568967 TI - Novel MSH2 splice-site mutation in a young patient with Lynch syndrome. AB - Lynch Syndrome (LS) is associated with germline mutations in one of the mismatch repair (MMR) genes, including MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), MSH6, PMS1 homolog 2, mismatch repair system component (PMS2), MLH3 and MSH3. The mutations identified in MMR genes are point mutations or large rearrangements. The point mutations are certainly pathogenetic whether they determine formation of truncated protein. The mutations that arise in splice sites are classified as 'likely pathogenic' variants. In the present study, a novel splicing mutation was identified, (named c.212-1g>a), in the MSH2 gene. This novel mutation in the consensus splice site of MSH2 exon 2 leads to the loss of the canonical splice site, without skipping in-frame of exon 2; also with the formation of 2 aberrant transcripts, due to the activation of novel splice sites in exon 2. This mutation was identified in a young patient who developed colon cancer at the age of 26 years and their belongs to family that met the 'Revised Amsterdam Criteria'. The present study provided insight into the molecular mechanism determining the pathogenicity of this novel MSH2 mutation and it reaffirms the importance of genetic testing in LS. PMID- 29568968 TI - Screening of potential biomarkers in uterine leiomyomas disease via gene expression profiling analysis. AB - The present study aimed to screen potential biomarkers for uterine leiomyomas disease, particularly target genes associated with the mediator of RNA polymerase II transcription subunit 12 (MED12) mutation. The microarray data of GSE30673, including 10 MED12 wild-type myometrium, 8 MED12 mutation leiomyoma and 2 MED12 wild-type leiomyoma samples, were downloaded from the Gene Expression Omnibus database. Compared with myometrium samples, differently-expressed genes (DEGs) in the MED12 mutation and wild-type leiomyoma samples were identified using the Limma package. The two sets of DEGs obtained were intersected to screen common DEGs. The DEGs in the MED12 mutation and wild-type leiomyoma samples, and common DEGs were defined as group A, B and C. Gene Ontology (GO) and pathway enrichment analyses were performed using the Database for Annotation, Visualization and Integrated Discovery online tool. Based on the Kyoto Encyclopedia of Genes and Genomes database, pathway relation networks were constructed. DEGs in GO terms and pathways were intersected to screen important DEGs. Subsequently, a gene co expression network was constructed and visualized using Cytoscape software. Reverse transcription-quantitative polymerase chain reaction was used to detect the expression levels of important DEGs. A total of 1,258 DEGs in group A were screened, and enriched for extracellular matrix (ECM) organization and ECM receptor interaction. In addition, a total of 1,571 DEGs in group B were enriched for cell adhesion. Furthermore, 391 DEGs were involved in extracellular matrix organization. Pathway relation networks of group A, B and C were constructed with nodes of 48, 39, and 28, respectively. Finally, 135 important DEGs were obtained, including Acyl-CoA synthetase medium-chain family member 3, protein S (alpha) (PROS1) and F11 receptor. A gene co-expression network with 68 nodes was constructed. The expression of caspase 1 (CASP1) and aldehyde dehydrogenase 1 family member A1 (ALDH1A1) was significant higher in SK-UT-1 compared with that in PHM1-31 cells, while the expression of PROS1 was significant lower in SK-UT-1 cells. These results that CASP1, ALDH1A1 and PROS1 may be potential biomarkers for uterine leiomyomas. Furthermore, hematopoietic prostaglandin D synthase and carbonyl reductase 3 (CBR3) may be particular genes associated with the MED12 mutation in this disease. PMID- 29568969 TI - miR-133b-5p contributes to hypoxic preconditioning-mediated cardioprotection by inhibiting the activation of caspase-8 and caspase-3 in cardiomyocytes. AB - In a previous study using a microRNA (miRNA/miR) microarray assay, we demonstrated that miR-133b-5p was upregulated in response to hypoxic preconditioning (HPC). The present study was designed to investigate the role of the miR-133b-5p in HPC-induced cardioprotection and the underlying mechanisms involving caspase-8 and caspase-3 apoptotic signaling. Adult rats were subjected to myocardial ischemia/reperfusion (I/R) injury with or without ischemic preconditioning (IPC), and the level of miR-133b-5p in myocardium was measured. Neonatal rat cardiomyocytes were isolated and subjected to hypoxia/reoxygenation (H/R) injury, with or without HPC. miR-133b-5p antagomir was transfected into the cardiomyocytes to observe whether it could block HPC-induced cardioprotection. Cellular injury was evaluated by detecting cell viability, lactate dehydrogenase (LDH) activity and apoptotic rate. Reverse transcription-quantitative polymerase chain reaction was used to measure the level of miR-133b-5p. The activation of caspase-8 and caspase-3 were measured by western blot analysis to detect the cleaved fragments as well as a colorimetric assay. Following myocardial I/R injury, the expression of miR-133b-5p was decreased in myocardium, while this decrease was restored by IPC. HPC protected neonatal rat cardiomyocytes against H/R injury by increasing cell viability, while reducing LDH release and cell apoptosis. These protective effects were coupled with the upregulation of miR 133b-5p. However, the knockdown of miR-133b-5p in the cardiomyocytes blocked HPC mediated cardioprotection as reflected by the aggravation of cell injury and apoptosis. HPC upregulated miR-133b-5p level was markedly suppressed by the antagomir. In addition, the cleavage and activities of caspase-8 and caspase-3 were inhibited by HPC while reversed by knockdown of miR-133b-5p. Upregulation of miR-133b-5p contributes to HPC-mediated cardioprotection in cardiomyocytes, and the mechanism may be associated with inhibition of caspase-8 and caspase-3 apoptotic signaling.

PMID- 29568970 TI - miR-494-BAG-1 axis is involved in cinobufacini-induced cell proliferation and apoptosis in gastric cancer. AB - Cinobufacini is widely used in the treatment of advanced cancers. It has been previously reported that microRNA (miR)-494 was upregulated in cinobufacini treated gastric cancer cells; however, the detailed role of miR-494 in the anti tumor activity of cinobufacini is unclear. The present study aimed to clarify the function of miR-494 in cinobufacini-induced cell behavior changes. Cell viability and proliferation ability were investigated using a Cell Counting Kit-8 assay. Flow cytometry was performed to investigate the apoptosis rate of gastric cancer (GC) cells. The mRNA expression levels of microRNA (miR)-494 and BCL2 associated athanogene 1 (BAG-1) were investigated using reverse transcription-quantitative polymerase chain reaction, and the protein expression level of BAG-1 was investigated using western blot assays. The results demonstrated that treatment with cinobufacini suppressed proliferation and promoted apoptosis of gastric cancer cells. miR-494 acts as a tumor suppressor gene in gastric cancer. In cinobufacini-treated cells, miR-494 and BAG-1 exhibited opposing expression trends. Furthermore, knockdown of miR-494 in cinobufacini-treated cells upregulated the protein expression level of BAG-1, promoted cell proliferation and inhibited cell apoptosis. In addition, inhibition of BAG-1 using small interfering RNA in cinobufacini-treated cells partially abrogated the effects of miR-494 inhibitor on cell proliferation and apoptosis. Thus, these results suggest that cinobufacini suppresses GC cells proliferation and promotes apoptosis partially through the regulation of miR-494-BAG-1 axis, which may provide a novel insight into the functional mechanism of cinobufacini. PMID- 29568972 TI - Innate lymphoid cells in autoimmunity and chronic inflammatory diseases. AB - Abnormal activation of the innate immune system is a common feature of autoimmune and chronic inflammatory diseases. Since their identification as a separate family of leukocytes, innate lymphoid cells (ILCs) have emerged as important effector cells of the innate immune system. Alterations in ILC function and subtype distribution have been observed in a variety of immune-mediated diseases in humans and evidence from experimental models suggests a subtype specific role of ILCs in the pathophysiology of autoimmune inflammation. In this review, we discuss recent advances in the understanding of ILC biology in autoimmune and chronic inflammatory disorders, including multiple sclerosis, inflammatory bowel diseases, psoriasis, and rheumatic diseases, with a special focus on the potential of ILCs as therapeutic targets for the development of novel treatment strategies in humans. PMID- 29568974 TI - The Cartilage Warp Prevention Suture. AB - BACKGROUND: Costal cartilage graft warping can challenge rhinoplasty surgeons and compromise outcomes. We propose a technique, the "warp control suture," for eliminating cartilage warp and examine outcomes in a pilot group. METHODS: The warp control suture is performed in the following manner: Harvested cartilage is cut to the desired shape and immersed in saline to induce warping. A 4-0 or 5-0 PDS suture, depending the thickness of the cartilage, is passed from convex to concave then concave to convex side several times about 5-6 mm apart, finally tying the suture on the convex side with sufficient tension to straighten the cartilage. First an ex vivo experiment was performed in 10 specimens from 10 different patients. Excess cartilage was sutured and returned to saline for a minimum of 15 min and then assessed for warping compared to cartilage cut in the identical shape also soaked in saline. Then, charts of nine subsequent patients who received the warp control suture on 16 cartilage grafts by the senior author (BG) were retrospectively reviewed. Inclusion of study subjects required at least 6 months of follow-up with standard rhinoplasty photographs. Postoperative complications and evidence of warping were recorded. RESULTS: In the ex vivo experiment, none of the 10 segments demonstrated warping after replacement in saline, whereas all the matching segments demonstrated significant additional warping. Clinically, no postoperative warping was observed in any of the nine patients at least 6 months postoperatively. One case of minor infection was observed in an area away from the graft and treated with antibiotics. No warping or other complications were noted. CONCLUSION: The warp control suture technique presented here effectively straightens warped cartilage graft and prevents additional warping.

PMID- 29568975 TI - Safety of brotizolam in hospitalized patients. AB - PURPOSE: The objective of this study was to evaluate the safety of brotizolam in hospitalized patients. METHODS: A single-center, comparative retrospective cohort analysis of patients hospitalized in internal medicine wards. Patients treated with brotizolam were compared to patients not treated with any benzodiazepines during hospitalization. Primary outcome was any of the following safety events: mechanical ventilation, delirium, and falls. RESULTS: Six hundred patients were included after exclusion in the final analysis; 300 treated with brotizolam (treatment) and 300 not treated with any benzodiazepines (comparator). The brotizolam-treated patients were older with more comorbidities and psychotropic medications. After adjustment using multivariate logistic regression analysis with propensity score, the primary outcomes occurred at significantly higher rates in treated patients than in untreated patients (17 vs. 2 events; OR = 7.33). Any psychotropic medication administered during hospitalization was found by logistic regression to be the main independent risk factor for the studied safety outcomes while age, comorbidities, and the cause of hospitalization were not. CONCLUSIONS: Treatment with brotizolam during hospitalization in internal medicine wards is linked to a higher risk of respiratory deterioration, delirium, and falls. Use of psychotropic medications during hospitalization is the main independent risk factor of safety outcomes. Further research is needed to fully evaluate the risks and benefits of sleep induction medications in hospitals. PMID- 29568973 TI - Neurogenic inflammation and its role in migraine. AB - The etiology of migraine pain involves sensitized meningeal afferents that densely innervate the dural vasculature. These afferents, with their cell bodies located in the trigeminal ganglion, project to the nucleus caudalis, which in turn transmits signals to higher brain centers. Factors such as chronic stress, diet, hormonal fluctuations, or events like cortical spreading depression can generate a state of "sterile inflammation" in the intracranial meninges resulting in the sensitization and activation of trigeminal meningeal nociceptors. This sterile inflammatory phenotype also referred to as neurogenic inflammation is characterized by the release of neuropeptides (such as substance P, calcitonin gene related peptide) from the trigeminal innervation. This release leads to vasodilation, plasma extravasation secondary to capillary leakage, edema, and mast cell degranulation. Although neurogenic inflammation has been observed and extensively studied in peripheral tissues, its role has been primarily investigated in the genesis and maintenance of migraine pain. While some aspects of neurogenic inflammation has been disregarded in the occurrence of migraine pain, targeted analysis of factors have opened up the possibilities of a dialogue between the neurons and immune cells in driving such a sterile neuroinflammatory state in migraine pathophysiology. PMID- 29568976 TI - Pharmacokinetics and -dynamics of intramuscular and intranasal naloxone: an explorative study in healthy volunteers. AB - PURPOSE: This study aimed to develop a model for pharmacodynamic and pharmacokinetic studies of naloxone antagonism under steady-state opioid agonism and to compare a high-concentration/low-volume intranasal naloxone formulation 8 mg/ml to intramuscular 0.8 mg. METHODS: Two-way crossover in 12 healthy volunteers receiving naloxone while receiving remifentanil by a target-controlled infusion for 102 min. The group were subdivided into three different doses of remifentanil. Blood samples for serum naloxone concentrations, pupillometry and heat pain threshold were measured. RESULTS: The relative bioavailability of intranasal to intramuscular naloxone was 0.75. Pupillometry showed difference in antagonism; the effect was significant in the data set as a whole (p < 0.001) and in all three subgroups (p < 0.02-p < 0.001). Heat pain threshold showed no statistical difference. CONCLUSIONS: A target-controlled infusion of remifentanil provides good conditions for studying the pharmacodynamics of naloxone, and pupillometry was a better modality than heat pain threshold. Intranasal naloxone 0.8 mg is inferior for a similar dose intramuscular. Our design may help to bridge the gap between studies in healthy volunteers and the patient population in need of naloxone for opioid overdose. TRIAL REGISTRATION: clinicaltrials.gov : NCT02307721. PMID- 29568977 TI - In silico analysis of endogenous siRNAs associated transposable elements and NATs in Schistosoma japonicum reveals their putative roles during reproductive development. AB - Schistosomiasis is a neglected tropical disease caused by trematode of the genus Schistosoma. Successful reproductive development is critical for the production of eggs, which are responsible for host pathology and disease dissemination. Endogenous small non-coding RNAs play important roles in many biological processes such as protection against foreign pathogens, cell differentiation, and chromosomal stability by regulating target gene expression at the transcriptional and post-transcriptional levels. In this study, we performed in silico analysis of endogenous small non-coding RNAs in different stages, and sex of S. japonicum focusing on endogenous small interfering RNAs (endo-siRNAs) generated from transposable elements (TEs) and natural antisense transcripts (NATs). Both total and unique siRNA populations show 18-30 nt in length, but the predominant size was 20 nt and the leading first base was adenosine. Sense TE-derived endo-siRNAs reads were higher than antisense reads at different relative positions of TEs, whereas no such difference was observed for NAT-derived endo-siRNAs. TE- and NAT derived endo-siRNAs were more enriched in the male compared to female worms, with the higher relative expression in early phase of pairing. Putative targets of endo-siRNAs indicated more of them in males (106 and 66) than in females (6 and 23) for TE- and NAT-derived endo-siRNAs, respectively. Our preliminary study revealed vital role of endo-siRNAs during the reproductive development of S. japonicum and provide clues for putative novel targets to suppress worm reproduction and direction for effective anti-schistosomal drug development. PMID- 29568978 TI - Apoptotic impact on Brugia malayi by sulphonamido-quinoxaline: search for a novel therapeutic rationale. AB - Human lymphatic filariasis although not fatal but poses serious socioeconomic burden due to associated disability. This is reflected by the huge magnitude of the estimated disability-adjusted life years of about 5.09 million. Therefore, following WHO mandate, our earlier studies on antifilarial drug development revealed the significance of apoptosis. Apoptotic impact has been implicated in anticancer rationale of several drugs. In this study, we explored the antifilarial potential of sulphonamido-quinoxaline compounds, shown to be specific inhibitor for c-Met kinase in human cancer cells. Out of studied compounds, Q4, showing favorable drug-likeness and medicinal chemistry properties on bioinformatics platform along with subsequently recorded lowest IC100 value, was considered as a suitable antifilarial candidate. Significant apoptosis due to mitochondrial involvement was recorded in drug-treated parasite unlike untreated control. In spite of homology between human c-Met kinase and Brugia malayi counterpart, comparative docking result of this compound showed more favorable binding parameters with the parasitic target. The wide gap between IC100 and LD50 values further confirmed the therapeutic safety. We propose sulphonamido quinoxaline derivative as a lead candidate for antifilarial drug development. Further study is warranted to authenticate parasitic c-Met kinase as a novel therapeutic target reminiscent of anticancer rationale implicating inhibition of proliferation. PMID- 29568979 TI - Comparison of catheter-over-needle and catheter-through-needle on leakage from the catheter insertion site during continuous femoral nerve block. AB - The aim of this study was to compare the incidences of leakage from the catheter insertion site during continuous femoral nerve block when using the catheter through-needle, Contiplex TouhyTM (CT) and the newly developed catheter-over needle, Contiplex CTM (CC). Forty adult patients who were scheduled to undergo continuous femoral nerve block for pain control following knee surgery were enrolled and were randomly assigned to a CT group or a CC group. After finishing surgery, a catheter for continuous femoral nerve block was placed using ultrasound. A catheter was advanced along the femoral nerve 5-6 cm beyond the needle tip. Then 0.25% levobupivacaine was continuously administered at a rate of 5 ml/h until 9:00 am on postoperative day 1. The incidence of leakage of the local anesthetic from the insertion site in the CT group was significantly higher than that in the CC group. In the CT group, leakage from the catheter insertion site was observed in 11 of 20 patients during the observation period. On the other hand, none of the patients in the CC group showed leakage. Contiplex CTM is more effective than Contiplex TouphyTM for prevention of leakage of local anesthetics from the insertion site during continuous femoral nerve block. PMID- 29568980 TI - Sleep Apnea in Heart Failure. AB - PURPOSE OF REVIEW: In this review, we discuss the current treatment options for sleep-disordered breathing (SDB) in patients with heart failure (HF). We address the role of positive airway pressure (PAP) devices and other emerging therapies. The review includes discussion of recent trials that reported negative consequences for the PAP devices in patients with heart failure. RECENT FINDINGS: Optimal guideline-directed medical therapies of HF and PAP devices have been the mainstay treatments for HF patients with SDB. Recently, randomized controlled trials (RCTs) evaluated the effect of PAP on clinical outcomes in patients with cardiovascular (CV) disease and heart failure and found no benefit in decreasing fatal and non-fatal CV events. The Sleep Apnea Cardiovascular Endpoints (SAVE) trial evaluated continuous positive airway pressure (CPAP) ventilation in patients with CV disease and obstructive sleep apnea (OSA) and did not observe any improvement in CV effect. In patients with HF and central sleep apnea (CSA), adaptive servo-ventilation (ASV) was hypothesized to help HF outcomes, but the Adaptive Servo-Ventilation for Central Sleep Apnea in Systolic Heart Failure (SERVE-HF) trial did not show any mortality benefit. Instead, the trial suggested an increase in all-cause and CV mortality in the treatment arm. currently, studies have not shown the use of PAP therapy to improve any risks of CV outcomes or death in HF patients with sleep apnea, but some associations with improvements in symptoms from OSA have been observed. PMID- 29568983 TI - Model Prediction and Validation of an Order Mechanism Controlling the Spatiotemporal Phenotype of Early Hepatocellular Carcinoma. AB - Recently, hepatocyte-sinusoid alignment (HSA) has been identified as a mechanism that supports the coordination of hepatocytes during liver regeneration to reestablish a functional micro-architecture (Hoehme et al. in Proc Natl Acad Sci 107(23):10371-10376, 2010). HSA means that hepatocytes preferentially align along the closest micro-vessels. Here, we studied whether this mechanism is still active in early hepatocellular tumors. The same agent-based spatiotemporal model that previously correctly predicted HSA in liver regeneration was further developed to simulate scenarios in early tumor development, when individual initiated hepatocytes gain increased proliferation capacity. The model simulations were performed under conditions of realistic liver micro architectures obtained from 3D reconstructions of confocal laser scanning micrographs. Interestingly, the established model predicted that initiated hepatocytes at first arrange in elongated patterns. Only when the tumor progresses to cell numbers of approximately 4000, does it adopt spherical structures. This prediction may have relevant consequences, since elongated tumors may reach critical structures faster, such as larger vessels, compared to a spherical tumor of similar cell number. Interestingly, this model prediction was confirmed by analysis of the spatial organization of initiated hepatocytes in a rat liver tumor initiation study using single doses of 250 mg/kg of the genotoxic carcinogen N-nitrosomorpholine (NNM). Indeed, small clusters of GST-P positive cells induced by NNM were elongated, almost columnar, while larger GDT-P positive foci of approximately the size of liver lobuli adopted spherical shapes. From simulations testing numerous possible mechanisms, only HSA could explain the experimentally observed initial deviation from spherical shape. The present study demonstrates that the architecture of small cell clusters of hepatocytes early after initiation is still controlled by physiological mechanisms. However, this coordinating influence is lost when the tumor grows to approximately 4000 cells, leading to further growth in spherical shape. Our findings stress the potential importance of organ micro-architecture in understanding tumor phenotypes. PMID- 29568982 TI - Intrafollicular thyroid hormone staining in whole-mount zebrafish (Danio rerio) embryos for the detection of thyroid hormone synthesis disruption. AB - Endocrine-disrupting chemicals are known to impact multiple hormonal axes of vertebrates, among which the thyroid system is crucial for multiple developmental and physiological processes. Thus, the present study focused on the semi quantitative visualization of intrafollicular triiodothyronine (T3) and thyroxin (T4) in zebrafish embryos as a potential test system for the detection of disrupted thyroid hormone synthesis. To this end, an antibody-based fluorescence double-staining protocol for whole-mount zebrafish embryos and larvae was adapted to simultaneously detect intrafollicular T3 and T4. During normal development until 10 days post-fertilization (dpf), the number of thyroid follicles increased along the ventral aorta. Concentrations of T4 and T3, measured by fluorescence intensity, increased until 6 dpf, but decreased thereafter. Exposure of zebrafish embryos to propylthiouracil (PTU), a known inhibitor of TH synthesis, resulted in a significant decrease in the number of follicles that stained for T3, whereas a trend for increase in follicles that stained for T4 was observed. In contrast, fluorescence intensity for both thyroid hormones decreased significantly after exposure to PTU. Overall, the zebrafish embryo appears to be suitable for the simultaneous visualization and detection of changing intrafollicular TH contents during normal development and after PTU treatment.

AB - Genome is a complex hierarchical structure, and its spatial organization plays an important role in its function. Chromatin loops and topological domains form the basic structural units of this multiscale organization and are essential to orchestrate complex regulatory networks and transcription mechanisms. They also form higher-order structures such as chromosomal compartments and chromosome territories. Each level of this intrinsic architecture is governed by principles and mechanisms that we only start to understand. In this review, we summarize the current view of the genome architecture on the scales ranging from chromatin loops to the whole genome. We describe cell-to-cell variability, links between genome reorganization and various genomic processes, such as chromosome X inactivation and cell differentiation, and the interplay between different experimental techniques. PMID- 29568987 TI - Furosemide-induced tubular dysfunction responding to prostaglandin synthesis inhibitor therapy in a child with nephrotic syndrome. AB - Furosemide is one of the most common drug used to treat anasarca in childhood nephrotic syndrome. It has minimal side effects on short-term usage, but prolonged use can result in polyuria, hypokalemia and metabolic alkalosis. This pseudo-bartter complication can be treated by discontinuation of the drug with adequate potassium replacement. We report a child who was given furosemide for 20 days elsewhere to treat the edema due to nephrotic syndrome and then presented to us with bartter-like syndrome. Furosemide was discontinued and potassium replacement was initiated. However, the child continued to have polyuria leading to repeated episodes of hypotensive shock. In view of severe symptoms, she was given a short course of oral indomethacin for 6 days, to which she responded. This case highlights the fact that indomethacin can provide symptomatic improvement in furosemide induced pseudo-bartter. PMID- 29568986 TI - Can a workplace leadership intervention reduce job insecurity and improve health? Results from a field study. AB - PURPOSE: To examine the effectiveness of an intervention in the workplace designed to reduce job insecurity among employees affected by organizational change. METHODS: Supervisors were randomly allocated to an intervention (IG) or waiting-list-control group (CG) and the intervention was administered over a period of 3 months, comprising six group sessions. N = 103 supervisors and their team members (mean age 41.80 +/- 9.60 years, 60.19% male) provided data prior to (t0) and 3 months post-intervention (t1) by means of questionnaires and hair samples. Job insecurity (COPSOQ), mental health (HADS) and somatic health (GBB, hair cortisol concentration) were measured. RESULTS: Job insecurity was reduced to a marginally significant degree in the IG compared to the CG at t1 (B = - 5.78, p = .06, CI [- 11.73, 0.17]). Differential effects for supervisors and team members were not found. No effects on health could be observed overall in the IG, but supervisors in the IG reported a significant decrease in exhaustion tendency (B = - 0.92, p = 0.01, CI [- 1.64, - 0.20]) and a non-significant trend towards higher levels of anxiety (B = 2.98, p = 0.10, CI [- 0.57, 6.54]) compared to team members. CONCLUSIONS: This is the first study to provide some evidence for the effectiveness of an intervention that aimed at reducing job insecurity during organizational change. Health-related effects were observed in supervisors but not in team members. Further intervention studies are needed to add to the current knowledge base.

PMID- 29568985 TI - Organ-specific metastasis of breast cancer: molecular and cellular mechanisms underlying lung metastasis. AB - BACKGROUND: Breast cancer (BC) is the most common type of cancer in women and the second cause of cancer-related mortality world-wide. The majority of BC-related deaths is due to metastasis. Bone, lung, brain and liver are the primary target sites of BC metastasis. The clinical implications and mechanisms underlying bone metastasis have been reviewed before. Given the fact that BC lung metastasis (BCLM) usually produces symptoms only after the lungs have been vastly occupied with metastatic tumor masses, it is of paramount importance for diagnostic and prognostic, as well as therapeutic purposes to comprehend the molecular and cellular mechanisms underlying BCLM. Here, we review current insights into the organ-specificity of BC metastasis, including the role of cancer stem cells in triggering BC spread, the traveling of tumor cells in the blood stream and their migration across endothelial barriers, their adaptation to the lung microenvironment and the initiation of metastatic colonization within the lung. CONCLUSIONS: Detailed understanding of the mechanisms underlying BCLM will shed a new light on the identification of novel molecular targets to impede daunting pulmonary metastases in patients with breast cancer.

AB - To characterize the clinical features, associated disorders, and treatment of necrobiotic xanthogranuloma (NXG), a rare non-Langerhans cell histiocytosis, we conducted a retrospective review of pathologically confirmed NXG at Mayo Clinic Arizona from 1987 to June 2017. Data on clinical findings, laboratory findings, associated disorders, therapy, and response to therapy were extracted. Nineteen patients were identified. Mean age was 54 years (range, 17-84) with equal gender distribution. Median follow-up was 5.5 years (range, 1-18). Most patients had a detectable monoclonal protein (84%), and IgG kappa constituted 58%. The most common cutaneous lesions involved the periorbital region (53%). The majority of patients had extracutaneous manifestations, most commonly affecting the liver (32%) and the sinuses (21%). Hematologic malignancies were diagnosed in 26% of patients and included Hodgkin lymphoma, chronic lymphocytic leukemia (CLL), smoldering myeloma, and multiple myeloma. The most common treatment was chlorambucil with or without systemic corticosteroids. Response was seen in most patients (95%), and most patients received 1-3 lines of therapy (74%). NXG is a reactive histiocytic disorder that commonly involves multiple organ systems and requires a high degree of clinical suspicion for accurate diagnosis. Treatment decisions should be based on coexisting conditions and pattern of disease involvement. PMID- 29568991 TI - Large granular lymphocytic leukemia-associated peripheral neuropathy.

PMID- 29568993 TI - Quantitative T-cell repertoire analysis of peripheral blood mononuclear cells from lung cancer patients following long-term cancer peptide vaccination. AB - Therapeutic cancer peptide vaccination is an immunotherapy designed to elicit cytotoxic T-lymphocyte (CTL) responses in patients. A number of therapeutic vaccination trials have been performed, nevertheless there are only a few reports that have analyzed the T-cell receptors (TCRs) expressed on tumor antigen specific CTLs. Here, we use next-generation sequencing (NGS) to analyze TCRs of vaccine-induced CTL clones and the TCR repertoire of bulk T cells in peripheral blood mononuclear cells (PBMCs) from two lung cancer patients over the course of long-term vaccine therapy. In both patients, vaccination with two epitope peptides derived from cancer/testis antigens (upregulated lung cancer 10 (URLC10) and cell division associated 1 (CDCA1)) induced specific CTLs expressing various TCRs. All URLC10-specific CTL clones tested showed Ca2+ influx, IFN-gamma production, and cytotoxicity when co-cultured with URLC10-pulsed tumor cells. Moreover, in CTL clones that were not stained with the URLC10/MHC-multimer, the CD3 zeta chain was not phosphorylated. NGS of the TCR repertoire of bulk PBMCs demonstrated that the frequency of vaccine peptide-specific CTL clones was near the minimum detectable threshold level. These results demonstrate that vaccination induces antigen-specific CTLs expressing various TCRs at different time points in cancer patients, and that some CTL clones are maintained in PBMCs during long-term treatment, including some with TCRs that do not bind peptide/MHC multimer.

AB - Haploidentical hematopoietic stem cell transplant (haplo-HSCT) is an upfront and effective therapy for hematology patients, but it usually has many complications, such as neurological complications. As one of the neurological complications following haplo-HSCT, immune-mediated demyelinating diseases of the central nervous system (CNS) seriously affect a patient's quality of life. However, the incidence, risk factors, and pathogenesis of CNS demyelination are not very well understood. Thirty of the 1526 patients (1.96%) suffered from CNS demyelination. In univariate analysis, we found that blood-brain barrier (BBB) permeability and the CSF IgG synthesis index (IgG-Syn) were related to the occurrence of CNS demyelination (p < 0.05). In a multivariate analysis, the IgG-Syn (OR = 1.017, 95% CI 1.003-1.031, p = 0.019) and CSF anti-myelin oligodendrocyte glycoprotein antibody (MOG.Ab) (OR = 12.059, 95% CI 1.141-127.458, p = 0.038) were independently associated with the onset of CNS demyelination. We also studied the possible pathogenesis of CNS demyelination. Immune reconstitution (the cell proportions of CD19+ B cells, CD3+ T cells, and CD4+ T cells); the counts of leucocytes, lymphocytes, monocytes, and platelets; and the levels of immunoglobulins A, G, and M 30, 60, and 90 days after HSCT showed no significant differences between CNS demyelination and no demyelination (p > 0.05). The probabilities of overall survival showed no significant differences between patients with and without demyelination (p > 0.05). Only four deaths in 30 patients, but bringing projected survival to less than 20%.We imply that IgG-Syn and CSF MOG. Ab may be associated with the onset of CNS demyelination during 2 weeks of neurological symptoms in patients with brain or spinal cord MRI abnormality. Immune reconstitution may not be the pathogenesis of CNS demyelination. PMID- 29568994 TI - Preliminary evidence of nanoparticle occurrence in water from different regions of Delhi (India). AB - The objective of this study was to obtain preliminary evidence of metal-based nanoparticle (NP) occurrence in Delhi (India). Six sampling locations (inlets and outlets of two different municipal wastewater treatment plants (WWTPs), groundwater, and river water) were collected in three independent sampling events. Microscopic analysis (TEM) found majority (40%) of the particles ranged between 150 and 200 nm followed by particles of size 100-150 nm (22%) at the inlet of WWTP, while at outlet, 90% of the particles were < 100 nm. Compared with the outlet of the WWTPs, particles at the inlet were found to be greater than 40%. Intensity-based particle size distribution (PSD) revealed particle size at influent in the range of 210 nm, while at effluent, particle size for both WWTPs ranged < 100 nm. Particles of size between 100 and 200 nm were found to get removed from both the treatment plants and thus making it evident that NP gets settled or adsorbed in sludge. Spectral analysis (EDX) further confirmed the presence of metals such as Al, As, Ag, Mn, Fe, Ti, and Zn at different weight percentages. Overall, findings of this study confirmed the presence of metal based engineered NPs (ENPs) from anthropogenic sources and it cannot also be ruled out the possible formation of NPs within the wastewater from natural minerals. Moreover, to solve definitive clues for ascertaining the sources of NPs in complex samples, more sophisticated research techniques, such as inductively coupled plasma-mass spectrometry (ICP-MS) in combination with field flow fractionation, single-particle ICP-MS, and radio-labeling in combination or in single should be considered. PMID- 29568995 TI - [Chronic prurigo]. AB - Chronic prurigo is a disease characterized by the presence of chronic pruritus and singular or multiple usually hyperkeratotic symmetrically distributed itchy papules, nodules, and/or plaques. This condition is difficult to treat and leads to a substantial impairment of the quality of life. It may originate from dermatological, systemic, neurological, psychiatric/psychosomatic, multifactorial or unknown conditions causing itch, which lead to prolonged scratching behavior and sensitization mechanisms and ultimately to the development of pruriginous lesions. Thorough diagnostic efforts, including a detailed clinical history and physical examination, as well as targeted complementary examinations should be initiated as soon as possible. The German guideline recommends topical steroids and phototherapy as first-choice options. Pimecrolimus and capsaicin (topical), as well as antihistamines, anticonvulsants, and immunosuppressive drugs (systemic) should be considered as valid alternatives. PMID- 29568996 TI - [Side effects of biologic therapies in psoriasis]. AB - BACKGROUND: The introduction of biologics has revolutionized the treatment of moderate to severe plaque psoriasis. Due to the continuous expansion of biological therapies for psoriasis, it is particularly important to acknowledge efficacy and safety of the compounds not only in clinical trials but also in long term registry-based observational studies. AIM: Typical side effects and significant risks of antipsoriatic biologic therapies considering psoriatic control groups are presented. MATERIALS AND METHODS: A selective literature search was conducted in PubMed and long-term safety studies of the psoriasis registries PsoBest, PSOLAR and BADBIR were evaluated. RESULTS AND DISCUSSION: To assess the long-term safety of biologics, the evaluation of the course of large patient cohorts in long-term registries is of particular medical importance. Newer biologic drugs seem to exhibit a better safety profile than older ones. PMID- 29568997 TI - [Severe skin reactions due to new medications]. AB - Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and a specific form of hypersensitivity syndrome which is nowadays called "drug reaction with eosinophilia and systemic symptoms" (DRESS) are severe, mainly drug-induced skin reactions. Whereas SJS/TEN is considered one reaction entity of different severity, DRESS has to be distinguished from SJS/TEN but also from other severe exanthems due to multiorgan involvement. Although SJS/TEN is generally referred to as drug reaction, in total only about three quarters of the cases are actually caused by drugs. After the clinical diagnosis is made, identification of the potential inducing factor is most important. In case medications are considered as causal, their withdrawal plays a key role in management. In order to identify and withdraw the inducing agent, a detailed and thorough medication history must be obtained. Agents identified or confirmed as inducers of SJS/TEN by pharmacoepidemiological studies are allopurinol, antibacterial sulfonamides, various antiepileptics, nevirapine and nonsteroidal anti-inflammatory drugs of the oxicam-type. Among drugs inducing DRESS are also various antiepileptics, but in addition allopurinol, sulfonamides and minocycline. Some cases of SJS/TEN and DRESS associated with the use of new medication, including targeted therapies and biologicals, have been observed.

AB - Rigorous HIV-related data for the homeless population in Jamaica is limited. A cross-sectional survey using a venue-based sampling approach was conducted in 2015 to derive HIV prevalence and associated risk factors. Three hundred twenty three homeless persons from the parishes of St. James, St. Ann, Kingston, and St. Andrew (the main urban centers) participated. HIV prevalence was 13.8%, with a difference in gender (males 11.6%, females 26.7%, P = .007). Sex work, multiple partnerships, incarceration, non-injecting drug use, and female rape were common among the participants. Long-term, multilayered, HIV-specific, female-focused interventions are required for the population, along with additional female centric research. PMID- 29569001 TI - The alcohol-intoxicated trauma patient: impact on imaging and radiation exposure. AB - INTRODUCTION: The purpose of this study was to investigate the effects of alcohol intoxication in trauma patients in regard to its impact on application of computed tomography (CT) and associated radiation exposure. METHODS: We conducted a retrospective study from a continuous patient cohort. INCLUSION CRITERIA: admission to the emergency room of an urban Level 1 trauma center with trauma team activation during a 12-month period (Jan 1st-Dec 31st 2012). Patients with incomplete data, age <= 12 years and with neurological diseases were excluded. Demographics, mechanisms, severity and patterns of injury (Abbreviated Injury Scale, Injury Severity Score, Glasgow Coma Scale), blood alcohol concentration (BAC, in permille, 0/00), imaging studies (head/whole body CT), radiation exposure, and hospital length of stay, surgical procedures and mortality were evaluated with SPSS statistics (Version 25, IBM Inc., Armonk, New York). RESULTS: A positive BAC (mean 1.80 +/- 0.767) was reported in 19.2% (n = 41/214) of the cohort. Alcohol intoxication was associated with higher utilization of head CT (65.9 vs. 46.8%, p = 0.017) and radiation exposure (231.75 vs. 151.25 mAS, p = 0.045; dose-length product, 583.03 vs. 391.04, p = 0.006). In general, the presence of alcohol was associated with over-triage (p = 0.001), despite minor injury severity (ISS < 9) and a comparable rate of head injuries (p = 0.275). Head injury (AIS >= 3) and positive BAC (OR 2.34, 95% CI 1.096-5.001) were identified as strongest independent predictors for head CT. CONCLUSION: Alcohol intoxication is a common finding in trauma patients, and the rate of moderate and serious head injuries seems to be comparable to a more severely injured control group. Furthermore, head CT utilization in intoxicated patients is associated with significant radiation exposure, despite poor image quality, due to motion artifacts (27%). Future strategies are required to exclude head injuries safely, while reducing the rate of head CT and associated radiation exposure in intoxicated patients. PMID- 29569000 TI - The Influence of Internalized Stigma on the Efficacy of an HIV Prevention and Relationship Education Program for Young Male Couples. AB - Young MSM are at increased risk for HIV, especially in the context of serious relationships, but there is a lack of couples-based HIV prevention for this population. The 2GETHER intervention-an HIV prevention and relationship education program for young male couples-demonstrated promising effects in a pilot trial. However, there is evidence that internalized stigma (IS) can influence treatment outcomes among MSM. The current study examined the influence of IS on the efficacy of the 2GETHER intervention among 57 young male couples. The intervention led to decreases in percentage of condomless anal sex partners and increases in subjective norms regarding HIV prevention for those with low/average IS, but not high IS. The intervention also led to increases in motivation to get tested with one's partner and decreases in alcohol consumption for those with high IS, but not low/average IS. In contrast, IS did not moderate intervention effects on other motivational constructs, dyadic adjustment, or alcohol problems. In sum, IS influences the extent to which young male couples benefit from HIV prevention and relationship education depending on the outcome. Research is needed to understand how IS influences treatment outcomes. PMID- 29569002 TI - Mast Cells and Serotonin Synthesis Modulate Chagas Disease in the Colon: Clinical and Experimental Evidence. AB - BACKGROUND: Trypanosoma cruzi (T. cruzi) infects millions of Latin Americans each year and can induce chagasic megacolon. Little is known about how serotonin (5 HT) modulates this condition. Aim We investigated whether 5-HT synthesis alters T. cruzi infection in the colon. MATERIALS AND METHODS: Forty-eight paraffin embedded samples from normal colon and chagasic megacolon were histopathologically analyzed (173/2009). Tryptophan hydroxylase 1 (Tph1) knockout (KO) mice and c-KitW-sh mice underwent T. cruzi infection together with their wild-type counterparts. Also, mice underwent different drug treatments (16.1.1064.60.3). RESULTS: In both humans and experimental mouse models, the serotonergic system was activated by T. cruzi infection (p < 0.05). While treating Tph1KO mice with 5-HT did not significantly increase parasitemia in the colon (p > 0.05), rescuing its synthesis promoted trypanosomiasis (p < 0.01). T. cruzi-related 5-HT release (p < 0.05) seemed not only to increase inflammatory signaling, but also to enlarge the pericryptal macrophage and mast cell populations (p < 0.01). Knocking out mast cells reduced trypanosomiasis (p < 0.01), although it did not further alter the neuroendocrine cell number and Tph1 expression (p > 0.05). Further experimentation revealed that pharmacologically inhibiting mast cell activity reduced colonic infection (p < 0.01). A similar finding was achieved when 5-HT synthesis was blocked in c-KitW-sh mice (p > 0.05). However, inhibiting mast cell activity in Tph1KO mice increased colonic trypanosomiasis (p < 0.01). CONCLUSION: We show that mast cells may modulate the T. cruzi-related increase of 5-HT synthesis in the intestinal colon. PMID- 29569003 TI - Tacrolimus and Mycophenolate Mofetil as Second-Line Therapies for Pediatric Patients with Autoimmune Hepatitis. AB - BACKGROUND: We studied the efficacy and safety of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy in pediatric patients with autoimmune hepatitis (AIH) who were intolerant or non-responders to standard therapy (corticosteroid and azathioprine). PATIENTS AND METHODS: We performed a retrospective study of data from 13 centers in Europe, USA, and Canada. Thirty-eight patients (< 18 years old) who received second-line therapy (18 MMF and 20 tacrolimus), for a median of 72 months (range 8-182) were evaluated. Patients were categorized into two groups: Group 1 (n = 17) were intolerant to corticosteroid or azathioprine, and group 2 (n = 21) were non-responders to standard therapy. RESULTS: Overall complete response rates were similar in patients treated with MMF and tacrolimus (55.6 vs. 65%, p = 0.552). In group 1, MMF and tacrolimus maintained a biochemical remission in 88.9 and 87.5% of patients, respectively (p = 0.929). More patients in group 2 given tacrolimus compared to MMF had a complete response, but the difference was not statistically significant (50.0 vs. 22.2%, p = 0.195). Biochemical remission was achieved in 71.1% (27/38) of patients by tacrolimus and/or MMF. Decompensated cirrhosis was more commonly seen in MMF and/or tacrolimus non-responders than in responders (45.5 vs. 7.4%, p = 0.006). Five patients who received second-line therapy (2 MMF and 3 tacrolimus) developed side effects that led to therapy withdrawal. CONCLUSIONS: Long-term therapy with MMF or tacrolimus was generally well tolerated by pediatric patients with AIH. Both MMF and tacrolimus had excellent efficacy in patients intolerant to corticosteroid or azathioprine. Tacrolimus might be more effective than MMF in patients failing previous therapy. PMID- 29569004 TI - [Manifestation of eosinophilic granulomatosis with polyangiitis in the head and neck area over time taking systemic disease activity into consideration]. AB - BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare granulomatous vasculitis of the small and medium sized blood vessels of unknown etiology. A regular involvement of the head and neck area is known. Since it is not yet known whether the inflammatory processes in the head and neck area are parallel to the systemic disease activity, the course of systemic and local disease activity was investigated in a comparative study. MATERIAL AND METHODS: Between 1990 and 2010 the disease progression of 25 patients with a total of 90 consultations and an average observation period of 7.02 years was recorded. The anamnesis, clinical observation and testing were performed in order to describe ear nose and throat (ENT) manifestations. Moreover, systemic data, such as the Birmingham Vasculitis Activity Score (BVAS), the Vasculitis Damage Index (VDI) and the serological parameters C-reactive protein (CRP), eosinophilic cationic protein (ECP) and absolute eosinophil count (EOS) were collected. In order to define the activity in the head and neck area the existing manifestations were summarized and statistically compared to the systemic data using Spearman's rank correlation coefficient. RESULTS: Overall the statistical analysis showed a very weak correlation between the disease activity in the ENT area and systemic disease activity, which is not considered as significant. Comparing activity in the nose region to systemic activity, significant values were found in 22.9% of all consultations. Comparing activity in the ear region to systemic activity, 11.8% of all consultations showed significant values. CONCLUSION: The results indicate that the disease activity in the head and neck area is independent of the systemic activity. Moreover, they point out a potential independent autoimmune inflammatory process in the mentioned regions; therefore, treatment should include long-term follow-up and an interdisciplinary management. PMID- 29569005 TI - Impact of Post-Discharge Disposition on Risk and Causes of Readmission Following Liver and Pancreas Surgery. AB - BACKGROUND: The relationship between the post-discharge settings and the risk of readmission has not been well examined. We sought to identify the association between discharge destinations and readmission rates after liver and pancreas surgery. METHODS: The 2013-2015 Medicare-Provider Analysis and Review (MEDPAR) database was reviewed to identify liver and pancreas surgical patients. Patients were subdivided into three groups based on discharge destination: home/self-care (HSC), home with home health assistance (HHA), and skilled nursing facility (SNF). The association between post-acute settings, readmission rates, and readmission causes was assessed. RESULTS: Among 15,141 liver or pancreas surgical patients, 60% (n = 9046) were HSC, 26.9% (n = 4071) were HHA, and 13.4% (n = 2024) were SNF. Older, female patients and patients with >= 2 comorbidities, >= 2 previous admissions, an emergent index admission, an index complication, and >= 5 day length of stay were more likely to be discharged to HHA or SNF compared to HSC (all P < 0.001). Compared to HSC, HHA and SNF patients had a 34 and a 67% higher likelihood of 30-day readmission, respectively. The HHA and SNF settings were also associated with a 33 and a 69% higher risk of 90-day readmission. There was no association between discharge destination and readmission causes. CONCLUSION: Among liver and pancreas surgical patients, HHA and SNF patients had a higher risk of readmission within 30 and 90 days. There was no difference in readmission causes and discharge settings. The association between discharge setting and the higher risk of readmission should be further evaluated as the healthcare system seeks to reduce readmission rates after surgery. PMID- 29569006 TI - Contemporary Management of Sigmoid Volvulus. AB - BACKGROUND: Sigmoid volvulus is an uncommon cause of bowel obstruction that is historically associated with high morbidity and mortality. The objective of this study was to evaluate contemporary management of sigmoid volvulus and the safety of primary anastomosis in patients with sigmoid volvulus. METHODS: The National Surgical Quality Improvement Project from 2012 to 2015 was queried for patients with colonic volvulus who underwent left-sided colonic resection. A propensity score-matched analysis was performed to compare patients with sigmoid volvulus undergoing colectomy with primary anastomosis without proximal diversion to colectomy with end colostomy. RESULTS: Two thousand five hundred thirty-eight patients with sigmoid volvulus were included for analysis. Patients had a median age of 68 years (interquartile range, 55-80) and 79% were fully independent preoperatively. Fifty-one percent of operations were performed emergently. One thousand eight hundred thirteen (71%) patients underwent colectomy with anastomosis, 240 (10%) colectomy with anastomosis and proximal diversion, and 485 (19%) colectomy with end colostomy. Overall, 30-day mortality and morbidity were 5 and 40%, respectively. After propensity score matching, mortality, overall morbidity, and serious morbidity were similar between groups. CONCLUSIONS: Sigmoid volvulus occurs in elderly and debilitated patients with significant morbidity, mortality, and lifestyle implications. In selected patients, anastomosis without proximal diversion in patients with sigmoid volvulus results in similar outcomes to colectomy with end colostomy. PMID- 29569007 TI - Associations between fruit and vegetables intake and abnormal glucose tolerance among women with prior gestational diabetes mellitus. AB - PURPOSE: Women with prior gestational diabetes mellitus (GDM) are at higher risk of type 2 diabetes (T2D). The aim of this study was to investigate the association between fruit and vegetables (FV) intake and abnormal glucose tolerance (AGT) among women with prior GDM. METHODS: A total of 281 women with prior GDM have been recruited a mean of 6 years after their pregnancy in this cohort study. FV intake was obtained with a validated food frequency questionnaire (FFQ). Anthropometric and glycemic components were measured during their clinical visit and women were stratified according to normal glucose tolerance (NGT) or AGT. RESULTS: A cross-sectional analysis showed that a total of 155 women had NGT and 126 AGT. Women with AGT had significantly lower FV (6.5 +/- 0.2) and vegetables servings (3.9 +/- 0.2) and tended to have lower fruit servings (2.6 +/- 0.2) than women with NGT (7.4 +/- 0.2, 4.5 +/- 0.2 and 3.0 +/- 0.1, respectively) (p = 0.001, p = 0.04 and p = 0.10, respectively, adjusted for age and BMI). FV intake, per one serving increase, was associated with a reduced likelihood of having AGT [OR = 0.88 (0.81-0.97) after adjustment for age and BMI]. Vegetables or fruit intake tended to be associated with a reduced likelihood of having AGT [OR = 0.88 (0.78-1.00) and OR = 0.88 (0.76-1.02), respectively, after adjustment for age and BMI]. CONCLUSIONS: Higher intake of FV may be associated with a lower likelihood of AGT among women with prior GDM. Further studies are needed to confirm these results in this high-risk population. PMID- 29569008 TI - Dopamine receptors in the rat entopeduncular nucleus. AB - Dopamine is critical for the normal functioning of the basal ganglia, modulating both input and output nuclei of this system. The distribution and function of each of the five dopamine receptor subtypes have been studied extensively in the striatum. However, the role of extrastriatal dopamine receptors in basal ganglia information processing is less clear. Here, we studied the anatomical distribution of dopamine receptors in one of the output nuclei of the rodent basal ganglia, the entopeduncular nucleus (EP). The presence of all dopamine receptor subtypes was verified in the EP using immunostaining. We detected co localization of dopamine receptors with VGAT, which suggests presynaptic expression on GABAergic terminals. D1R and D2R were strongly colocalized with VGAT, whereas DR3-5 showed only sparse co-localization. We further labeled striatal or pallidal neurons with GFP and showed that only D1 receptors were co localized with striatal terminals, while only D2R and D3R were co-localized with pallidal terminals. Dopamine receptors were also strongly co-localized with MAP2, indicating postsynaptic expression. Overall, these findings suggest that the dopaminergic system modulates activity in the EP both directly via postsynaptic receptors, and indirectly via GABAergic synapses stemming from the direct and indirect pathways. PMID- 29569010 TI - Posterior Circulation Occlusions May Be Associated with Distal Emboli During Thrombectomy : Factors for Distal Embolization and a Review of the Literature. AB - BACKGROUND: Distal embolization or movement of the thrombus to previously uninvolved vasculature are feared complications during stroke thrombectomy. We looked at associated factors in a consecutive series of patients who underwent thrombectomy with the same endovascular device. METHODS: We included all patients with acute ischemic stroke in the anterior or posterior circulation, who underwent thrombectomy with the same thrombectomy device for acute stroke from 2013 to 2016. Distal embolization was defined as any movement of the thrombus into a previously uninvolved portion of the cerebral vasculature or the presence of thrombotic material further downstream in the affected vessel, which occurred after the initial angiogram. We studied patient-related as well as technical factors to determine their association with distal emboli. RESULTS: In this study 167 consecutive acute stroke patients treated with the emboTrap(r) device (Cerenovus, Irvine, CA, USA) were included with a median National Institutes of Health Stroke Scale (NIHSS) of 15 (range 2-30) and mean age of 67 years (SD 13.1 years). Of the patients in our cohort 20 (11.9%) experienced distal emboli, with 2.3% into a new territory and 9.6% into a territory distal to the primary occlusion. On univariate analysis, age, intravenous tissue plasminogen activator (tPA), posterior circulation occlusions, and general anesthesia were associated with distal emboli. On multivariate analysis, only posterior circulation occlusions (odds ratio OR 4.506 95% confidence interval CI 1.483-13.692, p = 0.008) were significantly associated with distal emboli. Distal embolization was not significantly associated with worse functional outcomes at 3 months, increased mortality or increased bleeding risk. CONCLUSION: Posterior circulation occlusions were significantly associated with distal emboli during thrombectomy, possibly due to the lack of flow arrest during such procedures. New techniques and devices should be developed to protect against embolic complications during posterior circulation stroke thrombectomy. PMID- 29569009 TI - Paraventricular hypothalamic and amygdalar CRF neurons synapse in the external globus pallidus. AB - Stress evokes directed movement to escape or hide from potential danger. Corticotropin-releasing factor (CRF) neurons are highly activated by stress; however, it remains unclear how this activity participates in stress-evoked movement. The external globus pallidus (GPe) expresses high levels of the primary receptor for CRF, CRFR1, suggesting the GPe may serve as an entry point for stress-relevant information to reach basal ganglia circuits, which ultimately gate motor output. Indeed, projections from CRF neurons are present within the GPe, making direct contact with CRFR1-positive neurons. CRFR1 expression is heterogenous in the GPe; prototypic GPe neurons selectively express CRFR1, while arkypallidal neurons do not. Moreover, CRFR1-positive GPe neurons are excited by CRF via activation of CRFR1, while nearby CRFR1-negative neurons do not respond to CRF. Using monosynaptic rabies viral tracing techniques, we show that CRF neurons in the stress-activated paraventricular nucleus of the hypothalamus (PVN), central nucleus of the amygdala (CeA), and bed nucleus of the stria terminalis (BST) make synaptic connections with CRFR1-positive neurons in the GPe an unprecedented circuit connecting the limbic system with the basal ganglia. CRF neurons also make synapses on Npas1 neurons, although the majority of Npas1 neurons are arkypallidal and do not express CRFR1. Interestingly, prototypic and arkypallidal neurons receive different patterns of innervation from CRF-rich nuclei. Hypothalamic CRF neurons preferentially target prototypic neurons, while amygdalar CRF neurons preferentially target arkypallidal neurons, suggesting that these two inputs to the GPe may have different impacts on GPe output. Together, these data describe a novel neural circuit by which stress-relevant information carried by the limbic system signals in the GPe via CRF to influence motor output. PMID- 29569013 TI - Prevention of Contrast and Radiation Injury During Coronary Angiography and Percutaneous Coronary Intervention. AB - PURPOSE OF REVIEW: In this review, we provide a summary of the recently published literature on various methods of preventing contrast-induced acute kidney injury (CI-AKI) and radiation-related injuries associated with cardiac catheterization and percutaneous coronary intervention (PCI). RECENT FINDINGS: The overall reported incidence of CI-AKI is declining, primarily due to adaptation of a standardized definition for CI-AKI as well as implementation of pre-procedural protocols to prevent or decrease the risk of CI-AKI. The implementation of increasing awareness and establishing radiation protection culture has been shown to be effective measures in reducing radiation exposure. Coronary angiography and PCI are valuable diagnostic and therapeutic tools in cardiovascular medicine. Accurate imaging of the coronary arteries in cardiac catheterization is dependent on the use of intravascular injection of iodinated contrast media and fluoroscopic imaging. Patients undergoing diagnostic and interventional cardiac catheterization may be exposed to a substantial amount of contrast media and ionizing radiation. Administration of contrast media is correlated with increased risk of CI-AKI, and exposure to radiation is known to be associated with a spectrum of acute and chronic tissue injuries. PMID- 29569014 TI - Do country-specific preference weights matter in the choice of mapping algorithms? The case of mapping the Diabetes-39 onto eight country-specific EQ-5D 5L value sets. AB - PURPOSE: To develop mapping algorithms that transform Diabetes-39 (D-39) scores onto EQ-5D-5L utility values for each of eight recently published country specific EQ-5D-5L value sets, and to compare mapping functions across the EQ-5D 5L value sets. METHODS: Data include 924 individuals with self-reported diabetes from six countries. The D-39 dimensions, age and gender were used as potential predictors for EQ-5D-5L utilities, which were scored using value sets from eight countries (England, Netherland, Spain, Canada, Uruguay, China, Japan and Korea). Ordinary least squares, generalised linear model, beta binomial regression, fractional regression, MM estimation and censored least absolute deviation were used to estimate the mapping algorithms. The optimal algorithm for each country specific value set was primarily selected based on normalised root mean square error (NRMSE), normalised mean absolute error (NMAE) and adjusted-r2. Cross validation with fivefold approach was conducted to test the generalizability of each model. RESULTS: The fractional regression model with loglog as a link function consistently performed best in all country-specific value sets. For instance, the NRMSE (0.1282) and NMAE (0.0914) were the lowest, while adjusted-r2 was the highest (52.5%) when the English value set was considered. Among D-39 dimensions, the energy and mobility was the only one that was consistently significant for all models. CONCLUSIONS: The D-39 can be mapped onto the EQ-5D-5L utilities with good predictive accuracy. The fractional regression model, which is appropriate for handling bounded outcomes, outperformed other candidate methods in all country-specific value sets. However, the regression coefficients differed reflecting preference heterogeneity across countries.

AB - OBJECTIVE: Classic theory test has been used to develop and validate the 25-item Resilience Scale Specific to Cancer (RS-SC) in Chinese patients with cancer. This study was designed to provide additional information about the discriminative value of the individual items tested with an item response theory analysis. METHODS: A two-parameter graded response model was performed to examine whether any of the items of the RS-SC exhibited problems with the ordering and steps of thresholds, as well as the ability of items to discriminate patients with different resilience levels using item characteristic curves. RESULTS: A sample of 214 Chinese patients with cancer diagnosis was analyzed. The established three dimension structure of the RS-SC was confirmed. Several items showed problematic thresholds or discrimination ability and require further revision. CONCLUSIONS: Some problematic items should be refined and a short-form of RS-SC maybe feasible in clinical settings in order to reduce burden on patients. However, the generalizability of these findings warrants further investigations. PMID- 29569016 TI - PROMIS(r)-29 v2.0 profile physical and mental health summary scores. AB - PURPOSE: The PROMIS-29 v2.0 profile assesses pain intensity using a single 0-10 numeric rating item and seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance) using four items per domain. This paper describes the development of physical and mental health summary scores for the PROMIS-29 v2.0. METHOD: We conducted factor analyses of PROMIS-29 scales on data collected from two internet panels (n = 3000 and 2000). RESULTS: Confirmatory factor analyses provided support for a physical health factor defined by physical function, pain (interference and intensity), and ability to participate in social roles and activities, and a mental health factor defined primarily by emotional distress (anxiety and depressive symptoms). Reliabilities for these two summary scores were 0.98 (physical health) and 0.97 (mental health). Correlations of the PROMIS-29 v2.0 physical and mental health summary scores with chronic conditions and other health-related quality of life measures were consistent with a priori hypotheses. CONCLUSIONS: This study develops and provides preliminary evidence supporting the reliability and validity of PROMIS 29 v2.0 physical and mental health summary scores that can be used in future studies to assess impacts of health care interventions and track changes in health over time. Further evaluation of these and alternative summary measures is recommended. PMID- 29569017 TI - A review of preference-based measures for the assessment of quality of life in children and adolescents with cerebral palsy. AB - PURPOSE: To examine the psychometric properties and suitability for use within the context of cerebral palsy research in children and adolescents of generic preference-based outcome measures (PROMs). METHODS: Nine electronic databases were searched in this systematic review. The consensus-based standards for the selection of health measurement instruments (COSMIN) checklist were used to measure the psychometric properties of the PROMs. A meta-analysis was used to pool correlation coefficients for convergent validity using the Schmidt-Hunter method. Heterogeneity was assessed using the I-squared statistic (I2). RESULTS: Four preference-based PROMs were identified from eight studies: Health Utilities Index-Mark 2 and 3 (HUI-2 and HUI-3, respectively), the Assessment Quality of Life-4 dimension (AQoL-4D) and the EuroQol-5 dimension 3 level (EQ-5D-3L). Only the HUI system was primarily developed for application with children/adolescents though health-state values for scoring the PROM were elicited from adults. The HUI-3 covered the most relevant constructs though it excludes important modules of health-related quality of life (HRQOL) such as activity limitations and participation restrictions. In terms of psychometric properties, evidence was presented for only five of COSMIN measurement properties: reliability (HUI3), measurement error (HUI-3), content validity (HUI-2 and HUI-3), Hypotheses testing (HUI-3 and AQoL-4D) and criterion validity (HUI-3). No papers reported on internal consistency, structural validity, cross-cultural validity or responsiveness of the preference-based measures in children and adolescents with cerebral palsy. CONCLUSIONS: This review highlights the dearth in studies using preference-based PROMs to measure HRQOL associated with cerebral palsy in children and adolescents. The HUI-3 demonstrated the strongest psychometric properties, though it does not cover all dimensions relevant to this population. PMID- 29569018 TI - Breast cancer survival, survival disparities, and guideline-based treatment. AB - PURPOSE: The role of appropriate therapy in breast cancer survival and survival disparities by race/ethnicity has not been fully elucidated. We investigated whether lack of guideline-recommended therapy contributed to survival differences overall and among Hispanics relative to non-Hispanic white (NHW) women in a case cohort study. METHODS: The study included a 15% random sample of female invasive breast cancer patients diagnosed from 1997 to 2009 in 6 New Mexico counties and all deaths due to breast cancer-related causes. Information was obtained from comprehensive medical chart reviews. National Comprehensive Cancer Network (NCCN(r)) guideline-recommended treatment was assessed among white women aged < 70 who were free of contraindications for recommended therapy, had stage I-III tumors, and survived >= 12 months. Hazard ratios (HRs) and 95% confidence intervals (CIs) for breast cancer death were estimated using Cox proportional hazards models. RESULTS: Included women represented 4635 patients and 449 breast cancer deaths. Women who did not receive radiotherapy (HR 2.3; 95% CI 1.2-4.4) or endocrine therapy (HR 2.0; 95% CI 1.0-4.0) as recommended by guidelines had an increased risk of breast cancer death, relative to those treated appropriately. Receipt of guideline-recommended therapy did not differ between Hispanic and NHW women for chemotherapy (84.2% vs. 81.3%, respectively), radiotherapy (89.2% vs. 91.1%), or endocrine therapy (89.2% vs. 85.8%), thus did not influence Hispanic survival disparities. CONCLUSIONS: Lack of guideline-recommended radiotherapy or endocrine therapy contributed to survival as strongly as other established prognostic indicators. Hispanic survival disparities in this population do not appear to be attributable to treatment differences. PMID- 29569019 TI - Prediction of breast cancer risk with volatile biomarkers in breath. AB - BACKGROUND: Human breath contains volatile organic compounds (VOCs) that are biomarkers of breast cancer. We investigated the positive and negative predictive values (PPV and NPV) of breath VOC biomarkers as indicators of breast cancer risk. METHODS: We employed ultra-clean breath collection balloons to collect breath samples from 54 women with biopsy-proven breast cancer and 124 cancer-free controls. Breath VOCs were analyzed with gas chromatography (GC) combined with either mass spectrometry (GC MS) or surface acoustic wave detection (GC SAW). Chromatograms were randomly assigned to a training set or a validation set. Monte Carlo analysis identified significant breath VOC biomarkers of breast cancer in the training set, and these biomarkers were incorporated into a multivariate algorithm to predict disease in the validation set. In the unsplit dataset, the predictive algorithms generated discriminant function (DF) values that varied with sensitivity, specificity, PPV and NPV. RESULTS: Using GC MS, test accuracy = 90% (area under curve of receiver operating characteristic in unsplit dataset) and cross-validated accuracy = 77%. Using GC SAW, test accuracy = 86% and cross validated accuracy = 74%. With both assays, a low DF value was associated with a low risk of breast cancer (NPV > 99.9%). A high DF value was associated with a high risk of breast cancer and PPV rising to 100%. CONCLUSION: Analysis of breath VOC samples collected with ultra-clean balloons detected biomarkers that accurately predicted risk of breast cancer. PMID- 29569020 TI - Potentially toxic elements in soil of the Khyber Pakhtunkhwa province and Tribal areas, Pakistan: evaluation for human and ecological risk assessment. AB - Potentially toxic elements (PTEs) contaminations in the soil ecosystem are considered as extremely hazardous due to toxicity, persistence and bioaccumulative nature. Therefore, this study was aimed to summarize the results of published PTEs in soil of Khyber Pakhtunkhwa and Tribal areas, Pakistan. Results were evaluated for the pollution quantification factors, including contamination factor (CF), pollution load index (PLI), ecological risk index (ERI) and human health risk assessment. The highest CF (797) and PLI (7.35) values were observed for Fe and ERI (857) values for Cd. Soil PTEs concentrations were used to calculate the human exposure for the risk assessment, including chronic or non-carcinogenic risks such as the hazard quotient (HQ) and carcinogenic or cancer risk (CR). The values of HQ were > 1 for the Cd, Co and Cr in Khyber Pakhtunkhwa and Tribal areas. Tribal areas showed higher values of ERI, HQ, and CR as compared to the Khyber Pakhtunkhwa that were attributed to the mining activities, weathering and erosion of mafic and ultramafic bedrocks hosting ophiolites. This study strongly recommends that best control measures need to be taken for soil PTEs with the intent to alleviate any continuing potential threat to the human health, property and environment, which otherwise could enter ecosystem and ultimately the living beings. Further studies are recommended to combat the soil PTEs concentrations and toxicity in the Tribal areas for a best picture of understanding the element effects on human, and environment can be achieved that will lead to a sustainable ecological harmony. PMID- 29569021 TI - Assessing oral health-related quality of life in children and adolescents: a systematic review and standardized comparison of available instruments. AB - OBJECTIVES: To obtain a systematic and standardized evaluation of the current evidence on development process, metric properties, and administration issues of oral health-related quality of life instruments available for children and adolescents. MATERIALS AND METHODS: A systematic search until October 2016 was conducted in PubMed, Embase, Lilacs, SciELO, and Cochrane databases. Articles with information regarding the development process, metric properties, and administration issues of pediatric instruments measuring oral health-related quality of life were eligible for inclusion. Two researchers independently evaluated each instrument applying the Evaluating Measures of Patient-Reported Outcomes (EMPRO) tool. An overall and seven attribute-specific EMPRO scores were calculated (range 0-100, worst to best): measurement model, reliability, validity, responsiveness, interpretability, burden, and alternative forms. RESULTS: We identified 18 instruments evaluated in 132 articles. From five instruments designed for preschoolers, the Early Childhood Oral Health Impact Scale (ECOHIS) obtained the highest overall EMPRO score (82.2). Of nine identified for schoolchildren and adolescents, the best rated instrument was the Child Perceptions Questionnaire 11-14 (82.1). Among the four instruments developed for any age, the Family Impact Scale (FIS) obtained the highest scores (80.3). CONCLUSION: The evidence supports the use of the ECOHIS for preschoolers, while the age is a key factor when choosing among the four recommended instruments for schoolchildren and adolescents. Instruments for specific conditions, symptoms, or treatments need further research on metric properties. CLINICAL RELEVANCE: Our results facilitate decision-making on the correct oral health-related quality of life instrument selection for any certain study purpose and population during the childhood and adolescence life cycle. PMID- 29569022 TI - Professionals' views on the development process of a structural collaboration between child and adolescent psychiatry and child welfare: an exploration through the lens of the life cycle model. AB - This study, as a part of a participatory action research project, reports the development process of an innovative collaboration between child and adolescent psychiatry and child welfare, for adolescent girls with multiple and complex needs. The findings emerge from a qualitative descriptive analysis of four focus groups with 30 professionals closely involved in this project, and describe the evolution of the collaborative efforts and outcomes through time. Participants describe large investments and negative consequences of rapid organizational change in the beginning of the collaboration project, while benefits of the intensive collaboration only appeared later. A shared person-centred vision and enhanced professionals' confidence were pointed out as important contributors in the evolution of the collaboration. Findings were compared to the literature and showed significant analogy with the life cycle model for shared service centres that describe the maturation of collaborations from a management perspective. These findings enrich the knowledge about the development process of collaboration in health and social care. In increasingly collaborative services, child and adolescent psychiatrists and policy makers should be aware that gains from a collaboration will possibly only be achieved in the longer term, and benefit from knowing which factors have an influence on the evolution of a collaboration project. PMID- 29569023 TI - Current perspectives on in vitro maturation and its effects on oocyte genetic and epigenetic profiles. AB - In vitro maturation (IVM), the maturation in culture of immature oocytes, has been used in clinic for more than 20 years. Although IVM has the specific advantages of low cost and minor side effects over controlled ovarian stimulation, the prevalence of IVM is less than 1% of routine in vitro fertilization and embryo transfer techniques in many reproductive centers. In this review, we searched the MEDLINE database for all full texts and/or abstract articles published in English with content related to oocyte IVM mainly between 2000 and 2016. Many different aspects of the IVM method may influence oocyte potential, including priming, gonadotrophin, growth factors, and culture times. The culture conditions of IVM result in alterations in the oocyte or cumulus cell transcriptome that are not observed under in vivo culture conditions. Additionally, epigenetic modifications, such as DNA methylation or acetylation, are also different between in vitro and in vivo cultured oocytes. In sum, current IVM technique is still not popular and requires more systematic and intensive research to improve its effects and applications. This review will help point our problems, supply evidence or clues for future improving IVM technique, thus assist patients for fertility treatment or preservation as an additional option. PMID- 29569024 TI - Soluble Fibrin Monomer Complex and Prediction of Cardiovascular Events in Atrial Fibrillation: The Observational Murcia Atrial Fibrillation Project. AB - BACKGROUND: Soluble fibrin monomer complex (SFMC) is a biomarker of fibrin formation abnormally elevated in clinical situations of hypercoagulability. OBJECTIVE: We investigated the association and predictive performance of SFMC for stroke, adverse cardiovascular events, cardiovascular mortality and all-cause mortality in a cohort of patients with atrial fibrillation (AF) receiving vitamin K antagonist (VKA) anticoagulant therapy. DESIGN: During the second semester of 2007, we included 1226 AF outpatients stable on VKAs (INR 2.0-3.0) over a period of 6 months. SFMC levels were assessed at baseline. During 6.5 (IQR 4.4-8.0) years of follow-up, we recorded all ischemic strokes, adverse cardiovascular events (composite of stroke, acute heart failure, acute coronary syndrome and cardiovascular death), cardiovascular deaths and all-cause deaths. PARTICIPANTS: All patients were recruited consecutively. We excluded patients with rheumatic mitral valves, prosthetic heart valves, acute coronary syndrome, stroke, hemodynamic instability, hospital admissions or surgical interventions within the preceding 6 months. MAIN MEASURES: SFMC levels were measured in plasma by immunoturbidimetry in an automated coagulometer (STALiatestFM, Diagnostica Stago, Asnieres, France). KEY RESULTS: We recorded 121 (1.52%/year) ischemic strokes, 257 (3.23%/year) cardiovascular events, 67 (0.84%/year) cardiovascular deaths and 486 (6.10%/year) all-cause deaths. SFMC >12 MUg/mL was not associated with stroke but was associated with higher risk of cardiovascular events (HR 1.72, 95% CI 1.31-2.26), cardiovascular mortality (HR 2.16, 95% CI 1.30-3.57) and all-cause mortality (HR 1.26, 95% CI 1.03-1.55). When SFMC >12 MUg/mL was added to the CHA2DS2-VASc, there were significant improvements in predictive performance, sensitivity and reclassification for adverse cardiovascular events (c-index: 0.645 vs. 0.660, p = 0.010; IDI = 0.013, p < 0.001; NRI = 0.121, p < 0.001) and cardiovascular mortality (c-index: 0.661 vs. 0.691, p = 0.006; IDI = 0.009, p = 0.049; NRI = 0.217, p < 0.001), but decision curves demonstrated a similar net benefit and clinical usefulness. CONCLUSIONS: In AF patients taking VKAs, high SFMC levels were associated with the risk of adverse cardiovascular events, cardiovascular mortality and all-cause mortality. The addition of SFMC to the CHA2DS2-VASc score improved its predictive performance for these outcomes, but failed to show an improvement in clinical usefulness. PMID- 29569025 TI - [Simultaneous fracture of the acromion and coracoid process : Rare variant of double disruption of the superior shoulder suspensory complex]. AB - INTRODUCTION: Simultaneous fracture of the acromion and coracoid process represents a double disruption of the superior shoulder suspensory complex (SSSC). To date, the two largest reported series have comprised five and eight cases. The aim of this study was to investigate the functional outcome in patients who sustained this rare injury and to provide a review of the relevant literature. MATERIAL AND METHODS: In this retrospective study, patients who were surgically treated between 2009 and 2014 were identified from medical records and the patients were asked to attend a follow-up examination. Functional results, measured as the Constant score and Disabilities of the Arm, Shoulder and Hand (DASH) score, were the main outcomes of the study. RESULTS: A total of six patients underwent surgery for this type of double disruption of the SSSC. All but one patient suffered a high-impact trauma with other associated injuries. The coracoid fracture was classified as type I according to Ogawa in all cases, and the acromion fracture was type III according to Kuhn in 5 out of 6 cases. At least one of the fracture sites was stabilized. Of the patients one showed a concurrent lateral clavicle fracture, representing a third disruption of the SSSC, and another had a fracture of the medial third of the clavicle, representing a strut fracture. In these cases, two fracture sites were operated on. At an average follow-up period of 47 months all but one fracture had healed. In one patient, asymptomatic non-union of the acromion was found. The average DASH score was 22 points and the average Constant score was 74 points. CONCLUSION: This rare injury pattern is usually caused by high-impact trauma, and concomitant injuries frequently occur. Nevertheless, surgical stabilization of at least one of the fracture sites showed satisfactory functional results. PMID- 29569027 TI - Polymeric nanoparticles for topical delivery of alpha and beta arbutin: preparation and characterization. AB - To investigate the use of chitosan nanoparticles (CS-TPP-NPs) as carriers for alpha- and beta-arbutin. In this study, CS-TPP-NPs containing alpha- and beta arbutin were prepared via the ionic cross-linking of CS and TPP and characterized for particle size, zeta potential, and dispersity index. The entrapment efficiency and loading capacity of various beta-arbutin concentrations (0.1, 0.2, 0.4, 0.5, and 0.6%) were also investigated. SEM, TEM FTIR, DSC and TGA analyses of the nanoparticles were performed to further characterize the nanoparticles. Finally, stability and release studies were undertaken to ascertain further the suitability of the nanoparticles as a carrier system for alpha- and beta-arbutin. Data obtained clearly indicates the potential for use of CS-TPP-NPs as a carrier for the delivery of alpha- and beta-arbutin. The size obtained for the alpha nanoparticles (alpha-arbutin CSNPs) ranges from 147 to 274 d.nm, with an increase in size with increasing alpha arbutin concentration. beta-arbutin nanoparticles (beta-arbutin CSNPs) size range was from 211.1 to 284 dn.m. PdI for all nanoparticles remained between 0.2-0.3 while the zeta potential was between 41.6 52.1 mV. The optimum encapsulation efficiency and loading capacity for 0.4% alpha arbutin CSNPs were 71 and 77%, respectively. As for beta-arbutin, CSNP optimum encapsulation efficiency and loading capacity for 0.4% concentration were 68 and 74%, respectively. Scanning electron microscopy for alpha-arbutin CSNPs showed a more spherical shape compared to beta-arbutin CSNPs where rod-shaped particles were observed. However, under transmission electron microscopy, the shapes of both alpha- and beta-arbutin CSNP nanoparticles were spherical. The crystal phase identification of the studied samples was carried out using X-ray diffraction (XRD), and the XRD of both alpha and beta-arbutin CSNPs showed to be more crystalline in comparison to their free form. FTIR spectra showed intense characteristic peaks of chitosan appearing at 3438.3 cm-1 (-OH stretching), 2912 cm-1 (-CH stretching), represented 1598.01 cm-1 (-NH2) for both nanoparticles. Stability studies conducted for 90 days revealed that both alpha- and beta arbutin CSNPs were stable in solution. Finally, release studies of both alpha- and beta-arbutin CSNPs showed a significantly higher percentage release in comparison to alpha- and beta-arbutin in their free form. Chitosan nanoparticles demonstrate considerable promise as a carrier system for alpha- and beta-arbutin, the use of which is anticipated to improve delivery of arbutin through the skin, in order to improve its efficacy as a whitening agent.

PMID- 29569029 TI - A Second Look at the Process of Occupational Feminization and Pay Reduction in Occupations. AB - Using the IPUMS-USA data for the years 1960-2015, this study examines trends in the effect of occupational feminization on occupational pay in the U.S. labor market and explores some of the mechanisms underlying these trends. The findings show that the (negative) association between occupational feminization and occupational pay level has declined, becoming insignificent in 2015. This trend, however, is reversed after education is controlled for at the individual as well as the occupational level. The two opposite trends are discussed in light of the twofold effect of education: (1) the entry of women into occupations requiring high education, and (2) the growing returns to education and to occupations with higher educational requirements. These two processes have concealed the deterioration in occupational pay following feminization. The findings underscore the significance of structural forms of gender inequality in general, and occupational devaluation in particular. PMID- 29569026 TI - The Genetic Landscape of Hypoplastic Left Heart Syndrome. AB - Hypoplastic left heart syndrome (HLHS) is one of the most lethal congenital heart defects, and remains clinically challenging. While surgical palliation allows most HLHS patients to survive their critical heart disease with a single ventricle physiology, many will suffer heart failure, requiring heart transplantation as the only therapeutic course. Current paradigm suggests HLHS is largely of hemodynamic origin, but recent findings from analysis of the first mouse model of HLHS showed intrinsic cardiomyocyte proliferation and differentiation defects underlying the left ventricular (LV) hypoplasia. The findings of similar defects of lesser severity in the right ventricle suggest this could contribute to the heart failure risks in surgically palliated HLHS patients. Analysis of 8 independent HLHS mouse lines showed HLHS is genetically heterogeneous and multigenic in etiology. Detailed analysis of the Ohia mouse line accompanied by validation studies in CRISPR gene-targeted mice revealed a digenic etiology for HLHS. Mutation in Sap130, a component of the HDAC repressor complex, was demonstrated to drive the LV hypoplasia, while mutation in Pcdha9, a protocadherin cell adhesion molecule played a pivotal role in the valvular defects associated with HLHS. Based on these findings, we propose a new paradigm in which complex CHD such as HLHS may arise in a modular fashion, mediated by multiple mutations. The finding of intrinsic cardiomyocyte defects would suggest hemodynamic intervention may not rescue LV growth. The profound genetic heterogeneity and oligogenic etiology indicated for HLHS would suggest that the genetic landscape of HLHS may be complex and more accessible in clinical studies built on a familial study design.

PMID- 29569031 TI - Molecular characterization of medulloblastomas with extensive nodularity (MBEN). AB - Medulloblastoma with extensive nodularity (MBEN) is a rare histological variant of medulloblastoma (MB). These tumors are usually occurring in the first 3 years of life and are associated with good prognosis. Molecular analyses of MBEN, mostly limited to single cases or small series, have shown that they always classify as sonic hedgehog (SHH)-driven MB. Here, we have analyzed 25 MBEN through genome-wide DNA methylation, copy-number profiling and targeted next generation sequencing. Results of these analyses were compared with molecular profiles of other SHH MB histological variants. As expected, the vast majority of MBEN (23/25) disclosed SHH-associated epigenetic signatures and mutational landscapes but, surprisingly, two MBEN were classified as Group 3/4 MB. Most MBEN classified as SHH MB displayed SHH-related and mutually exclusive mutations in either SUFU, or PTCH1, or SMO at similar frequencies. However, only SUFU mutations were also identified in the germ-line. Most of SUFU-associated MBEN eventually recurred but patients were treated successfully with second-line high dose chemotherapy. Altogether, our data show that risk stratification even for well-recognizable histologies such as MBEN cannot rely on histology alone but should include additional molecular analyses such as methylation profiling and DNA sequencing. For all patients with "MBEN" histology, we recommend sequencing SUFU and PTCH1 in the tumor as well as in the germ-line for further clinical stratification and choice of the optimal treatment strategy upfront. PMID- 29569032 TI - 2D speckle-tracking TTE-based quantitative classification of left ventricular myocardium in patients with hypertrophic cardiomyopathy by the presence or the absence of fibrosis and/or hypertrophy. AB - We used peak longitudinal strain (PLS) on TTE in HCM patients to differentiate LV myocardium (LVM) into the following 4 groups: group 1-no fibrosis or hypertrophy (>= 13 mm), group 2-no fibrosis but hypertrophy evident, group 3-fibrosis present but without hypertrophy, and group 4-both fibrosis and hypertrophy. Seventeen HCM patients (13 males, 56 +/- 16 years) underwent both 1.5 T CMR and TTE. On TTE, PLS (absolute values) for each LVM segment from 17 AHA-defined lesions was calculated. Of 289 LVM lesions, the numbers in each group, 1-4, were 156, 53, 39, and 41, respectively. PLS for LVM segments in group 1 (13.6 +/- 6.4%) were significantly greater than those in group 2 (8.5 +/- 4.9%, P < 0.001), group 3 (10.4 +/- 5.0%, P = 0.006), and group 4 (7.1 +/- 4.4%, P < 0.001). PLS for LVM segments in group 3 was significantly greater than those in group 4 (P = 0.016). However, significant differences in PLS in LVM between groups 2 and 3, and between 2 and 4 were not observed. Using regional PLS, we demonstrate successful differentiation of LVM in HCM patients for group 1 (LVM with zero fibrosis or hypertrophy) from LVM belonging to groups 2-4 and we also demonstrate successful differentiation of LVM with fibrosis present but without hypertrophy from LVM with both fibrosis and hypertrophy. However, it is not possible to differentiate between LVM with no fibrosis but hypertrophy evident and those with fibrosis present but without hypertrophy and also between LVM with no fibrosis but hypertrophy evident and those with both fibrosis and hypertrophy. Our findings have significant implications for the management of HCM patients. PMID- 29569033 TI - Decreased blood glucose at admission has a prognostic impact in patients with severely decompensated acute heart failure complicated with diabetes mellitus. AB - The prognostic impact of a decreased blood glucose level in acute heart failure (AHF) has not been sufficiently clarified. The data from 1234 AHF patients were examined in the present study. The blood glucose (BG) levels were evaluated at admission. The patients were divided into groups based on the following: with or without diabetes mellitus (DM), and BG level >= 200 mg/dl (elevated BG) or < 200 mg/dl (decreased BG). The elevated and decreased BG patients were further divided into another three groups: 200 mg/ml <= BG < 300 mg/dl (mild-elevated), 300 mg/ml <= BG < 400 mg/dl (moderate-elevated) and BG >= 400 mg/ml (severe-elevated); and 150 mg/ml <= BG < 200 mg/dl (mild-decreased), 100 mg/ml <= BG < 150 mg/dl (moderate-decreased) and BG < 100 mg/ml (severe-decreased), respectively. The DM patients had a significantly poorer mortality than the non-DM patients. The prognosis was different between patients with elevated or decreased BG. In DM patients with elevated BG, the severe-elevated patients had a significantly poorer prognosis than moderate- and mild-elevated patients. In the DM patients with decreased BG, the severe-decreased patients had a significantly poorer prognosis than those moderate- and mild-decreased patients. The multivariate Cox regression model showed that a severe-decreased [hazard ratio (HR) 3.245, 95% confidence interval (CI) 1.271-8.282] and severe-elevated (HR 2.300, 95% CI 1.143 4.628) status were independent predictors of 365-day mortality in AHF patients with DM. The mortality was high among AHF patients with DM. Furthermore, both severe hyperglycemia and hypoglycemia were independent predictors of the mortality in patients with AHF complicated with DM. PMID- 29569035 TI - [Radiological imaging of acute infectious and non-infectious enterocolitis]. AB - BACKGROUND: Computed tomography (CT) is often used as the initial diagnostic test in patients with inflammatory and infectious types of enterocolitis. The differential diagnosis is broad, including infectious, non-infectious and vascular causes, which have substantially different management strategies. Although a definitive diagnosis often relies on endoscopic biopsy results, stool culture results or other clinical features, radiologists often help to guide the diagnosis. OBJECTIVES: This article reviews the CT appearance of different infectious and inflammatory forms of enterocolitis. General and specific intramural and extramural CT findings in the small bowel and colon are discussed. Added focus is placed on distribution patterns and medication side effects that can act as important diagnostic clues. RESULTS: Infectious enterocolitis is due to bowel inflammation caused by bacteria, viruses, or parasites, which show a preferential localization. Pancolitis can be seen with Clostridium difficile with the relatively specific CT finding of the "giraffe coat" sign. Inflammatory enterocolitis can be primary (inflammatory bowel disease, vasculitis) or secondary (radiation therapy, graft versus host disease etc.). Ischemic colitis and enteritis can result from arterial compromise, low flow states that globally reduce perfusion or venous insufficiency. The CT appearance varies depending on the cause, the time of onset and grade of reperfusion. CONCLUSION: Knowledge of characteristic mural and extramural CT of MRI findings, geographic distributions and therapy effects help to guide the differential diagnostics in inflammatory and infectious types of enterocolitis.

AB - We aimed to compare the usefulness of plasma levels of B-type natriuretic peptide (BNP) for long-term risk stratification among patients with heart failure (HF) with preserved left ventricular ejection fraction (LVEF) (HFpEF), borderline HFpEF, and HF with reduced LVEF (HFrEF) in the same HF cohort. In the CHART-2 Study (N = 10,219), we categorized 4301 consecutive Stage C/D HF patients (mean age 68.7 years, female 32.4%) into 3 groups: HFpEF (LVEF >= 50%, N = 2893), borderline HFpEF (LVEF 40-50%, N = 666), and HFrEF (LVEF <= 40%, N = 742). During the median 6.3-year follow-up, all-cause deaths occurred in 887 HFpEF, 330 borderline HFpEF, and 330 HFrEF patients. Although median BNP levels increased from HFpEF, borderline HFpEF to HFrEF (85.3, 126 and 208 pg/ml, respectively, P < 0.001), the relationship between log2 BNP levels and the mortality risk was comparable among the 3 groups. As compared with patients with BNP < 30 pg/ml, those with 30-99, 100-299 and >= 300 pg/ml had comparably increasing mortality risk among the 3 groups (hazard ratio 2.5, 4.7 and 7.8 in HFpEF, 2.1, 4.2 and 7.0 in borderline HFpEF, and 3.0, 4.7 and 9.5 in HFrEF, respectively, all P < 0.001). BNP levels have comparable prognostic impact among HFpEF, borderline HFpEF, and HFrEF patients.

AB - PURPOSE: To analyse the influence of CT-based depth correction in the assessment of split renal function in potential living kidney donors. METHODS: In 116 consecutive living kidney donors preoperative split renal function was assessed using the CT-based depth correction. Influence on donor side selection and postoperative renal function of the living kidney donors were analyzed. Linear regression analysis was performed to identify predictors of postoperative renal function. RESULTS: A left versus right kidney depth variation of more than 1 cm was found in 40/114 donors (35%). 11 patients (10%) had a difference of more than 5% in relative renal function after depth correction. Kidney depth variation and changes in relative renal function after depth correction would have had influence on side selection in 30 of 114 living kidney donors. CT depth correction did not improve the predictability of postoperative renal function of the living kidney donor. In general, it was not possible to predict the postoperative renal function from preoperative total and relative renal function. In multivariate linear regression analysis, age and BMI were identified as most important predictors for postoperative renal function of the living kidney donors. CONCLUSIONS: Our results clearly indicate that concerning the postoperative renal function of living kidney donors, the relative renal function of the donated kidney seems to be less important than other factors. A multimodal assessment with consideration of all available results including kidney size, location of the kidney and split renal function remains necessary.

AB - This invited narrative review emphasizes the role of MAO-B inhibition in the drug portfolio for dopamine substitution in patients with Parkinson's disease. Neuronal and glial MAO-B inhibition contributes to more stable levels of dopamine and other biogenic amines in the synaptic cleft. Accordingly, symptomatic effects of MAO-B inhibition for a limited amelioration of impaired motor behaviour and wearing-off phenomena in patients with Parkinson's disease are well proven, even when MAO-B inhibitors are only applied together with dopamine agonists. Delay of disease progression by MAO-B inhibition is under debate despite positive experimental findings. This discussion does not consider, that levodopa, respectively, dopamine agonists, are substrates, respectively, inhibitors of the ABCB1 (P-gp, MDR1, and CD243) transporter system. It supports toxin efflux over the blood-brain barrier. ABCB1 transporters have a limited capacity. MAO-B inhibitors do not weaken it. Treatment with MAO-B inhibitors is advantageous as it enables sparing of dopamine agonist and levodopa dosing.

AB - The transient receptor potential melastatin 4 (TRPM4) channel has been suggested to play a key role in the treatment of ischemic stroke. However, in vivo evaluation of TRPM4 channel, in particular by direct channel suppression, is lacking. In this study, we used multimodal imaging to assess edema formation and quantify the amount of metabolically functional brain salvaged after a rat model of stroke reperfusion. TRPM4 upregulation in endothelium emerges as early as 2 h post-stroke induction. Expression of TRPM4 channel was suppressed directly in vivo by treatment with siRNA; scrambled siRNA was used as a control. T2-weighted MRI suggests that TRPM4 inhibition successfully reduces edema by 30% and concomitantly salvages functionally active brain, measured by 18F-FDG-PET. These in vivo imaging results correlate well with post-mortem 2,3,5 triphenyltetrazolium chloride (TTC) staining which exhibits a 34.9% reduction in infarct volume after siRNA treatment. Furthermore, in a permanent stroke model, large areas of brain tissue displayed both edema and significant reductions in metabolic activity which was not shown in transient models with or without TRPM4 inhibition, indicating that tissue salvaged by TRPM4 inhibition during stroke reperfusion may survive. Evans Blue extravasation and hemoglobin quantification in the ipsilateral hemisphere were greatly reduced, suggesting that TRPM4 inhibition can improve BBB integrity after ischemic stroke reperfusion. Our results support the use of TRPM4 blocker for early stroke reperfusion. PMID- 29569040 TI - Recurrent Hypoglycemia Exacerbates Cerebral Ischemic Damage in Diabetic Rats via Enhanced Post-Ischemic Mitochondrial Dysfunction. AB - Diabetes significantly increases the risk of stroke and post-stroke mortality. Recurrent hypoglycemia (RH) is common among diabetes patients owing to glucose lowering therapies. Earlier, we showed that RH in a rat model of insulin dependent diabetes exacerbates cerebral ischemic damage. Impaired mitochondrial function has been implicated as a central player in the development of cerebral ischemic damage. Hypoglycemia is also known to affect mitochondrial functioning. The present study tested the hypothesis that prior exposure of insulin-treated diabetic (ITD) rats to RH exacerbates brain damage via enhanced post-ischemic mitochondrial dysfunction. In a rat model of streptozotocin-induced diabetes, we evaluated post-ischemic mitochondrial function in RH-exposed ITD rats. Rats were exposed to five episodes of moderate hypoglycemia prior to the induction of cerebral ischemia. We also evaluated the impact of RH, both alone and in combination with cerebral ischemia, on cognitive function using the Barnes circular platform maze test. We observed that RH exposure to ITD rats leads to increased cerebral ischemic damage and decreased mitochondrial complex I activity. Exposure of ITD rats to RH impaired spatial learning and memory. Our results demonstrate that RH exposure to ITD rats potentially increases post ischemic damage via enhanced post-ischemic mitochondrial dysfunction. PMID- 29569042 TI - "Nobody came to help": interviews with women convicted of filicide in Malaysia. AB - Although filicide is of serious concern, it is poorly understood in Malaysia. Our interviews with health and policy professionals revealed that they attribute responsibility for filicide to women's failure to comply with social norms and religious teachings. This research sought to understand the meaning of and background to filicide from the perspectives of women who have been convicted of filicide in Malaysia. In-depth interviews were conducted in person with all eligible and consenting women convicted of filicide and incarcerated in prisons or forensic psychiatric institutions. Women's accounts were translated into English and analysed using interpretative phenomenological analysis and interpreted using narrative theory. Interviews with nine women convicted of filicide yielded evidence that others were implicated in the crime but punished less severely, if at all, and that the women had experienced lifelong gender based violence and marginalisation with minimal access to health and social care. These findings illuminate an inadequately understood phenomenon in Malaysia and reveal why existing strategies to reduce filicide, which reflect key stakeholders' views, have had little impact. They reveal the pervasive harm of violence against women and children and its link to filicide. PMID- 29569043 TI - Paliperidone and pregnancy-an evaluation of the German Embryotox database. AB - Schizophrenic or schizoaffective disorders often occur in early adulthood and thus affect women of childbearing age. For paliperidone information about reproductive safety is wanting. Therefore, we evaluated data from the German Embryotox pharmacovigilance institute regarding paliperidone therapy during pregnancy. The German Embryotox pharmacovigilance institute offers risk assessment on drug use in pregnancy and documents the outcome of more than 3500 drug-exposed pregnancies per year. In our study, we analyze the outcome of all pregnancies with paliperidone exposure, which have been assessed by our institute between January 2007 and June 2016. Of the 17 prospectively assessed pregnancies, 14 resulted in 15 live-born children (including one pair of twins). None of the infants presented with major congenital malformations. There were two spontaneous abortions at gestational weeks 6 and 11, respectively, and one elective termination due to personal reasons. Sixty-five percent of the pregnant women smoked cigarettes throughout pregnancy, 17% consumed alcohol. Five children were born prematurely (< 37 gestational weeks) and four were small for gestational age, each group including the twins. The results of our study suggest that paliperidone may be administered during pregnancy. The increased rate of prematurity and small for gestational age children can at least partially be explained by other risk factors. Psychiatric and obstetric close monitoring as well as additional medical and social support are recommended to ensure a healthy pregnancy course in patients with a severe mental illness. PMID- 29569044 TI - Impact of a training program on adherence to recommendations for care of venous lines in internal medicine departments in Spain. AB - A high percentage of venous lines (VLs) are placed in non-ICU patients, particularly those treated in the internal medicine department (IMD). We assessed adherence to VL care after a training program aimed at nurses and clinicians attending patients admitted to Spanish IMDs. We performed a multicenter prospective observational point prevalence study in 14 Spanish IMDs in 2013 and 2016. We included all adult patients (> 18 years) admitted to IMDs on the study day and reviewed nursing records for patients with VL in place before and after a 1-year training program during 2015. Answers from an interview with head nurses of the IMDs regarding commonly used practices in the daily management of VLs were also compared. A total of 638 and 693 patients were seen during each period, respectively, and 530 and 598 patients had >= 1 VL implanted (83.1 vs. 86.3%). Catheters were considered unnecessary in 12.8 and 15.0% of cases (p = 0.28). Daily recording of the need for catheter use increased from 43.8 to 71.8% (p < 0.001). Furthermore, daily monitoring of the insertion site remained very frequent (94.4 vs. 92.2%; p = 0.16). The date of insertion was recorded in 86.3 and 85.5% of cases (p = 0.73), and no combination of closed connectors with open caps increased from 74.8 to 90.3% (p < 0.001). Overall, head nurses' knowledge improved in 4 out of 14 recommendations assessed (28.6%). A simple and easy program for training on management of VLs in Spanish IMDs was associated with improved quality of care. PMID- 29569047 TI - Alterations in resting-state gamma activity in patients with schizophrenia: a high-density EEG study. AB - Alterations of EEG gamma activity in schizophrenia have been reported during sensory and cognitive tasks, but it remains unclear whether changes are present in resting state. Our aim was to examine whether changes occur in resting state, and to delineate those brain regions where gamma activity is altered. Furthermore, we wanted to identify the associations between changes in gamma activity and psychopathological characteristics. We studied gamma activity (30-48 Hz) in 60 patients with schizophrenia and 76 healthy controls. EEGs were acquired in resting state with closed eyes using a high-density, 256-channel EEG-system. The two groups were compared in absolute power measures in the gamma frequency range. Compared to controls, in patients with schizophrenia the absolute power was significantly elevated (false discovery rate corrected p < 0.05). The alterations clustered into fronto-central and posterior brain regions, and were positively associated with the severity of psychopathology, measured by the PANSS. Changes in gamma activity can lead to disturbed coordination of large scale brain networks. Thus, the increased gamma activity in certain brain regions that we found may result in disturbances in temporal coordination of task free/resting-state networks in schizophrenia. Positive association of increased gamma power with psychopathology suggests that altered gamma activity provides a contribution to symptom presentation. PMID- 29569046 TI - In vitro antibacterial effects of statins against bacterial pathogens causing skin infections. AB - With financial considerations impeding research and development of new antibiotics, drug repurposing (finding new indications for old drugs) emerges as a feasible alternative. Statins are extensively prescribed around the world to lower cholesterol, but they also possess inherent antimicrobial properties. This study identifies statins with the greatest potential to be repurposed as topical antibiotics and postulates a mechanism of action for statins' antibacterial activity. Using broth microdilution, the direct antibacterial effects of all seven parent statins currently registered for human use and three selected statin metabolites were tested against bacterial skin pathogens Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Serratia marcescens. Simvastatin and pitavastatin lactone exerted the greatest antibacterial effects (minimum inhibitory concentrations of 64 and 128 MUg/mL, respectively) against S. aureus. None of the statins tested were effective against E. coli, P. aeruginosa, or S. marcescens, but simvastatin hydroxy acid acid might be active against S. aureus, E. coli, and S. marcescens at drug concentrations > 256 MUg/mL. It was found that S. aureus may exhibit a paradoxical growth effect when exposed to simvastatin; thus, treatment failure at high drug concentrations is theoretically probable. Through structure-activity relationship analysis, we postulate that statins' antibacterial action may involve disrupting the teichoic acid structures or decreasing the number of alanine residues present on Gram-positive bacterial cell surfaces, which could reduce biofilm formation, diminish bacterial adhesion to environmental surfaces, or impede S. aureus cell division. PMID- 29569045 TI - Recent advances in rapid pathogen detection method based on biosensors. AB - As strain variation and drug resistance become more pervasive, the prevention and control of infection have been a serious problem in recent years. The detection of pathogen is one of the most important parts of the process of diagnosis. Having a series of advantages, such as rapid response, high sensitivity, ease of use, and low cost, biosensors have received much attention and been studied deeply. Moreover, relying on its characteristics of small size, real time, and multiple analyses, biosensors have developed rapidly and used widely and are expected to be applied for microbiological detection in order to meet higher accuracy required by clinical diagnosis. The main goal of this contribution is not to simply collect and list all papers related to pathogen detection based on biosensors published recently, but to discuss critically the development and application of many kinds of biosensors such as electrochemical (amperometric, impedimetric, potentiometric, and conductometric), optical (fluorescent, fibre optic and surface plasmon resonance), and piezoelectric (quartz crystal microbalances and atomic force microscopy) biosensors in pathogen detection as well as the comparisons with the existing clinical detection methods (traditional culture, enzyme-linked immunosorbent assay, polymerase chain reaction, and mass spectrometry). PMID- 29569048 TI - A Metagenome-Based Investigation of Gene Relationships for Non-Substrate Associated Microbial Phosphorus Cycling in the Water Column of Streams and Rivers. AB - Phosphorus (P) is a nutrient of primary importance in all living systems, and it is especially important in streams and rivers which are sensitive to anthropogenic P inputs and eutrophication. Microbes are accepted as the primary mineralizers and solubilizers of P improving bioavailability for organisms at all trophic levels. Here, we use a genomics approach with metagenome sequencing of 24 temperate streams and rivers representing a total P (TP) gradient to identify relationships between functional genes, functional gene groupings, P, and organisms within the P biogeochemical cycle. Combining information from network analyses, functional groupings, and system P levels, we have constructed a System Relational Overview of Gene Groupings (SROGG) which is a cohesive system level representation of P cycle gene and nutrient relationships. Using SROGG analysis in concert with other statistical approaches, we found that the compositional makeup of P cycle genes is strongly correlated to environmental P whereas absolute abundance of P genes shows no significant correlation to environmental P. We also found orthophosphate (PO43-) to be the dominant factor correlating with system P cycle gene composition with little evidence of a strong organic phosphorous correlation present even in more oligotrophic streams. PMID- 29569049 TI - CT for evaluation of acute pericardial emergencies in the ED. AB - Acute pericardial emergencies may present with acute chest pain. Although complete diagnosis and physiological effects of acute pericardial disease may require a combination of different imaging, CT plays a critical role in identifying the cause of chest pain in the ED. Many of these pericardial diseases can be fatal unless emergent treatment is obtained. The presentation can often be non-specific and symptoms can be overlapping with other diseases originating in the thorax or abdomen. Optimizing the CT scan is imperative when acute pericardial disease is suspected from clinical examination or preliminary imaging. The interpreting radiologist needs to be aware of the different entities which represent acute pericardial emergencies requiring urgent therapeutic intervention. Time is the essence, the clock is ticking, and every minute counts! PMID- 29569050 TI - Anaerobic digestion performance of sweet potato vine and animal manure under wet, semi-dry, and dry conditions. AB - Sweet potato vine (SPV) is an abundant agricultural waste, which is easy to obtain at low cost and has the potential to produce clean energy via anaerobic digestion (AD). The main objectives of this study were to reveal methane production and process stability of SPV and the mixtures with animal manure under various total solid conditions, to verify synergetic effect in co-digestion of SPV and manure in AD systems, and to determine the kinetics characteristics during the full AD process. The results showed that SPV was desirable feedstock for AD with 200.22 mL/g VSadded of methane yield in wet anaerobic digestion and 12.20 Lmethane/Lworking volume in dry anaerobic digestion (D-AD). Synergistic effects were found in semi-dry anaerobic digestion and D-AD with each two mixing feedstock. In contrast with SPV mono-digestion, co-digestion with manure increased methane yield within the range of 14.34-49.11% in different AD digesters. The values of final volatile fatty acids to total alkalinity (TA) were below 0.4 and the values of final pH were within the range of 7.4-8.2 in all the reactors, which supported a positive relationship between carbohydrate hydrolysis and methanogenesis during AD process. The mathematical modified first order model was applied to estimate substrate biodegradability and methane production potential well with conversion constant ranged from 0.0003 to 0.0953 1/day, which indicated that co-digestion increased hydrolysis efficiency and metabolic activity. This work provides useful information to improve the utilization and stability of digestion using SPV and livestock or poultry manure as substrates. PMID- 29569051 TI - Induction and relocalization of telomeric repeat-containing RNAs during diauxic shift in budding yeast. AB - Telomeres are maintained in a heterochromatic state that represses transcription of subtelomeric genes, a phenomenon known as telomere position effect. Nevertheless, telomeric DNA is actively transcribed, leading to the synthesis of telomeric repeat-containing noncoding RNA or TERRA. This nuclear noncoding RNA has been proposed to play important roles at telomeres, regulating their silencing, capping, repair and elongation by telomerase. In the budding yeast Saccharomyces cerevisiae, TERRA accumulation is repressed by telomeric silencing and the Rat1 exonuclease. On the other hand, telomere shortening promotes expression of TERRA. So far, little is known about the biological processes that induce TERRA expression in yeast. Understanding the dynamics of TERRA expression and localization is essential to define its function in telomere biology. Here, we aim to study the dynamics of TERRA expression during yeast cell growth. Using live-cell imaging, RNA-FISH and quantitative RT-PCR, we show that TERRA expression is induced as yeast cells undergo diauxic shift, a lag phase during which yeast cells switch their metabolism from anaerobic fermentation to oxidative respiration. This induction is transient as TERRA levels decrease during post-diauxic shift. The increased expression of TERRA is not due to the shortening of telomeres or increased stability of this transcript. Surprisingly, this induction is coincident with a cytoplasmic accumulation of TERRA molecules. Our results suggest that TERRA transcripts may play extranuclear functions with important implications in telomere biology and add a novel layer of complexity in the interplay between telomere biology, metabolism and stress response. PMID- 29569052 TI - Managing Couple Conflict During Prenatal Counseling Sessions: An Investigation of Genetic Counselor Experiences and Perceptions. AB - Research shows couple conflict occurring during prenatal genetic counseling sessions may be challenging for some genetic counselors. Yet, no study has explored couple conflict in depth. The current study investigated genetic counselors' experiences and perceptions of the nature and context of couple conflict in prenatal sessions and counselor conflict management strategies. Sixteen prenatal genetic counselors recruited through the National Society of Genetic Counselors participated in semi-structured phone interviews asking about how they recognize couple conflict; topics that trigger conflict and when it occurs; individual, cultural, and situational factors associated with conflict; conflict management strategies; and specific examples from their practice. Inductive and cross-case comparison methods revealed a number of themes. Genetic counselors recognize couple conflict through non-verbal and verbal cues, and conflict can occur at any time, particularly during decision-making about testing and test results and during results review of an affected pregnancy. Factors associated with conflict include cultural customs, age, emotional state, religious beliefs, and being forced to attend counseling. Participants identified 23 conflict management strategies classified into five themes: facilitate decision-making, encourage couple expression, act within one's scope of practice, provide psychosocial support, and support the identified patient. Counselors emphasized that their strategies are couple dependent. Patients may benefit from genetic counselors assessing couple conflict and intervening when it impedes genetic counseling goals. Clinical examples from this study may contribute to informing genetic counselor practice, program curricula, and continuing education workshops.

AB - PURPOSE: Assessment of limitations in the perfusion dynamics of skeletal muscle may provide insight in the pathophysiology of exercise intolerance in, e.g., heart failure patients. Power doppler ultrasound (PDUS) has been recognized as a sensitive tool for the detection of muscle blood flow. In this volunteer study (N = 30), a method is demonstrated for perfusion measurements in the vastus lateralis muscle, with PDUS, during standardized cycling exercise protocols, and the test-retest reliability has been investigated. METHODS: Fixation of the ultrasound probe on the upper leg allowed for continuous PDUS measurements. Cycling exercise protocols included a submaximal and an incremental exercise to maximal power. The relative perfused area (RPA) was determined as a measure of perfusion. Absolute and relative reliability of RPA amplitude and kinetic parameters during exercise (onset, slope, maximum value) and recovery (overshoot, decay time constants) were investigated. RESULTS: A RPA increase during exercise followed by a signal recovery was measured in all volunteers. Amplitudes and kinetic parameters during exercise and recovery showed poor to good relative reliability (ICC ranging from 0.2-0.8), and poor to moderate absolute reliability (coefficient of variation (CV) range 18-60%). CONCLUSIONS: A method has been demonstrated which allows for continuous (Power Doppler) ultrasonography and assessment of perfusion dynamics in skeletal muscle during exercise. The reliability of the RPA amplitudes and kinetics ranges from poor to good, while the reliability of the RPA increase in submaximal cycling (ICC = 0.8, CV = 18%) is promising for non-invasive clinical assessment of the muscle perfusion response to daily exercise. PMID- 29569056 TI - The role of long-range coupling in crayfish swimmeret phase-locking. AB - During forward swimming, crayfish and other long-tailed crustaceans rhythmically move four pairs of limbs called swimmerets to propel themselves through the water. This behavior is characterized by a particular stroke pattern in which the most posterior limb pair leads the rhythmic cycle and adjacent swimmerets paddle sequentially with a delay of roughly 25% of the period. The neural circuit underlying limb coordination consists of a chain of local modules, each of which controls a pair of limbs. All modules are directly coupled to one another, but the inter-module coupling strengths decrease with the distance of the connection. Prior modeling studies of the swimmeret neural circuit have included only the dominant nearest-neighbor coupling. Here, we investigate the potential modulatory role of long-range connections between modules. Numerical simulations and analytical arguments show that these connections cause decreases in the phase differences between neighboring modules. Combined with previous results from a computational fluid dynamics model, we posit that this phenomenon might ensure that the resultant limb coordination lies within a range where propulsion is optimal. To further assess the effects of long-range coupling, we modify the model to reflect an experimental preparation where synaptic transmission from a middle module is blocked, and we generate predictions for the phase-locking properties in this system. PMID- 29569055 TI - Collision activity during training increases total energy expenditure measured via doubly labelled water. AB - PURPOSE: Collision sports are characterised by frequent high-intensity collisions that induce substantial muscle damage, potentially increasing the energetic cost of recovery. Therefore, this study investigated the energetic cost of collision based activity for the first time across any sport. METHODS: Using a randomised crossover design, six professional young male rugby league players completed two different 5-day pre-season training microcycles. Players completed either a collision (COLL; 20 competitive one-on-one collisions) or non-collision (nCOLL; matched for kinematic demands, excluding collisions) training session on the first day of each microcycle, exactly 7 days apart. All remaining training sessions were matched and did not involve any collision-based activity. Total energy expenditure was measured using doubly labelled water, the literature gold standard. RESULTS: Collisions resulted in a very likely higher (4.96 +/- 0.97 MJ; ES = 0.30 +/- 0.07; p = 0.0021) total energy expenditure across the 5-day COLL training microcycle (95.07 +/- 16.66 MJ) compared with the nCOLL training microcycle (90.34 +/- 16.97 MJ). The COLL training session also resulted in a very likely higher (200 +/- 102 AU; ES = 1.43 +/- 0.74; p = 0.007) session rating of perceived exertion and a very likely greater (- 14.6 +/- 3.3%; ES = - 1.60 +/- 0.51; p = 0.002) decrease in wellbeing 24 h later. CONCLUSIONS: A single collision training session considerably increased total energy expenditure. This may explain the large energy expenditures of collision-sport athletes, which appear to exceed kinematic training and match demands. These findings suggest fuelling professional collision-sport athletes appropriately for the "muscle damage caused" alongside the kinematic "work required". PMID- 29569057 TI - [Mechanical pupillary dilatation using rings in small pupils during cataract surgery : Video article]. AB - OBJECTIVE: The purpose of mechanical pupillary dilatation in small pupils is a sufficient visualization of the lens to be able to perform capsulorhexis, phacoemulsification and intraocular lens implantation. INDICATIONS: The indications for mechanical dilatation are fulfilled in patients where a sufficient pharmacological preoperative pupil dilatation is not possible. SURGICAL TECHNIQUE: During routine cataract surgery specific foldable rings can be employed to dilate the pupil with the appropriate injector under viscoelastic substances. These rings are carefully placed at the pupillary margin until circular pupillary dilatation up to 6-7 mm is achieved. After intraocular lens implantation and before removing the viscoelastic substance the rings are slowly folded into the injector and then removed. The surgical technique is demonstrated in detail with the help of a video of the operation, which is available online. RESULTS: Mechanical pupillary dilatation was possible in all patients studied (n = 14), which allowed uncomplicated phacoemulsification and intraocular lens implantation. For both ring systems studied the mean pupillary dilatation was 6.6 mm. At the end of surgery, the pupillary diameter was 4.89 mm using a Malyugin ring (MST, Redmond, Washington, USA) and 4.93 mm with an I-ring (Visitec, Waltham, MA, USA; P > 0.05). Small lesions at the pupillary margin or pigment dispersion during implantation or explantation depended mostly on the individual patient situation and not on the ring used. CONCLUSION: Mechanical pupillary dilatation with rings allows sufficient dilatation to perform cataract surgery. Both the Malyugin ring and the I-ring achieved smooth and atraumatic pupillary dilatation.

PMID- 29569058 TI - Plumbagin, a vitamin K3 analogue ameliorate malaria pathogenesis by inhibiting oxidative stress and inflammation. AB - Plumbagin, a vitamin K3 analogue is the major active constituent in several plants including root of Plumbago indica Linn. This compound has been shown to exhibit a wide spectrum of pharmacological activities. The present investigation was to evaluate the ameliorative effects of plumbagin (PL) against severe malaria pathogenesis due to involvement of oxidative stress and inflammatory response in Plasmodium berghei infected malaria in mice. Malaria pathogenesis was induced by intra-peritoneal injection of P. berghei infected red blood cells into the Swiss albino mice. PL was administered orally at doses of 3, 10 and 30 mg/kg/day following Peter's 4 day suppression test. Oral administration of PL showed significant reduction of parasitaemia and increase in mean survival time. PL treatment is also attributed to significant increase in the blood glucose and haemoglobin level when compared with vehicle-treated infected mice. Significant inhibition in level of oxidative stress and pro-inflammation related markers were observed in PL treated group. The trend of inhibition in oxidative stress markers level after oral treatment of PL was MPO > LPO > ROS in organ injury in P. berghei infected mice. This study showed that plumbagin is able to ameliorate malaria pathogenesis by augmenting anti-oxidative and anti-inflammatory mechanism apart from its effect on reducing parasitaemia and increasing mean survival time of malaria-induced mice. PMID- 29569061 TI - Expression of Genes Associated with Nickel Resistance in Red Oak (Quercus rubra) Populations from a Metal Contaminated Region. AB - Although many studies have reported mechanisms of resistance to metals in herbaceous species, there is very little information on metal coping strategy in hardwood species such as Quercus rubra. The main objective of this study was to determine the expression of genes associated with nickel resistance in red oak (Q. rubra) populations from metal contaminated and uncontaminated sites in the Northern Ontario. Six genes associated with nickel resistances in model and non model plants were targeted. Differential expressions of these genes were observed in Q. rubra from all the sites, but association between metal contamination and gene expression was not established. This suggests that the bioavailable amounts of metals found in metal contaminated soils in mining sites in northern Ontario and likely in many mining regions around the world cannot trigger a genetic response in higher plant species. PMID- 29569060 TI - Predictors of portal and splenic vein thrombosis after laparoscopic splenectomy: a retrospective analysis of a single-center experience. AB - PURPOSE: Laparoscopic splenectomy (LS) has become the standard operative approach for splenectomy. Portal or splenic vein thrombosis (PSVT) is a serious and common complication after LS, and lethal complications of PSVT can occur when the portal vein is completely occluded by portal vein thrombosis (PVT). We aimed to clarify the predictors of PSVT after LS and to determine which of them were also predictors of PVT. METHODS: A total of 56 consecutive patients who underwent elective LS were enrolled in this study. The patients were divided into two groups based on the presence or absence of PSVT after LS. In addition, patients with PSVT were divided into two groups: a PVT group and a non-PVT group. The preoperative and intraoperative clinical data were compared among the groups. RESULTS: Thirty (53.6%) patients developed PSVT. The splenic vein diameter was the most useful predictor for the development of PSVT, and 10 mm was an accurate splenic vein diameter cut-off value for use as a predictive factor for PSVT. In addition, the splenic vein diameter was the most useful predictor of the development of PVT from splenic vein thrombosis (SVT), and 14 mm was found to be an accurate cut-off value. CONCLUSION: PSVT is a common postoperative complication that is identified on enhanced computed tomography. The splenic vein diameter is not only a predictor of PSVT but also of the development of PVT from SVT.

AB - The present study reports partial sequences of a group of genes used as exposure and effect biomarkers of organic contaminants and/or heavy metals in Syacium gunteri. In order to isolate these sequences, cDNA was used to amplify fragments between 200 and 800 bp, which were then cloned and sequenced. The sequences presented high percentages of identity with genes involved in the metabolism of xenobiotic biotransformation (cytochrome P4501A and glutathione S-transferase), oxidative stress (catalase, glutathione reductase, glutathione peroxidase and superoxide dismutase), reproductive system (vitellogenin) and with the tumor suppressor protein p53 reported in the GenBank database. Subsequently, from the deduced sequence of amino acids of each fragment, their tridimensional structure was predicted, using homologous proteins from the Protein Data Base. This study generates an important base of molecular biomarkers for the monitoring of environmental health in the Gulf of Mexico.

AB - OBJECTIVE: Reconstruction of tendon integrity to maintain glenohumeral joint centration and hence to restore shoulder functional range of motion and to reduce pain. INDICATIONS: Isolated or combined full-thickness subscapularis tendon tears (>=upper two-thirds of the tendon) without both substantial soft tissue degeneration and cranialization of the humeral head. CONTRAINDICATIONS: Chronic tears of the subscapularis tendon with higher grade muscle atrophy, fatty infiltration, and static decentration of the humeral head. SURGICAL TECHNIQUE: After arthroscopic three-sided subscapularis tendon release, two double-loaded suture anchors are placed medially to the humeral footprint. Next to the suture passage, the suture limbs are tied and secured laterally with up to two knotless anchors creating a transosseous-equivalent repair. POSTOPERATIVE MANAGEMENT: The affected arm is placed in a shoulder brace with 20 degrees of abduction and slight internal rotation for 6 weeks postoperatively. Rehabilitation protocol including progressive physical therapy from a maximum protection phase to a minimum protection phase is required. Overhead activities are permitted after 6 months. RESULTS: While previous studies have demonstrated superior biomechanical properties and clinical results after double-row compared to single-row and transosseous fixation techniques, further mid- to long-term clinical investigations are needed to confirm these findings.

AB - The essay examines Robin Cook's (1977) Coma and Priscille Sibley's (2013) The Promise of Stardust that dramatize the reified and disposable status of the brain dead patients who are classified as nonpersons. The essay argues that the man machine entanglement as depicted in the novels constructs a deterritorialized and entangled form of subjectivity that intervenes in the dominant biomedical understanding of personhood and agency that we notionally associate with a conscious mind. The essay concludes its arguments by discussing Alexander Beliaev's (1925) Professor Dowell's Head which depicts human subjectivity as an essentially embodied and distributive phenomenon and interrogates the Cartesian mind body dualism embedded in the dominant biomedical narratives.

AB - Burkholderia pseudomallei causes melioidosis, a life-threatening infection in both humans and animals. Water is an important reservoir of the bacteria and may serve as a source of environmental contamination leading to infection. B. pseudomallei has an unusual ability to survive in water for a long period. This paper investigates physicochemical properties of water associated with the presence of B. pseudomallei in water supply in small ruminant farms in Peninsular Malaysia. Physicochemical properties of water samples taken from small ruminant farms that included temperature, pH, dissolved oxygen (DO2), optical density (OD), and chemical oxygen demand (COD) were measured after which the samples were cultured for B. pseudomallei. Multivariable logistic regression model revealed that slightly acidic water pH and higher COD level were significantly associated with the likelihood of the B. pseudomallei presence in the water.

AB - We study the spin- and valley-dependent energy band and transport property of silicene under a periodic potential, where both spin and valley degeneracies are lifted. It is found that the Dirac point, miniband, band gap, anisotropic velocity, and conductance strongly depend on the spin and valley indices. The extra Dirac points appear as the voltage potential increases, the critical values of which are different for electron with different spins and valleys. Interestingly, the velocity is greatly suppressed due to the electric field and exchange field, other than the gapless graphene. It is possible to achieve an excellent collimation effect for a specific spin near a specific valley. The spin and valley-dependent band structure can be used to adjust the transport, and perfect transmissions are observed at Dirac points. Therefore, a remarkable spin and valley polarization is achieved which can be switched effectively by the structural parameters. Importantly, the spin and valley polarizations are greatly enhanced by the disorder of the periodic potential.

AB - A bipartite begomovirus was identified from a Boehmeria leiophylla plant sample exhibiting yellow mosaic symptoms collected in Nabanhe National Nature Reserve, Xishuangbanna, Yunnan, China. Five complete DNA-A and four DNA-B genome sequences were obtained by rolling-circle amplification (RCA), cloned, and sequenced. All DNA-A sequences were determined to be 2759 nucleotides in size, sharing 99.9% 100% nucleotide sequence identity with each other. The DNA-B sequences were comprised of 2673 nucleotides, sharing 98.6-100% nucleotide sequence identity with each other. Genomic organization of the begomovirus was typical of Old World bipartite begomoviruses. Sequence analysis revealed 81.84% nucleotide sequence identity to tomato leaf curl Hsinchu virus (ToLCHsV) from China for the DNA A component and 67.23% identity to the squash leaf curl China virus (SLCCNV) from India for the DNA B component. The sequence comparisons suggest that this bipartite begomovirus represents a novel species for which we propose the name "Ramie yellow mosaic virus".

AB - More and more virulent phages that are fundamental materials for phage therapy have been isolated, characterized and categorized on GenBank. Phage ST31 infecting Escherichia coli H21 was isolated from wastewater and sequenced using an Illumina Hiseq system. Opening reading frames were identified using PHASTER and predicted using BLASTp analysis. Genomic analyses revealed that this was a virulent phage containing a circular double-stranded DNA and that the complete genome consisted of 39,693 nucleotides with an average GC content of 49.98 %. This study may provide possible alternative materials for phage therapy. PMID- 29569070 TI - Detection and genetic characterization of porcine astroviruses in piglets with and without diarrhea in Thailand. AB - Porcine astrovirus (PAstV) is widely distributed and highly prevalent among pigs, nevertheless its clinical significance remains unclear as it can be detected in both diarrheic and in healthy pigs. Information about the prevalence, clinical significance and molecular characterization of PAstV in Thailand is not available. This study investigated the prevalence of PAstV in 488 fecal samples collected from piglets with and without diarrhea in 28 pig farms in northern and central parts of Thailand using RT-PCR. The overall prevalence of PAstV infection was 6.5% (32/488), of which 21/251 (8.4%) were in diarrheic and 11/237 (4.6%) were in healthy pigs. Of 32 positive samples, 46.9% were positive for PAstV alone whereas 53.1% were co-infected with porcine group A rotavirus (PRVA). A phylogenetic analysis of the partial RNA-dependent RNA polymerase/capsid genes revealed two lineages of PAstV strains detected in this study. PAstV4 was the most dominant genotype (92%), followed by PAstV2 (8%). This study revealed for the first time that PAstV4 and PAstV2 were circulating in Thailand with PAstV4 as the most dominant genotype in pig herds in northern and central parts of Thailand. PMID- 29569071 TI - Coloproctology procedure clinic: a novel service developed to reduce suffering of patients with bleeding per rectum. AB - AIMS: Evaluation of the role and impact of introducing a dedicated coloproctology procedure clinic in tertiary referral colorectal unit. METHODS: A retrospective analysis of 126 consecutive patients managed in the coloproctology clinic between March2015 and September 2016 was carried out. All patients were preselected for attendance based on symptom-based protocol. RESULTS: Based on the information available in GP referrals, 126 patients with bleeding per rectum with low risk of cancer were re-triaged from the general outpatient to dedicated coloproctology procedure clinic. Those patients accounted for 14% of waiting list. The average waiting time to attend clinic was 27 months from referral to undergoing definitive procedure. A proctoscopy or/and rigid sigmoidoscopy was performed in patients. Seventy-nine (89.7%) patients were completely managed and discharged after attending their first visit. Sixty-seven (76%) patients had 2nd- or 3rd degree haemorrhoids and were treated with rubber band ligation (RBL) or phenol injection in outpatient setting. Two patients had an anal fissure and were managed conservatively with medication. After clinic, follow-up was through telephone clinic. This avoids attendance physically in the hospital. Symptoms persisted in nine patients and were subsequently scheduled for colonoscopy, three had benign polyps. With the introduction of the procedure clinic, the waiting time from referral to treatment was reduced from 27 to 6 months (p < 0.05). CONCLUSIONS: Establishing a dedicated "Coloproctology procedure clinic" is an effective strategy in reducing number of hospital visits per patient and hospital waiting list. This innovative clinic reduces utilisation of precious endoscopy unit resources. This ultimately will improve endoscopy efficiency. PMID- 29569073 TI - Impact of colorectal surgeon case volume on outcomes and applications to quality improvement. AB - PURPOSE: To evaluate the impact of surgeon case volumes on procedural, financial, and clinical outcomes in colorectal surgery and apply findings to improve hospital care quality. METHODS: A retrospective review was performed using 2013 2014 administrative data from a large hospital system in Southeast U.S. region; univariate and multivariable regression analyses were used to explore the impact of surgeon case volume on outcomes. RESULTS: One thousand one hundred ninety patients were included in this 2-year study. When compared with low-volume surgeons (LVS) (< 14 cases in 2 years), the high-volume surgeons (HVS) (> 34 cases) were estimated per case to have shorter cut-to-close time in the operation room by 79 min, ([95% CI 58 to 99]), lower total hospitalization cost by $4314, ([95% CI $2261 to $6367]), and shorter post-surgery and overall length of stay by 0.92 days, ([95% CI 0.50 to 1.35]) and 1.27 days ([95% CI 0.56 to 1.98]), respectively. The HVS also showed a higher tendency to choose a laparoscopic approach over an open approach, with an odds ratio of 3.16 ([95% CI 1.23 to 8.07]). When compared with medium-volume surgeons (MVS) (14-34 cases), the HVS were estimated per case to have shorter cut-to-close time in the operation room by 62 min ([95% CI 37 to 87]). Surgeon case volumes had no statistically significant impact on outcomes including in-hospital mortality, 30-day readmission, blood utilization, and surgical site infection (SSI). CONCLUSIONS: Surgeon case volume had positive impacts on procedural, financial, and clinical outcomes and this finding may be used to improve hospital's quality of care. PMID- 29569072 TI - Posttranslational modifications of CENP-A: marks of distinction. AB - Centromeres are specialized chromosome domain that serve as the site for kinetochore assembly and microtubule attachment during cell division, to ensure proper segregation of chromosomes. In higher eukaryotes, the identity of active centromeres is marked by the presence of CENP-A (centromeric protein-A), a histone H3 variant. CENP-A forms a centromere-specific nucleosome that acts as a foundation for centromere assembly and function. The posttranslational modification (PTM) of histone proteins is a major mechanism regulating the function of chromatin. While a few CENP-A site-specific modifications are shared with histone H3, the majority are specific to CENP-A-containing nucleosomes, indicating that modification of these residues contribute to centromere-specific function. CENP-A undergoes posttranslational modifications including phosphorylation, acetylation, methylation, and ubiquitylation. Work from many laboratories have uncovered the importance of these CENP-A modifications in its deposition at centromeres, protein stability, and recruitment of the CCAN (constitutive centromere-associated network). Here, we discuss the PTMs of CENP-A and their biological relevance. PMID- 29569074 TI - Acaricidal and repellent effects of Cnidium officinale-derived material against Dermanyssus gallinae (Acari: Dermanyssidae). AB - The acaricidal activity of a methanolic extract and fractions from the rhizome of Cnidium officinale against Dermanyssus gallinae adults was investigated. The C. officinale methanolic extract exhibited 100% acaricidal activity after 48 h of treatment at a dose of 4000 ppm. The acaricidal constituents of the plant were sequentially partitioned with several solvents and then purified using silica gel column chromatography and high-performance liquid chromatography. Gas chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy revealed (Z)-ligustilide as a constituent of C. officinale. Acaricidal activity was examined in three experimental tests (spray, fumigation and contact), with the spraying method being the most effective. The methanolic extract of C. officinale showed both contact and fumigant activities, though only fumigant activity was observed with (Z)-ligustilide. The fumigant effects of the methanolic extract and (Z)-ligustilide caused 86.5 and 62.6% mortality, respectively, of D. gallinae adults at 48 h. Among (Z)-ligustilide, acaricides (bifenthrin, cypermethrin and spinosad) and butylidenephthalide, bifenthrin displayed the highest acaricidal activity, and the activity of butylidenephthalide was 2.3-fold higher than that of (Z)-ligustilide. These results suggest that C. officinale-derived material can be used for the development of a control agent for D. gallinae. PMID- 29569075 TI - Contrasting structures of plant-mite networks compounded by phytophagous and predatory mite species. AB - Differences in the feeding habits between phytophagous and predatory species can determine distinct ecological interactions between mites and their host plants. Herein, plant-mite networks were constructed using available literature on plant dwelling mites from Brazilian natural vegetation in order to contrast phytophagous and predatory mite networks. The structural patterns of plant-mite networks were described through network specialization (connectance) and modularity. A total of 187 mite species, 65 host plant species and 646 interactions were recorded in 14 plant-mite networks. Phytophagous networks included 96 mite species, 61 host plants and 277 interactions, whereas predatory networks contained 91 mite species, 54 host plants and 369 interactions. No differences in the species richness of mites and host plants were observed between phytophagous and predatory networks. However, plant-mite networks composed of phytophagous mites showed lower connectance and higher modularity when compared to the predatory mite networks. The present results corroborate the hypothesis that trophic networks are more specialized than commensalistic networks, given that the phytophagous species must deal with plant defenses, in contrast to predatory mites which only inhabit and forage for resources on plants. PMID- 29569076 TI - Serious mental illness and negative substance use consequences among adults on probation. AB - BACKGROUND: Adults on probation are at greater risk of both using substances and having a mental disorder compared to the general population. Several theories explain the relationship between substance use and poor mental health. However, the interaction between substance use, mental health, and substance-related consequences is not well understood. A better understanding of this relationship may help treatment programs become more responsive to people with serious mental illness (SMI). METHOD: The current study used interview data from 313 adults on probation who reported recent substance use. We examined associations between SMI risk, substance use, and substance use consequences. RESULTS: A substantial proportion of the sample (37.5%) screened at risk of having a SMI. Adjusting for type and amount of substance use, those who screened at risk of having a SMI reported more negative substance use consequences. Significant interaction effects were observed between use of alcohol or opiates and SMI risk. Alcohol use was associated with more negative substance use consequences among those at risk of SMI, while opiate use was associated with more consequences among those not at risk. CONCLUSIONS: Programs are sorely needed to identify and treat adults with comorbid substance use and mental health symptoms, particularly for adults in the justice system. Clinicians should carefully consider how mental health may interact with substance use to exacerbate consequences. PMID- 29569078 TI - Anemia Due to ABO Incompatibility in a Neonate. PMID- 29569077 TI - Protective Effect of Quercetin in LPS-Induced Murine Acute Lung Injury Mediated by cAMP-Epac Pathway. AB - Quercetin (Que) as an abundant flavonol element possesses potent antioxidative properties and has protective effect in lipopolysaccharide (LPS)-induced acute lung injury (ALI), but the specific mechanism is still unclear, so we investigated the effect of Que from in vivo and in vitro studies and the related mechanism of cAMP-PKA/Epac pathway. The results in mice suggested that Que can inhibit the release of inflammatory cytokine, block neutrophil recruitment, and decrease the albumin leakage in dose-dependent manners. At the same time, Que can increase the cAMP content of lung tissue, and Epac content, except PKA. The results in epithelial cell (MLE-12) suggested that Que also can inhibit the inflammatory mediators keratinocyte-derived chemokines release after LPS stimulation; Epac inhibitor ESI-09 functionally antagonizes the inhibitory effect of Que; meanwhile, PKA inhibitor H89 functionally enhances the inhibitory effect of Que. Overexpression of Epac1 in MLE-12 suggested that Epac1 enhance the effect of Que. All those results suggested that the protective effect of quercetin in ALI is involved in cAMP-Epac pathway. PMID- 29569079 TI - Exercise Capacity Assessment by the Modified Shuttle Walk Test and its Correlation with Biochemical Parameters in Obese Children and Adolescents. AB - OBJECTIVES: To evaluate exercise capacity of obese children and adolescents compared with normal-weight individuals and to investigate possible correlations with blood biochemical parameters. METHODS: In this study, children and adolescents between 6 and 18 y were included and divided into control (eutrophic) and obese groups according to body mass index (BMI). Data were collected regarding demographic, anthropometric, waist circumference and exercise capacity through the Modified Shuttle Walk Test (MSWT). In the obese group, biochemical parameters in the blood (total cholesterol, HDL, LDL, triglycerides and glucose) were evaluated, and a physical activity questionnaire was applied. RESULTS: Seventy seven participants were included; 27 in the control group and 50 obese. There was no significant difference between the two groups regarding sample characteristics, except for body weight, BMI and waist circumference. Most obese children presented results of biochemical tests within the desirable limit, though none were considered active. There was a significant exercise capacity reduction (p < 0.001) in the obese group compared to control subjects. Positive correlations were identified for the MSWT with age and height, and a negative correlation with BMI. However, there were no correlations with the biochemical parameters analyzed. CONCLUSIONS: Obese children and adolescents have reduced exercise capacity when compared to normal individuals. The MSWT performance seems to have a negative association with BMI, but is not correlated with blood biochemical parameters.

PMID- 29569081 TI - Identification of a melatonin receptor type 1A gene (AccMTNR1A) in Apis cerana cerana and its possible involvement in the response to low temperature stress. AB - It is known that melatonin plays an indispensable role in the defense against some environment-induced stresses. The melatonin receptor (MTNR) is also closely linked to the environmental stress response in mammals. However, little is known about the function of the MTNR in insects, including honeybees. In this study, we identified a MTNR from Apis cerana cerana named AccMTNR1A, which contained a typical seven-transmembrane domain common to this family of receptors. A subcellular localization analysis showed that AccMTNR1A was localized in the cytomembrane. Additionally, we found that cold stress apparently boosted AccMTNR1A transcription, indicating that AccMTNR1A possibly connects to the cold stress response. The knockdown of AccMTNR1A attenuated the expression level of some genes associated with the cold stress response, suggesting that AccMTNR1A likely plays an analogous role with these genes during low temperature stress response. Moreover, silencing of AccMTNR1A also suppressed the transcription of some antioxidant genes, prompting the possibility that the response of AccMTNR1A to cold stress response may be related to antioxidant signaling pathways. Collectively, the findings presented here provide evidence that AccMTNR1A may play essential roles in protecting Apis cerana cerana from cold stress. PMID- 29569082 TI - Long-Acting Injectable Second-Generation Antipsychotics: An Update and Comparison Between Agents. AB - Schizophrenia is a chronic medical condition with periods of remission and relapses over a patient's lifetime. Antipsychotic medications represent the mainstay of treatment for this disease. Long-acting injectable (LAI) formulations of antipsychotics are an attractive alternative to their oral counterparts, as they enhance patient adherence. A number of second-generation antipsychotics (SGAs) are available in LAI formulations. These include paliperidone, aripiprazole, olanzapine, and risperidone. This article reviews the most recently developed and approved of these formulations-aripiprazole monohydrate, aripiprazole lauroxil, and paliperidone palmitate. While all were initially available as once-monthly formulations, a paliperidone palmitate 3-monthly injection formulation has been approved and is the first LAI agent to extend the dosing administration beyond the typical monthly time period. In addition, aripiprazole lauroxil every 6-week and 8-week administration preparations have been developed. LAI preparations of the SGAs have all demonstrated superiority over placebo and are comparable to their oral counterparts in terms of safety and tolerability, if injection site reactions are not taken into account. First generation antipsychotic LAI preparations (e.g., haloperidol decanoate) have recently been compared with SGA LAI agents, and both formulations demonstrated comparable efficacy with the expected adverse events seen with each drug. Despite their availability, barriers to the use of LAIs remain. Education of both patients and clinicians on the use of LAI formulations and the continued development of these agents are important steps in ensuring these medications are available to the patients they would be most likely to benefit. PMID- 29569083 TI - Attention-deficit/hyperactivity disorder children exhibit an impaired accommodative response. AB - PURPOSE: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common paediatric neurobehavioural disorders causing multiple functional impairments in children. Based on the relationship between the neural system that controls attention and ocular dynamics, the present study compares the magnitude and variability of accommodation between a group of non-medicated ADHD children and an age-matched control group. METHODS: The magnitude and variability of the accommodative response were objectively measured in 36 children using the WAM 5500 autorefractometer for 90 consecutive seconds at three static viewing distances (500, 40, and 20 cm). Participants were divided into ADHD (n = 18) or control (n = 18) groups based on clinically validated criteria. RESULTS: Children with ADHD exhibited higher lags of accommodation (p = 0.024), increasing at closer viewing distances, in comparison to the control group. Marginal statistical differences were found for the variability of accommodation (p = 0.066), with the ADHD group showing a trend towards higher variability. Our analysis showed that the magnitude and variability of accommodation did not vary over time between groups (p > 0.05). CONCLUSIONS: Our data suggest that children with ADHD have a less accurate accommodative response. These results provide a new ocular index that could help to clarify the relationship between accommodative response and attentional deficits, which could have a direct impact on the academic, cognitive, and visual performance of ADHD children. PMID- 29569084 TI - Screening organometallic thiophene containing thiosemicarbazone ruthenium (II/III) complexes as potential anti-tumour agents. AB - The new ruthenium (III) complex has been synthesized and characterized by elemental analysis, FT-IR, UV-Vis, EI-Mass, EPR spectroscopy, and magnetic susceptibility measurement. Cytotoxic effects of organoruthenium (II/III) complexes 1a, 1b, and 2a, and their ligands (TSC1 and TSC2) in cultured human ovarian (A2780, SKOV-3, and OVCAR-3) and colon (DLD, CCD18Co, and Caco-2) cells have been investigated comparing reactivity of the Ru (II/III) complexes and their free TSC ligands. The complexes exhibit higher cytotoxicity in three cancer cell lines than in normal cells. The binding with CT-DNA and BSA of the all complexes were weak compared with their ligand in spite of the cellular uptake of these complexes into the cytoplasm and then nucleus while their cytotoxic effects were vice versa. All the results showed that Complex 1b has more efficient cytotoxicity on the colon cancer cells than ovarian cancer cells. However, Complex 2a is a better drug candidate especially for antitumor therapy of metastasized ovarian cancer. PMID- 29569086 TI - Pediatric cerebellar pilocytic astrocytoma presenting with spontaneous intratumoral hemorrhage. AB - Pilocytic astrocytomas (PAs) are benign glial tumors and one of the most common childhood posterior fossa tumors. Spontaneous intratumoral hemorrhage in PAs occurs occasionally, in about 8-20% of cases. Cerebellar hemorrhages in pediatric population are rare and mainly due to head injuries, rupture of vascular malformations, infections, or hematological diseases. We have investigated the still controversial and unclear pathophysiology underlying intratumoral hemorrhage in PAs. Bleeding in low-grade tumors might be related to structural abnormalities and specific angio-architecture of tumor vessels, such as degenerative mural hyalinization, "glomeruloid" endothelial proliferation, presence of encased micro-aneurysms, and glioma-induced neoangiogenesis. The acute hemorrhagic presentation of cerebellar PA in childhood although extremely uncommon is of critical clinical importance and necessitates promptly treatment. We described a case of hemorrhagic cerebellar PA in a 9-year-old child and reviewed the English-language literature that reported spontaneous hemorrhagic histologically proven cerebellar PA in pediatric patients (0-18 years). According to our analysis, the mortality was not related to symptom onset, tumor location, hemorrhage distribution, presence of acute hydrocephalous, and timing of surgery, while the GCS at hospital admission resulted to be the only statistically significant prognostic factor affecting survival outcome. The abrupt onset of signs and symptoms of acute hydrocephalous and consequent raised intracranial pressure are life-threatening conditions, which need emergent medical and neurosurgical treatments. At a later time, the identification of posterior fossa hemorrhage etiology is crucial to select the appropriate treatment and address the surgical strategy, optimizing the postoperative results. PMID- 29569087 TI - Reversal of retinal pigment epithelial detachment after cessation of topical travoprost therapy. AB - PURPOSE: To report the rare incidence of retinal pigment epithelial detachment (RPED) followed by topical travoprost therapy and its subsequent reattachment after cessation of the drug. METHODS: A 60-year-old male presented with gradual loss of vision in both eyes and distorted images in right eye. He gave a history of visiting an ophthalmologist a week ago for a routine eye examination. His previous reports revealed best-corrected visual acuity (BCVA) of 6/6, N6 in both eyes with raised intraocular pressures. A diagnosis of primary open-angle glaucoma was made and prescribed topical travoprost 0.004% eye drops. This patient's subsequent visit with diagnosis and treatment is mentioned in this case report. RESULTS: On examination, his BCVA was found to be 6/36, N12 and 6/6, N6 in right and left eyes, respectively. Optical coherence tomography (OCT) macular scan revealed RPED involving fovea in the right eye and inferotemporal to fovea in the left eye. Patient was advised to discontinue topical travoprost and started brinzolamide 1% eye drops. Ten-day follow-up visit revealed partially resolved RPED by OCT with 6/9 and 6/6 visual acuity in the right and left eyes, respectively. After 1 month, reversal of RPED was noted in OCT with 6/6 vision in both eyes. CONCLUSION: Hence, clinicians should be aware of this rare incidence of RPED followed by travoprost therapy. First case of RPED following travoprost therapy and complete reattachment upon withdrawal is reported here in this case report. PMID- 29569085 TI - The NMR contribution to protein-protein networking in Fe-S protein maturation. AB - Iron-sulfur proteins were among the first class of metalloproteins that were actively studied using NMR spectroscopy tailored to paramagnetic systems. The hyperfine shifts, their temperature dependencies and the relaxation rates of nuclei of cluster-bound residues are an efficient fingerprint of the nature and the oxidation state of the Fe-S cluster. NMR significantly contributed to the analysis of the magnetic coupling patterns and to the understanding of the electronic structure occurring in [2Fe-2S], [3Fe-4S] and [4Fe-4S] clusters bound to proteins. After the first NMR structure of a paramagnetic protein was obtained for the reduced E. halophila HiPIP I, many NMR structures were determined for several Fe-S proteins in different oxidation states. It was found that differences in chemical shifts, in patterns of unobserved residues, in internal mobility and in thermodynamic stability are suitable data to map subtle changes between the two different oxidation states of the protein. Recently, the interaction networks responsible for maturing human mitochondrial and cytosolic Fe-S proteins have been largely characterized by combining solution NMR standard experiments with those tailored to paramagnetic systems. We show here the contribution of solution NMR in providing a detailed molecular view of "Fe-S interactomics". This contribution was particularly effective when protein-protein interactions are weak and transient, and thus difficult to be characterized at high resolution with other methodologies.

PMID- 29569088 TI - Visceral adiposity index (VAI), a powerful predictor of incident hypertension in prehypertensives. AB - Prehypertension (defined by The Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure, JNC 7) is relevant to a higher cardiovascular risk than normotensives. Early intervention in this particular population is essential to avoid progression into hypertension (HTN). This study is to explore whether visceral adiposity index (VAI) can strongly predict the incidence of HTN in community-based prehypertensives. A prospective observational cohort study was conducted from September 2011 to June 2012 in urban communities of Chengdu, Sichuan Province, China. 780 subjects (male 320, female 460) were evaluated on anthropometrical indices, blood pressure, blood samples, brachial-ankle pulse wave velocity, of whom 360 prehypertensives (male 160, female 200) were recruited for a 5-year follow-up. Overall, 97 subjects (male 37, female 60) developed HTN. The risk for developing HTN in the future increases with increasing VAI levels. The OR of the upper quartile is 3.719 (95% CI 1.481-9.338, P = 0.005) after adjusting for confounders. The ROC results reveal that VAI is not considered superior to other indices on account of the significant overlapping confidence intervals. The area under the curves (AUC) of Model 5 (combination of VAI and WC) is significantly higher than BMI, WC and WHR (P < 0.05). The AUC of Model 4 (combination of VAI and BMI) is found to be significantly higher than BMI and WHR (P < 0.05), and is also higher than WC in all subject groups and in the male subgroup, but not in the female subgroup. VAI at baseline is an independent risk factor and early predictor of incident HTN in prehypertensives. The predictive value is not stronger than other traditional obesity indices (BMI, WC and WHR); however, it is superior to the latter by combining VAI and WC. Namely, VAI may help identify individuals at high risk of evolving into HTN in this particular population.

AB - Toxic alcohols are a group of substances containing a hydroxyl group not meant to be ingested. They are the cause of a significant number of accidental and non accidental exposures. Toxic alcohol poisoning can be associated with a significant degree of morbidity and mortality if not promptly recognized and treated. This review describes the clinical presentation and an approach to the recognition and management for toxic alcohol poisoning. Toxic alcohols classically refer to a group of alcohols not meant for ingestion. Methanol, ethylene glycol, and isopropyl alcohol are readily available in common hardware and household materials. Toxic alcohols are ingested for a variety of reasons including accidental exposures, intentional inebriation, homicide and suicide. The patient with an altered mental status or concerning history warrants consideration of this potentially deadly ingestion. Treatment considerations include alcohol dehydrogenase blockade and hemodialysis. Toxic alcohol poisoning can be an elusive diagnosis. This review evaluates toxic alcohol poisoning signs and symptoms and an approach to diagnosis and management.

AB - The aim of this study was to evaluate the effect of increasing concentrate supplementation levels on the intake, nutrient digestibility, and performance of crossbred steers during the dry period of the year. The experiment was developed on Princesa do Mateiro farm, in the municipality of Ribeirao do Largo, located in the southwest region of Bahia State, Brazil. Forty uncastrated male crossbred (1/2 Holstein-Zebu) steers with an average body weight (BW) of 232.55 +/- 24.97 kg were distributed into four treatments in a completely randomized design with ten replicates. The animals were managed in an experimental area formed by Brachiaria brizantha cv. Marandu, in an intermittent grazing system. Treatments consisted of the following supplementation levels: 0.2% BW, with 60% crude protein (CP); 0.3% BW, with 40% CP; 0.4% BW, with 30% CP; and 0.5% BW, with 24% CP. The intakes of forage dry matter in kg/day and %BW and neutral detergent fiber corrected for ash and protein (NDFap) in %BW decreased linearly, whereas the intake of non-fibrous carbohydrates corrected for ash and protein in kg/day and average daily gain increased linearly. Therefore, the use of supplementation at 0.5% BW (24% crude protein) to provide gains of up to 0.500 kg/day is recommended for grazing steers during the post-weaning period in the dry season of the year. PMID- 29569092 TI - The impact of health on wages: evidence for Europe. AB - This paper analyses the effects of health on wages in sixteen European countries using production frontier methodology. It is assumed that workers have a potential income/productivity which basically depends on their human capital, but due to several health problems, situations could exist where workers fail to reach their potential income frontier. The estimation of a true-random-effects model allows us to conclude that the potential hourly wage of workers is significantly influenced by their level of education and their job experience. However, health problems, especially those strongly influencing work activities, contribute towards an individual not attaining the potential income which would otherwise be guaranteed by their human capital endowment. Suffering a strong limitation reduces gross wage per hour by 6.1%. This wage reduction is also observed in the case of a weak limitation, but here the wage difference with respect to workers without any limitation is 2.6%. Additionally, other factors, such as being a woman, the economic cycle or having a temporary contract, appear to distance an individual from their wage frontier. PMID- 29569093 TI - Interaction Between Hepatocellular Carcinoma and Hepatitis C Eradication With Direct-acting Antiviral Therapy. AB - PURPOSE OF REVIEW: The approval of direct-acting antiviral (DAA) therapy has revolutionized hepatitis C virus (HCV) treatment. However, the publication of a study from Barcelona in 2016 raised concern for an increased risk of recurrence of hepatocellular carcinoma (HCC) after potentially curative therapy in patients receiving DAAs. This article reviews the current literature on the interaction between HCC and hepatitis C eradication with DAAs. RECENT FINDINGS: Following publication of the initial observation in 2016, a number of studies have looked at the impact of active HCC on the success of antiviral therapy, as well as that of treatment with DAAs on both the occurrence and recurrence of HCC. The presence of active HCC decreases sustained virologic response (SVR) rates with DAAs. However, SVR rates improve in patients who have achieved complete radiological response or are treated post transplantation. With respect to occurrence of HCC after DAAs, many small single-center studies without a control group have documented high incidence. The rates are also higher when compared to those of historical controls treated with interferon, but these patients are not comparable because DAA-treated population is more likely to have advanced fibrosis or decompensation. In large studies that have included a control group (patients treated concurrently who did not achieve SVR), a decrease in the occurrence of HCC has been demonstrated. With regard to recurrence of HCC, while smaller single-center studies have shown an increase, larger studies with control group have not replicated those findings. However, methodological limitations in the published studies limit our ability to make a firm conclusion on both the occurrence and recurrence of HCC after DAA therapy. The presence of active HCC decreases treatment success rates with DAAs. Therefore, it is recommended that treatment of HCV in patients with HCC be deferred till there is complete radiological response. Though there are major limitations with the currently published studies, the data does not support an increase in the occurrence or recurrence of HCC after DAA therapy. PMID- 29569094 TI - Focal intra-cavotricuspid isthmus atrial tachycardias occurring after typical atrial flutter ablation: incidence and electrocardiographic and electrophysiological characteristics. AB - PURPOSE: Focal atrial tachycardias (ATs) from the septal cavotricuspid isthmus (CTI) occurring after successful CTI ablation can mimic typical atrial flutter (tAFL). This study investigated the incidence, and electrocardiographic and electrophysiological characteristics of these ATs. METHODS: Among 1082 consecutive patients undergoing successful CTI ablation without any congenital heart diseases, 7 were diagnosed with focal ATs originating from the septal CTI that occurred a median of 74 days after the CTI ablation. RESULTS: The electrocardiographic characteristics of the ATs were similar to those of the tAFLs. The AT's cycle length was never shorter than and often similar to that of tAFLs. The activation patterns along the tricuspid annulus during the ATs were the same as those of tAFLs in 4 patients with foci adjacent to the CTI line, and centrifugal from foci around the coronary sinus (CS) ostium in 3. Entrainment pacing from the lateral CTI during the ATs revealed a manifest fusion and long post-pacing interval. Entrainment pacing from the lateral CTI during the ATs revealed that the atrial electrograms recorded from the CS and high-lateral right atrium were orthodromically captured, while that from the proximal CS revealed that the atrial electrograms recorded from the CS and lateral right atrium were antidromically captured without manifest fusion. CONCLUSIONS: Focal intra-CTI ATs with a microreentrant mechanism very rarely occurred after successful CTI ablation. The electrocardiographic and electrophysiological characteristics of these ATs were similar to those of tAFLs. Overdrive pacing from the lateral CTI and proximal CS was helpful for distinguishing these ATs from recurrent tAFLs. PMID- 29569095 TI - Interventions and Strategies to Improve Oral Anticoagulant Use in Patients with Atrial Fibrillation: A Systematic Review of Systematic Reviews. AB - INTRODUCTION: Anticoagulation therapy is the fundamental approach for stroke prevention in atrial fibrillation (AF) patients. Numerous systematic reviews comparing anticoagulation strategies have been published. We aim to summarize the efficacy and safety evidence of these strategies in AF patients from previously published systematic reviews. METHODS: We searched PubMed, EMBASE and Cochrane library from inception to Feb 24th, 2017, to identify systematic reviews and meta analyses of randomized controlled trials that assessed interventions or strategies to improve oral anticoagulant use in AF patients. RESULTS: Thirty-four systematic reviews were eligible for inclusion but only 11 were included in the qualitative analyses, corresponding to 40 unique meta-analyses, as the remaining systematic reviews had overlapping primary studies. There was insufficient evidence to support the efficacy of genotype-guided dosing and pharmacist-managed anticoagulation clinics for stroke prevention in AF patients. Conversely, patient's self-management and novel oral anticoagulants (NOACs), in general were superior to warfarin for preventing stroke and reducing mortality. All interventions showed comparable risk of major bleeding with warfarin. CONCLUSION: Findings from this overview support the superiority of NOACs and patient's self management for preventing stroke in AF patients. However, uncertainties remain on the benefits of genotype-guided dosing and pharmacist-managed anticoagulation clinics due to poor quality evidence, and future research is warranted. PMID- 29569096 TI - Did Antonio Vallisneri (1661-1730) really describe frontal sinus osteoma? Unexpected insights for paleo-neuroparasitology. AB - It has been believed for a long time that the Paduan scholar Antonio Vallisneri (1661-1730) described the second historical case of the frontal sinus osteoma in 1733. By historico-medically reexamining this case, we conclude that the brain concretions he described were not a case of frontal sinus osteoma, while they appear to have been pathological outcomes of neurocysticercosis, whose larval stages would only be described by Johann Goeze (1731-1793) later, in 1784. Thus, this case becomes relevant for the history of neuroparasitology. PMID- 29569098 TI - Strong and Weak Readings in the Domain of Worlds: A Negative Polar Modal and Children's Scope Assignment. AB - This study investigates children's interpretation of sentences with two logical operators: Dutch universal modal hoeven and negation (niet). In adult Dutch, hoeven is an NPI that necessarily scopes under negation, giving rise to a NOT > NECESSARY reading. The findings from a hidden-object task with 5- and 6-year-old children showed that children's performance is suggestive of an interpretation of sentences with hoeft niet in which the modal scopes over negation (NECESSARY > NOT). This is in line with the Semantic Subset Principle that dictates that children should opt for the strongest possible reading in case of potential scope ambiguities. The full pattern of results, however, seems to be determined, in addition, by a particular strategy children use when facing uncertainty called Premature Closure. PMID- 29569097 TI - Probing the antioxidant potential of phloretin and phlorizin through a computational investigation. AB - The structures and energetics of two dihydrochalcones (phloretin and its glycoside phlorizin) were examined with density functional theory, using the B3LYP, M06-2X, and LC-omega PBE functionals with both the 6-311G(d,p) and 6-311 + G(d,p) basis sets. Properties connected to antioxidant activity, i.e., bond dissociation enthalpies (BDEs) for OH groups and ionization potentials (IPs), were computed in a variety of environments including the gas-phase, n-hexane, ethanol, methanol, and water. The smallest BDEs among the four OH groups for phloretin (three for phlorizin) were determined (using B3LYP/6-311 + G(d,p) in water) to be 79.36 kcal/mol for phloretin and 79.98 kcal/mol for phlorizin while the IPs (at the same level of theory) were obtained as 139.48 and 138.98 kcal/mol, respectively. By comparing with known antioxidants, these values for the BDEs indicate both phloretin and phlorizin show promise for antioxidant activity. In addition, the presence of the sugar moiety has a moderate (0-6 kcal/mol depending on functional) effect on the BDEs for all OH groups. Interestingly, the BDEs suggest that (depending on the functional chosen) the sugar moiety can lead to an increase, decrease, or no change in the antioxidant activity. Therefore, further experimental tests are encouraged to understand the substituent effect on the BDEs for phloretin and to help determine the most appropriate functional to probe BDEs for dihydrochalcones. PMID- 29569099 TI - Transanal total mesorectal excision for rectal cancer: evaluation of the learning curve. AB - BACKGROUND: Transanal total mesorectal excision (TaTME) provides an excellent view of the resection margins for rectal cancer from below, but is challenging due to few anatomical landmarks. During implementation of this technique, patient safety and optimal outcomes need to be ensured. The aim of this study was to evaluate the learning curve of TaTME in patients with rectal cancer in order to optimize future training programs. METHODS: All consecutive patients after TaTME for rectal cancer between February 2012 and January 2017 were included in a single-center database. Influence of surgical experience on major postoperative complications, leakage rate and operating time was evaluated using cumulative sum charts and the splitting model. Correction for potential case-mix differences was performed. RESULTS: Over a period of 60 months, a total of 138 patients were included in this study. Adjusted for case-mix, improvement in postoperative outcomes was clearly seen after the first 40 patients, showing a decrease in major postoperative complications from 47.5 to 17.5% and leakage rate from 27.5 to 5%. Mean operating time (42 min) and conversion rate (from 10% to zero) was lower after transition to a two-team approach, but neither endpoint decreased with experience. Readmission and reoperation rates were not influenced by surgical experience. CONCLUSIONS: The learning curve of TaTME affected major (surgical) postoperative complications for the first 40 patients. A two-team approach decreased operative time and conversion rate. When implementing this new technique, a thorough teaching and supervisory program is recommended to shorten the learning curve and improve the clinical outcomes of the first patients. PMID- 29569100 TI - Acculturation and Unmet Health Needs Among Refugees in Omaha, Nebraska. AB - This study assessed the association between acculturation and unmet health needs among refugees. Based on data from the Refugee Health Needs Assessment Survey (n = 291) recently conducted in Omaha, Nebraska, Chi square tests and multivariate logistic regressions were estimated to examine how acculturation among refugees was related to their unmet health needs. Relative to refugees who had been in the U.S. for less than 3 years, refugees who had been in the U.S. for 3-5 years were more likely to report lack of health insurance coverage (AOR 2.87, 95% CI 1.19, 6.92) and delaying to see a health care provider due to cost during the 12 months prior to the survey (AOR 4.01, 95% CI 1.18, 13.67). Acculturation among refugees did not necessarily alleviate their unmet health needs. Addressing these needs calls for sustainable medical assistance to refugees that well go beyond the 8 month health insurance coverage currently provided to newly arrived refugees. PMID- 29569101 TI - Depressive and Anxiety Symptoms in Dutch Immigrant and Native Dialysis Patients. AB - Due to continuing migration there is more interest in the mental health status of immigrants. The aim of this study is to determine the prevalence of depressive/anxiety symptoms in immigrant and native dialysis patients, and to explore if patient characteristics can explain differences. The Beck depression inventory and the beck anxiety inventory were used. Differences between native and immigrant patients were explored using logistic regression models adjusted for patient characteristics. The prevalence of depressive symptoms was 35% for 245 native patients and 50% for 249 immigrant patients. The prevalence of anxiety symptoms was 35% for native patients and 50% for immigrant patients. In addition, the prevalence for co-morbid depressive and anxiety symptoms was 20% for native patients and 32% for immigrant patients. Crude ORs for depressive/anxiety symptoms for immigrant patients versus native patients were 1.8 (1.2-2.5) and 1.7 (1.2-2.5), respectively. After adjustment for patient characteristics ORs remained the same. Clinicians should be aware that immigrant dialysis patients are more prone to develop depressive and anxiety symptoms. Cultural factors might play a role and should therefore be assessed in future research. PMID- 29569102 TI - Acculturation and Adherence to Physical Activity Recommendations Among Chinese American and Non-Hispanic White Breast Cancer Survivors. AB - Chinese American breast cancer survivors' adherence to recommended physical activity (PA) guidelines has been understudied. This study investigated their PA adherence by acculturation level (vs. non-Hispanic White (NHW) survivors). One hundred ninety five Chinese and 202 NHW breast cancer survivors (stage 0-III) responded to a cross-sectional survey including a self-reported PA questionnaire. PA adherence referred to meeting PA recommendations for cancer survivors. Acculturation among Chinese was defined by proxies of U.S. residency, English proficiency, and interview language. Logistic regression was performed to examine factors associated with PA adherence. More-acculturated Chinese survivors' PA adherence rate was 76%. Less-acculturated Chinese survivors' adherence rate (60%) was significantly lower than that of NHWs (80%) (OR 0.38, 95%CI 0.19, 0.75). Less acculturated Chinese survivors were also less likely to engage in vigorous intensity PA than NHWs (p < 0.01). Future research on less-acculturated Chinese survivors' motivation for PA to promote their adherence is needed. PMID- 29569103 TI - Acute myeloid leukemia with translocation (1;21). AB - Advancement in genetic and molecular biology techniques has greatly helped our understanding of various diseases, especially hematological disorders. We describe a case of primary myelofibrosis (PMF) that transformed into acute myeloid leukemia with a very rare and unusual genetic translocation of (1;21). There are only five reported cases of this translocation in acute myeloid leukemia (AML) or myelodysplastic syndrome but none of them transformed from PMF. This case not only highlights the importance of rare genetic translocations but also provides the natural history of the disease and its poor prognosis. To the best of our knowledge our patient is the first reported case of AML transformed from PMF to have this unique translocation of (1;21). PMID- 29569105 TI - Bounding measures of genetic similarity and diversity using majorization. AB - The homozygosity and the frequency of the most frequent allele at a polymorphic genetic locus have a close mathematical relationship, so that each quantity places a tight constraint on the other. We use the theory of majorization to provide a simplified derivation of the bounds on homozygosity J in terms of the frequency M of the most frequent allele. The method not only enables simpler derivations of known bounds on J in terms of M, it also produces analogous bounds on entropy statistics for genetic diversity and on homozygosity-like statistics that range in their emphasis on the most frequent allele in relation to other alleles. We illustrate the constraints on the statistics using data from human populations. The approach suggests the potential of the majorization method as a tool for deriving inequalities that characterize mathematical relationships between statistics in population genetics.

PMID- 29569107 TI - Two new species of the Fusarium solani species complex isolated from compost and hibiscus (Hibiscus sp.). AB - Two new species in the Fusarium solani species complex (FSSC) are described and introduced. The new taxa are represented by German isolates CBS 142481 and CBS 142480 collected from commercial yard waste compost and vascular tissue of a wilting branch of hibiscus, respectively. The phylogenetic relationships of the collected strains to one another and within the FSSC were evaluated based on DNA sequences of 6 gene loci. Due to the limited sequence data available for reference strains in GenBank, however, a multi-gene phylogenetic analysis included partial sequences for the internal transcribed spacer region and intervening 5.8S nrRNA gene (ITS), translation elongation factor 1-alpha (tef1) and the RNA polymerase II second largest subunit (rpb2). Morphological and molecular phylogenetic data independently showed that these strains are distinct populations of the FSSC, nested within Clade 3. Thus, we introduce Fusarium stercicola and Fusarium witzenhausenense as novel species in the complex. In addition, 19 plant species of 7 legume genera were evaluated for their potential to host the newly described taxa. Eighteen plant species were successfully colonized, with 6 and 9 of these being symptomatic hosts for F. stercicola and F. witzenhausenense, respectively. As plants of the family Fabaceae are very distant to the originally sourced material from which the new taxa were recovered, our results suggest that F. stercicola and F. witzenhausenense are not host-specific and are ecologically fit to sustain stable populations in variety of habitats. PMID- 29569104 TI - Individualising Therapy to Minimize Bacterial Multidrug Resistance. AB - The scourge of antibiotic resistance threatens modern healthcare delivery. A contributing factor to this significant issue may be antibiotic dosing, whereby standard antibiotic regimens are unable to suppress the emergence of antibiotic resistance. This article aims to review the role of pharmacokinetic and pharmacodynamic (PK/PD) measures for optimising antibiotic therapy to minimise resistance emergence. It also seeks to describe the utility of combination antibiotic therapy for suppression of resistance and summarise the role of biomarkers in individualising antibiotic therapy. Scientific journals indexed in PubMed and Web of Science were searched to identify relevant articles and summarise existing evidence. Studies suggest that optimising antibiotic dosing to attain defined PK/PD ratios may limit the emergence of resistance. A maximum aminoglycoside concentration to minimum inhibitory concentration (MIC) ratio of > 20, a fluoroquinolone area under the concentration-time curve to MIC ratio of > 285 and a beta-lactam trough concentration of > 6 * MIC are likely required for resistance suppression. In vitro studies demonstrate a clear advantage for some antibiotic combinations. However, clinical evidence is limited, suggesting that the use of combination regimens should be assessed on an individual patient basis. Biomarkers, such as procalcitonin, may help to individualise and reduce the duration of antibiotic treatment, which may minimise antibiotic resistance emergence during therapy. Future studies should translate laboratory-based studies into clinical trials and validate the appropriate clinical PK/PD predictors required for resistance suppression in vivo. Other adjunct strategies, such as biomarker-guided therapy or the use of antibiotic combinations require further investigation. PMID- 29569108 TI - Rhodobacter sp. Rb3, an aerobic anoxygenic phototroph which thrives in the polyextreme ecosystem of the Salar de Huasco, in the Chilean Altiplano. AB - The Salar de Huasco is an evaporitic basin located in the Chilean Altiplano, which presents extreme environmental conditions for life, i.e. high altitude (3800 m.a.s.l.), negative water balance, a wide salinity range, high daily temperature changes and the occurrence of the highest registered solar radiation on the planet (> 1200 W m-2). This ecosystem is considered as a natural laboratory to understand different adaptations of microorganisms to extreme conditions. Rhodobacter, an anoxygenic aerobic phototrophic bacterial genus, represents one of the most abundant groups reported based on taxonomic diversity surveys in this ecosystem. The bacterial mat isolate Rhodobacter sp. strain Rb3 was used to study adaptation mechanisms to stress-inducing factors potentially explaining its success in a polyextreme ecosystem. We found that the Rhodobacter sp. Rb3 genome was characterized by a high abundance of genes involved in stress tolerance and adaptation strategies, among which DNA repair and oxidative stress were the most conspicuous. Moreover, many other molecular mechanisms associated with oxidative stress, photooxidation and antioxidants; DNA repair and protection; motility, chemotaxis and biofilm synthesis; osmotic stress, metal, metalloid and toxic anions resistance; antimicrobial resistance and multidrug pumps; sporulation; cold shock and heat shock stress; mobile genetic elements and toxin-antitoxin system were detected and identified as potential survival mechanism features in Rhodobacter sp. Rb3. In total, these results reveal a wide set of strategies used by the isolate to adapt and thrive under environmental stress conditions as a model of polyextreme environmental resistome. PMID- 29569109 TI - A novel pigmented and heavy metal biosorptive bacterium, Leucobacter epilobiisoli sp. nov., isolated from rhizosphere soil of Epilobium hirsutum L. AB - A novel yellow pigmented, Gram-positive, aerobic and heavy metal biosorptive bacterium designated SYP-B2667T was isolated from rhizosphere soil of Epilobium hirsutum L. in Tongren, Guizhou province, China. Based on 16S rRNA gene sequence analyses, it was shown that strain SYP-B2667T represents a novel species in the genus Leucobacter, with Leucobacter chromiireducens subsp. solipictus JCM 15573T as a close phylogenetic neighbour (sequence similarity of 98.2%). Chemotaxonomic characteristics also supported the affiliation to the genus Leucobacter. Strain SYP-B2667T was determined to have a DNA G+C content of 66.6 mol%; 2,4 diaminobutyric acid in the cell wall peptidoglycan amino acids; MK-11 as predominant menaquinone; an abundance of anteiso-C15:0 and anteiso-C17:0 fatty acids; and polar lipids including diphosphatidylglycerol, phosphatidylglycerol, glycolipids and unidentified phospholipids. The DNA-DNA hybridization value between strain SYP-B2667T and L. chromiireducens subsp. solipictus JCM 15573T was 19.7 +/- 2.8%. Based on these phylogenetic and phenotypic results, it can be concluded that strain SYP-B2667T represents a novel species, for which the name Leucobacter epilobiisoli sp. nov. is proposed. The type strain is SYP-B2667T (=DSM 105145T=CPCC 204976T). This strain can tolerate and adsorb five heavy metals and so may have potential to facilitate heavy metal removal and bioremediation. PMID- 29569110 TI - Comparison of Attitudes Toward Death Between University Students Who Receive Nursing Education and Who Receive Religious Education. AB - This study aims to compare attitudes toward death between university students who receive nursing education and who receive religious education. This study is cross-sectional in nature. It was conducted with the participation of 197 university students in a university located in the Eastern part of Turkey between June and August, 2017. Data were collected using the socio-demographic form and Turkish form of Death Attitudes Profile-Revised. Of all the students participating in the study, 52.8% received nursing education and 47.2% received religious education. It was found that majority of both groups had no education about death, or found the education they received insufficient. Besides, no significant differences were found between the students who received nursing education and who received religious education in terms of their attitudes toward death (p > 0.05). Results showed that students who received nursing education and who received religious education had similar attitudes toward death. In conclusion, the education given to students about the religious or health aspects of death in accordance with the curriculum seemed to have no effects on students' developing positive attitudes toward death. PMID- 29569111 TI - The Role of Healthcare Chaplains in Resuscitation: A Rapid Literature Review. AB - Spirituality is becoming of increasing importance in the international healthcare context. While patients' spirituality or faith is often overlooked, there is a growing awareness that understanding, addressing and supporting patients' spiritual and faith needs can influence healthcare outcomes. This review aims to illuminate this role and highlight healthcare chaplains' potential in relation to the provision of pastoral support for families during and after patient resuscitation, and the dearth of interdisciplinary education in this field. A rapid structured review was undertaken using four databases-PubMed, CINAHL, PsycINFO and ATLA. Primary research studies published during the 10-year period 2007-2017 written in English addressing the chaplain's role or perceived role in resuscitation were included. An initial search using key terms yielded 18 relevant citations. This reduced to 11 once duplicates were removed. Ultimately five relevant primary research studies were included in the final analysis. This review found few studies that directly explored the topic. Certainly many view the chaplain as a key member of the resuscitation team, although this role has not been fully explored. Chaplains likely have a key role in supporting families during decisions about 'not for resuscitation' and in supporting families during and after resuscitation procedures. Chaplains are key personnel, already employed in many healthcare organisations, who are in a pivotal position to contribute to future developments of spiritual and pastoral care provision and support. Their role at the end of life, despite well described and supported, has received little empirical support. There is an emerging role for chaplains in healthcare ethics, supporting end-of-life decisions and supporting family witnessed resuscitation where relevant. Their role needs to be more clearly understood by medical staff, and chaplain's input into undergraduate medical education programmes is becoming vital.

PMID- 29569114 TI - The Phox Homology (PX) Domain. AB - The phox-homology (PX) domain is a phosphoinositide-binding domain conserved in all eukaryotes and present in 49 human proteins. Proteins containing PX domains, many of which are also known as sorting nexins (SNXs), have a large variety of functions in membrane trafficking, cell signaling, and lipid metabolism in association with membranes of the secretory and endocytic system. In this review we discuss the structural basis for both canonical lipid interactions with the endosome-enriched lipid phosphatidylinositol-3-phosphate (PtdIns3P) as well as non-canonical lipids that promote membrane association. We also describe recent advances in defining the diverse mechanisms by which PX domains interact with other proteins including the retromer trafficking complex and proteins secreted by bacterial pathogens. Like other membrane interacting domains, the attachment of PX domain proteins to specific membranes is often facilitated by additional interactions that contribute to binding avidity, and we discuss this coincidence detection for several known examples. PMID- 29569112 TI - Phenylephrine increases cardiac output by raising cardiac preload in patients with anesthesia induced hypotension. AB - Induction of general anesthesia frequently induces arterial hypotension, which is often treated with a vasopressor, such as phenylephrine. As a pure alpha-agonist, phenylephrine is conventionally considered to solely induce arterial vasoconstriction and thus increase cardiac afterload but not cardiac preload. In specific circumstances, however, phenylephrine may also contribute to an increase in venous return and thus cardiac output (CO). The aim of this study is to describe the initial time course of the effects of phenylephrine on various hemodynamic variables and to evaluate the ability of advanced hemodynamic monitoring to quantify these changes through different hemodynamic variables. In 24 patients, after induction of anesthesia, during the period before surgical stimulus, phenylephrine 2 ug kg-1 was administered when the MAP dropped below 80% of the awake state baseline value for > 3 min. The mean arterial blood pressure (MAP), heart rate (HR), end-tidal CO2 (EtCO2), central venous pressure (CVP), stroke volume (SV), CO, pulse pressure variation (PPV), stroke volume variation (SVV) and systemic vascular resistance (SVR) were recorded continuously. The values at the moment before administration of phenylephrine and 5(T5) and 10(T10) min thereafter were compared. After phenylephrine, the mean(SD) MAP, SV, CO, CVP and EtCO2 increased by 34(13) mmHg, 11(9) mL, 1.02(0.74) L min-1, 3(2.6) mmHg and 4.0(1.6) mmHg at T5 respectively, while both dynamic preload variables decreased: PPV dropped from 20% at baseline to 9% at T5 and to 13% at T10 and SVV from 19 to 11 and 14%, respectively. Initially, the increase in MAP was perfectly aligned with the increase in SVR, until 150 s after the initial increase in MAP, when both curves started to dissociate. The dissociation of the evolution of MAP and SVR, together with the changes in PPV, CVP, EtCO2 and CO indicate that in patients with anesthesia-induced hypotension, phenylephrine increases the CO by virtue of an increase in cardiac preload. PMID- 29569116 TI - Longitudinal comparison of low- and high-velocity resistance training in relation to body composition and functional fitness of older adults. AB - BACKGROUND: Functional mobility disability affects more than one in five adults over 70 years and increases to 80% by 90 years. While negative changes in mobility are multifactorial, deleterious body composition changes contribute significantly. Resistance training alters the negative trajectory of physical function as well as increases lean mass among older adults. Recently, high velocity (HV) resistance training has been indicated as an effective intervention to increase lean mass and functional performance. AIMS: The present investigation compared body composition, physical function, and muscular strength changes between HV and LV resistance training programs. METHODS: Participants > 65 years (n = 53) were randomly assigned to LV, HV, or active control (AC) group and participated in their respective intervention for 48 weeks. RESULTS: Analysis of covariance revealed no significant body composition changes over time between groups (p > 0.05). Eight-foot up-and-go performance improved in the HV and AC groups (p < 0.05) with no change in the LV group (p > 0.05) over time. Muscular strength increased in both the LV and HV groups within the first 24 weeks, while only in the LV group, muscular strength continued to increase from 24 to 48 weeks (p < 0.05). DISCUSSION: Resistance training appears to be an effective intervention for improving aspects of physical function and muscular strength; however, no significant changes in body composition were observed over the 48 week intervention. CONCLUSION: Findings from the current investigation support use of resistance training for improving physical function among community dwelling older adults.

Particularly in the case of urothelial carcinoma, for the first time in 20 years, checkpoint inhibitors (PD-1 and PDL-1 inhibitors) provide well-tolerated therapy that achieves response rates of >20% that can be sustained over the long term. This review explains the approach of immunotherapy and summarizes the current phase III clinical situation on urothelial carcinoma and renal cell carcinoma. The current immunomodulatory therapeutic approaches for prostate cancer are discussed. Finally, we highlight new immunomodulatory therapeutic approaches in basic research. PMID- 29569117 TI - Twenty-year trends in cardiovascular risk among men and women in the United States. AB - BACKGROUND: Relative to men, women have experienced slower improvement in mortality in the US in recent decades. AIMS: We investigated 20-year trends in cardiovascular risk for men and women age 40 and over in the US to determine whether there was differential change in risk for men and women. METHODS: Using the National Health and Nutrition Examination Survey (NHANES), we estimated total cardiovascular risk, the prevalence of individual risk factors, and potential factors contributing to change in risk. RESULTS: Men showed steady reductions in cardiovascular risk over the 20 years; women experienced increased risk from 1990 to 2000, but decreased risk from 2000 to 2010. Sex differences in cardiovascular risk changed so that there was no significant difference by sex at any age over 50 in 2010. Large decreases in the prevalence of high risk lipids were important causes of reduction in risks for both sexes; changes in blood pressure were less important, except for women in the 2000-2010 period when they equaled the effect of changing lipids. Increasing medication usage and effectiveness drove improvements in blood pressure and total cholesterol for both sexes. In 2010 there was no difference between men and women in the use of antihypertensives or cholesterol-lowering medications. Metabolic risk, as indexed by obesity and HbA1c, increased over time and went against the trend in the summary measure. Diabetes, smoking, and hormone therapy use did not explain changes in high blood pressure or high total cholesterol for either gender. CONCLUSIONS: Recent decreases in cardiovascular risk may lead to future reduction in cardiovascular events and mortality among both women and men. PMID- 29569118 TI - Arterial stiffness and left ventricular performance in elderly patients with persistent atrial fibrillation. AB - BACKGROUND: The prevalence of atrial fibrillation (AF) and arterial stiffness (AS) increases with age. AIMS: To evaluate if AS is correlated to longitudinal strain (LS), a marker of left ventricular (LV) function, in elderly AF patients with preserved ejection fraction (EF) undergoing external cardioversion. METHODS: AS was measured using the cardio-ankle vascular index (CAVI), LS was calculated from echocardiographic data of three consecutive cardiac cycles. RESULTS: We enrolled 38 patients (age 76 +/- 8 years; men 60.5%; EF 65 +/- 7%). LS and CAVI were, respectively, - 17.7 +/- 3.7% and 9.7 +/- 1.3. Multivariate analysis showed that LV performance was inversely related to height (p < 0.001) and to the presence of AF-related symptoms (p = 0.008). LS grew with increasing values of CAVI (p = 0.038). CONCLUSIONS: In elderly AF patients with preserved systolic function, LV performance is directly associated with AS. This link could influence atrium remodeling and the incidence of arrhythmia relapse.

PMID- 29569121 TI - Identifying Clinically Relevant Proteins for Targeted Analysis in the Development of a Multiplexed Proteomic Biomarker Assay. AB - In recent years, hundreds of candidate protein biomarkers have been identified using discovery-based proteomics. Despite the large number of candidate biomarkers, few proteins advance to clinical validation. Here, we describe a hypothesis driven approach to identify candidate biomarkers, previously characterized in the literature, with the highest probability of clinical applicability. A ranking method, the hypothesis directed biomarker ranking (HDBR) system, was developed to score candidate biomarkers based on seven criteria deemed important in the selection of clinically useful biomarkers. The HDBR system was initially applied to identify candidate biomarkers for the development of a diagnostic test for the early detection of colorectal cancer, but this system can be widely applied to identify biomarkers of relevance in different disease states, for diagnosis, prognostication, or any other specific purpose. PMID- 29569120 TI - Early lymphocyte recovery predicts clinical outcome after HSCT with mycophenolate mofetil prophylaxis in the Japanese population. AB - Immune reconstitution affects clinical outcomes after allogeneic hematopoietic stem cell transplantation (HSCT), and it has been suggested that lymphocyte recovery affects survival after HSCT. However, few studies have examined lymphocyte recovery in Asian patients who received mycophenolate mofetil (MMF) prophylaxis for graft-versus-host disease. We retrospectively evaluated early lymphocyte recovery after HSCT among Japanese adults who received MMF prophylaxis. Patients were divided into two groups according to their median absolute lymphocyte count (ALC) on day 28 after HSCT as follows: the "low ALC group" (<= 0.22 * 109 cells/L) and the "high ALC group" (> 0.22 * 109 cells/L). With a median follow-up of 317 days, the high ALC group showed significantly better overall survival than the low ALC group (at 1 year: 62 vs. 46%, P = 0.02). The high ALC group also tended to have better non-relapse mortality than the low ALC group (at 1 year: 13 vs. 23%, P = 0.08). There was no significant difference in relapse rate between the high and low ALC groups (at 1 year: 29 vs. 35%, P = 0.2). We conclude that among Japanese patients who received MMF prophylaxis, ALC on day 28 after HSCT was effective in predicting overall survival and non-relapse mortality. PMID- 29569122 TI - Impact of maternal thyroid autoantibodies positivity on the risk of early term birth: Ma'anshan Birth Cohort Study. AB - PURPOSE: We aim to investigate associations of maternal serum anti thyroperoxidase autoantibody (TPOAb) with duration of gestation. We aim to investigate whether maternal TPOAb positivity is associated with the risk of premature or early term birth. METHODS: This was a prospective birth cohort study performed in an iodine sufficient area of China. Serum samples were collected from 2931 women at both the first and second trimesters of pregnancy. Thyrotropin (TSH), free thyroxine (FT4), and TPOAb levels were measured. Data on gestational age at birth was obtained from delivery records. RESULTS: The prevalence of early term birth was 23.8%, while the prevalence of premature birth was 4.2%. The prevalence of TPOAb positivity was 12.1% in the first trimester and was 7.2% in the second trimester. Gestational age at birth was inversely associated with lgTPOAb both in the first trimester (beta, -0.283, 95% CI -0.408, -0.158; P < 0.001) and in the second trimester (beta, -0.174, 95% CI -0.319, -0.030; P = 0.018), after adjustment for potential confounding factors. There was a positive association of TPOAb positivity with the risk of early term birth both in the first (OR = 1.691, 95% CI 1.302, 2.197) and second trimesters (OR = 1.644, 95% CI 1.193, 2.264), after adjustment for potential confounding factors. TPOAb positivity in the second trimester was associated with a 1.863-fold higher risk of premature birth (OR = 1.863, 95% CI 1.009, 3.441), after adjustment for potential confounding factors. CONCLUSIONS: Our results show that TPOAb is associated with shorter duration of gestation and with higher risk of premature and early term birth. PMID- 29569123 TI - Predictivity of clinical, laboratory and imaging findings in diagnostic definition of palpable thyroid nodules. A multicenter prospective study. AB - PURPOSE: To assess the role of clinical, biochemical, and morphological parameters, as added to cytology, for improving pre-surgical diagnosis of palpable thyroid nodules. METHODS: Patients with a palpable thyroid nodule were eligible if surgical intervention was indicated after a positive or suspicious for malignancy FNAC (TIR 4-5 according to the 2007 Italian SIAPEC-IAP classification), or two inconclusive FNAC at a >=3 months interval, or a negative FNAC associated with one or more risk factor. Reference standard was histological malignancy diagnosis. Likelihood ratios of malignancy, sensitivity, specificity, negative (NPV), and positive predictive value (PPV) were described. Multiple correspondence analysis (MCA) and logistic regression were applied. RESULTS: Cancer was found in 433/902 (48%) patients. Considering TIR4-5 only as positive cytology, specificity, and PPV were high (94 and 91%) but sensitivity and NPV were low (61 and 72%); conversely, including TIR3 among positive, sensitivity and NPV were higher (88 and 82%) while specificity and PPV decreased (52 and 63%). Ultrasonographic size >=3 cm was independently associated with benignity among TIR2 cases (OR of malignancy 0.37, 95% CI 0.18-0.78). In TIR3 cases the hard consistency of small nodules was associated with malignity (OR: 3.51, 95% CI 1.84 6.70, p < 0.001), while size alone, irrespective of consistency, was not diagnostically informative. No other significant association was found in TIR2 and TIR3. CONCLUSIONS: The combination of cytology with clinical and ultrasonographic parameters may improve diagnostic definition of palpable thyroid nodules. However, the need for innovative diagnostic tools is still high. PMID- 29569124 TI - Optimizing Amikacin Dosage in Pediatrics Based on Population Pharmacokinetic/Pharmacodynamic Modeling. AB - OBJECTIVE: Our objective was to determine the population pharmacokinetic parameters of amikacin in pediatric patients to contribute to the future development of a revised optimum dose and population-specific dosing regimens. METHODS: We performed a retrospective chart review in non-critical pediatric patients (aged 1-12 years) who received amikacin for suspected or proven Gram negative infection at a university hospital. The population pharmacokinetic models were developed using Monolix 4.4. Pharmacokinetic/pharmacodynamic (PK/PD) simulations were performed to explore the ability of different dosage regimens to achieve the pharmacodynamic targets. RESULTS: The analysis included 134 amikacin plasma concentrations from 67 patients with a mean +/- standard deviation age of 4.1 +/- 3.9 years and bodyweight of 15 +/- 8.4 kg. The patients received an amikacin total daily dose (TDD) of 23 +/- 7.3 mg/kg, which resulted in peak and trough concentrations of 20.65 +/- 7.6 and 2.4 +/- 1.7 mg/l, respectively. The estimated pharmacokinetic parameters for amikacin were 1.2 l/h and 6.5 l for total body clearance (CL) and the volume of distribution (V), respectively. Dosing simulations showed that the standard dosing regimen (15 mg/kg/day) of amikacin achieved the PK/PD target of peak serum concentration (Cpeak)/minimum inhibitory concentration (MIC) >= 8 for an MIC of 2 mg/l; higher doses were required to achieve higher MIC values. CONCLUSION: The simulation results indicated that amikacin 20 mg/kg once daily provided a higher probability of target attainment with lower toxicity than dosing three times daily. In addition, combination therapy is recommended for pathogens with an MIC of >= 8 mg/l. PMID- 29569125 TI - Preoperative Nomogram to Risk Stratify Patients for the Benefit of Trimodality Therapy in Esophageal Adenocarcinoma. AB - PURPOSE: To develop a nomogram that estimates 1-year recurrence-free survival (RFS) after trimodality therapy for esophageal adenocarcinoma and to assess the overall survival (OS) benefit of esophagectomy after chemoradiotherapy (CRT) on the basis of 1-year recurrence risk. METHODS: In total, 568 consecutive patients with potentially resectable esophageal adenocarcinoma who underwent CRT were included for analysis, including 373 patients who underwent esophagectomy after CRT (trimodality therapy), and 195 who did not undergo surgery (bimodality therapy). A nomogram for 1-year RFS was created using a Cox regression model. The upper tertile of the nomogram score was used to stratify patients in low-risk and high-risk groups for 1-year recurrence. The 5-year OS was compared between trimodality and bimodality therapy in low-risk and high-risk patients after propensity score matching, respectively. RESULTS: Median follow-up for the entire cohort was 62 months. The 5-year OS in the trimodality and bimodality treatment groups was 56.3% (95% confidence interval [CI] 47.9-64.7) and 36.9% (95% CI 31.4 42.4), respectively. The final nomogram for the prediction of 1-year RFS included male gender, poor histologic grade, signet ring cell adenocarcinoma, cN1, cN2-3, and baseline SUVmax, with accurate calibration and reasonable discrimination (C statistic: 0.66). Trimodality therapy was associated with improved 5-year OS in low-risk patients (p = 0.003), whereas it showed no significant survival benefit in high-risk patients (p = 0.302). CONCLUSIONS: The proposed nomogram estimates early recurrence risk. The addition of surgery to CRT provides a clear OS benefit in low-risk patients. The OS benefit of surgery in high-risk patients is less pronounced. PMID- 29569127 TI - Adjuvant Chemotherapy Versus Chemoradiotherapy Versus Surgery Alone for Early Gastric Cancer with One or Two Lymph Node Metastasis. AB - BACKGROUND: Limited studies exist comparing clinical outcomes by adjuvant treatment for pT1N1 gastric cancer. This study compared the disease-free survival (DFS) of patients with pT1N1 gastric cancer according to the type of adjuvant treatment-surgery alone, chemotherapy (CTx), and chemoradiotherapy (CCRTx)-and evaluated risk factors for tumor recurrence. METHODS: Between 1995 and 2015, 738 patients underwent radical gastrectomy for pT1N1 gastric cancer and were divided into three groups: surgery alone (n = 355), CTx (n = 214), and CCRTx (n = 169). Chronological changes in adjuvant treatment type and chemotherapeutic regimens were evaluated and DFS was compared. Risk factors for tumor recurrence were analyzed. RESULTS: The proportion of patients who underwent surgery alone was more than 50% until 2001, and the proportion of those who had either CTx or CCRTx was more than 50% from 2002 to 2011, after which the proportion who underwent surgery alone increased again. The main chemotherapeutic agent was 5-fluorouracil with leucovorin. The 5-year DFS was 96.5% in the surgery-alone group, 96.0% in the CTx group, and 95.8% in the CCRTx group (no significant difference). The various chemotherapeutic regimens did not show differences in DFS. In univariate and multivariate analyses, adjuvant CTx and CCRTx showed no beneficial effect with regard to tumor recurrence. CONCLUSIONS: Because adjuvant CTx and CCRTx did not show any benefit with regard to tumor recurrence, these treatment strategies might be unnecessary for pT1N1 gastric cancer after gastrectomy. Further studies are necessary to reveal pT1N1 gastric cancer patient subgroups who might benefit from adjuvant treatments. PMID- 29569126 TI - Palliative Care is Associated with Reduced Aggressive End-of-Life Care in Patients with Gastrointestinal Cancer. AB - BACKGROUND: We examined the delivery of physician palliative care (PC) services and its association with aggressive end-of-life care (EOLC) in patients with gastrointestinal (GI) cancer in Ontario, Canada. METHODS: All patients with primary cause of death from esophageal, gastric, colon, and anorectal cancer from January 2003 to December 2013 were identified. PC services within 2 years of death were classified: (1) any PC; (2) timing of first PC (<= 7, 8-90, 91-180, and 181-730 days before death); and (3) intensity of PC measured by number of days used (1st-25th, 26th-50th, 51st-75th, and 76th-100th percentiles). Aggressive EOLC was defined as any of the following: chemotherapy, emergency department visits, hospital or intensive care unit (ICU) admissions (all <= 30 days of death), and death in hospital and in the ICU; these were combined as a composite outcome (any aggressive EOLC). RESULTS: The cohort included 34,630 patients, of whom 74% had at least one PC service. Timing of the first PC service varied: <= 7 (12%), 8-90 (42%), 91-180 (16%), and 181-730 (30%) days before death. Compared with patients not receiving PC, any PC was associated with a reduction in any aggressive EOLC (risk ratio [RR] 0.75, 95% confidence interval [CI] 0.74-0.76); this association was similar regardless of timing of the first PC service. The most dramatic reduction in aggressive EOLC occurred in patients who received the greatest number of days of PC (RR 0.65, 95% CI 0.63-0.67). CONCLUSIONS: The majority of patients received PC within 2 years of death. A larger number of days of PC was associated with a greater reduction in aggressive EOLC. PMID- 29569128 TI - Letter to the Editor. PMID- 29569129 TI - Cytokine Responses in Severe Traumatic Brain Injury: Where There Is Smoke, Is There Fire? AB - This scoping review will discuss the basic functions and prognostic significance of the commonly researched cytokines implicated in severe traumatic brain injury (sTBI), including tumour necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL 1beta), IL-6, tissue inhibitor of matrix metalloproteinases-1 (TIMP-1), transforming growth factor-beta (TGF-beta), substance P, and soluble CD40 ligand (sCD40L). A scoping review was undertaken with an electronic search for articles from the Ovid MEDLINE, PUBMED and EMBASE databases from 1995 to 2017. Inclusion criteria were original research articles, and reviews including both animal models and human clinical studies of acute (< 3 months) sTBI. Selected articles included both isolated sTBI and sTBI with systemic injury. After applying the inclusion criteria and removing duplicates, 141 full-text articles, 126 original research articles and 15 review articles, were evaluated in compiling this review paper. A single reviewer, CC, completed the review in two phases. During the first phase, titles and abstracts of selected articles were reviewed for inclusion. A second evaluation was then conducted on the full text of all selected articles to ensure relevancy. From our current understanding of the literature, it is unlikely a single biomarker will be sufficient in accurately prognosticating patients with sTBI. Intuitively, a more severe injury will demonstrate higher levels of inflammatory cytokines which may correlate as a marker of severe injury. This does not mean, necessarily, these cytokines have a direct and causal role in the poor outcome of the patient. Further research is required to better delineate the complex systemic inflammatory and CNS interactions that occur during sTBI before they can be applied as a reliable prognostic tool. PMID- 29569130 TI - Correlation of Noninvasive Blood Pressure and Invasive Intra-arterial Blood Pressure in Patients Treated with Vasoactive Medications in a Neurocritical Care Unit. AB - BACKGROUND: The correlation between noninvasive (oscillometric) blood pressure (NBP) and intra-arterial blood pressure (IAP) in critically ill patients receiving vasoactive medications in a Neurocritical Care Unit has not been systematically studied. The purpose of this study is to examine the relationship between simultaneously measured NBP and IAP recordings in these patients. METHODS: Prospective observational study of patients (N = 70) admitted to a neurocritical care unit receiving continuous vasopressor or antihypertensive infusions. Paired NBP/IAP observations along with covariate and demographic data were abstracted via chart audit. Analysis was performed using SAS v9.4. RESULTS: A total of 2177 paired NBP/IAP observations from 70 subjects (49% male, 63% white, mean age 59 years) receiving vasopressors (n = 21) or antihypertensive agents (n = 49) were collected. Paired t test analysis showed significant differences between NBP versus IAP readings: ([systolic blood pressure (SBP): mean = 136 vs. 140 mmHg; p < 0.0001], [diastolic blood pressure (DBP): mean = 70 vs. 68 mmHg, p < 0.0001], [mean arterial blood pressure (MAP): mean = 86 vs. 90 mmHg, p < 0.0001]). Bland-Altman plots for MAP, SBP, and DBP demonstrate good inter-method agreement between paired measures (excluding outliers) and demonstrate NBP-IAP SBP differences at extremes of blood pressures. Pearson correlation coefficients show strong positive correlations for paired MAP (r = 0.82), SBP (r = 0.84), and DBP (r = 0.73) recordings. An absolute NBP-IAP SBP difference of > 20 mmHg was seen in ~ 20% of observations of nicardipine, ~ 25% of observations of norepinephrine, and ~ 35% of observations of phenylephrine. For MAP, the corresponding numbers were ~ 10, 15, and 25% for nicardipine, norepinephrine, and phenylephrine, respectively. CONCLUSION: Despite overall strong positive correlations between paired NBP and IAP readings of MAP and SBP, clinically relevant differences in blood pressure are frequent. When treating with vasoactive infusions targeted to a specific BP goal, it is important to keep in mind that NBP and IAP values are not interchangeable. PMID- 29569131 TI - Acquired spondylolysis and spinopelvic sagittal alignment. AB - Acquired spondylolysis represents an uncommon complication of spine surgery, of an unknown incidence and etiology. We studied patients presenting this rare entity, with the purpose to investigate the incidence, imaging findings, patients' clinical characteristics, as well as to provide an interpretation of the mechanisms that may lead to this phenomenon. The presented working hypothesis, regarding etiology, suggests that there is a relation between variations in spinopelvic sagittal alignment and acquired spondylolysis. Between January 2010 and January 2015, six patients presented spondylolysis after short segment transforaminal lumbar interbody fusion, at a mean time of 43 months after surgery. The preoperative intactness and postoperative defect of pars interarticularis were documented with computed tomography scans in all patients. Standard radiographical spinopelvic parameters were measured before and after surgery. The optimum values of lumbar lordosis (LL) and pelvic incidence minus lumbar lordosis modifier (PI-LL mismatch) were calculated as well. The incidence of acquired spondylolysis was 0.95% among patients with short-segment lumbar fusion. Patients presented high-grade PI with a vertically orientated sacral endplate, while LL was found 9 degrees greater and PI-LL mismatch 9 degrees lower than the respective optimum values, indicating a non-harmonized alignment. In conclusion, acquired spondylolysis, though rare, may occur in patients with high-grade PI and sacral slope, and suboptimal spinopelvic sagittal alignment after lumbar spine surgery, thereby highlighting the importance of detailed preoperative planning in spine surgery, along with the study of sagittal balance.

PMID- 29569132 TI - Fixation method for treatment of unstable distal clavicle fracture: systematic review and network meta-analysis. AB - Surgical management is recommended for unstable distal clavicle fractures. A variety of methods have been previously reported, but there is no current consensus regarding which method is most suitable. Therefore, we have conducted a systematic review and network meta-analysis to compare postoperative shoulder function and complications between different fixation methods to identify which class of fixation is best for unstable distal clavicle fractures. We searched the literature systematically using eligibility criteria of all comparative studies that compared postoperative outcomes of coracoclavicular fixation (tight rope, screw or endobutton), hook plating, plate and screws, tension band wiring and transacromial pinning fixation for unstable distal clavicle fractures from PubMed, EMBASE, and Scopus databases up to February 10, 2018. Two reviewers independently extracted data. A network meta-analysis was applied to combine direct and indirect evidence and to estimate the relative effects of the treatment options. The probability of being the best treatment was estimated using surface under the cumulative ranking curves (SUCRA). Ten comparative studies (n = 505 patients) with one RCT study (n = 42) met the inclusion criteria. Intervention included coracoclavicular fixation (n = 111 patients), hook plating (n = 300 patients), plate and screws (n = 41 patients), tension band wiring (n = 81 patients) and transacromial pinning (n = 14 patients). A network meta-analysis showed that CM scores of coracoclavicular fixation were significantly higher when compared to hook plate and tension band wiring, with pooled mean of 2.98 (95% CI 0.05-5.91) and 7.11 (95% CI 3.04-11.18). For UCLA, CC fixation and plate and screw fixation had significantly higher scores compared to hook plating fixation with a mean score 2.22 (95% CI 0.44-3.99) and 3.20 (95% CI 0.28-6.12), respectively. In terms of complications, plate and screw fixation had lower risk with RRs of 0.63 (95% CI 0.20-1.98), 0.37 (95% CI 0.19-0.72), 0.11 (95% CI 0.04-0.30) and 0.02 (95% CI 0.002-0.16) when compared to coracoclavicular fixation, hook plating, tension band wiring and transacromial pinning. The SUCRA probabilities of CC fixation were in the first rank with 96.8% for CMS, while plate and screw fixation were in the first rank with 67.7 and 93.8% for UCLA score and complications. We recommend using plate and screw and CC fixation as the first- and second-line treatment of unstable distal clavicle fractures. As the quality of studies for this meta-analysis was not high, larger and higher quality randomized controlled trials are required to confirm these conclusions for informed clinical decision making. PMID- 29569134 TI - The microbiology of chronic rhinosinusitis with and without nasal polyps. AB - OBJECTIVE: To compare the microbiological features in middle meatus samples from chronic rhinosinusitis (CRS) patients with nasal polyps (CRSwNP) and those without nasal polyps (CRSsNP), and control subjects. METHODS: A total of 136 CRSwNP patients, 66 CRSsNP patients, and 49 control subjects who underwent endoscopic surgery in Beijing TongRen Hospital were enrolled between January 2014 and January 2016. Swab samples were obtained from the middle meatus during surgery and processed for the presence of aerobic and non-aerobic bacteria and fungi. Information on the allergic rhinitis, asthma, the percentage of eosinophils in peripheral blood, and the history of smoking and surgery was collected. RESULTS: The overall isolation rate for bacteria was 81.3% for the three groups, with the lowest in the CRSsNP group (77.3%) and the highest in the CRSwNP group (88.4%). There were no significant differences in isolation rates among the three groups (P = 0.349). The three most common bacterial species were: Coagulase-negative Staphylococcus (24.3%), Corynebacterium (19.9%), and Staphylococcus epidermidis (19.1%) in the CRSwNP group; S. epidermidis (21.2%), Corynebacterium (21.2%), Coagulase-negative staphylococcus (18.2%), and Staphylococcus aureus (13.6%) in the CRSsNP group; S. epidermidis (30.6%), Coagulase-negative Staphylococcus (28.6%), and S. aureus (14.3%) in the control group. For the bacterial species with high isolation rates, no significant difference in the microbial cultures was observed among the three groups; whereas in the CRSwNP group, a relatively high proportion of Citrobacter (5.9%, a bacterium with low isolation rate) was observed compared with the CRSsNP and control groups (all 0.0%). Furthermore, when samples were categorized into subgroups according to the percentage of eosinophils, some bacterial species showed different rates in the CRSwNP group (e.g., S. aureus, 3.3% in the subgroup with normal percentage of eosinophils, 17.2% in the subgroup with increased percentage of eosinophils, P = 0.011). CONCLUSIONS: There were no significant differences in the microbiological features (except Citrobacter) in middle meatus samples from CRSwNP patients, CRSsNP patients, and control subjects. S. aureus may promote eosinophilic inflammatory response, while S. epidermidis may promote non-eosinophilic inflammatory response. PMID- 29569135 TI - Malnutrition and refeeding syndrome prevention in head and neck cancer patients: from theory to clinical application. AB - PURPOSE: The goal of this review is to raise awareness about refeeding syndrome (RFS) and to give a comprehensive presentation of recent guidelines and latest scientific data about nutritional management among head and neck cancer (HNC) patients while focusing on RFS prevention. METHODS: A review of literature for nutritional assessment and RFS management was conducted. Electronic searches of Medline, Cochrane, PubMed and Embase databases for articles published in peer reviewed journals were conducted from February to September 2017 using the keywords: "nutrition assessment", "head and neck cancer", "refeeding syndrome" and "guidelines". Articles, reviews, book references as well as national and international guidelines in English and French were included. RESULTS: The prevalence of malnutrition is high in HNC patients and a large number of them will need artificial nutritional support or refeeding intervention. RFS is characterized by fluid and electrolyte imbalance associated with clinical manifestations induced by rapid refeeding after a period of malnutrition or starvation. Regarding risk factors for malnutrition and RFS, HNC patients are particularly vulnerable. However, RFS remains unrecognized among head and neck surgeons and medical teams. Practical data are summarized to help organizing nutritional assessment and refeeding interventions. It also summarizes preventive measures to reduce RFS incidence and morbidity in HNC population. CONCLUSION: Nutritional assessment and early refeeding interventions are crucial for HNC patients care. As prevention is the key for RFS management, early identification of patients with high risks is crucial and successful nutritional management requires a multidisciplinary approach. PMID- 29569136 TI - How to clarify the aims of empathy in medicine. AB - This paper argues that enthusiasm for empathy has grown to the point at which empathy has taken on the status of an "ideal" in modern medicine. We need to pause and scrutinize this ideal before moving forward with empathy training programs for medical students. Taking empathy as an ideal obscures the distinction between the multiple aims that calls for empathy seek to achieve. While these aims may work together, they also come apart and yield different recommendations about the sort of behavior physicians should cultivate in a given situation. I begin by demonstrating how enthusiasm for empathy has increased dramatically. I then specify precisely what I mean in calling empathy an "ideal." I then describe some dangers associated with taking empathy to be an ideal unreflectively. I discuss the merits of works that provide conceptualizations of empathy that are specifically tailored for the medical domain and conclude that although these works move discussions about empathy in medical care forward, they could do more to foreground the goals and aims underlying calls for increased empathy. I provide specific suggestions as to how exactly we might foreground these goals and aims to further avoid conceptual confusion about empathy in medical education.

AB - PURPOSE: Proximal tibia replacements are commonly associated with post-operative complications and poor functional results due to an insufficiency of the extensor mechanism. METHODS: This study evaluated the clinical results with a special emphasis of the extensor mechanism reconstruction with a reattachment tube and complications after intra-articular resection of the proximal tibia and reconstruction with a tumour endoprosthesis (MUTARS(r)) in 98 patients (median age 18 years) with malignant bone tumours or giant cell tumours. RESULTS: Kaplan Meier analysis showed that the limb survival rates were 94.9, 90.5 and 74.5% at one, two and ten years, respectively. Periprosthetic infection was the most common reason for secondary amputation (eight patients). The cumulative incidence rates of prosthetic failure (Henderson II-IV) were 18% at two years and 29% at five years post-operatively. An active extension deficit of more than 10 degrees was noted in six patients only. CONCLUSIONS: These results suggest that limb salvage with tumour prostheses after intra-articular resection can achieve good functional results with an active extension of the knee in the majority of patients. While mechanical complications can be treated successfully with revision surgery, periprosthetic infection continues to be the main reason for secondary amputation. PMID- 29569139 TI - Bone-preserving total hip arthroplasty in avascular necrosis of the hip-a matched pairs analysis. AB - PURPOSE: Short-stem hip arthroplasty has the potential advantage of femoral bone stock preservation, especially in view of the expected revisions in the often relatively young patients. Despite short-stem hip prosthesis are increasingly used for total hip arthroplasty, there are no sufficient mid- and long-term results especially for patients with avascular femoral head osteonecrosis. The present study investigates mid-term functional results as well as the revision rate following implantation of a short-stem prosthesis. METHODS: In the period 06/2005 until 12/2013, a total of 351 short-stem hip prostheses were implanted. The study included 331 complete data sets. A retrospective analysis was performed using the Oxford Hip Score. All revisions were registered. RESULTS: In a total of 331 prostheses, the Oxford Hip Score was "excellent" in 66.2%, "good" in 12.7%, "fair" in 13.0%, and "poor" in 8.2% with a mean follow-up of 57.4 months (SD +/- 29.8; range 24-115). In 26 cases, aseptic osteonecrosis of the hip was the indication (7.9%). The Oxford Hip Score was "excellent" in 66.7%, "good" in 0.0%, "fair" in 20.8%, and "poor" in 12.5%. The cumulated five year survival rate was 96.7%. CONCLUSION: In mid-term observation, the Metha(r) short-stem prosthesis shows no disadvantage in functional outcome and in survival time compared to a standard hip stem. Providing a correct indication, the Metha(r) short stem is a valuable option in total hip arthroplasty for younger patients with avascular osteonecrosis of the femoral head. Evaluation has shown no significant differences between aseptic osteonecrosis and other indications. PMID- 29569140 TI - Mobile-bearing unicompartmental knee arthroplasty in old-aged patients demonstrates superior short-term clinical outcomes to open-wedge high tibial osteotomy in middle-aged patients with advanced isolated medial osteoarthritis. AB - PURPOSE: The aim of the present study was to compare the clinical outcomes of mobile-bearing unicompartmental knee arthroplasty (MB-UKA) and open-wedge high tibial osteotomy (OWHTO) for advanced isolated medial osteoarthritis (OA). METHODS: Patients with advanced medial compartment OA (Ahlback grade >= II) who underwent either MB-UKA with Oxford Knee or OWHTO were included. The minimum follow-up was two years. Clinical outcomes were evaluated using the Hospital for Special Surgery (HSS) score, knee score (KS), and function score (FS) of the Knee Society Knee Scoring System. Pre-operative and post-operative values were compared within groups. Pre-operative and post-operative values and the degree of change were compared between the two groups. Radiologic progression of OA in either the lateral or patellofemoral compartment was evaluated. RESULTS: Forty knees (20 received MB-UKA, 20 received OWHTO) were enrolled. The mean age was higher in the MB-UKA group (67.9 +/- 9.0 years) than in the OWHTO group (58.4 +/- 5.5 years). The HSS score, KS, and FS were significantly increased post operatively in both groups. The preoperative HSS score, KS, and FS were significantly lower in the MB-UKA than in the OWHTO group; however, only the post operative HSS score was significantly higher in the MB-UKA group. The changes in HSS score and KS were also greater in the MB-UKA group. There was no significant difference in OA progression. CONCLUSIONS: Although there was an age difference between the two groups, MB-UKA demonstrated superior short-term clinical outcomes to OWHTO for advanced isolated medial OA. In particular, MB-UKA was more effective in terms of pain relief. PMID- 29569141 TI - A simple and widely available alternative method for endotracheal tube cuff pressure monitoring. PMID- 29569142 TI - Sample size calculations for randomized clinical trials published in anesthesiology journals: a comparison of 2010 versus 2016. AB - PURPOSE: Although every randomized clinical trial (RCT) needs participants, determining the ideal number of participants that balances limited resources and the ability to detect a real effect is difficult. Focussing on two-arm, parallel group, superiority RCTs published in six general anesthesiology journals, the objective of this study was to compare the quality of sample size calculations for RCTs published in 2010 vs 2016. METHODS: Each RCT's full text was searched for the presence of a sample size calculation, and the assumptions made by the investigators were compared with the actual values observed in the results. Analyses were only performed for sample size calculations that were amenable to replication, defined as using a clearly identified outcome that was continuous or binary in a standard sample size calculation procedure. RESULTS: The percentage of RCTs reporting all sample size calculation assumptions increased from 51% in 2010 to 84% in 2016. The difference between the values observed in the study and the expected values used for the sample size calculation for most RCTs was usually > 10% of the expected value, with negligible improvement from 2010 to 2016. CONCLUSION: While the reporting of sample size calculations improved from 2010 to 2016, the expected values in these sample size calculations often assumed effect sizes larger than those actually observed in the study. Since overly optimistic assumptions may systematically lead to underpowered RCTs, improvements in how to calculate and report sample sizes in anesthesiology research are needed.

AB - Culturally relevant health promotion is an opportunity to reduce health inequities in diseases with modifiable risks, such as cancer. Alaska Native people bear a disproportionate cancer burden, and Alaska's rural tribal health workers consequently requested cancer education accessible online. In response, the Alaska Native Tribal Health Consortium cancer education team sought to create a framework for culturally relevant online learning to inform the creation of distance-delivered cancer education. Guided by the principles of community-based participatory action research and grounded in empowerment theory, the project team conducted a focus group with 10 Alaska Native education experts, 12 culturally diverse key informant interviews, a key stakeholder survey of 62 Alaska Native tribal health workers and their instructors/supervisors, and a literature review on distance-delivered education with Alaska Native or American Indian people. Qualitative findings were analyzed in Atlas.ti, with common themes presented in this article as a framework for culturally relevant online education. This proposed framework includes four principles: collaborative development, interactive content delivery, contextualizing learning, and creating connection. As an Alaskan tribal health worker shared "we're all in this together. All about conversations, relationships. Always learn from you/with you, together what we know and understand from the center of our experience, our ways of knowing, being, caring." The proposed framework has been applied to support cancer education and promote cancer control with Alaska Native people and has motivated health behavior change to reduce cancer risk. This framework may be adaptable to other populations to guide effective and culturally relevant online interventions. PMID- 29569144 TI - A Highly Pathogenic Strain of Porcine Deltacoronavirus Caused Watery Diarrhea in Newborn Piglets. AB - Porcine deltacoronavirus (PDCoV) is a newly identified virus that causes watery diarrhea in newborn piglets and results in significant economic losses to the pig industry. Since first reported in Hong Kong in 2012, PDCoV has been subsequently detected in USA, South Korea, Thailand, and mainland China. Here we isolated a strain of PDCoV, named CHN-GD-2016, from the intestinal content of a diseased newborn piglet with severe diarrhea in a pig farm in Guangdong, China. PDCoV CHN GD-2016 could be identified by immunofluorescence with PDCoV specific rabbit antisera, and typical crown-shaped particles with spiky surface projections of this PDCoV were observed with electron microscopy. Genomic analysis showed that the PDCoV CHN-GD-2016 was closely related to other Chinese PDCoV strains, with the highest sequence similarity with the strain CHN/Tianjin/2016. Importantly, inoculation of newborn piglets with 1 * 105 TCID50 of CHN-GD-2016 by oral feeding successfully reproduced clear clinical symptoms, including vomiting, dehydration, and severe diarrhea in piglets. In addition, the virus RNA in rectal swabs from 1 to 7 days post inoculation was detected, macroscopic and microscopic lesions in small intestine were observed, and viral antigen was also detected in the small intestines with immunohistochemical staining. Collectively, the data show in this study confirms that PDCoV is present in Guangdong, China and is highly pathogenic in newborn piglets.

PMID- 29569146 TI - Anticoagulation in atrial fibrillation with heart failure. AB - Heart failure (HF) and atrial fibrillation (AF) frequently coexist, and they can beget one another due to similar factors and shared pathophysiology. These pathophysiologic changes promote the episodes of AF, while they in turn predispose to the exacerbation of HF. In this review, we will discuss pathophysiological mechanisms shared by AF and HF. Patients with concomitant HF and AF are at a particularly high risk of thromboembolism, which contribute to even worse symptoms and poorer prognosis. Vitamin K antagonists (VKA) (warfarin) were the traditional medication in AF patients for the prevention of stroke, whereas the advance of novel non-VKA oral anticoagulants (NOACs) (dabigatran, apixaban, rivaroxaban, and edoxaban) is challenging these standard prescriptions. NOACs' potential advantages over warfarin, including fixed dosing regimens, wide therapeutic window, and more sustained anticoagulant response, promote clinicians to consider these novel agents in the first place. However, some data suggested patients with AF and HF may receive different therapeutic response than those with AF alone in anticoagulant treatment. Accordingly, we aim to assess the potential role of oral anticoagulants, especially NOACs, in the management of patients with concomitant AF and HF. PMID- 29569147 TI - Hypertension and its severity in children with steroid sensitive nephrotic syndrome during remission. AB - BACKGROUND AND OBJECTIVE: Hypertension is not a typical feature of steroid sensitive nephrotic syndrome (SSNS) and the presence of persistent hypertension is suggestive of significant renal lesion. There is paucity of data regarding occurrence and severity of hypertension in SSNS in pediatric population during remission and was the main objective of this study. In addition, correlation with factors like family history, BMI, and lipid profile was studied. METHODS: Cross sectional study conducted at tertiary care center in India including 81 children of infrequent relapsing SSNS between 1 and 10 years in remission and was off steroids. Grading and severity of hypertension were assessed. Statistical analysis was done using SPSS version 21.0. RESULTS: Median age of presentation was 5 years, with male:female ratio of 1.3:1. Out of 81 infrequent relapsing SSNS children, 23.45% (19) had hypertension. Among those children with hypertension (n = 19), 73.68% (14) had positive family history compared to 32.25% (20) in those without hypertension. Positive correlation was found between BP and serum cholesterol and LDL. Of the hypertensive patients, 1 (5.26%) had fundus changes, 2 (10.52%) had features of left ventricular hypertrophy, and 13 (68.42%) had non nephrotic range proteinuria. CONCLUSION: There is high incidence of hypertension in NS children during remission. Though significant positive correlation was found with positive family history of hypertension and deranged lipid profile highlighting possibility of essential hypertension in them, there is need for close active monitoring and management of hypertension in them as untreated cases may have significant target organ damage. PMID- 29569148 TI - [Lipid-lowering therapy in the elderly : Who profits from which target values?] AB - Lowering low-density lipoprotein (LDL) cholesterol levels has been proven to reduce the incidence of cardiovascular and cerebrovascular events and mortality. So far recommendations have not provided information as to a meaningful duration of cholesterol-lowering therapy and were largely guided by economic constraints and limited therapeutic options. In light of the decline in the price of statins, the essential therapeutic agent and the increased efficacy of therapeutic options, treatment can nowadays be geared to target values that can be expected to have an optimal effect even in old age. The most favorable level of LDL cholesterol for primary prevention is around and below 100 mg/dl, provided continuous adherence to these low levels from adolescence onwards. With later onset of cholesterol reduction the existence of initial atheromatous deposits must be expected. Therefore, with age and the manifestation of other risk factors the optimal treatment targets increasingly converge to those for which experience has been gained from secondary prevention. Both measurements of the effect of cholesterol lowering on the volume of atheromatous plaques and of the incidence of vascular events indicate a target for LDL-cholesterol well below 70 mg/dl and in the range 50-60 mg/dl. At the onset of cholesterol lowering in advanced age, a smaller effect has to be expected but due to the increasing incidence rate of vascular events a higher number of events may be avoided; thus, the efficiency does not necessarily decrease; however, long-term studies indicate that earlier cholesterol lowering provides an advantage for more than a decade, in terms of preventing vascular disease, which tends to increase. Therefore, optimal cardiovascular prevention involves moderate measures to maintain the LDL cholesterol below 100 mg/dl lifelong from childhood on. PMID- 29569149 TI - [Aortic diseases : Modern diagnostic and therapeutic strategies]. AB - Aortic diseases include not only the thoracic but also the abdominal part of the aorta. In the etiology cardiovascular risk factors, such as hypertension, smoking and hyperlipoproteinemia play a major role, but more and more genetic diseases with familiar predisposition are being identified. Even large aneurysms remain asymptomatic as long as other organs in the neighborhood are not damaged and no acute aortic event occurs including aortic dissection, intramural hematoma, penetrating aortic ulcer, and traumatic aortic injury. Standardized algorithms allow precise and rapid diagnosis for initiating medicinal therapy or operative and/or endovascular interventions (thoracic/endovascular aortic repair, TEVAR/EVAR) in this emergency situation. Specialized aortic centers are recommended to form localized regional networks. PMID- 29569150 TI - Impaired lipid metabolism markers to assess the risk of neuroinflammation in autism spectrum disorder. AB - Autism spectrum disorder (ASD) is a multifactorial disorder caused by an interaction between environmental risk factors and a genetic background. It is characterized by impairment in communication, social interaction, repetitive behavior, and sensory processing. The etiology of ASD is still not fully understood, and the role of neuroinflammation in autism behaviors needs to be further investigated. The aim of the present study was to test the possible association between prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2), microsomal prostaglandin E synthase-1 (mPGES-1), prostaglandin PGE2 EP2 receptors and nuclear kappa B (NF-kappaB) and the severity of cognitive disorders, social impairment, and sensory dysfunction. PGE2, COX-2, mPGES-1, PGE2-EP2 receptors and NF-kappaB as biochemical parameters related to neuroinflammation were determined in the plasma of 47 Saudi male patients with ASD, categorized as mild to moderate and severe as indicated by the Childhood Autism Rating Scale (CARS) or the Social Responsiveness Scale (SRS) or the Short Sensory Profile (SSP) and compared to 46 neurotypical controls. The data indicated that ASD patients have remarkably higher levels of the measured parameters compared to neurotypical controls, except for EP2 receptors that showed an opposite trend. While the measured parameter did not correlate with the severity of social and cognitive dysfunction, PGE2, COX-2, and mPGES-1 were remarkably associated with the dysfunction in sensory processing. NF-kappaB was significantly increased in relation to age. Based on the discussed data, the positive correlation between PGE2, COX-2, and mPGES-1 confirm the role of PGE2 pathway and neuroinflammation in the etiology of ASD, and the possibility of using PGE2, COX-2 and mPGES-1 as biomarkers of autism severity. NF-kappaB as inflammatory inducer showed an elevated level in plasma of ASD individuals. Receiver operating characteristic analysis together with predictiveness diagrams proved that the measured parameters could be used as predictive biomarkers of biochemical correlates to ASD. PMID- 29569151 TI - Mass scaling of the resting and maximum metabolic rates of the black carp. AB - We investigated the body mass (M) scaling of resting metabolic rate (RMR), maximum metabolic rate (MMR), excess post-exercise oxygen consumption (EPOC), blood parameters, and organ masses of black carp (Mylopharyngoden piceus). The results showed that RMR scaled with M of the fish by an exponent (b) of 0.833 (bR), which was significantly larger than 0.75. MMR scaled with M by a power of 0.775 (bM), which was significantly lower than 1 and may be due to a small size proportion of red muscle. No difference between bR and bM or correlation between factorial aerobic scope and M was found. However, EPOC scaled positively with M by a power of 1.231, suggesting a constant aerobic capacity and an enhanced anaerobic capacity with fish growth. Mass of the inactive organs scaled with M by a power of 1.005, which was significantly larger than 1 and was negatively correlated with RMR, suggesting that the proportion of inactive organs increases with fish growth, which may contribute to the negative scaling of RMR. Red blood cell surface area (S) did not increase with increasing M, suggesting that the ontogenetic decrease in the surface area to volume ratio of cells may not contribute to the negative scaling of RMR. The predicted bR value (0.846) by the average S (1.746 um2) differs by only 1.62% from the observed bR value using our previously reported S - bR function in carp, suggesting that the species-specific cell size, rather than its ontogenetic change, affects the metabolic scaling of a species. PMID- 29569152 TI - Predicting mortality and incident immobility in older Belgian men by characteristics related to sarcopenia and frailty. AB - : There is an increasing awareness of sarcopenia in older people. We applied machine learning principles to predict mortality and incident immobility in older Belgian men through sarcopenia and frailty characteristics. Mortality could be predicted with good accuracy. Serum 25-hydroxyvitamin D and bone mineral density scores were the most important predictors. INTRODUCTION: Machine learning principles were used to predict 5-year mortality and 3-year incident severe immobility in a population of older men by frailty and sarcopenia characteristics. METHODS: Using prospective data from 1997 on 264 older Belgian men (n = 152 predictors), 29 statistical models were developed and tuned on 75% of data points then validated on the remaining 25%. The model with the highest test area under the curve (AUC) was chosen as the best. From these, ranked predictor importance was extracted. RESULTS: Five-year mortality could be predicted with good accuracy (test AUC of .85 [.73; .97], sensitivity 78%, specificity 89% at a probability cut-off of 22.3%) using a Bayesian generalized linear model. Three-year incident severe immobility could be predicted with fair accuracy (test AUC .74 [.57; .91], sensitivity 67%, specificity 78% at a probability cut-off of 14.2%) using a multivariate adaptive regression splines model. Serum 25-hydroxyvitamin D levels and hip bone mineral density scores were the most important predictors of mortality, while biochemical androgen markers and Short-Form 36 Physical Domain questions were the most important predictors of immobility. Sarcopenia assessed by lean mass estimates was relevant to mortality prediction but not immobility prediction. CONCLUSIONS: Using advanced statistical models and a machine learning approach 5-year mortality can be predicted with good accuracy using a Bayesian generalized linear model and 3-year incident severe immobility with fair accuracy using a multivariate adaptive regression splines model.

PMID- 29569154 TI - Variations in Endosymbiont Infection Between Buprofezin-Resistant and Susceptible Strains of Laodelphax striatellus (Fallen). AB - The endosymbionts Wolbachia and Rickettsia have been shown to be correlated with the insecticide resistance of mosquito and whitefly. The small brown planthopper (SBPH), Laodelphax striatellus, harbours many species of endosymbionts, and has developed a high resistance to buprofezin in China. In this study, we examined the species and the infection incidences of endosymbionts in a buprofezin resistant (BR) strain, a buprofezin-susceptible (BS) strain, and the BR strain after exposure to buprofezin, and we also investigated the change in buprofezin susceptibility after removal of Wolbachia from the BR strain. The results showed that Wolbachia infection incidences were 100% in both the BR and BS strains, but the Wolbachia density in the BR strain was significantly higher than that in the BS strain. There were no significant differences in Arsenophonus infection incidence between the two strains. However, the infection incidence of Serratia and double infection incidence of Serratia + Wolbachia in the BR strain were significantly higher than that in the BS strain. After the BR strain was exposed to 1200 mg/L buprofezin, the infection incidence of Arsenophonus in the surviving individuals increased, and the infection rate of Serratia did not differ, but the double infection incidence of Serratia + Wolbachia decreased. And when a Wolbachia-infected line originating from the BR strain was cleared of Wolbachia, its susceptibility to buprofezin increased. The results suggest that Serratia and Wolbachia infection might improve the buprofezin resistance of SBPH.

AB - The aim of present study is to formulate diphenhydramine nasal nano-emulgels, having lipophilic nano-sized interior droplets, with better penetration for targeted controlled delivery to mucous membrane. Different diphenhydramine (DPH) nasal nano-emulgels were developed having propylene glycol and olive oil (as permeation enhancers) by using RSM for optimization and then evaluated for physico-chemical characteristics and thermal stability. In-vitro drug release through cellophane membrane was conducted and results were analyzed statistically. Further, gelation, mucoadhesive stress, and ex-vivo and histopathological studies were performed on optimized formulation by using goat nasal membrane. Among all formulations, E2 showed maximum DPH release at higher concentration olive oil (4%) and lower concentration propylene glycol (PG) (25%) within 4 h. All formulations have followed first-order kinetics and drug release mechanism was Fickian diffusion. Analysis of variance (ANOVA) and multiple linear regression analysis (MLRA) were used to compare results among formulations and 3D surface plots were constructed also. Optimized formulation showed immediate prolong gelation in artificial nasal mucosa and excellent mucoadhesive property (72.5 +/- 1.5 dynes/cm2). Approximately 97.1% optimized formulation was permeated through membrane within 4 h, having a high flux rate (33.19 +/- 0.897 MUg/cm2/min) with diffusion coefficient (0.000786 +/- 4.56 * 10-5 cm2/min) while drug contents remained on mucosal membrane for 24 h. Histopathologically, change on intra-mucosal surface of excised membrane was observed due to passage of drug through it. In summary, combination of PG and olive oil in nasal DPH nano-emulgel can be utilized successfully for targeted controlled delivery. The optimized formulation has excellent permeability and prolonged residence time on mucosal surface, which prove its good anti-histaminic activity in case of allergic rhinitis.

AB - Proline (Pro) accumulation protects plant cell under abiotic stress. Hydroxyproline (Hyp) as selection agent is a toxic analog of proline and promotes Pro overaccumulation. In this study, Chardonnay calli were firstly irradiated with different dosages of 60Co and then cultured on a Hyp-added medium. Finally, some stable hydroxyproline-resistant (HR) calli were obtained. When calli were cultured on 4 mM Hyp medium for 7 days, intracellular Pro content of the HR calli was five times higher than that detected in the normal calli. The regeneration of HR calli into plantlets was much slower than that of normal ones. When cultured on woody plant medium (WPM) containing 10 mM NaCl for 14 days, HR plantlets still grew well with lower Pro than withered normal plantlets. qRT-PCR results of Pro biosynthesis-related genes in HR plantlets showed that three genes VvP5CS, VvOAT, and VvP5CDH were conducive for Pro accumulation. These results confirmed that HR plantlets acquired salt tolerance ability. We prospect that this procedure to obtain salt-tolerant plants may be valuable to breed programs and improve grapevine genotypes with increased tolerance to salt and other abiotic stresses. PMID- 29569158 TI - Cut-off values of and factors associated with a negative influence on Neck Disability Index. AB - PURPOSE: The Neck Disability Index (NDI) is used to evaluate patients with cervical spine disease. However, few reports have defined the cut-off values of the NDI. The purpose of this study was to identify the cut-off values of and factors with a negative impact on NDI. METHODS: A total of 487 volunteers were divided into three groups based on disability: none, mild, and disabled. The cut off values of the NDI were determined using receiver-operating characteristic curves. After these groups were divided based on sex and age adjustment was performed, the factors with a negative impact on NDI were investigated using multiple logistic regression analysis. RESULTS: Groups none, mild, and disabled included 207, 186, and 94 volunteers, respectively. The cut-off values of the NDI in each group were 0-5, 6-17, and >= 18%, respectively. After adjusting for age, groups none, mild, and disabled had 65, 56, and 23 males, respectively, and 92, 103, and 56 females, respectively. In multiple logistic regression analysis, the factors with a negative impact on NDI in males were manual work (odds ratio [OR] 1.924), higher T1 slope minus cervical lordosis (OR 1.043), and higher C2-7 sagittal vertical axis (OR 1.029, P < 0.05). Among females, the factors were hand grip strength (OR 0.936), body fat percentage (OR 0.942), and sporting activity (OR 0.456, P < 0.05). CONCLUSION: Deterioration in NDI was associated with cervical spinal malalignment and manual labor in males and lack of physical activity and sarcopenia in females.

AB - In the present study, the genetic variations of 17 X-STR markers (DXS8378, DXS9898, DXS7133, GATA31E08, GATA172D05, DXS6801, DXS7423, DXS6809, DXS6799, DXS7132, DXS9902, DXS6800, DXS6789, DXS10075, DXS10079, DXS6807, and DXS6803) were analyzed in 139 unrelated individuals in Nabeul, aiming to perform an X-STR database for anthropological and forensic purposes. Our results indicate that DXS6809 was the most polymorphic locus, whereas DXS6807 was the least informative marker. In addition, the obtained values for the statistical parameters of forensic interest, i.e., the power of discrimination in males (PDM) and females (PDF), as well as the mean exclusion chance in duos (MECD) and trios (MECT) have demonstrated that this panel of 17 X-STRs is highly informative and useful for forensic application and anthropological research. Additionally, pairwise genetic distances based on FST were calculated between Nabeul population and other populations extracted from the literature. Genetic distances were represented in a non-metric MDS plot and clustering of populations according to their geographic locations and their historical relationship was detected. PMID- 29569162 TI - Cranial secular change from the nineteenth to the twentieth century in modern German individuals compared to modern Euro-American individuals. AB - Studying secular changes on human skulls is a central issue in anthropological research, which is however insufficiently investigated for modern German populations. With our study, we focus on morphological cranial variations within Germans during the nineteenth and twentieth centuries. To study this, we recorded different facial landmarks from a cohort study of about 540 German individuals of different age and sex by calculating their cranial size, shape dimensions, and cranial module and cranial capacity to get information about variations occurring during the decades. According to this, measured variables for Germans and Americans, to which we compared our results, were maximum cranial length (glabello-occipital length), basion-bregma height (BBH), basion-nasion length (BNL), maximum cranial breadth (XCB), and cranial base breadth (AUB). Cranial size was calculated as the geometric mean of GOL, BBH, and XCB. Samples were organized into quarter century birth cohorts, with birth years ranging from 1800 to 1950. One-way ANOVA was used to test for variation among cohorts. Over the past 150 years, Americans and Germans showed significant parallel changes, but the American cranium remained relatively higher, with a longer cranial base, as well as narrower than the German cranium. Our results should also lead to the extension of the range of populations listed and investigated for Fordisc(r), a forensic software to identify unknown individuals as from their skeletal remains or just parts of them. Fordisc cannot provide a satisfying identification of European individuals yet because the database is missing enough European reference samples. PMID- 29569163 TI - Reclassification of 400 consecutive glioma cases based on the revised 2016WHO classification. AB - In this study, we reclassified 400 consecutive glioma cases including pediatric cases, using the revised 2016 WHO classification with samples collected from the Kyushu University Brain Tumor Bank. The IDH1/2, H3F3A, key genetic markers in the 2016 classification, were analyzed using high-resolution melting, with DNA extracted from frozen tissues. The 1p/19q codeletions were evaluated using a microsatellite-based loss of heterozygosity analysis, with 18 markers, to detect loss of the entire chromosome arm. In the integrated diagnosis, 29 oligodendroglioma cases and 28 anaplastic oligodendroglioma cases were diagnosed as "IDH-mutant and 1p/19q-codeleted," while 2 oligodendroglioma cases and 5 anaplastic oligodendroglioma cases were diagnosed as not otherwise specified (NOS). These "NOS" cases were either IDH-mutants or 1p/19q-codeleted, although characteristic oligodendroglial features were evident histologically. Better overall survival of patients with oligodendroglioma correlated with the molecular characteristic of "IDH-mutant and 1p/19q-codeleted," rather than the WHO grade. Eleven "glioblastoma, IDH-wild-type" cases were classified as "1p/19q-codeleted", however, chromosome 10 loss was also detected in 10 out of 11 cases. The 2016 WHO criteria for glioma classification leads to better diagnosis of patients. However, there are technical pitfalls and problems to be solved in the molecular analysis of routine diagnostics.

AB - Our investigation is devoted to the theoretical study of the low-lying electronic structure of the LaCl molecule by using ab initio quantum methods. We are concerned with several methods such as the complete active space-self consistent field (CAS-SCF) and the multi reference of configuration interaction (MRCI + Q) methods. These methods are applied for the purpose of drawing the potential energy curves (PECs) and calculating the molecular spectroscopic constants for a given number of electronic states of singlet and triplet multiplicity. We count 26 2S+ 1 Lambda(+/-) electronic states located below 24,000 cm- 1 neglecting the spin-orbit effects and 47 Omega(+/-) components taken into consideration these effects. Our calculations are performed via the quantum ab initio package MOLPRO (Werner and Knowles 2000).

PMID- 29569164 TI - Prognostic and Predictive Factors for Renal Cell Carcinoma. AB - Metastatic renal cell carcinoma (mRCC) is an incurable malignancy, characterized by its resistance to traditional chemotherapy, radiation, and hormonal therapy. Treatment perspectives and prognosis of patients with mRCC have been significantly improved by advances in the understanding of its molecular pathogenesis, which have led to the development of targeted therapeutics. Different molecular factors derived from the tumor or the host detected in both tissue or serum could be predictive of therapeutic benefit. Some of them suggest a rational selection of patients to be treated with certain therapies, though none have been validated for routine use. This article provides an overview of both clinical and molecular factors associated with predictive or prognostic value in mRCC and emphasizes that both should be considered in parallel to provide the most appropriate, individualized treatment and achieve the best outcomes in clinical practice. PMID- 29569167 TI - Microdroplets Accelerate Ring Opening of Epoxides. AB - The nucleophilic opening of an epoxide is a classic organic reaction that has widespread utility in both academic and industrial applications. We have studied the reaction of limonene oxide with morpholine to form 1-methyl-2-morpholino-4 (prop-1-en-2-yl) cyclohexan-1-ol in bulk solution and in electrosprayed microdroplets with a 1:1 v/v water/methanol solvent system. We find that even after 90 min at room temperature, there is no product detected by nuclear magnetic resonance spectroscopy in bulk solution whereas in room-temperature microdroplets (2-3 MUm in diameter), the yield is already 0.5% in a flight time of 1 ms as observed by mass spectrometry. This constitutes a rate acceleration of ~ 105 in the microdroplet environment, if we assume that as much as 5% of product is formed in bulk after 90 min of reaction time. We examine how the reaction rate depends on droplet size, solvent composition, sheath gas pressure, and applied voltage. These factors profoundly influence the extent of reaction. This dramatic acceleration is not limited to just one system. We have also found that the nucleophilic opening of cis-stilbene oxide by morpholine is similarly accelerated. Such large acceleration factors in reaction rates suggest the use of microdroplets for ring opening of epoxides in other systems, which may have practical significance if such a procedure could be scaled.

PMID- 29569168 TI - Development of decellularized amniotic membrane as a bioscaffold for bone marrow derived mesenchymal stem cells: ultrastructural study. AB - Developing effective stem cell-based therapies requires the design of complex in vitro culture systems for accurate representation of the physiological stem cell niche. Human amniotic membrane (hAM) has been successfully used in clinical grafting applications due to its unique biological and regenerative properties. Decellularized hAM (d-hAM) has been previously applied to the culture of human bone marrow mesenchymal stem cells (hMSCs), promoting their expansion and differentiation into adipogenic and osteogenic lineages. In the present study, hAM was decellularized by NaOH-treatment, to provide the three-dimensional (3D) bioscaffold for culturing hMSCs. The ultrastructural differences between intact hAM and decellularized hAM were characterized using the transmission electron microscope (TEM), as well as the 3D interaction between d-hAM and hMSCs cultured on the membrane. TEM examination of the intact hAM showed many microvilli on the epithelial layer cells, active Golgi apparatus, smooth endolplasmic reticulum and the characteristic pinocytic vesicles. The epithelial layer with its structures was absent in the d-hAM. However, no observable difference was detected in the ultrastructural characteristics of the compact stromal layer of d-hAM compared to intact hAM. Both contained bundles of extra cellular matrix (ECM) proteins, and scattered elastic fibres. Cultured human mesenchymal stem cells (hMSCs) examined by TEM appeared oval to spherical in shape and had a rough and non-uniform surface with distinct protrusions or irregular fillopodia. Their diameter ranged from 20.49 to 21.6 um. Most of the cellular organelles were also noticed. SEM examination of the prepared samples revealed unique 3D interaction between the hMSC and d-hAM, where the latter seems to envelop the segments of the hMSCs lying on the surrounding membrane. This study shows that the decellularization process affected the epithelial layer only of hAM and had no effect on altering the presence of ECM components present in the stromal layer of the d-hAM. The interaction between hMSCs and d-hAM maybe mediated by hAM components other than human amniotic epithelial cells, such as ECM components or MSCs present in the deeper spongy layer of the membrane or/and the adhesive components of the basement membrane of the removed epithelial layer. PMID- 29569170 TI - Floral structure and development in Nartheciaceae (Dioscoreales), with special reference to ovary position and septal nectaries. AB - We present a comparative study of the floral structure and development of Nartheciaceae, a small dioscorealean family consisting of five genera (Aletris, Lophiola, Metanarthecium, Narthecium, and Nietneria). A noticeable diversity existed in nine floral characters. Analyses of their respective character states in the light of a phylogenetic context revealed that the flowers of Nartheciaceae, whose plesiomorphies occur in Aletris and Metanarthecium, have evolved toward in all or part of Lophiola, Narthecium, and Nietneria: (1) loss of a perianth tube; (2) stamen insertion at the perianth base; (3) congenital carpel fusion; (4) loss of the septal nectaries; (5) unilocular style; (6) unfused lateral carpellary margins in the style; (7) flower with the median outer tepal on the abaxial side; (8) flower with moniliform hairs; and (9) flower with weak monosymmetry. We further found that, as the flowers developed, the ovary shifted its position from inferior to superior. As a whole, their structure changes suggest that the Nartheciaceae flowers have evolved in close association with pollination and seed dispersal. By considering inferior ovaries and the presence of septal nectaries as plesiomorphies of Nartheciaceae, we discussed evolution of the ovary position and septal nectaries in all the monocots. PMID- 29569169 TI - Flower-like heads from flower-like meristems: pseudanthium development in Davidia involucrata (Nyssaceae). AB - Flower-like inflorescences (pseudanthia) have fascinated botanists for a long time. They are explained as condensed inflorescences implying that the pseudanthium develops from an inflorescence meristem (IM). However, recent developmental studies identified a new form of reproductive meristem, the floral unit meristem (FUM). It differs from IMs by lacking acropetal growth and shares fractionation, expansion and autonomous space filling with flower meristems (FM). The similarity among FUMs and FMs raises the question how far flower-like heads originate from flower-like meristems. In the present paper, pseudanthium development in Davidia involucrata is investigated using scanning electron microscopy. D. involucrata has pincushion-shaped heads composed of densely aggregated, perianthless flowers and associated with two large showy bracts. Early developmental stages show a huge naked FUM. The FMs appear almost simultaneously and lack subtending bracts. With ongoing FUM expansion new space is generated which is immediately used by further FM fractionation. The heads have only staminate flowers or are andromonoecious with staminate and a single perfect flower in oblique position. All FMs lack perianth structures and fractionate a variable number of stamen primordia. The perfect FM is much larger than the staminate FMs and forms a syncarpous gynoecium with inferior ovary. Pseudanthium development in D. involucrata confirms the morphogenetic similarity to FMs as to acropetal growth limitation, meristem expansion and fractionation. It thus should not be interpreted as a condensed inflorescence, but as a flower equivalent. Furthermore as the FUM develops inside a bud, its development is considered to be influenced by mechanical pressure. The oblique position of the perfect flower, the developmental delay of the proximal flowers, and the variable number of stamens which were observed in the pseudanthium development, can be caused by mechanical pressure. Next to the Asteraceae, D. involucrata offers a further example of a pseudanthium originating from a FUM. More knowledge on FUMs is still needed to understand diversification and evolution of flower-like inflorescences. PMID- 29569171 TI - Engineering Ethics Education: A Comparative Study of Japan and Malaysia. AB - This paper reports the findings of a comparative study in which students' perceived attainment of the objectives of an engineering ethics education and their attitude towards engineering ethics were investigated and compared. The investigation was carried out in Japan and Malaysia, involving 163 and 108 engineering undergraduates respectively. The research method used was based on a survey in which respondents were sent a questionnaire to elicit relevant data. Both descriptive and inferential statistical analyses were performed on the data. The results of the analyses showed that the attainment of the objectives of engineering ethics education and students' attitude towards socio-ethical issues in engineering were significantly higher and positive among Japanese engineering students compared to Malaysian engineering students. Such findings suggest that a well-structured, integrated, and innovative pedagogy for teaching ethics will have an impact on the students' attainment of ethics education objectives and their attitude towards engineering ethics. As such, the research findings serve as a cornerstone to which the current practice of teaching and learning of engineering ethics education can be examined more critically, such that further improvements can be made to the existing curriculum that can help produce engineers that have strong moral and ethical characters. PMID- 29569172 TI - A retrospective evaluation of the perioperative drug use and comparison of its cost in robotic vs open surgery for endometrial cancer. AB - To compare the usage and cost of analgesics (opioid and non-opioids), antiemetics, and IV fluids and its associated costs in robotic vs open staging surgery for endometrial cancer (EC). This retrospective study was performed at a single academic institution from January 2014 to June 2017 in the department of Gynecology Oncology at Amrita Institute of Medical Science, Kerala, India. The study included women with biopsy confirmed clinically early stage endometrial cancer or atypical hyperplasia, who underwent robotic-assisted or open staging surgery. Data on surgical time, blood loss, post-anaesthesia care unit (PACU) stay, and length of hospital (LOH) stay; analgesic, antiemetic, and IV fluid use were collected for three distinct periods: intra-operative, PACU, and ward. Direct medicine and material costs associated with the administration of intravenous (IV) fluids, analgesics, and antiemetics were collected. All parameters were compared between two surgical groups. The study included 133 (54 open and 79 robotic-assisted) patients. As compared to open surgery, robotic assisted surgery was associated with significantly reduced: surgical time (p = 0.007), estimated blood loss (p < 0.001), PACU stay (p < 0.001), LOH stay (p < 0.001); IV fluids (crystalloid and colloid; p < 0.001); opioids (p < 0.001), non opioids (intravenous acetaminophen, oral acetaminophen, diclofenac; all p < 0.001); incidence of post-operative nausea and vomiting and the requirement of rescue antiemetics (p < 0.001). EC staging using robotic-assisted surgery was associated with significantly lower medicine and material costs attributed to IV fluids, analgesia, and antiemetics (p < 0.001). As compared to open surgery, robotic surgery was associated with the total saving of $107.7 ($19.5 in IV fluids, $49.2 in analgesics, $1.33 in antiemetics, and $37.8 in material). Robotic-assisted surgical staging for endometrial cancer is associated with decreased requirement and expenditure attributable to post-operative pain, post operative nausea and vomiting, and maintenance and replacement fluid therapy. PMID- 29569173 TI - Ultrastructural Changes and Expression of PCNA and RPE65 in Sodium Iodate-Induced Acute Retinal Pigment Epithelium Degeneration Model. AB - Alteration in retinal pigment epithelium (RPE) results in the visual dysfunction and blindness of retinal degenerative diseases. Injection of sodium iodate (NaIO3) generates degeneration of RPE. We analyzed the sequential ultrastructure and expression of proliferating cell nuclear antigen (PCNA) and retina-specific RPE65 in NaIO3-induced retinal degeneration model. Adult male rats were injected 1% NaIO3 (50 mg/kg) and eyes were enucleated at 1, 3, 5, 7 and 14 days post injection (DPI), fixed, and processed for histological analysis. NaIO3-induced retinal degeneration was successfully established. At 1 DPI, most RPE cells were degenerated and replaced by a few proliferating RPE cells in the peripheral area. At 3 DPI, the RPE and photoreceptor out segments (POS) underwent a marked morphological change, including POS disruption, accumulation of residual bodies in RPE and POS, and hyperplasia of the RPE cell. At 5 DPI, POS showed a maximum increase in the outer segment debris and the retina showed partial detachment. These abnormal morphological changes gradually decreased by day 7. At 14 DPI, the damaged RPE and POS were partially regenerated from the peripheral to the central region. Expression of PCNA and RPE65 increased from day 3 onward. The damaged RPE showed earlier expression of PCNA and RPE65 than POS. The RPE damaged by NaIO3 rapidly proliferated to put down roots on Bruch's membrane from the peripheral retina and proliferation and hyperplasia of the RPE had a regular direction of progress. Therefore, NaIO3-induced acute changes in retina mimic the patho morphologic features of RPE-related diseases. PMID- 29569174 TI - Relationship between Organizational Culture and the Use of Psychotropic Medicines in Nursing Homes: A Systematic Integrative Review. AB - BACKGROUND: Psychotropic medicines are commonly used in nursing homes, despite marginal clinical benefits and association with harm in the elderly. Organizational culture is proposed as a factor explaining the high-level use of psychotropic medicines. Schein describes three levels of culture: artifacts, espoused values, and basic assumptions. OBJECTIVE: This integrative review aimed to investigate the facets and role of organizational culture in the use of psychotropic medicines in nursing homes. METHOD: Five databases were searched for qualitative, quantitative, and mixed method empirical studies up to 13 February 2017. Articles were included if they examined an aspect of organizational culture according to Schein's theory and the use of psychotropic medicines in nursing homes for the management of behavioral and sleep disturbances in residents. Article screening and data extraction were performed independently by one reviewer and checked by the research team. The integrative review method, an approach similar to the method of constant comparison analysis was utilized for data analysis. RESULTS: Twenty-four studies met the inclusion criteria: 13 used quantitative methods, 9 used qualitative methods, 1 was quasi-qualitative, and 1 used mixed methods. Included studies were found to only address two aspects of organizational culture in relation to the use of psychotropic medicines: artifacts and espoused values. No studies addressed the basic assumptions, the unsaid taken-for-granted beliefs, which provide explanations for in/consistencies between the ideal use of psychotropic medicines and the actual use of psychotropic medicines. CONCLUSIONS: Previous studies suggest that organizational culture influences the use of psychotropic medicines in nursing homes; however, what is known is descriptive of culture only at the surface level, that is the artifacts and espoused values. Hence, future research that explains the impact of the basic assumptions of culture on the use of psychotropic medicines is important. PMID- 29569175 TI - Cervical dystonia and substance abuse. AB - OBJECTIVE: To investigate the prevalence of substance abuse (SA) in patients with cervical dystonia (CD) and to correlate it with prevalence of psychiatric disorders. METHODS: Data on anxiety, depression, dystonia severity, and substance abuse were collected from ten sites participating in the Dystonia Coalition. Patients were divided into two groups according to the presence of SA, utilizing Structured Clinical Interview for DSM-4 criteria. Wilcoxon Rank-Sum test was used to analyze the difference in median scores on the questionnaires between the groups. Chi-square test was used to analyze association between opiate and benzodiazepine use and SA. Association between TWSTRS severity and SA and medication use was assessed. A two-tailed p value of < 0.05 was considered significant. SAS 9.3 (SAS Institute Inc., Cary, NC, USA) was used for all analyses. RESULTS: Of 208 CD patients, 23 (11%) were identified with SA; 26.3% of patients with SA were on opiates compared to 7.2% of CD patients without SA (p = 0.006). Compared to non-SA patients, those experiencing SA were more likely male (88.9%; p = 0.0007), younger (median age 55; p = 0.031), and scored worse on questionnaires assessing depression (p = 0.044, p = 0.005), anxiety (p = 0.003), and dystonia psychiatric severity (p = 0.033). The median TWSTRS motor severity scores were higher in SA patients compared to non-SA patients (20 versus 16, p = 0.0339). The median TWSTRS total disability, motor, and pain scores were higher in patients on opiates than patients who were not (12 versus 8, p = 0.0071; 18.5 versus 16, p = 0.0243; 12.4 versus 6.7, p = 0.0052, respectively). CONCLUSIONS: Potential risk factors for SA in CD patients include younger age and male gender with comorbid anxiety, depression and other psychiatric problems. Caution should be exercised when prescribing drugs with potential for abuse in these patients. PMID- 29569177 TI - Uncommon and/or bizarre features of dementia. Part II. AB - In the past decades, clinicians have recognized that dementia may appear as atypical or variant syndromes, as well as the typical form. This study aimed at describing uncommon or bizarre symptoms/syndromes observed in patients suffering from dementia. Medline and Google scholar searches were conducted for relevant articles, chapters, and books published before 2017. Search terms used included delusional jealousy, delusion of pregnancy, dementia, erotomania, folie a deux, and lycanthropy. Publications found through this indexed search were reviewed for further relevant references. The uncommon symptoms/syndromes were described as case reports and there were no systematic investigations. PMID- 29569176 TI - Incidence and outcome of acquired demyelinating syndromes in Dutch children: update of a nationwide and prospective study. AB - INTRODUCTION: Acquired demyelinating syndromes (ADS) are immune-mediated demyelinating disorders of the central nervous system in children. A nationwide, multicentre and prospective cohort study was initiated in the Netherlands in 2006, with a reported ADS incidence of 0.66/100,000 per year and MS incidence of 0.15/100,000 per year in the period between 2007 and 2010. In this study, we provide an update on the incidence and the long-term follow-up of ADS in the Netherlands. METHODS: Children < 18 years with a first attack of demyelination were included consecutively from January 2006 to December 2016. Diagnoses were based on the International Paediatric MS study group consensus criteria. Outcome data were collected by neurological and neuropsychological assessments, and telephone call assessments. RESULTS: Between 2011 and 2016, 55/165 of the ADS patients were diagnosed with MS (33%). This resulted in an increased ADS and MS incidence of 0.80/100,000 per year and 0.26/100,000 per year, respectively. Since 2006 a total of 243 ADS patients have been included. During follow-up (median 55 months, IQR 28-84), 137 patients were diagnosed with monophasic disease (56%), 89 with MS (37%) and 17 with multiphasic disease other than MS (7%). At least one form of residual deficit including cognitive impairment was observed in 69% of all ADS patients, even in monophasic ADS. An Expanded Disability Status Scale score of >= 5.5 was reached in 3/89 MS patients (3%). CONCLUSION: The reported incidence of ADS in Dutch children has increased since 2010. Residual deficits are common in this group, even in monophasic patients. Therefore, long-term follow-up in ADS patients is warranted. PMID- 29569178 TI - The encapsulation of the gemcitabine anticancer drug into grapheme nest: a theoretical study. AB - The efficient transport of a drug molecule until its target cell constitutes a significant challenge for delivery processes. To achieve such objectives, solid nanocapsules that protect the immune system during the transport should be developed and controlled at the nanoscale level. From this point of view, nanostructures based on graphene sheets could present some promising properties due to their ultimate size and dimension. In this work, we present theoretical results using DFT calculations, dealing with a graphene-based delivery system. Indeed, we demonstrate the stability of the gemcitabine anticancer molecule when it is encapsulated into two concave graphene sheets organized as a nest. Quantum calculations showed that the most stable state is located inside the nest, which is then formed by two layers distanced 6 A from each other. For all the optimized systems, we focused on the dependence of the interaction energy on the molecule displacements during its entrance in the graphene nest and its exit from it. We also analyzed their consequence on the local morphological and electronic charge properties. Graphical Abstract Adsorption energy (in eV) of gemcitabine drug during its encapsulation inside the nest of grapheneand its release from it. PMID- 29569179 TI - Parasite Tolerance and Host Competence in Avian Host Defense to West Nile Virus. AB - Competence, or the propensity of a host to transmit parasites, is partly underlain by host strategies to cope with infection (e.g., resistance and tolerance). Resistance represents the ability of hosts to prevent or clear infections, whereas tolerance captures the ability of individuals to cope with a given parasite burden. Here, we investigated (1) whether one easy-to-measure form of tolerance described well the dynamic relationships between host health and parasite burden, and (2) whether individual resistance and tolerance to West Nile virus (WNV) were predictable from single cytokine measures. We exposed house sparrows (HOSP) to WNV and measured subsequent changes in host performance, viral burden, and cytokine expression. We then used two novel approaches (one complex, one simpler) to estimate tolerance within-individual HOSP using four separate host performance traits. We lastly investigated changes in the expression of pro inflammatory cytokine interferon-gamma (IFN-gamma) and anti-inflammatory cytokine interleukin-10 (IL-10). Both approaches to estimating tolerance were equivalent among WNV-infected HOSP; thus, an easy-to-measure tolerance estimation may be successfully applied in field studies. Constitutive expression of IFN-gamma and IL-10 were predictive of resistance and tolerance to WNV, implicating these cytokines as viable biomarkers of host competence to WNV. PMID- 29569181 TI - There and back again: from the origin of life to single molecules. AB - What is life? There is hardly a more fundamental question raised by aspiring researchers, and one less prone to ever be answered in a scientifically satisfying way. In the long, productive and highly influential period of research following his Nobel-recognised work on relaxation kinetics, Manfred Eigen made seminal contributions towards a quantifiable definition of life, with a strong focus on its evolutionary character. In the last years of his time as an active researcher, however, he devoted himself to another, purely experimental topic: the detection and analysis of single biomolecules in aqueous solution. In this short review, I will give an overview of the groundbreaking contributions to the field of single molecule research made by Eigen and coworkers, and show that both, in its intrinsic motivation, and in its consequences, single molecule research strongly relates to the question of the physical-chemical essence of life. In fact, research on living systems with single molecule sensitivity will always refer the researcher to the question of the simplest possible representation, and thus the origin, of any biological phenomenon. PMID- 29569180 TI - Light-regulated promoters for tunable, temporal, and affordable control of fungal gene expression. AB - Regulatable promoters are important genetic tools, particularly for assigning function to essential and redundant genes. They can also be used to control the expression of enzymes that influence metabolic flux or protein secretion, thereby optimizing product yield in bioindustry. This review will focus on regulatable systems for use in filamentous fungi, an important group of organisms whose members include key research models, devastating pathogens of plants and animals, and exploitable cell factories. Though we will begin by cataloging those promoters that are controlled by nutritional or chemical means, our primary focus will rest on those who can be controlled by a literal flip-of-the-switch: promoters of light-regulated genes. The vvd promoter of Neurospora will first serve as a paradigm for how light-driven systems can provide tight, robust, tunable, and temporal control of either autologous or heterologous fungal proteins. We will then discuss a theoretical approach to, and practical considerations for, the development of such promoters in other species. To this end, we have compiled genes from six previously published light-regulated transcriptomic studies to guide the search for suitable photoregulatable promoters in your fungus of interest. PMID- 29569182 TI - Biochemical characterization of rice xylan O-acetyltransferases. AB - MAIN CONCLUSION: Rice xylan is predominantly monoacetylated at O-2 and O-3, and 14 rice DUF231 proteins were demonstrated to be xylan acetyltransferases. Acetylated xylans are the principal hemicellulose in the cell walls of grass species. Because xylan acetylation impedes the conversion of cellulosic biomass into biofuels, knowledge on acetyltransferases catalyzing xylan acetylation in grass species will be instrumental for a better utilization of grass biomass for biofuel production. Xylan in rice (Oryza sativa) is predominantly monoacetylated at O-2 and O-3 with a total degree of acetylation of 0.19. In this report, we have characterized 14 rice DUF231 proteins (OsXOAT1 to OsXOAT14) that are phylogenetically grouped together with Arabidopsis xylan acetyltransferases ESK1 and its close homologs. Complementation analysis demonstrated that the expression of OsXOAT1 to OsXOAT7 in the Arabidopsis esk1 mutant was able to rescue its defects in 2-O- and 3-O-monoacetylation and 2,3-di-O-acetylation. Activity assay of recombinant proteins revealed that all 14 OsXOATs exhibited acetyltransferase activities capable of transferring acetyl groups from acetyl-CoA to the xylohexaose acceptor with 10 of them having high activities. Structural analysis of the OsXOAT-catalyzed products showed that the acetylated structural units consisted mainly of 2-O- and 3-O-monoacetylated xylosyl residues with a minor amount of 2,3-di-O-acetylated xylosyl units, which is consistent with the acetyl substitution pattern of rice xylan. Further kinetic studies revealed that OsXOAT1, OsXOAT2, OsXOAT5, OsXOAT6 and OsXOAT7 had high affinity toward the xylohexaose acceptor. Our results provide biochemical evidence indicating that OsXOATs are acetyltransferases involved in xylan acetylation in rice. PMID- 29569183 TI - TRPV4 is functionally expressed in oligodendrocyte precursor cells and increases their proliferation. AB - Oligodendrocytes, which differentiate from oligodendrocyte precursor cells (OPCs), ensheath axons with myelin, play an essential role in rapid conduction of action potentials and metabolically support neurons. Elucidation of the mechanisms underlying the proliferation, migration, differentiation, and survival of OPCs is considered indispensable for determining the causes of central nervous system diseases. However, the relationship between these functions of OPCs and their intracellular Ca2+ signaling has not been fully elucidated. Here, we investigated the function of transient receptor potential vanilloid 4 (TRPV4), a Ca2+-permeable channel that responds to hypo-osmolarity, mild temperature, mechanical stimulation, and endogenous arachidonic acid metabolites, in OPCs. Trpv4 mRNA was detected in OPCs in vivo and in primary cultured rat OPCs. In Ca2+ imaging experiments, treatment with the selective TRPV4 agonist GSK1016790A induced sustained elevation of the intracellular Ca2+ concentration in OPCs in a concentration-dependent manner, which was almost completely suppressed by co treatment with the selective TRPV4 antagonist HC067047. Stimulation of TRPV4 by GSK1016790A augmented OPC proliferation, which was abolished by co-treatment with HC067047, the intracellular Ca2+ chelator BAPTA-AM, and the protein kinase C inhibitor bisindolylmaleimide II. By contrast, GSK1016790A did not significantly affect the migration or differentiation of OPCs. Taken together, these results suggest that TRPV4 is functionally expressed in OPCs and increases the proliferation of these cells without affecting their ability to differentiate into oligodendrocytes. PMID- 29569184 TI - Mucosal Melanoma: a Literature Review. AB - PURPOSE OF REVIEW: Mucosal melanoma is of great interest due to its aggressive behavior and less favorable prognosis. The literature is mainly case reports and case series. Here, we will collect the knowledge on mucosal melanoma from the last decade and review the literature. The main focus is being site-specific clinical features, treatment, and prognosis. RECENT FINDINGS: The use of immunotherapy gain ground as for others subsets of melanoma. Anti-CTLA-4 and anti PD-1/ PD-L1 blockade in mucosal melanoma have been evaluated in recent studies. Clinical trials are ongoing. The etiology of mucosal melanomas remains unknown. Head and neck mucosal melanomas are most common. Wide excision surgery is the treatment of choice. The effect of adjuvant therapy on survival remains questionable due to the limited knowledge. Radiotherapy seems to give better local control. The overall five-year survival rate for mucosal melanomas is 0 45%. Recent data indicates that this may be improved by the immunotherapy in the years to come. PMID- 29569185 TI - Indications and results of renal biopsy in children: a 36-year experience. AB - BACKGROUND: This study was conducted to investigate retrospectively the indications for renal biopsy (RB) in native kidneys and to analyze pathological findings in a single tertiary pediatric hospital in Southern Italy for the last 36 years. METHODS: All patients who underwent RB at our hospital from 1979 to 2014 were included. All renal tissue specimens were studied under light and immunofluorescent microscopy, while electron microscopy was performed only for specific clinical indications. RESULTS: The study group included 213 patients (female 43.2%) who underwent 225 percutaneous native kidney biopsies. Median age was 10.4 years (range 0.6-24 years). The most frequent indication for RB was nephrotic syndrome (44.4%), followed by proteinuria (27.6%), asymptomatic hematuria (17.3%) and acute kidney injury (9.8%). Gross hematuria appeared after biopsy in less than 5% of the patients, but none of them needed blood transfusion. Adequate renal tissue sample was obtained in 95.5% of the renal biopsies. Primary glomerulonephritis (GN) was the most common finding (61.4%), followed by secondary GN (21.4%), tubulointerstitial diseases (3.7%) and hereditary nephropathy (2.8%), while in 10.7% of the cases, normal renal tissues were found. According to histopathological diagnosis, the most common causes of primary GN were IgA nephropathy (20.9%), followed by minimal change disease (18.1%) and focal segmental glomerulosclerosis (11.6%). CONCLUSIONS: The epidemiology of glomerular disease in our single-center cohort is similar to that shown in other national and international reports. Moreover, our study shows that percutaneous ultrasound-guided RB is a safe, reliable and effective technique in children. PMID- 29569188 TI - Age of Onset in Pedohebephilic Interests. PMID- 29569186 TI - Takotsubo Syndrome: Clinical Features, Pathogenesis, Treatment, and Relationship with Cerebrovascular Diseases. AB - PURPOSE OF REVIEW: This review paper aims to provide a complete and updated overview on the clinical and pathophysiological aspects of Takotsubo syndrome (TTS), including prognosis, therapy, and the association with cerebrovascular conditions. RECENT FINDINGS: TTS is an increasingly recognized non-ischemic cardiomyopathy characterized by sudden, temporary weakening of the myocardium, of which the pathogenesis is unknown. Although pathogenesis of TTS remains unclear, a complex interaction between catecholamine-mediated stimulation, myocardial stunning, and subsequent stress-related myocardial dysfunction seems to be the main pathophysiological mechanism. Stroke is linked to TTS by a dual relationship since it may induce TTS by catecholamine release even if TTS itself also may be complicated by left ventricular thrombi leading to stroke. Given its possible complications, including the association with neurological diseases, both cardiologist and neurologists should be aware about TTS in order to diagnose it promptly and to initiate appropriate therapeutic measures.

AB - Marriages consist of shared experiences and interactions between husbands and wives that may lead to different impressions of the quality of the relationship. Few studies, unfortunately, have tested gender differences in the structure of marital quality, and even fewer studies have evaluated whether genetic and environmental influences on marital quality differ across gender. In this study, we evaluated gender differences in the structure of marital quality using independent samples of married male (n = 2406) and married female (n = 2215) participants from the National Survey of Midlife Development in the United States who provided ratings on twenty-eight marital quality items encompassing six marital quality constructs. We further explored gender differences in genetic and environmental influences on marital quality constructs in a subsample of 491 pairs of twins. Results suggest partial metric invariance across gender but structural variability in marital quality constructs. Notably, correlations between constructs were stronger in women than men. Results also support gender differences in the genetic and environmental influences on different aspects of marital quality. We discuss that men and women may approach and react to marriage differently as the primary reason why we observed differences in the structure of marital quality.

AB - Anemia is a common complication of chronic kidney disease (CKD) in adult and pediatric patients. It has traditionally been treated with erythropoietin therapy and iron supplementation, with great success. With the discovery of the major transcription factor hypoxia inducible factor (HIF) for the erythropoietin gene in 1992, molecules were created that inhibit the HIF prolyl-hydroxylase enzyme. This new class of drug-called HIF stabilizers, or HIF prolyl-hydroxylase inhibitors-prevents the proteasomal degradation of HIF-alpha, thereby inducing upregulation of the erythropoietin gene. This new strategy for treating CKD anemia is already in phase III clinical trials in adults, and the potential advantages of this therapy are that it is orally active (thereby avoiding injections), and patients are exposed to lower circulating levels of erythropoietin. The long-term safety of this strategy, however, requires elucidation in these trials, particularly since there are many other hypoxia sensitive genes, notably, angiogenic factors such as vascular endothelial growth factors (VEGF), as well as glycolytic enzymes. As with all new therapies, it is only once a positive benefit: risk profile has been ascertained in adults that the treatment will translate across into pediatrics. Specific issues in the pediatric CKD population are discussed in this review.

AB - The number of lesbian, gay, and bisexual (LGB) adults aged 50 and older is projected to reach 5 million in the U.S. by 2030 (Fredriksen-Goldsen, Kim, Shiu, Goldsen, & Emlet, 2015). Older bisexuals experience more negative mental and physical health outcomes when compared to both heterosexuals and other sexual minorities (Fredriksen-Goldsen, Shiu, Bryan, Goldsen, & Kim, 2017). As bisexuals are the numeric majority of sexual minorities in the U.S. (Herbenick et al., 2010), bisexual aging processes are critical to understand if researchers wish to reduce sexual minority health disparities and promote healthy aging. In the current study, we use a national probability sample of adults from the Midlife in the United States (MIDUS) study to assess life satisfaction across an 18-year period. We aimed to identify whether life satisfaction-an indicator of psychological health and well-being-is similar for same-age bisexual, lesbian and gay, and heterosexual midlife individuals, and whether sexual orientation predicts change in life satisfaction across adulthood. Further, we tested whether life satisfaction among bisexuals changes at the same rate and in the same pattern as for lesbian, gay, and heterosexual individuals. Overall, we found a linear pattern of increase in life satisfaction across adulthood. However, when we accounted for sexual orientation, a different pattern emerged for bisexuals. Whereas heterosexuals and lesbian and gay individuals experienced increases in life satisfaction across adulthood, bisexuals' life satisfaction did not increase over this period. Implications for bisexual health and well-being are discussed. PMID- 29569191 TI - Urinary CD80 excretion is a predictor of good outcome in children with primary nephrotic syndrome. AB - BACKGROUND: The level of urinary cluster of differentiation 80 (uCD80) is elevated in most children with minimal change disease (MCD) as opposed to focal segmental glomerulosclerosis (FSGS) during the acute phase. The objective of this follow-up study was to evaluate whether uCD80 elevation is actually associated with MCD and whether it signals better prognosis. METHODS: We evaluated uCD80 levels and a series of putative progression factors in a cohort of 64 patients with nephrotic syndrome (NS) seen between 2011 and 2016. We monitored progression of chronic kidney disease (CKD), assessed as a glomerular filtration rate of < 90 ml/min/1.73 m2 for at least 3 months. Patients were classified according to uCD80 level and to the progression rate as calculated by Kaplan-Meier survival analysis and Cox's regression analysis. RESULTS: During a mean follow-up period of 4.8 +/- 0.6 (range 3.5-6.0) years, 13 children (20%) evolved to at least CKD stage 2. The 64 patients with NS and normal baseline renal function were divided into two groups based on uCD80 excretion, i.e. below or above a defined cutoff (< or > 328.98 ng/g creatinine). The predicted response to immunosuppression therapy was 34.5 and 100% in the low- and high-uCD80 excretion, respectively (p < 0.001). Progression to CKD was 41.4 vs. 2.9% in NS patients (p < 0.001). Using the Cox model, only uCD80 excretion (p = 0.013, relative risk 6.171) predicted progression to CKD. CONCLUSIONS: Urinary CD80 predicts progression and remission in children with NS. The use of uCD80 as a prognostic marker facilitates the identification of high-risk patients at an early stage and may lead to better treatment selection.

AB - This study determined if schizophrenia symptom severity and independent living skills at discharge, or while residing in the community, predicted re hospitalization for discharged patients with schizophrenia. A total of 60 patients were discharged from a state psychiatric hospital and had completed assessments at discharge, 6 months, and 1 year post discharge. There were 12 patients who were re-hospitalized. There were no differences between the re hospitalized and not re-hospitalized groups based on third-party ratings of schizophrenia symptom severity and independent living skills. However, the patients' self-report and third party ratings of deteriorating general mental health symptoms 6 months after discharge predicted re-hospitalization. PMID- 29569193 TI - Detection of 2-aminoethylphosphonic acid in suspended particles in an ultraoligotrophic lake: a two-dimensional nuclear magnetic resonance (2D-NMR) study. AB - Particulate organic phosphorus (P) compounds were examined in ultraoligotrophic Lake Saiko, Japan. A cartridge filter was used to collect sufficient amount of suspended particles for analysis by a two-dimensional NMR (1H-31P heteronuclear multiple bond correlation). 2-Aminoethylphosphonic acid (2-AEP), a phosphonate, was detected in suspended particles in Lake Saiko. The identity of the phosphonate was confirmed by comparison with a commercially available compound. Because 2-AEP is bioavailable, microorganisms can store and use this compound under extremely P-limited conditions. This is the first study to detect 2-AEP in an ultra-oligotrophic environment. PMID- 29569194 TI - Hematological and histopathological effects of silver nanoparticles in rainbow trout (Oncorhynchus mykiss)-how about increase of salinity? AB - Hematological and histopathological toxicities of silver nanoparticles (Ag-NPs) to rainbow trout were assessed in three water salinities: 0.4 ppt (low salinity), 6 +/- 0.3 ppt (moderate salinity), and 12 +/- 0.2 ppt (high salinity). The concentrations of Ag-NPs in the low salinity were 0.032, 0.1, 0.32, and 1 ppm, and in the moderate and high salinities were 3.2, 10, 32, and 100 ppm. The results indicated a concentration-dependently increased (thrombocyte, monocyte, and large lymphocyte) and decreased (neutrophil and small lymphocyte) white blood cell count in the Ag-NP treatments in the low salinity than the other ones in the moderate and high salinities. Red blood cell volume significantly increased in all of the experimental groups exposed to higher Ag-NP concentrations, especially those in the low salinity. In the moderate and high salinities, blood plasma total protein decreased in 10 and 32 ppm Ag-NP treatments, but albumin increased in the groups in the low salinity. Blood plasma ions (Cl-, Na+, K+, Ca2+, and Mg2+) showed high changes in the higher Ag-NP treatments. In all treatments, gill histological analysis demonstrated a time- and Ag-NP concentration-dependent extent of abnormalities, with the highest epithelial lifting in 1 ppm Ag-NPs in the low salinity and also the highest necrosis and aneurism in the 32 ppm treatments in other salinities. Lower Ag-NP concentrations in the low salinity led to fibrosis, villus fusion, inflammation, vacuolization, and microvillus hyperplasia in the gut, yet villi lifting and necrosis in 0.32 and 1 ppm of Ag NPs were the main anomalies. In addition to the mentioned alterations, villi abolitions predominantly occurred in 32 ppm Ag-NP concentrations in the moderate and high salinities. Overall, despite exposing to lower Ag-NP concentrations, the fish kept in the low salinity demonstrated more vulnerability to Ag-NPs than those in the other salinities.

PMID- 29569195 TI - Alterations of antioxidant indexes and inflammatory cytokine expression aggravated hepatocellular apoptosis through mitochondrial and death receptor dependent pathways in Gallus gallus exposed to arsenic and copper. AB - In this study, we sought to investigate the effects of sub-chronic exposure of arsenic (As) and copper (Cu) on oxidative stress, inflammatory response, and mitochondria and death receptor apoptosis pathways in chicken liver. Seventy-two 1-day-old male Hy-line chickens were treated with basal diet, 30 mg/kg arsenic trioxide (As2O3), or/and 300 mg/kg copper sulfate (CuSO4) for 4, 8, and 12 weeks. Study revealed that exposure to As or/and Cu undermined the antioxidant function and increased lipid peroxidation. Worse yet, liver cell swollen, vacuolar degeneration, and inflammatory cell infiltration were accompanied by an increase of the nuclear factor-kappaB (NF-kappaB) and its downstream inflammation-related genes after exposure to As or/and Cu. Furthermore, mitochondria swollen and chromatin condensation were found in As and Cu groups, and hepatocyte nuclear membrane rupture and markedly increased (P < 0.01) apoptosis index were observed in As combined with Cu group. Meanwhile, the transcription and protein expression levels of Bcl-2-associated X protein (Bax), p53, cytochrome c (Cyt c), and caspase-3, 8, 9 were upregulated and B cell lymphoma-2 (Bcl-2) was downregulated in As, Cu, and As + Cu groups in the liver tissues (P < 0.05, P < 0.01). Our results indicated that exposure to As or/and Cu could lead to oxidative stress, inflammatory response, and tissue damage and aggravate hepatocellular apoptosis through mitochondrial and death receptor-dependent pathways in chicken liver. And As and Cu showed a possible synergistic relationship in liver damage. PMID- 29569197 TI - Catalytic decomposition of PCDD/Fs on a V2O5-WO3/nano-TiO2 catalyst: effect of NaCl. AB - The effect of NaCl addition on the properties, activity, and deactivation of a V2O5-WO3/nano-TiO2 catalyst was investigated during catalytic decomposition of gas-phase polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). The extent of deactivation relates directly to the NaCl loading of the catalyst. Poisoning by sodium neutralizes acid sites, interacts strongly with active VOx species, and reduces the redox capacity of catalysts. In addition, NaCl is also a chlorine source and may actually accelerate the synthesis of new PCDD/Fs. Washing a catalyst with dilute sulfuric acid largely restores catalytic activity, breaking the interaction of Na+ ions and dispersed vanadia and removing Na from the catalyst surface. Consequently, catalyst acidity and redox capacity almost recover. Furthermore, sulfate residues react with surface adsorbed water to generate Bronsted acid sites, ensuing a surge of strong acidity of the catalysts. PMID- 29569198 TI - Performance modeling and valuation of snow-covered PV systems: examination of a simplified approach to decrease forecasting error. AB - The advent of modern solar energy technologies can improve the costs of energy consumption on a global, national, and regional level, ultimately spanning stakeholders from governmental entities to utility companies, corporations, and residential homeowners. For those stakeholders experiencing the four seasons, accurately accounting for snow-related energy losses is important for effectively predicting photovoltaic performance energy generation and valuation. This paper provides an examination of a new, simplified approach to decrease snow-related forecasting error, in comparison to current solar energy performance models. A new method is proposed to allow model designers, and ultimately users, the opportunity to better understand the return on investment for solar energy systems located in snowy environments. The new method is validated using two different sets of solar energy systems located near Green Bay, WI, USA: a 3.0-kW micro inverter system and a 13.2-kW central inverter system. Both systems were unobstructed, facing south, and set at a tilt of 26.56 degrees . Data were collected beginning in May 2014 (micro inverter system) and October 2014 (central inverter system), through January 2018. In comparison to reference industry standard solar energy prediction applications (PVWatts and PVsyst), the new method results in lower mean absolute percent errors per kilowatt hour of 0.039 and 0.055%, respectively, for the micro inverter system and central inverter system. The statistical analysis provides support for incorporating this new method into freely available, online, up-to-date prediction applications, such as PVWatts and PVsyst. PMID- 29569199 TI - Effect of Cu(II) on the stability of oxyanion-substituted schwertmannite. AB - Schwertmannite, a Fe(III)-oxyhydroxysulfate mineral formed in acidic (pH 3~4), iron- and sulfate-rich acid mine drainage (AMD) environments, tends to undergo phase transformations with changes in pH and redox condition, which may depend on the presence of various trace anions and cations. In the present study, the effects of Cu(II) on the stability of arsenate-, chromate-, and molybdate substituted schwertmannite were investigated. The release of Fe(III) and sulfate from schwertmannite seems to be accelerated in the presence of Cu(II) at pH ~ 3, while Cu(II) retarded the dissolution of schwertmannite at pH ~ 5. XRD and SEM results showed that pure schwertmannite and chromate-substituted schwertmannite underwent transformation to goethite over a 2-month period, the presence of Cu(II) enhanced the stability of the mineral's structure at both pH 3 and 5. However, the structures of arsenate- and molybdate-substituted schwertmannites showed no significant changes in the presence or absence of Cu(II) at both pH 3 and 5. During the phase transformation process, the amount of released oxyanions followed the sequence of chromate > molybdate > arsenate. Moreover, the release of arsenate and chromate from schwertmannite was retarded in the presence of Cu(II) at pH 5, whereas the release of molybdate was promoted. These results have important environmental implications for the stability of schwertmannite and its potential to immobilize contaminant trace elements under AMD conditions. PMID- 29569200 TI - Adaption and use of a quadcopter for targeted sampling of gaseous mercury in the atmosphere. AB - We modified a popular and inexpensive quadcopter to collect gaseous mercury (Hg) on gold-coated quartz cartridges, and analyzed the traps using cold vapor atomic fluorescence spectrometry. Flight times averaged 16 min, limited by battery life, and yielded > 5 pg of Hg, well above the limit of detection (< 0.2 pg). We measured progressively higher concentrations upon both vertical and lateral approaches to a dish containing elemental Hg, demonstrating that the method can detect Hg emissions from a point source. Using the quadcopter, we measured atmospheric Hg near anthropogenic emission sources in the mid-south USA, including a municipal landfill, coal-fired power plant (CFPP), and a petroleum refinery. Average concentrations (+/- standard deviation) immediately downwind of the landfill were higher at ground level and 30 m compared to 60 and 120 m (5.3 +/- 0.5 ng m-3, 5.4 +/- 0.7 ng m-3, 4.2 +/- 0.7 ng m-3, and 2.5 +/- 0.3 ng m-3, respectively). Concentrations were also higher at an urban/industrial area (Memphis) (3.3 +/- 0.9 ng m-3) compared with a rural/background area (1.5 +/- 0.2 ng m-3). Due to airspace flight restrictions near the CFPP and refinery, we were unable to access near-field (stack) plumes and did not observe differences between upwind and downwind locations. Overall, this study demonstrates that highly maneuverable multicopters can be used to probe Hg concentrations aloft, which may be particularly useful for evaluating Hg emissions from remote landscapes and transient sources that are inadequately characterized and leading to uncertainties in ecosystem budgets. PMID- 29569201 TI - Improved sorption of perfluorooctanoic acid on carbon nanotubes hybridized by metal oxide nanoparticles. AB - Multi-walled carbon nanotubes (MWCNTs) are often used as adsorbent because of their strong adsorption capacity. However, due to the nature of MWCNTs, their ability to adsorb perfluorooctanoic acid (PFOA), a highly hydrophobic pollutant, is low. In this study, MWCNTs were modified by three nano metal oxides (nano iron oxide, copper oxide, and zinc oxide). The pristine (as the control) and modified MWCNTs were characterized by BET-N2, TEM, FTIR, XPS, and XRD, which showed that nano metal oxides were well hybridized on the surface of MWCNTs. Radioactive labeled PFOA (14C-PFOA) was used to quantify it at trace level. Adsorption kinetics showed that intra-particle diffusion was the control step of PFOA adsorbing on metal oxides hybridized MWCNTs (MOHCNTs). Adsorption capacity of PFOA on the MOHCNTs was higher than that on the control due to electrostatic and hydrophobic interactions. In addition, PFOA formed inner-sphere complexes with metal oxide nanoparticles via ligand exchange. The alteration of PFOA adsorption capacity by increasing ionic strength was attributed to the aggregation degree of MWCNTs, electrostatic shielding, and/or salting out effect. The presence of Ca2+ increased the adsorption, owing to not only its higher electrostatic shielding ability than Na+ but also its formation of bridge between PFOA and MOHCNTs. PFOA adsorption on MOHCNTs strongly depended on medium pH value. These results provide an innovative approach for removing trace PFOA from liquid medium. PMID- 29569202 TI - Concurrent removal of elemental mercury and SO2 from flue gas using a thiol impregnated CaCO3-based adsorbent: a full factorial design study. AB - Mercury (Hg) emitted from coal-based thermal power plants (CTPPs) can accumulate and bio-magnify in the food chain, thereby posing a risk to humans and wildlife. The central idea of this study was to develop an adsorbent which can concurrently remove elemental mercury (Hg0) and SO2 emitted from coal-based thermal power plants (CTPPs) in a single unit operation. Specifically, a composite adsorbent of CaCO3 impregnated with 2-mercaptobenimidazole (2-MBI) (referred to as modified calcium carbonate (MCC)) was developed. While 2-MBI having sulfur functional group could selectively adsorb Hg0, CaCO3 could remove SO2. Performance of the adsorbent was evaluated in terms of (i) removal (%) of Hg0 and SO2, (ii) adsorption mechanism, (iii) adsorption kinetics, and (iv) leaching potential of mercury from spent adsorbent. The adsorption studies were performed using a 22 full factorial design of experiments with 15 ppbV of Hg0 and 600 ppmV of SO2. Two factors, (i) reaction temperature (80 and 120 degrees C; temperature range in flue gas) and (ii) mass of 2-MBI (10 and 15 wt%), were investigated for the removal of Hg0 and SO2 (as %). The maximum Hg0 and SO2 removal was 86 and 93%, respectively. The results of XPS characterization showed that chemisorption is the predominant mechanism of Hg0 and SO2 adsorption on MCC. The Hg0 adsorption on MCC followed Elovich kinetic model which is also indicative of chemisorption on heterogeneous surface. The toxicity characteristic leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) leached mercury from the spent adsorbent were within the acceptable levels defined in these tests. The engineering significance of this study is that the 2-MBI-modified CaCO3-based adsorbent has potential for concurrent removal of Hg0 and SO2 in a single unit operation. With only minor process modifications, the newly developed adsorbent can replace CaCO3 in the flue-gas desulfurization (FGD) system. PMID- 29569204 TI - Highly cited articles in wind tunnel-related research: a bibliometric analysis. AB - Wind tunnels have been widely employed in aerodynamic research. To characterize the high impact research, a bibliometric analysis was conducted on highly cited articles related to wind tunnel based on the Science Citation Index Expanded (SCI EXPANDED) database from 1900 to 2014. Articles with at least 100 citations from the Web of Science Core Collection were selected and analyzed in terms of publication years, authors, institutions, countries/territories, journals, Web of Science categories, and citation life cycles. The results show that a total of 77 highly cited articles in 37 journals were published between 1959 and 2008. Journal of Fluid Mechanics published the most of highly cited articles. The USA was the most productive country and most frequent partner of internationally collaboration. The prolific institutions were mainly located in the USA and UK. The authors who were both first author and corresponding author published 88% of the articles. The Y index was also deployed to evaluate the publication characteristics of authors. Moreover, the articles with high citations in both history and the latest year with their citation life cycles were examined to provide insights for high impact research. The highly cited articles were almost earliest wind tunnel experimental data and reports on their own research specialty, and thus attracted high citations. It was revealed that classic works of wind tunnel research was frequently occurred in 1990s but much less in 2000s, probably due to the development of numerical models of computational fluid dynamic (CFD) in recent decades. PMID- 29569203 TI - Mancozeb exposure results in manganese accumulation and Nrf2-related antioxidant responses in the brain of common carp Cyprinus carpio. AB - Manganese (Mn)-containing dithiocarbamates such as Mancozeb (MZ) have been shown to induce oxidative stress-related toxicity in rodents and humans. However, little is known about the neurotoxic effects induced by MZ in fish. In this study, carp (Cyprinus carpio) were exposed to non-lethal waterborne concentrations of MZ, and oxidative stress parameters as well as metal accumulation in fish brains were evaluated. The experimental groups were as follows: control, MZ 5 mg/L, and MZ 10 mg/L. Fish were exposed for 7 days, and then brain was removed and prepared for subsequent analysis of antioxidant enzymes, reactive oxygen species (ROS), and expression of Nrf2 and phosphoNrf2. In parallel, manganese (Mn) levels were evaluated in blood and brain tissues. Mn levels were significantly increased in blood and brain of MZ-exposed carps. In addition, a concentration-dependent increase (p < 0.05) in ROS levels was observed in parallel to increments (p < 0.05) in the activity of major antioxidant enzymes, such as GPx, GR, and GST. On the other hand, significant decreases (p < 0.05) in CAT and SOD activities were observed. The expression of total and phosphorylated forms of Nrf2 was significantly (p < 0.05) upregulated in the brain of carps exposed to Mz when compared to the control, indicating an activation of the Nrf2 antioxidant pathway. Our study showed for the first time the activation of the Nrf2/ARE pathway and bioaccumulation of Mn induced by MZ exposure in fish species, highlighting important mechanisms of action and its toxicological impacts to aquatic organisms. PMID- 29569205 TI - The relationship between urban form and air pollution depends on seasonality and city size. AB - Understanding how urban form is related to air pollution is important to urban planning and sustainability, but the urban form-air pollution relationship is currently muddled by inconsistent findings. In this study, we investigated how the compositional and configurational attributes of urban form were related to different air pollution measures (PM2.5, API, and exceedance) in 83 Chinese cities, with explicit consideration of city size and seasonality. Ten landscape metrics were selected to quantify urban form attributes, and Spearman's correlation was used to quantify the urban form-air pollution relationship. Our results show that the urban form and air pollution relationship was dominated by city size and moderated by seasonality. Specifically, urban air pollution levels increased consistently and substantially from small to medium, large, and megacities. The urban form-air pollution relationship depended greatly on seasonality and monsoons. That is, the relationship was more pronounced in spring and summer than fall and winter, as well as in cities affected by monsoons. Urban air pollution was correlated more strongly with landscape composition metrics than landscape configuration metrics which seemed to affect only PM2.5 concentrations. Our study suggests that, to understand how air pollution levels are related to urban form, city size and seasonality must be explicitly considered (or controlled). Also, in order to mitigate urban air pollution problems, regional urban planning is needed to curb the spatial extent of built up areas, reduce the degree of urban fragmentation, and increase urban compactness and contiguity, especially for large and megacities. PMID- 29569206 TI - Incidences of mortality of Indian peafowl Pavo cristatus due to pesticide poisoning in India and accumulation pattern of chlorinated pesticides in tissues of the same species collected from Ahmedabad and Coimbatore. AB - Incidences of mortality of Indian peafowl Pavo cristatus, the national bird (Schedule I Indian Wild Life Protection Act 1972), are rampant in India. Between January 2011 and March 2017, around 550 peafowl in 35 incidences were reported dead across the country. Due to the non-availability of fresh carcases, poisoning could not be confirmed. Birds which died due to kite string injuries in Ahmedabad (15) and accidents in Coimbatore (5) were tested for residues of chlorinated pesticides, namely hexachlorocyclohexane (HCH), dichloro-diphenyl-trichloroethane (DDT), endosulfan, heptachlor, dicofol, dieldrin and cholipyrifos. The liver, kidney and muscle were the tissues considered to document pesticide load. Total load ranged from BDL to 388.2 ng/g. DDT (95%) and HCH (80%) were detected more frequently. DDT (40%) and endosulfan (26%) contributed maximum to the total pesticide load followed by HCH (21%). Pesticide accumulation pattern among the organs was in the order of liver (123.9 ng/g) > kidney (91.9 ng/g) > muscle (19.5 ng/g) with significant difference (p < 0.05). Peafowl from Ahmedabad had significantly (p < 0.05) higher level of total pesticide (149.0 ng/g) than birds from Coimbatore (47.8 ng/g). Although varying levels of chlorinated pesticide were detected, they were below reported toxic limits. Nevertheless, persistence of chlorinated pesticides and poisoning due to modern pesticides across the entire distribution range of Peafowl in India is a cause for concern.

PMID- 29569208 TI - Melanoma and Immune Checkpoint Inhibitors. AB - PURPOSE OF REVIEW: Prognosis of patients with advanced melanoma is dismal with a median overall survival of about 8 months and 5-year overall survival from a diagnosis of metastatic disease of roughly 10%. However, immune checkpoint inhibitors have brought indispensable benefits to melanoma patients. Here we will review the recent clinical efficacy and adverse events of immune checkpoint inhibitors for melanoma patients. RECENT FINDINGS: The immune checkpoint inhibitors increase confirmed objective response and prolong progression-free and overall survival of the afflicted patients in association with maintaining their quality of life. Although diverse immune-related adverse events occur, most of them are manageable by appropriate immunomodulating agents. Clinical efficacy of immune checkpoint inhibitors continues even after discontinuation of drugs. Compared with conventional therapeutic options, the immune checkpoint inhibitors appear to prolong the survival of patients with advanced melanoma. Further clinical trials are warranted to determine whether their combinatory use with other treatment options may augment benefits or not.

PMID- 29569210 TI - A simulation study comparing nine mathematical models of arterial input function for dynamic contrast enhanced MRI to the Parker model. AB - Due to large inter- and intra-patient variabilities of arterial input functions (AIFs), accurately modeling and using patient-specific AIF are very important for quantitative analysis of dynamic contrast enhanced MRI. Computer simulations were performed to evaluate and compare nine population AIF models with the Parker AIF used as 'gold standard'. The Parker AIF was calculated with a temporal resolution of 1.5 s, and then the other nine AIF models were used to fit the Parker AIF. A total of 100 randomly generated volume transfer constants (Ktrans) and distribution volumes (ve) were used to calculate the contrast agent concentration curves based on the Parker AIF and the extended Tofts model with blood plasma volume (vp) = 0.0, 0.01, 0.05 and 0.10. Subsequently, nine AIF models were used to fit these curves to extract physiological parameters (Ktrans, ve and vp). The agreements between generated and extracted Ktrans and ve values were evaluated using Bland-Altman analysis. The effects of the second pass of the Parker AIF model with and without adding Rician noise on extracted physiological parameters were evaluated by 1000 simulations using one of the nine mathematical AIF models closest to the Parker model with the smallest number of parameters. The results demonstrated that a six-parameter linear function plus bi-exponential function AIF model was almost equivalent to the Parker AIF and that the corresponding generated and extracted Ktrans and ve were in excellent agreements. The effects of the second pass of contrast agent circulation were small on extracted physiological parameters using the extended Tofts model, unless noise was added with signal to noise ratio less than 10 dB.

AB - PURPOSE: To review currently available guidelines and recommendations regarding urological follow-up of patients after spinal cord injury (SCI) and present an evidence-based summary to support clinicians in their clinical practice. METHODS: Maximum data were collected according to different methods, including searches with multiple and specific keywords, reference checks, gray literature searches (congress reports, working papers, statement documents), and browsing-related Web site access. Obtained data were analyzed with the modified version of the Oxford grading system for recommendations using levels of evidence (LE) and grades of recommendation (GR). RESULTS: Different surveillance strategies exist, but there is no consensus among authors and organizations. As a result, practice patterns vary around the world. The present review indicates that proper urological follow up of SCI patients should consist of medical history (LE 1-4, GR B-C), clinical examination (LE 4, GR C), renal laboratory tests (LE 1-3, GR B), imaging surveillance of the upper urinary tract (LE 1-3, GR A-B), urodynamic study (LE 2 4, GR B-C), and cystoscopy/cytology (LE 1-4, GR D). Clinicians agree that SCI patients should be followed up regularly with an individually tailored approach. A 1-year follow-up schedule seems reasonable in SCI patients without additional risk factors of renal deterioration (LE 3-4, GR C). In those who manifest risk factors, report changes in bladder behavior, or present with already developed complications of neurogenic bladder dysfunction, follow-up plans should be modified with more frequent checkups (LE 4, GR C). Urodynamic study should be repeated and considered as a routine monitoring strategy. CONCLUSION: Individuals with neurogenic lower urinary tract dysfunction are at increased risk of multiple complications. Nevertheless, proper follow-up after SCI improves the prognosis for these patients and their quality of life.

Cooling of urinary bladder smooth muscle is known as a potent stimulus to micturition due to an increase in muscle tone. The current study investigates the effects of pregnancy on cooling tone and on the rhythmic contractions of the urinary bladder. METHODS: Twenty-four rats were used in this study as control group (non-pregnant) and pregnant group (18-20-day pregnancy). Isolated rat urinary muscle strips were suspended in organ baths containing Krebs' solution for isometric tension recording. RESULTS: Cooling from 37 to 5 degrees C induced a rapid and reproducible increase in basal tone, proportional to cooling temperature. Cooling also increased the rhythmic activity (amplitude and frequency) at 30 and 25 degrees C, then decreased at 20 degrees C, and abolished at 15-5 degrees C. These responses were more pronounced in pregnant group than in control group. Rhythmic contractions were abolished in calcium free, EGTA (1 mM)-containing Krebs' solution and in the presence of nifedipine, while they were not affected by CPA or TTX in both groups. Our investigation showed that the influx of extracellular calcium is important in inducing the rhythmic contractions. CONCLUSIONS: Pregnancy increases cooling-induced contraction in pregnant rat urinary preparations and its rhythmic contractions including amplitude and frequency than non-pregnant rat. Rhythmic contractions are myogenic in nature and highly extracellular calcium dependent. They may play a crucial role in urinary bladder overactivity and incontinence during pregnancy. PMID- 29569214 TI - ESR paper on the proper use of mobile devices in radiology. AB - : Mobile devices (smartphones, tablets, etc.) have become key methods of communication, data access and data sharing for the population in the past decade. The technological capabilities of these devices have expanded very rapidly; for example, their in-built cameras have largely replaced conventional cameras. Their processing power is often sufficient to handle the large data sets of radiology studies and to manipulate images and studies directly on hand-held devices. Thus, they can be used to transmit and view radiology studies, often in locations remote from the source of the imaging data. They are not recommended for primary interpretation of radiology studies, but they facilitate sharing of studies for second opinions, viewing of studies and reports by clinicians at the bedside, etc. Other potential applications include remote participation in educational activity (e.g. webinars) and consultation of online educational content, e-books, journals and reference sources. Social-networking applications can be used for exchanging professional information and teaching. Users of mobile device must be aware of the vulnerabilities and dangers of their use, in particular regarding the potential for inappropriate sharing of confidential patient information, and must take appropriate steps to protect confidential data. KEY POINTS: * Mobile devices have revolutionized communication in the past decade, and are now ubiquitous. * Mobile devices have sufficient processing power to manipulate and display large data sets of radiological images. * Mobile devices allow transmission & sharing of radiologic studies for purposes of second opinions, bedside review of images, teaching, etc. * Mobile devices are currently not recommended as tools for primary interpretation of radiologic studies. * The use of mobile devices for image and data transmission carries risks, especially regarding confidentiality, which must be considered. PMID- 29569213 TI - Prevalence, pathophysiological mechanisms and factors affecting urolithiasis. AB - The formation of urinary stone, urolithiasis, is one the oldest known disease affecting human throughout different civilizations and times. The exact pathophysiological mechanism of urolithiasis is not yet clear, as these calculi are of various types and too complex for simple understanding. A single theory cannot explain its formation; therefore, different theories are presented in various times for its explanation like free particle, fixed particle, Randall's plaque theory. In addition, various factors and components are identified that play an important role in the formation of these urinary calculi. In this review, composition of kidney stones, its prevalence/incidence, explanation of pathophysiological mechanisms and role of various factors; urinary pH, uric acid, parathyroid hormone, citrate, oxalate, calcium and macromolecules; osteopontin, matrix Gla protein, kidney injury molecules, urinary prothrombin fragment-1, Tamm Horsfall protein, inter-alpha-inhibitors, have been discussed in detail. PMID- 29569215 TI - ABCs of the degenerative spine. AB - : Degenerative changes in the spine have high medical and socioeconomic significance. Imaging of the degenerative spine is a frequent challenge in radiology. The pathogenesis of this degenerative process represents a biomechanically related continuum of alterations, which can be identified with different imaging modalities. The aim of this article is to review radiological findings involving the intervertebral discs, end plates, bone marrow changes, facet joints and the spinal canal in relation to the pathogenesis of degenerative changes in the spine. Findings are described in association with the clinical symptoms they may cause, with a brief review of the possible treatment options. The article provides an illustrated review on the topic for radiology residents. TEACHING POINTS: * The adjacent vertebrae, intervertebral disc, ligaments and facet joints constitute a spinal unit. * Degenerative change is a response to insults, such as mechanical or metabolic injury. * Spine degeneration is a biomechanically related continuum of alterations evolving over time.

PMID- 29569217 TI - MRI evaluation of peripheral vascular anomalies using time-resolved imaging of contrast kinetics (TRICKS) sequence. AB - INTRODUCTION: We describe the use of time-resolved imaging of contrast kinetics (TRICKS) sequence in the diagnosis of Peripheral Vascular Anomalies. In case of suspected vascular malformations time-resolved MR angiography might add important information for therapeutic decisions and follow-up. OBJECTIVE: The objective of our study was to assess the usefulness and diagnostic performance of time resolved imaging of contrast kinetics sequence in the evaluation of peripheral vascular anomalies. SUBJECTS AND METHODS: Sixty-six patients (23 pediatric, 43 adult; mean age 26) affected by upper or lower limb vascular anomalies and studied using time-resolved imaging of contrast kinetics sequence were prospectively evaluated. All studies were performed on a 1.5-T whole-body MR system. Two independent readers tried to categorized the suspected vascular anomalies in pre-contrast and post-contrast MR sequences and assessed the overall TRICKS image quality. In 11 patients, the diagnostic performance comparability between TRICKS sequence and digital subtraction angiography was evaluated. RESULTS: On the basis of time-resolved imaging of contrast kinetics, 31 of the vascular anomalies were classified as high-flow vascular malformations, 29 as low flow vascular lesions and 6 as hemangiomas. There was no significant difference in image quality evaluation and vascular anomaly classification between the two observers. The vascular anomalies characteristics provided by moderate, good or excellent quality TRICKS images were confirmed by digital subtraction angiography. CONCLUSION: Time-resolved imaging of contrast kinetics sequence let the radiologist to acquire useful temporal information to correctly evaluate vascular anomalies components, adding more data to those provided by conventional MR sequences, especially in case of arteriovenous malformation. Therefore, both in pediatric and adult population, TRICKS could be used as an additional initial diagnostic tool to rightly classify these lesions and evaluate if a treatment is needed and which. PMID- 29569218 TI - CT features of diffuse lung disease in infancy. AB - Diffuse lung disease in infancy includes a wide range of very rare and peculiar pulmonary conditions usually not seen in older children, in whom diffuse lung disease has much greater overlap with adult disorders. The acronym chILD (childhood Interstitial Lung Disease) commonly defines these disorders, although air spaces, airways, alveolar epithelium, vasculature, pleura, and pleural spaces can also be involved, besides the pulmonary interstitium. chILD can be caused by diffuse developmental disorders, alveolar growth abnormalities, surfactant dysfunction disorders, and other specific conditions of poorly understood etiology. Chest CT imaging studies play a pivotal role in the evaluation of chILD. In some conditions CT findings can be specific, and thus make it possible avoiding further testing. In other disorders, findings are nonspecific, although they may suggest a diagnostic pattern and guide further testing. Nevertheless, chILD disorders often remain unrecognized on imaging studies, as they are very rare. The aim of this article is to review the CT patterns of lung involvement in a series of infants with chILD. PMID- 29569219 TI - Dopamine D2 agonist affects visuospatial working memory distractor interference depending on individual differences in baseline working memory span. AB - The interplay of dopaminergic striatal D1-D2 circuits is thought to support working memory (WM) by selectively filtering information that is to be remembered versus information to be ignored. To test this theory, we conducted an experiment in which healthy participants performed a visuospatial working memory (VSWM) task after ingesting the D2-receptor agonist cabergoline (or placebo), in a randomized, double-blinded, crossover design. Results showed greater interference from distractors under cabergoline, particularly for individuals with higher baseline dopamine (indicated by WM span). These findings support computational theories of striatal D1-D2 function during WM encoding and distractor-filtering, and provide new evidence for interactive cortico-striatal systems that support VSWM capacity and their dependence on WM span. PMID- 29569220 TI - Quantification of terpene trilactones in Ginkgo biloba with a 1H NMR method. AB - Ginkgo biloba L. has been used as a herbal medicine in the traditional treatment of insufficient blood flow, memory deficits, and cerebral insufficiency. The terpene trilactone components, the bioactive agents of Ginkgo biloba L., have also been reported to exhibit useful functionality such as anti-inflammatory and neuroprotective effects. Therefore, in the present research, we attempted to analyze quantitatively the terpene trilactone components in Ginkgo biloba leaf extract, with quantitative 1H NMR (qNMR) and obtained almost identical results to data reported using HPLC. Application of the qNMR method for the analysis of the terpene trilactone contents in commercial Ginkgo extract products, such as soft gel capsules and tablets, produced the same levels noted in package labels. Thus, qNMR is an alternative method for quantification of the terpene trilactone components in commercial Ginkgo extract products. PMID- 29569221 TI - Cellular mechanism for herbal medicine Junchoto to facilitate intestinal Cl /water secretion that involves cAMP-dependent activation of CFTR. AB - Constipation is a common symptom frequently compromising the quality of daily life. Several mechanistically different drugs have been used to mitigate constipation, including Japanese herbal (Kampo) medicines. However, the mechanisms of their actions are often not well understood. Here we aimed to investigate the molecular mechanisms underlying the effects of Junchoto (JCT), a Kampo medicine empirically prescribed for chronic constipation. Cl- channel activity was measured by the patch-clamp method in human cystic fibrosis transmembrane conductance regulator (CFTR)-expressing HEK293T cells and human intestinal Caco-2 cells. cAMP was measured by a luciferase-based assay. Cell volume change was measured by a particle-sizing and particle-counting analyzer and video-microscopic measurement. In both CFTR-expressing HEK293T and Caco-2 cells, JCT dose-dependently induced whole-cell currents showing typical biophysical and pharmacological features of CFTR. Robust expression of CFTR was confirmed by RT-PCR and Western blotting in Caco-2 cells. Luciferase-based measurement revealed that JCT increases intracellular cAMP levels. Administration of the adenylate cyclase inhibitor SQ22536 or CFTR inhibitor-172, or treatment with small interfering RNAs (siRNA) targeting CFTR, abolished JCT-induced whole cell currents, suggesting that elevated intracellular cAMP by JCT causes activation of CFTR in Caco-2 cells. Finally, blockade of CFTR activity by CFTR inhibitor-172 or siRNA-knockdown of CFTR or application of SQ22536 markedly reduced the degree of cell volume decrease induced by JCT. JCT can induce a Cl- efflux through the CFTR channel to promote water secretion, and this effect is likely mediated by increased cAMP production. PMID- 29569222 TI - Two new pyrrolo-2-aminoimidazoles from a Myanmarese marine sponge, Clathria prolifera. AB - Marine organisms such as marine sponges and soft corals are valuable sources of pharmacologically active secondary metabolites. In our ongoing research on the discovery of new secondary metabolites from marine organisms, two new pyrrolo-2 aminoimidazoles, clathriroles A (1) and B (2), were isolated from the water soluble portion prepared from the methanol and acetone (2:1) extract of the marine sponge, Clathria prolifera, collected in Myanmar. The chemical structures of the isolated compounds were determined using extensive spectroscopic techniques, including NMR, HRESIMS, IR, and optical rotation, and comparisons with the reported literature. The spectroscopic analyses of 1 and 2 suggested that 1 is an enantiomer of antifungal N-methylmanzacidin C isolated from the marine sponge Axinella brevistyla, whereas 2 is a diastereomer of manzacidin D at C-11 isolated from the marine sponge Astrosclera willeyana. To the best of our knowledge, this is the first report of the isolation of the pyrrolo-2 aminoimidazole compounds from C. prolifera. Furthermore, in contrast to the potency of N-methylmanzacidin C against Saccharomyces cerevisiae, the antifungal assay revealed that 1 and 2 lack any activity against this strain. Thus, these observations may suggest that the absolute configurations at both C-9 and C-11 play an important role in controlling the antifungal activity of this type of compound.

PMID- 29569223 TI - Appetite-enhancing effects of vanilla flavours such as vanillin. AB - Vanilla flavour is familiar to consumers through foods, cosmetics, household products and some medicines. Vanilla flavouring agents typically contain vanillin or its analogue ethyl vanillin. Our previous study revealed that the inhalation of eugenol, which contains a vanillyl group, has an appetite-enhancing effect, and the inhalation of aroma compounds containing the vanillyl group or its analogues led to increased food intake in mice. Here, we found that vanillin, ethyl vanillin and eugenol showed appetite-enhancing effects, whereas isoeugenol and safrole did not. These results suggest that the appetite-enhancing effects could be attributable to the vanillyl group and could be affected by the position of the double bond in the aliphatic chain. Furthermore, the results of intraperitoneal administration of eugenol and vanillin suggest that their appetite-enhancing effects could occur via stimulation of olfactory receptors. PMID- 29569225 TI - A statistical model for helices with applications. AB - Motivated by a cutting edge problem related to the shape of alpha helices in proteins, we formulate a parametric statistical model, which incorporates the cylindrical nature of the helix. Our focus is to detect a "kink," which is a drastic change in the axial direction of the helix. We propose a statistical model for the straight alpha helix and derive the maximum likelihood estimation procedure. The cylinder is an accepted geometric model for alpha helices, but our statistical formulation, for the first time, quantifies the uncertainty in atom positions around the cylinder. We propose a change point technique "Kink-Detector" to detect a kink location along the helix. Unlike classical change point problems, the change in direction of a helix depends on a simultaneous shift of multiple data points rather than a single data point, and is less straightforward. Our biological building block is crowdsourced data on straight and kinked helices; which has set a gold standard. We use this data to identify salient features to construct Kink-detector, test its performance and gain some insights. We find the performance of Kink-detector comparable to its computational competitor called "Kink-Finder." We highlight that identification of kinks by visual assessment can have limitations and Kink-detector may help in such cases. Further, an analysis of crowdsourced curved alpha helices finds that Kink-detector is also effective in detecting moderate changes in axial directions.

PMID- 29569226 TI - Inherited pulmonary cylindromas: extending the phenotype of CYLD mutation carriers. AB - BACKGROUND: Germline mutations in the tumour suppressor gene CYLD are recognized to be associated with the development of multiple cutaneous cylindromas. We encountered such a patient who presented with breathlessness because of multiple pulmonary cylindromas. OBJECTIVES: To search for clinical and radiological features of multiple pulmonary cylindromas in a cohort of 16 patients with CYLD mutations. METHODS: A retrospective case-note review was carried out in a tertiary dermatogenetics clinic where CYLD mutation carriers are reviewed on an annual basis. In-depth investigation was carried out for patients with pulmonary tumours. RESULTS: Four patients had radiological imaging of their lungs, of which two had multiple pulmonary cylindromas that were confirmed histologically. Serial computed tomography monitoring allowed for pre-emptive endobronchial laser ablation, preventing major airway obstruction and pulmonary collapse. CONCLUSIONS: Pulmonary cylindromas are an unrecognized, but infrequently symptomatic, aspect of the phenotype in these patients that can have implications for patient care. They should be considered in patients with a high tumour burden that present with respiratory symptoms, and where appropriate, monitored with serial imaging. PMID- 29569228 TI - Model-averaged confounder adjustment for estimating multivariate exposure effects with linear regression. AB - In environmental and nutritional epidemiology and in many other fields, there is increasing interest in estimating the effect of simultaneous exposure to several agents (e.g., multiple nutrients, pesticides, or air pollutants) on a health outcome. We consider estimating the effect of a multivariate exposure that includes several continuous agents and their interactions-on an outcome, when the true confounding variables are an unknown subset of a potentially large (relative to sample size) set of measured covariates. Our approach is rooted in the ideas of Bayesian model averaging: the exposure effect is estimated as a weighted average of the estimated exposure effects obtained under several linear regression models that include different sets of the potential confounders. We introduce a data-driven prior that assigns to the likely confounders a higher probability of being included into the regression model. We show that our approach can also be formulated as a penalized likelihood formulation with an interpretable tuning parameter. Through a simulation study, we demonstrate that the proposed approach identifies parsimonious models that are fully adjusted for observed confounding and estimates the multivariate exposure effect with smaller mean squared error compared to several alternatives. We apply the method to an Environmental Wide Association Study using National Heath and Nutrition Examination Survey to estimate the effect of mixtures of nutrients and pesticides on lipid levels. PMID- 29569229 TI - Diagnostic accuracy of dermatofluoroscopy in cutaneous melanoma detection: results of a prospective multicentre clinical study in 476 pigmented lesions. AB - BACKGROUND: Early detection is a key factor in improving survival from melanoma. Today, the clinical diagnosis of cutaneous melanoma is based mostly on visual inspection and dermoscopy. Preclinical studies in freshly excised or paraffin embedded tissue have shown that the melanin fluorescence spectra after stepwise two-photon excitation, a process termed dermatofluoroscopy, differ between cutaneous melanoma and melanocytic naevi. However, confirmation from a larger prospective clinical study is lacking. OBJECTIVES: The primary end point of this study was to determine the diagnostic accuracy of dermatofluoroscopy in melanoma detection. Secondary end points included the collection of data for improving the computer algorithm that classifies skin lesions based on melanin fluorescence and the assessment of safety aspects. METHODS: This was a prospective, blinded, multicentre clinical study in patients with pigmented skin lesions (PSLs) indicated for excision either to rule out or to confirm cutaneous melanoma. All included lesions underwent dermoscopy and dermatofluoroscopy in vivo before lesions were excised and subjected to histopathological examination. RESULTS: In total, 369 patients and 476 PSLs were included in the final analysis. In 101 of 476 lesions (21.2%) histopathology revealed melanoma. The observed sensitivity of dermatofluoroscopy was 89.1% (90 of 101 melanomas identified), with an observed specificity of 44.8%. The positive and negative predictive values were 30.3% and 93.9%, respectively. No adverse events occurred. CONCLUSIONS: Dermatofluoroscopy is a safe and accurate diagnostic method to aid physicians in diagnosing cutaneous melanoma. Limitations arise from largely amelanotic or regressing lesions lacking sufficient melanin fluorescence. PMID- 29569230 TI - Socioeconomic status and risk of intensive care unit admission with sepsis. AB - BACKGROUND: A recent study showed higher risk of bacteremia among individuals with low socioeconomic status (SES). We hypothesized that patients with a low SES have a higher risk of intensive care unit (ICU) admission with sepsis compared to patients with higher SES. METHODS: This was a case-control study on patients with sepsis admitted to the ICU at Aarhus University Hospital, Denmark (2008-2010). Three hundred eighty-three sepsis patients were matched on sex, age, and zip code with controls retrieved from the background population. SES was defined as highest accomplished educational level, yearly income, cohabitation status, and occupation. The odds ratio (OR) of being admitted with sepsis to the ICU was calculated using conditional logistic regression, adjusting for the Charlson Comorbidity Index and the remaining socioeconomic variables. RESULTS: The adjusted odds of being admitted to the ICU with sepsis were significantly higher among individuals living alone (OR 1.72, 95% confidence interval (CI) 1.33-2.24, P < 0.001) compared to individuals living with a cohabitant. Individuals outside the labor force had an adjusted OR of 3.50 (CI 2.36-5.18, P < 0.001) compared to individuals in the labor force. Individuals with a medium level of education had an increased risk of admission to the ICU with sepsis compared to a high level of education (adjusted OR 1.43, CI 1.02-2.00, P = 0.04). There was no significant association between income and risk of ICU admission with sepsis after adjustment. CONCLUSION: Individuals living alone, being outside the labor force, or having a medium level of education had significantly higher risk of ICU admission with sepsis.

AB - Competition is an important determinant of assemblage structure and population regulation, often resulting in decreased growth, fecundity or survival. In corals, most studies testing for an effect of competition on demographic traits, such as growth, have been experimental and often impose very high levels of competition upon colonies. To more realistically assess the role of competition on coral traits, multispecies studies in the wild are required. Here, we use 5 yr of data that includes 11 coral species on the reef crest at Lizard Island on the Great Barrier Reef to quantify the effect of competition on growth. Additionally, we test whether species differ in their susceptibility to direct-contact (overgrowth and digestion) and overtopping competition, and whether species from some morphological groups are more likely to compete with one another than with species from other morphological groups. We also investigate the relationships between competitive ability and three key traits: growth rate, mechanical stability and fecundity. In contrast to most previous work using field manipulations of competition, we found a negligible effect of competition on growth. Acropora species consistently won overtopping encounters but lost in direct-contact encounters, and these results were consistent among the four Acropora morphological groups. In contrast, the massive Goniastrea spp. were poor at overtopping but generally won direct-contact encounters. Only tabular colonies were disproportionally more likely to compete against one another than with other morphologies. This propensity increases intraspecific relative to interspecific competition, a phenomenon that can promote coexistence when it is present among dominant competitors. Good competitors grew more quickly and had higher fecundity but were less mechanically stable, implying a tradeoff between performance during disturbance vs. performance in the absence of disturbance. We conclude that competition among adults is less likely to influence community dynamics than previously thought. If competition does have an effect, it is more likely to occur at life-stages other than adults. PMID- 29569235 TI - Application of ERT, Saline Tracer and Numerical Studies to Delineate Preferential Paths in Fractured Granites. AB - Accurate quantification of in situ heterogeneity and flow processes through fractured geologic media remains elusive for hydrogeologists due to the complexity in fracture characterization and its multiscale behavior. In this research, we demonstrated the efficacy of tracer-electrical resistivity tomography (ERT) experiments combined with numerical simulations to characterize heterogeneity and delineate preferential flow paths in a fractured granite aquifer. A series of natural gradient saline tracer experiments were conducted from a depth window of 18 to 22 m in an injection well (IW) located inside the Indian Institute of Technology Hyderabad campus. Tracer migration was monitored in a time-lapse mode using two cross-sectional surface ERT profiles placed in the direction of flow gradient. ERT data quality was improved by considering stacking, reciprocal measurements, resolution indicators, and geophysical logs. Dynamic changes in subsurface electrical properties inferred via resistivity anomalies were used to highlight preferential flow paths of the study area. Temporal changes in electrical resistivity and tracer concentration were monitored along the vertical in an observation well located at 48 m to the east of the IW. ERT-derived tracer breakthrough curves were in agreement with geochemical sample measurements. Fracture geometry and hydraulic properties derived from ERT and pumping tests were further used to evaluate two mathematical conceptualizations that are relevant to fractured aquifers. Results of numerical analysis conclude that dual continuum model that combines matrix and fracture systems through a flow exchange term has outperformed equivalent continuum model in reproducing tracer concentrations at the monitoring wells (evident by a decrease in RMSE from 199 to 65 mg/L). A sensitivity analysis on model simulations conclude that spatial variability in hydraulic conductivity, local scale dispersion, and flow exchange at fracture-matrix interface have a profound effect on model simulations. PMID- 29569236 TI - Predicting ecosystem vulnerability to biodiversity loss from community composition. AB - Ecosystems vary widely in their responses to biodiversity change, with some losing function dramatically while others are highly resilient. However, generalizations about how species- and community-level properties determine these divergent ecosystem responses have been elusive because potential sources of variation (e.g., trophic structure, compensation, functional trait diversity) are rarely evaluated in conjunction. Ecosystem vulnerability, or the likely change in ecosystem function following biodiversity change, is influenced by two types of species traits: response traits that determine species' individual sensitivities to environmental change, and effect traits that determine a species' contribution to ecosystem function. Here we extend the response-effect trait framework to quantify ecosystem vulnerability and show how trophic structure, within-trait variance, and among-trait covariance affect ecosystem vulnerability by linking extinction order and functional compensation. Using in silico trait-based simulations we found that ecosystem vulnerability increased when response and effect traits positively covaried, but this increase was attenuated by decreasing trait variance. Contrary to expectations, in these communities, both functional diversity and trophic structure increased ecosystem vulnerability. In contrast, ecosystem functions were resilient when response and effect traits covaried negatively, and variance had a positive effect on resiliency. Our results suggest that although biodiversity loss is often associated with decreases in ecosystem functions, such effects are conditional on trophic structure, and the variation within and covariation among response and effect traits. Taken together, these three factors can predict when ecosystems are poised to lose or gain function with ongoing biodiversity change. PMID- 29569237 TI - Workforce participation and activities in Parkinson's disease patients receiving device-aided therapy. AB - OBJECTIVES: Many countries have an aging population, and it is thus likely that Parkinson's disease (PD) will become an increasing health problem. It is important to ensure this group can use their resources in the best way possible, including remaining in the work market. This study aimed to investigate workforce participation and daily activities among patients with PD receiving device-aided therapy to provide new knowledge that may be used to inform decisions about these therapy options. MATERIALS AND METHODS: This was a retrospective, descriptive quantitative pilot study, including 67 patients with PD from 3 centers in Sweden and Denmark. Included patients were younger than 67 years at the time of introduction of device-aided therapy. Eligible patients were identified by the Swedish national Parkinson patient registry or by the treating neurologist. Quantitative interviews were made by telephone. RESULTS: A majority of the patients could perform the same, or more, amount of activities approximately 5 years after the introduction of device-aided therapy. A small number of patients receiving deep brain stimulation (DBS) and levodopa-carbidopa intestinal gel (LCIG) were able to increase their work capacity within 1 year of initiating device-aided therapy and a remarkably high share could still work at the end point of this study, approximately 15 years since the diagnosis of PD. CONCLUSIONS: Device-aided therapy may sustain or increase daily activities and workforce participation in patients with PD who have not yet reached retirement age. There is need for prospective studies, both quantitative and qualitative, to confirm these results.

AB - AIMS: To generate an Arabic version of the Organizational Commitment Questionnaire that would be easily understood by Arabic speakers and would be sensitive to Arabic culture. BACKGROUND: The nursing workforce in Saudi Arabia is undergoing a process of Saudization but there is a need to understand the factors that will help to retain this workforce. INTRODUCTION: No organizational commitment tools exist in Arabic that are specifically designed for health organizations. An Arabic version of the organizational commitment tool could aid Arabic speaking employers to understand their employees' perceptions of their organizations. METHODS: Translation and back-translation followed by factor analysis (principal components analysis and confirmatory factor analysis) to test the factorial validity and item response theory (Mokken scaling). RESULTS: A two factor structure was obtained for the Organizational Commitment Questionnaire comprising Factor 1: Value commitment; and Factor 2: Commitment to stay with acceptable reliability measured by internal consistency. A Mokken scale was obtained including items from both factors showing a hierarchy of items running from commitment to the organization and commitment to self. DISCUSSION: This study shows that the Arabic version of the OCQ retained the established two factor structure of the original English-language version. Although the two factors - 'value commitment' and 'commitment to stay' - repudiate the original developers' single factor claim. CONCLUSION: A useful insight into the structure of the Organizational Commitment Questionnaire has been obtained with the novel addition of a hierarchical scale. IMPLICATIONS FOR NURSING POLICY: The Organizational Commitment Questionnaire is now ready to be used with nurses in the Arab speaking world and could be used a tool to measure the contemporary commitment of nursing employees and in future interventions aimed at increasing commitment and retention of valuable nursing staff. PMID- 29569239 TI - Integrating species traits into species pools. AB - Despite decades of research on the species-pool concept and the recent explosion of interest in trait-based frameworks in ecology and biogeography, surprisingly little is known about how spatial and temporal changes in species-pool functional diversity (SPFD) influence biodiversity and the processes underlying community assembly. Current trait-based frameworks focus primarily on community assembly from a static regional species pool, without considering how spatial or temporal variation in SPFD alters the relative importance of deterministic and stochastic assembly processes. Likewise, species-pool concepts primarily focus on how the number of species in the species pool influences local biodiversity. However, species pools with similar richness can vary substantially in functional-trait diversity, which can strongly influence community assembly and biodiversity responses to environmental change. Here, we integrate recent advances in community ecology, trait-based ecology, and biogeography to provide a more comprehensive framework that explicitly considers how variation in SPFD, among regions and within regions through time, influences the relative importance of community assembly processes and patterns of biodiversity. First, we provide a brief overview of the primary ecological and evolutionary processes that create differences in SPFD among regions and within regions through time. We then illustrate how SPFD may influence fundamental processes of local community assembly (dispersal, ecological drift, niche selection). Higher SPFD may increase the relative importance of deterministic community assembly when greater functional diversity in the species pool increases niche selection across environmental gradients. In contrast, lower SPFD may increase the relative importance of stochastic community assembly when high functional redundancy in the species pool increases the influence of dispersal history or ecological drift. Next, we outline experimental and observational approaches for testing the influence of SPFD on assembly processes and biodiversity. Finally, we highlight applications of this framework for restoration and conservation. This species pool functional diversity framework has the potential to advance our understanding of how local- and regional-scale processes jointly influence patterns of biodiversity across biogeographic regions, changes in biodiversity within regions over time, and restoration outcomes and conservation efforts in ecosystems altered by environmental change.

AB - BACKGROUND: A pilot scale process consisting of ultrasound-assisted extraction, ammonium sulfate precipitation, cross-flow ultrafiltration and AB-8 macroporous resins purification aiming to recover anthocyanins and zein from purple corn (PC) was optimized and scaled-up. The effects of five independent variables (ethanol concentration, liquid to solid ratio, ultrasound temperature, time and power) were discussed and the most influential factors were optimized. RESULTS: The highest total anthocyanin (0.45 +/- 0.01 g kg-1 ) and zein (17.14 +/- 1.73 g kg-1 ) contents from purple corn were obtained using an ultrasound power of 105 W, an extraction time of 90 min, an ethanol concentration of 74% and a liquid to solid ratio of 26:1, at 70 degrees C, and this was consistent with the predicted values (0.46 and 17.36 g kg-1 , for anthocyanin and zein, respectively). Subsequently, ammonium sulfate precipitation was used to isolate anthocyanins and zein. After cross-flow ultrafiltration, zein (6.30 g) was obtained with 80% purity. Anthocyanins were purified by AB-8 macroporous resins, resulting in 1.60 g of anthocyanins. High-performance liquid chromatography-electrospray ionization mass spectrometry analysis revealed eight different anthocyanins in purple corn extracts. CONCLUSION: From the results obtained in the present study, it can be concluded that the proposed extraction-separation-filtration-purification method applied under the optimal conditions could be scaled-up to recover anthocyanins and zein simultaneously. Moreover, under the selected conditions, no significant degradation of anthocyanins was observed. (c) 2018 Society of Chemical Industry.

AB - BACKGROUND: Omega-3 and omega-6 fatty acids-rich oils suffer oxidation reactions that alter their chemical and organoleptic quality. Microencapsulation can be a powerful tool for protection against ambient conditions. In the present study, the addition of microencapsulated chia oil as an ingredient in bread preparations and its effect on the technological and chemical quality of breads was investigated. RESULTS: Microencapsulation of chia oil was carried out by freeze drying with soy proteins as wall material and oil release was determined under in vitro gastric and intestinal conditions. Encapsulated oil-containing bread showed no differences in specific volume, average cell area, firmness and chewiness with respect to control bread. Unencapsulated oil-containing bread showed a marked increase in hydroperoxide values respect to control, whereas encapsulated oil containing bread values were not affected by baking and bread storage. The fatty acid profiles showed a decrease of 13% and 16%, respectively, in alpha-linolenic acid in the encapsulated and unencapsulated oils with respect to bulk chia oil. Sensory analysis showed no significant differences between bread samples. CONCLUSION: The addition of encapsulated chia oil did not alter the technological quality of breads and prevented the formation of hydroperoxide radicals. A ration of encapsulated oil-containing bread contributes 60% of the recommended dietary intake of omega-3 fatty acids. (c) 2018 Society of Chemical Industry. PMID- 29569242 TI - Egg-Yolk Sphingomyelin and Phosphatidylcholine Attenuate Cholesterol Absorption in Caco-2 Cells. AB - Phospholipids have been shown to modulate intestinal cholesterol absorption in cells and animals, a process that is regulated by several transporter proteins. Of these proteins, Niemann-Pick C1-Like 1 (NPC1L1) is a major contributor to this process. The mechanism by which phospholipids modulate cholesterol absorption remains unknown. Here, we evaluate the effects of egg-yolk phospholipids on cholesterol absorption and transport in human colon carcinoma cell line (Caco-2 cells) and on the expression of NPC1L1 and others proteins associated with cholesterol absorption (ABCG5, ABCG8, ABCA1, ACAT2, MTP, CAV-1, ANX-2). The roles of SREBP-1 and SREBP-2 in this process were also investigated. The results show that egg-yolk sphingomyelin (CerPCho) and phosphatidylcholine (PtdCho) inhibit cholesterol transport in the Caco-2 monolayer in a dose-dependent manner. These might be due to the decrease of the cholesterol solubility in micelles as well as to the increases in the micellar sizes and the bile acid-binding capacity. Furthermore, the treatments with egg-yolk CerPCho or PtdCho at 1.2 mmol/L reduced the expression levels of NPC1L1 protein to 21 or 22%, respectively, and its mRNA to 9 or 31% of that in the control group (p < 0.05). Moreover, there was a general inhibitory effect of egg-yolk PtdCho and CerPCho on the mRNA levels of SREBP-1, and SREBP-2. These results suggest that the inhibitory effect of egg yolk CerPCho and PtdCho on cholesterol transport might be due to their interference with the physicochemical properties of micelles and their regulations on the expression of the NPC1L1 gene. PMID- 29569243 TI - Dietary High-Oleic Acid Soybean Oil Dose Dependently Attenuates Egg Yolk Content of n-3 Polyunsaturated Fatty Acids in Laying Hens Fed Supplemental Flaxseed Oil. AB - Chickens can hepatically synthesize eicosapentaenoic acid (20:5 n-3) and docosahexaenoic acid (22:6 n-3) from alpha-linolenic acid (ALA; 18:3 n-3); however, the process is inefficient and competitively inhibited by dietary linoleic acid (LNA; 18:2 n-6). In the present study, the influence of dietary high-oleic acid (OLA; 18:1 n-9) soybean oil (HOSO) on egg and tissue deposition of ALA and n-3 polyunsaturated fatty acids (PUFA) synthesized from dietary ALA was investigated in laying hens fed a reduced-LNA base diet supplemented with high-ALA flaxseed oil (FLAX). We hypothesized that reducing the dietary level of LNA would promote greater hepatic conversion of ALA to very long-chain (VLC; >20C) n-3 PUFA, while supplemental dietary HOSO would simultaneously further enrich eggs with OLA without influencing egg n-3 PUFA contents. Nine 51-week-old hens each were fed 0, 10, 20, or 40 g HOSO/kg diet for 12 weeks. Within each group, supplemental dietary FLAX was increased every 3 weeks from 0 to 10 to 20 to 40 g/kg diet. Compared to controls, dietary FLAX maximally enriched the total n-3 and VLC n-3 PUFA contents in egg yolk by 9.4-fold and 2.2-fold, respectively, while feeding hens 40 g HOSO/kg diet maximally attenuated the yolk deposition of ALA, VLC n-3 PUFA, and total n-3 PUFA by 37, 15, and 32%, respectively. These results suggest that dietary OLA is not neutral with regard to the overall process by which dietary ALA is absorbed, metabolized, and deposited into egg yolk, either intact or in the form of longer-chain/more unsaturated n-3 PUFA derivatives. PMID- 29569244 TI - Maternal and perinatal outcomes in pregnant women with suspected Ebola virus disease in Sierra Leone, 2014. AB - OBJECTIVE: To describe maternal and perinatal outcomes among pregnant women with suspected Ebola virus disease (EVD) in Sierra Leone. METHODS: Observational investigation of maternal and perinatal outcomes among pregnant women with suspected EVD from five districts in Sierra Leone from June to December 2014. Suspected cases were ill pregnant women with symptoms suggestive of EVD or relevant exposures who were tested for EVD. Case frequencies and odds ratios were calculated to compare patient characteristics and outcomes by EVD status. RESULTS: There were 192 suspected cases: 67 (34.9%) EVD-positive, 118 (61.5%) EVD negative, and 7 (3.6%) EVD status unknown. Women with EVD had increased odds of death (OR 10.22; 95% CI, 4.87-21.46) and spontaneous abortion (OR 4.93; 95% CI, 1.79-13.55) compared with those without EVD. Women without EVD had a high frequency of death (30.2%) and stillbirths (65.9%). One of 14 neonates born following EVD-negative and five of six neonates born following EVD-positive pregnancies died. CONCLUSION: EVD-positive and EVD-negative women with suspected EVD had poor outcomes, highlighting the need for increased attention and resources focused on maternal and perinatal health during an urgent public health response. Capturing pregnancy status in nationwide surveillance of EVD can help improve understanding of disease burden and design effective interventions. PMID- 29569245 TI - Contrasting drivers and trends of coniferous and deciduous tree growth in interior Alaska. AB - The boreal biome represents approximately one third of the world's forested area and plays an important role in global biogeochemical and energy cycles. Numerous studies in boreal Alaska have concluded that growth of black and white spruce is declining as a result of temperature-induced drought stress. The combined evidence of declining spruce growth and changes in the fire regime that favor establishment of deciduous tree species has led some investigators to suggest the region may be transitioning from dominance by spruce to dominance by deciduous forests and/or grasslands. Although spruce growth trends have been extensively investigated, few studies have evaluated long-term radial growth trends of the dominant deciduous species (Alaska paper birch and trembling aspen) and their sensitivity to moisture availability. We used a large and spatially extensive sample of tree cores from interior Alaska to compare long-term growth trends among contrasting tree species (white and black spruce vs. birch and aspen). All species showed a growth peak in the mid-1940s, although growth following the peak varied strongly across species. Following an initial decline from the peak, growth of white spruce showed little evidence of a trend, while black spruce and birch growth showed slight growth declines from ~1970 to present. Aspen growth was much more variable than the other species and showed a steep decline from ~1970 to present. Growth of birch, black and white spruce was sensitive to moisture availability throughout most of the tree-ring chronologies, as evidenced by negative correlations with air temperature and positive correlations with precipitation. However, a positive correlation between previous July precipitation and aspen growth disappeared in recent decades, corresponding with a rise in the population of the aspen leaf miner (Phyllocnistis populiella), an herbivorous moth, which may have driven growth to a level not seen since the early 20th century. Our results provide important historical context for recent growth and raise questions regarding competitive interactions among the dominant tree species and exchanges of carbon and energy in the warming climate of interior Alaska. PMID- 29569247 TI - Heparin-binding protein as a biomarker of post-injury sepsis in trauma patients. AB - BACKGROUND: Heparin-binding protein (HBP) is a neutrophil-derived protein advocated as a biomarker in sepsis. We evaluated plasma HBP as a predictor of post-injury sepsis in trauma patients. METHODS: Ninety-seven trauma patients were studied during the first week of intensive care. Injury-related data were collected and clinical parameters registered daily. Plasma HBP was sampled on day 1, 3 and 5 after trauma and evaluated for associations with injury-related parameters and sepsis. The predictive properties of HBP were compared to C reactive protein (CRP) and white blood cell count (WBC). RESULTS: Median Injury Severity Score was 33, one-third of the trauma patients received massive transfusion and a quarter was in shock on arrival. Overall 30-day mortality was 8%. Plasma HBP was significantly higher in severely injured patients and associated with shock on arrival, massive transfusions and organ failure. Septic patients had higher levels of HBP only on day 5. When evaluated for prediction of onset of sepsis during the two following days after plasma sampling by receiver operating characteristic (ROC) analyses, areas under the curves were non significant for all time points. Similar patterns were seen for CRP and WBC. CONCLUSION: In trauma patients, HBP levels are related to severity of injury and organ dysfunction. Heparin-binding protein was weakly associated with sepsis and only at the later stage of the observation period of 1 week. Moreover, HBP showed poor discriminatory properties as an early biomarker of post-injury sepsis. Trauma-induced inflammation during the post-injury phase may blunt the sepsis predictive performance of HBP. PMID- 29569246 TI - Expansion of airway basal epithelial cells from primary human non-small cell lung cancer tumors. AB - Pre-clinical non-small cell lung cancer (NSCLC) models are poorly representative of the considerable inter- and intra-tumor heterogeneity of the disease in patients. Primary cell-based in vitro models of NSCLC are therefore desirable for novel therapy development and personalized cancer medicine. Methods have been described to generate rapidly proliferating epithelial cell cultures from multiple human epithelia using 3T3-J2 feeder cell culture in the presence of Y 27632, a RHO-associated protein kinase (ROCK) inhibitor, in what are known as "conditional reprograming conditions" (CRC) or 3T3 + Y. In some cancer studies, variations of this methodology have allowed primary tumor cell expansion across a number of cancer types but other studies have demonstrated the preferential expansion of normal epithelial cells from tumors in such conditions. Here, we report our experience regarding the derivation of primary NSCLC cell cultures from 12 lung adenocarcinoma patients enrolled in the Tracking Cancer Evolution through Therapy (TRACERx) clinical study and discuss these in the context of improving the success rate for in vitro cultivation of cells from NSCLC tumors. PMID- 29569248 TI - Probing the molecular regulation of lipopolysaccharide stress in piglet liver by comparative proteomics analysis. AB - Lipopolysaccharide (LPS) can induce inflammatory responses in piglets, causing immunological stress and tissue damage. However, chronic LPS infection may lead to LPS-induced immunological stress resistance. The molecular mechanisms underlying LPS stress have not been fully elucidated. Here, we conducted a global comparative proteomics analysis to investigate the molecular regulation of LPS stress using an immunological stress model of weaned piglets. A shotgun-based SWATH-MS workflow was used for global proteomes of the piglet livers after 15-day LPS treatment. Out of 3700 quantified proteins, 93 proteins showed differential changes under LPS stress. Bioinformatics analysis indicated that the differentially expressed proteins were mainly involved in inflammatory response, oxidation-redox processes and defense reactions, and were enriched in a phagosome pathway. Several key proteins associated with oxidative stress (SOD2), inflammation response (STEAP4 and S100 family) and the phagosome pathway were verified by activity and targeted-MS analyses. The observed responses appear to mitigate hepatic damage due to excessive oxidative stress, inflammation, and repression of the phagosome pathway. Our results reveal that an increased STEAP4 expression in piglets appears involved in cellular regulation by LPS stress and subsequent immunological stress resistance. This study sheds new light on the mechanism of prevention and relieving injury by LPS-induced immune responses. PMID- 29569249 TI - Effect of solvent on the extraction of phenolic compounds and antioxidant capacity of hazelnut kernel. AB - Hazelnut kernel phenolic compounds were recovered applying two different extraction approaches, namely ultrasound-assisted solid/liquid extraction (UA SLE) and solid-phase extraction (SPE). Different solvents were tested evaluating total phenolic compounds and total flavonoids contents together to antioxidant activity. The optimum extraction conditions, in terms of the highest value of total phenolic compounds extracted together to other parameters like simplicity and cost were selected for method validation and individual phenolic compounds analysis. The UA-SLE protocol performed using 0.1 g of defatted sample and 15 mL of extraction solvent (1 mL methanol/1 mL water/8 mL methanol 0.1% formic acid/5 mL acetonitrile) was selected. The analysis of hazelnut kernel individual phenolic compounds was obtained by HPLC coupled with DAD and MS detections. Quantitative analysis was performed using a mixture of six phenolic compounds belonging to phenolic classes' representative of hazelnut. Then, the method was fully validated and the resulting RSD% values for retention time repeatability were below 1%. A good linearity was obtained giving R2 no lower than 0.997.The accuracy of the extraction method was also assessed. Finally, the method was applied to the analysis of phenolic compounds in three different hazelnut kernel varieties observing a similar qualitative profile with differences in the quantity of detected compounds. PMID- 29569250 TI - Impact of upper respiratory tract infections on perioperative outcomes of children undergoing therapeutic cardiac catheterisation. AB - BACKGROUND: Recent upper respiratory tract infection (URI) is associated with increased incidence of perioperative complications in children undergoing open heart surgery. As a result, surgery is often postponed. However, the effect of recent URI on the incidence of perioperative complications in children undergoing therapeutic cardiac catheterisation is unknown. We investigated the perioperative outcomes of congenital heart disease (CHD) children with recent URI who underwent elective therapeutic catheterisation. METHODS: We prospectively included children treated for CHD. Before surgery, parents or legal guardians were interviewed to complete a questionnaire on the child's demographics, history of asthma and passive smoking, and URI symptoms. Recorded perioperative respiratory adverse events (PRAEs) included laryngospasm, bronchospasm, breath holding, oxygen desaturation, and severe cough. Information on postoperative dysphoria, fever, copious sputum, and vomiting was obtained by telephone 24 h after surgery. RESULTS: Of 363 included children, 169 had recently (within 2 weeks) had a URI. The URI did not affect the incidence of laryngospasm, bronchospasm, breath holding, fever, or vomiting. The incidence of desaturation, severe cough, dysphoria, and copious sputum were significantly increased. Independent risk factors for PRAEs in children with a recent URI included age, passive smoking, and presence of rhinorrhoea or moist cough. The lengths of stay in the hospital and intensive care unit were not significantly different between groups. CONCLUSION: Although recent URI increased the incidence of PRAEs in children undergoing therapeutic cardiac catheterisation, most CHD patients with recent URI can undergo elective therapeutic cardiac catheterisation without serious adverse events or prolonged hospitalisation. PMID- 29569251 TI - Prenatal triptan exposure and neurodevelopmental outcomes in 5-year-old children: Follow-up from the Norwegian Mother and Child Cohort Study. AB - BACKGROUND: Triptans are commonly used to treat migraine headaches, but data on the long-term safety of these medications during pregnancy are sparse. Triptans have a biologically plausible mechanism for effects on the fetal brain through binding to 5-HT1 -receptors, and previous studies show increased risks of externalising behaviour problems in toddlers exposed to triptans during pregnancy. METHODS: We included 3784 children in the Norwegian Mother and Child Cohort Study, whose mothers returned the 5-year-questionnaire and reported a history of migraine or triptan use; 353 (9.3%) mothers reported use of triptans during pregnancy, 1509 (39.9%) reported migraine during pregnancy but no triptan use, and 1922 (50.8%) had migraine prior to pregnancy only. We used linear and log-binomial models with inverse probability weights to examine the association between prenatal triptan exposure and internalising and externalising behaviour, communication, and temperament in 5-year-old children. RESULTS: Triptan-exposed children scored higher on the sociability trait than unexposed children of mothers with migraine (beta 1.66, 95% confidence interval [0.30, 3.02]). We found no other differences in temperament, or increased risk of behaviour or communication problems. CONCLUSIONS: Contrary to results from previous studies in younger children, we found no increased risk of externalising behaviour problems in 5-year-old children exposed to triptans in fetal life. Triptan-exposed children did have slightly more sociable temperaments, but the clinical meaning of this finding is uncertain. PMID- 29569252 TI - The clinical features in Chinese patients with PRNP D178N mutation. AB - BACKGROUND AND PURPOSE: Fatal familial insomnia (FFI) is an autosomal dominant disease due to the D178N mutation of PRNP gene coupling with homozygous methionine (Met) at codon 129. It is generally considered that D178N mutation cases with 129 M/M homozygotes present as FFI, and 129 V/V as genetic CJD. However, the frequency of 129 Met alleles in Chinese population is much higher than that in Caucasians. This study aims to investigate the clinical features and genetic characteristics of Chinese D178N mutants in this genetic context. METHODS: We reviewed the clinical and genetic features of seven D178N patients. The clinical data, genetic data, electroencephalogram (EEG), brain magnetic resonance imaging (MRI), polysomnography (PSG), CSF 14-3-3 protein examinations of the seven patients were analyzed. RESULTS: The genotypes at codon 129 were all M/M. Four of the seven cases reported positive family history. Four patients were more likely the CJD phenotype and three were FFI phenotype according to the core clinical features. No major differences were found on the EEG, CSF 14-3-3 protein, and PSG presentations between this study and western studies. Novel neuroimaging findings were two patients had typical neuroimaging abnormalities of CJD and frontotemporal dementia, respectively. CONCLUSIONS: Unlike the western populations, the diverse phenotypical presentations of D178N mutants were not simply determined by the 129 genotypes in Chinese. The underlying modifying factors for phenotypical variations warrant further investigations. For those with atypical clinical and imaging features, genetic testing was important for final diagnosis. PMID- 29569253 TI - Detection and management of atrial fibrillation after cryptogenic stroke or embolic stroke of undetermined source. AB - Cryptogenic stroke (CS) and embolic stroke of unknown source (ESUS) represent a major challenge to healthcare systems worldwide. Atrial fibrillation (AF) is commonly found after CS or ESUS. Independent of the mechanism of the index CS or ESUS, detection of AF in these patients offers the opportunity to reduce the risk of stroke recurrence by prescribing an anticoagulant instead of aspirin. The detection of AF may be pursued with different monitoring strategies. Comparison of monitoring strategies should take into account that AF detection rates reported in published studies, and then pooled in meta-analyses, are not only a function of the monitoring strategy itself, but also depend on patient-related, device-related, and study design-related factors. Once AF is found, the decision to anticoagulate a patient should be made on the basis of AF burden and the baseline risk of the patient. Empirical anticoagulation in patients with ESUS and no evidence of AF is an intriguing but still-unproven strategy and therefore should not be adopted outside of randomized clinical trials.

PMID- 29569254 TI - Stem-cell therapy in ST-segment elevation myocardial infarction with reduced ejection fraction: A multicenter, double-blind randomized trial. AB - BACKGROUND: Left ventricular ejection fraction (LVEF) is a major determinant of long-term prognosis after ST-segment elevation myocardial infarction (STEMI). STEMI patients with reduced LVEF have a poor prognosis, despite successful reperfusion and the use of renin-angiotensin-aldosterone inhibitors. HYPOTHESIS: Intracoronary infusion of bone marrow-derived mononuclear cells (BMMC) may improve LVEF in STEMI patients successfully reperfused. METHODS: The main inclusion criteria for this double-blind, randomized, multicenter study were patient age 30 to 80 years, LVEF <=50%, successful angioplasty of infarct-related artery, and regional dysfunction in the infarct-related area analyzed before cell injection. Cardiac magnetic resonance imaging was used to assess LVEF, left ventricular volumes, and infarct size at 7 to 9 days and 6 months post-myocardial infarction. RESULTS: One hundred and twenty-one patients were included (66 patients in the BMMC group and 55 patients in the placebo group). The primary endpoint, mean LVEF, was similar between both groups at baseline (44.63% +/- 10.74% vs 42.23% +/- 10.33%; P = 0.21) and at 6 months (44.74% +/- 12.95 % vs 43.50 +/- 12.43%; P = 0.59). The groups were also similar regarding the difference between baseline and 6 months (0.11% +/- 8.5% vs 1.27% +/- 8.93%; P = 0.46). Other parameters of left ventricular remodeling, such as systolic and diastolic volumes, as well as infarct size, were also similar between groups. CONCLUSIONS: In this randomized, multicenter, double-blind trial, BMMC intracoronary infusion did not improve left ventricular remodeling or decrease infarct size. PMID- 29569256 TI - Job strain associated with increases in ambulatory blood and pulse pressure during and after work hours among female hotel room cleaners. AB - BACKGROUND: Previously documented elevated hypertension rates among Las Vegas hotel room cleaners are hypothesized to be associated with job strain. METHODS: Job strain was assessed by questionnaire. Ambulatory blood pressure (ABP) was recorded among 419 female cleaners from five hotels during 18 waking hours. Multiple linear regression models assessed associations of job strain with ABP and pulse pressure for 18-h, work hours, and after work hours. RESULTS: Higher job strain was associated with increased 18-h systolic ABP, after work hours systolic ABP, and ambulatory pulse pressure. Dependents at home but not social support at work attenuated effects. Among hypertensive workers, job strain effects were partially buffered by anti-hypertensive medication. CONCLUSIONS: High job strain is positively associated with blood pressure among female hotel workers suggesting potential for primary prevention at work. Work organizational changes, stress management, and active ABP surveillance and hypertension management should be considered for integrated intervention programs. PMID- 29569257 TI - Production of d-mannose from d-glucose by co-expression of d-glucose isomerase and d-lyxose isomerase in Escherichia coli. AB - BACKGROUND: d-Mannose is not only the epimer of d-glucose at the C-2 position, but also the aldose isomer of d-fructose. Because of its physiological properties and health benefits, d-mannose has attracted public interest. It has been confirmed that d-mannose has broad applications in food, cosmetics, and pharmaceutical industries. According to the Izumoring strategy, d-glucose isomerase (d-GI) and d-lyxose isomerase (d-LI) play important roles in the conversions of d-fructose from d-glucose and of d-mannose from d-fructose respectively. In this study, a one-step enzyme process of d-mannose production from d-glucose has been constructed by co-expression of the d-GI from Acidothermus cellulolyticus and d-LI from Thermosediminibacter oceani in Escherichia coli BL21(DE3) cells. RESULTS: The co-expression system exhibits maximum activity at pH 6.5 and 65 degrees C with Co2+ supplement. It is relatively thermostable at less than 65 degrees C. When the reaction reaches equilibrium, the ratio of d-glucose, d-fructose, and d-mannose is approximately 34 : 49.6 : 16.4. By using this co-expression system, about 60.0 g L-1 d-mannose is obtained from 400 g L-1 d-glucose in 8 h. CONCLUSION: This co-expression of d GI and d-LI system provides a novel and efficient approach for d-mannose production. (c) 2018 Society of Chemical Industry. PMID- 29569258 TI - Primary cutaneous ganglioneuroma: anatomico-clinical study of 4 cases with focus on Merkel cells. AB - Cutaneous ganglioneuromas (CGNs) are exceptional. We aim to describe the anatomico-clinical profile of primary CGN and report 4 cases. Patients were 2 men and 2 women aged 53 to 76 years, who had flesh-colored nodules on the back, associated with adjacent keratotic changes, that is, epidermal nevus (1 case) or seborrheic keratosis (3 cases). Histopathology showed ganglion cells within a proliferation of Schwann cells. The epidermis was acanthotic, associated with sebaceous induction in 2 cases, with follicular hyperplasia as in fibroepithelial tumors (1 case) or with tricholemmoma (2 cases). Cytokeratin-20 immunostaining showed Merkel cells in the epidermis. A higher density of Merkel cells was observed in BerEP4+ follicular structures. Along with 16 published cases, our study indicates that a nodule associated with seborrheic keratosis on the back may represent a CGN, a complex mesenchymal and epidermal/follicular lesion of neuroectodermal lineage, associating neuronal proliferation and Merkel cell hyperplasia with follicular induction. PMID- 29569259 TI - Varicocele is the root cause of BPH: Destruction of the valves in the spermatic veins produces elevated pressure which diverts undiluted testosterone directly from the testes to the prostate. AB - In varicocele, there is venous flow of free testosterone (FT) directly from the testes into the prostate. Intraprostatic FT accelerates prostate cell production and prolongs cell lifespan, leading to the development of BPH. We show that in a large group of patients presenting with BPH, bilateral varicocele is found in all patients. A total of 901 patients being treated for BPH were evaluated for varicocele. Three diagnostic methods were used as follows: physical examination, colour flow Doppler ultrasound and contact liquid crystal thermography. Bilateral varicocele was found in all 901 patients by at least one of three diagnostic methods. Of those subsequently treated by sclerotherapy, prostate volume was reduced in more than 80%, with prostate symptoms improved. A straightforward pathophysiologic connection exists between bilateral varicocele and BPH. The failure of the one-way valves in the internal spermatic veins leads to a cascade of phenomena that are unique to humans, a result of upright posture. The prostate is subjected to an anomalous venous supply of undiluted, bioactive free testosterone. FT, the obligate control hormone of prostate cells, reaches the prostate directly via the venous drainage system in high concentrations, accelerating the rate of cell production and lengthening cell lifespan, resulting in BPH. PMID- 29569260 TI - Down-regulation of microRNA-375 regulates adipokines and inhibits inflammatory cytokines by targeting AdipoR2 in non-alcoholic fatty liver disease. AB - Non-alcoholic fatty liver disease (NAFLD) has been considered as a multi factorial metabolic syndrome. MicroRNA-375 (MiR-375) was significantly up regulated in serum of NAFLD patients and the role of miR-375 was addressed as a putative biomarker of NAFLD progression. However, the specific function of miR 375 in the progression of NAFLD is still unclear and the molecular mechanisms underlying NAFLD have yet to be elucidated. Our study aimed at investigating the regulatory role of miR-375 in the molecular mechanisms of the pathogenic progression of NAFLD and to find out whether miR-375 regulates the expression level of adipokines and inflammatory cytokines in NAFLD. We found that miR-375 expression was increased in the serum of high fat diet (HFD)-feeding mice comparing to that in healthy controls, whereas the expression of Adiponectin receptor 2 (AdipoR2) was decreased in mice fed with HFD. Moreover, inhibiton of miR-375 up-regulated the expression of Adiponectin, inhibited the lipid accumulation and down-regulated both the level of Leptin and inflammatory cytokines including tumour necrosis factor (TNF)-alpha and interleukin (IL)-6 in palmiticacid (PA)-induced human hepatocellular carcinoma HepG2 cells. In addition, we also found that AdipoR2 was a target of miR-375 by binding directly to the 3'UTR of it. Of note, the reduced level of TNF-alpha, IL-6 as well as Leptin and the production of Adiponectin by miR-375 inhibitors was significantly reversed by silencing of AdipoR2 in PA-induced HepG2 cells. Our findings bring new insight into understanding the complex mechanisms underlying the pathogenesis of NAFLD and provide evidence that miR-375 might represent a novel therapeutic target for NAFLD. PMID- 29569261 TI - Activity-guided isolation of phase II enzyme inducers from buckwheat flour methanolic extracts. AB - BACKGROUND: Buckwheat is an important alternative crop and a raw material for functional food formulation. Phase II detoxification proteins/enzymes provide cytoprotective roles against oxidative stress and inflammation originating from various stressors. We aimed to identify and characterize potential phase II enzyme inducers from methanolic extracts of buckwheat flour, using an activity guided fractionation based on the induction of quinone reductase (QR) (EC 1.6.5.2) in Hepa 1c1c7 cells. RESULTS: We isolated the QR inducers N-trans feruloyltyramine (I), syringic acid (II), quercetin (III) and myricetin (IV). The relative QR-inducing ability, as well as the concentration required to double QR specific activity (CD values, in parentheses), decreased in the order: quercetin (3.0 umol L-1 ) > N-trans-feruloyltyramine (24 umol L-1 ) > myricetin (58 umol L 1 ) > syringic acid (5.4 mmol L-1 ). Quercetin and N-trans-feruloyltyramine exhibited the greatest extent of QR induction of an approximately four-fold maximum induction and these compounds also exhibited the greatest values for the ratio of IC50 (i.e. level to reduce viability by 50%): CD values of 11 and > 8.3, respectively, among the four QR inducers isolated. Isobologram analyses for binary combinations of compounds I-IV revealed primarily antagonistic interactions for QR induction. CONCLUSION: These findings add to our understanding of the nutraceutical potential of buckwheat as a chemoprophylactic dietary component. (c) 2018 Society of Chemical Industry. PMID- 29569262 TI - Application of the RAND-UCLA Appropriateness Methodology to a Large Multidisciplinary Stakeholder Group Evaluating the Validity and Feasibility of Patient-Centered Standards in Geriatric Surgery. AB - OBJECTIVES: To explore (1) differences in validity and feasibility ratings for geriatric surgical standards across a diverse stakeholder group (surgeons vs. nonsurgeons, health care providers vs. nonproviders, including patient-family, advocacy, and regulatory agencies); (2) whether three multidisciplinary discussion subgroups would reach similar conclusions. DATA SOURCE/STUDY SETTING: Primary data (ratings) were reported from 58 stakeholder organizations. STUDY DESIGN: An adaptation of the RAND-UCLA Appropriateness Methodology (RAM) process was conducted in May 2016. DATA COLLECTION/EXTRACTION METHODS: Stakeholders self administered ratings on paper, returned via mail (Round 1) and in-person (Round 2). PRINCIPAL FINDINGS: In Round 1, surgeons rated standards more critically (91.2 percent valid; 64.9 percent feasible) than nonsurgeons (100 percent valid; 87.0 percent feasible) but increased ratings in Round 2 (98.7 percent valid; 90.6 percent feasible), aligning with nonsurgeons (99.7 percent valid; 96.1 percent feasible). Three parallel subgroups rated validity at 96.8 percent (group 1), 100 percent (group 2), and 97.4 percent (group 3). Feasibility ratings were 76.9 percent (group 1), 96.1 percent (group 2), and 92.2 percent (group 3). CONCLUSIONS: There are differences in validity and feasibility ratings by health professions, with surgeons rating standards more critically than nonsurgeons. However, three separate discussion subgroups rated a high proportion (96-100 percent) of standards as valid, indicating the RAM can be successfully applied to a large stakeholder group.

AB - Over the past 10 years, the FDI-Unilever Brush Day & Night partnership has significantly influenced the life of children worldwide through the implementation of school programmes for oral health education and prevention. This article reports the key facts and outcomes of Phase III of the partnership, and announces the launch of Phase IV. During Phase III, the expert advisors of the Brush Day & Night partnership conducted a longitudinal study to evaluate the impact of the '21 Day' programme in almost 8,000 children in 10 countries. Analysis revealed the effectiveness of the 21 Day programme in sustainably educating children to brush their teeth twice a day, with the greatest impact observed in children aged 7-9 years. With the launch of Phase IV, the Brush Day & Night partnership will continue to deliver its oral health school programme for 7 9 year-old children with a strengthened methodology, including randomized sampling and control groups. The scope of the evaluation will be broadened to include oral health-related quality of life indicators, and monitoring of the oral health knowledge of children's parents/carers. PMID- 29569264 TI - Cloning, expression profiling, and acetylation identification of alpha-tubulin N acetyltransferase 1 from Bombyx mori. AB - Alpha-tubulin N-acetyltransferase 1 (ATAT1) is an acetyltransferase specific to alpha-tubulin and performs important functions in many cellular processes. Bombyx mori is an economic insect and also known as a model lepidoptera insect. In this study, we cloned a B. mori ATAT1 gene (BmATAT1) (Gen Bank accession number: XP_004932777.1). BmATAT1 contained an open reading frame (ORF) of 1,065 bp encoding 355 amino acids (aa). Expression profiling of BmATAT1 protein showed that the expression levels of BmATAT1 at different developmental stages and different tissues in fifth-instar larvae differ. BmATAT1 was highly expressed at the egg stage and in the head of the fifth-instar larvae. Subcellular localization showed that BmATAT1 was distributed in the cytoplasm and nucleus. Furthermore, BmATAT1 may lead to time-dependent induction of cell cycle arrest in the G2/M phase by flow cytometry analysis. Interestingly, using site-specific mutation, immunoprecipitation, and Western blotting, we further found a BmATAT1 acetylated site at K156, suggesting that this acetyltransferase could be regulated by acetylation itself. PMID- 29569265 TI - Three-dimensional speckle tracking echocardiography-derived left atrial deformation analysis in acromegaly (Results from the MAGYAR-Path Study). AB - INTRODUCTION: Acromegaly is a chronic and disfiguring hormonal disease caused by a benign growth hormone-secreting pituitary adenoma in most of the cases. The objective of this study was to investigate three-dimensional (3D) speckle tracking echocardiography (3DSTE)-derived left atrial (LA) volumetric and functional properties in patients with acromegaly. It was also examined whether the activity of acromegaly is associated with further alterations in these LA parameters. METHODS: A total of 23 patients with acromegaly were involved in this study. Due to inadequate image quality, 4 patients were excluded from the 3DSTE analysis. The mean age of the remaining acromegalic subjects was 58.5 +/- 13.1 years (7 males). The control group consisted of 21 age- and gender-matched healthy subjects (mean age 51.8 +/- 10.3 years, 10 males). RESULTS: Maximum (44.8 +/- 12.7 mL vs 78.7 +/- 25.4 mL, P < .05), minimum (24.1 +/- 9.0 mL vs 44.5 +/- 15.5 mL, P < .05), and preatrial contraction (35.5 +/- 11.2 mL vs 66.0 +/- 22.8 mL, P < .05) LA volumes were significantly different between all acromegaly patients compared with controls. Increased peak global and mean segmental radial and 3D strains and decreased LA circumferential strain (CS) could be detected in all acromegaly patients as compared to healthy subjects. Significant correlation could be detected between insulin-like growth factor 1 (IGF-1) index and peak superior LA-CS (r = .49, P = .05) in acromegaly. CONCLUSION: Acromegaly is associated with increased LA volumes and changes in LA functional properties. PMID- 29569267 TI - Defining the optimal sensory environment in the NICU: an elusive task. PMID- 29569266 TI - A late presentation of congenital cardiac anomaly: Accessory chordae from the left atrium causing severe mitral regurgitation. AB - Mitral regurgitation secondary to accessory mitral valve (MV) chordae of the left atrium is an extremely rare congenital disease. A 85-year-old female (NYHA I-II) was hospitalized for investigations. An echocardiogram showed calcification of the MV with mild stenosis and moderate regurgitation. Transesophageal three dimensional echocardiogram revealed a band-like structure extending from the distal third of the anterior wall of the left atrium to the MV. This accessory chordae determined severe systolic regurgitation and mild mitral stenosis. The patient was referred for consideration of cardiac surgery but was refused for comorbidities and anatomy. Usually aberrant chordae determinant valvulopathies are detected and treated at a much younger age. The delay of the symptoms could be explained in our case with the progressive growth and dilatation of the left atrium causing traction of the aberrant chord resulting in an increase in the leaflet prolapse and regurgitation.

AB - BACKGROUND: Lyme disease (LD) is one of the most common tick-borne diseases caused by several Borrelia species of spirochetes. Ixodes scapularis is responsible for the transmission of LD in the northeastern United States. The rate of infection varies with the duration of tick attachment to the host; however, this information may be unknown. In skin biopsies, it is often difficult to identify spirochetes. Testing of ticks is not routinely performed. Treatment is established by clinical presentation. OBJECTIVE: To test paraffin-embedded I. scapularis ticks for Borrelia by different methods. MATERIALS/METHODS: We examined 20 paraffin-embedded ticks by silver stain, immunohistochemical (IHC) and direct immunofluorescent (DIF) methods and compared the percentage of positivity with DIF results from the Connecticut Agricultural Experiment Station. RESULTS: The results were similar by DIF, which proved to be the most sensitive method, followed by the silver stain and IHC. CONCLUSION: We found that the identification of spirochetes in paraffin-embedded ticks was less difficult than in tissue with a comparable turnaround time to that of a routine biopsy. Timely identification of Borrelia in ticks may influence the clinical management of the patients. PMID- 29569270 TI - Effect of nutritional status on arsenic and smokeless tobacco induced genotoxicity, sperm abnormality and oxidative stress in mice in vivo. AB - BACKGROUND: Recently, high concentrations of arsenic have been documented in ground waters of Southern Assam, India. Indiscriminate smokeless tobacco consumption is a common practice in this region. Correlation between nutritional status and arsenic and smokeless tobacco-induced health effects has not been taken up in humans or other test systems. METHODS: Mice were divided into groups based on protein (casein) content in the diet: High protein (40%), optimum protein (20%), and low protein (5%). Simultaneous chronic exposure (90 days) to arsenic and smokeless tobacco (sadagura) orally was given to evaluate the extent of the cytological and genotoxicological damage. Micronucleus assay and Comet assay of the femur bone marrow cells were conducted. Germ cell toxicity was evaluated by recording the sperm head abnormalities and total sperm count. Cell cycle analysis was performed in femur bone marrow cells using flow cytometer. Hepatic, renal, and intestinal tissues were analyzed for various oxidative stress evaluations. Histological examination of liver and kidney was performed. RESULTS: Notably, high protein diet groups had lower arsenic and sadagura induced genotoxicity, germ cell abnormalities and oxidative stress as compared to optimum protein and low protein diet counterparts. CONCLUSION: Our study indicates that sufficient levels of dietary protein appear to reduce the long-term arsenic and smokeless tobacco-induced toxicity in mice test system, as compared to lower or deficient amount of protein in the diet. This observation has implications and invites further studies especially epidemiological studies in the human population exposed to arsenic in South East Asian countries. Environ. Mol.

AB - The diagnosis of alopecia areata is usually based on clinical manifestations. However, there are several hair and scalp disorders that share similar clinical features with alopecia areata, such as tinea capitis, trichotillomania or traction alopecia. Trichoscopy as a fast, non-invasive and easy-to-perform technique may help to identify subtle details and establish the correct diagnosis. The aim of this review is to present the spectrum of trichoscopic findings in alopecia areata. A systematic review of the published work was performed by searching the PubMed, Scopus and EBSCO databases, complemented by a thorough hand search of reference lists. Of 427 articles retrieved, 30 studies were eligible for quantitative analysis. The reported features of alopecia areata were: yellow dots (6-100% patients), short vellus hairs (34-100%), black dots (0 84%), broken hairs (0-71%) and exclamation mark hairs (12-71%). Tapered hairs (5 81%) were reported in few studies, but a relatively high frequency of this finding in alopecia areata may indicate their important role in the differential diagnosis of hair loss. Rarely reported features, which include upright regrowing hairs (11-96%), pigtail (circle) hairs (4-61%) and Pohl-Pinkus constrictions (2 10%), may also be helpful in the diagnosis of alopecia areata. There is no pathognomonic trichoscopic marker for alopecia areata and the most common trichoscopic features are not the most specific. Therefore, the diagnosis should be based on the coexistence of several trichoscopic findings, not on the presence of a single feature. PMID- 29569272 TI - Anti/genotoxic, longevity inductive, cytotoxic, and clastogenic-related bioactivities of tomato and lycopene. AB - The aim of this study was to evaluate some biological activities of tomato as well as lycopene and to consider a new nutraceutic value for this fruit regarding to the protection against genetic damage and as a chemopreventive agent. Genotoxicity, DNA-protection against hydrogen peroxide, and lifespan properties of tomato and lycopene were assessed through wing spot test and longevity assay using the Drosophila in vivo model. Additionally, chemopreventive activity was investigated through cytotoxicity, DNA-fragmentation comet and annexin V FITC/PI assays using HL60 in vitro model. Results showed that: (i) tomato and lycopene are not genotoxic and protect against H2 O2 -induced damage; (ii) with respect to the lifespan, tomato and lycopene are harmless at the lowest concentration; (iii) tomato is cytotoxic in a dose-dependent manner, but not lycopene; (iv) tomato and lycopene do not induce internucleosomal DNA-fragmentation although they induce significant clastogenic activity at low level in the leukemia cells. To sum up, tomato is a good candidate to be considered as a nutraceutical substance. Furthermore, synergistic action among other components within tomato matrix could be the cause of the health effects observed in this vegetable, which are not fully explained by lycopene. Environ.

PMID- 29569273 TI - The predictive value of global longitudinal strain on clinical outcome in patients with ST-segment elevation myocardial infarction and preserved systolic function. AB - BACKGROUND: Left ventricular ejection fraction (LVEF) is fundamental for risk stratification after ST-segment elevation myocardial infarction (STEMI). However, it lacks discrimination power within normal range. Novel echocardiographic deformation parameters may be of benefit for those with post-MI preserved LVEF. OBJECTIVES: We hypothesized that semiautomated calculation of baseline global longitudinal strain (GLS) can identify high-risk group among patients with LVEF >= 50% following STEMI. METHODS: During the period from January to July 2017, 110 patients with successful reperfusion of STEMI and LVEF >= 50% were prospectively included. Within 48 hours, patients underwent a baseline GLS study with follow-up study at 30 days. The endpoint was a composite of cardiovascular mortality, rehospitalization for heart failure, and urgent revascularization. RESULTS: Mean GLS value changed from -16 +/- 4% at baseline to -12 +/- 4% at 30-day follow-up (P < .001). At 30 days, cardiovascular mortality was reported in 4.5%, 11.8% were rehospitalized due to heart failure, and 5.4% underwent urgent revascularization. ROC curve analysis showed that a cutoff baseline GLS value >-12.65% predicted 30 day MACEs with a sensitivity and specificity of 77.8% and 83.7%, respectively (AUC 0.784, 95% CI 0.646-0.921, P < .001). An adjusted multivariate logistic regression analysis revealed that baseline GLS value >-12.65% to be the only significant independent predictor for occurrence of MACEs (OR 19.54, 95% CI 6.3 61.1, P < .001). CONCLUSION: Early GLS calculation predicts 30-day outcome in patients with preserved LVEF following reperfusion of STEMI. PMID- 29569275 TI - Emotional intelligence and attentional bias for threat-related emotion under stress. AB - Emotional intelligence (EI) can buffer potentially harmful effects of situational and chronic stressors to safeguard psychological wellbeing (e.g., Mikolajczak, Petrides, Coumans & Luminet, ), yet understanding how and when EI operates to promote adaptation remains a research priority. We explored whether EI (both trait and ability) modulated early attentional processing of threat-related emotion under conditions of stress. Using a dot probe paradigm, eye movement (fixation to emotive facial stimuli, relative to neutral) and manual reaction time data were collected from 161 adults aged 18-57 years (mean age = 25.24; SD = 8.81) exposed to either a stressful (failure task) or non-stressful (control) situation. Whilst emotion management ability and trait wellbeing corresponded to avoidance of negative emotion (angry and sad respectively), high trait sociability and emotionality related to a bias for negative emotions. With most effects not restricted to stressful conditions, it is unclear whether EI underscores 'adaptive' processing, which carries implications for school-based social and emotional learning programs. PMID- 29569274 TI - The effects of acetaldehyde exposure on histone modifications and chromatin structure in human lung bronchial epithelial cells. AB - As the primary metabolite of alcohol and the most abundant carcinogen in tobacco smoke, acetaldehyde is linked to a number of human diseases associated with chronic alcohol consumption and smoking including cancers. In addition to direct DNA damage as a result of the formation of acetaldehyde-DNA adducts, acetaldehyde may also indirectly impact proper genome function through the formation of protein adducts. Histone proteins are the major component of the chromatin. Post translational histone modifications (PTMs) are critically important for the maintenance of genetic and epigenetic stability. However, little is known about how acetaldehyde-histone adducts affect histone modifications and chromatin structure. The results of protein carbonyl assays suggest that acetaldehyde forms adducts with histone proteins in human bronchial epithelial BEAS-2B cells. The level of acetylation for N-terminal tails of cytosolic histones H3 and H4, an important modification for histone nuclear import and chromatin assembly, is significantly downregulated following acetaldehyde exposure in BEAS-2B cells, possibly due to the formation of histone adducts and/or the decrease in the expression of histone acetyltransferases. Notably, the level of nucleosomal histones in the chromatin fraction and at most of the genomic loci we tested are low in acetaldehyde-treated cells as compared with the control cells, which is suggestive of inhibition of chromatin assembly. Moreover, acetaldehyde exposure perturbs chromatin structure as evidenced by the increase in general chromatin accessibility and the decrease in nucleosome occupancy at genomic loci following acetaldehyde treatment. Our results indicate that regulation of histone modifications and chromatin accessibility may play important roles in acetaldehyde-induced pathogenesis. Environ. Mol. Mutagen. 59:375-385, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29569276 TI - Is desiccation tolerance and avoidance reflected in xylem and phloem anatomy of two coexisting arid-zone coniferous trees? AB - Plants close their stomata during drought to avoid excessive water loss, but species differ in respect to the drought severity at which stomata close. The stomatal closure point is related to xylem anatomy and vulnerability to embolism, but it also has implications for phloem transport and possibly phloem anatomy to allow sugar transport at low water potentials. Desiccation-tolerant plants that close their stomata at severe drought should have smaller xylem conduits and/or fewer and smaller interconduit pits to reduce vulnerability to embolism but more phloem tissue and larger phloem conduits compared with plants that avoid desiccation. These anatomical differences could be expected to increase in response to long-term reduction in precipitation. To test these hypotheses, we used tridimensional synchroton X-ray microtomograph and light microscope imaging of combined xylem and phloem tissues of 2 coniferous species: one-seed juniper (Juniperus monosperma) and pinon pine (Pinus edulis) subjected to precipitation manipulation treatments. These species show different xylem vulnerability to embolism, contrasting desiccation tolerance, and stomatal closure points. Our results support the hypothesis that desiccation tolerant plants require higher phloem transport capacity than desiccation avoiding plants, but this can be gained through various anatomical adaptations in addition to changing conduit or tissue size. PMID- 29569277 TI - Use of genetic, climatic, and microbiological data to inform reintroduction of a regionally extinct butterfly. AB - Species reintroductions are increasingly used as means of mitigating biodiversity loss. Besides habitat quality at the site targeted for reintroduction, the choice of source population can be critical for success. The butterfly Melanargia russiae (Esper's marbled white) was extirpated from Hungary over 100 years ago, and a reintroduction program has recently been approved. We used museum specimens of this butterfly, mitochondrial DNA data (mtDNA), endosymbiont screening, and climatic-similarity analyses to determine which extant populations should be used for its reintroduction. The species displayed 2 main mtDNA lineages across its range: 1 restricted to Iberia and southern France (Iberian lineage) and another found throughout the rest of its range (Eurasian lineage). These 2 lineages possessed highly divergent wsp alleles of the bacterial endosymbiont Wolbachia. The century-old Hungarian specimens represented an endemic haplotype belonging to the Eurasian lineage, differing by one mutation from the Balkan and eastern European populations. The Hungarian populations of M. russiae occurred in areas with a colder and drier climate relative to most sites with extant known populations. Our results suggest the populations used for reintroduction to Hungary should belong to the Eurasian lineage, preferably from eastern Ukraine (genetically close and living in areas with the highest climatic similarity). Materials stored in museum collections can provide unique opportunities to document historical genetic diversity and help direct conservation. PMID- 29569278 TI - Lenalidomide treatment of myelodysplastic syndromes with chromosome 5q deletion: Results from the National Registry of the Italian Drug Agency. AB - OBJECTIVE: The most typical cytogenetic aberration in myelodysplastic syndromes is del(5q), which, when isolated, is associated with refractory anaemia and good prognosis. Based on high rates of erythroid response and transfusion independence, Lenalidomide (LEN) became the standard treatment. This multi-centre study was designed to supplement Italian Registry data on LEN by addressing prescription, administration appropriateness, haematological and cytogenetic responses and disease evolution. METHODS: MORE study was an observational, non interventional, multi-centre, retrospective and prospective study. Cases were recruited from 45 Haematological Centres throughout Italy. Data were collected from the Italian National Registry for Lenalidomide administration and supplemented by a MORE data form. RESULTS: Data from 190/213 patients were analysed. In all, 149 had been diagnosed by conventional cytogenetics (GROUP A) and 41 only by FISH (GROUP B). Overall erythroid response was obtained in 92.8% of cases. Overall cytogenetic remission was achieved in 22.6% of cases. Disease progression occurred in 15.6% of cases. Clonal cytogenetic evolution characterised progression to AML but not to higher risk MDS. CONCLUSIONS: Erythroid response to Lenalidomide was similar in MDS with isolated del(5q) and with del(5q) plus one anomaly. Progression to AML or higher risk MDS showed different cytogenetic features. PMID- 29569279 TI - Role of prephase treatment prior to definitive chemotherapy in patients with diffuse large B-cell lymphoma. AB - BACKGROUND: During the treatment of diffuse large B-cell lymphoma (DLBCL) patients, treatment-related toxicities are higher in the initial phase of treatment (First cycle effect). Toxicities can be tumor lysis syndrome, deterioration in performance status, febrile neutropenia, and rarely mortality. Prephase treatment before definitive chemotherapy is used in European countries to alleviate these toxicities. METHODS: This was a non-randomized study carried out with the aim to evaluate the role of prephase treatment given prior to definitive chemotherapy in newly diagnosed DLBCL patients. Patients were divided into 2 cohorts "prephase cohort" and "non-prephase cohort." Prephase cohort received prephase treatment consisting of vincristine (1 mg) on -6th day and prednisolone 100 mg daily for 7 days (-6th day to day 0). Prephase treatment was followed by CHOP/R-CHOP chemotherapy on day 1. Non-prephase cohort received chemotherapy without prephase. Both groups were followed up for 30 days post first cycle chemotherapy. RESULTS: A total of 100 patients with DLBCL (50 in each cohort) were enrolled. There was a significant improvement in performance status of the patients who received prephase. A majority of 92% patients attained ECOG performance status of either 0 or 1 before starting chemotherapy in the prephase cohort. Febrile neutropenia was lower (16%) in the prephase cohort as compared with the non-prephase cohort (34%; P = .037). CONCLUSION: Prephase treatment prior to definitive chemotherapy (CHOP +/- Rituximab) improves the performance status and decreases first cycle effect in DLBCL patients. PMID- 29569280 TI - Developing High-Performance Lithium Metal Anode in Liquid Electrolytes: Challenges and Progress. AB - Lithium metal anodes are potentially key for next-generation energy-dense batteries because of the extremely high capacity and the ultralow redox potential. However, notorious safety concerns of Li metal in liquid electrolytes have significantly retarded its commercialization: on one hand, lithium metal morphological instabilities (LMI) can cause cell shorting and even explosion; on the other hand, breaking of the grown Li arms induces the so-called "dead Li"; furthermore, the continuous consumption of the liquid electrolyte and cycleable lithium also shortens cell life. The research community has been seeking new strategies to protect Li metal anodes and significant progress has been made in the last decade. Here, an overview of the fundamental understandings of solid electrolyte interphase (SEI) formation, conceptual models, and advanced real-time characterizations of LMI are presented. Instructed by the conceptual models, strategies including increasing the donatable fluorine concentration (DFC) in liquid to enrich LiF component in SEI, increasing salt concentration (ionic strength) and sacrificial electrolyte additives, building artificial SEI to boost self-healing of natural SEI, and 3D electrode frameworks to reduce current density and delay Sand's extinction are summarized. Practical challenges in competing with graphite and silicon anodes are outlined. PMID- 29569281 TI - Ruptured mitral valve aneurysm: A devastating complication of aortic valve endocarditis. AB - Mitral valve aneurysm is a rare clinical entity that is mostly resulted from infective endocarditis, in particular, aortic valve endocarditis. Once mitral valve aneurysm ruptures and severe mitral regurgitation and hemodynamic instability develop, prompt surgery should be considered. Here we report a patient with ruptured mitral valve aneurysm associated with native aortic valve endocarditis that was improved after a successful mitral and aortic valve replacement surgery associated with antibiotic therapy for 6 weeks. PMID- 29569282 TI - Fractional flow reserve-CT assessment of coronary stenosis. AB - Coronary computed tomography angiography (CCTA) has been an established noninvasive method for detection of coronary artery disease (CAD). Although CCTA has had a high sensitivity and negative predictive value for CAD detection, specificity for obstructive CAD has been relatively low, partly due to coronary calcium, imaging artifacts, and other factors leading to an overestimation of stenosis severity. A relatively new noninvasive method of calculation of fractional flow reserve (FFR) using CCTA (FFRCT ) data has been developed. This noninvasive method yields similar results to invasive FFR measurement, improving specificity for noninvasively detecting lesion-specific ischemia thus helping guide revascularization.

AB - The implementation of water splitting systems, powered by sustainable energy resources, appears to be an attractive strategy for producing high-purity H2 in the absence of the release of carbon dioxide (CO2 ). However, the high cost, impractical operating conditions, and unsatisfactory efficiency and stability of conventional methods restrain their large-scale development. Seawater covers 70% of the Earth's surface and is one of the most abundant natural resources on the planet. New research is looking into the possibility of using seawater to produce hydrogen through electrolysis and will provide remarkable insight into sustainable H2 production, if successful. Here, guided by density functional theory (DFT) calculations to predict the selectivity of gas-evolving catalysts, a seawater-splitting device equipped with affordable state-of-the-art electrocatalysts composed of earth-abundant elements (Fe, Co, Ni, and Mo) is demonstrated. This device shows excellent durability and specific selectivity toward the oxygen evolution reaction in seawater with near 100% Faradaic efficiency for the production of H2 and O2 . Powered by a single commercial III-V triple-junction photovoltaic cell, the integrated system achieves spontaneous and efficient generation of high-purity H2 and O2 from seawater at neutral pH with a remarkable 17.9% solar-to-hydrogen efficiency. PMID- 29569284 TI - Low frequency of acetyl salicylic acid hypersensitivity in mastocytosis: The results of a double-blind, placebo-controlled challenge study. AB - BACKGROUND: Patients with mastocytosis are at increased risk of anaphylaxis. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) is often discouraged because of this reason. However, the actual prevalence and severity of NSAID-related hypersensitivity among patients with mastocytosis is unknown. METHODS: A double blind, placebo-controlled acetylsalicylic acid (ASA) challenge up to a cumulative dose of 520 mg was performed among adult patients with mastocytosis. In addition, a retrospective search of the entire outpatient cohort was performed to obtain "real-life" data on NSAID hypersensitivity. RESULTS: Fifty patients underwent an ASA challenge. Seventy percent had indolent systemic mastocytosis, 18% had mastocytosis in the skin, and 12% had advanced mastocytosis. The ASA challenge was positive in 1 patient who developed urticaria. The additional retrospective chart review revealed that 8 of 191 patients had a history of NSAID-related hypersensitivity reaction(s), of whom 3 reported severe systemic reactions. All 8 patients had already experienced NSAID-related hypersensitivity reactions before mastocytosis was diagnosed. CONCLUSIONS: The frequency of ASA hypersensitivity was 2% in a prospective challenge study and 4.1% in a retrospective chart review of 191 patients with mastocytosis. NSAIDs can be administered safely to most patients with mastocytosis. Extra caution should be taken in patients with a history of hypersensitivity reactions to other drugs, or traditional risk factors for NSAID hypersensitivity. PMID- 29569285 TI - The dimerization of PSGL-1 is driven by the transmembrane domain via a leucine zipper motif. AB - P-selectin glycoprotein ligand-1 (PSGL-1) is a homodimeric mucin ligand that is important to mediate the earliest adhesive event during an inflammatory response by rapidly forming and dissociating the selectin-ligand adhesive bonds. Recent research indicates that the noncovalent associations between the PSGL-1 transmembrane domains (TMDs) can substitute for the C320-dependent covalent bond to mediate the dimerization of PSGL-1. In this article, we combined TOXCAT assays and molecular dynamics (MD) simulations to probe the mechanism of PSGL-1 dimerization. The results of TOXCAT assays and Martini coarse-grained molecular dynamics (CG MD) simulations demonstrated that PSGL-1 TMDs strongly dimerized in a natural membrane and a leucine zipper motif was responsible for the noncovalent dimerization of PSGL-1 TMD since mutations of the residues that occupied a or d positions in an (abcdefg)n leucine heptad repeat motif significantly reduced the dimer activity. Furthermore, we studied the effects of the disulfide bond on the PSGL-1 dimer using MD simulations. The disulfide bond was critical to form the leucine zipper structure, by which the disulfide bond further improved the stability of the PSGL-1 dimer. These findings provide insights to understand the transmembrane association of PSGL-1 that is an important structural basis for PSGL-1 preferentially binding to P-selectin to achieve its biochemical and biophysical functions. PMID- 29569286 TI - Real-life experiences of people with transient ischaemic attack or minor stroke: A qualitative literature review. AB - AIMS AND OBJECTIVES: To explore and present findings of qualitative studies exploring real-life experiences of people with transient ischaemic attack or minor stroke. BACKGROUND: Transient ischaemic attack and minor stroke significantly increase the risk of stroke. Primarily, literature has examined healthcare pathways, patient outcomes and models of care through quantitative methodologies. Several studies have explored patient experiences using qualitative approaches. However, these findings have not been systematically collated or critically appraised to better understand the experiences of this population. DESIGN: A literature review of the qualitative evidence. METHOD: A systematic literature search was conducted in CINAHL, MEDLINE, EMBASE and PsycINFO between January 2005-October 2016 to identify qualitative studies that explored real-life experiences of people with transient ischaemic attack or minor stroke. The relevant EQUATOR guidelines were followed. Findings of relevant studies were critically appraised and collated using a thematic approach. RESULTS: The search retrieved 709 articles. Twelve articles were included after critical review. Three themes emerged including recognition, awareness and action; the vulnerable self; and social and personal life change. Participants experienced ongoing vulnerability and change in their personal and social lives. Specifically, people believed that their condition did not reflect their physical appearance and led to their needs being unmet by health professionals. CONCLUSIONS: This is the first review of the literature to collate the thoughts, perspectives and experiences of people living with transient ischaemic attack or minor stroke. They reveal a complex, life-altering experience characterised by vulnerability, instability and change. Education that assists clinicians to connect with these experiences may alleviate the patient-reported disconnection with health professionals. RELEVANCE TO CLINICAL PRACTICE: Physical and psychosocial dysfunctions were consistently reported to be overlooked or undetected by clinicians. Educating clinicians might enable them to better understand patient experiences, improve therapeutic interactions and meet the needs of this population.

AB - The notion that halide perovskite crystals (ABX3 , where X is a halide) exhibit unique structural and optoelectronic behavior deserves serious scrutiny. After decades of steady and half a decade of intense research, the question which attributes of these materials are unusual, is discussed, with an emphasis on the identification of the most important remaining issues. The goal is to stimulate discussion rather than to merely present a community consensus.

PMID- 29569290 TI - The genetic variance but not the genetic covariance of life-history traits changes towards the north in a time-constrained insect. AB - Seasonal time constraints are usually stronger at higher than lower latitudes and can exert strong selection on life-history traits and the correlations among these traits. To predict the response of life-history traits to environmental change along a latitudinal gradient, information must be obtained about genetic variance in traits and also genetic correlation between traits, that is the genetic variance-covariance matrix, G. Here, we estimated G for key life-history traits in an obligate univoltine damselfly that faces seasonal time constraints. We exposed populations to simulated native temperatures and photoperiods and common garden environmental conditions in a laboratory set-up. Despite differences in genetic variance in these traits between populations (lower variance at northern latitudes), there was no evidence for latitude-specific covariance of the life-history traits. At simulated native conditions, all populations showed strong genetic and phenotypic correlations between traits that shaped growth and development. The variance-covariance matrix changed considerably when populations were exposed to common garden conditions compared with the simulated natural conditions, showing the importance of environmentally induced changes in multivariate genetic structure. Our results highlight the importance of estimating variance-covariance matrixes in environments that mimic selection pressures and not only trait variances or mean trait values in common garden conditions for understanding the trait evolution across populations and environments.

AB - BACKGROUND: Staphylococcus pseudintermedius and Malassezia pachydermatis are important agents in canine pyoderma and otitis. HYPOTHESIS/OBJECTIVES: Determine the in vitro efficacy of a honey-based gel (HBO) against meticillin-susceptible S. pseudintermedius (MSSP), meticillin-resistant S. pseudintermedius (MRSP) and M. pachydermatis, by minimum bactericidal concentration (MBC), minimum fungicidal concentration (MFC) and time-kill assay (TKA). Efficacy of the product's honey component (HO) also was evaluated. METHODS: Sixty S. pseudintermedius and 10 M. pachydermatis canine isolates were selected. All isolates were tested against serial dilutions of an HBO containing 40% HO (40%, 20%, 10%, 5% and 2.5% w/v) and HO alone (undiluted, 40%, 20%, 10%, 5% and 2.5% w/v). Microbroth assay followed by subculture was used to determine MBC and MFC. The same protocol was applied after product exposure to catalase. A well-diffusion assay for S. pseudintermedius was used to generate inhibition zones. A TKA for 10 isolates of S. pseudintermedius and 10 isolates of M. pachydermatis was performed. RESULTS: MBC was 20% w/v (5-20% w/v) for HBO and HO. HBO had lower MBC values when compared to HO (P = 0.003). No statistical difference was observed between MSSP/MRSP isolates (HBO P = 0.757, HO P = 0.743). Only HO was affected by catalase (P = 0.015). MFC for HBO was 10% w/v (5-10% w/v) and 40% w/v for HO (20 >=40% w/v). All isolates were killed after 4 h of exposure. CONCLUSIONS AND CLINICAL IMPORTANCE: Staphylococcus pseudintermedius and M. pachydermatis are susceptible to the HBO and these results can be used for future clinical trials. PMID- 29569292 TI - Effect of spatial connectivity on host resistance in a highly fragmented natural pathosystem. AB - Both theory and experimental evolution studies predict migration to influence the outcome of antagonistic coevolution between hosts and their parasites, with higher migration rates leading to increased diversity and evolutionary potential. Migration rates are expected to vary in spatially structured natural pathosystems, yet how spatial structure generates variation in coevolutionary trajectories across populations occupying the same landscape has not been tested. Here, we studied the effect of spatial connectivity on host evolutionary potential in a natural pathosystem characterized by a stable Plantago lanceolata host network and a highly dynamic Podosphaera plantaginis parasite metapopulation. We designed a large inoculation experiment to test resistance of five isolated and five well-connected host populations against sympatric and allopatric pathogen strains, over 4 years. Contrary to our expectations, we did not find consistently higher resistance against sympatric pathogen strains in the well-connected populations. Instead, host local adaptation varied considerably among populations and through time with greater fluctuations observed in the well connected populations. Jointly, our results suggest that in populations where pathogens have successfully established, they have the upper hand in the coevolutionary arms race, but hosts may be better able to respond to pathogen imposed selection in the well-connected than in the isolated populations. Hence, the ongoing and extensive fragmentation of natural habitats may increase vulnerability to diseases. PMID- 29569293 TI - Peripheral giant cell granuloma: An updated analysis of 2824 cases reported in the literature. AB - OBJECTIVE: To integrate the available data published on peripheral giant cell granuloma (PGCG) into a comprehensive analysis of its clinical/radiological features. MATERIALS AND METHODS: An electronic search was undertaken in January 2018 in 5 databases, looking for publications reporting cases of PGCGs. Probability of recurrence was calculated for some variables. RESULTS: A total of 165 publications were included, 2824 lesions identified. PGCGs were slightly more prevalent in women and more prevalent in mandibles, usually asymptomatic, and presenting erosion of the subjacent bone in almost one-third of cases. Additional curettage (2.8%) or peripheral osteotomy (0%) after excision presented lower recurrence rates in comparison with excision alone (16%). Excision followed by curettage decreases the probability of recurrence by 85% in comparison with excision alone. Other factors (age, lesion size, follow-up, gender, location, clinical symptoms, bone erosion) seem to do not influence the probability of recurrence. CONCLUSIONS: As surgical excision alone shows a considerable recurrence rate, excision followed by an additional therapy-curettage or peripheral osteotomy-should be the first choice of treatment of PGCG. PMID- 29569294 TI - Acute myeloid leukemia (AML) with t(7;12)(q36;p13) is associated with infancy and trisomy 19: Data from Nordic Society for Pediatric Hematology and Oncology (NOPHO AML) and review of the literature. AB - The t(7;12)(q36;p13) (MNX1/ETV6) is not included in the WHO classification but has been described in up to 30% of acute myeloid leukemia (AML) in children <2 years and associated with a poor prognosis. We present the clinical and cytogenetics characteristics of AML cases with t(7;12)(p36;p13). A literature review identified 35 patients with this translocation, published between 2000 and 2015. Outcome data were available in 22 cases. The NOPHO-AML (Nordic Society for Pediatric Hematology and Oncology) database contained 651 patients with AML from 1993 to 2014 and seven (1.1%) had the translocation. The t(7;12) was only present in patients <2 years of age (median age 6 months) but none was diagnosed as newborn. These patients constituted 4.3% of the patients <2 years of age. There was a strong association with trisomy 19 (literature: 86%, NOPHO: 100%) and +8 (literature: 19%, NOPHO: 14%). Seventeen of 22 patients from the literature with t(7;12) and four of seven patients from the NOPHO database suffered from relapse. The patients with t(7;12) had a 3-year event free survival of 24% (literature) vs. 43% (NOPHO) and a 3-year overall survival of 42% (literature) vs. 100% (NOPHO). None of the NOPHO patients was treated with hematopoietic stem cell transplantation (HSCT) in first complete remission. Relapse was frequent but the salvage rate using HSCT was high. We conclude that t(7;12)(q36;13) is a unique subgroup of childhood AML with presentation before 2 years of age with most cases being associated with +19. PMID- 29569296 TI - Exacerbation of atopic dermatitis symptoms by ustekinumab in psoriatic patients with elevated serum immunoglobulin E levels: Report of two cases. AB - Psoriasis is a chronic inflammatory skin disease mainly mediated by a T-helper cell subset, Th17 cells. Recently, increased levels of total serum immunoglobulin (Ig)E have been reported in a subset of psoriatic patients. Ustekinumab (UST) is one of the most commonly used biologic agents for the treatment of moderate to severe plaque psoriasis, and a previous report also documented effectiveness of UST for psoriatic patients with high serum IgE levels. We experienced two psoriatic patients with high serum IgE levels, in whom UST completely improved psoriasis but paradoxically provoked or exacerbated atopic dermatitis (AD)-like symptoms. This reciprocal phenomenon suggests the shift of Th balance toward Th2, along with altered profiles of inflammatory cytokines. It appears prudent to consider the possibility of such adverse effects when treating psoriatic patients with UST with concomitant AD symptoms, a history of AD or high serum IgE levels. PMID- 29569297 TI - Maternal virus infections in pregnancy and type 1 diabetes in their offspring: Systematic review and meta-analysis of observational studies. AB - Virus infections are implicated in the development of type 1 diabetes based on epidemiological, clinical, in vitro cell-based and molecular studies, and animal models. We reviewed the association between virus infections in pregnant women and development of islet autoimmunity or type 1 diabetes in their offspring. We performed a systematic review and meta-analysis, analysed using random effects models, of human studies from Medline and EMBASE without language restriction. Inclusion criteria were as follows: cohort and case-control studies measuring viral nucleic acid in blood, stool, urine, or tissue, or serological tests for viruses, in pregnant women whose offspring developed islet autoimmunity and/or type 1 diabetes. All studies required sufficient data to calculate odds ratios and 95% confidence intervals. The 10 studies (4 case control, 6 nested-case control) that met the eligibility criteria included 2992 participants (953 offspring, 2039 mothers), with varying study design. The 2 outcomes examined were islet autoimmunity (n = 466) and type 1 diabetes (n = 2526). Meta-analysis showed a significant association between virus infection during pregnancy and clinical type 1 diabetes during childhood (odds ratio 2.16, 95% CI 1.22-3.80; P = 0.008; heterogeneity X2 = 1.65, I2 = 40%), but no association with islet autoimmunity (1.45, 0.63-3.31; P = 0.38; X2 = 1.34, I2 = 25%). The increased risk of type 1 diabetes following maternal virus infection is consistent with viraemia involving the fetus during pregnancy and suggests a potential causative link between antenatal infection and type 1 diabetes. Larger prospective birth studies with more frequent sampling, and pathogenesis studies, are required to more clearly establish an aetiological link. PMID- 29569298 TI - Reconfigurable Diodes Based on Vertical WSe2 Transistors with van der Waals Bonded Contacts. AB - New device concepts can increase the functionality of scaled electronic devices, with reconfigurable diodes allowing the design of more compact logic gates being one of the examples. In recent years, there has been significant interest in creating reconfigurable diodes based on ultrathin transition metal dichalcogenide crystals due to their unique combination of gate-tunable charge carriers, high mobility, and sizeable band gap. Thanks to their large surface areas, these devices are constructed under planar geometry and the device characteristics are controlled by electrostatic gating through rather complex two independent local gates or ionic-liquid gating. In this work, similar reconfigurable diode action is demonstrated in a WSe2 transistor by only utilizing van der Waals bonded graphene and Co/h-BN contacts. Toward this, first the charge injection efficiencies into WSe2 by graphene and Co/h-BN contacts are characterized. While Co/h-BN contact results in nearly Schottky-barrier-free charge injection, graphene/WSe2 interface has an average barrier height of ~80 meV. By taking the advantage of the electrostatic transparency of graphene and the different work function values of graphene and Co/h-BN, vertical devices are constructed where different gate-tunable diode actions are demonstrated. This architecture reveals the opportunities for exploring new device concepts. PMID- 29569295 TI - Daily allergic multimorbidity in rhinitis using mobile technology: A novel concept of the MASK study. AB - BACKGROUND: Multimorbidity in allergic airway diseases is well known, but no data exist about the daily dynamics of symptoms and their impact on work. To better understand this, we aimed to assess the presence and control of daily allergic multimorbidity (asthma, conjunctivitis, rhinitis) and its impact on work productivity using a mobile technology, the Allergy Diary. METHODS: We undertook a 1-year prospective observational study in which 4 210 users and 32 585 days were monitored in 19 countries. Five visual analogue scales (VAS) assessed the daily burden of the disease (i.e., global evaluation, nose, eyes, asthma and work). Visual analogue scale levels <20/100 were categorized as "Low" burden and VAS levels >=50/100 as "High" burden. RESULTS: Visual analogue scales global measured levels assessing the global control of the allergic disease were significantly associated with allergic multimorbidity. Eight hypothesis-driven patterns were defined based on "Low" and "High" VAS levels. There were <0.2% days of Rhinitis Low and Asthma High or Conjunctivitis High patterns. There were 5.9% days with a Rhinitis High-Asthma Low pattern. There were 1.7% days with a Rhinitis High-Asthma High-Conjunctivitis Low pattern. A novel Rhinitis High Asthma High-Conjunctivitis High pattern was identified in 2.9% days and had the greatest impact on uncontrolled VAS global measured and impaired work productivity. Work productivity was significantly correlated with VAS global measured levels. CONCLUSIONS: In a novel approach examining daily symptoms with mobile technology, we found considerable intra-individual variability of allergic multimorbidity including a previously unrecognized extreme pattern of uncontrolled multimorbidity. PMID- 29569299 TI - Digit identity influences numerical estimation in children and adults. AB - Learning the meanings of Arabic numerals involves mapping the number symbols to mental representations of their corresponding, approximate numerical quantities. It is often assumed that performance on numerical tasks, such as number line estimation (NLE), is primarily driven by translating from a presented numeral to a mental representation of its overall magnitude. Part of this assumption is that the overall numerical magnitude of the presented numeral, not the specific digits that comprise it, is what matters for task performance. Here we ask whether the magnitudes of the presented target numerals drive symbolic number line performance, or whether specific digits influence estimates. If the former is true, estimates of numerals with very similar magnitudes but different hundreds digits (such as 399 and 402) should be placed in similar locations. However, if the latter is true, these placements will differ significantly. In two studies (N = 262), children aged 7-11 and adults completed 0-1000 NLE tasks with target values drawn from a set of paired numerals that fell on either side of "Hundreds" boundaries (e.g., 698 and 701) and "Fifties" boundaries (e.g., 749 and 752). Study 1 used an atypical speeded NLE task, while Study 2 used a standard non speeded NLE task. Under both speeded and non-speeded conditions, specific hundreds digits in the target numerals exerted a strong influence on estimates, with large effect sizes at all ages, showing that the magnitudes of target numerals are not the primary influence shaping children's or adults' placements. We discuss patterns of developmental change and individual difference revealed by planned and exploratory analyses. PMID- 29569300 TI - Roles of three FurA paralogs in the regulation of genes pertaining to peroxide defense in Mycobacterium smegmatis mc2 155. AB - Mycobacterium smegmatis mc2 155 has three genes (MSMEG_6383, furA1; MSMEG_3460, furA2; MSMEG_6253, furA3) encoding FurA (ferric-uptake regulator A) paralogs. Three FurA paralogs in M. smegmatis are functionally redundant and negatively regulate expression of a subset of genes involved in peroxide detoxification such as ahpC, katG1 and katG2, as well as their own genes. The FurA paralogs sense H2 O2 via metal-catalyzed His oxidation (MCHO) in the same way as PerR. The propensity of FurA2 and FurA3 for MCHO is greater than that of FurA1. The three furA genes are transcribed into leaderless mRNAs lacking the Shine-Dalgarno (SD) sequence. FurA1 and FurA3 have the quaternary structure of homodimers like most Fur homologs, whereas FurA2 occurs as a monomer. The monomeric structure of FurA2 is determined by the C-terminal region of its dimerization domain. FurA2 monomers appear to cooperatively bind to the FurA-binding site with an inverted repeat configuration and have a broader binding specificity for the target DNA than dimeric FurA1 and FurA3. Comparative transcriptomic analysis revealed that the FurA paralogs do not regulate genes related to iron homeostasis in M. smegmatis, and that expression of SigF-regulated genes is significantly decreased in a furA triple mutant relative to the wild-type strain of M. smegmatis. PMID- 29569301 TI - Nongrowing season methane emissions-a significant component of annual emissions across northern ecosystems. AB - Wetlands are the single largest natural source of atmospheric methane (CH4 ), a greenhouse gas, and occur extensively in the northern hemisphere. Large discrepancies remain between "bottom-up" and "top-down" estimates of northern CH4 emissions. To explore whether these discrepancies are due to poor representation of nongrowing season CH4 emissions, we synthesized nongrowing season and annual CH4 flux measurements from temperate, boreal, and tundra wetlands and uplands. Median nongrowing season wetland emissions ranged from 0.9 g/m2 in bogs to 5.2 g/m2 in marshes and were dependent on moisture, vegetation, and permafrost. Annual wetland emissions ranged from 0.9 g m-2 year-1 in tundra bogs to 78 g m-2 year-1 in temperate marshes. Uplands varied from CH4 sinks to CH4 sources with a median annual flux of 0.0 +/- 0.2 g m-2 year-1 . The measured fraction of annual CH4 emissions during the nongrowing season (observed: 13% to 47%) was significantly larger than that was predicted by two process-based model ensembles, especially between 40 degrees and 60 degrees N (modeled: 4% to 17%). Constraining the model ensembles with the measured nongrowing fraction increased total nongrowing season and annual CH4 emissions. Using this constraint, the modeled nongrowing season wetland CH4 flux from >40 degrees north was 6.1 +/- 1.5 Tg/year, three times greater than the nongrowing season emissions of the unconstrained model ensemble. The annual wetland CH4 flux was 37 +/- 7 Tg/year from the data-constrained model ensemble, 25% larger than the unconstrained ensemble. Considering nongrowing season processes is critical for accurately estimating CH4 emissions from high-latitude ecosystems, and necessary for constraining the role of wetland emissions in a warming climate. PMID- 29569302 TI - Extraintestinal manifestations were common in children with coeliac disease and were more prevalent in patients with more severe clinical and histological presentation. AB - AIM: This study investigated the prevalence of extraintestinal manifestations (EIM) in paediatric coeliac disease and their associations with other disease features. METHODS: Researchers at the University of Tampere, Finland, compared EIM in 511 children diagnosed with coeliac disease from 2003 to 2014 and 180 diagnosed with functional gastrointestinal disorders from 2007 to 2013. Disease severity and dietary responses were also compared between coeliac children diagnosed by screening (n = 146) or because of EIM (n = 116) or gastrointestinal symptoms (n = 249). RESULTS: Coeliac patients had more EIM (62%) than those with functional disorders (33%). The most common EIM in coeliac children were poor growth (27%) and anaemia (18%). Children with coeliac disease often showed fatigue (8%) and symptoms affecting the skin (15%), nervous system (9%) and joints (6%). Coeliac patients with EIM as their main clinical presentation had more severe symptoms and histological damage at diagnosis than those with gastrointestinal presentation and screen-detected cases. The subgroups did not differ with regard to other clinical and laboratory parameters and dietary adherence. Concomitant EIM were also common in children diagnosed because of gastrointestinal presentation (60%) and by screening (37%). CONCLUSION: EIM were common in coeliac disease and associated with more severe clinical and histological presentation. PMID- 29569303 TI - Photodynamic inactivation of Listeria innocua biofilms with food-grade photosensitizers: a curcumin-rich extract of Curcuma longa vs commercial curcumin. AB - AIMS: The aim of this work is to assess the potential of curcumin in the photosensitization of biofilms of Listeria. METHODS AND RESULTS: Biofilms of Listeria innocua, were irradiated with blue light in the presence of a curcumin rich extract of Curcuma longa or commercial curcumin. Similar experiments were conducted with planktonic cells, for comparison. A reduction of 4.9 log in the concentration of viable biofilm cells was obtained with 3.7 mg l-1 of commercial curcumin. Planktonic cells were much more susceptible (6.1 log reduction). A tetracationic porphyrin, used as a reference photosensitizer (PS), caused a very modest inactivation of the biofilm (1.1 log) and complete inactivation of the planktonic form (>8 log). CONCLUSIONS: Curcumin is an effective PS for the photodynamic control of Listeria biofilms and the inactivation efficiency attained with this natural compound is higher than with the porphyrin. This result may point to a better performance of type I PSs against bacterial biofilms by circumventing the limitations to singlet-oxygen diffusion imposed by the extracellular matrix. SIGNIFICANCE AND IMPACT OF THE STUDY: Curcumin represents a promising alternative to the control of bacteria and bacterial biofilms in food products particularly in the case of meat products in which turmeric is used as spice. PMID- 29569304 TI - Phenotypic and functional alterations of myeloid-derived suppressor cells during the disease course of multiple sclerosis. AB - Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system involving dysregulated encephalitogenic T cells. Myeloid-derived suppressor cells (MDSCs) have been recognized for their important function in regulating T-cell responses. Recent studies have indicated a role for MDSCs in autoimmune diseases, but their significance in MS is not clear. Here, we assessed the frequencies of CD14+ HLA-DRlow monocytic MDSCs (Mo-MDSCs) and CD33+ CD15+ CD11b+ HLA-DRlow granulocytic MDSCs (Gr-MDSCs) and investigated phenotypic and functional differences of Mo-MDSCs at different clinical stages of MS and in healthy subjects (HC). Increased frequencies of Mo-MDSCs (P < 0.05) and Gr-MDSCs (P < 0.05) were observed in relapsing-remitting MS patients during relapse (RRMS relapse) compared to stable RRMS (RRMS-rem). Secondary progressive MS (SPMS) patients displayed a decreased frequency of Mo-MDSCs and Gr-MDSCs compared to HC (P < 0.05). Mo-MDSCs within RRMS patients expressed significantly higher cell surface protein levels of CD86 and CD163 compared to SPMS patients. Mo-MDSCs within SPMS exhibited decreased mRNA expression of interleukin-10 and heme oxygenase 1 compared to RRMS and HC. Analysis of T-cell regulatory function of Mo MDSCs demonstrated T-cell suppressive capacity in RRMS and HCs, while Mo-MDSCs of SPMS promoted autologous T-cell proliferation, which aligned with a differential cytokine profile compared to RRMS and HCs. This study is the first to show phenotypic and functional shifts of MDSCs between clinical stages of MS, suggesting a role for MDSCs as a therapeutic target to prevent MS disease progression. PMID- 29569305 TI - Enzymatic activities and pathogenesis-related genes expression in sunflower inbred lines affected by Sclerotinia sclerotiorum culture filtrate. AB - AIMS: Studying biochemical responses and pathogenesis-related gene expression in sunflower-Sclerotinia interaction can shed light on factors participating to disease resistance. METHODS AND RESULTS: Partially resistant and susceptible lines were exposed to pathogen culture filtrate. The activity of antioxidant enzymes and proline was much more pronounced in partially resistant line. The more resistant to Sclerotinia sclerotiorum, the less (1,4)-beta-glucanase activity was observed. PDF 1.2 and PR5-1 exhibited higher transcript abundance in the partially resistant line than in the susceptible line. CONCLUSIONS: Considering the dual roles of oxalic acid, activation of the antioxidant system in partially resistant line might lead to suppression of oxidative burst which is beneficial for the growth of fungus at later stages of infection. The ability of the partially resistant line in balancing antioxidant enzymes could reserve H2 O2 as a substrate for peroxidase that might lead to lignification. The contribution of (1,4)-beta-glucanase defence responses against Sclerotinia was observed. The roles of SA and JA marker genes were demonstrated in sunflower defence responses. SIGNIFICANCE AND IMPACT OF THE STUDY: The time of antioxidant system activation in host is important in order to contribute to defence responses. To date, the changes in the expression of PR1 and PDF 1.2 and contribution of (1,4)-beta glucanase enzyme in sunflower defence responses were not reported in previous studies.

PMID- 29569309 TI - Patterns of reproductive isolation in a haplodiploid - strong post-mating, prezygotic barriers among three forms of a social spider mite. AB - In speciation research, much attention is paid to the evolution of reproductive barriers, preventing diverging groups from hybridizing back into one gene pool. The prevalent view is that reproductive barriers evolve gradually as a by-product of genetic changes accumulated by natural selection and genetic drift in groups that are segregated spatially and/or temporally. Reproductive barriers, however, can also be reinforced by natural selection against maladaptive hybridization. These mutually compatible theories are both empirically supported by studies, analysing relationships between intensity of reproductive isolation and genetic distance in sympatric taxa and allopatric taxa. Here, we present the - to our knowledge - first comparative study in a haplodiploid organism, the social spider mite Stigmaeopsis miscanthi, by measuring premating and post-mating, pre- and post-zygotic components of reproductive isolation, using three recently diverged forms of the mite that partly overlap in home range. We carried out cross experiments and measured genetic distances (mitochondrial DNA and nuclear DNA) among parapatric and allopatric populations of the three forms. Our results show that the three forms are reproductively isolated, despite the absence of premating barriers, and that the post-mating, prezygotic component contributes most to reproductive isolation. As expected, the strength of post-mating reproductive barriers positively correlated with genetic distance. We did not find a clear pattern of prezygotic barriers evolving faster in parapatry than in allopatry, although one form did show a trend in line with the ecological and behavioural relationships between the forms. Our study advocates the versatility of haplodiploid animals for investigating the evolution of reproductive barriers. PMID- 29569310 TI - Molecular model for neuroendocrine prostate cancer progression. AB - Prostate cancer (PCa) is the most common form of cancer in men in the developed world and the second leading cause of cancer-related deaths. While advanced PCa is initially controlled with hormonal therapies targeting the androgen receptor (AR) pathway, recurrence occurs because of the emergence of lethal castration resistant PCa (CRPC). Despite newer AR pathway inhibitors that prolong survival, resistance still emerges, most often with rising PSA levels indicative of AR driven activity, but increasingly as non-AR-driven cancer. Treatment resistance mechanisms include AR-signalling pathway alterations, AR-signalling bypass mechanisms, and AR-independent clonal evolution. The latter mechanism can lead to the emergence of neuroendocrine prostate cancer (NEPC), an aggressive lethal subtype of PCa. The incidence of treatment-induced NEPC is rising because of the widespread use of more potent AR pathway inhibitors. This comprehensive review of major NEPC drivers and facilitators defines three coordinated processes contributing to NEPC progression. Specifically, castration-resistant adenocarcinoma cells gain lineage plasticity under selective pressures of potent AR suppression to transform into AR-independent tumour cells. In concert, neuroendocrine (NE)-specific transdifferentiation factors induce NE lineage of these PCa cells, which, with support of increased proliferation factors, contributes to clonal expansion and tumour repopulation into NEPC. We examine the roles of each of the major NEPC contributors during the disease progression and identify potential therapeutic opportunities for targeted therapies. PMID- 29569311 TI - Initial series of magnetic resonance imaging (MRI)-fusion targeted prostate biopsy using the first transperineal targeted platform available in the USA. AB - OBJECTIVES: To describe a step-by-step guide for using the first transperineal targeted prostate biopsy platform available in the USA. PATIENTS AND METHODS: A total of 32 men with elevated prostate-specific antigen (PSA) levels were diagnosed with a region of interest on multiparametric magnetic resonance imaging (mpMRI) between February 2017 and January 2018. The transperineal targeted prostate biopsy procedure was accomplished via a transperineal approach and used a stepper, combined with advanced mpMRI/transrectal ultrasound fusion software, to perform targeted prostate biopsy. The detection of overall and clinically significant prostate cancer (PCa) was assessed as well as the rate of complications. RESULTS: The median patient age was 68.0 years and the median PSA was 8.0 ng/mL. Two patients (6%) were active surveillance candidates and 16 (50%) had a prior negative prostate biopsy. The detection rates for overall and clinically significant PCa were 81% and 59%, respectively. The two candidates for active surveillance and eight of the patients with a prior negative prostate biopsy had clinically significant PCa confirmed on targeted biopsy. There were no peri-operative complications. CONCLUSION: These results demonstrate the promising potential of the first transperineal targeted prostate biopsy platform in the USA as an alternative diagnostic method for PCa. PMID- 29569312 TI - Substance-use initiation moderates the effect of stress on white-matter microstructure in adolescents. AB - BACKGROUND: While childhood stress may contribute risk to substance-use initiation and differences in brain white-matter development, understanding of the potential impact of substance-use initiation on the relationship between experienced stress and white-matter microstructure remains limited. OBJECTIVES: This study examined whether substance-use initiation moderated the effect of perceived stress on white-matter differences using measures of primary white matter fiber anisotropy. METHODS: Forty adolescents (age 14.75 +/- .87 years) were assessed on the Perceived Stress Scale, and 50% were determined to have presence of substance-use initiation. White-matter microstructure was examined using primary-fiber orientations anisotropy, which may reflect white-matter integrity, modeled separately from other fiber orientations in the same voxels. Analyses were conducted on regions of interest previously associated with childhood stress and substance use. RESULTS: Lower perceived stress and presence of substance-use initiation were related to greater right cingulum primary-fiber measures. Substance-use-initiation status moderated the association between perceived stress and right cingulum primary-fiber measures, such that higher perceived stress was associated with lower right cingulum primary-fiber anisotropy in adolescents without substance-use initiation, but not in those with substance-use initiation. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Findings in primary-fiber anisotropy suggest differences in right cingulum white-matter integrity is associated with substance-use initiation in higher-stress adolescents. This reflects a possible pre-existing risk factor, an impact of early substance use, or a combination thereof.

AB - AIMS: The duodenal-jejunal bypass liner (DJBL) is an endoscopic device mimicking surgical duodenal-jejunal bypass, and is indicated for the treatment of obesity associated type 2 diabetes mellitus. This analysis was conducted to evaluate the efficacy and safety of the DJBL in comparison to lifestyle changes and antidiabetic drugs. MATERIALS AND METHODS: To determine the efficacy and long term safety of the DJBL, data concerning 235 obese patients with type 2 diabetes mellitus from the German DJBL registry were analysed. For comparison with standard treatment, propensity-score-matching with patients from the German DPV registry, including the matching parameters sex, age, diabetes duration, baseline BMI and baseline HbA1c, was applied. The final matched cohort consisted of 111 patients in the DJBL group and 222 matched control DPV patients. RESULTS: Mean treatment time with the DJBL was 47.5 +/- 12.2 weeks, mean BMI reduction was 5.0 kg/m2 (P < .001) and mean HbA1c reduction was 1.3% (11.9 mmol/mol) (P < .001). Reduction of antidiabetic medications and improvements in other metabolic and cardiovascular risk parameters was observed. In comparison to the matched control group, mean reductions in HbA1c (-1.37% vs -0.51% [12.6 vs 3.2 mmol/mol]; P < .0001) and BMI (-3.02 kg/m2 vs -0.39 kg/m2 ; P < .0001) were significantly higher. Total cholesterol, LDL cholesterol and blood pressure were also significantly better. CONCLUSION: This study provides the largest, so far, hypothesis-generating evidence for a putative positive risk/benefit ratio for treatment of obese patients with type 2 diabetes mellitus with the DJBL as an alternative treatment option for this patient population.

AB - Molecular knots have become highly attractive to chemists because of their prospective properties in mimicking biomolecules and machines. Only a few examples of molecular knots from the billions tabulated by mathematicians have been realized and molecular knots with more than eight crossings have not been reported to date. We report here the coordination-driven [8+8] self-assembly of a higher-generation molecular knot comprising as many as sixteen crossings. Its solid-state X-ray crystal structure and multinuclear 2D NMR findings confirmed its architecture and topology. The formation of this molecular knot appears to depend on the functionalities and geometries of donor and acceptor in terms of generating appropriate angles and strong pi-pi interactions supported by hydrophobic effects. This study shows coordination-driven self-assembly offers a powerful potential means of synthesizing more and more complicated molecular knots and of understanding differences between the properties of knotted and unknotted structures.

AB - Interest in bay-substituted perylene-3,4:9,10-tetracarboxylic diimides (PDIs) for solution-based applications is growing due to their improved solubility and altered optical and electronic properties compared to unsubstituted PDIs. Synthetic routes to 1,12-bay-substituted PDIs have been very demanding due to issues with steric hindrance and poor regioselectivity. Here we report a simple one-step regioselective and high yielding synthesis of a 1,12-dihydroxylated PDI derivative that can subsequently be alkylated in a straightforward fashion to produce nonplanar 1,12-dialkoxy PDIs. These PDIs show a large Stokes shift, which is specifically useful for bioimaging applications. A particular cationic PDI gemini-type surfactant has been developed that forms nonfluorescent self assembled particles in water ("off state"), which exerts a high fluorescence upon incorporation into lipophilic bilayers ("on state"). Therefore, this probe is appealing as a highly sensitive fluorescent labelling marker with a low background signal for imaging artificial and cellular membranes. PMID- 29569316 TI - Improved prediction of fungal effector proteins from secretomes with EffectorP 2.0. AB - Plant-pathogenic fungi secrete effector proteins to facilitate infection. We describe extensive improvements to EffectorP, the first machine learning classifier for fungal effector prediction. EffectorP 2.0 is now trained on a larger set of effectors and utilizes a different approach based on an ensemble of classifiers trained on different subsets of negative data, offering different views on classification. EffectorP 2.0 achieves an accuracy of 89%, compared with 82% for EffectorP 1.0 and 59.8% for a small size classifier. Important features for effector prediction appear to be protein size, protein net charge as well as the amino acids serine and cysteine. EffectorP 2.0 decreases the number of predicted effectors in secretomes of fungal plant symbionts and saprophytes by 40% when compared with EffectorP 1.0. However, EffectorP 1.0 retains value, and combining EffectorP 1.0 and 2.0 results in a stringent classifier with a low false positive rate of 9%. EffectorP 2.0 predicts significant enrichments of effectors in 12 of 13 sets of infection-induced proteins from diverse fungal pathogens, whereas a small cysteine-rich classifier detects enrichment in only seven of 13. EffectorP 2.0 will fast track the prioritization of high-confidence effector candidates for functional validation and aid in improving our understanding of effector biology. EffectorP 2.0 is available at http://effectorp.csiro.au. PMID- 29569317 TI - The urgency to embrace Big Data opportunities in medicine. PMID- 29569319 TI - Modeling the Impact of Stream Discharge Events on Riparian Solute Dynamics. AB - The biogeochemical composition of stream water and the surrounding riparian water is mainly defined by the exchange of water and solutes between the stream and the riparian zone. Short-term fluctuations in near stream hydraulic head gradients (e.g., during stream flow events) can significantly influence the extent and rate of exchange processes. In this study, we simulate exchanges between streams and their riparian zone driven by stream stage fluctuations during single stream discharge events of varying peak height and duration. Simulated results show that strong stream flow events can trigger solute mobilization in riparian soils and subsequent export to the stream. The timing and amount of solute export is linked to the shape of the discharge event. Higher peaks and increased durations significantly enhance solute export, however, peak height is found to be the dominant control for overall mass export. Mobilized solutes are transported to the stream in two stages (1) by return flow of stream water that was stored in the riparian zone during the event and (2) by vertical movement to the groundwater under gravity drainage from the unsaturated parts of the riparian zone, which lasts for significantly longer time (> 400 days) resulting in long tailing of bank outflows and solute mass outfluxes. We conclude that strong stream discharge events can mobilize and transport solutes from near stream riparian soils into the stream. The impact of short-term stream discharge variations on solute exchange may last for long times after the flow event. PMID- 29569318 TI - Insulin resistance is associated with smaller brain volumes in a preliminary study of depressed and obese children. AB - OBJECTIVE: During childhood, the brain can consume up to 65% of total calories, and a steady supply of the brain's main fuel glucose needs to be maintained. Although the brain itself is not dependent on insulin for the uptake of glucose, insulin plays an important role in energy homeostasis. Thus, the risk for insulin resistance during brain development may negatively impact the whole brain volume. METHODS: We investigated the link between the insulin resistance and the whole brain volume as measured by structural Magnetic resonance imaging (MRI) in 46 unmedicated depressed and overweight youths between the ages of 9 and 17 years. RESULTS: Smaller whole brain volumes were associated with insulin resistance independent of age, sex, depression severity, body mass index, socioeconomic status, Tanner Stage, and Intelligence quotient (IQ) (r = 0.395, P = .014) CONCLUSIONS: There may be a significant cost for developing insulin resistance on the developing brain. Disentangling the precise relationship between the insulin resistance and the developing brain is critical. PMID- 29569321 TI - Blood pressure profile and nocturnal oxygen desaturation. PMID- 29569320 TI - Primary magnetic resonance imaging/ultrasonography fusion-guided biopsy of the prostate. AB - OBJECTIVE: To examine the performance of a primary magnetic resonance imaging (MRI)/ultrasonography (US) fusion-guided targeted biopsy (TB), and in combination with an added systematic biopsy (SB). PATIENTS AND METHODS: Analysis of 318 consecutive biopsy-naive men with suspicious multiparametric MRI (mpMRI; Prostate Imaging Reporting and Data System [PI-RADS] score >=3) undergoing transrectal TB and 10-core SB between January 2012 and December 2016. The indication for performing mpMRI was based on clinical parameters and decided by the treating urologist before admission. TB was performed with a sensor-based MRI/US fusion guided platform. Clinically significant prostate cancer was defined as Gleason score >=4 + 3 = 7 (International Society of Urological Pathology Grade [ISUP] grade 3) or maximum cancer core length of >=6 mm. RESULTS: A median (interquartile range) of 14 (13-14) biopsies per case were taken. The overall cancer detection rate (CDR) was 77% (245/318). The TB alone detected 67% of prostate cancers and the SB alone detected 70%. The PI-RADS dependent CDR for the combination of TB/SB were 38% (21/55), 78% (120/154) and 95% (104/109) for PI RADS scores of 3/4/5, respectively. Clinically significant prostate cancer was diagnosed by the combination of TB and SB in 195 men (61%) and by TB alone in 163 cases (51%). The number of missed or underestimated prostate cancers with a Gleason score >=8 for TB alone was 31 (10%, P < 0.001) and 21 (7%, P < 0.001) for SB alone in comparison with the results of the combination of TB and SB. The rate of insignificant prostate cancer was comparable for the combination of TB and SB and TB alone (50/318, 16% vs 50/318, 16%). CONCLUSIONS: Pre-biopsy mpMRI is of incremental value in increasing the detection of clinically significant prostate cancer in biopsy-naive patients with suspicion of prostate cancer. Combining TB with SB further improved the diagnostic accuracy without increasing the rate of insignificant prostate cancer.

PMID- 29569323 TI - Real-world observational results from a database of 48 million men in the United States: Relationship of cardiovascular disease, diabetes mellitus and depression with age and erectile dysfunction. AB - AIMS: To evaluate the relationship of comorbidities (cardiovascular disease [CVD], diabetes mellitus [DM] and depression) with erectile dysfunction (ED) and age using real-world claims data from 48 million men in the United States. METHODS: This was a cross-sectional, non-interventional study in men aged >=18 years using data from the Truven Health MarketScan(r) and Medicare Supplemental Research Databases from January 2010 to December 2015, with an observational period of January 2011 to December 2014 to allow for 12 months pre- and post index. Comorbidity rate was compared between ED and non-ED groups by age using the chi2 (bivariate) test. Comorbidity relationship to ED after controlling for categorical variables was assessed using logistic regression analysis. RESULTS: In all, 48 004 379 men were in the database. Of the 9 839 578 who met the inclusion criteria, 573 313 (6%) were ED patients and 9 266 265 (94%) were non-ED patients. ED diagnosis increased decade to decade from 18-29 years to 50-59 years but decreased from 60-69 years to >=90 years. ED patients had a higher prevalence of CVD, DM and depression than non-ED patients in all periods (P < .0001). After controlling for potential demographic and baseline confounders, the association between ED and CVD, DM and depression remained significant for each age group beginning at 30-39 years (P < .0001). DISCUSSION: Conversations with patients concerning ED should be comprehensive regardless of patient age, in particular in those who have CVD, DM and/or depression. CONCLUSIONS: In the real-world setting, ED diagnosis was associated with CVD, DM and depression across age groups, suggesting a need for inquiry about the potential for comorbidities among these men as a preventative measure against potentially serious future events. PMID- 29569324 TI - Distinct gene expression pathways in islets from individuals with short- and long duration type 1 diabetes. AB - AIMS: Our current understanding of the pathogenesis of type 1 diabetes (T1D) arose, in large part, from studies using the non-obese diabetic (NOD) mouse model. In the present study, we chose a human-focused method to investigate T1D disease mechanisms and potential targets for therapeutic intervention by directly analysing human donor pancreatic islets from individuals with T1D. MATERIALS AND METHODS: We obtained islets from a young individual with T1D for 3 years and from an older individual with T1D for 27 years and performed unbiased functional genomic analysis by high-depth RNA sequencing; the T1D islets were compared with islets isolated from 3 non-diabetic donors. RESULTS: The islets procured from these T1D donors represent a unique opportunity to identify gene expression changes in islets after significantly different disease duration. Data analysis identified several inflammatory pathways up-regulated in short-duration disease, which notably included many components of innate immunity. As proof of concept for translation, one of the pathways, governed by IL-23(p19), was selected for further study in NOD mice because of ongoing human trials of biologics against this target for different indications. A mouse monoclonal antibody directed against IL-23(p19) when administered to NOD mice resulted in a significant reduction in incidence of diabetes. CONCLUSION: While the sample size for this study is small, our data demonstrate that the direct analysis of human islets provides a greater understanding of human disease. These data, together with the analysis of an expanded cohort to be obtained by future collaborative efforts, might result in the identification of promising novel targets for translation into effective therapeutic interventions for human T1D, with the added benefit of repurposing known biologicals for use in different indications. PMID- 29569325 TI - Biocompatibility and hemocompatibility of efficiently decellularized whole porcine kidney for tissue engineering. AB - Whole kidney decellularization is a promising approach in regenerative medicine for engineering a functional organ. The reaction of the potential host depends on the biocompatibility of these decellularized constructs. Despite the proven ability of decellularized kidney scaffolds to guide cell attachment and growth, little is known about biocompatibility and hemocompatibility of these scaffolds. Our aim is to prepare decellularized kidneys of a clinically relevant size and evaluate its biocompatibility and hemocompatibility. Porcine kidneys were cannulated via the renal artery, and then perfused with 0.1% sodium dodecyl sulfate solution. Hematoxylin and eosin as well as DAPI staining confirmed cellular clearance from native kidneys in addition to preservation of the microstructure. SEM confirmed the absence of any cellular content within the scaffold, which is maintained in a well-organized 3D architecture. Decellularized kidneys retained the intact renal vasculature upon examination with contrast radiography. The essential structural extracellular matrix molecules were well preserved. Scaffolds were susceptible to enzymatic degradation upon collagenase treatment. Scaffolds showed a good hemocompatibility when exposed to porcine blood. Decellularization was efficient to remove 97.7% of DNA from native kidneys in addition to the immunogenic and pathogenic antigens. Scaffolds did not induce the human immune response in vitro. Decellularized kidneys were non-cytotoxic to pig kidney cells (PKs). PKs were able to grow and proliferate within the decellularized renal scaffolds with maintaining a higher function than cells grown as monolayers. Thus, we have developed a rapid decellularization technique for generating biocompatible kidney scaffolds that represents a step toward development of a transplantable organ.

PMID- 29569326 TI - In vitro and in vivo performance of methacrylated gellan gum hydrogel formulations for cartilage repair. AB - Methacrylated gellan gum (GGMA) formulation is proposed as a second-generation hydrogel for controlled delivery of cartilage-forming cells into focal chondral lesions, allowing immediate in situ retention of cells and 3D filling of lesion volume, such approach deemed compatible with an arthroscopic procedure. Formulation optimization was carried out in vitro using chondrocytes and adipose mesenchymal stromal/stem cells (ASCs). A proof-of-concept in vivo study was conducted using a rabbit model with induced chondral lesions. Outcomes were compared with microfracture or non-treated control. Three grading scores were used to evaluate tissue repair after 8 weeks by macroscopic, histological and immunohistochemical analysis. Intense collagen type II and low collagen type I gene and protein expression were achieved in vitro by the ASC + GGMA formulation, in light with development of healthy chondral tissue. In vivo, this formulation promoted significantly superior de novo cartilage formation compared with the non treated group. Maintenance of chondral height and integration with native tissue was further accomplished. The physicochemical properties of the proposed GGMA hydrogel exhibited highly favorable characteristics and biological performance both in vitro and in vivo, positioning itself as an attractive xeno-free biomaterial to be used with chondrogenic cells for a cost-effective treatment of focal chondral lesions.

PMID- 29569327 TI - Reducing Emergency Room Visits and In-Hospitalizations by Implementing Best Practice for Transitional Care Using Innovative Technology and Big Data. AB - BACKGROUND: Efforts to improve care transitions require coordination across the healthcare continuum and interventions that enhance communication between acute and community settings. AIMS: To improve post-discharge utilization value using technology to identify high-risk individuals who might benefit from rapid nurse outreach to assess social and behavioral determinants of health with the goal of reducing inpatient and emergency department visits. METHODS: The project employed a before and after comparison of the intervention site with similar primary care practice sites using population-level Medicaid claims data. The intervention targeted discharged persons with preexisting chronic disease and delivered a care transition alert to a nurse care coordinator for immediate telephonic outreach. The nurse assessed social determinants of health and incorporated problems into the EHR to share across settings. The project evaluated health outcomes and the value of nursing care on existing electronic claims data to compare utilization in the years before and during the intervention using negative binomial regression to account for rare events such as inpatient visits. RESULTS: Avoiding readmissions and emergency visits, and increasing timely outpatient visits improved the individual's experience of care and the work life of healthcare providers, while reducing per capita costs (Quadruple Aim). In the intervention practice, the nurse care coordinator demonstrated the value of nursing care by reducing inpatient (25%) and emergency (35%) visits, and increasing outpatient visits (27%). The estimated value of avoided encounters over the secular Medicaid trend was $664 per adult with chronic disease, generating $71,289 in revenue from additional outpatient visits. LINKING EVIDENCE TO ACTION: Using health information exchange to deliver appropriate and timely evidence-based clinical decision support in the form of care transition alerts and assessment of social determinants of health, in conjunction with data science methods, demonstrates the value of nursing care and resulted in achieving the Quadruple Aim. PMID- 29569328 TI - A randomized clinical trial to evaluate the efficacy of contingency management for treatment of waterpipe tobacco addiction. AB - BACKGROUND AND OBJECTIVES: Unlike cigarette smoking cessation, waterpipe tobacco smoking cessation is relatively understudied. The objective of this randomized clinical trial was to examine the efficacy of contingency management (CM) for promoting initial waterpipe smoking abstinence. METHODS: The study used a two group, repeated measures design. Participants attended 10 visits (two visits per week, on Mondays and Thursdays) across 5 weeks. Thirty-nine adult waterpipe tobacco users who did not smoke cigarettes and were not planning on quitting waterpipe tobacco smoking were randomly assigned to either the contingent (n = 19) or non-contingent (n = 20) groups. Contingent group received monetary rewards based on negative salivary cotinine results. Earning rewards started at $14 and increased by $.50 with each subsequent negative sample for a maximum $192.50. Non contingent group earned rewards independent of salivary cotinine results. Prolonged abstinence was defined as having negative salivary cotinine results for eight or more visits (two lapses were allowed); and 7-day point prevalence was defined as having negative salivary cotinine results at visit 9 and 10 (final week). RESULTS: The prolonged abstinence rate in the contingent and non contingent groups were 42.1% and 5.0%, respectively, (p = .008). The 7-day point prevalence in the contingent and non-contingent were 47.4% and 5.0%, respectively, (p = .003). DISCUSSION AND CONCLUSIONS: Rewards contingent on biochemically verified abstinence promote initial waterpipe tobacco cessation. This is useful information for consideration in future cessation programs for waterpipe smokers. SCIENTIFIC SIGNIFICANCE: CM strategy may have potential benefit in addressing waterpipe tobacco smoking in non-treatment seeking adults. (Am J Addict 2018;27:202-209).

AB - We present the detailed characterization on the reconstitution of two cyclic tetrapyrrole pigments that have the same substituents but differ in the degree of hydrogenation in the macrocycles from bacteriochlorophyll (BChl) a (7,8,17,18 tetrahydroporphyrin) into the binding sites of B800 BChl a in light-harvesting complex 2 (LH2) of purple photosynthetic bacteria. Both 3-acetyl chlorophyll (Chl) a (17,18-dihydroporphyrin) and 3-acetyl protochlorophyll (PChl) a (porphyrin) were inserted into the B800-binding pockets in LH2, indicating that these pockets allow alteration of the degree of hydrogenation in the cyclic tetrapyrroles. Redshifts of the Qy peak positions of 3-acetyl (P)Chl a by insertion into the B800-binding sites were smaller than that of BChl a. The relative Qy absorbance of 3-acetyl (P)Chl a to B850 BChl a in the reconstituted proteins was significantly smaller than that of B800 BChl a in native LH2 in spite of their high occupancy in the B800-binding sites. These are ascribable to the smaller dipole strengths of 3-acetyl (P)Chl a. We also performed the coreconstitution of both 3-acetyl Chl a and BChl a into the nine B800-binding sites in LH2, indicating that the affinity of 3-acetyl Chl a to the B800-cavity was slightly higher than that of BChl a. PMID- 29569331 TI - Mesenchymal stem cell seeded, biomimetic 3D printed scaffolds induce complete bridging of femoral critical sized defects. AB - No current clinical treatments provide an ideal long-term solution for repair of long bone segment defects. Incomplete healing prevents patients from returning to preinjury activity and ultimately requires additional surgery to induce healing. Obtaining autologous graft material is costly, incurs morbidity, requires surgical time, and quality material is finite. In this pilot study, 3D printed biomimetic scaffolds were used to facilitate rapid bone bridging in critical sized defects in a sheep model. An inverse trabecular pattern based on micro-CT scans of sheep trabecular bone was printed in polybutylene terephthalate. Scaffolds were coated with micron-sized tricalcium phosphate particles to induce osteoconductivity. Mesenchymal stem cells (MSCs) were isolated from sheep inguinal and tail fat, in one group of sheep and scaffolds were infiltrated with MSCs in a bioreactor. Controls did not undergo surgery for cell extraction. Scaffolds were implanted into two experimental and two control adult sheep, and followed for either 3 or 6 months. Monthly radiographs and post explant micro-CT scanning demonstrated bone formation on the lateral, anterior, medial, and posterior-medial aspects along the entire length of the defect. Bone formation was absent on the posterior-lateral aspect where a muscle is generally attached to the bone. The 3-month time point showed 15.5% more cortical bone deposition around the scaffold circumference while the 6-month time point showed 40.9% more bone deposition within scaffold pores. Control sheep failed to unite. Serum collagen type-1C-terminus telopeptides (CTX-1) showed time-dependent levels of bone resorption, and calcein labeling demonstrated an increase in bone formation rate in treated animals compared with controls.

PMID- 29569332 TI - The impact of coronary chronic total occlusion percutaneous coronary intervention upon donor vessel fractional flow reserve and instantaneous wave-free ratio: Implications for physiology-guided PCI in patients with CTO. AB - OBJECTIVE: To investigate the immediate and short term impact of right coronary artery (RCA) chronic total coronary occlusion (CTO) percutaneous coronary intervention (PCI) upon collateral donor vessel fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR). BACKGROUND: CTO PCI influences collateral donor vessel physiology, making the indication and/or timing of donor vessel revascularization difficult to determine. METHODS: In patients with RCA CTO, FFR, iFR, and collateral function index (FFRcoll ) were measured in LAD and LCx pre CTO PCI, immediately post and at 4 month follow-up. RESULTS: 34 patients underwent successful PCI. In the predominant donor vessel immediately post PCI, FFR, and FFRcoll did not change (0.76 +/- 0.12 to 0.75 +/- 0.13, P = 0.267 and 0.31 +/- 0.10 vs. 0.34 +/- 0.11, P = 0.078), but iFR increased significantly (0.86 +/- 0.10 to 0.88 +/- 0.10, P = 0.012). At follow-up, there was a significant increase in predominant donor FFR and iFR (0.76 +/- 0.12 to 0.79 +/- 0.11, P = 0.047 and 0.86 +/- 0.10 to 0.90 +/- 0.07, P = 0.003), accompanied by a significant reduction in FFRcoll (0.31 +/- 0.10 to 0.18 +/- 0.07 P < 0.0001). These changes resulted in a reclassification of the predominant donor vessel from ischemic to nonischemic in 18% (FFR) and 25% (iFR) of the cases, respectively. CONCLUSIONS: Successful recanalization of an RCA CTO resulted in a modest but statistically significant increase in the predominant donor vessel immediately post CTO PCI in the case of iFR and at 4-month follow-up for FFR and iFR compared to pre-PCI with a concomitant reduction in collateral function. PMID- 29569333 TI - Vacuumed collagen-impregnated bioglass scaffolds: Characterization and influence on proliferation and differentiation of bone marrow stromal cells. AB - This study evaluated physical-chemical characteristics of a vacuumed collagen impregnated bioglass (BG) scaffolds and bone marrow stromal cells (BMSCs) behavior on those composites. scanning electron microscope and energy dispersive x-ray spectroscope demonstrated collagen (Col) was successfully introduced into BG. Vacuum impregnation system has showed efficiency for Col impregnation in BG scaffolds (approximately 20 wt %). Furthermore, mass weight decreasing and more stabilized pH were observed over time for BG/Col upon incubation in phosphate buffered saline compared to plain BG under same conditions. Calcium evaluation (Ca assay) demonstrated higher calcium uptake for BG/Col samples compared to BG. In addition, BG samples presented hydroxyapatite crystals formation on its surface after 14 days in simulated body fluid solution, and signs of initial degradation were observed for BG and BG/Col after 21 days. Fourier transform infrared spectroscopy spectra for both groups indicated peaks for hydroxyapatite formation. Finally, a significant increase of BMSCs viability for both composites was observed compared to control group, but no increase of osteogenic differentiation-related gene expressions were found. In summary, BG/Col scaffolds have improved degradation, pH equilibrium and Ca mineralization over time, accompanied by hydroxyapatite formation. Moreover, both BG and BG/Col scaffolds were biocompatible and noncytotoxic, promoting a higher cell viability compared to control. Future investigations should focus on additional molecular and in vivo studies in order to evaluate biomaterial performance for bone tissue engineering applications. (c) 2018 Wiley Periodicals, Inc.

AB - PURPOSE: To examine the relationships of self-care, symptoms, and a variety of demographic factors to quality of life (QOL), and to identify determinants of QOL in lung cancer patients undergoing chemotherapy. DESIGN: A cross-sectional, correlational study. METHODS: 159 patients with lung cancer undergoing chemotherapy were recruited from three southern hospitals in Taiwan. Four instruments were used: the Quality of Life Questionnaire Core 30-item (QLQ-C30), M.D. Anderson Symptom Inventory (MDASI), Memorial Symptom Assessment Scale-Short Form (MSAS-SF), and Self-Care Behavior Scale (SCBS). FINDINGS: Lung cancer patients rated lower scores of self-care behaviors on food choice and nutrition maintenance, regular exercise and sleep, and medical compliance. Being younger, having spouses as main caregivers, having food choice and nutrition maintenance, and getting regular exercise and sleep were associated with better QOL. Degree of interference with life, age, food choice and nutrition maintenance, and psychological symptoms were found to predict functional QOL and accounted for 43% of total variance. CONCLUSIONS: The findings identified factors influencing QOL and provided evidence for designing an intervention to enhance QOL in lung cancer patients undergoing chemotherapy. CLINICAL RELEVANCE: The findings may be useful for guiding intervention development for early detection and management of symptom interference with daily living, and place greater focus on patient self care to promote food choice and nutrition maintenance, especially in older patients and those whose caregivers are not their spouses. PMID- 29569335 TI - The taphonomic fate of isorenieratene in Lower Jurassic shales-controlled by iron? AB - Fossil derivatives of isorenieratene, an accessory pigment in brown-colored green sulfur bacteria, are often used as tracers for photic zone anoxia through Earth's history, but their diagenetic behavior is still incompletely understood. Here, we assess the preservation of isorenieratene derivatives in organic-rich shales (1.5 8.4 wt.% TOC) from two Lower Jurassic anoxic systems (Bachental oil shale, Tyrol, Austria; Posidonia Shale, Baden-Wurttemberg, Germany). Bitumens and kerogens were investigated using catalytic hydropyrolysis (HyPy), closed-system hydrous pyrolysis (in gold capsules), gas chromatography-mass spectrometry (GC-MS) and gas chromatography combustion isotope ratio-mass spectrometry (GC-C-IRMS). Petrography and biomarkers indicate a syngenetic relationship between bitumens and kerogens. All bitumens contain abundant isorenieratane, diverse complex aromatized isorenieratene derivatives, and a pseudohomologous series of 2,3,6 trimethyl aryl isoprenoids. In contrast, HyPy and mild closed-system hydrous pyrolysis of the kerogens yielded only minor amounts of these compounds. Given the overall low maturity of the organic matter (below oil window), it appears that isorenieratene and its abundant derivatives from the bitumen had not been incorporated into the kerogens. Accordingly, sulfur cross-linking, the key mechanism for sequestration of functionalized lipids into kerogens in anoxic systems, was not effective in the Jurassic environments studied. We explain this by (i) early cyclization/aromatization and (ii) hydrogenation reactions that have prevented effective sulfurization. In addition, (iii) sulfide was locally removed via anoxygenic photosynthesis and efficiently trapped by the reaction with sedimentary iron, as further indicated by elevated iron contents (4.0-8.7 wt.%) and the presence of abundant pyrite aggregates in the rock matrix. Although the combined processes have hampered the kerogen incorporation of isorenieratene and its derivatives, they may have promoted the long-term preservation of these biomarkers in the bitumen fraction via early defunctionalization. This particular taphonomy of aromatic carotenoids has to be considered in studies of anoxic iron rich environments (e.g., the Proterozoic ocean). PMID- 29569336 TI - Nonmedical prescription stimulant users experience subjective but not objective impairments in attention and impulsivity. AB - BACKGROUND AND OBJECTIVES: Nonmedical prescription stimulant use is frequently reported by college students to improve academic performance, yet it is unknown whether users truly experience cognitive impairments that may drive use. This research compared students with at least one report of nonmedical prescription stimulant use and nonusers on both self-report and objective measures of inattention and impulsivity. METHODS: Two studies examined inattention (N = 155) and impulsivity (N = 115) among college students. Participants completed self report questionnaires and cognitive tests, including Digit Span, the Paced Auditory Serial Addition Test, and a Continuous Performance Test to assess inattention, and the Balloon Analogue Risk Task and the Stop Signal Task to assess risk-taking and impulsivity. RESULTS: Self-reports of inattention and impulsive symptoms were significantly higher among users, controlling for gender, GPA, self-reported ADHD, alcohol use, and drug use; however, no objective differences were found. DISCUSSION AND CONCLUSIONS: Nonmedical prescription stimulant users may engage in use to overcome perceived deficits in cognitive abilities despite lack of objective evidence. SCIENTIFIC SIGNIFICANCE: Understanding discrepancies in objective performance and subjective reports may aid in the development of effective interventions for nonmedical prescription stimulant use.

AB - BACKGROUND: Chronic rhinosinusitis is a common disease process in humans; however, in the primate population of gorillas, it has rarely been described. This case describes lifesaving sinus surgery on a critically ill gorilla performed by a human otolaryngology team in collaboration with the gorilla's veterinary medicine team. METHODS: The 35-year-old western silverback gorilla was treated for 3 months with aggressive medical therapy for a worsening sinus infection. When his condition became severe, a computed tomography (CT) scan was performed showing advanced chronic rhinosinusitis with nasal polyps vs other masses and some bone erosion. As his condition deteriorated further, a tertiary otolaryngology team performed sinus surgery using the latest technology available, including image guidance, steroid-eluting sinus stents, and balloon sinus dilation. The postoperative course was complicated by subcutaneous infection and eventual fistulization. Fortunately, with culture-directed antibiotic therapy his condition gradually improved. One year later he required revision sinus surgery. At that point allergy testing was performed followed by appropriate allergy medical therapy. Now, 3 years out from his initial surgery, he continues to do well and has fathered a young female gorilla. RESULTS: This case represents a unique collaboration between human physicians and veterinarians. The combined medical approach was critical to heal this ailing gorilla. This case discusses many of the challenges and offers recommendations for physicians who may be involved with similar care of animals in the future. CONCLUSION: The success of the surgical and medical treatment of this gorilla's life-threatening sinus infection required many experts, careful planning, and corporate generosity. The interaction between human and animal medicine would not have been successful without the close and trusting collaborations between human and veterinary health providers. We encourage human healthcare providers to seek volunteer opportunities through their local zoos by engaging in discussions with their local veterinarians. PMID- 29569339 TI - A D-vine copula-based model for repeated measurements extending linear mixed models with homogeneous correlation structure. AB - We propose a model for unbalanced longitudinal data, where the univariate margins can be selected arbitrarily and the dependence structure is described with the help of a D-vine copula. We show that our approach is an extremely flexible extension of the widely used linear mixed model if the correlation is homogeneous over the considered individuals. As an alternative to joint maximum-likelihood a sequential estimation approach for the D-vine copula is provided and validated in a simulation study. The model can handle missing values without being forced to discard data. Since conditional distributions are known analytically, we easily make predictions for future events. For model selection, we adjust the Bayesian information criterion to our situation. In an application to heart surgery data our model performs clearly better than competing linear mixed models. PMID- 29569337 TI - Diabetes, Cardiovascular Disorders and 2,3,7,8-Tetrachlorodibenzo-p-Dioxin Body Burden in Czech Patients 50 Years After the Intoxication. AB - The correlation between 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) intoxication and the parameters of metabolic impairment was examined in the last eight male survivors of 80 workers exposed to TCDD during the production of herbicides in a chemical factory in 1965-1967. Their median TCDD blood level was 112 (46-390) pg/g lipids, and the median TCDD body deposit was 3.9 (0.8-11.7) MUg. This puts these patients into the most severely intoxicated group of subjects, according to back-calculated levels of TCDD. The median TCDD blood level in eight controls was 12 pg/g (<0.10 to 22.2 pg/g). Markers of metabolic impairment - diabetes, dyslipidaemia, arterial hypertension, carotid artery plaque, skin microvascular reactivity, eye fundus hypertensive angiopathy and history of coronary heart disease - were assessed and compared to a general male population of comparable age. Measured parameters compared with a population of comparable age were as follows: prevalence of diabetes (62.5% versus 17.6%), arterial hypertension (87.5% versus 71.8%), dyslipidaemia (87.5% versus 88.8%), history of coronary heart disease (62.5% versus 26.0%) and eye fundus hypertension angiopathy (50% versus 14%). All eight patients (100% versus 43%) developed plaques in carotid arteries, six had stenosis >50% and two had a carotid intervention (stenting or endarterectomy). Total cholesterol levels decreased compared to the earlier study this patient group in 2008, most likely due to a more intensive use of lipid lowering drugs. Several metabolic parameters were higher (diabetes as much as 3.5 fold) in the group of severely TCDD-intoxicated subjects than in a general population of comparable age. This suggests that TCDD plays a role in the development of metabolic impairment and vascular changes. PMID- 29569340 TI - Seventy Years of RN Effectiveness: A Database Development Project to Inform Best Practice. AB - BACKGROUND: The appropriate nursing staff mix is imperative to the provision of quality care. Nurse staffing levels and staff mix vary from country to country, as well as between care settings. Understanding how staffing skill mix impacts patient, organizational, and financial outcomes is critical in order to allow policymakers and clinicians to make evidence-informed staffing decisions. AIMS: This paper reports on the methodology for creation of an electronic database of studies exploring the effectiveness of Registered Nurses (RNs) on clinical and patient outcomes, organizational and nurse outcomes, and financial outcomes. METHODS: Comprehensive literature searches were conducted in four electronic databases. Inclusion criteria for the database included studies published from 1946 to 2016, peer-reviewed international literature, and studies focused on RNs in all health-care disciplines, settings, and sectors. Masters-prepared nurse researchers conducted title and abstract screening and relevance review to determine eligibility of studies for the database. High-level analysis was conducted to determine key outcomes and the frequency at which they appeared within the database. RESULTS: Of the initial 90,352 records, a total of 626 abstracts were included within the database. Studies were organized into three groups corresponding to clinical and patient outcomes, organizational and nurse related outcomes, and financial outcomes. Organizational and nurse-related outcomes represented the largest category in the database with 282 studies, followed by clinical and patient outcomes with 244 studies, and lastly financial outcomes, which included 124 studies. LINKING EVIDENCE TO ACTION: The comprehensive database of evidence for RN effectiveness is freely available at https://rnao.ca/bpg/initiatives/RNEffectiveness. The database will serve as a resource for the Registered Nurses' Association of Ontario, as well as a tool for researchers, clinicians, and policymakers for making evidence-informed staffing decisions. PMID- 29569341 TI - Bariatric surgery in solid organ transplant patients: Long-term follow-up results of outcome, safety, and effect on immunosuppression. AB - The surgical risk of transplanted patients is high, and the modified gastrointestinal anatomy after bariatric surgery (BS) may lead to pharmacokinetic alterations in the absorption of immunosuppressive drugs. Data on outcomes of BS and the safety and feasibility of maintaining immunosuppression and graft safety among solid organ transplanted patients are scarce. In the current study, weight loss, improvement in comorbidities, and changes in dosage and trough levels of immunosuppression drugs before and after BS were analyzed for all transplanted patients who underwent laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux en-Y gastric bypass (LRYGB) in our institution between November 2011 and January 2017. Thirty-four patients (13 females, 21 males, average age 53 years) were included in the study. A successful weight loss (>50% excess weight loss in 28 of them [82%]) was recorded at the last follow-up. Comorbidities improved significantly. Immunosuppressive stability increased from 39% to 47% among all patients. The tacrolimus blood trough levels declined slightly, but remained within therapeutic range. These data suggest that LSG and LRYGB ensure good immunosuppressive maintenance together with significant weight loss and improvement in comorbidities without serious graft rejection or dysfunction. The surgical risk is higher than in the regular BS population.

AB - : Conversion of the cellular prion protein PrPC into its pathogenic isoform PrPSc is the hallmark of prion diseases, fatal neurodegenerative diseases affecting many mammalian species including humans. Anti-prion monoclonal antibodies can arrest the progression of prion diseases by stabilizing the cellular form of the prion protein. Here, we present the crystal structure of the POM6 Fab fragment, in complex with the mouse prion protein (moPrP). The prion epitope of POM6 is in close proximity to the epitope recognized by the purportedly toxic antibody fragment, POM1 Fab also complexed with moPrP. The POM6 Fab recognizes a larger binding interface indicating a likely stronger binding compared to POM1. POM6 and POM1 exhibit distinct biological responses. Structural comparisons of the bound mouse prion proteins from the POM6 Fab:moPrP and POM1 Fab:moPrP complexes reveal several key regions of the prion protein that might be involved in initiating mis folding events. DATABASE: The structural data of moPrP:POM6 Fab complex are available in the PDB under the accession number www.rcsb.org/pdb/search/structidSearch.do?structureId=6AQ7.

AB - Bone morphogenetic protein-2 (BMP-2) is commonly used to enhance bone regeneration. The potential of BMP-2 for bone regeneration varies according to the concentration and release kinetics on the implanted site. Therefore, it is important to determine appropriate carriers of BMP-2. However, no optimal delivery vehicles have been identified. In the present study, we used alginate microbeads as a delivery vehicle for BMP-2. Alginate microbeads can be implanted onto the disease site through surgery or injection. The objective of this study was to evaluate that the osteoinductive properties of BMP-2 are effective in alginate microbeads as a carrier. In this study, the release kinetics of BMP-2 in alginate microbeads was evaluated using an enzyme-linked immunosorbent assay. BMP 2 released from alginate microbeads induced high alkaline phosphatase activity in canine adipose tissue-derived mesenchymal stem cells. Injection of alginate microbeads with BMP-2 into mouse subcutaneous tissue, as well as surgical implantation into the 5-mm circular calvarial defects in rats, was conducted and the results showed extensive new bone formation. In conclusion, alginate microbeads can be utilized as an effective BMP-2 delivery vehicle for use in orthopedic surgery and as an injectable vehicle for a minimally invasive therapy.

AB - Alcohol addiction is a chronic neuropsychiatric disorder that represents one of the most serious global public health problems. Yet, currently there still lacks an effective pharmacotherapy. Omega-3 polyunsaturated fatty acids (N-3 PUFAs) have exhibited beneficial effects in a variety of neurological disorders, particularly in reversing behavioral deficits and neurotoxicity induced by prenatal alcohol exposure and binge drinking. In the present study, we investigated if fish oil, which is rich in N-3 PUFAs, had beneficial effects on preventing relapse and alleviating withdrawal symptoms after chronic alcohol exposure. Our results demonstrated that fish oil significantly reduced the chronic alcohol exposure-induced aberrant dendritic morphologic changes of the medium-sized spiny neurons in the core and the shell of nucleus accumbens. This inhibited the expression of AMPAR2-lacking AMPARs and their accumulation on the post synaptic membranes of medium-sized spiny neurons and eventually alleviated withdrawal symptoms and alcohol dependence. Our study therefore suggests that N-3 PUFAs are promising for treating withdrawal symptoms and alcohol dependence. PMID- 29569347 TI - First year medical student peer nominations of professionalism: A methodological detective story about making sense of non-sense. AB - This article explores the assessment of professionalism within a cohort of medical students during a sequential 13-week medical school histology and anatomy course. Across seven data points, students were asked to identify a professionalism role model from amongst their peers and to score Likert structured rationales for their decision. Based on density scores, an initial social network analysis identified six peer-nomination "stars." However, analysis of these stars revealed considerable variability and random-like "noise" in both the nomination and explanation data sets. Subsequent analyses of both data sets explored the possibility of underlying patterns in this noise using tests of reliability, principal components factor analysis, and fixed-effects regression analysis. These explorations revealed the presence of two dimensions (professional vs. supportive) in how students sought to explain their nomination decisions. Although data variability remained quite high, significantly less variability was present in the professional than in the supportive dimension, suggesting that academic helpfulness rationales are both empirically distinct and more mutable than rationales grounded in professionalism-related factors. In addition, data showed that the greater the stability in one's choice of a professionalism role model nomination over the T1-T7 data periods, the more stable one's reasons for that nomination-both for professionalism and supportive dimensions. Results indicate that while peer assessment of professionalism by first-year medical students may not be very reliable, students can differentiate between more personal and professional factors, even at this early stage in their professional development. Formal instruction within the pre-clinical curriculum should recognize and address this distinction. Anat Sci Educ. (c) 2018 American Association of Anatomists. PMID- 29569346 TI - Evolution of caudal fin ray development and caudal fin hypural diastema complex in spotted gar, teleosts, and other neopterygian fishes. AB - BACKGROUND: The caudal fin of actinopterygians transitioned from a heterocercal dorsoventrally asymmetrical fin to a homocercal externally symmetrical fin in teleosts through poorly understood evolutionary developmental mechanisms. We studied the caudal skeleton of major living actinopterygian lineages, including polypteriformes, acipenseriformes, Holostei (gars and bowfin), and teleosts, compared with reports of extinct neopterygians and basal teleosteans. We focused on the hypural diastema complex, which includes (1) a gap between hypurals 2 and 3, that (2) separates two plates of connective tissue at (3) the branching of caudal vasculature; these features had been considered as a shared, derived trait of teleosts, a synapomorphy. RESULTS: These studies revealed that gars and teleosts share all three features of the hypural diastema complex. Absence of a complex with these features from bowfin, fossil Holostei, and stem Teleostei argues in favor of repetitive, independent emergence in several neopterygian and basal Teleostei lineages, or less likely, many independent losses. We further observed that, in gars and teleosts, the earliest developing lepidotrichia align with the horizontal adult body axis, thus participating in external symmetry. CONCLUSIONS: These results suggest that the hypural diastema complex in teleosts and gars represents a homoplasy among neopterygians and that it emerged repeatedly by parallel evolution due to shared inherited underlying genetic and developmental programs (latent homology). Because the hypural diastema complex exists in gars with heterocercal tails, this complex is independent of homocercality. Developmental Dynamics 247:832-853, 2018. (c) 2018 Wiley Periodicals, Inc.

AB - This study showed the results of a monitoring program aimed at detecting the fraudulent use of horse meat in samples collected in the framework of official controls during the years 2013-2017 after the so-called horse meat scandal that caused a decreasing consumer confidence in the food industry, particularly in meat products. A total of 125 samples diversely distributed in the 5 years of monitoring were analyzed by liquid chromatography-tandem mass spectrometry (LC MS/MS). The method was validated according to Commission Decision 657/2002/EC with regard to the following parameters: linearity, specificity, decision limit (CCalpha), detection capability (CCbeta), recovery, and precision (repeatability and within-laboratory reproducibility). Even if the results of this study revealed no positive sample, the need for constant assurance of food safety and consumers' health protection requires the implementation of preventive as well as corrective actions in the management of risks linked to the food chain in a more global context.

PMID- 29569350 TI - Waist-to-height ratio remains an accurate and practical way of identifying cardiometabolic risks in children and adolescents. AB - AIM: We evaluated how effectively the waist-to-height ratio (WHtR) identified cardiometabolic risk (CMR) in children and adolescents, compared with the tri ponderal mass index, percentage of body fat and other obesity indexes. METHODS: Eligible subjects were recruited from three metropolitan regions of China from May 2013 to June 2014. Subjects with at least three of the following abnormalities - hypertension, dyslipidemia, elevated fasting blood glucose and central obesity - were defined as CMR1 and children with at least two were defined as CMR2. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare how effectively obesity indexes predicted CMR. RESULTS: We recruited 3556 subjects aged 7-18 years. All five obesity indexes showed good, comparable performances in identifying CMR and the AUCs ranged from 0.89 to 0.90 for CMR1 and 0.83 to 0.85 for CMR2. The cut-off of 0.467 for WHtR achieved a sensitivity of 0.91 and specificity of 0.80 for predicting CMR1, with the best cut-offs being 0.463 for boys and 0.469 for girls. CONCLUSION: The WHtR was a superior and practical screening tool for detecting CMR in this paediatric population, as it provided comparable accuracy to other methods and just required a simple calculation. PMID- 29569351 TI - Preliminary Clinical Evaluation of Acupuncture Therapy in Patients With Postpartum Sciatica. AB - INTRODUCTION: This study evaluated clinical outcomes following acupuncture treatment of postpartum sciatica. METHODS: One hundred eleven women with postpartum sciatica were enrolled in an acupuncture group (n = 86) or a control group (n = 25), according to their preference. Participants in the acupuncture group attended acupuncture therapy sessions 3 times a week for 4 weeks, while participants in the control group were assigned to bed rest. Outcome measures included the Roland Disability Questionnaire for sciatica, a visual analog scale for leg pain, and patient-reported perceived recovery. In addition, participants were surveyed after treatment to assess the acceptability of acupuncture therapy. RESULTS: The outcome scores for disability and leg pain were significantly lower in the acupuncture group compared with the control group (P < .05). All 86 women in the treatment group stated that acupuncture improved their well-being after treatment. At one month after treatment, 98% of participants in the treatment group reported recovery compared with 24% of the control group participants (P < .001). After treatment, 95% of lactating women in the acupuncture group believed that acupuncture had no significant interference with breast milk production. No adverse effects of acupuncture were reported. All participants in the acupuncture group stated they would choose acupuncture in case of relapse. However, the recurrence rate of sciatica in the acupuncture group (32%) was comparable to that of the control group (35%) at the one-year follow-up interview. DISCUSSION: Compared with bed rest, acupuncture might be an effective and acceptable strategy to relieve symptoms of postpartum sciatica.

PMID- 29569353 TI - Cardioversion of persistent atrial fibrillation is associated with a 24-hour relapse gap: Observations from prolonged postcardioversion rhythm monitoring. AB - BACKGROUND: Many recurrences occur after electrical cardioversion (ECV) of atrial fibrillation (AF). Assessment of extent of remodeling and continuous prolonged rhythm monitoring might reveal actionable recurrence mechanisms. HYPOTHESIS: After ECV of AF specific patterns of arrhythmia recurrence can be distinguished. METHODS: All patients who underwent successful ECV due to persistent AF were included. Tissue velocity echocardiography during AF was performed before ECV to study atrial fibrillatory cycle length and fibrillatory velocity. After ECV, the heart rhythm of all patients was monitored 3 times daily during 4 weeks, and timing of recurrence was noted. RESULTS: In total, 50 patients (68% male) were included; mean age was 68 +/- 9 years. Median duration of the current AF episode was 102 (range, 74-152) days. Twenty-one (42%) patients showed recurrence of persistent AF. No recurrences occurred during the first 24 hours. There were no differences in clinical characteristics between patients with or without recurrence of AF. However, patients with early recurrence of AF had significantly higher precardioversion wall-motion velocity compared with patients who remained in sinus rhythm (2.8 [1.6-3.6] vs 1.4 [0.9-3.3] cm/s; P = 0.017), whereas atrial fibrillatory cycle length did not differ. CONCLUSIONS: In this study on 50 patients successfully cardioverted for persistent AF, there was a relapse gap of >=24 hours. This phenomenon has not been well appreciated before and offers an AF free window of opportunity for electrocardiographically triggered cardiac imaging or complex electrophysiological procedures. Echocardiographic tissue velocity imaging may visualize atrial remodeling relevant to AF recurrence. PMID- 29569354 TI - Virologic failure and mortality in older ART initiators in a multisite Latin American and Caribbean Cohort. AB - INTRODUCTION: The "greying" of the HIV epidemic necessitates a better understanding of the healthcare needs of older HIV-positive adults. As these individuals age, it is unclear whether comorbidities and their associated therapies or the ageing process itself alter the response to antiretroviral therapy (ART). In this study, HIV treatment outcomes and corresponding risk factors were compared between older ART initiators and those who were younger using data from the Caribbean, Central and South America Network for HIV Epidemiology (CCASAnet). METHODS: HIV-positive adults (>=18 years) initiating ART at nine sites in Argentina, Brazil, Chile, Haiti, Honduras, Mexico and Peru were included. Patients were classified as older (>=50 years) or younger (<50 years) based on age at ART initiation. ART effectiveness was measured using three outcomes: death, virologic failure and ART treatment modification. Cox regression models for each outcome compared risk between older and younger patients, adjusting for other covariates. RESULTS: Among 26,311 patients initiating ART between 1996 and 2016, 3389 (13%) were >=50 years. The majority of patients in both >=50 and <50 age groups received a non-nucleoside reverse transcriptase inhibitor-based regimen (89% vs. 87%), did not have AIDS at baseline (63% vs. 62%), and were male (59% vs. 58%). Older patients had a higher risk of death (adjusted hazard ratio (aHR) 1.64; 95% confidence intervals (CI): 1.48 to 1.83) and a lower risk of virologic failure (aHR: 0.73; 95% CI: 0.63 to 0.84). There was no difference in risk of ART modification (aHR: 1.00; 95% CI: 0.94 to 1.06). Risk factors for death, virologic failure and treatment modification were similar for each group. CONCLUSIONS: Older age at ART initiation was associated with increased mortality and decreased risk of virologic failure in our cohort of more than 26,000 ART initiators in Latin America and the Caribbean. To the best of our knowledge this is the first study from the region to evaluate ART outcomes in this growing and important population. Given the complexity of issues related to ageing with HIV, a greater understanding is needed in order to properly respond to this shifting epidemic. PMID- 29569355 TI - Vitamin D status, enterovirus infection, and type 1 diabetes in Italian children/adolescents. AB - At the time of the clinical onset of type 1 diabetes (T1D), we investigated 82 pediatric cases in parallel with 117 non-diabetic controls matched by age, geographic area, and time of collection. The occurrence of an enteroviral infection was evaluated in peripheral blood using a sensitive method capable of detecting virtually all human enterovirus (EV) types. While non-diabetic controls were consistently EV-negative, 65% of T1D cases carried EVs in blood. The vitamin D status was assessed by measuring the concentration of 25-hydroxyvitamin D [25(OH)D] in serum. Levels of 25(OH)D were interpreted as deficiency (<=50 nmol/L), insufficiency (52.5-72.5 nmol/L), and sufficiency (75-250 nmol/L). In T1D cases, the median serum concentration of 25(OH)D was 54.4 +/- 27.3 nmol/L vs 74.1 +/- 28.5 nmol/L in controls (P = .0001). Diabetic children/adolescents showed deficient levels of vitamin D 25(OH)D (ie, 72.5 nmol/L) in 48.8% cases vs 17.9% in non-diabetic controls (P = .0001). Unexpectedly, the median vitamin D concentration was significantly reduced in virus-positive vs virus-negative diabetics (48.2 +/- 22.5 vs 61.8 +/- 31.2 nmol/L; P = .015), with deficient levels in 58.5% vs 31.0%, respectively. Thus, at the time of clinical onset, EV positive cases had reduced vitamin D levels compared with EV-negative cases. This could indicate either that the virus-negative children/adolescents had been hit by a non-infectious T1D-triggering event, or that children/adolescents with proper levels of vitamin D had been able to rapidly clear the virus. Thus, it would be important to assess whether adequate vitamin D supplementation before or during the prediabetic phase of T1D may counteract the diabetogenic potential of infectious pathogens. PMID- 29569356 TI - Metallothermic Reduction of Silica Nanoparticles to Porous Silicon for Drug Delivery Using New and Existing Reductants. AB - In this study, the influence of metals (Mg, Al, and Ca) and reaction conditions (time, temperature, and metal grain size) on the metallothermic reduction of Stober silica nanoparticles (NPs) to form porous Si has been explored. Mg metal was found to be an effective reducing agent even at temperatures below its melting point; however, it also induced a high degree of structural damage and morphology change. Al was effective in reducing silica NPs only at its melting point or above, but the resulting particles retained a higher degree of structural morphology as compared to those reduced using Mg. Ca was found to be ineffective in reducing silica. A new reductant, a mixture of 70 % Mg and 30 % Al, was found to induce the least amount of morphology change, and the reactions proceeded at a temperature (450 degrees C) lower than those required with Mg or Al individually. Furthermore, porous Si NPs obtained using Mg, Al, and the mixture of 70 % Mg and 30 % Al as reductants have been investigated as carriers for ibuprofen loading and release. Porous Si obtained from reductions with Mg and the Mg/Al mixture showed higher drug loading and a sustained drug release profile, whereas porous Si obtained from Al reduction had lower loading and showed a conventional release profile over 24 h. PMID- 29569357 TI - Postpartum Depressive Symptoms: Gestational Weight Gain as a Risk Factor for Adolescents Who Are Overweight or Obese. AB - INTRODUCTION: Obesity is a risk factor for adverse physical health outcomes during pregnancy. Much less is known about the association between obesity and maternal mental health. Evidence suggests that prenatal depression is associated with excessive weight gain during pregnancy and that this relationship may vary according to pregravid body mass index (BMI). Young women may be particularly vulnerable to postpartum depression. The objective of this study is to examine the association between prepregnancy BMI, gestational weight gain, and postpartum depressive symptoms among adolescents. METHODS: Participants were 505 pregnant adolescents aged 14 to 21 years followed during pregnancy and 6 months postpartum. Data were collected via interviews and medical record abstraction. Multilevel linear mixed models were used to test the association between excessive gestational weight gain as defined by National Academy of Medicine Guidelines and postpartum depressive symptoms measured via the validated Center for Epidemiologic Studies Depression (CES-D) scale. Analyses controlled for sociodemographic factors (maternal age, race, ethnicity, relationship status), health behaviors (nutrition, physical activity), prenatal depressive symptoms, and postpartum weight retention. RESULTS: Prepregnancy BMI was classified as follows: 11% underweight, 53% healthy weight, 19% overweight, and 18% obese. One half (50%) of participants exceeded recommended guidelines for gestational weight gain. Adolescents with excessive gestational weight gain who entered pregnancy overweight or obese had significantly higher postpartum depressive symptoms (beta, 2.41; SE, 1.06 vs beta, 2.58; SE, 1.08, respectively; both P < .05) compared with those with healthy prepregnancy BMI and appropriate gestational weight gain. Adolescents who gained gestational weight within clinically recommended guidelines were not at risk for increased depressive symptoms. DISCUSSION: Adolescents who enter pregnancy overweight or obese and experience excessive weight gain may be at increased risk for postpartum depressive symptoms. Health care providers should offer preventive interventions during pregnancy and the interconceptional period to support healthy weight gain and safeguard women's mental health. PMID- 29569358 TI - Prefrontal cortex NG2 glia undergo a developmental switch in their responsiveness to exercise. AB - Aerobic exercise is known to influence brain function, e.g., enhancing executive function in both children and adults, with many of these influences being attributed to alterations in neurogenesis and neuronal function. Yet oligodendroglia in adult brains have also been reported to be highly responsive to exercise, including in the prefrontal cortex (PFC), a late myelinating region implicated in working memory. However, whether exercise affects oligodendroglia or myelination in juveniles, either in the PFC or in other brain regions, remains unknown. To address this, both juvenile and young adult mice were provided free access to running wheels for four weeks followed by an analysis of oligodendrocyte development and myelination in the PFC and the corpus callosum, a major white matter tract. Working memory and PFC NG2+ cell development were both affected by exercise in juvenile mice, yet surprisingly these exercise-mediated effects were distinct in juveniles and young adults. In the PFC, NG2+ cell proliferation was increased in exercising juveniles, but not young adults, whereas newly-born oligodendrocyte production was increased in exercising young adults, but not juveniles. Although no overall changes in myelin genes were found, elevated levels of Monocarboxylate Transporter 1, a glial lactate transporter important during active myelination, were found in the PFC of exercising young adults. Overall our findings reveal that long-term exercise modulates PFC glial development and does so differentially in juvenile and young adult mice, providing insight into the cellular responses that may underlie cognitive benefits to teenagers and young adults in response to exercise.

AB - We have performed three distinct plasma enhanced chemical vapor deposition procedures that can be widely and consistently used in commercially available plasma systems to modify the surface of hydrocarbon-based biomaterials such as polypropylene. In particular, we have evaluated the feasibility of these procedures to provide consistent and stable charged substrates to perform layer by-layer (LbL) coatings. Surface characterization of both plasma and LbL coatings were done using X-ray photoelectron spectroscopy, attenuated total reflection Fourier transform infrared spectroscopy, contact angle measurements and surface staining. Results showed successful surface grafting of functional groups in all plasma procedures that led to increased hydrophilicity and uniform LbL coatings with different efficiencies.

AB - Women with fibroids have a notably high hypertension risk. However, adjusted data regarding other cardiovascular disease (CVD) risk factors are scarce. In this cross-sectional study, CVD risk factors, hemodynamic parameters, and asymptomatic organ damage were analyzed between women with uterine fibroids and controls in a multi-ethnic population. In total, 104 women with self-reported fibroids and 624 controls were included. Women with fibroids had significantly higher odds to have hypertension (OR 3.4; 95% CI 2.2-5.2), diabetes (1.7; 1.0-2.9), and hypercholesterolemia (1.8; 1.1-3.2). After adjustment for confounders, only the odds ratio for hypertension was significant (1.8; 1.1-3.1). Asymptomatic organ damage occurred significantly more often in women with fibroids (66.7%; 95% CI 55.8%-77.6% vs 42.9%; 38.0-47.8 in controls), especially in the younger age group (respectively 48.5%; 31.1%-65.9% vs 22.1%; 17.0-27.2). In this study, women with fibroids had a remarkably high hypertension risk compared to controls, with more asymptomatic organ damage, in particular young women.

AB - INTRODUCTION: The purpose of this qualitative meta-synthesis was to understand the labor and birth experiences of immigrant women in countries of resettlement who have a history of female genital cutting (FGC), also known as female genital mutilation or female circumcision. METHODS: We used a meta-ethnography approach to synthesize the literature on this topic. We searched PubMed, Embase, Web of Science, CINAHL, PsycINFO, and Sociological Abstracts databases from inception to May 2016 using the search terms female genital cutting, female circumcision, clitorectomy, clitoridectomy, pharaonic circumcision, genital circumcision, female genital mutilation, infibulation, and deinfibulation. Our inclusion criteria were 1) peer-reviewed, original qualitative research; 2) focused on populations affected by FGC or their health care providers; 3) conducted in a country where FGC is not documented as an indigenous practice; 4) English language; and 5) included a description of postmigratory labor and birth experiences of women affected by FGC. Fourteen articles were included. RESULTS: Two new syntheses emerged from our sample of studies including African immigrant women primarily resettled in Europe and the United States. First, birth after FGC in the context of resettlement included pain and anxiety, and has the potential to retraumatize. Second, while women experienced nostalgia for familiar traditions and perceived disrespect in their new setting, they questioned traditions, including the role of FGC, in their and their daughters' lives. DISCUSSION: The negative birth experiences of women affected by FGC highlight the need to improve care for this population. Health care professionals can serve as a source of support for women affected by FGC by acknowledging and addressing FGC in their care and actively listening to their perspectives and concerns.

AB - The peripheral somatosensory system overproduces neurons early in development followed by a period of cell death during final target innervation. The decision to survive or die in somatosensory neurons of the dorsal root ganglion (DRG) is mediated by target-derived neurotrophic factors and their cognate receptors. Subsets of peripheral somatosensory neurons can be crudely defined by the neurotrophic receptors that they express: peptidergic nociceptors (TrkA+), nonpeptidergic nociceptors (Ret+), mechanoreceptors (Ret+ or TrkB+), and proprioceptors (TrkC+). A direct comparison of early developmental timing between these subsets has not been performed. Here we characterized the accumulation and death of TrkA, B, C, and Ret+ neurons in the DRG as a function of developmental time. We find that TrkB, TrkC, and Ret-expressing neurons in the DRG complete developmental cell death prior to TrkA-expressing neurons. Given the broadly defined roles of the neurotrophin receptor p75NTR in augmenting neurotrophic signaling in sensory neurons, we investigated its role in supporting the survival of these distinct subpopulations. We find that TrkA+, TrkB+, and TrkC+ sensory neuron subpopulations require p75NTR for survival, but proliferating progenitors do not. These data demonstrate how diverging sensory neurons undergo successive waves of cell death and how p75NTR represses the magnitude, but not developmental window of this culling.

PMID- 29569364 TI - Ambulatory blood pressure in relation to oxygen desaturation index as simultaneously assessed by nighttime finger pulse oximetry at home. AB - We investigated the relationship between ambulatory blood pressure (BP) and oxygen desaturation index (ODI), while accounting for pulse rate and age. ODI was assessed by overnight finger pulse oximetry in 2342 participants on the day of ambulatory BP monitoring, and calculated as the number of desaturation episodes per sleeping hour. Both BP and pulse rate increased significantly (P <= .006) from normal (< 5 events/h) to mildly (5-14), moderately (15-30), and severely (>= 30 events/h) elevated ODI. The association for BP was substantially attenuated by accounting for pulse rate (partial r2 from .003-.012 to .002-.006). In adjusted analysis, the associations of 24-hour diastolic BP and 24-hour pulse rate with ODI were dependent on age (P <= .0001) and only significant in younger subjects (< 60 years, P <= .0001). In conclusion, the association between ambulatory BP and ODI was partially mediated by pulse rate, a measure of sympathetic activity, and was more prominent in younger subjects. PMID- 29569365 TI - Structural effects of point mutations in proteins. AB - A structural database of 11 families of chains differing by a single amino acid substitution has been built. Another structural dataset of 5 families with identical sequences has been used for comparison. The RMSD computed after a global superimposition of the mutated protein on each native one is smaller than the RMSD calculated among proteins of identical sequences. The effect of the perturbation is very local, and not necessarily the highest at the position of the mutation. A RMSD between mutated and native proteins is computed over a 3 residue or a 7-residue window at each position. To separate the effects of structural fluctuations due to point mutations from other sources, pair RMSD have been translated into P values which themselves are included in a score called P RANK. This score allows highlighting small backbone distortions by comparing these RMSD between mutated and native positions to the RMSD at the same positions in the absence of a mutation. It results from the P-RANK that 38% of all mutations produce a significant effect on the displacement. When compared with a random distribution of RMSD at un-mutated positions, we show that, even if the RMSD is greater when the mutation is in loops than in regular secondary structure, the relative effect is more important for regular secondary structures and for buried positions. We confirm the absence of correlation between RMSD and the predicted variation of free energy of folding but we found a small correlation between high RMSD and the error in the prediction of DeltaDeltaG. PMID- 29569366 TI - Assessment of recording bias in pregnancy studies using health care databases: An application to neurologic conditions. AB - BACKGROUND: Pre-existing conditions are imperfectly recorded in health care databases. We assessed whether pre-existing neurologic conditions (epilepsy, multiple sclerosis [MS]) were differentially recorded in the presence of major obstetric outcomes (Caesarean delivery, preterm delivery, preeclampsia) in delivery records. We also evaluated the impact of differential recording on measures of frequency and association between the conditions and outcomes. METHODS: The 2011-2014 Truven Health MarketScan(r) Commercial Claims Dataset was used to identify pregnancies. We calculated the relative recording of epilepsy and MS at delivery hospitalization compared with a 270-day pre-delivery window both overall and by the presence of major obstetric outcomes. We estimated risk ratios for the association between epilepsy and MS with the outcomes for each ascertainment window. RESULTS: We identified 909 065 pregnancies in women continuously enrolled from 270-days before the delivery date. Of women with epilepsy identified in the pre-delivery window, 73% had the condition coded at delivery. For MS, the proportion was 60%. MS recording at delivery did not vary by obstetric outcomes, however, delivery-coded epilepsy was less likely confirmed in the pre-delivery window in the presence of preeclampsia. Generally, the period of ascertainment did not meaningfully impact risk ratios, however, the risk ratio for preeclampsia associated with epilepsy was 1.67 (95% CI 1.47, 1.90) when epilepsy was ascertained at delivery and 1.26 (95% CI 1.07, 1.48) when epilepsy was ascertained in the pre-delivery window (heterogeneity, P = .007). CONCLUSIONS: Ascertainment of epilepsy and MS in delivery hospitalization records underestimated prevalence. However, the window of recording generally did not impact risk ratio estimates of associations with obstetric outcomes.

AB - Graphite carbon nitride (g-C3 N4 ) is a promising candidate for photocatalytic hydrogen production, but only shows moderate activity owing to sluggish photocarrier transfer and insufficient light absorption. Herein, carbon quantum dots (CQDs) implanted in the surface plane of g-C3 N4 nanotubes were synthesized by thermal polymerization of freeze-dried urea and CQDs precursor. The CQD implanted g-C3 N4 nanotubes (CCTs) could simultaneously facilitate photoelectron transport and suppress charge recombination through their specially coupled heterogeneous interface. The electronic structure and morphology were optimized in the CCTs, contributing to greater visible light absorption and a weakened barrier of the photocarrier transfer. As a result, the CCTs exhibited efficient photocatalytic performance under light irradiation with a high H2 production rate of 3538.3 MUmol g-1 h-1 and a notable quantum yield of 10.94 % at 420 nm.

AB - We present optimally reconstructed three-dimensional computed tomography images of left ventricular outflow obstruction, comprehensive left ventriculography, and comparable intraoperative transesophageal echocardiography, as well as serial operative pictures, to facilitate the understanding of live-heart anatomy of hypertrophic obstructive cardiomyopathy. As shown in this case, detailed morphological analysis around the left ventricular outflow tract using preoperative computed tomography would be feasible and useful. The present case highlights the importance of obtaining complete three-dimensional information present in the acquired computed tomography dataset because computed tomography is not entirely noninvasive or free of radiation exposure and contrast material.

AB - Three new compounds (1 - 3), including two euphane type triterpenes, 24,24 dimethoxy-25,26,27-trinoreuphan-3beta-ol (1) and (24S)-24-hydroperoxyeupha-8,25 dien-3beta-ol (2), and an ent-atisine diterpene, ent-atisane-3alpha,16alpha,17 triol (3), were isolated from an acetone extract of the stems of Euphorbia antiquorum, together with eight known diterpenes (4 - 11). The structures of compounds (1 - 11) were elucidated using NMR and MS spectroscopic methods. Compound 7 showed moderate activity against HIV-1 replication in vitro (EC50 = 1.38 MUm).

PMID- 29569371 TI - Molecular and functional characterization of three odorant binding proteins from the oriental fruit moth Grapholita molesta (Busck) (Lepidoptera: Tortricide). AB - Odorant binding proteins (OBPs) act in recognizing odor molecules and their most well-studied functions are transporting odors across the sensillum lymph to olfactory receptor neurons within the insect antennal sensillum. The adults of Grapholita molesta highly depend on olfactory cues in locating host plants and selecting oviposition sites, in which OBPs play an important role in perceiving and recognizing host plant volatiles. Exploring the physiological function of OBPs could facilitate our understanding of their importance in insects' chemical communication. In this study, three OBP genes were cloned and named GmolOBP4, GmolOBP5, and GmolOBP10. Quantitative real-time PCR results indicated that GmolOBP4 and GmolOBP10 were predominantly expressed in adult antennae and GmolOBP5 was expressed in multiple tissues, including head, legs, and wings in addition to antennae. The binding affinities of the three recombinant GmolOBPs (rGmolOBPs) with four sex pheromone components and twenty-nine host plant volatiles were measured using 1-N-Phenyl-naphthylamine as a fluorescence probe. The three rGmolOBPs exhibited specific binding properties to potential ligands, GmolOBP4 and GmolOBP10 bound to minor sex pheromone components, such as (Z)-8 dodecenyl alcohol and dodecanol, respectively. rGmolOBP4 showed intermediate binding ability with hexanal, benzyl alcohol, and pear ester, rGmolOBP5 had a weak affinity for benzaldehyde, pear ester and, methyl jasmonate, and rGmolOBP10 showed strong binding capacity toward hexanol, decanol, and alpha-ocimene. We speculate that the GmolOBP4 and GmolOBP10 have dual functions in perception and recognition of host plant volatiles and sex pheromone components, while GmolOBP5 may serve other function(s).

AB - : In this study, solid lipid nanoparticles containing Eugenia caryophyllata essential oil (SLN-EO) were prepared by high-shear homogenization and ultrasound methods, and used to eradicate pathogens. SLN formulations were evaluated for their size, zeta potential and encapsulation efficacy (EE). The morphological and thermal properties of the formulations were analysed by transmission electron microscopy (TEM) and differential scanning calorimetry methods. The lead formulations were chosen and tested with minimum inhibitory concentration (MIC), MBC and time-kill methods to investigate the antimicrobial activity against Salmonella typhi, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. The particle size of three final formulations were 397 +/- 10.1, 786.9 +/- 11 and 506.4 +/- 22 nm respectively. The zeta potential of all formulations was negative values. The size of the formulations was slightly increased during 3 months storage at 25 degrees C. The TEM imaging showed that formulation had spherical shape. The EE of EO was estimated approximately 70%. MIC and MCC values of SLN-EO were lower than those of the oil alone. The time-kill studies showed that SLN-EO was either equivalent to or better than EO (P-value <0.05). The results of this study highlighted the effectiveness of SLN formulations against human pathogens. SIGNIFICANCE AND IMPACT OF THE STUDY: Microbial resistance to antibiotics is a major problem in the treatment of diseases. Therefore, overcoming antimicrobial resistance is an urgent need. Drug delivery via nanoparticles and applying natural products are promising approaches to reduce microbial resistance. This study is designed to evaluate the antimicrobial activity of solid lipid nanoparticles (SLN) containing Eugenia caryophyllata essential oil (EO) against human pathogens. The results indicated that the antimicrobial activity of EO was remarkably enhanced when encapsulated in SLN. PMID- 29569374 TI - Overexpression of WD repeat domain 5 associates with aggressive clinicopathological features and unfavorable prognosis in head neck squamous cell carcinoma. AB - BACKGROUND: WD repeat domain 5 (WDR5), a core member of Mixed lineage leukemia (MLL) and SET1 histone H3 lysine 4 (H3K4) methyltransferase complexes, is involved in multiple biological and pathological processes. Its deregulation in cancer and pro-tumorigenic roles has been increasingly appreciated. However, the expression pattern of WDR5 and its biological functions in head neck squamous cell carcinoma (HNSCC) have not been well established. METHODS: The expression of WDR5 mRNA in HNSCC was determined by data mining and interrogation using publicly available databases. Its protein expression was measured by immunohistochemistry in a retrospective cohort of primary HNSCC samples. Moreover, the associations between WDR5 expression and various clinicopathological parameters and patient survival were assessed. The pro-tumorigenic roles of WDR5 in HNSCC were further delineated in vitro by loss-of-function assay. RESULTS: Our bioinformatics analyses revealed that WDR5 mRNA was significantly overexpressed in 3 HNSCC cohorts. WDR5 protein was markedly upregulated in HNSCC samples as compared to normal counterparts and its overexpression significantly associated with large tumor size, advanced clinical stage (chi-square test, P = .048, .006) and reduced overall and disease-free survival (Kaplan-Mier analyses, Log-rank test, P = .0137, .0154). Univariate and multivariate survival analyses further revealed WDR5 protein abundance as an independent prognostic factor for patients' overall survival. Moreover, WDR5 knockdown significantly inhibited cell proliferation, migration and invasion, and induced cell apoptosis in HNSCC cells. CONCLUSIONS: Our findings reveal that WDR5 is aberrantly overexpressed in HNSCC and associates with aggressiveness and unfavorable prognosis, thus representing a novel diagnostic and prognostic biomarker for HNSCC. PMID- 29569375 TI - Roflumilast Usage from 2010 to 2016: A Danish Nationwide Drug Utilization Study. AB - Roflumilast, a phosphodiesterase-4-inhibitor, is marketed as add-on treatment to inhaled bronchodilators and corticosteroids in COPD patients with frequent exacerbations. Although marketed since 2010, usage pattern of roflumilast for an entire nation has not previously been explored. This study aimed to estimate the total utilization of roflumilast in Denmark during 2010 to 2016, using the Danish nationwide health registers. We identified 1573 individuals (47% males) who used roflumilast during the study period, of whom 705 (45%) redeemed only one prescription. Of all patients initiating roflumilast, 67% discontinued treatment within the first year. The rate of treatment initiation decreased 73% from 2011 (7.5/100,000 person-years) to 2016 (2.0/100,000 person-years) concurrent with a stable prevalence of 3.0-4.0/100,000 persons throughout the study period. The median duration of roflumilast use was 76 days. Patients with severe comorbidity tended to exhibit a lower degree of early discontinuation (Charlson Comorbidity Index 3+: odds ratio [OR]: 0.59; 95% confidence interval [CI] 0.33-1.04), as well as patients with a COPD-related admission within a year prior to roflumilast initiation (OR 0.62; 95% CI 0.49-0.80). The decreasing incidence and high level of early roflumilast discontinuation could be due to lack of benefit, a low awareness of romiflulast's indication among physicians, secondary to a challenging prescribing procedure or to adverse effects. PMID- 29569376 TI - Contrasting features of childhood and adolescent melanomas. AB - BACKGROUND/OBJECTIVES: Melanoma in children and adolescents is uncommon, and there are limited data on pediatric outcomes. Several studies have shown comparable survival rates in children and adults, but other research demonstrates that prepubescent children have more favorable outcomes. This study aims to compare childhood and adolescent melanoma. METHODS: Retrospective cohort study of children who received a melanoma diagnosis at the Massachusetts General Hospital between January 1, 1995, and December 21, 2016. Childhood melanoma is defined as disease occurring in patients younger than 11 years old, and adolescent melanoma is defined as disease occurring in patients 11 to 19 years old. Patients diagnosed with ocular melanoma and borderline tumors of uncertain malignant potential were excluded. This analysis compares clinical, histopathologic, and outcome characteristics of childhood and adolescent melanoma. RESULTS: Thirty-two children with melanoma were identified (12 children, 20 adolescents). The spitzoid melanoma subtype was significantly more common in children (6/12) than adolescents (2/20) (P = .01). Four adolescents and no children with melanoma died from melanoma, and survival was significantly different between the age groups (P = .04). Median follow-up time for survivors was 3.6 years. CONCLUSIONS: These results suggest that children and adolescents present with different melanoma subtypes and that adolescents have a more aggressive disease course than children. PMID- 29569378 TI - Rates of myocardial infarction and stroke in patients initiating treatment with SGLT2-inhibitors versus other glucose-lowering agents in real-world clinical practice: Results from the CVD-REAL study. AB - The multinational, observational CVD-REAL study recently showed that initiation of sodium-glucose co-transporter-2 inhibitors (SGLT-2i) was associated with significantly lower rates of death and heart failure vs other glucose-lowering drugs (oGLDs). This sub-analysis of the CVD-REAL study sought to determine the association between initiation of SGLT-2i vs oGLDs and rates of myocardial infarction (MI) and stroke. Medical records, claims and national registers from the USA, Sweden, Norway and Denmark were used to identify patients with T2D who newly initiated treatment with SGLT-2i (canagliflozin, dapagliflozin or empagliflozin) or oGLDs. A non-parsimonious propensity score was developed within each country to predict initiation of SGLT-2i, and patients were matched 1:1 in the treatment groups. Pooled hazard ratios (HRs) and 95% CIs were generated using Cox regression models. Overall, 205 160 patients were included. In the intent-to treat analysis, over 188 551 and 188 678 person-years of follow-up (MI and stroke, respectively), there were 1077 MI and 968 stroke events. Initiation of SGLT-2i vs oGLD was associated with a modestly lower risk of MI and stroke (MI: HR, 0.85; 95%CI, 0.72-1.00; P = .05; Stroke: HR, 0.83; 95% CI, 0.71-0.97; P = .02). These findings complement the results of the cardiovascular outcomes trials, and offer additional reassurance with regard to the cardiovascular effects of SGLT-2i, specifically as it relates to ischaemic events. PMID- 29569377 TI - Immune regulation by microbiome metabolites. AB - Commensal microbes and the host immune system have been co-evolved for mutual regulation. Microbes regulate the host immune system, in part, by producing metabolites. A mounting body of evidence indicates that diverse microbial metabolites profoundly regulate the immune system via host receptors and other target molecules. Immune cells express metabolite-specific receptors such as P2X7 , GPR41, GPR43, GPR109A, aryl hydrocarbon receptor precursor (AhR), pregnane X receptor (PXR), farnesoid X receptor (FXR), TGR5 and other molecular targets. Microbial metabolites and their receptors form an extensive array of signals to respond to changes in nutrition, health and immunological status. As a consequence, microbial metabolite signals contribute to nutrient harvest from diet, and regulate host metabolism and the immune system. Importantly, microbial metabolites bidirectionally function to promote both tolerance and immunity to effectively fight infection without developing inflammatory diseases. In pathogenic conditions, adverse effects of microbial metabolites have been observed as well. Key immune-regulatory functions of the metabolites, generated from carbohydrates, proteins and bile acids, are reviewed in this article. PMID- 29569379 TI - Risk factors for blood stream infections in multiple myeloma: A population-based study of 1154 patients in Denmark. AB - OBJECTIVES: Multiple myeloma (MM) patients are at high risk of developing infections. The risk factors for blood stream infections (BSI) in MM patients are, however, less described. The aim of this study was to analyze the epidemiology of and risk factors for BSI in an unselected MM population. METHODS: Nationwide Danish MM data of 1154 patients diagnosed from 2010 to 2013 were linked with nationwide data on blood cultures (BCs; from 2010 to 2016) to assess the peak period of having a BC taken and BC positive for pathogenic microorganisms. RESULTS: The highest number of BC was taken in the period from day -30 to day +180 from date of MM diagnosis. Risk factors for having a BC sampling within the peak period were as follows: immunoparesis (HR 1.5 [1.1-2.1]; P = .007), ISS-III (HR 1.3 [1.0-1.7]; P = .035), high creatinine (HR 1.4 (1.0 2.0); P = .046), and high lactate dehydrogenase (LDH) (HR 2.8 (1.6-4.7; P < .001). Risk factors for positive BC during the peak period were ISS-III (HR 2.0 (1.1-3.7); P = .023) and high LDH (HR 3.4 [1.1-10.3]; P = .028). CONCLUSIONS: Our results show that MM patients with aggressive disease presentation are at the highest risk of developing BSI. Furthermore, our study implies that MM is diagnosed in relation to a serious infection for a large number of patients. PMID- 29569380 TI - Modeling Missed Care: Implications for Evidence-Based Practice. AB - BACKGROUND: There is a growing nursing literature that views missed care as an inevitable consequence of work intensification associated with the rationing of nursing and material resources available to deliver care. Global studies recognize that missed care is now ubiquitous, although studies tend to be conducted in one region, rather than nationwide. This study seeks to understand the Australian context of missed care. AIMS: To explore self-reported reasons for missed care and to identify the main factors for predicting missed care within a sample of Australian nurses and midwives working in public and private hospitals in New South Wales, Victoria, Tasmania, and South Australia. METHODS: A nonexperimental, descriptive method using Kalisch's (2006) MISSCARE survey was used. Responses from 1,195 nursing and midwifery staff with differing qualifications, English language skills, and Australian employment settings were analyzed using Rasch analysis and then modeled using the Structural Equation Modeling. RESULTS: The frequency of missed care on the morning shift directly impacted on higher priority care missed during the afternoon shift. Staff skill mix imbalances and perceived inadequacy of staff numbers for the work demands further exacerbated all aspects of care during afternoon shifts. Other major factors associated with missed care were the different clinical work settings and staff to patient ratios. LINKING EVIDENCE TO ACTION: The incidences, types, and reasons behind missed care are a multidimensional construct which can be predicted when known significant factors behind missed care are simultaneously accounted for. PMID- 29569381 TI - An exploration of predictors of children's nurses' attitudes, knowledge, confidence and clinical behavioural intentions towards children and young people who self-harm. AB - AIMS AND OBJECTIVES: To explore the potential predictors of children's nurses' attitudes, knowledge and confidence towards caring for children and young people admitted to hospital with self-harm. BACKGROUND: Admissions to paediatric inpatient settings for individuals who have self-harmed are growing. Limited previous research suggests that nurses have mixed attitudes towards people who have self-harmed and potentially lack the confidence to provide effective care. There is a specific paucity of research in this area for children's nurses. DESIGN: A cross-sectional descriptive survey was used to gather data for exploration of variables associated with attitudes, confidence, knowledge and clinical behavioural intentions of 98 registered children's nurses in a single tertiary children's hospital, colocated in a large acute NHS Trust in the UK. METHODS: Data were collected over a 4 weeks in 2015, using an online survey tool. The predictive effect of several demographic variables was tested on the outcomes of attitudes, knowledge, confidence and behavioural intentions, which were collected using relevant, previously used outcome measures. RESULTS: Increased experience was found to be associated with improved attitudes relating to negativity. Previous training in caring for children who had self-harmed was found to be associated with improved attitudes around perceived effectiveness of their care. Higher academic qualifications and having undertaken previous training on self-harm were each found to be associated with increased knowledge of self-harm, and increased age was associated with reduced knowledge of self harm. CONCLUSIONS: This study provides an initial exploration of variables associated with attitudes, knowledge, confidence and behaviour intentions of registered children's nurses in relation to caring for CYP who have self-harmed. RELEVANCE TO CLINICAL PRACTICE: Targeted training on caring for CYP who have self harmed should be considered as a component of continuing education for registered children's nurses in the UK to improve the experience and outcomes for this patient group. PMID- 29569382 TI - Case of lamotrigine-induced drug adverse reaction under tocilizumab treatment with clinical and virological features of drug-induced hypersensitivity syndrome. AB - The pathological mechanisms and immunological kinetics of drug-induced hypersensitivity syndrome (DIHS), including the relevance of interleukin (IL)-6, remain unclear. We report a case of drug adverse reaction that does not fulfill the diagnostic criteria of DIHS but mimics its characteristic features. Because the patient was under anti-IL-6 therapy at the onset, some symptoms typically seen in DIHS were absent, such as fever and leukocyte count abnormalities. However, the characteristic features of DIHS were clearly observed in the subsequent course, including the repeated recurrence of skin rash, prolonged liver dysfunction and reactivation of herpes viruses. This case suggested that IL 6 role at the onset is not a main factor to determine the subsequent pathomechanism of DIHS and attention should be paid to the preceding therapy for achieving accurate diagnosis. PMID- 29569383 TI - Inter-disciplinary cooperation in a physician-staffed emergency medical system. AB - BACKGROUND: On-scene management of pre-hospital emergencies is often inter disciplinary, involving ground-emergency medical services (EMS), police- and fire services, and in Norway general practitioners on-call. This can also be supplemented by physician-staffed EMS (P-EMS), utilizing helicopters or rapid response vehicles. We hypothesized that P-EMS cooperates extensively with other emergency services, and therefore the primary aim of this study was to investigate the fraction of inter-disciplinary cooperation between P-EMS and other emergency services. METHODS: Retrospective, observational study of primary pre-hospital missions with patient contact performed at a Norwegian P-EMS base from 01.01.06 to 31.12.15. Descriptive statistics, comparisons using Student's t test, and chi-squared test for trend were applied. RESULTS: Inter-disciplinary cooperation occurred in 94.3% of the 8580 missions, of which physician-staffed EMS cooperated with ground EMS in 92.4%, general practitioner 32.9%, police service 11.6% and fire service 11.8%. Trauma constituted 34.4 and cardiac arrest 14.1% of missions. The mean National Advisory Committee for Aeronautics score was 4.21 (95% Confidence Interval 4.18-4.24). There was an overall decrease in cooperation with general practitioners and the police service (P < 0.001). During helicopter missions, we reported a decrease in general practitioner cooperation compared to an increase during rapid response car missions (P < 0.001). In cardiac arrest cases, cooperation with both general practitioners and the fire service increased (P < 0.001). CONCLUSION: Physician-staffed EMS cooperates extensively with other professional emergency services, especially ground-EMS. On scene cooperation with general practitioners decreased, whereas there was an increased cooperation with the fire service in a "first-responder" role during cardiac arrest missions. PMID- 29569385 TI - Taste impairment in chronic rhinosinusitis. AB - BACKGROUND: Though many patients with chronic rhinosinusitis (CRS) describe disturbances in smell and taste, there have been no studies specifically assessing taste impairment in CRS. This study sought to objectively assess taste dysfunction in CRS patients and determine whether taste impairment correlates with olfactory dysfunction. Additionally, this investigation sought to determine the impact of taste dysfunction on quality of life (QOL) in CRS and identify the clinical factors that influence taste. METHODS: Sixty-eight CRS patients were prospectively enrolled and completed several QOL surveys in relation to taste, smell, overall sinus-specific QOL, and depression. Validated taste strips were used to determine gustatory dysfunction pertaining to sweet, sour, salty, and bitter. Olfactory testing was assessed using the Sniffin' Sticks Test while both Lund-Kennedy and Olfactory Cleft Endoscopy Scoring (OCES) systems were used for endoscopic evaluation. RESULTS: The overall prevalence of dysgeusia was 28%, with scores significantly lower for sour compared to other subgroups. No correlation was observed between taste scores and objective olfactory metrics including olfaction tests and OCES. Taste scores were better in younger patients (r = 0.28, p = 0.02), female patients (p = 0.004), and never smokers compared to former smokers (p = 0.01). Taste scores did not correlate with patient-reported outcome measures or CRS disease severity metrics. CONCLUSION: Taste dysfunction is a common complaint in CRS. This cohort shows prevalence of gustatory loss to be about 28% using ideal normative values. This dysfunction correlated with male gender, smoking history, and older age.

AB - Sex chromosomes are disproportionately involved in reproductive isolation and adaptation. In support of such a "large-X" effect, genome scans between recently diverged populations and species pairs often identify distinct patterns of divergence on the sex chromosome compared to autosomes. When measures of divergence between populations are higher on the sex chromosome compared to autosomes, such patterns could be interpreted as evidence for faster divergence on the sex chromosome, that is "faster-X", barriers to gene flow on the sex chromosome. However, demographic changes can strongly skew divergence estimates and are not always taken into consideration. We used 224 whole-genome sequences representing 36 populations from two Heliconius butterfly clades (H. erato and H. melpomene) to explore patterns of Z chromosome divergence. We show that increased divergence compared to equilibrium expectations can in many cases be explained by demographic change. Among Heliconius erato populations, for instance, population size increase in the ancestral population can explain increased absolute divergence measures on the Z chromosome compared to the autosomes, as a result of increased ancestral Z chromosome genetic diversity. Nonetheless, we do identify increased divergence on the Z chromosome relative to the autosomes in parapatric or sympatric species comparisons that imply postzygotic reproductive barriers. Using simulations, we show that this is consistent with reduced gene flow on the Z chromosome, perhaps due to greater accumulation of incompatibilities. Our work demonstrates the importance of taking demography into account to interpret patterns of divergence on the Z chromosome, but nonetheless provides evidence to support the Z chromosome as a strong barrier to gene flow in incipient Heliconius butterfly species.

AB - The present studies examine whether and how 18-month-olds use informants' accuracy to acquire novel labels for novel objects and generalize them to a new context. In Experiment 1, two speakers made statements about the labels of familiar objects. One used accurate labels and the other used inaccurate labels. One of these speakers then introduced novel labels for two novel objects. At test, toddlers saw those two novel objects and heard an unfamiliar voice say one of the labels provided by the speaker. Only toddlers who had heard the novel labels introduced by the accurate speaker looked at the appropriate novel object above chance. Experiment 2 explored possible mechanisms underlying this difference in generalization. Rather than making statements about familiar objects' labels, both speakers asked questions about the objects' labels, with one speaker using accurate labels and the other using inaccurate labels. Toddlers' generalization of novel labels for novel objects was at chance for both speakers, suggesting that toddlers do not simply associate hearing the accurate label with the reliability of the speaker. We discuss these results in terms of potential mechanisms by which children learn and generalize novel labels across contexts from speaker reliability. PMID- 29569387 TI - A novel functional polymorphism of GSTM3 reduces clear cell renal cell carcinoma risk through enhancing its expression by interfering miR-556 binding. AB - Dysregulation of glutathione-S-transferase M3 (GSTM3) has been related to clear cell renal cell carcinoma (ccRCC) in our former study. GSTM3 plays a pivotal role of detoxification and clearance of reactive oxygen species (ROS) in tumour tissues. This study aimed to examine: (1) the associations between GSTM3 single nucleotide polymorphisms (SNPs) and risk of ccRCC, and (2) the potential molecular mechanism accounting for its effects. 5 SNPs in 3'UTR of GSTM3 were initially genotyped in 329 cases and 420 healthy controls. A SNP-rs1055259 was found to be significantly associated with the susceptibility of ccRCC (OR = 0.59, 95% CI = 0.41-0.92; P = .019). The minor allele of rs1055259 (G allele) was associated with RCC risk. This SNP was predicted to affect microRNA (miR)-556 binding to 3'UTR of GSTM3 mRNA. To determine the functional impact, plasmid constructs carrying different alleles of rs1055259 were created. Compared to rs1055259 A-allele constructs, cells transfected with rs1055259 G-allele construct had higher transcriptional activity and were less responsive to miR-556 changes and gene expression. Elevated GSTM3 expression in G-allele cells was associated with ROS activity and ccRCC development. Taken together, this study indicated that a functional polymorphism of GSTM3 -rs1055259 reduced susceptibility of RCC in the Chinese population. It influenced GSTM3 protein synthesis by interfering miR-556 binding, subsequently suppressed ROS activity and ccRCC progression.

AB - Although interleukin (IL)-33 is a candidate for the aggravation of asthma, the mechanisms underlying antigen-specific IL-33 production in the lung are unclear. Therefore, we analysed the mechanisms in mice. Intra-tracheal administration of ovalbumin (OVA) evoked increases in IL-33 and IL-33 mRNA in the lungs of both non sensitized and OVA-sensitized mice, and the increases in the sensitized mice were significantly higher than in the non-sensitized mice. However, intra-tracheal administration of bovine serum albumin did not increase the IL-33 level in the OVA-sensitized mice. Depletion of neither mast cells/basophils nor CD4+ cells abolished the OVA-induced IL-33 production in sensitized mice, suggesting that the antigen recognition leading to the IL-33 production was not related with either antigen-specific IgE-bearing mast cells/basophils or memory CD4+ Th2 cells. When a fluorogenic substrate-labelled OVA (DQ-OVA) was intra-tracheally administered, the lung cells of sensitized mice incorporated more DQ-OVA than those of non-sensitized mice. The lung cells incorporating DQ-OVA included B cells and alveolar macrophages. The allergic IL-33 production was significantly reduced by treatment with anti-FcgammaRII/III mAb. Depletion of alveolar macrophages by clodronate liposomes significantly suppressed the allergic IL-33 production, whereas depletion of B-cells by anti-CD20 mAb did not. These results suggest that the administered OVA in the lung bound antigen-specific IgG Ab, and then alveolar macrophages incorporated the immune complex through FcgammaRII/III on the cell surface, resulting in IL-33 production in sensitized mice. The mechanisms underlying the antigen-specific IL-33 production may aid in development of new pharmacotherapies. PMID- 29569390 TI - The fragility of statistically significant findings from randomised controlled trials in the urological literature. AB - OBJECTIVES: To use the Fragility Index to evaluate the robustness of statistically significant findings from urological randomised controlled trials (RCTs). MATERIALS AND METHODS: The 'Fragility Index' is defined as the minimum number of patients in one arm of a trial whose status would have to change from 'event' to 'non-event', such that a statistically significant result becomes non significant. We identified all RCTs published in four major urology journals between 2011 and 2015, and we determined the Fragility Index values for those trials reporting statistically significant results of dichotomous outcomes using the Fisher's exact test. RESULTS: In all, 332 RCTs were identified, and 41 studies met the inclusion criteria. The median (interquartile range) Fragility Index was 3 (1, 4.5), indicating that an addition of only three alternate events to one arm of a typical trial would have eliminated its statistical significance. In 27/40 cases (67.5% of cases), the number of patients lost to follow-up was larger than its Fragility Index. CONCLUSIONS: The results of urology RCTs that study dichotomous outcomes and report statistically significant differences between groups are sometimes fragile and depend on few events. Urologists should interpret these RCTs cautiously, particularly when the number of participants lost to follow-up exceeds the Fragility Index. Routine reporting of Fragility Index values alongside P values may provide additional guidance about the robustness of statistically significant findings. PMID- 29569389 TI - Serenoa repens + selenium + lycopene vs tadalafil 5 mg for the treatment of lower urinary tract symptoms secondary to benign prostatic obstruction: a Phase IV, non inferiority, open-label, clinical study (SPRITE study). AB - OBJECTIVE: To compare in a randomised, open-label, non-inferiority clinical study, the efficacy and tolerability of Serenoa repens (SeR) + selenium (Se) + lycopene (Ly) (SeR-Se-Ly) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: From May 2015 to January 2017, 427 patients were enrolled in 21 different centres (International Standard Randomised Controlled Trial Number Register [ISRCTN] 73316039). Inclusion criteria included: age between 50 and 80 years, International Prostate Symptom Score (IPSS) >=12, maximum urinary flow rate (Qmax ) <= 15 mL/s, and post-void residual (PVR) <100 mL. Patients were randomised into two groups in a 2:1 ratio: Group A (SeR-Se-Ly, 1 tablet daily for 6 months) and Group B (tadalafil 5 mg, 1 tablet daily for 6 months). The primary endpoint of the study was the non-inferior variation in the IPSS and Qmax in Group A vs Group B after 6 months of treatment. RESULTS: In all, 404 patients completed the full protocol. When comparing both therapies, Group A was statistically not inferior to Group B considering the median change in IPSS ( 3.0 vs -3.0; P < 0.01), IPSS quality of life (-2.0 vs -2.0; P < 0.05), and Qmax (2.0 vs 2.0 mL/s; P < 0.01). We found statistically significant differences in the increase of at least 3 points in Qmax (38.2% vs 28.1%; P = 0.04) and of at least 30% of Qmax (39.2% vs 27.3%; P < 0.01) in Group A compared to Group B. The percentage of patients with an increase of at least 3 points in the IPSS and a decrease of at least 25% of the IPSS was not statistically different between the two groups. For adverse events, four patients in Group A (1.44%) and 10 in Group B (7.81%) (P < 0.05) reported side-effects. CONCLUSION: We have shown that treatment with SeR-Se-Ly was not inferior to tadalafil 5 mg for improving IPSS and Qmax in men with LUTS. PMID- 29569391 TI - Layer-by-layer buildup of polysaccharide-containing films: Physico-chemical properties and mesenchymal stem cells adhesion. AB - Layer-by-Layer assembled polyelectrolyte films offer the opportunity to control cell attachment and behavior on solid surfaces. In the present study, multilayer films based on negatively charged biopolymers (pectin, dextran sulfate, carboxymethylcellulose) and positively charged polysaccharide chitosan or synthetic polyelectrolyte polyethyleneimine has been prepared and evaluated. Physico-chemical properties of the formed multilayer films, including their growth, morphology, wettability, stability, and mechanical properties, have been studied. We demonstrated that chitosan-containing films are characterized by the linear growth, the defect-free surface, and predominantly viscoelastic properties. When chitosan is substituted for the polyethyleneimine in the multilayer system, the properties of the formed films are significantly altered: the rigidity and surface roughness increases, the film growth acquires the exponential character. The multilayer films were subsequently used for culturing mesenchymal stem cells. It has been determined that stem cells effectively adhered to chitosan-containing films and formed on them the monolayer culture of fibroblast-like cells with high viability. Our results show that cell attachment is a complex process which is not only governed by the surface functionality because one of the key parameter effects on cell adhesion is the stiffness of polyelectrolyte multilayer films. We therefore propose our Layer-by-Layer films for applications in tissue engineering. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 2093-2104, 2018. PMID- 29569392 TI - Factors affecting the dose of methadone among patients receiving methadone maintenance therapy in Taiwan. AB - BACKGROUND: Methadone maintenance treatment (MMT) has been shown to be an effective therapeutic strategy for opioid users. This study aimed to investigate the predictive effect of clinically predominant sleep disturbance (CPSD) on the dose of methadone among opiate users receiving MMT during a follow-up period of 6 years in Taiwan. METHODS: This retrospective study included 1,290 individuals with opioid dependence who visited our MMT clinic for the first time. Generalized estimating equations were used to analyze the effect of CPSD on the daily dose of methadone by controlling for the effects of demographic and MMT characteristics. RESULTS: A total of 469 (36.4%) participants were comorbid with CPSD. After controlling for the effects of demographic and MMT characteristics, the participants comorbid with CPSD had a higher dose of daily methadone than those without CPSD (estimate: 7.03, p < .001). Furthermore, younger age (estimate: 1.22, p < .001), older age at initial MMT (estimate: .44, p < .001), lower educational level (estimate: -.90, p = .003) and lower attendance rates (estimate: -.14, p = .033) are significantly related to higher doses of daily methadone. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Our study provided a naturalistic observation of the cohort for long period, along with a large sample size which could reflect clinical practice in the real world. We reported that a higher daily dose of methadone was significantly associated with CPSD after controlling for the effects of other factors. CPSD should be routinely surveyed among heroin users receiving MMT. (Am J Addict 2018;27:225-230). PMID- 29569393 TI - Wnt and Notch signaling pathways in calcium phosphate-enhanced osteogenic differentiation: A pilot study. AB - Calcium phosphate (CaP) ceramics are being increasingly used to repair critical bone defect for biocompatibility, biosafety, porous structure and osteoinduction. Wnt and Notch signaling pathways are conservative and classic signaling pathways regulating osteogenic differentiation of bone marrow mesenchymal stromal cells (BMSCs). In this study, we evaluated the expression of Wnt, Notch signal pathways and osteogenic related genes of BMSCs with and without Wnt pathway inhibitor DKK1 on CaP ceramics in vitro by real-time RT-PCR. Also, we evaluated new bone formation after implantation of CaP ceramics in vivo. The in vitro culture displayed the expression of Wnt, Notch signaling pathways and osteogenic related genes was increased at first and then declined. After adding DKK1 to the culture, the expression was decreased. The in vivo implantation showed significant bone formation on CaP ceramics. These findings reveal that Wnt and Notch signaling pathways play important roles in the CaP-enhanced osteogenic differentiation but the mechanism of synergistic effect needs to be further explored.

PMID- 29569394 TI - The bean alpha-amylase inhibitor alphaAI-1 in genetically modified chickpea seeds does not harm parasitoid wasps. AB - BACKGROUND: Legumes have been genetically engineered to express alpha-amylase inhibitor 1 (alphaAI-1) from common bean in their seeds. Whereas the genetically modified (GM) seeds are immune to multiple bruchid pest species, the cosmopolitan bruchid Acanthoscelides obtectus is tolerant to alphaAI-1 and their larvae develop normally inside the seeds. Hymenopteran bruchid parasitoids, the most important natural enemies of bruchids, might thus be exposed to alphaAI-1 when attacking A. obtectus larvae developing inside GM seeds. Exposure might reduce parasitoid fitness, resulting in a decline in the natural control of A. obtectus, and thus promote the spread of this pest. We investigated the impact of the presence of alphaAI-1 in legume seeds on parasitoid fitness in tritrophic experiments with alphaAI-1 GM or non-GM chickpea seeds, A. obtectus, and three parasitoid species. Additionally, we investigated the exposure of parasitoids to alphaAI-1 using a fourth, highly sensitive parasitoid species. RESULTS: Parasitoid fitness was not affected when A. obtectus was used in GM chickpea seeds as hosts, and this lack of effects was probably attributable to the fact that exposure of the parasitoids to alphaAI-1 was negligible. CONCLUSION: We conclude that the release of GM chickpeas containing alphaAI-1 should not harm this important group of non-target insects. (c) 2018 Society of Chemical Industry.

AB - Generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP) are the rare and severe subtypes of psoriasis, which are often difficult to treat. The aim of this phase 3, open-label study was to evaluate efficacy and safety of guselkumab, a human interleukin-23 monoclonal antibody, in Japanese patients with GPP and EP. Guselkumab 50 mg was administrated to GPP (n = 10) and EP (n = 11) patients at weeks 0, 4 and thereafter every 8 weeks (q8w). Beginning at week 20, patients were escalated to 100 mg q8w if they met the dose escalation criteria. The primary end-point was the proportion of patients achieving treatment success (Clinical Global Impression score of "very much improved", "much improved" or "minimally improved") at week 16. Safety evaluations included assessment of treatment-emergent adverse events (TEAE) through week 52. At week 16, the proportions of GPP and EP patients achieving treatment success were 77.8% (7/9) and 90.9% (10/11), respectively. Furthermore, guselkumab treatment consistently showed improvement in responses of secondary end-points such as Psoriasis Area and Severity Index, Investigator's Global Assessment, Japanese Dermatological Association severity index and improvement in body surface area involvement. Improvements in quality of life, as assessed by the Dermatology Life Quality Index, were also observed through week 52. The most commonly reported TEAE was nasopharyngitis (28.6%, 6/21). Safety findings were consistent with those observed previously in other studies. In conclusion, guselkumab treatment demonstrated efficacy and showed no safety concerns in Japanese patients with GPP and EP through week 52. PMID- 29569398 TI - The association of peri-operative scores, including frailty, with outcomes after unscheduled surgery. AB - Postoperative hospital stay is longer for frail, older patients, who are more likely to experience prolonged postoperative morbidity and reduced long-term survival. We recorded in-hospital mortality, morbidity and length of stay for 164 patients aged at least 65 years after unscheduled surgery. We evaluated pre operative frailty with the 7-point Clinical Frailty Scale: 81 patients were 'not vulnerable' (frailty score 1-3) and 83 were 'vulnerable or frail' (frailty score ? 4), with mean (SD) ages of 74.7 (7.5) years vs. 79.4 (8.3) years, respectively, p < 0.001. Within 30 postoperative days 8/164 (5%) patients died, all with frailty scores ? 4, p = 0.007. Postoperative morbidity was less frequent in patients categorised as 'not vulnerable' on four out of the six days it was measured (days 3, 5, 8, 14, 23, 28). Median (IQR [range]) postoperative stay was 9 (6-18 [2-221]) days for patients with frailty scores 1-3, and 22 (12-33 [2 270]) days for patients with score ? 4, p < 0.001. Four variables independently associated with hospital discharge, hazard ratio (95%CI): E-POSSUM, 0.74 (0.60 0.92), p = 0.007; ASA 2, 0.35 (0.13-0.98), p = 0.046, ASA 3, 0.17 (0.06-0.47), p = 0.001 and ASA 4/5, 0.08 (0.02-0.28), p < 0.001; operative severity 'major +', 0.69 (0.41-1.08), p = 0.10 and the Surgical Outcome Risk Tool, 7.75 (0.81-74.40), p = 0.08. PMID- 29569400 TI - Increased serum levels of high mobility group protein B1 and calprotectin in pre eclampsia. AB - OBJECTIVE: To determine whether women with pre-eclampsia have serum levels of biomarkers indicative of an elevated systemic inflammatory response. METHOD: The present cross-sectional study was conducted among pregnant women either with pre eclampsia or without pre-eclampsia who were recruited at a single Chinese hospital between August 1, 2016, and April 30, 2017. Eligible women had no history of acute or chronic inflammation. Serum concentrations of high mobility group protein B1 (HMG-1), calprotectin, and Toll-like receptor 4 (TLR4) were measured and compared. RESULTS: There were 55 patients included (25 with pre eclampsia and 30 without). The mean serum concentration of calprotectin was 2656.76 +/- 1724.56 MUg/L in the pre-eclampsia group versus 1877.33 +/- 905.69 MUg/L in the control group (P=0.036). Among patients with pre-eclampsia, elevated calprotectin levels were positively associated with the duration of hypertension in pregnancy (P=0.031) and were negatively associated with pregnancy duration at delivery (P=0.035). The mean serum concentration of HMG-1 was 72.48 +/- 27.57 MUg/L in the pre-eclampsia group versus 57.57 +/- 20.07 MUg/L in the control group (P=0.017). The mean serum concentration of TLR4 was 22.83 +/- 8.46 MUg/L in the pre-eclampsia group versus 18.83 +/- 6.79 MUg/L in the control group (P=0.057). CONCLUSION: Elevated levels of HMG-1 and calprotectin could reflect an excessive systemic inflammatory response in pre-eclampsia. PMID- 29569399 TI - Identification of clinically relevant phenotypes in patients with Ebstein anomaly. AB - BACKGROUND: Ebstein anomaly (EA) is a heterogeneous congenital heart defect (CHD), frequently accompanied by diverse cardiac and extracardiac comorbidities, resulting in a wide range of clinical outcomes. HYPOTHESIS: Phenotypic characterization of EA patients has the potential to identify variables that influence prognosis and subgroups with distinct contributing factors. METHODS: A comprehensive cross-sectional phenotypic characterization of 147 EA patients from one of the main referral institutions for CHD in Colombia was carried out. The most prevalent comorbidities and distinct subgroups within the patient cohort were identified through cluster analysis. RESULTS: The most prevalent cardiac comorbidities identified were atrial septal defect (61%), Wolff-Parkinson-White syndrome (WPW; 27%), and right ventricular outflow tract obstruction (25%). Cluster analysis showed that patients can be classified into 2 distinct subgroups with defined phenotypes that determine disease severity and survival. Patients in cluster 1 represented a particularly homogeneous subgroup with a milder spectrum of disease, including only patients with WPW and/or supraventricular tachycardia (SVT). Cluster 2 included patients with more diverse cardiovascular comorbidities. CONCLUSIONS: This study represents one of the largest phenotypic characterizations of EA patients reported. The data show that EA is a heterogeneous disease, very frequently associated with cardiovascular and noncardiovascular comorbidities. Patients with WPW and SVT represent a homogeneous subgroup that presents with a less severe spectrum of disease and better survival when adequately managed. This should be considered when searching for genetic causes of EA and in the clinical setting. PMID- 29569401 TI - Sedative and cardiorespiratory effects of low doses of xylazine with and without acepromazine in Nordestino donkeys. AB - BACKGROUND: Information on appropriate protocols for sedation of Nordestino donkeys is scarce. OBJECTIVES: To evaluate the sedative and cardiorespiratory effects of low doses of intravenous (i.v.) xylazine with and without acepromazine in 'Nordestino' donkeys. STUDY DESIGN: Seven healthy female Nordestino donkeys (150 +/- 18 kg) were included in this blinded, randomised, crossover experiment. METHODS: Four treatments were administered, consisting of two i.v. injections, at baseline (T0, 1st injection) and 15 min later (T15, 2nd injection). Treatments included acepromazine 0.05 mg/kg bwt + saline (AS), saline + xylazine 0.5 mg/kg bwt (SX0.5), acepromazine + xylazine 0.25 mg/kg bwt (AX0.25) or acepromazine + xylazine 0.5 mg/kg bwt (AX0.5). Sedative and cardiorespiratory parameters were evaluated before T0 and 15, 20, 30, 45, 60, 75 and 90 min after treatment. Degree [height of head above ground (HHAG)] and quality of sedation [ataxia, responses to stimuli and visual analogue scale (VAS) scoring] and respiratory rate were evaluated by the main investigator in situ, and heart rate was measured by an assistant investigator. Three experienced evaluators assessed videos for ataxia and responses to stimuli. Normal data were analysed by repeated measures ANOVA, and non-normal by Kruskal-Wallis (P<0.05). RESULTS: HHAG was lower than baseline for 15 min after xylazine administration in AX0.25 and for 30 min in SX0.5 and AX0.5 groups. All treatments with xylazine increased VAS and ataxia scores in situ for 15 min after xylazine administration, with no differences between groups. Ataxia scores in situ were higher in SX0.5 and AX0.5 groups than AS for 15 and 30 min after xylazine administration, respectively. MAIN LIMITATIONS: Absence of a negative control group (saline-saline). CONCLUSION: Acepromazine added to xylazine at 0.25 mg/kg bwt produced briefer and milder sedation than xylazine at 0.5 mg/kg bwt. PMID- 29569403 TI - Generalizability of the findings from a randomized controlled trial of a web based substance use disorder intervention. AB - BACKGROUND AND OBJECTIVES: There is growing concern regarding the generalizability of findings from randomized controlled trials (RCTs) of interventions for substance use disorders (SUDs). This study used a selection model approach to assess and improve the generalizability of an evaluation for a web-based SUD intervention by making the trial sample resemble the target population. METHODS: The sample of the web-based SUD intervention (Therapeutic Education System vs. Treatment-as-usual; n = 507) was compared with the target population of SUD treatment-seeking individuals from the Treatment Episodes Data Set-Admissions (TEDS-A). Using weights based on the probabilities of RCT participation, we computed weighted treatment effects on retention and abstinence. RESULTS: Substantial differences between the RCT sample and the target population was demonstrated in significant difference in the mean propensity scores (1.62 standard deviations at p < .001). The population effect on abstinence (12 weeks and 6 months) was statistically insignificant after weighting the data with the generalizability weight. DISCUSSIONS AND CONCLUSIONS: Generalizability of the findings from the RCT could be limited when the RCT sample does not well represent the target population. SCIENTIFIC SIGNIFICANCE: Application of generalizability weights can be a potentially useful tool to improve generalizability of RCT findings. (Am J Addict 2018;27:231-237). PMID- 29569402 TI - Use of neutrophil-lymphocyte ratio for risk stratification and relationship with time in therapeutic range in patients with nonvalvular atrial fibrillation: A pilot study. AB - BACKGROUND: Atrial fibrillation is one of the most common abnormal heart rhythms. Neutrophil-lymphocyte ratio (NLR) has emerged as a potential marker for the level of inflammation in cardiac disorders. HYPOTHESIS: NLR might be associated with thrombosis and bleeding risk scores and might predict cardioembolic risk in nonvalvular atrial fibrillation (NVAF) patients within the therapeutic international normalized ratio (INR). METHODS: We enrolled 272 patients taking warfarin for NVAF and classified them into 2 groups: Group A consisted of patients (n = 132) whose time in therapeutic range (TTR) was >=65%, and Group B comprised patients (n = 139) whose TTR was <65%. RESULTS: NLR values were higher in group B than in group A (P < 0.0001). Patients classified as high risk according to CHA2 DS2 -VASc score had significantly higher NLR levels (P = 0.002) than those classified as low and intermediate risk. Furthermore, NLR levels were significantly correlated with CHA2 DS2 -VASc and HAS-BLED scores (P < 0.001 and P < 0.0001, respectively). NLR predicted patients within therapeutic INR range (TTR >=65%) with sensitivity of 81% and specificity of 71% in a receiver operator characteristic curve analysis, using a cutoff value of 2.17. Area under the curve for NLR was 0.81 (P < 0.0001). CONCLUSIONS: To our knowledge, this is the first study showing correlation of NLR with both CHA2 DS2 -VASc and HAS-BLED risk scores. NLR might represent a useful marker to identify patients with high risks of stroke and bleeding and may have predictive value in identifying patients within the therapeutic INR range. PMID- 29569404 TI - Clinical predictors of Alzheimer's disease progression. AB - AIM: Rates of disease progression differ among patients with Alzheimer's disease (AD), but prognostic predictions remain a challenge. We carried out a clinic based retrospective study to investigate the clinical factors for AD progression. METHODS: The 748 AD patients, who attended our hospital for >1 year and were given the Mini-Mental State Examination (MMSE) at least three times, were divided into three groups according to the annual change rate of MMSE score (G): Aggravater group (G < -2), Stabler group (-2 <= G <= 2) and Improver group (2 < G). We compared the three groups on cognitive, affective and activities of daily living functions, response to medication, clinical fluctuations, serum levels of metabolic factors, and neuroimaging data. RESULTS: We found no significant differences in age, sex, educational attainment or body mass index across the groups. The Aggravater group showed better baseline MMSE (P < 0.01) and Abe's behavioral and psychological symptoms of dementia (P < 0.01) scores than the Improver group, but its MMSE improvement after drug treatment was the worst among the three groups (P < 0.01 vs Stabler/Improver). Fluctuations in MMSE (P < 0.01), apathy scale (P < 0.05) and activities of daily living (P < 0.01) scores were smaller in the Improver group than in the Aggravater or Stabler groups. Serum docosahexaenoic acid levels tended to be lower (trend P < 0.05) and voxel-based specific regional analysis system for Alzheimer's disease Z-scores tended to be higher (trend P < 0.05) in the Improver group than in the Stabler or Aggravater groups. CONCLUSIONS: Initial responses to medication, fluctuations in cognitive, affective and activities of daily living functions, serum docosahexaenoic acid levels, and medial temporal atrophy are clinical factors related to AD prognosis.

PMID- 29569405 TI - Digoxin use and lower risk of 30-day all-cause readmission in older patients with heart failure and reduced ejection fraction receiving beta-blockers. AB - BACKGROUND: Digoxin use has been associated with a lower risk of 30-day all-cause admission and readmission in patients with heart failure and reduced ejection fraction (HFrEF). HYPOTHESIS: Digoxin use will be associated with improved outcomes in patients with HFrEF receiving beta-blockers. METHODS: Of the 3076 hospitalized Medicare beneficiaries with HFrEF (EF <45%), 1046 received a discharge prescription for beta-blockers, of which 634 were not on digoxin. Of the 634, 204 received a new discharge prescription for digoxin. Propensity scores for digoxin use, estimated for each of the 634 patients, were used to assemble a matched cohort of 167 pairs of patients receiving and not receiving digoxin, balanced on 30 baseline characteristics. Matched patients (n = 334) had a mean age of 74 years and were 46% female and 30% African American. RESULTS: 30-day all cause readmission occurred in 15% and 27% of those receiving and not receiving digoxin, respectively (hazard ratio [HR]: 0.51, 95% confidence interval [CI]: 0.31-0.83, P = 0.007). This beneficial association persisted during 4 years of follow-up (HR: 0.72, 95% CI: 0.57-0.92, P = 0.008). Digoxin use was also associated with a lower risk of the combined endpoint of all-cause readmission or all-cause mortality at 30 days (HR: 0.54, 95% CI: 0.34-0.86, P = 0.009) and at 4 years (HR: 0.76, 95% CI: 0.61-0.96, P = 0.020). CONCLUSIONS: In hospitalized patients with HFrEF receiving beta-blockers, digoxin use was associated with a lower risk of 30-day all-cause readmission but not mortality, which persisted during longer follow-up. PMID- 29569406 TI - An ecological perspective on managing weeds during the great selection for herbicide resistance. AB - More than 70 years after modern agriculture declared a 'war on weeds', they continue to thrive and suppress crop yields. Viewing weeds as an enemy that can be defeated if only a powerful enough technology can be deployed is a losing proposition. The latest evidence for the inadequacy of this approach, rampant evolution of multiple herbicide-resistant weed genotypes and dwindling options for chemical control in many production systems, should be seen as an urgent message to all those concerned with the science and practice of weed management: we need another way of thinking about the weed resistance issue. Fortunately, the theoretical and practical foundation of this alternative approach, ecological weed management, has been in development for decades. Here, we use Barry Commoner's laws of ecology as a conceptual frame for a review of some of the fundamental concepts of ecological weed management. (c) 2018 Society of Chemical Industry.

AB - The recognition that antidepressants are effective in panic and anxiety disorders had led to the evaluation of drugs selective for serotonin uptake in an attempt to dissect the neurotransmitters responsible for panic disorder. Fluvoxamine is the best studied of the selective serotonin reuptake inhibitors (SSRIs) and recent double-blind studies have confirmed earlier findings showing a reduced number and duration of panic attacks. In addition, fluvoxamine attenuates the 'accessory symptoms' of panic disorder such as depression and anxiety. Fluoxetine has only been evaluated in open trials, although these results are generally positive. Paroxetine has shown similar efficacy to clomipramine in a large, controlled study, although the other SSRIs have seldom been investigated. Fluvoxamine lacks the activating properties possessed by some SSRIs and this also makes it a useful candidate for the treatment of anxious depression. The efficacy of fluvoxamine in obsessive-compulsive disorder has been established in several double-blind, placebo-controlled trials. In clinical terms, fluvoxamine is approximately as effective as clomipramine, but with a decidedly better adverse event profile. Fluoxetine has also proved effective in obsessive-compulsive disorder, although a recent meta-analysis suggests that fluvoxamine may be somewhat more effective. The other SSRIs have not been sufficiently well studied to justify conclusive statements. PMID- 29569410 TI - Do SSRIs differ in their antidepressant efficacy. AB - Selective serotonin reuptake inhibitors (SSRIs) have been extensively studied worldwide and show at least equivalent efficacy to the tricyclic antidepressants (TCAs). Some of the SSRIs have demonstrated superior efficacy to TCAs in a number of subgroups including patients with severe depression, suicidal thoughts or depression associated with anxiety. There is currently a lack of direct comparative data between the different SSRIs, although the few studies which are available indicate overall equal efficacy. However, the pharmacodynamic and pharmacokinetic characteristics may result in different side-effects which might, in turn, lead to a characteristic pattern of use. PMID- 29569407 TI - Neurotensin and neurotensin receptor 1 mRNA expression in song-control regions changes during development in male zebra finches. AB - Learned vocalizations are important for communication in some vertebrate taxa. The neural circuitry for the learning and production of vocalizations is well known in songbirds, many of which learn songs initially during a critical period early in life. Dopamine is essential for motor learning, including song learning, and dopamine-related measures change throughout development in song-control regions such as HVC, the lateral magnocellular nucleus of the anterior nidopallium (LMAN), Area X, and the robust nucleus of the arcopallium (RA). In mammals, the neuropeptide neurotensin strongly interacts with dopamine signaling. This study investigated a potential role for the neurotensin system in song learning by examining how neurotensin (Nts) and neurotensin receptor 1 (Ntsr1) expression change throughout development. Nts and Ntsr1 mRNA expression was analyzed in song-control regions of male zebra finches in four stages of the song learning process: pre-subsong (25 days posthatch; dph), subsong (45 dph), plastic song (60 dph), and crystallized song (130 dph). Nts expression in LMAN during the subsong stage was lower compared to other time points. Ntsr1 expression was highest in HVC, Area X, and RA during the pre-subsong stage. Opposite and complementary expression patterns for the two genes in song nuclei and across the whole brain suggest distinct roles for regions that produce and receive Nts. The expression changes at crucial time points for song development are similar to changes observed in dopamine studies and suggest Nts may be involved in the process of vocal learning.

AB - Selective serotonin reuptake inhibitors (SSRIs) are widely accepted as the best available treatment for most forms of depression. However, to date, there has been little attempt to differentiate between the members of this class of drugs. Since, unlike the tricyclic antidepressants, the SSRIs have very different chemical structures, it is not unexpected that they may have different pharmacological properties. These differences in pharmacology may, in turn, be expressed in varying pharmacokinetic, efficacy, safety and tolerability profiles which mean that the SSRIs may be a less homogeneous class of compounds than is generally assumed. This review analyses the differences between the SSRIs with the intention of helping the practising clinician to select the most appropriate drug for a particular patient. PMID- 29569412 TI - Comparative behavioural toxicity of the selective serotonin reuptake inhibitors. AB - The psychopharmacological profiles of several selective serotonin reuptake inhibitors (SSRIs) were compared and their behavioural toxicity contrasted both to placebo and the tricyclic antidepressants dothiepin and amitriptyline. On measures of central nervous system arousal (critical flicker fusion), psychomotor speed (choice reaction time), skilled performance (compensatory tracking) and subjective ratings of sedation (line analogue rating scales), the tricyclic compounds clearly impaired performance and led to higher ratings of sedation. While the SSRIs were generally clear of these gross effects, there were quantifiable differences between the compounds, seen mainly as an increase in central nervous system arousal. It remains to be established whether these minor differences have any clinical relevance. PMID- 29569413 TI - Differential costs of treatment of depression with SSRIs. AB - Although the field of economic analysis of mental health care is still in development, several issues are now well established. For example, it is generally accepted that the treatment costs for depression are significant, with estimates for the US ranging up to US$43.7 billion. This includes only US$12.4 billion for the costs of treating the patients with depression; the remaining costs are from lost working days, lost income due to suicides, and lost productivity. The high risk of recurrence and chronicity also leads to high direct health care costs. In particular, the frequent and long hospitalizations required for severe depression have an enormous impact in economic terms. The other main costs are related to drug and psychotherapy, and the treatment of side effects, which are particularly pronounced with the tricyclic antidepressants. Preliminary analyses indicate that the differential tolerability of the current selective serotonin reuptake inhibitors (SSRIs) can also give rise to differences in total costs of treatment. Thus, it can be hypothesized that the relatively favourable side-effect profile of the SSRI fluvoxamine may have positive economic consequences, especially as it is one of the lower priced drugs in this class. Further research based on primary data is needed to substantiate these benefits. PMID- 29569414 TI - SSRI differentiation: Pharmacology and pharmacokinetics. AB - Although the acute pharmacology properties of antidepressants is predominantly due to their presynaptic action, their therapeutic activity is believed to derive from adaptive post-synaptic changes in monoaminergic neurones. The selective serotonin reuptake inhibitors (SSRIs) exhibit differences in potency at inhibiting serotonin reuptake, although the differences do not correlate with clinical posology. There are also differences in their effects on neurotransmitter receptors; paroxetine has a slight affinity for muscarinic cholinergic receptors whilst citalopram has a slight affinity for histamine-H1 receptors. These properties may be related to clinical adverse effects. The pharmacokinetic profiles of the SSRIs show many differences. Whilst fluvoxamine, paroxetine and citalopram are metabolized to inactive products, fluoxetine is metabolized to norfluoxetine which is pharmacologically active and, like its parent compound, has a long half-life. Fluvoxamine is less protein-bound than the other SSRIs and sertraline is only well absorbed when taken with food. Differences are also apparent in the suitability of individual SSRIs in special patient groups. There has been considerable speculation over the inhibition of cytochrome P450 isoenzymes which are responsible for the metabolism of SSRIs and other drugs. In clinical practice, the differences between the SSRIs in this respect are probably of limited importance. However, it is worthwhile that clinicians be made aware of possible interactions between drugs that act as inhibitors or substrates of the hepatic cytochrome P450 system. PMID- 29569415 TI - Comparative safety and tolerability of selective serotonin reuptake inhibitors. AB - The selective serotonin reuptake inhibitors (SSRIs) have the best established tolerance and safety profile of the available antidepressants. Evidence for this conclusion comes from controlled clinical trials, post-marketing surveillance, prescription audits and case reports. Comparative studies are sparse within the class of SSRIs, and methodological differences between studies are problematic, yet certain differences emerge in tolerability when comparing placebo-adjusted incidence rates for the most common adverse events. Fluoxetine commonly produces nervousness, anxiety, insomnia and headache. Sexual dysfunction is more common with sertraline. Dry mouth can occur from paroxetine, and gastrointestinal effects (cramps, diarrhoea) from sertraline. The incidence of nausea appears to be no greater for any particular drug, especially after several weeks of treatment. Hyponatraemia and extrapyramidal side effects are rare events reported with all SSRIs. General guidelines are given for choosing an initial SSRI according to adverse effect profile; however, inter-subject variability exists in the expression of adverse effects, as well as intra-subject variability during treatment, suggesting the development of pharmacodynamic tolerance. Thus, rational selection of an SSRI on the basis of comparative tolerability is possible, but largely empirical without further scientific evidence from clinical trials specifically designed to differentiate drugs according to their adverse effect profile. PMID- 29569416 TI - History of burning mouth syndrome (1800-1950): A review. AB - This medical history historic literature review aims at understanding the evolution of the medical existence of burning mouth syndrome (BMS) over times. Three historic research tools were used (Medic@, IndexCat, Gallica) with several keywords, exploring the years 1800-1950. One hundred and fifty documents were obtained dating from 1803 to 1937, including 55 reviews, 44 original articles, 40 quotations, and 11 medical dictionaries. A total of 199 cases of BMS were reported which allowed for a narrative review of the early history of BMS (1800 1950). This review spans from the description of the first clinical cases by several authors in Europe to the creation of the syndrome by the French Academy of Medicine, its intellectual sponsorship by the emerging discipline of neuropsychiatry, to its subsequent evolution until the conceptual shift of the American authors. A better knowledge of the evolution of the nosology of BMS throughout history should bring a better understanding of current approaches for treating such an affection. PMID- 29569417 TI - Dermoscopy features of atypical fibroxanthoma: A multicenter study of the International Dermoscopy Society. AB - BACKGROUND/OBJECTIVES: Little is known about the dermoscopic features of atypical fibroxanthoma. METHODS: This was a case-control study. Atypical fibroxanthoma lesions were compared with a control group with non-melanoma skin cancer. RESULTS: Altogether 40 atypical fibroxanthoma were collected. Most developed in men (93%), appearing mainly as nodular (63%), amelanotic (93%) and ulcerated (78%) lesions. Most lesions were located on the scalp (55%) and the ears (13%). Dermoscopically, most atypical fibroxanthoma displayed red (83%) and white (70%) structureless areas and irregular linear vessels (43%). A series of features achieved statistical significance when comparing atypical fibroxanthoma with non melanoma skin cancer. The presence of red and white structureless areas and white lines, and the absence of yellowish-white opaque scales, hairpin vessels and arborising vessels were predictive of atypical fibroxanthoma in univariate analysis. However, when squamous cell carcinoma was excluded from the analysis, none of the criteria achieved statistical significance. When basal cell carcinoma was excluded, three variables achieved statistical significance in predicting atypical fibroxanthoma: red, structureless areas, the absence of opaque yellowish white scales and absence of white circles. CONCLUSIONS: Atypical fibroxanthomas seem to be barely distinguishable from basal cell carcinoma dermoscopically, but they are more easily distinguishable from a well to moderately differentiated squamous cell carcinoma. A histopathological examination is needed for the final diagnosis. PMID- 29569418 TI - Monitoring of pH and temperature of neuropathic diabetic and nondiabetic foot ulcers for 12 weeks: An observational study. AB - Wound bed assessment is largely reliant on subjective interpretation without recourse to objective tools or biomarkers. The identification of a point of care, reliable biomarker would enhance assessment and ultimately clinical decision making. Two potentially emerging wound biomarkers exist: surface pH and surface temperature. To date, knowledge of their use has been predominantly in wound prevention, in vitro studies and single time measurements. Our objective was to determine surface pH, size, and surface temperature in noninfected, neuropathic foot ulcers at baseline and at 12 weeks. 50 patients (68% [n = 34] had diabetes) participated. Mean baseline pH of wounds was 6.95 (SD 1.01); temperature 30.91 degrees C (SD 3.00); and size 0.82 cm2 (SD 0.61). After 12 weeks, 26% (n = 13) were lost to follow-up, 50% (n = 25) had healed. Of the remaining patients, mean pH was 6.72 (SD 0.54); temperature 30.88 degrees C (SD 2.97), and size 0.13 cm2 (SD 0.13). We have provided baseline values for pH and temperature of noninfected, neuropathic diabetic, and nondiabetic foot ulceration. Further studies in a larger cohort are warranted to determine if temperature and or pH are indicative of a healing or nonhealing state. PMID- 29569419 TI - Patients with perianal Crohn's fistulas experience delays in accessing anti-TNF therapy due to slow recognition, diagnosis and integration of specialist services: lessons learned from three referral centres. AB - AIM: Crohn's anal fistula should be managed by a multidisciplinary team. There is no clearly defined 'patient pathway' from presentation to treatment. The aim of this study was to describe the patient route from presentation with symptomatic Crohn's anal fistula to starting anti-tumour necrosis factor (anti-TNF) therapy. METHOD: Case note review was undertaken at three hospitals with established inflammatory bowel disease services. Patients with Crohn's anal fistula presenting between 2010 and 2015 were identified through clinical coding and local databases. Baseline demographics were captured. Patient records were interrogated to identify route of access, and clinical contacts during the patient pathway. RESULTS: Seventy-nine patients were included in the study, of whom 54 (68%) had an established diagnosis of Crohn's disease (CD). Median time from presentation to anti-TNF therapy was 204 days (174 vs 365 days for existing and new diagnosis of CD, respectively; P = 0.019). The mean number of surgical outpatient attendances, operations and MRI scans per patient was 1.03, 1.71 and 1.03, respectively. Patients attended a mean of 1.49 medical clinics. Seton insertion was the most common procedure, accounting for 48.6% of all operations. Where care episodes ('clinical events per 30 days') were infrequent this correlated with prolongation of the pathway (r = -0.87; P < 0.01). CONCLUSION: This study highlights two key challenges in the treatment pathway: (i) delays in diagnosis of underlying CD in patients with anal fistula and (ii) the pathway to anti-TNF therapy is long, suggesting issues with service design and delivery. These should be addressed to improve patient experience and outcome. PMID- 29569420 TI - Impact of postgraduate education on advanced practice nurse activity - a national survey. AB - BACKGROUND: There is a wealth of international evidence concerning the contribution post-registration master's level education makes to advancing the discipline of nursing. There are approximately 277 nurse practitioners registered in NZ, but they account for only a small portion of nurses who have undertaken master's level education. The additional contribution these nurses make to the work environment through advanced practice activities has not, hitherto, been documented. OBJECTIVES: To report the extent of advanced practice nurse activity associated with various levels of nursing education in a sample of nurses working in clinical practice in New Zealand. METHOD: A replication of recent Australian research was done via a national cross-sectional survey of 3255 registered nurses and nurse practitioners in New Zealand using an online questionnaire to collect responses to the amended Advanced Practice Delineation survey tool. In addition, demographic data were collected including position titles and levels of postgraduate education. RESULTS: A positive association was found between postgraduate education at any level and more time spent in advanced practice activities. Independent of level of postgraduate education, the role a nurse holds also effects the extent of involvement in advanced practice activities. CONCLUSIONS: There is an additional contribution made to the work environment by nurses with master's level education which occurs even when they are not employed in an advanced practice role. IMPLICATIONS FOR NURSING POLICY: These findings are of significance to workforce policy and planning across the globe as countries work to sustain health services by increasing nursing capacity effectively within available resources. PMID- 29569421 TI - Periodic microstructures on bioactive glass surfaces enhance osteogenic differentiation of human mesenchymal stromal cells and promote osteoclastogenesis in vitro. AB - Bioactive glasses (BG) are known for their ability to bond to hard and soft tissues. We hypothesized that the stimulation of bone remodeling, including cellular bone forming and bone resorbing processes, can be increased by applying periodic microstructures on the glass surfaces in vitro. To test our hypothesis, two different BG (45S5 and 13-93) were microstructured in a groove-and-ridge pattern of different sizes by a novel casting process and tested in cell culture experiments using human mesenchymal stromal cells (hMSCs) and RAW 264.7 cells. The microstructures induced contact guidance of hMSCs and increased osteogenic marker gene expression of the stem cells, compared to non-structured glass surfaces as verified by ELISA and quantitative real-time PCR (qPCR) analyses. Furthermore, the structures stimulated the differentiation of RAW cells to osteoclast-like cells confirmed by TRAP gene expression and their resorption activity causing visible resorption lacunae. Our results demonstrate that periodically microstructured BG (especially 45S5) might improve the osteogenic differentiation of hMSCs and influence the activity of material resorbing cells in vitro. Hence, microstructuring of BG could enhance the remodeling process of bone substitutes critical for the formation of new bone tissue in vivo and thus be used to trigger bone remodeling kinetics in vivo.

AB - BACKGROUND: The aim of this study was to determine the effects of obesity on myocardial mechanics and ventriculo-arterial coupling (V-A) in children. METHODS: Strain parameters, stroke volume, arterial elastance, left ventricular (LV) elastance and V-A were compared after adjusting for age and hypertension and after multivariate sub-group analysis between patients with and without obesity. RESULTS: Among 123 retrospectively enrolled subjects, 6-21 years age, 79.7% males, 52% were obese. Median (range) Body Mass Index Z score was +2.35 (1.67 4.43) for obese and +0.68 (-2.48-1.63) for non-obese. Subjects with obesity had higher LV mass indexed2.7 (LVMI2.7 ) compared with non-obese (P < 0.001). Lower global longitudinal strain (GLS) (P = 0.012), global circumferential strain (GCS) (P = 0.004), average longitudinal strain rate (P = 0.002) and average circumferential strain rate (P < 0.001) were seen in subjects with obesity; no difference was noted in arterial elastance, LV end systolic elastance and V-A. Increased LVMI2.7 , decreased GLS, GCS, average longitudinal strain rate, average circumferential strain rate and maintained V-A were noted in the multivariate analysis between subgroups. CONCLUSIONS: Obesity causes alterations in myocardial mechanics with preserved V-A in children. These findings may aid intervention in preventing the long-term cadiovascular effects of obesity. PMID- 29569423 TI - The Roles of Social Support and Health Literacy in Self-Management Among Patients With Chronic Kidney Disease. AB - AIMS: To investigate the relationships among social support, health literacy, and self-management, and the factors influencing self-management of chronic kidney disease (CKD). DESIGN: Cross-sectional study. METHODS: A random sample of 410 patients was recruited from nephrology clinics. Data were collected using structured questionnaires and chart reviews from January 2013 to February 2014. Hierarchical regression analysis was used to determine the predictive factors of self-management behaviors and ?R2 to determine each variable's explanatory power. FINDINGS: Health literacy and social support were positively correlated with self management behaviors. Furthermore, social support, health literacy, and marital status were significant predictors of self-management behaviors. Social support had a relatively greater explanatory power for self-management behaviors than did health literacy. Particularly, healthcare provider support had the greatest influence on patients' self-management behaviors. CONCLUSIONS: Health literacy and social support play independent positive roles in self-management behaviors of patients with CKD, with social support having a particularly dominant role. Further research using a systems approach to improving self-management behaviors is necessary to clarify the role of social support. CLINICAL RELEVANCE: Health literacy and social support are independently and positively related to self management. Social support, which is a system-level factor, is a relatively stronger and crucial predictor than is health literacy. Nurses have to refine self-management programs to focus on families and adopt a systems approach to help CKD patients improve their self-management behaviors. PMID- 29569424 TI - Left atrial volume in patients with HER2-positive breast cancer: One step further to predict trastuzumab-related cardiotoxicity. AB - BACKGROUND: Trastuzumab (TZ) therapy requires careful monitoring of left ventricular (LV) ejection fraction (LVEF) because it can be potentially cardiotoxic. However, LVEF is an imperfect parameter and there is a need to find other variables to predict cardiac dysfunction early. Left atrium (LA) enlargement has proven to be a powerful predictor of adverse outcomes in several disease entities. HYPOTHESIS: Baseline LA volume enlargement might predict TZ related LV dysfunction. METHODS: HER2-positive breast cancer patients receiving TZ and undergoing transthoracic echocardiography at baseline and at follow-up every 3 months were retrospectively recruited. One-hundred sixty-two patients formed the study population. RESULTS: Baseline LAVI was dilated in 14 patients (8.6%). Mean follow-up was 14 +/- 4 months. Cardiotoxicity occurred in 24 patients (14.8%). LAVI was an independent predictor of TZ-induced LV dysfunction in a clinical model, after adjustment for age and hypertension (odds ratio per 5 mL/m2 LAVI increase: 1.34, 95% confidence interval: 1.03-1.82, P = 0.03); and in a hemodynamic model, including ventricular sizes and systolic blood pressure level (odds ratio per 5-mL/m2 LAVI increase: 1.34, 95% confidence interval: 1.01 1.81, P = 0.04). The predicted probability of developing cardiotoxicity increased progressively, in parallel with LAVI values. CONCLUSIONS: Baseline LA dilatation emerges as a condition associated with the development of cardiotoxicity in HER2 positive breast cancer patients treated with TZ. PMID- 29569425 TI - Comparative analysis of nanobody sequence and structure data. AB - Nanobodies are a class of antigen-binding protein derived from camelids that achieve comparable binding affinities and specificities to classical antibodies, despite comprising only a single 15 kDa variable domain. Their reduced size makes them an exciting target molecule with which we can explore the molecular code that underpins binding specificity-how is such high specificity achieved? Here, we use a novel dataset of 90 nonredundant, protein-binding nanobodies with antigen-bound crystal structures to address this question. To provide a baseline for comparison we construct an analogous set of classical antibodies, allowing us to probe how nanobodies achieve high specificity binding with a dramatically reduced sequence space. Our analysis reveals that nanobodies do not diversify their framework region to compensate for the loss of the VL domain. In addition to the previously reported increase in H3 loop length, we find that nanobodies create diversity by drawing their paratope regions from a significantly larger set of aligned sequence positions, and by exhibiting greater structural variation in their H1 and H2 loops. PMID- 29569426 TI - Changes in thiol/disulfide homeostasis in juvenile idiopathic arthritis. AB - BACKGROUND: The pathogenesis of juvenile idiopathic arthritis (JIA) remains unknown, but imbalance between the oxidant and antioxidant defense systems may play a role. Measuring thiols in plasma provides an indirect indication of antioxidative defense. The aim of the present study was to investigate the association between JIA and dynamic thiol/disulfide homeostatic status. METHODS: This case-control study involved 34 JIA patients and 30 age- and gender-matched healthy controls. The patients were divided into subgroups according to Simplified Disease Activity Index (SDAI) score: active, SDAI > 3.3; remission, SDAI <= 3.3. RESULTS: Native thiol and total thiol were significantly lower in the JIA group than in the control group (P = 0.001). There was no significant difference in the disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol ratios between the JIA and control groups (P > 0.05). Based on SDAI score, 22 JIA patients were in the remission subgroup, and 12 JIA patients were in the active subgroup. Native thiol and total thiol were significantly lower in the active JIA subgroup than in the remission subgroup (P = 0.001), but there were no significant differences in the other parameters. There was no significant difference in thiol and disulfide levels between systemic-onset JIA and other JIA (P > 0.05). CONCLUSIONS: Plasma thiol is lower in JIA patients, especially during periods of active disease, than in healthy controls, indicating that low thiol might be an important factor in the etiology of JIA and that antioxidant systems are negatively affected by inflammatory diseases, especially during periods of active disease. PMID- 29569427 TI - Sodium-glucose co-transporter-2 inhibitors and the risk of ketoacidosis in patients with type 2 diabetes mellitus: A nationwide population-based cohort study. AB - AIMS: To estimate the risk of diabetic ketoacidosis (DKA) associated with sodium glucose co-transporter-2 (SGLT2) inhibitor treatment compared with the risk associated with dipeptidyl-peptidase-4 (DPP-4) inhibitor treatment. METHODS: A nationwide population-based cohort study using claims data from the Korean Health Insurance Review and Assessment Service from January 1, 2013 to June 30, 2017 was performed. A total of 56 325 patients who were started on SGLT2 inhibitors were included in this study and were matched with same number of patients who were started on DPP-4 inhibitors using propensity score matching. Kaplan-Meier curves and Cox proportional hazards regression analyses were used to estimate the risk of hospitalization for DKA. RESULTS: The risk of hospitalization for DKA was not increased in SGLT2 inhibitor users vs DPP-4 inhibitor users (hazard ratio [HR] 0.956, 95% confidence interval [CI] 0.581-1.572; P = .996). The incidence rate of hospitalization for DKA during the first 30 days after initiation of the SGLT2 inhibitor was 2.501 cases per 1000 person-years, which was higher than the rate during 3 years (0.614 cases per 1000 person-years). SGLT2 inhibitor use was associated with a higher HR in patients with diabetic microvascular complications (HR 2.044, 95% CI 0.900-4.640; P = .088) and in patients taking diuretics (HR 3.648, 95% CI 0.720-18.480; P = .118), although these associations were not statistically significant. CONCLUSION: We found that SGLT2 inhibitor treatment did not increase the risk of DKA compared with DPP-4 inhibitor treatment. Our findings suggest that patients prescribed diuretics or those with microvascular complications may have a greater tendency to be hospitalized for DKA. PMID- 29569428 TI - Novel assay demonstrates that coronary artery disease patients have heightened procoagulant platelet response. AB - : Essentials Procoagulant platelets can be detected using GSAO in human whole blood. Stable coronary artery disease is associated with a heightened procoagulant platelet response. Agonist-induced procoagulant platelet response is not inhibited by aspirin alone. Collagen plus thrombin induced procoagulant platelet response is partially resistant to clopidogrel. SUMMARY: Background Procoagulant platelets are a subset of highly activated platelets with a critical role in thrombin generation. Evaluation of their clinical utility in thrombotic disorders, such as coronary artery disease (CAD), has been thwarted by the lack of a sensitive and specific whole blood assay. Objectives We developed a novel assay, utilizing the cell death marker, GSAO [(4-(N-(S glutathionylacetyl)amino)phenylarsonous acid], and the platelet activation marker, P-selectin, to identify procoagulant platelets in whole blood by flow cytometry. Patients/Methods Using this assay, we characterized the procoagulant platelet population in healthy controls and a cohort of patients undergoing elective coronary angiography. Results In patients with CAD, compared with patients without CAD, there was a heightened procoagulant platelet response to thrombin (25.2% vs. 12.2%), adenosine diphosphate (ADP) (7.8% vs. 2.7%) and thrombin plus collagen (27.2% vs. 18.3%). The heightened procoagulant platelet potential in CAD patients was not associated with other markers of platelet function, including aggregation, dense granule release and activation of alpha2b beta3 integrin. Although dual antiplatelet therapy (DAPT) was associated with partial suppression of procoagulant platelets, this inhibitory effect on a patient level could not be predicted by aggregation response to ADP and was not fully suppressed by clopidogrel. Conclusions We report for the first time that procoagulant platelets can be efficiently detected in a few microliters of whole blood using the cell death marker, GSAO, and the platelet activation marker, P selectin. A heightened procoagulant platelet response may provide insight into the thrombotic risk of CAD and help identify a novel target for antiplatelet therapies in CAD.

Additionally, the high reactivity of the PDA surface allowed facile linkage with reduction-responsive prodrugs and polyethylene glycol chains for in vivo chemotherapy of cancer. Under the magnetic resonance imaging/photoacoustic imaging dual-modal tumor imaging and active magnetic tumor targeting of the nanoagents in vivo, the effective tumor eradication was achieved via synergetic NIR photothermal ablation and anticancer drug delivery.

AB - Structural colors from cholesteric liquid crystals (CLCs) are manipulated by changing the only surface anchoring energy of an alignment layer. This behavior comes from the fact that weak surface energy of the perfluoropolymer induces the tilting of the cholesteric helix. Such deformed CLC structures with durability are successfully demonstrated without any external field applications and additional solidification processes. In addition, electrical tunings of structural colors from the deformed CLCs occur at very low operating voltages, compared to those of conventional CLC structures. On the basis of easy and simple fabrication, high durability, electrical tunability at low operating voltages, and the unique optical characteristics, the new deformed CLC structure could lead to extension in applications of CLCs, including multifunctional sensors, displays, and lasers.

AB - Three triple bond-conjugated naphthalene diimide (NDI) copolymers, poly{[ N, N' bis(2-R1)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]- alt-[(2,5-bis(2-R2) 1,4-phenylene)bis(ethyn-2,1-diyl)]} (PNDIR1-R2), were synthesized via Sonogashira coupling polymerization with varying alkyl side chains at the nitrogen atoms of the imide ring and 2,5-positions of the 1,4-diethynylbenzene moiety. Considering their identical polymer backbone structures, the side chains were found to have a strong influence on the surface morphology/nanostructure, thus playing a critical role in charge-transporting properties of the three NDI-based copolymers. Among the polymers, the one with an octyldodecyl (OD) chain at the nitrogen atoms of imide ring and a hexadecyloxy (HO) chain at the 2,5-positions of 1,4 diethynylbenzene, P(NDIOD-HO), exhibited the highest electron mobility of 0.016 cm2 V-1 s-1, as compared to NDI-based copolymers with an ethylhexyl chain at the 2,5-positions of 1,4-diethynylbenzene. The enhanced charge mobility in the P(NDIOD-HO) layers is attributed to the well-aligned nano-fiber-like surface morphology and highly ordered packing structure with a dominant edge-on orientation, thus enabling efficient in-plane charge transport. Our results on the molecular structure-charge transport property relationship in these materials may provide an insight into novel design of n-type conjugated polymers for applications in the organic electronics of the future.

AB - Because chiral carboxylic acids (CCAs) are a class of important biological molecules and common functional moieties found in pharmaceutical molecules, the chiral analysis of CCAs has received much attention. Herein, we developed a simple, rapid, and cost-effective method for visual and colorimetric high throughput analysis of CCAs using chiral di-imine structure-modified gold nanoparticles (C-AuNPs) as the probe. The C-AuNPs are positively charged in the presence of zinc ion, and they can be enantioselectively shielded by the negatively charged CCA enantiomers. Therefore, upon the addition of different concentrations and enantiomeric excess (ee) of CCAs, the C-AuNP-based sensor shows the different levels of aggregation along with the visual changes in solution color, which can achieve simultaneous analysis of the concentration and ee of CCAs. The chiral recognition mechanism based on C-AuNPs was investigated by the determination of binding constants ( K) and molecular simulation methods. Our approach is expected to have the wide-ranging applications in the developing region for enantio-sensing of various chiral drugs and biomolecules. PMID- 29569435 TI - Overcoming Multidrug Resistance through the GLUT1-Mediated and Enzyme-Triggered Mitochondrial Targeting Conjugate with Redox-Sensitive Paclitaxel Release. AB - Multidrug resistance (MDR) is thought to be the major obstacle leading to the failure of paclitaxel (PTX) chemotherapy. To solve this problem, a glucose transporter-mediated and matrix metalloproteinase 2 (MMP2)-triggered mitochondrion-targeting conjugate [glucose-polyethylene glycol (PEG)-peptide triphenylphosponium-polyamidoamine (PAMAM)-PTX] composed of a PAMAM dendrimer and enzymatic detachable glucose-PEG was constructed for mitochondrial delivery of PTX. The conjugate was characterized by a 30 nm sphere particle, MMP2-sensitive PEG outer layer detachment from PAMAM, and glutathione (GSH)-sensitive PTX release. It showed higher cellular uptake both in glucose transporter 1 (GLUT1) overexpressing MCF-7/MDR monolayer cell (2D) and multicellular tumor spheroids (3D). The subcellular location study showed that it could specifically accumulate in the mitochondria. Moreover, it exhibited higher cytotoxicity against MCF-7/MDR cells, which significantly reverse the MDR of MCF-7/MDR cells. The MDR reverse might be caused by reducing the ATP content through destroying the mitochondrial membrane as well as by down-regulating P-gp expression. In vivo imaging and tissue distribution indicated more conjugate accumulated in the tumor of the tumor-bearing mice model. Consequently, the conjugate showed better tumor inhibition rate and lower body weight loss, which demonstrated that it possessed high efficiency and low toxicity. This study provides glucose-mediated GLUT targeting, MMP2-responsive PEG detachment, triphenylphosponium-mediated mitochondria targeting, and a GSH-sensitive intracellular drug release conjugate that has the potential to be exploited for overcoming MDR of PTX. PMID- 29569436 TI - Macro-SICM: A Scanning Ion Conductance Microscope for Large-Range Imaging. AB - The scanning ion conductance microscope (SICM) is a versatile, high-resolution imaging technique that uses an electrolyte-filled nanopipet as a probe. Its noncontact imaging principle makes the SICM uniquely suited for the investigation of soft and delicate surface structures in a liquid environment. The SICM has found an ever-increasing number of applications in chemistry, physics, and biology. However, a drawback of conventional SICMs is their relatively small scan range (typically 100 MUm * 100 MUm in the lateral and 10 MUm in the vertical direction). We have developed a Macro-SICM with an exceedingly large scan range of 25 mm * 25 mm in the lateral and 0.25 mm in the vertical direction. We demonstrate the high versatility of the Macro-SICM by imaging at different length scales: from centimeters (fingerprint, coin) to millimeters (bovine tongue tissue, insect wing) to micrometers (cellular extensions). We applied the Macro SICM to the study of collective cell migration in epithelial wound healing. PMID- 29569437 TI - Quantitative Profiling of Protein Carbonylations in Ferroptosis by an Aniline Derived Probe. AB - Ferroptosis is a regulated form of necrotic cell death implicated in carcinogenesis and neurodegeneration that is driven by phospholipid peroxidation. Lipid-derived electrophiles (LDEs) generated during this process can covalently modify proteins ("carbonylation") and affect their functions. Here we report the development of a quantitative chemoproteomic method to profile carbonylations in ferroptosis by an aniline-derived probe. Using the method, we established a global portrait of protein carbonylations in ferroptosis with >400 endogenously modified proteins and for the first time, identified >20 residue sites with endogenous LDE modifications in ferroptotic cells. Specifically, we discovered and validated a novel cysteine site of modification on voltage-dependent anion selective channel protein 2 (VDAC2) that might play an important role in sensitizing LDE signals and mediating ferroptosis. Our results will contribute to the understanding of ferroptotic signaling and pathogenesis and provide potential biomarkers for ferroptosis detection. PMID- 29569438 TI - Tunable Plasmonic Cavity for Label-free Detection of Small Molecules. AB - Owing to its high sensitivity and high selectivity along with rapid response time, plasmonic detection has gained considerable interest in a wide variety of sensing applications. To improve the fieldwork applicability and reliability of plasmonic detection, the integration of plasmonic nanoparticles into optical devices is desirable. Herein, we propose an integrated label-free detection platform comprising a plasmonic cavity that allows sensitive molecular detection via either surface-enhanced Raman scattering (SERS) or plasmon resonance energy transfer (PRET). A small droplet of metal ion solution spontaneously produces a plasmonic cavity on the surface of uncured poly(dimethylsiloxane) (PDMS), and as PDMS is cured, the metal ions are reduced to form a plasmonic antennae array on the cavity surface. Unique spherical feature and the integrated metallic nanoparticles of the cavity provide excellent optical functions to focus the incident light in the cavity and to rescatter the light absorbed by the nanoparticles. The optical properties of the plasmonic cavity for SERS or PRET are optimized by controlling the composition, size, and density of the metal nanoparticles. By using the cavity, we accomplish both 1000-fold sensitive detection and real-time monitoring of reactive oxygen species secreted by live cells via PRET. In addition, we achieve sensitive detection of trace amounts of toxic environmental molecules such as 5-chloro-2-methyl-4-isothiazolin-3-one/2 methyl-4-isothiazol-3-one (CMIT/MIT) and bisphenol A, as well as several small biomolecules such as glucose, adenine, and tryptophan, via SERS. PMID- 29569439 TI - Critical Role of Vertical Phase Separation in Small-Molecule Organic Solar Cells. AB - An inverted device structure is a more stable configuration than a regular device structure for solution-processed organic solar cells (OSCs). However, most of the solution-processed small-molecule OSCs (SM-OSCs) reported in the literature used the regular device structure, and a regular device normally exhibits a higher efficiency than an inverted device. Herein, a representative small-molecule DR3TBDTT was selected to figure out the reason for photovoltaic performance differences between regular and inverted devices. The mechanisms for a reduced open-circuit voltage ( Voc) and fill factor (FF) in the inverted device were studied. The reduced Voc and FF is due to the vertical phase separation with excess [6,6]-phenyl-C71-butyric acid methyl ester near the air/blend surface, which leads to a reduction in build-in voltage and unbalanced charge transport in the inverted device. Another reason for the reduced FF is the unfavorable DR3TBDTT crystallite orientation distribution along the film thickness, which is preferential edge-on crystallites in the top layer of the blend film and the increased population of face-on crystallites in the bottom layer of the blend film. This study illustrates that the morphology plays a key role in photovoltaic performance difference between regular and inverted devices and provides useful guidelines for further optimization of the morphology of solution-processed SM OSCs. PMID- 29569440 TI - Transparent Polymeric Films Capable of Healing Millimeter-Scale Cuts. AB - Transparent polymeric films have been successfully integrated with self-healing capabilities. However, these films can only heal damages in the scale of several to several tens of micrometers, thereby greatly limiting their practical applications. The present study reports the fabrication of transparent polymeric films capable of healing millimeter-scale cuts by incorporating hydrogen-bonding units into zwitterionic polymer films, which are cross-linked by electrostatic interactions. The intermolecular interactions in the resulting films are greatly reduced when the films absorb water as a result of the reversibility of hydrogen bonding and electrostatic interactions, thereby promoting the flowability of the film materials. Thus, the transparent films can heal 7.9 mm wide cuts and recover their damaged transparency following exposure to water. Furthermore, owing to their strong binding affinity to water molecules, the healable transparent films can effectively clean up oil fouled on dry films following rinsing with water. The combination of hydrogen bonding and electrostatic interactions provides a new means of design for transparent films with enhanced healing capabilities and an extended service life. PMID- 29569442 TI - Brominated Flame Retardants and Organophosphate Esters in Preschool Dust and Children's Hand Wipes. AB - Children spend a considerable part of their day in preschool, where they may be exposed to hazardous chemicals in indoor dust. In this study, brominated flame retardants (BFRs) and organophosphate esters (OPEs) were analyzed in preschool dust ( n = 100) and children's hand wipe samples ( n = 100), and diphenyl phosphate (DPHP) was analyzed in urine ( n = 113). Here we assessed children's exposure via dust, identified predictors for chemicals in dust, and studied correlations between different exposure measures. The most abundant BFRs in dust were decabromodiphenyl ether (BDE-209) and decabromodiphenyl ethane (DBDPE) found at median levels of 270 and 110 ng/g dust, respectively. Tris(2-butoxyethyl) phosphate (TBOEP) was the most abundant OPE, found at a median level of 79 000 ng/g dust. For all OPEs and some BFRs, there were significant correlations between the levels in dust and hand wipes. In addition, triphenyl phosphate (TPHP) in preschool dust was significantly correlated with the corresponding metabolite DPHP in children's urine. The levels of pentaBDEs in dust were higher in older preschools compared with newer, whereas levels of DBDPE were higher in newer preschools. Children's estimated intakes of individual BFRs and OPEs via preschool dust were below available health-based reference values. However, there are uncertainties about the potential health effects of some emerging BFRs and OPEs. PMID- 29569441 TI - Reentrant Phase Transitions and Non-Equilibrium Dynamics in Membraneless Organelles. AB - Compartmentalization of biochemical components, interactions, and reactions is critical for the function of cells. While intracellular partitioning of molecules via membranes has been extensively studied, there has been an expanding focus in recent years on the critical cellular roles and biophysical mechanisms of action of membraneless organelles (MLOs) such as the nucleolus. In this context, a substantial body of recent work has demonstrated that liquid-liquid phase separation plays a key role in MLO formation. However, less is known about MLO dissociation, with phosphorylation being the primary mechanism demonstrated thus far. In this Perspective, we focus on another mechanism for MLO dissociation that has been described in recent work, namely a reentrant phase transition (RPT). This concept, which emerges from the polymer physics field, provides a mechanistic basis for both formation and dissolution of MLOs by monotonic tuning of RNA concentration, which is an outcome of cellular processes such as transcription. Furthermore, the RPT model also predicts the formation of dynamic substructures (vacuoles) of the kind that have been observed in cellular MLOs. We end with a discussion of future directions in terms of open questions and methods that can be used to answer them, including further exploration of RPTs in vitro, in cells, and in vivo using ensemble and single-molecule methods as well as theory and computation. We anticipate that continued studies will further illuminate the important roles of reentrant phase transitions and associated non equilibrium dynamics in the spatial patterning of the biochemistry and biology of the cell. PMID- 29569443 TI - Near-Infrared-Emitting CuInS2/ZnS Dot-in-Rod Colloidal Heteronanorods by Seeded Growth. AB - Synthesis protocols for anisotropic CuInX2 (X = S, Se, Te)-based heteronanocrystals (HNCs) are scarce due to the difficulty in balancing the reactivities of multiple precursors and the high solid-state diffusion rates of the cations involved in the CuInX2 lattice. In this work, we report a multistep seeded growth synthesis protocol that yields colloidal wurtzite CuInS2/ZnS dot core/rod shell HNCs with photoluminescence in the NIR (~800 nm). The wurtzite CuInS2 NCs used as seeds are obtained by topotactic partial Cu+ for In3+ cation exchange in template Cu2- xS NCs. The seed NCs are injected in a hot solution of zinc oleate and hexadecylamine in octadecene, 20 s after the injection of sulfur in octadecene. This results in heteroepitaxial growth of wurtzite ZnS primarily on the Sulfur-terminated polar facet of the CuInS2 seed NCs, the other facets being overcoated only by a thin (~1 monolayer) shell. The fast (~21 nm/min) asymmetric axial growth of the nanorod proceeds by addition of [ZnS] monomer units, so that the polarity of the terminal (002) facet is preserved throughout the growth. The delayed injection of the CuInS2 seed NCs is crucial to allow the concentration of [ZnS] monomers to build up, thereby maximizing the anisotropic heteroepitaxial growth rates while minimizing the rates of competing processes (etching, cation exchange, alloying). Nevertheless, a mild etching still occurred, likely prior to the onset of heteroepitaxial overgrowth, shrinking the core size from 5.5 to ~4 nm. The insights provided by this work open up new possibilities in designing multifunctional Cu-chalcogenide based colloidal heteronanocrystals.

AB - A general photoredox-catalyzed intramolecular cyclization was developed for the synthesis of trifluoromethylated heterocyclic compounds. The reaction proceeded smoothly under mild photocatalytic conditions with high functional group tolerance, allowing the preparation of oxygen-, sulfur-, or nitrogen-containing heterocycles of different sizes. The broad substrate scope demonstrated the complexity-building potential of the strategy. PMID- 29569445 TI - Adversarial Threshold Neural Computer for Molecular de Novo Design. AB - In this article, we propose the deep neural network Adversarial Threshold Neural Computer (ATNC). The ATNC model is intended for the de novo design of novel small molecule organic structures. The model is based on generative adversarial network architecture and reinforcement learning. ATNC uses a Differentiable Neural Computer as a generator and has a new specific block, called adversarial threshold (AT). AT acts as a filter between the agent (generator) and the environment (discriminator + objective reward functions). Furthermore, to generate more diverse molecules we introduce a new objective reward function named Internal Diversity Clustering (IDC). In this work, ATNC is tested and compared with the ORGANIC model. Both models were trained on the SMILES string representation of the molecules, using four objective functions (internal similarity, Muegge druglikeness filter, presence or absence of sp3-rich fragments, and IDC). The SMILES representations of 15K druglike molecules from the ChemDiv collection were used as a training data set. For the different functions, ATNC outperforms ORGANIC. Combined with the IDC, ATNC generates 72% of valid and 77% of unique SMILES strings, while ORGANIC generates only 7% of valid and 86% of unique SMILES strings. For each set of molecules generated by ATNC and ORGANIC, we analyzed distributions of four molecular descriptors (number of atoms, molecular weight, logP, and tpsa) and calculated five chemical statistical features (internal diversity, number of unique heterocycles, number of clusters, number of singletons, and number of compounds that have not been passed through medicinal chemistry filters). Analysis of key molecular descriptors and chemical statistical features demonstrated that the molecules generated by ATNC elicited better druglikeness properties. We also performed in vitro validation of the molecules generated by ATNC; results indicated that ATNC is an effective method for producing hit compounds. PMID- 29569446 TI - WHO: healthy diet to prevent chronic diseases and caries. AB - For some years now, the WHO has recommended less than 10% of energy intake from free sugars. The same document also stresses the need to bring this limit below 5% as soon as possible. These guidelines have been promoted with the aim of reducing the prevalence of chronic non-communicable diseases such as diabetes, cardiovascular disease, obesity and metabolic syndrome. At the same time, the reduction of free sugars in the diet can be part of a strategy to reduce the prevalence of caries, which is known to be an infectious and transmissible multifactorial disease known to be "triggered" by wrong dietary habits. For this reason, paediatricians and paediatric dentists should combine their efforts to promote good eating habits from an early age and perhaps even earlier! In fact, we should teach future mothers and their children to prefer slowly absorbed sugars and drastically reduce the intake of free sugars with the diet. As soon as the child is able to chew, the diet should include fibre-rich foods, and water should be preferred over any sweetened drink. Raising children with a healthy and balanced diet means investing in his or her long-term general health and offer a dental future free of caries! PMID- 29569447 TI - Association between salivary cortisol level and caries in early childhood. AB - AIM: The present study aimed to evaluate the association between caries and oral health status, age, salivary cortisol levels, and parental education in children with and without prior dental caries experience. MATERIALS AND METHODS: An observational case-control study was performed including 122 children aged between 3 and 6 years who were clinically examined for caries experience using the sum of decayed, missing, and filled teeth in the primary (dmft index) and permanent (DMFT index) dentition. Oral health status was also evaluated using the Simplified Oral Hygiene index (OHI-S). Parents filled a questionnaire to provide information on other variables. Salivary cortisol levels were estimated 1 h after routine dental brushing. RESULTS: We found that dental caries experience was associated with cortisol level, plaque, age, and high calculus levels. High cortisol levels and age are important risk factors for caries development with odds ratios of 3.05 (95% CI: 1.84-5.06) and 1.59 (95% CI: 1.09-2.58), respectively. Multivariate logistic analysis showed that cortisol level and age were independently associated with caries presence. Caries experience was not associated with education of parents, feeding-hygiene habits of child or birth events. CONCLUSION: The present findings support the hypothesis that caries is mainly correlated with high salivary cortisol levels. Dental caries experience in children was also positively associated with tartar, plaque, and age. PMID- 29569448 TI - Apical extrusion of debris in primary molar root canals using mechanical and manual systems. AB - AIM: Apical extrusion of debris in primary root canal treatment has not been well elucidated. The purpose of this study is to compare the amount of apically extruded debris during the preparation of primary molar root canals using ProTaper, ProTaper Next, Self-adjusting File (SAF) and hand files. MATERIALS AND METHODS: One hundred sixty extracted primary mandibular molar teeth were assigned to 2 groups: Group 1: Resorbed (n=80) and Group 2: Non-resorbed (n=80) and randomly to four subgroups (n=20 teeth for each subgroup) according to the instruments used, ProTaper, ProTaper Next, SAF, and hand file. The apically extruded debris was collected and dried in preweighed Eppendof tubes. The dry weight was calculated by subtracting the preoperative weight from the postoperative weight. STATISTICS: Data were analysed statistically using the ANOVA and the Bonferroni post hoc t-test. RESULTS: The amount of apically extruded debris was significantly less for the non-resorbed group compared to the resorbed group (P<0.05). Regardless of the resorption groups, ProTaper Next and SAF extruded significantly less debris than did the ProTaper and hand files (P<0.05), while no statistically significant difference was found between ProTaper Next and SAF (P>0.05). CONCLUSION: All instruments caused apically extruded debris in primary teeth. PMID- 29569449 TI - Parental-caregiver perception of child oral-health related quality of life following zirconia crown placement and non-restoration of carious primary anterior teeth. AB - AIM: Dental caries in preschool children has shown significant impact on children's OHRQoL and family functioning. The aim of this study was to measure parents' perceptions of children's OHRQoL and impact of children's orofacial conditions on the family following management of carious anterior teeth with either zirconia crown placement or non-restorative therapy. MATERIALS AND METHODS: Parents of medically fit children aged from 2 years to 6 years attending specialist paediatric clinics were recruited and a questionnaire that included the Global Oral Health Rating Item, Parent-Caregivers Perception Questionnaire (P CPQ-8) and Family Impact Scale (FIS-8) was distributed at a recall visit 3-6 months following treatment. Twenty patients were allocated in each of the two groups; zirconia crown and non-restorative therapy. RESULTS: The Global Oral Health Rating item scores were significantly different between groups (p=0.038). Children health effects due to dental status were more among patients treated with zirconia crowns. However, PCPQ and FIS total and individual scores were not significantly different between groups (p>0.05) except that children suffered more food impaction between teeth among patients treated with zirconia crowns (p=0.002). CONCLUSIONS: Parents' perceptions of children's OHRQoL and impact on family were similar when anterior carious teeth were managed with zirconia crown placement or non-restorative therapy. PMID- 29569450 TI - Maxillary tridimensional changes after slow expansion with leaf expander in a sample of growing patients: a pilot study. AB - AIM: The aim of this study is to evaluate the dento-alveolar effects of slow maxillary expansion using the Leaf Expander in a sample of growing patients with maxillary transverse deficiency, unilateral cross bite and mandibular shift. MATERIALS AND METHODS: The study included 10 patients, 3 male and 7 female (mean age 7.5 + 7 months), treated with Leaf Expander anchored on the upper deciduous teeth. Digital models were obtained by a lab scan of the pvs impressions at the beginning of the therapy (T1) and at the removal of the palatal expander (T2). Five parameters were measured: 1) the distance between the first upper permanent molars; 2) the distance between the upper second deciduous molars; 3) the distance between the upper canine cusps 4) the distance between the first lower permanent molars; 5) the distance of the lower canine cusps. RESULTS: In all patients complete correction of posterior crossbite was achieved on average in 4 months, with a spontaneous expansion of the upper first permanent molars. Significant increases in the dento-alveolar transversal diameters were obtained. Increases were also observed in the anterior mandibular arch diameter (+ 1 mm). CONCLUSIONS: These findings suggest that slow maxillary expansion using Leaf Expander appliance could be a reasonable alternative to conventional maxillary expansion therapy in the early mixed dentition. PMID- 29569451 TI - A comparative assessment of changes in dental arches associated with different activation protocols of rapid maxillary expansion. AB - AIM: The aim of this study is to compare dental arch changes associated with different activation protocols of maxillary expander. MATERIALS AND METHODS: A sample of 101 subjects with constricted maxillary arches (49 males and 52 females; mean age 10.96 +/- 1.91 years) was enrolled in the study. All subjects underwent RME with a stainless steel banded expander cemented to the maxillary first molars and the expansion screw was randomly activated with two different rapid maxillary expansion protocols (one- quarter per day or two quarters per day). The study also involved a control group of 22 subjects (10 females and 12 males, mean age 10.39 +/- 1.32 years) who underwent no treatment. A statistical comparison between the dental arch measures obtained before and after treatment in the two groups was performed. RESULTS: The Wilcoxon rank-sum test shows statistically significant differences of the measurement increases between the two activation protocols (at least p=0.01). Statistically significant differences were also reported in comparison with the control group. CONCLUSIONS: A faster activation protocol could be able to determine a greater anterior opening of the mid-palatal suture. Moreover, it seems to yield a higher width increase in the molar area. PMID- 29569452 TI - Single tooth anaesthesia: a new approach to the paediatric patient. A clinical experimental study. AB - AIM: The objective of this study is to assess the efficacy of the STA Wand System with respect to pain and fear reduction in paediatric patients and by using the Single Tooth Anaesthesia (STA) technique. MATERIALS AND METHODS: Patients included children and teenagers between 6 and 17 years of age, who required the administration of local anaesthesia prior to expected treatments. Local anaesthesia was performed by means of the electronic STA Wand System (Milestone scientific., Inc.) adopting the Single Tooth Anaesthesia (STA) technique. Pre- and post-anaesthesia, the patients were asked to complete the Wong-Baker faces image scale and the provider filled in the Frankl Scale. RESULTS: All treatments were completed successfully and no collaboration issues were recorded. Frankl's assessment showed that 91% of patients regarded dental experience positively. The efficacy of the computer-assisted anaesthesia was at 100% when treating primary teeth, and 70% for procedures on permanent teeth. Almost the totality of treated patients (94%) gave a positive evaluation after having tried the device with STA technique. Only 6% of the patients assessed the procedure negatively. CONCLUSIONS: The STA technique allows for absence of anticipatory anxiety, absence of physical pain, no anaesthetic effects in the perioral tissues and a controllable, lower dosage of the anaesthetic liquid. PMID- 29569453 TI - The safety of paediatric dentistry procedures under general anaesthesia. A five year experience of a tertiary care center. AB - AIM: Frequently general anaesthesia (GA) is used to treat noncompliant children. Especially in children with morbid diseases general anaesthesia can be a challenging procedure for anaesthetists. The aim of this paper was to evaluate the risks and adverse reactions with a special focus on the impact of existing medication conditions and syndromes. MATERIALS AND METHODS: and methods Records of children up to 10 years of age, who were admitted for paediatric dentistry procedures under GA from January 2011 to December 2016 at the University Hospital of the University of Aachen (Germany), were reviewed. A special attention was paid to the intra- and perioperative critical adverse reactions and concomitant systemic conditions and their impact on treatment outcome. RESULTS: Two hundred and twenty patients were admitted for dental restorations. Critical adverse reactions occurred in 4% of the treated patients and they were statistically significantly (p=0.004) related to the ASA classification above II. The use of a laryngeal mask airway was significantly associated (p<0.001) with a shorter duration of surgery. Most common concomitant medical conditions were congenital heart disease, mental retardation and inherited syndromes. CONCLUSION: Although the administration of general anaesthesia in infants and children can be regarded as a safe procedure, clinically significant adverse reactions can occur, especially in patients with an existing medical condition. PMID- 29569454 TI - The possibility of modification and improvement of dental services in Poland for children and adolescents with special emphasis on orthodontic service. AB - AIM: World Dental Federation reveals that dental caries is one of the most common diseases in the world, and as much as 90% of the population is facing oral cavity problems. About 28% of teenagers aged 10 and 15 absolutely needs orthodontic treatment and about another third of this age group represents very serious cases. The aim of this study is to verify the authorial model which modifies and facilitates the system of dental services in Poland with a special emphasis on orthodontic service. MATERIAL AND METHODS: The research was carried out with the method of diagnostic survey through a survey questionnaire. For this study, 1159 people were questioned for the research. In order to check the reliance between the variables Pearson chi-square test and the test of the Highest Reliability were used. Average market prices and the "prices expected" by the Greater Poland Voivodship Department of National Healthcare System were used to price dental services. RESULTS: The research revealed that the highest percentage of people who used only private dental services is between 19 and 64 years of age and the lowest percentage is represented by the elderly, i.e. subjects over 65 years of age. As for the dental services offered by the National Health Fund, the highest percentage of patients are children and adolescents under 18 and the lowest percentage of patients is represented by people in the working age. The tendency towards private healthcare is in direct proportion to parents' increase in the level of education. The main reason why parents take their children to a private dentist is the long waiting time for the visit offered by the National Health Fund as well as better materials and equipment offered by private dentists. The costs connected with extending the basket of guaranteed services for children and youngsters are combined with the increase in National Health Fund expenditure reaching EUR 7,014,151. The lack of refunding dental services for patients aged 19-64 will generate savings reaching about EUR 34,756,765. CONCLUSION: The reduction of public funds allocated for dental treatment of patients aged 19-64 will generate savings which will satisfy the needs connected with the increase in the range of refunded orthodontic treatment with the use of orthodontic permanent braces for patients under 18 years of age. The solution suggested will only slightly affect people in the working age as they reveal a strong tendency for treatment financed with their private funds. PMID- 29569455 TI - Laser labial frenectomy: a simplified and predictable technique. Retrospective clinical study. AB - AIM: Anomalous maxillary median labial frenum may be associated with undesired effects such as persistence of diastema between anterior teeth or traction of marginal gingiva. The aim of this study was to propose a surgical frenum repositioning technique that is minimally invasive, safe, easy, reproducible, and predictable. Another objective of the study was to identify clinical scenarios that could have indication for labial frenectomy associated with early orthodontic therapy, so as to justify early frenum repositioning in children. A retrospective assessment of clinical outcomes of this technique is described. MATERIALS AND METHODS: A total of 20 frenectomies were performed on children aged 8 to 10 years. Frenectomies were performed with Er:YAG laser set at 150mJ 2.25 3.0W and 15-20 pulse per second, with water spray. Recall visits were done at 7, 21 and 90 days and 1, 2, 3 and 4 years. RESULTS: At post-operative visits, all patients reported no post-operative pain or minimal discomfort. None experienced post-operative bleeding at a distance of few hours. All patients reported that the procedure was well tolerated and "acceptable". No recurrences occurred 4 years after frenectomy. CONCLUSION: The Er:YAG laser used in this study allowed considerable reduction of the operating time, reducing the amount of local anaesthetic used as well as avoiding surgical sutures. The surgical design and technique also minimised post-operative discomfort and complications resulting in stable healing overtime, making the procedure fully accepted by children. PMID- 29569456 TI - Is laser conditioning a valid alternative to conventional etching for aesthetic brackets? AB - AIM: ER:Yag lasers have been described as a more conservative alternative to conventional acid-etching enamel conditioning technique, when bonding conventional metallic orthodontic brackets. Since the use of aesthetic orthodontic brackets is constantly increasing, the purpose of the present report has been to test laser conditioning with different aesthetic brackets. MATERIALS AND METHODS: Study Design: Five different aesthetic brackets (microfilled copolymer, glass fiber, sapphire, polyoxymethylene and sintered ceramic) were tested for shear bond strength and Adhesive Remnant Index scores using two different enamel conditioning techniques (acid etching and ER:Yag laser application). Two hundred bovine incisors were extracted, cleaned and embedded in resin. Specimens were then divided into 10 groups with random tables. Half of the specimens were conditioned with conventional orthophosphoric acid gel, the other half with ER:Yag laser. Different aesthetic brackets (microfilled copolymer, glass fiber, sapphire, polyoxymethylene and sintered ceramic) were then bonded to the teeth. Subsequently all groups were tested in shear mode with a Universal Testing Machine. Shear bond strength values and adhesive remnant index scores were recorded. Statistical analysis was performed. RESULTS: When considering conventional acid etching technique, sapphire, polyoxymethylene and sintered ceramic brackets exhibited the highest SBS values. Lowest values were reported for microfilled copolymer and glass fiber appliances. A significant decrease in SBS values after laser conditioning was reported for sapphire, polyoxymethylene and sintered ceramic brackets, whereas no significant difference was reported for microfilled copolymer and glass fiber brackets. Significant differences in ARI scores were also reported. CONCLUSIONS: Laser etching can significantly reduce bonding efficacy of sapphire, polyoxymethylene and sintered ceramic brackets. PMID- 29569457 TI - Titanium TSME appliance for patients allergic to nickel. AB - AIM: The aim of this article is to describe the use of a titanium TSME appliance for patients with allergy to resin and nickel. We aim to highlight the optimal way to avoid problems such as stomatitis and peri-labial dermatitis, which generally appear in patients who use traditional orthodontic appliances made in acrylic resin and steel. MATERIALS AND METHODS: The construction of a titanium appliance is described and a case treated with it is reported. RESULTS: The titanium TSME presented in this paper has excellent biocompatibility due to its ability to form superficial oxides, which prevent oxidation and thus corrosion. CONCLUSION: The non-allergic properties of titanium allow to propose it as an alternative in patients with a long-term history of allergic reactions to nichel. PMID- 29569458 TI - Clinical, histomorphological and therapeutic features of the Van der Woude Syndrome: literature review and presentation of an unusual case. AB - BACKGROUND: Van der Woude syndrome (VWS), an autosomal dominant condition associated with lower lip pits and/or cleft palate, is caused by mutations in the interferon regulatory factor 6 gene (lRF6 gene). The genetic alterations identified to date that contribute to expression of the syndrome are chiefly mutations located on chromosome 1 (the largest of our chromosomes), mutations at p36 that codifies the gene GRHL (grainy-head transcriptor factor) and mutations involving IRF6 (interferon regulatory factor). With frequency ranging from 1:35,000 to 1:100,000, depending on ethnicity, gender, and socio-economic status, the syndrome accounts for about 2% of orofacial clefts. The clinical and histomorphological aspects of VWS are studied, and a case of heterozygous female twins of whom only one was affected with VWS is reported. CONCLUSION: This very rare case (no similar case has been reported to date) contributes further evidence on modifying factors in the expression of this condition. PMID- 29569459 TI - A video eyeglasses/earphones system as distracting method during dental treatment in children: A crossover randomised and controlled clinical trial. AB - : AIM To evaluate the effectiveness of a Video Eyeglasses/Earphones System (VEES) as distracting device in reducing anxiety in children during dental procedures carried out under local anaesthesia. MATERIALS AND METHODS: In this crossover clinical trial, 36 Frankl scale II and III children aged 5-8 years received different dental procedures in two sessions, with and without the VEES system. In the control visit, they were not exposed to this distraction stimulus, but traditional non-aversive behaviour management was applied. Each dental session was divided into four phases (explanation, anaesthetic injection, rubber dam/clamp placement, and high-speed hand piece work for 5 min). Pain in each treatment phase was assessed by the following measurements: the Face, Legs, Activity, Cry, Consolability (FLACC) scale. Pulse rate, and oxygen saturation measurements were employed to evaluate the state of anxiety. Comparison of the outcomes of two interventions were statistically analysed through the Wilcoxon Signed-rank Test. RESULTS: There were no statistical differences between the results of the two interventions (VEES vs. no VEES/behavioural management) during the four treatment phases on assessment by any of the measurements employed. CONCLUSIONS: The VEES method was not more effective than traditional non-aversive behavioural techniques for reducing anxiety and pain perception in children undergoing dental treatment. PMID- 29569460 TI - Dental Sealants. Part 1: Prevention First. AB - BACKGROUND: Tooth decay is still one of the most common chronic childhood diseases in the world, even if during the last five decades measures to combat dental caries have been developed, tested and applied in many populations. Preventive care and education programmes are essential to keeping children's mouths healthy. Within the prevention methods, dental sealants play an important role in preventing the onset and the development of dental cavities. PMID- 29569461 TI - Influence of Occupational Socialization on the Perspectives and Practices of Adapted Physical Education Teachers. AB - The purpose of this study was to describe and examine the occupational socialization of nine adapted physical educators (APEs). The questions we attempted to answer were (a) What were the perspectives and practices of the APEs? and (b) What factors influenced these perspectives and practices? Data were collected through six qualitative techniques and analyzed by using analytic induction and constant comparison. At the time the study was conducted, the APEs possessed traditional or progressive teaching orientations. They had been attracted to a career as an APE through their participation in sport and physical activity and interactions with persons with disabilities. The quality of adapted physical education teacher education the APEs received varied, but high-quality adapted physical education teacher education appeared to exert a powerful influence on their values and pedagogies. The school cultures and conditions in which the APEs worked on entry into the workforce either served to support or negate their programs. We conclude the paper by providing several hypotheses regarding the influences of occupational socialization on in-service APEs' teaching. PMID- 29569462 TI - Conceptualizing Obesity as a Chronic Disease: An Interview With Dr. Arya Sharma. AB - Dr. Arya M. Sharma challenges the conventional wisdom of relying simply on "lifestyle" approaches involving exercise, diet, and behavioral interventions for managing obesity, suggesting that people living with obesity should receive comprehensive medical interventions similar to the approach taken for other chronic diseases such as Type 2 diabetes or hypertension. He purports that the stigma-inducing focus on self-failing (e.g., coping through food, laziness, lack of self-regulation) does not address biological processes that make obesity a lifelong problem for which there is no easy solution. Interdisciplinary approaches to obesity are advocated, including that of adapted physical activity. Physical activity has multifaceted impacts beyond increasing caloric expenditure, including improved sleep, better mood, increased energy levels, enhanced self esteem, reduced stress, and an enhanced sense of well-being. The interview with Dr. Sharma, transcribed from a keynote address delivered at the North American Adapted Physical Activity Symposium on September 22, 2016, in Edmonton, AB, Canada, outlines his rationale for approaching obesity as a chronic disease. PMID- 29569463 TI - Gradient-echo-based 3D submillisecond echo time pulmonary MR imaging: a preliminary usability study on clinical and preclinical MR scanners. AB - OBJECTIVE: To preliminarily investigate a technical feasibility of a submillisecond echo time concurrent-dephasing-and-excitation (CODE) sequence for pulmonary MRI on clinical and preclinical MR scanners Methods: CODE imaging (echo time, 0.14 ~ 0.18 ms) was performed with American College of Radiology phantom at 3 T, 7 healthy volunteers at 1.5 and 3 T, 10 rabbits at 3 T, and 2 rodents at 9.4 T. Signal-to-noise ratio was compared in phantom. Image quality of human MRI was visually assessed on a 5-point scale for comparison between CODE and conventional lung MRI sequences. Visibility of bronchi, subcentimeter nodules, and MR air bronchogram were assessed in animal studies. RESULTS: In phantom study, signal-to noise ratio was higher with CODE than with original three-dimensional ultrashort echo time sequence (106.71 +/- 4.32 vs 91.66 +/- 3.54; p < 0.001). Image quality of human MRI was better with CODE than with conventional MRI sequences (p <= 0.002). Bronchi remained traceable up to the fifth bronchial generation in CODE images in rabbits and rodents. 95.2% of metastatic nodules (diameter, 1.5 +/- 0.4 mm) and 93.8% of MR air-bronchogram (diameter, 0.9 +/- 0.2 mm) in rabbits. CONCLUSION: Submillisecond echo time pulmonary MRI was technically feasible by using CODE on various MR scanners. Advances in knowledge: CODE can be a practical alternative for lung MRI on both clinical and pre-clinical scanners, without challenges of free-induction-decay-based ultrashort-echo time sequences. PMID- 29569464 TI - Forensic Discrimination of Latent Fingerprints Using Laser-Induced Breakdown Spectroscopy (LIBS) and Chemometric Approaches. AB - A novel technique is reported for separating overlapping latent fingerprints using chemometric approaches that combine laser-induced breakdown spectroscopy (LIBS) and multivariate analysis. The LIBS technique provides the capability of real time analysis and high frequency scanning as well as the data regarding the chemical composition of overlapping latent fingerprints. These spectra offer valuable information for the classification and reconstruction of overlapping latent fingerprints by implementing appropriate statistical multivariate analysis. The current study employs principal component analysis and partial least square methods for the classification of latent fingerprints from the LIBS spectra. This technique was successfully demonstrated through a classification study of four distinct latent fingerprints using classification methods such as soft independent modeling of class analogy (SIMCA) and partial least squares discriminant analysis (PLS-DA). The novel method yielded an accuracy of more than 85% and was proven to be sufficiently robust. Furthermore, through laser scanning analysis at a spatial interval of 125 um, the overlapping fingerprints were reconstructed as separate two-dimensional forms.

AB - Raman spectroscopy as a fast and nondestructive technique has been used to investigate heating effects on Desi ghee during frying/cooking of food for the first time. A temperature in the range of 140-180C has been investigated within which Desi ghee can be used safely for cooking/frying without much alteration of its natural molecular composition. In addition, heating effects in case of reuse, heating for different times, and cooking inside pressure cookers are also presented. An excitation laser at 785 nm has been used to obtain Raman spectra and the range of 540-1800 cm-1 is found to contain prominent spectral bands. Prominent variations have been observed in the Raman bands of 560-770 cm-1, 790 1160 cm-1, and 1180-1285 cm-1 with the rise in temperature. The spectral variations have been verified using classifier principal component analysis. It has been found that Desi ghee can be reused if heated below 180C and it can be heated up to 30 min without any appreciable molecular changes if a controlled heating can be managed. PMID- 29569467 TI - Momentum: A Report on the 2017 Vizient Clinical Connections Summit. PMID- 29569468 TI - Relationship between uric acid levels and cardiometabolic findings in a large cohort of beta-thalassemia major patients. AB - AIM: to evaluate the relationship between uric acid (UA), hepatic and cardiac iron overload (T2*-MRI), ferritin, endocrinological diseases and cardiac complications in a large thalassemia major (TM) cohort. METHODS: A total of 369 TM patients (187 men; 33 +/- 6 years) were retrospectively studied, from the myocardial iron overload in thalassemia (MIOT) electronic databank. RESULTS: Multiple regression model identified male sex (p < 0.001), BMI (p < 0.001) and T2* (p <= 0.001) as UA independent correlates. Moreover, UA and derivatives of reactive oxygen species (an oxidative index; r = -0.3; p <= 0.05) are inversely correlated. Conversely, the multivariate logistic analysis identified low UA (NANHES-III criteria) as one independent predictor for low global heart T2* (p < 0.5) together with liver iron concentrations (>3 mg/g/dw), heart failure, endocrinopathies, ferritin (>2000 ng/l), alanine transaminase (>40 UI/l) and/or aspartate transaminase (>35 UI/l) and/or glutamyl transferase (>64 UI/l). DISCUSSION: UA appears directly associated to T2* and inversely with derivatives of reactive oxygen species, and as such reduced according to increased oxidative stress and cardiac iron overload in TM patients. PMID- 29569469 TI - Mach-Zehnder Stationary Two-Beam Spectroscopy Using Compound Prisms. AB - An interferometric optical setup for diffraction-less spectroscopy is tested as an optical design for control of interference frequency. Its design is based on a Mach-Zehnder interferometer in which a pair of compound prisms is introduced in the interferometer path to obtain interference patterns, which avoids the diffraction phenomena and nonlinear dispersion found on spectrometers that use gratings. Computer simulations of the interference patterns generated by the proposed optical setup are presented, and confirmed by the experimental results of the optical implementation. The theory that describes an ideal optical setup and the experimental results show that in order to reduce the combined uncertainties of wavelength measurement, a precise control in angle deviation and magnification are required for the reduction of measurement uncertainties. PMID- 29569470 TI - A trial based economic evaluation of occupational therapy discharge planning for older adults: the HOME randomized trial. AB - OBJECTIVE: To compare the cost effectiveness of two occupational therapy-led discharge planning interventions from the HOME trial. DESIGN: An economic evaluation was conducted within the superiority randomized HOME trial to assess the difference in costs and health-related outcomes associated with the enhanced program and the in-hospital consultation. Total costs of health and community service utilization were used to calculate incremental cost-effectiveness ratios, activities of daily living and quality-adjusted life years. SETTING: Medical and acute care wards of Australian hospitals ( n=5). SUBJECTS: A total of 400 people >= 70 years of age. INTERVENTIONS: Participants were randomized to either (1) an enhanced program (HOME), involving pre/post discharge visits and two follow-up phone calls, or (2) an in-hospital consultation using the home and community environment assessment and the Lawton Instrumental Activities of Daily Living assessment. MAIN MEASURES: Nottingham Extended Activities of Daily Living (global measure of activities of daily living) and SF-12V2, transformed into SF-6D (quality-adjusted life year) measured at baseline and three months post discharge. RESULTS: The cost of the enhanced program was higher than that of the in-hospital consultation. However, a higher proportion of patients showed improvement in activities of daily living in the enhanced program with an incremental cost-effectiveness ratio of $61,906.00 per person with clinically meaningful improvement. CONCLUSION: Health services would not save money by implementing the enhanced program as a routine intervention in medical and acute care wards. Future research should incorporate longer time horizons and consider which patient groups would benefit from home visits. PMID- 29569471 TI - Synthesis and bioactivities of diamide derivatives containing a phenazine-1 carboxamide scaffold. AB - Taking natural product phenazine-1-carboxamide (PCN) as a lead compound, a series of novel phenazine-1-carboxylic acid diamide derivatives were designed and synthesised. Their structures were confirmed by 1H-NMR and HRMS. The bioassays showed that some of the target compounds exhibited promising in vitro fungicidal activities, and exhibited excellent and selective herbicidal activities. Particularly, compounds c, h, o and s displayed root length inhibition activities against barnyard grass with the rate of more than 80%. Compound c exhibited the best activity among all the target compounds against barnyard grass stalk length with the IC50 value of 0.158 mmol/L, and compound o exhibited the best and wide spectrum inhibition against barnyard grass root length and rape in both root length and stalk length herbicidal activities with its IC50 values of 0.067, 0.048 and 0.059 mmol/L respectively. The analysis of preliminary Structure Activity Relationships provides the theoretical basis for further design of phenazine-1-carboxylic acid. PMID- 29569472 TI - Regorafenib in the treatment of metastatic colorectal cancer. AB - Regorafenib is an orally available multikinase inhibitor, currently approved in metastatic chemorefractory colorectal cancer patients. The results of two large randomized Phase III trials are available, providing significant results in overall and progression-free survival in this situation. Its use requires a special attention regarding patient selection, dosing schedule and management of adverse events. Identifying patients who will tolerate and have benefit from regorafenib is a challenge for clinicians. Therapeutic monitoring (especially cfDNA), predictive biomarkers and specific perfusion-based imaging techniques will may be result in optimizing regorafenib treatment. PMID- 29569473 TI - Neurofeedback-Based Enhancement of Single-Trial Auditory Evoked Potentials: Treatment of Auditory Verbal Hallucinations in Schizophrenia. AB - Auditory verbal hallucinations depend on a broad neurobiological network ranging from the auditory system to language as well as memory-related processes. As part of this, the auditory N100 event-related potential (ERP) component is attenuated in patients with schizophrenia, with stronger attenuation occurring during auditory verbal hallucinations. Changes in the N100 component assumingly reflect disturbed responsiveness of the auditory system toward external stimuli in schizophrenia. With this premise, we investigated the therapeutic utility of neurofeedback training to modulate the auditory-evoked N100 component in patients with schizophrenia and associated auditory verbal hallucinations. Ten patients completed electroencephalography neurofeedback training for modulation of N100 (treatment condition) or another unrelated component, P200 (control condition). On a behavioral level, only the control group showed a tendency for symptom improvement in the Positive and Negative Syndrome Scale total score in a pre /postcomparison ( t(4) = 2.71, P = .054); however, no significant differences were found in specific hallucination related symptoms ( t(7) = -0.53, P = .62). There was no significant overall effect of neurofeedback training on ERP components in our paradigm; however, we were able to identify different learning patterns, and found a correlation between learning and improvement in auditory verbal hallucination symptoms across training sessions ( r = 0.664, n = 9, P = .05). This effect results, with cautious interpretation due to the small sample size, primarily from the treatment group ( r = 0.97, n = 4, P = .03). In particular, a within-session learning parameter showed utility for predicting symptom improvement with neurofeedback training. In conclusion, patients with schizophrenia and associated auditory verbal hallucinations who exhibit a learning pattern more characterized by within-session aptitude may benefit from electroencephalography neurofeedback. Furthermore, independent of the training group, a significant spatial pre-post difference was found in the event-related component P200 ( P = .04). PMID- 29569474 TI - S100A11 promotes TGF-beta1-induced epithelial-mesenchymal transition through SMAD2/3 signaling pathway in intrahepatic cholangiocarcinoma. AB - AIM: Our previous study found S100A11 was significantly raised in intrahepatic cholangiocarcinoma cells, but the relationship between S100A11 and intrahepatic cholangiocarcinoma remains unclear. METHODS: We investigated the effect of silencing S100A11 on TGF-beta1-induced epithelial-mesenchymal transition (EMT), cell migration and invasion. RESULTS: Our results demonstrated silencing S100A11 inhibited TGF-beta1-induced cell migration, invasion and EMT, expression of EMT markers E-cadherin, N-cadherin, beta-catenin, vimentin, Slug and Snail was reversed. Furthermore, TGF-beta1-induced p-SMAD2 and 3 were also inhibited due to low S100A11 expression. CONCLUSION: Our present study indicated that S100A11 promotes EMT through accumulation of TGF-beta1 expression, and TGF-beta1-induced upregulation of p-SMAD2 and 3. PMID- 29569475 TI - Association of monocyte to high-density lipoprotein cholesterol ratio with carotid artery intima-media thickness in patients with systemic lupus erythematosus. AB - AIM: The purpose of this study was to evaluate the relationship between monocyte to high-density lipoprotein cholesterol ratio (MHR) and carotid atherosclerostic plaque in patients with systemic lupus erythematosus (SLE). METHODS: A total of 214 SLE patients were divided into two groups according to the results of ultrasonic examination: carotid arterial atherosclerotic plaque groups and noncarotid arterial atherosclerosis groups. RESULTS: The values of monocyte to high-density lipoprotein-cholesterol ratio (MHR) increase in carotid arterial atherosclerotic plaque groups compared with noncarotid arterial atherosclerosis groups (0.32 +/- 0.18 vs 0.26 +/- 0.15; p = 0.015). There was a significant correlation between MHR and carotid artery intima-media thickness (r = 0.228; p = 0.001) in patients with SLE. CONCLUSION: Our study suggests that the values of MHR could be a marker to assess carotid artery intima-media thickness in patients with SLE. PMID- 29569476 TI - Surgery option in the management of delayed diplopia after radiation therapy for nasopharyngeal carcinoma. AB - PURPOSE: Radiation therapy is a standard treatment for nasopharyngeal carcinoma. Diplopia due to radiation damage to the sixth nerve significantly erodes the patient's quality of life. This study investigated the effectiveness of extraocular surgery in the treatment of delayed diplopia caused by radiation therapy. METHODS: A retrospective case series of 16 patients (7 men and 9 women) with delayed diplopia after radiation therapy for nasopharyngeal carcinoma was enrolled in the study. Unilateral lateral rectus resection was performed under topical anesthesia. Follow-up time was more than 12 months. Outcome measures were prism diopter and self-reported symptoms. RESULTS: All patients diagnosed with sixth nerve palsy reported elimination of symptoms on postoperative day 1 without complications. One patient required a second procedure due to recurrence of symptoms. At 12-month follow-up, no patient reported recurrence of symptoms. The absolute horizontal deviation significantly decreased from a preoperative value of 16 prism diopter to a value of 1.5 prism diopter postoperatively (p < 0.001). CONCLUSION: These results suggest that unilateral lateral rectus resection under topical anesthesia is an effective treatment for delayed diplopia after radiation therapy for nasopharyngeal carcinoma. A large randomized prospective study to confirm these findings is warranted. PMID- 29569477 TI - Optical coherence tomography angiography and choroidal neovascularization in multifocal choroiditis: A descriptive study. AB - PURPOSE: To analyze the ability of optical coherence tomography angiography to identify choroidal neovascularization in multifocal choroiditis and to describe active and inactive choroidal neovascularization findings. METHODS: Retrospective study of consecutive patients with multifocal choroiditis and choroidal neovascularization examined between January and November 2016. In addition to usual exams, optical coherence tomography angiography (AngioPlexTM CIRRUSTM HD OCT model 5000; Carl Zeiss Meditec, Inc., Dublin, CA, USA) images were assessed for morphological analysis: choroidal neovascularization size, choroidal neovascularization margin (well or poorly circumscribed), choroidal neovascularization shape (tangled or interlacing), choroidal neovascularization core (feeder vessel) and dark ring around the choroidal neovascularization. RESULTS: A total of 10 eyes were included. Optical coherence tomography angiography identified all choroidal neovascularization. Active choroidal neovascularization had well-circumscribed margins (67%), interlacing shape (83%), and a surrounding dark ring (83%). Inactive choroidal neovascularization had rather poorly circumscribed margins (75%), tangled shape, and "dead tree" appearance (50%) with less frequently a surrounding dark ring (50%). CONCLUSION: Optical coherence tomography angiography is adapted to confirm the diagnosis of choroidal neovascularization complicating multifocal choroiditis, but it is still insufficient to differentiate active and inactive lesions. PMID- 29569478 TI - Evaluation of hyaloid-retinal relationship during triamcinolone-assisted vitrectomy for primary rhegmatogenous retinal detachment. AB - AIMS: To determine hyaloid-retinal relationship in primary rhegmatogenous retinal detachment during vitreous surgery. METHODS: This is a prospective, interventional study of patients (n = 72) undergoing triamcinolone-assisted 25G vitreous surgery for primary rhegmatogenous retinal detachment. Hyaloid-retinal relationship was noted intraoperatively to identify regions and patterns of firm attachment and was classified into subgroups. Analysis was done to determine association between hyaloid-retinal relationship patterns and preoperative findings: posterior vitreous detachment, proliferative vitreoretinopathy, type of retinal tear, the presence of peripheral degenerations, and postoperative outcomes. RESULTS: Three patterns of hyaloid-retinal relationship were identified: type1 (complete absence of posterior vitreous detachment (21%)), type 2 (incomplete posterior vitreous detachment (47%)) and type 3 (complete posterior vitreous detachment (32%)). Posterior vitreous detachment in some form was present in 84% of the cases with retinal tears as the causative break but none of the cases with retinal holes (p < 0.001). None of the cases with vitreoretinal degeneration had complete posterior vitreous detachment (p = 0.001). 69% of proliferative vitreoretinopathy-C cases had type 1 hyaloid-retinal relationship as compared to 11% cases with no proliferative vitreoretinopathy (p < 0.001). Proliferative vitreoretinopathy-related anatomical failure was seen in 7.5%, and 80% of these eyes with recurrent RD had type 1 hyaloid-retinal relationship (p<0.001). Nearly half the patients diagnosed as complete posterior vitreous detachment preoperatively were found to have incomplete posterior vitreous detachment intraoperatively. CONCLUSIONS: Majority of the cases with rhegmatogenous retinal detachment have some form of strong vitreoretinal adhesion. Hyaloid-retinal relationship varies with types of retinal breaks, retinal degeneration, and proliferative vitreoretinopathy. Intraoperative hyaloid retinal relationship is frequently different from that assessed before surgery and the proposed classification may improve surgical decision making and prognostication. PMID- 29569479 TI - Comparing capsular bag performance of a hydrophilic and a hydrophobic intraocular lens: A randomised two-centre study. AB - PURPOSE:: To evaluate the capsular bag performance and posterior capsule opacification development of two intraocular lenses differing in material and design. METHODS:: This study included patients who were scheduled for cataract surgery and compared a hydrophilic intraocular lens (Super flex(r) intraocular lens; Rayner Surgical, Worthing, UK) with a hydrophobic intraocular lens (AcrySof(r) SA60AT; Alcon, Fort Worth, TX, USA). Follow-ups were performed 1 month and 2 years after cataract surgery, including a slit lamp examination and retroillumination images. RESULTS:: In total, 80 eyes of 80 patients were recruited. At the 1-month follow-up, 6 of 39 cases had a gap between the posterior lens capsule and intraocular lens (1 case in the hydrophilic intraocular lens group and 5 cases in the hydrophobic intraocular lens group; p = 0.348). Objective and subjective posterior capsule opacification scoring showed no statistically significant difference between both groups (p = 0.123). CONCLUSION:: Both intraocular lens showed a good capsular bag performance and a relatively low posterior capsule opacification development within the first 2 years after surgery.

AB - miRNA regulome is whole set of regulatory elements that regulate miRNA expression or are under control of miRNAs. Its understanding is vital for comprehension of miRNA functions. Classification of miRNA-related genetic variability is challenging because miRNA interact with different genomic elements and are studied at different omics levels. In the present study, miRNA-associated genetic variability is presented at three levels: miRNA genes and their upstream regulation, miRNA silencing machinery and miRNA targets. Several types of miRNA associated genetic variations are known, including short and structural polymorphisms and epimutations. Differential expression can also affect miRNA regulome function. Classification of miRNA-associated genetic variability presents a baseline for complementing sequence variant nomenclature, planning of experiments, protocols for multi-omics data integration and development of biomarkers. PMID- 29569483 TI - Pathological assessment of gastrointestinal biopsies from patients with idelalisib-associated diarrhea and colitis. AB - AIM: Idelalisib (IDELA) treatment is associated with diarrhea/colitis (incidence of ~15% grade >=3). We performed a retrospective analysis of gastrointestinal biopsies from 29 patients treated with IDELA across nine clinical trials. METHODS: A central core laboratory performed histopathologic review, immunohistochemistry, and droplet digital PCR viral studies. These results were correlated with tissue immune profiling data and morphologic features per modified Geboes score. RESULTS: Out of 29 eligible patients with abdominal pain or diarrhea, 24 (82.8%) had reported adverse event terms of diarrhea and/or colitis. Infectious pathogens were detected in 9/29 samples. Most biopsies presented with mixed/inflammatory infiltrates and contained increased numbers of FOXP3+ cells versus normal controls. CONCLUSION: This study revealed evidence of T-cell dysregulation and a substantial infectious component in association with IDELA-related diarrhea/colitis.

AB - Two new dihydrophenanthrenes, dendroinfundin A (1) and dendroinfundin B (2) were isolated from the whole plant of Dendrobium infundibulum, together with 7 known compounds (3-9). The structures of the new compounds (1 and 2) were established on the basis of their spectroscopic data. All of the isolates were evaluated for their alpha-glucosidase and pancreatic lipase inhibitory activities. Batatasin III (5) and dendrosinen B (9) showed strong alpha-glucosidase inhibitory activity. Dendrosinen B (9) also exhibited appreciable pancreatic lipase inhibitory effect. PMID- 29569486 TI - Pharmacoepigenetics in childhood acute lymphoblastic leukemia: involvement of miRNA polymorphisms in hepatotoxicity. AB - AIM: Hepatotoxicity is one of the most common drug-related toxicities during the treatment of childhood acute lymphoblastic leukemia (ALL). Many genes involved in liver-specific signaling pathways are tightly controlled by miRNAs, and miRNA function could be modulated by SNPs. As a consequence, we hypothesized that variants in miRNAs could be associated with drug-induced hepatotoxicity. METHODS: We analyzed 213 SNPs in 206 miRNAs in a cohort of 179 children with ALL homogeneously treated. RESULTS: rs2648841 in miR-1208 was the most significant SNP during consolidation phase after false discovery rate correction, probably through an effect on its target genes DHFR, MTR and MTHFR. CONCLUSION: These results point out the possible involvement of SNPs in miRNAs in toxicity to chemotherapy in children with ALL. PMID- 29569487 TI - Human and experimental toxicology of diquat poisoning: Toxicokinetics, mechanisms of toxicity, clinical features, and treatment. AB - Diquat (1,1'-ethylene-2,2'-bipyridinium ion; DQ) is a nonselective quick-acting herbicide, which is used as contact and preharvest desiccant to control terrestrial and aquatic vegetation. Several cases of human poisoning were reported worldwide mainly due to intentional ingestion of the liquid formulations. Its toxic potential results from its ability to produce reactive oxygen and nitrogen species through redox cycling processes that can lead to oxidative stress and potentially cell death. Kidney is the main target organ due to DQ toxicokinetics and redox cycling. There is no antidote against DQ intoxications, and the efficacy of treatments currently applied is still unsatisfactory. The aim of this work was to review the most relevant human and experimental findings related to DQ, characterizing its chemistry, activity as herbicide, mechanisms of toxicity, consequences of poisoning, and potential therapeutic approaches taking into account previous experience in developing antidotes for paraquat, a more toxic bipyridinium herbicide.

AB - In addition to muscle weakness, amyotrophic lateral sclerosis (ALS) is associated with an increased incidence of skeletal fractures. The SOD1G93A mouse model recapitulates many features of human ALS. These mice also exhibit decreased bone mass. However, the functional, or biomechanical, behavior of the skeleton in SOD1G93A mice has not been investigated. To do so, we examined skeletal phenotypes in end-stage (16-week-old) SOD1G93A female mice and healthy littermate female controls (N = 9-10/group). Outcomes included trabecular and cortical bone microarchitecture by microcomputed tomography; stiffness and strength via three point bending; resistance to crack growth by fracture toughness testing; and cortical bone matrix properties via cyclic reference point indentation. SOD1G93A mice had similar bone size, but significantly lower trabecular bone mass (-54%), thinner trabeculae (-41%) and decreased cortical bone thickness (-17%) and cortical area (-18%) compared to control mice (all p < 0.01). In line with these bone mass and microstructure deficits, SOD1G93A mice had significantly lower femoral bending stiffness (-27%) and failure moment (-41%), along with decreased fracture toughness (-18%) (all p < 0.001). This is the first study to demonstrate functional deficits in the skeleton of end-stage ALS mice, and imply multiple mechanisms for increased skeletal fragility and fracture risk in patients in ALS. Importantly, our results provide strong rationale for interventions to reduce fracture risk in ALS patients with advanced disease. PMID- 29569490 TI - The ambulances at the top of the cliff.

PMID- 29569492 TI - A Bayesian network meta-analysis of PCSK9 inhibitors, statins and ezetimibe with or without statins for cardiovascular outcomes. AB - Background The comparative effects of statins, ezetimibe with or without statins and proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors remain unassessed. Design Bayesian network meta-analysis was conducted to compare treatment groups. Methods Thirty-nine randomized controlled trials were selected using MEDLINE, EMBASE, and CENTRAL (inception - September 2017). Results In network meta-analysis of 189,116 patients, PCSK9 inhibitors were ranked as the best treatment for prevention of major adverse cardiovascular events (Surface Under Cumulative Ranking Curve (SUCRA), 85%), myocardial infarction (SUCRA, 84%) and stroke (SUCRA, 80%). PCSK9 inhibitors reduced the risk of major adverse cardiovascular events compared with ezetimibe + statin (odds ratio (OR): 0.72; 95% credible interval (CrI), 0.55-0.95; Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria: moderate), statin (OR: 0.78; 95% CrI: 0.62-0.97; GRADE: moderate) and placebo (OR: 0.63; 95% CrI: 0.49-0.79; GRADE: high). The PCSK9 inhibitors were consistently superior to groups for major adverse cardiovascular event reduction in secondary prevention trials (SUCRA, 95%). Statins had the highest probability of having lowest rates of all-cause mortality (SUCRA, 82%) and cardiovascular mortality (SUCRA, 84%). Compared with placebo, statins reduced the risk of all-cause mortality (OR: 0.88; 95% CrI: 0.83 0.94; GRADE: moderate) and cardiovascular mortality (OR: 0.84; 95% CrI: 0.77 0.90; GRADE: high). For cardiovascular mortality, PCSK9 inhibitors were ranked as the second best treatment (SUCRA, 78%) followed by ezetimibe + statin (SUCRA, 50%). Conclusion PCSK9 inhibitors were ranked as the most effective treatment for reducing major adverse cardiovascular events, myocardial infarction and stroke, without having major safety concerns. Statins were ranked as the most effective therapy for reducing mortality. PMID- 29569493 TI - How to design carbohydrate diet regimens for heart disease patients.

PMID- 29569494 TI - N-terminal fraction of pro-B-type natriuretic peptide versus clinical risk scores for prognostic stratification in chronic systolic heart failure. AB - Background The Seattle heart failure model or the cardiac and comorbid conditions (3C-HF) scores may help define patient risk in heart failure. Direct comparisons between them or versus N-terminal fraction of pro-B-type natriuretic peptide (NT proBNP) have never been performed. Methods Data from consecutive patients with stable systolic heart failure and 3C-HF data were examined. A subgroup of patients had the Seattle heart failure model data available. The endpoints were one year all-cause or cardiovascular death. Results The population included 2023 patients, aged 68 +/- 12 years, 75% were men. At the one year time-point, 198 deaths were recorded (10%), 124 of them (63%) from cardiovascular causes. While areas under the curve were not significantly different, NT-proBNP displayed better reclassification capability than the 3C-HF score for the prediction of one year all-cause and cardiovascular death. Adding NT-proBNP to the 3C-HF score resulted in a significant improvement in risk prediction. Among patients with Seattle heart failure model data available ( n = 798), the area under the curve values for all-cause and cardiovascular death were similar for the Seattle heart failure model score (0.790 and 0.820), NT-proBNP (0.783 and 0.803), and the 3C-HF score (0.770 and 0.800). The combination of the 3C-HF score and NT-proBNP displayed a similar prognostic performance to the Seattle heart failure model score for both endpoints. Adding NT-proBNP to the Seattle heart failure model score performed better than the Seattle heart failure model alone in terms of reclassification, but not discrimination. Conclusions Among systolic heart failure patients, NT-proBNP levels had better reclassification capability for all cause and cardiovascular death than the 3C-HF score. The inclusion of NT-proBNP to the 3C-HF and Seattle heart failure model score resulted in significantly better risk stratification. PMID- 29569496 TI - Development of carbazole-bearing pyridopyrimidine-substituted urea/thiourea as polyphenol oxidase inhibitors: synthesis, biochemistry, and theoretical studies. AB - Polyphenol oxidase (Tyrosinase, PPO) has received considerable attention, since it is the key enzyme in melanin biosynthesis. In this study, we investigated prepared novel carbazole-containing pyridopyrimidine-substituted with urea and thiourea derivatives and their PPO activities on the diphenolase activity of banana tyrosinase. The structures of the compounds synthesized were confirmed by 1 H NMR, 13 C NMR, FTIR and elemental analysis. PPO enzyme was purified from banana on an affinity gel comprised of Sepharose 4B-L-tyrosine-p-amino benzoic acid. For evaluating the enzyme activity, the synthesised compounds were subjected to tyrosinase inhibition assay using catechol as substrate. While some of the compounds (6, 7, 8f, 8h, 8i, 8j) showed enzyme inhibitor effect, some of them (8a, 8b, 8c, 8d, 8e, 8g, 8k) activated the PPO enzyme activity. Gaussian software was used for the molecular calculations to explain the results for the prepared compounds. PMID- 29569497 TI - Racial and ethnic disparities in stroke outcomes: a scoping review of post-stroke disability assessment tools. AB - PURPOSE: To identify how post-stroke disability outcomes are assessed in studies that examine racial/ethnic disparities and to map the identified assessment content to the International Classification of Functioning, Disability, and Health (ICF) across the time course of stroke recovery. METHODS: We conducted a scoping review of the literature. Articles published between January 2001 and July 2017 were identified through Scopus, PubMed, CINAHL, and PsycINFO according to predefined inclusion and exclusion criteria. RESULTS: We identified 1791 articles through database and hand-searching strategies. Of the articles, 194 met inclusion criteria for full-text review, and 41 met inclusion criteria for study inclusion. The included studies used a variety of outcome measures encompassing domains within the ICF: body functions, activities, participation, and contextual factors across the time course of stroke recovery. We discovered disproportionate representation among racial/ethnic groups in the post-stroke disability disparities literature. CONCLUSIONS: A wide variety of assessments are used to examine disparities in post-stroke disability across the time course of stroke recovery. Several studies have identified disparities through a variety of assessments; however, substantial problems abound from the assessments used including inconsistent use of assessments, lacking evidence on the validity of assessments among racial/ethnic groups, and inadequate representation among all racial/ethnic populations comprising the US. Implications for Rehabilitation An enhanced understanding of racial/ethnic disparities in post-stroke disability outcomes is inherently important among rehabilitation practitioners who frequently engage with racial/ethnic minority populations across the time course of stroke recovery. Clinicians should carefully consider the psychometric properties of assessment tools to counter potential racial bias. Clinicians should be aware that many assessments used in stroke rehabilitation lack cultural sensitivity and could result in inaccurate assessment findings. PMID- 29569498 TI - Educating children and adolescents about vaccines: a review of current literature. AB - INTRODUCTION: Until recently, research on vaccine hesitancy has focused primarily on parent populations. Although adolescent knowledge and views are gaining momentum within the literature, particularly with regards to the human papillomavirus and influenza, children remain a virtually unstudied population with regards to vaccine hesitancy. Areas Covered: This review focuses on the lack of literature in this area and argues for more vaccine hesitancy research involving child and adolescent populations. It also outlines special issues to consider when framing health promotion messages for children and adolescents. Finally, we explore the use of new and existing technologies as delivery mechanisms for education on vaccines and immunizations in populations of children and adolescents. Expert Commentary: Children undergo cognitive development and experiences with vaccines (e.g. pain or education) have the potential to create future attitudes toward vaccines. This can influence future vaccine behaviour, including their participation in decision-making around adolescent vaccines, their decisions to vaccinate themselves when they are adults, and their decisions to vaccinate their own children. Interventions aimed at children, such as education, can create positive attitudes toward vaccines. These can also potentially influence parental attitudes toward vaccines as children convey this knowledge to them. Both of these impacts require further study. PMID- 29569499 TI - Topically administered hyaluronic acid in the upper airway: A narrative review. AB - Hyaluronic acid plays a role in controlling inflammatory airway processes and mucociliary clearance, and it is also involved in tissue healing and remodelling. Some studies have tested the effectiveness of topically administered hyaluronic acid in patients with upper airway diseases with positive preliminary results. This article describes the use of topically administered hyaluronic acid in patients with otolaryngological disorders. Pertinent studies published between January 2000 and October 2016 were selected by means of a MEDLINE search using the following terms: 'hyaluronic acid' and 'otolaryngology', 'otitis', 'pharyngitis', 'tonsillitis', 'rhinitis', 'rhinosinusitis' and 'nose'. Twelve of the 19 initially identified papers were selected, corresponding to 902 patients as a whole. There is some evidence that topically administered hyaluronic acid is effective or moderately effective in different otolaryngological conditions, as it improves the global subjective and clinical status of patients with inflammation of the nasopharyngeal and oto-tubaric complex, those with rhinitis or rhinosinusitis and those who have undergone nasal and sinonasal surgery. However, these findings should be viewed cautiously as they are based on a limited number of studies, some of which were probably under-powered because of their small patient samples. PMID- 29569500 TI - Mechanisms of action and clinical use of specific reversal agents for non-vitamin K antagonist oral anticoagulants. AB - OBJECTIVES: With a steadily growing number of patients with non-valvular atrial fibrillation, anticoagulation use increases. Anticoagulation therapy is associated with increased risk of serious bleeding and an increased complexity in management of patients in need for urgent surgery. We wanted to assess the magnitude of this challenge as well as review current and potential future clinical management strategies. DESIGN: A review of the literature on the magnitude of patients using antigoaculants in potential need for acute restoration of hemostasis was conducted, as well as current status of reversal agents for non-vitamin K antagonist oral anticoagulants (NOACs). Additionally, a case illustration of its use is presented. RESULTS: Two main groups of patients may need acute restoration of hemostasis, those in need of acute surgery or acute invasive procedures, ~ 2% of patients annually, and those with serious and critical hemorrhage, ~1.5% annually. One specific reversal agent is available on the market (idarucizumab) and two (andexanet alfa, ciraparantag) are in clinical development. Idarucizumab is a specific antidote for the thrombin inhibitor dabigatran while andexanet alfa is factor Xa inhibitor class-specific currently in late-stage development. Ciraparantag is a universal reversal agent in early phase development. These agents can facilitate effective management of bleeding or bleeding risk, as illustrated in a patient on dabigatran in urgent need for a pacemaker. CONCLUSIONS: Amongst patients using anticoagulants, around 3.5%, could be in need of immediate restoration of hemostasis annually. The availability and use of specific reversal agents for NOACs could be crucial for the clinical outcomes.

AB - INTRODUCTION: The staging of breast carcinoma is mainly dependent on tumor size and lymph node status. Small increments in tumor size upstage the patient. An accurate determination of the tumor size is therefore critically important. Although the final staging is based on microscopic size, pathologists rely on gross measurements in a considerable number of cases. METHODS: We investigated the concordance between gross and microscopic measurements of breast carcinoma as well as factors affecting this concordance. This study is a retrospective review of surgical pathology reports of invasive breast carcinomas. Data were collected for 411 cases. Concordance was defined as a size difference within +/-2 mm. RESULTS: Gross and microscopic sizes were identical in 33.1% of cases. Gross and microscopic size difference was within +/-2 mm in 56% of cases. Despite the size difference, stage classification ended up being the same in 68.6% of cases. Tumor stage was over estimated by gross measurement in 17.0% of cases and underestimated in 14.4% of cases. The concordance was significantly higher for those tumors in which final pathologic tumor (pT) size was greater than 2 cm (>=pT2) as compared with those less than or equal to 2 cm (<=pT1; P < .0001). A higher proportion of mastectomy specimens (61.4%) were concordant as compared with lumpectomy specimens (52.1%). CONCLUSION: Gross and microscopic tumor sizes were concordant in 56% of cases. Stage classification based on gross and microscopic tumor size was different in nearly one third (31.4%) of cases. Gross tumor size is critically important in accurate staging at least in cases where tumor size cannot be confirmed microscopically. PMID- 29569501 TI - Being in control of Parkinson's disease: A qualitative study of community dwelling patients' coping with changes in care. AB - BACKGROUND: Chronically ill patients have to cope with transfers in the level or setting of care. Patients with prevalent disorders such as diabetes mellitus can be supported by their general practitioner (GP) when experiencing such care changes, as the GP already offers them disease-specific care. For community dwelling patients with low-prevalent diseases such as Parkinson's disease (PD) - for which disease-specific care is provided by medical specialists - tailoring support to handle care changes requires more insight into patients' coping. OBJECTIVES: To explore PD patients' coping with care changes. METHODS: A qualitative interview study was performed in 2013-2015 with a purposive sample of 16 community-dwelling PD patients in the Netherlands. A research assistant visited patients every month to explore if they had experienced a care change. If so, patients were interviewed face-to-face. An inductive approach to comparative content analysis was used. RESULTS: Patients encountered a variety of care changes such as changes in the level of unpaid care, the purchase of tools, modification of pharmacotherapy or admission to hospital. Being able to anticipate, initiate and independently handle care changes contributes to patients' sense of control and acceptance of the post-change situation. Patients, who commenced care changes themselves, had more realistic expectations of it. CONCLUSION: Community-dwelling PD patients seem to be able to cope with the care changes they face. Offering education to facilitate their anticipation and initiation of changes in care and their ability to act independently, can contribute to patients' wellbeing. GPs can play a role in this. PMID- 29569504 TI - C1-esterase inhibitor (Cinryze(r)) use in the treatment of pediatric hereditary angioedema. AB - Hereditary angioedema (HAE) is a rare genetic disease resulting in unpredictable and potentially life-threatening subcutaneous and submucosal attacks mediated by the vasoactive peptide, bradykinin. HAE often presents within the first or second decade of life, with attacks increasing in both frequency and severity over time. First-line therapies exert their action by replacing C1 inhibitor (C1-INH) or via blocking the production or function of bradykinin. Cinryze(r) is a nanofiltered C1-INH, approved in Europe for the acute treatment, preprocedure prevention and routine prophylaxis of HAE attacks, and for routine prophylaxis of attacks in the USA. Of the current C1-INH preparations available, Cinryze shows particular promise in the safe and effective treatment and prophylaxis of HAE attacks in pediatric age patients. PMID- 29569505 TI - Risk factors associated with complications/sequelae of acute and subacute haematogenous osteomyelitis: an Italian multicenter study. AB - BACKGROUND: Acute/subacute haematogenous osteomyelitis (AHOM/SAHOM) are potentially devastating diseases. Updated information about the epidemiology, management and outcome of AHOM/SAHOM is needed to minimize the risk of complications and sequelae. METHODS: A multicenter study was performed to evaluate retrospectively the management and outcome of AHOM/SAHOM in Italy. Data from children aged >1 month, and hospitalized between 2010 and 2016, in 19 pediatric centers, were analyzed. RESULTS: 300 children with AHOM and 98 with SAHOM were included. Median age was 6.0 years (IQR: 2.0-11.0). No clinical difference was observed with the exception of fever at onset (63.0% vs. 42.9%; P < 0.0001), and a more common spinal involvement in SAHOM (6.7% vs 20.4%; P < 0.001). Fifty-Eight Staphylococcus aureus strains were isolated; 5 (8.6%) were MRSA. No Kingella kingae infection was documented. No different risk for complication/sequela was observed between AHOM and SAHOM (38.3% vs. 34.7%; OR:0.85; 95%CI: 0.53-1.38; P = 0.518). Duration and type of antibiotic therapy were not associated with risk of complication/sequelae. CONCLUSION: AHOM and SAHOM displayed some differences, however occurrence and risk factors for complications and sequelae are similar, and the same empiric treatment might be recommended.

PMID- 29569508 TI - Nanoparticle-based CpG-oligonucleotide therapy for treating allergic asthma. AB - Allergic asthma is becoming increasingly prevalent in the developed world, and many common allergens are capable of inducing allergic asthma responses, particularly in atopic individuals. Unmethylated CpG-oligonucleotide (ODN) therapy can shift the immune response to mitigate these allergic responses. Therapeutic and prophylactic delivery of soluble CpG-ODN in preclinical studies has shown promise in treating existing asthma and preventing allergic responses upon subsequent allergen exposure, respectively. However, when CpG-ODN is coupled with nanoparticles or self assembled into nanostructures, improved efficacy of CpG-ODN treatment for several common allergens is observed in preclinical studies and clinical trials. Here we discuss the role of CpG-ODN in treating allergic asthma and how nanoparticle-based delivery can further enhance its therapeutic properties. PMID- 29569506 TI - Impact of allergen immunotherapy in allergic asthma. AB - Although traditional pharmacological approaches improve outcomes in disease management for allergic asthma, these fail to modify the underlying immune responses. Allergen immunotherapy remains the only etiological therapy for the treatment of respiratory allergies for which clinical efficacy has been demonstrated through several well-controlled studies. In this review, we examine evidence from the past 5 years regarding the impact of allergen immunotherapy on allergic asthma to inform practitioners and stimulate further discussion and research. PMID- 29569509 TI - The future impacts of non-targeted effects. AB - Ionizing radiation was traditionally thought to exert its detrimental effects through interaction with sensitive cellular targets, nuclear DNA being of most importance. This theory has since merged with a more recently described radiation response called non-targeted effects (NTE). This review will briefly look at the various types of NTE and the potential implications they may have for radiobiology research and its applications. The most well-known NTE are genomic instability (GI) and bystander effects (BE). Other NTE include abscopal effects, which are similar to bystander effects but are generally based in a clinical environment with immune involvement as the defining feature. Currently, our understanding of NTE is limited to certain signaling pathways/molecules, and as yet there is no theory that describes or can accurately predict the occurrence or outcome of these NTE. There are numerous groups investigating these processes in vitro and in vivo, and thus steady progress is being made. Developing a deeper understanding of NTE has potential impacts for therapy and diagnosis, safer occupational exposures, space flight and our general understanding of radiation biology. PMID- 29569510 TI - Consequences of B-cell-depleting therapy: hypogammaglobulinemia and impaired B cell reconstitution. AB - Rituximab is a chimeric monoclonal antibody used to treat hematologic and autoimmune diseases by depleting CD20-expressing B cells. Patients may develop hypogammaglobulinemia following treatment, with some demonstrating failure of B cell recovery. The true frequency of hypogammaglobulinemia and/or impaired B-cell reconstitution post rituximab is unknown due to the lack of prospective studies in different patient cohorts. The clinical significance remains controversial; some patients have recurrent infections while others are relatively asymptomatic. The aim of this review is to describe the prevalence of hypogammaglobulinemia and the associated risk for developing severe infection, in patients with differing underlying clinical conditions treated with rituximab. This may facilitate classification and prognostication of patients who develop these conditions and identify patients who may be at high risk of developing these complications, including those who may benefit from immunoglobulin replacement therapy. PMID- 29569511 TI - Radioimmunotherapy as the first line of treatment in non-Hodgkin lymphoma. AB - Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy. The estimated deaths and new cases of NHL in the USA in 2018 have reached 19,910 and 74,680, respectively, with 5-year survival rate of 71%. Therapeutic interventions for NHL consist of chemotherapy, radiation therapy and immunotherapy. Radioimmunotherapy (RIT) is a potential alternative treatment for NHL that is currently used in different lines of treatment. Studies show that nuclear medicine physicians and radiation oncologists are not yet certain about the proper line for administration of RIT. Herein, we have reviewed the efficiency and toxicity of RIT as the first line of treatment, and discussed potential novel indications, and strategies such as modifying induction therapy and using rituximab maintenance to optimize the efficiency of RIT as the first line of treatment. Our review indicates that it is more logical to postpone conventional therapies to the second or third lines of treatment instead of RIT. PMID- 29569512 TI - Construction of a recombinant B-cell epitope vaccine based on a Der p1-derived hypoallergen: a bioinformatics approach. AB - AIM: House dust mite (HDM) allergens are important elicitors of IgE-mediated allergies. This study was aimed at constructing and characterizing a recombinant fusion protein, DpTTDp, which was based on carrier-bound Der p 1-derived peptides for HDM allergen immunotherapy. METHODS: Using the Immune Epitope Database (IEDB), we identified from Der p 1, a 34-mer hypoallergenic peptide. Two copies of the hypoallergen were then fused to a partial fragment of a tetanus toxoid molecule's N-and C terminus and expressed in Escherichia coli. After purification to homogeneity, the protein was evaluated for allergenicity and its ability to induce blocking antibodies upon immunization. RESULTS: Upon immunization of mice, DpTTDp induced high levels of protective IgG-antibodies that blocked allergic patients' IgE reactivity to HDM. In addition, DpTTDp lacked relevant IgE reactivity, induced low T-cell proliferation and IFN-gamma in peripheral blood mononuclear cells of HDM-allergic patients' sera. CONCLUSION: The protein represents a promising HDM-allergy immunotherapy candidate vaccine. PMID- 29569513 TI - A Role for the Frontal Aslant Tract in Speech Planning: A Neurosurgical Case Study. AB - Frontal and temporal white matter pathways play key roles in language processing, but the specific computations supported by different tracts remain a matter of study. A role in speech planning has been proposed for a recently described pathway, the frontal aslant tract (FAT), which connects the posterior inferior frontal gyrus to the pre-SMA. Here, we use longitudinal functional and structural MRI and behavioral testing to evaluate the behavioral consequences of a lesion to the left FAT that was incurred during surgical resection of a frontal glioma in a 60-year-old woman, Patient AF. The pattern of performance in AF is compared, using the same measures, with that in a 37-year-old individual who underwent a left anterior temporal resection and hippocampectomy (Patient AG). AF and AG were both cognitively intact preoperatively but exhibited specific and doubly dissociable behavioral deficits postoperatively: AF had dysfluent speech but no word finding difficulty, whereas AG had word finding difficulty but otherwise fluent speech. Probabilistic tractography showed that the left FAT was lesioned postoperatively in AF (but not AG) whereas the inferior longitudinal fasciculus was lesioned in AG (but not AF). Those structural changes were supported by corresponding changes in functional connectivity to the posterior inferior frontal gyrus: decreased functional connectivity postoperatively between the posterior inferior frontal gyrus and pre-SMA in AF (but not AG) and decreased functional connectivity between the posterior inferior frontal gyrus and the middle temporal gyrus in AG (but not AF). We suggest from these findings that the left FAT serves as a key communicative link between sentence planning and lexical access processes. PMID- 29569514 TI - Expression levels of selected genes can predict individual rheumatoid arthritis patient response to tumor necrosis factor alpha blocker treatment. AB - OBJECTIVES: Rheumatoid arthritis (RA) patients have many therapeutic options; however, tools to predict individual patient response are limited. The Genefron personal diagnostic kit, developed by analyzing large datasets, utilizes selected interferon stimulated gene expressions to predict treatment response. This study evaluates the kit's prediction accuracy of individual RA patients' response to tumor necrosis alpha (TNFalpha) blockers. METHODS: A retrospective analysis was performed on RA patients reported in published datasets. A prospective analysis assessed RA patients, before and 3 months after starting a TNFalpha blocker. Clinical response was evaluated according to EULAR response criteria. Blood samples were obtained before starting treatment and were analyzed utilizing the kit which measures expression levels of selected genes by quantitative real time polymerase chain reaction (PCR). ROC analysis was applied to the published datasets and the prospective data. RESULTS: The Genefron kit analysis of retrospective data predicted the response to a TNFalpha blocker in 53 of 61 RA patients (86.8% accuracy). In the prospective analysis, the kit predicted the response in 16 of 18 patients (89% accuracy) achieving a EULAR moderate response, and in 15 of 18 patients achieving a EULAR good response (83.3% accuracy). ROC analysis applied to the two published datasets yielded an AUC of 0.89. ROC analysis applied to the prospective data yielded an AUC of 0.83 (sensitivity - 100%, specificity - 75%) The statistical power obtained in the prospective study was .9. CONCLUSION: The diagnostic kit predicted the response to TNFalpha blockers in a high percentage of patients assessed retrospectively or prospectively. This personal kit may guide selection of a suitable biological drug for the individual RA patient. PMID- 29569515 TI - Prevalence of salivary human herpesviruses in pediatric multiple sclerosis cases and controls. AB - BACKGROUND: Multiple sclerosis (MS) is a multifactorial disease of unknown origin. The current paradigm is that disease develops in genetically susceptible individuals, influenced by environmental factors. Epstein-Barr virus (EBV) and human herpesvirus 6 (HHV-6) have particularly strong associations with the disease. Both viruses are typically acquired during childhood, decades before MS presents. However, in patients with pediatric MS, the temporal window between viral acquisition and disease onset is shortened, which may provide insights into the association of herpesviruses with MS. OBJECTIVE: To compare the frequency of EBV and HHV-6 in the saliva of a cohort of pediatric MS patients and age-matched controls. METHODS: The study enrolled 32 pediatric MS patients and 42 controls and evaluated saliva for HHV-6 u57 and EBV lmp-1 amplification by droplet digital polymerase chain reaction (ddPCR). RESULTS: Pediatric MS patients did not differ from controls in the frequency or magnitude of salivary viral shedding. During the assessment of EBV positivity, distinct profiles emerged that correlated with target amplicon mutations. CONCLUSIONS: None of these mutations were evident in EBV-positive samples from pediatric MS patients, whereas they were present in pediatric controls, in addition to MS and control adults, suggesting differential host-immune control of EBV in this pediatric MS cohort. PMID- 29569516 TI - Intravascular Large B-Cell Lymphoma Within a Thyroid Nodule: A Diagnostic Pitfall. AB - Intravascular large B-cell lymphoma (IVLBCL) is a subtype of diffuse large B-cell lymphoma, where the neoplastic lymphoid proliferation resides predominantly within the lumens of blood vessels but with no or few circulating neoplastic cells in the peripheral circulation. Focal or subtle involvement in some cases can cause the diagnosis to be misinterpreted or even overlooked, delaying the initiation of appropriate treatment. Our report focuses on a 78-year-old woman with a progressively enlarging thyroid mass, verified by ultrasound. She underwent a hemithyroidectomy, and microscopic evaluation demonstrated nodular thyroid parenchyma with atypical large cells in an intravascular distribution pattern identified on high magnification. Thorough evaluation showed that the large intravascular cells were positive CD20, PAX-5, and Ki-67 by immunoperoxidase staining, which lead to the diagnosis of IVLBCL. This case emphasizes the subtle appearance of IVLBCL, which may be missed on low-power light microscopy, and the need for careful evaluation of thyroid resection specimens. PMID- 29569517 TI - Discrepancies between crystallized and fluid ability are associated with frequency of social and physical engagement in community dwelling older adults. AB - OBJECTIVE: Age differences have been noted in the discrepancies between crystallized and fluid ability (Gc-Gf). Larger Gc-Gf discrepancies have also been shown to be associated with Alzheimer's disease biomarkers and clinical severity. However, little is known regarding the relationship between Gc-Gf discrepancies in normal aging and functional outcomes. The aim of the present study was to examine this. METHOD: Data from 104 adults (Mage = 71.70 years, SD = 9.016) were included in the present study. Measures from the NIH toolbox were used to form the discrepancy scores. Physical, cognitive, and social activities were identified using the Community Healthy Activities Model Program for Seniors activity questionnaire. Linear regression analyses, controlling for age, education, gender, health, and depressive symptoms, were used to examine the association between social, cognitive, and physical activities on Gc-Gf discrepancies. RESULTS: Results showed that social and physical activity were significantly associated with greater discrepancies between crystallized and fluid ability, independent of covariates. There was no association between cognitive activity and Gc-Gf discrepancies. CONCLUSIONS: Larger discrepancies between crystallized and fluid ability are related to frequency of social and physical activity. The findings support previous research that discrepancy scores may serve as a marker of cognitive decline. In more highly educated older individuals, Gc-Gf discrepancies may be a more accurate indicator of actual cognitive status. PMID- 29569518 TI - Do selective serotonin reuptake inhibitors increase the risk of bleeding or mortality following coronary artery bypass graft surgery? A meta-analysis of observational studies. AB - INTRODUCTION: Depressive illness has a high prevalence in patients undergoing coronary artery bypass graft surgery (CABG). The first line treatment for depression are selective serotonin reuptake inhibitors (SSRIs) which inhibit serotonin reuptake in the presynaptic neuronal membrane and uptake by platelets, inhibiting subsequent serotonin-mediated platelet activation. This presents a theoretically increased risk of bleeding and subsequent postoperative mortality. This review aims to investigate the effects of SSRIs on postoperative bleeding, defined as the need for transfusions and re-operation for bleeding, as well as 30 day mortality in patients undergoing CABG. METHOD: Four hundred and thirty-seven papers were screened with seven meeting the full inclusion criteria. RESULTS: Meta-analysis demonstrated that SSRI use increased the risk of red blood cell transfusion (odds ratio (OR) = 1.15; 95% confidence interval (CI): 1.06-1.26), but resulted in no difference in the rate of re-operation for bleeding (OR = 1.07; 95% CI: 0.66-1.74). SSRI use had no effect on the rates of platelet (OR = 0.93; 95% CI: 0.79-1.09) or fresh frozen plasma (OR = 0.96; 95% CI: 0.74-1.24) transfusion nor on the mortality rate (OR =1.03; 95 CI: 0.90-1.17). CONCLUSION: This review demonstrates that SSRIs are largely safe in cardiac surgery as no increase in mortality was observed. However, there is a significantly raised chance of red blood cell transfusion. The heterogeneous nature of the current evidence base highlights the need for further research into SSRIs and whether any effect on patient outcomes in cardiac surgery occurs.

AB - In traditional Chinese culture, death was sensitive and mentioning it was sacrilegious and to be avoided. Many Chinese families object to telling the patient a "bad" diagnosis or prognosis, which may hinder the chance in advance care planning (ACP) discussion. While death remains an inevitable consequence of being born, as such, it is important that human beings recognize its inevitability and plan ahead of a good death. Advance care planning enables patients to assert their care preferences in the event that they are unable to make their own medical decisions. In China, a rapidly aging demographic presents additional challenges to quality end-of-life care. The adoption of palliative care in China has been slow, with a curative approach dominating health-care strategies. In this article, we would summarize China's current situation in population aging, palliative care development, and Chinese cultural values on death and dying and review the advance directive and end-of-life care preferences among Chinese elderly patients. Current literature recommended the use of indirect communication approaches to determine Chinese seniors' readiness. In individual practice, using depersonalized communication strategies to initiate the discussion was recommended to determine older Chinese seniors' readiness. PMID- 29569521 TI - Impact of SCBA size and fatigue from different firefighting work cycles on firefighter gait. AB - Risk of slips, trips and falls in firefighters maybe influenced by the firefighter's equipment and duration of firefighting. This study examined the impact of a four self-contained breathing apparatus (SCBA) three SCBA of increasing size and a prototype design and three work cycles one bout (1B), two bouts with a five-minute break (2B) and two bouts back-to-back (BB) on gait in 30 firefighters. Five gait parameters (double support time, single support time, stride length, step width and stride velocity) were examined pre- and post firefighting activity. The two largest SCBA resulted in longer double support times relative to the smallest SCBA. Multiple bouts of firefighting activity resulted in increased single and double support time and decreased stride length, step width and stride velocity. These results suggest that with larger SCBA or longer durations of activity, firefighters may adopt more conservative gait patterns to minimise fall risk. Practitioner Summary: The effects of four self contained breathing apparatus (SCBA) and three work cycles on five gait parameters were examined pre- and post-firefighting activity. Both SCBA size and work cycle affected gait. The two largest SCBA resulted in longer double support times. Multiple bouts of activity resulted in more conservative gait patterns. PMID- 29569522 TI - Can athletes' reports of self-regulated learning distinguish deliberate practice from physical preparation activity? AB - Sustained persistence in deliberate practice (DP) could be aided by engagement in adaptive motivational and metacognitive types of self-regulated learning (SRL) processes. We examined relationships between SRL and each of DP and physical preparation (PP; e.g., cross-training) in supervised, unsupervised, social and non-social practice contexts. 272 individual-sport athletes (from city to international level; M sport activity = 13.54 hrs/wk; 200 males, ages 18-35) completed the Self-Regulation of Learning Self-Report Scale and reported weekly DP and PP amounts. We found contrasting results depending on specific SRL processes. Self-monitoring was related to DP (total, supervised, social conditions) but inversely related to PP. Effort was inversely related to supervised DP but positively associated with PP. Planning was associated with DP, and reflection and self-efficacy related to PP. We discuss the contrast between DP and PP, highlighting differences in the nature of these practice activities, and self-monitoring as a key SRL process for DP. PMID- 29569523 TI - Reply to Behrman.

AB - Objective This study aimed to investigate the incidence and related risk factors of cerebral microbleeds (CMBs) in young and middle-aged patients with hypertension. Methods The study included 232 young and middle-aged (18-59 years old) patients with hypertension from September 2014 to December 2016 in the Department of Neurology, Affiliated Hospital of Guizhou Medical University, China. The data were recorded which included demographics, vascular risk factors, medication history, and imaging data of patients. CMBs were evaluated based on the microbleeds anatomical rating scale. Results Of the enrolled participants, 115 were CMB positive, accounting for 49.6%. CMBs were more prone to occur in deep regions than in others (39.13%). Multiple cerebral microbleeds were associated with white matter hyperintensities(WMH), dyslipidemia, hyperhomocysteine, and uric acid. Moreover, WMH, dyslipidemia, ever smoker, antiplatelets use, and hyperhomocysteine were found to be risk factors for deep or infratentorial CMBs in young and middle-aged patients with hypertension. However, the lobar CMBs only had an independent correlation with dyslipidemia in these participants. Conclusions The incidence of CMBs in patients with hypertension was relatively high. It mostly occurred in a deep or infratentorial area with more vascular-associated risk factors. However, in patients with lobar CMBs, factors associated with lipid metabolism, such as amyloid deposition and unidentified genotype variation, may be crucial. Screening and regular follow-ups of CMBs by Susceptibility Weighted Imaging and active prevention in young and middle-aged patients with hypertension have clinical significance for timely understanding and predicting the occurrence and development of related cerebrovascular disease events. PMID- 29569525 TI - Prevalence and trends of overweight and obesity in older adults from 10 European countries from 2005 to 2013. AB - AIMS: Overweight and obesity are clinical public-health concerns worldwide. Amongst older adults, the prevalence of overweight and obesity is considered high. The purpose of this study was to provide current data regarding the prevalence and trends of overweight and obesity of adults from 2005 to 2013 in 10 European countries. METHODS: The data used in the present study were derived from the first, second, fourth and fifth waves of the Survey of Health, Ageing and Retirement in Europe. The present study includes individuals aged ?50 years from 10 European countries. Body mass index (BMI) was calculated from self-reported height and weight (kg/m2). RESULTS: The general prevalence of overweight (BMI ?25 kg/m2) was slightly above 60% and remained stable between 2005 (60.1%, 95% confidence interval (CI): 59.3-60.9%) and 2013 (60.3%, 95% CI: 59.7-60.9%). On the other hand, the prevalence of obesity (BMI ?30 kg/m2) increased significantly (1.6 points, 95% CI: 0.7-2.6) from 17.5% in 2005 to 19.2% in 2013. Although the prevalence of obesity increased in most countries, the only significant increase was observed in Germany (5.8 points, 95% CI: 1.8-9.9). Spain was the only country where the prevalence of obesity decreased significantly (-4.7 points, 95% CI: 8.8 to -0.5). Sex and age differences are reported. CONCLUSIONS: Although the prevalence of overweight was stable, the prevalence of obesity rose. Based on the data currently available for Europe, the prevalence of obesity in European older adults has already reached epidemic proportions, which reinforces the need for the development of effective healthy lifestyle programs.

PMID- 29569526 TI - Pharmacogenetics and the treatment of chronic myeloid leukemia: how relevant clinically? An update. AB - Despite the excellent efficacy and improved clinical responses obtained with imatinib mesylate (IM), development of resistance in a significant proportion of chronic myeloid leukemia (CML) patients on IM therapy have emerged as a challenging problem in clinical practice. Resistance to imatinib can be due to heterogeneous array of factors involving BCR/ABL-dependent and BCR/ABL independent pathways. Although BCR/ABL mutation is the major contributory factor for IM resistance, reduced bio-availability of IM in leukemic cells is also an important pharmacokinetic factor that contributes to development of resistance to IM in CML patients. The contribution of polymorphisms of the pharmacogenes in relation to IM disposition and treatment outcomes have been studied by various research groups in numerous population cohorts. However, the conclusions arising from these studies have been highly inconsistent. This review encompasses an updated insight into the impact of pharmacogenetic variability on treatment response of IM in CML patients. PMID- 29569528 TI - Capacity building for health inequality monitoring in Indonesia: enhancing the equity orientation of country health information system. AB - BACKGROUND: Inequalities in health represent a major problem in many countries, including Indonesia. Addressing health inequality is a central component of the Sustainable Development Goals and a priority of the World Health Organization (WHO). WHO provides technical support for health inequality monitoring among its member states. Following a capacity-building workshop in the WHO South-East Asia Region in 2014, Indonesia expressed interest in incorporating health-inequality monitoring into its national health information system. OBJECTIVES: This article details the capacity-building process for national health inequality monitoring in Indonesia, discusses successes and challenges, and how this process may be adapted and implemented in other countries/settings. METHODS: We outline key capacity-building activities undertaken between April 2016 and December 2017 in Indonesia and present the four key outcomes of this process. RESULTS: The capacity-building process entailed a series of workshops, meetings, activities, and processes undertaken between April 2016 and December 2017. At each stage, a range of stakeholders with access to the relevant data and capacity for data analysis, interpretation and reporting was engaged with, under the stewardship of state agencies. Key steps to strengthening health inequality monitoring included capacity building in (1) identification of the health topics/areas of interest, (2) mapping data sources and identifying gaps, (3) conducting equity analyses using raw datasets, and (4) interpreting and reporting inequality results. As a result, Indonesia developed its first national report on the state of health inequality. A number of peer-reviewed manuscripts on various aspects of health inequality in Indonesia have also been developed. CONCLUSIONS: The capacity building process undertaken in Indonesia is designed to be adaptable to other contexts. Capacity building for health inequality monitoring among countries is a critical step for strengthening equity-oriented national health information systems and eventually tackling health inequities. PMID- 29569529 TI - Applying the Innov8 approach for reviewing national health programmes to leave no one behind: lessons learnt from Indonesia. AB - The World Health Organization's Innov8 Approach for Reviewing National Health Programmes to Leave No One Behind is an eight-step process that supports the operationalization of the Sustainable Development Goals' commitment to 'leave no one behind'. In 2014-2015, Innov8 was adapted and applied in Indonesia to review how the national neonatal and maternal health action plans could become more equity-oriented, rights-based and gender-responsive, and better address critical social determinants of health. The process was led by the Indonesian Ministry of Health, with the support of WHO. It involved a wide range of actors and aligned with/fed into the drafting of the maternal newborn health action plan and the implementation planning of the newborn action plan. Key activities included a sensitization meeting, diagnostic checklist, review workshop and in-country work by the review teams. This 'methods forum' article describes this adaptation and application process, the outcomes and lessons learnt. In conjunction with other sources, Innov8 findings and recommendations informed national and sub-national maternal and neonatal action plans and programming to strengthen a 'leave no one behind' approach. As follow-up during 2015-2017, components of the Innov8 methodology were integrated into district-level planning processes for maternal and newborn health, and Innov8 helped generate demand for health inequality monitoring and its use in planning. In Indonesia, Innov8 enhanced national capacity for equity-oriented, rights-based and gender-responsive approaches and addressing critical social determinants of health. Adaptation for the national planning context (e.g. decentralized structure) and linking with health inequality monitoring capacity building were important lessons learnt. The pilot of Innov8 in Indonesia suggests that this approach can help operationalize the SDGs' commitment to leave no one behind, in particular in relation to influencing programming and monitoring and evaluation.

PMID- 29569532 TI - The relationship between self-efficacy and transition to work or studies in young adults with disabilities. AB - AIM: To investigate perceived self-efficacy in unemployed young adults with disabilities, and the association between self-efficacy and transition to work or studies. METHODS: This prospective cohort study collected data through self report questionnaires and registry data from a vocational rehabilitation project with young adults, aged 19-29 years. The Swedish Social Insurance Agency, the Swedish Public Employment Service and the participating municipalities identified potential participants for the study. A total of 531 participants were included in the study, of which 249 (47%) were available for analysis. Multinomial logistic regression models were carried out to estimate the associations between self-efficacy, demographic (age, country of birth, education level), health and employment status. The latter was coded as: 'no transition to work or studies', 'transition to studies', and 'transition to work'. RESULTS: A higher level of self-efficacy was associated with increased odds for 'transition to work' (OR = 2.37, p < 0.05). This finding remained consistent when adjusting for possible confounders. The mean value of self-efficacy was low, and participants with lower self-efficacy reported worse self-rated health ( p < 0.001) compared to participants with higher self-efficacy. CONCLUSIONS: The results from this study suggest that self-efficacy should be addressed in the vocational rehabilitation of young adults with disabilities in order to support their transition and integration into the labour market.

AB - Balanced vegetarian diets are popular, although they are nearly absent in creatine and carnosine and contain considerably less carnitine than non vegetarian diets. Few longitudinal intervention studies investigating the effect of a vegetarian diet on the availability of these compounds currently exist. We aimed to investigate the effect of transiently switching omnivores onto a vegetarian diet for 6 months on muscle and plasma creatine, carnitine and carnosine homeostasis. In a 6-month intervention, forty omnivorous women were ascribed to three groups: continued omnivorous diet (control, n 10), vegetarian diet without supplementation (Veg+Pla, n 15) and vegetarian diet combined with daily beta-alanine (0.8-0.4 g/d) and creatine supplementation (1 g creatine monohydrate/d) (Veg+Suppl, n 15). Before (0 months; 0M), after 3 months (3M) and 6 months (6M), a fasted venous blood sample and 24-h urine was collected, and muscle carnosine content was determined by proton magnetic resonance spectroscopy (1H-MRS). Muscle biopsies were obtained at 0M and 3M. Plasma creatine and muscle total creatine content declined from 0M to 3M in Veg+Pla (P=0.013 and P=0.009, respectively), whereas plasma creatine increased from 0M in Veg+Suppl (P=0.004). None of the carnitine-related compounds in plasma or muscle showed a significant time*group interaction effect. 1H-MRS-determined muscle carnosine content was unchanged over 6M in control and Veg+Pla, but increased in Veg+Suppl in soleus (P<0.001) and gastrocnemius (P=0.001) muscle. To conclude, the body creatine pool declined over a 3-month vegetarian diet in omnivorous women, which was ameliorated when accompanied by low-dose dietary creatine supplementation. Carnitine and carnosine homeostasis was unaffected by a 3- or 6-month vegetarian diet, respectively. PMID- 29569536 TI - Introduction of iodised salt benefits infants' mental development in a community based cluster-randomised effectiveness trial in Ethiopia. AB - The effectiveness of salt iodisation in improving the mental development of young children has not been assessed. We implemented a community-based cluster randomised effectiveness trial in sixty randomly selected districts in the Amhara region of Ethiopia. We randomly allocated each district to treatment and randomly selected one of its villages. In parallel to national salt iodisation efforts, iodised salt was brought early into the markets of the thirty intervention villages before it became widely available in the thirty control villages 4-6 months later. The primary outcome was children's mental development scores on the Bayley Scales. This was an intention-to-treat analysis using mixed linear models adjusted for covariates and clusters. The trial was registered at ClinicalTrials.gov, NCT013496. We assessed 1835 infants aged 5-11 months at baseline. The same children (85 % of the sample) were re-assessed at 20-29 months when all villages had iodised salt. At endline, urinary iodine concentration was higher in children in the intervention group compared with those in the control group (median 228.0 v. 155.1 ug/l, P=0.001). The intervention group had higher scores compared with the control group on the Bayley composite score (raw scores:130.60 v. 128.51; standardised scores: 27.8 v. 26.9; d=0.13; 95 % CI 0.02, 0.23) and three of the four subscales: cognitive (53.27 v. 52.54, d=0.13; 95 % CI 0.03, 0.23), receptive language (20.71 v. 20.18, d=0.13; 95 % CI 0.03, 0.24) and fine motor (35.45 v. 34.94, d=0.15; 95 % CI 0.04, 0.25). The introduction of iodised salt contributes to children's higher urinary iodine concentration and mental development. PMID- 29569537 TI - A preclinical study to model taurine pharmokinetics in the undernourished rat. AB - Malnutrition is a common feature of chronic and acute diseases, often associated with a poor prognosis, including worsening of clinical outcome, owing, among other factors, to dysfunction of the most internal organs and systems affecting the absorption, metabolism and elimination of drugs and nutrients. Taurine is involved in numerous biological processes and is required in increased amounts in response to pathological conditions. The aim of this study was to describe the behaviour of taurine in well-nourished (WN) rats and to analyse the influence of protein-energy undernutrition on the pharmacokinetic (PK) parameters of taurine, using a PK model. Wistar rats were randomly distributed into two groups, WN and undernourished (UN), and taurine was administered intravenously or orally at different doses: 1, 10 and 100 mg. Population pharmacokinetic modelling of plasma levels was performed using the NONMEM 7.2 program. Several distribution and absorption models were explored in combination with dose and/or time covariate effects. Covariates such as nutritional status, serum albumin, body weight and score of undernutrition were used. A two-compartment population pharmacokinetic model with zero-order endogenous formation, passive absorption, first-order kinetics distribution and non-linear elimination with parallel Michaelis-Menten excretion and reabsorption processes best described taurine pharmacokinetics. Undernutrition acted as a covariate reducing the V max of the active elimination process. Data analysis showed linear absorption and distribution, and non-linear elimination processes for taurine. Elimination of taurine was reduced in UN animals, suggesting that the reabsorption process via the secretion transporter was modified in that group. PMID- 29569538 TI - Serum metabolomics study of nutrient metabolic variations in chronic heat stressed broilers. AB - To investigate the effects of heat stress on broiler metabolism, we assigned 144 broilers to normal control (NC), heat stress (HS) or pair-fed (PF) groups and then monitored the effects using growth performance, carcass characteristics, biochemical assays and GC-MS-based metabolomics. The up-regulation of cloacal temperature confirmed that our experiment was successful in inducing chronic heat stress. The average daily gain and average daily feed intake of the HS group were significantly lower than those of the NC group, by 28.76 and 18.42 %, respectively (P1 and P<0.05). The greater feed:gain ratio of the HS group was significantly positively correlated with the leg, abdominal fat, subcutaneous fat and intramuscular fat proportions and levels of some free amino acids (proline, l cysteine, methionine and threonine) but was negatively correlated with breast proportion and levels of some NEFA (stearic acid, arachidonic acid, palmitic acid and oleic acid). These findings indicated that the heat-stressed broilers were in negative energy balance and unable to effectively mobilise fat, thereby resulting in protein decomposition, which subsequently affected growth performance and carcass characteristics. PMID- 29569539 TI - Postprandial glycaemic and lipaemic responses to chronic coffee consumption may be modulated by CYP1A2 polymorphisms. AB - There is much epidemiological evidence suggesting a reduced risk of development of type 2 diabetes (T2D) in habitual coffee drinkers, however to date there have been few longer-term interventions, directly examining the effects of coffee intake on glucose and lipid metabolism. Previous studies may be confounded by inter-individual variation in caffeine metabolism. Specifically, the rs762551 SNP in the CYP1A2 gene has been demonstrated to influence caffeine metabolism, with carriers of the C allele considered to be of a 'slow' metaboliser phenotype. This study investigated the effects of regular coffee intake on markers of glucose and lipid metabolism in coffee-naive individuals, with novel analysis by rs762551 genotype. Participants were randomised to either a coffee group (n 19) who consumed four cups/d instant coffee for 12 weeks or a control group (n 8) who remained coffee/caffeine free. Venous blood samples were taken pre- and post intervention. Primary analysis revealed no significant differences between groups. Analysis of the coffee group by genotype revealed several differences. Before coffee intake, the AC genotype ('slow' caffeine metabolisers, n 9) displayed higher baseline glucose and NEFA than the AA genotype ('fast' caffeine metabolisers, n 10, P<0.05). Post-intervention, reduced postprandial glycaemia and reduced NEFA suppression were observed in the AC genotype, with the opposite result observed in the AA genotype (P<0.05). These observed differences between genotypes warrant further investigation and indicate there may be no one-size fits-all recommendation with regard to coffee drinking and T2D risk. PMID- 29569540 TI - Leucine promotes differentiation of porcine myoblasts through the protein kinase B (Akt)/Forkhead box O1 signalling pathway. AB - Leucine, one of the branched-chain amino acids, is the only amino acid to regulate protein turnover in skeletal muscle. Leucine not only increases muscle protein synthesis, but also decreases muscle protein degradation. It is well documented that leucine plays a positive role in differentiation of murine muscle cells. However, the role of leucine on porcine myoblast differentiation and its mechanism remains unclear. In this study, porcine myoblasts were induced to differentiate with differentiation medium containing different concentrations of leucine, and wortmannin was used to interdict the activity of protein kinase B (Akt). We found that leucine increased the number of myosin heavy chain-positive cells and creatine kinase activity. Moreover, leucine increased the mRNA and protein levels of myogenin and myogenic determining factor (MyoD). In addition, leucine increased the levels of phosphorylated Akt/Akt and phosphorylated Forkhead box O1 (P-FoxO1)/FoxO1, as well as decreased the protein level of FoxO1. However, wortmannin, a specific repressor of PI3K/Akt signalling pathway, attenuated the positive role of leucine on porcine myoblast differentiation. Our results suggest that leucine promotes porcine myoblast differentiation through the Akt/FoxO1 signalling pathway. PMID- 29569541 TI - Energy efficiency of digestible protein, fat and carbohydrate utilisation for growth in rainbow trout and Nile tilapia. AB - Currently, energy evaluation of fish feeds is performed on a digestible energy basis. In contrast to net energy (NE) evaluation systems, digestible energy evaluation systems do not differentiate between the different types of digested nutrients regarding their potential for growth. The aim was to develop an NE evaluation for fish by estimating the energy efficiency of digestible nutrients (protein, fat and carbohydrates) and to assess whether these efficiencies differed between Nile tilapia and rainbow trout. Two data sets were constructed. The tilapia and rainbow data set contained, respectively, eight and nine experiments in which the digestibility of protein, fat and energy and the complete energy balances for twenty-three and forty-five diets was measured. The digestible protein (dCP), digestible fat (dFat) and digestible carbohydrate intakes (dCarb) were calculated. By multiple regression analysis, retained energy (RE) was related to dCP, dFat and dCarb. In tilapia, all digestible nutrients were linearly related to RE (P<0.001). In trout, RE was quadratically related to dCarb (P<0.01) and linearly to dCP and dFat (P<0.001). The NE formula was NE=11.5*dCP+35.8*dFAT+11.3*dCarb for tilapia and NE=13.5*dCP+33.0*dFAT+34.0*dCarb 3.64*(dCarb)2 for trout (NE in kJ/(kg0.8*d); dCP, dFat and dCarb in g/(kg0.8*d)). In tilapia, the energetic efficiency of dCP, dFat and dCarb was 49, 91 and 66 %, respectively, showing large similarity with pigs. Tilapia and trout had similar energy efficiencies of dCP (49 v. 57 %) and dFat (91 v. 84 %), but differed regarding dCarb. PMID- 29569542 TI - Innate differences and colostrum-induced alterations of jejunal mucosal proteins in piglets with intra-uterine growth restriction. AB - Mammalian neonates undergo rapid transitions from a sterile uterine environment with a continuous intravenous supply of nutrients to a microbe-rich environment with intermittent ingesting of colostrum/milk via the gut. Currently, little is known about the colostrum-induced alterations of intestinal mucosal proteins in piglets with intra-uterine growth restriction (IUGR). In this study, we sought to investigate the innate differences and effects of colostrum on alterations in small-intestinal proteomes of IUGR piglets. Two IUGR (approximately 0.9 kg) and two normal-birth weight (NBW; approximately 1.3 kg) piglets were obtained from each of six sows at birth. One half (n 12; 6 IUGR v. 6 NBW) of the selected newborn piglets were killed to obtain jejunum samples, and the other half (n 12; 6 IUGR v. 6 NBW) of the newborn piglets were allowed to suckle colostrum from their own mothers for 24 h before jejunum sample collection. On the basis of proteomic analysis, we identified thirty-one differentially expressed proteins in the jejunal mucosa between IUGR and normal neonates before or after colostrum consumption. The intestinal proteins altered by colostrum feeding play important roles in the following: (1) increasing intestinal integrity, transport of nutrients, energy metabolism, protein synthesis, immune response and, therefore, cell proliferation; and (2) decreasing oxidative stress, and therefore cell apoptosis, in IUGR neonates. However, colostrum only partially ameliorated the inferior status of the jejunal mucosa in IUGR neonates. These findings provide the first evidence in intestinal protein alterations of IUGR neonates in response to colostrum ingestion, and thus render new insights into the mechanisms responsible for impaired growth in IUGR neonates and into new nutritional intervention strategies. PMID- 29569543 TI - Effect of nutritional supplement on bone marrow-derived mesenchymal stem cells from aplastic anaemia. AB - Aplastic anaemia (AA) is characterised by pancytopenia resulting from a marked reduction in haemopoietic stem cells (HSC). The regulation of haemopoiesis depends on the interaction between HSC and various cells of the bone marrow (BM) microenvironment, including BM-derived mesenchymal stromal cells (BMSC). The purpose of this study was to analyse the biological effect of nutritional supplement (NS), a dietary supplement consisting of thirty-six compounds: amino acids, nucleotides, vitamins and micronutrients on the BMSC of AA rats. The AA rat model was established by irradiating X-ray (2.5 Gy) and intraperitoneal injections of cyclophosphamide (35 mg/kg; Sigma) and chloramphenicol (35 mg/kg; Sigma). Then AA rats were fed with NS in a dose-dependent manner (2266.95, 1511.3, 1057.91 mg/kg d) by intragastric administration. The effect of NS on the BMSC of AA rats was analysed. As compared with AA rats, NS treatment significantly improved these peripheral blood parameters and stimulated the proliferation of total femoral nucleated cells. NS treatment affected proliferative behaviour of BMSC and suppressed BMSC differentiation to adipocytes. Furthermore, NS treatment of AA rats accelerated osteogenic differentiation of BMSC and enhanced bone mineral density. Co-incubation of HSC with mesenchymal stromal cells and serum from AA rats subjected to high-dose NS markedly improved the yield of CD34+cells. Protein microarray analysis revealed that there were eleven differentially expressed proteins in the NS group compared with the AA rat group. The identified specific NS might be implicated in rehabilitation of BMSC in AA rats, suggesting their potential of nutritional support in AA treatment. PMID- 29569544 TI - A comparison between two healthy diet scores, the modified Mediterranean diet score and the Healthy Nordic Food Index, in relation to all-cause and cause specific mortality. AB - High adherence to healthy diets has the potential to prevent disease and prolong life span, and healthy dietary pattern scores have each been associated with disease and mortality. We studied two commonly promoted healthy diet scores (modified Mediterranean diet score (mMED) and the Healthy Nordic Food Index (HNFI)) and the combined effect of the two scores in association with all-cause and cause-specific mortality (cancer, CVD and ischaemic heart disease). The study included 38 428 women (median age of 61 years) from the Swedish Mammography Cohort. Diet and covariate data were collected in a questionnaire. mMED and HNFI were generated and categorised into low-, medium- and high-adherence groups, and in nine combinations of these. Multivariable-adjusted hazard ratios (HR) of register-ascertained mortality and 95 % CI were calculated in Cox proportional hazards regression analysis. During follow-up (median: 17 years), 10 478 women died. In the high-adherence categories compared with low-adherence categories, the HR for all-cause mortality was 0.76 (95 % CI 0.70, 0.81) for mMED and 0.89 (95 % CI 0.83, 0.96) for HNFI. Higher adherence to mMED was associated with lower mortality in each stratum of HNFI in the combined analysis. In general, mMED, compared with HNFI, was more strongly associated with a lower cause-specific mortality. In Swedish women, both mMED and HNFI were inversely associated with all-cause and cardiovascular mortality. The combined analysis, however, indicated an advantage to be adherent to the mMED. The present version of HNFI did not associate with mortality independent of mMED score. PMID- 29569545 TI - The potential of flow-through microdialysis for probing low-molecular weight organic anions in rhizosphere soil solution. AB - In this paper, flow-through microdialysis is presented as a novel analytical tool for automatic sampling of low molecular weight organic anions (LMWOA), such as oxalate and citrate, in solid samples of environmental concern. The microsampling methodology involves the implantation of dedicated capillary-type probes offering unrivalled spatial resolution (ca. 200MUm) in definite soil sites. These passive samplers are aimed at monitoring local processes, such as the release of organic acids occurring in the rhizosphere environment, in nearly real-time. The influence of chemical and physical variables (composition and flow rate of the perfusion liquid, ionic strength and pH of the outer medium and presence of metal ions therein) was assessed in vitro using liquid-phase assays. On the other hand, the resistance of the external solid medium to mass transfer, and the actual applicability of in vivo calibration methods were investigated using quartz sand as an inert model soil. Microdialysers furnished with 3cm long semipermeable tubular membranes were perfused with 0.01M NaNO3 at a flow rate of 2.0MUl/min, yielding dialysis recoveries >=45% for both assayed LMWOAs in simulated background soil electrolyte solutions, and >=24% in the interstitial liquid of complex solid samples. Full knowledge of the fate of LMWOAs in soils was obtained through the application of stimulus-response approaches that mimic the discrete exudation pulses of roots. Highly time-resolved microdialysates were used to discern readily available species such as free carboxylic anions and LMW metal organic acid complexes from adsorbed, precipitated or mineralised analyte species in a variety of soil samples containing variable amounts of organic matter, exchangeable cations and different levels of metal pollution.

AB - This study examined standard solutions to assess the influence of the gas flow rate and organic solvent type on losses caused by gas blowdown of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/DFs) and coplanar polychlorinated biphenyls (Co-PCBs). Results obtained here will contribute to maintaining analytical method performance and system quality for PCDD/DFs and Co-PCBs analyses. An organic solvent (with 0.5ml each of acetone, dichloromethane, n hexane, and toluene), PCDD/DFs or Co-PCBs, and their 13C12-labeled compounds were put separately into 10ml pear-shaped flasks. The samples were blown to dryness at room temperature until the last trace of solvent disappeared. They were subsequently reconstituted in those flasks. Analyte recoveries were calculated by comparing blown samples to those that had not been blown. Recoveries of Co-PCBs were more affected than those of PCDD/DFs when the gas flow rates were set at 203, 261, 332, and 456ml/min. Losses of Co-PCBs were least at 203-332ml/min. Regarding losses of PCDD/DFs and Co-PCBs, the toluene solution showed the least variation in recovery. An actual soil sample extract was also examined using optimized conditions for the gas flow rate and solvent types obtained by experiments in standard solutions. Thereby, the blowdown conditions gave quantitative recoveries of 13C12-labeled compounds in the sample extract.

AB - The characterization of the aroma profile of 33 samples of Madeira wine from five monovarieties (Sercial, Verdelho, Boal, Malvasia and Tinta Negra Mole) having different type and categories is presented, using solid phase microextraction and stir bar sorptive extraction techniques (SPME and SBSE) followed by capillary gas chromatography and mass spectrometry detection (GC-MS). Headspace SPME/GC-MS provided effectiveness to identify the major constituents of the aroma profile of Madeira wine, where no remarkable differences occur among the samples studied. The volatile compounds are mainly constituted by ethyl octanoate (11.3-256.9MUgL 1), ethyl decanoate (21.5-210.5MUgL-1), ethyl decenoate (0.1-112.8MUgL-1), diethyl succinate (0.9-65.6MUgL-1), ethyl dodecanoate (1.2-6.5MUgL-1), ethyl nonanoate (0.6-5.2MUgL-1), ethyl hexanoate (0.2-3.7MUgL-1) and isoamyl octanoate (0-2.2MUgL-1). C13 norisoprenoids such as vitispirane (0.9-7.0MUgL-1) and 1,1,6 trimethyl 1,2-dihydro naphthalene (0.7-12.5MUgL-1), as well as phenyl ethanol (0 8.1MUgL-1), were also found in Madeira wine samples. The powerful capabilities of SBSE followed thermal desorption and GC-MS analysis allowed higher ability for profiling traces and ultra traces of compounds in Madeira wine samples, including esters (80.7-89.7%), carboxylic acids (1.6-4.2%), alcohols (3.5-8.2%), aldehydes (0.9-3.7%), pyrans (0.2-1.7%), lactones (<3%), monoterpenes (0.1-1.4%), sesquiterpenes (0.1-0.8%) and C13 norisoprenoids (1.7-6.5%), which some of them play a remarkable impact on the aroma complexity. C13 norisoprenoids in particular, seem to play an important role on Madeira wine bouquet since presenting very low sensorial threshold limits. Excellent correlation between Madeira wine ageing and the abundance of cis-oak lactone was attained showing to be an important chemical descriptor to characterize reserves and Vintages as well as a contributor to wine flavour. The differentiation between reserves, dry/medium dry and sweet/medium sweet young wines could be well established by means of chemometric analysis, using particular aroma compounds such as diethyl succinate, cis-oak lactone and ethyl octanoate as discriminating variables. PMID- 29569548 TI - An assisted approach of the global optimization for the experimental conditions in capillary electrophoresis. AB - Experimental conditions have effect on the separation of capillary electrophoresis (CE) directly. In this work, a set of index to describe the separation in CE was established properly. Based on a combination of genetic algorithm and least square support vector machine, an assisted approach of global optimization for experimental conditions was proposed for the first time, and it was applied to the separation of four synthetic compounds by CE in nonaqueous system. Under the optimum conditions obtained by this approach, the result of the experiment was satisfactory and proved that this novel approach was effective. Furthermore, we investigated the most important conditions that mainly affect the separation effectiveness of CE by partial least squares regression analysis. Because of the generalization of this new approach proposed, it can be applied to the optimization of other experimental processes. PMID- 29569549 TI - Enantioseparation of dansyl amino acids by a novel permanently positively charged single-isomer cyclodextrin: Mono-6-N-allylammonium-6-deoxy-beta-cyclodextrin chloride by capillary electrophoresis. AB - A permanently positively charged single-isomer beta-CD, mono-6-N-allylammonium-6 deoxy-beta-CD chloride, ALAM-beta-CD, has been synthesized and successfully used as chiral selector in capillary electrophoresis for enantioseparation of amino acids and dansyl amino acids. The effects of pH, CD's concentration and capillary length on enantioseparation were studied in order to investigate its potential as chiral selector for acidic racemates. By increasing buffer's pH and CD's concentration, fairly robust separations were achieved. Good separations were also obtained with a shorter capillary. In addition, baseline enantiomeric separations of a mixture of six pairs of dansyl dl-amino acids were achieved under different pH conditions. PMID- 29569550 TI - Electrochemical hydride generation atomic absorption spectrometry for determination of cadmium. AB - An electrolytic hydride generation system for determination of another hydride forming element, cadmium, by catholyte variation electrochemical hydride generation (EcHG) atomic absorption spectrometry is described. A laboratory-made electrolytic cell with lead-tin alloy as cathode material is designed as electrolytic generator of molecular hydride. The influences of several parameters on the analytical signal have been evaluated using a Plackett-Burman experimental design. The significant parameters such as cathode surface area, electrolytic current, carrier gas flow rate and catholyte concentration have been optimized using univariate method. The analytical figures of merit of procedure developed were determined. The calibration curve was linear up to 20ngml-1of cadmium. The concentration detection limit (3sigma, n=8) of 0.2ngml-1 and repeatability (relative standard deviation, n=7) of 3.1% were achieved at 10.0ngml-1. It was shown that interferences from major constituents at high concentrations were significant. The accuracy of method was verified using a real sample (spiked tap water) by standard addition calibration technique. Recovery of 104% was achieved for Cd in the spiked tap water sample. PMID- 29569551 TI - A sol-gel immobilization of nano and micron size sorbents in poly(dimethylsiloxane) (PDMS) microchannels for microscale solid phase extraction (SPE). AB - Sorbent particles consisting of nano and micro silica, and micron size octadecylsilica (ODS) were immobilized using sol-gel chemistry onto poly(dimethylsiloxane) (PDMS) microfluidic channels to serve as MU-chip solid phase extraction (SPE) devices. Extraction, preconcentration and purification of biological and chemical analytes were carried out using these. Micro and nano scale silica-immobilized MU-SPE were used for the extraction/purification of DNA from recombinant Escherichia coli crude lysate. The average DNA recovery was 77+/ 9% (X+/-R.S.D.) for the micron size silica particles and 70+/-5% (X+/-R.S.D.) for the nano silica particles. The extracted DNA could be amplified by polymerase chain reaction (PCR) whereas the DNA from the crude lysate solution could not be. This was a testimony to the purification capability of the MU-SPE device. ODS immobilized MU-SPE were used to study the extraction efficiency (EE) and enhancement factor (EF) for three groups of organic compounds, aromatics, phenols and carboxylic acids. They showed poor recovery and low enrichment because the analytes sorbed into the PDMS and were not quantitatively extracted. PMID- 29569552 TI - Molecularly imprinted polyethersulfone microspheres for the binding and recognition of bisphenol A. AB - BPA-imprinted polyethersulfone (PES) microspheres for the binding and recognition of bisphenol A (BPA) were fabricated by means of a liquid-liquid phase separation technique. The imprinted novel PES microspheres had a porous structure with a skin layer, under which was followed by a finger-like structure. The recognition experiments with the BPA-imprinted microspheres were carried out by applying the microspheres to various BPA solutions. In water, high binding amounts of BPA were observed in the range of 19-42MUmol/g capacity, but the recognition was low in the BPA water solution. With the increase of the concentration in BPA solution, the binding amounts and the recognition coefficient increased. However, 1,4 butylene glycol/water media showed high recognition of the imprinted microspheres with a low binding capacity of BPA. In addtion, with the increase of the BPA amounts in the PES solution used to prepare the imprinted microspheres, the specific recognition sites increased, and the recognition ability increased. Evidence revealed that microsphere recognition was effective for BPA due to the binding to specific recognition sites [S](sites). The imprinted microspheres showed the selectivity for BPA in the wine including BPA and other organic compounds. Charge transfer and special cavities could be employed to explain the mechanism. PMID- 29569553 TI - Spectral filtering of light-emitting diodes for fluorescence detection. AB - The use of light-emitting diodes (LEDs) for fluorescence detection has recently gained much interest. The broad wavelength emission of LEDs requires spectral filtering that is not necessary when using a laser. For instance, filtering the LED light using a bandpass filter improves the signal-to-background ratio for riboflavin by a factor of 70. The bandwidth of the necessary bandpass filters affects both the signal and the background in these measurements. Fluorescence signal can be maximized with wider-bandpass high-transmittance filters. Background is governed by scattering of the LED emission light transmitted by two bandpass filters. When there is large crosstalk between the filters, the LED intensity is linearly related to the background. By estimating and optimizing the crosstalk between excitation and emission filters with a method presented here, the signal-to-background can be optimized. Bandpass filters should be selected with sharp on-off transition, strong blocking outside their transmitting region and the widest bandwidth with minimal crosstalk. Using optimized spectral filtering and capillary electrophoresis analysis, LODs of 50, 3 and 20nM are obtained for riboflavin, fluorescein and eosin Y, respectively. These results are superior to those reported in the literature for 5mW LEDs. PMID- 29569554 TI - Sizes of water-soluble luminescent quantum dots measured by fluorescence correlation spectroscopy. AB - In this paper, fluorescence correlation spectroscopy (FCS) was applied to measure the size of water-soluble quantum dots (QDs). The measurements were performed on a home-built FCS system based on the Stokes-Einstein equation. The obtained results showed that for bare CdTe QDs the sizes from FCS were larger than the ones from transmission electron microscopy (TEM). The brightness of QDs was also evaluated using FCS technique. It was found that the stability of the surface chemistry of QDs would be significantly improved by capping it with hard-core shell. Our data demonstrated that FCS is a simple, fast, and effective method for characterizing the fluorescent quantum dots, and is especially suitable for determining the fluorescent nanoparticles less than 10nm in water solution. PMID- 29569555 TI - Multivariate curve resolution analysis excitation-emission matrices of fluorescence of humic substances. AB - Excitation-emission matrices (EEM) of fluorescence of aqueous solutions of humic substances (HS), and sets of EEM acquired as function of the HS concentration, were analysed by multivariate curve resolution alternating least squares (MCR ALS). Three types of HS samples were studied: one commercial humic acid; two samples of fulvic acid (FA) extracted from a pinewood soil; two samples of FA extracted from recycled wastes. The fluorescence measurements were carried out at HS concentration between 5 and 100mg/L and at pH 6. The application of MCR-ALS algorithm on each individual EEM, as well as on column-wise augmented matrices, allows the identification of three major fluorophores in all HS samples analysed. The emission and excitation spectra of these fluorophores were recovered and are characteristic of each sample. Moreover, the variation of the fluorescence intensities of each fluorophore with HS concentration shows deviations from linearity at HS concentration higher than 30mg/L, depending on the fluorophore and/or sample. This behaviour reveals the existence of inner filter effects that affect the proportionally between the fluorescent signal and concentration but do not provoke measurable distortions on the fluorescence spectra of the detected fluorophores. PMID- 29569556 TI - Sensitive determination of captopril by time-resolved chemiluminescence using the stopped-flow analysis based on potassium permanganate oxidation. AB - The chemiluminescent behaviour of captopril when reacted with a common oxidant, potassium permanganate in different acidic media is described, using the stopped flow technique in a continuous-flow system. A 22 bit analogue-to-digital converter that acquires analogue signals at -10 and +10V and allows the power supply to the peristaltic pump to be interrupted is used in the time-resolved chemiluminescence manifold to ensure rapid, efficient mixing of chemiluminescent reagent and sample immediately before reaching the detector; this results in high precision and detectability, particularly with fast, short-lived emissions. The optimum chemical conditions for the chemiluminescence emission were investigated. It was found that a weak CL emission was emitted during the oxidation of this drug with potassium permanganate in acidic solution. The effect of common emission enhancers such as formic acid, formaldehyde, glutaraldehyde, acetaldehyde, quinine, fluorescein, rhodamine B and rhodamine 6G was studied. The parameters selected were 4.0molL-1 sulphuric acid, 0.25mmolL-1 permanganate and 0.75molL-1 formaldehyde. Four quantitative parameters adjustable via software settings, two of them typically kinetic parameters, such as rate of the light development reaction and rate of the light-decay reaction, and the other conventional parameters, such as maximum emission intensity and total emission area, were used to obtain linear calibration graphs with each measurement parameter. The detection limits ranged from 0.011 to 0.026MUgmL-1 and R.S.D. values (n=10) of 1.21-3.93 at a 0.50MUgmL-1 and 2.01-3.41 at a 1.60MUgmL-1 concentration levels were obtained. The method was satisfactorily applied to the determination of captopril in pharmaceutical preparations. PMID- 29569557 TI - The use of Nafion-coated thin mercury film electrodes for the determination of the dissolved copper speciation in estuarine water. AB - Differential pulse anodic stripping voltammetry (DPASV) using a Nafion-coated thin mercury film electrode (NCTMFE) was implemented to determine the dissolved copper speciation in saline estuarine waters containing high concentrations of dissolved organic matter (DOM). The study used model ligands and estuarine water from San Francisco Bay, California, USA to demonstrate that the NCTMFE is more effective at distinguishing between electrochemically inert and labile copper species when compared to the conventional thin mercury film electrode (TMFE). Copper titration results verify that the NCTMFE better deals with high concentrations of DOM by creating a size-exclusion barrier that prevents DOM from interacting with the mercury electrode when performing copper speciation measurements. Pseudovoltammograms were used to illustrate that copper complexes found in natural waters were more apt to be electrochemically inert at the NCTMFE relative to the TMFE when subjected to high negative overpotentials. Copper speciation results using the NCTMFE from samples collected in San Francisco Bay estimated that >99.9% of all copper was bound to strong copper-binding ligands. These L1-class ligands exceeded the concentration of total dissolved copper in all samples tested and control the equilibrium of ambient [Cu2+] in the San Francisco Bay estuary. PMID- 29569558 TI - Determination of aluminum as contaminant in dialysis concentrates by adsorptive cathodic stripping voltammetry. AB - This paper describes a stripping voltammetric method for the determination of aluminum as contaminant in dialysis concentrates. It is based on the adsorptive deposition of the complex Al-1,2-dihydroxyanthraquinone-3-sulfonic acid (DASA) at the hanging mercury drop electrode (HMDE) at -0.9V (versus Ag/AgCl) and its cathodic stripping during the potential scan. The method was optimized concerning the main electrochemical parameters that influence the voltammetric determination in highly saline solutions (sample dilution factor, deposition time and DASA concentration). The linear range for the measurements was from 70%). This study verified that the method is sufficiently precise, accurate and robust for field sampling at mercury contaminated sites. No interferences were observed from elevated levels of potential co-contaminants, Hg0 (125ngm-3) and H2S (1.27ppmv). PMID- 29569561 TI - Towards Drugs and Devices Synergy.

AB - Parkinson's disease (PD) is a common condition in nursing home (NH) residents. The primary treatment for Parkinson's disease is levodopa therapy to relieve motor symptoms and maximize physical function. Non-motor symptoms are highly prevalent in NH residents with Parkinson's disease and dramatically decrease quality of life. Choices in drug treatment need to take into account the complex interactions between aging, comorbidity and non-motor symptoms. Optimal management requires expertise and cooperative effort from prescribing neurologists and nursing home health professionals. The objective is to evaluate the pertinence of the CHEF, a new tool to screen daily life clinical data helpful for the management of neurologist consultants. NH nurses were asked to briefly report falls and gait problems, hallucinations, sleep disorders and motor fluctuations. Analysis of the results obtained in 26 patients showed that CHEF was perceived as a helpful complement to existing ressources. The use of this tool has the potential to enhance the quality of NH care of Parkinsonian patients. PMID- 29569563 TI - The decision-making capacity of elderly hospitalized patients: validation of a test on their choice of return home. AB - Elderly hospitalized patients have uncertain or questionable capacity to make decisions about their care. Determining whether an elderly patient possesses decision-making capacity to return at home is a major concern for geriatricians in everyday practice. To construct and internally validate a new tool, the dream of home test (DROM-test), as support for decision making hospitalization discharge destination for the elderly in the acute or sub-acute care setting. The DROM-test consists of 10 questions and 4 vignettes based upon the 4 relevant criteria for decision-making: capacity to understand information, to appreciate and reason about medical risks and to communicate a choice. A prospective observational study was conducted during 6 months in 2 geriatric care units in Bretonneau Hospital (Assistance publique, Hopitaux de Paris). We compared the patient decision of DROM-test regarding discharge recommendations with those of an Expert committee and of the team in charge of the patient. 102 were included: mean age 83.1 + 6.7 [70; 97], 66.67% females. Principal components analysis revealed four dimensions: choice, understanding, reasoning and understanding. The area under the ROC curve was 0.64 for the choice dimension, 0.59 for the understanding, 0.53 for the reasoning and 0.52 for the apprehension. Only the choice dimension was statistically associated with the decision of the committee of experts (p=0.017). Even though Drom-test has limitations, it provides an objective way to ascertain decision-making capacity for hospitalised elderly patients. PMID- 29569564 TI - Pilot study: effectiveness of a training program about autonomy in elderly patients hospitalized after an acute episode. AB - Patients hospitalized in rehabilitation after an acute episode is at high risk of functional impairment and require active measures to prevent loss of autonomy. Resistance training has been proved beneficial to improve physical performances of aged subjects in the community. However, the feasibility and effects of training programs has never been assessed among hospitalized patients after an acute medical episode. In this pilot study, we aimed to evaluate a personalized training program of adapted physical education teacher combining muscular reinforcement and endurance training among patients over 65 year-old hospitalized in a geriatric rehabilitation care setting. The principal outcome considered was the evolution of the SPPB (short physical performance battery) score from baseline, after the 3-week period of training. Thirty-eight patients (mean age> 80 years) participated to the program. The mean SPPB score at baseline was 6.37 points (standard deviation: 2.17). After the intervention, the SPPB showed a significant improvement of 2.50 points, to reach 8.87 points (standard deviation: +/-1.60; p=0.001). These results confirm the feasibility of resistance-training programs among hospitalized elderly. The observed improvements in terms of physic al performances also appear promising with regard to the prevention of loss of autonomy during rehabilitation after acute medical episodes.

AB - In this review of the literature on posterior cortical atrophy (PCA), the history of the disease is first told through the studies of Frank Benson and Oliver Sacks. Then, we detail the possible underlying pathologies, Alzheimer's disease being the most common cause. Clinical, cognitive, and biological features are described, with a specific focus on the neuroimaging. We also describe the emotional aspects of PCA. These aspects are often overlooked, but deserve a particular attention due to their impact on the quality of life and prognostic implications for the patients. A multilevel care strategy for PCA patients is suggested. PMID- 29569568 TI - Successful aging: analysis of the components of a gerontological paradigm. AB - Since the mid-20th century, scientist has been searching the components of successful or active aging. At the beginning of the 21st century, demographic aging is now a global issue and successful aging has emerged as a gerontological paradigm through nation and international policies. Conducting a comprehensive review of scientific literature on this paradigm offers the opportunity to identify the key components of successful aging. Based on the results of this approach, we show that the components are not limited to the functional and cognitive health of individuals. Multidimensionality of successful aging highlights the complexity of factors influencing the experiences of aging, and the variety of dimensions involved: functional, psychological, social, spiritual or environmental. Representations and aspirations of what would be successful aging differ from one society to another, from culture to another. The article proposes a framework for an exploratory analysis of the vulnerabilities of elderly not to assess the success of aging, but to capture the components of the well-being of people in old age. PMID- 29569569 TI - Vitamin D in adults: update on testing and supplementation. AB - Hypovitaminosis D, a frequent condition in adults, is accompanied by adverse skeletal and non-skeletal events. The objective of the present article was to propose an update on the indications and use of vitamin D testing and supplementation in adults. Among healthy middle-aged adults, the serum 25 hydroxyvitamin D (25(OH)D) target concentration is 50 nmol/L. Natural intakes (sun exposure and diet) are sufficient, and there is no indication for systematic blood test or supplementation. In middle-aged adults who are either sick or dependent or frail, natural intakes are generally insufficient but should be encouraged. In this population, the loading phase of the supplementation targets a 25(OH)D concentration of 75 nmol/L, and the pattern of supplementation (200,000 to 400,000 IU orally over 2 months) depends on the measure of circulating 25(OH)D (which is not reimbursed outside the scope defined by the French national authority for health). In adults over 65 years of age, the loading phase of the supplementation should be systematic and targets a concentration of 75 nmol/L (pattern of 300,000 IU orally over 3 months). Regardless of age, the loading phase should be followed by a long-term maintenance phase of supplementation to maintain the 25(OH)D concentration above the target. A measure of serum 25(OH)D is useful after 9 months of supplementation to adjust the frequency or dosage of supplements if necessary. PMID- 29569570 TI - Behavioral and psychological symptoms in Lewy body disease: a review. AB - Dementia with Lewy bodies (DLB) is a common neurodegenerative disease, second in terms of prevalence after Alzheimer's disease (AD). DLB may be suspected according to three core features which are cognitive and motor fluctuations, early visual hallucinations and parkinsonism; and more recently, according to the new criteria, REM sleep behavior disorder (RBD). Behavorial and psychological symptoms associated with DLB are more frequent, more severe and appear earlier than those found in other neurodegenerative diseases. They may be at the forefront and are a major diagnostic and therapeutic challenge. An improved knowledge of the pathophysiology and phenomenology associated to these symptoms can facilitate their identification as well as eliminating differential diagnoses. Managing these symptoms may require drugs when hallucinations are overwhelming and induce behavorial disorders. However, psychotropic medications are not well tolerated in this specific population and some antipsychotic drugs cannot be prescribed due to their side effects. Although further studies are needed on this subject, non-interventional treatments such as therapeutic strategies based on the patients and their caregivers appear to be essential. This paper offers a review which aims to help clinicians to identify behavioral and psychological symptoms in DLB and treat them in their daily practice. PMID- 29569571 TI - A foldable electrode array for 3D recording of deep-seated abnormal brain cavities. AB - OBJECTIVE: This study describes the design and microfabrication of a foldable thin-film neural implant and investigates its suitability for electrical recording of deep-lying brain cavity walls. APPROACH: A new type of foldable neural electrode array is presented, which can be inserted through a cannula. The microfabricated electrode is specifically designed for electrical recording of the cavity wall of thalamic lesions resulting from stroke. The proof-of-concept is demonstrated by measurements in rat brain cavities. On implantation, the electrode array unfolds in the brain cavity, contacting the cavity walls and allowing recording at multiple anatomical locations. A three-layer microfabrication process based on UV-lithography and Reactive Ion Etching is described. Electrochemical characterization of the electrode is performed in addition to an in vivo experiment in which the implantation procedure and the unfolding of the electrode are tested and visualized. MAIN RESULTS: Electrochemical characterization validated the suitability of the electrode for in vivo use. CT imaging confirmed the unfolding of the electrode in the brain cavity and analysis of recorded local field potentials showed the ability to record neural signals of biological origin. SIGNIFICANCE: The conducted research confirms that it is possible to record neural activity from the inside wall of brain cavities at various anatomical locations after a single implantation procedure. This opens up possibilities towards research of abnormal brain cavities and the clinical conditions associated with them, such as central post stroke pain. PMID- 29569572 TI - Squeezed vacuum states of light for gravitational wave detectors. AB - A century after Einstein's formulation of General Relativity, the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) made the first direct detection of gravitational waves. This historic achievement was the culmination of a world-wide effort and decades of instrument research. While sufficient for this monumental discovery, the current generation of gravitational wave detectors represent the least sensitive devices necessary for the task; improved detectors will be required to fully exploit this new window on the Universe. In this paper, we review the application of squeezed vacuum states of light to gravitational-wave detectors as a way to reduce quantum noise, which currently limits their performance in much of the detection band. PMID- 29569573 TI - Chronic softening spinal cord stimulation arrays. AB - OBJECTIVE: We sought to develop a cervical spinal cord stimulator for the rat that is durable, stable, and does not perturb the underlying spinal cord. APPROACH: We created a softening spinal cord stimulation (SCS) array made from shape memory polymer (SMP)-based flexible electronics. We developed a new photolithographic process to pattern high surface area titanium nitride (TiN) electrodes onto gold (Au) interconnects. The thiol-ene acrylate polymers are stiff at room temperature and soften following implantation into the body. Durability was measured by the duration the devices produced effective stimulation and by accelerated aging in vitro. Stability was measured by the threshold to provoke an electromyogram (EMG) muscle response and by measuring impedance using electrochemical impedance spectroscopy (EIS). In addition, spinal cord modulation of motor cortex potentials was measured. The spinal column and implanted arrays were imaged with MRI ex vivo, and histology for astrogliosis and immune reaction was performed. MAIN RESULTS: For durability, the design of the arrays was modified over three generations to create an array that demonstrated activity up to 29 weeks. SCS arrays showed no significant degradation over a simulated 29 week period of accelerated aging. For stability, the threshold for provoking an EMG rose in the first few weeks and then remained stable out to 16 weeks; the impedance showed a similar rise early with stability thereafter. Spinal cord stimulation strongly enhanced motor cortex potentials throughout. Upon explantation, device performance returned to pre-implant levels, indicating that biotic rather than abiotic processes were the cause of changing metrics. MRI and histology showed that softening SCS produced less tissue deformation than Parylene-C arrays. There was no significant astrogliosis or immune reaction to either type of array. SIGNIFICANCE: Softening SCS arrays meet the needs for research-grade devices in rats and could be developed into human devices in the future. PMID- 29569574 TI - Improved muscle activation using proximal nerve stimulation with subthreshold current pulses at kilohertz-frequency. AB - OBJECTIVE: Transcutaneous electrical nerve stimulation can help individuals with neurological disorders to regain their motor function by activating muscles externally. However, conventional stimulation technique often induces near simultaneous recruitment of muscle fibers, leading to twitch forces time-locked to the stimulation. APPROACH: To induce less synchronized activation of finger flexor muscles, we delivered clustered narrower pulses to the proximal segment of the median and ulnar nerves at a carrier frequency of either 10 kHz (with an 80 us pulse width) or 7.14 kHz (with a 120 us pulse width) (high-frequency mode, HF), and different clustered pulses were delivered at a frequency of 30 or 40 Hz. Conventional stimulation with pulse frequency of 30 or 40 Hz (low-frequency mode, LF) was used for comparison. With matched elicited muscle forces between the HF and LF modes, the force variation, the high-density electromyogram (EMG) signals recorded at the finger flexor muscles and stimulation-induced-pain levels were compared. MAIN RESULTS: The compound action potentials in the 10 kHz HF mode revealed a significant difference (i.e. a lower amplitude and area, and a wider duration) compared with the LF mode, indicating cancellations of asynchronized action potentials. A smaller fluctuation in the elicited forces in the 10 kHz mode further demonstrated the less synchronized activation of different motor units. These effects tended to be weaker in the 7.14 kHz HF condition. However, the levels of pain sensation was not reduced in the HF mode potentially due to the high charge density used in the HF mode. Our findings indicated that different nerve fibers were recruited asynchronously through summations of different numbers of subthreshold depolarizations in the HF mode. SIGNIFICANCE: Compared with the LF mode, the HF mode stimulation was capable of activating the nerve fibers in a less synchronized way, which is more similar to the physiological activation pattern. PMID- 29569575 TI - WIMP dark matter candidates and searches-current status and future prospects. AB - We review several current aspects of dark matter theory and experiment. We overview the present experimental status, which includes current bounds and recent claims and hints of a possible signal in a wide range of experiments: direct detection in underground laboratories, gamma-ray, cosmic ray, x-ray, neutrino telescopes, and the LHC. We briefly review several possible particle candidates for a weakly interactive massive particle (WIMP) and dark matter that have recently been considered in the literature. We pay particular attention to the lightest neutralino of supersymmetry as it remains the best motivated candidate for dark matter and also shows excellent detection prospects. Finally we briefly review some alternative scenarios that can considerably alter properties and prospects for the detection of dark matter obtained within the standard thermal WIMP paradigm. PMID- 29569576 TI - Urinary tract infection due to Fusarium oxysporum in an immunocompetent patient with chronic kidney disease. AB - Infections due to Fusarium species are collectively referred to as fusariosis. Fusarium oxysporum has been reported to cause keratitis, onychomycosis, skin infections, catheter associated fungemia and has not been described as a cause of urinary tract infection. Here, we present the first case of fusariosis with urinary tract involvement in a 67 year old male, with chronic kidney disease and type 2 diabetes mellitus. This case illustrates the ever increasing spectrum of rare but offending pathogenic fungi. Early diagnosis of infection with a specific pathogen may lead to changes in antifungal therapy and may be critical for an improved outcome.

AB - Volatile anesthetic preconditioning has been shown to be a potent way to provide myocardium protection against ischemia/reperfusion (I/R) injury; however, this cardioprotection is lost in senescent animal models and elderly patients. NFkB regulated genes have been linked to myocardial I/R injury and anesthetic preconditioning. Here, we investigated NFkB activation related to anesthetic preconditioning in aging rat myocardium. Isolated, Langendorff perfused rat hearts from Fischer 344 male rats, 24 months old, were randomly assigned to one of the three groups. The hearts of the control group were perfused with physiologic solution without any intervention. The hearts in the I/R group were subjected to 25 minutes ischemia and followed by 60 minutes reperfusion. The hearts in the treatment group were subjected to 10 minutes 2.5% sevoflurane, followed by 20 minutes washout and by 25 minutes ischemia and 60 minutes of reperfusion, respectively. Left ventricular developed pressure (LVDP) and left ventricular end-diastolic pressure (LVEDP) were measured. Western blot analysis was used to measure inhibitor of kB (IkB) and anti-apoptotic genes: A1, ILP, c IAP-2, Bcl-2, caspase 8 and caspase 9. Ischemia and reperfusion significantly decreased LVDP and increased LVEDP in aged rat hearts. Anesthetic preconditioning with sevoflurane did not change the effects I/R on LVDP and LVEDP, despite the fact that after treatment with anesthetic preconditioning, the levels of IkappaB, A1, ILP, caspase 8 and caspase 9 were significantly different compared to those of the control hearts. In conclusion, anesthetic preconditioning with sevoflurane does not improve myocardial systolic and diastolic functions. Our results suggest that the activation of NFkB regulated genes is different in the senescent myocardium and could account for loss of cardioprotection with aging.

AB - BackgroundGenetic variants responsible for childhood interstitial lung disease (chILD) have not been studied extensively in Japanese patients.MethodsThe study population consisted of 62 Japanese chILD patients. Twenty-one and four patients had pulmonary hypertension resistant to treatment (PH) and hypothyroidism, respectively. Analyses of genetic variants were performed in all 62 patients for SFTPC and ABCA3, in all 21 PH patients for FOXF1, and in a limited number of patients for NKX2.1.ResultsCausative genetic variants for chILD were identified in 11 (18%) patients: SFTPC variants in six, NKX2.1 variants in three, and FOXF1 variants in two patients. No patients had ABCA3 variants. All three and two patients with NKX2.1 variants had hypothyroidism and developmental delay, respectively. We found six novel variants in this study.ConclusionMutations in SFTPC, NKX2.1, and FOXF1 were identified among Japanese infants and children with chILD, whereas ABCA3 mutations were rare.

Oral microbiota generally exists in the form of a biofilm and plays a crucial role in maintaining oral homeostasis, protecting the oral cavity and preventing disease development. Human oral microbiota has recently become a new focus research for promoting the progress of disease diagnosis, assisting disease treatment, and developing personalised medicines. In this review, the scientific evidence supporting the association that endogenous and exogenous factors (diet, smoking, drinking, socioeconomic status, antibiotics use and pregnancy) modulate oral microbiota. It provides insights into the mechanistic role in which oral microbiota may influence systemic diseases, and summarises the challenges of clinical diagnosis and treatment based on the microbial community information. It provides information for noninvasive diagnosis and helps develop a new paradigm of personalised medicine. All these benefit human health in the post-metagenomics era.

AB - Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders in premenopausal women. Heterogeneous by nature, PCOS is defined by a combination of signs and symptoms of androgen excess and ovarian dysfunction in the absence of other specific diagnoses. The aetiology of this syndrome remains largely unknown, but mounting evidence suggests that PCOS might be a complex multigenic disorder with strong epigenetic and environmental influences, including diet and lifestyle factors. PCOS is frequently associated with abdominal adiposity, insulin resistance, obesity, metabolic disorders and cardiovascular risk factors. The diagnosis and treatment of PCOS are not complicated, requiring only the judicious application of a few well-standardized diagnostic methods and appropriate therapeutic approaches addressing hyperandrogenism, the consequences of ovarian dysfunction and the associated metabolic disorders. This article aims to provide a balanced review of the latest advances and current limitations in our knowledge about PCOS while also providing a few clear and simple principles, based on current evidence-based clinical guidelines, for the proper diagnosis and long-term clinical management of women with PCOS. PMID- 29569622 TI - Global epidemiology of hyperthyroidism and hypothyroidism. AB - Thyroid hormones are essential for growth, neuronal development, reproduction and regulation of energy metabolism. Hypothyroidism and hyperthyroidism are common conditions with potentially devastating health consequences that affect all populations worldwide. Iodine nutrition is a key determinant of thyroid disease risk; however, other factors, such as ageing, smoking status, genetic susceptibility, ethnicity, endocrine disruptors and the advent of novel therapeutics, including immune checkpoint inhibitors, also influence thyroid disease epidemiology. In the developed world, the prevalence of undiagnosed thyroid disease is likely falling owing to widespread thyroid function testing and relatively low thresholds for treatment initiation. However, continued vigilance against iodine deficiency remains essential in developed countries, particularly in Europe. In this report, we review the global incidence and prevalence of hyperthyroidism and hypothyroidism, highlighting geographical differences and the effect of environmental factors, such as iodine supplementation, on these data. We also highlight the pressing need for detailed epidemiological surveys of thyroid dysfunction and iodine status in developing countries.

AB - BACKGROUND: Services offered in the esthetic/beauty industry poses the risk of blood-borne infections (BBIs) due to carrying out invasive procedures. The study objective: was to assess the number of sharps injuries, occupational risk factors, and preventive methods used among cosmetologists. MATERIAL AND METHODS: The anonymous survey was conducted (February-April 2017) in randomly selected beauty/esthetic medicine clinics in Szczecin, Poland; 96 cosmetologists were invited. RESULTS: Eighty cosmetologists (83.3%), responded. The mean age of the group was 25 years (range: 20-60 years). The majority of the respondents (95%) used sharps while at work, 41.3% had suffered at least one sharps injury during their occupational career. Clippers were the most common injury-causing instrument (39.4%), and manicure/pedicure was the most common injury-causing procedure (51.5%); 84.8% of injuries were not reported. The number of injuries was associated with age (34.9% in the group of 20-29 years old respondents vs. 64.7% in respondents >= 30 years old, p = 0.05), work experience (32.6% in the respondents working for 1-3 years vs. 68.8%, in those working >= 7 years, p = 0.03), and working hours/week (28.9% in those working <= 40 h vs. 57.1% of those working > 40 h, p = 0.02). Needle recapping was reported by 47.5% of respondents, 13.8% did not dispose used needles into a container, 17.5% did not routinely use gloves. CONCLUSIONS: Cosmetologists are at risk of sharps injuries. Inconsistent use of preventive methods and failure to report incidents may result in contracting BBIs. There is a need to implement education and intervention measures to prevent occupational injuries, particularly with regard to cosmetologists aged over 30 years, with a longer professional experience, working over 40 h/week.

AB - The effects of neurodegenerative syndromes extend beyond cognitive function to involve key physiological processes, including eating and metabolism, autonomic nervous system function, sleep, and motor function. Changes in these physiological processes are present in several conditions, including frontotemporal dementia, amyotrophic lateral sclerosis, Alzheimer disease and the parkinsonian plus conditions. Key neural structures that mediate physiological changes across these conditions include neuroendocrine and hypothalamic pathways, reward pathways, motor systems and the autonomic nervous system. In this Review, we highlight the key changes in physiological processing in neurodegenerative syndromes and the similarities in these changes between different progressive neurodegenerative brain conditions. The changes and similarities between disorders might provide novel insights into the human neural correlates of physiological functioning. Given the evidence that physiological changes can arise early in the neurodegenerative process, these changes could provide biomarkers to aid in the early diagnosis of neurodegenerative diseases and in treatment trials.

This analysis also raises important questions about the propriety of a private company sponsoring such dual use research without appropriate oversight and highlights an important gap in United States dual use research regulations.

AB - Background: Complex networks are found in many domains and the control of these networks is a research topic that continues to draw increasing attention. This paper proposes a method of network control that attempts to maintain a specified target distribution of the network state. In contrast to many existing network control research works, which focus exclusively on structural analysis of the network, this paper also accounts for user actions/behaviours within the network control problem. Methods: This paper proposes and makes use of a novel distribution-based control method. The control approach is applied within a simulation of the real-valued voter model, which could have applications in problems such as the avoidance of consensus or extremism. The network control problem under consideration is investigated using various theoretical network types, including scale free, random, and small world. Results: It is argued that a distribution-based control approach may be more appropriate for several types of social control problems, in which the exact state of the system is of less interest than the overall system behaviour. The preliminary results presented in this paper demonstrate that a standard reinforcement learning approach is capable of learning a control signal selection policy to prevent the network state distribution from straying far from a specified target distribution. Conclusions: In summary, the results presented in this paper demonstrate the feasibility of a distribution-based control solution within the simulated problem. Additionally, several interesting questions arise from these results and are discussed as potential future work. PMID- 29569638 TI - Erratum: Correction of Acknowledgements.

AB - The re-creation of horsepox virus, an extinct orthopoxvirus with similarity to smallpox virus, has caused concerns in the biosecurity and biodefense communities that the technical capabilities achieved could advance the re-creation of smallpox virus by nefarious actors. The work is now published. While the authors went through due biosecurity diligence at their research institution and with the proper Canadian federal authorities, now that the experiments have been published, there is an opportunity to discuss the dual use risks and benefits of the research itself, as well as those associated with publication of such research-all of which challenge current policies. Here, an analytical framework is used to assess the risks and benefits of such dual use research, and relevant components of biosecurity policy and the biodefense enterprise (including the acquisition of medical countermeasures) in the United States are discussed. The authors emphasize the need to use such risk/benefit assessments at the onset of research and throughout its development, followed by an assessment for its responsible communication.

AB - Health information technology has increased accessibility of health and medical data and benefited medical research and healthcare management. However, there are rising concerns about patient privacy in sharing medical and healthcare data. A large amount of these data are in free text form. Existing techniques for privacy preserving data sharing deal largely with structured data. Current privacy approaches for medical text data focus on detection and removal of patient identifiers from the data, which may be inadequate for protecting privacy or preserving data quality. We propose a new systematic approach to extract, cluster, and anonymize medical text records. Our approach integrates methods developed in both data privacy and health informatics fields. The key novel elements of our approach include a recursive partitioning method to cluster medical text records based on the similarity of the health and medical information and a value-enumeration method to anonymize potentially identifying information in the text data. An experimental study is conducted using real-world medical documents. The results of the experiments demonstrate the effectiveness of the proposed approach.

AB - Background: Very little is known about influenza viruses circulating in the Democratic Republic of Congo (DRC). We aim to characterize genetically and antigenically Influenza A(H3N2) and A(H1N1)pdm09 viruses circulating in the country. Methods: From August to December 2014, specimens were collected from patients with influenza like-illness (ILI) or severe acute respiratory infection (SARI) in various surveillance sites. Specimens were tested using real time reverse transcription polymerase chain reaction (RT-PCR) method for the detection of influenza viruses. Positive influenza samples with a cycle threshold (Ct) <30 were genetically and antigenically characterized. Results: 32 samples tested were found positive to influenza A with Ct <30. At CDC Atlanta, 28 out of 32 samples (88%) were tested positive for influenza A virus, including 26 seasonal influenza A viruses subtype H3N2 and 2 pandemic influenza A viruses subtype H1N1pdm 2009. The majority of influenza A(H3N2) viruses were antigenically related to the A/Switzerland/9715293/2013 vaccine virus, while two influenza A(H1N1)pdm09 isolates were antigenically characterized as A/California/07/2009-like. All A(H3N2) and A(H1N1)pdm09 virus isolates characterized were sensitive to oseltamivir and zanamivir. Conclusion: Two genetically distinct influenza subtypes were co-circulating in the DRCongo. Effective measures against influenza have been suggested. PMID- 29569653 TI - Cultural Theory of Risk as a Heuristic for Understanding Perceptions of Oil and Gas Development in Eastern Montana, USA. AB - This paper applies Douglas' cultural theory of risk to understand perceptions of risk associated with oil and gas development in eastern Montana. Based on the analysis of interviews with 36 rural residents, findings show the dominant perception of risk is most closely aligned with an Individualist worldview. Despite direct experience with oil or wastewater spills, most interviewees described spills as "no big deal", viewed nature as resilient, and felt that the economic benefits outweigh negative impacts. Cultural theory was a useful heuristic for understanding this dominant worldview, as well as identifying points of deviation. For example, interviewees discussed the benefits of landowner associations - a more Egalitarian approach to dealing with oil companies. Some landowners relied on external authorities (e.g., sheriff) when dealing with oil companies, revealing a Hierarchical approach to issues they face. Interviewees expressed frustration with the lack of enforcement of existing regulations, which can be interpreted as either support for - or indictment of - Hierarchical solutions. While the Individualist worldview is dominant, our qualitative analysis reveals the complex tensions at work among rural residents. The results suggest areas where policymakers, advocacy groups, and residents may find common ground to address potential environmental and health risks.

AB - Hepatocellular carcinoma (HCC) is a worldwide problem, with a high prevalence in nonindustrialized countries and a rising incidence in industrialized countries as well. Its close association with chronic liver diseases and liver cirrhosis represents a significant challenge in its treatment. A front-line systemic treatment for unresectable cases of HCC (sorafenib) was identified only in 2007. Following a decade of failed clinical trials with a wide range of drugs for second-line treatment, regorafenib proved its efficacy as a second-line treatment in 2016, when the randomized, placebo-controlled, phase III RESORCE trial demonstrated a meaningful increase in overall survival in the regorafenib treatment arm compared with the placebo arm (10.6 vs. 7.8 months). In this monograph we review the main preclinical and clinical findings in the trials assessing regorafenib for the treatment of HCC patients.

PMID- 29569659 TI - Controversies regarding the cardiovascular effects of testosterone replacement therapy in older men. AB - Testosterone (T) levels decline with the advancement of age and have been associated with increased incidence of cardiovascular disease (CVD). Indeed, several epidemiologic and prospective cohort studies have suggested that low T levels (lower tertile or quartile) are associated with increased incidence of CVD, type 2 diabetes mellitus (T2DM), obesity and dyslipidemia. In contrast, correction of low T levels with testosterone replacement therapy (TRT) is associated with a decrease in the incidence of CVD, T2DM and dyslipidemia as has been demonstrated by several randomized, controlled trials as well as prospective cohort studies. However, recent studies have shown that TRT is associated with an increased incidence of adverse CV events and these studies have created a great controversy regarding the CV benefits of TRT. In order to get a better perspective on the current status of TRT, a focused MEDLINE and Cochrane database search of the recent English language literature between 2010 and 2017 was conducted and 29 pertinent papers were retrieved. The studies reviewed could not definitely confirm the beneficial or adverse CV effects of TRT. Therefore, on the basis of the current stage of knowledge, older male subjects with low T levels could continue to receive TRT, but this decision should be discussed with their physicians.

Fifty-two new drugs and biologics reached their first markets worldwide in 2017. Seven of the new launches were first-in-class agents, meaning the first drug with a novel mechanism of action to be approved and launched anywhere in the world. In addition, 36 notable line extensions (i.e., new indications, new combinations and new formulations of previously marketed products) were introduced last year. The remaining 25 products discussed in this article were approved for the first time during the year just passed, but had not yet been launched as of December 31, 2017. The United States was the most active market for new drugs, and oncology was the most active therapeutic group. Information on these new arrivals is covered in depth in part I of our annual review of the pharma and biotech industry. PMID- 29569661 TI - Evaluation of the Fluoride Releasing and Recharging Abilities of Various Fissure Sealants. AB - PURPOSE: To evaluate the fluoride release from different fissure sealants sold mainly in non-Western countries via a curve-fitting method, and to investigate the ability of these materials to be recharged with fluoride. MATERIALS AND METHODS: Four different fissure sealants which the manufacturers claim to release F- were tested; glass-ionomer cement Argecem (AC), the composite resins Fisskhim (FK), Fissulight (FL), Helioseal F (HF). Helioseal (HS), a composite resin not declared to release F, was used as a negative control. Of each material, 10 disks 8.0 mm in diameter and 1.8 mm thick were produced. For fluoride measurements, a fluoride-ion specific electrode was used. On day 21, the specimens were recharged with fluoride by immersion in toothpaste slurry. Fluoride release was evaluated and statistically compared by fitting an exponential curve through the cumulative release values and statistically comparing curve parameters (t1/2, AUC and plateau value) among each other as well as before and after recharging. RESULTS: Two materials (AC and HF) released a considerable amount of F- in the first 3 weeks after sample production. Furthermore, the increase of F- release after F- recharge was statistically significant (p < 0.05) for the materials AC, FL and HF, but not for FK and HS. CONCLUSION: Fluoride release of Fisskhim and Fissulight was negligible, while Helioseal F and Argecem noticeably released fluoride and thus can enhance the caries preventive effect of fissure sealants. Comparing release curve parameters simplifies statistical procedures.

AB - Functional polymer/carbon nanotube (CNT) hybrid materials can serve as a good model for light harvesting systems based on CNTs. This paper presents the synthesis of block copolymer/CNT hybrids and the characterization of their photocurrent responses by both experimental and computational approaches. A series of functional diblock copolymers was synthesized by reversible addition fragmentation chain transfer polymerizations for the dispersion and functionalization of CNTs. The block copolymers contain photosensitizing ruthenium complexes and modified pyrene-based anchoring units. The photocurrent responses of the polymer/CNT hybrids were measured by photoconductive atomic force microscopy (PCAFM), from which the experimental data were analyzed by vigorous statistical models. The difference in photocurrent response among different hybrids was correlated to the conformations of the hybrids, which were elucidated by molecular dynamics simulations, and the electronic properties of polymers. The photoresponse of the block copolymer/CNT hybrids can be enhanced by introducing an electron-accepting block between the photosensitizing block and the CNT. We have demonstrated that the application of a rigorous statistical methodology can unravel the charge transport properties of these hybrid materials and provide general guidelines for the design of molecular light harvesting systems.

AB - Achieving fast and efficient quantum state transfer is a fundamental task in physics, chemistry and quantum information science. However, the successful implementation of the perfect quantum state transfer also requires robustness under practically inevitable perturbative defects. Here, we demonstrate how an optimal and robust quantum state transfer can be achieved by shaping the spectral phase of an ultrafast laser pulse in the framework of frequency domain quantum optimal control theory. Our numerical simulations of the single dibenzoterrylene molecule as well as in atomic rubidium show that optimal and robust quantum state transfer via spectral phase modulated laser pulses can be achieved by incorporating a filtering function of the frequency into the optimization algorithm, which in turn has potential applications for ultrafast robust control of photochemical reactions.

AB - A simple versatile method to form a nanofiber coating in situ on micrometer to millimeter-sized surfaces is developed. A fiber-filled porous sheet is designed by electrospinning a dense polymer solution on a patterned PET/aluminum alloy collector. By sticking the small area surface onto a fiber-filled porous sheet, a nanofiber-coated small area surface is obtained, which overcomes conventional nanofiber coating difficulties. PMID- 29569665 TI - The good, the bad, and the ugly - controlling singlet oxygen through design of photosensitizers and delivery systems for photodynamic therapy. AB - Singlet oxygen, although integral to photodynamic therapy, is notoriously uncontrollable, suffers from poor selectivity and has fast decomposition rates in biological media. Across the scientific community, there is a conscious effort to refine singlet oxygen interactions and initiate selective and controlled release to produce a consistent and reproducible therapeutic effect in target tissue. This perspective aims to provide an insight into the contemporary design principles behind photosensitizers and drug delivery systems that depend on a singlet oxygen response or controlled release. The discussion will be accompanied by in vitro and in vivo examples, in an attempt to highlight advancements in the field and future prospects for the more widespread application of photodynamic therapy. PMID- 29569666 TI - Circulating tumor DNA and liquid biopsy: opportunities, challenges, and recent advances in detection technologies. AB - Cell-free DNA (cfDNA) refers to short fragments of acellular nucleic acids detectable in almost all body fluids, including blood, and is involved in various physiological and pathological phenomena such as immunity, coagulation, aging, and cancer. In cancer patients, a fraction of hematogenous cfDNA originates from tumors, termed circulating tumor DNA (ctDNA), and may carry the same mutations and genetic alterations as those of a primary tumor. Thus, ctDNA potentially provides an opportunity for noninvasive assessment of cancer. Recent advances in ctDNA analysis methods will potentially lead to the development of a liquid biopsy tool for the diagnosis, prognosis, therapy response monitoring, and tracking the rise of new mutant sub-clones in cancer patients. Over the past few decades, cancer-specific mutations in ctDNA have been detected using a variety of untargeted methods such as digital karyotyping, personalized analysis of rearranged ends (PARE), whole-genome sequencing of ctDNA, and targeted approaches such as conventional and digital PCR-based methods and deep sequencing-based technologies. More recently, several chip-based electrochemical sensors have been developed for the analysis of ctDNA in patient samples. This paper aims to comprehensively review the diagnostic, prognostic, and predictive potential of ctDNA as a minimally invasive liquid biopsy for cancer patients. We also present an overview of current advances in the analytical sensitivity and accuracy of ctDNA analysis methods as well as biological and technical challenges, which need to be resolved for the integration of ctDNA analysis into routine clinical practice. PMID- 29569667 TI - A 3D-printed flow distributor with uniform flow rate control for multi-stacked microfluidic systems. AB - In the scale-up of chemical production in a microfluidic system, it is challenging to prevent flow maldistribution from a single inlet into stacked multiple microchannel exits. In the present study, a compact flow distributor equipped with a fluidic damper is developed by computational fluid dynamics (CFD) along with experimental validation. A microfluidic flow distributor, which is equipped with an optimized fluidic damper and consists of 25 exit channels, is fabricated as an integrated body using a digital light processing (DLP) type 3D printer. The 3D printed flow distributor with a CFD-optimized fluidic damper is found to achieve a low maldistribution factor (MF) of 2.2% for the average flow rate over 25 exit channels while inducing only a minor increment (<6%) in the pressure drop. A generalized manual is proposed for the design of optimal flow distributors with different scale-up dimensions. Using the manual, an optimal flow distributor with 625 stacked microchannels with a MF of only 1.2% is successfully designed. It is expected that the design manual and the rapid printing platform will allow the efficient development of multi-channel stacked micro-devices such as those in drug delivery and energy conversion systems where equidistribution of fluid flow is highly demanded. PMID- 29569668 TI - Theranostic micelles based on upconversion nanoparticles for dual-modality imaging and photodynamic therapy in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is frequently metastatic once diagnosed and less likely to respond to curative surgery, emphasizing the need for the development of more sensitive and effective diagnostic and therapeutic strategies. Epithelial cell adhesion molecule (EpCAM) is deemed as the biomarker of cancer stem cells (CSCs), which are mainly responsible for the recurrence, metastasis and prognosis of HCC. In this study, we discuss the use of mitoxantrone (MX), an antitumor drug and a photosensitizer, for designing upconversion nanoparticle-based micelles grafted with the anti-EpCAM antibody, for dual-modality magnetic resonance/upconversion luminescence (MR/UCL)-guided synergetic chemotherapy and photodynamic therapy (PDT). The obtained micelles exhibit good biocompatibility, high specificity to HCC cells and superior fluorescent/magnetic properties in vitro. In vivo results demonstrate that the targeted micelles exhibited much better MR/UCL imaging qualities compared to the nontargeted micelles after the intravenous injection. More importantly, PEGylated UCNP micelles loaded with MX and grafted with anti-EpCAM antibody, denoted as anti-EpCAM-UPGs-MX, showcased the most effective synergetic antitumor efficacy compared with other treatment groups both in vitro and vivo. The remarkable antitumor effect, coupled with superior simultaneous dual-modality MR/UCL imaging as well as good biocompatibility and negligible toxicity, makes the UPG micelles promising for future translational research in HCC diagnosis and therapy. PMID- 29569670 TI - Building expanded structures from tetrahedral DNA branching elements, RNA and TMV protein. AB - By combining both chemical and enzymatic ligation with procedures guiding the self-assembly of nanotubular tobacco mosaic virus (TMV)-like particles (TLPs), novel nucleoprotein structures based on DNA-terminated branching elements, RNA scaffolds and TMV coat protein (CP) are made accessible. Tetrahedral tetrakis(hydroxybiphenyl)adamantane cores with four 5'-phosphorylated dinucleotide arms were coupled to DNA linkers by chemical ligation. The resulting three-dimensional (3D) branching elements were enzymatically ligated to the 3' termini of RNA scaffolds either prior to or after the RNAs' incorporation into TLPs. Thus, architectures with interconnected nanotube domains in two different length classes were generated, each containing 70 CP subunits per 10 nm length. Short TMV origin-of-assembly-containing RNA scaffolds ligated to the DNA allowed the growth of protein-coated 34 nm tubes on the terminal RNA strands in situ. Alternatively, 290 nm pre-fabricated tubes with accessible RNA 3' termini, attained by DNA blocking elements hybridized to the RNAs, were ligated with the branched cores. Both approaches resulted in four-armed nanoobjects, demonstrating a so far unique combination of organic synthesis of branching elements, enzymatic modifications, nucleic acid-based scaffolding and RNA-guided and DNA-controlled assembly of tubular RNA-encapsidating protein domains, yielding a novel class of 3D nucleoprotein architectures with polyvalent protein elements. In the long term, the production route might give rise to supramolecular systems with complex functionalities, installed via the orthogonal coupling of effector molecules to TLP domains. PMID- 29569669 TI - Carbon chain shape selectivity by the mouse olfactory receptor OR-I7. AB - The rodent OR-I7 is an olfactory receptor exemplar activated by aliphatic aldehydes such as octanal. Normal alkanals shorter than heptanal bind OR-I7 without activating it and hence function as antagonists in vitro. We report a series of aldehydes designed to probe the structural requirements for aliphatic ligand chains too short to meet the minimum approximate 6.9 A length requirement for receptor activation. Experiments using recombinant mouse OR-I7 expressed in heterologous cells show that in the context of short aldehyde antagonists, OR-I7 prefers binding aliphatic chains without branches, though a single methyl on carbon-3 is permitted. The receptor can accommodate a surprisingly large number of carbons (e.g. ten in adamantyl) as long as the carbons are part of a conformationally constrained ring system. A rhodopsin-based homology model of mouse OR-I7 docked with the new antagonists suggests that small alkyl branches on the alkyl chain sterically interfere with the hydrophobic residues lining the binding site, but branch carbons can be accommodated when tied back into a compact ring system like the adamantyl and bicyclo[2.2.2]octyl systems. PMID- 29569671 TI - Spontaneous rolling-up and assembly of graphene designed by using defects. AB - The inverse Stone-Wales defect is a typical defect in graphene, which causes local bumps and local deformation in graphene sheets. Our molecular dynamics simulations show that the spontaneous rolling up of graphene sheets can be induced by orderly distributed inverse Stone-Wales defect bumps, when defective graphene is cut into small strips. This spontaneous process is mainly dominated by the defect density and tailored graphene size. When the tailored length is longer than the upper threshold length, graphene sews up as a curly one dimensional structure: heart-shaped nanotube. For medium length graphene (the length is in between the lower threshold value and upper threshold value), the results reveal that graphene finally curls into a completely or incompletely stitched nanotube similar to a cylindrical shell. This spontaneous process is produced by a high-frequency damped vibration accompanied by elastic and viscoelastic deformation in defective graphene. Thus, the properties of vibration are further investigated for graphene that has the tailored length shorter than the lower threshold length. This kind of graphene gradually forms a curved nanoribbon rather than a nanotube. It is also found that the bending rigidity of defective graphene is larger than that of pristine graphene. PMID- 29569672 TI - Recent advances in the nanoengineering of electrocatalysts for CO2 reduction. AB - Emissions of CO2 from fossil fuel combustion and industrial processes have been regarded as the dominant cause of global warming. Electrochemical CO2 reduction (ECR), ideally in aqueous media, could potentially solve this problem by the storage of energy from renewable sources in the form of chemical energy in fuels or value-added chemicals in a sustainable manner. However, because of the sluggish reaction kinetics of the ECR, efficient, selective, and durable electrocatalysts are required to increase the rate this reaction. Despite considerable progress in using bulk metallic electrodes for catalyzing the ECR, greater efforts are still needed to tackle this grand challenge. In this Review, we highlight recent progress in using nanoengineering strategies to promote the electrocatalysts for the ECR. Through these approaches, considerable improvements in catalytic performance have been achieved. An outlook of future developments in applying and optimizing these strategies is also proposed. PMID- 29569673 TI - Collective motion of active Brownian particles with polar alignment. AB - We present a comprehensive computational study of the collective behavior emerging from the competition between self-propulsion, excluded volume interactions and velocity-alignment in a two-dimensional model of active particles. We consider an extension of the active brownian particles model where the self-propulsion direction of the particles aligns with the one of their neighbors. We analyze the onset of collective motion (flocking) in a low-density regime (10% surface area) and show that it is mainly controlled by the strength of velocity-alignment interactions: the competition between self-propulsion and crowding effects plays a minor role in the emergence of flocking. However, above the flocking threshold, the system presents a richer pattern formation scenario than analogous models without alignment interactions (active brownian particles) or excluded volume effects (Vicsek-like models). Depending on the parameter regime, the structure of the system is characterized by either a broad distribution of finite-sized polar clusters or the presence of an amorphous, highly fluctuating, large-scale traveling structure which can take a lane-like or band-like form (and usually a hybrid structure which is halfway in between both). We establish a phase diagram that summarizes collective behavior of polar active brownian particles and propose a generic mechanism to describe the complexity of the large-scale structures observed in systems of repulsive self-propelled particles. PMID- 29569674 TI - A distinctive transformation based diversity oriented synthesis of small ring carbocycles and heterocycles from biocatalytically derived enantiopure alpha substituted-beta-hydroxyesters. AB - A series of structurally novel small ring carbocyclic and heterocyclic molecules were accessed in an enantiopure fashion. The starting materials, alpha substituted-beta-hydroxyesters, were achieved through the biocatalytic dynamic kinetic resolution of parent beta-ketoesters in an excellent enantio and diastereocontrolled way. The active functional groups present in the starting precursor, were then tuned sequentially through certain key transformations (functional group interconversions; FGIs) to yield several small molecular scaffolds in a diverse way. Specific transformations such as halocyclization, ene yne metathesis, dipolar cycloaddition, Mitsunobu cyclization, ring closing metathesis and Pauson-Khand reactions were mainly applied to generate the diversity. PMID- 29569675 TI - Touching the theoretical capacity: synthesizing cubic LiTi2(PO4)3/C nanocomposites for high-performance lithium-ion battery. AB - A cubic LiTi2(PO4)3/C composite is successfully prepared via a simple solvothermal method and further glucose-pyrolysis treatment. The as-fabricated LTP/C material delivers an ultra-high reversible capacity of 144 mA h g-1 at 0.2C rate, which is the highest ever reported, and shows considerable performance improvement compared with before. Combining this with the stable cycling performance and high rate capability, such material has a promising future in practical application. PMID- 29569676 TI - A theoretical study on the oxidation of alkenes to aldehydes catalyzed by ruthenium porphyrins using O2 as the sole oxidant. AB - Density functional theory (DFT) calculations were used to study the ruthenium porphyrin-catalyzed oxidation of styrene to generate an aldehyde. The results indicate that two reactive oxidants, dioxoruthenium and monooxoruthenium-superoxo porphyrins, participate in the catalytic oxidation. In the mechanism, the resultant monooxoruthenium porphyrin acts in the tandem epoxide isomerization (E I) to selectively yield an aldehyde and generate a dioxoruthenium porphyrin, thereby triggering new oxidation reaction cycles. In this calculation, several key elements responsible for the observed oxidative ability have been established by using Frontier molecular orbital (FMO) theory, natural bond orbital (NBO) analysis, etc., which include the reaction energy, the spin exchange effect, the spin-state conversion process, and the energy level of the lowest unoccupied molecular orbitals (LUMOs) of the reactive oxidants. The comparative oxidative abilities of the ruthenium-oxo/superoxo compounds with different axial ligands are also investigated. The results suggest that the ruthenium-oxo/superoxo species featuring a chlorine axial ligand is more reactive than that substituted with oxygen. This tuneable reactivity can be understood when considering the different electronic characters of the two ligands and the effective atomic number rule (EAN). PMID- 29569677 TI - Monte Carlo simulations of weak polyelectrolyte microgels: pH-dependence of conformation and ionization. AB - In this study, we investigated the effect of pH on single weak acidic polyelectrolyte microgels under salt-free conditions with (i) varying microgel concentration, (ii) varying content of acidic groups and (iii) different crosslinking densities using Monte Carlo simulations under explicit consideration of the protonation/deprotonation reaction. We assessed both global properties, such as the degree of ionization, the degree of swelling and the counterion distribution, and local properties such as the radial network ionization profile and the ionization along the polymer chains as a function of pH. We found a pronounced suppression of the pH-dependent ionization of the microgels, as compared to the ideal titration behavior and a shift of the titration curve to a higher pH originating in the proximity of acidic groups in the microgel. In contrast to macroscopic gels, counterions can leave the microgel, resulting in an effective charge of the network, which hinders the ionization. A decreasing microgel concentration leads to an increased effective charge of the microgel and a more pronounced shift of the titration curve. The number of acidic groups showed only a weak effect on the ionization behavior of the microgels. For two different microgels with different crosslinking densities, similar scaling of the gel size was observed. A distinct transition from an uncharged and unswollen to a highly charged and expanded polymer network was observed for all investigated microgels. The degree of swelling mainly depends on the degree of ionization. An inhomogeneous distribution of the degree of ionization along the radial profile of the microgel was found.

AB - Temperature-responsive cell culture substrates reported here can be dynamically programmed to induce bulk softening and surface roughness changes in the presence of living cells. Alterations in hepatocellular function following temporally controlled substrate softening depend on the extent of stiff mechanical priming prior to user-induced material transition. PMID- 29569679 TI - The success of endotracheal intubation with a modified laryngoscope using night vision goggles. AB - BACKGROUND: Endotracheal intubation (ETI) procedure in the combat area differs from prehospital trauma life support procedures because of the danger of gunfire and the dark environment. We aimed to determine the success, difficulty degree, and duration of ETI procedures with a classical laryngoscope (CL) in a bright room and with a modified laryngoscope (ML) model in a dark room. METHODS: All interventions were performed by a combatant medical staff of 10 members. We developed an ML model to obtain a tool that can be used in combination with night vision goggles (NVGs) to perform ETI at night. The procedures were performed using a CL with the naked eye in a bright room and using a ML with NVGs in a dark room. The ETI procedure that used the ML was performed by engaging and locking the blade on the handle either in the mouth (ML-IM) or outside of the mouth (ML OM). RESULTS: The mean completion times for the ETI procedures, namely Day-CL, ML OM+NVG, and ML-IM+NVG, performed by the operators were 14.46, 26.9, and 32.38 s, respectively. The ML-OM+NVG and ML-IM+NVG procedures were significantly longer than the Day-CL procedure (p<0.05). The ML-IM+NVG procedure was significantly longer than the ML-OM+NVG procedure (p<0.05). All ETI procedures were found to be 100% successful. The Day-CL procedure was easier than the ML-OM+NVG and ML-IM+NVG procedures (p>0.05). CONCLUSION: The ETI procedure is applicable using NVGs in dark conditions on the battlefield. Medical interventions performed using NVGs in the dark should be a part of the basic training provided in tactical emergency medicine. PMID- 29569680 TI - Successful non-operative management of blunt abdominal trauma in highly selective cases: A safe and effective choice. AB - BACKGROUND: The non-operative management (NOM) of abdominal injuries has gained wide acceptance over the last few decades. The present study evaluated the efficacy of NOM in blunt abdominal trauma (BAT) at a regional Hellenic hospital. METHODS: We analyzed the results of a pre-decided treatment protocol, which was applied to all patients hospitalized for BAT, from 2008 to 2015. The protocol proposed NOM in hemodynamically stable patients with no signs of peritonitis. The demographic characteristics, type of injury, injured organ(s), type of management (operative vs. non-operative), Injury Severity Score (ISS), morbidity, mortality rates, and health costs were evaluated. RESULTS: One hundred and forty-six patients hospitalized for BAT at our department were included. Among them, 49 were operated and 97 were subjected to NOM. Although ISS was significantly higher in the surgical group, the severity of injuries in liver, spleen, and kidneys was not different between the two groups. Surprisingly, no case subjected to NOM required a conversion to operative management, which may probably be because of the strict inclusion criteria for NOM. CONCLUSION: Patients with hemodynamic stability and normal physical examination may be non-operatively treated, independent of the grade of injury, in highly selective cases. ISS score is an independent risk factor for surgical treatment. PMID- 29569681 TI - Can serum soluble urokinase plasminogen activator receptor be an effective marker in the diagnosis of appendicitis and differentiation of complicated cases? AB - BACKGROUND: Soluble urokinase plasminogen activator receptor (suPAR) is a new biomarker of inflammation level. The aim of the study was to evaluate whether suPAR levels could be useful to detect acute appendicitis and to differentiate uncomplicated appendicitis (UA) from complicated appendicitis (CA). METHODS: We prospectively studied 105 patients consisting of 40 UA cases, 40 CA cases, and 25 control patients. Blood samples were collected to measure suPAR level, C-reactive protein level, leukocyte counts, neutrophil counts, and neutrophil percentages preoperatively. RESULTS: Median values of suPAR level, C-reactive protein level, leukocyte counts, neutrophil counts, and neutrophil percentages in UA and CA were significantly higher than control patients. suPAR levels of the UA and CA groups showed a statistically significant difference (p=0.016). CONCLUSION: The current study demonstrated that serum suPAR concentrations can be helpful in differentiating CA from UA and in diagnosing acute appendicitis. PMID- 29569682 TI - Features and treatment of gas-forming synergistic necrotizing cellulitis: a nine year retrospective study. AB - BACKGROUND: As many doctors know little about gas-forming synergistic necrotizing cellulitis, we retrospectively explored it in our study. METHODS: Totally, 30 patients diagnosed with gas-forming synergistic necrotizing cellulitis between November 2006 and September 2015 were included. They were divided into two groups: open drainage group (19 patients) and aggressive debridement group (11 patients). Retrospectively analyzed data comprised demographic characteristics, APACHE II scores, pathogen culture results, bleeding amount during the operation, white blood cell count, length of hospital stay and recovery. RESULTS: The mortality rate was 26% in the open drainage group and 73% in the aggressive debridement group (p=0.023). There was no statistical difference in the APACHE II score before treatment between the open drainageand aggressive debridement groups (16.6+/-4.5 vs 18.1+/-7.5, p=0.511). The APACHE II score was significantly higher after treatment in the aggressive debridement group (14.2+/-5.8 score vs 20.1+/ 9.1, p=0.038). There were no statistical differences in the white blood count cell before and after treatment (13.49 * 109+/-5.05*109 cells/L vs 17.46*109+/ 6.94*109 cells/L, p=0.082; 10.37*109+/-3.54*109 cells/L vs 15.47*109 +/-7.51*109 cells/L, p=0.055; respectively). The bleeding amount during the operation was significantly more in the aggressive debridement group (315+/-112 ml vs 105+/-45 ml, p<0.001. CONCLUSION: For treating gas-forming synergistic necrotizing cellulitis, performing open drainage as early as possible isthe most important procedure after admission. PMID- 29569683 TI - Computed tomography use in minor head injury: attitudes and practices of emergency physicians, neurosurgeons, and radiologists in Turkey. AB - BACKGROUND: We aimed to determine the attitudes and practices of emergency physicians (EPs), neurosurgeons, and radiologists in Turkey regarding computed tomography (CT) use for adults with minor head injury (MHI). METHODS: This cross sectional study was conducted between August 2015 and October 2016 after obtaining the approval of the institutional ethical committee. The purpose of this study was disclosed to the participants prior to beginning the survey. The study was performed conducting a questionnaire via e-mail on three groups of participants including EPs, neurosurgeons, and radiologists. Participants comprised academic staff at university hospitals as well as department chiefs, specialists, and residents working at university, government, and private hospitals, all of whom are in charge of evaluating MHI patients. RESULTS: A total of 607 participants including 201 (33.1%) EPs, 179 (29.5%) neurosurgeons, and 227 (37.4%) radiologists responded to the survey; 31% of the participants reported awareness and 27.3% reported use of head CT rules in MHI. Awareness and use of the rules were most prominent in EPs group, while the lowest rates were observed in radiologists group (p<0.01). The leading factors inhibiting the use of head CT rules in MHI stated by EPs were medicolegal anxiety (73.6%), expectations of patients and/or patient relatives (72.6%), and time constraints (44.3%). The leading factors stated by neurosurgeons were medicolegal anxiety (60.9%) and expectations of patient and/or patient relatives (46.4%); "not being consulted in the decision-making process to obtain CT in MHI" (65.6%) and medicolegal anxiety (49.8%) were the leading factors stated by radiologists. CONCLUSION: The results of our study show that many physicians in Turkey do not have favorable attitudes regarding head CT rules in MHI. Medicolegal anxiety, expectations of patient and/or patient relatives, time constraints, wide availability of CT, and lack of adequate education on radiation protection or on patient dose from imaging are the common reasons for this practice pattern. PMID- 29569684 TI - Media-based clinical research on selfie-related injuries and deaths. AB - BACKGROUND: The incidence of taking selfies and sharing them on social media as well as selfie-related behaviors is increasing, particularly among young people, possible leading to selfie-related trauma. Therefore, we performed this clinical study to draw attention to selfie-related injuries and deaths. METHODS: We analyzed 159 selfie victims from 111 events or accidents, which were reported in the media sources. We evaluated vital results, demography, rhythmicity, preferences, event or accident types, selfie-related risk factors, affected body regions of victims with causes of injury, and death. RESULTS: We found that the majority of selfie victims were students. Selfie-related injuries and deaths were reported most frequently in India, the US, and Russia. The most preferred site of taking selfies was the edge of the cliff. The most frequently reported event or accident type was falling from a height. Mostly multiple body parts were affected in selfie-related injuries and deaths. The most frequent causes of selfie-related deaths were multitrauma and drowning. CONCLUSION: Selfie-related injuries and deaths have increased in the past years. Particularly, teenagers and young adults are at high risk for selfie-related traumas and deaths; therefore, drastic measures should be taken to reduce their incidence. PMID- 29569685 TI - Importance of knowledge of the management of traumatic dental injuries in emergency departments. AB - BACKGROUND: Hospital emergency departments (EDs) are confronted with managing dental emergencies of both traumatic and non-traumatic origin. However, the literature suggests inadequate knowledge of the management of traumatic dental injuries (TDIs) among medical professionals. The aim of this study was to investigate the knowledge and attitudes regarding management of TDIs among Istanbul ED physicians. METHODS: Surveys were distributed to emergency departments (ED) directors and their physicians. The survey contained questions about their characteristics and tested their knowledge of managing dental trauma. RESULTS: A total of 126 surveys (13 ED directors and 113 physicians) were returned and included in the analysis. ED physician's knowledge of the appropriate management of crown fractures and avulsion was generally good (p=0.221), but poor for luxation injuries (p=0.0001). Physicians were more likely to have a better knowledge about permanent teeth than about primary teeth (p=0.027). CONCLUSION: Education, monitoring, improved availability of resources, and disciplinary measures in cases of poor compliance are necessary to improve TDI management in hospitals, especially among physicians. PMID- 29569686 TI - Spiked railing penetration that causes injuries in the upper extremities of children. AB - BACKGROUND: Children have a curiosity for climbing walls, stairs, and railings and have an increased risk of falling. Here, we report our experience with railings causing injuries by penetrating the upper extremities, and aim to call attention to spiked railing injuries in children. METHODS: We report on five children with a mean age of 8.8. All of the children were male. The penetrating railing parts were removed in a surgical room. RESULTS: The injured structures repaired immediately were as follows: flexor digitorum profundus tendon, A4 pulley, volar plate of the distal interphalangeal joint, radial digital nerve, ulnar digital artery, and radial digital artery. CONCLUSION: Spiked railings can lead to significant injury that requires further exploration. Boys particularly are at risk, and parents should be alert regarding these type of injuries. We recommend a standard regulation for fence erection, and we wish to warn owners of this type of fence regarding probable legal sanctions. PMID- 29569687 TI - Mortality in Code Blue; can APACHE II and PRISM scores be used as markers for prognostication? AB - BACKGROUND: Code blue (CB) is an emergency call system developed to respond to cardiac and respiratory arrest in hospitals. However, in literature, no scoring system has been reported that can predict mortality in CB procedures. In this study, we aimed to investigate the effectiveness of estimated APACHE II and PRISM scores in the prediction of mortality in patients assessed using CB to retrospectively analyze CB calls. METHODS: We retrospectively examined 1195 patients who were evaluated by the CB team at our hospital between 2009 and 2013. The demographic data of the patients, diagnosis and relevant de-partments, reasons for CB, cardiopulmonary resuscitation duration, mortality calculated from the APACHE II and PRISM scores, and the actual mortality rates were retrospectively record-ed from CB notification forms and the hospital database. RESULTS: In all age groups, there was a significant difference between actual mortality rate and the expected mortality rate as estimated using APACHE II and PRISM scores in CB calls (p<0.05). The actual mortality rate was significantly lower than the expected mortality. CONCLUSION: APACHE and PRISM scores with the available parameters will not help predict mortality in CB procedures. Therefore, novels scoring systems using different parameters are needed. PMID- 29569688 TI - Surgical treatment of displaced intraarticular calcaneus fractures using anatomical lateral frame plate. AB - BACKGROUND: The present study evaluated the results obtained from the anatomical lateral frame plate treatment of displaced intraarticular calcaneus fractures. METHODS: Overall, 14 displaced intraarticular fractures of 13 patients (3 females, 10 males; Mean age, 37.5 years) were included in the present study. Surgery was performed using widened lateral approach and supported by auto grafts following joint line reduction in all patients. They were then fixated by anatomical lateral frame plate. All the joints were stabilized by casting after the operation. All patients were prescribed controlled and full weight bearing at 6-8th and 12th weeks, respectively. RESULTS: Mean follow-up of patients was 28 months. The fractures were classified according to Sanders system. Clinical scoring of the patients was performed according to American Orthopaedic Foot and Ankle Society, Creighton-Nebraska, and Maryland systems. According to these systems, the mean scores of the patients were 83.7, 75.7, and 88.5 respectively. CONCLUSION: In the present study, we have defined the results of anatomical lateral frame plate treatment in patients with displaced intraarticular calcaneus fractures. We have obtained clinically and radiologically satisfactory results with the anatomical compatibility of plate to the lateral surface of the calcaneus.

AB - BACKGROUND: To investigate the outcomes of patients undergoing open reduction and internal fixation with olecranon osteotomy due to AO type13C fractures of the distal humerus. METHODS: Data of 39 patients (mean age, 44.7 years; males, 56.4%) undergoing surgery with the diagnosis of AO type 13C distal humeral fractures were retrospectively evaluated. Patients' demographic characteristics, medical history, and radiological and functional outcomes were recorded. The patients were evaluated at the final follow-up according to the Mayo Elbow Performance Index (MEPI). RESULTS: The mean degrees of flexion and extension loss were 102.2 degrees (range, 60-120 degrees) and 11.4 degrees (range, 0-25 degrees), respectively, at the final follow-up. According to the MEPI score, outcomes were excellent in seven, good in 12, fair in 13, and poor in seven patients. All patients achieved a radiological union of the fracture site within the first postoperative six months. It was found that the loss of extension was more severe, the range of flexion was decreased, and the mean MEPI score was lower in the patients with type C3 fractures than in those with type C1 and type C2 fractures. No significant difference was determined between fixation techniques (tension band vs. cannulated screw) regarding the functional outcomes. CONCLUSION: Our results revealed better prognosis in AO type C1 and type C2 fractures than in AO type C3 fractures and no different effects of two fixation techniques in olecranon osteotomy on the outcomes. PMID- 29569690 TI - Fixation of rotationally unstable extracapsular proximal femoral fractures. AB - BACKGROUND: It was thought that the AO types A1.2 and A1.3 fractures are rotationally stable; however, it revealed instability when fixed using the dynamic hip screw. Therefore, we hypothesized that these fractures should be treated as rotationally unstable. METHODS: A series of 83 fractures of the AO types A1, A2, and B2.1 were treated using dynamic hip screw with derotation screw (DHS/DRS) composite and then prospectively followed for 24 months. Adequacy of reduction and fixation were immediately assessed after surgery, and fracture collapse was assessed at six months or when fractures healed. To investigate the feasibility of our hypothesis, fractures were classified into two groups: 1) the inevitably unstable group (IUG) included the AO types A1.1, A2.1, A2.2, A2.3, and B2.1 fractures and 2) the potentially unstable group (PUG) included the AO types A1.2 and A1.3 fractures. The results were statistically analyzed. RESULTS: Adequate reduction was achieved in 77 and adequate fixation in 71 fractures. All fractures healed in a mean time of 13.5 weeks, and the amount of the fracture collapse averaged 5.8 mm. Equalization of the lower limbs was achieved in 66 patients, and hip motion range equalized the healthy contralateral in 80 patients. Re-operation was performed in one case with AO type A1.2. Comparison of IUG and PUG using the outcomes revealed insignificant differences. CONCLUSION: Using the DHS/DRS composite, anatomical features of the proximal femoral end were restored and maintained during the follow-up period. Insignificant differences between outcomes of IGU and PGU render the addition of the AO types A1.2 and A1.3 to the rotationally unstable fractures reasonable. PMID- 29569691 TI - Traumatic evisceration after blunt trauma in a 20-month-old boy. AB - Blunt traumatic evisceration is extremely rare. We describe the case of a 20 month-old boy with stomach and small and large intestine evisceration after blunt trauma. Immediate laparotomy and surgical repair were performed. There was no injury, other than a small hole in the mesentery. The bowels were drained into the abdominal cavity, and the skin was closed. The patient recovered well. PMID- 29569692 TI - Intestinal nonrotation and left-sided perforated appendicitis. AB - Acute appendicitis is the most common cause of acute abdominal pain, requiring emergency surgery. Approximately one third of cases have pain unexcepted location due to its various anatomical location. Acute appendicitis is a very rare cause of left lower quadrant pain; if it occurs, a few congenital anomalies should be considered such as Situs Inversus totalis and Midgut Malrotation (MM). MM is a rare congenital anomaly; it occurs due to error in process of rotation or fixation of intestines around the superior mesenteric vessels and it refers to nonrotation or incomplete rotation of intestines. Here we report a case who presented with left lower abdominal pain and was diagnosed with acute perforated appendicitis with intestinal nonrotation. Clinicians should be aware that intestinal nonrotation may be presented with left lower quadrant pain and complicated by acute appendicitis. PMID- 29569693 TI - Acute arterial occlusion due to vascular closure device: A report of two cases. AB - Vascular closure devices are frequently used after percutaneous arterial interventions to achieve hemostasis at the puncture site and facilitate early ambulation. Occasionally, complications have been reported with closure devices, such as hematoma, infection, arteriovenous fistula, pseudoaneurysm, and ischemia. This is a report of 2 cases of severe, acute-onset arterial occlusion and critical limb ischemia, one of which occurred in the upper limb following the use of a vascular closure device, and the required surgical treatment. PMID- 29569695 TI - Pneumothorax after a ventriculoperitoneal shunt placement: case report and review of the literature. AB - An 82-year-old woman underwent a ventriculoperitoneal (VP) shunt placement to treat hydrocephalus secondary to a right thalamic intracerebral hemorrhage. Pneumothorax and subcutaneous emphysema was noted 2 hours later. No respiratory distress was noted. A chest computed tomography scan revealed that the shunt tube had penetrated the diaphragm and entered the pleural space. The shunt tube penetrated the lung parenchyma and exited the pleural space via the third intercostal space. She underwent chest drainage and VP shunt reposition. The VP shunt functioned properly and no infection was noted. Bending the shunt passer slightly and keeping the passer tip pointed upward and palpable during its advancement may prevent this complication. It may be acceptable to leave the shunt tube in place after chest drainage for pneumothorax. PMID- 29569694 TI - Oxytocin for preventing injury due to testicular torsion/detorsion in rats. AB - BACKGROUND: We aimed to demonstrate the effectiveness of oxytocin on the testes for treating ischemia-reperfusion injury. METHODS: A total of 24 male Wistar albino rats weighing 250-320 g were used. The rats were randomized into three groups of eight rats. Group 1 was assessed as the control group. In Group 2 rats, testicular torsion was first performed, followed by testicular detorsion to induce reperfusion injury. In Group 3, following testicular torsion and detorsion, oxytocin was administered before inducing reperfusion. Testicular tissues were histologically evaluated, spermatogenic parameters were assessed using the Johnsen scoring system, and the mean Johnsen score was calculated. RESULTS: Histological tests revealed significantly different results between the testicular torsion group and the oxytocin-treated torsion and control groups as well as between the oxytocin-treated torsion group and the control and testicular torsion groups (p=0.010 and 0.012, respectively). Biochemical test results revealed that superoxide dismutase and glutathione peroxidase levels were significantly lower in Group 2 than in Group 1 (p=0.007 and 0.007, respectively). Malondialdehyde and nitric oxide levels were significantly lower in Group 3 than in Group 2 (p=0.017 and 0.014, respectively). CONCLUSION: These results indicate that oxytocin can be considered as an alternative agent for treating testicular torsion in clinical practice to minimize tissue damage. PMID- 29569696 TI - Association of rs2228570 Polymorphism of Vitamin D Receptor Gene with Lumbar Degenerative Disc Disease. AB - AIM: Lumbar degenerative disc disease (LDDD) is the most common cause of lower back pain (LBP) and sciatica. The vitamin D receptor (VDR) gene, which is located on chromosome 12 (12q12-q14), was the first gene reported to be potentially related to intervertebral degenerative disc disease risks. We conducted a case control study of a Turkish population and investigated the association between the VDR gene rs2228570 FokI polymorphism and the development of LDDD. MATERIAL AND METHODS: This was a prospective case-control study that included 45 patients with LDDD and 49 healthy individuals (control group). The clinical investigations of the LDDD patients consisted of neurological examinations, lumbar magnetic resonance imaging studies, visual analog scale (VAS) scores, and Oswestry Disability Index scores. The VDR gene rs2228570 FokI polymorphism was analyzed via a real-time polymerase chain reaction. RESULTS: We found that the individuals with the VDR GG genotype had a significantly increased risk of LDDD, while those with the AG genotype had a significantly decreased risk. In addition, the A allele may have a protective effect against LDDD in the Turkish population. Moreover, the VAS pain results showed that the GG genotype had a significantly higher score than the others. CONCLUSION: Our results suggested that the VDR rs2228570 AG genotype was at a decreased risk and the GG genotype was at an increased risk of LDDD in the Turkish population. Since genetic polymorphisms often show ethnic differences, further functional studies are needed to evaluate the genotype and phenotype correlations in large cohorts of various ethnicities.

PMID- 29569698 TI - Expression of microRNA-145, OCT4, and SOX2 in double primary endometrioid endometrial and ovarian carcinomas. AB - Double primary endometrioid endometrial and ovarian carcinomas (DPEEOCs) are the most common multiple gynecological carcinomas. In recent years, gene sequential comparison analysis has strongly supported the opinion that sporadic double endometrioid endometrial and ovarian cancers (DEEOCs) are clonally related in both primary and metastatic tumors. In order to find more clonal evidence for DPEEOC, we investigated cancer stem cells (CSCs). SOX2 and OCT4 are two common factors in CSCs. MicroRNA (miRNA)-145, a small non-coding RNA, has effects in regulating gene expression and tumorigenesis in CSCs. The aim of this study was to assess the involvements of SOX2, OCT4, and miRNA-145 in the tumorigenesis of DPEEOCs. In our study, twenty DPEEOC patients were chosen. Metastatic DEEOCs and normal endometrial and ovarian tissues were also included. The expression of miRNA-145 was detected by real-time quantitative PCR. Immunohistochemical staining was used to measure the expression of OCT4 and SOX2. The results showed that miRNA-145 expression was lower in DPEEOC endometrial tissues and higher in DPEEOC ovarian tissues compared to the corresponding normal tissues. Both SOX2 and OCT4 were over-expressed in cancer tissues compared with that in normal tissues. MiRNA-145, SOX2, and OCT4 were expressed at similar levels in two cancer sites of a given DPEEOC or metastatic DEEOC sample. Besides, metastatic DEEOC sections expressed a higher level of SOX2 and OCT4 compared to the corresponding DPEEOC tissues. Together, these results support the clonality of DPEEOCs. Moreover, SOX2 and OCT4 may have some implication in DPEEOC and metastatic DEEOC diagnosis. PMID- 29569699 TI - The posterior epidural ligament in the thoracic region: a cadaveric and histological study. AB - The existence of posterior epidural ligaments (PEL) has been established in the lumbar region, but they have hitherto not been shown to exist in the thoracic vertebral column. Their identification is of clinical significance in respect to incidental durotomy and the circulation of cerebro-spinal fluid. Fourteen thoracic spine sections were dissected by cutting through the intervertebral disc and separating the ligamentum flavum from the vertebra above. The dural sheath was gently retracted anteriorly to identify macroscopic connections between the ligamentum flavum and the dura. Macroscopic connections observed were dissected out, retaining some dural sheath and ligamentum flavum. Histological staining with haematoxylin and eosin (H&E) and Miller's elastin stain was used to investigate cellular connections. Thoracic PELs were positively identified in five of the fourteen cadavers (35.7%). Histology showed similarities between the thoracic and lumbar PELs. Fifteen separate PELs were identified within these five thoracic sections. The thoracic PEL has sufficient tensile strength to present a risk to the integrity of the dural sheath during surgery, and surgeons should be aware of these connections when operating on the thoracic spine. PELs may also contribute to the circulation of CSF in the spinal subarachnoid space. PMID- 29569700 TI - A possible association between medial depression of mandibular ramus and maximum bite force. AB - BACKGROUND: Medial depression of the mandibular ramus (MDMR) is an anatomical depression with unknown etiology and described as a result of a slender mandibular ramus in the area of the mandibular notch. It is suggested that MDMR may be due to variations in muscle functions. The aim of this study is to compare the bite force of patients with and without MDMR detected on panoramic radiographs. MATERIAL AND METHODS: A hundred and ten patients (55 women and 55 men; mean age 22.69 +/- 2.85 years) participated in this study. Patients were divided into two groups based on the prevalence of MDMR. Bite force of 55 patients with MRMD and 55 patients without MDMR were determined using a bite force sensor. Non-parametric tests were used to assess differences between groups. RESULTS: Measurements showed statistically significant differences in bite force between genders (p=0.00) with men having higher values (535.98+187.85 N) than women (363.59 + 139.56 N). The mean bite force in the sides with and without MDMR was 538.19 + 196.94 N and 396.22 + 157.69 N, respectively. There was a statistically significant difference between groups with and without MDMR (p=0.00). There was no statistically significant difference in bite force between groups according to Angle classification (p=0.581). CONCLUSIONS: This study suggests that the prevalence of MDMR may be an indicator of high muscle activity. Patients with MDMR should be carefully examined for the risk of relapse prior to any surgical intervention. PMID- 29569701 TI - Immunohistochemical characteristics of porcine intrahepatic nerves under physiological conditions and after Bisphenol A administration. AB - BACKGROUND: The neurochemistry of hepatic nerve fibers was investigated in large animal models after dietary exposure to the endocrine disrupting compound known as bisphenol A. MATERIALS AND METHODS: Antibodies against neuronal peptides were used to study changes in hepatic nerve fibers after exposure to bisphenol A (BPA) at varying concentrations using standard immunofluorescence techniques. The neuropeptides investigated were substance P (SP), galanin (GAL), pituitary adenylate cyclase activating polypeptide (PACAP), calcitonin gene regulated peptide (CGRP) and cocaine & amphetamine regulated transcript (CART). Immunoreactive nerve fibers were counted in multiple sections of the liver and among multiple animals at varying exposure levels. The data was pooled and presented as mean +/- SEM. RESULTS: It was found that all of the nerve fibers investigated showed upregulation of these neural markers after BPA exposure, even at exposure levels currently considered to be safe. These results show very dramatic increases in nerve fibers containing the above-mentioned neuropeptides and the altered neurochemical levels may be causing a range of pathophysiological states if the trend of over-expression is extrapolated to developing humans. CONCLUSIONS: This may have serious implications for children and young adults who are exposed to this very common plastic polymer, if the same trends are occurring in humans. PMID- 29569702 TI - An anatomical study of the origin, structure and insertion of the medial patellofemoral ligament. AB - BACKGROUND: Repair and reconstruction of the medial patellofemoral ligament (MPFL) has been undertaken for the treatment of patellar instability. For successful surgery detailed knowledge of the anatomy of the ligament is required. The aim of this study was to describe the origin, structure and insertion of the MPFL. MATERIALS AND METHODS: We studied cadaveric knees from 30 Chinese adults. We studied the origin, course and insertion of the MPFL. RESULTS: We found that the MPFL was composed of two main strands, superficial and deep. We also found that the insertion of the MPFL into the femur had three common patterns. All three were located between the adductor tubercle and the proximal part of superficial medial collateral ligament. CONCLUSIONS: We have added to the anatomical knowledge of the structure of the MPFL. Our study has implications for guiding bone tunnel positioning during MPFL reconstruction surgery.

AB - Traumatic brain injury (TBI) is in part associated with the disruption of the blood-brain barrier. In this study, we analyzed the histopathological changes in E-cadherin and VEGF expression after traumatic brain injury in rats. The rats were divided into 2 groups as the control and the trauma groups. Sprague-Dawley rats were subjected to traumatic brain injury with a weight-drop device using 300 g-1 m weight-height impact. After 5 days of traumatic brain injury, blood samples were taken under ketamine hydroxide anesthesia and biochemical analyzes were performed. The control and trauma groups were compared in terms of biochemical values. There was no change in glutathione (GSH) levels and blood brain barrier permeability. However, malondialdehyde (MDA) and myeloperoxidase activity (MPO) levels increased in the trauma group. In the histopathological examination, choroid plexus in the lateral ventricule, near the piamater membrane, was removed. In the traumatic group, some of epithelial cells were hyperplasic, some of were with local degeneration with peeled off from apical surface. In addition, we observed that congestion in capillary vessels and mononuclear cell infiltration around the vessels. After traumatic brain injury, the increase in vascular endothelial growth factor (VEGF) levels, vascular permeability, and interaction with VEGF receptors in endothelial cells lead to edema in the vessel wall. On the other hand, E-cadherin expression decreased in the tight-junction structures between epithelial cells and basal membrane, resulting in an increase in cerebrospinal fluid in the intervillous area. PMID- 29569704 TI - Morphology of cranial sutures and radiologic evaluation of the variations of intersutural bones. AB - BACKGROUND: As far as our literature searches showed us, morphological characteristics of cranium such as sutures, sutural bones and fontanelles had been examined from the skulls in the museums and dry specimens until now. As a modern method, 3D virtual remodeling of cranial bones by using MDCT-CTA can display in vivo morphological characteristics. In our study, we aimed to determine the presence and incidence of these morphological characteristics that can be clinically significant in our population, by using radiologic methods. MATERIALS AND METHODS: We examined head and neck regions of 185 patients via MDCT CTA. We evaluated radiologically detectable variations of the metopic sutures, lambda, bregma, asterion and pterion, which can be very easily confused with fractures. Additionally, the differences between the genders and incidence of coexistence of these variations were evaluated. RESULTS: According to our study, the incidence of persistent metopic suture was 8.1% and the incidence of lambda variations was 5.9%. Variations were most commonly encountered on the left asterion, and least commonly on the bregma and left pterion. In the evaluation of the coexistence of the parameters and combinations; the wormian bones located at the right and left asterions were detected. There were no statistically significant differences between genders. CONCLUSIONS: Variations of the sutures and sutural bones can be easily misdiagnosed with the fractures of related bony regions in unconscious patients with multiple traumas. During surgical interventions in these type of patients; surgeons must take this fact into consideration in order to make differential diagnosis of fractures and intersutural bone variations. PMID- 29569705 TI - Histological and immunohistochemical characterization of uterine adenocarcinoma in an Asian elephant (Elephas Maximus). AB - A 56 year old nulliparous female Asian elephant (Elephas maximus) living at the zoological garden of Naples (Italy), with a clinical history of recurrent colic, was found in agonal state and humane euthanasia was elected. At necropsy the uterine body was moderately increased in size and the lumen was reduced due to a poorly demarcated and infiltrative neoplasm. Furthermore, multiple, whitish, firm nodules were present in both lungs. Histological examination of the uterine mass revealed epithelial cells arranged in tubular or solid pattern infiltrating the endometrium and the muscular layer. Immunohistochemical examination showed immunoreactivity of neoplastic cells to estrogen receptors antibody. Pulmonary lesions were histologically and immunohistochemically superimposable to the epithelial uterine neoplasm. A definitive diagnosis of uterine adenocarcinoma with pulmonary metastases was made. PMID- 29569706 TI - Bilateral bifid mandibular canal: a case report using cone beam computed tomography. AB - The mandibular canal (MC) originates in the mandibular foramen and runs bilaterally through the mandibular ramus and body, ending in the mental foramen. One of the most common anatomical variations is bifid MC, the configurations of which have been classified into four categories and sub-categories. The prevalence of these variations depends on the imaging method used. Studies carried out in panoramic X-rays and Cone Beam Computed Tomography (CBCT) show prevalences varying between 1% and 20%. In this case report we present the finding of a bilateral bifid MC by CBCT examination; we describe its location and morphological characteristics. The variation found was a Type 1 bilateral bifid MC, which consists in an accessory canal originating from a single mandibular foramen and extending to the third molar or its immediate surroundings. In this report we discuss the importance of detecting these anatomical variations, as well as their implications in clinical practice. PMID- 29569707 TI - Medical students and midwives - How do they view each other? AB - Medical students from James Cook University who had completed their rotation in obstetrics, and midwives working in Cairns Hospital who had undertaken supervision of medical students in the birth suite, were invited to complete anonymous questionnaires on their views of their respective roles in the birth suite. Several issues were identified including increased medical and midwifery student numbers, and lack of communication between midwives and medical students. Increased cooperation and communication between medical and midwifery education providers is urgently needed to improve both student groups' learning experiences. PMID- 29569708 TI - A quick glance at noteworthy articles in this month's issue. PMID- 29569709 TI - The feasibility of a clinical audit tool to investigate stillbirth in Australia - a single centre experience. AB - BACKGROUND: The stillbirth rate in Australia is 7 per 1000 births (Australia's Mothers and Babies 2014-in brief. Perinatal Statistics Series no. 32. Cat no. PER 87, Canberra, AIHW, 2016). The Perinatal Society of Australia and New Zealand (PSANZ) developed guidelines to standardise the investigations into stillbirth. AIMS: To identify causes of stillbirths and stillbirth care using the National Perinatal Death Clinical Audit Tool (National Perinatal Death Clinical Audit Tool, Australian and New Zealand Stillbirth Alliance [ANZSA]/Perinatal Society of Australia and New Zealand [PSANZ]) and compare it to the PSANZ recommendations. Documentation of examination findings and follow-up after stillbirth were also reviewed. MATERIALS AND METHODS: From the total of 515 registered stillbirths at a Queensland hospital, 170 stillbirths were considered unexplained after chart review between July 2004 and September 2014. The National Perinatal Death Clinical Audit Tool was applied and resulting underlying causes of stillbirths were classified using the PSANZ perinatal mortality classification system. RESULTS: The stillbirth rate for this centre was 11.2 per 1000 births. A cause of fetal death was established in 55.4% (93/168) and 75 cases (44.6%) remained unexplained corresponding to 14.6% of all registered stillbirths (75/515). Over half of the women (52.7%) were nulliparous. High rates of autopsy (47.3%), bereavement support (99.4%) and placental histopathology (98.8%) were noted. The general practitioner was notified in 98.7% of cases at the time of stillbirth; 34.1% of babies were small for gestational age at birth, 18.9% were growth restricted at birth and 21.4% of women were current smokers. CONCLUSION: The National Perinatal Death Clinical Audit Tool facilitates and streamlines stillbirth investigations and thus helps to identify underlying causes of stillbirth. PMID- 29569710 TI - Wood: Biology of a living tissue. PMID- 29569712 TI - Cytochrome P450 3A Induction Predicts P-glycoprotein Induction; Part 2: Prediction of Decreased Substrate Exposure After Rifabutin or Carbamazepine. AB - Rifampin demonstrated dose-dependent relative induction between cytochrome P (CYP)3A and P-glycoprotein (P-gp), organic anion transporting polypeptides (OATPs), or CYP2C9; P-gp, OATP, and CYP2C9 induction was one drug-drug interaction (DDI) category lower than that observed for CYP3A across a wide range of pregnane X receptor (PXR) agonism. The objective of this study was to determine if these relationships could be utilized to predict transporter induction by other CYP3A inducers (rifabutin and carbamazepine) and of another P gp substrate, sofosbuvir. Healthy subjects received sofosbuvir and a six-probe drug cassette before and after 300 mg q.d. rifabutin or 300 mg b.i.d. carbamazepine. Induction of P-gp, CYP2C9, and decreased sofosbuvir exposure were successfully predicted by observed CYP3A induction. Carbamazepine induction of OATP was underpredicted, likely due to reported additional non-PXR agonism. The results demonstrate that the effect of a PXR agonist on CYP3A can be leveraged to inform on induction liability for other primarily PXR-regulated P450s/transporters, allowing for prioritization of targeted DDI assessments during new drug development. PMID- 29569711 TI - Garlic intake and gastric cancer risk: Results from two large prospective US cohort studies. AB - Although many case-control studies suggested that garlic intake may reduce gastric cancer risk, evidence from prospective cohort studies has been lacking. We examined the association between garlic intake and subsequent risk of gastric cancer among 77,086 women in the Nurses' Health Study (1984-2014) and 46,398 men in the Health Professionals Follow-Up Study (1986-2014). Relative risks (RRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards models. We additionally examined garlic intake in relation to Helicobacter pylori (H. pylori) infection among 613 participants using logistic regression. During up to 30 years of follow-up, 292 participants were diagnosed with gastric cancer. The pooled multivariable RR of gastric cancer among participants who ate garlic, as compared to those who did not, were 1.11 (95% CI = 0.81-1.51) for the intake of garlic less than once per week, 0.98 (95% CI = 0.71-1.36) for one to four times per week and 1.39 (95% CI = 0.89-2.17) for five or more times per week (p for trend = 0.23). Similarly, no statistically significant association was observed cross-sectionally between garlic intake and H. pylori infection (comparing five or more times per week to never, pooled multivariable odds ratio = 1.66, 95% CI = 0.89-3.09; p for trend = 0.11). The findings from this large prospective study do not support the hypothesis that high garlic intake reduces risk of gastric cancer. PMID- 29569713 TI - Adiposity and breast cancer risk in postmenopausal women: Results from the UK Biobank prospective cohort. AB - Body size is an important modifiable risk factor for postmenopausal breast cancer. However, it remains unclear whether direct measures of fat mass are better indicators of risk than anthropometric measures, or whether central adiposity may contribute to risk beyond overall adiposity. We analyzed data from 162,691 postmenopausal women in UK Biobank followed from 2006 to 2014. Body size was measured by trained technicians. Multivariable-adjusted Cox regression was used to estimate relative risks. Analyses were stratified by age at recruitment, region and socioeconomic status, and adjusted for family history of breast cancer, age at menarche, age at first birth, parity, age at menopause, previous hormone replacement therapy use, smoking, alcohol intake, height, physical activity and ethnicity. We observed 2,913 incident invasive breast cancers during a mean 5.7 years of follow-up. There was a continuous increase in risk of postmenopausal breast cancer with increasing adiposity, across all measures. The point estimate, comparing women in the top (median 37.6 kg) to bottom (median 17.6 kg) quartile of body fat mass was 1.70 (95% confidence interval 1.52-1.90). The magnitudes of the associations between per SD increase in BMI and body fat mass with breast cancer risk were similar, suggesting impedance measures of fat were not substantially better indicators of risk than anthropometric measures. After adjusting for body fat mass, the associations between anthropometric measures of central adiposity and breast cancer risk were attenuated. The magnitude of risk, across all measures of adiposity, was greater in women who had been postmenopausal for 12 or more years. PMID- 29569714 TI - Unexpected involvement of IL-13 signalling via a STAT6 independent mechanism during murine IgG2a development following viral vaccination. AB - In this study, recombinant pox viral vaccination was shown to induce highly elevated IgG2a and low IgG1 antibody expression in mice lacking IL-4 or STAT6, whilst IL-13-/- mice exhibited elevated IgG1, but very low IgG2a. These findings revealed that IL-13 and IL-4 differentially regulated antibody development. To understand this further, when STAT6-/- mice were given a vaccine co-expressing IL 13Ralpha2 that temporarily sequestered IL-13, significantly reduced IgG2a expression, was detected. These findings for the first time demonstrated that IL 13 regulated IgG2a differentiation utilising an alternative IL-13R signalling pathway independent of STAT6 (IL-13Ralpha2 pathway). This was further corroborated by the (i) elevated IL-13Ralpha2 expression detected on STAT6-/- lung MHCII+ CD11c+ cells 24 h post IL-13 inhibitor vaccination and ii) significant up-regulation of IL-13Ralpha2 expression on spleen and lung derived MHCII+ CD11c+ following inhibition of STAT6 signalling in vitro, or vaccination with IL-4R/STAT6 antagonist in vivo. When T follicular helper (Tfh) cells which regulate antibody differentiation were assessed post vaccination, although no difference in IL-4 expression was observed, greatly reduced IFN-gamma expression was detected in IL-13-/- and STAT6-/- mice compared to wild-type. These findings support the notion that the balance of IL-13 level at the vaccination site can differentially regulate T and B-cell immune outcomes. PMID- 29569715 TI - A randomized, controlled trial of two strategies of offering the home-based HPV self-sampling test to non- participants in the Flemish cervical cancer screening program. AB - We conducted a randomized, controlled trial to evaluate different strategies of offering an HPV-self sampling program, and compared this with two control groups. All total of 35,354 women who did not participate in the Flemish cancer screening program were included in the study: 9,118 received a HPV self-collection brush (RIATOL qPCR HPV genotyping test (qPCR [E6/E7]); 9,098 were offered the opportunity to order an HPV-selfsampling brush, 8,830 received the recall letter; 8,849 received no intervention. Within 12 months after the mailing, 18.7% of the women who had received the brush, participated by returning a self-sample sample, while 10.6% women allocated to the opt- in group did so. 10.5% women who received the standard recall letter, had a PAP smear taken within a period of 12 months; while 8% women did so without receiving an intervention at all. Participation in postmenopausal women was higher than in women younger than 50 in both self sampling arms. Screening by means of the self-sample kit increased by age, contradictory when screening is performed by a PAP smear. Of those testing hrHPV positive (9.5%), 88.9% attended for follow up cytology. The mean DNA concentration, found in the self-sampler, decreased by age, causing a higher number of inconclusive results. Our results support the efficacy of a self sampling strategy to increase participation in the Flemish screening program. Self-sampling seems particularly acceptable to postmenopausal non-responders. Future research should focus on the performance of different self-sampling devices in post-menopausal women as low DNA concentrations exponentially increased over age. PMID- 29569716 TI - Genetic and clonal dissection of osteosarcoma progression and lung metastasis. AB - Osteosarcoma is a primary malignant bone tumor that has a high potential to metastasize to lungs. Little is known about the mechanisms underlying the dissemination of OS cancer cells to lungs. We performed whole exome sequencing of 13 OS primary tumors, with matched lung metastases and normal tissues. Phylogenetic analyses revealed that lung metastatic tumors often harbor clones that are nonexistent or rare in the matched primary OS tumors. Spatially and temporally separated lung metastases were from parallel seeding events with a polyphyletic pattern. Loss of TP53 or RB1 is among the early events during OS tumorigenesis, while loss of PTEN is involved at the later stages associated with lung metastases. Finally, KEAP1 was identified as a novel biomarker for increased metastatic risk. Patients whose primary tumors harbored KEAP1 amplification have significantly poorer lung-metastasis free survival. This finding was validated in two independent datasets. Further, in vitro experiments exhibited that KEAP1 depletion suppressed the invasion of OS cells. Our findings uncover the patterns of clonal evolution during OS progression and highlight KEAP1 as a novel candidate associated with the risk of lung metastasis in OS patients. PMID- 29569718 TI - Human papillomavirus type specific risk of progression and remission during long term follow-up of equivocal and low-grade HPV-positive cervical smears. AB - The prevalence of clinically relevant HPV types and their specific risk for progression and regression in women with atypical squamous cells of uncertain significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL) were studied in a routine screening population. A 4-year cohort of women (n = 820) with ASCUS/LSIL and a positive HPV test in triage were followed for 6-9 years. The progression risks for CIN2+/CIN3+ were determined for single (71.2%) and multiple HPV infections (28.8%). The CIN2+ progression risk for all HPV 16, all HPV 35, single HPV 16 and single HPV 35 infections were 65.3% (95% CI: 59.6 71.0), 64.4% (95% CI: 50.4-78.4), 63.8% (95% CI: 56.2-71.4) and 73.7% (95% CI: 53.9-93.5), respectively. Based on CIN2+ progression risks four main groups were defined; the HPV 16 group, the HPV 31/33/35 group, the HPV 18/45/51/52 group and the HPV 39/56/58/59/66/68 group with progression risks of 65.3% (95% CI: 59.6 71.0), 62.1% (95% CI: 54.8-69.4), 52.6 (95% CI: 45.9-59.3) and 39.5 (95% CI: 33.0 46.0), respectively. In multivariate analyses, women in the age group 40-49 years had an increased risk of CIN2+ progression. As for CIN3+, HPV 16 had a higher progression risk than other HPV risk groups (p < 0.05). In multiple infections only HPV 16 had a significant additive CIN3+ progression risk (p < 0.05) as compared to other HPV risk groups. In summary, HPV types 16 and 35, including the HPV risk group 31/33/35, had a similar CIN2+ progression risk, but only HPV 16 had a higher risk for CIN3+ progression. PMID- 29569717 TI - The effect of FASN inhibition on the growth and metabolism of a cisplatin resistant ovarian carcinoma model. AB - Overexpression of fatty acid synthase (FASN), a key regulator of the de novo synthesis of fatty acids, has been demonstrated in a variety of cancers and is associated with poor prognosis and increased multidrug resistance. Inhibition of FASN with the anti-obesity drug orlistat has been shown to have significant anti tumourigenic effects in many cancers, notably breast and prostate. In our study, we investigated whether FASN inhibition using orlistat is an effective adjunctive treatment for ovarian cancers that have become platinum resistant using a cisplatin-resistant ovarian tumour xenograft model in mice. Mice were treated with orlistat or cisplatin or a combination and metabolite analysis and histopathology were performed on the tumours ex vivo. Orlistat decreased tumour fatty acid metabolism by inhibiting FASN, cisplatin reduced fatty acid beta oxidation, and combination treatment delayed tumour growth and induced apoptotic and necrotic cell death in cisplatin-resistant ovarian cancer cells over and above that with either treatment alone. Combination treatment also decreased glutamine metabolism, nucleotide and glutathione biosynthesis and fatty acid beta oxidation. Our data suggest that orlistat chemosensitised platinum-resistant ovarian cancer to treatment with platinum and resulted in enhanced efficacy. PMID- 29569719 TI - A note on Type S/M errors in hypothesis testing. AB - Motivated by the recent replication and reproducibility crisis, Gelman and Carlin (2014, Perspect. Psychol. Sci., 9, 641) advocated focusing on controlling for Type S/M errors, instead of the classic Type I/II errors, when conducting hypothesis testing. In this paper, we aim to fill several theoretical gaps in the methodology proposed by Gelman and Carlin (2014, Perspect. Psychol. Sci., 9, 641). In particular, we derive the closed-form expression for the expected Type M error, and study the mathematical properties of the probability of Type S error as well as the expected Type M error, such as monotonicity. We demonstrate the advantages of our results through numerical and empirical examples. PMID- 29569720 TI - Drug survival of secukinumab for moderate-to-severe plaque psoriasis.

AB - BACKGROUND AND PURPOSE: Liver ischaemia and reperfusion (IR) injury is a sterile inflammatory response involving production of ROS. Mitochondrial homeostasis is maintained by mitochondrial quality control (QC). Thioredoxin (TRX) 2 is a key mitochondrial redox-sensitive protein. Resolvin D1 (RvD1), a specialized pro resolving lipid mediator, exerts anti-inflammatory and antioxidant activities. We investigated mechanisms of RvD1 protection against IR-induced oxidative damage to the liver, focusing on TRX2-mediated mitochondrial QC. EXPERIMENTAL APPROACH: Mice underwent partial warm IR. RvD1 was administered 1 h before ischaemia and immediately prior to reperfusion. Human liver carcinoma HepG2 cells were exposed to hypoxia/reoxygenation and transfected with TRX2 siRNA. Immunohistochemistry, Western blotting and enzyme assays were used to follow changes in mitochondrial structure and function. KEY RESULTS: RvD1 attenuated hepatocellular damage following IR, assessed by serum aminotransferase activities and histology. RvD1 reduced mitochondrial swelling, lipid peroxidation and glutamate dehydrogenase release. Impaired activities of mitochondrial complexes I and III were restored by RvD1. RvD1 enhanced expression of the mitophagy-related protein, Parkin and inhibited accumulation of PTEN-induced putative kinase 1. RvD1 restored levels of mitochondrial biogenesis proteins including PPARgamma coactivator 1alpha, nuclear respiratory factor 1 and mitochondrial transcription factor A and mtDNA level. RvD1 attenuated the increase in levels of the mitochondrial fission-related protein, dynamin-related protein 1. IR reduced TRX2 levels while increasing TRX2 association with TRX-interacting protein. RvD1 attenuated these changes. The regulatory effects of RvD1 on mitochondrial QC were abolished by TRX2 knockdown. CONCLUSIONS AND IMPLICATIONS: We suggest that RvD1 ameliorated IR-induced hepatocellular damage by regulating TRX2-mediated mitochondrial QC. PMID- 29569723 TI - Cytochrome P450 3A Induction Predicts P-glycoprotein Induction; Part 1: Establishing Induction Relationships Using Ascending Dose Rifampin. AB - Drug transporter and cytochrome P450 expression is regulated by shared nuclear receptors and, hence, an inducer should induce both, although the magnitude may differ. The objective of this study was to establish relative induction relationships between CYP3A and drug transporters (P-glycoprotein (P-gp), organic anion transporting polypeptide (OATP), and breast cancer resistance protein (BCRP)) or other P450s (CYP2C9 and CYP1A2) using ascending doses of the prototypical pregnane xenobiotic receptor (PXR) agonist, rifampin, to elicit weak, moderate, and strong PXR agonism. Healthy subjects received dabigatran etexilate, pravastatin, rosuvastatin, and a midazolam/tolbutamide/caffeine cocktail before and after rifampin 2, 10, 75, or 600 mg q.d. Unlike CYP3A, only moderate induction of P-gp, OATP, and CYP2C9 was observed and dose-dependent induction of P-gp, OATP, and CYP2C9 was always one drug-drug interaction category lower than observed for CYP3A, even when correcting for probe drug sensitivity. Data from this study establish proof-of-concept that P450 induction data can be leveraged to inform on the effect on transporters. PMID- 29569722 TI - Etiology of hepatocellular carcinoma in West Africa, a case-control study. AB - Hepatocellular carcinoma (HCC) is a leading cause of cancer in West Africa where HBV infection is endemic. However, limited information is available on other risk factors such as alcohol use, HCV and HIV infection. A case-control study was conducted in referral hospitals of Abidjan (Cote d'Ivoire), Bamako (Mali) and Lome (Togo). Cases were matched with controls on age, gender and participating site. The diagnosis of HCC relied on the combination of one or more space occupying lesions suggestive of an HCC on a standardized abdominal ultrasound and an alpha-fetoprotein level >=400 ng/ml. HIV, HBV and HCV serology were performed. Hazardous alcohol use was assessed using the AUDIT questionnaire. A conditional logistic regression model was used to measure odds ratio (OR) with their 95% confidence intervals (CI). A total of 160 cases and 320 controls were included. Cases were predominantly men (80.0%) with a median age of 47 years (IQR 38-57). Hazardous alcohol use (OR = 4.5 [CI 1.1-18.5]), HBV infection (OR = 62.5 [CI 20.5 190.7]) and HCV infection OR = 35.9 [CI 10.0-130.3]) were independently associated with HCC. Combining the effect of HBV infection and alcohol, HBV infected hazardous drinkers had an OR = 149.8 (CI 13.5-1 667.0), HBV mono infected had an OR = 57.4 (CI 18.8-175.3) (ref: HBV-negative). Aside the independent association of alcohol use and HBV and HCV infection with HCC, a synergic effect between alcohol use and HBV infection was identified. Timely screening and care of HBV infection and hazardous drinking might prevent a significant number of HCC in West Africa. PMID- 29569724 TI - Multi-regional sequencing reveals intratumor heterogeneity and positive selection of somatic mtDNA mutations in hepatocellular carcinoma and colorectal cancer. AB - Recent studies have revealed significant intratumor heterogeneity (ITH) of nuclear genome mutations and highlighted its function in tumor progression and treatment resistance. However, the ITH of somatic mitochondrial DNA (mtDNA) mutations detected in cancers remains unknown. In this study, we performed multiregional mtDNA sequencing of tumor and paratumor tissue samples from 12 hepatocellular carcinoma (HCC) and 13 colorectal cancer (CRC) patients. A substantial level of mtDNA mutations was found in paired non-HCC inflammatory tissues, suggesting that these tissues might not be mtDNA-genetically "normal." Moreover, our data indicated that the ITH of somatic mtDNA mutations was a common feature in HCC and CRC patients. In addition, we found that shared mutations which were observed in at least 2 samples in each patient exhibited a significantly higher heteroplasmic level than mutations that were private to a specific tumor region from both HCC (p = 0.039) and CRC patients (p = 0.001). The heteroplasmic level of shared mutations was positively correlated with intratumoral recurrence of mtDNA mutations. We also found that shared mutations in tumor tissues with a higher degree of pathogenicity risk exhibited a higher heteroplasmic level and intratumoral recurrence in both HCC and CRC patients. These findings suggest that some mtDNA mutations may undergo positive selection during the clonal expansion. Taken together, our analyses identified various levels of ITH of somatic mtDNA mutations in HCC and CRC patients and provided evidence supporting the positive selection working on some somatic mtDNA mutations in tumor tissues.

PMID- 29569726 TI - Xerostomia, salivary characteristics and gland volumes following intensity modulated radiotherapy for nasopharyngeal carcinoma: a two-year follow up. AB - BACKGROUND: To evaluate changes in xerostomia status, salivary characteristics and gland volumes 2 years following radiotherapy in nasopharyngeal carcinoma patients. METHODS: Xerostomia scores, salivary flow rates, pH and buffering capacity were measured at pre-radiotherapy, mid-radiotherapy, 2 weeks, 3 months and 2 years post-radiotherapy. Salivary gland volumes and their correlation with radiation dose were also assessed. RESULTS: Mean radiation dose to oral cavity, parotid and submandibular glands (SMG) was 44.5, 65.0 and 38.6 Gy respectively. Parotid and SMG volumes decreased 33% at 3 months post-radiotherapy; volumes at 2 years post-radiotherapy were 84% and 51% of pre-radiotherapy levels, respectively. Correlations were observed between parotid gland volume per cent reduction and its radiation dose and between resting salivary flow rate reduction and post-radiotherapy/pre-radiotherapy SMG volume ratio. Salivary flow rates and resting saliva pH remained significantly low at 2 years post-radiotherapy (both flow rates, P = 0.001; resting saliva pH, P = 0.005). Similarly, xerostomia scores remained significantly higher compared with pre-radiotherapy levels. CONCLUSIONS: Submandibular gland volumetric shrinkage persisted 2 years after radiotherapy. Xerostomia scores remained significantly higher, and salivary flow rates and resting saliva pH remained significantly lower, suggesting that study participants were still at risk for hyposalivation-related oral diseases.

PMID- 29569728 TI - Automatic intraoperative stitching of nonoverlapping cone-beam CT acquisitions. AB - PURPOSE: Cone-beam computed tomography (CBCT) is one of the primary imaging modalities in radiation therapy, dentistry, and orthopedic interventions. While CBCT provides crucial intraoperative information, it is bounded by a limited imaging volume, resulting in reduced effectiveness. This paper introduces an approach allowing real-time intraoperative stitching of overlapping and nonoverlapping CBCT volumes to enable 3D measurements on large anatomical structures. METHODS: A CBCT-capable mobile C-arm is augmented with a red-green blue-depth (RGBD) camera. An offline cocalibration of the two imaging modalities results in coregistered video, infrared, and x-ray views of the surgical scene. Then, automatic stitching of multiple small, nonoverlapping CBCT volumes is possible by recovering the relative motion of the C-arm with respect to the patient based on the camera observations. We propose three methods to recover the relative pose: RGB-based tracking of visual markers that are placed near the surgical site, RGBD-based simultaneous localization and mapping (SLAM) of the surgical scene which incorporates both color and depth information for pose estimation, and surface tracking of the patient using only depth data provided by the RGBD sensor. RESULTS: On an animal cadaver, we show stitching errors as low as 0.33, 0.91, and 1.72 mm when the visual marker, RGBD SLAM, and surface data are used for tracking, respectively. CONCLUSIONS: The proposed method overcomes one of the major limitations of CBCT C-arm systems by integrating vision-based tracking and expanding the imaging volume without any intraoperative use of calibration grids or external tracking systems. We believe this solution to be most appropriate for 3D intraoperative verification of several orthopedic procedures. PMID- 29569730 TI - Determination of phenolic compounds in ancient and modern durum wheat genotypes. AB - Due to its significant amount of antioxidants, durum wheat (Triticum turgidum ssp. durum) could potentially contribute to the protection against a number of chronic diseases, such as diabetes, cardiovascular disease, and cancer. The increasing interest toward healthy food among both consumers and scientists has moved the focus toward the phytochemical content of whole wheat grains. The aim of this study was to identify the phytochemical composition of 22 cultivars belonging to old and modern durum wheat genotypes, including antioxidant capacity (DPPH and FRAP tests). In addition, five phenolic acids involved in the vanillin biosynthesis pathway and in the defence mechanism of plants were screened using UHPLC-MS/MS. Remarkable quantitative differences in the amount of the five phenolic acids analysed (p < 0.05) were detected among the wheat genotypes investigated. Results showed that among the investigated phenolic compounds, trans-ferulic acid was the most abundant, ranging from 13.28 to 324.69 MUg/g; all the other identified compounds were present at lower concentrations. Moreover, significant differences on the antioxidant activity were observed. Collected data suggested possible differences between biosynthetic pathway of secondary metabolites among durum wheat genotypes. PMID- 29569729 TI - A single exercise bout and locomotor learning after stroke: physiological, behavioural, and computational outcomes. AB - KEY POINTS: Previous work demonstrated an effect of a single high-intensity exercise bout coupled with motor practice on the retention of a newly acquired skilled arm movement, in both neurologically intact and impaired adults. In the present study, using behavioural and computational analyses we demonstrated that a single exercise bout, regardless of its intensity and timing, did not increase the retention of a novel locomotor task after stroke. Considering both present and previous work, we postulate that the benefits of exercise effect may depend on the type of motor learning (e.g. skill learning, sensorimotor adaptation) and/or task (e.g. arm accuracy-tracking task, walking). ABSTRACT: Acute high intensity exercise coupled with motor practice improves the retention of motor learning in neurologically intact adults. However, whether exercise could improve the retention of locomotor learning after stroke is still unknown. Here, we investigated the effect of exercise intensity and timing on the retention of a novel locomotor learning task (i.e. split-belt treadmill walking) after stroke. Thirty-seven people post stroke participated in two sessions, 24 h apart, and were allocated to active control (CON), treadmill walking (TMW), or total body exercise on a cycle ergometer (TBE). In session 1, all groups exercised for a short bout (~5 min) at low (CON) or high (TMW and TBE) intensity and before (CON and TMW) or after (TBE) the locomotor learning task. In both sessions, the locomotor learning task was to walk on a split-belt treadmill in a 2:1 speed ratio (100% and 50% fast-comfortable walking speed) for 15 min. To test the effect of exercise on 24 h retention, we applied behavioural and computational analyses. Behavioural data showed that neither high-intensity group showed greater 24 h retention compared to CON, and computational data showed that 24 h retention was attributable to a slow learning process for sensorimotor adaptation. Our findings demonstrated that acute exercise coupled with a locomotor adaptation task, regardless of its intensity and timing, does not improve retention of the novel locomotor task after stroke. We postulate that exercise effects on motor learning may be context specific (e.g. type of motor learning and/or task) and interact with the presence of genetic variant (BDNF Val66Met). PMID- 29569731 TI - Exercise and prostate cancer: From basic science to clinical applications. AB - Prostate cancer (PCa) is a disease of increasing medical significance worldwide. In developed countries, PCa is the most common non-skin cancer in men, and one of the leading causes of cancer-related deaths. Exercise is one of the environmental factors that have been shown to influence cancer risk. Moreover, systemic reviews and meta-analysis have suggested that total physical activity is related to a decrease in the risk of developing PCa. In addition, epidemiological studies have shown that exercise, after diagnosis, has benefits regarding PCa development, and positive outcome in patients under treatment. The standard treatment for locally advanced or metastatic PCa is Androgen deprivation therapy (ADT). ADT produces diverse side effects, including loss of libido, changes in body composition (increase abdominal fat), and reduced muscle mass, and muscle tone. Analysis of numerous research publications showed that aerobic and/or resistance training improve patient's physical condition, such us, cardiorespiratory fitness, muscle strength, physical function, body composition, and fatigue. Therefore, exercise might counteract several ADT treatment-induced side effects. In addition of the aforementioned benefits, epidemiological, and in vitro studies have shown that exercise might decrease PCa development. Thus, physical activity might attenuate the risk of PCa and supervised exercise intervention might improve deleterious effects of cancer treatment, such as ADT side effects. This review article provides evidence indicating that exercise could complement, and potentiate, the current standard treatments for advanced PCa, probably by creating an unfavorable microenvironment that can negatively affect tumor development, and progression. PMID- 29569732 TI - Unusual twinning: Additional findings during prenatal diagnosis of twin zygosity by single nucleotide polymorphism (SNP) array. AB - OBJECTIVE: To evaluate the incidence and characteristics of unusual twinning by using single nucleotide polymorphism (SNP) array to identify twin zygosity. METHODS: This study reviewed 386 twin pairs who were seen for prenatal or postnatal diagnosis and underwent SNP array to detect zygosity. RESULTS: The incidence of monozygotic (MZ) twins was 11.36% (25/220) in the assisted reproductive technology (ART)-conceived group. Monochorionic dizygotic twins represented 3 of 24 monochorionic ART-conceived twin pairs (3/24, 12.50%) but none in the spontaneous twin pairs. Among 4 single-embryo transfer twin pairs, 3 represented unusual twinning, including 2 MZ twin pairs with discordant karyotypes and 1 dizygotic twin pair of the same gender. Of the pregnancies with 2 or more embryos transferred, 7.77% (15/193) were MZ. Additionally, there was a dichorionic monozygotic twin pair with placental vascular anastomoses from a day 5 blastocyst transfer. CONCLUSION: Single nucleotide polymorphism array can provide zygosity diagnosis in addition to chromosomal copy number variation and uniparental disomy detection. ART twin pregnancies have a risk of unusual twinning, such as monochorionic dizygotic, single-embryo transfer twin pairs with discordant karyotypes or dizygotic, and dichorionic monozygotic with vascular anastomoses from day-5 transfer.

PMID- 29569734 TI - Remarkable genetic diversity detected at river buffalo prolactin receptor (PRLR) gene and association studies with milk fatty acid composition. AB - Prolactin is an anterior pituitary peptide hormone involved in many different endocrine activities and is essential for reproductive performance. This action is mediated by its receptor, the prolactin receptor, encoded by the PRLR gene. In this study, we sequenced and characterized the Mediterranean river buffalo PRLR gene (from exon 3 to 10), and we found remarkable genetic diversity. In particular, we found 24 intronic polymorphisms and 13 exonic SNPs, seven of which were non-synonymous. Furthermore, the polymorphisms identified in the 3'-UTR were investigated to establish their possible influence on microRNA binding sites. Considering all the amino acid changes and the observed allelic combinations, it is possible to deduce at least six different translations of the buffalo prolactin receptor and, consequently, the presence at the PRLR gene of at least six alleles. Furthermore, we identified a deletion of a CACTACC heptamer between nucleotides 1102 and 1103 of exon 10 (3'-UTR), and we developed an allele specific PCR to identify the carriers of this genetic marker. Finally, the SNP g.11188A>G, detected in exon 10 and responsible for the amino acid replacement p.His328Arg, was genotyped in 308 Italian Mediterranean river buffaloes, and an association study with milk fat traits was carried out. The statistical analysis showed a tendency that approached significance for the AA genotype with higher contents of odd branched-chain fatty acids. Thus, our results suggest that the PRLR gene is a good candidate for gene association studies with qualitative traits related to buffalo milk production. PMID- 29569735 TI - Anisakis pegreffii impacts differentiation and function of human dendritic cells. AB - Human dendritic cells (DCs) show remarkable phenotypic changes when matured in the presence of helminth-derived products. These modifications frequently elicited a polarization towards Th2 cells and regulatory T cells thus contributing to immunological tolerance against these pathogens. In this study, the interaction between DCs and larvae of the zoonotic anisakid nematode Anisakis pegreffii was investigated. A. pegreffii larvae were collected from fish hosts, and monocyte-derived DCs were cocultured in the presence of the live larvae (L) or its crude extracts (CE). In both experimental conditions, A. pegreffii impacted DC viability, hampered DC maturation by reducing the expression of molecules involved in antigen presentation and migration (ie HLA-DR, CD86, CD83 and CCR7), increased the phagosomal radical oxygen species (ROS) levels and modulated the phosphorylation of ERK1,2 pathway. These biological changes were accompanied by the impairment of DCs to activate a T-cell-mediated IFNgamma. Interestingly, live larvae appeared to differently modulate DC secretion of cytokines and chemokines as compared to CE. These results demonstrate, for the first time, the immunomodulatory role of A. pegreffii on DCs biology and functions. In addition, they suggest a dynamic contribution of DCs to the induction and maintenance of the inflammatory response against A. pegreffii. PMID- 29569736 TI - Safety and efficacy of ledipasvir/sofosbuvir with or without ribavirin in hepatitis C genotype 1 patients including those with decompensated cirrhosis who failed prior treatment with simeprevir/sofosbuvir. AB - BACKGROUND: Combination therapy of simeprevir (SIM)/sofosbuvir (SOF) is an approved treatment for hepatitis C genotype (gen) 1 with overall SVR12 rate of 85%-95%. The single tablet fixed-dose combination of ledipasvir (LDV)/SOF is also approved for gen 1 with sustained virologic response at 12 weeks (SVR12) rates >=95%. No data are available on the efficacy of retreatment with LDV/SOF in patients who failed initial treatment with SIM/SOF. AIM: To evaluate the efficacy of retreatment with LDV/SOF +/- ribavirin (RBV) in gen 1 patients who had previously failed treatment with SIM/SOF. METHODS: Data from a combined treatment cohort of 2 hepatology centres, which included patients previously treated with SIM/SOF +/- RBV for 12 weeks but failed to achieve SVR and then underwent retreatment with LDV/SOF +/- RBV, were analysed (n = 30). LDV/SOF +/- RBV was administered for 12-24 weeks based on the discretion of the treating hepatologist. RESULTS: Of the 30 patients, 23 (77%) were male, 77% were Caucasian and 26 (87%) were gen 1a. 26 (86%) had cirrhosis, of which 16 (62%) had decompensated, Child's class B or C cirrhosis. Three patients were liver transplant recipients with recurrent hepatitis C. Overall, 27/30 (90%) achieved SVR. Treatment was well tolerated with 37% reporting no adverse events. The most common adverse events were fatigue, headache, insomnia and nausea. Two patients with Child's B cirrhosis required hospitalization during treatment for variceal haemorrhage and abdominal pain respectively. However, no treatment discontinuations or deaths occurred. CONCLUSION: Single tablet fixed-dose combination LDV/SOF +/- RBV is efficacious and well tolerated in patients who previously failed treatment with SIM/SOF, including those with decompensated cirrhosis and recurrent hepatitis C following liver transplantation. PMID- 29569737 TI - Comparison of oral health status and daily nutrient intake between elders who live alone and elders who live with family: Based on the Korean National Health and Nutrition Examination Survey (KNHANES VI) (2013-2015). AB - OBJECTIVE: To compare the nutritional factors and oral status of elders living alone and elders living with their families in Korea. BACKGROUND: Numerous studies have found that the presence of fewer remaining teeth is associated with decreased nutrient intake; however, there is no study comparing the nutritional status and oral status of elders living alone with that of elders living with family based on a nationally representative sample. METHODS: A sample of 2904 individuals who participated in the sixth Korean National Health and Nutrition Examination Survey was reviewed (65-84 years of age). Living status was defined according to the participants' self-reported questionnaire, and a nutrient intake questionnaire was designed as an open questionnaire and used during the face-to face interviews. The number of existing teeth was used to determine oral status. A complex-sample general linear analysis and multivariate logistic regression analysis were used to evaluate the association between the number of teeth and nutrient intake among elders living with family and elders living alone after adjusting for confounders. RESULTS: Elders living alone were significantly older and tended to have the following characteristics: women, lower household income, lower educational level, poor perceived health status, non-smokers, non-drinkers and lack of physical activity. Elders living alone had a poorer perceived oral health status, had not received an oral examination in the past year, had chewing problems and had fewer existing teeth (P < .05). Elders living with family showed better oral health and nutrient intake status. Participants who had many existing teeth had higher nutrient intake than the participants who had fewer existing teeth. CONCLUSIONS: For healthy lives at old age, family support or additional social support for elders living alone should be considered. PMID- 29569738 TI - Tandem HILIC-RP liquid chromatography for increased polarity coverage in food analysis. AB - Comprehensive non-targeted analysis of food products normally requires two complementary chromatographic runs to achieve maximum compound coverage. In this study, we present a sensitive tandem-LC method, which combines RP and HILIC separation in a single run. The setup consists of a C18 trap column and two subsequently coupled analytical columns (HILIC and C18) which are operated in parallel. First, hydrophobic compounds are retained on the RP trap column while rather hydrophilic compounds are directly transferred onto a HILIC phase. Next, the pre-fractionated sample composition is analyzed by HILIC or RP chromatography, respectively. The presented setup allows individual and independent gradient elution as well as interfacing with mass spectrometry. The performance of the method has been proven by means of food relevant standards and analysis of complex food samples (e.g. red wine, meat extract). The simple and robust setup provides high flexibility in the selection of column combinations and does not require sophisticated instrumental setups or software. The method significantly increases the covered polarity range compared to classical one dimensional chromatography. Our results indicate that tandem LC is a valuable and universal tool in the non-targeted screening of various types of complex food samples. PMID- 29569739 TI - Chemical exchange-sensitive spin-lock (CESL) MRI of glucose and analogs in brain tumors. AB - PURPOSE: Glucose uptake and metabolism can be measured by chemical exchange sensitive spin-lock (CESL) MRI with an administration of glucose or its analogs. This study investigates the sensitivity, the spatiotemporal characteristics, and the signal source of glucoCESL with a 9L rat brain tumor model. METHODS: Dynamic CESL MRI with intravenous injection of D-glucose, 2-deoxy-D-glucose (2DG), and L glucose were measured and compared with gadolinium-based dynamic contrast enhanced (DCE) MRI. RESULTS: The CESL signals with an injection of glucose or analogs have faster and larger changes in tumors than normal brain tissue. In tumors, the CESL signal with 2DG injection has larger and slower peak response than that with D-glucose due to the accumulation of 2DG and 2DG-6-phosphate in the intracellular compartment, whereas L-glucose, which cannot be transported intracellularly by glucose transporters, only induces a small change. The initial glucoCESL maps (< 4 minutes) are qualitatively similar to DCE maps, whereas later maps (> 4 minutes) show more widespread responses. The rise times of D-glucose CESL and 2DG-CESL signals in the tumor are slower than that of DCE. Our data suggest that the initial CESL contrast primarily reflects a passive increase of glucose content in the extracellular space of tumors due to a higher vascular permeability, whereas the later period may have a significant contribution from the uptake/metabolism of glucose in the intracellular compartment. CONCLUSIONS: Our results demonstrate that glucoCESL MRI has both extracellular and intracellular contributions, and can be a useful tool for measurements of both vascular permeability and glucose uptake in tumors. PMID- 29569740 TI - The Medication Risk of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis in Asians: The Major Drug Causality and Comparison With the US FDA Label. AB - Specific ethnic genetic backgrounds are associated with the risk of Stevens Johnson syndrome / toxic epidermal necrolysis (SJS/TEN) especially in Asians. However, there have been no large cohort, multiple-country epidemiological studies of medication risk related to SJS/TEN in Asian populations. Thus, we analyzed the registration databases from multiple Asian countries who were treated during 1998-2017. A total 1,028 SJS/TEN cases were identified with the algorithm of drug causality for epidermal necrolysis. Furthermore, those medications labeled by the US Food and Drug Administration (FDA) as carrying a risk of SJS/TEN were also compared with the common causes of SJS/TEN in Asian countries. Oxcarbazepine, sulfasalazine, COX-II inhibitors, and strontium ranelate were identified as new potential causes. In addition to sulfa drugs and beta-lactam antibiotics, quinolones were also a common cause. Only one acetaminophen-induced SJS was identified, while several medications (e.g., oseltamivir, terbinafine, isotretinoin, and sorafenib) labeled as carrying a risk of SJS/TEN by the FDA were not found to have caused any of the cases in the Asian countries investigated in this study. PMID- 29569741 TI - The effects of navigator distortion and noise level on interleaved EPI DWI reconstruction: a comparison between image- and k-space-based method. AB - PURPOSE: To study the effects of 2D navigator distortion and noise level on interleaved EPI (iEPI) DWI reconstruction, using either the image- or k-space based method. METHODS: The 2D navigator acquisition was adjusted by reducing its echo spacing in the readout direction and undersampling in the phase encoding direction. A POCS-based reconstruction using image-space sampling function (IRIS) algorithm (POCSIRIS) was developed to reduce the impact of navigator distortion. POCSIRIS was then compared with the original IRIS algorithm and a SPIRiT-based k space algorithm, under different navigator distortion and noise levels. RESULTS: Reducing the navigator distortion can improve the reconstruction of iEPI DWI. The proposed POCSIRIS and SPIRiT-based algorithms are more tolerable to different navigator distortion levels, compared to the original IRIS algorithm. SPIRiT may be hindered by low SNR of the navigator. CONCLUSION: Multi-shot iEPI DWI reconstruction can be improved by reducing the 2D navigator distortion. Different reconstruction methods show variable sensitivity to navigator distortion or noise levels. Furthermore, the findings can be valuable in applications such as simultaneous multi-slice accelerated iEPI DWI and multi-slab diffusion imaging.

AB - A psychrotrophic yeast strain producing a cold-adapted protease at low temperature was classified as Sporobolomyces roseus. In standard YPG medium, S. roseus LOCK 1119 synthesized an extracellular protease with an activity of approximately 560 U/L. Optimization of medium composition and process temperature considerably enhanced enzyme biosynthesis; an approximate 70% increase in activity (2060 U/L). The native enzyme was purified to homogeneity by cation exchange chromatography followed by a size exclusion step, resulting in a 103 fold increase in specific activity (660 U/mg) with 25% recovery. The enzyme displayed 10%-30% of its maximum activity at 0-25 degrees C, with the optimum temperature being 50 degrees C. Protease G8 was strongly inactivated by pepstatin A, an aspartic protease inhibitor. The enzyme was used to hydrolyze four natural substrates, and their antioxidant activities were evaluated against 1,1-diphenyl 2-picrylhydrazyl. The highest antioxidant activity (69%) was recorded for beef casein. PMID- 29569744 TI - Reducing readmission risk following CABG surgery-Doing whatever it takes.

AB - OBJECTIVES: We previously showed that immunization with ex vivo- generated autologous dendritic cells loaded with apoptotic tumor cells (Apo-DC) potentiated tumor-specific immunity in chronic lymphocytic leukemia (CLL) patients. Here, we evaluated safety and immunogenicity of Apo-DC in combination with lenalidomide, granulocyte-macrophage colony-stimulating factor (GM-CSF), and low-dose cyclophosphamide (CTX). METHODS: Ten previously untreated patients with slowly progressing CLL received 5 Apo-DC vaccinations and lenalidomide orally for 24 weeks either alone (cohort I, n = 5) or together with subcutaneous GM-CSF and intravenous CTX (cohort II, n = 5). Tumor-specific T-cell responses were measured by proliferation and IFN-gamma ELISPOT assays. Immune monitoring was performed by flow cytometry. RESULTS: Dose-limiting toxicity was observed in 3/10 patients, 2 in cohort I and one in cohort II. One patient developed autoimmune hemolytic anemia and another grade 4 thrombocytopenia. Vaccine-induced immune responses were seen in 5/5 and 4/5 patients in cohort I and II, respectively. The expression of immune checkpoints on T cells did not change significantly. CONCLUSIONS: Lenalidomide alone or in combination with GM-CSF and low-dose CTX as immune adjuvant to the Apo-DC vaccine elicited tumor-specific T-cell responses in CLL patients. However, unexpected toxicity was observed and caution is suggested in further exploring this drug as immune adjuvant in CLL. PMID- 29569745 TI - Intimal sarcoma of the left atrium. PMID- 29569746 TI - Enantioselective resolution of Rac-terbutaline and evaluation of optically pure R terbutaline hydrochloride as an efficient anti-asthmatic drug. AB - Terbutaline is a beta2 -adrenoceptor agonist for the treatment of asthma and chronic obstructive pulmonary disease (COPD). Among the two isomers of terbutaline (TBT 2), R-isomer was found to be the potent enantiomer in generating therapeutic effect, while S-isomer has been reported to show side effects. In this study, R-terbutaline hydrochloride (R-TBH 6) was synthesized through chiral resolution from the racemic terbutaline sulfate (rac-TBS 1) with 99.9% enantiomeric excess (ee) in good overall yield (53.6%). Further, R-TBH 6 nebulized solution was prepared in half dosage of Bricanyl(r), which is a marketed product of racemic terbutaline and evaluated in vitro aerosol performance and in vivo anti-asthmatic effect on guinea pigs via. pulmonary delivery. From the investigation, it is evident that R-TBH 6 nebulized solution of half dosage performed similar fine aerosol characteristics and anti-asthmatic effect with Bricanyl(r).

PMID- 29569748 TI - Maternal obesity alters uterine NK activity through a functional KIR2DL1/S1 imbalance. AB - In pregnancy, uterine natural killer cells (uNK) play essential roles in coordinating uterine angiogenesis, blood vessel remodeling and promoting maternal tolerance to fetal tissue. Deviances from a normal uterine microenvironment are thought to modify uNK function(s) by limiting their ability to establish a healthy pregnancy. While maternal obesity has become a major health concern due to associations with adverse effects on fetal and maternal health, our understanding into how obesity contributes to poor pregnancy disorders is unknown. Given the importance of uNK in pregnancy, this study examines the impact of obesity on uNK function in women in early pregnancy. We identify that uNK from obese women show a greater propensity for cellular activation, but this difference does not translate into increased effector killing potential. Instead, uNK from obese women express an altered repertoire of natural killer receptors, including an imbalance in inhibitory KIR2DL1 and activating KIR2DS1 receptors that favors HLA-C2-directed uNK activation. Notably, we show that obesity-related KIR2DS1 skewing potentiates TNFalpha production upon receptor crosslinking. Together, these findings suggest that maternal obesity modifies uNK activity by altering the response toward HLA-C2 antigen and KIR2DL1/2DS1-controlled TNFalpha release. Furthermore, this work identifies alterations in uNK function resulting from maternal obesity that may impact early developmental processes important in pregnancy health.

AB - BACKGROUND: Reducing preventable hospital readmissions after coronary artery bypass graft (CABG) surgery has become a national priority. Predictive models can be used to identify patients at high risk for readmission. However, the majority of the existing models are based on data available at discharge. We sought to develop a model to predict hospital readmission using data available soon after admission for isolated CABG surgery. METHODS: Fifty risk factors were included in a bivariate analysis, 16 of which were significantly associated (P < 0.05) with readmissions and were entered into a multivariate logistic regression and removed stepwise, using backward elimination procedures. The derived model was then validated on 896 prospective isolated CABG cases. RESULTS: Of 2589 isolated CABG patients identified between December 1, 2010, and June 30, 2014, 237(9.15%) were readmitted within 30 days. Five risk factors were predictive of 30-day all-cause readmission: age (odds ratio [OR] = 1.03; 95% confidence interval [CI]: 1.01 1.05; P = 0.004), prior heart failure (OR = 1.55; 95%CI: 1.07-2.24; P = 0.020), total albumin prior to surgery (OR = 0.68; 95%CI: 0.05-0.94; P = 0.021), previous myocardial infarction (OR = 1.44; 95%CI: 1.00-2.08; P = 0.50), and history of diabetes (OR = 1.54; 95%CI: 1.09-2.19; P = 0.015). The area under the curve c statistic was 0.63 in the derivation sample and 0.65 in the validation sample showing good discrimination. CONCLUSIONS: A 30-day all-cause readmission among isolated CABG patients can be predicted soon after admission with a small number of risk factors. PMID- 29569751 TI - Diagnostic accuracy of dual-source computed tomography angiography for the detection of coronary in-stent restenosis: A systematic review and meta-analysis. AB - We sought to perform a meta-analysis to comprehensively evaluate the diagnostic accuracy of dual-source computed tomography angiography (DSCTA) in detecting coronary in-stent restenosis (CISR) when compared to invasive coronary angiography. The stent-based research studies in which DSCTA was used as diagnostic tool for CISR, as recent as of October 2017, from several reputed scientific libraries (PubMed, Embase, Scopus, The Cochrane Library, and Web of Science) were evaluated. Study inclusion, data extraction, and risk bias assessment were conducted by two researchers independently. Pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under summary receiver operator characteristics (SROC) curve (AUC) were calculated to assess the diagnostic value. In addition, heterogeneity and subgroup analysis were also carried out. A total of 13 studies with a total of 894 patients and 1384 assessable stents were included. The pooled results of DSCTA diagnosing CISR were as follows: SEN 0.92 (95% confidence interval [CI] 0.87-0.96), SPE 0.91 (95% CI 0.87-0.94), PLR 9.83 (95% CI 6.93-13.94), NLR 0.09 (95% CI 0.05-0.15), DOR 114.73 (95% CI 64.12-205.28), and AUC 0.97 (95% CI 0.95-0.98), respectively. The subgroup analysis result suggested that DSTCA performed significantly better in CISR detection when the stent diameter was >=3 mm compared with the stent diameter <3 mm: (0.98 [0.97-0.99] vs 0.82 [0.79-0.86]) with P < .05. This study revealed that DSCTA has excellent diagnostic performance for detecting CISR and may serve as an alternative for further patient evaluation with CISR, especially for stent diameter >=3 mm. PMID- 29569752 TI - Development of mucosal-associated invariant T cells. AB - Mucosal-associated invariant T (MAIT) cells develop in the thymus and migrate into the periphery to become the largest antigen-specific alphabeta T-cell population in the human immune system. However, the frequency of MAIT cells varies widely between human individuals, and the basis for this is unclear. While MAIT cells are highly conserved through evolution and are phenotypically similar between humans and mice, they represent a much smaller proportion of total T cells in mice. In this review, we discuss how MAIT cells transition through a three-stage development pathway in both mouse and human thymus, and continue to mature and expand after they leave the thymus. Moreover, we will explore and speculate on how specific factors regulate different stages of this process. PMID- 29569753 TI - Comprehensive mapping of cystic fibrosis mutations to CFTR protein identifies mutation clusters and molecular docking predicts corrector binding site. AB - Cystic Fibrosis (CF) is caused by mutations in the CFTR gene, of which over 2000 have been reported to date. Mutations have yet to be analyzed in aggregate to assess their distribution across the tertiary structure of the CFTR protein, an approach that could provide valuable insights into the structure-function relationship of CFTR. In addition, the binding site of Class I correctors (VX 809, VX-661, and C18) is not well understood. In this study, exonic CFTR mutations and mutant allele frequencies described in 3 curated databases (ABCMdb, CFTR1, and CFTR2, comprising >130 000 data points) were mapped to 2 different structural models: a homology model of full-length CFTR protein in the open channel state, and a cryo-electron microscopy core-structure of CFTR in the closed-channel state. Accordingly, residue positions of 6 high-frequency mutant CFTR alleles were found to spatially co-localize in CFTR protein, and a significant cluster was identified at the NBD1:ICL4 interdomain interface. In addition, immunoblotting confirmed the approximate binding site of Class I correctors, demonstrating that these small molecules act via a similar mechanism in vitro, and in silico molecular docking generated binding poses for their complex with the cryo-electron microscopy structure to suggest the putative corrector binding site is a multi-domain pocket near residues F374-L375. These results confirm the significance of interdomain interfaces as susceptible to disruptive mutation, and identify a putative corrector binding site. The structural pharmacogenomics approach of mapping mutation databases to protein models shows promise for facilitating drug discovery and personalized medicine for monogenetic diseases. PMID- 29569754 TI - Evaluation of a bone substitute covered with a collagen membrane for ridge preservation after tooth extraction. Clinical and tomographic randomized controlled study in humans. AB - OBJECTIVE: To evaluate the use of a synthetic bone substitute covered with a collagen membrane for ridge preservation after tooth extraction, by clinical and tomographic analysis. MATERIAL AND METHODS: Fifteen patients, presenting at least two maxillary anterior teeth indicated for extraction, were selected: in the test group (TG), post-extraction sockets were filled by a synthetic bone substitute; in the control group (CG), by blood clot. In both groups, the sockets were covered by a collagen membrane. Cone-beam computerized tomography (CBCT) scans were acquired immediately after and 6 months post-surgically, and horizontal and vertical dimensional bone changes were quantified. RESULTS: Transurgical clinical analysis presented no statistically significant differences between TG and CG (p > .05). CBCT intragroup evaluation presented statistically significant reduction for the buccal alveolar measurement (TG = 1.58 mm or 21.82%, and CG = 1.66 mm or 24.08%) and horizontal cervical measurement (TG = 0.55 mm or 8.30% and CG = 1.30 mm or 17.68%), and not significant for palatal alveolar measurement (TG = 0.44 mm or 3.42% and CG = 0.26 mm or 3.89%). For alveolar height and horizontal apical measurements, this decrease was significant only for the CG, with reductions of 1.03 mm and 0.50 mm, respectively, compared to a decrease of 0.57 mm and 0.19 mm for the TG. The intergroup analysis showed significant difference for cervical horizontal measurement after 6 months (p < .05). CONCLUSION: The results showed that the use of the bone substitute covered with a collagen membrane resulted in less changes in vertical and horizontal alveolar ridge dimensions than the collagen membrane alone.

AB - Gallbladder cancer (GBC) is the most general biliary tract malignancy, with poor prognosis due to rapid tumor progression and lack of specific symptoms. Lactate dehydrogenase-A (LDHA) can promote Warburg effect to produce lactate and Adenosine Triphosphate (ATP) in aerobic condition, which contributes to oncogenesis metastasis and drug resistance in various cancers. However, the expression and functional role of LDHA in GBC are largely unknown. We determined that LDHA was over-expressed in GBC tumor tissues compared with normal tissues, which was also an independent prognostic factor for the overall survival of GBC patients by tissue microarrays analysis. In addition, RNAi-mediated LDHA silencing could suppress the GBC cell proliferation, invasion, colony formation and glycolysis while promoting cell apoptosis in vitro. Similar results were observed in GBC cells treated with LDHA specific inhibitor FX11. Moreover, we confirmed that knockdown of LDHA could inhibit tumor growth in vivo. Additionally, we found that the 3'-untranslated region (3'-UTR) of LDHA mRNA was the direct target of microRNA-30d-5p (miR-30d-5p), which was low expressed in GBC tissues and associated with poor prognosis of GBC patients. Our findings disclose a novel role for miR-30d-5p/LDHA axis contribute to aggressive progression by reprogramming the metabolic process in GBC cells, and suggest a potential application of miR-30d-5p/LDHA axis in prognosis prediction and GBC treatment. PMID- 29569756 TI - Kinetic models for the effect of temperature on flavonoid production in liquid submerged fermentation by Phellinus baumii. AB - Kinetic models and temperature control strategy were established to reflect the effect of temperature (22 degrees C-30 degrees C) on flavonoid production of Phellinus baumii (P. baumii) in 6-L fermentor. A modified Logistic equation, Hinshelwood model, and Luedeking Piret equation were used to describe mycelial growth and product formation. The influence of temperature on the estimated kinetic parameters was further studied by regression analysis. Based on kinetic parameters analysis, the new temperature control strategy was proposed. Briefly, at 0-43 H, decreasing temperature (30 degrees C-28 degrees C) can shorten the lag phase of mycelial growth, and at 43-90 H, fermentation temperature was reduced gradually from 28 degrees C to 24 degrees C to keep high flavonoid productivity. At the fermentation anaphase (90-161 H), temperature was controlled at 24 degrees C to relieve inhibition of flavonoid and maintain constant production capacity of flavonoid. As a result, the maximum flavonoid yield was reached 4.21 mg/100 mg cell dry weight by temperature control strategy, which was 70.45% higher than that at a constant temperature of 26 degrees C. Additionally, the establishment of kinetic models based on fermentation temperature, which presented here may provide a scientific basis for further large scales flavonoid production of P. baumii in submerged fermentation. PMID- 29569757 TI - Quinine-modified polymer monolithic column with reversed-phase /strong anion exchange mixed-mode for pressurized capillary electrochromatography. AB - Via the facile ring-opening reaction of epoxy groups with quinine, a novel polymer monolith with quaternary ammonium for reversed-phase/strong anion exchange mixed-mode has been fabricated for pressurized capillary electrochromatography (pCEC). Optimization on the preparation of quinine-modified monoliths has been investigated, and characteristics including morphology, permeability, mechanical stability, reproducibility, and column performance have been also studied. Active quaternary ammonium groups were conveniently produced to generate cationic action sites and stable anodic electroosmotic flow. Multiple interactions including reversed-phase, strong anion-exchange, electrostatic repulsion and pi-pi stacking interactions were obtained. Satisfactory separation capability of various analytes such as alkylbenzenes, polycyclic aromatic hydrocarbons, benzoic acid and its homologs, and beta2 -receptor excitants has been achieved. Applied to the real sample, the good resolution of three alkaloids in Corydalis yanhusuo were achieved by pCEC with the quinine-modified monolith. The results light a potential access to facilely fabricating quaternary ammonium functionalized polymer monolith with multiple interactions for efficient electrochromatography profiling of various compounds.

AB - Xeroderma pigmentosum (XP) is a rare autosomal recessive skin disorder characterized by hyperpigmentation, premature skin aging, ocular and cutaneous photosensitivity, and increased risk of skin carcinoma. We investigated seven consanguineous XP families with nine patients from Pakistan. All the Patients exhibited typical clinical symptoms of XP since first year of life. Whole genome SNP genotyping identified a 14 Mb autozygous region segregating with the disease phenotype on chromosome 3p25.1. DNA sequencing of XPC gene revealed a founder homozygous splice site mutation (c.2251-1G>C) in patients from six families (A-F) and a homozygous nonsense mutation (c.1399C>T; p.Gln467*) in patients of family G. This is the first report of XPC mutations, underlying XP phenotype, in Pakistani population.

AB - ISSUE ADDRESSED: Physical inactivity is a key health risk among Aboriginal and Torres Strait Islander (Indigenous) Australians. We examined perceptions of the Indigenous Marathon Program (IMP) in a remote Torres Strait island community. METHODS: Semi-structured interviews with community and program stakeholders (n = 18; 14 Indigenous) examined barriers and enablers to running and the influence of the IMP on the community. A questionnaire asked 104 running event participants (n = 42 Indigenous) about their physical activity behaviours, running motivation and perceptions of program impact. Qualitative data were analysed using thematic content analysis, and quantitative data were analysed using descriptive statistics. RESULTS: Interviews revealed six main themes: community readiness, changing social norms to adopt healthy lifestyles, importance of social support, program appeal to hard-to-reach population groups, program sustainability and initiation of broader healthy lifestyle ripple effects beyond running. Barriers to running in the community were personal (cultural attitudes; shyness) and environmental (infrastructure; weather; dogs). Enablers reflected potential strategies to overcome described barriers. Indigenous questionnaire respondents were more likely to report being inspired to run by IMP runners than non Indigenous respondents. CONCLUSIONS: Positive "ripple" effects of the IMP on running and broader health were described to have occurred through local role modelling of healthy lifestyles by IMP runners that reduced levels of "shame" and embarrassment, a common barrier to physical activity among Indigenous Australians. A high initial level of community readiness for behaviour change was also reported. SO WHAT?: Strategies to overcome this "shame" factor and community readiness measurement should be incorporated into the design of future Indigenous physical activity programs. PMID- 29569762 TI - NDRG1 and FOXO1 regulate endothelial cell proliferation in infantile haemangioma. AB - The etiopathogenesis of infantile haemangioma has not been well understood, and it is accepted that angiogenic mediator dysregulation is the main contributor to the abnormal haemangioma capillary formation. The role of NDRG1, a hypoxia inducible protein; FOXOs, which are tumor suppressor proteins; and the mTOR complex 2 pathway in infantile haemangioma have not been studied yet. The purpose of this study was to investigate NDRG1 and FOXO1 expression in the infantile haemangioma and the correlation of these proteins with proliferation and involution. Primary endothelial cells were obtained, with parental agreement, from 12 infantile haemangioma patients during surgery; 6 patients had proliferating infantile haemangiomas and 6 had involuting IHs. We compared the infantile haemangioma tissues and primary endothelial cells with human vein endothelial cells using microarrays, real-time PCR, Western blotting and immunohistochemical staining. Our data indicated that FOXO1 expression was downregulated in proliferating infantile haemangioma tissue. We found that the expression of NDRG1, a molecule upstream of the FOXO1 pathway, increased during haemangioma proliferation. NDRG1 knockdown decreased haemangioma endothelial cell proliferation and downregulated c-MYC oncoprotein levels. Our findings suggest that NDRG1 positively regulates haemangioma proliferation. FOXO1 dysregulation plays an important role in infantile haemangiomas pathogenesis. PMID- 29569763 TI - New bone formation after transcrestal sinus floor elevation was influenced by sinus cavity dimensions: A prospective histologic and histomorphometric study. AB - OBJECTIVE: The aim of this multicenter prospective study was to analyze clinically and histologically the influence of sinus cavity dimensions on new bone formation after transcrestal sinus floor elevation (tSFE). MATERIAL AND METHODS: Patients needing maxillary sinus augmentation (residual crest height <5 mm) were treated with tSFE using xenogeneic granules. Six months later, bone-core biopsies were retrieved for histological analysis in implant insertion sites. Bucco-palatal sinus width (SW) and contact between graft and bone walls (WGC) were evaluated on cone beam computed tomography, and correlations between histomorphometric and anatomical parameters were quantified by means of forward multiple linear regression analysis. RESULTS: Fifty consecutive patients were enrolled and underwent tSFE procedures, and forty-four were included in the final analysis. Mean percentage of newly formed bone (NFB) at 6 months was 21.2 +/- 16.9%. Multivariate analysis showed a strong negative correlation between SW and NFB (R2 = .793) and a strong positive correlation between WGC and NFB (R2 = .781). Furthermore, when SW was stratified into three groups (<12 mm, 12 to 15 mm, and >15 mm), NFB percentages (36%, 13% and 3%, respectively) resulted significantly different. CONCLUSIONS: This study represented the first confirmation based on histomorphometric data that NFB after tSFE was strongly influenced by sinus width and occurred consistently only in narrow sinus cavities (SW <12 mm, measured between buccal and palatal walls at 10-mm level, comprising the residual alveolar crest).

PMID- 29569765 TI - Induction of IL-10-balanced immune profiles following exposure to LTA from Staphylococcus epidermidis. AB - Staphylococcus epidermidis colonises human skin without apparent inflammation, but a dominance of S. epidermidis and S. aureus is characteristic of cutaneous microbial dysbiosis in atopic dermatitis (AD). While S. aureus can trigger AD, the role of S. epidermidis is less understood. We characterised consequences of innate immune sensing of lipoteichoic acid (LTA) preparations derived from S. epidermidis (epi-LTA) or S. aureus (aureus-LTA). Therefore, dendritic cell (DC) activation and consecutive priming of antigen-specific T cells following exposure of DC to epi-LTA or aureus-LTA were investigated. Mimicking acute AD, exposure of DC to IL-4 and LTAs was analysed. Exposure to epi-LTA or aureus-LTA activated human immune cells and murine dendritic cells (DCs) via TLR2/MyD88, however, resulting in divergent immune profiles. Differences between LTAs were significant for IL-6, IL-12p40 and IL-12p70 but not for IL-10, which was best reflected by the IL-12p70-to-IL-10 ratio being IL-10-balanced for epi-LTA but pro-inflammatory for aureus-LTA. LTA-exposed DCs activated CD4+ T cells; however, while T-cell derived IL-10 was equivalent between LTAs, IFN-gamma and IL-17 were significantly higher for aureus-LTA. Mimicking acute AD by exposing DCs to IL-4 and LTAs revealed that IL-4 significantly and uniformly suppressed epi-LTA-induced cytokine production, keeping the IL-12p70-to-IL-10 ratio balanced. In contrast, exposure of DCs to aureus-LTA and IL-4 enhanced IL-12p70 but suppressed IL-10 levels, further unbalancing the IL-12p70-to-IL-10 ratio. These data demonstrate opposing immune consequences following exposure to staphylococcal LTAs. Epi-LTA induced IL-10-balanced, aureus-LTA pro-inflammatory immune profiles. PMID- 29569766 TI - Lysosomal acid lipase promotes cholesterol ester metabolism and drives clear cell renal cell carcinoma progression. AB - OBJECTIVES: Clear cell renal cell carcinoma (ccRCC) is characterized histologically by accumulation of cholesterol esters, cholesterol and other neutral lipids. Lysosomal acid lipase (LAL) is a critical enzyme involved in the cholesterol ester metabolism. Here, we sought to determine whether LAL could orchestrate metabolism of cholesterol esters in order to promote ccRCC progression. MATERIALS AND METHODS: Quantitative reverse-transcription PCR and western blots were conducted to assess the expression of LAL in human ccRCC tissues. We analysed the relationship between LAL levels and patient survival using tissue microarrays. We used cell proliferation assays, colony formation assays, cell death assays, metabolic assays and xenograft tumour models to evaluate the biological function and underlying mechanisms. RESULTS: LAL was up regulated in ccRCC tissue. Tissue microarray analysis revealed higher levels of LAL in advanced grades of ccRCC, and high LAL expression indicated lower patient survival. Suppressing LAL expression not only blocked the utilization of cholesterol esters but also impaired proliferation and cellular survival. Furthermore, immunohistochemistry staining showed that LAL expression was correlated with Akt phosphorylation. Suppressing LAL expression decreased the phosphorylation level of Akt and Src and reduced the level of 14,15 epoxyeicosatrienoic acids in ccRCC cells. Supplement of 14,15-epoxyeicosatrienoic acids rescued proliferation in vitro and in vivo. CONCLUSIONS: LAL promoted cell proliferation and survival via metabolism of epoxyeicosatrienoic acids and activation of the Src/Akt pathway. PMID- 29569767 TI - Marginal bone loss at implants with different surface characteristics - A 20-year follow-up of a randomized controlled clinical trial. AB - OBJECTIVE: This report is a 20-year follow-up of a randomized controlled clinical trial evaluating the potential long-term effect of a modified implant surface on the preservation of the peri-implant marginal bone level. MATERIAL & METHODS: In each of 51 patients and for each fixed partial denture (FPD), by randomization at least one implant installed had a non-modified turned surface and one a modified and roughened surface (TiOblast(r) ). Clinical and radiological examinations were performed at various follow-up intervals. Primary outcome variables were peri implant marginal bone level change from time of loading and proportion of implants with no bone loss at 20 years. Multilevel analysis followed by nonparametric and Pearson's Chi-Square tests were applied for statistical analysis. RESULTS: At the 20-year follow-up, 25 patients carrying 64 implants were available for evaluation. Turned and TiOblast implants presented with a mean bone level change from the time of FDP delivery amounting to -0.41 mm (95% CI 0.84/0.02) and -0.83 mm (95% CI -1.38/-0.28) respectively (inter-group comparison p > .05). 47% of the Turned and 34% TiOblast implants (p > .05) showed no bone loss. All but one of these implants were free of bacterial plaque and inflammation as well as presented with probing pocket depths <=5 mm at both the 5 and 20-year follow-up examinations. CONCLUSION: It is suggested that a moderate increase of implant surface roughness has no beneficial effect on long-term preservation of the peri-implant marginal bone level. PMID- 29569768 TI - Developing a culturally appropriate branding for a social and emotional wellbeing intervention in an Aboriginal community. AB - ISSUE ADDRESSED: An initial consultation process to implement a culturally appropriate social and emotional wellbeing campaign in an Aboriginal community indicated that the fundamental principles of the Act-Belong-Commit mental health promotion campaign were acceptable, but that a cultural adaptation of the branding should be sought. METHODS: A competition was held inviting community members to design a brand logo for the campaign in their community. Local judges selected "winners" in various categories, and six of the submissions were selected for testing in the broader community via street intercept interviews. Respondents were asked which logo they liked best, their perceived meanings of the designs and the perceived appropriateness of the designs for a social and emotional wellbeing campaign. RESULTS: A convenience sample of N = 26 local Aboriginal people who lived and/or worked in Roebourne completed the questionnaire. There was a clear majority preference for logo "D," which communicated appropriate meanings of pride and strength in standing together, and reflected the underlying strengths and capacities of Aboriginal people which this project seeks to harness and support. CONCLUSIONS: The approach of using a logo competition to develop the campaign brand was highly successful and enabled further meaningful engagement with the community and other service providers in the town. The success of the competition process resulted from an emphasis on relationship building, listening to the local community and involving the community in decision-making. So what? By conforming to established, but not always adhered to, recommendations for community consultation, successful and more enduring outcomes are likely.

AB - BACKGROUND: The Psoriasis Area and Severity Index (PASI) is the standard for psoriasis severity assessment. However, PASI measurement is complex and subjective, frequently leading to a high intra- and interobserver variability. To date, the precise extent of variability in PASI measurements and its underlying causes remain unknown. OBJECTIVE: To determine the inter- and intrarater variability of image-based PASI measurements by calculating Intra-Class Correlation-Coefficients (ICCs) and to investigate the impact of the different PASI components and specific anatomic regions on the extent of variability. METHODS: First, the methodology of 'image-based' vs. commonly used 'live' PASI measurements was validated in a pilot study. Next, in an observational cohort study, PASI scores of 120 patients affected by plaque psoriasis were prospectively evaluated by three formally trained physicians by means of total body images (TBI). Each observer independently performed two rounds of image based PASI calculations in all patients at two different time points. RESULTS: Overall, 720 image-based PASI scores were calculated with a mean PASI of 8.8 (range 0.7-34.8). An interrater variability with an ICC of 0.895 and mean absolute difference (MAD) of 3.3 PASI points were observed. Intrarater variability showed a mean ICC of 0.877 and a MAD of 2.2 points. When considering specific PASI components, the highest agreement was found for the assessment of the involved body surface area (BSA), while the lowest ICCs were calculated for severity scoring of 'scaling' and 'induration'. As BSA scores serve as a multiplier in the calculation of PASI, minor inaccuracies were capable of inducing a large share of variability. CONCLUSION: The overall inter- and intrarater reliability of image-based PASI measurements in this study was good. However, physicians were formally trained and experienced, which frequently is not the case in a real-life clinical setting. Therefore, new strategies for higher standardization and objectivity of PASI calculations are needed. PMID- 29569770 TI - Immediate effects and outcome of in-utero pulmonary valvuloplasty in fetuses with pulmonary atresia with intact ventricular septum or critical pulmonary stenosis. AB - OBJECTIVE: To assess the immediate effects of fetal pulmonary valvuloplasty on right ventricular (RV) size and function as well as in-utero RV growth and postnatal outcome. METHODS: Patients with pulmonary atresia with intact ventricular septum (PAIVS) or critical pulmonary stenosis (CPS) who underwent fetal pulmonary valvuloplasty at our center between October 2000 and July 2017 were included. Echocardiographic data obtained before and after the procedure were analyzed retrospectively (median interval after intervention, 1 (range, 1-3) days) for ventricular and valvular dimensions and ratios, RV filling time (duration of tricuspid valve (TV) inflow/cardiac cycle length), TV velocity time integral (TV-VTI) * heart rate (HR) and tricuspid regurgitation (TR) velocity. Longitudinal data were collected from only those fetuses followed up in our center. Outcome was assessed using the scoring system as described by Roman et al. for non-biventricular outcome. RESULTS: Thirty-five pulmonary valvuloplasties were performed in our institution on 23 fetuses with PAIVS (n = 15) or CPS (n = 8). Median gestational age at intervention was 28 + 4 (range, 23 + 6 to 32 + 1) weeks. No fetal death occurred. Immediately after successful intervention, RV/left ventricular length (RV/LV) ratio (P <= 0.0001), TV/mitral valve annular diameter (TV/MV) ratio (P <= 0.001), RV filling time (P <= 0.00001) and TV-VTI * HR (P <= 0.001) increased significantly and TR velocity (P <= 0.001) decreased significantly. In fetuses followed longitudinally to delivery (n = 5), RV/LV and TV/MV ratios improved further or remained constant until birth. Fetuses with unsuccessful intervention (n = 2) became univentricular, all others had either a biventricular (n = 15), one-and-a-half ventricular (n = 3) or still undetermined (n = 3) outcome. Five of nine fetuses with a predicted non-biventricular outcome, in which the procedure was successful, became biventricular, while two of nine had an undetermined circulation. CONCLUSION: In selected fetuses with PAIVS or CPS, in-utero pulmonary valvuloplasty led immediately to larger RV caused by reduced afterload and increased filling, thus improving the likelihood of biventricular outcome even in fetuses with a predicted non-biventricular circulation.

PMID- 29569771 TI - Identification of the acid-induced degradation products of omeprazole and 5 hydroxyomeprazole by high-resolution mass spectrometry. AB - RATIONALE: Omeprazole is used to treat gastric disorders and is one of the most commonly consumed drugs in the western world. It forms several metabolites but is mostly excreted unchanged and as 5-hydroxyomeprazole. Since omeprazole is widely prescribed, its excretion from the body has a potential environmental effect. After excretion it will enter the wastewater system and if not adequately removed during wastewater treatment will be discharged into rivers in the wastewater effluent. It is important to consider not only the parent drug, but also the main metabolite (5-hydroxyomeprazole) and their degradation products to fully understand the fate of this drug during wastewater treatment. In order to do this potential degradation products need to be determined. METHODS: Acid was used to artificially accelerate the degradation of omeprazole and 5-hydroxyomeprazole. A Q-Exactive Orbitrap mass spectrometer with an electrospray ionisation source was used to determine precursor and product ion data for the degradation products. RESULTS: Both starting materials quickly degrade under acidic conditions and the main degradation product formed in each case was a re-arranged monomer. Other species identified were doubly and singly charged dimers with varying numbers of sulphur atoms in the dimer bridge. Careful inspection of the accurate mass, isotope pattern, isotope abundance and product ion spectra was used to interpret the data. CONCLUSIONS: The resultant degradants from omeprazole and 5 hydroxyomeprazole were analogous to each other, differing only by an oxygen atom. This investigation determined the degradation products of omeprazole and 5 hydroxyomeprazole and proposed structures based on the accurate mass and isotope information. The product ions from the degradation products are also reported. PMID- 29569772 TI - Topical propranolol for infantile haemangiomas: a systematic review. AB - Infantile haemangiomas are the most common tumour of infancy. Whilst the majority are left untreated to involute spontaneously, residual skin changes commonly occur, particularly in superficial haemangiomas. The current first-line treatment for problematic lesions is oral propranolol; however due to the risk of systemic adverse effects, the use of off-label topical preparations has recently been investigated. Our systematic review was conducted in accordance with PRISMA guidelines. Four databases were searched to identify original articles evaluating the use of topical propranolol as the primary therapy for infantile haemangiomas. Twelve articles with a total of 597 patients and 632 haemangiomas were included. Three topical propranolol preparations were used, creams, ointments and gels and were all prepared by local pharmaceutical laboratories. The concentration of propranolol ranged from 0.5% to 5%. Treatment duration ranged from two weeks to 16.5 months. Overall, 90% of lesions improved following the initiation of topical propranolol. A good or excellent response, defined as a reduction in the size of at least 50%, was seen in 59% of lesions. Earlier initiation of treatment (less than 3 months of age) was associated with improved outcomes. No systemic adverse effects were reported. Minor local reactions were seen in 1.3% of patients. Topical propranolol is safer than oral propranolol, though may be less effective. Topical propranolol may be more suitable for patients with small, superficial haemangiomas at risk of cosmetic sequelae, where the cosmetic or symptomatic impact does not warrant oral propranolol treatment.

AB - RATIONALE: Since extraterrestrial organic matter in meteorites is a very complex mixture that is hard to ionize due to its association with minerals, in situ analysis of polar organic compounds has never been performed. In addition, when studying powdered samples, spatial information of organic compounds is lost. METHODS: In situ molecular analysis and chemical imaging of polar organic compounds were performed on a meteorite surface by desorption electrospray ionization coupled with high-resolution mass spectrometry (DESI-HRMS) using an Orbitrap mass spectrometer. RESULTS: Many CHN compounds, including alkylated pyridine and imidazole homologues, were identified from the complex peaks by HRMS using a spray of electrically charged methanol with a spatial resolution of approximately 50 MUm. The same alkylated homologues have the same spatial distribution in the meteorite matrix, while alkylpyridines occur in a different location from alkylimidazoles. CONCLUSIONS: The compound distribution suggests a different source for each compound series or a chromatographic separation effect associated with fluid movement in the meteorite parent body. The DESI-HRMS imaging will further our understanding of organic compound distribution with respect to mineral and water interactions in meteorites. PMID- 29569777 TI - Maternal components of RNA-directed DNA methylation are required for seed development in Brassica rapa. AB - Small RNAs trigger repressive DNA methylation at thousands of transposable elements in a process called RNA-directed DNA methylation (RdDM). The molecular mechanism of RdDM is well characterized in Arabidopsis, yet the biological function remains unclear, as loss of RdDM in Arabidopsis causes no overt defects, even after generations of inbreeding. It is known that 24 nucleotide Pol IV dependent siRNAs, the hallmark of RdDM, are abundant in flowers and developing seeds, indicating that RdDM might be important during reproduction. Here we show that, unlike Arabidopsis, mutations in the Pol IV-dependent small RNA pathway cause severe and specific reproductive defects in Brassica rapa. High rates of abortion occur when seeds have RdDM mutant mothers, but not when they have mutant fathers. Although abortion occurs after fertilization, RdDM function is required in maternal somatic tissue, not in the female gametophyte or the developing zygote, suggesting that siRNAs from the maternal soma might function in filial tissues. We propose that recently outbreeding species such as B. rapa are key to understanding the role of RdDM during plant reproduction. PMID- 29569779 TI - Cytosolic invertases contribute to cellulose biosynthesis and influence carbon partitioning in seedlings of Arabidopsis thaliana. AB - In plants, UDP-glucose is the direct precursor for cellulose biosynthesis, and can be converted into other NDP-sugars required for the biosynthesis of wall matrix polysaccharides. UDP-glucose is generated from sucrose by two distinct metabolic pathways. The first pathway is the direct conversion of sucrose to UDP glucose and fructose by sucrose synthase. The second pathway involves sucrose hydrolysis by cytosolic invertase (CINV), conversion of glucose to glucose-6 phosphate and glucose-1-phosphate, and UDP-glucose generation by UDP-glucose pyrophosphorylase (UGP). Previously, Barratt et al. (Proc. Natl Acad. Sci. USA, 106, 2009 and 13124) have found that an Arabidopsis double mutant lacking CINV1 and CINV2 displayed drastically reduced growth. Whether this reduced growth is due to deficient cell wall production caused by limited UDP-glucose supply, pleiotropic effects, or both, remained unresolved. Here, we present results indicating that the CINV/UGP pathway contributes to anisotropic growth and cellulose biosynthesis in Arabidopsis. Biochemical and imaging data demonstrate that cinv1 cinv2 seedlings are deficient in UDP-glucose production, exhibit abnormal cellulose biosynthesis and microtubule properties, and have altered cellulose organization without substantial changes to matrix polysaccharide composition, suggesting that the CINV/UGP pathway is a key metabolic route to UDP glucose synthesis in Arabidopsis. Furthermore, differential responses of cinv1 cinv2 seedlings to exogenous sugar supplementation support a function of CINVs in influencing carbon partitioning in Arabidopsis. From these data and those of previous studies, we conclude that CINVs serve central roles in cellulose biosynthesis and carbon allocation in Arabidopsis.

AB - ISSUE ADDRESSED: Affordability of a healthy diet is a determinant of nutritional intake and therefore health. This project aimed to measure the cost of healthy foods across a geographically defined region and examine factors related to changing food prices to assist in informing health promotion practice. METHODS: The cost of a healthy food basket was measured using the Victorian Healthy Food Basket tool, in all eligible stores, across five rural local government areas in Western Victoria, Australia in 2014, 2015 and 2016. One-way analysis of variance was used to investigate differences in healthy food basket cost across years. Multivariable linear regression models were constructed to adjust for baseline (2014) cost to determine factors associated with cost. RESULTS: Data were collected from 45 stores in 2014 and 2015 and 48 stores in 2016. The average cost of the healthy food basket was $459 in 2014, $437 in 2015 and $443 in 2016. The cost of the healthy food basket was the highest in stores >15 km from the major regional centre and in areas with only one supermarket (non-cluster) (P < .05). All food groups except fruit and vegetables decreased in price between 2014 and 2016. CONCLUSIONS: This project highlights distance from regional centres and competition as possible factors that influence the cost of healthy food. SO WHAT?: This is valuable insight for health promoters in designing both local level interventions aimed at improving access to healthy food and influencing regional food systems. PMID- 29569783 TI - JRE4 is a master transcriptional regulator of defense-related steroidal glycoalkaloids in tomato. AB - Steroidal glycoalkaloids (SGAs) are specialized anti-nutritional metabolites that accumulate in Solanum lycopersicum (tomato) and Solanum tuberosum (potato). A series of SGA biosynthetic genes is known to be upregulated in Solanaceae species by jasmonate-responsive Ethylene Response Factor transcription factors, including JRE4 (otherwise known as GAME9), but the exact regulatory significance in planta of each factor has remained unaddressed. Here, via TILLING-based screening of an EMS-mutagenized tomato population, we isolated a JRE4 loss-of-function line that carries an amino acid residue missense change in a region of the protein important for DNA binding. In this jre4 mutant, we observed downregulated expression of SGA biosynthetic genes and decreased SGA accumulation. Moreover, JRE4 overexpression stimulated SGA production. Further characterization of jre4 plants revealed their increased susceptibility to the generalist herbivore Spodoptera litura larvae. This susceptibility illustrates that herbivory resistance is dependent on JRE4-mediated defense responses, which include SGA accumulation. Ethylene treatment attenuated the jasmonate-mediated JRE4 expression induction and downstream SGA biosynthesis in tomato leaves and hairy roots. Overall, this study indicated that JRE4 functions as a primary master regulator of SGA biosynthesis, and thereby contributes toward plant defense against chewing insects. PMID- 29569784 TI - The CNPY2 enhances epithelial-mesenchymal transition via activating the AKT/GSK3beta pathway in non-small cell lung cancer. AB - The survival of non-small cell lung cancer (NSCLC) is poor due to high metastasis, and the indispensable step of metastasis includes epithelial mesenchymal transition (EMT). In the study, by analyzing the dataset of the Cancer Genome Atlas (TCGA), we found that the expression of Canopy homolog 2 (CNPY2) is increased both in adenocarcinoma and squamous cell carcinoma, which is further confirmed in NSCLC tissues. Not only that, there is a negative correlation between CNPY2 and E-cadherin expression at mRNA level. Wound healing and transwell matrix penetration assay showed that overexpression of CNPY2 promotes the capability for invasion and metastasis of NSCLC cells. Further analysis uncovered that overexpression of CNPY2 can activate the AKT/GSK3beta pathway, which leads to the inactivation of GSK-3beta. The inactivation of GSK 3beta increases the level of Snail, and then decreases the expression of E cadherin to promote EMT. Eventually, inhibition of AKT suppresses the malignant transformation of CNPY2-upregulated cells. The above results suggest that CNPY2 may be served as a novel therapeutic target to therapy the NSCLC. PMID- 29569785 TI - Sex- and age-adjusted prevalence estimates of five chronic inflammatory skin diseases in France: results of the " OBJECTIFS PEAU " study. AB - BACKGROUND: There are few population-based studies assessing the prevalence of skin diseases. OBJECTIVES: To estimate the prevalence of five chronic skin inflammatory diseases, i.e. atopic dermatitis (AD), psoriasis, alopecia areata (AA), vitiligo and hidradenitis suppurativa (HS) in France, using validated self diagnostic questionnaires. METHODS: Population-based study using a representative sample of the French general population aged more than 15 years and sampling with replacement design. All participants were asked (ii) to fill in a specific questionnaire including socio-demographic characteristics, (ii) to declare if they have been diagnosed with one or more skin problem or skin diseases during their life, and (iii) to fill in five validated self-reported questionnaires for AD, psoriasis, AA, vitiligo and HS. RESULTS: A total of 20.012 adult participants responded to the questionnaire of whom 9760 were men (48.8%) and 10.252 (51.2%) were women. We identified a prevalence of 4.65% for AD (931 individuals), 4.42% for psoriasis (885 individuals), 1.04% for AA (210 individuals), 0.46% for vitiligo (93 individuals) and 0.15% for HS (29 individuals), respectively. LIMITATIONS: Questionnaire-based study and possible disease misclassifications. CONCLUSION: This is the largest population-based study aiming to estimate the prevalence of five chronic skin inflammatory diseases. PMID- 29569786 TI - Propofol prevents IL-13-induced epithelial-mesenchymal transition in human colorectal cancer cells. AB - Accumulating evidence showed that cytokines are involved in the development of cancer. IL-13 was showed to induce epithelial-mesenchymal transition and promote metastasis in colorectal cancer, providing a promising therapeutic target for cancer patients. Interestingly, recent studies showed that propofol, one of most common intravenous anesthetic agent, may have antitumor function in different cancer type. However, the impact of propofol on colorectal cancer and IL-13 induced epithelial-mesenchymal transition remains unknown. Herein, we found that propofol can effectively suppress cell proliferation in colorectal cell lines RKO and SW480 cells by using MTT assay. Furthermore, wound healing assay and migration assay demonstrated that propofol has the ability to inhibit epithelial mesenchymal transition that induced by IL-13 in RKO and SW480 cells. Mechanistically, we found propofol treatment causes up-regulation of miR-361 and miR-135b, that suppress expression of STAT6 and thereafter leads to the inhibition of IL-13/STAT6/ZEB1 signaling pathway. In conclusion, our data for the first time demonstrated that propofol may serve as a novel therapeutic drug for targeting IL-13. The aggressive function of IL-13/STAT6/ZEB1 axis in colorectal cancer was impaired by propofol through miR-361 and miR-135b.

PMID- 29569788 TI - Large uncertainty in carbon uptake potential of land-based climate-change mitigation efforts. AB - Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2 degrees C or less. However, the carbon uptake potential in land-based climate change mitigation efforts is highly uncertain. Here, we address this uncertainty by using two land-based mitigation scenarios from two land-use models (IMAGE and MAgPIE) as input to four dynamic global vegetation models (DGVMs; LPJ-GUESS, ORCHIDEE, JULES, LPJmL). Each of the four combinations of land-use models and mitigation scenarios aimed for a cumulative carbon uptake of ~130 GtC by the end of the century, achieved either via the cultivation of bioenergy crops combined with carbon capture and storage (BECCS) or avoided deforestation and afforestation (ADAFF). Results suggest large uncertainty in simulated future land demand and carbon uptake rates, depending on the assumptions related to land use and land management in the models. Total cumulative carbon uptake in the DGVMs is highly variable across mitigation scenarios, ranging between 19 and 130 GtC by year 2099. Only one out of the 16 combinations of mitigation scenarios and DGVMs achieves an equivalent or higher carbon uptake than achieved in the land-use models. The large differences in carbon uptake between the DGVMs and their discrepancy against the carbon uptake in IMAGE and MAgPIE are mainly due to different model assumptions regarding bioenergy crop yields and due to the simulation of soil carbon response to land use change. Differences between land-use models and DGVMs regarding forest biomass and the rate of forest regrowth also have an impact, albeit smaller, on the results. Given the low confidence in simulated carbon uptake for a given land based mitigation scenario, and that negative emissions simulated by the DGVMs are typically lower than assumed in scenarios consistent with the 2 degrees C target, relying on negative emissions to mitigate climate change is a highly uncertain strategy. PMID- 29569789 TI - Testate amoeba records indicate regional 20th-century lowering of water tables in ombrotrophic peatlands in central-northern Alberta, Canada. AB - Testate amoebae are abundant in the surface layers of northern peatlands. Analysis of their fossilized shell (test) assemblages allows for reconstructions of local water-table depths (WTD). We have reconstructed WTD dynamics for five peat cores from peatlands ranging in distance from the Athabasca bituminous sands (ABS) region in western Canada. Amoeba assemblages were combined with plant macrofossil records, acid-insoluble ash (AIA) fluxes and instrumental climate data to identify drivers for environmental change. Two functional traits of testate amoebae, mixotrophy and the tendency to integrate xenogenic mineral matter in test construction, were quantified to infer possible effects of AIA flux on testate amoeba presence. Age-depth models showed the cores each covered at least the last ~315 years, with some spanning the last millennium. Testate amoeba assemblages were likely affected by permafrost development in two of the peatlands, yet the most important shift in assemblages was detected after 1960 CE. This shift represents a significant apparent lowering of water tables in four out of five cores, with a mean drop of ~15 cm. Over the last 50 years, assemblages shifted towards more xerophilous taxa, a trend which was best explained by increasing Sphagnum s. Acutifolia and, to a lesser extent, mean summer temperature. This trend was most evident in the two cores from the sites located farthest away from the ABS region. AIA flux variations did not show a clear effect on mineral-agglutinating taxa, nor on S. s. Acutifolia presence. We therefore suggest the drying trend was forced by the establishment of S. s. Acutifolia, driven by enhanced productivity following regional warming. Such recent apparent drying of peatlands, which may only be reconstructed by appropriate indicators combined with high chronological control, may affect vulnerability to future burning and promote emissions of CO2 . PMID- 29569790 TI - Hypoxia-Activated Adipose Mesenchymal Stem Cells Prevents Irradiation-Induced Salivary Hypofunction by Enhanced Paracrine Effect Through Fibroblast Growth Factor 10. AB - To explore the effects and mechanisms of paracrine factors secreted from human adipose mesenchymal stem cell (hAdMSCs) that are activated by hypoxia on radioprotection against irradiation-induced salivary hypofunction in subjects undergoing radiotherapy for head and neck cancers. An organotypic spheroid coculture model to mimic irradiation (IR)-induced salivary hypofunction was set up for in vitro experiments. Human parotid gland epithelial cells were organized to form three-dimensional (3D) acinus-like spheroids on growth factor reduced Matrigel. Cellular, structural, and functional damage following IR were examined after cells were cocultured with hAdMSCs preconditioned with either normoxia (hAdMSCNMX ) or hypoxia (hAdMSCHPX ). A key paracrine factor secreted by hAdMSCsHPX was identified by high-throughput microarray-based enzyme-linked immunosorbent assay. Molecular mechanisms and signaling pathways on radioprotection were explored. Therapeutic effects of hAdMSCsHPX were evaluated after in vivo transplant into mice with IR-induced salivary hypofunction. In our 3D coculture experiment, hAdMSCsHPX significantly enhanced radioresistance of spheroidal human parotid epithelial cells, and led to greater preservation of salivary epithelial integrity and acinar secretory function relative to hAdMSCsNMX . Coculture with hAdMSCsHPX promoted FGFR expression and suppressed FGFR diminished antiapoptotic activity of hAdMSCsHPX . Among FGFR-binding secreted factors, we found that fibroblast growth factor 10 (FGF10) contributed to therapeutic effects of hAdMSCsHPX by enhancing antiapoptotic effect, which was dependent on FGFR-PI3K signaling. An in vivo transplant of hAdMSCsHPX into irradiated salivary glands of mice reversed IR-induced salivary hypofunction where hAdMSC-released FGF10 contributed to tissue remodeling. Our results suggest that hAdMSCsHPX protect salivary glands from IR-induced apoptosis and preserve acinar structure and functions by activation of FGFR-PI3K signaling via actions of hAdMSC-secreted factors, including FGF10.

AB - Late-onset HC is a well-recognized complication associated with cyclophosphamide/acrolein-induced toxicity. It poses a management challenge when hyperhydration and bladder irrigation do not result in clinical improvement as desired. The data regarding use of hyperbaric oxygen therapy (HBO2) as an early treatment modality in this clinical setting are limited. We present 2 cases, that were refractory to hyperhydration and bladder irrigation but responded to HBO2. They were treated with 20-30 daily sessions over weekdays with 100% oxygen for 90 minutes at 2 atmospheric pressure units (2 atm). Both patients reported improved symptoms within the first 15 sessions, and hematuria diminished by 20 sessions. Hyperbaric oxygen is a less invasive, outpatient therapy that is effective for treatment of HC and is tolerated well by young patients. PMID- 29569792 TI - Downregulation of miR-491-5p promotes gastric cancer metastasis by regulating SNAIL and FGFR4. AB - Gastric cancer (GC) is among the most fatal cancers in China. MicroRNAs (miRNAs) are versatile regulators during GC development and progression. miR-491-5p has been demonstrated to act as a tumor suppressor in several types of cancer. However, the role of miR-491-5p in GC metastasis remains unknown. Here, we found that miR-491-5p was significantly decreased in GC tissues compared with adjacent non-cancerous tissues, and low miR-491-5p level was associated with large tumor size. Overexpression of miR-491-5p significantly suppressed GC cell epithelial-to mesenchymal transition (EMT) and tumor metastasis in vitro and in vivo. Mechanistically, SNAIL was identified as a direct target of miR-491-5p. The silencing of SNAIL phenocopied the tumor suppressive function of miR-491-5p, whereas re-expression of SNAIL in GC cells rescued the EMT markers and cell migratory ability that were inhibited by miR-491-5p. In addition, miR-491-5p inhibited FGFR4 indirectly. Inhibition of FGFR4 also decreased the SNAIL level and impaired EMT and cell migration. Taken together, these findings indicate that downregulation of miR-491-5p promoted GC metastasis by inducing EMT via regulation of SNAIL and FGFR4. PMID- 29569793 TI - The effect of sleep hygiene education and relaxation exercises on insomnia among postmenopausal women: A randomized clinical trial. AB - AIM: This study used a randomized controlled trial model to determine the effect of progressive relaxation exercises and sleep hygiene training given to postmenopausal women with insomnia. METHODS: A total of 161 postmenopausal women with insomnia were recruited and randomly assigned to experimental (n = 81) and control (n = 80) groups. The experimental group received sleep hygiene and progressive relaxation exercise training, but the control group only received routine health care. The relaxation exercise training was repeated once a week for 8 weeks. The study determined the effect of the intervention on insomnia symptoms. The data were collected between 15 June and 15 September 2015 and evaluated using descriptive statistics, independent samples t-test, chi-squared test, and Cronbach alpha analysis. RESULTS: The mean (SD) score of the experimental group on the Women's Health Initiative Insomnia Rating Scale was 14.03 (3.4) pretest and 7.09 (3.4) posttest. The difference between the pretest and posttest scores was statistically significant (P < .001), as was the difference between the rates of insomnia symptoms between the groups posttest (P < .001). CONCLUSION: The findings of study suggest that nurses teaching progressive relaxation exercises and sleep hygiene would benefit postmenopausal women who suffer from insomnia. PMID- 29569794 TI - Nitrogen deposition outweighs climatic variability in driving annual growth rate of canopy beech trees: Evidence from long-term growth reconstruction across a geographic gradient. AB - In this study, we investigated the role of climatic variability and atmospheric nitrogen deposition in driving long-term tree growth in canopy beech trees along a geographic gradient in the montane belt of the Italian peninsula, from the Alps to the southern Apennines. We sampled dominant trees at different developmental stages (from young to mature tree cohorts, with tree ages spanning from 35 to 160 years) and used stem analysis to infer historic reconstruction of tree volume and dominant height. Annual growth volume (GV ) and height (GH ) variability were related to annual variability in model simulated atmospheric nitrogen deposition and site-specific climatic variables, (i.e. mean annual temperature, total annual precipitation, mean growing period temperature, total growing period precipitation, and standard precipitation evapotranspiration index) and atmospheric CO2 concentration, including tree cambial age among growth predictors. Generalized additive models (GAM), linear mixed-effects models (LMM), and Bayesian regression models (BRM) were independently employed to assess explanatory variables. The main results from our study were as follows: (i) tree age was the main explanatory variable for long-term growth variability; (ii) GAM, LMM, and BRM results consistently indicated climatic variables and CO2 effects on GV and GH were weak, therefore evidence of recent climatic variability influence on beech annual growth rates was limited in the montane belt of the Italian peninsula; (iii) instead, significant positive nitrogen deposition (Ndep ) effects were repeatedly observed in GV and GH ; the positive effects of Ndep on canopy height growth rates, which tended to level off at Ndep values greater than approximately 1.0 g m-2 y-1 , were interpreted as positive impacts on forest stand above-ground net productivity at the selected study sites.

PMID- 29569795 TI - Induction of chemokine (C-C motif) ligand 5 by Epstein-Barr virus infection enhances tumor angiogenesis in nasopharyngeal carcinoma. AB - Nasopharyngeal carcinoma (NPC) is etiologically associated with Epstein-Barr virus (EBV) infection and is known to be highly vascularized. Previous studies have suggested that EBV oncoproteins contribute to NPC angiogenesis. However, the regulatory network of EBV in angiogenesis still remains elusive. Herein, we reveal a novel mechanism of EBV-induced angiogenesis in NPC. First, we showed that EBV-infected NPC cell lines generated larger tumors with more microvessels in mouse xenograft models. Subsequent proteomic analysis revealed that EBV infection increased the expression of a series of angiogenic factors, including chemokine (C-C motif) ligand 5 (CCL5). We then proved that CCL5 was a target of EBV in inducing tumor angiogenesis and growth. Further investigation through transcriptome analysis indicated that the pro-angiogenic function of CCL5 might be mediated by the PI3K/AKT pathway. Furthermore, we confirmed that activation of the PI3K/AKT and hypoxia-inducible factor-1alpha pathways was essential for CCL5 promoted angiogenesis. Finally, the immunohistochemical analysis of human NPC specimens also showed that CCL5 was correlated with angiogenesis. Taken together, our study identifies CCL5 as a key EBV-regulated molecular driver that promotes NPC angiogenesis, suggesting it as a potential therapeutic target.

AB - The fight against vascular disease requires functional endothelial cells (ECs) which could be provided by differentiation of induced Pluripotent Stem Cells (iPS Cells) in great numbers for use in the clinic. However, the great promise of the generated ECs (iPS-ECs) in therapy is often restricted due to the challenge in iPS-ECs preserving their phenotype and function. We identified that Follistatin Like 3 (FSTL3) is highly expressed in iPS-ECs, and, as such, we sought to clarify its possible role in retaining and improving iPS-ECs function and phenotype, which are crucial in increasing the cells' potential as a therapeutic tool. We overexpressed FSTL3 in iPS-ECs and found that FSTL3 could induce and enhance endothelial features by facilitating beta-catenin nuclear translocation through inhibition of glycogen synthase kinase-3beta activity and induction of Endothelin 1. The angiogenic potential of FSTL3 was also confirmed both in vitro and in vivo. When iPS-ECs overexpressing FSTL3 were subcutaneously injected in in vivo angiogenic model or intramuscularly injected in a hind limb ischemia NOD.CB17 Prkdcscid/NcrCrl SCID mice model, FSTL3 significantly induced angiogenesis and blood flow recovery, respectively. This study, for the first time, demonstrates that FSTL3 can greatly enhance the function and maturity of iPS-ECs. It advances our understanding of iPS-ECs and identifies a novel pathway that can be applied in cell therapy. These findings could therefore help improve efficiency and generation of therapeutically relevant numbers of ECs for use in patient-specific cell-based therapies. In addition, it can be particularly useful toward the treatment of vascular diseases instigated by EC dysfunction. Stem Cells 2018;36:1033-1044. PMID- 29569798 TI - Vascular plant-mediated controls on atmospheric carbon assimilation and peat carbon decomposition under climate change. AB - Climate change can alter peatland plant community composition by promoting the growth of vascular plants. How such vegetation change affects peatland carbon dynamics remains, however, unclear. In order to assess the effect of vegetation change on carbon uptake and release, we performed a vascular plant-removal experiment in two Sphagnum-dominated peatlands that represent contrasting stages of natural vegetation succession along a climatic gradient. Periodic measurements of net ecosystem CO2 exchange revealed that vascular plants play a crucial role in assuring the potential for net carbon uptake, particularly with a warmer climate. The presence of vascular plants, however, also increased ecosystem respiration, and by using the seasonal variation of respired CO2 radiocarbon (bomb-14 C) signature we demonstrate an enhanced heterotrophic decomposition of peat carbon due to rhizosphere priming. The observed rhizosphere priming of peat carbon decomposition was matched by more advanced humification of dissolved organic matter, which remained apparent beyond the plant growing season. Our results underline the relevance of rhizosphere priming in peatlands, especially when assessing the future carbon sink function of peatlands undergoing a shift in vegetation community composition in association with climate change. PMID- 29569799 TI - How will climate novelty influence ecological forecasts? Using the Quaternary to assess future reliability. AB - Future climates are projected to be highly novel relative to recent climates. Climate novelty challenges models that correlate ecological patterns to climate variables and then use these relationships to forecast ecological responses to future climate change. Here, we quantify the magnitude and ecological significance of future climate novelty by comparing it to novel climates over the past 21,000 years in North America. We then use relationships between model performance and climate novelty derived from the fossil pollen record from eastern North America to estimate the expected decrease in predictive skill of ecological forecasting models as future climate novelty increases. We show that, in the high emissions scenario (RCP 8.5) and by late 21st century, future climate novelty is similar to or higher than peak levels of climate novelty over the last 21,000 years. The accuracy of ecological forecasting models is projected to decline steadily over the coming decades in response to increasing climate novelty, although models that incorporate co-occurrences among species may retain somewhat higher predictive skill. In addition to quantifying future climate novelty in the context of late Quaternary climate change, this work underscores the challenges of making reliable forecasts to an increasingly novel future, while highlighting the need to assess potential avenues for improvement, such as increased reliance on geological analogs for future novel climates and improving existing models by pooling data through time and incorporating assemblage-level information. PMID- 29569800 TI - Time lag and negative responses of forest greenness and tree growth to warming over circumboreal forests. AB - The terrestrial forest ecosystems in the northern high latitude region have been experiencing significant warming rates over several decades. These forests are considered crucial to the climate system and global carbon cycle and are particularly vulnerable to climate change. To obtain an improved estimate of the response of vegetation activity, e.g., forest greenness and tree growth, to climate change, we investigated spatiotemporal variations in two independent data sets containing the dendroecological information for this region over the past 30 years. These indices are the normalized difference vegetation index (NDVI3g) and the tree-ring width index (RWI), both of which showed significant spatial variability in past trends and responses to climate changes. These trends and responses to climate change differed significantly in the ecosystems of the circumarctic (latitude higher than 67 degrees N) and the circumboreal forests (latitude higher and lower than 50 degrees N and 67 degrees N, respectively), but the way in which they differed was relatively similar in the NDVI3g and the RWI. In the circumarctic ecosystem, the climate variables of the current summer were the main climatic drivers for the positive response to the increase in temperatures showed by both the NDVI3g and the RWI indices. On the other hand, in the circumboreal forest ecosystem, the climate variables of the previous year (from summer to winter) were also important climatic drivers for both the NDVI3g and the RWI. Importantly, both indices showed that the temperatures in the previous year negatively affected the ecosystem. Although such negative responses to warming did not necessarily lead to a past negative linear trend in the NDVI3g and the RWI over the past 30 years, future climate warming could potentially cause severe reduction in forest greenness and tree growth in the circumboreal forest ecosystem.

AB - Patients with attention deficit hyperactivity disorder (ADHD) suffer from poor emotion regulation that might arise from problems in the distribution of attentional resources when confronted with emotional distractors. Previous studies investigating the neurocognitive basis of these problems remain inconclusive. Moreover, most of these studies did not exclude participants with comorbidity, particularly of conduct or oppositional defiant disorder. The aim of this study was to assess alterations in fronto-limbic activation in ADHD adolescents specifically during negative distractors in an emotional attention task. For this purpose, we used functional magnetic resonance imaging to assess 25 boys with noncomorbid ADHD and 25 typically developing (TD) boys while they performed an emotional attention task with positive, negative, and neutral emotional distractors. Boys with ADHD had increased activation relative to TD boys specifically during the negative valenced stimuli in an emotional processing network comprising left anterior insula reaching into the inferior frontal gyrus. The findings suggest altered salience processing in ADHD of negative valenced emotional stimuli that may lead to higher distractibility in ADHD specifically when faced with negative emotional distractors. PMID- 29569802 TI - Explaining the doubling of N2 O emissions under elevated CO2 in the Giessen FACE via in-field 15 N tracing. AB - Rising atmospheric CO2 concentrations are expected to increase nitrous oxide (N2 O) emissions from soils via changes in microbial nitrogen (N) transformations. Several studies have shown that N2 O emission increases under elevated atmospheric CO2 (eCO2 ), but the underlying processes are not yet fully understood. Here, we present results showing changes in soil N transformation dynamics from the Giessen Free Air CO2 Enrichment (GiFACE): a permanent grassland that has been exposed to eCO2 , +20% relative to ambient concentrations (aCO2 ), for 15 years. We applied in the field an ammonium-nitrate fertilizer solution, in which either ammonium (NH4+) or nitrate (NO3-) was labelled with 15 N. The simultaneous gross N transformation rates were analysed with a 15 N tracing model and a solver method. The results confirmed that after 15 years of eCO2 the N2 O emissions under eCO2 were still more than twofold higher than under aCO2 . The tracing model results indicated that plant uptake of NH4+ did not differ between treatments, but uptake of NO3- was significantly reduced under eCO2 . However, the NH4+ and NO3- availability increased slightly under eCO2 . The N2 O isotopic signature indicated that under eCO2 the sources of the additional emissions, 8,407 MUg N2 O-N/m2 during the first 58 days after labelling, were associated with NO3- reduction (+2.0%), NH4+ oxidation (+11.1%) and organic N oxidation (+86.9%). We presume that increased plant growth and root exudation under eCO2 provided an additional source of bioavailable supply of energy that triggered as a priming effect the stimulation of microbial soil organic matter (SOM) mineralization and fostered the activity of the bacterial nitrite reductase. The resulting increase in incomplete denitrification and therefore an increased N2 O:N2 emission ratio, explains the doubling of N2 O emissions. If this occurs over a wide area of grasslands in the future, this positive feedback reaction may significantly accelerate climate change. PMID- 29569803 TI - Elevated CO2 did not affect the hydrological balance of a mature native Eucalyptus woodland. AB - Elevated atmospheric CO2 concentration (eCa ) might reduce forest water-use, due to decreased transpiration, following partial stomatal closure, thus enhancing water-use efficiency and productivity at low water availability. If evapotranspiration (Et ) is reduced, it may subsequently increase soil water storage (DeltaS) or surface runoff (R) and drainage (Dg ), although these could be offset or even reversed by changes in vegetation structure, mainly increased leaf area index (L). To understand the effect of eCa in a water-limited ecosystem, we tested whether 2 years of eCa (~40% increase) affected the hydrological partitioning in a mature water-limited Eucalyptus woodland exposed to Free-Air CO2 Enrichment (FACE). This timeframe allowed us to evaluate whether physiological effects of eCa reduced stand water-use irrespective of L, which was unaffected by eCa in this timeframe. We hypothesized that eCa would reduce tree canopy transpiration (Etree ), but excess water from reduced Etree would be lost via increased soil evaporation and understory transpiration (Efloor ) with no increase in DeltaS, R or Dg . We computed Et , DeltaS, R and Dg from measurements of sapflow velocity, L, soil water content (theta), understory micrometeorology, throughfall and stemflow. We found that eCa did not affect Etree , Efloor , DeltaS or theta at any depth (to 4.5 m) over the experimental period. We closed the water balance for dry seasons with no differences in the partitioning to R and Dg between Ca levels. Soil temperature and theta were the main drivers of Efloor while vapour pressure deficit-controlled Etree , though eCa did not significantly affect any of these relationships. Our results suggest that in the short-term, eCa does not significantly affect ecosystem water-use at this site. We conclude that water-savings under eCa mediated by either direct effects on plant transpiration or by indirect effects via changes in L or soil moisture availability are unlikely in water-limited mature eucalypt woodlands. PMID- 29569804 TI - In Vitro Fusion of Normal and Neoplastic Breast Epithelial Cells with Human Mesenchymal Stroma/Stem Cells Partially Involves Tumor Necrosis Factor Receptor Signaling. AB - Formation of hybrid cells by "accidental cell fusion" of normal and neoplastic breast epithelial cells with local tissue-associated mesenchymal stroma/stem-like cells (MSC) in an inflammatory microenvironment can generate new cancer cell populations whereby molecular signaling mechanisms of this process remain unclear. Fusions of lentiviral enhanced green fluorescent protein-labeled MSC with mcherry-labeled breast epithelial cells were quantified and effects of tumor necrosis factor alpha (TNF-alpha) and receptor downstream signaling were investigated. Cocultures of MSC with normal human mammary epithelial cells, with neoplastic MCF10A, or with MDA-MB-231 or MCF7 breast cancer cells demonstrated hybrid cell formation between 0.1% and about 2% of the populations within 72 hours, whereby the fusion process occurred in less than 5 minutes. Addition of the pro-inflammatory cytokine TNF-alpha significantly enhanced MCF10A-MSC cell fusion. Small-interfering RNA (siRNA) knockdown experiments revealed an involvement of tumor necrosis factor (TNF) receptor-1 and -2 in this process. This was also substantiated by siRNA knockdown of tumor necrosis factor receptor type 1-associated death domain which abolished TNF-alpha-stimulated fusion. While TNF receptor signaling can be relayed via the Mitogen-activated protein kinase 8 (MAPK8), NF-kappaB or cell death pathways, examination of further downstream signaling exhibited little if any effects of MAPK8 or RelA (p65) on TNF-alpha mediated cell fusion, respectively. These data suggested that cell fusion between MSC and MCF10A breast epithelial cells can be stimulated by TNF-alpha involving TNF receptor-activated cell death pathways or additional NF-kappaB signaling.

AB - Mucormycosis is a rare and potentially life-threatening infection, typically affecting immunocompromised hosts. We report a case of an adolescent boy who developed primary isolated cutaneous mucormycosis in the early period following kidney transplantation. Surgical excision was performed using intraoperative fungal staining to obtain clear margins, followed by topical and systemic antifungal therapy. A skin graft was then applied to the excised area with good healing, and the patient made a full recovery. PMID- 29569806 TI - Effect of everolimus on skin lesions in patients treated for subependymal giant cell astrocytoma and renal angiomyolipoma: final 4-year results from the randomized EXIST-1 and EXIST-2 studies. AB - BACKGROUND: Tuberous sclerosis complex (TSC) is a genetic disorder associated with tumour growth in various organs, including the brain, kidneys, heart and skin. Cutaneous lesions are prevalent manifestations of TSC, occurring in up to 90% of patients. Oral mammalian target of rapamycin inhibitors, such as everolimus, is believed to be effective for treatment of TSC-associated lesions because they act on the underlying disease pathophysiology. OBJECTIVE: We evaluated the long-term effect of oral everolimus on TSC-associated skin lesions as a secondary objective in the phase III studies EXIST-1 (NCT00789828) and EXIST 2 (NCT00790400) after approximately 4 years of treatment. MATERIALS AND METHODS: Everolimus was dosed 4.5 mg/m2 /day (titrated to trough 5-15 ng/mL) in patients with TSC-associated subependymal giant cell astrocytoma in EXIST-1, and 10 mg/day initially in adult patients with TSC- or sporadic lymphangioleiomyomatosis associated renal angiomyolipoma in EXIST-2. Following positive results from the core phase, remaining patients were offered open-label everolimus in an extension. Skin lesion response rate was the proportion of patients achieving complete or partial clinical response. RESULTS: A total of 105 patients in EXIST 1 and 107 in EXIST-2 received everolimus and had >=1 skin lesion at baseline. Skin lesion response rate (95% confidence interval) was 58.1% (48.1-67.7%) in EXIST-1 and 68.2% (58.5-76.9%) in EXIST-2; most were partial responses. At week 192 (EXIST-1: n = 55; EXIST-2: n = 56), 69% and 66% had a response. Most common drug-related adverse event was stomatitis (41-45%). CONCLUSION: Oral everolimus improved TSC-related skin lesions, with responses sustained over 4 years of treatment in EXIST-1 and EXIST-2. PMID- 29569807 TI - Coral bleaching is linked to the capacity of the animal host to supply essential metals to the symbionts. AB - Massive coral bleaching events result in extensive coral loss throughout the world. These events are mainly caused by seawater warming, but are exacerbated by the subsequent decrease in nutrient availability in surface waters. It has therefore been shown that nitrogen, phosphorus or iron limitation contribute to the underlying conditions by which thermal stress induces coral bleaching. Generally, information on the trophic ecology of trace elements (micronutrients) in corals, and on how they modulate the coral response to thermal stress is lacking. Here, we demonstrate for the first time that heterotrophic feeding (i.e. the capture of zooplankton prey by the coral host) and thermal stress induce significant changes in micro element concentrations and isotopic signatures of the scleractinian coral Stylophora pistillata. The results obtained first reveal that coral symbionts are the major sink for the heterotrophically acquired micronutrients and accumulate manganese, magnesium and iron from the food. These metals are involved in photosynthesis and antioxidant protection. In addition, we show that fed corals can maintain high micronutrient concentrations in the host tissue during thermal stress and do not bleach, whereas unfed corals experience a significant decrease in copper, zinc, boron, calcium and magnesium in the host tissue and bleach. In addition, the significant increase in delta65 Cu and delta66 Zn signature of symbionts and host tissue at high temperature suggests that these isotopic compositions are good proxy for stress in corals. Overall, present findings highlight a new way in which coral heterotrophy and micronutrient availability contribute to coral resistance to global warming and bleaching.

PMID- 29569808 TI - A voxel-based asymmetry study of the relationship between hemispheric asymmetry and language dominance in Wada tested patients. AB - Determining the anatomical basis of hemispheric language dominance (HLD) remains an important scientific endeavor. The Wada test remains the gold standard test for HLD and provides a unique opportunity to determine the relationship between HLD and hemispheric structural asymmetries on MRI. In this study, we applied a whole-brain voxel-based asymmetry (VBA) approach to determine the relationship between interhemispheric structural asymmetries and HLD in a large consecutive sample of Wada tested patients. Of 135 patients, 114 (84.4%) had left HLD, 10 (7.4%) right HLD, and 11 (8.2%) bilateral language representation. Fifty-four controls were also studied. Right-handed controls and right-handed patients with left HLD had comparable structural brain asymmetries in cortical, subcortical, and cerebellar regions that have previously been documented in healthy people. However, these patients and controls differed in structural asymmetry of the mesial temporal lobe and a circumscribed region in the superior temporal gyrus, suggesting that only asymmetries of these regions were due to brain alterations caused by epilepsy. Additional comparisons between patients with left and right HLD, matched for type and location of epilepsy, revealed that structural asymmetries of insula, pars triangularis, inferior temporal gyrus, orbitofrontal cortex, ventral temporo-occipital cortex, mesial somatosensory cortex, and mesial cerebellum were significantly associated with the side of HLD. Patients with right HLD and bilateral language representation were significantly less right handed. These results suggest that structural asymmetries of an insular-fronto temporal network may be related to HLD.

PMID- 29569811 TI - A novel podoplanin-GFPCre mouse strain for gene deletion in lymphatic endothelial cells. AB - The lymphatic vascular system is a one-direction network of thin-walled capillaries and larger vessels covered by a continuous layer of endothelial cells responsible for maintaining fluid homeostasis. Some of the main functions of the lymphatic vasculature are to drain fluid from the extracellular spaces and return it back to the blood circulation, lipid absorption from the intestinal tract, and transport of immune cells to lymphoid organs. A number of genes controlling the development of the mammalian lymphatic vasculature have been identified in the last few years, and their functional roles started to be characterized using gene inactivation approaches in mice. Unfortunately, only few mouse Cre strains relatively specific for lymphatic endothelial cells (LECs) are currently available. In this article, we report the generation of a novel Podoplanin (Pdpn) GFPCre transgenic mouse strain using its 5' regulatory region. Pdpn encodes a transmembrane mucin-type O-glycoprotein that is expressed on the surface of embryonic and postnatal LECs, in addition to few other cell types. Our detailed characterization of this novel strain indicates that it will be a valuable additional genetic tool for the analysis of gene function in LECs. PMID- 29569812 TI - Ofatumumab in post-transplantation recurrence of a pediatric steroid-resistant idiopathic nephrotic syndrome. AB - Treatment of SRNS is a challenge. Antiproliferative agents and depleting antibodies have been reported to be effective. However, these agents are not always successful, and use of ofatumumab could provide a different treatment option. Our patient was diagnosed with a SRNS at 5 years of age. She developed ESRD, with FSGS. This was cause for a first renal transplantation. The NS relapsed, leading to loss of the graft, and a second renal transplantation was performed. Due to the recurrence of the NS, IAds were initiated and led to a complete remission. Our patient remained dependent on IAds, however, despite treatments with calcineurin inhibitors, corticosteroids, rituximab, and abatacept. Ofatumumab was introduced and led to a remission, thus allowing cessation of the IAd treatment. Another infusion of ofatumumab was administered 8 months after the last one, due to the recurrence of the NS and a renewed increase in B cells. Although it did not result in a complete remission, the proteinuria was stabilized in the absence of IAds. Ofatumumab may be an alternative treatment for post-transplantation rituximab-resistant SRNS, although this needs to be confirmed by further studies. PMID- 29569813 TI - Prospective monitoring of adenovirus infection and type analysis after allogeneic hematopoietic cell transplantation: A single-center study in Korea. AB - BACKGROUND: Epidemiologic studies of human adenovirus (HAdV) in allogeneic hematopoietic cell transplantation (HCT) recipients have been conducted mostly in European countries where HAdV 2 (species C) has been most prevalent in the community. The main objective of this study was to investigate the epidemiology and the characteristics of HAdV infection in Korean allogeneic HCT recipients (<19 years). METHODS: In a prospective study from April 2012 to September 2015, HAdV in blood, urine, and stool specimens were monitored weekly from transplantation to day 100 or after if clinically suspected. HAdV infection was defined as positive HAdV PCR result in any specimens regardless of symptoms. RESULTS: A total of 1734 specimens were collected from 57 consecutively enrolled recipients. The cumulative incidence of HAdV infection at day 100, and 1 year was 10%, and 20%, and the incidence of viremia was 2% and 6%, respectively. The median onset time from HCT to viremia was 221 days (range, 7-596 days). All viremia cases were caused by only HAdV 3 (species B), whereas several types were detected in stool. Among patients with HAdV infection, lower absolute lymphocyte counts and extensive chronic graft-vs-host disease were associated with viremia (P = .028 and P = .006, respectively). CONCLUSIONS: Compared to western studies, this study demonstrated a lower incidence and delayed onset of HAdV infections and HAdV 3 was most prevalent in Korea. PMID- 29569814 TI - Molecular cloning, characterization, and expression profiles of the Sox3 gene in Chinese loach Paramisgurnus dabryanus. AB - A number of studies have established that in vertebrates, Sox3 is involved in a wide range of developmental processes, including sex differentiation and neurogenesis. However, the exact functions of the Sox3 gene have not been documented so far in teleosts. Here, we cloned the full length cDNA of Sox3 from the teleost fish, Paramisgurnus dabryanus, which we designated PdSox3. Sequence analysis revealed that PdSox3 encodes a hydrophilic protein, and shares high homology with Sox3 in other species, ranging from mammals to fishes. Quantitative real-time reverse transcription PCR, and in situ hybridization showed that PdSox3 is consistently expressed during embryogenesis, mainly localized in the developing central nervous system. Tissue distribution analyses revealed that PdSox3 is abundant in the adult brain, especially in particle cell layer. Furthermore, PdSox3 expression was higher in gonads, in primary spermatocyte cells, primary oocytes, and previtellogenic oocyte cells. All of these results suggest that PdSox3 plays an important role in early embryonic development, in particular the formation and development of the nervous system, and gonad development, similarly to other vertebrates. This is the first report describing Sox3 gene expression from this species, and the results are necessary to provide fundamental information on both the functional and evolutionary role of Sox3 across different species.

PMID- 29569816 TI - Big (Bio)Chemical Data Mining Using Chemometric Methods: A Need for Chemists. AB - This review aims to demonstrate abilities to analyze Big (Bio)Chemical Data (BBCD) with multivariate chemometric methods and to show some of the more important challenges of modern analytical researches. In this review, the capabilities and versatility of chemometric methods will be discussed in light of the BBCD challenges that are being encountered in chromatographic, spectroscopic and hyperspectral imaging measurements, with an emphasis on their application to omics sciences. In addition, insights and perspectives on how to address the analysis of BBCD are provided along with a discussion of the procedures necessary to obtain more reliable qualitative and quantitative results. In this review, the importance of Big Data and of their relevance to (bio)chemistry are first discussed. Then, analytical tools which can produce BBCD are presented as well as some basics needed to understand prospects and limitations of chemometric techniques when they are applied to BBCD are given. Finally, the significance of the combination of chemometric approaches with BBCD analysis in different chemical disciplines is highlighted with some examples. In this paper, we have tried to cover some of the applications of big data analysis in the (bio)chemistry field. However, this coverage is not extensive covering everything done in the field. PMID- 29569817 TI - In vitro and in vivo evaluation of novel biodegradable Mg-Ag-Y alloys for use as resorbable bone fixation implant. AB - Magnesium (Mg) alloy is gaining more interest because of its degradability and osteogenic potential. Still, it has some deficiencies, such as its rapid degradation rate, insufficient mechanical property. This research aimed to design a novel biodegradable Mg-argentum (Ag)-yttrium (Y) alloy, and Y was added to improve degradable and mechanical property. Mg-Ag-Y alloys were characterized for mechanical features, practicabilities in vitro and in vivo. The mechanical features results shown that this novel component was similar to native bone tissue in elastic moduli, tensile, and compressive stress. Then mesenchymal stem cells (MSCs) were seeded in alloys to assess cell toxicity in vitro. The results showed that its aqueous extract was suitable for MSCs adhesion and proliferation. Then the alloy was evaluated for biomedical applications in nonfractured distal femora of Sprague Dawley rats for 6 weeks, compared with those of pure-Mg and stainless steel groups. All rats survived, and hematological and histological evaluation showed no abnormal physiology 6 weeks postimplantation, and measurements of serum Mg2+ concentration were within normal levels. X-ray scanning, microcomputed tomography, and histological examinations were performed to evaluate the degradability and osteogenic potential. The results indicated that the degradation rate of alloy was 0.91 mm per year, (range 0.77-1.22 mm), and pure-Mg 1.80 mm per year (1.43-2.26 mm). The new bone quantity was 3.18 mm3 (1.46-4.44 mm3 ) in Mg-Ag-Y alloys group, 1.39 mm3 (0.54-2.32 mm3 ) in pure-Mg group, and none in stainless steel group. These promising results suggest potential clinical application of Mg-Ag-Y alloys for use as resorbable bone fixation implant. (c) 2018 Wiley Periodicals, Inc.

AB - The utility of plant functional traits for predictive ecology relies on our ability to interpret trait variation across multiple taxonomic and ecological scales. Using extensive data sets of trait variation within species, across species and across communities, we analysed whether and at what scales leaf economics spectrum (LES) traits show predicted trait-trait covariation. We found that most variation in LES traits is often, but not universally, at high taxonomic levels (between families or genera in a family). However, we found that trait covariation shows distinct taxonomic scale dependence, with some trait correlations showing opposite signs within vs. across species. LES traits responded independently to environmental gradients within species, with few shared environmental responses across traits or across scales. We conclude that, at small taxonomic scales, plasticity may obscure or reverse the broad evolutionary linkages between leaf traits, meaning that variation in LES traits cannot always be interpreted as differences in resource use strategy. PMID- 29569819 TI - Outlier experienced surgeon's performances impact on benchmark for technical surgical skills training. AB - BACKGROUND: Training in medicine must move to an outcome-based approach. A proficiency-based progression outcome approach to training relies on a quantitative estimation of experienced operator performance. We aimed to develop a method for dealing with atypical expert performances in the quantitative definition of surgical proficiency. METHODS: In study one, 100 experienced laparoscopic surgeons' performances on virtual reality and box-trainer simulators were assessed for two similar laparoscopic tasks. In study two, 15 experienced surgeons and 16 trainee colorectal surgeons performed one simulated hand-assisted laparoscopic colorectal procedure. Performance scores of experienced surgeons in both studies were standardized (i.e. Z-scores) using the mean and standard deviations (SDs). Performances >1.96 SDs from the mean were excluded in proficiency definitions. RESULTS: In study one, 1-5% of surgeons' performances were excluded having performed significantly below their colleagues. Excluded surgeons made significantly fewer correct incisions (mean = 7 (SD = 2) versus 19.42 (SD = 4.6), P < 0.0001) and a greater proportion of incorrect incisions (mean = 45.71 (SD = 10.48) versus 5.25 (SD = 6.6), P < 0.0001). In study two, one experienced colorectal surgeon performance was >4 SDs for time to complete the procedure and >6 SDs for path length. After their exclusions, experienced surgeons' performances were significantly better than trainees for path length: P = 0.031 and for time: P = 0.002. CONCLUSION: Objectively assessed atypical expert performances were few. Z-score standardization identified them and produced a more robust quantitative definition of proficiency. PMID- 29569820 TI - Can pathological reports of rectal cancer provide national quality indicators? AB - BACKGROUND: Rectal cancer care has become increasingly complex and requires accurate information. The pathology report is a vital tool for accessing information to gauge a patient's prognosis and to guide treatment decisions. The aim of this study was to assess the quality of histopathological reporting and surgery for rectal cancer in New Zealand using defined quality indicators. METHODS: This is a retrospective audit of pathological reports of all resected rectal cancer pathology reports submitted to the New Zealand Cancer Registry (NZCR) in 2015. The quality of reporting was assessed using specified criteria: synoptic report, adequate lymph node retrieval, reporting of circumferential resection margin (CRM) and mesorectal excision quality. Surgical outcomes were sphincter preservation rate, CRM clearance and complete mesorectal excision. RESULTS: A total of 803 patients with rectal cancer were reported to the NZCR in 2015, 505 underwent proctectomy. A total of 89.5% of reports were structured, 81.8% reported mesorectal excision quality and 86.7% reported CRM status. Adequate lymph node retrieval was obtained in 65.1%, complete mesorectal excision in 84.6% and positive CRM in 6.2% of cases. Quality varied between laboratories and district health boards. High-volume laboratories had higher quality reporting. Surgeon volume and training was related to adequate lymph node retrieval but not CRM clearance nor mesorectal excision quality. CONCLUSION: High quality pathological reporting is associated with the use of synoptic reporting templates. Surgical outcomes for rectal cancer in New Zealand, especially the low rate of CRM involvement, compare favourably with international audits. PMID- 29569821 TI - Efficacy and possible mechanisms of Botulinum Toxin type A on hypertrophic scarring. AB - BACKGROUND: Clinical observations indicate that Botulinum toxin type A (BTXA) can inhibit the growth and improve the eventual appearance of hypertrophic scarring. However, the molecular mechanism remains unclear. OBJECTIVE: We used human keloid fibroblasts to investigate the molecular mechanism of BTXA on hypertrophic scarring. METHODS: Different concentrations of BTXA (0.01, 0.1, 1, and 10 U/L) were used to treat keloid fibroblasts. Changes in cellular morphology, viability, proliferation, cell cycle, and apoptosis were observed by immunofluorescence, MTT assay, and flow cytometry. In addition, real-time qPCR and Western blotting were used to explore the potential molecular mechanisms. RESULTS: Keloid fibroblast viability decreased with increasing BTXA dose. After BTXA treatment, the volume of keloid fibroblasts cells increased, but the nucleus of cells shrunk. Long thin dendrites were formed as the concentration of BTXA increased. Furthermore, the proliferation and S phase of keloid fibroblasts were inhibited by BTXA. Matrix metalloproteinase (, MMP)-1 and -2 RNA and protein showed high expression, but TGF-beta1 and MMP-9 showed low expression than the control. CONCLUSION: Botulinum toxin type A may promote the healing of scars by inhibiting the proliferation of keloid fibroblasts and regulating the expression of TGF-beta1, which could affect the expression of MMP-1 and MMP-2. This study provides theoretical support for the clinical application of BTXA to control hypertrophic scarring.

AB - BACKGROUND: Vulvodynia is the most common type of chronic pelvic pain and dyspareunia in premenopausal women. The effect of drugs for the treatment of vulvodynia remains poorly discussed. OBJECTIVES: To conduct a systematic review of randomised controlled studies which assess medications used to treat vulvar pain in vulvodynia. SEARCH STRATEGY: Web of Science, Cochrane Library, EBSCO Academic, LILACS and MEDLINE were searched from 1985 to September 2016. SELECTION CRITERIA: Randomised controlled trials comparing any kind of medication for vulvodynia treatment with placebo or with another medication in adult patients were included. DATA COLLECTION AND ANALYSIS: The two investigators independently conducted data extraction. The synthesis was provided by the pain reduction index. Study quality assessment was performed using the Cochrane Handbook for Systematic Reviews of Intervention and analysis of publication bias was conducted. MAIN RESULTS: Five studies were included in qualitative synthesis. Number of participants varied from 30 to 133 participants among the eligible studies, resulting in a total of 297 patients. The pain reduction rates of patients with vulvodynia assessed by Q-tipped cotton test and visual analogue scale varied between studies. Placebo was shown to be as effective as any medication. CONCLUSIONS: There is a need for further studies evaluating topical monotherapy for the treatment of vulvodynia, as they are the main drugs used in clinical practice. TWEETABLE ABSTRACT: No medication has shown impact on vulvar pain in vulvodynia. There is evidence of a placebo effect.

AB - Molecular-level airborne sensing is critical for early prevention of disasters, diseases, and terrorism. Currently, most 2D surface-enhanced Raman spectroscopy (SERS) substrates used for air sensing have only one functional surface and exhibit poor SERS-active depth. "Aerosolized plasmonic colloidosomes" (APCs) are introduced as airborne plasmonic hotspots for direct in-air SERS measurements. APCs function as a macroscale 3D and omnidirectional plasmonic cloud that receives laser irradiation and emits signals in all directions. Importantly, it brings about an effective plasmonic hotspot in a length scale of approximately 2.3 cm, which affords 100-fold higher tolerance to laser misalignment along the z axis compared with 2D SERS substrates. APCs exhibit an extraordinary omnidirectional property and demonstrate consistent SERS performance that is independent of the laser and analyte introductory pathway. Furthermore, the first in-air SERS detection is demonstrated in stand-off conditions at a distance of 200 cm, highlighting the applicability of 3D omnidirectional plasmonic clouds for remote airborne sensing in threatening or inaccessible areas.

AB - OBJECTIVE: To determine whether the recovery window (RW) between neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) affects 90-day postoperative morbidity and incidence of lymph node metastasis. PATIENTS AND METHODS: We reviewed patients treated with NAC and RC from 1995 to 2013 for <=cT4 N0 M0 bladder cancer. The association of the RW with 90-day perioperative morbidity and lymph node metastasis was determined. Generalised linear models were used to determine predictors of each endpoint. Patients were stratified into four RWs by 21-day intervals (18-42; 43-63; 64-84; and >=85 days) from last day of NAC to RC. RESULTS: We evaluated 306 patients with RW information during the study period. The median (range) RW was 46 (18-199) days. There was no difference in overall morbidity, re-admission, or major complication rates amongst the four RWs. In the multivariable analysis extravesical disease was an independent predictor of overall morbidity (odds ratio [OR] 1.95, 95% confidence interval [CI] 1.16-3.26; P = 0.011). Age (OR 1.05, 95% CI: 1.02-1.09; P = 0.004), and surgical duration >=7 h (OR 2.87, 95% CI: 1.52-5.42; P = 0.001) were independent predictors of major complications. Only surgical duration >=7 h was a predictor of re-admission (OR 2.24; 95% CI: 1.26-3.98; P = 0.006). A RW of >=85 days had the highest incidence of node-positive disease (pN+; 40%). In a separate multivariable model that included clinical predictors for pN+, a RW of >=85 days was an independent predictor of nodal metastasis (OR 2.92, 95% CI: 1.20-7.09; P = 0.018). CONCLUSION: Patients treated with NAC for bladder cancer can undergo RC between 18 and 84 days (2.5-12 weeks) after NAC with no difference in the risk of perioperative morbidity. Delaying surgery beyond 12 weeks was associated with a significant risk of lymph node metastasis.

AB - Previous studies revealed that the promoters for driving both Cas9 and sgRNAs are quite important for efficient genome editing by CRISPR/Cas9 in plants. Here, we report our results of targeted genome editing using the maize dmc1 gene promoter combined with the U3 promoter for Cas9 and sgRNA, respectively. Three loci in the maize genome were selected for targeting. The T0 plants regenerated were highly efficiently edited at the target sites with homozygous or bi-allelic mutants accounting for about 66%. The mutations in T0 plants could be stably transmitted to the T1 generation, and new mutations could be generated in gametes or zygotes. Whole-genome resequencing indicated that no off-target mutations could be detected in the predicted loci with sequence similarity to the targeted site. Our results show that the dmc1 promoter-controlled (DPC) CRISPR/Cas9 system is highly efficient in maize and provide further evidence that the optimization of the promoters used for the CRISPR/Cas9 system is important for enhancing the efficiency of targeted genome editing in plants. The evolutionary conservation of the dmc1 gene suggests its potential for use in other plant species.

AB - A telomerase-responsive DNA icosahedron was designed to precisely release caged platinum nanodrugs into cisplatin-resistance tumor cells for effective therapy. This DNA icosahedron was constructed from two pyramidal DNA cages connected with telomerase primers and telomeric repeats, and platinum nanodrugs were then encapsulated into the DNA structure. In the presence of telomerase, the primers are extended, leading to inner-chain substitution of the DNA icosahedron and subsequent release of the caged nanodrugs. This DNA icosahedron can precisely release caged nanodrugs in response to telomerase in tumor cells, giving enhanced anticancer efficacy in drug-resistant carcinoma and with reduced toxicity to normal tissues. We speculate that this precisely designed, well controlled DNA cage could be generalized to diverse anticancer drugs. PMID- 29569828 TI - The kinetics and mechanism of bone morphogenetic protein 2 release from calcium phosphate-based implant-coatings. AB - Biomimetically deposited calcium phosphate-based coatings of prostheses can serve as a vehicle for the targeted delivery of growth factors to the local implant environment. Based on indirect evidence in previous studies we hypothesize that such agents are liberated gradually from the coating via a cell-mediated degradation. In the present study, we tested this hypothesis by investigating the release mechanism and its kinetics by use of a radiolabeled osteogenic agent (131 I-BMP-2) under conditions in which native cell populations with a coating degradative potential were either absent or present. The release of 131 I-BMP-2 was monitored for 5 weeks, either in vitro or after implantation at an ectopic (subcutaneous) site in rats in vivo. Only from implants that bore a coating incorporated depot of bone morphogenetic protein 2 (BMP-2) was the agent released slowly and steadily over 5 weeks, that is, 50% of the loaded dose was liberated in vivo (5 to 10% weekly), as against 14.6% in vitro (less than 1% weekly). The coatings bearing an incorporated depot of BMP-2 underwent significant cell mediated degradation, whereas under cell-free conditions no degradation occurred, and the spontaneous release of BMP-2 was negligible. Our findings confirm this carrier system to be a suitable vehicle for the sustained and cell-mediated delivery of BMP-2. (c) 2018 Wiley Periodicals, Inc.

AB - Induced pluripotent stem cells (iPSCs) stand to revolutionize the way we study human development, model disease, and eventually, treat patients. However, these cell sources produce progeny that retain embryonic and/or fetal characteristics. The failure to mature to definitive, adult-type cells is a major barrier for iPSC based disease modeling and drug discovery. To directly address these concerns, we have developed a chemically defined, serum and feeder-free-directed differentiation platform to generate hematopoietic stem-progenitor cells (HSPCs) and resultant adult-type progeny from iPSCs. This system allows for strict control of signaling pathways over time through growth factor and/or small molecule modulation. Through direct comparison with our previously described protocol for the production of primitive wave hematopoietic cells, we demonstrate that induced HSPCs are enhanced for erythroid and myeloid colony forming potential, and strikingly, resultant erythroid-lineage cells display enhanced expression of adult beta globin indicating definitive pathway patterning. Using this system, we demonstrate the stage-specific roles of two key signaling pathways, Notch and the aryl hydrocarbon receptor (AHR), in the derivation of definitive hematopoietic cells. We illustrate the stage-specific necessity of Notch signaling in the emergence of hematopoietic progenitors and downstream definitive, adult-type erythroblasts. We also show that genetic or small molecule inhibition of the AHR results in the increased production of CD34+ CD45+ HSPCs while conversely, activation of the same receptor results in a block of hematopoietic cell emergence. Results presented here should have broad implications for hematopoietic stem cell transplantation and future clinical translation of iPSC-derived blood cells. Stem Cells 2018;36:1004-1019. PMID- 29569830 TI - The efficacy and complications of a new technique of Abobotulinum-toxin A (Dysport) injection in patients with glabellar lines. AB - BACKGROUND: Abobotulinum- toxin A is used extensively for the treatment of frown (glabellar) lines. AIMS: The aim of this study was to evaluate the efficacy and complications of a new injection technique and to assess the amount of satisfaction in patients with the frown lines. METHODS: This cross-sectional study was conducted in 104 patients with moderate-to-severe glabellar lines. In the new technique by reassessing the responsible anatomic muscles of wrinkles, we tried to modify the injection technique of Abobotulinum-toxin A to yield more favorable results. The range and severity of frown lines were assessed by a 4 score test and a photograph taken before and 2 weeks after the injection. Patients were followed up to 180 days after injection. RESULTS: The response time of 87.5% of patients was within the first 48 hours and the remaining 12.5% showed the symptoms within the first week after injection. At 30 days after injection, the frown lines had disappeared in 88.5% of patients in static mode and 85.6% in mechanic mode. Maximum injection durability in the first 3, 4, and 6 months after injection was 82%, 52%, and 38%, respectively. The amount of complete satisfaction after 3 months was reported to be 86.5%. CONCLUSIONS: This study indicated that the new injection technique of Abobotulinum-toxin A could be beneficial in the treatment of frown lines with more satisfactory results, especially in those patients who were not contented with the present conventional method.

AB - There has been significant progress in the self-assembly of biological materials, but the one-step covalent peptide self-assembly for well-defined nanostructures is still in its infancy. Inspired by the biological functions of tyrosine, a covalently assembled fluorescent peptide nanogel is developed by a ruthenium mediated, one-step photo-crosslinking of tyrosine-rich short peptides under the visible light within 6 minutes. The covalently assembled peptide nanogel is stable in various organic solvents and different pH levels, unlike those made from vulnerable non-covalent assemblies. The semipermeable peptide nanogel with a high density of redox-active tyrosine acts as a novel nano-bioreactor, allowing the formation of uniform metal-peptide hybrids by selective biomineralization under UV irradiation. As such, this peptide nanogel could be useful in the design of novel nanohybrids and peptidosomes possessing functional nanomaterials.

AB - Early loss of grafted islets is the main obstacle to achieve favorable outcomes of islet transplantation. Mesenchymal stem cells are known to have a protective effect; however, its mechanism remains unclear. We hypothesized that bone marrow derived mesenchymal stem cells (BMSCs) can protect grafted islets against endoplasmic reticulum stress (ERS)-induced apoptosis. In syngeneic streptozocin induced diabetic BALB/c mice, islet grafts decreased blood glucose levels; however, the effect was not fully functional from the immediate post-transplant phase. beta-Cell apoptosis was proven on days 1 and 3 after transplantation. Ultra-structural evidence of ERS was observed along with increased expressions of marker protein BIP and apoptosis-related protein CHOP. In contrast, BMSC co transplantation maintained glucose hemostasis, inhibited apoptosis and alleviated ERS. In ex vivo culture, BMSCs improved viability of islets and decreased apoptosis. Increased ERS were observed in cultured islets exposed to hypoxia, but not in the islets cocultured with BMSCs. Furthermore, cocultured BMSCs protected islets against ERS-induced apoptosis as well as improved their insulin secretion, and BMSCs alleviated ERS by improving Myc expression through both stromal cell derived factor 1 signal and contact effect. In conclusion, BMSCs protected the grafted islets against ERS-induced apoptosis during the early stage after transplantation. This study opens a new arena for ERS-targeted therapy to improve outcomes of islet transplantation. Stem Cells 2018;36:1045-1061.

AB - In this study, a d-limonene nanoemulsion was developed by using a spontaneous emulsification method and its potential to inhibit the quorum sensing (QS) regulated properties of Escherichia coli O157:H7 (E. coli) were revealed. The results in this study showed that d-limonene nanoemulsion inhibited E. coli biofilm formation through the suppression of curli and extracellular polymeric substance (EPS) production without inhibiting cell growth, and decreased swimming and swarming ability. Further analyses showed that d-limonene nanoemulsion interfered with auto-inducer 2 (AI-2) communication and repressed the expression of curli related genes and AI-2 importer genes in E. coli.

AB - Recently, injectable hydrogel/microparticle systems have so considered for tissue engineering and regenerative medicine. In this study, we produced an injectable in situ self-crosslinked hydrogel/microparticle system for simultaneous dual drug delivery. First, melatonin conjugated chitosan microparticle loaded with methylprednisolone (MCC-MP) microparticle was fabricated by the covalent linkage of melatonin to chitosan by N-hydroxysuccinimide (NHS)1-Ethyl-3-(3-dimethylamino propyl)-carbodiimide (EDC) followed by an ionic gelation of MCC and MP using tripolyphosphate (TPP). Second, the hydrogel was prepared by the connection between the aldehyde group of alginate oxide (AD) and the amine group belonging to carboxymethyl chitosan (CMC) via Schiff base reaction. Finally, microparticle was incorporated into the AD-CMC hydrogel to produce a hydrogel/microparticle system. Hydrogel/microparticle was assessed by many techniques including microscopy, spectroscopy, particle size measurements, mechanical analysis, injectability, rheological analyses to ascertain hydrogel/microparticle properties. The biological assays of mesenchymal stem cells (MSCs) culture, 3 (4,5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), acridine orange/propidium iodide (AO/PI), and 4, 6-diamidino-2-phenylindole (DAPI) to assess cell viability and dimethylmethylene blue (DMMB) to evaluate proteoglycan content were done. The release profiles of melatonin and MP showed acceptable release after 60 and 20 days, respectively. The hydrogel/microparticle system has the ability to sustain cells alive. A higher rate of proteoglycan content was observed in hydrogel/microparticle as compared with hydrogel. With appropriate biocompatibility and adequate properties, this system can be a proper alternative for cartilage tissue engineering. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: With aging, the ability to generate muscle force decreases, contributing to declines in physical functions such as walking. While most studies assess muscle force by peak torque, the rate of torque development (RTD) reflects a dynamic component of muscle performance that is important for physical function. Using data from the Baltimore Longitudinal Study of Aging, we assessed whether RTD adds significantly to peak torque in associations with lower extremity performance. If so, RTD may help identify weak older adults for screening and intervention. METHODS: We assessed associations of RTD and peak torque with physical performance independent of demographics, BMI, body composition, and each other in 1089 Baltimore Longitudinal Study of Aging participants (49.7% women; aged 26 to 96 years; women, 64.0 +/- 13.8 years; men, 68.4 +/- 14.4 years). Peak torque was assessed by isometric and 30 deg/s isokinetic knee extension tests. Peak RTD was operationalized as the maximum torque-time slope among successive 50 ms epochs over the first 3 s of a test of knee extension isometric strength, with the knee joint positioned at 120 deg of flexion. A battery of lower extremity performance tests included gait speed during a 6 m walk at usual and fast pace (6 m usual and fast), time to complete a 400 m walk at fast pace (400 m), distance covered in a 2.5 min walk at normal pace (2.5 min), time to complete 5 and 10 chair stands, and two summary tests of lower extremity performance. Sex-stratified generalized linear regression models were adjusted for age, race, BMI, appendicular lean mass, and whole body fat mass. RESULTS: In men, independent of either measure of peak torque and cofactors, RTD was a significant (P < 0.05) predictor of all lower extremity performance tests except the 400 m and 2.5 min walks. In women, independent of peak torque, RTD was only a significant independent correlate of the 6 m fast walk (P < 0.001). CONCLUSIONS: RTD independently contributes to physical functions in men but less in women. The mechanisms underlying the sex difference are unclear and require further study.

AB - The surface of an orthopaedic implant plays a crucial role in determining the adsorption of proteins and cell functions. A detailed comparative study has been made of the in vitro osteoblast responses to coarse-grained (grain size: 500 MUm), ultrafine-grained (grain size: 100 nm), coarse-porous (pore size: 350 nm), and fine-porous (pore size: 155 nm) surfaces of Ti-20Mo alloy. The purpose was to provide essential experimental data for future design of orthopaedic titanium implants for rapid osseointegration. Systematic original experimental data was produced for each type of surfaces in terms of surface wettability, cell morphology, adhesion, growth, and differentiation. Microscopic evidence was collected to reveal the detailed interplay between each characteristic surface with proteins or cells. Various new observations were discussed and compared with literature data. It was concluded that the coarse-porous surfaces offered the optimum topographical environment for osteoblasts and that the combination of ultrafine grains and considerable grain boundary areas is not an effective way to enhance cell growth and osteogenic capacity. Moreover, pore features (size and depth) have a greater effect than smooth surfaces on cell growth and osteogenic capacity. It proves that cells can discern the difference in pore size in the range of 100-350 nm. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 2020-2033, 2018.

PMID- 29569838 TI - The feasibility study of an in situ marine polysaccharide-based hydrogel as the vitreous substitute. AB - Although various biopolymers and synthetic compounds have been proposed and tested as the vitreous substitutes, no ideal material has been identified yet. In the present study, we developed an in situ-formed hydrogel by crosslinking hydroxypropyl chitosan with alginate dialdehyde. Physical properties of the hydrogel were studied and the cytotoxicity was evaluated using L929 fibroblasts, rabbit corneal endothelial cells and retinal pigment epithelial cells. In a preliminary in vivo study, the hydrogel was employed as vitreous substitute after vitrectomy surgery on rabbits and multiple parameters indicating biosafety and biocompatibility were measured and analyzed postoperatively. Our results showed that the refractive index, transmittance, pH value and density of the hydrogel were similar to those of human vitreous. Cytotoxicity tests demonstrated the hydrogel to be nontoxic to all of the three cell lines selected. Using the rabbit model, we showed that the hydrogel could form in situ and postoperative analysis of slit-lamp observation, intraocular pressure, corneal endothelium examination, B-scan ultrasound and fundus photography showed no significant adverse reactions in the operated eyes during the 90-day follow-up. However, electroretinogram and histopathological examinations indicated minor vision decline and decrease of the densities of cones and rods in the operated rabbit eyes. Collectively, our study suggested that the in situ-formed hydrogel could potentially be used as a vitreous substitute, with its long-term safety and efficacy to be further assessed.

PMID- 29569839 TI - Soy Phytoestrogens Do Not Fully Reverse Changes in Rat Pituitary Castration Cells: Unbiased Stereological Study. AB - The aim of the study was to examine the potential of the principal soy isoflavones, genistein and daidzein, or isoflavone rich soy extract to recover pituitary castration cells in orchidectomized adult male rats in comparison with the effects of estradiol. Two weeks post orchidectomy (Orx), animals received estradiol-dipropionate, genistein, daidzein or soy extract subcutaneously for 3 weeks. Control sham-operated (So) and Orx rats received just the vehicle. Changes in the volumes of pars distalis, of individual follicle-stimulating hormone (FSH) and luteinizing hormone (LH) containing cells, their volume, numerical density and number were determined by unbiased design-based stereology. The intracellular content of betaFSH and betaLH was estimated by relative intensity of fluorescence (RIF). Orchidectomy increased all examined stereological parameters and RIF. Compared to Orx, estradiol increased the volume of pars distalis, but reversed RIF and all morphometric parameters of gonadotropes to the level of So rats, except their number. Treatments with purified isoflavones and soy extract decreased RIF to the control So level, expressing an estradiol-like effect. However, the histological appearance and morphometrical features of gonadotropes did not follow this pattern. Genistein increased the volume of pars distalis, decreased the volume density of LH-labeled cells and raised the number of gonadotropes. Daidzein decreased the cell volume of gonadotropic cells but increased their number and numerical density. Soy extract induced an increase in number and numerical density of FSH-containing cells. Therefore, it can be concluded that soy phytoestrogens do not fully reverse the Orx-induced changes in pituitary castration cells. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND/AIMS: Published data on prevalence and severity of traumatic dental injuries (TDI) in Norway are limited. The aims of this study were to assess prevalence, distribution and severity of TDI in the permanent dentition of 16 year-old pupils in western Norway. MATERIAL AND METHODS: A retrospective longitudinal study, including historical clinical data, was conducted among 16 year-old high school pupils in the County of Hordaland, western Norway. First grade pupils attending high school, born in 1997, were invited to participate (n = 5184). Consent was given to access their dental records in the Public Dental Health Service in Hordaland, where information regarding TDI (diagnosis and treatment) and radiographs was interpreted. Only TDIs to anterior teeth were recorded (canine to canine in the maxilla and mandible) and classified using a modified version of the WHO's classification. RESULTS: A total of 2055 participants were included (response rate 40%). TDI prevalence was 16.4% (338 pupils), with the maxillary central incisors most affected (64.7%). A total of 637 teeth were involved. Boys were more prone to injury than girls (P < 0.05). Severity of TDI was divided into 3 groups (mild, moderate and severe), with the following distribution: 563 mild (88.4%), 39 moderate (6.1%) and 35 severe (5.5%). Peak age for TDI was 8-10 years (50.9%). CONCLUSIONS: Prevalence of TDI among Norwegian adolescents was moderate. Milder injuries were more frequent than moderate and severe injuries. Age and gender were risk factors with regard to TDI. Seasonal influence on the occurrence of TDI was not statistically significant.

PMID- 29569842 TI - Incidence and outcomes of out-of-hospital cardiac arrest: A New Zealand perspective. AB - OBJECTIVE: To describe the incidence and outcomes from out-of-hospital cardiac arrest (OHCA) in the New Zealand population served by the St John Ambulance Service. METHODS: A retrospective observational study was conducted using data from the St John New Zealand OHCA registry, which serves a population of around 4 million. The incidence and outcomes of adult patients who were treated for an OHCA between 1 October 2013 and 30 September 2015 are reported. RESULTS: A total of 7996 adult OHCA cases were attended, resuscitation was attempted in 3862 cases (60 per 100 000 person-years). The median response time was 9 min (interquartile range 7-12), the median age was 66 (interquartile range 53-77) and 69% were men. Most events occurred in the home (67%), bystanders witnessed 53%, EMS witnessed 16% and 31% were unwitnessed. Bystander CPR was administered in 62% of cases and 8% were defibrillated prior to EMS arrival. Most events had a presumed cardiac aetiology (77%) and 38% presented in a shockable rhythm. Of those who had attempted resuscitation, a return of spontaneous circulation sustained to hospital handover occurred in 30% of events and 15% survived to 30 days. Adjusted survival outcomes demonstrated differences according to ethnicity. CONCLUSION: This is the first study to describe the epidemiology and outcomes of OHCA in New Zealand. Our findings provide important baseline data to monitor temporal trends, investigate the impact of changes in the management of OHCA and demonstrate that there are opportunities for improvement across the system of care. PMID- 29569843 TI - Evaluation of the potential exposure of butterflies to genetically modified maize pollen in protected areas in Italy. AB - Environmental impacts of genetically modified crops are mandatorily assessed during their premarket phase. One of the areas of concern is the possible impact on nontarget organisms. Crops expressing Cry toxins might affect Lepidoptera larvae living outside cultivated fields, through pollen deposition on wild plants, which constitute their food source. While pollen toxicity varies among different events, possible exposure of nontarget species depends on the agro environmental conditions. This study was conducted in two protected areas in Italy, characterized by different climatic conditions, where many Lepidoptera species thrive in proximity to maize cultivations. To estimate the possible exposure in absence of the actual stressor (e.g., Cry1-expressing maize plants), we conducted a two-year field survey of butterflies and weeds. Indicator species were selected-Aglais (Inachis) io in the Northern site and Vanessa cardui in the Southern site-and their phenology was investigated. Pollen dispersal from maize fields was measured by collection in Petri dishes. Duration and frequency of exposure was defined by the overlap between pollen emission and presence of larvae on host plants. Different risk scenarios are expected in the two regions: highest exposure is foreseen for A. io in the Northern site, while minimal exposure is estimated for V. cardui in the Southern site. In the latter case, locally grown maize cultivars flower in mid-summer in coincidence with an aestivation period for several butterfly species due to hot and dry conditions. Moreover, host plants of V. cardui are at the end of their life cycle thus limiting food availability. PMID- 29569844 TI - Why do 'fast track' patients stay more than four hours in the emergency department? An investigation of factors that predict length of stay. AB - OBJECTIVE: Low-acuity 'fast track' patients represent a large portion of Australian EDs' workload and must be managed efficiently to meet the National Emergency Access Target. The current study determined the relative importance and estimated marginal effects of patient and system-related variables in predicting ED fast track patients who stayed longer than 4 h in the ED. METHODS: Data for ED presentations between 1 July 2014 and 30 June 2015 were collected from a large regional Australian public hospital. Only 'fast track' patients were included in the analysis. A gradient boosting machine was used to predict which patients would have an ED length of stay greater or less than 4 h. The performance of the final model was tested using a validation data set that was withheld from the initial analysis. A total of 27 variables were analysed. RESULTS: The model's performance was very good (area under receiver operating characteristic curve 0.89, where 1.0 is perfect prediction). The five most important variables for predicting length of stay were time-dependent and system-related (not patient related); these were the amount of time taken from when the patient arrived at the ED to: (i) order imaging; (ii) order pathology; (iii) request admission to hospital; (iv) allocate a clinician to care for the patient; and (v) handover a patient between ED clinicians. CONCLUSIONS: We identified the most important variables for predicting length of stay greater than 4 h for fast track patients in our ED. Identifying factors that influence length of stay is a necessary step towards understanding ED patient flow and identifying improvement opportunities. PMID- 29569845 TI - In this April issue.

AB - Although comprehensive guidelines for treatment of sepsis exist, current research continues to refine and revise several aspects of management. Imperatives for rapid administration of broad-spectrum antibiotics for all patients with sepsis may not be supported by contemporary data. Many patients may be better served by a more judicious approach allowing consideration of investigation results and evidence-based guidelines. Conventional fluid therapy has been challenged with early evidence supporting balanced, restricted fluid and early vasopressor use. Albumin, vasopressin and hydrocortisone have each been shown to support blood pressure and reduce catecholamine requirements but without effect on mortality, and as such should be considered for ED patients with septic shock on a case-by case basis. Measurement of quality care in sepsis should incorporate quality of blood cultures and guideline-appropriateness of antibiotics, as well as timeliness of therapy. Local audit is an essential and effective means to improve practice. Multicentre consolidation of data through agreed minimum sepsis data sets would provide baseline quality data, required for the design and evaluation of interventions.

AB - The performance of the CAM-B3LYP, omegaB97X and LC-BLYP long-range corrected density functional theory methods in the calculation of molecular first hyperpolarizabilities (beta) and low-lying charge transfer (CT) excitation energies of the metal alkynyl complexes M(C=C-4-C6 H4 -1-NO2 )(kappa2 -dppe)(eta5 -C5 H5 ) [M=Fe (1), Ru (2), Os (3)] and trans-[Ru{C=C-(1,4-C6 H4 C=C)n -4-C6 H4 1-NO2 }Cl(kappa2 -dppm)2 ] [n=0 (4), 1 (5), 2 (6)] was assessed. The BLYP, B3LYP and PBE0 standard exchange-correlation functionals and the Hartree-Fock method were also examined. The BLYP functional was shown to perform poorly in the calculation of beta and low-energy CT transitions. The hybrid functionals (B3LYP and PBE0) showed significant improvement over the pure functional BLYP, but overestimated the hyperpolarizability ratios and the wavelengths of the lowest energy metal-to-ligand CT transitions for 5 and 6. The effect of long-range corrections is noteworthy, particularly for the larger complexes, improving the calculation of beta ratios for 4-6. However, CAM-B3LYP, omegaB97X, and LC-BLYP considerably overestimated the low-lying CT energies. PBE0 was found to give the best transition energy match for 4. The influence of the phenylene ring orientation in the alkynyl ligand on the calculated properties is substantial, particularly for the larger complexes. For these types of calculations, a basis set with diffuse functions (at least 6-31+G(d)) for the heavy elements is recommended.

AB - The efficient generation of methane by total electroreduction of carbon monoxide (CO) could be of benefit for a more sustainable society. However, a highly efficient and selective catalyst for this process remains to be developed. In this study, density functional theory calculations indicate that steric hindrance in monolayer molybdenum sulfide with 2 S vacancies (DV-MoS2 ) can facilitate the conversion of CO into CH4 with high activity and selectivity under electrochemical reduction at a low potential of -0.53 V vs. RHE and ambient conditions. The potential is a significant improvement on the state-of-the-art Cu electrode (-0.74 V vs. RHE), with less electrical energy. Moreover, the results suggest that such steric hindrance effects are important for structure-sensitive catalytic reactions.

AB - Nonalcoholic fatty liver disease (NAFLD) is closely associated with obesity. Disulfide bond-forming oxidoreductase A-like protein (DsbA-L) is known to be a key molecule in protection against obesity and obesity-induced inflammation. In the present study, we used a modeling and simulation approach in an attempt to develop body mass index (BMI) and BMI-based NAFLD prediction models incorporating the DsbA-L polymorphism to predict the BMI and NAFLD in 341 elderly subjects. A nonlinear mixed-effect model best represented the sigmoidal relationship between the BMI and the logit function of the probability of NAFLD prevalence. The final models for BMI and NAFLD showed that DsbA-L rs1917760 polymorphism, age, and gender were associated with the BMI, whereas gender, patatin-like phospholipase 3 rs738409 polymorphism, HbA1c, and high-density and low-density lipoprotein cholesterol levels were associated with the risk of NAFLD. This information may aid in the genetic-based prevention of obesity and NAFLD in the general elderly population.

PMID- 29569853 TI - Revealing Factors Influencing the Fluorine-Centered Non-Covalent Interactions in Some Fluorine-Substituted Molecular Complexes: Insights from First-Principles Studies. AB - We examine the equilibrium structure and properties of six fully or partially fluorinated hydrocarbons and several of their binary complexes using computational methods. In the monomers, the electrostatic surface of the fluorine is predicted to be either entirely negative or weakly positive. However, its lateral sites are always negative. This enables the fluorine to display an anisotropic distribution of charge density on its electrostatic surface. While this is the electrostatic surface scenario of the fluorine atom, its negative sites in some of these monomers are shown to have the potential to engage in attractive engagements with the negative site(s) on the same atom in another molecule of the same type, or a molecule of a different type, to form bimolecular complexes. This is revealed by analyzing the results of current state-of-the-art computational approaches such as DFT, together with those obtained from the quantum theory of atoms in molecules, molecular electrostatic surface potential and symmetry adapted perturbation theories. We demonstrate that the intermolecular interaction energy arising in part from the universal London dispersion, which has been underappreciated for decades, is an essential factor in explaining the attraction between the negative sites, although energy arising from polarization strengthens the extent of the intermolecular interactions in these complexes. PMID- 29569854 TI - Interleukin-25 Axis Is Involved in the Pathogenesis of Human Primary and Experimental Murine Sjogren's Syndrome. AB - OBJECTIVE: To investigate the role of the interleukin-25 (IL-25)/IL-17 receptor B (IL-17RB) axis in experimental Sjogren's syndrome (SS) and in patients with primary SS and primary SS-associated lymphoma. METHODS: Expression of IL-25, IL 17RB, IL-17B, and tumor necrosis factor receptor-associated factor 6 (TRAF6) was analyzed on minor salivary gland (SG) samples from patients with primary SS and on parotid gland samples from patients with primary SS-associated B cell non Hodgkin's lymphoma (NHL). IL-17RB expression and the frequencies of natural group 2 innate lymphoid cells (ILC2s), inflammatory ILC2s, and M2-polarized macrophages were assessed by flow cytometry in SG mononuclear cells and peripheral blood mononuclear cells (PBMCs). Tissue distribution of ILC2s was studied by confocal microscopy. The role of recombinant IL-25 and of rituximab in modulating IL-25 expression was investigated in in vitro studies. IL-25/IL-17RB and TRAF6 expression and the role of IL-25 inhibition were also studied in the experimental murine model of SS. RESULTS: Activation of the IL-25/IL-17RB/TRAF6 axis correlated with the focus score and was observed in patients with primary SS and in patients with primary SS-associated NHL. A significant increase in the frequency of inflammatory ILC2s was observed both in SG mononuclear cells and in PBMCs. IL-25 stimulation of isolated SG mononuclear cells and PBMCs from patients and controls resulted both in inflammatory ILC2 expansion and in increased autoantibody production. Rituximab modulated expression of inflammatory ILC2s and IL-25 in primary SS. SG protein-immunized mice developed overt SS symptoms with increased IL-25 expression and increased frequency of CD4+IL-17RB+TRAF6+ cells. IL-25 neutralization attenuated disease progression and tissue pathology in mice with experimental SS. CONCLUSION: IL-25 may promote the inflammatory state in primary SS and may be a potential target for novel disease-modifying therapeutic strategies in patients with primary SS.

PMID- 29569857 TI - Correlation of High-Density Lipoprotein-Associated Paraoxonase 1 Activity With Systemic Inflammation, Disease Activity, and Cardiovascular Risk Factors in Psoriatic Disease. AB - OBJECTIVE: To compare the activity of high-density lipoprotein (HDL)-associated paraoxonase 1 (PON1) in patients with psoriasis (PsO) and patients with psoriatic arthritis (PsA), and to evaluate the association of PON1 activity with the extent of disease activity and severity of the cardiovascular disease (CVD) burden in these patients. METHODS: Serum levels of paraoxonase and arylesterase activity (both measures of PON1 function in humans) were measured in patients with PsA (n = 198, 51.0% male) and patients with PsO (n = 145, 50.3% male) who were enrolled in a longitudinal psoriatic disease biorepository. Data on PsA disease activity (using the Disease Activity Score in 28 joints [DAS28], Clinical Disease Activity Index, and painful/swollen joint counts), preexistent CVD and CVD risk factors (including diabetes, dyslipidemia, hypertension, and smoking), Framingham Risk Scores for CVD, quality of life measures, and laboratory test findings (erythrocyte sedimentation rate, C-reactive protein level, and lipid profiles) were recorded. RESULTS: Serum arylesterase activities were significantly lower in patients with PsO and patients with PsA (mean +/- SD 111.1 +/- 25.5 MUmoles/minute/ml and 124.4 +/- 33.4 MUmoles/minute/ml, respectively) compared to healthy controls (144.3 +/- 33.4 MUmoles/minute/ml) (each P < 0.001 versus healthy controls). Serum arylesterase activity decreased in parallel with increasing levels of disease activity (DAS28 scores, P = 0.012), older age (P = 0.013), higher body mass index (P = 0.042), greater incidence of metabolic syndrome (P = 0.004) and hypertension (P = 0.014), and worsening Framingham Risk Scores (P = 0.001). However, no correlation was seen between serum arylesterase activity and the extent of disease activity or CVD burden in patients with PsO. Serum paraoxonase activity trended lower both in patients with PsO and in patients with PsA (each P = 0.073 versus healthy controls). However, no association was seen between serum paraoxonase activity and the extent of disease activity or CVD burden in either of the patient cohorts. CONCLUSION: PON1 activity is decreased in psoriatic diseases. In the PsA cohort, decreases in arylesterase activity correlated with increasing severity of joint disease and CVD burden. Arylesterase activity, as compared to paraoxonase activity, appeared to serve as a more sensitive predictor of preexisting CV risk factors in the PsA cohort. However, this correlation was not observed in the PsO population. PMID- 29569859 TI - Exacerbation of Murine Experimental Autoimmune Myositis by Toll-Like Receptor 7/8. AB - OBJECTIVE: Toll-like receptor 7 (TLR-7), TLR-8, and interferon (IFN)-induced genes are expressed in patients with idiopathic inflammatory myositis. This study was undertaken to investigate whether their activation influences the natural history of the disease. METHODS: Experimental autoimmune myositis was induced in mice by injection of the amino-terminal portion of the murine histidyl-transfer RNA synthetase (HisRS). Disease was compared in the presence or the absence of the TLR-7/8 agonist R-848 in wild-type mice and in mice that fail to express the IFNalpha/beta receptor (IFNalpha/betaR-null mice). RESULTS: Experimental autoimmune myositis induced by a single intramuscular immunization with HisRS spontaneously abated after 7-8 weeks. In contrast, levels of anti-HisRS autoantibodies, endomysial/perimysial leukocyte infiltration, and myofiber regeneration persisted at the end of the follow-up period (22 weeks after immunization) in mice immunized with HisRS in the presence of R-848. Myofiber major histocompatibility complex (MHC) class I molecules were detectable only in mice immunized with both HisRS and R-848. MHC up-regulation occurred early and in muscles that were not directly injected with HisRS. Muscle MHC expression paralleled with leukocyte infiltration. MHC class I molecules were selectively up regulated in myotubes challenged with R-848 in vitro. Type I IFN was necessary for the prolonged autoantibody response and for the spreading of the autoimmune response, as demonstrated using IFNalpha/betaR-null mice. Muscle infiltration was maintained in the injected muscle up to the end of the follow-up period. CONCLUSION: TLR-7/8 activation is necessary to induce and maintain a systemic autoimmune response targeting the skeletal muscle. This experimental autoimmune myositis model reproduces many characteristics of human idiopathic inflammatory myopathies and may represent a tool for preclinical studies. PMID- 29569858 TI - An Autoimmune Basis for Raynaud's Phenomenon: Murine Model and Human Disease. AB - OBJECTIVE: Raynaud's phenomenon (RP) is common in anti-RNP-positive patients with rheumatic diseases but is not itself known to be caused by autoimmunity. The aim of this study was to assess autoantibodies that could mediate this process. METHODS: Antibodies derived from patient sera and from murine models of anti-RNP autoimmunity were screened for the ability to induce RP-like tissue ischemia and endothelial cell apoptosis in murine models and in vitro systems. RESULTS: RNP positive sera from RP patients and murine sera from RNP-positive B cell adoptive transfer recipients induced RP-like tissue ischemia and endothelial cell apoptosis. Proteomic analysis identified cytokeratin 10 (K10) as a candidate autoantigen in RP. Monoclonal anti-K10 antibodies reproduced patterns of ischemic tissue loss and endothelial cell apoptosis; K10 knockout or depletion of anti-K10 activity in serum was protective. Cold exposure enhanced K10 expression and in vivo tissue loss. CONCLUSION: Anti-K10 antibodies are sufficient to mediate RP like ischemia in murine models and are implicated in the pathogenesis of RP in patients with anti-RNP autoimmunity.

Nurses can reduce falls risk in older people by raising awareness of risk factors and embedding nutritional strategies in local falls reduction strategies. PMID- 29569860 TI - Maternal factors and preoperative nutrition in children with mild cases of congenital heart disease. AB - AIM: The preoperative poor nutrition of children with congenital heart disease (CHD) impacts the postoperative rehabilitation process of pediatric CHD cases. The factors of these children's preoperative poor nutrition, excluding the disease, have been underreported. The aim was to investigate the preoperative nutritional status of children with CHD who required a simple surgical repair and to analyze the maternal characteristics that are associated with poor nutrition in these sick children. METHODS: This was a cross-sectional survey. The weight and height of the children were measured, maternal data were collected via a questionnaire and a univariate analysis and multivariate logistic regression were used to analyze the association between maternal factors and the preoperative poor nutrition of the children with CHD. RESULTS: A total of 119 children with simple CHD were recruited to the study. The prevalence of poor nutrition was higher in the children with CHD ("cases") than in the healthy children ("controls"). An increased risk of poor nutrition was associated with lower mothers' perception, education level, understanding of the disease, and higher anxiety. CONCLUSIONS: Paying attention to maternal anxiety, depression, and knowledge and providing interventions for the mothers of children with CHD are important in order to promote the nutritional status of these children. PMID- 29569862 TI - Recognising and managing age-related dermatoporosis and skin tears. AB - Dermatoporosis is a chronic skin fragility syndrome, caused by age and environmental factors. People with dermatoporosis have skin whose protective mechanical function is reduced and which has a decreased tolerance for friction and shearing forces. Skin tears are another clinical consequence of age associated skin vulnerability and people with dermatoporosis are at increased risk of skin tears. Dermatoporosis may also delay the healing of skin tears, making it vital that healthcare professionals are aware of this condition. Skin tears have profound effects on the health and well-being of older people, and these kinds of injuries are being seen more frequently in clinical practice as the average age of the population increases. The treatment of skin tears in three older people with dermatoporosis is discussed and the clinical decisions made in each case. PMID- 29569863 TI - Infection prevention and control challenges of using a therapeutic robot. AB - This work was part of a National Institute for Health Research participatory action research and practice development study, which focused on the use of a therapeutic, robotic baby seal (PARO, for personal assistive robot) in everyday practice in a single-site dementia unit in Sussex. From the beginning of January 2017 until the end of September 2017, the cleaning and cleanliness of PARO was monitored through a service audit process that focused on the cleaning, amount of use and testing of contamination of PARO being used in everyday clinical practice with individuals and in group sessions. Its use and cleaning followed protocols developed by the study team, which incorporated hand hygiene and standard precaution policies. Its cleanliness was determined using an adenosine triphosphate (ATP) luminometer, with a benchmark of 50 relative light units (RLU). A reading of ATP below 50RLU is the level of cleanliness recommended for social areas in hospital settings. Throughout the study period, monitoring showed that all swab zones on PARO were within the benchmark of the 50RLU threshold for cleanliness. PARO has an emerging evidence base as a useful therapeutic device. However, introducing such devices into clinical practice may encounter barriers or concerns from an infection prevention and control (IPC) perspective. This study of PARO in clinical practice aims to address the IPC concerns raised and offers cleaning and testing protocols and results.

PMID- 29569866 TI - Single-nucleotide polymorphism (rs11204981) in filaggrin gene and its functional significance for asthma among children with eczema. AB - The aim of this study was to determine whether SNP in filaggrin gene and expression of filaggrin mRNAin buccal epithelium are associated with childhood eczema and with the phenotype of childhood eczemacombined with asthma. Genotyping for FLG (rs11204981) was performed in the following populations:patients with asthma (n = 99); ages 5-18 years (8 +/- 2.1), and control group (n = 98); ages 5 18 years(12 +/- 2.1) by using Real-time PCR. Level of mRNA expression was estimated by using reverse transcriptionand following real-time PCR. It was found out that 5.05 % of patients and 2.02 % of control group hadminor allele (AA; P>0.05), 27.27 % and 36.36 % of patients and control group, respectively, had heterozygousallele (GA; P>0.05) and 67.68 % and 61.62 % had major allele (GG) (P>0.05). Variants with theAA-genotype of the FLG rs11204981 were found to be 2.5 times more frequently among patients than incontrol group. We also found out that the level of mRNA FLG expression in GG-genotype is 22.8 +/- 11.67(P>0.05 compared to AA-genotype), 92.95 +/- 35.3 in GA genotype (P<0.05compared to GG-genotype) and21.8 +/- 13.4 in AA genotype (P>0.05 compared to GA-genotype). Thus, heterozygous variant has significantlyhigher expression of filaggrin in buccal epithelium. We suggest that SNP in FLG (rs11204981) may serveas an important predictive marker for the combined eczema plus asthma phenotype, and that the highestlevel of expression in heterozygous may have a protective role in developing allergy phenotype.Key words: snp; filaggrin; asthma; paediatrics. PMID- 29569867 TI - NITRIC OXIDE SYNTHASE ACTIVITY AND ITS CONCENTRATION IN THE TISSUES OF HUMAN THYROID CARCINOMAS. AB - The study of the activity of the constitutive form of nitricoxide synthase (cNOS) revealed that in the papillary thyroidcarcinomas it corresponded to that detected in unchangedextratumoral tissue, while the enzyme activity in follicularcarcinoma was half lesser. At the same time, the activity ofinducible nitric oxide synthase (iNOS) was higher in thepapillary and follicular carcinomas. Such changes in theenzyme activity were associated with an increase in its levelin papillary carcinomas, and with minor changes in follicularcarcinomas. In medullary carcinomas the parameters understudy corresponded to those in unchanged tissue, and in thepapillary carcinoma metastases without changes in enzymeactivity of nitric oxide formation, the level of the latter wasmuch higher. Elevated levels of nitric oxide and iNOS activityin papillary thyroid carcinomas did not depend significantlyon the aggression characteristics of the latter, being howeverabsent in tumors of T4 category on a background of reducedcNOS activity and less expressed in tumors surrounded by thetissue in the presence of a chronic thyroiditis. Furthermore,in the papillary carcinomas of papillary or follicular structurenitric oxide level did not differ from the normal range, beingslightly higher in tumors of solid or heterogeneous structurewith presence of solid areas, whereas in carcinomas ofpapillary-follicular structure it was twice, and in tissue of solidinsularstructure three times higher. iNOS hyperactivity wasobserved in the carcinomas of different structure, except fortumors of solid structure, in the tumor of which enzyme activitywas within the normal range, and in tumor of solid-insularstructure where it was significantly higher (as well as cNOSactivity) compared with tumors of other structure. Nitric oxidegenerating system is involved in the transformation of thyroidcells and progression of tumor growth, including throughapoptosis regulation, as shown by the results of an analysisof data obtained both in the present study and previously. Thenature of such involvement in papillary thyroid carcinomaswith different histological structure is different.Key words: nitric oxide; constitutive and inducible nitric oxidesynthase; thyroid carcinoma; apoptosis. PMID- 29569868 TI - What happens to an acellular dermal matrix after implantation in the human body? A histological and electron microscopic study. AB - Acellular matrices are used for various purposes and they have been studied extensively for their potential roles in regenerating tissues or organs. The acellular matrix generates physiological cues that mimic the native tissue microenvironment. Acellular dermal matrix (ADM) is a soft connective tissue graft generated by a decellularization process that preserves the intact extracellular skin matrix. Upon implantation, this structure serves as a scaffold for donor side cells to facilitate subsequent incorporation and revascularization. In breast reconstruction, ADM is used mainly for lower pole coverage and the shaping of a new breast. It helps control the positioning of the implant in the inframammary fold, and prevent the formation of contractile pseudocapsule around the breast implant. In this study, we provide a comprehensive histological description of ADM used for human breast reconstruction over the course of several months following implementation. Using immunohistochemical methods (a panel of 12 antibodies) coupled with optical and transmission electron microscopy, we confirmed that the original acellular dermal matrix became recolonized by fibroblasts and myofibroblasts, and also by various other free cells of the connective tissue (lymphocytes, macrophages and multinucleated giant cells, granulocytes, mast cells) after implantation into the patient's body. Within the implanted ADM, there was a relatively rapid ingrowth of blood vessels. Lymphatic vessels were only detected in one case 9 months after the implantation of the ADM. These results suggest that lymphangiogenesis is a longer process than angiogenesis. PMID- 29569869 TI - Leptin affects filopodia and cofilin in NK-92 cells in a dose- and time-dependent manner. AB - Hyperleptinemia, associated with obesity, is related with immune dysfunction and carcinogenesis. Natural Killer (NK) cells, a major component of the innate immune system are mediators of anti-tumor immunity and the most actively migrating cells among leukocytes. Actin rearrangement, promoted by cofilin plays a central role in cellular migration. Leptin affects the phosphorylation-dependent activity of cofilin and thus actin remodeling. We used human NK-92 cells to explore the in vitro effects of leptin on co-localization of cofilin and F-actin and on morphological changes in NK cells. NK-92 cells were incubated with different leptin concentrations (10 and 100 ng/mL) for 30 min and 24 h and immunocytochemically stained. Results demonstrate a dose- and time-dependent influence of leptin on cellular morphology. Utilizing confocal microscopy, we observed that the co-localization of cofilin-1 and F-actin was slightly influenced by leptin. In summary, the present study demonstrates an impact of a physiological leptin stimulation on the filopodia length, and a time-dependent effect on the co-localization of cofilin and F-actin in NK-92 cells. PMID- 29569870 TI - Novel insights into pericarp, protein body globoids of aleurone layer, starchy granules of three cereals gained using atomic force microscopy and environmental scanning electronic microscopy. AB - In this study, we applied Environmental Scanning Electron Microscopy-Energy Dispersive Spectroscopy (ESEM-EDS) and Atomic Force Microscopy (AFM) analysis to three different cereal caryopses: barley, oat and einkorn wheat. The morphological structures, chemical elemental composition and surface characteristics of the three cereals were described. Regarding the morphology, barley showed the thickest pericarp, providing a strong barrier digestion and absorption of nutrients. The aleurone layer of each cereal type contained protein body globoids within its cells. Large type-A and small type-B starchy granules were revealed in the endosperm of barley and einkorn wheat, whereas irregular starchy granules were found in oats. The starchy granule elemental composition, detected by ESEM-EDS, was rather homogenous in the three cereals, whereas the pericarp and protein body globoids showed heterogeneity. In the protein body globoids, oats showed higher P and K concentrations than barley and einkorn wheat. Regarding the topographic profiles, detected by AFM, einkorn wheat starchy granules showed a surface profile that differed significantly from that of oats and barley, which were quite similar to one another. The present work provides insights into the morphological and chemical makeup of the three grains shedding light on the higher bio-accessibility of einkorn wheat nutrients compared to barley and oats, providing important suggestions for human nutrition and technological standpoints. PMID- 29569871 TI - LOX-1 deficient mice show resistance to zymosan-induced arthritis. AB - Recent data suggest that the lectin-like oxidized low-density lipoprotein (ox LDL) receptor-1 (LOX-1)/ox-LDL system may be involved in the pathogenesis of arthritis. We aimed to demonstrate the roles of the LOX-1/ox-LDL system in arthritis development by using LOX-1 knockout (KO) mice. Arthritis was induced in the right knees of C57Bl/6 wild-type (WT) and LOX-1 KO mice via zymosan injection. Saline was injected in the left knees. Arthritis development was evaluated using inflammatory cell infiltration, synovial hyperplasia, and cartilage degeneration scores at 1, 3, and 7 days after administration. LOX-1, ox LDL, and matrix metalloproteinase-3 (MMP-3) expression in the synovial cells and chondrocytes was evaluated by immunohistochemistry. The LOX-1, ox-LDL, and MMP-3 expression levels in synovial cells were scored on a grading scale. The positive cell rate of LOX-1, ox-LDL, and MMP-3 in chondrocytes was measured. The correlation between the positive cell rate of LOX-1 or ox-LDL and the cartilage degeneration score was also examined. Inflammatory cell infiltration, synovial hyperplasia, and cartilage degeneration were significantly reduced in the LOX-1 KOmice with zymosan-induced arthritis (ZIA) compared to WT mice with ZIA. In the saline-injected knees, no apparent arthritic changes were observed. LOX-1 and ox LDL expression in synovial cells and chondrocytes were detected in the knees of WT mice with ZIA. No LOX-1 and ox-LDL expression was detected in the knees of LOX 1 KOmice with ZIA or the saline-injected knees of both mice. MMP-3 expression in the synovial cells and chondrocytes was also detected in knees of both mice with ZIA, and was significantly less in the LOX-1 KO mice than in WT mice. The positive cell rate of LOX-1 or ox-LDL and the cartilage degeneration score showed a positive correlation. Our data show the involvement of the LOX-1/ox-LDL system in murine ZIA development. LOX-1-positive synovial cells and chondrocytes are potential therapeutic targets for arthritis prevention. PMID- 29569872 TI - Concomitant use of heat-shock protein 70, glutamine synthetase and glypican-3 is useful in diagnosis of HBV-related hepatocellular carcinoma with higher specificity and sensitivity. AB - Hepatocellular carcinoma is the third leading cause of cancer-related death worldwide and late diagnosis is the main cause of death in HCC patients. In this study expression patterns of HSP70, GPC3 and GS and their relationships with pathogenesis of HCC in Iranian patients were investigated. The expression of HSP70, GPC3 and GS were determined by immunohistochemistry and quantitative real time PCR (q-PCR) methods, using 121 cases from patients with HBV alone, HCC without HBV, HBV+HCC and 30 normal tissues as control group. HSP70, GPC3 and GS were expressed in higher levels in HBV-related HCC samples compared to HBV alone group. The results showed that the labeling index of HSP70, GPC3 and GS are correlated with immunohistochemical and molecular expressions of HSP70, GPC3 and GS. The sensitivity and specificity for HCC diagnosis were 43.4% and 89.7% for HSP70, 64.3% and 90.4% for GPC3, and 60.7% and 94.3% for GS, respectively. The sensitivity and specificity of the panels with 3, 2 and 1 positive markers, regardless of which one, were 21.6% and 100%, 51.3% and 100% and 93.4% and 80.5% respectively. The current study demonstrated an association between HSP70, GPC3 and GS expressions and HBV-related HCC in our population. It was concluded that HSP70, GPC3 and GS expressions could be useful biomarkers for increasing the specificity and sensitivity of HCC diagnosis to acceptable level.

AB - Photobiomodulation (PBM) is a manipulation of cellular behavior using non ablative low intensity light sources. This manipulation triggers a cascade of metabolic effects and physiological changes resulting in improved tissue repair, of benefit in the treatment of tissue injury, degenerative or autoimmune diseases. PBM has witnessed an exponential increase in both clinical instrument technology and applications. It is therefore of benefit to find reliable experimental models to test the burgeoning laser technology for medical applications. In our work, we proposed the earthworm Dendrobaena veneta for the study of non-ablative laser-light effects on wound healing. In our preliminary work, D. veneta has been shown to be positively affected by PBM. New tests using D. veneta were set up to evaluate the effectiveness of a chosen 808 nm-64 J/cm2 1W-CW laser therapy using the AB2799 hand-piece with flat-top bean profile, on the wound healing process of the earthworm. Effective outcome was assimilated through examining the macroscopic, histological, and molecular changes on the irradiated posterior-segment of excised-earthworms with respect to controls. Three successive treatments, one every 24 hours, were concluded as sufficient to promote the wound healing, by effects on muscular and blood vessel contraction, decrement of bacteria load, reduction of inflammatory processes and tissue degeneration. D. veneta was demonstrated to be a reliable experimental organism that meets well the 3Rs principles and the National Science Foundation statement. Through their genetic and evolutionary peculiarity, comparable to those of scientifically accredited models, D. veneta allows the effect of laser therapies by multidisciplinary methods, at various degree of complexity and costs to be investigated.

AB - The histological characterization of the intestinal mucus layer is important for many scientific experiments investigating the interaction between intestinal microbiota, mucosal immune response and intestinal mucus production. The aim of this study was to examine and compare different fixation protocols for displaying and quantifying the intestinal mucus layer in piglets and to test which histomorphological parameters may correlate with the determined mucus layer thickness. Jejunal and colonal tissue samples of weaned piglets (n=10) were either frozen in liquid nitrogen or chemically fixed using methacarn solution. The frozen tissue samples were cryosectioned and subsequently postfixed using three different postfixatives: paraformaldehyde vapor, neutrally buffered formalin solution and ethanol solution. After dehydration, methacarn fixed tissues were embedded in paraffin wax. Both sections of cryopreserved and methacarn fixed tissue samples were stained with Alcian blue (AB)-PAS followed by the microscopically determination of the mucus layer thickness. Different pH values of the Alcian Blue staining solution and two mucus layer thickness measuring methods were compared. In addition, various histomorphological parameters of methacarn fixed tissue samples were evaluated including the number of goblet cells and the mucin staining area. Cryopreservation in combination with chemical postfixation led to mucus preservation in the colon of piglets allowing mucus thickness measurements. Mucus could be only partly preserved in cryosections of the jejunum impeding any quantitative description of the mucus layer thickness. The application of different postfixations, varying pH values of the AB solution and different mucus layer measuring methods led to comparable results regarding the mucus layer thickness. Methacarn fixation proved to be unsuitable for mucus depiction as only mucus patches were found in the jejunum or a detachment of the mucus layer from the epithelium was observed in the colon. Correlation analyses revealed that the proportion of the mucin staining area per crypt area (relative mucin staining) measured in methacarn fixed tissue samples corresponded to the colonal mucus layer thickness determined in cryopreserved tissue samples. In conclusion, the results showed that cryopreservation using liquid nitrogen followed by chemical postfixation and AB-PAS staining led to a reliable mucus preservation allowing a mucus thickness determination in the colon of pigs. Moreover, the detected relative mucin staining area may serve as a suitable histomorphological parameter for the assessment of the intestinal mucus layer thickness. The findings obtained in this study can be used for the implementation of an improved standard for the histological description of the mucus layer in the colon of pigs.

Merkel in 1875 and named "Tastzellen" (touch cells). Merkel cells are primarily localized in the basal layer of the epidermis and concentrated in touch-sensitive areas. In our previous work, we reported on the distribution of MCs in the human esophagus, so therefore we chose other parts of the human body to study them. We selected the human vagina, because it has a similar epithelium as the esophagus and plays very important roles in reproduction and sexual pleasure. Due to the fact that there are very few research studies focusing on the innervation of this region, we decided to investigate the occurrence of MCs in the anterior wall of the vagina. The aim of our research was to identify MCs in the stratified squamous non keratinized epithelium of the human vagina in 20 patients. For the identification of Merkel cells by light microscopy, we used antibodies against simple-epithelial cytokeratins (especially anti-cytokeratin 20). We also tried to identify them using transmission electron microscopy. Our investigation confirmed that 10 (50 %) of 20 patients had increased number of predominantly intraepithelial CK20 positive "Merkel-like" cells (MLCs) in the human vaginal epithelium. Subepithelial CK20 positive MLCs were observed in only one patient (5%). We tried to identify them also using transmission electron microscopy. Our investigation detected some unique cells that may be MCs. The purpose of vaginal innervation is still unclear. There are no data available concerning the distribution of MCs in the human vagina, so it would be interesting to study the role of MCs in the vaginal epithelium, in the context of innervation and epithelial biology.

AB - The reproductive tissues including the uterus undergo dramatic changes in seasonal breeders from the breeding to non-breeding seasons. Classically, sex steroid hormones play important roles in the uterine morphology and functions. To clarify the relationship between sex steroid hormones and seasonal changes in the uterine morphology and functions, the wild Daurian ground squirrels (Spermophilus dauricus) were used as seasonal breeder model. And the immunolocalizations and expression levels of androgen receptor (AR), estrogen receptors alpha and beta (ERalpha and ERbeta) and cytochrome P450 aromatase (P450arom) were investigated in the uteri of the wild Daurian ground squirrels in the breeding (April) and the non-breeding (June) seasons via immunohistochemistry, Western blot and RT-PCR. Histologically, the uterine weight, the thickness of endometrium and the glandular density were significantly higher in the uteri of the breeding season than those of the non-breeding season. In both seasons, the immunostaining of AR was only presented in stromal cells of the uteri; the positive staining of ERalpha and ERbeta were localized in stromal cells and glandular cells; P450arom was merely immunolocalized in glandular cells. The protein and mRNA expression levels of ERalpha, ERbeta and P450arom were higher in the uteri of the breeding season than those of the non-breeding season; conversely, the expressions of AR were higher in the uteri of the non-breeding season comparing with those of the breeding season in both protein and mRNA levels. The AR: ER ratio in the uteri of the non-breeding season exceeded the AR: ER ratio in the uteri of the breeding season in the wild Daurian ground squirrels. These results suggested that seasonal changes in the expression levels of AR, ERs and P450arom might be correlated with the uterine morphology and histology changes, and estrogen may play an important autocrine/paracrine role in regulating the uterine functions of the wild Daurian ground squirrels. PMID- 29569877 TI - Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n=26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy). AB - The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of meiosis. Thus the nuclear architecture characteristic of the karyotype of a species can be modified by chromosomal changes such as Rb chromosomes. In this study we analysed the meiotic prophase nuclear organization of the heterozygous spermatocytes from Mus musculus domesticus 2n=26, and the synaptic configuration of the hexavalent formed by the dependent Rb chromosomes Rbs 6.16, 16.10, 10.15, 15.17 and the telocentric chromosomes 6 and 17. Spreads of 88 pachytene spermatocytes from two males were studied and in all of them five metacentric bivalents, four telocentric bivalents, one hexavalent and the XY bivalent were observed. About 48% of the hexavalents formed a chain or a ring of synapsed chromosomes, the latter closed by synapsis between the short arms of telocentric chromosomes 6 and 17. About 52% of hexavalents formed an open chain of 10 synapsed chromosomal arms belonging to 6 chromosomes. In about half of the unsynapsed hexavalents one of the telocentric chromosome short arms appears associated with the X chromosome single axis, which was otherwise normally paired with the Y chromosome. The cluster of pericentromeric heterochromatin mostly determines the hexavalent's nuclear configuration, dragging the centromeric regions and all the chromosomes towards the nuclear envelope similar to an association of five telocentric bivalents. These reiterated encounters between these chromosomes restrict the interactions with other chromosomal domains and might favour eventual rearrangements within the metacentric, telocentric or hexavalent chromosome subsets. The unsynapsed short arms of telocentric chromosomes frequently bound to the single axis of the X chromosome could further complicate the already complex segregation of hexavalent chromosomes. PMID- 29569879 TI - The penetration of methanol into bovine cardiac and hepatic tissues is faster than ethanol and formalin. AB - Methanol, ethanol and formalin are commonly used as fixatives to preserve biological tissues from decay in the preparation of histological sections. Fixation of the inner layers of the tissue depends on the ability of the fixative to diffuse into the tissue. It is unknown whether methanol penetrates tissues at similar rates to other fixatives. This study aimed to compare the penetration rates of methanol, ethanol and formalin into bovine heart and liver tissues. The penetration distance and tissue shrinkage or expansion were measured by analysing the digital images of tissue before and after immersion in different fixatives for 1, 2, 6 or 10 h. Data were analysed using two-way ANOVA, followed by Bonferroni's post-hoc test. The penetration distance of methanol was significantly greater in both heart and liver tissues compared with that of ethanol (N=4, P<0.001). Methanol or ethanol immersion led to similar shrinkage of both tissues (P>0.05). The penetration rate of formalin was similar to that of ethanol in both tissues however it was significantly slower than methanol (N=4, P<0.005 in the heart; P<0.001 in the liver). The mean penetration coefficients of methanol, formalin and ethanol in the heart tissue were 2.609, 1.994 and 1.801, respectively, and 3.012, 2.153 and 2.113, respectively, in the liver tissue. The penetration coefficient of methanol was significantly greater than that of ethanol or formalin in both tissues (P<0.001 for each comparison). In conclusion, methanol penetrates tissue significantly faster than ethanol and formalin. PMID- 29569882 TI - HEART RATE REGULATION DURING ADAPTATION TO CONDITIONS IN ANTARCTICA. AB - The article deals with topical issues of the problem of studyingthe mechanisms of human adaptation to Antarctic conditions,in particular, the characteristics of the restructuring regulationof cardiovascular system during expedition activity atthe Ukrainian Antarctic Station "Academic Vernadsky". Thestudies were performed directly in Antarctica with the participationof winterers, who during a year were surveyed monthlyby cardiointervalography and ECG. As a result of analysis ofvariance of heart rate in Antarctic conditions we identified thephasic restructuring of the regulation of heart rhythm of winterers.The findings extend the understanding of the peculiaritiesof realization of regulating the circulatory system during thechange of adaptation phases. In particular, the RRNN indexhas a phasic structure and ranges +/- 7-9 c.u. from the beginningof wintering, and in the last phase is increased to -32 c.u. Theactivity of the development of stress condition among winterersreflects the dynamics of changes in the rate INt function,which from the beginning of wintering till January rangedfrom 2-5 c.u. by modulo, and in the months before the return(February, March), the rate reached 46 c.u. It is established adominant role of the time factor in influencing the quality adjustmentof adaptation processes. While during the first half ofthe expedition heart rate variability had a balanced regulatoryinfluence, at the end of the expedition an increased activityof the sympathetic division of the autonomic nervous systemand stress regulatory mechanisms were observed. This mayindicate for incomplete adaptation that requires the applicationof methods of correction of functional state. PMID- 29569878 TI - Energy Dispersive X-ray (EDX) microanalysis: A powerful tool in biomedical research and diagnosis. AB - The Energy Dispersive X-ray (EDX) microanalysis is a technique of elemental analysis associated to electron microscopy based on the generation of characteristic Xrays that reveals the presence of elements present in the specimens. The EDX microanalysis is used in different biomedical fields by many researchers and clinicians. Nevertheless, most of the scientific community is not fully aware of its possible applications. The spectrum of EDX microanalysis contains both semi-qualitative and semi-quantitative information. EDX technique is made useful in the study of drugs, such as in the study of drugs delivery in which the EDX is an important tool to detect nanoparticles (generally, used to improve the therapeutic performance of some chemotherapeutic agents). EDX is also used in the study of environmental pollution and in the characterization of mineral bioaccumulated in the tissues. In conclusion, the EDX can be considered as a useful tool in all works that require element determination, endogenous or exogenous, in the tissue, cell or any other sample.

AB - In acute experiments on rats with cannulated bile duct westudied the effect of Corvitin, water-soluble analogue ofquercetin, on secretion of bile. Intraportal administration ofthe test compound at doses of 2,5; 5 and 10 mg/kg resulted ina significant increase in the volume of secreted bile by 20,9,31,2 and 20,4%, respectively, as compared with the control. Using the method of thin layer chromatography it was establishedthe mild stimulating effect of Corvitin on the processesof bile acids conjugation with taurine and glycine, especiallywhen administered at a dose of 5 mg/kg. This flavonoid did notaffect the concentration of glycocholic acid, however increasedthe content of glycochenodeoxycholic and glycodeoxycholicacids in the mixture between 15 to 35,1%. Regarding free bileacids, the concentration of cholic acid, chenodeoxycholic anddeoxycholic acids in the mixture was increased significantlyrelative to control only after Corvitin application at dose 10 mg/kg. In the first case - from 17,9 to 29,8%, in the second - from25 to 65,4%. At the dose of 5 mg/kg, Corvitin significantlyincreased the ratio of bile cholates conjugation (maximum by23,2%), whereas 10 mg/kg of the drug decreased this indexby 27,0%. After administration of Corvitin, the hydroxylationratio in all experimental groups differed little from the control:at the dose of 5 and 10 mg/kg this parameter decreased by14%. Thus, Corvitin modulates exocrine function of the liver,causing an increase in bile secretion and concentration ofdifferent cholates, dose-dependently increasing or decreasingthe effectiveness of multienzyme systems providing processesof bile acids conjugation in rats.

AB - The effect of hypoxic preconditioning (HP) on the bloodoxygen-binding properties and liver oxidative damages wasdetermine during hepatic ischemia-reperfusion (HIR) in rabbits.Animals were randomized into two experimental groups:1st (HIR) - hepatic ischemia (30 min by Pringle maneuver) andreperfusion (120 min); 2nd (HP+HIR) - before HIR the rabbitswere passed through hypoxic chamber at 3500 m altitude during1 hr/day (3 times day after day). The parameters of bloodoxygen transport (r50, rSO2, rO2, rN, HCO3-, ABE and ect.),lipid peroxidation products (conjugated dienes, Schiff bases)and blood hepatic markers (ALT, AST) were detected. It'sfound that HIR leads to decline in hemoglobin oxygen affinity,activation of lipid peroxidation processes and elevation of ALTand AST activities in the 1st group. Hypoxic preconditioning(2nd group) markedly increased hemoglobin oxygen affinity,reduced the lipid peroxidation processes and ALT and ASTactivities in the blood during HIR. Thus, HP has a protectiveeffect during HIR through elevation of hemoglobin oxygenaffinity and declining hepatic oxidative damages.

AB - We studied the impact of pharmacological doses (5 mg / kg) ofmelatonin on the parameters of bone remodeling in 3 month-oldmale Wistar rats in autumn and spring. In autumn experiments,introduction of melatonin to young rats caused an increase ofalkaline phosphatase by 43,9% and hialuronidase activity by15,4% and decreased the content of glycosaminoglycans by46,7%. The concentration of total lipids and triglycerides wasdecreased. In spring, the introduction of melatonin to youngrats inhibited the physiological remodeling of bone tissue,reduced the activity of alkaline phosphatase and increasedthe activity of acid on the 78% and tartrate resistant acidphosphatases by 72% regardless of the oxygen consumptionlevel. The concentration of glycosaminoglycans and free aminoacids increased. Such changes may disturb the integrity of theorganic matrix and reduce the fixation of inorganic componentof connective tissue - hydroxyapatite crystals.

AB - The aim of our study was to investigate the role of intercellularmediators - interleukin-1 receptor antagonist (IL-1 RA),interleukin-17 (IL-17), receptor activator of nuclear factor kBligand (RANKL) and osteoprotegerin in the mechanisms ofmetabolic regulation of renal and bone tissue on model of violationsof bone remodeling in chronic kidney disease (CKD).It was found a significant increase in the content of cytokinesIL-1 RA (4,207 +/- 0,546 pg/ml), IL-17 (33,944 +/- 0,938 pg/ml), osteoprotegerin (28,338 +/- 1,223 pg/ml) and RANKL(0,184 +/- 0,018 pmol/l) in the serum of animals in violationof bone remodeling in CKD compared with the contents ofthe studied cytokines in animals in the control group (2,529+/- 0,132 pg/ml, 28,166 +/- 0,526 pg/ml, 21,588 +/- 0,763 pg/mland 0,131 +/- 0,006 pmol/l, respectively) (P<0.05). The obtainedcorrelations reflect the relationship between regulation of boneremodeling and the development of inflammation in CKD.The imbalance between pro- and anti-inflammatory cytokineplays an important role both in the development of CKD andin processes of bone remodeling.

AB - The aim of the work was to study the limbic-neocortical andmonoaminergic features of the development of withdrawalsyndrome of volatile organic compounds (VOC) inhalationsin rats. The study was carried out in 30 three months oldmale rats with dependence on inhalations of organic solvent"646" which contains up to 50 % mix of toluene and acetone.It has been shown that the withdrawal syndrome of inhalantis characterized by increased excitability and behavioralmanifestations of equivalents of convulsive reactions such asoral hyperkinesis, head shaking and changes in the frequencyamplitudespectrum of the biopotentials in structures of thebrain limbic-neocortical system with the initiation in the medialolfactory region and hippocampus. At the hypothalamus level,withdrawal of VOC inhalations produces the depleting impacton the catecholaminergic structures with a stronger effect inneuronal endings with adrenaline as neurotransmitter. Withdrawalsyndrome evokes a significant decrease in dopaminecontent by 61 %, noradrenaline by 77 % and adrenaline by 92% in the hypothalamus and increase in serotonin concentrationin blood serum by 16 % in rats with initial preference toinhalations of organic solvent "646".

PMID- 29569889 TI - Fitness and therapeutic potential of intermittent hypoxia training: a matter of dose. AB - The introduction of different methods of intermittent hypoxic training (IHT) into fitness, sports, militaryand medical practice has raised a lot of questions about the most beneficial regimens of such treatmentand their optimal instrumental implementation. Low doses of hypoxia might not be sufficient stimuli tomobilize adaptive mechanisms, while severe or prolonged hypoxia may provoke dangerous pathologicalprocesses. In this review, we pay attention to narrow practical question of the most effective and convenienttechnology of IHT implementation, notably the inhalation of hypoxic gas mixtures. Data strongly suggestthat in humans the training with 15-13% inhaled oxygen (FiO2) at various time characteristics does notprovide marked positive changes. Short-term daily sessions consisting 3-4 bouts of 5-7 min exposures to12-10% FiO2 alternating with equal durations of normoxia for 2-3 weeks have been shown as a mostbeneficial without maladaptive consequences for fitness and treatment of some diseases. More severe orlonger intermittent hypoxia protocols must be accompanied by strict monitoring of blood oxygen saturation(SpO2), electrocardiogram, breathing pattern and arterial blood pressure in order to avoid unexpectedundesirable individual reactions. For sports purposes, the reduction of oxygen content to individuallytolerable level for some minutes is justified as far as it maximizes benefits. However, such regimen requirespreliminary diagnostics of individual hypoxic tolerance and cardio-respiratory reactivity as well as rigorousmonitoring of vital functions during IHT and good feedback device. The use of oxygen concentrations below12% for treatment of diseases, especially in children and the elderly, are required substantial additionalresearch. Recently, a new mode of adaptive training was explored, which combines periods of hypoxia(12-10% FiO2) and hyperoxia (30-35% FiO2). Limited evidences suggest that such regime can reduce thetime of recovery periods, that is shorten the duration of sessions. However, there is still no strong comparativeevidence for humans that this method is much more efficient than hypoxic-normoxic mode. We appeal to allscientists working in the field of IHT not to hide their negative results but publish all observations in the openpress. It will make a significant contribution in developing of common guidelines for IHT implementationto improve public health of our Planet. PMID- 29569890 TI - Symmetric Sodium-Ion Capacitor Based on Na0.44MnO2 Nanorods for Low-Cost and High Performance Energy Storage. AB - Batteries and electrochemical capacitors play very important roles in the portable electronic devices and electric vehicles and have shown promising potential for large-scale energy storage applications. However, batteries or capacitors alone cannot meet the energy and power density requirements because rechargeable batteries have a poor power property, whereas supercapacitors offer limited capacity. Here, a novel symmetric sodium-ion capacitor (NIC) is developed based on low-cost Na0.44MnO2 nanorods. The Na0.44MnO2 with unique nanoarchitectures and iso-oriented feature offers shortened diffusion path lengths for both electronic and Na+ transport and reduces the stress associated with Na+ insertion and extraction. Benefiting from these merits, the symmetric device achieves a high power density of 2432.7 W kg-1, an improved energy density of 27.9 Wh kg-1, and a capacitance retention of 85.2% over 5000 cycles. Particularly, the symmetric NIC based on Na0.44MnO2 permits repeatedly reverse polarity characteristics, thus simplifying energy management system and greatly enhancing the safety under abuse condition. This cost-effective, high-safety, and high-performance symmetric NIC can balance the energy and power density between batteries and capacitors and serve as an electric power source for future low maintenance large-scale energy storage systems. PMID- 29569891 TI - High-Performance Supercapacitor of Graphene Quantum Dots with Uniform Sizes. AB - Graphene quantum dots (GQDs) with uniform sizes of less than 5 nm are synthesized by a novel top-down strategy. Nitric acid as a strong oxidant can be used to cut graphene oxide via sonication and hydrothermal processes. Moreover, purified GQDs are obtained from removing oxygen-containing functional groups in a heat treatment process. Both nanoscale size and edge effect of GQDs improve their abundant active sites and restrain the restack of graphene nanosheets. Meanwhile, their electrochemical performance demonstrates the properties of the GQDs for practical application in energy storage. The GQD electrode material shows an ideal electric double-layer capacitance behavior such as a high specific capacitance of 296.7 F g-1, a satisfactory energy density of 41.2 W h kg-1 at 1 A g-1, a low internal resistance, a small relaxation time, and an excellent cycling stability. The results illustrate excellent electrochemical activity, high conductivity, and enhanced ion transport rate on the surface of electrolyte and electrode. The advantages of GQDs confirm their unique characteristics for potential applications in the field of electrode materials for supercapacitors. PMID- 29569892 TI - In Situ Plating of Porous Mg Network Layer to Reinforce Anode Dendrite Suppression in Li-Metal Batteries. AB - Li dendrite suppression enables a highly reversible Li-metal battery. However the strategy to smooth Li surface, especially under long-term cycling and high current density, is still a big challenge. Here, we propose a facile additive strategy to reinforce Li dendrite inhibition in a range of ether and carbonate electrolytes. Dissoluble Mg(TFSI)2 is employed as a degradable electrolyte additive, leading to in situ plating of porous Mg network when contacting reductive Li atoms. Mg adatoms with extremely low diffusion energy barrier as lithiophilic sites enable a smooth or flaky morphology of Li surface even under a high current density of 2 mA/cm2 and high capacity of 6 mAh/cm2. Mg-salt additive significantly extends the cycling life of Li||Cu asymmetric cells up to 240 and 200 cycles for carbonate and ether electrolytes, respectively. Under a current density as high as 5 mA/cm2, the Li||Cu cell based on ether system can still survive up to 140 cycles with a small voltage hysteresis close to 60 mV. The hysteresis can be reduced to below 25 mV for lasting 200 cycles at 1 mA/cm2. This additive strategy provides a facile solution to in situ construction of conductive anode-electrolyte interface with low interface resistance for alleviating uneven Li nucleation. PMID- 29569893 TI - High-Throughput Generation of Durable Droplet Arrays for Single-Cell Encapsulation, Culture, and Monitoring. AB - High-throughput measurements can be achieved using droplet-based assays. In this study, we exploited the principles of wetting behavior and capillarity to guide liquids sliding along a solid surface with hybrid wettability. Oil-covered droplet arrays with uniformly sized and regularly shaped picoliter droplets were successfully generated on hydrophilic-in-hydrophobic patterned substrates. More than ten thousand 31-pL droplets were generated in 5 s without any sophisticated instruments. Covering the droplet arrays with oil during generation not only isolated the droplets from each other but also effectively prevented droplet evaporation. The oil-covered droplet arrays could be stored for more than 2 days with less than 35% volume loss. Single microspheres, microbial cells, or mammalian cells were successfully captured in the droplets. We demonstrate that Escherichia coli could be encapsulated at a certain number (1-4) and cultured for 3 days in droplets. Cell population and morphology were dynamically tracked within individual droplets. Our droplet array generation method enables high throughput processing and is facile, efficient, and low-cost; in addition, the prepared droplet arrays have enormous potential for applications in chemical and biological assays. PMID- 29569894 TI - Lateral Heterostructures Formed by Thermally Converting n-Type SnSe2 to p-Type SnSe. AB - Different two-dimensional (2D) materials, when combined together to form heterostructures, can exhibit exciting properties that do not exist in individual components. Therefore, intensive research efforts have been devoted to their fabrication and characterization. Previously, vertical and in-plane 2D heterostructures have been formed by mechanical stacking and chemical vapor deposition. Here, we report a new material system that can form in-plane p-n junctions by thermal conversion of n-type SnSe2 to p-type SnSe. Through scanning tunneling microscopy and density functional theory studies, we find that these two distinctively different lattices can form atomically sharp interfaces and have a type II to nearly type III band alignment. We also demonstrate that this method can be used to create micron-sized in-plane p-n junctions at predefined locations. These findings pave the way for further exploration of the intriguing properties of the SnSe2-SnSe heterostructure. PMID- 29569895 TI - On the Correlation between the Microscopic Structure and Properties of Phosphate Cross-Linked Chitosan Gels. AB - Ionic chitosan gels fabricated using multivalent anions, tripolyphosphate (TPP) or pyrophosphate (PPi), respectively, have been investigated as potential biomaterials to be used in tissue engineering. Starting from the hypothesis that the polymer mesh texture at the microscale affects the final performance of the resulting materials, an innovative image analysis approach is presented in the first part of the article, which is aimed at deriving quantitative information from transmission electron microscopy images. The image analysis of the (more extended) central area of the gel networks revealed differences between both the cross-linking densities and pore size distributions of the two systems, the TPP gels showing a higher connectivity. Chitosan-TPP gels showed a limited degradation in simulated physiological media up to 6 weeks, reasonably ascribed to the texture of the (more extended) central area of the gels, whereas PPi counterparts degraded almost immediately. The release profiles and the calculation of diffusion coefficients for bovine serum albumin and cytochrome c, herein used as model payloads, indicated a different release behavior depending on the polymer network homogeneity/inhomogeneity and molecular weight of loaded molecules. This finding was ascribed to the marked inhomogeneity of the PPi gels (at variance with the TPP ones), which had been demonstrated in our previous work. Finally, thorough in vitro studies demonstrated good biocompatibility of both chitosan gels, and because of this feature, they can be used as suitable scaffolds for cellular colonization and metabolic activity. PMID- 29569896 TI - Electrolytic CO2 Reduction in a Flow Cell. AB - Electrocatalytic CO2 conversion at near ambient temperatures and pressures offers a potential means of converting waste greenhouse gases into fuels or commodity chemicals (e.g., CO, formic acid, methanol, ethylene, alkanes, and alcohols). This process is particularly compelling when driven by excess renewable electricity because the consequent production of solar fuels would lead to a closing of the carbon cycle. However, such a technology is not currently commercially available. While CO2 electrolysis in H-cells is widely used for screening electrocatalysts, these experiments generally do not effectively report on how CO2 electrocatalysts behave in flow reactors that are more relevant to a scalable CO2 electrolyzer system. Flow reactors also offer more control over reagent delivery, which includes enabling the use of a gaseous CO2 feed to the cathode of the cell. This setup provides a platform for generating much higher current densities ( J) by reducing the mass transport issues inherent to the H cells. In this Account, we examine some of the systems-level strategies that have been applied in an effort to tailor flow reactor components to improve electrocatalytic reduction. Flow reactors that have been utilized in CO2 electrolysis schemes can be categorized into two primary architectures: Membrane based flow cells and microfluidic reactors. Each invoke different dynamic mechanisms for the delivery of gaseous CO2 to electrocatalytic sites, and both have been demonstrated to achieve high current densities ( J > 200 mA cm-2) for CO2 reduction. One strategy common to both reactor architectures for improving J is the delivery of CO2 to the cathode in the gas phase rather than dissolved in a liquid electrolyte. This physical facet also presents a number of challenges that go beyond the nature of the electrocatalyst, and we scrutinize how the judicious selection and modification of certain components in microfluidic and/or membrane based reactors can have a profound effect on electrocatalytic performance. In membrane-based flow cells, for example, the choice of either a cation exchange membrane (CEM), anion exchange membrane (AEM), or a bipolar membrane (BPM) affects the kinetics of ion transport pathways and the range of applicable electrolyte conditions. In microfluidic cells, extensive studies have been performed upon the properties of porous carbon gas diffusion layers, materials that are equally relevant to membrane reactors. A theme that is pervasive throughout our analyses is the challenges associated with precise and controlled water management in gas phase CO2 electrolyzers, and we highlight studies that demonstrate the importance of maintaining adequate flow cell hydration to achieve sustained electrolysis.

AB - The increasing demands for display devices with low power consumption and outdoor readability have stimulated comprehensive research into full-color reflective displays that employ color-tunable photonic crystal technologies. Although the recently developed crystalline colloidal arrays (CCAs) of the charged microspheres have shown the outstanding color tunability, the practical application is limited because the use of highly polar liquid medium such as water is required to maintain the charges on the surface of microsphere, whereas it is not suitable for long-term use in an electric field. Herein, a self assembled CCA from charged poly( t-butyl methacrylate) microspheres was successfully fabricated, which was stabilized by the charged inverse micelles of sodium di-2-ethylhexyl-sulfosuccinate in a nonpolar isoparaffinic fluid. A charged all-organic CCA was found to exhibit full-color tunability with a 1000 fold reduction in the power consumption (~6 MUW cm-2) under a direct current voltage bias of 4 V in comparison to that in an aqueous system, which is a promising feature for a low-power-consumption display device.

AB - Biomimetic microarchitectured polymer layers, such as inverted hemispherical architectured (IHSA)-polydimethylsiloxane (PDMS) and hemispherical architectured (HSA)-PDMS layers, were prepared by a simple and cost-effective soft-imprinting lithography method via a hexagonal close-packed polystyrene microsphere array/silicon mold. The IHSA-PDMS/glass possessed superior antireflection (AR) characteristics with the highest/lowest average transmittance/reflectance ( Tavg/ Ravg) values of approximately 89.2%/6.4% compared to the HSA-PDMS/glass, flat PDMS/glass, and bare glass ( Tavg/ Ravg ~88.8%/7.5%, 87.5%/7.9%, and 87.3%/8.8%, respectively). In addition, the IHSA-PDMS/glass also exhibited a relatively strong light-scattering property with the higher average haze ratio ( Havg) of ~38% than those of the bare glass, flat-PDMS/glass, and HSA-PDMS/glass (i.e., Havg ~ 1.1, 1.7, and 34.2%, respectively). At last, to demonstrate the practical feasibility under light control of the solar cells, the IHSA-PDMS was laminated onto the glass substrates of perovskite solar cells (PSCs) as an AR layer, and their device performances were explored. Consequently, the short-circuit current density of the PSCs integrated with the IHSA-PDMS AR layer was improved by ~17% when compared with the device without AR layer, resulting in the power conversion efficiency (PCE) up to 19%. Therefore, the IHSA-PDMS is expected to be applied as an AR layer for solar cells to enhance their light absorption as well as the PCE.

AB - Nanogaps as "hot spots" with highly localized surface plasmon can generate ultrastrong electromagnetic fields. Superior to the exterior nanogaps obtained via aggregation and self-assembly, interior nanogaps within Au and Ag nanostructures give stable and reproducible surface-enhanced Raman scattering (SERS) signals. However, the synthesis of nanostructures with interior hot spots is still challenging because of the lack of high-yield strategies and clear design principles. Herein, gold-silver nanoclusters (Au-Ag NCs) with multiple interior hot spots were fabricated as SERS platforms via selective growth of Ag nanoparticles on the tips of Au nanostars (Au NSs). Furthermore, the interior gap sizes of Au-Ag NCs can be facilely tuned by changing the amount of AgNO3 used. Upon 785 nm excitation, single Au-Ag NC350 exhibits 43-fold larger SERS enhancement factor and the optimal signal reproducibility relative to single Au NS. The SERS enhancement factors and signal reproducibility of Au-Ag NCs increase with the decrease of gap sizes. Collectively, the Au-Ag NCs could serve as a flexible, reproducible, and active platform for SERS investigation. PMID- 29569901 TI - Bioderived Three-Dimensional Hierarchical Nanostructures as Efficient Surface Enhanced Raman Scattering Substrates for Cell Membrane Probing. AB - In this work, we propose the use of complex, bioderived nanostructures as efficient surface-enhanced Raman scattering (SERS) substrates for chemical analysis of cellular membranes. These structures were directly obtained from a suitable gold metalization of the Pseudonitzchia multistriata diatom silica shell (the so called frustule), whose grating-like geometry provides large light coupling with external radiation, whereas its extruded, subwavelength lateral edge provides an excellent interaction with cells without steric hindrance. We carried out numerical simulations and experimental characterizations of the supported plasmonic resonances and optical near-field amplification. We thoroughly evaluated the SERS substrate enhancement factor as a function of the metalization parameters and finally applied the nanostrucures for discriminating cell membrane Raman signals. In particular, we considered two cases where the membrane composition plays a fundamental role in the assessment of several pathologies, that is, red blood cells and B-leukemia REH cells.

AB - Selective determination of aquatic chromium is critically important because of the dramatic differences in health and environment impacts by trivalent and hexavalent forms of chromium; however, it is challenging. In this work, for the first time, a nonconjugated polymer fluorophore (GCPF) was synthesized by cross linking chitosan with glutaraldehyde via Schiff base reactions and systematically investigated for selective determination of Cr(VI). The results revealed that the synthesized GCPF exhibited excellent photostability and water solubility. More importantly, GCPF possessed dramatically enhanced fluorescence intensity originated from the n-pi* transitions of the Schiff base subfluorophore groups (e.g., C?N) that can be selectively and sensitively quenched by Cr(VI) through oxidative damages to C?N group. An effective EDTA masking agent approach was employed to minimize ionic interferences. In the presence of high concentration of interference ions including Cr(III), the quenching GCPF fluorescence is capable of selectively determining Cr(VI) within a concentration range up to 50 MUM and a detection limit of 0.22 MUM. The analytical performance of GCPF was also confirmed by analyzing real surface water and industrial samples.

AB - Owing to high specific capacity of ~250 mA h g-1, lithium-rich layered oxide cathode materials (Li1+ xNi yCo zMn(3- x-2 y-3 z)/4O2) have been considered as one of the most promising candidates for the next-generation cathode materials of lithium ion batteries. However, the commercialization of this kind of cathode materials seriously restricted by voltage decay upon cycling though Li-rich materials with high cobalt content have been widely studied and show good capacity. This research successfully suppresses voltage decay upon cycling while maintaining high specific capacity with low Co/Ni ratio in Li-rich cathode materials. Online continuous flow differential electrochemical mass spectrometry (OEMS) and in situ X-ray diffraction (XRD) techniques have been applied to investigate the structure transformation of Li-rich layered oxide materials during charge-discharge process. The results of OEMS revealed that low Co/Ni ratio lithium-rich layered oxide cathode materials released no lattice oxygen at the first charge process, which will lead to the suppression of the voltage decay upon cycling. The in situ XRD results displayed the structure transition of lithium-rich layered oxide cathode materials during the charge-discharge process. The Li1.13Ni0.275Mn0.580O2 cathode material exhibited a high initial medium discharge voltage of 3.710 and a 3.586 V medium discharge voltage with the lower voltage decay of 0.124 V after 100 cycles. PMID- 29569903 TI - Highly Sensitive and Automated Surface Enhanced Raman Scattering-based Immunoassay for H5N1 Detection with Digital Microfluidics. AB - Digital microfluidics (DMF) is a powerful platform for a broad range of applications, especially immunoassays having multiple steps, due to the advantages of low reagent consumption and high automatization. Surface enhanced Raman scattering (SERS) has been proven as an attractive method for highly sensitive and multiplex detection, because of its remarkable signal amplification and excellent spatial resolution. Here we propose a SERS-based immunoassay with DMF for rapid, automated, and sensitive detection of disease biomarkers. SERS tags labeled with Raman reporter 4-mercaptobenzoic acid (4-MBA) were synthesized with a core@shell nanostructure and showed strong signals, good uniformity, and high stability. A sandwich immunoassay was designed, in which magnetic beads coated with antibodies were used as solid support to capture antigens from samples to form a beads-antibody-antigen immunocomplex. By labeling the immunocomplex with a detection antibody-functionalized SERS tag, antigen can be sensitively detected through the strong SERS signal. The automation capability of DMF can greatly simplify the assay procedure while reducing the risk of exposure to hazardous samples. Quantitative detection of avian influenza virus H5N1 in buffer and human serum was implemented to demonstrate the utility of the DMF-SERS method. The DMF-SERS method shows excellent sensitivity (LOD of 74 pg/mL) and selectivity for H5N1 detection with less assay time (<1 h) and lower reagent consumption (~30 MUL) compared to the standard ELISA method. Therefore, this DMF SERS method holds great potentials for automated and sensitive detection of a variety of infectious diseases. PMID- 29569904 TI - Purification of Semiconducting Polymer Dots by Size Exclusion Chromatography Prior to Cytotoxicity Assay and Stem Cell Labeling. AB - Semiconducting polymer dots (Pdots) as fluorescent probes have shown promising applications because of their excellent optical properties. However, apparent differences were observed in cytotoxicity assays, which might originate from impurities introduced in polymer synthesis or nanoparticle preparation. A simple gel-filtration-based purification method was used to address this issue. Purified Pdots displayed obviously decreased cytotoxicity as compared with the same batch of unpurified Pdots. The purified Pdots were further examined in a cytotoxicity study on mesenchymal stem cells (MSCs), which are very sensitive to exogenous probes. The results indicated that purified Pdots did not affect the proliferation ability of MSCs, while unpurified Pdots could have obvious cytotoxicity. In addition, the purified Pdots did not show cytotoxicity even after 6 months of storage. Our results demonstrated that gel filtration is an effective method for obtaining Pdots with minimal cytotoxicity, which are more suitable for biological applications.

AB - Separations of f-block elements are a critical aspect of nuclear waste processing. Redox-based separations offer promise, but challenges remain in stabilizing and differentiating actinides in high oxidation states. The investigation of new ligand types that provide thermodynamic stabilization to high-valent actinides is essential for expanding their fundamental chemistry and to elaborate new separation techniques and storage methods. We report herein the preparation and characterization of Th and U complexes of the pyridyl hydroxylamine ligand, N- tert-butyl- N-(pyridin-2-yl)hydroxylamine (pyNO-). Electrochemical studies performed on the homoleptic complexes [M(pyNO)4] (M = Th, U) revealed significant stabilization of the U complex upon one-electron oxidation. The salt [U(pyNO)4]+ was isolated by chemical oxidation of [U(pyNO)4]; spectroscopic and computational data support assignment as a UV cation. PMID- 29569905 TI - Novel Antihypertensive Prodrug from Grape Seed Proanthocyanidin Extract via Acid Mediated Depolymerization in the Presence of Captopril: Synthesis, Process Optimization, and Metabolism in Rats. AB - Grape seed extract contains a high content of proanthocyanidins that can be depolymerized into C-4-substituted (epi)catechin derivatives in the presence of nucleophiles. However, the biological and medicinal values of depolymerization products have been rarely investigated. Recently, we developed a novel depolymerization product (-)-epicatechin-4beta- S-captopril methyl ester (ECC) derived from the reaction of grape seed proanthocyanidin extract with captopril in the presence of acidified methanol. A central composite design was employed to select the most appropriate depolymerization temperature and time to obtain the target product ECC with a high yield. A total of 16 metabolites of ECC in rat urine, feces, and plasma were identified using liquid chromatography quadrupole time-of-flight tandem mass spectrometry. The in vivo results suggested that ECC could release captopril methyl ester and epicatechin, followed by the generation of further metabolites captopril and epicatechin sulfate conjugates. Therefore, ECC may be used as a potential prodrug with synergistic or additive hypotensive effects. PMID- 29569907 TI - Design and Mechanism of GABA Aminotransferase Inactivators. Treatments for Epilepsies and Addictions. AB - When the brain concentration of the inhibitory neurotransmitter gamma aminobutyric acid (GABA) diminishes below a threshold level, the excess neuronal excitation can lead to convulsions. This imbalance in neurotransmission can be corrected by inhibition of the enzyme gamma-aminobutyric acid aminotransferase (GABA-AT), which catalyzes the conversion of GABA to the excitatory neurotransmitter l-glutamic acid. It also has been found that raising GABA levels can antagonize the rapid elevation and release of dopamine in the nucleus accumbens, which is responsible for the reward response in addiction. Therefore, the design of new inhibitors of GABA-AT, which increases brain GABA levels, is an important approach to new treatments for epilepsy and addiction. This review summarizes findings over the last 40 or so years of mechanism-based inactivators (unreactive compounds that require the target enzyme to catalyze their conversion to the inactivating species, which inactivate the enzyme prior to their release) of GABA-AT with emphasis on their catalytic mechanisms of inactivation, presented according to organic chemical mechanism, with minimal pharmacology, except where important for activity in epilepsy and addiction. Patents, abstracts, and conference proceedings are not covered in this review. The inactivation mechanisms described here can be applied to the inactivations of a wide variety of unrelated enzymes.

AB - Americium 241 is a potential alternative to plutonium 238 as an energy source for missions into deep space or to the dark side of planetary bodies. In order to use the 241Am isotope for radioisotope thermoelectric generator or radioisotope heating unit (RHU) production, americium materials need to be developed. This study focuses on the stabilization of a cubic americium oxide phase using uranium as the dopant. After optimization of the material preparation, (Am0.80U0.12Np0.06Pu0.02)O1.8 has been successfully synthesized to prepare a 2.96 g pellet containing 2.13 g of 241Am for fabrication of a small scale RHU prototype. Compared to the use of pure americium oxide, the use of uranium-doped americium oxide leads to a number of improvements from a material properties and safety point of view, such as good behavior under sintering conditions or under alpha self-irradiation. The mixed oxide is a good host for neptunium (i.e., the 241Am daughter element), and it has improved safety against radioactive material dispersion in the case of accidental conditions. PMID- 29569909 TI - Thiol Reactivity of Curcumin and Its Oxidation Products. AB - The polypharmacological effects of the turmeric compound curcumin may be partly mediated by covalent adduction to cellular protein. Covalent binding to small molecule and protein thiols is thought to occur through a Michael-type addition at the enone moiety of the heptadienedione chain connecting the two methoxyphenol rings of curcumin. Here we show that curcumin forms the predicted thiol-Michael adducts with three model thiols, glutathione, N-acetylcysteine, and beta mercaptoethanol. More abundant, however, are respective thiol adducts of the dioxygenated spiroepoxide intermediate of curcumin autoxidation. Two electrophilic sites at the quinone-like ring of the spiroepoxide are identified. Addition of beta-mercaptoethanol at the 5'-position of the ring gives a 1,7 dihydroxycyclopentadione-5' thioether, and addition at the 1'-position results in cleavage of the aromatic ring from the molecule, forming methoxyphenol-thioether and a tentatively identified cyclopentadione aldehyde. The curcuminoids demethoxy and bisdemethoxycurcumin do not form all of the possible thioether adducts, corresponding with their increased stability toward autoxidation. RAW264.7 macrophage-like cells activated with phorbol ester form curcumin-glutathionyl and the 1,7-dihydroxycyclopentadione-5'-glutathionyl adducts. These studies indicate that the enone of the parent compound is not the only functional electrophile in curcumin, and that its oxidation products provide additional electrophilic sites. This suggests that protein binding by curcumin may involve oxidative activation into reactive quinone methide and spiroepoxide electrophiles. PMID- 29569910 TI - Rational Design of Dimeric Lysine N-Alkylamides as Potent and Broad-Spectrum Antibacterial Agents. AB - Antibiotic resistance is one of the biggest threats to public health, and new antibacterial agents hence are in an urgent need to combat infectious diseases caused by multidrug-resistant (MDR) pathogens. Utilizing dimerization strategy, we rationally designed and efficiently synthesized a new series of small molecule dimeric lysine alkylamides as mimics of AMPs. Evaluation of these mimics against a panel of Gram-positive and Gram-negative bacteria including MDR strains was performed, and a broad-spectrum and potent compound 3d was identified. This compound displayed high specificity toward bacteria over mammalian cell. Time kill kinetics and mechanistic studies suggest that compound 3d quickly eliminated bacteria in a bactericidal mode by disrupting bacterial cell membrane. In addition, lead compound 3d could inhibit biofilm formation and did not develop drug resistance in S. aureus and E. coli over 14 passages. These results suggested that dimeric lysine nonylamide has immense potential as a new type of novel small molecular agent to combat antibiotic resistance. PMID- 29569911 TI - Role of Glucuronidation and P450 Oxidation in the Bioactivation of Bromfenac. AB - Bromfenac is a nonsteroidal anti-inflammatory drug that was approved in the United States in 1997. It was withdrawn from clinical use less than one year later, in 1998, due to hepatotoxicity. We investigate the potential of bromfenac to be metabolized to reactive intermediates to further the current understanding of bromfenac bioactivation. Incubations were conducted with hepatocytes and human, rat, and cynomolgus liver microsomes fortified with cofactors and N acetylcysteine. One thioether adduct of hydroxylated bromfenac and three thioether adducts of hydroxylated bromfenac indolinone were detected in extracts following incubations in liver microsomes fortified with NADPH and UDPGA. These findings demonstrate a bioactivation pathway for bromfenac and contribute to the body of evidence that could advance the understanding of the toxicity associated with bromfenac. PMID- 29569912 TI - Free Radical Production and Oxidative Stress in Lung Tissue of Patients Exposed to Sulfur Mustard: An Overview of Cellular and Molecular Mechanisms. AB - Sulfur mustard (SM) is a chemical alkylating compound that primary targets lung tissue. It causes a wide variety of pathological effects in respiratory system such as chronic bronchitis, bronchiolitis obliterans, necrosis of the mucosa and inflammation, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis. However, molecular and cellular mechanisms for these pathologies are still unclear. Oxidative stress (OS) induced by reactive oxygen species (ROS) is likely a significant mechanism by which SM leads to cell death and tissues injury. SM can trigger various molecular and cellular pathways that are linked to ROS generation, OS, and inflammation. Hypoxia-induced oxidative stress, reduced activity of enzymatic antioxidants, depletion of intercellular glutathione (GSH), decreased productivity of GSH-dependent antioxidants, mitochondrial dysfunction, accumulation of leukocytes and proinflammatory cytokines, and increased expression of ROS producing-related enzymes and inflammatory mediators are the major events in which SM leads to massive production of ROS and OS in pulmonary system. Therefore, understanding of these molecules and signaling pathways gives us valuable information about toxicological effects of SM on injured tissues and the way for developing a suitable clinical treatment. In this review, we aim to discuss the possible mechanisms by which SM induces excessive production of ROS, OS, and antioxidants depletion in lung tissue of exposed patients. PMID- 29569913 TI - Development of Polyclonal Antibodies for Detection of Diosbulbin B-Derived cis Enedial Protein Adducts. AB - Diosbulbin B (DSB), a major component of herbal medicine Dioscorea bulbifera L. (DB), can be metabolized to an electrophilic intermediate, DSB-derived cis enedial (DDE). DDE was suggested to contribute to the hepatotoxicity observed in experimental animals and humans after their exposure to DSB. Our previous work found that DDE reacted with primary amino and/or sulfhydryl groups of hepatic protein. The objective of the study was to develop polyclonal antibodies that can recognize DDE-derived protein adducts. Immunogens synthesized from DDE and keyhole limpet hemocyanin were employed to raise polyclonal antibodies in rabbits. An enzyme-linked immunosorbent assay (ELISA) demonstrated high titers of antisera obtained from immunized rabbits. Immunoblot analysis showed that DDE modified bovine serum albumin (BSA) was recognized by the obtained polyclonal antibodies in a concentration-dependent manner and without cross-reaction to native BSA. Competitive ELISA and competitive immunoblot analyses defined the specificity of the antibodies to recognize BSA modified by DDE. Immunoblot analysis also detected a multitude of chemiluminescent bands with a variety of molecular weights in liver homogenates that were harvested from mice treated with DSB. In summary, we have successfully raised polyclonal antibodies to detect protein adducts derived from DDE.

PMID- 29569915 TI - Molecular Facts on the Structure and Dynamics of Electrolyte Species in Cu-Cl Cycle for Hydrogen Generation: An Insight from Molecular Dynamic Simulations. AB - The Cu complex, which is the key chemical species in well-known Cu-Cl hybrid thermochemical cycles and also in numerous metal hydrometallurgical and sedimentary deposit processes, displays a wide variety of structural and dynamical characteristics that are further complicated by the presence of multiple oxidation states of Cu ions with different coordination chemistries, therefore they are difficult to explore from experiments alone. In this article, an attempt has been made to understand the coordination behavior of the Cu complex using MD simulations. The study provides compelling evidence of the experimentally observed multiple stoichiometries of Cu ions, i.e., 1:6:0, 1:5:1, and 1:4:2 for Cu+:H2O:Cl- and 1:6:0 for Cu2+:H2O:Cl-. The presence of the anionic Cu complex, [Cu+Cl2]-.2H2O, [Cu+Cl2]-.3H2O, [Cu2+Cl3]-.H2O, and [Cu2+Cl3]-.2H2O, was captured in the presence of excess chloride ions. Furthermore, the probability distribution profiles have been estimated to determine the most possible complex in the considered systems. The results establish structural and dynamical reformation of the Cu complex with change in the salt concentration or variation in the solvent medium in which they are dissolved. Moreover, the structure and kinetics of the Cu ions in the Cu-Cl electrolyzer have been explored over a large range of the electric field by extending the simulated systems for varied strengths of the electric fields. It has been observed that with an increase in the strength of the electric field, the water molecules lose their coordination strength with central Cu ions, which, on the other hand, results in a significant change in the structure of the captured complex. The diffusion dynamics of the ions is altered while applying the electric field, which is furthermore modified while increasing the strength of electric field beyond a critical limit. In fact, the diffusion mechanism of the ions was seen to be transformed from Brownian-like to linear motion and then to hopping diffusion with the increasing strength of the electric field. To the best of our knowledge, this is the first time when the multiple oxidation states of the Cu ion are explored using MD simulations, and the coexisting pictures of the multiple coordinations and the solvent effects have been clearly revealed. Also to date, the present article is the first one to report the insights of the structure and the dynamics of the ions in the Cu-Cl electrolyzer over a wide range of the electric field. The present studies will be very helpful in understanding the mechanism involved in numerous metal hydrometallurgical and sedimentary deposit processes and to comprehend the analogies involved in the electrode reactions of the Cu-Cl cycle for hydrogen generation. PMID- 29569916 TI - Mechanistic Exploration of the Competition Relationship between a Ketone and C?C, C?N, or C?S Bond in the Rh(III)-Catalyzed Carbocyclization Reactions. AB - The introduction of a C?O, C?C, C?S, or C?N bond has emerged as an effective strategy for carbocycle synthesis. A computational mechanistic study of Rh(III) catalyzed coupling of alkynes with enaminones, sulfoxonium ylides, or alpha carbonyl-nitrones was carried out. Our results uncover the roles of dual directing groups in the three substrates and confirm that the ketone acts as the role of the directing group while the C?C, C?N, or C?S bond serves as the cyclization site. By comparing the coordination of the ketone versus the C?C, C?N, or C?S bond, as well as the chemoselectivity concerning the six- versus five membered formation, a competition relationship is revealed within the dual directing groups. Furthermore, after the alkyne insertion, instead of the originally proposed direct reductive elimination mechanism, the ketone enolization is found to be essential prior to the reductive elimination. The following C(sp2)-C(sp2) reductive elimination is more favorable than the C(sp3) C(sp2) formation, which can be explained by the aromaticity difference in the corresponding transition states. The substituent effect on controlling the selectivity was also discussed. PMID- 29569917 TI - Terminal Sugar Moiety Determines Immunomodulatory Properties of Poly(propyleneimine) Glycodendrimers. AB - Poly(propyleneimine) dendrimers fully surface-modified with disaccharide moieties (maltose, cellobiose, and lactose) designed to mimic natural lectin receptor ligands were tested for their bioactivity in two myeloid cell lines: THP-1 and HL 60. Depending on the sugar modification, we observed variable activation of NF kappaB, AP-1, and NF-AT signaling pathways: lactose-coated dendrimers had the strongest impact on marker gene expression and most signaling events with the notable exception of NF-kappaB activation in THP-1 cells. The two cell lines showed an overall similar pattern of transcription factor and gene expression activation upon treatment with glycodendrimers, suggesting the involvement of galectin and C-type lectin receptor types. An important result of this action was the overexpression of CD40 and IL8 genes, potentially leading to an activated, proinflammatory phenotype in the monocyte/macrophage cell lineage. These pharmacodynamic characteristics of glycodendrimers need to be taken into account during their pharmaceutical applications both in drug delivery and direct immunomodulation. PMID- 29569918 TI - Sialyltransferase-Based Chemoenzymatic Histology for the Detection of N- and O Glycans. AB - Profiling specific glycans in histopathological samples is hampered by the lack of selective and sensitive tools for their detection. Here, we report on the development of chemoenzymatic histology of membrane polysaccharide (CHoMP)-based methods for the detection of O- and N-linked glycans on tissue sections via the use of sialyltransferases ST3Gal1 and ST6Gal1, respectively. Combining these two methods, we developed tandem labeling and double labeling strategies that permit the detection of unsialylated and sialylated glycans or the detection of O- and N linked glycans on the same tissue section, respectively. We applied these methods to screen murine tissue specimens, human multiple-organ cancer arrays, and lymphoma and prostate cancer arrays. Using tandem labeling with ST6Gal1 to analyze N-glycans in a prostate cancer array, we found striking differences in expression patterns of both sialylated and unsialylated N-glycans between cancerous and healthy samples. Such differences were also observed between normal tissue from healthy donors and healthy tissue adjacent to tumors. Our double labeling technique identified significant differences in unsialylated O-glycans between B-cell and T-cell lymphomas and between B-cell lymphomas and normal adjacent lymph nodes. Remarkable differences were also detected between adjacent lymph nodes and spleen tissue samples. These new chemoenzymatic histology methods therefore provide valuable tools for the analysis of glycans in clinically relevant tissue samples. PMID- 29569919 TI - Carbon Nitride Nanothread Crystals Derived from Pyridine. AB - Carbon nanothreads are a new one-dimensional sp3 carbon nanomaterial. They assemble into hexagonal crystals in a room temperature, nontopochemical solid state reaction induced by slow compression of benzene to 23 GPa. Here we show that pyridine also reacts under compression to form a well-ordered sp3 product: C5NH5 carbon nitride nanothreads. Solid pyridine has a different crystal structure from solid benzene, so the nontopochemical formation of low-dimensional crystalline solids by slow compression of small aromatics may be a general phenomenon that enables chemical design of properties. The nitrogen in the carbon nitride nanothreads may improve processability, alters photoluminescence, and is predicted to reduce the bandgap. PMID- 29569920 TI - Molecular Insights into Arctic Soil Organic Matter Degradation under Warming. AB - Molecular composition of the Arctic soil organic carbon (SOC) and its susceptibility to microbial degradation are uncertain due to heterogeneity and unknown SOC compositions. Using ultrahigh-resolution mass spectrometry, we determined the susceptibility and compositional changes of extractable dissolved organic matter (EDOM) in an anoxic warming incubation experiment (up to 122 days) with a tundra soil from Alaska (United States). EDOM was extracted with 10 mM NH4HCO3 from both the organic- and mineral-layer soils during incubation at both 2 and 8 degrees C. Based on their O:C and H:C ratios, EDOM molecular formulas were qualitatively grouped into nine biochemical classes of compounds, among which lignin-like compounds dominated both the organic and the mineral soils and were the most stable, whereas amino sugars, peptides, and carbohydrate-like compounds were the most biologically labile. These results corresponded with shifts in EDOM elemental composition in which the ratios of O:C and N:C decreased, while the average C content in EDOM, molecular mass, and aromaticity increased after 122 days of incubation. This research demonstrates that certain EDOM components, such as amino sugars, peptides, and carbohydrate-like compounds, are disproportionately more susceptible to microbial degradation than others in the soil, and these results should be considered in SOC degradation models to improve predictions of Arctic climate feedbacks. PMID- 29569921 TI - Computational Study of the Structure and Degradation Products of Alloxydim Herbicide. AB - Density functional theory calculations allowed us to study alloxydim herbicide and to identify the most stable conformers, the factors that governs their stability, and the interconversion mechanisms among the most relevant conformers. The degradation chain involves, as a first step, the cleavage of the N-O bond and the formation of a stable intermediate difficult to characterize experimentally. The study performed also allowed us to identify the properties of this elusive intermediate and to determine that the dominant fragmentation process in the gas phase is the homolytic fragmentation. Stability of alloxydim conformers and homolytic fragments were also assessed in the water phase. Computed IR spectra were consistent with those observed experimentally. PMID- 29569922 TI - Melting of the Au20 Gold Cluster: Does Charge Matter? AB - We investigate the dependence upon the charge of the heat capacities of magic gold cluster Au20 obtained from density functional-based tight binding theory within parallel tempering molecular dynamics and the multiple histogram method. The melting temperatures, determined from the heat capacity curves, are found to be 1102 K for neutral Au20 and only 866 and 826 K for Au20+ and Au20-. Both the canonical and the microcanonical aspects of the transition are discussed. A convex intruder, associated with a negative heat capacity, is evidenced in the microcanonical entropy in the case of the neutral cluster but is absent in the melting processes of the ions. The present work shows that a single charge quantitatively affects the thermal properties of the gold 20mer. PMID- 29569923 TI - Correlation between Gas Bubble Formation and Hydrogen Evolution Reaction Kinetics at Nanoelectrodes. AB - We report the correlation between H2 gas bubble formation potential and hydrogen evolution reaction (HER) activity for Au and Pt nanodisk electrodes (NEs). Microkinetic models were formulated to obtain the HER kinetic information for individual Au and Pt NEs. We found that the rate-determining steps for the HER at Au and Pt NEs were the Volmer step and the Heyrovsky step, respectively. More interestingly, the standard rate constant ( k0) of the rate-determining step was found to vary over 2 orders of magnitude for the same type of NEs. The observed variations indicate the HER activity heterogeneity at the nanoscale. Furthermore, we discovered a linear relationship between bubble formation potential ( Ebubble) and log( k0) with a slope of 125 mV/decade for both Au and Pt NEs. As log ( k0) increases, Ebubble shifts linearly to more positive potentials, meaning NEs with higher HER activities form H2 bubbles at less negative potentials. Our theoretical model suggests that such linear relationship is caused by the similar critical bubble formation condition for Au and Pt NEs with varied sizes. Our results have potential implications for using gas bubble formation to evaluate the HER activity distribution of nanoparticles in an ensemble.

AB - The well known organic semiconductor C60 is attracting renewed attention due to its centimeter-long electron diffusion length and high performance of solar cells containing 95% fullerene, yet its photophysical properties remain poorly understood. We elucidate the dynamics of Frenkel and intermolecular (inter-C60) charge-transfer (CT) excitons in neat and diluted C60 films from high-quality femtosecond transient absorption (TA) measurements performed at low fluences and free from oxygen or pump-induced photodimerization. We find from preferential excitation of either species that the CT excitons give rise to a strong electro absorption (EA) signal but are extremely short-lived. The Frenkel exciton relaxation and triplet yield strongly depend on the C60 aggregation. Finally, TA measurements on full devices with applied electric field allow us to optically monitor the dissociation of CT excitons into free charges for the first time and to demonstrate the influence of cluster size on the spectral signature of the C60 anion. PMID- 29569925 TI - Toward a Ferrous Iron-Cleavable Linker for Antibody-Drug Conjugates. AB - Antibody-drug conjugates (ADCs) are antigen-targeted therapeutics that employ antibodies to deliver potent, cytotoxic effectors to cells with potentially high specificity. While promising clinical results have been achieved, significant pitfalls remain including internalization of ADCs in nontargeted cells expressing target antigen, which can limit therapeutic windows. Novel ADC linkers that are cleaved selectively in cancer cells but not in normal cells could minimize collateral damage caused by ADC uptake in nontargeted tissues. Here, we describe a prototypical ADC linker based on an Fe(II)-reactive 1,2,4-trioxolane scaffold (TRX) that by itself has demonstrated tumor-selective activity in preclinical cancer models. We prepared TRX-linked ADCs by site-selective conjugation to two sites in trastuzumab and compared their activity in Her2 positive and negative cells to ADC controls based on established linker chemistry. Our results confirm that the TRX moiety efficiently releases its payload following ADC uptake, affording picomolar potencies in antigen-positive cells. We also identified a destabilizing interaction between these initial TRX linkers and nearby antibody residues and suggest an approach to improve upon these prototypical designs. PMID- 29569926 TI - Intracellular Delivery of Nanomaterials via an Inertial Microfluidic Cell Hydroporator. AB - The introduction of nanomaterials into cells is an indispensable process for studies ranging from basic biology to clinical applications. To deliver foreign nanomaterials into living cells, traditionally endocytosis, viral and lipid nanocarriers or electroporation are mainly employed; however, they critically suffer from toxicity, inconsistent delivery, and low throughput and are time consuming and labor-intensive processes. Here, we present a novel inertial microfluidic cell hydroporator capable of delivering a wide range of nanomaterials to various cell types in a single-step without the aid of carriers or external apparatus. The platform inertially focuses cells into the channel center and guides cells to collide at a T-junction. Controlled compression and shear forces generate transient membrane discontinuities that facilitate passive diffusion of external nanomaterials into the cell cytoplasm while maintaining high cell viability. This hydroporation method shows superior delivery efficiency, is high-throughput, and has high controllability; moreover, its extremely simple and low-cost operation provides a powerful and practical strategy in the applications of cellular imaging, biomanufacturing, cell-based therapies, regenerative medicine, and disease diagnosis. PMID- 29569927 TI - Molecular Origin of Photoprotection in Cyanobacteria Probed by Watermarked Femtosecond Stimulated Raman Spectroscopy. AB - Photoprotection is fundamental in photosynthesis to avoid oxidative photodamage upon excess light exposure. Excited chlorophylls (Chl) are quenched by carotenoids, but the precise molecular origin remains controversial. The cyanobacterial HliC protein belongs to the Hlip family ancestral to plant light harvesting complexes, and binds Chl a and beta-carotene in 2:1 ratio. We analyzed HliC by watermarked femtosecond stimulated Raman spectroscopy to follow the time evolution of its vibrational modes. We observed a 2 ps rise of the C?C stretch band of the 2Ag- (S1) state of beta-carotene upon Chl a excitation, demonstrating energy transfer quenching and fast excess-energy dissipation. We detected two distinct beta-carotene conformers by the C?C stretch frequency of the 2Ag- (S1) state, but only the beta-carotene whose 2Ag- energy level is significantly lowered and has a lower C?C stretch frequency is involved in quenching. It implies that the low carotenoid S1 energy that results from specific pigment protein or pigment-pigment interactions is the key property for creating a dissipative energy channel. We conclude that watermarked femtosecond stimulated Raman spectroscopy constitutes a promising experimental method to assess energy transfer and quenching mechanisms in oxygenic photosynthesis. PMID- 29569928 TI - Exciton-Dominated Core-Level Absorption Spectra of Hybrid Organic-Inorganic Lead Halide Perovskites. AB - In a combined theoretical and experimental work, we investigate X-ray absorption near-edge structure spectroscopy of the I L3 and the Pb M5 edges of the methylammonium lead iodide (MAPbI3) hybrid inorganic-organic perovskite and its binary phase PbI2. The absorption onsets are dominated by bound excitons with sizable binding energies of a few hundred millielectronvolts and pronounced anisotropy. The spectra of both materials exhibit remarkable similarities, suggesting that the fingerprints of core excitations in MAPbI3 are essentially given by its inorganic component, with negligible influence from the organic groups. The theoretical analysis complementing experimental observations provides the conceptual insights required for a full characterization of this complex material. PMID- 29569929 TI - An Isolable and Bench-Stable Epoxidizing Reagent Based on Triazine: Triazox. AB - A new triazine-based oxidizing reagent, 2-hydroperoxy-4,6-diphenyl-1,3,5-triazine (Triazox), has been developed. The reagent can be synthesized from inexpensive starting materials and is a bench-stable solid that is isolable in pure form. Epoxidation of alkenes possessing acid-sensitive functionalities using Triazox proceeded in good to excellent yields. The accompanying nonacidic triazinone coproduct can be easily removed by filtration. These features indicate that Triazox is a practically useful oxidizing reagent. PMID- 29569930 TI - Double Barrel Nanopores as a New Tool for Controlling Single-Molecule Transport. AB - The ability to control the motion of single biomolecules is key to improving a wide range of biophysical and diagnostic applications. Solid-state nanopores are a promising tool capable of solving this task. However, molecular control and the possibility of slow readouts of long polymer molecules are still limited due to fast analyte transport and low signal-to-noise ratios. Here, we report on a novel approach of actively controlling analyte transport by using a double-nanopore architecture where two nanopores are separated by only a ~ 20 nm gap. The nanopores can be addressed individually, allowing for two unique modes of operation: (i) pore-to-pore transfer, which can be controlled at near 100% efficiency, and (ii) DNA molecules bridging between the two nanopores, which enables detection with an enhanced temporal resolution (e.g., an increase of more than 2 orders of magnitude in the dwell time) without compromising the signal quality. The simplicity of fabrication and operation of the double-barrel architecture opens a wide range of applications for high-resolution readout of biological molecules.

AB - The synthesis of sodium alpha-aminoalkanesulfinates and their synthetic utility as alpha-aminoalkyl radical precursors are reported. A variety of alpha aminoalkanesulfinates were readily obtained from the reaction between the anions of N-Boc-protected alkylamines and 1,4-diazabicyclo[2.2.2]octanebis(sulfur dioxide). Treatment of sodium alpha-aminoalkanesulfinates with (diacetoxyiodo)benzene easily generated the corresponding alpha-aminoalkyl radicals under mild conditions, which were then applied in radical 1,2-addition to imines, radical 1,4-addition to electron-deficient olefins, and radical addition/cyclization to 2-isocyanobiphenyls.

AB - An unprecedented aryne 1,2,3-trifunctionalization protocol from 2,6 bis(silyl)aryl triflates was developed under transition-metal-free conditions. The reaction of generated 3-silylaryne with both pyridine N-oxide and N hydroxylamide afforded o-silyl triflate/tosylate in a one-pot transformation, allowing the formation of 2,3-aryne precursors with various vicinal pyridinyl/amido substituents. These pyridinyl-substituted 2,3-aryne intermediates exhibit a broad scope of reactivity with diverse arynophiles in good yields and high selectivity. PMID- 29569933 TI - Thoracic-abdominal imaging with a novel dual-layer spectral detector CT: intra individual comparison of image quality and radiation dose with 128-row single energy acquisition. AB - BACKGROUND: A novel, multi-energy, dual-layer spectral detector computed tomography (SDCT) is commercially available now with the vendor's claim that it yields the same or better quality of polychromatic, conventional CT images like modern single-energy CT scanners without any radiation dose penalty. PURPOSE: To intra-individually compare the quality of conventional polychromatic CT images acquired with a dual-layer spectral detector (SDCT) and the latest generation 128 row single-energy-detector (CT128) from the same manufacturer. MATERIAL AND METHODS: Fifty patients underwent portal-venous phase, thoracic-abdominal CT scans with the SDCT and prior CT128 imaging. The SDCT scanning protocol was adapted to yield a similar estimated dose length product (DLP) as the CT128. Patient dose optimization by automatic tube current modulation and CT image reconstruction with a state-of-the-art iterative algorithm were identical on both scanners. CT image contrast-to-noise ratio (CNR) was compared between the SDCT and CT128 in different anatomic structures. Image quality and noise were assessed independently by two readers with 5-point-Likert-scales. Volume CT dose index (CTDIvol), and DLP were recorded and normalized to 68 cm acquisition length (DLP68). RESULTS: The SDCT yielded higher mean CNR values of 30.0% +/- 2.0% (26.4 32.5%) in all anatomic structures ( P < 0.001) and excellent scores for qualitative parameters surpassing the CT128 (all P < 0.0001) with substantial inter-rater agreement (kappa >= 0.801). Despite adapted scan protocols the SDCT yielded lower values for CTDIvol (-10.1 +/- 12.8%), DLP (-13.1 +/- 13.9%), and DLP68 (-15.3 +/- 16.9%) than the CT128 (all P < 0.0001). CONCLUSION: The SDCT scanner yielded better CT image quality compared to the CT128 and lower radiation dose parameters.

AB - Doxorubicin (DOX) is an effective anticancer drug which is widely used in clinical treatment. However, the severe cardiotoxicity limits its use. Thus, it is an urgent need to attenuate the toxicity of DOX without impairing its efficacy. Many studies show that Se may protect normal tissues from damages of some anticancer drugs. Recently, Se@SiO2 nanocomposites emerges as better substitutes for direct element Se in treatment of cancer cells for their ideal biocompatibility. In the present article, we synthesized Se@SiO2 nanocomposites and confirmed their characterization according to previous studies. We accomplished a conjunctive use of Se@SiO2 nanocomposites with DOX then explored the toxicity and efficacy of this combination. In the in vivo experiments, the survival rate of mice with DOX treatment was significantly increased by Se@SiO2. And Se@SiO2 has few interference to the therapeutic effect of DOX. Particularly, Se@SiO2 significantly attenuated DOX-induced myocardial tissue damage (serum index, apoptosis index, western-blot index) and protected mice from reduction in LVEF induced by DOX in mice model. In summary, we concluded that the protective effect of Se@SiO2 in DOX-induced cardiotoxicity was possibly attributable to the inhibition of ROS production, showing great potential of Se@SiO2 nanocomposite in the clinical use of DOX. PMID- 29569934 TI - Intergenic and intronic DNA hypomethylated regions as putative regulators of imprinted domains. AB - AIM: To investigate the regulatory potential of intergenic/intronic hypomethylated regions (iHMRs) within imprinted domains. MATERIALS & METHODS: Based on the preliminary results of the histone modification and conservation profiles, we conducted reporter assays on the Peg3 and H19 domain iHMRs. The in vitro results were confirmed by the in vivo deletion of Peg3-iHMR designed to test its function in the Peg3 imprinted domain. RESULTS & CONCLUSION: Initial bioinformatic analyses suggested that some iHMRs may be noncanonical enhancers for imprinted genes. Consistent with this, Peg3- and H19-iHMRs showed context dependent promoter and enhancer activity. Further, deletion of Peg3-iHMR resulted in allele- and sex-specific misregulation of several imprinted genes within the domain. Taken together, these results suggest that some iHMRs may function as domain-wide regulators for the associated imprinted domains. PMID- 29569936 TI - Target discovery focused approaches to overcome bottlenecks in the exploitation of antimycobacterial natural products. AB - Tuberculosis is a major global health hazard. The search for new antimycobacterials has focused on such as screening combinational chemistry libraries or designing chemicals to target predefined pockets of essential bacterial proteins. The relative ineffectiveness of these has led to a reappraisal of natural products for new antimycobacterial drug leads. However, progress has been limited, we suggest through a failure in many cases to define the drug target and optimize the hits using this information. We highlight methods of target discovery needed to develop a drug into a candidate for clinical trials. We incorporate these into suggested analysis pipelines which could inform the research strategies to accelerate the development of new drug leads from natural products. PMID- 29569937 TI - The role of microRNAs and nanoparticles in ovarian cancer: a review. AB - MicroRNAs (miRNAs) have had a revolutionary impact on cancer research over the recent years. They emerge as important players in tumourigenesis, leading to a paradigm shift in oncology. Ovarian cancer is the leading cause of death among gynaecologic malignancies. Therefore, there is a strong need for prognostic and predictive markers for early diagnosis which helps optimize and personalize treatment. Asymptomatically, ovarian cancer is often diagnosed at advanced and incurable stages. Efficient targeting and sustained release of miRNAs/anti-miRNAs using nanoparticles conjugated with antibodies and/or peptides could reduce the required therapeutic dosage while minimizing systemic and cellular toxicity. Given miRNAs importance in clinical oncology, here we focus on the development of miRNA nanoformulations to achieve enhanced cellular uptake, bioavailability and accumulation at the tumour site. Although many obstacles need to be overcome, miRNA therapy could be a powerful tool for ovarian cancer prevention and treatment. In this review, we discuss about the emerging roles of miRNAs in various aspects of ovarian cancer. PMID- 29569938 TI - New opportunities for GPCR allosteric modulators.

AB - Male youth (8-18 years) with intellectual disability (ID) demonstrate motor proficiency below age-related competence capacities for typically developing youth. Whether below-criteria motor proficiency also exists for females with ID is not known. The purpose of this study was to determine if sex-specific differences exist in motor proficiency for youth with ID. The Bruininks-Oseretsky Test of Motor Proficiency was used to measure motor proficiency: six items for upper limb coordination, seven items for balance, and six items for bilateral coordination. One hundred and seventy-two (172) males and 85 females with ID but without Down syndrome were divided into five age groups for comparative purposes: 8-10, 11-12, 13-14, 15-16, and 17-21 years. Males scored sufficiently higher than females to suggest that sex data should not be combined to established Bruininks Oseretsky Test of Motor Proficiency standards for upper limb coordination, balance, and bilateral coordination subtests. PMID- 29569941 TI - Complexities of post-transcriptional regulation and the modeling of ceRNA crosstalk. AB - Control of gene and protein expression is required for cellular homeostasis and is disrupted in disease. Following transcription, mRNA turnover and translation is modulated, most notably by microRNAs (miRNAs). This modulation is controlled by transcriptional and post-transcriptional events that alter the availability of miRNAs for target binding. Recent studies have proposed that some transcripts - termed competitive endogenous RNAs (ceRNAs) - sequester a miRNA and diminish its repressive effects on other transcripts. Such ceRNAs thus mutually alter each other's abundance by competing for binding to a common set of miRNAs. Some question the relevance of ceRNA crosstalk, arguing that an individual transcript, when its abundance lies within a physiological range of gene expression, will fail to compete for miRNA binding due to the high abundance of other miRNA binding sites across the transcriptome. Despite this, some experimental evidence is consistent with the ceRNA hypothesis. In this review, we draw upon existing data to highlight mechanistic and theoretical aspects of ceRNA crosstalk. Our intent is to propose how understanding of ceRNA crosstalk mechanisms can be improved and what evidence is required to demonstrate a ceRNA mechanism. A greater understanding of factors affecting ceRNA crosstalk should shed light on its relevance in physiological states. PMID- 29569943 TI - Whole-Body-Vibration Training and Balance in Recreational Athletes With Chronic Ankle Instability. AB - CONTEXT: Deficits in the propioceptive system of the ankle contribute to chronic ankle instability (CAI). Recently, whole-body-vibration (WBV) training has been introduced as a preventive and rehabilitative tool. OBJECTIVE: To evaluate how a 6-week WBV training program on an unstable surface affected balance and body composition in recreational athletes with CAI. DESIGN: Randomized controlled clinical trial. SETTING: Research laboratory. PATIENTS OR OTHER PARTICIPANTS: Fifty recreational athletes with self-reported CAI were randomly assigned to a vibration (VIB), nonvibration (NVIB), or control group. INTERVENTION(S): The VIB and NVIB groups performed unilateral balance training on a BOSU 3 times weekly for 6 weeks. The VIB group trained on a vibration platform, and the NVIB group trained on the floor. MAIN OUTCOME MEASURE(S): We assessed balance using the Biodex Balance System and the Star Excursion Balance Test (SEBT). Body composition was measured by dual-energy x-ray absorptiometry. RESULTS: After 6 weeks of training, improvements on the Biodex Balance System occurred only on the Overall Stability Index ( P = .01) and Anterior-Posterior Stability Index ( P = .03) in the VIB group. We observed better performance in the medial ( P = .008) and posterolateral ( P = .04) directions and composite score of the SEBT in the VIB group ( P = .01) and in the medial ( P < .001), posteromedial ( P = .002), and posterolateral ( P = .03) directions and composite score of the SEBT in the NVIB group ( P < .001). No changes in body composition were found for any of the groups. CONCLUSIONS: Only the VIB group showed improvements on the Biodex Balance System, whereas the VIB and NVIB groups displayed better performance on the SEBT. PMID- 29569944 TI - Shoulder Taping and Neuromuscular Control. AB - CONTEXT: Scapular taping can offer clinical benefit to some patients with shoulder pain; however, the underlying mechanisms are unclear. Understanding these mechanisms may guide the development of treatment strategies for managing neuromusculoskeletal shoulder conditions. OBJECTIVE: To examine the mechanisms underpinning the benefits of scapular taping. DESIGN: Descriptive laboratory study. SETTING: University laboratory. PATIENTS OR OTHER PARTICIPANTS: A total of 15 individuals (8 men, 7 women; age = 31.0 +/- 12.4 years, height = 170.9 +/- 7.6 cm, mass = 73.8 +/- 14.4 kg) with no history of shoulder pain. INTERVENTION(S): Scapular taping. MAIN OUTCOME MEASURE(S): Surface electromyography (EMG) was used to assess the (1) magnitude and onset of contraction of the upper trapezius (UT), lower trapezius (LT), and serratus anterior relative to the contraction of the middle deltoid during active shoulder flexion and abduction and (2) corticomotor excitability (amplitude of motor evoked potentials from transcranial magnetic stimulation) of these muscles at rest and during isometric abduction. Active shoulder-flexion and shoulder abduction range of motion were also evaluated. All outcomes were measured before taping, immediately after taping, 24 hours after taping with the original tape on, and 24 hours after taping with the tape removed. RESULTS: Onset of contractions occurred earlier immediately after taping than before taping during abduction for the UT (34.18 +/- 118.91 milliseconds and 93.95 +/- 106.33 milliseconds, respectively, after middle deltoid contraction; P = .02) and during flexion for the LT (110.02 +/- 109.83 milliseconds and 5.94 +/- 92.35 milliseconds, respectively, before middle deltoid contraction; P = .06). These changes were not maintained 24 hours after taping. Mean motor-evoked potential onset of the middle deltoid was earlier at 24 hours after taping (tape on = 7.20 +/- 4.33 milliseconds) than before taping (8.71 +/- 5.24 milliseconds, P = .008). We observed no differences in peak root mean square EMG activity or corticomotor excitability of the scapular muscles among any time frames. CONCLUSIONS: Scapular taping was associated with the earlier onset of UT and LT contractions during shoulder abduction and flexion, respectively. Altered corticomotor excitability did not underpin earlier EMG onsets of activity after taping in this sample. Our findings suggested that the optimal time to engage in rehabilitative exercises to facilitate onset of trapezius contractions during shoulder movements may be immediately after tape application.

PMID- 29569946 TI - Surface-Enhanced Raman Scattering (SERS) in Microbiology: Illumination and Enhancement of the Microbial World. AB - The microbial world forms a huge family of organisms that exhibit the greatest phylogenetic diversity on Earth and thus colonize virtually our entire planet. Due to this diversity and subsequent complex interactions, the vast majority of microorganisms are involved in innumerable natural bioprocesses and contribute an absolutely vital role toward the maintenance of life on Earth, whilst a small minority cause various infectious diseases. The ever-increasing demand for environmental monitoring, sustainable ecosystems, food security, and improved healthcare systems drives the continuous search for inexpensive but reproducible, automated and portable techniques for detection of microbial isolates and understanding their interactions for clinical, environmental, and industrial applications and benefits. Surface-enhanced Raman scattering (SERS) is attracting significant attention for the accurate identification, discrimination and characterization and functional assessment of microbial cells at the single cell level. In this review, we briefly discuss the technological advances in Raman and Fourier transform infrared (FT-IR) instrumentation and their application for the analysis of clinically and industrially relevant microorganisms, biofilms, and biological warfare agents. In addition, we summarize the current trends and future prospects of integrating Raman/SERS-isotopic labeling and cell sorting technologies in parallel, to link genotype-to-phenotype in order to define community function of unculturable microbial cells in mixed microbial communities which possess admirable traits such as detoxification of pollutants and recycling of essential metals. PMID- 29569947 TI - Tivanisiran, a novel siRNA for the treatment of dry eye disease. AB - INTRODUCTION: Dry eye disease (DED) is characterized by an alteration of the tear film with ocular inflammation and neurosensory abnormalities. The main clinical signs of this condition are tear instability and ocular damage. Although DED has gained significant attention in the past few years, limited prescription treatment options are available for patients. Areas covered: The current manuscript summarizes the pre-clinical and clinical development of tivanisiran, a novel small interfering oligonucleotide of RNA (siRNA) used for the treatment of DED. Tivanisiran was designed to silence Transient Receptor Potential Vanilloid 1 (TRPV1); herein the chemistry and mechanism of action of this new compound is also described. Expert opinion: Drugs currently on the market mostly target the inflammatory component of the disease and show only partial efficacy. New compounds addressing other aspects of the disease would provide significant advantages and contribute to a more personalized treatment of the disease. Tivanisiran has been designed to reduce ocular discomfort and pain, and was shown to improve ocular hyperemia and tear quality in human and animal models. Consequently, if the results of the ongoing and future clinical trials meet their study endpoints, tivanisiran could be submitted to obtain approval for the treatment of DED. PMID- 29569948 TI - Targeting p53 as a promising therapeutic option for cancer by re-activating the wt or mutant p53's tumor suppression. AB - p53 protein, a product of the TP53 tumor suppressor gene, controls the cellular genome's integrity and is an important regulator of cell cycling, proliferation, apoptosis and metabolism. Mutations of TP53 or inactivation of its gene product are among the first events initiating malignant transformation. The consequent loss of control over the cell cycle, resulting in accelerated cell proliferation and facilitating metabolic reprogramming, gives the initiated (premalignant) cells numerous advantages over healthy cells. Interestingly, p53 status is not only an important marker in cancer diagnosis; it has also become a promising target of personalized therapy. Depending on the TP53 status different therapeutic options have been developed. (Re)-activation of p53 functionality in cancer cells offers promising new alternatives to existing oncological therapies. PMID- 29569949 TI - Altered expression of transcription factors IRF4 and IRF8 in peripheral blood B cells is associated with clinical severity and circulating plasma cells frequency in patients with myasthenia gravis. AB - Previous studies have shown that interferon regulatory factor-4 (IRF4) and IRF8 play critical but distinct roles in the differentiation of B cells into plasma cells (PCs). In the present study, we aimed to measure the expression levels of IRF4 and IRF8 in B cells from patients with myasthenia gravis (MG) and to investigate whether the expression of IRF4 and IRF8 associates with pathogenesis of MG. A total of 35 anti-acetylcholine receptor (AChR) antibody (Ab)-positive patients with MG [20 generalized MG (GMG) and 15 ocular MG (OMG) and 25 healthy donors were recruited in this study. The quantitative myasthenia gravis score (QMGS) was used to evaluate the clinical severity. Real-time PCR and Western blot were used to measure the levels of IRF4 and IRF8 expressed in peripheral blood B cells. Peripheral blood CD138+ PCs were assayed by flow cytometry. Our data demonstrated that the mRNA/protein levels of IRF4 and IRF8 were significantly higher and lower, respectively, in patients with OMG/GMG groups compared with healthy controls. In addition, IRF4 expression was significantly higher and IRF8 expression was significantly lower in GMG group than in OMG group. Pearson's correlation analysis revealed that IRF8 expression was negatively correlated with clinical severity, PCs frequency and anti-AChR Ab levels, while IRF4 expression and IRF4/IRF8 ratio was positively correlated with these parameters in two MG subgroups. Finally, glucocorticoid treatment can relieve the imbalance of IRF4/IRF8 in peripheral blood B cells, and this restoration is accompanied by reduced PCs frequency and clinical symptoms. These evidences suggest that IRF4 and IRF8 are important in the counter-balancing mechanisms controlling differentiation of PCs in MG. The disruption of the balanced IRF4/IFR8 ratio in B cells may play important roles in the pathogenesis of MG and offer a promising therapeutic target for the development of novel immunotherapy for MG patients.

Due to a lack of conceptual clarity, we present a concept analysis of decision fatigue. A search of the term "decision fatigue" was conducted across seven research databases, which yielded 17 relevant articles. The authors identified three antecedent themes (decisional, self-regulatory, and situational) and three attributional themes (behavioral, cognitive, and physiological) of decision fatigue. However, the extant literature failed to adequately describe consequences of decision fatigue. This concept analysis provides needed conceptual clarity for decision fatigue, a concept possessing relevance to nursing and allied health sciences.

AB - OBJECTIVE: Dexketoprofen trometamol is a modified non-selective COX inhibitor with a rapid onset of action that is available as both oral and parenteral formulations. The aim of this narrative review was to assess the efficacy and tolerability/safety of dexketoprofen trometamol in acute pain states using the best available published scientific evidence (randomized controlled clinical trials and systematic reviews/meta-analyses). METHODS: Literature retrieval was performed via Medline, Embase and the Cochrane Library (from inception up to March 2017) using combinations of the terms "randomized controlled trials", "dexketoprofen", "celecoxib", "etoricoxib", "parecoxib" and "acute pain". RESULTS: Single-dose dexketoprofen trometamol provides effective analgesia in the treatment of acute pain, such as postoperative pain (dental and non-dental surgery), renal colic, acute musculoskeletal disorders and dysmenorrhea, and reduces opioid consumption in the postoperative setting. It has a rapid onset of action (within 30 minutes) and is well tolerated during short-term treatment. Direct comparisons with COX-2 inhibitors are lacking; however, the efficacy and tolerability of single-dose dexketoprofen trometamol appears to be consistent with that seen with celecoxib, etoricoxib and parecoxib in the acute pain setting. CONCLUSION: In conclusion, dexketoprofen trometamol appears to provide similar analgesic efficacy to COX-2 inhibitors when used to treat acute pain, has a rapid onset of action, is well tolerated, and has an opioid-sparing effect when used as part of a multimodal regimen in the acute pain setting.

AB - Chronic Staphylococcus aureus infections are complicated by frequent relapses not only from the development of drug resistance to conventional antibiotics, but also through the formation of persister bacterial cells. Bacterial persisters are in a transient, metabolically inactive state, making conventional antibiotics that target essential cellular growth processes ineffective, resulting in high clinical failure rates of antibiotic chemotherapy. The development of new antibiotics against persistent S. aureus is an urgent issue. Over the last decade, new strategies to identify S. aureus persister-active compounds have been proposed. This review summarizes the proposed targets, antipersister compounds and innovative methods that may augment conventional antibiotics against S. aureus persisters. The reviewed antipersister strategies can be summarized as two broad categories; directly targeting growth-independent targets and potentiating existing, ineffective antibiotics by aiding uptake or accessibility. PMID- 29569954 TI - Nitrosative stress uncovers potent beta2-adrenergic receptor-linked vasodilation further enhanced by blockade of clathrin endosome formation. AB - This study investigated the effect of sodium nitroprusside (SNP) preexposure on vasodilation via the beta-adrenergic receptor (BAR) system. SNP was used as a nitrosative/oxidative proinflammatory insult. Small arterioles were visualized by intravital microscopy in the hamster cheek pouch tissue (isoflurane, n = 45). Control dilation to isoproterenol (EC50: 10-7 mol/l) became biphasic as a function of concentration after 2 min of exposure to SNP (10-4 M), with increased potency at picomolar dilation uncovered and decreased efficacy at the micromolar dilation. Control dilation to curcumin was likewise altered after SNP, but only the increased potency at a low dose was uncovered, whereas micromolar dilation was eliminated. The picomolar dilations were blocked by the potent BAR-2 inverse agonist carazolol (10-9 mol/l). Dynamin inhibition with dynasore mimicked this effect, suggesting that SNP preexposure prevented BAR agonist internalization. Using HeLa cells transfected with BAR-2 tagged with monomeric red fluorescent protein, exposure to 10-8-10-6 mol/l curcumin resulted in internalization and colocalization of BAR-2 and curcumin (FRET) that was prevented by oxidative stress (10-3 mol/l CoCl2), supporting that stress prevented internalization of the BAR agonist with the micromolar agonist. This study presents novel data supporting that distinct pools of BARs are differentially available after inflammatory insult. NEW & NOTEWORTHY Preexposure to an oxidative/nitrosative proinflammatory insult provides a "protective preconditioning" against future oxidative damage. We examined immediate vasoactive and molecular consequences of a brief preexposure via beta-adrenergic receptor signaling in small arterioles. Blocked receptor internalization with elevated reactive oxygen levels coincides with a significant and unexpected vasodilation to beta-adrenergic agonists at picomolar doses. PMID- 29569956 TI - Humoral transfer and intramyocardial signal transduction of protection by remote ischemic perconditioning in pigs, rats, and mice. AB - Remote ischemic perconditioning (RPER) during ongoing myocardial ischemia reduces infarct size. The signal transduction of RPER's cardioprotection is still largely unknown. Anesthetized pigs were therefore subjected to RPER by 4 * 5 min/5 min of hindlimb ischemia-reperfusion during 60 min of coronary occlusion before 3 h of reperfusion. Pigs without RPER served as placebo (PLA). The phosphorylation of Akt and ERK [reperfusion injury salvage kinase (RISK) pathway] and STAT3 [survivor activating factor enhancement (SAFE) pathway] in the area at risk was determined by Western blot analysis. Wortmannin/U0126 or AG490 was used for pharmacological RISK or SAFE blockade, respectively. Pig plasma/plasma dialysate sampled after RPER or PLA, respectively, was transferred to isolated rat and mouse hearts subjected to 30 min/120 min of global ischemia-reperfusion. Mitochondria were isolated from rat hearts at early reperfusion. Isolated mouse cardiomyocytes were subjected to 1 h of hypoxia/5 min of reoxygenation without and with prior plasma dialysate incubation. RPER reduced infarct size in pigs to 21 +/- 15% versus 44 +/- 9% in PLA (percentage of the area at risk, mean +/- SD, P < 0.05) and increased STAT3 phosphorylation at early reperfusion. AG490 but not RISK blockade abolished the protection. RPER plasma/plasma dialysate reduced infarct size in rat (22 +/- 3% of ventricular mass vs. 40 +/- 11% with PLA plasma, P < 0.05) and mouse (29 +/- 4% vs. 63 +/- 8% with PLA plasma dialysate, P < 0.05) hearts and improved mitochondrial function (e.g., increased respiration, ATP formation, and calcium retention capacity and decreased reactive oxygen species formation). RPER dialysate also improved the viability of mouse cardiomyocytes after hypoxia/reoxygenation. RISK or SAFE blockade each abrogated these beneficial effects. NEW & NOTEWORTHY Remote ischemic perconditioning salvages the myocardium in patients with acute infarction. We identified a signal transduction with humoral transfer and STAT3 activation in pigs and an involvement of reperfusion injury salvage kinases and STAT3 in rat and mouse hearts, along with better cardiomyocyte viability and mitochondrial function. PMID- 29569957 TI - Protein tyrosine phosphatase 1B inactivation limits aging-associated heart failure in mice. AB - We have previously shown that protein tyrosine phosphatase 1B (PTP1B) inactivation in mice [PTP1B-deficient (PTP1B-/-) mice] improves left ventricular (LV) angiogenesis, perfusion, remodeling, and function and limits endothelial dysfunction after myocardial infarction. However, whether PTP1B inactivation slows aging-associated cardiovascular dysfunction remains unknown. Wild-type (WT) and PTP1B-/- mice were allowed to age until 18 mo. Compared with old WT mice, in which aging increased the LV mRNA expression of PTP1B, old PTP1B-/- mice had 1) reduced cardiac hypertrophy with decreased LV mRNA levels of hypertrophic markers and atrial and brain natriuretic peptides, 2) lower LV fibrosis (collagen: 16 +/- 3% in WT mice and 5 +/- 3% in PTP1B-/- mice, P < 0.001) with decreased mRNA levels of transforming growth-factor-beta1 and matrix metalloproteinase-2, and 3) higher LV capillary density and lower LV mRNA level of hypoxic inducible factor 1alpha, which was associated over time with a higher rate of proangiogenic M2 type macrophages and a stable LV mRNA level of VEGF receptor-2. Echocardiography revealed an age-dependent LV increase in end-diastolic volume in WT mice together with alterations of fractional shortening and diastole (transmitral Doppler E-to A wave ratio). Invasive hemodynamics showed better LV systolic contractility and better diastolic compliance in old PTP1B-/- mice (LV end-systolic pressure-volume relation: 13.9 +/- 0.9 in WT mice and 18.4 +/- 1.6 in PTP1B-/- mice; LV end diastolic pressure-volume relation: 5.1 +/- 0.8 mmHg/relative volume unit in WT mice and 1.2 +/- 0.3 mmHg/relative volume unit in PTP1B-/- mice, P < 0.05). In addition, old PTP1B-/- mice displayed a reduced amount of LV reactive oxygen species. Finally, in isolated resistance mesenteric arteries, PTP1B inactivation reduced aging-associated endothelial dysfunction (flow-mediated dilatation: -0.4 +/- 2.1% in WT mice and 8.2 +/- 2.8% in PTP1B-/- mice, P < 0.05). We conclude that PTP1B inactivation slows aging-associated LV remodeling and dysfunction and reduces endothelial dysfunction in mesenteric arteries. NEW & NOTEWORTHY The present study shows that protein tyrosine phosphatase 1B inactivation in aged mice improves left ventricular systolic and diastolic function associated with reduced adverse cardiac remodeling (hypertrophy, fibrosis, and capillary rarefaction) and limits vascular endothelial dysfunction. This suggests that protein tyrosine phosphatase 1B inhibition could be an interesting treatment approach in age-related cardiovascular dysfunction. PMID- 29569958 TI - Influence of long-term treatment with glyceryl trinitrate on remote ischemic conditioning. AB - Remote ischemic conditioning (RIC) protects against sustained myocardial ischemia. Because of overlapping mechanisms, this protection may be altered by glyceryl trinitrate (GTN), which is commonly used in the treatment of patients with chronic ischemic heart disease. We investigated whether long-term GTN treatment modifies the protection by RIC in the rat myocardium and human endothelium. We studied infarct size (IS) in rat hearts subjected to global ischemia-reperfusion (I/R) in vitro and endothelial function in healthy volunteers subjected to I/R of the upper arm. In addition to allocated treatment, rats were coadministered with reactive oxygen species (ROS) or nitric oxide (NO) scavengers. Rats and humans were randomized to 1) control, 2) RIC, 3) GTN, and 4) GTN + RIC. In protocols 3 and 4, rats and humans underwent long-term GTN treatment for 7 consecutive days, applied subcutaneously or 2 h daily transdermally. In rats, RIC and long-term GTN treatment reduced mean IS (18 +/- 12%, P = 0.007 and 15 +/- 5%, P = 0.002) compared with control (35 +/- 13%). RIC and long-term GTN treatment in combination did not reduce IS (29 +/- 12%, P = 0.55 vs. control). ROS and NO scavengers both attenuated IS reduction by RIC and long-term GTN treatment. In humans, I/R reduced endothelial function ( P = 0.01 vs. baseline). Separately, RIC and long-term GTN prevented the reduction in endothelial function caused by I/R; given in combination, prevention was lost. RIC and long-term GTN treatment both protect against rat myocardial and human endothelial I/R injury through ROS and NO-dependent mechanisms. However, when given in combination, RIC and long-term GTN treatment fail to confer protection. NEW & NOTEWORTHY Remote ischemic conditioning (RIC) and long-term glyceryl trinitrate (GTN) treatment protect against ischemia-reperfusion injury in both human endothelium and rat myocardium. However, combined application of RIC and long-term GTN treatment abolishes the individual protective effects of RIC and GTN treatment on ischemia-reperfusion injury, suggesting an interaction of clinical importance. PMID- 29569955 TI - Placental growth factor reverses decreased vascular and uteroplacental MMP-2 and MMP-9 and increased MMP-1 and MMP-7 and collagen types I and IV in hypertensive pregnancy. AB - Preeclampsia is a complication of pregnancy manifested as maternal hypertension (HTN) and fetal intrauterine growth restriction, with unclear mechanisms. Placental ischemia increases antiangiogenic soluble fms-like tyrosine kinase-1 (sFlt-1) relative to angiogenic placental growth factor (PlGF); however, the molecular targets are unclear. To test the hypothesis that placental ischemia induced changes in sFlt-1 and PlGF target vascular and uteroplacental matrix metalloproteinases (MMPs), we tested whether raising the sFlt-1-to-PlGF ratio by infusing sFlt-1 (10 ug.kg-1.day-1) in pregnant (Preg) rats increases blood pressure (BP) and alters MMPs and whether correcting sFlt-1/PlGF by infusing PlGF (20 ug.kg-1.day-1) in Preg rats with reduced uterine perfusion pressure (RUPP) improves BP and reverses the changes in MMPs. On gestational day 19, BP was higher and the litter size and uterine, placenta, and pup weight were less in Preg + sFlt-1 and RUPP than Preg rats and restored in RUPP + PlGF versus RUPP rats. Gelatin and casein zymography and Western blots revealed decreases in MMP-2 and MMP-9 and increases in MMP-1 and MMP-7 in the aorta, uterine artery, uterus, and placenta of Preg + sFlt-1 and RUPP versus Preg rats, which were reversed in RUPP + PlGF versus RUPP rats. Collagen types I and IV were more abundant in Preg + sFlt-1 and RUPP versus Preg rats and were reversed in RUPP + PlGF versus RUPP rats. Thus, PlGF reverses decreased vascular and uteroplacental MMP-2 and MMP-9 and increased MMP-1, MMP-7, and collagen types I and IV induced by placental ischemia and sFlt-1 in HTN in pregnancy. Angiogenic factors and MMP modulators could rectify changes in MMPs and collagen, restore vascular and uteroplacental remodeling, and improve HTN and intrauterine growth restriction in preeclampsia. NEW & NOTEWORTHY Understanding the mechanisms of preeclampsia could help in its prevention and management. This study shows that correcting soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) imbalance by infusing PlGF reverses the decreases in vascular and uteroplacental matrix metalloproteinase (MMP)-2 and MMP-9 and the increases in MMP-1, MMP-7, and collagen types I and IV induced by placental ischemia and antiangiogenic sFlt-1 in hypertension in pregnancy. Angiogenic factors and MMP modulators could rectify changes in vascular and uteroplacental MMPs and collagen content and ameliorate hypertension and intrauterine growth restriction in preeclampsia. PMID- 29569959 TI - Noninvasive assessment of the common carotid artery hemodynamics with increasing exercise work rate using wave intensity analysis. AB - Noninvasively determined local wave speed ( c) and wave intensity (WI) parameters provide insights into arterial stiffness and cardiac-vascular interactions in response to physiological perturbations. However, the effects of incremental exercise and subsequent recovery on c and WI have not been fully established. We examined the changes in c and WI parameters in the common carotid artery (CCA) during exercise and recovery in eight young, healthy male athletes. Ultrasound measurements of CCA diameter and blood flow velocity were acquired at rest, during five stages of incremental exercise (up to 70% maximum work rate), and throughout 1 h of recovery, and noninvasive WI analysis [diameter-velocity ( DU) approach] was performed. During exercise, c increased (+136%), showing increased stiffness with work rate. All peak and area of forward compression, backward compression, and forward expansion waves increased during exercise (+452%, +700%, and +900%, respectively). However, WI reflection indexes and CCA resistance did not significantly change from rest to exercise. Furthermore, wave speed and the magnitude of all waves returned to baseline within 5 min of recovery, suggesting that the effects of exercise in the investigated parameters of young, healthy individuals were transient. In conclusion, incremental exercise was associated with an increase in local CCA stiffness and increases in all wave parameters, indicative of enhanced ventricular contractility and improved late-systolic blood flow deceleration. NEW & NOTEWORTHY We examined hemodynamics of the common carotid artery using noninvasive application of wave intensity analysis during exercise and recovery. The hemodynamic adjustments to exercise were associated with increases in local common carotid artery stiffness and all waves' parameters, with the latter indicating enhanced ventricular contractility and improved late systolic blood flow deceleration. PMID- 29569960 TI - Is there a superior simulator for human anatomy education? How virtual dissection can overcome the anatomic and pedagogic limitations of cadaveric dissection. AB - Educators must select the best tools to teach anatomy to future physicians and traditionally, cadavers have always been considered the "gold standard" simulator for living anatomy. However, new advances in technology and radiology have created new teaching tools, such as virtual dissection, which provide students with new learning opportunities. Virtual dissection is a novel way of studying human anatomy through patient computed tomography (CT) scans. Through touchscreen technology, students can work together in groups to "virtually dissect" the CT scans to better understand complex anatomic relationships. This article presents the anatomic and pedagogic limitations of cadaveric dissection and explains what virtual dissection is and how this new technology may be used to overcome these limitations.

PMID- 29569962 TI - A novel uromodulin mutation in autosomal dominant tubulointerstitial kidney disease: a pedigree-based study and literature review. AB - Autosomal dominant tubulointerstitial kidney disease caused by mutations in uromodulin gene (ADTKD-UMOD) is a spectrum of hereditary renal disorders, characterized by early-onset hyperuricemia, gout and progressive nephropathy. This study presented a novel UMOD mutation in an ADTKD pedigree and reviewed studies in Chinese population. The index patient is a 16-year-old girl with hypertension, hyperuricemia and normal serum creatinine level. Four affected and six unaffected members were available for genetic screen. The mutation analysis was performed by next-generation sequencing and direct sequencing. A literature research was conducted to review Chinese ADTKD-UMOD cases. MEDLINE and Chinese Biomedicine Databases were searched with 'uromodulin', 'juvenile gout' and their related terms. Genetic sequencing revealed a de novo mutation within exon 3 (Cys223Gly), which was co-segregating with phenotype in this pedigree. In the review, four studies and our study involving a total of 67 ADTKD patients from 11 families were identified. Of these patients, 27 were confirmed to carry UMOD mutations. Mutations occurred in exon 3 were commonly observed, while mutations within exon 4, 5 and 9 occurred less frequently in Chinese ADTKD-UMOD cases. Among these cases, median age of symptom onset was 26.5 years, median age of end stage renal diseases (ESRD) or death by ESRD was 41.9 years without renal replacement treatment. Phenotype caused by mutations in D8C domain seemed to be severe than those in GPI domain. Compared with patients of other race, Chinese ADTKD-UMOD patients advanced more aggressively to ESRD. PMID- 29569963 TI - Analysis of alterations in white matter integrity of adult patients with comitant exotropia. AB - Objective This study was performed to investigate structural abnormalities of the white matter in patients with comitant exotropia using the tract-based spatial statistics (TBSS) method. Methods Diffusion tensor imaging data from magnetic resonance images of the brain were collected from 20 patients with comitant exotropia and 20 age- and sex-matched healthy controls. The FMRIB Software Library was used to compute the diffusion measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD). These measures were obtained using voxel-wise statistics with threshold-free cluster enhancement. Results The FA values in the right inferior fronto-occipital fasciculus (IFO) and right inferior longitudinal fasciculus were significantly higher and the RD values in the bilateral IFO, forceps minor, left anterior corona radiata, and left anterior thalamic radiation were significantly lower in the comitant exotropia group than in the healthy controls. No significant differences in the MD or AD values were found between the two groups. Conclusions Alterations in FA and RD values may indicate the underlying neuropathologic mechanism of comitant exotropia. The TBSS method can be a useful tool to investigate neuronal tract participation in patients with this disease. PMID- 29569965 TI - Analysis of risk factors for cervical lymph node metastases in patients with sporadic medullary thyroid carcinoma. AB - Objective Medullary thyroid carcinoma (MTC) is classified as either sporadic or inherited. This study was performed to analyze the risk factors for cervical lymph node metastases and predict the indication for prophylactic lateral neck dissection in patients with sporadic MTC. Methods Sixty-five patients with sporadic MTC were retrospectively reviewed. Univariate analysis with the chi square test and multiple logistic regression analysis were applied to identify the clinicopathological features (sex, age, tumor size, number of tumor foci, capsule or vascular invasion, and others) associated with cervical lymph node metastases. Results The metastasis rates in the central and lateral compartments were 46.2% (30/65) and 40.0% (26/65), respectively. The incidence of cervical lymph node metastases was significantly higher in patients with a tumor size of >1 cm, tumor multifocality, and thyroid capsule invasion. Only thyroid capsule invasion was an independent predictive factor for central compartment metastases and lateral neck metastases. The possibility of central compartment metastases was significantly higher when the preoperative serum carcinoembryonic antigen concentration was >30 ng/mL (60.0% vs. 34.3%). Conclusions MTC is associated with a high incidence of cervical lymph node metastases. Prophylactic lateral node dissection is necessary in patients with thyroid capsule invasion or a high serum carcinoembryonic antigen concentration.

PMID- 29569964 TI - Zanthoxylum alatum abrogates lipopolysaccharide-induced depression-like behaviours in mice by modulating neuroinflammation and monoamine neurotransmitters in the hippocampus. AB - CONTEXT: Depression is an inflammatory, commonly occurring and lethal psychiatric disorder having high lifetime prevalence. Zanthoxylum alatum Roxb. (Rutaceae), commonly called Timur, has high medicinal value and is used ethnomedicinally for the treatment of various diseases. OBJECTIVE: To evaluate the effect of hexane extract of Z. alatum seeds (ZAHE) on lipopolysaccharide (LPS)-induced depression like behaviour in Swiss albino mice. MATERIALS AND METHODS: Mice were treated with ZAHE (100 and 200 mg/kg, p.o.) and imipramine (10 mg/kg injected i.p.) for 14 days. On 14th day of the treatment, depression-like behaviour was induced by LPS (0.83 mg/kg injected i.p.) and after 24 h of LPS administration, it was assessed by measuring behavioural parameters and biochemical estimations. RESULTS: Behavioural tests, including the open field test, forced swimming test, tail suspension test and sucrose preference test revealed that ZAHE (100 and 200 mg/kg, p.o.) and imipramine (10 mg/kg injected i.p.) alleviated the depression symptoms of LPS-induced mice. Moreover, ZAHE treatments reversed the LPS-induced alterations in the concentrations of norepinephrine and serotonin (5-HT) and inhibited the expression of brain-derived neurotrophic factor, pro-inflammatory cytokines and oxido-nitrosative stress in the mice. Acute toxicity was calculated to be LD50 > 2500 mg/kg. DISCUSSION AND CONCLUSIONS: This study showed that LPS induced depression in mice was significantly prevented by ZAHE at both the dosages. In conclusion, ZAHE exhibited an antidepressant activity by altering monoaminergic neurotransmitters in the brain combined with its anti-inflammatory potential. Thus, it could be an effective therapeutic against inflammation induced depression and other brain disorders. PMID- 29569967 TI - Characteristics of adults who stutter by treatments sought. AB - Several treatment approaches are available for adults who stutter, including speech treatment, cognitive behaviour therapy (CBT) treatment for anxiety, and a combination of both. It is useful to determine whether any differences exist between adults who stutter enrolled in different types of treatment. Therefore, the purpose of this study was to compare demographic, speech, and psychological characteristics of adults who stutter enrolled in speech, psychological, and combined treatment programs. Participants were 288 adults who stuttered (18-80 years) enrolled in one of three different treatment programs: Speech Treatment for stuttering (n = 134), Anxiety Treatment for anxiety about stuttering (n = 70), or Speech Treatment for Stuttering With or Without Anxiety Treatment (n = 84). Participants completed a range of demographic, speech, and psychological measures prior to the start of treatment. A significantly higher proportion of participants in the Anxiety Treatment group were in a personal relationship than the other treatment groups. The Anxiety Treatment group had higher average age than the other treatment groups. The Speech Treatment group also demonstrated significantly higher self-rated stuttering severity than the Anxiety Treatment group, even though there were no significant difference between groups for clinician-rated percentage of syllables stuttered. Although most characteristics of adults who stuttered did not vary by treatment type, the present findings suggest that adults who stutter enrolled in speech treatment perceived their stuttering as more severe, which may have prompted treatment seeking. Further research is needed regarding the supportive influence of personal relationship for those with the disorder. PMID- 29569969 TI - Implementation of team-based learning on a large scale: Three factors to keep in mind. AB - Team-based learning (TBL) is a structured form of small group learning that can be scaled up for delivery in large classes. The principles of successful TBL implementation are well established. TBL has become widely practiced in medical schools, but its use is typically limited to certain courses or parts of courses. Implementing TBL on a large scale, across different courses and disciplines, is the next logical step. The Lee Kong Chian School of Medicine (LKCMedicine), a partnership between Nanyang Technological University, Singapore and Imperial College London, admitted its first students in 2013. This new undergraduate medical program, developed collaboratively by faculty at both institutions, uses TBL as its main learning and teaching strategy, replacing all face-to-face lectures. TBL accounts for over 60% of the curriculum in the first two years, and there is continued learning through TBL during campus teaching in the remaining years. This paper describes our experience of rolling out TBL across all years of the medical curriculum, focusing on three success factors: (1) "team-centric" learning spaces, to foster active, collaborative learning; (2) an e-learning ecosystem, seamlessly integrated to support all phases of the TBL process and (3) teaching teams in which experts in pedagogical process (TBL Facilitators) co teach with experts in subject matter (Content Experts). PMID- 29569968 TI - Organizational Health Literacy: Review of Theories, Frameworks, Guides, and Implementation Issues. AB - Organizational health literacy is described as an organization-wide effort to transform organization and delivery of care and services to make it easier for people to navigate, understand, and use information and services to take care of their health. Several health literacy guides have been developed to assist healthcare organizations with this effort, but their content has not been systematically reviewed to understand the scope and practical implications of this transformation. The objective of this study was to review (1) theories and frameworks that inform the concept of organizational health literacy, (2) the attributes of organizational health literacy as described in the guides, (3) the evidence for the effectiveness of the guides, and (4) the barriers and facilitators to implementing organizational health literacy. Drawing on a metanarrative review method, 48 publications were reviewed, of which 15 dealt with the theories and operational frameworks, 20 presented health literacy guides, and 13 addressed guided implementation of organizational health literacy. Seven theories and 9 operational frameworks have been identified. Six health literacy dimensions and 9 quality-improvement characteristics were reviewed for each health literacy guide. Evidence about the effectiveness of health literacy guides is limited at this time, but experiences with the guides were positive. Thirteen key barriers (conceived also as facilitators) were identified. Further development of organizational health literacy requires a strong and a clear connection between its vision and operationalization as an implementation strategy to patient-centered care. For many organizations, becoming health literate will require multiple, simultaneous, and radical changes. Organizational health literacy has to make sense from clinical and financial perspectives in order for organizations to embark on such transformative journey. PMID- 29569970 TI - Spinal dura mater: biophysical characteristics relevant to medical device development. AB - Understanding the relevant biophysical properties of the spinal dura mater is essential to the design of medical devices that will directly interact with this membrane or influence the contents of the intradural space. We searched the literature and reviewed the pertinent characteristics for the design, construction, testing, and imaging of novel devices intended to perforate, integrate, adhere or reside within or outside of the spinal dura mater. The spinal dura mater is a thin tubular membrane composed of collagen and elastin fibres that varies in circumference along its length. Its mechanical properties have been well-described, with the longitudinal tensile strength exceeding the transverse strength. Data on the bioelectric, biomagnetic, optical and thermal characteristics of the spinal dura are limited and sometimes taken to be similar to those of water. While various modalities are available to visualise the spinal dura, magnetic resonance remains the best modality to segment its structure. The reaction of the spinal dura to imposition of a foreign body or other manipulations of it may compromise its biomechanical and immune-protective benefits. Therefore, dural sealants and replacements are of particular clinical, research and commercial interest. In conclusion, existing devices that are in clinical use for spinal cord stimulation, intrathecal access or intradural implantation largely adhere to traditional designs and their attendant limitations. However, if future devices are built with an understanding of the dura's properties incorporated more fully into the designs, there is potential for improved performance. PMID- 29569971 TI - Src family kinase inhibitor bosutinib enhances retinoic acid-induced differentiation of HL-60 leukemia cells. AB - The acute promyelocytic leukemia (APL) has been treated with all-trans retinoic acid (RA) for decades. While RA has largely been ineffective in non-APL AML subtypes, co-treatments combining RA and other agents are currently in clinical trials. Using the RA-responsive non-APL AML cell line HL-60, we tested the efficacy of the Src family kinase (SFK) inhibitor bosutinib on RA-induced differentiation. HL-60 has been recently shown to bear fidelity to a subtype of AML that respond to RA. We found that co-treatment with RA and bosutinib enhanced differentiation evidenced by increased CD11b expression, G1/G0 cell cycle arrest, and respiratory burst. Expression of the SFK members Fgr and Lyn was enhanced, while SFK activation was inhibited. Phosphorylation of several sites of c-Raf was increased and expression of AhR and p85 PI3K was enhanced. Expression of c-Cbl and mTOR was decreased. Our study suggests that SFK inhibition enhances RA induced differentiation and may have therapeutic value in non-APL AML. PMID- 29569972 TI - Expression of TRIM28 correlates with proliferation and Bortezomib-induced apoptosis in B-cell non-Hodgkin lymphoma. AB - Tripartite motif containing 28 (TRIM28) as a transcriptional co-repressor has been reported playing a role in regulating DNA damage response (DDR), cell differentiation, immune response, and tumorigenesis. The present study was performed to explore the biological function and clinical significance of TRIM28 in B-cell non-Hodgkin lymphoma (B-NHL). Results of the study displayed that high expression of TRIM28 was positively associated with the poorer survival of B-NHL patients as an independent prognostic factor. In addition, TRIM28 could promote the B-NHL cells proliferation through modulating cell cycle progression. The change of cyclinA, P21, and PCNA expression after TRIM28 expression modified further illustrated the mechanism in which TRIM28 participated in cell proliferation progression. Moreover, inhibition TRIM28 expression in B-NHL cells enhanced the sensibility to Bortezomib by regulating p53-mediated apoptosis pathway. Taken together, the present study showed that TRIM28 functions as a tumor promoter in B-NHL and may be a novel target for drug resistance to Bortezomib. PMID- 29569973 TI - Black Raspberry Extract Enhances LDL Uptake in HepG2 Cells by Suppressing PCSK9 Expression to Upregulate LDLR Expression. AB - Black raspberry extract (BRE) has been widely used for treating prostate and urinary diseases and hyperlipidemia in Asia due to its significant lipid-lowering effects. The aim of this investigation was to evaluate the antihypercholesterolemia activity of BRE and the potential molecular mechanisms responsible for its antihypercholesterolemia activity by regulation of proprotein convertase subtilisin/kexin type 9 (PCSK9) expression in the human liver cell line HepG2. Reporter-based functional assay was used to identify herbal extracts that suppress PCSK9 expression in the HepG2 cells. Quantitative real-time polymerase chain reaction, Western blot analysis, and immunofluorescence staining were used to evaluate whether BRE modulates low-density lipoprotein receptor (LDLR) expression by repressing the hepatic expression of PCSK9. The LDLR activity of the HepG2 cells was determined using an LDL uptake assay. Our finding revealed that BRE modulates LDLR expression by suppressing the hepatic expression of PCSK9. We found that the combination of simvastatin and BRE caused the synergic induction of LDLR expression and LDL-C uptake, whereas simvastatin alone increased the expression of PCSK9 in the HepG2 cells. These results clearly demonstrated that the BRE from black raspberry suppressed simvastatin-induced PCSK9 expression and improved LDL-C uptake by hepatocytes through the induction of LDLR expression. These results suggest that the suppression of PCSK9 expression by BRE may potentiate the hypolipidemic effect of statins.

AB - Objective To use a mathematical model to simulate an influenza outbreak in a school in order to assess the effectiveness of isolation (Iso), antiviral therapeutics, antiviral prophylactics (P), vaccination prior to the outbreak, and school closure (for 1 [S1w], 2 or 3 weeks). Methods This study developed a susceptible-exposed-infectious/asymptomatic-recovered model to estimate the effectiveness of commonly used interventions for seasonal influenza outbreaks in school. Results The most effective single-intervention strategy was isolation with a total attack rate of 1.99% and an outbreak duration of 30 days. The additional effectiveness of antiviral therapeutics and prophylactics and vaccination (prior to the outbreak) strategies were not obvious. Although Iso+P, P+Iso+S1w, four-, and five-combined intervention strategies had commendable effectiveness, total attack rate decreased only slightly, and outbreak duration was shortened by 9 days maximum, compared with the single-intervention isolation strategy. School closure for 1, 2 or 3 weeks was futile or even counterproductive. Conclusion Isolation, as a single intervention, was the most effective in terms of reducing the total attack rate and the duration of the outbreak. PMID- 29569976 TI - Polyphenol-Rich Blackcurrant Juice Prevents Endothelial Dysfunction in the Mesenteric Artery of Cirrhotic Rats with Portal Hypertension: Role of Oxidative Stress and the Angiotensin System. AB - Chronic liver diseases with portal hypertension are characterized by a progressive vasodilatation, endothelial dysfunction, and NADPH oxidase-derived vascular oxidative stress, which have been suggested to involve the angiotensin system. This study evaluated the possibility that oral intake of polyphenol-rich blackcurrant juice (PRBJ), a rich natural source of antioxidants, prevents endothelial dysfunction in a rat model of cirrhosis induced by chronic bile duct ligation (CBDL), and, if so, determined the underlying mechanism. Male Wistar rats received either control drinking water or water containing 60 mg/kg gallic acid equivalents of PRBJ for 3 weeks before undergoing surgery with CBDL or sham surgery. After 4 weeks, vascular reactivity was assessed in mesenteric artery rings using organ chambers. Both the acetylcholine-induced nitric oxide (NO)- and endothelium-dependent hyperpolarization (EDH)-mediated relaxations in mesenteric artery rings were significantly reduced in CBDL rats compared to sham rats. An increased level of oxidative stress and expression of NADPH oxidase subunits, COX 2, NOS, and of the vascular angiotensin system are observed in arterial sections in the CBDL group. Chronic intake of PRBJ prevented the CBDL-induced impaired EDH mediated relaxation, oxidative stress, and expression of the different target proteins in the arterial wall. In addition, PRBJ prevented the CBDL-induced increase in the plasma level of proinflammatory cytokines (interleukin [IL] 1alpha, monocyte chemotactic protein 1, and tumor necrosis factor alpha) and the decrease of the anti-inflammatory cytokine, IL-4. Altogether, these observations indicate that regular ingestion of PRBJ prevents the CBDL-induced endothelial dysfunction in the mesenteric artery most likely by normalizing the level of vascular oxidative stress and the angiotensin system. PMID- 29569978 TI - Anticipatory guidance in type 2 diabetes to improve disease management; next steps after basal insulin. AB - The alarming rise in the number of people living with type 2 diabetes (T2D) presents primary care physicians with increasing challenges associated with long term chronic disease care. Studies have shown that the majority of patients are not achieving or maintaining glycemic goals, putting them at risk of a wide range of diabetes-related complications. Disease- and self-management programs have been shown to help patients improve their glycemic control, and are likely to be of particular benefit for patients with diabetes dealing with these issues. Anticipatory guidance is an individualized, proactive approach to patient education and counseling by a health-care professional to support patients in better coping with problems before they arise. It has been shown to improve disease outcomes in a variety of chronic conditions, including diabetes. While important at all stages, anticipatory guidance may be of particular importance during changes in treatment regimens, and especially during transition to, and escalation of, insulin-based regimens. The aim of this article is to provide advice to physicians on anticipatory guidance for basal-insulin dosing, focusing on appropriate basal-insulin-dose increase and prevention of potentially deleterious basal-insulin doses, so called overbasalization. It also provides an overview of new treatment options for patients with T2D who are not well controlled on basal-insulin therapy, fixed-ratio combinations of basal insulin and glucagon-like peptide-1 receptor agonists, and advice on the type of anticipatory guidance needed to ensure safe and appropriate switching to these therapies.

PMID- 29569981 TI - Regulatory T-cells within bone marrow-derived stem cells actively confer immunomodulatory and neuroprotective effects against stroke. AB - Regulatory T-cells (Tregs) may exert a neuroprotective effect on ischemic stroke by inhibiting both inflammation and effector T-cell activation. Transplantation of human bone marrow-derived stem cells (BMSCs) in ischemic stroke affords neuroprotection that results in part from the cells' anti-inflammatory property. However, the relationship between Tregs and BMSCs in treatment of ischemic stroke has not been fully elucidated. Here, we tested the hypothesis that Tregs within the BMSCs represent active mediators of immunomodulation and neuroprotection in experimental stroke. Primary rat neuronal cells were subjected to an oxygen glucose deprivation and reperfusion (OGD/R) condition. The cells were re-perfused and co-cultured with Tregs and/or BMSCs. We detected a minority population of Tregs within BMSCs with both immunocytochemistry (ICC) and flow cytometry identifying cells expressing phenotypic markers of CD4, CD25, and FoxP3 protein. BMSCs with the native population of Tregs conferred maximal neuroprotection compared to the treatment conditions containing 0%, 10%, and 100% relative ratio Tregs. Increasing the Treg population resulted in increased IL6 secretion and decreased FGF-beta secretion by BMSCs. This study shows that a minority population of Tregs exists within the therapeutic BMSC population, which serves as robust mediators of the immunomodulatory and neuroprotective effect provided by BMSC transplantation. PMID- 29569980 TI - Synergistic action of inflammation and lipid dysmetabolism on kidney damage in rats. AB - In kidney disease, inflammation and lipid dysmetabolism are often associated together, however, the effect and mechanism of inflammatory mediators and lipid dysmetabolism on kidney damage is still unclear. In this study, Wistar rats were randomized into four groups: normal diet + saline (Group N), high-fat diet (HF)+ saline (Group HF), normal diet + adriamycin (Group ADR), HF + adriamycin (Group ADR + HF). After 10 weeks of feeding, rats in each group were randomly sacrificed. We found that the protein content of urine in ADR and ADR + HF groups were significantly higher than that of group N and HF while the serum levels of total protein and albumin in the ADR and ADR + HF groups decreased correspondingly. The serum levels of triglyceride, total cholesterol and low density lipoprotein in the HF, ADR and ADR + HF groups increased. In the treatment groups, mesangial proliferation, matrix accumulation, tubular vacuolization, inflammatory cell infiltration and fat deposition were detected. These pathological changes were the most serious in the ADR + HF group. The expression of tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta1 (TGF-beta1) were increased in each treatment group, especially in the ADR + HF group. Our results suggested that the inflammatory factors and abnormal lipid levels can activate the inflammatory response in kidney of the Wistar rats, and lead to a series of pathological changes in renal tissue, and inflammatory factors and lipid dysmetabolism can aggravate damage in the kidney. PMID- 29569982 TI - Quercetin Reduces Tumor Necrosis Factor Alpha-Induced Muscle Atrophy by Upregulation of Heme Oxygenase-1. AB - The inflammatory cytokine tumor necrosis factor alpha (TNFalpha), upregulated in the obese condition, promotes protein degradation and is implicated in obesity related skeletal muscle atrophy and age-related sarcopenia. Quercetin, a flavonoid, elicits antioxidative and anti-inflammatory activities. In this study, we investigated the effect of quercetin on TNFalpha-induced skeletal muscle atrophy as well as its potential mechanism of action. In this study, we observed that quercetin suppressed expression of TNFalpha-induced atrophic factors such as MAFbx/atrogin-1 and MuRF1 in myotubes, and it enhanced heme oxygenase-1 (HO-1) protein level accompanied by increased nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) in myotubes. The HO-1 inhibitor ZnPP suppressed the inhibitory actions of quercetin on TNFalpha-induced atrophic responses and degradation of IkappaB-alpha in myotubes. Moreover, quercetin supplementation to high-fat diet-fed obese mice inhibited obesity-induced atrophic responses in skeletal muscle, accompanied by upregulation of HO-1 and inactivation of nuclear factor-kappa B (NF-kappaB), and the quercetin actions were attenuated in Nrf2-deficient mice. These findings suggest that quercetin protects against TNFalpha-induced muscle atrophy under obese conditions through Nrf2-mediated HO-1 induction accompanied by inactivation of NF-kappaB. Quercetin may be used as a dietary supplement to protect against obesity-induced skeletal muscle atrophy.

AB - 12.6% of major depressive disorder (MDD) patients have suicide intent, while it has been reported that 43% of patients did not consult their doctors for MDD, automated MDD screening is eagerly anticipated. Recently, in order to achieve automated screening of MDD, biomarkers such as multiplex DNA methylation profiles or physiological method using near infra-red spectroscopy (NIRS) have been studied, however, they require inspection using 96-well DNA ELIZA kit after blood sampling or significant cost. Using a single-lead electrocardiography (ECG), we developed a high-precision MDD screening system using transient autonomic responses induced by dual mental tasks. We developed a novel high precision MDD screening system which is composed of a single-lead ECG monitor, analogue to digital (AD) converter and a personal computer with measurement and analysis program written by LabView programming language. The system discriminates MDD patients from normal subjects using heat rate variability (HRV)-derived transient autonomic responses induced by dual mental tasks, i.e. verbal fluency task and random number generation task, via linear discriminant analysis (LDA) adopting HRV-related predictor variables (hear rate (HR), high frequency (HF), low frequency (LF)/HF). The proposed system was tested for 12 MDD patients (32 +/- 15 years) under antidepressant treatment from Shizuoka Saiseikai General Hospital outpatient unit and 30 normal volunteers (37 +/- 17 years) from Tokyo Metropolitan University. The proposed system achieved 100% sensitivity and 100% specificity in classifying 42 examinees into 12 MDD patients and 30 normal subjects. The proposed system appears promising for future HRV-based high precision and low-cost screening of MDDs using only single-lead ECG.

AB - INTRODUCTION: Ovarian cancer (OC) is one of the leading causes of cancer-related death in women. Accumulating evidence showed an evolving role of HE4 in monitoring the progression and prognosis of OC but without a comprehensive analysis for prognosis and survival data. Areas covered: The present meta analysis aims to explore the association of HE4 with survival and the clinicopathological features of OC patients. PubMed, Embase, Web of Science and the China National Knowledge Infrastructure (CNKI) were searched for relevant studies regarding the role of both serum and tissue HE4 expression in ovarian cancer. Expert commentary: HE4 has been proposed as the most promising biomarker that may complement the CA125 expression and has been approved by the FDA in monitoring the follow-up and relapse of OC patients. Our results are in accordance with the most recent evidence suggesting its important role in the prognostic surveillance of OC and a better performance in the early prediction of OC recurrence than CA125. PMID- 29569985 TI - Predictive risk factors of failed laryngeal mask airway insertion at first attempt. AB - Objectives A failed first attempt at laryngeal mask airway (LMA) insertion could increase the risk of laryngospasm, hypoxemia, and postoperative sore throat. This study was performed to investigate the risk factors for failed first-attempt LMA placement. Methods In total, 461 patients who underwent general anesthesia with a Supreme LMA (Teleflex Medical, Shanghai, China) and who had an American Society of Anesthesiologists (ASA) physical status of I to III were prospectively enrolled. The LMA was inserted after anesthetic induction. We recorded the insertion conditions and each patient's age, ASA status, body weight, body mass index (BMI), duration of anesthesia, size of LMA, and cuff pressure; the years of work experience of the anesthesiologists; and the use or nonuse of lidocaine gel as a lubricant. Results Successful first-attempt placement of the Supreme LMA was achieved in 438 (95.10%) patients, while first-attempt placement failed in 23 (4.99%). Significant risk factors for failure of first-attempt LMA insertion included high age, high body weight, BMI of <20 kg/m2, and insertion without using lidocaine gel. Conclusions A patient age of >61 years, high body weight, BMI of <20 kg/m2, and insertion without lidocaine gel could significantly increase the risk of failed first-attempt Supreme LMA insertion. PMID- 29569986 TI - Quantitative positron emission tomography reveals regional differences in aerobic glycolysis within the human brain. AB - Glucose and oxygen metabolism are tightly coupled in the human brain, with the preponderance of the brain's glucose supply used to generate ATP via oxidative phosphorylation. A fraction of glucose is consumed outside of oxidative phosphorylation despite the presence of sufficient oxygen to do so. We refer to this process as aerobic glycolysis. A recent positron emission tomography study reported that aerobic glycolysis is uniform within gray matter. Here, we analyze the same data and demonstrate robust regional differences in aerobic glycolysis within gray matter, a finding consistent with previously published data. PMID- 29569988 TI - A Healthy Beverage Consumption Pattern Is Inversely Associated with the Risk of Obesity and Metabolic Abnormalities in Korean Adults. AB - As the use of beverages in diets is increasing, several studies have examined the effect of beverage consumption in human health. Thus, we aimed at identifying specific beverage patterns and determining their associations with obesity and metabolic syndrome (MetS) risk factors in Korean adults. Based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2008-2012 data, 19,800 Korean adults (>=20 years) with a single 24-h dietary recall and health examination data were investigated. All beverage items consumed by participants were categorized into 15 beverage groups based on the KNHANES coding system. Three major beverage consumption patterns were identified according to factor analysis: (1) the "healthy beverage" (high intake of dairy products, 100% fruit/vegetable juices and low intake of alcoholic beverages); (2) the "sugar sweetened beverage" (high intake of soda, sweetened coffee/tea, and fruit drink); and (3) the "unsweetened beverage" (high intake of unsweetened coffee) patterns. Multivariable logistic regression analyses were conducted to determine the odds of obesity (body mass index >=25 kg/m2) and MetS (defined by National Cholesterol Education Program III [NCEP III]) for each beverage pattern after controlling for covariates. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for associations of the "healthy beverage" pattern with risks of obesity, abdominal obesity, and elevated triglycerides, fasting blood glucose (FBG), and blood pressure (BP) were 0.88 (0.79-0.98), 0.83 (0.74-0.92), 0.88 (0.78-0.99), 0.85 (0.79-0.98), and 0.81 (0.72-0.92), respectively. AORs (95% CIs) of associations of the "sugar-sweetened beverage" pattern with risks of abdominal obesity, elevated FBG and BP were 1.15 (1.03-1.30), 1.14 (1.01-1.29), and 1.18 (1.04 1.33), respectively. However, no associations were found between the "unsweetened beverage" pattern and any parameters examined. Intake of healthy beverages should be encouraged to reduce risks of obesity and metabolic abnormalities; however, individuals who consume sugar-sweetened beverages should be advised on the adverse effects of those beverages on the risk of obesity and MetS. PMID- 29569987 TI - Inhibitory effects of CP on the growth of human gastric adenocarcinoma BGC-823 tumours in nude mice. AB - Objective To investigate the potential antitumour effects of [2-(6-amino-purine-9 yl)-1-hydroxy-phosphine acyl ethyl] phosphonic acid (CP) against gastric adenocarcinoma. Methods Human BGC-823 xenotransplants were established in nude mice. Animals were randomly divided into control and CP groups, which were administered NaHCO3 vehicle alone or CP dissolved in NaHCO3 (200 ug/kg body weight) daily, respectively. Tumour volume was measured weekly for 6 weeks. Resected tumours were assayed for proliferative activity with anti-Ki-67 or anti proliferating cell nuclear antigen (PCNA) antibodies. Cell apoptosis was examined using terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) assays and with caspase-3 immunostaining. Proteins were measured by Western blotting. Results There was a significant reduction in tumour volume and a reduced percentage of Ki-67-positive or PCNA-positive cells in the CP group compared with the control group. The percentage of TUNEL-positive or caspase 3 positive cells significantly increased following CP treatment compared with the control group. Tumours from the CP group had higher levels of phosphorylated extracellular signal-regulated kinase (p-ERK) and phosphorylated-AKT (p-AKT) compared with control tumours. Conclusion CP treatment inhibited tumour growth and induced tumour cell apoptosis in a nude mouse model of BGC-823 gastric adenocarcinoma. Activation of the AKT and ERK signalling pathways may mediate this antitumour activity. PMID- 29569989 TI - Eyes to see and ears to hear: sensitivity in research on attachment and culture. AB - How and why should attachment researchers engage in research on attachment and culture? How should they strive to develop a theoretical perspective that is both contextually sensitive and also reflecting species-typical processes of evolutionary adaptation? These comments on the remarkable empirical papers of this special issue consider what is learned from these studies, what more is needed, and directions for future research. PMID- 29569991 TI - Examining Perceived Stress, Childhood Trauma and Interpersonal Trauma in Individuals With Drug Addiction. AB - The investigation of psychosocial factors in relation to opiate addiction is limited and typically uses binary measures to assess how incidences of childhood trauma correlate with addiction. There has also been a lack of enquiry into how experiences of noninterpersonal versus interpersonal trauma may impact drug use addiction. In this regard, the current study utilized a novel measurement of interpersonal versus noninterpersonal lifetime trauma and a scale assessing severity of childhood trauma to examine how these factors may impact patients with opioid addiction. The interaction between these factors and current perceived stress was also examined. Thirty-six opioid-dependent individuals (recruited from the Drug Health Services and Opioid Treatment Program at the Royal Prince Alfred Hospital in Sydney, Australia) and 33 healthy controls completed the Childhood Maltreatment Questionnaire, Lifetime Trauma Survey, and Perceived Levels of Stress Scale. The patient group reported significantly greater childhood trauma severity, more incidences of lifetime trauma, and higher perceived stress than controls. Logistic regression analyses indicated that the severity of childhood trauma was more strongly associated with addiction status than perceived stress. A greater number of lifetime trauma incidence was the best predictor of addiction. Contrary to expectations, noninterpersonal lifetime trauma was a better predictor of addiction status than was interpersonal lifetime trauma. Results suggest that lifetime trauma and childhood trauma may play an important factor in opioid addiction over what can be accounted for by stress. PMID- 29569990 TI - Molecular neuroimaging in primary progressive aphasia with predominant agraphia. AB - A 62-year-old male presented with progressive isolated writing and spelling difficulties. Neurological, neuropsychological, speech, and language evaluations identified only minimal additional abnormalities. The presenting characteristics did not meet criteria for any particular variant of primary progressive aphasia; his clinical presentation is best described as primary progressive aphasia, with a predominant, almost pure agraphia. Brain MRI showed asymmetric, bilateral parenchymal volume loss, with left hippocampal atrophy. Fluorodeoxyglucose-F18 positron emission tomography showed hypometabolism in the lateral left frontal lobe, including Exner's area. Beta-amyloid and tau-positron emission tomography scans were negative, indicating the etiology was not Alzheimer's disease. The underlying neurodegenerative process is most likely related to TDP-43, although a 4-repeat tauopathy cannot be excluded. Following his clinical evolution, and ultimately identifying the underlying pathology from autopsy, will elucidate the etiology of this interesting clinical presentation. PMID- 29569992 TI - Revisiting Factors Associated With Screen Time Media Use: A Structural Study Among School-Aged Adolescents. AB - BACKGROUND: Screen-based media overuse has been related to harmful consequences especially among children and adolescents. Given their complex interrelationships, predictors of screen time (ST) should be analyzed simultaneously rather than individually to avoid incomplete conclusions. METHODS: Structural equation models were conducted to examine associations between media ST (television, video games, and computers) along with harmful consequences in adolescents' well-being, such as underweight and overweight, depression, and school failure. Predictors included individual (gender, age, and physical activity), family (structure and socioeconomic background), and substance use variables. We used the Health Behaviour in School-aged Children survey organized in 2014, including eighth- and ninth-grade students living in France (N = 3720). RESULTS: Students reported spending 3 hours per day in front of each media. Spending more than 2 hours behind each of those 3 media was associated with lower life satisfaction, less physical activity, active school bullying, and grade repetition. Socioeconomic status was the most important predictor of ST, whereas regular substance uses showed modest associations. CONCLUSION: The main implication of our findings is to sensitize parents and stakeholders about the limitation of ST, including their own use that adolescents are likely to mimic. Alternative measures such as off-line time should be encouraged. PMID- 29569993 TI - Deaths after feeding-tube withdrawal from patients in vegetative and minimally conscious states: A qualitative study of family experience. AB - BACKGROUND: Families of patients in vegetative or minimally conscious states are often horrified by the suggestion of withdrawing a feeding tube, even when they believe that their relative would not have wanted to be maintained in their current condition. Very little is known about what it is like to witness such a death. AIM: To understand these families' experience of their relatives' deaths. DESIGN: Qualitative study using in-depth narrative interviews analyzed inductively with thematic analysis. PARTICIPANTS: A total of 21 people (from 12 families) whose vegetative or minimally conscious relative died following court authorized withdrawal of artificial nutrition and hydration. All had supported treatment withdrawal. FINDINGS: Interviewees were usually anxious in advance about the nature of the death and had sometimes confronted resistance from, and been provided with misinformation by, healthcare staff in long-term care settings. However, they overwhelmingly described deaths as peaceful and sometimes even as a "good death." There was (for some) a significant "burden of witness" associated with the length of time it took the person to die and/or distressing changes in their appearance. Most continued to voice ethical objections to the manner of death while considering it "the least worst" option in the circumstances. CONCLUSION: Staff need to be aware of the distinctive issues around care for this patient group and their families. It is important to challenge misinformation and initiate honest discussions about feeding-tube withdrawal and end-of-life care for these patients. Families (and staff) need better support in managing the "burden of witness" associated with these deaths. PMID- 29569994 TI - Video observations of maternal sensitivity in urban and rural Iran. AB - There is evidence that rural versus urban residence is a salient factor in predicting parenting practices. In what is most likely the very first video observation study of parenting ever to come out of Iran, mothers and their 18-60 month-old children were observed for 30 min of free interaction at their homes in urban (n = 11) and rural (n = 15) Iran. None of the mothers made any comments about being filmed, none expressed insecurities about what to do, and only four mothers looked at the camera more than once or twice. Compared to rural mothers, urban mothers showed significantly higher levels of verbal expression, warmth, and doing chores as an activity during the observations. However, this did not translate to significant group differences mothers in sensitivity, non interference, and general involvement with the child. The discussion focuses on different modalities of expressing sensitivity in urban versus rural mothers in Iran. PMID- 29569996 TI - Adults Engaged in Sports in Early Life Have Higher Bone Mass Than Their Inactive Peers. AB - PURPOSE: To analyze the relationship between engagement in sports in early life and bone variables among adults of both sexes. METHODS: The sample was composed of 225 men and women. Demographic data were collected, and dual-energy X-ray absorptiometry was used to assess bone mineral density, bone mineral content, and lean soft tissue. Sports participation in early life was assessed by an interview including childhood and adolescence. Consumption of tobacco and alcohol was also assessed by interview and the habitual physical activity level by a pedometer. RESULTS: Inactive men had bone mineral content around 11% lower than active men in childhood or adolescence, whereas for women, this difference represented around 14%. Active men had 74% less fat mass than inactive men in early life, and the difference was 67% for women. Early sports participation explained the differences in whole-body bone mineral content (16.8%, P-value = .005) and bone mineral density (8.8%, P-value = .015), as well as bone mineral density in lower limbs (18.9%, P-value = .001) among women. CONCLUSION: Adults engaged in sports in early life have higher bone mass than their inactive peers, especially women. PMID- 29569997 TI - Patterns of Physical Activity and Screen Time Among Brazilian Children. AB - OBJECTIVE: To investigate the patterns of physical activity (PA) and screen time among children and adolescents attended by the Brazilian National Health System. METHODS: This cross-sectional study was conducted in the city of Bauru, Sao Paulo, Brazil. The sample was composed of 270 children and adolescents attending 5 basic health care units. PA and screen time were assessed through a questionnaire. Economic status, sex, and body composition variables were used as covariates. RESULTS: Boys were more likely to be active when compared with girls (odds ratio = 2.56; 95% confidence interval, 1.43-4.58). Children and adolescents who accumulated less screen time were more likely to be in the most active group (odds ratio = 0.41; 95% confidence interval, 0.24-0.72). When comparing data year on year, we found that the level of PA has not changed significantly among children aged 7-10 years; however, at the age of 10, we noticed a significant reduction in PA scores, which kept decreasing until the age of 12. Regarding screen time, the situation was the opposite, with the amount of time spent in this behavior increasing over the years. CONCLUSION: Our results showed an association between low PA levels and high amount of screen time among children and adolescents, showing that is necessary to encourage an active lifestyle, decreasing time spent on television, computers, cell phones, and video games. PMID- 29569995 TI - Phosphorylation and interactions associated with the control of the Leishmania Poly-A Binding Protein 1 (PABP1) function during translation initiation. AB - The Poly-A Binding Protein (PABP) is a conserved eukaryotic polypeptide involved in many aspects of mRNA metabolism. During translation initiation, PABP interacts with the translation initiation complex eIF4F and enhances the translation of polyadenylated mRNAs. Schematically, most PABPs can be divided into an N-terminal RNA-binding region, a non-conserved linker segment and the C-terminal MLLE domain. In pathogenic Leishmania protozoans, three PABP homologues have been identified, with the first one (PABP1) targeted by phosphorylation and shown to co-immunoprecipitate with an eIF4F-like complex (EIF4E4/EIF4G3) implicated in translation initiation. Here, PABP1 phosphorylation was shown to be linked to logarithmic cell growth, reminiscent of EIF4E4 phosphorylation, and coincides with polysomal association. Phosphorylation targets multiple serine-proline (SP) or threonine-proline (TP) residues within the PABP1 linker region. This is an essential protein, but phosphorylation is not needed for its association with polysomes or cell viability. Mutations which do impair PABP1 polysomal association and are required for viability do not prevent phosphorylation, although further mutations lead to a presumed inactive protein largely lacking phosphorylated isoforms. Co-immunoprecipitation experiments were carried out to investigate PABP1 function further, identifying several novel protein partners and the EIF4E4/EIF4G3 complex, but no other eIF4F-like complex or subunit. A novel, direct interaction between PABP1 and EIF4E4 was also investigated and found to be mediated by the PABP1 MLLE binding to PABP Interacting Motifs (PAM2) within the EIF4E4 N-terminus. The results shown here are consistent with phosphorylation of PABP1 being part of a novel pathway controlling its function and possibly translation in Leishmania. PMID- 29569998 TI - The use of behavioural theories in end-of-life care research: A systematic review. AB - BACKGROUND: It is necessary to understand behaviours that contribute to improvement in the quality of end-of-life care; use of behavioural theories allows identification of factors underlying end-of-life care behaviour, but little is known about the extent to which, and in what manner, these theories are used in an end-of-life care research context. AIM: To assess the number of end-of life care studies that have used behavioural theories, which theories were used, to what extent main constructs were explored/measured and which behavioural outcomes were examined. DESIGN: We conducted a systematic review. The protocol was registered on PROSPERO (CRD42016036009). DATA SOURCES: The MEDLINE (PubMed), PsycINFO, EMBASE, Web of Science and CINAHL databases were searched from inception to June 2017. We included studies aimed at understanding or changing end-of-life care behaviours and that explicitly referred to individual behavioural theories. RESULTS: We screened 2231 records by title and abstract, retrieved 43 full-text articles and included 31 studies - 27 quantitative (of which four (quasi-)randomised controlled trials) and four qualitative - for data extraction. More than half used the Theory of Planned Behaviour (9), the Theory of Reasoned Action (4) or the Transtheoretical Model (8). In 9 of 31 studies, the theory was fully used, and 16 of the 31 studies focussed on behaviours in advance care planning. CONCLUSION: In end-of-life care research, the use of behavioural theories is limited. As many behaviours can determine the quality of care, their more extensive use may be warranted if we want to better understand and influence behaviours and improve end-of-life care. PMID- 29569999 TI - Independent Associations and Interactions of Perceived Neighborhood and Psychosocial Constructs on Adults' Physical Activity. AB - BACKGROUND: Neighborhood and psychosocial variables are related to physical activity (PA), yet interactions between these factors in predicting PA are infrequently studied. METHODS: This analysis examines the independent associations and interactions between self-reported neighborhood and psychosocial variables in relation to moderate to vigorous PA (MVPA) among adults from a US panel sample. RESULTS: In adjusted models, neighborhood social capital was positively associated with meeting MVPA guidelines. Fewer barriers, greater self efficacy, and greater autonomous motivation also corresponded with greater odds of meeting MVPA guidelines. An interaction between social capital and autonomous motivation showed that social capital was only associated with MVPA when autonomous motivation was high. Participants who reported both high autonomous motivation and high social capital were most likely to meet MVPA guidelines. CONCLUSIONS: Neighborhood social capital, barriers, self-efficacy, and autonomous motivation may be important correlates in promoting adults' PA. Future directions include using objective neighborhood and PA data in similar analyses and investigating associations of neighborhood and psychosocial variables with multiple PA activities. Intervention research to promote PA should also examine whether effects of interventions targeting psychosocial constructs are moderated by features of an individual's neighborhood or whether perceived social capital can be addressed in interventions in conjunction with psychosocial variables. PMID- 29570000 TI - Assessment of peanut allergen Ara h1 in processed foods using a SWCNTs-based nanobiosensor. AB - The goals of this research were to develop a rapid single-walled carbon nanotube (SWCNT)-based biosensor and to employ it to commercial food products for Ara h1 detection. The SWCNT-based biosensor was fabricated with SWCNTs immobilized with antibody (pAb) through hybridization of 1-pyrenebutanoic acid succinimidyl ester (1-PBASE) as a linker. The resistance difference (DeltaR) was calculated by measuring linear sweep voltammetry (LSV) using a potentiostat. Resistance values increased as the concentration of Ara h1 increased over the range of 1 to 105 ng/L. The specific binding of anti-Ara h1 pAb to antigen including Ara h1 was confirmed by both indirect ELISA kit and biosensor assay. The biosensor was exposed to extracts prepared from commercial processed food containing peanuts, or no peanuts, and could successfully distinguish the peanut containing foods. In addition, the application of present biosensor approach documented the precise detection of Ara h1 concentrations in commercially available peanut containing foods. PMID- 29570001 TI - Do Not Forget About Public Transportation: Analysis of the Association of Active Transportation to School Among Washington, DC Area Children With Parental Perceived Built Environment Measures. AB - BACKGROUND: Although the active transportation (AT) indicator received an F grade on the 2016 US Report Card on Physical Activity for Children and Youth, this AT assessment excluded public transportation. An objective of the Built Environment and Active Play Study was to assess youth AT, including public transportation, among Washington, DC area children in relation to parental perceptions of neighborhood built environment (BE) variables. METHODS: Questionnaires were mailed to 2000 parents of children aged 7-12 years. AT to school (ATS) was assessed with the question: "In an average school week, how many days does your child use each of the following ways to get to and from school? (a) Walk; (b) Bike; (c) Car; (d) Bus or Metro." Parental perceived BE data were obtained through questionnaire items, and logistic regression was conducted to determine if BE variables were associated with youth ATS. RESULTS: The sample included 144 children (50% female; average age 9.7 years; 56.3% white; 23.7% African American; 10.4% Asian American). Over 30% used ATS-public transportation 5 days per week, and nearly 13% used ATS-walking daily. Parental perceived BE variables significantly predicted youth ATS-walking and ATS-public transportation. CONCLUSIONS: ATS-public transportation is common among Washington, DC area youth, and parental perceptions of BE can significantly predict ATS. PMID- 29570002 TI - Accelerometry-Derived Physical Activity Correlations Between Parents and Their Fourth-Grade Child Are Specific to Time of Day and Activity Level. AB - BACKGROUND: The purpose of this study was to employ high-frequency accelerometry to explore parent-child physical activity (PA) relationships across a free-living sample. METHODS: We recorded 7 days of wrist-mounted accelerometry data from 168 dyads of elementary-aged children and their parents. Using a custom MATLAB program (Natick, MA), we summed child and parent accelerations over 1 and 60 seconds, respectively, and applied published cut points to determine the amount of time spent in moderate-vigorous PA (MVPA). Bivariate and partial correlations examined parent-child relationships between percentage of time spent in MVPA. RESULTS: Weak to moderate positive correlations were observed before school (r = .326, P < .001), after school (r = .176, P = .023), during the evening (r = .213, P = .006), and on weekends (r = .231, P = .003). Partial correlations controlling for parent-child MVPA revealed significant relationships during the school day (r = .185, P = .017), before school (r = .315, P < .001), and on weekends (r = .266, P = .001). In addition, parents of more active children were significantly more active than parents of less active children during the evening. CONCLUSIONS: These data suggest that there is some association between parent-child PA, especially before school and on weekends. Future interventions aiming to increase PA among adults and children must consider patterns of MVPA specific to children and parents and target them accordingly. PMID- 29570003 TI - Economic Evaluation of Global Endometrial Ablation Versus Inpatient and Outpatient Hysterectomy for Treatment of Abnormal Uterine Bleeding: US Commercial and Medicaid Payer Perspectives. AB - Every year, abnormal uterine bleeding (AUB) exacts a heavy toll on women's health and leads to high costs for the US health care system. The literature shows that endometrial ablation results in fewer complications, shorter recovery and lower costs than more commonly performed hysterectomy procedures. The objective of this study was to model clinical-economic outcomes, budget impact, and cost effectiveness of global endometrial ablation (GEA) versus outpatient hysterectomy (OPH) and inpatient hysterectomy (IPH) procedures. A decision tree, state transition (semi-Markov) economic model was developed to simulate 3 hypothetical cohorts of women who received surgical treatment for AUB (GEA, OPH, and IPH) over 1, 2, and 3 years to evaluate clinical and economic outcomes for GEA vs. OPH and GEA vs. IPH. Two versions of the model were created to reflect both commercial health care payer and US Medicaid perspectives, and analyses were conducted for both payer types. Total health care costs in the first year after GEA were substantially lower compared with those for IPH and OPH. Budget impact analysis results showed that increasing GEA utilization yields total annual cost savings of about $906,000 for a million-member commercial health plan and about $152,000 in cost savings for a typical-sized state Medicaid plan with 1.4 million members. Cost-effectiveness analysis results for both perspectives showed GEA as economically dominant (conferring greater benefit at lower cost) over both OPH and IPH in the 1-year commercial scenario. This study demonstrates that, for some patients, GEA may prove to be a safe, uterus-sparing, cost-effective alternative to OPH and IPH for the surgical treatment of AUB. PMID- 29570004 TI - Demographics and clinical characteristics of episodic hypothermia in multiple sclerosis. AB - BACKGROUND: Episodic hypothermia (EH) can occur in multiple sclerosis (MS). The putative mechanism is impairment of thermoregulation due to a presumed demyelinating hypothalamic lesion. OBJECTIVE: To describe a cohort of patients with MS, who developed EH. METHODS: Patients were identified through review of the Mayo Clinic electronic medical record (1996 to July 2015). Search terms were [multiple sclerosis] or [MS] within the diagnoses field and [hypothermia] within any field. We reviewed records for accuracy of diagnoses and abstracted relevant data. Magnetic resonance imaging (MRI) was reviewed for presence of hypothalamic lesions. RESULTS: Of 156 patients, 34 had concurrent MS and hypothermia. Thirty two (94%) had progressive disease at EH onset. Median MS duration was 19.9 years, and median expanded disability status scale (EDSS) was 8.0. Most patients presented with alterations in consciousness. Infection was suspected as the precipitating factor in 19 (56%), but clinically/laboratory supported in only 9 (28%). MRI lesions were evident within the hypothalamus in only 4 (14%). CONCLUSION: EH occurs predominantly in patients with advanced secondary progressive MS. The major manifestation is altered consciousness. Infection is often suspected as causal, but infrequently confirmed. Although commonly implicated, hypothalamic lesions were rarely evident on MRI and were absent in two post-mortem evaluations. PMID- 29570005 TI - Can a Lifestyle Intervention Increase Active Transportation in Women Aged 55-70 years? Secondary Outcomes From a Pilot Randomized Controlled Trial. AB - BACKGROUND: Physical activity confers many health benefits to older adults, and adopting activity into daily life routines may lead to better uptake. The purpose of this study was to test the effect of a lifestyle intervention to increase daily physical activity in older women through utilitarian walking and use of public transportation. METHODS: In total, 25 inactive women with mean age (SD) of 64.1 (4.6) years participated in this pilot randomized controlled trial [intervention (n = 13) and control (n = 12)]. Seven-day travel diaries (trips per week) and the International Physical Activity Questionnaire (minutes per week) were collected at baseline, 3, and 6 months. RESULTS: At 3 months, intervention participants reported 9 walking trips per week and 643.5 minutes per week of active transportation, whereas control participants reported 4 walking trips per week and 49.5 minutes per week of active transportation. Adjusting for baseline values, there were significant group differences favoring Everyday Activity Supports You for walking trips per week [4.6 (0.5 to 9.4); P = .04] and active transportation minutes per week [692.2 (36.1 to 1323.5); P = .05]. At 6 months, significant group differences were observed in walking trips per week [6.1 (1.9 to 11.4); P = .03] favoring the intervention (9 vs 2 trips per week). CONCLUSION: Given these promising findings, the next step is to test Everyday Activity Supports You model's effectiveness to promote physical activity in older women within a larger study. PMID- 29570006 TI - Use of the Apollo detachable-tip microcatheter for endovascular embolization of arteriovenous malformations and arteriovenous fistulas. AB - OBJECTIVE Liquid embolic agents have revolutionized endovascular management of arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs). Nonetheless, since 2005, the US FDA has received more than 100 reports of microcatheter breakage or entrapment related to Onyx embolization, including 9 deaths. In 2014, the Apollo detachable-tip microcatheter became the first of its kind available in the US. Since then, few reports on its safety have been published. METHODS The authors conducted a retrospective review of endovascular cases by searching the patient databases at 2 tertiary cerebrovascular centers (Barrow Neurological Institute and University of Pittsburgh Medical Center). Patients who underwent endovascular embolization of an AVM or AVF using the Apollo microcatheter were identified. Patient demographics and lesion characteristics were collected. The authors analyzed Apollo-specific endovascular variables, such as number of microcatheterizations, sessions, and pedicles embolized; microcatheter tip detachment status; obliteration rate; and endovascular- and microcatheter-related morbidity and mortality. RESULTS From July 2014 to October 2016, a total of 177 embolizations using the Apollo microcatheter were performed in 61 patients (mean age 40.3 years). The most frequent presentation was hemorrhage (22/61, 36.1%). Most lesions were AVMs (51/61, 83.6%; mean diameter 30.6 mm). The mean Spetzler-Martin grade was 2.4. Thirty-nine (76.5%) of 51 patients with AVMs underwent resection. Microcatheterization was successful in 172 pedicles. Most patients (50/61, 82%) underwent a single embolization session. The mean number of pedicles per session was 2.5 (range 1-7). Onyx-18 was used in 103 (59.9%), N-butyl cyanoacrylate (NBCA) in 44 (25.6%), and Onyx-34 in 25 (14.5%) of the 172 embolizations. In 45.9% (28/61) of the patients, lesion obliteration of 75% or greater was achieved. Tip detachment occurred in 19.2% (33/172) of microcatheters. Fifty three (86.9%) of the 61 patients who underwent embolization with the Apollo microcatheter had good functional outcomes (modified Rankin Scale score 0-2). No unintended microcatheter fractures or related morbidity was observed. One patient died of intraprocedural complications unrelated to microcatheter selection. In the univariate analysis, microcatheter tip detachment (p = 0.12), single embolized pedicles (p = 0.12), and smaller AVM nidus diameter (p = 0.17) correlated positively with high obliteration rates (> 90%). In the multivariate analysis, microcatheter tip detachment was the only independent variable associated with high obliteration rates (OR 9.5; p = 0.03). CONCLUSIONS The use of the Apollo detachable-tip microcatheter for embolization of AVMs and AVFs is associated with high rates of successful catheterization and obliteration and low rates of morbidity and mortality. The microcatheter was retrieved in all cases, even after prolonged injections in distal branch pedicles, often with significant reflux. This study represents the largest case series on the application of the Apollo microcatheter for neurointerventional procedures. PMID- 29570007 TI - Superiority of constructive interference in steady-state MRI sequencing over T1 weighted MRI sequencing for evaluating cavernous sinus invasion by pituitary macroadenomas. AB - OBJECTIVE Preoperatively determining the extent of parasellar invasion of pituitary macroadenomas is useful for surgical planning and patient counseling. Here, the authors compared constructive interference in steady state (CISS), a T2 weighted gradient-echo MRI sequence, to volume-interpolated breath-hold examination (VIBE), a T1-weighted gradient-echo MRI sequence, for evaluation of cavernous sinus invasion (CSI) by pituitary macroadenomas. METHODS VIBE and CISS images of 98 patients with pituitary macroadenoma were retrospectively analyzed and graded using the modified Knosp classification. The Knosp grades were correlated to surgical findings of CSI, which were determined intraoperatively using 0 degrees and 30 degrees endoscopes. The predictive accuracies for CSI according to the Knosp grades derived from the CISS and VIBE images were compared using receiver operating characteristic (ROC) curves. Postoperative MRI was used to evaluate the gross-total resection (GTR) rates. RESULTS The CSI rate by pituitary macroadenomas was 27.6% (27 of 98 cases). Of 196 assessments (left and right sides of 98 macroadenomas), 45 (23.0%) had different Knosp grades when scored using VIBE versus CISS images. For the VIBE images, 0% of Knosp grade 0, 4.5% of grade 1, 23.8% of grade 2, 42.1% of grade 3A, 100% of grade 3B, and 83.3% of grade 4 macroadenomas were found to have CSI intraoperatively. For the CISS images, 0% of Knosp grade 0, 2.1% of grade 1, 31.3% of grade 2, 56.3% of grade 3A, 100% of grade 3B, and 100% of grade 4 macroadenomas were found to have CSI intraoperatively. Two pituitary macroadenomas were classified as grade 4 on VIBE sequences but grades 3A and 2 on CISS sequences; CSI was not observed intraoperatively in both cases. The GTR rate was 64.3% and 60.0% for high-grade (3A, 3B, and 4) macroadenomas classified using VIBE and CISS sequences, respectively. The areas under the ROC curves were 0.94 and 0.97 for VIBE- and CISS-derived Knosp grades (p = 0.007), respectively. CONCLUSIONS Knosp grades determined using CISS sequence images are better correlated with intraoperative CSI than those determined using VIBE sequence images. CISS sequences may be valuable for the preoperative assessment of pituitary macroadenomas. PMID- 29570008 TI - Intraoperative use of transcranial motor/sensory evoked potential monitoring in the clipping of intracranial aneurysms: evaluation of false-positive and false negative cases. AB - OBJECTIVE Somatosensory and motor evoked potentials (SEPs and MEPs) are often used to prevent ischemic complications during aneurysm surgeries. However, surgeons often encounter cases with suspicious false-positive and false-negative results from intraoperative evoked potential (EP) monitoring, but the incidence and possible causes for these results are not well established. The aim of this study was to investigate the efficacy and reliability of EP monitoring in the microsurgical treatment of intracranial aneurysms by evaluating false-positive and false-negative cases. METHODS From January 2012 to April 2016, 1514 patients underwent surgery for unruptured intracranial aneurysms (UIAs) with EP monitoring at the authors' institution. An EP amplitude decrease of 50% or greater compared with the baseline amplitude was defined as a significant EP change. Correlations between immediate postoperative motor weakness and EP monitoring results were retrospectively reviewed. The authors calculated the sensitivity, specificity, and positive and negative predictive values of intraoperative MEP monitoring, as well as the incidence of false-positive and false-negative results. RESULTS Eighteen (1.19%) of the 1514 patients had a symptomatic infarction, and 4 (0.26%) had a symptomatic hemorrhage. A total of 15 patients showed motor weakness, with the weakness detected on the immediate postoperative motor function test in 10 of these cases. Fifteen false-positive cases (0.99%) and 8 false-negative cases (0.53%) were reported. Therefore, MEP during UIA surgery resulted in a sensitivity of 0.10, specificity of 0.94, positive predictive value of 0.01, and negative predictive value of 0.99. CONCLUSIONS Intraoperative EP monitoring has high specificity and negative predictive value. Both false-positive and false negative findings were present. However, it is likely that a more meticulously designed protocol will make EP monitoring a better surrogate indicator of possible ischemic neurological deficits. PMID- 29570009 TI - Improvement in cognitive function after surgery for low-grade glioma. AB - OBJECTIVE Cognition is a key component in health-related quality of life (HRQoL) and is currently incorporated as a major parameter of outcome assessment in patients treated for brain tumors. The effect of surgery on cognition and HRQoL remains debatable. The authors investigated the impact of resection of low-grade gliomas (LGGs) on cognition and the correlation with various histopathological markers. METHODS A retrospective analysis of patients with LGG who underwent craniotomy for tumor resection at a single institution between 2010 and 2014 was conducted. Of 192 who underwent resective surgery for LGG during this period, 49 had complete pre- and postoperative neurocognitive evaluations and were included in the analysis. These patients completed a full battery of neurocognitive tests (memory, language, attention and working memory, visuomotor organization, and executive functions) pre- and postoperatively. Tumor and surgical characteristics were analyzed, including volumetric measurements and histopathological markers (IDH, p53, GFAP). RESULTS Postoperatively, significant improvement was found in memory and executive functions. A subgroup analysis of patients with dominant side tumors, most of whom underwent intraoperative awake mapping, revealed significant improvement in the same domains. Patients whose tumors were on the nondominant side displayed significant improvement only in memory functions. Positive staining for p53 testing was associated with improved language function and greater extent of resection in dominant-side tumors. GFAP positivity was associated with improved memory in patients whose tumors were on the nondominant side. No correlation was found between cognitive outcome and preoperative tumor volume, residual volume, extent of resection, or IDH1 status. CONCLUSIONS Resection of LGG significantly improves memory and executive function and thus is likely to improve functional outcome in addition to providing oncological benefit. GFAP and pP53 positivity could possibly be associated with improved cognitive outcome. These data support early, aggressive, surgical treatment of LGG. PMID- 29570010 TI - Longitudinal anterior-to-posterior shift of collateral channels in patients with moyamoya disease: an implication for its hemorrhagic onset. AB - OBJECTIVE This study aimed to assess longitudinal changes in the collateral channels originating from the lenticulostriate artery (LSA), posterior communicating artery (PCoA), and anterior and posterior choroidal arteries (AChA and PChA, respectively) during disease progression and/or aging. The impact of collateral channels on onset type was also examined. METHODS This study included 71 involved hemispheres in 41 patients with moyamoya disease. The disease was categorized into 6 stages according to Suzuki's angiographic staging system. The degree of development of each moyamoya vessel was categorized into 3 grades. RESULTS The LSA started to dilate in stage 2, showed the most prominent development in stage 3, and decreased in more advanced stages (p < 0.001). The AChA most notably developed in stage 3 and gradually shrank (p = 0.04). The PCoA started to dilate in stage 3 and showed the most prominent development in stage 4 (p = 0.03). The PChA started to dilate in stage 3 and showed the most prominent development in stages 4 to 5 (p < 0.001). Patient age was negatively related to LSA development (p = 0.01, R = 0.30) and was positively associated with the abnormal dilation and extension of the PCoA (p = 0.02, R = 0.28) and PChA (p < 0.001, R = 0.45). The PCoA, AChA, and PChA more distinctly developed in hemispheres with intracerebral or intraventricular hemorrhage than in hemispheres with ischemic stroke or transient ischemic attack (p < 0.001, p = 0.03, and p = 0.03, respectively). CONCLUSIONS This study suggests that the collateral channels through moyamoya vessels longitudinally shift from the anterior to posterior component during disease progression and aging, which may be closely related to the onset of hemorrhagic stroke in adult moyamoya disease. PMID- 29570011 TI - Clipping as re-treatment strategy after treatment of a cerebral aneurysm with the Woven EndoBridge embolization device: case report. AB - Recently, treatment of cerebral aneurysms with the Woven EndoBridge (WEB) device has become an established endovascular strategy. However, over time, neurosurgeons and neuroradiologists will be confronted with the challenge of how to treat aneurysm recanalization. The authors report the case of a 49-year-old woman who underwent re-treatment with clipping after the recanalization of a 4 * 3-mm anterior communicating artery aneurysm that had previously been treated using a 4 * 3 WEB device. In contrast to the authors' prior experiences with clipping of previously coiled aneurysms, the WEB device was found to have a responsive softness during clip placement, and the aneurysm was more maneuverable. Moreover, evaluation with indocyanine green angiography was easy to perform because of the transparent mesh of the WEB device. No profound scarring or WEB protrusion was noted during surgery, making the procedure easier and less dangerous with regard to additional complications. The authors suggest that re treatment via clipping should be considered in select cases of aneurysm recurrence after treatment with an intraaneurysmal flow diverter. PMID- 29570012 TI - Validation of diffusion tensor imaging tractography to visualize the dentatorubrothalamic tract for surgical planning. AB - OBJECTIVE The dentatorubrothalamic tract (DRTT) has been suggested as the anatomical substrate for deep brain stimulation (DBS)-induced tremor alleviation. So far, little is known about how accurately and reliably tracking results correspond to the anatomical DRTT. The objective of this study was to systematically investigate and validate the results of different tractography approaches for surgical planning. METHODS The authors retrospectively analyzed 4 methodological approaches for diffusion tensor imaging (DTI)-based fiber tracking using different regions of interest in 6 patients with essential tremor. Tracking results were analyzed and validated with reference to MRI-based anatomical landmarks, were projected onto the stereotactic atlas of Morel at 3 predetermined levels (vertical levels -3.6, -1.8, and 0 mm below the anterior commissure posterior commissure line), and were correlated to clinical outcome. RESULTS The 4 different methodologies for tracking the DRTT led to divergent results with respect to the MRI-based anatomical landmarks and when projected onto the stereotactic atlas of Morel. There was a statistically significant difference in the lateral and anteroposterior coordinates at the 3 vertical levels (p < 0.001, 2-way ANOVA). Different fractional anisotropy values ranging from 0.1 to 0.46 were required for anatomically plausible tracking results and led to varying degrees of success. Tracking results were not correlated to postoperative tremor reduction. CONCLUSIONS Different tracking methods can yield results with good anatomical approximation. The authors recommend using 3 regions of interest including the dentate nucleus of the cerebellum, the posterior subthalamic area, and the precentral gyrus to visualize the DRTT. Tracking results must be cautiously evaluated for anatomical plausibility and accuracy in each patient. PMID- 29570013 TI - Value of pituitary gland MRI at 7 T in Cushing's disease and relationship to inferior petrosal sinus sampling: case report. AB - Cushing's disease is caused by adrenocorticotrophic hormone (ACTH)-secreting pituitary adenomas, which are often difficult to identify on standard 1.5-T or 3 T MRI, including dynamic contrast imaging. Inferior petrosal and cavernous sinus sampling remains the gold standard for MRI-negative Cushing's disease. The authors report on a 27-year-old woman with Cushing's disease in whom the results of standard 1.5-T and 3-T MRI, including 1.5-T dynamic contrast imaging, were negative. Inferior petrosal sinus sampling showed a high central-to-peripheral ACTH ratio (148:1) as well as a right-to-left ACTH gradient (19:1), suggesting a right-sided pituitary microadenoma. The patient underwent 7-T MRI, which showed evidence of a right-sided pituitary lesion with focal hypoenhancement not visualized on 1.5-T or 3-T MRI. The patient underwent an endoscopic endonasal transsphenoidal operation, with resection of a right-sided pituitary mass. Postoperatively, she developed clinical symptoms suggestive of adrenal insufficiency and a nadir cortisol level of 1.6 MUg/dl on postoperative day 3, and hydrocortisone therapy was initiated. Permanent histopathology specimens showed Crooke's hyaline change and ACTH-positive cells suggestive of an adenoma. MRI at 7 T may be beneficial in identifying pituitary microadenoma location in cases of standard 1.5-T and 3-T MRI-negative Cushing's disease. In the future, 7 T MRI may preempt inferior petrosal sinus sampling and help in cases of standard and dynamic contrast 1.5-T and 3-T MRI-negative Cushing's disease.

PMID- 29570016 TI - Early and middle childhood developmental, cognitive, and psychiatric outcomes of Malawian children affected by retinopathy positive cerebral malaria. AB - The objective is to determine the short -and long-term developmental, cognitive, and psychiatric effects of retinopathy positive cerebral malaria (CM-R) among young children in a prospective study assessing them around the onset of disease and again 2 years at preschool and again at school age. In total, 109 children were recruited from the Queen Elizabeth Central Hospital in Blantyre, Malawi, (N = 49) with CM-R and non-malaria controls (N = 60). Children were assessed for overall motor, language, and social skills using the Malawi Developmental Assessment Tool (MDAT) at preschool age. At school age, the same children were then given the Kaufman Assessment Battery for Children, second edition (KABC-II), which assessed global cognitive performancememory, and learning; as well as the Test of Variables of Attention (TOVA), which assessed attention. The Achenbach Child Development Checklist (CBCL) was administered at both time points to assess emotional and behavioral patterns. Controls scored significantly better on all KABC-II global domains as well as on the mental processing index than their CM-R group counterparts, but showed no performance differences in the TOVA and CBCL assessments at school age, or in the MDAT and CBCL assessments at preschool age. The MDAT total score was significantly correlated with the KABC-II sequential processing, learning, and mental processing index among CM-R survivors but not among controls. Persisting neurocognitive effects of CM can be captured with the KABC-II at school age. The MDAT at preschool age is correlated with the KABC-II among CM-R survivors and can be used to capture early emerging developmental deficits due to CM-R. PMID- 29570017 TI - Age at death of major cardiovascular diseases in 13 cohorts. The seven countries study of cardiovascular diseases 45-year follow-up. AB - OBJECTIVES: To explore age at death (AD) for major cardiovascular diseases (CVD) and their risk factors in originally middle-aged men followed nearly to extinction in the Seven Countries Study. MATERIALS AND METHODS: Thirteen cohorts of men aged 40-59 years (N = 10,628) in seven countries (USA, Finland, the Netherlands, Italy, Serbia, Greece, Japan) were enrolled in late 1950s and early 1960s and were followed 45 years for mortality. AD was computed for coronary heart disease (CHD), stroke (STR), heart disease of uncertain aetiology (HDUE) and for all-causes. AD was compared across CHD-HDUE-STR. Cox models were computed for each end-point using baseline age, cigarettes smoking, systolic blood pressure and serum cholesterol. RESULTS: After 45 years 92.9% of men had died. The most common CVD death was CHD in most cohorts except some Mediterranean and Japanese cohorts where STR or HDUE were most prevalent. In 13 cohorts mean AD was 74.5, 73.5, 75.7 and 79.1 years, respectively, for all-cause, CHD, STR and HDUE mortality (all possible differences were significant). The difference, across cohorts, between the highest and the lowest mean AD was 12.9, 9.0 and 4.7 years for CHD, HDUE and STR mortality, respectively. Risk factors explored were significant predictors of all three CVD end-points, except serum cholesterol, specific to CHD mortality. CONCLUSIONS: AD is a useful indicator of previous health and aging populations. STR and HDUE are diseases appearing later in life, thus being associated with a higher AD compared with CHD mortality. PMID- 29570018 TI - Preventive Use of a Resin-based Desensitizer Containing Glutaraldehyde on Tooth Sensitivity Caused by In-office Bleaching: A Randomized, Single-blind Clinical Trial. AB - OBJECTIVE: To evaluate the risk and intensity of bleaching-induced tooth sensitivity (TS) after in-office bleaching following topical application of a resin-based glutaraldehyde desensitizer. METHODS: Thirty-three patients were randomly assigned to the experimental (Gluma Desensitizer Liquid, Heraeus Kulzer, Hanau, Germany) and placebo groups. The placebo or Gluma Desensitizer Liquid was applied for one minute prior to application of an in-office bleaching gel. Bleaching was performed with 35% hydrogen peroxide gel (three applications * 15 minutes each) over two sessions, one week apart. The color of the anterior teeth was evaluated before and 21 days after treatment using the VITA Classical shade guide, Bleachedguide 3D, and Easyshade spectrophotometer. TS during and after the bleaching was recorded according to the visual analog (VAS) and numerical rating (NRS) scales. All data were submitted to statistical analysis (alpha=0.05). RESULTS: There was no significant difference in absolute risk or intensity of TS between the two groups (risk and VAS, p=0.93 and 0.31, respectively; NRS, p>=0.45). At the end of the bleaching protocol, tooth whitening was observed in both groups, as evident from color change in shade guide units (DeltaSGU, 4.1 7.1; both guides) and overall color change (DeltaE, 7.4-9.3 units); however, there were no significant differences in whitening between the two groups ( p>0.11). CONCLUSION: Gluma Desensitizer Liquid was not able to reduce the risk or intensity of TS. Bleaching efficacy was not affected by application of the desensitizer. PMID- 29570019 TI - Effect of Various Bleaching Agents on the Surface Composition and Bond Strength of a Calcium Silicate-based Cement. AB - This study aimed to evaluate the morphological and elemental changes that occur on the surface of calcium silicate-based cement (CSC) and to analyze the bond strength of composite resin to CSC after application of various bleaching agents. One hundred twenty-five CSC blocks (Biodentine) were prepared and randomly divided into five groups according to the bleaching agent applied over the material surface (n=25): SP-DW (sodium perborate-distilled water mixture), SP-HP (sodium perborate-3% hydrogen peroxide [H2O2] mixture), CP (37% carbamide peroxide gel), HP (35% H2O2 gel), and a control group (no bleaching agent). After 1 week, scanning electron microscopy provided an analysis of the surface morphology and elemental composition for 10 specimens from each group. Composite resin was placed at the center of each cement surface in the remaining specimens (n=15). A universal testing machine determined shear bond strength (SBS) and fracture patterns were identified with a dental operating microscope. Data were analyzed using one-way analysis of variance and Tukey HSD tests. The cement surface in the CP and HP groups presented changes in structure and elemental distribution compared with the remaining groups. The former groups exhibited a decrease in the calcium level and an increase in the silicon level and presented significantly fewer SBS values than the remaining groups ( p<0.05). Most failures were adhesive in the CP and HP groups, while they were predominantly cohesive in the remaining groups. The bleaching agents with higher concentration induced deterioration of the cement surface and negatively affected the bond strength of the composite resin to CSC. The use of CSC is recommended as a cervical barrier when intracoronal bleaching is performed with a mixture of sodium perborate with water or 3% H2O2. PMID- 29570020 TI - Nanofilled Resin Composite Properties and Clinical Performance: A Review. AB - The aim of this review was to compile recent evidence related to nanofilled resin composite materials regarding the properties and clinical performance. Special attention was given to mechanical properties, such as strength, hardness, abrasive wear, water sorption, and solubility. The clinical performance of nanocomposite materials compared with hybrid resin composites was also addressed in terms of retention and success rates, marginal adaptation, color match, and surface roughness. A search of English peer-reviewed dental literature (2003 2017) from PubMed and MEDLINE databases was conducted using the terms "nanocomposites" or "nanofilled resin composite" and "clinical evaluation." The list was screened, and 82 papers that were relevant to the objectives of this work were included in the review. Mechanical properties of nanocomposites are generally comparable to those of hybrid composites but higher than microfilled composites. Nanocomposites presented lower abrasive wear than hybrids but higher sorption values. Their clinical performance was comparable to that of hybrid composites. PMID- 29570021 TI - Effect of Resin-modified Glass Ionomer Cement Dispensing/Mixing Methods on Mechanical Properties. AB - STATEMENT OF THE PROBLEM: Resin-modified glass ionomer cements (RMGIs) are often used for luting indirect restorations. Hand-mixing traditional cements demands significant time and may be technique sensitive. Efforts have been made by manufacturers to introduce the same cement using different dispensing/mixing methods. It is not known what effects these changes may have on the mechanical properties of the dental cement. PURPOSE: The purpose of this study was to evaluate the mechanical properties (diametral tensile strength [DTS], compressive strength [CS], and fracture toughness [FT]) of RMGIs with different dispensing/mixing systems. METHODS AND MATERIALS: The RMGI specimens (n=14)-RelyX Luting (hand mix), RelyX Luting Plus (clicker-hand mix), RelyX Luting Plus (automix) (3M ESPE), GC Fuji PLUS (capsule-automix), and GC FujiCEM 2 (automix) (GC)-were prepared for each mechanical test and examined after thermocycling (n=7/subgroup) for 20,000 cycles to the following: DTS, CS (ISO 9917-1) and FT (ISO standard 6872; Single-edge V-notched beam method). Specimens were mounted and loaded with a universal testing machine until failure occurred. Two-/one-way analysis of variance followed by Tukey honestly significantly different post hoc test was used to analyze data for statistical significance ( p<0.05). RESULTS: The interaction effect of both dispensing/mixing method and thermocycling was significant only for the CS test of the GC group ( p<0.05). The different dispensing/mixing methods had no effect on the DTS of the tested cements. The CS of GC Fuji PLUS was significantly higher than that of the automix version ( p<0.05). The FT decreased significantly when switching from RelyX (hand mix) to RelyX Luting Plus (clicker-hand mix) and to RelyX Luting Plus (automix) ( p<0.05). Except in the case of the DTS of the GC group and the CS of GC Fuji PLUS, thermocycling had a significant effect reducing the mechanical properties of the RMGI cements ( p<0.05). CONCLUSIONS: Introducing alternative dispensing/mixing methods for mixing RMGIs to reduce time and technique sensitivity may affect mechanical properties and is brand dependent. PMID- 29570022 TI - Do Nanofilled/Nanohybrid Composites Allow for Better Clinical Performance of Direct Restorations Than Traditional Microhybrid Composites? A Systematic Review. AB - This systematic review was carried out to assess the clinical effectiveness of nanofilled and nanohybrid composites used for direct restorations in comparison with microhybrid composites. The guidelines for the preferred reporting items for systematic reviews and meta-analyses were followed. A search of articles published from July 1996 to February 2017 was performed in PubMed, SciVerse Scopus, Latin American and Caribbean Health Sciences, the Scientific Electronic Library Online, and the Cochrane Library. The present review selected only randomized controlled trials comparing the clinical performance of a nanofilled or nanohybrid composite for direct restorations with that of a microhybrid composite. The research found 201 studies. Twenty-one articles fulfilled the criteria of the present review. However, the included studies were characterized by great methodological diversities. As a general trend, nanofilled and nanohybrid composites were found to be capable of clinical performance, marginal quality, and resistance to wear similar to that of traditional composites without showing improved surface characteristics. The risk of bias of included studies was judged unclear or high. The clinical performance of nanofilled/nanohybrid composites was found to be comparable to that of traditional composites in the posterior area. The data concerning anterior and cervical restorations were insufficient. With regard to the esthetic properties, there is a compelling need for studies on anterior teeth in which the operators are kept unaware of the restorative material. Nanofilled/nanohybrid composites seem to be a valid alternative to traditional microhybrid composites, and at the moment, there is low-level evidence attesting a lack of their superiority.

AB - The variation in micro-hardness (HV) within simulated large cavities (10 * 6 mm) filled in one increment with three bulk-fill resin-based composites (BF-RBC) was assessed by means of a universal hardness device. Modern blue and violet-blue light curing units (LCUs) were applied in three different positions, by rotating the LCU in 120 degrees steps. The exposure distance was 3 mm. One center and two peripheral (4-mm apart from the center) HV line profiles were measured in 0.5-mm steps at 24 hours postpolymerization to calculate the depth of cure (DOC). Incident light, irradiance, and spectral distribution were recorded. A multivariate analysis (general linear model) assessed the effect of the varied parameters as well as their interaction terms on HV and DOC. The effect of LCU rotation was not significant ( p=0.109). The DOC varied between 3.46 mm and 5.50 mm and was more strongly influenced by the BF-RBC ( p<0.001, etaP2=0.774), followed by the width of specimen ( p<0.001, etaP2=0.554), while the influence of the LCU was very low ( p<0.06, etaP2=0.070). Whether a BF-RBC filling is cured as well in the periphery as in the center depends more on the material than on the curing unit used. PMID- 29570025 TI - Effect of Tooth-Whitening Procedures on Stained Composite Resins. AB - In this laboratory study, a composite resin was stained to a visibly discernible level using both coffee and red wine over 14 days (change was considered clinically noticeable and significant when DeltaEab*>=2.7). Color change was measured at one, three, seven, and 14 days of staining. Although the nature of color change was different for the two staining solutions, the overall degree of staining (DeltaEab*) rendered by either coffee or wine at each time interval was not significantly different ( p>=0.05). Four whitening protocols were applied to stained composites. Treatment included applications of distilled water (control), Crest Pro-Health [HD] toothpaste, Crest Whitestrips, Opalescence PF bleach (15%), and application of a fine pumice polishing (Preppies). HD toothpaste and Whitestrips were applied daily for 21 days, Opalescence was applied daily for 10 days, and polishing was applied once. Each of the whitening products, applied in a manner simulating at-home or in-office treatment, was effective in producing color improvements (lightening) over controls ( p<0.05), but none of the four treatments produced lightening that was significantly different from the other treatments ( p>=0.05). A comparison of final composite color with that measured at baseline showed that Opalescence returned composite color to an acceptable level following exposure to both staining solutions (DeltaEab*<2.7), Whitestrips returned color close to baseline for wine-stained composites, and HD paste and polishing permitted residual stain to remain (DeltaEab*>=2.7). PMID- 29570024 TI - Effect of Mold Type and Diameter on the Depth of Cure of Three Resin-Based Composites. AB - OBJECTIVE: To evaluate the effects of different mold materials, their diameters, and light-curing units on the mechanical properties of three resin-based composites (RBC). METHODS AND MATERIALS: A conventional nano-filled resin composite (Filtek Supreme Ultra, 3M Oral Care, St Paul, MN, USA) and two bulk fill composites materials, Tetric Evoceram Bulk fill (Ivoclar Vivadent, Schaan, Liechtenstein) and Aura Bulk Fill (SDI, Bayswater, VIC, Australia), were tested. A total of 240 specimens were fabricated using metal or white semitransparent Delrin molds that were 4 or 10 mm in diameter. The RBCs were light cured for 40 seconds on the high-power setting of either a monowave (DeepCure-S, 3M Oral Care) or polywave (Bluephase G2, Ivoclar Vivadent) light-emitting diode (LED) curing unit. The depth of cure was determined using a scraping test, according to the 2009 ISO 4049 test method. Data were analyzed using multivariate analysis of variance followed by Tukey multiple comparison test ( p<0.05). RESULTS: In general, when used for 40 seconds, both LED curing lights achieved the same depth of cure ( p=0.157). However, the mold material and its diameter had a significant effect on the depth of cure of all three RBCs ( p<0.0001). CONCLUSION: Curing with either the polywave or monowave LED curing light resulted in the same depth of cure in the composites. The greatest depth of cure was always achieved using the 10-mm-diameter Delrin mold. Of the three RBCs tested, both Tetric Bulk Fill and Aura achieved a 4-mm depth of cure when tested in the 10-mm-diameter metal mold. Tetric Bulk Fill was the most transparent and had the greatest depth of cure, and the conventional composite had the least depth of cure. Very little violet (<420 nm) light penetrated through 6 mm of any of the RBCs. PMID- 29570026 TI - Influence of Surface Treatment on Composite Adhesion in Noncarious Cervical Lesions: Systematic Review and Meta-analysis. AB - The purpose of this study was to analyze the influence of dentin surface treatments on the retention rate of resin composite restorations in non-carious cervical lesions (NCCLs). Seven randomized clinical trials were included in this review. Data regarding retention rate, type of surface treatment, and the main characteristics of studies were analyzed. Two reviewers performed a literature search up to December 2016 in eight databases: PubMed (Medline), Lilacs, Ibecs, Web of Science, BBO, Scopus, Scielo and The Cochrane Library. Only clinical trials evaluating dentin surface treatments in resin composite restoration in NCCLs were included. Noncontrolled clinical trials, reviews, editorial letters, case reports, case series and studies published in a language other than English, Portuguese, or Spanish were not included. The included studies evaluated different surface treatments, such as using an adhesive system with a frictional technique, drying the dentin, and removing sclerotic dentin by using a bur and applying EDTA before primer use. The analysis considering the mechanical removal of dentin surface with a bur and the application of an adhesive system in a frictional mode showed these treatments improved retention rates of the resin composite restorations in NCCLs ( p<0.05). There is evidence in the literature suggesting that the mechanical removal of dentin surface with a bur and the application of an adhesive system in a frictional mode could improve the retention rates of resin composite restorations in NCCLs. However, the studies showed high heterogeneity, and additional clinical trials are needed to determine the best dentin treatment option in NCCLs.

PMID- 29570027 TI - High Bond Durability of Universal Adhesives on Glass Ceramics Facilitated by Silane Pretreatment. AB - OBJECTIVE:: This study aimed to investigate the long-term effectiveness of ceramic-resin bonding with universal adhesives in non-silane-pretreated and silane-pretreated modes after 10,000 cycles of thermal aging. METHODS AND MATERIALS:: All Bond Universal, Adhese Universal, Clearfil Universal Bond, and Single Bond Universal were selected. Etched lithium disilicate glass ceramics were prepared, randomly assigned to groups, and pretreated with or without ceramic primer containing silane coupling agent prior to the application of universal adhesive (ie, silane-pretreated or non-silane-pretreated mode). The shear bond strength (SBS), microleakage, and field-emission scanning electron microscopy images of the ceramic-resin interfaces were examined after 24 hours of water storage or 10,000 thermal cycles. Light microscopy and confocal laser scanning microscopy (CLSM) were performed to analyze marginal sealing ability. RESULTS:: SBS and microleakage percentage were significantly affected by bonding procedure (non-silane-pretreated or silane-pretreated mode) and aging (24 hours or 10,000 thermal cycles). After the universal adhesives in the non-silane pretreated mode were aged, SBS significantly decreased and microleakage percentage increased. By contrast, the SBS of Adhese Universal, Clearfil Universal Bond, and Single Bond Universal decreased, and the microleakage percentage of all of the adhesives increased in the silane-pretreated mode. However, after aging, the SBS of the silane-pretreated groups were higher and their microleakage percentages lower than those of the non-pretreated groups. In the non-silane-pretreated mode, adhesive failure was dominant and gaps between composite resin and the adhesive layer were significant when observed with CLSM. CONCLUSIONS:: The simplified procedure reduced the ceramic-resin bonding effectiveness of universal adhesives after aging, and additional silane pretreatment helped improve the long-term durability.

AB - It was possible to restore the shape and function of a severely ankylosed tooth by fabricating a ceramic crown for placement on a resin reconstruction supported by mini fiberglass posts. By increasing the retention of the morphological reconstruction for the future support of indirect restorations, cementable intradentinal fiberglass posts enhance the longevity of these restorations. Ultimately, all proposals that seek to improve the long-term prognosis of restorations on ankylosed teeth, especially severely impacted ones, are of extreme clinical relevance.

AB - This article describes a novel application of Skills for Psychological Recovery (SPR)-a brief, early intervention developed by the National Center for Posttraumatic Stress Disorder and the National Child Traumatic Stress Network-for families grieving the violent death of a loved one. Drawing on conservation of resources theory, SPR incorporates cognitive-behavioral skills-building modules to help survivors cope with trauma-related distress and posttrauma resource loss. The authors describe the intervention and illustrate the use of SPR for violent loss by presenting data from two cases involving a suicide survivor and a homicide survivor. Implications for future research are discussed. PMID- 29570031 TI - Maternal Grief: A Qualitative Investigation of Mothers' Responses to the Death of a Child From Cancer. AB - This study explored bereaved mothers' responses to the death of a child from cancer, with a focus on identifying adaptive and complicated grief reactions. To understand the unique meaning of their loss, in-depth interviews were conducted with 13 mothers at two time points. Interpretative phenomenological analysis guided by meaning-making theories of loss-revealed five master categories: the perceptions of the child's life with cancer and death from the disease, changed self-identity, coping style, developing an ongoing relationship to the deceased child, and the postdeath social environment. Each of these master categories and associated subthemes provided insights into the characteristics of the bereaved mothers' adaptive and complicated grief responses to their loss. Given all the mothers evidenced multiple forms or types of these responses over time, they could not be categorized as adaptive or complicated grievers. However, the varying proportions of each of these responses highlighted differences in overall bereavement adaptation. PMID- 29570032 TI - Classroom-Based Physical Activity and Sedentary Behavior Interventions in Adolescents: A Systematic Review and Meta-Analysis. AB - BACKGROUND: It is reported that 81% of adolescents are insufficiently active. Schools play a pivotal role in promoting physical activity (PA) and reducing sedentary behavior (SB). The aim of this systematic review and meta-analysis was to evaluate classroom-based PA and SB interventions in adolescents. METHODS: A search strategy was developed using the Population Intervention Comparison Outcome Study (PICOS) design framework. Articles were screened using strict inclusion criteria. Study quality was assessed using the Effective Public Health Practice Project quality assessment tool ( http://www.ephpp.ca/tools.html ). Outcome data for preintervention and postintervention were extracted, and effect sizes were calculated using Cohen's d. RESULTS: The strategy yielded 7574 potentially relevant articles. Nine studies were included for review. Study quality was rated as strong for 1 study, moderate for 5 studies, and weak for 3 studies. Five studies were included for meta-analyses, which suggested that the classroom-based interventions had a nonsignificant effect on PA (P = .55, d = 0.05) and a small, nonsignificant effect on SB (P = .16, d = -0.11). CONCLUSION: Only 9 relevant studies were found, and the effectiveness of the classroom-based PA and SB interventions varied. Based on limited empirical studies, there is not enough evidence to determine the most effective classroom-based methodology to increase PA and SB. PMID- 29570033 TI - Taking the next step in publication productivity analysis in pediatric neurosurgery. AB - OBJECTIVE There has been an increasing interest in the quantitative analysis of publishing within the field of neurosurgery at the individual, group, and institutional levels. The authors present an updated analysis of accredited pediatric neurosurgery training programs. METHODS All 28 Accreditation Council for Pediatric Neurosurgery Fellowship programs were contacted for the names of pediatric neurosurgeons who were present each year from 2011 through 2015. Faculty names were queried in Scopus for publications and citations during this time period. The 5-year institutional Hirsch index [i h(5)-index] and revised 5 year institutional h-index [i r(5)-index] were calculated to rank programs. Each publication was reviewed to determine authorship value, tier of research, clinical versus basic science research, subject matter, and whether it was pediatrics-specific. A unique 3-tier article classification system was introduced to stratify clinical articles by quality and complexity, with tier 3 being the lowest tier of publication (e.g., case reports) and tier 1 being the highest (e.g., randomized controlled trials). RESULTS Among 2060 unique publications, 1378 (67%) were pediatrics-specific. The pediatrics-specific articles had a mean of 15.2 citations per publication (median 6), whereas the non-pediatrics-specific articles had a mean of 23.0 citations per publication (median 8; p < 0.0001). For the 46% of papers that had a pediatric neurosurgeon as first or last author, the mean number of citations per publication was 12.1 (median 5.0) compared with 22.5 (median 8.0) for those in which a pediatric neurosurgeon was a middle author (p < 0.0001). Seventy-nine percent of articles were clinical research and 21% were basic science or translational research; however, basic science and translational articles had a mean of 36.9 citations per publication (median 15) compared with 12.6 for clinical publications (median 5.0; p < 0.0001). Among clinical articles, tier 1 papers had a mean of 15.0 citations per publication (median 8.0), tier 2 papers had a mean of 18.7 (median 8.0), and tier 3 papers had a mean of 7.8 (median 3.0). Neuro-oncology papers received the highest number of citations per publication (mean 25.7). The most common journal was the Journal of Neurosurgery: Pediatrics (20%). MD/PhD faculty members had significantly more citations per publication than MD faculty members (mean 26.7 vs 14.0; p < 0.0001) and also a higher number of publications per author (mean 38.6 vs 20.8). The median i h(5)- and i r(5)-indices per program were 14 (range 5-48) and 10 (range 5.6-37.2), respectively. The mean i r(5)/i h(5)-index ratio was 0.8. The top 5 fellowship programs (in descending order) as ranked by the i h(5)-index corrected for number of faculty members were The Hospital for Sick Children, Toronto; Children's Hospital of Pittsburgh; University of California, San Francisco Benioff Children's Hospital; Seattle Children's Hospital; and St. Louis Children's Hospital. CONCLUSIONS About two-thirds of publications authored by pediatric neurosurgeons are pediatrics-specific, although non-pediatrics-specific articles averaged more citations. Most of the articles authored by pediatric neurosurgeons are clinical, with basic and translational articles averaging more citations. Neurosurgeons with PhD degrees averaged more total publications and more citations per publication. In all, this is the most advanced and informative analysis of publication productivity in pediatric neurosurgery to date. PMID- 29570034 TI - Split laminotomy versus conventional laminotomy: postoperative outcomes in pediatric patients. AB - OBJECTIVE Split laminotomy is a technique for accessing the spinal canal from the posterior midline that minimizes muscle dissection and bone removal. Benefits of this approach in minimizing postoperative pain and muscle atrophy in the adult population have been reported, but pediatric data are limited. Herein, the authors evaluate the benefits of the split laminotomy technique in pediatric patients. METHODS Data obtained in patients who underwent posterior spine surgery at Children's Hospital of Wisconsin for an intradural midline pathology between April 2008 and June 2015 were reviewed retrospectively. Each patient was assigned to one of two groups, the split-laminotomy or conventional-laminotomy group. The primary outcomes assessed were mean daily pain score, total opioid use over a period of 72 hours after surgery, and the degree of paraspinal muscle atrophy and fat infiltration found on short-term (1-4 months) and long-term (1-4 years) follow-up spine MRI studies. RESULTS A total of 117 patients underwent lumbar level surgery (83 conventional laminotomy, 34 split laminotomy), and 8 patients underwent thoracic-level surgery (4 in each group). No significant difference in the mean daily pain scores between groups was found. The daily opioid use was significantly lower in the split-laminotomy group on postoperative day 0 (POD0) and POD1 but not on POD2 (p = 0.01, 0.01, and 0.10, respectively). The total opioid use over the 72-hour postoperative period was significantly lower in the split-laminotomy group (p = 0.0008). The fat/muscle ratio was significantly higher in both the short-term and long-term follow-up periods in the conventional laminotomy group (p = 0.01 and 0.0002, respectively). The rate of change of paraspinal muscle fat infiltration was significantly lower in the split laminotomy group than in the conventional-laminotomy group (p = 0.007). The incidence of complications was not significantly different between groups (p = 0.08). CONCLUSIONS This study was of the largest series reported thus far of pediatric patients who underwent split laminotomy and the only controlled study that has involved children. The authors' results reinforce the short-term benefit of split laminotomy in minimizing acute postoperative pain and long-term benefits of decreasing muscle atrophy and fatty degeneration, which are known to be associated with the development of chronic pain and spinal instability. Additional efforts for assessing long-term effects in the development of chronic pain, spinal instability, and spinal deformity are still necessary. PMID- 29570035 TI - Predictors of mortality in children with myelomeningocele and symptomatic Chiari type II malformation. AB - OBJECTIVE Chiari malformation type II (CM-II) in myelomeningocele is associated with a significant rate of mortality and poor outcome. Death is frequently heralded by the onset or progression of neurological symptoms. The authors sought to identify predictors of poor outcome and mortality within the myelomeningocele population at Children's Hospital of Pittsburgh. METHODS A retrospective chart and radiology review was performed on all infants who underwent primary closure of a myelomeningocele defect at Children's Hospital of Pittsburgh between the years of 1995 and 2015. Preoperative symptoms and signs leading to CM-II decompression, as well as operative details and postoperative changes in these symptoms and signs, were investigated in detail and correlated to outcome. Poor outcome was defined as death, stridor, or ventilator dependence. Deceased patients were separately assessed within this subgroup. RESULTS Thirty-two (21%) of 153 patients were found to have symptomatic CM-II. Of the 32 patients meeting inclusion criteria, 12 (38%) had poor outcomes. Eight patients (25%) died since initial presentation; 5 of these patients (16% of the overall cohort) died within the 1st year of life and 3 (9%) died during adolescence. Seven (88%) of the 8 patients who died had central apnea on presentation (p = 0.001) and 7 (44%) of the 16 patients who developed symptoms in the first 3 months of life died, compared with 1 (6.3%) of 16 who developed symptoms later in childhood (p = 0.04). The median Apgar score at 1 minute was 4.5 for patients who died and 8 for surviving patients (p = 0.006). The median diameter of the myelomeningocele defect was 5.75 cm for patients who died and 5 for those who survived (p = 0.01). The anatomical level of defect trended toward higher levels in patients who died, with 4 patients in that group having an anatomical level at L-2 or higher compared with 5 of the surviving patients (p = 0.001). The median initial head circumference for the 5 patients dying in the 1st year of life was 41.5 cm, versus 34 cm for all other patients (p = 0.01). CONCLUSIONS CM-II in spina bifida is associated with a significant mortality rate even when surgical intervention is performed. Death is more frequent in symptomatic patients presenting prior to 1 year of age. Late deaths are associated with symptom progression despite aggressive surgical and medical intervention. In this patient cohort, death was more likely in patients with symptomatic presentation during the first 3 months of life, low Apgar scores, large myelomeningocele defects, early central apnea, and large head circumference at birth.

AB - Transglutaminase (TG) is an essential enzyme to catalyze cross-linking reactions of epidermal proteins. Recently, we biochemically characterized human skin TG orthologues for medaka (Oryzias latipes), a model fish. By genome editing, gene modified fishes for the two orthologues were obtained, both of which lack the ordinal enzymes. These fish appeared to exhibit higher susceptibility to osmolality at the period of larvae. PMID- 29570039 TI - The Association of Health-Related Fitness and Chronic Absenteeism Status in New York City Middle School Youth. AB - BACKGROUND: Extensive research demonstrates the benefits of fitness on children's health and academic performance. Although decreases in health-related fitness may increase school absenteeism, multiple years of prospective, child-level data are needed to examine whether fitness changes predict subsequent chronic absenteeism status. METHODS: Six cohorts of New York City public school students were followed from grades 5-8 (2006/2007-2012/2013; N = 349,381). A longitudinal 3 level logistic generalized linear mixed model with random intercepts was used to test the association of individual children's changes in fitness and 1-year lagged chronic absenteeism. RESULTS: The odds of chronic absenteeism increased 27% [odds ratio (OR) 95% confidence interval (CI), 1.25-1.30], 15% (OR 95% CI, 1.13-1.18), 9% (OR 95% CI, 1.07-1.11), and 1% (OR 95% CI, 0.98-1.04), for students who had a >20% decrease, 10%-20% decrease, <10% increase or decrease, and 10%-20% increase in fitness, respectively, compared with >20% fitness increase. CONCLUSION: These findings contribute important longitudinal evidence to a cross-sectional literature, demonstrating reductions in youth fitness may increase absenteeism. Given only 25% of youth aged 12-15 years achieve the recommended daily 60 minutes or more of moderate to vigorous physical activity, future work should examine the potential for youth fitness interventions to reduce absenteeism and foster positive attitudes toward lifelong physical activity. PMID- 29570038 TI - Endoplasmic reticulum stress epigenetics is related to adiposity, dyslipidemia, and insulin resistance. AB - Unresolved ER stress is involved in the onset and progression of several obesity related metabolic disorders, including dyslipidemia and insulin resistance. Different epigenetic modifications may regulate ER stress response and consequently disease risks. These epigenetic phenomena encompass DNA and histone methylation patterns in ER stress genes and downstream signaling molecules, as well as microRNA expression. Our results suggest potential associations of methylation signatures at ER regulatory genes in white blood cells with an abdominal/central obesity marker (waist circumference), dyslipidemia, and insulin resistance. Interestingly, most of these genes were implicated in ER stress, as revealed by pathway enrichment analysis. Together, these findings add knowledge into the current understanding of relationships between obesity and accompanying complications with epigenetics and ER stress. Here, we comment about the implication of ER stress in central/abdominal adiposity, dyslipidemia, and insulin resistance, with an emphasis on the role that epigenetics may play on these pathological processes. PMID- 29570036 TI - Anti-miRNA oligonucleotides: A comprehensive guide for design. AB - MicroRNAs (miRNAs) are small, non-coding RNA molecules that regulate gene expression post-transcriptionally. As a consequence of their function towards mRNA, miRNAs are widely associated with the pathogenesis of several human diseases, making miRNAs a target for new therapeutic strategies based on the control of their expression. Indeed, numerous works were published in the past decades showing the potential use of antisense oligonucleotides to target aberrant miRNAs (AMOs) involved in several human pathologies. New classes of chemical-modified-AMOs, including locked nucleic acid oligonucleotides, have recently proved their worth in silencing miRNAs. A correct design of a specific AMOs can help to improve their performance and potency towards the target miRNA by increasing for instance nuclease resistance and target affinity. This review outlines the technologies involved to suppress aberrant miRNAs. From the design strategies used in AMOs to its application in novel miRNA-based therapeutics and detection methodologies. PMID- 29570040 TI - Chemical warfare in Colombia, evidentiary ecologies and senti-actuando practices of justice. AB - Between 1994 and 2015, militarized aerial fumigation was a central component of US-Colombia antidrug policy. Crop duster planes sprayed a concentrated formula of Monsanto's herbicide, glyphosate, over illicit crops, and also forests, soils, pastures, livestock, watersheds, subsistence food and human bodies. Given that a national peace agreement was signed in 2016 between FARC-EP guerrillas and the state to end Colombia's over five decades of war, certain government officials are quick to proclaim aerial fumigation of glyphosate an issue of the past. Rural communities, however, file quejas (complaints or grievances) seeking compensation from the state for the ongoing effects of the destruction of their licit agro forestry. At the interfaces of feminist science and technology studies and anthropology, this article examines how evidentiary claims are mobilized when war deeply politicizes and moralizes technoscientific knowledge production. By ethnographically tracking the grievances filed by small farmers, I reveal the extent to which evidence circulating in zones of war - tree seedlings, subsistence crops, GPS coordinates and bureaucratic documents - retains (or not) the imprints of violence and toxicity. Given the systematic rejection of compensation claims, farmers engage in everyday material practices that attempt to transform chemically degraded ecologies. These everyday actualizations of justice exist both alongside and outside contestation over the geopolitically backed violence of state law. Rather than simply contrasting everyday acts of justice with denunciatory claims made against the state, farmers' reparative practices produce an evidentiary ecology that holds the state accountable while also ' senti-actuando' (feel-acting) alternative forms of justice.

AB - Objective To correlate the clinical aspects of symptomatic patients with chronic articular disc displacement with reduction with alterations in the articular disc (AD) morphology and sagittal position. Methods Records from 109 patients were selected that included data on AD morphology and sagittal position as determined by MRI. According to the MRI results, the sagittal position and AD morphology with opened and closed mouth were correlated with many clinical variables. Results More than half of the patients studied were female, and the biconcave and hemiconvex morphologies were most common. Thirty-four patients (31.3%) presented with restricted maximum interincisal distance (MID). The biplanar morphology was associated with eccentric bruxism and MID (p < 0.05). Visual analog scale (VAS) scores between 2 and 7 were shown to be risk factors (p < 0.05). Conclusion The mouth position can influence AD morphology and eccentric bruxism. VAS scores and unknown etiology were risk factors. PMID- 29570043 TI - Developing a fatigue questionnaire for Chinese civil aviation pilots. AB - OBJECTIVE: To assess the fatigue risk is an important challenge in improving flight safety in the aviation industry. The aim of this study was to develop a comprehensive fatigue risk management indicators system and a fatigue questionnaire for Chinese civil aviation pilots. METHODS: Participants included 74 civil aviation pilots (all males). They finished the questionnaire in 20 min before a flight mission. Estimation of internal consistency with Cronbach's alpha and Student's t test as well as Pearson's correlation analysis were the main statistical methods. RESULTS: The results revealed that the fatigue questionnaire had acceptable internal consistency reliability and construct validity; there were significant differences in fatigue scores between international and domestic flight pilots. Also, some international flight pilots, who had taken medications as a sleep aid, had worse sleep quality than those who had not. Long-endurance flights across time zones caused significant differences in circadian rhythm. CONCLUSIONS: The fatigue questionnaire can be used to measure Chinese civil aviation pilots' fatigue, which provides a reference for a fatigue risk management system for civil aviation pilots. PMID- 29570044 TI - Alteplase for the treatment of acute ischemic stroke in patients with low National Institutes of Health Stroke Scale and not clearly disabling deficits (Potential of rtPA for Ischemic Strokes with Mild Symptoms PRISMS): Rationale and design. AB - Rationale Over half of acute ischemic stroke patients have a low National Institutes of Health Stroke Scale of 0-5 and up to two-thirds may not appear clearly disabled at presentation. The efficacy of intravenous alteplase for the latter group is not known. Aim Potential of rtPA for Ischemic Strokes with Mild Symptoms (PRISMS) was designed to evaluate the safety and efficacy of intravenous alteplase for the treatment of acute ischemic stroke with National Institutes of Health Stroke Scale 0-5 and without clearly disabling deficits. Sample size estimates A maximum of 948 subjects were required to test the superiority hypothesis with 80% power, according to a one-sided 0.025 level of significance. Methods and design PRISMS was a multicenter, randomized, double-blind, placebo controlled phase 3b clinical trial. Patients were randomized to the active arm (intravenous alteplase standard dose of 0.9 mg/kg, up to a maximum of 90 mg, plus oral aspirin placebo) or the control arm (intravenous alteplase placebo plus active oral aspirin dose of 325 mg). Study outcome The primary efficacy endpoint was favorable functional outcome, defined as a modified Rankin Scale score 0 or 1 assessed at 90-day postrandomization. PMID- 29570045 TI - Preoperative full-length standing radiographs and revision rates in lumbar degenerative scoliosis. AB - OBJECTIVE Full-length (36-inch) standing spine radiographs are commonly used by spine surgeons to evaluate patients with lumbar degenerative scoliosis (LDS). Despite this practice, the impact of these images on preoperative decision making and the rate of revision surgery has not been analyzed. The purpose of this study is to determine if preoperative full-length standing spine radiographs improve surgical decision making by decreasing the rate of revision surgery in patients with LDS. METHODS From the Health Care Service Corporation administrative claims database, the authors identified patients 50-80 years of age with LDS who had undergone surgery including posterior lumbar decompression and fusion over 2-6 levels and with at least 5 years of continuous coverage after the index surgery. Patients were stratified into the following groups, according to the preoperative imaging studies performed within 6 months before their index surgery: lumbar spine MRI studies only, lumbar spine MRI studies and standard lumbar spine radiographs, CT myelograms, and full-length standing spine radiographs. Survival analysis was performed with the occurrence of a revision within 5 years of the index surgery as the outcome of interest. RESULTS A total of 411 patients were included in the study after applying the inclusion and exclusion criteria. Revision surgery within 5 years after the index procedure was most frequent in the patients with preoperative MRI only (41.8%), followed by the patients with a CT myelogram (30.4%) and those with MRI and standard radiographs (24.8%). The lowest revision rate was seen among those with long-cassette standing radiographs (11.1%). Patients whose preoperative evaluation included full-length standing radiographs (OR 0.353, p = 0.034) and MRI studies plus radiographs (OR 0.650, p = 0.022) were less likely to require revision surgery at 5 years after the index procedure. CONCLUSIONS An assessment of standing alignment using full-length (36 inch) standing radiographs may be beneficial in reducing the risk of revision surgery in patients with lumbar scoliosis. This observation was not limited to patients with large curves or substantial deformity. PMID- 29570046 TI - Sagittal radiographic parameters demonstrate weak correlations with pretreatment patient-reported health-related quality of life measures in symptomatic de novo degenerative lumbar scoliosis: a European multicenter analysis. AB - OBJECTIVE Previous studies have demonstrated that among patients with adult spinal deformity (ASD), sagittal plane malalignment is poorly tolerated and correlates with suboptimal patient-reported health-related quality of life (HRQOL). These studies included a broad range of radiographic abnormalities and various types of ASD. However, the clinical and radiographic characteristics of de novo degenerative lumbar scoliosis (DNDLS), a subtype of ASD, may influence previously reported correlation strengths. The aim of this study was to correlate sagittal radiographic parameters with pretreatment HRQOL in patients with symptomatic DNDLS. METHODS In this multicenter retrospective study of prospectively collected data, 74 patients with symptomatic DNDLS were enrolled based on anteroposterior and lateral 36-inch standing radiographs. Measurements included Cobb angle, coronal imbalance, pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), sagittal vertical axis (SVA), thoracic kyphosis, pelvic incidence minus lumbar lordosis (PI-LL), T1-pelvic angle, and global tilt. HRQOL questionnaires included the Oswestry Disability Index (ODI), Scoliosis Research Society (SRS-22r), 36-item Short-Form Health Survey, and numeric rating scale (NRS) for back and leg pain. Correlations between radiographic parameters and HRQOL were assessed. Finally, HRQOL and increasing severity of sagittal modifiers (SVA, PI-LL, and PT) were evaluated. RESULTS Weak correlations were found between SVA and ODI (r = 0.296, p < 0.05) and PT with NRS back pain and the SRS pain domain (r = -0.260, p < 0.05, and r = 0.282, p < 0.05, respectively). Other sagittal radiographic parameters did not show any significant correlation with HRQOL. No significant differences in HRQOL were found concerning the increasing severity of PT, PI-LL, and SVA. CONCLUSIONS While DNDLS is a severe disabling condition, no noteworthy association between clinical and sagittal radiographic parameters was found through this study, demonstrating that sagittal radiographic parameters should not be considered the unique predictor of pretreatment suboptimal health status in this specific group of patients. Future studies addressing classification and treatment algorithms will have to take into account the existing subgroups of ASD. PMID- 29570047 TI - Painless motor radiculopathy of the cervical spine: clinical and radiological characteristics and long-term outcomes after operative decompression. AB - OBJECTIVE Various neurological diseases are known to cause progressive painless paresis of the upper limbs. In this study the authors describe the previously unspecified syndrome of compression-induced painless cervical radiculopathy with predominant motor deficit and muscular atrophy, and highlight the clinical and radiological characteristics and outcomes after surgery for this rare syndrome, along with its neurological differential diagnoses. METHODS Medical records of 788 patients undergoing surgical decompression due to degenerative cervical spine diseases between 2005 and 2014 were assessed. Among those patients, 31 (3.9%, male to female ratio 4.8 to 1, mean age 60 years) presented with painless compressive cervical motor radiculopathy due to neuroforaminal stenosis without signs of myelopathy; long-term evaluation was available in 23 patients with 49 symptomatic foraminal stenoses. Clinical, imaging, and operative findings as well as the long-term course of paresis and quality of life were analyzed. RESULTS Presenting symptoms (mean duration 13.3 months) included a defining progressive flaccid radicular paresis (median grade 3/5) without any history of radiating pain (100%) and a concomitant muscular atrophy (78%); 83% of the patients were smokers and 17% patients had diabetes. Imaging revealed a predominantly anterior nerve root compression at the neuroforaminal entrance in 98% of stenoses. Thirty stenoses (11 patients) were initially decompressed via an anterior surgical approach and 19 stenoses (12 patients) via a posterior surgical approach. Overall reoperation rate due to new or recurrent stenoses was 22%, with time to reoperation shorter in smokers (p = 0.033). Independently of the surgical procedure chosen, long-term follow-up (mean 3.9 years) revealed a stable or improved paresis in 87% of the patients (median grade 4/5) and an excellent general performance and quality of life. CONCLUSIONS Painless cervical motor radiculopathy predominantly occurs due to focal compression of the anterior nerve root at the neuroforaminal entrance. Surgical decompression is effective in stabilizing or improving motor function with a resulting favorable long-term outcome. PMID- 29570048 TI - Key drivers of patient satisfaction in lumbar spine surgery. AB - OBJECTIVE The Patient Experience of Care, composed of 9 dimensions derived from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, is being used by the Centers for Medicare & Medicaid Services to adjust hospital reimbursement. Currently, there are minimal data on how scores on the constituent HCAHPS items impact the global dimension of satisfaction, the Overall Hospital Rating (OHR). The purpose of this study was to determine the key drivers of overall patient satisfaction in the setting of inpatient lumbar spine surgery. METHODS Demographic and preoperative patient characteristics were obtained. Patients selecting a top-box score for OHR (a 9 or 10 of 10) were considered to be satisfied with their hospital experience. A baseline multivariable logistic regression model was then developed to analyze the association between patient characteristics and top-box OHR. Then, multivariable logistic regression models adjusting for patient-level covariates were used to determine the association between individual components of the HCAHPS survey and a top-box OHR. RESULTS A total of 453 patients undergoing lumbar spine surgery were included, 80.1% of whom selected a top-box OHR. Diminishing overall health status (OR 0.63, 95% CI 0.43-0.91) was negatively associated with top-box OHR. After adjusting for potential confounders, the survey items that were associated with the greatest increased odds of selecting a top-box OHR were: staff always did everything they could to help with pain (OR 12.5, 95% CI 6.6-23.7), and nurses were always respectful (OR 11.0, 95% CI 5.3-22.6). CONCLUSIONS Patient experience of care is increasingly being used to determine hospital and physician reimbursement. The present study analyzed the key drivers of patient experience among patients undergoing lumbar spine surgery and found several important associations. Patient overall health status was associated with top-box OHR. After adjusting for potential confounders, staff always doing everything they could to help with pain and nurses always being respectful were the strongest predictors of overall satisfaction in this population. These findings highlight opportunities for quality improvement efforts in the spine care setting. PMID- 29570049 TI - Editorial. The relevance of sagittal radiographic parameters. PMID- 29570050 TI - Forniceal deep brain stimulation induces gene expression and splicing changes that promote neurogenesis and plasticity. AB - Clinical trials are currently underway to assess the efficacy of forniceal deep brain stimulation (DBS) for improvement of memory in Alzheimer's patients, and forniceal DBS has been shown to improve learning and memory in a mouse model of Rett syndrome (RTT), an intellectual disability disorder caused by loss-of function mutations in MECP2. The mechanism of DBS benefits has been elusive, however, so we assessed changes in gene expression, splice isoforms, DNA methylation, and proteome following acute forniceal DBS in wild-type mice and mice lacking Mecp2. We found that DBS upregulates genes involved in synaptic function, cell survival, and neurogenesis and normalized expression of ~25% of the genes altered in Mecp2-null mice. Moreover, DBS induced expression of 17-24% of the genes downregulated in other intellectual disability mouse models and in post-mortem human brain tissue from patients with Major Depressive Disorder, suggesting forniceal DBS could benefit individuals with a variety of neuropsychiatric disorders. PMID- 29570051 TI - The yeast H+-ATPase Pma1 promotes Rag/Gtr-dependent TORC1 activation in response to H+-coupled nutrient uptake. AB - The yeast Target of Rapamycin Complex 1 (TORC1) plays a central role in controlling growth. How amino acids and other nutrients stimulate its activity via the Rag/Gtr GTPases remains poorly understood. We here report that the signal triggering Rag/Gtr-dependent TORC1 activation upon amino-acid uptake is the coupled H+ influx catalyzed by amino-acid/H+ symporters. H+-dependent uptake of other nutrients, ionophore-mediated H+ diffusion, and inhibition of the vacuolar V-ATPase also activate TORC1. As the increase in cytosolic H+ elicited by these processes stimulates the compensating H+-export activity of the plasma membrane H+-ATPase (Pma1), we have examined whether this major ATP-consuming enzyme might be involved in TORC1 control. We find that when the endogenous Pma1 is replaced with a plant H+-ATPase, H+ influx or increase fails to activate TORC1. Our results show that H+ influx coupled to nutrient uptake stimulates TORC1 activity and that Pma1 is a key actor in this mechanism. PMID- 29570052 TI - Normal mitochondrial function in Saccharomyces cerevisiae has become dependent on inefficient splicing. AB - Self-splicing introns are mobile elements that have invaded a number of highly conserved genes in prokaryotic and organellar genomes. Here, we show that deletion of these selfish elements from the Saccharomyces cerevisiae mitochondrial genome is stressful to the host. A strain without mitochondrial introns displays hallmarks of the retrograde response, with altered mitochondrial morphology, gene expression and metabolism impacting growth and lifespan. Deletion of the complete suite of mitochondrial introns is phenocopied by overexpression of the splicing factor Mss116. We show that, in both cases, abnormally efficient transcript maturation results in excess levels of mature cob and cox1 host mRNA. Thus, inefficient splicing has become an integral part of normal mitochondrial gene expression. We propose that the persistence of S. cerevisiae self-splicing introns has been facilitated by an evolutionary lock-in event, where the host genome adapted to primordial invasion in a way that incidentally rendered subsequent intron loss deleterious. PMID- 29570053 TI - The NIH must reduce disparities in funding to maximize its return on investments from taxpayers. AB - New data from the NIH reveal that the scientific return on its sponsored research reaches a maximum at around $400,000 of annual support per principal investigator. We discuss the implications of this 'sweet spot' for funding policy, and propose that the NIH should limit both the minimum and maximum amount of funding per researcher. PMID- 29570054 TI - Optimization-Based Image Reconstruction From Low-Count, List-Mode TOF-PET Data. AB - OBJECTIVE: We investigate an optimization-based approach to image reconstruction from list-mode data in digital time-of-flight (TOF) positron emission tomography (PET) imaging. METHOD: In the study, the image to be reconstructed is designed as a solution to a convex, non-smooth optimization program, and a primal-dual algorithm is developed for image reconstruction by solving the optimization program. The algorithm is first applied to list-mode TOF-PET data of a typical count level from physical phantoms and a human subject. Subsequently, we explore the algorithm's potential for image reconstruction in low-dose and/or fast TOF PET imaging of practical interest by applying the algorithm to list-mode TOF-PET data of different, low-count levels from the same physical phantoms and human subject. RESULTS: Visual inspection and quantitative-metric analysis reveal that the optimization reconstruction approach investigated can yield images with enhanced spatial and contrast resolution, suppressed image noise, and increased axial volume coverage over the reference images obtained with a standard clinical reconstruction algorithm especially for low-dose TOF-PET data. SIGNIFICANCE: The optimization-based reconstruction approach can be exploited for yielding insights into potential quality upper bound of reconstructed images in, and design of scanning protocols of, TOF-PET imaging of practical significance. PMID- 29570055 TI - A Low-Power Current-Reuse Analog Front-End for High-Density Neural Recording Implants. AB - Studying brain activity in vivo requires collecting bioelectrical signals from several microelectrodes simultaneously in order to capture neuron interactions. In this work, we present a new current-reuse analog front-end (AFE), which is scalable to very large numbers of recording channels, thanks to its small implementation silicon area and its low-power consumption. This current-reuse AFE, which is including a low-noise amplifier (LNA) and a programmable gain amplifier (PGA), employs a new fully differential current-mirror topology using fewer transistors, and improving several design parameters, such as power consumption and noise, over previous current-reuse amplifier circuit implementations. We show that the proposed current-reuse amplifier can provide a theoretical noise efficiency factor (NEF) as low as 1.01, which is the lowest reported theoretical NEF provided by an LNA topology. A foue-channel current reuse AFE implemented in a CMOS 0.18-MUm technology is presented as a proof-of concept. T-network capacitive circuits are used to decrease the size of input capacitors and to increase the gain accuracy in the AFE. The measured performance of the whole AFE is presented. The total power consumption per channel, including the LNA and the PGA stage, is 9 MUW (4.5 MUW for LNA and 4.5 MUW for PGA), for an input referred noise of 3.2 MUVrms, achieving a measured NEF of 1.94. The entire AFE presents three selectable gains of 35.04, 43.1, and 49.5 dB, and occupies a die area of 0.072 mm2 per channel. The implemented circuit has a measured inter channel rejection ratio of 54 dB. In vivo recording results obtained with the proposed AFE are reported. It successfully allows collecting low-amplitude extracellular action potential signals from a tungsten wire microelectrode implanted in the hippocampus of a laboratory mouse. PMID- 29570056 TI - Ultracompact Implantable Design With Integrated Wireless Power Transfer and RF Transmission Capabilities. AB - This paper presents an ultracompact design of biomedical implantable devices with integrated wireless power transfer (WPT) and RF transmission capabilities for implantable medical applications. By reusing the spiral coil in an implantable device, both RF transmission and WPT are realized without the performance degradation of both functions in ultracompact size. The complete theory of WPT based on magnetic resonant coupling is discussed and the design methodology of an integrated structure is presented in detail, which can guide the design effectively. A system with an external power transmitter and implantable structure is fabricated to validate the proposed approach. The experimental results show that the implantable structure can receive power wirelessly at 39.86 MHz with power transfer efficiency of 47.2% and can also simultaneously radiate at 2.45 GHz with an impedance bandwidth of 10.8% and a gain of -15.71 dBi in the desired direction. Furthermore, sensitivity analyses are carried out with the help of experiment and simulation. The results reveal that the system has strong tolerance to the nonideal conditions. Additionally, the specific absorption rate distribution is evaluated in the light of strict IEEE standards. The results reveal that the implantable structure can receive up to 115 mW power from an external transmitter and radiate 6.4 dB.m of power safely. PMID- 29570058 TI - A Five-Tissue-Layer Human Body Communication Circuit Model Tunable to Individual Characteristics. AB - Human body communication (HBC) has several advantages over traditional wireless communications due to the high conductivity of human body. An accurate body channel model plays a vital role in optimizing the performance and power of HBC transceivers. In this paper, we present a body channel model with three distinct features. First, it takes into account all five body tissue layers resulting better accuracy; second, it adapts to different individuals with the proposed layer thickness estimation technique; third, it counts in the variation of backward coupling capacitance versus different postures. These new features significantly improve the model accuracy. Measurement results show that the proposed model achieves a maximum error of 2.21% in path loss for different human subjects. PMID- 29570057 TI - Vital Sign Monitoring Through the Back Using an UWB Impulse Radar With Body Coupled Antennas. AB - Radar devices can be used in nonintrusive situations to monitor vital sign, through clothes or behind walls. By detecting and extracting body motion linked to physiological activity, accurate simultaneous estimations of both heart rate (HR) and respiration rate (RR) is possible. However, most research to date has focused on front monitoring of superficial motion of the chest. In this paper, body penetration of electromagnetic (EM) wave is investigated to perform back monitoring of human subjects. Using body-coupled antennas and an ultra-wideband (UWB) pulsed radar, in-body monitoring of lungs and heart motion was achieved. An optimised location of measurement in the back of a subject is presented, to enhance signal-to-noise ratio and limit attenuation of reflected radar signals. Phase-based detection techniques are then investigated for back measurements of vital sign, in conjunction with frequency estimation methods that reduce the impact of parasite signals. Finally, an algorithm combining these techniques is presented to allow robust and real-time estimation of both HR and RR. Static and dynamic tests were conducted, and demonstrated the possibility of using this sensor in future health monitoring systems, especially in the form of a smart car seat for driver monitoring. PMID- 29570059 TI - An Extreme Learning Machine-Based Neuromorphic Tactile Sensing System for Texture Recognition. AB - Despite significant advances in computational algorithms and development of tactile sensors, artificial tactile sensing is strikingly less efficient and capable than the human tactile perception. Inspired by efficiency of biological systems, we aim to develop a neuromorphic system for tactile pattern recognition. We particularly target texture recognition as it is one of the most necessary and challenging tasks for artificial sensory systems. Our system consists of a piezoresistive fabric material as the sensor to emulate skin, an interface that produces spike patterns to mimic neural signals from mechanoreceptors, and an extreme learning machine (ELM) chip to analyze spiking activity. Benefiting from intrinsic advantages of biologically inspired event-driven systems and massively parallel and energy-efficient processing capabilities of the ELM chip, the proposed architecture offers a fast and energy-efficient alternative for processing tactile information. Moreover, it provides the opportunity for the development of low-cost tactile modules for large-area applications by integration of sensors and processing circuits. We demonstrate the recognition capability of our system in a texture discrimination task, where it achieves a classification accuracy of 92% for categorization of ten graded textures. Our results confirm that there exists a tradeoff between response time and classification accuracy (and information transfer rate). A faster decision can be achieved at early time steps or by using a shorter time window. This, however, results in deterioration of the classification accuracy and information transfer rate. We further observe that there exists a tradeoff between the classification accuracy and the input spike rate (and thus energy consumption). Our work substantiates the importance of development of efficient sparse codes for encoding sensory data to improve the energy efficiency. These results have a significance for a wide range of wearable, robotic, prosthetic, and industrial applications. PMID- 29570061 TI - High-Voltage, Multiphasic, Nanosecond Pulses to Modulate Cellular Responses. AB - Nanosecond electric pulses are an effective power source in plasma medicine and biological stimulation, in which biophysical responses are governed by peak power and not energy. While uniphasic nanosecond pulse generators are widely available, the recent discovery that biological effects can be uniquely modulated by reversing the polarity of nanosecond duration pulses calls for the development of a multimodal pulse generator. This paper describes a method to generate nanosecond multiphasic pulses for biomedical use, and specifically demonstrates its ability to cancel or enhance cell swelling and blebbing. The generator consists of a series of the fundamental module, which includes a capacitor and a MOSFET switch. A positive or a negative phase pulse module can be produced based on how the switch is connected. Stacking the modules in series can increase the voltage up to 5 kV. Multiple stacks in parallel can create multiphase outputs. As each stack is independently controlled and charged, multiphasic pulses can be created to produce flexible and versatile pulse waveforms. The circuit topology can be used for high-frequency uniphasic or biphasic nanosecond burst pulse production, creating numerous opportunities for the generator in electroporation applications, tissue ablation, wound healing, and nonthermal plasma generation. PMID- 29570060 TI - A Real-Time Reconfigurable Multichip Architecture for Large-Scale Biophysically Accurate Neuron Simulation. AB - Simulation of brain neurons in real-time using biophysically meaningful models is a prerequisite for comprehensive understanding of how neurons process information and communicate with each other, in effect efficiently complementing in-vivo experiments. State-of-the-art neuron simulators are, however, capable of simulating at most few tens/hundreds of biophysically accurate neurons in real time due to the exponential growth in the interneuron communication costs with the number of simulated neurons. In this paper, we propose a real-time, reconfigurable, multichip system architecture based on localized communication, which effectively reduces the communication cost to a linear growth. All parts of the system are generated automatically, based on the neuron connectivity scheme. Experimental results indicate that the proposed system architecture allows the capacity of over 3000 to 19 200 (depending on the connectivity scheme) biophysically accurate neurons over multiple chips. PMID- 29570062 TI - Sub 100 nW Volatile Nano-Metal-Oxide Memristor as Synaptic-Like Encoder of Neuronal Spikes. AB - Advanced neural interfaces mediate a bioelectronic link between the nervous system and microelectronic devices, bearing great potential as innovative therapy for various diseases. Spikes from a large number of neurons are recorded leading to creation of big data that require online processing under most stringent conditions, such as minimal power dissipation and on-chip space occupancy. Here, we present a new concept where the inherent volatile properties of a nano-scale memristive device are used to detect and compress information on neural spikes as recorded by a multielectrode array. Simultaneously, and similarly to a biological synapse, information on spike amplitude and frequency is transduced in metastable resistive state transitions of the device, which is inherently capable of self resetting and of continuous encoding of spiking activity. Furthermore, operating the memristor in a very high resistive state range reduces its average in operando power dissipation to less than 100 nW, demonstrating the potential to build highly scalable, yet energy-efficient on-node processors for advanced neural interfaces. PMID- 29570063 TI - A Digitally Programmable Cytomorphic Chip for Simulation of Arbitrary Biochemical Reaction Networks. AB - Prior work has shown that compact analog circuits can faithfully represent and model fundamental biomolecular circuits via efficient log-domain cytomorphic transistor equivalents. Such circuits have emphasized basis functions that are dominant in genetic transcription and translation networks and deoxyribonucleic acid (DNA)-protein binding. Here, we report a system featuring digitally programmable 0.35 MUm BiCMOS analog cytomorphic chips that enable arbitrary biochemical reaction networks to be exactly represented thus enabling compact and easy composition of protein networks as well. Since all biomolecular networks can be represented as chemical reaction networks, our protein networks also include the former genetic network circuits as a special case. The cytomorphic analog protein circuits use one fundamental association-dissociation-degradation building-block circuit that can be configured digitally to exactly represent any zeroth-, first-, and second-order reaction including loading, dynamics, nonlinearity, and interactions with other building-block circuits. To address a divergence issue caused by random variations in chip fabrication processes, we propose a unique way of performing computation based on total variables and conservation laws, which we instantiate at both the circuit and network levels. Thus, scalable systems that operate with finite error over infinite time can be built. We show how the building-block circuits can be composed to form various network topologies, such as cascade, fan-out, fan-in, loop, dimerization, or arbitrary networks using total variables. We demonstrate results from a system that combines interacting cytomorphic chips to simulate a cancer pathway and a glycolysis pathway. Both simulations are consistent with conventional software simulations. Our highly parallel digitally programmable analog cytomorphic systems can lead to a useful design, analysis, and simulation tool for studying arbitrary large-scale biological networks in systems and synthetic biology. PMID- 29570064 TI - Fast and Precise Emulation of Stochastic Biochemical Reaction Networks With Amplified Thermal Noise in Silicon Chips. AB - The analysis and simulation of complex interacting biochemical reaction pathways in cells is important in all of systems biology and medicine. Yet, the dynamics of even a modest number of noisy or stochastic coupled biochemical reactions is extremely time consuming to simulate. In large part, this is because of the expensive cost of random number and Poisson process generation and the presence of stiff, coupled, nonlinear differential equations. Here, we demonstrate that we can amplify inherent thermal noise in chips to emulate randomness physically, thus alleviating these costs significantly. Concurrently, molecular flux in thermodynamic biochemical reactions maps to thermodynamic electronic current in a transistor such that stiff nonlinear biochemical differential equations are emulated exactly in compact, digitally programmable, highly parallel analog "cytomorphic" transistor circuits. For even small-scale systems involving just 80 stochastic reactions, our 0.35-MUm BiCMOS chips yield a 311* speedup in the simulation time of Gillespie's stochastic algorithm over COPASI, a fast biochemical-reaction software simulator that is widely used in computational biology; they yield a 15 500* speedup over equivalent MATLAB stochastic simulations. The chip emulation results are consistent with these software simulations over a large range of signal-to-noise ratios. Most importantly, our physical emulation of Poisson chemical dynamics does not involve any inherently sequential processes and updates such that, unlike prior exact simulation approaches, they are parallelizable, asynchronous, and enable even more speedup for larger-size networks. PMID- 29570065 TI - A Scalable ISFET Sensing and Memory Array With Sensor Auto-Calibration for On Chip Real-Time DNA Detection. AB - This paper presents a novel CMOS-based system-on-chip with a 78 56 ion-sensitive field-effect transistor array using in-pixel quantization and compensation of sensor nonidealities. The pixel integrates sensing circuitry and memory cells to encode the ion concentration in time and store a calibration value per pixel. Temperature sensing pixels spread throughout the array allow temperature monitoring during the reaction. We describe the integration of the array as part of a lab-on-chip cartridge that plugs into a motherboard for power management, biasing, data acquisition, and temperature regulation. This forms a robust ion detection platform, which is demonstrated as a pH sensing system. We show that our calibration is able to perform readout with a linear spread of 0.3% and that the system exhibits a high pH sensitivity of 3.2 /pH. The complete system is shown to perform on-chip real-time DNA amplification and detection of lambda phage DNA by loop-mediated isothermal amplification. PMID- 29570066 TI - A High-Sensitivity Potentiometric 65-nm CMOS ISFET Sensor for Rapid E. coli Screening. AB - Foodborne bacteria, inducing outbreaks of infection or poisoning, have posed great threats to food safety. Potentiometric sensors can identify bacteria levels in food by measuring medium's pH changes. However, most of these sensors face the limitation of low sensitivity and high cost. In this paper, we developed a high sensitivity ion-sensitive field-effect transistor sensor. It is small sized, cost efficient, and can be massively fabricated in a standard 65-nm complementary metal-oxide-semiconductor process. A subthreshold pH-to-time-to-voltage conversion scheme was proposed to improve the sensitivity. Furthermore, design parameters, such as chemical sensing area, transistor size, and discharging time, were optimized to enhance the performance. The intrinsic sensitivity of passivation membrane was calculated as 33.2 mV/pH. It was amplified to 123.8 mV/pH with a 0.01-pH resolution, which greatly exceeded 6.3 mV/pH observed in a traditional source-follower based readout structure. The sensing system was applied to Escherichia coli (E. coli) detection with densities ranging from 14 to 140 cfu/mL. Compared to the conventional direct plate counting method (24 h), more efficient sixfold smaller screening time (4 h) was achieved to differentiate samples' E. coli levels. The demonstrated portable, time-saving, and low-cost prescreen system has great potential for food safety detection.

AB - The integration of biosensors, microfluidics, and CMOS instrumentation provides a compact lab-on-CMOS microsystem well suited for high throughput measurement. This paper describes a new epoxy chip-in-carrier integration process and two planar metalization techniques for lab-on-CMOS that enable on-CMOS electrochemical measurement with multichannel microfluidics. Several design approaches with different fabrication steps and materials were experimentally analyzed to identify an ideal process that can achieve desired capability with high yield and low material and tool cost. On-chip electrochemical measurements of the integrated assembly were performed to verify the functionality of the chip-in carrier packaging and its capability for microfluidic integration. The newly developed CMOS-compatible epoxy chip-in-carrier process paves the way for full implementation of many lab-on-CMOS applications with CMOS ICs as core electronic instruments. PMID- 29570069 TI - A Two-Wired Ultra-High Input Impedance Active Electrode. AB - This paper presents a novel two-wired active electrode that achieves ultrahigh input impedance using power supply bootstrapping. The proposed circuit reduces the input capacitance of a buffer amplifier while enabling measurements using leads with only two wires, providing a low-complexity and low-cost solution for interference rejection and artifact reduction in dc-coupled dry-contact biopotential measurements. An implemented prototype shows that, even using standard operational amplifiers, an input capacitance as low as 71 fF can be obtained, maintaining a high impedance in a 0-1 kHz bandwidth, sufficient for ECG, EEG, and EMG measurements. The circuit has a simple and easily replicable implementation that requires no individual adjustment. A common mode rejection ratio (CMRR) above 103 dB at 50 Hz was achieved and the increased rejection to interference due to the potential divider effect was experimentally tested maintaining a 92-dB CMRR at 50 Hz with a 1.2-M source impedance unbalance. ECG measurements were conducted to validate the active electrode against a traditional alternative, and a test with dry-contact EEG electrodes was successfully conducted. Although the proposed circuit is intended to acquire superficial electrophysiological signals using dry electrodes, it can be used for measurement from other high-impedance sources, such as micropipette electrodes. PMID- 29570068 TI - Fully Automatic Three-Dimensional Ultrasound Imaging Based on Conventional B Scan. AB - Robotic ultrasound systems have turned into clinical use over the past few decades, increasing precision and quality of medical operations. In this paper, we propose a fully automatic scanning system for three-dimensional (3-D) ultrasound imaging. A depth camera was first used to obtain the depth data and color data of the tissue surface. Based on the depth image, the 3-D contour of the tissue was rendered and the scan path of ultrasound probe was automatically planned. Following the scan path, a 3-D translating device drove the probe to move on the tissue surface. Simultaneously, the B-scans and their positional information were recorded for subsequent volume reconstruction. In order to stop the scanning process when the pressure on the skin exceeded a preset threshold, two force sensors were attached to the front side of the probe for force measurement. In vitro and in vivo experiments were conducted for assessing the performance of the proposed system. Quantitative results show that the error of volume measurement was less than 1%, indicating that the system is capable of automatic ultrasound scanning and 3-D imaging. It is expected that the proposed system can be well used in clinical practices. PMID- 29570070 TI - A Unified Mathematical Model for Nano-Liposomal Drug Delivery to Solid Tumors. AB - Nanoparticles, such as liposomes, allow more targeted drug delivery for improved efficacy and/or reduced toxicity in both passive (e.g., Doxil) or active [e.g., thermo-sensitive liposomes (TSL)] release forms compared with unencapsulated drugs (i.e., conventional chemotherapy). Optimization and evaluation of these different drug delivery systems are experimentally challenging because of varying tissue parameters as well as limited avaiability of experimental data. Here, we present a novel unified mathematical model that can simulate various liposomal drug delivery systems and unencapsulated drugs with a single set of equations. We use this model to evaluate the chemotherapy performance of free Doxorubicin (as drug), as well as various liposomal drug delivery systems: 1) passive liposomes (Doxil) and 2) active-triggered TSL with either intravascular (TSLi) or extravascular (TSLe)-triggered release. Furthermore, we implemented a more accurate expression to consider incomplete liposomal drug release. The proposed model matches experimental in vivo results in terms of maximum drug concentration in tumor. The simulations predict better overall performance for all liposomal delivery systems than free Dox. TSLe is shown to be more efficient for less permeable and perfused tumors than other systems. The optimal release rate is lower for TSLe and Doxil than TSLi. The performance of free DOX changes a little for varying tumor characteristics such as perfusion and permeability. PMID- 29570071 TI - Detection of Significant Copy Number Variations From Multiple Samples in Next Generation Sequencing Data. AB - Analyzing copy number variations (CNVs) from next-generation sequencing (NGS) data has become a common approach to detect disease susceptibility genes. The main challenge is how to utilize the NGS data with limited coverage depth to detect significant CNVs. Here, we introduce a new statistical method, the derivative of correlation coefficient (DCC), to detect significant CNVs that recurrently occur in multiple samples using read depth signals. We use a sliding window to calculate a correlation coefficient for each genome bin, and compute corresponding derivatives by fitting curves to the correlation coefficient. Then, the detection of significant CNVs was transformed into a problem of detecting significant derivatives reflecting genome breakpoints that can be solved using statistical hypothesis testing. We tested and compared the performance of DCC against several peer methods using a large number of simulation data sets, and validated DCC using several real sequencing data sets derived from the European Genome-Phenome archive, DNA Data Bank of Japan, and the 1000 Genomes Project. Experimental results suggest that DCC is an effective approach for identifying CNVs, outperforming peer methods in the terms of detection power and accuracy. DCC can be used to detect significant or recurrent CNVs in various NGS data sets, thus providing useful information to study genomic mutations and find disease susceptibility genes.

AB - Current studies on modulation and detection schemes in molecular communication mainly focus on the scenarios with static transmitters and receivers. However, mobile molecular communication is needed in many envisioned applications, such as target tracking and drug delivery. Until now, investigations about mobile molecular communication have been limited. In this paper, a static transmitter and a mobile bacterium-based receiver performing random walk are considered. In this mobile scenario, the channel impulse response changes due to the dynamic change of the distance between the transmitter and the receiver. Detection schemes based on fixed distance fail in signal detection in such a scenario. Furthermore, the intersymbol interference (ISI) effect becomes more complex due to the dynamic character of the signal which makes the estimation and mitigation of the ISI even more difficult. In this paper, an adaptive ISI mitigation method and two adaptive detection schemes are proposed for this mobile scenario. In the proposed scheme, adaptive ISI mitigation, estimation of dynamic distance, and the corresponding impulse response reconstruction are performed in each symbol interval. Based on the dynamic channel impulse response in each interval, two adaptive detection schemes, concentration-based adaptive threshold detection and peak-time-based adaptive detection, are proposed for signal detection. Simulations demonstrate that the ISI effect is significantly reduced and the adaptive detection schemes are reliable and robust for mobile molecular communication.

PMID- 29570074 TI - Maximum Likelihood Detection With Ligand Receptors for Diffusion-Based Molecular Communications in Internet of Bio-Nano Things. AB - Molecular Communication (MC) is a bio-inspired communication technique that uses molecules as a method of information transfer among nanoscale devices. MC receiver is an essential component having profound impact on the communication system performance. However, the interaction of the receiver with information bearing molecules has been usually oversimplified in modeling the reception process and developing signal detection techniques. In this paper, we focus on the signal detection problem of MC receivers employing receptor molecules to infer the transmitted messages encoded into the concentration of molecules, i.e., ligands. Exploiting the observable characteristics of ligand-receptor binding reaction, we first introduce a Maximum Likelihood (ML) detection method based on instantaneous receptor occupation ratio, as aligned with the current MC literature. Then, we propose a novel ML detection technique, which exploits the amount of time the receptors stay unbound in an observation time window. A comprehensive analysis is carried out to compare the performance of the detectors in terms of bit error probability. In evaluating the detection performance, emphasis is given to the receptor saturation problem resulting from the accumulation of messenger molecules at the receiver as a consequence of intersymbol interference. The results reveal that detection based on receptor unbound time is quite reliable even in saturation, whereas the reliability of detection based on receptor occupation ratio substantially decreases as the receiver gets saturated. Finally, we also discuss the potential methods of implementing the detectors.

AB - In this paper, we have developed a framework for detection of protein-protein interactions (PPI) between Hepatitis-C virus (HCV) and human proteins based on PPI and gene ontology based information of the HCV infected proteins. First, a bipartite interaction network is formed between HCV proteins and human host proteins. Next, we have analyzed different topological properties of the interaction network and observed that degree of HCV-interacting proteins is significantly higher than non-interacting host proteins. We have also observed that the HCV interacted protein pairs are functionally similar with each other than the non-interacting pairs. Following the observations, we have applied an inference mechanism to predict novel interactions between HCV and human protein. The inference mechanism is based on partitioning the network formed by HCV interacted human proteins and their first neighbors in dense and functionally similar groups using a PPI network clustering algorithm. The groups are then analyzed to predict PPIs. The predicted interaction pairs are validated using literature search in PUBMED. Experimental evidence of over 50% of the predicted pairs are found in existing literatures by searching PUBMED. A Gene Ontology and pathway based analysis is also carried out to validate the identified modules biologically. PMID- 29570076 TI - Pinpoint Delivery of Molecules by Using Electron Beam Addressing Virtual Cathode Display. AB - Electroporation, a physical transfection method to introduce genomic molecules in selective living cells, could be implemented by microelectrode devices. A local electric field generated by a finer electrode can induces cytomembrane poration in the electrode vicinity. To employ fine, high-speed scanning electrodes, we developed a fine virtual cathode pattern, which was generated on a cell adhesive surface of 100-nm-thick SiN membrane by inverted-electron beam lithography. The SiN membrane works as both a vacuum barrier and the display screen of the virtual cathode. The kinetic energy of the incident primary electrons to the SiN membrane was completely blocked, whereas negative charges and leaking electric current appeared on the surface of the dielectric SiN membrane within a region of 100 nm. Locally controlled transmembrane molecular delivery was demonstrated on adhered C2C12 myoblast cells in a culturing medium with fluorescent dye propidium iodide (PI). Increasing fluorescence of pre-diluted PI indicated local poration and transmembrane inflow at the virtual cathode position, as well as intracellular diffusion. The transmembrane inflows depended on beam duration time and acceleration voltage. At the post-molecular delivery, a slight decrease in intracellular PI fluorescence intensity indicates membrane recovery from the poration. Cell viability was confirmed by time-lapse cell imaging of post exposure cell migration.

AB - Beta amyloid ( ) peptide, which is a common neuropathological hallmark deposit in the brain of patients with Alzheimer's disease, typically comprises 39-43 amino acid residues. peptides exist as isoforms of and with various lengths. In this research, atomic force microscopy (AFM) was applied to investigate aggregations in Hank's Balanced Salt Solution. Toxic effect of oligomer was investigated in live SH-SY5Y neuroblastoma cells by characterizing cell morphology and cell mechanics using high-resolution AFM scanning. oligomer-induced cytoskeleton reorganization was also observed under confocal microscopy, and it can account for reduction in Young's modulus of cells. Meanwhile, phosphorylation of tau increased after oligomer treatment, possibly resulting in microtubule disassembly. This paper demonstrates the linkage between cellular mechanical changes and neurodegeneration mediated by . The method used implies promising applications of real-time monitoring of cellular mechanical properties given the toxic effects of on living neuronal cells. PMID- 29570078 TI - Axonal Channel Capacity in Neuro-Spike Communication. AB - Novel nano-scale communication techniques are inspired by biological systems. Neuro-spike communication is an example of this communication paradigm which transfers vital information about external and internal conditions of the body through the nervous system. The analysis of this communication paradigm is beneficial to exploit in the artificial neural systems where nano-machines are linked to neurons to treat the neurodegenerative diseases. In these networks, nano-machines are used to replace the damaged segments of the nervous system and they exactly behave like biological entities. In neuro-spike communication, neurons / nano-machines exploit the electro-chemical spikes and molecular communication to transfer information. This communication paradigm can be divided into three main parts, namely the axonal pathway, the synaptic transmission, and the spike generation. In this paper, we focus on the axonal transmission part as a separate channel since the capacity of the axonal pathway has a significant effect on the capacity of neuro-spike communication channel. In thinner axons, the capacity of this part is the bottleneck of the neuro-spike communication channel capacity. Hence, we investigate the restricting factors of the axonal transmission which limit its capacity. We derive the capacity of single-input single-output and multiple-input single-output (MISO) axonal channels. In the MISO case, we investigate the effect of the correlation among inputs on the channel capacity. Moreover, we derive a closed form description for the optimum value of the input spike rate to maximize the capacity of the axonal channel when the information is encoded by firing rate of neurons / nano-machines. PMID- 29570079 TI - Shannon Meets Fick on the Microfluidic Channel: Diffusion Limit to Sum Broadcast Capacity for Molecular Communication. AB - Molecular communication (MC) over a microfluidic channel with flow is investigated based on Shannon's channel capacity theorem and Fick's laws of diffusion. Specifically, the sum capacity for MC between a single transmitter and multiple receivers (broadcast MC) is studied. The transmitter communicates by using different types of signaling molecules with each receiver over the microfluidic channel. The transmitted molecules propagate through microfluidic channel until reaching the corresponding receiver. Although the use of different types of molecules provides orthogonal signaling, the sum broadcast capacity may not scale with the number of the receivers due to physics of the propagation (interplay between convection and diffusion based on distance). In this paper, the performance of broadcast MC on a microfluidic chip is characterized by studying the physical geometry of the microfluidic channel and leveraging the information theory. The convergence of the sum capacity for microfluidic broadcast channel is analytically investigated based on the physical system parameters with respect to the increasing number of molecular receivers. The analysis presented here can be useful to predict the achievable information rate in microfluidic interconnects for the biochemical computation and microfluidic multi-sample assays.

AB - In this paper, we propose a novel matching based tracker by investigating the relationship between template matching and the recent popular correlation filter based trackers (CFTs). Compared to the correlation operation in CFTs, a sophisticated similarity metric termed mutual buddies similarity is proposed to exploit the relationship of multiple reciprocal nearest neighbors for target matching. By doing so, our tracker obtains powerful discriminative ability on distinguishing target and background as demonstrated by both empirical and theoretical analyses. Besides, instead of utilizing single template with the improper updating scheme in CFTs, we design a novel online template updating strategy named memory, which aims to select a certain amount of representative and reliable tracking results in history to construct the current stable and expressive template set. This scheme is beneficial for the proposed tracker to comprehensively understand the target appearance variations, recall some stable results. Both qualitative and quantitative evaluations on two benchmarks suggest that the proposed tracking method performs favorably against some recently developed CFTs and other competitive trackers. PMID- 29570082 TI - An Analytic Gabor Feedforward Network for Single-Sample and Pose-Invariant Face Recognition. AB - Gabor magnitude is known to be among the most discriminative representations for face images due to its space- frequency co-localization property. However, such property causes adverse effects even when the images are acquired under moderate head pose variations. To address this pose sensitivity issue and other moderate imaging variations, we propose an analytic Gabor feedforward network which can absorb such moderate changes. Essentially, the network works directly on the raw face images and produces directionally projected Gabor magnitude features at the hidden layer. Subsequently, several sets of magnitude features obtained from various orientations and scales are fused at the output layer for final classification decision. The network model is analytically trained using a single sample per identity. The obtained solution is globally optimal with respect to the classification total error rate. Our empirical experiments conducted on five face data sets (six subsets) from the public domain show encouraging results in terms of identification accuracy and computational efficiency. PMID- 29570083 TI - Camera-Aware Multi-Resolution Analysis for Raw Image Sensor Data Compression. AB - We propose novel lossless and lossy compression schemes for color filter array (CFA) sampled images based on the Camera-A ware Multi-Resolution Analysis, or CAMRA. Specifically, by CAMRA we refer to modifications that we make to wavelet transform of CFA sampled images in order to achieve a very high degree of decorrelation at the finest scale wavelet coefficients; and a series of color processing steps applied to the coarse scale wavelet coefficients, aimed at limiting the propagation of lossy compression errors through the subsequent camera processing pipeline. We validated our theoretical analysis and the performance of the proposed compression schemes using the images of natural scenes captured in a raw format. The experimental results verify that our proposed methods improve coding efficiency relative to the standard and the state of-the-art compression schemes for CFA sampled images. PMID- 29570084 TI - Unsupervised Uncertainty Estimation Using Spatiotemporal Cues in Video Saliency Detection. AB - In this paper, we address the problem of quantifying the reliability of computational saliency for videos, which can be used to improve saliency-based video processing algorithms and enable more reliable performance and objective risk assessment of saliency-based video processing applications. Our approach to quantify such reliability is twofold. First, we explore spatial correlations in both the saliency map and the eye-fixation map. Then, we learn the spatiotemporal correlations that define a reliable saliency map. We first study spatiotemporal eye-fixation data from the public CRCNS data set and investigate a common feature in human visual attention, which dictates a correlation in saliency between a pixel and its direct neighbors. Based on the study, we then develop an algorithm that estimates a pixel-wise uncertainty map that reflects our supposed confidence in the associated computational saliency map by relating a pixel's saliency to the saliency of its direct neighbors. To estimate such uncertainties, we measure the divergence of a pixel, in a saliency map, from its local neighborhood. In addition, we propose a systematic procedure to evaluate uncertainty estimation performance by explicitly computing uncertainty ground truth as a function of a given saliency map and eye fixations of human subjects. In our experiments, we explore multiple definitions of locality and neighborhoods in spatiotemporal video signals. In addition, we examine the relationship between the parameters of our proposed algorithm and the content of the videos. The proposed algorithm is unsupervised, making it more suitable for generalization to most natural videos. Also, it is computationally efficient and flexible for customization to specific video content. Experiments using three publicly available video data sets show that the proposed algorithm outperforms state-of-the-art uncertainty estimation methods with improvement in accuracy up to 63% and offers efficiency and flexibility that make it more useful in practical situations. PMID- 29570085 TI - Structure-Revealing Low-Light Image Enhancement Via Robust Retinex Model. AB - Low-light image enhancement methods based on classic Retinex model attempt to manipulate the estimated illumination and to project it back to the corresponding reflectance. However, the model does not consider the noise, which inevitably exists in images captured in low-light conditions. In this paper, we propose the robust Retinex model, which additionally considers a noise map compared with the conventional Retinex model, to improve the performance of enhancing low-light images accompanied by intensive noise. Based on the robust Retinex model, we present an optimization function that includes novel regularization terms for the illumination and reflectance. Specifically, we use norm to constrain the piece wise smoothness of the illumination, adopt a fidelity term for gradients of the reflectance to reveal the structure details in low-light images, and make the first attempt to estimate a noise map out of the robust Retinex model. To effectively solve the optimization problem, we provide an augmented Lagrange multiplier based alternating direction minimization algorithm without logarithmic transformation. Experimental results demonstrate the effectiveness of the proposed method in low-light image enhancement. In addition, the proposed method can be generalized to handle a series of similar problems, such as the image enhancement for underwater or remote sensing and in hazy or dusty conditions. PMID- 29570086 TI - Learning Clip Representations for Skeleton-Based 3D Action Recognition. AB - This paper presents a new representation of skeleton sequences for 3D action recognition. Existing methods based on hand-crafted features or recurrent neural networks cannot adequately capture the complex spatial structures and the long term temporal dynamics of the skeleton sequences, which are very important to recognize the actions. In this paper, we propose to transform each channel of the 3D coordinates of a skeleton sequence into a clip. Each frame of the generated clip represents the temporal information of the entire skeleton sequence and one particular spatial relationship between the skeleton joints. The entire clip incorporates multiple frames with different spatial relationships, which provide useful spatial structural information of the human skeleton. We also propose a multitask convolutional neural network (MTCNN) to learn the generated clips for action recognition. The proposed MTCNN processes all the frames of the generated clips in parallel to explore the spatial and temporal information of the skeleton sequences. The proposed method has been extensively tested on six challenging benchmark datasets. Experimental results consistently demonstrate the superiority of the proposed clip representation and the feature learning method for 3D action recognition compared to the existing techniques. PMID- 29570087 TI - Generalization of the Dark Channel Prior for Single Image Restoration. AB - Images degraded by light scattering and absorption, such as hazy, sandstorm, and underwater images, often suffer color distortion and low contrast because of light traveling through turbid media. In order to enhance and restore such images, we first estimate ambient light using the depth-dependent color change. Then, via calculating the difference between the observed intensity and the ambient light, which we call the scene ambient light differential, scene transmission can be estimated. Additionally, adaptive color correction is incorporated into the image formation model (IFM) for removing color casts while restoring contrast. Experimental results on various degraded images demonstrate the new method outperforms other IFM-based methods subjectively and objectively. Our approach can be interpreted as a generalization of the common dark channel prior (DCP) approach to image restoration, and our method reduces to several DCP variants for different special cases of ambient lighting and turbid medium conditions. PMID- 29570088 TI - Deep Action Parsing in Videos With Large-Scale Synthesized Data. AB - Action parsing in videos with complex scenes is an interesting but challenging task in computer vision. In this paper, we propose a generic 3D convolutional neural network in a multi-task learning manner for effective Deep Action Parsing (DAP3D-Net) in videos. Particularly, in the training phase, action localization, classification, and attributes learning can be jointly optimized on our appearance-motion data via DAP3D-Net. For an upcoming test video, we can describe each individual action in the video simultaneously as: Where the action occurs, What the action is, and How the action is performed. To well demonstrate the effectiveness of the proposed DAP3D-Net, we also contribute a new Numerous category Aligned Synthetic Action data set, i.e., NASA, which consists of 200 000 action clips of over 300 categories and with 33 pre-defined action attributes in two hierarchical levels (i.e., low-level attributes of basic body part movements and high-level attributes related to action motion). We learn DAP3D-Net using the NASA data set and then evaluate it on our collected Human Action Understanding data set and the public THUMOS data set. Experimental results show that our approach can accurately localize, categorize, and describe multiple actions in realistic videos. PMID- 29570089 TI - Content-Adaptive Superpixel Segmentation. AB - Superpixel segmentation targets at grouping pixels in an image into atomic regions whose boundaries align well with the natural object boundaries. This paper first proposes a new feature representation for superpixel segmentation that holistically embraces color, contour, texture, and spatial features. Then, we introduce a clustering-based discriminability measure to iteratively evaluate the importance of different features. Integrating the feature representation and the discriminability measure, we propose a novel content-adaptive superpixel (CAS) segmentation algorithm. CAS is able to automatically and iteratively adjust the weights of different features to fit various properties of image instances. Experiments on several challenging datasets demonstrate that the proposed CAS outperforms the state-of-the-art methods and has a low computational cost. PMID- 29570090 TI - Shaping up synthetic cells. AB - How do the cells in our body reconfigure their shape to achieve complex tasks like migration and mitosis, yet maintain their shape in response to forces exerted by, for instance, blood flow and muscle action? Cell shape control is defined by a delicate mechanical balance between active force generation and passive material properties of the plasma membrane and the cytoskeleton. The cytoskeleton forms a space-spanning fibrous network comprising three subsystems: actin, microtubules and intermediate filaments. Bottom-up reconstitution of minimal synthetic cells where these cytoskeletal subsystems are encapsulated inside a lipid vesicle provides a powerful avenue to dissect the force balance that governs cell shape control. Although encapsulation is technically demanding, a steady stream of advances in this technique has made the reconstitution of shape-changing minimal cells increasingly feasible. In this topical review we provide a route-map of the recent advances in cytoskeletal encapsulation techniques and outline recent reports that demonstrate shape change phenomena in simple biomimetic vesicle systems. We end with an outlook toward the next steps required to achieve more complex shape changes with the ultimate aim of building a fully functional synthetic cell with the capability to autonomously grow, divide and move. PMID- 29570091 TI - Experimental validation of predicted cancer genes using FRET. AB - Huge amounts of data are generated in genome wide experiments, designed to investigate diseases with complex genetic causes. Follow up of all potential leads produced by such experiments is currently cost prohibitive and time consuming. Gene prioritization tools alleviate these constraints by directing further experimental efforts towards the most promising candidate targets. Recently a gene prioritization tool called MaxLink was shown to outperform other widely used state-of-the-art prioritization tools in a large scale in silico benchmark. An experimental validation of predictions made by MaxLink has however been lacking. In this study we used Fluorescence Resonance Energy Transfer, an established experimental technique for detection of protein-protein interactions, to validate potential cancer genes predicted by MaxLink. Our results provide confidence in the use of MaxLink for selection of new targets in the battle with polygenic diseases. PMID- 29570092 TI - Facile preparation of surfactant-free Au NPs/RGO/Ni foam for degradation of 4 nitrophenol and detection of hydrogen peroxide. AB - The application of Au nanoparticles (Au NPs) often requires surface modification with chemical surfactants, which dramatically reduce the surface activity and increase the chemical contamination and cost of Au NPs. In this research, we have developed a novel Au NPs/reduced graphene oxide/Ni foam hybrid (Au NPs/RGO/NiF) by in situ reduction through ascorbic acid and replacement reaction. This method is green, facile and efficient. The Au NPs are free of chemical surfactants and are homogeneously distributed on the surface of the RGO/NiF. The as-prepared Au NPs/RGO/NiF hybrid is uniform, stable and exhibits not only a high reduction efficiency for the reduction of 4-nitrophenol with a catalytic kinetic constant of up to 0.46 min-1 (0.15 cm3 catalysis) but also a sensitive and selective detection of H2O2 with a detection limit of ~1.60 MUM. PMID- 29570094 TI - Dendrimer ligands-capped CH3NH3PbBr3 perovskite nanocrystals with delayed halide exchange and record stability against both moisture and water. AB - CH3NH3PbBr3 perovskite nanocrystals (NCs) suffer from poor stability because of their high sensitivity to environmental moisture and water. To solve this problem, previous works mainly focus on embedding perovskite NCs into water resistant matrix to form large composites (size of microns or larger). As an alternative solution without serious changing of NC size, enhancing the stability of perovskite NCs themselves by ligand engineering is rarely reported. In this work, we used hyperbranched polyamidoamine (PAMAM) dendrimers with two different generations (G0 and G4) to synthesize CH3NH3PbBr3 perovskite NCs with high photoluminescence (PL) quantum yields (QY) above 70% and a new record stability. A novel dendrimers generation-dependent stability of perovskite NCs was observed. The water-resistance time is 18 h (27 h) for perovskite NCs capped by G0 (G4) generation of PAMAM, which is 7 times (11 times) longer than that of traditional oleic acid-capped NCs. Similar PAMAM generation-related stability is also observed in moisture-resistance tests. The stability time against moisture is 500 h (800 h) for G0 (G4) generation of PAMAM-capped perovskite NCs, which is a new record stability time against moisture for CH3NH3PbBr3 perovskite NCs. In addition, our results also indicate that PAMAM ligands outside perovskite NCs can dramatically slow down the speed of halide exchange. Even for the mixture of perovskite NCs with two different halide composition, the original luminescence properties of PAMAM-capped perovskite NCs can retain after mixing. In view of slow halide exchange speed, excellent water and moisture stability, PAMAM dendrimers-capped perovskite NCs and their mixture are available as color conversion single layer in fabrication of light-emitting diodes (LED). PMID- 29570093 TI - Synthesis of highly stable cyanine-dye-doped silica nanoparticle for biological applications. AB - Cyanine dyes are widely used in biological labeling and imaging because of their narrow near infrared emission, good brightness and high flexibility in functionalization, which not only enables multiplex analysis and multi-color imaging, but also greatly reduces autofluorescence from biological matter and increases signal-to-noise ratio. Unfortunately, their poor chemical- and photo stability strongly limits their applications. The incorporation of cyanine dyes in silica nanoparticles provides a solution to the problem. On one hand, the incorporation of cyanine dyes in silica matrix can enhance their chemical- and photo-stability and increase brightness of the nanomaterials. On the other hand, silica matrix provides an optimized condition to host the dye, which helps to maintain their fluorescent properties during application. In addition, the well established silane technique provides numerous functionalities for diverse applications. However, commercially available cyanine dyes are not very stable at high alkaline conditions, which will gradually lose their fluorescence over time. Our results showed that cyanine dyes are very vulnerable in the reverse micelle system, in which they will lose their fluorescence in less than half an hour. The existence of surfactant could greatly promote degradation of cyanine dyes. Fluorescent silica nanoparticles cannot be obtained at the high alkaline condition with the existence of surfactant. In contrast, the cyanine dyes are relatively stable in Stober media. Owing to the fast formation of silica particles in Stober media, the exposure time of cyanine dye in alkaline solution was greatly reduced, and highly fluorescent particles with good morphology and size distribution could be obtained via Stober approach. However, the increasing water content in the Stober could reduce the stability of cyanine dyes, which should be avoided. This research here provides a clear guidance on how to successfully synthesize cyanine dye-doped silica nanoparticles with good morphology, size distribution, stability and brightness. PMID- 29570095 TI - Doped bottom-contact organic field-effect transistors. AB - The influence of doping on doped bottom-gate bottom-contact organic field-effect transistors (OFETs) is discussed. It is shown that the inclusion of a doped layer at the dielectric/organic semiconductor layer leads to a significant reduction in the contact resistances and a fine control of the threshold voltage. Through varying the thickness of the doped layer, a linear shift of threshold voltage V T from -3.1 to -0.22 V is observed for increasing thickness of doped layer. Meanwhile, the contact resistance at the source and drain electrode is reduced from 138.8 MOmega at V GS = -10 V for 3 nm to 0.3 MOmega for 7 nm thick doped layers. Furthermore, an increase of charge mobility is observed for increasing thickness of doped layer. Overall, it is shown that doping can minimize injection barriers in bottom-contact OFETs with channel lengths in the micro-meter regime, which has the potential to increase the performance of this technology further. PMID- 29570096 TI - Smart self-tightening surgical suture from a tough bio-based hyperbranched polyurethane/reduced carbon dot nanocomposite. AB - Design and fabrication of a smart bio-based polymeric material with potent biocompatibility and high performance still remain a challenge in the biomedical realm. In this context, a potential smart suture was fabricated from starch modified hyperbranched polyurethane (HPU) nanocomposites with different weight percentages of reduced carbon dots for the first time. The desired mechanical (tensile strength: 32.14 MPa, elongation at break: 1576% and toughness 439.28 MJ m-3) and thermal (286 degrees C) attributes of the suture were achieved with 2 wt% of reduced carbon dots in an HPU matrix. The non-contact self-tightening behavior was observed just within 15 s at body temperature of 37 degrees C +/- 1 degrees C with notable shape fixity (99.6%) and shape recovery (99.7%) effects. The nanocomposites displayed in vitro biodegradability and hemocompatibility. Low lactate dehydrogenase activity and minimal red blood cell lysis indicated the anti-thrombogenicity and anti-hemolytic properties of the nanocomposites. The suitability of the fabricated nanocomposites as a smart biomaterial was supported by the inherent biocompatibility as observed by the growth and proliferation of smooth muscle cells and endothelial cells. Furthermore, they exhibited minimal immunogenic response (TNF alpha release). Thus, the study paves the way to biodegradable HPU nanocomposites as advanced non-contact triggered rapid self tightening surgical sutures for biomedical applications. PMID- 29570097 TI - Cytotoxicity of titanium carbonitride coatings for prostodontic alloys with different amounts of carbon and nitrogen. AB - The aim of our work was to examine the cytotoxicity of NiCr alloys coated with Ti(C,N) with different amounts of C and N in the layer on human gingival fibroblasts. Cells were cultured for 24 hours in the alloy extracts or on the surface of tested materials. The viability of the cells exposed to 1-, 3-, 5- and 7-day extracts did not change in comparison to the viability of cells cultured in a control medium assayed by an MTT test. Moreover, the flow cytometry analysis of fibroblasts cultured in direct contact with tested alloys revealed that all coatings except TiC did not induce apoptosis or necrosis. Interestingly, 24 hour fibroblast culture on alloys with Ti(C,N) coatings showed that the number of fibroblasts adhered to these alloys, evaluated by scanning electron microscope, increased with an increase in the content of nitrogen in the layer. The present study demonstrates that Ti(C,N) coatings were not cytotoxic and did not induce apoptosis in Ti(C,N) extracts, nor in direct contact with gingival fibroblasts, and can be considered for biomedical applications in the future. PMID- 29570098 TI - Exocytosis of gold nanoparticle and photosensitizer from cancer cells and their effects on photodynamic and photothermal processes. AB - We first illustrate the faster decrease of the photothermal (PT) effect with the delay time of laser treatment, in which the illumination of a 1064 nm laser effectively excites the localized surface plasmon (LSP) resonance of cell-up taken gold nanoring (NRI) linked with a photosensitizer (PS), when compared with the photodynamic (PD) effect produced by the illumination of a 660 nm laser for effective PS excitation. The measurement results of the metal contents of Au NRI and PS based on inductively coupled plasma mass spectroscopy and the PS fluorescence intensity based on flow cytometry show that the linkage of NRI and PS is rapidly broken for releasing PS through the effect of glutathione in lysosome after cell uptake. Meanwhile, NRI escapes from a cell with a high rate such that the PT effect decays fast while the released PS can stay inside a cell longer for producing a prolonged PD effect. The effective delivery of PS through the linkage with Au NRI for cell uptake and the advantageous effect of LSP resonance at a PS absorption wavelength on the PD process are also demonstrated.

PMID- 29570100 TI - Inhibition of anaplastic lymphoma kinase promotes apoptosis and suppresses proliferation in human hepatocellular carcinoma. AB - Our study was to examine the roles of crizotinib and ceritinib in hepatocellular carcinoma (HCC) cells and explore the possible mechanisms. MTT assay was employed to examine the proliferation of five HCC cell lines treated with various concentrations of crizotinib or ceritinib. HepG2 and HCCLM3 cells were incubated with 2 nmol/l ceritinib for 1 week, followed by crystal violet staining and cell counting. Protein amounts of t-ALK, p-ALK, t-AKT, p-AKT, t-ERK, p-ERK, Mcl-1, survivin, and XIAP in HepG2 cells under different culture conditions were evaluated by western blot. HepG2 and HCCLM3 cells were treated with vehicle or ceritinib and measured by flow cytometry apoptosis analysis with Annexin V/propidium iodide staining. MTT assay showed that both crizotinib and ceritinib suppressed the proliferation of various human HCC cells. Crystal violet staining analysis also indicated that ceritinib effectively inhibited human HCC cell proliferation. Western blot analysis indicated that both crizotinib and ceritinib inhibited ALK, AKT, and ERK phosphorylations. In addition, ceritinib reduced antiapoptotic gene expressions in HepG2 cells. Flow cytometry analysis indicated that ceritinib induced HepG2 and HCCLM3 cells apoptosis. ALK inhibitor exhibited antitumor effects by inhibiting ALK activation, repressing AKT and ERK pathways, and suppressing antiapoptotic gene expressions, which subsequently promoted apoptosis and suppressed HCC cell proliferations. PMID- 29570101 TI - Venous thromboembolic events in patients with lung cancer treated with cisplatin based versus carboplatin/nedaplatin-based chemotherapy. AB - An association between chemotherapy and venous thromboembolic events (VTEs) in patients with cancer is well established, with cisplatin (CDDP) being one of the most well-studied risk factors. However, whether CDDP is more strongly associated with occurrence of VTEs than carboplatin (CBDCA) or nedaplatin (CDGP) is controversial. Our purposes were to characterize patients with lung cancer and in hospital VTEs, identify risk factors associated with VTEs, and compare the risks associated with CDDP-based versus CBDCA/CDGP-based chemotherapy. We retrospectively identified patients with lung cancer who underwent platinum-based chemotherapy from April 2012 to March 2015 from a national inpatient database in Japan. We used multivariable logistic regression analysis to analyze associations between various factors, including chemotherapy regimens and VTE. Of 235 104 eligible patients, 675 (0.29%) had VTEs after receiving platinum-based chemotherapy while hospitalized. Multivariable analysis showed that age, activity of daily living index, and invasive medical procedures were significant risk factors for the occurrence of VTE. Furthermore, CDDP-based chemotherapy was associated with a higher rate of VTE than CBDCA/CDGP-based chemotherapy (adjusted odds ratio: 1.35; 95% confidence interval: 1.08-1.68; P<0.01). In conclusion, CDDP-based chemotherapy is a stronger risk factor for VTEs than CBDCA/CDGP-based chemotherapy in patients with lung cancer.

AB - INTRODUCTION: Over 25% of Persian Gulf War (PGW) veterans with Gulf War Illness (GWI) (chronic health symptoms of undetermined etiology) developed gastrointestinal (GI) (diarrhea and abdominal pain) and other somatic symptoms. OBJECTIVES: Our study objective was to determine if veterans with GWI and GI symptoms exhibit heightened patterns of somatic pain perception (hypersensitivity) across nociceptive stimuli modalities. METHODS: Participants were previously deployed GW Veterans with GWI and GI symptoms (n=53); veterans with GWI without GI symptom (n=47); and veteran controls (n=38). We determined pain thresholds for contact thermal, cold pressor, and ischemic stimuli. RESULTS: Veterans with GWI and GI symptoms showed lower pain thresholds (P<0.001) for each stimulus. There was also overlap of somatic hypersensitivities among veterans with GI symptoms with 20% having hypersensitivity to all 3 somatic stimuli. Veterans with GWI and GI symptoms also showed a significant correlation between mechanical visual analog scale abdominal pain ratings and heat pain threshold, cold pressor threshold, and ischemic pain threshold/tolerance. DISCUSSION: Our findings show that there is widespread somatic hypersensitivity in veterans with GWI/GI symptoms that is positively correlated with abdominal pain ratings. In addition, veterans with somatic hypersensitivity that overlap have the greatest number of extraintestinal symptoms. These findings may have a translational benefit: strategies for developing more effective therapeutic agents that can reduce and/or prevent somatic and GI symptoms in veterans deployed to future military conflicts. PMID- 29570103 TI - Invitation strategies and coverage in the population-based cancer screening programmes in the European Union. AB - The aim of this study was to describe the compliance of the population-based cancer screening programmes in the European Union Member States to the invitation strategies enumerated in the European Guidelines and the impact of such strategies on the invitational coverage. Experts in screening programme monitoring from the respective countries provided data. Coverage by invitation was calculated as the proportion of individuals in the target age range receiving a screening invitation over the total number of annualized eligible population. The invitation strategies of 30 breasts, 25 cervical and 27 colorectal national or regional population-based screening programmes are described. Individual mail invitations are sent by 28 breasts, 20 cervical and 25 colorectal screening programmes. Faecal occult blood test kits are sent by post in 17 of the colorectal cancer screening programmes. The majority of programmes claimed to have a population registry, although some use health insurance data as the database for sending invitations. At least 95% invitation coverage was reached by 16 breast, six cervical and five colorectal screening programmes. Majority of the programmes comply with the invitation strategies enumerated in the European guidelines, although there is still scope for improvements. Coverage by invitation is below the desirable level in many population-based cancer screening programmes in European Union. PMID- 29570104 TI - Serum uric acid and cancer mortality and incidence: a systematic review and meta analysis. AB - Elevated serum uric acid (SUA) is a marker of chronic inflammation and has been suggested to be associated with increased risk of cancer, but its antioxidant capacity would justify an anticancer effect. Previous meta-analyses did not include all available results. We conducted a systematic review of prospective studies on SUA level and risk of all cancers and specific cancers, a conducted a meta-analysis based on random-effects models for high versus low SUA level as well as for an increase in 1 mg/dl SUA. The relative risk of all cancers for high versus low SUA level was 1.11 (95% confidence interval: 0.94-1.27; 11 risk estimates); that for a mg/dl increase in SUA level was 1.03 (95% confidence interval: 0.99-1.07). Similar results were obtained for lung cancer (six risk estimates) and colon cancer (four risk estimates). Results for other cancers were sparse. Elevated SUA levels appear to be associated with a modest increase in overall cancer risk, although the combined risk estimate did not reach the formal level of statistical significance. Results for specific cancers were limited and mainly negative. PMID- 29570105 TI - Folate intake, serum folate, and risk of esophageal cancer: a systematic review and dose-response meta-analysis. AB - The dose-response relationship between folate and the risk of esophageal cancer (EC) is not clear. To further elucidate their relationships, we carried out a dose-response meta-analysis of folate intake, serum folate, and the risk of EC. PubMed, Embase, Web of Science, and China National Knowledge Infrastructure were searched for observational studies until September 2016. Then, we carried out a systematic review and dose-response meta-analysis using Stata 14.0 software. Subgroup analyses were further carried out according to study characteristics and adjustment confounders. A total of 23 studies with a total of 3886 patients were enrolled in this study. The pooled odds ratios for EC in the highest versus the lowest levels of folate intake and serum folate were 0.64 (0.54-0.76, P<0.001) and 0.45 (0.19-1.07, P=0.071), respectively. Dose-response meta-analyses were carried out to assess associations between folate intake, serum folate, and EC risk. When serum folate is 10 MUg/l higher than the lowest reference dosage (3.44 MUg/l), EC decreased risk with an increase in serum folate levels. When folate intake is 50 MUg/day higher than the lowest reference dosage (125.21 MUg/day), the EC risk is decreased with an increase in folate intake. Finally, the results support that folate can promote public health through decreasing EC risk in a certain dosage range; otherwise, the protective effects might be reduced.

PMID- 29570107 TI - Extensive Myocardial Calcification in Critically Ill Patients. AB - OBJECTIVES: To describe an unusual complication on extracorporeal membrane oxygenation. DATA SOURCES: Clinical observation. STUDY SELECTION: Case report. DATA EXTRACTION: Relevant clinical information. DATA SYNTHESIS: We report the cases of three young patients who developed extensive myocardial calcifications on prolonged extracorporeal membrane oxygenation support for severe acute respiratory distress syndrome with septic cardiomyopathy, postresuscitation cardiogenic shock, and septic shock complicating severe acute respiratory distress syndrome, respectively. Extensive myocardial calcifications were confirmed by echocardiography, CT, and cardiac biopsy. The combination of multiple factors, for example, prolonged hemodynamic failure, profound acidosis, high vasopressor doses, and renal failure, may lead to this unusual and severe complication. CONCLUSIONS: Intensivists should be aware of this rare but rapid complication on extracorporeal membrane oxygenation support that may directly impact outcome. The precise role of extracorporeal membrane oxygenation support in the timing and frequency of new-onset diffuse myocardial calcification deserves further investigation. PMID- 29570108 TI - Intra-operative lidocaine in the prevention of vomiting after elective tonsillectomy in children: A randomised controlled trial. AB - BACKGROUND: Postoperative vomiting (POV) is a frequent complication of tonsillectomy in children. In adult patients undergoing abdominal surgeries, the use of intravenous lidocaine infusion can prevent POV. OBJECTIVE: To evaluate the anti-emetic effect of an intravenous lidocaine infusion used as an adjuvant to general anaesthesia, in children undergoing elective ear, nose and throat surgery. DESIGN: Double-blind, randomised, controlled study. SETTING: Hospital based, single-centre study in Chile. PATIENTS: ASA I-II children, aged 2 to 12 years, scheduled for elective tonsillectomy. INTERVENTION: We standardised the induction and maintenance of anaesthesia. Patients were randomly allocated to lidocaine (1.5 mg kg intravenous lidocaine over 5 min followed by 2 mg kg h) or 0.9% saline (at the same rate and volume). Infusions were continued until the end of the surgery. MAIN OUTCOME MEASURES: Presence of at least one episode of vomiting, retching or both in the first 24 h postoperatively (POV). SECONDARY OUTCOMES: Plasma concentrations of lidocaine and postoperative pain. RESULTS: Ninety-two children were enrolled. Primary outcome data were available for 91. In the Lidocaine group, 28 of 46 patients (60.8%) experienced POV, compared with 37 of 45 patients (82.2%) in the Saline group [difference in proportions 21.3% (95% confidence interval (CI) 2.8 to 38.8), P = 0.024]. The intention-to-treat analysis showed that when we assumed that the patient in the Saline group lost to follow-up did not have POV, the difference in proportions decreased to 19.6% (95% CI, 0.9 to 37.2), with an unadjusted odds ratio of 0.38 (95% CI, 0.15 to 0.97, P = 0.044). The odds of having POV were 62% less likely in those patients receiving lidocaine compared with patients in the Saline group. The mean lidocaine plasma concentration was 3.91 MUg ml (range: 0.87 to 4.88). CONCLUSION: Using an intravenous lidocaine infusion as an adjuvant to general anaesthesia decreased POV in children undergoing elective tonsillectomy.

AB - AIMS: Patient-held records are becoming more commonly used in health care, particularly in chronic diseases like glaucoma. There is a lack of evidence to support their use, however. This study examines the change in knowledge scores within a group following the introduction of a newly designed glaucoma logbook. METHODS: This analysis uses a test and retest method where patients undergoing treatment for glaucoma or ocular hypertension were assessed using a validated knowledge questionnaire. They were then given a personalized glaucoma logbook and their knowledge scores retested after 4 to 8 weeks. The change in knowledge score was examined using a Wilcoxon signed-rank test. RESULTS: A total of 56 patients were recruited and 35 completed both questionnaires equating to a 62.5% retention rate. The analysis showed a significant increase in the knowledge score attained following introduction of the questionnaire (Z=-4.176, P<0.001). CONCLUSIONS: In this format, the glaucoma logbook has a positive impact on patient knowledge. Further research will be necessary to show if this result is maintained in a larger sample group and to investigate whether this improvement in knowledge is associated with any improvement in long-term structural and functional outcomes. PMID- 29570110 TI - Pain and mortality: mechanisms for a relationship. AB - Moderate to severe chronic pain affects 1 in 5 adults and its impact increases with age. People with chronic pain that interferes with their lives have an increased risk of mortality. Identifying how interfering chronic pain can lead to mortality may highlight potential intervention strategies. This study uses a novel approach to test whether lifestyle, health, social, and psychological factors mediate the relationship between pain and mortality. Survival analyses (Cox's proportional hazard modelling and a technique to assess mediation within survival models) were conducted on a large population study of adults aged 50 years or older from the English Longitudinal Study of Ageing (n = 6324). Data collected at wave 2 (2004) were used as baseline and follow-up was until 2012. The relationship between being "often troubled with pain" and mortality was examined. Lifestyle, health, social, and psychological factors were tested as potential mediators. The strongest mediating factors for the relationship between troubling pain and mortality were functional limitation (hazard ratio 1.31; 95% confidence interval 1.20-1.39), symptoms preventing walking quarter of a mile (1.45 [1.35-1.58]), physical inactivity (1.14 [1.10-1.20]), and poor self-rated health (1.32 [1.23-1.41]). Mediators of the relationship between troubling pain and mortality provide targets for preventive health programmes. Interventions to improve general health, activity, and function could improve long-term survival in patients with this clinical problem. PMID- 29570111 TI - Association between aortic knob width and invasively measured aortic pulse pressure. AB - BACKGROUND: Aortic knob width (AKW), which can be measured easily in simple radiography, is associated with the degree of dilatation and tortuosity of the aortic arch. Pulsatile stress influences aortic geometry. This study was carried out to investigate whether AKW can represent invasively measured aortic pulse pressure (APP). METHODS: A total of 252 patients who underwent invasive coronary angiography (ICA) for the evaluation of coronary artery disease were enrolled. AKW was defined as the perpendicular length from the lateral margin of the main bronchus to the most prominent edge of the aortic knob on chest radiography. APP was measured at the ascending aorta using a pigtail catheter immediately before ICA. RESULTS: When patients were divided into two groups according to the median value of APP (69 mmHg), AKW was significantly greater in patients with higher APP (>=69 mmHg) than in those with lower APP (<69 mmHg) (40.6+/-4.9 vs. 38.1+/-4.2 mm, P<0.001). There was a positive linear correlation between APP and AKW (r=0.207, P<0.001). In multiple linear regression analysis, the significant association between APP and AKW remained even after controlling for the confounding factors, including age, sex, height, heart rate, smoking status, left ventricular ejection fraction, and left ventricular end-diastolic dimension (beta=0.131, P=0.031). CONCLUSION: Greater AKW on chest radiography was independently predictive of increased APP in patients undergoing elective ICA. The results of this study suggest that AKW can be useful as a simple surrogate marker of APP. PMID- 29570112 TI - Frontiers in Opioid Pharmacology. PMID- 29570113 TI - Potential learning and memory disruptors and enhancers in a simple, 1-day operant task in mice. AB - The objective of this study was to develop a rapid, 1-day learning and memory assay in mice that is sensitive to the effects of compounds that could impair or enhance acquisition and retrieval. Swiss-Webster, male mice were placed in experimental chambers for a 1-h acquisition session with an intermittent, audible tone. If a nose-poke response occurred during the tone, an Ensure water solution was presented. After 1 h, the mice returned to the chambers for 2 h. Drugs were injected before or after sessions to determine the effects on acquisition and/or retrieval. Mice injected with saline learned a nose-poke response as measured by decreased latencies to earn 10 reinforcers, increased reinforced response rates, and decreased nonreinforced response rates. Scopolamine and acetazolamide impaired retrieval of the nose-poke response, whereas ketamine only modestly impaired retrieval. Doses of 8-OH-DPAT or the novel carbonic anhydrase activator, MAI27, either had no effect or impaired some measures of responding. Neither 8-OH DPAT nor MAI27 were able to prevent the modest impairments produced by ketamine. The simple, 1-day operant task is a rapid assay that can be used as an initial screen to test the effects of learning and memory disruptors and potentially enhancers. PMID- 29570114 TI - Fatty acid-binding proteins 5 and 7 gene deletion increases sucrose consumption and diminishes forced swim immobility time. AB - Inhibition and genetic deletion of fatty acid-binding proteins (FABPs) 5 and 7 have been shown to increase the levels of the endocannabinoid anandamide as well as the related N-acylethanolamine's palmitoylethanolamide and oleoylethanolamide. This study examined the role of these FABPs on forced-swim (FS) behavior and on sucrose consumption in two experiments: (experiment 1) using wild-type (WT) mice treated with the FABP inhibitor SBFI26 or vehicle and (experiment 2) using WT and FABP5/7 deficient mice. Results from experiment 1 showed that acute treatment with SBFI26 did not have any effect on sucrose intake or FS behavior in mice. In experiment 2, male and female FABP5/7 deficient mice showed significant increases in sucrose consumption (25 and 21%, respectively) compared with their WT counterparts. In addition, immobility time during the FS was decreased by 27% in both male and female FABP5/7 knockout mice compared with their WT counterparts. The fact that such differences were seen between the acute pharmacological approach and the genetic approach (gene deletion) of FABP needs to be further investigated. The function of FABPs and their specific effects on endocannabinoid anandamide, oleoylethanolamide, and palmitoylethanolamide may play an important role in the development of reward and mood behaviors and could provide opportunities for potential therapeutic targets. PMID- 29570115 TI - Crestal Sinus Augmentation in the Presence of Severe Sinus Mucosal Thickening: A Report of 3 Cases. AB - PURPOSE: In the presence of severe sinus mucosal thickening, the ostium can be blocked when the sinus membrane is lifted, causing drainage disturbances and sinusitis. Here, we present 3 cases in which maxillary sinus floor elevation was performed using a crestal approach in the presence of severe sinus mucosal thickening (>10 mm). MATERIALS AND METHODS: The effects of maxillary sinus floor elevation using the crestal approach technique on sinus mucosal thickening and bone formation in the sinus were evaluated using cone beam computed tomography. RESULTS: None of the patients exhibited an increase in sinus membrane thickness. No complications were encountered during the follow-up periods, and bone formation was observed around the implants at the sinus floor. All implants were functioning successfully. CONCLUSIONS: Maxillary sinus floor elevation using the crestal approach technique in the presence of severe sinus mucosal thickening allows for minimally invasive sinus grafting and simultaneous implant placement and does not increase sinus membrane thickness.

AB - OBJECTIVE: To evaluate the speech-in-noise performance of listeners with different levels of hearing loss in a variety of complex listening environments. DESIGN: The quick speech-in-noise (QuickSIN)-based test battery was used to measure the speech recognition performance of listeners with different levels of hearing loss. Subjective estimates of speech reception thresholds (SRTs) corresponding to 100% and 0% speech intelligibility, respectively, were obtained using a method of adjustment before objective measurement of the actual SRT corresponding to 50% speech intelligibility in every listening condition. RESULTS: Of the seven alternative listening conditions, two conditions, one involving time-compressed, reverberant speech (TC+Rev), and the other (N0Spi) having in-phase noise masker (N0) and out-of-phase target (Spi), were found to be substantially more sensitive to the effect of hearing loss than the standard QuickSIN test. The performance in these two conditions also correlated with self reported difficulties in attention/concentration during speech communication and in localizing the sound source, respectively. Hearing thresholds could account for about 50% or less variance in SRTs in any listening condition. Subjectively estimated SRTs (SRTs corresponding to 0% and 100% speech intelligibility) were highly correlated with the objective SRT measurements (SRT corresponding to 50% speech intelligibility). CONCLUSIONS: A test battery that includes the TC+Rev and the N0Spi conditions would be useful in identifying individuals with hearing loss with speech-in-noise deficits in everyday communication. PMID- 29570118 TI - Comparison of the Lubricity and Surface Roughness of 5 Cosmetic Contact Lenses. AB - OBJECTIVES: Cosmetic contact lenses are increasingly popular because of their eye enhancing cosmetic benefits. The pigment particles used in these lenses can impact lens surface characteristics. This article examines the surface characteristics and the differences between the clear and the pigmented regions among five limbal ring design lenses. METHODS: Scanning electron microscopy was used to determine the location and depth of the pigment particles from the lens surface. The coefficient of friction (CoF) was determined with a Basalt-MUST microtribometer at clear and pigmented regions on either the front or the back surface. Atomic force microscopy was used to determine the surface roughness of each lens in root-mean-square (RMS) units at clear and pigmented regions. A linear mixed model for repeated measures was used for the analysis of the CoF and RMS roughness to compare all lenses. RESULTS: Four lens types had pigments exposed on the surface and one lens type had pigment fully enclosed. The CoF difference between clear and pigmented regions were similar and not statistically significant (P=0.0124) for the lens type with pigments enclosed, whereas the CoF difference for the other four lens types showed statistically significant difference (P<0.0001). CONCLUSIONS: Of the lenses tested here, cosmetic contact lenses with pigments enclosed in the lens matrix provided a more consistent surface between clear and pigmented regions compared with lenses that had exposed pigments. PMID- 29570119 TI - H3K4 Methylation Regulates LPS-Induced Proinflammatory Cytokine Expression and Release in Macrophages. AB - Histone methylation is an important epigenetic mechanism that plays an essential role in regulating gene expression in mammalian cells. To understand its influence on inflammation, methylation of H3K4, H3K9, H3K36, H3K79, and H4K20, the most common histones methylated in the inflammatory response, was analyzed in murine RAW264.7 cells and bone marrow-derived macrophages (BMDMs) upon LPS stimulation. LPS stimulation resulted in enhanced methylation at H3K4 and H3K9 in both RAW264.7 and BMDMs. To further confirm whether LPS-stimulated H3K4me2 and H3K9me2 were responsible for subsequent proinflammatory cytokine expression, the recruitment of H3K4me2 and H3K9me2 at the promoters of IL-6 and TNF-alpha was assessed. H3K4me2, but not H3K9me2, was enriched at the promoters of both IL-6 and TNF-alpha. Furthermore, LPS-stimulated gene expression and release of IL-6 and TNF-alpha were markedly suppressed in macrophages by MTA, a specific inhibitor of H3K4 methylation. These results demonstrate that histone methylation, in particular H3K4me2, plays a critical role in the regulation of LPS-induced expression and release of IL-6 and TNF-alpha. PMID- 29570120 TI - Mortality Associated With Emergency Department Boarding Exposure: Are There Differences Between Patients Admitted to ICU and Non-ICU Settings? AB - BACKGROUND: Emergency Department (ED) boarding threatens patient safety. It is unclear whether boarding differentially affects patients admitted to intensive care units (ICUs) versus non-ICU settings. RESEARCH DESIGN AND SUBJECTS: We performed a 2-hospital, 18-month, cross-sectional, observational, descriptive study of adult patients admitted from the ED. We used Kaplan-Meier estimation and Cox Proportional Hazards regression to describe differences in boarding time among patients who died during hospitalization versus those who survived, controlling for covariates that could affect mortality risk or boarding exposure, and separately evaluating patients admitted to ICUs versus non-ICU settings. MEASURES: We extracted age, race, sex, time variables, admission unit, hospital disposition, and Elixhauser comorbidity measures and calculated boarding time for each admitted patient. RESULTS: Among 39,781 admissions from the EDs (21.3% to ICUs), non-ICU patients who died in-hospital had a 1.2-fold risk (95% confidence interval, 1.03-1.36; P=0.016) of having experienced longer boarding times than survivors, accounting for covariates. We did not observe a difference among patients admitted to ICUs. CONCLUSIONS: Among non-ICU patients, those who died during hospitalization were more likely to have had incrementally longer boarding exposure than those who survived. This difference was not observed for ICU patients. Boarding risk mitigation strategies focused on ICU patients may have accounted for this difference, but we caution against interpreting that boarding can be safe. Segmentation by patients admitted to ICU versus non-ICU settings in boarding research may be valuable in ensuring that the safety of both groups is considered in hospital flow and boarding care improvements. PMID- 29570121 TI - Progression of Adjacent-level Degeneration After Lumbar Total Disc Replacement: Results of a Post-hoc Analysis of Patients With Available Radiographs From a Prospective Study With 5-year Follow-up. AB - STUDY DESIGN: Post-hoc analysis of 5-year follow-up data from a randomized, multicenter trial. OBJECTIVE: The aim of this study was to investigate the incidence of progression in radiographic adjacent-level degeneration (DeltaALD) from preoperative assessment to 5 years after total disc replacement (TDR) and the relationship of these changes with range of motion and clinical adjacent level disease. A secondary objective was to compare adjacent-level degeneration (ALD) outcomes between TDR and fusion. SUMMARY OF BACKGROUND DATA: Fusion is associated with high rates of ALD in symptomatic lumbar disc degeneration. TDR may reduce this risk. METHODS: In total, 175 patients with single-level, symptomatic, lumbar disc degeneration who had received activL or ProDisc-L and had a preoperative and 5-year postoperative radiograph available were included. Over 5-year follow-up, DeltaALD was defined as an increase in ALD of >=1 grade and clinical ALD was defined as surgical treatment at the level adjacent to an index TDR. Matching-adjusted indirect comparisons were conducted to compare ALD outcomes after TDR (current trial) with those after fusion (published trial). RESULTS: At 5-year follow-up, 9.7% (17/175) of TDR patients had DeltaALD at the superior level. In patients with preoperative ALD at the superior level, most (88% [23/26]) showed no radiographic progression over 5 years. The rate of clinical ALD was 2.3% (4/175) and none of these patients had ALD at baseline. For each degree of range of motion gained at the TDR level, there was a consistent decrease in the percentage of patients with DeltaALD. After matching and adjustment of baseline characteristics, TDR had a significantly lower likelihood of DeltaALD than fusion (odds ratio 0.32; 95% confidence interval 0.13, 0.76). CONCLUSION: The rates of DeltaALD and clinical ALD in this TDR population were similar to those previously reported in the literature for TDR at 5-year follow up. TDR had a significantly lower rate of DeltaALD than fusion. LEVEL OF EVIDENCE: 3. PMID- 29570123 TI - Artefacts in occupational stress research.

PMID- 29570125 TI - Improvement to visualization of nodes in breast cancer patients following audit: are we seeing the problem? AB - Successful localization of nodes in breast cancer patients depends upon the effectiveness of the lymphoscintigraphy technique employed. A benefit of performing imaging as part of this procedure is that it allows sites to audit their technique. An audit of breast cancer patients at the Glasgow Royal Infirmary (GRI) hospital showed nodes to be visualized in only 81% of patients. Current guidelines state that nodes should be seen in more than 95% of patients. A period of investigation and review led to changes being made to the injection and imaging technique employed at the GRI site. Following these changes a re audit was performed that showed that the node visualization rate has successfully been increased to 97%, thereby meeting the standards set in the guidelines. This technical note details the results of the initial audit and re-audit, and explains the investigation and changes made to clinical procedures at the GRI site to improve the node visualization rate. The challenges that can occur when performing breast sentinel node procedures are also discussed. PMID- 29570126 TI - The Association of Abdominal Striae With Pelvic Organ Prolapse. AB - OBJECTIVE: Our objective was to estimate the prevalence of abdominal wall striae among women with and without pelvic organ prolapse (POP) in a population with pelvic floor disorders. METHODS: This cross-sectional study included nonpregnant women with urinary incontinence and POP presenting to a tertiary urogynecology practice between December 2012 and August 2013. Participants completed a nonvalidated questionnaire about striae, and the degree of abdominal wall striae was quantified on physical examination. Baseline demographics, clinical characteristics, and Pelvic Organ Prolapse Quantification (POP-Q) measurements were recorded. RESULTS: One hundred thirty-two women were approached for participation, of which 110 (83%) completed study questionnaires. Of these 110, 59 had POP defined at POP-Q stages 2-4, whereas 51 had normal pelvic support, POP Q stages 0-1. The mean (SD) age was 55.5 (12) years, and most (78/110) were sexually active. Women with POP were more parous than women without POP (median 2 vs 1, respectively; P = 0.03). However, there was no difference in medical comorbidities, smoking status, or steroid use between groups (P > 0.05). More women with POP reported striae (42/59 [71%] vs 23/51 [45%], P = 0.006) and had quantifiable abdominal wall striae compared with women with normal support (39/59 [66%] vs 22/51 [44%], P = 0.02). On multivariate logistic regression, women with POP were 2.5 times more likely to have striae compared with women without POP after adjusting for skin type and smoking status (odds ratio, 2.5; 95% confidence interval, 1.03-6.06; P = 0.04). CONCLUSION: Women with POP are more likely to have striae compared with women without POP. PMID- 29570127 TI - Successful Treatment of Paradoxical Puborectalis Contraction and Intractable Anorectal Pain With Sacral Neuromodulation. AB - BACKGROUND: Paradoxical puborectalis contraction (PPC) is a syndrome of obstructed defecation associated with a cluster of complaints including rectal pain, incomplete evacuatory sensation, prolonged repetitive straining with bowel movements, and the need for digital manipulation. Traditional treatment has yielded mixed results. CASE: We present a case of PPC successfully treated with staged sacral neuromodulation and review her diagnostic features, medical regimen, and prior unsuccessful interventions tried. Symptoms were analyzed using a visual analog scale pain score (0-10). Criteria to progress to implantation of the pulse generator included a pain score less than 3 during test stimulation and/or greater than 50% decrease in the pain score compared to baseline.Our patient had a pain score of 0 (baseline 8) with stage 1 sacral neuromodulation. In addition, she had dramatic relief in her straining with bowel movements and need for digital manipulation. Her pulse generator was implanted after a 2-week trial, and she has experienced a lasting improvement at her follow-up of 2 years. CONCLUSIONS: Sacral neuromodulation is an established therapy for overactive bladder syndrome, urinary retention, and fecal incontinence. In urology, the use of sacral neuromodulation has been described to benefit some patients with pelvic floor pain. Sacral neuromodulation can be a successful treatment for PPC and functional anorectal pain with resulting improvement in quality of life without the sequelae of an invasive and irreversible surgery. PMID- 29570128 TI - Small Subset of Adenoid Cystic Carcinoma of the Skin Is Associated With Alterations of the MYBL1 Gene Similar to Their Extracutaneous Counterparts. AB - Adenoid cystic carcinoma (ACC) of the skin is a rare malignant neoplasm histologically identical to homonymous tumors in other organs. Cutaneous ACC has been found to harbor MYB gene activations, either through MYB chromosomal abnormalities or by generation of the MYB-NFIB fusion. In salivary gland ACC, in addition to the MYB gene, alterations in MYBL1, the gene closely related to MYB, have been reported. We studied 10 cases of cutaneous ACC (6 women, 4 men; and age range 51-83 years) for alterations in the MYB, NFIB, and MYBL1 genes, using FISH and PCR. MYB break-apart and NFIB break-apart tests were positive in 4 and 5 cases, respectively. MYB-NFIB fusions were found in 4 cases. The break of MYBL1 was found in 2 cases, and in one of them, the NFIB break-apart probe was positive, strongly indicating a MYBL1-NFIB fusion. In 2 cases, the MYB break apart test was positive, whereas no MYB-NFIB was detected, strongly suggesting another fusion partner. It is concluded that MYBL1 alterations are detected in primary cutaneous ACC but are apparently less common compared with MYB and NFIB alterations. PMID- 29570129 TI - CD34 and BerEP4 Are Helpful to Distinguish Basaloid Tricholemmoma From Basal Cell Carcinoma. AB - Tricholemmoma, a benign follicular neoplasm with outer root sheath differentiation, typically comprises clear or pale cells, and when multiple is pathognomic of Cowden's syndrome. The tumor is probably underrecognized and in basaloid examples can be difficult to distinguish from basal cell carcinoma (BCC). We studied 55 tricholemmomas (including 15 basaloid cases) and compared immunohistochemical profile with nodular BCC from our archives. Basaloid and non basaloid tricholemmomas had similar staining characteristics. BerEP4 was focally positive (range 10%-20%) in only 3/39 (7.7%) tricholemmomas compared with widespread positivity in BCC (90.8%, 139 of 151 cases with >=50% tumor area stained). CD34 was expressed, usually focally (median 20%, range 10%-90%), in 52/53 (98.1%) tricholemmomas and was negative in all 21 BCCs stained. EMA staining lacked sensitivity or specificity in differentiating tricholemmoma from BCC. Five or more Merkel cells were found in 7/17 (40.1%) tricholemmomas and 1/23 (4.3%) nodular BCCs studied. In summary, immunohistochemistry is helpful in distinction between tricholemmoma, including difficult basaloid examples (BerEP4 negative or focal, CD34 positive) compared with BCC (BerEP4 widespread in most cases, CD34 negative). The presence of 5 or more Merkel cells is a relatively specific but not a particularly sensitive discriminator. PMID- 29570130 TI - Cholesterol Clefts in Basal Cell Carcinoma: An Under-Recognized Association. AB - Cholesterol clefts have rarely been described in cutaneous tumors other than lipid-rich tumors. However, they seem to be a relatively common phenomenon in basal cell carcinoma (BCC). This study was undertaken to determine the frequency of cholesterol cleft deposition in BCCs, and to identify associated histopathologic and clinical features. Twenty-eight of 249 BCC cases reviewed showed features of cholesterol cleft. Mean disease duration in those with cholesterol cleft was significantly longer than in those without cholesterol cleft (5.58 vs. 3.29 years, respectively; P = 0.013). Sex and age distributions, and average tumor longest diameter (11.6 vs. 9.41 mm) were no different for those with or without cholesterol clefts. The most common anatomical location was the nose in both those with and without cholesterol clefts. BCCs without cholesterol clefts more frequently involved the periauricular and perioral areas, and areas other than the head and neck, such as the trunk and lower extremities (P = 0.087). Histopathologic features of necrosis (26/28, 92.86%), keratinization (19/28, 67.86%), and pigment deposition (18/28, 64.29%) were found to be associated with cholesterol clefts. Cholesterol clefts were intratumorally located in 27/28 cases (96.43%), and stromally located in 2 cases (7.14%); intravascularly located cholesterol clefts were observed in no case. In conclusion, this study shows that cholesterol clefts are relatively common in BCC, and suggests that cholesterol crystal deposition could be associated with longer disease duration and microtrauma.

PMID- 29570132 TI - Xanthomatous Cells in Cutaneous Graft-Versus-Host Disease Biopsies: A Clue for the Diagnosis of Hepatic Graft-Versus-Host Disease. AB - Graft-versus-host disease (GVHD) is one of the most common and serious complications of hematopoietic stem-cell transplantation that mainly affects the skin, gastrointestinal tract, and liver. Hepatic GVHD is associated with high morbidity and mortality, and its diagnosis can be especially challenging because of nonspecific clinical signs and symptoms. It must be suspected in patients with elevated liver enzymes and cholestasis, especially in those with a history of preceding skin rash and diarrhea. We describe 3 patients with cutaneous and hepatic GVHD that presented with severe hypercholesterolemia and hypertriglyceridemia, and no xanthomatous macular lesions, in which cutaneous biopsies revealed the presence of xanthomatous dermal histiocytes. We propose that the presence of these xanthomatous cells in skin biopsies from patients with cutaneous GVHD could be a dermatopathological clue for the diagnosis of hepatic GVHD. PMID- 29570133 TI - Small Vessel Vasculitis in Herpes Zoster-Discussion of Current Aspects of Varicella Zoster Virus Vasculopathy. AB - Varicella zoster virus (VZV) vasculopathy was initially described as herpes zoster ophthalmicus with contralateral hemiplegia in 1896. VZV is able to infect endothelial cells directly, leading to a thickened intima and vascular remodeling due to inflammation. Therefore, a spectrum of vasculopathies is induced, ranging from a discrete capillaritis-to-granulomatous vasculitis and obliterative angiitis. Cutaneous vasculitic changes sui generis with leukocytoclasia, cell debris, vascular damage, and endothelial swelling are very rare feature of herpetic infections in skin biopsies. We report an immunocompetent patient who presented with a rare form of cutaneous VZV infection of the upper leg characterized by vasculitic changes of the small vessels without typical herpetic epidermal features or neural involvement. Intriguingly, the vasculitis appeared prior to the characteristic vesicular rush without any pain symptoms. Because VZV can cause vasculopathic damage mainly within the central nervous system in immunocompetent and immunosuppressed patients, we recommend continuous clinical controls to recognize central symptoms that are related to VZV vasculopathy or giant cell arteriitis.

AB - OBJECTIVES: The aims of the study were to evaluate human papillomavirus (HPV) and cervical cancer knowledge in a population at high risk for cervical cancer and to determine whether knowledge and attitudes toward HPV vaccination improve after educational intervention. MATERIALS AND METHODS: This pre-post survey design study was conducted at the John H. Stroger Hospital of Cook County colposcopy clinic. An HPV knowledge and awareness survey was given to participants before their clinical encounter. Afterward, participants watched an educational video and repeated the survey, which was administered again at the follow-up visit. Knowledge scores and acceptability of HPV vaccination were compared across all surveys. RESULTS: Among the 104 participants who completed baseline and immediate postintervention surveys, the average baseline score was 9.6 of 20. Knowledge scores improved after the educational intervention (mean = 14.1, p < .0001) and remained elevated in the 44 participants that completed long-term follow-up (mean = 13.5, p < .0001). Acceptability of HPV vaccination for participants themselves increased from 47.1% to 76% (p < .0001) and for children/grandchildren increased from 30.8% to 71.2% (p < .0001) after the intervention. Overall, women were worried about HPV and cervical cancer for themselves and their children/grandchildren at baseline. However, the intervention improved perceptions about HPV vaccination cost, safety, adverse effects, and efficacy. CONCLUSIONS: Knowledge of HPV, cervical cancer, and HPV vaccination is low in this high-risk population and may improve with a simple educational intervention. Increased knowledge was associated with an increase in vaccine acceptability and improved perceptions about HPV vaccination. Educational interventions targeted toward high-risk women are necessary to decrease cervical cancer incidence and mortality. PMID- 29570137 TI - Statistical Modeling for Quality Assurance of Human Papillomavirus DNA Batch Testing. AB - OBJECTIVES: Our objective was to simulate the distribution of human papillomavirus (HPV) DNA test results from a 96-well microplate assay to identify results that may be consistent with well-to-well contamination, enabling programs to apply specific quality assurance parameters. MATERIALS AND METHODS: For this modeling study, we designed an algorithm that generated the analysis population of 900,000 to simulate the results of 10,000 microplate assays, assuming discrete HPV prevalences of 12%, 13%, 14%, 15%, and 16%. Using binomial draws, the algorithm created a vector of results for each prevalence and reassembled them into 96-well matrices for results distribution analysis of the number of positive cells and number and size of cell clusters (>=2 positive cells horizontally or vertically adjacent) per matrix. RESULTS: For simulation conditions of 12% and 16% HPV prevalence, 95% of the matrices displayed the following characteristics: 5 to 17 and 8 to 22 total positive cells, 0 to 4 and 0 to 5 positive cell clusters, and largest cluster sizes of up to 5 and up to 6 positive cells, respectively. CONCLUSIONS: Our results suggest that screening programs in regions with an oncogenic HPV prevalence of 12% to 16% can expect 5 to 22 positive results per microplate in approximately 95% of assays and 0 to 5 positive results clusters with no cluster larger than 6 positive results. Results consistently outside of these ranges deviate from what is statistically expected and could be the result of well-to-well contamination. Our results provide guidance that laboratories can use to identify microplates suspicious for well-to-well contamination, enabling improved quality assurance. PMID- 29570138 TI - Vulvovaginal Disease Education in Canadian and American Gynecology Residency Programs: A Survey of Program Directors. AB - OBJECTIVE: The aims of the study were to assess and describe the current vulvovaginal curriculum in gynecology residency training programs in Canada and the United States and to compare this with national training objectives. MATERIALS AND METHODS: A 22-question electronic survey was sent to 252 gynecology program directors in Canada and the United States between September 2015 and July 2016 using the platform SurveyMonkey.com. Survey responses were entered into SPSS Version 23, and analysis was performed using descriptive statistics. RESULTS: Overall, 58 (23%) of 252 programs directors responded. Nearly all of the sites provided formal teaching on pain disorders (54/58, 93%), vulvar dermatoses (54/58, 93%), and vulvovaginal infections (57/58, 98%). Exposure to vulvovaginal clinics varied widely. On average, program directors estimated that residents spend a median of 10 hours (0-200) in vulvar pain clinics, 9 hours (0-200) in dermatology clinics, and 50 hours (0-480) in colposcopy clinics during residency training. Most program directors (53/57, 93%) believed that all general gynecologists should be able to manage vulvar disorders in practice. Reported obstacles to treating vulvar disorders included lack of training (41/58, 71%) and lack of interest (35/58, 60%). CONCLUSIONS: While most residency programs provided formal education on vulvovaginal diseases, clinical exposure is extremely variable between sites. When it is not possible to increase clinical exposure to vulvovaginal disorders, traditional training methods (lectures, textbooks) should be supplemented with online modules and other means of learning to improve resident knowledge of vulvovaginal diseases. PMID- 29570139 TI - Prevalence of Suspected Nonalcoholic Fatty Liver Disease in Lean Adolescents in the United States. AB - OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) can develop in lean subjects referred to as lean NAFLD. We aim to evaluate the prevalence and risk factors of NAFLD in lean adolescents in the United States (US). METHODS: Cross sectional data from 1482 lean subjects (body mass index <85th percentile) ages between 12 and 18 years, who were enrolled in the National Health and Examination Survey during the 2005 to 2014 cycles were included. We defined suspected NAFLD as alanine aminotransferase >25.8 U/L for boys and >22.1 U/L for girls; hypertriglyceridemia as triglycerides >=150 mg/dL; low HDL as HDL <40 mg/dL and insulin resistance (IR) as homeostatic model assessment of IR >=3. RESULTS: The mean weighted prevalence of suspected NAFLD among lean adolescents during 2005 to 2014 cycles was 8% (95% CI 6.2-9.9). Lean subjects with suspected NAFLD were significantly older compared with lean non-NAFLD subjects (15.5 vs 15 years, P value <0.05). Low HDL (15.5% vs 6.8%; P value 0.016) and hypertriglyceridemia (10% vs 3.9%; P value 0.028) were also found to be more common among lean NAFLD subjects compared with their non-NAFLD counterparts. Presence of IR increased the risk of having suspected NAFLD by 4-fold among lean adolescents. Non-Hispanic black lean adolescents were less likely to have suspected NAFLD compared with non Hispanic white lean adolescents. CONCLUSIONS: The estimated prevalence of suspected NAFLD among lean adolescents in the US was found to be 8% with evidence of metabolic derangements such as low HDL, hypertriglyceridemia, and IR.

PMID- 29570144 TI - The Imperative of Solving Nurses' Usability Problems With Health Information Technology. AB - BACKGROUND: Health information technology (IT) usability issues are a key concern for nurse executives and nurses. OBJECTIVES: The aims of this study are to understand usability pain points faced by nurses regarding the use of health IT, identify their impact and importance, discuss responsibilities, and develop possible solutions to improve the health IT-user experience for nurses. METHODS: Twenty-seven experts were interviewed including nursing leaders, informaticists, executives, engineers, researchers, and human factors experts across acute care, long-term care, and vendor settings. Semistructured questions guided the interviews, and content analysis was used to identify themes. RESULTS: Four themes emerged: 1) user experience pain points, 2) importance of the issues, 3) the responsibility gap, and 4) acting on usability issues. CONCLUSION: Nurses continue to endure significant health IT-usability issues that negatively impact patients, nurses, and healthcare organizations. Solutions include enhancing the voice of nursing at the national and local levels, creating a digital strategy for nursing, providing incentives to improve usability in health IT, and accelerating the understanding of nurses' work intended to inform and translate nurses' work into health IT design. PMID- 29570145 TI - The Effects of Social Influence on Nurses' Hand Hygiene Behaviors. AB - OBJECTIVE: The aim of this article is to describe the associations of nurses' hand hygiene (HH) attitudes, subjective norms, and perceived behavioral control with observed and self-reported HH behavior. BACKGROUND: Hand hygiene is an essential strategy to prevent healthcare-associated infections. Despite tremendous efforts, nurses' HH adherence rates remain suboptimal. METHODS: This quantitative descriptive study of ICU nurses in the southeastern United States was guided by the theory of planned behavior. The self-administered Patient Safety Opinion Survey and iScrub application, which facilitates observation, comprised the data set. RESULTS: Nurses' observed HH median was 55%; tendency to self-report was a much higher 90%. Subjective norm and perceived control scores were associated with observed and self-reported HH (P < .05) but not attitude scores or reports of intention. CONCLUSIONS: Nurses' subjective norm and perceived control are associated with observed and self-reported HH performance. Healthcare workers overestimate their HH performance. Findings suggest future research to explore manipulators of these variables to change nurses' HH behavior.

AB - BACKGROUND AND AIMS: A growing body of evidence supports the need for detailed attention to nutrition and diet in children with inflammatory bowel disease (IBD). We aimed to define the steps in instituting dietary or nutritional management in light of the current evidence and to offer a useful and practical guide to physicians and dieticians involved in the care of pediatric IBD patients. METHODS: A group of 20 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to Nutrition Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition Porto, IBD Interest, and Nutrition Committee. A list of 41 predefined questions was addressed by working subgroups based on a systematic review of the literature. RESULTS: A total of 53 formal recommendations and 47 practice points were endorsed with a consensus rate of at least 80% on the following topics: nutritional assessment; macronutrients needs; trace elements, minerals, and vitamins; nutrition as a primary therapy of pediatric IBD; probiotics and prebiotics; specific dietary restrictions; and dietary compounds and the risk of IBD. CONCLUSIONS: This position paper represents a useful guide to help the clinicians in the management of nutrition issues in children with IBD. PMID- 29570148 TI - Errata. PMID- 29570149 TI - Errata. PMID- 29570150 TI - Cost-Effectiveness Research in Anesthesiology. AB - Perioperative interventions aimed at decreasing costs and improving outcomes have become increasingly popular in recent years. Anesthesiologists are often faced with a choice among different treatment strategies with little data available on the comparative cost-effectiveness. We performed a systematic review of the English language literature between 1980 and 2014 to identify cost-effectiveness analyses of anesthesiology and perioperative medicine interventions. We excluded interventions related to critical care or pediatric anesthesiology, and articles on interventions not normally ordered or performed by anesthesiologists. Of the >5000 cost-effectiveness analyses published to date, only 28 were applicable to anesthesiology and perioperative medicine and met inclusion criteria. Multidisciplinary interventions were the most cost-effective overall; 8 of 8 interventions were "dominant" (improved outcomes, reduced cost) or cost effective, including accelerated, standardized perioperative recovery pathways, and perioperative delirium prevention bundles. Intraoperative measures were dominant in 3 of 5 cases, including spinal anesthesia for benign abdominal hysterectomy. With regard to prevention of perioperative infection, methicillin resistant Staphylococcus aureus (MRSA) decolonization was dominant or cost effective in 2 of 2 studies. Three studies assessing various antibiotic prophylaxis regimens had mixed results. Autologous blood donation was not found to be cost-effective in 5 of 7 studies, and intraoperative cell salvage therapy was also not cost-effective in 2 of 2 reports. Overall, there remains a paucity of cost-effectiveness literature in anesthesiology, particularly relating to intraoperative interventions and multidisciplinary perioperative interventions. Based on the available studies, multidisciplinary perioperative optimization interventions such as accelerated, standardized perioperative recovery pathways, and perioperative delirium prevention bundles tended to be most cost-effective. Our review demonstrates that there is a need for more rigorous cost-effective analyses in many areas of anesthesiology and that anesthesiologists should continue to lead collaborative, multidisciplinary efforts in perioperative medicine. PMID- 29570151 TI - Incidence and Risk Factors for Chronic Postoperative Opioid Use After Major Spine Surgery: A Cross-Sectional Study With Longitudinal Outcome. AB - BACKGROUND: Chronic opioid use is a significant public health concern. Surgery is a risk factor for developing chronic opioid use. Patients undergoing major spine surgery frequently are prescribed opioids preoperatively and may be at risk for chronic opioid use postoperatively. The aim of this study was to investigate the incidence of and perioperative risk factors associated with chronic opioid use after major spine surgery. METHODS: The records of patients who underwent elective major spine surgery at the University of Virginia between March 2011 and February 2016 were retrospectively reviewed. The primary outcome was chronic opioid use through 12 months postoperatively. Demographic data, medical comorbidities, preoperative pain scores, and medication use including daily morphine-equivalent (ME) dose, intraoperative use of lidocaine and ketamine, estimated blood loss, postoperative pain scores and medication use, and postoperative opioid use were collected. Logistic regression models were used to examine factors associated with chronic opioid use. RESULTS: Of 1477 patient records reviewed, 412 patients (27.9%) were opioid naive and 1065 patients (72.3%) used opioids before surgery. Opioid data were available for 1325 patients, while 152 patients were lost to 12-month follow-up and were excluded. Of 958 preoperative opioid users, 498 (52.0%) remained chronic users through 12 months. There was a decrease in opioid dosage (mg ME) from preoperative to 12 months postoperatively with a mean difference of -14.7 mg ME (standard deviation, 1.57; 95% confidence interval [CI], -17.8 to -11.7). Among 367 previously opioid naive patients, 67 (18.3%) became chronic opioid users. Factors associated with chronic opioid use were examined using logistic regression models. Preoperative opioid users were nearly 4 times more likely to be chronic opioid users through 12 months than were opioid-naive patients (odds ratio, 3.95; 95% CI, 2.51-6.33; P < .001). Mean postoperative pain score (0-10) was associated with increased odds of chronic opioid use (odds ratio for a 1 unit increase in pain score 1.25, 95% CI, 1.13-1.38; P < .001). Use of intravenous ketamine or lidocaine was not associated with chronic opioid use through 12 months. CONCLUSIONS: Greater than 70% of patients presenting for major spine surgery used opioids preoperatively. Preoperative opioid use and higher postoperative pain scores were associated with chronic opioid use through 12 months. Use of ketamine and lidocaine did not decrease the risk for chronic opioid use. Surveillance of patients for these factors may identify those at highest risk for chronic opioid use and target them for intervention and reduction strategies. PMID- 29570152 TI - Opioid Use Disorders and the Risk of Postoperative Pulmonary Complications. AB - BACKGROUND: As the rate of opioid use disorders continues to rise, perioperative physicians are increasingly faced with the challenge of providing analgesia to these patients after surgery. Due to the likelihood of opioid dose escalation in the perioperative period, we hypothesized that opioid-dependent patients would be at increased risk for postoperative pulmonary complications. METHODS: A retrospective cross-sectional analysis of patients undergoing 6 representative elective surgical procedures was performed using the Nationwide Inpatient Sample from 2002 to 2011. The primary outcome was a composite including prolonged mechanical ventilation, reintubation, and acute respiratory failure. Secondary outcomes were length of stay, in-hospital mortality, and total hospital costs. Both multivariable logistic regression and propensity score matching were used to determine the impact of opioid use disorder on outcomes. RESULTS: The total sample-weighted cohort consisted of 7,533,050 patients. Patients with opioid use disorders were more likely to suffer pulmonary complications, with a frequency of 4.2% compared to 1.6% in the nonopioid-dependent group (P < .001), and had a 1.62 times higher odds (95% confidence interval [CI], 1.16-2.27) in multivariable regression analysis. In a secondary subgroup analysis, only patients undergoing a colectomy had a greater odds of suffering pulmonary complications (odds ratio, 2.64; 95% CI, 1.42-4.91; P = .0021). Additionally, patients with an opioid use disorder had a longer length of stay (0.84 days [95% CI, 0.52-1.16; P < .001]) and greater costs ($1816 [95% CI, 935-2698; P < .001]). CONCLUSIONS: This study demonstrates that patients with opioid use disorders are at increased risk for postoperative pulmonary complications, and have prolonged length of stay and resource utilization. Further research is needed regarding interventions to reduce the risk of complications in this subset of patients. PMID- 29570153 TI - Neural Invasion Spreads Macrophage-Related Allodynia via Neural Root in Pancreatic Cancer. AB - BACKGROUND: Neural invasion (N-inv) induces the neural damage and pain in pancreatic cancer (PCa). Benign nerve injury evokes allodynia through neuroinflammation in the neural root, which might be seen in PCa. Macrophages have the potential to release excitatory cytokines after nerve injury and so may play a role in the generation of chronic neuropathic pain. The aim of this study is to represent N-inv-induced allodynia in patients with PCa and to characterize allodynia-related neuroinflammation as macrophage accumulation on dorsal root ganglion (DRG) in the N-inv animal model (N-inv model). METHODS: Treatment-naive patients with advanced PCa with no opioid use were enrolled in the clinical study. To evaluate allodynia, the current perception threshold on epigastric skin and pain score from questionnaire were measured. The association between the degrees of radiological N-inv and allodynia was evaluated. In the animal experiments, we used the N-inv model, which is established by the inoculation of the human PCa cell line into the left sciatic nerve of mice and mimics the invasion behavior of human PCa. The change of sensation was weekly measured at right hind paw, and the expressions of mRNA and protein were investigated on DRG at 6 weeks in the N-inv and sham models. The effect of macrophage depletion using liposome-encapsulated clodronate (Lp-CLD) was evaluated in the N-inv model. Tumor size and the degree of macrophage accumulation on DRG or around the tumor were investigated. RESULTS: In the clinical study, 43 patients were analyzed. The threshold of epigastric skin at 2000 Hz touch and pressure sensation was decreased in patients with severe N-inv, compared to patients without severe N inv. Patients with severe N-inv showed a high pain score. In the animal experiments, the N-inv model decreased the threshold of right hind paw at 5 and 6 weeks. The macrophage-related gene expression and F4/80-positive macrophages were increased in the left DRG. Lp-CLD-induced macrophage depletion induced an increase of the threshold in the right hind paw and a decrease of CD206-positive macrophages accumulation in the left DRG. Lp-CLD had no effect for tumor size. CONCLUSIONS: The present study first showed that the N-inv-induced allodynia was spread in patients with PCa and in the N-inv model. Allodynia was related to the amount of macrophages at DRG in the N-inv model. The neuroinflammation may be a target for researching the N-inv-induced pain mechanism and developing novel analgesics.

Male and female immune systems vary considerably, and the immune system plays an important role in limiting cancer growth. Currently, mouse models describing the impact of volatile anesthetics on cancer growth are limited to same-sex models. In this brief report, we describe a sex-specific impact of isoflurane on melanoma growth observed in wild-type but not in immune-deficient mice.

AB - This research focuses on femoral head wedge resection for the treatment of avascular necrosis (AVN) of the femoral head. A 9-year-old girl presented to the emergency room complaining of right hip pain that occurred after a pedestrian car accident. After 8 months of internal fixation using cannulated screws for Delbet type 2 fracture of the femoral neck, AVN of the femoral head developed in the patient. Even though valgus-derotation-extension intertrochanteric osteotomy was performed for the treatment of AVN, it progressed further and femoral head wedge resection was performed to recover the femoral head sphericity. After 3 years of follow-up, radiograph results showed appropriate and satisfactory congruency and containment. This research shows that the treatment of AVN of the femoral head using femoral head wedge resection is an effective method that can yield excellent results. PMID- 29570158 TI - Growth hormone promotes neurite growth of spiral ganglion neurons. AB - Intact spiral ganglion neurons are a specific requirement for hearing rehabilitation in deaf patients by cochlear implantation. Neurotrophic growth factors have been proposed as effective tools to protect and regenerate spiral ganglion neurons that are degenerated in the majority of patients suffering from hearing loss. Here, we show that growth hormone (GH), a pleiotropic growth factor whose neurotrophic role in the inner ear is still unclear, significantly increases neurite extension, as well as neuronal branching, in spiral ganglion cell cultures derived from early postnatal rats. Our data suggest that GH can act as a potent neurotrophic factor for inner ear neurons, which specifically promotes neurite growth. These effects might be elicited in a direct way or, alternatively, by induction of other growth factors that account for the observed neurotrophic effects. Thus, we conlude that GH might represent a novel candidate for the treatment of neurodegeneration in the hearing-impaired inner ear that has the potential to ultimately improve the performance and outcome of modern auditory implants. PMID- 29570159 TI - Generation of human vascularized brain organoids. AB - The aim of this study was to vascularize brain organoids with a patient's own endothelial cells (ECs). Induced pluripotent stem cells (iPSCs) of one UC Davis patient were grown into whole-brain organoids. Simultaneously, iPSCs from the same patient were differentiated into ECs. On day 34, the organoid was re embedded in Matrigel with 250 000 ECs. Vascularized organoids were grown in vitro for 3-5 weeks or transplanted into immunodeficient mice on day 54, and animals were perfused on day 68. Coating of brain organoids on day 34 with ECs led to robust vascularization of the organoid after 3-5 weeks in vitro and 2 weeks in vivo. Human CD31-positive blood vessels were found inside and in-between rosettes within the center of the organoid after transplantation. Vascularization of brain organoids with a patient's own iPSC-derived ECs is technically feasible. PMID- 29570161 TI - Authors' Response.

Descriptive profile of lumbopelvic control in collegiate baseball pitchers. J Strength Cond Res 32(4): 1150-1154, 2018-Throwing a baseball requires the transmission of forces generated in the lower extremity, through the trunk, then to the upper extremity, and ultimately out through the ball. Disruptions in this kinetic chain, specifically in lumbopelvic control, have been associated with decreased pitching performance and increased risk of injury. The purpose of this study was to establish normative data of lumbopelvic control among collegiate baseball pitchers. Data were compared bilaterally and with a group of nonthrowing physically active individuals. Eighteen asymptomatic pitchers and 30 nonthrowing subjects participated in this study. Each subject performed 6 separate tests bilaterally: single-leg balance, single-leg mini-squat, and static single-leg bridge. An iPod based tilt sensor was placed around the waist of each subject and used to determine the amount of anterior-posterior lumbopelvic tilt during each test. Independent t tests showed that neither group had any bilateral differences in lumbopelvic control (p > 0.10). The groups had similar lumbopelvic tilt values during the single-leg balance (p > 0.08) and mini-squat tests (p > 0.72), but a significant difference during the bridge maneuver. For this test, the pitchers had less lumbopelvic control than the control group for both the lead leg (p = 0.003) and trail leg (p = 0.01). The descriptive values of this study may assist in designing lumbopelvic conditioning programs with the intent of enhancing pitching performance, as well as in the prevention, evaluation, and treatment of various injuries associated with lumbopelvic control deviations. PMID- 29570162 TI - IL-34 Inhibits Acute Rejection of Rat Liver Transplantation by Inducing Kupffer Cell M2 Polarization. AB - BACKGROUND: Recent studies have demonstrated that IL-34 is implicated in the regulation of macrophage functions. However, the effect of IL-34 on Kupffer cells (KCs) in acute rejection (AR) of liver transplantation remains unclear. METHODS: IL-34 expression was detected in graft and serum from allotransplantation and syngeneic transplantation groups. The adeno-associated virus-expressing IL-34 was used to assess the effect of IL-34 on AR of rat liver transplantation. The effect of IL-34 on KC polarization was evaluated by in vitro and in vivo assays. Kupffer cells in donors were depleted by clodronate treatment before transplantation, and the nontreated KCs or lipopolysaccharide-treated KCs were transferred into recipients during liver transplantation. RESULTS: IL-34 expression levels in grafts and serum were decreased in the allotransplantation group compared with the syngeneic transplantation group. Adeno-associated virus-expressing IL-34 treatment induced KC M2 polarization in vivo and inhibited the AR of rat liver transplantation. Moreover, we found that IL-34 switched the phenotype of KCs from M1 to M2 by activating the PI3K/Akt pathway in vitro. In addition, the results of KC deletion and adaptive transfer experiments showed that the AR inhibition induced by IL-34 was M2 KC-dependent. CONCLUSIONS: IL-34 plays an important role in KC M2 polarization-dependent AR inhibition of rat liver transplantation.

AB - BACKGROUND: The use of belatacept is not yet approved for maintenance in kidney transplant patients. This retrospective multicenter European study aimed to assess the efficacy and safety of conversion to belatacept in a large cohort of patients in a real-life setting and to identify the predictive factors for improved kidney function after the switch. METHODS: Two hundred nineteen maintenance kidney transplant patients from 5 European kidney transplant centers were converted to belatacept at 21.2 months (0.1-337.1 months) posttransplantation, mainly because of impaired kidney function. Thirty-two patients were converted to belatacept within the first 3 months posttransplantation. The mean duration of follow-up was 21.9 +/- 20.2 months. RESULTS: The actuarial rate of patients still on belatacept-based therapy was 77.6%. Mean estimated glomerular filtration rate increased from 32 +/- 16.4 at baseline to 38 +/- 20 mL/min per 1.73 m (P < 0.0001) at last follow-up. Conversion to belatacept before 3 months posttransplantation was the main predictive factor for a significant increase in estimated glomerular filtration rate (of 5 and 10 mL/min per 1.73 m at 3 and 12 months after the switch, respectively). Eighteen patients (8.2%) presented with an acute rejection episode after conversion; 3 developed a donor-specific antibody. Overall efficacy and safety were good, including for the 35 patients that had a donor-specific antibody at conversion. CONCLUSIONS: The conversion to belatacept was effective, especially when performed early after transplantation. PMID- 29570164 TI - The Benefits of Hypothermic Machine Preservation and Short Cold Ischemia Times in Deceased Donor Kidneys. AB - BACKGROUND: Hypothermic machine perfusion (HMP) of deceased donor kidneys is associated with better outcome when compared to static cold storage (CS). Nevertheless, there is little evidence whether kidneys with short cold ischemia time (CIT) also benefit from HMP and whether HMP can safely extend CIT. METHODS: We analyzed prospectively collected data from the Machine Preservation Trial, an international randomized controlled trial. Seven hundred fifty-two consecutive renal transplants were included: 1 kidney of each of the 376 donors was preserved by HMP, the contralateral organ was preserved by CS. RESULTS: The mean CIT was 3:05 PM (SD, 4:58 AM). A subgroup analysis was performed, groups were based on CIT duration: 0 to 10 hours, 10 to 15 hours, 15 to 20 hours, or 20 hours or longer. Delayed graft function (DGF) incidence in the subgroup with up to 10 hours CIT was 6.0% (N = 3/50) in the HMP arm and 28.1% (N = 18/64) in the CS arm (univariable P = 0.002; multivariable odds ratio [OR], 0.02; P = 0.007). Cold ischemia time remained an independent risk factor for DGF for machine perfused kidneys recovered from donation after brain death donors (OR, 1.06; 95% confidence interval [CI], 1.017-1.117; P = 0.008), donation after circulatory death donors (OR, 1.13; 95% CI, 1.035-1.233; P = 0.006) and expanded criteria donors (OR, 1.14; 95% CI, 1.057-1.236; P = 0.001). CONCLUSIONS: In conclusion, HMP resulted in remarkably lower rates of DGF in renal grafts that were transplanted after a short CIT. Also, CIT remained an independent risk factor for DGF in HMP-preserved kidneys. PMID- 29570165 TI - Minimizing Risk Associated With Older Liver Donors by Matching to Preferred Recipients: A National Registry and Validation Study. AB - BACKGROUND: Allografts from older liver donors (OLDs), 70 years or older are often discarded for fear of inferior outcomes. We previously identified "preferred recipients" who did not suffer the higher risk of graft loss and mortality associated with OLDs. Preferred recipients were first-time, non-status 1 registrants older than 45 years, body mass index less than 35, indication other than hepatitis C, and cold ischemia time less than 8 hours. METHODS: We assessed the validity of the preferred recipient construct in a larger, more recent cohort (38 891 patients, 2006-2013). We compared recipients of OLD grafts to recipients of average liver donors (ALDs, age = 40-69) and ideal liver donors (ILDs, age = 18-39) grafts using multilevel Cox regression adjusting for recipient and transplant factors. RESULTS: The use of OLD grafts in preferred recipients has increased from 2006 to 2013 (P = 0.02). Preferred recipients Model for End-Stage Liver Disease scores ranged 6 to 40. Preferred recipients had similar 5-year all cause graft loss (ACGL) with OLD versus ALD and ILD grafts (25.4% vs 24.5% and 21.6%). Conversely, nonpreferred recipients had higher 5-year ACGL with OLD versus ALD and ILD grafts (41.4% vs 32.9% and 25.6%). After adjustment, preferred recipients had similar graft loss with OLD versus ALD grafts (hazard ratio [HR], 0.921.081.27; P = 0.3) and ILD grafts (HR, 0.981.161.39, P = 0.09); however, nonpreferred recipients had higher ACGL risk with OLD grafts versus ALD (HR, 1.281.411.56, P < 0.001) and ILD grafts (HR, 1.501.671.86, P < 0.001). Similar trends are seen with mortality. CONCLUSIONS: Because preferred recipients comprise 43.3% (n = 2916) of the current waitlist and span the full range of Model for End-Stage Liver Disease scores, transplanted OLD allografts could be distributed without added risk of graft loss or mortality.

PMID- 29570167 TI - Advanced Morphologic Analysis for Diagnosing Allograft Rejection: The Case of Cardiac Transplant Rejection. AB - Allograft rejection remains a significant concern after all solid organ transplants. Although qualitative morphologic analysis with histologic grading of biopsy samples is the main tool employed for diagnosing allograft rejection, this standard has significant limitations in precision and accuracy that affect patient care. The use of endomyocardial biopsy to diagnose cardiac allograft rejection illustrates the significant shortcomings of current approaches for diagnosing allograft rejection. Despite disappointing interobserver variability, concerns about discordance with clinical trajectories, attempts at revising the histologic criteria and efforts to establish new diagnostic tools with imaging and gene expression profiling, no method has yet supplanted endomyocardial biopsy as the diagnostic gold standard. In this context, automated approaches to complex data analysis problems-often referred to as "machine learning"-represent promising strategies to improve overall diagnostic accuracy. By focusing on cardiac allograft rejection, where tissue sampling is relatively frequent, this review highlights the limitations of the current approach to diagnosing allograft rejection, introduces the basic methodology behind machine learning and automated image feature detection, and highlights the initial successes of these approaches within cardiovascular medicine. PMID- 29570169 TI - Telomerase reverse transcriptase promoter mutations and solar elastosis in cutaneous melanoma. AB - The aims of this study were to assess the prognostic potential of solar elastosis grading and telomerase reverse transcriptase (TERT) promoter mutations (TERTp) in melanoma and to evaluate whether an association between solar elastosis and TERTp exists. Solar elastosis in the dermis was evaluated in hematoxylin and eosin stained whole slides from 486 malignant melanomas. Pyrosequencing was used to detect TERTp in 189 samples. There was no association between solar elastosis and TERTp (P=0.3). Severe elastosis was associated with older age (P<0.0001), ulceration (P=0.03), and location in the head/neck region (P<0.0001). The absence of elastosis was associated with younger age (P<0.0001), benign nevus remnants (P=0.001), and a positive BRAF V600E expression (P<0.0001). Severe elastosis predicted a worse relapse-free survival (hazard ratio: 2.18; 95% confidence interval: 1.30-3.64; P=0.003). However, it was not independent of age. TERTp was not associated with any adverse prognostic or clinicopathological outcome, nor any mitogen-activated protein kinase-related protein expressions. However, at a cutoff corresponding to the sensitivity of Sanger sequencing, TERTp predicted melanoma-specific death independently of age, and was associated with Breslow thickness, ulceration, tumor stage at diagnosis, BRAF V600E oncoprotein, and absence of p16 expression. In conclusion, TERTp were not related to severe elastosis and may thus be triggered by both chronic and acute intermittent sun exposure, the latter not visible on ordinary hematoxylin and eosin-stained slides. Neither TERTp nor severe elastosis predicted an adverse outcome in melanoma. An absence of elastosis was seen in younger melanoma patients and may be used to select those melanomas originating in a nevus, which often harbors a BRAF mutation. PMID- 29570170 TI - Fatty acid receptor GPR120: a novel marker for human melanoma. AB - The correlation between ultraviolet radiation of the skin and melanoma incidence in humans is well established. Interestingly, epidemiologic data suggest also a correlation to an increased BMI pointing to metabolic trigger factors in melanoma pathogenesis. To substantiate this connection, we studied the expression of G protein-coupled receptor 120 (GPR120), a receptor sensitive to unsaturated long chain free fatty acids in melanoma tissues. One-hundred fourteen tissue sections histologically confirmed as nevi (n=32), primary melanoma (n=39), and melanoma metastasis (n=43) were immunohistochemically stained against GPR120. The staining was evaluated by three trained dermatopathologists and independently scored. Compared with nevi, primary melanoma and melanoma metastasis showed significantly higher levels of GPR120 staining. Only three out of 32 nevi showed strong GPR120 expression [median immunoreactivity-scoring system (IRS) score: 1, range: 0-10], whereas in primary melanomas 14 out of 39 were highly GPR120-positive (median IRS score: 7, range: 0-12) and in melanoma metastasis 27 out of 43 were highly GPR120 positive (median IRS score: 9, range: 0-12). GPR120 expression and tumor thickness (mm) show a statistically significant correlation in primary melanoma (P=0.011). Moreover, GPR120-positive staining was found throughout the epidermis and in sebaceous and sweat glands, which is yet not described. This study identified GPR120 as a novel marker for melanoma, indicating that melanoma cells are sensitive to free fatty acids. It is tempting to speculate that pharmacologically interfering with GPR120 signaling might improve melanoma therapy. PMID- 29570171 TI - Factors Associated With Health Care Utilization of Recurrent Clostridium difficile Infection in New York State. AB - BACKGROUND: The incidence of infection due to Clostridium difficile infection (CDI) and subsequent economic burden are substantial. GOALS: The impact of changing practice patterns on demographics at risk and utilization of health care resources for recurrence of CDI remains unclear. STUDY: A total of 291,163 patients hospitalized for CDI were identified from 1995 to 2014 from the New York SPARCS database. The chi test, the Welch t test, and multivariable logistic regression analysis were performed to evaluate factors related to readmission. RESULTS: Hospital admissions and readmissions for CDI peaked in 2008 at 20,487 and 13,795, respectively, and have since decreased (linear trend, 0.9706 and 0.9464, respectively; P<0.0001). In total, 60,077 (21%) patients required >=2 admissions. Risk factors for readmission included: age 55 to 74, government insurance, hypertension, diabetes, anemia, hypothyroidism, chronic pulmonary disease, rheumatoid arthritis, renal failure, peripheral vascular disease, and depression (all P<0.05). Trends in surgery showed a similar peak in 2008 at 165 and have since decreased (linear trend, 0.8660; P<0.0001). A total of 1830 (0.63%) patients with CDI underwent surgery, with emergent being more common than elective (71% vs. 29%). CONCLUSIONS: Hospital admissions and readmissions for CDI peaked in 2008 and have since been steadily declining. These trends may be secondary to improved diagnostic capabilities and evolving antibiotic regimens. More than 1 in 5 hospitalized patients had at least 1 readmission. Numerous risk factors for these patients have been identified. Although <1% of all patients with CDI undergo surgery, these rates have also been declining. PMID- 29570173 TI - Gastric Emptying of Elemental Liquid Diets Versus Semisolid Diets in Bedridden Gastrostomy-fed Patients. AB - BACKGROUND: Aspiration is a common problem in bedridden gastrostomy-fed patients. We compared gastric emptying of an elemental liquid diet and a commercial semisolid diet in bedridden gastrostomy-fed patients. METHODS: Study 1: from January 2013 to December 2016, consecutive bedridden patients receiving percutaneous endoscopic gastrostomy (PEG) semisolid feeding hospitalized due to aspiration pneumonia were switched to elemental liquid diet feedings. The frequency of defecation, tube feed contents aspirated from the trachea, and aspiration pneumonia during hospitalization were retrospectively reviewed. Study 2 was a randomized, crossover trial comparing C sodium acetate gastric emptying of a commercial elemental liquid or a commercial semisolid diet in bedridden PEG patients and controls. RESULTS: Study 1: 18 patients were enrolled. Elemental liquid diet was aspirated from the trachea in 1 (5.6%) (once in 24 observations); neither aspiration pneumonia nor diarrhea developed during elemental liquid diet feeding over 2 weeks observation. Study 2: 8 PEG patients and 8 healthy subjects were separately randomized to assess gastric emptying of the commercial elemental and semisolid diets. The elemental liquid diet was associated with a significant decrease of the 10%, 30%, or 50% emptying (excretion) time (P<0.05) and an increased the area under the curve (% dose/h) compared with the commercial semisolid diet (P<0.05). In healthy subjects there was no significant difference in gastric empting between the 2 diets. CONCLUSIONS: Elemental liquid diets emptied more rapidly from the stomach than semisolid diets in bedridden PEG patients. They may prevent or reduce aspiration pneumonia compared with semisolid diets.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 29570172 TI - Sessile Serrated Adenomas in Young Patients may have Limited Risk of Malignant Progression. AB - GOALS: To provide preliminary evidence that sessile serrated adenomas (SSA) are low-risk polyps in young patients. BACKGROUND: SSAs are the dominant polyp of the serrated neoplasia pathway and as such are the precursor of up to 20% of colorectal carcinomas (CRC). Up to 90% of these cancers are expected to harbor a BRAF mutation. SSAs are being diagnosed with increasing frequency in young patients, placing a significant burden on colonoscopic services. Evidence to direct the surveillance intervals for these young patients is not available. STUDY: We utilized 2 patient cohorts comprising (1) a consecutive series of patients who underwent outpatient colonoscopy through a tertiary hospital and (2) a consecutive series of resection specimens for CRC processed through a gastrointestinal pathology service. The prevalence of SSAs by age was determined in the patients undergoing colonoscopy and compared with the ages of patients with BRAF mutated CRC in the pathology series. RESULTS: The prevalence of SSAs was similar irrespective of age. By comparison, BRAF mutated CRCs were very rare (3.8% of cases) in patients younger than 50 years of age and uncommon (9.3% of cases) in patients younger than 60 years of age, but increased to 39.8% in patients older than 80 years of age. CONCLUSIONS: These results suggest that SSAs develop at a young age, but have a prolonged dwell time and are unlikely to develop into cancer in patients younger than 60 years of age. These findings highlight the need for further targeted research to determine the most appropriate surveillance intervals for young patients with sporadic SSAs.

PMID- 29570175 TI - Optimizing Accessibility of a Hand-Wash Gel to Infant's Cradle: Effect on Neonatal Conjunctivitis. AB - BACKGROUND: In our recent study in 2015, we showed a significant relationship between increased rate of clinical neonatal conjunctivitis (CNC) and performance of eye red reflex (RR) examination. Our study aim was to assess whether improved accessibility of staff to disinfectant gel (via attaching the gel bottle to infant's cradle) will increase the caring staff compliance with hand hygiene and decrease the rate of CNC. METHODS: Our intervention included attaching bottles of alcohol-based gel to newborns' cradles to insure full availability and accessibility of hand-wash disinfectant. We included all newborn infants who were born beyond 35 weeks' gestation and stayed in the well-baby nursery. We compared two periods: pre-intervention period (n=9380) vs. an intervention period (n=8087). Three variables were recorded: (a) rate of CNC: number of conjunctival swabs sampled /1000 newborns whenever an eye discharge was noted, (b) rate of bacterial conjunctivitis: number of positive swabs/1000 newborns, (c) percentage of positive swabs out of all sampled swabs. RESULTS: Compared to pre-intervention period, the rate of CNC dropped significantly during the intervention period: 28.6/1,000 vs. 21.3/1,000, respectively, p<0.01. However, the number of positive bacterial swabs/1000 newborns (3.2 vs. 2.5) and the percentage of positive bacterial swabs of all sent samples (11.6% vs. 10.8%) were not different between the two periods. The majority of pathogens in swabs were gram-negative sp. without difference between study periods (77.4% versus 80%), respectively. Univariate analysis showed significant association between rate of CNC and longer length of stay> 5days (p<0.001) and vaginal delivery (VD). Logistic stepwise regression analysis showed that 4 variables were significantly and independently associated with higher rate of clinical conjunctivitis. These include birth during pre-intervention period (p=0.018, OR 1.27, 95% CI 1.04-1.54), length of stay 4-5 days (p<0.001, OR 2.23 CI 1.63-3.06), length of stay > 7 days (p<0.001, OR 6.51 CI 4.24-10.02), vaginal delivery (p=0.004, OR 1.6 CI 1.17-2.2) and male gender (p=0.006, OR 1.31 CI 1.08-1.59). CONCLUSIONS: Accessibility of a disinfectant gel within each newborn's cradle raised hygiene awareness among the caring staff and contributed to reduction of CNC rate in the newborn nursery.

PMID- 29570178 TI - Predictors of Intravenous Immunoglobulin Nonresponse and Racial Disparities in Kawasaki Disease. AB - BACKGROUND: Kawasaki disease (KD) is the most common cause of acquired heart disease in American children. Intravenous immunoglobulin (IVIG) nonresponse is a known risk factor for cardiac sequelae. Previously reported risk factors for nonresponse include age, male sex and laboratory abnormalities. We set out to identify additional risk factors for IVIG nonresponse in a racially diverse KD population. METHODS: We conducted a retrospective chart review at a referral center in the Southeastern United States of children meeting ICD-9 (International Statistical Classification of Disease and Related Health Problems) criteria for KD and being treated with IVIG. RESULTS: Four-hundred and fifty-nine children met inclusion criteria, 67 were excluded for subsequent rheumatologic diagnosis, unknown race, or failure to meet the American Heart Association guideline criteria. Our final cohort consisted of 392 subjects, with median age of 2.7 years, 65.1% male, 66.1% White, 24.2% Black, 4.9% Asian and 82.9% responded to a single dose of IVIG. Coronary ectasia or aneurysm developed in 27%; 7.4% developed aneurysms and 2.3% giant coronary aneurysms. Nonresponders were more likely to be Black, have higher white blood cell, erythrocyte sedimentation rate and C-reactive protein, lower hemoglobin, develop ectasia or aneurysm and require critical care and hospital readmission. Responders achieved echocardiographic normalization more often compared with nonresponders (81.3% vs. 60.9%, P = 0.002) and coronary artery pseudonormalization (87.2% vs. 69.7%, P = 0.03) at 1 year. Black nonresponders had the slowest normalization at 1 year (52.9%, P = 0.02). CONCLUSIONS: Nonresponders have higher rates and greater severity of coronary involvement than responders. Our study uniquely demonstrates Black race as a risk factor for nonresponse and for delayed normalization of cardiac involvement at 1 year follow-up.

PMID- 29570181 TI - [Benign liver tumours - current diagnostics and therapeutic modalities]. AB - The most common benign liver tumours are haemangiomas, focal nodular hyperplasia and hepatocellular adenoma. We perform a review of the literature and show the current diagnostic and therapeutic modalities based on the EASL Clinical Practice Guideline. With the widespread use of ultrasound, the detection of liver lesions is increased. They are usually found in women of childbearing age with atypical abdominal pain or incidentally. Contrast-enhanced US, CT or MRI are usually necessary for differential diagnosis. In atypical appearance or in malignancy suspect cases biopsy could be performed. For symptomatic patients conservative therapy can be sufficient. In haemorrhagic cases transarterial embolisation can be useful, also for tumour size decreasing before surgery. In patients with persisting symptoms, with vessel or soft tissue compression effect or in malignancy suspect cases definitive surgical treatment is advised. In men with hepatocellular adenoma primary resection is appropriate because of the higher risk for malignant transformation. As alternative treatment options radiofrequency ablation, irradiation, chemotherapy, monoclonal antibody therapy or liver transplantation are published. PMID- 29570182 TI - [Surgical treatment of primary liver malignancies]. AB - The incidence of primary malignant liver tumours is globally rising. Hepatocellular carcinoma constitutes 75-85% of primary liver malignancies. Owing to advancements of oncological therapies, several methods are available to combat the tumour. Upon the complexity of the disease and the wide spectrum of therapeutical regimens, therapy of HCC is debated, with several undecided issues. Noteworthy, however, is that in early tumour stages, as a de facto curative approach, surgical therapy remains the most effective, allowing long-term survival. Intrahepatic cholangiocellular carcinoma (iCCC) is the second most frequent primary malignant liver tumour. Despite technical developments, prognosis of iCCC patients remains dismal. Unfortunately, as the sole curative approach, surgery (nearing 40% 5-year survival) is mostly contraindicated because of a late diagnosis. In these cases, median survival remains below 7-12 months despite parallel palliative therapies. The present review focuses on the surgical management of primary malignant liver tumours. PMID- 29570183 TI - [Liver transplantation in the treatment of hepatic tumors]. AB - The indications for liver transplantation have become generally accepted over the last decades. However, in the last ten years, this indication area changes, it seems to be enlarged. Increasingly, previously classified as contraindications have become indications like cholangiocarcinoma or colorectal cancer liver metastases in selected cases. We have reviewed the old and new oncologic indications, whose survival rates do not differ from liver transplants due to other indications. PMID- 29570184 TI - [Surgical treatment of secondary liver malignancies]. AB - Surgical treatment of liver metastases, under certain conditions, can be a step of a multidisciplinary treatment strategy for advanced malignant disease. Nevertheless, it is not the same if metachronous or synchronous metastases are planned to be treated. Indications for surgery are the most clearly defined and accepted in cases of colorectal and neuroendocrine liver metastases. At the same time, the steps of the traditional oncotherapy has changed in the management of synchronous colorectal metastases: the novel concept of the treatment strategy is removing the liver metastases before the colorectal primary. The role of surgery is less clear and defined in the management of metastases from other, non colorectal and non-neuroendocrine primaries. The main purpose is to evaluate which kind of criteria should be fulfilled to indicate the resection of liver metastases, which are the conditions that, when present, may provide a benefit to a patient from surgery, improving survival. These criteria have not been clarified precisely yet; randomized prospective trials are needed. Consensus recommendations in such cases could be determined based on the results of the mentioned trials. PMID- 29570185 TI - [Laparoscopy in liver surgery]. AB - More than 9000 laparoscopic liver resections (LLR) are performed worldwide for benign lesions, malignancy (mainly for hepatocellular carcinoma and colorectal cancer liver metastasis), and living donor hepatectomy. Although there is no absolute size criterion, smaller, peripheral lesions (<5 cm) of the anteriolateral segments, that lie far from major vessels and anticipated transection planes are most amenable to LLR, but nowadays lesions of the less ideal posterosuperior segments are feasible for LLR too. Centers with extensive experience in hepatobiliary surgery and laparoscopy have performed laparoscopic major hepatic resections with satisfactory outcomes. Patient benefits from LLR include less intraoperative blood loss, less postoperative pain and painkiller requirement, early mobilization and shorter length of hospital stay, with comparable postoperative morbidity and mortality to open liver resection. Comparison studies between open resection and LLR have revealed no differences in width of resection margins or overall survival after resection for hepatocellular cancer or colorectal cancer liver metastases. Other advantages of LLR for HCC are avoidance of collateral vessel ligation, decreased postoperative hepatic insufficiency and fewer postoperative adhesions, all of them facilitates a possible subsequent liver transplantation. PMID- 29570186 TI - [Role of interventional radiological procedures in the treatment of liver cancer]. AB - Invasive radiological procedures provide more and more therapeutic options for patients with liver cancer. The treatment options previously used as a 2nd/3rd line treatment are making their way to 1st line treatment in selected cases. In this review, the authors take an overview of the interventional radiological procedures used in the most frequent liver neoplasms. There is a rapid development in ablational therapy, especially in the volumetric planning and stereotactic navigation. Using those new devices, the reliability of the ablation can improve a lot. At the field of embolization, new randomized studies were published recently, which can help to choose the right patient group who gains the most from the treatment. Interventional radiology has now an established place in the team of specialists treating malignant liver diseases. PMID- 29570187 TI - [Systemic treatment options of primary hepatocellular carcinoma]. AB - Hepatocellular carcinoma is the most common primary malignancy of the liver, with increasing incidence worldwide. Chronic liver diseases, especially liver cirrhosis, are the primary risk factors in the pathogenesis. Curative therapy is usually possible only in early disease, however, most cases are diagnosed at advanced stage. Until recently sorafenib was the only viable option for systemic treatment, however, over the past years many new targeted and immunotherapy drugs proved to be efficient in first and second line as well. PMID- 29570188 TI - [Stereotactic body radiotherapy of liver metastasis: early experience]. AB - Recently the prevalence of oligometastatic patients is increasing. A common site of distant spread is the liver. The standard of care is curative surgical resection, however, the resecability rate is only 10-20%. Alternatively, radiofrequency ablation (RFA) or transarterial chemoembolization (TACE) may be used. Stereotactic ablative body radiotherapy (SABRT) makes it possible to deliver curative radiation dose without radiation injury to the healthy liver tissue. We delivered SABRT to three patients with inoperable hepatic metastases. The primary tumors were rectal (2) and lung (1). The dose was 3x20 Gy every other day. We observed one grade 1 side effect. All the metastases showed complete remission and no local recurrence or late side effect occurred during the one year of follow-up. One patient is tumor-free, one has stable disease, in one patient two new hepatic metastases appeared and receives chemo-biological therapy. SABRT of liver metastases is safe and highly effective. It can be expected that in the near future it will become one of the standard treatments of hepatic tumors. PMID- 29570189 TI - [Alcohol and breast cancer. A short survey]. AB - Regular consumption of alcohol increases the risk of developing (one or more of) several malignant conditions: the frequency of tumours in the aerodigestive tract, in the liver, in the colorectal region and in the breast is increased. The principal carcinogen component of alcoholic drinks is ethanol itself; the effect is unmistakably proportional to the daily/weekly dosage. Under the influence of alcohol-dehydrogenase, ethanol will metabolise to acetaldehyde, which is a known carcinogen. Among other things chronic alcohol consumption promotes the production of endogen hormones, affects the insulin-like growth factor-1, alters several biological pathways, raises oxidative stress, and damages the genes. Even modest daily alcohol intake will increase the risk of breast cancer. PMID- 29570190 TI - Albumin as a "Trojan Horse" for polymeric nanoconjugate transendothelial transport across tumor vasculatures for improved cancer targeting. AB - Although polymeric nanoconjugates (NCs) hold great promise for the treatment of cancer patients, their clinical utility has been hindered by the lack of efficient delivery of therapeutics to targeted tumor sites. Here, we describe an albumin-functionalized polymeric NC (Alb-NC) capable of crossing the endothelium barrier through a caveolae-mediated transcytosis pathway to better target cancer. The Alb-NC is prepared by nanoprecipitation of doxorubicin (Doxo) conjugates of poly(phenyl O-carboxyanhydrides) bearing aromatic albumin-binding domains followed by subsequent surface decoration of albumin. The administration of Alb NCs into mice bearing MCF-7 human breast cancer xenografts with limited tumor vascular permeability resulted in markedly increased tumor accumulation and anti tumor efficacy compared to their conventional counterpart PEGylated NCs (PEG NCs). The Alb-NC provides a simple, low-cost and broadly applicable strategy to improve the cancer targeting efficiency and therapeutic effectiveness of polymeric nanomedicine.

AB - Herein, by means of density functional theory (DFT) calculations, we designed a new type of thiophene-linked porphyrin unit and incorporated it into an extended 2D conjugated microporous polymer (CMP) to serve as a CO2 reduction catalyst. This newly designed catalyst combines the advantages of molecular catalysis, heterogeneous catalysis, high structural stability and tunable electronic properties. A series of metal atoms (Fe, Mg, Mn, and Cu) were introduced into the center of the porphyrin ring to modify its capacity for reducing CO2. Our transition state (TS) search calculations revealed that the Fe-modified CMP possessed the highest catalytic activity toward CO2 reduction. The plausible reduction pathway was also determined. The band structure and frontier orbital distribution calculations further demonstrated its semimetallic property and higher stimulated transition probability, both of which are critical factors for photocatalytic performance. We hope that our design could provide meaningful guidance for other relevant CO2 catalytic reactions. PMID- 29570192 TI - Evidence of homo-FRET in quantum dot-dye heterostructured assembly. AB - With an aim to understand the intermolecular/particle interaction and the optical properties of the inorganic-organic hybrid nanostructured materials, Forster resonance energy transfer (FRET) between negatively charged CdS quantum dots (donor) and positively charged Oxazine 170 perchlorate (acceptor) has been investigated by employing steady-state and time-resolved fluorescence spectroscopy. Investigations revealed that size-dependent changes in the FRET efficiency of different QD-dye FRET pairs occurred mainly due to the electrostatic effects. Interestingly, the present study also reveals that at a higher concentration of dye molecules, aggregation occurs on the QD surface and the quenching of dye fluorescence occurs due to homo-FRET process. The homo-FRET process in this case has been established by exploiting steady-state fluorescence anisotropy measurements. The feasibility of aggregate formation and the homo-FRET interaction between the dye molecules has also been demonstrated through quantum mechanical calculations. PMID- 29570194 TI - Elucidating the amphiphilic character of graphene oxide. AB - The amphiphilic character of graphene oxide was analysed in terms of its interfacial activities, using atomistic molecular dynamics. Graphene oxides at four different degrees of oxygenation were investigated considering both the effects of oxidation and carboxyl edge-functionalization. Solvation free energies are strongly negative and of increasing magnitude with the concentration for all systems, even in the toluene phase, indicating that GO presents a favourable solvation in both pure liquids as well as interfaces. The PMF results indicate that only the R20 system is slightly active at the water/vacuum interface, with a PMF minimum of about -2.6 kJ mol-1. Both analyses, free energy and PMF, indicate that all systems with higher oxygen concentrations have lower free energy in water than in toluene, while the R20 system opposes this tendency. Comparison between the reduced GOs (20%) shows that edge-functionalised systems were more active than basal-functionalized systems, indicating that oxygen concentration plays a more relevant role than the distribution of functional groups. PMID- 29570196 TI - A quantitative and temporal map of proteostasis during heat shock in Saccharomyces cerevisiae. AB - Temperature fluctuation is a common environmental stress that elicits a molecular response in order to maintain intracellular protein levels. Here, for the first time, we report a comprehensive temporal and quantitative study of the proteome during a 240 minute heat stress, using label-free mass spectrometry. We report temporal expression changes of the hallmark heat stress proteins, including many molecular chaperones, tightly coupled to their protein clients. A notable lag of 30 to 120 minutes was evident between transcriptome and proteome levels for differentially expressed genes. This targeted molecular response buffers the global proteome; fewer than 15% of proteins display significant abundance change. Additionally, a parallel study in a Hsp70 chaperone mutant (ssb1Delta) demonstrated a significantly attenuated response, at odds with the modest phenotypic effects that are observed on growth rate. We cast the global changes in temporal protein expression into protein interaction and functional networks, to afford a unique, time-resolved and quantitative description of the heat shock response in an important model organism. PMID- 29570193 TI - Phytol stimulates the browning of white adipocytes through the activation of AMP activated protein kinase (AMPK) alpha in mice fed high-fat diet. AB - Stimulating the browning of white adipocytes contributes to the restriction of obesity and related metabolic disorders. This study aimed to investigate the browning effects of phytol on mice inguinal subcutaneous white adipose tissue (iWAT) and explore the underlying mechanisms. Our results demonstrated that phytol administration decreased body weight gain and iWAT index, and stimulated the browning of mice iWAT, with the increased expression of brown adipocyte marker genes (UCP1, PRDM16, PGC1alpha, PDH, and Cyto C). In addition, phytol treatment activated the AMPKalpha signaling pathway in mice iWAT. In good agreement with the in vivo findings, the in vitro results showed that 100 MUM phytol stimulated brown adipogenic differentiation and formation of brown-like adipocytes in the differentiated 3T3-L1 by increasing the mitochondria content and oxygen consumption, and promoting mRNA and/or protein expression of brown adipocyte markers (UCP1, PRDM16, PGC1alpha, PDH, Cyto C, Cidea and Elovl3) and beige adipocyte markers (CD137 and TMEM26). Meanwhile, phytol activated the AMPKalpha signaling pathway in the differentiated 3T3-L1. However, the inhibition of AMPKalpha with Compound C totally abolished phytol-stimulated brown adipogenic differentiation and formation of brown-like adipocytes. In conclusion, these results showed that phytol stimulated the browning of mice iWAT, which was coincident with the increased formation of brown-like adipocytes in the differentiated 3T3-L1, and appeared to be primarily mediated by the AMPKalpha signaling pathway. These data provided new insight into the role of phytol in regulating the browning of WAT and suggested the potential application of phytol as a nutritional intervention for the restriction of obesity and related metabolic disorders. PMID- 29570195 TI - DNA nanoclew templated spherical nucleic acids for siRNA delivery. AB - A superior biocompatible spherical nucleic acid (SNA) conjugate was fabricated by grafting siRNA onto the surface of a core composed of a spherical DNA nanostructure that we have termed a DNA nanoclew (DC). After uptake by cultured cancer cells, SNA nanoparticles release engrafted siRNAs by cleavage of the intracellular Dicer enzyme. Moreover, in vitro experiments reveal that such SNAs demonstrate potent gene knockdown at both mRNA and protein levels, while with negligible cytotoxicity. PMID- 29570200 TI - Microfluidic determination of lymphocyte vascular deformability: effects of intracellular complexity and early immune activation. AB - Despite the critical importance of mechanical (rheological + extrudability) deformability in the vascular flow of lymphocytes, it has been poorly investigated due to the limitations of existing technological tools. Microfluidics analysis of leukocyte deformability offers significant advantages in that it offers high throughput, large sample population and the ability to analyze a heterogeneous population. These advantages are in stark contrast to previous approaches that focused on single cell measurements. Importantly, the flow characteristics of microfluidic devices more closely model vascular deformability in that shear stress is applied forcing leukocyte passage through micropores of designed size. The modeling of vascular flow has been further enhanced by the development of a microfluidic ratchet device that introduced an oscillatory flow. As demonstrated in this study, the microfluidic ratchet device was able to separate human peripheral blood leukocyte subsets (i.e., monocytes and lymphocytes) based on differential deformability profiles. Furthermore, morphologically similar lymphocyte subsets (CD4, CD8 and NK) could also be separated. The subset separation was observed to be largely due to differences in their intracellular complexity (i.e., granule content) with granule-positive T lymphocytes and NK cells being less deformable than granule-negative lymphocytes. Moreover, upon immune activation, deformability of the de-granulated lymphocytes increased consequent to the decrease in cytoplasmic granularity/viscosity. This study for the first time demonstrates that leukocytes subsets have differential deformability profiles and that intracellular granularity/degranulation significantly impacts the lymphocytes' mechanical properties. These findings could be of clinical value as biomarkers of lymphocyte activation state and potential disease processes. PMID- 29570202 TI - Introducing Molecular Omics. PMID- 29570201 TI - Anisotropic and amphoteric characteristics of diverse carbenes. AB - Despite its key importance in carbene chemistry, the amphoteric (i.e., both nucleophilic and electrophilic) behavior of the divalent carbon atom (:C) in carbenes is not well understood. The electrostatic potential (EP) around :C is often incorrectly described by simple isotropic atomic charges (particularly, as in singlet CF2); therefore, it should be described by the multipole model, which can illustrate both negative and positive EPs, favoring the positively and negatively charged species that are often present around :C. This amphotericity is much stronger in the singlet state, which has more conspicuous anisotropic charge distribution than the triplet state; this is validated by the complexation structures of carbenes interacting with Na+, Cl-, H2O, and Ag+. From the study of diverse carbenes [including CH2, CLi2/CNa2, CBe2/CMg2, CF2/CCl2, C(BH2)2/C(AlH2)2, C(CH3)2/C(SiH3)2, C(NH2)2/C(PH2)2, cyclic systems of C(CH2)2/C(CH)2, C(BHCH)2, C(CH2CH)2/C(CHCH)2, and C(NHCH)2/C(NCH)2], we elucidate the relationships between the electron configurations, electron accepting/donating strengths of atoms attached to :C, pi conjugation, singlet triplet energy gaps, anisotropic hard wall radii, anisotropic electrostatic potentials, and amphotericities of carbenes, which are vital to carbene chemistry. The (sigma2, pi2 or sigmapi) electronic configuration associated with :C on the :CA2 plane (where A is an adjacent atom) in singlet and triplet carbenes largely governs the amphoteric behaviors along the :C tip and :C face-on directions. The :C tip and :C face-on sites of sigma2 singlet carbenes tend to show negative and positive EPs, favoring nucleophiles and electrophiles, respectively; meanwhile, those of pi2 singlet carbenes, such as very highly pi conjugated 5-membered cyclic C(NCH)2, tend to show the opposite behavior. Open shell sigmapi singlet (such as highly pi-conjugated 5-membered cyclic C(CHCH)2) and triplet carbenes show less anisotropic and amphoteric behaviors. PMID- 29570203 TI - A single-molecule porphyrin-based switch for graphene nano-gaps. AB - Stable single-molecule switches with high on-off ratios are an essential component for future molecular-scale circuitry. Unfortunately, devices using gold electrodes are neither complementary metal-oxide-semiconductor (CMOS) compatible nor stable at room temperature. To overcome these limitations, several groups have been developing electroburnt graphene electrodes for single molecule electronics. Here, in anticipation of these developments, we examine how the electrical switching properties of a series of porphyrin molecules with pendant dipoles can be tuned by systematically increasing the number of spacer units between the porphyrin core and graphene electrodes. The porphyrin is sandwiched between a graphene source and drain and gated by a third electrode. It is found that the system has two stable states with high and low conductances, which can be controlled by coupling the dipole of the functionalised porphyrin to an external electric field. The associated rotation leads to the breaking of conjugation and a decrease in electrical conductances. As the number of spacers is increased, the conductance ratio can increase from 100 with one spacer to 200 with four spacers. This switching ratio is further enhanced by decreasing the temperature, reaching approximately 2200 at 100 K. This design for a molecular switch using graphene electrodes could be extended to other aromatic systems. PMID- 29570204 TI - Spatially confined luminescence process in tip-modified heterogeneous-structured microrods for high-level anti-counterfeiting. AB - Recent years have witnessed the progress of lanthanide-doped materials from fundamental material synthesis to targeted practical applications such as optical applications in photodetection, anti-counterfeiting, volumetric display, optical communication, as well as biological imaging. The unique compositions and structures of well-designed lanthanide ion-doped materials could expand and strengthen their application performances. Herein, we report dual-mode luminescent crystalline microrods that spatially confine upconversion and downconversion photophysical process within defined regions using the specially designed heterogeneous structure. Through an epitaxial growth procedure, downconversion tips have been conjugated with the parent upconversion microrods in oriented directions. This spatially confined structure can effectively depress the deleterious energy depletion in lanthanide ions homogeneously doped materials, and as a result, the red, green, and blue upconversion intensities have been enhanced by 334, 225, and 22 times, respectively. Moreover, the induced tips hardly disturb the upconversion process of the microrod seeds. Upon 980 nm laser or ultraviolet lamp excitation, tunable emission colors were realized in the single tip-modified microrod, indicating potential applications of these microrods for high-level dual-mode anti-counterfeiting. PMID- 29570205 TI - Proteomic profile of 4-PBA treated human neuronal cells during ER stress. AB - Perturbations affecting the homoeostasis of endoplasmic reticulum (ER) activate an adaptive signaling known as the unfolded protein response or UPR. Many studies have reported the association between neurological disorders and ER stress. Decreasing ER stress may therefore aid in therapeutic control of neuronal diseases. Sodium 4-phenylbutyrate (4-PBA), a small molecule, has been shown to alleviate ER stress and various neurological diseases, but the mechanistic basis of its action is not well understood. Using an iTRAQ based LC-MS technique we have delineated the effect of 4-PBA on the proteome of human neuroblastoma cells (SK-N-SH) during Tunicamycin-induced ER stress. The proteomic profile of 4-PBA treated cells revealed that 4-PBA does not alter the cellular proteome to adapt towards ER stress. However, it can alleviate both the toxicity and proteomic alterations, induced by an ER stress inducer. Hence, the therapeutic effect of 4 PBA is primarily due to its ability to resolve ER stress rather than its ability to alter the expression of proteins required for maintaining ER proteostasis. Thus, we posit here that 4-PBA acts as an authentic chemical chaperone by aiding protein folding in the ER. PMID- 29570207 TI - Silencing of c-Ski augments TGF-beta1-induced epithelial-mesenchymal transition in cardiomyocyte H9C2 cells. AB - BACKGROUND: The shRNA lentiviral vector was constructed to silence c-Ski expression in cardiac muscle cells, with the aim of exploring the role of c-Ski in transforming growth factor beta1 (TGF-beta1)-induced epithelial-mesenchymal transitions (EMT) in H9C2 cells. METHODS: RT-PCR and western blot were used to detect c-Ski expression at protein and messenger ribonucleic acid (mRNA) levels in 5 different cell lines. Then, lentiviral vector was constructed to silence or overexpress c-Ski in H9C2 cells. MTT and/or soft agar assay and transwell assay were used to detect cell proliferation and migration, respectively. The expression levels of c-Ski under different concentrations of TGF-beta1 stimulation were detected by RT-qPCR and immunocytochemical analysis. In the presence or absence of TGF-beta1 stimulation, the proteins' expression levels of alpha-SMA, FN and E-cadherin, which are closely correlated with the process of EMT, were measured by western blot after c-Ski silencing or overexpression. Meanwhile, the effect of c-Ski on Samd3 phosphorylation with TGF-beta1 stimulation was investigated. RESULTS: There is a high expression of c-Ski at protein and mRNA levels in H9C2 cell line, which first demonstrated the presence of c-Ski expression in H9C2 cells. Overexpression of c-Ski significantly increased H9C2 cell proliferation. The ability of c-Ski gene silencing to suppress cell proliferation was gradually enhanced, and inhibition efficiency was the highest after 6 to 7 d of transfection. Moreover, H9C2 cells with c-Ski knockdown gained significantly aggressive invasive potential when compared with the control group. TGF-beta1 stimulation could dose-independently reduce c-Ski expression in H9C2 cells and lead to obvious down-regulated expression of E cadherin. Interestingly, c-Ski could restore E-cadherin expression while suppressing alpha-SMA and/or FN expression stimulated by TGF-beta1. However, shRNA-induced c-Ski knockdown aggravated only the TGF-beta1-induced EMT. Moreover, c-Ski-shRNA also promoted the phosphorylation of Samd3 induced by TGF beta1. CONCLUSION: c-Ski expression in cardiac muscle cells could be down regulated by TGF-beta1. Silencing of c-Ski gene was accompanied by down regulation of E-cadherin, up-regulation of alpha-SMA and/or FN and Smad3 phosphorylation induced by TGF-beta1, promoting EMT process. Therefore, c-Ski may be closely associated with TGF-beta1-induced EMT and play an important role in cardiac fibrosis development and progression. PMID- 29570206 TI - Participation in research improves overall patient management: insights from the Global Rheumatic Heart Disease registry (REMEDY). AB - BACKGROUND: Rheumatic heart disease (RHD) is a major public health problem in low and middle-income countries (LIMCs), with a paucity of high-quality trial data to improve patient outcomes. Investigators felt that involvement in a recent large, observational RHD study impacted positively on their practice, but this was poorly defined. AIM: The purpose of this study was to document the experience of investigators and research team members from LMICs who participated in a prospective, multi-centre study, the global Rheumatic Heart Disease Registry (REMEDY), conducted in 25 centres in 14 countries from 2010 to 2012. METHOD: We conducted an online survey of site personnel to identify and quantify their experiences. Telephone interviews were conducted with a subset of respondents to gather additional qualitative data. We asked about their experiences, positive and negative, and about any changes in RHD management practices resulting from their participation in REMEDY as a registry site. RESULTS: The majority of respondents in both the survey and telephone interviews indicated that participation as a registry site improved their management of RHD patients. Administrative changes included increased attention to follow-up appointments and details in patient records. Clinical changes included increased use of penicillin prophylaxis, and more frequent INR monitoring and contraceptive counselling. CONCLUSION: Our study demonstrates that participation in clinical research on RHD can have a positive impact on patient management. Furthermore, REMEDY has led to increased patient awareness and improved healthcare workers' knowledge and efficiency in caring for RHD patients. PMID- 29570208 TI - Sheep can be used as animal model of regional myocardial remodelling and controllable work. AB - BACKGROUND: A-V-sequential pacing has been shown to induce reversible conduction delay and subsequent asymmetric remodelling of the left ventricle (LV) in dogs and pigs. Both species have disadvantages in animal experiments. Therefore aim of this study focusses at developing a more feasible and easy-to-use animal model in sheep. METHODS: Dual-chamber pacing (DDD) pacemakers (right atrium + right ventricular free wall) were surgically implanted in 13 sheep. All animals underwent 8 weeks of chronic rapid pacing at 180 bpm. Reported observations were made at 110 bpm. RESULTS: DDD pacing acutely induced a left bundle branch block (LBBB) - like pattern with almost doubling in QRS width and septal flash, indicating mechanical dyssynchrony. Atrial pacing (AAI) resulted in normal ventricular conduction and function. During 8 weeks of rapid DDD pacing, animals developed LV remodelling (confirmed with histology) with septal wall thinning ( 30%, p < 0.05), lateral wall thickening (+22%, p < 0.05), LV volume increase (+32%, p < 0.05), decrease of LV ejection fraction (-31%, p < 0.05), and functional mitral regurgitation. After 8 weeks, segmental pressure-strain-loops, representing regional myocardial work, were recorded. Switching from AAI to DDD decreased immediately work in the septum and increased it in the lateral wall ( 69 and +41%, respectively, p < 0.05). Global LV stroke work and dP/dtmax decreased (-27% and -25%, respectively, p < 0.05). CONCLUSIONS: Herein is developed a new sheep model with an asymmetrically remodelled LV. Simple pacemaker programming allows direct modulation of regional myocardial function and work. This model provides a new and valuable alternative for canine or porcine models and has the potential to become instrumental for investigating regional function and loading conditions on regional LV remodelling. PMID- 29570209 TI - Long-term outcomes of mitral valve annuloplasty versus subvalvular sparing replacement for severe ischemic mitral regurgitation. AB - BACKGROUND: Although practice guidelines recommend surgery for patients with severe chronic ischemic mitral regurgitation (CIMR), they do not specify whether to repair or replace the mitral valve. The purpose of this study was to evaluate the long-term outcomes in patients with severe CIMR undergoing mitral valve annuloplasty (MVA) versus subvalvular sparing mitral valve replacement (MVR). METHODS: 392 consecutive patients who underwent MVA or subvalvular sparing MVR for treatment of severe CIMR were retrospectively reviewed. RESULTS: After adjustment for baseline differences with multivariable regression analysis at 53 monthsfollow-up (interquartile range, 34-81 months), there was no significant difference between the two groups for risk of major adverse cardiac or cerebrovascular events (MACCE), cardiac death, or all-cause death. Propensity score matching extracted 77 pairs. During the follow-up, compared with the MVR group, both the left atrium and left ventricle end-diastolic diameter were markedly larger (p = 0.013 and p = 0.033, respectively), and the incidence of mitral regurgitation recurrence was significantly higher in the MVA group (p < 0.001). No significant difference was observed between the two propensity score matched groups in composite in-hospital outcomes, overall survival, freedom from cardiac death or MACCE, except subvalvular sparing MVR was associated with a lower incidence of hospitalization for heart failure than MVA (p = 0.015). CONCLUSIONS: Subvalvular sparing MVR is a suitable management of patients with severe CIMR, it is more favorable to ventricular remodeling and is associated with a lower incidence of hospitalization for heart failure than MVA. PMID- 29570211 TI - Valve in valve implantation of the CoreValve Evolut R in degenerated surgical aortic valves. AB - BACKGROUND: The new CoreValve Evolut R has an improved design to minimize paravalvular leak-age and allows repositioning of the valve. For patients with degenerated bioprosthetic aortic valves, transcatheter aortic valve implantation (TAVI) represents a less invasive option. Herein reported are valve-in-valve (ViV) implantations of this new valve. METHODS: A total of 26 patients (mean age 79.4 +/- 6.1 years, 17 males and 9 females) were treated for severe prosthesis stenosis (n = 9), severe regurgitation (n = 8) or severe combination of stenosis and regurgitation (n = 9). All patients underwent transthoracic echocardiography before and after ViV implantation. RESULTS: Valve-in-valve implantation of a CoreValve Evolut R was performed successfully in all pa-tients. The mean transaortic gradient for stenotic valves determined by transthoracic echocardiography was reduced significantly from 37.5 +/- 15.3 mmHg in patients with prosthesis stenosis to 16.3 +/- 8.2 mmHg (p < 0.001). In all cases with severe prosthesis regurgitation, regurgitation was reduced to none or mild. All cause mortality after 30 days was 0%. CONCLUSIONS: It was concluded that CoreValve Evolut R is well suited for ViV implantation. PMID- 29570210 TI - Medium and long-term prognosis of transcatheter aortic valve implantation from the perspective of left ventricular diastolic function. AB - BACKGROUND: The effects of left ventricular (LV) diastolic function are well known in cardiac surgery, but unclear in transcatheter aortic valve implantation (TAVI). The objective of this study was to examine the association of preoperative LV diastolic function with medium to long-term outcomes of TAVI. METHODS: Eighty patients who underwent TAVI were classified into grades I, II and III based on preoperative LV diastolic function. Findings related to cardiovascular outcomes after TAVI were extracted retrospectively from clinical and echocardiographic data and relationships with diastolic function were examined. RESULTS: The average follow-up was 529 days (interquartile range {IQR] 358-741 days). Cardiovascular events occurred in 17 cases, including 6 deaths, and were significantly associated with Euro II score (p = 0.043), albumin level (p = 0.026), coronary artery disease (CAD) (p = 0.017), and diastolic function (p < 0.001). The 360-day event-free rates were 89.5%, 89.5% and 37.5% for grades I, II and III (p = 0.00013). Median event-free survival (EFS) in grade III cases was 180 days. In a Cox proportional hazard model, LV diastolic dysfunction (hazard ratio [HR]3.99, 95% confidence interval [CI] 1.35-11.80, p = 0.012) and low albumin (HR 4.73, 95% CI 1.42-15.80, p = 0.012) were significant independent predictors of reduced EFS. CONCLUSIONS: Medium to long-term outcomes of TAVI were poorer in patients with deteriorated LV diastolic function, and outcomes in grade III cases were significantly worse than those in grade I and II cases. Preoperative LV diastolic function may be useful in prediction of outcomes after TAVI. PMID- 29570212 TI - How does the risk of cardiovascular death and cardiovascular risk factor profiles differ between socioeconomic classes in Poland: A country in transition. AB - BACKGROUND: Socioeconomic status (SES) is an important factor of cardiovascular diseases (CVD) development. A decline in death from CVD among subjects with high SES is observed in developed countries. The aim of this study was to assess differences in cardiovascular risk between socioeconomic classes in Poland, a country currently in transition. METHODS: A sample of 15200 people was drawn. A three stage selection was performed. Eventually, 6170 patients were examined (2013/2014). Data was collected using a questionnaire in face-to-face interviews, anthropometric data and blood tests were also obtained. Education was categorized as incomplete secondary, secondary and higher than secondary school. Monthly income per person was categorized as low (<= 1000 PLN), medium (1001-2000 PLN) and high (>= 2001 PLN). Education and income groups were analyzed by prevalence of CVD risk factors and high CVD risk (SCORE >= 5%). RESULTS: Higher education was associated with lower prevalence of all analyzed CVD risk factors (p < 0.001), having the highest income with lower prevalence of hypertension, currently smoking, obesity and lower HDL-cholesterol. Multivariable analysis showed that frequency of high CVD risk decreased with increasing education level (OR 0.61; 95% CI 0.49-0.76; p < 0.01), a similar favorable impact of higher income on high CVD risk was demonstrated in the whole group (OR 0.81; 95% CI 0.67 0.99; p = 0.04). CONCLUSIONS: SES is an independent predictor of high cardiovascular (CV) risk of death. A favorable impact on the prevalence of high CV risk was demonstrated for education and partly for income in the whole group. It may reflect a transition being undergone in Poland, moreover, it predicts how socioeconomic factors may generate health inequalities in other transitioning countries.

PMID- 29570214 TI - Distance learning for maternal and child health nurses and midwives in Mongolia: a qualitative evaluation. AB - BACKGROUND: Continuing education is vital for the development of the competencies of nurses and midwives. We analysed the effectiveness of a distance education programme for maternal and child health nurses and midwives in Mongolia, assessing its strengths and limitations and ways in which it could be improved. The aim of this research is to provide an analysis of the successes and failures of the programme, in order to improve future versions of this and similar programmes in Mongolia and elsewhere. METHODS: We carried out a qualitative descriptive study in Mongolia in August 2015. This consisted of three semi structured interviews and two focus groups in the Second National Hospital, Ulaanbaatar, and three semi-structured interviews and one focus group in Dornogovi Provincial Maternal Hospital, Sainshand, Dornogovi Province. In total, there were 22 participants in our research. Data from the interviews and focus groups were thematically coded and analysed using NVivo version 10. FINDINGS: The distance education programme is well received by participants. They suggest that it has improved their clinical practice and education in a number of areas, and are anxious for the programme to continue. A number of alterations would be necessary to improve both the quality of the programme and the ability of participants to foster change on the basis of what they have learnt. This provides challenges for both the programme organizers and the providers of maternal and child health services in Mongolia. IMPLICATIONS FOR NURSING AND/OR HEALTH POLICY: The success of the distance education programme suggests that collaborations of this type are a cost-effective method of disseminating best practice in policy and practice to improve the quality of care provided to mothers and children in low-resource settings. CONCLUSIONS: A distance education programme is vital to link maternal care providers in Mongolia to new trends in care. Mongolia's relative isolation means that this programme is particularly valuable there. However, the programme could work equally well in other developing country settings. PMID- 29570215 TI - Functional lifespans of xylem vessels: Development, hydraulic function, and post function of vessels in several species of woody plants. AB - PREMISE OF THE STUDY: Xylem vessels transition through different stages during their functional lifespan, including expansion and development of vessel elements, transition to vessel hydraulic functionality, and eventual transition to post-functionality. We used information on vessel development and function to develop a model of vessel lifespan for woody plants. METHODS: We examined vessel functional lifespan using repeated anatomical sampling throughout the growing season, combined with active-xylem staining to evaluate vessel hydraulic transport functionality. These data were combined with a literature review. The transitions between vessel functional lifespans for several species are illustrated, including grapevine (Vitis vinifera L., Vitaceae), English oak (Quercus robur L., Fagaceae), American chestnut [Castanea dentata (Marshall) Borkh.; Fagaceae], and several arid and semi-arid shrub species. KEY RESULTS: In intact woody plants, development and maturation of vessel elements may be gradual. Once hydraulically functional, vessel elements connect to form a vessel network that is responsible for bulk hydraulic flow through the xylem. Vessels become nonfunctional due to the formation of gas emboli. In some species and under some conditions, vessel functionality of embolized conduits may be restored through refilling. Blockages, such as tyloses, gels, or gums, indicate permanent losses in hydraulic functional capacity; however, there may be some interesting exceptions to permanent loss of functionality for gel-based blockages. CONCLUSIONS: The gradual development and maturation of vessel elements in woody plants, variation in the onset of functionality between different populations of vessels throughout the growing season, and differences in the timing of vessel transitions to post-functionality are important aspects of plant hydraulic function. PMID- 29570216 TI - Cardiac resynchronization therapy: A comparative analysis of mortality in African Americans and Caucasians. AB - BACKGROUND: Cardiac resynchronization therapy (CRT) is recommended in patients with heart failure, reduced left ventricular ejection fraction, and a prolonged QRS duration. African Americans are underrepresented in clinical trials and CRT is underutilized; consequently, the benefits and outcomes of CRT are not well defined. METHODS: We evaluated 294 patients, determined survival using Kaplan Meier analysis, and used Cox proportional hazards regression model to determine predictors of mortality. Propensity score-match analysis was applied to balance covariates in African Americans and Caucasians. RESULTS: The mean age for African Americans (n = 131) and Caucasians (n = 163) was 65 +/- 12 and 70 +/- 13 years (P = 0.0003). Mortality in African Americans was 28% compared to 37% in Caucasians (P = 0.14) over a median follow-up of 8.1 +/- 0.6 years. Survival was significantly reduced in African Americans and Caucasians with a glomerular filtration rate (GFR) < 60 (6.7 +/- 0.4, 95% confidence interval [CI]: 5.9-7.5 vs 8.6 +/- 0.5 CI: 7.7-9.5 years, P = 0.005), and those not treated with an aldosterone antagonist (7.1 +/- 0.4, 95% CI: 6.5-7.9 vs 8.7 +/- 0.6, 7.6-9.9 years, P = 0.04), respectively. Independent predictors of mortality were a GFR <60 and low left ventricular ejection fraction. In African Americans, ischemic cardiomyopathy (ICM) and lack of therapy with an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) were associated with increased mortality. CONCLUSIONS: Long-term survival benefit from CRT was similar in African Americans and Caucasians. A GFR < 60 and lack of therapy with an aldosterone antagonist were associated with decreased survival. Survival also was inversely related to the number of comorbidities. In African Americans, underutilization of an ACEI or ARB, and ICM were additional factors associated with increased mortality. PMID- 29570217 TI - Impact of apheresis automation on procedure quality and predictability of CD34+ cell yield. AB - Success of peripheral blood stem cell (PBSC) collections depends on patient biological parameters and stable apheresis device performance. We investigated product quality and factors influencing main apheresis procedure outcomes including CD34+ collection efficiency (CE), product volume or platelet CE. We also assessed different CD34+ cell yield prediction algorithms. Autologous PBSC collections by Spectra Optia from myeloma and lymphoma patients were analyzed. Complete blood count (CBC) from patient preprocedure and from collected products were assessed. (1) Product yield was calculated, (2) Product CBC was correlated with patient preprocedure variables, and (3) Predictions of CD34+ yields based on (a) product CD34+ cell concentration in samples after two or four chamber flushes or (b) traditional CE2 benchmark, were compared. 62 procedures in 41 patients were analyzed. 84% of all procedures were run without operator intervention. Median CD34+ CE2 was 56.9% (48.8%-65.2%) and quite stable irrespective of patient conditions, with minor influence from patient white blood cell (WBC) precounts (rs = -.47; P < .001). Platelet loss correlated with WBC precount (rs = .46; P < .001), product volume (rs = .71; P < .0001) and number of chambers collected (rs = .72; P < .0001). CD34+ cell yield was better predicted based on (a) product CD34+ cell concentration from samples after 2 and 4 chamber flushes, respectively (rs = .969; P < .0001 and rs = .9648; P < .0001) than based on (b) CE2 formula (rs = .8262, P < .0001). Spectra Optia provides good quality PBSC products with stable and predictable yield regardless of starting conditions. CD34+ sampling of product after few chamber flushes could be used to predict CD34+ yield. PMID- 29570218 TI - Analyzing linear spatial features in ecology. AB - The spatial analysis of dimensionless points (e.g., tree locations on a plot map) is common in ecology, for instance using point-process statistics to detect and compare patterns. However, the treatment of one-dimensional linear features (fiber processes) is rarely attempted. Here we appropriate the methods of vector sums and dot products, used regularly in fields like astrophysics, to analyze a data set of mapped linear features (logs) measured in 12 * 1-ha forest plots. For this demonstrative case study, we ask two deceptively simple questions: do trees tend to fall downhill, and if so, does slope gradient matter? Despite noisy data and many potential confounders, we show clearly that topography (slope direction and steepness) of forest plots does matter to treefall. More generally, these results underscore the value of mathematical methods of physics to problems in the spatial analysis of linear features, and the opportunities that interdisciplinary collaboration provides. This work provides scope for a variety of future ecological analyzes of fiber processes in space. PMID- 29570219 TI - Advanced glycation end-products suppress autophagic flux in podocytes by activating mammalian target of rapamycin and inhibiting nuclear translocation of transcription factor EB. AB - Insufficient autophagy in podocytes is related to podocyte injury in diabetic nephropathy (DN). Advanced glycation end-products (AGEs) are major factors of podocyte injury in DN. However, the role and mechanism of AGEs in autophagic dysfunction remain unknown. We investigated autophagic flux in AGE-stimulated cultured podocytes using multiple assays: western blotting, reverse transcription quantitative PCR, immunofluorescence staining, and electron microscopy. We also utilized chloroquine and a fluorescent probe to monitor the formation and turnover of autophagosomes. Mice of the db/db strain were used to model diabetes mellitus (DM) with high levels of AGEs. To mimic DM with normal levels of AGEs as a control, we treated db/db mice with pyridoxamine to block AGE formation. AGEs impaired autophagic flux in the cultured podocytes. Compared with db/db mice with normal AGEs but high glucose levels, db/db mice with high AGEs and high glucose levels exhibited lower autophagic activity. Aberrant autophagic flux was related to hyperactive mammalian target of rapamycin (mTOR), a major suppressor of autophagy. Pharmacologic inhibition of mTOR activity restored impaired autophagy. AGEs inhibited the nuclear translocation and activity of the pro-autophagic transcription factor EB (TFEB) and thus suppressed transcription of its several autophagic target genes. Conversely, TFEB overexpression prevented AGE-induced autophagy insufficiency. Attenuating mTOR activity recovered TFEB nuclear translocation under AGE stimulation. Co-immunoprecipitation assays further demonstrated the interaction between mTOR and TFEB in AGE-stimulated podocytes and in glomeruli from db/db mice. In conclusion, AGEs play a crucial part in suppressing podocyte autophagy under DM conditions. AGEs inhibited the formation and turnover of autophagosomes in podocytes by activating mTOR and inhibiting the nuclear translocation of TFEB. (c) 2018 The Authors.

PMID- 29570220 TI - CETP and LCAT Gene Polymorphisms Are Associated with High-Density Lipoprotein Subclasses and Acute Coronary Syndrome. AB - We evaluated whether CETP and LCAT gene polymorphisms are statistically associated with the high-density lipoprotein (HDL) size distribution, the cholesterol level of HDL subclasses, and the acute coronary syndrome (ACS) susceptibility. Two CETP gene polymorphisms (rs4783961 and rs708272) and one LCAT polymorphism (rs2292318) were genotyped by 5' exonuclease TaqMan assays in 619 patients with ACS and 607 control individuals. For HDL analysis, a subgroup of 100 healthy individuals was recruited; the HDL subclasses were separated via ultracentrifugation and polyacrylamide gradient gel electrophoresis under native conditions. Under a dominant model, the G allele of the rs708272 polymorphism was associated with an increased risk of ACS (odds ratios [OR] = 1.45, corrected p value [pCDom ] = 0.036). The linkage disequilibrium analysis showed that one of the eight possible combinations was associated with the risk of developing ACS (OR = 1.52, pC = 0.02), which suggests that it may contribute to coronary atherosclerosis. The rs708272 G allele carriers had a lower concentration of cholesterol associated with the HDL2a and HDL3a subclasses when compared with subjects carrying the A allele. Carriers of LCAT rs2292318 A allele showed a lower concentration of high-density lipoprotein-cholesterol (HDL-C) in comparison to the GG genotype; the cholesterol associated with the each one of the five HDL subclasses was significantly lower in rs2292318 A than in GG subjects. In summary, this study demonstrates that the rs708272 polymorphism is associated with a heightened risk of developing ACS. In addition, we report the association of the rs708272 and rs2292318 polymorphisms with HDL-C levels and HDL subclasses.

PMID- 29570221 TI - Effects of calcium and its interaction with phosphorus on the nutrient status and growth of three Lupinus species. AB - Phosphorus (P)-deficiency symptoms are known for Lupinus species grown in calcareous soil, but we do not know if this is due to a high calcium (Ca) availability or a low P availability in the soil. To address this problem, we explored both the effects of Ca and its interactions with P on nutrient status and growth of three Lupinus species. Two Ca-sensitive genotypes (L. angustifolius L. P26723 and L. cosentinii Guss. P27225) and two Ca-tolerant genotypes (L. angustifolius L. cv Mandelup and L. pilosus Murr. P27440) were grown hydroponically at two P (0.1 and 10 MUM) and three Ca (0.1, 0.6 and 6 mM) levels. Leaf symptoms and biomass were recorded, whole leaf and root nutrient concentrations were analysed, and leaf cellular P and Ca concentrations were determined. Phosphorus-deficiency symptoms were only observed in the Ca-sensitive genotypes. Among all the genotypes in this study, the Ca-tolerant L. pilosus showed an ability to maintain stable leaf Ca and P concentrations whereas the Ca tolerant L. angustifolius cv Mandelup did not maintain a stable whole leaf Ca concentration, but maintained a low cytosolic Ca2+ concentration through effective Ca compartmentation. However, the two Ca-sensitive genotypes, L. angustifolius P26723 and L. cosentinii, did not exhibit an ability to maintain a stable whole leaf Ca concentration or effectively compartmentalise Ca. Therefore, having the capacity to maintain a stable whole leaf Ca concentration or effectively compartmentalising Ca in leaves are likely critical for Lupinus species to be Ca tolerant. PMID- 29570223 TI - An investigation of the monoamine oxidase inhibition properties of pyrrolo[3,4 f]indole-5,7-dione and indole-5,6-dicarbonitrile derivatives. AB - Hit, Lead & Candidate Discovery In recent studies, we have shown that pyrrolo[3,4 f]indole-5,7-dione and indole-5,6-dicarbonitrile derivatives act as good potency in vitro inhibitors of the monoamine oxidase (MAO) enzymes. To expand on these series and to further derive structure-activity relationships (SARs) for MAO inhibition, in the present study we synthesized additional homologs and related analogs of these chemical classes. Analyzes of the MAO inhibition properties of the synthesized compounds show that among the pyrrolo[3,4-f]indole-5,7-dione derivatives good potency MAO inhibitors exist as exemplified by 10, which possesses IC50 values for the inhibition of MAO-A and MAO-B of 0.023 and 0.178 uM, respectively. Among thirteen pyrrolo[3,4-f]indole-5,7-diones, nine compounds exhibit IC50 values for the inhibition of an MAO isoform in the submicromolar range. It may be concluded that active MAO inhibitors, such as 10 represent suitable leads for the development of drugs for neurodegenerative and neuropsychiatric disorders such as Parkinson's disease and depression. MAO inhibitors are also of interest for the treatment of prostate cancer, certain types of cardiomyopathies and Alzheimer's disease. PMID- 29570224 TI - A rare missense mutation in GJB3 (Cx31G45E) is associated with a unique cellular phenotype resulting in necrotic cell death. AB - Erythrokeratodermia variabilis et progressiva (EKV-P) is caused by mutations in either the GJB3 (Cx31) or GJB4 genes (Cx30.3). We identified a rare GJB3 missense mutation, c.134G>A (p.G45E), in two unrelated patients and investigated its cellular characteristics. Expression of Cx31G45E-GFP caused previously undescribed changes within HeLa cells and HaCaT cells, a model human keratinocyte cell line. Cx31WT-GFP localised to the plasma membrane, but expression of Cx31G45E-GFP caused vacuolar expansion of the endoplasmic reticulum (ER), the mutant protein accumulated within the ER membrane and disassembly of the microtubular network occurred. No ER stress responses were evoked. Cx31WT-myc-myc 6xHis and Cx31G45E-GFP co-immunoprecipitated, indicative of heteromeric interaction, but co-expression with Cx31WT-mCherry, Cx26 or Cx30.3 did not mitigate the phenotype. Cx31 and Cx31G45E both co-immunoprecipitated with Cx43, indicating the ability to form heteromeric connexons. WT-Cx31 and Cx43 assembled into large gap junction plaques at points of cell-to-cell contact; Cx31G45E restricted the ability of Cx43 to reach the plasma membrane in both HaCaT cells and HeLa cells stably expressing Cx43 where the proteins strongly co-localised with the vacolourised ER. Cell viability assays identified an increase in cell death in cells expressing Cx31G45E-GFP, which FACS analysis determined was necrotic. Blocking connexin channel function with 18alpha-glycyrrhetinic acid did not completely rescue necrosis or prevent propidium iodide uptake, suggesting that expression of Cx31G45E-GFP damages the cellular membrane independent of its channel function. Our data suggest that entrapment of Cx43 and necrotic cell death in the epidermis could underlie the EKV skin phenotype.

AB - PREMISE OF THE STUDY: Recent research has highlighted the importance of living tissue in wood. Polyploidization can impact amounts and arrangements of living cells in wood, potentially leading to increased drought tolerance. Tetraploid variants were created from the apple cultivar Malus *domestica 'Gala' (Gala-4x), and their vulnerability to drought-induced cavitation and their hydraulic capacitance were compared to those of their diploid predecessors (Gala-2x). Assuming a positive correlation between polyploidy and drought tolerance, we hypothesized lower vulnerability and higher capacitance for the tetraploid. METHODS: Vulnerability to drought-induced cavitation and the hydraulic capacitance were quantified through acoustic emission and continuous weighing of shoots during a bench-top dehydration experiment. To underpin the hydraulic trait results, anatomical variables such as vessel area, conduit diameter, cell wall reinforcement, and ray and vessel-associated parenchyma were measured. KEY RESULTS: Vulnerability to drought-induced cavitation was intrinsically equal for both ploidy variants, but Gala-4x proved to be more vulnerable than Gala-2x during the early phase of desiccation as was indicated by its significantly lower air entry value. Higher change in water content of the leafy shoot, higher amount of parenchyma, and larger vessel area and size resulted in a significantly higher hydraulic capacitance and efficiency for Gala-4x compared to Gala-2x. CONCLUSIONS: Both ploidy variants were typified as highly sensitive to drought induced cavitation, with no significant difference in their overall drought vulnerability. But, when water deficit is short and moderate, Gala-4x may delay a drought-induced decrease in performance by trading hydraulic safety for increased release of capacitively stored water from living tissue. PMID- 29570229 TI - Ecological data for western Indian Ocean tuna. AB - Tuna are marine apex predators that inhabit the tropical and sub-tropical waters of the Indian Ocean where they support socially and economically important fisheries. Key component of pelagic communities, tuna are bioindicator species of anthropogenic and climate-induced changes through modifications of the structure and related energy-flow of food webs and ecosystems. The IndianEcoTuna dataset provides a panel of ecological tracers measured in four soft tissues (white muscle, red muscle, liver, gonads) from 1,364 individuals of four species, i.e., the albacore (ALB, Thunnus alalunga), the bigeye (BET, T. obesus), the skipjack (SKJ, Katsuwomus pelamis), and the yellowfin (YFT, T. albacares), collected throughout the western Indian Ocean from 2009 to 2015. Sampling was carried out during routine monitoring programs, at sea by observers onboard professional vessels or at landing. For each record, the type of fishing gear, the conservation mode, as well as the fishing date and catch location are provided. Individuals were sampled to span a wide range of body sizes: 565 ALB with fork length from 58 to 118 cm, 155 BET from 29.5 to 173 cm, 304 SKJ from 30 to 74 cm, and 340 YFT from 29 to 171.5 cm. The IndianEcoTuna dataset combines: (1) 9,512 records of carbon and nitrogen stable isotopes (percent element weights, delta13 C and delta15 N values) in 1,185 fish, (2) 887 concentrations of total proteins in 242 fish, (3) 8,356 concentrations of total lipids and three lipid classes (triacylglycerols TAG; phospholipids PL; sterols ST) in 695 fish, and (4) 1,150 and 1,033 profiles of neutral and polar fatty acids in 397 and 342 fish, respectively. Information on sex and weights of the whole fish, gonads, liver and stomach is provided. Because of the essential trophic role and wide-ranging of tuna in marine systems, and the large panel of tropho-energetic tracers and derived-key quantitative parameters provided (e.g., niche width, trophic position, condition indices), the IndianEcoTuna dataset should be of high interest for global and regional research on marine trophic ecology and food web analysis, as well as on the impacts of anthropogenic changes on Indian Ocean marine ecosystems.

PMID- 29570230 TI - Association between the age of solid food introduction and eczema: A systematic review and a meta-analysis. AB - INTRODUCTION: Eczema is a common childhood ailment responsible for a considerable disease burden. Both timing of introduction to solid food and allergenic food are believed to be related to childhood eczema. Despite the growing body of evidence, the relationship between timing of any solid food introduction (allergenic and/or non-allergenic) and development of eczema has not previously been systematically reviewed. METHODS: PubMed and EMBASE databases were searched using food and eczema terms. Two authors selected papers according to the inclusion criteria and extracted information on study characteristics and measures of association. Meta analyses were performed after grouping studies according to the age and type of exposure. RESULTS: A total of 17 papers met the inclusion criteria, reporting results from 16 study populations. Of these, 11 were cohort studies, 2 case controls, 1 cross-sectional study and 2 randomized controlled trials. Limited meta-analyses were performed due to heterogeneity between studies. Timing of solid food introduction was not associated with eczema. One randomized controlled trial provided weak evidence of an association between early allergenic (around 4 months) food introduction and reduced risk of eczema. CONCLUSIONS: The available evidence is currently insufficient to determine whether the timing of introduction of any solid food influences the risk of eczema. PMID- 29570232 TI - STX2 is a causative gene for nonobstructive azoospermia. AB - STX2 encodes a sulfoglycolipid transporter. Although Stx2 nullizygosity is known to cause spermatogenic failure in mice, STX2 mutations have not been identified in humans. Here, we performed STX2 mutation analysis for 131 Japanese men clinically diagnosed with nonobstructive azoospermia. As a result, we identified a homozygous frameshift mutation [c.8_12delACCGG, p.(Asp3Alafs*8)] in one patient. The mutation-positive patient exhibited loss-of-heterozygosity for 58.4 Mb genomic regions involving STX2, suggesting possible parental consanguinity. The patient showed azoospermia, relatively small testes, and a mildly elevated follicle stimulating hormone level, but no additional clinical features. Testicular histology of the patient showed universal maturation arrest and multinucleated spermatocytes, which have also been observed in mice lacking Stx2. PCR-based cDNA screening revealed wildtype STX2 expression in various tissues including the testis. Our results indicate that STX2 nullizygosity results in nonsyndromic maturation arrest with multinucleated spermatocytes, and accounts for a small fraction of cases with nonobstructive azoospermia. PMID- 29570233 TI - Direct production of dihydroxylated sesquiterpenoids by a maize terpene synthase. AB - The astounding structural and biological diversities of the large class of terpenoid natural products are imparted by both their complex hydrocarbon backbones and further elaboration by the addition of multiple hydroxyl groups, which provide both solubility and specific binding properties. While the role of terpene synthases (TPSs) in generating hydrocarbons with complex backbones is well known, these also are known to generate (singly) hydroxylated products by the addition of water prior to terminating deprotonation. Here a maize sesquiterpene synthase was unexpectedly found to generate dually hydroxylated products directly from (E,E)-farnesyl diphosphate, primarily eudesmane-2,11-diol, along with two closely related structural isomers. The unprecedented formation of these diols was proposed to proceed via initial addition of water to a germacradienyl+ intermediate, followed by protonation of the internal carbon-6,7 double-bond in the resulting hedycarol, with subsequent cyclization and further addition of water to an eudesmolyl+ intermediate. Evidence for the proposed mechanism was provided by labeling studies, as well as site-directed mutagenesis, based on structural modeling, which identified an active site phenylalanine required for the protonation and further elaboration of hedycaryol. This dihydroxylated sesquiterpenoid synthase was specifically expressed in maize roots and induced by pathogen infection, with its major enzymatic product only detected in root exudates or infected roots, suggesting a role in defense. Regardless of the ultimate metabolic fate or physiological role of these diols, this report not only reveals an unanticipated extension of the catalytic prowess of TPSs, but also provides insight into the underlying enzymatic mechanism. PMID- 29570231 TI - A Comparative In Vivo Study of Albumin-Coated Paclitaxel Nanocrystals and Abraxane. AB - Nanoparticulate drug carriers exploit the enhanced permeability of tumor vasculature to achieve selective delivery of chemotherapeutic drugs. For this purpose, nanoparticles (NPs) need to circulate with a long half-life, enter tumors via the permeable vasculature and stay in tumors via favorable interactions with tumor cells. To fulfill these requirements, albumin-coated nanocrystal formulation of paclitaxel (PTX), Cim-F-alb, featuring high drug loading content, physical stability in serum, and surface-bound albumin in its native conformation is prepared. The pharmacokinetic and biodistribution (PK/BD) profiles of Cim-F-alb in a mouse model of B16F10 melanoma show that Cim-F-alb exhibits a longer plasma half-life and a greater PTX deposition in tumors than Abraxane by ~1.5 and ~4.6 fold, respectively. Biolayer interferometry analysis indicates that Cim-F-alb has less interaction with serum proteins than nanocrystals lacking albumin coating, indicating the protective effect of the surface-bound albumin against opsonization in the initial deposition phase. With the advantageous PK/BD profiles, Cim-F-alb shows greater and longer-lasting anticancer efficacy than Abraxane at the equivalent dose. This study demonstrates the significance of controlling circulation stability and surface property of NPs in efficient drug delivery to tumors and enhanced anticancer efficacy. PMID- 29570234 TI - Pilot study utilizing Fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography for glycolytic phenotyping of canine mast cell tumors. AB - The goal of this prospective pilot study was to use naturally occurring canine mast cell tumors of various grades and stages as a model for attempting to determine how glucose uptake and markers of biologic behavior are correlated. It was hypothesized that enhanced glucose uptake, as measured by 2-[fluorine 18]fluoro-d-glucose-positron emission tomography/computed tomography (F18 FDG PET CT), would correlate with histologic grade. Dogs were recruited for this study from a population referred for treatment of cytologically or histologically confirmed mast cell tumors. Patients were staged utilizing standard of care methods (abdominal ultrasound and three view thoracic radiographs), followed by a whole body F18 FDG PET-CT. Results of the F18 FDG PET-CT were analyzed for possible metastasis and standard uptake value maximum (SUVmax ) of identified lesions. Incisional or excisional biopsies of the accessible mast cell tumors were obtained and histology performed. Results were then analyzed to look for a possible correlation between the grade of mast cell tumors and SUVmax . A total of nine animals were included in the sample. Findings indicated that there was a correlation between grade of mast cell tumors and SUVmax as determined by F18 FDG PET-CT (p-value = 0.073, significance <= 0.1). Based on the limited power of this study, it is felt that further research to examine the relationship between glucose utilization and biologic aggressiveness in canine mast cell tumors is warranted. This study was unable to show that F18 FDG PET-CT was a better staging tool than standard of care methods. PMID- 29570235 TI - Adjustable Intermolecular Interactions Allowing 2D Transition Metal Dichalcogenides with Prolonged Scavenging Activity for Reactive Oxygen Species. AB - There is an increasing demand for control over the dimensions and functions of transition metal dichalcogenides (TMDs) in aqueous solution toward biological and medical applications. Herein, an approach for the exfoliation and functionalization of TMDs in water via modulation of the hydrophobic interaction between poly(epsilon-caprolactone)-b-poly(ethylene glycol) (PCL-b-PEG) and the basal planes of TMDs is reported. Decreasing the hydrophobic PCL length of PCL-b PEG from 5000 g mol-1 (PCL5000 ) to 460 g mol-1 (PCL460 ) significantly increases the exfoliation efficiency of TMD nanosheets because the polymer-TMD hydrophobic interaction becomes dominant over the polymer-polymer interaction. The TMD nanosheets exfoliated by PCL460 -b-PEG5000 (460-WS2 , 460-WSe2 , 460-MoS2 , and 460-MoSe2 ) show excellent and prolonged scavenging activity for reactive oxygen species (ROS), but each type of TMD displays a different scavenging tendency against hydroxyl, superoxide, and 2,2'-azino-bis(3-ethylbenzothiazoline-6 sulfonic acid) radicals. A mechanistic study based on electron paramagnetic resonance spectroscopy and density functional theory simulations suggests that radical-mediated oxidation of TMDs and hydrogen transfer from the oxidized TMDs to radicals are crucial steps for ROS scavenging by TMD nanosheets. As-prepared 460-TMDs are able to effectively scavenge ROS in HaCaT human keratinocytes, and also exhibit excellent biocompatibility. PMID- 29570236 TI - Allied health weekend service provision in Australian rehabilitation units. AB - OBJECTIVES: To determine current Australian allied health rehabilitation weekend service provision and to identify perceived barriers to and facilitators of weekend service provision. METHODS: Senior physiotherapists from Australian rehabilitation units completed an online cross-sectional survey exploring current service provision, staffing, perceived outcomes, and barriers and facilitators to weekend service provision. RESULTS: A total of 179 (83%) eligible units responded, with 94 facilities (53%) providing weekend therapy. A Saturday service was the most common (97%) with the most frequent service providers being physiotherapists (90%). Rehabilitation weekend service was perceived to increase patient/family satisfaction (66%) and achieve faster goal attainment (55%). Common barriers were budgetary restraints (66%) and staffing availability (54%), with facilitators including organisational support (76%), staff availability (62%) and staff support (61%). CONCLUSION: Despite increasing evidence of effectiveness, only half of Australian rehabilitation facilities provide weekend services. Further efforts are required to translate evidence from clinical trials into feasible service delivery models. PMID- 29570238 TI - Relationship between individual and family characteristics and psychosocial factors in persons with familial pancreatic cancer. AB - OBJECTIVE: Describe relationships between self-reported personal demographics or familial characteristics and psychosocial outcomes (Patient Reported Outcome Measurement Information System Global Health, Impact of Event Scale-Revised [pancreatic cancer risk-related distress], cancer risk perception, and cancer worry) in participants with inherited or familial pancreatic cancer risk. METHODS: A multisite cross sectional survey of adults with elevated pancreatic cancer risk based on family history. All variables were summarized with descriptive statistics. To assess univariate associations, t test and chi square/Fisher's exact test were used, and backward model selection was used in multivariable analysis. RESULTS: Respondents (N = 132) reported moderate to high frequency of cancer worry and 59.3% perceived a 50% or more perceived lifetime risk for pancreatic cancer, which far exceeds objective risk estimates. Cancer worry was associated with female gender (P = .03) and pancreatic cancer risk specific distress (P = .05). Higher-risk perception was associated with having a high school education or less (P = .001), higher distress (P = .02), and cancer worry (P = .008) and family cancer death experience (P = .02). Higher distress was associated with experience as a caregiver to a seriously ill family member in the past 5 years (P = .006). CONCLUSIONS: Individuals with inherited or familial pancreatic cancer risk experience cancer worry, distress, and have increased risk perception, particularly in the period following caring for a loved one with cancer. Routine evaluation of distress in this setting, as well as the development of supportive care resources, will help support patients living with risk for pancreatic cancer. PMID- 29570237 TI - Cytomegalovirus resistance in CD34+ -selected hematopoietic cell transplant recipients. AB - BACKGROUND: Cytomegalovirus (CMV) viremia after CD34+ -selected hematopoietic stem cell transplant (HCT) often requires prolonged antiviral therapy. We report rates and outcomes of resistant CMV in a contemporary cohort of CD34+ -selected HCT recipients managed preemptively. METHODS: We retrospectively reviewed 220 consecutive, CMV-seropositive recipients (R+), who received CD34+ -selected HCT at Memorial Sloan Kettering Cancer Center between June 2010 and December 2014. Patients were monitored by quantitative CMV PCR and were treated preemptively. CMV resistance was tested by a genotypic assay. RESULTS: One hundred and sixty one (73%) patients developed CMV viremia and 47 (29% of viremic and 21% of total patients) had CMV resistance testing by one-year from HCT. CMV resistance was confirmed in 19 (12% of viremic and 9% of total) patients and was identified >3 months from HCT in 90% of patients. Twelve patients had mutations in UL97 only; the remaining 7 patients had mutations in UL54 only or UL54 and UL97. By 1 year from HCT, 11 of 19 (58%) patients with mutations had CMV end-organ disease. CMV related mortality in patients with resistance was 42%. CONCLUSIONS: Nine percent of CMV R+, CD34+ -selected HCT recipients had resistant CMV by 1 year from HCT. Of 19 patients with resistant CMV, 58% had CMV end-organ disease and 42% died of CMV. Effective strategies for CMV prevention and restoration of CMV immunity are needed for CD34+ -selected HCT. PMID- 29570239 TI - Metal-Free Cyclization of ortho-Nitroaryl Ynamides and Ynamines towards Spiropseudoindoxyls. AB - An efficient metal-free cascade reaction between 1-dibromovinyl-2-nitro substituted arenes and secondary amines results in the formation of polycyclic pseudoindoxyls in a single step. The reaction mechanism leading to these fused ring systems was investigated, and is believed to involve the initial formation of nitroarylated ynamines/ynamides. These intermediates cycloisomerize towards N alkenyl-tethered 2-aminoisatogens via a carbene intermediate as demonstrated by QTAIM (quantum theory of atoms in molecules) and ELF (electron localization function) analysis. A subsequent intramolecular dipolar cycloaddition afforded the title compounds. PMID- 29570240 TI - Unambiguous identification and characterization of a long-term human metabolite of dehydrochloromethyltestosterone. AB - In doping control analysis, the characterization of urinary steroid metabolites is of high interest for a targeted and long-term detection of prohibited anabolic androgenic steroids (AAS). In this work, the structure of a long-term metabolite of dehydrochloromethyltestosterone (DHCMT) was elucidated. Altogether, 8 possible metabolites with a 17alpha-methyl-17beta-hydroxymethyl - structures were synthesized and compared to a major DHCMT long-term metabolite detected in reference urine excretion samples.

AB - INTRODUCTION: An increased risk of cardiovascular complications has been defined in community-acquired pneumonia (CAP), but limited data is available for patients with severe CAP. OBJECTIVE: The aim of the present study was to define the prevalence, characteristics, risk factors and impact on mortality of acute cardiac events in patients with severe CAP during short and long term. METHOD: This investigation was a multicenter, retrospective cohort sudy of patients with severe CAP. Cardiac events were defined as cardiac arrhytmia, congestive heart failure and myocardial infarction. A logistic regression analysis was performed to identify predictors for acute cardiac events and mortality. RESULTS: Of 373 patients (mean age 68 +/- 16, 61.4% male), 56 (15%) developed a cardiac event (43 arrhythmia, 11 congestive heart failure and 2 myocardial infarction). Patients who developed an acute cardiac event were older, had more severe disease, pleural effusion, hypoalbuminemia, hyponatremia and more acidosis. Also, beta-blocker and diuretic use were more significant in these patients. In-hospital mortality was significantly higher in patients who developed cardiac events (29.6% vs 11%, P < .001). According to the logistic regression analysis, haloperidol, vasopressor or diuretic use, hypoalbuminemia and age were the predictors for acute cardiac events. Acute cardiac events were significantly associated with in-hospital mortality (OR 2.1; 95%CI 1.03-4.61, P = .04), but not associated with 90-day mortality. CONCLUSION: Our findings demonstrated that acute cardiac events are seen in a substantial proportion of patients with severe CAP and their occurence significantly associated with in-hospital mortality. PMID- 29570242 TI - Germline but not somatic de novo mutations are common in human congenital diaphragmatic hernia. AB - OBJECTIVES: Congenital diaphragmatic hernia (CDH) is a developmental defect of the diaphragm that causes high newborn morbidity and mortality. CDH is considered to be a multifactorial disease, with strong evidence implicating genetic factors. Although recent studies suggest the biological role of deleterious germline de novo variants, the effect of gene variants specific to the diaphragm remains unclear, and few single genes have been definitively implicated in human disease. METHODS: We performed genome sequencing on 16 individuals with CDH and their unaffected parents, including 10 diaphragmatic samples. RESULTS: We did not detect damaging somatic mutations in diaphragms, but identified germline heterozygous de novo functional mutations of 14 genes in nine patients. Although the majority of these genes are not known to be associated with CDH, one patient with CDH and cardiac anomalies harbored a frameshift mutation in NR2F2 (aka COUP TFII), generating a premature truncation of the protein. This patient also carried a missense variant predicted to be damaging in XIRP2 (aka Myomaxin), a transcriptional target of MEF2A. Both NR2F2 and MEF2A map to chromosome 15q26, where recurring de novo deletions and unbalanced translocations have been observed in CDH. CONCLUSIONS: Somatic variants are not common in CDH. To our knowledge, this is the second case of a germline de novo frameshift mutation in NR2F2 in CDH. Since NR2F2 null mice exhibit a diaphragmatic defect, and XIRP2 is implicated in cardiac development, our data suggest the role of these two variants in the etiology of CDH, and possibly cardiac anomalies.

PMID- 29570244 TI - Metabolic Propensity for Weight Gain Unmasked by Overfeeding. PMID- 29570246 TI - The Obesity Paradox: A Misleading Term That Should Be Abandoned. AB - The term "obesity paradox" is a figure of speech, not a scientific term. The term has no precise definition and has been used to describe numerous observations that have little in common other than the finding of an association of obesity with a favorable outcome. The terminology has led to misunderstandings among researchers and the public alike. It's time for authors and editors to abandon the use of this term. Simply labeling counterintuitive findings as the "obesity paradox" adds no value. Unexpected findings should not be viewed negatively; such findings can lead to new knowledge, better treatments, and scientific advances. PMID- 29570245 TI - Nonnutritive Sweeteners in Weight Management and Chronic Disease: A Review. AB - OBJECTIVE: The objective of this review was to critically review findings from recent studies evaluating the effects of nonnutritive sweeteners (NNSs) on metabolism, weight, and obesity-related chronic diseases. Biologic mechanisms that may explain NNS effects will also be addressed. METHODS: A comprehensive review of the relevant scientific literature was conducted. RESULTS: Most cross sectional and prospective cohort studies report positive associations between NNS consumption, body weight, and health conditions, including type 2 diabetes, cardiovascular disease, and nonalcoholic fatty liver disease. Although findings in cellular and rodent models suggest that NNSs have harmful effects on metabolic health, most randomized controlled trials in humans demonstrate marginal benefits of NNS use on body weight, with little data available on other metabolic outcomes. CONCLUSIONS: NNS consumption is associated with higher body weight and metabolic disease in observational studies. In contrast, randomized controlled trials demonstrate that NNSs may support weight loss, particularly when used alongside behavioral weight loss support. Additional long-term, well-controlled intervention studies in humans are needed to determine the effects of NNSs on weight, adiposity, and chronic disease under free-living conditions. PMID- 29570247 TI - Young Adult Cancer: Influence of the Obesity Pandemic. AB - OBJECTIVE: The purpose of this article is to review the association of the obesity pandemic with appearance of cancers in young adults under age 50 and to define potential mechanisms by which obesity may accelerate the development of malignancy. METHODS: A comprehensive narrative review was performed to integrate preclinical, clinical, and epidemiologic evidence describing the association of obesity with cancer in young adults based on a search of PubMed and Google databases. RESULTS: Results from more than 100 publications are summarized. Although they differ in age groups analyzed and incidence of obesity, sufficient data exists to suggest an influence of the obesity pandemic on the increase of cancer among young adults. CONCLUSIONS: Cancer in young adults is occurring with increasing frequency. Overweight and obesity have become major public health issues reaching pandemic proportions. Excess weight is associated with increased cancer risk, morbidity, and mortality. Multiple murine models indicate that obesity not only increases cancer incidence but also accelerates its development. Thus, the possibility exists that overweight and obesity may be contributing to the appearance of specific malignancies at younger ages. This prospect, in association with the worldwide expansion of obesity, suggests an impending explosive increase in obesity-associated cancers in young adults.

PMID- 29570248 TI - Free-Living Responses in Energy Balance to Short-Term Overfeeding in Adults Differing in Propensity for Obesity. AB - OBJECTIVE: Free-living adaptive responses to short-term overfeeding (OF) were explored as predictors of longitudinal weight change in adults classified as having obesity resistance (OR) or obesity proneness (OP) based on self identification and personal/family weight history. METHODS: Adults identified as OP (n = 21; BMI: 23.8 +/- 2.5 kg/m2 ) and OR (n = 20; BMI: 20.2 +/- 2.1 kg/m2 ) completed 3 days of eucaloric feeding (EU; 100% of energy needs) and 3 days of OF (140% of energy needs). Following each condition, adaptive responses in physical activity (PA), total daily energy expenditure, ad libitum energy intake, and energy balance were objectively measured for 3 days in a free-living environment. Body mass and composition were measured annually by using dual-energy x-ray absorptiometry for 5 years. Adaptive responses to OF were correlated with 5-year changes in body mass and composition. RESULTS: Increases in sedentary time correlated with longitudinally measured changes in fat mass (r = 0.34, P = 0.04) in the cohort taken as a whole. Those with OP reduced their levels of PA following OF, whereas those with OR maintained or increased their PA. No other variables were found to correlate with weight gain. CONCLUSIONS: Failure to decrease sedentary behavior following short-term OF is one mechanism that may be contributing to fat mass gain. PMID- 29570250 TI - Current Knowledge of Obesity Treatment Guidelines by Health Care Professionals. AB - OBJECTIVE: The objective of this study was to assess health care professionals' knowledge of evidence-based guidelines for the nonsurgical treatment of obesity. METHODS: A nationally representative sample of internists, family practitioners, obstetricians/gynecologists, and nurse practitioners completed a web-based survey between June 9 and July 1, 2016 (n = 1,506). RESULTS: Only 16% of respondents indicated that obesity counseling should be provided approximately twice monthly in an individual or group setting for at least 6 months, in accordance with United States Preventive Services Task Force and Centers for Medicare and Medicaid Services guidelines. Only 15% of respondents identified BMI >= 27 kg/m2 with an obesity-associated comorbid condition as the appropriate indication to prescribe pharmacotherapy for patients. Two-thirds of respondents indicated that it is appropriate to continue long-term pharmacotherapy under conditions inconsistent with evidence-based guidelines, with nearly one-quarter indicating that obesity medications should never be prescribed beyond 3 months regardless of weight loss. CONCLUSIONS: These findings suggest that provider understanding of appropriate clinical care for obesity is inconsistent with evidence-based recommendations. As coverage for behavioral counseling services and pharmacotherapy expands, it is imperative that health care professionals understand how to effectively leverage these treatment modalities to optimize health outcomes for patients with obesity.

PMID- 29570254 TI - Diagnostic accuracy of multiparametric magnetic resonance imaging in detecting extracapsular extension in intermediate and high - risk prostate cancer. AB - OBJECTIVES: To evaluate the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) as a predictor of extracapsular extension (ECE) and unfavorable Gleason score (GS) in patients with intermediate and high-risk prostate cancer (PCa). MATERIALS AND METHODS: Patients with clinically localized PCa who underwent radical prostatectomy (RP) and had preoperative mp-MRI between May-2011 and December-2013. Mp-MRI was evaluated according to the European Society of Urogenital Radiology MRI prostate guidelines by two different readers. Histopathological RP results were the standard reference. RESULTS: 79 patients were included; mean age was 61 and median preoperative prostate-specific antigen (PSA) 7.0. On MRI, 28% patients had ECE evidenced in the mp-MRI, 5% seminal vesicle invasion (SVI) and 4% lymph node involvement (LNI). At RP, 39.2% had ECE, 26.6% SVI and 12.8% LNI. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of mp-MRI for ECE were 54.9%, 90.9%, 76%, 81% and 74.1% respectively; for SVI values were 19.1%, 100%, 77.3%, 100% and 76.1% respectively and for LNI 20%, 98.4%, 86.7%, 66.7% and 88.7%. CONCLUSIONS: Major surgical decisions are made with digital rectal exam (DRE) and ultrasound studies before the use of Mp MRI. This imaging study contributes to rule out gross extraprostatic extension (ECE, SVI, LNI) without competing with pathological studies. The specificity and NPV are reasonable to decide surgical approach. A highly experienced radiology team is needed to provide accurate estimations of tumor extension and aggressiveness.

AB - INTRODUCTION: Paraganglioma is an extremely rare catecholamine-producing tumor during pregnancy. Paraganglioma carries high risks of fetal and maternal mortality during pregnancy. We report a pregnant woman with paraganglioma in the second trimester. CASE DESCRIPTION: A 24-year-old pregnant woman presented with severe hypertension in the 17th week of gestation. Hormonal examination and Magnetic Resonance Imaging (MRI) confirmed the diagnosis of extra adrenal pheochromocytoma (paraganglioma). She underwent laparoscopic tumor excision successfully. CONCLUSIONS: A high index of suspicion is needed to diagnose paraganglioma in a pregnant patient with hypertension. Laparoscopic tumor removal for paraganglioma seems to be a feasible and safe procedure during pregnancy. PMID- 29570257 TI - Retroperitoneoscopic resection of retroperitoneal nonadrenal ganglioneuromas: our technique and clinical outcomes. AB - OBJECTIVE: To report our experience of retroperitoneoscopic technique in semi lateral decubitus position for the retroperitoneal nonadrenal ganglioneuromas in 18 patients, and to evaluate its clinical outcomes. MATERIALS AND METHODS: From January 2012 to May 2016, 18 patients with retroperitoneal nonadrenal ganglioneuromas underwent retroperitoneoscopic resection. With the patients in semi-lateral decubitus position, a 4-port retroperitoneal approach was used. Data were collected on the tumor size, tumor location, perioperative outcomes, pathology, and lastknown disease status. We reviewed the operative videos to identify surgical tips and tricks. RESULTS: All procedures were carried out successfully without converting to open surgery. The tumors had an average size of 5.2cm. The mean operative time was 86.5 min, with a mean estimated blood loss of 85.4mL. There were three patients suffering from intraoperative complications. Postoperatively, all patients achieved an uneventful recovery; the mean postoperative hospital stay was 5.5 days. The postoperative pathology revealed to be retroperitoneal ganglioneuromas. With a mean follow-up of 39.5 months, all patients were recurrence free. The review of the operative videos revealed several tips and tricks, including keeping peritoneum and posterior Gerota fascia intact to provide a favorable operative exposure of tumors, and placing the harmonic scalpel through different ports during tumor dissection. CONCLUSIONS: With the patient in semi-lateral decubitus position and a 4-port retroperitoneal approach, retroperitoneoscopic resection of retroperitoneal nonadrenal ganglioneuroma is a feasible, effective, and safe procedure. This approach has distinct advantages including direct access to the tumor, optimal exposure of tumor and less intraperitoneal interference.

PMID- 29570259 TI - Prognostic significance of the dynamic changes of systemic inflammatory response in metastatic renal cell carcinoma. AB - PURPOSE: To elucidate the prognostic value of systemic inflammatory response in patients with metastatic renal cell carcinoma (mRCC) who are treated with sunitinib, we evaluated the prognostic role of C-reactive protein (CRP) kinetics. This study also compared prognostic models containing CRP kinetics and neutrophil to-lymphocyte ratio (NLR) kinetics. MATERIALS AND METHODS: A consecutive cohort of 94 patients with mRCC who were treated with sunitinib was retrospectively included from Fudan University Shanghai Cancer Center. According to dynamic changes in CRP and the NLR, patients were divided into three groups for analysis of CRP and NLR kinetics. The associations between survival and potential prognostic factors were assessed. The incremental value of prognostication was evaluated. RESULTS: A significant difference (P<0.001) in overall survival (OS) was observed among the three groups of CRP kinetics. The median OS of the non elevated group was nearly 1.3-fold longer than that of the normalized group (33.0 vs. 26.3 months), and two times longer than that of the non-normalized group (33.0 vs. 14.0 months). Multivariate analysis showed that CRP and NLR kinetics were independent prognostic indicators. The model containing CRP kinetics had a better predictive accuracy than that with NLR kinetics, which was supported by the C-index (0.731 vs. 0.684) and the likelihood ratio chi2 test (79.9% vs. 44.9%). CONCLUSION: Our study suggests that dynamic changes in CRP can better predict survival in patients with mRCC who are treated with sunitinib. Routine assessment of CRP before and after targeted therapy would help identify patients at risk of a poor outcome. PMID- 29570260 TI - The history of varicocele: from antiquity to the modern ERA. AB - Men have most likely been affected by varicocele since the assumption of the upright position. In De Medicina, written during the first century AD, Celsus credits the Greeks with the first description of a varicocele, and he recorded his own acute observation: "The veins are swollen and twisted over the testicle, which becomes smaller". Celsus himself is credited with the distinction between varicocele (dilation of surface veins) and "cirsocele" (dilation of deep veins). There has been a long history of treatment attempts and failures, some of which are remarkably strange, that have sometimes culminated in tragedy, as in the case of French professor Jacques-Mathieu Delpech (1772- 1832). Although some questions regarding the etiopathology and treatment of varicocele remain unanswered, a succession of more or less conservative attempts involving all medical cultures has been performed throughout history. The report by W.S. Tulloch in 1952 brought varicocele into the era of modern evidence-based medicine, and varicocele surgery finally progressed beyond the aim of merely relieving scrotal pain and swelling. From 1970 to 2000, varicocelectomies gained worldwide attention for the treatment of male infertility. Several innovative procedures to correct varicoceles began to appear in the world's literature as interventional radiology, microsurgery, laparoscopy, and robotics, while comprehensive review articles were also published on the subject of varicocelectomies. Microsurgery is nowadays used worldwide and it can be considered to be the gold standard for correcting infertility linked to varicocele. PMID- 29570261 TI - Objective measurements of the penile angulation are significantly different than self-estimated magnitude among patients with penile curvature. AB - INTRODUCTION: The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie's disease (PD) and congenital penile curvature (CPC). MATERIALS AND METHODS: Wee analysed a cohort of 88 consecutive patients seeking medical help for either CPC or PD. All patients were invited to provide a self made drawing of their penis in erection in order to obtain self-provided description of the deformity. An objective measurement of the deformity was also performed drawing two intersecting lines through the center of the distal and proximal straight section of the penile shaft. RESULTS: Our findings showed significant differences between patient self-estimation and the objective measurements of the penile angulation performed by trained experts, with only 32% of patients correctly assessing their own curvature. Overall, patients tended to overestimate (56%) their degree of curvature, but the results are different in patients with PD than those with CPC. In the 60 men (68%) who did not accurately assess their curvature, PD patients generally overestimated their curvature versus CPC patients (67% vs 16%). On the contrary CPC patients underestimated their curvature compared to PD (42% vs. 4%). CONCLUSION: In order to improve patients' satisfaction rates, the surgeon needs to take into consideration the patient's perception of the deformity when planning the type of surgical correction. PMID- 29570262 TI - Polygamy, sexual behavior in a population under risk for prostate cancer diagnostic: an observational study from the Black Sea Region in Turkey. AB - AIM: Although prostate cancer (PCa) is the most common cancer type in men, a replaceable risk factor has not yet been established. In our study, we assessed the relationship between the number of sexual partners, age of first sexual experience and age of first masturbation and prostate cancer incidence. MATERIALS AND METHODS: In Ordu University Department of Urology between January 2013 and September 2016, in PSA elevation and rectal examination, patients with prostate biopsy were evaluated due to nodule palpation in the prostate. At younger ages and at present, their first masturbation ages, first sexual debut ages, and total sexual partner numbers were recorded. The correlation between the obtained data and PCa frequency was evaluated. RESULTS: The study included 146 patients with PCa identified on biopsy and 171 patients with benign biopsy results who answered the questions. 66.7% of the ones whose biopsy results were benign and 40.6% of cancer suspects had only one sexual partner. The median number of sexual partners was 1+/-4 (1-100) in the benign group and 2+/-6 (1-500) in the malignant group (p=0.039). There was a negative correlation between age of first sexual debut and number of partners (r: -0,479; p<0.001). CONCLUSION: In our study, it appears that there may be an association between the number of sexual partners and prostate cancer in the patient group with PSA level above 4ng/mL. Avoidance of sexual promiscuity or participation in protected sex may be beneficial to protect against prostate cancer. PMID- 29570263 TI - Direct Writing and Characterization of Three-Dimensional Conducting Polymer PEDOT Arrays. AB - Direct writing is an effective and versatile technique for three-dimensional (3D) fabrication of conducting polymer (CP) structures. It is precisely localized and highly controllable, thus providing great opportunities for incorporating CPs into microelectronic array devices. Herein we demonstrate 3D writing and characterization of poly(3,4-ethylenedioxythiophene)-polystyrenesulfonate (PEDOT:PSS) pillars in an array format, by using an in-house-constructed variant of scanning ion conductance microscopy (SICM). CP pillars with different aspect ratios were successfully fabricated by optimizing the writing parameters: pulling speed, pulling time, concentration of the polymer solution, and the micropipette tip diameter. Especially, super high aspect ratio pillars of around 7 MUm in diameter and 5000 MUm in height were fabricated, indicating a good capability of this direct writing technique. Additions of an organic solvent and a cross linking agent contribute to a significantly enhanced water stability of the pillars, critical if the arrays were to be used in biologically relevant applications. Surface morphologies and structural analysis of CP pillars were characterized by scanning electron microscopy and Raman spectroscopy, respectively. Electrochemical properties of the individual pillars of different heights were examined by cyclic voltammetry using a double-barrel micropipette as an electrochemical cell. Exceptional mechanical properties of the pillars, such as high flexibility and robustness, were observed when bent by applying a force. The 3D pillar arrays are expected to provide versatile substrates for functionalized and integrated biological sensing and electrically addressable array devices. PMID- 29570264 TI - Enzyme Prodrug Therapy Achieves Site-Specific, Personalized Physiological Responses to the Locally Produced Nitric Oxide. AB - Nitric oxide (NO) is a highly potent but short-lived endogenous radical with a wide spectrum of physiological activities. In this work, we developed an enzymatic approach to the site-specific synthesis of NO mediated by biocatalytic surface coatings. Multilayered polyelectrolyte films were optimized as host compartments for the immobilized beta-galactosidase (beta-Gal) enzyme through a screen of eight polycations and eight polyanions. The lead composition was used to achieve localized production of NO through the addition of beta-Gal-NONOate, a prodrug that releases NO following enzymatic bioconversion. The resulting coatings afforded physiologically relevant flux of NO matching that of the healthy human endothelium. The antiproliferative effect due to the synthesized NO in cell culture was site-specific: within a multiwell dish with freely shared media and nutrients, a 10-fold inhibition of cell growth was achieved on top of the biocatalytic coatings compared to the immediately adjacent enzyme-free microwells. The physiological effect of NO produced via the enzyme prodrug therapy was validated ex vivo in isolated arteries through the measurement of vasodilation. Biocatalytic coatings were deposited on wires produced using alloys used in clinical practice and successfully mediated a NONOate concentration dependent vasodilation in the small arteries of rats. The results of this study present an exciting opportunity to manufacture implantable biomaterials with physiological responses controlled to the desired level for personalized treatment. PMID- 29570265 TI - Integrated Analysis of Exosomal Protein Biomarkers on Alternating Current Electrokinetic Chips Enables Rapid Detection of Pancreatic Cancer in Patient Blood. AB - Pancreatic ductal adenocarcinoma (PDAC) typically has nonspecific symptoms and is often found too late to treat. Because diagnosis of PDAC involves complex, invasive, and expensive procedures, screening populations at increased risk will depend on developing rapid, sensitive, specific, and cost-effective tests. Exosomes, which are nanoscale vesicles shed into blood from tumors, have come into focus as valuable entities for noninvasive liquid biopsy diagnostics. However, rapid capture and analysis of exosomes with their protein and other biomarkers have proven difficult. Here, we present a simple method integrating capture and analysis of exosomes and other extracellular vesicles directly from whole blood, plasma, or serum onto an AC electrokinetic microarray chip. In this process, no pretreatment or dilution of sample is required, nor is it necessary to use capture antibodies or other affinity techniques. Subsequent on-chip immunofluorescence analysis permits specific identification and quantification of target biomarkers within as little as 30 min total time. In this initial validation study, the biomarkers glypican-1 and CD63 were found to reflect the presence of PDAC and thus were used to develop a bivariate model for detecting PDAC. Twenty PDAC patient samples could be distinguished from 11 healthy subjects with 99% sensitivity and 82% specificity. In a smaller group of colon cancer patient samples, elevated glypican-1 was observed for metastatic but not for nonmetastatic disease. The speed and simplicity of ACE exosome capture and on chip biomarker detection, combined with the ability to use whole blood, will enable seamless "sample-to-answer" liquid biopsy screening and improve early stage cancer diagnostics. PMID- 29570266 TI - Enhancing Antibody Serodiagnosis Using a Controlled Peptide Coimmobilization Strategy. AB - Antigen immunoreactivity is often determined by surface regions defined by the 3D juxtapositions of amino acids stretches that are not continuous in the linear sequence. As such, mimicking an antigen immunoreactivity by means of putative linear peptide epitopes for diagnostic purposes is not trivial. Here we present a straightforward and robust method to extend the reach of immune-diagnostic probes design by copresenting peptides belonging to the same antigenic surface. In this case study focused on a computationally predicted Zika virus NS1 protein putative antigenic region, we reached a diagnostic confidence by the oriented and spatially controlled coimmobilization of peptide sequences found adjacent within the protein fold, that cooperatively interacted to provide enhanced immunoreactivity with respect to single linear epitopes. Through our method, we were able to differentiate Zika infected individuals from healthy controls. Remarkably, our strategy fits well with the requirements to build high-throughput screening platforms of linear and mixed peptide libraries, and it could possibly facilitate the rapid identification of conformational immunoreactive regions. PMID- 29570268 TI - A Fluorescent Probe for Stimulated Emission Depletion Super-Resolution Imaging of Vicinal-Dithiol-Proteins on Mitochondrial Membrane. AB - Realizing the significant roles of vicinal-dithiol proteins (VDPs) in maintaining the cellular redox homeostasis and their implication in many diseases, we synthesized a smart arsenate based fluorescent probe 1 which can preferentially target the mitochondrial membrane-bound vicinal dithiol proteins (VDPs), especially voltage-dependent anion channel (VDAC2). The probe targetability was demonstrated by in vitro studies such as colocalization, stimulated emission depletion (STED) super-resolution imaging, proteomic MS/MS analysis, and Western blot analysis. The probe represents a rare example of fluorescence labeling of mitochondrial membrane-bound VDPs and can provide a new way to construct VDPs specific fluorescent probes to gain deeper understanding of their roles in mitochondrial-related disorders. PMID- 29570269 TI - Shear Adhesion of Tapered Nanopillar Arrays. AB - Tapered nanopillars with various cross sections, including cone-shaped, stepwise, and pencil-like structures (300 nm in diameter at the base of the pillars and 1.1 MUm in height), are prepared from epoxy resin templated by nanoporous anodic aluminum oxide (AAO) membranes. The effect of pillar geometry on the shear adhesion behavior of these nanopillar arrays is investigated via sliding experiments in a nanoindentation system. In a previous study of arrays with the same geometry, it was shown that cone-shaped nanopillars exhibit the highest adhesion under normal loading while stepwise and pencil-like nanopillars exhibit lower normal adhesion strength due to significant deformation of the pillars that occurs with increasing indentation depth. Contrary to the previous studies, here, we show that pencil-like nanopillars exhibit the highest shear adhesion strength at all indentation depths among three types of nanopillar arrays and that the shear adhesion increases with greater indentation depth due to the higher bending stiffness and closer packing of the pencil-like nanopillar array. Finite element simulations are used to elucidate the deformation of the pillars during the sliding experiments and agree with the nanoindentation-based sliding measurements. The experiments and finite element simulations together demonstrate that the shape of the nanopillars plays a key role in shear adhesion and that the mechanism is quite different from that of adhesion under normal loading. PMID- 29570270 TI - Cascade Amplification-Mediated In Situ Hot-Spot Assembly for MicroRNA Detection and Molecular Logic Gate Operations. AB - MicroRNAs (miRNAs) play important roles in many biological processes and are associated with various diseases, especially cancers. Combination of technological developments such as nanomaterials, functional enzyme-mediated reactions, and DNA nanotechnology holds great potential for high-performance detection of miRNAs in molecular diagnostic systems. In this work, we have fabricated a cascade signal amplification platform through integrating duplex specific nuclease (DSN)-assisted target recycling with catalytic hairpin assembly (CHA) reaction for the detection of microRNA-141 (miR-141). The target recycling process driven by DSN results in highly amplified translation of target miRNA to single-stranded connector DNA fragments. The CHA reaction is further initiated by connector DNAs using hairpin-modified gold nanoparticles (HP-AuNPs) as the sensing unit, leading to the formation of AuNP network architecture on the electrode for electrochemical and photoelectrochemical detection of miR-141 in signal-on and signal-off modes, respectively. The developed electrochemical biosensor exhibits a detection limit down to 25.1 aM miR-141 (60 copies in 4 MUL sample) and excellent selectivity to discriminate a single base-mismatched sequence and other miRNAs. This assay is also applied to the determination of miR 141 in total RNAs extracted from human breast cancer cells (MDA-MB-231), confirming the applicability of this method for absolute quantification of specific miRNAs in real-world samples. Furthermore, two-input AND and INHIBIT (INH) logic gates are constructed to detect miRNAs. In particular, the AND gate achieves cell-specific gate activation based on expression profiles of miR-141 and microRNA-21 (miR-21). Therefore, our proposed cascade amplification platform has great potential applications in miRNA-related clinical diagnostics and biochemical research. PMID- 29570267 TI - Imaging Action Potential in Single Mammalian Neurons by Tracking the Accompanying Sub-Nanometer Mechanical Motion. AB - Action potentials in neurons have been studied traditionally by intracellular electrophysiological recordings and more recently by the fluorescence detection methods. Here we describe a label-free optical imaging method that can measure mechanical motion in single cells with a sub-nanometer detection limit. Using the method, we have observed sub-nanometer mechanical motion accompanying the action potential in single mammalian neurons by averaging the repeated action potential spikes. The shape and width of the transient displacement are similar to those of the electrically recorded action potential, but the amplitude varies from neuron to neuron, and from one region of a neuron to another, ranging from 0.2-0.4 nm. The work indicates that action potentials may be studied noninvasively in single mammalian neurons by label-free imaging of the accompanying sub-nanometer mechanical motion. PMID- 29570271 TI - Establishment of Novel Biosynthetic Pathways for the Production of Salicyl Alcohol and Gentisyl Alcohol in Engineered Escherichia coli. AB - Salicyl alcohol and gentisyl alcohol are two important phenolic alcohols that possess significant biological activities and pharmaceutical properties. Here, we report establishment of novel biosynthetic pathways for microbial production of salicyl alcohol and gentisyl alcohol from renewable feedstocks. We first examined the promiscuity of the carboxylic acid reductase CAR toward salicylic acid and 2,5-DHBA, which enabled efficient synthesis of salicyl alcohol and gentisyl alcohol. Then, we employed a novel salicylic acid 5-hydroxylase to achieve 2,5 DHBA production from salicylic acid. After that, the de novo biosynthetic pathways were assembled and optimized by programming the carbon flux into the shikimate pathway. The final titers of salicyl alcohol and gentisyl alcohol reached to 594.4 mg/L and 30.1 mg/L, respectively. To our knowledge, this work achieved microbial production of salicyl alcohol and gentisyl alcohol for the first time. Our present study also demonstrated application of enzyme promiscuity to establish non-natural biosynthetic pathways for the production of high-value compounds.

Chemical and/or genetic modifications of the Hb introduce varied structural and conformational constraint on the molecule that resulted in proteins with diverse allosteric responses, nitrosative and oxidative side reactions. Here, we present for the first time a comprehensive biochemical and biophysical comparison of human, bovine, and genetically engineered HBOCs that have been tested in humans. We evaluate oxygen equilibrium and ligand binding kinetics under different experimental conditions as well as their autoxidation kinetics, redox reactions, and heme release. We determined the effects of HBOCs on cellular redox states and mitochondrial respiration. Taken together, these experiments provide a better understanding of the relationship between the structure-function and oxidative reactivity of these proteins. One can therefore select independently among these diverse properties to engineer a safe and effective HBOC with improved biochemical/biophysical characteristics.

AB - Electrochemical aptasensors generally include three elements, that is, recognition element, signal-transformation element, and regeneration element. In this study, a new adenosine triphosphate (ATP) aptasensor is developed by combining three elements into one DNA oligonucleotide chain. In the DNA oligonucleotide chain, DNA aptamer is used as the recognition element, ferrocene group attached at the 3'-end of the aptamer is used as the signal-transformation element, and azobenzene moiety embedded into the DNA chain is used as the regeneration element. In addition to the similar analytical properties with the traditional ones, the aptasensor developed here is easily regenerated with UV light irradiation. The current response recorded on the aptasensor increases with increasing the concentration of ATP in the incubation solution and is linear with the logarithm of ATP concentration in the range from 1 nM to 100 MUM. The limit of detection is 0.5 nM (S/N = 3). The basal level of ATP in the rat brain cortex microdialysate is determined to be 21.33 +/- 4.1 nM ( n = 3). After being challenged with ATP, the aptasensor could be readily regenerated by UV-light irradiation for more than seven cycles. The regeneration of the aptasensor is proposed to be regulated by conversing azobenzene from its trans to cis form under UV irradiation.

AB - Designing and synthesizing nanomaterials with high coverages of active sites is one of the most-pivotal factors in the construction of state-of-the-art electrocatalysts with high performance. Herein, we proposed a facile in situ templated method for the fabrication of oxygen-species-modified nitrogen-doped carbon nanosheets (O-N-CNs). The epoxy oxygen and ketene oxygen combined with graphitic-nitrogen defects in O-N-CNs gave more active sites for the oxygen reduction reaction (ORR) and the oxygen-evolution reaction (OER), as proven via theoretical and experimental results, while the carbonyl-oxygen and epoxy-oxygen species showed more efficient electrocatalytic activity for the hydrogen evolution reaction (HER). Hence, the O-N-CNs showed highly active electrocatalytic performance toward ORR, OER, and HER. More importantly, the superior multifunctional electrocatalytic activity of O-N-CNs allowed their use in the construction of Zn-air batteries to power the corresponding water splitting cells. This work can offer an understanding of underlying mechanisms of oxygen species on N-doped carbon materials toward multiple electrocatalysis and facilitate the engineering of electrocatalysts for energy-storage and -conversion devices. PMID- 29570275 TI - Structural Characterization of a Heparan Sulfate Pentamer Interacting with LAR Ig1-2. AB - Leukocyte common antigen-related (LAR) protein is one of the type IIa receptor protein tyrosine phosphatases (RPTPs) that are important for signal transduction in biological processes, including axon growth and regeneration. Glycosaminoglycan chains, including heparan sulfate (HS) and chondroitin sulfate (CS), act as ligands that regulate LAR signaling. Here, we report the structural characterization of the first two immunoglobulin domains (Ig1-2) of LAR interacting with an HS pentasaccharide (GlcNS6S-GlcA-GlcNS3,6S-IdoA2S-GlcNS6S OME, fondaparinux) using multiple solution-based NMR methods. In the course of the study, we extended an assignment strategy useful for sparsely labeled proteins expressed in mammalian cell culture supplemented with a single type of isotopically enriched amino acid ([15N]-Lys in this case) by including paramagnetic perturbations to NMR resonances. The folded two-domain structure for LAR-Ig1-2 seen in previous crystal structures has been validated in solution using residual dipolar coupling data, and a combination of chemical shift perturbation on titration of LAR-Ig1-2 with fondaparinux, saturation transfer difference (STD) spectra, and transferred nuclear Overhauser effects (trNOEs) have been employed in the docking program HADDOCK to generate models for the LAR fondaparinux complex. These models are further analyzed by postprocessing energetic analysis to identify key binding interactions. In addition to providing insight into the ligand interaction mechanisms of type IIa RPTPs and the origin of opposing effects of CS and HS ligands, these results may assist in future design of therapeutic compounds for nervous system repair. PMID- 29570276 TI - Surprising Sequence Effects on GU Closure of Symmetric 2 * 2 Nucleotide RNA Internal Loops. AB - GU base pairs are important RNA structural motifs and often close loops. Accurate prediction of RNA structures relies upon understanding the interactions determining structure. The thermodynamics of some 2 * 2 nucleotide internal loops closed by GU pairs are not well understood. Here, several self-complementary oligonucleotide sequences expected to form duplexes with 2 * 2 nucleotide internal loops closed by GU pairs were investigated. Surprisingly, nuclear magnetic resonance revealed that many of the sequences exist in equilibrium between hairpin and duplex conformations. This equilibrium is not observed with loops closed by Watson-Crick pairs. To measure the thermodynamics of some 2 * 2 nucleotide internal loops closed by GU pairs, non-self-complementary sequences that preclude formation of hairpins were designed. The measured thermodynamics indicate that some internal loops closed by GU pairs are unusually unstable. This instability accounts for the observed equilibria between duplex and hairpin conformations. Moreover, it suggests that future three-dimensional structures of loops closed by GU pairs may reveal interactions that unexpectedly destabilize folding. PMID- 29570278 TI - Peptide-Based Sandwich Immunoassay for the Quantification of the Membrane Transporter Multidrug Resistance Protein 1. AB - Multitransmembrane proteins are notoriously difficult to analyze. To date, rapid, and cost-efficient detection methods are lacking and only mass spectrometry-based systems allow reliable quantification of these proteins. Here, we present a novel type of sandwich immunoassay that is capable of sensitively detecting multidrug resistance protein 1 (MDR1), a prototypic 12-transmembrane-domains transporter. In a first assay step, complex samples are enzymatically fragmented into peptides as routinely done for mass spectrometry. A proteotypic peptide derived from MDR1 was chosen and antibodies targeting this peptide were used to build a sandwich immunoassay. Validation of the optimized assay showed good sensitivity, reproducibility and it allowed reliable quantification of MDR1; cross-validation by mass spectrometry demonstrated the applicability for routine analyses in clinical and pharmaceutical research. MDR1 was quantified in primary human renal cell carcinoma and corresponding normal tissue and down-regulation or expression loss was found in tumor tissue corroborating its importance in drug resistance and efficacy. PMID- 29570279 TI - Doxycycline Prophylaxis for Bacterial Sexually Transmitted Infections: Promises and Perils. AB - Despite their high global incidence, sexually transmitted infections (STIs) remain a neglected area of research. Increased rates of STIs have been reported in particular among men who have sex with men (MSM) probably because of the advances in the treatment and prophylaxis of human immunodeficiency virus (HIV) infection with a decrease in condom use. A recent report among MSM showed that the use of postexposure prophylaxis with doxycycline could dramatically reduce the incidence of chlamydia and syphilis but not of gonorrhea. The long-term consequences of this strategy are yet unknown, especially the risk of selection and dissemination of syphilis and chlamydia strains with doxycycline resistance, which has not been reported yet. PMID- 29570277 TI - Magnetic Particle Imaging-Guided Heating in Vivo Using Gradient Fields for Arbitrary Localization of Magnetic Hyperthermia Therapy. AB - Image-guided treatment of cancer enables physicians to localize and treat tumors with great precision. Here, we present in vivo results showing that an emerging imaging modality, magnetic particle imaging (MPI), can be combined with magnetic hyperthermia into an image-guided theranostic platform. MPI is a noninvasive 3D tomographic imaging method with high sensitivity and contrast, zero ionizing radiation, and is linearly quantitative at any depth with no view limitations. The same superparamagnetic iron oxide nanoparticle (SPIONs) tracers imaged in MPI can also be excited to generate heat for magnetic hyperthermia. In this study, we demonstrate a theranostic platform, with quantitative MPI image guidance for treatment planning and use of the MPI gradients for spatial localization of magnetic hyperthermia to arbitrarily selected regions. This addresses a key challenge of conventional magnetic hyperthermia-SPIONs delivered systemically accumulate in off-target organs ( e.g., liver and spleen), and difficulty in localizing hyperthermia results in collateral heat damage to these organs. Using a MPI magnetic hyperthermia workflow, we demonstrate image-guided spatial localization of hyperthermia to the tumor while minimizing collateral damage to the nearby liver (1-2 cm distance). Localization of thermal damage and therapy was validated with luciferase activity and histological assessment. Apart from localizing thermal therapy, the technique presented here can also be extended to localize actuation of drug release and other biomechanical-based therapies. With high contrast and high sensitivity imaging combined with precise control and localization of the actuated therapy, MPI is a powerful platform for magnetic based theranostics. PMID- 29570280 TI - Anionic Carbosilane Dendrimers Destabilize the GP120-CD4 Complex Blocking HIV-1 Entry and Cell to Cell Fusion. AB - Cell-to-cell transmission is the most effective pathway for the spread of human immunodeficiency virus (HIV-1). Infected cells expose virus-encoded fusion proteins on their surface as a consequence of HIV-1 replicative cycle that interacts with noninfected cells through CD4 receptor and CXCR4 coreceptor leading to the formation of giant multinucleated cells known as syncytia. Our group previously described the potent activity of dendrimers against CCR5-tropic viruses. Nevertheless, the study of G1-S4, G2-S16, and G3-S16 dendrimers in the context of X4-HIV-1 tropic cell-cell fusion referred to syncytium formation remains still unknown. These dendrimers showed a suitable biocompatibility in all cell lines studied and our results demonstrated that anionic carbosilane dendrimers G1-S4, G2-S16, and G3-S16 significantly inhibit the X4-HIV-1 infection, as well as syncytia formation, in a dose dependent manner. We also demonstrated that G2-S16 and G1-S4 significantly reduced syncytia formation in HIV-1 Env-mediated cell-to-cell fusion model. Molecular modeling and in silico models showed that G2-S16 dendrimer interfered with gp120-CD4 complex and demonstrated its potential use for a treatment. PMID- 29570281 TI - Porous Anionic Uranyl-Organic Networks for Highly Efficient Cs+ Adsorption and Investigation of the Mechanism. AB - Exploitation of new materials for the removal of long-lived and highly radioactive actinides and their fission products produced in the nuclear fuel cycle is crucial for radionuclide management. Here, two rare porous anionic uranyl-organic frameworks (UOFs) have been successfully synthesized by a judicious combination of the tetratopic carboxylate ligand 1,3,6,8-tetrakis( p benzoic acid)pyrene (H4TBAPy) and D3 h-symmetrical triangular [UO2(COO)3]-. The resulting two compounds exhibit different architectures, albeit with similar coordination modes. Of interest is that they have excellent adsorption performance on Cs+ from aqueous solution. The high removal efficency would make them promising in applications of radioactive waste management. Notably, the framework of compound 2, [(CH3)2NH2]4[(UO2)4(TBAPy)3].22DMF.37H2O is sufficiently robust to allow the accessibility of intriguing single crystals of a Cs+-adsorbed derivative, which helps to elucidate the adsorption mechanism. The structural, bonding, and spectroscopic properties of the above compounds are examined using relativistic density functional theory (DFT). It is found that the adsorption toward cesium on UOFs is energetically favored, which features largely ionic bonds and is dominated by electrostatic attraction. PMID- 29570282 TI - Effect of Intercalated Water on Potassium Ion Transport through Kv1.2 Channels Studied via On-the-Fly Free-Energy Parametrization. AB - We introduce a two-dimensional version of the method called on-the-fly free energy parametrization (OTFP) to reconstruct free-energy surfaces using Molecular Dynamics simulations, which we name OTFP-2D. We first test the new method by reconstructing the well-known dihedral angles free energy surface of solvated alanine dipeptide. Then, we use it to investigate the process of K+ ions translocation inside the Kv1.2 channel. By comparing a series of two-dimensional free energy surfaces for ion movement calculated with different conditions on the intercalated water molecules, we first recapitulate the widely accepted knock-on mechanism for ion translocation and then confirm that permeation occurs with water molecules alternated among the ions, in accordance with the latest experimental findings. From a methodological standpoint, our new OTFP-2D algorithm demonstrates the excellent sampling acceleration of temperature accelerated molecular dynamics and the ability to efficiently compute 2D free energy surfaces. It will therefore be useful in large variety complex biomacromolecular simulations. PMID- 29570283 TI - Quantum Yields, Surface Quenching, and Passivation Efficiency for Ultrasmall Core/Shell Upconverting Nanoparticles. AB - We synthesized and characterized a set of ultrasmall hexagonal-phase NaGdF4: 20% Yb3+, 2% Er3+ upconversion nanoparticles with core diameters of 3.7 +/- 0.5 nm. In order to assess passivation effects and the influence of possible core-shell intermixing and to identify optimum particle structures for combined imaging in the visible and near-infrared (vis-NIR: 410-850 nm) and short-wave infrared (SWIR: 1520 nm), NaYF4 shells of varying thicknesses (monolayer to 10 nm) were introduced and the influence of this parameter on the upconversion and downshifting photoluminescence of these particles was studied at different excitation power densities. This included excitation power-dependent emission spectra, slope factors, quantum yields, and excited state decay kinetics. These measurements revealed enhancement factors of the upconversion quantum yield of >10 000 in the low power region and an excitation power density-independent quantum yield of the downshifted emission at 1520 nm between 0.1 and 14%. The optimized shell thickness for combined vis and SWIR imaging was identified as 5 nm. Moreover, lifetimes and quantum yields can be continuously tuned by shell thickness which can be exploited for lifetime multiplexing and encoding. The fact that we did not observe a saturation of the upconversion quantum yield or the excited state decay kinetics with increasing shell thickness is ascribed to a strong intermixing of the active core with the inert shell during the shelling procedure. This indicates the potential of spectroscopic tools to detect cation intermixing. PMID- 29570284 TI - Substrate Directed Asymmetric Reactions. AB - Historically, reagent controlled reactions (mechanism controlled reactions) have played a significant role in the asymmetric synthesis of complex structures. In contrast, today's asymmetric synthesis is greatly dependent on substrate directed approaches. In this approach, a polar functional group, namely, a "directing group", in the vicinity of the reactive site inside the substrate has been documented to preassociate with the chiral catalyst, which exerts stereodirecting influence by directing the reacting partner toward one of the enantiotopic faces of the reaction center. Those reactions usually proceed through exceptionally ordered transition states and result in extraordinary levels of stereoselection. Within the last four decades, the substrate directed approach has become an indispensible tool for the preparation of complex chiral frameworks starting directly from relatively simple achiral substrate molecules via asymmetric induction or various resolution techniques or both. Likewise, the substrate directed approach has been applied to functionalize enantiopure substrates bearing pre-exisiting stereocenters into complex structures as a single diastereomer. A classical example is Sharpless asymmetric epoxidation of allylic alcohols in which the free hydroxy function acts as an active anchor to a dimeric Ti-catalyst that controls the stereochemical outcome of the epoxidation process by transferring the oxidant enantioselectively. The principal aim of the present review is to give a general overview of substrate directed asymmetric transformations, a topic that has not yet been documented in the form of a concise review of recently developed approaches. Due to the large number of related applications, only recent advances that have been documented within the last two decades have been reviewed. Furthermore, in the current review, we have mainly highlighted asymmetric reactions that are controlled by abundant and frequently used directing groups such as hydroxy, amide, and sulfonamide groups. In addition, selected examples of a few important substrate-directed chemo-, regio-, and diastereoselective reactions have also been included in this review. PMID- 29570285 TI - Synthesis of Pyrimidine Fused Quinolines by Ligand-Free Copper-Catalyzed Domino Reactions. AB - Herein, we report two novel methods for the synthesis of pyrimidine fused quinolines using a one-pot C-C and C-N bond forming strategy from the reaction of 6-aminouracils with 2-bromobenzaldehydes or 2-bromobenzyl bromide derivatives in the presence of 10 mol % CuCl2 without using any ligand. The reaction of 2 bromobenzaldehyde or its derivatives with 6-aminouracils in the presence of K2CO3 as base and a catalytic amount of CuCl2 in DMF medium under microwave heating conditions provides corresponding pyrimidine fused quinoline derivatives in good yields within 30 min. Alternatively, pyrimidine fused quinoline derivatives have been synthesized from the reaction of 2-bromobenzyl bromides with 6-aminouracil derivatives in the presence of molecular oxygen, CuCl2 (10 mol %), and K2CO3 as base in DMF under reflux conditions. Structures of all the products were unambiguously confirmed by spectroscopic techniques and by recording single crystal XRD of 3a. PMID- 29570287 TI - Uncertain Environmental Footprint of Current and Future Battery Electric Vehicles. AB - The future environmental impacts of battery electric vehicles (EVs) are very important given their expected dominance in future transport systems. Previous studies have shown these impacts to be highly uncertain, though a detailed treatment of this uncertainty is still lacking. We help to fill this gap by using Monte Carlo and global sensitivity analysis to quantify parametric uncertainty and also consider two additional factors that have not yet been addressed in the field. First, we include changes to driving patterns due to the introduction of autonomous and connected vehicles. Second, we deeply integrate scenario results from the IMAGE integrated assessment model into our life cycle database to include the impacts of changes to the electricity sector on the environmental burdens of producing and recharging future EVs. Future EVs are expected to have 45-78% lower climate change impacts than current EVs. Electricity used for charging is the largest source of variability in results, though vehicle size, lifetime, driving patterns, and battery size also strongly contribute to variability. We also show that it is imperative to consider changes to the electricity sector when calculating upstream impacts of EVs, as without this, results could be overestimated by up to 75%. PMID- 29570286 TI - Hydration Structure and Dynamics of Inhibitor-Bound HIV-1 Protease. AB - Water is essential in many biological processes, and the hydration structure plays a critical role in facilitating protein folding, dynamics, and ligand binding. A variety of biophysical spectroscopic techniques have been used to probe the water solvating proteins, often complemented with molecular dynamics (MD) simulations to resolve the spatial and dynamic features of the hydration shell, but comparing relative water structure is challenging. In this study 1 MUs MD simulations were performed to identify and characterize hydration sites around HIV-1 protease bound to an inhibitor, darunavir (DRV). The water density, hydration site occupancy, extent and anisotropy of fluctuations, coordinated water molecules, and hydrogen bonds were characterized and compared to the properties of bulk water. The water density of the principal hydration shell was found to be higher than bulk, dependent on the topology and physiochemical identity of the biomolecular surface. The dynamics of water molecules occupying principal hydration sites was highly dependent on the number of water-water interactions and inversely correlated with hydrogen bonds to the protein inhibitor complex. While many waters were conserved following the symmetry of homodimeric HIV protease, the asymmetry induced by DRV resulted in asymmetric lower-occupancy hydration sites at the concave surface of the active site. Key interactions between water molecules and the protease, that stabilize the protein in the inhibited form, were altered in a drug resistant variant of the protease indicating that modulation of solvent-solute interactions might play a key role in conveying drug resistance. Our analysis provides insights into the interplay between an enzyme inhibitor complex and the hydration shell and has implications in elucidating water structure in a variety of biological processes and applications including ligand binding, inhibitor design, and resistance. PMID- 29570288 TI - A Molecular Dynamics-Quantum Mechanics Theoretical Study of DNA-Mediated Charge Transport in Hydrated Ionic Liquids. AB - Charge transport (CT) through biomolecules is of high significance in the research fields of biology, nanotechnology, and molecular devices. Inspired by our previous work that showed the binding of ionic liquid (IL) facilitated charge transport in duplex DNA, in silico simulation is a useful means to understand the microscopic mechanism of the facilitation phenomenon. Here molecular dynamics simulations (MD) of duplex DNA in water and hydrated ionic liquids were employed to explore the helical parameters. Principal component analysis was further applied to capture the subtle conformational changes of helical DNA upon different environmental impacts. Sequentially, CT rates were calculated by a QM/MM simulation of the flickering resonance model based upon MD trajectories. Herein, MD simulation illustrated that the binding of ionic liquids can restrain dynamic conformation and lower the on-site energy of the DNA base. Confined movement among the adjacent base pairs was highly related to the increase of electronic coupling among base pairs, which may lead DNA to a CT facilitated state. Sequentially combining MD and QM/MM analysis, the rational correlations among the binding modes, the conformational changes, and CT rates illustrated the facilitation effects from hydrated IL on DNA CT and supported a conformational gating mechanism. PMID- 29570289 TI - Systematic Evaluation of 2-Arylazocarboxylates and 2-Arylazocarboxamides as Mitsunobu Reagents. AB - 2-Arylazocarboxylate and 2-arylazocarboxamide derivatives can serve as replacements of typical Mitsunobu reagents such as diethyl azodicarboxylate. A systematic investigation of the reactivity and physical properties of those azo compounds has revealed that they have an excellent ability as Mitsunobu reagents. These reagents show similar or superior reactivity as compared to the known azo reagents and are applicable to the broad scope of substrates. p Ka and steric effects of substrates have been investigated, and the limitation of the Mitsunobu reaction can be overcome by choosing suitable reagents from the library of 2 arylazocarboxylate and 2-aryl azocarboxamide derivatives. Convenient recovery of azo reagents is available by one-pot iron-catalyzed aerobic oxidation, for example. SC-DSC analysis of representative 2-arylazocarboxylate and 2 arylazocarboxamide derivatives has shown high thermal stability, indicating that these azo reagents possess lower chemical hazard compared with typical azo reagents. PMID- 29570290 TI - Mechanochemistry-Based Synthesis of Highly Crystalline gamma-Zirconium Phosphate for Selective Ion Exchange. AB - Highly crystalline gamma-zirconium phosphate has been synthesized by a novel minimalistic approach and investigated as a selective ion exchanger for cesium, ammonium and potassium. In contrast to current solution-based preparations, the mechanochemistry-based synthesis provides easy access to gamma-zirconium phosphate with short synthesis times and low crystallization temperature. The addition of NaF as a mineralizer increases the crystallinity of gamma-zirconium phosphate, which forms micrometer-sized uniformly shaped rectangular platelets. The crystalline material has extremely high selectivity to cesium even in the presence of 1000- or 500-fold excess Na+ or Ca2+, respectively. The removal efficiency was >98% in the pH range of 2-5.5. As an ion exchanger for purification of dialysate, crystalline gamma-zirconium phosphate shows higher uptake of ammonium and potassium ions than the amorphous gel compound currently used in sorbent cartridges. This sustainable protocol opens up opportunities for many practical applications of gamma-zirconium phosphate. PMID- 29570291 TI - The Intricate Case of Tetramethyleneethane: A Full Configuration Interaction Quantum Monte Carlo Benchmark and Multireference Coupled Cluster Studies. AB - We have performed a full configuration interaction (FCI) quality benchmark calculation for the tetramethyleneethane molecule in the cc-pVTZ basis set employing a subset of complete active space second order perturbation theory, CASPT2(6,6), natural orbitals for the FCI quantum Monte Carlo calculation. The results are in an excellent agreement with the previous large scale diffusion Monte Carlo calculations by Pozun et al. and available experimental results. Our computations verified that there is a maximum on the potential energy surface (PES) of the ground singlet state (1A) 45 degrees torsional angle, and the corresponding vertical singlet-triplet energy gap is 0.01 eV. We have employed this benchmark for the assessment of the accuracy of Mukherjee's coupled clusters with up to triple excitations (MkCCSDT) and CCSD tailored by the density matrix renormalization group method (DMRG). Multireference MkCCSDT with CAS(2,2) model space, though giving good values for the singlet-triplet energy gap, is not able to properly describe the shape of the multireference singlet PES. Similarly, DMRG(24,25) is not able to correctly capture the shape of the singlet surface, due to the missing dynamic correlation. On the other hand, the DMRG-tailored CCSD method describes the shape of the ground singlet state with excellent accuracy but for the correct ordering requires computation of the zero-spin-projection component of the triplet state (3B1).

AB - Studies have linked the serine-threonine kinase MAP4K4 to the regulation of a number of biological processes and/or diseases, including diabetes, cancer, inflammation, and angiogenesis. With a majority of the members of our lead series (e.g., 1) suffering from time-dependent inhibition (TDI) of CYP3A4, we sought design avenues that would eliminate this risk. One such approach arose from the observation that carboxylic acid-based intermediates employed in our discovery efforts retained high MAP4K4 inhibitory potency and were devoid of the TDI risk. The medicinal chemistry effort that led to the discovery of this central nervous system-impaired inhibitor together with its preclinical safety profile is described. PMID- 29570293 TI - Is pi-Stacking Prone To Accelerate Singlet-Singlet Energy Transfers? AB - pi-Stacking is the most common structural feature that dictates the optical and electronic properties of chromophores in the solid state. Herein, a unidirectional singlet-singlet energy-transfer dyad has been designed to test the effect of pi-stacking of zinc(II) porphyrin, [Zn2], as a slipped dimer acceptor using a BODIPY unit, [bod], as the donor, bridged by the linker C6H4C=CC6H4. The rate of singlet energy transfer, kET(S1), at 298 K ( kET(S1) = 4.5 * 1010 s-1) extracted through the change in fluorescence lifetime, tauF, of [bod] in the presence (27.1 ps) and the absence of [Zn2] (4.61 ns) from Streak camera measurements, and the rise time of the acceptor signal in femtosecond transient absorption spectra (22.0 ps), is faster than most literature cases where no pi stacking effect exists (i.e., monoporphyrin units). At 77 K, the tauF of [bod] increases to 45.3 ps, indicating that kET(S1) decreases by 2-fold (2.2 * 1010 s 1), a value similar to most values reported in the literature, thus suggesting that the higher value at 298 K is thermally promoted at a higher temperature. PMID- 29570294 TI - Analyzing Fluxional Molecules Using DORI. AB - The Density Overlap Region Indicator (DORI) is a density-based scalar field that reveals covalent bonding patterns and noncovalent interactions in the same value range. This work goes beyond the traditional static quantum chemistry use of scalar fields and illustrates the suitability of DORI for analyzing geometrical and electronic signatures in highly fluxional molecular systems. Examples include a dithiocyclophane, which possesses multiple local minima with differing extents of pi-stacking interactions and a temperature dependent rotation of a molecular rotor, where the descriptor is employed to capture fingerprints of CH-pi and pi pi interactions. Finally, DORI serves to examine the fluctuating pi-conjugation pathway of a photochromic torsional switch (PTS). Attention is also placed on postprocessing the large amount of generated data and juxtaposing DORI with a data-driven low-dimensional representation of the structural landscape.

AB - We use dissipative particle dynamics (DPD) to study micelle formation in alkyl sulfate surfactants, with alkyl chain lengths ranging from 6 to 12 carbon atoms. We extend our recent DPD force field [ J. Chem. Phys. 2017 , 147 , 094503 ] to include a charged sulfate chemical group and aqueous sodium ions. With this model, we achieve good agreement with the experimentally reported critical micelle concentrations (CMCs) and can match the trend in mean aggregation numbers versus alkyl chain length. We determine the CMC by fitting a charged pseudophase model to the dependence of the free surfactant on the total surfactant concentration above the CMC and compare it with a direct operational definition of the CMC as the point at which half of the surfactant is classed as micellar and half as monomers and submicellar aggregates. We find that the latter provides the best agreement with experimental results. Finally, with the same model, we are able to observe the sphere-to-rod morphological transition for sodium dodecyl sulfate (SDS) micelles and determine that it corresponds to SDS concentrations in the region of 300-500 mM. PMID- 29570297 TI - Eliminating Spurious Zero-Efficiency FRET States in Diffusion-Based Single Molecule Confocal Microscopy. AB - Single-molecule Forster resonance energy transfer (smFRET) of freely diffusing biomolecules using confocal microscopy is a simple and powerful technique for measuring conformation and dynamics. However, a spurious zero-FRET population can significantly distort the measured histograms and lead to incorrect results, particularly in measurements of intrinsically low-FRET systems. Using a model system consisting of duplex DNAs, we show that there are two important contributions to the zero-FRET state: (1) formation of a dark triplet state of the acceptor dye and (2) the presence of donor-only strands due to incomplete hybridization between donor- and acceptor-labeled strands. The combined strategy of using Trolox as a triplet-state quencher and labeling the same DNA strand with donor and acceptor dyes effectively eliminates the zero-FRET population, even for constructs with intrinsically low FRET efficiencies. This strategy allows us to perform smFRET experiments using a simple confocal microscope with improved accuracy. PMID- 29570298 TI - Iron Oxide Nanoparticles-Based Vaccine Delivery for Cancer Treatment. AB - Modern therapeutic cancer vaccines need simple and effective formulations to enhance both humoral and cellular immune responses. Nanoparticles have obtained more and more attention in the development of vaccine delivery platforms. Moreover, nanoparticles-based vaccine delivery platform has high potential for improving the immunogenicity of vaccine. The Food and Drug Administration (FDA) has approved many types of iron oxide nanoparticles for clinical use, such as treating iron deficiency, contrast agents for magnetic resonance imaging (MRI) and drug delivery platforms. In this study, we explored a novel combined use of iron oxide nanoparticles (superparamagnetic Fe3O4 nanoparticles) as a vaccine delivery platform and immune potentiator, and investigated how this formulation affected cytokine expression in macrophages and dendritic cells (DCs) in vitro and tumor growth in vivo. Comparing with soluble OVA alone and iron oxide nanoparticles alone, we found significant differences in immune responses and tumor inhibition induced by OVA formulated with iron oxide nanoparticles. Our iron oxide nanoparticles greatly promoted the activation of immune cells and cytokine production, inducing potent humoral and cellular immune responses. These results suggest that this nanoparticle-based delivery system has strong potential to be utilized as a general platform for cancer vaccines. PMID- 29570299 TI - GE11-Directed Functional Polymersomal Doxorubicin as an Advanced Alternative to Clinical Liposomal Formulation for Ovarian Cancer Treatment. AB - Ovarian cancer as a recurrent disease is often refractory to treatment including pegylated liposomal doxorubicin hydrochloride (Lipo-Dox). Here, GE11 peptide modified reversibly cross-linked polymersomal doxorubicin (GE11-PS-Dox) was investigated as an advanced treatment for SKOV3 human ovarian tumors, which overexpress epidermal growth factor receptor (EGFR). The in vitro experiments using SKOV3 cancer cells demonstrated that GE11-PS-Dox induced obviously higher cellular uptake, Dox delivery to the nuclei, and antitumor activity than the nontargeted PS-Dox and Lipo-Dox controls. In vivo biodistribution experiments displayed 2.5-fold higher tumor accumulation for GE11-PS-Dox as compared to Lipo Dox. Notably, GE11-PS-Dox could effectively suppress the progression of SKOV3 tumors and cause little adverse effects at 12 mg of Dox equiv/kg, leading to a remarkably increased survival rate of 100% over 78 days. In contrast, continued tumor growth and body weight loss were discerned for Lipo-Dox treated mice at 6 mg of Dox equiv/kg.

AB - Rh(III)-catalyzed C-H activation of arenes and mild oxidative [4 + 2] annulative coupling with ketenes have been realized. The uniquely high reactivity of the C(3) of 2-phenylindoles was successfully utilized to facilitate the reductive elimination process, leading to efficient synthesis of cyclic products with a quaternary carbon stereocenter.

AB - Organic electrolytes are unique in that their constituent solvents may be of much lower dielectric strength than water. This is because the ions of organic electrolytes are often those that comprise room-temperature ionic liquids, which are surprisingly miscible with many different organic solvents of low dielectric strength. Strong ion correlation results from the relatively low dielectric screening of the solvent, resulting in properties that can substantially deviate from Debye-Huckel descriptions; in addition remains the fundamental question of why the ionic liquids and low dielectric solvents are even miscible in the first place. In this work, we study electrolyte mixtures composed of the room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM+][BF4-] mixed with four solvents of systematically varying dielectric strength, 1,2-dichloroethane, acetone, acetonitrile, and water. We show that miscibility with the lowest dielectric solvent, dichloroethane, is directly attributed to ion solvation enhancement mediated by both electronic and conformational polarization of the solvent molecules. A strong dielectric enhancement results from the ~70-80% increase in solvent dipole moments at high ion content, providing significantly better solvation than predicted by the bulk solvent dielectric strength. This implies a general mechanism for miscibility of ionic liquids with low dielectric solvents, through which ions effectly create their own solvation dipoles by polarizing the local environment. From a purely computational perspective, our results imply that explicitly polarizable force fields are essential for modeling many of the organic electrolytes that are used in electrochemical applications.

AB - Controlling the propagation and polarization vectors in linear and nonlinear optical spectroscopy enables us to probe the anisotropy of optical responses providing structural symmetry selective contrast in optical imaging. Here, we present a novel tilted antenna-tip approach to control the optical vector-field by breaking the axial symmetry of the nanoprobe in tip-enhanced near-field microscopy. This gives rise to a localized plasmonic antenna effect with significantly enhanced optical field vectors with control of both in-plane and out-of-plane components. We use the resulting vector-field specificity in the symmetry selective nonlinear optical response of second-harmonic generation (SHG) for a generalized approach to optical nanocrystallography and imaging. In tip enhanced SHG imaging of monolayer MoS2 films and single-crystalline ferroelectric YMnO3, we reveal nanocrystallographic details of domain boundaries and domain topology with enhanced sensitivity and nanoscale spatial resolution. The approach is applicable to any anisotropic linear and nonlinear optical response and enables the optical nanocrystallographic imaging of molecular or quantum materials.

AB - Multiplexed surface encoding is achieved by positioning two different sizes of gold nanocubes on gold surfaces with precisely defined locations for each particle via template-confined, DNA-mediated nanoparticle assembly. As a proof-of concept demonstration, cubes with 86 and 63 nm edge lengths are assembled into arrangements that physically and spectrally encrypt two sets of patterns in the same location. These patterns can be decrypted by mapping the absorption intensity of the substrate at lambda = 773 and 687 nm, respectively. This multiplexed encoding platform dramatically increases the sophistication and density of codes that can be written using colloidal nanoparticles, which may enable high-security, high-resolution encoding applications.

AB - The flexibility and quasi-one-dimensional nature of nanowires offer wide-ranging possibilities for novel heterostructure design and strain engineering. In this work, we realize arrays of extremely and controllably bent nanowires comprising lattice-mismatched and highly asymmetric core-shell heterostructures. Strain sharing across the nanowire heterostructures is sufficient to bend vertical nanowires over backward to contact either neighboring nanowires or the substrate itself, presenting new possibilities for designing nanowire networks and interconnects. Photoluminescence spectroscopy on bent-nanowire heterostructures reveals that spatially varying strain fields induce charge carrier drift toward the tensile-strained outside of the nanowires, and that the polarization response of absorbed and emitted light is controlled by the bending direction. This unconventional strain field is employed for light emission by placing an active region of quantum dots at the outer side of a bent nanowire to exploit the carrier drift and tensile strain. These results demonstrate how bending in nanoheterostructures opens up new degrees of freedom for strain and device engineering.

AB - We determined an empirical correlation that relates the amide I vibrational band frequencies of the glutamine (Q) side chain to the strength of hydrogen bonding, van der Waals, and Lewis acid-base interactions of its primary amide carbonyl. We used this correlation to determine the Q side chain carbonyl interaction enthalpy (Delta Hint) in monomeric and amyloid-like fibril conformations of D2Q10K2 (Q10). We independently verified these Delta Hint values through molecular dynamics simulations that showed excellent agreement with experiments. We found that side chain-side chain and side chain-peptide backbone interactions in fibrils and monomers are more enthalpically favorable than are Q side chain-water interactions. Q10 fibrils also showed a more favorable Delta Hint for side chain side chain interactions compared to backbone-backbone interactions. This work experimentally demonstrates that interamide side chain interactions are important in the formation and stabilization of polyQ fibrils.

AB - Active metasurfaces composed of electrically reconfigurable nanoscale subwavelength antenna arrays can enable real-time control of scattered light amplitude and phase. Achievement of widely tunable phase and amplitude in chip based active metasurfaces operating at or near 1550 nm wavelength has considerable potential for active beam steering, dynamic hologram rendition, and realization of flat optics with reconfigurable focal lengths. Previously, electrically tunable conducting oxide-based reflectarray metasurfaces have demonstrated dynamic phase control of reflected light with a maximum phase shift of 184 degrees ( Nano Lett. 2016 , 16 , 5319 ). Here, we introduce a dual-gated reflectarray metasurface architecture that enables much wider (>300 degrees ) phase tunability. We explore light-matter interactions with dual-gated metasurface elements that incorporate two independent voltage-controlled MOS field effect channels connected in series to form a single metasurface element that enables wider phase tunability. Using indium tin oxide (ITO) as the active metasurface material and a composite hafnia/alumina gate dielectric, we demonstrate a prototype dual-gated metasurface with a continuous phase shift from 0 to 303 degrees and a relative reflectance modulation of 89% under applied voltage bias of 6.5 V.

AB - Owing to their safety and low cost, aqueous rechargeable Zn-ion batteries (ARZIBs) are currently more feasible for grid-scale applications, as compared to their alkali counterparts such as lithium- and sodium-ion batteries (LIBs and SIBs), for both aqueous and nonaqueous systems. However, the materials used in ARZIBs have a poor rate capability and inadequate cycle lifespan, serving as a major handicap for long-term storage applications. Here, we report vanadium-based Na2V6O16.3H2O nanorods employed as a positive electrode for ARZIBs, which display superior electrochemical Zn storage properties. A reversible Zn2+-ion (de)intercalation reaction describing the storage mechanism is revealed using the in situ synchrotron X-ray diffraction technique. This cathode material delivers a very high rate capability and high capacity retention of more than 80% over 1000 cycles, at a current rate of 40C (1C = 361 mA g-1). The battery offers a specific energy of 90 W h kg-1 at a specific power of 15.8 KW kg-1, enlightening the material advantages for an eco-friendly atmosphere. PMID- 29570308 TI - Passivation of Plasmonic Colors on Bulk Silver by Atomic Layer Deposition of Aluminum Oxide. AB - We report the passivation of angle-independent plasmonic colors on bulk silver by atomic layer deposition (ALD) of thin films of aluminum oxide. The colors are rendered by silver nanoparticles produced by laser ablation and redeposition on silver. We then apply a two-step approach to aluminum oxide conformal film formation via ALD. In the first step, a low-density film is deposited at low temperature to preserve and pin the silver nanoparticles. In the second step, a second denser film is deposited at a higher temperature to provide tarnish protection. This approach successfully protects the silver and plasmonic colors against tarnishing, humidity, and temperature, as demonstrated by aggressive exposure trials. The processing time associated with deposition of the conformal passivation layers meets industry requirements, and the approach is compatible with mass manufacturing. PMID- 29570309 TI - Nanoscale Mapping and Control of Antenna-Coupling Strength for Bright Single Photon Sources. AB - Cavity quantum electrodynamics is the art of enhancing light-matter interaction of photon emitters in cavities with opportunities for sensing, quantum information, and energy capture technologies. To boost emitter-cavity interaction, that is, coupling strength g, ultrahigh quality cavities have been concocted yielding photon trapping times of microsecondsy to milliseconds. However, such high- Q cavities give poor photon output, hindering applications. To preserve high photon output, it is advantageous to strive for highly localized electric fields in radiatively lossy cavities. Nanophotonic antennas are ideal candidates combining low- Q factors with deeply localized mode volumes, allowing large g, provided the emitter is positioned exactly right inside the nanoscale mode volume. Here, with nanometer resolution, we map and tune the coupling strength between a dipole nanoantenna-cavity and a single molecule, obtaining a coupling rate of gmax ~ 200 GHz. Together with accelerated single photon output, this provides ideal conditions for fast and pure nonclassical single photon emission with brightness exceeding 109 photons/sec. Clearly, nanoantennas acting as "bad" cavities offer an optimal regime for strong coupling g to deliver bright on-demand and ultrafast single photon nanosources for quantum technologies. PMID- 29570310 TI - Fully Kinetic Simulation of 3D Kinetic Alfven Turbulence. AB - We present results from a three-dimensional particle-in-cell simulation of plasma turbulence, resembling the plasma conditions found at kinetic scales of the solar wind. The spectral properties of the turbulence in the subion range are consistent with theoretical expectations for kinetic Alfven waves. Furthermore, we calculate the local anisotropy, defined by the relation k_{?}(k_{?}), where k_{?} is a characteristic wave number along the local mean magnetic field at perpendicular scale l_{?}~1/k_{?}. The subion range anisotropy is scale dependent with k_{?}-z symmetric SOI can only explain the experimental results. Spin relaxation by the Elliot-Yafet mechanism and anomalous resistance increase with temperature close to the Dirac point indicates Kane-Mele SOI induced in graphene.

AB - We predict a strong enhancement of the critical temperature in a conventional Bardeen-Cooper-Schrieffer (BCS) superconductor in the presence of a bosonic condensate of exciton polaritons. The effect depends strongly on the ratio of the cutoff frequencies for phonon and exciton-polariton mediated BCS superconductivity, respectively. We also discuss a possible design of hybrid semiconductor-superconductor structures suitable for the experimental observation of such an effect. PMID- 29570327 TI - Charge Transfer Effects in Naturally Occurring van der Waals Heterostructures (PbSe)_{1.16}(TiSe_{2})_{m} (m=1, 2). AB - van der Waals heterostructures (VDWHs) exhibit rich properties and thus has potential for applications, and charge transfer between different layers in a heterostructure often dominates its properties and device performance. It is thus critical to reveal and understand the charge transfer effects in VDWHs, for which electronic structure measurements have proven to be effective. Using angle resolved photoemission spectroscopy, we studied the electronic structures of (PbSe)_{1.16}(TiSe_{2})_{m} (m=1, 2), which are naturally occurring VDWHs, and discovered several striking charge transfer effects. When the thickness of the TiSe_{2} layers is halved from m=2 to m=1, the amount of charge transferred increases unexpectedly by more than 250%. This is accompanied by a dramatic drop in the electron-phonon interaction strength far beyond the prediction by first principles calculations and, consequently, superconductivity only exists in the m=2 compound with strong electron-phonon interaction, albeit with lower carrier density. Furthermore, we found that the amount of charge transferred in both compounds is nearly halved when warmed from below 10 K to room temperature, due to the different thermal expansion coefficients of the constituent layers of these misfit compounds. These unprecedentedly large charge transfer effects might widely exist in VDWHs composed of metal-semiconductor contacts; thus, our results provide important insights for further understanding and applications of VDWHs.

AB - The Large Hadron Collider (LHC) is sensitive to new heavy gauge bosons that produce narrow peaks in the dilepton invariant mass spectrum up to about m_{Z^{'}}~5 TeV Z^{'}s that are too heavy to produce directly can reveal their presence through interference with standard model dilepton production. We show that the LHC can significantly extend the mass reach for such Z^{'}s by performing precision measurements of the shape of the dilepton invariant mass spectrum. The high-luminosity LHC can exclude, with 95% confidence, new gauge bosons as heavy as m_{Z^{'}}~10-20 TeV that couple with gauge coupling strength of g_{Z^{'}}~1-2. PMID- 29570329 TI - New Methods for Testing Lorentz Invariance with Atomic Systems. AB - We describe a broadly applicable experimental proposal to search for the violation of local Lorentz invariance (LLI) with atomic systems. The new scheme uses dynamic decoupling and can be implemented in current atomic clock experiments, with both single ions and arrays of neutral atoms. Moreover, the scheme can be performed on systems with no optical transitions, and therefore it is also applicable to highly charged ions which exhibit a particularly high sensitivity to Lorentz invariance violation. We show the results of an experiment measuring the expected signal of this proposal using a two-ion crystal of ^{88}Sr^{+} ions. We also carry out a systematic study of the sensitivity of highly charged ions to LLI to identify the best candidates for the LLI tests. PMID- 29570331 TI - Dynamics of Three-Body Correlations in Quenched Unitary Bose Gases. AB - We investigate dynamical three-body correlations in the Bose gas during the earliest stages of evolution after a quench to the unitary regime. The development of few-body correlations is theoretically observed by determining the two- and three-body contacts. We find that the growth of three-body correlations is gradual compared to two-body correlations. The three-body contact oscillates coherently, and we identify this as a signature of Efimov trimers. We show that the growth of three-body correlations depends nontrivially on parameters derived from both the density and Efimov physics. These results demonstrate the violation of scaling invariance of unitary bosonic systems via the appearance of log periodic modulation of three-body correlations. PMID- 29570330 TI - Symmorphic Intersecting Nodal Rings in Semiconducting Layers. AB - The unique properties of topological semimetals have strongly driven efforts to seek for new topological phases and related materials. Here, we identify a critical condition for the existence of intersecting nodal rings (INRs) in symmorphic crystals, and further classify all possible kinds of INRs which can be obtained in the layered semiconductors with Amm2 and Cmmm space group symmetries. Several honeycomb structures are suggested to be topological INR semimetals, including layered and "hidden" layered structures. Transitions between the three types of INRs, named as alpha, beta, and gamma type, can be driven by external strains in these structures. The resulting surface states and Landau-level structures, more complicated than those resulting from a simple nodal loop, are also discussed. PMID- 29570332 TI - Quantum Szilard Engine with Attractively Interacting Bosons. AB - We show that a quantum Szilard engine containing many bosons with attractive interactions enhances the conversion between information and work. Using an ab initio approach to the full quantum-mechanical many-body problem, we find that the average work output increases significantly for a larger number of bosons. The highest overshoot occurs at a finite temperature, demonstrating how thermal and quantum effects conspire to enhance the conversion between information and work. The predicted effects occur over a broad range of interaction strengths and temperatures. PMID- 29570333 TI - Ponderomotive Generation and Detection of Attosecond Free-Electron Pulse Trains. AB - Atomic motion dynamics during structural changes or chemical reactions have been visualized by pico- and femtosecond pulsed electron beams via ultrafast electron diffraction and microscopy. Imaging the even faster dynamics of electrons in atoms, molecules, and solids requires electron pulses with subfemtosecond durations. We demonstrate here the all-optical generation of trains of attosecond free-electron pulses. The concept is based on the periodic energy modulation of a pulsed electron beam via an inelastic interaction, with the ponderomotive potential of an optical traveling wave generated by two femtosecond laser pulses at different frequencies in vacuum. The subsequent dispersive propagation leads to a compression of the electrons and the formation of ultrashort pulses. The longitudinal phase space evolution of the electrons after compression is mapped by a second phase-locked interaction. The comparison of measured and calculated spectrograms reveals the attosecond temporal structure of the compressed electron pulse trains with individual pulse durations of less than 300 as. This technique can be utilized for tailoring and initial characterization of suboptical-cycle free-electron pulses at high repetition rates for stroboscopic time-resolved experiments with subfemtosecond time resolution.

AB - We implement imaging spectroscopy of the optical clock transition of lattice trapped degenerate fermionic Sr in the Mott-insulating regime, combining micron spatial resolution with submillihertz spectral precision. We use these tools to demonstrate atomic coherence for up to 15 s on the clock transition and reach a record frequency precision of 2.5*10^{-19}. We perform the most rapid evaluation of trapping light shifts and record a 150 mHz linewidth, the narrowest Rabi line shape observed on a coherent optical transition. The important emerging capability of combining high-resolution imaging and spectroscopy will improve the clock precision, and provide a path towards measuring many-body interactions and testing fundamental physics.

AB - The energy-energy correlation (EEC) between two detectors in e^{+}e^{-} annihilation was computed analytically at leading order in QCD almost 40 years ago, and numerically at next-to-leading order (NLO) starting in the 1980s. We present the first analytical result for the EEC at NLO, which is remarkably simple, and facilitates analytical study of the perturbative structure of the EEC. We provide the expansion of the EEC in the collinear and back-to-back regions through next-to-leading power, information which should aid resummation in these regions. PMID- 29570335 TI - Spatial Distortion of Vibration Modes via Magnetic Correlation of Impurities. AB - Long wavelength vibrational modes in the ferromagnetic semiconductor Ga_{0.91}Mn_{0.09}As are investigated using time resolved x-ray diffraction. At room temperature, we measure oscillations in the x-ray diffraction intensity corresponding to coherent vibrational modes with well-defined wavelengths. When the correlation of magnetic impurities sets in, we observe the transition of the lattice into a disordered state that does not support coherent modes at large wavelengths. Our measurements point toward a magnetically induced broadening of long wavelength vibrational modes in momentum space and their quasilocalization in the real space. More specifically, long wavelength vibrational modes cannot be assigned to a single wavelength but rather should be represented as a superposition of plane waves with different wavelengths. Our findings have strong implications for the phonon-related processes, especially carrier-phonon and phonon-phonon scattering, which govern the electrical conductivity and thermal management of semiconductor-based devices. PMID- 29570338 TI - 1/2(e^{2}/h) Conductance Plateau without 1D Chiral Majorana Fermions. AB - We address the question about the origin of the 1/2(e^{2}/h) conductance plateau observed in a recent experiment on an integer quantum Hall (IQH) film covered by a superconducting (SC) film. Since one-dimensional (1D) chiral Majorana fermions on the edge of the above device can give rise to the half quantized plateau, such a plateau is regarded as conclusive evidence for the chiral Majorana fermions. However, in this Letter we give another mechanism for the 1/2(e^{2}/h) conductance plateau. We find the 1/2(e^{2}/h) conductance plateau to be a general feature of a good electric contact between the IQH film and the SC film, and cannot distinguish the existence or the nonexistence of 1D chiral Majorana fermions. We also find that the contact conductance between a superconductor and an IQH edge channel has a non-Ohmic form sigma_{SC-Hall}?V^{2} in the k_{B}T?eV limit, if the SC and IQH bulks are fully gapped.

AB - The first direct experimental measurements of the scattering of a millimeter-wave beam by plasma blobs in a simple magnetized torus are reported. The wavelength of the beam is comparable to the characteristic size of the blob. In situ Langmuir probe measurements show that fluctuations of the electron density induce correlated fluctuations of the transmitted power. A first-principles full-wave model, using conditionally sampled 2D electron density profiles, predicts fluctuations of the millimeter-wave power that are in agreement with experiments.

The experimental setups have been found by a computer algorithm, and can be intuitively understood in a geometric way. Together with the ability to sort angular-momentum modes, we now have access to the complete two-dimensional transverse plane of light. The device can readily be used in multiplexing classical information. On a quantum level, it is an analog of the Stern-Gerlach experiment-significant for the discussion of fundamental concepts in quantum physics. As such, it can be applied in high-dimensional and multiphotonic quantum experiments. PMID- 29570340 TI - Quartic Anharmonicity of Rattlers and Its Effect on Lattice Thermal Conductivity of Clathrates from First Principles. AB - We investigate the role of the quartic anharmonicity in the lattice dynamics and thermal transport of the type-I clathrate Ba_{8}Ga_{16}Ge_{30} based on ab initio self-consistent phonon calculations. We show that the strong quartic anharmonicity of rattling guest atoms causes the hardening of vibrational frequencies of low-lying optical modes and thereby affects calculated lattice thermal conductivities kappa_{L} significantly, resulting in an improved agreement with experimental results including the deviation from kappa_{L}?T^{-1} at high temperature. Moreover, our static simulations with various different cell volumes shows a transition from crystal-like to glasslike kappa_{L} around 20 K. Our analyses suggest that the resonance dip of kappa_{L} observed in clathrates with large guest free spaces is attributed mainly to the strong three-phonon scattering of acoustic modes along with the presence of higher-frequency dispersive optical modes. PMID- 29570341 TI - Setting Boundaries with Memory: Generation of Topological Boundary States in Floquet-Induced Synthetic Crystals. AB - When a d-dimensional quantum system is subjected to a periodic drive, it may be treated as a (d+1)-dimensional system, where the extra dimension is a synthetic one. This approach, however, affords only a limited level of control of the effective potential along the synthetic direction. In this work, we introduce a new mean for controlling the Floquet synthetic dimension. We show that arbitrary potentials, as well as edges in the synthetic dimension, could be introduced using a memory component in the system's dynamics. We demonstrate this principle by exploring topological edge states propagating normal to synthetic dimensions. Such systems may act as an optical isolator which allows the transmission of light in a directional way. Also, we suggest an experimental realization of the memory effect in spins coupled to nanofabricated Weyl semimetal surface states.

AB - We use 413 weeks of publicly available Fermi Pass 8 gamma-ray data combined with recently developed galaxy group catalogs to search for evidence of dark matter annihilation in extragalactic halos. In our study, we use luminosity-based mass estimates and mass-to-concentration relations to infer the J factors and associated uncertainties for hundreds of galaxy groups within a redshift range z?0.03. We employ a conservative substructure boost factor model, which only enhances the sensitivity by an O(1) factor. No significant evidence for dark matter annihilation is found, and we exclude thermal relic cross sections for dark matter masses below ~30 GeV to 95% confidence in the bb[over -] annihilation channel. These bounds are comparable to those from Milky Way dwarf spheroidal satellite galaxies. The results of our analysis increase the tension but do not rule out the dark matter interpretation of the Galactic Center excess. We provide a catalog of the galaxy groups used in this study and their inferred properties, which can be broadly applied to searches for extragalactic dark matter. PMID- 29570343 TI - In Silico Measurement of Elastic Moduli of Nematic Liquid Crystals. AB - Experiments on confined droplets of the nematic liquid crystal 5CB have questioned long-established bounds imposed on the elastic free energy of nematic systems. This elasticity, which derives from molecular alignment within nematic systems, is quantified through a set of moduli which can be difficult to measure experimentally and, in some cases, can only be probed indirectly. This is particularly true of the surfacelike saddle-splay elastic term, for which the available experimental data indicate values on the cusp of stability, often with large uncertainties. Here, we demonstrate that all nematic elastic moduli, including the saddle-splay elastic constant k_{24}, may be calculated directly from atomistic molecular simulations. Importantly, results obtained through in silico measurements of the 5CB elastic properties demonstrate unambiguously that saddle-splay elasticity alone is unable to describe the observed confined morphologies.

AB - We exploit an intense terahertz magnetic near field combined with femtosecond laser excitation to break the symmetry of photoinduced spin reorientation paths in ErFeO_{3}. We succeed in aligning macroscopic magnetization reaching up to 80% of total magnetization in the sample to selectable orientations by adjusting the time delay between terahertz and optical pump pulses. The spin dynamics are well reproduced by equations of motion, including time-dependent magnetic potential. We show that the direction of the generated magnetization is determined by the transient direction of spin tilting and the magnetic field at the moment of photoexcitation. PMID- 29570345 TI - Entanglement between a Photonic Time-Bin Qubit and a Collective Atomic Spin Excitation. AB - Entanglement between light and matter combines the advantage of long distance transmission of photonic qubits with the storage and processing capabilities of atomic qubits. To distribute photonic states efficiently over long distances several schemes to encode qubits have been investigated-time-bin encoding being particularly promising due to its robustness against decoherence in optical fibers. Here, we demonstrate the generation of entanglement between a photonic time-bin qubit and a single collective atomic spin excitation (spin wave) in a cold atomic ensemble, followed by the mapping of the atomic qubit onto another photonic qubit. A magnetic field that induces a periodic dephasing and rephasing of the atomic excitation ensures the temporal distinguishability of the two time bins and plays a central role in the entanglement generation. To analyze the generated quantum state, we use largely imbalanced Mach-Zehnder interferometers to perform projective measurements in different qubit bases and verify the entanglement by violating a Clauser-Horne-Shimony-Holt Bell inequality.

AB - We investigated the ultrafast terahertz (THz) nonlinearity in a monolayer graphene under the strong magnetic field using THz pump-THz probe spectroscopy. An ultrafast suppression of the Faraday rotation associated with inter-Landau level (LL) transitions is observed, reflecting the Dirac electron character of nonequidistant LLs with large transition dipole moments. A drastic modulation of electron distribution in LLs is induced by far off-resonant THz pulse excitation in the transparent region. Numerical simulation based on the density matrix formalism without rotating-wave approximation reproduces the experimental results. Our results indicate that the strong light-matter coupling regime is realized in graphene, with the Rabi frequency exceeding the carrier wave frequency and even the relevant energy scale of the inter-LL transition.

AB - MicroRNAs (miRNAs) are known as the master regulators of gene expression, and for the last two decades our knowledge of their functional reach keeps expanding. Recent studies have shown that a miRNA's role in regulation extends to extracellular and intracellular organelles. Several studies have shown a role for miRNA in regulating the mitochondrial genome in normal and disease conditions. Mitochondrial dysfunction occurs in many human pathologies, such as cardiovascular disease, diabetes, cancer, and neurological diseases. These studies have shed some light on regulation of the mitochondrial genome as well as helped to explain the role of miRNA in altering mitochondrial function and the ensuing effects on cells. Although the field has grown in recent years, many questions still remain. For example, little is known about how nuclear-encoded miRNAs translocate to the mitochondrial matrix. Knowledge of the mechanisms of miRNA transport into the mitochondrial matrix is likely to provide important insights into our understanding of disease pathophysiology and could represent new targets for therapeutic intervention. For this review, our focus will be on the role of a subset of miRNAs, known as MitomiR, in mitochondrial function. We also discuss the potential mechanisms used by these nuclear-encoded miRNAs for import into the mitochondrial compartment.

Structural studies of the ribosome and of its complexes with factors and inhibitors have provided invaluable information on the mechanism of protein synthesis. Ribosome inhibitors are among the most successful antimicrobial drugs and constitute more than half of all medicines used to treat infections. However, bacterial infections are becoming increasingly difficult to treat because the microbes have developed resistance to the most effective antibiotics, creating a major public health care threat. This has spurred a renewed interest in structure-function studies of protein synthesis inhibitors, and in few cases, compounds have been developed into potent therapeutic agents against drug-resistant pathogens. In this review, we describe the modes of action of many ribosome-targeting antibiotics, highlight the major resistance mechanisms developed by pathogenic bacteria, and discuss recent advances in structure-assisted design of new molecules.

AB - The ability of bacterial cells to adjust their gene expression program in response to environmental perturbation is often critical for their survival. Recent experimental advances allowing us to quantitatively record gene expression dynamics in single cells and in populations coupled with mathematical modeling enable mechanistic understanding on how these responses are shaped by the underlying regulatory networks. Here, we review how the combination of local and global factors affect dynamical responses of gene regulatory networks. Our goal is to discuss the general principles that allow extrapolation from a few model bacteria to less understood microbes. We emphasize that, in addition to well studied effects of network architecture, network dynamics are shaped by global pleiotropic effects and cell physiology.

We included all patients undergoing hip arthroscopy who agreed to participate and who completed 4 patient-reported outcome (PRO) instruments at a minimum 2-year follow-up: the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sport-Specific Subscale. The NAHS was selected as our primary outcome instrument. All patients with any previous hip conditions were excluded. We analyzed 34 preoperative and intraoperative variables using bivariate and multivariate analyses compared with NAHS. RESULTS: The cohort consisted of 1038 patients with a mean follow-up of 30.1 months (range, 24.0-61.2 months). Mean age was 36.4 years (range, 13.2-76.4 years). All postoperative PRO scores showed significant improvement ( P < .001) at 2 years compared with preoperative scores. Bivariate analysis identified 15 variables (7 categorical and 8 continuous) and multivariate analysis identified 10 variables that were predictive of 2-year postoperative NAHS. Preoperative NAHS, preoperative HOS-ADL, preoperative mHHS, age, duration of symptoms, body mass index (BMI), and revision hip arthroscopy were identified as predictive factors in both bivariate and multivariate analyses. The predictive value of preoperative NAHS was accentuated for patients with higher BMI. CONCLUSION: This study reports favorable clinical outcomes in the largest cohort of hip arthroscopies with a minimum 2-year follow-up in the literature to date. Factors identified as predictive in both bivariate and multivariate analyses included preoperative NAHS, HOS-ADL, and mHHS; age; duration of symptoms; BMI; and revision hip arthroscopy. These predictive factors may be useful to the clinician in determining prognosis and operative indications for hip arthroscopy. PMID- 29570355 TI - Findings from an Assessment and Inventory of a Regional, Decentralized Stockpile. AB - Stockpiles can aid with healthcare surge that occurs after a disaster, and experts recommend that these caches be assessed at least annually to ensure supply integrity. The purpose of this study was to assess a regional stockpile to determine its viability and readiness. An assessment was performed in the summer and fall of 2016 on a regionally funded stockpile that was decentralized through a regional network of 15 local hospitals. Each supply was assessed to determine whether the correct amount was present, if it was in a safe and usable condition (ie, deployable), and whether it had expired. Stockpiled materials were categorized by the type of supply or equipment for analysis. The percent of deployable materials was calculated for each item, each category of supplies, and for the entire cache. Almost all sites (93.3%, n = 14) reported that they inventory their cache at least once a year. On average, 60.1% of each site's cache materials were present and deployable (range: 22.1%-87.5%). The best maintained supplies included personal protective equipment (79.4% deployable) and general medical supplies (73.5% deployable). Decontamination equipment and pediatric supplies had the lowest percentages of deployability (29.0% and 37.7%, respectively). Although almost all sites claimed to assess the stockpile annually, results from this study indicate that almost half of the supplies are either missing or in an unusable condition. This not only represents wasted resources, but it could also hinder disaster response, leading to increased morbidity and mortality. Facilities may need to invest in infrastructure to maintain stockpiled materials after purchase to ensure viability. PMID- 29570356 TI - Crystal Engineering for Catalysis. AB - Crystal engineering relies upon the ability to predictively control intermolecular interactions during the assembly of crystalline materials in a manner that leads to a desired (and predetermined) set of properties. Economics, scalability, and ease of design must be leveraged with techniques that manipulate the thermodynamics and kinetics of crystal nucleation and growth. It is often challenging to exact simultaneous control over multiple physicochemical properties, such as crystal size, habit, chirality, polymorph, and composition. Engineered materials often rely upon postsynthesis (top-down) processes to introduce properties that would otherwise be challenging to attain through direct (bottom-up) approaches. We discuss the application of crystal engineering to heterogeneous catalysts with a focus on four general themes: ( a) tailored nanocrystal size, ( b) controlled environments surrounding active sites, ( c) tuned morphology with well-defined facets, and ( d) hierarchical materials with disparate pore size and active site distributions. We focus on nonporous materials, including metals and metal oxides, and two classes of porous materials: zeolites and metal organic frameworks. We review novel synthesis methods involving synergistic experimental and computational design approaches, the challenges facing catalyst development, and opportunities for future advancement in crystal engineering. PMID- 29570357 TI - Single- to Few-Layered, Graphene-Based Separation Membranes. AB - Two-dimensional, graphene-based materials have attracted great attention as a new membrane building block, primarily owing to their potential to make the thinnest possible membranes and thus provide the highest permeance for effective sieving, assuming comparable porosity to conventional membranes and uniform molecular sized pores. However, a great challenge exists to fabricate large-area, single layered graphene or graphene oxide (GO) membranes that have negligible undesired transport pathways, such as grain boundaries, tears, and cracks. Therefore, model systems, such as a single flake or nanochannels between graphene or GO flakes, have been studied via both simulations and experiments to explore the transport mechanisms and separation potential of graphene-based membranes. This article critically reviews literature related to single- to few-layered graphene and GO membranes, from material synthesis and characteristics, fundamental membrane structures, and transport mechanisms to potential separation applications. Knowledge gaps between science and engineering in this new field and future opportunities for practical separation applications are also discussed. PMID- 29570358 TI - Long Noncoding RNA LINC00958 Accelerates Gliomagenesis Through Regulating miR 203/CDK2. AB - Increasing evidence has indicated that long noncoding RNAs (lncRNAs) play crucial roles in various biological processes, including glioma. However, the underlying mechanism of lncRNAs in gliomagenesis is still ambiguous. In this study, we aim to investigate the role of long intergenic noncoding RNA 00958 (LINC00958) in the tumorigenesis of glioma. Results revealed that LINC00958 was significantly upregulated in glioma tissues and cell lines compared with that of adjacent normal brain tissues and normal human astrocytes. Moreover, the ectopic overexpression of LINC00958 was correlated with poor prognosis of glioma patients. Loss-of-function experiments indicated that LINC00958 knockdown suppressed glioma cell proliferation, invasion, and induced cycle arrest at G0/G1 phase in vitro, and inhibited tumor growth in vivo. Bioinformatics programs and luciferase reporter assay revealed that miR-203 shared complementary binding sites with both 3'-untranslated region of LINC00958 and CDK2. In summary, our study concludes that LINC00958 acts as an oncogenic gene in the gliomagenesis through miR-203-CDK2 regulation, providing a novel insight into glioma tumorigenesis. PMID- 29570359 TI - Progestogens and venous thromboembolism in menopausal women: an updated oral versus transdermal estrogen meta-analysis. AB - Postmenopausal hormone therapy (HT) is a modifiable risk factor for venous thromboembolism (VTE). While the route of estrogen administration is now well recognized as an important determinant of VTE risk, there is also increasing evidence that progestogens may modulate the estrogen-related VTE risk. This review updates previous meta-analyses of VTE risk in HT users, focusing on the route of estrogen administration, hormonal regimen and progestogen type. Among women using estrogen-only preparations, oral but not transdermal preparations increased VTE risk (relative risk (RR) 1.48, 95% confidence interval (CI) 1.39 1.58; RR 0.97, 95% CI 0.87-1.09, respectively). In women using opposed estrogen, results were highly heterogeneous due to important differences between the molecules of progestogen. In transdermal estrogen users, there was no change in VTE risk in women using micronized progesterone (RR 0.93, 95% CI 0.65-1.33), whereas norpregnane derivatives were associated with increased VTE risk (RR 2.42, 95% CI 1.84-3.18). Among women using opposed oral estrogen, there was higher VTE risk in women using medroxyprogesterone acetate (RR 2.77, 95% CI 2.33-3.30) than in those using other progestins. These clinical findings, together with consistent biological data, emphasize the safety advantage of transdermal estrogen combined with progesterone and support the current evidence-based recommendations on HT, especially in women at high VTE risk. PMID- 29570360 TI - Interfacing Cells with Vertical Nanoscale Devices: Applications and Characterization. AB - Measurements of the intracellular state of mammalian cells often require probes or molecules to breach the tightly regulated cell membrane. Mammalian cells have been shown to grow well on vertical nanoscale structures in vitro, going out of their way to reach and tightly wrap the structures. A great deal of research has taken advantage of this interaction to bring probes close to the interface or deliver molecules with increased efficiency or ease. In turn, techniques have been developed to characterize this interface. Here, we endeavor to survey this research with an emphasis on the interface as driven by cellular mechanisms. PMID- 29570361 TI - Optimizing the flavanone core toward new selective nitrogen-containing modulators of ABC transporters. AB - AIM: Naringenin (1), isolated in large amount from the aerial parts of Euphorbia pedroi, was chemically derivatized to yield 18 imine derivatives (2-19) and three alkylated derivatives through a Mannich-type reaction (20-22) that were tested as multidrug resistance (MDR) reversers in cancer cells. Results/methodology: While hydrazone (2-4) and azine (5-13) derivatives showed an improvement in their MDR reversal activities against the breast cancer resistance protein, carbohydrazides 14-19 revealed an enhancement in MDR reversal activity toward the multidrug resistance protein 1. CONCLUSION: The observed activities, together with pharmacophoric analysis and molecular docking studies, identified the spatial orientation of the substituents as a key structural feature toward a possible mechanism by which naringenin derivatives may reverse MDR in cancer. PMID- 29570362 TI - Verbal test of practical judgment (VPJ): a new test of judgment that predicts functional skills for older adults. AB - OBJECTIVES: The clinical assessment of older adults' judgment is important for mitigating safety risks that often precipitate loss of independence. Our national survey of geriatric healthcare providers (N = 496; M years of experience = 17.11 +/- 10.60) indicated that formal judgment tests are underutilized in clinical practice. We developed the Verbal Test of Practical Judgment (VPJ) as a new test of judgment for older adults intended to identify difficulty performing instrumental activities of daily living (IADL). METHOD: In two prospective studies, participants were long-term care facility residents (age >= 50) in Maryland, USA (Study 1, N = 51; Study 2, N = 110) referred to licensed psychologists for neuro-cognitive and mood evaluation by facility attending physicians. Psychometric analyses were performed to examine the construct validity of the VPJ. RESULTS: The VPJ evidenced adequate reliability and strong construct validity across both studies. Receiver operating characteristic analysis yielded an optimal VPJ cut score for identifying impaired judgment. The VPJ significantly predicted IADL performance beyond clinician and participant ratings. CONCLUSION: The VPJ appears to be a valid tool for assessing judgment among older adults with suspected cognitive impairment. VPJ score inferences can inform clinicians on the odds of requiring assistance for specific IADLs. PMID- 29570363 TI - Pharmacist Views on Alternative Methods for Antiviral Distribution and Dispensing During an Influenza Pandemic. AB - Antiviral drugs are likely to be a frontline countermeasure needed to minimize disease impact during an influenza pandemic. As part of pandemic influenza preparedness efforts, the Centers for Disease Control and Prevention, in coordination with state health departments, has plans in place to distribute and dispense antiviral drugs from public stockpiles. These plans are currently under review and include evaluation of the benefits of commercial distribution and dispensing through community pharmacies. To ensure this alternative distribution and dispensing system is viable, it is critical to assess pharmacist acceptability and to understand the pharmacist perspective on dispensing these antivirals during a response. In this study, we examine community pharmacist reactions to the proposed alternative antiviral distribution and dispensing system using a nationally representative survey of pharmacists. Overall, pharmacists were highly receptive to this alternative system and voiced a willingness to participate personally, and most thought their own pharmacy would participate in such an effort. This was true across pharmacists with different personal and professional backgrounds, as well as those in different pharmacy settings. However, sizable shares of pharmacists said they were worried about facing shortages of the antivirals, the risk of exposure to disease for themselves and their families, managing their usual patients who need their prescriptions filled for medications other than antivirals, keeping order in the pharmacy, and potential liability concerns. These findings should be interpreted as an indication of acceptability of the concept, encouragement for the next steps in alternative distribution and dispensing system design, and a guide to potential barriers that may need to be addressed proactively. PMID- 29570364 TI - Protein Quality Control in the Endoplasmic Reticulum of Plants. AB - The endoplasmic reticulum (ER) is the site of maturation for roughly one-third of all cellular proteins. ER-resident molecular chaperones and folding catalysts promote folding and assembly in a diverse set of newly synthesized proteins. Because these processes are error-prone, all eukaryotic cells have a quality control system in place that constantly monitors the proteins and decides their fate. Proteins with potentially harmful nonnative conformations are subjected to assisted folding or degraded. Persistent folding-defective proteins are distinguished from folding intermediates and targeted for degradation by a specific process involving clearance from the ER. Although the basic principles of these processes appear conserved from yeast to animals and plants, there are distinct differences in the ER-associated degradation of misfolded glycoproteins. The general importance of ER quality-control events is underscored by their involvement in the biogenesis of diverse cell surface receptors and their crucial maintenance of protein homeostasis under diverse stress conditions. PMID- 29570365 TI - Nitrate Transport, Signaling, and Use Efficiency. AB - Nitrogen accounts for approximately 60% of the fertilizer consumed each year; thus, it represents one of the major input costs for most nonlegume crops. Nitrate is one of the two major forms of nitrogen that plants acquire from the soil. Mechanistic insights into nitrate transport and signaling have enabled new strategies for enhancing nitrogen utilization efficiency, for lowering input costs for farming, and, more importantly, for alleviating environmental impacts (e.g., eutrophication and production of the greenhouse gas N2O). Over the past decade, significant progress has been made in understanding how nitrate is acquired from the surroundings, how it is efficiently distributed into different plant tissues in response to environmental changes, how nitrate signaling is perceived and transmitted, and how shoot and root nitrogen status is communicated. Several key components of these processes have proven to be novel tools for enhancing nitrate- and nitrogen-use efficiency. In this review, we focus on the roles of NRT1 and NRT2 in nitrate uptake and nitrate allocation among different tissues; we describe the functions of the transceptor NRT1.1, transcription factors, and small signaling peptides in nitrate signaling and tissue communication; and we compile the new strategies for improving nitrogen use efficiency. PMID- 29570314 TI - D-Meson Azimuthal Anisotropy in Midcentral Pb-Pb Collisions at sqrt[s]_{NN}=5.02 TeV. AB - The azimuthal anisotropy coefficient v_{2} of prompt D^{0}, D^{+}, D^{*+}, and D_{s}^{+} mesons was measured in midcentral (30%-50% centrality class) Pb-Pb collisions at a center-of-mass energy per nucleon pair sqrt[s_{NN}]=5.02 TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at midrapidity, |y|<0.8, in the transverse momentum interval 1= 85 HU was detected in 30 (88.2%) pheochromocytomas (p < 0.001) and in seven (16.3%) adenomas. Venous phase enhancement of < 85 HU was detected in four (11.8%) pheochromocytomas and in 36 (83.7%) adenomas. Of the pheochromocytomas imaged with a triphasic protocol (n = 15), 66.7% (n = 10) met both absolute and relative percentage washout criteria for the diagnosis of a lipid-poor adenoma (p > 0.1). CONCLUSION: A significant subset of pheochromocytomas mimics adenomas on absolute or relative percentage washout calculations. However, nodules with venous phase enhancement of 85 HU or more are much more likely to be pheochromocytomas than adenomas, regardless of whether the lesion shows absolute or relative percentage washout compatible with a lipid-poor adenoma. The typical values of absolute and relative percentage washout of adrenal adenoma should be interpreted along with the venous phase enhancement value to avoid potential misdiagnoses. PMID- 29570378 TI - JOURNAL CLUB: Preparative Fasting for Contrast-Enhanced CT in a Cancer Center: A New Approach. AB - OBJECTIVE: Most diagnostic imaging centers ask patients to fast for 4-6 hours before contrast-enhanced CT. Previous studies have shown that prolonged fasting can be harmful. In addition, manufacturers of contrast agents claim that there is no special preparation needed before examination. The aim of this study was to evaluate the effects of preparative fasting on contrast-enhanced CT at a cancer center. SUBJECTS AND METHODS: Outpatients (n = 3206) were prospectively evaluated and randomly assigned to two groups: the 1619 patients in group 1 fasted for at least 4 hours before the examination, whereas the 1587 patients in group 2 received a light meal. Adverse symptoms observed before and after contrast agent administration were compared between groups. RESULTS: Adverse symptoms occurring after IV contrast agent administration were reported by 45 patients (1.5%) in group 1 and 30 patients (0.9%) in group 2. The most common symptoms were nausea (n = 32), weakness (n = 12), and vomiting (n = 5). The frequency of symptoms did not differ statistically significantly between groups (p > 0.05). CONCLUSION: In this sample of patients with cancer undergoing contrast-enhanced CT, very few adverse symptoms were reported regardless of preparative fasting. These results support the idea that preparation for contrast-enhanced CT can be simplified, decreasing the discomfort and inconvenience experienced by patients. PMID- 29570379 TI - 2013-2018: New and Ongoing Challenges. PMID- 29570380 TI - Neonatal Macroglossia: Demographics, Cost of Care, and Associated Comorbidities. AB - OBJECTIVES: To examine the birth prevalence of congenital macroglossia and identify demographic variables and comorbidities that may influence length of stay and cost of care. STUDY DESIGN: Retrospective cross-sectional study using the Kids' Inpatient Database 2003, 2006, 2009, and 2012. METHODS: Demographics were analyzed. Linear regression modeling and multivariate analyses were performed. RESULTS: The birth prevalence of congenital macroglossia was 4.63/100 000 births. Patients were classified as isolated (n = 349, 48.1%) or syndromic (n = 377, 51.9%). A higher incidence of isolated macroglossia was seen in females (odds ratio, OR [95% confidence interval, 95% CI]: 1.93 [1.45-2.56] and African Americans (2.02 [1.41-2.88]). Length of stay was higher for syndromic patients than for nonsyndromic patients (22.6 days [18.6-26.6] vs 7.93 days [5.95-9.90], as were inpatient costs ($3619USD [$27 628-$44 754] vs $10 168USD [$6272-$14 064]. After accounting for gender, race, location, and socioeconomic status, the presence of macroglossia alone increased length of stay by 4.07 days (0.42-7.72 days) in nonsyndromic patients and 12.02 days (3.63-20.4 days) in syndromic patients. The cost of care increased by $6207USD ($576-$11 838) among nonsyndromic newborns and $17 205USD ($374-34 035) among syndromic patients. CONCLUSION: The birth prevalence of congenital isolated macroglossia appears to vary by sex and race. Prolonged length of stay and increased costs are associated with both isolated macroglossia and syndromic macroglossia, even after controlling for other syndromic comorbidities. PMID- 29570381 TI - Sociodemographic Predictors of Missed Appointments Among Patients With Cleft Lip and Palate. AB - OBJECTIVE: To identify disparities in compliance of and care for patients with cleft lip and/or palate (CL/P) by determining the impact of sociodemographic variables on the rate of missed appointments and Child Protective Services (CPS) involvement. DESIGN: A retrospective, noninterventional quality assessment and quality improvement study were designed. SETTING: This institutional study was performed at the University of Michigan in Ann Arbor, Michigan. PATIENTS: All patients born between January 1, 2011, and December 31, 2014, who underwent surgical CL/P repair, excluding those with fewer than 5 appointments (n = 178). MAIN OUTCOME MEASURE: The rate of missed appointments, calculated as the total number of no-show appointments divided by the total number of scheduled appointments. All appointments from CL/P diagnosis to data collection were considered, including those outside of plastic surgery. RESULTS: The average patient was 4.5 years of age and had 49 total scheduled appointments. The overall rate of missed appointments was 9.6%, with 66.8% of patients missing at least 1 scheduled visit. Patients who were black ( P = .04), not affiliated with a religion ( P = .01), Medicaid users ( P = .01), from an unstable social background ( P = .01), or received need-based financial assistance ( P = .00) were significantly more likely to miss appointments. Child Protective Services was involved with 3.9% of patients. CONCLUSIONS: Disparities exist in attendance rates among patients with CL/P, and at-risk patient populations have been identified. The allocation of cleft care resources must be efficiently planned in order to enhance the quality of care for at-risk individuals. PMID- 29570382 TI - #CleftProud: A Content Analysis and Online Survey of 2 Cleft Lip and Palate Facebook Groups. AB - BACKGROUND: More than 2 billion people worldwide now use social networking sites, with an increasing number of users accessing these sites to obtain health information and engage in emotional support. Yet, investigation of social networking sites in the context of cleft lip and/or palate (CL/P) has been scarce. METHODS: Real-time data posted during 2 weeks in April 2017 were collected from 2 existing private Facebook groups (hosted by the Cleft Lip and Palate Association United Kingdom) using video screen capture software. The number of posts, comments, unique contributors, and post "likes" was recorded, as well as the type and theme of each post. Data relating to the benefits and challenges of participation in the 2 groups were also collected via an online survey. RESULTS: A content analysis of real-time data identified perioperative care, associated syndromes, and dental health to be particular areas of concern for parents/caregivers. Expectations, experiences, and outcomes of further treatment were key topics of discussion for adults with CL/P. Common benefits of the groups included the ability to connect with others, learn about local events, give and receive emotional support, and obtain quick responses to queries in a semi-anonymous environment. Disadvantages of the groups included a reliance upon opinion rather than medical fact and the frequent use of inappropriate terminology. CONCLUSIONS: Social networking sites appear to be a helpful source of health-related information and peer support for the CL/P population, yet closer monitoring of these groups may be required. PMID- 29570383 TI - Segmental Maxillary Distraction Osteogenesis With a Hybrid-Type Distractor in the Management of Wide Alveolar Cleft. AB - OBJECTIVE: To investigate segmental maxillary distraction osteogenesis (DO) with hybrid-type distractor in the management of wide alveolar cleft. PATIENTS AND METHODS: Six patients underwent segmental DO with a hybrid-type distractor. After the success of DO and 3-month consolidation period, removal of the distractor was accompanied by alveolar bone graft with iliac bone. Panoramic radiograph and computed tomography scanning were taken preoperatively (T0) and the day after distractor removal (T1). The crest distance between the long axis of cleft nearby teeth was measured. RESULT: All patients completed the DO period, and the succeeding alveolar bone graft healing was uneventful. The mean cleft distance decrease was 12.05 mm (range: 10.1-13.5 mm). As for the mobility degree record of abutment tooth in the transport segment recorded, 6 patients were grading I degrees at T0, while 5 patients were grading I degrees and 1 patient was grading II degrees at T1. CONCLUSION: Segmental maxillary DO with the hybrid type distractor is successful to reduce the cleft width in these cases, and it is promising in the treatment of wide dental alveolar cleft, especially for the adult patient. PMID- 29570384 TI - The Effects of Age at Cleft Palate Repair on Middle Ear Function and Hearing Level. AB - OBJECTIVE: To investigate the age effects of cleft palate repair on middle ear function and hearing level in patients who underwent cleft palate repair at different ages by audiologic examination. METHODS: Medical histories were gathered in detail, and audiologic tests (ie, tympanometry and pure tone hearing threshold) were conducted in 126 patients after palatoplasty. The patients were divided into the following 4 groups according to their ages when they underwent cleft palate repair: group I (0-3 years, 73 patients), group II (4-7 years, 29 patients), group III (8-11 years, 16 patients), and group IV (12 years and older, 8 patients). The data regarding tympanograms, hearing levels, and the average hearing thresholds of each group were analyzed using chi-square tests. RESULTS: The prevalence of middle ear dysfunction and hearing loss in the patients who underwent palatoplasty before 3 years old (27.4% and 2.0% respectively) was significantly lower than that in patients who underwent palatopalsty at 12 years or older (75.0% and 43.7%, respectively). Linear-by-linear association revealed that the prevalences of middle ear dysfunction and hearing loss among the 4 groups were significantly different ( P < .05). CONCLUSIONS: The prevalence of middle ear dysfunction and hearing loss tended to increase with advancing age at the time of cleft palate repair. From an audiologist's perspective, palatoplasty at an early age is very beneficial in helping children with cleft palates acquire better middle ear function and hearing level.

PMID- 29570386 TI - Laser interstitial thermal therapy for an eloquent region supratentorial brain lesion. AB - Laser interstitial thermal therapy (LITT) is a minimally invasive stereotactic technique that causes tumor ablation using thermal energy. LITT has shown to be efficacious for the treatment of deep-seated brain lesions, including those near eloquent areas. In this video, the authors present the case of a 62-year-old man with a history of metastatic melanoma who presented with worsening right-sided hemiparesis. MRI revealed a contrast-enhancing lesion in left centrum semiovale in close proximity to corticospinal tracts, consistent with radiation necrosis. The authors review their stepwise technique of LITT with special attention to details for a lesion located near eloquent area. The video can be found here: https://youtu.be/ndrTgi6MXqE . PMID- 29570387 TI - Introduction to Laser Ablation Video Supplement. AB - Laser ablation (also known as laser interstitial thermal therapy [LITT]) has emerged as an important new technology for treating various disorders of the brain and spine. As with any new or emerging technology, there is a learning curve for its optimal use, and video tutorials can be important learning tools to help bridge gaps in knowledge for those who wish to become more familiar with laser ablation. In this special supplement to Neurosurgical Focus, videos illustrate laser ablation's use in the treatment of epilepsy and failed radiosurgery, as well as technical aspects of performing these procedures in eloquent brain and in the spine. We hope that these videos will enable you to enhance your understanding of the evolving use of laser ablation for disorders of the brain or spine. It is the editors' sincere hope that this will be helpful either in your own practice or in determining whether to refer to a neurosurgical colleague experienced in this field. PMID- 29570388 TI - Contemporaneous biopsy and laser interstitial thermal therapy for two treatment refractory brain metastases. AB - Recurrent treatment-refractory brain metastases can be treated with modern adjuvant therapies such as laser interstitial thermal therapy (LITT). Since previously radiated lesions may be indolent (treatment effect) or recurrent tumor, histological confirmation may be helpful. The authors present the utility of contemporaneous biopsy and LITT using intraoperative O-arm navigation in a patient who presented with multiple refractory metastases. The authors demonstrate the utility of O-arm navigation to confirm intraoperative biopsy and LITT placement. Concurrent stereotactic biopsy and LITT may be a safe and efficacious method for both the diagnosis and treatment of deep lesions that are unamenable to standard adjuvant treatment modalities.

AB - Anterior two-thirds corpus callosotomy is a common palliative surgical intervention most commonly employed in patients with atonic or drop seizures. Recently, stereotactic laser ablation of the corpus callosum without a craniotomy has shown promise in achieving similar outcomes with fewer side effects and shorter hospitalizations. The authors demonstrate ablation of the anterior two thirds corpus callosum in a patient with Lennox-Gastaut syndrome and drug resistant drop seizures. Technical nuances of laser ablation with 3 laser fibers are described. Postoperatively, the patient showed a significant reduction in seizure frequency and severity over a 9-month follow-up period.

AB - Acetylcholine (ACh)-synthesizing neurons are major components of the enteric nervous system (ENS). They release ACh and peptidergic neurotransmitters onto enteric neurons and muscle. However, pharmacological interrogation has proven inadequate to demonstrate an essential role for ACh. Our objective was to determine whether elimination of ACh synthesis during embryogenesis alters prenatal viability, intestinal function, the neurotransmitter complement, and the microbiome. Conditional deletion of choline acetyltransferase ( ChAT), the ACh synthetic enzyme, in neural crest-derived neurons ( ChAT-Null) was performed. Survival, ChAT activity, gut motility, and the microbiome were studied. ChAT was conditionally deleted in ENS neural crest-derived cells. Despite ChAT absence, mice were born live and survived the first 2 wk. They failed to gain significant weight in the third postnatal week, dying between postnatal d 18 and 30. Small intestinal transit of carmine red was 50% slower in ChAT-Nulls vs. WT and ChAT- Het. The colons of many neonatal ChAT-Null mice contained compacted feces, suggesting dysmotility. Microbiome analysis revealed dysbiosis in ChAT-Null mice. Developmental deletion of ChAT activity in enteric neurons results in proximal gastrointestinal tract dysmotility, critically diminished colonic transit, failure to thrive, intestinal dysbiosis, and death. ACh is necessary for sustained gut motility and survival of neonatal mice after weaning.-Johnson, C. D., Barlow-Anacker, A. J., Pierre, J. F., Touw, K., Erickson, C. S., Furness, J. B., Epstein, M.

PMID- 29570393 TI - A new role for HERPUD1 and ERAD activation in osteoblast differentiation and mineralization. AB - Bone integrity depends on a finely tuned balance between bone synthesis by osteoblasts and resorption by osteoclasts. The secretion capacity of mature osteoblasts requires strict control of proteostasis. Endoplasmic reticulum associated degradation (ERAD) prevents the accumulation of unfolded ER proteins via dislocation to the cytosol and degradation by the proteasome. The ER membrane protein, homocysteine-inducible endoplasmic reticulum protein with ubiquitin-like domain 1 (HERPUD1), is a key component of the ERAD multiprotein complex which helps to stabilize the complex and facilitate the efficient degradation of unfolded proteins. HERPUD1 expression is strongly up-regulated by the unfolded protein response and cellular stress. The aim of the current study was to establish whether HERPUD1 and ERAD play roles in osteoblast differentiation and maturation. We evaluated preosteoblastic MC3T3-E1 cell and primary rat osteoblast differentiation by measuring calcium deposit levels, alkaline phosphatase activity, and runt-related transcription factor 2 and osterix expression. We found that ERAD and proteasomal degradation were activated and that HERPUD1 expression was increased as osteoblast differentiation progressed. The absence of HERPUD1 blocked osteoblast mineralization in vitro and significantly reduced alkaline phosphatase activity. In contrast, HERPUD1 overexpression activated the osteoblast differentiation program. Our results demonstrate that HERPUD1 and ERAD are important for the activation of the osteoblast maturation program and may be useful new targets for elucidating bone physiology.-Americo-Da-Silva, L., Diaz, J., Bustamante, M., Mancilla, G., Oyarzun, I., Verdejo, H.

AB - Adult intervertebral discs (IVDs) have poor endogenous healing capacity, because of their challenging microenvironment and complex mechanical demands, which can result in painful IVD herniation. There are no regenerative strategies available to improve IVD healing and restore its function. Neonatal mice are excellent models of mammalian regeneration, but there are no studies of the regenerative capacity of neonatal IVDs. In this study, we developed a neonatal model of improved IVD healing to inform repair strategies after herniation. In vivo puncture injuries were performed to simulate herniation with complete annulus fibrosus (AF) tears in caudal IVDs of neonatal (postnatal d 5) and adult (4-6 mo) Scleraxis green fluorescent protein ( ScxGFP) mice. Acute and long-term healing responses were assessed with histologic, radiologic, and biomechanical measurements. Neonates underwent accelerated IVD healing compared to adults with functional restoration and enhanced structural repair after herniation. A population of ScxGFP- cells identified in the neonatal repair site may be associated with this improved healing and warrants future investigation. In summary, function of neonatal IVDs was restored after herniation injury, whereas that of adult discs was not. This improved healing response is likely driven by multiple mechanisms that may include differences in mechanical loading and available repair cells during growth.-Torre, O.

PMID- 29570394 TI - Maternal and umbilical cord serum-derived exosomes enhance endothelial cell proliferation and migration. AB - We investigated the role of exosomes derived from maternal and umbilical cord blood in the regulation of angiogenesis. We report here that both maternal exosomes (MEs) and umbilical exosomes (UEs) significantly enhance HUVEC proliferation, migration, and tube formation. Importantly, ME-treated HUVECs (MEXs) displayed significantly increased migration, but not proliferation or tube formation, compared with UE-treated HUVECs (UEXs). We found that the expression of a subset of migration-related microRNAs (miRNAs), including miR-210-3p, miR 376c-3p, miR-151a-5p, miR-296-5p, miR-122-5p, and miR-550a-5p, among others, were significantly increased or decreased in UEs, and this altered expression was likely correlated with the differential regulation of HUVEC migration. We also found that the mRNA expression of hepatocyte growth factor (HGF) was up-regulated in MEXs and UEXs and, moreover, that inhibiting HGF partially abolished the enhanced cell migration induced by UEs. Our results suggest that both MEs and UEs greatly enhanced endothelial cell (EC) functions and differentially regulated EC migration, which was mostly attributed to the different expression profiles of exosomal miRNA. These findings highlight the importance of exosomes in the regulation of angiogenesis during pregnancy. Exosomal miRNAs, in particular, may be of great significance for the regulation of angiogenesis in maintaining normal pregnancy.-Jia, L., Zhou, X., Huang, X., Xu, X., Jia, Y., Wu, Y., Yao, J., Wu, Y., Wang, K.

PMID- 29570396 TI - Carbon-14 bomb pulse dating shows that tendinopathy is preceded by years of abnormally high collagen turnover. AB - Tendons are essential weight-bearing structures that are often affected by tendinopathy, which leads to pain and impaired mobility. In healthy Achilles tendons, no significant renewal of the weight-bearing collagen matrix seems to occur during adult life, but tendinopathy may lead to increased turnover. The carbon-14 ([14C]) bomb pulse method was used to measure lifelong replacement rates of collagen in tendinopathic and healthy Achilles tendons (tendinopathic: n = 25, born 1937-1972. Healthy: n = 10, born 1929-1966). As expected, the healthy tendon collagen had not been replaced during adulthood, but in tendinopathic tendon, a substantial renewal had occurred. Modeling of the [14C] data suggested that one half of the collagen in tendinopathic matrix had undergone continuous slow turnover for years before the presentation of symptoms. This finding allows for a new concept in tendon pathogenesis because it suggests that either the symptoms of tendinopathy represent a late phase of a very prolonged disease process, or an abnormally high collagen exchange could be a risk factor for tendon disorders rather than being a result of disease.-Heinemeier, K. M., Schjerling, P., Ohlenschlaeger, T. F., Eismark, C., Olsen, J., Kjaer, M. Carbon 14 bomb pulse dating shows that tendinopathy is preceded by years of abnormally high collagen turnover. PMID- 29570395 TI - Eliciting unnatural immune responses by activating cryptic epitopes in viral antigens. AB - Antigenic variation in viral surface antigens is a strategy for escaping the host's adaptive immunity, whereas regions with pivotal functions for infection are less subject to antigenic variability. We hypothesized that genetically invariable and immunologically dormant regions of a viral surface antigen could be exposed to the host immune system and activated by rendering them susceptible to antigen-processing machinery in professional antigen-presenting cells (APCs). Considering the frequent antigen drift and shift in influenza viruses, we identified and used structural modeling to evaluate the conserved regions on the influenza hemagglutinin (HA) surface as potential epitopes. Mutant viruses containing the cleavage motifs of cathepsin S within HA were generated. Immunization of mice showed that the mutant, but not the wild-type virus, elicited specific antibodies against the cryptic epitope. Those antibodies were purified, and specific binding to HA was confirmed. These results suggest that an unnatural immune response can be elicited through the processing of target antigens in APCs, followed by presentation via the major histocompatibility complex, if not subjected to regulatory pathways. By harnessing the antigen processing machinery, our study shows a proof-of-principle for designer vaccines with increased efficacy and safety by either activating cryptic, or inactivating naturally occurring, epitopes of viral antigens.-Lee, Y.

PMID- 29570398 TI - Constraints Imposed by a Natural Landscape Override Offspring Fitness Effects to Shape Oviposition Decisions in Wild Forked Fungus Beetles. AB - Oviposition site decisions often maximize offspring fitness, but costs constraining choice can cause females to oviposit in poor developmental environments. It is unclear whether these constraints cumulatively outweigh offspring fitness to determine oviposition decisions in wild populations. Understanding how constraints shape oviposition in natural landscapes is a critical step toward revealing how maternal behavior influences fundamental phenomena like the evolution of specialization and the use of sink environments. Here, we used a genetic capture-recapture technique to reconstruct the oviposition decisions of individual females in a natural metapopulation of a beetle (Bolitotherus cornutus) that oviposits on three fungus species. We measured larval fitness-related traits (mass, development time, survival) on each fungus and compared the oviposition preferences of females in laboratory versus field tests. Larval fitness differed substantially among fungi, and females preferred a high-quality (high larval fitness) fungus in laboratory trials. However, females frequently laid eggs on the lowest-quality fungus in the wild. They preferred high-quality fungi when moving between oviposition sites, but this preference disappeared as the distance between sites increased and was inconsistent between study plots. Our results suggest that constraints on oviposition preferences in natural landscapes are sufficiently large to drive oviposition in poor developmental environments even when offspring fitness consequences are severe. PMID- 29570397 TI - The tumor secretory factor ZAG promotes white adipose tissue browning and energy wasting. AB - Cachexia is a complex tissue-wasting syndrome characterized by inflammation, hypermetabolism, increased energy expenditure, and anorexia. Browning of white adipose tissue (WAT) is one of the significant factors that contribute to energy wasting in cachexia. By utilizing a cell implantation model, we demonstrate here that the lipid mobilizing factor zinc-alpha2-glycoprotein (ZAG) induces WAT browning in mice. Increased circulating levels of ZAG not only induced lipolysis in adipose tissues but also caused robust browning in WAT. Stimulating WAT progenitors with ZAG recombinant protein or expression of ZAG in mouse embryonic fibroblasts (MEFs) strongly enhanced brown-like differentiation. At the molecular level, ZAG stimulated peroxisome proliferator-activated receptor gamma (PPARgamma) and early B cell factor 2 expression and promoted their recruitment to the PR/SET domain 16 (Prdm16) promoter, leading to enhanced expression of Prdm16, which determines brown cell fate. In brown adipose tissue, ZAG stimulated the expression of PPARgamma and PPARgamma coactivator 1alpha and promoted recruitment of PPARgamma to the uncoupling protein 1 (Ucp1) promoter, leading to increased expression of Ucp1. Overall, our results reveal a novel function of ZAG in WAT browning and highlight the targeting of ZAG as a potential therapeutic application in humans with cachexia.-Elattar, S., Dimri, M., Satyanarayana, A. The tumor secretory factor ZAG promotes white adipose tissue browning and energy wasting. PMID- 29570399 TI - Temperature Drives Epidemics in a Zooplankton-Fungus Disease System: A Trait Driven Approach Points to Transmission via Host Foraging. AB - Climatic warming will likely have idiosyncratic impacts on infectious diseases, causing some to increase while others decrease or shift geographically. A mechanistic framework could better predict these different temperature-disease outcomes. However, such a framework remains challenging to develop, due to the nonlinear and (sometimes) opposing thermal responses of different host and parasite traits and due to the difficulty of validating model predictions with observations and experiments. We address these challenges in a zooplankton-fungus (Daphnia dentifera-Metschnikowia bicuspidata) system. We test the hypothesis that warmer temperatures promote disease spread and produce larger epidemics. In lakes, epidemics that start earlier and warmer in autumn grow much larger. In a mesocosm experiment, warmer temperatures produced larger epidemics. A mechanistic model parameterized with trait assays revealed that this pattern arose primarily from the temperature dependence of transmission rate (beta), governed by the increasing foraging (and, hence, parasite exposure) rate of hosts (f). In the trait assays, parasite production seemed sufficiently responsive to shape epidemics as well; however, this trait proved too thermally insensitive in the mesocosm experiment and lake survey to matter much. Thus, in warmer environments, increased foraging of hosts raised transmission rate, yielding bigger epidemics through a potentially general, exposure-based mechanism for ectotherms. This mechanistic approach highlights how a trait-based framework will enhance predictive insight into responses of infectious disease to a warmer world. PMID- 29570400 TI - Inferring Causalities in Landscape Genetics: An Extension of Wright's Causal Modeling to Distance Matrices. AB - Identifying landscape features that affect functional connectivity among populations is a major challenge in fundamental and applied sciences. Landscape genetics combines landscape and genetic data to address this issue, with the main objective of disentangling direct and indirect relationships among an intricate set of variables. Causal modeling has strong potential to address the complex nature of landscape genetic data sets. However, this statistical approach was not initially developed to address the pairwise distance matrices commonly used in landscape genetics. Here, we aimed to extend the applicability of two causal modeling methods-that is, maximum-likelihood path analysis and the directional separation test-by developing statistical approaches aimed at handling distance matrices and improving functional connectivity inference. Using simulations, we showed that these approaches greatly improved the robustness of the absolute (using a frequentist approach) and relative (using an information-theoretic approach) fits of the tested models. We used an empirical data set combining genetic information on a freshwater fish species (Gobio occitaniae) and detailed landscape descriptors to demonstrate the usefulness of causal modeling to identify functional connectivity in wild populations. Specifically, we demonstrated how direct and indirect relationships involving altitude, temperature, and oxygen concentration influenced within- and between-population genetic diversity of G. occitaniae. PMID- 29570401 TI - Calculating Competitive Intransitivity: Computational Challenges. AB - Intransitive (or "rock-paper-scissors") competition is compelling because it promotes species coexistence and because recent work suggests that it may be common in natural systems. One class of intransitivity indices works by considering s, the minimum number of competitive reversals to convert a given competitive community (i.e., a "tournament") to a hierarchy. The most straightforward example of such "reversal-based" indices is Petraitis's index, [Formula: see text], where M is the maximum s across all possible n-species tournaments. Using exhaustive searches, we prove that Petraitis's formula for M (and, therefore, t) does not hold for [Formula: see text]. Furthermore, determination of s for even moderate values of n may prove difficult, as the equivalent graph theoretical problem is NP (nondeterministic polynomial time) hard; there is no known computationally feasible way to compute an exact answer for anything but small values of n, let alone a closed-form solution. Petraitis's t is a valuable index of intransitivity; however, at present its use is limited to relatively species-poor systems. More broadly, reversal-based indices, while intuitive, may be problematic because of this computability issue. PMID- 29570402 TI - Evolution of Genetic Variance during Adaptive Radiation. AB - Genetic correlations between traits can concentrate genetic variance into fewer phenotypic dimensions that can bias evolutionary trajectories along the axis of greatest genetic variance and away from optimal phenotypes, constraining the rate of evolution. If genetic correlations limit adaptation, rapid adaptive divergence between multiple contrasting environments may be difficult. However, if natural selection increases the frequency of rare alleles after colonization of new environments, an increase in genetic variance in the direction of selection can accelerate adaptive divergence. Here, we explored adaptive divergence of an Australian native wildflower by examining the alignment between divergence in phenotype mean and divergence in genetic variance among four contrasting ecotypes. We found divergence in mean multivariate phenotype along two major axes represented by different combinations of plant architecture and leaf traits. Ecotypes also showed divergence in the level of genetic variance in individual traits and the multivariate distribution of genetic variance among traits. Divergence in multivariate phenotypic mean aligned with divergence in genetic variance, with much of the divergence in phenotype among ecotypes associated with changes in trait combinations containing substantial levels of genetic variance. Overall, our results suggest that natural selection can alter the distribution of genetic variance underlying phenotypic traits, increasing the amount of genetic variance in the direction of natural selection and potentially facilitating rapid adaptive divergence during an adaptive radiation. PMID- 29570404 TI - Neglected Patterns of Variation in Phenotypic Plasticity: Age- and Sex-Specific Antipredator Plasticity in a Cichlid Fish. AB - The ability of organisms to plastically respond to changing environments is well studied. However, variation in phenotypic plasticity during ontogeny is less well understood despite its relevance of being an important source of phenotypic variation in nature. Here, we comprehensively study ontogenetic variation in morphological antipredator plasticity across multiple traits in Pelvicachromis taeniatus, a western African cichlid fish with sexually dimorphic ornamentation. In a split-clutch design, fish were raised under different levels of perceived predation risk (conspecific alarm cues or distilled water). Morphological plasticity varied substantially across ontogeny: it was first observable at an early juvenile stage where alarm cue-exposed fish grew faster. Subsequently, significant plasticity was absent until the onset of sexual maturity. Here, alarm cue-exposed males were larger than control males, which led to deeper bodies, longer dorsal spines, larger caudal peduncles, and increased eye diameters. Sexual ornamentation emerged delayed in alarm cue-exposed males. In later adulthood, the plastic responses receded. Despite small effect sizes, these responses represent putative adaptive plasticity, as they are likely to reduce predation risk. In females, we did not observe any plasticity. In accordance with theory, these results suggest fine-tuned expression of plasticity that potentially increases defenses during vulnerable developmental stages and reproductive output. PMID- 29570403 TI - Venus Flytrap Rarely Traps Its Pollinators. AB - Because carnivorous plants rely on arthropods as pollinators and prey, they risk consuming would-be mutualists. We examined this potential conflict in the Venus flytrap (Dionaea muscipula), whose pollinators were previously unknown. Diverse arthropods from two classes and nine orders visited flowers; 56% of visitors carried D. muscipula pollen, often mixed with pollen of coflowering species. Within this diverse, generalized community, certain bee and beetle species appear to be the most important pollinators, on the basis of their abundance, pollen load size, and pollen fidelity. Dionaea muscipula prey spanned four invertebrate classes and 11 orders; spiders, beetles, and ants were most common. At the family and species levels, few taxa were shared between traps and flowers, yielding a near-zero value of niche overlap for these potentially competing structures. Spatial separation of traps and flowers may contribute to partitioning the invertebrate community between nutritional and reproductive functions in D. muscipula. PMID- 29570405 TI - Model Adequacy and Microevolutionary Explanations for Stasis in the Fossil Record. AB - Long-term phenotypic stasis is frequently observed in the fossil record, but not readily predicted from microevolutionary theory. To test competing explanations for stasis on macroevolutionary timescales we need reliably estimated parameters from appropriate evolutionary models that adequately describe the evolutionary trait dynamics. Here, we develop tests to assess the adequacy of the most commonly used stasis model in evolutionary biology and apply them to time series of phenotypic traits from fossil lineages. Of the 572 fossil time series we analyzed from the literature, 263 time series showed a better fit to the stasis model relative to alternative models, but only 172 of those fitted the stasis model in both relative and absolute terms. The estimated trait variances from these 172 time series do not correlate with rough proxies of effective population size. Our preliminary investigation of the fixed-optimum hypothesis hence fails to give empirical support to the idea that genetic drift around a constant trait optimum is an explanation for stasis in the fossil record. We argue that optima following stationary processes on the adaptive landscape is a viable hypothesis for stasis that needs further investigation. We end by discussing how investigations of model adequacy can be a valuable approach for increasing our understanding of the dynamics of the adaptive landscape on macroevolutionary timescales. PMID- 29570406 TI - Neutral Community Dynamics and the Evolution of Species Interactions. AB - A contemporary goal in ecology is to determine the ecological and evolutionary processes that generate recurring structural patterns in mutualistic networks. One of the great challenges is testing the capacity of neutral processes to replicate observed patterns in ecological networks, since the original formulation of the neutral theory lacks trophic interactions. Here, we develop a stochastic-simulation neutral model adding trophic interactions to the neutral theory of biodiversity. Without invoking ecological differences among individuals of different species, and assuming that ecological interactions emerge randomly, we demonstrate that a spatially explicit multitrophic neutral model is able to capture the recurrent structural patterns of mutualistic networks (i.e., degree distribution, connectance, nestedness, and phylogenetic signal of species interactions). Nonrandom species distribution, caused by probabilistic events of migration and speciation, create nonrandom network patterns. These findings have broad implications for the interpretation of niche-based processes as drivers of ecological networks, as well as for the integration of network structures with demographic stochasticity. PMID- 29570407 TI - The Geometry of Nutrient Space-Based Life-History Trade-Offs: Sex-Specific Effects of Macronutrient Intake on the Trade-Off between Encapsulation Ability and Reproductive Effort in Decorated Crickets. AB - Life-history theory assumes that traits compete for limited resources, resulting in trade-offs. The most commonly manipulated resource in empirical studies is the quantity or quality of diet. Recent studies using the geometric framework for nutrition, however, suggest that trade-offs are often regulated by the intake of specific nutrients, but a formal approach to identify and quantify the strength of such trade-offs is lacking. We posit that trade-offs occur whenever life history traits are maximized in different regions of nutrient space, as evidenced by nonoverlapping 95% confidence regions of the global maximum for each trait and large angles (theta) between linear nutritional vectors and Euclidean distances (d) between global maxima. We then examined the effects of protein and carbohydrate intake on the trade-off between reproduction and aspects of immune function in male and female Gryllodes sigillatus. Female encapsulation ability and egg production increased with the intake of both nutrients, whereas male encapsulation ability increased with protein intake but calling effort increased with carbohydrate intake. The trade-offs between traits was therefore larger in males than in females, as demonstrated by significant negative correlations between the traits in males, nonoverlapping 95% confidence regions, and larger estimates of theta and d. Under dietary choice, the sexes had similar regulated intakes, but neither optimally regulated nutrient intake for maximal trait expression. We highlight the fact that greater consideration of specific nutrient intake is needed when examining nutrient space-based trade-offs. PMID- 29570408 TI - Pluck or Luck: Does Trait Variation or Chance Drive Variation in Lifetime Reproductive Success? AB - While there has been extensive interest in how intraspecific trait variation affects ecological processes, outcomes are highly variable even when individuals are identical: some are lucky, while others are not. Trait variation is therefore important only if it adds substantially to the variability produced by luck. We ask when trait variation has a substantial effect on variability in lifetime reproductive success (LRS), using two approaches: (1) we partition the variation in LRS into contributions from luck and trait variation and (2) we ask what can be inferred about an individual's traits and with what certainty, given their observed LRS. In theoretical stage- and size-structured models and two empirical case studies, we find that luck usually dominates the variance of LRS. Even when individuals differ substantially in ways that affect expected LRS, unless the effects of luck are substantially reduced (e.g., low variability in reproductive life span or annual fecundity), most variance in lifetime outcomes is due to luck, implying that departures from "null" models omitting trait variation will be hard to detect. Luck also obscures the relationship between realized LRS and individual traits. While trait variation may influence the fate of populations, luck often governs the lives of individuals. PMID- 29570409 TI - Constraining the Time Interval for the Origin of Life on Earth. AB - Estimates of the time at which life arose on Earth make use of two types of evidence. First, astrophysical and geophysical studies provide a timescale for the formation of Earth and the Moon, for large impact events on early Earth, and for the cooling of the early magma ocean. From this evidence, we can deduce a habitability boundary, which is the earliest point at which Earth became habitable. Second, biosignatures in geological samples, including microfossils, stromatolites, and chemical isotope ratios, provide evidence for when life was actually present. From these observations we can deduce a biosignature boundary, which is the earliest point at which there is clear evidence that life existed. Studies with molecular phylogenetics and records of the changing level of oxygen in the atmosphere give additional information that helps to determine the biosignature boundary. Here, we review the data from a wide range of disciplines to summarize current information on the timings of these two boundaries. The habitability boundary could be as early as 4.5 Ga, the earliest possible estimate of the time at which Earth had a stable crust and hydrosphere, or as late as 3.9 Ga, the end of the period of heavy meteorite bombardment. The lack of consensus on whether there was a late heavy meteorite bombardment that was significant enough to prevent life is the largest uncertainty in estimating the time of the habitability boundary. The biosignature boundary is more closely constrained. Evidence from carbon isotope ratios and stromatolite fossils both point to a time close to 3.7 Ga. Life must have emerged in the interval between these two boundaries. The time taken for life to appear could, therefore, be within 200 Myr or as long as 800 Myr.

AB - Astrobiology is an inherently interdisciplinary area of study, demanding communication across multiple fields: astronomy, geochemistry, planetary science, and so on. Successful communication requires that researchers be aware of the basic findings, open questions, and tools and techniques of allied fields and possess an appreciation and respect for what these fields consider good science. To facilitate this communication between early-career researchers, the Arizona NExSS Winter School was hosted in February 2016, bringing together graduate students and postdoctoral researchers from backgrounds spanning the field of astrobiology. Students virtually attended a scientific Workshop Without Walls and participated in lectures, discussions, field trips, and hands-on activities, culminating in the writing and review of mock proposals by interdisciplinary teams. We assess the impact of the school on interdisciplinarity using a pre- and posttest survey of 24 students, informed by National Science Foundation impact categories (Friedman et al., 2008 ) within the Impact Analysis Method (IAM) described by Davis and Scalice ( 2015 ). We demonstrate that students gained knowledge, especially in fields outside their home discipline. Furthermore, an underlying disciplinary divide between geochemists and planetary scientists on the role of life in planetary evolution is observed and interpreted. These findings demonstrate that the Arizona NExSS Winter School had measurable impact on interdisciplinarity and that the IAM rubric has utility in measuring impact. We make recommendations for further research to understand the interdisciplinary gaps in astrobiology and how best to bridge them.

PMID- 29570411 TI - Manganese Oxides Resembling Microbial Fabrics and Their Implications for Recognizing Inorganically Preserved Microfossils. AB - In the search for microfossils of early life on Earth, the demonstration of biogenicity is paramount. Traditionally, only syngenetic structures with cellular elaboration, hollow sheaths/cell walls, and indigenous kerogen have been considered bona fide fossils. Recent reports of inorganically preserved microfossils represent a shift from this practice. Such a shift, if accompanied by a robust set of biogenicity criteria, could have profound implications for the identification of biosignatures on early Earth and extraterrestrial bodies. Here, we reaffirm the conventional criteria by examining aggregates of inorganic filaments from the Pilbara region of Western Australia. These aggregates are preserved in bedded chert, and the filaments measure up to 1 MUm in diameter and 100 MUm in length. The aggregates superficially resemble kerogenous microbial fabrics and mycelial organisms. However, the filaments consist of manganese oxide, lack cellular elaboration, and show no evidence for hollow sheaths or cell walls. We conclude that the filaments are fibrous minerals of abiotic origin. The similarities between these pseudofossils and some filamentous fossils highlight the need for strict application of the conventional criteria for recognizing microfossils. In the absence of kerogen, morphologically simple structures should, at least, show evidence of cellular features to be considered bona fide fossils.

PMID- 29570412 TI - Profit-Based Model Selection for Customer Retention Using Individual Customer Lifetime Values. AB - The goal of customer retention campaigns, by design, is to add value and enhance the operational efficiency of businesses. For organizations that strive to retain their customers in saturated, and sometimes fast moving, markets such as the telecommunication and banking industries, implementing customer churn prediction models that perform well and in accordance with the business goals is vital. The expected maximum profit (EMP) measure is tailored toward this problem by taking into account the costs and benefits of a retention campaign and estimating its worth for the organization. Unfortunately, the measure assumes fixed and equal customer lifetime value (CLV) for all customers, which has been shown to not correspond well with reality. In this article, we extend the EMP measure to take into account the variability in the lifetime values of customers, thereby basing it on individual characteristics. We demonstrate how to incorporate the heterogeneity of CLVs when CLVs are known, when their prior distribution is known, and when neither is known. By taking into account individual CLVs, our proposed approach of measuring model performance gives novel insights when deciding on a customer retention campaign. The method is dependent on the characteristics of the customer base as is compliant with modern business analytics and accommodates the data-driven culture that has manifested itself within organizations.

AB - Studies have shown that certain features from geography, demography, trade area, and environment can play a vital role in retail site selection, largely due to the impact they asserted on retail performance. Although the relevant features could be elicited by domain experts, determining the optimal feature set can be intractable and labor-intensive exercise. The challenges center around (1) how to determine features that are important to a particular retail business and (2) how to estimate retail sales performance given a new location? The challenges become apparent when the features vary across time. In this light, this study proposed a nonintervening approach by employing feature selection algorithms and subsequently sales prediction through similarity-based methods. The results of prediction were validated by domain experts. In this study, data sets from different sources were transformed and aggregated before an analytics data set that is ready for analysis purpose could be obtained. The data sets included data about feature location, population count, property type, education status, and monthly sales from 96 branches of a telecommunication company in Malaysia. The finding suggested that (1) optimal retail performance can only be achieved through fulfillment of specific location features together with the surrounding trade area characteristics and (2) similarity-based method can provide solution to retail sales prediction.

AB - Nonstandard insurers suffer from a peculiar variant of fraud wherein an overwhelming majority of claims have the semblance of fraud. We show that state of-the-art fraud detection performs poorly when deployed at underwriting. Our proposed framework "FraudBuster" represents a new paradigm in predicting segments of fraud at underwriting in an interpretable and regulation compliant manner. We show that the most actionable and generalizable profile of fraud is represented by market segments with high confidence of fraud and high loss ratio. We show how these segments can be reported in terms of their constituent policy traits, expected loss ratios, support, and confidence of fraud. Overall, our predictive models successfully identify fraud with an area under the precision-recall curve of 0.63 and an f-1 score of 0.769.

AB - Prescriptive analytics extends on predictive analytics by allowing to estimate an outcome in function of control variables, allowing as such to establish the required level of control variables for realizing a desired outcome. Uplift modeling is at the heart of prescriptive analytics and aims at estimating the net difference in an outcome resulting from a specific action or treatment that is applied. In this article, a structured and detailed literature survey on uplift modeling is provided by identifying and contrasting various groups of approaches. In addition, evaluation metrics for assessing the performance of uplift models are reviewed. An experimental evaluation on four real-world data sets provides further insight into their use. Uplift random forests are found to be consistently among the best performing techniques in terms of the Qini and Gini measures, although considerable variability in performance across the various data sets of the experiments is observed. In addition, uplift models are frequently observed to be unstable and display a strong variability in terms of performance across different folds in the cross-validation experimental setup. This potentially threatens their actual use for business applications. Moreover, it is found that the available evaluation metrics do not provide an intuitively understandable indication of the actual use and performance of a model. Specifically, existing evaluation metrics do not facilitate a comparison of uplift models and predictive models and evaluate performance either at an arbitrary cutoff or over the full spectrum of potential cutoffs. In conclusion, we highlight the instability of uplift models and the need for an application oriented approach to assess uplift models as prime topics for further research. PMID- 29570417 TI - Reduction of Marek's Disease Virus Infection by Toll-Like Receptor Ligands in Chicken Embryo Fibroblast Cells. AB - Evolutionarily conserved pattern recognition receptors, including Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns (PAMPs) that are present in microbes. PAMPs induce several pathways downstream of TLRs that lead to induction of antiviral responses. The objective of this study was to investigate the stimulatory effect of various PAMPs (in the form of TLR ligands) in reducing Marek's disease virus (MDV) infection in chicken embryo fibroblast cells (CEFs). To this end, CEFs were pretreated with Pam3CSK4, Poly(IC), lipopolysaccharide (LPS), and CpG ODN as TLR2, TLR3, TLR4, and TLR21 ligands, respectively for 24 h followed by infection with MDV. The results indicated that pretreatment with Poly(IC) resulted in a robust reduction (by about 81%) of MDV infection in CEFs at 96 h postinfection while a moderate reduction was observed with treatment of Pam3CSK4 (35%), LPS (26%), and CpG ODN (23%) PAMPs. Transcriptional analysis of gene expression in CEFs demonstrated that all TLR ligand treatments and MDV infection significantly increased the expression of type I interferons, interleukin (IL)-1beta, interferon regulatory factor 7 (IRF7), interferon induced protein with tetratricopeptide repeats 5 (IFIT5), and myxoma-resistance protein (Mx). Further studies are needed to explore the mechanism by which PAMPs, particularly the TLR3 ligands could reduce MDV infection in CEFs, which may play an important role in controlling the replication of MDV in chicken.

AB - OBJECTIVE: The purpose of this study was histological and thermometric examination of soft tissue de-epithelialization using digitally controlled laser handpiece (DCLH) - X-Runner. BACKGROUND DATA: Commonly used techniques for de epithelialization include scalpel, abrasion with diamond bur, or a combination of the two. Despite being simple, inexpensive and effective, these techniques are invasive and may produce unwanted side effects. It is important to look for alternative techniques using novel tools, which are minimally invasive and effective. MATERIALS AND METHODS: 114 porcine samples sized 6 * 6 mm were collected from the attached gingiva (AG) of the alveolar process of the mandible using 15C scalpel blade. The samples were irradiated by means of Er:YAG laser (LightWalker, Fotona, Slovenia), using X-Runner and HO2 handpieces at different parameters; 80, 100, and 140 mJ/20 Hz in time of 6 or 16 sec, respectively. The temperature was measured with a K-type thermocouple. For the histopathological analysis of efficiency of epithelium removal and thermal injury, 3 random samples were de-epithelialized with an HO2 handpiece, and 9 random samples with an X Runner handpiece with different parameters. For the samples irradiated with DCLH, we have used three different settings, which resulted in removing 1 to 3 layers of the soft tissue. The efficiency of epithelium removal and the rise of temperature were analyzed. RESULTS: DCLH has induced significantly lower temperature increase compared with HO2 at each energy to frequency ratio. The histological examination revealed total epithelium removal when HO2 handpiece was used at 100 and 140 mJ/20 Hz and when DCLH was used for two- and threefold lasing at 80, 100, and 140 mJ/20 Hz. CONCLUSIONS: Er:YAG laser with DCLH handpiece may be an efficient tool in epithelium removal without excessive thermal damage. PMID- 29570420 TI - Reply to M. Melo et al.

PMID- 29570421 TI - Five-Year Follow-Up of Nivolumab in Previously Treated Advanced Non-Small-Cell Lung Cancer: Results From the CA209-003 Study. AB - Purpose In two phase III studies, nivolumab, a programmed death-1 (PD-1) inhibitor antibody, improved overall survival (OS) versus docetaxel in pretreated advanced non-small-cell lung cancer (NSCLC). We report 5-year follow-up results from an early phase I study of nivolumab in this patient population and describe characteristics of 5-year survivors. Patients and Methods Patients with pretreated, advanced NSCLC received nivolumab 1, 3, or 10 mg/kg every 2 weeks in 8-week cycles for up to 96 weeks. OS from the time of first dose was estimated by the Kaplan-Meier method. Results The estimated 5-year OS rate was 16% for all treated patients (N = 129); 5-year OS rates were similar for squamous (16%) and nonsquamous (15%) NSCLC. Of 16 5-year survivors, most (88%) were known current or former smokers. Of 10 5-year survivors with quantifiable PD-1 ligand 1 expression, 70% had >= 1% PD-1 ligand 1 expression at baseline. Twelve 5-year survivors (75%) achieved a partial response to nivolumab per Response Evaluation Criteria in Solid Tumors, version 1.0, and two each (12%) had stable disease and progressive disease as best response. Nine 5-year survivors (56%) completed the maximum 96 weeks of nivolumab; four (25%) discontinued owing to adverse events and three (19%) owing to disease progression. As of a November 2016 database lock, 12 5-year survivors (75%) received no subsequent therapy and were without evidence of progressive disease at last follow-up. Conclusions Nivolumab treatment resulted in long-term OS and durable responses in a proportion of patients with pretreated advanced NSCLC. Long-term survivors had diverse baseline and on-treatment characteristics. PMID- 29570422 TI - Aging Is a Sticky Business. AB - OBJECTIVE: The objective of this work is to put forward a mechanism by which low level light [red-to near infrared (NIR) laser or light emitting diodes (LED)] is instrumental in the process of accelerating the healing of wounds. BACKGROUND DATA: Interaction modalities of low-level light with oxidatively stressed cells and tissues are the focus of intense research efforts. Several models of the light/cell-interaction mechanism have been proposed. In the most popular model, cytochrome c oxidase is believed to play the role of the principal acceptor for red-to NIR photons. METHODS: Using as an illustrative example the successful LED treatment of an edematous limb ulcer, the results of recent in vitro tests and complementary laboratory experiments are presented and discussed. RESULTS: The most plausible mechanism of biostimulatory effect of red-to NIR light consists of its impact on the nanoscopic interfacial water layers in mitochondria and the extracellular matrix (ECM) where mitochondrial reactive oxygen species (ROS) induce an increase in the viscosity of the water layers bound to the predominantly hydrophilic surfaces in the intramitochondrial space as well as the ECM, where the process progressively propagates with age. The biostimulatory effect of red-to NIR light consists of counteracting the ROS-induced elevation of interfacial water viscosities, thereby instantly restoring the normal mitochondrial function, including the synthesis of adenosine triphosphate (ATP) by the rotary motor (ATP synthase). CONCLUSIONS: An understanding of the mechanism of interaction of red-to NIR light with mitochondria, cells, and tissues safeguards progress in the field of low-level light therapy (LLLT) and puts us in the position to design better therapies. PMID- 29570423 TI - Current and Future Trends in Adipose Stem Cell Differentiation into Neuroglia. AB - BACKGROUND: Neurological diseases and disorders pose a challenge for treatment and rehabilitation due to the limited capacity of the nervous system to repair itself. Adipose stem cells (ASCs) are more pliable than any adult stem cells and are capable of differentiating into non-mesodermal tissues, including neurons. Transdifferentiating ASCs to specific neuronal lineage cells enables us to deliver the right type of cells required for a replacement therapy into the nervous system. METHODS: Several methodologies are being explored and tested to differentiate ASCs to functional neurons and glia with cellular factors and chemical compounds. However, none of these processes and prototypes has been wholly successful in changing the cellular structure and functional status of ASCs to become identical to neuroglial cells. In addition, successful integration and functional competence of these cells for use in clinical applications remain problematic. Photobiomodulation or low-level laser irradiation has been successfully applied to not only improve ASC viability and proliferation but has also shown promise as a possible enhancer of ASC differentiation. CONCLUSIONS: Studies have shown that photobiomodulation improves the use of stem cell transplantation for neurological applications. This review investigates current neuro-differentiation inducers and suitable methodologies, including photobiomodulation, utilizing ASCs for induction of differentiation into neuronal lineages. PMID- 29570426 TI - Evaluation of a new ballistic vest design for compliance with Standard No. PN-V 87000:2011 using physiological tests. AB - Research into newly developed ballistic vests to be worn by police officers under clothing was carried out with air temperature conditions of +20 degrees C. A ballistic vest should incorporate protective features, comfort and ergonomics. The thermal strain on users who wore the vests was evaluated as an average and individually, after they had been conditioned in high (+50 degrees C), low (-40 degrees C) or neutral (+20 degrees C) air temperatures, while performing various occupational activities. Research involved six police officers aged 36-42 years, who wore civilian clothing used in moderate environmental conditions. During the tests, physiological parameters (internal temperature, local skin temperatures and amount of sweat secreted) were determined. The ease of doing exercises while wearing the vests, vest service and level of discomfort in use were assessed. Research showed that the vests tested, both as an average and individually, meet the requirements of Standard No. PN-V-87000:2011 (clause 4.5). PMID- 29570425 TI - A kindergarten-based child health promotion program: the Adapted National Aeronautics and Space Administration (NASA) Mission X for improving physical fitness in South Korea. AB - BACKGROUND: Effective and sustainable intervention programs are needed to promote physical activity (PA) in children. OBJECTIVES: To adapt the NASA Mission X: Train Like an Astronaut program for use with South Korean children, and to evaluate its feasibility and effectiveness for promoting children's physical fitness. METHODS: Children 5 years old ( n = 212) and their parents were recruited from three kindergartens in three cities to participate in a 6-week intervention program in fall 2014. We assessed the children's PA and related changes, and parental changes in attitude and beliefs, after participation in the intervention. RESULTS: Girls reported less PA than boys (40.7 vs. 59.0, p < 0.01). Children with a normal body mass index (BMI) were more likely to be active than underweight children (< 10 percentile) or overweight children (? 85 percentile). After the intervention, about one-half of the children had increased their level of PA (49.4%), increased interest in PA (59.1%) and found psychological need satisfaction in exercise (52.6%). The majority of parents became aware of the necessity of childhood PA (94.2%), their child's PA capability (64.3%), and the relationship of PA with their children's self-esteem (79.9%). CONCLUSIONS: The adapted NASA Mission X program was feasible and effective in promoting PA in kindergarteners, and also improved their parents' attitude and beliefs about children's PA in South Korea. This study provided a model for promoting childhood health through child care and educational settings. PMID- 29570427 TI - "It's Relentless": Providers' Experience of Pediatric Chronic Critical Illness. AB - BACKGROUND: Children with chronic critical illness (CCI), those children with repeated and prolonged hospitalizations along with technology-dependence or multiple organ system involvement, are increasing in number. The intensive daily needs of these children, during hospitalization and at home, affect both clinicians and families. OBJECTIVE: To assess clinician experiences of burnout and clinician perceptions of family burnout in caring for children with CCI. DESIGN: Semistructured interviews with 44 stakeholders known for pediatric CCI expertise were audio-recorded and transcribed. Participants characterized their experiences with provider and family burnout. SETTING/SUBJECTS: Stakeholders were from five metropolitan areas, representing a variety of professions (i.e., inpatient/outpatient clinicians, home health providers, and policy professionals). MEASUREMENTS: Content analysis was performed on interview transcripts. RESULTS: Participants reported that both clinicians and families caring for children with CCI experience some level of burnout, although stakeholders note that families may experience burnout differently than clinicians. Burnout results from the following: (1) escalating daily care needs; (2) intense relationships between clinicians and families; (3) uncertain outcomes; (4) feeling unprepared to care for children with complicated medical needs; and (5) the stress and emotional toll of caring for a child with CCI. CONCLUSIONS: Managing the medical needs of children with CCI can be associated with clinician and parent burnout. Strategies to support clinicians and families are needed to ensure high quality of care for these children, as well as maintain an appropriate number of clinical providers for this vulnerable subset of children with medical complexity. PMID- 29570428 TI - Intravascular Cooling Catheter-Related Venous Thromboembolism After Hypothermia: A Case Report and Review of the Literature. AB - Fifty-four year-old man with recent history of myocardial infarction and a percutaneous coronary intervention who suffered a ventricular fibrillation arrest at home. He was resuscitated in the field. His heart rhythm was in atrial fibrillation. The cardiac catheterization showed a patent stent from his previous myocardial infarction and no new occlusions. He subsequently underwent hypothermia protocol using the Alsius CoolGard 3000 Temperature Control System and Icy Catheter. Heparin drip was started for atrial fibrillation 36 hours after catheter insertion and became therapeutic 2 hours before the end of cooling maintenance phase. Heparin drip was stopped 4 hours into the rewarming phase because of spontaneous conversion to sinus rhythm. Subcutaneous heparin was resumed for deep venous thrombosis prophylaxis. He was extubated to room air after hypothermia protocol. The cooling catheter was removed 88 hours after insertion. Within 1 minute of catheter removal, his oxygen saturation dropped to 80%. Transthoracic echocardiogram showed a mobile thrombus in the right atrium prolapsing into the right ventricle. Computer tomography angiography of the chest confirmed a large saddle embolus. Ninety minutes later, patient went into cardiac arrest with pulseless electrical activity while he was being considered for surgical embolectomy, but he could not be resuscitated. The temporal relationship of the catheter removal and his acute clinical decompensation led to believe that this was an intravascular cooling catheter (ICC)-related event. Providers should be cognizant of the complications of central venous catheters such as thrombosis formation, as it could lead to fatal pulmonary embolism. Physicians should promote frequent assessment of the access site(s) during routine physical examinations and potentially use point of care vascular ultrasound in high-risk cases to rule out a catheter-associated thrombus before catheter removal. PMID- 29570429 TI - Changes in Social Integration Predict Changes in Physical Activity: A 25-Year Prospective Study. AB - BACKGROUND: Social relationships are among the strongest predictors of health. The extent to which one is embedded in social networks, also referred to as social integration, has been associated with physical activity in short-term longitudinal and cross-sectional studies. How changes in social integration impact physical activity over longer periods of time is not well understood. METHODS: Longitudinal data from 5 waves of the Americans' Changing Lives study were used (wave 1: n = 3617; wave 5: n = 1427). Data were modeled using latent growth curves to understand the trajectories of social integration and physical activity, separately. Latent interlocking growth curve methods were used to understand if and how changes in social integration predicted changes in physical activity. RESULTS: Physical activity did not change over the 25-year period (P = .68). Social integration significantly decreased (P = .025). Changes in social integration predicted changes in physical activity (beta = 0.12, P < .05). CONCLUSIONS: Changes in how often adults speak to family and friends predict changes in physical activity across a 25-year period. Group- and social network focused physical activity research, advocacy, and interventions are warranted. PMID- 29570430 TI - Test of Responsiveness and Sensitivity of the Questionnaire "Lymphedema Quality of Life Inventory". AB - BACKGROUND: Lymphedema may affect patients' health-related quality of life (HRQoL) and thus a disease-specific questionnaire is needed. The Lymphedema Quality of life Inventory (LyQLI) has been tested for reliability and validity. The purpose of this study was to test the LyQLI for responsiveness and sensitivity. METHODS AND RESULTS: The study participants were patients with lymphedema in the upper or lower limb, attending a Swedish rehabilitation program (RP) and undergoing conservative treatment without surgery (RP-sample), or undergoing liposuction (LS) in Australia, Scotland, and Sweden (LS-sample). Mean values for the three LyQLI domains (physical, psychosocial, and practical) were calculated before and 1 month after intervention, and the paired t-test was used to detect group differences. Responsiveness was calculated using standardized response mean (SRM), and sensitivity was analyzed with box plots and an independent t-test to detect group differences. Eighteen patients in the RP sample and 50 in the LS-sample were studied, and both samples demonstrated increased HRQoL after intervention. The changes were significant in all domains, except for the practical domain in the RP-sample. The SRM for the three LyQLI domains (physical, psychosocial, and practical) were 0.8, 0.8, and 0.4, respectively, in the RP-sample and 0.7, 1.2, and 0.9 in the LS-sample. Statistical testing indicated that the LyQLI was sensitive enough to reveal differences between patient groups. CONCLUSIONS: LyQLI responsiveness and sensitivity indicated that the tool can be used to evaluate patients undergoing conservative or surgical lymphedema treatments. PMID- 29570432 TI - Transcriptome-seq provides insights into sex-preference pattern of gene expression between testis and ovary of the crucifix crab ( Charybdis feriatus). AB - The crucifix crab, Charybdis feriatus, which mainly inhabits Indo-Pacific region, is regarded as one of the most high-potential species for domestication and incorporation into the aquaculture sector. However, the regulatory mechanisms of sex determination and differentiation of this species remain unclear. To identify candidate genes involved in sex determination and differentiation, high throughput sequencing of transcriptome from the testis and ovary of C. feriatus was performed by the Illumina platform. After removing adaptor primers, low quality sequences and very short (<50 nt) reads, we obtained 80.9 million and 66.2 million clean reads from testis and ovary, respectively. A total of 86,433 unigenes were assembled, and ~43% (37,500 unigenes) were successfully annotated to the NR, NT, Swiss-Prot, KEGG, COG, GO databases. By comparing the testis and ovary libraries, we obtained 27,636 differentially expressed genes. Some candidate genes involved in the sex determination and differentiation of C. feriatus were identified, such as vasa, pgds, vgr, hsp90, dsx-f, fem-1, and gpr. In addition, 88,608 simple sequence repeats were obtained, and 61,929 and 77,473 single nucleotide polymorphisms from testis and ovary were detected, respectively. The transcriptome profiling was validated by quantitative real-time PCR in 30 selected genes, which showed a good consistency. The present study is the first high-throughput transcriptome sequencing of C. feriatus. These findings will be useful for future functional analysis of sex-associated genes and molecular marker-assisted selections in C. feriatus. PMID- 29570431 TI - G protein-coupled receptor kinase-2-deficient mice are protected from dextran sodium sulfate-induced acute colitis. AB - G protein-coupled receptor kinase 2 (GRK2) is a serine/threonine kinase and plays a key role in different disease processes. Previously, we showed that GRK2 knockdown enhances wound healing in colonic epithelial cells. Therefore, we hypothesized that ablation of GRK2 would protect mice from dextran sodium sulfate (DSS)-induced acute colitis. To test this, we administered DSS to wild-type (GRK2+/+) and GRK2 heterozygous (GRK+/-) mice in their drinking water for 7 days. As predicted, GRK2+/- mice were protected from colitis as demonstrated by decreased weight loss (20% loss in GRK2+/+ vs. 11% loss in GRK2+/-). lower disease activity index (GRK2+/+ 9.1 vs GRK2+/- 4.1), and increased colon lengths (GRK2+/+ 4.7 cm vs GRK2+/- 5.3 cm). To examine the mechanisms by which GRK2+/- mice are protected from colitis, we investigated expression of inflammatory genes in the colon as well as immune cell profiles in colonic lamina propria, mesenteric lymph node, and in bone marrow. Our results did not reveal differences in immune cell profiles between the two genotypes. However, expression of inflammatory genes was significantly decreased in DSS-treated GRK2+/- mice compared with GRK2+/+. To understand the mechanisms, we generated myeloid specific GRK2 knockout mice and subjected them to DSS-induced colitis. Similar to whole body GRK2 heterozygous knockout mice, myeloid-specific knockout of GRK2 was sufficient for the protection from DSS-induced colitis. Together our results indicate that deficiency of GRK2 protects mice from DSS-induced colitis and further suggests that the mechanism of this effect is likely via GRK2 regulation of inflammatory genes in the myeloid cells.

PMID- 29570433 TI - Targeted disruption of regulated endocrine-specific protein ( Resp18) in Dahl SS/Mcw rats aggravates salt-induced hypertension and renal injury. AB - Hypertension is a classic example of a complex polygenic trait, impacted by quantitative trait loci (QTL) containing candidate genes thought to be responsible for blood pressure (BP) control in mammals. One such mapped locus is on rat chromosome 9, wherein the proof for a positional candidate gene, regulated endocrine-specific protein-18 ( Resp18) is currently inadequate. To ascertain the status of Resp18 as a BP QTL, a custom targeted gene disruption model of Resp18 was developed on the Dahl salt-sensitive (SS) background. As a result of this zinc-finger nuclease (ZFN)-mediated disruption, a 7 bp deletion occurred within exon 3 of the Resp18 locus. Targeted disruption of Resp18 gene locus in SS rats decreases its gene expression in both heart and kidney tissues regardless of their dietary salt level. Under a high-salt dietary regimen, both systolic and diastolic BP of Resp18mutant rats were significantly increased compared with SS rats. Resp18mutant rats demonstrated increased renal damage, as evidenced by higher proteinuria and increased renal fibrosis compared with SS rats. Furthermore, under a high-salt diet regimen, the mean survival time of Resp18mutant rats was significantly reduced compared with SS rats. These findings serve as evidence in support of Resp18 as a gene associated with the development of hypertension and renal disease. PMID- 29570435 TI - Development of a Surveillance Definition for United States-Mexico Binational Cases of Tuberculosis. AB - OBJECTIVES: Consistently collected binational surveillance data are important in advocating for resources to manage and treat binational cases of tuberculosis (TB). The objective of this study was to develop a surveillance definition for binational (United States-Mexico) cases of TB to assess the burden on US TB program resources. METHODS: We collaborated with state and local TB program staff members in the United States to identify characteristics associated with binational cases of TB. We collected data on all cases of TB from 9 pilot sites in 5 states (Arizona, California, Colorado, New Mexico, and Texas) during January 1-June 30, 2014, that had at least 1 binational characteristic (eg, "crossed border while on TB treatment" and "received treatment in another country, coordinated by an established, US-funded, binational TB program"). A workgroup of US state, local, and federal partners reviewed results and used them to develop a practical surveillance definition. RESULTS: The pilot sites reported 87 cases of TB with at least 1 binational characteristic during the project period. The workgroup drafted a proposed surveillance definition to include 2 binational characteristics: "crossed border while on TB treatment" (34 of 87 cases, 39%) and "received treatment in another country, coordinated by an established, US-funded, binational TB program" (26 of 87 cases, 30%). Applying the new proposed definition, 39 of 87 pilot cases of TB (45%) met the definition of binational. CONCLUSION: Input from partners who were responsible for the care and treatment of patients who cross the United States-Mexico border was crucial in defining a binational case of TB.

PMID- 29570436 TI - Associations Between Comorbid Health Conditions and Quit Outcomes Among Smokers Enrolled in a State Quitline, Arizona, 2011-2016. AB - OBJECTIVE: Smokers with comorbid health conditions have a disproportionate burden of tobacco-related death and disease. A better understanding of differences in quit rates among smokers with comorbid health conditions can guide tailoring of quitline services for subgroups. The objective of this study was to examine self reported tobacco cessation rates among Arizona Smokers' Helpline callers with chronic health conditions (CHCs) and/or a mental health condition (MHC). METHODS: We analyzed data from quitline telephone callers (n = 39 779) who enrolled in and completed at least 1 behavioral counseling session (ie, coaching call). We categorized callers as CHC only (cardiovascular disease/respiratory related/cancer; 32%), MHC only (eg, mood/anxiety/substance dependence; 13%), CHC + MHC (25%), or no comorbid condition (30%). We assessed 30-day abstinence at 7 month follow-up for 16 683 clients (41.9%). We used logistic regression analysis to test associations between comorbidity and quit outcomes after controlling for relevant variables (eg, nicotine dependence). RESULTS: Overall quit rates were 45.4% for those with no comorbid condition, 43.3% for those with a CHC only, 37.0% for those with an MHC only, and 33.3% for those with CHC + MHC. Compared with other groups, the CHC + MHC group had the lowest odds of quitting (adjusted odds ratio = 0.60; 95% confidence interval, 0.52-0.69). CONCLUSION: Having a comorbid condition was associated with lower quit rates, and smokers with co occurring CHCs and MHCs had the lowest quit rates. Quitlines should evaluate more intensive, evidence-driven, tailored services for smoking cessation among callers with comorbid conditions. PMID- 29570441 TI - Restricted exchange microenvironments for cell culture. AB - Metabolite diffusion in tissues produces gradients and heterogeneous microenvironments that are not captured in standard 2D cell culture models. Here we describe restricted exchange environment chambers (REECs) in which diffusive gradients are formed and manipulated on length scales approximating those found in vivo. In REECs, cells are grown in 2D in an asymmetric chamber (<50 MUL) formed between a coverglass and a glass bottom cell culture dish separated by a thin (~100 MUm) gasket. Diffusive metabolite exchange between the chamber and bulk media occurs through one or more openings micromachined into the coverglass. Cell-generated concentration gradients form radially in REECs with a single round opening (~200 MUm diameter). At steady state only cells within several hundred micrometers of the opening experience metabolite concentrations that permit survival which is analogous to diffusive exchange near a capillary in tissue. The chamber dimensions, the openings' shape, size, and number, and the cellular density and metabolic activity define the gradient structure. For example, two parallel slots above confluent cells produce the 1D equivalent of a spheroid. Using REECs, we found that fibroblasts align along the axis of diffusion while MDCK cells do not. MDCK cells do, however, exhibit significant morphological variations along the diffusive gradient. PMID- 29570442 TI - Improved spot morphology for printed glycan arrays. AB - Despite considerable success studying glycan-binding proteins using printed glycan arrays (PGAs), unambiguous quantitation of spot intensities by fluorescent readers remains a challenge. The main obstacles are the varying spot shape and size and in-spot fluorescence distribution caused by uneven drying of the printed drops. Two methods have been suggested for solving this problem: using polymeric glycoconjugates, which makes it possible to equalize the physicochemical properties (hydrophobicity, charge, and size) of different glycans, and applying a glycan solution on a slide coated with a thin oil mask, which hinders evaporation of the drop. Both approaches yield spots with similar sizes and an even distribution of the signal across the spot and are likely to be useful for improving the prints of other classes of molecules. PMID- 29570443 TI - Single step production of Cas9 mRNA for zygote injection. AB - Production of Cas9 mRNA in vitro typically requires the addition of a 5' cap and 3' polyadenylation. A plasmid was constructed that harbored the T7 promoter followed by the EMCV IRES and a Cas9 coding region. We hypothesized that the use of the metastasis associated lung adenocarcinoma transcript 1 (Malat1) triplex structure downstream of an IRES/Cas9 expression cassette would make polyadenylation of in vitro produced mRNA unnecessary. A sequence from the mMalat1 gene was cloned downstream of the IRES/Cas9 cassette described above. An mRNA concentration curve was constructed with either commercially available Cas9 mRNA or the IRES/ Cas9/triplex, by injection into porcine zygotes. Blastocysts were genotyped to determine if differences existed in the percent of embryos modified. The concentration curve identified differences due to concentration and RNA type injected. Single step production of Cas9 mRNA provides an alternative source of Cas9 for use in zygote injections. PMID- 29570444 TI - Thioclava electrotropha sp. nov., a versatile electrode and sulfur-oxidizing bacterium from marine sediments. AB - A taxonomic and physiologic characterization was carried out on Thioclava strain ElOx9T, which was isolated from a bacterial consortium enriched on electrodes poised at electron donating potentials. The isolate is Gram-negative, catalase positive and oxidase-positive; the cells are motile short rods. The bacterium is facultatively anaerobic with the ability to utilize nitrate as an electron acceptor. Autotrophic growth with H2 and S0 (oxidized to sulfate) was observed. The isolate also grows heterotrophically with organic acids and sugars. Growth was observed at salinities from 0 to 10% NaCl and at temperatures from 15 to 41 degrees C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belongs in the genus Thioclava; it had the highest sequence similarity of 98.8 % to Thioclava atlantica 13D2W-2T, followed by Thioclava dalianensis DLFJ1-1T with 98.5 % similarity, Thioclava pacifica TL 2T with 97.7 % similarity, and then Thioclava indica DT23-4T with 96.9 %. All other sequence similarities were below 97 % to characterized strains. The digital DNA-DNA hybridization estimated when compared to T. atlantica 13D2W-2T, T. dalianensis DLFJ1-1T, T. pacifica TL 2T and T. indica DT23-4T were 15.8+/-2.1, 16.7+2.1, 14.3+/-1.9 and 18.3+/-2.1 %. The corresponding average nucleotide identity values between these strains were determined to be 65.1, 67.8, 68.4 and 64.4 %, respectively. The G+C content of the chromosomal DNA is 63.4 mol%. Based on these results, a novel species Thioclava electrotropha sp. nov. is proposed, with the type strain ElOx9T (=DSM 103712T=ATCC TSD-100T). PMID- 29570445 TI - Dokdonia aurantiaca sp. nov., isolated from seaweed Zostera marina. AB - A non-motile, orange-coloured and rod-shaped bacterial strain, designated strain ZOW29T, was isolated from a seaweed sample collected from the South Sea, Republic of Korea. Cells were Gram-stain-negative, aerobic and non-motile. The isolate required sea salts for growth. Carotenoid pigment was produced. A phylogenetic tree based on 16S rRNA gene sequences showed that strain ZOW29T forms an evolutionary lineage within the radiation enclosing the members of the genus Dokdonia with Dokdonia diaphoros MSKK-32T, Dokdonia eikasta PMA-26Tand Dokdonia donghaensis DSW-1T (97.1 % sequence similarity each) as its nearest neighbours. The DNA-DNA relatedness values between strain ZOW29T and these four type strains were 35-48 %. The major fatty acids were iso-C15:0, iso-C17 : 0 3-OH and iso-C15 : 1 G. Strain ZOW29T contained MK-6 and phosphatidylethanolamine, an unidentified aminolipid and an unidentified polar lipid as the only isoprenoid quinone and the major polar lipids, respectively. The DNA G+C content of strain ZOW29T was 38 mol%. On the basis of polyphasic characterization, it is suggested that the isolate represents a novel species of the genus Dokdonia, for which the name Dokdonia aurantiaca sp. nov. (type strain, ZOW29T=KCTC 52956T=JCM 32295T) is proposed.

AB - Accurate identification of Mycobacterium tuberculosis complex (MTBC) isolates is essential for tuberculosis (TB) control, especially in a high-burden country such as Brazil. Conventional identification methods are laborious and time-consuming, while rapid molecular methods are expensive and require skilled personnel and appropriate physical laboratory infrastructure. Immunochromatographic assays (ICAs) have been shown to provide a rapid and reliable TB diagnosis at a low cost. The use of the SD Bioline TB Ag MPT64 ICA (MPT64 assay) for rapid identification of MTBC clinical isolates in the routine diagnosis of a large volume reference TB laboratory was evaluated. We analysed 375 isolates on solid and liquid media concurrently with conventional phenotypic methods, the PRA-hsp65 molecular technique and the MPT64 assay. The sensitivity, specificity and accuracy of the ICA were 97.7, 100 and 98.1 %, respectively. The MPT64 assay yielded rapid and accurate results, enabling the treatment to be initiated early and also impacting on TB control. PMID- 29570447 TI - Aged coconut oil with a high peroxide value induces oxidative stress and tissue damage in mercury-treated rats. AB - Background Exposure to mercury (Hg) and the ingestion of peroxidized edible oil represent a health risk. This study evaluated the effects of peroxidized coconut oil (CO) on the liver and kidney of rats treated with Hg. Methods Male albino Wistar rats were administered HgCl2 and CO separately or as a combination for 21 days. The concentrations of glutathione (GSH) and malondialdehyde (MDA), as well as the activities of superoxide dismutase (SOD) and catalase (CAT), which were used as markers of oxidative stress were measured in the liver and kidney homogenates. The activities of gamma glutamyl transferase (gamma-GT), lactate dehydrogenase (LDH) as well as the levels of bilirubin and creatinine (CREA) as markers of liver and kidney functions were analyzed in the serum. Results The level of MDA in the kidney and liver homogenates was significantly increased in the HgCl2, CO, and CO+HgCl2 groups when compared to control values (p<0.05). Liver SOD activity and GSH level were increased and CAT activity was decreased, whereas kidney GSH level and SOD activity were decreased and CAT activity was increased in the CO and CO+HgCl2 groups when compared to control values (p<0.05). The increase in CREA and bilirubin levels as well as gamma-GT and LDH activities observed in the CO+HgCl2 group when compared to the control values (p<0.05) were associated with pathological changes in both tissues, and were considered to be due to oxidative stress. Conclusions In summary, peroxidized CO and Hg alone or in combination induces oxidative damage in the liver and kidney of rats.

PMID- 29570449 TI - Effects of Trypanosoma brucei brucei infection and diminazene aceturate administration on the blood pressure, heart rate, and temperature of Wistar albino rats. AB - BACKGROUND: This study was carried out to determine the blood pressure changes in experimentally Trypanosoma brucei brucei-infected Wistar albino rats and diminazene aceturate-treated rats. METHODS: Twenty-four rats were purchased and divided into four groups consisting of six rats each. Control group (CON) received 0.5 mL of distilled water, i.m., infected but not treated group (INF) received 2*106 trypanosome/mL i.m., infected but diminazene aceturate-treated group (INFDIM) received 2*106 trypanosome/mL, 3.5 mg/kg, i.m.) and non-infected but diminazene aceturate-treated group (DIM) received 3.5 mg/kg, i.m. and served as negative control. The blood pressures were measured using a CODA 2(r) non invasive blood pressure monitor (Kent Scientific, USA). The results were compiled and statistical analysis was done with significance set at p>=0.05. RESULTS: The values of the blood pressure readings of the Trypanosoma-infected INF (137.0+/ 2.0 mmHg) and diminazene-treated rats INFDIM (125.0+/-7.5 mmHg) when compared to the control group (168.0+/-3.0 mmHg) were significantly lower (p<=0.05) at the end of day 7. The heart rate was also significantly reduced in the INF (403.5+/ 1.5 beats/min) and DIM (445.0+/-24 beats/min) groups of rats when compared with the control group (613.0+/-2.0 beats/min) at the end of day 8. CONCLUSION: The findings indicate the significant reduction in blood pressure and heart rates during Trypanosoma brucei brucei infection and with diminazene aceturate administration. Hence, caution should be exercised when treating trypanosome infected patients with diminazene aceturate.

PMID- 29570453 TI - Anencephaly and obstetric outcome beyond the age of viability. AB - Objective To review the obstetric impact and natural history of anencephalic pregnancies beyond the age of viability. Study design A retrospective chart review of all cases with a prenatal diagnosis of anencephaly who delivered after 24 weeks' gestation during the period 1990 until 2016. Obstetric outcomes including mode of delivery, live births, shoulder dystocia, antepartum haemorrhage (APH), postpartum haemorrhage (PPH) and uterine rupture were studied. Results A total of 42 cases were studied. The average gestational age at diagnosis was 22 weeks (range 10-41). The average gestational age at birth was 36 weeks (range 25-44 weeks). Induction of labour was performed in 55% (23/42) of the cases. Livebirths were documented in 40% (17/42) of the cases. The average birth weight was 1597+/-746 g. The rate of vaginal birth was 69% (29/42), the overall rate of caesarean section was 31% (13/42), with a primary caesarean section in 31% (4/13) and a repeat caesarean section in 69% (9/13) of the patients. There were two cases of shoulder dystocia. No other complications were encountered. Conclusion Overall, anencephaly is not associated with an increased risk of obstetric complications; however, there is a tendency towards delivery via repeated caesarean section in women with a previous uterine scar and anencephaly. The prenatal counselling of potential obstetric outcomes could be of robust value for parents who opt to continue with anencephalic pregnancies. PMID- 29570454 TI - Does ultrasound-guided intervention during repeat cesarean sections improve uterine scar architecture and reduce the number of scars? A prospective controlled clinical intervention trial. AB - Purpose To evaluate whether intraoperative ultrasound-guided detection and resection of the uterine scar during repeat/second cesarean can reduce the number of scars and improve uterine scar architecture. Materials and methods A prospective controlled clinical intervention trial was performed with the following groups: control group 1 (CS1-G): first cesarean; control group 2 (CS2 G): second cesarean utilizing the usual procedure and intervention group (Int-G): repeat/second cesarean with intervention. Transvaginal ultrasound scans were performed 6-9 months after each cesarean. Both primary (double scarring rate) and secondary outcomes [deficiency ratio=d/(b+d)] were analyzed. The deficiency ratio describes the thinning of the remaining myometrium (d=residual myometrial thickness) over the "apparent" defect (b=scar depth). Results In total, 124 of the 156 recruited women were examined, eight were excluded from analysis. The double scarring rate decreased from 42.9% (12/28) in CS2-G to 7.1% (2/28) in the Int-G [difference: 35.8%; 95% confidence interval (CI) (13.2, 54.5); P=0.002]. Two-way analysis of variance (ANOVA) revealed a significant difference between CS2-G and the Int-G in the deficiency ratio adjusted for elective/primary cesareans, with thicker remaining myometrium over the scar defect in the Int-G [difference: -0.24; 95% CI (-0.34, -0.15); P<0.001]. Conclusion Ultrasound-guided resection of the uterine scar area during repeat cesareans reduces the scarring rate and improves thickness of the remaining myometrium as detected by ultrasonography 6-9 months postoperatively. PMID- 29570455 TI - Computerized prediction system for the route of delivery (vaginal birth versus cesarean section). AB - Aim To develop a supportive computerized prediction system for the route of delivery. Materials and methods This study consisted of 2127, 3548 and 1723 deliveries for the years 1976, 1986 and 1996, respectively. We have developed a supervised artificial neural network (ANN) for predicting the delivery route. We have used a back-propagation learning algorithm for this purpose. The data used for the computerized system were obtained during the admission of the patients to the delivery room at the beginning of the first stage of labor after pelvic examination and examination/evaluation of the mother and fetus. The input variables for the ANN were maternal age, gravida, parity, gestational age at birth, necessity and type of labor induction, presentation of the baby at birth, and maternal disorders and/or risk factors. The outputs of the algorithm were vaginal delivery or cesarean section (CS). Results The CS rates in 1976, 1986 and 1996 were 9.1%, 18.5% and 44.5%, respectively. We have demonstrated that the system's specificity and sensitivity were 97.5% and 60.9%, respectively. The false positive rate was 2.5%, whereas the false negative rate was 39.1%. The positive and negative predictive values were 81.8% and 93.1%, respectively. Conclusion Our computerized system, heretofore named as the "Adana System," can be used as a supportive decision-making system for predicting the delivery route. The Adana System might be a useful tool to protect physicians against adverse medicolegal issues. PMID- 29570456 TI - Computer-aided diagnosis of prostate cancer using multi-parametric MRI: comparison between PUN and Tofts models. AB - Computer-aided diagnosis (CAD) systems are increasingly being used in clinical settings to report multi-parametric magnetic resonance imaging (mp-MRI) of the prostate. Usually, CAD systems automatically highlight cancer-suspicious regions to the radiologist, reducing reader variability and interpretation errors. Nevertheless, implementing this software requires the selection of which mp-MRI parameters can best discriminate between malignant and non-malignant regions. To exploit functional information, some parameters are derived from dynamic contrast enhanced (DCE) acquisitions. In particular, much CAD software employs pharmacokinetic features, such as K trans and k ep, derived from the Tofts model, to estimate a likelihood map of malignancy. However, non-pharmacokinetic models can be also used to describe DCE-MRI curves, without any requirement for prior knowledge or measurement of the arterial input function, which could potentially lead to large errors in parameter estimation. In this work, we implemented an empirical function derived from the phenomenological universalities (PUN) class to fit DCE-MRI. The parameters of the PUN model are used in combination with T2 weighted and diffusion-weighted acquisitions to feed a support vector machine classifier to produce a voxel-wise malignancy likelihood map of the prostate. The results were all compared to those for a CAD system based on Tofts pharmacokinetic features to describe DCE-MRI curves, using different quality aspects of image segmentation, while also evaluating the number and size of false positive (FP) candidate regions. This study included 61 patients with 70 biopsy proven prostate cancers (PCa). The metrics used to evaluate segmentation quality between the two CAD systems were not statistically different, although the PUN based CAD reported a lower number of FP, with reduced size compared to the Tofts based CAD. In conclusion, the CAD software based on PUN parameters is a feasible means with which to detect PCa, without affecting segmentation quality, and hence it could be successfully applied in clinical settings, improving the automated diagnosis process and reducing computational complexity. PMID- 29570457 TI - A scalable and deformable stylized model of the adult human eye for radiation dose assessment. AB - With recent changes in the recommended annual limit on eye lens exposures to ionizing radiation, there is considerable interest in predictive computational dosimetry models of the human eye and its various ocular structures including the crystalline lens, ciliary body, cornea, retina, optic nerve, and central retinal artery. Computational eye models to date have been constructed as stylized models, high-resolution voxel models, and polygon mesh models. Their common feature, however, is that they are typically constructed of nominal size and of a roughly spherical shape associated with the emmetropic eye. In this study, we present a geometric eye model that is both scalable (allowing for changes in eye size) and deformable (allowing for changes in eye shape), and that is suitable for use in radiation transport studies of ocular exposures and radiation treatments of eye disease. The model allows continuous and variable changes in eye size (axial lengths from 20 to 26 mm) and eye shape (diopters from -12 to +6). As an explanatory example of its use, five models (emmetropic eyes of small, average, and large size, as well as average size eyes of -12D and +6D) were constructed and subjected to normally incident beams of monoenergetic electrons and photons, with resultant energy-dependent dose coefficients presented for both anterior and posterior eye structures. Electron dose coefficients were found to vary with changes to both eye size and shape for the posterior eye structures, while their values for the crystalline lens were found to be sensitive to changes in only eye size. No dependence upon eye size or eye shape was found for photon dose coefficients at energies below 2 MeV. Future applications of the model can include more extensive tabulations of dose coefficients to all ocular structures (not only the lens) as a function of eye size and shape, as well as the assessment of x-ray therapies for ocular disease for patients with non-emmetropic eyes. PMID- 29570458 TI - 3D printing strategies for peripheral nerve regeneration. AB - After many decades of biomaterials research for peripheral nerve regeneration, a clinical product (the nerve guide), is emerging as a proven alternative for relatively short injury gaps. This review identifies aspects where 3D printing can assist in improving long-distance nerve guide regeneration strategies. These include (1) 3D printing of the customizable nerve guides, (2) fabrication of scaffolds that fill nerve guides, (3) 3D bioprinting of cells within a matrix/bioink into the nerve guide lumen and the (4) establishment of growth factor gradients along the length a nerve guide. The improving resolution of 3D printing technologies will be an important factor for peripheral nerve regeneration, as fascicular-like guiding structures provide one path to improved nerve guidance. The capability of 3D printing to manufacture complex structures from patient data based on existing medical imaging technologies is an exciting aspect that could eventually be applied to treating peripheral nerve injury. Ultimately, the goal of 3D printing in peripheral nerve regeneration is the automated fabrication, potentially customized for the patient, of structures within the nerve guide that significantly outperform the nerve autograft over large gap injuries.

AB - OBJECTIVE: Inspiratory and expiratory muscles are important for effective respiratory function. This study aimed to investigate the efficacy of bedside respiratory muscle training on pulmonary function and stroke-related disabilities in stroke rehabilitation. DESIGN: Patients with stroke (N = 40) in a rehabilitation unit were randomly assigned to either the intervention group (n1 = 20) or the control group (n2 = 20). Both groups participated in a conventional stroke rehabilitation program. During the study period, the intervention group received bedside respiratory muscle training twice a day for 3 wks. The respiratory muscle training consisted of (1) a breath stacking exercise, (2) inspiratory muscle training, and (3) expiratory muscle training. The primary outcomes were measures of pulmonary function: forced vital capacity, forced expiratory volume in 1 sec, and peak flow. Secondary outcomes were stroke-related disabilities assessed using the National Institutes of Health Stroke Scale, Modified Barthel Index, Berg Balance Scale, Fugl-Meyer Assessment, the Korean Mini-Mental State Examination, and pneumonia incidence. RESULTS: Pulmonary function was significantly improved in the intervention group after 3 wks of respiratory muscle training (P < 0.05). This improvement in pulmonary function was independent of the improvement in stroke-related disabilities. CONCLUSION: Three weeks of respiratory muscle training had significant effects on pulmonary function in stroke survivors.

AB - PURPOSE OF REVIEW: Patients with chronic kidney disease (CKD) are at increased risk of atrial fibrillation, stroke, and bleeding posing unique clinical challenges. Novel oral anticoagulants (NOACs) including dabigatran, rivaroxaban, and apixaban have become recognized as alternative therapy to Vitamin K Antagonists (VKA) regarding the prevention of venous thromboembolism (VTE) and reduce the risk of stroke in atrial fibrillation. However, the understanding of NOACs in CKD is still underdeveloped. This review summarizes recent literature on the efficacy and safety of NOACs in patients with CKD. RECENT FINDINGS: Studies focusing on patients with moderate kidney disease were drawn from post hoc analyses from three major NOAC trials, meta-analyses, and postmarketing surveillance studies. Cumulatively, these studies continue to demonstrate NOACs as equivalent if not superior therapies to VKAs in regards to both efficacy and safety. These studies are limited by small sample sizes as well as a lack of direct comparison between NOACs. SUMMARY: The role of NOACs in managing VTE and atrial fibrillation is increasing. Current research suggests that NOACs are at least as efficacious and well tolerated as VKAs. More research is required to elucidate which NOAC is preferable in the clinical setting. PMID- 29570469 TI - Door-to-balloon time and cardiac mortality in acute myocardial infarction by total occlusion of the left circumflex artery. AB - BACKGROUND: Acute myocardial infarction (AMI) caused by total occlusion of the left circumflex artery (LCX) can present as non-ST-segment elevation myocardial infarction (NSTEMI). We evaluate whether door-to-balloon time (DBT) is associated with cardiac mortality in patients with total occlusion of the LCX. PATIENTS AND METHODS: From the Korea Acute Myocardial Infarction Registry, patients with AMI who had total occlusion with a Thrombolysis In Myocardial Infarction flow grade of 0 were included. We determined the factors for delay in primary percutaneous coronary intervention (DBT>90 min) and evaluated cardiac mortality for a median period of 14 months. RESULTS: Mean DBT was 68 min (interquartile range=50-156 min), and the achievement rate of DBT less than or equal to 90 min was 66.9% in the entire study population. More than half of patients with total occlusion of LCX were presented as NSTEMI (57.7%). Among patients with total occlusion of the LCX, the mean DBT was 136 min (interquartile range=60-484 min), and the achievement rate of DBT less than or equal to 90 min was 42.8%. On multivariate analysis, LCX occlusion was an important factor for DBT more than 90 min (odds ratio: 1.766, P<0.001). Among patients with LCX occlusion, cardiac mortality was higher in patients with ST-segment elevation (6.2 vs. 11.0%, P=0.024). CONCLUSION: This study showed that LCX occlusion was a significant factor for the delay in primary percutaneous coronary intervention on account of presenting as NSTEMI. Cardiac mortality was not associated with DBT more than 90 min but with ST-segment elevation in AMI patients with total occlusion of the LCX. PMID- 29570470 TI - The marketing of testosterone treatments for age-related low testosterone or 'Low T'. AB - PURPOSE OF REVIEW: To summarize the research evidence on promotion of testosterone for 'Low T', or age-related hypogonadism. RECENT FINDINGS: Marketing of testosterone for 'Low T' has relied on strategies that are inadequately regulated to prevent off-label promotion, such as unbranded 'disease-awareness' advertising campaigns targeting the general public, sponsored continuing medical education (CME) and ghostwriting. A recent US analysis of television advertising exposure levels versus insurance claims found that both unbranded 'disease awareness' advertising and branded ads were associated with increased rates of testosterone testing, treatment initiation, and treatment without prior testing. Exposes of sponsored CME and ghostwriting indicate misrepresentation of the research evidence on the sequelae of untreated low testosterone and on treatment efficacy. In the United States, advertising to the general public ceased in 2014 after the Food and Drug Administration changed product labeling to clarify that testosterone is only indicated for pathological hypogonadism. Unbranded 'disease awareness' advertising to the general public and 'Low T' messages for health professionals have continued elsewhere. SUMMARY: The review of the experience of promotion of testosterone for 'Low T' and research evidence on effects of advertising targeting the public highlights the need for improved regulation of unbranded 'disease awareness' advertising to ensure adequate protection of public. PMID- 29570471 TI - Retention and adherence: global challenges for the long-term care of adolescents and young adults living with HIV. AB - PURPOSE OF REVIEW: Adolescents living with HIV are the only age group with increasing HIV mortality at a time of global scale-up of access to antiretroviral therapy (ART). As a 'treat all' strategy is implemented worldwide, it is critically important to optimize retention and adherence for this vulnerable group. RECENT FINDINGS: Adolescents and young adults living with HIV have poorer outcomes when compared with adults at each stage of the HIV care cascade, irrespective of income setting. Rates of viral suppression are lowest for adolescents living with HIV, and adherence to ART remains an enormous challenge. High-quality studies of interventions to improve linkage to, and retention in, care on suppressive ART are starkly lacking for adolescents and young adults living with HIV across the globe. However, examples of good practice are beginning to emerge but require large-scale implementation studies with outcome data disaggregated by age, route of infection, and income setting, and include young pregnant women and key populations groups. SUMMARY: There is an urgent need for evidence-based interventions addressing gaps in the adolescent HIV care cascade, including supporting retention in care and adherence to ART.

It most commonly affects white females over the age of 50 and is the most common primary vasculitis in the United States. Treatment of this disease has classically been with high-dose corticosteroids, but this therapy has been associated with severe morbidity and mortality. Tocilizumab, a humanized monoclonal antibody targeting the interleukin-6 receptor, has been used with great efficacy and safety in rheumatoid arthritis and systemic-onset juvenile idiopathic arthritis. As interleukin-6 has been shown to be a key cytokine in giant cell arteritis, the use of an inhibiting agent has been explored. In the 15 case reports/series that were reviewed, most patients were given tocilizumab due to refractory giant cell arteritis and/or intolerance to glucocorticoid therapy, and most experienced remission of symptoms. At this time, there are only 2 randomized control trials to evaluate the efficacy and safety of tocilizumab use in giant cell arteritis. The phase II trial by Villiger et al and the GiACTA trial both showed that tocilizumab greatly increased the rate of sustained remission in giant cell arteritis over the course of 1 year. The most common adverse events were similar to those seen with use in rheumatoid arthritis: infections, neutropenia, and increases in lipids and liver function test enzymes. Based on the results of numerous case studies and the 2 randomized control trials, tocilizumab is the first agent to be approved by the Food and Drug Administration for treatment of giant cell arteritis. PMID- 29570476 TI - Patent Foramen Ovale and Hypoxemia. AB - Patent foramen ovale (PFO), an embryonic remnant of the fetal circulation, is present in 20-25% of adults. Although recent observational studies and clinical trials have established the link between PFO-mediated right-to-left shunting with cryptogenic stroke and migraine with aura, the role of a PFO in exacerbating hypoxemic medical conditions (ie, sleep apnea, chronic obstructive pulmonary disease, pulmonary hypertension, platypnea-orthodeoxia, pulmonary arteriovenous malformation, high-altitude pulmonary edema, and exercise desaturation) remains less understood. PFO-mediated hypoxemia occurs when deoxygenated venous blood from the right atrium enters and mixes with oxygenated arterial blood in the left atrium. Patients with an intracardiac right-to-left shunt may have profound hypoxemia out of proportion to underlying primary lung disease, even in the presence of normal right-sided pressures. The presence of right-to-left cardiac shunting can exacerbate the degree of hypoxemia in patients with underlying pulmonary disorders. In a subset of these patients, percutaneous PFO closure may result in marked improvement in dyspnea and hypoxemia. This review discusses the association between PFO-mediated right-to-left shunting with medical conditions associated with hypoxemia and explores the role of percutaneous PFO closure in alleviating the hypoxemia. PMID- 29570478 TI - Serum Exoglycosidases in Children and Adolescents With Harmful Alcohol Use. AB - OBJECTIVE: There is a lack of accurate alcohol-use biomarkers in children/adolescents due to a short drinking duration/rapid normalization of elevated markers. We checked if lysosomal exoglycosidases, elevated earlier in binge-drinking young adults, can be applicable in children/adolescents as markers of harmful alcohol use. METHODS: The serum activities (pKat/mL) of alpha fucosidase (FUC), beta-galactosidase (GAL), beta-glucuronidase (GLU), beta hexosaminidase (HEX; its HEX A and HEX B isoenzymes), and alpha-mannosidase (MAN) were determined in 20 healthy controls (C) and 25 children/adolescents with harmful alcohol use (intoxicated by alcohol at hospital admission -AI1 and on the next day -AI2). RESULTS: The serum HEX A and alanine aminotransferase (ALT) activity was significantly higher in the AI1 group than in the control. The activities of FUC, GAL, GLU, HEX B, and MAN were lower in the AI group. We found fair and poor accuracy, respectively, for increased enzymes HEX A and ALT. We found fair accuracy for decreased HEX B (AI1) and MAN (AI1), good accuracy for GLU (AI2), FUC (AI2), GAL (AI1, AI2), MAN (AI2), and excellent for FUC (AI1). Correlations were found: ALT with C-reactive protein (CRP), HEX A with white blood cell (WBC) count, blood alcohol concentration with FUC, MAN and HEX B, and WBC with FUC. CONCLUSIONS: Decreased FUC, GLU, GAL, MAN values, and especially FUC (AI1) have the potential to be markers of harmful alcohol use in children/adolescents. The raised activity of HEX A and ALT points to the need for further research to check another inflammatory agent as potential alcohol marker in children and adolescents. Samples need to be collected before intravenous fluid therapy. PMID- 29570477 TI - Is Preconception Substance Use Associated With Unplanned or Poorly Timed Pregnancy? AB - OBJECTIVE: Unplanned and poorly timed pregnancies are associated with adverse maternal and neonatal outcomes. Further understanding of preconception substance use with unplanned and poorly timed pregnancy is warranted. METHODS: Data were analyzed from a prospective study enrolling women early in pregnancy. Preconception tobacco, alcohol, marijuana, opioid, and cocaine use was ascertained. Participants reported whether their current pregnancy was planned and whether it was a good time to be pregnant. Multivariable logistic regression modeling generated risk estimates for preconception substance use, and pregnancy planning and timing, adjusting for confounders. RESULTS: Overall, 37.2% reported unplanned pregnancy, 13.0% poorly timed pregnancy, and 39.0% reported either unplanned and/or poorly timed pregnancy. Within 6 months preconception, one-fifth (20.2%) reported nicotine cigarette use. In the month before conception, 71.8% reported alcohol use, 6.5% marijuana, and approximately 1% opioid or cocaine use. Multivariable analysis demonstrated preconception opioid use was associated with increased odds of poorly timed pregnancy (odds ratio [OR] 2.87, 95% confidence interval [CI] 1.03-7.99). Binge drinking the month before conception was associated with increased odds of poorly timed pregnancy and unplanned pregnancy (OR 1.75, 95% CI 1.01-3.05; and OR 1.68, 95% CI 1.01-2.79, respectively). Marijuana use 2 to 3 times in the month preconception was associated with increased risk of unplanned pregnancy, and unplanned and/or poorly timed pregnancy compared with nonuse (OR 1.78, 95% CI 1.03-3.08; and OR 1.79, 95% CI 1.01-3.17, respectively). Preconception tobacco or cocaine use was not associated with unplanned or poorly timed pregnancy following adjustment. CONCLUSIONS: We demonstrate increased odds of unplanned or poorly timed pregnancy among women with preconception binge drinking, marijuana use, and opioid use; however, no association is observed with other substances after multivariable adjustment, including tobacco. Further research to evaluate high-level preconception substance use and substance disorders with pregnancy planning and timing is warranted. Focused efforts optimizing preconception health behaviors and reducing risk of unplanned or poorly timed pregnancy are needed. PMID- 29570479 TI - Effects of arm elevation on radial artery pressure: a new method to distinguish hypovolemic shock and septic shock from hypotension. AB - OBJECTIVES: In this prospective observational study, we investigated the variability in radial artery invasive blood pressure associated with arm elevation in patients with different hemodynamic types. PATIENTS AND METHODS: We carried out a prospective observational study using data from 73 general anesthesia hepatobiliary postoperative adult patients admitted to an ICU over a 1 year period. A standard procedure was used for the arm elevation test. The value of invasive radial arterial pressure was recorded at baseline, and 30 and 60 s after the arm had been raised from 0 degrees to 90 degrees . We compared the blood pressure before versus after arm elevation, and between hemodynamically stable, hypovolemic shock, and septic shock patient groups. RESULTS: In all 73 patients, systolic arterial pressure (SAP) decreased, diastolic arterial pressure (DAP) increased, and pulse pressure (PP) decreased at 30 and 60 s after arm elevation (P<0.01), but the mean arterial pressure (MAP) was unchanged (P>0.05). On comparing 30 and 60 s, there was no significant difference in SAP, DAP, PP, or MAP (P>0.05). In 40 hemodynamically stable patients, SAP and PP decreased, and DAP and MAP increased significantly at 30 and 60 s after arm elevation compared with baseline (P<0.01). In 16 hypovolemic patients, SAP, DAP, and MAP increased significantly compared with baseline at 30 and 60 s (P<0.01), but PP was unchanged (P>0.05). In 17 patients with septic shock, SAP, PP, and MAP decreased significantly versus baseline at 30 and 60 s (P<0.01), but DAP was unchanged (P>0.05). Comparison of the absolute value of pressure change of septic shock patients at 30 s after raising the arm showed that SAP, DAP, and MAP changes were significantly lower compared with those in hypovolemic shock and hemodynamically stable patients (P<0.01). The areas under the receiver operator characteristic curve for predicting septic shock was 0.930 [95% confidence interval (CI): 0.867 0.992, P< 0.001] for change value at 30 s after arm elevation of SAP. The best cut-off point for the SAP change value was -5 mmHg or less, with a sensitivity of 94.12%, a specificity of 80.36%, a positive likelihood ratio of 4.79 (95% CI: 2.8 8.2), and a negative likelihood ratio of 0.073 (95% CI: 0.01-0.5). CONCLUSION: Our study shows that hypovolemic shock and septic shock patients have significantly different radial artery invasive blood pressure changes in an arm elevation test, which could be applied as a new method to distinguish hypovolemic shock and septic shock from hypotension. PMID- 29570480 TI - Evaluation of D-dimer levels in patients with prosthetic valve thrombosis: relationship with thrombus burden and cerebrovascular events. AB - : Plasma D-dimer level is an indicator of thrombosis and endogenous fibrinolytic activity. We investigated the association between the D-dimer levels and thrombus burden and cerebrovascular events in patients with obstructive prosthetic valve thrombosis (PVT). This retrospective study included 47 patients with obstructive left-sided PVT and 32 controls in whom PVT was excluded with comprehensive transthoracic and transesophageal echocardiography (TEE). The patient group included 11 aortic, 27 mitral, and 9 aortic and mitral valve PVT patients and the control group included 2 aortic, 25 mitral, and 5 aortic and mitral valve patients. Laboratory analysis including plasma D-dimer levels was performed at the time of admission in all patients. The baseline characteristics were similar between the two groups. The plasma D-dimer levels were significantly higher in patients with obstructive PVT compared with controls [680 (110-3590) vs. 310 (80 380) MUg/l; P < 0.001]. By multivariate logistic regression analysis high D-dimer level, low-INR value on admission, high NYHA functional class and recent history of cerebrovascular accident (CVA), and transient ischemic attack (TIA) were the independent predictors of obstructive PVT. A plasma D-dimer level of greater than 365 MUg/l predicted the presence of PVT with a sensitivity of 81% and a specificity of 69% (AUC= 0.781, P < 0.001). Plasma D-dimer levels were significantly higher in patients with a recent history of CVA/TIA [2140 (470 2980) vs. 590 (380-830) MUg/l; P = 0.021]. In addition to the so-called indicators of PVT including subtherapeutic anticoagulation, increased D-Dimer levels may strengthen the suspicion of PVT. Moreover, higher plasma D-dimer levels were associated with higher thrombus burden and higher prevalence of recent CVA/TIA. PMID- 29570481 TI - Intraoperative blood pressure levels in young and anaesthetised children: are we getting any closer to the truth? AB - PURPOSE OF REVIEW: Blood pressure is a basic feature of monitoring during anaesthesia. However, it is very unclear what blood pressures are normal during anaesthesia in children. Furthermore, the clinical consequences of low blood pressure are also uncertain. Similarly, it is unclear when to initiate therapy for hypotension during anaesthesia. This review summarizes the most recent development on the interpretation of blood pressure measurements in children and the relation of low blood pressure to clinical outcome. RECENT FINDINGS: Recently published (multicentre) database studies show that alleged complications of intraoperative hypotension (brain ischaemia, kidney dysfunction, myocardial ischaemia and multiple organ dysfunction) are very rare in children after anaesthesia noncardiac procedures. Furthermore, other studies show that a considerable number of patients have blood pressure lower than a threshold according to the current standards treatment of Paediatric Life Support. SUMMARY: The recently published reference tables can guide anaesthesiologist in daily practice to define intraoperative hypotension. However, there are situations in which a higher blood pressure is recommendable and an individual approach is required. PMID- 29570482 TI - Postmortem Cholesterol Levels in Peripheral Nerve Tissue: Preliminar Considerations on Interindividual and Intraindividual Variation. AB - The study reports the evolution of the demyelinization process based on cholesterol ([CHOL]) levels quantified in median nerve samples and collected at different times-from death from both right and left wrists. The statistical data show that the phenomenon evolves differently in the right and left nerves. Such a difference can reasonably be attributed to a different multicenter evolution of the demyelinization. For data analysis, the enrolled subjects were grouped by similar postmortem intervals (PMIs), considering 3 intervals: PMI < 48 hours, 48 hours < PMI < 78 hours, and PMI > 78 hours. Data obtained from tissue dissected within 48 hours of death allowed for a PMI estimation according to the following equations: PMI = 0.000 + 0.7623 [CHOL]right (R = 0.581) for the right wrist and PMI = 0.000 + 0.8911 [CHOL]left (R = 0.794) for the left wrist.At present, this correlation cannot be considered to be definitive because of the limitation of the small size of the samples analyzed, because the differences in the sampling time and the interindividual and intraindividual variation may influence the demyelinization process. PMID- 29570483 TI - Sudden and Unexpected Death During Sexual Activity, Due to a Glial Cyst of the Pineal Gland. AB - Cysts of the pineal gland are benign lesions. Often asymptomatic, in the majority of cases they are discovered incidentally during brain magnetic resonance imaging or autopsy. Sporadically, however, they may cause such symptoms as chronic headache, loss of consciousness, corticospinal and sensory impairment, and, in some cases, even sudden death. A 45-year-old woman, in apparently good health, collapsed and died suddenly, after reaching orgasm while engaged in sexual intercourse. According to the circumstantial account of her relatives, the woman suffered from severe headaches, which were exacerbated by certain types of physical strain, such as sexual activity. Postmortem examination revealed no external injuries or internal diseases except for a cystic lesion of the pineal gland. Microscopically, the wall of the cyst consisted of a layer of glial tissue surrounded by an area of pineal elements. A complete forensic approach concluded that the cause of death was fatal cardiorespiratory failure resulting from midbrain compression due to a nonneoplastic pineal gland cyst, exacerbated by sexual activity. In this case, the intracranial pressure increase, secondary to Valsalva maneuver during climax, may further aggravate compression on the brainstem, thus concurring to determine the death. PMID- 29570484 TI - A Forensic Approach to Sotos Syndrome. AB - Sotos syndrome is a childhood overgrowth condition that is caused by deletions or mutations in the NSD1 gene located on chromosome 5q35. The syndrome is associated with a wide variety of features that may result in sudden death. The aim of this report was to investigate the spectrum of potential findings in cases presenting to autopsy. A 4-month-old girl with Sotos syndrome was found dead after being put down to sleep. Her death was due to complex cardiac disease that included surgically repaired atrial and ventricular septal defects and valve abnormalities, with cardiomegaly. If the features of Sotos syndrome are identified de novo at autopsy, genetic investigations are warranted, although the recurrence risk is low. The involvement of a clinical geneticist may assist in evaluating cases, and postmortem imaging studies may provide useful information.

AB - Psychosocial causes of suicidal ideation among those who do not have diagnosable mental illnesses remain largely unexplored. Synthesizing the strain theory of suicide and self-determination theory, this research tested a multiple mediator model linking psychological strain with suicidal ideation via three basic psychological need satisfaction. Data from 750 professional employees in China support for the partially mediated effects of psychological strain via need satisfaction of competence and relatedness. These findings contribute to understanding Chinese employees' suicidal ideation from positive psychology perspective that is distinct from what is known from psychopathology.

AB - BACKGROUND: Kathon CG is a commonly used cosmetic-grade preservative that contains active ingredients methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI). OBJECTIVE: The aim of the study was to perform a skin sensitization induction risk assessment of daily exposure to Kathon CG after use of various personal care and cosmetic products. METHODS: We calculated an estimated daily consumer exposure level for rinse-off and leave-on products using the amount of product applied per application, number of applications per day, a retention factor, the MCI/MI concentration, and body surface area values. We assumed that the products contained the maximum recommended safe concentration of MCI/MI: 15 ppm in rinse-off products and 7.5 ppm in leave-on products. We compared estimated consumer exposure levels with the no expected sensitization induction level for MCI/MI and applied sensitization assessment factors to calculate product-specific margins of safety (MOSs). CONCLUSIONS: The MOSs for rinse-off products ranged from 5 to 63, whereas the MOSs for leave-on products ranged from 0.03 to 1.49. Overall, our results provide evidence that some leave on products containing the maximum recommended safe concentration of Kathon CG may increase the risk of sensitization induction due to exposure to MCI/MI. In contrast, rinse-off products were not associated with a potential increased risk of skin sensitization induction. PMID- 29570490 TI - Patch Testing in a Patient on Dupilumab. PMID- 29570491 TI - Characteristics and outcome for heart failure patients with mid-range ejection fraction. AB - AIMS: The aim of this study was to compare precipitants, presenting symptoms and outcomes of patients with heart failure and mid-range ejection fraction (HFmrEF), heart failure and preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) in an Australian cohort. METHODS: We divided 5236 patients in the Management of Cardiac Failure program in Northern Sydney Australia, into HFmrEF (n = 780, 14.9%), HFpEF (n = 1956, 37.4%) and HFrEF (n = 2500, 47.8%), using a cutoff left ventricular ejection fraction of 40-49, at least 50 and less than 40%, respectively. RESULTS: For most characteristics, the HFmrEF patients were intermediate. Hypertension among the HFrEF, HFmrEF and HFpEF groups was present in 50.6, 61.7 and 68.9%, respectively; age more than 85 years was present in 35.1, 37.6 and 42.2%; atrial fibrillation in 35.3, 44.2 and 49.9%; and elevated serum creatinine (>100 MUmol/l) in 59.2, 55.6 and 51.0%. For ischemic heart disease and ischemia as a precipitant of admission, HFmrEF patients were similar to the HFrEF group, and more common than in HFpEF. Mortality rates were not significantly different between the three groups. Readmission rates were highest for HFpEF (40.2%), followed by HFmrEF (42.4%) and HFrEF (45.4%), largely due to differences in nonheart failure readmission. CONCLUSION: Clinically, HFmrEF represents an intermediate phenotype, with the exception of resembling HFrEF with a higher incidence of ischemic heart disease. PMID- 29570492 TI - When do coinfections matter? AB - PURPOSE OF REVIEW: Advances in diagnostic methods mean that coinfections are increasingly being detected in clinical practice, yet their significance is not always obvious. In parallel, basic science studies are increasingly investigating interactions between pathogens to try to explain real-life observations and elucidate biological mechanisms. RECENT FINDINGS: Coinfections may be insignificant, detrimental, or even beneficial, and these outcomes can occur through multiple levels of interactions which include modulation of the host response, altering the performance of diagnostic tests, and drug-drug interactions during treatment. The harmful effects of chronic coinfections such as tuberculosis or Hepatitis B and C in association with HIV are well established, and recent studies have focussed on strategies to mitigate these effects. However, consequences of many acute coinfections are much less certain, and recent conflicting findings simply highlight many of the challenges of studying naturally acquired infections in humans. SUMMARY: Tackling these challenges, using animal models, or careful prospective studies in humans may prove to be worthwhile. There are already tantalizing examples where identification and treatment of relevant coinfections seems to hold promise for improved health outcomes.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. http://creativecommons.org/licenses/by/4.0. PMID- 29570493 TI - Does anthrax antitoxin therapy have a role in the treatment of inhalational anthrax? AB - PURPOSE OF REVIEW: Inhalational anthrax is a rare disease and Bacillus anthracis is a likely pathogen to be used in a biological attack. The lack of clinical experience with anthrax has led experts to develop treatment guidelines. These guidelines recommend anthrax antitoxin to be used in conjunction with antibiotics for the treatment of patients with systemic anthrax infection, yet there is still a lack of human or animal data to support this recommendation. RECENT FINDINGS: The U.S. Food and Drug Administration-approved anthrax antitoxins in 2012, 2015, and 2016. These products have been stockpiled for use in a public health emergency. Although efficacy is high when given early, their efficacy diminishes quickly when given after the development of bacteremia. Animal studies showing a significant incremental benefit of antitoxin therapy when combined with antibiotic therapy were not required by the U.S. Food and Drug Administration for product approval. SUMMARY: There is no conclusive evidence demonstrating that anthrax antitoxin therapy, when combined with a therapeutic course of antibiotics provides a survival benefit in inhalational anthrax. Additional research is needed in improved anthrax-antitoxin therapies, novel small molecule toxin inhibitors that act intracellularly, and studies of supportive care such as hemodynamic and ventilatory support, to improve the survival for inhalational anthrax patients and help mitigate the threat caused by the misuse of B. anthracis. PMID- 29570494 TI - The impact of paediatric antimicrobial stewardship programmes on patient outcomes. AB - PURPOSE OF REVIEW: Although there has been an unprecedented global effort to reduce the spread of antimicrobial resistance, little emphasis has been placed on children. This review aims to evaluate the impact of paediatric antimicrobial stewardship programmes as well as providing a practical approach for effectively implementing them in community-based settings and in hospitals. RECENT FINDINGS: Although rates of serious bacterial infection are low in children, the rates of antimicrobial use and resistance are comparable with adults. Different strategies are required to implement antimicrobial stewardship in community-based settings compared to in hospitals. Nationally coordinated, whole-system approaches have achieved long-term, sustainable reductions in antimicrobial prescribing, as well as reductions in resistance rates at population level, with no evidence of an increase in rate of serious infection or bacterial complications. SUMMARY: Antimicrobial stewardship programmes in neonates and children have unique characteristics and issues. There is currently no consensus on how to measure consumption of antimicrobials in neonates and children. This is a research priority. Benchmarking and clinical networks in neonates and paediatrics are important to share practice and drive best use of antimicrobials. PMID- 29570496 TI - Taste alterations and cancer treatment. AB - PURPOSE OF REVIEW: In this review, we explore issues on the physiology of taste and smell and we critically review recent literature of taste and smell changes and the impact on food preferences throughout the cancer treatment trajectory. RECENT FINDINGS: Subjective measurements such as validated questionnaires can be valuable for the clinical setting and many studies describe taste and smell changes by self-report. Because both smell and taste are interrelated, these subjective results are difficult to interpret. Recent studies have looked more specifically at one type of malignancy with a consistent and homogeneous treatment with chemotherapy using objective taste assessment such as electrogustometry, liquid tastants or filter paper strips. SUMMARY: Taste is a combination of different sensations: smell, texture, temperature and saliva play an important role in determining the overall flavor of food. The mechanism for taste and smell abnormalities in cancer patients treated with systemic therapies remains unclear. PMID- 29570495 TI - The impact of malnutrition on childhood infections. AB - PURPOSE OF REVIEW: Almost half of all childhood deaths worldwide occur in children with malnutrition, predominantly in sub-Saharan Africa and South Asia. This review summarizes the mechanisms by which malnutrition and serious infections interact with each other and with children's environments. RECENT FINDINGS: It has become clear that whilst malnutrition results in increased incidence, severity and case fatality of common infections, risks continue beyond acute episodes resulting in significant postdischarge mortality. A well established concept of a 'vicious-cycle' between nutrition and infection has now evolving to encompass dysbiosis and pathogen colonization as precursors to infection; enteric dysfunction constituting malabsorption, dysregulation of nutrients and metabolism, inflammation and bacterial translocation. All of these interact with a child's diet and environment. Published trials aiming to break this cycle using antimicrobial prophylaxis or water, sanitation and hygiene interventions have not demonstrated public health benefit so far. SUMMARY: As further trials are planned, key gaps in knowledge can be filled by applying new tools to re-examine old questions relating to immune competence during and after infection events and changes in nutritional status; and how to characterize overt and subclinical infection, intestinal permeability to bacteria and the role of antimicrobial resistance using specific biomarkers. PMID- 29570497 TI - Radiation Exposure and Health Risks for Orthopaedic Surgeons. AB - Orthopaedic surgeons are routinely exposed to intraoperative radiation and, therefore, follow the principle of "as low as reasonably achievable" with regard to occupational safety. However, standardized education on the long-term health effects of radiation and the basis for current radiation exposure limits is limited in the field of orthopaedics. Much of orthopaedic surgeons' understanding of radiation exposure limits is extrapolated from studies of survivors of the atomic bombings in Hiroshima and Nagasaki, Japan. Epidemiologic studies on cancer risk in surgeons and interventional proceduralists and dosimetry studies on true radiation exposure during trauma and spine surgery recently have been conducted. Orthopaedic surgeons should understand the basics and basis of radiation exposure limits, be familiar with the current literature on the incidence of solid tumors and cataracts in orthopaedic surgeons, and understand the evidence behind current intraoperative fluoroscopy safety recommendations. PMID- 29570498 TI - Routine Plain Radiographs in the Setting of Atraumatic Shoulder Pain: Are They Useful? AB - INTRODUCTION: Plain radiographs of the shoulder are routinely obtained for patients presenting with atraumatic shoulder pain. The diagnostic utility of these radiographs is debatable. METHODS: Patients presenting for the first time to a shoulder clinic with atraumatic shoulder pain received a plain radiographic series. After considering their medical history and physical examination, we made a preliminary diagnosis and formulated a tentative treatment plan. We then reviewed the radiographs and determined whether the addition of these radiographs altered the diagnosis and/or treatment. RESULTS: A total of 343 patients met the inclusion criteria. Age >50 years (odds ratio, 3.3; 95% confidence interval, 1.9 to 5.8; P < 0.00001) and weakness in forward elevation (odds ratio, 2.9; 95% confidence interval, 1.6 to 5.4; P = 0.0003) were associated with the presence of radiographic findings. Plain radiographs altered the proposed diagnosis in only 14.9% (51/343) of cases. However, clinical management was changed in only 1.7% of cases. Plain radiographs had no effect on clinical management in 97.4% of patients younger than 50 years. DISCUSSION: Plain radiographs rarely alter the diagnosis or affect management in the setting of atraumatic shoulder pain, particularly in patients younger than 50 years. Patients may be exposed to unnecessary radiation, and the healthcare system as a whole may be burdened with the increased cost of this imaging modality. LEVEL OF EVIDENCE: Level II (diagnostic). PMID- 29570499 TI - Ketamine effects on mammalian target of rapamycin signaling in the mouse limbic system depend on functional dopamine D3 receptors. AB - Ketamine is a noncompetitive glutamate N-methyl-D-aspartic acid receptor antagonist. When acutely administered to rodents, it produces a rapid antidepressant effect. There is evidence that N-methyl-D-aspartic acid receptor blockade enhances glutamatergic transmission preferentially engaging alpha-amino 3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors leading to mTOR (mammalian target of rapamycin) pathways activation, thus resulting into downstream neuroadaptive changes in limbic structures. Recent in-vitro data on primary neuronal cultures showed that ketamine activates mTOR also in dopaminergic neurons, and this activation depends on the presence of functional dopamine D3 receptors. The aim of this work was to study the in-vivo relevance of viable D3 receptors in mediating the effects of acute ketamine administration on the mTOR downstream substrate p70 ribosomal S6 kinase (p70S6K), an obligatory substrate for mTOR. We compared the effects of single ketamine 5 mg/kg, 10 mg/kg, or vehicle injection in wild-type and D3 receptor knockout mice. Animals were killed after 60 min, and their brains were processed for p-p70S6K immunohistochemistry. Ketamine increased p70S6K phosphorylation in prefrontal cortex, nucleus accumbens core and shell, ventral tegmental area, substantia nigra, hippocampal CA1, CA2, and CA3, and basolateral amygdala of wild-type mice but not in mutant mice. Our study demonstrates that ketamine-induced p70S6K phosphorylation is dependent on viable D3R expressed in most of limbic structures. PMID- 29570501 TI - Local Anesthetic Injection Speed and Common Peroneal Nerve Block Duration: A Randomized Controlled Trial in Healthy Volunteers. AB - BACKGROUND AND OBJECTIVES: The speed of local anesthetic (LA) injections in peripheral regional anesthesia ranges from slow continuous infusions (3-12 mL/h) to rapid manual injections (>7500 mL/h). Optimizing injection speed could augment the spread of LA toward the targeted nerves and influence nerve block characteristics. The objective of this study was to investigate whether injection speed of a single dose of LA affects peripheral nerve block duration. METHODS: After approval from the Danish Regional Scientific Ethics Committee, we enrolled 60 healthy adult volunteers. We used an ultrasound-guided catheter-based technique to perform a common peroneal nerve block. Participants were randomized to receive 4.0 mL of ropivacaine 0.2% with 1 of 5 injection speeds: 12, 60, 300, 600, or 1800 mL/h. Investigators and participants were blinded to group assignment and intervention. Primary outcome was duration of sensory nerve block defined by insensitivity toward cold. Secondary outcomes were duration of motor nerve block, time to onset of sensory nerve block, and grades of sensory and motor nerve block.Intergroup differences were tested by one-way analysis of variance. RESULTS: We found no differences in sensory block duration between the 5 groups. Durations were median [range]: 11 [6-14], 12 [9-14], 10.5 [2-15], 11 [8 17], and 12 [9-18] hours, respectively (P = 0.294). In addition, we found no differences in secondary outcomes. CONCLUSIONS: Injection speed of LA in the range of 12 to 1800 mL/h did not affect common peroneal nerve block duration. CLINICAL TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov, identifier NCT02801799. PMID- 29570500 TI - Curcumin mitigates axonal injury and neuronal cell apoptosis through the PERK/Nrf2 signaling pathway following diffuse axonal injury. AB - Diffuse axonal injury (DAI) accounts for more than 50% of all traumatic brain injury. In response to the mechanical damage associated with DAI, the abnormal proteins produced in the neurons and axons, namely, beta-APP and p-tau, induce endoplasmic reticulum (ER) stress. Curcumin, a major component extracted from the rhizome of Curcuma longa, has shown potent anti-inflammatory, antioxidant, anti infection, and antitumor activity in previous studies. Moreover, curcumin is an activator of nuclear factor-erythroid 2-related factor 2 (Nrf2) and promotes its nuclear translocation. In this study, we evaluated the therapeutic potential of curcumin for the treatment of DAI and investigated the mechanisms underlying the protective effects of curcumin against neural cell death and axonal injury after DAI. Rats subjected to a model of DAI by head rotational acceleration were treated with vehicle or curcumin to evaluate the effect of curcumin on neuronal and axonal injury. We observed that curcumin (20 mg/kg intraperitoneal) administered 1 h after DAI induction alleviated the aggregation of p-tau and beta APP in neurons, reduced ER-stress-related cell apoptosis, and ameliorated neurological deficits. Further investigation showed that the protective effect of curcumin in DAI was mediated by the PERK/Nrf2 pathway. Curcumin promoted PERK phosphorylation, and then Nrf2 dissociated from Keap1 and was translocated to the nucleus, which activated ATF4, an important bZIP transcription factor that maintains intracellular homeostasis, but inhibited the CHOP, a hallmark of ER stress and ER-associated programmed cell death. In summary, we demonstrate for the first time that curcumin confers protection against abnormal proteins and neuronal apoptosis after DAI, that the process is mediated by strengthening of the unfolded protein response to overcome ER stress, and that the protective effect of curcumin against DAI is dependent on the activation of Nrf2. PMID- 29570503 TI - A Nursing Partnership to Accelerate Academic Progression. AB - Associate degree nursing faculty in a Midwestern state reported that their students were being excluded from many clinical experiences and that their graduates were not being hired in Magnet(r) or Magnet-seeking hospitals. University and community college faculty formed a partnership to promote academic progression. Barriers of residency requirements, financial aid, and accreditation were overcome. Students complete all BSN prerequisites, take ADN and BSN courses simultaneously, graduate with both degrees, and take the national licensure examination. This is a viable model allowing nursing students to remain in their home town, thus decreasing costs and increasing the number of BSN-prepared nurses in rural areas. PMID- 29570502 TI - Healthy People for the 21st Century: Understanding Use of Healthy People 2020 as a Web-Based Initiative. AB - OBJECTIVE: This study assesses how the nation's preeminent health promotion and disease prevention initiative, Healthy People, is utilized by key stakeholders. METHODS: A Web-based survey was administered to assess awareness and use of Healthy People among state, local, tribal health organizations and other key stakeholder groups. Follow-up interviews were conducted with a subset of respondents. RESULTS: Awareness and use of Healthy People have remained high among state, local, and tribal stakeholders. Healthy People 2020 is most frequently used as a data source. The Leading Health Indicators (LHIs) are an important element of the initiative, and nearly 90% of organizations that use the LHIs found them valuable. Awareness and use of other tools and resources are more limited. CONCLUSIONS: Healthy People continues to be a valued resource among public health stakeholders; however, continued outreach is needed to promote the use of tools and resources available on healthypeople.gov for this decade and beyond. Healthy People is a national initiative used most frequently as a data source by state and local health departments, tribal organizations, and other public health practitioners.

PMID- 29570504 TI - Effects of Cytochrome P450 (CYP) 2C19 Genotypes on Steady-State Plasma Concentrations of Escitalopram and its Desmethyl Metabolite in Japanese Patients With Depression. AB - BACKGROUND: Plasma concentrations of the S-enantiomer of citalopram were different between extensive and poor CYP2C19 metabolizers in healthy subjects and depressed patients. However, most studies applied dose-corrected concentrations. Thus, we studied the effects of polymorphisms of the CYP2C19 gene on raw plasma drug concentrations in Japanese patients with depression. METHODS: Subjects in this study consisted of 412 depressed patients receiving 5, 10, 15, or 20 mg of escitalopram once a day. Plasma concentrations of escitalopram and desmethylescitalopram were quantified using HPLC. CYP2C19 genotypes were identified using polymerase chain reaction methods. RESULTS: There were no differences in the steady-state plasma concentrations of escitalopram or desmethylescitalopram in each dose group (5, 10, 15, or 20 mg of escitalopram) among CYP2C19 genotype groups. However, 1-way analysis of variance showed significant effects of CYP2C19 genotypes on the dose-adjusted plasma concentration of escitalopram but not in the dose-adjusted plasma concentration of desmethylescitalopram. Analysis of covariance including age, sex, and body weight showed significant effects of CYP2C19 genotypes on the dose-adjusted plasma concentration of escitalopram and the ratio of desmethylescitalopram to escitalopram. CONCLUSIONS: These findings suggest that the CYP2C19 variants are associated with steady-state plasma concentrations of escitalopram to some extent but are not associated with desmethylescitalopram. PMID- 29570507 TI - How central is central poststroke pain? The role of afferent input in poststroke neuropathic pain: a prospective, open-label pilot study. AB - Central poststroke pain (CPSP) is a neuropathic pain disorder, the underlying mechanisms of which are not well understood. It has been suggested that stroke associated loss of inhibitory neurons in the spinothalamic tract causes disinhibition of thalamic neurons, which autonomously generate ectopic nociceptive action potentials responsible for the pain experience. We hypothesized that CPSP is a result of misinterpretation of afferent sensory input by the sensitized neurons within the brain, rather than generated spontaneously by the damaged central nervous system (CNS) neurons. To test this hypothesis, we prospectively recruited 8 patients with definite CPSP affecting at least 1 extremity. In an open-label intervention, an ultrasound-guided peripheral nerve block with lidocaine was performed to block afferent sensory input from a painful extremity. Spontaneous and evoked pain, neuropathic pain descriptors, and lidocaine plasma concentrations were measured. The blockade of peripheral sensory input resulted in complete abolition of pain in 7 of the 8 subjects within 30 minutes (the primary outcome measure of the study), and >50% pain relief in the remaining participant. Median (interquartile range) spontaneous pain intensity changed from 6.5 (4.3-7.0) at baseline to 0 (0-0) after the block (P = 0.008). All mechanical/thermal hypersensitivity was abolished by the nerve block. The results suggest that it is unlikely that CPSP is autonomously generated within the CNS. Rather, this pain is dependent on afferent input from the painful region in the periphery, and may be mediated by misinterpretation of peripheral sensory input by sensitized neurons in the CNS.

PMID- 29570509 TI - Impact of obstructive sleep apnea on cardiac organ damage in patients with acute ischemic stroke. AB - BACKGROUND AND PURPOSE: Both obstructive sleep apnea (OSA) and cardiac organ damage have a crucial role in acute ischemic stroke. Our aim is to explore the relationship between OSA and cardiac organ damage in acute stroke patients. METHODS: A total of 130 consecutive patients with acute ischemic stroke were enrolled. Patients underwent full multichannel 24-h polysomnography for evaluation of OSA and echocardiography to evaluate left ventricle (LV) mass index (LV mass/BSA, LV mass/height), thickness of interventricular septum (IVS) and posterior wall (LVPW), LV ejection fraction and left atrium enlargement. Information on occurrence of arterial hypertension and its treatment before stroke was obtained from patients' history. RESULTS: 61.9% (70) of patients, mostly men (67.1%), with acute stroke had OSA (AHI > 10). Patients with acute stroke and OSA showed a significant increase (P < 0.05) of LV mass index, IVS and LVPW thickness and a significant left atrial enlargement as compared with patients without OSA. LV ejection fraction was not significantly different in stroke patients with and without OSA and was within normal limits. No relationship was found among cardiac alterations, occurrence of OSA and history of hypertension. CONCLUSION: Acute stroke patients with OSA had higher LV mass and showed greater left atrial enlargement than patients without OSA. This study confirms the high prevalence of OSA in stroke patients, suggesting also an association between OSA and cardiac target organ damage. Our finding of structural LV abnormalities in acute stroke patients with OSA suggests a potential role of OSA as contributing factor in determining both cerebrovascular and cardiac damage, even in absence of clear link with a history of blood pressure elevation.

AB - OBJECTIVE: We examined the effects of treatment with soluble epoxide hydrolase inhibitor (sEHi) and epoxyeicosatrienoic acids (EETs) analogue (EET-A), given alone or combined, on blood pressure (BP) and ischemia/reperfusion myocardial injury in rats with angiotensin II (ANG II)-dependent hypertension. METHODS: Ren 2 transgenic rats (TGR) were used as a model of ANG II-dependent hypertension and Hannover Sprague-Dawley rats served as controls. Rats were treated for 14 days with sEHi or EET-A and BP was measured by radiotelemetry. Albuminuria, cardiac hypertrophy and concentrations of ANG II and EETs were determined. Separate groups were subjected to acute myocardial ischemia/reperfusion injury and the infarct size and ventricular arrhythmias were determined. RESULTS: Treatment of TGR with sEHi and EET-A, given alone or combined, decreased BP to a similar degree, reduced albuminuria and cardiac hypertrophy to similar extent; only treatment regimens including sEHi increased myocardial and renal tissue concentrations of EETs. sEHi and EET-A, given alone or combined, suppressed kidney ANG II levels in TGR. Remarkably, infarct size did not significantly differ between TGR and Hannover Sprague-Dawley rats, but the incidence of ischemia-induced ventricular fibrillations was higher in TGR. Application of sEHi and EET-A given alone and combined sEHi and EET-A treatment were all equally effective in reducing life-threatening ventricular fibrillation in TGR. CONCLUSION: The findings indicate that chronic treatment with either sEHi or EET A exerts distinct antihypertensive and antiarrhythmic actions in our ANG II dependent model of hypertension whereas combined administration of sEHi and EET-A does not provide additive antihypertensive or cardioprotective effects. PMID- 29570512 TI - Effect of effervescent paracetamol on blood pressure: a crossover randomized clinical trial. AB - OBJECTIVE: To evaluate the effect of effervescent paracetamol on office and ambulatory blood pressure (BP) compared with noneffervescent paracetamol in hypertensive patients. DESIGN: This was a multicenter open crossover randomized clinical trial. SETTING: Primary care centers in Catalonia and the Basque Country. PARTICIPANTS: Inclusion criteria were office BP 150/95 mmHg or less and daytime ambulatory BP 140/90 mmHg or less, stable pharmacologic or nonpharmacologic antihypertensive treatment, and concomitant chronic osteoarticular pain. INTERVENTIONS: Baseline randomized assignment to 3-week periods of effervescent paracetamol (1 g three times a day) first and noneffervescent paracetamol later, or inversely, during a 7-week study period. At the start and end of each treatment period, 24-h ambulatory BP monitoring was performed. MAIN OUTCOME MEASURES: Differences in 24-h SBP between baseline and end of both treatment periods. The main analyses were performed according to the intention-to-treat principle. RESULTS: In intention-to-treat analysis, 46 patients were analyzed, 21 were treated with paracetamol effervescent and noneffervescent later, and 25 followed the opposite sequence. The difference in 24-h SBP between the two treatments was 3.99 mmHg (95% confidence interval 1.35 6.63; P = 0.004), higher in the effervescent paracetamol treatment period. Similarly, the per-protocol analysis showed a difference in 24-h SBP between the two groups of 5.04 mmHg (95% confidence interval 1.80-8.28; P = 0.004), higher in the effervescent paracetamol treatment period. Self-reported pain levels did not differ between groups and did not vary by treatment period. No serious adverse events were reported in either study arm. CONCLUSION: Effervescent paracetamol tablets are responsible for a significant daytime and overall increase in ambulatory 24-h SBP. TRIAL REGISTRATION: NCT: 02514538 EudraCT: 2010-023485-53. PMID- 29570511 TI - Whole blood omega-3 fatty acid concentrations are inversely associated with blood pressure in young, healthy adults. AB - BACKGROUND: Omega-3 fatty acids (n - 3 FA) may have blood pressure (BP)-lowering effects in untreated hypertensive and elderly patients. The effect of n - 3 FA on BP in young, healthy adults remains unknown. The Omega-3 Index reliably reflects an individuals' omega-3 status. We hypothesized that the Omega-3 Index is inversely associated with BP levels in young healthy adults. METHODS: The current study (n = 2036) is a cross-sectional study investigating the baseline characteristics of a cohort, which includes healthy adults, age 25-41 years. Individuals with cardiovascular disease, known diabetes or a BMI higher than 35 kg/m were excluded. The Omega-3 Index was determined in whole blood using gas chromatography. Association with office and 24-h BP was assessed using multivariable linear regression models adjusted for potential confounders. RESULTS: Median Omega-3 Index was 4.58% (interquartile range 4.08; 5.25). Compared with individuals in the lowest Omega-3 Index quartile, individuals in the highest had a SBP and DBP that was 4 and 2 mmHg lower, respectively (P < 0.01). A significant linear inverse relationship of the Omega-3 Index with 24-h and office BP was observed. Per 1-U increase in log-transformed Omega-3 Index the lowering in BP (given as multivariable adjusted beta coefficients; 95% confidence interval) was -2.67 mmHg (-4.83; -0.51; P = 0.02) and -2.30 mmHg (-3.92; -0.68; P = 0.005) for 24-h SBP and DBP, respectively. CONCLUSION: A higher Omega-3 Index is associated with statistically significant, clinically relevant lower SBP and DBP levels in normotensive young and healthy individuals. Diets rich in n - 3 FA may be a strategy for primary prevention of hypertension. PMID- 29570513 TI - Three-dimensional echocardiographic ventricular mass/end-diastolic volume ratio in native hypertensive patients: relation between stroke volume and geometry. AB - BACKGROUND: Elevated left ventricular (LV) mass/end-diastolic volume ratio (LVM/EDV) has been associated with higher evidence of myocardial fibrosis and dysfunction in hypertensive patients by cardiac magnetic resonance, a technique with limited availability. OBJECTIVES: We investigated the ability of three dimensional (3D) echocardiography in identifying a phenotype of LV concentric geometry according to LVM/EDV ratio, possibly detecting early myocardial damage in native-hypertensive patients. METHODS: One hundred and twenty-eight native hypertensive patients underwent 2D and 3D-echocardiography. The population was divided into two groups, according to cut-off point values of 3D-LVM/EDV ratio corresponding to its upper 95% confidence interval in a population of 90 healthy normotensive individuals: LVM/EDV ratio cut-off was 1.22 in men and 1.23 in women. RESULTS: An increased 3D-LVM/EDV ratio identified a higher rate of LV concentric geometry in comparison with 2D-derived relative wall thickness (37 versus 24%, P = 0.03). Patients with LVM/EDV ratio of 1.22 or more in men and 1.23 or more in women were significantly older, had smaller 3D-LV end-diastolic and end-systolic volumes and higher LV mass index, without difference in ejection fraction. 3D-stroke volume (P < 0.0001) was lower in patients with elevated LVM/EDV ratio. By a multilinear regression analysis, after adjusting for sex, age, heart rate, mean blood pressure and BMI, stroke volume was independently and negatively associated to LVM/EDV ratio (beta = -0.55, P < 0.0001). CONCLUSION: In native hypertensive patients, 3D-echo-derived LVM/EDV ratio identifies a higher prevalence of LV concentric geometry than 2D-relative wall thickness. Stroke volume is independently and negatively associated with LVM/EDV ratio and its reduction represents an early marker of myocardial dysfunction in hypertensives with LV concentric geometry. PMID- 29570514 TI - Isolated systolic hypertension in the young: a position paper endorsed by the European Society of Hypertension. AB - : Whether isolated systolic hypertension in the young (ISHY) implies a worse outcome and needs antihypertensive treatment is still a matter for dispute. ISHY is thought to have different mechanisms than systolic hypertension in the elderly. However, findings from previous studies have provided inconsistent results. From the analysis of the literature, two main lines of research and conceptualization have emerged. Simultaneous assessment of peripheral and central blood pressure led to the identification of a condition called pseudo or spurious hypertension, which was considered an innocent condition. However, an increase in pulse wave velocity has been found by some authors in about 20% of the individuals with ISHY. In addition, obesity and metabolic disturbances have often been documented to be associated with ISHY both in children and young adults. The first aspect to consider whenever evaluating a person with ISHY is the possible presence of white-coat hypertension, which has been frequently found in this condition. In addition, assessment of central blood pressure is useful for identifying ISHY patients whose central blood pressure is normal. ISHY is infrequently mentioned in the guidelines on diagnosis and treatment of hypertension. According to the 2013 European Guidelines on the management of hypertension, people with ISHY should be followed carefully, modifying risk factors by lifestyle changes and avoiding antihypertensive drugs. Only future clinical trials will elucidate if a benefit can be achieved with pharmacological treatment in some subgroups of ISHY patients with associated risk factors and/or high central blood pressure. PMID- 29570515 TI - Patient-Reported Quality of Life in the Highest Functioning Patients With Treacher Collins Syndrome. AB - BACKGROUND: Treacher Collins syndrome has a wide variation of clinical presentation, including airway obstruction and hearing loss. The objective of this study was to assess patient-rated quality of life in Treacher Collins syndrome, who received multidisciplinary treatment at a specialized craniofacial hospital, and to compare their quality of life with a control sample. METHODS: Treacher Collins patients under treatment in a multidisciplinary setting were assessed with the World Health Organization Quality of Life (WHOQOL-100) questionnaire. The Siviero scale was used to classify quality of life as unsatisfactory (scores below 25), intermediate (scores between 25 and 75), and satisfactory (scores above 75). Quality of life comparison between Treacher Collins patients and 2342 unaffected individuals from a previous database was performed using the analysis of variance test. Differences were considered significant at P < 0.05. RESULTS: Treacher Collins patients demonstrated an overall intermediate and satisfactory (score >60%) quality of life in almost all WHOQOL-100 facets and domains. The comparison of the scores between unaffected individuals and Treacher Collins patients demonstrated a significant difference (P < 0.05) in the environment domain. CONCLUSION: The highest functioning Treacher Collins syndrome patients under multidisciplinary treatment presented intermediate and satisfactory quality of life, consistent with quality of life scores of unaffected controls. In the environment domain, Treacher Collins patients presented even higher scores of quality of life than the control group. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29570516 TI - Did Anton Raphael Mengs Suffer From a Vascular Malformation? PMID- 29570518 TI - Surgical Treatment of Nonsyndromic Unicoronal Craniosynostosis. AB - PURPOSE: Unicoronal synostosis (UCS) remains one of the most difficult craniofacial conditions to treat. This review attempts to consolidate all existing literature from the past 25 years that has investigated surgical treatment of nonsyndromic UCS. Additional attention is paid to specific areas of controversy regarding surgical management and evaluation of UCS: outcomes of fronto-orbital advancement (FOA) versus endoscopic strip craniectomy (ESC), emergence of spring-associated cranioplasty for craniosynostosis, and morphologic assessment metrics. METHODS: A literature search from 1992 to 2017 was performed with a defined search strategy and manual screening process. About 24 studies were included in the final review. RESULTS: There is inconsistency among studies in measuring outcomes. Despite wide utilization, FOA produces mixed results, especially when looking at long-term outcomes. Preliminary data suggest advantages to using ESC over FOA with regard to facial symmetry, postoperative strabismus, and operating time. Distraction osteogenesis has long been utilized in Asia and is now being actively studied in the United States. Data on spring assisted cranioplasty are lacking. Long-term results at skeletal maturity for many of these techniques are lacking. DISCUSSION: Despite some promising results, methods of measurement are inconsistent and long-term data are lacking. All future research in this area would benefit from consistent and standardized reporting of data, including perioperative statistics and reproducible 3 dimensional computed tomography craniofacial measurements. Additionally, no definitive recommendations can be made until data at skeletal maturity are studied, and all studies would benefit from long-term follow-up data. PMID- 29570517 TI - Percutaneous Screws and External Fixation in Frontal Sinus Anterior Wall Fractures. AB - Fractures of the frontal sinus are frequently encountered injuries of maxillofacial fractures. The most common causes are traffic accidents, followed by sports-related injuries. There is still no consensus regarding the optimal management of frontal sinus fractures. The authors report a patient with depressed anterior wall fracture of the frontal sinus and superior orbital rim fracture. Reduction was performed by traction from 2 screws applied percutaneously to the depressed fragments and external fixation with an aluminum nasal splint. This technique is both minimally invasive and permits easy fixation in suitable patients. PMID- 29570519 TI - Cystic Progression of a Cavernous Malformation at the Level of the Trigeminal Root Entry Zone Presenting With Sudden Onset of Trigeminal Neuralgia. AB - BACKGROUND: Cavernous malformations (CM) in the cerebellopontine angle (CPA) are rare, and most of them are solid and extend from the internal auditory canal into the CPA. In contrast, cystic CM arising in the CPA and not involving the internal auditory canal and dura of the skull base are extremely rare. The authors present an uncommon large cystic progression of a cavernous malformation at the level of the trigeminal root entry zone evolving to severe trigeminal neuralgia and brainstem compression. METHODS: A 62-year-old female presented a sudden onset of left trigeminal neuralgia, caused by a large cystic lesion at the level of the root entry zone of the left 5th nerve. On neurological examination, she showed slight gait ataxia and hypoesthesia on the left hemiface (on the first and second trigeminal branches). Other cranial nerves were in order. Magnetic resonance imaging showed a large cystic intracranial mass, with a small solid portion, leading to brainstem compression. RESULTS: Microsurgical removal of the lesion was performed via retrosigmoid approach, with intraoperative monitoring of somato sensory evoked potentials, facial, and cochlear nerves. The posterior-medial portion of the lesion was solid, whereas the main portion was cystic, containing xanthochromic fluid. The small solid lesion continued with a thin capsule of a large cyst adherent to brainstem, cerebellar hemisphere, and trigeminal nerve entry zone. A big draining vein arising from the solid part of the lesion runned parallel to brainstem. The mass was piecemeal totally removed.After surgery the patient recovered both left trigeminal neuralgia and hypoesthesia; ataxia was significantly relieved too. Postoperative magnetic resonance imaging confirmed the total removal. Histopathological features were consistent with a CM. At 6 month follow-up, patient's symptoms at the presentation had resolved. CONCLUSION: The authors present a very rare patient of large cystic cavernous malformation at the level of the trigeminal root entry zone presenting with sudden onset of trigeminal neuralgia. Even if it has not established imaging features, a cystic cavernoma of the cerebello-pontine angle may be suspected when a cystic mass is present, not involving the internal acoustic meatus nor the skull base dura mater. Careful microneurosurgical technique and monitoring of cranial nerves allow good long-term results.

PMID- 29570521 TI - Evaluation of Fibrin Clot Attachment on Titanium Laser-Conditioned Surface Using Scanning Electron Microscopy. AB - OBJECTIVES: The study aimed to evaluate the effects of different titanium surface treatments on blood clot extension (bce). METHODS: A total of 54 titanium disks with machined surface (M), laser-conditioned surface (L), and grit-blasted surface (S) were used in the present study. The surface characteristics such as contact angles and the microroughness were determined on each group (n = 4). To evaluate the bce, 0.1 mL of human blood was dropped onto the surface of each specimen and left for 7 minutes at room temperature. After fixation, dehydration, and gold sputtering treatments, the specimens were observed under scanning electron microscope. The bce values were expressed as percentage of specimen surface covered by blood clot. RESULTS: The surface roughness (Ra +/- standard deviation [SD]) was 0.75 +/- 0.02 MUm for M, 0.25 +/- 0.02 MUm for L, and 1.30 +/ 0.03 MUm for S. The contact angles measured in static conditions (WCA +/- SD) were 71 +/- 5.4 degrees for M, 107 +/- 6.6 degrees for L, and 91 +/- 7.2 degrees for S. Regarding the bce (bce +/- SD) of M samples (65.5 +/- 4.3%) was statistically lower compared with both L (83.4 +/- 5.1%) and S samples (72.4 +/- 4.7%) (P < 0.05). Meanwhile, the L group showed the higher bce value. CONCLUSION: The present results suggest that the laser-conditioned surface may increase the wettability and bce.

PMID- 29570524 TI - Treatment of an Uncommon High-Pressure Orbital Injection Injury. AB - Injection injuries occur most commonly in the hand and digits; however, there are a limited number of reports in the literature describing injection injuries involving the orbit. High-pressure orbital injection injuries pose a number of unique challenges to the treating physician, and the approach to treating these injuries remains controversial. Often times, the extent of tissue damage is not fully appreciated at presentation, which may lead to missed diagnoses or inadequate initial treatment. In this study, the authors describe a rare incidence of high-pressure orbital injection injury. A 19-year-old male presented to the emergency department after injection of his left orbit with oil-based paint. Worsening clinical symptoms and increasing intraocular pressures within the first 24 hours necessitated take back to the operating room for orbital decompression and debridement. After an initial improvement in symptoms, the patient's clinical status deteriorated again, requiring further orbital decompression and additional periorbital debridement. Two weeks after initial presentation, soft tissue reconstruction of the surgical wounds was performed with full thickness skin grafts. The patient's globe and vision were both preserved. Orbital injection injuries, though rare, are potential globe threatening injuries. Physicians should have a low threshold for intervention and patient's must be observed closely over the first 72 hours after injury. Early diagnosis, prompt debridement, and a multidisciplinary approach are keys to improving patient outcomes. PMID- 29570525 TI - Novel Application of Ultrasonic Bone Aspirator for Hump Nose. AB - OBJECTIVE: This study was conducted to introduce and evaluate the efficacy of an ultrasonic bony aspirator in rhinoplasty for hump removal. DESIGN: Retrospective study. SETTING: University medical center. PATIENTS: Twenty patients who underwent hump removal using an ultrasonic bone aspirator from October 2013 to November 2016 were enrolled in the study. MAIN OUTCOME MEASURES: Patients were followed for >3 months after surgery. External nose status and surgical results were investigated using photographs. Postoperative complications were evaluated. RESULTS: Of the 30 patients enrolled in this study, 11 were females and 19 were males. Preoperative nasal deformities of all patients were characterized as bony humps. Postoperative dorsal status was significantly improved. There were no obvious complications such as over or under correction, delayed healing, infection, soft tissue injury, or deformity of the nasal dorsum. CONCLUSION: Application of an ultrasonic bone aspirator to remove humps in rhinoplasty is easy, safe, and effective. PMID- 29570526 TI - An Unusual Case of Headache: Isolated Fungus Ball in Concha Bullosa. AB - A concha bullosa forms when the middle turbinate becomes pneumatized, which is a common anatomic variation; however, fungus ball in concha bullosa is rather rare. An otherwise healthy 52-year-old man presented to our ear, nose and throat clinic with the complaints of midfacial pressure headache and malodorous postnasal drip. Computed tomography of the paranasal sinuses demonstrated a polypoid hyperdense lesion with slight microcalcifications in the right nasal cavity, accompanied with a complicated fluid collection in the right frontoethmoideal recess seen as hypodensity in contrast to this hyperdensity. The histopathological examination reported a fungal infection. We present an extremely rare case of isolated fungal mass in the right middle concha detected in an early stage without any evidence of fungal infection of the other paranasal sinuses and discuss the importance of reevaluation of the computed tomography scans in suspicion of a fungal sinusitis. PMID- 29570527 TI - Accessory Submandibular Salivary Gland Forming a "Horseshoe" With the Main Submandibular Salivary Gland: A Unique Variation. AB - Presence of accessory submandibular salivary gland (ASSG) is an extremely rare variation. Knowledge of its relations could be very useful to oral and maxillofacial surgeons, head and neck surgeons, and radiologists. During dissection classes, an ASSG was noted between the mylohyoid and hyoglossus muscles. The main submandibular salivary gland had superficial and deep parts. The deep part was narrow and measured about 5 cm. The lingual nerve passed between the superficial and deep parts. The accessory submandibular gland was situated below and parallel to the deep part of SSG. It also measured 5 cm. The ASSG had its own duct, which joined the duct of main gland. The ASSG and the deep part of the SSG were united at the lateral border of geniohyoid muscle to give a characteristic "horseshoe" appearance. The ASSG overlapped both lingual and hypoglossal nerves. PMID- 29570528 TI - Zygomaticofacial, Zygomaticoorbital, and Zygomaticotemporal Foramina. AB - This study aimed to assess the anatomical and morphometric characteristics of the main zygomaticofacial (ZFF), zygomaticoorbital (ZOF), and zygomaticotemporal (ZTF) foramina in Brazilian dry skulls. 61, 69, and 42 skulls for ZFF, ZOF, and ZTF were evaluated by a single calibrated examiner for format, transverse and vertical diameters, and distances from the foramina to anatomical landmarks. Paired t test, Wilcoxon test, Pearson and Spearman correlations were used. Circular outline was the predominant format for ZFF and ZTF, while oval format was the most frequent for ZOF. Median distances from ZFF to frontozygomatic and zygomaticomaxillary sutures were higher on right and left sides of the skulls, respectively (P < 0.005). Mean ZOF transverse diameter was significantly higher on the right sides of the skulls and presented positive correlation between sides (P < 0.05). No differences were observed for mean vertical diameter and distance from the ZOF to the inferolateral angle of the orbit (P > 0.05). No significant difference was found for distance from the ZTF to zygomatic arch between sides (P > 0.05), although there was a positive correlation (P < 0.05). Significant differences were found when analyzing the anatomical and morphometric aspects of ZFF, ZOF, and ZTF. PMID- 29570529 TI - Surgical Treatment of Rhinosinusitis-Related Orbital Complications: Factors Affecting Irreversible Blindness. AB - If left untreated, rhinosinusitis can rarely cause a devastating complication irreversible blindness (IB). Despite new technologies in endoscopic sinus surgery and use of new broad-spectrum antibiotics, IB outcome is still a problem for surgically treated orbital complication of paranasal sinus infection (OCPSI) patients, and factors leading to IB outcome are not actually known. The aim of this study was to assess the factors leading to the IB outcome for surgically treated OCPSI patients. Results of 25 surgically treated OCPSI patients in our clinic were combined with surgically treated OCPSI patients reported through the PubMed database search from the year 2007. Patients were divided into 2 groups: IB group and recovery group. Patients having at least 1 immune status-related additional risk factor (ARF) were more common in the IB group, having an at least 1 ARF had 1.683 risk value of IB outcome (RR: 1.683, P = 0.006). IB patients had statistically significant higher mean (21.87 +/- 40.35, P = 0.005) time interval (days) (TI) between onset of ophthalmological symptoms and surgical intervention compared to recovery group patients (2.92 +/- 2.53). ROC curve analysis for an estimation of IB outcome according to the TI value demonstrated that a cut-off value of >=2.5 days had the ideal sensitivity (87.5%) and specificity (71.9%) that resulted in IB outcome. (80.5% power, P = 0.008) IB and recovery group patients did not differ according to orbital complication type according to Chandler's classification (P = 0.492) and white blood cell count status (P = 0.584). In conclusion, OCPSI patients with ARFs and delayed admission after onset of orbital symptoms have a higher risk of IB outcome. These patients deserve prompt evaluation and early surgical intervention to prevent blindness. With future studies, new surgical criteria, including the ARF status and onset of ophthalmological symptoms (>=2.5 days) may be added to classical surgical criteria to prevent IB for OCPSI cases. PMID- 29570530 TI - The "Flap Suture Anchoring" Technique for Safe Oral Floor Reconstruction With Preservation of Alveolar Process. AB - Flaps-based microsurgery is routinely applied to reconstruct oral floor defects caused by oncologic resection. To prevent orocutaneous fistulae, flaps are frequently sutured with buccal vestibule mucosa after sacrificing the alveolar process. The patients suffered denture loss and irreversible structural damage. For reliable oral floor reconstruction with preservation of alveolar process, the authors introduced the flap "suture anchoring" technique. Oral floor, hemiglossal oral floor, and tongue base-parapharyngeal wall-oral floor defects were included in this study. The flap anchoring technique involves structural oral floor reconstruction with a chimeric anterolateral thigh-free flap or radial forearm flap with adipofascial tissue extension. The dead space in oral floor is filled with vastus lateralis muscle or adipofascial tissue, then holes are drilled on the alveolar bone among tooth root, beneath the attached gingiva. Skin paddle is sutured with 4-0 sutures through the alveolar holes thus anchored to the mandible. By applying this technique, there was no wound infection or orocutaneous fistulae in all patients postoperatively, even experienced postoperative radiotherapy. In addition, a soft and natural jaw-tongue furrow could be formed to allow the free movement of tongue. Taken together, the flap anchoring technique offers a safe and reliable approach to recover oral function and preservation of occlusion.

PMID- 29570532 TI - Endoscopic Transsphenoidal Surgery for an Adult Patient With Giant Exophytic Chiasmatic/Hypothalamic Glioma. AB - Optic pathway hypothalamic gliomas are intrinsic low-grade gliomas involving the optic nerve, chiasm, optic tract, and hypothalamus. The rarity of these tumors and their unpredictable course make assessment and standardization of treatment modalities difficult. Tumor debulking via various transcranial approaches was considered to be effective at controlling tumor growth, but with high rates of severe surgery-related complications. In the present case, endoscopic transsphenoidal surgery was initiated to debulk the exophytic chiasmatic/hypothalamic glioma with good preservation of hypothalamic and endocrine functions. The authors suggest transsphenoidal surgery with tumor debulking could be an effective and safe treatment for patients with chiasmatic/hypothalamic gliomas. PMID- 29570533 TI - Subunit Reconstruction of Mid-Facial Defects With Free Style Facial Perforator Flaps. AB - INTRODUCTION: Reconstruction of facial defects is not only important for cosmesis but also for the function. Local flaps are considered the best reconstruction method for facial defects. The authors want to show the feasibility of free style facial perforator flap for the reconstruction of moderate sized mid-facial defects. METHODS: Free style facial artery and lateral nasal artery perforator flaps were performed in 22 patients (11 males and 11 females) who had removal of facial tumor between March 2015 and December 2016 RESULTS:: The median age of patients was 62 years (range: 35-84). The mean follow-up period was 12.6 months (range: 5-24). Pathology results were basal cell carcinoma in 13 patients, squamous cell carcinoma in 6 patients, and other skin tumors in 3 patients. The defect size ranged from 2 * 2 to 5 * 5 cm. No major or minor complication happened but 1 flap had venous congestion that healed without any intervention CONCLUSION:: Free style facial perforator flaps are highly reliable flaps with wide range of motion. In addition, they provide single-stage closure with esthetic subunit reconstruction. With the current knowledge of reconstruction and skills of microsurgery, they can be easily the first choice for the closure of mid-facial defects. PMID- 29570534 TI - Neuromuscular Adaptations to Work-matched Maximal Eccentric versus Concentric Training. AB - : It is unclear whether the superiority of eccentric over concentric training on neuromuscular improvements is due to higher torque (mechanical loading) achievable during eccentric contractions or due to resulting greater total work. PURPOSE: This study aimed to examine neuromuscular adaptations after maximal eccentric versus concentric training matched for total work. METHODS: Twelve males conducted single-joint isokinetic (180 degrees .s) maximal eccentric contractions of the knee extensors in one leg (ECC-leg) and concentric in the other (CON-leg), 6 sets per session (3-5 sets in the initial 1-3 sessions), 2 sessions per week for 10 wk. The preceding leg performed 10 repetitions per set. The following leg conducted the equivalent volume of work. In addition to peak torque during training, agonist EMG and MRI-based anatomical cross-sectional area (ACSA) and transverse relaxation time (T2) at midthigh as reflective of neural drive, hypertrophy, and edema, respectively, were assessed weekly throughout the training period and pre- and posttraining. Whole muscle volume was also measured pre- and posttraining. RESULTS: Torque and EMG (in trained contraction conditions) significantly increased in both legs after week 1 (W1) and week 4 (W4), respectively, with a greater degree for ECC-leg (torque +76%, EMG +73%: posttraining) than CON-leg (+28%, +20%). ACSA significantly increased after W4 in ECC-leg only (+4%: posttraining), without T2 changes throughout. Muscle volume also increased in ECC-leg only (+4%). Multiple regression analysis revealed that changes (%Delta) in EMG solely explained 53%-80% and 30%-56% of the total variance in %Deltatorque through training in ECC-leg and CON-leg, respectively, with small contributions (+13%-18%) of %DeltaACSA for both legs. CONCLUSION: Eccentric training induces greater neuromuscular changes than concentric training even when matched for total work, whereas most of the strength gains during 10-wk training are attributable to the increased neural drive. PMID- 29570535 TI - Overview of the NASA 70-day Bed Rest Study. AB - PURPOSE: The purpose of this article was to provide an overview of the National Aeronautics and Space Administration (NASA) 70-day Bed Rest Study. The integrated complement of investigations and the standardized bed rest environment that served as the platform for this study complement are described. Outcomes of the studies will not be presented here but will be reported in separate publications. METHODS: A set of studies running in an integrated fashion along the entire period (pre-, in-, and post-bed rest) and using the same subjects is referred in this article as "the campaign" or "complement." NASA selected eight individual studies to participate in the 70-d bed rest campaign. These studies were integrated to increase efficiency in the utilization of resources and to share common measures among the investigations. In addition to the individual studies addressing specific aims, a battery of standardized measures was included. Standard measures target a wide range of physiologic systems and represent some of the testing routinely done on astronauts. Bed rest subjects underwent rigorous medical and psychological screening. Standardized conditions included 70 d of bed rest in a 6 degrees head-down tilt position. Subjects' vital signs, body weight, and fluid intake and output were measured daily. A standardized diet was provided to ensure consistent nutritional intake across subjects. Exercising subjects were prescribed individualized aerobic and resistance training 6 d.wk performed in a horizontal body position. Subjects in the testosterone supplementation countermeasure group received testosterone enanthate injections at 2-wk intervals during bed rest. CONCLUSION: Long-duration head-down tilt bed rest provided a suitable platform for examining physiologic effects of spaceflight and testing countermeasures in a ground-based model. Integrating studies into a complement is an effective way to support multiple investigations while minimizing the number of subjects to answer many research questions. PMID- 29570537 TI - Myocellular Responses to Concurrent Flywheel Training during 70 Days of Bed Rest. AB - PURPOSE: This investigation evaluated myocellular responses to an integrated resistance and aerobic training program during 70 d of bed rest. METHODS: Training was 6 d.wk on a small-footprint gravity-independent flywheel resistance and aerobic device; 3 d of maximal flywheel supine quadriceps and calf exercises with continuous rowing separated by 4 to 6 h, and 3 d of interval rowing. Vastus lateralis (VL) and soleus (SOL) muscle biopsies were obtained from eight healthy males (age, 28 +/- 4 yr; BMI, 25 +/- 3 kg.m; VO2max, 42 +/- 6 mL.kg.min) before and after 6 degrees head-down tilt bed rest. Vastus lateralis and SOL myosin heavy chain (MHC) I and IIa single muscle fiber size and functional characteristics, as well as overall fiber type distribution, capillarization, and metabolic enzyme activities were evaluated. RESULTS: In the VL, MHC I size and power (absolute and normalized) were preserved. The MHC IIa fibers hypertrophied (+6%, P < 0.05) without a change in absolute power, so normalized power declined (-7%, P < 0.05). In the SOL, MHC I fibers atrophied (-9%) and absolute power declined (-17%) (P < 0.05), whereas normalized power was maintained. Size, absolute power, and normalized power were protected in the less-abundant MHC IIa fibers. Reduced MHC coexpressing hybrid fibers, generally indicative of an exercise training effect, was apparent in the VL, whereas fiber type was maintained in the SOL. Capillarization and metabolic enzymes were generally preserved or increased in VL and SOL. CONCLUSIONS: The integrated resistance and aerobic training protocol on a device maintains several key myocellular characteristics during prolonged unloading, but further refinement of the exercise approach to fully protect the SOL is warranted. PMID- 29570538 TI - Acute Effect of Noradrenergic Modulation on Motor Output Adjustment in Men. AB - PURPOSE: To determine the role of noradrenergic modulation in the control of motor output, we compared the acute effect of reboxetine (REB), a noradrenaline reuptake inhibitor, to a placebo (PLA) on knee extensors motor performance and cortical and spinal excitability. METHODS: Eleven young men took part in two randomized experiments during which they received either 8 mg of REB or a PLA. The torque produced during a maximal voluntary contraction (MVC) and its variability (i.e., coefficient of variation) during submaximal contractions ranging from 5% to 50% MVC were measured. Paired electrical (PES) and transcranial magnetic stimulation (TMS) were used to assess changes in voluntary activation during MVC, and corticospinal (motor-evoked potential (MEP)) and spinal excitability (Hoffmann (H) reflex) during contraction at 20% MVC. RESULTS: MVC torque and torque steadiness increased respectively by 9.5% and 24% on average in REB compared with PLA condition (P < 0.001). Voluntary activation tested by TMS and PES was greater (~3%; P < 0.05) in REB than PLA condition. The increase in voluntary activation in REB condition was significantly correlated with subjects' initial voluntary activation level when tested by TMS (r = -0.62; P = 0.048) and PES (r = -0.86; P < 0.01). The maximal amplitudes of H reflex and MEP and the slope of their recruitment curves were enhanced by REB (P < 0.05). The ratio between the TMS-induced EMG silent period and the corresponding MEP (silent period/MEP) was reduced in REB condition (P < 0.01). CONCLUSIONS: The present findings indicate that voluntary activation and accuracy in force control can be increased by an enhanced level of noradrenaline concentration. This improvement in motor performance is accompanied by changes located at both cortical and spinal levels. PMID- 29570536 TI - Efficacy of Exercise and Testosterone to Mitigate Atrophic Cardiovascular Remodeling. AB - PURPOSE: Early and consistent evaluation of cardiac morphology and function throughout an atrophic stimulus is critically important for the design and optimization of interventions. This randomized controlled trial was designed 1) to characterize the time course of unloading-induced morphofunctional remodeling and 2) to examine the effects of exercise with and without low-dose testosterone supplementation on cardiac biomarker, structural, and functional parameters during unloading. METHODS: Twenty-six subjects completed 70 d of head-down tilt bed rest (BR): 9 were randomized to exercise training (Ex), 8 to EX and low-dose testosterone (ExT), and 9 remained sedentary (CONT). Exercise consisted of high intensity, continuous, and resistance exercise. Cardiac morphology (left ventricular mass [LVM]) and mechanics (longitudinal, radial, and circumferential strain and twist), cardiovascular biomarkers, and cardiorespiratory fitness (VO2peak) were assessed before, during, and after BR. RESULTS: Sedentary BR resulted in a progressive decline in LVM, longitudinal, radial, and circumferential strain in CONT, whereas Ex and ExT mitigated decreases in LVM and function. Twist was increased throughout BR in sedentary BR, whereas after an initial increase at BR7, there were no further changes in twist in Ex and ExT. HDL cholesterol was significantly decreased in all groups compared with pre-BR (P < 0.007). There were no significant changes in other cardiovascular biomarkers. Change in twist was significantly related to change in VO2max (R = 0.68, P < 0.01). CONCLUSION: An integrated approach with evaluation of cardiac morphology, mechanics, VO2peak, and biomarkers provides extensive phenotyping of cardiovascular atrophic remodeling. Exercise training and exercise training with low-dose testosterone supplementation abrogates atrophic remodeling. PMID- 29570539 TI - Comparison between Slow Components of HR and VO2 Kinetics: Functional Significance. AB - PURPOSE: Aerobic exercise prescription is often based on a linear relationship between pulmonary oxygen consumption (VO2) and heart rate (HR). The aim of the present study was to test the hypothesis that during constant work rate (CWR) exercises at different intensities, the slow component of HR kinetics occurs at lower work rate and is more pronounced that the slow component of VO2 kinetics. METHODS: Seventeen male (age, 27 +/- 4 yr) subjects performed on a cycle ergometer an incremental exercise to voluntary exhaustion and several CWR exercises: 1) moderate CWR exercises, below gas exchange threshold (GET); 2) heavy CWR exercise, at 45% of the difference between GET and VO2 peak (Delta); 3) severe CWR exercise, at 95% of Delta; 4) "HRCLAMPED" exercise in which work rate was continuously adjusted to maintain a constant HR, slightly higher than that determined at GET. Breath-by-breath VO2, HR, and other variables were determined. RESULTS: In moderate CWR exercises, no slow component of VO2 kinetics was observed, whereas a slow component with a relative amplitude (with respect to the total response) of 24.8 +/- 11.0% was observed for HR kinetics. During heavy CWR exercise, the relative amplitude of the HR slow component was more pronounced than that for VO2 (31.6 +/- 11.2% and 23.3 +/- 9.0%, respectively). During HRCLAMPED, the decrease in work rate (~14%) needed to maintain a constant HR was associated with a decreased VO2 (~10%). CONCLUSIONS: The HR slow component occurred at a lower work rate and was more pronounced than the VO2 slow component. Exercise prescriptions at specific HR values, when carried out for periods longer than a few minutes, could lead to premature fatigue. PMID- 29570541 TI - Your Next Professional Step ... Becoming an Author. PMID- 29570540 TI - Discovering the Tiny Warrior Within. PMID- 29570542 TI - Caring for the Orthopaedic Patient With a History of Bariatric Surgery. AB - Bariatric surgery is performed on the gastrointestinal tract as a solution to obesity, and prevalence of these surgical procedures continues to rise. Bariatric surgery creates restrictive and/or malabsorptive properties, causing nutritional deficits from the physiological changes in absorption and a hypoacidic environment. Although surgery induces sustained weight loss, decreases mortality, and provides resolution or improvement to comorbidities of obesity, it can also come with complications. Common long-term complications of bariatric surgery include malnutrition, anemia, impaired wound healing, and impaired bone health. It is essential that nurses and the healthcare team caring for orthopaedic individuals with a history of bariatric surgery be aware of the special needs of these individuals, especially in the promotion of bone health. Using a multidisciplinary approach for the advancement of the orthopaedic patient's health will help promote quality patient care.

PMID- 29570544 TI - Developing and Testing an International Audit of Nursing Quality Indicators for Older Adults With Fragility Hip Fracture. AB - BACKGROUND: Fragility hip fracture in older adults often has poor outcomes, but these outcomes can be improved with attention to specific quality care indicators. PURPOSE: The International Collaboration of Orthopaedic Nursing (ICON) developed an audit process to identify the extent to which internationally accepted nursing quality care indicators for older adults with fragility hip fracture are reflected in policies, protocols, and processes guiding acute care. METHODS: A data abstraction tool was created for each of 12 quality indicators. Data were collected using a mixed-methods approach with unstructured rounds. A rationale document providing evidence for the quality indicators and a user evaluation form were included with the audit tool. A purposeful sample of 35 acute care hospitals representing 7 countries was selected. RESULTS: Thirty-five hospitals (100%) completed the survey. Respondents viewed the content as relevant and applicable for the defined patient population. Although timing and frequency of implementation varied among and within countries, the identified quality indicators were reflected in the majority of policies, protocols, or processes guiding care in the hospitals surveyed. CONCLUSION: Developing and testing an audit of nurse-sensitive quality indicators for older adults with fragility hip fracture demonstrate international consensus on common core best practices to ensure optimal acute care.

PMID- 29570546 TI - Impact of Music Therapy on Hospitalized Patients Post-Elective Orthopaedic Surgery: A Randomized Controlled Trial. AB - BACKGROUND: Music therapy (MT) research has demonstrated positive effects on fatigue, depressed mood, anxiety, and pain in perioperative care areas. However, there has been limited research on the effects of MT for surgical patients on orthopaedic units. PURPOSE: The purpose of this study was to understand the impact of MT sessions on post-elective orthopaedic surgery patients' pain, mood, nausea, anxiety, use of narcotics and antiemetics, and length of stay. METHODS: This was a randomized controlled study with an experimental arm (MT sessions) and a control arm (standard medical care). Patients received MT within 24 hours of admission to the unit, as well as every day of their stay. Same-day pre- and postdata were collected 30 minutes apart for both arms, including patient self reported mood, pain, anxiety, and nausea. Use of medications and length of stay were gleaned from the electronic medical record. RESULTS: Data were obtained for 163 patients, age 60.5 +/- 11.1 years, 56% of whom were male. Joints targeted by surgeries were hips (54%), knees (42%), and shoulders (4%). There were significantly greater changes favoring the MT group on Day 1 (pain, anxiety, and mood), Day 2 (pain, anxiety, mood, and nausea), and Day 3 (pain, anxiety, and mood). Among participants with a pre-pain score of 2 or more on Day 1, a decrease of at least 2 points was noted in 36% of the MT group and 10% of the control group (P < .001). Overall, 73% of MT patients versus 41% of control patients reported improved pain (P < .001). No significant between-group differences in medications or length of stay were noted. CONCLUSIONS: We observed greater same day improvements of pain, emotional status, and nausea with MT sessions, compared to usual care, in patients hospitalized after elective orthopaedic surgeries. Effects on narcotic and antiemetic usage, as well as length of stay, were not observed. More research needs to be conducted to better understand the benefits of MT pre- and post-elective orthopaedic surgery. PMID- 29570548 TI - Intrathecal Baclofen Therapy Prior to Spinal Fusion for Patients With Gross Motor Function Classification System IV-V Cerebral Palsy. AB - BACKGROUND: Patients with Gross Motor Function Classification System (GMFCS) IV-V cerebral palsy (CP) have significant spasticity and frequently develop scoliosis. Intrathecal baclofen (ITB) pumps are effective in managing spasticity. The effect of ITB therapy on the postoperative course following spinal fusion in patients with GMFCS IV-V CP has not been described. This study sought to compare postoperative recovery, including complications, in patients using ITB therapy with those with no ITB therapy. PURPOSE: Evaluate the effect of ITB on the postoperative recovery for patients with GMFCS IV-V CP who undergo spinal fusion for scoliosis. METHODS: Health records for patients with GMFCS IV-V CP who underwent a spinal fusion for scoliosis at a major quaternary-care children's hospital from January 2009 to October 2015 were reviewed and relevant data were abstracted. Descriptive statistics and regression models were used to compare patients. RESULTS: Sixty-nine patients were included-19 ITB therapy and 50 no ITB therapy. Demographic and operative characteristics were similar across groups. The mean length of stay for patients in the ITB therapy group was 11.2 days and 14.3 days for the no ITB therapy group, with no difference between groups (p = .12). Pain scores in both groups decreased at the same rate, with scores in the ITB therapy group averaging one-half point lower (p = .32). The average amount of morphine equivalents (p = .71) and benzodiazepine equivalents (p = .53) used were similar between groups. Complication rates were significantly different between groups. Four (21%) of the ITB therapy patients had 1 or more complications whereas 28 (56%, p = .01) in the no ITB therapy group had 1 or more complications. The average number of complications per patient in the ITB therapy group was 0.3 (SD: 0.075, range: 0-3) and the no ITB therapy group was 1.1 (SD: 1.1, range: 0-6, p = .01). CONCLUSIONS: There was no significant difference in length of stay, pain scores, or pain/spasticity medication use between groups after spinal fusion, but there was a significantly lower incidence of complications in the ITB therapy group. PMID- 29570549 TI - Skin Laceration in Collagenase Clostridium histolyticum Treatment for Dupuytren's Contracture. AB - BACKGROUND: Dupuytren's contracture produces a progressive flexion contracture of the affected fingers. Collagenase Clostridium histolyticum produces breakdown of the cord in the hand and/or finger(s) that tightens as a result of the disease creating a contracture, allowing manual traction and cord rupture. One of the side effects is spontaneous skin laceration when the finger is extended. OBJECTIVES: To evaluate the development of skin lacerations in Dupuytren's contracture treated with collagenase Clostridium histolyticum, to determine predisposing factors, and evaluate the effectiveness of 2 different treatments (antiseptic and non-antiseptic dressings). PARTICIPANTS: Included 157 patients diagnosed with Dupuytren's contracture and treated with collagenase Clostridium histolyticum. METHODS: Analysis of variables and logistic regression model were applied to determine their possible relationship with skin lacerations. The effectiveness of the type of treatment used was evaluated by comparing the amount of time required for healing. RESULTS: Skin lacerations were present in 33.1% (n = 52) of patients, with an average laceration length of 1.12 (SD: 0.70) cm. Characteristics that were significant predisposing factors for lacerations were disease bilateralism (p = .002), previous surgical intervention (p = .003), and initial matacarpophalangeal joint contracture (p < .001). Worse initial contracture (Z = 5.94; p < .001) had a greater risk of laceration as did those who had prior hand surgery, or whose little finger was affected. Average treatment length of healing was 11.24 days (SD: 8.13). All wounds healed successfully. There were no significant differences (p = .511) in healing between different dressings evaluated. CONCLUSIONS: Skin lacerations as a consequence of treating Dupuytren's contracture with collagenase Clostridium histolyticum occur often and are moderately serious. For all cases, evolution is satisfactory in less than 2 weeks, and the type of treatment does not appear to make any difference in healing time. PMID- 29570551 TI - Rotator Cuff Tear.

PMID- 29570554 TI - Paediatric Intestinal Pseudo-obstruction: Evidence and Consensus-based Recommendations From an ESPGHAN-Led Expert Group. AB - OBJECTIVES: Chronic intestinal pseudo-obstructive (CIPO) conditions are considered the most severe disorders of gut motility. They continue to present significant challenges in clinical care despite considerable recent progress in our understanding of pathophysiology, resulting in unacceptable levels of morbidity and mortality. Major contributors to the disappointing lack of progress in paediatric CIPO include a dearth of clarity and uniformity across all aspects of clinical care from definition and diagnosis to management. In order to assist medical care providers in identifying, evaluating, and managing children with CIPO, experts in this condition within the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition as well as selected external experts, were charged with the task of developing a uniform document of evidence- and consensus-based recommendations. METHODS: Ten clinically relevant questions addressing terminology, diagnostic, therapeutic, and prognostic topics were formulated. A systematic literature search was performed from inception to June 2017 using a number of established electronic databases as well as repositories. The approach of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was applied to evaluate outcome measures for the research questions. Levels of evidence and quality of evidence were assessed using the classification system of the Oxford Centre for Evidence-Based Medicine (diagnosis) and the GRADE system (treatment). Each of the recommendations were discussed, finalized, and voted upon using the nominal voting technique to obtain consensus. RESULTS: This evidence- and consensus-based position paper provides recommendations specifically for chronic intestinal pseudo-obstruction in infants and children. It proposes these be termed paediatric intestinal pseudo obstructive (PIPO) disorders to distinguish them from adult onset CIPO. The manuscript provides guidance on the diagnosis, evaluation, and treatment of children with PIPO in an effort to standardise the quality of clinical care and improve short- and long-term outcomes. Key recommendations include the development of specific diagnostic criteria for PIPO, red flags to alert clinicians to the diagnosis and guidance on the use of available investigative modalities. The group advocates early collaboration with expert centres where structured diagnosis and management is guided by a multi-disciplinary team, and include targeted nutritional, medical, and surgical interventions as well as transition to adult services. CONCLUSIONS: This document is intended to be used in daily practice from the time of first presentation and definitive diagnosis PIPO through to the complex management and treatment interventions such as intestinal transplantation. Significant challenges remain to be addressed through collaborative clinical and research interactions. PMID- 29570555 TI - Single Balloon-assisted Colonoscopy for Placement of Colonic Manometry Catheters: Initial Experience in Children. AB - OBJECTIVES: Colonic manometry is used frequently in children with long standing and difficult to manage constipation to aid in management decisions. Accurate analysis requires placement of the colonic manometry catheter in the colon without looping. This is technically difficult due to the long-standing nature of the constipation in most patients leading to sigmoid and other colonic redundancy. Single balloon colonoscopy has been successfully used in adult in cases of difficult colonoscopy. We report the first series of single balloon assisted colonoscopy for performing difficult colonoscopy in children and placing colonic manometry catheters. METHODS: Retrospective chart review was performed to identify patients undergoing the procedure. All patients had prior preparation with nasogastric golytely. RESULTS: Using the single balloon technique, 36 patients underwent placement of the colonic manometry catheter (ages ranging from 3 to 16 years, weights 12 to 95 kg). Catheter placement was successful in all cases with procedure times of 20 to 105 minutes. No major complications were noted. CONCLUSIONS: This is the first reported series of using single balloon assisted colonoscopy to perform difficult colonoscopy in children and place colonic manometry catheters. It may have other therapeutic implications in children such as removal of polyps or placement of similar catheters. PMID- 29570556 TI - Province-wide Biliary Atresia Home Screening Program in British Columbia: Evaluation of First 2 Years. AB - BACKGROUND AND OBJECTIVES: Biliary atresia (BA), a rare newborn liver disease, is the leading cause of liver-related death in children. Early disease recognition and timely surgical Kasai hepatoportoenterostomy (KP) offers long-term survival without liver transplant. Universal BA screening in Taiwan using infant stool color cards (ISCCs) has proven effectiveness. We report our experience with infant stool color card (ISCC) BA screening in a province-wide program in British Columbia (BC). The objective of this study is to assess program performance and cost from launch April 1, 2014 to March 31, 2016. METHODS: ISCCs distributed to families upon maternity ward discharge. Parents were instructed to monitor their infant's stool color for 1 month and contacted the screening center with concerns. The number of live births, ISCC distribution, BA cases, and costs were recorded. Cases with Program screen success had both acholic stool recognition (ISCC screen success) and timely referral for BA. RESULTS: All 126 maternity units received ISCCs. Of 87,583 live births there were 6 BA cases. Of the 5 cases with ISCC Screen Success 3 had Program Screen Success. The median KP age in the program screen success and failure groups was 49 (42-52) and 116 (49-184) days, respectively. Program sensitivity was 50%, specificity 99%, positive predictive value 4%, and negative predictive value 99%. A random sample of 1054 charts at BC Children's Hospital found an ISCC distribution rate of 94%. After a phase-in period, the annual program cost was $30,033.82, and the ISCC cost per birth was $0.68. CONCLUSIONS: The screening program has high specificity and distribution with low cost. Successful program case identification had earlier age at KP. Program modifications aim to improve sensitivity. Longer-term studies will determine program impact on health outcomes. PMID- 29570557 TI - The Use and Safety of a Novel Haemostatic Spray in the Endoscopic Management of Acute Nonvariceal Upper Gastrointestinal Bleeding in Children. AB - AIMS AND BACKGROUND: Advanced endohaemostatic technique performance and experience is extremely variable in distribution amongst paediatric endoscopists. Haemostatic spray (Hemospray), a novel endohaemostatic topically applied powder has the advantage of extreme ease of use and; hence may lower the threshold of competency required by the endoscopist thereby potentially reducing mortality. The aim of the study is to prospectively evaluate the efficacy and the safety of haemostatic spray in paediatric patients with acute upper gastrointestinal bleeding (AUGIB). METHODS: Prospective enrolment of children with AUGIB (Group 1) occurred, either as primary therapy or as an adjunct to standard endohaemostatic therapeutic techniques. Patients were assessed for likely need for endohaemostatic intervention of >8 of 24 of the paediatric Sheffield AUGIB score.A follow-up endoscopy occurred in those deemed to have clinical need pre discharge. For comparison, another group (Group 2) of patients, who received conventional endohaemostatic treatment in the preceding 36 months, were reviewed. RESULTS: A total of 20 applications of Hemospray occurred in 17 patients (8 boys, median (range) age: 6.5 years (2 days to 17.75 years) and a total of 29 patients were enrolled in Group 2 (16 boys, median [range] age: 5.1 [0.25-17.0]). All patients tolerated haemostatic spray applications with no adverse events. The haemostatic spray group achieved 100% initial haemostasis with 18% rebleeding rate, although only a 6% failure rate after re-application. In the conventional group, similar 100% initial haemostasis was achieved with 24% rebleeding rate and 7% failure rate necessitating surgical interventions. CONCLUSIONS: This paediatric series suggests that monotherapy with haemostatic spray is as effective as conventional approaches in the management of AUGIB.

PMID- 29570559 TI - The Health Care Transition of Youth With Liver Disease Into the Adult Health System: Position Paper From ESPGHAN and EASL. AB - BACKGROUND: Medical advances have dramatically improved the long-term prognosis of children and adolescents with once-fatal hepatobiliary diseases. However, there is no generally accepted optimal pathway of care for the transition from paediatric care to the adult health system. AIM: The purpose of this position paper is to propose a transition process for young people with paediatric onset hepatobiliary diseases from child-centred to adult-centred healthcare services. METHODS: Seventeen ESPGHAN/EASL physicians from 13 countries (Austria, Belgium, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, Spain, Sweden, Switzerland, and United Kingdom) formulated and answered questions after examining the currently published literature on transition from childhood to adulthood. PubMed and Google Scholar were systematically searched between 1980 and January 2018. Quality of evidence was assessed by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) system. Expert opinions were used to support recommendations whenever the evidence was graded weak. All authors voted on each recommendation, using the nominal voting technique. RESULTS: We reviewed the literature regarding the optimal timing for the initiation of the transition process and the transfer of the patient to adult services, principal documents, transition multi-professional team components, main barriers, and goals of the general transition process. A transition plan based on available evidence was agreed focusing on the individual young people's readiness and on coordinated teamwork, with transition monitoring continuing until the first year of adult services.We further agreed on selected features of transitioning processes inherent to the most frequent paediatric-onset hepatobiliary diseases. The discussion highlights specific clinical issues that will probably present to adult gastrointestinal specialists and that should be considered, according to published evidence, in the long-term tracking of patients. CONCLUSIONS: Transfer of medical care of individuals with paediatric onset hepatobiliary chronic diseases to adult facilities is a complex task requiring multiple involvements of patients and both paediatric and adult care providers. PMID- 29570560 TI - Dual Sofosbuvir/Daclatasvir Therapy in Adolescent Patients With Chronic Hepatitis C Infection. AB - OBJECTIVES: Dual sofosbuvir/daclatasvir (SOF/DCV) therapy is currently recommended by the European Association for Study of Liver (EASL) as an option for the treatment of chronic hepatitis C virus (HCV) infection in adults for all genotypes; however, it is still not considered for patients younger than 18 years old. We aimed to test safety and efficacy of SOF/DCV in adolescent patients 12 to 17 years old with chronic HCV, genotype 4 infection. METHODS: We conducted a prospective, uncontrolled, open-label multicenter study. A total of 30 chronic HCV-infected adolescents, aged from 12 to 17 years old were included and treated with dual SOF/DCV for 12 weeks. Patients were monitored throughout the treatment and follow-up period for safety and efficacy outcome measures including the sustained virologic response 12 (SVR12) rate. RESULTS: The intention-to-treat (ITT) SVR12 rate was 29 of 30 (96.7%; 95% confidence interval [CI] 83.3%-99.4%). The only patient who did not achieve SVR12 was lost to follow-up after showing viral negativity at the end of treatment (EOT) visit. Whereas all the remaining 29 patients (100%, 95% CI 88.3%-100%) who completed the follow-up visits achieved SVR12. All patients showed normalized liver enzymes with normal hematological, liver and renal function tests at the end of the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study. CONCLUSIONS: SOF/DCV combined therapy could be a safe and effective treatment in adolescent patients 12 to 17 years old with chronic HCV genotype 4 infection.

PMID- 29570564 TI - Low Risk of Cervical Cancer/Precancer Among Most Women Under Surveillance Postcolposcopy. AB - OBJECTIVE: To inform impending postcolposcopy guidelines, this analysis examined the subsequent risk of CIN 3+ among women with a grade lower than CIN 2 (< CIN 2) colposcopy results, taking into account the referring results that brought them to colposcopy and cotest results postcolposcopy. METHODS: We analyzed 107,005 women from 25 to 65 years old, recommended for colposcopy at Kaiser Permanente Northern California. We estimated absolute risks of CIN 3+ among women: (1) recommended for colposcopy (precolposcopy), (2) following colposcopy and with histology results < CIN 2 (postcolposcopy), and (3) with cotest results 12 months after a < CIN 2 colposcopy (return cotest). RESULTS: After colposcopy showing < CIN 2 (n = 69,790; 87% of the women at colposcopy), the 1-year risk of CIN 3+ was 1.2%, compared with 6.3% at the time of colposcopy recommendation. Negative cotest results 1 year after colposcopy identified a large group (37.1%) of women whose risk of CIN 3+ (i.e., <0.2% at 3 years after postcolposcopy cotest) was comparable with women with normal cytology in the screening population. These risks are consistent with current guidelines recommending repeat cotesting 12 months after colposcopy < CIN 2 and a 3-year return for women with a negative postcolposcopy cotest. CONCLUSIONS: Most women are at low risk of subsequent CIN 3+ after a colposcopy showing < CIN 2, especially those who are human papillomavirus-negative postcolposcopy, consistent with current management guidelines for repeat testing intervals. Before the finalizing the upcoming guidelines, we will consider additional rounds of postcolposcopy cotesting. PMID- 29570565 TI - p16 Immunohistochemistry Is Not Always Required For Accurate Diagnosis of Grade 2 Squamous Intraepithelial Lesions. AB - OBJECTIVES: Preinvasive squamous neoplasms of the lower genital tract are currently classified using a two-tier system (high- or low-grade squamous intraepithelial lesion) as directed by the Lower Anogenital Squamous Terminology (LAST) guidelines but may also be subclassified as intraepithelial neoplasia grade 1 (-IN1), -IN2, or -IN3. The LAST recommended that all diagnoses of -IN2 be supported by immunohistochemistry (IHC) for p16. We examined whether p16 and Ki 67 IHC are necessary to diagnose -IN2 when the lesion has obvious high-grade histology. MATERIALS AND METHODS: p16 and Ki-67 IHC were performed prospectively and retrospectively on vulvar, vaginal, and cervical specimens with an initial diagnosis of -IN2 based on hematoxylin and eosin morphology, and a final diagnosis was made after consensus review. RESULTS: Five of 46 prospective and four of 38 retrospective cases were p16 negative. The diagnosis of -IN2 was maintained in eight of these nine cases because of compelling high-grade squamous intraepithelial lesion histology. Overall, p16 and Ki-67 IHC altered the -IN2 diagnosis to a lower grade in only one of 84 cases (1.2%, <0.01%-7.1%). Moreover, p16 was positive in all cases where the preanalytic impression was of -IN2/3 (13/13). CONCLUSIONS: p16 IHC lacks utility in cases of morphologically obvious IN2, because the stain is positive in most cases. The LAST recommendation to use p16 IHC to support all diagnoses of -IN2 will result in performing the immunostain in many circumstances where it is not medically necessary. Among cases that are p16 negative, many have compelling high-grade morphology. The LAST perspective that the stain trumps histology may allow false-negative IHC results to prevail.

MATERIALS AND METHODS: Women with vulvodynia and asymptomatic controls at three offices at the University of Michigan were examined clinically and completed a comprehensive survey in this cross-sectional study. Cytokine/neurokine levels were determined on blood samples using established ELISA protocols. Analysis of 48 cases and 42 ethnically matched controls included descriptive statistics (median, minimal, and maximal levels of cytokines/neurokines), overall and in cases and controls. Because of left censored measurements, interval censored survival analysis was used to assess the association between case/control status and pain characteristics with cytokine/neurokine levels. RESULTS: Participants ranged in age from 19 to 60 years. Levels of IL1beta, IL1-RA, TNFalpha, IL-6, and IL-8 increased substantially after LPS stimulation, whereas no response was seen on IFNgamma or nerve growth factor (NGF). Each increased after Candida antigen stimulation, although responses to Candida antigen stimulation of IL1beta, IL-6, and TNFalpha were less robust than after LPS. Only NGF was significantly increased in vulvodynia cases compared with controls (Exp beta (95% CI) = 2.08 [1.08-3.98]) after 24-hour Candida antigen stimulation and persisted when controlled for age, use of oral contraceptives, or history of Candida vulvovaginitis. No association between cytokine/neurokine levels and pain characteristics was found. CONCLUSIONS: Compared with that of control women, whole blood from women with vulvodynia demonstrates an enhanced production of NGF, but not of a set of inflammation-related cytokines, in response to Candida antigen stimulation.

AB - OBJECTIVES: Many US children use complementary health approaches (CHAs), including some modalities that may be ineffective, unsafe, and/or costly. Yet, little is known about the prevalence and correlates of CHA use among children with developmental disabilities (DDs), as well as parent nondisclosure of CHAs used for children with DDs to health care providers. We, therefore, aimed to profile the use and nondisclosure of CHAs among US children with DDs. METHODS: We analyzed data from the 2012 National Health Interview Survey, which included the most recent Child Complementary and Alternative Medicine Supplement. The study sample was comprised of 2141 children with DDs aged 4 to 17 years. RESULTS: Nearly one-quarter (23%) of US children with DDs used CHAs. Among those with a personal health provider, 42% of parents did not disclose some or all CHAs used to the child's provider. The adjusted odds ratios of using CHAs were greater among those with female sex, higher household income, residences not in the South, difficulty accessing care, or comorbid conditions. CHA was most commonly used because "it is natural." Nondisclosure was associated with female sex, older age, having no functional limitations, less conventional services use, and use of fewer CHAs. The most common reason for nondisclosure was that the child's provider did not ask. CONCLUSION: Complementary health approach use is prevalent among US children with DDs, and nondisclosure is likely among those who use CHAs. Future intervention targeting education and communication about CHAs for parents of children with DDs and their health care providers may promote disclosure. PMID- 29570568 TI - Perceived Toddler Sleep Problems, Co-sleeping, and Maternal Sleep and Mental Health. AB - OBJECTIVE: Childhood sleep problems are associated with insufficient parental sleep and adverse maternal mental health symptoms, which may be exacerbated when mothers/toddlers co-sleep (i.e., bed/room sharing). This study examines maternal sleep duration as a mechanism linking perceived toddler sleep problems with maternal mental health and examines whether these associations vary by co sleeping, in addition to exploring alternative models. METHODS: Low-income mothers of toddlers (n = 280) (age 12-32 months) recruited from Women, Infants, and Children and pediatric clinics provided demographic information and completed questionnaires on their toddler's sleep and their own sleep duration and mental health symptoms (depressive symptoms, anxiety, and stress). Indirect and conditional indirect models were conducted to examine the relation between perceived toddler sleep problems and maternal mental health. RESULTS: Perceived toddler sleep problems were associated with an average decrease of 51 minutes in maternal sleep when co-sleeping (mean = 6.1 h). Maternal sleep duration mediated the relation between perceived toddler sleep problems and maternal symptoms of depression, anxiety, and stress for co-sleeping mothers. Maternal sleep duration did not mediate relations between maternal mental health symptoms and perceived toddler sleep problems. CONCLUSION: This study provides a conceptual model by which parent and child sleep is related to parental mental health. Practitioners might consider alternatives to co-sleeping when discussing sleep arrangements with parents. Future studies should replicate results longitudinally and examine whether reducing co-sleeping improves maternal sleep duration and reduces perceptions of toddler sleep problems. PMID- 29570569 TI - Sensitivity and Specificity of 2 Autism Screeners Among Referred Children Between 16 and 48 Months of Age. AB - OBJECTIVE: Autism screening is recommended by the American Academy of Pediatrics and the Centers for Disease Control and Prevention at ages 18 and 24 months. Popular screening tests have been validated for the age range of 16 to 30 months. However, only a minority of children with autism spectrum disorder (ASD) are identified by age 3 years, and many are not identified until after they enter school. Thus, we aimed to measure the sensitivity and specificity of 2 available screening tests for ASDs in children older than 30 months. METHODS: We assessed the sensitivity and specificity of 2 ASD screening tools administered to parents of children who were referred to a developmental clinic between the ages of 16 and 48 months: the Modified Checklist for Autism in Toddlers (M-CHAT) and the Parent's Observations of Social Interactions (POSI), which is a component of a comprehensive screening instrument called, the Survey of Well-being of Young Children. RESULTS: Both the M-CHAT and the POSI had acceptable sensitivity (>=75%) among children across the age range studied. Their specificity was limited by the fact that the study was conducted in a developmental referral clinic. CONCLUSION: Two readily available screening tools, the POSI and the M CHAT, have acceptable sensitivity in evaluating risk for autism in children at least to age 48 months. Further research should investigate their sensitivity and specificity when used in primary care settings. PMID- 29570571 TI - Cardiac Autonomic and Blood Pressure Responses to an Acute Foam Rolling Session. AB - Lastova, K, Nordvall, M, Walters-Edwards, M, Allnutt, A, and Wong, A. Cardiac autonomic and blood pressure responses to an acute foam rolling session. J Strength Cond Res 32(10): 2825-2830, 2018-Foam rolling (FR) is a self-myofascial release method that has become extremely popular among athletes and fitness enthusiasts for its ability to improve flexibility and range of motion and alleviate delayed-onset muscle soreness. However, the cardiac autonomic modulation and blood pressure (BP) responses induced by an acute FR session are currently unknown. This study evaluated the effects of an acute session of FR exercise on heart rate variability (HRV) and BP responses in healthy individuals. Fifteen (M = 8, F = 7) healthy subjects completed either an FR or nonexercise control trial in randomized order. Heart rate variability and BP measurements were collected at baseline, 10, and 30 minutes after each trial. There were significant increases (p < 0.01) in markers of vagal tone (normalized high frequency) for 30 minutes after the FR trial, whereas no changes from baseline were observed after control. There were also significant decreases (p < 0.05) in markers of sympathetic activity (normalized low frequency), sympathovagal balance (ratio of normalized low frequency to normalized high frequency), systolic BP, and diastolic BP at 10 and 30 minutes after the trial KB trial, whereas no changes from baseline were observed after the control trial. Our findings indicate that FR decreases sympathovagal balance for 30 minutes postintervention, which is concurrent with an important hypotensive effect. Further research is warranted to evaluate the potential cardiovascular protective effects of FR in diverse populations. PMID- 29570572 TI - Are Change-of-Direction Speed and Reactive Agility Independent Skills Even When Using the Same Movement Pattern? AB - Coh, M, Vodicar, J, Zvan, M, Simenko, J, Stodolka, J, Rauter, S, and Mackala, K. Are change-of-direction speed and reactive agility independent skills even when using the same movement pattern? J Strength Cond Res 32(7): 1929-1936, 2018-The purpose of this investigation was to determine whether there are differences between the 2 approaches to quantifying agility (preplanned vs. unplanned response) when reacting to a stimulus in an identical spatial scenarios. The study involved 45 male and 31 female trained athletes (age 21.2 +/- 1.78 and 20.6 +/- 1.27 years, body height 181.6 +/- 8.31 and 167.7 +/- 5.03 cm, and body mass 78.9 +/- 11.33 and 63.3 +/- 8.65 kg, respectively). A light-based reactive training system was used to measure the time to completion in a task that assessed agility by change-of-direction speed (CODS) in a preplanned condition and reactive agility (RA) in an unplanned condition across 4 spatial configurations. Sprint performance in a 30-m sprint and lower limb reactive power in a 10-m single leg jump test was also measured. Significant differences (p <= 0.05) were found between men and women in all tests and between performance in the CODS and RA condition for each spatial configuration. Significant correlations were observed between 30-m starting sprint speed and CODS and RA performance measured in a semicircle (r = 0.62, r = 0.60) and lateral (r = 0.54, r = 0.58) configuration in male athletes. The present findings suggest that CODS and RA are 2 different and independent skill domains that define agility. These qualities should be diagnosed by discrete assessments and enhanced by different training methodologies. PMID- 29570573 TI - Sexual Dimorphism in the Estimation of Upper-Limb Blood Flow Restriction in the Seated Position. AB - Borges, A, Teodosio, C, Matos, P, Mil-Homens, P, Pezarat-Correia, P, Fahs, C, and Mendonca, GV. Sexual dimorphism in the estimation of upper-limb blood flow restriction in the seated position. J Strength Cond Res 32(7): 2096-2102, 2018 Arterial occlusion pressure (AOP) is typically used to normalize blood flow restriction (BFR) during low-intensity BFR exercise. Despite strong evidence for sexual dimorphism in muscle blood flow, sex-related differences in AOP estimation remain a controversial topic. We aimed at determining whether the relationship of upper-limb AOP with arm circumference and systolic blood pressure (BP) differs between men and women resting in the seated position. Sixty-two healthy young participants (31 men: 21.7 +/- 2.3; 31 women: 22.0 +/- 2.0 years) were included in this study. Arm circumference, resting BP, and AOP were taken in the seated position. Multiple linear regression analysis was used to determine whether the relationship of AOP with arm circumference and resting BP differed between sexes. Prediction accuracy was assessed with the mean absolute percent error and Bland Altman plots. Men had higher systolic BP and larger arm circumference than women (p < 0.05). Nevertheless, AOP was similar between sexes. Arm circumference, systolic BP, and sex were all significant predictors of AOP (p < 0.05), explaining 42% of its variance. The absolute percent error was similar in both sexes (men: -0.55 +/- 7.12; women: -0.39 +/- 6.31%, p > 0.05). Bland-Altman plots showed that the mean difference between actual and estimated AOP was nearly zero in both groups, with no systematic overestimation or underestimation. In conclusion, arm circumference, systolic BP, and sex are all significant predictors of upper-limb-seated AOP. Their measurement allows for the indirect estimation of BFR pressure within the context of exercise training. PMID- 29570574 TI - Sequencing Effects of Plyometric Training Applied Before or After Regular Soccer Training on Measures of Physical Fitness in Young Players. AB - To compare the effects of short-term (i.e., 7 week) plyometric training applied before (PJT-B) or after (PJT-A) soccer practice on components of physical fitness in young soccer players, a single-blind randomized controlled trial was conducted. Post-pubertal boys aged 17.0+/-0.5 years were allocated to three groups: PJT-B (n=12), PJT-A (n=14), and control (CON; n=12). The outcome measures included tests to evaluate 20-m speed, standing long jump [SLJ], squat jump [SJ], countermovement jump [CMJ], and drop jump [DJ], 20-m multistage shuttle running speed [MSSRT], and Illinois change of direction speed [ICODT]. While the CON performed soccer-specific training, the PJT-A and PJT-B groups conducted the same soccer-specific sessions but replaced ~11% of their time with plyometric training. The PJT-B group performed plyometric exercises after a warm-up program, and the PJT-A group conducted plyometric exercises ~10 minutes after the completion of soccer training. Analyses of variance (ANOVAs) were used to detect differences between groups in all variables for pre- and post-training tests. Main effects of time (all p<.01; d=0.19-0.79) and group x time interactions (all p<.05; d=0.17-0.76) were observed for all examined variables. Post hoc analyses revealed significant increases in the PJT-B group (SLJ: 9.4%, d=1.7; CMJ: 11.2%, d=0.75; 20-m MSSRT: 9.0%, d=0.77) and the PJT-A group (SLJ: 3.1%, d=0.7; CMJ: 4.9%, d=0.27; 20-m MSSRT: 9.0%, d=0.76). Post hoc analyses also revealed significant increases in the PJT-B group (20-m speed: -7.4%, d=0.75; 20-cm DJ reactive strength index: 19.1%, d=1.4; SJ: 6.3%, d=0.44; ICODT results: -4.2%, d=1.1). In general, our study revealed that plyometric training is effective in improving measures of physical fitness in young male soccer players when combined with regular soccer training. More specifically, larger training induced effects on physical fitness were registered if plyometric training was conducted prior to soccer specific training. PMID- 29570575 TI - Evaluation of the Most Reliable Procedure of Determining Jump Height During the Loaded Countermovement Jump Exercise: Take-Off Velocity vs. Flight Time. AB - Perez-Castilla, A and Garcia-Ramos, A. Evaluation of the most reliable procedure of determining jump height during the loaded countermovement jump exercise: Take off velocity vs. flight time. J Strength Cond Res 32(7): 2025-2030, 2018-This study aimed to compare the reliability of jump height between the 2 standard procedures of analyzing force-time data (take-off velocity [TOV] and flight time [FT]) during the loaded countermovement (CMJ) exercise performed with a free weight barbell and in a Smith machine. The jump height of 17 men (age: 22.2 +/- 2.2 years, body mass: 75.2 +/- 7.1 kg, and height: 177.0 +/- 6.0 cm) was tested in 4 sessions (twice for each CMJ type) against external loads of 17, 30, 45, 60, and 75 kg. Jump height reliability was comparable between the TOV (coefficient of variation [CV]: 6.42 +/- 2.41%) and FT (CV: 6.53 +/- 2.17%) during the free weight CMJ, but it was higher for the FT when the CMJ was performed in a Smith machine (CV: 11.34 +/- 3.73% for TOV and 5.95 +/- 1.12% for FT). Bland-Altman plots revealed trivial differences (<=0.27 cm) and no heteroscedasticity of the errors (R <= 0.09) for the jump height obtained by the TOV and FT procedures, whereas the random error between both procedures was higher for the CMJ performed in the Smith machine (2.02 cm) compared with the free-weight barbell (1.26 cm). Based on these results, we recommend the FT procedure to determine jump height during the loaded CMJ performed in a Smith machine, whereas the TOV and FT procedures provide similar reliability during the free-weight CMJ. PMID- 29570576 TI - Effect of Match Factors on the Running Performance of Elite Female Soccer Players. AB - Trewin, J, Meylan, C, Varley, MC, Cronin, J, and Ling, D. Effect of match factors on the running performance of elite female soccer players. J Strength Cond Res 32(7): 2002-2009, 2018-The purpose of this study was to examine the effects of match factors on the match running of elite female soccer players. Players from the same women's national team (n = 45) were monitored during 47 international fixtures (files = 606) across 4 years (2012-2015) using 10-Hz global positioning system devices. A mixed model was used to analyze the effects of altitude, temperature, match outcome, opposition ranking, and congested schedules. At altitude (>500 m), a small increase in the number of accelerations (effect size [ES] = 0.40) and a small decrease in total distance (ES = -0.54) were observed, whereas at higher temperatures, there were decreases in all metrics (ES = -0.83 to -0.16). Playing a lower ranked team in a draw resulted in a moderate increase in high-speed running (ES = 0.89), with small to moderate decreases in total distance and low-speed running noted in a loss or a win. Winning against higher ranked opponents indicated moderately higher total distance and low-speed running (ES = 0.75), compared with a draw. Although the number of accelerations were higher in a draw against lower ranked opponents, compared with a win and a loss (ES = 0.95 and 0.89, respectively). Practitioners should consider the effect of match factors on match running in elite female soccer. PMID- 29570577 TI - Lower Extremity Horizontal Work But Not Vertical Power Predicts Lower Extremity Injury in Female Collegiate Dancers. AB - Ambegaonkar, JP, Schock, CS, Caswell, SV, Cortes, N, Hansen-Honeycutt, J, and Wyon, MA. Lower extremity horizontal work but not vertical power predicts lower extremity injury in female collegiate dancers. J Strength Cond Res 32(7): 2018 2024, 2018-Dancers often perform powerful and explosive movements that require adequate lower extremity (LE) activity in horizontal and vertical directions. We examined whether these measures were interrelated and whether they predicted LE injury status in dancers using binary logistic regressions and receiver operator characteristic (ROC) curve analyses. Forty-three collegiate female dancers (18 +/ 0.7 years; 162.6 +/- 5.9 cm; 59.4 +/- 7.1 kg) performed single leg hop (SLH, m) and vertical jump (VJ, cm) tests. Single leg hop and VJ distances were used to calculate SLH norm (as a % of body height) and vertical power (vPower, watts). Lower extremity injuries and dance exposure hours (DEhrs) were recorded for 16 weeks. Dancers had 51 injuries resulting in a 3.7/1,000 DEhr injury incidence rate (95% confidence interval [CI]: 2.7-4.7). Twenty dancers were injured, whereas 23 remained injury free. Injured dancers had significantly lower SLH norm than noninjured dancers (t = 2.7, p = 0.009, 85.2 +/- 11.2% vs. 76.8 +/- 8.4%, respectively), but vPower was similar (t = 0.6, p = 0.53, injured = 2,632.0 +/- 442.9 watts, noninjured = 2,722.7 +/- 480.0 watts). SLH norm, but not vPower significantly predicted injury status chi(1,43) = 5.9, p = 0.02. Specifically, an SLH norm cut-off value of 78.2% identified dancers at injury risk (area under the curve = 0.73, SE = 0.08, p = 0.01, 95% CI = 0.57-0.89, sensitivity = 0.75, specificity = 0.70). However, vPower was not able to identify dancers at risk (p = 0.36). vPower had moderate relationships with SLH norm (r = 0.31, p = 0.04). Compared with injured dancers, noninjured dancers had greater SLH norm but similar vPower. Only SLH norm predicted injury status in female collegiate dancers. Thus, the SLH test may possibly predict LE injury risk in dancers. Strength and conditioning coaches can prospectively use baseline SLH test screenings to identify dancers whose SLH is less than 78.2% of their height because these dancers may have increased probability of LE injury risk. Coaches can then include horizontal direction exercises when designing training programs and examine whether these programs reduce LE injury risk in female collegiate dancers. PMID- 29570578 TI - Evaluation of Seasonal Changes in Fitness, Anthropometrics, and Body Composition in Collegiate Division II Female Soccer Players. AB - Peart, AN, Nicks, CR, Mangum, M, and Tyo, BM. Evaluation of seasonal changes in fitness, anthropometrics, and body composition in collegiate division II female soccer players. J Strength Cond Res 32(7): 2010-2017, 2018-The purpose of this study was to investigate anthropometrics, body composition, aerobic and anaerobic fitness of collegiate Division II female soccer players throughout a calendar year. Eighteen (20 +/- 0.9 years) National Collegiate Athletics Association division II female soccer players from the same team participated in the study. Anthropometrics and body composition variables were assessed in addition to the counter movement jump (CMJ), Wingate Anaerobic Test (WAT), and peak oxygen uptake (V[Combining Dot Above]O2peak). Data were collected over 5 time points: end of competitive seasons (ECS1 and ECS2), beginning of off-season (BOS), end of off season (EOS), and preseason (PS). Repeated-measures analysis of variance was conducted to compare test scores among all 5 data collection points. Where appropriate, Bonferroni post hoc tests were used to determine which points were significantly different. Hip circumference decreased significantly (p < 0.001) from EOS (98.47 +/- 6.5 cm) to PS (94.46 +/- 6.8 cm). Fat mass (12.73 +/- 5.4 kg) was significantly different in ECS2 compared with BOS and EOS means (p <= 0.05) and percentage of body fat (%BF) (20.08 +/- 5.44) significantly different in ECS2 compared with ECS1, BOS, and EOS means (p <= 0.05), whereas fat-free mass (FFM) was maintained from ECS1 to ECS2. Counter movement jump, WAT, and V[Combining Dot Above]O2peak performance did not significantly change from ECS1 to ECS2. Anthropometrics and body composition results are similar to previous studies measuring Division II to professional female soccer players. Counter movement jump results remained consistent and are comparable to results on Division I female soccer players. Coaches and researchers can use these data to help design and evaluate training programs throughout a calendar year. PMID- 29570579 TI - Moderate Load Resisted Sprints do Not Improve Subsequent Sprint Performance in Varsity Level Sprinters. AB - Resisted sprint training (RST) is commonly used for performance enhancement in athletics and team sports to develop acceleration ability. Evidence suggests that RST may be effective as a short-term intervention to improve successive sprints. While these improvements have been measured in team sport athletes, limited research has considered the acute effects of RST training in sprint-trained athletes. Therefore, the aim of the current study was to determine if performing RST with varsity level sprinters using sled-equivalent resistive loads of ~45% body mass results in a potentiation effect, leading to improvements in subsequent maximal sprint performance over 0-5 m and 0-20 m. Competitive sprinters (n=20), were randomly assigned to perform a pre/post maximal 20 m sprint separated by either 3 resisted (RST group) or un-resisted (URS group) sprints. The RST or URS protocol was performed on four occasions separated by at least 7 days. No significant differences were observed between the RST and URS groups comparing changes in sprint times over 0-5 m (URS Delta = <0.01 s +/- 0.03 s, RST Delta = <0.01 s +/- 0.03 s) and 0-20 m (URS Delta = 0.013 s +/- 0.04 s, RST Delta = <0.01 s +/- 0.04 s). We conclude that resisted sprints using sled equivalent loads of 45% body mass are ineffective at inducing a potentiating effect on subsequent sprint performance in varsity level sprinters. In this population of trained athletes, greater loads may be necessary to induce a potentiating effect. PMID- 29570580 TI - Effects of Exercise Induced Muscle Damage in Well-Trained Cyclists' Aerobic and Anaerobic Performance. AB - This study purpose was to analyze the effect of EIMD in gross efficiency and in aerobic and anaerobic cycling performance. Nine well-trained cyclists (30.8 +/- 6.4 years, cycling experience 8.4 +/- 5.6 years) visited the laboratory 5 times. During the first visit, they performed a maximal incremental test on a cycle ergometer, to identify VO2max (55.2 +/- 4.9 mL.kg.min) and maximum aerobic power (Pmax; 327.0 +/- 28.5 watts). During the second visit (control), they cycled 5 minutes at 60% of Pmax, 5 minutes at 70% of Pmax, 5 minutes time-trial, and Wingate test. During the third visit, the athletes performed 10 sets of 10 counter-movement jumps, to generate EIMD. The athletes repeated the second visit tests (control) 30 minutes, 48h (fourth visit) and 96h (fifth visit) after the jumps. The RPE values increased 48h after EIMD (3.8 vs. 3.1) at 60% of Pmax. The ventilation and RER increased at 60% of Pmax (up to 4.3 L.min and 0.04, respectively) and at 70% of Pmax (up to 5.4 L.min and 0.05, respectively), mainly after 96h. There was no significant difference in VO2, VCO2, and HR in sub maximal exercises, neither in time-trial. No differences were observed in the Wingate tests. In conclusion, the EIMD didn't impair gross efficiency, nor aerobic and anaerobic performances in trained cyclists. However, despite the benefits of strength training to improve cyclists' performance, coaches must be cautious to the days after the strength training sessions, because EIMD may change the perception of maintaining a given submaximal intensity during training or competition. PMID- 29570581 TI - INTRAVITREAL GAS INJECTION WITH LASER PHOTOCOAGULATION FOR HIGHLY MYOPIC FOVEOSCHISIS: Technique and Outcome. AB - PURPOSE: To evaluate the effects of gas tamponade combined with laser photocoagulation without vitrectomy in patients with highly myopic foveoschisis. METHODS: This retrospective noncomparative case series included 30 eyes of 23 patients with highly myopic foveoschisis who were treated by intravitreal injection of 0.5 to 0.7 mL C3F8 combined with laser photocoagulation 1 week later, and remained in the face-down position for 3 weeks. The patients were followed up for at least 6 months after the treatment. The refractive status, best-corrected visual acuity, and anatomical parameters of retina observed with the optical coherence tomography before and after the treatment were recorded. RESULTS: The mean age of the 23 patients (6 men and 17 women) was 50.4 +/- 15.1 years. The average follow-up duration was 20.8 +/- 20.6 months. At the final follow-up, 23 eyes (76.7%) completely (17 eyes) or partially (6 eyes) resolved. Seventeen eyes had complete data of optical coherence tomography parameters, the mean central foveal thickness decreased significantly from 505.24 +/- 466.22 MUm to 186.41 +/- 95.36 MUm (P = 0.01), and the mean maximal macular thickness from 687.88 +/- 397.00 MUm to 313.65 +/- 83.07 MUm (P = 0.001). The mean final logarithm of the minimum angle of resolution best-corrected visual acuity (Snellen equivalent) of the 30 eyes ranged from 1.6 (20/800) to 0.2 (20/32), showing a slight improvement from 0.91 +/- 0.44 (20/163) preoperatively to 0.90 +/- 0.39 (20/160) postoperatively (P = 0.87). CONCLUSION: C3F8 tamponade combined with laser photocoagulation could be an alternative treatment for highly myopic foveoschisis.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC ND), where it is permissible to download and share the work provided it is properly cited.

AB - BACKGROUND: Data on hospitalization burden of community-acquired pneumonia (CAP) in children are very limited in China. This study aimed to estimate the hospitalization rate (HR) and population-based incidence of hospitalization of CAP for children <15 years of age in Suzhou, China. METHODS: This was a retrospective study of children hospitalized in Soochow University Affiliated Children's Hospital from January 2010 to December 2014. Children who were residents of downtown Suzhou, 29 days to <15 years of age, with discharge diagnosis codes (International Classification of Diseases, 10th revision) including J09-J18 and J20-J22 were included. All-cause clinical community acquired pneumonia (CCAP) and radiographically confirmed pneumonia (RCAP) were identified based on individual medical chart review. The HR and population-based cumulative incidence of hospitalization (HI) were calculated. RESULTS: Among 184,734 children <15 years of age admitted to Soochow University Affiliated Children's Hospital during the study period, 31,302 children were identified as having CCAP and 24,218 (77.4%) children confirmed as having RCAP. CCAP hospitalization occurred year round and peaked during winter and early spring. The overall HRs for CCAP and RCAP were 189.0 [95% confidence interval (CI): 187.1 190.9] and 146.2 (95% CI: 144-148) per 1000 hospitalizations, respectively, and the HIs per 100,000 children annually were CCAP, 3235.8 (95% CI: 3207.3-3264.2) and RCAP, 2503.5 (95% CI: 2478.3-2528.6). For children <5 years of age, the HR for CCAP was 248.4 (95% CI: 245.9-250.9) and RCAP was 194.0 (95% CI: 191.4-196.3) per 1000 hospitalizations; the HI for CCAP was 6956.2 (95% CI: 6892.8-7019.6) and 5431.9 (95% CI: 5375.4-5488.4) per 100,000 children for RCAP. The highest HR and HI were observed in children 29 days to <6 months of age: HR for CCAP was 407.4 (95% CI: 400.9-413.9) per 1000 hospitalizations and HI for CCAP was 11,203.7 (95% CI: 11,026.8-11,380.6) per 100,000 children annually. CONCLUSIONS: There is a considerable burden of CAP among children <15 years of age in Suzhou, particularly among children 29 days to <6 months of age and during winter and early spring. These data provide valuable information to monitor CAP trends over time in children of Suzhou, China. PMID- 29570587 TI - Invasive Gastrointestinal Mucormycosis: A Master Masquerader.

PMID- 29570588 TI - HLA-DR Expression on Monocyte Subsets in Critically Ill Children. AB - BACKGROUND: To longitudinally study blood monocyte subset distribution and human leukocyte antigen-DR (HLA-DR) expression on monocyte subsets in children with sepsis, post-surgery and trauma in relation to nosocomial infections and mortality. METHODS: In 37 healthy children and 37 critically ill children (12 sepsis, 11 post-surgery, 10 trauma and 4 admitted for other reasons) participating in a randomized controlled trial on early versus late initiation of parenteral nutrition-monocyte subset distribution and HLA-DR expression on monocyte subsets were measured by flow cytometry upon admission and on days 2, 3 and 4 of pediatric intensive care unit (PICU) stay. RESULTS: Upon PICU admission, critically ill children had a higher proportion of classical monocytes (CD14++CD16-) than healthy children [PICU 95% (interquartile range [IQR] 88% 98%); controls, 87% (IQR 85%-90%), P < 0.001]. HLA-DR expression was significantly decreased within all monocyte subsets and at all time points, being most manifest on classical monocytes and in patients with sepsis. Percentage of HLA-DR expressing classical monocytes [upon PICU admission 67% (IQR 44%-88%); controls 95% (IQR 92%-98%), P < 0.001], as well as the HLA-DR mean fluorescence intensity [upon PICU admission 3219 (IQR 2650-4211); controls 6545 (IQR 5558 7647), P < 0.001], decreased during PICU stay. Patients who developed nosocomial infections (n = 13) or who died (n = 6) had lower HLA-DR expression on classical monocytes at day 2 (P = 0.002) and day 3 (P = 0.04), respectively. CONCLUSIONS: Monocytic HLA-DR expression decreased during PICU stay and was lower compared with controls on all examined time points, especially on classical monocytes and in children admitted for sepsis. Low HLA-DR expression on classical monocytes was associated with nosocomial infections and death. PMID- 29570589 TI - Re-emergence of Congenital Syphilis in Ohio. AB - BACKGROUND: The recent occurrence of congenital syphilis in Columbus, OH, raised concern for an increase in syphilis among women and infants. The objectives were to examine the rates of syphilis among men, women and infants in Ohio from 2003 to 2016 and compare these rates to the rest of the United States. METHODS: This retrospective study evaluated cases of syphilis among men, women and infants from 2003 to 2016 using data from the Ohio Department of Health and the Centers for Disease Control and Prevention. RESULTS: In Ohio from 2003 to 2016, the number of all syphilis cases among women significantly increased from 153 (2.6/100,000) to 294 (5.2/100,000), respectively (b = 0.26; P = 0.001; 95% confidence interval [CI]: 0.137-0.382). From 2003 to 2016, congenital syphilis in Ohio also increased significantly from 3 (2/100,000) to 13 cases (9.3/100,000), respectively (b = 1.05; P <= 0.001; 95% CI: 0.687-1.408). The increase in congenital syphilis mirrored the increase in all cases of syphilis in women but not with the rates of primary and secondary syphilis. Among men, cases of primary and secondary syphilis increased significantly in Ohio and the rest of the United States, from 156 (2.8/100,000) and 5956 (4.2/100,000) in 2003 to 622 (10.5/100,000) and 24,724 (15.6/100,000) in 2016, respectively (Ohio: b = 0.55; P < 0.001; 95% CI: 0.426 0.679; United States: b = 0.77; P < 0.001; 95% CI: 0.629-0.916). CONCLUSIONS: The association of congenital syphilis with all syphilis cases in women highlights the importance of reporting all cases and not just primary and secondary syphilis. The increase in congenital syphilis reinforces the recommendation for repeat maternal screening during pregnancy. PMID- 29570590 TI - Osteoarticular Infections Following Open or Penetrating Trauma in Children in the Post-Community-Acquired Methicillin-resistant Staphylococcus aureus Era: The Impact of Enterobacter cloacae. AB - BACKGROUND: Most cases of pediatric osteoarticular infections (OAIs) are hematogenous in nature and caused by Staphylococcus aureus. OAI in children can also occur through direct inoculation of microorganisms secondary to penetrating or open trauma. No studies in the United States have evaluated the microbiology or outcomes of trauma-related OAI (TROAI) in children in the era of community acquired methicillin-resistant S. aureus (CA-MRSA). METHODS: Cases were identified from the inpatient infectious diseases consultation database at Texas Children's Hospital from January 2011 to December 2016. TROAI cases were those in which OAI developed following a clear history of penetrating trauma, open fracture, crush injury or traumatic amputation. Only cases with radiographic evidence of bone abscess, gross appearance of infection at the time of surgery and/or positive cultures from bone or joint were included. Complications included recurrence of infection, pathologic fracture or chronic osteomyelitis. RESULTS: During the study period, 692 consultations for OAI were performed, with 34 meeting inclusion criteria. In 68%, at least 1 organism was isolated, and the most commonly isolated organisms were S. aureus (32% overall, 21% MRSA) and Enterobacter cloacae (24%). Polymicrobial infections occurred in 38% of patients. Eighty-five percentage of patients had at least 1 surgical procedure, and 38% underwent >= 2 procedures. Eighty-two percentage of patients were discharged on oral therapy. Complications developed in 15% of patients and were more commonly associated with E. cloacae (80% vs. 14%, P = 0.007) and fungi (P = 0.03). CONCLUSION: TROAI are relatively uncommon in children but cause significant morbidity. While MRSA contributes substantially to TROAI, the highly diverse microbiology emphasizes the importance of obtaining cultures for microbiologic diagnosis and management. Clinicians should be aware of the frequency of E. cloacae in TROAI and its high risk for sequelae.

AB - Eighty-five children were diagnosed with culture-confirmed nontuberculous mycobacterial cervical lymphadenitis within the MYCOMED surveillance network from 2004 to 2013. The mean incidence sharply increased from 0.57 to 3.7 per 100,000 children per year, after the discontinuation of mandatory bacillus Calmette and Guerin immunization in 2007. Cases were documented as Mycobacterium avium (62.3%), Mycobacterium intracellulare (15.3%) and Mycobacterium lentiflavum (12.9%). Outcome was favorable in all, with or without surgery or antimycobacterial treatment. PMID- 29570592 TI - Preterm Children Have Higher Risk Than Full-term Children of Invasive Pneumococcal Disease During the First 2 Years of Life. AB - BACKGROUND: A few previous studies have reported an increased risk of invasive pneumococcal disease (IPD) in children born preterm, but this has not been investigated in a cohort study. The impact of 7-valent pneumococcal conjugate vaccine (PCV7) on IPD incidence rates in preterm children is unknown. METHODS: Data from the Medical Birth Registry of Norway (2002-2010) were linked to other national registries. In total, 628,138 children were included in our study and followed until 2 years of age. Incidence rate ratios (IRRs) and confidence intervals (CIs) were estimated with Poisson regression. RESULTS: We identified 411 cases of IPD. We observed higher rates of IPD in preterm than in full-term children for the intervals 0-23, 0-5 and 6-23 months of age, IRRs = 1.83 (95 % CI: 1.36-2.47), 2.95 (95% CI: 1.44-6.06) and 1.69 (95% CI: 1.22-2.34), respectively. The risk for IPD was reduced in the PCV7-period (2007-2010) compared with that of the pre PCV7-period (2002-2005) for children 6-23 months of age, IRRs = 0.20 (95% CI: 0.08-0.53) for preterm children and 0.28 (95% CI: 0.21 0.38) for full-term children, but not for those 0-5 months of age, IRRs = 1.94 (95% CI: 0.48-7.80) and 0.71 (95% CI: 0.38-1.33). CONCLUSIONS: Preterm children had an increased risk of IPD. After introduction of PCV7, the rate of IPD was reduced among preterm and full-term children from 6 months of age. PMID- 29570593 TI - Initial Palivizumab Dose Administration in Outpatient Clinic After Hospital Discharge. AB - BACKGROUND: Palivizumab provides passive immunity for respiratory syncytial virus (RSV), but poor adherence compromises protection. A hospital initiative promoted administration of first palivizumab doses at an outpatient clinic immediately after discharge. The objectives of this study were to evaluate the impact of the initiative on location and timing of first palivizumab dose, patient adherence, reimbursement, acquisition cost and RSV-positive hospital readmissions. METHODS: This retrospective cohort study included pediatric patients who received palivizumab from 2012 to 2016. Three groups were compared: "before initiative," "transition" and "after initiative." Patients who did not qualify for palivizumab or who were eligible for palivizumab in previous RSV seasons were excluded. Multivariable logistic and linear regressions adjusted for patients' characteristics were used in outcome analysis. RESULTS: After adjusting for patients' characteristics, there was a 13.5-fold (95% confidence interval: 5.9 30.5, P < 0.0001) increase in odds that patients would receive outpatient administration of palivizumab and 2.7-fold (95% confidence interval: 1.3-5.7, P = 0.0103) increase in odds of receiving the second dose within 35 days after initiative implementation compared with before. Although there was no significant difference in reimbursement percentage after initiative implementation (32% +/- 30% after initiative and 31% +/- 22% before), calculated palivizumab acquisition costs were 20.8% lower. RSV readmissions were not significantly different. CONCLUSIONS: Implementation of an initiative with defined workflow, multidisciplinary collaboration, and early case management efforts to obtain insurance authorization increased outpatient administration of first palivizumab doses. Patient adherence improved as demonstrated by more timely receipt of the second palivizumab dose. There was no difference in reimbursement; however, acquisition cost decreased which is valuable considering low reimbursement rates. RSV-positive readmissions did not change significantly. PMID- 29570594 TI - Acute Neuromuscular Adaptations in Response to Low-Intensity Blood-Flow Restricted Exercise and High-Intensity Resistance Exercise: Are There Any Differences? AB - Fatela, P, Reis, JF, Mendonca, GV, Freitas, T, Valamatos, MJ, Avela, J, and Mil Homens, P. Acute neuromuscular adaptations in response to low-intensity blood flow restricted exercise and high-intensity resistance exercise: are there any differences? J Strength Cond Res 32(4): 902-910, 2018-Numerous studies have reported similar neuromuscular adaptations between low-intensity (LI) blood-flow restricted exercise (BFRE) and high-intensity (HI) resistance training. Unfortunately, none of these experimental designs individualized blood flow restriction (BFR) levels to each participant. Thus, their findings are difficult to interpret. We aimed at comparing the acute effects of LI BFR (80% of absolute vascular occlusion pressure) with LI non-BFR and HI training on muscle torque, activation, and neuromuscular fatigue. Ten men (23.8 +/- 5.4 years) exercised at 20 and 75% of 1 repetition maximum with and without BFR (for LI). Blood flow restriction pressure was determined individually using resting blood-flow measurements. Torque was determined during maximal voluntary contractions (MVCs) at pre-exercise and postexercise time points. Surface electromyographic activity (root mean square [RMS] and median frequency [MF]) was recorded for the rectus femoris (RF) and vastus medialis (VM) muscles, before and after each session of training, during isometric contractions at 20% MVC. Torque decreased post-HI and LI BFR (-9.5 and -7.8%, respectively; p < 0.01), but not after LI non-BFR. The MF was reduced following HI training in the VM and the RF muscles (-5.3 and -12.5%, respectively; p <= 0.05). Conversely, the impact of LI BFR on reducing MF was limited to the RF muscle (-10.7%, p <= 0.05). Finally, when compared to all other conditions, RMS values were consistently higher during submaximal contractions performed after HI training (p <= 0.05). Thus, we conclude that, despite enhancing the acute magnitude of muscular activation and fatigue, LI BFR exercise exerts a less profound impact on neuromuscular function than HI resistance training. PMID- 29570595 TI - Influence of a Cluster Set Configuration on the Adaptations to Short-Term Power Training. AB - Morales-Artacho, AJ, Padial, P, Garcia-Ramos, A, Perez-Castilla, A, and Feriche, B. Influence of a cluster set configuration on the adaptations to short-term power training. J Strength Cond Res 32(4): 930-937, 2018-This study investigated the effects of a traditional (TT) vs. cluster (CT) resistance training on the lower-body force, velocity, and power output. Nineteen males were allocated to a CT or a TT group and took part of a 3-week resistance training (2 weekly sessions). CT involved 6 sets of 3 * 2 repetitions (30 seconds rest every 2 repetitions and 4 minutes 30 seconds between sets). TT comprised 6 sets of 6 continuous repetitions (5 minutes rest between sets). Before and after the training period, force (F25, F50, F75), velocity (V25, V50, V75), and power (P25, P50, P75) were obtained during the countermovement jump (CMJ) exercise at 3 external loading conditions (25, 50, and 75% of body mass). Individual linear regressions were used to determine the force-velocity profile including the Slope, estimated maximal theoretical force (F0), velocity (V0), and power (P0). After CT, very-likely moderate increments in P25 were observed compared with TT (p = 0.011, ES = 0.55) because of a very-likely moderate rise in V25 (p = 0.001, ES = 0.71). No significant differences were observed in any of the F-v profile variables between the TT and CT groups (p >= 0.207, ES <= 0.31). Our results suggest that 3 weeks of muscle power training including cluster set configurations are more efficient at inducing velocity and power adaptations specific to the training load. PMID- 29570596 TI - Quantifying the Physical Response to a Contemporary Amateur Boxing Simulation. AB - Finlay, MJ, Greig, M, and Page, RM. Quantifying the physical response to a contemporary amateur boxing simulation. J Strength Cond Res 32(4): 1005-1012, 2018-This study examined the physical response to a contemporary boxing-specific exercise protocol (BSEP), based on notational analysis of amateur boxing. Nine male senior elite amateur boxers completed a 3 * 3-minute BSEP, with a 1-minute passive recovery period interspersing each round. Average (HRave) and peak (HRpeak) heart rates, average (V[Combining Dot Above]O2ave) and peak oxygen consumptions (V[Combining Dot Above]O2peak), blood lactate (BLa) concentrations, rating of perceived exertion, and both triaxial and uniaxial PlayerLoad metrics were recorded during the completion of the BSEP. Blood lactate concentration increased significantly in each round (Round 1 = 2.4 +/- 1.3 mmol.L; Round 2 = 3.3 +/- 1.7 mmol.L; Round 3 = 4.3 +/- 2.6 mmol.L). Significantly lower HRave and HRpeak values were found in the first round (HRave: 150 +/- 15 b.min; HRpeak: 162 +/- 12 b.min) when compared with the second (HRave: 156 +/- 16 b.min; HRpeak: 166 +/- 13 b.min) and third (HRave: 150 +/- 15 b.min; HRpeak: 169 +/- 14 b.min). No significant differences were found in any of the V[Combining Dot Above]O2 or PlayerLoad metrics recorded during the BSEP. The BSEP based on notational analysis elicited a fatigue response across rounds, confirming its validity. The BSEP can be used as a training tool for boxing-specific conditioning with implications for reduced injury risk, and to assess the physical response to boxing-specific interventions. Moreover, the BSEP can also be manipulated to suit all levels of participants or training phases, with practical applications in performance monitoring and microcycle periodization. PMID- 29570597 TI - Maximum Dynamic Lower-Limb Strength Was Maintained During 24-Week Reduced Training Frequency in Previously Sedentary Older Women. AB - Walker, S, Serrano, J, and Van Roie, E. Maximum dynamic lower-limb strength was maintained during 24-week reduced training frequency in previously sedentary older women. J Strength Cond Res 32(4): 1063-1071, 2018-There is little study into the effects of reducing strength training below the recommended twice weekly frequency, particularly in older women, despite the possibility that individuals will encounter periods of reduced training frequency. The purpose of the present study was to determine the effects of a period of reduced training frequency on maximum strength and muscle mass of the lower limbs in comparison with the recommended training frequency of twice per week. After an initial 12-week period, where all subjects trained twice per week, a reduced strength training group (RST) trained once per week, whereas another strength training group (ST) continued to train twice per week for 24 weeks. A nontraining age-matched control group (CON) was used for comparison. All subjects were tested for leg press 1 repetition maximum (1RM), electromyogram (EMG) amplitude of vastus lateralis and medialis, and quadriceps cross-sectional area (CSA) measured by panoramic ultrasound at weeks 0, 12, and 36. Both ST and RST continued to increase 1RM during the reduced training frequency period compared with control (~8% and ~5% vs. ~-3%, respectively; p <= 0.05). Accompanying these changes were significant increases in EMG amplitude in both ST and RST (p <= 0.05). However, the initial gains in quadriceps CSA made from week 0 to week 12 in RST were lost when training once per week (RST ~-5%). Therefore, reduced training frequency in this population does not adversely affect maximum strength or muscle activity but can negatively affect muscle mass, even reversing training-induced gains. Older individuals not training at least twice per week may compromise potential increases in muscle mass, important in counteracting effects of aging. PMID- 29570598 TI - Effects of Resistance Training on Cardiovascular Function in Patients With Peripheral Artery Disease: A Randomized Controlled Trial. AB - Gomes, APF, Correia, MA, Soares, AHG, Cucato, GG, Lima, AHRA, Cavalcante, BR, Sobral-Filho, DC, and Ritti-Dias, RM. Effects of resistance training on cardiovascular function in patients with peripheral artery disease: A randomized controlled trial. J Strength Cond Res 32(4): 1072-1080, 2018-The aim of this study was to analyze the effects of resistance training on cardiovascular function of patients with peripheral artery disease (PAD). In total, 30 patients with PAD were invited to participate in this randomized controlled trial, randomly allocated to a control (n = 15, 66 +/- 2 years; stretching and relaxation exercises) or resistance training group (n = 15, 60 +/- 3 years; 3 sets of 10 repetitions of 8 whole-body exercises, with a 2-minute interval between sets). Resting and 24-hour blood pressure (BP), cardiac output, systemic vascular resistance, and autonomic variables were obtained before and after 12 weeks of intervention. A blinded investigator performed all analyses. After 12 weeks of intervention there was maintenance of resting systolic, diastolic, and mean BP (p > 0.18), cardiac output (p = 0.46), and systemic vascular resistance (p = 0.55) in both groups. There was a time effect reduction in heart rate (p = 0.02), accompanied by changes in cardiac autonomic modulation (p = 0.03). There were no changes in 24-hour systolic, diastolic, and mean BP, heart rate, or rate pressure product (p > 0.05). The BP variability decreased in systolic (asleep, p = 0.003), diastolic (24 hours and awake, p = 0.001), and mean (24 hours and asleep, p < 0.02) only in the resistance training (RT) group. Twelve weeks of RT did not change resting and 24-hour BP, or their hemodynamic and autonomic determinants in patients with PAD; however, there were decreases in BP variability, indicating that it could be considered as an alternative to reducing cardiovascular risk in patients with PAD. PMID- 29570599 TI - Increased Leg Bone Mineral Density and Content During the Initial Years of College Sport. AB - Scerpella, JJ, Buehring, B, Hetzel, SJ, and Heiderscheit, BC. Increased leg bone mineral density and content during the initial years of college sport. J Strength Cond Res 32(4): 1123-1130, 2018-Bone mineral density (BMD) and bone mineral content (BMC) data are useful parameters for evaluating how training practices promote bone health. We used dual-energy X-ray absorptiometry (DXA) to longitudinally assess sport-specific growth in leg and total body BMD/BMC over the initial 2 years of collegiate training. Eighty-five Division 1 collegiate basketball, hockey, and soccer athletes (50 males and 35 females; age 19.0 [0.8] years) underwent annual DXA scans. Leg and total body BMD/BMC were compared within and across two 1-year intervals (periods 1 and 2) using repeated-measures analysis of variance, adjusting for age, sex, race, and sport. Leg BMD, leg BMC, and total body BMC all increased over period 1 (0.05 g.cm [p = 0.001], 0.07 kg [p = 0.002], and 0.19 kg [p < 0.001] respectively). Changes in period 2 compared with period 1 were smaller for leg BMD (p = 0.001), leg BMC (p < 0.001), leg fat mass (p = 0.028), and total BMC (p = 0.005). Leg lean mass increased more during period 2 than period 1 (p = 0.018). Sports participation was the only significant predictor of change in leg BMD. Significant increases in both leg BMD and BMC were demonstrated over both 2-year periods, with greater gains during period 1. These gains highlight the importance of attentive training procedures, capitalizing on attendant physical benefits of increased BMD/BMC. Additional research in young adults, evaluating bone mass acquisition, will optimize performance and decrease risk of bone stress injury among collegiate athletes. PMID- 29570600 TI - The Age of Peak Marathon Performance in Cross-Country Skiing-The "Engadin Ski Marathon". AB - Knechtle, B and Nikolaidis, PT. The age of peak marathon performance in cross country skiing-the "Engadin Ski Marathon." J Strength Cond Res 32(4): 1131-1136, 2018-The age of the best endurance performance has been well investigated in flat city running marathons. However, we have no knowledge about the age of peak marathon performance in cross-country skiing, which would be of great practical value for athletes and coaches. Therefore, the aim of the present study was to examine the age of peak marathon performance in cross-country skiing. Participants were 162,991 men and 34,833 women competing between 1998 and 2016 in the "Engadin Ski Marathon." We considered the fastest for both women and men, and all finishers in 1-year age intervals. The men-to-women ratio increased across ages (r = 0.55, p < 0.0001). Men (44.27 +/- 0.03 years, 15.73 +/- 0.01 km.h) were 5.98 +/- 0.07 years older and 2.14 +/- 0.02 km.h faster (p < 0.0001) than women (38.29 +/- 0.06 years, 13.58 +/- 0.01 km.h). Considering the fastest participants in 1-year age intervals, the fastest speed for men (30.33 km.h) was achieved at the age of 29 years, and for women (28.76 km.h) at the age of 24 years. Considering all participants, the fastest speed for men (17.69 km.h) was observed at the age of 18 years, whereas for women (15.76 km.h) it was at the age of 17 years. In summary, for athletes and coaches, the age of peak performance in cross country skiers competing in a marathon distance was much younger and closer to the peak of aerobic capacity than what was found by previous studies in marathon road runners. PMID- 29570601 TI - Effect of Compression Garments on Controlled Force Output After Heel-Rise Exercise. AB - Kato, E, Nakamura, M, and Takahashi, H. Effect of compression garments on controlled force output after heel-rise exercise. J Strength Cond Res 32(4): 1174 1179, 2018-The purpose of this study was to elucidate the effects of compression garments (CG) on controlled force output after strenuous exercise. Sixteen healthy volunteers completed trials both with CG and without CG (control trial: CON) on 2 separate, random days which were at least 1 month apart. Both trials required participants to perform heel-rise exercises from maximal dorsiflexion to maximal plantar flexion 20 times with a single leg. The subjects repeated 3 sets of the exercise and took a rest for 2 minutes between sets. Before and after the heel-rise exercise, mechanical (stiffness) and architectural properties of the gastrocnemius medialis muscle were evaluated using the ultrasound method. Also, isometric maximal voluntary contraction (MVC) of plantar flexion was measured, and the subjects maintained 20% MVC of plantar flexion torque for 20 seconds as steadily as possible (steadiness task) as an index of force control. Repeated 2 way analysis of variance analysis (CG/CON * time) indicated that all the parameters declined immediately after heel-rise exercise in both CG and CON trials. Maximal voluntary contraction did not show different tendencies between CG and CON trials, but muscle stiffness and steadiness declined less in CG than CON (p < 0.05). In conclusion, CG are considered to positively benefit controlled force output after strenuous exercise. PMID- 29570602 TI - Live Bacterial Vectors-A Promising DNA Vaccine Delivery System. AB - Vaccination is one of the most successful immunology applications that has considerably improved human health. The DNA vaccine is a new vaccine being developed since the early 1990s. Although the DNA vaccine is promising, no human DNA vaccine has been approved to date. The main problem facing DNA vaccine efficacy is the lack of a DNA vaccine delivery system. Several studies explored this limitation. One of the best DNA vaccine delivery systems uses a live bacterial vector as the carrier. The live bacterial vector induces a robust immune response due to its natural characteristics that are recognized by the immune system. Moreover, the route of administration used by the live bacterial vector is through the mucosal route that beneficially induces both mucosal and systemic immune responses. The mucosal route is not invasive, making the vaccine easy to administer, increasing the patient's acceptance. Lactic acid bacterium is one of the most promising bacteria used as a live bacterial vector. However, some other attenuated pathogenic bacteria, such as Salmonella spp. and Shigella spp., have been used as DNA vaccine carriers. Numerous studies showed that live bacterial vectors are a promising candidate to deliver DNA vaccines. PMID- 29570603 TI - Real-Time Estimation of Population Exposure to PM2.5 Using Mobile- and Station Based Big Data. AB - Extremely high fine particulate matter (PM2.5) concentration has been a topic of special concern in recent years because of its important and sensitive relation with health risks. However, many previous PM2.5 exposure assessments have practical limitations, due to the assumption that population distribution or air pollution levels are spatially stationary and temporally constant and people move within regions of generally the same air quality throughout a day or other time periods. To deal with this challenge, we propose a novel method to achieve the real-time estimation of population exposure to PM2.5 in China by integrating mobile-phone locating-request (MPL) big data and station-based PM2.5 observations. Nationwide experiments show that the proposed method can yield the estimation of population exposure to PM2.5 concentrations and cumulative inhaled PM2.5 masses with a 3-h updating frequency. Compared with the census-based method, it introduced the dynamics of population distribution into the exposure estimation, thereby providing an improved way to better assess the population exposure to PM2.5 at different temporal scales. Additionally, the proposed method and dataset can be easily extended to estimate other ambient pollutant exposures such as PM10, O3, SO2, and NO2, and may hold potential utilities in supporting the environmental exposure assessment and related policy-driven environmental actions.

The as-synthesized SnO2 nanoflowers consisted of cuboid-like SnO2 nanorods with tetragonal structures. A great increase in the relative content of surface-adsorbed oxygen was observed after the vacuum annealing treatment, and this increase could have been due to the increase in surface oxygen vacancies serving as preferential adsorption sites for oxygen species. Annealing treatment resulted in an 8% increase in the specific surface area of the samples. Moreover, the conductivity of the sensors decreased after the annealing treatment, which should be attributed to the increase in electron scattering around the defects and the compensated donor behavior of the oxygen vacancies due to the surface oxygen adsorption. The hydrogen sensors of the annealed samples, compared to those of the unannealed samples, exhibited a much higher sensitivity and faster response rate. The sensor response factor and response rate increased from 27.1% to 80.2% and 0.34%/s to 1.15%/s, respectively. This remarkable enhancement in sensing performance induced by the annealing treatment could be attributed to the larger specific surface areas and higher amount of surface-adsorbed oxygen, which provides a greater reaction space for hydrogen. Moreover, the sensors with annealed SnO2 nanoflowers also exhibited high selectivity towards hydrogen against CH4, CO, and ethanol.

AB - With the increased use of high-throughput sequencing methods, new viruses infecting Prunus spp. are being discovered and characterized, especially in the family Betaflexiviridae. Double-stranded RNAs from symptomatic leaves of a Japanese apricot (Prunusmume) tree from Japan were purified and analyzed by Illumina sequencing. Blast comparisons of reconstructed contigs showed that the P. mume sample was infected by a putative novel virus with homologies to Cherry virus A (CVA) and to the newly described Currant virus A (CuVA), both members of genus Capillovirus. Completion of the genome showed the new agent to have a genomic organization typical of capilloviruses, with two overlapping open reading frames encoding a large replication-associated protein fused to the coat protein (CP), and a putative movement protein (MP). This virus shares only, respectively, 63.2% and 62.7% CP amino acid identity with the most closely related viruses, CVA and CuVA. Considering the species demarcation criteria in the family and phylogenetic analyses, this virus should be considered as representing a new viral species in the genus Capillovirus, for which the name of Mume virus A is proposed.

AB - Due to synergistic effects, combinatorial drugs are widely used for treating complex diseases. However, combining drugs and making them synergetic remains a challenge. Genetic disease genes are considered a promising source of drug targets with important implications for navigating the drug space. Most diseases are not caused by a single pathogenic factor, but by multiple disease genes, in particular, interacting disease genes. Thus, it is reasonable to consider that targeting epistatic disease genes may enhance the therapeutic effects of combinatorial drugs. In this study, synthetic lethality gene pairs of tumors, similar to epistatic disease genes, were first targeted by combinatorial drugs, resulting in the enrichment of the combinatorial drugs with cancer treatment, which verified our hypothesis. Then, conventional epistasis detection software was used to identify epistatic disease genes from the genome wide association studies (GWAS) dataset. Furthermore, combinatorial drugs were predicted by targeting these epistatic disease genes, and five combinations were proven to have synergistic anti-cancer effects on MCF-7 cells through cell cytotoxicity assay. Combined with the three-dimensional (3D) genome-based method, the epistatic disease genes were filtered and were more closely related to disease. By targeting the filtered gene pairs, the efficiency of combinatorial drug discovery has been further improved.

AB - BACKGROUND: The effect of sugar-sweetened beverages (SSBs) on satiety and short term food intake (FI) regulation in girls has received little attention. The objective of the present study was to compare the effect of pre-meal consumption of commercially available SSBs on subjective appetite and short-term FI in 9-14 year-old girls. The methods we used include using a randomized crossover design in which 28 girls consumed isovolumetric amounts (350 mL) of a fruit drink (154 kcal), cola (158 kcal), 1% chocolate milk (224 kcal), or water (control; 0 kcal) on four separate mornings. Subjective appetite and thirst were measured at regular intervals via visual analogue scales (VAS) and FI was assessed at 60 min post-beverage consumption. The results show that subjective appetite and thirst decreased after all beverages, but did not differ among beverages. Short-term FI was suppressed following consumption of chocolate milk (15%; p < 0.001) and cola (11%; p = 0.02) compared to the water control. However, cumulative energy intake (beverage (kcal) + test meal (kcal)) was not affected by beverage type. In conclusion, chocolate milk and cola, but not fruit drink, suppressed FI in girls while cumulative FI did not differ among treatments.

AB - We demonstrate synthesis of the ternary intermetallic MgNi3B2 using autogenous pressure from the reaction of NaBH4 with Mg and Ni metal powder. The decomposition of NaBH4 to H2 and B2H6 commences at low temperatures in the presence of Mg and/or Ni and promotes formation of Ni-borides and MgNi3B2 with the increase in temperature. MgNi3B2 aggregates with Ni-boride cores are formed when the reaction temperature is >670 degrees C and autogenous pressure is >1.7 MPa. Morphologies and microstructures suggest that solid-gas and liquid-gas reactions are dominant mechanisms and that Ni-borides form at a lower temperature than MgNi3B2. Magnetic measurements of the core-shell MgNi3B2 aggregates are consistent with ferromagnetic behaviour in contrast to stoichiometric MgNi3B2 which is diamagnetic at room temperature. PMID- 29570608 TI - Antioxidative Effect of Quetiapine on Acute Ultraviolet-B-Induced Skin and HaCaT Cell Damage. AB - Quetiapine is a new type of antipsychotic drug, with effective protection of pheochromocytoma PC12 cells from oxidative stress-induced apoptosis. Ultraviolet B radiation can increase reactive oxygen species (ROS) production, resulting in significant inflammatory responses in damaged skin. Thus, the purpose of this study is to explore whether quetiapine protects the skin from intermediate-wave ultraviolet (UVB)-induced damage through antioxidant stress. In vivo, we found quetiapine treatment was able to significantly decrease skin thickness, erythema, and edema, as well as inflammation compared to control group. Moreover, quetiapine treatment increased the activities of antioxidant enzymes, including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). In addition, it reduced the production of malondialdehyde (MDA), a kind of oxidized lipid. In vitro, we found that quetiapine blocked UVB-induced intracellular ROS generation and maintained the cell activity at a normal level. Furthermore, we tested the phosphorylation of p38 both in vivo and in vitro, and we found that quetiapine could inhibit phosphorylation of p38, which is caused by UVB irradiation. We concluded that quetiapine was able to relieve UVB-induced skin damage through its antioxidative properties. These effects might be associated with p38 MAPK signaling pathway. PMID- 29570610 TI - Dietary Sialyllactose Does Not Influence Measures of Recognition Memory or Diurnal Activity in the Young Pig. AB - Sialic acid (SA) is an integral component of gangliosides and signaling molecules in the brain and its dietary intake may support cognitive development. We previously reported that feeding sialyllactose, a milk oligosaccharide that contains SA, alters SA content and diffusivity in the pig brain. The present research sought to expand upon such results and describe the effects of feeding sialyllactose on recognition memory and sleep/wake activity using a translational pig model. Pigs were provided ad libitum access to a customized milk replacer containing 0 g/L or 380 g/L of sialyllactose from postnatal day (PND) 2-22. Beginning on PND 15, pigs were fitted with accelerometers to track home-cage activity and testing on the novel object recognition task began at PND 17. There were no significant effects of diet on average daily body weight gain, average daily milk intake, or the gain-to-feed ratio during the study (all p >= 0.11). Pigs on both diets were able to display recognition memory on the novel object recognition task (p < 0.01), but performance and exploratory behavior did not differ between groups (all p >= 0.11). Total activity and percent time spent sleeping were equivalent between groups during both day and night cycles (all p >= 0.56). Dietary sialyllactose did not alter growth performance of young pigs, and there was no evidence that providing SA via sialyllactose benefits the development of recognition memory or gross sleep-related behaviors. PMID- 29570611 TI - Macular Xanthophylls Are Related to Intellectual Ability among Adults with Overweight and Obesity. AB - Excess adiposity or obesity has been inversely related to cognitive function and macular xanthophyll status. However, whether the neuroprotective effects of macular xanthophylls on cognitive function are independent of excess adiposity is unclear. We investigated the relationship between macular xanthophylls and intellectual ability among adults (N = 114) between 25 and 45 years with overweight and obesity (>=25 kg/m2). Dual energy X-ray absorptiometry and heterochromatic flicker photometry were used to assess whole body adiposity (%Fat) and macular pigment optical density (MPOD), respectively. Dietary xanthophylls (lutein and zeaxanthin) were assessed using 7-day diet records. The Kaufman Brief Intelligence Test-2 (KBIT-2) was used to assess general intelligence (IQ) as well as fluid and crystallized intelligence. Bivariate correlations revealed that MPOD was inversely related to %Fat and positively associated with IQ and fluid intelligence. Although %Fat was inversely correlated to IQ and fluid intelligence, this relationship did not persist following adjustment for sex and MPOD. Further, MPOD was an independent predictor of IQ and fluid intelligence. However, no significant relationships were observed between MPOD and crystalized intelligence. These results suggest that macular xanthophylls are selectively related to fluid intelligence, regardless of degree of adiposity among adults with overweight and obesity. PMID- 29570612 TI - Synthesis, Optical, and Structural Studies of Iron Sulphide Nanoparticles and Iron Sulphide Hydroxyethyl Cellulose Nanocomposites from Bis (Dithiocarbamato)Iron(II) Single-Source Precursors. AB - In this study, Fe(II) complexes of phenyldithiocarbamate, dimethyldithiocarbamate and imidazolyldithiocarbamate were used as single-source precursors to prepare iron sulphide nanoparticles by thermolysis in oleic acid/octadecylamine (ODA) at 180 degrees C. The nanoparticles were dispersed into hydroxyethyl cellulose (HEC) to prepare iron sulphide/HEC nanocomposites. Ultraviolet-Visible (UV-Vis), Photoluminescence (PL), Fourier Transform Infrared (FTIR), powder X-ray diffraction (pXRD), high-resolution transmission electron microscopy (HRTEM), Field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDS) were used to characterize the iron sulphide nanoparticles and corresponding HEC nanocomposites. The absorption spectra studies revealed that the nanoparticles were blue shifted due to quantum confinement and the optical band gaps of the nanoparticles are 4.85 eV for FeS1, 4.36 eV for FeS2, and 4.77 eV for FeS3. The emission maxima are red-shifted and broader for the nanoparticles prepared from phenyldithiocarbamate. Rod-like and spherically shaped iron sulphide particles were observed from the HRTEM images. The crystallite sizes from the HRTEM images are 23.90-38.89 nm for FeS1, 4.50-10.50 nm for FeS2, and 6.05-6.19 nm for FeS3 iron sulphide nanoparticles, respectively. pXRD diffraction patterns confirmed that FeS1 is in the pyrrhotite-4M crystalline phase, FeS2 is in the pyrrhotite phase, and FeS3 is in the troilite phase of iron sulphide. The phases of the iron sulphide nanoparticles indicate that the nature of the precursor complex affects the obtained crystalline phase. FTIR spectra studies confirmed the incorporation of the nanoparticles in the HEC matrix by the slight shift of the O-H and C-O bonds and the intense peaks on the nanoparticles. FESEM images of the iron sulphide nanoparticles showed flake-like or leaf-like morphologies with some hollow spheres. The EDS confirmed the formation of iron sulphide nanoparticles by showing the peaks of Fe and S. PMID- 29570613 TI - Branched Chain Amino Acids: Beyond Nutrition Metabolism. AB - Branched chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, immunity and disease in humans and animals. As the most abundant of essential amino acids (EAAs), BCAAs are not only the substrates for synthesis of nitrogenous compounds, they also serve as signaling molecules regulating metabolism of glucose, lipid, and protein synthesis, intestinal health, and immunity via special signaling network, especially phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signal pathway. Current evidence supports BCAAs and their derivatives as the potential biomarkers of diseases such as insulin resistance (IR), type 2 diabetes mellitus (T2DM), cancer, and cardiovascular diseases (CVDs). These diseases are closely associated with catabolism and balance of BCAAs. Hence, optimizing dietary BCAA levels should have a positive effect on the parameters associated with health and diseases. This review focuses on recent findings of BCAAs in metabolic pathways and regulation, and underlying the relationship of BCAAs to related disease processes. PMID- 29570614 TI - Transcriptomic and GC-MS Metabolomic Analyses Reveal the Sink Strength Changes during Petunia Anther Development. AB - Petunia, which has been prevalently cultivated in landscaping, is a dicotyledonous herbaceous flower of high ornamental value. Annually, there is a massive worldwide market demand for petunia seeds. The normal development of anther is the necessary prerequisite for the plants to generate seeds. However, the knowledge of petunia anther development processes is still limited. To better understand the mechanisms of petunia anther development, the transcriptomes and metabolomes of petunia anthers at three typical development stages were constructed and then used to detect the gene expression patterns and primary metabolite profiles during the anther development processes. Results suggested that there were many differentially-expressed genes (DEGs) that mainly participated in photosynthesis and starch and sucrose metabolism when DEGs were compared between the different development stages of anthers. In this study, fructose and glucose, which were involved in starch and sucrose metabolism, were taken as the most important metabolites by partial least-squares discriminate analysis (PLS-DA). Additionally, the qRT-PCR analysis of the photosynthetic related genes all showed decreased expression trends along with the anther development. These pieces of evidence indicated that the activities of energy and carbohydrate metabolic pathways were gradually reduced during all the development stages of anther, which affects the sink strength. Overall, this work provides a novel and comprehensive understanding of the metabolic processes in petunia anthers. PMID- 29570615 TI - Neuroimmune Tau Mechanisms: Their Role in the Progression of Neuronal Degeneration. AB - Progressive neurodegenerative pathologies in aged populations are an issue of major concern worldwide. The microtubule-associated protein tau is able to self aggregate to form abnormal supramolecular structures that include small oligomers up to complex polymers. Tauopathies correspond to a group of diseases that share tau pathology as a common etiological agent. Since microglial cells play a preponderant role in innate immunity and are the main source of proinflammatory factors in the central nervous system (CNS), the alterations in the cross-talks between microglia and neuronal cells are the main focus of studies concerning the origins of tauopathies. According to evidence from a series of studies, these changes generate a feedback mechanism reactivating microglia and provoking constant cellular damage. Thus, the previously summarized mechanisms could explain the onset and progression of different tauopathies and their functional/behavioral effects, opening the window towards an understanding of the molecular basis of anomalous tau interactions. Despite clinical and pathological differences, increasing experimental evidence indicates an overlap between tauopathies and synucleinopathies, considering that neuroinflammatory events are involved and the existence of protein misfolding. Neurofibrillary tangles of pathological tau (NFT) and Lewy bodies appear to coexist in certain brain areas. Thus, the co-occurrence of synucleinopathies with tauopathies is evidenced by several investigations, in which NFT were found in the substantia nigra of patients with Parkinson's disease, suggesting that the pathologies share some common features at the level of neuroinflammatory events. PMID- 29570616 TI - Efficacy of Nutritional Interventions on Inflammatory Markers in Haemodialysis Patients: A Systematic Review and Limited Meta-Analysis. AB - Low-grade chronic inflammation is prevalent in patients undergoing haemodialysis (HD) treatment and is linked to the development of premature atherosclerosis and mortality. The non-pharmacological approach to treat inflammation in HD patients through nutritional intervention is well cited. We aimed to assess the efficacy of different nutritional interventions at improving inflammatory outcomes in HD patients, based on markers such as C-reactive protein (CRP), interleukin-6 (IL 6), and tumour necrosis factor-alpha (TNF-alpha). We searched PubMed, Cochrane Library, and Embase for randomized controlled trials (RCT) published before June 2017. Inclusion criteria included RCTs on adult patients on maintenance HD treatment with duration of nutritional interventions for a minimum 4 weeks. Risk of bias was assessed using the Jadad score. In total, 46 RCTs experimenting different nutritional interventions were included in the review and categorized into polyphenols rich foods, omega-3 fatty acids, antioxidants, vitamin D, fibres, and probiotics. Meta-analyses indicated significant reduction in CRP levels by omega-3 fatty acids (Random model effect: -0.667 mg/L, p < 0.001) and vitamin E (fixed model effect: -0.257 mg/L, p = 0.005). Evidence for other groups of nutritional interventions was inconclusive. In conclusion, our meta-analysis provided evidence that omega-3 fatty acids and vitamin E could improve inflammatory outcomes in HD patients. PMID- 29570617 TI - Dietary Intake of Magnesium or Calcium and Chemotherapy-Induced Peripheral Neuropathy in Colorectal Cancer Patients. AB - Chemotherapy-induced peripheral neuropathy (CIPN) is a common and severe side effect in colorectal cancer (CRC) patients. This study assessed the association between habitual dietary intake of magnesium or calcium and prevalence and severity of chronic CIPN in CRC patients receiving adjuvant chemotherapy. For this prospective cohort study, 196 CRC patients were considered. Magnesium and calcium intake was determined using a food frequency questionnaire at diagnosis, during and after chemotherapy. Chronic CIPN was assessed 12 months after diagnosis using the quality of life questionnaire CIPN20. Prevalence ratios were calculated to assess the association between magnesium or calcium intake and the prevalence of CIPN. Multivariable linear regression analysis was used to assess the association between magnesium or calcium intake and severity of CIPN. CIPN was reported by 160 (82%) patients. Magnesium intake during chemotherapy was statistically significantly associated with lower prevalence of CIPN (prevalence ratio (PR) 0.53, 95% confidence interval (CI) 0.32, 0.92). Furthermore, higher dietary intake of magnesium during (beta -1.08, 95% CI -1.95, -0.22) and after chemotherapy (beta -0.93, 95% CI -1.81, -0.06) was associated with less severe CIPN. No associations were found for calcium intake and the prevalence and severity of CIPN. To conclude, we observed an association between higher dietary magnesium intake and lower prevalence and severity of CIPN in CRC patients. PMID- 29570619 TI - Rhizosphere Microbiome Modulators: Contributions of Nitrogen Fixing Bacteria towards Sustainable Agriculture. AB - Rhizosphere microbiome which has been shown to enhance plant growth and yield are modulated or influenced by a few environmental factors such as soil type, plant cultivar, climate change and anthropogenic activities. In particular, anthropogenic activity, such as the use of nitrogen-based chemical fertilizers, is associated with environmental destruction and this calls for a more ecofriendly strategy to increase nitrogen levels in agricultural land. This feat is attainable by harnessing nitrogen-fixing endophytic and free-living rhizobacteria. Rhizobium, Pseudomonas, Azospirillum and Bacillus, have been found to have positive impacts on crops by enhancing both above and belowground biomass and could therefore play positive roles in achieving sustainable agriculture outcomes. Thus, it is necessary to study this rhizosphere microbiome with more sophisticated culture-independent techniques such as next generation sequencing (NGS) with the prospect of discovering novel bacteria with plant growth promoting traits. This review is therefore aimed at discussing factors that can modulate rhizosphere microbiome with focus on the contributions of nitrogen fixing bacteria towards sustainable agricultural development and the techniques that can be used for their study. PMID- 29570618 TI - Lysophosphatidic Acid Signaling in Obesity and Insulin Resistance. AB - Although simple in structure, lysophosphatidic acid (LPA) is a potent bioactive lipid that profoundly influences cellular signaling and function upon binding to G protein-coupled receptors (LPA1-6). The majority of circulating LPA is produced by the secreted enzyme autotaxin (ATX). Alterations in LPA signaling, in conjunction with changes in autotaxin (ATX) expression and activity, have been implicated in metabolic and inflammatory disorders including obesity, insulin resistance, and cardiovascular disease. This review summarizes our current understanding of the sources and metabolism of LPA with focus on the influence of diet on circulating LPA. Furthermore, we explore how the ATX-LPA pathway impacts obesity and obesity-associated disorders, including impaired glucose homeostasis, insulin resistance, and cardiovascular disease. PMID- 29570620 TI - Dietary Fiber and Telomere Length in 5674 U.S. Adults: An NHANES Study of Biological Aging. AB - The relationship between fiber intake and telomere length was evaluated using a cross-sectional design and an NHANES sample of 5674 U.S. adults. Another purpose was to test the impact of potential confounders on the association. Fiber consumption was measured using a 24 h recall and telomere length was indexed using the quantitative polymerase chain reaction method. Overall, the U.S. adults had low fiber intake (median: 6.6 g per 1000 kcal)-less than one-half the recommendation of the Dietary Guidelines for Americans. With age, gender, race, housing status, and misreported energy intake controlled, the relationship between fiber intake per 1000 kcal and telomere length was linear (F = 9.5, p = 0.0045). Specifically, for each 1 g increment in fiber intake per 1000 kcal, telomeres were 8.3 base pairs longer. Because each additional year of chronological age was associated with telomeres that were 15.5 base pairs shorter, results suggest that a 10 g increase in fiber intake per 1000 kcal would correspond with telomeres that are 83 base pairs longer. On average, this would equate to 5.4 fewer years of biologic aging (83 / 15.5). With smoking, BMI, alcohol use, and physical activity controlled, as well as the other covariates, each 10 g increment in fiber accounted for telomeres that were 67 base pairs longer (F = 7.6, p = 0.0101), a biologic aging difference of about 4.3 years. In conclusion, significant fiber consumption accounts for longer telomeres and less biologic aging than lower levels of fiber intake.

In this work, highly ordered porous membranes have been prepared successfully on ice substrates using aath figure method. Based on the theory of Pickering emulsion system and capillary flow, particle assisted membrane formation was analyzed. Another two sorts of new membranes SiO2/C membrane and hierarchical porous polymer (HPP) membrane, which were obtained by modification of the BPPO-SiO2 membrane by calcination and etching, were set up in a further study. Their properties were investigated through the methods of scanning electron microscopy (SEM), fourier transform infrared spectrometry (FTIR), ultraviolet spectrum (UV), capillary electrophoresis (CE), contact angle, and water flux tests. All these results demonstrate that both surface hydrophilicity and fouling resistance of the membrane would be improved by using SiO2 as a filler. The membranes with high permeability and antifouling properties were used for microfiltration applications. PMID- 29570621 TI - The Melatonin Signaling Pathway in a Long-Term Memory In Vitro Study. AB - The activation of cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB) via phosphorylation in the hippocampus is an important signaling mechanism for enhancing memory processing. Although melatonin is known to increase CREB expression in various animal models, the signaling mechanism between melatonin and CREB has been unknown in vitro. Thus, we confirmed the signaling pathway between the melatonin receptor 1 (MT1) and CREB using melatonin in HT-22 cells. Melatonin increased MT1 and gradually induced signals associated with long-term memory processing through phosphorylation of Raf, ERK, p90RSK, CREB, and BDNF expression. We also confirmed that the calcium, JNK, and AKT pathways were not involved in this signaling pathway by melatonin in HT-22 cells. Furthermore, we investigated whether melatonin regulated the expressions of CREB BDNF associated with long-term memory processing in aged HT-22 cells. In conclusion, melatonin mediated the MT1-ERK-p90RSK-CREB-BDNF signaling pathway in the in vitro long-term memory processing model and increased the levels of p-CREB and BDNF expression in melatonin-treated cells compared to untreated HT-22 cells in the cellular aged state. Therefore, this paper suggests that melatonin induces CREB signaling pathways associated with long-term memory processing in vitro. PMID- 29570623 TI - Correction: Becker, B. et al.

AB - This review describes advances in the literature since 2000 in the area of reactions of vinylsulfonium and vinylsulfoxonium salts, with a particular emphasis on stereoselective examples. Although the chemistry of vinylsulfonium salts was first explored back in the 1950s, and that of vinylsulfoxonium salts in the early 1970s, there has been renewed interest in these compounds since the turn of the century. This has been largely due to an increased appreciation for the many synthetic possibilities associated with these valuable electrophiles. The development of improved routes to vinylsulfonium salts allowing for their in situ generation has played a part in accelerating their study. In general, reactions of the two sulfur salt classes follow a similar mechanistic pathway: initial conjugate addition of a nucleophile to the beta-position, followed by protonation of an ylide intermediate, and cyclization of tethered anion to afford monocyclic or bicyclic product (e.g., cyclopropane, aziridine, oxazole, oxazolidinone, gamma-lactam or gamma-lactone). Alternatively, reactions involve formation of an ylide intermediate followed by intramolecular Johnson-Corey Chaykovsky reaction (epoxidation or cyclopropanation), and subsequent cyclization to afford the desired bicyclic product (e.g., fused bicyclic epoxide or cyclopropane). PMID- 29570625 TI - Impact of Scyphozoan Venoms on Human Health and Current First Aid Options for Stings. AB - Cnidaria include the most venomous animals of the world. Among Cnidaria, Scyphozoa (true jellyfish) are ubiquitous, abundant, and often come into accidental contact with humans and, therefore, represent a threat for public health and safety. The venom of Scyphozoa is a complex mixture of bioactive substances-including thermolabile enzymes such as phospholipases, metalloproteinases, and, possibly, pore-forming proteins-and is only partially characterized. Scyphozoan stings may lead to local and systemic reactions via toxic and immunological mechanisms; some of these reactions may represent a medical emergency. However, the adoption of safe and efficacious first aid measures for jellyfish stings is hampered by the diffusion of folk remedies, anecdotal reports, and lack of consensus in the scientific literature. Species specific differences may hinder the identification of treatments that work for all stings. However, rinsing the sting site with vinegar (5% acetic acid) and the application of heat (hot pack/immersion in hot water) or lidocaine appear to be substantiated by evidence. Controlled clinical trials or reliable models of envenomation are warranted to confirm the efficacy and safety of these approaches and identify possible species-specific exceptions. Knowledge of the precise composition of Scyphozoa venom may open the way to molecule-oriented therapies in the future. PMID- 29570627 TI - Localization of an Underwater Control Network Based on Quasi-Stable Adjustment. AB - There exists a common problem in the localization of underwater control networks that the precision of the absolute coordinates of known points obtained by marine absolute measurement is poor, and it seriously affects the precision of the whole network in traditional constraint adjustment. Therefore, considering that the precision of underwater baselines is good, we use it to carry out quasi-stable adjustment to amend known points before constraint adjustment so that the points fit the network shape better. In addition, we add unconstrained adjustment for quality control of underwater baselines, the observations of quasi-stable adjustment and constrained adjustment, to eliminate the unqualified baselines and improve the results' accuracy of the two adjustments. Finally, the modified method is applied to a practical LBL (Long Baseline) experiment and obtains a mean point location precision of 0.08 m, which improves by 38% compared with the traditional method. PMID- 29570626 TI - Angiotensin II-Induced Mesangial Cell Damaged Is Preceded by Cell Membrane Permeabilization Due to Upregulation of Non-Selective Channels. AB - Connexin43 (Cx43), pannexin1 (Panx1) and P2X7 receptor (P2X7R) are expressed in kidneys and are known to constitute a feedforward mechanism leading to inflammation in other tissues. However, the possible functional relationship between these membrane channels and their role in damaged renal cells remain unknown. In the present work, we found that MES-13 cells, from a cell line derived from mesangial cells, stimulated with angiotensin II (AngII) developed oxidative stress (OS, thiobarbituric acid reactive species (TBARS) and generated pro-inflammatory cytokines (ELISA; IL-1beta and TNF-alpha). The membrane permeability increased progressively several hours before the latter outcome, which was a response prevented by Losartan, indicating the involvement of AT1 receptors. Western blot analysis showed that the amount of phosphorylated MYPT (a substrate of RhoA/ROCK) and Cx43 increased progressively and in parallel in cells treated with AngII, a response followed by an increase in the amount in Panx1 and P2X7R. Greater membrane permeability was partially explained by opening of Cx43 hemichannels (Cx43 HCs) and Panx1 channels (Panx1 Chs), as well as P2X7Rs activation by extracellular ATP, which was presumably released via Cx HCs and Panx1 Chs. Additionally, inhibition of RhoA/ROCK blocked the progressive increase in membrane permeability, and the remaining response was explained by the other non-selective channels. The rise of activity in the RhoA/ROCK-dependent pathway, as well as in Cx HCs, P2X7R, and to a minor extent in Panx1 Chs led to higher amounts of TBARS and pro-inflammatory cytokines. We propose that AngII-induced mesangial cell damage could be effectively inhibited by concomitantly inhibiting the RhoA/ROCK-dependent pathway and one or more non-selective channel(s) activated through this pathway. PMID- 29570628 TI - A Study and Review of Effects of Botulinum Toxins on Mast Cell Dependent and Independent Pruritus. AB - Pruriceptive itch originates following activation of peripheral sensory nerve terminals when pruritogens come in contact with the skin. The ability of botulinum neurotoxins (BoNTs) to attenuate transmitter release from afferent terminals provides a rationale for studying its effect on pruritus. This study investigated the effects of BoNT/A1 and BoNT/B1 on mast cell dependent (Compound 48/80:48/80) and independent (Chloroquine:CQ) scratching. C57Bl/6 male mice received intradermal injection of 1.5 U of BoNT/A1, BoNT/B1 or saline 2, 7, 14 and 21 days prior to ipsilateral 48/80 or CQ at the nape of the neck. Ipsilateral hind paw scratching was determined using an automated recording device. The effect of BoNTs on 48/80 mediated mast cell degranulation was analyzed in human and murine mast cells and the presence of SNAREs was determined using qPCR, immunostaining and Western blot. Pre-treatment with BoNT/A1 and BoNT/B1 reduced 48/80 and CQ induced scratching behavior starting on day 2 with reversal by day 21. Both serotypes inhibited 48/80 induced mast cell degranulation. qPCR and immunostaining detected SNAP-25 mRNA and protein, respectively, in mast cells, however, Western blots did not. This study demonstrates the long-lasting anti pruritic effects of two BoNT serotypes, in a murine pruritus model using two different mechanistically driven pruritogens. These data also indicate that BoNTs may have a direct effect upon mast cell degranulation.

AB - Epstein-Barr virus (EBV) is related to a variety of malignant tumors, and its encoded protein, latent membrane protein 2 (LMP2), is an effective target antigen that is widely used to construct vector vaccines. However, the model cells carrying LMP2 have still not been established to assess the oncolytic effect of LMP2-related vaccines at present. In this study, TC-1-GLUC-LMP2 tumor cells were constructed as target cells to evaluate the anti-tumor effects of LMP2-assosiated vaccines. The results showed that both LMP2 and Gaussia luciferase (GLuc) genes could be detected by polymerase chain reaction (PCR) and reverse transcription polymerase chain reaction (RT-PCR) in TC-1-GLUC-LMP2 cells. Western blot results showed that the LMP2 and Gaussia luciferase proteins were stably expressed in tumor cells for at least 30 generations. We mixed 5 * 104 LMP2-specific mouse splenic lymphocytes with 5 * 103 TC-1-GLUC-LMP2 target cells and found that the target cells were killed as the specific killing effect was obviously enhanced by the increased quantities of LMP2-peptide stimulated spleens. Furthermore, the tumor cells could not be observed in the mice inoculated TC-1-GLUC-LMP2 cells after being immunized with vaccine-LMP2, while the vaccine-NULL immunized mice showed that tumor volume gradually grew with increased inoculation time. These results indicated that the TC-1-GLUC-LMP2 cells stably expressing LMP2 and GLuc produced tumors in mice, and that the LMP2-specific cytotoxic T lymphocyte (CTL) effectively killed the cells in vitro and in vivo, suggesting that TC-1-GLUC-LMP2 cells can be used as model cells to assess the immune and antitumor effects of LMP2-related vaccines.

AB - Natural O-alkyl-glycerolipids, also known as alkyl-ether-lipids (AEL), feature a long fatty alkyl chain linked to the glycerol unit by an ether bond. AEL are ubiquitously found in different tissues but, are abundant in shark liver oil, breast milk, red blood cells, blood plasma, and bone marrow. Only a few AEL are commercially available, while many others with saturated or mono-unsaturated alkyl chains of variable length are not available. These compounds are, however, necessary as standards for analytical methods. Here, we investigated different reported procedures and we adapted some of them to prepare a series of 1-O-alkyl glycerols featuring mainly saturated alkyl chains of various lengths (14:0, 16:0, 17:0, 19:0, 20:0, 22:0) and two monounsaturated chains (16:1, 18:1). All of these standards were fully characterized by NMR and GC-MS. Finally, we used these standards to identify the AEL subtypes in shark and chimera liver oils. The distribution of the identified AEL were: 14:0 (20-24%), 16:0 (42-54%) and 18:1 (6 16%) and, to a lesser extent, (0.2-2%) for each of the following: 16:1, 17:0, 18:0, and 20:0. These standards open the possibilities to identify AEL subtypes in tumours and compare their composition to those of non-tumour tissues.

AB - Phenotypic diversity generated through altered gene expression is a primary mechanism facilitating evolutionary response in natural systems. By linking the phenotype to genotype through transcriptomics, it is possible to determine what changes are occurring at the molecular level. High phenotypic diversity has been documented in rattlesnake venom, which is under strong selection due to its role in prey acquisition and defense. Rattlesnake venom can be characterized by the presence (Type A) or absence (Type B) of a type of neurotoxic phospholipase A 2 (PLA 2 ), such as Mojave toxin, that increases venom toxicity. Mojave rattlesnakes (Crotalus scutulatus), represent this diversity as both venom types are found within this species and within a single panmictic population in the Sonoran Desert. We used comparative venom gland transcriptomics of nine specimens of C. scutulatus from this region to test whether expression differences explain diversity within and between venom types. Type A individuals expressed significantly fewer toxins than Type B individuals owing to the diversity of C type lectins (CTLs) and snake venom metalloproteinases (SVMPs) found in Type B animals. As expected, both subunits of Mojave toxin were exclusively found in Type A individuals but we found high diversity in four additional PLA 2 s that was not associated with a venom type. Myotoxin a expression and toxin number variation was not associated with venom type, and myotoxin a had the highest range of expression of any toxin class. Our study represents the most comprehensive transcriptomic profile of the venom type dichotomy in rattlesnakes and C. scutulatus. Even intra-specifically, Mojave rattlesnakes showcase the diversity of snake venoms and illustrate that variation within venom types blurs the distinction of the venom dichotomy. PMID- 29570633 TI - Magnetron-Sputtered, Biodegradable FeMn Foils: The Influence of Manganese Content on Microstructure, Mechanical, Corrosion, and Magnetic Properties. AB - FeMn alloys show a great potential for the use as a biodegradable material for medical vascular implants. To optimize the material properties, with respect to the intended application, new fabrication methods also have to be investigated. In this work different Fe-FeMn32 multilayer films were deposited by magnetron sputtering. The deposition was done on a substrate structured by UV lithography. This technique allows the fabrication of in-situ structured foils. In order to investigate the influence of the Mn content on the material properties foils with an overall Mn content of 5, 10, 15, and 17 wt % were fabricated. The freestanding foils were annealed post-deposition, in order to homogenize them and adjust the material properties. The material was characterized in terms of microstructure, corrosion, mechanical, and magnetic properties using X-ray diffraction, electron microscopy, electrochemical polarization, immersion tests, uniaxial tensile tests, and vibrating sample magnetometry. Due to the unique microstructure that can be achieved by the fabrication via magnetron sputtering, the annealed foils showed a high mechanical yield strength (686-926 MPa) and tensile strength (712 1147 MPa). Owing the stabilization of the non-ferromagnetic epsilon- and gamma phase, it was shown that even Mn concentrations of 15-17 wt % are sufficient to distinctly enhance the magnetic resonance imaging (MRI) compatibility of FeMn alloys. PMID- 29570632 TI - Micro-Economics of Apoptosis in Cancer: ncRNAs Modulation of BCL-2 Family Members. AB - In the last few years, non-coding RNAs (ncRNAs) have been a hot topic in cancer research. Many ncRNAs were found to regulate the apoptotic process and to play a role in tumor cell resistance to treatment. The apoptotic program is on the frontline as self-defense from cancer onset, and evasion of apoptosis has been classified as one of the hallmarks of cancer responsible for therapy failure. The B-cell lymphoma 2 (BCL-2) family members are key players in the regulation of apoptosis and mediate the activation of the mitochondrial death machinery in response to radiation, chemotherapeutic agents and many targeted therapeutics. The balance between the pro-survival and the pro-apoptotic BCL-2 proteins is strictly controlled by ncRNAs. Here, we highlight the most common mechanisms exerted by microRNAs, long non-coding RNAs and circular RNAs on the main mediators of the intrinsic apoptotic cascade with particular focus on their significance in cancer biology.

AB - The environment of space provides many challenges to the human physiology and therefore to extended habitation and exploration[...]. PMID- 29570634 TI - Current Strategies to Enhance Anti-Tumour Immunity. AB - The interaction of the immune system with cancer is complex, but new approaches are resulting in exciting therapeutic benefits. In order to enhance the immune response to cancer, immune therapies seek to either induce high avidity immune responses to tumour specific antigens or to convert the tumour to a more pro inflammatory microenvironment. Strategies, including vaccination, oncolytic viruses, and adoptive cell transfer all seek to induce anti-tumour immunity. To overcome the suppressive tumour microenvironment checkpoint inhibitors and modulators of regulatory cell populations have been investigated. This review summarizes the recent advances in immune therapies and discusses the importance of combination therapies in the treatment of cancers. PMID- 29570637 TI - Design, Synthesis, and SAR of Novel 2-Glycinamide Cyclohexyl Sulfonamide Derivatives against Botrytis cinerea. AB - N-(2-trifluoromethyl-4-chlorophenyl)-2-oxocyclohexyl sulfonamide (chesulfamide) is in the limelight as a novel fungicide, and has fungicidal activity against Botrytis cinerea. For exploring more novel structures, 33 new compounds were synthesized by N-alkylation and acid-amine coupling reactions with chesulfamide as the core moiety, and their structures were characterized and established by 1H NMR, 13C-NMR, MS, and elemental analysis. The structure of (1R,2S)-2-(2-(N-(4 chloro-2-trifluoromethylphenyl)sulfamoyl)-cyclohexylamino)-N-(2 trifluoromethylphenyl) acetamide (II-19) was defined by X-ray single crystal diffraction. The in vivo and in vitro fungicidal activities against B. cinerea were evaluated. The bioassay results of mycelial growth demonstrated that most compounds exhibited excellent inhibitory activity against B. cinerea at 50 MUg mL 1, and 7 compounds showed lower EC50 values than boscalid (EC50 = 4.46 MUg mL-1) against B. cinerea (CY-09). In cucumber pot experiment, the inhibitory rates of four compounds (II-4, II-5, II-12, and II-13) against B. cinerea were 90.48, 93.45, 92.86, and 91.07, which were better than cyprodinil (88.69%), the best performing of all controls. In tomato pot experiment, the control efficacy of two analogs (II-8 and II-15) were 87.98 and 87.97% at 200 MUg mL-1, which were significantly higher than boscalid (78.10%). Most compounds have an excellent fungicidal effect on B. cinerea, with potential as a lead compound for developing new pesticides. PMID- 29570636 TI - Encapsulation of Curcumin-Loaded Liposomes for Colonic Drug Delivery in a pH Responsive Polymer Cluster Using a pH-Driven and Organic Solvent-Free Process. AB - The present study aimed to develop and optimize liposome formulation for the colonic delivery of biologically active compounds. A strategy to facilitate such targeting is to formulate liposomes with a polymer coating sensitive to the pH shifts in the gastrointestinal tract. To this end, liposomes encapsulating curcumin-chosen as the biologically active compound model-and coated with the pH responsive polymer Eudragit S100 were prepared and characterized. Curcumin was encapsulated into small unilamellar vesicles (SUVs) by the micelle-to-vesicle transition method (MVT) in a simple and organic solvent-free way. Curcumin-loaded liposomes were coated with Eudragit S100 by a fast and easily scalable pH-driven method. The prepared liposomes were evaluated for size, surface morphology, entrapment efficiency, stability, in vitro drug release, and curcumin antioxidant activity. In particular, curcumin-loaded liposomes displayed size lower than 100 nm, encapsulation efficiency of 98%, high stability at both 4 degrees C and 25 degrees C, high in vitro antioxidant activity, and a cumulative release that was completed within 200 min. A good Eudragit S100 coating which did not alter the properties of the curcumin-loaded liposomes was obtained. The present work therefore provides a fast and solvent-free method to prepare pH-responsive polymer-coated liposomes for the colonic delivery of biologically active compounds. PMID- 29570638 TI - The Association between Potential Exposure to Magazine Ads with Voluntary Health Warnings and the Perceived Harmfulness of Electronic Nicotine Delivery Systems (ENDS). AB - (1) Background: Several brands of electronic nicotine delivery systems (ENDS) carry voluntary health warning messages. This study examined how potential exposure to ENDS magazine ads with these voluntary health warnings were associated with the perceived harmfulness of ENDS. (2) Methods: Risk perception measures and self-reported exposure to ENDS ads were obtained from the 2014 Georgia State University (GSU) Tobacco Products and Risk Perceptions Survey of a nationally representative sample of U.S. adults. We examined the association between potential exposure to magazine ads with warnings and the perceived harms of ENDS relative to cigarettes, using binary logistic regressions and controlling for general ENDS ad exposure and socio-demographic characteristics. (3) Results: Potential exposure to ENDS magazine ads with warnings was associated with a lower probability of considering ENDS to be more or equally harmful compared to cigarettes, particularly among non-smokers (OR = 0.16; 95% CI: 0.04-0.77). In addition, ad exposure, ENDS use history, race/ethnicity, gender, education, and income were also associated with harm perceptions. (4) Conclusions: This study did not find evidence that magazine ads with warnings increased misperceptions that ENDS are equally or more harmful than cigarettes. With more ENDS advertisements carrying warnings, more research is needed to determine how the warnings in advertisements convey relative harm information to consumers and the public. PMID- 29570640 TI - Assessment of Potentially Toxic Elements as Non-Point Sources of Contamination in the Upper Crocodile Catchment Area, North-West Province, South Africa. AB - The concentration of potential toxic elements (PTEs) in the Upper Crocodile river catchment area in North-west Province, South Africa, was investigated. Water and sediment samples were collected among different land uses in the upper Crocodile River catchment area and analysed using inductively-coupled plasma-mass spectrometry (ICP-MS). Several guidelines were used to gauge the level of contamination and possible toxic effect of PTEs. The physicochemical analysis showed that electrical conductivity (EC), pH, and total dissolved solids (TDS) values complied with the recommended values of Department of Water and Forestry (DWAF) guidelines for South Africa. The average concentration of Cu, Pb, Cd, Zn, As, Cr, Al, and Mn in the water samples were lower than the recommended levels for water-quality guidelines for aquatic environments except for Fe, which exceeded the recommended values of DWAF of 0.1 mg/L and EPA (US) of 0.3 mg/L. The level of contamination was measured using the enrichment factor, contamination factor, and geoaccumulation index. The level of Cr was above the stipulated threshold limit of the sediment quality guideline for adverse biological effects, suggesting an ecotoxicology risk of anthropogenic origin, which was confirmed by statistical analysis. The non-point sources of PTEs are spatially distributed according to land-use types and are strongly correlated to land use.

AB - Due to the enhanced piezoelectric properties, excellent mechanical properties and tunable electric properties, one-dimensional (1D) piezoelectric materials have shown their promising applications in nanogenerators (NG), sensors, actuators, electronic devices etc. To present a clear view about 1D piezoelectric materials, this review mainly focuses on the characterization and optimization of the piezoelectric properties of 1D nanomaterials, including semiconducting nanowires (NWs) with wurtzite and/or zinc blend phases, perovskite NWs and 1D polymers. Specifically, the piezoelectric coefficients, performance of single NW-based NG and structure-dependent electromechanical properties of 1D nanostructured materials can be respectively investigated through piezoresponse force microscopy, atomic force microscopy and the in-situ scanning/transmission electron microcopy. Along with the introduction of the mechanism and piezoelectric properties of 1D semiconductor, perovskite materials and polymers, their performance improvement strategies are summarized from the view of microstructures, including size-effect, crystal structure, orientation and defects. Finally, the extension of 1D piezoelectric materials in field effect transistors and optoelectronic devices are simply introduced. PMID- 29570641 TI - Micro-Doppler Effect Removal in ISAR Imaging by Promoting Joint Sparsity in Time Frequency Domain. AB - For micromotion scatterers with small rotating radii, the micro-Doppler (m-D) effect interferes with cross-range compression in inverse synthetic aperture radar (ISAR) imaging and leads to a blurred main body image. In this paper, a novel method is proposed to remove the m-D effect by promoting the joint sparsity in the time-frequency domain. Firstly, to obtain the time-frequency representations of the limited measurements, the short-time Fourier transform (STFT) was modelled by an underdetermined equation. Then, a new objective function was used to measure the joint sparsity of the STFT entries so that the joint sparse recovery problem could be formulated as a constrained minimization problem. Similar to the smoothed l 0 (SL0) algorithm, a steepest descend approach was used to minimize the new objective function, where the projection step was tailored to make it suitable for m-D effect removal. Finally, we utilized the recovered STFT entries to obtain the main body echoes, based on which cross-range compression could be realized without m-D interference. After all contaminated range cells were processed by the proposed method, a clear main body image could be achieved. Experiments using both the point-scattering model and electromagnetic (EM) computation validated the performance of the proposed method. PMID- 29570642 TI - Competitive Deep-Belief Networks for Underwater Acoustic Target Recognition. AB - Underwater acoustic target recognition based on ship-radiated noise belongs to the small-sample-size recognition problems. A competitive deep-belief network is proposed to learn features with more discriminative information from labeled and unlabeled samples. The proposed model consists of four stages: (1) A standard restricted Boltzmann machine is pretrained using a large number of unlabeled data to initialize its parameters; (2) the hidden units are grouped according to categories, which provides an initial clustering model for competitive learning; (3) competitive training and back-propagation algorithms are used to update the parameters to accomplish the task of clustering; (4) by applying layer-wise training and supervised fine-tuning, a deep neural network is built to obtain features. Experimental results show that the proposed method can achieve classification accuracy of 90.89%, which is 8.95% higher than the accuracy obtained by the compared methods. In addition, the highest accuracy of our method is obtained with fewer features than other methods. PMID- 29570643 TI - Stretchable, Flexible, Scalable Smart Skin Sensors for Robotic Position and Force Estimation. AB - The design and validation of a continuously stretchable and flexible skin sensor for collaborative robotic applications is outlined. The skin consists of a PDMS skin doped with Carbon Nanotubes and the addition of conductive fabric, connected by only five wires to a simple microcontroller. The accuracy is characterized in position as well as force, and the skin is also tested under uniaxial stretch. There are also two examples of practical implementations in collaborative robotic applications. The stationary position estimate has an RMSE of 7.02 mm, and the sensor error stays within 2.5 +/- 1.5 mm even under stretch. The skin consistently provides an emergency stop command at only 0.5 N of force and is shown to maintain a collaboration force of 10 N in a collaborative control experiment. PMID- 29570644 TI - Effects of Lysozyme on the Activity of Ionic of Fluoroquinolone Species. AB - Fluoroquinolones (FQs) constitute an important class of biologically active broad spectrum antibacterial drugs that are which are in contact with many biological fluids under different acidity conditions. We studied the reactivity of ciprofloxacin (Cpx) and levofloxacin (Lev) and their interaction with lysozyme (Lyz) at different pH values, using UV-visible absorption, fluorescence, infrared spectroscopies supported by DFT calculation and docking. In addition, by antimicrobial assays, the biological consequences of the interaction were evaluated. DFT calculation predicted that the FQ cationic species present at acid pH have lower stabilization energies, with an electric charge rearrangement because of their interactions with solvent molecules. NBO and frontier orbital calculations evidenced the role of two charged centers, NH2+ and COO-, for interactions by electronic delocalization effects. Both FQs bind to Lyz via a static quenching with a higher interaction in neutral medium. The interaction induces a structural rearrangement in beta-sheet content while in basic pH a protective effect against the denaturation of Lyz was inferred. The analysis of thermodynamic parameters and docking showed that hydrophobic, electrostatic forces and hydrogen bond are the responsible of Cpx-Lyz and Lev-Lyz associations. Antimicrobial assays evidenced an antagonist effect of Lyz in acid medium while in neutral medium the FQs' activities were not modified by Lyz. PMID- 29570645 TI - A Framework to Design the Computational Load Distribution of Wireless Sensor Networks in Power Consumption Constrained Environments. AB - In this paper, we present a work based on the computational load distribution among the homogeneous nodes and the Hub/Sink of Wireless Sensor Networks (WSNs). The main contribution of the paper is an early decision support framework helping WSN designers to take decisions about computational load distribution for those WSNs where power consumption is a key issue (when we refer to "framework" in this work, we are considering it as a support tool to make decisions where the executive judgment can be included along with the set of mathematical tools of the WSN designer; this work shows the need to include the load distribution as an integral component of the WSN system for making early decisions regarding energy consumption). The framework takes advantage of the idea that balancing sensors nodes and Hub/Sink computational load can lead to improved energy consumption for the whole or at least the battery-powered nodes of the WSN. The approach is not trivial and it takes into account related issues such as the required data distribution, nodes, and Hub/Sink connectivity and availability due to their connectivity features and duty-cycle. For a practical demonstration, the proposed framework is applied to an agriculture case study, a sector very relevant in our region. In this kind of rural context, distances, low costs due to vegetable selling prices and the lack of continuous power supplies may lead to viable or inviable sensing solutions for the farmers. The proposed framework systematize and facilitates WSN designers the required complex calculations taking into account the most relevant variables regarding power consumption, avoiding full/partial/prototype implementations, and measurements of different computational load distribution potential solutions for a specific WSN. PMID- 29570646 TI - Preparation of Flame Retardant Polyacrylonitrile Fabric Based on Sol-Gel and Layer-by-Layer Assembly. AB - This paper aims to develop a novel method, i.e., sol-gel combined with layer-by layer assembly technology, to impart flame retardancy on polyacrylonitrile (PAN) fabrics. Silica-sol was synthesized via the sol-gel process and acted as cationic solution, and phytic acid (PA) was used as the anionic medium. Flame-retardant treated PAN fabric (FR-PAN) could achieve excellent flame retardancy with 10 bilayer (10BL) coating through layer-by-layer assembly. The structure of the fabrics was characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The thermal stability and flame retardancy were evaluated by thermogravimetric (TG) analysis, cone calorimetry (CC) and limiting oxygen index (LOI). The LOI value of the coated fabric was up to 33.2 vol % and the char residue at 800 degrees C also increased to 57 wt %. Cone calorimetry tests revealed that, compared to the control fabric, the peak of heat release rate (PHRR) and total heat release (THR) of FR-PAN decreased by 66% and 73%, respectively. These results indicated that sol-gel combined with layer by-layer assembly technique could impart PAN fabric with satisfactory flame retardant properties, showing an efficient flame retardant strategy for PAN fabric. PMID- 29570647 TI - Identification, Characterization, and Expression Analysis of a FMRFamide-Like Peptide Gene in the Common Chinese Cuttlefish (Sepiella japonica). AB - The peptide FMRFamide is one of the well-known peptides involved in multiple physiological processes in the phylum Mollusca. In this study, a FMRFamide gene (GenBank accession No. KJ933411) was identified in a cuttlefish species called Sepiella japonica and was designated as SjFMRFamide. The total length of the SjFMRFamide sequence was found to be 1880 bp while the open reading frame contained 996 bp encoding a protein of 331 amino acid residues with a predicted isoelectric point (pI) and molecular weight (MW) of 9.18 and 38.8 kDa along with a 333 bp 5'-untranslated region (UTR) and 551 bp 3'-UTR. The deduced SjFMRFamide precursor protein contains one signal peptide and expresses four kinds FMRFamide related peptides including a single copy of FLRFamide, ALSGDAFLRFamide, and FIRFamide and multiple copies of FMRFamide. Results of phylogenetic relation analysis strongly indicated that the sequence of this gene shares high identity with the genes of known FMRFamides. Spatial expression analysis indicated the highest mRNA expression of SjFMRFamide in the brain of male and female cuttlefishes among the eight tissues analyzed. An in situ hybridization assay of the brain indicated that SjFMRFamide was transcribed in several functional lobes, which suggests that it might be related to many physiological regulatory mechanisms. This is the first study describing FMRFamide in S. japonica and the results may contribute to future studies of neuropeptide evolution or may prove useful for the development of aquaculture methods for this cuttlefish species. PMID- 29570648 TI - Potential of Cellulose Functionalized with Carboxylic Acid as Biosorbent for the Removal of Cationic Dyes in Aqueous Solution. AB - In the last decade, adsorption has been used to minimize the pollution caused by dyes, which represents a serious environmental problem. In this context, this work reports the preparation of phthalic anhydride-modified cellulose (PhCel), through the reaction of cellulose (Cel) with phthalic anhydride (Ph). The efficiency of the reaction was observed by elemental analysis, Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and thermogravimetry/derivative thermogravimetry (TG/DTG). The adsorbent matrix (Cel and PhCel) was used in the removal of crystal violet (CV) and methylene blue (MB) dyes in aqueous medium. In the kinetic study, the experimental data obtained had the best fit to the pseudo-first-order model. In general, the isotherms obtained at different temperatures had a best fit to the model proposed by Langmuir, and the CV and MB adsorption process in adsorbent matrixes can be favored strictly by hydrogen bonds and/or electrostatic interactions for Cel and electrostatic interactions for PhCel. PMID- 29570649 TI - Investigating the Interaction of Ascorbic Acid with Anthocyanins and Pyranoanthocyanins. AB - Juices colored by anthocyanins experience color loss related to fortification with ascorbic acid (AA), thought to be the result of condensation at Carbon-4 of anthocyanins. To further understand this mechanism, pyranoanthocyanins, having a fourth-ring covalently occupying Carbon-4, were synthesized to compare its reactivity with AA against that of anthocyanins. Pyranoanthocyanins were synthesized by combining chokeberry anthocyanins with pyruvic acid. AA (250-1000 mg/L) was added to either chokeberry extract, cyanidin-3-galactoside, or 5 Carboxypyranocyanidin-3-galactoside. Samples were stored in the dark for 5 days at 25 degrees C and spectra (380-700 nm), color (CIE-L*c*h*), and composition changes (HPLC-MS/MS) were monitored. Extensive bleaching occurred for cyanidin-3 galactoside and chokeberry colored solutions, with a decrease in half-lives from 22.8 to 0.3 days for Cyanidin-3-galactoside when 1000 mg/L AA was added. 5 Carboxypyranocyanidin-3-galactoside solution better maintained color with limited loss in absorbance, due to the formation of colored degradation products (lambdavis-max = 477 to 487 nm), and half-life decrease from 40.8 to 2.7 days, an 8-13-fold improvement compared to anthocyanins. This suggested alternative sites of reactivity with AA. Carbon-4 may be the preferred site for AA-pigment interactions, but it was not the only location. With Carbon-4 blocked, 5 Carboxypyranocyanidin-3-galactoside reacted with AA to form new pigments and reduce bleaching. PMID- 29570650 TI - A Review of Mechanoluminescence in Inorganic Solids: Compounds, Mechanisms, Models and Applications. AB - Mechanoluminescence (ML) is the non-thermal emission of light as a response to mechanical stimuli on a solid material. While this phenomenon has been observed for a long time when breaking certain materials, it is now being extensively explored, especially since the discovery of non-destructive ML upon elastic deformation. A great number of materials have already been identified as mechanoluminescent, but novel ones with colour tunability and improved sensitivity are still urgently needed. The physical origin of the phenomenon, which mainly involves the release of trapped carriers at defects with the help of stress, still remains unclear. This in turn hinders a deeper research, either theoretically or application oriented. In this review paper, we have tabulated the known ML compounds according to their structure prototypes based on the connectivity of anion polyhedra, highlighting structural features, such as framework distortion, layered structure, elastic anisotropy and microstructures, which are very relevant to the ML process. We then review the various proposed mechanisms and corresponding mathematical models. We comment on their contribution to a clearer understanding of the ML phenomenon and on the derived guidelines for improving properties of ML phosphors. Proven and potential applications of ML in various fields, such as stress field sensing, light sources, and sensing electric (magnetic) fields, are summarized. Finally, we point out the challenges and future directions in this active and emerging field of luminescence research. PMID- 29570651 TI - Unique Collagen Fibers for Biomedical Applications. AB - The challenge to develop grafts for tissue regeneration lies in the need to obtain a scaffold that will promote cell growth in order to form new tissue at a trauma-damaged site. Scaffolds also need to provide compatible mechanical properties that will support the new tissue and facilitate the desired physiological activity. Here, we used natural materials to develop a bio composite made of unique collagen embedded in an alginate hydrogel material. The collagen fibers used to create the building blocks exhibited a unique hyper elastic behavior similar to that of natural human tissue. The prominent mechanical properties, along with the support of cell adhesion affects cell shape and supports their proliferation, consequently facilitating the formation of a new tissue-like structure. The current study elaborates on these unique collagen fibers, focusing on their structure and biocompatibility, in an in vitro model. The findings suggest it as a highly appropriate material for biomedical applications. The promising in vitro results indicate that the distinctive collagen fibers could serve as a scaffold that can be adapted for tissue regeneration, in support of healing processes, along with maintaining tissue mechanical properties for the new regenerate tissue formation. PMID- 29570652 TI - GC-MS Based Metabolomics and NMR Spectroscopy Investigation of Food Intake Biomarkers for Milk and Cheese in Serum of Healthy Humans. AB - The identification and validation of food intake biomarkers (FIBs) in human biofluids is a key objective for the evaluation of dietary intake. We report here the analysis of the GC-MS and 1H-NMR metabolomes of serum samples from a randomized cross-over study in 11 healthy volunteers having consumed isocaloric amounts of milk, cheese, and a soy drink as non-dairy alternative. Serum was collected at baseline, postprandially up to 6 h, and 24 h after consumption. A multivariate analysis of the untargeted serum metabolomes, combined with a targeted analysis of candidate FIBs previously reported in urine samples from the same study, identified galactitol, galactonate, and galactono-1,5-lactone (milk), 3-phenyllactic acid (cheese), and pinitol (soy drink) as candidate FIBs for these products. Serum metabolites not previously identified in the urine samples, e.g., 3-hydroxyisobutyrate after cheese intake, were detected. Finally, an analysis of the postprandial behavior of candidate FIBs, in particular the dairy fatty acids pentadecanoic acid and heptadecanoic acid, revealed specific kinetic patterns of relevance to their detection in future validation studies. Taken together, promising candidate FIBs for dairy intake appear to be lactose and metabolites thereof, for lactose-containing products, and microbial metabolites derived from amino acids, for fermented dairy products such as cheese. PMID- 29570653 TI - Elucidating Adverse Nutritional Implications of Exposure to Endocrine-Disrupting Chemicals and Mycotoxins through Stable Isotope Techniques. AB - Multiple drivers of the double burden of malnutrition (DBM) include a rapid shift from predominantly plant-based diets to energy-dense foods based on meats, milk, animal fats and vegetable oils. The shift to overweight and obesity is driven by increased exposure to mass media, urbanization, technological advances in food processing, rising income and increased population density associated with increased access to cheap foods. At the same time, undernutrition persists mainly due to food insecurity and lack of access to safe water, sanitation and adequate health care. All known nutrition interventions result in only one third reduction in stunting. Little consideration has been given to hazardous exposure to endocrine disrupting chemicals (EDCs) and microbial toxins as major components of the malnutrition-causal framework. These hazards include microbial toxins, for example, mycotoxins, and environmental pollutants such as persistent organic pollutants (POPs), some of which are known to disrupt the endocrine system. These hazards sit at the cross road of undernutrition and overweight and obesity since the exposure cuts across the critical window of opportunity (the first 1000 days). In this review, we update on the role of food and environmental contaminants, especially EDCs and aflatoxins, in child growth and on the implications for metabolic dysfunction and disease risk in later life, and discuss potential applications of nuclear and isotopic techniques to elucidate the underlying biological mechanisms, outcome indicators, as well as occurrence levels.

AB - Babesia bigemina is one of the most prevalent species causing bovine babesiosis around the world. Antigens involved in host cell invasion are vaccine targets for this disease but are largely unknown in this species. The invasion process of Babesia spp. into erythrocytes involves membrane proteins from the apical complex. A protein stored in the micronemes, called Micronemal Protein 1 (MIC-1), contains a sialic acid binding domain that participates in the invasion process of host cells and is a vaccine candidate in other apicomplexan parasites. It is not known if there is a homologous gene for mic-1 in B. bigemina. Therefore, the aim of this study was to characterize the mic-1 gene homologue in Babesia bigemina. A gene was found with a microneme adhesive repeat (MAR) domain in the predicted amino acid sequence. Transcription was determined by reverse transcription polymerase chain reaction (RT-PCR). Subsequently, antibodies against peptides containing conserved B-cell epitopes were used to confirm the expression of MIC-1 in intraerythrocytic merozoites. The presence of anti MIC-1 antibodies in cattle naturally infected with B. bigemina was determined and up to 97.4% of the cattle sera (113 out of 116) identified MIC-1 using enzyme-linked immunosorbent assay (ELISA) methods. Finally, antibodies against MIC-1 were able to block 70% merozoite invasion in-vitro.

AB - The cattle tick, Rhipicephalus microplus (Canestrini), is an economically destructive arthropod because of its ability to vector bovine babesiosis. It is known that cattle ticks can spend 80-90% of their lifecycle as questing larvae, yet the effect of climatic factors on their off-host behavior and survival is unclear. The goal of this study was to measure the effects of specific ecological factors on off-host questing larvae in nature. The study was conducted in a south Texas pasture over a two-year period, during which time larval populations were surveyed. Simultaneously, weather variables-precipitation, relative humidity, and ambient temperatures-were recorded. Larval survival rates varied among seasons, with the overall highest populations recorded in the spring and the lowest in the fall by a ratio of 20:1. In the winter, the larger numbers were collected from exposed habitats at a ratio of 6:1. Conversely, canopied habitats in the summer had 10-fold larger larval numbers. In the spring, exposed and canopied habitats showed no difference in tick larval survival rates. The results show that the interaction between season and habitat strongly influence off-host questing tick survival. Relative humidity was a key weather variable.

AB - For the past two decades, veterinary educators have been at the forefront of innovations in educational practices related to science and medicine. Many of the resulting methods have been translated and implemented as best practices across the breadth of disciplines in higher education. However, past World Organization for Animal Health (OIE) global conferences have highlighted the necessity for improving global harmonization of veterinary medical education. This underscores a growing need for even broader dissemination of best practices and assessment programs related to educating our veterinary workforce. PMID- 29570657 TI - Operationalizing Principle-Based Standards for Animal Welfare-Indicators for Climate Problems in Pig Houses. AB - The Dutch animal welfare law includes so-called principle-based standards. This means that the objective is described in abstract terms, enabling farmers to comply with the law in their own way. Principle-based standards are, however, difficult for the inspection agency to enforce because strict limits are missing. This pilot project aimed at developing indicators (measurements) to assess the climate in pig houses, thus enabling the enforcement of principle-based standards. In total, 64 farms with weaners and 32 farms with growing-finishing pigs were visited. On each farm, a set of climate-related measurements was collected in six pens. For each of these measurements, a threshold value was set, and exceeding this threshold indicated a welfare risk. Farm inspections were carried out during winter and spring, thus excluding situations with heat stress. Assessment of the variation and correlation between measurements reduced the dataset from 39 to 12 measurements. Using a principal components analysis helped to select five major measurements as warning signals. The number of exceeded thresholds per pen and per farm was calculated for both the large (12) and small (five) sets of measurements. CO2 and NH3 concentrations were related to the outside temperature. On colder days, there was less ventilation, and thus CO2 and NH3 concentrations increased. Air quality, reflected in the CO2 and NH3 concentrations, was associated with respiratory problems. Eye scores were positively correlated with both pig and pen fouling, and pig and pen fouling were closely related. We selected five signal indicators: CO2, NH3, and tail and eye score for weaners and finishers, and added ear score for weaners and pig fouling for growing-finishing pigs. The results indicate that pig farms can be ranked based on five signal indicators related to reduced animal welfare caused by climatic conditions. This approach could be adopted to other principle-based standards for pigs as well as for other species. PMID- 29570658 TI - Mechanism of Mercury Adsorption and Oxidation by Oxygen over the CeO2 (111) Surface: A DFT Study. AB - CeO2 is a promising catalytic oxidation material for flue gas mercury removal. Density functional theory (DFT) calculations and periodic slab models are employed to investigate mercury adsorption and oxidation by oxygen over the CeO2 (111) surface. DFT calculations indicate that Hg0 is physically adsorbed on the CeO2 (111) surface and the Hg atom interacts strongly with the surface Ce atom according to the partial density of states (PDOS) analysis, whereas, HgO is adsorbed on the CeO2 (111) surface in a chemisorption manner, with its adsorption energy in the range of 69.9-198.37 kJ/mol. Depending on the adsorption methods of Hg0 and HgO, three reaction pathways (pathways I, II, and III) of Hg0 oxidation by oxygen are proposed. Pathway I is the most likely oxidation route on the CeO2 (111) surface due to it having the lowest energy barrier of 20.7 kJ/mol. The formation of the HgO molecule is the rate-determining step, which is also the only energy barrier of the entire process. Compared with energy barriers of Hg0 oxidation on the other catalytic materials, CeO2 is more efficient at mercury removal in flue gas owing to its low energy barrier. PMID- 29570660 TI - Effect of Par Frying on Composition and Texture of Breaded and Battered Catfish. AB - Catfish is often consumed as a breaded and battered fried product; however, there is increasing interest in breaded and battered baked products as a healthier alternative. Par frying can improve the texture properties of breaded and battered baked products, but there are concerns about the increase in lipid uptake from par frying. The objective of this study was to examine the effect of different batters (rice, corn, and wheat) and the effect of par frying on the composition and texture properties of baked catfish. Catfish fillets were cut strips and then coated with batters, which had similar viscosities. Half of the strips were par fried in 177 degrees C vegetable oil for 1 min and the other half were not par fried. Samples were baked at 177 degrees C for 25 min. Analysis included % batter adhesion, cooking loss, protein, lipid, ash, and moisture, plus hardness and fracture quality measured using a texture analyzer. A trained sensory panel evaluated both breading and flesh texture attributes. Results found the lipid content of par fried treatments were significantly higher for both corn and wheat batters than for non-par fried treatments. Sensory analysis indicated that the texture of the coatings in the par fried treatments were significantly greater for hardness attributes. Fillet flakiness was significantly greater in the par fried treatments and corn-based batters had moister fillet strips compared to the wheat flour batters. Texture analyzer hardness values were higher for the par fried treatments. PMID- 29570659 TI - Towards Improvements for Penetrating the Blood-Brain Barrier-Recent Progress from a Material and Pharmaceutical Perspective. AB - The blood-brain barrier (BBB) is a critical biological structure that prevents damage to the brain and maintains its bathing microenvironment. However, this barrier is also the obstacle to deliver beneficial drugs to treat CNS (central nervous system) diseases. Many efforts have been made for improvement of delivering drugs across the BBB in recent years to treat CNS diseases. In this review, the anatomical and functional structure of the BBB is comprehensively discussed. The mechanisms of BBB penetration are summarized, and the methods and effects on increasing BBB permeability are investigated in detail. It also elaborates on the physical, chemical, biological and nanocarrier aspects to improve drug delivery penetration to the brain and introduces some specific drug delivery effects on BBB permeability. PMID- 29570661 TI - How Long Are Cancer Patients Waiting for Oncological Therapy in Poland? AB - BACKGROUND: The five-year relative survival rate in Poland is approximately 10% lower compared with the average for Europe. One of the factors that may contribute to the inferior treatment results in Poland could be the long time between cancer suspicion and the beginning of treatment. The aim of the study was to determine the real waiting time for cancer diagnosis and treatment in Poland. METHODS: The study was carried out in six cancer centers on a group of 1373 patients, using a questionnaire to interview patients. The median waiting time was estimated as follows: (A) from suspicion (the date of the first visit, with symptoms, to a doctor or a preventive or screening test) until histopathological diagnosis; (B) from suspicion until initial treatment; and (C) from diagnosis until initial treatment. RESULTS: The median times from suspicion to treatment, from suspicion to diagnosis, and from diagnosis to treatment, were 10.6, 5.6, and 5.0 weeks, respectively. Using multivariate analysis, the strongest influence was estimated, in a case of tumor localization, to be the method of initial treatment and facilities. CONCLUSION: The waiting time for cancer treatment in Poland is too long. The highest influence on waiting time was determined, in the case of tumors, as the type of cancer and factors related to the health care system. PMID- 29570662 TI - Physical Practice and Wellness Courses Reduce Distress and Improve Wellbeing in Police Officers. AB - BACKGROUND: The aim of this work was to evaluate a course to reduce distress in an Italian police force. Based on the findings from the first investigations on this population, courses to improve the ability to manage distress were tailored by management. Several free courses were proposed, including physical efficiency (e.g., total body conditioning) and wellness (e.g., autogenic training) classes. The goal of this research was to evaluate the courses and their impact on the perceived distress and general health of the participants, as well as the effectiveness in increasing the use of adaptive coping strategies. METHODS: A descriptive investigation was conducted involving a sample of 105 police officers before (time 1) and after (time 2) they had participated in the courses. RESULTS: Findings confirmed both physical and wellness courses affected, in participants, the perceived distress, thereby increasing the perception of wellbeing. The participants expressed having mental health benefits, the use of adaptive coping strategies increased, while the maladaptive coping strategies decreased. CONCLUSION: This study confirms that these courses could effectively reduce the risk of chronic disease, a consequence of persistent exposure to distress. PMID- 29570663 TI - Investigating the Effect of Personality, Internet Literacy, and Use Expectancies in Internet-Use Disorder: A Comparative Study between China and Germany. AB - Research on Internet-use Disorder (IUD) has increased rapidly, indicating its clinical and global importance. Past studies suggested cultural diversity regarding the prevalence of an IUD, e.g., between Asian and European countries. Additionally, it was found that personality factors, Internet-related cognitions and specific competences seem to influence IUD tendencies, but research lacks in cultural comparative studies regarding these mechanisms. This study focuses on differences between Germany and China regarding the above-mentioned characteristics. German (n = 411; M = 20.70 years, SD = 3.34 years) and Chinese participants (n = 410; M = 20.72 years, SD = 2.65 years) answered the short Internet Addiction Test, Big Five Inventories, the Internet-use Expectancies Scale, as well as the Internet Literacy Questionnaire. The results revealed higher occurrence of IUD symptoms in China. Furthermore, Chinese participants scored significantly higher on neuroticism and agreeableness, whereas German participants scored higher on extraversion and openness. Compared to German participants, Chinese showed higher expectancies to avoid negative feelings online and to be positively reinforced. Regarding Internet literacy, German participants indicated higher skills concerning the reflection and critical analysis of online content, whereas Chinese showed higher expertise in producing and interacting online. Further, simple slope analyses indicated that certain Internet literacy domains were related differentially to IUD symptoms in Germany and China. While Chinese participants with higher reflective skills indicated highest IUD symptoms, reflective skills revealed no effect in Germany. Additionally, higher self-regulative skills correlated with lower IUD symptoms in the German, but not in the Chinese sample. The results give a hint to potential cultural differences regarding IUD, especially on the predictive and protective role of Internet literacy domains. PMID- 29570664 TI - Mortality and Morbidity during Extreme Heat Events and Prevalence of Outdoor Work: An Analysis of Community-Level Data from Los Angeles County, California. AB - Heat is a well-recognized hazard for workers in many outdoor settings, yet few investigations have compared the prevalence of outdoor work at the community level and rates of heat-related mortality and morbidity. This analysis examines whether heat-related health outcomes occur more frequently in communities with higher proportions of residents working in construction, agriculture, and other outdoor industries. Using 2005-2010 data from Los Angeles County, California, we analyze associations between community-level rates of deaths, emergency department (ED) visits, and hospitalizations during summer heat events and the prevalence of outdoor work. We find generally higher rates of heat-related ED visits and hospitalizations during summer heat events in communities with more residents working outdoors. Specifically, each percentage increase in residents working in construction resulted in an 8.1 percent increase in heat-related ED visits and a 7.9 percent increase in heat-related hospitalizations, while each percentage increase in residents working in agriculture and related sectors resulted in a 10.9 percent increase in heat-related ED visits. The findings suggest that outdoor work may significantly influence the overall burden of heat related morbidity at the community level. Public health professionals and healthcare providers should recognize work and employment as significant heat risk factors when preparing for and responding to extreme heat events. PMID- 29570666 TI - A Whole Germline BRCA2 Gene Deletion: How to Learn from CNV In Silico Analysis. AB - BRCA1/2 screening in Hereditary Breast and Ovarian Syndrome (HBOC) is an essential step for effective patients' management. Next-Generation Sequencing (NGS) can rapidly provide high throughput and reliable information about the qualitative and quantitative status of tumor-associated genes. Straightforwardly, bioinformatics methods play a key role in molecular diagnostics pipelines. BRCA1/2 genes were evaluated with our NGS workflow, coupled with Multiplex Amplicon Quantification (MAQ) and Multiplex Ligation-dependent Probe Amplification (MLPA) assays. Variant calling was performed on Amplicon Suite, while Copy Number Variant (CNV) prediction by in house and commercial CNV tools, before confirmatory MAQ/MLPA testing. The germline profile of BRCA genes revealed a unique HBOC pattern. Although variant calling analysis pinpointed heterozygote and homozygote polymorphisms on BRCA1 and BRCA2, respectively, the CNV predicted by our script suggested two conflicting interpretations: BRCA1 duplication and/or BRCA2 deletion. Our commercial software reported a BRCA1 duplication, in contrast with variant calling results. Finally, the MAQ/MLPA assays assessed a whole BRCA2 copy loss. In silico CNV analysis is a time and cost-saving procedure to powerfully identify possible Large Rearrangements using robust and efficient NGS pipelines. Our layout shows as bioinformatics algorithms alone cannot completely and correctly identify whole BRCA1/2 deletions/duplications. In particular, the complete deletion of an entire gene, like in our case, cannot be solved without alternative strategies as MLPA/MAQ. These findings support the crucial role of bioinformatics in deciphering pitfalls within NGS data analysis. PMID- 29570665 TI - Compressive Force Spectroscopy: From Living Cells to Single Proteins. AB - One of the most successful applications of atomic force microscopy (AFM) in biology involves monitoring the effect of force on single biological molecules, often referred to as force spectroscopy. Such studies generally entail the application of pulling forces of different magnitudes and velocities upon individual molecules to resolve individualistic unfolding/separation pathways and the quantification of the force-dependent rate constants. However, a less recognized variation of this method, the application of compressive force, actually pre-dates many of these "tensile" force spectroscopic studies. Further, beyond being limited to the study of single molecules, these compressive force spectroscopic investigations have spanned samples as large as living cells to smaller, multi-molecular complexes such as viruses down to single protein molecules. Correspondingly, these studies have enabled the detailed characterization of individual cell states, subtle differences between seemingly identical viral structures, as well as the quantification of rate constants of functionally important, structural transitions in single proteins. Here, we briefly review some of the recent achievements that have been obtained with compressive force spectroscopy using AFM and highlight exciting areas of its future development. PMID- 29570667 TI - Differential Tissue Fatty Acids Profiling between Colorectal Cancer Patients with and without Synchronous Metastasis. AB - The early detection of colorectal cancer and determination of its metastatic potential are important factors to set up more efficacious therapeutic strategies. In the present study, we hypothesize that fatty acids analysis in colorectal cancer patients can discriminate between metastatic and non-metastatic patients. Fifty-one consecutive patients with histologically proven colorectal cancer were enrolled in the study and the presence of synchronous metastasis was detected in 25 of these 51 patients. Fatty acid profile analysis in red blood cell membranes was not able to discriminate the metastatic colorectal cancer patients from those without metastasis. However, significant differences in the tumor tissue fatty acid profile were found in metastatic cancer patients when compared to patients without metastasis. Metastatic patients showed significantly lower percentages of Eicosapentaenoic acid (EPA) and higher levels of gamma linolenic acid (GLA), a n-3- and n-6-Polyunsaturated fatty acid (PUFA), respectively. Our findings, suggesting that membrane lipid rearrangement could influence the cellular function and make the cell more prone to metastasis, offer the opportunity to develop nutritional strategies that may be helpful in the prevention and treatment of colorectal cancer. PMID- 29570668 TI - Roles of Chloroplast Retrograde Signals and Ion Transport in Plant Drought Tolerance. AB - Worldwide, drought affects crop yields; therefore, understanding plants' strategies to adapt to drought is critical. Chloroplasts are key regulators of plant responses, and signals from chloroplasts also regulate nuclear gene expression during drought. However, the interactions between chloroplast initiated retrograde signals and ion channels under stress are still not clear. In this review, we summarise the retrograde signals that participate in regulating plant stress tolerance. We compare chloroplastic transporters that modulate retrograde signalling through retrograde biosynthesis or as critical components in retrograde signalling. We also discuss the roles of important plasma membrane and tonoplast ion transporters that are involved in regulating stomatal movement. We propose how retrograde signals interact with ion transporters under stress. PMID- 29570670 TI - Oxymatrine Inhibits Influenza A Virus Replication and Inflammation via TLR4, p38 MAPK and NF-kappaB Pathways. AB - Oxymatrine (OMT) is a strong immunosuppressive agent that has been used in the clinic for many years. In the present study, by using plaque inhibition, luciferase reporter plasmids, qRT-PCR, western blotting, and ELISA assays, we have investigated the effect and mechanism of OMT on influenza A virus (IAV) replication and IAV-induced inflammation in vitro and in vivo. The results showed that OMT had excellent anti-IAV activity on eight IAV strains in vitro. OMT could significantly decrease the promoter activity of TLR3, TLR4, TLR7, MyD88, and TRAF6 genes, inhibit IAV-induced activations of Akt, ERK1/2, p38 MAPK, and NF kappaB pathways, and suppress the expressions of inflammatory cytokines and MMP 2/-9. Activators of TLR4, p38 MAPK and NF-kappaB pathways could significantly antagonize the anti-IAV activity of OMT in vitro, including IAV replication and IAV-induced cytopathogenic effect (CPE). Furthermore, OMT could reduce the loss of body weight, significantly increase the survival rate of IAV-infected mice, decrease the lung index, pulmonary inflammation and lung viral titter, and improve pulmonary histopathological changes. In conclusion, OMT possesses anti IAV and anti-inflammatory activities, the mechanism of action may be linked to its ability to inhibit IAV-induced activations of TLR4, p38 MAPK, and NF-kappaB pathways. PMID- 29570671 TI - St. John's Wort Regulates Proliferation and Apoptosis in MCF-7 Human Breast Cancer Cells by Inhibiting AMPK/mTOR and Activating the Mitochondrial Pathway. AB - St. John's Wort (SJW) has been used as an estrogen agonist in the systems affected by menopause. Also, hypericin, a bioactive compound of SJW, has been used as a photosensitizer in photodynamic therapy. In the present study, we investigate the anti-proliferative and pro-apoptotic effects of SJW to demonstrate the chemo-preventive effect in human breast cancer cells. MCF-7 cells were cultured with DMSO or various concentrations of SJW ethanol extract (SJWE). Cell viability, proliferation, apoptosis, the expression of proteins involved in cell growth and apoptosis, and caspase-3/7 activity were examined. SJWE dose dependently suppressed cell growth and induced apoptosis of MCF-7 cells. Mechanistically, SJWE enhanced the phosphorylation of AMP-activated protein kinase (AMPK) and decreased the expression of p-mammalian target of rapamycin (p mTOR) and p-eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1). Also, SJWE inhibited the phosphorylation of protein kinase B (Akt) and showed increases in the expression of pro-apoptotic proteins Bax and Bad with decreases in the expression of anti-apoptotic proteins including B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xL), and p-Bcl-2-associated death promoter (p-Bad). SJWE at 50 MUg/mL showed markedly enhanced caspase-7 activation. Taken together, our results provide evidence that SJWE shows anti proliferative and pro-apoptotic effects via inhibition of AMPK/mTOR and activation of a mitochondrial pathway. Therefore, SJWE can be used as a chemo preventive agent without photo-activation. PMID- 29570669 TI - State-of-the-Art Fluorescence Fluctuation-Based Spectroscopic Techniques for the Study of Protein Aggregation. AB - Neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Alzheimer's disease, Parkinson's disease, and Huntington's disease, are devastating proteinopathies with misfolded protein aggregates accumulating in neuronal cells. Inclusion bodies of protein aggregates are frequently observed in the neuronal cells of patients. Investigation of the underlying causes of neurodegeneration requires the establishment and selection of appropriate methodologies for detailed investigation of the state and conformation of protein aggregates. In the current review, we present an overview of the principles and application of several methodologies used for the elucidation of protein aggregation, specifically ones based on determination of fluctuations of fluorescence. The discussed methods include fluorescence correlation spectroscopy (FCS), imaging FCS, image correlation spectroscopy (ICS), photobleaching ICS (pbICS), number and brightness (N&B) analysis, super-resolution optical fluctuation imaging (SOFI), and transient state (TRAST) monitoring spectroscopy. Some of these methodologies are classical protein aggregation analyses, while others are not yet widely used. Collectively, the methods presented here should help the future development of research not only into protein aggregation but also neurodegenerative diseases. PMID- 29570672 TI - Impact of the NO-Sensitive Guanylyl Cyclase 1 and 2 on Renal Blood Flow and Systemic Blood Pressure in Mice. AB - Nitric oxide (NO) modulates renal blood flow (RBF) and kidney function and is involved in blood pressure (BP) regulation predominantly via stimulation of the NO-sensitive guanylyl cyclase (NO-GC), existing in two isoforms, NO-GC1 and NO GC2. Here, we used isoform-specific knockout (KO) mice and investigated their contribution to renal hemodynamics under normotensive and angiotensin II-induced hypertensive conditions. Stimulation of the NO-GCs by S-nitrosoglutathione (GSNO) reduced BP in normotensive and hypertensive wildtype (WT) and NO-GC2-KO mice more efficiently than in NO-GC1-KO. NO-induced increase of RBF in normotensive mice did not differ between the genotypes, but the respective increase under hypertensive conditions was impaired in NO-GC1-KO. Similarly, inhibition of endogenous NO increased BP and reduced RBF to a lesser extent in NO-GC1-KO than in NO-GC2-KO. These findings indicate NO-GC1 as a target of NO to normalize RBF in hypertension. As these effects were not completely abolished in NO-GC1-KO and renal cyclic guanosine monophosphate (cGMP) levels were decreased in both NO-GC1 KO and NO-GC2-KO, the results suggest an additional contribution of NO-GC2. Hence, NO-GC1 plays a predominant role in the regulation of BP and RBF, especially in hypertension. However, renal NO-GC2 appears to compensate the loss of NO-GC1, and is able to regulate renal hemodynamics under physiological conditions. PMID- 29570673 TI - Protective Effects of Gomisin N against Hepatic Cannabinoid Type 1 Receptor Induced Insulin Resistance and Gluconeogenesis. AB - Activation of the hepatic cannabinoid type 1 receptor (CB1R) induces insulin resistance and gluconeogenesis via endoplasmic reticulum (ER) stress, thereby contributing to hyperglycemia. Gomisin N (GN) is a phytochemical derived from Schisandra chinensis. In the current study, we investigated the inhibitory effects of GN on hepatic CB1R-mediated insulin resistance and gluconeogenesis in 2-arachidonoylglycerol (AG; an agonist of CB1R)-treated HepG2 cells and in high fat diet (HFD)-induced obese mice. Treatment with 2-AG induced the expression of ER stress markers, serine/threonine phosphatase PHLPP1, Lipin1, and ceramide synthesis genes, but reduced the expression of ceramide degradation genes in HepG2 cells. However, GN reversed 2-AG-mediated effects and improved the 2-AG mediated impairment of insulin signaling. Furthermore, GN inhibited 2-AG-induced intracellular triglyceride accumulation and glucose production in HepG2 cells by downregulation of lipogenesis and gluconeogenesis genes, respectively. In vivo, GN administration to HFD obese mice reduced the HFD-induced increase in fasting blood glucose and insulin levels, which was accompanied with downregulation of HFD-induced expression of CB1R, ER stress markers, ceramide synthesis gene, and gluconeogenesis genes in the livers of HFD obese mice. These findings demonstrate that GN protects against hepatic CB1-mediated impairment of insulin signaling and gluconeogenesis, thereby contributing to the amelioration of hyperglycemia. PMID- 29570674 TI - PER, a Circadian Clock Component, Mediates the Suppression of MMP-1 Expression in HaCaT Keratinocytes by cAMP. AB - Skin circadian clock system responds to daily changes, thereby regulating skin functions. Exposure of the skin to UV irradiation induces the expression of matrix metalloproteinase-1 (MMP-1) and causes DNA damage. It has been reported both DNA repair and DNA replication are regulated by the circadian clock in mouse skin. However, the molecular link between circadian clock and MMP-1 has little been investigated. We found PERIOD protein, a morning clock component, represses the expression of MMP-1 in human keratinocytes by using a PER-knockdown strategy. Treatment with siPer3 alleviated the suppression of MMP-1 expression induced by forskolin. Results revealed PER3 suppresses the expression of MMP-1 via cAMP signaling pathway. Additionally, we screened for an activator of PER that could repress the expression of MMP-1 using HaCaT cell line containing PER promoter luciferase reporter gene. Results showed Lespedeza capitate extract (LCE) increased PER promoter activity. LCE inhibited the expression of MMP-1 and its effect of LCE was abolished in knockdown of PER2 or PER3, demonstrating LCE can repress the expression of MMP-1 through PER. Since circadian clock component PER can regulate MMP-1 expression, it might be a new molecular mechanism to develop therapeutics to alleviate skin aging and skin cancer. PMID- 29570676 TI - Supporting Beacon and Event-Driven Messages in Vehicular Platoons through Token Based Strategies. AB - Timely and reliable inter-vehicle communications is a critical requirement to support traffic safety applications, such as vehicle platooning. Furthermore, low delay communications allow the platoon to react quickly to unexpected events. In this scope, having a predictable and highly effective medium access control (MAC) method is of utmost importance. However, the currently available IEEE 802.11p technology is unable to adequately address these challenges. In this paper, we propose a MAC method especially adapted to platoons, able to transmit beacons within the required time constraints, but with a higher reliability level than IEEE 802.11p, while concurrently enabling efficient dissemination of event-driven messages. The protocol circulates the token within the platoon not in a round robin fashion, but based on beacon data age, i.e., the time that has passed since the previous collection of status information, thereby automatically offering repeated beacon transmission opportunities for increased reliability. In addition, we propose three different methods for supporting event-driven messages co-existing with beacons. Analysis and simulation results in single and multi-hop scenarios showed that, by providing non-competitive channel access and frequent retransmission opportunities, our protocol can offer beacon delivery within one beacon generation interval while fulfilling the requirements on low-delay dissemination of event-driven messages for traffic safety applications. PMID- 29570675 TI - An Arabidopsis Clathrin Assembly Protein with a Predicted Role in Plant Defense Can Function as an Adenylate Cyclase. AB - Adenylate cyclases (ACs), much like guanylate cyclases (GCs), are increasingly recognized as essential parts of many plant processes including biotic and abiotic stress responses. In order to identify novel ACs, we have applied a search motif derived from experimentally tested GCs and identified a number of Arabidopsis thaliana candidates including a clathrin assembly protein (AT1G68110; AtClAP). AtClAP contains a catalytic centre that can complement the AC-deficient mutant cyaA in E. coli, and a recombinant AtClAP fragment (AtClAP261-379) can produce cyclic adenosine 3',5' monophosphate (cAMP) from adenosine triphosphate (ATP) in vitro. Furthermore, an integrated analysis of gene expression and expression correlation implicate cAMP in pathogen defense and in actin cytoskeletal remodeling during endocytic internalization. PMID- 29570677 TI - Gas Sensing Properties of p-Co3O4/n-TiO2 Nanotube Heterostructures. AB - In this paper, we fabricated p-Co3O4/n-TiO2 heterostructures and investigated their gas sensing properties. The structural and morphological characterization were performed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy analysis (XPS). The electrical properties of the heterostructure were studied within the temperature range from 293 K to 423 K. Changes in electrical properties and sensing behavior against reducing and oxidizing gases were attributed to the formation of p-n heterojunctions at the Co3O4 and TiO2 interface. In comparison with sensing performed with pristine TiO2 nanotubes (NTs), a significant improvement in H2 sensing at 200 degrees C was observed, while the sensing response against NO2 decreased for the heterostructures. Additionally, a response against toluene gas, in contrast to pristine TiO2 NTs, appeared in the Co3O4/TiO2 heterostructure samples. PMID- 29570678 TI - Convolutional Neural Network-Based Classification of Driver's Emotion during Aggressive and Smooth Driving Using Multi-Modal Camera Sensors. AB - Because aggressive driving often causes large-scale loss of life and property, techniques for advance detection of adverse driver emotional states have become important for the prevention of aggressive driving behaviors. Previous studies have primarily focused on systems for detecting aggressive driver emotion via smart-phone accelerometers and gyro-sensors, or they focused on methods of detecting physiological signals using electroencephalography (EEG) or electrocardiogram (ECG) sensors. Because EEG and ECG sensors cause discomfort to drivers and can be detached from the driver's body, it becomes difficult to focus on bio-signals to determine their emotional state. Gyro-sensors and accelerometers depend on the performance of GPS receivers and cannot be used in areas where GPS signals are blocked. Moreover, if driving on a mountain road with many quick turns, a driver's emotional state can easily be misrecognized as that of an aggressive driver. To resolve these problems, we propose a convolutional neural network (CNN)-based method of detecting emotion to identify aggressive driving using input images of the driver's face, obtained using near-infrared (NIR) light and thermal camera sensors. In this research, we conducted an experiment using our own database, which provides a high classification accuracy for detecting driver emotion leading to either aggressive or smooth (i.e., relaxed) driving. Our proposed method demonstrates better performance than existing methods. PMID- 29570679 TI - Electrochemical Aptasensors for Food and Environmental Safeguarding: A Review. AB - Food and environmental monitoring is one of the most important aspects of dealing with recent threats to human well-being and ecosystems. In this framework, electrochemical aptamer-based sensors are resilient due to their ability to resolve food and environmental contamination. An aptamer-based sensor is a compact analytical device combining an aptamer as the bio-sensing element integrated on the transducer surface. Aptamers display many advantages as biorecognition elements in sensor development when compared to affinity-based (antibodies) sensors. Aptasensors are small, chemically unchanging, and inexpensive. Moreover, they offer extraordinary elasticity and expediency in the design of their assemblies, which has led to innovative sensors that show tremendous sensitivity and selectivity. This review will emphasize recent food and environmental safeguarding using aptasensors; there are good prospects for their performance as a supplement to classical techniques. PMID- 29570680 TI - A Highly Thermostable In2O3/ITO Thin Film Thermocouple Prepared via Screen Printing for High Temperature Measurements. AB - An In2O3/ITO thin film thermocouple was prepared via screen printing. Glass additives were added to improve the sintering process and to increase the density of the In2O3/ITO films. The surface and cross-sectional images indicate that both the grain size and densification of the ITO and In2O3 films increased with the increase in annealing time. The thermoelectric voltage of the In2O3/ITO thermocouple was 53.5 mV at 1270 degrees C at the hot junction. The average Seebeck coefficient of the thermocouple was calculated as 44.5 MUV/ degrees C. The drift rate of the In2O3/ITO thermocouple was 5.44 degrees C/h at a measuring time of 10 h at 1270 degrees C. PMID- 29570682 TI - Resistance to 6-Methylpurine is Conferred by Defective Adenine Phosphoribosyltransferase in Tetrahymena. AB - 6-methylpurine (6mp) is a toxic analog of adenine that inhibits RNA and protein synthesis and interferes with adenine salvage mediated by adenine phosphoribosyltransferase (APRTase). Mutants of the ciliated protist Tetrahymena thermophila that are resistant to 6mp were isolated in 1974, but the mechanism of resistance has remained unknown. To investigate 6mp resistance in T. thermophila, we created 6mp-resistant strains and identified a mutation in the APRTase genomic locus (APRT1) that is responsible for 6mp resistance. While overexpression of the mutated APRT1 allele in 6mp-sensitive cells did not confer resistance to 6mp, reduced wild-type APRT1 expression resulted in a significant decrease in sensitivity to 6mp. Knocking out or reducing the expression of APRT1 by RNA interference (RNAi) did not affect robust cell growth, which indicates that adenine salvage is redundant or that de novo synthesis pathways provide sufficient adenosine monophosphate for viability. We also explored whether 6mp resistance could be used as a novel inducible selection marker by generating 6mp- and paromomycin-resistant double mutants. While 6mp- and paromomycin-resistant double mutants did express fluorescent proteins in an RNAi-based system, the system requires optimization before 6mp resistance can be used as an effective inducible selection marker.

AB - The kinetics of polyphenol extraction from brewer's spent grain (BSG), using a batch system, ultrasound assistance, and microwave assistance and the evolution of antioxidant capacity of these extracts over time, were studied. The main parameters of extraction employed in the batch system were evaluated, and, by applying response surface analysis, the following optimal conditions were obtained: Liquid/solid ratio of 30:1 mL/g at 80 degrees C, using 72% (v/v) ethanol:water as the solvent system. Under these optimized conditions, ultrasound assistance demonstrated the highest extraction rate and equilibrium yield, as well as shortest extraction times, followed by microwave assistance. Among the mathematical models used, Patricelli's model proved the most suitable for describing the extraction kinetics for each method tested, and is therefore able to predict the response values and estimate the extraction rates and potential maximum yields in each case. PMID- 29570684 TI - Sensor-Based Optimization Model for Air Quality Improvement in Home IoT. AB - We introduce current home Internet of Things (IoT) technology and present research on its various forms and applications in real life. In addition, we describe IoT marketing strategies as well as specific modeling techniques for improving air quality, a key home IoT service. To this end, we summarize the latest research on sensor-based home IoT, studies on indoor air quality, and technical studies on random data generation. In addition, we develop an air quality improvement model that can be readily applied to the market by acquiring initial analytical data and building infrastructures using spectrum/density analysis and the natural cubic spline method. Accordingly, we generate related data based on user behavioral values. We integrate the logic into the existing home IoT system to enable users to easily access the system through the Web or mobile applications. We expect that the present introduction of a practical marketing application method will contribute to enhancing the expansion of the home IoT market. PMID- 29570685 TI - Synthesis, Characterization, and Antifungal Activity of Novel Benzo[4,5]imidazo[1,2-d][1,2,4]triazine Derivatives. AB - A series of novel fused heterocyclic compounds bearing benzo[4,5]imidazo[1,2 d][1,2,4]triazine 4a-4w were designed and conveniently synthesized via the intermediates 2-(halogenated alkyl)-1H-benzo[d]imidazoles 2a, 2b, and 2-((1 (substituted phenyl)hydrazinyl)alkyl)-1H-benzo[d]imidazoles 3a-3g. The structures of all target compounds were characterized by FT-IR, 1H NMR, 13C NMR, and EI-MS, of which, the structure of compound 4n was further determined by the single crystal X-ray diffraction. The crystal structure of 4n was crystallized in the triclinic crystal system, space group P 1 - with a = 9.033 (6) A, b = 10.136 (7) A, c = 10.396 (7) A, alpha = 118.323 (7) degrees , beta = 91.750 (8) degrees , gamma = 104.198 (7) degrees , Z = 2, V = 800.2 (9) A3; total R indices: R1 = 0.0475, wR2 = 0.1284. The antifungal activity of title compounds 4a-4w in vitro against the phytopathogenic fungi Botrytis cinerea (B. cinerea), Rhizoctonia solani (R. solani) and Colletotrichum capsici (C. capsici) were evaluated, the bioassay results demonstrated that most of the title compounds exhibited obvious fungicidal activities at 50 MUg/mL. This work indicated that benzo[4,5]imidazo[1,2-d][1,2,4]triazine derivatives could be considered as a new leading structure in searching for novel agricultural fungicides. PMID- 29570686 TI - Design, Synthesis, and Biological Evaluation of Axitinib Derivatives. AB - Axitinib is an approved kinase inhibitor for the therapy of advanced metastatic renal cell carcinoma (RCC). It prevents angiogenesis, cellular adhesion, and induces apoptosis of cancer cells. Here, nine axitinib derivatives were designed by replacing the C=C moiety with the N=N group, and the substituted benzene or pyrrole analogs were considered to replace the pyridine ring. Biological activity results showed that most of nascent derivatives exhibited favorable VEGFR-2 kinase inhibitory activities, and TM6, 7, 9, and 11 behaved more potent anti proliferative activities than axitinib. This novel series of compounds shows a potential for the treatment of solid tumors and other diseases where angiogenesis plays an important role. PMID- 29570687 TI - Scaling-Up the Impact of Aflatoxin Research in Africa. The Role of Social Sciences. AB - At the interface between agriculture and nutrition, the aflatoxin contamination of food and feed touches on agriculture, health, and trade. For more than three decades now, the problem of aflatoxin has been researched in Africa. The interest of development cooperation for aflatoxin and the support to aflatoxin mitigation projects has its ups and downs. The academic world and the development world still seem to operate in different spheres and a collaboration is still challenging due to the complexity of the contamination sources at pre-harvest and post-harvest levels. There is a growing call by research funders and development actors for the impact of solutions at a scale. The solutions to mitigate aflatoxin contamination require new ways of working together. A more prominent role is to be played by social scientists. The role of social scientists in scaling-up the impact of aflatoxin research in Africa and the proposed mitigation solutions is to ensure that awareness, advantage, affordability, and access are systematically assessed. Aflatoxin-reduced staple foods and feed would be an agricultural result with a considerable health and food safety impact. PMID- 29570681 TI - Wnt Signalling in Gastrointestinal Epithelial Stem Cells. AB - Wnt signalling regulates several cellular functions including proliferation, differentiation, apoptosis and migration, and is critical for embryonic development. Stem cells are defined by their ability for self-renewal and the ability to be able to give rise to differentiated progeny. Consequently, they are essential for the homeostasis of many organs including the gastrointestinal tract. This review will describe the huge advances in our understanding of how stem cell functions in the gastrointestinal tract are regulated by Wnt signalling, including how deregulated Wnt signalling can hijack these functions to transform cells and lead to cancer. PMID- 29570690 TI - Convolutional Neural Network-Based Shadow Detection in Images Using Visible Light Camera Sensor. AB - Recent developments in intelligence surveillance camera systems have enabled more research on the detection, tracking, and recognition of humans. Such systems typically use visible light cameras and images, in which shadows make it difficult to detect and recognize the exact human area. Near-infrared (NIR) light cameras and thermal cameras are used to mitigate this problem. However, such instruments require a separate NIR illuminator, or are prohibitively expensive. Existing research on shadow detection in images captured by visible light cameras have utilized object and shadow color features for detection. Unfortunately, various environmental factors such as illumination change and brightness of background cause detection to be a difficult task. To overcome this problem, we propose a convolutional neural network-based shadow detection method. Experimental results with a database built from various outdoor surveillance camera environments, and from the context-aware vision using image-based active recognition (CAVIAR) open database, show that our method outperforms previous works. PMID- 29570689 TI - Association between Maternal and Foetal Erythrocyte Fatty Acid Profiles and Birth Weight. AB - Regular foetal development is crucial for assuring good health status in the offspring. The quality and quantity of maternal dietary fatty acids (FAs) can affect growth. The study aimed to: (1) investigate the association of maternal/foetal lipid profiles with birth weight (BW); and (2) compare these profiles in small, appropriate, and large for gestational age (SGA, AGA, and LGA) infants. FAs were measured in erythrocyte membranes using gas chromatography analysis in 607 mother-infant pairs (316 males, 52.1%). In the quantile regression, a significant association between BW and levels of maternal linoleic acid (LA; C18:2, n-6; coefficient: 18.66; p = 0.010), arachidonic acid (AA; C20:4, n-6; coefficient: 11.35; p = 0.007), docosahexaenoic acid (DHA; C22:6, n 3; coefficient: 29.73; p = 0.007), polyunsaturated FAs (coefficient: 8.55; p = 0.001), foetal DHA (coefficient: -22.82; p = 0.037), and saturated FAs (coefficient: -65.41; p = 0.002) was found. Myristic (C14:0) and pentadecanoic acids (C15:0), both maternal (p = 0.000; p = 0.017) and foetal (p = 0.009; p = 0.002), and maternal erucic acid (C22:1, n-9; p = 0.026) were found at higher levels in SGA infants as compared to AGA ones. Conversely, maternal LA, AA, and omega 6 FAs levels were higher in AGA infants (p = 0.037; p = 0.003; p = 0.026, respectively). Maternal and foetal polyunsaturated and omega 6 FAs levels are positively related to BW, while a lipid profile rich in saturated FAs and erucic acid may influence the risk of SGA. PMID- 29570691 TI - A Multi-Hop Clustering Mechanism for Scalable IoT Networks. AB - It is expected that up to 26 billion Internet of Things (IoT) equipped with sensors and wireless communication capabilities will be connected to the Internet by 2020 for various purposes. With a large scale IoT network, having each node connected to the Internet with an individual connection may face serious scalability issues. The scalability problem of the IoT network may be alleviated by grouping the nodes of the IoT network into clusters and having a representative node in each cluster connect to the Internet on behalf of the other nodes in the cluster instead of having a per-node Internet connection and communication. In this paper, we propose a multi-hop clustering mechanism for IoT networks to minimize the number of required Internet connections. Specifically, the objective of proposed mechanism is to select the minimum number of coordinators, which take the role of a representative node for the cluster, i.e., having the Internet connection on behalf of the rest of the nodes in the cluster and to map a partition of the IoT nodes onto the selected set of coordinators to minimize the total distance between the nodes and their respective coordinator under a certain constraint in terms of maximum hop count between the IoT nodes and their respective coordinator. Since this problem can be mapped into a set cover problem which is known as NP-hard, we pursue a heuristic approach to solve the problem and analyze the complexity of the proposed solution. Through a set of experiments with varying parameters, the proposed scheme shows 63-87.3% reduction of the Internet connections depending on the number of the IoT nodes while that of the optimal solution is 65.6-89.9% in a small scale network. Moreover, it is shown that the performance characteristics of the proposed mechanism coincide with expected performance characteristics of the optimal solution in a large scale network. PMID- 29570688 TI - Diagnosis, Evaluation and Treatment of Pulmonary Arterial Hypertension in Children. AB - Pulmonary Hypertension (PH), the syndrome of elevated pressure in the pulmonary arteries, is associated with significant morbidity and mortality for affected children. PH is associated with a wide variety of potential underlying causes, including cardiac, pulmonary, hematologic and rheumatologic abnormalities. Regardless of the cause, for many patients the natural history of PH involves progressive elevation in pulmonary arterial resistance and pressure, right ventricular dysfunction, and eventually heart failure. In recent years, a number of pulmonary arterial hypertension (PAH)-targeted therapies have become available to reduce pulmonary artery pressure and improve outcome. A growing body of evidence in both the adult and pediatric literature demonstrates enhanced quality of life, functional status, and survival among treated patients. This review provides a description of select etiologies of PH seen in pediatrics and an update on the most recent data pertaining to evaluation and management of children with PH/PAH. The available evidence for specific classes of PAH-targeted therapies in pediatrics is additionally discussed. PMID- 29570692 TI - Preclinical Evaluation of Vemurafenib as Therapy for BRAFV600E Mutated Sarcomas. AB - : The BRAFV600E mutation, which in melanoma is targetable with vemurafenib, is also found in sarcomas and we here evaluate the therapeutic potential in sarcoma cell lines. METHODS: Four sarcoma cell lines harboring the BRAFV600E mutation, representing liposarcomas (SA-4 and SW872), Ewing sarcoma (A673) and atypical synovial sarcoma (SW982), were treated with vemurafenib and the effects on cell growth, apoptosis, cell cycle progression and cell signaling were determined. RESULTS: Vemurafenib induced a strong cytostatic effect in SA-4 cells, mainly due to cell cycle arrest, whereas only moderate levels of apoptosis were observed. However, a high dose was required compared to BRAFV600E mutated melanoma cells, and removal of vemurafenib demonstrated that the continuous presence of drug was required for sustained growth inhibition. A limited growth inhibition was observed in the other three cell lines. Protein analyses demonstrated reduced phosphorylation of ERK during treatment with vemurafenib in all the four sarcoma cell lines confirming that the MAPK pathway is active in these cell lines, and that the pathway can be inhibited by vemurafenib, but also that these cells can proliferate despite this. CONCLUSIONS: These findings indicate that vemurafenib alone would not be an efficient therapy against BRAFV600E mutated sarcomas. However, further investigations of combination with other drugs are warranted. PMID- 29570693 TI - Clearing Extracellular Alpha-Synuclein from Cerebrospinal Fluid: A New Therapeutic Strategy in Parkinson's Disease. AB - This concept article aims to show the rationale of targeting extracellular alpha Synuclein (alpha-Syn) from cerebrospinal fluid (CSF) as a new strategy to remove this protein from the brain in Parkinson's disease (PD). Misfolding and intracellular aggregation of alpha-synuclein into Lewy bodies are thought to be crucial in the pathogenesis of PD. Recent research has shown that small amounts of monomeric and oligomeric alpha-synuclein are released from neuronal cells by exocytosis and that this extracellular alpha-synuclein contributes to neurodegeneration, progressive spreading of alpha-synuclein pathology, and neuroinflammation. In PD, extracellular oligomeric-alpha-synuclein moves in constant equilibrium between the interstitial fluid (ISF) and the CSF. Thus, we expect that continuous depletion of oligomeric-alpha-synuclein in the CSF will produce a steady clearance of the protein in the ISF, preventing transmission and deposition in the brain. PMID- 29570695 TI - Lack of Substantial Post-Cessation Weight Increase in Electronic Cigarettes Users. AB - Minimization of post-cessation weight gain in quitters is important, but existing approaches (e.g., antismoking medications) shows only limited success. We investigated changes in body weight in smokers who quit or reduced substantially their cigarette consumption by switching to electronic cigarettes (ECs) use. Body weight and smoking/vaping history were extracted from medical records of smokers and ex-smokers to match three study groups: (1) regular EC users on at least two consecutive follow-up visits; (2) regular smokers (and not using ECs); (3) subjects who reported sustained smoking abstinence after completing a cessation program. Review of their medical records was conducted at two follow-up visits at 6- (F/U 6m) and 12-months (F/U 12m). A total of 86 EC users, 93 regular smokers, and 44 quitters were studied. In the EC users study group, cigarettes/day use decreased from 21.1 at baseline to 1.8 at F/U 12m (p < 0.0001). Dual usage was reported by approximately 50% of EC users. Both within factor (time, p < 0.0001) and between factor (study groups, p < 0.0001) produced significant effect on weight (% change from baseline), with a significant 4.8% weight gain from baseline in the quitters study group at F/U 12m. For the EC users, weight gain at F/U 12m was only 1.5% of baseline. There was no evidence of post-cessation weight increase in those who reduced substantially cigarette consumption by switching to ECs (i.e., dual users) and only modest post-cessation weight increase was reported in exclusive EC users at F/U 12m. By reducing weight gain and tobacco consumption, EC-based interventions may promote an overall improvement in quality of life. PMID- 29570696 TI - Patternable Poly(chloro-p-xylylene) Film with Tunable Surface Wettability Prepared by Temperature and Humidity Treatment on a Polydimethylsiloxane/Silica Coating. AB - Poly(chloro-p-xylylene) (PPXC) film has a water contact angle (WCA) of only about 84 degrees . It is necessary to improve its hydrophobicity to prevent liquid water droplets from corroding or electrically shorting metallic circuits of semiconductor devices, sensors, microelectronics, and so on. Herein, we reported a facile approach to improve its surface hydrophobicity by varying surface pattern structures under different temperature and relative humidity (RH) conditions on a thermal curable polydimethylsiloxane (PDMS) and hydrophobic silica (SiO2) nanoparticle coating. Three distinct large-scale surface patterns were obtained mainly depending on the contents of SiO2 nanoparticles. The regularity of patterns was mainly controlled by the temperature and RH conditions. By changing the pattern structures, the surface wettability of PPXC film could be improved and its WCA was increased from 84 degrees to 168 degrees , displaying a superhydrophobic state. Meanwhile, it could be observed that water droplets on PPXC film with superhydrophobicity were transited from a "Wenzel" state to a "Cassie" state. The PPXC film with different surface patterns of 200 MUm * 200 MUm and the improved surface hydrophobicity showed wide application potentials in self-cleaning, electronic engineering, micro-contact printing, cell biology, and tissue engineering. PMID- 29570698 TI - Sensor Fusion to Estimate the Depth and Width of the Weld Bead in Real Time in GMAW Processes. AB - The arc welding process is widely used in industry but its automatic control is limited by the difficulty in measuring the weld bead geometry and closing the control loop on the arc, which has adverse environmental conditions. To address this problem, this work proposes a system to capture the welding variables and send stimuli to the Gas Metal Arc Welding (GMAW) conventional process with a constant voltage power source, which allows weld bead geometry estimation with an open-loop control. Dynamic models of depth and width estimators of the weld bead are implemented based on the fusion of thermographic data, welding current and welding voltage in a multilayer perceptron neural network. The estimators were trained and validated off-line with data from a novel algorithm developed to extract the features of the infrared image, a laser profilometer was implemented to measure the bead dimensions and an image processing algorithm that measures depth by making a longitudinal cut in the weld bead. These estimators are optimized for embedded devices and real-time processing and were implemented on a Field-Programmable Gate Array (FPGA) device. Experiments to collect data, train and validate the estimators are presented and discussed. The results show that the proposed method is useful in industrial and research environments. PMID- 29570697 TI - DNA Damage, Mutagenesis and Cancer. AB - A large number of chemicals and several physical agents, such as UV light and gamma-radiation, have been associated with the etiology of human cancer. Generation of DNA damage (also known as DNA adducts or lesions) induced by these agents is an important first step in the process of carcinogenesis. Evolutionary processes gave rise to DNA repair tools that are efficient in repairing damaged DNA; yet replication of damaged DNA may take place prior to repair, particularly when they are induced at a high frequency. Damaged DNA replication may lead to gene mutations, which in turn may give rise to altered proteins. Mutations in an oncogene, a tumor-suppressor gene, or a gene that controls the cell cycle can generate a clonal cell population with a distinct advantage in proliferation. Many such events, broadly divided into the stages of initiation, promotion, and progression, which may occur over a long period of time and transpire in the context of chronic exposure to carcinogens, can lead to the induction of human cancer. This is exemplified in the long-term use of tobacco being responsible for an increased risk of lung cancer. This mini-review attempts to summarize this wide area that centers on DNA damage as it relates to the development of human cancer. PMID- 29570694 TI - Enteric Virome Sensing-Its Role in Intestinal Homeostasis and Immunity. AB - Pattern recognition receptors (PRRs) sensing commensal microorganisms in the intestine induce tightly controlled tonic signaling in the intestinal mucosa, which is required to maintain intestinal barrier integrity and immune homeostasis. At the same time, PRR signaling pathways rapidly trigger the innate immune defense against invasive pathogens in the intestine. Intestinal epithelial cells and mononuclear phagocytes in the intestine and the gut-associated lymphoid tissues are critically involved in sensing components of the microbiome and regulating immune responses in the intestine to sustain immune tolerance against harmless antigens and to prevent inflammation. These processes have been mostly investigated in the context of the bacterial components of the microbiome so far. The impact of viruses residing in the intestine and the virus sensors, which are activated by these enteric viruses, on intestinal homeostasis and inflammation is just beginning to be unraveled. In this review, we will summarize recent findings indicating an important role of the enteric virome for intestinal homeostasis as well as pathology when the immune system fails to control the enteric virome. We will provide an overview of the virus sensors and signaling pathways, operative in the intestine and the mononuclear phagocyte subsets, which can sense viruses and shape the intestinal immune response. We will discuss how these might interact with resident enteric viruses directly or in context with the bacterial microbiome to affect intestinal homeostasis. PMID- 29570699 TI - MicroRNA-194 Regulates the Development and Differentiation of Sensory Patches and Statoacoustic Ganglion of Inner Ear by Fgf4. AB - BACKGROUND MicroRNA 194 is involved in the differentiation of various types of cells, such as adipose derived stem cells, human embryonic stem cells, and bone marrow mesenchymal stem cells. Previously, we found that miR-194 was highly expressed in the inner ear sensory patch and neurons in mice embryos. However, the role of miR-194 in the development of the inner ear and its underlying mechanism have not been elucidated yet. MATERIAL AND METHODS The expression level of miR-194 has been altered by using antisense morpholino oligonucleotides (MO) and synthesized miRNAs in zebrafish. RESULTS We found that miR-194 was vastly expressed in the inner ear and central nervous system (CNS) in zebrafish. Loss of function of miR-194 could strongly affected the development of zebrafish embryos, including delayed embryonic development, edema of the pericardium, small head, axial deviation, delayed development of inner ear, closer location of two otoliths, delayed fusion of the semicircular canals, and abnormal otolith number in some cases. In addition, the behavior of zebrafish was also adversely affected with impaired balance and biased swimming route. Misexpression of miR-194 could strongly affected the development and differentiation of spiral ganglion neuron (SGN) in inner ear through Fgf4 in vitro. Similar results have also been observed that the overexpression and knockdown of miR-194 strongly disturbed the development and differentiation of the sensory patches and Statoacoustic ganglion (SAG) through Fgf4 in zebrafish in vivo. Our results indicated that miR-194 may regulate the development and differentiation of sensory patches and SAG through Fgf4. CONCLUSIONS Our data revealed a vital role of miR-194 in regulating the development and differentiation of the inner ear. PMID- 29570700 TI - Fluctuating Finite Element Analysis (FFEA): A continuum mechanics software tool for mesoscale simulation of biomolecules. AB - Fluctuating Finite Element Analysis (FFEA) is a software package designed to perform continuum mechanics simulations of proteins and other globular macromolecules. It combines conventional finite element methods with stochastic thermal noise, and is appropriate for simulations of large proteins and protein complexes at the mesoscale (length-scales in the range of 5 nm to 1 MUm), where there is currently a paucity of modelling tools. It requires 3D volumetric information as input, which can be low resolution structural information such as cryo-electron tomography (cryo-ET) maps or much higher resolution atomistic co ordinates from which volumetric information can be extracted. In this article we introduce our open source software package for performing FFEA simulations which we have released under a GPLv3 license. The software package includes a C ++ implementation of FFEA, together with tools to assist the user to set up the system from Electron Microscopy Data Bank (EMDB) or Protein Data Bank (PDB) data files. We also provide a PyMOL plugin to perform basic visualisation and additional Python tools for the analysis of FFEA simulation trajectories. This manuscript provides a basic background to the FFEA method, describing the implementation of the core mechanical model and how intermolecular interactions and the solvent environment are included within this framework. We provide prospective FFEA users with a practical overview of how to set up an FFEA simulation with reference to our publicly available online tutorials and manuals that accompany this first release of the package. PMID- 29570701 TI - Infant outcome at four years of age after intrapartum sampling of scalp blood lactate for fetal assessment. A cohort study. AB - OBJECTIVE: To correlate the value of lactate in fetal scalp blood at delivery and the outcomes of the offspring at four years of age. METHODS: Cases where scalp blood lactate was taken within sixty minutes before delivery were identified from the randomized trial "Determination of pH or lactate in fetal scalp blood in management of intrapartum fetal distress". Data were grouped according to the generally accepted cutoffs for normality, pre-acidemia, acidemia and concentrations above mean +2 SD during the second stage. The outcome measures included gross-/fine motor function, vision, hearing, speaking and cognitive disorders, signs of central motor damage and referral to specialized pediatric services. RESULTS: 307 cases were available for final analyse. With normal scalp lactate concentration, the number of children with a diagnosed disorder was lower compared to the pre-acidemic/acidemic groups, although the findings were only significant for fine motor dysfunction (p = 0.036). Elevated lactate values were significantly associated with increased risk for a poorer capacity of attention and understanding of instructions (OR 1.37, 95% CI 1.07-1.74), and for fine motor dysfunction (OR 1.22, 95% CI 1.00-1.49) at the age of four. CONCLUSION: Higher levels of lactate in fetal scalp blood seems to be associated with increased risk of an aberrant developmental outcome at four years of age in some areas. PMID- 29570702 TI - Sustainable food security in India-Domestic production and macronutrient availability. AB - India has been perceived as a development enigma: Recent rates of economic growth have not been matched by similar rates in health and nutritional improvements. To meet the second Sustainable Development Goal (SDG2) of achieving zero hunger by 2030, India faces a substantial challenge in meeting basic nutritional needs in addition to addressing population, environmental and dietary pressures. Here we have mapped-for the first time-the Indian food system from crop production to household-level availability across three key macronutrients categories of 'calories', 'digestible protein' and 'fat'. To better understand the potential of reduced food chain losses and improved crop yields to close future food deficits, scenario analysis was conducted to 2030 and 2050. Under India's current self sufficiency model, our analysis indicates severe shortfalls in availability of all macronutrients across a large proportion (>60%) of the Indian population. The extent of projected shortfalls continues to grow such that, even in ambitious waste reduction and yield scenarios, enhanced domestic production alone will be inadequate in closing the nutrition supply gap. We suggest that to meet SDG2 India will need to take a combined approach of optimising domestic production and increasing its participation in global trade. PMID- 29570703 TI - Injectable silicone rubber for ocular implantation after evisceration. AB - OBJECTIVE: To investigate the usefulness of addition type liquid silicone rubber (ATLSR) as injectable implant after evisceration to maintain the eyeball volume in an animal experiment. METHODS: Twelve adult New Zealand white rabbits were included. One eye of each rabbit was randomly selected for evisceration with the fellow eye as control. ATLSR was injected to fill the eyeball socket after evisceration. In vivo observation and photographs were performed up to 24 weeks post-op. Two rabbits were sacrificed respectively at post-operative week 1, 2, 4, 8, 12 and 24. After enucleation, the vertical, horizontal and sagittal diameters of the experimental eyeballs were measured and compared with the control eyes. Histopathological studies were performed to evaluate signs of inflammation. RESULTS: Cornea remained clear throughout the observation period despite mild epithelial edema and neovascularization. Compared to the control eyes, the experimental eyes were significantly smaller in vertical diameter (17.00+/-1.17 vs. 17.54+/-1.11 mm, P<0.001), but larger in sagittal diameter (16.85+/-1.48 vs. 16.40+/-1.38 mm, P = 0.008), and had no significant difference in horizontal diameter (17.49+/-1.53 vs. 17.64+/-1.21 mm, P = 0.34). Postoperative inflammation was observed at one week after surgery, which peaked at 2-3 weeks, then regressed gradually. At week 12 and week 24, most of the inflammatory cells disappeared with some residual plasma cells and eosinophils. CONCLUSION: Injectable addition type silicon rubber may be a good choice for ocular implantation after evisceration, maintaining eyeball volume and cosmetically satisfactory when compared to the fellow eye. Spontaneous regression of inflammation implied good biocompatibility for at least 24 weeks. PMID- 29570704 TI - The TIE1 transcriptional repressor controls shoot branching by directly repressing BRANCHED1 in Arabidopsis. AB - Shoot branching is a major determinant of plant architecture and is regulated by both endogenous and environmental factors. BRANCHED1 (BRC1) is a central local regulator that integrates signals controlling shoot branching. So far, the regulation of BRC1 activity at the protein level is still largely unknown. In this study, we demonstrated that TIE1 (TCP interactor containing EAR motif protein 1), a repressor previously identified as an important factor in the control of leaf development, also regulates shoot branching by repressing BRC1 activity. TIE1 is predominantly expressed in young axillary buds. The gain-of function mutant tie1-D produced more branches and the overexpression of TIE1 recapitulated the increased branching of tie1-D, while disruption of TIE1 resulted in lower bud activity and fewer branches. We also demonstrated that the TIE1 protein interacts with BRC1 in vitro and in vivo. Expression of BRC1 fused with the C-terminus of the TIE1 protein in wild type caused excessive branching similar to that observed in tie1-D and brc1 loss-of-function mutants. Transcriptome analyses revealed that TIE1 regulated about 30% of the BRC1 dependent genes, including the BRC1 direct targets HB21, HB40 and HB53. These results indicate that TIE1 acts as a positive regulator of shoot branching by directly repressing BRC1 activity. Thus, our results reveal that TIE1 is an important shoot branching regulator, and provide new insights in the post transcriptional regulation of the TCP transcription factor BRC1.

AB - Early diagnosis is critical for individuals with Alzheimer's disease (AD) in clinical practice because its progress is irreversible. In the existing literature, support vector machine (SVM) has always been applied to distinguish between AD and healthy controls (HC) based on neuroimaging data. But previous studies have only used a single SVM to classify AD and HC, and the accuracy is not very high and generally less than 90%. The method of random support vector machine cluster was proposed to classify AD and HC in this paper. From the Alzheimer's Disease Neuroimaging Initiative database, the subjects including 25 AD individuals and 35 HC individuals were obtained. The classification accuracy could reach to 94.44% in the results. Furthermore, the method could also be used for feature selection and the accuracy could be maintained at the level of 94.44%. In addition, we could also find out abnormal brain regions (inferior frontal gyrus, superior frontal gyrus, precentral gyrus and cingulate cortex). It is worth noting that the proposed random support vector machine cluster could be a new insight to help the diagnosis of AD. PMID- 29570706 TI - Intra-operative biopsy in chronic sinusitis detects pathogenic Escherichia coli that carry fimG/H, fyuA and agn43 genes coding biofilm formation. AB - The aim of this study was to investigate whether or not surgical biopsy of sinus tissue in chronic sinusitis, not responsive to treatment, would detect E. coli. We intended to evaluate E. coli virulence genes, therefore dispute the causal role of such an unusual microorganism in chronic sinusitis, as well as consider effective pathogen-targeted therapy. Patients with E. coli isolated by intra operative puncture biopsy were included in the study. Genetic analysis of E. coli isolates, including phylogenetic grouping and virulence factor characteristics, were done by multiplex PCR. We identified 26 patients with chronic sinusitis, in which 26 E. coli isolates were cultured. The E. coli isolates belonged mainly to pathogenic phylogenetic group B2, and carried multiple virulence genes. Three genes in particular were present in all (100%) of examined isolates, they were (1) marker agn43 gene for forming biofilm, (2) type 1 fimbriae (fimG/H gene) and (3) yersiniabactin receptor (fyuA). Furthermore, a pseudo-phylogenetic tree of virulence genes distribution revealed possible cooperation between agn43, fimG/H, and fyuA in the coding of biofilm formation. Intra-operative-biopsy and culture based therapy, targeting the isolated E. coli, coincided with long-term resolution of symptoms. This is the first report demonstrating an association between a highly pathogenic E. coli, chronic sinus infection, and resolution of symptoms upon E. coli targeted therapy, a significant finding due to the fact that E. coli has not been considered to be a commensal organism of the oropharynx or sinuses. We postulate that the simultaneous presence of three genes, each coding biofilm formation, may in part account for the chronicity of E. coli sinusitis. PMID- 29570708 TI - Dermatological guidelines for monitoring methotrexate treatment reduce drug survival compared to rheumatological guidelines. AB - BACKGROUND: Methotrexate (MTX) is widely used as disease modifying treatment for psoriasis and psoriatic arthritis (PsA). Rheumatological and dermatological guidelines to prevent MTX-induced adverse events diverge in the number and frequency of blood tests. These differences are not based on evidence indicating a higher risk for patients with psoriasis compared to PsA or rheumatic arthritis (RA). This raises the question if multiple testing increases safety, or results in false positive signals potentially leading to early withdrawal of an effective treatment. OBJECTIVE: Compare the effects of MTX monitoring strategies by rheumatologists and dermatologists regarding drug survival, reasons for withdrawal and safety. METHODS: Retrospective follow-up of all patients diagnosed with psoriasis by dermatologists or PsA by rheumatologists. Included were consecutive patients who started methotrexate (MTX) between 2006 and 2012 and had a scheduled follow-up by dermatologist or rheumatologist. Exclusions were: drug not started after the first prescription or incomplete availability of lab data. Data were extracted from electronic records: start and stop dates and dosing of MTX; treatment with folic acid and dose; reasons for withdrawal of MTX; numbers of blood sampling and types of laboratory tests performed for MTX safety; number of abnormal tests; occurrence of any serious adverse event (SAE). RESULTS: 190 Psoriasis and 196 PsA patients starting methotrexate (MTX) were included. Age and sex were comparable. PsA patients used higher initial and maximum doses of MTX and folic acid, but psoriasis patients had a higher frequency of abnormal laboratory results (0.14 vs 0.03 per treatment month, p<0.001), resulting in a striking difference in withdrawal of MTX for abnormal liver enzymes (15.8% vs 3.6%, p<0.001). In PsA patients MTX was withdrawn less frequently for ineffectiveness (15.8 vs 24.2%, p<0.05) leading to longer drug survival in the first course of treatment (37.4+/-30 vs 18.8+/-19.1 months). Repeated courses of MTX were more often prescribed by rheumatologists than by dermatologists. There were no significant differences in the occurrence of SAE (psoriasis 0.0041 vs PsA 0.0038 per treatment month) or death (1.6% vs 2.0%) between these groups. Hospital admissions related to infection were recorded in 6 (3.1%) PsA vs 4 (2.1%) psoriasis patients. CONCLUSION: Strict monitoring by dermatologists resulted in more abnormal findings, which reduced drug survival of MTX. The limited monitoring strategy by rheumatologists was not associated with more SAEs. Further research in other populations is needed to confirm whether reduced intensity of monitoring can optimize the use of MTX with sufficient long-term safety. PMID- 29570707 TI - Long-lived rodents reveal signatures of positive selection in genes associated with lifespan. AB - The genetics of lifespan determination is poorly understood. Most research has been done on short-lived animals and it is unclear if these insights can be transferred to long-lived mammals like humans. Some African mole-rats (Bathyergidae) have life expectancies that are multiple times higher than similar sized and phylogenetically closely related rodents. To gain new insights into genetic mechanisms determining mammalian lifespans, we obtained genomic and transcriptomic data from 17 rodent species and scanned eleven evolutionary branches associated with the evolution of enhanced longevity for positively selected genes (PSGs). Indicating relevance for aging, the set of 250 identified PSGs showed in liver of long-lived naked mole-rats and short-lived rats an expression pattern that fits the antagonistic pleiotropy theory of aging. Moreover, we found the PSGs to be enriched for genes known to be related to aging. Among these enrichments were "cellular respiration" and "metal ion homeostasis", as well as functional terms associated with processes regulated by the mTOR pathway: translation, autophagy and inflammation. Remarkably, among PSGs are RHEB, a regulator of mTOR, and IGF1, both central components of aging relevant pathways, as well as genes yet unknown to be aging-associated but representing convincing functional candidates, e.g. RHEBL1, AMHR2, PSMG1 and AGER. Exemplary protein homology modeling suggests functional consequences for amino acid changes under positive selection. Therefore, we conclude that our results provide a meaningful resource for follow-up studies to mechanistically link identified genes and amino acids under positive selection to aging and lifespan determination. PMID- 29570709 TI - Disentangling factors that shape the gut microbiota in German Shepherd dogs. AB - The aim of this study was to explore the development of the gut microbiota in 168 German Shepherd dogs (30 litters) from 7 weeks to 18 months of age and furthermore, to study the effect of relatedness, maternal microbiota composition and living environment in a large and well-defined population of dogs. Using 454 pyrosequencing, we assessed the effects of pre- and postnatal probiotic supplementation (Lactobacillus johnsonii NCC533 (La1)) and analysed whether administration of the probiotic strain influenced fecal microbiota composition in a placebo controlled double-blinded study. The bitches were treated with probiotics or placebo during last trimester of pregnancy and until their puppies were 8 weeks old, the puppies received the same treatment as their mothers between 3-12 weeks of age. Samples from bitches were collected at pregnancy day 42, partum, 4 weeks postpartum and 7 weeks postpartum and from puppies at the age 4 weeks, 7 weeks, 12-13 months and 15-18 months. Serum IgA, total serum IgE, fecal IgA and IgG antibody responses against canine distemper virus were analysed by ELISA in order to detect any immune stimulating effects of the probiotic strain. Analysis of the fecal microbiota composition showed that the predominant phyla were the same in 7 weeks old puppies as in pregnant and lactating bitches (Firmicutes, Fusobacteria, Bacteroidetes). Proportions among different bacteria as well as diversity varied from 7 weeks old puppies up to 15-18 months of age. Litter mates had a more similar fecal microbiota compared to unrelated dogs and 7 weeks old puppies were more similar to their mothers than to unrelated bitches at 7 weeks postpartum but not at partum. We observed a change in the relative abundance of different bacteria during lactation, and an increase in diversity from pregnancy to end of lactation. The microbial diversity was affected by living area where dogs living in big cities had higher diversity compared to dogs living at the countryside. However, we were not able to demonstrate an effect by pre and postnatal exposure to Lactobacillus johnsonii NCC533 (La1) upon the diversity or composition of the microbiota or the levels of serum IgA, total serum IgE, fecal IgA or vaccine response. Our findings provide a better understanding of the canine fecal microbiota in growing dogs as well as in pregnant and lactating bitches. This information forms a basis for further research on the connection between early gut colonization and immune function later in life. PMID- 29570710 TI - On the nature of real and perceived bias in the mainstream media. AB - News consumers expect news outlets to be objective and balanced in their reports of events and opinions. However, there is a growing body of evidence of bias in the media caused by underlying political and socio-economic viewpoints. Previous studies have tried to classify the partiality of the media, but there is little work on quantifying it, and less still on the nature of this partiality. The vast amount of content published in social media enables us to quantify the inclination of the press to pre-defined sides of the socio-political spectrum. To describe such tendencies, we use tweets to automatically compute a news outlet's political and socio-economic orientation. Results show that the media have a measurable bias, and illustrate this by showing the favoritism of Chilean media for the ruling political parties in the country. This favoritism becomes clearer as we empirically observe a shift in the position of the mass media when there is a change in government. Even though relative differences in bias between news outlets can be observed, public awareness of the bias of the media landscape as a whole appears to be limited by the political space defined by the news that we receive as a population. We found that the nature of the bias is reflected in the vocabulary used and the entities mentioned by different news outlets. A survey conducted among news consumers confirms that media bias has an impact on the coverage of controversial topics and that this is perceivable by the general audience. Having a more accurate method to measure and characterize media bias will help readers position outlets in the socio-economic landscape, even when a (sometimes opposite) self-declared position is stated. This will empower readers to better reflect on the content provided by their news outlets of choice. PMID- 29570711 TI - Smoking intensity and bladder cancer aggressiveness at diagnosis. AB - OBJECTIVE: To explore the relation between cigarette smoking intensity and bladder cancer aggressiveness at first diagnosis. METHODS: Patients diagnosed with urinary bladder cancer (BC) between 1995-2011 under the age of 75 years were retrospectively identified from the Netherlands Cancer Registry and invited for a study on genetic and lifestyle risk factors for BC. Information on patients' self reported smoking history was retrieved by means of a postal questionnaire. Tumors were stratified regarding the risk of progression defined by tumor stage and grade. Multinomial logistic regression was used to analyze the relation between smoking intensity and aggressiveness of the tumor. RESULTS: The UBC study population comprised 323 (17.4%) never smokers, 870 (46.8%) former cigarette smokers, and 630 (33.9%) current cigarette smokers. A higher smoking amount was a risk factor of getting high-risk non-muscle invasive bladder cancer (NMIBC) compared with low-risk NMIBC in ever and former cigarette smokers (OR: 1.02 per cigarette smoked, 95% CI: 1.00-1.03 and OR: 1.03, 95% CI: 1.01-1.05, respectively). A statistically significant dose-response increase in the risk of a more aggressive cancer type (high-risk NMIBC and MIBC) was observed with increasing smoking duration among former smokers (p for trend 0.035 and 0.008, respectively). No significant association of the evaluated smoking intensity variables was observed in current smokers. A longer time of smoking cessation correlated with a lower odds of a more aggressive cancer. CONCLUSION: We observed a weak increase in the risk of a more aggressive tumor type with increasing smoking intensity in former smokers, but this association was absent in current smokers. This conflicting result may suggest that there is no strong relation between smoking intensity and bladder cancer aggressiveness. Analyses of prospective studies with longitudinal smoking assessment may provide a more definitive answer to the research question. PMID- 29570712 TI - Shale gas activity and increased rates of sexually transmitted infections in Ohio, 2000-2016. AB - BACKGROUND: The growing shale gas ("fracking") industry depends on a mobile workforce, whose influx could have social impacts on host communities. Sexually transmitted infections (STIs) can increase through sexual mixing patterns associated with labor migration. No prior studies have quantified the relationship between shale gas activity and rates of three reportable STIs: chlamydia, gonorrhea, and syphilis. METHODS: We conducted a longitudinal, ecologic study from 2000-2016 in Ohio, situated in a prolific shale gas region in the United States (US). Data on reported cases of chlamydia, gonorrhea, and syphilis by county and year were obtained from the Ohio Department of Health. All 88 counties were classified as none, low, and high shale gas activity in each year, using data from the Ohio Department of Natural Resources. Annual rate ratios (RR) and 95% confidence intervals (95% CIs) were calculated from mixed effects Poisson regression models evaluating the relationship between shale gas activity and reported annual STI rates while adjusting for secular trends and potential confounders obtained from the US Census. RESULTS: Compared to counties with no shale gas activity, counties with high activity had 21% (RR = 1.21; 95%CI = 1.08-1.36) increased rates of chlamydia and 19% (RR = 1.27; 95%CI 0.98-1.44) increased rates of gonorrhea, respectively. No association was observed for syphilis. CONCLUSION: This first report of a link between shale gas activity and increased rates of both chlamydia and gonorrhea may inform local policies and community health efforts. PMID- 29570713 TI - Maternal, fetal and perinatal factors associated with necrotizing enterocolitis in Sweden. A national case-control study. AB - OBJECTIVE: To analyze associations of maternal, fetal, gestational, and perinatal factors with necrotizing enterocolitis in a matched case-control study based on routinely collected, nationwide register data. STUDY DESIGN: All infants born in 1987 through 2009 with a diagnosis of necrotizing enterocolitis in any of the Swedish national health care registers were identified. For each case up to 6 controls, matched for birth year and gestational age, were selected. The resulting study population consisted of 720 cases and 3,567 controls. Information on socioeconomic data about the mother, maternal morbidity, pregnancy related diagnoses, perinatal diagnoses of the infant, and procedures in the perinatal period, was obtained for all cases and controls and analyzed with univariable and multivariable logistic regressions for the whole study population as well as for subgroups according to gestational age. RESULTS: In the study population as a whole, we found independent positive associations with necrotizing enterocolitis for isoimmunization, fetal distress, cesarean section, neonatal bacterial infection including sepsis, erythrocyte transfusion, persistent ductus arteriosus, cardiac malformation, gastrointestinal malformation, and chromosomal abnormality. Negative associations were found for maternal weight, preeclampsia, maternal urinary infection, premature rupture of the membranes, and birthweight. Different patterns of associations were seen in the subgroups of different gestational age. CONCLUSION: With some interesting exceptions, especially in negative associations, the results of this large, population based study, are in keeping with earlier studies. Although restrained by the limitations of register data, the findings mirror conceivable pathophysiological processes and underline that NEC is a multifactorial disease. PMID- 29570714 TI - Nascent RNA signaling to yeast RNA Pol II during transcription elongation. AB - Transcription as the key step in gene expression is a highly regulated process. The speed of transcription elongation depends on the underlying gene sequence and varies on a gene by gene basis. The reason for this sequence dependence is not known in detail. Recently, our group studied the cross talk between the nascent RNA and the transcribing RNA polymerase by screening the Escherichia coli genome for RNA sequences with high affinity to RNA Pol by performing genomic SELEX. This approach led to the identification of RNA polymerase-binding APtamers termed "RAPs". RAPs can have positive and negative effects on gene expression. A subgroup is able to downregulate transcription via the activity of the termination factor Rho. In this study, we used a similar SELEX setup using yeast genomic DNA as source of RNA sequences and highly purified yeast RNA Pol II as bait and obtained almost 1300 yeast-derived RAPs. Yeast RAPs are found throughout the genome within genes and antisense to genes, they are overrepresented in the non-transcribed strand of yeast telomeres and underrepresented in intergenic regions. Genes harbouring a RAP are more likely to show lower mRNA levels. By determining the endogenous expression levels as well as using a reporter system, we show that RAPs located within coding regions can reduce the transcript level downstream of the RAP. Here we demonstrate that RAPs represent a novel type of regulatory RNA signal in Saccharomyces cerevisiae that act in cis and interfere with the elongating transcription machinery to reduce the transcriptional output. PMID- 29570715 TI - Preoperative statins are associated with a reduced risk of postoperative delirium following vascular surgery. AB - Delirium is a common complication of vascular surgery. The protective effect of preoperative statins on delirium after vascular surgery is controversial. The authors hypothesized that preoperative statin administration would decrease the incidence of delirium after vascular surgery. From May 2010 to May 2015, 1,132 patients underwent vascular surgery. Postoperative delirium was diagnosed from patients' medical records. The incidence of delirium was 11.5%. The preoperative statin exposure was not associated with reduced delirium in the univariate analysis. After adjusting for covariates, preoperative statin exposure was associated with reduced delirium (OR, 0.54; 95% CI, 0.33-0.87; p = 0.011). This favor effect of statin for delirium was observed after propensity matching (OR, 0.59; 95% CI, 0.34-1.02; p = 0.060). However, the median hospital lengths of stay and in-hospital mortality were not statistically different between the two groups. CRP(C-reactive protein) levels in the unmatched population were lower in the preoperative statin group compared with the other group (p<0.001), however, there was only numerically different without statistical difference after matching (p = 0.083). Preoperative statin use was associated with a decreased incidence of postoperative delirium in patients who underwent vascular surgery. However, preoperative statin did not reduce mortality rate and hospital stay. PMID- 29570716 TI - The long-range interaction map of ribosomal DNA arrays. AB - The repeated rDNA array gives rise to the nucleolus, an organelle that is central to cellular processes as varied as stress response, cell cycle regulation, RNA modification, cell metabolism, and genome stability. The rDNA array is also responsible for the production of more than 70% of all cellular RNAs (the ribosomal RNAs). The rRNAs are produced from two sets of loci: the 5S rDNA array resides exclusively on human chromosome 1 while the 45S rDNA arrays reside on the short arm of five human acrocentric chromosomes. These critical genome elements have remained unassembled and have been excluded from all Hi-C analyses to date. Here we built the first high resolution map of 5S and 45S rDNA array contacts with the rest of the genome combining over 15 billion Hi-C reads from several experiments. The data enabled sufficiently high coverage to map rDNA-genome interactions with 1MB resolution and identify rDNA-gene contacts. The map showed that the 5S and 45S arrays display preferential contact at common sites along the genome but are not themselves sufficiently close to yield 5S-45S Hi-C contacts. Ribosomal DNA contacts are enriched in segments of closed, repressed, and late replicating chromatin, as well as CTCF binding sites. Finally, we identified functional categories whose dispersed genes coalesced in proximity to the rDNA arrays or instead avoided proximity with the rDNA arrays. The observations further our understanding of the spatial localization of rDNA arrays and their contribution to the architecture of the cell nucleus. PMID- 29570717 TI - Population dynamics of engineered underdominance and killer-rescue gene drives in the control of disease vectors. AB - A number of different genetics-based vector control methods have been proposed. Two approaches currently under development in Aedes aegypti mosquitoes are the two-locus engineered underdominance and killer-rescue gene drive systems. Each of these is theoretically capable of increasing in frequency within a population, thus spreading associated desirable genetic traits. Thus they have gained attention for their potential to aid in the fight against various mosquito vectored diseases. In the case of engineered underdominance, introduced transgenes are theoretically capable of persisting indefinitely (i.e. it is self sustaining) whilst in the killer-rescue system the rescue component should initially increase in frequency (while the lethal component (killer) is common) before eventually declining (when the killer is rare) and being eliminated (i.e. it is temporally self-limiting). The population genetics of both systems have been explored using discrete generation mathematical models. The effects of various ecological factors on these two systems have also been considered using alternative modelling methodologies. Here we formulate and analyse new mathematical models combining the population dynamics and population genetics of these two classes of gene drive that incorporate ecological factors not previously studied and are simple enough to allow the effects of each to be disentangled. In particular, we focus on the potential effects that may be obtained as a result of differing ecological factors such as strengths of larval competition; numbers of breeding sites; and the relative fitness of transgenic mosquitoes compared with their wild-type counterparts. We also extend our models to consider population dynamics in two demes in order to explore the effects of dispersal between neighbouring populations on the outcome of UD and KR gene drive systems. PMID- 29570718 TI - Taxonomic revision of Chloromonas nivalis (Volvocales, Chlorophyceae) strains, with the new description of two snow-inhabiting Chloromonas species. AB - Chloromonas nivalis (Volvocales, Chlorophyceae) is considered a cosmopolitan species of a snow-inhabiting microalga because cysts morphologically identifiable as zygotes of the species are distributed worldwide. However, recent molecular data demonstrated that field-collected cysts identified as the zygotes consist of multiple species. Recently, we demonstrated that species identification of snow inhabiting Chloromonas species is possible based on light and electron microscopy of asexual life cycles in strains and molecular phylogenetic analyses. Vegetative cells without eyespots and of inverted-teardrop shape have been reported once in North American material of C. nivalis; however, strains with such vegetative cells in snow-inhabiting species of Chloromonas have not been examined taxonomically in detail. Here, we used light and transmission electron microscopy together with molecular analyses of multiple DNA sequences to examine several C. nivalis strains. The morphological data demonstrated that one North American strain could be identified as C. nivalis, whereas three other strains should be re-classified as C. hoshawii sp. nov. and C. remiasii sp. nov. based on vegetative cell morphology, the number of zoospores within the parental cell wall during asexual reproduction, and whether cell aggregates (resulting from repeated divisions of daughter cells retained within a parental cell wall) were observed in the culture. This taxonomic treatment was supported by multigene phylogeny and comparative molecular analyses that included a rapidly evolving DNA region. Our molecular phylogenetic analyses also demonstrated that the North American strain of C. nivalis was phylogenetically separated from the Austrian and Japanese specimens previously identified as C. nivalis based on zygote morphology. PMID- 29570720 TI - The double burden of disease and the challenge of health access: Evidence from Access, Bottlenecks, Cost and Equity facility survey in Ghana. AB - Despite the double burden of infectious and chronic non-communicable diseases in Africa, health care expenditure disproportionately favours infectious diseases. In this paper, we examine quantitatively the extent of this disproportionate access to diagnoses and treatment of diabetes, hypertension and malaria in Ghana. A total of 220 health facilities was surveyed across the country in 2011. Findings indicate that diagnoses and treatment of infectious diseases were more accessible than NCDs. In terms of treatment, 78% and 87% of health facilities had two of the recommended malaria drugs while less than 35% had essential diabetes and hypertension drugs. There is a significant unmet need for diagnoses and treatment of NCDs in Ghana. These inequities have implications for high morbidity and mortality from NCDs. We recommend the use of task shifting as a model to increase the delivery of NCD services. PMID- 29570719 TI - Avian viral surveillance in Victoria, Australia, and detection of two novel avian herpesviruses. AB - Viruses in avian hosts can pose threats to avian health and some have zoonotic potential. Hospitals that provide veterinary care for avian patients may serve as a site of exposure of other birds and human staff in the facility to these viruses. They can also provide a useful location to collect samples from avian patients in order to examine the viruses present in wild birds. This study aimed to investigate viruses of biosecurity and/or zoonotic significance in Australian birds by screening samples collected from 409 birds presented to the Australian Wildlife Health Centre at Zoos Victoria's Healesville Sanctuary for veterinary care between December 2014 and December 2015. Samples were tested for avian influenza viruses, herpesviruses, paramyxoviruses and coronaviruses, using genus- or family-wide polymerase chain reaction methods coupled with sequencing and phylogenetic analyses for detection and identification of both known and novel viruses. A very low prevalence of viruses was detected. Columbid alphaherpesvirus 1 was detected from a powerful owl (Ninox strenua) with inclusion body hepatitis, and an avian paramyxovirus most similar to Avian avulavirus 5 was detected from a musk lorikeet (Glossopsitta concinna). Two distinct novel avian alphaherpesviruses were detected in samples from a sulphur-crested cockatoo (Cacatua galerita) and a tawny frogmouth (Podargus strigoides). Avian influenza viruses and avian coronaviruses were not detected. The clinical significance of the newly detected viruses remains undetermined. Further studies are needed to assess the host specificity, epidemiology, pathogenicity and host-pathogen relationships of these novel viruses. Further genome characterization is also indicated, and would be required before these viruses can be formally classified taxonomically. The detection of these viruses contributes to our knowledge on avian virodiversity. The low level of avian virus detection, and the absence of any viruses with zoonotic potential, suggests low risk to biosecurity and human health. PMID- 29570721 TI - Structural and functional analyses of the optic nerve and lateral geniculate nucleus in glaucoma. AB - PURPOSE: To analyze the correlation between structural characteristics of intraorbital optic nerve (ION) and lateral geniculate nucleus (LGN) measured by 3 Tesla magnetic resonance imaging (3T MRI), and the severity of glaucomatous damage. METHODS: In this cross-sectional study, 41 glaucoma patients and 12 age- and sex-matched controls underwent standard automated perimetry (SAP) and frequency doubling technology (FDT) as functional evaluation; optic disc stereophotograph, spectral-domain optical coherence tomography (OCT) and confocal scanning laser tomography as ocular structural evaluation; and 3T MRI. Structure structure and structure-function correlation were performed using bootstrap resampling method for clustered data. RESULTS: The ION mean diameter and cross sectional area were different between glaucoma and control groups at 5mm and 10mm (all, p<=0.011) from the globe, but not at 15mm (both, p>=0.067). LGN height was significantly lower in glaucoma group (p = 0.005). OCT rim area and functional parameters (SAP and FDT) correlated significantly with all ION segments, showing stronger correlations at 10 and 15 mm. ION parameters at 10 and 15 mm presented mild-to-moderate correlation with OCT peripapillary nerve fiber layer thickness, and ION at 15mm had mild association with the neuroretinal rim area on stereophotographs. Although LGN height was significantly smaller in glaucoma group (p = 0.005), LGN parameters were not associated with any ocular structural or functional parameter. CONCLUSION: Assessment of central and peripheral nervous systems using 3T MRI confirmed that glaucoma patients had smaller ION dimensions and LGN height compared to the control group. In general, ION dimensions presented mild to moderate correlations with functional and ocular structural parameters. Although ION had significant correlations at any distance from the eye, the ION distal locations correlated better with OCT results and functional parameters. However, LGN parameters were not associated with functional or ocular structural parameters. PMID- 29570722 TI - Thoracic dysfunction in whiplash associated disorders: A systematic review. AB - BACKGROUND: Research investigating Whiplash Associated Disorder (WAD) has largely focused on the cervical spine yet symptoms can be widespread. Thoracic spine pain prevalence is reported ~66%; perhaps unsurprising given the forceful stretch/eccentric loading of posterior structures of the spine, and the thoracic spine's contribution to neck mobility/function. Approximately 50% WAD patients develop chronic pain and disability resulting in high levels of societal and healthcare costs. It is time to look beyond the cervical spine to fully understand anatomical dysfunction in WAD and provide new directions for clinical practice and research. PURPOSE: To evaluate the scope and nature of dysfunction in the thoracic region in patients with WAD. METHODS: A systematic review and data synthesis was conducted according to a pre-defined, registered (PROSPERO, CRD42015026983) and published protocol. All forms of observational study were included. A sensitive topic-based search strategy was designed from inception to 1/06/16. Databases, grey literature and registers were searched using a study population terms and key words derived from scoping search. Two reviewers independently searched information sources, assessed studies for inclusion, extracted data and assessed risk of bias. A third reviewer checked for consistency and clarity. Extracted data included summary data: sample size and characteristics, outcomes, and timescales to reflect disorder state. Risk of bias was assessed using the Newcastle-Ottawa Scale. Data were tabulated to allow enabling a semi-qualitative comparison and grouped by outcome across studies. Strength of the overall body of evidence was assessed using a modified GRADE. RESULTS: Thirty eight studies (n>50,000) which were conducted across a range of countries were included. Few authors responded to requests for further data (5 of 9 contacted). Results were reported in the context of overall quality and were presented for measures of pain or dysfunction and presented, where possible, according to WAD severity and time point post injury. Key findings include: 1) high prevalence of thoracic pain (>60%); higher for those with more severe presentations and in the acute stage, 2) low prevalence of chest pain (<22%), 3) evidence of thoracic outlet syndrome, with some association to and involvement of the brachial plexus, 4) muscle dysfunction in the form of heightened activity of the sternocleidomastoid or delayed onset of action of the serratus anterior, 5) high prevalence of myofascial pain and trigger points in the scalene muscles, sternocleidomastoid and mid/lower fibres of trapezius muscle (48-65%), and 6) inconclusive evidence of altered thoracic posture or mobility. CONCLUSIONS: Considerable evidence supports thoracic pain and dysfunction in patients with WAD, involving primarily nerves and muscles. Notwithstanding the low/very low level of evidence from this review, our findings do support a more extensive clinical evaluation of patients presenting with WAD. Additional high quality research is required to further characterise dysfunction across other structures in the thoracic region, including but not limited to the thoracic spine (mobility and posture) and thoracic muscles (stiffness, activation patterns). In turn this may inform the design of clinical trials targeting such dysfunction. PMID- 29570723 TI - HIV treatment eligibility expansion and timely antiretroviral treatment initiation following enrollment in HIV care: A metaregression analysis of programmatic data from 22 countries. AB - BACKGROUND: The effect of antiretroviral treatment (ART) eligibility expansions on patient outcomes, including rates of timely ART initiation among those enrolling in care, has not been assessed on a large scale. In addition, it is not known whether ART eligibility expansions may lead to "crowding out" of sicker patients. METHODS AND FINDINGS: We examined changes in timely ART initiation (within 6 months) at the original site of HIV care enrollment after ART eligibility expansions among 284,740 adult ART-naive patients at 171 International Epidemiology Databases to Evaluate AIDS (IeDEA) network sites in 22 countries where national policies expanding ART eligibility were introduced between 2007 and 2015. Half of the sites included in this analysis were from Southern Africa, one-third were from East Africa, and the remainder were from the Asia-Pacific, Central Africa, North America, and South and Central America regions. The median age of patients enrolling in care at contributing sites was 33.5 years, and the median percentage of female patients at these clinics was 62.5%. We assessed the 6-month cumulative incidence of timely ART initiation (CI ART) before and after major expansions of ART eligibility (i.e., expansion to treat persons with CD4 <= 350 cells/MUL [145 sites in 22 countries] and CD4 <= 500 cells/MUL [152 sites in 15 countries]). Random effects metaregression models were used to estimate absolute changes in CI-ART at each site before and after guideline expansion. The crude pooled estimate of change in CI-ART was 4.3 percentage points (95% confidence interval [CI] 2.6 to 6.1) after ART eligibility expansion to CD4 <= 350, from a baseline median CI-ART of 53%; and 15.9 percentage points (pp) (95% CI 14.3 to 17.4) after ART eligibility expansion to CD4 <= 500, from a baseline median CI-ART of 57%. The largest increases in CI-ART were observed among those newly eligible for treatment (18.2 pp after expansion to CD4 <= 350 and 47.4 pp after expansion to CD4 <= 500), with no change or small increases among those eligible under prior guidelines (CD4 <= 350: -0.6 pp, 95% CI -2.0 to 0.7 pp; CD4 <= 500: 4.9 pp, 95% CI 3.3 to 6.5 pp). For ART eligibility expansion to CD4 <= 500, changes in CI-ART were largest among younger patients (16-24 years: 21.5 pp, 95% CI 18.9 to 24.2 pp). Key limitations include the lack of a counterfactual and difficulty accounting for secular outcome trends, due to universal exposure to guideline changes in each country. CONCLUSIONS: These findings underscore the potential of ART eligibility expansion to improve the timeliness of ART initiation globally, particularly for young adults.

AB - Lifestyle interventions in type 2 diabetes (DM2) prevention implementation studies can be effective and lasting. Long-term weight loss maintenance enhances the intervention effect through a significant decrease in diabetes incidence over time. Our objective was to identify factors predicting long-term successful weight reduction maintenance achieved during a DM2 prevention program in patients with high DM2 risk in primary health care. Study participants (n = 263), middle aged, slightly obese with baseline increased DM2 risk (Finnish Diabetes Risk Score (FINDRISC)>14), but no diabetes were invited to receive 11 lifestyle counselling sessions, guided physical activity sessions and motivational support during 10-months. The study participants had three clinical examinations during the study (baseline, one and three years). Stepwise regression analysis was used to determine demographic, clinical, and lifestyle predictors of weight reduction maintenance two years after the discontinuation of the intervention. Out of 105 patients who completed all three examinations (baseline age 56.6 (standard deviation (SD) = 10.7), body mass index 31.1 kg/m2 (SD = 4.9), FINDRISC 18.6 (SD = 3.1)), 73 patients (70%) showed weight loss during the intervention (mean weight loss 4.2 kg, SD = 5.1). The total weight loss achieved in the maintainers (27 of 73 study participants) two years after the intervention had finished was 6.54 kg (4.47 kg+2.0 kg). The non-maintainers, on the other hand, returned to their initial weight at the start of the intervention (+0.21 kg). In multivariable analysis baseline history of increased glucose (odds ratio (OR) = 3.7; 95% confidence interval (CI) 1.0-13.6) and reduction of total fat in diet during follow-up (OR = 4.3; 95% CI 1.5-12.2) were independent predictors of successful weight loss. Further studies exploring predictors of weight loss maintenance in diabetes prevention are needed to help health care providers to redesign interventions and improve long-term outcomes of real life interventions.

AB - In a Guest Editorial, Madhukar Pai discusses the need for high-burden burden, middle-income countries to take a leading role in tuberculosis research. PMID- 29570727 TI - miR-126-5p by direct targeting of JNK-interacting protein-2 (JIP-2) plays a key role in Theileria-infected macrophage virulence. AB - Theileria annulata is an apicomplexan parasite that infects and transforms bovine macrophages that disseminate throughout the animal causing a leukaemia-like disease called tropical theileriosis. Using deep RNAseq of T. annulata-infected B cells and macrophages we identify a set of microRNAs induced by infection, whose expression diminishes upon loss of the hyper-disseminating phenotype of virulent transformed macrophages. We describe how infection-induced upregulation of miR 126-5p ablates JIP-2 expression to release cytosolic JNK to translocate to the nucleus and trans-activate AP-1-driven transcription of mmp9 to promote tumour dissemination. In non-disseminating attenuated macrophages miR-126-5p levels drop, JIP-2 levels increase, JNK1 is retained in the cytosol leading to decreased c-Jun phosphorylation and dampened AP-1-driven mmp9 transcription. We show that variation in miR-126-5p levels depends on the tyrosine phosphorylation status of AGO2 that is regulated by Grb2-recruitment of PTP1B. In attenuated macrophages Grb2 levels drop resulting in less PTP1B recruitment, greater AGO2 phosphorylation, less miR-126-5p associated with AGO2 and a consequent rise in JIP-2 levels. Changes in miR-126-5p levels therefore, underpin both the virulent hyper-dissemination and the attenuated dissemination of T. annulata-infected macrophages. PMID- 29570728 TI - At-hatch administration of probiotic to chickens can introduce beneficial changes in gut microbiota. AB - Recent advances in culture-free microbiological techniques bring new understanding of the role of intestinal microbiota in heath and performance. Intestinal microbial communities in chickens assume a near-stable state within the week which leaves a very small window for permanent microbiota remodelling. It is the first colonisers that determine the fate of microbial community in humans and birds alike, and after the microbiota has matured there are very small odds for permanent modification as stable community resists change. In this study we inoculated broiler chicks immediately post hatch, with 3 species of Lactobacillus, identified by sequencing of 16S rRNA and pheS genes as L. ingluviei, L. agilis and L. reuteri. The strains were isolated from the gut of healthy chickens as reproducibly persistent Lactobacillus strains among multiple flocks. Birds inoculated with the probiotic mix reached significantly higher weight by 28 days of age. Although each strain was able to colonise when administered alone, administering the probiotic mix at-hatch resulted in colonisation by only L. ingluviei. High initial abundance of L. ingluviei was slowly reducing, however, the effects of at-hatch administration of the Lactobacillus mix on modifying microbiota development and structure remained persistent. There was a tendency of promotion of beneficial and reduction in pathogenic taxa in the probiotic administered group. PMID- 29570729 TI - Expand your body when you look at yourself: The role of the posture in a mirror exposure task. AB - Mirror exposure (ME) is one of the main components of the treatment of patients with eating disorders symptomatology and it has shown its effectiveness in improving several outcomes (e.g., body dissatisfaction). However, the study as to what body posture should be adopted to maximize its effectiveness has been neglected. From embodied cognition and emotion theories, the adoption of an expansive (vs. contractive) body posture has been associated with positive changes in cognitive and emotional responses. The objective of this study was to analyze the effect of adopting an expansive (vs. contractive) posture before an ME task on body-related emotions and cognitions, as well as to analyze the possible moderator and mediator variables of these relationships. The sample was composed of 68 women (age: M = 21.74, SD = 3.12) with high scores on body dissatisfaction. Participants were randomly assigned to the expansive or contractive condition, where the openness of the arms/legs and the back position were manipulated. Posture was monitored by an electronic device and participants filled out several self-reported measures. ANCOVAs, moderation, mediation, and moderated mediated analyses were performed. Results showed that women in the expansive condition showed higher positive emotions after the ME. Moreover, exploratory analyses showed that adopting an expansive posture improved positive emotions, leading to improvements in negative emotions, body image satisfaction, and appraisal of the person's own body. Psychological interventions should explore the value of holding an expansive posture before the ME in women with body dissatisfaction.

AB - BACKGROUND: The need to evaluate the human health safety of fishery resources remain urgent in the mist of the ever-increasing fear of heavy metal toxicity from the consumption of Ghana's fisheries resource, as a consequence of pollution from several anthropogenic activities including artisanal gold mining. Nevertheless, the bigeye grunt (Brachydeuterus auritus) and Bagrid catfish (Chrysichthys nigrodigitatus) remain commercially valuable fish species in West Africa and continue to attract high patronage. METHOD: Forty-five specimens each of C. nigrodigitatus and B. auritus collected from the Weija Dam and the Tema Fishing Habour in Ghana, between June and September 2016, were analysed for seven heavy metals using Atomic Absorption Spectrometry. RESULT: Lead and Cadmium were below detection in all samples while Cu was not detected in B. auritus. Levels of the remaining metals (mg kg-1) were below FAO/WHO maximum permissible limits in fish and occurred in the rank order Se (3.5) > Zn (2.34) > Cu (0.59) > As (0.37) > Hg (0.19) in C. nigrodigitatus and Se (2.97) > Zn (2.28) > Hg (0.31) > As (0.21) in B. auritus. Only As in C. nigrodigitatus recorded Estimated Weekly Intake (EWI) greater than FAO/WHO Provisional Tolerable Weekly Intake (PTWI). Also, As in C. nigrodigitatus and Hg in B. auritus had Targeted Hazard Quotient (THQ) greater than 1 for individuals consuming the fishes on daily basis and therefore, raising concerns. However, for both species of fish, cancer risk of As was 1 in 10,000,000,000 and modified Health Benefits values of Se (HBVSe) were positive indicating the health risks that might accompany Hg exposure would be negated. Since toxicity depends on the concentration and quantity of a pollutant consumed, safe maximum consumption rate of C. nigrodigitatus based on As concentrations was 0.21 mg per day and that of B. auritus was 0.058 mg per day for Hg. With an average of 0.227 kg fish per meal of an adult human, these translated into not more than 24 C. nigrodigitatus and nine (9) B. auritus meals in a month but because fish is consumed at 0.0685 kg per person per day in Ghana, these values respectively translates to 93 and 30 safe days of consumption per month. CONCLUSION: At the rate of 0.0685 kg fish per person per day that fish is consumed in Ghana, the consumption of the two species of fish in Ghana would essentially be of little or no consequence to consumers.

AB - Low bone mineral density (BMD) is a risk factor of osteoporotic fracture (OF). Peripheral blood monocytes (PBM) can differentiate into osteoclasts to resorb bone. It was known that PBM-expressed Anxa2 protein is associated with BMD, and extracellular Anxa2 protein promotes osteoclastogenesis. This study aimed to test 1) whether Anxa2 protein level in PBM differs significantly between subjects with OF and without fracture history (NF); 2) whether Anxa2 level in plasma is associated with BMD; 3) how Anxa2 protein at various concentrations would affect osteoblastic activity in vitro. All the study subjects were Chinese Han elderly. Firstly, Anxa2 protein in PBM was identified and quantitated by LC-MS/MS and compared between 45 OF cases and 42 healthy controls. Secondly, plasma Anxa2 protein level was quantitated by ELISA and compared between unrelated subjects with extremely low vs. high hip BMD (0.63+/-0.10 vs. 1.05+/-0.10 g/cm2, n = 75). Furthermore, in vitro functional assay was utilized to test the effects of extracellular Anxa2 protein on osteoblastic growth. We found that Anxa2 protein expression in PBM was significantly up-regulated in OF vs. NF subjects (fold change [FC)] = 1.16, P<0.05). Plasma Anxa2 protein concentration (range: 31.69 227.35ng/ml) was significantly elevated in low vs. high BMD subjects (84.85 vs. 66.15ng/ml, FC = 1.28, P<0.05). Cellular dynamical monitoring demonstrated that the general shape of dose-response relationship is the inverse U-shaped curve. Specifically, lower dose of Anxa2 protein may promote osteoblast growth and the optimal concentration for osteoblastic growth was around 50ng/ml, but even higher concentration could attenuate hFOB1.19 osteoprogenitor cell growth. We concluded that Anxa2 protein could attenuate osteoblast growth and be associated with hip BMD and OF in Chinese elderly. PMID- 29570732 TI - Discovery of ancient Roman "highway" reveals geomorphic changes in karst environments during historic times. AB - Sinkholes are a well-known geologic hazard but their past occurrence, useful for subsidence risk prediction, is difficult to define, especially for ancient historic times. Consequently, our knowledge about Holocene carbonate landscapes is often limited. A multidisciplinary study of Trieste Karst (Italy), close to early Roman military fortifications, led to the identification of possible ancient road tracks, cut by at least one sinkhole. Electrical Resistivity Tomography through the sinkhole has suggested the presence of a cave below its bottom, possibly responsible of the sinkhole formation, while Ground Penetrating Radar has detected no tectonic disturbances underneath the tracks. Additionally, archaeological surveys led to the discovery of over 200 Roman shoe hobnails within or close to the investigated route. According to these data, the tracks are interpreted as the remains of a main Roman road, whose itinerary has been reconstructed for more than 4 km together with other elements of ancient landscape. Our results provide the first known evidence of a Roman main road swallowed by sinkholes and suggest that Holocene karst landscapes could be much different from what previously believed. In fact, sinkholes visible nowadays in the investigated region could have been flat areas filled by sediments up to the Roman time. PMID- 29570733 TI - Ribosome profiling reveals changes in translational status of soybean transcripts during immature cotyledon development. AB - To understand translational capacity on a genome-wide scale across three developmental stages of immature soybean seed cotyledons, ribosome profiling was performed in combination with RNA sequencing and cluster analysis. Transcripts representing 216 unique genes demonstrated a higher level of translational activity in at least one stage by exhibiting higher translational efficiencies (TEs) in which there were relatively more ribosome footprint sequence reads mapping to the transcript than were present in the control total RNA sample. The majority of these transcripts were more translationally active at the early stage of seed development and included 12 unique serine or cysteine proteases and 16 2S albumin and low molecular weight cysteine-rich proteins that may serve as substrates for turnover and mobilization early in seed development. It would appear that the serine proteases and 2S albumins play a vital role in the early stages. In contrast, our investigation of profiles of 19 genes encoding high abundance seed storage proteins, such as glycinins, beta-conglycinins, lectin, and Kunitz trypsin inhibitors, showed that they all had similar patterns in which the TE values started at low levels and increased approximately 2 to 6-fold during development. The highest levels of these seed protein transcripts were found at the mid-developmental stage, whereas the highest ribosome footprint levels of only up to 1.6 TE were found at the late developmental stage. These experimental findings suggest that the major seed storage protein coding genes are primarily regulated at the transcriptional level during normal soybean cotyledon development. Finally, our analyses also identified a total of 370 unique gene models that showed very low TE values including over 48 genes encoding ribosomal family proteins and 95 gene models that are related to energy and photosynthetic functions, many of which have homology to the chloroplast genome. Additionally, we showed that genes of the chloroplast were relatively translationally inactive during seed development. PMID- 29570734 TI - Characterization of the adult Aedes aegypti early midgut peritrophic matrix proteome using LC-MS. AB - The Aedes aegypti mosquito is the principal vector of arboviruses such as dengue, chikungunya, yellow fever, and Zika virus. These arboviruses are transmitted during adult female mosquito bloodfeeding. While these viruses must transverse the midgut to replicate, the blood meal must also reach the midgut to be digested, absorbed, or excreted, as aggregation of blood meal metabolites can be toxic to the female mosquito midgut. The midgut peritrophic matrix (PM), a semipermeable extracellular layer comprised of chitin fibrils, glycoproteins, and proteoglycans, is one such mechanism of protection for the mosquito midgut. However, this structure has not been characterized for adult female Ae. aegypti. We conducted a mass spectrometry based proteomic analysis to identify proteins that comprise or are associated with the adult female Ae. aegypti early midgut PM. Altogether, 474 unique proteins were identified, with 115 predicted as secreted. GO-term enrichment analysis revealed an abundance of serine-type proteases and several known and novel intestinal mucins. In addition, approximately 10% of the peptides identified corresponded to known salivary proteins, indicating Ae. aegypti mosquitoes extensively swallow their own salivary secretions. However, the physiological relevance of this remains unclear, and further studies are needed to determine PM proteins integral for midgut protection from blood meal derived toxicity and pathogen protection. Finally, we describe substantial discordance between previously described transcriptionally changes observed in the midgut in response to a bloodmeal and the presence of the corresponding protein in the PM. Data are available via ProteomeXchange with identifier PXD007627. PMID- 29570736 TI - Medical expenditure and unmet need of the pre-elderly and the elderly according to job status in Korea: Are the elderly indeed most vulnerable? AB - Increase in the elderly population and early retirement imposes immense economic burden on societies. Previous studies on the association between medical expenditure and working status in the elderly population have not adequately addressed reverse causality problem. In addition, the pre-elderly group has hardly been discussed in this regard. This study assessed possible causal association between employment status and medical expenditure as well as employment status and medical unmet needs in a representative sample of the Korean elderly (aged?65) and the pre-elderly (aged ?50 and < 65) adults from the Korea Health Panel Data (KHP). Dynamic panel Generalized Method of Moments (GMM) estimation was employed for the analysis of medical expenditure to address reverse causality, and fixed effect panel logistic regression was used for the analysis of unmet need. The results showed no significant association between job status and medical expenditure in the elderly, but a negative and significant influence on the level of medical expenditure in the pre-elderly. Unemployment was a significant determinant of lowering unmet need from lack of time while it was not associated with unmet need from financial burden in the fixed-effect panel model for both the elderly and pre-elderly groups. The pre-elderly adults were more likely to reduce necessary health service utilization due to unemployment compared to the elderly group because there is no proper financial safety net for the pre-elderly, which may cause non-adherence to treatment and therefore lead to negative health effects. The policy dialogue on safety net currently centers only on the elderly, but should be extended to the pre-elderly population. PMID- 29570735 TI - Microbial diversity in two traditional bacterial douchi from Gansu province in northwest China using Illumina sequencing. AB - Douchi has been consumed as a flavoring ingredient for centuries. During production of douchi, numerous microorganisms play important roles in the hydrolysis and conversion of proteins and starch, which are related to the quality and flavor of the end product. Therefore, in the present study, the microbial diversity in two types of home-made traditional bacterial douchi from Gansu province in northwest China was studied by high-throughput sequencing, and a corresponding analysis of the bacterial and fungal communities were conducted. The results showed that geography may have impacted the fungal diversity and the bacterial and fungal species richness in the samples. The results also showed that the microbial community was significantly different in samples of different origin and the difference in the microbial community at the genus level was greater than at phylum level. Two dominant bacterial genera (Bacillus and Ignatzschineria) were common to the two samples, both of which had a relative abundance of more than 1%. Four bacterial genera (Staphylococcus, Aerococcus, Geobacillus, and Jeotgalicoccus) were dominant only in the sample from Qingyang, while another four (Carnobacterium, Proteus, Aneurinibacillus, and Enterococcus) were dominant only in the sample from Longnan. Two dominant fungal genera (Pichia and Candida) were shared by the two samples. Additionally, two genera (Rhodosporidium and Yarrowia) were dominant only in samples from Longnan. The functional genes of the bacteria present in samples indicated that a significant difference was observed in the bacterial community between samples of different origin. We also found that microbial interactions between bacterial and fungal communities in the samples were very complex. This study provides previously unknown information regarding the impact of the environment on microbial communities in douchi and lays a foundation for further investigations into food ecology in bacterial douchi. PMID- 29570737 TI - Implementing parallel spreadsheet models for health policy decisions: The impact of unintentional errors on model projections. AB - BACKGROUND: Spreadsheet software is increasingly used to implement systems science models informing health policy decisions, both in academia and in practice where technical capacity may be limited. However, spreadsheet models are prone to unintentional errors that may not always be identified using standard error-checking techniques. Our objective was to illustrate, through a methodologic case study analysis, the impact of unintentional errors on model projections by implementing parallel model versions. METHODS: We leveraged a real world need to revise an existing spreadsheet model designed to inform HIV policy. We developed three parallel versions of a previously validated spreadsheet-based model; versions differed by the spreadsheet cell-referencing approach (named single cells; column/row references; named matrices). For each version, we implemented three model revisions (re-entry into care; guideline-concordant treatment initiation; immediate treatment initiation). After standard error checking, we identified unintentional errors by comparing model output across the three versions. Concordant model output across all versions was considered error free. We calculated the impact of unintentional errors as the percentage difference in model projections between model versions with and without unintentional errors, using +/-5% difference to define a material error. RESULTS: We identified 58 original and 4,331 propagated unintentional errors across all model versions and revisions. Over 40% (24/58) of original unintentional errors occurred in the column/row reference model version; most (23/24) were due to incorrect cell references. Overall, >20% of model spreadsheet cells had material unintentional errors. When examining error impact along the HIV care continuum, the percentage difference between versions with and without unintentional errors ranged from +3% to +16% (named single cells), +26% to +76% (column/row reference), and 0% (named matrices). CONCLUSIONS: Standard error-checking techniques may not identify all errors in spreadsheet-based models. Comparing parallel model versions can aid in identifying unintentional errors and promoting reliable model projections, particularly when resources are limited. PMID- 29570738 TI - The author who wasn't there? Fairness and attribution in publications following access to population biobanks. AB - We conducted a document analysis that explored publication ethics and authorship in the context of population biobanks from both a theoretical (e.g. normative documents) and practical (e.g. biobank-specific documentation) perspective. The aim was to provide an overview of the state of authorship attribution in population biobanks and attempt to fill the gap in discussions around the issue. Our findings demonstrate that the most common approach adopted in both the normative and biobank-specific documentation is acknowledgment. A co-authorship approach was second and highlighted concerns surrounding the fairness of imposing authorship of the scientific leadership as a condition to access data and biosamples, as well as the alignment with the International Committee of Medical Journal Editors' criteria such as what is deemed a significant contribution and how to ensure accountability. Based on these findings, we propose a three-prong approach, that may be cumulative, to address the issue of authorship attribution in the context of population biobanks, namely 1) the biobank should be appropriately acknowledged; 2) an invitation for co-authorship should be made based on the spirit of collaboration and provided a substantial contribution has been made; and 3) a citation/referencing option should be available. PMID- 29570739 TI - Development of an improved RT-qPCR Assay for detection of Japanese encephalitis virus (JEV) RNA including a systematic review and comprehensive comparison with published methods. AB - BACKGROUND: Japanese encephalitis virus (JEV) is a major cause of encephalitis in Asia, and the commonest cause of mosquito-borne encephalitis worldwide. Detection of JEV RNA remains challenging due to the characteristic brief and low viraemia, with 0-25% of patients positive, and the mainstay of diagnosis remains detection of anti-JEV IgM antibody. METHODS: We performed a systematic review of published RT-PCR protocols, and evaluated them in silico and in vitro alongside new primers and probes designed using a multiple genome alignment of all JEV strains >9,000nt from GenBank, downloaded from the NCBI website (November 2016). The new assays included pan-genotype and genotype specific assays targeting genotypes 1 and 3. RESULTS: Ten RT-qPCR assays were compared, a pre-existing in-house assay, three published assays and six newly designed assays, using serial RNA dilutions. We selected three assays, one published and two novel assays, with the lowest limit of detection (LOD) for further optimisation and validation. One of the novel assays, detecting NS2A, showed the best results, with LOD approximately 4 copies/ reaction, and no cross-reaction on testing closely related viruses in the JEV serocomplex, West Nile Virus and St. Louis Virus. The optimised assays were validated in consecutive patients with central nervous system infections admitted to hospitals in Laos, testing paired CSF and serum samples. CONCLUSIONS: We succeeded in developing a JEV specific RT-qPCR assay with at least 1 log10 improved sensitivity as compared to existing assays. Further evaluation is required, field-testing the assay in a larger group of patients. PMID- 29570740 TI - Identifying bedrest using 24-h waist or wrist accelerometry in adults. AB - OBJECTIVES: To adapt and refine a previously-developed youth-specific algorithm to identify bedrest for use in adults. The algorithm is based on using an automated decision tree (DT) analysis of accelerometry data. DESIGN: Healthy adults (n = 141, 85 females, 19-69 years-old) wore accelerometers on the waist, with a subset also wearing accelerometers on the dominant wrist (n = 45). Participants spent ~24-h in a whole-room indirect calorimeter equipped with a force-platform floor to detect movement. METHODS: Minute-by-minute data from recordings of waist-worn or wrist-worn accelerometers were used to identify bedrest and wake periods. Participants were randomly allocated to development (n = 69 and 23) and validation (n = 72 and 22) groups for waist-worn and wrist-worn accelerometers, respectively. The optimized DT algorithm parameters were block length, threshold, bedrest-start trigger, and bedrest-end trigger. Differences between DT classification and synchronized objective classification by the room calorimeter to bedrest or wake were assessed for sensitivity, specificity, and accuracy using a Receiver Operating Characteristic (ROC) procedure applied to 1 min epochs (n = 92,543 waist; n = 30,653 wrist). RESULTS: The optimal algorithm parameter values for block length were 60 and 45 min, thresholds 12.5 and 400 counts/min, bedrest-start trigger 120 and 400 counts/min, and bedrest-end trigger 1,200 and 1,500 counts/min, for the waist and wrist-worn accelerometers, respectively. Bedrest was identified correctly in the validation group with sensitivities of 0.819 and 0.912, specificities of 0.966 and 0.923, and accuracies of 0.755 and 0.859 by the waist and wrist-worn accelerometer, respectively. The DT algorithm identified bedrest/sleep with greater accuracy than a commonly used automated algorithm (Cole-Kripke) for wrist-worn accelerometers (p<0.001). CONCLUSIONS: The adapted DT accurately identifies bedrest in data from accelerometers worn by adults on either the wrist or waist. The automated bedrest/sleep detection DT algorithm for both youth and adults is openly accessible as a package "PhysActBedRest" for the R-computer language. PMID- 29570741 TI - Time- and depth-wise trophic niche shifts in Antarctic benthos. AB - Climate change is expected to affect resource-consumer interactions underlying stability in polar food webs. Polar benthic organisms have adapted to the marked seasonality characterising their habitats by concentrating foraging and reproductive activity in summer months, when inputs from sympagic and pelagic producers increase. While this enables the persistence of biodiverse food webs, the mechanisms underlying changes in resource use and nutrient transfer are poorly understood. Thus, our understanding of how temporal and spatial variations in the supply of resources may affect food web structure and functioning is limited. By means of C and N isotopic analyses of two key Antarctic benthic consumers (Adamussium colbecki, Bivalvia, and Sterechinus neumayeri, Echinoidea) and Bayesian mixing models, we describe changes in trophic niche and nutrient transfer across trophic levels associated with the long- and short-term diet and body size of specimens sampled in midsummer in both shallow and deep waters. Samplings occurred soon after the sea-ice broke up at Tethys Bay, an area characterised by extreme seasonality in sea-ice coverage and productivity in the Ross Sea. In the long term, the trophic niche was broader and variation between specimens was greater, with intermediate-size specimens generally consuming a higher number of resources than small and large specimens. The coupling of energy channels in the food web was consequently more direct than in the short term. Sediment and benthic algae were more frequently consumed in the long term, before the sea-ice broke up, while consumers specialised on sympagic algae and plankton in the short term. Regardless of the time scale, sympagic algae were more frequently consumed in shallow waters, while plankton was more frequently consumed in deep waters. Our results suggest a strong temporal relationship between resource availability and the trophic niche of benthic consumers in Antarctica. Potential climate-driven changes in the timing and quality of nutrient inputs may have profound implications for the structure of polar food webs and the persistence of their constituent species, which have adapted their trophic niches to a highly predictable schedule of resource inputs. PMID- 29570744 TI - Identification of a robust subpathway-based signature for acute myeloid leukemia prognosis using an miRNA integrated strategy. AB - Acute myeloid leukemia (AML) is a heterogeneous disease, and survival signatures are urgently needed to better monitor treatment. MiRNAs displayed vital regulatory roles on target genes, which was necessary involved in the complex disease. We therefore examined the expression levels of miRNAs and genes to identify robust signatures for survival benefit analyses. First, we reconstructed subpathway graphs by embedding miRNA components that were derived from low throughput miRNA-gene interactions. Then, we randomly divided the data sets from The Cancer Genome Atlas (TCGA) into training and testing sets, and further formed 100 subsets based on the training set. Using each subset, we identified survival related miRNAs and genes, and identified survival subpathways based on the reconstructed subpathway graphs. After statistical analyses of these survival subpathways, the most robust subpathways with the top three ranks were identified, and risk scores were calculated based on these robust subpathways for AML patient prognoses. Among these robust subpathways, three representative subpathways, path: 05200_10 from Pathways in cancer, path: 04110_20 from Cell cycle, and path: 04510_8 from Focal adhesion, were significantly associated with patient survival in the TCGA training and testing sets based on subpathway risk scores. In conclusion, we performed integrated analyses of miRNAs and genes to identify robust prognostic subpathways, and calculated subpathway risk scores to characterize AML patient survival. PMID- 29570742 TI - Impact of acute-phase complications and interventions on 6-month survival after stroke. A prospective observational study. AB - The outcome of stroke patients is complex and multidimensional. We evaluated the impact of acute-phase variables, including clinical state, complications, resource use and interventions, on 6-month survival after first-ever stroke, taking into account baseline conditions exerting a possible effect on outcome. As part of a National Research Program, we performed a prospective observational study of acute stroke patients in four Italian Regions. Consecutive patients admitted for a period of 3 months to the emergency rooms of participating hospitals were included. A total of 1030 patients were enrolled (median age 76.0 years, 52.1% males). At 6 months, 816 (79.2%) were alive, and 164 (15.9%) deceased. Survival status at the 6-month follow-up was missing for 50 (4.9%). Neurological state in the acute phase was significantly worse in patients deceased at 6 months, who showed also higher frequency of acute-phase complications. Cox regression analysis adjusted for demographics, pre-stroke function, baseline diseases and risk factors, indicated as significant predictors of 6-month death altered consciousness (HR, 1.70; 95% CI, 1.14-2.53), total anterior circulation infarct (HR, 2.13; 95% CI, 1.44-3.15), hyperthermia (HR, 1.70; 95% CI, 1.18-2.45), pneumonia (HR, 1.76; 95% CI, 1.18-2.61), heart failure (HR, 2.87; 95% CI, 1.34-6.13) and nasogastric feeding (HR, 2.35; 95% CI, 1.53 3.60), while antiplatelet therapy during acute phase (HR, 0.56; 95% CI, 0.39 0.79), and early mobilisation (HR, 0.55; 95% CI, 0.36-0.84) significantly increased 6-month survival. In a prospective observational study, stroke severity and some acute-phase complications, potentially modifiable, significantly increased the risk of 6-month death, independently of baseline variables. Early mobilisation positively affected survival, highlighting the role of early rehabilitation after stroke.

AB - Next generation sequencing (NGS) is becoming increasingly integrated into oncological practice and clinical research. NGS methods have also provided evidence for clonal evolution of cancers during disease progression and treatment. The number of variants associated with response to specific therapeutic agents keeps increasing. However, the identification of novel driver mutations as opposed to passenger (phenotypically silent or clinically irrelevant) mutations remains a major challenge. We conducted targeted exome sequencing of advanced solid tumors from 44 pre-treated patients with solid tumors including breast, colorectal and lung carcinomas, neuroendocrine tumors, sarcomas and others. We catalogued established driver mutations and putative new drivers as predicted by two distinct algorithms. The established drivers we detected were consistent with published observations. However, we also detected a significant number of mutations with driver potential never described before in each tumor type we studied. These putative drivers belong to key cell fate regulatory networks, including potentially druggable pathways. Should our observations be confirmed, they would support the hypothesis that new driver mutations are selected by treatment in clinically aggressive tumors, and indicate a need for longitudinal genomic testing of solid tumors to inform second line cancer treatment.

AB - Powdery mildew is a widespread fungal plant disease that can cause significant losses in many crops. Some MLO genes (Mildew resistance locus O) have proved to confer a durable resistance to powdery mildew in several species. Resistance granted by the MLO gene family members has prompted an increasing interest in characterizing these genes and implementing their use in plant breeding. Lentil (Lens culinaris Medik.) is a widely grown food legume almost exclusively consumed as dry seed with an average world production of 4.5 million tons. Powdery mildew causes severe losses on certain lentil cultivars under particular environmental conditions. Data mining of the lentil CDC Redberry draft genome allowed to identify up to 15 gene sequences with homology to known MLO genes, designated as LcMLOs. Further characterization of these gene sequences and their deduced protein sequences demonstrated conformity with key MLO protein characteristics such as the presence of transmembrane and calmodulin binding domains, as well as that of other conserved motifs. Phylogenetic and other comparative analyses revealed that LcMLO1 and LcMLO3 are the most likely gene orthologs related to powdery mildew response in other species, sharing a high similarity with other known resistance genes of dicot species, such as pea PsMLO1 and Medicago truncatula MtMLO1 and MtMLO3. Sets of primers were designed as tools to PCR amplify the genomic sequences of LcMLO1 and LcMLO3, also to screen lentil germplasm in search of resistance mutants. Primers were used to obtain the complete sequences of these two genes in all of the six wild lentil relatives. Respective to each gene, all Lens sequences shared a high similarity. Likewise, we used these primers to screen a working collection of 58 cultivated and 23 wild lentil accessions in search of length polymorphisms present in these two genes. All these data widen the insights on this gene family and can be useful for breeding programs in lentil and close related species.

AB - Foot and mouth disease (FMD) has devastated the cattle industry in Sri Lanka many times in the past. Despite its seriousness, limited attempts have been made to understand the disease to ameliorate its effects-current recommendation for vaccines being based solely on immunological assessments rather than on molecular identification. The general belief is that the cattle population in Sri Lanka acquired the FMD virus (FMDV) strains via introductions from India. However, there could be endemic FMDV lineages circulating in Sri Lanka. To infer the phylogenetic relationships of the FMDV strains in the island, we sequenced the VP1 genomic region of the virus isolates collected during the 2014 outbreak together with a few reported cases in 2012 and 1997 and compared them to VP1 sequences from South Asia. The FMDV strains collected in the 2014 outbreak belonged to the lineage, Ind-2001d, of the topotype, ME-SA. The strains collected in 2012 and 1997 belonged to another lineage called 'unnamed' by the World Reference Laboratory for Foot and Mouth Disease (WRLFMD). Based on the present analysis, we designate the lineage 'unnamed' as Srl-97 which we found endemic to Sri Lanka. The evolutionary rates of Srl-97 and Ind-2001d in Sri Lanka were estimated to be 0.0004 and 0.0046 substitutions/site/year, respectively, suggesting that Srl-97 evolves slowly. PMID- 29570747 TI - Dogs (Canis familiaris) stick to what they have learned rather than conform to their conspecifics' behavior. AB - In recent years, an increasing number of studies has investigated majority influence in nonhuman animals. However, due to both terminological and methodological issues, evidence for conformity in nonhuman animals is scarce and controversial. Preliminary evidence suggests that wild birds, wild monkeys, and fish show conformity, that is, forgoing personal information in order to copy the majority. By contrast, chimpanzees seem to lack this tendency. The present study is the first to examine whether dogs (Canis familiaris) show conformity. Specifically, we tested whether dogs conform to a majority of conspecifics rather than stick to what they have previously learned. After dogs had acquired a behavioral preference via training (i.e., shaping), they were confronted with counter-preferential behavior of either no, one or three conspecifics. Traditional frequentist analyses show that the dogs' behavior did not differ significantly between the three conditions. Complementary Bayesian analyses suggest that our data provide moderate evidence for the null hypothesis. In conclusion, our results suggest that dogs stick to what they have learned rather than conform to the counter-preferential behavior of others. We discuss the possible statistical and methodological limitations of this finding. Furthermore, we take a functional perspective on conformity and discuss under which circumstances dogs might show conformity after all. PMID- 29570748 TI - Inertial Properties of Football Helmets. AB - The inertial properties of a helmet play an important role in both athletic performance and head protection. In this study, we measured the inertial properties of 37 football helmets, a National Operating Committee on Standards for Athletic Equipment (NOCSAE) size 71/4 headform, and a 50th percentile male Hybrid III dummy head. The helmet measurements were taken with the helmets placed on the Hybrid III dummy head. The center of gravity and moment of inertia were measured about six axes (x, y, z, xy, yz, and xz), allowing for a complete description of the inertial properties of the head and helmets. Total helmet mass averaged 1834+/-231 g, split between the shell (1377+/-200 g) and the facemask (457+/-101 g). On average, the football helmets weighed 41+/-5% as much as the Hybrid III dummy head. The center of gravity of the helmeted head was 1.1+/-3.0 mm anterior and 10.3+/-1.9 mm superior to the center of gravity of the bare head. The moment of inertia of the helmeted head was approximately 2.2+/-0.2 times greater than the bare head about all axes. PMID- 29570749 TI - Influence of the musculotendon dynamics on the muscle force sharing problem of the shoulder ? a fully inverse dynamics approach. AB - Most dynamic simulations are based on inverse dynamics, being the time-dependent physiological nature of the muscle properties rarely considered due to numerical challenges. Since the influence of muscle physiology on the consistency of inverse dynamics simulations remains unclear, the purpose of the present study is to evaluate the computational efficiency and biological validity of four musculotendon models that differ in the simulation of the muscle activation and contraction dynamics. Inverse dynamic analyses are performed using a spatial musculoskeletal model of the upper limb. The muscle force sharing problem is solved for 5 repetitions of unloaded and loaded motions of shoulder abduction and shoulder flexion. The performance of the musculotendon models is evaluated by comparing muscle activation predictions with EMG signals, measured synchronously with motion for 11 muscles, and the glenohumeral joint reaction forces estimated numerically with those measured in vivo. The results show similar muscle activations for all muscle models. Overall, high cross-correlations are computed between muscle activations and the EMG signals measured for all movements analyzed, which provides confidence in the results. The glenohumeral joint reaction forces estimated compare well with those measured in vivo, but the influence of the muscle dynamics is found to be negligible. In conclusion, for slow-speed, standard movements of the upper limb, as those studied here, the activation and musculotendon contraction dynamics can be neglected in inverse dynamic analyses without compromising the prediction of muscle and joint reaction forces.

AB - Much of our understanding of the role of elbow ligaments to overall joint biomechanics has been developed through in vitro cadaver studies using joint motion simulators. The principle of superposition can be used to indirectly compute the force contributions of ligaments during prescribed motions. Previous studies have analyzed the contribution of different soft tissue structures to the stability of human elbow joints, but have limitations in evaluating the loads sustained by those tissues. This manuscript introduces a unique, hybrid experimental-computational technique for measuring and simulating the biomechanical contributions of ligaments to elbow joint kinematics and stability. In vitro testing of cadaveric joints is enhanced by the incorporation of fully parametric virtual ligaments, which are used in place of the native joint stabilizers to characterize the contribution of elbow ligaments during simple flexion-extension motions using the principle of superposition. Our results support previously reported findings that the anterior medial collateral ligament and the radial collateral ligament are the primary soft tissue stabilizers for the elbow joint. Tuned virtual ligaments employed in this study were able to restore the kinematics and laxity of elbows to within 2 degrees of native joint behavior. The hybrid framework presented in this study demonstrates promising capabilities in measuring the biomechanical contribution of ligamentous structures to joint stability. PMID- 29570753 TI - The Relationship Between Speech, Language, and Phonological Awareness in Preschool-Age Children With Developmental Disabilities. AB - Purpose: A number of intrinsic factors, including expressive speech skills, have been suggested to place children with developmental disabilities at risk for limited development of reading skills. This study examines the relationship between these factors, speech ability, and children's phonological awareness skills. Method: A nonexperimental study design was used to examine the relationship between intrinsic skills of speech, language, print, and letter sound knowledge to phonological awareness in 42 children with developmental disabilities between the ages of 48 and 69 months. Hierarchical multiple regression was done to determine if speech ability accounted for a unique amount of variance in phonological awareness skill beyond what would be expected by developmental skills inclusive of receptive language and print and letter-sound knowledge. Results: A range of skill in all areas of direct assessment was found. Children with limited speech were found to have emerging skills in print knowledge, letter-sound knowledge, and phonological awareness. Speech ability did not predict a significant amount of variance in phonological awareness beyond what would be expected by developmental skills of receptive language and print and letter-sound knowledge. Conclusion: Children with limited speech ability were found to have receptive language and letter-sound knowledge that supported the development of phonological awareness skills. This study provides implications for practitioners and researchers concerning the factors related to early reading development in children with limited speech ability and developmental disabilities. PMID- 29570752 TI - Selecting Sensitive Parameter Subsets in Dynamical Models With Application to Biomechanical System Identification. AB - Estimating many parameters of biomechanical systems with limited data may achieve good fit but may also increase 95% confidence intervals in parameter estimates. This results in poor identifiability in the estimation problem. Therefore, we propose a novel method to select sensitive biomechanical model parameters that should be estimated, while fixing the remaining parameters to values obtained from preliminary estimation. Our method relies on identifying the parameters to which the measurement output is most sensitive. The proposed method is based on the Fisher information matrix (FIM). It was compared against the nonlinear least absolute shrinkage and selection operator (LASSO) method to guide modelers on the pros and cons of our FIM method. We present an application identifying a biomechanical parametric model of a head position-tracking task for ten human subjects. Using measured data, our method (1) reduced model complexity by only requiring five out of twelve parameters to be estimated, (2) significantly reduced parameter 95% confidence intervals by up to 89% of the original confidence interval, (3) maintained goodness of fit measured by variance accounted for (VAF) at 82%, (4) reduced computation time, where our FIM method was 164 times faster than the LASSO method, and (5) selected similar sensitive parameters to the LASSO method, where three out of five selected sensitive parameters were shared by FIM and LASSO methods. PMID- 29570754 TI - Computational Fluid Dynamics of Vascular Disease in Animal Models. AB - Recent applications of computational fluid dynamics (CFD) applied to the cardiovascular system have demonstrated its power in investigating the impact of hemodynamics on disease initiation, progression, and treatment outcomes. Flow metrics such as pressure distributions, wall shear stresses (WSS), and blood velocity profiles can be quantified to provide insight into observed pathologies, assist with surgical planning, or even predict disease progression. While numerous studies have performed simulations on clinical human patient data, it often lacks prediagnosis information and can be subject to large intersubject variability, limiting the generalizability of findings. Thus, animal models are often used to identify and manipulate specific factors contributing to vascular disease because they provide a more controlled environment. In this review, we explore the use of CFD in animal models in recent studies to investigate the initiating mechanisms, progression, and intervention effects of various vascular diseases. The first section provides a brief overview of the CFD theory and tools that are commonly used to study blood flow. The following sections are separated by anatomical region, with the abdominal, thoracic, and cerebral areas specifically highlighted. We discuss the associated benefits and obstacles to performing CFD modeling in each location. Finally, we highlight animal CFD studies focusing on common surgical treatments, including arteriovenous fistulas (AVF) and pulmonary artery grafts. The studies included in this review demonstrate the value of combining CFD with animal imaging and should encourage further research to optimize and expand upon these techniques for the study of vascular disease.

AB - Quantifying the mechanical properties of the iris is important, as it provides insight into the pathophysiology of glaucoma. Recent ex vivo studies have shown that the mechanical properties of the iris are different in glaucomatous eyes as compared to normal ones. Notwithstanding the importance of the ex vivo studies, such measurements are severely limited for diagnosis and preclude development of treatment strategies. With the advent of detailed imaging modalities, it is possible to determine the in vivo mechanical properties using inverse finite element (FE) modeling. An inverse modeling approach requires an appropriate objective function for reliable estimation of parameters. In the case of the iris, numerous measurements such as iris chord length (CL) and iris concavity (CV) are made routinely in clinical practice. In this study, we have evaluated five different objective functions chosen based on the iris biometrics (in the presence and absence of clinical measurement errors) to determine the appropriate criterion for inverse modeling. Our results showed that in the absence of experimental measurement error, a combination of iris CL and CV can be used as the objective function. However, with the addition of measurement errors, the objective functions that employ a large number of local displacement values provide more reliable outcomes. PMID- 29570757 TI - Simulation of Airflow in an Idealized Emphysematous Human Acinus. AB - Emphysema is the permanent enlargement of air spaces in the respiratory regions of the lung due to destruction of the inter-alveolar septa. The progressive coalescence of alveoli and alveolar ducts into larger airspaces leads to the disruption of normal airway wall motion and airflow rates within the pulmonary acinus. To contribute to the understanding of the individual effects of emphysema during its earliest stages, computational fluid dynamics simulations of airflow in mathematically-derived models of the pulmonary acinus were performed. The here generated computational domain consists of two generations of alveolar ducts within the pulmonary acinus, with alveolar geometries approximated as closely packed, fourteen-sided polygons. Physiologically realistic airflow rates and wall motions were used to study airflow patterns within subsequent generations of alveolar ducts during the inspiratory and expiratory phases of the breathing cycle. The effects of progressive emphysema on the airway wall motion and flow rates were simulated by sequentially removing all alveolar septa within each alveolar duct. Parametric studies were presented to independently assess the relative influence of progressive septal destruction of airway motion and flow rates. The results illustrate that septal destruction lowers the flow resistance through the alveolar ducts but has little influence on the mass transport of oxygen into the alveoli. Septal destruction has a net effect on the flow field by favoring the development of recirculatory flow patterns in individual alveoli. PMID- 29570758 TI - Benchmark for Numerical Models of Stented Coronary Bifurcation Flow. AB - In-stent restenosis ails many patients who have undergone stenting. When the stented artery is a bifurcation, the intervention is particularly critical because of the complex stent geometry involved in these structures. Computational fluid dynamics (CFD) has been shown to be an effective approach when modeling blood flow behavior and understanding the mechanisms that underlie in-stent restenosis. However, these CFD models require validation through experimental data in order to be reliable. It is with this purpose in mind that we performed particle image velocimetry (PIV) measurements of velocity fields within flows through a simplified coronary bifurcation. Although the flow in this simplified bifurcation differs from the actual blood flow, it emulates the main fluid dynamic mechanisms found in hemodynamic flow. Experimental measurements were performed for several stenting techniques in both steady and unsteady flow conditions. The test conditions were strictly controlled, and uncertainty was accurately predicted. The results obtained in this research represent readily accessible, easy to emulate, detailed velocity fields and geometry, and they have been successfully used to validate our numerical model. These data can be used as a benchmark for further development of numerical CFD modeling in terms of comparison of the main flow pattern characteristics. PMID- 29570759 TI - Using Ceramic-on-Ceramic Bearings in Total Hip Arthroplasty Necessitating 44- or 46-mm Metal Shells. AB - Ceramic-on-ceramic articulation shows the lowest wear, with a low incidence of osteolysis. A small cup limits options regarding liner thickness and femoral implant size. The purpose of this study was to evaluate the safety of a 4-mm thick ceramic liner and the outcomes of cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing at mid- to long-term follow-up. Between May 2003 and June 2008, 80 patients (88 hips) who had hip osteoarthritis and a hypoplastic acetabulum underwent cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing. Sixty-eight of these patients (76 hips) were followed for an average of 8 years. The ceramic-related complications, clinical and radiological results, and Kaplan Meier survivorship of these patients were evaluated. Mean Harris hip score had improved to 88 points (range, 49-100 points) at final follow-up. No ceramic fractures occurred during follow-up. All acetabular and femoral prostheses had bone ingrowth, and there was no measurable wear in any hip. In 1 patient, a radiolucent lesion occurred around the acetabular cup. Two hips underwent revision because of periprosthetic fractures. The survival rates of the acetabular cups and the femoral stems were 100% and 97.4%, respectively. The thin (4 mm) ceramic liner did not increase the risk of ceramic fracture and did not affect the mid- to long-term results and survival of cementless total hip arthroplasty using 44- or 46-mm metal shells.

AB - Aspirin and unfractionated heparin (UH) are accepted options for venous thromboembolism (VTE) prophylaxis after total joint arthroplasty (TJA). The use of aspirin in addition to UH in preventing VTE after TJA has yet to be studied. The primary objective of this study was to determine VTE rates in patients receiving aspirin monotherapy and those receiving aspirin and UH combination therapy immediately following TJA. A TJA database from a single hospital system was retrospectively reviewed to identify all patients who underwent primary hip or knee arthroplasty from 2013 to 2016. Patients were divided into 3 groups based on postoperative VTE chemoprophylaxis: aspirin only, aspirin with 1 dose of UH, and aspirin with multiple doses of UH. There were 5350 patients included: 1024 aspirin only, 1695 aspirin plus 1 dose of UH, and 2631 aspirin plus multiple doses of UH. Deep venous thrombosis and pulmonary embolus rates did not vary significantly between groups (deep venous thrombosis: 1.1%, 0.9%, and 1.2%, respectively, P=.701; pulmonary embolus: 0.3%, 0.3%, and 0.2%, respectively, P=.894). Transfusion rates were significantly greater with 1 dose of UH (1.8%) and multiple doses of UH (4.3%) compared with aspirin only (0.9%) (P<.001). Additionally, the postoperative hemoglobin decreased significantly more postoperatively with the use of UH (P<.001). Aspirin and UH combination therapy did not decrease VTE incidence compared with aspirin monotherapy. Additionally, there was greater perioperative blood loss and an increased rate of blood transfusion in patients receiving UH. On the basis of these findings, the authors do not recommend UH as an additional mode of VTE prophylaxis when prescribing aspirin after elective TJA. [Orthopedics. 2018; 41(3):171-176.].

AB - Forged composites of raw particulate unsintered hydroxyapatite/poly-L-lactide (F u-HA/PLLA) devices possess high mechanical strength, bioactivity, and radio opacity. The aim of this study was to assess the efficacy of F-u-HA/PLLA screws in the treatment of lateral tibial condylar fractures. From January 2005 to December 2010, a total of 7 patients with displaced closed lateral tibial condylar fractures (Schatzker type II) were treated using F-u-HA/PLLA screws. Open reduction and internal fixation was performed using 2 or 3 F-u-HA/PLLA screws. After surgery, weight bearing was not allowed for 6 weeks. Range of motion exercise was initiated after removal of the plaster splint. Radiographs were evaluated for fracture healing, joint depression, and the radioopacity of F u-HA/PLLA screws. Clinical outcomes and postoperative complications were also assessed. Average follow-up was 44 months. All fractures were successfully healed. Average values for joint depression were 4.7 mm (range, 2-9 mm) preoperatively, 0.4 mm (range, 0-1 mm) postoperatively, and 0.4 mm (range, 0-1 mm) at final follow-up. Whole shadows of F-u-HA/PLLA screws were observed during the follow-up period. Breakage of screws, osteolysis, and a radiolucent zone around the screws were not observed at final follow-up. Average knee flexion and extension were 134 degrees (range, 110 degrees to 150 degrees ) and -1 degrees (range, -10 degrees to 0 degrees ), respectively. No patient had wound infection, late aseptic tissue response, or foreign body reaction postoperatively. None of the patients reported pain at final follow-up. These results suggest that F-u-HA/PLLA screws could be an alternative option for the treatment of lateral tibial condylar fractures. [Orthopedics. 2018; 41(3):e365 e368.]. PMID- 29570762 TI - The Proximal and Distal Femoral Canal Geometry Influences Cementless Stem Anchorage and Revision Hip and Knee Implant Stability. AB - Although cementless revision arthroplasty of the hip has become the gold standard, revision arthroplasty of the distal femur is controversial. This study evaluated the anchoring principles of different femoral revision stem designs in extended bone defect situations, taking into account the anatomical conditions of the proximal and distal femur, and the resulting primary stability. Cementless press-fit stems of 4 different designs were implanted in synthetic femurs. The specimens were analyzed by computed tomography and were tested considering axial/torsional stiffness and migration resistance. Different stem designs anchored in different femoral canal geometries achieved comparable primary stability. Despite considerably different anchorage lengths, no difference in migration behavior or stiffness was found. Both in the distal femur and in the proximal femur, the conical stems showed a combination of conical and 3-point anchorage. Regarding the cylindrical stem tested, a much shorter anchorage length was sufficient in the distal femur to achieve comparable primary stability. In the investigated osseous defect model, the stem design (conical vs cylindrical), not the geometry of the femoral canal (proximal vs distal), was decisive regarding the circumferential anchorage length. For the conical stems, it can be postulated that there are reserves available for achieving a conical-circular fixation as a result of the large contact length. For the cylindrical stems, only a small reserve for a stable anchorage can be assumed. [Orthopedics. 2018; 41(3):e369-e375.].

AB - Little research has been conducted evaluating surgical trends during the past 10 years and subsequent procedure risk factors for patients undergoing bone-blocking procedures for the treatment of anterior shoulder instability. The Statewide Planning and Research Cooperative System database was queried between 2003 and 2014 to identify patients undergoing soft tissue or bone-blocking procedures for anterior shoulder instability in New York. Patient demographics and 1-year subsequent procedures were analyzed. Multivariate logistic regression analyses were conducted to identify 1-year subsequent procedure risk factors. From 2003 through 2014, a total of 540 patients had Latarjet procedures performed. During this period, the volume of Latarjet procedures increased by 950%, from 12 procedures in 2003 to 126 procedures in 2014. The volume of open Bankart repairs declined by 77%; arthroscopic Bankart repairs fluctuated, being up (328%) between 2003 and 2012 and then down (6%) between 2012 and 2014. Of the 540 patients, 2.4% (13 of 540) required intervention for recurrent shoulder instability events. Age older than 20 years and workers' compensation were identified as independent risk factors for reoperation. The number of bone-blocking procedures, such as the Latarjet, has increased by nearly 1000% during the past decade in New York. Only 2.4% (13 of 540) of the patients had subsequent shoulder instability interventions. [Orthopedics. 2018; 41(3):e389-e394.]. PMID- 29570764 TI - Atypical Mycobacterial Infections of the Upper Extremity. AB - Atypical mycobacterial infections of upper extremity synovial-lined structures are often misdiagnosed and unrecognized. Despite an increasing incidence, lack of physician awareness of these pathogens may result in considerable delay in diagnosis and management, potentially leading to permanent disability. The authors conducted a literature review and analyzed 31 cases of penetrating atypical mycobacterial infection to better understand the clinical characteristics and to evaluate their posttreatment complication rate compared with available literature. Medical records for culture-positive cases of tenosynovial or intra-articular atypical mycobacterial infections of the upper extremity that were treated were retrospectively reviewed. Treatment outcomes were analyzed against published case reviews and case series. Thirty-one cases of penetrating atypical mycobacterial infection were identified. Mycobacterium marinum (n=11) was the most common organism and was associated with aquatic exposure. Twenty-eight cases received empiric treatment, 17 of which received contraindicated treatment. Patients saw an average of 5 physicians prior to receiving an accurate diagnosis, and the mean time to diagnosis was 10 months. All cases received antibiotic treatment in addition to surgical management. Twenty cases (68%) failed treatment outcomes. Delay in diagnosis and inappropriate management of atypical mycobacterial infections may lead to a treatment failure rate that is higher than what has been reported in the literature. Mycobacterium avium and M fortuitum had significantly higher failure rates than other organisms. A high index of suspicion is required to make a diagnosis and prevent residual disability.

AB - Fresh allograft transplantation of osteochondral defects restores functional articular cartilage and subchondral bone; however, rapid loss of chondrocyte viability during storage and osteoclast-mediated bone resorption at the graft host interface after transplantation negatively impact outcomes. The authors present a pilot study evaluating the in vitro and in vivo impact of augmenting storage media with bisphosphonates. Forty cylindrical osteochondral cores were harvested from femoral condyles of human cadaveric specimens and immersed in either standard storage media or storage media supplemented with nitrogenated or non-nitrogenated bisphosphonates. Maintenance of graft structure and chondrocyte viability were assessed at 3 time points. A miniature swine trochlear defect model was used to evaluate the influence of bisphosphonate-augmented storage media on in vivo incorporation of fresh osteochondral tissue, which was quantified via MUCT and decalcified histology. In the in vitro study, Safranin O/Fast Green staining showed that both low- and high-dose nitrogenated-treated grafts retained chondrocyte viability and cartilage matrix for up to 43 days of storage. Allografts stored in nitrogenated-augmented storage media showed both MUCT and histologic evidence of enhanced in vivo bony and cartilaginous incorporation in the miniature swine trochlear defect model. Several preclinical studies have shown the potential for enhanced storage of fresh osteochondral allografts via additions of relatively common drugs and biomolecules. This study showed that supplementing standard storage media with nitrogenated bisphosphonates may improve maintenance of chondrocyte viability and graft structure during cold storage as well as enhance in vivo osseous and cartilaginous incorporation of the graft.

Patient results were assessed with Tegner, Lysholm, and visual analog scale scores; healing criteria; magnetic resonance imaging; and complication rates. Mean follow-up was 38.2 months. Tegner and Lysholm scores improved postoperatively in both groups (all P<.01) and were similar for the 2 groups (all P>.05). Visual analog scale scores were reduced postoperatively in both groups (P<.01) and similar for the 2 groups (P>.05). Healing rates and complication rates did not differ between the 2 groups (all P>.05), but healing on magnetic resonance imaging was better in group A than group B (P<.05). The repair of chronic tears of the anterior horn of the lateral meniscus can lead to good clinical outcomes and a satisfactory success rate. Covering the repair site with an infrapatellar pedicle fat flap may improve meniscal healing and does not increase the complication rate. [Orthopedics. 2018; 41(3):e360-e364.].

Nucleotides 505-507 and 524-526 form a pseudo-knot and its distortion affects ribosome function. Helix 18 isolated from the ribosome context is thus an interesting fragment to investigate the structural properties and folding of RNA with pseudo-knots. With all-atom molecular dynamics simulations, spectroscopic and gel electrophoresis experiments, we investigated thermodynamics of helix 18, with a focus on its pseudo-knot. In solution studies at ambient conditions we observed dimerization of helix 18. We proposed that the loop, containing nucleotides forming the pseudo-knot, interacts with another monomer of helix 18. The native dimer is difficult to break but introducing mutations in the pseudo knot indeed assured a monomeric form of helix 18. Molecular dynamics simulations at 310 K confirmed the stability of the pseudo-knot but at elevated temperatures this pseudo-knot was the first part of helix 18 to lose the hydrogen bond pattern. To further determine helix 18 stability, we analyzed the interactions of helix 18 with short oligomers complementary to a nucleotide stretch containing the pseudo-knot. The formation of higher-order structures by helix 18 impacts hybridization efficiency of peptide nucleic acid and 2'-O methyl RNA oligomers.

AB - Previous research demonstrated hypoactivity of the HPA axis in children with attention-deficit/hyperactivity disorder (ADHD) or externalizing symptoms. We analyzed the predictive association between the long-term HPA axis activity and increasing symptoms of ADHD in the preschool period. The sample consisted of n = 125 4-year-old children and their families (including n = 64 children with elevated ADHD symptoms). ADHD symptoms were assessed by a structured clinical interview with the mother and by parent- and teacher-report questionnaires. The long-term HPA axis activity was assessed by the hair cortisol concentration (HCC) (over a 3-month period). After controlling for potential confounders, low HCC predicted an increase in ADHD symptoms between the age of 4 and 5 years. Exploration of gender effects revealed that cross-sectional and predictive associations were significant in boys but not in girls. Low HCC might thus be regarded as an early marker of a possibly gender-related developmental pathway to ADHD.

AB - T cell immunoglobulin domain and mucin domain-containing molecule-3 (Tim-3), a member of the immunoglobulin superfamily, has been shown to play a crucial role in host adaptive immunity and tolerance. However, its role in kidney ischaemia reperfusion injury (IRI) remains unknown. In this study, we investigated the role and mechanism of Tim-3 signalling after kidney IRI. In an established murine model of kidney IRI, we found that Tim-3 expression is enhanced on monocytes/macrophages. Anti-Tim-3 antibody RMT3-23 ameliorates biochemical and histological kidney injury, reduces apoptosis and decreases macrophage infiltration and cytokine production in ischaemic kidneys. Cell culture experiments also demonstrated that the role of Tim-3 in IRI-induced macrophage activation leads to the secretion of proinflammatory cytokines and chemokines. In addition, Toll-like receptor (TLR)-4 and Nod-like receptor (NLR) family CARD domain-containing protein 4 (NLR-C4) expression were enhanced after kidney IRI and decreased significantly by RMT3-23. Tim-3 not only promotes TLR-mediated nuclear factor kappa B (NF-kappaB) activation and cytokine and chemokine release, but also participates in NLR-C4 inflammasome activation. Taken together, our data confirm that Tim-3 signalling enhances injury after kidney IRI and demonstrated that Tim-3 is involved in regulating TLR-4/NF-kappaB signalling and NLR-C4 inflammasome activation, which provide evidence that Tim-3 signalling is critical for kidney IRI and may provide a new means to ameliorate kidney tissue immune responses in the clinics. PMID- 29570770 TI - Boosting phagocytosis and anti-inflammatory phenotype in microglia mediates neuroprotection by PPARgamma agonist MDG548 in Parkinson's disease models. AB - BACKGROUND AND PURPOSE: Microglial phenotype and phagocytic activity are deregulated in Parkinson's disease (PD). PPARgamma agonists are neuroprotective in experimental PD, but their role in regulating microglial phenotype and phagocytosis has been poorly investigated. We addressed it by using the PPARgamma agonist MDG548. EXPERIMENTAL APPROACH: Murine microglial cell line MMGT12 was stimulated with LPS and/or MDG548, and their effect on phagocytosis of fluorescent microspheres or necrotic neurons was investigated by flow cytometry. Cytokines and markers of microglia phenotype, such as mannose receptor C type 1; MRC1), Ym1 and CD68 were measured by elisa and fluorescent immunohistochemistry. Levels of Beclin-1, which plays a role in microglial phagocytosis, were measured by Western blotting. In the in vivo MPTP-probenecid (MPTPp) model of PD in mice, MDG548 was tested on motor impairment, nigral neurodegeneration, microglial activation and phenotype. KEY RESULTS: In LPS-stimulated microglia, MDG548 increased phagocytosis of both latex beads and necrotic cells, up-regulated the expression of MRC1, CD68 and to a lesser extent IL-10, while blocking the LPS induced increase of TNF-alpha and iNOS. MDG548 also induced Beclin-1. Chronic MPTPp treatment in mice down-regulated MRC1 and TGF-beta and up-regulated TNF alpha and IL-1beta immunoreactivity in activated CD11b-positive microglia, causing the death of nigral dopaminergic neurons. MDG548 arrested MPTPp-induced cell death, enhanced MRC1 and restored cytokine levels. CONCLUSIONS AND IMPLICATIONS: This study adds a novel mechanism for PPARgamma-mediated neuroprotection in PD and suggests that increasing phagocytic activity and anti inflammatory markers may represent an effective disease-modifying approach. PMID- 29570771 TI - The non-biphenyl-tetrazole angiotensin AT1 receptor antagonist eprosartan is a unique and robust inverse agonist of the active state of the AT1 receptor. AB - BACKGROUND AND PURPOSE: Conditions such as hypertension and renal allograft rejection are accompanied by chronic, agonist-independent, signalling by angiotensin II AT1 receptors. The current treatment paradigm for these diseases entails the preferred use of inverse agonist AT1 receptor blockers (ARBs). However, variability in the inverse agonist activities of common biphenyl tetrazole ARBs for the active state of AT1 receptors often leads to treatment failure. Therefore, characterization of robust inverse agonist ARBs for the active state of AT1 receptors is necessary. EXPERIMENTAL APPROACH: To identify the robust inverse agonist for active state of AT1 receptors and its molecular mechanism, we performed site-directed mutagenesis, competition binding assay, inositol phosphate production assay and molecular modelling for both ground-state wild-type AT1 receptors and active-state N111G mutant AT1 receptors. KEY RESULTS: Although candesartan and telmisartan exhibited weaker inverse agonist activity for N111G- compared with WT-AT1 receptors, only eprosartan exhibited robust inverse agonist activity for both N111G- and WT- AT1 receptors. Specific ligand receptor contacts for candesartan and telmisartan are altered in the active-state N111G- AT1 receptors compared with the ground-state WT-AT1 receptors, suggesting an explanation of their attenuated inverse agonist activity for the active state of AT1 receptors. In contrast, interactions between eprosartan and N111G-AT1 receptors were not significantly altered, and the inverse agonist activity of eprosartan was robust. CONCLUSIONS AND IMPLICATIONS: Eprosartan may be a better therapeutic option than other ARBs. Comparative studies investigating eprosartan and other ARBs for the treatment of diseases caused by chronic, agonist independent, AT1 receptor activation are warranted. PMID- 29570772 TI - Risk of basal cell carcinoma in a randomized clinical trial of aspirin and folic acid for the prevention of colorectal adenomas. AB - BACKGROUND: Aspirin may reduce the risk of several types of cancer. OBJECTIVES: To evaluate if folic acid is associated with risk of basal cell carcinoma (BCC). METHODS: BCC incidence was evaluated in a randomized, double-blind, placebo controlled clinical trial of aspirin (81 mg daily or 325 mg daily for ~3 years) and/or folic acid (1 mg daily for ~6 years) for the prevention of colorectal adenomas among 1121 participants with a previous adenoma. BCC was confirmed by blinded review of pathology reports. RESULTS: One hundred and four of 958 non Hispanic white participants were diagnosed with BCC over a median follow-up of 13.5 years. Cumulative incidence of BCC was 12% [95% confidence interval (CI) 7 17] for placebo, 16% (95% CI 11-21) for 81 mg aspirin daily and 15% (95% CI 10 20) for 325 mg aspirin daily [hazard ratio (HR) for any aspirin 1.45 (95% CI 0.93 2.26); HR for 81 mg daily 1.57 (95% CI 0.96-2.56); HR for 325 mg daily 1.33 (95% CI 0.80-2.20)]. BCC risk was higher with aspirin use in those without previous skin cancer but lower with aspirin use in those with previous skin cancer (Pinteraction = 0.02 for 81 mg aspirin daily; Pinteraction = 0.03 for 325 mg aspirin daily). Folic acid supplementation was unrelated to BCC incidence (HR 0.85; 95% CI 0.57-1.27). CONCLUSIONS: Neither aspirin nor folic acid treatment had a statistically significant effect on risk of BCC. Subgroup analysis suggested that chemopreventive effects of nonsteroidal anti-inflammatory drugs may be specific to those at high risk for BCC.

AB - Our nation's ongoing prescription opioid abuse crisis, amounting to over 78 billion dollars in health and social costs annually,1 is a critical priority for the US Food and Drug Administration (FDA). As a part of our mission to support the safe and effective use of prescription medicines, the FDA is taking a fresh look at potential scientific and regulatory actions we can take to address this crisis. PMID- 29570774 TI - Application of the Mesolens for subcellular resolution imaging of intact larval and whole adult Drosophila. AB - In a previous paper, we showed a new giant lens called the Mesolens and presented performance data and images from whole fixed and intact fluorescently-stained 12.5-day old mouse embryos. Here, we show that using the Mesolens we can image an entire Drosophila larva or adult fly in confocal epifluorescence and show subcellular detail in all tissues. By taking several hundreds of optical sections through the entire volume of the specimen, we show cells and nuclear details within the gut, brain, salivary glands and reproductive system that normally require dissection for study. Organs are imaged in situ in correct 3D arrangement. Imaginal discs are imaged in mature larvae and it proved possible to image pachytene chromosomes in cells within ovarian follicles in intact female flies. Methods for fixing, staining and clearing are given. PMID- 29570775 TI - Chemical Imaging of Cyanoacrylate-Fumed Fingerprints by Matrix-assisted Laser Desorption/Ionization Mass Spectrometry Imaging. AB - For new techniques to be incorporated into forensic science, they must be compatible with current practices. Here, cyanoacrylate fuming, a common development technique for latent fingerprints, is studied for its compatibility with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for chemical imaging of latent fingerprints. Half of a fingerprint was fumed while the other half was not; then, the changes in chemical composition and signal intensity were compared with MALDI-MS imaging. No evidence was found that fingerprint compounds are chemically altered by fuming or their signal intensities affected. The only exceptions were significant signal loss for quaternary ammonium compounds from hygiene products and moderate signal loss for tertiary amine compounds. This result is in striking contrast with the previous attempts by others, which is attributed to the difference in instrumentation. PMID- 29570777 TI - Fundamental Limits of Shaking a Baby. AB - Basic physics places limits on the mechanics involved in shaking a baby. Fundamental definitions and practical limitations are used to compare shaking with car crashes and low-level falls. First-order mathematical considerations applied to a 6-month-old infant determine an angular velocity limit for head rotation around 75 rad/s and maximum angular acceleration less than 1600 rad/s2 without impact. By comparison, results from a low-level fall of 0.76 m (30 inches) yield values of 83 rad/s and 13,000 rad/s2 in a practical worst-case scenario. PMID- 29570776 TI - The roles of resident, central and effector memory CD4 T-cells in protective immunity following infection or vaccination. AB - Immunological memory provides rapid protection to pathogens previously encountered through infection or vaccination. CD4 T-cells play a central role in all adaptive immune responses. Vaccines must, therefore, activate CD4 T-cells if they are to generate protective immunity. For many diseases, we do not have effective vaccines. These include human immunodeficiency virus (HIV), tuberculosis and malaria, which are responsible for many millions of deaths each year across the globe. CD4 T-cells play many different roles during the immune response coordinating the actions of many other cells. In order to harness the diverse protective effects of memory CD4 T-cells, we need to understand how memory CD4 T-cells are generated and how they protect the host. Here we review recent findings on the location of different subsets of memory CD4 T-cells that are found in peripheral tissues (tissue resident memory T-cells) and in the circulation (central and effector memory T-cells). We discuss the generation of these cells, and the evidence that demonstrates how they provide immune protection in animal and human challenge models. PMID- 29570778 TI - Secretory vesicles of immune cells contain only a limited number of interleukin 6 molecules. AB - Immune cells communicate by releasing large quantities of cytokines. Although the mechanisms of cytokine secretion are increasingly understood, quantitative knowledge of the number of cytokines per vesicle is still lacking. Here, we measured with quantitative microscopy the release rate of vesicles potentially carrying interleukin-6 (IL-6) in human dendritic cells. By comparing this to the total secreted IL-6, we estimate that secretory vesicles contain about 0.5-3 IL-6 molecules, but with a large spread among cells/donors. Moreover, IL-6 did not accumulate within most cells, indicating that synthesis and not trafficking is the bottleneck for IL-6 production. IL-6 accumulated in the Golgi apparatus only in ~ 10% of the cells. Understanding how immune cells produce cytokines is important for designing new immunomodulatory drugs. PMID- 29570779 TI - Surgical re-excision vs. observation for histologically dysplastic naevi: a systematic review of associated clinical outcomes. AB - BACKGROUND: The management of histologically dysplastic naevi (HDN) with re excision vs. observation remains controversial because of lack of evidence about associated melanoma outcomes. OBJECTIVES: To assess published data on the development of biopsy-site primary cutaneous melanoma among biopsy-proven HDN managed with either re-excision or observation. METHODS: A systematic review of all published data: a total of 5293 records were screened, 18 articles were assessed in full text and 12 studies met inclusion criteria. No controlled trials were identified. RESULTS: Most studies (11 of 12, 92%) were retrospective chart reviews, and one was both a cross-sectional and cohort study. Many studies (nine of 12, 75%) had no head-to-head comparison groups and either only reported HDN that were re-excised or observed. A total of 2673 (1535 observed vs. 1138 re excised) HDN of various grades were included. Follow-up varied between 2 weeks and 30 years. Nine studies reported that no melanomas developed. Eleven biopsy site melanomas developed across three of the studies, six among observed lesions (0.39%) and five among re-excised lesions (0.44%). CONCLUSIONS: Based upon the available evidence the rates of biopsy-site primary melanoma were similarly low among observed lesions and re-excised lesions. This suggests that HDNs can be observed with minimal adverse melanoma-associated outcomes. However, all included articles were of low quality and further prospective trials could better guide clinical decision making. PMID- 29570781 TI - The President's Commission on Combating Drug Addiction and the Opioid Crisis: Origins and Recommendations. AB - The United States has the ignominious distinction of leading the world in opioid prescribing,1 and in opioid-related overdose deaths. The Centers for Disease Control (CDC) estimates that over 40,000 people died of an opioid-related overdose, with fentanyl-related deaths exceeding those of heroin or prescription opioids.2 Opioid overdoses are now the leading cause of unintentional deaths in the US and of declining lifespan expectancies.3 With a worsening crisis, agencies of the US government and others produced an array of reports on the opioid crisis. Yet the death rate escalated further from 2010 to the present. PMID- 29570780 TI - Effects of ischemic post-conditioning on neuronal VEGF regulation and microglial polarization in a rat model of focal cerebral ischemia. AB - Ischemic postconditioning is increasingly being investigated as a therapeutic approach for cerebral ischemia. However, the majority of studies are focused on the acute protection of neurons per se. Whether and how postconditioning affects multiple cells in the recovering neurovascular unit remains to be fully elucidated. Here, we asked whether postconditioning may modulate help-me signaling between injured neurons and reactive microglia. Rats were subjected to 100 min of focal cerebral ischemia, then randomized into a control versus postconditioning group. After 3 days of reperfusion, infarct volumes were significantly reduced in animals treated with postconditioning, along with better neurologic outcomes. Immunostaining revealed that ischemic postconditioning increased expression of vascular endothelial growth factor (VEGF) in neurons within peri-infarct regions. Correspondingly, we confirmed that VEGFR2 was expressed on Iba1-positive microglia/macrophages, and confocal microscopy showed that in postconditioned rats, these cells were polarized to a ramified morphology with higher expression of M2-like markers. Treating rats with a VEGF receptor 2 kinase inhibitor negated these effects of postconditioning on microglia/macrophage polarization. In vitro, postconditoning after oxygen-glucose deprivation up-regulated VEGF release in primary neuron cultures, and adding VEGF to microglial cultures partly shifted their M2-like markers. Altogether, our findings support the idea that after postconditioning, injured neurons may release VEGF as a 'help-me' signal that promotes microglia/macrophage polarization into potentially beneficial phenotypes. PMID- 29570782 TI - Childhood neurodevelopmental disorders and risk of coercive sexual victimization in childhood and adolescence - a population-based prospective twin study. AB - BACKGROUND: Autism spectrum disorder (ASD), Attention-deficit/Hyperactivity disorder (ADHD), and other related neurodevelopmental disorders (NDDs) have, in some previous studies, been shown to increase the risk of being sexually victimized. However, no studies have examined whether the association is driven by a general NDD phenotype versus specific diagnoses, nor the etiology of the association. METHOD: Using a genetically informative, prospective design, we examined the association between ASD and ADHD in childhood and coercive sexual victimization up to age 18. A total of 4,500 children participating in the Child and Adolescent Twin Study in Sweden (CATSS) were rated by their parents on NDDs at age 9 or 12 years, and self-reported at age 18 on lifetime experiences of coercive sexual touching and/or coercive sex. First, we regressed sexual victimization on the NDDs. Second, we regressed sexual victimization on general and specific NDD symptoms identified via a bifactor model. Third, we decomposed the observed associations into genetic and environmental parts. RESULTS: In females, ASD was associated with an almost threefolded increased risk of coercive sexual victimization, and ADHD with a doubled risk. In males, the risk associated with ASD and ADHD was of the same magnitude but not significant. When controlling for overall NDD symptom load ASD or ADHD, no longer uniquely predicted coercive sexual victimization. The association between the NDD general factor and coercive sexual victimization was due to shared genetics. CONCLUSIONS: General NDD symptom load, rather than specific ASD or ADHD symptoms, seems to be a moderate vulnerability factor for coercive sexual victimization. We speculate that an evocative gene-environment correlation might account for this observation, such that sexual perpetrators actively target NDD individuals. PMID- 29570783 TI - Defining the role of NK cells during dengue virus infection. AB - In recent years, our understanding of the complex number of signals that need to be integrated between a diverse number of receptors present on natural killer (NK) cells and ligands present on target cells has improved. Here, we review the progress made in identifying interactions between dengue viral peptides presented on HLA Class 1 molecules with inhibitory and activating killer-like immunoglobulin receptors on NK cells, direct interactions of viral proteins with NK cell receptors, the involvement of dengue virus-specific antibodies in mediating antibody-dependent cell-mediated cytotoxicity and the role of soluble factors in modulating NK cell responses. We discuss findings of NK cell activation early after natural dengue infection, and point to the role that NK cells may play in regulating both innate and adaptive immune responses, in the context of our new appreciation of interactions of dengue virus with specific NK cell receptors. With a number of flavivirus vaccine candidates in clinical trials, how NK cells respond to attenuated dengue virus and subunit protein vaccine candidates and shape adaptive immunity will need to be considered. PMID- 29570784 TI - Origin context of trait data matters for predictions of community performance in a grassland biodiversity experiment. AB - Plant functional traits may explain the positive relationship between species richness and ecosystem functioning, but species-level trait variation in response to growth conditions is often ignored in trait-based predictions of community performance. In a large grassland biodiversity experiment (Jena Experiment), we measured traits on plants grown as solitary individuals, in monocultures or in mixtures. We calculated two measures of community-level trait composition, i.e., community-weighted mean traits (CWM) and trait diversity (Rao's quadratic entropy; FD) based on different contexts in which traits were measured (trait origins). CWM and FD values of the different measurement origins were then compared regarding their power to predict community biomass production and biodiversity effects quantified with the additive partitioning method. Irrespective of trait origin, models combining CWM and FD values as predictors best explained community biomass and biodiversity effects. CWM values based on monoculture, mixture-mean or community-specific trait data were similarly powerful predictors, but predictions became worse when trait values originated from solitary-grown individuals. FD values based on monoculture traits were the best predictors of community biomass and net biodiversity effects, while FD values based on community-specific traits were the best predictors for complementarity and selection effects. Traits chosen as best CWM predictors were not strongly affected by trait origin but traits chosen as best FD predictors varied strongly dependent on trait origin and altered the predictability of community performance. We conclude that by adjusting their functional traits to species richness and even specific community compositions, plants can change community-level trait compositions, thereby also changing community biomass production and biodiversity effects. Incorporation of these plastic trait adjustments of plants in trait-based ecology can improve its predictive power in explaining biodiversity-ecosystem functioning relationships. PMID- 29570792 TI - Genomics studies on musical aptitude, music perception, and practice. AB - When searching for genetic markers inherited together with musical aptitude, genes affecting inner ear development and brain function were identified. The alpha-synuclein gene (SNCA), located in the most significant linkage region of musical aptitude, was overexpressed when listening and performing music. The GATA binding protein 2 gene (GATA2) was located in the best associated region of musical aptitude and regulates SNCA in dopaminergic neurons, thus linking DNA- and RNA-based studies of music-related traits together. In addition to SNCA, several other genes were linked to dopamine metabolism. Mutations in SNCA predispose to Lewy-body dementia and cause Parkinson disease in humans and affect song production in songbirds. Several other birdsong genes were found in transcriptome analysis, suggesting a common evolutionary background of sound perception and production in humans and songbirds. Regions of positive selection with musical aptitude contained genes affecting auditory perception, cognitive performance, memory, human language development, and song perception and production of songbirds. The data support the role of dopaminergic pathway and their link to the reward mechanism as a molecular determinant in positive selection of music. Integration of gene-level data from the literature across multiple species prioritized activity-dependent immediate early genes as candidate genes in musical aptitude and listening to and performing music.

AB - Technological advances have led to the identification of biomarkers and development of novel target-based therapies. While some novel therapies have improved patient outcomes, the prevalence and diversity of biomarkers and targets in patient populations, especially patients with cancer, has created a challenge for the design and performance of clinical trials. To address this challenge we propose that prospective cohort surveillance of patients may be a solution to promote clinical trial matching for patients in need. PMID- 29570793 TI - Relationship of premenstrual and menstrual symptoms to alexithymia among nursing students. AB - PURPOSE: The aim of this study is to determine the relationship of premenstrual and menstrual symptoms to alexithymia among nursing students. DESIGN AND METHODS: This descriptive study was conducted with 284 undergraduate nursing students. Data were collected using Premenstrual Syndrome Scale (PMSS), Menstrual Symptom Scale (MSQ), and Toronto Alexithymia Scale-20 (TAS-20). FINDINGS: The PMSS, MSQ, and TAS-20 mean scores were 103.56 +/- 35.08, 2.92 +/- 0.8, and 45.22 +/- 9.17, respectively. There was statistically significant positive correlation between TAS-20 and PMSS and MSQ mean scores (p < .05). PRACTICAL IMPLICATIONS: Women should be evaluated for alexithymia to prevent the adverse effects of premenstrual and menstrual symptoms.

AB - Bone marrow fibrosis is the continuous replacement of blood-forming cells in the bone marrow with excessive scar tissue, leading to failure of the body to produce blood cells and ultimately to death. Myofibroblasts are fibrosis-driving cells and are well characterized in solid organ fibrosis, but their role and cellular origin in bone marrow fibrosis have remained obscure. Recent work has demonstrated that Gli1+ and leptin receptor+ mesenchymal stromal cells are progenitors of fibrosis-causing myofibroblasts in the bone marrow. Genetic ablation or pharmacological inhibition of Gli1+ mesenchymal stromal cells ameliorated fibrosis in mouse models of myelofibrosis. Conditional deletion of the platelet-derived growth factor (PDGF) receptor-alpha (PDGFRA) gene (Pdgfra) and inhibition of PDGFRA by imatinib in leptin receptor+ stromal cells suppressed their expansion and ameliorated bone marrow fibrosis. Understanding the cellular and molecular mechanisms in the haematopoietic stem cell niche that govern the mesenchymal stromal cell-to-myofibroblast transition and myofibroblast expansion will be critical to understand the pathogenesis of bone marrow fibrosis in both malignant and non-malignant conditions, and will guide the development of novel therapeutics. In this review, we summarize recent discoveries of mesenchymal stromal cells as part of the haematopoietic niche and as myofibroblast precursors, and discuss potential therapeutic strategies in the specific targeting of fibrotic transformation in bone marrow fibrosis.

PMID- 29570795 TI - Cortical progenitor biology: key features mediating proliferation versus differentiation. AB - The cerebral cortex is a highly organized structure whose development depends on diverse progenitor cell types, namely apical radial glia, intermediate progenitors, and basal radial glia cells, which are responsible for the production of the correct neuronal output. In recent years, these progenitor cell types have been deeply studied, particularly basal radial glia and their role in cortical expansion and gyrification. We review here a broad series of factors that regulate progenitor behavior and daughter cell fate. We first describe the different neuronal progenitor types, emphasizing the differences between lissencephalic and gyrencephalic species. We then review key factors shown to influence progenitor proliferation versus differentiation, discussing their roles in progenitor dynamics, neuronal production, and potentially brain size and complexity. Although spindle orientation has been considered a critical factor for mode of division and daughter cell output, we discuss other features that are emerging as crucial for these processes such as organelle and cell cycle dynamics. Additionally, we highlight the importance of adhesion molecules and the polarity complex for correct cortical development. Finally, we briefly discuss studies assessing progenitor multipotency and its possible contribution to the production of specific neuronal populations. This review hence summarizes recent aspects of cortical progenitor cell biology, and pinpoints emerging features critical for their behavior. PMID- 29570796 TI - Do beliefs about depression etiologies influence the type and severity of depression stigma? The case of Arab adolescents. AB - PURPOSE: Research has documented that holding certain etiological beliefs about depression can determine the level of stigma experienced by individuals with depression. To date, no studies have yet examined this relationship among adolescents. Using a sample of Arab adolescents, the purpose of this study was to describe adolescents' beliefs about the etiology of depression, and examine whether these beliefs influence the type and severity of depression stigma. METHODS: A nationwide school survey was conducted in a representative sample of Jordanian public and private schools located in Jordan, a Middle-Eastern Arab country. A total of 2,349 adolescents aged 12-17 (59% female) completed and returned an anonymous survey that included measures on adolescents' sociodemographic and health characteristics, depression symptoms, depression stigma, and depression etiological beliefs. An exploratory factor analysis with principal components analysis (PCA) was used to examine the factor structure of the Depression Etiological Beliefs Scale. The stability of the PCA findings was tested using a cross-validation method. Regression analyses were performed to examine whether depression etiological beliefs, depression severity, or their interaction are associated with depression stigma. RESULTS: Adolescents endorsed multiple etiological beliefs about depression. The beliefs in which likely or very likely was most often reported were stressful events in one's life (72%), social factors (65%), and one's weak will (56%). On the other hand, the least reported beliefs were genetic or inherited problems (24%), chemical imbalance (30%), and punishment for wrong doings (35%). The interaction between adolescents' depression severity and depression beliefs significantly predicted personal stigma. Adolescent sex, age, and region of residence significantly affected the relationship between depression beliefs and stigma. CONCLUSIONS: Nurses need to consider the beliefs and attitudes their patients have around depression, as these can influence symptom severity, comprehensive treatment plans, and adherence to provider recommendations. This study provides a better understanding of how depression beliefs affect Jordanian adolescents' attitudes toward depression, which can guide intervention programs to increase awareness about depression and promote treatment utilization. PMID- 29570797 TI - Fetal hydrometrocolpos and congenital imperforate hymen: Prenatal and postnatal imaging features. AB - Congenital imperforate hymen is probably the most common obstructive anomaly of the female reproductive tract. The accumulation of fluid in the genital tract leads to a distended uterus and vagina, causing hydrometrocolpos. Prenatal diagnosis of fetal hydrometrocolpos is uncommon, with only 22 cases reported in the literature and only a few cases of prenatal imaging of this condition available to date. The main ultrasound finding is a fetal pelvic mass posterior to the bladder and anterior to the rectum. We present the case of a 37-week female fetus with a fetal pelvic mass detected in a routine obstetric ultrasound examination, and the correlation between the prenatal and postnatal findings.

AB - This study evaluated the effects of a ketogenic diet (KD) based on extra virgin coconut oil (Cocos nucifera L., VCO), on the treatment of epileptic rats. Two sets of experiments were conducted. First, male Wistar rats underwent induction of status epilepticus (SE) with the administration of pilocarpine intraperitoneally 21 animals reached spontaneous recurrent seizures (SRS) and were randomly allocated to the dietary regimens and video-monitored for 19 days. In the second experiment, 24 animals were randomized immediately after the induction of SE and followed for 67 days. Diets were as follows: Control (AIN 93G; 7% lipid), KetoTAGsoya (KD based on soybean oil; 69.79% lipid), and KetoTAGcoco (KD based on VCO; 69.79% lipid). There were no differences in the latency to the first crisis, total frequency, and duration of the SRS between groups in 2 experiments. The data suggest no effects of KD, with or without VCO, in rats with pilocarpine-induced epilepsy. PMID- 29570801 TI - Predictive factors in 995 stapes surgeries for primary otosclerosis. AB - OBJECTIVES/HYPOTHESIS: This study sought to identify the predictors of outcome in patients with otosclerosis undergoing primary stapes surgery. STUDY DESIGN: Retrospective analysis of medical records. METHODS: A total of 995 patients with otosclerosis who underwent primary stapes surgery by a single surgeon between January 2006 and December 2016 were included. Logistic regression analysis was performed to examine factors affecting postoperative hearing thresholds at individual frequencies. A postoperative air-bone gap (ABG) closure <= 10 dB in the stapes surgery was considered as excellent outcome. RESULTS: Stapedotomies and stapedectomies were conducted in 823 and 172 ears, respectively. The surgeries had an overall success rate of 93.6%. Univariate analysis showed a significantly higher success rate in patients with larger prostheses (diameter = 0.6 mm). According to the results of multivariate logistic regression analysis, preoperative ABG (B coefficient = -0.10), bilaterality (odds ratio [OR] = 2.09), right ear involvement (OR = 2.00), female gender (OR = 1.81), and nonobliterative footplate (OR = 3.69) were significant prognostic factors predicting excellent outcome. CONCLUSIONS: Our findings indicated that the functional results were generally good. Based on logistic regression analysis, preoperative ABG and nonobliterative footplate were the most important predictors of hearing outcome after stapes surgery for otosclerosis. The success of the surgery did not depend on the procedure types (stapedotomy vs. stapedectomy) or the diameter of the prosthesis (0.4 mm vs. 0.6 mm). LEVEL OF EVIDENCE: 4.

AB - BACKGROUND: The aims of this study were to evaluate the microbiological trends in severe odontogenic infections requiring hospital admission in the South Australian Oral and Maxillofacial Surgery Unit. Rates of antibiotic resistance to empirical antibiotic regimens were determined to quantify the clinical implications of antibiotic-resistant odontogenic infections. METHODS: A retrospective case audit was performed on all odontogenic infections admitted to the Royal Adelaide Hospital over a 9-year period. Data was collected regarding demographics, microbiological culture and sensitivity results, and clinical outcome variables. RESULTS: Of a total of 672 patients, microbiology data was available for 447 cases. Penicillin-resistant organisms were identified in 10.8% of patients, who required a significantly longer length of hospital admission (mean, 9.93 days) and higher rates of non-response to initial surgical therapy (40%). CONCLUSIONS: There were moderate rates of antibiotic-resistant odontogenic infections within the South Australian population. Patients within this subgroup demonstrate markedly poorer clinical outcomes. Effective treatment of odontogenic infections involves early operative intervention, with adjunctive use of appropriate antibiotic therapy that involves close monitoring of response to removal of the cause and use of first-line antibiotic agents. Cases that fail to respond require urgent specialist review in order to reduce morbidity and mortality outcomes. PMID- 29570800 TI - DNA methylation of microRNA-coding genes in non-small-cell lung cancer patients. AB - Deregulated DNA methylation leading to transcriptional inactivation of certain genes occurs frequently in non-small-cell lung cancers (NSCLCs). As well as protein-coding genes, microRNA (miRNA)-coding genes may be targets for methylation in NSCLCs; however, the number of known methylated miRNA genes is still small. Thus, we investigated methylation of miRNA genes in primary tumour (TU) samples and corresponding non-malignant lung tissue (NL) samples of 50 NSCLC patients by using methylated DNA immunoprecipitation followed by custom-designed tiling microarray analyses (MeDIP-chip), and 252 differentially methylated probes between TU samples and NL samples were identified. These probes were annotated, which resulted in the identification of 34 miRNA genes with increased methylation in TU samples. Some of these miRNA genes were already known to be methylated in NSCLCs (e.g. those encoding miR-9-3 and miR-124), but methylation of the vast majority of them was previously unknown. We selected six miRNA genes (those encoding miR-10b, miR-1179, miR-137, miR-572, miR-3150b, and miR-129-2) for gene specific methylation analyses in TU samples and corresponding NL samples of 104 NSCLC patients, and observed a statistically significant increase in methylation of these genes in TU samples (p < 0.0001). In silico target prediction of the six miRNAs identified several oncogenic/cell proliferation-promoting factors (e.g. CCNE1 as an miR-1179 target). To investigate whether miR-1179 indeed targets CCNE1, we transfected miR-1179 gene mimics into CCNE1-expressing NSCLC cells, and observed downregulated CCNE1 mRNA expression in these cells as compared with control cells. Similar effects on cyclin E1 expression were seen in western blot analyses. In addition, we found a statistically significant reduction in the growth of NSCLC cells transfected with miR-1179 mimics as compared with control cells. In conclusion, we identified many methylated miRNA genes in NSCLC patients, and found that the miR-1179 gene is a potential tumour cell growth suppressor in NSCLCs. Overall, our findings emphasize the impact of miRNA gene methylation on the pathogenesis of NSCLCs. (c) 2018 The Authors.

PMID- 29570803 TI - Facial hyperalgesia due to direct action of endothelin-1 in the trigeminal ganglion of mice. AB - OBJECTIVE: This study assessed the ability of endothelin-1 (ET-1) to evoke heat hyperalgesia when injected directly into the trigeminal ganglia (TG) of mice and determined the receptors implicated in this effect. The effects of TG ETA and ETB receptor blockade on alleviation of heat hyperalgesia in a model of trigeminal neuropathic pain induced by infraorbital nerve constriction (CION) were also examined. METHODS: Naive mice received an intraganglionar (i.g.) injection of ET 1 (0.3-3 pmol) or the selective ETB R agonist sarafotoxin S6c (3-30 pmol), and response latencies to ipsilateral heat stimulation were assessed before the treatment and at 1-h intervals up to 5 h after the treatment. Heat hyperalgesia induced by i.g. ET-1 or CION was assessed after i.g. injections of ETA R and ETB R antagonists (BQ-123 and BQ-788, respectively, each at 0.5 nmol). KEY FINDINGS: Intraganglionar ET-1 or sarafotoxin S6c injection induced heat hyperalgesia lasting 4 and 2 h, respectively. Heat hyperalgesia induced by ET-1 was attenuated by i.g. BQ-123 or BQ-788. On day 5 after CION, i.g. BQ-788 injection produced a more robust antihyperalgesic effect compared with BQ-123. CONCLUSIONS: ET-1 injection into the TG promotes ETA R/ETB R-mediated facial heat hyperalgesia, and both receptors are clearly implicated in CION-induced hyperalgesia in the murine TG system. PMID- 29570804 TI - Effects of an empowerment program for community-dwelling people with mental illness in South Korea. AB - PURPOSE: This study aimed to examine the effects of an empowerment program on empowerment, quality of life, and recognition of human rights of people with mental illness residing in a community in South Korea. DESIGN AND METHODS: A repeated-measures design (before, immediately after, and 4 weeks after the intervention) with a control group was used. The experimental group received an eight-session empowerment program over 8 weeks. FINDINGS: The empowerment program significantly increased empowerment and quality of life, but not recognition of human rights. PRACTICE IMPLICATIONS: Nursing interventions should be developed to enhance the recognition of human rights for people with mental illness. PMID- 29570805 TI - Algorithm Analysis of the DSM-5 Alcohol Withdrawal Symptom. AB - BACKGROUND: Alcohol withdrawal (AW) is an important clinical and diagnostic feature of alcohol dependence. AW has been found to predict a worsened course of illness in clinical samples, but in some community studies, AW endorsement rates are strikingly high, suggesting false-positive symptom assignments. Little research has examined the validity of the DSM-5 algorithm for AW, which requires either the presence of at least 2 of 8 subcriteria (i.e., autonomic hyperactivity, tremulousness, insomnia, nausea, hallucinations, psychomotor agitation, anxiety, and grand mal seizures), or, the use of alcohol to avoid or relieve these symptoms. METHODS: We used item and algorithm analyses of data from waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (current drinkers, n = 26,946 at wave 1) to study the validity of DSM 5 AW as operationalized by the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV (AUDADIS-IV). RESULTS: A substantial proportion of individuals given the AW symptom reported only modest to moderate levels of alcohol use and alcohol problems. Alternative AW algorithms were superior to DSM 5 in terms of levels of alcohol use and alcohol problem severity among those with AW, group difference effect sizes, and predictive validity at a 3-year follow-up. The superior alternative algorithms included those that excluded the nausea subcriterion; required withdrawal-related distress or impairment; increased the AW subcriteria threshold from 2 to 3 items; and required tremulousness for AW symptom assignment. CONCLUSIONS: The results indicate that the DSM-5 definition of AW, as assessed by the AUDADIS-IV, has low specificity. This shortcoming can be addressed by making the algorithm for symptom assignment more stringent. PMID- 29570806 TI - Preparation of citrus pectin gels by power ultrasound and its application as an edible coating in strawberries. AB - BACKGROUND: Pectin is heteropolysaccharide found in cell walls originating mainly from by-products, as well as citrus peels, apple and sugar beet pulp, and presenting biological and techno-functional properties. In the present study, a general and structural characterisation of industrial citrus pectins was performed together with a study of impact of power ultrasound (US) on their rheological properties, with the aim of using them as edible coatings for fresh strawberries. RESULTS: The results obtained indicated that pure pectin showed a methylesterification degree greater than 50% and galacturonic acid content > 65%, supporting its consideration as additive E-440; such conditions were not achieved in pectin with sugar addition. Furthermore, in the rheological study, pectin gels showed a non-Newtonian flow and pseudoplastic behaviour and presented different viscosity ranges depending on the preparation methods, including power US. Gels were used as edible coatings for fresh strawberries aiming to improve their quality during storage over a period of 5 days, controlling quality characteristics such as humidity loss, acidity and colour parameters (L*, a*, b*, C, h degrees , DeltaE). CONCLUSION: The results obtained demonstrate that US treatments give rise to pectin gels that can improve the quality of strawberries over their lifetime. (c) 2018 Society of Chemical Industry.

AB - The Glasgow Coma Scale (GCS), which classifies patients into mild, moderate or severe traumatic brain injury (TBI), is a system used to prioritize treatment and prognosticate the severity of head injury. In this study, sera of patients with various stages of TBI, as well as control subjects, were analyzed to screen for proteins that may be used to complement the GCS system. By subjecting pooled serum samples to iTRAQ analysis for quantitative comparison of protein abundance, and attesting their altered levels using ELISA, we have detected increased levels of serum amyloid A, C-reactive protein, leucine-rich alpha-2-glycoprotein, lipopolysaccharide-binding protein, fibronectin, vitronectin and alpha-1 antichymotrypsin in patients across all strata of TBI relative to the controls. However, kininogen was decreased only in moderate and severe TBI, whereas apolipoprotein E and zinc-alpha-2-glycoprotein were only increased in severe TBI. Hence, we propose a panel of serum biomarkers, which if analyzed within 24 h of the injury, can be used to diagnose patients with TBI into mild, moderate or severe stratification objectively, thus complementing the traditional GCS. PMID- 29570808 TI - An independent validation study of loci associated with nematode resistance in sheep. AB - Gastrointestinal nematode infection is a constraint on sheep production worldwide. Selective breeding programmes to enhance resistance to nematode infection are currently being implemented in a number of countries. Identification of loci associated with resistance to infection or causative mutations for resistance would enable more effective selection. Loci associated with indicator traits for nematode resistance has been identified in previous studies. In this study, Scottish Blackface, Texel and Suffolk lambs were used to validate the effects at eight genomic regions previously associated with nematode resistance (OAR3, 4, 5, 7, 12, 13, 14, 21). No SNP was significantly associated with nematode resistance at the region-wide level but seven SNPs in three of the regions (OAR4, 12, 14) were nominally associated with trichostrongyle egg count in this study and six of these were also significant when fitted as single SNP effects. Nematodirus egg count was nominally associated with SNPs on OAR3, 4, 7 and 12. PMID- 29570809 TI - Impact of joint statistical dual-energy CT reconstruction of proton stopping power images: Comparison to image- and sinogram-domain material decomposition approaches. AB - PURPOSE: The purpose of this study was to assess the performance of a novel dual energy CT (DECT) approach for proton stopping power ratio (SPR) mapping that integrates image reconstruction and material characterization using a joint statistical image reconstruction (JSIR) method based on a linear basis vector model (BVM). A systematic comparison between the JSIR-BVM method and previously described DECT image- and sinogram-domain decomposition approaches is also carried out on synthetic data. METHODS: The JSIR-BVM method was implemented to estimate the electron densities and mean excitation energies (I-values) required by the Bethe equation for SPR mapping. In addition, image- and sinogram-domain DECT methods based on three available SPR models including BVM were implemented for comparison. The intrinsic SPR modeling accuracy of the three models was first validated. Synthetic DECT transmission sinograms of two 330 mm diameter phantoms each containing 17 soft and bony tissues (for a total of 34) of known composition were then generated with spectra of 90 and 140 kVp. The estimation accuracy of the reconstructed SPR images were evaluated for the seven investigated methods. The impact of phantom size and insert location on SPR estimation accuracy was also investigated. RESULTS: All three selected DECT-SPR models predict the SPR of all tissue types with less than 0.2% RMS errors under idealized conditions with no reconstruction uncertainties. When applied to synthetic sinograms, the JSIR BVM method achieves the best performance with mean and RMS-average errors of less than 0.05% and 0.3%, respectively, for all noise levels, while the image- and sinogram-domain decomposition methods show increasing mean and RMS-average errors with increasing noise level. The JSIR-BVM method also reduces statistical SPR variation by sixfold compared to other methods. A 25% phantom diameter change causes up to 4% SPR differences for the image-domain decomposition approach, while the JSIR-BVM method and sinogram-domain decomposition methods are insensitive to size change. CONCLUSION: Among all the investigated methods, the JSIR-BVM method achieves the best performance for SPR estimation in our simulation phantom study. This novel method is robust with respect to sinogram noise and residual beam-hardening effects, yielding SPR estimation errors comparable to intrinsic BVM modeling error. In contrast, the achievable SPR estimation accuracy of the image- and sinogram-domain decomposition methods is dominated by the CT image intensity uncertainties introduced by the reconstruction and decomposition processes. PMID- 29570810 TI - Laryngeal mask airway and transient hypercapnic hyperpnea for video-endoscopic assessment of unilateral laryngeal paralysis in dogs. AB - OBJECTIVE: To evaluate the ability to assess laryngeal function and to diagnose unilateral laryngeal paralysis (uLP) via airway endoscopy and carbon dioxide (CO2 ) stimulation. STUDY DESIGN: Experimental study. ANIMALS: Six healthy, adult beagles. METHODS: Dogs were anesthetized with sevoflurane and dexmedetomidine. Laryngeal activity was observed via endoscopy placed through a laryngeal mask airway (LMA). The absolute and normalized glottic gap areas (AGGA and NGGA, respectively) and the glottic length (GL) were measured at inspiration and before and after surgically induced uLP. Measurements were obtained at eupnea and during hypercapnic hyperpnea produced by the administration of CO2 . Values for each hemilarynx were also measured. Video recordings were observed by 2 surgeons who scored function as normal or uLP. RESULTS: The AGGA and NGGA increased similarly during CO2 administration in intact dogs and in dogs with uLP; the GL increased in dogs with uLP but not in intact dogs. The AGGA and NGGA of the intact hemilarynx increased more than those of the affected hemilarynx in dogs with uLP. uLP was correctly identified more frequently by observers at hypercapnic hyperpnea than during eupnea. CONCLUSION: The increase in AGGA and NGGA at peak inspiration during CO2 administration was not limited by uLP, but asymmetry in hemilarynx AGGA and NGGA was observed in dogs with uLP. CO2 administration facilitated the identification of uLP. CLINICAL SIGNIFICANCE: Laryngeal endoscopy through an LMA coupled with administration of CO2 in anesthetized dogs facilitates the observation of arytenoid function and may improve the diagnosis of naturally occurring mild laryngeal paralysis. PMID- 29570811 TI - Detection on pharyngeal wall floppiness in patients with nonstructural factor induced obstructive sleep apnea-hypopnea syndrome: Difference in position detection. AB - OBJECTIVES/HYPOTHESIS: To evaluate changes in pharyngeal wall floppiness (PWF) between patients with obstructive sleep apnea-hypopnea syndrome induced by non upper-airway structural factors and normal subjects, as well as the clinical significance using acoustic pharyngealmetry technology. STUDY DESIGN: Cohort study. METHODS: The obstructive sleep apnea (OSA) group (n = 102) and the normal control group (n = 50) were identified using the Eccovision Acoustic Pharyngometer measuring instrument. The volume of the pharyngeal cavity in the sitting and supine positions during expiration and inspiration was recorded, respectively, and the PWF index in the sitting and supine positions was calculated for further statistical analysis. RESULTS: PWF in the sitting (P < .001) and supine positions (P < .001) in the OSA group was notably higher than that in the control group. PWF in the supine position in both the OSA group and control group was remarkably higher than that in the sitting position (P < .001, P = .025, respectively). The difference in PWF between the supine and sitting positions (DeltaPWF) (PWF_supine-PWF_sit) was distinctly higher than in control group (P < .01). PWF was positively correlated with age (P < .001) but not with body mass index (P > .05). CONCLUSIONS: PWF, quantified as elevated PWF, is an important nonstructural factor for the pathogenesis of OSA patients. PWF in the supine position can more accurately reflect airway collapsibility in OSA patients. Our pilot study of a novel observation may help us in the choice of proper surgical candidates for OSA procedures. LEVEL OF EVIDENCE: 3b Laryngoscope, 128:2200-2205, 2018.

PMID- 29570813 TI - In Vivo Biofilm Formation, Gram-Negative Infections and TAS2R38 Polymorphisms in CRSw NP Patients. AB - OBJECTIVES: Among the predisposing factors implicated in the immune response to airway bacterial infections, genetic variations of the bitter taste receptor TAS2R38, which is expressed in the cilia of the human sinonasal epithelial cells, seem to be associated with susceptibility to chronic rhinosinusitis (CRS) and in vitro biofilm formation. Polymorphisms in TAS2R38 generate two common haplotypes: the nonfunctional AVI (Alanine, Valine, Isoleucine) and the functional PAV (Proline, Alanine, Valine) alleles, with the latter protecting against gram negative sinonasal infections. The aim of this study is to investigate for the first time the relevance of TAS2R38 genetic variants in the susceptibility to bacterial infections associated with in vivo biofilm formation in chronic rhinosinusitis with nasal polyps (CRSwNP) patients. STUDY DESIGN: A prospective study on 100 adult patients undergoing functional endoscopic sinus surgery (FESS) for CRSwNP. METHODS: Propylthiouracile (PROP) testing and TAS2R38 genotyping were applied to characterize patients for receptor functionality. Sinonasal mucosa samples were processed for microbiological examination and biofilm detection. RESULTS: The nonfunctional genotype is more frequent among CRS patients than in the general population (25% vs. 18.4%, P = 0.034). Airway gram-negative infections are primarily associated with the AVI haplotype (88.9% vs. 11.1% PAV/PAV-functional genotype, P = 0.023). Biofilm formation is prevalent in CRS patients with the AVI nontaster phenotype (62.5% vs. 33.3% PAV taster or supertaster phenotype, P = 0.05). CONCLUSION: Our findings confirm an inverse correlation between TAS2R38 functionality and gram-negative infections in Italian patients with CRSwNP. In addition, for the first time we demonstrated a relationship between in vivo microbial biofilm and TAS2R38 receptor variants. LEVEL OF EVIDENCE: 2b. Laryngoscope, 128:E339-E345, 2018. PMID- 29570814 TI - Using stable distributions to characterize proton pencil beams. AB - PURPOSE: To introduce and evaluate the use of stable distributions as a methodology to quantify the behavior of proton pencil beams in a medium. METHODS: The proton pencil beams of a clinically commissioned proton treatment facility are replicated in a Monte Carlo simulation system (FLUKA). For each available energy, the beam deposition in water medium is characterized by the dose deposition. Using a stable distribution methodology, each beam with a nominal energy E is characterized by the lateral spread at depth z: S(z; alpha, gamma, E) and a total energy deposition ID (z, E). The parameter alpha describes the tailedness of the distributions, while gamma is used to scale the size of the function. The beams can then be described completely by a function of the variation of the parameters with depth. RESULTS: Quantitatively, the fit of the stable distributions, compared to those implemented in some standard treatment planning systems, are equivalent for all but the highest energies (i.e., 230 MeV/u). The decrease in goodness of fit makes this methodology comparable to a double Gaussian approach. The introduction of restricted linear combinations of stable distributions also resolves that particular case. More importantly, the meta-parameterization (i.e., the description of the dose deposition by only providing the fitted parameters) allows for interpolation of nonmeasured data. In the case of the clinical commissioning data used in this paper, it was possible to only commission one out of five nominal energies to obtain a viable dataset, valid for all energies. An additional parameter beta allows to describe asymmetric beam profiles as well. CONCLUSIONS: Stable distributions are intrinsically suited to describe proton pencil beams in a medium and provide a tool to quantify the propagation of proton beams in a medium. PMID- 29570815 TI - Identifying auditory cortex encoding abnormalities in schizophrenia: The utility of low-frequency versus 40 Hz steady-state measures. AB - Magnetoencephalography (MEG) and EEG have identified poststimulus low frequency and 40 Hz steady-state auditory encoding abnormalities in schizophrenia (SZ). Negative findings have also appeared. To identify factors contributing to these inconsistencies, healthy control (HC) and SZ group differences were examined in MEG and EEG source space and EEG sensor space, with better group differentiation hypothesized for source than sensor measures given greater predictive utility for source measures. Fifty-five HC and 41 chronic SZ were presented 500 Hz sinusoidal stimuli modulated at 40 Hz during simultaneous whole-head MEG and EEG. MEG and EEG source models using left and right superior temporal gyrus (STG) dipoles estimated trial-to-trial phase similarity and percent change from prestimulus baseline. Group differences in poststimulus low-frequency activity and 40 Hz steady-state response were evaluated. Several EEG sensor analysis strategies were also examined. Poststimulus low-frequency group differences were observed across all methods. Given an age-related decrease in left STG 40 Hz steady-state activity in HC (HC > SZ), 40 Hz steady-state group differences were evident only in younger participants' source measures. Findings thus indicated that optimal data collection and analysis methods depend on the auditory encoding measure of interest. In addition, whereas results indicated that HC and SZ auditory encoding low-frequency group differences are generally comparable across modality and analysis strategy (and thus not dependent on obtaining construct-valid measures of left and right auditory cortex activity), 40 Hz steady-state group-difference findings are much more dependent on analysis strategy, with 40 Hz steady-state source-space findings providing the best group differentiation. PMID- 29570817 TI - Red blood cell alloimmunization in sickle cell disease: assessment of transfusion protocols during two time periods. AB - BACKGROUND: Prevention of red blood cell (RBC) alloimmunization in patients with sickle cell disease (SCD) focuses on phenotypic RBC matching. We assessed alloimmunization among transfused patients with SCD after implementing leukoreduction and prophylactic antigen matching (PAM). STUDY DESIGN AND METHODS: Retrospective review of transfusion and medical records for SCD patients 18 months to 81 years of age was performed covering two 5-year periods: Period 1, no PAM, occasional leukoreduction, and Period 2, consistent leukoreduction and extended PAM (Rh, Kell, S, Fy, Jk) for patients already alloimmunized. Patients transfused in Period 1 were excluded from Period 2. RESULTS: A total of 293 patients were transfused in Period 1 and 183 in Period 2. Median time between first sample and last type and screen after transfusion was 2.12 years in Period 1 and 1.03 years in Period 2. Initial alloimmunization prevalence was lower in Period 2 (26.2%) versus Period 1 (37.5%) and after subsequent transfusions in Period 2 (23.8%) versus Period 1 (45.7%), although without significant difference after adjusting for number of units transfused, percentage of leukoreduced RBCs, sex, and age. Alloimmunized patients received more nonleukoreduced RBCs in Period 1 than nonalloimmunized. Patients transfused during inflammatory conditions were not significantly more likely to become alloimmunized. CONCLUSIONS: The prevalence of initial and subsequent RBC alloimmunization in Period 2 was lower than that in Period 1; however, overall prevalence remained high. We recommend leukoreduced, hemoglobin S-negative Rh and Kell PAM RBCs for transfusion of patients with SCD. Component and recipient factors affecting alloimmunization should be studied further. PMID- 29570816 TI - Passive warming effect on soil microbial community and humic substance degradation in maritime Antarctic region. AB - Although the maritime Antarctic has undergone rapid warming, the effects on indigenous soil-inhabiting microorganisms are not well known. Passive warming experiments using open-top chamber (OTC) have been performed on the Fildes Peninsula in the maritime Antarctic since 2008. When the soil temperature was measured at a depth of 2-5 cm during the 2013-2015 summer seasons, the mean temperature inside OTC (OTC-In) increased by approximately 0.8 degrees C compared with outside OTC (OTC-Out), while soil chemical and physical characteristics did not change. Soils (2015 summer) from OTC-In and OTC-Out were subjected to analysis for change in microbial community and degradation rate of humic substances (HS, the largest pool of recalcitrant organic carbon in soil). Archaeal and bacterial communities in OTC-In were minimally affected by warming compared with those in OTC-Out, with archaeal methanogenic Thermoplasmata slightly increased in abundance. The abundance of heterotrophic fungi Ascomycota was significantly altered in OTC-In. Total bacterial and fungal biomass in OTC-In increased by 20% compared to OTC-Out, indicating that this may be due to increased microbial degradation activity for soil organic matter (SOM) including HS, which would result in the release of more low-molecular-weight growth substrates from SOM. Despite the effects of warming on the microbial community over the 8-years-experiments warming did not induce any detectable change in content or structure of polymeric HS. These results suggest that increased temperature may have significant and direct effects on soil microbial communities inhabiting maritime Antarctic and that soil microbes would subsequently provide more available carbon sources for other indigenous microbes. PMID- 29570818 TI - Identification of differentially expressed small RNAs and prediction of target genes in Italian Large White pigs with divergent backfat deposition. AB - The identification of the molecular mechanisms regulating pathways associated with the potential for fat deposition in pigs can lead to the detection of key genes and markers for the genetic improvement of fat traits. Interactions of microRNAs (miRNAs) with target RNAs regulate gene expression and modulate pathway activation in cells and tissues. In pigs, miRNA discovery is far from saturation, and the knowledge of miRNA expression in backfat tissue and particularly of the impact of miRNA variations is still fragmentary. Using RNA-seq, we characterized the small RNA (sRNA) expression profiles in Italian Large White pig backfat tissue. Comparing two groups of pigs divergent for backfat deposition, we detected 31 significant differentially expressed (DE) sRNAs: 14 up-regulated (including ssc-miR-132, ssc-miR-146b, ssc-miR-221-5p, ssc-miR-365-5p and the moRNA ssc-moR-21-5p) and 17 down-regulated (including ssc-miR-136, ssc-miR-195, ssc-miR-199a-5p and ssc-miR-335). To understand the biological impact of the observed miRNA expression variations, we used the expression correlation of DE miRNA target transcripts expressed in the same samples to define a regulatory network of 193 interactions between DE miRNAs and 40 DE target transcripts showing opposite expression profiles and being involved in specific pathways. Several miRNAs and mRNAs in the network were found to be expressed from backfat related pig QTL. These results are informative for the complex mechanisms influencing fat traits, shed light on a new aspect of the genetic regulation of fat deposition in pigs and facilitate the prospective implementation of innovative strategies of pig genetic improvement based on genomic markers.

PMID- 29570820 TI - Analysis of genetic relatedness among Indian cattle (Bos indicus) using genotyping-by-sequencing markers. AB - Genetic relatedness of 24 animals belonging to seven Indian cattle breeds was studied using high throughput genotyping-by-sequencing (GBS) markers. GBS produced 93.6 million reads with an average of about 3.9 million reads per animal. A total of 107 488 SNPs were identified in these individuals. When only one SNP per read was considered, a total of 60 261 SNPs representing independent reads were identified with an average SNP-to-SNP distance of 45 kb across the bovine reference genome. About 24% of the GBS-SNP markers were more than 100 kb apart. Of these, 58 322 SNPs mapped to autosomes, 1645 to the X chromosome and 28 to the Y chromosome. The average SNP-to-SNP distance on the X chromosome was 91.3 kb, whereas on the Y chromosome it was 1546.4 kb. The minor allele frequency within the Indian cattle varied from 0.103 (Ongole) to 0.177 (Siri), whereas Holstein cattle had the lowest value of 0.089. This is the first application of GBS in cattle of South Asia. The baseline information generated in this study might prompt implementation of GBS in breeding of cattle belonging to this region.

AB - BACKGROUND: Rates of metastatic progression (MP) and prostate cancer mortality (PCSM) are variable after biochemical recurrence (BCR) in patients who underwent radical prostatectomy (RP). To describe long-term oncological outcomes of BCR patients and to analyze risk factors for further outcomes in these men with a special focus on RP-BCR time. METHODS: We retrospectively analyzed the data of 5509 RP patients treated between 1992 and 2006. Of those, we included 1321 patients who experienced BCR (PSA level >=0.2 ng/mL) and did not receive any neoadjuvant or adjuvant therapy. Kaplan-Meier and time dependent Cox regression models were used. RESULTS: Median follow-up was 121 months. MP was recorded in 177 (13.4%), PCSM in 126 (9.5%), and overall mortality (OM) in 264 (20.0%) patients. Patients with MP had worse tumor characteristics such as higher Gleason Scores (GS), rapid PSA doubling-time (DT), and shorter RP-BCR time intervals. MP free, PCSM-free, and overall survival rates were significantly worse in patients with RP-BCR time of <12 months versus patients with 12-35.9 or >=36 months (P <= 0.001). Besides higher GS and rapid PSA-DT, RP-BCR time independently predicted MP, PCSM, and OM in multivariable regression analyses. Relative to the intermediate and longest RP-BCR time interval, the shortest interval (<12) carried the highest risk for all three endpoints. CONCLUSIONS: Only a small proportion of BCR patients proceed to MP or PCSM. Besides higher GS and rapid PSA DT a shorter RP-BCR interval (<12 months) heralds the most aggressive phenotype for progression to all three examined endpoints: MP, PCSM, and OM. PMID- 29570822 TI - Type 1 innate lymphoid cell aggravation of atherosclerosis is mediated through TLR4. AB - ILC populations elaborate a similar cytokine expression pattern with helper T cell subsets Th1, Th2 and Th17. Recent studies indicate that CD25+ILC2 could alleviate atherosclerosis by altering lipid metabolism, whereas the depletion of CD90-expressing ILCs had no influence on atherosclerosis. Thus, these findings raise the question of whether ILC1 cells react on atherosclerosis. Hence, our group attempted to explore the role of ILC1 cells in atherosclerosis. We found that ILC1 cells have a high Th1-like gene expression of T-bet and IFN-gamma, which is distinct from ILC2, ILC3 or conventional NK (cNK) cells. Moreover, atherosclerotic lesions were greatly reduced in ApoE-/-Rag1-/- mice treated with anti-NK1.1 mAbs for depleting ILC1 cells (ILC1+cNK cells), compared to ApoE-/ Rag1-/- mice treated with anti-IL-15R mAbs for depleting cNK cells, and these effects could be fully rescued through the adoptive transfer of ILC1 cells sorted from the spleen of ApoE-/-TLR4+/+ mice into ApoE-/-Rag1-/- mice treated with anti NK1.1 mAbs. However, the adoptive transfer of ILC1 cells sorted from the spleen of ApoE-/-TLR4-/- mice into ApoE-/-Rag1-/- mice treated with anti-NK1.1 mAbs blocked the progression of atherosclerosis, indicating that the pro atherosclerotic role of ILC1 cells is dependent on TLR4. Furthermore, oxLDL induced increase in IFN-gamma expression from ApoE-/- ILC1 cells was correlated with the decrease in BACH2 expression. Taken together, ILC1 cells exist in atherosclerosis and aggravate atherosclerosis via increasing pro-inflammatory cytokine expression in a TLR4/BACH2-dependent manner. PMID- 29570823 TI - A pediatric case of squamous cell cancer in situ in the setting of sclerodermatous graft-versus-host disease and voriconazole treatment. AB - Sclerodermatous graft-versus-host disease is a subtype of cutaneous chronic graft versus-host disease that is characterized by sclerosis of the skin and subcutaneous tissue, resulting in debilitating contractures, among other life threatening complications. Children with sclerodermatous graft-versus-host disease are at high risk of developing nonmelanoma skin cancer because of several risk factors, including young age at transplantation, prolonged immunosuppression, and exposure to photosensitizing antimicrobial prophylaxis such as voriconazole. The immunosuppression required to treat sclerodermatous graft-versus-host disease makes effectively treating nonmelanoma skin cancer and sclerodermatous graft-versus-host disease in the same patient challenging. We describe a challenging case of a 6-year-old boy with a history of sclerodermatous graft-versus-host disease and voriconazole exposure presenting with squamous cell carcinoma in situ on the left temple and actinic keratoses on the scalp treated with topical chemotherapy agents. PMID- 29570825 TI - A Bayesian Analysis of Abundance, Trend, and Population Viability for Harbor Seals in Iliamna Lake, Alaska. AB - Harbor seals in Iliamna Lake, Alaska, are a small, isolated population, and one of only two freshwater populations of harbor seals in the world, yet little is known about their abundance or risk for extinction. Bayesian hierarchical models were used to estimate abundance and trend of this population. Observational models were developed from aerial survey and harvest data, and they included effects for time of year and time of day on survey counts. Underlying models of abundance and trend were based on a Leslie matrix model that used prior information on vital rates from the literature. We developed three scenarios for variability in the priors and used them as part of a sensitivity analysis. The models were fitted using Markov chain Monte Carlo methods. The population production rate implied by the vital rate estimates was about 5% per year, very similar to the average annual harvest rate. After a period of growth in the 1980s, the population appears to be relatively stable at around 400 individuals. A population viability analysis assessing the risk of quasi-extinction, defined as any reduction to 50 animals or below in the next 100 years, ranged from 1% to 3%, depending on the prior scenario. Although this is moderately low risk, it does not include genetic or catastrophic environmental events, which may have occurred to the population in the past, so our results should be applied cautiously.

AB - People's past experiences with a hazard theoretically influence how they approach future risks. Yet, past hazard experience has been conceptualized and measured in wide-ranging, often simplistic, ways, resulting in mixed findings about its relationship with risk perception. This study develops a scale of past hazard experiences, in the context of tornadoes, that is content and construct valid. A conceptual definition was developed, a set of items were created to measure one's most memorable and multiple tornado experiences, and the measures were evaluated through two surveys of the public who reside in tornado-prone areas. Four dimensions emerged of people's most memorable experience, reflecting their awareness of the tornado risk that day, their personalization of the risk, the intrusive impacts on them personally, and impacts experienced vicariously through others. Two dimensions emerged of people's multiple experiences, reflecting common types of communication received and negative emotional responses. These six dimensions are novel in that they capture people's experience across the timeline of a hazard as well as intangible experiences that are both direct and indirect. The six tornado experience dimensions were correlated with tornado risk perceptions measured as cognitive-affective and as perceived probability of consequences. The varied experience-risk perception results suggest that it is important to understand the nuances of these concepts and their relationships. This study provides a foundation for future work to continue explicating past hazard experience, across different risk contexts, and for understanding its effect on risk assessment and responses. PMID- 29570827 TI - miR-376b-3p attenuates mitochondrial fission and cardiac hypertrophy by targeting mitochondrial fission factor. AB - Mitochondrial dysfunction contributes to the pathogenesis of cardiac hypertrophy. The disequilibrium of mitochondrial dynamic, which refers to mitochondrial fusion and fission, leads to mitochondrial morphology alteration and dysfunction. Enhanced understanding of the molecular mechanisms in depth may shed light on the therapy of the disease. In this study, we show that mitochondrial fission factor (MFF) is up-regulated upon hypertrophic agonist noradrenaline (NA) treatment. Knockdown of MFF attenuated NA induced mitochondrial fission and cardiac hypertrophy. Mitochondrial fission factor is a direct target of miR-376b-3p, which attenuated expression enhanced MFF expression through binding to its 3'UTR. Expression of miR-376b-3p weakened the fragmentation of mitochondria as well as decreased hypertrophic response through regulating MFF in NA treated neonatal rat ventricular cells (NRVCs). This study suggested that miR-376b-3p is a novel modulator affecting mitochondrial morphology through targeting MFF. PMID- 29570828 TI - Effect of the insect phenoloxidase on the metabolism of l-DOPA. AB - Insect prophenoloxidase (PPO) induces melanization around pathogens. Before melanization, PPO is cleaved into phenoloxidase (PO) by serine proteases. Insect PPO can also be activated by exogenous proteases secreted by pathogens as well as by other compounds, such as ethanol and cetylpyridinium chloride (CPC). However, the effect of these activators on the activity of PO is unclear. In this study, the insect endogenous serine protease AMM1, alpha-chymotrypsin, and ethanol were used to activate recombinant Drosophila PPO1 (rPPO1), and the PO activity differed depending on the activator applied. The PO-induced intermediates during melanization also varied markedly in their numbers and abundances. Therefore, this study indicates that the mechanism of PPO activation influences PO activity. It also suggests that PO-induced different intermediates may affect the antibacterial activity during melanization due to their toxicity. PMID- 29570829 TI - Gonadal histology of box jellyfish (Cnidaria: Cubozoa) reveals variation between internal fertilizing species Alatina alata (Alatinidae) and Copula sivickisi (Tripedaliidae). AB - Cubozoans (box jellyfish) are gonochoristic cnidarians with distinct reproductive strategies. This comparative histological study examines the gonad organization of Alatina alata and Copula sivickisi, two box jellyfish species that exhibit different modes of internal fertilization. A. alata reproduces via spermcasting aggregations while C. sivickisi reproduces via copulation; in both cases, internal fertilization occurs in the gastrovascular cavity. Herein, we provide the first histological description of subgastric sacs-structures unique to C. sivickisi. Although previously thought to function as sperm storage sacs, our findings reveal that subgastric sacs are nematocyst nests lacking sperm entirely. Conversely, we discovered that velarial spots in C. sivickisi females correspond to actual sperm storage structures. Histological examination of cubozoan sperm packages revealed that while sperm packages from both species have motile flagella, A. alata males produce nonencapsulated sperm bundles (i.e., "spermatozeugmata"), and C. sivickisi males produce encapsulated packages (i.e., "spermatophores"). Our findings corroborate the presence of several types of nematocysts in C. sivickisi embryo strands and spermatophores, and indicate their provenance to be both female and male gonads respectively, as well as subgastric sacs (i.e., nematocyst nests). In contrast to our findings of velarial spots as sperm storages structures in C. sivickisi females, and of nematocysts in the gonads of both sexes, we report that A. alata medusae lack both sperm storage structures and gonadal nematocysts. Finally, we discuss our findings on reproductive morphology of C. sivickisi and A. alata in light of the respective reproductive behavior of these two cubozoan species. PMID- 29570830 TI - Familial Blau syndrome without uveitis caused by a novel mutation in the nucleotide-binding oligomerization domain-containing protein 2 gene with good response to infliximab. AB - The proband in this study was a 4-year-old Mexican girl with Blau syndrome. She and her affected family members had skin rash and arthritis but no uveitis. Exome sequencing and DNA direct sequencing from blood samples revealed a novel nucleotide-binding oligomerization domain-containing protein 2 gene mutation in the affected family members. This study is the first report of a Mexican family with Blau syndrome showing good infliximab treatment response. The novel mutation in the nucleotide-binding oligomerization domain-containing protein 2 gene (c.1808A>G) enriches the mutation spectrum in Blau syndrome. This family represents one of the few cases of autosomal Blau syndrome with no uveitis; because of phenotype variability, it is important to recognize Blau syndrome's clinical spectrum and recommend genetic consultation. PMID- 29570831 TI - Combinations of Simple Mechanisms Explain Diverse Strategies in the Freehand Writing of Memorized Sentences. AB - Individual differences in the strategies that control sequential behavior were investigated in an experiment in which participants memorized sentences and then wrote them by hand, in a non-cursive style. Thirty-two participants each wrote eight sentences, which had hierarchical structures with five levels. The dataset included over 31,000 letters. Despite the deliberately constrained nature of the task and stimuli, 23 patterns of behavior were identified from the durations of pauses that occurred before the inscription of letters at four chunk levels, spanning letters, words, phrases, and sentences. A critical path task analytic model, Graphical Production of Memorized Sentences (GPoMS), shows that the control of writing relies on cues that continuously switch between motor actions and chunk retrievals in a just-in-time fashion at the level of letter information. GPoMS explains the individual differences in terms of variants of a motor production mechanism and variants of a chunk retrieval mechanism, which involve varying degrees of parallelism between cognitive actions and motor actions. A graphical technique for constructing GPoMS models was developed that enabled the estimation of ongoing working memory demands during production. PMID- 29570832 TI - Development of Mimokines, chemokine N terminus-based CXCR4 inhibitors optimized by phage display and rational design. AB - The chemokine receptor CXCR4 (C-X-C chemokine receptor type 4 also known as fusin or CD184 (cluster of differentiation 184)) is implicated in various biological and pathological processes of the hematopoietic and immune systems. CXCR4 is also one of the major coreceptors for HIV-1 entry into target cells and is overexpressed in many cancers, supporting cell survival, proliferation, and migration. CXCR4 is thus an extremely relevant drug target. Among the different strategies to block CXCR4, chemokine-derived peptide inhibitors hold great therapeutic potential. In this study, we used the N-terminus of vCCL2/vMIPII, a viral CXCR4 antagonist chemokine, as a scaffold motif to engineer and select CXCR4 peptide inhibitors, called Mimokines, which imitate the chemokine-binding mode but display an enhanced receptor affinity, antiviral properties, and receptor selectivity. We first engineered a Mimokine phage displayed library based on the first 21 residues of vCCL2, in which cysteine 11 and 12 were fully randomized and screened it against purified CXCR4 stabilized in liposomes. We identified Mimokines displaying up to 4-fold higher affinity for CXCR4 when compared to the reference peptide and fully protected MT-4 cells against HIV-1 infection. These selected Mimokines were then subjected to dimerization, D-amino acid, and aza-beta3-amino acid substitution to further enhance their potency and selectivity. Optimized Mimokines exhibited up to 120-fold enhanced CXCR4 binding (range of 20 nM) and more than 200-fold improved antiviral properties (<= 1 MUM) compared to the parental Mimokines. Interestingly, these optimized Mimokines also showed up to 25-fold weaker affinity for ACKR3/CXCR7 and may therefore serve as lead compounds for further development of more selective CXCR4 peptide inhibitors and probes. PMID- 29570833 TI - Online Information Sharing About Risks: The Case of Organic Food. AB - Individuals have to make sense of an abundance of information to decide whether or not to purchase certain food products. One of the means to sense-making is information sharing. This article reports on a quantitative study examining online information sharing behavior regarding the risks of organic food products. An online survey among 535 respondents was conducted in the Netherlands to examine the determinants of information sharing behavior, and their relationships. Structural equation modeling was applied to test both the measurement model and the structural model. Results showed that the intention to share information online about the risks of organic food was low. Conversations and email were the preferred channels to share information; of the social media Facebook stood out. The developed model was found to provide an adequate description of the data. It explained 41% of the variance in information sharing. Injunctive norms and outcome expectancies were most important in predicting online information sharing, followed by information-related determinants. Risk perception-related determinants showed a significant, but weak, positive relationship with online information sharing. Implications for authorities communicating on risks associated with food are addressed. PMID- 29570834 TI - Successful treatment of severe subacute cutaneous lupus erythematosus with rituximab in an adolescent. AB - Subacute cutaneous lupus erythematosus is rare in children. Most patients respond well to conventional therapy with prednisone, hydroxychloroquine, or both. Other case reports and small series have reported successful clearance with rituximab in adults. We report an adolescent who obtained remission with rituximab after failing conventional therapy. PMID- 29570835 TI - Influence of diabetes on tissue healing in orthopaedic injuries. AB - Diabetes is a group of metabolic diseases characterized by hyperglycaemia resulting from the defective action or secretion of insulin. Chronic hyperglycaemia can lead to the damage, dysfunction and failure of various organs. In the context of complications of healing and orthopaedic rehabilitation, vascular (microangiopathy) and nerve (neuropathy) disorders deserve particular attention. About 12% of the patients admitted to orthopaedic departments have diabetes. Studies indicate that there is an indisputable link between diabetes and: an increased risk of fractures, the difficult healing of injuries of bones, ligaments and musculotendinous. It appears that one of the main reasons for this is non-enzymatic glycosylation (glycation) of collagen molecules, a phenomenon observed in the elderly and diabetic populations, as it leads to the formation of advanced glycation end products (AGEs). Collagen is one of the major connective tissue components, and is therefore part of ligaments, tendons and bones. AGEs affect the weakening of its structure and biomechanical properties, and thus also affects the weakening of the structure and properties of the above-mentioned tissues. The aim of the study is to undertake an overview of the current knowledge of the impact of diabetes on the risk of some injuries and subsequent healing and rehabilitation of patients following orthopaedic injuries. PMID- 29570837 TI - Due Process in Dual Process: Model-Recovery Simulations of Decision-Bound Strategy Analysis in Category Learning. AB - Behavioral evidence for the COVIS dual-process model of category learning has been widely reported in over a hundred publications (Ashby & Valentin, ). It is generally accepted that the validity of such evidence depends on the accurate identification of individual participants' categorization strategies, a task that usually falls to Decision Bound analysis (Maddox & Ashby, ). Here, we examine the accuracy of this analysis in a series of model-recovery simulations. In Simulation 1, over a third of simulated participants using an Explicit (conjunctive) strategy were misidentified as using a Procedural strategy. In Simulation 2, nearly all simulated participants using a Procedural strategy were misidentified as using an Explicit strategy. In Simulation 3, we re-examined a recently reported COVIS-supporting dissociation (Smith et al., ) and found that these misidentification errors permit an alternative, single-process, explanation of the results. Implications for due process in the future evaluation of dual process theories, including recommendations for future practice, are discussed. PMID- 29570836 TI - Spatial Vulnerability of Network Systems under Spatially Local Hazards. AB - A hazard is often spatially local in a network system, but its impact can spread out through network topology and become global. To qualitatively and quantitatively assess the impact of spatially local hazards on network systems, this article develops a new spatial vulnerability model by taking into account hazard location, area covered by hazard, and impact of hazard (including direct impact and indirect impact), and proposes an absolute spatial vulnerability index (ASVI) and a relative spatial vulnerability index (RSVI). The relationship between the new model and some relevant traditional network properties is also analyzed. A case study on the spatial vulnerability of the Chinese civil aviation network system is conducted to demonstrate the effectiveness of the model, and another case study on the Beijing subway network system to verify its relationship with traditional network properties. PMID- 29570838 TI - Frog tendon structure and its relationship with locomotor modes. AB - Tendon collagen fibrils are the basic force-transmitting units of the tendon. Yet, surprisingly little is known about the diversity in tendon anatomy and ultrastructure, and the possible relationships between this diversity and locomotor modes utilized. Our main objectives were to investigate: (a) the ultra structural anatomy of the tendons in the digits of frogs; (b) the diversity of collagen fibril diameters across frogs with different locomotor modes; (c) the relationship between morphology, as expressed by the morphology of collagen fibrils and tendons, and locomotor modes. To assess the relationship between morphology and the locomotor modes of the sampled taxa we performed a principal component analysis considering body length, fibrillar cross sectional area (CSA) and tendon CSA. A MANOVA showed that differences between species with different locomotor modes were significant with collagen fibril diameter being the discriminating factor. Overall, our data related the greatest collagen fibril diameter to the most demanding locomotor modes, conversely, the smallest collagen fibril CSA and the highest tendon CSA were observed in animals showing a hopping locomotion requiring likely little absorption of landing forces given the short jump distances. PMID- 29570841 TI - Selection of reference genes for tissue/organ samples on day 3 fifth-instar larvae in silkworm, Bombyx mori. AB - The silkworm, Bombyx mori, is one of the world's most economically important insect. Surveying variations in gene expression among multiple tissue/organ samples will provide clues for gene function assignments and will be helpful for identifying genes related to economic traits or specific cellular processes. To ensure their accuracy, commonly used gene expression quantification methods require a set of stable reference genes for data normalization. In this study, 24 candidate reference genes were assessed in 10 tissue/organ samples of day 3 fifth instar B. mori larvae using geNorm and NormFinder. The results revealed that, using the combination of the expression of BGIBMGA003186 and BGIBMGA008209 was the optimum choice for normalizing the expression data of the B. mori tissue/organ samples. The most stable gene, BGIBMGA003186, is recommended if just one reference gene is used. Moreover, the commonly used reference gene encoding cytoplasmic actin was the least appropriate reference gene of the samples investigated. The reliability of the selected reference genes was further confirmed by evaluating the expression profiles of two cathepsin genes. Our results may be useful for future studies involving the quantification of relative gene expression levels of different tissue/organ samples in B. mori.

The discordant role in neurons and astrocytes. AB - Members of the transglutaminase family catalyze the formation of isopeptide bonds between a polypeptide-bound glutamine and a low molecular weight amine (e.g., spermidine) or the E-amino group of a polypeptide-bound lysine. Transglutaminase 2 (TG2), a prominent member of this family, is unique because in addition to being a transamidating enzyme, it exhibits numerous other activities. As a result, TG2 plays a role in many physiological processes, and its function is highly cell type specific and relies upon a number of factors, including conformation, cellular compartment location, and local concentrations of Ca2+ and guanine nucleotides. TG2 is the most abundant transglutaminase in the central nervous system (CNS) and plays a pivotal role in the CNS injury response. How TG2 affects the cell in response to an insult is strikingly different in astrocytes and neurons. In neurons, TG2 supports survival. Overexpression of TG2 in primary neurons protects against oxygen and glucose deprivation (OGD)-induced cell death and in vivo results in a reduction in infarct volume subsequent to a stroke. Knockdown of TG2 in primary neurons results in a loss of viability. In contrast, deletion of TG2 from astrocytes results in increased survival following OGD and improved ability to protect neurons from injury. Here, a brief overview of TG2 is provided, followed by a discussion of the role of TG2 in transcriptional regulation, cellular dynamics, and cell death. The differing roles TG2 plays in neurons and astrocytes are highlighted and compared to how TG2 functions in other cell types. PMID- 29570843 TI - Molecular changes in the absence of severe pathology in the pulvinar in dementia with Lewy bodies. AB - BACKGROUND: Dementia with Lewy bodies is characterized by transient clinical features, including fluctuating cognition and visual hallucinations, implicating dysfunction of cerebral hub regions, such as the pulvinar nuclei of the thalamus. However, the pulvinar is typically only mildly affected by Lewy body pathology in dementia with Lewy bodies, suggesting additional factors may account for its proposed dysfunction. METHODS: We conducted a comprehensive analysis of postmortem pulvinar tissue using whole-transcriptome RNA sequencing, protein expression analysis, and histological evaluation. RESULTS: We identified 321 transcripts as significantly different between dementia with Lewy bodies cases and neurologically normal controls, with gene ontology pathway analysis suggesting the enrichment of transcripts related to synapses and positive regulation of immune functioning. At the protein level, proteins related to synaptic efficiency were decreased, and general synaptic markers remained intact. Analysis of glial subpopulations revealed astrogliosis without activated microglia, which was associated with synaptic changes but not neurodegenerative pathology. DISCUSSION: These results indicate that the pulvinar, a region with relatively low Lewy body pathological burden, manifests changes at the molecular level that differ from previous reports in a more severely affected region. We speculate that these alterations result from neurodegenerative changes in regions connected to the pulvinar and likely contribute to a variety of cognitive changes resulting from decreased cortical synchrony in dementia with Lewy bodies.

PMID- 29570844 TI - Maintenance of redox balance by antioxidants in hemolymph of the greater wax moth Galleria mellonella larvae during encapsulation response. AB - The lipid peroxidation process in hemocytes, activities of phenoloxidase and key enzymatic antioxidants (superoxide dismutase, glutathione-S-transferase, catalase) and nonenzymatic antioxidants (thiols, ascorbate) in hemolymph of the greater wax moth Galleria mellonella L. (Lepidoptera: Pyralidae) were studied during the encapsulation process of nylon implants. It has been established that as soon as 15 min after piercing a cuticle with the implant, a capsule is formed on its surface. Active melanization of the capsule has been shown to last for 4 h. During the first hours after incorporating the implant, an increase in phenoloxidase activity and lipid peroxidation in the insect hemocytes has been revealed. Adhesion and degranulation on the surface of foreign object lead to the depletion of total hemocytes count (THC). Our results indicated that thiols and ascorbate molecules take part in the immediate antioxidant response, during later stages of encapsulation process hemolymph glutathione-S-transferase detoxifies and protects insect organism thereby restoring the internal redox balance. We suggest that nonenzymatic and enzymatic antioxidants of hemolymph plasma play a key role in the maintenance of redox balance during encapsulation of foreign targets. PMID- 29570845 TI - Melatonin and cardioprotection against ischaemia/reperfusion injury: What's new? A review. AB - Melatonin is a pleiotropic hormone with several functions. It binds to specific receptors and to a number of cytosolic proteins, activating a vast array of signalling pathways. Its potential to protect the heart against ischaemia/reperfusion damage has attracted much attention, particularly in view of its possible clinical applications. This review will focus mainly on the possible signalling pathways involved in melatonin-induced cardioprotection. In particular, the role of the melatonin receptors and events downstream of receptor activation, for example, the reperfusion injury salvage kinase (RISK), survivor activating factor enhancement (SAFE) and Notch pathways, the sirtuins, nuclear factor E2-related factor 2 (Nrf2) and translocases in the outer membrane (TOM70) will be discussed. Particular attention is given to the role of the mitochondrion in melatonin-induced cardioprotection. In addition, a brief overview will be given regarding the status quo of the clinical application of melatonin in humans. PMID- 29570846 TI - Neuroprotective Effects of Creatine in the CMVMJD135 Mouse Model of Spinocerebellar Ataxia Type 3. AB - BACKGROUND AND OBJECTIVE: Mitochondrial dysfunction has been implicated in several neurodegenerative diseases. Creatine administration increases concentration of the energy buffer phosphocreatine, exerting protective effects in the brain. We evaluate whether a creatine-enriched diet would be beneficial for a mouse model of spinocerebellar ataxia type 3, a genetically defined neurodegenerative disease for which no treatment is available. METHODS: We performed 2 independent preclinical trials using the CMVMJD135 mouse model (treating 2 groups of animals with different disease severity) and wild-type mice, to which 2% creatine was provided for 19 (preclinical trial 1) or 29 (preclinical trial 2) weeks, starting at a presymptomatic age. Motor behavior was evaluated at several time points from 5 to 34 weeks of age, and neuropathological studies were performed at the end of each trial. RESULTS: Creatine supplementation led to an overall improvement in the motor phenotype of CMVMJD135 mice in both trials, rescuing motor balance and coordination and also restored brain weight, mitigated astrogliosis, and preserved Calbindin-positive cells in the cerebellum. Moreover, a reduction of mutant ataxin-3 aggregates occurred despite maintained steady-state levels of the protein and the absence of autophagy activation. Creatine treatment also restored the expression of the mitochondrial mass marker Porin and reduced the expression of antioxidant enzymes Heme oxygenase 1 (HO1) and NAD(P)H Quinone Dehydrogenase 1 (NQO1), suggesting a beneficial effect at the level of mitochondria and oxidative stress. CONCLUSIONS: Creatine slows disease progression and improves motor dysfunction as well as ameliorates neuropathology of the CMVMJD135 animals, supporting this as a useful strategy to slow the progression of spinocerebellar ataxia type 3.

PMID- 29570848 TI - Quality of Life in Huntington's Disease: Critique and Recommendations for Measures Assessing Patient Health-Related Quality of Life and Caregiver Quality of Life. AB - The compromise of quality of life in Huntington's disease is a major issue, both for individuals with the disease as well as for their caregivers. The International Parkinson and Movement Disorder Society commissioned a review of the use and clinimetric validation status of measures used in Huntington's disease to assess aspects related with quality of life and to make recommendations on their use following standardized criteria. We included both patient-centered measures (patient health-related quality-of-life measures) and caregiver-centered measures (caregiver quality-of-life measures). After conducting a systematic literature search, we included 12 measures of patient health-related quality of life and 2 measures of caregiver quality of life. Regarding patient-centered measures, the Medical Outcomes Study 36-Item Short Form Health Survey is "recommended" as a generic assessment of health-related quality of life in patients with Huntington's disease. The 12-Item Short Form Health Survey, the Sickness Impact Profile, the 12-item World Health Organization Disability Assessment Schedule, and the Huntington's Disease Health-Related Quality of Life questionnaire are "suggested." No caregiver-centered quality-of life measure obtained a "recommended" status. The Alzheimer's Carer's Quality of Life Inventory and the Huntington's Disease Quality of Life Battery for Carers are "suggested." Recognizing that the assessment of patient health-related quality of life can be challenging in Huntington's disease, as patients may lack insight and there is insufficient clinimetric testing of these scales, the committee concluded that further validation of currently available health-related quality-of-life measures should be undertaken, namely, those Huntington's disease specific health-related quality-of-life measures that have recently been reported and used.

PMID- 29570849 TI - Usefulness of two- and three-dimensional transesophageal echocardiography in combined mitral valve-in-valve implantation and paraprosthetic leak closure. AB - We demonstrate the usefulness of two- and live/real time three-dimensional transesophageal echocardiography in a procedure, which combined transcatheter mitral valve-in-valve deployment and paraprosthetic leak closure in the same setting using the less invasive transfemoral approach in an adult patient with bioprosthetic mitral valve degeneration.

PMID- 29570850 TI - Physician characteristics influence the trends in resuscitation decisions at different ages. AB - AIM: We examined how physicians in different medical specialties would evaluate treatment decisions for vulnerable patients in need of resuscitation. METHODS: A survey depicting six acutely ill patients from newborn infant to aged, all in need of resuscitation with similar prognoses, was distributed (in 2009) to a representative sample of 1650 members of the Norwegian Medical Association and 676 members of the Norwegian Pediatric Association. RESULTS: There were 1335 respondents (57% participation rate). The majority of respondents across all specialties thought resuscitation was in the best interest of a 24 weeks' gestation preterm infant and would resuscitate the patient, but would also accept palliative care on the family's demand. Accepting a family's refusal of resuscitation was more common for the newborn infants. Specialists were overall similar in their answers, but specialty, age and gender were associated with different answers for the patients at both ends of the age spectrum. CONCLUSION: Resuscitation decisions for the very young do not always seem to follow the best interest principle. Specialty and personal characteristics still have an impact on how we consider important ethical issues. We must be cognisant of our own valuations and how they may influence care.

PMID- 29570853 TI - Long-term safety and efficacy of levodopa-carbidopa intestinal gel in advanced Parkinson's disease. AB - BACKGROUND: Levodopa-carbidopa intestinal gel (designated as carbidopa-levodopa enteral suspension in the United States) provides stable plasma levodopa concentrations and reduces motor fluctuations in advanced Parkinson's disease patients through continuous delivery of levodopa via percutaneous endoscopic gastrojejunostomy. We report long-term safety and efficacy outcomes from an open label phase 3 treatment program. METHODS: PD patients (n = 262) who completed a 12-week double-blind study and its 52-week open-label extension or a separate 54 week open-label study were enrolled in this ongoing phase 3 open-label, multinational study (NCT00660673). Safety and efficacy assessments were collected every 6 months. RESULTS: Mean total duration of exposure to levodopa-carbidopa intestinal gel was 4.1 years (range, 1.2 to 6.9 years). The overall discontinuation rate was 34% (average annual discontinuation rate, 10%). Although most patients (94%) reported an adverse event, the rate of adverse events decreased over time; 53% experienced a serious adverse event. Of patients in this extension study, 54% required jejunal tube replacement during the study, and 37% required percutaneous endoscopic gastrostomy tube replacement. Most patients were on levodopa monotherapy. Patients maintained reductions in "off" time and increases in mean "on" time without dyskinesia from initial levodopa-carbidopa intestinal gel infusion to he study end point (P < 0.001; n = 81). Activities of daily living and quality-of-life assessments demonstrated significant improvements that persisted through the study. CONCLUSIONS: This long-term study demonstrates sustained and clinically meaningful benefits from levodopa-carbidopa intestinal gel in advanced PD patients. Although adverse event rates decreased over time, vigilance is required for device-related complications and adverse events. (c) 2018 The Authors.

PMID- 29570854 TI - Daily melatonin protects the endothelial lineage and functional integrity against the aging process, oxidative stress, and toxic environment and restores blood flow in critical limb ischemia area in mice. AB - We tested the hypothesis that daily melatonin treatment protects endothelial lineage and functional integrity against the aging process, oxidative stress/endothelial denudation (ED), and toxic environment and restored blood flow in murine critical limb ischemia (CLI). In vitro study using HUVECs, in vivo models (ie, CLI through left femoral artery ligation and ED through carotid artery wire injury), and model of lipopolysaccharide-induced aortic injury in young (3 months old) and aged (8 months old) mice were used to elucidate effects of melatonin treatment on vascular endothelial integrity. In vitro study showed that menadione-induced oxidative stress (NOX-1/NOX-2), inflammation (TNF-alpha/NF kB), apoptosis (cleaved caspase-3/PARP), and mitochondrial damage (cytosolic cytochrome c) in HUVECs were suppressed by melatonin but reversed by SIRT3-siRNA (all P < .001). In vivo, reduced numbers of circulating endothelial progenitor cells (EPCs) (C-kit/CD31+/Sca-1/KDR+/CXCR4/CD34+), and angiogenesis (Matrigel assay of bone marrow-derived EPC and ex vivo aortic ring cultures) in older (compared with younger) mice were significantly reversed through daily melatonin administration (20 mg/kg/d, ip) (all P < .001). Aortic vasorelaxation and nitric oxide release were impaired in older mice and reversed in age-match mice receiving melatonin (all P < .01). ED-induced intimal/medial hyperplasia, reduced blood flow to ischemic limb, and angiogenesis (reduced CD31+/vWF+ cells/small vessel number) were improved after daily melatonin treatment (all P < .0001). Lipopolysaccharide-induced aortic endothelial cell detachment, which was more severe in aged mice, was also alleviated after daily melatonin treatment (P < .0001). Daily melatonin treatment protected both structural and functional integrity of vascular endothelium against aging-, oxidative stress-, lipopolysaccharide-, and ischemia-induced damage probably through upregulating the SIRT signaling pathway.

AB - OBJECTIVE: This study aims to address gaps in health conditions and unmet needs in daily activities between people with dementia (PWD) and without dementia in a developing country and to identify the variables associated with unmet needs among PWD to guide practitioners and policymakers in dealing with an increased burden of dementia. METHODS: Nationally representative data on 4655 Chileans age 60 and over were used to compare health conditions and unmet needs in daily life activities between individuals with (N = 455, 9.6%) and without dementia. Regression analysis was conducted to identify the variables associated with unmet needs among PWD. RESULTS: Overall, PWD had worse health and needed greater assistance in performing daily activities than people without dementia. Among PWD, being male was associated with more unmet needs, in both activities of daily living (ADL) and instrumental ADL. Lower educational level and fewer caregivers were associated with more unmet needs for ADL, while inferior functional ability was associated with more unmet needs for instrumental ADL. CONCLUSIONS: The results from this study call for action by practitioners and policymakers to foster caregiver training, increase supportive services, and advance care planning for PWD. PMID- 29570855 TI - Post-influenzal triazole-resistant aspergillosis following allogeneic stem cell transplantation. AB - Influenza virus infection is now recognised as a risk factor for invasive pulmonary aspergillosis (IPA). Delays in diagnosis contribute to delayed commencement of antifungal therapy. In addition, the emergence of resistance to first-line triazole antifungal agents puts emphasis on early detection to prevent adverse outcomes. We present 2 allogeneic stem cell transplant patients who developed IPA due to triazole-resistant Aspergillus fumigatus following influenza infection. We underline the challenges faced in the management of these cases, the importance of early diagnosis and need for surveillance given the emergence of triazole resistance. PMID- 29570857 TI - Isavuconazole treatment for rare fungal diseases and for invasive aspergillosis in patients with renal impairment: Challenges and lessons of the VITAL trial. AB - Invasive fungal disease (IFD) confers a substantial risk for morbidity and mortality to immunocompromised patients. Invasive aspergillosis (IA) is the most common IFD caused by moulds but the prevalence of other rare mould diseases, such as mucormycosis, hyalohyphomycosis and phaeohyphomycosis, may be increasing. Treatments are available for IA, but evidence to support efficacy and safety of antifungal agents for rare IFDs, or for IFDs in special patient populations, is limited or lacking. The VITAL trial was conducted to assess the efficacy and safety of isavuconazole for the treatment of patients with IA and renal impairment, or with IFDs caused by rare moulds, yeasts or dimorphic fungi. These patients stand to benefit most from a new treatment option but are unlikely to be included in a randomised, controlled trial. In this article, we review the challenges faced in the design and conduct of the VITAL trial. We also review the findings of VITAL, which included evidence of the efficacy and safety of isavuconazole. Finally, we consider the importance of trials such as VITAL to inform therapeutic decision making for clinicians faced with the challenge of treating patients with rare IFDs and as one paradigm of how to determine efficacy and safety of new drugs for rare and resistant infections without a suitable comparator. PMID- 29570858 TI - Metabolic control of cell fate bifurcations in a hematopoietic progenitor population. AB - Growth signals drive hematopoietic progenitor cells to proliferate and branch into divergent cell fates, but how unequal outcomes arise from a common progenitor is not fully understood. We used steady-state analysis of in vivo hematopoiesis and Fms-related tyrosine kinase 3 ligand (Flt3L)-induced in vitro differentiation of dendritic cells (DCs) to determine how growth signals regulate lineage bias. We found that Flt3L signaling induced anabolic activation and proliferation of DC progenitors, which was associated with DC differentiation. Perturbation of processes associated with quiescence and catabolism, including AMP-activated protein kinase signaling, fatty acid oxidation, or mitochondrial clearance increased development of cDC2 cells at the expense of cDC1 cells. Conversely, scavenging anabolism-associated reactive oxygen species skewed differentiation toward cDC1 cells. Sibling daughter cells of dividing DC progenitors exhibited unequal expression of the transcription factor interferon regulatory factor 8, which correlated with clonal divergence in FoxO3a signaling and population-level bifurcation of cell fate. We propose that unequal transmission of growth signals during cell division might support fate branches during proliferative expansion of progenitors. PMID- 29570859 TI - Oral lorazepam can be substituted for intravenous midazolam when weaning paediatric intensive care patients off sedation. AB - AIM: Intravenous sedatives used in the paediatric intensive care unit (PICU) need to be tapered after prolonged use to prevent iatrogenic withdrawal syndrome (IWS). We evaluated the occurrence of IWS and the levels of sedation before and after conversion from intravenous midazolam to oral lorazepam. METHODS: This was a retrospective, observational, single cohort study of children under the age of 18 admitted to the PICU of the Erasmus MC-Sophia Children's Hospital, Rotterdam, The Netherlands, between January 2013 and December 2014. The outcome parameters were the Sophia Observation withdrawal Symptoms (SOS) scale scores and COMFORT Behaviour scale scores before and after conversion. RESULTS: Of the 79 patients who were weaned, 32 and 39 had before and after SOS scores and 77 had COMFORT-B scores. IWS was reported in 15 of 79 patients (19.0%) during the 48 hours before the start of lorazepam and 17 of 79 patients (21.5%) during the 48 hours after treatment started. Oversedation was seen in 16 of 79 patients (20.3%) during the 24 hours before substitution and in 30 of 79 patients (38.0%) during the 24 hours after substitution. CONCLUSION: The weaning protocol was not able to prevent IWS in all patients, but converting from intravenous midazolam to oral lorazepam did not increase the incidence. PMID- 29570860 TI - Undifferentiated-type component mixed with differentiated-type early gastric cancer is a significant risk factor for endoscopic non-curative resection. AB - BACKGROUND AND AIM: Previous studies of surgical specimens have found that the presence of mixed histological components in differentiated-type early gastric cancer (EGC) is a risk factor for lymph node metastasis and indicates greater malignancy. As there have been no reports on its endoscopic treatment, we examined endoscopic curative resection in relation to differentiated-type predominant mixed-type (MT). METHODS: This was a single-center, retrospective study. Subjects were 2585 differentiated-type EGC in 2551 patients treated with endoscopic submucosal dissection (ESD) in our hospital between March 2005 and January 2016. These lesions comprised 2231 cases of curative resection and 354 cases of non-curative resection. Histologically, 2339 lesions were pure differentiated-type (PDT) and 246 lesions were MT. Rates of curative resection were compared, according to tumor size, between different histological types. RESULTS: When curative and non-curative cases were compared using multivariate analysis among lesions measuring <=20 mm for factors other than those determining curative resection, significant differences were obtained for tumor diameter, ulcer, and MT. Among lesions measuring 21-30 mm, ulcer and MT were associated with significant differences. Among lesions measuring >30 mm, upper region and MT were associated with significant differences. Curative resection rates, in relation to histological type among lesions measuring <=20 mm, were 93.4% for PDT and 63.4% for MT, whereas corresponding rates were 85.1% and 60.0%, respectively, among lesions measuring 21-30 mm, and 55.3% and 30.2%, respectively, among lesions measuring >30 mm. CONCLUSION: We found that MT was a risk factor for non curative resection irrespective of lesion size.

AB - Parenteral nutrition (PN) is a highly complex medication and its provision can be prone to a variety of errors. Safe administration of this therapy requires that the competency of clinicians, particularly nurses, be demonstrated using a standardized process. In this document, a standardized model for PN administration competency is proposed based on a competency framework, the ASPEN published interdisciplinary core competencies, discipline-specific standards of practice, safe practice recommendations, and clinical guidelines. ASPEN recognizes that all healthcare institutions may not currently meet the aspirational goals of this document. This framework will guide institutions and agencies in developing tools and procedures and maintaining competency of staff members around safe PN administration. The ASPEN Board of Directors has approved this document. PMID- 29570862 TI - Medical and surgical management of advanced Parkinson's disease. AB - Advanced Parkinson's disease is characterized by the presence of motor fluctuations, various degree of dyskinesia, and disability with functional impact on activities of daily living and independence. Therapeutic management aims to extend levodopa benefit while minimizing motor complications and includes, in selected cases, the implementation of drug infusion and surgical techniques. In milder forms of motor complications, these can often be controlled with manipulation of levodopa dose and the introduction of supplemental therapies such as catechol-O-methyl transferase inhibitors, monoamine oxidase B inhibitors, and dopamine agonists including apomorphine. Clinical experience and evidence from published studies indicate that when these agents cannot satisfactorily control motor complications, patients should be assessed and considered for device-aided therapies. This review article summarizes some of the newer available therapeutic opportunities such as use of enzyme inhibitors like opicapone and safinamide, adenosine A2A receptor antagonists, apomorphine and levodopa/carbidopa intestinal gel infusion, deep brain stimulation including the role of closed-loop and adaptive stimulation, and MRI-guided focused ultrasound.

AB - The "Achilles heel" of coronary artery bypass graft (CABG) surgery is graft patency. While long-term patency is determined by the type of conduit and the progression of graft and native vessel disease, short-term patency is affected by intra-operative technical issues. Transit-time flow measurements and epicardial ultrasound have been shown to accurately assess intra-operative graft patency. This review will examine the evidence to support the premise that intra-operative graft assessment is essential in determining graft patency and should be the standard of care when performing CABG surgery.

AB - OBJECTIVE: The objective of this review was to update evidence-based medicine recommendations for treating motor symptoms of Parkinson's disease (PD). BACKGROUND: The Movement Disorder Society Evidence-Based Medicine Committee recommendations for treatments of PD were first published in 2002 and updated in 2011, and we continued the review to December 31, 2016. METHODS: Level I studies of interventions for motor symptoms were reviewed. Criteria for inclusion and quality scoring were as previously reported. Five clinical indications were considered, and conclusions regarding the implications for clinical practice are reported. RESULTS: A total of 143 new studies qualified. There are no clinically useful interventions to prevent/delay disease progression. For monotherapy of early PD, nonergot dopamine agonists, oral levodopa preparations, selegiline, and rasagiline are clinically useful. For adjunct therapy in early/stable PD, nonergot dopamine agonists, rasagiline, and zonisamide are clinically useful. For adjunct therapy in optimized PD for general or specific motor symptoms including gait, rivastigmine is possibly useful and physiotherapy is clinically useful; exercise-based movement strategy training and formalized patterned exercises are possibly useful. There are no new studies and no changes in the conclusions for the prevention/delay of motor complications. For treating motor fluctuations, most nonergot dopamine agonists, pergolide, levodopa ER, levodopa intestinal infusion, entacapone, opicapone, rasagiline, zonisamide, safinamide, and bilateral STN and GPi DBS are clinically useful. For dyskinesia, amantadine, clozapine, and bilateral STN DBS and GPi DBS are clinically useful. CONCLUSIONS: The options for treating PD symptoms continues to expand. These recommendations allow the treating physician to determine which intervention to recommend to an individual patient. (c) 2018 International Parkinson and Movement Disorder Society. PMID- 29570867 TI - An Outbreak of Microsporum canis infection at a military base associated with stray cat exposure and person-to-person transmission. AB - Tinea corporis caused by Microsporum canis is usually associated with exposure to animals, but outbreaks with anthropophilic transmission were described. A large outbreak in a military base was investigated. We investigated the outbreak's source and risk factors for infection in order to contain and eliminate it. All staff-members at the base were interviewed and examined. A case-control analysis of symptomatic patients was used to elucidate risk factors. Stray cats were captured and sampled. M. canis isolated from skin and fur specimens of patients and cats were genotyped by microsatellite sequencing. Fifty-three of 502 staff members were symptomatic. Logistic regression showed risk associated with female gender, cat contact at base and performance of guarding duty. Multiple stray cats were found at the base. M. canis isolates from 4 cats and 4 patients had an identical genotype, while 2 patients had different genotypes. We describe the largest M. canis outbreak reported until now. Epidemiological and phylogenetic tools were used to investigate the source of the outbreak. Multiple exposures to stray cats caused infection of mainly young female soldiers performing guarding duty. Other persons were infected by person-to-person transmission. These findings aided in the termination of the outbreak. PMID- 29570868 TI - Chronic-active antibody-mediated rejection with or without donor-specific antibodies has similar histomorphology and clinical outcome - a retrospective study. AB - Chronic-active antibody-mediated rejection (c-aABMR) is defined as histological evidence of chronic endothelial injury (cg), also known as transplant glomerulopathy, and either microvascular inflammation (MVI) or positivity for C4d. Importantly, the presence of donor-specific antibodies (DSA) is currently still mandatory for the diagnosis of c-aABMR. This retrospective study of 41 c aABMR patients investigates whether cases suspicious for c-aABMR (DSA negative, n = 24) differ from cases of c-aABMR (DSA positive, n = 17) with respect to renal histology, allograft function and long-term graft survival. All included patients had progressive loss of allograft function and were diagnosed by for cause biopsy and scored according to the Banff '15 criteria. In all DSApos cases, DSA were de novo and the majority was directed against HLA-II being mostly anti-HLA-DQ antibodies. There were no statistically significant differences in clinical characteristics, decline in allograft function and renal allograft survival in cases with or without DSAs. All cases showed chronic histomorphological damage and inflammation, irrespective of the presence of DSA. Renal histology and clinical outcome of patients suspicious for c-aABMR (DSAneg) do not significantly differ from patients with a diagnosis of c-aABMR (DSApos). We believe that our study adds to the ongoing debate regarding the need for DSAs to be present for the diagnosis of c-aABMR. PMID- 29570869 TI - Fullerene-Based Materials as Hole-Transporting/Electron-Blocking Layers: Applications in Perovskite Solar Cells. AB - Here we report for the first time an efficient fullerene-based compound, FU7, able to act as hole-transporting material (HTM) and electron blocking contact. It has been applied on perovskite solar cells (PSCs), obtaining 0.81 times the efficiency of PSCs with the standard HTM, spiro-OMeTAD, with the additional advantage that this performance is reached without any additive introduced in the HTM layer. Moreover, as a proof of concept, we have described for the first time efficient PSCs in which both selective contacts are fullerene derivatives, to obtain unprecedented "fullerene sandwich" PSCs. PMID- 29570870 TI - On the Antibacterial Activity of Azacarboxylate Ligands: Lowered Metal Ion Affinities for Bis-amide Derivatives of EDTA do not mean Reduced Activity. AB - EDTA is widely used as an inhibitor of bacterial growth, affecting the uptake and control of metal ions by microorganisms. We describe the synthesis and characterisation of two symmetrical bis-amide derivatives of EDTA, featuring glycyl or pyridyl substituents: AmGly2 and AmPy2 . Metal ion affinities (logK) have been evaluated for a range of metals (Mg2+ , Ca2+ , Fe3+ , Mn2+ , Zn2+ ), revealing less avid binding compared to EDTA. The solid-state structures of AmGly2 and of its Mg2+ complex have been determined crystallographically. The latter shows an unusual 7-coordinate, capped octahedral Mg2+ centre. The antibacterial activities of the two ligands and of EDTA have been evaluated against a range of health-relevant bacterial species, three Gram negative (Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae) and a Gram positive (Staphylococcus aureus). The AmPy2 ligand is the only one that displays a significant inhibitory effect against K. pneumoniae, but is less effective against the other organisms. AmGly2 exhibits a more powerful inhibitory effect against E. coli at lower concentrations than EDTA (<3 mm) or AmPy2 , but loses its efficacy at higher concentrations. The growth inhibition of EDTA and AmGly2 on mutant E. coli strains with defects in outer-membrane lipopolysaccharide (LPS) structures has been assessed to provide insight into the unexpected behaviour. Taken together, the results contradict the assumption of a simple link between metal ion affinity and antimicrobial efficacy. PMID- 29570871 TI - Water Splitting on Rutile TiO2 -Based Photocatalysts. AB - Water splitting using a semiconductor photocatalyst with sunlight has long been viewed as a potential means of large-scale H2 production from renewable resources. Different from anatase TiO2 , rutile enables preferential water oxidation, which is useful for the construction of a Z-scheme water-splitting system. The combination of rutile TiO2 with a suitable H2 -evolution photocatalyst such as a Pt-loaded BaZrO3 -BaTaO2 N solid solution enables solar driven water splitting into H2 and O2 . While rutile TiO2 is a wide-gap semiconductor with a bandgap of 3.0 eV, co-doping of rutile TiO2 with certain metal ions and/or nitrogen produces visible-light-driven photocatalysts, which are also useful as a component for water oxidation in visible-light-driven Z scheme water splitting. The key to achieving highly efficient water oxidation is to maintain a charge balance of dopants in the rutile, because single doping typically produces trap states that capture photogenerated electrons and/or holes. Here we provide a concise summary of rutile TiO2 -based photocatalysts for water-splitting systems. PMID- 29570872 TI - Bifunctional Squaramide Organocatalysts for the Asymmetric Addition of Formaldehyde tert-Butylhydrazone to Simple Aldehydes. AB - The nucleophilic addition of formaldehyde tert-butylhydrazone to simple aldehydes (a formal hetero-carbonyl-ene reaction) can be performed with good reactivity and excellent enantioselectivity by virtue of the dual hydrogen-bonding activation exerted by amide-squaramide organocatalysts. The resulting hydroxydiazenes (azo alcohols) were isolated in high yields as enantiomerically enriched azoxy compounds after a regioselective azo-to-azoxy transformation. Subsequent derivatization provides an entry to relevant amino alcohols, oxazolidinones, and derivatives thereof. PMID- 29570873 TI - Genomic adaptation of flowering-time genes during the expansion of rice cultivation area. AB - The diversification of flowering time in response to natural environments is critical for the spread of crops to diverse geographic regions. In contrast with recent advances in understanding the molecular basis of photoperiodic flowering in rice (Oryza sativa), little is known about how flowering-time diversification is structured within rice subspecies. By analyzing genome sequencing data and a set of 429 chromosome segment substitution lines (CSSLs) originating from 10 diverse rice accessions with wide distributions, we revealed diverse effects of allelic variations for common flowering-time quantitative trait loci in the recipient's background. Although functional variations associated with a few loci corresponded to standing variations among subspecies, the identified functional nucleotide polymorphisms occurred recently after rice subgroup differentiation, indicating that the functional diversity of flowering-time gene sequences was not particularly associated with phylogenetic relationship between rice subspecies. Intensive analysis of the Hd1 genomic region identified the signature of an early introgression of the Hd1 with key mutation(s) in aus and temperate japonica accessions. Our data suggested that, after such key introgressions, new mutations were selected and accelerated the flowering-time diversity within subspecies during the expansion of rice cultivation area. This finding may imply that new genome-wide changes for flowering-time adaptation are one of the critical determinants for establishing genomic architecture of local rice subgroups. In depth analyses of various rice genomes coupling with the genetically confirmed phenotypic changes in a large set of CSSLs enabled us to demonstrate how rice genome dynamics has coordinated with the adaptation of cultivated rice during the expansion of cultivation area. PMID- 29570875 TI - Adenosine A2A receptors modulate the dopamine D2 receptor-mediated inhibition of synaptic transmission in the mouse prefrontal cortex. AB - Prefrontal cortex (PFC) circuits are modulated by dopamine acting on D1 - and D2 like receptors, which are pharmacologically exploited to manage neuropsychiatric conditions. Adenosine A2A receptors (A2A R) also control PFC-related responses and A2A R antagonists are potential anti-psychotic drugs. As tight antagonistic A2A R-D2 R and synergistic A2A R-D1 R interactions occur in other brain regions, we now investigated the crosstalk between A2A R and D1 /D2 R controlling synaptic transmission between layers II/III and V in mouse PFC coronal slices. Dopamine decreased synaptic transmission, a presynaptic effect based on the parallel increase in paired-pulse responses. Dopamine inhibition was prevented by the D2 R like antagonist sulpiride but not by the D1 R antagonist SCH23390 and was mimicked by the D2 R agonist sumanirole, but not by the agonists of either D4 R (A-412997) or D3 R (PD128907). Dopamine inhibition was prevented by the A2A R antagonist, SCH58261, and attenuated in A2A R knockout mice. Accordingly, triple labelling immunocytochemistry experiments revealed the co-localization of A2A R and D2 R immunoreactivity in glutamatergic (vGluT1-positive) nerve terminals of the PFC. This reported positive A2A R-D2 R interaction controlling PFC synaptic transmission provides a mechanistic justification for the anti-psychotic potential of A2A R antagonists. PMID- 29570874 TI - Synthesis of Artemisinin-Derived Dimers, Trimers and Dendrimers: Investigation of Their Antimalarial and Antiviral Activities Including Putative Mechanisms of Action. AB - Generation of dimers, trimers and dendrimers of bioactive compounds is an approach that has recently been developed for the discovery of new potent drug candidates. Herein, we present the synthesis of new artemisinin-derived dimers and dendrimers and investigate their action against malaria parasite Plasmodium falciparum 3D7 strain and human cytomegalovirus (HCMV). Dimer 7 was the most active compound (EC50 1.4 nm) in terms of antimalarial efficacy and was even more effective than the standard drugs dihydroartemisinin (EC50 2.4 nm), artesunic acid (EC50 8.9 nm) and chloroquine (EC50 9.8 nm). Trimer 4 stood out as the most active agent against HCMV in vitro replication and exerted an EC50 value of 0.026 MUm, representing an even higher activity than the two reference drugs ganciclovir (EC50 2.60 MUm) and artesunic acid (EC50 5.41 MUm). In addition, artemisinin-derived dimer 13 and trimer 15 were for the first time both immobilized on TOYOPEARL AF-Amino-650M beads and used for mass spectrometry-based target identification experiments using total lysates of HCMV-infected primary human fibroblasts. Two major groups of novel target candidates, namely cytoskeletal and mitochondrial proteins were obtained. Two putatively compound binding viral proteins, namely major capsid protein (MCP) and envelope glycoprotein pUL132, which are both essential for HCMV replication, were identified. PMID- 29570876 TI - Electron-Deficient Bipyrrole Boomerangs: Bright Fluorophores Obtained via Double C-H Bond Activation. AB - PdII -mediated annulative double C-H activation is shown to efficiently convert 1,n-dipyrrolylalkanes into extensively pi-conjugated bipyrroles not accessible by conventional oxidative coupling protocols. This approach is applicable to both electron-rich and electron-deficient systems, and has been further developed into tandem processes involving further cyclization of substituents or oxygenation of pyrrolic alpha-positions. The new bipyrrole intermediates show enhanced fluorescence as well as tunable optical properties controlled by the alignment of chromophore subunits. Photophysical data, including femtosecond transient absorptions, reveal solvent-induced intramolecular charge transfer in their excited states, dependent on the polarity of the medium. PMID- 29570877 TI - Host- and stage-dependent secretome of the arbuscular mycorrhizal fungus Rhizophagus irregularis. AB - Arbuscular mycorrhizal fungi form the most wide-spread endosymbiosis with plants. There is very little host specificity in this interaction, however host preferences as well as varying symbiotic efficiencies have been observed. We hypothesize that secreted proteins (SPs) may act as fungal effectors to control symbiotic efficiency in a host-dependent manner. Therefore, we studied whether arbuscular mycorrhizal (AM) fungi adjust their secretome in a host- and stage dependent manner to contribute to their extremely wide host range. We investigated the expression of SP-encoding genes of Rhizophagus irregularis in three evolutionary distantly related plant species, Medicago truncatula, Nicotiana benthamiana and Allium schoenoprasum. In addition we used laser microdissection in combination with RNA-seq to study SP expression at different stages of the interaction in Medicago. Our data indicate that most expressed SPs show roughly equal expression levels in the interaction with all three host plants. In addition, a subset shows significant differential expression depending on the host plant. Furthermore, SP expression is controlled locally in the hyphal network in response to host-dependent cues. Overall, this study presents a comprehensive analysis of the R. irregularis secretome, which now offers a solid basis to direct functional studies on the role of fungal SPs in AM symbiosis. PMID- 29570878 TI - Genetic diversity and evolution of reduced sulfur storage during domestication of maize. AB - The domestication of maize has spanned a period of over 9000 years, during which time its wild relative teosinte underwent natural and artificial selection. We hypothesize that environmental conditions could have played a major role in this process. One factor of environmental variation is soil composition, which includes sulfur availability. Sulfur is reduced during photosynthesis and is used to synthesize cysteine and methionine, which drive the accumulation of delta10 (Zm00001d045937), delta18 (Zm00001d037436), beta15 (Zm00001d035760), gamma16 (Zm00001d005793), gamma27 (Zm00001d020592), and gamma50 (Zm00001d020591) zeins, representing the zein2 fraction (z2) of storage proteins in maize seeds. In this study, polymorphisms and haplotypes were detected based on six z2 genes in 60 maize and teosintes lines. Haplotypes were unevenly distributed, and abundant genetic diversity was found in teosintes. Polymorphism was highest in z2delta18, whereas for z2beta15 single nucleotide polymorphism (SNP) density and insertion/deletion (indel) abundance were the lowest, indicating differential roles in seed evolution. Indels showed a clustered distribution, and most of these derived from teosintes. The indels not only led to tandem repeat polymorphisms, but also to frameshift mutations, which could also be used as null variants. In addition, neutral evolutionary tests, phylogenetic analyses, and population structures indicated that z2delta10 and z2gamma50 had undergone natural selection. Indeed, a natural selection imprint could also be found with z2gamma27 and z2gamma16, whereas z2delta18 and z2beta15 tended to be under neutral evolution. These results suggested that genetic diversity and evolution of a subset of sulfur-rich zeins could be under environmental adaptation during maize domestication. PMID- 29570879 TI - The E3 ubiquitin ligase SP1-like 1 plays a positive role in peroxisome biogenesis in Arabidopsis. AB - Peroxisomes are dynamic organelles crucial for a variety of metabolic processes during the development of eukaryotic organisms, and are functionally linked to other subcellular organelles, such as mitochondria and chloroplasts. Peroxisomal matrix proteins are imported by peroxins (PEX proteins), yet the modulation of peroxin functions is poorly understood. We previously reported that, besides its known function in chloroplast protein import, the Arabidopsis E3 ubiquitin ligase SP1 (suppressor of ppi1 locus1) also targets to peroxisomes and mitochondria, and promotes the destabilization of the peroxisomal receptor-cargo docking complex components PEX13 and PEX14. Here we present evidence that in Arabidopsis, SP1's closest homolog SP1-like 1 (SPL1) plays an opposite role to SP1 in peroxisomes. In contrast to sp1, loss-of-function of SPL1 led to reduced peroxisomal beta oxidation activity, and enhanced the physiological and growth defects of pex14 and pex13 mutants. Transient co-expression of SPL1 and SP1 promoted each other's destabilization. SPL1 reduced the ability of SP1 to induce PEX13 turnover, and it is the N-terminus of SP1 and SPL1 that determines whether the protein is able to promote PEX13 turnover. Finally, SPL1 showed prevalent targeting to mitochondria, but rather weak and partial localization to peroxisomes. Our data suggest that these two members of the same E3 protein family utilize distinct mechanisms to modulate peroxisome biogenesis, where SPL1 reduces the function of SP1. Plants and possibly other higher eukaryotes may employ this small family of E3 enzymes to differentially modulate the dynamics of several organelles essential to energy metabolism via the ubiquitin-proteasome system.

AB - GW2 is emerging as a key genetic determinant of grain weight in cereal crops; it has three homoeologs (TaGW2-A1, -B1 and -D1) in hexaploid common wheat (Triticum aestivum L.). Here, by analyzing the gene editing mutants that lack one (B1 or D1), two (B1 and D1) or all three (A1, B1 and D1) homoeologs of TaGW2, several insights are gained into the functions of TaGW2-B1 and -D1 in common wheat grain traits. First, both TaGW2-B1 and -D1 affect thousand-grain weight (TGW) by influencing grain width and length, but the effect conferred by TaGW2-B1 is stronger than that of TaGW2-D1. Second, there exists functional interaction between TaGW2 homoeologs because the TGW increase shown by a double mutant (lacking B1 and D1) was substantially larger than that of their single mutants. Third, both TaGW2-B1 and -D1 modulate cell number and length in the outer pericarp of developing grains, with TaGW2-B1 being more potent. Finally, TaGW2 homoeologs also affect grain protein content as this parameter was generally increased in the mutants, especially in the lines lacking two or three homoeologs. Consistent with this finding, two wheat end-use quality-related parameters, flour protein content and gluten strength, were considerably elevated in the mutants. Collectively, our data shed light on functional difference between and additive interaction of TaGW2 homoeologs in the genetic control of grain weight and protein content traits in common wheat, which may accelerate further research on this important gene and its application in wheat improvement. PMID- 29570881 TI - Lotus japonicus NOOT-BOP-COCH-LIKE1 is essential for nodule, nectary, leaf and flower development. AB - The NOOT-BOP-COCH-LIKE (NBCL) genes are orthologs of Arabidopsis thaliana BLADE ON-PETIOLE1/2. The NBCLs are developmental regulators essential for plant shaping, mainly through the regulation of organ boundaries, the promotion of lateral organ differentiation and the acquisition of organ identity. In addition to their roles in leaf, stipule and flower development, NBCLs are required for maintaining the identity of indeterminate nitrogen-fixing nodules with persistent meristems in legumes. In legumes forming determinate nodules, without persistent meristem, the roles of NBCL genes are not known. We thus investigated the role of Lotus japonicus NOOT-BOP-COCH-LIKE1 (LjNBCL1) in determinate nodule identity and studied its functions in aerial organ development using LORE1 insertional mutants and RNA interference-mediated silencing approaches. In Lotus, LjNBCL1 is involved in leaf patterning and participates in the regulation of axillary outgrowth. Wild type Lotus leaves are composed of five leaflets and possess a pair of nectaries at the leaf axil. Legumes such as pea and Medicago have a pair of stipules, rather than nectaries, at the base of their leaves. In Ljnbcl1, nectary development is abolished, demonstrating that nectaries and stipules share a common evolutionary origin. In addition, ectopic roots arising from nodule vascular meristems and reorganization of the nodule vascular bundle vessels were observed on Ljnbcl1 nodules. This demonstrates that NBCL functions are conserved in both indeterminate and determinate nodules through the maintenance of nodule vascular bundle identity. In contrast to its role in floral patterning described in other plants, LjNBCL1 appears essential for the development of both secondary inflorescence meristem and floral meristem. PMID- 29570882 TI - T2 , T1rho and TRAFF4 detect early regenerative changes in mouse ischemic skeletal muscle. AB - The identification of areas with regenerative potential in ischemic tissues would allow the targeting of treatments supporting tissue recovery. The regeneration process involves the activation of several cellular and molecular responses which could be detected using magnetic resonance imaging (MRI). However, to date, magnetic resonance (MR) relaxation parameters have received little attention in the diagnosis and follow-up of limb ischemia. The purpose of this study was to evaluate the feasibility of different MRI relaxation and diffusion tensor imaging parameters in the detection of areas showing early signs of regeneration in ischemic mouse skeletal muscles. T2 and T1rho relaxation time constants, together with TRAFFn , T1 and diffusion tensor imaging, were evaluated to differentiate areas of regeneration in a mouse hind limb ischemia model before and 0, 1, 4, 7, 14 and 30 days after ischemia. All the measured relaxation times were longer in the areas of early regeneration compared with normal muscle tissue. The relaxation times increased after ischemia in the ischemic muscles, reaching a maximum at 4-7 days after occlusion, coinciding with the appearance of early signs of regeneration. Fractional anisotropy decreased significantly (p < 0.05) on days 1-4, whereas mean diffusivity, lambda1 and lambda2 decreased later, starting at day 7 after ischemia compared with the pre-operational time point. The percentages of areas with different tissue morphologies were determined based on histological analysis of the ischemic muscle cross-sections, and correlations between the percentages obtained and different relaxation times were calculated. The highest correlation between relaxation times and histology was achieved with T2 , T1rho and TRAFF4 (R2 = 0.96, R2 = 0.92 and R2 = 0.84, respectively, p < 0.01). Early regenerative changes were visible using T2 , T1rho and TRAFF4 MR relaxation time constants in skeletal muscle after ischemia. These markers could potentially be used for the identification of targets for therapies supporting muscle regeneration after ischemic injury. PMID- 29570884 TI - A Stereochemically Driven Supramolecular Polymerisation. AB - Anthracyclines self-assemble in water into dimers. In the presence of sufficiently high salt (NaCl) concentrations, solutions of the antibiotic doxorubicin, but not those of the closely related molecules daunomycin and epirubicin, turn into gels barely compatible with the presence of small oligomers. The use of spectroscopic, scattering, imaging and computational techniques, allowed light to be shed on the self-assembly process that triggered doxorubicin gelification. A complex picture emerged, with doxorubicin molecules assembled into long, highly chiral, supramolecular aggregates made of hundreds of units, showing redshifted fluorescence spectra, very short fluorescence lifetimes and small-angle X-ray scattering profiles compatible with long cylinders. The involvement of specific chemical groups and the need for a specific stereochemistry of the monomers in the formation of a hydrogen-bond network to stabilise the supramolecular aggregates was supported by molecular dynamics calculations. A salt-induced, temperature-dependent, cooperative nucleation elongation supramolecular polymerisation of the doxorubicin molecules is deduced. PMID- 29570883 TI - Novel functions of the Arabidopsis transcription factor TCP5 in petal development and ethylene biosynthesis. AB - The flowers of most dicotyledons have petals that, together with the sepals, initially protect the reproductive organs. Later during development petals are required to open the flower and to attract pollinators. This diverse set of functions demands tight temporal and spatial regulation of petal development. We studied the functioning of the Arabidopsis thaliana TCP5-like transcription factors (TFs) in petals. Overexpression of TCP5 in petal epidermal cells results in smaller petals, whereas tcp5 tcp13 tcp17 triple knockout lines have wider petals with an increased surface area. Comprehensive expression studies revealed effects of TCP5-like TFs on the expression of genes related to the cell cycle, growth regulation and organ growth. Additionally, the ethylene biosynthesis genes 1-amino-cyclopropane-1-carboxylate (ACC) synthase 2 (ACS2) and ACC oxidase 2 (ACO2) and several ETHYLENE RESPONSE FACTORS (ERFs) are found to be differentially expressed in TCP5 mutant and overexpression lines. Chromatin immunoprecipitation-quantitative PCR showed direct binding of TCP5 to the ACS2 locus in vivo. Ethylene is known to influence cell elongation, and the petal phenotype of the tcp5 tcp13 tcp17 mutant could be complemented by treatment of the plants with an ethylene pathway inhibitor. Taken together, this reveals a novel role for TCP5-like TFs in the regulation of ethylene-mediated petal development and growth. PMID- 29570885 TI - Shoot phytochrome B modulates reactive oxygen species homeostasis in roots via abscisic acid signaling in Arabidopsis. AB - Underground roots normally reside in darkness. However, they are often exposed to ambient light that penetrates through cracks in the soil layers which can occur due to wind, heavy rain or temperature extremes. In response to light exposure, roots produce reactive oxygen species (ROS) which promote root growth. It is known that ROS-induced growth promotion facilitates rapid escape of the roots from non-natural light. Meanwhile, long-term exposure of the roots to light elicits a ROS burst, which causes oxidative damage to cellular components, necessitating that cellular levels of ROS should be tightly regulated in the roots. Here we demonstrate that the red/far-red light photoreceptor phytochrome B (phyB) stimulates the biosynthesis of abscisic acid (ABA) in the shoots, and notably the shoot-derived ABA signals induce a peroxidase-mediated ROS detoxification reaction in the roots. Accordingly, while ROS accumulate in the roots of the phyb mutant that exhibits reduced primary root growth in the light, such an accumulation of ROS did not occur in the dark-grown phyb roots that exhibited normal growth. These observations indicate that mobile shoot-to-root ABA signaling links shoot phyB-mediated light perception with root ROS homeostasis to help roots adapt to unfavorable light exposure. We propose that ABA-mediated shoot-to-root phyB signaling contributes to the synchronization of shoot and root growth for optimal propagation and performance in plants. PMID- 29570886 TI - Lysosomal LAMP1 immunoreactivity exists in both diffuse and neuritic amyloid plaques in the human hippocampus. AB - Lysosomal vesicles around neuritic plaques are thought to drive Alzheimer's disease by providing ideal microenvironments for generation of amyloid-beta. Although lysosomal vesicles are present at every amyloid plaque in mouse models of Alzheimer's disease, the number of amyloid plaques that contain lysosomal vesicles in the human brain remains unknown. This study aimed to quantify lysosomal vesicles at amyloid plaques in the human hippocampus. Lysosome associated membrane protein 1 (LAMP1)-positive vesicles accumulated in both diffuse (Abeta42-positive/AT8-negative) and neuritic (Abeta42-positive/AT8 positive) plaques in all regions were analysed. In contrast to mouse models of Alzheimer's disease, however, not all amyloid plaques accumulated LAMP1-positive lysosomal vesicles. Even at neuritic plaques, LAMP1 immunoreactivity was more abundant than phospho-tau (AT8). Further, lysosomal vesicles colocalised weakly with phospho-tau such that accumulation of lysosomal vesicles and phospho-tau appeared to be spatially distinct events that occurred within dystrophic neurites. This quantitative study shows that diffuse plaques, as well as neuritic plaques, contain LAMP1 immunoreactivity in the human hippocampus. PMID- 29570887 TI - Estimating B1+ in the breast at 7 T using a generic template. AB - Dynamic contrast-enhanced MRI is the workhorse of breast MRI, where the diagnosis of lesions is largely based on the enhancement curve shape. However, this curve shape is biased by RF transmit (B1+ ) field inhomogeneities. B1+ field information is required in order to correct these. The use of a generic, coil specific B1+ template is proposed and tested. Finite-difference time-domain simulations for B1+ were performed for healthy female volunteers with a wide range of breast anatomies. A generic B1+ template was constructed by averaging simulations based on four volunteers. Three-dimensional B1+ maps were acquired in 15 other volunteers. Root mean square error (RMSE) metrics were calculated between individual simulations and the template, and between individual measurements and the template. The agreement between the proposed template approach and a B1+ mapping method was compared against the agreement between acquisition and reacquisition using the same mapping protocol. RMSE values (% of nominal flip angle) comparing individual simulations with the template were in the range 2.00-4.01%, with mean 2.68%. RMSE values comparing individual measurements with the template were in the range8.1-16%, with mean 11.7%. The agreement between the proposed template approach and a B1+ mapping method was only slightly worse than the agreement between two consecutive acquisitions using the same mapping protocol in one volunteer: the range of agreement increased from +/-16% of the nominal angle for repeated measurement to +/-22% for the B1+ template. With local RF transmit coils, intersubject differences in B1+ fields of the breast are comparable to the accuracy of B1+ mapping methods, even at 7 T. Consequently, a single generic B1+ template suits subjects over a wide range of breast anatomies, eliminating the need for a time-consuming B1+ mapping protocol. PMID- 29570888 TI - Predictive value of unipolar and bipolar electrograms in idiopathic outflow tract ventricular arrhythmia mapping and ablation. AB - INTRODUCTION: Radiofrequency catheter ablation is an effective therapy for focal idiopathic outflow tract ventricular arrhythmia (OTVA). However, visual inspection of the unipolar electrogram (EGM) QS morphology is subjective with a poor specificity for predicting successful ablation sites. This study aims to evaluate the predictive value of unipolar and bipolar EGMs in OTVA mapping and ablation. METHODS AND RESULTS: Twenty-two patients scheduled for idiopathic OTVA ablation were prospectively enrolled. During the procedure, unipolar and bipolar EGMs were recorded simultaneously and visually inspected by the operator to identify their values for predicting arrhythmogenic sites. Quantitative features of the unipolar EGM including the ratio of amplitude of the first positive peak versus the nadir (R-ratio), the maximum descending slope (MaxSlope), and the time interval between the initial deflection point to the MaxSlope (D-Max) were calculated for each target site in offline analysis. EGMs from 100 sites were collected in 20 patients and analyzed. The bipolar reverse polarity characteristic was not as practical for identifying successful ablation site as the unipolar QS characteristic. Successful ablation sites demonstrated smaller R ratio and shorter D-Max than unsuccessful sites, but no significant difference in MaxSlope. A unipolar EGM-derived quantitative criterion provided significantly better specificity (0.70) than visual inspection (0.37) without compromising on the sensitivity (0.83 vs. 0.89). CONCLUSION: The bipolar reverse polarity characteristic was not a practical method for identifying target in idiopathic OTVA ablation. The unipolar EGM-derived quantitative criteria have better predictive performance than visual inspection of the QS characteristic and are likely to reduce unnecessary ablation sites. PMID- 29570889 TI - Enzyme-PISA: An Efficient Method for Preparing Well-Defined Polymer Nano-Objects under Mild Conditions. AB - Enzyme catalysis is a mild, efficient, and selective technique that has many applications in organic synthesis as well as polymer synthesis. Here, a novel enzyme-catalysis-induced reversible addition-fragmentation chain transfer (RAFT) mediated dispersion polymerization for preparing AB diblock copolymer nano objects with complex morphologies at room temperature is described. Taking advantage of the room-temperature feature, it is shown that pure, worm-like polymer nano-objects can be readily prepared by just monitoring the viscosity. Moreover, it is demonstrated that inorganic nanoparticles and proteins can be loaded in situ into vesicles by this method. Finally, a novel oxygen-tolerant RAFT-mediated dispersion polymerization initiated by enzyme cascade reaction that can be carried out in open vessels is developed. The enzyme-initiated RAFT dispersion polymerization provides a facile platform for the synthesis of various functional polymer nano-objects under mild conditions. PMID- 29570890 TI - Threats and Supports to Female Students' Math Beliefs and Achievement. AB - This study examines how student perceptions of teacher practices contribute to female high school students' math beliefs and achievement. Guided by the expectancy-value framework, we hypothesized that students' motivation beliefs and achievement outcomes in mathematics are fostered by teachers' emphasis on the relevance of mathematics and constrained by gender-based differential treatment. To examine these questions, structural equation modeling was applied to a longitudinal panel of 518 female students from the Maryland Adolescent Development in Context Study. While controlling for prior achievement and race, gendered differential treatment was negatively associated with math beliefs and achievement, whereas relevant math instruction was positively associated with these outcomes. These findings suggest inroads that may foster positive math motivational beliefs and achievement among young women. PMID- 29570892 TI - A Temperature-Controlled, Conductive PANI@CNFs/MEO2 MA/PEGMA Hydrogel for Flexible Temperature Sensors. AB - Electrically conductive, yet stimuli-responsive hydrogels are highly desirable for many technological applications. However, the discontinuous conductivity of hydrogels during the response process has become a bottleneck that limits their application. To overcome this constraint, a linearly tunable, electrically conductive hydrogel is prepared using in-situ polymerized polyaniline (PANI) on a CNFs/MEO2 MA/PEGMA hydrogel (PANI@CMP hydrogel) substrate. The PANI@CMP hydrogel exhibits temperature-tunable electrical conductivity due to the liner relationship between thermosensitivity and temperature of the CMP hydrogel substrate. Furthermore, the stiffness and elasticity of the resultant hydrogel after PANI introduction is enhanced via physical interactions, and the compression load is improved by 42%. A highly sensitive temperature sensor is therefore fabricated with PANI@CMP hydrogel as the flexible induction element, and this sensor achieves temperature monitoring from 20 to 60 degrees C. This new temperature-controllable conductive hydrogel has excellent mechanical properties, showing great potential for applications in flexible smart sensors, conductive fillers, and medical devices. PMID- 29570891 TI - Poly ADP-ribose polymerase-1 as a potential therapeutic target in Merkel cell carcinoma. AB - BACKGROUND: Patients with metastatic Merkel cell carcinoma are treated similarly to small cell lung cancer (SCLC). Poly ADP-ribose polymerase-1 (PARP1) is overexpressed in SCLC and response to PARP inhibitors have been reported in patients with SCLC. Our study explores PARP as a therapeutic target in Merkel cell carcinoma. METHODS: We evaluated PARP1 expression and Merkel cell polyomavirus (MCPyV) in 19 patients with Merkel cell carcinoma. Target exome sequencing was performed in 14 samples. Sensitivity to olaparib was tested in 4 Merkel cell carcinoma cell lines. RESULTS: Most Merkel cell carcinomas (74%) express PARP1 at high levels. Mutations in DNA-damage repair genes were identified in 9 samples (64%), occurred exclusively in head neck primaries, and correlated with TP53/RB1 mutations. The TP53/RB1 mutations were more frequent in MCPyV-negative tumors. Sensitivity to olaparib was seen in the Merkel cell carcinoma line with highest PARP1 expression. CONCLUSION: Based on PARP1 overexpression, DNA-damage repair gene mutations, platinum sensitivity, and activity of olaparib in a Merkel cell carcinoma line, clinical trials with PARP inhibitors are warranted in Merkel cell carcinoma. PMID- 29570893 TI - Comparison of dispensed medications and forensic-toxicological findings to assess pharmacotherapy in the Swedish population 2006 to 2013. AB - PURPOSE: To investigate person-level agreement between medication exposure as predicted using the PRE2DUP (a prescription-based design to estimate continuous drug use) method and postmortem toxicological findings, in the Swedish population during the years 2006 to 2013. METHODS: Using the Swedish National Board of Forensic Medicine's toxicology database and the Swedish National Board of Health and Welfare's registries on causes of death, dispensed medications, and in patient care, forensic-toxicological findings were compared with prescription based estimates of drug use for 27 medications. We modeled expected drug-use periods with the PRE2DUP using an algorithm of demonstrated high validity that evaluates personal drug-purchasing patterns with consideration to possible stockpiling of drugs and package information. Excluding criteria included self inflicted death and recent in-patient care. RESULTS: In data from 18 627 performed autopsies, as well as 10 160 instances of dispensed drug use, the agreement between PRE2DUP drug-use periods and forensic toxicology was, overall, moderate (Cohen's kappa: 0.56 [95% confidence interval {CI}: 0.55-0.57]) with a positive predictive value, or predicted adherence rate, of 46.0%. The group-level predicted adherence and agreement were highest for antidepressants, at 71.0% (Cohen's kappa: 0.74 [CI: 0.73-0.76]), and lowest for cardiovascular drugs, at 21.5% (Cohen's kappa: 0.33 [CI: 0.31-0.36]). Predicted recreational use (negative predictive value) was low for all investigated drugs (0.0%-1.4%). The biological half-life explained 29% (P = 0.003) of the variability of the false-positive rate. CONCLUSIONS: Measured agreement between PRE2DUP-based drug-use estimates and forensic-toxicological findings is dependent upon a number of factors, including true continuous drug use and postmortem detectability of the investigated drugs, as well as the occurrence of unconventional dosing and true non-adherence. PMID- 29570894 TI - Prophylactic pulmonary vein isolation during isthmus ablation for atrial flutter: Three-year outcomes of the PREVENT AF I study. AB - INTRODUCTION: The PREVENT AF I study demonstrated that prophylactic pulmonary vein isolation (PVI) in patients with pure typical atrial flutter (AFL) resulted in substantial reduction of new-onset atrial fibrillation (AF) during 1-year follow-up as assessed by continuous implantable cardiac monitor (ICM). The objective of this study was to assess 3-year outcomes. METHODS AND RESULTS: Fifty patients with documented AFL were randomized to either cavotricuspid isthmus (CTI) ablation alone (n = 25) or CTI with concomitant PVI (n = 25). The primary endpoint of the study was the occurrence of any atrial tachyarrhythmia with the monthly burden exceeding 0.5% on the ICM. At the end of 3 years, freedom from any atrial tachyarrhythmia was 48% (95% confidence interval [CI]: 32-72%) in the CTI plus PVI group as compared to 20% (95% CI: 9-44%) in the CTI-only group (P = 0.01). Freedom from redo procedures was also higher: 92% (95% CI: 82-100%) versus 68% (95% CI: 52-89%), respectively (P = 0.027). The 3-year AF burden favored the combined ablation group: 6.2% versus 16.8% (P = 0.03). In the CTI-only group, 12 (48%) patients were hospitalized compared to 4 (16%) in the PVI + CTI group (P = 0.03). Two patients in the CTI-only group developed stroke with no serious adverse events in the PVI + CTI group. CONCLUSION: Prophylactic PVI in patients with only typical AFL resulted in a significant reduction of new-onset AF and burden during long-term follow-up as assessed by ICM, with consequent reduction in hospitalizations and need to perform repeat ablation for AF. PMID- 29570896 TI - Friendless Adolescents: Do Perceptions of Social Threat Account for Their Internalizing Difficulties and Continued Friendlessness? AB - Adolescents who lack friends at school are at risk of internalizing difficulties. This study examined a social-cognitive mechanism underlying friendlessness and internalizing difficulties (i.e., depressive symptoms, social anxiety, low self esteem). We tested whether perceived social threat (i.e., peer victimization, sense of unsafety, and peer misconduct) mediates the association between friendlessness and increased internalizing difficulties across middle school. Latent variable structural equation modeling was used to test the model among an ethnically diverse sample of 5,991 (52% female) adolescents. The results demonstrate that friendless sixth-grade students perceived their school environment as more threatening by seventh grade, which in turn, increased internalizing difficulties from sixth to eighth grade. Perceptions of threat also predicted friendlessness at the end of middle school. PMID- 29570895 TI - Repeatability, reproducibility, and accuracy of quantitative mri of the breast in the community radiology setting. AB - BACKGROUND: Quantitative diffusion-weighted MRI (DW-MRI) and dynamic contrast enhanced MRI (DCE-MRI) have the potential to impact patient care by providing noninvasive biological information in breast cancer. PURPOSE/HYPOTHESIS: To quantify the repeatability, reproducibility, and accuracy of apparent diffusion coefficient (ADC) and T1 -mapping of the breast in community radiology practices. STUDY TYPE: Prospective. SUBJECTS/PHANTOM: Ice-water DW-MRI and T1 gel phantoms were used to assess accuracy. Normal subjects (n = 3) and phantoms across three sites (one academic, two community) were used to assess reproducibility. Test retest analysis at one site in normal subjects (n = 12) was used to assess repeatability. FIELD STRENGTH/SEQUENCE: 3T Siemens Skyra MRI quantitative DW-MRI and T1 -mapping. ASSESSMENT: Quantitative DW-MRI and T1 -mapping parametric maps of phantoms and fibroglandular and adipose tissue of the breast. STATISTICAL TESTS: Average values of breast tissue were quantified and Bland-Altman analysis was performed to assess the repeatability of the MRI techniques, while the Friedman test assessed reproducibility. RESULTS: ADC measurements were reproducible across sites, with an average difference of 1.6% in an ice-water phantom and 7.0% in breast fibroglandular tissue. T1 measurements in gel phantoms had an average difference of 2.8% across three sites, whereas breast fibroglandular and adipose tissue had 8.4% and 7.5% average differences, respectively. In the repeatability study, we found no bias between first and second scanning sessions (P = 0.1). The difference between repeated measurements was independent of the mean for each MRI metric (P = 0.156, P = 0.862, P = 0.197 for ADC, T1 of fibroglandular tissue, and T1 of adipose tissue, respectively). DATA CONCLUSION: Community radiology practices can perform repeatable, reproducible, and accurate quantitative T1 -mapping and DW-MRI. This has the potential to dramatically expand the number of sites that can participate in multisite clinical trials and increase clinical translation of quantitative MRI techniques for cancer response assessment.

PMID- 29570897 TI - Methodological challenges when evaluating potential off-label prescribing of drugs using electronic health care databases: A case study of dabigatran etexilate in Europe. AB - PURPOSE: To report and discuss estimated prevalence of potential off-label use and associated methodological challenges using a case study of dabigatran. METHODS: Observational, cross-sectional study using 3 databases with different types of clinical information available: Cegedim Strategic Data Longitudinal Patient Database (CSD-LPD), France (cardiologist panel, n = 1706; general practitioner panel, n = 2813; primary care data); National Health Databases, Denmark (n = 28 619; hospital episodes and dispensed ambulatory medications); and Clinical Practice Research Datalink (CPRD), UK (linkable to Hospital Episode Statistics [HES], n = 2150; not linkable, n = 1285; primary care data plus hospital data for HES-linkable patients). STUDY PERIOD: August 2011 to August 2015. Two definitions were used to estimate potential off-label use: a broad definition of on-label prescribing using codes for disease indication (eg, atrial fibrillation [AF]), and a restrictive definition excluding patients with conditions for which dabigatran is not indicated (eg, valvular AF). RESULTS: Prevalence estimates under the broad definition ranged from 5.7% (CPRD-HES) to 34.0% (CSD-LPD) and, under the restrictive definition, from 17.4% (CPRD-HES) to 44.1% (CSD-LPD). For the majority of potential off-label users, no diagnosis potentially related to anticoagulant use was identified. Key methodological challenges were the limited availability of detailed clinical information, likely leading to overestimation of off-label use, and differences in the information available, which may explain the disparate prevalence estimates across data sources. CONCLUSIONS: Estimates of potential off-label use should be interpreted cautiously due to limitations in available information. In this context, CPRD HES linkable estimates are likely to be the most accurate. PMID- 29570898 TI - Novel connectivity map normalization procedure for improved quantitative investigation of structural thalamic connectivity in temporal lobe epilepsy patients. AB - BACKGROUND: Connectivity studies targeting the thalamus have revealed patterns of atrophy and deafferentiation in temporal lobe epilepsy (TLE). The thalamus can be parcellated using probabilistic tractography to demonstrate regions of cortical connectivity; however, sensitivity to smaller or less connected regions is low. PURPOSE/HYPOTHESIS: To investigate thalamic structural connectivity in a wider range of cortical and limbic structures in TLE patients using a novel connectivity map normalization procedure. STUDY TYPE: Retrospective. POPULATION/SUBJECTS: Patients (N = 23) with medication-resistant TLE and 34 healthy age-matched controls. FIELD STRENGTH/SEQUENCE: For T1 and diffusion weighting a spoiled gradient sequence was used (41 gradient directions [b = 1000]). For T2 mapping balanced steady-state free precession was used. Images were acquired at 3T. ASSESSMENT: Probabilistic tractography and a novel normalization procedure allowed comparison of groups with respect to thalamic connected volume, quantitative MRI, and diffusion tensor imaging (DTI) metrics. STATISTICAL TESTS: Independent samples t-test, Cohen's d, and Mann-Whitney tests. RESULTS: Following normalization, significant differences in thalamic connected volumes were found in left TLE vs. controls bilaterally within the posterior parahippocampal gyrus (L: P = 0.007, confidence interval [CI]: [173.306,1044.41], effect size [ES] = 1.072; R: P = 0.017, CI: [98.677,947.653], ES = 0.945), and contralaterally in the anterior temporal neocortex (P = 0.01, CI: (-2348.09, 333.719), ES = -1.021). This procedure revealed differences in thalamic connected volumes, where previously published procedures could not, and provided a basis for exploratory analysis of quantitative MRI and DTI metrics. DATA CONCLUSION: The novel connectivity map normalization scheme proposed here successfully allowed comparison between a wider range of cortical and limbic structures. Multiple volumetric and quantitative MRI and DTI-related differences between TLE patients and controls were revealed following normalization. With validation from a larger cohort, thalamo-temporal connection aberrancies may become useful biomarkers of disease states and probabilistic tractography as a procedure for identification of thalamic targets in modulatory therapies for TLE.

AB - Although adolescents experience an array of out-of-school time (OST) settings, research has primarily focused on these settings in isolation. This study examined time in four OST settings (unsupervised time with peers, paid employment, sports, and nonsports organized activities) in relation to adolescent functioning at age 15 and the end of high school. Individual fixed effects analyses provided a more rigorous control of selection into OST activities by controlling for time-invariant observable and unobservable characteristics. More unsupervised time with peers predicted increases in risky and externalizing behaviors, whereas increases in paid employment predicted gains in work orientation and self-identity. Time in organized sports was associated with increased positive self-identity, highlighting the value of expanding consideration of multiple OST contexts and selection effects. PMID- 29570900 TI - Temporal trends in safety and complication rates of catheter ablation for atrial fibrillation. AB - INTRODUCTION: Atrial fibrillation (AF) ablation is increasingly common, but is associated with potential major complications. Technology, experience, and protocols have evolved significantly in recent times, and may have impacted procedural safety. We sought to compare AF ablation safety profiles, including complication rates and fluoroscopy times in a "modern" versus "historical" cohort. METHODS AND RESULTS: We evaluated consecutive patients undergoing AF ablation from a modern cohort (MC) from 2014 to 2015 and a historic cohort (HC) from 2009 to 2011 for complications. Major complications were categorized according to Heart Rhythm Society guidelines. We included 1,425 patients, 726 in the HC and 699 in the MC. The MC was older, had more OSA and less valvular AF. Fifty-two (3.5%) procedures suffered major complications across the cohorts, with significantly fewer in the MC (5.0% vs. 2.3%, P = 0.007). The largest reductions were seen in vascular, hemorrhagic, ischemic stroke, and perforation/tamponade related complications. Periprocedural antiplatelets drugs (aHR 2.1 [95 CI 1.1-3.9], P = 0.02) and force-sensing catheters (aHR 0.4 [95 CI 0.2-0.9], P = 0.03) were independently related to major complication rates. Direct oral anticoagulants and uninterrupted anticoagulation were not associated with complications. There was a decrease in both fluoroscopy (-17.4 minutes [95 CI 19.2-15.6], P < 0.0001) and radiofrequency ablation times (-561 seconds [95CI 750 to -371], P < 0.0001). CONCLUSIONS: The safety profile of AF ablation has improved significantly in less than a decade. PMID- 29570901 TI - An interesting case of intra-Hisian Wenkebach with left bundle branch block. PMID- 29570902 TI - A transcriptomics study of differentiated C2C12 myoblasts identified novel functional responses to 17beta-estradiol. AB - Previous studies of the role of 17beta-estradiol (E2) in myoblast differentiation have produced conflicting data. Therefore, this work aimed to determine the role of E2 on myoblast differentiation and specific myofiber formation. Murine C2C12 myoblasts were cultured in proliferation medium or differentiation medium/10 nM E2. The role of E2 on specific myosin heavy chain (MyHC) or estrogen receptor (ER) expression was examined using real-time quantitative RT-PCR (RT-qPCR). Transcriptome studies of E2 on myoblast differentiation were accomplished by microarray analyses. The expression levels of candidate genes from microarrays and four and a half LIM domains 1 (Fhl1) were detected with RT-qPCR. E2 in differentiation medium significantly up-regulated MyHC I expression, but exerted the opposite effects on MyHC II a, MyHC II b, and MyHC II d. Both ER-alpha and ER beta were decreased in differentiated C2C12, and E2 partially restored ER-beta expression. Sixty-two up-regulated and 116 down-regulated genes treated by E2 were identified, and RT-qPCR validation results showed seven cytoskeletal genes (Myh8, Cenpe, Jak3, Obscn, Ldb3, Mybpc2, Col4a3bp), three genes related to ion channels (Kcnq1, Lrrc26, P2rx3) and Fhl1 transcript 2 were associated with the effects of E2 on myoblast differentiation. These findings suggested E2 helped slow type MyH I fiber formation and impeded fast 2A, 2X/D, and 2B fiber formation. PMID- 29570904 TI - Toward a New Understanding of Ethnic-Racial Settings for Ethnic-Racial Identity Development. AB - The purpose of this conceptual article is to advance theory and research on one critical aspect of the context of ethnic-racial identity (ERI) development: ethnic-racial settings, or the objective and subjective nature of group representation within an individual's context. We present a new conceptual framework that consists of four dimensions: (1) perspective (that settings can be understood in both objective and subjective terms); (2) differentiation (how groups are defined in a setting); (3) heterogeneity (the range of groups in a setting); and (4) proximity (the distance between the individual and the setting). Clarifying this complexity is crucial for advancing a more coherent understanding of how ethnic-racial settings are related to ERI development.

AB - Gastric cancer (GC) is one of the most common malignancies worldwide. TGF-beta1 induces the epithelial-mesenchymal transition (EMT) in GC, mainly through Smad dependent pathways. Nevertheless, few studies have focused on the activation of non-canonical transduction pathways. TRPC, Ca2+ entry channels, are ubiquitously expressed in various cell types and are involved in many cellular functions. However, their roles in GC are not well elucidated. This study aimed to determine whether TRPC participates in the TGF-beta1-induced EMT of GC and to investigate the potential mechanisms. Immunofluorescence staining was performed to examine the distribution and expression of TRPCs and EMT-related proteins in SGC-7901 cells incubated with or without TGF-beta1. The expression of TRPC1/3/6 and EMT related molecules, including E-cadherin, vimentin, and alpha-SMA, was detected by qRT-PCR and Western blotting. Additionally, the underlying mechanism was determined by treating cells with pharmacological inhibitors and examining the levels of proteins involved in the main signaling cascades using Western blotting. TRPC1/3/6 were expressed at high levels in SGC-7901 cells. Following TGF-beta1 stimulation, the expression of vimentin, alpha-SMA, and TRPC1/3/6 increased and E-cadherin expression decreased, accompanied by activation of the Ras/Raf1/ERK1/2 signaling pathway. Notably, activation of the Ras/Raf1/ERK1/2 signaling cascade was suppressed by SKF96365 and 2-APB. Both TRPC and ERK inhibitors mitigated EMT progression. Based on these results, TRPC1/3/6 inhibition attenuated the TGF-beta1-induced EMT in GC by suppressing Ras/Raf1/ERK signal transduction. PMID- 29570905 TI - Development and validation of oral health-related quality of life measure in oral submucous fibrosis. AB - OBJECTIVE: The aim of this study was to develop and assess the validity and reliability of disease-specific oral health-related quality of life (OHRQoL) instrument for oral submucous fibrosis (OSF). MATERIALS AND METHODS: Items for the OHRQoL-OSF were generated from personal interviews and focus group discussions, the existing questionnaires, reviews of literature and inputs from expert's panel. Item reduction was performed by clinical impact method followed by pretesting of the developed questionnaire. The validity and reliability of the instrument were then examined. RESULTS: Forty-five items were generated from qualitative data and item pooling from various sources. After item reduction, 17 items were finalized with four domain-structure having Eigenvalues greater than 1. OHRQoL-OSF was shown to be valid in distinguishing patients with varying degrees of OSF severity. For the concurrent validity, the observed impact of OSF based on OHRQoL-OSF significantly correlated with Oral Health Impact Profile and global self-ratings of oral health and overall well-being. OHRQoL-OSF and all its domains demonstrated good internal consistency reliability with Cronbach's alpha ?0.7 and excellent test-retest reliability (ICC = 0.96). CONCLUSION: The first disease-specific OHRQoL-OSF instrument appeared to be highly reliable and valid measure for assessing impact of OSF on life quality.

PMID- 29570907 TI - Randomized pilot study on probiotic effects on recurrent candidiasis in oral lichen planus patients. AB - : Some patients with oral lichen planus (OLP) experience recurrent oral candidiasis(OC). Probiotic bacteria have shown to reduce the oral Candida count in vivo. OBJECTIVE: To study whether probiotic intervention reduces recurrent OC in patients with OLP. MATERIAL AND METHODS: Twenty-two patients with symptomatic OLP were enrolled in the double-blinded, randomized, placebo-controlled intervention study. Lozenges containing Lactobacilli reuteri (DSM 17938 and ATCC PTA 5289) or placebo were dissolved intra-orally three times daily for 16 weeks, after which patients were followed up for 36 weeks. Mucosal symptoms, VAS pain, OLP severity score, plaque index (PI) and gingival index (GI), Candida count/carriage, and OC and/or need for symptomatic treatment were registered. Statistical significance was set at p < .05. RESULTS: No difference was observed between the groups during the intervention or follow-up in terms of recurrent OC (p = .966) or need for symptomatic treatment (p = 1.000). There was no difference in terms of Candida count (p = .96) or carriage over time (p = .511). GI decreased in the probiotic group and increased in the placebo group (p = .046). OLP severity score decreased in both groups during the study period (p = .039). Across the entire study period, the placebo group had higher VAS pain score (p = .037). CONCLUSIONS: Probiotic intervention did not reduce recurrent OC or Candida count/carriage, but the study experienced recruitment problems, which may have influenced results.

PMID- 29570909 TI - Effect of prolonged hospitalization for threatened preterm labor on maternal and fetal vitamin D levels. AB - AIM: We aimed to evaluate the effect of prolonged hospitalization for threatened preterm labor (TPL) on maternal and fetal vitamin D status. METHODS: This was a retrospective cohort study, spanning 4 years, including 18 women with TPL and 36 women with normal pregnancy who received prenatal care for a singleton pregnancy at our center. TPL cases were women who were admitted to our hospital after the second trimester test for at least 28 days, during which time the third trimester test was also performed. Controls were randomly sampled from women matched for age as well as the season during which the third trimester test was performed. Serum 25-hydroxyvitamin D (25(OH)D) concentration in maternal blood was compared between the two groups at second trimester, third trimester and in the umbilical cord blood at delivery. RESULTS: The mean +/- SD of maternal serum 25(OH)D concentration in the TPL group (14.0 +/- 3.0 ng/mL) was significantly lower than that in the control group (17.8 +/- 5.9 ng/mL) (P < 0.01) in the third trimester, although there was no significant difference in the second trimester (P = 0.30). There was a significant reduction (P < 0.01) in the maternal serum 25(OH)D from the second to third trimester in the TPL group, compared to the control group (P = 0.60). There was no significant difference between the two groups in umbilical cord blood 25(OH)D concentrations at delivery (P = 0.41). CONCLUSION: Prolonged hospitalization for TPL reduced the maternal vitamin D status but did not influence the neonatal status at delivery. PMID- 29570910 TI - Adult brain activation during visual learning and memory tasks. An experimental approach to translational neuroscience. AB - RATIONALE, AIMS, AND OBJECTIVES: Human brain connectome is a new and rapidly developing field in neuroscience. The pattern of structural and functional connectivity in the brain is not fixed but is continuously changing in response to experiences. Exploring these phenomena opens a powerful arsenal of analyses and computational approaches that could provide important new insights into clinical and cognitive neuroscience. The aim of the present study was to investigate the activations of adult brain cortical areas during a memory task performance by using functional MRI with a specific focus on gender differences. METHODS: Twenty-nine right-handed subjects (15 men and 14 women) were scanned. The memory paradigm consisted of 4 consecutive sets of "on" and "off" blocks with a total duration of 4 minutes. The subjects were first presented with 4 pictures (fixation F-part) of the same theme-landscapes, portraits, anatomical images of internal organs, and geometric figures denoted by specific mismatching nouns (seasons, personal names, internal organs, and figures), followed by 3 of the presented pictures and questions for memory evaluation (recall R-part). For the active conditions, the participants were instructed to read the statements carefully and answer with a button press. RESULTS: We found reliable occipital and temporal signal responses across the block design contrasts with statistical significant differences within the groups in both genders. Statistical significance in brain cortical activation was not found between men and women. CONCLUSION: The results highlighted several detailed distinctions between the genders and potential future directions in brain activation studies as part of the multidisciplinary approach in translational neuroscience. PMID- 29570911 TI - Methodological Challenges to collecting Clinical and Economic Outcome Data: Lessons from the Pilot Dialysis Outcomes India Study. AB - INTRODUCTION: Contemporary data on clinical and economic outcomes and quality of care amongst dialysis patients in India are not available. This pilot prospective study evaluated the feasibility of data collection and follow up within routine dialysis practice to inform setting up a dialysis registry. METHODS: An electronic instrument was developed to collect information on clinical and socio demographic characteristics, outcome and out-of-pocket expenditure on incident patients commencing haemodialysis (HD) at two centres. Dialysis unit staff were trained in collecting and entering information on an electronic case record form. Patients were followed up at 1, 3, 6, 9 and 12 months to ascertain outcomes and treatment related costs. RESULTS: A total of 119 patients (37 females, age 47.5+17.2 years) were enrolled. After 1 year, 38 (32%) patients were continuing on HD; 35 (29%) had died, 30 (25%) underwent a kidney transplant, and 16 (13%) had stopped dialysis. We noted a high prevalence of catastrophic health expenditure. Data collection was facilitated by appointing a designated staff member who received an incentive. Collection of financial information, clinical course for patients transferring out of the primary unit and the cause of death, when it occurred out of hospital was challenging. CONCLUSIONS: Prospective data collection of incident dialysis patients was feasible but is resource-intensive. High out-of-pocket costs force some patients to stop dialysis and can generate a sense of despair. Poor patient experiences and suspicion over the use of such data adversely affects collection of important clinical and health economic data. PMID- 29570912 TI - A case of severe soft tissue infection due to Streptococcus tigurinus diagnosed by necropsy in which genomic analysis was useful for clarifying its pathogenicity. AB - Post-mortem detection of pathogenetic microorganisms in severe infectious death is significantly important for diagnosing the cause of death as well as for public health. However, it is difficult to recognize whether a microorganism detected from post-mortem materials is truly pathogenic or not. We report a case of severe soft tissue infection due to Streptococcus oralis subsp. tigurinus (S. tigurinus), a recently reported species, in which whole-genome analysis was performed to clarify its pathogenicity. A 46-year-old woman had died with symptoms of a severe infectious disease. A post-mortem examination was performed by a medical examiner. The external findings suggested a soft tissue infection; subsequently, pathological specimens sampled by necropsy revealed findings compatible with necrotizing fasciitis. In the post-mortem bacterial test, S. tigurinus was detected from the localized autopsy sample. Whole-genome sequencing was performed to analyze its pathogenicity and detected a strain of S. tigurinus with genetic determinants that were specific and unique to its highly virulent strains as a result of gene annotation. Utilizing various technologies, such as whole-genome sequencing, may be a powerful tool for diagnosing the cause of infectious death accurately and safely. PMID- 29570913 TI - Children with cochlear implants in infancy: predictors of early vocabulary. AB - BACKGROUND: Language outcomes for children with cochlear implants (CIs) vary widely, even for those implanted before 2 years of age. Identifying the main influencing factors that account for some of the variability is important in order to provide information to guide appropriate clinical and intervention services for young children with CIs. However, there is limited research focusing on the predictors of early vocabulary development for children implanted in infancy. AIMS: To identify significant predictors of vocabulary (12-15 months post-implant) for a sample of 33 children with CIs, the majority implanted between 6 and 10 months of age, drawing on predictors of vocabulary reported for children with normal hearing. Of particular interest was the impact of pre implant development and use of gestures. METHODS & PROCEDURES: Children with severe to profound hearing loss, and no other known disabilities, were recruited from CI clinics in Australia before receiving their CIs. Subscales from the Bayley Scales-III (receptive and expressive communication, gross and fine motor, and cognition) were used to assess their development at that time. Using the Macarthur-Bates Communicative Development Inventory (Words and Gestures) we documented the children's (1) use of gestures at six data-collection times 3 months apart; and (2) vocabulary at the last three time points. Time since implant and time to consistent use of the CIs were also included as potential predictors. Data were analysed using generalized linear models, assuming a negative binomial response with a log-link function. Stepwise variables selection was followed to retain a smaller number of the covariates. OUTCOMES & RESULTS: A year after implantation, the significant predictors identified for vocabulary were pre-implant receptive communication and early gesture use. Together with fine motor and cognitive skills, these two variables were also significant predictors of vocabulary 3 months later. With maternal education entered into the models, higher vocabulary scores were significantly associated with higher maternal education 12 months post-implantation, but not 15 months. CONCLUSIONS & IMPLICATIONS: Pre-implant abilities are important in explaining some variability in the early vocabulary of infants with CIs, together with their use of early gestures post-implantation. That is, having a non-verbal means to express a concept can assist in their development of oral vocabulary. Identifying strategies to help develop fine motor skills for infants with CIs, and encouraging their use of gestures to communicate their needs/intentions, are likely to be of benefit. PMID- 29570914 TI - Voriconazole concentration is inversely correlated with corticosteroid usage in immunocompromised patients. AB - BACKGROUND: Voriconazole (VRCZ) is a broad-spectrum antifungal agent that can be administered both orally and intravenously. A high level of intra- and interindividual variability in serum drug therapeutic concentrations has been reported. We analyzed the influence of corticosteroid use on serum VRCZ concentration by assessing the correlation between corticosteroid dose and VRCZ trough level. METHODS: Immunocompromised patients treated with VRCZ with or without corticosteroid use from June 2010 to March 2017 (6 years and 8 months) were reviewed in our institute. VRCZ and the corticosteroids were administered orally or intravenously. Corticosteroid treatment was considered as "concurrent" only if it was administered within 3 days before or after the initiation of VRCZ. All corticosteroids were converted to a prednisolone-based dosage according to their anti-inflammatory effect (relative glucocorticoid activity). VRCZ concentration was measured at the trough point on the day of steady state. RESULTS: A total of 85 samples were obtained from 38 patients. The medical records of 23 women and 15 men, with a median age of 61 years (range: 35-86), were reviewed. Twenty-one patients (55.3%, 21/38) received chemotherapy, and 28 (73.7%, 28/38) received corticosteroid therapy. The average and median daily doses of corticosteroids were 59.2 and 89.8 mg, respectively (range: 0.714-377). VRCZ concentration was inversely correlated with corticosteroid dose (r = -.26). The VRCZ concentration was significantly decreased in the corticosteroid user compared to nonuser (P = .013). We evaluated the association of VRCZ concentration and corticosteroid dose in 3 patients among our cohorts for whom more than 5 points of data were available. Intraindividual analysis revealed the trough level of VRCZ concentration decreased as the corticosteroid dose increased. The patients' underlying diseases were hematological diseases (n = 25) and immunological diseases (n = 13). Among accrual patients, no patients were undergoing stem cell transplantation, and no patients were treated with known confounders such as calcineurin inhibitors or phenytoin. CONCLUSIONS: VRCZ might be metabolized by an enzyme induced by corticosteroid treatment; therefore, intraindividual variation in VRCZ metabolism should be considered prior to concurrent treatment, especially for patients with hematological malignancies treated with corticosteroids. PMID- 29570915 TI - Ischemia-modified albumin in preterm infants born to mothers with pre-eclampsia. AB - BACKGROUND: Pre-eclampsia (PE) carries an increased risk for maternal and/or fetal mortality or serious morbidity. PE is associated with ischemia and increased oxidative stress in the placenta, which may lead to modification of plasma albumin to ischemia-modified albumin (IMA). The aim of this study was to investigate IMA and hematological parameters in mothers and in premature infants in normal and in pre-eclamptic pregnancies. METHODS: Twenty-five pregnant women with PE and their premature newborns were categorized as the PE group, and 25 normotensive pregnant women and their premature newborns as the control group. Preterm infants are classified as small for gestational age (SGA) or non-SGA according to the Fenton preterm growth chart. Serum IMA, complete blood count (CBC), liver function tests (LFT), renal function tests (RFT), albumin, and C reactive protein were measured in the mothers immediately before birth, and in the cord blood and serum of the newborns at 6 and 24 h after birth. Clinical and demographic data were recorded for both groups. RESULTS: While IMA, LFT and RFT were significantly increased in the PE group compared with the control group, albumin and CBC were significantly lower in the PE group. A total of 40% of PE newborns were SGA, 30% of whom had severe SGA (birthweight <3rd percentile). Cord IMA was significantly increased in all preterm neonates in the PE group compared with the control group. No mothers or neonates died. CONCLUSION: Serum IMA in addition to the prevalence of SGA were significantly increased in the PE group. Cord blood IMA, therefore, might be a predictive biomarker for SGA in PE pregnancies. PMID- 29570916 TI - Factors affecting propofol dosage for sedation in pediatric oncology. AB - BACKGROUND: There is limited reference data for determining the appropriate dose of propofol for individual patients. Therefore, we investigated the factors affecting propofol dosage for pediatric patients undergoing sedation for computed tomography (CT) simulation. METHODS: We retrospectively analyzed the electronic medical records of pediatric patients who underwent CT simulation for proton therapy following a cancer diagnosis at the National Cancer Center (Korea) between 1 May 2012 and 30 April 2016. We evaluated the following factors, which reflect comorbidities or chronic illness in pediatric oncology patients: age, tumor lesion, preterm birth, American Society of Anesthesiologists (ASA) classification, pre-sedation temperature, history of propofol use, nothing by mouth time, chemotherapy history, pre-sedation laboratory findings, regular medication (opioids, anticonvulsants), and use of diuretics. A regression analysis was performed and P < 0.05 was considered statistically significant. RESULTS: Electronic medical records of 84 pediatric cancer patients were used in the analysis. Patients in ASA classes 1-2 required approximately 43% more propofol than patients in classes 3-4 (exp(beta), 1.43; 95%CI: 1.21-1.69, P < 0.001). CONCLUSION: American Society of Anesthesiologists class 3 or 4 is an independent indicator of decreased propofol dosage for pediatric oncology patients during sedation.

PMID- 29570917 TI - Kinetic of the CMV-specific T-cell immune response and CMV infection in CMV seropositive kidney transplant recipients receiving rabbit anti-thymocyte globulin induction therapy: A pilot study. AB - BACKGROUND: Some studies have suggested that rATG treatment may be associated with an increased incidence of CMV infection and delayed CMV immune response. However, the evidences supporting this matter are scarce. This study aims to characterize the kinetic of the CMV-specific T-cell immune response before and after rATG induction therapy and the relationship with the development of CMV infection in CMV-seropositive kidney transplant recipients. METHODS: An observational prospective study of CMV-seropositive kidney transplant patients that received rATG induction therapy was performed. A pretransplant sample was obtained before the surgery to determine the CMV-specific immunity. CMV viral load (by PCR) and CMV-specific T-cell immune response (by flow cytometry) were determined during the follow-up at 0.5, 1, 2, 3, 6, and 12 months post transplantation. RESULTS: A total of 23 patients were included in the study. CMV prophylaxis was administrated for a media of 90 days after transplantation. At the end of follow-up, 18 (78.3%) patients had CMV-specific immunity with a median value of 0.31% CD8+ CD69+ INF-gamma+ T cells at a median of 16 weeks post transplantation. Five patients never acquired CMV-specific immunity. No statistically significant association between CMV infection and CMV-specific T cell immune response (P = .086) was observed. However, patients with positive pretransplant CMV-specific immunity developed earlier immunity and achieved higher levels of CD8+ CD69+ INF-gamma+ T-cell post-transplantation than patients with negative pretransplant immunity. CONCLUSIONS: CMV-specific immune monitoring in addition to CMV-serology may be useful to stratify patient's risk of CMV infection before transplantation. PMID- 29570920 TI - The nomogram of prenasal thickness and nasal bone ratio and its relationship with nuchal fold in second-trimester fetal ultrasound. AB - AIM: We aimed to define the normal values of second-trimester fetal prenasal thickness and nasal bone length ratio (PNT/NBL) in a low-risk Turkish population and investigate the relationship between the increased PNT and nuchal fold (NF). METHOD: We retrospectively reviewed the data of 650 cases considered to be euploid fetuses who presented to our clinic between December 2013 and September 2014 for a second-line ultrasound between 17 and 24 weeks. Their PNT, NBL, NF and biometric (BPD, HC, AC, FL and HL) measurements were recorded. RESULTS: A total of 650 cases considered to be euploid fetuses were included in this study. There was a linear increase in PNT with the gestational weeks (mean value 3.01 at weeks 17-18 and 3.76 at weeks 23-24). The PNT/NB ratio showed a slight decrease in advancing gestational weeks (mean value 0.57 at weeks 17-18 and 0.50 at weeks 23 24). The 95th percentile value of the PNT/NB ratio, independent of the gestational week, was 0.76. The values of both PNT and NF increased with advancing gestational weeks, but there was no statistically linear increase between PNT and NF (R2 : 0.115). CONCLUSION: In this study, we provided a nomogram of the PNT/NB ratio. Both NF thickness and PNT should be dealt with as two separate markers. Although the formation mechanisms are thought to be the same in both of them, a strong linear relationship does not exist between them. PMID- 29570919 TI - De novo CMV-associated collapsing focal segmental glomerulosclerosis in a kidney transplant recipient. AB - Collapsing focal segmental glomerulosclerosis (FSGS) is a variant of FSGS and is associated with severe nephrotic syndrome and acute kidney injury and can occur after kidney transplantation. The exact mechanism of collapsing FSGS after kidney transplantation is unknown, but potential causes include autoimmune diseases, certain malignancies, bisphosphonates, m-TOR inhibitors, interferon-alpha, HIV infection, and other viruses. We describe a case of de novo Cytomegalovirus (CMV) associated collapsing FSGS in a kidney transplant recipient with a UL97 phosphotransferase mutation that was successfully treated with intravenous ganciclovir, intravenous immunoglobulin, and steroids. PMID- 29570921 TI - Confirmed microsporidial graft infection in a HIV-negative renal transplant recipient: A case report and review of the literature. AB - Microsporidia are intracellular organisms most commonly known to cause opportunistic infection in patients with human immunodeficiency virus (HIV). There have been several case reports of infection in solid organ and bone marrow transplant recipients. Here, we report a case of a non-HIV-infected renal transplant patient with microsporidiosis of the renal tract associated with acute graft dysfunction. We also review the literature of 12 previously reported cases of microsporidiosis in patients with renal transplants who had described graft involvement. We review the pattern of illness as well as the common renal biopsy features when microsporidial infection is associated with renal graft infection. PMID- 29570922 TI - Perspectives of patients with haematological cancer on how clinicians meet their information needs: "Managing" information versus "giving" it. AB - OBJECTIVES: Practitioners treating patients with haematological cancers have extensive clinical information available to give to patients, and patients need to be informed. However, many patients want to be protected from having information that is too detailed or threatening. To illuminate how practitioners can address this dilemma and help patients feel appropriately informed, we explored patients' experience of feeling informed or uninformed. METHODS: Semi structured interviews were conducted with 20 patients who had been diagnosed with haematological cancer and had recently received results from clinical investigations or from evaluations of treatment response. Inductive and interpretive analysis of the transcribed audio-recorded interviews drew on constant comparison. RESULTS: Patients described the need for practitioners carefully to manage the information that they provided, and many felt alarmed by information that they did not experience as having been managed for them. A few patients who had difficulty trusting practitioners were not content with the information provided. CONCLUSIONS: These findings can be understood using attachment theory, whereby practitioners' careful management of information demonstrates their care for patients, and patients' trust in the practitioner enables them to feel informed. It follows that, when patients do not feel informed, the solution will not necessarily be more information but might be to help patients feel more secure in a caring clinical relationship. PMID- 29570923 TI - Cultural factors influencing Japanese nurses' assertive communication: Part 2 - hierarchy and power. AB - Hierarchy and power characterize health-care relationships around the world, constituting a barrier to assertive communication and a risk to patient safety. This issue is more problematic and complex in countries such as Japan, where deep seated cultural values related to hierarchy and power persist. The current paper is the second of two that present the findings from a study exploring Japanese nurses' views and experiences of how cultural values impact assertive communication for health-care professionals. We conducted semistructured interviews with 23 registered nurses, following which data were analyzed using directed content analysis. Two overarching themes emerged from the analysis: hierarchy/power and collectivism. In the present study, we focus on cultural values related to hierarchy and power, including differences in professional status, gender imbalance, seniority/generation gap, bullying, and humility/modesty. The findings from our research provide meaningful insights into how Japanese cultural values influence and constrain nurses' communication and speaking up behaviors, and can be used to inform educational programs designed to teach assertiveness skills. PMID- 29570924 TI - The impact of global warming on germination and seedling emergence in Alliaria petiolata, a woodland species with dormancy loss dependent on low temperature. AB - The impact of global warming on seed dormancy loss and germination was investigated in Alliaria petiolata (garlic mustard), a common woodland/hedgerow plant in Eurasia, considered invasive in North America. Increased temperature may have serious implications, since seeds of this species germinate and emerge at low temperatures early in spring to establish and grow before canopy development of competing species. Dormancy was evaluated in seeds buried in field soils. Seedling emergence was also investigated in the field, and in a thermogradient tunnel under global warming scenarios representing predicted UK air temperatures through to 2080. Dormancy was simple, and its relief required the accumulation of low temperature chilling time. Under a global warming scenario, dormancy relief and seedling emergence declined and seed mortality increased as soil temperature increased along a thermal gradient. Seedling emergence advanced with soil temperature, peaking 8 days earlier under 2080 conditions. The results indicate that as mean temperature increases due to global warming, the chilling requirement for dormancy relief may not be fully satisfied, but seedling emergence will continue from low dormancy seeds in the population. Adaptation resulting from selection of this low dormancy proportion is likely to reduce the overall population chilling requirement. Seedling emergence is also likely to keep pace with the advancement of biological spring, enabling A. petiolata to maintain its strategy of establishment before the woodland canopy closes. However, this potential for adaptation may be countered by increased seed mortality in the seed bank as soils warm. PMID- 29570925 TI - An epigenetic breeding system in soybean for increased yield and stability. AB - Epigenetic variation has been associated with a wide range of adaptive phenotypes in plants, but there exist few direct means for exploiting this variation. RNAi suppression of the plant-specific gene, MutS HOMOLOG1 (MSH1), in multiple plant species produces a range of developmental changes accompanied by modulation of defence, phytohormone and abiotic stress response pathways along with methylome repatterning. This msh1-conditioned developmental reprogramming is retained independent of transgene segregation, giving rise to transgene-null 'memory' effects. An isogenic memory line crossed to wild type produces progeny families displaying increased variation in adaptive traits that respond to selection. This study investigates amenability of the MSH1 system for inducing agronomically valuable epigenetic variation in soybean. We developed MSH1 epi-populations by crossing with msh1-acquired soybean memory lines. Derived soybean epi-lines showed increase in variance for multiple yield-related traits including pods per plant, seed weight and maturity time in both glasshouse and field trials. Selected epi-F2:4 and epi-F2:5 lines showed an increase in seed yield over wild type. By epi-F2:6, we observed a return of MSH1-derived enhanced growth back to wild-type levels. Epi-populations also showed evidence of reduced epitype-by environment (e * E) interaction, indicating higher yield stability. Transcript profiling of epi-lines identified putative signatures of enhanced growth behaviour across generations. Genes related to cell cycle, abscisic acid biosynthesis and auxin response, particularly SMALL AUXIN UP RNAs (SAURs), were differentially expressed in epi-F2:4 lines that showed increased yield when compared to epi-F2:6 . These data support the potential of MSH1-derived epigenetic variation in plant breeding for enhanced yield and yield stability.

AB - Highly functionalized aminocyclopentadienes can be formed through the rearrangement of anions generated from readily prepared 6-silyl-1,2 dihydropyridines by desilylation with fluoride. The scope and generality of the reaction was defined, and diverse transformations were performed on the highly functionalized products. A mechanism and driving force for the rearrangement were identified from experiments and DFT calculations.

Such transgenerational plasticity can be adaptive when it results in higher fitness of the offspring under conditions correlated with those experienced by the mother plant. However, it has rarely been tested if such anticipatory parental effects may be induced with different environments. We grew clonal replicates of Silene vulgaris under control conditions and three types of stress (nutrient deficiency, copper addition and drought), which are known from natural populations of the species. We then subjected offspring from differently treated mother plants to each of the different stress treatments to analyse the influence of maternal and offspring environment on performance and several functional traits. Current stress treatments strongly influenced biomass and functional traits of the plants, mostly in line with responses predicted by the theory of functional equilibrium. Plant performance was also influenced by maternal stress treatments, and some effects independent of initial size differences remained until harvest. In particular, stressed mothers produced offspring of higher fitness than control plants. However, there was no evidence for treatment-specific adaptive transgenerational plasticity, as offspring from a mother plant that had grown in a specific environment did not grow better in that environment than other plants. Our results indicate that the maternal environment may affect offspring traits and performance, but also that this transgenerational plasticity is not necessarily adaptive. PMID- 29570928 TI - An Organogold(III) Difluoride with a trans Arrangement. AB - The trans isomer of the organogold(III) difluoride complex [PPh4 ][(CF3 )2 AuF2 ] has been obtained in a stereoselective way and in excellent yield by reaction of [PPh4 ][CF3 AuCF3 ] with XeF2 under mild conditions. The compound is both thermally stable and reactive. Thus, the fluoride ligands are stereospecifically replaced by any heavier halide or by cyanide, the cyanide affording [PPh4 ][trans (CF3 )2 Au(CN)2 ]. The organogold fluoride complexes [CF3 AuFx ]- (x=1, 2, 3) have been experimentally detected to arise upon collision-induced dissociation of the [trans-(CF3 )2 AuF2 ]- anion in the gas phase. Their structures have been calculated by DFT methods. In the isomeric forms identified for the open-shell species [CF3 AuF2 ]- , the spin density residing on the metal center is found to strongly depend on the precise stereochemistry. Based on crystallographic evidence, it is concluded that Auiii and Agiii have similar covalent radii, at least in their most common square-planar geometry. PMID- 29570929 TI - Multicentre international experience of 532-nm laser photoselective vaporization with GreenLight XPS in men with very large prostates. AB - OBJECTIVES: To describe peri-operative results, functional outcomes and complications of laser photoselective vaporization, using the GreenLight system, of prostate glands >=200 mL in volume. METHODS: Retrospective analysis of a prospectively maintained multicentre database was performed to select a subgroup of patients with very large prostates (volume >=200 mL) treated with the GreenLight XPS laser. A subgroup of patients with prostate volumes 100-200 mL was used for comparison. International Prostate Symptom Score, maximum urinary flow rate, postvoid residual urine volume and prostate-specific antigen levels were measured at 6, 12, 24, 36 and 48 months. Durability was evaluated using benign prostatic hyperplasia re-treatment rate at 12, 24 and 36 months. Additionally, complications were recorded using Clavien-Dindo classification. RESULTS: A total of 33 patients (38%) had prostates >=200 mL. Baseline characteristics were similar between patients with prostates >=200 mL and those with prostates 100-200 mL. Patients with very large prostates (>=200 mL) had longer operating times (129 vs 93 min), less energy delivered, a greater number of fibres used (3 vs 2) and a higher conversion rate to transurethral resection of the prostate (16% vs 4%). In terms of complications and functional outcomes, we did not find any differences between the groups. Retreatment rate was also comparable. CONCLUSIONS: Our results show that PVP GreenLight XPS-180W is an acceptable technique for very large prostates (>=200 mL); however, operating times, energy delivery, fibres used and conversion to TURP are a concern in this particular subgroup. This should be used for patient counselling and surgery planning. PMID- 29570931 TI - Uveal melanoma driver mutations in GNAQ/11 yield numerous changes in melanocyte biology. AB - Uveal melanoma (UM) is the most common primary intraocular cancer and has a high incidence of metastasis, which lacks any effective treatment. Here, we present zebrafish models of UM, which are driven by melanocyte-specific expression of activating GNAQ or GNA11 alleles, GNAQ/11Q209L , the predominant initiating mutations for human UM. When combined with mutant tp53, GNAQ/11Q209L transgenics develop various melanocytic tumors, including UM, with near complete penetrance. These tumors display nuclear YAP localization and thus phenocopy human UM. We show that GNAQ/11Q209L expression induces profound melanocyte defects independent of tp53 mutation, which are apparent within 3 days of development. First, increases in melanocyte number, melanin content, and subcellular melanin distribution result in hyperpigmentation. Additionally, altered melanocyte migration, survival properties, and evasion of normal boundary cues lead to aberrant melanocyte localization and stripe patterning. Collectively, these data show that GNAQ/11Q209L is sufficient to induce numerous protumorigenic changes within melanocytes. PMID- 29570932 TI - PIM2 interacts with tristetraprolin and promotes breast cancer tumorigenesis. AB - Tristetraprolin (TTP) is an AU-rich element-binding protein that regulates mRNA stability and plays important roles in cancer. The mechanisms by which TTP is regulated in breast cancer are poorly understood. Using multiple biochemical approaches, we found that proviral insertion in murine lymphomas 2 (PIM2) is a novel binding partner of TTP. Interestingly, PIM2 decreased TTP protein levels independent of its kinase activity. PIM2 instead targeted TTP protein for degradation via the ubiquitin-proteasome pathway. Furthermore, immunohistochemical staining showed that PIM2 and TTP protein levels were negatively correlated in human breast cancer samples. Indeed, PIM2 overexpression de-repressed TTP-mediated inhibition of breast cancer cell proliferation and migration in vitro and promoted breast tumor xenograft growth in vivo. These findings demonstrate an important role for the PIM2-TTP complex in breast cancer tumorigenesis, suggesting that PIM2 may represent a potential therapeutic target for breast cancer treatment. PMID- 29570930 TI - Cigarette smoke enhances oncogene addiction to c-MET and desensitizes EGFR expressing non-small cell lung cancer to EGFR TKIs. AB - Cigarette smoking is one of the leading risks for lung cancer and is associated with the insensitivity of non-small cell lung cancer (NSCLC) to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). However, it remains undetermined whether and how cigarette smoke affects the therapeutic efficacy of EGFR TKIs. In this study, our data showed that chronic exposure to cigarette smoke extract (CSE) or tobacco smoke-derived carcinogen benzo[alpha]pyrene, B[alpha]P, but not nicotine-derived nitrosamine ketone (NNK), reduced the sensitivity of wild-type EGFR-expressing NSCLC cells to EGFR TKIs. Treatment with TKIs almost abolished EGFR tyrosine kinase activity but did not show an inhibitory effect on downstream Akt and ERK pathways in B[alpha]P-treated NSCLC cells. CSE and B[alpha]P transcriptionally upregulate c-MET and activate its downstream Akt pathway, which is not inhibited by EGFR TKIs. Silencing of c-MET reduces B[alpha]P-induced Akt activation. The CSE-treated NSCLC cells are sensitive to the c-MET inhibitor crizotinib. These findings suggest that cigarette smoke augments oncogene addiction to c-MET in NSCLC cells and that MET inhibitors may show clinical benefits for lung cancer patients with a smoking history.

AB - Diastereo- and enantioselective cycloaddition of 3-nitroindoles with vinyl aziridine was realized under Pd-catalysis using commercially available Walphos as the ligand, affording pyrroloindolines in high yields with high diastereo- and enantioselectivities. The reaction can be scaled up to a gram scale and the reaction products are easily converted to amino pyrroloindoline and other pyrroloindoline derivatives. PMID- 29570934 TI - Non-erythropoietic erythropoietin-derived peptide protects mice from systemic lupus erythematosus. AB - Systemic lupus erythematosus (SLE) is an autoimmune disease, which results in various organ pathologies. However, current treatment towards SLE is suboptimal. Erythropoietin (EPO) has been shown to promote SLE recovery, but clinical application can be limited by its haematopoiesis-stimulating effects. EPO-derived helix-B peptide (ARA290) is non-erythrogenic but has been reported to retain the anti-inflammatory and tissue-protective functions of EPO. Therefore, here we investigated the effects and potential mechanisms of ARA290 on SLE. The administration of ARA290 to pristane-induced SLE and MRL/lpr mice significantly suppressed the level of serum antinuclear autoantibodies (ANAs) and anti-dsDNA autoantibodies, reduced the deposition of IgG and C3, and ameliorated the nephritis symptoms. Moreover, the serum concentrations of inflammatory cytokine IL-6, MCP-1 and TNF-alpha in SLE mice were reduced by ARA290. Further, ARA290 decreased the number of apoptotic cells in kidney. In vitro experiment revealed that ARA290 inhibited the inflammatory activation of macrophages and promoted the phagocytotic function of macrophages to apoptotic cells. Finally, ARA290 did not induce haematopoiesis during treatment. In conclusion, ARA290 ameliorated SLE, which at least could be partly due to its anti-inflammatory and apoptotic cell clearance promoting effects, without stimulating haematopoiesis, suggesting that ARA290 could be a hopeful candidate for SLE treatment. PMID- 29570936 TI - Snake-like surgical forceps for robot-assisted minimally invasive surgery. AB - BACKGROUND: Surgical instruments greatly impact the performance of robot-assisted minimally invasive surgery (RMIS) because they operate on tissues. METHODS: A snake-like surgical instrument, designed with 4 degrees of freedom (DOFs), is proposed for RMIS. The DOFs are as follows: opening and closing motions of the forceps, rotation of the forceps and bi-directional bending of the instrument. The performance of the instrument was evaluated using a prototype in vitro. RESULTS: All DOFs of the instrument were experimentally evaluated and proven sufficient for RMIS. In vitro testing showed that the operations of the proposed model were powerful and steady. CONCLUSIONS: The position and posture of the surgical instrument could be adjusted in the body of the patient by its bending and rotational movements. The proposed model could therefore work as a competent assistant in multi-port RMIS and allow surgeons to perform better. PMID- 29570937 TI - Application of pathways activity profiling to urine metabolomics for screening Qi tonifying biomarkers and metabolic pathways of honey-processed Astragalus. AB - Honey-processed Astragalus, a widely used Qi-tonifying and immunomodulating herb in traditional Chinese medicine, has strengthened the tonic effects and achieved fewer side effects compared with astragali radix in clinical application. Here, we focus on Qi-tonifying biomarkers and pathways of honey-processed Astragalus using urine metabolomics that provide the basis for building the linkage between metabolites in rat urine and its symptoms. The spleen Qi deficiency model group, normal group, astragali radix group, and honey-processed Astragalus group were implemented to evaluate Qi-tonifying effects. Twelve potential biomarkers were screened by multivariate statistical analysis by using ultra high performance liquid chromatography with quadrupole time-of-flight mass spectrometry. Furthermore, pathways activity profiling showed unique pathways that are primarily involved in tryptophan metabolism, tricarboxylic acids cycle, and methionine metabolism. The results demonstrated that metabolomics coupled with pathway activity profiling were promising tools. It might serve as a novel methodological clue to systematically dissect the underlying Qi-tonifying mechanism of honey-processed Astragalus. PMID- 29570938 TI - Building Capacity for Evidence-Based Practice: Understanding How Licensed Practical Nurses (LPNs) Source Knowledge. AB - BACKGROUND: In Canada, all nurses are required to engage in evidence-based practice (EBP) as an entry-to-practice competency; however, there is little research that examines Licensed Practical Nurses' (LPNs') information seeking behaviors or preferred sources of knowledge to conduct EBP. AIMS: Due to the differences in education and roles of LPNs and Registered Nurses (RNs), it is both necessary and important to gain an understanding of how LPNs utilize evidence in their unique nursing practice. The purpose of this study was to investigate how LPNs source knowledge for their nursing practice. METHODS: A descriptive, cross-sectional survey of LPNs from Alberta, Canada asked participants to rank sources of knowledge that inform their practice. Responses were correlated with age and years of practice. Analysis of variance was used to determine if there were significant mean differences between average scores and place of employment. RESULTS: LPN participants used similar sources of knowledge as RNs. The top source of knowledge for both RNs and LPNs was the information they learn about each individual client and the least utilized sources of knowledge were articles published in nursing, medical, and research journals, tradition, and popular media. This finding is consistent with previous studies on RNs that found nurses do not often access current research evidence to inform their practice. LINKING EVIDENCE TO ACTION: Since relatively few LPNs access nursing and research journals, it is important to tailor EBP education information to the workplace context. Future avenues of research might explore the potential of using in-services and webinars to disseminate information and skills training on EBP to the LPNs, as this was a popular source of practice knowledge.

AB - BACKGROUND: Pneumonia is still a leading cause of illness and death in infants worldwide. Lung ultrasound (LUS) is emerging as an extremely valuable non ionizing radiation diagnostic tool in diagnosis and follow up of multiple paediatric pulmonary diseases. OBJECTIVE: To assess the applicability of LUS in diagnosis and follow up of community acquired pneumonia (CAP) in Egyptian infants younger than 1-year old. METHODS: LUS and chest X-ray (CXR) were performed in 50 infants presented with clinical symptoms and signs suggestive of CAP within the first 6 hours of admission in our inpatient department, then follow up LUS was performed 5 days after admission. RESULTS: This study showed that LUS was superior to CXR in initial diagnosis of CAP in infants. LUS detected pneumonia in 49 (98%) compared to 36 (72%) infants diagnosed by CXR (P < .05). On follow up, 5 days later, consolidation patch disappeared in 13 (26.5%) infants, diminished in size in 27 (55.1%) infants, remained at the same size in 2 (4.1%) infants and increased in size in 7 (14.3%) infants. CONCLUSION: This study showed that LUS is superior to CXR in diagnosing infants with CAP who are younger than 1-year old. It also serves as a safe follow up tool and could support the decision of hospital discharge in this category of patients. Further studies with larger sample size and longer follow up duration are recommended to confirm the results of the present study.

PMID- 29570942 TI - Label-free ultra-sensitive visualization of structure below the diffraction resolution limit. AB - For both fundamental study of biological processes and early diagnosis of diseases, information about nanoscale changes in tissue and cell structure is crucial. Nowadays, almost all currently known nanoscopy methods rely upon the contrast created by fluorescent stains attached to the object or molecule of interest. This causes limitations due to the impact of the label on the object and its environment, as well as its applicability in vivo, particularly in humans. In this paper, a new label-free approach to visualize small structure with nano-sensitivity to structural alterations is introduced. Numerically synthesized profiles of the axial spatial frequencies are used to probe the structure within areas whose size can be beyond the diffraction resolution limit. Thereafter, nanoscale structural alterations within such areas can be visualized and objects, including biological ones, can be investigated with sub-wavelength resolution, in vivo, in their natural environment. Some preliminary results, including numerical simulations and experiments, which demonstrate the nano sensitivity and super-resolution ability of our approach, are presented. PMID- 29570943 TI - The Relationship Between Heart Rate Variability, Psychological Flexibility, and Pain in Neurofibromatosis Type 1. AB - Individuals with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PNs) can experience chronic pain. Previous research has examined the relationship between heart rate variability (HRV) and persistent pain. HRV is an index of autonomic nervous system functioning, and reflects the variability in time elapsed between heartbeats. Patients with chronic pain tend to exhibit lower HRV, which has been associated with poor adaptability, or psychological flexibility, to stress. The aim of the current study was to examine relationships between HRV, psychological flexibility, and pain in a sample of adolescents and young adults (AYAs) with NF1 and PNs. AYA participants (n = 40) 16 to 34 years of age with NF1 completed baseline measures of pain and psychological functioning, and underwent a 5-minute electrocardiogram (ECG). A subset of 20 participants completed follow up questionnaires and a second ECG 8 weeks later. Spectral analyses of ECGs yielded a measure of high-frequency heart rate variability (HF-HRV). Baseline correlations revealed that lower HF-HRV is related to greater inflexibility and more pain interference, but not pain intensity. Moreover, psychological inflexibility significantly mediated the relationship between HF-HRV and pain interference. Finally, regression models indicated that baseline psychological inflexibility is a significant predictor of HF-HRV at follow-up and, separately, that baseline HF-HRV significantly predicted pain intensity at follow-up. These findings suggest complex mind-body processes in the experience of pain in NF1, which have not been studied previously. Implications for pain-related interventions and future research are discussed. PMID- 29570944 TI - Anticancer Gold(III) Peptidomimetics: From Synthesis to in vitro and ex vivo Biological Evaluations. AB - Five new AuIII -peptidodithiocarbamato complexes of the type [AuIII Br2 (dtc-AA1 AA2 -OR] (in which AA1 =N-methylglycine (Sar), l/d-Pro; AA2 =l/d-Ala, alpha aminoisobutyric acid (Aib); R=OtBu, triethylene glycol methyl ether), differing with regard to the amino acid sequence and/or the chiral amino acid configuration, were designed to enhance tumor selectivity and bioavailability. The gold(III)-based moiety was functionalized to exploit the targeting properties of the peptidomimetic ligand toward two peptide transporters (namely PEPT1 and PEPT2), which are upregulated in several tumor cells. The compounds were synthesized and fully characterized, mainly by means of elemental analysis, one- and two-dimensional NMR spectroscopy, FT-IR, and UV/Vis spectrophotometry. The crystal structures of three compounds were also solved by X-ray diffraction. In vitro cytotoxicity studies using a panel of human tumor cell lines (A549 [non small-cell lung carcinoma], MCF-7 [breast cancer], A2780 [ovarian carcinoma], H1975 [non-small-cell lung carcinoma], H460 [large-cell lung carcinoma], and A431 [human epidermoid carcinoma]) showed the dtc-Pro-Aib-OtBu derivative to be very effective, with GI50 values much lower than those of cisplatin. This complex was thus selected for evaluating stability under physiological conditions and possible interactions with serum albumin, as well in PARP-1 enzyme inhibition assays and preliminary ex vivo toxicity experiments on healthy rat tissues. PMID- 29570945 TI - Diagnostic and prognostic value of serum Cripto-1 in patients with non-small cell lung cancer. AB - INTRODUCTION: Cripto-1 (CR-1) is a member of the epidermal growth factor (EGF) CFC protein family, which is involved in tumor pathogenesis. OBJECTIVES: This study aimed to explore the diagnostic and prognostic value of serum CR-1 level in patients with non-small cell lung cancer (NSCLC). METHODS: Serum specimens from 312 NSCLC patients and 120 healthy controls were collected. Serum CR-1 level was measured using enzyme-linked immunosorbent assay. RESULTS: The serum CR-1 level was significantly elevated in NSCLC patients compared with healthy controls (P < .001). Higher serum CR-1 level was associated with advanced TNM stage, lymph node metastasis and distant metastasis. With a cutoff value of 1.67 ng/mL, CR-1 showed a good diagnostic performance for NSCLC. Kaplan-Meier log rank analysis revealed that the low serum CR-1 patients had a better overall survival (OS) and progression-free survival (PFS) compared with high CR-1 patients (P = .004 and .001, respectively). Further univariate and multivariate Cox regression analyses showed that serum CR-1 level was an independent risk factor of prognosis of NSCLC patients. CONCLUSIONS: Our study suggests that serum CR-1 level is a useful diagnostic and prognostic marker for NSCLC patients. PMID- 29570946 TI - Serum 25-hydroxyvitamin D levels in hospitalized adults with community-acquired pneumonia. AB - INTRODUCTION: Community-acquired pneumonia (CAP) is the infectious disease with the highest number of deaths worldwide. Several studies have shown an association between vitamin D deficiency and increases susceptibility to respiratory tract infections. OBJECTIVE: The aim of this study was to evaluate the serum 25 hydroxyvitamin D (25OHD) levels in hospitalized adults in general room with CAP. MATERIALS AND METHODS: An observational study was carried out in 207 hospitalized adults of both sex with CAP (>18 years) from Rosario city, Argentina (32 degrees 52' 18"S) between July 2015 and June 2016. RESULTS: In total, 167 patients were included in the data analysis [59% women (57.4 +/- 19.6 years), body mass index 27.2 +/- 7.8 kg/m2 ]. In brief, 63% showed unilobar infiltrate and 37% were multilobar. The CURB-65 index was 66.5% low risk, 16.0% intermediate risk and 17.5% high risk. According to Charlson comorbidity index (CCI) 53.5% had not comorbidity (CCI = 0) and 46.5% showed CCI >= 1. The 25OHD level was: 11.92 +/- 7.6 ng/mL (51.5%: <10 ng/mL, 33.5%: 10-20 ng/mL, 13.2%: 20-30 ng/mL and 1.8%: >30 ng/mL). Higher 25OHD were found in male (female: 10.8 +/- 6.7 ng/mL, male: 13.5 +/- 8.5 ng/mL, P = .02) and 25OHD correlated with age (r = -.17; P = .02). 25 Hydroxyvitamin D was also correlated with CURB65 index (r = -.13; P = .049), CCI (r = -.20, P = .007) and with the 10 years of life expectative (%) (r = .19; P = .008). In addition, higher 25OHD were found with lower CCI (CCI 0 = 13.0 +/- 8.2 ng/mL, CCI >= 1= 10.5 +/- 6.7 ng/mL; P = .0093). CONCLUSIONS: Hospitalized adults with CAP have lower 25OHD levels and would be associated with the severity of CAP. PMID- 29570947 TI - Halogenated Bis(methoxybenzylidene)-4-piperidone Curcuminoids with Improved Anticancer Activity. AB - A series of readily available curcuminoids with a halogenated bis(4-methoxy/4,5 dimethoxybenzylidene)-4-piperidone structure were prepared and analyzed for their cytotoxic impact on eight human cancer cell lines of five different entities. The known 3,4,5-trimethoxybenzylidene curcuminoid 2 a and the new bis-(3-bromophenyl) and bis-(3,5-dibromophenyl) derivatives 3 c and 3 d proved to be more strongly antiproliferative than the known curcuminoid EF24 against six of these cell lines. Compounds 2 a and 3 c caused a distinct increase of reactive oxygen species, which eventually elicited apoptosis in 518A2 melanoma cells. Compound 2 a arrested 518A2 melanoma cells in G1 phase of the cell cycle and had no effect on the expression of pro-metastatic matrix metalloproteinases MMP-2 and MMP-9, whereas 3 c led to an accumulation of 518A2 cells in the G2 /M phase and to a downregulation of MMP-2 expression. In addition, treatment with 2 a and 3 c resulted in significant inhibition of colony formation in HCT116 cells. Both 2 a and 3 c showed antiangiogenic activity, for example, by inhibiting the formation of sub-intestinal veins (SIV) in zebrafish embryos. Compound 3 c was also well tolerated by mice and inhibited the growth of HCT116 colon cancer xenografts. PMID- 29570948 TI - Nucleoside-Based Self-Assembling Drugs for Localized Drug Delivery.

AB - A diradical dication of a 4,4'-di(bis(1,4-methylphenyl)amino)-p-terphenyl oligomer has been characterized in solid-state by Raman spectroscopy and thermo spectroscopy together with quantum chemical calculations. The diradical character has been evaluated on the basis of the Raman spectra and as a function of temperature. A complete understanding of the nature of the changes in solid state has been provided based on a pseudo-Jahn-Teller effect, which is feasible owing to the fine balance between quinoidal/aromatic extension among consecutive rings and steric crowding. This study contributes to the further comprehension of the molecular and electronic structures of these particular diradical molecules with strong implications on the understanding of the nature of chemical bonds in the limits of high electronic correlation or pi-conjugation. PMID- 29570950 TI - Comparison of outcomes of laparoscopy-assisted and open proximal gastrectomy with jejunal interposition for early gastric cancer in the upper third of the stomach: A retrospective observational study. AB - INTRODUCTION: Laparoscopy-assisted proximal gastrectomy with jejunal interposition (LAPG-JI) is not yet widely used because the three anastomotic procedures involved in this operation are technically complicated. This study aimed to describe our surgical procedure for LAPG-JI and assess its feasibility and safety. METHODS: This was a retrospective study of 70 patients who had undergone proximal gastrectomy with jejunal interposition for gastric cancer in the upper third of the stomach between July 2007 and October 2016. Of these patients, 32 underwent LAPG-JI, and 38 underwent open proximal gastrectomy with jejunal interposition. Clinical characteristics and both surgical and postoperative outcomes were compared between LAPG-JI and open proximal gastrectomy with jejunal interposition. RESULTS: The operation time was longer in the LAPG-JI group (189 vs 154 min, P < 0.001) and estimated blood loss was lower (30 vs 180 mL, P < 0.001). There were no differences in the rates of early (9.4% vs 13.2%) or late postoperative complications (12.5% vs 10.5%). No anastomotic leakage was observed in either group. In the LAPG-JI group, the time to first eating was shorter, and the white blood cell counts on postoperative days 1 and 7 and body temperature on postoperative day 3 were lower. The number of additional doses of postoperative analgesia was lower in the LAPG-JI group. Reflux esophagitis graded C according to the Los Angeles classification was observed in only one patient (3.1%) in the LAPG-JI group. CONCLUSION: Although the operation time was longer in the LAPG-JI group, the procedure seemed to be feasible and safe. Also, it offered the advantages of laparoscopic surgery, including less invasiveness and quicker recovery. PMID- 29570951 TI - Ablation of cdk4 and cdk6 affects proliferation of basal progenitor cells in the developing dorsal and ventral forebrain. AB - Little is known about the molecular players driving proliferation of neural progenitor cells (NPCs) during embryonic mouse development. Here, we demonstrate that proliferation of NPCs in the developing forebrain depends on a particular combination of cell cycle regulators. We have analyzed the requirements for members of the cyclin-dependent kinase (cdk) family using cdk-deficient mice. In the absence of either cdk4 or cdk6, which are both regulators of the G1 phase of the cell cycle, we found no significant effects on the proliferation rate of cortical progenitor cells. However, concomitant loss of cdk4 and cdk6 led to a drastic decrease in the proliferation rate of NPCs, specifically the basal progenitor cells of both the dorsal and ventral forebrain at embryonic day 13.5 (E13.5). Moreover, basal progenitors in the forebrain of Cdk4;Cdk6 double mutant mice exhibited altered cell cycle characteristics. Cdk4;cdk6 deficiency led to an increase in cell cycle length and cell cycle exit of mutant basal progenitor cells in comparison to controls. In contrast, concomitant ablation of cdk2 and cdk6 had no effect on the proliferation of NCPs. Together, our data demonstrate that the expansion of the basal progenitor pool in the developing telencephalon is dependent on the presence of distinct combinations of cdk molecules. Our results provide further evidence for differences in the regulation of proliferation between apical and basal progenitors during cortical development. (c) 2018 Wiley Periodicals, Inc.

AB - Maintaining both a high external quantum efficiency and a large open-circuit photovoltage of dye-sensitized solar cells (DSSCs) is a crucial challenge in the process of developing narrow-energy-gap dyes for the capture of infrared solar photons. Herein, we report two donor-acceptor organic dyes, C294 and C295, with a polycyclic heteroaromatic unit, 6,11-dihydrothieno[3',2':8,9]chryseno[10,11,12,1 bcdefg]carbazole (TCC), as the central module of the electron donor, and ethylbenzothiadiazole-benzioc acid as the electron acceptor. The interfacial charge recombination was successfully mitigated by introducing an additional branched aliphatic chain in C295. Furthermore, the O???S nonbonding interaction between the oxygen atom of the alkoxy group and the sulfur atom of the thiophene in C295 controlled the conformation of C295, resulting in a narrow energy-gap. Time-resolved spectroscopic measurements on C294 and the model dye C272 indicated that the elevation of the HOMO energy level decreased the kinetics and yield of hole injection owing to a reduction in the driving force and that the shortened excited-state lifetime caused by the narrowing of the energy gap was unfavorable for electron injection. By fine tuning the composition of the electrolyte, C294 and C295 eventually achieved high power conversion efficiencies of 11.5 % and 12.4 %, respectively, under full sunlight of air mass 1.5 global conditions. PMID- 29570954 TI - Antigen I/II mediates interactions between Streptococcus mutans and Candida albicans. AB - Streptococcus mutans and Candida albicans are frequently co-isolated from dental plaque of children with early childhood caries (ECC) and are only rarely found in children without ECC, suggesting that these species interact in a manner that contributes to the pathogenesis of ECC. Previous studies have demonstrated that glucans produced by S. mutans are crucial for promoting the formation of biofilm and cariogenicity with C. albicans; however, it is unclear how non-glucan S. mutans biofilm factors contribute to increased biofilm formation in the presence of C. albicans. In this study we examined the role of S. mutans antigen I/II in two-species biofilms with C. albicans, and determined that antigen I/II is important for the incorporation of C. albicans into the two-species biofilm and is also required for increased acid production. The interaction is independent of the proteins Als1 and Als3, which are known streptococcal receptors of C. albicans. Moreover, antigen I/II is required for the colonization of both S. mutans and C. albicans during co-infection of Drosophila melanogaster in vivo. Taken together, these results demonstrate that antigen I/II mediates the increase of C. albicans numbers and acid production in the two-species biofilm, representing new activities associated with this known S. mutans adhesin.

AB - Migratory birds move through multiple habitats and encounter a diverse suite of parasites. This raises concern over migrants' role in transporting infectious disease between breeding and wintering grounds, and along migratory flyways. Trade-offs between flight and immune defenses could interfere with infected individuals' migratory timing and success, potentially affecting infection dynamics. However, experimental evidence that parasitic infection affects migratory preparation or timing remains scant. We hypothesized that birds encountering hematozoan parasites shortly before migration incur physical costs (reduced body condition) and behavioral costs (delayed migration), due to the infection itself and/or to the demands of mounting an immune response. We experimentally inoculated song sparrows (Melospiza melodia) with Plasmodium shortly before fall migration. We monitored infection and body composition for 2 weeks after inoculation, and used radiotelemetry to track timing of migratory departure for another 7 weeks after release. Inoculated individuals that resisted infection had lower lean mass 12 days post exposure, relative to controls and infected individuals. This suggests trade-offs between body composition and immune defenses that might reduce migration success of resistant individuals. Despite group differences in body composition prior to release, we did not detect significant differences in timing of migration departure several weeks later. Thus, malarial infection did not appear to incur detectable costs to body composition or to migratory timing, at least when exposure occurs several weeks before migration. This study is novel considering not only the costs of infection, but also the costs of resisting infection, in an experimental context.

AB - AIMS/INTRODUCTION: Pancreatic alpha-cell area and the alpha- to beta-cell area ratio (alpha/beta) might be associated with glucose tolerance. The aim was to clarify how these histological parameters change as glucose tolerance deteriorates. MATERIALS AND METHODS: We analyzed pancreatic tissues obtained from pancreatectomies of 43 patients. We evaluated the relationships between alpha cell area or the alpha/beta and various clinical parameters. Additionally, we analyzed alpha-cell proliferation and the expression patterns of various pancreatic transcription factors. RESULTS: The alpha/beta in individuals with longstanding (previously diagnosed) type 2 diabetes (0.36 +/- 0.12) was higher than that in those with normal glucose tolerance (0.18 +/- 0.10; P < 0.01), impaired glucose tolerance (0.17 +/- 0.12; P < 0.05) and newly diagnosed diabetes (0.17 +/- 0.12; P < 0.05). In all participants, glycated hemoglobin (HbA1c) correlated with relative alpha-cell area (P = 0.010). Diabetes duration (P = 0.004), HbA1c (P < 0.001) and plasma glucose levels (P = 0.008) were significantly correlated with the alpha/beta in single regression analyses, and diabetes duration was the only independent and significant determinant in stepwise multiple regression analyses (P = 0.006). The alpha-cell Ki67-positive ratio in patients with HbA1c >=6.5% was significantly higher than that in patients with HbA1c <6.5% (P = 0.022). We identified beta-cells that expressed aristaless-related homeobox and alpha-cells that did not express aristaless related homeobox at all glucose tolerance stages. Aristaless-related homeobox and NK homeobox 6.1 expression patterns varied in insulin and glucagon double positive cells. CONCLUSIONS: The pancreatic alpha/beta increases after type 2 diabetes onset and correlates with diabetes duration. This change might occur through alpha-cell proliferation and phenotypic changes in pancreatic endocrine cells. PMID- 29570957 TI - Sensitive Leptospira DNA detection using tapered optical fiber sensor. AB - This paper presents the development of tapered optical fiber sensor to detect a specific Leptospira bacteria DNA. The bacteria causes Leptospirosis, a deadly disease but with common early flu-like symptoms. Optical single mode fiber (SMF) of 125 MUm diameter is tapered to produce 12 MUm waist diameter and 15 cm length. The novel DNA-based optical fiber sensor is functionalized by incubating the tapered region with sodium hydroxide (NaOH), (3-Aminopropyl) triethoxysilane and glutaraldehyde. Probe DNA is immobilized onto the tapered region and subsequently hybridized by its complementary DNA (cDNA). The transmission spectra of the DNA based optical fiber sensor are measured in the 1500 to 1600 nm wavelength range. It is discovered that the shift of the wavelength in the SMF sensor is linearly proportional with the increase in the cDNA concentrations from 0.1 to 1.0 nM. The sensitivity of the sensor toward DNA is measured to be 1.2862 nm/nM and able to detect as low as 0.1 fM. The sensor indicates high specificity when only minimal shift is detected for non-cDNA testing. The developed sensor is able to distinguish between actual DNA of Leptospira serovars (Canicola and Copenhageni) against Clostridium difficile (control sample) at very low (femtomolar) target concentrations.

AB - Cognitive impairments due to electroconvulsive therapy (ECT), traumatic brain injury (TBI), and neurologic and psychiatric disorders are prevalent. Cholinergic and glutamatergic pathways, alpha-7 nicotinic acetylcholine (alpha-7nACh) receptor, and N-methyl-d-aspartate (NMDA) receptor are potential pathophysiologic mechanisms in all of these conditions. Galantamine not only is an acetylcholinesterase inhibitor but has a dual mode of action as a alpha-7nACh receptor modulator as well. Memantine is a noncompetitive NMDA receptor antagonist. Galantamine and memantine are approved by the US Food and Drug Administration (FDA) for the treatment of Alzheimer's disease (AD). Galantamine and memantine have shown efficacy for the treatment of ECT- and TBI-induced cognitive impairments. The kynurenine pathway (KP) metabolites are associated with ECT- and TBI-induced cognitive impairments and several neurologic and psychiatric disorders. Kynurenic acid (KYNA) is an antagonist to the alpha-7nACh and NMDA receptors. The galantamine-memantine combination has been shown to modulate several KP metabolites in schizophrenia, thereby improving several cognitive domains. There are no FDA-approved treatments for ECT-induced cognitive impairments or for cognitive impairments in neurologic and psychiatric disorders except AD. This article is timely because the pharmacology of cognition as a panacea for neuropsychiatric diseases was recently published. Hence, randomized controlled trials are warranted with this combination in these diseases, with KYNA and mismatch negativity as novel target engagement. Future positive studies may lead to standard of care, which is likely to significantly improve socio occupational functioning.

AB - Objective: To describe sociodemographic and clinical characteristics of suicide decedents and to explore the pattern of clinical and suicide risk assessment in primary care settings. Methods: A 3-year case series of consecutive suicides (January 1, 2012, to December 31, 2014) in Southwestern Ontario, Canada, identified by the Office of the Chief Coroner of Ontario and Ontario Forensic Pathology Service (OCC/OFPS) was conducted. Clinicians who provided care to suicide decedents completed a confidential suicide questionnaire offered online through a secured portal or by hardcopy. Results: A total of 476 suicide cases were analyzed using data extracted from the OCC/OFPS files or provided by clinicians who had completed the survey. Hanging (42.8%) was the most common method of suicide, followed by self-poisoning (17.9%). More than half of the decedents (51.8%) used psychotropic medications, and 29.4% used opiates to self poison. Typically, these self-poisonings involved prescribed medications (70.6%). Over two-thirds (67.4%) of suicide decedents had consulted their primary care physician prior to their deaths, and 63.6% had been seen by a physician within 28 days of their death. Suicide risk assessments were reportedly conducted in 87.1% of these visits. Of those who were assessed, the immediate risk of suicide was deemed to be absent in 39.8%, low in 50.0%, moderate in 8.3%, and high in only 1.9%. Conclusion: The findings from this confidential survey may be important for the formulation of recommendations that could improve suicide prevention in primary care practice. PMID- 29570963 TI - Computer-Assisted Cognitive-Behavior Therapy for Depression in Primary Care: Systematic Review and Meta-Analysis. AB - Objective: To examine evidence for the effectiveness of computer-assisted cognitive-behavior therapy (CCBT) for depression in primary care and assess the impact of therapist-supported CCBT versus self-guided CCBT. Methods: A search for randomized studies of CCBT compared to control groups for treating depression in primary care settings was conducted using Ovid MEDLINE, PsycINFO, PubMed, and Scopus. We extracted the following information from the studies that met inclusion criteria: mean depression rating scale scores before and after treatment, number of patients, type of control group and CCBT program, therapist support time and method of support, and treatment completion rate. Meta-analyses compared differences between posttreatment mean scores in each condition, as well as mean scores at follow-up. Study quality and possible bias also were assessed. Results: Eight studies of CCBT for depression in primary care met inclusion criteria. The overall effect size was g = 0.258, indicating a small but significant advantage for CCBT over control conditions. Therapist support was provided in 4 of the 8 studies. The effect size for therapist-supported CCBT was g = 0.372-a moderate effect. However, the effect size for self-guided CCBT was g = 0.038, indicating little effect. Conclusions: Implementation of therapist supported CCBT in primary care settings could enhance treatment efficiency, reduce cost, and improve access to effective treatment for depression. However, evidence to date suggests that self-guided CCBT offers no benefits over usual primary care.

A Meta-Analysis of Double Blind, Randomized, Controlled Trials. AB - BACKGROUND: Numerous case reports have reported psychotic worsening when switching to or adding aripiprazole in patients with schizophrenia. The risk of psychotic worsening related to aripiprazole was evaluated through a systematic review and meta-analysis. DATA SOURCES: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were systematically searched using the following keywords: (schizophr* or schizoaff*) AND aripiprazole, with a limitation of randomized controlled trial and English language (last search: September 9, 2016) by the authors in an independent fashion. STUDY SELECTION: Double-blind, randomized, controlled trials involving a switch to or addition of aripiprazole in schizophrenia spectrum disorders were selected by the authors in an independent fashion. A total of 22 studies (13 switching and 9 adding studies) involving 5,769 patients that met eligibility criteria were identified and included in the meta-analysis. DATA EXTRACTION: Number of patients who experienced psychotic worsening, agitation, or anxiety as well as those who discontinued the study due to all causes, lack of efficacy, or adverse events were extracted. RESULTS: Psychotic worsening was reported as an adverse event in all studies. No significant difference in the risk of psychotic worsening was found between switching to aripiprazole and switching to another antipsychotic (RR = 1.17, 95% CI = 0.97-1.42, P = .10); however, switching to aripiprazole was related to a significantly greater risk of study discontinuation due to lack of efficacy (RR = 1.46, 95% CI = 1.10-1.93, P = .009). Lack of data resulted in no conclusive results as to clinical risks of adding aripiprazole. CONCLUSIONS: Findings suggest that there is no direct evidence that a switch to aripiprazole is related to risk of psychotic worsening in participants in clinical trials, although a switch to aripiprazole may be associated with a higher risk of study discontinuation due to lack of efficacy. PMID- 29570966 TI - Is Cannabis Use Associated With Increased Risk of Cigarette Smoking Initiation, Persistence, and Relapse? Longitudinal Data From a Representative Sample of US Adults. AB - OBJECTIVE: The current study prospectively investigated the relationship between cannabis use and cigarette smoking initiation, persistence, and relapse during a 3-year period among adults in the United States. METHODS: Analyses included respondents who completed Waves 1 (2001-2002) and 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions and responded to questions about cannabis use and smoking status (n = 34,639). Multivariable logistic regression models were used to calculate the odds of cigarette use at Wave 2 among Wave 1 daily smokers, nondaily smokers, former smokers, and nonsmokers by Wave 1 cannabis use. RESULTS: In unadjusted analyses, Wave 1 cannabis use was associated with increased odds of Wave 2 daily and nondaily smoking for Wave 1 nonsmokers (daily OR = 2.90; 95% CI, 2.10-4.00; nondaily OR = 4.45; 95% CI, 3.97 5.00) and Wave 2 relapse to daily and nondaily smoking for Wave 1 former smokers (daily OR = 4.18, 95% CI, 3.01-5.81; nondaily OR = 5.24; 95% CI, 3.74-7.34). Wave 1 cannabis use was associated with decreased odds of Wave 2 smoking cessation for Wave 1 daily cigarette smokers (OR = 0.57; 95% CI, 0.51-0.64). The associations remained significant for daily smoking initiation (OR = 1.43; 95% CI, 1.06-1.93), daily smoking relapse (OR = 1.47; 95% CI, 1.00-2.16), and smoking cessation (OR = 0.77; 95% CI, 0.69-0.87) after adjusting for demographics and psychiatric disorders. Associations remained significant for nondaily smoking initiation (OR = 1.85; 95% CI, 1.59-2.16) and nondaily smoking relapse (OR = 1.63; 95% CI, 1.05 2.54) after adjusting for these covariates as well as for alcohol and substance use disorders. CONCLUSIONS: Cannabis use was associated with increased initiation of, persistence of, and relapse to cigarette smoking. Additional attention to cannabis use in tobacco control efforts and in clinical settings aimed at reducing cigarette smoking and smoking-related negative consequences may be warranted.

AB - Objective: To examine family caregiver perspectives on cooperative communication surrounding pharmacologic and nonpharmacologic resources for the treatment of dementia-related behavioral symptoms. Methods: Personal narrative interviews were conducted by the primary investigator with 13 family caregivers from October 2014 to April 2015. The recorded interviews were then transcribed and coded. Models detailing the caregivers' resource utilization in regard to behavioral symptom management were produced for each participant and then summarized on the basis of recurring themes. Results: There is a significant gap in the coordination and communication between physician services and caregiver community resources to aid in the behavioral management of family members with dementia. Physicians tend to rely on pharmacologic management independent of community resources and did not seem to be integrated or involved with recommendations from community resources. Conclusions: Better integration of caregiver resources is necessary to help caregivers in the management of dementia-related behavioral symptoms. PMID- 29570969 TI - Tardive Dyskinesia: Recognition, Patient Assessment, and Differential Diagnosis. AB - Tardive dyskinesia (TD) is an involuntary movement disorder associated with antipsychotic treatment. Because of the serious and potentially irreversible nature of TD, accurate diagnosis is crucial. However, diagnosing TD can be challenging, since the subtle and often fluctuating symptoms can be easily mistaken for symptoms of mental illness or other side effects. Although the risk of developing TD in relation to treatment with second-generation antipsychotics is lower than that associated with first-generation antipsychotics, the risk still exists and may be greater than once believed. Clinicians prescribe antipsychotics for a variety of illnesses and may underestimate the possibility of a patient developing TD, thus missing early signs of the disorder. In this ACADEMIC HIGHLIGHTS, experts review the prevalence, phenomenology, risk factors, and impact of TD, illustrated by case examples, and provide valuable clinical information to guide early recognition and accurate diagnosis.

PMID- 29570970 TI - Sources of Prescription Medication Misuse Among Young Adults in the United States: The Role of Educational Status. AB - OBJECTIVE: This study examined prescription drug misuse (PDM), sources of PDM, and substance use disorder (SUD) symptoms as a function of educational status among US young adults based on a large nationally representative sample. METHODS: Data from the 2009-2014 National Survey on Drug Use and Health came from a sample of 106,845 young adults aged 18-25 years. Respondents were categorized by educational status and PDM, sources of PDM, other substance use, and SUD symptoms, with analyses performed separately for prescription opioids, stimulants, and sedatives/tranquilizers. RESULTS: Prescription opioid (past-year: 11.9%) and sedative/tranquilizer (past-year: 5.8%) misuse were most prevalent among young adults not attending college, especially among high school dropouts. In contrast, full-time college students and college graduates had the highest rates of prescription stimulant misuse (past-year: 4.3% and 3.9%, respectively). Obtaining prescription medications from friends/relatives for free was the most common source of PDM, especially among college students/graduates. Prescription drug misusers who obtained medications from theft/fake prescriptions, purchases, or multiple sources were more likely to report past-year SUDs and had the most severe overall risk profile of concurrent substance use and SUD. More than 70% of past-month prescription drug misusers who reported multiple sources for PDM had at least 1 past-year SUD. CONCLUSIONS: Sources of PDM vary by educational status among US young adults, and the college environment is associated with sharing prescription medications. Clinicians can help assess an individual's risk for SUD by determining whether the individual engaged in PDM and the source of prescription medication the individual is misusing. PMID- 29570971 TI - Phenotypic Assessment of Drug Metabolic Pathways and P-Glycoprotein in Patients Treated With Antidepressants in an Ambulatory Setting. AB - OBJECTIVE: Drug-metabolizing enzymes (DMEs), such as cytochrome P450 (CYP) enzymes, and transporters have emerged as major determinants of variability in drug metabolism and response. This study investigated the association between CYP and P-glycoprotein activities and plasma antidepressant concentration in an outpatient clinical setting. Secondary outcomes were antidepressant efficacy and tolerance. We also describe phenotypes in patients treated with antidepressants and evaluate the tolerance of a minimally invasive phenotyping approach. METHODS: From January 2015 to August 2015, 64 patients on a stable antidepressant regimen underwent a simultaneous assessment of steady-state antidepressant concentration and DME (CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A) and P-glycoprotein transporter activity using a cocktail phenotyping approach. Psychiatric diagnoses were in accordance with DSM-5. RESULTS: We observed a high proportion of subjects (> 20%) with reduced activity of CYP2C19, CYP2D6, CYP3A4, and P-glycoprotein. As expected, higher CYP activity for major metabolic pathways was associated with lower concentration of the parent compound (CYP2C19 and escitalopram, P = .025; CYP2D6 and fluoxetine, P < .001; CYP2C19 and sertraline, P = .001), higher concentration of the metabolite (CYP2D6 and O-desmethylvenlafaxine, P = .007), and higher metabolite-to-parent drug ratio (CYP2C19 and escitalopram, P = .03; CYP2D6 and fluoxetine, P < .001; CYP2C19 and sertraline, P = .048; CYP2B6 and sertraline, P = .006). Phenotyping also highlighted the relevance of a minor metabolic pathway for venlafaxine (CYP3A4). Insufficient response and adverse reactions to antidepressants were not significantly associated with plasma antidepressant concentration, DME, or P-glycoprotein activity. Tolerance of the phenotypic test in ambulatory settings was found to be excellent. CONCLUSIONS: The phenotypic assessment of DMEs and a transporter is a valuable, well-tolerated method to explore the interindividual variability in drug disposition in clinical settings. The method is able to account for the inhibitory activity of antidepressants themselves and for polymedication, which is frequent in this population of refractory depressed patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02438072. PMID- 29570972 TI - Shotgun Analysis of Diacylglycerols Enabled by Thiol-ene Click Chemistry. AB - Diacylglycerols (DAGs) are a subclass of neutral lipids actively involved in cell signaling and metabolism. Alteration in DAG metabolism has been associated with onset and progression of several human-related diseases. The structural diversity of DAGs and their low concentrations in biological samples call for the development of methods that are capable of sensitive identification and quantitation of each DAG species as well as rapid profiling when a biochemical pathway is perturbed. In this work, the thiol-ene click chemistry has been employed to introduce a charge-tag, namely, cysteamine (CA), at a carbon-carbon double bond (C?C) of unsaturated DAGs. This one-pot photochemical derivatization is fast (within 1 min), universal (monotagging) for DAGs varying in fatty acyl chain lengths and the number of C?Cs, and suitable for small sample volume (e.g., 1-50 MUL plasma). Because of the presence of the amine group in CA, tagged DAGs showed at least 10 times increase in response to electrospray ionization as compared to conventional ammonium adduct formation. Low-energy collision-induced dissociation of CA tagged DAGs allowed confident assignment of fatty acyl composition. A neutral loss scan based on characteristic 95 Da loss (a combined loss of CA and H2O) of tagged DAGs has been established as a sensitive means for unsaturated DAG detection (limit of detection = 100 pM) and quantitation from mixtures. The analytical utility of CA tagging was demonstrated by shotgun analysis of unsaturated DAGs in human plasma, including samples from type 2 diabetes mellitus patients. PMID- 29570974 TI - Online Monitoring of Intraoperative Exhaled Propofol by Acetone-Assisted Negative Photoionization Ion Mobility Spectrometry Coupled with Time-Resolved Purge Introduction. AB - Online monitoring of exhaled propofol concentration is important for anesthetists to provide adequate anesthesia as propofol concentrations in plasma and breath are correlated reasonably well. Exhaled propofol could be detected by 63Ni ion mobility spectrometry in negative ion mode; however, the radioactivity of 63Ni source restricts its clinical application due to safety, environmental, and regulatory concerns. An acetone-assisted negative photoionization ion mobility spectrometer (AANP-IMS) using a side-mounted vacuum ultraviolet (VUV) lamp in the unidirectional (UD) flow mode was developed for sensitive measurement of exhaled propofol by producing a high percentage of O2-(H2O) n. An adsorption sampling and time-resolved purge introduction system was developed to eliminate the interference of residual inhaled anesthetic sevoflurane based on their different adsorptions between propofol and sevoflurane on the inwall of the fluorinated ethylene propylene (FEP) sample loop. The effects of the inner diameter and the length of the sample loop on the signal intensity of propofol and the time resolution between propofol and sevoflurane were theoretically and experimentally investigated. A sample loop with 3 mm i.d. and 150 cm length allowed sensitive measurement of exhaled propofol with a response time of 4 s, a linear response range for propofol was achieved to be 0.2 to 14 ppbv with a limit of detection (LOD) of 60 pptv, and the quantification of propofol was not influenced by the change of the sevoflurane concentration. Finally, the performance of monitoring exhaled propofol during surgery was demonstrated on a patient undergoing laparoscopic distal pancreatectomy combined with cholecystectomy. PMID- 29570973 TI - Global Distribution of Human-Associated Fecal Genetic Markers in Reference Samples from Six Continents. AB - Numerous bacterial genetic markers are available for the molecular detection of human sources of fecal pollution in environmental waters. However, widespread application is hindered by a lack of knowledge regarding geographical stability, limiting implementation to a small number of well-characterized regions. This study investigates the geographic distribution of five human-associated genetic markers (HF183/BFDrev, HF183/BacR287, BacHum-UCD, BacH, and Lachno2) in municipal wastewaters (raw and treated) from 29 urban and rural wastewater treatment plants (750-4 400 000 population equivalents) from 13 countries spanning six continents. In addition, genetic markers were tested against 280 human and nonhuman fecal samples from domesticated, agricultural and wild animal sources. Findings revealed that all genetic markers are present in consistently high concentrations in raw (median log10 7.2-8.0 marker equivalents (ME) 100 mL-1) and biologically treated wastewater samples (median log10 4.6-6.0 ME 100 mL-1) regardless of location and population. The false positive rates of the various markers in nonhuman fecal samples ranged from 5% to 47%. Results suggest that several genetic markers have considerable potential for measuring human-associated contamination in polluted environmental waters. This will be helpful in water quality monitoring, pollution modeling and health risk assessment (as demonstrated by QMRAcatch) to guide target-oriented water safety management across the globe. PMID- 29570975 TI - In Situ Observation of Chymotrypsin Catalytic Activity Change Actuated by Nonheating Low-Frequency Magnetic Field. AB - Magnetomechanical modulation of biochemical processes is a promising instrument for bioengineering and nanomedicine. This work demonstrates two approaches to control activity of an enzyme, alpha-chymotrypsin immobilized on the surface of gold-coated magnetite magnetic nanoparticles (GM-MNPs) using a nonheating low frequency magnetic field (LF MF). The measurement of the enzyme reaction rate was carried out in situ during exposure to the magnetic field. The first approach involves alpha-chymotrypsin-GM-MNPs conjugates, in which the enzyme undergoes mechanical deformations with the reorientation of the MNPs under LF MF (16-410 Hz frequency, 88 mT flux density). Such mechanical deformations result in conformational changes in alpha-chymotrypsin structure, as confirmed by infrared spectroscopy and molecular modeling, and lead to a 63% decrease of enzyme initial activity. The second approach involves an alpha-chymotrypsin-GM-MNPs/trypsin inhibitor-GM-MNPs complex, in which the activity of the enzyme is partially inhibited. In this case the reorientation of MNPs in the field leads to disruption of the enzyme-inhibitor complex and an almost 2-fold increase of enzyme activity. The results further demonstrate the utility of magnetomechanical actuation at the nanoscale for the remote modulation of biochemical reactions. PMID- 29570976 TI - Spatial Systems Lipidomics Reveals Nonalcoholic Fatty Liver Disease Heterogeneity. AB - Hepatocellular lipid accumulation characterizes nonalcoholic fatty liver disease (NAFLD). However, the types of lipids associated with disease progression are debated, as is the impact of their localization. Traditional lipidomics analysis using liver homogenates or plasma dilutes and averages lipid concentrations, and does not provide spatial information about lipid distribution. We aimed to characterize the distribution of specific lipid species related to NAFLD severity by performing label-free molecular analysis by mass spectrometry imaging (MSI). Fresh frozen liver biopsies from obese subjects undergoing bariatric surgery ( n = 23) with various degrees of NAFLD were cryosectioned and analyzed by matrix assisted laser desorption/ionization (MALDI)-MSI. Molecular identification was verified by tandem MS. Tissue sections were histopathologically stained, annotated according to the Kleiner classification, and coregistered with the MSI data set. Lipid pathway analysis was performed and linked to local proteome networks. Spatially resolved lipid profiles showed pronounced differences between nonsteatotic and steatotic tissues. Lipid identification and network analyses revealed phosphatidylinositols and arachidonic acid metabolism in nonsteatotic regions, whereas low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) metabolism was associated with steatotic tissue. Supervised and unsupervised discriminant analysis using lipid based classifiers outperformed simulated analysis of liver tissue homogenates in predicting steatosis severity. We conclude that lipid composition of steatotic and nonsteatotic tissue is highly distinct, implying that spatial context is important for understanding the mechanisms of lipid accumulation in NAFLD. MSI combined with principal component linear discriminant analysis linking lipid and protein pathways represents a novel tool enabling detailed, comprehensive studies of the heterogeneity of NAFLD. PMID- 29570977 TI - Cystamine and Disulfiram Inhibit Human Transglutaminase 2 via an Oxidative Mechanism. AB - The catalytic activity of transglutaminase 2 (TG2), a ubiquitously expressed mammalian enzyme, is regulated by multiple post-translational mechanisms. Because elevated activity of TG2 in the extracellular matrix is associated with organ specific diseases such as celiac disease and renal fibrosis, there is growing therapeutic interest in inhibitors of this enzyme. Cystamine, a symmetric disulfide compound, is one of the earliest reported TG2 inhibitors. Despite its widespread use as a tool compound to block TG2 activity in vitro and in vivo, its mechanism of action has remained unclear. Here, we demonstrate that cystamine irreversibly inhibits human TG2 ( kinh/ Ki = 1.2 mM-1 min-1) via a mechanism fundamentally distinct from those proposed previously. Through mass spectrometric disulfide mapping and site-directed mutagenesis, we show that cystamine promotes the formation of a physiologically relevant disulfide bond between Cys370 and Cys371 that allosterically abrogates the catalytic activity of human TG2. This discovery led us to evaluate clinically useful thiol -> disulfide oxidants for TG2 inhibitory activity. It is demonstrated that disulfiram, a relatively safe oral thiuram disulfide, is a fairly potent TG2 inhibitor ( kinh/ Ki = 8.3 mM-1 min-1) and may therefore provide a practical tool for clinically validating this emerging therapeutic target in intestinal disorders such as celiac disease. PMID- 29570978 TI - Direct Detection of Small n-Alkanes at Sub-ppbv Level by Photoelectron-Induced O2+ Cation Chemical Ionization Mass Spectrometry at kPa Pressure. AB - Direct mass spectrometric measurements of saturated hydrocarbons, especially small n-alkanes, remains a great challenge because of low basicity and lack of ionizable functional groups. In this work, a novel high-pressure photoelectron induced O2+ cation chemical ionization source (HPPI-OCI) at kPa based on a 10.6 eV krypton lamp was developed for a time-of-flight mass spectrometer (TOFMS). High-intensity O2+ reactant ions were generated by photoelectron ionization of air molecules in the double electric field ionization region. The quasi-molecular ions, [M-H]+, of C3-C6 n-alkanes, gradually dominated in the mass spectra when the ion source pressure was elevated from 88 to 1080 Pa, with more than 3 orders of magnitude improvement in signal intensity. As a result, the achieved limits of detection were lowered to 0.14, 0.11, 0.07, and 0.1 ppbv for propane, n-butane, n pentane, and n-hexane, respectively. The performance of the HPPI-OCI TOFMS was first demonstrated by analysis of exhaled small n-alkanes from healthy smokers and nonsmokers. Then the concentration variations of exhaled small n-alkanes of four healthy volunteers were analyzed after alcohol consumption to explore the alcohol-hepatoxicity-related oxidative stress. In summary, this work provides new insights for controlling the O2+-participating chemical ionization by adjusting the ion source pressure and develops a novel direct mass spectrometric method for sensitive measurements of mall n-alkanes. PMID- 29570980 TI - Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry. AB - A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination with MS/MS techniques and quantum chemical calculations to develop a rapid method for identification. DMS is used as a prefilter to separate positional isomers prior to subsequent identification by mass spectrometric analyses. Collision induced dissociation of each DMS separated species is used to reveal fragmentation patterns that can be correlated to specific isomer structures. Analysis of the experimental data and supporting quantum chemical calculations show that methylene-hydroxylated and methoxy-containing phenyl ring hydroxylated transformation products are observed. The proposed methodology outlines a high throughput technique to determine transformation products of small molecules accurately, in a short time and requiring minimal sample concentrations (<25 ng/mL). PMID- 29570979 TI - Sensitivity of Ambient Atmospheric Formaldehyde and Ozone to Precursor Species and Source Types Across the United States. AB - Formaldehyde (HCHO) is an important air pollutant from both an atmospheric chemistry and human health standpoint. This study uses an instrumented photochemical Air Quality Model, CMAQ-DDM, to identify the sensitivity of HCHO concentrations across the United States (U.S.) to major source types and hydrocarbon speciation. In July, biogenic sources of hydrocarbons contribute the most (92% of total hydrocarbon sensitivity), split between isoprene and other alkenes. Among anthropogenic sources, mobile sources of hydrocarbons and nitrogen oxides (NO x) dominate. In January, HCHO is more sensitive to anthropogenic hydrocarbons than biogenic sources, especially mobile sources and residential wood combustion (36% of national hydrocarbon sensitivity). While ozone (O3) is three times more sensitive to NO x than hydrocarbons across most areas of the U.S., HCHO is six times more sensitive to hydrocarbons than NO x, largely due to sensitivity to biogenic precursors and the importance of low-NO x chemistry. In winter, both HCHO and O3 show negative sensitivity to NO x (increases with the removal of NO x), although O3 increases are larger. Relative sensitivities do not change substantially across different regions of the country. PMID- 29570981 TI - Discovery of a Pederin Family Compound in a Nonsymbiotic Bloom-Forming Cyanobacterium. AB - The pederin family includes a number of bioactive compounds isolated from symbiotic organisms of diverse evolutionary origin. Pederin is linked to beetle induced dermatitis in humans, and pederin family members possess potent antitumor activity caused by selective inhibition of the eukaryotic ribosome. Their biosynthesis is accomplished by a polyketide/nonribosomal peptide synthetase machinery employing an unusual trans-acyltransferase mechanism. Here, we report a novel pederin type compound, cusperin, from the free-living cyanobacterium Cuspidothrix issatschenkoi (earlier Aphanizomenon). The chemical structure of cusperin is similar to that of nosperin recently isolated from the lichen cyanobiont Nostoc sharing the tehrahydropyran moiety and major part of the linear backbone. However, the cusperin molecule is extended by a glycine residue and lacks one hydroxyl substituent. Pederins were previously thought to be exclusive to symbiotic relationships. However, C. issatschenkoi is a nonsymbiotic planktonic organism and a frequent component of toxic water blooms. Cusperin is devoid of the cytotoxic activity reported for other pederin family members. Hence, our findings raise questions about the role of pederin analogues in cyanobacteria and broaden the knowledge of ecological distribution of this group of polyketides. PMID- 29570983 TI - Survivorship Care Planning for Young Adults After Cancer Treatment: Understanding Care Patterns and Patient-Reported Outcomes. AB - PURPOSE: Young adult survivors (YAS) of cancer experience late effects of treatment similar to older adult survivors (AS). Online health tools such as Internet-based survivorship care plans (SCPs) can provide access to information about late effects and symptom management, but little is known about SCP patterns of use among YAS. METHODS: An Internet-based cross-sectional survey was completed over 24 months. Participants were individuals diagnosed with cancer between 18 and 39 years (YAS, n = 611) or 40-60 years (AS, n = 1742), who were 2-20 years postdiagnosis, and who created an Internet-based SCP. Demographics, treatment related variables, satisfaction with SCP, communication of SCP, and patient reported late effects (fatigue, neurocognitive, sexual, cardiovascular, pulmonary, or second cancers) were collected. RESULTS: YAS were primarily female (71%), Caucasian (78%), college educated (65%), and generated the SCP without assistance (76%). YAS reported satisfaction with content (93%) and shared content with providers (71%). A higher proportion of YAS than AS were male (29% vs. 17%, p < 0.001), lived internationally (23% vs. 17%, p = 0.003), and endorsed oncologist-led survivorship care (47% vs. 41%, p = 0.001). YAS reported concerns about neurocognitive performance (56%) and fatigue (50%). Overall, YAS reported equivalent or fewer late effects than AS across all domains. CONCLUSIONS: YAS report high satisfaction with the online SCP, as well as a high symptom burden, although the latter were reported less than for AS. PMID- 29570982 TI - Using ramp-incremental VO2 responses for constant-intensity exercise selection. AB - Despite compelling evidence to the contrary, the view that oxygen uptake (VO2) increases linearly with exercise intensity (e.g., power output, speed) until reaching its maximum persists within the exercise physiology literature. This viewpoint implies that the VO2 response at any constant intensity is predictable from a ramp-incremental exercise test. However, the VO2 versus task-specific exercise intensity relationship constructed from ramp-incremental versus constant intensity exercise are not equivalent preventing the use of VO2 responses from 1 domain to predict those of the other. Still, this "linear" translational framework continues to be adopted as the guiding principle for aerobic exercise prescription and there remains in the sport science literature a lack of understanding of how to interpret VO2 responses to ramp-incremental exercise and how to use those data to assign task-specific constant-intensity exercise. The objectives of this paper are to (i) review the factors that disassociate the VO2 versus exercise intensity relationship between ramp-incremental and constant intensity exercise paradigms; (ii) identify when it is appropriate (or not) to use ramp VO2 responses to accurately assign constant-intensity exercise; and (iii) illustrate the technical and theoretical challenges with prescribing constant-intensity exercise solely on information acquired from ramp-incremental tests. Actual VO2 data collected during cycling exercise and VO2 kinetics modelling are presented to exemplify these concepts. Possible solutions to overcome these challenges are also presented to inform on appropriate intensity selection for individual-specific aerobic exercise prescription in both research and practical settings. PMID- 29570984 TI - Effects of the Green Tea Polyphenol Epigallocatechin-3-Gallate on Glioma: A Critical Evaluation of the Literature. AB - The review discusses the effects of Epigallocatechin-3-gallate Gallate (EGCG) on glioma as a basis for future research on clinical application of EGCG. Epidemiological studies on the effects of green tea or EGCG on the risk of glioma is inconclusive due to the limited number of studies, the inclusion of all tea types in these studies, and the focus on caffeine rather than EGCG. In vivo experiments using EGCG monotherapy are inconclusive. Nevertheless, EGCG induces cell death, prevents cellular proliferation, and limits invasion in multiple glioma cell lines. Furthermore, EGCG enhances the efficacy of anti-glioma therapies, including irradiation, temozolomide, carmustine, cisplatin, tamoxifen, and TNF-related apoptosis-inducing ligand, but reduces the effect of bortezomib. Pro-drugs, co-treatment, and encapsulation are being investigated to enhance clinical applicability of EGCG. Mechanisms of actions of EGCG have been partly elucidated. EGCG has both anti-oxidant and oxidant properties. EGCG inhibits pro survival proteins, such as telomerase, survivin, GRP78, PEA15, and P-gp. EGCG inhibits signaling of PDGFR, IGF-1R, and 67LR. EGCG reduces invasiveness of cancer cells by inhibiting the activities of various metalloproteinases, cytokines, and chemokines. Last, EGCG inhibits some NADPH-producing enzymes, thus disturbing redox status and metabolism of glioma cells. In conclusion, EGCG may be a suitable adjuvant to potentiate anti-glioma therapies. PMID- 29570985 TI - Processed Meat and Risk of Renal Cell and Bladder Cancers. AB - We assessed the association of processed meat intake with the risk of renal cell carcinoma (RCC) and bladder cancer. We used data from two Italian hospital-based case-control studies, including 1,115 RCC cases and 2,582 controls, and 1,417 bladder cancer cases and 1,732 controls. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) with unconditional logistic regression models, adjusted for major confounders. The median consumption of processed meat in cases and controls was around 2 portions/week (50 g/portion). The ORs for a daily 10 g increment of processed meat was 0.89 (95% CI 0.84-0.94) for RCC and 1.00 (95% CI 0.94-1.06) for bladder cancer. The OR for the highest vs. the lowest consumption was 0.80 (95% CI 0.66-0.96) for RCC and 0.98 (95% CI 0.80-1.21) for bladder cancer. The ORs were consistent in strata of various covariates. For bladder cancer, however, a significant 23% excess risk was found in women (95% CI 1.03 1.47) for a daily increase of 10 g, significantly heterogeneous from the risk recorded in men (OR 0.96, 95% CI 0.90-1.02). The inconsistent results between men and women and the absence of association in both sexes combined indicate that the apparent association between processed meat and bladder cancer in women is unlikely to be causal. PMID- 29570987 TI - Role of EGCG in Containing the Progression of Lung Tumorigenesis - A Multistage Targeting Approach. AB - Lung cancer is a prominent form among various types of cancers, irrespective of the sex worldwide. Treatment of lung cancer involves the intensive phase of chemotherapy/radiotherapy which is associated with high rate of adverse events. There is a need of safe and reliable treatment/adjunctive therapy to apprehend the cancer by reducing the undesirable outcome of primary therapy. Epigallocatechin-3-gallate (EGCG), which is a potent antioxidant and anticancer compound extracted from the plant camellia sinensis has proved to be a novel agent to control or reduce lung tumorigenesis by affecting the signaling molecules of cell cycle regulation and apoptotic pathways. In vitro studies have revealed that EGCG can contain carcinogenesis by altering the molecules involved in multiple signal transduction pathways like ERK, VEGF, COX2, NEAT, Ras-GTPase, and kinases. The animal studies have also demonstrated effectiveness of EGCG by inhibiting various molecular pathways which include AKT, NFkB, MAPK, Bcl/Bax, DNMT1, and HIF-1alpha. Various attempts have been made to see the adjunctive role of EGCG in human lung cancer. Phase I/II clinical studies have recommended that EGCG is quite safe and effective in providing protection against cancer. In this review, we will discuss the role of EGCG and its molecular mechanisms in lung carcinogenesis. PMID- 29570986 TI - AMP-activated Protein Kinase Phosphorylation of Angiotensin-Converting Enzyme 2 in Endothelium Mitigates Pulmonary Hypertension. AB - RATIONALE: Endothelial dysfunction plays an integral role in pulmonary hypertension (PH). AMPK (AMP-activated protein kinase) and ACE2 (angiotensin converting enzyme 2) are crucial in endothelial homeostasis. The mechanism by which AMPK regulates ACE2 in the pulmonary endothelium and its protective role in PH remain elusive. OBJECTIVES: We investigated the role of AMPK phosphorylation of ACE2 Ser680 in ACE2 stability and deciphered the functional consequences of this post-translational modification of ACE2 in endothelial homeostasis and PH. METHODS: Bioinformatics prediction, kinase assay, and antibody against phospho ACE2 Ser680 (p-ACE2 S680) were used to investigate AMPK phosphorylation of ACE2 Ser680 in endothelial cells. Using CRISPR-Cas9 genomic editing, we created gain of-function ACE2 S680D knock-in and loss-of-function ACE2 knockout (ACE2-/-) mouse lines to address the involvement of p-ACE2 S680 and ACE2 in PH. The AMPK-p ACE2 S680 axis was also validated in lung tissue from humans with idiopathic pulmonary arterial hypertension. MEASUREMENTS AND MAIN RESULTS: Phosphorylation of ACE2 by AMPK enhanced the stability of ACE2, which increased Ang (angiotensin) 1-7 and endothelial nitric oxide synthase-derived NO bioavailability. ACE2 S680D knock-in mice were resistant to PH as compared with wild-type littermates. In contrast, ACE2-knockout mice exacerbated PH, a similar phenotype found in mice with endothelial cell-specific deletion of AMPKalpha2. Consistently, the concentrations of phosphorylated AMPK, p-ACE2 S680, and ACE2 were decreased in human lungs with idiopathic pulmonary arterial hypertension. CONCLUSIONS: Impaired phosphorylation of ACE2 Ser680 by AMPK in pulmonary endothelium leads to a labile ACE2 and hence is associated with the pathogenesis of PH. Thus, AMPK regulation of the vasoprotective ACE2 is a potential target for PH treatment. PMID- 29570988 TI - Frailty and Comorbidities Among Survivors of Adolescent and Young Adult Cancer: A Cross-Sectional Examination of a Hospital-Based Survivorship Cohort. AB - PURPOSE: Cancer survivors are at increased risk for the early development of age related chronic medical conditions compared with peers without a history of cancer; however, little is known regarding the burden of these conditions among survivors of adolescent and young adult (AYA) cancers. In response, we sought to determine the prevalence of specific comorbidities and frailty among AYAs (15-39 years old at diagnosis) enrolled in a cancer survivorship cohort. METHODS: Using a cross-sectional survey of a tertiary medical center-based cancer survivorship cohort, we determined the prevalence of specific comorbidities and frailty using the survey-based FRAIL assessment. In separate models adjusting for age, we estimated prevalence ratios (PRs) for the associations between patient characteristics and (1) any comorbidity and (2) frailty or prefrailty using log binomial models. RESULTS: We identified 271 AYA cancer survivors, most of whom were 30-39 years old at survey (57%). A majority of survivors (n = 163, 60%) reported having at least one comorbidity with the most common being depression (28%), anxiety (27%), asthma (17%), high cholesterol (15%), and hypertension (15%). Of the 184 AYA survivors at least 1 year from cancer diagnosis, 19 (10%) were classified as frail and 39 (21%) as prefrail. Survivors who were smokers (PR 2.0, 95% confidence interval [CI]: 1.16-3.56); obese (PR 1.7, 95% CI: 1.10-2.55); uninsured (PR 2.7, 95% CI: 1.63-4.59); or who reported comorbid depression or anxiety (PR 2.4, 95% CI: 1.51-3.67) were more likely to be frail or prefrail. CONCLUSIONS: The prevalence of frailty and comorbidities is high among AYA cancer survivors suggestive of accelerated aging. PMID- 29570990 TI - There Will Be Blood Tests.

Having such a model will open new dimensions in biological research and accelerate healthcare advancements.

Here, we present a vision for creation of a spatiotemporal multi-scale model of the pancreatic beta-cell, a relevant target for understanding and modulating the pathogenesis of diabetes. PMID- 29570992 TI - Amino Acid Restriction Triggers Angiogenesis via GCN2/ATF4 Regulation of VEGF and H2S Production. AB - Angiogenesis, the formation of new blood vessels by endothelial cells (ECs), is an adaptive response to oxygen/nutrient deprivation orchestrated by vascular endothelial growth factor (VEGF) upon ischemia or exercise. Hypoxia is the best understood trigger of VEGF expression via the transcription factor HIF1alpha. Nutrient deprivation is inseparable from hypoxia during ischemia, yet its role in angiogenesis is poorly characterized. Here, we identified sulfur amino acid restriction as a proangiogenic trigger, promoting increased VEGF expression, migration and sprouting in ECs in vitro, and increased capillary density in mouse skeletal muscle in vivo via the GCN2/ATF4 amino acid starvation response pathway independent of hypoxia or HIF1alpha. We also identified a requirement for cystathionine-gamma-lyase in VEGF-dependent angiogenesis via increased hydrogen sulfide (H2S) production. H2S mediated its proangiogenic effects in part by inhibiting mitochondrial electron transport and oxidative phosphorylation, resulting in increased glucose uptake and glycolytic ATP production. PMID- 29570993 TI - A Neural Circuit for the Suppression of Pain by a Competing Need State. AB - Hunger and pain are two competing signals that individuals must resolve to ensure survival. However, the neural processes that prioritize conflicting survival needs are poorly understood. We discovered that hunger attenuates behavioral responses and affective properties of inflammatory pain without altering acute nociceptive responses. This effect is centrally controlled, as activity in hunger sensitive agouti-related protein (AgRP)-expressing neurons abrogates inflammatory pain. Systematic analysis of AgRP projection subpopulations revealed that the neural processing of hunger and inflammatory pain converge in the hindbrain parabrachial nucleus (PBN). Strikingly, activity in AgRP -> PBN neurons blocked the behavioral response to inflammatory pain as effectively as hunger or analgesics. The anti-nociceptive effect of hunger is mediated by neuropeptide Y (NPY) signaling in the PBN. By investigating the intersection between hunger and pain, we have identified a neural circuit that mediates competing survival needs and uncovered NPY Y1 receptor signaling in the PBN as a target for pain suppression.

AB - H2S is an endogenous gasotransmitter that plays an important role in physiological conditions. In this issue, Das et al. provide evidence that SIRT1 dependent angiogenesis is augmented by H2S-findings reinforced by Longchamp et al., who demonstrate that H2S-dependent angiogenesis is triggered by amino acid deprivation. PMID- 29570999 TI - Impairment of an Endothelial NAD+-H2S Signaling Network Is a Reversible Cause of Vascular Aging. AB - A decline in capillary density and blood flow with age is a major cause of mortality and morbidity. Understanding why this occurs is key to future gains in human health. NAD precursors reverse aspects of aging, in part, by activating sirtuin deacylases (SIRT1-SIRT7) that mediate the benefits of exercise and dietary restriction (DR). We show that SIRT1 in endothelial cells is a key mediator of pro-angiogenic signals secreted from myocytes. Treatment of mice with the NAD+ booster nicotinamide mononucleotide (NMN) improves blood flow and increases endurance in elderly mice by promoting SIRT1-dependent increases in capillary density, an effect augmented by exercise or increasing the levels of hydrogen sulfide (H2S), a DR mimetic and regulator of endothelial NAD+ levels. These findings have implications for improving blood flow to organs and tissues, increasing human performance, and reestablishing a virtuous cycle of mobility in the elderly.

In humans and other mammals, these small RNAs help sculpt the expression of most mRNAs. This article reviews advances in our understanding of the defining features of metazoan miRNAs and their biogenesis, genomics, and evolution. It then reviews how metazoan miRNAs are regulated, how they recognize and cause repression of their targets, and the biological functions of this repression, with a compilation of knockout phenotypes that shows that important biological functions have been identified for most of the broadly conserved miRNAs of mammals. PMID- 29571001 TI - Photobiomodulation reduces gliosis in the basal ganglia of aged mice. AB - This study explored the effects of long-term photobiomodulation (PBM) on the glial and neuronal organization in the striatum of aged mice. Mice aged 12 months were pretreated with PBM (670 nm) for 20 minutes per day, commencing at 5 months old and continued for 8 months. We had 2 control groups, young at 3 months and aged at 12 months old; these mice received no treatment. Brains were aldehyde fixed and processed for immunohistochemistry with various glial and neuronal markers. We found a clear reduction in glial cell number, both astrocytes and microglia, in the striatum after PBM in aged mice. By contrast, the number of 2 types of striatal interneurons (parvalbumin+ and encephalopsin+), together with the density of striatal dopaminergic terminals (and their midbrain cell bodies), remained unchanged after such treatment. In summary, our results indicated that long-term PBM had beneficial effects on the aging striatum by reducing glial cell number; and furthermore, that this treatment did not have any deleterious effects on the neurons and terminations in this nucleus. PMID- 29571002 TI - Multiuser virtual worlds in healthcare education: A systematic review. AB - BACKGROUND: The use of multiuser virtual worlds (MUVWs) for collaborative learning has generated interest among healthcare educators. Published evidence to support its use is growing, but none has synthesized the evidence to guide future work. OBJECTIVE: This study sought to provide a comprehensive and systematic evaluation of MUVWs in healthcare education. DESIGN: A systematic review METHODS: A systematic search of five databases including CINAHL, Cochrane library, EMBASE, PubMed, and Scopus, was conducted from inception up to January 2017. Two independent researchers selected studies that met the inclusion criteria and assessed for methodological quality using the Medical Education Research Study Quality Instrument (MERSQI). A total of 18 studies were reviewed and their data were synthesized narratively using a 3-P model (presage-process-product). RESULTS: Average scores in the MERSQI for methodological quality are 10/18, which is modest. A rally by the government or professional bodies towards more collaborative working among healthcare professionals is a key driver behind implementing MUVWs. Funding is important for its development and evaluation. Team training in acute care and communication training were the most frequent learning objectives, and predominant learning activities include practice on simulation scenario and debriefing. Two-thirds of the studies did not explain their theoretical framework that underpinned their design and implementation of MUVWs. While MUVWs in healthcare education is generally well-received, learning outcomes remain inconclusive. CONCLUSION: Despite a growth of studies on the use of MUVW in healthcare education, there is a need for more understanding of the application of theories to inform the learning activities. Therefore, we suggest educators to incorporate a theoretical model to explain the learning processes behind MUVWs. To improve the quality of evidence, we call for researchers to employ a more rigorous and broader approach to evaluation that explicates longer term outcomes, including cost benefit analyses. PMID- 29571003 TI - Elucidating the substrate specificities of acyl-lipid thioesterases from diverse plant taxa. AB - Acyl-ACP thioesterase enzymes, which cleave fatty acyl thioester bonds to release free fatty acids, contribute to much of the fatty acid diversity in plants. In Arabidopsis thaliana, a family of four single hot-dog fold domain, plastid localized acyl-lipid thioesterases (AtALT1-4) generate medium-chain (C6-C14) fatty and beta-keto fatty acids as secondary metabolites. These volatile products may serve to attract insect pollinators or deter predatory insects. Homologs of AtALT1-4 are present in all plant taxa, but are nearly all uncharacterized. Despite high sequence identity, AtALT1-4 generate different lipid products, suggesting that ALT homologs in other plants also have highly varied activities. We investigated the catalytic diversity of ALT-like thioesterases by screening the substrate specificities of 15 ALT homologs from monocots, eudicots, a lycophyte, a green microalga, and the ancient gymnosperm Gingko biloba, via expression in Escherichia coli. Overall, these enzymes had highly varied substrate preferences compared to one another and to AtALT1-4, and could be classified into four catalytic groups comprising members from diverse taxa. Group 1 ALTs primarily generated 14:1 beta-keto fatty acids, Group 2 ALTs produced 6-10 carbon fatty/beta-keto fatty acids, Group 3 ALTs predominantly produced 12-14 carbon fatty acids, and Group 4 ALTs mainly generated 16 carbon fatty acids. Enzymes in each group differed significantly in the quantities of lipids and types of minor products they generated in E. coli. Medium-chain fatty acids are used to manufacture insecticides, pharmaceuticals, and biofuels, and ALT-like proteins are ideal candidates for metabolic engineering to produce specific fatty acids in significant quantities. PMID- 29571004 TI - Signal transduction in artichoke [Cynara cardunculus L. subsp. scolymus (L.) Hayek] callus and cell suspension cultures under nutritional stress. AB - Stimulated production of secondary phenolic metabolites and proline was studied by using cell cultures of artichoke [Cynara cardunculus L. subsp. scolymus (L.) Hayek] submitted to nutritional stress. Artichoke cell cultures accumulated phenolic secondary metabolites in a pattern similar to that seen in artichoke leaves and heads (capitula). This paper shows that both callus and cell suspension cultures under nutritional stress accumulated phenolic compounds and proline, at the same time their biomass production was negatively affected by nutrient deficiency. The results obtained strongly suggest that plant tissues respond to nutrient deprivation by a defensive costly mechanism, which determines the establishment of a mechanism of trade-off between growth and adaptive response. Furthermore, the results of this research suggest that perception of abiotic stress and increased phenolic metabolites are linked by a sequence of biochemical processes that also involves the intracellular free proline and the oxidative pentose phosphate pathway. The main conclusion of this paper is that, once calli and cell suspension cultures respond to nutrient deficiency, in acclimated cells the establishment of a negative correlation between primary metabolism (growth) and secondary metabolism (defence compounds) is observed. PMID- 29571005 TI - Attentional control deficits in social anxiety: Investigating inhibition and shifting functions using a mixed antisaccade paradigm. AB - BACKGROUND AND OBJECTIVES: Attentional control has recently been assumed to play a critical role in the generation and maintenance of threat-related attentional bias and social anxiety. The present study aimed to investigate whether socially anxious (SA) individuals show impairments in attentional control functions, particularly in inhibition and shifting. METHODS: Forty-two SA and 41 non-anxious (NA) participants completed a mixed antisaccade task, a variant of the antisaccade task that is used to investigate inhibition as well as shifting functions. RESULTS: The results showed that, overall, SA participants had longer antisaccade latencies than NA participants, but the two groups did not differ in their antisaccade error rates. Moreover, in the single-task block, SA participants had longer latencies than NA participants for antisaccade but not prosaccade trials. In the mixed-task block, the SA participants had longer latencies than the NA participants for both task types. The two groups did not differ in their latency switch costs in the mixed-task blocks. LIMITATIONS: First, this study was conducted using a non-clinical sample of undergraduate students. Second, the antisaccade task measures primarily oculomotor inhibition. Third, this study did not include the measure of state anxiety to rule out the effects of state anxiety on the present findings. CONCLUSIONS: This study suggests that SA individuals demonstrate diminished efficiency of inhibition function but show no significant impairment of shifting function. However, in the mixed-task condition, SA individuals may exhibit an overall reduction in processing efficiency due to the higher task difficulty. PMID- 29571006 TI - Non-metric multidimensional scaling and human risks of heavy metal concentrations in wild marine organisms from the Maowei Sea, the Beibu Gulf, South China Sea. AB - We investigated heavy metal concentrations in wild marine organisms from Maowei Sea, a significant gulf of low-latitude developing regions of the Beibu Gulf, South China Sea. Twenty species, comprising fish, cephalopods, and crustaceans were collected and analyzed for heavy metals. Heavy metal levels (mg/kg, wet weight) in the aquatic organism samples were: 0.003-1.800 for Cd, 0.02-0.14 for Pb, 0.10-0.63 for Cr, 0.20-77.50 for Cu, 9.50-64.60 for Zn, 0.006-0.066 for Hg, and 0.10-1.50 for As. Non-metric multidimensional scaling coupled with cluster analysis revealed two groupings that mainly resulted from different species of the metals in marine organisms. The highest concentrations of Cd, Pb, Cr, Ni, Cu, Zn, Hg, and As were found in species of cephalopods. Health risk assessment based on the target hazard quotients (THQ) and total THQ indicated no significant adverse health effects from consumption of marine organisms. PMID- 29571007 TI - Time-restricted feeding influences immune responses without compromising muscle performance in older men. AB - OBJECTIVE: This study examined the effect of 12 wk of time-restricted feeding (TRF) on complete blood cell counts, natural killer cells, and muscle performance in 20- and 50-year-old men. METHODS: Forty active and healthy participants were randomly divided into young experimental, young control, aged experimental, and aged control group. Experimental groups participated in TRF. Before (P1) and after (P2) TRF, participants performed a maximal exercise test to quantify muscle power. Resting venous blood samples were collected for blood count calculation. RESULTS: No changes were identified in muscle power in all groups after TRF (P > 0.05). At P1, red cells, hemoglobin, and hematocrit were significantly higher in young participants compared with elderly participants (P < 0.05). At P2, this age effect was not found in red cells between the young experimental group and the aged experimental group (P > 0.05). At P1, white blood cells and neutrophils were significantly higher in young participants compared with elderly participants (P < 0.05). At P2, only neutrophils decreased significantly (P < 0.05) in experimental groups without significant (P > 0.05) difference among them. Lymphocytes decreased significantly in the aged experimental group at P2 (P < 0.05), whereas NKCD16+ and NKCD56+ decreased significantly in experimental groups at P2 (P < 0.05). TRF had no effect on CD3, CD4+, and CD8+ levels (P > 0.05). CONCLUSION: TRF decreases hematocrit, total white blood cells, lymphocytes, and neutrophils in young and older men. TRF may be effective in preventing inflammation by decreasing natural killer cells. As such, TRF could be a lifestyle strategy to reduce systemic low-grade inflammation and age-related chronic diseases linked to immunosenescence, without compromising physical performance. PMID- 29571009 TI - Lifelong calorie restriction affects indicators of colonic health in aging C57Bl/6J mice. AB - Diminished colonic health is associated with various age-related pathologies. Calorie restriction (CR) is an effective strategy to increase healthy lifespan, although underlying mechanisms are not fully elucidated. Here, we report the effects of lifelong CR on indicators of colonic health in aging C57Bl/6J mice. Compared to an ad libitum control and moderate-fat diet, 30% energy reduction was associated with attenuated immune- and inflammation-related gene expression in the colon. Furthermore, expression of genes involved in lipid metabolism was higher upon CR, which may point towards efficient regulation of energy metabolism. The relative abundance of bacteria considered beneficial to colonic health, such as Bifidobacterium and Lactobacillus, increased in the mice exposed to CR for 28 months as compared to the other diet groups. We found lower plasma levels of interleukin-6 and lower levels of various metabolites, among which are bile acids, in the colonic luminal content of CR-exposed mice as compared to the other diet groups. Switching from CR to an ad libitum moderate-fat diet at old age (24 months) revealed remarkable phenotypic plasticity in terms of gene expression, microbiota composition and metabolite levels, although expression of a subset of genes remained CR-associated. This study demonstrated in a comprehensive way that CR affects indicators of colonic health in aging mice. Our findings provide unique leads for further studies that need to address optimal and feasible strategies for prolonged energy deprivation, which may contribute to healthy aging. PMID- 29571008 TI - Grape proanthocyanidin-induced intestinal bloom of Akkermansia muciniphila is dependent on its baseline abundance and precedes activation of host genes related to metabolic health. AB - We previously showed that C57BL/6J mice fed high-fat diet (HFD) supplemented with 1% grape polyphenols (GP) for 12 weeks developed a bloom of Akkermansia muciniphila with attenuated metabolic syndrome symptoms. Here we investigated early timing of GP-induced effects and the responsible class of grape polyphenols. Mice were fed HFD, low-fat diet (LFD) or formulations supplemented with GP (HFD-GP, LFD-GP) for 14 days. Mice fed HFD-GP, but not LFD-GP, showed improved oral glucose tolerance compared to controls. A. muciniphila bloom occurred earlier in mice fed LFD-GP than HFD-GP; however, timing was dependent on baseline A. muciniphila levels rather than dietary fat. Mice gavaged for 10 days with GP extract (GPE) or grape proanthocyanidins (PACs), each delivering 360 mg PACs/kg body weight, induced a bloom of fecal and cecal A. muciniphila, the rate of which depended on initial A. muciniphila abundance. Grape PACs were sufficient to induce a bloom of A. muciniphila independent of specific intestinal gene expression changes. Gut microbial community analysis and in vitro inhibition of A. muciniphila by GPE or PACs suggest that the A. muciniphila bloom in vivo occurs via indirect mechanisms. PMID- 29571010 TI - Fecal microbiome composition and stability in 4- to 8-year old children is associated with dietary patterns and nutrient intake. AB - How long-term dietary intake shapes microbiota composition and stability in young children is poorly understood. Herein, the temporal variability in stool microbiota composition in relation to habitual dietary patterns of 4- to 8-year old children (n=22) was investigated. Fecal samples were collected at baseline, 6 weeks and 6 months. Bacterial composition and volatile fatty acids were assessed by 16S rRNA sequencing and gas-chromatography, respectively. Nutrient intake was assessed using 3-day food diaries and dietary patterns were empirically derived from a food frequency questionnaire. Using a factor loading of >0.45 for a food group to be a major contributor to the overall dietary pattern, two dietary patterns were found to be associated with distinct microbiome composition. Dietary Pattern 1 (DP1), characterized by intake of fish, protein foods, refined carbohydrates, vegetables, fruit, juice and sweetened beverages, kid's meals and snacks and sweets, was associated with higher relative abundance of Bacteroidetes, Bacteroides and Ruminococcus and lower abundance of Bifidobacterium, Prevotella, Blautia and Roseburia. Dietary Pattern 2 (DP2), characterized by intake of grains, dairy and legumes, nuts and seeds, was associated with higher relative abundance of Cyanobacteria and Phascolarctobacterium and lower abundance of Dorea and Eubacterium. Fruit and starchy foods were present in both patterns, but were more associated with DP1 and DP2, respectively. Temporal stability of microbiota over a 6-month period was associated with baseline dietary patterns. Understanding how dietary intake contributes to microbiota composition and stability in early life in important for dietary recommendations and designing clinical interventions for microbiota associated diseases.

AB - Many jurisdictions around the world have implemented laws to require a minimum distance when motor vehicles pass cyclists, but research into the factors influencing passing distances has produced inconsistent results, indicating the need for future research. This study examined the factors influencing motorists' compliance with a legislated bicycle passing distance rule in Queensland, Australia. Unlike the earlier studies, which used volunteer riders to record passing events, this study used a naturalistic study design to record passing events where none of the motorists or the cyclists were aware of being studied. As a result, this study captured the 'true' driving and riding behaviours during passing events. The likelihood of non-compliance was greater on higher (70-80 km/h speed limits) and lower (40 km/h) speed roads than 60 km/h roads, at curved road sections, and on roads with narrower traffic lanes. Rider characteristics (age, gender, helmet status, type of clothing, type of bicycle, and individual or group riding) had no statistically significant association with compliance status. The findings indicate that efforts to improve cyclist safety during overtaking events should focus on non-rider related factors, such as roadway infrastructure characteristics. PMID- 29571012 TI - Have pedestrian subsystem tests improved passenger car front shape? AB - Subsystem impactor tests are the main approaches for evaluation of safety performance of vehicle front design for pedestrian protection in legislative regulations. However, the main aspects of vehicle safety for pedestrians are shape and stiffness, and though it is clear that subsystem impact tests encourage lower vehicle front stiffness, it is unclear whether they promote improved vehicle front shapes for pedestrian protection. The purpose of this paper is therefore to investigate the effects of European pedestrian safety regulations on passenger car front shape and pedestrian injury risk using recent German In-Depth Accident Study (GIDAS) pedestrian collision data and numerical simulations. Firstly, a sample of 579 pedestrian collision cases involving 190 different car models between 2000-2015 extracted from the GIDAS was used to compare front-end shapes of passenger cars manufactured before and after the legislative pedestrian safety regulations were introduced in Europe. The focus was on changes in passenger car front shape and differences in pedestrian AIS2+ (Abbreviated Injury Scale at least level 2) leg, pelvis/femur and head injury risk observed in collisions. Multi-body simulations were also used to assess changes in vehicle aggressivity due to the observed changes in vehicle shape. The results show that newer passenger cars tend to have a flatter and wider bumper, higher bonnet leading edge, shorter and steeper bonnet and a shallower windscreen. Both the collision data and the numerical simulations indicate that newer passenger car front bumper designs are significantly safer for pedestrians' legs. However, the results also show that the higher bonnet leading edge in newer passenger cars is poor for pedestrian pelvis/femur protection, even though newer cars show an obviously lower AIS2+ injury risk to younger pedestrians in collisions. Newer cars have a lower AIS2+ head injury risk for pedestrians in collisions, but the numerical analysis indicate that this is not likely due to shape changes in passenger car fronts. Overall, the introduction of pedestrian safety regulations has resulted in reductions in pedestrian injury risk, but further benefits would accrue from tests which promote a lower bonnet leading edge. The influence of vehicle shape on pedestrian head injury risk remains unclear. PMID- 29571013 TI - A ternary complex model of Sirtuin4-NAD+-Glutamate dehydrogenase. AB - Sirtuin4 (Sirt4) is one of the mammalian homologues of Silent information regulator 2 (Sir2), which promotes the longevity of yeast, C. elegans, fruit flies and mice. Sirt4 is localized in the mitochondria, where it contributes to preventing the development of cancers and ischemic heart disease through regulating energy metabolism. The ADP-ribosylation of glutamate dehydrogenase (GDH), which is catalyzed by Sirt4, downregulates the TCA cycle. However, this reaction mechanism is obscure, because the structure of Sirt4 is unknown. We here constructed structural models of Sirt4 by homology modeling and threading, and docked nicotinamide adenine dinucleotide+ (NAD+) to Sirt4. In addition, a partial GDH structure was docked to the Sirt4-NAD+ complex model. In the ternary complex model of Sirt4-NAD+-GDH, the acetylated lysine 171 of GDH is located close to NAD+. This suggests a possible mechanism underlying the ADP-ribosylation at cysteine 172, which may occur through a transient intermediate with ADP ribosylation at the acetylated lysine 171. These results may be useful in designing drugs for the treatment of cancers and ischemic heart disease. PMID- 29571014 TI - Sanguinarine inhibits epithelial ovarian cancer development via regulating long non-coding RNA CASC2-EIF4A3 axis and/or inhibiting NF-kappaB signaling or PI3K/AKT/mTOR pathway. AB - OBJECTIVE: This study aimed to investigate the antitumor effects and possible regulatory mechanisms of sanguinarine in epithelial ovarian cancer. MATERIAL AND METHODS: The effects of sanguinarine on the malignant behaviors of epithelial ovarian cancer SKOV3 cells and the expression of long non-coding RNA CASC2 were investigated. The expression of CASC2 and EIF4A3 in epithelial ovarian cancer tissues and cells were detected, and the potential mechanisms of sanguinarine were explored by investigating the interactions between CASC2 and EIF4A3. Furthermore, the regulatory relationship between sanguinarine and nuclear factor kappaB (NF-kappaB) signaling or PI3K/AKT/mTOR pathway was explored. RESULTS: Sanguinarine exhibited antitumor effects in SKOV3 cells by significantly inhibiting cell viability, migration and invasion and promoting cell apoptosis. Moreover, sanguinarine induced CASC2 expression and silencing of CASC2 reversed the effects of sanguinarine in epithelial ovarian cancer cells. CASC2 was significantly lowly expressed in ovarian cancer tissues and cells, while EIF4A3 was highly expressed. EIF4A3 was identified as a CASC2 binding protein. Knockdown of EIF4A3 reversed the effects of sanguinarine plus CASC2 silencing. Besides, sanguinarine markedly inhibited the activation of NF-kappaB signaling or PI3K/AKT/mTOR pathway, which was reversed by CASC2 silencing. And the effects of sanguinarine plus CASC2 silencing on the activation of these pathways were further reversed after knockdown of EIF4A3 at the same time. CONCLUSIONS: Our findings reveal that sanguinarine exhibits antitumor effects in epithelial ovarian cancer cells possible via regulating CASC2-EIF4A3 axis and/or inhibiting NF-kappaB signaling or PI3K/AKT/mTOR pathway. Sanguinarine may serve as a potential therapeutic reagent for epithelial ovarian cancer. PMID- 29571015 TI - Enhanced lipoxygenase/LTD4 signaling accounts for the exaggerated hypertensive and nephrotoxic effects of cyclosporine plus indomethacin in rats. AB - The combined use of cyclosporine (CSA) and nonsteroidal antiinflammatory drugs (NSAIDs) causes exaggerated rises in systolic blood pressure (SBP) and nephrotoxicity. We examined whether these influences relate to the arachidonate/5 lipoxygenase (LOX) pathway. Rats were treated with CSA (20 mg kg-1 day-1), indomethacin (5 mg kg-1 day-1), or their combination for 10 days. Changes in SBP and renal biochemical/histopathological characteristics along with leukotriene levels were determined in rats treated with or without LT receptor antagonists. CSA or indomethacin caused: (i) renal tubular atrophy and interstitial fibrosis, (ii) increases in serum creatinine, blood urea nitrogen (BUN), and renal LTD4, LTB4, TNF-alpha, TGF-beta1, and caspase-3, and (iii) decreases in renal PGE2 and total antioxidant capacity (TAC). SBP measured by tail-cuff plethysmography was increased by CSA but not indomethacin. These effects were mostly intensified in rats treated with CSA plus indomethacin. The co-treatment with montelukast (cysteinyl LT receptor blocker), but not ONO-4057 (LTB4 receptor blocker), ameliorated CSA/indomethacin-evoked hypertension, renal structural/biochemical deterioration, and LTD4 levels. Moreover, montelukast exhibited a greater capacity in reversing inflammatory, oxidative, apoptotic, and fibrotic abnormalities induced by CSA/indomethacin. Overall, lipoxygenase/LTD4 upregulation contributes to the exaggerated hypertension and nephrotoxicity caused by CSA/indomethacin. The therapeutic potential of cysteinyl LT receptor antagonism in rectifying CSA/NSAIDs-evoked anomalies is warranted. PMID- 29571016 TI - The role of nutrients in the pathogenesis and treatment of migraine headaches: Review. AB - OBJECTIVE: Migraine as a disabling neurovascular disease affects 6% of men and 18% of women worldwide. The deficiency of many nutrients including magnesium, niacin, riboflavin, cobalamin, coenzymes Q10, carnitine, alpha-lipoic acid and vitamin D is associated with migraine. Some researchers postulate that mitochondrial dysfunction and impaired antioxidant status can cause migraine. Also increase in homocysteine level can lead to migraine attacks; therefore, some Nutraceuticals play a vital role in migraine prevention. Thus, the aim of the current study was to review randomized controlled trials (RCT) assessing the effect of nutritional supplements on migraine patients. METHODS: English articles in the following databases were searched: MEDLINE, AMED, EMBASE and Cochrane Library. In this manuscript, RCTs published during 1990-2017 were reviewed. RESULTS: Evidences indicate that supplementation with magnesium, carnitine, riboflavin, niacin, CoQ10, vitamin D, Vitamin B12 and alpha lipoic acid have prophylactic and therapeutic effects on migraine patients. CONCLUSION: Due to the possible side effects of pharmacological drugs and drug addictions, the use of nutrient compounds alone or in combination with routine cures have been proposed. However, further constructive studies are required. PMID- 29571017 TI - Long noncoding RNA SNHG7 accelerates prostate cancer proliferation and cycle progression through cyclin D1 by sponging miR-503. AB - Increasing evidence has indicated the important roles of long non-coding RNAs (lncRNAs) in tumorigenesis and cellular progression, including prostate cancer. In this study, we aim to investigate the expression level of SNHG7 and its biological functions on prostate cancer cells. Results indicated that SNHG7 expression was significantly up-regulated in prostate cancer tissue and cell lines. Besides, the overexpression of SNHG7 was closely correlated with the poor prognosis. In vitro and in vivo, experiments demonstrated that SNHG7 knockdown markedly inhibited prostate cancer proliferation and cycle-related protein (CDK4, CDK6, Cyclin D1), induced cell cycle arrest at G0/G1 phase and suppressed tumor growth. Moreover, miR-503 was predicted by bioinformatics tools and validated using luciferase reporter assay to both directly inhibited SNHG7 and Cyclin D1 expression by targeting their RNA 3'-UTR. In conclusion, results present that SNHG7 regulates the cycle progression and acts as an oncogenic gene in the prostate cancer tumorigenesis via miR-503/Cyclin D1 pathway, revealing the vital role of lncRNA/miRNA/mRNA axis in prostate cancer carcinogenesis. PMID- 29571018 TI - Stem cell therapy in Asherman syndrome and thin endometrium: Stem cell- based therapy. AB - The endometrium is one of the essential components of the uterus. The endometrium of human is a complex and dynamic tissue, which undergoes periods of growth and turn over during any menstrual cycle. Stem cells are initially undifferentiated cells that display a wide range of differentiation potential with no distinct morphological features. Stem cell therapy method recently has become a novel procedure for treatment of tissue injury and fibrosis in response to damage. Currently, there is massive interest in stem cells as a novel treatment method for regenerative medicine and more specifically for the regeneration of human endometrium disorder like Asherman syndrome (AS) and thin endometrium. AS also known as intrauterine adhesion (IUA) is a uterine disorder with the aberrant creation of adhesions within the uterus and/or cervix. Patients with IUA are significantly associated with menstrual abnormalities and suffer from pelvic pain. In addition, IUA might prevent implantation of the blastocyst, impair the blood supply to the uterus and early fetus, and finally result in the recurrent miscarriage or infertility in the AS patients. It has been evidenced that the transplantation of different stem cells with a diverse source in the endometrial zone had effects on endometrium such as declined the fibrotic area, an elevated number of glands, stimulated angiogenesis, the enhanced thickness of the endometrium, better formed tissue construction, protected gestation, and improved pregnancy rate. This study presents a summary of the investigations that indicate the key role of stem cell therapy in regeneration and renovation of defective parts. PMID- 29571019 TI - Involvement of estrogen receptors in silibinin protection of pancreatic beta cells from TNFalpha- or IL-1beta-induced cytotoxicity. AB - Silibinin is a polyphenolic flavonoid that exhibits anticarcinogenic, anti inflammatory and cytoprotective effects. The effect of silibinin on pancreatic islet beta-cell is yet largely unknown in spite of well documented hepatoprotective effects. Protecting the functional insulin-producing beta-cells in the pancreas is a major therapeutic challenge in the patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM). This study reports the effect of silibinin on the rat pancreatic beta-cell line, INS-1, damaged with pro inflammatory cytokine, TNFalpha or IL-1beta. Exposure to TNFalpha or IL-1beta for 48 h caused INS-1 cells to reduce the production of insulin as well as cell viability. These actions of TNFalpha or IL-1beta are associated with suppression of the expression of estrogen receptors (ERs). Further study revealed that silibinin protected the suppression in the expression of both ERalpha and ERbeta that were involved in insulin synthesis and release, respectively. Furthermore, evidence is obtained that silibinin may impede the loss of critical INS-1 cells by promoting autophagy and preventing apoptosis. Direct cytoprotective effects of silibinin on INS-1 cells suggest that silibinin may be therapeutically beneficial for diabetes. PMID- 29571021 TI - Linalyl acetate prevents olmesartan-induced intestinal hypermotility mediated by interference of the sympathetic inhibitory pathway in hypertensive rat. AB - Olmesartan-associated enteropathy (OAE) is a life-threatening pathological condition, but its underlying mechanisms have not been elucidated. Although intestinal hypermotility is frequently accompanied by chronic diarrhea, there have been no studies of olmesartan-induced hypermotility. Intestinal motility should be well regulated by the enteric nervous system, but degeneration of enteric neurons has been reported in patients with chronic diarrheal diseases, such as irritable bowel syndrome, suggesting a connection between OAE and intestinal hypermotility. In this study, interference with this inhibitory pathway was analyzed in a model of olmesartan-induced intestinal hypermotility (OIH) in rats with nicotine-induced hypertension exposed to chronic immobilizing stress. The effects of the potent inhibitory neurotransmitters norepinephrine (NE) and sodium nitroprusside (SNP), which act via different pathways, were assessed ex vivo, with only NE-modulated frequency and amplitude of spontaneous contractions found to be elevated in OIH rat jejunum. Clinical symptoms frequent in OAE, including atrophy of the intestinal epithelium and weight loss, were observed in these rats. Interestingly, olmesartan significantly elevated heart rate while lowering blood pressure in OIH rats. These abnormal conditions were prevented by adding linalyl acetate (LA), while the blood pressure-lowering effects of olmesartan were maintained. These findings suggest that olmesartan induces intestinal hypermotility by interfering with the sympathetic inhibitory pathway, and reduces epithelial cell size or body weight in hypertensive rats. As LA prevented these effects, combination treatment with olmesartan plus LA may provide better antihypertensive efficacy without inducing OAE. PMID- 29571020 TI - Experimental diabetes induced by streptozotocin in the desert gerbil, Gerbillus gerbillus, and the effects of short-term 20-hydroxyecdysone administration. AB - The present work was aimed at studying the effects of streptozotocin (STZ; 130 mg/kg) in the desert gerbil, Gerbillus gerbillus, and at evaluating the impact of the short-term administration of 20-hydroxyecdysone (20E; 5 mg/kg). We observed that administration of streptozotocin caused a significant increase in plasmatic glucose and a decrease in insulin levels. The plasma lipid profile and liver glycogen content were also altered. The activities of antioxidant enzymes and malondialdehyde (MDA) levels were increased in the pancreatic tissue of STZ treated gerbils. Moreover, histopathological and immunohistochemical analysis showed degenerative damage in the pancreas with a decline in the percentage area of beta-cells. Treatment of STZ-treated gerbils with 20E counteracted metabolic disorders and reduced lipid peroxidation. Histological and immunohistochemical studies showed moderate amelioration in the pancreatic structure. These findings indicate that streptozotocin administration induced experimental diabetes in gerbils and that short-term administration of 20E has beneficial effects in glucose homeostasis in STZ-treated gerbils suggesting that 20E may stimulate surviving beta-cells to release more insulin. PMID- 29571022 TI - TNF-alpha contributes to postmenopausal osteoporosis by synergistically promoting RANKL-induced osteoclast formation. AB - Previous studies showed that inflammatory cytokines promote osteoclast formation, characterized by the function of bone resorption. However, it remains unclear whether inflammatory factors contribute to osteoporosis syndrome in postmenopausal women. Here, we found that postmenopausal women with osteoporosis (PO) had increased levels of TNF-alpha, compared with those without osteoporosis. TNF-alpha is highly correlated with the RANK and estrogen levels in PO patients. in vitro, TNF-alpha synergistically promotes RANKL-induced osteoclast formation by activation of NF-kappaB and PI3K/Akt signaling. Moreover, inhibition of PI3K/Akt totally blocked the synergistic effects of TNF-alpha on NF-kappaB activation as well as osteoclast formation. Together, these results demonstrate that TNF-alpha synergistically promotes RANKL-induced osteoclasts formation through activation of PI3K/Akt signaling, which ultimately contributes to osteoporosis syndrome in postmenopausal women. PMID- 29571023 TI - Pretreatment with taurine prevented brain injury and exploratory behaviour associated with administration of anticancer drug cisplatin in rats. AB - The neurotoxicity associated with cisplatin treatment is one of the major side effects compromising the efficacy of the anti-cancer treatment. The present study investigated the possible protective effects of taurine, an intracellular amino acid, on cisplatin-induced brain injury and exploratory behaviour using five groups of ten female rats each. Group I received drinking water only. Group II orally received taurine alone at 200 mg/kg whereas Group III received cisplatin alone intraperitoneally at 10 mg/kg. Groups IV and V were treated with taurine at 100 and 200 mg/kg respectively for sixteen consecutive days and a single intraperitoneal injection of cisplatin on day 13 to induce neurotoxicity. Endpoint analyses using video-tracking software revealed that cisplatin administration alone caused neurobehavioral deficits evinced by marked decrease in the total distance travelled, average speed, total time mobile, total mobile episode, number of crossing and absolute turn angle. Furthermore, cisplatin alone significantly suppressed brain antioxidant defense mechanisms, elevated nitric oxide and lipid peroxidation levels whereas it increased acetylcholinesterase activity in the treated rats. However, rats pretreated with taurine exhibited significant improvement in behavioural performance and brain antioxidant status with concomitant decrease in acetylcholinesterase activity and oxidative stress indices when compared with cisplatin alone group. Histologically, taurine pretreatment prevented cisplatin-induced neuronal death in the cerebral and cerebellar cortices, caudo-putamen and hippocampus as well as abrogated cisplatin mediated decrease in the dendritic arborization and mean diameter of the somata of pyramidal neurons in the treated rats. In conclusion, taurine may be a possible protective supplement to reduce cisplatin-induced side-effects including neurotoxicity in patients undergoing cisplatin treatment. PMID- 29571024 TI - OzPythonPlex: An optimised forensic STR multiplex assay set for the Australasian carpet python (Morelia spilota). AB - Reptile species, and in particular snakes, are protected by national and international agreements yet are commonly handled illegally. To aid in the enforcement of such legislation, we report on the development of three 11-plex assays from the genome of the carpet python to type 24 loci of tetra-nucleotide and penta-nucleotide repeat motifs (pure, compound and complex included). The loci range in size between 70 and 550 bp. Seventeen of the loci are newly characterised with the inclusion of seven previously developed loci to facilitate cross-comparison with previous carpet python genotyping studies. Assays were optimised in accordance with human forensic profiling kits using one nanogram template DNA. Three loci are included in all three of the multiplex reactions as quality assurance markers, to ensure sample identity and genotyping accuracy is maintained across the three profiling assays. Allelic ladders have been developed for the three assays to ensure consistent and precise allele designation. A DNA reference database of allele frequencies is presented based on 249 samples collected from throughout the species native range. A small number of validation tests are conducted to demonstrate the utility of these multiplex assays. We suggest further appropriate validation tests that should be conducted prior to the application of the multiplex assays in criminal investigations involving carpet pythons. PMID- 29571025 TI - Assessing cadmium exposure risks of vegetables with plant uptake factor and soil property. AB - Plant uptake factors (PUFs) are of great importance in human cadmium (Cd) exposure risk assessment while it has been often treated in a generic way. We collected 1077 pairs of vegetable-soil samples from production fields to characterize Cd PUFs and demonstrated their utility in assessing Cd exposure risks to consumers of locally grown vegetables. The Cd PUFs varied with plant species and pH and organic matter content of soils. Once normalized PUFs against soil parameters, the PUFs distributions were log-normal in nature. In this manner, the PUFs were represented by definable probability distributions instead of a deterministic figure. The Cd exposure risks were then assessed using the normalized PUF based on the Monte Carlo simulation algorithm. Factors affecting the extent of Cd exposures were isolated through sensitivity analyses. Normalized PUF would illustrate the outcomes for uncontaminated and slightly contaminated soils. Among the vegetables, lettuce was potentially hazardous for residents due to its high Cd accumulation but low Zn concentration. To protect 95% of the lettuce production from causing excessive Cd exposure risks, pH of soils needed to be 5.9 and above. PMID- 29571026 TI - Green synthesis of tannin-hexamethylendiamine based adsorbents for efficient removal of Cr(VI). AB - Newly developed adsorbents, poly(tannin-hexamethylendiamine) (PTHA), were fabricated by varying the mole ratio of tannin (TA) and hexamethylendiamine (HA) under one-pot reaction. The specific forming process of the adsorbent which had undergone the transition from hydrogen bonds to covalent bonds was subsequently explored. Based on the efficiency of Cr(VI) removal from aqueous solution over all prepared adsorbents, the PTHA-4 (mole ratio of TA/HA = 1:12.5) exhibited an excellent adsorption behavior. Adsorption experiments affected by contact time and ionic strength have been conducted successively by PTHA-4, and the equilibrium was reached at 24 h. The kinetic data revealed that the adsorption was good agreement with pseudo-second order model and needed to undergo the rate controlling step. The maximum adsorption capacity was 283.29 mg/g at 30 degrees C, relying on the isothermal curve suitably described by Langmuir model. Furthermore, toxic Cr(VI) had been reduced to the low toxic Cr(III) during adsorption process. The structures and adsorption performance of adsorbent were confirmed by means of SEM, FT-IR, XPS etc. Thus, the cheap-sustainable adsorbents have a superior feature for Cr(VI)-wastewater purification in future. PMID- 29571027 TI - Construction of multifunctional MoSe2 hybrid towards the simultaneous improvements in fire safety and mechanical property of polymer. AB - Organic modification of MoSe2 sheets is firstly achieved by Atherton-Todd reaction, aiming at the acquisition of multifunctional MoSe2 hybrid. Simultaneous enhancements in fire safety and mechanical property of thermalplastic polyurethane (TPU) are obtained with the presence of this hybrid. Strong interfacial interactions between the functionalized MoSe2 sheets and TPU can be obtained, making more efficient load transfer from the weak polymer chains to the robust sheets. Besides, more coherent barrier network may be formed in polymer matrix, restraining the diffusion of decomposed fragments and reducing the supply for combustion fuel. Consequently, the decreases in heat release are observed for polymer composites. Notably, the releases of toxic gases, such as HCN and CO, are also suppressed by this barrier network, resulting in the reductions in fire toxicity. This work may open a new door for the functionalization of MoSe2 sheets and evoke significant developments in its promising applications. PMID- 29571028 TI - Automatic imitation effects are influenced by experience of synchronous action in children. AB - By their fourth year of life, children are expert imitators, but it is unclear how this ability develops. One approach suggests that certain types of experience might forge associations between the sensory and motor representations of an action that may facilitate imitation at a later time. Sensorimotor experience of this sort may occur when an infant's action is imitated by a caregiver or when socially synchronous action occurs. This learning approach, therefore, predicts that the strength of sensory-motor associations should depend on the frequency and quality of previous experience. Here, we tested this prediction by examining automatic imitation, that is, the tendency of an action stimulus to facilitate the performance of that action and interfere with the performance of an incompatible action. We required children (aged between 3 years 8 months and 7 years 11 months) to respond to actions performed by an experimenter (e.g., two hands clapping) with both compatible actions (i.e., two hands clapping) and incompatible actions (i.e., two hands waving) at different stages in the experimental procedure. As predicted by a learning account, actions thought to be performed in synchrony (i.e., clapping/waving) produced stronger automatic imitation effects when compared with actions where previous sensorimotor experience is likely to be more limited (e.g., pointing/hand closing). Furthermore, these automatic imitation effects were not found to vary with age, with both compatible and incompatible responses quickening with age. These findings suggest a role for sensorimotor experience in the development of imitative ability. PMID- 29571029 TI - CD137: A checkpoint regulator involved in atherosclerosis. AB - Inflammation is associated with atherosclerotic plaque development and precipitation of myocardial infarction and stroke, and anti-inflammatory therapy may reduce disease severity. Costimulatory molecules are key regulators of immune cell activity and inflammation, and are associated with disease development in atherosclerosis. Accumulating evidence indicates that a costimulatory molecule of the Tumor Necrosis Factor Receptor superfamily, the checkpoint regulator CD137, promotes atherosclerosis and vascular inflammation in experimental models. In light of the burgeoning consideration of CD137-targeted therapy in the clinic, it will be important to better understand costimulator immunobiology in development of cardiovascular disease. Here, we review available data on the costimulator CD137 and its potential role in atherosclerosis. PMID- 29571030 TI - Prediction of new-onset atrial fibrillation after first-ever ischemic stroke: A comparison of CHADS2, CHA2DS2-VASc and HATCH scores and the added value of stroke severity. AB - BACKGROUND AND AIMS: Early detection of atrial fibrillation after stroke is important for secondary prevention in stroke patients without known atrial fibrillation (AF). We aimed to compare the performance of CHADS2, CHA2DS2-VASc and HATCH scores in predicting AF detected after stroke (AFDAS) and to test whether adding stroke severity to the risk scores improves predictive performance. METHODS: Adult patients with first ischemic stroke event but without a prior history of AF were retrieved from a nationwide population-based database. We compared C-statistics of CHADS2, CHA2DS2-VASc and HATCH scores for predicting the occurrence of AFDAS during stroke admission (cohort I) and during follow-up after hospital discharge (cohort II). The added value of stroke severity to prediction models was evaluated using C-statistics, net reclassification improvement, and integrated discrimination improvement. RESULTS: Cohort I comprised 13,878 patients and cohort II comprised 12,567 patients. Among them, 806 (5.8%) and 657 (5.2%) were diagnosed with AF, respectively. The CHADS2 score had the lowest C-statistics (0.558 in cohort I and 0.597 in cohort II), whereas the CHA2DS2-VASc score had comparable C-statistics (0.603 and 0.644) to the HATCH score (0.612 and 0.653) in predicting AFDAS. Adding stroke severity to each of the three risk scores significantly increased the model performance. CONCLUSIONS: In stroke patients without known AF, all three risk scores predicted AFDAS during admission and follow-up, but with suboptimal discrimination. Adding stroke severity improved their predictive abilities. These risk scores, when combined with stroke severity, may help prioritize patients for continuous cardiac monitoring in daily practice. PMID- 29571031 TI - Defining the upper extremity range of motion for safe automobile driving. AB - BACKGROUND: There are no guidelines for return to driving following upper extremity injury. A greater comprehension of the role of the upper extremity in driving is required to assist clinicians in their fitness-to-drive assessments. This research aims to assist clinicians by analyzing the motion at the upper extremity in safe automobile driving. METHODS: Thirty-six participants were recruited to the Monash University Accident Research Centre's driving simulator. They were tested in a realistic driving simulation using highway scenarios and traffic hazards. An OptiTrackTM motion tracking system recorded participants' upper limb movements. FINDINGS: The following ranges of motion were recorded (left and right arm mean whole numbers): The shoulder flexed from 14 to 54 degrees , abducted to 18 degrees and adducted to 9 degrees . Shoulder rotation ranged from 6 degrees external to 32 degrees internal rotation. Elbow flexion ranged from 35 degrees to 72 degrees . Pronation reached 77 degrees and supination to 24 degrees . Wrist flexion reached 34 degrees and extension reached 23 degrees . The wrist deviated to 17 degrees radially and 38 degrees ulnar. To avoid simulated hazards, the steering wheel revolved 57.2 degrees (SD 19.2). The key movements in hazard avoidance are shoulder flexion, shoulder rotation, forearm rotation and wrist deviation. INTERPRETATION: Shoulder flexion, internal rotation and forearm rotation have been shown to be key upper extremity movements in safe driving. Clinicians can refer to the ranges of motion recorded in this investigation, or the driving task at hand in their fitness-to-drive assessments. The ability to revolve the steering wheel 100 degrees exceeds the 95th percentile of the steering wheel revolution angle required to avoid simulated traffic hazards.

AB - BACKGROUND: Orthopedic braces made by Computer-Aided Design and Manufacturing and numerical simulation were shown to improve spinal deformities correction in adolescent idiopathic scoliosis while using less material. Simulations with BraceSim (Rodin4D, Groupe Lagarrigue, Bordeaux, France) require a sagittal radiograph, not always available. The objective was to develop an innovative modeling method based on a single coronal radiograph and surface topography, and assess the effectiveness of braces designed with this approach. METHODS: With a patient coronal radiograph and a surface topography, the developed method allowed the 3D reconstruction of the spine, rib cage and pelvis using geometric models from a database and a free form deformation technique. The resulting 3D reconstruction converted into a finite element model was used to design and simulate the correction of a brace. The developed method was tested with data from ten scoliosis cases. The simulated correction was compared to analogous simulations performed with a 3D reconstruction built using two radiographs and surface topography (validated gold standard reference). FINDINGS: There was an average difference of 1.4 degrees /1.7 degrees for the thoracic/lumbar Cobb angle, and 2.6 degrees /5.5 degrees for the kyphosis/lordosis between the developed reconstruction method and the reference. The average difference of the simulated correction was 2.8 degrees /2.4 degrees for the thoracic/lumbar Cobb angles and 3.5 degrees /5.4 degrees the kyphosis/lordosis. INTERPRETATION: This study showed the feasibility to design and simulate brace corrections based on a new modeling method with a single coronal radiograph and surface topography. This innovative method could be used to improve brace designs, at a lesser radiation dose for the patient.

AB - Child maltreatment, including abuse (physical, emotional, and sexual) and neglect (physical and emotional), is positively associated with depressive symptoms in adulthood. However, most studies have been conducted within a psychopathological framework and focused on underlying dysfunctional processes (e.g., insecure attachment styles, maladaptive schemas, and negative attribution styles). Protective factors that affect the relationship between child maltreatment and adult depressive symptoms are underexplored. Guided by emotion regulation theory and the perspective of positive psychology, we examined the roles of self compassion and gratitude as protective factors in the relationship between child maltreatment and adult depressive symptoms in a sample of 358 college students. Results showed that psychological maltreatment (emotional abuse and emotional neglect) was associated with adult depressive symptoms through decreased self compassion. Neglect (emotional neglect and physical neglect) and sexual abuse were associated with adult depressive symptoms through decreased gratitude. There was no association between physical abuse and depressive symptoms through either self-compassion or gratitude. Our findings suggest that clinical practices focusing on self-compassion and gratitude might help prevent the development of adult depressive symptoms among clients with a history of maltreatment in childhood. PMID- 29571034 TI - Recommendations and requirements for reporting on applications of electric pulse delivery for electroporation of biological samples. AB - Electric field-induced membrane changes are an important approach in the life sciences. However, the developments in knowledge and translational applications face problems of reproducibility. Indeed, a quick survey of the literature reveals a lack of transparent and comprehensive reporting of essential technical information in many papers. Too many of the published scientific papers do not contain sufficient information for proper assessment of the presented results. The general rule/guidance in reporting experimental data should require details on exposure conditions such that other researchers are able to evaluate, judge and reproduce the experiments and data obtained. To enhance dissemination of information and reproducibility of protocols, it is important to agree upon nomenclature and reach a consensus on documentation of experimental methods and procedures. This paper offers recommendations and requirements for reporting on applications of electric pulse delivery for electroporation of biological samples in life science. PMID- 29571035 TI - Prevalence and age-wise distribution of Human Papillomavirus type 16/18 infections among hospital screened women of a peri-urban area in West Bengal: Impact of socio-demographic factors. AB - BACKGROUND: We undertook the current study on cervical Human Papillomavirus (HPV) prevalence along with cytology in women visiting the Gynecology Out-patient Department of a hospital for common gynecological ailments, subsequent to our earlier population-based study on HPV prevalence from India. METHODS: We analyzed data on cervical-cytology (Pap smears) and PCR-based molecular detection of HPV infection along with socio-demographic variables (N = 696). RESULTS: We identified 36.84% HPV-positive women amongst whom, HPV16 and 18 together predominated (79.37%) over other HPV types (20.63%). Contrarily, only 6.4% women revealed abnormal cytological lesions, of which, 46.51% were HPV-positive and 95% of such women harbored HPV16/18, while 5% harbored other HPV types. Individuals with normal cytology portrayed 36.09% HPV infections, of which, 77.97% were HPV16/18-positive and 22.03% harbored other HPV types. Overall HPV prevalence decreased significantly (ptrend = 0.047) with increase in age, but HPV16/18 infections were significantly over-represented compared to the other HPV types across all age-groups. Specifically, HPV16 prevalence increased (p trend < 0.01) with increase in severity of cervical lesions. HPV16 prevalence did not differ between the Hindus and Muslims but HPV18 was significantly higher among the cytologically normal Muslim women (24.14%, p = 0.02), compared to the Hindus (11.91%), specifically among those >= 30 years of age. There was a significant (p < 0.05) overrepresentation of HPV16 prevalence among women who were users of oral contraceptive-pills, irrespective of cytology. CONCLUSIONS: Our study highlights the need for HPV16/18-based screening of cervical cancers in India considering the immense socio-cultural and genetic diversity at the population level.

AB - An approach based on self organizing map (SOM) artificial neural networks is proposed herewith oriented towards interpreting nuclear and electrical well logging data. The well logging measurements of Kodana well in Southern Syria have been interpreted by applying the proposed approach. Lithological cross-section model of the basaltic environment has been derived and four different kinds of basalt have been consequently distinguished. The four basalts are hard massive basalt, hard basalt, pyroclastic basalt and the alteration basalt products- clay. The results obtained by SOM artificial neural networks are in a good agreement with the previous published results obtained by other different techniques. The SOM approach is practiced successfully in the case study of the Kodana well logging data, and can be therefore recommended as a suitable and effective approach for handling huge well logging data with higher number of variables required for lithological discrimination purposes. PMID- 29571037 TI - 64Cu, a powerful positron emitter for immunoimaging and theranostic: Production via natZnO and natZnO-NPs. AB - 64Cu is one of the most beneficial radionuclide that can be used as a theranostic agent in Positron Emission Tomography (PET) imaging. In this current work, 64Cu was produced with zinc oxide nanoparticles (natZnONPs) and zinc oxide powder (natZnO) via the 64Zn(n,p)64Cu reaction in Tehran Research Reactor (TRR) and the activity values were compared with each other. The theoretical activity of 64Cu also was calculated with MCNPX-2.6 and the cross sections of this reaction were calculated by using TALYS-1.8, EMPIRE-3.2.2 and ALICE/ASH nuclear codes and were compared with experimental values. Transmission Electronic Microscopy (TEM), Scanning Electronic Microscopy (SEM) and X-Ray Diffraction (XRD) analysis were used for samples characterizations. From these results, it's concluded that 64Cu activity value with nanoscale target was achieved more than the bulk state target and had a good adaptation with the MCNPX result. PMID- 29571038 TI - A trithiol bifunctional chelate for 72,77As: A matched pair theranostic complex with high in vivo stability. AB - INTRODUCTION: Trithiol chelates are suitable for labeling radioarsenic (72As: 2.49 MeV beta+, 26 h; 77As: 0.683 MeV beta-, 38.8 h) to form potential theranostic radiopharmaceuticals for PET imaging and therapy. To investigate the in vivo stability of trithiol chelates complexed with no carrier added (nca) radioarsenic, a bifunctional trithiol chelate was developed, and conjugated to bombesin(7-14)NH2 as a model peptide. METHODS: A trithiol-BBN(7-14)NH2 bioconjugate and its arsenic complex were synthesized and characterized. The trithiol-BBN(7-14)NH2 conjugate was radiolabeled with 77As, its in vitro stability assessed, and biodistribution studies were performed in CF-1 normal mice of free [77As]arsenate and 77As-trithiol- BBN(7-14)NH2. RESULTS: The trithiol-BBN(7-14)NH2 conjugate, its precursors and its As-trithiol-BBN(7-14)NH2 complex were fully characterized. Radiolabeling studies with nca 77As resulted in over 90% radiochemical yield of 77As-trithiol-BBN, which was stable for over 48 h. Biodistribution studies were performed with both free [77As]arsenate and Sep Pak(r) purified 77As-trithiol-BBN(7-14)NH2. Compared to the fast renal clearance of free [77As]arsenate, 77As-trithiol-BBN(7-14)NH2 demonstrated increased retention with clearance mainly through the hepatobiliary system, consistent with the lipophilicity of the 77As-trithiol-BBN(714)NH2 complex. CONCLUSION: The combined in vitro stability of 77As-trithiol-BBN(7-14)NH2 and the biodistribution results demonstrate its high in vivo stability, making the trithiol a promising platform for developing radioarsenic-based theranostic radiopharmaceuticals. PMID- 29571039 TI - Interleukin 35: Inhibitory regulator in monocyte-derived dendritic cell maturation and activation. AB - IL-35, a novel IL-12 family member, is a potent inhibitory cytokine predominantly produced by regulatory T and B lymphocytes that exerts optimal suppression in immune response. However, it remains unclear whether IL-35 plays an inhibitory role on human dendritic cells. In the present study, we focused on the possible immunosuppressive effect of IL-35 on the differentiation, maturation and function of monocyte-derived DCs (MoDCs). Addition of exogenous IL-35 was able to partially suppress MoDCs differentiation in vitro. Subsequently, LPS was used for the maturation of MoDCs and IL-35 was found to mainly restrain the maturation of MoDCs, characterized by the remarkable down-regulation of costimulatory molecules, CD83 and HLA-DR as well as a reduced production of pro-inflammatory cytokines (IL-12p70, IFN-gamma, and TNF-alpha). Furthermore, IL-35-treated MoDCs exhibited strong inhibition in the proliferation of allogeneic CD4+/CD8+ T lymphocytes. Meanwhile, IL-35-treated MoDCs also suppressed the polarization of naive CD4+ T lymphocytes towards Th1 phenotype and impaired CD8+ T cells allogeneic responses. And the foregoing suppression of MoDCs maturation and function by IL-35 might be due to the aberrant activation of STAT1/STAT3 and inhibition of p38 MAPK/NF-kappaB signaling pathway. Our results demonstrated for the first time that IL-35 played a critical role in modulating not only adaptive immune response, but also innate immune response. The inhibitory effect of IL-35 on MoDCs maturation and function may facilitate the development of promising therapeutic interventions in tumors and other diseases. PMID- 29571040 TI - Different concentration of human cord blood HMGB1 according to delivery and labour: A pilot study. AB - OBJECTIVE: Oxidative stress is involved in several maternal conditions characterized both by an increase in free radicals synthesis and a parallel decrease in the antioxidant activity. Parturition induces considerable oxidative stress and many inflammatory mediators, among which HMGB1, are involved from the beginning of pregnancy to the birth of the infant. We evaluated serum cord blood HMGB1 levels in a population of neonates to investigate correlation with mode of delivery, as well as the influence of labour. SETTING AND PATIENTS: The study subjects were 325 neonates delivered at University Hospital "G. Martino" of Messina over an 18-month period. Following cord separation, venous blood sampling was performed on umbelical cords. RESULTS: In the cord venous blood, we found HMGB1 values significantly more elevated in spontaneous vaginal group when compared to elective or emergency caesarean section group. Regarding labour, umbilical cord venous blood HMGB1 levels were significantly higher in the spontaneous and induced labour group, compared to non-labouring women. CONCLUSION: These results could highlight a possible role of HMGB1 during birth time related to mode of delivery and labour. PMID- 29571041 TI - Microalgae-mediated bioremediation and valorization of cattle wastewater previously digested in a hybrid anaerobic reactor using a photobioreactor: Comparison between batch and continuous operation. AB - Scenedesmus obliquus (ACOI 204/07) microalgae were cultivated in cattle wastewater in vertical alveolar flat panel photobioreactors, operated in batch and continuous mode, after previous digestion in a hybrid anaerobic reactor. In batch operation, removal efficiencies ranges of 65 to 70% of COD, 98 to 99% of NH4+ and 69 to 77.5% of PO4-3 after 12days were recorded. The corresponding figures for continuous flow were from 57 to 61% of COD, 94 to 96% of NH4+ and 65 to 70% of PO4-3 with mean hidraulic retention time of 12days. Higher rates of CO2 fixation (327-547mgL-1d-1) and higher biomass volumetric productivity (213-358mgL 1d-1) were obtained in batch mode. This microalgae-mediated process can be considered promising for bioremediation and valorization of effluents produced by cattle breeding yielding a protein-rich microalgal biomass that could be eventually used as cattle feed. PMID- 29571042 TI - Comparing different methods for determining forest evapotranspiration and its components at multiple temporal scales. AB - Accurately estimating forest evapotranspiration and its components is of great importance for hydrology, ecology, and meteorology. In this study, a comparison of methods for determining forest evapotranspiration and its components at annual, monthly, daily, and diurnal scales was conducted based on in situ measurements in the subhumid mountainous forest of North China. The goal of the study was to evaluate the accuracies and reliabilities of the different methods. The results indicate the following: (1) The sap flow upscaling procedure, taking into account diversities in forest types and tree species, produced component based forest evapotranspiration estimate that agreed with eddy covariance-based estimate at the temporal scales of year, month, and day, while soil water budget based forest evapotranspiration estimate was also qualitatively consistent with eddy covariance-based estimate at the daily scale; (2) At the annual scale, catchment water balance-based forest evapotranspiration estimate was significantly higher than eddy covariance-based estimate, which might probably result from non-negligible subsurface runoff caused by the widely distributed regolith and fractured bedrock under the ground; (3) At the sub-daily scale, the diurnal course of sap flow based-canopy transpiration estimate lagged significantly behind eddy covariance-based forest evapotranspiration estimate, which might physiologically be due to stem water storage and stem hydraulic conductivity. The results in this region may have much referential significance for forest evapotranspiration estimation and method evaluation in regions with similar environmental conditions. PMID- 29571043 TI - Transposon control mechanisms in telomere biology. AB - The ends of linear eukaryotic chromosomes, telomeres, are elongated by reverse transcriptase activity provided by the enzyme telomerase, or by specialized telomeric retrotransposons. Telomerase and telomeric retrotransposons represent unique examples of structurally different, but evolutionary and functionally related machineries that generate essential chromosome structures, namely telomeres. In fact, the telomere is an example of the taming of retroelements for the maintenance of essential genome function. Many features of telomere homeostasis are conserved between telomerase and retrotransposon maintained telomeres. The retrotransposon origin of telomeres suggests that mechanisms of transposon control could be adopted for telomere regulation. The discovery of the role of Drosophila telomeric piRNAs in telomere length control and the influence of LINE-1 retroelements on telomere regulation in human cells strongly support this idea and allow us to look at telomere regulation from a new angle. PMID- 29571044 TI - Duplication of host genes by transposable elements. AB - The availability of large amounts of genomic and transcriptome sequences have allowed systematic surveys about the host gene sequences that have been duplicated by transposable elements. It is now clear that all super-families of transposons are capable of duplicating genes or gene fragments, and such incidents have been detected in a wide spectrum of organisms. Emerging evidence suggests that a considerable portion of them function as coding or non-coding sequences, driving innovations at molecular and phenotypic levels. Interestingly, the duplication events not only have to occur in the reproductive tissues to become heritable, but the duplicated copies are also preferentially expressed in those tissues. As a result, reproductive tissues may serve as the 'incubator' for genes generated by transposable elements. PMID- 29571045 TI - The benefits and pitfalls of post-mortem computed tomography in forensic external examination: A retrospective study of 145 cases. AB - OBJECTIVE: Nowadays, post-mortem computed tomography (PMCT) has become an integral part of Forensic practice. The purpose of the study was to determine PMCT impact on diagnosis of the cause of death within the context of the external examination of the body, when autopsy has, at first, not been requested. MATERIAL AND METHODS: We reviewed the records of 145 cases for which unenhanced PMCT was performed in addition to the external examination of the body from January 2014 to July 2015 at the Institute of Forensic medicine in Strasbourg (France). We confronted final reports from forensic pathologist to the corresponding PMCT reports. Data were collected in a contingency table and the impact of PMCT on the final conclusions of the forensic pathologist was evaluated via a Chi2 test. RESULTS: PMCT results significantly impact the final conclusions of forensic pathologist (p<0,001). In some cases, PMCT permits etiological diagnosis by revealing a cause of death hidden from external examination (mainly natural death) or by supporting the clinical findings of the forensic pathologist. In other cases (traumatic death), PMCT enables fast and exhaustive lesion assessment. Lastly, there are situations where PMCT may be ineffective (intoxication, hanging or some natural deaths). CONCLUSION: Performing PMCT within the context of the external examination of the body when autopsy has, at first, not been requested could bring significant benefits in diagnosing the cause of death. The impact of PMCT varies depending on the circumstances of death. PMID- 29571046 TI - The contributions of Dr. Kathleen K. Sulik to fetal alcohol spectrum disorders research and prevention. AB - Dr. Kathleen Sulik (Kathy) has spent 35 years studying fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD). Beginning with her landmark 1981 Science paper describing the early gestational window when alcohol can cause the craniofacial malformations characteristic of FAS, Kathy has contributed a vast amount of research furthering our knowledge of FASD. After her seminal work that definitively demonstrated that alcohol is the causative factor in FAS, she and her lab went on to explore and define the stage-dependent effects of early gestational alcohol exposure on the face and brain in numerous different ways throughout her career. She explored and discovered numerous mechanisms of alcohol's effects on the embryo, as well as describing several genetic factors that can modify susceptibility to developmental alcohol exposure. She did not restrict her research to the face and brain; her lab described in intricate detail the effects of developmental alcohol exposure on many different organs, including the heart, ears, kidneys, and limbs. In addition to her research, and in conjunction with NIAAA and the National Organization on Fetal Alcohol Syndrome (NOFAS), Kathy developed several FASD prevention curricula that are still in use today. Finally, as part of her drive to eradicate FAS and FASD, Kathy labored tirelessly with public policy makers to change how FASD is viewed by the public, how FASD is identified in affected individuals, and how FASD is studied by researchers. While no article could fully cover Kathy's contributions to FASD research and prevention, or her other contributions to embryology and teratology, this review will attempt to illustrate some of the highlights of Kathy's remarkable career. PMID- 29571047 TI - Enhanced sensitivity to socially facilitating and anxiolytic effects of ethanol in adolescent Sprague Dawley rats following acute prenatal ethanol exposure. AB - Emerging evidence suggests that deficits in social functioning and social anxiety are associated with adolescent alcohol use. Our previous research has shown that acute exposure to a high dose of ethanol on gestational day (G) 12 produces social alterations in adolescent Sprague Dawley rats. The present study assessed whether these social alterations can affect sensitivity to acute ethanol challenge during adolescence. Pregnant females were exposed intraperitoneally (i.p.) to ethanol (2.5 g/kg followed by 1.25 g/kg in 2 h) or saline on G12, and their male and female offspring were tested on postnatal day (P) 42. Rats were challenged i.p. with one of four ethanol doses (0, 0.5, 0.75, and 1.0 g/kg), and their social behavior was assessed in a modified social interaction test. Social alterations associated with prenatal ethanol exposure and indexed via decreases of social investigation, social preference, and play fighting were evident in males and females challenged with the 0 g/kg ethanol dose. Acute ethanol increased social investigation, social preference, and play fighting in animals prenatally exposed to ethanol. In contrast, rats prenatally exposed to saline, showing no social facilitation, demonstrated significant ethanol-induced (0.75 and 1.0 g/kg) decreases in social behavior. Given that late adolescents demonstrating social alterations induced by prenatal ethanol exposure become sensitive to the socially anxiolytic as well as socially facilitating effects of acute ethanol, it is possible that the attractiveness of ethanol to these adolescents may be based on its ability to alleviate anxiety under social circumstances and facilitate interactions with peers. PMID- 29571048 TI - Associations among animal, carcass, muscle characteristics, and fresh meat color traits in Charolais cattle. AB - This study investigated the effects of animal, carcass and muscle characteristics on initial color traits of steaks from 887 Charolais cattle. First, the fixed factors of year of birth, experiment and sex had strong impacts on color traits. From the covariates, increased age lead to intense color (low h*, -1.55 units) and darker and vivid meat (high a*, b* and C*: +4.56, +3.41 and +5.61, respectively). Increases in fatness score and carcass fat weight were associated with increases in a*, b* and C* (redness; +2.90 to +4.06 for a*; yellowness; +2.60 to +3.76 for b*; and vividness, +3.87 to +5.49 for C*) and a darker colored lean (L*; -1.56 to -3.23). As pH24h increased, a* (less red) and C* (less vivid) decreased (-3.06), whereas hue angle increased (+2.69) leading to poorer color. The selection of animals for high degree of muscularity or slaughter weight resulted in lighter and darker meat, respectively. The studied covariates could be used as indicators of Charolais beef color traits. PMID- 29571050 TI - Novel angiogenesis therapeutics by redox injectable hydrogel - Regulation of local nitric oxide generation for effective cardiovascular therapy. AB - Nitric oxide (NO) possesses various functions in cardiovascular diseases; however, due to an extremely short half-life and low bioavailability, its therapeutic application is limited. In inflamed tissues, overproduced reactive oxygen species (ROS) rapidly react with the endogenous NO, reducing its bioavailability. Here, we developed a controllable NO-releasing redox injectable hydrogel (NO-RIG) formed by the electrostatic crosslinking between the polyion complex flower-type micelles composing of functional polymers to scavenge overproduced ROS and regulate the local NO expression level simultaneously. After the intracardiac injection to mice, NO-RIG converted to gel via physiological temperature-responsive character, distributed homogeneously, and retained in the myocardial tissue for more than 10 d. Treatment with NO-RIG remarkably decreased the infarction size and improved the heart function after myocardial infarction when compared to control injectable hydrogels, such as a simple NO-releasing or ROS-scavenging injectable gels. We found that NO-RIG treatment significantly enhanced the angiogenesis and new blood vessels formation in mice through the regulation of the NO sustained release and redox equilibrium. NO-RIG presents high potential in preventing and treating cardiovascular diseases. PMID- 29571051 TI - Substrate stiffness modulates the multipotency of human neural crest derived ectomesenchymal stem cells via CD44 mediated PDGFR signaling. AB - Mesenchymal stem cells (MSCs) have been isolated from various mesodermal and ectodermal tissues. While the phenotypic and functional heterogeneity of MSCs stemming from their developmental origins has been acknowledged, the genetic and environmental factors underpinning these differences are not well-understood. Here, we investigated whether substrate stiffness mediated mechanical cues can directly modulate the development of ectodermal MSCs (eMSCs) from a precursor human neural crest stem cell (NCSC) population. We showed that NCSC-derived eMSCs were transcriptionally and functionally distinct from mesodermal bone marrow MSCs. eMSCs derived on lower substrate stiffness specifically increased their expression of the MSC marker, CD44 in a Rho-ROCK signaling dependent manner, which resulted in a concomitant increase in the eMSCs' adipogenic and chondrogenic differentiation potential. This mechanically-induced effect can only be maintained for short-term upon switching back to a stiff substrate but can be sustained for longer-term when the eMSCs were exclusively maintained on soft substrates. We also discovered that CD44 expression modulated eMSC self-renewal and multipotency via the downregulation of downstream platelet-derived growth factor receptor beta (PDGFRbeta) signaling. This is the first instance demonstrating that substrate stiffness not only influences the differentiation trajectories of MSCs but also their derivation from upstream progenitors, such as NCSCs. PMID- 29571049 TI - Lanthanide-doped nanoparticles conjugated with an anti-CD33 antibody and a p53 activating peptide for acute myeloid leukemia therapy. AB - Roughly one third of all human cancers are attributable to the functional inhibition of the tumor suppressor protein p53 by its two negative regulators MDM2 and MDMX, making dual-specificity peptide antagonists of MDM2 and MDMX highly attractive drug candidates for anticancer therapy. Two pharmacological barriers, however, remain a major obstacle to the development of peptide therapeutics: susceptibility to proteolytic degradation in vivo and inability to traverse the cell membrane. Here we report the design of a fluorescent lanthanide oxyfluoride nanoparticle (LONp)-based multifunctional peptide drug delivery system for potential treatment of acute myeloid leukemia (AML) that commonly harbors wild type p53, high levels of MDM2 and/or MDMX, and an overexpressed cell surface receptor, CD33. We conjugated to LONp via metal-thiolate bonds a dodecameric peptide antagonist of both MDM2 and MDMX, termed PMI, and a CD33 targeted, humanized monoclonal antibody to allow for AML-specific intracellular delivery of a stabilized PMI. The resultant nanoparticle antiCD33-LONp-PMI, while nontoxic to normal cells, induced apoptosis of AML cell lines and primary leukemic cells isolated from AML patients by antagonizing MDM2 and/or MDMX to activate the p53 pathway. Fluorescent antiCD33-LONp-PMI also enabled real-time visualization of a series of apoptotic events in AML cells, proving a useful tool for possible disease tracking and treatment response monitoring. Our studies shed light on the development of antiCD33-LONp-PMI as a novel class of antitumor agents, which, if further validated, may help targeted molecular therapy of AML. PMID- 29571052 TI - Non-eluting, surface-bound enzymes disrupt surface attachment of bacteria by continuous biofilm polysaccharide degradation. AB - Bacterial colonization and biofilm formation on surfaces are typically mediated by the deposition of exopolysaccharides and conditioning protein layers. Pseudomonas aeruginosa is a nosocomial opportunistic pathogen that utilizes strain-specific exopolysaccharides such as Psl, Pel or alginate for both initial surface attachment and biofilm formation. To generate surfaces that resist P. aeruginosa colonization, we covalently bound a Psl-specific glycoside hydrolase (PslGh) to several, chemically-distinct surfaces using amine functionalization (APTMS) and glutaraldehyde (GDA) linking. In situ quartz crystal microbalance (QCM) experiments and fluorescence microscopy demonstrated a complete lack of Psl adsorption on the PslGh-bound surfaces. Covalently-bound PslGh was also found to significantly reduce P. aeruginosa surface attachment and biofilm formation over extended growth periods (8 days). The PslGh surfaces showed a ~99.9% (~3-log) reduction in surface associated bacteria compared to control (untreated) surfaces, or those treated with inactive enzyme. This work demonstrates a non eluting 'bioactive' surface that specifically targets a mechanism of cell adhesion, and that surface-bound glycoside hydrolase can significantly reduce surface colonization of bacteria through local, continuous enzymatic degradation of exopolysaccharide (Psl). These results have significant implications for the surface design of medical devices to keep bacteria in a planktonic state, and therefore susceptible to antibiotics and antimicrobials. PMID- 29571053 TI - Functionalized poly(pyrrole-3-carboxylic acid) nanoneedles for dual-imaging guided PDT/PTT combination therapy. AB - Herein, poly(pyrrole-3-carboxylic acid) (PPyCOOH) nanoneedles with abundant carboxyl groups were synthesized by aqueous dispersion polymerization method using pyrrole-3-carboxylic acid as conductive polymer monomer. The PPyCOOH nanoneedles not only owned good photothermal performance, but also more importantly showed enhanced tumor cell uptake efficiency (1.64 fold) compared with size and zeta-potential matched nanospheres. After loading photosensitizer aluminum phthalocyanine tetrasulfonate (AlPCS4) and modifying with poly(allylamine hydrochloride) (PAH) and poly(acrylic acid) (PAA) onto the PPyCOOH nanoneedles, novel nanoneedle complexes (AlPCS4@PPyCONH-PAH-PAA) integrating photodynamic therapy (PDT) and photothermal therapy (PTT) were successfully fabricated. The as-prepared nanoneedle complexes improved uptake efficiency of AlPCS4 both in vitro and in vivo. Moreover, the nanoneedle complexes have infrared thermal and fluorescent properties. By combined PDT/PTT under the guiding of dual modal imaging, the tumors in mice were completely eliminated and no recurrence was observed in 30 days after treatment, indicating that PPyCOOH nanoneedles have great potential as a novel drug carrier for constructing multifunctional nanoplatform used for cancer treatment. PMID- 29571054 TI - Understanding interactions between biomaterials and biological systems using proteomics. AB - The role that biomaterials play in the clinical treatment of damaged organs and tissues is changing. While biomaterials used in permanent medical devices were required to passively take over the function of a damaged tissue in the long term, current biomaterials are expected to trigger and harness the self regenerative potential of the body in situ and then to degrade, the foundation of regenerative medicine. To meet these different requirements, it is imperative to fully understand the interactions biomaterials have with biological systems, in space and in time. This knowledge will lead to a better understanding of the regenerative capabilities of biomaterials aiding their design with improved functionalities (e.g. biocompatibility, bioactivity). Proteins play a pivotal role in the interaction between biomaterials and cells or tissues. Protein adsorption on the material surface is the very first event of this interaction, which is determinant for the subsequent processes of cell growth, differentiation, and extracellular matrix formation. Against this background, the aim of the current review is to provide insight in the current knowledge of the role of proteins in cell-biomaterial and tissue-biomaterial interactions. In particular, the focus is on proteomics studies, mainly using mass spectrometry, and the knowledge they have generated on protein adsorption of biomaterials, protein production by cells cultured on materials, safety and efficacy of new materials based on nanoparticles and the analysis of extracellular matrices and extracellular matrix-derived products. In the outlook, the potential and limitations of this approach are discussed and mass spectrometry imaging is presented as a powerful technique that complements existing mass spectrometry techniques by providing spatial molecular information about the material biological system interactions. PMID- 29571055 TI - Nucleosome-inspired nanocarrier obtains encapsulation efficiency enhancement and side effects reduction in chemotherapy by using fullerenol assembled with doxorubicin. AB - Chemodrugs have been widely used to treat cancer; however, the chemotherapy usually leads to serious side effects and failure. Various nanomaterials and strategies have been explored for drug delivery to improve the efficacy of chemodrugs. One key to loading chemodrugs onto a nano-delivery system is enhancement of the encapsulation efficiency, especially for polymeric nanoparticles being loaded with hydrophilic drugs. Inspired by the ability of eukaryote to package millions of genes in the nucleus wrapping and condensing DNA around histones to form chromosomes, here we developed a karyon-like hybrid nanoparticle to achieve ultra-high encapsulation of doxorubicin (Dox) with reduced side effects. We utilized fullerenol as a "histone", packaged a great number of Dox, and used PEG-PLGA as the "karyotheca" coating the "nucleosome" (fullerenol and Dox complex) to stabilize the complex. It is noteworthy that the encapsulation efficiency of Dox in the polymeric micelles was increased from ~5% to ~79%. What's more, the biomimetic-inspired delivery system significantly reduced the chemodrug side effects by utilizing the radical scavenging ability of fullerenol. This novel drug-delivery design approach provides useful insights for improving the applicability of fullerenol in drug delivery systems for cancer therapy.

PMID- 29571057 TI - Panayiotopoulos syndrome and benign partial epilepsy with centro-temporal spikes: A comparative incidence study. AB - PURPOSE: To compare the de novo incidence of Panayiotopoulos syndrome (PS, early onset childhood occipital epilepsy) and a common epilepsy syndrome, benign epilepsy with centro-temporal spikes (BECTS), in children and young people. METHODS: The incidence of PS and BECTS was recorded over 16 months in a population of children and young people (aged <16 years) living within a specific geographic area and epilepsy network within the North West of England and North Wales and the catchment area of the tertiary paediatric epilepsy centre. Monthly data collection proformas were circulated to the paediatricians and paediatric neurologists responsible for the evaluation of epilepsy in children within this area. This also included monthly reminders of the electro-clinical criteria for these syndromes. EEGs were undertaken in the neurophysiology department of the tertiary paediatric epilepsy centre. The departmental EEG database on all <16 year olds that underwent an EEG during the study period was examined to identify additional patients that may not have been reported via a proforma-reporting system. RESULTS: The incidence of PS and BECTS was found to be 0.8 and 6.1 per 100,000 <16 year olds, respectively. The ages at seizure onset and diagnosis were similar for BECTS and PS. CONCLUSION: This study is the first to determine a comparative incidence of PS and BECTS. The findings suggest BECTS is eight times more common than PS and that the incidence of PS is lower than previously suggested.

AB - The surface defense molecules of aquatic invertebrates against infectious microorganisms have remained largely unexplored. In the present study, hemagglutinins were isolated from an extract of body surface layer of Japanese sea cucumber, Apostichopus japonicus, by affinity chromatography with fixed rabbit erythrocyte membranes. The N-terminal sequence of a 15-kDa agglutinin was almost identical with that of SJL-1, a C-type lectin formerly identified in this species. Because cDNA sequence and tissue distribution of SJL-1 have not been reported, we performed cDNA sequencing, gene expression analysis, and western blotting and immunohistochemical evaluation with anti-recombinant SJL-1 (rSJL-1) antibodies. The hemagglutinin gene was transcribed mainly in the integument, tentacles, and respiratory tree. Western blotting revealed that SJL-I is present in a body surface rinse, indicating that SJL-1 is secreted onto the body surface. SJL-1-positive cells scattered beneath the outermost layer of the integument were detected by immunohistochemistry. Furthermore, rSJL-1 agglutinated Gram-positive and Gram-negative bacteria, and yeast. These results indicate that SJL-1 acts as a surface defense molecule in A. japonicus. PMID- 29571059 TI - Relative antibacterial functions of complement and NETs: NETs trap and complement effectively kills bacteria. AB - Neutrophil extracellular traps (NETs) are web-like DNA structures released by activated neutrophils. These structures are decorated with antimicrobial proteins, and considered to trap and kill bacteria extracellularly. However, the exact functions of NETs remain elusive, and contradictory observations have been made with NETs functioning as an antimicrobial or a pathogentrapping mechanism. There is a disconnect in the interpretation of the involvement of other major immune mechanisms, such as the complement system, as effectors of the function of NETs. We have recently shown that NETs activate complement. In this study, we aimed to elucidate the relative antimicrobial roles of NETs in the absence and presence of complement. Using primary human neutrophils, human serum (normal, heat inactivated, and C5-depleted), P. aeruginosa (at multiplicity of infection, MOI, of 1 or 10), S. aureus (MOI of 1), colony-counting assays and confocal microscopy, we demonstrate that most bacteria trapped by NETs remain viable, indicating that NETs have limited bactericidal properties. By contrast, complement effectively killed bacteria, but NETs decreased the bactericidal ability of complement and degrading NETs by DNases restored complement-mediated killing. Experiments with conditions allowing for specific pathway activation showed that the complement classical and lectin, but not the alternative, pathway lead to bacterial killing. NETs under static conditions showed limited killing of bacteria while NETs under dynamic conditions showed enhanced bacteria trapping and reduced killing. Furthermore, NETs incubated with normal human serum depleted complement and reduced the hemolytic capacity of the serum. This report, for the first time, clarifies the relative bactericidal contributions of NETs and complement. We propose that - while NETs can ensnare bacteria such as P. aeruginosa - complement is necessary for efficient bacterial killing.

AB - INTRODUCTION: Foreign body ingestion is a common clinical presentation with less than 1% of the cases requiring surgical intervention. In this report, we present a rare case of razor blades lodged in the appendix as a result of intentional ingestion. PRESENTATION OF CASE: A 25 year old male prisoner presented to our hospital with persistent right iliac fossa pain after razor blade ingestion. After 5 days of conservative management, there was no sign of transition on serial X-Rays. Laparoscopy with intraoperative image intensification confirmed the presence of the razor blades in the appendix and appendicectomy was subsequently performed without complications. DISCUSSION: Most ingested objected with diameter less than 2.5 cm and length less than 6 cm can pass through the gastrointestinal tract spontaneously in less than one week. The entry of foreign objects into the appendix is thought to be due to relative low motility of the caecum, the dependent position of the appendix and the size of the appendiceal orifice. Radiographic localisation to the appendiceal lumen was complicated by metallic artefact, but was consistent with failure to transit. Appendicectomy was felt to be the safest mode of retrieval. CONCLUSION: Ingested foreign body lodged in the appendix is a rare event. Once the exact location is confirmed, a simple laparoscopic appendicectomy can be performed to facilitate the removal. PMID- 29571060 TI - Hypertrophic spinal pachymeningitis associated with human T-cell lymphotrophic virus-1 infection and Sjogren's syndrome: A case report and brief literature review. AB - INTRODUCTION: Reports of hypertrophic spinal pachymeningitis associated with human T-cell lymphotrophic virus-1 (HTLV-1) infection and Sjogren's syndrome in the English literature are still very rare. PRESENTATION OF CASE: We hereby present a case of a 78-year-old female with a history of lower extremity weakness after a fall, which fully resolved after conservative treatment. However, the symptoms recurred 4 years later, and the patient became unable to walk. The patient had no superficial or deep sensation below the level of T9, and she also had urinary retention. Magnetic resonance imaging showed that hypertrophic dura mater was compressing the spinal cord from T2 to T10. Blood testing revealed increased anti-HTLV-1 antibody, rheumatoid factor, elevation of anti-SS-A antibody and antinuclear antibody. The cerebrospinal fluid contained markedly elevated levels of total protein and cell numbers. Biopsy of the labial gland of the lip revealed chronic sialadenitis. DISCUSSION: In collaboration with a neurologist, we diagnosed this patient with hypertrophic spinal pachymeningitis associated with HTLV-1 infection and Sjogren's syndrome. We performed laminectomy at the affected spinal levels, resected the thickened dura, and maintained the patient on steroid therapy. The patient attained a marked recovery; she could walk with a cane and her urinary retention was improved. CONCLUSION: For the management of HSP associated with HTLV-1 and SS, we recommend surgical decompression with subsequent prolonged steroid therapy and prolonged close monitoring to achieve a good long-term outcome. PMID- 29571062 TI - The potentiality of laparoscopic partial liver excisional biopsy using analysis of the liver surface based on preoperative 3D simulation imaging: A case report. AB - INTRODUCTION: The imaging diagnostics of liver tumor are difficult. There are no effective biopsy examinations for liver tumors that cannot be detected even by ultrasonography (US) and computed tomography (CT). We report a remarkably useful biopsy method for such tumors. PRESENTATION OF CASE: A 67-year-old man with hepatitis C underwent gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid enhanced magnetic resonance imaging, and the images revealed multiple delayed enhanced masses that showed high signal intensity in the hepatobiliary phase. The possibility of malignancy could not be ruled out due to the trend towards increased size of the masses. Percutaneous liver biopsy was considered impossible because CT and US could not detect the masses. Laparoscopic liver biopsy with preoperative simulation using 3D imaging was performed. The 3D imaging provided accurate information of liver surface irregularities with cirrhosis change. The tumor location was confirmed, and adequate tumor excisional biopsy was performed. Histological assessment revealed the tumor to be a focal nodular hyperplasia-like nodule. DISCUSSION AND CONCLUSIONS: Laparoscopic liver biopsy has been widely used because of its safety and accuracy. It enables accurate resection of tumors that are undetectable with CT and US by employing preoperative 3D imaging while maintaining the less-invasiveness. PMID- 29571063 TI - Advantage of laparoscopic resection for pelvic Schwannoma: Case report and review of the literature. AB - INTRODUCTION: Single pelvic schwannomas are rare tumor arising from the retrorectal, lateral or obturatory space. Laparoscopic approach to schwannoma located in lateral pelvic space has been previously described only in one case report. We present a case of a successful laparoscopic resection of pelvic schwannoma emphasizing the advantages of such a minimal invasive approach. PRESENTATION OF CASE: A 54-years-old, obese, male patient was admitted to our hospital referring dysuria and strangury. Abdominal CT scan showed a lateral pelvic well-circumscribed mass with smooth regular margins. A CT-guided fine needle biopsy resulted non-diagnostic. An elective laparoscopic resection was performed. The patient had a short, uneventful post-operative course. Pathological examination revealed a benign schwannoma. DISCUSSION: Using PubMed database, we reviewed the English language international literature using the MeSH terms "laparoscopic," "minimally invasive" and "schwannoma". We identified quite 20 previous cases of pelvic schwannomas removed by laparoscopy or robotic surgery. We found out that a preoperative diagnosis of these rare neoplasms is difficult to be obtained; in most cases, laparoscopic approach was successfully performed. CONCLUSION: Despite it could not be proven yet, due to the rarity of this tumor, we agree with literature that laparoscopic removal of pelvic benign tumor may offer several advantages. The direct high-definition vision deeply into this narrow anatomical space, especially in obese patients, provides a detailed view that makes easier to isolate and spear the anatomical structures surrounding the tumor. Furthermore, the pneumoperitoneum may create the right plane of dissection, minimizing the risk of tumor rupture and bleeding. PMID- 29571064 TI - Spontaneous migration of thrombosed synthetic vascular graft to the duodenum after living-donor liver transplantation: A case-report. AB - INTRODUCTION: Spontaneous migration of synthetic grafts had been described after abdominal vascular procedures into the duodenum and small bowel. In the setting of liver transplantation, synthetic grafts are commonly used for overcoming shortened or poor-quality vasculatures. We describe a case of spontaneous migration of thrombosed synthetic vascular graft after living-donor liver transplantation (LDLT). PRESENTATION: A 59 years male patient with end stage liver disease underwent LDLT utilizing a right hemi-liver graft. Drainage of segment V vein was done to inferior vena cava using a vascular graft. Graft patency was confirmed by regular follow up doppler ultrasound. Graft thrombosis was detected on the 4th postoperative month. The patient developed anastomotic biliary stricture 3 months after LDLT, which required repeated endoscopic retrograde cholangio-pancreatography (ERCP). During an ERCP set two and half years after LDLT, the thrombosed graft was seen eroding into the first part of the duodenum. The patient was generally stable and the decision was to follow up the condition. Follow up computed tomography showed disappearance of the graft from the abdomen, and endoscopy revealed a small ulcer at the site of the migrated graft. DISCUSSION: Reports regarding spontaneous migration of synthetic grafts in this setting of LDLT are extremely rare. We report a rare case of spontaneous migration of thrombosed synthetic vascular graft into the duodenum after LDLT. CONCLUSION: We report a rare case of spontaneous migration of thrombosed synthetic vascular graft into the duodenum after LDLT. PMID- 29571065 TI - A rare case report of Morgagni Hernia with Organo-Axial Gastric Volvulus and concomitant Para-esophageal hernia, repaired laparoscopically in a Septuagenarian. AB - INTRODUCTION: Simultaneous occurrence of Morgagni and the Para-esophageal hernia is a rare clinical condition with eight case reports in the English-language literature and only four managed laparoscopically. We describe a case of a Septuagenarian patient with Morgagni and concomitant Para-esophageal hernia treated laparoscopically. PRESENTATION OF A CASE: A 71-year-old male patient, presented with a one-month history of regurgitation of acid, retrosternal burning and vomiting after eating. Computed tomography (CT) imaging demonstrated a large anterior diaphragmatic hernia, with herniation of bowel loops and anterosuperior displacement of the gastric antrum along with a grade III Para-esophageal hernia. The patient underwent simultaneous laparoscopic repair of Morgagni and Para esophageal hernia with mesh reinforcement with Nissen's total anti-reflux fundoplication. The patient's postoperative recovery was uneventful. DISCUSSION: A Morgagni Hernia is a rare congenital condition consisting of a Subcosto-sternal defect in the diaphragm. A Para-esophageal hernia is a rare variant of a hiatus hernia. Morgagni and Para-esophageal hernia may present with gastric volvulus or incarceration, requiring emergency treatment. Minimally invasive surgery is the preferred treatment, particularly for elderly patients and patients with comorbidities. The laparoscopic operation can provide excellent exposure and repair the hernia defect easily with minimal invasiveness and fewer complications. CONCLUSION: This case report highlights the co-existence of Morgagni and Para-esophageal hernias and validates the feasibility of laparoscopic repair of both hernias simultaneously. PMID- 29571066 TI - In vitro and in vivo evaluation of the bifunctional chelator NODIA-Me in combination with a prostate-specific membrane antigen targeting vector. AB - INTRODUCTION: We recently developed a chelating platform based on the macrocycle 1,4,7-triazacyclononane with up to three five-membered azaheterocyclic arms for complexation of the PET nuclides gallium-68 and copper-64. The main objective of this study was to evaluate the stability and pharmacokinetics of 68Ga- and 64Cu complexes of the bifunctional chelator NODIA-Me 1 covalently bound to a PSMA targeting vector in vivo. METHODS: NODIA-Me 1 was conjugated to the PSMA targeting Glu-NH-CO-NH-Lys moiety to give the bioconjugate NODIA-Me-NaI-Ahx-PSMA 4. The stability of [68Ga]4 and [64Cu]4 was assessed in vitro by serum stability studies. The PSMA binding affinity was determined in competitive cell experiments in LNCaP cells using 68Ga-PSMA-HBED-CC as radioligand. The stability and pharmacokinetics of [68Ga]4 and [64Cu]4 was evaluated by PET imaging and ex vivo biodistribution studies in mice bearing subcutaneous LNCaP tumors. RESULTS: In human serum, [68Ga]4 and [64Cu]4 remained intact to 85% (3 h) and 92% (24 h), respectively. Nature of the metal chelate influenced PSMA binding affinity with IC50 of 233 +/- 10 nM for uncomplexed 4, 681 +/- 7 nM for Cu-4 and 176 +/- 10 nM for Ga-4. In animal studies, [68Ga]4 and [64Cu]4 revealed low uptake (<=1% IA g 1) in the majority of organs. Kidney uptake at 1 h p.i. was 6.28 +/- 0.92% IA g-1 and 4.96 +/- 0.79% IA g-1 and specific tumor uptake was 1.33 +/- 0.46% IA g-1 and 2.15 +/- 0.38% IA g-1 for [68Ga]4 and [64Cu]4, respectively. CONCLUSION: The bifunctional chelator NODIA-Me 1 was successfully conjugated to a PSMA targeting moiety. In small-animal PET imaging and ex vivo biodistribution studies, 68Ga- and 64Cu-labelled conjugates specifically delineated PSMA-positive LNCaP tumors and exhibited rapid renal clearance from non-target tissues with no significant demetallation/transchelation in vivo. The results support further development of this novel chelating platform for production of 68Ga- and 64Cu-labelled radiopharmaceuticals. PMID- 29571067 TI - Evaluation of 177Lu[Lu]-CHX-A"-DTPA-6A10 Fab as a radioimmunotherapy agent targeting carbonic anhydrase XII. AB - INTRODUCTION: Due to their infiltrative growth behavior, gliomas have, even after surgical resection, a high recurrence tendency. The approach of intracavitary radioimmunotherapy (RIT) is aimed at inhibiting tumor re-growth by directly administering drugs into the resection cavity (RC). Direct application of the radioconjugate into the RC has the advantage of bypassing the blood-brain barrier, which allows the administration of higher radiation doses than systemic application. Carbonic anhydrase XII (CA XII) is highly expressed on glioma cells while being absent from normal brain and thus an attractive target molecule for RIT. We evaluated a CA XII-specific 6A10 Fab (fragment antigen binding) labelled with 177Lu as an agent for RIT. METHODS: 6A10 Fab fragment was modified and radiolabelled with 177Lu and characterized by MALDI-TOF, flow cytometry and radio TLC. In vitro stability was determined under physiological conditions. Biodistribution studies, autoradiography tumor examinations and planar scintigraphy imaging were performed on SCID-mice bearing human glioma xenografts. RESULTS: The in vitro CA XII binding capacity of the modified Fab was confirmed. Radiochemical purity was determined to be >90% after 72 h of incubation under physiological conditions. Autoradiography experiments proved the specific binding of the Fab to CA XII on tumor cells. Biodistribution studies revealed a tumor uptake of 3.0%ID/g after 6 h and no detectable brain uptake. The tumor-to contralateral ratio of 10/1 was confirmed by quantitative planar scintigraphy. CONCLUSION: The radiochemical stability in combination with a successful in vivo tumor uptake shows the potential suitability for future RIT applications with the 6A10 Fab.

AB - : This paper presents the irradiation and processing of high-current 100Mo targets at the University of Alberta (UofA) in a GMP compliant setting. For purpose of comparison with a second production facility, additional studies at Centre Hospitalier Universitaire de Sherbrooke (CHUS) are also described. INTRODUCTION: More than 70% of today's diagnostic radiopharmaceuticals are based on 99mTc, however the conventional supply chain for obtaining 99mTc is fragile. The aim of this work was to demonstrate reliable high yield production and processing of 99mTc with medium-energy, high-current, cyclotrons. METHODS: We used two cyclotrons (TR-24, Advanced Cyclotron Systems, Inc) for irradiations with 22 MeV or 24 MeV incident energy and 400 MUA current up to a maximum of 6 h. The irradiated 100Mo was dissolved using peroxide, basified using ammonium carbonate, and purified using a PEG-based solid phase extraction technique. RESULTS: High-yield productions with 22 MeV (400 MUA, 6 h) yielded an average isolated [99mTc]TcO4- yield of 878 GBq +/- 99 GBq (23.7 Ci +/- 2.7 Ci) decay corrected to EOB, n = 8 (isolated saturation yield: 4.36 +/- 0.49 GBq/MUA). Irradiations with 24 MeV (400 MUA, 6 h) resulted in an average isolated [99mTc]TcO4- yield of 993 GBq +/- 100 GBq (26.8 Ci +/- 2.7 Ci) decay corrected to EOB, n = 7 (isolated saturation yield: 4.97 +/- 0.50 GBq/MUA). These yields corresponds to 600-700 GBq (16-19 Ci) of [99mTc]TcO4- at release (i.e. 3 hour post-EOB). For all tested batches, the QC results were within the recently published specifications in the European Pharmacopoeia. CONCLUSION: Reliable near TBq production yields for 99mTc can be obtained using medium-energy cyclotrons. ADVANCES IN KNOWLEDGE AND IMPLICATIONS FOR PATIENT CARE: This work presents evidence that medium-energy high-current cyclotrons can provide high yields of [99mTc]TcO4- with radionuclidic impurities levels within the specifications of the existing European Pharmacopoeia monograph, indicating that this technology can have a share in the future 99mTc supply market. PMID- 29571069 TI - Tissue and cellular mechanics of seeds. AB - Distinct plant seed/fruit structures evolved to support reproduction and dispersal in distinct environments. Appropriate biomechanical properties and interactions of the various seed compartments are indispensable to plant survival. Most seeds are dispersed in a dry state generated during seed development/maturation for which novel aspects of endosperm-embryo interaction were discovered. The various layers covering the embryo of a mature seed define the patterns of water uptake during germination. Their biomechanical weakening together with embryo cell expansion is mediated by cell wall remodelling to facilitate radicle protrusion. Recent work with different species has revealed mechanisms underpinning specific embryo growth zones. Abiotic and biotic factors were shown to release different types of seed and fruit coat-mediated constraints to water uptake and germination. PMID- 29571070 TI - Effect of pterin impurities on the fluorescence and photochemistry of commercial folic acid. AB - Folic acid, or pteroyl-l-glutamic acid (PteGlu) is a conjugated pterin derivative that is used in dietary supplementation as a source of folates, a group of compounds essential for a variety of physiological functions in humans. Photochemistry of PteGlu is important because folates are not synthesized by mammals, undergo photodegradation and their deficiency is related to many diseases. We have demonstrated that usual commercial PteGlu is unpurified with the unconjugated oxidized pterins 6-formylpterin (Fop) and 6-carboxypterin (Cap). These compounds are in such low amounts that a normal chromatographic control would not detect any pterinic contamination. However, the fluorescence of PteGlu solutions is due to the emission of Fop and Cap and the contribution of the PteGlu emission, much lower, is negligible. This is because the fluorescence quantum yield (PhiF) of PteGlu is extremely weak compared to the PhiF of Fop and Cap. Likewise, the PteGlu photodegradation upon UV-A radiation is an oxidation photosensitized by oxidized unconjugated pterins present in the solution, and not a process initiated by the direct absorption of photons by PteGlu. In brief, the fluorescence and photochemical properties of PteGlu solutions, prepared using commercially available solids, are due to their unconjugated pterins impurities and not to PteGlu itself. This fact calls into question many reported studies on fluorescence and photooxidation of this compound. PMID- 29571071 TI - Differences between attached and suspended microalgal cells in ssPBR from the perspective of physiological properties. AB - Attached microalgae cultivation for the algae-based products is considered as a promising approach to simplify biomass recovery processes and reduce the cost. However, as an incipient research field, biomass accumulation is the mainly index for attached microalgal growth evaluation. To break through such limitations, physiological properties of attached microalgae (e.g. the oxygen evolving activity and the main organic composition of cells), which are important for microalgal growth evaluation but are still unclear in most studies, were studied using an attached microalgae culture system, i.e. suspended-solid phase photobioreactor (ssPBR) in this paper. As light, nutrients and other environmental conditions of attached microalgae were different from the suspended microalgae, physiological properties of attached microalgae also varied from the suspended ones. Besides the relatively lower biomass accumulation rate, attached microalgae also had a lower oxygen evolving activity (65% on average) comparing to suspended microalgae. The composition of microalgae changed towards accumulating more protein when suspended microalgae turned to attached status. The relative protein content of attached microalgae (50.1% +/- 10.1%) was approximately 30% higher than the suspended algae (36.0% +/- 16.1%) on average. The discovery of physiological properties of attached microalgae in this paper could help the production of high-protein microalgae-related products and explain some phenomenon during the production of microalgae-related products. PMID- 29571072 TI - European Psychiatric Association (EPA) guidance on forensic psychiatry: Evidence based assessment and treatment of mentally disordered offenders. AB - Forensic psychiatry in Europe is a specialty primarily concerned with individuals who have either offended or present a risk of doing so, and who also suffer from a psychiatric condition. These mentally disordered offenders (MDOs) are often cared for in secure psychiatric environments or prisons. In this guidance paper we first present an overview of the field of forensic psychiatry from a European perspective. We then present a review of the literature summarising the evidence on the assessment and treatment of MDOs under the following headings: The forensic psychiatrist as expert witness, risk, treatment settings for mentally disordered offenders, and what works for MDOs. We undertook a rapid review of the literature with search terms related to: forensic psychiatry, review articles, randomised controlled trials and best practice. We searched the Medline, Embase, PsycINFO, and Cochrane library databases from 2000 onwards for adult groups only. We scrutinised publications for additional relevant literature, and searched the websites of relevant professional organisations for policies, statements or guidance of interest. We present the findings of the scientific literature as well as recommendations for best practice drawing additionally from the guidance documents identified. We found that the evidence base for forensic-psychiatric practice is weak though there is some evidence to suggest that psychiatric care produces better outcomes than criminal justice detention only. Practitioners need to follow general psychiatric guidance as well as that for offenders, adapted for the complex needs of this patient group, paying particular attention to long-term detention and ethical issues. PMID- 29571073 TI - Concurrent Treatment with Anti-DLL4 Enhances Antitumor and Proapoptotic Efficacy of a gamma-Secretase Inhibitor in Gastric Cancer. AB - The Notch signaling pathway has been identified as a therapeutic target for cancers. gamma-Secretase inhibitors (GSIs) have been progressively recognized as potential anticancer drugs. The present study aimed to investigate the effects of anti-delta like legend 4 (anti-DLL4) treatment on the anticancer efficacy of GSIs in gastric cancer. SGC-7901-GFP human gastric cancer cells were tested for DLL4 expression by rosette formation test and immunofluorescence, and then were treated with anti-DLL4 antibody N-[N-(3,5-difluorophenacetyl)-L-ananyl]-S phenylglycine t-butyl ester (DAPT, a type of GSI), or a combination of anti-DLL4 antibody and DAPT. The effects of in vitro treatments on cell apoptosis, cell cycle, and cell invasion were analyzed. For in vivo study, an orthotopic mouse model of gastric cancer was established with green fluorescence expressing SGC 7901. Ultrasound targeted microbubble destruction was used to treat tumor-bearing mice with anti-DLL4 antibody conjugated microbubbles, DAPT, and a combination of the two. Real-time fluorescence imaging was performed to assess tumor cell inhibition in each group. Following in vivo treatments, apoptosis of tumor cells and the expression of apoptosis-related genes BAX, Bcl-2, and P53 were detected by TUNEL and immunohistochemical staining. In vivo combined treatment of anti DLL4 and DAPT led to a higher rate of cell apoptosis and greater inhibition of cell invasion than that observed with DAPT treatment alone. DAPT and anti-DLL4 combination therapy resulted in decreased cell distribution at G1 phase and increased cell distribution at S phase, compared to the untreated control group (P < .01). In vivo combined therapy with anti-DLL4 and DAPT significantly increased tumor growth inhibition and tumor cell apoptosis when compared to DAPT therapy alone (P < .05). In addition, combined treatment significantly increased expression of BAX and P53 and reduced Bcl-2 expression (P < .05). Conversely, treatment with DAPT alone only increased expression of BAX and P53 (P < .05), suggesting that the reduction of Bcl-2 expression may play an important role in the synergetic antitumor and proapoptosis effects of the combined treatment. Concurrent treatment with anti-DLL4 enhances the antitumor and proapoptotic efficacy of the gamma-secretase inhibitor in gastric cancer both in vitro and in vivo. PMID- 29571074 TI - Gene Fusion in Malignant Glioma: An Emerging Target for Next-Generation Personalized Treatment. AB - Malignant gliomas are heterogeneous diseases in genetic basis. The development of sequencing techniques has identified many gene rearrangements encoding novel oncogenic fusions in malignant glioma to date. Understanding the gene fusions and how they regulate cellular processes in different subtypes of glioma will shed light on genomic diagnostic approaches for personalized treatment. By now, studies of gene fusions in glioma remain limited, and no medication has been approved for treating the malignancy harboring gene fusions. This review will discuss the current characterization of gene fusions occurring in both adult and pediatric malignant gliomas, their roles in oncogenesis, and the potential clinical implication as therapeutic targets. PMID- 29571075 TI - Elevated body-mass index is associated with reduced white matter integrity in two large independent cohorts. AB - Obesity has been associated with a variety of neurobiological alterations. Recent neuroimaging research has pointed to the relevance of brain structural and functional alterations in the development of obesity. However, while the role of gray matter atrophy in obesity has been evidenced in several well powered studies, large scale evidence for altered white matter integrity in obese subjects is still absent. With this study, we therefore aimed to investigate potential associations between white matter abnormalities and body mass index (BMI) in two large independent samples of healthy adults. Associations between BMI values and whole brain fractional anisotropy (FA) were investigated in two independent cohorts: A sample of n = 369 healthy subjects from the Munster Neuroimaging Cohort (MNC), as well as a public available sample of n = 1064 healthy subjects of the Humane Connectome Project (HCP) were included in the present study. Tract based spatial statistics (TBSS) analyses of BMI on whole brain FA were conducted including age and sex as nuisance covariates using the FMRIB library (FSL Version 5.0). Threshold-free cluster enhancement was applied to control for multiple comparisons. In both samples higher BMI was significantly associated with strong and widespread FA reductions. These effects were most pronounced in the corpus callosum, bilateral posterior thalamic radiation, bilateral internal capsule and external capsule, bilateral inferior longitudinal fasciculus and inferior fronto-occipital fasciculus. The association was found to be independent of age, sex and other cardiovascular risk factors. No significant positive associations between BMI and FA occurred. With this highly powered study, we provide robust evidence for globally reduced white matter integrity associated with elevated BMI including replication in an independent sample. The present work thus points out the relevance of white matter alterations as a neurobiological correlate of obesity. PMID- 29571077 TI - Neonates with congenital Cytomegalovirus and hearing loss identified via the universal newborn hearing screening program. AB - BACKGROUND: Congenital cytomegalovirus (CMV) is the most common non-genetic cause of sensorineural hearing loss. Currently, there are no universal CMV screening programs for newborns or routine CMV testing of neonates with hearing loss in Australia, or elsewhere. OBJECTIVES: This study was undertaken to determine the prevalence of congenital CMV infection in infants with hearing loss identified using routine resources via the Australian universal neonatal hearing screening (UNHS) program. STUDY DESIGN: Infants who failed UNHS, referred for audiological testing and found to have permanent hearing loss were screened for CMV via PCR of urine and saliva. Congenital CMV was diagnosed if CMV was detected in infants <=30 days of age, or using retrospective testing on stored new born screening cards, retrospective testing, or using clinical criteria if >30 days of age. The cohort was analyzed for time of testing and prevalence of congenital CMV determined. RESULTS: The Audiology Department reviewed 1669 infants who failed UNHS between 2009 and 2016. Thirty percent (502/1669) had permanent hearing loss confirmed, of whom 336/502 were offered CMV testing. A definite (n = 11) or probable (n = 8) diagnosis of congenital CMV occurred in 19/323 (5.9%), of whom definite diagnoses were made in 4/19 on tests positive prior to 21 days of life, in 5/19 who were positive on neonatal blood screening card (NBSC) testing, in 2/19 who were positive on placental testing. In 8/19 probable diagnoses were made based on positive testing between ages 23-42 days and a consistent clinical syndrome in the absence of another cause for hearing loss after genetic and other testing. CMV testing mirrored the timing of audiological testing, with ~40% completing audiology and CMV testing by 21 days, and 64% by 30 days. CONCLUSION: This program, utilizing existing clinical services identified probable congenital CMV in ~6% of a large cohort failing UNHS with permanent hearing loss, of whom more than half were definite diagnoses. No additional assets were required to those already existing in this tertiary referral pediatric centre, whilst providing useful and timely data for clinical and audiological management.

AB - Interpersonal sensitivity is a personality trait linked with anxious attachment conceptualized in attachment theory. This personality trait is comprised of four components, i.e., interpersonal awareness, separation anxiety, timidity and fragile inner-self, which are measured by the corresponding subscales of the Interpersonal Sensitivity Measure (IPSM). Meanwhile, one study showed that six items of the IPSM tentatively used as negative self-schemas predicted the onset of depression. To clarify if interpersonal sensitivity reflects cognitive vulnerability, we examined the relation of this personality trait with negative core beliefs about the self. The study population consisted of 335 Japanese volunteers. Interpersonal sensitivity was measured by the IPSM, and negative core beliefs about the self were assessed by the negative-self subscale of the Brief Core Schema Scales (BCSS). Multiple regression analysis showed that scores of the four subscales of the IPSM were strongly correlated with those of the negative self subscale of the BCSS (P < 0.001). Similarly, sequential equation modeling demonstrated that the four components of interpersonal sensitivity were strongly predicted by core beliefs of negative-self (P < 0.001). The present study shows that interpersonal sensitivity is closely related to negative core beliefs about the self, suggesting that this personality trait can be regarded as a cognitive vulnerability to depression.

AB - BACKGROUND: There is a recent and growing research literature on alcohol use and related harms among transgender and other gender minority populations; however, current definitions and measures of hazardous drinking do not consider the complexity of physiological sex characteristics and socially constructed gender, raising doubts regarding their validity, applicability, and use with these populations. To address this, we reviewed current research on alcohol-related outcomes in transgender populations and critically summarized key issues for consideration in future research. METHODS: We conducted a systematic review of transgender alcohol research in English language, peer-reviewed journals, published 1990-2017, and extracted key details (e.g., sample composition, alcohol measures, results). RESULTS: Forty-four studies met all inclusion criteria for the review, the majority of which were conducted in the United States. The prevalence of hazardous drinking was high; however, estimates varied widely across studies. We noted frequent methodological weaknesses, including few attempts to differentiate sex and gender, poor attention to appropriate definitions of hazardous drinking, and reliance on cross-sectional study designs and non-probability sampling methods. CONCLUSION: Given findings that suggest high need for ongoing public health attention, we offer recommendations to improve future alcohol studies with transgender and other gender minority populations, such as being explicit as to whether and how sex and/or gender are operationalized and relevant for the research question, expanding the repertoire of alcohol measures to include those not contingent on sex or gender, testing the psychometric performance of established screening instruments with transgender populations, and shifting from descriptive to analytic study designs. PMID- 29571079 TI - Affective startle modulation in young people with first-presentation borderline personality disorder. AB - This study investigated psychophysiological and subjective emotional responses to an affective startle modulation paradigm in first-presentation borderline personality disorder (BPD). Twenty BPD and 20 healthy control participants, aged 15-24 years, viewed a set of standardized pictures with pleasant, neutral, or unpleasant valence, and were instructed to either "maintain" or "suppress" their emotional response to the stimuli. Despite showing markedly higher levels of baseline distress on self-report questionnaires, BPD participants had significantly lower skin conductance responses and showed an absence of the fear potentiated startle response during early picture processing. Both groups showed similar startle responses later in picture processing, and when instructed to "maintain" or "suppress" their emotions. BPD participants were hypo-responsive to aversive stimuli during early processing, and did not react with more intense emotional responses to affective stimuli or show a diminished ability to regulate their responses. These results might be consistent with the finding that hypersensitivity of emotional response in BPD is specific to stimuli with themes of particular relevance to this disorder, such as rejection and abandonment. PMID- 29571080 TI - Increased serum IL-36alpha and IL-36gamma levels in patients with systemic lupus erythematosus: Association with disease activity and arthritis. AB - IL-36 cytokines (IL-36Ra, IL-36alpha, IL-36beta and IL-36gamma) belong to the IL 1 family and have been linked to several autoimmune diseases. However, little is known about the relationships between systemic lupus erythematosus (SLE) and IL 36 cytokines. In this study, serum IL-36 cytokine levels were determined by enzyme-linked immunosorbent assay (ELISA), and their associations with SLE related parameters were analyzed in 72 SLE patients and 63 healthy controls. Additionally, IL-36 cytokine mRNA levels were assessed in 30 of 72 SLE patients and 20 of 63 healthy controls using real-time quantitative reverse transcription polymerase chain reaction (RT-PCR). Compared to healthy controls, SLE patients had significantly decreased serum IL-36Ra levels (P = 0.001) and markedly increased serum IL-36alpha and IL-36gamma levels (P = 0.004 and P = 0.001, respectively). Serum IL-36alpha and IL-36gamma levels were significantly higher in active SLE patients [SLE Disease Activity Index (SLEDAI) score >= 5] than in inactive patients (SLEDAI score <= 4) (P = 0.020 and P = 0.017, respectively). Serum IL-36alpha and IL-36gamma levels were strongly correlated with SLEDAI score (r = 0.308, P = 0.008 and r = 0.400, P = 0.001, respectively) and complement C3 levels (r = -0.276, P = 0.019 and r = -0.314, P = 0.007, respectively). Moreover, SLE patients with arthritis had significantly higher serum IL-36alpha and IL 36gamma levels than those without arthritis (P = 0.001 and P < 0.001, respectively). Our study indicates that the imbalanced antagonist/agonist profile of IL-36 cytokines may be linked to SLE pathogenesis. Furthermore, IL-36alpha and IL-36gamma may participate in arthritis and may be good biomarkers of SLE disease activity. PMID- 29571081 TI - Intramuscular and intranasal immunization with an H7N9 influenza virus-like particle vaccine protects mice against lethal influenza virus challenge. AB - The H7N9 influenza virus epidemic has been associated with a high mortality rate in China. Therefore, to prevent the H7N9 virus from causing further damage, developing a safe and effective vaccine is necessary. In this study, a vaccine candidate consisting of virus-like particles (VLPs) based on H7N9 A/Shanghai/2/2013 and containing hemagglutinin (HA), neuraminidase (NA), and matrix protein (M1) was successfully produced using a baculovirus (BV) expression system. Immunization experiments showed that strong humoral and cellular immune responses could be induced by the developed VLPs when administered via either the intramuscular (IM) or intranasal (IN) immunization routes. Notably, VLPs administered via both immunization routes provided 100% protection against lethal infection caused by the H7N9 virus. The IN immunization with 40MUg of H7N9 VLPs induced strong lung IgA and lung tissue resident memory (TRM) cell-mediated local immune responses. These results provide evidence for the development of an effective preventive vaccine against the H7N9 virus based on VLPs administered through both the IM and IN immunization routes. PMID- 29571082 TI - Long-term survival improvement in oesophageal cancer in the Netherlands. AB - BACKGROUND: Treatment for oesophageal cancer has evolved due to developments including the centralisation of surgery and introduction of neoadjuvant treatment. Therefore, this study evaluated trends in stage distribution, treatment and survival of oesophageal cancer patients in the last 26 years in the Netherlands. PATIENTS AND METHODS: Patients with oesophageal cancer diagnosed in the period 1989-2014 were selected from the Netherlands Cancer Registry. Patients were divided into two groups: non-metastatic (M0) and metastatic (M1). Trends in stage distribution, treatment and relative survival rates were evaluated according to histology. RESULTS: Among all 35,760 patients, the percentage of an unknown tumour stage decreased from 34% to 10% during the study period, whereas the percentage of patients with metastatic disease increased from 21% to 34%. Among surgically treated patients 32% underwent a resection in a high-volume hospital in 2005 which increased to 92% in 2014. Use of neoadjuvant chemoradiotherapy increased in non-metastatic oesophageal adenocarcinoma (OAC) and squamous cell carcinoma (OSCC) patients from respectively 4% and 2% in 2000 2004 to 43% and 26% in 2010-2014. Five-year relative survival increased from 8% to 22% for all patients; from 12% to 36% for non-metastatic OAC and from 9% to 27% for non-metastatic OSCC over 26 years. Median overall survival of metastatic patients improved from 18 to 22 weeks. CONCLUSION: In the Netherlands, survival for oesophageal cancer patients improved significantly, especially in the period 2005-2014 which might be the result of better treatment related to the centralisation of surgery and introduction of neoadjuvant chemoradiotherapy. PMID- 29571084 TI - Comprehensive analysis of cancers of unknown primary for the biomarkers of response to immune checkpoint blockade therapy. AB - BACKGROUND: Cancer of unknown primary (CUP) accounts for approximately 3% of all malignancies. Avoiding immune destruction is a major cancer characteristic and therapies aimed at immune checkpoint blockade are in use for several specific cancer types. A comprehensive survey of predictive biomarkers to immune checkpoint blockade in CUP were explored in this study. METHODS: About 389 cases of CUP were analysed for mutations in 592 genes and 52 gene fusions using a massively parallel DNA sequencing platform (next-generation sequencing [NGS]). Total mutational load (TML) and microsatellite instability (MSI) were calculated from NGS data. PD-L1 expression was explored using immunohistochemistry (with 5% cutoff value). RESULTS: High TML was seen in 11.8% (46/389) of tumours. MSI-high (MSI-H) was detected in 7/384 (1.8%) of tumours. Tumour PD-L1 expression was detected in 80/362 CUP (22%). A small proportion of CUP cases harboured genetic alterations of negative predictive biomarkers to immune checkpoint inhibitors (predictors to hyperprogression) including MDM2 gene amplification (2%) and loss of function JAK2 gene mutations (1%). Amplifications of CD274 (PD-L1) and PDCD1LG2 (PD-L2) genes were also rare (1.4% and 0.8%, respectively). The most frequently mutated genes were TP53 (54%), KRAS (22%), ARID1A (13%), PIK3CA (9%), CDKN2A (8%), SMARCA4 (7%) and PBRM1, STK11, APC, RB1 (5%, respectively). CONCLUSIONS: Using a multiplex testing approach, 28% of CUP carried one or more predictive biomarkers (MSI-H, PD-L1 and/or TML-H) to the immune checkpoint blockade, providing a novel option for treatment in patients with CUP. PMID- 29571083 TI - Expression-based intrinsic glioma subtypes are prognostic in low-grade gliomas of the EORTC22033-26033 clinical trial. AB - INTRODUCTION: The European Organisation for Research and Treatment of Cancer (EORTC) 22033-26033 clinical trial (NCT00182819) investigated whether initial temozolomide (TMZ) chemotherapy confers survival advantage compared with radiotherapy (RT) in low-grade glioma (LGG) patients. In this study, we performed gene expression profiling on tissues from this trial to identify markers associated with progression-free survival (PFS) and treatment response. METHODS: Gene expression profiling, performed on 195 samples, was used to assign tumours to one of six intrinsic glioma subtypes (IGSs; molecularly similar tumours as previously defined using unsupervised expression analysis) and to determine the composition of immune infiltrate. DNA copy number changes were determined using OncoScan arrays. RESULTS: We confirm that IGSs are prognostic in the EORTC22033 26033 clinical trial. Specific genetic changes segregate in distinct IGSs: most samples assigned to IGS-9 have IDH-mutations and 1p19q codeletion, samples assigned to IGS-17 have IDH-mutations without 1p19q codeletion and samples assigned to other intrinsic subtypes often are IDH-wildtype. A trend towards benefit from RT was observed for samples assigned to IGS-9 (hazard ratio [HR] for TMZ is 1.90, P = 0.065) but not for samples assigned to IGS-17 (HR 0.87, P = 0.62). We did not identify genes significantly associated with PFS within intrinsic subtypes, although follow-up time is limited. We also show that LGGs and glioblastomas differ in their immune infiltrate, which suggests that LGGs are less amenable to checkpoint inhibitor-type immune therapies. Gene expression analysis also allows identification of relatively rare subtypes. Indeed, one patient with a pilocytic astrocytoma was identified. CONCLUSION: IGSs are prognostic for PFS in EORTC22033-26033 clinical trial samples. PMID- 29571085 TI - Stability of alcohol and tobacco consumption biomarkers in a real rising main sewer. AB - Since alcohol and tobacco consumption are among the leading causes of population health harm, it is very important to understand the consumption behaviour to develop effective harm reduction strategies. Wastewater-based epidemiology (WBE) is a potential tool for estimating their consumption, but there are several uncertainties that need to be determined, including the stability of biomarkers in the sewer. Utilizing a real rising main sewer, this study investigated the stability of alcohol and tobacco consumption biomarkers. Rhodamine and acesulfame were used as flow tracer and benchmarker to understand the transportation of wastewater in the sewer with a hydraulic retention time between 2.7 and 5.0 h. Ethyl sulphate (EtS) and ethyl glucuronide (EtG), two biomarkers of alcohol consumption, were found to have different in-sewer stability, with EtS much more stable than EtG. The degradation rate of EtS is approximately 8% per hour, while EtG has a half-life of 1.9 h. Formation of nicotine, cotinine and trans-3' hydroxycotinine, three biomarkers for tobacco consumption, was observed during the experiment, probably due to deconjugation of their glucuronide chemicals. The deconjugation process has prevented the determination of actual stability of the three chemicals. However, it is suggested that cotinine is relatively stable, while nicotine and trans-3'-hydroxycotinine degrade to a certain degree in the sewer system. According to our findings, the in-sewer degradation is more important during the interpretation of alcohol consumption estimation than for tobacco consumption estimation. PMID- 29571086 TI - Monitoring biofilm function in new and matured full-scale slow sand filters using flow cytometric histogram image comparison (CHIC). AB - While slow sand filters (SSFs) have produced drinking water for more than a hundred years, understanding of their associated microbial communities is limited. In this study, bacteria in influent and effluent water from full-scale SSFs were explored using flow cytometry (FCM) with cytometric histogram image comparison (CHIC) analysis; and routine microbial counts for heterotrophs, total coliforms and Escherichia coli. To assess if FCM can monitor biofilm function, SSFs differing in age and sand composition were compared. FCM profiles from two established filters were indistinguishable. To examine biofilm in the deep sand bed, SSFs were monitored during a scraping event, when the top layer of sand and the schmutzdecke are removed to restore flow through the filter. The performance of an established SSF was stable: total organic carbon (TOC), pH, numbers of heterotrophs, coliforms, E. coli, and FCM bacterial profile were unaffected by scraping. However, the performance of two newly-built SSFs containing new and mixed sand was compromised: breakthrough of both microbial indicators and TOC occurred following scraping. The compromised performance of the new SSFs was reflected in distinct effluent bacterial communities; and, the presence of microbial indicators correlated to influent bacterial communities. This demonstrated that FCM can monitor SSF performance. Removal of the top layer of sand did not alter the effluent water from the established SSF, but did affect that of the SSFs containing new sand. This suggests that the impact of the surface biofilm on effluent water is greater when the deep sand bed biofilm is not established. PMID- 29571087 TI - Pinpointing wastewater and process parameters controlling the AOB to NOB activity ratio in sewage treatment plants. AB - Even though nitrification/denitrification is a robust technology to remove nitrogen from sewage, economic incentives drive its future replacement by shortcut nitrogen removal processes. The latter necessitates high potential activity ratios of ammonia oxidizing to nitrite oxidizing bacteria (rAOB/rNOB). The goal of this study was to identify which wastewater and process parameters can govern this in reality. Two sewage treatment plants (STP) were chosen based on their inverse rAOB/rNOB values (at 20 degrees C): 0.6 for Blue Plains (BP, Washington DC, US) and 1.6 for Nieuwveer (NV, Breda, NL). Disproportional and dissimilar relationships between AOB or NOB relative abundances and respective activities pointed towards differences in community and growth/activity limiting parameters. The AOB communities showed to be particularly different. Temperature had no discriminatory effect on the nitrifiers' activities, with similar Arrhenius temperature dependences (ThetaAOB = 1.10, ThetaNOB = 1.06-1.07). To uncouple the temperature effect from potential limitations like inorganic carbon, phosphorus and nitrogen, an add-on mechanistic methodology based on kinetic modelling was developed. Results suggest that BP's AOB activity was limited by the concentration of inorganic carbon (not by residual N and P), while NOB experienced less limitation from this. For NV, the sludge-specific nitrogen loading rate seemed to be the most prevalent factor limiting AOB and NOB activities. Altogether, this study shows that bottom-up mechanistic modelling can identify parameters that influence the nitrification performance. Increasing inorganic carbon in BP could invert its rAOB/rNOB value, facilitating its transition to shortcut nitrogen removal. PMID- 29571088 TI - Over-focused? The relation between patients' inclination for conscious control and single- and dual-task motor performance after stroke. AB - BACKGROUND: Many stroke patients are inclined to consciously control their movements. This is thought to negatively affect patients' motor performance, as it disrupts movement automaticity. However, it has also been argued that conscious control may sometimes benefit motor performance, depending on the task or patients motor or cognitive capacity. AIM: To assess whether stroke patients' inclination for conscious control is associated with motor performance, and explore whether the putative association differs as a function of task (single- vs dual) or patients motor and cognitive capacity. METHODS: Univariate and multivariate linear regression analysis were used to assess associations between patients' disposition to conscious control (i.e., Conscious Motor Processing subscale of Movement-Specific Reinvestment Scale; MSRS-CMP) and single-task (Timed-up-and-go test; TuG) and motor dual-task costs (TuG while tone counting; motor DTC%). We determined whether these associations were influenced by patients' walking speed (i.e., 10-m-walk test) and cognitive capacity (i.e., working memory, attention, executive function). RESULTS: Seventy-eight clinical stroke patients (<6 months post-stroke) participated. Patients' conscious control inclination was not associated with single-task TuG performance. However, patients with a strong inclination for conscious control showed higher motor DTC%. These associations were irrespective of patients' motor and cognitive abilities. CONCLUSION: Patients' disposition for conscious control was not associated with single task motor performance, but was associated with higher motor dual task costs, regardless of patients' motor or cognitive abilities. CLINICAL RELEVANCE: Therapists should be aware that patients' conscious control inclination can influence their dual-task performance while moving. Longitudinal studies are required to test whether reducing patients' disposition for conscious control would improve dual-tasking post-stroke. PMID- 29571089 TI - Long-term gait outcomes following conservative management of idiopathic toe walking. AB - BACKGROUND: Idiopathic toe walking is a diagnosis of exclusion characterized by a persistent toe-toe gait pattern after three years of age. Treatment for toe walking includes physical therapy, orthotics, casting, Botulinum Toxin A injection into gastrocnemius/soleus muscles, and/or surgery; yet, little evidence exists regarding long-term treatment effects. RESEARCH QUESTION: The objective of this study was to explore the differences in longer-term gait outcomes and severity of idiopathic toe walking between children treated actively with casting or inactively following recommendations for stretching. METHODS: Forty-three adolescents and young adults (14.3-28.8 years; 21 females, 22 males) who had participated in an idiopathic toe walking classification study as children, returned for repeat physical examination and three-dimensional computerized gait analysis (13.4 years follow-up, range 9.4-17.8 years); 23 participants had received active treatment with casting and ankle foot orthotics +/- Botulinum Toxin A injection as children and 20 participants had received inactive treatment with recommended stretching exercises. Gait analysis data were compared retrospectively from baseline to follow-up using analysis of variance; toe walking severity was compared using a Wilcoxin Signed-Rank Sums test. RESULTS: Ankle angle at initial contact, peak dorsiflexion in stance, and toe walking severity improved significantly in the active treatment group only at follow-up. Significant improvement in peak ankle power and timing of ankle kinematics and kinetics in the gait cycle were found in both groups; however, greater changes occurred in the active treatment group. Both groups showed significantly improved internal plantar flexor moments, whereas knee extension increased in stance and passive ankle dorsiflexion decreased in both groups at follow-up (p = 0.001). Intermittent toe walking was reported in 49% (21/43) of participants at follow up. SIGNIFICANCE: The results of this study suggest that improvement in ankle kinematic timing and ankle kinetic gait analysis variables is sustainable, independent of conservative treatment for idiopathic toe walking in childhood. PMID- 29571091 TI - The effect of positive sagittal spine balance and reconstruction surgery on standing balance. AB - BACKGROUND: Positive sagittal spine balance (PSSB) may adversely influence standing balance in individuals with degenerative spine diseases. PSSB is often corrected with the help of spinal reconstructive surgeries involving multiple vertebral units. RESEARCH QUESTION: This study investigated the effect of PSSB and reconstructive surgery on postural sway as a measure of standing balance. The secondary goal of this study was to investigate the effect of reconstructive surgery on lower limb kinematics. METHODS: Subjects who underwent spinal reconstructive surgery for correction of PSSB greater than or equal to 7 cm participated in this study. Postural sway data while standing quietly for 20 s on a force platform were analyzed pre-operatively, 6-12 months and 24 months post operatively. RESULTS: Reconstructive surgery was successful in correcting PSSB in all individuals. There was a moderate correlation between PSSB and postural sway in the anterior-posterior (AP) direction before surgery (r = 0.58) and at 6-12 months post-surgery (r = 0.63). Reconstructive surgery had a significant main effect on postural sway in both the anterior-posterior (p < 0.009, F = 7.01) and medial-lateral directions (p < 0, F = 12.30). Reconstructive surgery also had a significant main effect on standing hip (p < 0, F = 17.01) and knee flexion (p < 0, F = 32.23). SIGNIFICANCE: These results reveal that PSSB in persons with degenerative spinal conditions compromised postural balance, which improved after reconstructive surgery. Additionally, persons with PSSB adopted a crouch posture, which resolved after reconstructive surgery. PMID- 29571090 TI - Impaired set shifting is associated with previous falls in individuals with and without Parkinson's disease. AB - BACKGROUND: Individuals with Parkinson's disease (PD) are at increased risk for falls, which lead to substantial morbidity and mortality. Understanding the motor and non-motor impairments associated with falls in PD is critical to informing prevention strategies. In addition to motor symptoms, individuals with PD exhibit non-motor deficits, including impaired set shifting, an aspect of executive function related to cognitive flexibility that can be measured quickly with the Trailmaking Test. RESEARCH QUESTION: To determine whether impaired set shifting is associated with fall history in people with and without PD. METHODS: We examined associations between set shifting, PD status, and fall history (>=1 falls in the previous 6 months) in data from PD patients (n = 65) with and without freezing of gait (FOG) and community-dwelling neurologically-normal older adults (NON-PD) (n = 73) who had participated in our rehabilitation studies. RESULTS: Impaired set shifting was associated with previous falls after controlling for age, sex, overall cognitive function, PD status, FOG, and PD disease duration (OR = 1.29 [1.03-1.60]; P = 0.02). Consistent with literature, PD and FOG were also independently associated with increased fall prevalence (PD OR = 4.15 [95% CI 1.65-10.44], P < 0.01; FOG OR = 3.63 [1.22-10.80], P = 0.02). Although the strongest associations between set shifting and falling were observed among PD without FOG (OR = 2.11) compared to HOA (OR = 1.14) and PD with FOG (OR = 1.46), no statistically-significant differences were observed across groups. SIGNIFICANCE: Impaired set shifting is associated with previous falls in older adults with and without PD. Set shifting may be useful to include in fall risk assessments, particularly when global cognitive measures are within reference limits. PMID- 29571092 TI - Tm3+-doped lead silicate glass sensitized by Er3+ for efficient ~2MUm mid infrared laser material. AB - Er3+/Tm3+ co-doped lead silicate glasses with low phonon (953cm-1) and good thermal stability were synthesized. The ~2MUm mid-infrared emission resulting from the 3F4->3H6 transition of Tm3+ sensitized by Er3+ has been observed by 808nm LD pumping. The optimal luminescence intensity was obtained in the sample with 1Tm2O3/2.5Er2O3 co-doped. Moreover, the energy transfer mechanism from Er3+ to Tm3+ ion was analyzed. Absorption and emission cross section have been calculated. The calculated maximum emission cross section of Tm3+ is 2.689*10 21cm2 at 1863nm. Microparameters of energy transfer between Er3+ and Tm3+ ions have also been analyzed. These results ensure that the prepared Er3+/Tm3+ co doped lead silicate glasses have excellent spectroscopic properties in mid infrared region and provide a beneficial guide for mid-infrared laser material. PMID- 29571093 TI - Spectral characterization of the fluorescent components present in humic substances, fulvic acid and humic acid mixed with pure benzo(a)pyrene solution. AB - The fate of benzo(a)pyrene (BaP), a ubiquitous contaminant reported to be persistent in the environment, is largely controlled by its interactions with the soil organic matter. In the present study, the spectral characteristics of fluorophores present in the physical fractions of the soil organic matter were investigated in the presence of pure BaP solution. After extraction of humic substances (HSs), and their fractionation into fluvic acid (FA) and humic acid (HA), two fluorescent compounds (C1 and C2) were identified and characterized in each physical soil fraction, by means of fluorescence excitation-emission matrices (FEEMs) and Parallel Factor Analysis (PARAFAC). Then, to each type of fraction having similar DOC content, was added an increasing volume of pure BaP solution in attempt to assess the behavior of BaP with the fluorophores present in each one. The application of FEEMs-PARAFAC method validated a three-component model that consisted of the two resulted fluorophores from HSs, FA and HA (C1 and C2) and a BaP-like fluorophore (C3). Spectral modifications were noted for components C2HSs (C2 in humic substances fraction) (lambdaex/lambdaem: 420/490 520 nm), C2FA (C2 in fulvic acid fraction) (lambdaex/lambdaem: 400/487(517) nm) and C1HA (C1 in humic acid fraction) (lambdaex/lambdaem: 350/452(520) nm). We explored the impact of increasing the volume of the added pure BaP solution on the scores of the fluorophores present in the soil fractions. It was found that the scores of C2HSs, C2FA, and C1HA increased when the volume of the added pure BaP solution increased. Superposition of the excitation spectra of these fluorophores with the emission spectrum of BaP showed significant overlaps that might explain the observed interactions between BaP and the fluorescent compounds present in SOM physical fractions. PMID- 29571094 TI - Suppression of electron spin decoherence in Rabi oscillations induced by an inhomogeneous microwave field. AB - The decay of Rabi oscillations provides direct information about coherence of electron spins. When observed in EPR experiments, it is often shortened by spatial inhomogeneity of the microwave field amplitude in a bulk sample. In order to suppress this undesired loss of coherence, we propose an additional dressing of spin states by a weak longitudinal continuous radiofrequency field. The Gaussian, cosine and linear distributions of the microwave amplitude is analyzed. Our calculations of the Rabi oscillations between the doubly dressed spin states show that for all these distributions the maximum suppression of the inhomogeneity-induced decoherence is achieved at the so-called Rabi resonance when the radio-field frequency is in resonance with the Rabi frequency of spins in the microwave field. The manifestations of such suppression in the published EPR experiments with the bichromatic driving are discussed. The realization of the Rabi resonance using the radiofrequency field could open new possibilities for separating the contributions of relaxation mechanisms from those due to the inhomogeneous driving in spin decoherence. PMID- 29571095 TI - Increasing breast-cancer screening uptake: A randomized controlled experiment. AB - Early screening increases the likelihood of detecting cancer, thereby improving survival rates. National screening programs have been established in which eligible women receive a letter containing a voucher for a free screening. Even so, mammography use is often considered as remaining too low. We test four behavioral interventions in a large-scale randomized experiment involving 26,495 women. Our main assumption is that, due to biases in decision-making, women may be sensitive to the content and presentation of the invitation letter they receive. None of our treatments had any significant impact on mammography use. Sub-sample analysis suggests that this lack of a significant impact holds also for women invited for the first time and low-income women. PMID- 29571096 TI - Sprawling and diverse: The changing U.S. population and implications for public lands in the 21st Century. AB - Public lands are typically established in recognition of their unique ecological value, yet both ecological and social values of public lands change over time, along with human distribution and land use. These transformations are evident even in developed countries with long histories of public land management, such as the United States. The 20th Century saw dramatic changes in the American population, in distribution and in racial and ethnic diversity, leading to new challenges and new roles for public lands. Our goal with this paper is to review changing demographics and implications for terrestrial protected areas in the U.S. We overview the fundamentals of population change and data, review past trends in population change and housing growth and their impacts on public lands, and then analyze the most recent decade of demographic change (2000-2010) relative to public lands. Discussions of demographic change and public lands commonly focus on the rural West, but we show that the South is also experiencing substantial change in rural areas with public lands, including Hispanic population growth. We identify those places, rural and urban, where demographic change (2000-2010), including diversification and housing growth, coincide with public lands. Understanding the current trends and long-term demographic context for recent changes in populations can help land managers and conservation scientists mitigate the effects of residential development near public lands, serve a more diverse population, and anticipate future population changes. PMID- 29571097 TI - Spatially and temporally variable urinary N loads deposited by lactating cows on a grazing system dairy farm. AB - Feed nitrogen (N) intakes in Australian grazing systems average 545 g cow-1 day 1, indicating that urinary N is likely to be the dominant form excreted. Grazing animals spend disproportionate amounts of time in places on dairy farms where N accumulation is likely to occur. We attached to grazing cows sensors that measure urine volume and N concentration, as well as global positioning systems sensors used to monitor the times the cows spent in different places on a farm and the location of urination events. The cows were monitored for up to 72 h in each of two seasons. More urination events and greater urine volumes per event were recorded in spring 2014 (3.1 L) compared with winter 2015 (1.4 L), most likely influenced by environmental conditions and the greater spring rainfall observed. Mean (range) N concentration (0.71%; 0.02 to 1.52%) and N load (12.8 g cow-1 event-1; 0.3 to 64.5 g cow-1 event-1) did not differ over the two monitoring periods. However, mean (range) daily N load was greater in spring (277 g cow-1 day-1; 200 to 346 g cow-1 day-1) than in winter (90 g cow-1 day-1; 44 to 116 g cow-1 day-1) due to the influence of urine volume. Relatively greater time was spent in paddocks overnight (13.3 h) than in paddocks between morning and evening milking (6.4 h), compared with the mean numbers of urinations in these places (6.4 and 3.8 respectively). The mean N load deposited overnight in paddocks (89.6 g cow-1) was more than twice that deposited in paddocks during the day (43.8 g cow-1), due to the greater N load per event overnight, and was more closely linked to the relative difference in time spent in paddocks than in the number of urination events. These data suggest that routinely holding cows in the same paddocks overnight will lead to high urinary N depositions, increasing the potential for N losses from these places. Further research using this technology is required to acquire farm and environment specific urinary data to improve N management.

AB - Among the combustion products, nitrogen oxides are one of the main contributors to a negative impact on the environment, participating in harmful processes such as tropospheric ozone and acid rains production. The main source of emissions of nitrogen oxides is the human combustion of fossil fuels. Their formation models are investigated and implemented with the goal of obtaining a tool for studying the nitrogen-containing pollutant production. In this work, numerical simulation of solid fuel combustion was carried out on a three-dimensional model of a drop tube furnace by using the commercial software FIRE. It was used for simulating turbulent fluid flow and temperature field, concentrations of the reactants and products, as well as the fluid-particles interaction by numerically solving the integro-differential equations describing these processes. Chemical reactions mechanisms for the formation of nitrogen oxides were implemented by the user functions. To achieve reasonable calculation times for running the simulations, as well as efficient coupling with the turbulent mixing process, the nitrogen scheme is limited to sufficiently few homogeneous reactions and species. Turbulent fluctuations that affect the reaction rates of nitrogen oxides' concentration are modelled by probability density function approach. Results of the implemented model for nitrogen oxides' formation from coal and biomass are compared to the experimental data. Temperature, burnout and nitrogen oxides' concentration profiles are compared, showing satisfactory agreement. The new model allows the simulation of pollutant formation in the real-world applications.

AB - In an economic context marked by increasing energy costs and stricter legislation regarding the landfill disposal of wastewater treatment plant (WWTP) sewage sludge, and where biomethanization is difficult to implement in small WWTPs, an efficient alternative is required to manage this polluting waste. This study shows that autothermal thermophilic aerobic digestion (ATAD) is a feasible technique for treating sewage sludge in small- and medium-sized towns. The experiments were carried out at pilot scale on a cyclical basis and in continuous mode for nine months. The main results showed an optimal hydraulic retention time of 7 days, which led to an organic matter removal of 34%. The sanitized sludge meets the microbial quality standards for agronomic application set out in the proposed European sewage sludge directive. An economic assessment for the operation of ATAD technology was carried out, showing a treatment cost of ?6.5/ton for dewatered sludge. PMID- 29571100 TI - Distribution and sources of particulate mercury and other trace elements in PM2.5 and PM10 atop Mount Tai, China. AB - The concentrations of particulate mercury (PHg) and other trace elements in PM2.5 and PM10 in the atmosphere were measured at the summit of Mount Tai during the time period of 15 June - 11 August 2015. The average PHg concentrations were 83.33 +/- 119.1 pg/m3 for PM2.5 and 174.92 +/- 210.5 pg/m3 for PM10. Average concentrations for other trace elements, including Al, Ca, Fe, K, Mg, Na, Pb, As, Se, Cu, Cd, Cr, V, Mo, Co, Ag, Ba, Mn, Zn and Ni ranged from 0.06 ng/m3 (Ag) to 354.33 ng/m3 (Ca) in PM2.5 and 0.11 ng/m3 (Co) to 592.66 ng/m3 (Ca) in PM10. The average concentrations of PHg were higher than those at other domestic mountain sites and cities in other counties, lower than those at domestic city sites. Other trace elements showed concentrations lower than those at the domestic mountain sites. Due possibly to increased control of emissions and the proportion of new energy, the PHg and trace element concentrations decreased, but the PHg showed concentrations higher than those at the Mountain sites, this showed that the reasons was not only severely affected by anthropogenic emissions, but also associated with other sources. The concentration changed trend of the main trace elements indicated that PHg, trace elements and particle matters present positive correlation and fine particulate matter has a greater surface area which was conductive to adsorption of Hg and trace elements to particles. On June 19, June 27 and July 6, according to the peak of mercury and trace elements, we can predict the potential sources of these three days. The results of principal component analysis (PCA) suggested that, crustal dust, coal combustion, and vehicle emissions were the main emission sources of PHg and other trace elements in Mount Tai. The 24-h backward trajectories and potential source contribution function (PSCF) analysis revealed that air masses arriving at Mount Tai were mainly affected by Shandong province. Mount Tai was subjected to five main airflow trajectories. Clusters 1, 2, 3, and 5 represented four pathways for local and regional sources and cluster 4 originated long-distance transportation. Central Shandong was the main source regions of PHg, Pb, Se, As, Cu and Cd. Southeastern and northwestern Shandong province and northern Jiangsu province were the most polluted source regions of Mn, Zn, and Ni. The crustal elements Fe and Ca had similar distributions of potential source regions, suggested by the highest PSCF values in southeastern Shandong and northern Jiangsu. PMID- 29571101 TI - Importance of hydrophobic interactions in the single-chained cationic surfactant DNA complexation. AB - The goal of this work was to understand the key factors determining the DNA compacting capacity of single-chained cationic surfactants. Fluorescence, zeta potential, circular dichroism, gel electrophoresis and AFM measurements were carried out in order to study the condensation of the nucleic acid resulting from the formation of the surfactant-DNA complexes. The apparent equilibrium binding constant of the surfactants to the nucleic acid, Kapp, estimated from the experimental results obtained in the ethidium bromide competitive binding experiments, can be considered directly related to the ability of a given surfactant as a DNA compacting agent. The plot of ln(Kapp) vs. ln(cmc), cmc being the critical micelle concentration, for all the bromide and chloride surfactants studied, was found to be a reasonably good linear correlation. This result shows that hydrophobic interactions mainly control the surfactant DNA compaction efficiency. PMID- 29571102 TI - Role of CuO in improving NH3 and SO2 capture on nanoporous Fe2O3 sorbents. AB - In this work, mixed Fe/Cu oxides as sorbents for SO2 and NH3 removal were investigated. Nanoporous iron oxide mixed with 10, 20 and 30 at.% CuO were prepared by thermal decomposition of the corresponding oxalates at 250 degrees C for 5 h in air. The mixed Fe/Cu oxalates were obtained from the co-precipitation of iron/copper sulfate and ammonium oxalate during ultrasonication. The physical properties of the oxalate precursors and the resulting mixed Fe/Cu oxides were characterized with SEM, TGA-DSC, FTIR, powder XRD and Mossbauer spectroscopy. The porosity was studied by N2 adsorption-desorption isotherms and small angle X-ray scattering. Evenly dispersed CuO hindered the crystallization of Fe2O3, which significantly increased the specific BET surface area from 211 m2/g for Fe2O3 to 354 m2/g for Fe0.8Cu0.2Ox. As a result, SO2 and NH3 adsorption on Fe0.8Cu0.2Ox were enhanced by about 70% compared to Fe2O3. Compared to Fe2O3-impregnated activated carbons, nanoporous Fe0.8Cu0.2Ox could capture five times more SO2 per unit weight, which will be attractive for applications in respirators with lower weight and smaller size. PMID- 29571103 TI - TiO2 nanocrystals decorated Z-schemed core-shell CdS-CdO nanorod arrays as high efficiency anodes for photoelectrochemical hydrogen generation. AB - TiO2 nanocrystals decorated core-shell CdS-CdO nanorod arrays, TiO2@CdO/CdS NR, were fabricated as high efficiency anodes for photoelctrochemical hydrogen generation. The novel sandwich heterostructure was constructed from first growth of CdS nanorod arrays on a fluorine doped tin oxide (FTO) substrate with a hydrothermal process, followed by in situ generation of CdO thin films of single digit nanometers from the CdS nanorod surfaces through thermal oxidation, and final decoration of TiO2 nanocrystals of 10-20 nm via a successive ionic layer absorption and reaction process. The core-shell CdS-CdO heterostructure possesses a Z-scheme band structure to enhance interfacial charge transfer, facilitating effective charge separation to suppress electron-hole recombination within CdS for much improved current density generation. The final decoration of TiO2 nanocrystals passivates surface defects and trap states of CdO, further suppressing surface charge recombination for even higher photovoltaic conversion efficiencies. The photoelectrochemical performances of the plain CdS nanorod array were significantly improved with the formation of the sandwich heterostructure, achieving a photo current density of 3.2 mA/cm2 at 1.23 V (vs. RHE), a 141% improvement over the plain CdS nanorod array and a 32% improvement over the CdO/CdS nanorod array. PMID- 29571104 TI - Saturated imbibition under the influence of gravity and geometry. AB - HYPOTHESIS: The effect of gravity was generally neglected in the classical imbibition law for one dimensional geometries. Following researches complemented the classical "Lucas-Washburn law" with consideration of gravity, but no examination of geometries under influence of gravity has been done, while geometry was shown to yield different scaling law for the imbibition process. Hence, it is possible to discover new time exponents for imbibition length in two dimensional and three dimensional imbibition process under gravity. METHODS: Through theoretical analysis and numerical simulations, the size of wetted region under three gravitational scenarios (zero gravity, acceleration and deceleration) in three geometries (one dimensional, two dimensional radial and three dimensional radial) are determined quantitatively. FINDINGS: New time exponents other than classic 1/2 are identified under different directions of gravity in two dimensional radial and three dimensional radial imbibition, and symmetry of time exponents due to different directions of gravity is discovered. A new time exponent of 1 for the acceleration case in one dimensional imbibition is found. The flow field in the wetted region is also determined from simulations. Discoveries in this paper show that new physical laws for imbibition length exist at the intersection of gravity and geometry. PMID- 29571105 TI - Superparamagnetic silica core-shell hybrid attached to graphene oxide as a promising recoverable catalyst for expeditious synthesis of TMS-protected cyanohydrins. AB - Fe3O4/SiO2 core-shell hybrid nanoparticles covalently attached to graphene oxide (Fe3O4/SiO2/PTS-GO) were prepared and fully characterized using different techniques including Fourier transform infrared (FTIR) spectroscopy, X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) spectroscopy, transmission electron microscopy (TEM) and atomic force microscopy (AFM). The efficiency of Fe3O4/SiO2/PTS-GO nanocomposite was demonstrated in trimethylsilyl cyanide (TMSCN) addition to a wide range of aldehydes and ketones in high to quantitative yields under extremely mild conditions. Low catalyst loading, reusability of the catalyst, avoiding the use of any hazardous solvent, short reaction time at ambient temperature and straightforward work up procedure are some of the attractive advantages of this protocol. PMID- 29571106 TI - Transition support for new graduate and novice nurses in critical care settings: An integrative review of the literature. AB - Transition into critical care areas for new graduate nurses may be more difficult than transitioning into other areas due to the specialised knowledge needed. It is unknown which aspects of transition programs best support new graduate nurses improve competence and confidence to transition into critical care nursing specialties. Identifying these aspects would assist to design and implement best practice transition programs for new graduates in critical care areas. Themes identified in the literature include; having a designated resource person, workplace culture, socialisation, knowledge and skill acquisition, orientation, and rotation. Allocation of a quality resource person/s, supportive workplace culture, positive socialisation experiences, knowledge and skill acquisition and structured orientation based on new graduates' learning needs all positively supported increased confidence, competence and transition into nursing practice. Rotations between areas within graduate programs can potentially have both positive and negative impacts on the transition process. Negative impacts of including a rotation component in a transition program should be carefully considered alongside perceived benefits when designing new graduate nurse transition programs. PMID- 29571107 TI - Adsorption behavior of Ni(II) onto activated carbons from hide waste and high pressure steaming hide waste. AB - This work reports the preparation and adsorption of Ni(II) via activated carbons which produced from hide waste (HWAC) and high-pressure steaming hide waste (HWSAC) with potassium silicate as the activating agent. The best preparation condition for HWAC and HWSAC was the activation temperature of 700 degrees C using an impregnation ratio of 2:1. Both of them were characterized by N2 adsorption/desorption isotherms, SEM and FT-IR spectra. The surface area of HWAC and HWSAC was 1804.37 and 1361.26 m2/g, respectively. Despite the surface area of HWAC being larger than that of HWSAC, but the adsorption capacity of Ni(II) for HWAC was lower than that for HWSAC. Furthermore, the adsorption capacity of Ni(II) for both HWAC and HWSAC showed pH-dependent behavior and increased with the increase in pH value, which can be attributed to the functional groups of HWAC and HWSAC materials through the electrostatic attraction. The adsorption data for HWAC and HWSAC were fitted with four isotherm models (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich) and four kinetic models (pseudo first order model, pseudo-second order model, intra-particle diffusion and Elovich equation), indicating that Langmuir isotherm and Pseudo-second order model fitted well with high coefficient of determination (R2 > 0.99) for both the two adsorbents. The positive enthalpy of adsorption (DeltaH) and free energy of adsorption (DeltaG) indicate a spontaneous and endothermic nature of the process. These results demonstrated that activated carbon can be prepared from hide waste which could remove heavy metal such as Ni(II) effectively. PMID- 29571108 TI - Effects of dietary Pb and Cd and their combination on lysosomal and tissue-level biomarkers and histopathology in digestive gland of the land snail, Cantareus apertus (Born, 1778). AB - The present study was aimed at determining cell and tissue-level biomarkers and histopathological alterations in the green garden snail, Cantareus apertus (Born, 1778), exposed to different nominal dietary concentrations of Pb (25, 100 and 2500 mg Pb/kg), Cd (5, 10 and 100 mg Cd/kg) and their combination (25 mg Pb + 5 mg Cd/Kg, 100 mg Pb + 10 mg Cd/kg and 2500 mg Pb + 100 mg Cd/ kg) for 1 and 8 weeks. Lead and Cd exerted histopathological effects on the digestive gland in a dose-dependent manner and related to lysosomal and tissue-level biomarkers. The biological responses observed included digestive cell vacuolisation and numerical atrophy, calcium cell hydropic degeneration, excretory cell hypertrophy, inflammatory responses, blood vessel congestion, and disruption of the blood vessel wall and the interstitial connective tissue. Lysosomal enlargement and transient intracellular accumulation of neutral lipids and lipofuscins were also observed, together with alterations in the cell type composition and thinning of the digestive gland epithelium and with diverticular distortion. This response profile fits well with the biological effects reported after metal exposure in gastropods from other regions, as well as with data obtained in parallel studies dealing with metal bioaccumulation and intralysosomal accumulation, mortality, feeding, growth, oxidative stress and neurotoxicity exerted elicited by Pb, Cd and their mixture in green garden snails under the present experimental conditions. Consequently, C. apertus seems to be a suitable model species for the biomarker-based assessment of the biological effects of Pb and Cd, alone or in combinations, thus providing a challenging opportunity to advance in identifying suitable sentinel species for metal pollution biomonitoring and ecosystem health assessment in soil ecosystems in Northern Africa. PMID- 29571109 TI - Yucca schidigera extract modulates the lead-induced oxidative damage, nephropathy and altered inflammatory response and glucose homeostasis in Japanese quails. AB - The present study was conducted to explore the toxic effects of lead (Pb) on the physiological responses of Japanese quails and to investigate the potential modulatory role of Yucca schidigera extract (YSE) against these effects. 360 mature Japanese quails (at 2 months of age) were used and the experiment was lasted for 8 weeks. The birds were divided into six equal groups as follow: control (basal diet, BD), BD+Pb (100 mg/kg diet), BD+YSE (100 mg/kg diet), BD+YSE (200 mg/kg diet), BD+Pb (100 mg/kg diet) +YSE (100 mg/kg diet) and BD+ Pb (100 mg/kg diet) + YSE (200 mg/kg diet). Pb induced a significant reduction in superoxide dismutase (SOD) and catalase (CAT) activities and reduced glutathione (GSH) level. While, increased protein carbonyl (PC) and malondialdehyde (MDA) content in tissues of exposed birds. Pb increased level of 8-hydroxy-2 deoxyguanosine (8-OHdG) and lactate dehydrogenase (LDH) activity in serum. YSE significantly reduced the Pb -induced oxidative stress in co-treated groups especially at 200 mg/kg diet. YSE could modulate the Pb -induced decreased urea, creatinine and beta-2 microglobulin (B2M) levels. YSE200 was found to be better than the YSE100 in decreasing levels of inflammatory markers including tumor necrosis factor (TNF-alpha), nitric oxide (NO), transforming growth factor-beta1 (TGF-beta1) and vascular endothelial growth factor (VEGF). Furthermore, YSE significantly regulates glucose homeostasis in co-exposed quails. Pb residues were found to be significantly higher in kidney and pancreas tissues of Pb group compared to other groups. YES decreased the expression of metallothionein-1 in the renal and pancreatic tissues, while elevated insulin expression in the pancreatic cells by immunostaining in co-exposed groups. In conclusion, the present results conclusively demonstrate the potential modulatory effect of YSE against the Pb-induced toxic effects in different organs of Japanese quails. PMID- 29571110 TI - Spatial variation of polycyclic aromatic hydrocarbons (PAHs) in surface sediments from rivers in hilly regions of Southern China in the wet and dry seasons. AB - Seasonal variations of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments from 13 rivers in hilly regions of southern China were studied. Concentrations of PAHs analyzed in the wet season were higher than those analyzed in the dry season, with residues ranging from 74.3 to 1930.9 ng g-1 dw in the wet season and from 96.9 to 1388.9 ng g-1 dw in the dry season. The primary contributors were 3- and 4-ringed congeners accounting for 59.8% +/- 10.1% and 58.3% +/- 9.3% of the identified PAHs in the wet and the dry seasons, respectively. Proximity to sources and locations susceptible to high atmospheric depositional inputs results in high concentrations of PAH. Diagnostic ratios have indicated that the sources of PAHs in different seasons make no apparent difference. Furthermore, a principal component analysis and multiple linear regression (PCA-MLR) studies indicate that combustion sources such as vehicle emissions and coal combustion are the primary sources of PAHs. Toxicological risk assessments based on TEQcare suggested that Benzo[a]pyrene, benz[a]anthracene, dibenz[a,h]anthracene could pose high ecological risks in this area. PMID- 29571111 TI - Spatial patterns of pharmaceuticals and wastewater tracers in the Hudson River Estuary. AB - The widespread use of pharmaceuticals by human populations results in their sustained discharge to surface waters via wastewater treatment plants (WWTPs). In this study, 16 highly prescribed pharmaceuticals were quantified along a 250 km transect of the Hudson River Estuary and New York Harbor to describe their sources and spatial patterns. Sampling was conducted over two dry weather periods in May and July 2016, at 72 sites which included mid-channel and nearshore sites, as well as locations influenced by tributaries and WWTP outfalls. The detection frequency of the study pharmaceuticals was almost identical between the May and July sampling periods at 55% and 52%, respectively. Six pharmaceuticals were measurable at 92% or more of the sites during both sampling periods, illustrating their ubiquitous presence throughout the study area. Individual pharmaceutical concentrations were highly variable spatially, ranging from non-detect to 3810 ng/L during the study. Major factors controlling concentrations were proximity and magnitude of WWTP discharges, inputs from tributaries and tidal mixing. Two compounds, sucralose and caffeine, were evaluated as tracers to identify wastewater sources and assess pharmaceutical behavior. Sucralose was useful in identifying wastewater inputs to the river and concentrations showed excellent correlations with numerous pharmaceuticals in the study. Caffeine-sucralose ratios showed potential in identifying discharges of untreated wastewater occurring during a combined sewage overflow event. Many of the study pharmaceuticals were present throughout the Hudson River Estuary as a consequence of sustained wastewater discharge. Whereas some concentrations were above published effects levels, a more complete risk assessment is needed to understand the potential for ecological impacts due to pharmaceuticals in the Hudson River Estuary.

AB - Nitrogen (N) transport from land to water is a dominant contributor of N in estuarine waters leading to eutrophication, harmful algal blooms, and hypoxia. Our objectives were to (1) investigate the composition of inorganic and organic N forms, (2) distinguish the sources and biogeochemical mechanisms of nitrate-N (NO3-N) transport using stable isotopes of NO3- and Bayesian mixing model, and (3) determine the dissolved organic N (DON) bioavailability using bioassays in a longitudinal gradient from freshwater to estuarine ecosystem located in the Tampa Bay, Florida, United States. We found that DON was the most dominant N form (mean: 64%, range: 46-83%) followed by particulate organic N (PON, mean: 22%, range: 14-37%), whereas inorganic N forms (NOx-N: 7%, NH4-N: 7%) were 14% of total N in freshwater and estuarine waters. Stable isotope data of NO3- revealed that nitrification was the main contributor (36.4%), followed by soil and organic N sources (25.5%), NO3- fertilizers (22.4%), and NH4+ fertilizers (15.7%). Bioassays showed that 14 to 65% of DON concentrations decreased after 5-days of incubation indicating utilization of DON by microbes in freshwater and estuarine waters. These results suggest that despite low proportion of inorganic N forms, the higher concentrations and bioavailability of DON can be a potential source of N for algae and bacteria leading to water quality degradation in the estuarine waters. PMID- 29571113 TI - Synthesis of stable benzimidazole derivatives bearing pyrazole as anticancer and EGFR receptor inhibitors. AB - A new series of benzimidazole linked pyrazole derivatives were synthesized by cyclocondensation reaction through one-pot multicomponent reaction in absolute ethanol. All the synthesized compounds were tested for their in vitro anticancer activities on five human cancer cell lines including MCF-7, HaCaT, MDA-MB231, A549 and HepG2. EGFR receptor inhibitory activities were carried out for all the compounds. Majority of the compounds showed potent antiproliferative activity against the tested cancer cell lines. Compound 5a showed the most effective activity against the lungs cancer cell lines (IC50 = 2.2 uM) and EGFR binding (IC50 = 0.97 uM) affinity as compared to other members of the series. Compound 5a inhibited growth of A549 cancer cells by inducing a strong G2/M phase arrest. In addition, same compound inhibited growth of A549 cancer cells by inducing apoptosis. In molecular docking studies compound 5a was bound to the active pocket of the EGFR (PDB 1M17) with five key hydrogen bonds and two pi-pi interaction with binding energies DeltaG = -34.581 Kcal/mol. PMID- 29571114 TI - Mechanically strong dual responsive nanocomposite double network hydrogel for controlled drug release of asprin. AB - Mechanically strong dual/multi-stimuli-responsive smart hydrogels have attracted extensive attention in recent years. A novel tough, mechanical strong and biocompatible dual pH- and temperature- responsive poly (N-isopropylacrylamide) /clay (laponite XLG)/carboxymethyl chitosan (CMCTs) /genipin nanocomposite double network hydrogel was synthesized through a facile, one-pot free radical polymerization initiated by the ultraviolet light, using clay and the natural molecular-genipin as the cross-linkers instead of toxic organic molecules. Crucial factors, the content of CMCTs, clay and genipin, for synthesizing the mechanical strong hydrogels were investigated. When the content of CMCTs, clay and genipin were 5 wt%, 33.3 wt% and 0.175 wt%, respectively (to the weight of N isopropylacrylamide), these prepared hydrogels exhibited a high tensile strength of 137.9 kPa at the failure strain of 446.1%. Furthermore, the relationship between swelling and deswelling rate of the synthesized hydrogels and the above crucial factors were also studied. Besides, the synthesized hydrogels displayed a considerable controlled release property of asprin by tuning their inner crosslink density. Owing to this property, they may have great potential in the drug delivery systems. PMID- 29571115 TI - Compressive fatigue properties of commercially available standard and low-modulus acrylic bone cements intended for vertebroplasty. AB - Vertebroplasty (VP) is a minimally invasive surgical procedure commonly used to relieve severe back pain associated with vertebral compression fractures. The poly(methyl methacrylate) bone cement used during this procedure is however presumed to facilitate the occurrence of additional fractures next to the treated vertebrae. A reason for this is believed to be the difference in stiffness between the bone cement and the surrounding trabecular bone. The use of bone cements with lower mechanical properties could therefore reduce the risk of complications post-surgery. While intensive research has been performed on the quasi-static mechanical properties of these cements, there is no data on their long-term mechanical properties. In the present study, the in vitro compressive fatigue performance as well as quasi-static mechanical properties of two commercially available acrylic bone cements - a low-modulus cement (Resilience(r)) and a standard cement (F20) from the same manufacturer - were determined. The quasi-static mechanical properties of the low-modulus and standard cements after 24 h of setting were in the range of other vertebroplastic cements (sigma = 70-75 MPa; E= 1600-1900 MPa). F20 displayed similar mechanical properties over time in 37 degrees C phosphate buffered saline solution, while the mechanical properties of the Resilience(r) cement decreased gradually due to an increased porosity in the polymeric matrix. The standard cement exhibited a fatigue limit of approx. 47 MPa, whereas the low-modulus cement showed a fatigue limit of approx. 31 MPa. In summary, the low-modulus bone cement had a lower fatigue limit than the standard cement, as expected. However, this fatigue limit is still substantially higher than the stresses experienced by vertebral trabecular bone. PMID- 29571116 TI - The critically ill patient with tuberculosis in intensive care: Clinical presentations, management and infection control. AB - Tuberculosis (TB) is one of the top ten causes of death worldwide. In 2016, there were 490,000 cases of multi-drug resistant TB globally. Over 2 billion people have asymptomatic latent Mycobacterium tuberculosis infection. TB represents an important, but neglected management issue in patients presenting to intensive care units. Tuberculosis in intensive care settings may present as the primary diagnosis (active drug sensitive or resistant TB disease). In other patients TB may be an incidental co-morbid finding as previously undiagnosed sub-clinical or latent TB which may re-activate under conditions of stress and immunosuppression. In Sub-Saharan Africa, where co-infection with the human immunodeficiency virus and other communicable diseases is highly prevalent, TB is one of the most frequent clinical management issues in all healthcare settings. Acute respiratory failure, septic shock and multi-organ dysfunction are the most common reasons for intensive care unit admission of patients with pulmonary or extrapulmonary TB. Poor absorption of anti-TB drugs occurs in critically ill patients and worsens survival. The mortality of patients requiring intensive care is high. The majority of early TB deaths result from acute cardiorespiratory failure or septic shock. Important clinical presentations, management and infection control issues regarding TB in intensive care settings are reviewed. PMID- 29571117 TI - Fabric phase sorptive extraction-high performance liquid chromatography-photo diode array detection method for simultaneous monitoring of three inflammatory bowel disease treatment drugs in whole blood, plasma and urine. AB - This paper reports a novel fabric phase sorptive extraction-high performance liquid chromatography-photodiode array detection (FPSE-HPLC-PDA) method for the simultaneous extraction and analysis of three drug residues (ciprofloxacin, sulfasalazine, and cortisone) in human whole blood, plasma, and urine samples, generally administered in human patients to treat inflammatory bowel disease (IBD). The drugs of interest were well resolved using a Luna C18 column (250 mm * 4.6 mm; 5 MUm particle size) in gradient elution mode within 20 min. The analytical method was optimized and validated in the range 0.05-10 MUg/mL for whole blood, 0.25-10 MUg/mL for human plasma, and 0.10-10 MUg/mL for human urine. Blank human whole blood, plasma, and urine were used as the sample matrix for the method development and validation; while methyl-p-hydroxybenzoate was used as the internal standard (IS). Weighted-matrix matched standard calibration curves showed a good linearity up to a concentration of 10 MUg/mL. The intra- and inter day accuracy values (precision and trueness) were found in the range from -10.9% to 12.3%, and the performances of the validated FPSE-HPLC-PDA were further tested on real IBD patient samples. This is the first FPSE procedure applied simultaneously to whole blood, plasma, and urine samples for the determination of residual IBD drugs, which possess a wide range of polarity (logP values ranging from 2.30 for Ciprofloxacin, to 1.66 for Cortisone, and 2.92 for Sulfasalazine). The new approach exhibits high potential for immediate adoptation as a rapid, robust and green analytical tool for future clinical and pharmaceutical applications. PMID- 29571118 TI - Analysis of 10 beta-agonists in pork meat using automated dispersive pipette extraction and LC-MS/MS. AB - An analytical procedure for the analysis of 10 beta-adrenergic agonists (cimaterol, terbutaline, salbutamol, isoxsuprine, ractopamine, cimbuterol, clenbuterol, brombuterol, mabuterol and mapenterol) in pork meat was developed and validated using LC-MS/MS. An automated dispersive pipette extraction (DPX) was employed on a Hamilton Microlab(r) NIMBUS96(r) platform to extract the analytes of interest prior to LC-MS/MS analysis. The extraction time was <20 min with a total LC-MS/MS run time of 9.6 min. The method was fully validated in accordance with the international guidelines (European Commission Decision 2002/657/EC and National Standards of People's Republic of China, GB/T 22286 2008) for limit of detection, limit of quantitation, carryover, extraction efficiency, matrix effects, linearity, and within and between-run precision. The proposed method can be successfully used in the routine determination of 10 beta adrenergic agonists in pork and as a potential solution for compliance monitoring in regulatory laboratories.

Here, we report quantitative profiling of the phosphometabolome by applying capillary ion chromatography-tandem mass spectrometry (capIC-MS/MS), ensuring improved chromatographic separation, robustness and quantitative precision. Baseline separation was achieved for six out of eight tested hexose phosphates. Quantitative precision and reproducibility was improved by introducing a fully uniformly (U) 13C-labeled biological extract and applying an isotope dilution (ID) correction strategy. A 13C-labeled biological extract does in principle contain internal standards (IS) for all metabolites, but low abundant metabolites pose a challenge, and solutions to this are discussed. The extreme reproducibility and reliability of this capIC-MS/MS method was demonstrated by running the instrumentation continuously for ten days. PMID- 29571120 TI - Emotion identification and aging: Behavioral and neural age-related changes. AB - OBJECTIVE: Aging is known to alter the processing of facial expressions of emotion (FEE), however the impact of this alteration is less clear. Additionally, there is little information about the temporal dynamics of the neural processing of facial affect. METHODS: We examined behavioral and neural age-related changes in the identification of FEE using event-related potentials. Furthermore, we analyze the relationship between behavioral/neural responses and neuropsychological functioning. To this purpose, 30 younger adults, 29 middle aged adults and 26 older adults identified FEE. RESULTS: The behavioral results showed a similar performance between groups. The neural results showed no significant differences between groups for the P100 component and an increased N170 amplitude in the older group. Furthermore, a pattern of asymmetric activation was evident in the N170 component. Results also suggest deficits in facial feature decoding abilities, reflected by a reduced N250 amplitude in older adults. Neuropsychological functioning predicts P100 modulation, but does not seem to influence emotion identification ability. CONCLUSIONS: The findings suggest the existence of a compensatory function that would explain the age equivalent performance in emotion identification. SIGNIFICANCE: The study may help future research addressing behavioral and neural processes involved on processing of FEE in neurodegenerative conditions. PMID- 29571121 TI - Prediction of secondary generalization from a focal onset seizure in intracerebral EEG. AB - OBJECTIVE: We propose a system based on the first five seconds of intracerebrally recorded focal seizures to predict their evolution from focal to bilateral tonic clonic seizure (FTC), to spread outside the onset zone but without tonic-clonic component (FS), or to a seizure remaining focal (F). METHODS: Nineteen time and frequency domain features were extracted from 39 seizures of 32 patients and were subjected to support vector machine based classification. Three prediction approaches regarding seizure evolution were (1) FTC vs FS vs F, (2) FTC vs FS or F and (3) FTC or FS vs F. RESULTS: We used 21 seizures for training. Most features had significantly different distributions in the three seizure types (p < 0.05). Eighteen seizures were used for testing. We predicted the evolution of 12 seizures in FTC vs FS vs F, 13 seizures in FTC vs FS or F and 14 seizures in FTC or FS vs F. CONCLUSION: The first five seconds of a focal seizure contains information regarding the eventual evolution of the seizure, which could be predicted in most seizures. SIGNIFICANCE: The proposed system could alert the health care team when a patient is hospitalized for intracerebral EEG and improve safety and eventually result in an implantable device. PMID- 29571122 TI - Connectivity inference from neural recording data: Challenges, mathematical bases and research directions. AB - This article presents a review of computational methods for connectivity inference from neural activity data derived from multi-electrode recordings or fluorescence imaging. We first identify biophysical and technical challenges in connectivity inference along the data processing pipeline. We then review connectivity inference methods based on two major mathematical foundations, namely, descriptive model-free approaches and generative model-based approaches. We investigate representative studies in both categories and clarify which challenges have been addressed by which method. We further identify critical open issues and possible research directions. PMID- 29571123 TI - Implementation of the RCOG guidelines for prevention of obstetric anal sphincter injuries (OASIS) at two London Hospitals: A time series analysis. AB - OBJECTIVE: To audit the impact of implementation of the RCOG guidelines for prevention of Obstetric anal sphincter injuries (OASIS) by introducing antenatal perineal massage, manual perineal protection, and cutting episiotomies at 60 degrees to the midline at the time of crowning. DESIGN: Time series analysis; Setting - Two London teaching hospitals; Royal Free London (RFL) and Barnet; Population or Sample - All nulliparous women undergoing vaginal birth; Methods - Training was provided for above techniques. EPISCISSORS-60 were introduced to perform 60 degrees episiotomies. Data were extracted from maternity databases and dashboards; Main Outcome Measures - OASIS rates before and after implementation. RESULTS: Data from 2566 births were analysed. In operative vaginal deliveries (OVD), OASIS declined from 9.6% to 2% (p = 0.001) at Barnet and from 5.6% to 4.2% (p = 0.4) at RFL. OASIS reduced in nulliparous OVD's given episiotomies from 6.3% in the 'before' period to 0.6% in the 'after' period [p = 0.01] at Barnet. Before introduction of the EPISCISSORS-60, OASIS rate was 6.3% with episiotomies and 30% without episiotomies (p = 0.000). After introduction of the EPISCISSORS-60, OASIS rate was 0.63% with episiotomies v 16% without episiotomies (p = 0.000) at Barnet. At RFL, OASIS rate was 2.6% with episiotomies, and 42% without episiotomy (p = 0.000). In SVD's at Barnet, OASIS declined from 6.6% before to 0% after (p = 0.000) in women given episiotomies while it declined from 5.4% to 3% (p = 0.12) in those not given episiotomies. After introduction of the EPISCISSORS-60, OASIS was 0% in women with episiotomies and 3% in those without episiotomies (p = 0.04). In SVD's at RFL, OASIS was 0% in women given episiotomy v 4.7% without episiotomy (p = 0.03). CONCLUSIONS: Deliveries with EPISCISSORS-60 episiotomies had lesser OASIS than those without episiotomies in both nulliparous OVD's and SVD's. OASIS was lower with EPISCISSORS-60 episiotomies than those with eyeballed episiotomies. PMID- 29571124 TI - Prevention and management of genital herpes simplex infection during pregnancy and delivery: Guidelines from the French College of Gynaecologists and Obstetricians (CNGOF). AB - OBJECTIVE: Identify measures to diagnose, prevent, and treat genital herpes infection during pregnancy and childbirth as well as neonatal herpes infection. MATERIALS AND METHODS: Bibliographic search from the Medline and Cochrane Library databases and review of international clinical practice guidelines. RESULTS: Genital herpes lesions are most often due to HSV-2 (LE2). The risk of HSV seroconversion during pregnancy is 1-5% (LE2). Genital herpes lesions during pregnancy in a woman with a history of genital herpes is a recurrence. In this situation, there is no need for virologic confirmation (Grade B). In pregnant women with genital lesions who report they have not previously had genital herpes, virological confirmation by PCR and identifying the specific IgG type is necessary (professional consensus). A first episode of genital herpes during pregnancy should be treated with aciclovir (200 mg 5 times daily) or valaciclovir (1000 mg twice daily) for 5-10 days (Grade C), and recurrent herpes during pregnancy with aciclovir (200 mg 5 times daily) or valaciclovir (500 mg twice daily) (Grade C). The risk of neonatal herpes is estimated at between 25% and 44% if a non primary and primary first genital herpes episode is ongoing at delivery (LE2) and 1% for a recurrence (LE3). Antiviral prophylaxis should be offered to women with either a first or recurrent episode of genital herpes during pregnancy from 36 weeks of gestation until delivery (Grade B). Routine prophylaxis is not recommended for women with a history of genital herpes but no recurrence during pregnancy (professional consensus). A cesarean delivery is recommended if a first episode of genital herpes is suspected (or confirmed) at the onset of labor (Grade B) or if it occured less than 6 weeks before delivery (professional consensus) or in the event of premature rupture of the membranes at term. When a recurrence of genital herpes is underway at the onset of labor, cesarean delivery is most likely to be considered when the membranes are intact and vaginal delivery in cases of prolonged rupture of membranes (professional consensus). Neonatal herpes is rare and mainly due to HSV-1 (LE3). In most cases of neonatal herpes, mothers have no history of genital herpes (LE3). When neonatal herpes is suspected, various samples (blood and cerebrospinal fluid) for HSV PCR must be taken to confirm the diagnosis (professional consensus). Any newborn with suspected neonatal herpes should be treated with intravenous acyclovir (20 mg/kg 3 times daily) (grade A) before the PCR results are available (professional consensus). The duration of the treatment depends on the clinical form (professional consensus) CONCLUSION: There is no formal evidence that it is possible to reduce the risk of neonatal herpes in genital herpes during pregnancy. However, appropriate care can reduce the symptoms associated with herpes and the risk of recurrence at term, as well as cesarean rate because of herpes lesions. PMID- 29571126 TI - Development of an integrated model for energy systems planning and carbon dioxide mitigation under uncertainty - Tradeoffs between two-level decision makers. AB - A bi-level fuzzy programming (BFLP) method was developed for energy systems planning (ESP) and carbon dioxide (CO2) mitigation under uncertainty. BFLP could handle fuzzy information and leader-follower problem in decision-making processes. It could also address the tradeoffs among different decision makers in two decision-making levels through prioritizing the most important goal. Then, a BFLP-ESP model was formulated for planning energy system of Beijing, in which the upper-level objective is to minimize CO2 emission and the lower-level objective is to minimize the system cost. Results provided a range of decision alternatives that corresponded to a tradeoff between system optimality and reliability under uncertainty. Compared to the single-level model with a target to minimize system cost, the amounts of pollutant/CO2 emissions from BFLP-ESP were reduced since the study system would prefer more clean energies (i.e. natural gas, LPG and electricity) to replace coal fuel. Decision alternatives from BFLP were more beneficial for supporting Beijing to adjust its energy mix and enact its emission abatement policy. Results also revealed that the low-carbon policy for power plants (e.g., shutting down all coal-fired power plants) could lead to a potentially increment of imported energy for Beijing, which would increase the risk of energy shortage. The findings could help decision makers analyze the interactions between different stakeholders in ESP and provide useful information for policy design under uncertainty. PMID- 29571127 TI - Increase of lifetime cadmium intake dose-dependently increased all cause of mortality in female inhabitants of the cadmium-polluted Jinzu River basin, Toyama, Japan. AB - BACKGROUND: Exposure to cadmium (Cd) via food is supposed to affect life prognosis of inhabitants of Cd-polluted area in Japan. However, there have been few reports demonstrating a significant relationship between the amount of Cd intake and mortality. We aimed to investigate the relationship between mortality and individual lifetime Cd intake (LCd) in inhabitants of the polluted Jinzu River basin, Toyama, Japan. METHODS: We conducted a 26-year follow-up survey in 2407 inhabitants (1208 men and 1199 women) who participated in health examinations for screening of renal dysfunction from 1979 to 1984. The calculation of LCd in each inhabitant was based on the formula of Nogawa (Nogawa et al., 1989): (mean Cd concentration in rice of the present hamlet * 333.5 g/day + 34 MUg/day) * 365 days/year * number of years of residence in the present hamlet + 50 MUg/day * 365 days/year * number of years living in Cd non-polluted regions. In this formula, 333.5 g/day is the 1970 average daily intake of rice in this area, 34 ug/day is the Cd intake from foods other than rice in this area, and 50 MUg/day is the average intake of Cd in non-polluted areas in Japan. Mortality risk ratios of LCd for all and specific causes were estimated after adjustments for age at baseline, smoking status, and history of hypertension using a Cox hazard model or Fine and Gray competing risks regression model. RESULTS: The mortality risk ratios of LCd (+ 1 g) for all causes in women were significantly dose-dependently increased (risk ratio: 1.08). Relative risk of LCd for kidney and urinal tract disease, renal diseases, renal failure and toxic effects of cadmium were significantly higher in women. CONCLUSIONS: The present study documents that individual LCd dose-dependently decreased life prognosis over long-term observation in women. LCd was significantly related to the increased mortality for renal disease and toxic effect of Cd in women. The result provides clear evidence that life prognosis was adversely affected by Cd exposure, especially in women. PMID- 29571128 TI - Impact of informal electronic waste recycling on metal concentrations in soils and dusts. AB - Electronic and electrical equipment contains over 1000 different substances, including metals. During informal e-waste recycling some of these substances such as metals, are released into the environment causing environmental pollution. This study assessed the impact of different informal e-waste recycling activities (burning, dismantling, and repairing) on metal concentrations in top soils and various dust. A comparative cross-sectional study design was adopted to assess metal concentrations in top soils and in various dust samples from multiple e waste recycling sites. Metal concentrations at e-waste recycling sites were compared to the concentrations at control sites in three study locations in Nigeria (Lagos, Ibadan, and Aba). In the three study locations, mean metal concentrations at the e-waste recycling sites exceeded the concentrations at the control sites and the Nigerian standard guideline values by 100 s to 1000 s times. Burning sites showed the highest pollution level, followed by dismantling sites, then repair sites. Our findings show serious environmental and public health concerns. The metal concentrations were also higher than levels reported in other studies at the same locations in Nigeria, indicating that the situation is worsening. This study provides scientific evidence for an urgent need to develop effective strategies to strengthen enforcement of existing e-waste regulations in Nigeria. PMID- 29571125 TI - NADPH oxidases in traumatic brain injury - Promising therapeutic targets? AB - Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Despite intense investigation, no neuroprotective agents for TBI have yet translated to the clinic. Recent efforts have focused on identifying potential therapeutic targets that underlie the secondary TBI pathology that evolves minutes to years following the initial injury. Oxidative stress is a key player in this complex cascade of secondary injury mechanisms and prominently contributes to neurodegeneration and neuroinflammation. NADPH oxidase (NOX) is a family of enzymes whose unique function is to produce reactive oxygen species (ROS). Human post-mortem and animal studies have identified elevated NOX2 and NOX4 levels in the injured brain, suggesting that these two NOXs are involved in the pathogenesis of TBI. In support of this, NOX2 and NOX4 deletion studies have collectively revealed that targeting NOX enzymes can reduce oxidative stress, attenuate neuroinflammation, promote neuronal survival, and improve functional outcomes following TBI. In addition, NOX inhibitor studies have confirmed these findings and demonstrated an extended critical window of efficacious TBI treatment. Finally, the translational potential, caveats, and future directions of the field are highlighted and discussed throughout the review. PMID- 29571129 TI - Dietary transfer of zinc oxide particles from algae (Scenedesmus obliquus) to daphnia (Ceriodaphnia dubia). AB - The rapid increase in production and usage of ZnO particles in recent years has instigated the concerns regarding their plausible effects on the environment. Current study explores the trophic transfer potential of ZnO particles of different sizes (50, 100 nm and bulk particles) from algae (Scenedesmus obliquus) to daphnia (Ceriodaphnia dubia) and the contribution of ZnO(ions) (effect of dissolved Zn ions that remain in test medium after separation NPs) to the overall toxicity of ZnO(total) (impact of both particle and dissolved Zn ions). Toxicity and uptake of ZnO(total) and ZnO(ions) in algae were found to be dependent on the concentration and particle size. Feeding of Zn accumulated algae (517 +/- 28, 354.7 +/- 61 and 291 +/- 20 ug/g dry wt.) post-exposure to 61 uM of ZnO(total) of 50, 100 nm and bulk ZnO particles caused a significant decrease in the survival (15-20%) of daphnia. A significant amount of Zn accumulation was observed in daphnia even after the 48 h depuration period. Biomagnification factor was found to be nearly 1 for all the sizes of ZnO particles tested. For 50 nm ZnO, the BMF was higher when compared to other two sizes, reaching the mean value of 1.06 +/- 0.01 at 61 uM. Further analysis revealed that the dietary uptake of different sizes of ZnO particles caused ultra-structural damages and degradation of internal organs in daphnia. PMID- 29571130 TI - Identification of Ligustici Rhizoma et Radix and its adulterants based on their chemical constituents by UHPLC-Q/TOF-MS combined with data mining. AB - Ligustici Rhizoma et Radix (LR), known as Gaoben (GB) in Chinese, has been used in traditional Chinese medicine for more than 2000 years. However, the varieties of LR are not well characterized at present, and traditional recognition methods have encountered increasing difficulties. This research attempts to distinguish different varieties of LR and its adulterants based on their chemical composition. A total of 61 representative samples were collected, and their varieties were confirmed by combining expert opinion with DNA molecular technology. All of the samples were characterized by an UHPLC-Q/TOF-MS method. The marker components that may contribute to variety discrimination were discerned by a data mining method, and they were then hypothesized, analyzed, and identified. A cluster analysis was performed by partial least squares (PLS) based on their MS signals. Furthermore, a feature extraction to find out the characteristic components, and a correspondence analysis to illustrate the corresponding relationship between the varieties and their components, were developed. As a result, 71 components were identified, of which 27 components were unambiguously identified by comparison with standards. The cluster analysis shows that varieties of LR and its adulterant samples exhibited a certain classification trend, with butylphthalide, senkyunolide I, senkyunolide A, ferulic acid, (Z)-ligustilide, bergapten, levistilide A, vanillic acid, isochlorogenic acid C and isochlorogenic acid A as characteristic chemical components. The varieties and their components showed a modest correlation. In conclusion, our study verified the possibility of discriminating the varieties of LR according to their chemical compositions. This research provides a new reference for the recognition of LR and its adulterants. PMID- 29571131 TI - Nuclear magnetic resonance spectroscopy as a tool for the quantitative analysis of water and ions in pharmaceuticals: Example of heparin. AB - Heparin is a linear, highly sulfated glycosaminoglycan (GAG), which consists of repeating disaccharide units of beta-d-glucuronic acid or alpha-l-iduronic acid and alpha-d-glucosamine. While robust analytical approaches exist for the characterization of organic composition of heparin preparations, there is a lack of methods for the simultaneous quantification of inorganic compounds (water, anions, cations) in this matrix. A nuclear magnetic resonance (NMR) spectrometric method for heparin characterization described in US Pharmacopeia was extended to simultaneous analysis of the inorganic ions (sodium, calcium, and chloride), acetate as well as water content. NMR control of these parameters is possible with only one sample preparation according to the US Pharmacopeia using just four sequential NMR experiments (1H, 2D, 23Na, and 35Cl) with a total measurement time less than 20 min. Validation results in terms of precision, reproducibility, limit of detection and recovery demonstrated that the developed method is fit-for purpose for the authentic heparin samples. The quantitative data for a representative set of more than hundred Na- and Ca- heparin and low-molecular weight heparin (LMWH) samples were discussed regarding animal origin and the type of anticoagulant. NMR spectrometry represents a unique analytical method suitable for the simultaneous quantitative control of organic and inorganic composition of heparin. PMID- 29571132 TI - UGT-mediated metabolism plays a dominant role in the pharmacokinetic behavior and the disposition of morusin in vivo and in vitro. AB - Morusin is a prenylated flavone isolated from mulberry, the branch and root bark of various Morus species, which possesses diverse pharmacological activities. However, it lacks extensive studies about its absorption and disposition. This study investigated the pharmacokinetic behavior of morusin in rat, and its first pass metabolism in situ. The metabolic pathway of morusin was further investigated by 12 human recombinant UDP-glucuronosyltransferases (UGTs), 9 CYP450s, as well as liver and intestinal microsomes. Four mono-glucuronide metabolites (M-5-G, M-4'-G, M-2'-G, and MII-2) were identified in rat intestine and bile by LC-MS/MS, while three of them were also detected in plasma (M-5-G, M 4'-G, and MII-2). M-4'-G was the principal conjugate. However, few CYP450 metabolites were found in rat intestine and bile. Only a small amount of MI-1 could be detected in rat plasma. UGT1A1, 1A3, 1A7, and 2B7 were the major contributors to morusin glucuronidation. Morusin exhibited substrate inhibition kinetic characteristics in all UGTs. Clearance rates of M-4'-G in HLM, RLM, UGT1A1, UGT1A3, and UGT2B7 were 137.02, 127.55, 32.54, 41.18, and 35.07 ml/min/mg, respectively. Besides, CYP3A5, 3A4, and 2C19 primarily contributed to the oxidative metabolism of morusin. The pharmacokinetic curves of morusin and its conjugates presented double peaks, showing that an enterohepatic recycling may exist. In conclusion, glucuronidation was confirmed to be the crucial metabolic pathway for morusin in vivo, and M-4'-G was the main metabolite. PMID- 29571133 TI - LC-MS-based serum fingerprinting reveals significant dysregulation of phospholipids in chronic heart failure. AB - Cardiac and extracardiac lipid metabolism is known to be significantly altered in the course of the heart failure with reduced ejection fraction (HF-REF), however the precise mechanisms are not fully elucidated. The aim of the study was to use of untargeted metabolomics to identify and validate changes in the blood metabolites profile, occurring as a result of HF-REF development. The analyses were performed first in the derivation set (36 chronic HF-REF patients and 19 controls without the disease) and repeated in validation cohort (31 chronic HF REF patients and 20 controls). Independent analyses of both sets revealed statistically significant decline in intensities of phosphatidylcholine (PC): 34:4 and 36:5, lysophosphatidylcholine (lyso-PC): 14:0, 15:0, 18:0, 18:2, 20:3, lysophosphatidylethanolamine (lyso-PE): 18:1 and 18:2 in chronic HF-REF patients. More symptomatic patients and those with ischaemic etiology of HF-REF presented greater deficit in phospholipids (PLs) intensities. The decrease of identified PLs intensities (as compared to controls) correlated with decreased serum cholesterol level, impaired renal function, reduced exercise capacity, enhanced ventilatory response and metabolic parameters associated with altered fatty acids oxidation. In multiple regression analysis PLs deficit was significantly associated with age, carnitines serum intensity, renal function, uric acid, cholesterol level. In conclusion, HF-REF is associated with significant disturbances in phospholipids metabolism. Greater reduction in serum intensities of particular identified PLs is associated with older age, worse clinical condition, impaired oxidative muscle metabolism and enhanced catabolic status. PMID- 29571134 TI - Determination of oroxylin A and oroxylin A 7-O-d-glucuronide in HepG2 cell lysate and subcellular fractions with SPE-UPLC-MS/MS: Cellular pharmacokinetic study to indicate anti-cancer mechanisms. AB - Targeting therapy of anti-cancer drugs has been gaining increasing attention. Cell pharmacokinetics have been used for in vitro disposition evaluation, as well as drug-drug interaction for anti-cancer drugs, revealing their fate after entering tumor. Flavonoid compound oroxylin A (OA) possesses strong anti-cancer effects especially on the liver and breast cancer. However, despite the low bioavailability, the disposition of OA and its active metabolite in the target cancer cells remained unclear. In current study, a highly sensitive and selective solid phase extraction (SPE)-UPLC-MS/MS method was developed and validated to simultaneously quantify the concentrations of OA and its major active metabolite oroxylin A 7-O-d-glucuronide (OG) in HepG2 cell lysate and multiple subcellular organelle fractions. The proposed method appeared to be suitable for the analysis with desirable linearity(R2 > 0.99). The relative standard deviations (RSDs) of intra- and inter-assay precision and accuracy were less than 9.9% and -7.7%, 8.4% and 11% for OA and OG in cell lysate respectively. The intra- precision and accuracy was less than 9.5% and -11.3%, 9.4% and 12.3% for OA and OG in subcellular organelles respectively. The range of absolute recovery of this method in the cell lysate was from 73.1% +/- 1.4% to 87.9% +/- 6.7%. The RSDs of matrix effects of the quality control (QC) samples were below 15%. The uptake and distribution experiments demonstrated a time-dependent transport characteristic in HepG2 cell lines. Furthermore, both OA and OG were mainly distributed into nuclei after taken up by the tumor cells. In addition, OG was also distributed into mitochondria, which indicates another potential target of OG. The present study, for the first time, reports the in vitro cell pharmacokinetics profiles of OA and OG in tumor cell lines in vitro. PMID- 29571135 TI - Simultaneous monitoring of pazopanib and its metabolites by UPLC-MS/MS. AB - Pazopanib is a multi-targeted tyrosine kinase inhibitor (TKI) approved as first line treatment for patients with advanced renal cell carcinoma (RCC) and as second-line treatment for patients with advanced soft tissue sarcoma (STS) previously treated with chemotherapy. The most common adverse events, observed during the RCC and STS trials, were gastrointestinal disorders, hypertension, fatigue, elevated ALAT and ASAT, but the molecular mechanisms explaining pazopanib toxicity remain unclear. Therapeutic activity is considered to be mainly dependent on pazopanib exposure as the primary metabolites are inactive or display low plasma concentrations, but metabolites may be involved in toxicity as relationships between metabolite profiles and toxicity have not been evaluated. We report here, for the first time, the validation of a method for the simultaneous quantification of pazopanib and semi-quantification of its metabolites (relative determination). As there are no standards available, pazopanib metabolites were generated with human liver microsomes (HLM) to provide controls in the development of an UPLC-MS/MS method for monitoring both pazopanib and metabolites. The optimised method was validated for specificity, linearity, sensitivity, precision, accuracy, matrix effect and stability. The coefficient of variation (CV%) for intra-day and inter-day precision varied from 2.1% to 7.9% and 5.6% to 13.1% respectively. The biases varied from -12% to 2.3% (intra-day) and 3.8% to 13.1% (inter-day) for accuracy evaluation. Intra-day and inter-day precision CV were respectively 20.1% and 19.6% and accuracy biases were between 20.7% (intra-day) and 3.8% (inter-day) at the limit of quantification. The recoveries from matrix samples spiked with pazopanib were respectively 102.6 +/- 12.9% and 102.5 +/- 1.2% at low and high levels of calibration range. No matrix effect was evidenced as demonstrated by the normalised matrix factor values: 1.3 +/- 0.1 and 1.2 +/- 0.2 respectively measured at low and high part of calibration range. A good stability of pazopanib was observed during short term, long term and in process storage conditions and after three freeze/thaw cycles. The method was applied to clinical samples from three patients treated with pazopanib to establish the metabolite profiles (semi-quantitative data) during treatment. The assessment of metabolite profiles could be useful to improve our understanding of the occurrence of adverse events and to improve pazopanib pharmacokinetic pharmacodynamic relationships. PMID- 29571136 TI - In line monitoring of the powder flow behavior and drug content in a Fette 3090 feed frame at different operating conditions using Near Infrared spectroscopy. AB - Near infrared (NIR) spectroscopy was used to determine the drug concentration in 3% (w/w) acetaminophen blends within the complex flow regime of the tablet press feed frame just before tablet compaction. NIR spectra also provided valuable information on the powder flow behavior within the feed frame and were used to track when a process enters or leaves the steady state. A partial least squares regression calibration model was developed with powder mixtures that varied from 1.5 to 4.5% (w/w) by obtaining 135 spectra after steady state for each concentration while the feed frame and die disc operated at 30.5 revolutions per minute (rpm). The calibration model determined drug concentration in validation blends with a root mean square error of prediction and bias below 0.1% (w/w). The robustness of the NIR calibration model was evaluated by determining the effect of variation on the operating conditions (paddle wheel speed and die disc speed) on NIR predictions. This work found that the paddle wheel speed can be increased up to 30% and the die disc speed decrease 10% without affecting NIR predictions. The results demonstrated that paddle wheel speed has a significant effect on the wave powder behavior (frequency and amplitude) but does not have significant effect on the mass hold-up within feed frame. The die disc speed does not affect wave powder behavior but affects significantly the mass hold-up inside the feed frame. This information can be used to reduce the tablet weight variability and ensure that this critical attribute is met. PMID- 29571137 TI - Efficient nano titanium electrode via a two-step electrochemical anodization with reconstructed nanotubes: Electrochemical activity and stability. AB - A two-step anodization method was used to prepare an efficient nano Ti electrode (ENTE), based on the nano Ti electrode (NTE) that was synthesized by the traditional anodization method. The result of FESEM showed there were many nanopores and nanoparticles on the surface of the ENTE. Compared with Ti electrode, the ENTE exhibited an increased electrochemical activity of nitrate reduction, attributing to its ~1.09-fold higher reduction peak current density. Values of average current efficiency towards nitrate reduction indicated that the electrochemical properties of different electrodes were raised in the order of ENTE (0.36) > NTE (0.25) > Ti electrode (0.15). The ENTE exhibited a ~3.33-fold higher electroactive surface area than that of Ti electrode. The higher current density throughout the 1000 s and the ~1.27-fold higher final current density at 1000 s suggested that the ENTE had a higher stability for nitrate electroreduction. The nitrate reduction efficiency increased with the increasing of initial nitrate-nitrogen concentration and temperature. Similar effect was obtained from current density below 50 mA cm-2. And under the neutral condition, a higher nitrate reduction efficiency was achieved. The curved surface and higher surface area due to the nanopores of the ENTE increased the nitrate concentration in the EDL and enhanced the potential of individual nitrate ions in the diffuse layer exponentially. This research provided a new route to assess a nano electrode with high stability and a clear reaction mechanism in EDL. PMID- 29571138 TI - Mitigation of harmful indoor organic vapors using plug-flow unit coated with 2D g C3N4 and metallic Cu dual-incorporated 1D titania heterostructure. AB - Herein, a plug-flow reactor coated with one-dimensional (1D) TiO2 nanotube (TNT) heterostructures incorporated with g-C3N4 (CN) and metallic Cu (CN/Cu/TNT) nanocomposite and irradiated by a daylight lamp was newly applied for the mitigation of harmful indoor organic vapors. The CN/Cu/TNT catalyst showed high mitigation efficiency for all target pollutants, followed by Cu-incorporated TNT (Cu/TNT), CN-incorporated TNT (CN/TNT), TNT, and TiO2, in that order. The order of their photocatalytic activities agrees with that of the electron-hole separation rates determined from their photoluminescence emission spectra. The mitigation efficiency of the CN/Cu/TNT catalyst increased as the CN-to-Cu/TNT percentage was increased from 1% to 10%, but subsequently decreased as the CN-to Cu/TNT percentage increased to 20%. The mitigation efficiencies of the CN/Cu/TNT catalyst decreased with increasing relative humidity, feed pollutant concentrations, and airstream flow rates. However, in most cases, the reaction rates of the target compounds increased when the feed concentration was increased from 1 to 5 ppm. The mineralization rates of all target pollutants were lower than the corresponding photocatalytic mitigation rates, which could be ascribed to the production of CO and organic intermediates observed during the photocatalysis of the target pollutants. Nevertheless, the intermediates formed during the photocatalytic mitigation process would not cause significant adverse health effects to building occupants, because their concentrations were far below their exposure or threshold limit values. A probable mechanism for the photocatalytic mitigation of the organic vapors by the CN/Cu/TNT catalyst under daylight illumination was also proposed.

AB - The membrane concentrate from landfill leachate has great potential risks of the environmental pollution. The aim of this study was to investigate the structure effect of stacked electro-Fenton (EF) reactor on the nanofiltration (NF) concentrate treatment from landfill leachate. The stacked EF reactor was constructed with a carbon-PTFE gas diffusion cathode and an IrO2-Ta2O5 anode with different electrode spacings (i.e., 2, 5, 10, and 40 mm) and electrode pairs (i.e., 1, 3, 6, and 9). Results showed that smaller electrode spacing and more electrode pairs in the stacked EF reactor improved the COD removal in the NF concentrate treatment. The specific energy consumption decreased with smaller electrode spacing but increased with more electrode pairs. Under the current density of 15 mA cm-2, Fe2+ dosage of 560 mg L-1, the stacked EF reactor with 9 electrode pairs and the electrode spacing of 2 mm removed 71 +/- 6% of the total COD in the NF concentrate within 6 h and the specific energy consumption was 207 +/- 20 kWh?kg COD-1. The COD removal was kept stable in the stacked EF reactor within 3 cycles of operation. Three-dimensional fluorescence spectroscopic and gas chromatographic mass spectrometric analysis showed that humic acids and aromatic proteins were efficiently degraded in the EF process and large amount of aromatic hydrocarbons was detected in the treated NF concentrate. Our stacked EF reactor could be used to treat leachate concentrates with effectively degradation of the refractory organic pollutants.

AB - In the present study novel polypyrrole-cellulose-graphene oxide nanocomposite (PCeGONC) was employed for the immobilization of ginger peroxidase (GP) via simple adsorption mechanism. Immobilization of enzyme on the obtained support resulted in enhancement of the enzyme activity. The recovery of activity was 128% of the initial activity. Consequently, in 3 h stirred batch treatment, PCeGONC bound GP exhibited higher decolorization efficiency (99%) for Reactive Blue 4 (RB 4) dye as compared to free GP (88%). The immobilized GP exhibited higher operational stability and retained approximately 72% of its initial activity even after ten sequential cycles of dye decolorization in batch process. The kinetic characterization of PCeGONC bound GP revealed slightly lower Km and 3.3 times higher Vmax compared to free GP. Degraded products were identified on the basis of GC-MS analysis and degradation pathway was proposed accordingly which confirms enzymatic breakdown of RB 4 into low molecular weight compounds. Genotoxic assessment of GP treated RB 4 revealed significant reduction of its genotoxic potential. In-silico analysis identified that binding site of PCeGONC on enzyme is distinct and lies far away from the active site of the enzyme. Furthermore, it also revealed higher affinity of 1-hydroxybenzotriazole (a redox mediator) and RB 4 for PCeGONC bound enzyme as compared to the free enzyme. This is in consensus with the observed decrease in Km of the immobilized GP.

AB - This research investigates the toxic organic compounds biodegradation efficiency of two-stage activated sludge systems with (bioaugmented) and without aged sludge bioaugmentation (non-bioaugmented). The influent was a mixture of leachate and agriculture wastewater (1:1, v/v), used as the representative high strength wastewater. The bioaugmented and non-bioaugmented systems were operated in parallel, with three levels (low, moderate, and high) of concentrations of organics, nitrogen, and toxic organic compounds in the influent (conditions 1, 2, and 3). The results showed that both systems could efficiently degrade the organic compounds. Nevertheless, the toxic organic compounds biodegradation efficiency of the bioaugmented system was higher than that of the non bioaugmented one. The bioaugmentation enhanced the overall removal efficiency under conditions 1 and 2. However, the bioaugmented system became less effective under condition 3. Further analysis indicated that the bacterial groups essential to the toxic organic compounds biodegradation were abundant in the aged sludge, including heterotrophic bacteria, heterotrophic nitrifying bacteria, and nitrifying bacteria. The abundance of the effective bacteria improved the biodegradation and wastewater treatment performance of the bioaugmented system. In essence, the aged sludge bioaugmentation is a viable and eco-friendly solution to improving the treatment efficiency of the biological activated sludge system, despite limited biodegradation efficiency in an elevated compounds-concentration environment.

AB - A physiologically-based pharmacokinetic (PBPK) model for perfluorinated alkyl acids (PFAAs) in rainbow trout has been updated to include formation of perfluorooctanoic acid (PFOA) from the biotransformation of 8:2 fluorotelomer carboxylic acid (8:2 FTCA). The updated model is dynamic and simulates both uptake and depuration phases. Two empirical studies are used to parameterize and test the model. In the first case, parameters related to fecal elimination and protein binding were optimized. In the second case, parameters were sourced either from literature or from optimized values based on the first study to test model performance. Optimization of parameters resulted in a decrease in the difference between experimental data and simulation results by 57 and 23 percent for the first and the second case, respectively, compared to the original case. Sensitivity analysis was performed to identify important parameters, and uncertainty in model prediction propagated by these parameters was assessed using Monte Carlo analysis. For each case, 80 and 89 percent, respectively, of median predicted values were within the limits of experimental error when comparing simulated and experimental data. This is the first toxicokinetic model that incorporates biotransformation of PFAA precursors and simultaneously predicts the distribution of the precursor and metabolite in different tissues. The model is mechanistic, and could be applied to simulate a variety of scenarios by using the organism-specific physiological properties compiled here with other chemical specific parameters (e.g. protein interactions). PMID- 29571143 TI - Use of ozone-biofiltration for bulk organic removal and disinfection byproduct mitigation in potable reuse applications. AB - The purpose of this research was to investigate the impacts of ozone dose and empty bed contact time (EBCT) in ozone-biofiltration systems on disinfection byproduct (DBP) formation potential. The data were used to evaluate the possibility of using DBP formation potential as an alternative guideline for total organic carbon (TOC) removal in potable reuse applications. A pilot-scale ozone-biofiltration system was operated with O3/TOC ratios ranging from 0.1 to 2.25 and EBCTs ranging from 2 to 20 min. The biofiltration columns contained anthracite or biological activated carbon (BAC). Bench-scale chlorination was performed using the uniform formation conditions (UFC) approach, and quenched samples were analyzed for total trihalomethanes (TTHMs) and regulated haloacetic acids (HAA5s). The data demonstrated that ozone-biofiltration achieved TOC removals ranging from ~10 to 30%, depending on operational conditions, but biofiltration without ozone generally achieved <10% TOC removal. UFC testing demonstrated that ozone alone was efficient in transforming bulk organic matter and reducing DBP formation potential by 10-30%. The synergistic combination of ozone and biofiltration achieved average overall reductions in TTHM and HAA5 formation potential of 26% and 51%, respectively. Finally, a maximum TOC concentration of 2.0 mg/L was identified as a recommended treatment target for reliable compliance with TTHM and HAA5 regulations for potable reuse systems in the United States. PMID- 29571144 TI - Sequential application of Fenton and ozone-based oxidation process for the abatement of Ni-EDTA containing nickel plating effluents. AB - Treatment of Ni-EDTA in industrial nickel plating effluents was investigated by integrated application of Fenton and ozone-based oxidation processes. Determination of integrated sequence found that Fenton oxidation presented higher apparent kinetic rate constant of Ni-EDTA oxidation and capacity for contamination load than ozone-based oxidation process, the latter, however, was favorable to guarantee the further mineralization of organic substances, especially at a low concentration. Serial-connection mode of two oxidation processes was appraised, Fenton effluent after treated by hydroxide precipitation and filtration negatively affected the overall performance of the sequential system, as evidenced by the removal efficiencies of Ni2+ and TOC dropping from 99.8% to 98.7%, and from 74.8% to 66.6%, respectively. As a comparison, O3/Fe2+ oxidation process was proved to be more effective than other processes (e.g. O3 Fe2+, O3/H2O2/Fe2+, O3/H2O2-Fe2+), and the final effluent Ni2+ concentration could satisfied the discharge standard (<0.1 mg L-1, China) under the optimal conditions (H2O2 dosage of 1.0 mL L-1, Fe2+: H2O2 mole ratio of 1.46, and reaction time of 10 min for Fenton reaction, initial influent pH of 3.0, O3 dosage of 252 mg L-1, Fe2+ of 150 mg L-1, and reaction time of 30 min for O3/Fe2+ oxidation). Furthermore, pilot-scale test was carried out to study the practical treatability towards the real nickel plating effluent, revealing the effective removal of some other co-existence contaminations. And Fenton reaction has contributed most, with the percentage ranging from 72.41% to 93.76%. The economic cost advantage made it a promising alternative to the continuous Fenton oxidation. PMID- 29571145 TI - Atmospheric concentrations and gas-particle partitioning of PCDD/Fs and dioxin like PCBs around Hochiminh city. AB - Atmospheric PCDD/Fs and dl-PCBs samples were collected in Hochiminh city, Vietnam to address the effect of meteorological parameters, especially rainfall, on the occurrence and gas/particle partitioning of these persistent organic pollutants. The results indicate that PCDD/Fs and dl-PCBs concentrations in industrial site are higher than those measured in commercial and rural sites during both rainy and dry seasons. In terms of mass concentration, ambient PCDD/F levels measured in dry season are significantly higher than those measured in rainy season while dl-PCB levels do not vary significantly between rainy and dry seasons. The difference could be attributed to different gas/particle partitioning characteristics between PCDD/Fs and dl-PCBs. PCDD/Fs are found to be mainly distributed in particle phase while dl- PCBs are predominantly distributed in gas phase in both rainy and dry seasons. Additionally, Junge-Pankow and Harner Bidleman models are applied to better understand the gas/particle partitioning of these pollutants in atmosphere. As a results, both PCDD/Fs and dl-PCBs are under non-equilibrium gas/particle partitioning condition, and PCDD/Fs tend to reach equilibrium easier in rainy season while there are no clear trend for dl-PCBs. Harner-Bidleman model performs better in evaluating the gas/particle partitioning of PCDD/Fs while Junge-Pankow model results in better prediction for dl-PCBs. PMID- 29571146 TI - Occurrence and partitioning behavior of organophosphate esters in surface water and sediment of a shallow Chinese freshwater lake (Taihu Lake): Implication for eco-toxicity risk. AB - Organophosphate esters (OPEs) are ubiquitous in the aquatic environment, which have been considered or suspected as carcinogens and neurotoxicants. In this study, the occurrence, spatial distribution, potential sources, partitioning character and potential risks of OPEs in the surface water and sediment collected from Taihu Lake were investigated. The concentrations of ?12 OPEs varied from 1.0 * 102 to 1.7 * 103 ng/L for the surface water and from 8.1 to 4.2 * 102 ng/g dw for the sediment. Trimethyl phosphate (TEP) was the predominant congener in the surface water, while Tris(2-ethylhexyl) phosphate (TEHP) in the sediment. Positive correlations between OPEs indicated that they may have the same sources and/or similar environmental behavior. The pseudo-partitioning values of OPEs ranged from 0.59 to 6.5 * 104 L/kg. TEHP has the highest pseudo-partitioning coefficient, which indicated that TEHP inclined to be enriched in the sediment in Taihu Lake. Risk assessment (RQ) showed that individual OPEs in the surface water and sediment posed no/low risk to aquatic organisms, except 2-Ethylhexyl diphenyl phosphate (EHDPP) (moderate risk) in water. PMID- 29571147 TI - Counteranion-dependent sorption of imidazolium- and benzimidazolium-based ionic liquids by soot. AB - Sorption of ionic liquids (ILs) to soil and porous materials as affected by anions was observed, but scarce effort has been focused on addressing the role of counteranions in sorption and the associated underlying mechanisms. In this work, two series of 1-butyl-3-methylimidazolium- (Bmim-) and N-butyl, methyl benzimidazolium-based (Bmbim-based) ILs coupled with different counteranions were prepared to investigate the effect of anions on IL sorption by soot. The octanol water partition coefficient (Kow) and the ion-pair formation constant at infinite dilution in water (KIP degrees ) of ILs were independently measured to explore the contribution of counteranion-dependent hydrophobicity and ion-pair. A wide range of sorption coefficients (Kd) of ILs were achieved with values varying from 59.8 to 344.3 L.kg-1 for Bmbim-based ILs and from 253.4 to 489.7 L kg-1 for Bmbim based ILs. Compared with other anions, bis(trifluoromethanesulphonyl)imide ([Tf2N]-) and hexafluorophosphate ([PF6]-) exhibit tighter association with IL cations in aqueous solution due to their larger Kow and higher KIP degrees . Positive linear relationships between log KIP degrees and Kd and between log Kow and Kd evidenced that the counteranion-dependent sorption of ILs relies on the association strengths of IL cations and counteranions, which further influence the hydrophobicity/hydrophilicity of ion pairs. Compared with that of strongly coordinating anions (such as [CH3SO3]-, [CF3COO]-, [BF4]-, [CF3SO3]-, and [Cl]-), the addition of weakly coordinating anions (such as [Tf2N]- and [PF6]-) in solution contributes to markedly large sorption enhancement of ILs. Consequently, the contribution of different counteranions on IL sorption is essentially based on the formation of ion pair with different KIP degrees and Kow in aqueous solution. PMID- 29571148 TI - Microbial vanadium (V) reduction in groundwater with different soils from vanadium ore mining areas. AB - This work investigated the potential of vanadium (V) (V(V)) bioreduction by using soils sampled from four main kinds of vanadium ore mining areas, i.e. vanadium titanomagnetite, stone coal, petroleum associated minerals and uvanite as inocula. During a typical operation cycle of 60 h, the soils from vanadium titanomagnetite area and petroleum associated minerals area exhibited higher V(V) removal efficiencies, about 92.0 +/- 2.0% and 91.0 +/- 1.9% in comparison to 87.1 +/- 1.9% and 69.0 +/- 1.1% for the soils from uvanite and stone coal areas, respectively. Results from high-throughput 16 S rRNA gene pyrosequencing analysis reflect the accumulation of Bryobacter and Acidobacteriaceae with capabilities of V(V) reduction, accompanied with other functional species. This study is helpful to search new functional species for V(V) reduction and to develop in situ bioremediations of V(V) polluted groundwater. PMID- 29571149 TI - Alkaloids from Corydalis decumbens suppress neuronal excitability in primary cultures of mouse neocortical neurons. AB - Eight previously undescribed alkaloids, named corydemine, dihydrocorydemine, corydedine, 8,13-dioxo-14-hydroxytetrahydropalmatine, egenine-alpha-N-oxide, egenine-beta-N-oxide, 7'-O-ethylegenine-alpha-N-oxide, and 7'-O-ethylegenine-beta N-oxide, together with three known ones, muramine, l-tetrahydropalmatine, and (+) egenine, were isolated from the bulbs of Corydalis decumbens. Their structures were elucidated by comprehensive spectroscopic analysis and chemical correlation. The isolated compounds were tested for their ability to modulate neuronal excitability in primary cultured neocortical neurons. Four of the compounds, corydemine, dihydrocorydemine, muramine, and l-tetrahydropalmatine, inhibited neuronal excitability with IC50 values of 3.6, 16.7, 13.5 and 14.0 MUM, respectively. PMID- 29571150 TI - Metabolomic analysis applied to chemosystematics and evolution of megadiverse Brazilian Vernonieae (Asteraceae). AB - Vernonia sensu lato is the largest and most complex genus of the tribe Vernonieae (Asteraceae). The tribe is chemically characterized by the presence of sesquiterpene lactones and flavonoids. Over the years, several taxonomic classifications have been proposed for Vernonia s.l. and for the tribe; however, there has been no consensus among the researches. According to traditional classification, Vernonia s.l. comprises more than 1000 species divided into sections, subsections and series (sensu Bentham). In a more recent classification, these species have been segregated into other genera and some subtribes were proposed, while the genus Vernonia sensu stricto was restricted to 22 species distributed mainly in North America (sensu Robinson). In this study, species from the subtribes Vernoniinae, Lepidaploinae and Rolandrinae were analyzed by UHPLC-UV-HRMS followed by multivariate statistical analysis. Data mining was performed using unsupervised (HCA and PCA) and supervised methods (OPLS-DA). The HCA showed the segregation of the species into four main groups. Comparing the HCA with taxonomical classifications of Vernonieae, we observed that the groups of the dendogram, based on metabolic profiling, were in accordance with the generic classification proposed by Robinson and with previous phylogenetic studies. The species of the genera Stenocephalum, Stilpnopappus, Strophopappus and Rolandra (Group 1) were revealed to be more related to the species of the genus Vernonanthura (Group 2), while the genera Cyrtocymura, Chrysolaena and Echinocoryne (Group 3) were chemically more similar to the genera Lessingianthus and Lepidaploa (Group 4). These findings indicated that the subtribes Vernoniinae and Lepidaploinae are non-chemically homogeneous groups and highlighted the application of untargeted metabolomic tools for taxonomy and as indicators of species evolution. Discriminant compounds for the groups obtained by OPLS-DA were determined. Groups 1 and 2 were characterized by the presence of 3',4'-dimethoxyluteolin, glaucolide A and 8-tigloyloxyglaucolide A. The species of Groups 3 and 4 were characterized by the presence of putative acacetin 7-O rutinoside and glaucolide B. Therefore, untargeted metabolomic approach combined with multivariate statistical analysis, as proposed herein, allowed the identification of potential chemotaxonomic markers, helping in the taxonomic classifications. PMID- 29571151 TI - Folate homeostasis in epileptic rats. AB - Folate is involved in metabolic processes and it has been implicated in both aggravation and amelioration of seizures. The aim of the current work was to study the effect of chronic temporal lobe epilepsy (TLE) on the plasma and brain concentrations of folate and on its uptake carriers in the brain - the reduced folate carrier (RFC), folate receptor alpha (FRalpha) and proton coupled folate transporter (PCFT). We utilized the rat lithium pilocarpine model for TLE. Approximately two months following status epilepticus, rats with spontaneous recurrent seizures (SRS) were sacrificed for brain and plasma folate concentration analyses and folate uptake carrier expression studies. RT-PCR and western blot analyses were utilized for quantification of folate carriers' mRNAs and proteins, respectively. The distribution of folate carriers in the brain was studied using immunohistochemistry. In the SRS rats we found lower plasma concentrations (10 +/- 0.9 in control vs. 6.6 +/- 1.6 ng/ml in SRS, P < 0.05), but preserved cortical and increased hippocampal levels of folate (0.5 +/- 0.1 in control vs. 0.9 +/- 0.2 ng/mg in SRS, P = 0.055). Hippocampus - to - plasma ratio of folate concentration was 3-fold higher in the SRS group, compared with the controls (0.13 +/- 0.03 vs. 0.04 +/- 0.02, respectively; P < 0.01). mRNA and protein levels of the folate uptake carriers did not differ between SRS rats and controls. However, immunofluorescent staining quantification revealed that the emission intensity of both RFC and FRalpha was elevated 8-fold and 4-fold, respectively, in hippocampal CA1 neurons of SRS rats, compared to controls (P < 0.01). PCFT was unquantifiable. If corroborated by complementary research in humans, the findings of this study may be utilized clinically for supplemental therapy planning, in imaging the epileptic focus, and for drug delivery into the epileptic brain. Further studies are required for better elucidating the clinical and mechanistic significance of altered folate balances in the epileptic brain. PMID- 29571152 TI - Comparative efficacy of unique antiepileptic drug regimens in focal epilepsy: An exploratory study. AB - OBJECTIVE: To compare efficacy of unique antiepileptic drug (AED) polytherapy regimens among patients with focal epilepsy. METHODS: From a longitudinal study of AED treatment, we identified patients with active focal epilepsy who had attempted at least two unique AED regimens (mono-, duo-, or tri-therapy). Efficacy was defined as the presence of at least one six-month period of continuous seizure freedom during exposure to a regimen. To control for individual variations in response and epilepsy severity, we used within-patient comparison approaches, in which we: 1) compared head-to-head unique regimens tried within the same patients; 2) compared one regimen versus aggregate of other regimens attempted in that patient; and 3) compared aggregated monotherapy versus polytherapy regimens. RESULTS: 757 patients met our criteria and had collectively attempted 170 unique regimens. In the head-to-head analysis, lamotrigine monotherapy was more effective than phenytoin monotherapy. Two regimens were more effective than the aggregate of other regimens attempted: levetiracetam/lamotrigine duotherapy and lamotrigine monotherapy. Two other regimens exhibited slightly better efficacy but did not reach statistical significance: clobazam/levetiracetam/lamotrigine and levetriacetam/oxcarbazepine. Patients who previously attempted at least four regimens had slightly better outcomes on polytherapy than monotherapy, though this was not significant. SIGNIFICANCE: We identified two unique regimens more likely to be associated with >=6 months of seizure freedom: levetiracetam/lamotrigine duotherapy and lamotrigine monotherapy. Polytherapy may be an effective alternative to monotherapy for patients with focal epilepsy and persistent seizures. PMID- 29571153 TI - Tangential cranial ballistic impact: An illustration of the limitations of post mortem CT scan? AB - Post-mortem imaging has become more frequently used in forensic procedures, notably in a ballistic context. Despite many advances in this field, the interpretation of computed tomography (CT) can be a very complex matter. Our case illustrates the difficulties of interpretation after quasi-tangential cranial ballistic impact and keyhole wounds. These wounds are difficult to visualize on CT and are among the factors complicating the precise determination of ballistics. These sources of error remind us that CT findings must be interpreted in close comparison with autopsy findings. PMID- 29571154 TI - Postmortem interval estimation using the animal model of postmortem gas volume changes. AB - It is important to estimate the postmortem interval in forensic autopsy. Many methods to estimate the postmortem interval have been reported, and are typically associated with internal examination. However, there are issues such as rejection of autopsy by the family and a lack of forensic doctor in internal examination. Therefore, it is necessary to develop new methods, such as autopsy imaging, that can substitute for internal examination. Here, we first evaluated whether gas volume in the body increased with postmortem interval. Time-dependent X-ray CT imaging of euthanized Crl:CD (SD) rats (n = 3) was performed immediately after euthanasia and at seven subsequent time points up to 168 h (7 days) at 24-hour intervals. The data revealed that gas volume in the body increased in a time dependent manner. Next, we reconstructed 3D images of isolated gas and calculated the gas volume using Amira software. In all cases, the volume of both portal venous gas and intestinal gas increased in a time-dependent manner. The volume of portal venous gas increased exponentially, while the volume of intestinal gas increased in a linearly with time. These data might be suggested that the postmortem gas volume change is one of indicators for estimating the postmortem interval. In addition, it would be possible to estimate more accurate postmortem interval by combining not only gas volume changes at the above two sites but also gas volume changes of the other sites such as heart cavities, kidney parenchyma, or abdominal aorta.

AB - The design, synthesis and biological evaluation of a library of 1,2,3-triazole carboxylates incorporating carboxylic acid, hydroxymethyl, carboxylic acid hydrazide, carboxamide and benzenesulfonamide moieties is disclosed. All the novel compounds were investigated for their inhibition potential against carbonic anhydrase (CA, EC 4.2.1.1) human (h) isoforms hCA I, II, IV and IX, well established drug targets. The cytosolic isoform hCA I was inhibited with Ki's ranging between 53.2 nM and 7.616 MUM whereas the glaucoma associated cytosolic isoform hCA II was inhibited with Ki's in the range 21.8 nM-0.807 MUM. The membrane bound isoform hCA IV, involved in glaucoma and retinitis pigmentosa among others, was effectively inhibited by some of these compounds with Ki < 60 nM, better than the reference drug acetazolamide (AAZ). The tumor associated isoform hCA IX, a recently validated antitumor/antimetastatic drug target, was also effectively inhibited by some of the new sulfonamides, which possess thus the potential to be used as tools for exploring in more details the selective inhibition of hCAs involved in various pathologies. PMID- 29571156 TI - Simple 2(5H)-furanone derivatives with selective cytotoxicity towards non-small cell lung cancer cell line A549 - Synthesis, structure-activity relationship and biological evaluation. AB - A series of 5-alkoxy derivatives of 3,4-dichloro-5-hydroxyfuran-2-(5H)-one (mucochloric acid, MCA) were obtained and subsequently subjected to modification in the C-4 position of 2(5H)-furanone ring. The cytotoxicity of newly synthesized compounds was evaluated in MTT assay against non-small cell lung cancer (A549) and healthy lung epithelial cell line (BEAS-2B). The derivatives containing a branched alkoxy substituent in the C-5 position demonstrated the highest anticancer properties, whereas modification of compounds in the C-4 position of 2(5H)-furanone ring only slightly improve their antiproliferative properties. Compounds 12 and 15 exhibited the best selectivity towards A549 cells and were also evaluated in a panel of cancer cell lines of different origin. Further investigation revealed that treatment of A549 cell line with compounds 12 and 15 led to G2 phase cell cycle arrest and induction of caspase-independent cell death. Moreover, compound 12 was found to act synergistically with erlotinib. PMID- 29571158 TI - Molecular features of nonionic detergents involved in the binding kinetics and solubilization efficiency, as studied in model (Langmuir films) and biological (Erythrocytes) membranes. AB - The effect of the nonionic detergents Brij-98 and Brij-58 over human erythrocytes was studied through quantitative hemolysis and in Langmuir films. Hemolytic tests revealed that Brijs are stronger membrane solubilizers than Triton X-100 (TX 100), with effective detergent/lipid ratios of 0.18 and 0.37 for Brij-98 and Brij 58, respectively. Experiments with Langmuir films provided significant information on the kinetics and thermodynamics of detergent-membrane interaction. The adsorption (ka) and desorption (kd) rate constants of Brijs were lower than those of TX-100. In the case of ka, that is probably due to their larger hydrophilic head (with twice (20) the oxyethylene units of TX-100). As for the thermodynamic binding constant, the linear and longer hydrophobic acyl chains of Brijs favor their stabilization in-between the lipids, through London van der Waals forces. Consequently, Kb,m values of Brij-98 (12,500 M-1) and Brij-58 (19,300 M-1) resulted higher than TX-100 (7500 M-1), in agreement with results from the hemolytic tests. Furthermore, Brij-58 binds with higher affinity than Brij-98 to bilayers and monolayers, despite its shorter (palmitic) hydrocarbon chain, showing that unsaturation restrains the detergent insertion into these environments. Our results provide significant information about the mechanism of interaction between Brijs and membranes, supporting their distinct solubilization effect. PMID- 29571159 TI - Selenium nanocomposites as multifunctional nanoplatform for imaging guiding synergistic chemo-photothermal therapy. AB - A multifunctional selenium nanocomposite (selenium@silica core-shell nanoshperes for loading indocyanine green(ICG)/Doxorubicin(DOX)) was fabricated to reach visible and efficient cancer treatment. The Se@SiO2-ICG nanocomposites could be used not only as excellent photothermal agents but also as carriers for DOX delivery. In addition, the Se@SiO2-ICG/DOX nanocomposites exhibited excellent fluorescence imaging and infrared imaging performance. Tumor could be effectively inhibited by Se@SiO2-ICG/DOX due to the triple treatment of photothermal effect and chemotherapy of selenium and DOX. Thus, the Se@SiO2-ICG/DOX nanocomposites have a great potential in imaging guiding synergistic treatment of cancer. PMID- 29571157 TI - Antimalarial agents against both sexual and asexual parasites stages: structure activity relationships and biological studies of the Malaria Box compound 1-[5-(4 bromo-2-chlorophenyl)furan-2-yl]-N-[(piperidin-4-yl)methyl]methanamine (MMV019918) and analogues. AB - Therapies addressing multiple stages of Plasmodium falciparum life cycle are highly desirable for implementing malaria elimination strategies. MMV019918 (1, 1 [5-(4-bromo-2-chlorophenyl)furan-2-yl]-N-[(piperidin-4-yl)methyl]methanamine) was selected from the MMV Malaria Box for its dual activity against both asexual stages and gametocytes. In-depth structure-activity relationship studies and cytotoxicity evaluation led to the selection of 25 for further biological investigation. The potential transmission blocking activity of 25 versus P. falciparum was confirmed through the standard membrane-feeding assay. Both 1 and 25 significantly prolonged atrioventricular conduction time in Langendorff isolated rat hearts, and showed inhibitory activity of Ba2+ current through Cav1.2 channels. An in silico target-fishing study suggested the enzyme phosphoethanolamine methyltransferase (PfPMT) as a potential target. However, compound activity against PfPMT did not track with the antiplasmodial activity, suggesting the latter activity relies on a different molecular target. Nevertheless, 25 showed interesting activity against PfPMT, which could be an important starting point for the identification of more potent inhibitors active against both sexual and asexual stages of the parasite. PMID- 29571160 TI - One-step selective screening of bioactive molecules in living cells using sulfur doped microporous carbon. AB - A metal-free electrode using heteroatom-doped microporous carbon was fabricated for the ultrasensitive monitoring of mono-bioactive molecules and the selective signaling of dopamine (DA) secreted by living cells. The constructed electrode based on sulfur-doped microporous carbon (S-MC) shows a high surface area, a spherical construction, numerous carbon chain defects, and microporous structures, which are the key factors of the interactive signaling transducer, fast response, and active interfacial surfaces. The intrinsic features of S-MC with different %S-doping (S-MC-1, and S-MC-2) through the sp2-carbon chain create abundant catalytic active sites, facilitate molecular diffusion through the microporous structure, promote strong binding with the targeted molecules, and induce interactions at electrolyte-electrode interfaces. The S-MC-1 provides selective signaling in a tertiary mixture of DA, ascorbic acid (AA), and uric acid (UA) with a high sensitivity and a wide linear range of 0.01-5, 10-4000, and 1-2000 uM, respectively. The detection limits were set at 3 nM, 1.26 uM, and 0.23 uM for DA, AA, and UA respectively. The S-MC-1 demonstrated a selective screening of DA released from PC12 cells under a K+ ion- stimulator with high sensitivity and promoted high biocompatibility, low cytotoxicity, high stability, and reliable reproducibility (%RSD ranged from 1 to 2.7). Our findings indicated that the S-MC-1 can be utilized as an in-vitro model for simultaneously monitoring extracellular-DA secreted from living cells and sensing mono-bioactive molecules in biological samples.

AB - In this work, electrically-conducting poly(Toludine Blue) was employed for the first time as synthetic receptor film, prepared by Molecular Imprinting strategies and using electrochemical methods, for the specific screening of breast cancer biomarker Carbohydrate Antigen 15-3 (CA 15-3). The protein imprinted poly(Toluidine Blue) film was grown in a pre-formed Toluidine Blue (TB) tailed SAM at the AuSPE surface, which greatly enhanced the stability against degradation of the Molecular Imprinted Polymer (MIP) film at the electrode surface. The MIP receptor film recognition ability towards the protein was investigated by fitting data to Freundlich isotherm. The binding affinity (KF) obtained for the MIP system was significantly higher (~ 12-fold) to that obtained for the NIP system, demonstrating the success of the approach in creating imprinted materials that specifically respond to CA 15-3 protein. The incubation of the MIP modified electrode with increasing concentration of protein (from 0.10 U mL-1 to 1000 U mL-1) resulted in a decrease of the ferro/ferricyanide redox current. The device displayed linear response from 0.10 U mL-1 to 100 U mL-1 and LODs below 0.10 U mL-1 were obtained from calibration curves built in neutral buffer and diluted artificial serum, using DPV technique, enabling the detection of the protein biomarker at clinically relevant levels. The developed MIP biosensor was applied to the determination of CA 15-3 in spiked serum samples with satisfactory results. The developed device provides a new strategy for sensitive, rapid, simple and cost-effective screening of CA 15-3 biomarker. Importantly, the overall approach seems suitable for point-of-care (PoC) use in clinical context.

AB - Functionalization of pi-conjugated polymers is dispensable for solubilization of the rigid and hydrophobic backbones in water. However, polymer aggregation is always present and leads to issues with complication and reproducibility in spectral properties. Herein, we reported a simple and robust method to make a series of conjugated polymer nanostructures by a crosslinking strategy. In favor of multivalency effect, polythionenes with various chain lengths were functionalized with branched polyethylenimine (PEI) via ester aminolysis reaction under mild conditions. Photophysical studies revealed the conjugated backbones could be well stabilized and dispersed in water. By taking advantage of intermolecular recognition interaction between copper ions and cationic PEI, we applied crosslinked polythiophenes as a nano probe at very low concentration (0.01 mg/mL) to fluorescently detect copper ions with high sensitivity up to 10 nM and selectivity over other metal ions in aqueous solutions, without occurrence of detectable aggregates. The overall performance of our nano probes outperforms reported water-soluble polymers-based probes, particularly in probe availability and manipulation as well as selective copper detection capability. PMID- 29571163 TI - Performance comparison between multienzymes loaded single and dual electrodes for the simultaneous electrochemical detection of adenosine and metabolites in cancerous cells. AB - The analytical performance of the multi enzymes loaded single electrode sensor (SES) and dual electrode sensor (DES) was compared for the detection of adenosine and metabolites. The SES was fabricated by covalent binding of tri-enzymes, adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP), and xanthine oxidase (XO) along with hydrazine (Hyd) onto a functionalized conducting polymer [2,2:5,2-terthiophene-3-(p-benzoic acid)] (pTTBA). The enzyme reaction electrode in DES was fabricated by covalent binding of ADA and PNP onto pTTBA coated on Au nanoparticles. The detection electrode in DES was constructed by covalent binding of XO and Hyd onto pTTBA coated on porous Au. Due to the higher amount (3.5 folds) of the immobilized enzymes and Hyd onto the DES than SES, and the lower Michaelis constant (Km) value for DES (28.7 uM) compared to SES (36.1 uM), the sensitivity was significantly enhanced for the DES (8.2 folds). The dynamic range obtained using DES was from 0.5 nM to 120.0 uM with a detection limit of 1.43 nM +/- 0.02, 0.76 nM +/- 0.02, and 0.48 nM +/- 0.01, for adenosine (AD), inosine (IN), and hypoxanthine (Hypo) respectively. Further, the DES was coupled with an electrochemical potential modulated microchannel for the separation and simultaneous detection of AD, IN, and Hypo in an extracellular matrix of cancerous (A549) and non-cancerous (Vero) cells. The sensor probe confirms a higher basal level of extracellular AD and its metabolites in cancer cells compared to normal cells. In addition, the effect of dipyridamole on released adenosine in A549 cells was investigated. PMID- 29571164 TI - Single-molecule porphyrin-metal ion interaction and sensing application. AB - It remains a significant challenge to study the interactions between metal ions and porphyrin molecules at single ion level. Here, we constructed a nanopore based sensing for label-free and real-time analysis of the interaction between Cu2+ and 5,10,15,20-tetrakis(4-sulfonatophenyl)-porphyrin (TPPS). The results demonstrate that emerging electronic signatures of the Cu2+-TPPS complex that is completely different form the original free TPPS were observed in the alpha hemolysin (alpha-HL) nanopore. Based on the distinctive electronic signal patterns between TPPS and Cu2+-TPPS complex, the unique nanopore sensor can achieve a highly sensitive detection of Cu2+ in aqueous media. The frequency of signature events showed a linear response toward the concentration of Cu2+ in the range of 0.03 uM - 1.0 MUM, with a detection limit of 16 nM (S/N = 3). The sensing system also exhibited high selectivity against other metal ions, and the feasibility of this approach for practical applications was demonstrated with the determination of Cu2+ in running water. PMID- 29571166 TI - Incidence of female homicide in the Transkei sub-region of South Africa (1993 2015). AB - BACKGROUND: Female homicide is very complex and difficult to research. Xhosa women are poor, illiterate and live in a rural area where they are exposed to a number of risks to their lives. The previous apartheid regimen broke the fabric of the family value system in this region and this came on top of a traditional patriarchal view of women as little more than property. Women are most vulnerable in this traumatised society. OBJECTIVE: To study the incidence of female homicide in the Transkei sub-region of South Africa. METHOD: A record review was undertaken of all medico-legal autopsies performed from 1993 to 2015 at Mthatha Forensic Pathology Laboratory. RESULTS: In total, 26 972 autopsies were performed on victims of unnatural death between 1993 and 2015. Of these, 6091 (22.58%) were cases of unnatural death among females. Homicide accounted for 1865 (30.61%) of these deaths. The average rate of female homicide during the study period was 12.5 per 100 000. The rate of homicide decreased from 14.25/100 000 (1993) to 9.19/100 000 (2015). The average rate of death was 4.93/100 000 as a result of the use of firearms, 3.75/100 000 for stab injuries and 3.70/100 000 for blunt trauma. The rate of murder was highest (6.55/100 000) in the young age group between 11 and 40 years. CONCLUSION: Despite a one and half time decrease in the rate of female homicide in the last 23 years (1993-2015) in the Transkei sub region of South Africa, it is still three times higher than the worldwide rate. PMID- 29571165 TI - Structural model, functional modulation by ivermectin and tissue localization of Haemonchus contortus P-glycoprotein-13. AB - Haemonchus contortus, one of the most economically important parasites of small ruminants, has become resistant to the anthelmintic ivermectin. Deciphering the role of P-glycoproteins in ivermectin resistance is desirable for understanding and overcoming this resistance. In the model nematode, Caenorhabditis elegans, P glycoprotein-13 is expressed in the amphids, important neuronal structures for ivermectin activity. We have focused on its ortholog in the parasite, Hco-Pgp-13. A 3D model of Hco-Pgp-13, presenting an open inward-facing conformation, has been constructed by homology with the Cel-Pgp-1 crystal structure. In silico docking calculations predicted high affinity binding of ivermectin and actinomycin D to the inner chamber of the protein. Following in vitro expression, we showed that ivermectin and actinomycin D modulated Hco-Pgp-13 ATPase activity with high affinity. Finally, we found in vivo Hco-Pgp-13 localization in epithelial, pharyngeal and neuronal tissues. Taken together, these data suggest a role for Hco-Pgp-13 in ivermectin transport, which could contribute to anthelmintic resistance. PMID- 29571167 TI - The association between type of spine fracture and the mechanism of trauma: A useful tool for identifying mechanism of trauma on legal medicine field. AB - BACKGROUND: Determining the association between mechanism of trauma, and the type of spine column fracture is a useful approach for exactly describing spine injury on forensic medicine field. We aimed to determine mechanism of trauma based on distribution of the transition of spinal column fractures. METHODS: This cross sectional survey was performed on 117 consecutive patients with the history of spinal trauma who were admitted to emergency ward of Rasoul-e-Akram Hospital in Tehran, Iran from April 2015 to March 2016. The baseline characteristics were collected by reviewing the hospital recorded files. RESULTS: With respect to mechanism of fracture, 63.2% of fractures were caused by falling, 30.8% by collisions with motor vehicles, and others caused by the violence. Regarding site of fracture, lumbosacral was affected in 47.9%, thoracic in 29.9%, and cervical in 13.7%. Regarding type of fracture, burst fracture was the most common type (71.8%) followed by compressive fracture (14.5%). The site of fracture was specifically associated with the mechanism of injury; the most common injuries induced by falling from height were found in lumbosacral and cervical sites, and the most frequent injuries by traffic accidents were found in thoracic site; also the injuries following violence were observed more in lumbar vertebrae. The burst fractures were more revealed in the patients affected by falling from height and by traffic accidents, and both burst and compressive fractures were more observed with the same result in the patients injured with violence (p = 0.003). CONCLUSION: The type of spine fracture due to trauma is closely associated with the mechanism of trauma that can be helpful in legal medicine to identify the mechanism of trauma in affected patients. PMID- 29571168 TI - Two-phase high solid anaerobic digestion with dewatered sludge: Improved volatile solid degradation and specific methane generation by temperature and pH regulation. AB - The effects of temperature and pH on volatile solid (VS) degradation and CH4 production of anaerobic digestion treating high-solid municipal dewatered sludge was studied. There were two single-phase reactors in Group 1: 35 and 55 degrees C reactors. In Group 2 (G2), acidification phase temperature was 55 degrees C or 70 degrees C and digestion phase temperature was 35 degrees C or 55 degrees C. G3 was set on the basis of G2 with the initial pH adjusted to 10.0. VS degradation ratio and CH4 generation ratio of G2 and G3 were higher than G1. In G2, acidification reactors did not show much difference on VS degradation and CH4 generation. Higher VS degradation ratio with higher CH4 generation ratio was get in extreme thermophilic/thermophilic-mesophilic systems. In G3, pH adjustment only promoted VS degradation and CH4 generation in acidification reactors when compared to G2, but the two ratios of the whole systems was not further enhanced. PMID- 29571169 TI - Cake layer bacterial communities during different biofouling stages in full-scale membrane bioreactors. AB - A detailed understanding of the bacterial communities in the cake layers formed on the membrane surface is required to control biofouling in a membrane bioreactor (MBR). This study aimed to investigate the dynamics of the cake layer bacterial communities in full-scale MBRs operated in a wastewater treatment plant in Japan and to identify the key bacteria responsible for cake layer formation. The bacterial communities in the cake layer and the activated sludge were analyzed using 16S rRNA gene amplicon sequencing when biofouling occurred under different fouling conditions. The most dominant phyla in activated sludge were almost always Proteobacteria and Bacteroidetes. By contrast, when the cake layer had unique bacterial communities distinguishable from those in the activated sludge, members of Firmicutes were highly dominant in the cake layer, irrespective of the fouling conditions. This study reported for the first time that Firmicutes play an important role throughout the biofouling process. PMID- 29571170 TI - 4-Chlorophenol biodegradation facilitator composed of recombinant multi biocatalysts immobilized onto montmorillonite. AB - A biodegradation facilitator which catalyzes the initial steps of 4-chlorophenol (4-CP) oxidation was prepared by immobilizing multiple enzymes (monooxygenase, CphC-I and dioxygenase, CphA-I) onto a natural inorganic support. The enzymes were obtained via overexpression and purification after cloning the corresponding genes (cphC-I and cphA-I) from Arthrobacter chlorophenolicus A6. Then, the recombinant CphC-I was immobilized onto fulvic acid-activated montmorillonite. The immobilization yield was 60%, and the high enzyme activity (82.6%) was retained after immobilization. Kinetic analysis indicated that the Michaelis Menten model parameters for the immobilized CphC-I were similar to those for the free enzyme. The enzyme stability was markedly enhanced after immobilization. The immobilized enzyme exhibited a high level of activity even after repetitive use (84.7%) and powdering (65.8%). 4-CP was sequentially oxidized by a multiple enzyme complex, comprising the immobilized CphC-I and CphA-I, via the hydroquinone pathway: oxidative transformation of 4-CP to hydroxyquinol followed by ring fission of hydroxyquinol. PMID- 29571171 TI - Mixing effects on the kinetics and the dynamics of two-phase enzymatic hydrolysis of hemicellulose for biofuel production. AB - This work uses a coupled experimental and modeling approach to explore the effects of macro- and micro-mixing on the kinetics and the dynamics of two-phase enzymatic hydrolysis of hemicellulose. Reactor mixing does not alter the non competitive nature of product inhibition in hemicellulose hydrolysis by endoxylanase, but produces stronger inhibition that reduces the soluble sugar yield by 8-14.5%, as the mixing speed increases from 0 to 200 rpm. The kinetic constants (Km, Vmax, Kx) assume mass-transfer disguised values at 0-200 rpm. An optimal mixing strategy, comprising of 55-70 min of initial rapid convective macromixing followed by diffusive micromixing (without any macromixing) for the rest of the hydrolysis, increases xylose and reducing sugar yields by 6.3-8% and 13-20%, respectively, over continuous mixing at 200 rpm, for 1-5 mg/ml substrate loading at an optimum enzyme to substrate ratio of 1:20, with an energy saving of 94-96% over 24 h. PMID- 29571172 TI - Management of high-risk breast lesions found on mammogram or ultrasound: the value of contrast-enhanced MRI to exclude malignancy. AB - PURPOSE: To evaluate the performance of magnetic resonance imaging (MRI) to exclude malignancy in biopsy-proven high-risk breast lesions prior to surgical excision. MATERIAL AND METHODS: Breast MRIs performed after a core needle biopsy (CNB) yielding high-risk pathology were evaluated for the presence of suspicious enhancement. The diagnostic performance of MRI to exclude malignancy was calculated. RESULTS: The average reader sensitivity, specificity, negative predictive value, positive predictive value and accuracy of MRI were 92%, 51%, 98%, 22% and 56%, respectively. CONCLUSION: Lack of enhancement on MRI at the site of a high-risk lesion was useful for excluding malignancy. PMID- 29571173 TI - Seizure Freedom in Patients with Dravet Syndrome with Contraceptives: A Case Report with Two Patients. AB - Dravet syndrome is a rare and malignant epileptic syndrome that is typically resistant to antiepileptic drugs. There is a growing interest in the antiepileptic properties of neurosteroids. Especially progesterone is known to act as an anticonvulsive agent. However, contraceptives that act as orally given neurosteroids often lead to increased seizures in women with epilepsy.We report on two girls with Dravet syndrome, who gained seizure freedom under therapy with contraceptives. The first patient received an oral contraceptive, a combination of an estrogen, and a gestagen, due to hypermenorrhea. The second received a pure gestagen implant for contraception.The antiepileptic effect of progesterone is mainly attributed to its conversion into allopregnanolone and related neurosteroids, which are positive modulators of gamma-aminobutyric acid A receptors. It is unclear whether the observed effect of these contraceptives containing synthetic progesterone derivatives may be specific for the Dravet syndrome, and it is unclear whether and how this observation can be used therapeutically. PMID- 29571174 TI - Integration of Biochemometrics and Molecular Networking to Identify Antimicrobials in Angelica keiskei. AB - Botanical medicines have been utilized for centuries, but it remains challenging to identify bioactive constituents from complex botanical extracts. Bioassay guided fractionation is often biased toward abundant or easily isolatable compounds. To comprehensively evaluate active botanical mixtures, methods that allow for the prioritization of active compounds are needed. To this end, a method integrating bioassay-guided fractionation, biochemometric selectivity ratio analysis, and molecular networking was devised and applied to Angelica keiskei to comprehensively evaluate its antimicrobial activity against Staphylococcus aureus. This approach enabled the identification of putative active constituents early in the fractionation process and provided structural information for these compounds. A subset of chalcone analogs were prioritized for isolation, yielding 4-hydroxyderricin (1, minimal inhibitory concentration [MIC] <= 4.6 uM, IC50 = 2.0 uM), xanthoangelol (2, MIC <= 4.0 uM, IC50 = 2.3) and xanthoangelol K (4, IC50 = 168 uM). This approach allowed for the identification of a low-abundance compound (xanthoangelol K) that has not been previously reported to possess antimicrobial activity and facilitated a more comprehensive understanding of the compounds responsible for A. keiskei's antimicrobial activity. PMID- 29571175 TI - Development and validation of the SIMPLE endoscopic classification of diminutive and small colorectal polyps. AB - BACKGROUND: Prediction of histology of small polyps facilitates colonoscopic treatment. The aims of this study were: 1) to develop a simplified polyp classification, 2) to evaluate its performance in predicting polyp histology, and 3) to evaluate the reproducibility of the classification by trainees using multiplatform endoscopic systems. METHODS: In phase 1, a new simplified endoscopic classification for polyps - Simplified Identification Method for Polyp Labeling during Endoscopy (SIMPLE) - was created, using the new I-SCAN OE system (Pentax, Tokyo, Japan), by eight international experts. In phase 2, the accuracy, level of confidence, and interobserver agreement to predict polyp histology before and after training, and univariable/multivariable analysis of the endoscopic features, were performed. In phase 3, the reproducibility of SIMPLE by trainees using different endoscopy platforms was evaluated. RESULTS: Using the SIMPLE classification, the accuracy of experts in predicting polyps was 83 % (95 % confidence interval [CI] 77 % - 88 %) before and 94 % (95 %CI 89 % - 97 %) after training (P = 0.002). The sensitivity, specificity, positive predictive value, and negative predictive value after training were 97 %, 88 %, 95 %, and 91 %. The interobserver agreement of polyp diagnosis improved from 0.46 (95 %CI 0.30 - 0.64) before to 0.66 (95 %CI 0.48 - 0.82) after training. The trainees demonstrated that the SIMPLE classification is applicable across endoscopy platforms, with similar post-training accuracies for narrow-band imaging NBI classification (0.69; 95 %CI 0.64 - 0.73) and SIMPLE (0.71; 95 %CI 0.67 - 0.75). CONCLUSIONS: Using the I-SCAN OE system, the new SIMPLE classification demonstrated a high degree of accuracy for adenoma diagnosis, meeting the ASGE PIVI recommendations. We demonstrated that SIMPLE may be used with either I-SCAN OE or NBI. PMID- 29571177 TI - Large In-mask Motion during Frameless Radiosurgery of a Brain Metastasis. AB - Frameless radiosurgery is now a common alternative to traditional in-frame treatment. Several dosimetric studies have reported small in-mask positioning inaccuracies during frameless radiosurgery. We present a case of an uncommonly large deviation in in-mask motion detected offline in a patient undergoing linear accelerator-based frameless radiosurgery. Our case illustrates how the use of a thermoplastic mask can lead to unacceptable setup errors for passive image-guided radiosurgery. The case underlines the need for correct patient preparation, adequate time between mask molding and computed tomography, and routine intrafraction imaging. Image-guided positioning is recommended to achieve clinically acceptable setup accuracy (< 1 mm) for stereotactic radiosurgery. PMID- 29571176 TI - Intraoperative Ultrasound Appearance of a Pancreatic Cerebral Metastasis: A Case Report. AB - BACKGROUND: Brain metastases (BMs) derived from pancreatic adenocarcinoma (PAC) have an extremely low incidence (0.1-0.4%) and are usually associated with a very poor prognosis. The treatment strategy is palliative and includes conventional radiotherapy, stereotactic radiosurgery, chemotherapy, and surgical resection. CASE DESCRIPTION: A 39-year-old man with a history of PAC developed a systemic tumor relapse with intracranial progression. Magnetic resonance imaging (MRI) documented a right rolandic, cortical, and cystic lesion with leptomeningeal intrasulcular extension. The intraoperative ultrasound (iUS) depicted a hyperechogenic area surrounding the anechogenic cystic lesion and allowed us to obtain gross total resection of the tumor. CONCLUSIONS: To the best of our knowledge, we describe for the first time the iUS aspect of a pancreatic BM. In this case the use of iUS allowed us to increase the extent of resection and surgical safety, thus reducing the risk of new postoperative neurologic deficits. PMID- 29571178 TI - ?

AB - In recent years, rapid advances are achieved in polymer solar cells (PSCs) using nonfullerene small molecular acceptors. However, no research disclosing the influence of molecular weight (Mn ) of conjugated polymer on the nonfullerene device performance is reported. In this work, a series of polymers with different Mn s are synthesized to systematically investigate the connection between Mn and performance of nonfullerene devices for the first time. It is found that the device performance improves substantially as the Mn increases from 12 to 38 kDa and a power conversion efficiency (PCE) as high as 10.5% is realized. It has to be noted this PCE is achieved without using any additives and post-treatments, which is among the top efficiencies of additive- and post-treatment-free PSCs. Most importantly, the variation trend of the optimal active layer thickness and morphology is significantly different from the device with fullerene as acceptor. The findings clarify the effect of Mn on the performance of nonfullerene PSCs, which would benefit further efficiency improvement of nonfullerene PSCs. PMID- 29571215 TI - Molybdenum Carbide-Decorated Metallic Cobalt@Nitrogen-Doped Carbon Polyhedrons for Enhanced Electrocatalytic Hydrogen Evolution. AB - Electrocatalytic hydrogen evolution reaction (HER) based on water splitting holds great promise for clean energy technologies, in which the key issue is exploring cost-effective materials to replace noble metal catalysts. Here, a sequential chemical etching and pyrolysis strategy are developed to prepare molybdenum carbide-decorated metallic cobalt@nitrogen-doped porous carbon polyhedrons (denoted as Mo/Co@N-C) hybrids for enhanced electrocatalytic hydrogen evolution. The obtained metallic Co nanoparticles are coated by N-doped carbon thin layers while the formed molybdenum carbide nanoparticles are well-dispersed in the whole Co@N-C frames. Benefiting from the additionally implanted molybdenum carbide active sites, the HER performance of Mo/Co@N-C hybrids is significantly promoted compared with the single Co@N-C that is derived from the pristine ZIF-67 both in alkaline and acidic media. As a result, the as-synthesized Mo/Co@N-C hybrids exhibit superior HER electrocatalytic activity, and only very low overpotentials of 157 and 187 mV are needed at 10 mA cm-2 in 1 m KOH and 0.5 m H2 SO4 , respectively, opening a door for rational design and fabrication of novel low cost electrocatalysts with hierarchical structures toward electrochemical energy storage and conversion. PMID- 29571216 TI - Metal-Ion-Mediated Supramolecular Chirality of l-Phenylalanine Based Hydrogels. AB - For chiral hydrogels and related applications, one of the critical issues is how to control the chirality of supramolecular systems in an efficient way, including easy operation, efficient transfer of chirality, and so on. Herein, supramolecular chirality of l-phenylalanine based hydrogels can be effectively controlled by using a broad range of metal ions. The degree of twisting (twist pitch) and the diameter of the chiral nanostructures can also be efficiently regulated. These are ascribed to the synergic effect of hydrogen bonding and metal ion coordination. This study may develop a method to design a new class of electronically, optically, and biologically active materials. PMID- 29571217 TI - Chemistry of Metallacyclobutadienes. AB - Metallacyclobutadienes are analogues of cyclobutadienes in which one of the cyclobutadiene CR groups has been formally replaced by a transition-metal fragment. These metallacycles are interesting because they can play an important role in catalysis and can serve as starting materials for the syntheses of organometallic compounds such as metallabenzene, eta5 -cyclopentadienyl, and eta3 -cyclopropenyl complexes. Unlike cyclobutadienes, metallacyclobutadienes can be significantly more stable. A number of metallacyclobutadienes have now been isolated and thoroughly characterized, especially for those that contain transition metals of groups 5-9. Their properties have also been actively investigated. This article highlights the chemistry of metallacyclobutadienes with reference to their syntheses, reactivity, and structural properties.

Whereas monometallic Pd and Au catalysts were totally ineffective, Pd-Au alloy nanoparticle catalysts with a low Pd/Au molar ratio showed high activity to give the corresponding polysubstituted arenes in high yields. A variety of substituted alkynes participated in various modes of cycloaddition under Pd-Au alloy catalysis. The Pd-Au alloy catalysts exhibited high air tolerance and reusability. PMID- 29571219 TI - Plasticity of mycangia in Xylosandrus ambrosia beetles. AB - Insects that depend on microbial mutualists evolved a variety of organs to transport the microsymbionts while dispersing. The ontogeny and variability of such organs is rarely studied, and the microsymbiont's effects on the animal tissue development remain unknown in most cases. Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae or Platypodinae) and their mutualistic fungi are an ideal system to study the animal-fungus interactions. While the interspecific diversity of their fungus transport organ-mycangia-is well-known, their developmental plasticity has been poorly described. To determine the ontogeny of the mycangium and the influence of the symbiotic fungus on the tissue development, we dissected by hand or scanned with micro-CT the mycangia in various developmental stages in five Xylosandrus ambrosia beetle species that possess a large, mesonotal mycangium: Xylosandrus amputatus, Xylosandrus compactus, Xylosandrus crassiusculus, Xylosandrus discolor, and Xylosandrus germanus. We processed 181 beetle samples from the United States and China. All five species displayed three stages of the mycangium development: (1) young teneral adults had an empty, deflated and cryptic mycangium without fungal mass; (2) in fully mature adults during dispersal, the pro-mesonotal membrane was inflated, and most individuals developed a mycangium mostly filled with the symbiont, though size and symmetry varied; and (3) after successful establishment of their new galleries, most females discharged the bulk of the fungal inoculum and deflated the mycangium. Experimental aposymbiotic individuals demonstrated that the pronotal membrane invaginated independently of the presence of the fungus, but the fungus was required for inflation. Mycangia are more dynamic than previously thought, and their morphological changes correspond to the phases of the symbiosis. Importantly, studies of the fungal symbionts or plant pathogen transmission in ambrosia beetles need to consider which developmental stage to sample. We provide illustrations of the different stages, including microphotography of dissections and micro-CT scans. PMID- 29571220 TI - Shaping nursing profession regulation through history - a systematic review. AB - AIM: The aim of this systematic review was to provide a critical synthesis of the factors that historically shaped the advancements of nursing regulators worldwide. BACKGROUND: An in-depth examination of the different factors that moulded regulatory changes over time is pivotal to comprehend current issues in nursing. INTRODUCTION: In the light of global health scenarios, the researchers explored the factors that historically influenced the socio-contextual circumstances upon which governments made regulatory changes. METHODS: A systematic search was performed on the following databases: PubMed, CINAHL, Scopus, OpenGrey and ScienceDirect. The review included papers from January 2000 to October 2016 published in English. The authors used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and an inductive thematic approach for synthesis. RESULTS: Two main themes were identified: factors underpinning current challenges and historical and contextual triggers of regulation. The first theme was composed of three aspects: education, migration and internationalization, and policy and regulation; the second theme consisted of four attributes: demographics, economics, history of registration and wars, and historical changes in nursing practice. DISCUSSION: Factors that shaped nursing regulation were linked to changing demographics and economics, education, history of nursing registration, shifting patterns of migration and internationalization, nursing practice, policy and regulation and significant societal turns often prompted by wars. CONCLUSION: A deeper understanding of the developments of the nursing regulatory institutions provides the foundation for portable standards that can be applied across an array of jurisdictions to guarantee a better public safety. IMPLICATION FOR NURSING AND HEALTH POLICY: Understanding factors that socially, legislatively and politically have influenced the development of regulatory bodies over time helps to mould local, national and international policies that have a stronger impact on health worldwide. To achieve this, there must be effective cooperation among systems of nursing regulations globally.

AB - AIM: The objective of this study was to assess the impact of a simulation workshop on self-efficacy towards teaching for nurse educators in India. Additionally, we sought to revise and validate a tool to measure self-efficacy in teaching for use with a global audience. BACKGROUND: Simulation is an evidence based teaching and learning method and is increasingly used in nursing education globally. INTRODUCTION: As new technology and teaching methods such as simulation continue to evolve, it is important for new as well as experienced nurse educators globally to have confidence in their teaching skills and abilities. METHODS: The study included (1) instrument revision, and measures of reliability and validation, (2) an 8-h faculty development workshop intervention on simulation, (3) pre- and post-survey of self-efficacy among nurse educators, and (4) investigation of relationship between faculty socio-demographics and degree of self-efficacy. RESULTS: The modified tool showed internal consistency (r = 0.98) and was validated by international faculty experts. There were significant improvements in total self-efficacy (P < 0.001) and subscale scores among nurse educators after the simulation workshop intervention when compared to pre-survey results. No significant relationships were found between socio-demographic variables and degree of self-efficacy. DISCUSSION: Strong self-efficacy in teaching among nurse educators is crucial for effective learning to occur. CONCLUSIONS AND IMPLICATIONS FOR NURSING: Results indicated the simulation workshop was effective in significantly improving self-efficacy towards teaching for nurse educators using an internationally validated tool. IMPLICATIONS FOR NURSING POLICY: The Minister of Health in India recently called for improvements in nursing education. Introducing nursing education on simulation as a teaching method in India and globally to improve self-efficacy among teachers is an example of a strategy towards meeting this call.

AB - Defect engineering in 2D phosphorene samples is becoming an important and powerful technique to alter their properties, enabling new optoelectronic applications, particularly at the infrared wavelength region. Defect engineering in a few-layer phosphorene sample via introduction of substrate trapping centers is realized. In a three-layer (3L) phosphorene sample, a strong photoluminescence (PL) emission peak from localized excitons at ~1430 nm is observed, a much lower energy level than free excitonic emissions. An activation energy of ~77 meV for the localized excitons is determined in temperature-dependent PL measurements. The relatively high activation energy supports the strong stability of the localized excitons even at elevated temperature. The quantum efficiency of localized exciton emission in 3L phosphorene is measured to be approximately three times higher than that of free excitons. These results could enable exciting applications in infrared optoelectronics.

AB - AIMS: To examine burnout and work engagement among nurses in Japanese long-term care hospitals and their relation to nurses' and organisational work values, and nurse-organisation congruence of such values. BACKGROUND: Nursing managers must help improve nurses' well-being; however, no research has considered strategies to improve staff outcomes in long-term care hospitals. We propose that individual nurse's work values and the congruence of these values with those of their organisations may influence burnout and work engagement. METHODS: We conducted a cross-sectional survey of nurses in long-term care hospitals. Multiple regression analyses were conducted to examine the effects of nurses' work values and nurse organisation congruence in these values on burnout and work engagement. RESULTS: Higher individual intrinsic and altruistic work values were associated with improvements in nurses' burnout and work engagement. Nurse-organisation non congruence in altruistic values was associated with lower work engagement, whereas that of intrinsic work values was not associated with either outcome variable. CONCLUSION: Promoting intrinsic and altruistic work values among nurses could be effective for improving both burnout and work engagement. IMPLICATIONS FOR NURSING MANAGEMENT: Opportunities such as case conferences could foster intrinsic and altruistic work values through the review of good care practices and communication between managers/colleagues about feelings and thoughts.

AB - The electronic structure of metal clusters is notoriously difficult to detect spectroscopically, due to rapid relaxation into the ground state following excitation. We have used IR multiple photon excitation to identify a low-lying electronic state in a tantalum carbide cluster. The electronic excitation is found at 458 cm-1 , and is confirmed by experiments on isotopically labeled clusters. Time-dependent density functional theory (TD-DFT) calculations confirm the current assignment, but a second predicted electronic state was not observed. PMID- 29571226 TI - The Hyperbaric Oxygen Therapy Registry: Driving quality and demonstrating compliance. AB - Objective: To provide an update on the status of provider participation in the US Wound Registry (USWR) and its specialty registry the Hyperbaric Oxygen Therapy Registry (HBOTR), which provide much-needed national benchmarking and quality measurement services for hyperbaric medicine. Methods: Providers can meet many requirements of the Merit-Based Incentive Payment System (MIPS) and simultaneously participate in the HBOTR by transmitting Continuity of Care Documents (CCDs) directly from their certified electronic health record (EHR) or by reporting hyperbaric quality measures, the specifications for which are available free of charge for download from the registry website as electronic clinical quality measures for installation into any certified EHR. Computerized systems parse the structured data transmitted to the USWR. Patients undergoing hyperbaric oxygen (HBO2) therapy are allocated to the HBOTR and stored in that specialty registry database. The data can be queried for benchmarking, quality reporting, public policy, or specialized data projects. Results: Since January 2012, 917,758 clinic visits have captured the data of 199,158 patients in the USWR, 3,697 of whom underwent HBO2 therapy. Among 27,404 patients with 62,843 diabetic foot ulcers (DFUs) captured, 9,908 DFUs (15.7%) were treated with HBO2 therapy. Between January 2016 and September 2018, the benchmark rate for the 1,000 DFUs treated with HBO2 was 7.3%, with an average of 28 treatments per patient. There are 2,100 providers who report data to the USWR by transmitting CCDs from their EHR and 688 who submit quality measure data, 300 (43.6%) of whom transmit HBO2 quality data. PMID- 29571227 TI - Impact of hyperbaric oxygenation on oxidative stress in diabetic patients. AB - Taking into consideration that a high concentration of oxygen can express toxic effects due to production of reactive oxygen species (ROS), the aim of our investigation was to establish the influence of hyperbaric oxygenation on oxidative stress parameters and antioxidant enzymes in patients with diabetes mellitus (DM) type 2. Investigation included 50 patients with DM type 2 divided into two groups. The first group consisted of 25 patients, mean age 70 years, mean duration of illness 12 years and without manifest peripheral vascular complications (Wagner 0). The second group consisted of 25 patients, mean age 74 years, mean duration of illness 17 years and with manifest peripheral vascular complications (Wagner 1-5). All patients underwent the same therapeutic protocol, which included 10 hyperbaric oxygenation therapies, once a day for a duration of 60 minutes, with an average partial oxygen pressure of 1.7 atmospheres absolute (ATA). In blood samples the following parameters of redox balance were determined: levels of nitrites (NO2-), index of lipid peroxidation (TBARS), superoxide anion radical (O2-), hydrogen peroxide (H2O2) and antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Our results clearly show that hyperbaric oxygen (HBO2) therapy does not have a pro-oxidative effect. Additionally, it seems that this procedure strongly mobilized the antioxidant enzyme system, thus improving defense from oxidative damage. All significant data are marked as P ?0.05. Our results have shown that in terms of ROS production, HBO2 can be safe to use in patients suffering from DM type 2 with or without vascular complications. PMID- 29571225 TI - Folic acid delays development of atherosclerosis in low-density lipoprotein receptor-deficient mice. AB - Many studies support the cardioprotective effects of folic acid (FA). We aimed to evaluate the utility of FA supplementation in preventing the development of atherosclerotic in low-density lipoprotein receptor-deficient (LDLR-/-) mice and to elucidate the molecular processes underlying this effect. LDLR-/- mice were randomly distributed into four groups: control group, HF group, HF + FA group and the HF + RAPA group. vascular smooth muscle cells (VSMCs) were divided into the following four groups: control group, PDGF group, PDGF + FA group and PDGF + FA + RAPA group. Blood lipid levels, oxidative stress and inflammatory cytokines were measured. Atherosclerosis severity was evaluated with oil red O staining. Haematoxylin and eosin (H&E) staining was used to assess atherosclerosis progression. Immunohistochemical staining was performed with antismooth muscle alpha-actin (alpha-SMA) antibodies and anti-osteopontin (OPN) antibodies that demonstrate VSMC dedifferentiation. The protein expression of alpha-SMA, OPN and mechanistic target of rapamycin (mTOR)/p70S6K signalling was detected by Western blot analysis. FA and rapamycin reduced serum levels of total cholesterol, triacylglycerol, LDL, inhibiting oxidative stress and the inflammatory response. Oil red O and H&E staining demonstrated that FA and rapamycin inhibited atherosclerosis. FA and rapamycin treatment inhibited VSMC dedifferentiation in vitro and in vivo, and FA and rapamycin attenuated the mTOR/p70S6K signalling pathway. Our findings suggest that FA attenuates atherosclerosis development and inhibits VSMC dedifferentiation in high-fat-fed LDLR-/- mice by reduced lipid levels and inhibiting oxidative stress and the inflammatory response through mTOR/p70S6K signalling pathway. PMID- 29571228 TI - An anti-barotrauma system for preventing barotrauma during hyperbaric oxygen therapy. AB - In the present study, a tympanometry-based anti-barotrauma (ABT) device was designed using eardrum admittance measurements to develop an objective method of preventing barotrauma that occurs during hyperbaric oxygen (HBO2) therapy. The middle ear space requires active equalization, and barotrauma of these tissues during HBO2therapy constitutes the most common treatment-associated injury. Decongestant nasal sprays and nasal steroids are used, but their efficacy is questionable to prevent middle ear barotrauma (MEB) during HBO2 treatment. Accordingly, a tympanometry-based ABT device was designed using eardrum admittance measurements to develop an objective method for preventing MEB, which causes pain and injury, and represents one of the principal reasons for patients to stop treatment. This study was conducted to test a novel technology that can be used to measure transmembrane pressures, and provide chamber attendants with real-time feedback regarding the patient's equalization status prior to the onset of pain or injury. Eardrum admittance values were measured according to pressure changes inside a hyperbaric oxygen chamber while the system was fitted to the subject. When the pressure increased to above 200 daPa, eardrum admittance decreased to 16.255% of prepressurization levels. After pressure equalization was achieved, eardrum admittance recovered to 95.595% of prepressurization levels. A one-way repeated measures analysis of variance contrast test was performed on eardrum admittance before pressurization versus during pressurization, and before pressurization versus after pressure equalization. The analysis revealed significant differences at all points during pressurization (P?0.001), but no significant difference after pressure equalization was achieved. This ABT device can provide objective feedback reflecting eardrum condition to the patient and the chamber operator during HBO2 therapy. PMID- 29571229 TI - Hyperbaric oxygen therapy as adjuvant for treating wound complications after extensive resection for vulvar malignancy. AB - Introduction: Necrosis, wound breakdown, and infection represent major complications associated with radical vulvectomy. We aimed to analyze the feasibility of hyperbaric oxygen (HBO2) therapy as an adjunctive treatment for such complications. Methods: We performed a retrospective analysis of the medical records, clinical charts, and operative records of vulvar cancer patients who underwent hyperbaric oxygen therapy after extensive surgical resection in our institute between 2012 and 2016, with a comparison of the clinical outcomes of patients with similar surgical procedures andsevere wound complications who did not undergo HBO2. Results: A total of 16 patients were included in the study. In the subgroup treated with HBO2, seven patients were identified. Two patients had primary surgery, while five had recurrent surgery (of these, two had previously undergone radiation therapy). Six patients received reconstructive flaps (five myocutaneous and onefasciocutaneous), while one patient had primary suture. Dehiscence, ischemia and necrosis were estimated to cover 30%-80% of the surgical surface area. Surgical debridement was performed in six patients. Daily 90-minute sessions in the hyperbaric chamber were performed at a pressure of 2.2 atmospheres absolute, with partial oxygen pressure of 1672 mbar. Infection control and satisfactory healing were achieved using 10-61 sessions. All patients in the subgroup who did not receive HBO2 required surgical debridement due to partial or near-total flap necrosis, with two reconstructive interventions required. Conclusions: Hyperbaric oxygen therapy was an efficient adjuvant for wound healing and infection control in managing wound complications after extensive vulvar resections. PMID- 29571230 TI - Analysis of factors related to failure in the pressure test: a six-year experience in Taiwan. AB - Introduction: The Republic of China Navy instituted the pressure test as one of the selection tools for diving troops and submarine crews. We analyzed factors associated with failure in the pressure test. Methods: This was a retrospective cohort study designed to investigate pressure test failure in Navy recruits between January 2010 and August 2015. The recruits received pressurization in a hyperbaric chamber to a simulated depth of 112 feet of seawater (fsw) at a rate of 25 fsw/minute. Data describing trainee demographics, disease history, causes and depth of failure, as well as type of injury, were extracted from case notes and facility databases for statistical analysis. Results: Of 3,608 trial cohorts, there were 435 failures, with an overall failure rate of 12.06%. About 95% of these failure trials were within a simulated depth of 60 fsw. Fifty-seven (57) failures did not record causes of failure. Among the other 378 failures, the most commonly identified causes were ear barotrauma (365 trials, 96.56%) and sinus barotrauma (10 trials, 2.65%). Statistical analysis revealed that recent upper respiratory tract infection, allergic rhinitis, and cigarette smoking were all significantly associated with higher incidence of middle ear barotrauma. Conclusions: Our results suggest that pressure testing to a depth of 60 fsw is effective in disqualifying personnel entering diving and submarine service. Recent infection of the upper respiratory tract, allergic rhinitis and cigarette smoking are risk factors for middle ear barotrauma, resulting in failure of the pressure test. PMID- 29571231 TI - A case-control questionnaire survey of decompression sickness risk in Okinawa divers. AB - Background: Decompression sickness (DCS) is a rare condition that is often difficult to diagnose in deep-sea divers. Because of this, prevention and early diagnosis are important. In this case-control study, we examined the risk and preventive factors associated with DCS. Methods: Our original questionnaire survey was conducted among 269 recreational divers in Okinawa. Divers who were diagnosed with DCS by a physician (n = 94) were compared with healthy recreational divers (n = 175). The questionnaire consisted of 30 items and included a dive profile. Odds ratios and multiple logistic regression analysis were used to estimate the relative risk of DCS. Results: Logistic regression analysis revealed the following risk factors for DCS: a past history of DCS, drinking alcohol the evening before diving, indicating decompression stops, cold exposure after the dive, and maximum depth. Preventive factors included hydration before the dive, deep stops, safety stops and using nitrox gas. The results were reliable according to the Hosmer-Lemeshow and omnibus tests. Conclusion: We identified certain risk factors, together with their relative risks, for DCS. These risk factors may facilitate prevention of DCS among Okinawa divers. PMID- 29571232 TI - Influence of exposure in hyperbaric chambers on selected parametersof oxidative stress in professional divers. AB - Purpose: This study evaluated the influence of hyperbaric exposure chambers on selected parameters of oxidative stress in divers' blood. Methods: 25 healthy men (non-smoking experienced divers) ages 18-40 took part in the experiment. Subjects were exposed to hyperbaric conditions similar to those at 30 meters of depth while diving. A control group consisted of 20 healthy men who have never dived or been exposed to hyperbaric conditions. Blood was drawn from the cubital vein after overnight fasting. Superoxide dismutase (SOD-1) activity and malondialdehyde (MDA) concentration were marked in red blood cells (RBCs), carbonyl group concentration marked in serum proteins, and nitrate/nitrite concentrations were estimated in plasma. Results: Statistically significant differences were found between the divers and the control group in MDA concentration in erythrocytes and carbonyl group concentration in serum proteins. Nitrite/nitrate concentrations in plasma plus SOD-1 activity in RBCs decreased significantly in the diver group compared with the control group. After hyperbaric exposure MDA concentration in erythrocytes increased considerably in the test group and a significant increase in SOD-1 activity was observed. A significant increase of nitrite/nitrate concentration was noted in plasma as well as an increase in the carbonyl group in serum proteins. Conclusion: Considerably weak enzymatic antioxidative defense was observed in the RBCs of individuals exposed to hyperbaric pressures versus those in normobary. This issue indicates that a diver's system has a larger susceptibility for negative effects from oxidative stress. The results also indicate that hyperbaric conditions can intensify reactions via free radicals. PMID- 29571233 TI - Blood lactate accumulation during competitive freediving and synchronized swimming. AB - A number of competitive water sports are performed while breath-holding (apnea). Such performances put large demands on the anaerobic system, but the study of lactate accumulation in apneic sports is limited. We therefore aimed to determine and compare the net lactate accumulation (NLA) during competition events in six disciplines of competitive freediving (FD) and three disciplines of synchronized swimming (SSW). The FD disciplines were: static apnea (STA; n = 14); dynamic apnea (DYN; n = 19); dynamic apnea no fins (DNF; n = 16); constant weight (CWT; n = 12); constant weight no fins (CNF; n = 8); free immersion (FIM; n =10). The SSW disciplines were solo (n = 21), duet (n = 31) and team (n = 34). Capillary blood lactate concentration was measured before and three minutes after competition performances, and apneic duration and performance variables were recorded. In all nine disciplines NLA was observed. The highest mean (SD) NLA (mmol.L-1) was found in CNF at 6.3 (2.2), followed by CWT at 5.9 (2.3) and SSW solo at 5 (1.9). STA showed the lowest NLA 0.7 (0.7) mmol.L-1 compared to all other disciplines (P ? 0.001). The NLA recorded shows that sports involving apnea involve high levels of anaerobic activity. The highest NLA was related to both work done by large muscle groups and long apneic periods, suggesting that NLA is influenced by both the type of work and apnea duration, with lower NLA in SSW due to shorter apneic episodes with intermittent breathing. PMID- 29571234 TI - Cervicocranial artery dissection and scuba diving: Is there a link or is it serendipity? AB - Introduction: Numerous reports have documented cervicocranial artery dissection (CCAD) associated with scuba diving. The question remains as to whether there are risk factors unique to scuba diving related to the occurrence of CCAD. Objectives: This article aims to perform an examination of the reported cases to demonstrate any commonality among the injured divers and association with known risk factors for CCAD. Methods: A PubMed search was performed utilizing the key words: carotid artery dissection, dissection, arterial dissection, cranial artery dissection, scuba, diving, scuba diving. Articles including reports, reviews, trials, case series, and letters were considered. Each report was critically dissected for information specific to the dive itself and the diver and analyzed for similarities and consistency with known risks. Results: Twelve (12) reports of CCAD associated with scuba diving were identified. Activities involved with scuba diving appear to be consistent with CCAD risk factors. It is unclear if hyperbaric stress and physiological changes during a dive present specific risk. Trauma - e.g., environmental protection and activities associated with diving - was identified as a common risk factor in all cases. Ten (10) cases involved arteries at anatomic sites commonly associated with dissections. Seven divers documented to have dive profiles suspicious of decompression sickness were identified. Conclusions: There appears to be a correlation with minor traumas that occur with diving and CCAD. The inconsistency of the dive-related specific information reported makes it impossible for investigation of hyperbaric stress related risk factors for CCAD to be analyzed. PMID- 29571235 TI - Do not fear the Framingham: Practical application to properly evaluate and modify cardiovascular risk in commercial divers. AB - Introduction: In April 2016 the Association of Diving Contractors International (ADCI) consensus guidelines began recommending annual cardiovascular risk stratification of commercial divers using the Framingham Risk Score (FRS). For those at elevated risk, further testing is recommended. This approach has raised concerns about potential operational and financial impacts. However, the prevalence of elevated cardiovascular risk and need for additional testing among commercial divers is not known. Methods: Clinical data required to calculate the FRS was abstracted for 190 commercial divers in two cohorts. Population demographics, FRS distribution, contributions of risk factors and effect of interventions on reducing risk-factor burden were assessed. Results: Mean FRS score was 1.68 +/- 6.35 points, with 13 divers (6.8%) at intermediate risk and none at high 10-year risk. In these 13 divers, the mean contributions to the FRS were from age (6.5 points), cholesterol (3.1 pts.), smoking (1.3 pts.), highdensity lipoprotein (1 pt.), and systolic blood pressure (0.8 pts). The youngest age group had a significantly higher modifiable risk core than the oldest age group (5.87 vs. 1.2 points, P ? 0.001). All 13 intermediate risk divers could have been reclassified as low-risk with successful treatment of modifiable risk factors. Discussion: The prevalence of elevated cardiovascular risk among commercial divers is low, and treatment of modifiable risk factors could reclassify those at intermediate risk to low risk. Therefore, FRS implementation coupled with intensive risk-reduction strategies for at risk divers may help improve diver health and prolong the careers of divers while limiting the need for additional testing and adverse operational impact. PMID- 29571236 TI - Hyperbaric oxygen for late sequelae of carbon monoxide poisoning enhances neurological recovery: case report. AB - Neuropsychiatric sequelae have been reported in 15%-45% of survivors of carbon monoxide (CO) poisoning. Hyperbaric oxygen (HBO2) therapy reduces the incidence of cognitive and neurological a dysfunction. The efficacy of providing HBO2 beyond the first one to two days after initial insult is unknown. However, some evidence exists for the benefit of this treatment. We report on treating a patient 14 months after CO injury, who responded with markedly improved neurologic status. A 27-year-old scholar was found comatose due to CO poisoning (carboxyhemoglobin = 31.7%). He received five acute HBO2 treatments. After discharge, he developed chorea, Parkinsonism, dystonia, memory loss, slowed processing speed and verbal fluency, leaving him disabled. After the patient reached a clinical plateau, HBO2 was tried again at 90 minutes at 2.4 ATA plus air breaks. Neuropsychological testing was performed at baseline and after each 20 HBO2 cycles, five of which were performed during the period from 14-22 months after CO exposure. After the first 20 treatments, Parkinsonism and dystonia improved. After 40 sessions, further improvements were seen on mental speed, verbal fluency, and fine motor movements. The outcome following 100 treatments was that the patient regained independence, including the ability to drive and to become gainfully employed. Our case calls into question the concept that HBO2 therapy has no role during the chronic phase of CO brain injury. Randomized clinical trials should be considered to evaluate the therapeutic efficacy of HBO2 in patients with neurological sequelae following CO injury. PMID- 29571237 TI - An approach to treating a patient with a HeartMate IITM left ventricularassist device in a multiplace hyperbaric chamber: a case report. AB - Introduction: Left-ventricular assist devices (LVAD) are becoming a common therapy for end-stage heart failure. These devicesare not tested for pressurization in a hyperbaricchamber by the manufacturer. In this article, we present an approach to modify the power supply in order to safely treat a patient with an LVAD. Materials and Methods: Our patient had a HeartMateIITM LVAD and presented for hyperbaric oxygen treatments for severe radiation cystitis. In order to modify this patient's equipment to be compliant with NFPA6 safety standards we made several modifications. In brief, this included eliminating the usage of lithium-ion batteries, modifying the cord to be compatible with Fink chamber outlets, and enclosing the power module in a nitrogen purge. We then used a mock circulatory system to test our modifications and make sure the LVAD continued to have appropriate flow rates. We then conducted training for staff and developed a disaster plan should the LVAD fail at any point. Results: Once we felt comfortable with the modifications and had a plan developed should any problems arise, we then proceeded to treat our patient in the hyperbaric chamber. He successfully underwent 44 hyperbaric treatments for radiation cystitis without complications. Conclusion: This case is the second reported patient in the literature with an LVAD that was successfully treated in a multiplace hyperbaric chamber. As LVADs become increasingly popular to manage heart failure, more patients with these devices will present for hyperbaric treatments. With a few modifications, an LVAD patient can be safely and successfully treated in a hyperbaric chamber.

AB - The vast clinical manifestations of carbon monoxide (CO) poisoning can involve the neurological, neuropsychological and cardiac systems as well as others. In this case report, we describe our management of a 64-year-old woman exposed to CO in her apartment. Her presentation was unusual in that she had symmetric globus pallidus lesions, no evidence of thrombosis, but the lateralizing neurologic manifestation of severe hemiplegia. PMID- 29571239 TI - Management of central retinal artery occlusion following successful hyperbaric oxygen therapy: case report. AB - Objective: This case report presents a patient with central retinal artery occlusion (CRAO) who was successfully treated with hyperbaric oxygen (HBO2) but subsequently suffered a recurrence of his visual loss. Methods: CRAO may be treated successfully with HBO2 if treatment is undertaken promptly after the onset of vision loss. The goal of HBO2 therapy is to oxygenate the ischemic inner retinal layers via diffusion from the hyperoxygenated choroidal circulation until recanalization of the central retinal artery occurs. Results: A 71-year-old man presented with hand motion vision and fundus findings of CRAO in his left eye. Treatment with HBO2 was initiated approximately 9.5 hours after loss of vision. The patient experienced return of vision to a near-normal level during HBO2. His vision loss recurred, however, 15 minutes after the HBO2 session. There was a delay to follow-up HBO2 treatments, and the improvement of vision that resulted from these subsequent HBO2 sessions was much less than that experienced during his initial HBO2 treatment. Conclusion: Recovery of vision during initial HBO2 treatment indicated that this patient's retina had not yet suffered irreversible ischemic damage at that point in time. CRAO patients with a good result from initial HBO2 treatment should be admitted to a stroke center and should have their visual status monitored hourly. Should vision loss recur, aggressive use of intermittent 100% normobaric and hyperbaric oxygen is indicated to preserve retinal function until central retinal artery recanalization occurs. An evidence based management plan for such patients is presented. PMID- 29571240 TI - Re: Evaluation of regulator performance in polar diving.

AB - BACKGROUND: Curcumin (CUR) is a Chinese medicine monomer with antioxidant and anti-inflammatory properties. The aim of this study was to investigate the effects and mechanisms of CUR treatment on ventilator-induced lung injury (VILI) in rats. METHODS: Total 50 SD rats were divided into five groups: sham, VILI, VILI+CUR-50 (CUR 50?mg/kg pretreated intraperitoneal), VILI+CUR-200 (CUR 200?mg/kg pretreated intraperitoneal) and VILI?+?DXM (5?mg/kg pretreated intraperitoneal). The morphology and ultrastructure were observed by microscope and transmission electron microscope. The wet to dry ratio, protein concentration in bronchoalveolar lavage fluid (BALF), evans blue dye (EBD) content, nuclear factor kappa B (NF-?B) activity, myeloperoxidase (MPO), malondialdehyde (MDA), xanthine oxidase (XO) and total antioxidative capacity (TAOC) levels were measured. RESULTS: Histological studies revealed that inflammatory cells infiltration and alveolar edema were significantly severe in VILI as compared to other groups. CUR-200 and DXM treatment reversed lung injury significantly. The wet to dry ratio, protein concentration in BALF, EBD content, MPO activity, tumor necrosis factor (TNF)-? level and NF-?B activity were significantly increased in VILI group as compared to other groups. CUR-200 and DXM treatment significantly suppressed permeability and inflammation induced by ventilation. Furthermore, the significantly higher MDA content in VILI could be markedly decreased by CUR-200 and DXM treatment while the levels of XO and TAOC were markedly recovered only by CUR (200?mg/kg) treatment after VILI. CONCLUSION: CUR could inhibit the inflammatory response and oxidative stress during VILI, which is partly through NF-?B pathway. PMID- 29571244 TI - 1,3,7-Trihydroxyxanthone, derived from Polygalae Radix, a herbal medicine, stimulates the expression of neurotrophic factors in rat astrocyte primary cultures via cAMP- and ERK-dependent pathways. AB - 1,3,7-Trihydroxyxanthone is a compound isolated from Polygalae Radix, a medicinal herb frequently applied for treatment of psychiatric disordres with symptoms of forgetfulness and depression in ancient China. In current research, this compound was applied onto rat astrocyte primary cultures in exploring the action mechanisms of 1,3,7-trihydroxyxanthone on regulating synthesis of neurotrophic factors. It was found that 1,3,7-trihydroxyxanthone could significantly stimulate the expression of NGF and BDNF in dose-dependent manners: the stimulation was both in mRNA and protein levels. Furthermore, 1,3,7-trihydroxyxanthone might fulfill this effect by regulating critical enzymes, such as plasminogen, tissue plasminogen activator, neuroserpin and tissue inhibitor of metalloproteinases in metabolic pathway of neurotrophic factors. Besides, inhibitors of cAMP- and ERK dependent pathways, which implied the possible signaling pathway, could reverse this inducing effect. These results might support the potentiality of 1,3,7 trihydroxyxanthone in drug development in treating psychiatric disorders. PMID- 29571245 TI - Rosemary extract modulates fertility potential, DNA fragmentation, injury, KI67 and P53 alterations induced by etoposide in rat testes. AB - Etoposide is a semi-synthetic compound derived from the plant podophyllum pelltatum and are antineoplastic agents long been used for treatment of human malignancies. The present study was conducted to examine the possible modifying effects of rosemary aqueous extract against sperm abnormalities, testes injury, DNA fragmentation, apoptosis and Ki67 alterations induced by Etoposide in male rats. A total of 50 adult male rats were divided into 5 groups (1st, control; 2nd, rosemary; 3rd, Etoposide; 4th, co-treated Etoposide with rosemary; 5th, post treated Etoposide with rosemary). Sperms counts, motility and viability and KI67 immunoreactivity in testes were significantly decreased while; sperm abnormalities, testicular injury, P53 and DNA damage were a significantly increased in Etoposide group as compared to control group. Co-administration of rosemary with Etoposide improved the sexual toxicity, fertility potential, testicular injury, KI67, P53 and DNA damage induced by Etoposide. Etoposide treatment induced depletion in counts, motility and viability of rat sperms. Etoposide treatment induced testicular DNA damage, injury and decreased in KI67 and P53 expressions. Treatment with rosemary with Etoposide improved these alterations. PMID- 29571246 TI - Hsa_circ_0014717 is downregulated in colorectal cancer and inhibits tumor growth by promoting p16 expression. AB - Circular RNAs (circRNAs) represent a novel class of non-coding RNAs that may regulate gene expression in eukaryotes. Nevertheless, their potential functions in human malignancies are still largely unknown. The aim of this study was to explore the expression of hsa_circ_0014717 in colorectal cancer (CRC) and its role involving in tumor growth. We found that hsa_circ_0014717 was downregulated in CRC tissues and cell lines, and was significantly correlated with TNM stage, distal metastasis and poor overall survival of CRC patients as well. Moreover, our gain-of-function analysis further showed that hsa_circ_0014717 overexpression could significantly suppress CRC cell proliferation and colony formation, as well as induce cell cycle G0/G1 phase arrest in vitro and inhibit xenograft tumor growth in vivo. In addition, hsa_circ_0014717 could upregulate the expression of cell cycle inhibitory protein p16. Besides, p16 knockdown could reverse hsa_circ_0014717 mediated growth inhibition of CRC cells. Taken together, hsa_circ_0014717 acts as a potential tumor suppressor that inhibits CRC growth, partly at least, through upregulating p16 expression. Furthermore, our present study may provide a promising therapeutic target for CRC patients. PMID- 29571247 TI - Comprehensive analysis and experimental verification of LINC01314 as a tumor suppressor in hepatoblastoma. AB - Hepatoblastoma (HB), as a common pediatric liver malignancy, is composed of a variety of subgroups with different clinical outcomes. Long-noncoding RNA (lncRNA) has crucial roles in cancer biology. However, the association between lncRNA and HB has not been fully investigated. In this study, we screened lncRNA expression profiles that were annotated from the GSE75271 dataset. A total of 225 differentially expressed lncRNAs (DELs) were identified based on comparison between three prognostic subgroups, and seven of them (XR_241302, XR_923061, NR_038322, XR_951687, XR_934593, NR_120317 and XR_93406) that exhibited highly predictive accuracies were selected for functional analysis. Weighted gene correlation network analysis (WGCNA) was employed to predict the biological functions of the seven DELs. The Hippo-YAP signaling pathway was predicted to be the most statistically significant predicted pathway associated with the seven DELs. Furthermore, we performed in vitro experiments to validate the biological function of one DEL, NR_120317 (LINC01314). Our results showed decreased proliferation and migration activities of HB cells overexpressing LINC01314. Moreover, mechanistic investigations revealed that LINC01314 overexpression inhibited nuclear translocation of YAP, by inducing MST1 expression and promoting phosphorylation of LATS1 and YAP, consequently downregulating the expression of cell cycle regulatory proteins (MCM7 and cyclin D1). Taken together, our findings provide evidence for LINC01314 as a potential biomarker and anti-cancer therapeutic target in patients with HB. PMID- 29571248 TI - Anti-inflammatory and anti-tumor effects of alpha-l-guluronic acid (G2013) on cancer-related inflammation in a murine breast cancer model. AB - Cancer-related inflammation (CRI) is associated with the malignant progression of several cancer types. Targeting these pathways is a novel promising strategy for cancer prevention and treatment. In this present study, we evaluated the efficacy of ?-l-guluronic acid (ALG), a potent anti-inflammatory agent on breast cancer related inflammation both in vitro and in vivo conditions. Our results indicated that ALG can effectively inhibit the CRI and tumor-promoting mediators (COX-2, MMP2, MMP9, VEGF and proinflammatory cytokines) without direct toxic effects on the cells. Moreover, it was found that, ALG can effectively inhibit the tumor cell adhesion to extracellular matrix, seeding in implantation tissue, reduce accumulation of immunosuppressive and inflammatory cells in tumor-bearing mice. These findings were associated with decreased tumor growth, metastasis, angiogenesis and prolonged mice survival. In conclusion, our data provide a cellular and molecular justification for the use of nonsteroidal anti inflammatory drugs (NSAIDs) in treating cancer and imply the potential anti-tumor activity of ALG therapy via inhibition of CRI. These findings could lead to the establishment of novel NSAID-based cancer therapy in the near future and open a new horizon for cancer treatment.

AB - BACKGROUND: Sepsis is a severe systemic condition caused by an excessive inflammatory response to microbial infections, which often results in high mortality. AIMS: In the present study, the therapeutic effects of thymoquinone were investigated for Gram-negative bacteria-induced sepsis in mice. METHODS: Thymoquinone was administered as 1or 2?mg/kg intraperitoneally 2?h after Escherichia coli (E. coli) challenge. Animal morality was assessed up to 96?h post infection and inflammatory proteins levels were measured 6?h after thymoquinone treatment in various groups using enzyme-linked immunosorbent assay (ELISA) techniques. KEY FINDINGS: The E. coli inoculation markedly increased the level of plasma cytokines, including tumor necrosis factor (TNF)-?, interleukin (IL)-1, IL-2, IL-6 and IL-10. In addition, the levels of selected early sepsis biomarkers such as CRP, VEGF and ESM-1 were amplified in the septic group. Treatment with thymoquinone significantly downregulated the circulating concentrations of the inflammatory proteins (p?70 years than for those <70 years (p < 0.001). The Edmonton Frailty Scale proved to be a reliable tool which may be used in the Polish population. The use of this questionnaire for frailty syndrome may be helpful in everyday clinical practice. PMID- 29571273 TI - Economic burden of skeletal-related events in patients with multiple myeloma: analysis of US commercial claims database. AB - AIMS: To estimate incremental healthcare resource utilization (HRU) and costs associated with skeletal-related events (SREs) secondary to multiple myeloma (MM), and HRU and cost differences in patients with one vs multiple SREs. METHODS: Adults with MM diagnosis between January 1, 2010-December 31, 2014, with benefits coverage >=12 months pre- and >=6 months post-diagnosis were followed to last coverage date or December 31, 2015, excluding patients with prior anti myeloma treatment or cancers. SREs were identified by diagnosis or procedure codes (pathological fracture, spinal cord compression, radiation, or surgery to the bone). SRE patients (index = first post-diagnosis SRE) were propensity score matched 1:1 to patients without SRE (assigned pseudo-index) using baseline characteristics, and >=1 month of continuous enrollment after index/pseudo-index date was required. Per-patient-per year (PPPY) HRU and costs (2016 US$) were determined for inpatient, outpatient, emergency department (ED), and outpatient pharmacy services during follow-up. Wilcoxon signed rank for means and McNemar's tests for proportions were used to assess differences. Negative binomial regression and generalized linear regression analyses estimated differences in HRU and costs, respectively, for the comparison of single vs multiple SREs. RESULTS: Each cohort included 848 patients (mean age = 61 - 62 years, 57% male) with no significant differences in pre-index demographic or clinical characteristics between matched cohorts. Versus non-SRE patients, SRE patients had significantly higher PPPY use (p < .0001) of inpatient hospitalizations, ED visits, outpatient pharmacy, and higher direct medical costs ($188,723 vs $108,160, p < .0001). Adjusted PPPY total costs were $209,820 in patients with multiple SREs; $159,797 in patients with one SRE. LIMITATIONS: SRE misclassification and residual confounding are possible. CONCLUSIONS: Among patients with MM, average annual costs were substantially higher in patients with SRE compared with matched non-SRE patients. The economic burden of SRE increased further with multiple events. PMID- 29571274 TI - Sound therapy and aural rehabilitation for tinnitus: a person centred therapy framework based on an ecological model of tinnitus. AB - PURPOSE: Tinnitus is a common oto-neurological complaint often accompanying hearing loss. In this perspective on rehabilitation we describe a framework for sound therapy and aural rehabilitation of tinnitus based on the ecological model of tinnitus. METHOD: A thematic network analysis-based approach was used to relate aural rehabilitation methods to the ecological model of tinnitus and the client-oriented scale of improvement in tinnitus. RESULTS: Aural rehabilitation methods were mapped to concepts of: (1) Context, (2) presence of sound and (3) reaction to sound. A global theme was: adaptation to sound. The framework is the result of an iterative and cumulative research program exploring tinnitus as the outcome of the relationship between individual psychoacoustics and psychosocial factors including context of perception. CONCLUSIONS: The intent of this framework is to help guide audiologists managing tinnitus. The framework has been useful in our clinic as illustrated by a case study. The benefits of this approach relative to standard care needs to be independently ascertained. Implications for Rehabilitation Tinnitus is a common oto-neurological complaint that when severe can be very disabling. Tinnitus is very heterogeneous as a consequence of this no one treatment is suitable for everyone. The sound therapy and aural rehabilitation for tinnitus framework is designed to assist audiologists in clinical planning that addresses individual needs. The framework is the result of an iterative and cumulative research program exploring tinnitus as the outcome of the relationship between individual psychoacoustics and psychosocial factors including context of perception. PMID- 29571275 TI - Insulin non-persistence among people with type 2 diabetes: how to get your patients to stay on insulin therapy. AB - Continuing use of medication is key to effective treatment and positive health outcomes, particularly in chronic conditions such as diabetes. However, in primary care, non-persistence (i.e. discontinuing or interrupting treatment) with insulin therapy is a common problem among patients with type 2 diabetes. To help primary care physicians manage patients who are non-persistent or likely not to be persistent, this review aimed to provide an overview of modifiable and non modifiable factors associated with insulin non-persistence as well as practical strategies to address them. Data were extracted from published studies evaluating factors associated with non-persistence among patients with type 2 diabetes. A targeted literature review was performed using PubMed to identify recent studies (2000-2016) reporting measures of non-persistence with insulin therapy. Practical strategies to identify and prevent non-persistence were based on the authors' direct experience in primary care. Non-modifiable factors associated with non persistence included gender, age, prior treatments, and cost of therapy. Before/at insulin initiation, modifiable factors included patients' perception of diabetes, preference for oral medication, and concerns/expectations about treatment complexity, inconvenience, or side effects. After initiation, modifiable factors included syringe use, difficulties during the first week of therapy, side effects, and insufficient glycemic control. Open-ended and patient centered questions and a blame-free environment can help physicians identify, prevent, and reduce non-persistence behaviors. Possible questions to start a conversation with patients are provided. Effective physician-patient communication is essential to the management of diabetes. Primary care physicians should be familiar with the most common reasons for insulin non-persistence. PMID- 29571276 TI - Estimating the clinical effectiveness and value-based price range of erenumab for the prevention of migraine in patients with prior treatment failures: a US societal perspective. AB - BACKGROUND: Frequent migraine with four or more headache days per month is a common, disabling neurovascular disease. From a US societal perspective, this analysis models the clinical efficacy and estimates the value-based price (VBP) for erenumab, a fully human monoclonal antibody that inhibits the calcitonin gene related peptide receptor. METHODS: A Markov health state transition model was developed to estimate the incremental costs, quality-adjusted life-years (QALYs), and value-based price range for erenumab in migraine prevention. The model comprises "on preventive treatment", "off preventive treatment", and "death" health states across a 10-year time horizon. The evaluation compared erenumab to no preventive treatment in episodic and chronic migraine patients that have failed at least one preventive therapy. Therapeutic benefits are based on estimated changes in monthly migraine days (MMD) from erenumab pivotal clinical trials and a network meta-analysis of migraine studies. Utilities were estimated using previously published mapping algorithms. A VBP analysis was performed to identify maximum erenumab annual prices at willingness-to-pay (WTP) thresholds of $100,000-$200,000 per QALY. Estimates of VBP under different scenarios such as choice of different comparators, assumptions around inclusion of placebo effect, and exclusion of work productivity losses were also generated. RESULTS: Erenumab resulted in incremental QALYs of 0.185 vs supportive care (SC) and estimated cost offsets due to reduced MMD of $8,482 over 10 years, with an average duration of treatment of 2.01 years. The estimated VBP at WTP thresholds of $100,000-$200,000 for erenumab compared to SC ranged from $14,238-$23,998. VBP estimates including the placebo effect and excluding work productivity ranged from $7,445-$13,809; increasing to $12,151-$18,589 with onabotulinumtoxinA as a comparator in chronic migraine. CONCLUSION: Erenumab is predicted to reduce migraine-related direct and indirect costs, and increase QALYs compared to SC. PMID- 29571277 TI - Tympanic Membrane Derived Stem Cell-Like Cultures for Tissue Regeneration. AB - Epidermal cells with stem cell-like characteristics have been identified in the tympanic membrane (TM) and localized specifically to the umbo and annulus regions. While they have been proposed to play a role in the regeneration of both acute and chronic TM perforations, evidence for the mechanism and regulation of their contribution is not yet described. Indeed, the behavior of these putative stem cells is largely unknown, in part due to a lack of refined methods for efficient cell isolation. In this study, we compared different explant techniques using normal and perforated rat TM tissues and investigated their ex vivo characteristics. TM after perforation in vivo showed increased staining for epidermal stem cell markers integrin beta1 and cytokeratin (CK) 19, and for proliferation Ki-67, indicating activation of the proliferative centers. A mixed population of fibroblasts and epithelial cells were isolated from explant cultures. Excised TM umbo implanted on a culture well insert was the most effective technique. Explants made from perforated TM produced cells before those from unperforated TM. More importantly, the implanted TM umbo organoid was capable of producing cells in a continuous manner, allowing subsequent harvest using trypsin. Primary rat TM epithelial cell cultures positive for pancytokeratin had colony forming activity and could be enriched for CK 19 positive cells that were capable of culture expansion by proliferation and cell migration when subject to a wound assay. Taken together, trauma to the TM activated the proliferative centers and prompted early cell production from TM umbo organoid cultures, which produced TM stem cell-like cultures that proved suitable for tissue engineering of the TM. PMID- 29571278 TI - Localizing Global Medicine: Challenges and Opportunities in Cervical Screening in an Indigenous Community in Ecuador. AB - This participatory research study examines the tensions and opportunities in accessing allopathic medicine, or biomedicine, in the context of a cervical cancer screening program in a rural indigenous community of Northern Ecuador. Focusing on the influence of social networks, the article extends research on "re appropriation" of biomedicine. It does so by recognizing two competing tensions expressed through social interactions: suspicion of allopathic medicine and the desire to maximize one's health. Semistructured individual interviews and focus groups were conducted with 28 women who had previously participated in a government-sponsored cervical screening program. From inductive thematic analysis, the article traces these women's active agency in navigating coherent paths of health. Despite drawing on social networks to overcome formidable challenges, the participants faced enduring system obstacles-the organizational effects of the networks of allopathic medicine. Such obstacles need to be understood to reconcile competing knowledge systems and improve health care access in underresourced communities. PMID- 29571279 TI - Qualitative Assessment of Face Validity and Cross-Cultural Acceptability of the Faces Pain Scale: "Revised" in Cameroon. AB - The Faces Pain Scale-Revised (FPS-R) is a self-report pain scale validated in numerous countries, but not in Cameroon. We postulated that while cultural factors influence pain perception and expression, the FPS-R should remain culturally acceptable for pediatric use. A convenience sample of 36 pediatric patients, aged 4 to 16 years, representing three primary language groups, was enrolled at Mbingo Baptist Hospital (MBH). Pre- and postanalgesia FPS-R scores and vital signs were obtained. Audio-recorded cognitive interviews were performed with each participant. Written questionnaires were also provided to physicians, nurses, and caretakers to further explore cultural perceptions of pain. Four independent reviewers analyzed interview transcripts and questionnaires using inductive reasoning and identified common themes pertaining to gender differences, societal roles, and pain perception. Basic comprehension of the FPS R was present across language groups, vital sign changes corresponded with FPS-R alterations, and the FPS-R appears intuitive for pediatric use.

PMID- 29571281 TI - Use of FTA(r) classic cards for epigenetic analysis of sperm DNA. AB - FTA(r) technologies provide the most reliable method for DNA extraction. Although FTA technologies have been widely used for genetic analysis, there is no literature on their use for epigenetic analysis yet. We present for the first time, a simple method for quantitative methylation assessment based on sperm cells stored on Whatman FTA classic cards. Specifically, elution of seminal DNA from FTA classic cards was successfully tested with an elution buffer and an incubation step in a thermocycler. The eluted DNA was bisulfite converted, amplified by PCR, and a region of interest was pyrosequenced. PMID- 29571282 TI - A triple co-culture method to investigate the effect of macrophages and fibroblasts on myoblast proliferation and migration. AB - The communication between nonmyogenic cells, such as macrophages and fibroblasts, and myoblasts is crucial for successful skeletal muscle repair. In vitro co culture methods can be used to increase our understanding of these cellular interactions; however, current protocols are restricted to two, often physically separate, cell populations. Here, we demonstrate a novel, inexpensive in vitro triple co-culture method that facilitates the co-culture of at least three cell populations with some degree of cell-cell contact. Using this method, we determined the effect of macrophages and fibroblasts on myoblast proliferation and migration. A significant increase in myoblast proliferation and migration was observed following co-culture with either macrophages or fibroblasts. However, triple co-culture of macrophages, fibroblasts, and myoblasts revealed that the presence of macrophages prevented fibroblasts from maintaining this positive effect on myoblast migration. Macrophages, on the other hand, continued to promote myoblast proliferation whether in the presence of fibroblasts or not. Our triple co-culture system highlights the significance of multicellular communication in regulating myoblast proliferation and migration and emphasizes the importance of more complex co-culture systems when investigating myogenesis in vitro. PMID- 29571283 TI - Limitations of methods for measuring the concentration of human genomic DNA and oligonucleotide samples. AB - We compared different methods (absorbance, fluorescent dye-binding, and digital PCR) for measuring the concentrations of human genomic DNA from cultured cells and absorbance measurements of a synthetic DNA oligonucleotide. NIST Standard Reference Material (SRM) 2082, a pathlength absorbance standard, was used to benchmark the absorbance measurements done with microvolume spectrophotometers and a microvolume plate reader. Control absorbance values were measured on a high accuracy spectrophotometer and a NIST calibrated pathlength cuvette. Measurements of the human genomic DNA sample were done with several types of fluorescent dye binding assays using different DNA calibrators. The fluorescent dye binding methods gave different results for genomic DNA depending upon the type of DNA calibrator and the fluorescent dye that was used. The human genomic DNA sample was also characterized by using six different droplet digital PCR assays (amplicons located on different chromosomes) to measure the average copy number. Conversion of the digital PCR data to copy numbers was sensitive to the droplet size used for calculations and conversion to mass concentration was dependent upon the molecular weight of the human genome used for the calculations. The results from the different methods were compared and the caveats for each measurement method were discussed. PMID- 29571284 TI - Detection of nucleic acids with a novel stem-loop primer rolling circle amplification technique. AB - This paper presents a new rolling circle amplification (RCA) technique using stem loop primers (SLP). The technique enables detection of target DNA by either linear or exponential amplification (SLP-lRCA and SLP-eRCA) in both liquid and solid phases. For solid-phase detection, SLP-eRCA detects nucleic acids in four steps: (1) covalently immobilize an array of capture probes (CP) on a solid support; (2) hybridize the CP array with the DNA sample; (3) incubate the CP array with an RCA reaction containing two SLPs; (4) image the CP array. SLP-eRCA detects nucleic acids in liquid phase in one step: a real-time RCA reaction containing the DNA sample and two SLPs. Both liquid- and solid-phase detection methods employ a general rolling circle and an SLP. The other SLP is specific to the target. The technique was verified by detecting synthesized oligonucleotides and six different human papillomaviruses (HPVs), both in liquid phase and on a solid surface. The technique also detected two high-risk HPVs (HPV16 and HPV18) in cervical carcinoma cells (HeLa and SiHa) and clinical samples. This study provides proof-of-concept for the new RCA technique for nucleic acid detection, which overcomes major limitations of current RCA approaches. PMID- 29571285 TI - A multi-trait Bayesian method for mapping QTL and genomic prediction. AB - BACKGROUND: Genomic prediction and quantitative trait loci (QTL) mapping typically analyze one trait at a time but this may ignore the possibility that one polymorphism affects multiple traits. The aim of this study was to develop a multivariate Bayesian approach that could be used for simultaneously elucidating genetic architecture, QTL mapping, and genomic prediction. Our approach uses information from multiple traits to divide markers into 'unassociated' (no association with any trait) and 'associated' (associated with one or more traits). The effect of associated markers is estimated independently for each trait to avoid the assumption that QTL effects follow a multi-variate normal distribution. RESULTS: Using simulated data, our multivariate method (BayesMV) detected a larger number of true QTL (with a posterior probability > 0.9) and increased the accuracy of genomic prediction compared to an equivalent univariate method (BayesR). With real data, accuracies of genomic prediction in validation sets for milk yield traits with high-density genotypes were approximately equal to those from equivalent single-trait methods. BayesMV tended to select a similar number of single nucleotide polymorphisms (SNPs) per trait for genomic prediction compared to BayesR (i.e. those with non-zero effects), but BayesR selected different sets of SNPs for each trait, whereas BayesMV selected a common set of SNPs across traits. Despite these two dramatically different estimates of genetic architecture (i.e. different SNPs affecting each trait vs. pleiotropic SNPs), both models indicated that 3000 to 4000 SNPs are associated with a trait. The BayesMV approach may be advantageous when the aim is to develop a low-density SNP chip that works well for a number of traits. SNPs for milk yield traits identified by BayesMV and BayesR were also found to be associated with detailed milk composition. CONCLUSIONS: The BayesMV method simultaneously estimates the proportion of SNPs that are associated with a combination of traits. When applied to milk production traits, most of the identified SNPs were associated with all three traits (milk, fat and protein yield). BayesMV aims at exploiting pleiotropic QTL and selects a small number of SNPs that could be used to predict multiple traits. PMID- 29571286 TI - Refining a major QTL controlling spotted wilt disease resistance in cultivated peanut (Arachis hypogaea L.) and evaluating its contribution to the resistance variations in peanut germplasm. AB - BACKGROUND: Spotted wilt, caused by tomato spotted wilt virus (TSWV), has been one of major diseases in cultivated peanut grown in the southeastern United States (US) since 1990. Previously a major quantitative trait locus (QTL) controlling spotted wilt disease resistance was mapped to an interval of 2.55 cM genetic distance corresponding to a physical distance of 14.4 Mb on chromosome A01 of peanut by using a segregating F2 population. The current study focuses on refining this major QTL region and evaluating its contributions in the US peanut mini-core germplasm. RESULTS: Two simple sequence repeat (SSR) markers associated with the major QTL were used to genotype F5 individuals, and 25 heterozygous individuals were selected and developed into an F6 segregating population. Based on visual evaluation in the field, a total of 194 susceptible F6 individuals were selected and planted into F7 generation for phenotyping. Nine SSR markers were used to genotype the 194 F6 individuals, and QTL analysis revealed that a confidence interval of 15.2 Mb region had the QTL with 22.8% phenotypic variation explained (PVE). This QTL interval was further genotyped using the Amplicon-seq method. A total of 81 non-redundant single nucleotide polymorphism (SNP) and eight InDel markers were detected. No recombinant was detected among the F6 individuals. Two InDel markers were integrated into the linkage group and helped to refine the confidence interval of this QTL into a 0.8 Mb region. To test the QTL contributes to the resistance variance in US peanut mini-core germplasm, two flanking SSR markers were used to genotype 107 mini-core germplasm accessions. No statistically significant association was observed between the genotype at the QTL region and spotted wilt resistance in the mini-core germplasm, which indicated that the resistance allelic region at this QTL didn't contribute to the resistance variance in the US peanut mini-core germplasm, thus was a unique resistance source. CONCLUSION: A major QTL related to spotted wilt disease resistance in peanut was refined to a 0.8 Mb region on A01 chromosome, which didn't relate to spotted wilt disease resistance in the US peanut mini-core germplasm and might be a unique genetic source. PMID- 29571287 TI - Chronic oxycodone induces axonal degeneration in rat brain. AB - BACKGROUND: Chronic opioid therapy for non-malignant pain conditions has significantly increased over the last 15 years. Recently, the correlation between opioid analgesics and alternations in brain structure, such as leukoencephalopathy, axon demyelination, and white matter lesions, has been demonstrated in patients with a history of long-term use of prescription opioids. The exact mechanisms underlying the neurotoxic effect of opioids on the central nervous system are still not fully understood. We investigated the effect of chronic opioids using an animal model in which female rats were orally gavaged with 15 mg/kg of oxycodone every 24 h for 30 days. In addition we tested oxycodone, morphine and DAMGO in breast adenocarcinoma MCF7 cells, which are known to express the MU-opioid receptor. RESULTS: We observed several changes in the white matter of animals treated with oxycodone: deformation of axonal tracks, reduction in size of axonal fascicles, loss of myelin basic protein and accumulation of amyloid precursor protein beta (beta-APP), suggesting axonal damages by chronic oxycodone. Moreover, we demonstrated activation of pro apoptotic machinery amid suppression of anti-apoptotic signaling in axonal tracks that correlated with activation of biomarkers of the integrated stress response (ISR) in these structures after oxycodone exposure. Using MCF7 cells, we observed induction of the ISR and pro-apoptotic signaling after opioid treatment. We showed that the ISR inhibitor, ISRIB, suppresses opioid-induced Bax and CHOP expression in MCF7 cells. CONCLUSIONS: Altogether, our data suggest that chronic opioid administration may cause neuronal degeneration by activation of the integrated stress response leading to induction of apoptotic signaling in neurons and also by promoting demyelination in CNS. PMID- 29571288 TI - Bone markers and cardiovascular risk in type 2 diabetes patients. AB - BACKGROUND: Vascular calcifications are associated with a three- to fourfold increased risk of cardiovascular disease (CVD) and are highly prevalent in type 2 diabetes patients. Emerging evidence indicates that vascular calcification is a process of active bone formation regulated by stimulators and inhibitors of calcification. Therefore, this study aimed to evaluate whether six bone markers are associated with CVD risk in patients with type 2 diabetes. METHODS: We used data of a case-cohort study, nested in the EPIC-NL cohort, comprising 134 CVD cases and a random subcohort of 218 participants, all with type 2 diabetes at baseline. Six bone markers (osteocalcin, osteopontin, osteonectin, osteoprotegerin, alkaline phosphatase and sclerostin) were measured in baseline plasma samples with multiplex assays and information on CVD events was obtained. The association of bone makers with CVD risk was evaluated using Cox proportional hazard analyses. RESULTS: Higher concentrations of plasma osteopontin were associated (ptrend < 0.01) with an increased CVD risk with a hazard ratio of 2.00 (95%-CI 1.20-3.35) for the highest versus the lowest quartile in a multivariable adjusted model. The other bone markers were not associated with CVD risk. CONCLUSIONS: Higher osteopontin concentrations were associated with an increased CVD risk in type 2 diabetes patients. No consistent associations were found for the other five bone markers and risk of CVD in type 2 diabetes patients. PMID- 29571289 TI - Paclitaxel and curcumin coadministration in novel cationic PEGylated niosomal formulations exhibit enhanced synergistic antitumor efficacy. AB - BACKGROUND: The systemic administration of cytotoxic chemotherapeutic agents for cancer treatment often has toxic side effects, limiting the usage dose. To increase chemotherapeutic efficacy while reducing toxic effects, a rational design for synergy-based drug regimens is essential. This study investigated the augmentation of therapeutic effectiveness with the co-administration of paclitaxel (PTX; an effective chemotherapeutic drug for breast cancer) and curcumin (CUR; a chemosensitizer) in an MCF-7 cell line. RESULTS: We optimized niosome formulations in terms of surfactant and cholesterol content. Afterward, the novel cationic PEGylated niosomal formulations containing Tween-60: cholesterol:DOTAP:DSPE-mPEG (at 59.5:25.5:10:5) were designed and developed to serve as a model for better transfection efficiency and improved stability. The optimum formulations represented potential advantages, including extremely high entrapment efficiency (~ 100% for both therapeutic drug), spherical shape, smooth surface morphology, suitable positive charge (zeta potential ~ + 15 mV for both CUR and PTX), sustained release, small diameter (~ 90 nm for both agents), desired stability, and augmented cellular uptake. Furthermore, the CUR and PTX kinetic release could be adequately fitted to the Higuchi model. A threefold and 3.6-fold reduction in CUR and PTX concentration was measured, respectively, when the CUR and PTX was administered in nano-niosome compared to free CUR and free PTX solutions in MCF-7 cells. When administered in nano-niosome formulations, the combination treatment of CUR and PTX was particularly effective in enhancing the cytotoxicity activity against MCF-7 cells. CONCLUSIONS: Most importantly, CUR and PTX, in both free form and niosomal forms, were determined to be less toxic on MCF-10A human normal cells in comparison to MCF-7 cells. The findings indicate that the combination therapy of PTX with CUR using the novel cationic PEGylated niosome delivery is a promising strategy for more effective breast cancer treatment. PMID- 29571290 TI - Exercise capacity in diabetes mellitus is predicted by activity status and cardiac size rather than cardiac function: a case control study. AB - BACKGROUND: The reasons for reduced exercise capacity in diabetes mellitus (DM) remains incompletely understood, although diastolic dysfunction and diabetic cardiomyopathy are often favored explanations. However, there is a paucity of literature detailing cardiac function and reserve during incremental exercise to evaluate its significance and contribution. We sought to determine associations between comprehensive measures of cardiac function during exercise and maximal oxygen consumption ([Formula: see text]peak), with the hypothesis that the reduction in exercise capacity and cardiac function would be associated with co morbidities and sedentary behavior rather than diabetes itself. METHODS: This case-control study involved 60 subjects [20 with type 1 DM (T1DM), 20 T2DM, and 10 healthy controls age/sex-matched to each diabetes subtype] performing cardiopulmonary exercise testing and bicycle ergometer echocardiography studies. Measures of biventricular function were assessed during incremental exercise to maximal intensity. RESULTS: T2DM subjects were middle-aged (52 +/- 11 years) with a mean T2DM diagnosis of 12 +/- 7 years and modest glycemic control (HbA1c 57 +/- 12 mmol/mol). T1DM participants were younger (35 +/- 8 years), with a 19 +/- 10 year history of T1DM and suboptimal glycemic control (HbA1c 65 +/- 16 mmol/mol). Participants with T2DM were heavier than their controls (body mass index 29.3 +/- 3.4 kg/m2 vs. 24.7 +/- 2.9, P = 0.001), performed less exercise (10 +/- 12 vs. 28 +/- 30 MET hours/week, P = 0.031) and had lower exercise capacity ([Formula: see text]peak = 26 +/- 6 vs. 38 +/- 8 ml/min/kg, P < 0.0001). These differences were not associated with biventricular systolic or left ventricular (LV) diastolic dysfunction at rest or during exercise. There was no difference in weight, exercise participation or [Formula: see text]peak in T1DM subjects as compared to their controls. After accounting for age, sex and body surface area in a multivariate analysis, significant positive predictors of [Formula: see text]peak were cardiac size (LV end-diastolic volume, LVEDV) and estimated MET-hours, while T2DM was a negative predictor. These combined factors accounted for 80% of the variance in [Formula: see text]peak (P < 0.0001). CONCLUSIONS: Exercise capacity is reduced in T2DM subjects relative to matched controls, whereas exercise capacity is preserved in T1DM. There was no evidence of sub-clinical cardiac dysfunction but, rather, there was an association between impaired exercise capacity, small LV volumes and sedentary behavior.

AB - BACKGROUND: The increasing incidence of carbapenem-resistant Enterobacteriaceae (CRE), has resulted in a difficult problem in the current clinical anti-infective treatment. We performed a retrospective analysis of prevalence and treatment for CRE infections patients. METHODS: This study was conducted in three tertiary care hospitals from January 1, 2010 to December 30, 2016. Baseline data, treatment, and outcomes were collected in patients with ventilator-associated bacterial pneumonia (VABP), bacteremia, complicated urinary tract infection (cUTI)/acute pyelonephritis (AP), hospital-acquired bacterial pneumonia (HABP), superficial wound infection (SWI), biliary tract infection (BTI), deep wound infection (DWI) and sterile body fluids infection (SBFI) due to CRE. RESULTS: One hundred twenty four cases of CRE infection were identified: 31 VABP, 22 bacteremia, 18 cUTI/AP, 16 HABP, 16 SWI, 9 BTI, 7 DWI and 5 SBFI. The patient population had significant immunocompromised (33 of 124, 26.6%) and severe sepsis (43 of 124, 34.7%). The most common CRE pathogens were Klebsiella pneumoniae (84 of 124, 67.7%) and Enterobacter cloacae (24 of 124, 19.4%). And the production of IMP-type carbapenemase was the main antibiotic resistance mechanism. The majority of patients to take monotherapy for empiric therapy and dual therapy for direct treatment. Outcomes were universally poor (28-day mortality was 22.6%, 28 of 124) across all sites of infection. CONCLUSIONS: We identified a large number of cases of CRE infection in 7 years from different parts, most of these pathogens have been confirmed to produce IMP-type carbapenemases. The retrospective analysis of cases of such bacterial infections will help to control future infections of these pathogens. Despite the high mortality rate, we still found that the selection of quinolone antibiotics can be effective in the treatment of CRE producing IMP type enzymes. PMID- 29571292 TI - Genetic contexts related to the diffusion of plasmid-mediated CTX-M-55 extended spectrum beta-lactamase isolated from Enterobacteriaceae in China. AB - BACKGROUND: CTX-M-55 extended-spectrum beta-lactamases are being rapidly disseminated and transmitted in clinical practices around the world. The genetic contexts of the transferable plasmid-mediated blaCTX-M-55 gene in Enterobacteriaceae were detected and characterized in this study. METHODS: Isolates were obtained from the First Affiliated Hospital of Zhengzhou University between September 2015 and March 2016. Based on polymerase chain reaction and BLAST analysis, resistance genes and genetic context of the blaCTX-M-55 gene were investigated. Conjugation experiments and multilocus sequence typing were performed to demonstrate plasmid-mediated blaCTX-M-55 transmission. RESULTS: Thirteen blaCTX-M-55-positive isolates of Enterobacteriaceae were obtained. Seven isolates were Escherichia coli, 3 were Klebsiella pneumoniae, 1 was Citrobacter freundii, 1 was Morganella morganii and 1 was Serratia marcescens. The blaCTX-M 55 gene has not previously been identified from C. freundii and M. morganii. Four different blaCTX-M-55 genetic contexts were identified, and all of them harbored ISEcp1 in the region upstream of blaCTX-M-55 (in two cases, ISEcp1 was truncated by IS26, and in one case, it was truncated by IS1294), whereas ORF477 was detected downstream of the blaCTX-M-55 gene from 12 of 13 strains. The novel genetic context of ISEcp1?-blaCTX-M-55-?IS903 was firstly detected the IS903 element which was identified downstream of blaCTX-M-55. A conjugation assay revealed that all blaCTX-M-55 plasmids were quickly and easily transferable to recipient E. coli, which then presented resistance to multiple antibiotics. CONCLUSIONS: Numerous blaCTX-M-55-positive strains were isolated in a short period of 7 months. The findings indicate that blaCTX-M-55 was rapidly disseminated. The genetic context and conjugative transfer found in this study demonstrate that there is active transmission of blaCTX-M-55 among strains of Enterobacteriaceae in China, which could give rise to an urgent global public health threat. PMID- 29571293 TI - Biomarkers of endothelial dysfunction predict sepsis mortality in young infants: a matched case-control study. AB - BACKGROUND: Reducing death due to neonatal sepsis is a global health priority, however there are limited tools to facilitate early recognition and treatment. We hypothesized that measuring circulating biomarkers of endothelial function and integrity (i.e. Angiopoietin-Tie2 axis) would identify young infants with sepsis and predict their clinical outcome. METHODS: We conducted a matched case-control (1:3) study of 98 young infants aged 0-59 days of life presenting to a referral hospital in Bangladesh with suspected sepsis. Plasma levels of Ang-1, Ang-2, sICAM-1, and sVCAM-1 concentrations were measured at admission. The primary outcome was mortality (n = 18); the secondary outcome was bacteremia (n = 10). RESULTS: Ang-2 concentrations at presentation were higher among infants who subsequently died of sepsis compared to survivors (aOR 2.50, p = 0.024). Compared to surviving control infants, the Ang-2:Ang-1 ratio was higher among infants who died (aOR 2.29, p = 0.016) and in infants with bacteremia (aOR 5.72, p = 0.041), and there was an increased odds of death across Ang-2:Ang-1 ratio tertiles (aOR 4.82, p = 0.013). CONCLUSIONS: This study provides new evidence linking the Angiopoietin-Tie2 pathway with mortality and bacteremia in young infants with suspected sepsis. If validated in additional studies, markers of the angiopoietin Tie2 axis may have clinical utility in risk stratification of infants with suspected sepsis. PMID- 29571294 TI - Detection of Neisseria meningitidis in a paediatric patient with septic arthritis using multiplexed diagnostic PCR targeting meningitis/encephalitis (ME). AB - BACKGROUND: Neisseria meningitidis is associated with meningitis and septicemia. Septic meningococcal arthritis is relatively uncommon and its diagnosis associated with clinical and microbiological challenges. Early recognition and treatment is required to prevent joint destruction. PURPOSE: We describe a case of an eleven-year-old boy with septic arthritis and the first reported use of a multiplexed diagnostic PCR test, capable of simultaneous rapid detection of 14 pathogens directly from CSF samples, to determine presence of N. meningitides in a synovial fluid sample. RESULTS: In this case, blood cultures and an aspiration of the joint fluid were negative for microbial growth, but leucocytes were present. Analysis of samples using the multiplexed FilmArray(r) meningitis/encephalitis panel (MEP) proved positive for N. meningitidis. In parallel, samples forwarded to an accredited reference laboratory confirmed the findings by bacterial 16S rRNA gene amplification and sequencing. Subsequent to these results, empiric treatment with intravenous flucloxacillin was discontinued and oral amoxicillin administered for 1 month. The status of the patient improved with etiology-based antimicrobial therapy. CONCLUSIONS: This case demonstrates difficulties associated with clinical and microbiological diagnosis of primary septic meningococcal arthritis. We describe the first successful use of the FilmArray(r) MEP assay in detection of N. meningitidis in that context. PMID- 29571295 TI - Comparison of nephrotoxicity of Colistin with Polymyxin B administered in currently recommended doses: a prospective study. AB - BACKGROUND: The most important concern with polymyxins (Colistin and Polymyxin B) use is nephrotoxicity. There is no prospective data comparing nephrotoxicity of these two drugs, when administered in high doses and as per current recommendations. We conducted a prospective study to compare their trend of nephrotoxicity in our patient population. METHODS: Our study included adult ICU patients who received more than 48 h of Colistin or Polymyxin B and had no confounding factors for nephrotoxicity. Loading and maintenance doses were given as per a uniform protocol. Nephrotoxicity was defined as twofold increase in serum creatinine, or 50% decrease in estimated baseline creatinine clearance. Patients were followed up for 1 week after therapy. Statistical analysis was performed using SPSS version 20.0. RESULTS: 61 patients were included in Colistin group, and 51 patients in Polymyxin B group. Median Colistin dose was 233.3 (IQR 150-300) mg/day and median Polymyxin B dose was 200 (IQR 180-240) mg/day. Median duration of Colistin and Polymyxin B use was 7 (IQR 5-7) days and 7 (IQR 7-9) days respectively. Nephrotoxicity developed in 39.3% patients in Colistin group compared to 11.8% patients in Polymyxin B group. Mean onset of nephrotoxicity was 3.8 +/- 0.8 days with Colistin, and 4.2 +/- 0.7 days with Polymyxin B therapy. In bivariate analysis, Colistin daily dose >= 300 mg was found to be associated with nephrotoxicity. There was no effect of age or BMI on Colistin toxicity. Mean duration of renal failure was 4.9 +/- 3.1 days with Colistin use, and 5.0 +/- 2.4 days with Polymyxin B use. 75% patients in Colistin group and 83.3% patients in Polymyxin B group who developed nephrotoxicity recovered their renal function by 1 week. CONCLUSIONS: Colistin in currently recommended doses is significantly more nephrotoxic than Polymyxin B. Colistin toxicity is dose-dependent, mostly mild to moderate, and is reversible in most cases. PMID- 29571296 TI - YM155 decreases radiation-induced invasion and reverses epithelial-mesenchymal transition by targeting STAT3 in glioblastoma. AB - BACKGROUND: Radiotherapy constitutes a standard arm of therapy in the multimodal treatment of patients with glioblastoma (GBM). Ironically, studies have recently revealed that radiation can augment malignant progression, by promoting migration and invasion, which make the disease especially difficult to cure. Here, we investigated the anticancer effects of YM155, a purported radiosensitizer, in GBM cell lines. METHODS: GBM cell lines U251 and U87 were treated with YM155 to assess cytotoxicity and activity of the molecule in vitro. Nude mice were implanted with cells to generate orthotopic xenografts for in vivo studies. Response of cells to treatment was examined using cell viability, immunofluorescence, wound healing, and the Transwell invasion assay. Molecules potentially mediating response were examined through western blot analysis, phospho-kinase arrays, and qPCR. Cells were transfected with siRNA knockdown and gene expression constructs to identify molecular mediators of response. RESULTS: YM155 reduced viability of U251 and U87 cells and enhanced radiosensitivity through inhibition of homologous recombination. Besides, YM155 decreased invasion caused by radiation and led to expression changes in molecular markers associated with EMT. STAT3 was one of 10 molecules identified on a phosphokinase array exhibiting significant change in phosphorylation under YM155 treatment. Transfection with STAT3 siRNAs or expression constructs demonstrated that EMT changes were achieved by inhibiting the phosphorylation of STAT3 and were survivin-independent. Finally, combining YM155 and radiation in orthotopic xenografts reduced growth and prolonged overall survival of animals. CONCLUSIONS: YM155 decreased radiation-induced invasion in GBM cell lines in vitro and in vivo through inhibition of STAT3.

PMID- 29571298 TI - Toll-like receptor 3 modulates the behavioral effects of cocaine in mice. AB - BACKGROUND: The nucleus accumbens in the midbrain dopamine limbic system plays a key role in cocaine addiction. Toll-like receptors (TLRs) are important pattern recognition receptors (PPRs) in the innate immune system that are also involved in drug dependence; however, the detailed mechanism is largely unknown. METHODS: The present study was designed to investigate the potential role of TLR3 in cocaine addiction. Cocaine-induced conditioned place preference (CPP), locomotor activity, and self-administration were used to determine the effects of TLR3 in the rewarding properties of cocaine. Lentivirus-mediated re-expression of Tlr3 (LV-TLR3) was applied to determine if restoration of TLR3 expression in the NAc is sufficient to restore the cocaine effect in TLR3-/- mice. The protein levels of phospho-NF-kappaB p65, IKKbeta, and p-IkappaBalpha both in the cytoplasm and nucleus of cocaine-induced CPP mice were detected by Western blot. RESULTS: We showed that both TLR3 deficiency and intra-NAc injection of TLR3 inhibitors significantly attenuated cocaine-induced CPP, locomotor activity, and self administration in mice. Importantly, the TLR3-/- mice that received intra-NAc injection of LV-TLR3 displayed significant increases in cocaine-induced CPP and locomotor activity. Finally, we found that TLR3 inhibitor reverted cocaine induced upregulation of phospho-NF-kappaB p65, IKKbeta, and p-IkappaBalpha. CONCLUSIONS: Taken together, our results describe that TLR3 modulates cocaine induced behaviors and provide further evidence supporting a role for central pro inflammatory immune signaling in drug reward. We propose that TLR3 blockade could be a novel approach to treat cocaine addiction. PMID- 29571299 TI - SUPPA2: fast, accurate, and uncertainty-aware differential splicing analysis across multiple conditions. AB - Despite the many approaches to study differential splicing from RNA-seq, many challenges remain unsolved, including computing capacity and sequencing depth requirements. Here we present SUPPA2, a new method that addresses these challenges, and enables streamlined analysis across multiple conditions taking into account biological variability. Using experimental and simulated data, we show that SUPPA2 achieves higher accuracy compared to other methods, especially at low sequencing depth and short read length. We use SUPPA2 to identify novel Transformer2-regulated exons, novel microexons induced during differentiation of bipolar neurons, and novel intron retention events during erythroblast differentiation. PMID- 29571300 TI - Erythroderma and extensive poikiloderma - a rare initial presentation of dermatomyositis: a case report. AB - BACKGROUND: Dermatomyositis is a humoral-mediated inflammatory myopathy with symmetrical proximal muscle weakness and dermatological manifestations such as Gottron's papules, heliotrope rash, periungual abnormalities, and flagellate erythema. Erythroderma is a severe and potentially life-threatening dermatological condition with diffuse erythema and scaling involving more than 90% of the skin surface area. Poikiloderma vasculare atrophicans refers to mottled hyperpigmentation and hypopigmentation of the skin with in-between telangiectases and areas of atrophy and is considered a variant of mycosis fungoides. Poikilodermatomyositis is the term given to the condition with poikiloderma and inflammatory myopathy. Only a few cases are reported on erythroderma in dermatomyositis and poikilodermatomyositis. Erythrodermal pattern of dermatomyositis transforming into poikilodermatomyositis is a recognized rare manifestation of dermatomyositis and we could find only one case report in the literature. CASE PRESENTATION: A 53-year-old Sri Lankan woman presented with intermittent fever of 5 months' duration with erythroderma. Later she developed progressive, symmetrical proximal muscle weakness. Following a short course of small dose steroids, erythroderma settled but changed to extensive poikiloderma involving more than 90% of her skin with her face being relatively spared. She had an early heliotrope rash, shawl sign, and Gottron papules. Electromyography and muscle biopsy were supportive of inflammatory myositis and skin biopsy showed evidence of dermatomyositis. Inflammatory markers and muscle enzymes were also elevated. Autoimmune antibodies and myositis-specific autoantibodies were negative. She was started on orally administered prednisolone 1 mg/kg per day with methotrexate 10 mg once a week and had a good response to treatment with resolution of the skin condition and improvement of muscle power. Imaging studies, endoscopies, and tumor markers did not reveal any malignancy. CONCLUSIONS: This case illustrates a rare presentation of dermatomyositis initially presenting as fever, erythroderma, and proximal muscle weakness and later developing poikiloderma involving more than 90% of the skin. It is important to be aware of this rare presentation to avoid misdiagnosis. With the currently available literature it is not possible to conclude that erythroderma is a bad prognostic factor in dermatomyositis or a predictive factor for a malignancy. Patients have a good response to steroids with a combination of immunosuppressants. PMID- 29571301 TI - Assessment of household ownership of bed nets in areas with and without artemisinin resistance containment measures in Myanmar. AB - BACKGROUND: Myanmar lies in the Greater Mekong Subregion where there is artemisinin-resistant Plasmodium falciparum malaria. As the artemisinin compound is the pillar of effective antimalarial therapies, containing the spread of artemisinin resistance is a national and global priority. The use of insecticide treated bed nets/long-lasting insecticidal nets (ITNs/LLINs) is the key intervention for ensuring the reduction of malaria transmission and the spread of resistant strains, and for eventually eliminating malaria. This study aimed at assessing household ownership of, access to, and utilization of bed nets in areas of Myanmar with and without artemisinin resistance containment measures. METHODS: Secondary data from a nationwide community-based malaria survey conducted by the National Malaria Control Program in 2014 were analyzed. Based on evidence of artemisinin resistance, Myanmar was divided into tiers 1, 2, and 3: townships in tiers 1 and 2 were aggregated as the Myanmar Artemisinin Resistance Containment (MARC) areas and were compared with tier 3 townships, which were defined as non MARC areas. The chi-square test was used to compare groups, and the level of significance was set at P <= 0.05. RESULTS: Of the 6328 households assessed, 97.2% in both MARC and non-MARC areas had at least one bed net (any type), but only 63% of households had ITNs/LLINs. Only 44% of households in MARC areas and 24% in non-MARC areas had adequate numbers of ITNs/LLINs (one ITN/LLIN per two persons, P < 0.001). Nearly 44% of household members had access to ITNs/LLINs. Regarding the utilization of ITNs/LLINs, 45% of household members used them in MARC areas and 36% used them in non-MARC areas (P < 0.001, desired target = 100%). Utilization of ITNs/LLINs among children aged below five years and pregnant women (high malaria risk groups) was low, at 44% and 42%, respectively. CONCLUSIONS: This study highlights the nationwide shortfalls in the ownership of, access to, and utilization of ITNs/LLINs in Myanmar, which is of particular concern in terms of containing the spread of artemisinin resistance. It highlights the need for priority attention to be paid and mobilization of resources in order to improve bed net coverage and utilization through bed net distribution and/or social marketing, information dissemination, and awareness raising. PMID- 29571302 TI - High-Performance Thin-Layer Chromatography Coupled with Electrospray Ionization Tandem Mass Spectrometry for Identifying Neutral Lipids and Sphingolipids in Complex Samples. AB - High-performance thin-layer chromatography was directly combined with electrospray mass spectrometry (ESI-MS) for structural identification issues below the level of lipid classes in complex samples through a portable, automated, elution-based interface. For samples as diverse as biodiesel and human plasma, separation conditions using Automated Multiple Development were selected in each case to provide lipid classes as zones narrow enough to ensure a direct transfer of them to ESI-MS. The respective zone of interest can be selected at will. ESI+ spectra of neutral lipids and sphingolipids showed sodium adducts when recorded from the plate. By using the described technique and ion-trap technology, the respective sodium adducts were fragmented. Sodium remained as the charge of the fragment ions and, thus, was useful for their structural identification through MSn. In this way, composition profiles of each class by ESI+-MS, and further identification of individual lipids and the molecular species belonging to each of them, were obtained by MS/MS and/or high-resolution MS. Thus, mono and diacylglycerides in ESI+ and fatty acids (in ESI-) were identified as low-concentration impurities in a fatty acid methyl ester-based biodiesel sample. Likewise, molecular species of sphingomyelins and globotriaosylceramides were unequivocally identified in human plasma samples. PMID- 29571303 TI - Development and Validation of a Surface Plasmon Resonance Biosensor for Specific Detection of Porcine Serum Albumin in Food. AB - Food allergies are a potential food safety and public health concern worldwide. To assure the safety of people who experience allergic reactions, it is necessary to establish effective and reliable methods for rapid detection of food allergens. This paper reports an innovative method for the rapid detection and analysis of porcine serum albumin (PSA), known as a major allergen in pork, based on a surface plasmon resonance (SPR) biosensor. The antibodies known to have a high bioactivity against PSA were verified by competitive indirect-ELISA and then immobilized on the SPR sensor surface, thus allowing them to capture PSA. The developed SPR demonstrated a linear range from 1.0 to 450 ng/mL for the measurement of PSA with a detection limit of 19.81 ng/mL. Within-day RSD (1.97 4.02%) and between-day RSD (1.88-4.15%) were no more than 5%. The SPR was evaluated for analysis of six commercial food samples and showed almost perfect agreement between the results obtained by ELISA test kits without significant differences (P > 0.05). Therefore, this assay permits accurate, specific, and sensitive detection of PSA in pork and pork products. PMID- 29571304 TI - Ultrasound-Assisted Emulsification Microextraction in an Online System for Determination of Cadmium in Water and Tea Samples. AB - In this work, a method using ultrasound-assisted emulsification microextraction (USAEME) without the use of ligands in an online system for preconcentration and determination of cadmium was developed. The method was based on the preconcentration of cadmium by USAEME, employing trichloroethylene as the extraction solvent, and subsequent retention of the rich phase in a mini-column packed with silica gel. The extracted metal was determined by flame atomic absorption spectrometry. The parameters that affect the extraction of cadmium were optimized using the univariate method. Under optimized conditions, the method presented a limit of detection of 0.17 MUg/L, a limit of quantification of 0.57 MUg/L, an enrichment factor of 56, and a consumptive index of 0.18 mL/min. The accuracy of the method was tested by analyzing the certified reference material, National Institute of Standards and Technology (NIST) 1573 (tomato leaves). The determination of Cd in water (drinking water, bottled water, river water, and seawater) and tea (black and green tea) samples was also performed using the proposed method. The method is simple, efficient, and eco-friendly because it requires low consumption of an organic solvent. PMID- 29571305 TI - Determination of Biogenic Amines in Cheese by Ion Chromatography with Tandem Mass Spectrometry Detection. AB - A new method for determination of underivatized biogenic amines in cheese based on ion exchange chromatography coupled with tandem mass spectrometric detection was proposed. The method was applied to the analysis of 10 biogenic amines (trimethylamine, putrescine, cadaverine, histamine, 2-phenylethylamine, spermine, spermidine, tryptamine, agmatine, and tyramine) in different types of cheese. The amines were extracted only with water without any additional derivatization step or sample cleanup. This is a great advantage in terms of simplicity of sample pretreatment procedure compared with other currently existing methods in the literature. Biogenic amines were separated using cation exchange column, under gradient elution conditions by mixing formic acid (1.00 M) and deionized water. Detection was achieved using tandem MS/MS, with the instrument set into multiple reaction monitoring mode to ensure high specificity. The detection and quantification limits were in the ranges of 12-46 MUg/L and 40-153 MUg/L, respectively. The exceptions were spermidine and spermine, with detection limits of 0.8 and 5.4 mg/L, respectively. The linearity for most of the biogenic amines was from 10 MUg/L up to 10 mg/L. The best recoveries were observed for trimethylamine, tyramine, and cadaverine, and were 89, 94, and 102%, respectively. The results showed that this method can be used for routine determination of biogenic amines in different types of cheeses as well other food matrices. It must be stressed that the proposed method is capable of determining 10 biogenic amines, including tyramine, which is reported to cause food intoxication commonly associated with cheeses.

AB - The third most common form of limb-girdle muscular dystrophies is caused by mutations of the Fukutin-related protein (FKRP) gene, with no effective therapy available. Selective estrogen receptor modulators, tamoxifen and raloxifene, have been widely used for human conditions for their anti-inflammatory, antifibrosis, prevention of bone loss, and muscle building effects (essential features for muscular dystrophy therapies). We evaluated therapeutic values of tamoxifen and raloxifene in FKRPP448L mutant mouse with severe dystrophic phenotype. The mice were treated with the drugs for 1 year through daily gavage. We demonstrate that tamoxifen and raloxifene significantly ameliorated the disease progression. The improvement includes increase in grip force production, extended running time and distance in treadmill test, and enhancement in cardiac and respiratory functions. Significant reduction in muscle pathology includes diminished fibrosis and fiber degeneration. Tamoxifen and raloxifene also significantly mitigated bone loss. Tamoxifen, but not raloxifene, caused severe adverse effects on male reproductive organs. The results demonstrate that tamoxifen and raloxifene hold significant potential for treating FKRP-related muscular dystrophy and probably other muscular dystrophies. Sex-related differential effects of the drugs call for a careful consideration for the drug and dosage selection in male and female patient populations.

AB - The Fuhrman and World Health Organization/International Society of Urological Pathology (WHO/ISUP) grading systems are widely used to predict survival for patients with conventional renal cell carcinoma. To determine the validity of nuclear grading systems (both the Fuhrman and the WHO/ISUP) and the individual components of the Fuhrman grading system in predicting the prognosis of Xp11.2 translocation renal cell carcinoma (Xp11.2 tRCC), we identified and followed up 47 patients with Xp11.2 tRCC in our center from January 2007 to June 2017. The Fuhrman and WHO/ISUP grading was reassigned by two pathologists. Nuclear size and shape were determined for each case based on the greatest degree of nuclear pleomorphism using image analysis software. Univariate and multivariate analyses were performed to evaluate the capacity of the grading systems and nuclear parameters to predict overall survival and progression-free survival. On univariate Cox regression analysis, the parameters of nuclear size were associated significantly with overall survival and progression-free survival, whereas the grading systems and the parameters of nuclear shape failed to reach a significant correlation. On multivariate analysis, however, none of the parameters was associated independently with survival. Our findings indicate that neither the Fuhrman nor the WHO/ISUP grading system is applicable to Xp11.2 tRCC. The assessment of nuclear size instead may be novel outcome predictors for patients with Xp11.2 tRCC.

AB - Resolvin conjugates in tissue regeneration (RCTRs) are new chemical signals that accelerate resolution of inflammation, infection, and tissue regeneration. Herein, using liquid chromatography-tandem mass spectrometry-based metabololipidomics, we identified RCTRs in human spleen, lymph node, bone marrow, and brain. In human spleen incubated with Staphylococcus aureus, endogenous RCTRs were increased along with conversion of deuterium-labeled docosahexaenoic acid, conferring pathway activation. Physical and biological properties of endogenous RCTRs were matched with those prepared by total organic synthesis. The complete stereochemical assignment of bioactive RCTR1 is 8R-glutathionyl-7S,17S-dihydroxy 4Z,9E,11E,13Z,15E,19Z-docosahexaenoic acid, RCTR2 is 8R-cysteinylglycinyl-7S,17S dihydroxy-4Z,9E,11E,13Z,15E,19Z-docosahexaenoic acid, and RCTR3 is 8R-cysteinyl 7S,17S-dihydroxy-4Z,9E,11E,13Z,15E,19Z-docosahexaenoic acid. These stereochemically defined RCTRs stimulated human macrophage phagocytosis, efferocytosis, and planaria tissue generation. Proteome profiling demonstrated that RCTRs regulated both proinflammatory and anti-inflammatory cytokines with human macrophages. In microfluidic chambers, the three RCTRs limited human polymorphonuclear cell migration. In hind-limb ischemia-reperfusion-initiated organ injury, both RCTR2 and RCTR3 reduced polymorphonuclear cell infiltration into lungs. In infectious peritonitis, RCTR1 shortened the resolution intervals. Each RCTR (1 nmol/L) accelerated planaria tissue regeneration by approximately 0.5 days, with direct comparison to both maresin and protectin CTRs. Together, these results identify a new bioactive RCTR (ie, RCTR3) in human tissues and establish the complete stereochemistry and rank-order potencies of three RCTRs in vivo. Moreover, RCTR1, RCTR2, and RCTR3 each exert potent anti-inflammatory and proresolving actions with human leukocytes. PMID- 29571329 TI - Invited Commentary. PMID- 29571328 TI - Invited Commentary. PMID- 29571330 TI - Chest Wall Mechanics In Vivo With a New Custom-Made Three-Dimensional-Printed Sternal Prosthesis. AB - PURPOSE: Reconstruction after sternal resection is performed according to surgeon intuition; physiologic evidence for selection of prostheses is lacking. We present our experience of the in vivo function of a novel device for sternal reconstruction. DESCRIPTION: A three-dimensional-printed titanium and porous polyethylene sternal prosthesis was made according to the patient's computed tomographic scan. The titanium arms slot over adjacent ribs and are fixed in place with screws. The porous element allows ingrowth of native tissue while preventing lung herniation around the narrow titanium bars. EVALUATION: We performed optoelectronic plethysmography to assess the physiologic function of the device compared with a muscle flap reconstruction. Asynchronous and paradoxical movements of the thoracoabdominal surface were apparent with the muscle flap reconstruction but not with the new device. Considerably higher tidal volumes and a lower respiratory rate achieved the same minute volume with the new device compared with the muscle flap. CONCLUSIONS: Rigid sternal reconstruction with a three-dimensional-printed prosthesis demonstrated superior respiratory mechanics compared with reconstruction with an autologous muscle flap.

AB - Donor T cells after allogeneic hematopoietic cell transplantation can give rise to the graft-versus-tumor (GVT) effect in hematologic malignancies. GVT effect has been reported previously to cause regression of some solid tumors. However, none have reported a documented case of GVT effect leading to complete resolution of adenocarcinoma of the lung. Here, we present the case of complete regression of a pathologically proven adenocarcinoma of the lung in a patient undergoing myeloablative-matched unrelated donor peripheral blood stem cell transplantation for the treatment of acute myelogenous leukemia.

AB - An infant unable to be weaned from cardiopulmonary bypass after orthotopic heart transplantation was cannulated for extracorporeal membrane oxygenation. During the next 3 days, allograft failure and intracardiac thrombosis necessitated cardiectomy. To provide acute mechanical circulatory support, artificial atrial chambers were constructed with Gore-Tex conduits and PediMag centrifugal pumps were connected to each by Berlin Heart EXCOR cannulae. The PediMag pumps were subsequently exchanged for 10-mL Berlin Heart EXCOR pumps. After 60 days of support by total artificial heart, the patient was bridged successfully to a second heart transplant.

AB - Spontaneous pneumomediastinum is the presence of interstitial air in the mediastinal structures without an apparent cause. Pneumorrhachis is defined as the presence of air in the spinal canal. Concurrent pneumorrhachis is an extremely rare epiphenomenon of spontaneous pneumomediastinum without pneumothorax. Diagnosis is confirmed by radiologic imaging of the chest. Spontaneous pneumomediastinum and pneumorrhachis usually resolve with conservative therapy such as bed rest, analgesic agents, and supplemental oxygen. A 20-year-old male patient presented with recurrent spontaneous pneumomediastinum with concurrent pneumorrhachis with a gap of 1 year between the two episodes. Pneumomediastinum and pneumorrhachis resolved with conservative management in both episodes.

AB - Although several studies have evaluated the local control and survival outcomes in patients undergoing stereotactic body radiotherapy (SBRT) for pulmonary oligometastases, little data are available on the management of local relapse. Here, we present 3 patients who underwent lobectomy and mediastinal lymph node dissection as salvage pulmonary metastasectomy for local relapse after SBRT. The postoperative course has been uneventful for all 3 patients, with no evidence of disease at 40, 51, and 6 months from the salvage metastasectomy. Our experience suggests that salvage pulmonary metastasectomy may be associated with local control and long-term survival in carefully selected patients.

AB - Congenital mitral valve disease is a real challenge in infants and small children. The implantation of expandable stented valves in mitral position has become one of the options of choice in consideration of their acceptable short term expandable durability and subsequent feasibility of balloon expansion of these devices. We report the first case of a surgical Melody valve-in-valve procedure for early Melody valve degeneration in the mitral position. The result was good, and the procedure safe, rapid, and without an increased risk when a mechanical valve implantation will be necessary. PMID- 29571349 TI - Two Cases of Surgical Management of Supravalvular Aortic Stenosis in Familial Hypercholesterolemia. AB - Homozygous familial hypercholesterolemia is a rare autosomal dominant disorder caused by gene mutations of the low-density lipoprotein receptor, generally characterized by three major signs-hyper low-density lipoprotein cholesterolemia, tendon/skin xanthomas, and premature atherosclerosis disease-beginning in childhood and including supravalvular aortic stenosis. To the best of our knowledge, only a few successful surgical cases for supravalvular aortic stenosis in these patients have been reported. We report two cases of homozygous familial hypercholesterolemia with severe supravalvular aortic stenosis and coronary artery disease associated with very small aortic root, managed by aortic root replacement concomitant with coronary artery bypass graft surgery, which resulted in excellent postoperative outcomes.

It is a morbid condition associated with pain and sternal instability. We present two challenging cases of sterile sternotomy nonunion after cardiac operations that were treated successfully with novel methods adopted from the Elastic Stable Chest Repair for complex pectus deformity repair, using transverse costal to costal external cortical plates and bicortical screws, after debridement, autologous bone grafting and double loop wire sternal approximation.

AB - A monitoring program was carried out in autumn 2015 along the Mediterranean coast of Morocco, at sites including urban, village and remote/rural beaches. Artificial Polymer Materials (APM) represented 70.64% of all collected items and included plastic (16 categories), foamed plastic (3) and other APM materials (2). Plastic items represented the dominant debris with 5356 items, i.e. 94.53% of all APM debris, foamed plastics presented 191 items (i.e. 3.37%) and other APM summed 119 items, i.e. 2.1% of all APM. Urban areas presented 49.63% of all APM recollected items with cigarette butts representing 32% of total APM items. Village areas presented 40.43% of total APM recollected items with cigarette butts representing 14.1%. Remote and rural beaches recorded 9.94% of total APM items and no cigarette butts were observed. Despite the efforts of local administrations, which introduced litter bins and enforced mechanical and manual cleaning operations, debris were essentially related to beachgoers. PMID- 29571353 TI - Aerosol concentrations and atmospheric dry deposition fluxes of nutrients over Daya Bay, South China Sea. AB - Based on one and a half years of observations (September 2015 to March 2017) in Daya Bay, we analysed the nutrient concentrations in aerosols and calculated dry deposition fluxes of nutrients. DON was the dominant species of TDN in aerosol particles, accounting for 63.3%. The mean values of DIP, DOP and DSi were 0.78, 0.61 and 2.6 nmol.m-3, respectively. The mean fluxes of nutrients (TDN, TDP and DSi) from dry deposition during the field observation were 2150, 7.4 and 28.2 MUmol.m-2.month-1, respectively. The fluxes of nitrogen species show a seasonal pattern with higher input in spring and winter. The dry deposition of nutrients accounted for approximately 20% of the total deposition budget. The molar ratios of DIN/DIP in the dry deposition (mean value 167) suggest that atmospheric dry deposition of nutrients may increase the risk of the unbalanced nutrient condition in the seawater column of Daya Bay.

AB - As a result of the 2011 Great East Japan earthquake, about 11,000kL of fuel oil was spilled into Kesennuma Bay, Miyagi Prefecture. This oil either accumulated in seabed sediments or was burned in a marine fire on the sea surface. We investigated spatial and temporal variations in the concentrations of oil and hydrocarbons. The maximum concentrations of n-hexane extract (NHE), total petroleum hydrocarbon (TPH), and polycyclic aromatic hydrocarbons (PAHs) in the sediments in 2012 were 8000, 1200, and 16.2mg/kg (DW), respectively. NHE and TPH concentrations were high in the inner and west bay, and PAHs concentrations were high in the east bay. NHE and PAH concentrations didn't change; however, TPH concentrations decreased significantly with time. The total NHE in the sediment across the whole bay was estimated at 1685kL and there was still about 13% of the original amount in the sediment in December 2014. PMID- 29571355 TI - Composition and abundance of marine debris stranded on the beaches of Sri Lanka: Results from the first island-wide survey. AB - This study provides the first assessment of marine debris washed ashore on 22 beaches along the coast of Sri Lanka. There was an average of 4.1 large (>25 mm) and 158 small (5-25 mm) pieces of debris per square meter of beach. Classified by use, packaging material (55%) dominated the debris, followed by consumer products (25%) and fishing gear (20%). In terms of materials, plastic was the greatest contributor (93%) to marine debris. Beaches near a river mouth or city and those with a barrier had greater debris accumulations. The east coast had significantly greater small debris density, possibly due to strong northeastern monsoon currents. Large spatial heterogeneity was observed in the amount of debris. Long term monitoring is imperative to better understand the temporal changes in, and the pathways and possible management of, marine debris. PMID- 29571356 TI - Contamination level, chemical fraction and ecological risk of heavy metals in sediments from Daya Bay, South China Sea. AB - Contamination level, chemical fraction and ecological risk of heavy metals in sediments from Daya Bay (DYB) were conducted in this study. The results revealed that the concentration of Cr, Cu, Zn, As, Cd and Pb in sediments were in the range of 36.38-90.33, 9.54-61.32, 33.54-207.33, 7.80-18.43, 0.13-0.43 and 15.89 30.01 mg kg-1, respectively, with bioavailable fractions of 13.29, 54.16, 47.60, 32.74, 68.14, 26.59%, respectively. A modified potential ecological risk index (MRI) was used for the ecological risk assessment, with ecological risk contribution ratios of 75.73, 14.29, 5.47, 1.74, 1.57 and 1.21% for Cd, As, Cu, Cr, Pb and Zn, respectively. The main contaminants were Cd and As, with their ecological risks "High" and "Moderate" levels, and their enrichment degrees "Moderately Severe" and "Moderate", respectively. The multivariate statistical analysis suggested that the various anthropogenic activities along the bay might contribute mainly to the heavy metals contamination in DYB.

AB - 3D coupled modeling approach is used for the PCB dispersion assessment in the Gulf of Lion and its transfer to zooplankton via biogeochemical processes. PCB budgets and fluxes between the different species of PCB: dissolved, particulate, biosorbed on plankton, assimilated by zooplankton, which are governed by different processes: adsorption/desorption, bacteria and plankton mortality, zooplankton excretion, grazing, mineralization, volatilization have been estimated. Model outputs were compared with the available in situ data. It was found that the Rhone River outflows play an important role in the organism contamination in the coastal zone, whereas the atmospheric depositions are rather more important in the offshore zones. The transfer of the available contaminant to bacteria and phytoplankton species is mainly related to the biomass present in the water column. Absorption fluxes (grazing) to zooplankton are rather higher than the passive sorption fluxes, which are themselves also linked to the sorption coefficient. PMID- 29571358 TI - Changes in mercury exposure of marine birds breeding in the Gulf of Maine, 2008 2013. AB - Mercury is a potent contaminant that can disrupt an organism's behavior and physiology, ultimately affecting reproductive success. Over the last 100 years, environmental deposition of anthropogenic sourced mercury has increased globally, particularly in the U.S. Northeast region. Marine birds are considered effective bioindicators of ecosystem health, including persistent marine contaminants. Goodale et al. (2008) found that mercury exposure exceeded adverse effects levels in some marine bird species breeding across the Gulf of Maine. We re-examined mercury contamination in four species identified as effective bioindicators. Compared with the previous sampling effort, inshore-feeding species showed significant increases in mercury exposure, while one pelagic-feeding species remained stable. This suggests that a major shift may have occurred in methylmercury availability in inshore waters of the Gulf of Maine. Understanding environmental mercury trends in the Gulf of Maine, and its significance to marine birds and other taxa will require a dedicated, standardized, long-term monitoring scheme. PMID- 29571359 TI - Collected marine litter - A growing waste challenge. AB - Marine litter, in particular plastic debris, poses a serious threat to marine life, human health and the economy. In order to reduce its impact, marine litter collections such as beach clean-ups are frequently conducted. This paper presents a systematic review of temporal developments, geographical distribution, quantities and waste treatment pathways of collected marine litter. Results from over 130 studies and projects highlight the worldwide increase in collection efforts. Many of these are in wealthy countries that do not primarily contribute to the problem. Over 250 thousand tonnes, have already been removed, but there is little or no information available regarding how this waste is treated or used post collection. This paper highlights the need for a whole-system quantitative assessment for the collection and waste treatment of marine litter, and identifies the challenges associated with utilising this waste in the future. PMID- 29571360 TI - First assessment of the effectiveness of the international convention on the control of harmful anti-fouling systems on ships in Tunisia using imposex in Hexaplex trunculus as biomarker. AB - The global ban on the use of tributyltin (TBT) forced in September 2008 was ratified in Tunisia as late as June 2011. In this context, the present study aims to highlight the consequences of TBT contamination by monitoring 22 Tunisian sites before (2007) and after the ban (2012 and 2016) using as biomarker the occurrence of imposex in Hexaplex trunculus. From 2004 to 2016, complete recovery from imposex was reported in 11 sites. All average imposex indices calculated for each sampling year also decreased: imposex incidence from 61 to 27%, VDSI from 2 to 0.7, and RPLI from 15.7 to 1.6%. Ecological Quality Ratios (EQR) revealed that the sampling sites are in moderate to good ecological status. Overall, the present study confirms the effectiveness of the enacted legislation in reducing the impact of TBT pollution along the Tunisian coast. PMID- 29571361 TI - Macrophytes as bioindicators of heavy metal pollution in estuarine and coastal environments. AB - The Derwent estuary, in Tasmania (Australia), is highly contaminated with heavy metals with significant levels in both sediments and benthic fauna. However, little is known about metal content in benthic primary producers. We characterized metal content (Arsenic, Cadmium, Copper, Lead, Selenium and Zinc) in twelve species of macrophyte, including red, green, and brown algae, and seagrasses, from the Derwent. The metals, arsenic, copper, lead, and Zinc were detected in all of the macrophytes assessed, but the levels differed between species. Seagrasses accumulated the highest concentrations of all metals; with Zn levels being particularly high in the seagrass Ruppia megacarpa (from the upper Estuary) and Pb was detected in Zostera muelleri (from the middle estuary). Ulva australis was ubiquitous throughout the middle-lower estuary and accumulated Zn in relatively high concentrations. The findings suggest that analysis of multiple species may be necessary for a comprehensive understanding of estuary-wide metal pollution. PMID- 29571362 TI - Beach litter and woody-debris colonizers on the Atlantico department Caribbean coastline, Colombia. AB - Some marine invertebrates can inhabit floating substrates, and raft over long distances, becoming a significant environmental problem in terms of alien species and habitat disruption. On the Atlantico Department beaches (Colombia) woody debris and plastic litter dominate (86%) the types of refuse on the beaches with their densities ranging from 0.82-1.72 items m-1. Such litter and woody debris generate the optimal conditions for floating colonizers. In this work, 26 beaches were surveyed, and 16 of them (62%) were found to have marine fauna using litter and woody debris as a substrate for potential rafting and dispersal. Serpulidae polychaete tubes, goose barnacles Lepas (Anatifa) anserifera Linnaeus, 1767, and the bryozoans Arbopercula tenella (Hincks, 1880), Arbopercula angulata (Levinsen, 1909), plus three unidentified species were found colonizing woody debris, seeds, plastic and glass bottles. These findings of woody debris and litter facilitating the arrival and dispersal of non-native species on this coast, demonstrate that preventive management of such refuse in coastal habitats goes beyond simply preserving coastal esthetics. PMID- 29571364 TI - Biodegradation of hexadecane using sediments from rivers and lagoons of the Southern Gulf of Mexico. AB - The Southern Gulf of Mexico is an area highly impacted by crude oil extraction, refining activities and the presence of natural petroleum seepage. Oceanic currents in the Gulf of Mexico continually facilitate the transport of hydrocarbons to lagoons and rivers. This research evaluated hexadecane (HXD) degradation in marine sediment samples from lagoons and rivers that are fed by the Southern Gulf of Mexico, specifically six samples from rivers, three samples from lagoons, and one sample from a marine outfall. The highest rates of biodegradation were observed in sediments from the mouths of the Gonzalez River and the Champoton Lagoon. The lowest consumption rate was found in sediment from the mouth of the Coatzacoalcos River. With regards to the Ostion Lagoon and the Grijalva River, there was a low rate of consumption, but a high efficiency of degradation which took place at the end of the experiments. No correlation was found between the consumption rate and the environmental physicochemical parameters. PMID- 29571363 TI - Risk assessment of some heavy metals in mussels (Mytilus galloprovincialis) and veined rapa whelks (Rapana venosa) for human health. AB - The purpose of the present study was to analyze the concentrations of lead, cadmium and mercury in mussels (Mytilus galloprovincialis) and veined rapa whelks (Rapana venosa) caught in the Varna Bay of Black Sea and to evaluate the risk for human health from the presence of the three heavy metals. The highest average concentrations in mussels were those of cadmium (0.280 mg/kg), followed by lead (0.251 mg/kg) and mercury (0.017 mg/kg). Veined rapa whelks also showed highest levels of cadmium (1.113 mg/kg), followed by lead (0.045 mg/kg) and mercury (0.034 mg/kg). EDI values for adults consuming mussels and veined rapa whelks were below the published RfDo and PTWI values. All THQ and HI values were below 1. The consumption of M. galloprovincialis and R. venosa caught in the Varna Bay, Black Sea, did not pose any risk for the health of adult people as lead, cadmium and mercury were concerned. PMID- 29571365 TI - Organochlorine pesticide accumulation in seabirds and marine mammals from the Northwest Pacific. AB - Bioaccumulation of organochlorine pesticides by marine organisms is one of the methods of environmental quality. Concentrations of organochlorine pesticides (HCH isomers (alpha-, beta-, gamma-HCH), p,p'-DDT and its metabolites (p,p'-DDD, p,p'-DDE)) in samples of seabirds (Northern fulmar Fulmarus glacialis, Crested auklet Aethia cristatella, Auklet-crumb Aethia pusilla, Pacific gull Larus schistisagus, and Gray petrel Oceanodroma furcate) and marine mammals (Gray whales Eschrichtius robustus and Pacific walrus Odobenus rosmarus divergens) were measured by a GC-MS. The total concentration of OCPs in mammals was higher than in seabirds. Environmental biomonitoring with the use of seabirds and marine mammals, as a long-lived species, is used for global monitoring, since bioaccumulation in these organisms occurs throughout life. The environmental assessment of the Northwest Pacific marine ecosystems revealed that the levels of OCP contamination in this area are similar to the other subarctic regions of the World Ocean. PMID- 29571366 TI - Ecophysiological and metabolic responses to interactive exposure to nutrients and copper excess in the brown macroalga Cystoseira tamariscifolia. AB - Global scenarios evidence that contamination due to anthropogenic activities occur at different spatial-temporal scales, being important stressors: eutrophication, due to increased nutrient inputs; and metal pollution, mostly derived from industrial activities. In this study, we investigated ecophysiological and metabolic responses to copper and nutrient excess in the brown macroalga Cystoseira tamariscifolia. Whole plants were incubated in an indoor system under control conditions, two levels of nominal copper (0.5 and 2.0MUM), and two levels of nutrient supply for two weeks. Maximal quantum yield (Fv/Fm) and maximal electron transport rate (ETRmax) increased under copper exposure. Photosynthetic pigments and phenolic compounds (PC) increased under the highest copper levels. The intra-cellular copper content increased under high copper exposure in both nutrient conditions. C. tamariscifolia from the Atlantic displayed efficient metal exclusion mechanisms, since most of the total copper accumulated by the cell was bound to the cell wall. PMID- 29571367 TI - Microplastic in two South Carolina Estuaries: Occurrence, distribution, and composition. AB - Here we report on the distribution of microplastic contamination in two developed estuaries in the Southeastern United States. Average concentration in intertidal sediments of Charleston Harbor and Winyah Bay, both located in South Carolina, U.S.A., was 413.8 +/- 76.7 and 221.0 +/- 25.6 particles/m2, respectively. Average concentration in the sea surface microlayer of Charleston Harbor and Winyah Bay was 6.6 +/- 1.3 and 30.8 +/- 12.1 particles/L, respectively. Concentration in intertidal sediments of the two estuaries was not significantly different (p = 0.58), however, Winyah Bay contained significantly more microplastics in the sea surface microlayer (p = 0.02). While microplastic concentration in these estuaries was comparable to that reported for other estuaries worldwide, Charleston Harbor contained a high abundance of black microplastic fragments believed to be tire wear particles. Our research is the first to survey microplastic contamination in Southeastern U.S. estuaries and to provide insight on the nature and extent of contamination in these habitats. PMID- 29571368 TI - Sensitivity of indicators matters when using aggregation methods to assess marine environmental status. AB - The sensitivity of the 15 indicators included in a complex aggregation method (Nested Environmental status Assessment Tool), applied to a case study in the Caspian Sea in Iran, has been studied to discriminate between areas impacted and non-impacted by bathing activities. Two methods were used: (i) the 15 indicators were grouped into four groups (physicochemical, bacteria, plankton, and benthos) and each group was investigated separately (one-way sensitivity analysis), calculating NEAT values after omitting each group independently; and (ii) indicators were selected randomly, using 1000 Monte Carlo iterations, and removing from 1 to 14 indicators at each iteration. The results revealed that the abundance of Pontogammarus was the single indicator that made the difference in assessing the status among locations, differentiating bathing and non-bathing areas. Hence, this indicator is regarded as a monitoring element detecting the impacts produced by a management measure (beach nourishment) taken by the authorities to maintain the bathing activity. PMID- 29571369 TI - Comparative analysis of trace element accumulation in seagrasses Posidonia oceanica and Cymodocea nodosa: Biomonitoring applications and legislative issues. AB - This study aimed to compare the bioaccumulation patterns and translocation of trace elements (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) from the environment in the seagrasses Posidonia oceanica and Cymodocea nodosa. Results showed that P. oceanica has a higher capacity of accumulation. P. oceanica and C. nodosa accumulate mainly in roots and leaves, the main organs acting as potential bioindicators. No significant correlation was found between water and both seagrasses. In turn, P. oceanica and C. nodosa were correlated, to a different extent, with As, Cd, Cu, Ni and Zn in sediments. This study showed also that current European regulations do not provide an exhaustive set of legal concentration limits of trace elements in marine water and sediments. Seagrasses P. oceanica and C. nodosa can act as effective bioindicators of trace elements only if quality limits are set for the most toxic elements present in marine ecosystems. PMID- 29571370 TI - Biomarkers of physiological responses of Octopus vulgaris to different coastal environments in the western Mediterranean Sea. AB - The increase of pollutants in coastal seawater could produce several harmful biological effects on marine organisms related to the production of reactive oxygen species (ROS) causing cellular and tissue damages through oxidative stress mechanisms. Common octopuses (Octopus vulgaris) inhabiting coastal areas under high anthropogenic activity of Mallorca (W-Mediterranean Sea) have the ability to control oxidative damage by triggering antioxidant enzyme responses. Analyzing the digestive glands, octopuses from human-altered coastal areas showed higher activity of superoxide dismutase (SOD), catalase (CAT) and glutathione S transferase (GST) compared to octopuses from non-influenced coastal waters (i.e. marine reserve area). Higher metallothionein (MT) concentrations and lack of malondialdehyde (MDA) variations also reflect adaptations of O. vulgaris to polluted areas. This is the first study assessing the levels of the oxidative stress biomarkers on O. vulgaris in the Mediterranean Sea, revealing their usefulness to assess diverse environmental pollution effects on this relevant ecological and commercial species. PMID- 29571371 TI - Liver histopathology and biochemical biomarkers in Gobius niger and Zosterisessor ophiocephalus from polluted and non-polluted Tunisian lagoons (Southern Mediterranean Sea). AB - The aim of this study was to appraise the response of a multi-marker approach in fish species, Gobius niger and Zosterisessor ophiocephalus, in a polluted lagoon (Bizerte lagoon: MB and ML sites) and in a reference site (Ghar-El-Melh lagoon entrance) by the analysis of physiological indexes, liver histopathology and some biochemical biomarkers. The results showed liver hypertrophy in fish collected from Bizerte lagoon as well as many non-specific lesions, unlike the reference site. All Bizerte lagoon sites had the same prevalence of histopathological lesions, but the mean intensity (MI) of parasites seemed to be more sensible as an indicator of pollution levels. Indeed, parasite MI was more important in MB site that has a higher pollution level. Also, biochemical biomarkers showed an induction in Bizerte lagoon sites with some differences within sites and species. The impact of the continuous release of pollution on the biomarker's response is discussed. PMID- 29571372 TI - Limited impact of beach nourishment on macrofaunal recruitment/settlement in a site of community interest in coastal area of the Adriatic Sea (Mediterranean Sea). AB - Beach nourishment is a widely utilized solution to counteract the erosion of shorelines, and there is an active discussion on its possible consequences on coastal marine assemblages. We investigated the impact caused by a small-scale beach nourishment carried out in the Western Adriatic Sea on macrofaunal recruitment and post-settlement events. Artificial substrates were deployed in proximity of nourished and non-manipulated beaches and turbidity and sedimentation rates were measured. Our results indicate that sedimentation rates in the impacted site showed a different temporal change compared to the control sites, suggesting potential modifications due to the beach nourishment. The impact site was characterized by subtle changes in terms of polychaete abundance and community structure when compared to controls, possibly due to beach nourishment, although the role of other factors cannot be ruled out. We conclude that small-scale beach nourishments appear to be an eco-sustainable approach to contrast coastal erosion. PMID- 29571373 TI - Trace elements concentrations in squids consumed in Shandong Province China and their associated risks to the human health. AB - Determination of ten metal levels in 160 squid samples caught from offshore and the oceanic fishing locations by ICP-MS was made. The mean metal concentration in the squid muscles decreasing in the order of: Zn, Fe, Cu, As, Mn, Se, Cd, Pb, Cr and Ni. Metal concentrations in the squids were assessed for human uses according to provisional tolerable weekly intake (PTWI) and provisional tolerable daily intake (PTDI).The estimated hazard quotients for the individual metals from squids were found in accordance to the following sequence: As > Cd > Cu > Se > Cr > Zn > Pb > Fe > Mn > Ni, with the greatest hazard upon human health coming primarily from As (1.34 < HQ < 1.73 in the Loliginidae from two offshore sampling sites and the Humboldt squid from the eastern Pacific Ocean). In regards to the heavy metal pollution of the coastal sea areas, the squids captured from offshore sites might pose a higher potential health risk to consumers compared to those from the ocean. PMID- 29571374 TI - Shifts in phytoplankton community structure in response to hydrological changes in the shallow St Lucia Estuary. AB - Hydrological regimes are key in shaping the structure of phytoplankton communities in estuaries. Because anthropogenic disturbances often alter the quantity and quality of riverine inputs, this research focused on investigating phytoplankton dynamics in the St. Lucia Estuary, since being reconnected to the Mfolozi River. Due to the closed mouth state of the estuary, the input from the river resulted in oligohaline (>=5) conditions and the characteristic reverse salinity gradient to persist throughout the study (i.e. one year). Model results indicated that phytoplankton communities were structured by rainfall, light transmittance and depth, while shifts between dominant groups were driven by salinity and flow season. The persistence of chlorophytes and euglenophytes as the co-dominant functional group indicates the freshening and nutrient-enriched nature of the river. This study provides the first detailed account documenting the response of the phytoplankton community to recent restoration efforts in the St Lucia Estuary, a Ramsar Site.

AB - Information is scarce on historical trends of perfluoroalkyl substances (PFASs) in the coastal environment. In this study, four sediment cores were collected from semi-enclosed bays of Korea to investigate the pollution history, contamination profiles, and environmental burden of PFASs. The total PFAS concentrations in sediment cores ranged from 6.61 to 821 pg/g dry weight. The highest concentrations of PFASs were found in surface or sub-surface sediments, indicating on-going contamination by PFASs. Historical trends in PFASs showed a clear increase since the 1980s, which was consistent with the global PFAS consumption pattern. Concentrations of PFASs were dependent on the organic carbon content in sediment cores. PFOS and longer-chain PFASs were predominant in all of the sediment cores. In particular, a large proportion of longer-chain PFASs was observed in the upper layers of the sediment cores from industrialized coastal regions. Inventories and fluxes estimated for PFASs were similar to those for PCDD/Fs.

AB - Sediments samples from six seaports of NSW, Australia were analysed for the presence of metal contamination. Geoaccumulation index (Igeo), enrichment factor (EF), pollution load index (PLI), potential ecological risk (PER) and sediment pollution index (SPI) along with multivariate statistical analysis were used to identify the pollution pattern and possible sources of metals in the ports. The results demonstrate Cu, Pb and Zn pollution (Igeo > 5) at most sites and enrichment of As, Ni, Mn (EF > 3) and other metals. The PER recommends serious pollution at Port Kembla and Eden. By contrast, PLI and SPI demonstrate high contamination in all ports with exception of Port Botany and Yamba. PCA and cluster analysis detected major groups of elements in which three distinct clusters of pollutants and sites were apparent by dendrogram which portray simple and effective baseline scenarios for port activity-related quality assessment of surface sediments. PMID- 29571378 TI - ALEX index enables detection of alien macroalgae invasions across habitats within a marine protected area. AB - A modified version of the ALien Biotic IndEX (ALEX) has been recently proposed to evaluate biological invasions in macroalgal assemblages. ALEX was applied in a Marine Protected Area where a recreational-fishing port is present testing the following hypotheses: ALEX increases with the distance from the port, it changes between the two directions off the port and it changes among three different habitats: Cystoseira beds, algal turf and dead matte of the seagrass Posidonia oceanica. A total of 78 native macroalgal taxa and 4 introduced species were found, the Chlorophyta Caulerpa cylindracea and the Rhodophyta Apoglossum gregarium, Acrothamnion preissii and Womersleyella setacea. All study sites were in high quality status highlighting that the assemblages investigated were at an early stage of NIS invasion. However, ALEX detected different values among conditions and habitats within the MPA, suggesting a local dynamics of NIS spread and different resistance to invasion of the investigated habitats.

AB - This is the first surveillance study using methacrylate monolithic supports to concentrate environmental coastal water samples, prior to molecular target detection by RT-qPCR. Rotaviruses (RoV) and Noroviruses (NoV) were monitored in a polluted area at the Bay of Koper (Gulf of Trieste, Northern Adriatic Sea) and at a nearby bathing area and mussel farm areas. RoV and NoV are released into the Bay of Koper, with higher rates close to the discharge of the wastewater treatment plant, however, they can be detected at recreational and mussel farming areas. Our results showed that water bodies considered safe based on FC concentrations, can still have low, yet potentially infective, concentrations of human viruses. PMID- 29571379 TI - Cost effective and practically viable oil spillage mitigation: Comprehensive study with biochar. AB - Biochar is carbonaceous mass that is produced from pyrolysis or gasification of biomass. It is so far majorly explored for soil remediation application, but recently it has attracted a lot of interest because of its unexplored applications in the area of adsorption. In this work, detailed study on biochars produced from two different feeds (rice husk and saw dust), at two different temperatures (450 and 550 degrees C) and two different rates (fast and slow) of pyrolysis are discussed for oil spill mitigation. Biochar is characterized in detail by various techniques such as FTIR, 13C CPMAS, FESEM, RAMAN, TGA to determine the structural composition and observe the extent of pyrolysis. Tests to assess the performance of produced biochars as sorbents for oil spill mitigation have been demonstrated. The as produced biochars selectively absorbed crude oil from oil/water biphasic mixtures in various capacities. PMID- 29571380 TI - Inorganic arsenic causes apoptosis cell death and immunotoxicity on European sea bass (Dicentrarchus labrax). AB - Inorganic arsenic (As) is one of the most toxic pollutants in the water. We have studied their effects on the marine teleost European sea bass (Dicentrarchus labrax) at 2 and 10 days of 5 MUM of As2O3 (sub-lethal doses) waterborne exposure. Arsenic accumulates in liver and gill tissues. The expression profile of five genes (bax, blc2, casp3, casp8 and casp9) involved in apoptosis cell death confirmed apoptotic effects in liver, slight changes in gill and no effects in skin according with the histopathology findings. Total IgM level and peroxidase activities were increased at 2 and 10 days, respectively. The bactericidal activity was decreased at 2 days after As exposure. A general decrease of cellular immune activities with significant differences in the case of respiratory burst activity was observed after 2 and 10 days of exposure. This work describes for the first time the effects of As exposure on European sea bass. PMID- 29571381 TI - A modeling approach for reposition dynamics of litter composition in coastal areas of the city of Santos, Sao Paulo, Brazil. AB - Given the complexity of the dynamics in litter reposition, our objective was modeling the possible main and interaction effects of tidal oscillations, seasons of the year and the moon phases over the solid waste in Santos beaches. A total of 80 collections were carried out using quadrat sampling, from which we classified, counted and weighed all residue items. We fitted mixed Hurdle models to the output datasets and performed hypotheses tests based on this framework. We found plastic to be the most abundant residue in all seasons, moon phases and tides, followed by Styrofoam and wood. Our models suggest the strongest effect was due to seasonal variations, which, in turn, may be related to different human activities. Although the dynamics of different components showed independency of all interaction structures, plastics depended on the interaction of tide and season, whose impact over estuarine life and ecosystem services shall be further investigated. PMID- 29571382 TI - Marine pollution in the Libyan coastal area: Environmental and risk assessment. AB - A comprehensive assessment of the potential adverse effects on environment and human health generated by the inputs of chemicals from the most important Libyan petrochemical plant is presented. Ecotoxicological risk associated with the presence of As, Hg, Ni, Zn and PAHs in marine sediments is low or moderate, with a probability of toxicity for ecosystem <9% and <20% for heavy metals and PAHs respectively. However, surface sediments result strongly enriched in Hg and As of anthropogenic origin. Investigation of metals in fish allowed to assess potential risks for human populations via fish intake. Target hazard quotients values indicate potential risk associated to toxic metals exposure by fish consumption and lifetime cancer risk (TR) values highlight a potential carcinogen risk associated to As intake. Noteworthy, the presented results provide an unprecedented environmental dataset in an area where the availability of field data is very scant, for a better understanding of anthropogenic impacts at Mediterranean scale. PMID- 29571383 TI - Beach litter along various sand dune habitats in the southern Adriatic (E Mediterranean). AB - Marine litter accumulates on sandy beaches and is an important environmental problem, as well as a threat to habitat types that are among the most endangered according to EU legislation. We sampled 120 random plots (2 * 2 m) in spring 2017 to determine the distribution pattern of beach litter along the zonation of habitat types from sea to the inland. The most frequent litter items were plastic, polystyrene and glass. A clear increase of litter cover along the sea inland gradient is evident, and foredunes and pine forests have the highest cover of litter. Almost no litter was present in humid dune slacks. Shoreline and recreational activities are the major source of beach litter, while ocean/waterway activities are more important in the aphytic zone and strandline. PMID- 29571384 TI - Spatial and vertical distribution of radiocesium in seawater of the East China Sea. AB - The 137Cs activity in surface water of the East China Sea (ECS) was 0.66-1.36 Bq m-3 during May of 2011. The low activities were observed in the Changjiang Estuary and Zhejiang-Fujian coast and high activities were observed in the south offshore and Kuroshio Current pathway, suggesting that the influence from the current system in the ECS. The 134Cs were undetectable (<0.03 Bq m-3) and the contribution of the Fukushima accident to ECS is estimated to be below 3%; hence it is negligible during the investigation period. Using the vertical profiles of 137Cs in the ECS, the mass balance is obtained, which suggests that the oceanic input dominates the 137Cs source in the ECS. 137Cs is potentially useful to trace water mass movement in the ECS. Our study provides comprehensive baseline of 137Cs in the ECS for evaluation of the possible influence of the nuclear power plants in the future. PMID- 29571385 TI - Plastic ingestion by Tristram's Storm-petrel (Oceanodroma tristrami) chicks from French frigate shoals, Northwestern Hawaiian Islands. AB - This study provides the first quantification of plastic ingestion in the Tristram's Storm-petrel (Oceanodroma tristrami) in over 20 years. We found 100% plastic incidence in 57 chicks collected opportunistically over four breeding seasons (2007, 2010, 2011, 2012), with the mass of ingested plastic per individual ranging from 0.1 to 2.8 g (<=3.3% adult mass). While plastic occurred in every bird we examined, the proventriculus contained significantly more plastic, more fragments, and larger fragments than the gizzard. Most of the ingested plastic (97.5% by mass) consisted of fragments, ranging in length from 0.4 to 11.6 mm and ranging in surface area from 0.07 to 45.21 mm2. While fragments were ubiquitous, occurring in every proventriculus and gizzard we analyzed, Tristram's Storm-petrels also ingested foam, line and sheets. Digital analysis of 1425 ingested plastic fragments documented a wide range of colors, involving shades of white, yellow, orange, red, blue, green, and black. PMID- 29571386 TI - What is the best endpoint for assessing environmental risk associated with acidification caused by CO2 enrichment using mussels? AB - Carbon capture and storage is a technology that has been widely determined to be one of the best choices for the short-term reduction of atmospheric CO2 emissions. The aim of this study was to analyze the effects of CO2 enrichment in the ocean on the mussel species Mytilus galloprovincialis using three different endpoints: mortality, embryo-larval development, and neutral red retention time assays (NRRT). Acute effects were found to be associated with a pH values of 6.0 while citotoxity effects and embryo-larval development were associated with a pH value of 7.0. The NRRT assay and embryo-larval development can be recommended as good endpoints for assessing the environmental risk associated with acidification by CO2 enrichment because they provide sensitive responses on the effects of changes in seawater pH on mussels in a short period of time. Moreover, this study may support policymakers in finding appropriate solutions for the conservation of marine ecosystems. PMID- 29571387 TI - Occurrence of Ostreopsis lenticularis (Dinophyceae: Gonyaulacales) from the Archipielago de Revillagigedo, Mexican Pacific. AB - From December 2016 to May 2017, 22 phytoplankton surface samples were collected with a 20-MUm mesh net at three islands of the Archipielago de Revillagigedo (Partida, Socorro and San Benedicto), Mexican Pacific. The sites depth was approximately 20-80 m; the surface water temperature was 21-27 degrees C. The potentially toxic benthic dinoflagellate Ostreopsis lenticularis was present in all the samples. Cells had a lenticular to broadly oval shape, 65-100 MUm long and 50-80 MUm wide. The taxonomy of the genus Ostreopsis has been unclear due to equivocal ascribing some taxonomic features among species. The identification of specimens from the archipelago was made based on the most important taxonomic characteristics: the thecal plates, the presence of two types of thecal pores (larger and smaller), and the lack of cingulum undulation. The studied cells are compared with O. cf. siamensis, O. labens and O. marina. This is the first record of the species in the archipelago waters. PMID- 29571388 TI - Fake news. PMID- 29571389 TI - Elemental concentration and potential ecological risk assessment of reef associated surface sediments of Appa Island, Gulf of Mannar Biosphere Reserve, Southeast coast of India. AB - Thirty three surface sediments were collected for the present study to assess the elemental concentration and its associated ecological risk in the reef associated surface sediments, Appa Island, Gulf of Mannar Biosphere Reserve, South east coast of India. The distribution of calcium carbonate in the reef sediments is controlled by coral debris and shell fragments whereas the Organic matter (OM) content are chiefly derived from mangroves and sea grasses. The circulation of trace elements and Fe, Mn are controlled by the fluvial process and re-suspended sediments. The concentration of Pb was primarily controlled by migration of pollutants through long shore sediment transport process. The main source of Pb in the study area is from coal incinerating power plants and coal handling operations from harbors. PMID- 29571390 TI - A UAV and S2A data-based estimation of the initial biomass of green algae in the South Yellow Sea. AB - Previous studies have shown that the initial biomass of green tide was the green algae attaching to Pyropia aquaculture rafts in the Southern Yellow Sea. In this study, the green algae was identified with unmanned aerial vehicle (UAV), an biomass estimation model was proposed for green algae biomass in the radial sand ridge area based on Sentinel-2A image (S2A) and UAV images. The result showed that the green algae was detected highly accurately with the normalized green-red difference index (NGRDI); approximately 1340 tons and 700 tons of green algae were attached to rafts and raft ropes respectively, and the lower biomass might be the main cause for the smaller scale of green tide in 2017. In addition, UAV play an important role in raft-attaching green algae monitoring and long-term research of its biomass would provide a scientific basis for the control and forecast of green tide in the Yellow Sea. PMID- 29571391 TI - Enhancing passive sampling tools for detecting marine bioinvasions. AB - Early detection is important for successful management of invasive species, but optimising monitoring systems to detect multiple species from different taxonomic groups remains a major challenge. Settlement plates are often used to monitor non indigenous marine species (NIMS) associated with vessel biofouling, but there have been few assessments of their fitness-for-purpose. We deployed arrays of settlement plates ("settlement arrays") containing combinations of treatments that reflected conditions associated with the vessel transport pathway (i.e., copper based antifouling coatings, shaded habitat) to determine the treatment combinations that maximised NIMS diversity. Horizontal (shaded) treatments preferentially sampled higher NIS diversity than vertical plates. Although plates with copper-based biocides had larger proportions of NIS to indigenous species, they sampled only a subset of NIS diversity. Overall diversity was greatly enhanced through use of multiple treatments, demonstrating benefits of multi faceted sampling arrays for maximising the potential taxonomic and species richness. PMID- 29571392 TI - Distributions of particulate and dissolved phosphorus in aquatic habitats of Peninsular Malaysia. AB - Particulate phosphorus was the dominant phosphorus species and accounted for 72 +/- 5% of total phosphorus in coastal habitats, 63 +/- 4% in estuaries, 58 +/- 6% in lakes and 80 +/- 7% in aquaculture farms whereas dissolved inorganic phosphorus (DIP) and dissolved organic phosphorus (DOP) were minor components. Correlation analyses (DIP vs Chl a; R2 = 0.407, df = 31, p < 0.001) suggested phosphorus limiting conditions in lakes, which was corroborated with the highest alkaline phosphatase activity (APA) that fluctuated from 0.38 to 41.14 nmol L-1 min-1. In contrast, APA was elevated in coastal habitats and estuaries only when DIP concentration decreased below 0.9 MUM. Moreover size-fractionation experiment showed that the highest APA was detected in the 0.2-2 MUm pico-size fraction. Our results suggested that the main APA in coastal habitats and estuaries was from phototrophic pico-eukaryotes and heterotrophic bacteria, and regulated largely by DIP availability. PMID- 29571393 TI - Sedimentary mercury (Hg) in the marginal seas adjacent to Chinese high-Hg emissions: Source-to-sink, mass inventory, and accumulation history. AB - We comprehensively investigated sedimentary Hg in Yellow and East China Seas (YECSs), which constitute potentially important depocenters for large anthropogenic Hg emissions from mainland China. A large dataset of Al-TOC-Hg concentrations led to an in-depth understanding of sedimentary Hg in the entire YECSs, including distribution and its determinants, source-to-sink, background levels, inventory in flux and budget, and accumulation history. Especially, the net atmospheric Hg flux to the sediments was estimated to be 1.3 * 10-5 g/m2/yr, which corresponded reasonably well to that calculated using a box model. About 21.2 tons of atmospheric Hg (approximately 4% of the total anthropogenic atmospheric Hg emissions from China) were buried annually in the YECS basin. This result implies that most of atmospheric Hg from China is transferred to the surface of the Pacific (including the East/Japan Sea and South China Sea) by the westerlies and, consequently, can play a critical role in open-sea aquatic ecosystems. PMID- 29571394 TI - Evidence of marine debris usage by the ghost crab Ocypode quadrata (Fabricius, 1787). AB - Sandy beaches are sites of marine debris stranding, but the interaction of beach biota with waste is poorly studied. The objective of this study was to investigate whether the ghost crab Ocypode quadrata selects marine debris by types using a non-destructive method on sandy beaches of Southeastern Brazil. We found marine debris in 7% of 1696 surveyed burrows, and the ghost crabs selectivity was mainly by soft plastic (30%), straw (11%), rope (6%) and foam (4%). Burrows with marine debris showed higher occupation rate (~68%) compared to burrows without debris (~28%), indicating that these materials may increase the capacity of ghost crabs to memorize their burrows placement (homing). The percentage of marine debris was not always related to their amount in the drift line, but ghost crabs used more debris near urbanized areas. Future studies should test whether ghost crabs are using marine debris for feeding, homing or other mechanisms. PMID- 29571395 TI - The contaminant legacy from historic coastal landfills and their potential as sources of diffuse pollution. AB - Prior to modern environmental regulation landfills in low-lying coastal environments were frequently constructed without leachate control, relying on natural attenuation within inter-tidal sediments to dilute and disperse contaminants reducing environmental impact. With sea level rise and coastal erosion these sites may now pose a pollution risk, yet have received little investigation. This work examines the extent of metal contamination in saltmarsh sediments surrounding a historic landfill in the UK. Patterns of sediment metal data suggest typical anthropogenic pollution chronologies for saltmarsh sediments in industrialised nations. However, many metals were also enriched at depth in close proximity to the landfill boundary and are indicative of a historical leachate plume. Though this total metal load is low, e.g., c. 1200 and 1650kg Pb and Zn respectively, with >1000 historic landfills on flood risk or eroding coastlines in the UK this could represent a significant, yet under-investigated, source of diffuse pollution. PMID- 29571396 TI - Monitoring of Polycyclic Aromatic Hydrocarbons (PAHs) in Scottish Deepwater environments. AB - Polycyclic aromatic hydrocarbons (PAHs) were measured in environmental samples (sponges, fish and sediment) collected in 2014 and 2016 from the Faroe-Shetland Channel and Rosemary Bank Seamount. These data could be used to provide a baseline against which any changes can be assessed in the event of an oil spill and contribute to any environmental impact assessment. Concentrations in all samples were low, often below the detection limits, and were typical of reference sites. Sponges can be used as an alternative indicator species to mussels for monitoring PAHs in the marine environment as they can accumulate PAHs from both the dissolved and particulate phase. PAH concentrations in marine sponges from Scottish waters have not previously been reported. Concentrations were low, but contained a higher proportion of heavier 4- to 6-ring PAHs compared to the fish samples. PMID- 29571397 TI - A simple Bird Sensitivity to Oil Index as a management tool in coastal and marine areas subject to oil spills when few biological information is available. AB - This study sought to develop a simple index for ranking birds' environmental sensitivity to oil in which birds are used as biological indicators. The study area consisted of both the Santos Estuarine System (SES), and the Laje de Santos Marine State Park (LSMSP), located in Southeastern Brazil. Information on the bird species and their feeding and nesting behaviors were obtained from the literature and were the basis of the sensitivity index created. The SES had a higher number of species, but only about 30% were found to be highly sensitive. The LSMSP presented a much lower number of species, but all of them were considered to be highly sensitive to oil. Due to its simplicity, this index can be employed worldwide as a decision-making tool that may be integrated into other management tools, particularly when robust information on the biology of birds is lacking. PMID- 29571398 TI - Microplastics in a wind farm area: A case study at the Rudong Offshore Wind Farm, Yellow Sea, China. AB - Despite the rapid construction of offshore wind farms, the available information regarding the risks of this type of development in terms of emerging pollutants, particularly microplastics, is scarce. In this study, we quantified the level of microplastic pollution at an offshore wind farm in the Yellow Sea, China, in 2016. The abundance of microplastics was 0.330 +/- 0.278 items/m3 in the surface water and 2.58 +/- 1.14 items/g (dry) in the sediment. To the best of our knowledge, the level of microplastic pollution in our study area was slightly higher than that in coastal areas around the world. The microplastics detected in the surface waters and sediments were mainly fibrous (75.3% and 68.7%, respectively) and consisted of some granules and films. The microplastics in the samples might originate from garments or ropes via wastewater discharge. The abundance of plastic in the water and sediment samples collected from the wind farm area was lower than that in the samples collected from outside the wind farm area. The anthropogenic hydrodynamic effect was the main factor affecting the local distribution of microplastics. The presence of a wind farm could increase the bed shear stress during ebb tide, disturbing the bed sediment, facilitating its initiation and transport, and ultimately increasing the ease of washing away the microplastics adhered to the sediment. This study will serve as a reference for further studies of the distribution and migration of microplastics in coastal zones subjected to similar marine utilization. PMID- 29571399 TI - Effects of corresponding and non-corresponding contaminants on the fate of sulfonamide and quinolone resistance genes in the Laizhou Bay, China. AB - The environmental behaviors and migration patterns of antibiotic resistance genes (ARGs) have attracted considerable research interest. However, there has been little research concerning the effects of corresponding and non-corresponding contaminants on the fate of ARGs in coastal environments. In the present study, the distribution of intI1, sul1, sul2, qnrS and aac(6')-Ib were analyzed in water and sediment samples of Laizhou Bay in the context of corresponding and non corresponding contaminants. The abundance of intI1, sul1 and sul2 genes exhibited a clear decreasing trend extending from the inner estuary to the coastal area. Strong and positive correlations existed between sul1/sul2 and sulfonamide antibiotic residues in sediments, and between the abundances of intI1 and sul1/sul2. Statistical analyses indicated that non-corresponding contaminants were partially correlated with ARG abundances. These results suggest that non corresponding contaminants may have direct or indirect influences on the abundances of ARGs and intI1 in the Laizhou Bay. PMID- 29571400 TI - Temporal changes in benthic macrofauna on the west coast of Norway resulting from human activities. AB - Quantitative analyses of soft bottom invertebrate fauna from four Norwegian sill fjords show increased macrofaunal abundance, species richness, and a considerably changed benthic deep water macrofaunal composition in the inner parts of the fjord system. In retrospect, the analyses show significantly altered benthic macrofaunal community structure that was not reflected by the changes in the Shannon-Wiener diversity indices during regular monitoring. The observed changes are mainly due to an increased abundance of opportunistic species, especially of the polychaete Polydora sp. during the last 10-15 years which is correlated significantly to declining dissolved oxygen, rising temperature in the bottom water and increasing total organic matter in the sediment. Possible anthropogenic and climatic impact factors related to the observed macrofaunal changes and environmental consequences of the changes are discussed. PMID- 29571401 TI - Locating fish bomb blasts in real-time using a networked acoustic system. AB - Results are presented of a demonstration of real-time fish blast location in Sabah, Malaysia using a networked hydroacoustic array based on the ShotSpotter gunshot location system. A total of six acoustic sensors - some fixed and others mobile - were deployed at ranges from 1 to 9 km to detect signals from controlled test blasts. This allowed the blast locations to be determined to within 60 m accuracy, and for the calculated locations to be displayed on a map on designated internet-connected computers within 10 s. A smaller three-sensor system was then installed near Semporna in Eastern Sabah that determined the locations of uncontrolled blasts set off by local fishermen. The success of these demonstrations shows that existing technology can be used to protect reefs and permit more effective management of blast fishing activity through improved detection and enforcement measures and enhanced community engagement. PMID- 29571402 TI - Determining light stress responses for a tropical multi-species seagrass assemblage. AB - Existing mitigations to address deterioration in water clarity associated with human activities are based on responses from single seagrass species but may not be appropriate for diverse seagrass assemblages common to tropical waters. We present findings from a light experiment designed to determine the effects of magnitude and duration of low light on a mixed tropical seagrass assemblage. Mixed assemblages of three commonly co-occurring Indo-West Pacific seagrasses, Cymodocea serrulata, Halodule uninervis and Halophila ovalis were grown in climate-controlled tanks, where replicate pots were subjected to a gradient in light availability (0.9-21.6 mols PAR m-2 day-1) for 12 weeks. Increased shading resulted in declines in growth and changes in cellular and photosynthesis responses for all species, although time-scale and magnitude of response were species-specific. Applying management criteria (e.g. thresholds) relevant to one species may under- or over-estimate potential for impact on other species and the meadow as a whole. PMID- 29571403 TI - Intertidal geothermal hot springs as a source of trace elements to the coastal zone: A case study from Bahia Concepcion, Gulf of California. AB - We investigated the influence of the intertidal geothermal hot spring (GHS) on the biogeochemistry of trace elements in Santispac Bight, Bahia Concepcion (Gulf of California). The geothermal fluids were enriched in As and Hg mainly in ionic form. The suspended particulate matter of the GHS had elevated enrichment factor (EF) >1 of As, Bi, Cd, Co, Cu, Mn, Mo, Sb, Sn, Sr, Ti, U and Zn. The sediment core from GHS1 had high concentration of As, Hg, Corg, S, V, Mo, and U and the extremely high EF of these elements at 8cm of the core. The maximum bioaccumulation of As and Hg was in seaweeds Sargassum sinicola collected near the GHS2. The results confirm the input of trace elements to the coastal zone in Bahia Concepcion from geothermal fluids and the evident modification of the chemical composition of the adjacent marine environment. PMID- 29571404 TI - Effects of sub-seabed CO2 leakage: Short- and medium-term responses of benthic macrofaunal assemblages. AB - The continued rise in atmospheric carbon dioxide (CO2) levels is driving climate change and temperature shifts at a global scale. CO2 Capture and Storage (CCS) technologies have been suggested as a feasible option for reducing CO2 emissions and mitigating their effects. However, before CCS can be employed at an industrial scale, any environmental risks associated with this activity should be identified and quantified. Significant leakage of CO2 from CCS reservoirs and pipelines is considered to be unlikely, however direct and/or indirect effects of CO2 leakage on marine life and ecosystem functioning must be assessed, with particular consideration given to spatial (e.g. distance from the source) and temporal (e.g. duration) scales at which leakage impacts could occur. In the current mesocosm experiment we tested the potential effects of CO2 leakage on macrobenthic assemblages by exposing infaunal sediment communities to different levels of CO2 concentration (400, 1000, 2000, 10,000 and 20,000 ppm CO2), simulating a gradient of distance from a hypothetic leakage, over short-term (a few weeks) and medium-term (several months). A significant impact on community structure, abundance and species richness of macrofauna was observed in the short term exposure. Individual taxa showed idiosyncratic responses to acidification. We conclude that the main impact of CO2 leakage on macrofaunal assemblages occurs almost exclusively at the higher CO2 concentration and over short time periods, tending to fade and disappear at increasing distance and exposure time. Although under the cautious perspective required by the possible context-dependency of the present findings, this study contributes to the cost-benefit analysis (environmental risk versus the achievement of the intended objectives) of CCS strategies. PMID- 29571405 TI - Improving the implementation of marine monitoring in the northeast Atlantic. AB - Marine monitoring in the northeast Atlantic is delivered within identifiable monitoring themes, established through time and defined by the geographical area and policy drivers they serve, the sampling methodologies they use, their assessment methodologies, their funding and governance structures and the people or organisations involved in their implementation. Within a monitoring theme, essential components for effective monitoring are governance, strategy and work plan, sampling protocols, quality assurance, and data and assessment structures. This simple framework is used to analyse two monitoring theme case studies; national ecosystem health monitoring, and regional fish stock monitoring. Such essential component analyses, within marine monitoring themes, can help improve monitoring implementation by identifying gaps and overlaps. Once monitoring themes are recognised, explicitly defined and streamlined, travel towards integrated monitoring may be made easier as the current lack of clarity in thematic marine monitoring implementation is one barrier to integration at both national and regional scales. PMID- 29571406 TI - Securing a port's future through Circular Economy: Experiences from the Port of Gavle in contributing to sustainability. AB - Ports are an important player in the world, due to their role in global production and distributions systems. They are major intermodal transport hubs, linking the sea to the land. For all ports, a key requirement for commercial and economic viability is to retain ships using them and to remain accessible to those ships. Ports need to find approaches to help them remain open. They must ensure their continued economic viability. At the same time, they face increasing pressure to become more environmentally and socially conscious. This paper examines the approach taken by the Port of Gavle, Sweden, which used contaminated dredged materials to create new land using principles of Circular Economy. The paper demonstrates that using Circular Economy principles can be a viable way of securing a port's future and contributing to its sustainability, and that of the city/region where it operates. PMID- 29571407 TI - Source identification and risk assessment based on fractionation of heavy metals in surface sediments of Jiaozhou Bay, China. AB - To identify sources and evaluate ecological risks of heavy metals in sediments of Jiaozhou Bay, contents and chemical fractions of Cd, Cr, Cu, Pb, Zn, Ni, Sb and Sn were studied. Results suggested that higher metal contents appeared at inner bay and near marine dumping area. Labile fractions of heavy metals accounted for 0.5-77% (~36%) of total contents indicating their significant anthropogenic sources. The enrichment levels of Cd and Sb were relatively higher. Cu, Ni, Cd and Zn were at low to medium risks. Cr, Pb, Sn and Sb were at no or low risks. Total contents of heavy metals were mainly controlled by natural sources, while anthropogenic inputs were important sources of labile fractions of heavy metals in sediments of Jiaozhou Bay with industrial and domestic activities as main contributors for Cu, Pb, Zn, Cr, Ni and Sn, and agricultural activities for Cd and regional coal combustion for Sb. PMID- 29571408 TI - Widespread sewage pollution of the Indian River Lagoon system, Florida (USA) resolved by spatial analyses of macroalgal biogeochemistry. AB - The Indian River Lagoon (IRL) system, a poorly flushed 240 km long estuary in east-central Florida (USA), previously received 200 MLD of point source municipal wastewater that was largely mitigated by the mid-1990's. Since then, non-point source loads, including septic tank effluent, have become more important. Seventy sites were sampled for bloom-forming macroalgae and analyzed for delta15N, % nitrogen, % phosphorus, carbon:nitrogen, carbon:phosphorus, and nitrogen:phosphorus ratios. Data were fitted to geospatial models showing elevated delta15N values (>+50/00), matching human wastewater in most of the IRL system, with elevated enrichment (delta15N >= +70/00 to +100/00) in urbanized portions of the central IRL and Banana River Lagoon. Results suggest increased mobilization of OSDS NH4+ during the wetter 2014 season. Resource managers must improve municipal wastewater treatment infrastructure and commence significant septic-to-sewer conversion to mitigate nitrogen over-enrichment, water quality decline and habitat loss as mandated in the Tampa and Sarasota Bays and the Florida Keys.

AB - Microplastic ingestion has been reported for several marine species, but the level of contamination in transitional systems and associated biota is less known. The aim of this study was to assess the occurrence of microplastic ingestion in three commercial fish species: the sea bass (Dicentrarchus labrax), the seabream (Diplodus vulgaris) and the flounder (Platichthys flesus) from the Mondego estuary (Portugal). Microplastics were extracted from the gastrointestinal tract of 120 individuals by visual inspection and digestion solution. A total of 157 particles were extracted from 38% of total fish (96% fibers), with 1.67 +/- 0.27 (SD) microplastics per fish. Significantly higher amount of ingested microplastics was recorded for D. vulgaris (73%). The dominant polymers identified by MU-FTIR were polyester, polypropylene and rayon (semi synthetic fiber). It is reported for the first time the presence of this pollutant in fish populations from the Mondego estuary raising concerns on their potential negative effects. PMID- 29571410 TI - Pollutant bioaccumulation in the California spiny lobster (Panulirus interruptus) in San Diego Bay, California, and potential human health implications. AB - While the California spiny lobster (Panulirus interruptus) is an important commercial and recreational fishery species in California, there is a lack of data on bioaccumulation for the species. This study examined pollutant tissue concentrations in lobsters from San Diego Bay, California. Observed lobster pollutant tissue concentrations in tail muscle were compared to State of California pollutant advisory levels. Concentrations were then used to conduct risk assessment using catch data from the California Department of Fish and Wildlife. Study results found little bioaccumulation of organic pollutants in tail tissue, likely due to low observed lipids. Mercury was present, predominantly in methyl form, at concentrations above advisory levels. Recreational catch data for San Diego Bay showed increased non-cancer risk for fishers at the 90th percentile or greater of reported annual catch. Further studies should focus on non-tail tissues, as exploratory whole lobster samples (n = 2) showed elevated organic pollutants and metals.

AB - Tarballs are semisolid blobs of crude oil, normally formed due to weathering of crude-oil in the sea after any kind of oil spills. Microorganisms are believed to thrive on hydrocarbon-rich tarballs and possibly assist in biodegradation. The taxonomy of ecologically and economically important tarball-associated microbes, however, needs improvement as DNA-based identification and phylogenetic characterization have been scarcely incorporated into it. In this study, bacteria and fungi associated with tarballs from touristic Betul beach in Goa, India were isolated, followed by phylogenetic analyses of 16S rRNA gene and the ITS sequence data to decipher their clustering patterns with closely-related taxa. The gene sequence analyses identified phylogenetically diverse 20 bacterial genera belonging to the phyla Proteobacteria (14), Actinobacteria (3), Firmicutes (2) and Bacteroidetes (1), and 8 fungal genera belonging to the classes Eurotiomycetes (6), Sordariomycetes (1) and Leotiomycetes (1) associated with the Betul tarball samples. Future studies employing a polyphasic approach, including multigene sequence-data, are needed for species-level identification of culturable tarball-associated microbes. This paper also discusses potentials of tarball-associated microbes to degrade hydrocarbons. PMID- 29571412 TI - Microplastic analysis in the South Funen Archipelago, Baltic Sea, implementing manta trawling and bulk sampling. AB - Microplastic contamination in surface waters of the South Funen Archipelago in Denmark was assessed. Therefore, ten manta trawls were conducted in June 2015. Moreover, 31 low-volume bulk samples were taken to evaluate, whether consistent results in comparison to the net-based approach can be obtained. Microplastic contamination in the South Funen Archipelago (0.07 +/- 0.02 particles/m3) is slightly below values reported before. The sheltered position of the study area, low population pressure on adjacent islands and the absence of any major potential point sources were identified as major factors explaining the low concentration of microplastics. Within the Archipelago, harbors or marinas and the associated vessel traffic are the most probable sources of microplastics. The concentration of microplastics in low-volume bulk samples is not comparable to manta trawl results. This is mainly due to insufficient representativeness of the bulk sample volumes. PMID- 29571413 TI - Foraminiferal single chamber analyses of heavy metals as a tool for monitoring permanent and short term anthropogenic footprints. AB - In order to establish environmentally sustainable industries there is a need for high-resolution temporal and spatial monitoring of heavy metal pollutants even at low concentrations before they become hazardous for local ecosystems. Here we present single chamber records of Cu, Zn and Pb in shells of two benthic foraminifera species with different shell types from two shallow coastal stations in Israel: An area adjacent to an electrical power plant and desalination factory (Hadera) and an industrially free nature reserve (Nachsholim). Records of both foraminifera species show elevated metal concentrations in Hadera clearly identifying the footprint of the local industrial facilities. Moreover, short term events of elevated Cu and Pb concentrations were detected by single chamber analyses. This study demonstrates the potential of using heavy metals anomalies in foraminiferal single chambers as a tool for detecting the industrial footprint of coastal facilities as well as short term events of elevated heavy metals. PMID- 29571414 TI - The relationship between metal concentrations in seagrass (Zostera capricorni) tissue and ambient fine sediment in modified and near-pristine estuaries (Sydney estuaries, Australia). AB - Seagrass (Zostera capricorni) tissue metal concentrations in Sydney estuary are some of the highest reported for urban environments. A strong declining metal (As, Co, Cr, Cu, Mn, Pb and Zn) concentration gradient in fine sediment from highly modified to the near-pristine estuarine environments was matched by a concurrent and statistically significant, moderately strong, relationship with declining metal concentrations for leaf, rhizomes and root tissue types. Leaf tissue more consistently expressed metal concentration uptake from sediment. Rhizome tissue contained the highest concentrations for all metals, except Mn, while leaf concentrations were higher for Cr and Zn and roots were more elevated in Cr and Pb. Tissue Cr, Pb and Zn were close to background for reference sites for leaves. Maximum tissue enrichment over background was 25, 19, 47 and 8 times for Cr, Cu, Pb and Zn. Bio-sediment accumulation factors were generally <1 for all metals. PMID- 29571415 TI - Distribution and metal contamination in the coastal sediments of Dammam Al-Jubail area, Arabian Gulf, Saudi Arabia. AB - Present work aims to document the distribution and metal contamination in the coastal sediments of the Dammam Al-Jubail area, Saudi Arabian Gulf. Twenty-six samples were collected for Al, V, Cr, Mn, Cu, Zn, Cd, Pb, Hg, Sr, As, Fe, Co and Ni analysis. Results of enrichment factor indicated that Sr, Cd, Cu, Hg, V, As, Ni, Cr and Zn gave enrichment factors higher than 2 (98.87, 40.28, 33.20, 27.87, 26.11, 14.10, 6.15, 3.72 and 2.62 respectively) implying anthropogenic sources, while Pb, Mn and Al have very low background level (1.37, 0.71, 0.124 respectively), probably originated from natural sources. Average concentrations of Sr, V, Hg, Cd and As were mostly higher than those from the background shale and the earth crust, the Caspian Sea, the Mediterranean Sea, the sediment quality guidelines, the Red Sea, the Gulf of Aqaba and the Gulf of Oman. The higher levels of the studied metals are mostly related samples with high Al and TOM content, as well as the visible anthropogenic pollutants along the studied coastline. The most recorded anthropogenic pollutants were sewage effluent, landfilling due to coastal infrastructure development, oil spills, petrochemical industries and desalination plants in Al-Jubail industrial city. PMID- 29571416 TI - The underwater acoustic environment at SGaan Kinghlas-Bowie Seamount Marine Protected Area: Characterizing vessel traffic and associated noise using satellite AIS and acoustic datasets. AB - Vessel traffic is one of the most wide-spread anthropogenic contributors to ocean noise worldwide and has the potential to alter ecosystems upon which cetaceans and other acoustically sensitive marine organisms rely. Canada's SGaan Kinghlas Bowie Seamount Marine Protected Area (SK-B MPA) is one such area whose productive ecosystem could benefit from greater monitoring of human induced threats in order to inform management. Despite earning official designation as a Marine Protected Area under the Oceans Act in 2008, little remains known about vessel traffic in the region and the associated potential impacts on vulnerable marine species. Therefore, to increase our understanding of vessel traffic and accompanying noise at SK-B MPA, satellite AIS and acoustic data were investigated. The results of this study suggest that variations in ambient sound levels in the region are driven by near and distant shipping events, thus having implications for future management of the MPA. PMID- 29571417 TI - Ingestion of microplastics and natural fibres in Sardina pilchardus (Walbaum, 1792) and Engraulis encrasicolus (Linnaeus, 1758) along the Spanish Mediterranean coast. AB - The ingestion of microplastics and natural fibres (<5 mm) was assessed for two commercial fish species in the western Mediterranean Sea: Sardina pilchardus and Engraulis encrasicolus. Gastrointestinal tracts from 210 individuals from 14 stations were examined with 14.28-15.24% of the small pelagic fish S. pilchardus and E. encrasicolus having ingested microplastics and natural fibres. A latitudinal increase in condition index (Fulton's K) of S. pilchardus gave an indication that larger individuals with better physical condition are less likely to ingest microplastics and natural fibres. Fibres were the most frequent particle type (83%) and Fourier Transform Infrared spectroscopy (FT-IR) analysis indicated polyethylene terephthalate was the most common microplastics material (30%). Results from this study show that both microplastics and natural fibres of anthropogenic origin are common throughout the pelagic environment along the Spanish Mediterranean coast. PMID- 29571419 TI - Women and Peripheral Arterial Disease: A Review of Sex Differences in Epidemiology, Clinical Manifestations, and Outcomes. AB - Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in women. Peripheral arterial disease (PAD), a manifestation of CVD and a marker for other adverse CVD outcomes such as ischemic heart disease and stroke, remains underrecognized and undertreated in women. Contrary to the previous belief that PAD is mainly a disease of white men, contemporary data suggest equal, if not higher, prevalence rates in nonwhite women. Women often present with asymptomatic or atypical disease and seek medical attention with more advanced disease. Cardiovascular morbidity and mortality rates, as well as procedural mortality rates, remain elevated in women compared with men. There are sex-specific markers and comorbidities with a higher female prevalence that are associated with PAD. Greater focus on PAD in cardiovascular trials, equivalent enrollment of women in large trials, and focused prevention strategies may help reduce the economic burden and adverse outcomes associated with PAD in women. PMID- 29571418 TI - Mapping elemental contamination on Palmyra Atoll National Wildlife Refuge. AB - Palmyra Atoll, once a WWII U.S. Navy air station, is now a U.S. National Wildlife Refuge with nearly 50km2 of coral reef and 275ha of emergent lands with forests of Pisonia grandis trees and colonies of several bird species. Due to the known elemental and organic contamination from chemicals associated with aviation, power generation and transmission, waste management, and other air station activities, a screening survey to map elemental concentrations was conducted. A map of 1944 Navy facilities was georeferenced and identifiable features were digitized. These data informed a targeted survey of 25 elements in soils and sediment at locations known or suspected to be contaminated, using a hand-held X ray fluorescence spectrometer. At dozens of locations, concentrations of elements exceeded established soil and marine sediment thresholds for adverse ecological effects. Results were compiled into a publically available geospatial dataset to inform potential remediation and habitat restoration activities. PMID- 29571420 TI - Sex Considerations in Aneurysm Formation, Progression, and Outcomes. AB - Aneurysm formation is a complex multifactorial process with both genetic and environmental influences. Over recent years, there has been increasing recognition of sex-specific differences regarding the prevalence and natural history of cardiovascular diseases in the population. In particular, there is a growing body of evidence showing that aneurysm behaviour differs based on sex. Although most types of aneurysms are more common in men, their growth rates and outcomes are worse in women. This fact raises attention about potential underlying differences in the arteries of men and women that may contribute to differences in aneurysm prevalence and outcomes. There are complex biochemical and mechanical mechanisms at play that contribute to vascular health. Furthermore, many studies have suggested potential differences in the hormonal milieu and underlying arterial anatomy between men and women. Based on the data reviewed in this article, assessment of the underlying pathophysiology of aneurysms in women might prove clinically useful regarding prevention, early detection, and management of aneurysms in women. Sex-specific research, screening, and treatment guidelines for aneurysm disease should be introduced to reflect the differing natural history of these diseases in men and women. PMID- 29571421 TI - Mechanisms and Clinical Significance of Endothelial Dysfunction in High-Risk Pregnancies. AB - The maternal cardiovascular system undergoes critical anatomic and functional adaptations to achieve a successful pregnancy outcome which, if disrupted, can result in complications that significantly affect maternal and fetal health. Complications that involve the maternal cardiovascular system are among the most common disorders of pregnancy, including gestational hypertension, preeclampsia, gestational diabetes, and impaired fetal growth. As a central feature, maternal endothelial dysfunction is hypothesized to play a predominant role in mediating the pathogenesis of these high-risk pregnancies, and as such, might proceed and precipitate the clinical presentation of these pregnancy disorders. Improving or normalizing maternal endothelial function in high-risk pregnancies might be an effective therapeutic strategy to ameliorate maternal and fetal clinical outcomes. PMID- 29571422 TI - Atherosclerotic Heart Disease in Women With Autoimmune Rheumatologic Inflammatory Conditions. AB - Women have a higher prevalence of several inflammatory rheumatologic conditions. These include systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic sclerosis (SSc) to name a few. These conditions are all associated with higher rates of cardiovascular (CV) morbidity and mortality, which is driven primarily by atherosclerotic heart disease. Traditional risk factors are important considerations in the assessment of CV risk in the rheumatologic patient; however, these factors do not appear to impart a similar weight of risk in women with inflammatory autoimmune rheumatologic conditions. In addition, even when controlling for traditional risk factors, patients with RA or SLE continue to have a higher risk of CV events, which has been linked to the burden of systemic inflammation. Currently, the CV risk scoring systems available for the general population underestimate the burden of the problem in these complex patients. The increased CV risk in patients with rheumatologic diseases has been reported in the literature for years but remains underrecognized by internists and cardiologists. Although these conditions themselves are relatively rare, the further study of inflammation and its treatment in CV disease will be beneficial to the general population. PMID- 29571423 TI - Recent Developments in Sex-Related Differences in Presentation, Prognosis, and Management of Coronary Artery Disease. AB - Coronary artery disease (CAD) is the most prevalent type of heart disease among women and men. Sex-related differences in the presentation, prognosis, and management of patients with CAD has been increasingly studied. Compared with men, women are more likely to present with multiple comorbidities, have a higher prevalence of psychological risk factors, and present with atypical symptoms. These factors, along with delays in seeking medical attention, might contribute to sex-related treatment differences in women with stable angina and acute coronary syndrome. This review article highlights recent evidence examining sex related differences in stable CAD patients with obstructive CAD, nonobstructive CAD, as well as myocardial infarction. PMID- 29571424 TI - Optimizing Risk Stratification and Noninvasive Diagnosis of Ischemic Heart Disease in Women. AB - Ischemic heart disease (IHD) is an important and previously underappreciated cause of significant morbidity and mortality in women. Key differences exist in the pathophysiology, sex-specific risk factors, and clinical presentation in women compared with men, which influence diagnostic accuracy and utility of pretest risk assessments and noninvasive testing. Women are disproportionately affected by ischemia from microvascular dysfunction as evidenced by having less obstructive coronary artery disease on angiography, contributing to the challenge in diagnosis and prognosis of IHD in women via conventional methods, which tend to emphasize detection of epicardial stenoses. In this article, we review the utility, evidence for, and challenges of currently available risk assessments and noninvasive cardiac diagnostic tests in women. We propose an approach to investigation of the symptomatic woman with suspected IHD and selection of the appropriate testing modality. Finally, we explore opportunities for future research and highlight the urgent need for updated, evidence-based, Canadian guidelines specific to women with IHD. PMID- 29571425 TI - Coronary Surgery in Women and the Challenges We Face. AB - This review was undertaken to understand the dynamics that have shaped our current treatment of women who undergo coronary artery bypass grafting (CABG) and summarize the current literature on surgical revascularization in women. There has been improved access to CABG over the past several decades. Despite this, compared with men, CABG in women involves fewer grafts and less frequent use of arterial grafts, the latter having improved long-term patency compared with saphenous vein grafts. We attempt to determine whether the adverse clinical profile of women, when referred for CABG is responsible for this finding. Female coronary anatomy and pathophysiology are reviewed and an attempt is made to understand how this might affect decisions of selection and outcome measures post CABG. We review the short-term, long-term, and quality of life outcomes in women. These data are taken from large databases, as well as from more recent publications. Randomized controlled trial data and meta-analytic data are used when available. Differential use of and outcomes of surgical strategies, including off-pump CABG and total arterial revascularization, are contrasted with those in men. This review shows that there continues to be widespread differences in surgical approach to coronary artery disease in female vs male patients. We provide evidence suggestive of the existence of issues specific to women that affect selection for surgical procedures and outcomes in women. More work is required to understand the reason for these differences and how to optimize sex specific outcomes. PMID- 29571426 TI - Cardiovascular Disease Among Women From Vulnerable Populations: A Review. AB - On a global scale, cardiovascular disease (CVD) is the leading cause of mortality. It is also the number 1 cause of death among women, resulting in 8.6 million deaths annually and constituting one third of all deaths in women worldwide. The burden of CVD and related risk factors has taken priority in the policy development for noncommunicable diseases. However, vulnerable populations, defined here as women who are socially or economically disadvantaged (eg, low income), nonwhite (specifically South Asian and indigenous women), and those who are elderly have often been overlooked in these discussions. These additional vulnerabilities, which may exist independently or in combination, place such women at higher risk for CVD. Specifically, these vulnerabilities include low socioeconomic status, a low sense of control, high stress, South Asian or indigenous ancestry, and increased age. Thus it is vital that we initiate a multipronged approach to CVD prevention that includes rigorous monitoring of CVD risk factors in high-risk populations and the implementation of timely, accurate, and contextually tailored prevention programs, services, and treatments. Well trained nonphysician health care workers can support the accurate monitoring and management of CVD and CVD risk factors so that groups of women who may otherwise be overlooked can receive adequate attention. PMID- 29571427 TI - Myocardial Infarction With No Obstructive Coronary Artery Disease: Angiographic and Clinical Insights in Patients With Premature Presentation. AB - BACKGROUND: Premature myocardial infarction (MI) is an increasingly prevalent cause of morbidity and mortality worldwide. A subset of patients, predominantly young women, present with MI with no obstructive coronary artery disease (MINOCA), a nomenclature gaining recognition. However, few data exist on presentation and prognosis according to the severity of coronary artery disease (CAD). METHODS: We studied patients with premature (younger than 55 years of age) acute MI enrolled in a large cohort in 24 centres across Canada. Baseline clinical, psychosocial, and coronary anatomy characteristics as well as 12-month outcomes were compared between patients with MINOCA (< 50% stenosis) and patients with MI with obstructive CAD (>= 50% stenosis; MICAD). RESULTS: From a cohort of 1210 patients with acute coronary syndrome, we examined 998 MI patients with available angiography core lab readings: 82 (8.2%) had a MINOCA and 916 (91.8%) had a MICAD. Forty percent of patients with MINOCA were women compared with one third with MICAD. The prevalence of traditional risk factors and chest pain at presentation was lower in MINOCA patients, yet 37% had a ST-elevation MI and 10% presented with a cardiac arrest. No evident etiology was detected in > 70% of MINOCA, but 10% presented with either spontaneous coronary dissection or Takotsubo cardiomyopathy. Although combined major adverse cardiovascular events and all-cause readmission rate was lower in the MINOCA group (14% vs 25%; adjusted hazard ratio, 0.51; 95% confidence interval, 0.28-0.93), it was not negligible. CONCLUSIONS: Patients with MINOCA present with high-risk features despite the absence of obstructive CAD. A search for etiology and eventual treatment provides a rich avenue for improving prognosis in young women with premature MI. PMID- 29571428 TI - Sex Differences in Left Ventricular Cavity Dilation and Outcomes in Acute Heart Failure Patients With Left Ventricular Systolic Dysfunction. AB - BACKGROUND: In this study we evaluated the influence of sex on the left ventricular end-diastolic dimension (LVEDD) and adverse outcomes in patients hospitalized for acute decompensated heart failure (HF) with a reduced ejection fraction (EF). METHODS: Among the 4842 patients enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, 2367 patients (1607 men and 760 women) discharged alive after hospitalization for acute decompensated HF with a reduced EF (defined as a left ventricular EF < 50%) were investigated to assess the association of sex and LVEDD with the primary end point (all-cause death and readmission for HF after discharge). Men and women were separately divided into LVEDD quartiles at discharge (men: LVEDD <= 54, 55-60, 61-65, and >= 66 mm; women: LVEDD <= 48, 49-54, 55-60, and >= 61 mm). The median follow-up period after discharge was 524 (range, 385-785) days. RESULTS: Occurrence of the primary end point did not differ between men and women (37.0% vs 37.2%; P = 0.921). After adjustment for multiple comorbidities including left ventricular EF, men with an LVEDD of 61-65 and >= 66 mm had a significantly higher risk of the primary end point than men with an LVEDD <= 54 mm, indicating a positive association between a larger LVEDD and adverse outcomes. In contrast, in women, the adjusted risk of the primary end point was comparable among the LVEDD quartiles. CONCLUSIONS: Men and women with acute decompensated HF and a reduced EF might show important differences in relation to the association between left ventricular cavity dilation and outcomes. PMID- 29571429 TI - Maternal Physical Activity Is Associated With Improved Blood Pressure Regulation During Late Pregnancy. AB - BACKGROUND: Cardiovagal baroreflex gain (cBRG) reflects an individual's ability to buffer swings in blood pressure. It is not well understood how this mechanism is influenced by physical activity in pregnancy. Because pregnant women tend to engage in low levels of moderate-to-vigorous physical activity (MVPA) and high levels of sedentary behaviour, we sought to determine the influence of MVPA and sedentary behaviour on cBRG and mean arterial pressure (MAP) in pregnancy. METHODS: Fifty-eight third trimester (31.9 +/- 3.0 weeks) normotensive pregnant women (31.2 +/- 2.8 years) were tested. Heart rate (electrocardiogram) and blood pressure (systolic blood pressure and MAP; finger photoplethysmography) were collected on a beat-by-beat basis, and averaged over 3 minutes of rest. Spontaneous cBRG was calculated as the slope of the relationship between fluctuations in systolic blood pressure and heart rate. Objective measures of MVPA and sedentary behaviour were collected over a 7-day period using an ActiGraph accelerometer (model wGTX3-BT; ActiGraph LLC, Pensacola, FL). RESULTS: Participants spent 67.5 +/- 7.9% of waking hours engaged in sedentary behaviour, and performed 68.6 +/- 91.9 minutes of MVPA per week. Sedentary behaviour was not related to cBRG (r = -0.035; P = 0.793) or MAP (r = -0.033; P = 0.803). However, MVPA was positively associated with cBRG (r = 0.315; P = 0.016), but not MAP (r = -0.115; P = 0.389). The association between MVPA and cBRG remained significant after controlling for age, pre-pregnancy body mass index, gestational age, and wear time (r = 0.338; P = 0.013), indicating that women who engaged in greater amounts of MVPA showed increased cBRG. CONCLUSIONS: Our data suggest that increased MVPA, but not necessarily reduced sedentary behaviour, might be beneficial for reflex control of blood pressure during pregnancy.

IFN gamma, however, converts MSC into a cell therapy that can be immunogenic, detrimental, and hence nonfeasible for clinical application. The article by Bai et al. is an in vivo proof-of-concept study that interleukin-17A (IL-17A) enhances the immunosuppressive, tolerance-promoting, and renoprotective properties of MSC. IL-17A is an alternative cytokine to preactivate MSC. IL-17A enhances the therapeutic efficacy of MSC for renal diseases.

Atypical chemokine receptors regulate chemokine gradients, thereby limiting inflammation. In this issue of Kidney International, atypical chemokine receptor 2 knockouts were described to be increasingly susceptible to immune complex-mediated glomerulonephritis. By degrading CCL2, atypical chemokine receptor 2 limited the recruitment of immune cells and myofibroblasts to the renal interstitial compartment. Therefore, not only inflammation, but also fibrosis, was effectively inhibited, making atypical chemokine receptor 2 an attractive therapeutic target in glomerulonephritis.

AB - In this population study salt intake is not associated with development of chronic kidney disease (CKD) in individuals with normal blood pressure, whereas in hypertensive individuals both low and high salt intakes are associated with increased incidence of CKD, similar to U-shaped associations between salt intake and mortality found in previous studies. The results contribute to the skepticism, which has questioned the present public health policy to reduce salt intake below 5.8 g.

These observations provide the necessary stimulus to continue the development of renal blood oxygenation level-dependent magnetic resonance imaging to further improve the sensitivity and specificity to renal oxygenation and hence the predictive power.

AB - Sudden death in patients on hemodialysis is believed to be due to arrhythmia, but the evidence for this is surprisingly limited. Five studies involving implantable loop recorders in patients on hemodialysis have now been published, and 4 have shown that bradyarrhythmia rather than tachyarrhythmia are the pre-eminent arrhythmic associations of fatal events.

Firstly, the QS inhibition of hexanal was verified by significantly inhibiting violacein production (p < 0.05) in Chromobacterium violaceum CV026 at sub-MICs. beta Galactosidase activities which reflected AHL production, were significantly inhibited by hexanal, its inhibitory effect was concentration-dependent under minimal inhibitory concentration (MIC) (p < 0.05). The detected extracellular enzymes activities decreased with the increase of hexanal concentration (p < 0.05), including cellulase, xylanase, pectate lyase, polygalacturonase, and protease. Chinese cabbage soft rot and lettuce leaf scorch could be significantly inhibited by hexanal (p < 0.05) without any phytotoxicity effect, the 1/2 MIC of hexanal showed the best inhibitory effect. And all the above effects showed a dose-dependent. A novel preservation technique in reducing the loss of vegetables due to spoilage based on the QS inhibitor was developed.

AB - Nanozyme-based electrochemical sensors have attracted much attention because of their low cost, sensitivity and remarkable stability under extensive environmental and industrial conditions. Interestingly, the physical characteristics of the nanomaterials in terms of size, shape, composition, surface area and porosity dominate the electrochemical processes at electrode surfaces. Herein, we explore nickel oxide nanoplatelets (NPs) modified screen printed electrode-based nanozyme sensors that displays high electrochemical activity including stability, sensitivity, selectivity and applicability for organophosphate pesticide (Parathion) determination. Differential pulse voltammogram of NiO-SPE in presence of parathion showed a characteristic peak current at -1.0 V (vs. Ag/AgCl). The NiO-SPE platform allows determination of parathion over the concentration range of 0.1-30 uM with a limit of detection (LOD) of 0.024 uM. The sensing platform is found to detect parathion of interferences without compromising the sensitivity of the sensor. Such interesting features offer a sensitive determination of parathion in water, urine and vegetable samples.

AB - Skates and rays are commercially important fish in South Korea, and among them, Beringraja pulchra has the highest economic value. However, the similar morphological traits among skates and rays are often exploited for seafood fraud. Here, we designed both Beringraja pulchra-specific and skate-universal primer sets, capable of detecting short sequences in the cytochrome oxidase subunit I gene, and developed highly sensitive and reliable quantitative real-time PCR (qPCR) assays to differentiate between Beringraja pulchra and other skate and ray species. ADeltaCq method based on differences in the amplification efficiency was developed, validated, and then used to confirm the presence of Beringraja pulchra in twenty-six commercial skate products. The averageDeltaCq value obtained for other skate species (18.94 +/- 3.46) was significantly higher than that of Beringraja pulchra (1.18 +/- 0.15). For on-site applications, we developed an ultra-fast qPCR assay, allowing for completion of the entire analytical procedure within 30 min. PMID- 29571457 TI - A multi-methodological approach in the study of Italian PDO "Cornetto di Pontecorvo" red sweet pepper. AB - A multi-methodological approach was applied to study red sweet peppers (Capsicum annuum L.) ecotype "Cornetto di Pontecorvo" grown in a greenhouse or in open field. This approach includes morphological analysis, chemical composition determination, and biological activity evaluation of different extracts from pepper fruits. Untargeted analyses, namely NMR spectroscopy and mass spectrometry, allowed the comprehensive pepper metabolite profile of pepper pulp, peel and seeds hydroalcoholic and organic extracts to be determined, showing the presence of sugars, organic acids, amino acids and other secondary metabolites. Targeted analyses, such as HPLC-PDA, HPLC-TLC and spectrophotometric analyses allowed polyphenols, tannins, flavonoids and pigments content to be determined. Samples quality and freshness were verified by the low content of biogenic amines and mycotoxins, as determined using HPLC-FLD and HPLC-MS, respectively. Preliminary biological results demonstrated the ability of the organic extracts to inhibit alpha-amylase, a key enzyme in the control of glucose metabolism. PMID- 29571458 TI - Quantitative assessment of specific defects in roasted ground coffee via infrared photoacoustic spectroscopy. AB - Chemical analyses and sensory evaluation are the most applied methods for quality control of roasted and ground coffee (RG). However, faster alternatives would be highly valuable. Here, we applied infrared-photoacoustic spectroscopy (FTIR-PAS) on RG powder. Mixtures of specific defective beans were blended with healthy (defect-free) Coffea arabica and Coffea canephora bases in specific ratios, forming different classes of blends. Principal Component Analysis allowed predicting the amount/fraction and nature of the defects in blends while partial Least Squares Discriminant Analysis revealed similarities between blends (=samples). A successful predictive model was obtained using six classes of blends. The model could classify 100% of the samples into four classes. The specificities were higher than 0.9. Application of FTIR-PAS on RG coffee to characterize and classify blends has shown to be an accurate, easy, quick and "green" alternative to current methods. PMID- 29571459 TI - Development of 87Sr/86Sr maps as targeted strategy to support wine quality. AB - This study summarizes the results obtained from a systematic and long-term project aimed at the development of tools to assess the provenance of food in the oenological sector. In particular, 87Sr/86Sr isotope ratios were measured on statistically representative set of soils, vine branches and wines sampled in the production district of Modena, worldwide known for the Lambrusco wines production. The obtained data were used to build strontium isotopic maps able to objectively support the Lambrusco PDO wines origin as well as other products of the Modena district. Finally, a strong relationship was found between the 87Sr/86Sr isotope ratios of soils and vine branches on a large scale, highlighting and confirming once more the idea that plants can also represent an optimal sampling device to support geographical traceability. PMID- 29571460 TI - Analysis of functional components and radical scavenging activity of 21 algae species collected from the Japanese coast. AB - The functional chemical substances and the antioxidant activity of lipids in 21 marine algae along the Japanese coast were investigated. Principal component analysis was performed to detect any correlation between the chemical substances and algae phylum. Chlorophyta contained a high level of beta-carotene. Rhodophyta contained high amounts of cholesterol, beta-sitosterol, and saturated fatty acids. Phaeophyta were rich in fucosterol, alpha-tocopherol, fucoxanthin, and polyphenol. Phaeophyta algae also showed the highest antioxidant activity compared with other phylum. This suggests that Phaeophyta has the greatest potential to be used as a functional food. Consumption of the beneficial Phaeophyta species, such as Eisenia arborea Areschoug and Ecklonia cava Kjellman should be encouraged as not only as food products but also as nutraceuticals and dietary supplements. These beneficial ingredients should be encouraged to be studied in depth with the possibility to develop specific formulated products target to special consumer's population with added nutritional value. PMID- 29571461 TI - Heavy metal contamination in soil, food crops and associated health risks for residents of Ropar wetland, Punjab, India and its environs. AB - In the present study, an assessment of heavy metal content in soil and food crops (wheat, rice, maize grains and mustard seeds) and associated health risks was carried out for residents of Ropar wetland and its environs. All the soil samples had high cadmium and cobalt contents, whereas, all crop samples had high contents of cobalt and lead. Bioconcentration factor (BCF) analysis indicated that rice grains act as hyper-accumulators of chromium (BCF = 17.98) and copper (BCF = 10.91), whereas, maize grains act as hyper-accumulators of copper (BCF = 30.43). One-way ANOVA suggested that heavy metal content in food crops varied significantly at p <= 0.05 for different sites, indicating anthropogenic contribution of heavy metals in agricultural fields. Dietary intake of cobalt via all food crops posed higher non-cancer health risk to residents in comparison to other heavy metals. Chromium posed highest cancer risk through consumption of wheat grains, being staple diet in study area. PMID- 29571462 TI - Kinetics, biocompounds, antioxidant activity, and sensory attributes of quinces as affected by drying method. AB - Quinces are attracting interest due to their health and nutritional benefits. Drying kinetics, bioactive compounds, antioxidant activity, and the main sensory parameters were determined in dried quinces, cultivar Leskovac, as affected by the drying method. The highest total polyphenols content was observed in dried samples obtained after freeze drying and convective drying at 50 degrees C. The best drying treatment, considering only sensory attributes, was vacuum-microwave drying at 480 W, because it led to intermediate dark color and high intensities of basic tastes and key flavor attributes. The studied parameters were finally used to recommend convective drying at 60 degrees C as the most appropriate drying method for quinces, because it had a high content of total phenolic compounds (2nd best treatment out of 10), a good sensory profile, was cheap, and caused no negative effects on nutritional or sensory parameters; the only disadvantage was its long drying time. PMID- 29571463 TI - The taste of KCl - What a difference a sugar makes. AB - Dramatic increase in NaCl consumption lead to sodium intake beyond health guidelines. KCl substitution helps reduce sodium intake but results in a bitter metallic off-taste. Two disaccharides, trehalose and sucrose, were tested in order to untangle the chemical (increase in effective concentration of KCl due to sugar addition) from the sensory effects. The bitter-metallic taste of KCl was reduced by these sugars, while saltiness was enhanced or unaltered. The perceived sweetness of sugar, regardless of its type and concentration, was an important factor in KCl taste modulation. Though KCl was previously shown to increase the chemical activity of trehalose but not of sucrose, we found that it suppressed the perceived sweetness of both sugars. Therefore, sensory integration was the dominant factor in the tested KCl-sugar combinations. PMID- 29571464 TI - The roles of bacteria in the biochemical changes of chill-stored bighead carp (Aristichthys nobilis): Proteins degradation, biogenic amines accumulation, volatiles production, and nucleotides catabolism. AB - This study investigated the biochemical changes (proteins degradation, total volatile basic nitrogen, biogenic amines, volatile organic compounds, nucleotides catabolism and related enzymes) of bighead carp samples inoculated with four different bacteria (Shewanella putrefaciens, Aeromonas sobria, Acinetobacter bohemicus, and Pseudomonas helmanticensis) during storage at 4 +/- 1 degrees C. A. sobria exhibited the strongest proteolytic activity. A. sobria, P. helmanticensis, and S. putrefaciens were responsible for putrescine production, whereas S. putrefaciens was the sole producer of cadaverine. Alcohols and S compounds were mainly released by A. sobria and S. putrefaciens, respectively. The fastest degradation rates of hypoxanthine riboside and hypoxanthine were found in samples inoculated with P. helmanticensis and S. putrefaciens. Inosine nucleosidase was mainly resulted by A. sobria, P. helmanticensis and S. putrefaciens, whereas xanthine oxidase was derived from both fish muscle and secretions of P. helmanticensis and S. putrefaciens. PMID- 29571465 TI - Validation of an analytical method for the quantitative determination of selenium in bacterial biomass by ultraviolet-visible spectrophotometry. AB - The present paper describes the validation of a spectrophotometry method involving molecular absorption in the visible ultraviolet-visible (UV-Vis) region for selenium (Se) determination in the bacterial biomass produced by lactic acid bacteria (LAB). The method was found to be suitable for the target application and presented a linearity range from 0.025 to 0.250 mg/L Se. The angular and linear coefficients of the linear equation were 1.0678 and 0.0197 mg/L Se, respectively, and the linear correlation coefficient (R2) was 0.9991. Analyte recovery exceeded 96% with a relative standard deviation (RSD) below 3%. The Se contents in LAB ranged from 0.01 to 20 mg/g. The Se contents in the bacterial biomass determined by UV-Vis were not significantly different (p > 0.05) those determined by graphite furnace atomic absorption spectrometry. Thus, Se can be quantified in LAB biomass using this relatively simpler technique. PMID- 29571466 TI - Spectroscopic and docking studies on the interaction between caseins and beta carotene. AB - Natural occurrence of beta-carotene in bovine milk and the leading role of milk proteins in low-fat or fat-free dairy products necessitate investigating the possibility of interaction between beta-carotene and casein constituting up to 80% of bovine milk proteins. In this study, molecular interaction of caseins and beta-carotene was analyzed using fluorescence, UV-Vis absorption, circular dichroism (CD), and computer-aided molecular modeling. Casein and its fractions were bound to beta-carotene with a binding constant of the order 104 M-1 and a 1:1 binding stoichiometry. The binding was favored at alkaline pHs, low ionic strength and temperatures. kappa-Casein had the highest binding affinity to beta carotene, among casein fractions. The negative values of entropy and enthalpy changes and docking studies proved Van der Waals interactions are predominant forces in the binding process. The casein conformation was also altered through inducing a more folded structure in beta-casein and a looser conformation in alpha- and kappa-casein. PMID- 29571467 TI - The potential of kiwifruit puree as a clean label ingredient to stabilize high pressure pasteurized cloudy apple juice during storage. AB - In the fruit juice industry, high pressure (HP) processing has become a commercial success. However, enzymatic browning, cloud loss, and flavor changes during storage remain challenges. The aim of this study is to combine kiwifruit puree and HP pasteurization (600 MPa/3 min) to stabilize cloudy apple juice during storage at 4 degrees C. A wide range of targeted and untargeted quality characteristics was evaluated using a multivariate approach. Due to high ascorbic acid content and high viscosity, kiwifruit puree allowed to prevent enzymatic browning and phase separation of an apple-kiwifruit mixed juice. Besides, no clear changes in organic acids, viscosity, and particle size distribution were detected in mixed juice during storage. Sucrose of apple and mixed juices decreased with glucose and fructose increasing during storage. The volatile changes of both juices behaved similar, mainly esters being degraded. Sensory evaluation demonstrated consumer preferred the aroma of mixed juice compared to apple juice. PMID- 29571468 TI - pH-Dependency of the proteolytic formation of cocoa- and nutty-specific aroma precursors. AB - Sensory evaluation of roasted cocoa not only revealed cocoa-specific but also more or less pronounced nutty-specific aroma notes. Essential precursors of the corresponding volatile compounds could be generated in vitro by proteolysis of the cocoa vicilin-class(7S) globulin using a mixture of cocoa aspartic protease and cocoa carboxypeptidase. Since both proteases have rather different pH optima (pH 3.5 and 5.5-6.0, respectively), we have investigated the pH-dependency of proteolysis of this protein substrate in the presence of both proteases, the liberation of free amino acids and the generated aroma potential. Our findings revealed that the precursors of the nutty aroma notes were generated at higher pH values (pH 4.8-5.6) than the cocoa-specific precursor peptides (pH 4.4-5.2). Longer peptide fragments of the cocoa vicilin were formed by proteolysis at pH 5.2 than at pH 4.8. Furthermore, our findings indicated that cocoa-vicilin derived peptides are essential precursors of both the cocoa- and the nutty specific aroma components. PMID- 29571469 TI - Physicochemical and emulsification properties of flaxseed (Linum usitatissimum) albumin and globulin fractions. AB - The physicochemical and emulsification characteristics of flaxseed albumin and globulin protein fractions were determined in this study. Flaxseed protein meal was extracted with 0.5 M NaCl, and the extract dialyzed against water followed by centrifugation to obtain the globulin as a water-insoluble precipitate and albumin as the water-soluble albumin. Gel electrophoresis data indicate that the globulin is composed of several polypeptides in the 10-50 kDa range while albumin consisted mainly of the 10 kDa polypeptide accompanied by a minor content of 40 kDa. Amino acid analysis showed significantly (p < 0.05) higher levels of hydrophobic amino acids in the globulin, which was consistent with higher surface hydrophobicity when compared to the albumin. All the emulsions had monomodal oil droplet size distribution and wider ranges were directly related to bigger sizes, especially at low (10 mg/mL) protein concentration when compared to the 50 mg/mL. PMID- 29571470 TI - Magnetic molecular imprinting polymers based on three-dimensional (3D) graphene carbon nanotube hybrid composites for analysis of melamine in milk powder. AB - A novel analytical method for melamine in milk powder has been developed and exploited with three-dimensional (3D) magnetic molecularly imprinted polymers (MMIPs) combining with liquid chromatography-tandem mass spectrometry. The 3D MMIPs were synthesized with graphene-carbon nanotube hybrid composite as carrier which can increase the accessible surface area. The products were characterized, and the binding affinity was investigated by isothermal absorption, kinetic adsorption and selective adsorption. The results showed that the 3D MMIPs exhibited high adsorption capacity with maximum adsorption capacity of 123.1 mg g 1, fast adsorption rate (10 min) and high selectivity toward melamine. Various affecting extraction parameters were evaluated. The limit of detection was 0.00045 mg kg-1 and the recoveries were ranged from 90.3% to 95.7%. The precisions (RSDs) were lower than 4.7%. This method was applied for analyzing six milk powder samples. The result was in agreement with that obtained by the state standard method used in China. PMID- 29571471 TI - Persimmon vinegar polyphenols protect against hydrogen peroxide-induced cellular oxidative stress via Nrf2 signalling pathway. AB - Since polyphenols are known to exhibit antioxidative properties, we prepared and characterized persimmon vinegar polyphenols (PVP) in this study. Furthermore, we investigated the protective effect of PVP on hydrogen peroxide (H2O2)-induced oxidative stress in HepG2 cells and its underlying mechanisms. Our results showed that flavon-3-ols were the predominant polyphenols in PVP. Pre-treatment with PVP significantly decreased (p < 0.05) H2O2-induced cell damage in a dose-dependent manner, accompanied by decrease in lactate dehydrogenase (LDH) leakage, aminotransferase activities, and ROS accumulation. Moreover, PVP upregulated the expression of antioxidative enzymes, such as heme oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase 1 (NQO1), and increased the levels of glutathione. Western blotting results showed that PVP induced the nuclear translocation of nuclear factor (erythroid-derived-2)-related factor 2 (Nrf2). Taken together, our results indicated that PVP effectively protected HepG2 cells against oxidative stress via activation of the Nrf2 antioxidative pathway. PMID- 29571472 TI - Determination of ppq-levels of alkylmethoxypyrazines in wine by stirbar sorptive extraction combined with multidimensional gas chromatography-mass spectrometry. AB - Alkylmethoxypyrazines are powerful odorants in many food products. A new method for analysing 3-isopropyl-2-methoxypyrazine, 3-s-butyl-2-methoxypyrazine and 3 isobutyl-2-methoxypyrazine has been developed and applied to wine. The analytes were extracted from 5 mL of wine using stirbar sorptive extraction followed by thermal desorption and multidimensional gas chromatography-mass spectrometry analysis in a single oven. The extraction conditions were optimized in order to obtain a high recovery of the 3-alkyl-2-methoxypyrazines (MP). The detection limits of the method in all cases were under 0.08 ng/L, well below the olfactory thresholds of these compounds in wine. The reproducibility of the method was adequate (below 10%), the linearity satisfactory and the recoveries in all cases close to 100%. The method has been applied to the analysis of 111 Spanish and French wine samples. The levels found suggest that MP have a low direct impact on the aroma properties of wines from the regions around the Pyrenean massif. PMID- 29571473 TI - Heat-induced polymerization behavior variation of frozen-stored gluten. AB - The current study comparatively investigated the heat-induced polymerization behavior of fresh and frozen-stored gluten to replenish the gluten deterioration mechanism in frozen dough from the perspective of subsequent polymerization behavior during heating. The results showed that disulfide-mediated polymerization of frozen-stored gluten upon heating at 95 degrees C was suppressed. The polymerization ability of glutenin was weakened rather than gliadin for frozen-stored gluten. Enhanced level of beta-structures at the expense of alpha-helices was detected during the incipient heating of fresh gluten, while converse trend was noticed for the frozen-stored gluten. Frozen stored gluten exhibited less exposure of surface hydrophobic groups during the initial heating, suggesting that it was less responsive to the unfolding process. The weakened viscoelastic properties of frozen-stored gluten throughout heating protocols were mainly originated from glutenin macropolymer depolymerization as well as the hindered formation of glutenin-gliadin crosslinking and non-covalent bonds. PMID- 29571474 TI - Kinetic study on photostability of retinyl palmitate entrapped in policosanol oleogels. AB - Photostability of all-trans retinyl palmitate (RP) (100% bioactivity) was studied in policosanol oleogels (PCOs) (7-12% w/w policosanol in soybean oil) after UVA irradiation. RP was incorporated into PCOs at levels of 0.04%, 0.1% and 1% (w/w). PCOs efficiently protected RP from UVA-mediated degradation. Over 75% RP-activity remained in PCOs after 4 days of UVA irradiation, while 12% RP-activity remained in soybean oil. HPLC analysis showed that cis-RP was formed in liquid soybean oil after 2 days of UVA irradiation while it was absent in PCOs matrices. PCOs blocked the energy absorption from UVA and further dampened the UVA-mediated ionic photodissociation and free radical reaction due to matrix immobilization. For all samples, RP photodegradation followed a 2nd order reaction. From the reaction kinetics, it would be possible to predict the RP photodegradation rate in PCO matrices. PCOs were shown to be a promising matrix to protect RP from photodegradation. PMID- 29571475 TI - Gut peptidases from a specialist herbivore of latex plants are capable of milk protein hydrolysis: Inputs for hypoallergenic milk formulas. AB - Transitory allergies to cow milk proteins in infants or adults have become a public health problem. Although extensively or partially hydrolyzed cow milk protein formulas are available, these products are costly. Therefore, studies into innovative enzymes to digest cow milk proteins are needed. Danaus plexippus gut peptidases were purified and examined with regard to cow milk protein hydrolysis. The peptidases hydrolyzed caseins and whey proteins. However, after heat treatment, there was a significant improvement in beta-lactoglobulin hydrolysis. The hydrolyzed cow milk proteins were not recognized by anti-casein antibodies and only reacted slightly with antibodies against whey proteins. This performance was better than that of partially hydrolyzed formulas and similar to that of an extensively hydrolyzed formula. These results suggest that D. plexippus gut peptidases are suitable and innovative enzymes to produce hypoallergenic cow milk protein formulas. PMID- 29571476 TI - Annatto-entrapped casein-chitosan complexes improve whey color quality after acid coagulation of milk. AB - A fraction of annatto is often transferred to the whey fluid during Cheddar cheese processing, which negatively impacts the visual and sensory attributes of the resultant whey powder. Alternatives to reduce the color in the powder are still needed. In this study, casein-chitosan complexes were prepared to deliver annatto preferentially to the curd and reduce the amount of carryover colorant in whey powder. These complexes were relatively spherical, with a mean complex diameter of 8.3 +/- 1.9 um, zeta-potential of +39.4 +/- 1.3 mV, and entrapment efficiency of 38.2 +/- 3.1%. FT-IR spectroscopy confirmed the electrostatic interaction between casein and chitosan. Complexes and commercial annatto powder were incorporated into homogenized, reduced-fat, and fat-free milk, and subjected to acid coagulation. Whey powder produced from casein-chitosan-complex-treated samples exhibited better color quality than that prepared with annatto powder, indicating that the approach considered in this study was efficient in preventing the migration of colorant to the whey. PMID- 29571477 TI - Patulin accumulation in apples under dynamic controlled atmosphere storage. AB - The goal of this study was to evaluate patulin contamination in 'Galaxy' and 'Fuji Kiku' apples subjected to controlled atmosphere (CA) and dynamic controlled atmosphere (DCA) conditions. Experiments were performed and fruit were stored for nine months under refrigeration plus 7 days shelf life at 20 degrees C. CA and DCA were not effective in preventing patulin production in either 'Galaxy' or 'Fuji Kiku' apples. Healthy fruit were not contaminated with patulin, even when stored together with decayed apples. For 'Galaxy' apples, application of 1 methylcyclopropene increased the percentage of fruit with decay and patulin contamination. Patulin concentrations were above the maximum limit (50 MUg kg-1) established in the Brazilian legislation, meaning the use of CA and DCA conditions were not advantageous in preventing patulin accumulation. In 'Fuji Kiku' apples, there was no significant difference in patulin concentration among CA, DCA-CF and DCA-RQ 1.3 treatments, and all were below the maximum. PMID- 29571478 TI - Identification of a precursor of 2-mercapto-3-methyl-1-butanol in beer. AB - 2-Mercapto-3-methyl-1-butanol (2M3MB) imparts an onion-like off-flavor to beer and is believed to result from the hot aeration of brewer's wort. However, little has been reported regarding the mechanism of formation of 2M3MB. This paper investigates the precursors of 2M3MB formed during the brewing process. Our study of a cysteine conjugate as a precursor showed its negligible contribution to the formation of 2M3MB. The 2M3MB precursor was found to be a volatile compound because 2M3MB was formed in the distillate of hop extract. The precursor was purified through distillation, column chromatography, and preparative gas chromatography, and the 2M3MB-producing potential was measured as an index for estimating the concentration of the precursor. The accurate mass of the precursor was measured using gas chromatography coupled to quadrupole-time-of-flight-mass spectrometry (GC/QTOF). The molecular structure was identified from the product ion spectra by GC/QTOF to be 2,3-epoxy-3-methylbutanal. PMID- 29571479 TI - Combination of sodium caseinate and succinylated alginate improved stability of high fat fish oil-in-water emulsions. AB - Sodium caseinate (CAS) and commercial sodium alginate (CA), long chain modified alginate (LCMA) or short chain modified alginate (SCMA) were used in combination for emulsifying and stabilizing high fat (50-70%) fish oil-in-water emulsions. Physical (creaming, droplet size, viscosity and protein determination) and oxidative (primary and secondary oxidation products) stabilities of the emulsions were studied during 12 days of storage. Creaming stability was higher for emulsions produced with alginates and CAS compared to emulsions prepared with only CAS. Combined use of CAS + LCMA performed better in terms of physical stability compared to emulsions produced with only CAS. However, the oxidative stability of this emulsion was inferior probably due to the presence of an unsaturated carbon chain in LCMA structure. CAS + SCMA emulsions not only showed better physical stability such as smaller droplet size, lower creaming and higher viscosity, but also had an improved oxidative stability than emulsions produced with only CAS. PMID- 29571480 TI - Phytochemical profiles, and antimicrobial and antioxidant activities of greater galangal [Alpinia galanga (Linn.) Swartz.] flowers. AB - Previous studies of galangal (Alpinia galanga) have focussed mostly on rhizomes but seldom on flowers. A comprehensive look at galangal flowers could reveal additional benefits. The chemical composition of galangal flowers was significantly (p < 0.05) different from that of galangal rhizome. Pentadecane and alpha-humulene were identified as major compounds of galangal flower essential oil. 1'-acetoxyeugenol acetate was identified as the highest compound in flowers and exhibited the strongest antimicrobial activity among all fractions, with MIC50 values of 34 MUg/ml against Staphylococcus aureus and 68 MUg/ml against Listeria monocytogenes. Galangal flowers had a 3-fold higher total phenols content than had rhizomes (10.5 vs. 3.33 mg GAE/g powder). The antioxidant activities of different flower fractions varied from 2 to 4.45 mmol trolox/g phenolics. These findings suggest that antimicrobial and antioxidant agents extracted from galangal flowers could potentially be utilized as natural food preservatives or as therapeutic agents. PMID- 29571481 TI - Fatty acidomics: Evaluation of the effects of thermal treatments on commercial mussels through an extended characterization of their free fatty acids by liquid chromatography - Fourier transform mass spectrometry. AB - An unprecedented characterization of free fatty acids (FFA) in the lipid extracts of fresh or thermally treated mussels of sp. Mytilus galloprovincialis, including up to 128 saturated, mono- or poly-unsaturated and 63 oxidized (i.e., modified by hydroxylic, carbonylic and/or epoxylic groups) compounds, was achieved using reverse phase chromatography coupled to electrospray ionization-Fourier transform single and tandem mass spectrometry (RPC-ESI-FTMS,MS/MS). Subsequent Principal Components Analysis (PCA) evidenced several effects of thermal treatments on the mussel FFA profiles. In particular, death-inducing low temperature treatments (freezing at -16 degrees C or refrigeration at 4 degrees C for several days) induced a peculiar increase in the incidence of FFA, whereas the effect was absent in mussels undergoing death upon prolonged storage at room temperature (25 degrees C, 6 h) or fast cooking (100 degrees C, 5 min). Alive mussels, either fresh or resulting from short term (up to 48 h) refrigeration were actually indistinguishable by PCA, although subtle seasonal effects were observed. PMID- 29571482 TI - A new method of UA_CPE coupled with spectrophotometry for the faster and cost effective detection of proline in fruit juice, honey, and wine. AB - The study developed a new method for proline detection in honey, wine and fruit juice using ultrasound assisted-cloud point extraction (UA-CPE) and spectrophotometry. Initially, a quaternary complex was built, containing proline, histamine, Cu(II), and fluorescein at pH 5.5. Samples were treated with ethanol water mixture before extraction and preconcentration, using an ultrasonic bath for 10 min at 40 degrees C (40 kHz, 300 W). After the optimization of variables affecting extraction efficiency, good linearity was obtained between 15 and 600 ug L-1 with sensitivity enhancement factor of 105. The limits of detection and quantification were 5.7 and 19.0 ug L-1, respectively. The recovery percentage and relative standard deviations (RSD %) were between 95.3 and 103.3%, and 2.5 and 4.2%, respectively. The accuracy of the method was verified by the analysis of a standard reference material (SRM 2389a). PMID- 29571483 TI - Coupling laser desorption with gas chromatography and ion mobility spectrometry for improved olive oil characterisation. AB - The investigation of volatile compounds in the headspace of liquid samples can often be used for detailed and non-destructive characterisation of the sample. This has great potential for process control or the characterisation of food samples, such as olive oil. We investigated, for the first time, the plume of substances released from olive oil droplets by laser desorption in a feasibility study and applied ion mobility spectrometry coupled to rapid GC pre-separation to enhance selectivity. Our investigation demonstrated that significantly more substances can be detected and quantified via laser desorption than in the usual headspace, enabling a rapid (5-10 min), sensitive (low ng/g range) and comprehensive analysis of the sample, with the potential for quality control and fraud identification. Therefore, laser desorption provides a useful sampling tool for characterising liquids in many applications, requiring only a few uL of sample. PMID- 29571484 TI - Nitrogen compounds in Phacelia tanacetifolia Benth. honey: First time report on occurrence of (-)-5-epi-lithospermoside, uridine, adenine and xanthine in honey. AB - Lacy phacelia (Phacelia tanacetifolia Borkh.) honey composition was screened by UHPLC-DAD-QqTOF-MS. The targeted analysis revealed 6 major nitrogen compounds including aromatic amino acids (tyrosine, phenylalanine), purine derivatives (adenine, xanthine), nucleoside (uridine) and rare non-cyanogenic cyanoglucoside, (-)-5-epi-lithospermoside ((2Z)-2-[(4R,5R,6S)-4,5-dihydroxy-6-(beta-d glucopyranosyl)oxycyclohex-2-en-1-ylidene]acetonitrile). Their identity was confirmed by different analytical tools: HRMS, co-chromatography with standard compound or comprehensive NMR experiments. All the compounds, except amino acids, were reported and determined in honey for the first time. The amount of the compounds was quantified in 16 unifloral phacelia samples: adenine (18.45 +/- 4.63 mg/kg), xanthine (10.53 +/- 2.98 mg/kg), uridine (42.84 +/- 9.26 mg/kg), tyrosine (14.66 +/- 10.22 mg/kg), (-)-5-epi-lithospermoside (70.61 +/- 31.37 mg/kg) and phenylalanine (20.41 +/- 11.99 mg/kg). The (-)-5-epi-lithospermoside content is significantly correlated with P. tanacetifolia pollen percentage (R2 = 0.5612, p < 0.001) and it is proposed as a potential marker of botanical origin for phacelia honey.

AB - A method for arsenic speciation in shark, shrimp, squid, oyster and scallop using liquid chromatography coupled to inductively coupled plasma triple quadrupole mass spectrometry (LC-ICP-MS/MS) was proposed. Suitable sensitivity and selectivity by LC-ICP-MS/MS were obtained using 10 mmol L-1 (NH4)2HPO4 diluted in 1% methanol (pH 8.65) as mobile phase. Recoveries from 90 to 104% for arsenobetaine (AsB), arsenite [As(III)], dimethylarsinic acid (DMA), monomethylarsonic acid (MMA) and arsenate [As(V)] were obtained for all samples. A certificated reference material was also analyzed and the sum of As species was in agreement with the total As concentration. Limits of quantification (LOQ) for AsB, As(III), DMA, MMA, and As(V) were 6, 30, 6, 12 and 26 ng g-1, respectively. Higher concentration of AsB was found in all seafood, while As(III) and DMA were found only in oyster. Arsenate was found in squid and scallops, and MMA was below the LOQ in all samples.

AB - Caramel colours are used by the food industry in a wide range of foods and beverages. During their manufacturing, low molecular weight compounds such as 4 methylimidazole (4-MEI), the structural isomer of 4-MEI, 2-methylimidazole (2 MEI) and 2-acetyl-4-tetrahydroxy-butylimidazole (THI) are generated. The presence of these inevitable by-products of caramel manufacturing can be hazardous to human health. This publication describes an isotope dilution Ultra-High performance Liquid Chromatography tandem mass spectrometric method (UHPLC-MS/MS) that was developed and validated for the simultaneous quantification of these impurities in both beverages/liquids and foods. A limit of quantification of 5 MUg/kg was obtained for 4-MEI and THI. The expanded measurement uncertainty (U; k = 2) for these compounds was below 51% in beverages/liquids and below 56% in foods. As higher measurement uncertainties were obtained for 2-MEI, the developed analytical procedure can only be used in a semi-quantitative way for this compound. PMID- 29571487 TI - Deep eutectic solvent-based valorization of spent coffee grounds. AB - Spent coffee grounds (SCGs) are viewed as a valuable resource for useful bioactive compounds, such as chlorogenic acids and flavonoids, and we suggest an eco-friendly and efficient valorization method. A series of choline chloride based deep eutectic solvents (DESs) were tested as green extraction solvents for use with ultrasound-assisted extraction. Extraction efficiency was evaluated based on total phenolic content (TPC), total flavonoid content, total chlorogenic acids, and/or anti-oxidant activity. A binary DES named HC-6, which was composed of 1,6-hexanediol:choline chloride (molar ratio 7:1) was designed to produce the highest efficiency. Experimental conditions were screened and optimized for maximized efficiency using a two-level fractional factorial design and a central composite design, respectively. As a result, the proposed method presented significantly enhanced TPC and anti-oxidant activity. In addition, phenolic compounds could be easily recovered from extracts at high recovery yields (>90%) by adsorption chromatography.

AB - Milk powder is a food for malnourished African children and for healthy infants of women with HIV/AIDS. High demand and low purchasing power has resulted in a huge informal, black market in Sub-Saharan Africa. Forty-three milk powder batches were analyzed for 43 chemical elements using ICP-MS One sample (2.3%) was contaminated at a lead concentration of 240 ug/kg dry weight exceeding the European threshold (130 ug/kg dry weight). Macroelement contents revealed a trend decreasing in concentration through skimmed, full cream products to infant formulae. Concentration ranges by dry weight differed in respect of uncertainty intervals of +/-10%. Median Ca, K and P concentrations declined from 11.14 g/kg to 3.21 g/kg, 14.11 g/kg to 4.95 g/kg and 9.12 g/kg to 2.75 g/kg dry mass, respectively. Milk powder samples obtained from the Tanzanian black market were comparable in respect of nutritional and chemical content to international branded full cream products. PMID- 29571489 TI - Caramel colour and process contaminants in foods and beverages: Part II - Occurrence data and exposure assessment of 2-acetyl-4-(1,2,3,4 tetrahydroxybutyl)imidazole (THI) and 4-methylimidazole (4-MEI) in Belgium. AB - In Europe, 2-acetyl-4-(1,2,3,4-tetrahydroxybutyl)imidazole (THI) and 4 methylimidazole (4-MEI) are - to a certain level - allowed to be present in the food colours ammonia caramel (E 150c) and sulphite ammonia caramel (E 150d). Besides their presence in food colours, exposure to these contaminants may also include other dietary sources. This study describes the occurrence of THI and 4 MEI in a wide variety of food products (n = 522) purchased from the Belgian market and their dietary intake in Belgian consumers from 15 years old onwards. THI was found to be present in 22.4% of the investigated foods at a level up to 551 ug/kg. For 4-MEI (57.7% quantifiable), concentrations up to 2,835 ug/kg were observed. The average dietary intake amounted to 0.02-0.36 ug kg-1 bw-1 day for THI and 0.4-3.7 ug kg-1 bw-1 day for 4-MEI. Coffee, cola and beer were contributing most to the dietary THI and 4-MEI intake in Belgium. PMID- 29571490 TI - Enzyme immunoassay (ELISA/immunosensor) for a sensitive detection of pork adulteration in meat. AB - ELISA/immunosensor were developed for a sensitive detection of pork adulteration in meat. Two formats of ELISA were performed. First, an extracted IgG was directly immobilized in the microplate. This assay allowed an identification of 0.01% as level of pork adulteration in 14 h15 min. In order to decrease the time of the assay, a competitive ELISA was developed by immobilizing IgG standard, which compete with the extracted IgG. This assay allowed a detection of 0.1% of pork adulteration in 45 min. Furthermore, two formats of electrochemical immunosensors were elaborated using the electro-entrapment of IgG in polymer modified graphite paste electrode. First, a direct immunosensor was capable of identifying 0.1 and 1% in raw and cooked meat respectively in 2 h. The second format was based on a competitive immunosensor, which was able to detect 0.01% of pork adulteration within 20 min. Both competitive immunoassays revealed high sensitivity, good specify and reduced analysis time. PMID- 29571491 TI - Ethanol-induced composite hydrogel based on propylene glycol alginate and zein: Formation, characterization and application. AB - A novel ethanol-induced composite hydrogel was prepared by two edible biopolymers: propylene glycol alginate (PGA) and zein. The effect of pH and different mass ratios of PGA and zein on the properties of the composite hydrogel was investigated. PGA and zein could form a gel induced by ethanol at pH >= 3.5, the stability, springiness, hardness and water holding capacity were decreased from pH 3.5 to 5.0. The hydrogen-bonding association was enhanced at pH 3.5 and porous structure was observed. The strength and springiness of the composite hydrogel decreased with increasing concentration of zein until the PGA/zein mass ratio was 5:1. At PGA/zein mass ratio of 5:1, the composite hydrogel exhibited a more elastic and tougher structure than other mass ratios at pH 3.5. Meanwhile, compared with the PGA hydrogel, the PGA-zein composite hydrogel showed great ability to sustain the release of curcumin in simulated gastrointestinal tract conditions. PMID- 29571492 TI - First evaluation of drug-in-cyclodextrin-in-liposomes as an encapsulating system for nerolidol. AB - Nerolidol, a naturally occurring sesquiterpene with antimicrobial activities, is a promising candidate as a natural alternative for synthetic preservatives in food. However, its application is limited by low aqueous solubility and stability. In this study, conventional liposomes and drug-in-cyclodextrin-in liposomes (DCLs) were evaluated for the first time as encapsulating materials for nerolidol. The size, encapsulation efficiency (EE%), loading rate (LR%), photo- and storage stabilities of both systems were characterized. Moreover, the in vitro release of nerolidol from liposomes and DCLs was investigated over time. Nerolidol was efficiently entrapped in both carriers with high EE% and LR% values. In addition, DCLs prolonged the release of nerolidol over one week and enhanced the photostability more effectively than conventional liposomes. Finally, all formulations were stable after 12 months of storage at 4 degrees C (>60% incorporated nerolidol). Therefore, DCLs are promising carriers for new applications of sesquiterpenes in the pharmaceutical and food industries. PMID- 29571493 TI - A low trans margarine fat analog to beef tallow for healthier formulations: Optimization of enzymatic interesterification using soybean oil and fully hydrogenated palm oil. AB - The health hazard of tallow and partial hydrogenated oils is well known in margarine productions. For this, food manufactures are urged to develop novel alternatives for healthier margarine formulations. The highest interesterification degree acquired with lipase Lipozyme 435 standing out from other catalysts (solid acid, sodium hydroxide and methoxide) was applied to produce low trans margarine fat analogs to beef tallow (BT) with the blend of soybean oil (SO) and fully hydrogenated palm oil (FHPO) in a mass ratio of 4:3. Reaction parameters like enzyme dosage (4.2 wt%), temperature (95 degrees C) and time (245 min) were optimized using the Box-Behnken design. Regarding fatty acid profiles, triacylglycerol species, solid fat content, polymorphism, melting and crystallization behaviors, the resulting interesterified oil was characterized in comparison with BT, FHPO and the SO-FHPO blend so as to prove its potential in formulating low trans fat margarines because of desirable physicochemical properties and polymorphs. PMID- 29571494 TI - A new formaldehyde sensor from silver nanoclusters modified Tollens' reagent. AB - A selective colorimetric assay for detecting formaldehyde (FA) was proposed based on silver nanoclusters (AgNCs) templated by polymethacrylic acid (PMAA). The chemodosimeter was easily fabricated by the formation of Tollens' reagent in the presence of AgNCs (AgNCs@Tollens). The detection principle was based on the change in the color caused by the change in the particle size from nanoclusters (no LSPR) to nanoparticles (with LSPR) upon the reduction of Tollens' reagent by FA. In the presence of FA, the intensity of a new absorbance band with a maximum at a wavelength of 430 nm corresponding to the LSPR of the AgNPs linearly increased as a function of the FA concentration, exhibiting a color change that could be observed by the naked eye. This method provided a working range of 30-50 uM with lower detection limit (LOD) of 27.99 uM. The proposed method exhibited excellent selectivity towards FA over other aldehyde-containing compounds. PMID- 29571495 TI - Impact of roasting on the flavan-3-ol composition, sensory-related chemistry, and in vitro pancreatic lipase inhibitory activity of cocoa beans. AB - Roasting is an important cocoa processing step, but has been reported to reduce the polyphenol content in the beans. We investigated the impact of whole-bean roasting on the polyphenol content, aroma-related chemistry, and in vitro pancreatic lipase (PL) inhibitory activity of cocoa under a range of roasting conditions. Total phenolics, (-)-epicatechin, and proanthocyanidin (PAC) dimer - pentamer content was reduced by roasting. By contrast, roasting at 150 degrees C or greater increased the levels of catechin and PAC hexamers and heptamers. These compounds have greater PL inhibitory potency. Consistent with these changes in PAC composition and this previous data, we found that roasting at 170 degrees C time-dependently increased PL inhibitory activity. Cocoa aroma-related compounds increased with roasting above 100 degrees C, whereas deleterious sensory-related compounds formed at more severe temperatures. Our results indicate that cocoa roasting can be optimized to increase the content of larger PACs and anti-PL activity, while maintaining a favorable aroma profile. PMID- 29571496 TI - Fluoroimmunoassays for the detection of zearalenone in maize using CdTe/CdS/ZnS quantum dots. AB - CdTe/CdS/ZnS quantum dots (QDs) were synthesized in aqueous phase and conjugated with a new anti-zearalenone (ZEN) monoclonal antibody. Using this novel fluorescent probe, a fluoroimmunoassay (FLISA) and a rapid immunochromatographic strip (ICTS) were developed for the detection of ZEN in maize. Our proposed FLISA allowed for ZEN determination in the range of 0.038-0.977 ng/mL with an IC50 of 0.162 ng/mL and a limit of detection (LOD) of 0.012 ng/mL occurring in maize. The rapid ICTS had a visual LOD of 1.0 ng/mL in buffer solution and 1.5 ng/mL in maize extract. These two QDs-based immunoassays were all successfully verified by commercial ELISA kits. The results confirmed that: firstly, the FLISA can be used as a robust method for the sensitive detection of ZEN; and secondly, the ICTS is ideally suited for rapidly screening large numbers of samples. PMID- 29571497 TI - Influence of indigenous minor components on fat crystal network of fully hydrogenated palm kernel oil and fully hydrogenated coconut oil. AB - Purification of triglycerides from fully hydrogenated palm kernel oil (FHPKO) and fully hydrogenated coconut oil (FHCNO) was performed by a chromatographic method. Lipid composition, thermal properties, polymorphism, isothermal crystallization behaviour, nanostructure and microstructure of FHPKO, FHPKO-triacylglycerol (TAG), FHCNO and FHCNO-TAG were evaluated. Removal of minor components had no effect on triglycerides composition. However, the presence of the minor components did increase the slip melting point and promote onset of crystallization. Furthermore, the thickness of the nanoscale crystals increased, and polymorphic transformation from beta' to beta occurred in FHPKO after the removal of minor components, and from alpha to beta' in FHCNO. Sharp changes in the values of the Avrami constant K and exponent n suggested that the presence of minor components changed the crystal growth mechanism. The PLM results indicated that a coarser crystal structure with lower fractal dimension appeared after the removal of minor components from both FHPKO and FHCNO. PMID- 29571498 TI - Chemical, sensory, and functional properties of whey-based popsicles manufactured with watermelon juice concentrated at different temperatures. AB - The effects of the concentration of watermelon juice at different temperatures (45, 55, or 65 degrees C) on the physicochemical and sensory characteristics, antioxidant capacity, and volatile organic compounds (VOCs) of whey-based popsicles were investigated. Total phenolic content, lycopene, citrulline, VOCs, melting rate, instrumental colour, antioxidant capacity, and the sensory characteristics (hedonic test and free listing) were determined. The temperature led to a significant decrease in bioactive compounds (total phenolics, lycopene, and citrulline). The popsicle manufactured with reconstituted watermelon juice concentrated to 60 degrees Brix at 65 degrees C presented higher antioxidant capacity and was characterized by the presence of alcohols, aldehydes and ketones and presented a similar acceptance to the untreated popsicle (except for flavour). It is possible to combine whey and concentrated watermelon juice for the manufacture of bioactive-rich popsicles, using the concentration temperature of 65 degrees C as a suitable processing condition for potential industrial applications. PMID- 29571499 TI - Formulation and characterization of astaxanthin-enriched nanoemulsions stabilized using ginseng saponins as natural emulsifiers. AB - In this study ginseng saponins (GS) were used as natural emulsifiers to formulate and stabilize O/W nanoemulsions loaded with astaxanthin (AST). GS were found to be highly effective at reducing the interfacial tension at the soybean oil-water interfaces, and were capable of producing nano-scaled droplets (d4,3 ~ 125 nm) using a high-pressure homogenizer. The droplet size of the nanoemulsions decreased with increasing emulsifier concentration and homogenization pressure. The nanoemulsions were stable without droplet coalescence against thermal treatment (30-90 degrees C, 30 min), and over a narrow range of pH values (7-9). GS-coated droplets were unstable in acidic conditions (pH 3-6) and in the presence of salt (>25 mM NaCl). The formulated nanoemulsions showed slight change in d4,3 during 15 days of storage at 5, 25 and 40 degrees C. However, the chemical stability strongly depended on the storage temperature, with the lowest level of AST retained in nanoemulsions stored at higher temperature. PMID- 29571500 TI - Development of pure certified reference material of stevioside. AB - Pure stevioside was extracted from leaves of Stevia rebaudiana (Bertoni) to be used as a reference material in the instrument calibration or method validation process. The mass fraction was determined by comparison between the mass balance method and quantitative nuclear magnetic resonance (qNMR) spectroscopy. The impurities in the sample were analyzed by Karl Fischer titration for moisture content and thermogravimetric analysis for inorganic residue. Homogeneity, together with short term and long term stability, were also studied and the uncertainty was reported. The certified value of this mass fraction is 0.986 +/- 0.0019 (k = 2) with 1 year stability. PMID- 29571501 TI - A study on interactions between the insoluble fractions of different coffee infusions and major cocoa free antioxidants and different coffee infusions and dark chocolate. AB - This study aimed to investigate the interactions between insoluble fractions of different coffee infusions and major cocoa free antioxidants, catechin and epicatechin, as well as the interactions between different coffee infusions and dark chocolate. Espresso, filtered coffee, French press and Turkish coffee were used for this purpose. Antioxidant capacity (AC) measurements were performed by monitoring the percentage inhibition of 2,2-Diphenyl-1-picrylhydrazil (DPPH) radical. Multivariate approach was adopted for experimental design and data analysis steps. In dry basis, the AC values of infusions (mmol Trolox/kg) were ranged between 953 +/- 2.6 and 1184 +/- 11.3, while the AC values for their insoluble fractions were ranged between 45 +/- 0.0 and 105-1.3. Interactions between the insoluble fractions of coffee infusions and catechins were synergistic for espresso and additive/antagonistic for the other infusions. Interactions between coffee infusions and chocolate were synergistic for French press and Turkish coffee and additive/antagonistic for the other infusions. PMID- 29571502 TI - Application of magnetic molecularly imprinted polymers for extraction of imidacloprid from eggplant and honey. AB - A magnetic molecularly imprinted polymer (MMIP) adsorbent for imidacloprid was prepared using non-covalent approach with functionalized nano Fe3O4 particles (magnetic cores), imidacloprid (template), acrylic acid (functional monomer), ethylene glycol dimethacrylate (cross linker) and azobisisobutyronitrile (initiator) and used for selective separation of imidacloprid from honey and vegetable samples. The polymers were characterized using FT-IR spectroscopy, SEM and TEM images. For analysis of imidacloprid LC-MS/MS equipment was used. Adsorption kinetics was best explained by pseudo-second-order kinetic model. Adsorption data fitted well into linearized Freundlich equation (R2 > 0.98). Scatchard plot analysis indicates the presence of two classes of binding sites in the MMIPs with the Cmax of 1889.6 ug g-1 and 65448.9 ug g-1, respectively. MMIPs demonstrated much higher affinity for imidacloprid over structurally similar analogues acetamiprid (alpha = 23.59) and thiamethoxam (alpha = 17.15). About 87.1 +/- 5.0% and 90.6 +/- 5.6% of the added imidacloprid was recovered from MMIPs in case of fortified eggplant and honey samples, respectively. PMID- 29571503 TI - Functional attributes of a new molecule-2-hydroxymethyl-benzoic acid 2'-hydroxy tetradecyl ester isolated from Talaromyces purpureogenus CFRM02. AB - An account of antioxidant and antimicrobial characteristics displayed by ethyl acetate extract of Talaromyces purpureogenus CFRM-02 cultivated by submerged fermentation on bengal gram husk (BegH) led to the isolation of a new molecule, which was purified via silica gel column chromatography. The TLC and HPLC data revealed the purity of the isolated compound. By employing an array of spectroscopic techniques, structural elucidation was accomplished, and the molecule was identified as 2-hydroxymethyl-benzoic acid 2'-hydroxy-tetradecyl ester and was also designated with a familiar name pentalsamonin. The pentalsamonin molecule scavenged DPPH (24%), H2O2 (64%), superoxide anion (58%) with a reducing power (0.989 AU) at the given concentration. The MIC and MBC of pentalsamonin against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae are in the range 62.5-125 and 125-250 ug/ml, respectively. The antioxidant and antibacterial functional attributes of pentalsamonin suggest useful applications in food and nutraceuticals. PMID- 29571504 TI - Reverse micelles as nanocarriers of nisin against foodborne pathogens. AB - Reverse micelles (RMs) as nanocarriers of nisin were optimized for the highest water and bacteriocin content. RMs formulated with either refined olive oil or sunflower oil, distilled monoglycerides, ethanol, and water were effectively designed. Structural characterization of the RMs was assessed using Electron Paramagnetic Resonance Spectroscopy and Small Angle X-ray Scattering in the presence and absence of nisin. No conformational changes occurred in the presence of nisin for the nanocarriers. To assess efficacy of the loaded systems, their antimicrobial activity against Staphylococcus aureus and Listeria monocytogenes was tested in lettuce leaves and minced meat, respectively. Antimicrobial activity was evident in both cases. Interestingly, a synergistic antimicrobial effect was observed in lettuce leaves and to a lesser extent in minced meat between nisin and some of the nanocarriers' constituents (probably ethanol). Our findings suggest complex interactions that take place when RMs are applied in different food matrices. PMID- 29571505 TI - Screening thresholds: one size does not fit all.

AB - AIMS: Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne's disease. To survive within host macrophages, the pathogen secretes a battery of proteins to interfere with the immunological response of the host. One of these proteins is tyrosine phosphate A (PtpA), which has been identified as a secreted protein critical for survival of its close relative M. tuberculosis within infected macrophages. METHODS AND RESULTS: In this study, the immune response to recombinant PtpA used as an antigen was investigated in a cohort of ~1000 cows infected with MAP compared to negative control animals using ELISA. The sera from MAP-infected cows had significantly higher levels of antibodies against PtpA when compared to uninfected cows. CONCLUSIONS: The data presented here indicate that the antibodies produced against PtpA are sensitive enough to detect infected animals before the appearance of the disease symptoms. SIGNIFICANCE AND IMPACT OF STUDY: The use of PtpA as an antigen can be developed as an early diagnostic test. Moreover, PtpA is a candidate antigen for detection of humoral immune responses in cows infected with MAP. PMID- 29571514 TI - Development and characterization of monoclonal antibodies against canine PD-1 and PD-L1. AB - Recent research has focused on immunotherapy, particularly with regard to cancer treatment. Programmed death-1 and programmed death ligand 1 (PD-1/PD-L1) pathway blockade is a central topic of the promising immunotherapy field. In veterinary medicine, observations of the PD-1/PD-L1 pathway, including the relationship between immune cells and diseases, have increased. In this study, monoclonal antibodies specific to canine PD-1 and PD-L1 were developed, and the antibodies against PD-1 and PD-L1 bind to PD-1 and PD-L1 overexpressing cells, respectively. Additionally, each antibody interfered with the interaction between PD-1 and PD L1. The expression of PD-1 and PD-L1 was detected on activated T cells from canine peripheral blood mononuclear cells (PBMC), and, remarkably, was the first recorded instance of PD-L1 expression on canine immature dendritic cells. Production of IFN-gamma by activated T cells increased significantly when incubated with anti-PD-1 antibody alone and with both anti-PD-1 and anti-PD-L1 antibodies, revealing the functional effects of the antibodies. The antibodies will be useful for research on immune systems and may be the first passive immunotherapy approach in canine cancer patients. PMID- 29571513 TI - Seroprevalence for Brucella spp. in Baltic ringed seals (Phoca hispida) and East Greenland harp (Pagophilus groenlandicus) and hooded (Cystophora cristata) seals. AB - Zoonotic infections transmitted from marine mammals to humans in the Baltic and European Arctic are of unknown significance, despite given considerable potential for transmission due to local hunt. Here we present results of an initial screening for Brucella spp. in Arctic and Baltic seal species. Baltic ringed seals (Pusa hispida, n = 12) sampled in October 2015 and Greenland Sea harp seals (Pagophilus groenlandicus, n = 6) and hooded seals (Cystophora cristata, n = 3) sampled in March 2015 were serologically analysed for antibodies against Brucella spp. The serological analyses were performed using the Rose Bengal Test (RBT) followed by a confirmatory testing of RBT-positive samples by a competitive enzyme linked immunosorbent assay (C-ELISA). Two of the Baltic ringed seals (a juvenile male and a juvenile female) were seropositive thus indicating previous exposure to a Brucella spp. The findings indicate that ringed seals in the Baltic ecosystem may be exposed to and possibly infected by Brucella spp. No seropositive individuals were detected among the Greenland harp and hooded seals. Although our initial screening shows a zoonotic hazard to Baltic locals, a more in-depth epidemiological investigation is needed in order to determine the human risk associated with this. PMID- 29571515 TI - CK-2 of rainbow trout (Oncorhynchus mykiss) has two differentially regulated alleles that encode a functional chemokine. AB - Rainbow trout chemokine 2 (CK-2) is currently the only known CC chemokine to have a mucin stalk. Further analysis of the mucin stalk region revealed a second, related CC chemokine sequence, denoted here as CK-2.1. This second sequence was determined to be an allele of CK-2 following genomic PCR analysis on several outbred individuals. Furthermore, in both in vivo and in vitro trials, CK-2 and CK-2.1 were both present, but appeared to have differential tissue expression in both control and PHA stimulated samples. Upon the development of a polyclonal antibody to rCK-2, CK-2 was only observed in the brain, liver and head kidney of PHA stimulated rainbow trout tissues. In comparison, when using the rainbow trout monocyte/macrophage-like cell line, RTS-11, CK-2 protein was observed in both control and PHA stimulated conditions. When studying the function of CK-2, a chemotaxis assay revealed that both peripheral blood leukocytes and RTS-11 cells migrated towards rCK-2 significantly at all concentrations studied when compared to truncated beta2m. Interestingly, this migration was lowest at both the highest concentration and the lowest concentrations of CK-2. Thus, teleostean chemokine receptors may become desensitized when overstimulated as has been observed in mammalian models. The observed chemotactic function was indeed due to rCK-2 as cell migration was inhibited through pre-treatment of both the cells and the polyclonal antibody with rCK-2. As has been observed thus far with all other chemokines, CK-2 does appear to function through binding to a G-coupled protein receptor as chemotaxis could be inhibited through pre-treatment with pertussis toxin. Overall, the results of this study indicate that CK-2 is a functional chemokine that is encoded by two differentially expressed alleles in rainbow trout, CK-2 and CK-2.1. PMID- 29571516 TI - Low pathogenic avian influenza virus infection increases the staining intensity of KUL01+ cells including macrophages yet decrease of the staining intensity of KUL01+ cells using clodronate liposomes did not affect the viral genome loads in chickens. AB - The effect of depletion of macrophages using clodronate liposomes as well as macrophage response following viral infections have been studied in various mouse virus infection models, but they have not been extensively studied in chickens relevant to virus infections. When we infected day 6 chickens with H4N6 low pathogenic avian influenza virus (LPAIV), we observed that H4N6 LPAIV infection increased the staining intensity of KUL01+ cells in trachea, lungs and duodenum of chickens at 3 days post-infection. Then, we used clodronate liposomes intra abdominally in 5 day-old chickens and found significant reduction of staining intensity of KUL01+ cells in trachea and duodenum but not in lungs at 4 days post treatment. When we infected the clodronate liposome and PBS liposome treated chickens with H4N6 LPAIV intra-nasally at day 6, we found no effect on H4N6 LPAIV genome loads in trachea, lungs and duodenum of chickens. This study indicates that although KUL01+ cell intensity are increased in respiratory and gastrointestinal tissues in chickens following H4N6 LPAIV infection, the decrease of KUL01+ cell intensity using clodronate liposomes did not change the H4N6 LPAIV genome loads in any of the examined tissues suggesting that KUL01+ cells may not be critical during H4N6 LPAIV infection in chicken. PMID- 29571517 TI - Evaluation of immune responses in mice and sheep inoculated with a live attenuated Brucella melitensis REV1 vaccine produced in bioreactor. AB - The Brucella melitensis REV1 vaccine is the most widely employed vaccine for prophylaxis against brucellosis in sheep and goats. The objective of vaccination is disease control in herds or preventing infection in farms. In this study, we produced REV1 vaccine with a protocol, based on the use of liquid medium in a bioreactor, that resulted efficient, safe, relatively fast, and cost-effective. The live attenuated vaccine produced was tested in mice and sheep to investigate its immunogenicity and efficacy. Seventy-two female BALB/c mice were obtained and subdivided in 2 groups, one was stimulated with 1 * 106 colony-forming units (CFUs) of B. melitensis while the other with physiological solution alone and acting as control group. Furthermore, 25 sheep were subdivided into 5 groups: four were inoculated with a B. melitensis dose, ranging from 0.6 * 109 and 3.2 * 109 CFUs and the other was the control group. In addition, a serological diagnosis was performed for sheep by rapid serum agglutination and the complement fixation test. Immunocompetent cells from both experiment were collected at different times post vaccination and immunostained to evaluate innate and adaptive-immune responses. In mice flow cytometry was used to detect macrophages, T lymphocytes, dendritic cells, memory cells, naive cells, natural killer cells, major histocompatibility complex type II, B lymphocytes, regulatory T lymphocytes, T helper lymphocytes, cytotoxic T lymphocytes and recently activated CD4+ and CD8+ lymphocytes. In sheep, macrophages, T helper cells, cytotoxic T lymphocytes, regulatory T lymphocytes, dendritic cells, memory cells and naive lymphocytes, by the same method, were analyzed. The results showed, both in mice and sheep, that the live, attenuated REV1 vaccine stimulated all immunocompetent cells tested, with a balanced innate and adaptive response. In the sheep experiment, the administered vaccine dose was very important because, at the lower doses, immunological tolerance tended to disappear, while, at the highest dose, the immunological tolerance remained active for a long period. In our experimental conditions, the optimal vaccine dose for sheep was 3.2 * 109 CFUs, although a good immune response was found using a dose of 1.6 * 109 CFUs. The vaccine produced in this study could be extensively employed in developing countries to control the brucellosis in sheep and goats.

AB - Canine histiocytic sarcoma (HS) represents a malignant neoplastic disorder often with a rapid and progressive clinical course. A better understanding of the interaction between tumor cells and the local microenvironment may provide new insights into mechanisms of tumor growth and metastasis. The influence of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) on tumor angiogenesis, invasion and metastasis has been detailed in previous studies. In addition, inflammatory cells infiltrating neoplasms especially tumor associated macrophages (TAM) may contribute significantly to tumor progression. Due to the high variability of spontaneously occurring canine HS, standardized models are highly required to investigate tumor progression and interaction with its microenvironment. Therefore, the present study comparatively characterized the intratumoral macrophage infiltration as well as the expression of MMP-2, MMP-9, MMP-14 and TIMP-1 in spontaneous canine HS and its murine model. In spontaneous canine HS, scattered MAC 387-positive macrophages were randomly found in tumor center and periphery, whereas tumor cells were negative for this marker. Interestingly, quantitative analysis revealed that MMPs and TIMP-1 were mainly expressed at the invasive front while tumor centers exhibited significantly reduced immunoreactivity. Similar findings were obtained in xenotransplanted HS. Interestingly, murine tumor associated macrophages (TAM), characterized by Mac3 expression (CD107b/LAMP2), which was not present in xenotransplanted histiocytic sarcoma cells, strongly express MMPs and TIMP-1. In addition, MMPs are known to regulate angiogenesis and a positive correlation between MMP-14 expression and microvessel density was demonstrated in xenotransplanted histiocytic sarcomas. Summarized similar findings with respect to MMP and TIMP distribution and the role of macrophages in spontaneously-occurring and xenotransplanted HS indicate the high suitability of this murine model to further investigate HS under standardized conditions. Moreover results indicate that MMP expression contributes to tumor progression and invasion and TAMs seem to be major players in the interaction between neoplastic cells, the microenvironment and vessel formation indicating that therapeutic approaches modulating TAM associated molecules might represent promising future treatment options.

AB - The scavenger receptor CD163 is widely used as a cell signature for alternatively active "M2" macrophages in mammals. In this study, we generated two monoclonal antibodies, ABM-1A9 and ABM-2D6, against the extracellular region of bovine CD163. Conventional Western blotting using the antibodies yielded immunoreactive bands of bovine CD163 at 130 and 150 kDa in non-reduced and reduced spleen lysates, respectively. The minimum limit of detectable concentration of both antibodies was relatively lower (5.0 ng/mL) than that of the anti-human CD163 monoclonal antibody AM-3 K (>1.0 MUg/mL), which has been used previously for the detection of bovine CD163. An immunohistochemical study using formalin-fixed paraffin-embedded sections revealed that ABM-1A9 and ABM-2D6 clearly stained some Iba1+ macrophages in the lymph nodes of cattle with mastitis. Moreover, the CD163 stained macrophages were frequently observed engulfing leukocytes. ELISA using ABM-2D6 distinguished levels of circulating soluble CD163 in healthy cattle (less than 16.9 pmol/mL) and cattle with mastitis (more than 33.7 pmol/mL). These new monoclonal antibodies can be used in the diagnosis and evaluation of inflammatory disease prognosis in cattle with immunohistological analyses and blood test applications. PMID- 29571520 TI - Changes in serum anti-Leishmania antibody concentrations measured by time resolved immunofluorometric assays in dogs with leishmaniosis after treatment. AB - The aim of this study was to evaluate the changes in anti-Leishmania IgG2 and IgA antibodies measured by two time-resolved immunofluorometric assays (TR-IFMAs) recently validated and by means of a commercially available ELISA test in dogs with leishmaniosis after treatment. Serum samples from 16 dogs with clinical leishmaniosis were obtained on days 0, 30 and 180 of treatment. In addition, these serological changes were compared with the clinical signs and selected analytes (total proteins, albumin, globulins and urinary protein:creatinine ratio). Concentrations of IgG2 and IgA by TR-IFMA were significantly lower on days 30 (p < 0.05) and 180 of treatment (p < 0.0001) compared to day 0 in dogs that showed a positive response to treatment. Magnitudes of decrease of IgG2 (1.66 and 20.4-fold) and IgA (1.3 and 11.43-fold) concentrations on days 30 and 180 were greater than those of the commercially available ELISA test (1.29 and 2.06-fold), and that of other analytes (total proteins: 1.11 and 1.25-fold; globulins: 1.22 and 1.74-fold; and albumin: 0.93 and 0.8-fold). This study shows that serum IgG2 and IgA anti-Leishmania antibodies measured by TR-IFMAs were useful for treatment monitoring in dogs with leishmaniosis, showing a significant reduction in antibody concentrations earlier than the commercial ELISA assay. Results suggest that the method used for antibody measurements greatly influences the results and, consequently, the usefulness for measuring anti-Leishmania antibodies to monitor the treatment of canine leishmaniosis. PMID- 29571521 TI - Outpatient Dermatological Diagnoses in Spain: Results From the National DIADERM Random Sampling Project. AB - INTRODUCTION: Dermatologists perform most of their work in outpatient or private clinics. Data on the diagnoses made by dermatologists in these settings are lacking, however, as outpatient activity, unlike hospital activity, is difficult to code. The aim of this study was to analyze the diagnoses made by members of the Spanish Academy of Dermatology and Venereology (AEDV) at dermatology clinics in Spain. METHODOLOGY: We selected a random sample of AEDV dermatologists drawn from the AEDV list and stratified by geographic area. The selected dermatologists received instructions on how to collect the data required. Each participant recorded the diagnosis reached and other data for patients seen during 2 specified periods: 3 days in January and 3 days in May. The diagnoses were subsequently coded by a dermatologist expert in applying the International Classification of Diseases (10th revision). In view of the complex nature of the sample, data were analyzed with standard error and finite population corrections. RESULTS: The sample consisted of 124 dermatologists. Of these, 65% participated in the first phase of the study and 59% in the second. An estimated 621 562 patients (95% CI, 368 130-874 995) visit the dermatologist every month in Spain. This is the equivalent of 28 (25-31) patients per day per clinic. The most common diagnosis recorded was actinic keratosis, followed by basal cell carcinoma and melanocytic nevus. The vast majority of visits took place at the clinic, but 1% of patients (0.3%-3%) were assessed using teledermatology. CONCLUSIONS: This is the first study in Spain to analyze diagnoses made by AEDV members at outpatient dermatology clinics. Our findings show a high volume of activity and will be useful for guiding health care planning, resource use, and future studies.

AB - INTRODUCTION: Congenital Aural Atresia (CAA) or microtia is a malformation that results in esthetic and functional problems. There is little information on prevalence, considering that Latin American is the most affected region in the world. OBJECTIVE: To determine the prevalence of microtia, considering the different ethnical structure of the population. METHODS: A retrospective analysis was performed of the clinical reports of newborn infants (public hospitals) in three different regions. RESULTS: The incidence of CAA in Argentina was 1 case per 7500 new births (i.e. 1.3/10,000). Marked differences were found per geographical area. The means were calculated per year by bilateral parametric estimation, according to the ethnical origins of the population. In the Caucasoid area: 02.47/10,000 (+/-1.2), in the Mestizo area: 03.99/10,000 (+/-0.0) and finally in the Amerindian area: 20.93/10,000 (+/-0.1). CONCLUSION: This study shows different incidences according to the demographic features of the population from 1.90/10,000 to 20.9/10,000. This data indicates that CAA is associated with a genetic problem (ethnic differences).

AB - The current study investigated the relations among traditional and cyber victimization, depressive symptoms, suicidal ideation, and gender in a school based sample of 403 9th grade (13 to 16-year-old) adolescents. Path analyses indicated that both traditional victimization and cyber victimization were associated with suicidal ideation indirectly through depressive symptoms. Although there was little evidence of gender differences in the associations among peer victimization and depressive symptoms and suicidal ideation, the relation between depressive symptoms and suicidal ideation was found to be significantly stronger for girls than boys. The current investigation confirms the complexity of the association between peer victimization and suicidal ideation and that depressive symptoms, as well as gender, may play a role in this complex relation. Future research should continue to explore the associations among victimization, depressive symptoms, and suicidal ideation within a social ecological framework.

AB - Three-dimensional virtual environments enable very realistic ludic, social, cultural, and educational activities to be carried out online. Second Life(r) is one of the most well-known virtual environments, in which numerous training activities have been developed for healthcare professionals, although none about radiology. The aim of this article is to present the technical resources and educational activities that Second Life(r) offers for training in radiology based on our experience since 2011 with diverse training activities for undergraduate and postgraduate students. Second Life(r) is useful for carrying out radiology training activities online through remote access in an attractive scenario, especially for current generations of students and residents. More than 800 participants have reported in individual satisfaction surveys that their experiences with this approach have been interesting and useful for their training in radiology. PMID- 29571524 TI - Habits Are Negatively Regulated by Histone Deacetylase 3 in the Dorsal Striatum. AB - BACKGROUND: Optimal behavior and decision making result from a balance of control between two strategies, one cognitive/goal-directed and one habitual. These systems are known to rely on the anatomically distinct dorsomedial and dorsolateral striatum, respectively. However, the transcriptional regulatory mechanisms required to learn and transition between these strategies are unknown. Here we examined the role of one chromatin-based transcriptional regulator, histone modification via histone deacetylases (HDACs), in this process. METHODS: We combined procedures that diagnose behavioral strategy in rats with pharmacological and viral-mediated HDAC manipulations, chromatin immunoprecipitation, and messenger RNA quantification. RESULTS: The results indicate that dorsal striatal HDAC3 activity constrains habit formation. Systemic HDAC inhibition following instrumental (lever press -> reward) conditioning increased histone acetylation throughout the dorsal striatum and accelerated habitual control of behavior. HDAC3 was removed from the promoters of key learning-related genes in the dorsal striatum as habits formed with overtraining and with posttraining HDAC inhibition. Decreasing HDAC3 function, either by selective pharmacological inhibition or by expression of dominant-negative mutated HDAC3, in either the dorsolateral striatum or the dorsomedial striatum accelerated habit formation, while HDAC3 overexpression in either region prevented habit. CONCLUSIONS: These results challenge the strict dissociation between dorsomedial striatum and dorsolateral striatum function in goal-directed versus habitual behavioral control and identify dorsostriatal HDAC3 as a critical molecular directive of the transition to habit. Because this transition is disrupted in many neurodegenerative and psychiatric diseases, these data suggest a potential molecular mechanism for the negative behavioral symptoms of these conditions and a target for therapeutic intervention. PMID- 29571527 TI - Cognitive ability influences on written expression: Evidence for developmental and sex-based differences in school-age children. AB - Some studies have demonstrated that the Cattell-Horn-Carroll (CHC) cognitive abilities influence writing; however, little research has investigated whether CHC cognitive abilities influence writing the same way for males and females across grades. We used multiple group structural equation models to investigate whether CHC cognitive ability influences on written expression differed between grades or sex using the Kaufman Assessment Battery for Children, Second Edition and the Kaufman Tests of Educational Achievement, Second Edition co-normed standardization sample data (N=2117). After testing for consistent measurement of cognitive abilities across grades and sex, we tested whether the cognitive ability influences on written expression were moderated by grade level or sex. An important developmental shift was observed equally across sex groups: Learning Efficiency (Gl) influences decreased whereas Crystallized Ability (Gc) influences increased after fourth grade. Further, Short-Term Memory (Gsm) and Retrieval Fluency (Gr) influences on written expression depended on sex at grades 1-4, with larger Gr influences for females and larger Gsm influences for males. We internally replicated our main findings using two different cognitive explanatory models, adding further support for the developmental and sex-based differential cognitive ability influences on writing. Explanatory cognitive models of writing need to incorporate development, and possibly, sex to provide an expanded understanding of writing development and guard against potential generalizability issues characteristic of special population (i.e., male-female) studies. PMID- 29571528 TI - Investigating teacher and student effects of the Incredible Years Classroom Management Program in early elementary school. AB - The present paper reports on the results of a cluster randomized trial of the Incredible Years(r) Teacher Classroom Management Program (IY-TCM) and its effects on early elementary teachers' management strategies, classroom climate, and students' emotion regulation, attention, and academic competence. IY-TCM was implemented in 11 rural and semi-rural schools with K-2 teachers and a diverse student sample. Outcomes were compared for 45 teachers who participated in five full day training workshops and brief classroom consultation and 46 control teachers; these 91 teachers had a total of 1192 students. A high level of teacher satisfaction was found and specific aspects of the training considered most valuable for early elementary teachers were identified. Hierarchical linear modeling indicated a statistically significant intervention effect on Positive Climate in the classroom (d=0.45) that did not sustain into the next school year. No main effects on student outcomes were observed, although a priori moderator analyses indicated that students with elevated social-behavioral difficulties benefitted with regard to prosocial behavior (d=0.54) and inattention (d=-0.34). Results highlight potential benefits and limitations of a universal teacher training program for elementary students, and suggest strategies for future delivery of the IY-TCM program and areas for future research. PMID- 29571529 TI - Teaching in ethnically diverse classrooms: Examining individual differences in teacher self-efficacy. AB - Using data of 40 native Dutch teachers and their native majority (n=112) and ethnic minority students (n=180), this study examined to what extent teachers experience differences in self-efficacy in teaching individual majority and minority students. We hypothesized that teachers would feel less self-efficacious in relation to ethnic minority students and that the difference in self-efficacy would be more pronounced when ethnic group differences are more salient (i.e., in the context of behavioral problems, ethnically less diverse classrooms, and for teachers with high ethnic identification). Our results show that teachers feel somewhat less self-efficacious with ethnic minority versus majority students. And, the difference in self-efficacy with minority versus majority students was more pronounced in relation to internalizing problem behaviors and somewhat more distinct in classrooms with relatively few ethnic minority students. The findings indicate the importance of a student specific assessment of teacher self-efficacy in diverse school contexts. PMID- 29571530 TI - Trajectories of teacher-student warmth and conflict at the transition to middle school: Effects on academic engagement and achievement. AB - Using piece-wise longitudinal trajectory analysis, this study investigated trajectories of teacher-reported warmth and conflict in their relationships with students 4years prior to and 3years following the transition to middle school in a sample of 550 academically at-risk and ethnically diverse adolescents. At the transition to middle school, teacher reports of warmth showed a significant drop (shift in intercept), above age-related declines. Both warmth and conflict declined across the middle school years. Structural equation modeling (SEM) tested effects of the shifts in intercept and the post-transition slopes on reading and math achievement, teacher-rated engagement, and student-reported school belonging 3years post-transition, above pre-transition levels of the outcome. For warmth, a drop in intercept predicted lower math scores and engagement, and a more positive slope predicted higher engagement. For conflict, an increase in intercept and a negative slope predicted lower engagement. Implications of findings for reducing normative declines in academic engagement in middle school are discussed. PMID- 29571531 TI - Harsh parenting and academic achievement in Chinese adolescents: Potential mediating roles of effortful control and classroom engagement. AB - This study examined (a) the potential mediating roles of effortful control and classroom engagement in the association between harsh parenting and adolescent academic achievement, and (b) the potential moderating role of gender. Sixth through eighth graders in rural China (n=815, mean age=12.55years) reported on harsh parenting, effortful control, and classroom engagement. Parents also reported on each other's harsh parenting. Academic achievement was assessed by students' test scores and teacher-rated academic performance. Results of structural equation modeling revealed gender differences in patterns of association among the model variables. Harsh parenting was negatively and directly associated with academic achievement for both boys and girls. It was also negatively and indirectly associated with academic achievement via effortful control and classroom engagement sequentially, forming a common indirect "path" for boys and girls. The indirect negative effect of harsh parenting on boys' academic achievement was mainly realized through the mediator of effortful control, whereas this same indirect effect for girls was mainly realized through the mediator of classroom engagement. Jointly, effortful control and classroom engagement precipitates more indirect effects for boys than for girls in the association between harsh parenting and academic achievement. The discussion analyzes the potential "paths" from harsh parenting to adolescent academic achievement, as well as gender differences in these "paths." The current study has implications for teachers and parents eager to improve students' classroom engagement and academic achievement. PMID- 29571532 TI - Chronic absence, eighth-grade achievement, and high school attainment in the Chicago Longitudinal Study. AB - Although not as commonly reported as average daily attendance, chronic absence data may be of significant importance for understanding student success. Using data from 1148 participants in the Chicago Longitudinal Study, we assessed the associations of chronic absence in the early middle grades, grades fourth through sixth, with eighth-grade achievement and three measures of high school attainment including four-year graduation by diploma, graduation by diploma by age 21, and any high school completion by age 21. The rate of chronic absenteeism, defined here as students missing approximately 14days of school or more in a year, was 15%. Using Ordinary Least Squares, probit regression, and inverse-probability weighting regression-adjustment methods (IPWRA), results indicated that chronic absence in the early middle grades was negatively associated (d=-0.17) with eighth-grade math achievement and reduced the probability of four-year graduation by diploma by 18 percentage points, graduation by diploma by age 21 by 17 percentage points, and any high school completion by age 21 by 11 percentage points. IPWRA yielded similar estimates. Coefficients varied by subgroup with males and children of mothers who completed high school experiencing more detrimental effects. Associations of chronic absence with outcomes are important to understand because school interventions and practices which begin early can be effective in reducing the prevalence of absenteeism. PMID- 29571533 TI - Comparison of progress monitoring data from general outcome measures and specific subskill mastery measures for reading. AB - Interventionists often monitor the progress of students receiving supplemental interventions with general outcome measures (GOMs) such as curriculum-based measurement of reading (CBM-R). However, some researchers have suggested that interventionists should collect data more closely related to instructional targets, specific subskill mastery measures (SSMMs) because outcomes from GOMs such as CBM-R may not be sufficiently sensitive to gauge intervention effects. In turn, interventionists may prematurely terminate an effective intervention or continue to deliver an ineffective intervention if they do not monitor student progress with the appropriate measure. However, such recommendations are based upon expert opinion or studies with serious methodological shortcomings. We used multi-variate multilevel modeling to compare pre-intervention intercepts and intervention slopes between GOM and SSMM data collected concurrently in a sample of 96 first, 44 second, and 53 third grade students receiving tier 2 phonics interventions. Statistically significant differences were observed between slopes from SSMM consonant-vowel-consonant words and CBM-R data. Statistically significant differences in slopes were not observed for consonant blend, digraph or consonant-vowel-consonant-silent e (CVCe) SSMMs. Results suggest that using word lists to monitor student response to instruction for early struggling readers is beneficial but as students are exposed to more complex phonetic patterns, the distinction between SSMMs and CBM-R become less meaningful. PMID- 29571534 TI - Informant similarities, twin studies, and the assessment of externalizing behavior: A meta-analysis. AB - The purpose of this study was to examine similarity within informant ratings of the externalizing behavior of monozygotic (MZ) and dizygotic (DZ) twin pairs. To do this, we conducted a meta-analysis of correlations within ratings completed by mothers, fathers, teachers, and youth. We retrieved n=204 correlations for MZ twins and n=267 correlations for DZ twins from n=54 studies containing n=55 samples. Results indicated that all four informants were significant negative predictors of within-informant correlations in their ratings of MZ, but not DZ twins. In the case of longitudinal studies and as the age of MZ twins increased, similarity within ratings by mothers was significantly greater than similarity within ratings by fathers. Among participant characteristics, we found that (a) age was a significant negative predictor of similarity within ratings for MZ twins; (b) race was a significant predictor of similarity within ratings for both MZ and DZ twins, but in the opposite direction; and (c) DZ opposite sex twins were a significant negative predictor of within-rating similarity. Among study characteristics for MZ twins, participant group and longitudinal study were significant negative predictors of within-rating similarity, and for both MZ and DZ twin pairs, non-independence in the data was a significant negative predictor of within-rating similarity. For DZ twins, multiple informants were significant positive predictors of within-rating similarity, and in longitudinal studies with DZ twins, similarity within ratings by mothers was significantly greater than similarity within ratings by fathers, and similarity within ratings by fathers was significantly less than similarity within ratings by teachers and youth. For both MZ and DZ twins, the following study characteristics were significant positive predictors of similarity within ratings: study group, number of time points, and multiple constructs. All four informants appeared equally skilled at predicting within-informant correlations for MZ (but not DZ) twins, with participant characteristics having different predictive effects for MZ compared to DZ twins, and study characteristics having comparable predictive effects for both twin types. Overall, these findings suggest effective discrimination on the part of four informants who rated the externalizing behavior of MZ and DZ twins. PMID- 29571535 TI - Associations between peer victimization, perceived teacher unfairness, and adolescents' adjustment and well-being. AB - Negative relationships within the classroom, both with peers and teachers, can be very stressful for adolescents and are often found to be associated with a variety of negative outcomes. In this study, we investigated the concurrent role of peer victimization and perceived teacher unfairness in explaining psychosocial problems in a sample of 1378 Italian students (353 middle school students, Mage=12.61, SD=0.69, and 1025 high school students, Mage=14.92, SD=0.81). Structural equation modeling showed that both peer victimization and perceived teacher unfairness were positively associated with reports of more frequent psychological and somatic problems, and negatively related to satisfaction with friends and sense of safety. Only perceived teacher unfairness showed a significant association with satisfaction with school. Results of multi-group modeling demonstrated measurement invariance (total scalar invariance) across both gender and school-level groups. Some gender and school-level differences in the regression coefficients were found. In general, associations between the risk factors and adolescents' problems were stronger for girls and for higher school students. Findings confirmed that both peer victimization and perceived teacher unfairness are significant risk factors within the classroom microsystems. Implications for school psychologists are discussed. PMID- 29571536 TI - Mentor Support Provisions Scale: Measure dimensionality, measurement invariance, and associations with adolescent school functioning. AB - Mentoring relationships can have important effects on adolescents' psychosocial and academic outcomes; however, the transactions within mentoring relationships that may account for impact on psychosocial and academic outcomes are not well understood. This study investigated the psychometric properties of the Mentor Support Provisions Scale (MSPS), a tool for assessing the types of support that mentors provide. Exploratory factor analyses and confirmatory factor analyses were used to determine measure dimensionality. Findings indicated acceptable fit with a three-factor structure: Academic Support, Intimacy, and Warmth. The MSPS was found to have scalar invariance; thus, factor loadings and intercepts are the same across student sex and ethnic groups (e.g., White, Hispanic, and Black). In structural equation modeling analyses, the three latent factors predicted academic engagement and reading and math achievement, above baseline scores. Research and practical uses of the MSPS are discussed. PMID- 29571537 TI - Improving outgroup attitudes in schools: A meta-analytic review. AB - To provide information for educators, educational psychologists, school psychologists, and social psychologists, we conducted a quantitative meta analytic test of n=50 studies dating from 1995 to 2015 that evaluated the effects of in-school interventions on attitudes toward outgroup members (defined as members of different ethnic or religious backgrounds or different age groups, persons with either physical or mental disabilities, or persons with other distinctive features). Overall, the analysis revealed a mean effect size of d+=0.36 with a 95% confidence interval that ranged from 0.17 to 0.55, indicating significant, moderate intervention effects, supporting the proposition that meaningful changes in outgroup attitudes can be obtained by applying anti-bias programs in schools. Results from our analysis did not provide evidence that teacher-led interventions produce positive outcomes, yet we found that interventions delivered by researchers promote positive attitudes toward outgroup members. Further, a closer examination demonstrated that one-on-one interventions are most effective at tackling intergroup attitudes. However, classroom-wide programs are more likely to be introduced into regular school activities because of their efficiency and the limited resources available for interventions. PMID- 29571538 TI - Efficacy of an exercise intervention among children with comorbid asthma and obesity. AB - OBJECTIVES: Children with comorbid asthma and obesity present with more severe and harder-to-control disease than asthmatic children at healthy weight. Weight loss has been shown to improve asthma symptoms, yet physical activity may be difficult due to exercise-induced bronchospasm. Children with asthma have lower exercise rates than non-asthmatics. The objective of this study was to retrospectively evaluate attrition rates and program outcome measures (Body Mass Index [BMI] and maximum oxygen consumption [VO2max]) among asthmatic and non asthmatic participants. STUDY DESIGN: Clinical data were collected from the Healthy Hearts Program, a 12-week nutrition and activity intervention program for children who are overweight, obese, or at risk for heart disease and other conditions, and used for the study. METHODS: Intervention data and demographics were obtained from medical records at the Children's Heart Center Nevada. Descriptive statistics, paired t-tests, Cox regression analysis, and analysis of covariance were conducted. RESULTS: The mean age of this population (N = 232) was 11 years; 54% were male, 64% were Hispanic, and 37% had asthma. Median time in the program was 9 weeks, and 58% of the population completed the program. Unadjusted analyses showed significant BMI decreases in asthmatic (P = 0.002) and non-asthmatic (P = 0.001) participants and increases in cardiorespiratory function for asthmatic males and females (P = 0.003, P = 0.004) and non-asthmatic males and females (P < 0.001 for both). Asthmatic and non-asthmatic children both had improved exercise intensity (P = 0.033, P < 0.001). CONCLUSIONS: This program is both beneficial and practical for obese children with asthma for losing weight and improving cardiorespiratory function.

PMID- 29571540 TI - What is the prevalence of cognitive impairment in lupus and which instruments are used to measure it? A systematic review and meta-analysis. AB - OBJECTIVES: To systematically review the literature on the prevalence of Cognitive Dysfunction (CD) in SLE patients in studies that used a specified neuropsychological instrument. METHODS: This review was prepared with a protocol following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols statement. Literature search in Ovid Medline, Embase, and Psyc INFO for articles on CD in adult SLE patients was conducted. Included studies were critically appraised (Newcastle-Ottawa Evaluation Scale) and the Pooled Prevalence (PP) of CD was studied for all instruments. The association between demographics and CD, the risk of CD in SLE compared to healthy subjects and patients with RA, and the course of CD over time were studied narratively whenever sufficient information was available. RESULT: Of 8054 references, 670 were selected for detailed review and 78 were included in the final analysis. Comprehensive Battery (CB) was utilized in 35 studies in 2463 SLE patients and PP was 38% (95%; CI: 33-43%). The CD prevalence was higher in NPSLE [PP 39% (95% CI: 24-55%]. Automated Neuropsychological Assessment Metric (ANAM) was utilized in 7 studies in 438 patients (PP of CD 26% (95% CI: 12-42%). Other less frequently utilized tools were the Modified Mini-Mental State Exam (MMSE), Montreal Cognitive Assessment (MoCA), Controlled Oral Word Association Test (COWAT) and The Hopkins Verbal Learning Test-Revised (HVLT-R) and subjective tools and others. The relative risk for CD in SLE was greater when compared to RA and to healthy individuals; RR being 1.80 and 2.80, respectively. Information on demographics and its association with CD was very heterogeneous among studies. CONCLUSION: Patients with lupus have a high prevalence of CD. The delay in diagnosis of CD is complex; although caregivers and patients express concerns about cognitive function, testing for CD often imposes administrative and cost burdens. There is an unmet need to identify the best screening, diagnostic metrics of CD. The assessment of cognitive function over time, and the association of demographics with CD, will require further research. PMID- 29571541 TI - New concept to describe three-phase capillary pressure-degree of saturation relationship in porous media. AB - The Leverett concept is used conventionally to model the relationship between the capillary pressures and the degrees of saturation in the water-nonaqueous phase liquid (NAPL)-air three-phase system in porous media. In this paper, the limitation of the Leverett concept that the concept is not applicable in the case of nonspreading NAPLs is discussed through microscopic consideration. A new concept that can be applied in the case of nonspreading NAPLs as well as spreading NAPLs is then proposed. The validity of the proposed concept is confirmed by comparing with past experimental data and simulation results obtained using the conventional model based on the Leverett concept. It is confirmed that the proposed concept can correctly predict the observed distributions of NAPLs, including those of nonspreading ones.

Non-supportive anatomy, cardio-respiratory and medical status, state control, neurologic functioning, postural stability and control, gastrointestinal functioning, hunger and satiation, developmental abilities, oral-motor skills, oral/pharyngeal reflexes, airway protection and secretion management can create barriers to successful oral feeding. Swallowing is broken down into four phases and difficulties can occur during any phase or in combination with another phase of swallowing. Dysphagia is diagnosed by both clinical and instrumental evaluation. Objective evaluations of swallowing include the Video Fluoroscopic Swallow Study (VFSS) and Fiberoptic Endoscopic Evaluation of Swallowing (FEES). A Video Fluoroscopic Swallow Study (VFSS) is a radiographic study assessing oropharyngeal swallow function. The Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is conducted by passing a laryngoscope through the nose to just below the soft palate for a "bird's eye view" of laryngeal anatomy and swallow function. Following a diagnosis of dysphagia from either a clinical or instrumental assessment, there are a variety of avenues that can be pursued including diet modifications, compensatory strategies, and use of specialized equipment to ensure a safe feeding plan and reduce the risk of aspiration. In conclusion, through numerous evaluation and intervention approaches, the contributions of SLPs helps provide input for well-rounded, multi-disciplinary plans supporting successful oral feeding. PMID- 29571544 TI - Chronic Pulmonary Aspiration in Children: Diagnosis and Management. AB - Chronic pulmonary aspiration (CPA) is a common cause of morbidity in children with complex aerodigestive disorders. CPA can be caused by swallowing dysfunction, anatomic, or dynamic abnormalities of the airways, and/or other circumstances that overcome the child's natural capacity to protect the airway. Diagnostic evaluation for suspected aspiration aims to characterize the swallowing function, identify the etiology of aspiration, including anatomic and/or dynamic abnormalities causing aspiration, and evaluate for the development of aspiration sequelae (e.g., bronchiectasis). CPA management approach should be guided by the recognized risk factors and co-morbidities, and directed to decrease the events of aspiration, improve clearance of aspirated material, and limit the development of aspiration sequelae (e.g., chronic inflammation and recurrent infections). This article presents a practical approach for the diagnosis and management of chronic pulmonary aspiration (CPA) in children. PMID- 29571545 TI - Diagnosis and Management of Laryngotracheoesophageal Cleft. AB - Laryngotracheoesophageal cleft (LTEC) is a rare anatomic cause of aspiration in the newborn and infant. The clinical presentation of infants with LTEC is variable and will usually vary with the degree of anatomic communication between the airway and esophagus. The diagnosis of LTEC is often challenging, particularly in cases where the presentation and pathology are more subtle. Management of LTEC depends upon the clinical presentation, degree of aspiration, and anatomic depth of the cleft. The goal of this review is to present the clinician with a practical approach to diagnosis and management of this rare but challenging congenital airway anomaly. PMID- 29571546 TI - Gastroesophageal Reflux Disease and Aerodigestive Disorders. AB - This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance. PMID- 29571547 TI - Eosinophilic Esophagitis. AB - Eosinophilic esophagitis (EoE) is a chronic allergic inflammatory disease of the esophagus that effects children and adults. Typical symptoms of EoE typically involve failure to thrive and vomiting in small children, and dysphagia and food impaction in adolescents and adults. However, throat clearing, choking, gagging, and hoarseness have also been observed and these issues often bring patients to first seek otolaryngology and pulmonary evaluation. Diagnosis is only made by esophogastroduodenoscopy with biopsy, so clinicians must have a low threshold for considering eosinophilic esophagitis even in the absence of frank gastrointestinal symptoms. PMID- 29571549 TI - Letter from the Editor: Abdominal Imaging. PMID- 29571548 TI - Analysis of chemosensory function in patients with chronic Eustachian tube dysfunction prior to and after balloon dilatation. AB - OBJECTIVE: Eustachian tube dysfunction (ETD) affects approximately 1% of adults in the general population. Non treated Eustachian tube dysfunction can result in chronic middle ear diseases, which have been shown to significantly affect taste sensitivity. A promising treatment is balloon dilatation of the Eustachian tube. The primary aim of the present study was to investigate whether individuals with ETD had impairment in chemosensory functions, and the changes of the chemosensory function after balloon dilatation of the Eustachian tube. METHODS: 26 patients (17 female, 9 male) (=56 ears) suffering from ETD with a mean age of 39+/-15years were included in the present study. 20 patients (76%) returned to be evaluated at the follow up (=40 ears) 51+/-22days after balloon dilatation. For pre- and post operation, gustatory function was measured with a lateralized gustatory test with the taste strips and olfactory function was tested by means of the Sniffin' Sticks test battery (threshold, discrimination and identification (ID)). RESULTS: Patients' baseline taste function (summed taste score 9.8+/-3.5 (mean+/-SD)) was significantly impaired compared to normative data (summed taste score 12.4+/-2.3; p=0.002). After balloon dilatation of the Eustachian tube, the taste function remained stable (summed taste score 9.4+/-4.3; p=0.814). Olfactory function (odor ID, summed score (TDI)) improved postoperatively (TDI 32.4+/-3.6) compared to pre operative scores (TDI 33.6+/-4.0; p=0.012), but not to a clinically relevant extent. CONCLUSION: This study suggests, that patients suffering from ETD exhibit reduced taste scores. Balloon dilatation of the Eustachian tube does not seem to influence gustatory function, but olfactory function showed improvement. PMID- 29571550 TI - CT Imaging of Emergent Renal Conditions. AB - The kidneys are paired intra-abdominal organs which provide essential functions and maintain homeostasis throughout the human body. Numerous disease processes affect the kidneys and cause acute renal dysfunction or other potentially catastrophic complications. These conditions can be broadly categorized into obstructive, infectious, hemorrhagic, traumatic, and vascular diseases. Imaging plays a vital role in the work-up and diagnosis of acute and emergent renal conditions. Evaluation of emergent renal conditions with a focus on CT imaging is discussed.

AB - Internal hernia in the postoperative laparoscopic Roux-en-Y patient is a diagnosis associated with significant morbidity and risk of death. The radiologist plays an instrumental role in workup of this patient group; however, the imaging assessment of these patients is not straightforward given their complex postsurgical anatomy. Multiple radiologic signs of internal hernia have been studied in the literature. This review article presents these signs with representative cases as well as a summary of their diagnostic accuracy. PMID- 29571552 TI - Imaging of Oncologic Emergencies. AB - Oncologic emergencies can be either the result of the primary tumor, its metastasis, a paraneoplastic syndrome or reaction to the chemotherapy. Imaging plays a crucial role in ensuring a prompt diagnosis as well as assisting in the therapeutic management. In this article, we discuss the common thoracic and abdominal oncological emergencies that may be encountered in an emergency department. PMID- 29571553 TI - Pneumatosis From Esophagus to Rectum: A Comprehensive Review Focusing on Clinico Radiological Differentiation Between Benign and Life-Threatening Causes. AB - Pneumatosis of the alimentary tract may occur from the esophagus to rectum as a result of a wide spectrum of conditions that range from benign to life threatening. Although distinguishing between these 2 groups is of paramount importance for an appropriate clinical management, it still remains a challenge for the radiologist in the daily practice. In the light of the current literature, we provide in the present article a comprehensive review focusing on the clinical, laboratory, and radiological findings that most consistently may allow such a differentiation. We also provide a pictorial essay illustrating this range of diagnoses, briefly discussing each one. PMID- 29571554 TI - Imaging Manifestations of Peptic Ulcer Disease on Computed Tomography. AB - Although the overall prevalence of peptic ulcer disease (PUD) has decreased in modern times, its actual incidence may be underestimated owing to the nonspecific clinical presentations patients' manifest. The potential lethal complications that can result from PUD include life-threatening abdominal hemorrhage and bowel perforation that result in significant morbidity and mortality. Computed tomography (CT) imaging historically lacks specificity in detecting PUD-related pathology in the stomach and proximal small bowel segments. Therefore, these are potential pitfalls in the radiologist's search pattern on abdominopelvic CT imaging. This article highlights imaging features of uncomplicated PUD on CT imaging in order to allow for early detection of this disease process on imaging and the prevention of potential high-grade complications by recommending esophagogastroduodenoscopy. PMID- 29571555 TI - Diffuse Liver Diseases: Role of imaging. AB - Nowadays, the most common imaging techniques allow to study focal liver lesions with high diagnostic accuracy but a relatively recent emerging field of interest is represented by diffuse liver disease. They include a variegated series of storage and metabolic pathologies (ie, iron overload disorders and steatosis) requiring a precise diagnosis not always possible at imaging due to the overlapping of findings at conventional ultrasound, CT, or MR studies. In recent years, several imaging tecniques and specific softwares have been developed, especially for ultrasound and MR imaging, in order to identify different parameters useful in the noninvasive recognition and follow-up of these diffuse processes involving the liver. The aim of this article is to describe the most common and useful imaging findings of the most common and uncommon diffuse liver diseases illustrating the newest imaging technologies and developments at our disposal with corresponding advantages, limitations, and pitfalls. PMID- 29571556 TI - Common and Uncommon Benign Pancreatic Lesions Mimicking Malignancy: Imaging Update and Review. AB - There is a broad range of inflammatory, pseudotumoral, and benign lesions that may masquerade as pancreatic malignancies, often representing a challenge to the radiologist. Unawareness of these entities can lead to inadequate differential diagnoses or misdiagnosis, with important prognostic and therapeutic consequences. The purpose of this article is to revisit a spectrum of lesions, varying from common to exceedingly rare nonmalignant, that may mimic malignant pancreatic neoplasms on imaging, identifying relevant features that may contribute to reaching the correct diagnosis. Representative cases include focal fatty replacement, intrapancreatic accessory spleen, pancreatic lobulation, lipoma, autoimmune pancreatitis, focal pancreatitis, eosinophilic pancreatitis, groove pancreatitis, hemangioma, intrapancreatic aneurysm, tuberculosis, and Castleman's disease. PMID- 29571557 TI - Computed Tomography and Magnetic Resonance Imaging Findings of Inflammatory Pseudotumors in the Abdomen and Pelvis: Current Concepts and Pictorial Review. AB - The group of inflammatory pseudotumors (IPTs) encompasses a variety of rare neoplastic and nonneoplastic entities described to occur in almost every location in the body and whose clinical features and aggressive imaging findings (varying from infiltrative to mass-forming lesions), frequently mimic those of malignant tumors. The radiologic features of IPTs are variable and nonspecific, the imaging findings depending on the body location and involved organ. Abdominopelvic IPTs are rare and the purposes of this review, therefore, are to familiarize the radiologist with the wide spectrum of computed tomography and magnetic resonance imaging findings of IPTs in various locations throughout the abdomen and pelvis, discussing the imaging features that allow consideration of IPTs in the differential diagnosis of soft-tissue masses within the pertinent clinical setting. Radiologists should be aware of this group of entities, as a preoperative histopathologic diagnosis upon radiological suspicion may help to differentiate IPTs from malignancy and to allow the most appropriate clinical work-up for these patients. PMID- 29571558 TI - Abdominal Wall Masses: CT Findings and Clues to Differential Diagnosis. AB - The abdominal wall does not comprise a distinct organ, and is often cursorily evaluated on CT. However, it is affected by many different pathological processes. These may be categorized according to their underlying etiology trauma, infection or inflammation, iatrogenic and neoplastic process-or according to the abdominal wall layer they affect. We chose instead to group these lesions into 6 distinct categories based on their CT characteristic density: solid, infiltrative, hypervascular, fluid, fat, and bone density lesions. We highlight throughout the article the importance of integrating pertinent clinical history to narrow the differential diagnosis. PMID- 29571559 TI - Otolaryngology in Low-Resource Settings: Practical and Ethical Considerations. AB - Providing otolaryngology care in low-resource settings requires careful preparation to ensure good outcomes. The level of care that can be provided is dictated by available resources and the supplementary equipment, supplies, and personnel brought in. Other challenges include personal health and safety risks as well as cultural and language differences. Studying outcomes will inform future missions. Educating and developing ongoing partnerships with local physicians can lead to sustained improvements in the local health care system. PMID- 29571560 TI - Otolaryngology Around the World. PMID- 29571561 TI - Absence of neurovascular conflict during microvascular decompression while treating essential trigeminal neuralgia. How to proceed? Systematic review of literature. AB - INTRODUCTION: Neurovascular conflict is the most accepted hypothesis for the cause for trigeminal neuralgia. Microvascular decompression of the trigeminal nerve is the most common surgical treatment for these patients. However, despite advances in diagnostic techniques, neurovascular conflict is sometimes not detected during surgery. The aim of this paper is to systematically review all the options available to best manage this scenario. RESULTS: Several techniques that could be used during microvascular decompression for trigeminal neuralgia in the absence of neurovascular conflict have been described. The success rates of these techniques, pain recurrence rates and rates of complications are also reported. Finally, we provide suggestions based on our experience. CONCLUSIONS: There is no gold standard, but several techniques could be successfully used in the absence of neurovascular conflict. The use of destructive techniques, such as PSR, should be held as treatments of last resort.

The MOOC entitled "Introduction to Histology, A Human Tissue Exploration" correspond to our vision of the practice of General Histology, which is based on the ability to diagnose 5 families of biological tissues. Ultimately, participants must be able to recognize the different types of cells and all the surrounding elements in order to understand how they organize themselves to form tissues with specific functions. A tool ! This know-how is based on reasoning from observations of microscopic structures. Learners are therefore invited to manipulate a virtual microscope to explore biological samples on histological slides digitized. Annotations, comments, drawings or photos are associated with landmarks that enrich the study of these histological sections. A target audience ! Two educational paths allow deepening the subject in a different way and thus matching the goals or motivations of each one. After a first year of experience, usage statistics and surveys of our learners show that the MOOC Histo has allowed each of them to find an interest and federate a community of motivated learners. PMID- 29571563 TI - [PD-L1 testing in non-small cell lung carcinoma: Guidelines from the PATTERN group of thoracic pathologists]. AB - Lung cancer is the leading cause of cancer death in France with low response rates to conventional chemotherapy. Nevertheless, new therapies have emerged recently, among which PD1 immune checkpoint inhibitors (ICI), such as nivolumab (OPDIVO(r), Bristol-Myers Squibb) and pembrolizumab (KEYTRUDA(r), Merck & Co), or PD-L1 ICI, such as atezolizumab (TECENTRIQ(r), Genentech), durvalumab (IMFINZI(r), Astra-Zeneca), and avelumab (BAVENCIO(r), EMD Serono). The prescription of pembrolizumab for advanced stage non-small cell lung carcinoma (NSCLC) patients requires the demonstration of PD-L1 expression by tumor cells by immunohistochemistry (IHC) (minimum of 50% of positive tumor cells is required for first-line setting, and of 1% for second-line and beyond) and PD-L1 assay is now considered as a companion diagnostic tool for this drug. Numerous standardized PD-L1 assays performed on dedicated platforms have been validated in clinical trials, each antibody being associated to one specific PD1 or PD-L1 inhibitor. However, not all pathologists have access to the dedicated platforms and the high cost of these assays is still a limitation to their implementation; in addition, the small size of the NSCLC tumor samples does not allow to perform at the same time multiple assays for multiple drugs. The use of laboratory developed tests seems feasible but their validation must guarantee the same sensitivities and specificities as standardized tests. In this context, the French group of thoracic pathologists PATTERN has teamed up with thoracic oncologists to provide recommendations on the indication, the critical technical steps and the interpretation of the PD-L1 IHC test to help pathologists to implement quickly and in the best conditions this new theranostic test. PMID- 29571564 TI - Balance and lower limb loads distribution after Ilizarov corticotomy. AB - INTRODUCTION: Normal balance and symmetric distribution of lower limb loads are associated with adequate muscle strength, joint mobility and proprioception. The aim of this study was to analyze the distribution of lower limb loads and balance prior to and after axis correction and lengthening with Ilizarov method. MATERIALS AND METHODS: The prospective analysis included 20 patients from our clinic, who have been subjected to distraction-corrective lower limb corticotomies with the Ilizarov method in 2014-2015. Balance and distribution of lower limb loads were determined with a pedobarographic platform. RESULTS: Prior to the surgery, mean loads on affected and non-affected limbs corresponded to42%and58%of body weight, respectively. Mean loads on affected and non-affected limbs during the postoperative examination did not differ significantly. Mean path length of the center of gravity prior to and after the surgery amounted to143.27 cm and 125.11 cm, respectively. Mean area of the center of gravity was 7.81 cm2prior to the surgery and 5.81 cm2after the procedure. DISCUSSION: Our present study showed that distraction-corrective Ilizarov corticotomy may provide more symmetric distribution of lower limb loads and improvement of balance. This outcome should be considered satisfactory from the perspective of the locomotor system statics. Corticotomies with Ilizarov method provide symmetric distribution of loads between non-affected and operated limb. PMID- 29571566 TI - High intake of orange juice and cola differently affects metabolic risk in healthy subjects. AB - BACKGROUND: Higher consumption of sugar-containing beverages has been associated with an elevated risk of type 2 diabetes and gout. Whether this equally applies to cola with an unhealthy image and orange juice (OJ) having a healthy image remains unknown. METHODS: In order to investigate whether OJ and cola differently affect metabolic risk 26 healthy adults (24.7 +/- 3.2 y; BMI 23.2 +/- 3.3 kg/m2) participated in a 2 * 2-wk intervention and consumed either OJ or caffeine-free cola (20% Ereq as sugar from beverages) in-between 3 meals/d at ad libitum energy intake. Glycemic control, uric acid metabolism and gut microbiota were assessed as outcome parameters. RESULTS: Fecal microbiota, body weight, basal and OGTT derived insulin sensitivity remained unchanged in both intervention periods. Levels of uric acid were normal at baseline and did not change with 2-wk cola consumption (-0.03 +/- 0.67 mg/dL; p > 0.05), whereas they decreased with OJ intervention (-0.43 +/- 0.56 mg/dL; p < 0.01) due to increased uric acid excretion (+130.2 +/- 130.0 mg/d; p < 0.001). Compared to OJ, consumption of cola led to a higher daylong glycemia (DeltaiAUC: 36.9 +/- 83.2; p < 0.05), an increase in glucose variability (DeltaMAGE-Index: 0.29 +/- 0.44; p < 0.05), and a lower 24 h-insulin secretion (DeltaC-peptide excretion: -31.76 +/- 38.61 MUg/d; p < 0.001), which may be explained by a decrease in serum potassium levels (-0.11 +/- 0.24 mmol/L; p < 0.05). CONCLUSION: Despite its sugar content, regular consumption of large amounts of OJ do not increase the risk of gout but may even contribute to lower uric acid levels. The etiology of impaired insulin secretion with cola consumption needs to be further investigated. PMID- 29571565 TI - Heritability of the timing of food intake. AB - BACKGROUND & AIMS: While environmental factors are presumed to be primary drivers of food timing, preliminary evidence suggests that genetics may be an additional determinant. The aim was to explore the relative contribution of genetics and environmental factors to variation in the timing of food intake in a Spanish twin population. Because chronotype, bedtime and wake time are related to food timing, covariance with food timing was further assessed. METHODS: In this observational study, 53 pairs of adult (mean (SD) = 52 (6.03) years) female twins (28 monozygotic; 25 dizygotic) were recruited from the Murcia Twin Register. Zygosity was determined by DNA-testing. Timing of the three main meals of the day was assessed via 7-day dietary records, and the midpoint of food intake was computed by calculating the midpoint between breakfast and dinner times. Chronotype, bedtime and wake time were self-reported. Heritability of food timing and related traits were estimated by comparing monozygotic and dizygotic twin correlations and fitting genetic structural equation models to measured variables. RESULTS: We observed genetic influences for food timing, with highest heritability for the midpoint of food intake (64%) in an overweight/obese population (BMI = 26.01 +/- 3.77). Genetic factors contributed to a higher degree to the timing of breakfast (56%) than the timing of lunch (38%) or dinner (n.s.). Similarly, heritability estimates were larger in related behavioral traits earlier on in the day (i.e. wake time, (55%)), than those later on in the day (i.e. bedtime, (38%)). Bivariate analyses revealed a significant genetic overlap between food timing and bedtime and chronotype (rG between 0.78 and 0.91). CONCLUSIONS: Genetic influences appear to account for a significant proportion of the variability in food timing, particularly breakfast. Thus, interventions related to food timing may be more effective when targeting afternoon/evening traits, such as lunch or dinner times. Furthermore, our data suggest shared genetic architecture underlying food timing and phenotypically related traits. CLINICAL TRIAL: NCT03059576. https://clinicaltrials.gov/ct2/show/NCT03059576. PMID- 29571567 TI - Palliative Care for People With Hepatocellular Carcinoma, and Specific Benefits for Older Adults. AB - PURPOSE: Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, has a rapidly rising prevalence in the United States and a very poor overall rate of survival. This epidemic is driven by the cohort of aging Baby Boomers with hepatitis C viral infection and the increasing prevalence of cirrhosis as a result of nonalcoholic steatohepatitis. Because curative options are limited, the disease course creates, in patients and their families, distressing uncertainty around prognosis and treatment decisions. Older adults are disproportionately affected by HCC and have more comorbidities, adding to the complexity of the disease. This population would benefit from increased access to palliative care services, which can potentially complement the treatments throughout the disease trajectory. The purpose of this review was to use existing evidence to propose a new model of palliative care integration in patients with HCC. Thus, we focus on the HCC stage and the treatment algorithm, the ways that palliative care can offer support in this population at each stage, as well as elements that can enhance patient and family support throughout the entire disease trajectory, with an emphasis on the care of older adults with HCC. METHODS: This is a narrative review in which we identify evidence-based ways that palliative care can help younger and older adults with HCC and their families, at each stage of HCC and throughout the disease trajectory. FINDINGS: We propose ways to integrate HCC and palliative care based on the existing evidence in both fields. Palliative care offers support in symptom management, advanced care planning, and decision making in ways that are specific to each stage of HCC. We also discuss the evidence that illustrates the palliative care needs of patients with HCC that span the entire course of illness, including coping with the stigmatization of liver disease, addressing informational needs at different stages, and discussing quality of life longitudinally. IMPLICATIONS: Integrating palliative care into the treatment of patients with HCC has the potential to improve outcomes, although more research is needed to build this evidence base. PMID- 29571568 TI - Copper (II) addition to accelerate lactic acid production from co-fermentation of food waste and waste activated sludge: Understanding of the corresponding metabolisms, microbial community and predictive functional profiling. AB - Bio-refinery of food waste and waste activated sludge to high value-added chemicals, such as lactic acid, has attracted particular interest in recent years. In this paper, the effect of copper (II) dosing to the organic waste fermentation system on lactic acid production was evaluated, which proved to be a promising method to stimulate high yield of lactic acid (77.0% higher than blank) at dosage of 15 MUM-Cu2+/g VSS. As mechanism study suggested, copper addition enhanced the activity of alpha-glycosidase and glycolysis, which increased the substrate for subsequent acidification; whereas, the high dosage (70 MUM-Cu2+/g VSS) inhibited the conversion of lactic acid to VFA, thus stabilized lactic acid concentration. Microbial community study revealed that small amount of copper (II) at 15 MUM/g VSS resulted in the proliferation of Lactobacillus to 82.6%, which mainly produced lactic acid. Finally, the variation of functional capabilities implied that the proposed homeostatic system II was activated at relatively low concentration of copper. Meanwhile, membrane transport function and carbohydrate metabolism were also strengthened. This study provides insights into the effect of copper (II) on the enhancement of lactic acid production from co-fermentation of food waste and waste activated sludge. PMID- 29571569 TI - Life cycle assessment of integrated solid state anaerobic digestion and composting for on-farm organic residues treatment. AB - Driven by the gradual changes in the structure of energy consumption and improvements of living standards in China, the volume of on-farm organic solid waste is increasing. If untreated, these unutilized on-farm organic solid wastes can cause environmental problems. This paper presents the results of a life cycle assessment to compare the environmental impacts of different on-farm organic waste (which includes dairy manure, corn stover and tomato residue) treatment strategies, including anaerobic digestion (AD), composting, and AD followed by composting. The input life cycle inventory data are specific to China. The potential environmental impacts of different waste management strategies were assessed based on their acidification potential (AP), eutrophication potential (EP), global warming potential (GWP), ecotoxicity potential (ETP), and resource depletion (RD). The results show that the preferred treatment strategy for dairy manure is the one that integrated corn stover and tomato residue utilization and solid state AD technologies into the system. The GWP of integrated solid state AD and composting was the least, which is -2900 kg CO2 eq/ t of dairy manure and approximately 14.8 times less than that of current status (i.e., liquid AD of dairy manure). Solid state AD of dairy manure, corn stover and tomato residues is the most favorable option in terms of AP, EP and ETP, which are more than 40% lower than that of the current status (i.e., AP: 3.11 kg SO2, EP: -0.94 kg N, and ETP: -881 CTUe (Comparative Toxic Units ecotoxicity)). The results also show that there is a significant potential for AP, EP, ETP, and GWP reduction, if AD is used prior to composting. The scenario analysis for transportation distance showed that locating the AD plant and composting facility on the farm was advantageous in terms of all the life cycle impact categories. PMID- 29571570 TI - Inside the small-scale composting of kitchen and garden wastes: Thermal performance and stratification effect in vertical compost bins. AB - Decentralized composting has been proposed as a best available practice, with a highly positive impact on municipal solid wastes management plans. However, in cold climates, decentralized small-scale composting performance to reach thermophilic temperatures (required for the product sanitization) could be poor, due to a lack of critical mass to retain heat. In addition, in these systems the composting process is usually disturbed when new portions of fresh organic waste are combined with previous batches. This causes modifications in the well-known composting evolution pattern. The objective of this work was to improve the understanding of these technical aspects through a real-scale decentralized composting experience carried out under cold climate conditions, in order to assess sanitization performance and to study the effects of fresh feedstock additions in the process evolution. Kitchen and garden organic wastes were composted in 500 L-static compost bins (without turning) for 244 days under cold climate conditions (Bariloche, NW Patagonia, Argentina), using pine wood shavings in a ratio of 1.5:1 v: v (waste: bulking agent). Temperature profile, stability indicators (microbial activity, carbon and nitrogen contents and ratio) and other variables (pH and electrical conductivity), were monitored throughout the experience. Our results indicate that small-scale composting (average generation rate of 7 kg d-1) is viable under cold weather conditions, since thermophilic sanitization temperatures (> 55 degrees C) were maintained for 3 consecutive days in most of the composting mass, according to available USEPA regulations commonly used as a reference for pathogens control in sewage sludge. On the other hand, stability indicators showed a differentiated organic matter degradation process along the compost bins height. Particularly, in the bottommost composting mix layer the process took a longer period to achieve compost stability than the upper layers, suggesting that differential organic matter transformation appears not to be necessarily associated to the order of the waste batches incorporation in a time line, as it could be expected. These findings suggest the need to discuss new ways of studying the composting process in small-scale compost bins as well as their commercial design. PMID- 29571571 TI - Disulfiram-based disulfides as narrow-spectrum antibacterial agents. AB - Sixteen disulfides derived from disulfiram (AntabuseTM) were evaluated as antibacterial agents. Derivatives with hydrocarbon chains of seven and eight carbons in length exhibited antibacterial activity against Gram-positive Staphylococcus, Streptococcus, Enterococcus, Bacillus, and Listeria spp. A comparison of the cytotoxicity and microsomal stability with disulfiram further revealed that the eight carbon chain analog was of lower toxicity to human hepatocytes and has a longer metabolic half-life. In the final analysis, this investigation concluded that the S-octylthio derivative is a more effective growth inhibitor of Gram-positive bacteria than disulfiram and exhibits more favorable cytotoxic and metabolic parameters over disulfiram. PMID- 29571572 TI - Design, synthesis, and evaluation of l-cystine diamides as l-cystine crystallization inhibitors for cystinuria. AB - To overcome the chemical and metabolic stability issues of l-cystine dimethyl ester (CDME) and l-cystine methyl ester (CME), a series of l-cystine diamides with or without Nalpha-methylation was designed, synthesized, and evaluated for their inhibitory activity of l-cystine crystallization. l-Cystine diamides 2a-i without Nalpha-methylation were found to be potent inhibitors of l-cystine crystallization while Nalpha-methylation of l-cystine diamides resulted in derivatives 3b-i devoid of any inhibitory activity of l-cystine crystallization. Computational modeling indicates that Nalpha-methylation leads to significant decrease in binding of the l-cystine diamides to l-cystine crystal surface. Among the l-cystine diamides 2a-i, l-cystine bismorpholide (CDMOR, LH707, 2g) and l cystine bis(N'-methylpiperazide) (CDNMP, LH708, 2h) are the most potent inhibitors of l-cystine crystallization.

AB - Globally, vibrios represent an important and well-established group of bacterial foodborne pathogens. The European Commission (EC) mandated the Comite de European Normalisation (CEN) to undertake work to provide validation data for 15 methods in microbiology to support EC legislation. As part of this mandated work programme, merging of ISO/TS 21872-1:2007, which specifies a horizontal method for the detection of V. parahaemolyticus and V. cholerae, and ISO/TS 21872 2:2007, a similar horizontal method for the detection of potentially pathogenic vibrios other than V. cholerae and V. parahaemolyticus was proposed. Both parts of ISO/TS 21872 utilized classical culture-based isolation techniques coupled with biochemical confirmation steps. The work also considered simplification of the biochemical confirmation steps. In addition, because of advances in molecular based methods for identification of human pathogenic Vibrio spp. classical and real-time PCR options were also included within the scope of the validation. These considerations formed the basis of a multi-laboratory validation study with the aim of improving the precision of this ISO technical specification and providing a single ISO standard method to enable detection of these important foodborne Vibrio spp.. To achieve this aim, an international validation study involving 13 laboratories from 9 countries in Europe was conducted in 2013. The results of this validation have enabled integration of the two existing technical specifications targeting the detection of the major foodborne Vibrio spp., simplification of the suite of recommended biochemical identification tests and the introduction of molecular procedures that provide both species level identification and discrimination of putatively pathogenic strains of V. parahaemolyticus by the determination of the presence of theromostable direct and direct related haemolysins. The method performance characteristics generated in this have been included in revised international standard, ISO 21872:2017, published in July 2017.

AB - INTRODUCTION: Vaccination against influenza virus and Streptococcus pneumoniae is a global health priority and authorities, on the basis of recent publications, have recently updated French recommendations. The aim of this study was to describe the influenzae and pneumococcal vaccination's rate in an internal medicine ward. MATERIAL AND METHODS: All patients consecutively hospitalized during a 10 week-period in an internal medicine ward were included. The reasons for non-vaccination and the impact of an educational program for corrective measures were reported. RESULTS: Overall, 198 consecutive patients were included; 93 (47%) were immunocompromised; 142 (71.2%) had an indication for pneumococcal vaccination and 171 (86.4%) for influenza vaccination but only 16.2% and 55% of them were vaccinated against these microorganisms, respectively. Prior pneumococcal vaccination was more frequently observed in immunocompromised patients than in non-immunocompromised patients (21.1 versus 6.4%; P=0.029), but no significant difference was observed for influenza vaccine. Corrective measures were initiated in 46 patients (39%), non-immunized against S. pneumoniae. CONCLUSION: These results underline the very low prevalence of pneumococcal vaccination rate in at-risk hospitalized patients, as compared with influenza, despite recent recommendations.

AB - This paper proposed the distributed moving horizon coordinated control scheme for the power balance and economic dispatch problems of micro-grid based on distributed generation. We design the power coordinated controller for each subsystem via moving horizon control by minimizing a suitable objective function. The objective function of distributed moving horizon coordinated controller is chosen based on the principle that wind power subsystem has the priority to generate electricity while photovoltaic power generation coordinates with wind power subsystem and the battery is only activated to meet the load demand when necessary. The simulation results illustrate that the proposed distributed moving horizon coordinated controller can allocate the output power of two generation subsystems reasonably under varying environment conditions, which not only can satisfy the load demand but also limit excessive fluctuations of output power to protect the power generation equipment.

AB - In this paper, we address the problem of reachable set estimation for continuous time Takagi-Sugeno (T-S) fuzzy systems subject to unknown output delays. Based on the reachable set concept, a new controller design method is also discussed for such systems. An effective method is developed to attenuate the negative impact from the unknown output delays, which likely degrade the performance/stability of systems. First, an augmented fuzzy observer is proposed to capacitate a synchronous estimation for the system state and the disturbance term owing to the unknown output delays, which ensures that the reachable set of the estimation error is limited via the intersection operation of ellipsoids. Then, a compensation technique is employed to eliminate the influence on the system performance stemmed from the unknown output delays. Finally, the effectiveness and correctness of the obtained theories are verified by the tracking control of autonomous underwater vehicles. PMID- 29571585 TI - Molecular Progression Risk Score for Prediction of Muscle Invasion in Primary T1 High-Grade Bladder Cancer. AB - BACKGROUND: Pathologic T1 high-grade (pT1HG) bladder cancer (BC) is characterized by a high progression rate and constitutes an important clinical challenge; however, there is no consensus on the prediction of progression in pT1HG BC. The purpose of this study was to validate previously published molecular progression risk score (MoPRS) for predicting muscle-invasive disease in pT1HG BC. MATERIALS AND METHODS: The expression of an 8-gene progression-related classifier identified from microarray data was analyzed by real-time PCR, and the MoPRS was calculated in 121 newly recruited patients with pT1HG BC. Progression was defined as muscle invasion or metastasis. RESULTS: Overall, the disease of 28 patients (23.1%) progressed to muscle-invasive BC during the median follow-up of 63.7 (interquartile range, 17.6-96.4) months. The MoPRS was significantly higher in 1973 World Health Organization grade 3 than grade 2 tumors (P = .004). Early development of invasive BC was more prevalent in the highest quartile MoPRS group than in the lowest to 75th percentile MoPRS groups according to Kaplan-Meier analysis. Multivariate Cox regression analysis revealed that the MoPRS was an independent predictor of invasive BC, either as a continuous variable (hazard ratio, 1.624; 95% confidence interval, 1.266-2.082; P < .001) or as a categorical variable (hazard ratio, 3.089; 95% confidence interval, 1.335-7.150; P = .008). CONCLUSION: The MoPRS was an independent prognostic factor for identifying patients at high risk of invasive BC in patients with pT1HG BC. This scale may help identify patients who could benefit from more aggressive therapeutic intervention such as early cystectomy. PMID- 29571584 TI - Using Genetic and Epigenetic Markers to Improve Differential Diagnosis of Prostate Cancer and Benign Prostatic Hyperplasia by Noninvasive Methods in Mexican Patients. AB - BACKGROUND: Prostate cancer (PCa) is the most common malignancy in Mexican men. Serum prostate-specific antigen (PSA) is the usual noninvasive biomarker used for its detection. Its low specificity can increase the number of unnecessary prostate biopsies and the incidence of unpleasant complications for patients. The androgen-receptor gene (AR-CAG) repeat length and the percentage of promoter methylation (PPM) of genes glutathione-S-transferase P1 (GSTP1) and Ras association domain family 1 isoform A (RASSF1A) improve PCa detection. As an option for noninvasive assessment, we evaluated a combined analysis of all these biomarkers. PATIENTS AND METHODS: A total of 186 patients scheduled for biopsy were included in the present study. PSA and AR-CAG repeats were analyzed in blood samples. The PPM of GSTP1 and RASSF1A genes was estimated in prostate tissue and urinary sediment cells (USCs) and plasma DNA using quantitative methylation specific polymerase chain reaction. The predictive values for PCa and benign prostatic hyperplasia (BPH), logistic regression analysis, receiver operating characteristic curve, and decision curve analysis were used to assess the differential diagnosis. RESULTS: Statistically significant differences between PCa and BPH patients were observed for all biomarkers, with higher positive and negative predictive values when all biomarkers were included in the analysis, attaining USC values of 89.2% and 78.0%, respectively. The differential diagnosis accuracy of PSA (area under the curve, 0.59) increased to 0.70 and 0.68, respectively, when the combined analysis of PPM of RASSF1Aplasma or GSTP1AUSC and AR-CAG repeats was performed. Decision curve analysis showed the utility of the combined analysis to decrease the number of unnecessary biopsies. CONCLUSION: The results showed that combined analysis of the proposed biomarkers in plasma and USCs significantly increased the confidence for the differential diagnosis for PCa and BPH. This noninvasive practice might help in the early detection of PCa and patient follow-up, avoiding to some extent unnecessary prostate biopsies. PMID- 29571586 TI - Personalized Transcranial Magnetic Stimulation in Psychiatry. AB - Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that allows for modulating the activity of local neural populations and related neural networks. TMS is touted as a viable intervention to normalize brain activity and alleviate some psychiatric symptoms. However, TMS interventions are known to be only moderately reliable, and the efficacy of such therapies remains to be proven for psychiatric disorders other than depression. We review new opportunities to personalize TMS interventions using neuroimaging and computational modeling, aiming to optimize treatment to suit particular individuals and clinical subgroups. Specifically, we consider the prospect of improving the efficacy of existing TMS interventions by parsing broad diagnostic categories into biologically and clinically homogeneous biotypes. Biotypes can provide distinct treatment targets for optimized TMS interventions. We further discuss the utility of computational models in refining TMS personalization and efficiently establishing optimal cortical targets for distinct biotypes. Personalizing cortical stimulation targets, treatment frequencies, and intensities can improve the therapeutic efficacy of TMS and potentially establish noninvasive brain stimulation as a viable treatment for psychiatric symptoms.

AB - The Florida stone crab, Menippe mercenaria, is a major commercial fishery that occurs primarily along Florida's west coast, where harmful algal blooms of Karenia brevis frequently develop. To determine sublethal and lethal effects of K. brevis on M. mercenaria, we exposed sublegal stone crabs to three seawater treatments in laboratory conditions: no K. brevis (control), a low-toxin K. brevis strain (Wilson LT), and a toxic K. brevis (New Pass strain). Total food consumed, reflex impairment and survivorship of each crab was monitored throughout the nine-day experiment. Crabs in the toxic treatment consumed 67% less food. The probability of an individual losing a reflex significantly increased with time (days), and there was a 42% decrease in survivorship in the toxic treatment. This is the first study to demonstrate negative effects of K. brevis on the stone crab, presenting the critical need of further investigation to fully understand how red tide may impact sustainability of the fishery. PMID- 29571588 TI - Settlement performance of the Mediterranean reef-builders Dendropoma cristatum (Biondi 1859) in response to natural bacterial films. AB - The gastropod Dendropoma cristatum is a biogenic engineer of the central Mediterranean, forming reefs along the lower rocky intertidal fringe with a remarkable ecological role. To understand whether reef-associated biofilm cultivable bacterial and biofilm ageing may trigger the settlement of the juvenile snails, a combination of laboratory techniques and field experiments was used. Reef-associated biofilm cultivable bacteria were isolated, and a settlement choice experiment was performed in situ on artificial biofilms composed of i) a mixture of six biofilm-forming selected isolates, ii) all the cultivable bacteria, and iii) 13-, 23-, 32-day old biofilms formed under natural conditions. Overall, settlement rate significantly differed among biofilm treatments (p < 0.0001). A significant positive correlation between biofilm ageing and juvenile D. cristatum settlement was assessed (r = 0.69 (p < 0.001), whereas the biofilm bacterial composition (relatively to the cultivable fraction) did not show any effect on the vermetid's settlement rate. PMID- 29571589 TI - Impact of weight loss on epicardial fat and carotid intima media thickness after laparoscopic sleeve gastrectomy: A prospective study. AB - BACKGROUND AND AIMS: Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis. METHODS AND RESULTS: Patients were recruited for standard indications. A total of 105 patients (79 women and 26 men) with the mean age of 43.61 +/- 12.42 were prospectively enrolled. On B-mode duplex ultrasound; the mean CIMT at the far wall of both left and right common carotid arteries were measured. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Delta (Delta) values were obtained by subtracting sixth month values from the baseline values. Body mass index (BMI) was significantly reduced from 46.95 +/- 7.54 to 33.54 +/- 6.41 kg/m2 (p < 0.001) in sixth months after LSG. Both EFT and CIMT were significantly decreased after surgery (8.68 +/- 1.95 mm vs. 7.41 +/- 1.87 mm; p < 0.001 and 0.74 +/- 0.13 mm vs. 0.67 +/- 0.11 mm; p < 0.001 respectively). A significant correlation between DeltaEFT and DeltaBMI (r = 0.431, p < 0.001) was shown. DeltaCIMT is significantly correlated with DeltaEFT, DeltaBMI and Delta systolic blood pressure (r = 0.310, r = 0.285 and r = 0.231 respectively, p < 0.05 for all). In multivariate stepwise linear regression analysis; among variables only DeltaBMI was the independent predictor of DeltaEFT (beta = 153, p = 0.001). CONCLUSION: Early atherosclerotic structural changes may be reversed or improved by sustained weight loss after LSG in asymptomatic obese patients. PMID- 29571590 TI - Cardiovascular risk biomarkers and metabolically unhealthy status in prepubertal children: Comparison of definitions. AB - BACKGROUND AND AIMS: The early onset of cardio-metabolic abnormalities, known as metabolically unhealthy (MU) status, is highly associated with obesity and cardiovascular disease (CVD), as well as with increased morbidity and mortality later in life. Given the lack of a consensus MU classification for prepubertal children, we aimed to compare available MU definitions in terms of their association with CVD risk biomarkers. METHODS AND RESULTS: A total of 930 prepubertal children (622 with overweight/obesity, 462 males) aged 5-10.9 years were recruited, anthropometric measures were taken and biomarkers were analyzed. Children were classified using eight MU definitions based on different cut-offs for blood pressure, triacylglycerides, high-density lipoprotein cholesterol, glucose and homeostasis model assessment for insulin resistance (HOMA-IR). MU prevalence in children with overweight/obesity ranged between 30% and 60% across definitions. Plasma concentrations of resistin, leptin, myeloperoxidase (MPO) and total plasminogen activator inhibitor 1 (tPAI-1) were higher, and those of adiponectin were lower, in MU compared to MH children with overweight/obesity. Linear regression analyses confirmed the contribution of MPO and tPAI-1 concentrations to MU status, with most significant results derived from definitions that use age and sex-specific criteria and that account for HOMA-IR. CONCLUSION: Plasma concentrations of MPO and tPAI-1 are increased in prepubertal MU children irrespective of having normal-weight or overweight/obesity. Inclusion of age and sex-specific cut-offs for cardio-metabolic components as well as insulin resistance criteria increases the quality of MU definitions as seen by their stronger association with CVD biomarkers concentrations.

AB - BACKGROUND: Anaemia affects as many as half of all pregnant women in low-income and middle-income countries, but the burden of disease and associated maternal mortality are not robustly quantified. We aimed to assess the association between severe anaemia and maternal death with data from the WHO Multicountry Survey on maternal and newborn health. METHODS: We used multilevel and propensity score regression analyses to establish the relation between severe anaemia and maternal death in 359 health facilities in 29 countries across Latin America, Africa, the Western Pacific, eastern Mediterranean, and southeast Asia. Severe anaemia was defined as antenatal or postnatal haemoglobin concentrations of less than 70 g/L in a blood sample obtained before death. Maternal death was defined as death any time after admission until the seventh day post partum or discharge. In regression analyses, we adjusted for post-partum haemorrhage, general anaesthesia, admission to intensive care, sepsis, pre-eclampsia or eclampsia, thrombocytopenia, shock, massive transfusion, severe oliguria, failure to form clots, and severe acidosis as confounding variables. These variables were used to develop the propensity score. FINDINGS: 312 281 women admitted in labour or with ectopic pregnancies were included in the adjusted multilevel logistic analysis, and 12 470 were included in the propensity score regression analysis. The adjusted odds ratio for maternal death in women with severe anaemia compared with those without severe anaemia was 2.36 (95% CI 1.60-3.48). In the propensity score analysis, severe anaemia was also associated with maternal death (adjusted odds ratio 1.86 [95% CI 1.39-2.49]). INTERPRETATION: Prevention and treatment of anaemia during pregnancy and post partum should remain a global public health and research priority. FUNDING: Barts and the London Charity.

PMID- 29571595 TI - "Sedation is tricky": A qualitative content analysis of nurses' perceptions of sedation administration in mechanically ventilated intensive care unit patients. AB - INTRODUCTION: Critical care nurses are responsible for administering sedative medications to mechanically ventilated patients. With significant advancements in the understanding of the impact of sedative exposure on physiological and psychological outcomes of ventilated patients, updated practice guidelines for assessment and management of pain, agitation, and delirium in the intensive care unit were released in 2013. The primary aim of this qualitative study was to identify and describe themes derived from critical care nurses' comments regarding sedation administration practices with mechanically ventilated patients. METHODS: This is a qualitative content analysis of secondary text data captured through a national electronic survey of members of the American Association of Critical-Care Nurses. A subsample (n = 67) of nurses responded to a single, open-ended item at the end of a survey that evaluated nurses' perceptions of current sedation administration practices. FINDINGS: Multiple factors guided sedation administration practices, including individual patient needs, nurses' synthesis of clinical evidence, application of best practices, and various personal and professional practice perspectives. Our results also indicated nurses desire additional resources to improve their sedation administration practices including more training, better communication tools, and adequate staffing. CONCLUSIONS: Critical care nurses endorse recommendations to minimise sedation administration when possible, but a variety of factors, including personal perspectives, impact sedation administration in the intensive care unit and need to be considered. Critical care nurses continue to encounter numerous challenges when assessing and managing sedation of mechanically ventilated patients. PMID- 29571594 TI - Occurrence of neoplasms in individuals with congenital, severe GH deficiency from the Itabaianinha kindred. AB - Growth hormone (GH) and the insulin-like growth factor I (IGF-I) have cell proliferative and differentiation properties. Whether these hormones have a role in mutagenesis is unknown. Nevertheless, severe IGF-I deficiency seems to confer protection against the development of neoplasms. Here, we report five cases of adult patients with severe and congenital isolated GH deficiency (IGHD) due to the c.57+1G>A mutation in the GHRH receptor gene, who developed tumors. Four GH naive subjects presented skin tumors: a 42-year-old man with a fibroepithelial polyp, a 53-year-old woman and two men (59 and 56 years old) with epidermoid skin cancers. One of these died from it after three surgeries and radiotherapy. The fifth patient was a 25-year-old woman, who had intermittently received GH replacement therapy (GHRT) from age 11 to 18, who developed an ependymoma extending from the fourth ventricle to the end of the thoracic spine. She underwent three surgical procedures, without obvious evidence of tumor recurrence during the six years follow up. These observations suggest that severe IGHD does not protect completely from development of tumors. PMID- 29571596 TI - Bereaved parents' experiences of the police in the paediatric intensive care unit. AB - BACKGROUND: A child's death in the intensive care unit is often sudden and unexpected, requiring the involvement of the state coroner to investigate both the cause and the circumstances surrounding the death. This process often involves the police, who arrive in intensive care to identify the body and collect statements from the parents. At present, very little is known about parents' experiences of this process. OBJECTIVES: To explore bereaved parents' experiences of police presence in intensive care, as part of routine coronial investigations. The findings arose from a larger study on bereaved parents' experiences of the death of a child in the intensive care unit. METHODS: Secondary analysis of incidental data from a larger grounded theory study. Nine bereaved parents from two paediatric intensive care units (PICUs) mentioned police presence in the PICU during their original audio-recorded, semistructured interviews. These data were extracted, and thematic analysis techniques were used to identify key themes. RESULTS: Three main concepts were identified with the parents' experiences: (i) timing of police interviews; (ii) the impacts of police presence; and (iii) the demeanour of the officers. Overall, the parents' experiences of police presence were negative. They felt that police arrived too soon after their child's death and took too long taking their statements, hindering their ability to say goodbye. The presence of police officers also made parents feel as though they were being accused of involvement in their child's death. Finally, several participants also experienced inappropriate or unsympathetic attitudes from the police officers attending their child's death. CONCLUSIONS: Findings from our study indicate that parents' experiences of police presence in the PICU as part of a coronial investigation may be negative, leaving lasting impressions on their experiences of their child's death. These findings provide areas for improvements in care delivery and the treatment of newly bereaved parents during the early phases of a coronial investigation. PMID- 29571597 TI - A cross-sectional study of predictors of pain control during the transition from the surgical intensive care unit to surgical ward. AB - BACKGROUND: The transition of patients from the intensive care unit (ICU) to the ward is a complicated process and patients may be at risk of increased levels of pain. OBJECTIVES: The primary objective was to identify predictors of pain during the transition from the surgical ICU to the surgical ward. The secondary objective was to describe the patient pain experience during this transition. METHODS: This was a cross-sectional study conducted at an academic medical centre in the United States. Patients who were discharged from the ICU were interviewed regarding their pain during transition from ICU to the ward using the Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R). The primary outcome measures were the total score of this validated instrument (0-180 points) and score of the pain severity and sleep interference subscale (0-50 points). Predictors of pain control during this 24-h transition period were identified using linear regression analysis. RESULTS: A total of 50 patients were included. After transition from the ICU, the median score on the APS-POQ-R was 45 (Q1 29 to Q3 74), and the median score on the pain severity and sleep interference subscale was 23 (Q1 15 to Q3 30). After adjusting for sex in a multivariate model, mean pain score in the preceding 24 h of ICU stay explained 31% of the variation in total APS-POQ-R score and 39% of variation in the pain severity and sleep interference subscale. Age, sex, race, type of surgery, number of surgeries, and opioid dose in the 24-h period before transfer were not significantly associated with either outcome measure. The worst pain experienced by patients during transfer was severe (i.e. score >=7 on 0 to 10 scale) in 90% (n = 45) of patients. For 70% (n = 35) of patients, severe pain persisted for more than 50% of the time during the transition period. CONCLUSION: Pain scores in the last 24 h of ICU stay is a predictor of total APS-POQ-R score and pain severity and sleep interference subscale score. PMID- 29571598 TI - Behavioral Profile of Children With Vocal Fold Nodules-A Case-control Study. AB - OBJECTIVES: The aim of this case-control study was to evaluate the overall behavior of children with vocal fold nodules (VNs). METHODS: The study group included children with VNs between 4 and 15 years old diagnosed using fiberoptic video laryngoscopy with stroboscopy in a tertiary university hospital. As a control group, children between 4 and 13 years old without VNs, routinely followed up in a primary care facility, were included in the study. Parents of the participants completed the parent-proxy strengths and difficulties questionnaire (SDQ), a brief behavioral screening questionnaire designed for children. The SDQ evaluates emotional, conduct, and peer problems, and also focuses on hyperactivity and prosocial behavior. Children are classified into "normal," "borderline," or "abnormal" according to the total SDQ score. RESULTS: Twenty-seven children (24 boys and 3 girls) with VNs and 41 controls (33 boys and 8 girls) were enrolled in the study. The two groups did not differ significantly in age or gender (P > 0.05). Statistical analysis revealed that 52% individuals of the VNs group presents borderline or abnormal overall behavioral, which is statistically different from the general population (P < 0.001). Total, hyperactivity, and prosocial SDQ subscales were statistically different between study groups (P < 0.05). CONCLUSIONS: Our findings suggest association between VNs and hyperactivity and also with poorer prosocial behaviors in children for the first time. We propose that every child with VNs must be evaluated from a behavioral point of view to detect and to treat potential underlying psychological conditions that may interfere with VNs treatment and prognosis. PMID- 29571599 TI - Similitude assessment method for comparing PMHS response data from impact loading across multiple test devices. AB - Biological tissue testing is inherently susceptible to the wide range of variability specimen to specimen. A primary resource for encapsulating this range of variability is the biofidelity response corridor or BRC. In the field of injury biomechanics, BRCs are often used for development and validation of both physical, such as anthropomorphic test devices, and computational models. For the purpose of generating corridors, post-mortem human surrogates were tested across a range of loading conditions relevant to under-body blast events. To sufficiently cover the wide range of input conditions, a relatively small number of tests were performed across a large spread of conditions. The high volume of required testing called for leveraging the capabilities of multiple impact test facilities, all with slight variations in test devices. A method for assessing similitude of responses between test devices was created as a metric for inclusion of a response in the resulting BRC. The goal of this method was to supply a statistically sound, objective method to assess the similitude of an individual response against a set of responses to ensure that the BRC created from the set was affected primarily by biological variability, not anomalies or differences stemming from test devices. PMID- 29571600 TI - Stability basin estimates fall risk from observed kinematics, demonstrated on the Sit-to-Stand task. AB - The ability to quantitatively measure stability is essential to ensuring the safety of locomoting systems. While the response to perturbation directly reflects the stability of a motion, this experimental method puts human subjects at risk. Unfortunately, existing indirect methods for estimating stability from unperturbed motion have been shown to have limited predictive power. This paper leverages recent advances in dynamical systems theory to accurately estimate the stability of human motion without requiring perturbation. This approach relies on kinematic observations of a nominal Sit-to-Stand motion to construct an individual-specific dynamic model, input bounds, and feedback control that are then used to compute the set of perturbations from which the model can recover. This set, referred to as the stability basin, was computed for 14 individuals, and was able to successfully differentiate between less and more stable Sit-to Stand strategies for each individual with greater accuracy than existing methods. PMID- 29571601 TI - High circulating CD4+CD25hiFOXP3+ T-cell sub-population early after lung transplantation is associated with development of bronchiolitis obliterans syndrome. AB - BACKGROUND: Chronic bronchiolitis obliterans syndrome (BOS) remains a major limitation for long-term survival after lung transplantation. The immune mechanisms involved and predictive biomarkers have yet to be identified. The purpose of this study was to determine whether peripheral blood T-lymphocyte profile could predict BOS in lung transplant recipients. METHODS: An in-depth profiling of CD4+ and CD8+ T cells was prospectively performed on blood cells from stable (STA) and BOS patients with a longitudinal follow-up. Samples were analyzed at 1 and 6 months after transplantation, at the time of BOS diagnosis, and at an intermediate time-point at 6 to 12 months before BOS diagnosis. RESULTS: Although no significant difference was found for T-cell compartments at BOS diagnosis or several months beforehand, we identified an increase in the CD4+CD25hiFoxP3+ T-cell sub-population in BOS patients at 1 and 6 months after transplantation (3.39 +/- 0.40% vs 1.67 +/- 0.22% in STA, p < 0.001). A CD4+CD25hiFoxP3+ T-cell threshold of 2.4% discriminated BOS and stable patients at 1 month post-transplantation. This was validated on a second set of patients at 6 months post-transplantation. Patients with a proportion of CD4+CD25hiFoxP3+ T cells up to 2.4% in the 6 months after transplantation had a 2-fold higher risk of developing BOS. CONCLUSIONS: This study is the first to report an increased proportion of circulating CD4+CD25hiFoxP3+ T cells early post-transplantation in lung recipients who proceed to develop BOS within 3 years, which supports its use as a BOS predictive biomarker.

PMID- 29571602 TI - Heart failure after the Norwood procedure: An analysis of the Single Ventricle Reconstruction Trial. AB - BACKGROUND: Heart failure results in significant morbidity and mortality in young children with hypoplastic left heart syndrome (HLHS) after the Norwood procedure. METHODS: We studied subjects enrolled in the prospective Single Ventricle Reconstruction (SVR) Trial who survived to hospital discharge after a Norwood operation and were followed up to age 6 years. The primary outcome was heart failure, defined as heart transplant listing after Norwood hospitalization, death attributable to heart failure, or symptomatic heart failure (New York Heart Association [NYHA] Class IV). Multivariate modeling was undertaken using Cox regression methodology to determine variables associated with heart failure. RESULTS: Of the 461 subjects discharged home following a Norwood procedure, 66 (14.3%) met the criteria for heart failure. Among these, 15 died from heart failure, 39 were listed for transplant (22 had a transplant, 12 died after listing, and 5 were alive and not yet transplanted), and 12 had NYHA Class IV heart failure but were never listed. The median age at heart failure identification was 1.28 (interquartile range 0.30 to 4.69) years. Factors associated with early heart failure included post-Norwood lower fractional area change, need for extracorporeal membrane oxygenation, non-Hispanic ethnicity, Norwood perfusion type, and total support time (p < 0.05). CONCLUSIONS: By 6 years of age, heart failure developed in nearly 15% of children after the Norwood procedure. Although transplant listing was common, many patients died from heart failure before receiving a transplant or without being listed. Shunt type did not impact the risk of developing heart failure.

The aims of the present study were to develop a predictive equation for RMR estimation in class III obese women using anthropometric indicators and to compare indirect calorimetry with other predictive equations. METHODS: This was a cross-sectional study on women with class III obesity (body mass index >40 kg/m2). Weight, height, fat-free mass, fat mass, and RMR of all individuals were measured. Multiple linear regression was used to determine the new RMR equation and the Bland-Altman plot was used to analyze the agreement between indirect calorimetry and the results of predictive equations. RESULTS: We evaluated 101 women with obesity class III and a mean age of 36.3 +/- 10 y. The anthropometric and body composition variables used in the new equation had a coefficient of determination of 0.80, and a significant influence on RMR (P = 0.01). Harris-Benedict and World Health Organization equations showed similar bias and limits (181.6, +2 SD = 765.5, -2 SD = -402.2; 156.4, +2 SD = 799.4, -2 SD = -486.6, respectively). The Mifflin-St Jeor and Owen equations showed large clinical bias (mean, 239.2 and 463.9, respectively), and a tendency to overestimate RMR. CONCLUSION: The prediction equations tested in the study had low accuracy in estimating RMR of women with class III obesity. However, our equation was developed specifically for this population, using variables known to influence their energy expenditure.

AB - OBJECTIVE: Successful weight loss and maintenance after Roux-en-Y gastric bypass (RYGB) may be related to eating behavior. The aim of this study was to assess the eating behavior domains that prevail in women during the RYGB postoperative period and their associations with surgery outcome. METHODS: This cross-sectional study investigated eating behavior in 95 women (47.3 +/- 9.8 y old) >= 2 y after Roux-en-Y gastric bypass. Patients were grouped according to surgery outcome: successful group (SG; n = 67), defined as having lost >= 50% of the preoperative excess weight loss (EWL), and an unsuccessful group (UG; n = 28). Mean postoperative time was 59.5 +/- 21.2 mo (55.7 +/- 19.9 in the SG and 68.6 +/- 21.9 in the UG). The short version of the Three-Factor Eating Questionnaire was used to assess cognitive restraint, emotional eating, and uncontrolled eating behaviors. Multivariate analysis was used to investigate associations between eating behavior scores and EWL. RESULTS: The highest score in both groups was for the cognitive restraint domain, followed by emotional and uncontrolled eating. Emotional eating was negatively associated with percentage of EWL (beta = -0.286; P = 0.033), regardless of age, educational attainment, and postoperative time. CONCLUSION: The cognitive restraint domain was the main type of eating behavior observed, and patients with higher emotional eating score were at a higher risk for having insufficient weight loss after RYGB. These results indicate the relevance of monitoring emotional components during the long-term nutritional follow-up of bariatric patients to achieve better surgery outcomes. PMID- 29571606 TI - Processed meat and selected hormone-related cancers. AB - OBJECTIVE: To assess and quantify the association between processed meat consumption and cancers of the breast, endometrium, ovary, and prostate. METHODS: Data were derived from an integrated network of hospital-based case-control studies conducted between 1982 and 2006 in various Italian areas. These studies included 5981 cases of cancer of the breast, 992 of the endometrium, 2002 of the ovary, 1582 of the prostate, and a total of 16 394 controls with data on processed meat. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional multiple logistic regression models, adjusted for major recognized confounders for each cancer site. RESULTS: The median consumption of processed meat in this population was 2 portions per wk in each cancer-specific cases, controls, and overall, corresponding to 100 g/wk. The OR for the highest (>=20 g/d) compared with lowest (<10 g/d) category of processed meat consumption was 1.16 (95% CI 1.06-1.28) for breast, 1.31 (95% CI 1.07-1.60) for endometrial, 1.49 (95% CI 1.30-1.71) for ovarian, and 0.89 (95% CI 0.74-1.07) for prostate cancer. CONCLUSION: In this case-control study, we found some excess risks of high processed meat consumption with female hormone-related cancers. Conversely, no association with prostate cancer was found in men. PMID- 29571607 TI - Vitamin D deficiency and high serum IL-6 concentration as risk factors for tubal factor infertility in Chinese women. AB - OBJECTIVES: The aim of this study was to investigate the relationship between 25 hydroxyvitamin-D [25(OH)D] and female infertility and to further explore the role of inflammatory cytokines. METHOD: We recruited 356 infertile women diagnosed with tubal factor infertility (TFI) or polycystic ovary syndrome (PCOS) or endometriosis, as well as 180 fertile women. Serum concentrations of 25(OH)D, interleukin (IL)-6, IL-1 beta, and interferon-alpha were measured. RESULTS: The 25(OH)D concentration in TFI women was the lowest (16.9 ng/mL) and was significantly different from that in the fertile women (19.4 ng/mL; P <0.05)]; whereas women with TFI had higher IL-6 concentrations. After adjusting for confounders, 25(OH)D deficiency presented a risk factor for TFI (odds ratio [OR], 4.2; 95% confidence interval [CI], 1.5-11.3). There was a dose-effect relation between IL-6 tertiles and TFI: the higher the IL-6, the higher the risk for TFI (middle versus low: OR, 3.7; 95% CI, 1.5-9.5; high versus low: OR, 13.2; 95% CI, 4.8-36.4). IL-6 showed a negative correlation with 25(OH)D (r = -0.19). Women with both high IL-6 and low 25(OH)D had the highest risk for TFI (OR, 10.6; 95% CI, 4.2-26.3). CONCLUSIONS: Both vitamin D deficiency and high serum IL-6 concentration are risk factors for TFI. Serum 25(OH)D concentration was significantly and negatively correlated with serum IL-6. There was an interaction between IL-6 and 25(OH)D for the risk for TFI-related infertility. We hypothesized that vitamin D might reduce the risk for TFI through suppressing the production of IL-6. PMID- 29571608 TI - Physicochemical stable standard all-in-one parenteral nutrition admixtures for infants and children in accordance with the ESPGHAN/ESPEN guidelines. AB - OBJECTIVE: Because there are almost no standard all-in-one parenteral nutrition admixtures available for infants and children, the aim was to develop standard two-compartment parenteral nutrition bags for different weight categories based on the ESPGHAN/ESPEN (European Society of Paediatric Gastroenterology, Hepatology and Nutrition/European Society for Clinical Nutrition and Metabolism) guidelines. The 1 g/kg/d lipid version for the 3 to 10 kg weight category (PED1) was assessed for short- and long-term physicochemical stability with the ability to add additional electrolytes (PED1+E). METHODS: The lipid compartment A and the all-in one admixture of A + B + vitamins + trace elements were assessed physically by visual inspection, Sudan red test, pH measurement, and lipid droplet size distribution. Chemical stability for compartment A was evaluated by quantitative analyses of non-esterified fatty acids and peroxide content. The glucose-amino acid-electrolyte compartment B was evaluated physically by visual inspection, measuring particle contamination and pH. Chemical stability was assessed by discoloration, quantitative analyses of glucose, and the amino acids L-cysteine, L-tyrosine, and L-tryptophan. RESULTS: No phase separation or coalescence occurred, and the mean droplet size diameter did not exceed 0.5 um. Peroxide content and non-esterified fatty acids concentration of compartment A remained well below the limit of acceptation. No precipitation was detected for compartment B; only a slight yellow discoloration was noted at 80 d. Concentrations of glucose, L-tyrosine, and L-tryptophan remained stable; only L cysteine decreased significantly from its initial concentration. CONCLUSION: The two-compartment PED1 and PED1+E admixtures are stable up to 80 d 2 degrees to 8 degrees C + 24 h room temperature (RT) with an additional 7 d 2 degrees to 8 degrees C + 48 h RT after mixing and addition of vitamins and trace elements. PMID- 29571609 TI - Assessment of parenteral nutrition prescription in Canadian acute care settings. AB - BACKGROUND: Parenteral nutrition (PN) prescription can be challenging in patients with complex conditions and has potential complications. OBJECTIVE: To assess PN prescription, monitoring, and PN-related complications in a Canadian acute care setting. METHODS: This was a prospective cohort study in which patients receiving PN were assessed by an auditor for nutritional status, PN-related prescription, monitoring, and complications. In addition, length of stay and mortality were recorded. RESULTS: 147 patients (mean +/- SD 56.1 +/- 16.4 y) with complex diseases (Charlson comorbidity index, median [p25-p75] 2 [1-4]) were enrolled. Before starting PN, 18.6%, 63.9%, and 17.5% of patients were classified as subjective global assessment A, B, and C, respectively. Body mass index remained unchanged during the period on PN. On average, 89% and 73% of patients received <90% of their energy and protein requirements, respectively, but 65% received oral or enteral nutrition at some point during PN. The average daily energy provided by PN increased and stabilized on day 10, reaching 87.2 +/- 20.1% of the requirements. Line sepsis (6.8% of patients) and hyperglycemia (6.9%) were the most common complications. The overall mortality was 15.6%. For those alive, length of stay was 30 (range: 4-268) d. PN was discontinued because of transitioning to an oral diet (56.6%), enteral nutrition (17.6%), home PN (14.7%), palliative care (5.1%), death (4.4%), or other (1.5%). CONCLUSION: Most patients were malnourished at the start of PN. Energy and protein provided from PN were less than requirements, and the goals were reached with delay. Mortality was high, possibly as a result of complex diseases. PMID- 29571610 TI - Remodeling of the abdominal epithelial monolayer during the larva-pupa-adult transformation of Manduca. AB - During metamorphosis of insect epithelial monolayers, cells die, divide, and rearrange. In Drosophila undifferentiated diploid cells destined to form the adult cuticle of each abdominal segment segregate early in development from the surrounding polyploid larval epithelial cells of that segment as eight groups of diploid histoblast cells. The larval polyploid cells are programmed to die and be replaced by divisions and rearrangements of histoblast cells. By contrast, abdominal epithelial cells of Manduca larvae form a monolayer of cells representing different ploidy levels with no definitive segregation of diploid cells destined to form adult structures. These epithelial cells of mixed ploidy levels produce a thick smooth larval cuticle with sparsely distributed sensory bristles. Adult descendants of this larval monolayer produce a thinner cuticle with densely packed scale cells. The transition between these differentiated states of Manduca involves divisions of cells, changes in ploidy levels, and sorting of certain polyploid cells into circular rosette patches to minimize contacts of these polyploid cells with surrounding cells of equal or smaller size. Cells within the rosettes and some surrounding cells are destined to die and be replaced by remaining epithelial cells of uniform size and ploidy at pupa adult apolysis. PMID- 29571611 TI - JAK/STAT signaling prevents excessive apoptosis to ensure maintenance of the interfollicular stalk critical for Drosophila oogenesis. AB - Apoptosis not only eliminates cells that are damaged or dangerous but also cells whose function during development in patterning or organogenesis is complete. The successful formation of germ cells is essential for the perpetuation of a species. The production of an oocyte often depends on signaling between germline and somatic cells, but also between specialized types of somatic cells. In Drosophila, each developing egg chamber is separated from the next by a single file of interfollicular somatic cells. Little is known about the function of the interfollicular stalk, although its presumed role in separating egg chambers is to ensure that patterning cues from one egg chamber do not impact or disrupt the development of adjacent egg chambers. We found that cells comprising the stalk undergo a progressive decrease in number during oogenesis through an apoptotic dependent loss. The extent of programmed cell death is restricted by JAK/STAT signaling in a cell-autonomous manner to ensure that the stalk is maintained. Both a failure to undergo the normal reduction in stalk cell number, or to prevent excessive stalk cell apoptosis results in a decrease in fecundity. Thus, activation of JAK/STAT signaling in the Drosophila interfollicular stalk emerges as a model to study the tight regulation of signaling-dependent apoptosis. PMID- 29571612 TI - Kir2.1 is important for efficient BMP signaling in mammalian face development. AB - Mutations that disrupt the inwardly rectifying potassium channel Kir2.1 lead to Andersen-Tawil syndrome that includes periodic paralysis, cardiac arrhythmia, cognitive deficits, craniofacial dysmorphologies and limb defects. The molecular mechanism that underlies the developmental consequences of inhibition of these channels has remained a mystery. We show that while loss of Kir2.1 function does not affect expression of several early facial patterning genes, the domain in which Pou3f3 is expressed in the maxillary arch is reduced. Pou3f3 is important for development of the jugal and squamosal bones. The reduced expression domain of Pou3f3 is consistent with the reduction in the size of the squamosal and jugal bones in Kcnj2KO/KO animals, however it does not account for the diverse craniofacial defects observed in Kcnj2KO/KO animals. We show that Kir2.1 function is required in the cranial neural crest for morphogenesis of several craniofacial structures including palate closure. We find that while the palatal shelves of Kir2.1-null embryos elevate properly, they are reduced in size due to decreased proliferation of the palatal mesenchyme. While we find no reduction in expression of BMP ligands, receptors, and associated Smads in this setting, loss of Kir2.1 reduces the efficacy of BMP signaling as shown by the reduction of phosphorylated Smad 1/5/8 and reduced expression of BMP targets Smad6 and Satb2. PMID- 29571614 TI - Coupling the roles of Hox genes to regulatory networks patterning cranial neural crest. AB - The neural crest is a transient population of cells that forms within the developing central nervous system and migrates away to generate a wide range of derivatives throughout the body during vertebrate embryogenesis. These cells are of evolutionary and clinical interest, constituting a key defining trait in the evolution of vertebrates and alterations in their development are implicated in a high proportion of birth defects and craniofacial abnormalities. In the hindbrain and the adjacent cranial neural crest cells (cNCCs), nested domains of Hox gene expression provide a combinatorial'Hox-code' for specifying regional properties in the developing head. Hox genes have been shown to play important roles at multiple stages in cNCC development, including specification, migration, and differentiation. However, relatively little is known about the underlying gene regulatory mechanisms involved, both upstream and downstream of Hox genes. Furthermore, it is still an open question as to how the genes of the neural crest GRN are linked to Hox-dependent pathways. In this review, we describe Hox gene expression, function and regulation in cNCCs with a view to integrating these genes within the emerging gene regulatory network for cNCC development. We highlight early roles for Hox1 genes in cNCC specification, proposing that this may be achieved, in part, by regulation of the balance between pluripotency and differentiation in precursor cells within the neuro-epithelium. We then describe what is known about the regulation of Hox gene expression in cNCCs and discuss this from the perspective of early vertebrate evolution. PMID- 29571616 TI - Laparoscopy-assisted versus open and pure laparoscopic approach for liver resection and living donor hepatectomy: a systematic review and meta-analysis. AB - BACKGROUND: Laparoscopy-assisted (hybrid) liver surgery is considered a minimally invasive technique, however there are doubts regarding loss of the benefits of laparoscopy due to the use of an auxiliary incision. The aim of this study was to compare perioperative results of hybrid vs. open and hybrid vs. pure laparoscopic approach to liver resection for focal lesions and living donation. METHODS: A systematic review was performed in Medline, EMBASE, Cochrane Library Central and LILACS databases. Perioperative outcomes were analyzed. RESULTS: 21 studies were included. Hybrid vs. open: operative time was lower in open group (mean difference [MD] = 34 min; 95%CI: 22-47; P < 0.001; N = 669). Hybrid technique was associated with a reduction in operative blood loss [MD = -43 ml; 95%CI: -74-( 13); P = 0.005, N = 1738]; shorter hospital stay [MD = -1.9 days; 95%CI: -3.2-( 0.5); P = 0.008; N = 833] and lower morbidity [risk difference (RD) = -0.05; 95%CI: -0.10-(-0.01); P = 0.010; N = 1359]. Hybrid vs. pure laparoscopic: There was no difference regarding blood loss, transfusion rate, hospital stay and morbimortality. DISCUSSION: Hybrid technique had perioperative outcomes that were more in keeping with pure laparoscopic outcomes than open surgery. Hybrid liver surgery should be considered a minimally invasive approach. PMID- 29571613 TI - Hypomorphic Smo mutant with inefficient ciliary enrichment disrupts the highest level of vertebrate Hedgehog response. AB - Smoothened (Smo) is the essential transducer of Sonic hedgehog (Shh) signaling, which regulates cell fate and proliferation during embryogenesis. We identified a novel mouse mutant, cabbie (cbb), and found that its cause is a missense mutation in Smo. We showed the Smocbb mutation is insensitive to the Shh agonist SAG, perhaps due to the disruption of SAG binding. We characterized Smocbb for defects in craniofacial and skeletal development, as well as neural tube patterning, and revealed Smocbb affected processes that require the highest levels of Shh activity. Smo is normally enriched in cilia upon Shh stimulation; however, we detected inefficient enrichment of Smo in Smocbb mutants whether we stimulated with Shh or SAG. Taken together, our data suggest that the highest levels of vertebrate Hedgehog signaling activity require efficient Smo ciliary enrichment. PMID- 29571615 TI - Variation in hospital mortality after pancreatoduodenectomy is related to failure to rescue rather than major complications: a nationwide audit. AB - BACKGROUND: In the mandatory nationwide Dutch Pancreatic Cancer Audit, rates of major complications and Failure to Rescue (FTR) after pancreatoduodenectomy between low- and high-mortality hospitals are compared, and independent predictors for FTR investigated. METHODS: Patients undergoing pancreatoduodenectomy in 2014 and 2015 in The Netherlands were included. Hospitals were divided into quartiles based on mortality rates. The rate of major complications (Clavien-Dindo >=3) and death after a major complication (FTR) were compared between these quartiles. Independent predictors for FTR were identified by multivariable logistic regression analysis. RESULTS: Out of 1.342 patients, 391 (29%) developed a major complication and in-hospital mortality was 4.2%. FTR occurred in 56 (14.3%) patients. Mortality was 0.9% in the first hospital quartile (4 hospitals, 327 patients) and 8.1% in the fourth quartile (5 hospitals, 310 patients). The rate of major complications increased by 40% (25.7% vs 35.2%) between the first and fourth hospital quartile, whereas the FTR rate increased by 560% (3.6% vs 22.9%). Independent predictors of FTR were male sex (OR = 2.1, 95%CI 1.2-3.9), age >75 years (OR = 4.3, 1.8-10.2), BMI >=30 (OR = 2.9, 1.3-6.6), histopathological diagnosis of periampullary cancer (OR = 2.0, 1.1 3.7), and hospital volume <30 (OR = 3.9, 1.6-9.6). CONCLUSIONS: Variations in mortality between hospitals after pancreatoduodenectomy were explained mainly by differences in FTR, rather than the incidence of major complications. PMID- 29571617 TI - Alcohol injection into the portal vein prior to ligation increases liver regeneration rate. AB - BACKGROUND: Failure of portal vein ligation (PVL) to induce hypertrophy is not uncommon. The aim of the study was to evaluate the impact of intraportal alcohol injection prior to ligation on liver regeneration. METHOD: Forty-two patients with colorectal liver metastases who underwent PVL between 01/2004 and 06/2014 were analyzed. Beginning in 09/2011, alcohol was injected prior to PVL. Patients treated with PVL alone (Alc- group) were compared with those treated with alcohol injection plus PVL (Alc+ group). Liver regeneration was assessed by volumetric increase (VI). RESULTS: Alc+ (23 patients) and Alc- (19 patients) groups were similar in terms of age, sex and pre-PVL FLRV. Alc- group had a higher risk of recanalization (12 vs. 1, p < 0.001) and cavernous transformation (7 vs. 2, p = 0.055) of the occluded portal vein. Post-PVL FLRV (43.3 +/- 14.3% vs. 34.6 +/- 6.4%, p = 0.013) and VI (0.44 +/- 0.24 vs. 0.28 +/- 0.20, p = 0.029) were higher in Alc+ group. On multivariate analysis male sex (B = -0.149) and alcohol injection (B = 0.143) significantly predicted VI. CONCLUSIONS: Alcohol injection prior to PVL may increase the regeneration of the FLRV by reducing the recanalization of the occluded portal vein. PMID- 29571618 TI - Insight on ALPPS - Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy - mechanisms: activation of mTOR pathway. AB - BACKGROUND: ALPPS procedure has been introduced to increase the volume of future liver remnant. The mechanisms underlying the accelerated regeneration observed with ALPPS are unknown. It was hypothesized that AMPK/mTOR is activated as an integrating pathway for metabolic signals leading to proliferation and cell growth. Our aim was to analyze increase in liver volume, proliferation parameters and expression of AMPK/mTOR pathway-related molecules in patients undergoing ALPPS. METHODS: A single center prospective study of patients undergoing ALPPS was performed from 2013 to 2015. Liver and serum samples, clinical laboratory results and CT-scan data were obtained. ELISA, Ki-67 immunostaining and qRT-PCR were performed in deportalized and remnant liver tissue in both stages of the procedure. RESULTS: 11 patients were enrolled. Remnant liver volume increased 112 +/- 63% (p < 0.05) in 9.1 +/- 1.6 days. Proliferation-related cytokines IL-6, TNF alpha, HGF and EGF significantly increased, while higher Ki-67 immunostaining and cyclin D expression were observed in remnant livers after ALPPS. mTOR, S6K1, 4E BP1, TSC1 and TSC2 expression were significantly increased in remnant livers at second stage, while AMPK and Akt increased only in deportalized liver samples. CONCLUSION: Rapid liver regeneration with ALPPS might be associated with hepatocyte proliferation induced by mTOR pathway activation. PMID- 29571619 TI - Predictive factors of recurrent endovascular intervention for cephalic arch stenosis after percutaneous transluminal angioplasty. AB - OBJECTIVE: Cephalic arch stenosis (CAS) is an important and recurring problem arising in hemodialysis patients because of the requirement for repeated interventions to maintain patency. The aim of this study was to determine predictive factors for recurrence of CAS after successful angioplasty. METHODS: A retrospective, case-control study was conducted at two ambulatory vascular access (VA) centers. All patients with a dysfunctional VA referred for an angiographic procedure and with a documented CAS as evidenced during the endovascular intervention (EI) between January 1, 2013, and December 31, 2015, were enrolled; 15 patients in whom an efficacious intervention was not possible were excluded. The study thus concerned 375 EIs using percutaneous transluminal angioplasty without stent placement on 241 VAs for CAS (9% of all procedures performed) during a 3-year period. Patients were compared regarding the absence (group 1; n = 181) or presence (group 2; n = 60) of recurrent CAS. We defined recurrence as that which occurred within 180 days of the previous successful EI for CAS. Any CAS diagnosed and treated >180 days after a previous one was considered a novel CAS and not a recurrence. Multivariate analysis was performed to determine variables independently associated with recurrence of CAS. Kaplan-Meier analysis was performed for determination of primary and assisted primary patency in this population. RESULTS: The recurrence rate of CAS was high (25%). Patients in both groups had similar demographic characteristics, time on hemodialysis, and mean dialysis dose and access flow rate at referral (P > .05). Multivariate analysis provided a significant discriminatory influence pertaining to diabetes (hazard ratio [HR], 2.054; 95% confidence interval [CI], 1.22-3.46; P = .007), residual stenosis even though it was <30% (HR, 1.86; 95% CI, 1.005-3.439; P = .048), and the finding of an isolated CAS lesion (HR, 0.445; 95% CI, 0.219-0.905; P = .025) in comparing group 1 and group 2. All other variables lost statistical significance on multivariate analysis. Primary patency at 6 months was 72%, increasing to an assisted primary patency of 89% at 6 months. The median durations of primary patency and assisted primary patency were 9.5 months and 15.6 months, respectively. CONCLUSIONS: Multivariate analysis showed that diabetes and residual stenosis (albeit <30%) were predictive of recurrence, whereas the finding of an isolated CAS lesion as opposed to stenoses in multiple locations was shown to be negatively associated with recurrent CAS, appearing to be "protective". PMID- 29571620 TI - Regional variation in patient outcomes in carotid artery disease treatment in the Vascular Quality Initiative. AB - OBJECTIVE: Quality metrics were developed to improve outcomes after carotid artery revascularization; however, few studies have evaluated regional differences in perioperative outcomes. This study aimed to evaluate regional variation in mortality and perioperative outcomes after carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: We identified all patients who underwent CEA or CAS from 2009 to 2016 in the Vascular Quality Initiative. Patients were analyzed on the basis of their symptom status. We assessed variation in perioperative outcomes using chi2 analysis, Fisher exact test, and t test, where appropriate. RESULTS: A total of 78,467 carotid interventions were identified; 85% were CEAs, with 69% of those asymptomatic. Within CAS, 39% were asymptomatic. Perioperative stroke/death varied across regions within both CAS groups (asymptomatic, 0%-5.8% [P = .03]; symptomatic, 2.4%-8.1% [P = .1]), and several regions did not meet the American Heart Association (AHA) guidelines of 3% for asymptomatic patients and 6% for symptomatic patients, which persisted after risk adjustment. For CEA, the stroke/death rates fell within the standards set by the AHA guidelines in all regions for both the unadjusted and risk adjusted models; however, there was significant regional variation in the cohorts (asymptomatic, 0.9%-3.1% [P < .01]; symptomatic, 1.3%-4.9% [P < .01]). Variation in 30-day mortality was significant in symptomatic patients (asymptomatic: CEA, 0%-1.3% [P = .2], CAS, 0%-2.4% [P = .2]; symptomatic: CEA, 0%-1.8% [P < .01], CAS, 0%-4.6% [P = .01]). Rates of in-hospital stroke, postoperative myocardial infarction, prolonged length of stay (>2 days), and use of intravenous blood pressure medications all varied significantly across the regions. After CEA, there was significant variation in the rates of cranial nerve injuries (asymptomatic, 0.9%-4.9% [P < .01]; symptomatic, 1.5%-7.7% [P < .01]), return to the operating room (asymptomatic, 0.9%-3.4% [P < .01]; symptomatic, 0.6%-3.4% [P = .02]), and discharge on antiplatelet and statin (asymptomatic, 75%-87% [P < .01]; symptomatic, 78%-91% [P < .01]). After CAS, significant variation was found in the rates of access site complications (asymptomatic, 2.3%-18.2% [P < .01]; symptomatic, 1.4%-16.9% [P < .01]) and discharge on dual antiplatelet therapy (asymptomatic, 79%-94% [P < .01]; symptomatic, 83%-93% [P < .01]). CONCLUSIONS: Unwarranted regional variation exists in outcomes after carotid artery revascularization across the regions of the VQI. Significant variation was seen in a number of outcomes for which quality metrics currently exist, such as length of stay and discharge medications. In addition, after CAS, several regions failed to meet the AHA guidelines for stroke and death. Given these results, quality improvement projects should be targeted to improve adherence to current guidelines to promote best practices. PMID- 29571621 TI - Comparing the efficacy of shunting approaches and cerebral monitoring during carotid endarterectomy using a national database. AB - OBJECTIVE: Carotid endarterectomy practice patterns, including the use of shunts and cerebral monitoring techniques, are typically surgeon-dependent and differ greatly on a national level. Prior literature evaluating these techniques is often underpowered for detecting variations in low-frequency outcomes. The purpose of this study was to evaluate current carotid endarterectomy practice patterns and to allow comparison across surgical approaches using a large national database. METHODS: We divided carotid cases entered into the Vascular Quality Initiative database between October 2012 and April 2015 into routine shunting, selective shunting, and never shunting cohorts, excluding endarterectomies performed with concomitant procedures and those with incomplete information on the use of a shunt. The selective group was subdivided into cases with awake, electroencephalography, and stump pressure monitoring. We evaluated differences in practice patterns and compared rates of stroke, death, return to the operating room, reperfusion injury, and re-exploration after closure across these groups. Multivariate logistic regression models adjusting for risk factors were used to identify predictors of each outcome. RESULTS: Between October 2012 and April 2015, there were a total of 28,457 endarterectomies included in our analysis, of which 14,128 involved routine shunting, 1740 involved never shunting, and 12,489 involved selective shunting. Of the selective cases, 6144 involved electroencephalography monitoring, 2310 involved stump pressure monitoring, and 2052 involved awake monitoring. Unadjusted rates of in-hospital death and stroke were 0.30% (95% confidence interval [CI], 0.21-0.39) and 0.78% (95% CI, 0.64-0.93) for routine shunting and 0.22% (95% CI, 0.14-0.31) and 0.91% (95% CI, 0.75-1.08) for selective shunting, respectively. The unadjusted rate of in-hospital death was lower in the awake monitoring group than in the routine shunting group (0.05% vs 0.30%; P = .037). After adjustment for patient risk factors, the multivariate models showed no difference in rates of any primary outcomes among the groups, although there was a shorter postoperative length of stay for the awake monitoring group compared with the routine shunting group (1.55 days vs 2.00 days, respectively; P < .01). CONCLUSIONS: Analysis of the Vascular Quality Initiative registry shows equivalent unadjusted rates of in hospital death and stroke across different approaches to shunting and cerebral monitoring with the exception of the awake monitoring group, which has lower unadjusted mortality compared with the routine shunting group. In the risk adjusted analysis, however, there are no differences across any of the groups. Given the clinical equivalence of approaches to shunting and cerebral monitoring, further work should evaluate the relative cost of these techniques. PMID- 29571622 TI - Comparison between activated clotting time and anti-activated factor X activity for the monitoring of unfractionated heparin therapy in patients with aortic aneurysm undergoing an endovascular procedure. AB - OBJECTIVE: Current guidelines recommend administration of unfractionated heparin (UFH) and measurement of activated clotting time (ACT) during endovascular procedures. The aim of this study was to compare ACT and anti-activated factor X (anti-Xa) measurements for monitoring of UFH therapy during an aortic endograft procedure and to assess the association of peak ACT and peak anti-Xa activity with periprocedural bleeding. METHODS: We retrospectively studied 104 patients with aortic aneurysm undergoing endovascular procedures with repeated coagulation measurements. After a UFH bolus, further UFH doses were given according to ACT (target range, >=250 seconds) in clinical routine, and in parallel to each ACT (Hemochron; Accriva Diagnostics, Newport Beach, Calif) measurement, we determined anti-Xa activity (HemosIL Liquid anti-Xa; Instrumentation Laboratory, Bedford, Mass). UFH redosing was solely based on the ACT measurements. We defined periprocedural bleeding as a drop in hemoglobin level >=3 g/dL or red blood cell transfusion within 24 hours. RESULTS: After the initial UFH bolus (median, 67 IU/kg body weight), ACT and anti-Xa measurements showed a weak correlation (rs, 0.46; P < .001). Median ACT was 233 seconds (range, 127-374 seconds; interquartile range [IQR], 204-257 seconds); median anti-Xa activity was 1.0 IU/mL (range, 0.5-2.0 IU/mL; IQR, 0.9-1.2 IU/mL). Only 31% of the patients had an ACT value >=250 seconds, whereas all patients had an anti-Xa activity >=0.5 IU/mL. Accordingly, ACT triggered redosing of UFH frequently. Consequently, we saw a median total UFH use of 90 IU/kg during the procedure, a median peak ACT of 255 seconds (IQR, 234-273 seconds), and a median peak anti-Xa activity of 1.2 IU/mL (IQR, 1.0-1.4 IU/mL). Periprocedural bleeding occurred in 40 (38%) patients. Peak ACT >=250 seconds was not associated with bleeding (odds ratio, 1.05; 95% confidence interval, 0.41-2.70; P = .952), whereas peak anti-Xa activity >=1.2 IU/mL was independently associated with bleeding (odds ratio, 4.95; 95% confidence interval, 1.82-13.48; P = .002). Moreover, no periprocedural thromboembolic event occurred. CONCLUSIONS: In this retrospective study of patients with aortic aneurysm undergoing an endovascular procedure, ACT and anti Xa measurements showed poor correlation; only increased peak anti-Xa activity was independently associated with periprocedural bleeding, not increased ACT. Our findings also suggest that monitoring of UFH therapy with anti-Xa during aortic endograft procedures may reduce total UFH use. We further speculate that this approach could reduce periprocedural bleeding. PMID- 29571623 TI - Real-world evidence of superiority of endovascular repair in treating ruptured abdominal aortic aneurysm. AB - OBJECTIVE: The majority of previous studies, including randomized controlled trials, have failed to provide sufficient evidence of superiority of endovascular aneurysm repair (EVAR) over open aortic repair (OAR) of ruptured abdominal aortic aneurysm (rAAA) while comparing mortality and complications. This is in part due to small study size, patient selection bias, scarce adjustment for essential variables, single insurance type, or selection of only older patients. This study aimed to provide real-world, contemporary, comprehensive, and robust evidence on mortality of EVAR vs OAR of rAAA. METHODS: A retrospective observational cohort study was performed of rAAA patients registered in the Premier Healthcare Database between July 2009 and March 2015. A multivariate logistic regression model was operated to estimate the association between procedure types (OAR vs EVAR) and in-hospital mortality. The final model was adjusted for demographics (age, sex, race, marital status, and geographic region), hospital characteristics (urban or rural, teaching or not), and potential confounders (hypertension, diabetes, hypercholesterolemia, obesity, ischemic heart disease, chronic kidney disease, symptoms of critical limb ischemia, chronic obstructive pulmonary disease, smoking, and alcoholism). Furthermore, coarsened exact matching was applied to substantiate the result in the matched cohort. RESULTS: There were a total of 3164 patients with rAAA (1550 [49.0%] OAR and 1614 [51.0%] EVAR). Mortality was 23.79% in the EVAR group compared with 36.26% in the OAR group (P < .001). The adjusted odds ratios of mortality (1.91; 95% confidence interval [CI], 1.62-2.25; P < .001), cardiac complication (1.54; 95% CI, 1.22-1.96; P < .001), pulmonary failure (1.90; 95% CI, 1.60-2.24; P < .001), renal failure (1.90; 95% CI, 1.61-2.23; P < .001), and bowel ischemia (2.40; 95% CI, 1.70-3.35; P < .001) were significantly higher after OAR compared with EVAR. We further applied coarsened exact matching, which followed the same pattern of mortality (odds ratio, 1.68; 95% CI 1.41-1.99; P < .001) and all major complications. CONCLUSIONS: Although the choice of repair of rAAA is highly dependent on the experience of the operating team and the anatomic suitability of the patient, this contemporary analysis of a large cohort of rAAA showed significantly higher adjusted risk of mortality in OAR compared with EVAR and substantially higher complications. PMID- 29571624 TI - Tissue factor levels and the fibrinolytic system in thin and thick intraluminal thrombus and underlying walls of abdominal aortic aneurysms. AB - BACKGROUND: The hemostatic system cooperates with proteolytic degradation in processes allowing abdominal aortic aneurysm (AAA) formation. In previous studies, it has been suggested that aneurysm rupture depends on intraluminal thrombus (ILT) thickness, which varies across each individual aneurysm. We hypothesized that hemostatic components differentially accumulate in AAA tissue in relation to ILT thickness. Thick (A1) and thin (B1) segments of ILTs and aneurysm wall sections A (adjacent to A1) and B (adjacent to B1) from one aneurysm sac were taken from 35 patients undergoing elective repair. METHODS: Factor levels were measured using enzyme-linked immunosorbent assay of protein extract. RESULTS: Tissue factor (TF) activities were significantly higher in thinner segments of AAA (B1 vs A1, P = .003; B vs A, P < .001; B vs A1, P < .001; B vs B1, P = .001). Significantly higher tissue plasminogen activator was found in thick thrombus-covered wall segments (A) than in B, A1, and B1 (P = .015, P < .001, and P < .001, respectively). Plasminogen concentrations were highest in ILT. Concentrations of alpha2-antiplasmin in thin ILT adjacent walls (B) were higher compared with wall (A) adjacent to thick ILT (P = .021) and thick ILT (A1; P < .001). Significant correlations between levels of different factors were mostly found in thick ILT (A1). However, no correlations were found at B sites, except for a correlation between plasmin and TF activities (r = 0.55; P = .004). CONCLUSIONS: These results suggest that higher TF activities are present in thinner AAA regions. These parameters and local fibrinolysis may be part of the processes leading to destruction of the aneurysm wall. PMID- 29571625 TI - Preoperative mapping of the aortoiliac territory with duplex ultrasound in patients with peripheral arterial occlusive disease. AB - OBJECTIVE: Duplex ultrasound (DUS) arterial mapping of the aortoiliac area is limited by obesity, abdominal gas, and the need to use a low-frequency probe (and therefore poorer resolution) in the examination. The aim of this study was to analyze the degree of agreement between DUS mapping of the aortoiliac area and angiography or contrast-enhanced computed tomography angiography (CTA). METHODS: This was a retrospective observational study. Between November 2006 and June 2015, there were 173 patients with a surgical indication for aortoiliac occlusive disease included, with preoperative aortoiliac DUS mapping and subsequent CTA or intraoperative angiography. Sensitivity, specificity, positive predictive value, and negative predictive value of DUS as an arterial mapping test were analyzed, as was the degree of agreement with angiography/CTA and agreement between the surgical indication based on DUS and the final surgical technique performed. RESULTS: Of 173 DUS mapping tests, 155 were evaluated (89.6%); the remaining 18 were not able to be evaluated because of the patient's obesity or bowel gas. Overall accuracy of DUS for predicting significant artery lesions was as follows: 92% sensitivity (95% confidence interval [CI], 88%-95%), 96% specificity (95% CI, 95%-97%), 89% positive predictive value (95% CI, 86%-93%), and 97% negative predictive value (95% CI, 96%-98%). Agreement with angiography/CTA had a kappa index of 0.81 (95% CI, 0.77-0.84), which reflects a good degree of agreement. Surgical indications based on DUS mapping were correct in 89% of cases (138/155). CONCLUSIONS: DUS mapping of the aortoiliac territory could be used as a single preoperative imaging test in aortoiliac occlusive disease in patients whose DUS examination is able to be evaluated. PMID- 29571626 TI - A systematic review and meta-analysis of endovascular versus open surgical revascularization for chronic mesenteric ischemia. AB - BACKGROUND: Despite the enthusiasm for endovascular revascularization for chronic mesenteric ischemia (CMI), it is not clear if early benefits offset long-term patency rates. This systematic review aimed to provide an up-to-date comprehensive evidence synthesis evaluating the two approaches. METHODS: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through July 15, 2016, for studies that compared the endovascular with the open surgical approach for revascularization in CMI patients. We conducted a random-effects meta-analysis to pool outcomes of interest across studies. RESULTS: We included 100 observational studies (22 comparative, 78 noncomparative; 18,726 patients; mean age, 69 years). Open surgery was associated with a statistically significant increase in the risk of in-hospital complications (relative risk [RR], 2.2; 95% confidence interval [CI], 1.8-2.6) and a nonsignificant increase in mortality at 30 days (RR, 1.57; 95% CI, 0.84-2.93). Open surgery was associated with lower risk of 3-year recurrence rates (RR, 0.47; 95% CI, 0.34-0.66) and a similar 3-year survival. Data from noncomparative studies provided similar inferences. The quality of evidence was low. CONCLUSIONS: Observational evidence suggests that the endovascular approach for revascularization in patients with CMI may offer better early outcomes than open surgery, although this effect may not be durable. Long term mortality appears to be similar. PMID- 29571627 TI - Long-term decline in renal function is more significant after endovascular repair of infrarenal abdominal aortic aneurysms. AB - OBJECTIVE: It is not clear whether endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) results in an increase in renal insufficiency during the long term compared with open repair (OR). We reviewed our experience with AAA repair to determine whether there was a significant difference in postoperative and long-term renal outcomes between OR and EVAR. METHODS: A retrospective cohort study was conducted of all patients who underwent AAA repair between January 1993 and July 2013 at a tertiary referral hospital. Demographics, comorbidities, preoperative and postoperative laboratory values, morbidity, and mortality were collected. Patients with ruptured AAAs, preoperative hemodialysis, juxtarenal or suprarenal aneurysm origin, and no follow-up laboratory values were excluded. Preoperative, postoperative, 6-month, and yearly serum creatinine values were collected. Glomerular filtration rate (GFR) was calculated on the basis of the Chronic Kidney Disease Epidemiology Collaboration equation. Acute kidney injury (AKI) was classified using the Kidney Disease: Improving Global Outcomes guidelines. Change in GFR was defined as preoperative GFR minus the GFR at each follow-up interval. Comparison was made between EVAR and OR groups using multivariate logistics for categorical data and linear regression for continuous variables. RESULTS: During the study period, 763 infrarenal AAA repairs were performed at our institution; 675 repairs fit the inclusion criteria (317 ORs and 358 EVARs). Mean age was 73.9 years. Seventy-nine percent were male, 78% were hypertensive, 18% were diabetic, and 31% had preoperative renal dysfunction defined as GFR below 60 mL/min. Using a multivariate logistic model to control for all variables, OR was found to have a 1.6 times greater chance for development of immediate postoperative AKI compared with EVAR (P = .038). Hypertension and aneurysm size were independent risk factors for development of AKI (P = .012 and .022, respectively). Using a linear regression model to look at GFR decline during several years, there was a greater decline in GFR in the EVAR group. This became significant starting at postoperative year 4. AKI and preoperative renal dysfunction were independent risk factors for long-term decline in renal function. CONCLUSIONS: Although AKI is less likely to occur after EVAR, patients undergoing EVAR experience a significant but delayed decline in GFR over time compared with OR. This became apparent after postoperative year 4. Studies comparing EVAR and OR may need longer follow-up to detect clinically significant differences in renal function. PMID- 29571628 TI - Differences in alpha-Crystallin isomerization reveal the activity of protein isoaspartyl methyltransferase (PIMT) in the nucleus and cortex of human lenses. AB - Although it is well-known that protein turnover essentially stops in mature lens fiber cells, mapping out the ensuing protein degradation and its effects on lens function over time remains challenging. In particular, isomerization is a common, spontaneous post-translational modification that occurs over long timescales and generates products invisible to most analytical methods. Nevertheless, isomerization can significantly impact protein structure, function, and solubility, which are all necessary to maintain clarity and proper refractive index within the lens. Herein, we examine the degree of isomerization occurring in crystallin proteins in the human eye lens as a function of both age and location within the lens. A novel mass spectrometric technique leveraging radical chemistry enables detailed characterization of proteins extracted from the cortex and nucleus of the lens. It is observed that the degree of isomerization increases significantly between the cortex and nucleus and between water-soluble and water-insoluble fractions. Interestingly, the abundance of L-isoAsp is low in the water-soluble cortex despite being the dominant product generated by isomerization of Asp in vitro, suggesting that Protein L-isoaspartyl methyltransferase (PIMT) is active in the cortex and suppresses the accumulation of L-isoAsp. The abundance of L-isoAsp increases dramatically in the nucleus, revealing that PIMT activity decreases over time in the center of the lens. In addition, the growth of L-isoAsp in the nuclear fraction suggests protein isomerization continues within the nucleus, despite the fact that most of the protein within the nucleus has become insoluble. Additionally, it is demonstrated that sequential Asp residues lead to isomerization hotspots in human crystallin proteins and that the isomerization profiles for alphaA and alphaB crystallin are notably different. Although alphaA is more prone to isomerization, alphaB loses solubility more rapidly upon modification. These differences are likely related to the distribution of Asp residues within alphaA and alphaB, which are in turn connected to refractive index. The high Asp content of alphaA is a hazard in terms of isomerization and aging, but it serves to enhance the refractive index of alphaA relative to alphaB, and may explain why alphaA is only found in the eye. PMID- 29571629 TI - Partial retinal photoreceptor loss in a transgenic mouse model associated with reduced levels of interphotoreceptor retinol binding protein (IRBP, RBP3). AB - Organ-specific transgenic membrane expression of hen egg lysozyme (HEL) as a "neo self antigen" has been used in several models to study immunological tolerance. In this study we report the changes which occur in the B10.BR mouse retina when membrane-bound HEL is expressed in photoreceptors under the control of the promoter for interphotoreceptor retinoid binding protein (IRBP, RBP3). On direct clinical examination of the single transgenic (sTg-IRBP:HEL) mouse fundus, a low level increase in retinal degeneration compared to non-transgenic controls was observed, presenting as drusenoid deposits and occasional small patches of atrophy. On histological examination, there was an overall shortening of outer segments and loss of photoreceptor nuclei in sTg-IRBP:HEL mice, which was more pronounced in the retinal periphery, particularly inferiorly. The fundoscopically observed lesions did not correlate with the photoreceptor shortening/loss but appeared to be located at the level of the retinal pigment epithelium/choriocapillaris layer and were an exaggeration in size and number of similar age-related changes found in wild type (WT) mice. In addition, neither the atrophic lesions nor the photoreceptor shortening were associated with common retinal degeneration genes, nor were they caused by exposure to light damage since mice housed at both high and low ambient light levels had similar degrees of retinal degeneration. Instead, sTg-IRBP:HEL mice expressed reduced levels of soluble retinal IRBP compared to WT mice which were present from postnatal day16 (P16) and preceded development of photoreceptor shortening (onset P21). We propose that insertion of the HEL transgene in the photoreceptor membrane disrupted normal photoreceptor function and led to reduced levels of soluble IRBP and retinal thinning. A similar phenotype has been observed in IRBP deficient mice. Despite the retinal thinning, the amount of HEL expressed in the retina was sufficient to act as an autoantigenic target when the mice were crossed to the HEL T cell receptor Tg mouse, since double transgenic (dTg-IRBP:HEL) mice spontaneously developed a severe uveoretinitis with onset at weaning. We suggest that, although membrane expression of foreign transgene products is likely to modify the structure and function of tissues and cells, the technology provides useful models to investigate mechanisms of antigen-specific immunological tolerance. PMID- 29571630 TI - Short- and long-term freezing effects in a coastal (Lobaria virens) versus a widespread lichen (L. pulmonaria). AB - Lichens are considered freezing tolerant, although few species have been tested. Growth, a robust measure of fitness integrating processes in all partners of a lichen thallus, has not yet been used as a viability measure after freezing. We compared relative growth rates (RGR) after freezing with short-term viability measures of photo- and mycobiont functions in the coastal Lobaria virens and the widespread L. pulmonaria to test the hypothesis that low temperature shapes the coastal distribution of L. virens. Hydrated thalli from sympatric populations were subjected to freezing at -10, -20 and -40 degrees C for 5 h. The rate of cooling and subsequent warming was 5 degrees C h-1. Short-term viability measures of photobiont (maximal photosystem II efficiency, effective PSII yield) and mycobiont viability (conductivity index), as well as subsequent RGR, were assessed. The exotherms showed that L. virens froze at -3 degrees C; L. pulmonaria, at -4 degrees C. Freezing significantly impaired short-term viability measures of both photo- and mycobiont, particularly in the coastal species. Lobaria pulmonaria grew 2.1 times faster than L. virens, but the short term damage after one freezing event did not affect the long-term RGR in any species. Thereby, short-term responses were impaired by freezing, long-term responses were not. While the lacking RGR-responses to freezing suggest that freezing tolerance does not shape the coastal distribution of L. virens, the significant reported adverse short-term effects in L. virens may be aggravated by repeated freezing-thawing cycles in cold winters. In such a perspective, repeated freezing may eventually lead to reduced long-term fitness in L. virens.

PMID- 29571632 TI - Sperm kinematics and subpopulational responses during the cryopreservation process in caprine ejaculates. AB - Sperm cryopreservation in goats has been a challenge for many years due to the detrimental effects of seminal plasma enzymes produced by the bulbo-urethral glands which catalyse the hydrolysis of lecithins in egg yolk to fatty acids and lysolecithins which are deleterious to spermatozoa. This fact implies to carry out additional processing steps during sperm cryopreservation for seminal plasma removal triggering different sperm responses which may affect sperm functionality. The objective of the present study was to determine specific sperm subpopulation responses in different handling steps during the cryopreservation process by using functional sperm kinematic descriptors in caprine ejaculates. Buck ejaculates (n = 40) were analysed for sperm concentration, viability, morphology and acrosome integrity. Moreover, sperm motility was assessed using a computer-assisted sperm analysis (CASA) system after five different handling steps (fresh sperm, 1st washing, 2nd washing, cooling and frozen-thawed sperm) during a standard cryopreservation protocol for goat semen. The results were analysed using Principal Component Analysis (PCA) and multivariate clustering procedures to establish the relationship between the distribution of the subpopulations found and the functional sperm motility in each step. Except for the 1st and 4th steps, four sperm kinematic subpopulations were observed explaining more than 75% of the variance. Based on velocity and linearity parameters and the subpopulations disclosed, the kinematic response varies among processing steps modifying sperm movement trajectories in a subpopulation specific and handling step-dependent manner (p < 0.001). The predominant motile subpopulation in freshly ejaculated buck sperm had very fast velocity characteristics and a non-linear trajectory (41.1%). Washing buck sperm twice altered the subpopulation structure as well as cooling which resulted in a dramatic reduction in sperm velocities (p < 0.01). Frozen-thawed spermatozoa showed similar characteristics to cooled sperm except there was a further increase in linearity with a large proportion of sperm attributed to new slow, linear cluster (32.5%). In conclusion, this study confirms the variability and heterogeneity of goat sperm kinematic patterns throughout the cryopreservation process and suggests that the predominant motility pattern (assayed in vitro via CASA) of high quality spermatozoa might be typified by high speed and a non linear trajectory. The relationships among the number and distribution of sperm subpopulations and the different handling steps were particularlly relevant, specially after the cooling and the post-thawing steps, when effects derived from these critical handling steps were evident and altered drastically the sperm motion patterns.

AB - BACKGROUND: The influence of metabolic surgery on the glucose and lipid profiles of nonobese body mass index<30 kg/m2 patients with type 2 diabetes, particularly the effect >=1 year, remains unknown. METHODS: PubMed and Ovid Embase were used. SETTING: University hospitals. RESULTS: In total, 21 studies including 921 patients were examined in this systematic review, the results of which revealed decrease in body mass index, waist circumference, fasting plasma glucose, glycosylated hemoglobin A1C, fasting C-peptide, fasting insulin, homeostasis model of assessment for insulin resistance index, triglycerides, total cholesterol, and low-density lipoprotein cholesterol. An increase in high-density lipoprotein cholesterol was also observed. The diabetes remission rates ranged from 13.3% to 90.2% according to 20 studies. The incidence of gastrointestinal bleeding ranged from 1% to 10% according to 9 studies. Four studies reported anemia after Roux-en-Y gastric bypass or one-anastomosis gastric bypass, with the incidence ranging from 8% to 33%. CONCLUSIONS: Nonobese patients can achieve improvements in weight-related indices and glucose and lipid profiles in the short and medium term after metabolic surgery; however, the complications of metabolic surgery warrant further attention. PMID- 29571635 TI - Lack of correlation between gastroesophageal reflux disease symptoms and esophageal lesions after sleeve gastrectomy. AB - BACKGROUND: The postoperative development or worsening of gastroesophageal reflux disease (GERD) represents the major drawback of laparoscopic sleeve gastrectomy (SG). A GERD diagnosis is often based only on symptoms and proton pump inhibitors (PPI) intake, while objective tests like esophagogastroduodenoscopy and pH measurements are performed less frequently. OBJECTIVES: To evaluate the association between reflux symptoms and GERD-related esophageal lesions. SETTINGS: University hospital, Rome, Italy. METHODS: A comprehensive clinical control entailing GERD symptoms, PPI intake, and esophagogastroduodenoscopy was proposed to all patients who underwent SG between June 2007 and February 2011, irrespective of the presence of GERD symptoms. One hundred forty-four of 219 patients agreed to take part in the study (follow-up rate: 65.8%). RESULTS: After a mean follow-up of 66 months, GERD symptoms and PPI intake were recorded in 70.2% and 63.9% of patients, respectively. Mean visual analogue scale score was 2.9 +/- 3.3. The overall frequency of erosive esophagitis was 59.8%, while nondysplastic Barrett's esophagus was detected in 13.1%. The frequency of esophageal biliary reflux was 68%. GERD symptoms and visual analogue scale score were not significantly associated with the development of erosive esophagitis and Barrett's esophagus and the severity of the esophageal lesions. Moreover, the frequency of erosive esophagitis and Barrett's esophagus in patients consuming PPI were similar to that of patients without PPI. CONCLUSION: Symptoms investigation alone is not a reliable tool to diagnose GERD after SG. The use of objective diagnostic tests, such as esophagogastroduodenoscopy, should be carefully considered in the postoperative follow-up schedule of SG patients.

PMID- 29571640 TI - Comparison of Clinical Outcomes Between General Anesthesiologists and Cardiac Anesthesiologists in the Management of Left Ventricular Assist Device Patients in Noncardiac Surgeries and Procedures. AB - OBJECTIVE: To describe the authors' experience and comparative results after introducing noncardiac fellowship-trained anesthesiologists to a service previously managed by fellowship-trained cardiac anesthesiologists caring for left ventricular assist device (LVAD) patients undergoing low-risk noncardiac procedures with anesthesia. DESIGN: A retrospective chart review. SETTING: Single site academic medical center in the United States. INTERVENTIONS: Anesthesia and intraoperative therapy. MEASUREMENTS AND MAIN RESULTS: After initiating a brief training period for the noncardiac fellowship-trained anesthesiologists and blending the noncardiac anesthesiologists into the care of LVAD patients, the electronic medical records of 158 patients with an LVAD who underwent noncardiac procedures were reviewed. The cases were managed by either cardiac-trained anesthesiologists or noncardiac-trained anesthesiologists. Their performance was evaluated on the basis of technique and outcome. The parameters for technique were the use of intubation and mechanical ventilation, use of vasoactive medications, type of vasoactive medications administered, use of invasive monitoring, and type and amount of intravenous fluid administration. The outcomes examined included occurrence of intraoperative mean blood pressure <55 mmHg, intraoperative cardiac arrest, intraoperative device malfunction, thromboembolic complications, inability to complete procedure due to intraoperative nonsurgical complication, unplanned postoperative intensive care unit admission, unplanned hospital readmission within 30 days, and the 30-day postoperative mortality rate. This analysis demonstrated no statistically significant associations between the type of anesthesiologist and the use of fluid, amount of fluid given, use of vasopressors, or use of invasive monitoring devices. There were no significant differences in specific patient outcomes by anesthesia provider type. CONCLUSIONS: Patients with LVADs can be managed by either a noncardiac or a cardiac fellowship-trained anesthesiologist with similar technique and outcome during low-risk noncardiac procedures and surgeries.

PMID- 29571643 TI - Acute Kidney Injury After Total Arch Replacement Combined With Frozen Elephant Trunk Implantation: Incidence, Risk Factors, and Outcome. AB - OBJECTIVES: Acute kidney injury (AKI) is common after thoracic aortic surgery and is a significant predictor of morbidity and mortality. Total arch replacement (TAR) combined with frozen elephant trunk (FET) implantation has been reported to produce satisfactory clinical outcomes, whereas several features of the surgical procedure may induce postoperative AKI. The authors aimed to clarify the incidence of and risk factors for postoperative AKI and the association of AKI with short-term outcomes. DESIGN: This study was a retrospective analysis of a prospectively collected cohort. A multivariate logistic regression model was used to identify predictors of postoperative AKI. SETTING: Single center. PARTICIPANTS: Clinical data were analyzed for 553 consecutive patients who underwent TAR combined with FET implantation between 2013 and 2016. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Postoperative AKI was defined using the Kidney Disease Improving Global Outcomes criteria. Postoperative AKI occurred in 77.6% of the whole cohort. Patients in stage 3 AKI were associated with a higher incidence of major adverse events and in-hospital and 90-day mortality (p < 0.001, p < 0.05, p < 0.01, respectively). In the multivariate analysis, male sex (odds ratio [OR] 1.94; 95% confidence interval [95% CI] 1.22 3.18; p = 0.005); older age (per 10 years) (OR 1.37; 95% CI 1.14-1.67; p = 0.001); elevated body mass index (per 5 kg/m2) (OR 1.41; 95% CI 1.08-1.87; p = 0.01); and prolonged cardiopulmonary bypass duration (per 30 minutes) (OR 1.17; 95% CI 1.01-1.37; p = 0.03) were identified as independent predictors of postoperative AKI. CONCLUSION: TAR combined with FET implantation carries a high risk for postoperative AKI compared with other types of thoracic aortic surgeries. Cardiopulmonary bypass duration was identified as the only modifiable predictor of AKI, and patients may benefit from moderate hypothermic circulatory arrest instead of deep hypothermic circulatory arrest. PMID- 29571644 TI - Large-Scale Implementation of Structured Reporting of Adnexal Masses on Ultrasound. AB - PURPOSE: The aim of this article is to describe the development and implementation of structured reporting of adnexal mass findings on pelvic ultrasound in a large integrated health care delivery system. METHODS: A structured reporting system that includes standardized terminology for describing adnexal masses on ultrasound was developed by a multidisciplinary team of radiologists, gynecologists, and gynecologic oncologists on the basis of literature review and internal data. The system uses a reporting template that requires radiologists to assign abnormal adnexal masses to one of five possible categories on the basis of standardized criteria: category 0, 1, 2, or 3 for masses <10 cm, to reflect increasing concern for malignancy, and category X for masses >10 cm. Unique predefined hashtags were linked to each category to enable electronic data extraction, and a hard stop feature was installed that prevents reports from being finalized without a category designation. In 2014, after a 3 month pilot study, large-scale implementation was supported by an educational campaign consisting of web-based conferences, e-mail announcements, and local presentations. Clinical management recommendations on the basis of category and other clinical factors were provided in a separate practice resource for clinicians. RESULTS: Analysis of adherence revealed that 93% of the approximately 12,000 reports describing abnormal adnexal masses in 2016 included category designations. Feedback from referring providers via an anonymous survey indicated high levels of satisfaction with reports. CONCLUSIONS: Multidisciplinary collaboration and leveraging of technology enabled large-scale implementation of structured reporting with high levels of adherence among radiologists and improved satisfaction among referring providers. PMID- 29571645 TI - Musculoskeletal Injuries Affecting Radiologists According to the 2017 ACR Human Resources Commission Workforce Survey. AB - Practice leaders surveyed in the 2017 ACR Human Resources Commission workforce survey reported that 25% of the radiologists or radiation oncologists they supervised had neck pain, 32% had low back pain, and 16% were dealing with a repetitive stress injury. The prevalence rates of these musculoskeletal ailments among radiologists and radiation oncologists were consistent with those reported in the literature in other populations. However, these prevalence rates may be underestimated because practice leaders, not the radiologists themselves, were surveyed, and the leaders may not be aware of all injuries. PMID- 29571646 TI - Ultrasound and Dual-Energy X-Ray Absorptiometry Report Transcription Error Rates and Strategies for Reduction. AB - PURPOSE: Radiologists play an essential role in patient care by providing accurate and timely results. An error-free radiology report is an expectation of both patients and referring physicians. Software is currently available that can eliminate measurement and side types of errors while saving radiologists and sonographers time. The objectives of this study were to evaluate the potential reduction in report errors, estimate the potential time savings associated with implementation, and conduct a cost-benefit analysis of implementing two software programs. METHODS: Data on the number of measurement errors and side errors in ultrasound and dual-energy x-ray absorptiometry reports were collected, and the time required for data entry that the software would reduce was measured by report type. Generalized estimating equations regression was used to estimate error rates and data entry times and corresponding 95% confidence intervals by report type for radiologists and sonographers. Current wages and report volumes were then applied to the time savings to estimate the annual wage savings. Projected volume increases were applied to the annual estimates to generate a 5 year savings estimate. RESULTS: Overall, measurement errors occurred in 6% to 28% of ultrasound reports, depending on the report type. Side errors were rare. It was estimated that over 5 years, the software could save $693,777 in radiologist wages and $130,771 in sonographer wages, a total of $824,548 (range, $621,866 $1,039,714). CONCLUSIONS: The use of data integration software would both significantly reduce errors in ultrasound and dual-energy x-ray absorptiometry reports and save a considerable amount of time and money.

PMID- 29571650 TI - Early assessment of response to chemotherapy in lung cancer using dynamic contrast-enhanced MRI: a proof-of-concept study. AB - AIM: To evaluate the early treatment response to chemotherapy in patients with lung cancer using dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI). MATERIALS AND METHODS: Twenty-two patients with lung cancer underwent DCE MRI before chemotherapy and 1 week after the start of the first course of chemotherapy. Pharmacokinetic parameters (Ktrans, Kep, and Ve) derived from DCE MRI were generated using the post-processing platform. These parameters and corresponding changes were compared between responders and non-responders after treatment using Student's t or Mann-Whitney U-tests. Diagnostic efficiency of kinetic parameters in differentiating responders from non-responders after 1 week of chemotherapy was also investigated. RESULTS: Thirteen responders after 1 week of chemotherapy had a significant decrease in Ktrans and Ve compared with the pretreatment value (p<0.05), and had no significant changes in Kep (p>0.05). Nine non-responders had no significant changes in Ktrans, Kep, and Ve compared with the pretreatment value (p>0.05). Changes in Ktrans (DeltaKtrans) were significantly larger in responders than that in non-responders (p<0.05). Changes in Ve and Kep (DeltaVe andDeltaKep) were without statistical significance after treatment between responders and non-responders (p>0.05). The cut-off value of DeltaKtrans in best predicting tumour's chemotherapeutic response was 0.032/min and the corresponding AUC (area under the curve), sensitivity, specificity, and accuracy were 0.821, 84.62%, 77.78%, and 81.82%, respectively. CONCLUSION: DCE MRI may be useful for evaluating the early response to chemotherapy in patients with lung cancer, but larger, more definitive studies are needed. PMID- 29571649 TI - Prediction of tumor biological characteristics in different colorectal cancer liver metastasis animal models using 18F-FDG and 18F-FLT. AB - BACKGROUND: Positron emission tomography (PET) is a noninvasive method to characterize different metabolic activities of tumors, providing information for staging, prognosis, and therapeutic response of patients with cancer. The aim of this study was to evaluate the feasibility of 18F-fludeoxyglucose (18F-FDG) and 3'-deoxy-3'-18F-fluorothymidine (18F-FLT) PET in predicting tumor biological characteristics of colorectal cancer liver metastasis. METHODS: The uptake rate of 18F-FDG and 18F-FLT in SW480 and SW620 cells was measured via an in vitro cell uptake assay. The region of interest was drawn over the tumor and liver to calculate the maximum standardized uptake value ratio (tumor/liver) from PET images in liver metastasis model. The correlation between tracer uptake in liver metastases and VEGF, Ki67 and CD44 expression was evaluated by linear regression. RESULTS: Compared to SW620 tumor-bearing mice, SW480 tumor-bearing mice presented a higher rate of liver metastases. The uptake rate of 18F-FDG in SW480 and SW620 cells was 6.07% +/- 1.19% and 2.82% +/- 0.15%, respectively (t = 4.69, P = 0.04); that of 18F-FLT was 24.81% +/- 0.45% and 15.57% +/- 0.66%, respectively (t = 19.99, P < 0.001). Micro-PET scan showed that all parameters of FLT were significantly higher in SW480 tumors than those in SW620 tumors. A moderate relationship was detected between metastases in the liver and 18F-FLT uptake in primary tumors (r = 0.73, P = 0.0019). 18F-FLT uptake was also positively correlated with the expression of CD44 in liver metastases (r = 0.81, P = 0.0049). CONCLUSIONS: The uptake of 18F-FLT in metastatic tumor reflects different biological behaviors of colon cancer cells. 18F-FLT can be used to evaluate the metastatic potential of colorectal cancer in nude mice.

AB - The strain Bifidobacterium choerinum FMB-1, a bacterium with a strong ability to degrade resistant starch (RS), was isolated from rumen fluids of Korean native cattle (Bos taurus coreanae). Degradation experiments revealed that it could degrade approximately 80% of native granular starches within 8 h. Although B. choerinum has strong RS degradation abilities, a completed genomic resource has not yet been proposed. Here we present the complete whole genome data of B. choerinum FMB-1. It consists of a circular chromosome (2,257,294 bp) and one plasmid (11,012 bp). Genome analysis revealed that at least 11 protein-coding genes were related to alpha-glucan degradation. The abundance of these genes may affect the efficacy of granular starch degradation. We also found the existence of antimicrobial resistance genes in the genome, which were not reported in other B. choerinum genomes. The whole genome information of B. choerinum FMB-1 could improve the understanding of the RS degradation mechanism of bovine gut microorganisms. PMID- 29571652 TI - The complete genome sequence of the first hesperiid-infecting alphabaculovirus isolated from the leguminous pest Urbanus proteus (Lepidoptera: Hesperiidae). AB - Baculoviruses are insect viruses largely used as expression vectors and biopesticides. These viruses can efficiently infect the larval stage of several agricultural pests worldwide causing a lethal disease. In this work, we found a novel baculovirus isolated from the larval stage of Urbanus proteus (L.), the bean leafroller and characterized its complete genome. This is an important pest of several leguminous plants in Brazil and belongs to the butterfly family Hesperiidae, from where no baculovirus genome sequence has been described. This new virus was shown to have the smallest genome among all alphabaculoviruses sequenced to date, with 105,555 bp and 119 putative ORFs. We found ten unique genes, seven bro, and the 38 baculovirus core genes. UrprNPV was found to be related to the Adoxophyes-infecting baculoviruses AdorNPV and AdhoNPV with high genetic distance and a long branch length. Interestingly, few individual core gene-based phylogenies were found to support the relationship of UrprNPV to both AdorNPV and AdhoNPV. Importantly, the increase in number of completely sequenced baculovirus points to a very exciting way to understand baculovirus and its evolution and could potentially help the use of baculovirus as both biopesticides and expression vectors.

AB - Based on the co-crystal structures of tubulin with plinabulin and Compound 1 (a derivative of plinabulin), a total of 18 novel plinabulin derivatives were designed and synthesized. Their biological activities were evaluated against human pancreatic cancer BxPC-3 cell lines. Two novel Compounds 13d and 13e exhibited potent activities with IC50 at 1.56 and 1.72 nM, respectively. The tubulin polymerization assay indicated that these derivatives could inhibit microtubule polymerization. Furthermore, the interaction between tubulin and these compounds were elucidated by molecular docking. The binding modes of Compounds 13d and 13e were similar to the co-crystal structure of Compound 1. H pi interaction was observed between the aromatic hydrogen of thiophene moiety with Phe20, which could enhance their binding affinities.

PMID- 29571654 TI - The anuran skin peptide bradykinin mediates its own absorption across epithelial barriers of the digestive tract. AB - When faced with a potential predator, a wide range of frog species secrete a mixture of peptide toxins from their skin to defend themselves. We have recently shown that antimicrobial peptides (AMPs) in a frog's defensive poison enhance the uptake of these peptides across epithelia, thereby speeding up the process of predator intoxication. This study provides evidence that bradykinin, a widespread peptide toxin in anurans (frogs), is capable to pass through epithelial barriers independent of this delivery system. We quantified bradykinin peptides secreted by Bombina orientalis during acute stress, and found that at biologically relevant concentrations, bradykinin passage across model epithelia occurs even in the absence of AMPs. Monitoring of transepithelial electric resistance showed that bradykinin treatment caused a subtle yet prolonged reduction in barrier function, indicating that the peptide itself is capable to increase the permeability of epithelia. Yet, bradykinin does not cause cells to leak lactate dehydrogenase, suggesting that it does not damage cell membranes. Moreover, imaging of bradykinin-treated monolayers shows no endocytosis of fluorescent propidium iodide, indicating that the peptide does not perforate cell membranes at smaller scale and therefore is unlikely to cross epithelia via a transcellular passage. Together, these observations suggest that bradykinin, unlike other amphibian neuropeptide toxins, mediates its own passage across mucosal barriers, possibly through a paracellular route. This "self-administering" property, combined with the fact that bradykinins can potently disturb multiple physiological processes, could explain why these peptides are one of the most widespread antipredator peptides in the defensive secretions of frogs. PMID- 29571656 TI - Detection of major histocompatibility complex molecules in processed allogeneic bone blocks for use in alveolar ridge reconstruction. AB - OBJECTIVES: Because processed allogenic bone blocks contain remnants of cells and other organic material, the present study examined the putative presence of major histocompatibility complex (MHC) molecules in protein extracts derived from processed allogeneic bone blocks. STUDY DESIGN: Protein content and the immunogenic potential of 3 different processed allografts (Osteograft, DIZG, Berlin, Germany; Caput femoris, DIZG, Berlin, Germany; Human Spongiosa, Charite Tissue Bank, Berlin, Germany) were assessed by protein extraction and analysis of the presence of MHC class 1 and 2 molecules prior to grafting. MHC concentration was measured by using enzyme-linked immunosorbent assay. RESULTS: Protein content in the allograft materials varied between 0.87 and 1.61 ug protein/mg. In the allograft Human Spongiosa, no MHC was detected, whereas in the allogeneic bone blocks Osteograft and Caput femoris MHC 1 (0.04-0.037 ng/mg graft material) and in Osteograft MHC class 2 molecules were detectable. CONCLUSIONS: The results of the present study suggest that despite thorough processing, a potential antigenicity of allografts is not eliminated. MHC molecules in allografts may sensitize the immune system.

PMID- 29571658 TI - Cryopreservation of testicular tissue in pre-pubertal and adolescent boys at risk for infertility: A low risk procedure. AB - INTRODUCTION: Cryopreservation of testicular tissue (TT) has become an increasingly attractive option for fertility preservation (FP), particularly for pre-pubertal boys at risk for gonadotoxicity from cancer therapy. At our institution, all at-risk families undergo counseling regarding infertility risk and available FP strategies, including this vulnerable patient population. As the technology required to use the acquired tissue is, as yet, unproven, it is paramount to document minimal morbidity and complications from this procedure. Herein, we report these outcomes for all pre-pubertal patients who have undergone TT biopsies for FP. METHODS: We retrospectively reviewed consecutive patients who underwent unilateral open TT biopsies between January 2014 and December 2016. Patient diagnosis, age, concomitant procedures, anesthetic type, complications, procedure times, planned therapy, and bleeding were evaluated. RESULTS: Of a total of 34 patients, mean age at biopsy was 6.9 +/- 4.4years. Diagnoses included: leukemia/lymphoma (n = 12), solid tumors (n = 15) and non-neoplastic disorders (hemophagocytic lymphohistiocytosis, aplastic anemia; n = 7). Twenty two patients (64.7%) were scheduled for stem cell transplantation. Eleven (32.4%) patients had not received any chemotherapy prior to TT biopsy, while all others had exposure preceding the biopsy. Biopsies were performed in conjunction with other procedures (central line placement, bone marrow biopsy, lumbar puncture, lymph node biopsy) in 29 cases (85.3%), with stand-alone procedures performed in the remainder (n = 5). In stand-alone cases, mean anesthetic time was 22 +/- 8.7 min. Overall, two (5.9%) patients had complications after biopsy: 1) ipsilateral epididymo-orchitis (resolved with antibiotics) and 2) ipsilateral torsed appendix testis (managed conservatively) (Table). CONCLUSION: In this series, pre-pubertal TT biopsy for cryopreservation was safely performed, and was most often coordinated concomitantly with other medically necessary procedures. The safety profile reported herein supports performing this procedure while technological advances fulfill the requirements to make it a viable option for future fertility.

PMID- 29571661 TI - Whole-Exome Sequencing Identifies Two Discrete Druggable Signaling Pathways in Follicular Thyroid Cancer. AB - BACKGROUND: Thyroid cancer is the most common endocrine malignancy, with continuously increasing incidence. Follicular thyroid cancer (FTC) accounts for approximately 10% to 15% of these cases and is known to be associated with several gene mutations. The purpose of this study was to identify novel therapeutic targets in FTC using whole-exome sequencing (WES) and bioinformatics analysis. STUDY DESIGN: Whole-exome sequencing was performed on 6 established FTC cell lines. Stringent false-proof filtering and exclusion of synonymous and known polymorphisms yielded novel missense, nonsense, and splice-site single nucleotide variants (SNV). Gene variants were analyzed for structural, functional, and evolutionary properties using GO (Gene Ontology), Pfam (Protein Families), and KEGG (Kyoto Encyclopedia of Genes and Genomes) searches by STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) and GORILLA (Gene Ontology enRIchment anaLysis and visuaLizAtion tool) analyses. A false discovery rate of <0.5 was used to denote significantly enriched signaling pathways. RESULTS: An average of 657 (range 366 to 1,158) SNVs including 31 (range 12 to 53) known cancer driver genes were identified in FTC cell line exomes. The SNV burden, distribution, frequency, and signature followed the known thyroid mutation profiles, without chromosomal bias. Recurrently mutated cancer driver genes included FRG1 (6/6), CDC27, NCOR1, PRSS1 (5/6), AHCTF1, MUC20, PABPC1, and PABPC3 (4/6). Pathway analysis using bioinformatics tools STRING and GORILLA segregated FTC cell lines into 2 druggable signaling groups showing dominant RAS/ERK1-2/AKT and CDK1/CyclinB signaling pathway targets. CONCLUSIONS: Next-generation sequencing tools can be used to identify druggable signaling targets for precision treatment of FTCs.

AB - It is often said that there are two types of psychological processes: one that is intentional, controllable, conscious, and inefficient, and another that is unintentional, uncontrollable, unconscious, and efficient. Yet, there have been persistent and increasing objections to this widely influential dual-process typology. Critics point out that the 'two types' framework lacks empirical support, contradicts well-established findings, and is internally incoherent. Moreover, the untested and untenable assumption that psychological phenomena can be partitioned into two types, we argue, has the consequence of systematically thwarting scientific progress. It is time that we as a field come to terms with these issues. In short, the dual-process typology is a convenient and seductive myth, and we think cognitive science can do better. PMID- 29571665 TI - Is the Type 1/Type 2 Distinction Important for Behavioral Policy?

PMID- 29571666 TI - Presence of Clostridium difficile in poultry and poultry meat in Egypt. AB - C. difficile has been recognized as a potential zoonotic agent encouraging investigations of C. difficile prevalence and ribotypes in animals. Here we report the prevalence and diversity of Egyptian C. difficile in I) samples from healthy poultry (n = 50), II) samples from diseased poultry (n = 54), and III) poultry meat (n = 150). Thirteen isolates were obtained from seven healthy and five diseased animals, but no C. difficile was cultured from poultry meat. The isolated C. difficile strains belonged to 3 different PCR-ribotypes (039/2, 205 and 001/FLI01). The detection of strains related to RT 001 known for its ability to cause disease in humans makes poultry a potential reservoir for pathogenic C. difficile.

AB - BACKGROUND: To investigate the feasibility and outcomes of Impella 2.5 support in patients with severe aortic valve stenosis (AS) and cardiogenic shock (CS), who underwent emergency percutaneous balloon aortic valvuloplasty (BAV) with or without percutaneous coronary intervention (PCI). METHODS AND RESULTS: We retrospectively analyzed a consecutive series of patients with severe AS and CS who underwent Impella 2.5 support following emergency BAV with or without subsequent PCI. Outcome data included 30-day outcomes, periprocedural as well as throughout the circulatory support period complications. Eight patients with severe AS and CS were identified. Impella 2.5 implantation was successful following emergency BAV in all patients attempted. Additional PCI was performed in four patients. No periprocedural deaths or periprocedural neurologic events occurred. Mean procedure time was 125.9 min (range 64-210 min). Mortality at 30 days was 50%. CONCLUSIONS: Impella 2.5 can be used as hemodynamic support in patients with severe AS and CS following emergency percutaneous BAV and may help to improve tolerability of PCI in these high-risk patients. PMID- 29571668 TI - Odor preference and olfactory memory are impaired in Olfaxin-deficient mice. AB - Olfaxin, which is a BNIP2 and Cdc42GAP homology (BCH) domain-containing protein, is predominantly expressed in mitral and tufted (M/T) cells in the olfactory bulb (OB). Olfaxin and Caytaxin, which share 56.3% amino acid identity, are similar in their glutamatergic terminal localization, kidney-type glutaminase (KGA) interaction, and caspase-3 substrate. Although the deletion of Caytaxin protein causes human Cayman ataxia and ataxia in the mutant mouse, the function of Olfaxin is largely unknown. In this study, we generated Prune2 gene mutant mice (Prune2Ex16-/-; knock out [KO] mice) using the CRISPR/Cas9 system, during which the exon 16 containing start codon of Olfaxin mRNA was deleted. Exon 16 has 80 nucleotides and is contained in four of five Prune2 isoforms, including PRUNE2, BMCC1, BNIPXL, and Olfaxin/BMCC1s. The levels of Olfaxin mRNA and Olfaxin protein in the OB and piriform cortex of KO mice significantly decreased. Although Prune2 mRNA also significantly decreased in the spinal cord, the gross anatomy of the spinal cord and dorsal root ganglion (DRG) was intact. Further, disturbance of the sensory and motor system was not observed in KO mice. Therefore, in the current study, we examined the role of Olfaxin in the olfactory system where PRUNE2, BMCC1, and BNIPXL are scarcely expressed. Odor preference was impaired in KO mice using opposite-sex urinary scents as well as a non-social odor stimulus (almond). Results of the odor-aversion test demonstrated that odor-associative learning was disrupted in KO mice. Moreover, the NMDAR2A/NMDAR2B subunits switch in the piriform cortex was not observed in KO mice. These results indicated that Olfaxin may play a critical role in odor preference and olfactory memory. PMID- 29571669 TI - Chronic lymphocytic leukemia and infection risk in the era of targeted therapies: Linking mechanisms with infections. AB - Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the world. Patient with CLL are at particular risk for infections due to inherent disease-related immune dysfunction in addition to the effect of certain systemic therapies on the immune system. The advent of B-cell receptor (BCR) inhibitors such as ibrutinib and idelalisib has led to a practice change that utilizes these targeted agents in the treatment of CLL, either in place of chemoimmunotherapy (CIT) or in later line settings. In this paper, we review the pathophysiology of immune dysfunction in CLL, the spectrum of immunodeficiency with the various therapeutic agents along with prevention strategies with a focus on targeted therapies. PMID- 29571670 TI - Maxillary tumour-induced osteomalacia. AB - Tumour-induced osteomalacia (TIO) is a rare paraneoplastic form of renal phosphate wasting that results in severe hypophosphatemia, defective vitamin D metabolism, and osteomalacia. In the case reported here, maxillary TIO was not diagnosed for 6years, although initial complaints were reported when the patient was 12years old. Meanwhile she suffered from profound growth limitation, pain, weakness, and spontaneous multiple bone fractures, culminating in complete loss of ambulatory ability and severe limitation in daily activities. At age 18years, she finally received an accurate diagnosis and definitive treatment was administered. She underwent a partial maxillectomy with complete removal of the tumour, resulting in a full cure. Shortly afterwards the patient regained the ability to walk, no longer needing the wheelchair to which she had been confined. This definitive diagnosis was based on three modalities: (1) fibroblast growth factor 23 analysis (high levels of the secreted hormone were found on the left side of the maxilla in the facial vein and pterygoid plexus, pinpointing the tumour location), (2) octreotide scan, and (3) 68Ga-DOTA-NOC-PET/CT. TIO removal via partial maxillectomy led to a complete reversal of this patient's health condition, restoring her ability to walk and function. The importance of prompt employment of these diagnostic modalities and the high level of clinical suspicion required in such cases are clear. PMID- 29571671 TI - Impact of particulate deproteinized bovine bone mineral and porous titanium granules on early stability and osseointegration of dental implants in narrow marginal circumferential bone defects. AB - The use of two particulate bone graft substitute materials in experimental narrow marginal peri-implant bone defects was investigated with respect to early bone healing and implant stability. Porous titanium granules, oxidized white porous titanium granules (WPTG), and demineralized bovine bone mineral (DBBM) were characterized in vitro, after which the two latter materials were tested in experimental peri-implant bone defects in six minipigs, with empty defects as control. After mandibular premolar extraction, the top 5mm of the alveoli were widened to 6mm in diameter, followed by the placement of six implants, three on each side, in each pig. Six weeks of healing was allowed. The WPTG showed better mechanical properties. No significant differences in resonance frequency analysis were found directly after compacting or healing, and similar quantities of defect bone formation were observed on micro-computed tomography for all groups. Histomorphometric analysis demonstrated a more coronal bone-to-implant contact in the DBBM group, which also displayed more defect bone fill as compared to the WPTG group. The better mechanical properties observed for WPTG appear of negligible relevance for the early stability and osseointegration of implants.

AB - Enumeration techniques were compared for quantification of the South African isolate of Cryptophlebia leucotreta granulovirus (CrleGV-SA), used as a biopesticide to control false codling moth (Thaumatotibia leucotreta), an insect pest of various fruits and nuts, including citrus. The routine enumeration method for CrleGV-SA virus particles in experimentation and production of CrleGV-SA biopesticides is dark field microscopy. This method was compared with spectrophotometry, scanning electron microscopy (SEM) and real time quantitative polymerase chain reaction (qPCR). The purpose was to develop an accurate and reliable routine enumeration method for CrleGV-SA occlusion bodies (OBs) and to validate the use of dark field microscopy. Purified and semi-purified CrleGV-SA viral stocks were used. Spectrophotometry was not a suitable or accurate enumeration method. Dark field microscopy and SEM were accurate and statistically comparable (p = 0.064), validating the use of dark field microscopy as an enumeration method for granulovirus (GV). However, SEM has superior resolution and the advantage of easily distinguishing virus particles from debris in semi purified viral stock preparations. A quantitative PCR technique has been developed based on use of specific oligonucleotide primers for the granulin gene. This has the advantage of not being affected by contamination with non-biological debris or biological material, which impact on the other methods. PMID- 29571680 TI - Intimate partner violence during pregnancy and behavioral problems in children and adolescents: a meta-analysis. AB - OBJECTIVE: To evaluate the association of intimate partner violence during the gestational period and the development of externalizing and internalizing behavioral problems in children and adolescents. SOURCE OF DATA: A meta-analysis of cohort and case-control studies was performed, using studies selected from electronic databases. Eligible studies included women who experienced intimate partner violence during pregnancy and their children's behavioral problems. These problems encompass two groups: externalizing problems (expressed by hyperactivity, aggressive and challenging behavior, and delinquency) and internalizing problems (represented by depressive moods, anxiety, and somatic symptoms). The risk of bias was assessed by the Newcastle-Ottawa Quality Assessment Scale (NOS) and the quality of evidence by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). RevMan 5.3 software was used for the meta-analysis. DATA SYNTHESIS: Of the 687 eligible articles, only seven met all inclusion criteria and consisted of 12,250 mother/child pairs. The age range of the assessed children varied from 10 months to 16 years. The odds of internalizing problems in children exposed to prenatal violence were two-fold higher (OR=2.10, 95% CI: 1.17-3.76) and that of externalizing problems were 1.9-fold higher (95% CI: 1.28-2.83), when compared to children of unexposed mothers. CONCLUSION: The results of this study are consistent with the hypothesis that women's exposure to intimate partner violence during pregnancy may be associated with behavioral problems of their children, emphasizing the need for greater understanding about the vulnerability of children to adversity in early ages. PMID- 29571681 TI - Randomized clinical trial to change parental practices for drug use in a telehealth prevention program: a pilot study. AB - OBJECTIVES: Programs for parents have been found to have a direct positive impact on reducing the consumption of psychoactive substances by adolescents, as well as having an indirect impact on reducing risk factors and increasing protective factors. The present study aimed to verify if a telehealth prevention program based on a brief motivational intervention helps to reduce parental risk practices and increase parental protective practices for drug use in comparison with psychoeducation. METHODS: A pilot randomized controlled trial was performed at the National Service of Guidance and Information on Drug Use (Ligue 132), from September 2014 to December 2015, with the parents of adolescents (n=26). The outcome measures were parental style, risk, and protective parental practices. RESULTS: The brief motivational intervention was found to be more effective than psychoeducation in reducing the negligent behavior of parents. Furthermore, when comparing pre- and post-intervention data, the brief motivational intervention helped to change parental style and the large majority of parental practices: increasing positive monitoring, as well as decreasing physical abuse, relaxed discipline, inconsistent punishment, and negative monitoring. CONCLUSIONS: These results demonstrate that the telehealth intervention is effective in modifying the parental practices known to help in preventing drug use. Studies with more number of subjects are required so that the results can be substantiated and generalized. PMID- 29571682 TI - Protocol to obtain targeted transcript sequence data from snake venom samples collected in the Colombian field. AB - Snake venoms are a mixture of different molecules that can be used in the design of drugs for various diseases. The study of these venoms has relied on strategies that use complete venom extracted from animals in captivity or from venom glands that require the sacrifice of the animals. Colombia, a country with political and geographical conflicts has difficult access to certain regions. A strategy that can prevent the sacrifice of animals and could allow the study of samples collected in the field is necessary. We report the use of lyophilized venom from Crotalus durissus cumanensis as a model to test, for the first time, a protocol for the amplification of complete toxins from Colombian venom samples collected in the field. In this protocol, primers were designed from conserved region from Crotalus sp. mRNA and EST regions to maximize the likelihood of coding sequence amplification. We obtained the sequences of Metalloproteinases II, Disintegrins, Disintegrin-Like, Phospholipases A2, C-type Lectins and Serine proteinases from Crotalus durissus cumanensis and compared them to different Crotalus sp sequences available on databases obtaining concordance between the toxins amplified and those reported. Our strategy allows the use of lyophilized venom to obtain complete toxin sequences from samples collected in the field and the study of poorly characterized venoms in challenging environments.

AB - PURPOSE: To investigate the effectiveness of a home-based social media use intervention to enhance the social networks of rural youth with disabilities. METHOD: Participants were nine youth (mean age = 17.0 years) with disabilities from two rural Australian communities. The intervention consisted of providing appropriate assistive technology and social media training on individualised goals. Using mixed methods, quantitative (a single group pre-post) and qualitative (interviews with participants and their carers) measures were used to examine outcomes of training, individual experiences of the intervention, and changes to online social networks. RESULTS: Participants increased their performance and satisfaction with performance on social media problem areas post intervention; paired t-tests showed statistical significance at p < .001. There was also a significant increase in the number of online communication partners; Wilcoxon Signed Ranks showed statistical significance at p < .05. The interviews highlighted increased social participation, independence and improvements to literacy. Ongoing parental concerns regarding cyber safety and inappropriate online content were noted. CONCLUSIONS: The findings suggest that social media training is a feasible method for increasing social networks among rural-based youth with disabilities. To sustain ongoing benefits, parents need knowledge and training in integrating assistive technology and social media.

AB - OBJECTIVE: This study established the validity and reliability of the Healthy Families Survey, a 45-item survey measuring nutrition and physical activity behaviors among children and parents enrolled in the Maryland Supplemental Nutrition Assistance Program-Education. METHODS: Analysis included 1,376 pretest surveys. A factor analysis was conducted to establish construct validity, item analyses were conducted to determine item relevance for the target population, and Cronbach alpha was established to assess internal reliability. RESULTS: The factor analysis extracted 9 factors, with 91% of variables loading appropriately (>+0.30 loading) onto factors. Item analyses identified 6 variables with low (<0.20) or high (>0.80) mean values at baseline. Seven of the 9 subscales had Cronbach alpha >= .60. CONCLUSIONS AND IMPLICATIONS: The Healthy Families Survey demonstrated both strong construct validity and internal reliability and can be used by Supplemental Nutrition Assistance Program-Education agencies to assess child and parent nutrition and physical activity behaviors.

AB - Guinier analysis allows model-free determination of the radius of gyration (Rg) of a biomolecule from X-ray or neutron scattering data, in the limit of very small scattering angles. Its range of validity is well understood for globular proteins, but is known to be more restricted for unfolded or intrinsically disordered proteins (IDPs). We have used ensembles of disordered structures from molecular dynamics simulations to investigate which structural properties cause deviations from the Guinier approximation at small scattering angles. We find that the deviation from the Guinier approximation is correlated with the polymer scaling exponent nu describing the unfolded ensemble. We therefore introduce an empirical, nu-dependent, higher-order correction term, to augment the standard Guinier analysis. We test the new fitting scheme using all-atom simulation data for several IDPs and experimental data for both an IDP and a destabilized mutant of a folded protein. In all cases tested, we achieve an accuracy of the inferred Rg within ~3% of the true Rg. The method is straightforward to implement and extends the range of validity to a maximum qRg of ~2 versus ~1.1 for Guinier analysis. Compared with the Guinier or Debye approaches, our method allows data from wider angles with lower noise to be used to analyze scattering data accurately. In addition to Rg, our fitting scheme also yields estimates of the scaling exponent nu in excellent agreement with the reference nu determined from the underlying molecular ensemble.

AB - OBJECTIVES: To identify non-surgical treatments which were deemed to be more effective in improving dynamic postural control in patients with chronic ankle instability (CAI). DESIGN: Systematic review and random-effects network meta analysis. METHODS: We searched Scopus, CENTRAL, and PubMed until 26 August 2017. We used data from randomized trials comparing the results of different non surgical interventions for lateral CAI. We assessed dynamic postural control in terms of the star-excursion balance test in the posteromedial direction. We evaluated this outcome at the end of the rehabilitation protocols (i.e., short term) and 6months after treatment (i.e., medium term). We assessed the quality of the included studies with the Cochrane risk of bias tool and evaluated the quality of evidence from the network of interventions using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. RESULTS: Nineteen trials were eligible for inclusion in this systematic review. A 4-6-week supervised balance training program and a 4-6-week strengthening rehabilitation protocol provided significant improvements compared to control (8 studies, standardized mean difference [SMD] was -0.75, 95% CIs [-1.28 to -0.23]); and 2 studies, SMD was -1.2, 95% CIs [-2.36 to -0.08], respectively). A 6-week combined intervention that addressed balance and strength had the highest probability of being among the best treatments. However, the latter rehabilitation intervention was included in only one trial. CONCLUSIONS: The network meta-analysis showed that supervised balance training protocols and strengthening programs significantly improved dynamic balance in patients with CAI. A combination of these interventions may further increase the efficacy of non-surgical treatment options for the first-line management of CAI. PMID- 29571698 TI - Perfusion MR imaging at 3-Tesla: Can it predict tumor grade and histologic necrosis rate of musculoskeletal sarcoma? AB - PURPOSE: To identify quantitative perfusion parameters that are best associated with tumor grade and tumor necrosis at magnetic resonance (MR) imaging at 3 Tesla. METHODS: MR perfusion studies of 31 patients with a musculoskeletal sarcoma were retrospectively evaluated by two readers. There were 18 men and 13 women with a mean age of 34.9+/-24.4 (standard deviation [SD] years) (range: 6-87 years). All patients underwent carcinologic tumor resection less than 3 months after MR imaging. For all patients six perfusion parameters (three semi quantitative and three permeability parameters) were analyzed. The percentage of tumor necrosis was estimated using MR imaging. Perfusion data were compared between groups of tumors with different grades and necrosis ratios. Interobserver variability was calculated using intraclass correlation coefficient (ICC). RESULTS: Interobserver variability among the perfusion parameters was good to excellent (ICC: 0.72-0.9). The area under the curve and maximum slope values showed a significant association with the degree of tumor necrosis (P=0.02-0.04). When tumors with low necrosis ratios were compared to those with high ratios the former parameter was 80% lower. In the same groups, the imaging necrosis index was 56.9-59.8% higher in patients with grade 2 necrosis (P=0.01). Extracellular space volume (Ve) was 31.4% to 55.8% lower in tumors with high grade while the backflow constant (Kep) was 33.6% to 40.1%% higher in tumors with high grade. CONCLUSION: Semi-quantitative MR perfusion parameters have an excellent reproducibility and are associated with the degree of histologic tumor necrosis in musculoskeletal sarcomas. The utility of permeability parameters for determining tumor grade needs further investigations. PMID- 29571699 TI - Diffusion-weighted magnetic resonance imaging of extraocular muscles in patients with Grave's ophthalmopathy using turbo field echo with diffusion-sensitized driven-equilibrium preparation. AB - PURPOSE: The purpose of this study was to correlate diffusivity of extraocular muscles, measured by three-dimensional turbo field echo (3DTFE) magnetic resonance (MR) imaging using diffusion-sensitized driven-equilibrium preparation, with their size and activity in patients with Grave's ophthalmopathy. MATERIALS AND METHODS: Twenty-three patients with Grave's ophthalmopathy were included. There were 17 women and 6 men with a mean age of 55.8+/-12.6 (SD) years (range: 26-83 years). 3DTFE with diffusion-sensitized driven-equilibrium MR images were obtained with b-values of 0 and 500s/mm2. The apparent diffusion coefficient (ADC) of extraocular muscles was measured on coronal reformatted MR images. Signal intensities of extraocular muscles on conventional MR images were compared to those of normal-appearing white matter, and cross-sectional areas of the muscles were also measured. The clinical activity score was also evaluated. Statistical analyses were performed with Pearson correlation and Mann-Whitney U tests. RESULTS: On 3DTFE with diffusion-sensitized driven-equilibrium preparation, the mean ADC of the extraocular muscles was 2.23+/-0.37 (SD)*10 3mm2/s (range: 1.70*10-3-3.11*10-3mm2/s). There was a statistically significant moderate correlation between ADC and the size of the muscles (r=0.61). There were no statistically significant correlations between ADC and signal intensity on conventional MR and the clinical activity score. CONCLUSION: 3DTFE with diffusion sensitized driven-equilibrium preparation technique allows quantifying diffusivity of extraocular muscles in patients with Grave's ophthalmopathy. The diffusivity of the extraocular muscles on 3DTFE with diffusion-sensitized driven equilibrium preparation MR images moderately correlates with their size.

AB - PURPOSE: To compare imaging findings on thoracic computed tomography (CT) examination in patients with primary spontaneous pneumothorax (SP), depending on their tobacco and/or cannabis consumption. MATERIALS AND METHODS: A total of 83 patients who had thoracic CT for primary SP were prospectively included. There were 65 men and 18 women with a median age of 33 years (IQR: 27; 44 years). The patients were further categorized into three groups according to their smoking habits. Thirteen patients were non-smokers, 38 were tobacco only smokers and 32 were tobacco and cannabis smokers. CT examinations were retrospectively reviewed for the presence of blebs, centrilobular and paraseptal emphysema and lung nodules in each group for comparison. RESULTS: Emphysema was detected in 43/85 patients (51.8%), including 1/13 patients (7.7%) in the non-smoking group, 19/38 patients (50%) in the tobacco only group and 23/32 patients (71.9%) in the tobacco and cannabis smokers, with no difference between tobacco only and tobacco and cannabis smokers. No differences in type and location of emphysema was found between tobacco only and tobacco and cannabis smokers. Tobacco and cannabis smokers with emphysema were significantly younger than tobacco only smokers with emphysema (35 vs. 46 years, respectively) (P=0.009). CONCLUSION: The prevalence of emphysema visible on CT is not different between tobacco and tobacco/cannabis smokers, however, it occurs at a younger age in tobacco and cannabis smokers. This result suggests that cannabis, when added to tobacco, may lead to emphysema at a younger age. PMID- 29571701 TI - Edaravone in the treatment of amyotrophic lateral sclerosis. PMID- 29571702 TI - Competing trends of ROS and RNS-mediated protein modifications during hypoxia as an alternate mechanism of NO benefits. AB - Hypoxia, especially altitude associated hypoxia is known to cause severe physiological alterations and life-threatening conditions. Impaired redox balance along with oxidative stress, protein carbonylation and instigation of apoptotic events are common sub-cellular events that follow the hypoxic insult. The role of nitric oxide (NO) is very dynamic and versatile in preventing the ill effects of hypoxia vis-a-vis reacting with oxidative species and causing protein nitrosylation. Although several mechanisms of NO-mediated cytoprotection are known during hypoxic insult, limited pieces of evidence are available to support the relationship between two downstream events of oxidative stress, protein carbonylation (caused by carbonyl; CO radical) and protein nitrosylation/nitration (caused by NO/peroxynitrite; ONOO radical). In this study, we investigated an entirely new aspect of NO protection in hypoxia involving crosstalk between carbonylation and nitrosylation. Using standard NO inhibitor l-NAME and simulated hypoxic conditions in hypoxia-sensitive cell line H9c2, we evaluated the levels of radicals, cell death, mitochondrial membrane potential, levels of protein nitrosylation, protein nitration and carbonylation and glutathione content. The results were then carefully analyzed in light of NO bioavailability. Our study shows that reducing NO during hypoxia caused cell death via the increased degree of carbonylation in proteins. This provides a new aspect of NO benefits which furthers opens new possibilities to explore potential mechanisms and effects of cross-talk between nitrosylation, protein nitration and carbonylation, especially through some common antioxidant mediators such as glutathione and thioredoxin. PMID- 29571703 TI - Isolation and molecular characterization of a relapsing fever Borrelia recovered from Ornithodoros rudis in Brazil. AB - In South America, early reports from more than 50 years ago incriminated Ornithodoros rudis as vector of Borrelia venezuelensis, an agent of tick-borne relapsing fever (TBRF). Herein we report the rediscovery of O. rudis by means of morphological, biological and molecular analyses, which also comprise the first report of this tick species in Brazil. Phylogenetic analysis using partial fragments of mitochondrial 16S rRNA gene suggested that O. rudis forms a monophyletic group with Ornithodoros erraticus. By using laboratory rodents as hosts, we isolated a relapsing fever Borrelia from an infected O. rudis female. Phylogenetic analysis inferred from the rrs, flaB, and glpQ genes of Borrelia spp. placed the spirochete harbored by O. rudis closely related to Borrelia turicatae. Until further genetic evidence is not obtained we are referring to this O. rudis spirochete as B. venezuelensis. This is the first in vitro isolation of a TBRF Borrelia from South America. The presence of O. rudis in Brazil should not be overlooked, since this tick has been historically implicated in human cases of TBRF in Colombia, Panama, and Venezuela. This study provides new reports of O. rudis and B. venezuelensis after decades of scientific silence on these agents. PMID- 29571704 TI - Method development and optimization for the determination of benzene, toluene, ethylbenzene and xylenes in water at trace levels by static headspace extraction coupled to gas chromatography-barrier ionization discharge detection. AB - Benzene, toluene, ethylbenzene, and xylenes, more commonly named BTEX, represent one of the most ubiquitous and hazardous groups of atmospheric pollutants. The goal of our research was the trace quantification of BTEX in water by using a new simple, low-cost, and accurate method, based on headspace (HS) extraction and gas chromatography (GC) coupled to barrier ionization discharge detector (BID). This water application dealt with simple matrices without protein, fat, or humic material that adsorb target analytes, thus the external standard calibration was suitable to quantify each compound. The validation steps included the study of linearity, detection and quantification limits, and accuracy. LODs and LOQs varied from 0.159 to 1.845 MUg/L and from 0.202 to 2.452 MUg/L, respectively. The recovery was between 0.74 +/- 0.13 and 1.15 +/- 0.09; relative standard deviations (% RDSs) were less than 12.81% (n = 5) and 14.84% (n = 10). Also, GC performance was evaluated in term of efficiency, peak tailing and resolution. Preliminary results from practical applications to analyses of real samples are presented. The results indicate that static HS coupled to GC-BID is a successful method for BTEX analysis in water samples at the MUg/L levels, provided that hydrocarbons interference occur at similar concentration levels. GC-BID may become a routine reference method alongside the official analytical techniques for quality control purposes of contaminated waters. Moreover, the new method is amenable to automation by using commercial HS units. PMID- 29571705 TI - Optimal human and system performance during neonatal resuscitation. AB - Performance in the delivery of care to sick neonates in need of resuscitation has long been defined primarily in terms of the extent of the knowledge possessed and hands-on skill demonstrated by physicians and other healthcare professionals. This definition of performance in neonatal resuscitation is limited by its focus solely on the human beings delivering care and a perceived set of the requisite skills to do so. This manuscript will expand the definition of performance to include all of the skill sets that humans must use to resuscitate newborns as well as the often complex systems in which those humans operate while delivering that care. It will also highlight how the principles of human factors and ergonomics can be used to enhance human and system performance during patient care. Finally, it will describe the role of simulation and debriefing in the assessment of human and system performance. PMID- 29571706 TI - Prophylactic and early targeted treatment of patent ductus arteriosus. AB - Treatment of a haemodynamically significant patent ductus arteriosus (PDA) in the very preterm infant has been an accepted approach for several decades. However, the rationale for closure of PDA has recently been challenged due to reports of success with conservative approaches and the lack of evidence for longer-term benefits from treatment. In this article, we address an approach to assess treatment of those babies most likely to benefit. PMID- 29571707 TI - Synergistic approaches unraveling regulation and aggregation of intrinsically disordered beta-amyloids implicated in Alzheimer's disease. AB - Alzheimer's disease is a severe brain illness that causes vast numbers of nerve cells in the brain to die, driven by the production and deposition of amyloid beta (Abeta) peptides. Intrinsically disordered proteins (IDPs) generally lack stable structures and are abundant in nature. Abeta peptide is a well-known IDP with a wide range of oligomeric forms. Dysfunctions in Abeta lead to oligomerization, formation of fibrils, and neurodegenerative disorders or other forms of dementia. In this study, we used replica exchange molecular dynamics (REMD) to elucidate the roles of different osmolytes, particularly urea and trimethylamine N-oxide (TMAO), to study shifts in IDP populations. REMD samples the conformational space efficiently and at physiologically relevant temperatures, compared to conventional molecular dynamics that sample at a constant temperature. Urea is known to minimize the aggregation process, while TMAO is beneficial for its stabilizing action. The two osmolytes displayed characteristic effects on Abeta peptides and resulted in progressive modulation of conformations. The present study underlines the hypothesis of "modulation of conformational ensembles" to explain the regulation and aggregation of IDPs. PMID- 29571708 TI - High dimensional random walks can appear low dimensional: Application to influenza H3N2 evolution. AB - One important feature of the mammalian immune system is the highly specific binding of antigens to antibodies. Antibodies generated in response to one infection may also provide some level of cross immunity to other infections. One model to describe this cross immunity is the notion of antigenic space, which assigns each antibody and each virus a point in Rn. Past studies using hemagglutination data have suggested the dimensionality of antigenic space, n, is low. We propose that influenza evolution may be modeled as a Gaussian random walk. We then show that hemagluttination data would be consistent with a walk in very high dimensions. The discrepancy between our result and prior studies is due to the fact that random walks can appear low dimensional according to a variety of analyses including principal component analysis (PCA) and multidimensional scaling (MDS). A high dimensionality of antigenic space is of importance to modelers, as it suggests a smaller role for pre-existing immunity within the host population. PMID- 29571709 TI - Identifying essential proteins based on sub-network partition and prioritization by integrating subcellular localization information. AB - Essential proteins are important participants in various life activities and play a vital role in the survival and reproduction of living organisms. Identification of essential proteins from protein-protein interaction (PPI) networks has great significance to facilitate the study of human complex diseases, the design of drugs and the development of bioinformatics and computational science. Studies have shown that highly connected proteins in a PPI network tend to be essential. A series of computational methods have been proposed to identify essential proteins by analyzing topological structures of PPI networks. However, the high noise in the PPI data can degrade the accuracy of essential protein prediction. Moreover, proteins must be located in the appropriate subcellular localization to perform their functions, and only when the proteins are located in the same subcellular localization, it is possible that they can interact with each other. In this paper, we propose a new network-based essential protein discovery method based on sub-network partition and prioritization by integrating subcellular localization information, named SPP. The proposed method SPP was tested on two different yeast PPI networks obtained from DIP database and BioGRID database. The experimental results show that SPP can effectively reduce the effect of false positives in PPI networks and predict essential proteins more accurately compared with other existing computational methods DC, BC, CC, SC, EC, IC, NC. PMID- 29571710 TI - A 1D model of leukocyte adhesion coupling bond dynamics with blood velocity. AB - Cell adhesion on the vascular wall is a highly coupled process where blood flow and adhesion dynamics are closely linked. Cell dynamics in the vicinity of the vascular wall is driven mechanically by the competition between the drag force of the blood flow and the force exerted by the bonds created between the cell and the wall. Bonds exert a friction force. Here, we propose a mathematical model of such a competitive system, namely leukocytes whose capacity to create bonds with the vascular wall and transmigratory ability are coupled by integrins and chemokines. The model predicts that this coupling gives rise to a dichotomic cell dynamic, whereby cells switch from sliding to firm arrest, through non linear effects. Cells can then transmigrate through the wall. These predicted dynamic regimes are compared to in-vitro trajectories of leukocytes. We expect that competition between friction and drag force in particle dynamics (such as shear stress-controlled nanoparticle capture) can lead to similar dichotomic mode. PMID- 29571712 TI - Frequency-specific attentional modulation in human primary auditory cortex and midbrain. AB - Paying selective attention to an audio frequency selectively enhances activity within primary auditory cortex (PAC) at the tonotopic site (frequency channel) representing that frequency. Animal PAC neurons achieve this 'frequency-specific attentional spotlight' by adapting their frequency tuning, yet comparable evidence in humans is scarce. Moreover, whether the spotlight operates in human midbrain is unknown. To address these issues, we studied the spectral tuning of frequency channels in human PAC and inferior colliculus (IC), using 7-T functional magnetic resonance imaging (FMRI) and frequency mapping, while participants focused on different frequency-specific sounds. We found that shifts in frequency-specific attention alter the response gain, but not tuning profile, of PAC frequency channels. The gain modulation was strongest in low-frequency channels and varied near-monotonically across the tonotopic axis, giving rise to the attentional spotlight. We observed less prominent, non-tonotopic spatial patterns of attentional modulation in IC. These results indicate that the frequency-specific attentional spotlight in human PAC as measured with FMRI arises primarily from tonotopic gain modulation, rather than adapted frequency tuning. Moreover, frequency-specific attentional modulation of afferent sound processing in human IC seems to be considerably weaker, suggesting that the spotlight diminishes toward this lower-order processing stage. Our study sheds light on how the human auditory pathway adapts to the different demands of selective hearing. PMID- 29571711 TI - Curcumin plays neuroprotective roles against traumatic brain injury partly via Nrf2 signaling. AB - Traumatic brain injury (TBI), which leads to high mortality and morbidity, is a prominent public health problem worldwide with no effective treatment. Curcumin has been shown to be beneficial for neuroprotection in vivo and in vitro, but the underlying mechanism remains unclear. This study determined whether the neuroprotective role of curcumin in mouse TBI is dependent on the NF-E2-related factor (Nrf2) pathway. The Feeney weight-drop contusion model was used to mimic TBI. Curcumin was administered intraperitoneally 15 min after TBI induction, and brains were collected at 24 h after TBI. The levels of Nrf2 and its downstream genes (Hmox-1, Nqo1, Gclm, and Gclc) were detected by Western blot and qRT-PCR at 24 h after TBI. In addition, edema, oxidative damage, cell apoptosis and inflammatory reactions were evaluated in wild type (WT) and Nrf2-knockout (Nrf2 KO) mice to explore the role of Nrf2 signaling after curcumin treatment. In wild type mice, curcumin treatment resulted in reduced ipsilateral cortex injury, neutrophil infiltration, and microglia activation, improving neuron survival against TBI-induced apoptosis and degeneration. These effects were accompanied by increased expression and nuclear translocation of Nrf2, and enhanced expression of antioxidant enzymes. However, Nrf2 deletion attenuated the neuroprotective effects of curcumin in Nrf2-KO mice after TBI. These findings demonstrated that curcumin effects on TBI are associated with the activation the Nrf2 pathway, providing novel insights into the neuroprotective role of Nrf2 and the potential therapeutic use of curcumin for TBI. PMID- 29571713 TI - Auditory prediction cues motor preparation in the absence of movements. AB - There is increasing evidence for integrated representation of sensory and motor information in the brain, and that seeing or hearing action-related stimuli may automatically cue the movements required to respond to or produce them. In this study we tested whether anticipation of tones in a known melody automatically activates corresponding motor representations in a predictive way, in preparation for potential upcoming movements. Therefore, we trained 20 non-musicians (8 men, 12 women) to play a simple melody. Then, while they passively listened to the learned or unlearned melodies, we applied single pulse transcranial magnetic stimulation (TMS) over M1 to measure motor evoked potentials from the associated finger muscle either preceding or following the onset of individual tones. Our results show that listening to the learned melody increased corticospinal excitability for specific finger muscles before tone onset. This demonstrates that predictable auditory information can activate motor representations in an anticipatory muscle-specific manner, even in the absence of intention to move. This suggests that the motor system is involved in the prediction of sensory events, likely based on auditory-parietal-prefrontal feedforward/feedback loops that automatically prepare predictable sound-related actions independent of actual execution and the associated auditory feedback. Overall, we propose that multimodal forward models of upcoming sounds and actions support motor preparation, facilitate error detection and correction, and guide perception. PMID- 29571714 TI - The chaotic morphology of the left superior temporal sulcus is genetically constrained. AB - The asymmetry of the superior temporal sulcus (STS) has been identified as a species-specific feature of the human brain. The so-called superior temporal asymmetrical pit (STAP) area is observed from the last trimester of gestation onwards and is far less pronounced in the chimpanzee brain. This asymmetry is associated with more frequent sulcal interruptions, named plis de passage (PPs), leading to the irregular morphology of the left sulcus. In this paper, we aimed to characterize the variability, asymmetry, and heritability of these interruptions in the STS in comparison with the other main sulci. We developed an automated method to extract PPs across the cortex based on a highly reproducible grid of sulcal pits across individuals, which we applied to a subset of Human Connectome Project (HCP) subjects (N = 820). We report that only a few PPs across the cortex are genetically constrained, namely in the collateral, postcentral and superior temporal sulci and the calcarine fissure. Moreover, some PPs occur more often in one hemisphere than the other, namely in the precentral, postcentral, intraparietal sulci, as well as in both inferior and superior temporal sulci. Most importantly, we found that only the interruptions within the STAP region are both asymmetric and genetically constrained. Because this morphological pattern is located in an area of the left hemisphere related to speech, our results suggest structural constraints on the architecture of the linguistic network. PMID- 29571715 TI - 3D conditional generative adversarial networks for high-quality PET image estimation at low dose. AB - Positron emission tomography (PET) is a widely used imaging modality, providing insight into both the biochemical and physiological processes of human body. Usually, a full dose radioactive tracer is required to obtain high-quality PET images for clinical needs. This inevitably raises concerns about potential health hazards. On the other hand, dose reduction may cause the increased noise in the reconstructed PET images, which impacts the image quality to a certain extent. In this paper, in order to reduce the radiation exposure while maintaining the high quality of PET images, we propose a novel method based on 3D conditional generative adversarial networks (3D c-GANs) to estimate the high-quality full dose PET images from low-dose ones. Generative adversarial networks (GANs) include a generator network and a discriminator network which are trained simultaneously with the goal of one beating the other. Similar to GANs, in the proposed 3D c-GANs, we condition the model on an input low-dose PET image and generate a corresponding output full-dose PET image. Specifically, to render the same underlying information between the low-dose and full-dose PET images, a 3D U net-like deep architecture which can combine hierarchical features by using skip connection is designed as the generator network to synthesize the full-dose image. In order to guarantee the synthesized PET image to be close to the real one, we take into account of the estimation error loss in addition to the discriminator feedback to train the generator network. Furthermore, a concatenated 3D c-GANs based progressive refinement scheme is also proposed to further improve the quality of estimated images. Validation was done on a real human brain dataset including both the normal subjects and the subjects diagnosed as mild cognitive impairment (MCI). Experimental results show that our proposed 3D c-GANs method outperforms the benchmark methods and achieves much better performance than the state-of-the-art methods in both qualitative and quantitative measures. PMID- 29571716 TI - Mapping working memory retrieval in space and in time: A combined electroencephalography and electrocorticography approach. AB - In this study, we investigated the time course and neural correlates of the retrieval process underlying visual working memory. We made use of a rare dataset in which the same task was recorded using both scalp electroencephalography (EEG) and Electrocorticography (ECoG), respectively. This allowed us to examine with great spatial and temporal detail how the retrieval process works, and in particular how the medial temporal lobe (MTL) is involved. In each trial, participants judged whether a probe face had been among a set of recently studied faces. With a method that combines hidden semi-Markov models and multivariate pattern analysis, the neural signal was decomposed into a sequence of latent cognitive stages with information about their durations on a trial-by-trial basis. Analyzed separately, EEG and ECoG data yielded converging results on discovered stages and their interpretation, which reflected 1) a brief pre attention stage, 2) encoding the stimulus, 3) retrieving the studied set, and 4) making a decision. Combining these stages with the high spatial resolution of ECoG suggested that activity in the temporal cortex reflected item familiarity in the retrieval stage; and that once retrieval is complete, there is active maintenance of the studied face set in the decision stage in the MTL. During this same period, the frontal cortex guides the decision by means of theta coupling with the MTL. These observations generalize previous findings on the role of MTL theta from long-term memory tasks to short-term memory tasks. PMID- 29571717 TI - Simultaneous scalp recorded EEG and local field potentials from monkey ventral premotor cortex during action observation and execution reveals the contribution of mirror and motor neurons to the mu-rhythm. AB - The desynchronization of alpha and beta oscillations (mu rhythm) in the central scalp EEG during action observation and action execution is thought to reflect neural mirroring processes. However, the extent to which mirror neurons (MNs) or other populations of neurons contribute to such EEG desynchronization is still unknown. Here, we provide the first evidence that, in the monkey, the neuronal activity recorded from the ventral premotor cortex (PMv) strongly contributes to the EEG changes occurring in the beta band over central scalp electrodes, during executed and observed actions. We simultaneously recorded scalp EEG and extracellular activity, Multi Unit Activity (MUA) and Local Field Potentials (LFP), from area F5 of two macaques executing and observing grasping actions. We found that MUA highly correlates with an increase in high gamma LFP power and, interestingly, such LFP power increase also correlates to EEG beta - and in part also to alpha - desynchronization. In terms of timing of signal changes, the increase in high gamma LFP power precedes the EEG desynchronization, during both action observation and execution, thus suggesting a causal role of PMv neuronal activity in the modulation of the alpha and beta mu-rhythm. Lastly, neuronal signals from deeper layers of PMv exert a greater contribution than superficial layers to the EEG beta rhythm modulation, especially during the motor task. Our findings have clear implications for EEG studies in that they demonstrate that the activity of different populations of neurons in PMv contribute to the generation of the mu-rhythm.

AB - BACKGROUND: Scalds are the most common cause of burns in children, yet there is little information available about the inflammatory response. The aim of the study was to investigate the response to treatment with antibiotics among scalded children by following the C-reactive protein (CRP) concentration, procalcitonin (PCT) concentration, and white blood cell count (WCC) during the first two weeks after injury. METHODS: All children with scalds who presented to the Burn Centre during 2010-2016 were included in this retrospective study. All measurements of CRP, PCT, and WCC from the first 14days after injury were recorded, and each patient's maximum values during days 0-2, 3-7, and 8-14 were used for calculations. Multivariable regression for panel data was used to study the inflammatory response after antibiotic treatment. RESULTS: A total of 216 children were included. C-reactive protein was 45mg/L (p<0.001) higher in the group treated with antibiotics, and decreased with 8.8mg/L per day over the studied time in this group, which was more than twice as fast as among the children who were not given antibiotics. CONCLUSION: The CRP response, among children with minor scalds treated with antibiotics, shows an appreciable rise during the first week of injury that subsided rapidly during the second week.

AB - Modafinil is a psychostimulant drug prescribed for treatment of narcolepsy. However, it is used as a "smart drug" especially by young adults to increase wakefulness, concentration and mental performance. Therefore, it can also be used by women with childbearing potential and its developmental effects can become a concern. The aim of this study was to assess behavioural and immune effects of prenatal modafinil exposure in mice and to evaluate the reaction to methamphetamine exposure on these animals in adult age. Pregnant female mice were given either saline or modafinil (50 mg/kg orally) from gestation day (GD) 3 to GD 10 and then a challenge dose on GD 17. The male offspring were treated analogously at the age of 10 weeks with methamphetamine (2.5 mg/kg orally). Changes in the spontaneous locomotor/exploratory behaviour and anxiogenic profile in the open field test were assessed in naive animals, after an acute and 8th modafinil dose and the challenge dose following a 7-day wash-out period. One month after completion of the behavioural study, the leukocyte phagocytosis was examined by zymosan induced and luminol-aided chemiluminiscence assay in vitro. The modafinil prenatally exposed mice showed basal hypolocomotion, increased anxiety, lower locomotor effect of acute methamphetamine and increased vulnerability to behavioural sensitization. The leukocyte activity did not show significant differences. Prenatal modafinil exposure alters basal behavioural profile, decreases acute effect of methamphetamine and enhances vulnerability to development of behavioural sensitization at adulthood. This may lead to higher vulnerability to development of addiction. PMID- 29571721 TI - Relation of Platelet Indexes to Platelet Reactivity and Periprocedural Myocardial Infarction in Patients Who Underwent Percutaneous Coronary Angioplasty. AB - No comprehensive data are available on the role of platelet indexes (PI) in the periprocedural risk stratification of patients who underwent percutaneous coronary intervention (PCI). The aim of this study was to investigate the relation of PI to platelet reactivity (PR) and periprocedural myocardial infarction (PMI) in patients receiving PCI. A total of 502 PCI patients had preprocedural measurement of PI and PR, the latter assessed by VerifyNow P2Y12 assay. Study end points were incidence of PMI and high platelet reactivity (HPR) according to tertiles of PI and evaluation of PI in HPR patients. Incidence of PMI in the overall population was 6.6%. Rates of PMI were not different in PI tertiles: platelet count (I: 6.0%, II: 7.1%, III: 6.5%; p = 0.74), mean platelet volume (MPV, I: 6.6%, II: 7.3%, III: 5.8%;p = 0.86), platelet distribution width (I: 7.2%, II: 7.2%, III: 5.8%;p = 0.74), and MPV/P ratio (I: 6.6%, II: 6.0%, III: 7.1%; p = 0.91). The occurrence of PMI was significantly different in PR tertiles (I: 3%, II: 5.4%, III: 11.4%; p = 0.006). Platelet count and MPV/P ratio were significantly different in patients with and without HPR (221.8 +/- 58.6 * 103/uL vs207 +/- 59.4 * 103/uL, p = 0.008; 51.73 +/- 15.17 vs 56.7 +/- 18.3, p = 0.002).In conclusion, this study showed no relation between PI and PMI in PCI patients but confirms the association of HPR with increased incidence of PMI; thus, PI seem to be not able to identify patients at higher periprocedural risk, but monitoring PR by a bedside assay remains a useful tool for risk stratification. PMID- 29571722 TI - Stroke and Cardiovascular Events After Ablation or Antiarrhythmic Drugs for Treatment of Patients With Atrial Fibrillation. AB - Catheter ablation and antiarrhythmic drugs (AADs) are the most common rhythm control strategies for atrial fibrillation (AF). Data comparing the rate of stroke and cardiovascular events between the treatment strategies are limited. Therefore, this observational study uses claims data to compare rate of cardiovascular hospitalization and stroke for patients with AF treated with ablation or AADs. Patients in the MarketScan dataset with AF between January 2010 and December 2014 were categorized in the ablation group if an atrial catheter ablation was performed, or in the AAD group if a relevant AAD was prescribed for AF but no ablation was performed. One year of history was required, and the index event was selected as the most recent ablation or AAD prescription closest to January 1, 2013. A 2:1 propensity score match was performed for age, gender, co morbidities, and total medical cost in the year before index event. Outcomes included thromboembolic event (ischemic stroke, transient ischemic attack, or systemic embolism) and all cardiovascular hospitalizations. Of the 164,639 patients in the AAD group, 29,456 were matched to the 14,728 ablation patients. There were no significant differences in age (64 +/- 10 in both groups), gender (58% male), or CHA2DS2-VASc score (3.2 +/- 1.3). Risk of hospitalization with primary diagnosis of thromboembolic event was 41% greater in the AADs group (p < 0.001), and cardiovascular hospitalizations were 13% more likely (p < 0.001). In conclusion, patients treated with catheter ablation of AF have lower risk of thromboembolic events and cardiovascular hospitalizations than a matched cohort of patients managed with AADs. PMID- 29571723 TI - Phytochemical profiling and antiviral activity of Ajuga bracteosa, Ajuga parviflora, Berberis lycium and Citrus lemon against Hepatitis C Virus. AB - Hepatitis C is a serious health issue and cause liver disorders in millions of people. Available therapeutic agents require long term administration with numerous side effects. Therefore, there is a dire need to find alternative treatment options for this disease. Since ancient times, medicinal plants are widely used to cure various diseases with no or less harmful effects. Therefore, this study was designed to find out phytochemicals and investigate antiviral activity of methanol extract of Ajuga bracteosa, Ajuga parviflora, Berberis lycium and Citrus lemon against Hepatitis C Virus (HCV infection). Phytochemical analysis of the plant extract was performed using various chemical tests. Toxicity of the plant extract was determined against using trypan blue exclusion method. Antiviral activity of the selected plant extract was find out against HCV infected HepG2 cells. For this purpose, HepG2 cells were seeded with HCV positive and negative serum and nontoxic doses of plant extract for 24 and 48 h. After this RNA was extracted and viral load was determined using Real-time PCR. Phytochemical analysis showed the presence of flavonoids and phenols in all plant extracts while amino acids, alkaloids and tannins were present in B. lycium and saponins were detected in C. lemon. Toxicity assay showed that all plant extracts were nontoxic at maximum concentration of 200 MUg/ml except B. lycium, which showed mild toxicity at 40 MUg/ml and were extremely toxic at 60 MUg/ml and above doses. Real-time PCR quantitation result revealed that after 24 h treatments A. parviflora showed highest antiviral activity, followed by A. bracteosa, while B. lycium extract had low (35%) and C. lemon has no antiviral effects. The 48 h treatments showed an increase antiviral activity by A. bracteosa followed by A. parviflora and B. lycium while C. lemon showed negative effect. Our results depicted that mentioned plants might be used as an alternative therapeutic regime or in combination with existing treatments against HCV. PMID- 29571724 TI - Puerarin prevents LPS-induced acute lung injury via inhibiting inflammatory response. AB - Acute lung injury (ALI) is a critical illness syndrome with high morbidity and mortality in patients. Inflammation has been known to be involved in the development of ALI. The purpose of this study was to investigate the effect of puerarin on lipopolysaccharide (LPS)-induced ALI in mice. The pro-inflammatory cytokines TNF-alpha, IL-6 and IL-1beta were determined by ELISA. Western blot analysis was used for detecting the expression of NF-kappaB, IkappaBalpha, and LXRalpha. And myeloperoxidase (MPO) activity, lung wet/dry (W/D) ratio, and histopathological examination were also detected in lung tissues. The results showed that puerarin significantly inhibited LPS-stimulated MPO activity in lung tissues. Meanwhile, puerarin attenuated lung histopathological changes and lung wet/dry (W/D) ratio. We also found that the expression of pro-inflammatory cytokines, TNF-alpha, IL-6 and IL-1beta were inhibited by puerarin. Puerarin also inhibited LPS-induced TNF-alpha in RAW264.7 cells and IL-8 in A549 cells. From the results of western blotting, puerarin significantly suppressed LPS-stimulated NF-kappaB activation. And the expression of LXRalpha was dose-dependently increased by treatment of puerarin. The inhibition of puerarin on TNF-alpha production in RAW264.7 cells and IL-8 production in A549 cells were blocked by LXRalpha inhibitor geranylgeranyl pyrophosphate (GGPP). These results suggested that puerarin attenuated ALI by activating LXRalpha, which subsequently inhibited LPS-induced inflammatory response.

PMID- 29571725 TI - Attenuation of quorum sensing regulated virulence and biofilm development in Pseudomonas aeruginosa PAO1 by Diaporthe phaseolorum SSP12. AB - In recent years, Pseudomonas aeruginosa PAO1 emerged as the significant pathogenic microorganism in majority of the hospital-acquired infections due to its resistance to the conventional antibiotics by virtue of its highly organized quorum sensing and associated biofilm formation. In the present study, quorum sensing attenuation potential of Diaporthe phaseolorum SSP12 extract was investigated against P. aeruginosa PAO1 amply supported by molecular docking studies. D. phaseolorum SSP12 extract significantly inhibited the production of LasI/R mediated LasA protease, LasB elastase and chitinase with 66.52 +/- 5.41, 71.26 +/- 4.58 and 61.16 +/- 4.28% of inhibition respectively at a concentration of 750 MUg mL-1. In addition, RhlI/R mediated production of pyocyanin, exopolysaccharides and rhamnolipids were also down-regulated by 74.71 +/- 3.97, 66.41 +/- 3.62 and 63.75 +/- 3.76% respectively on treatment with sub-MIC concentration of D. phaseolorum SSP12. The light, fluorescence and confocal laser scanning microscopic (CLSM) analysis confirmed the significant disruption in biofilm formation. The presence of bioactive constituents such as phenyl ethylalcohol, 2, 4-di-tert-butylphenol, fenaclon, 1, 4-phenylenediacetic acid, and benzyl hydrazine in D. phaseolorum SSP12 extract was evident from Gas chromatography-mass spectrophotometric (GC-MS) analysis. From the in silico molecular docking studies, fenaclon and 2, 4-di-tert-butylphenol competitively binds to QS receptors LasR and RhlR and alters the binding of its cognate ligands and modulates the expression of virulence phenotypes. The promising anti quorum sensing efficacy of D. phaseolorum SSP12 extract suggested new avenues for development of anti-infective drugs from fungal derived metabolites to counteract the problems associated with conventional antibiotic therapies.

AB - BACKGROUND: Hybrid coronary revascularization (HCR) is an evolving coronary revascularization strategy for the treatment of multivessel coronary artery disease. We provide a comparative analysis to conventional on-pump coronary artery bypass graft surgery (CABG) with long-term follow-up. METHODS: We included all double on-pump CABG (n = 682) and HCR (147 robotic-assisted minimally invasive bypass grafts of the left internal thoracic artery to the left anterior descending coronary artery and percutaneous coronary intervention to one of the non-left anterior descending coronary artery vessels) performed in our institution between March 2004 and November 2015. We performed an adjusted analysis using inverse-probability weighting based on the propensity score of receiving either on-pump CABG or HCR. RESULTS: In the adjusted analysis, there was no statistically significant difference in the incidence of reexploration for bleeding, perioperative myocardial infarction, stroke, need for hemodialysis, blood transfusion rate, prolonged mechanical ventilation, and intensive care unit length of stay. Hybrid coronary revascularization was associated with lower inhospital mortality (CABG 1.3%, HCR 0%, p = 0.008), and shorter mean (+/- SD) hospital length of stay (CABG 6.7 +/- 4.7 days, HCR 4.5 +/- 2.1 days, p < 0.001). After a median follow-up period of 70 months (range, 37 to 106) for the CABG group and 96 months (range, 53 to 114) for the HCR group, there was no significant difference in survival (CABG 92%, HCR 97%, p = 0.13) or freedom from any form of revascularization (CABG 93%, HCR 91%, p = 0.27). Hybrid coronary revascularization was superior in freedom from angina (CABG 70%, HCR 91%, p < 0.001). CONCLUSIONS: For selected patients, HCR is associated with a faster postoperative recovery as well as similar short-term and long-term outcomes when compared with standard on-pump CABG. PMID- 29571731 TI - HMGB1 mediates HAdV-7 infection-induced pulmonary inflammation in mice. AB - Human adenovirus (HAdV) is a common respiratory pathogen in children, with no safe and effective treatment currently available. HAdV type 7 (HAdV-7), in particular, causes severe pediatric pneumonia with a high incidence of sequelae and mortality. Clinical data and animal experiments suggest that HAdV-7-induced pneumonia promotes cell necrosis, releasing a large number of inflammatory mediators. In recent years, the high mobility group box-1 (HMGB1) protein, released by necrotic cells, has been shown to play important roles in several viral infections. Here, we show that HMGB1 levels gradually increased in the media supernatants of HAdV-7 infected A549 cells, starting at 12 h post infection. In vivo, HMGB1 levels in BALF and mRNA levels in lung tissues significantly increased after 3 days of HAdV-7 infection. Among the HMGB1 receptor genes, TLR-4 and TLR-9 expression increased, and so did the receptor for advanced glycation end-products (RAGE). Interestingly, NF-kappaB levels also increased concomitantly. Conversely, when HMGB1 was blocked, the pathological scores from lung tissues, inflammatory mediator levels, and viral copy number all were reduced significantly; in addition, HMGB1-related signaling pathway molecules, namely TLR-4, TLR-9, RAGE, and NF-kappaB were also reduced. We conclude that HMGB1 promotes HAdV-7 replication and signals through TLR-4, TLR-9, and RAGE receptors to activate NF-kappaB, stimulating the release of inflammatory mediators and contributing to adenoviral pathology. Thus, HMGB1 could be used as a therapeutic target in HAdV-7 infection. PMID- 29571732 TI - Induction of MEK/ERK activity by AZD8055 confers acquired resistance in neuroblastoma. AB - Mammalian target of rapamycin (mTOR) complex (mTORC) is frequently activated in diverse cancers. Although dual mTORC1/2 inhibitors are currently under development to treat various malignancies, the emergence of drug resistance has proven to be a major complication. AZD8055 is a novel, potent ATP-competitive and specific inhibitor of mTOR kinase activity, which blocks both mTORC1 and mTORC2 activation. In this study, we acquired AZD8055-resistant neuroblastoma (NB) cell sublines by using prolonged stepwise escalation of AZD8055 exposure (4-12 weeks). Here we demonstrate that the AZD8055-resistant sublines (TGW-R and SMS-KAN-R) exhibited marked resistance to AZD8055 compared to the parent cells (TGW and SMS KAN). The cell cycle G1/S transition was advanced in resistant cells. In addition, the resistance against AZD8055 correlated with over-activation of MEK/ERK signaling pathway. Furthermore, combination of AZD8055 and MEK inhibitor U0126 enhanced the growth inhibition of resistant cells significantly in vitro and in vivo. In conclusion, these data show that targeting mTOR kinase and MEK/ERK signaling simultaneously might help to overcome AZD8055 resistance in NB. PMID- 29571733 TI - The guanine nucleotide-binding protein alpha subunit protein ChGnaq positively regulates Hsc70 transcription in Crassostrea hongkongensis. AB - Gnaq, one of Guanine nucleotide-binding protein alpha subunits, was isolated from cellular nucleus extracts of oyster Crassostrea hongkongensis gills with biotin labeled ChHsc70 promoter by means of DNA-affinity purification, and preliminarily identified with mass spectrometry analysis. ChGnaq mRNA depletion by RNAi technique led to clear reduction in ChHsc70 mRNA expression of C. hongkongensis hemocytes. Correspondently, ChGnaq over-expression in heterologous HEK293T cells correlated with elevated expression activation of ChHsc70 promoter. Quantitative real time PCR analysis showed that both ChHsc70 and ChGnaq transcriptions were responsive to external physical/chemical stresses by heat, CdCl2 and NP. This suggested a plausible association between ChHsc70 and ChGnaq in the stress induced genetic regulatory pathway. This study discovered a positively regulatory role of ChGnaq in controlling ChHsc70 transcription of C. hongkongensis, and conduced to a better understanding of the regulatory mechanisms in control of Hsc70 transcription. PMID- 29571734 TI - NLRP1 deficiency attenuates diabetic retinopathy (DR) in mice through suppressing inflammation response. AB - Diabetic retinopathy (DR) is the common cause of diabetic vascular complications. The NOD-like receptor (NLR) family, pyrin domain containing 1 (NLRP1), also known as NALP1, inflammasome is the first member of the NLR family to be discovered, playing an important role in inflammatory response. However, its effect on DR development has not been reported. In the study, the wild type (WT) and NLRP1-/- mice were injected with streptozotocin (STZ) to induce DR. The results indicated that NLRP1-/- significantly increased bodyweight reduction and decreased blood glucose levels induced by STZ. WT/DR mice exhibited higher levels of NLRP1 in retinas. NLRP1-/- ameliorated retinal abnormalities in DR mice using H&E staining. In addition, attenuated avascular areas and neovascular tufts were also observed in NLRP1-/-/DR mice. The levels of pro-inflammatory cytokines in serum and retinas were highly induced in WT/DR mice, whereas being markedly reduced by NLRP1-/-. In addition, vascular endothelial growth factor (VEGF) and Iba1 expressions induced by STZ in serum or retinas were significantly down-regulated in NLRP1-/-/DR mice. Consistently, NLRP1-/- attenuated ASC and Caspase-1 expressions in retinas of DR mice. Compared to WT/DR group, NLRP1-/- markedly decreased retina p-nuclear factor-kappaB (NF-kappaB), interleukin-1beta (IL 1beta) and IL-18 levels. And similar results were confirmed in vitro that suppressing NLRP1/ASC inflammasome ameliorated inflammatory response in fructose treated retinal ganglion cells. The results above indicated that the modulation of NLRP1 inflammasome might be a promising strategy for DR therapy. PMID- 29571735 TI - Regional up-regulation of NOX2 contributes to the differential vulnerability of outer hair cells to neomycin. AB - In hearing loss induced by aminoglycoside antibiotics, the outer hair cells (OHCs) in the basal turn are always more susceptible than OHCs in the apical turn, while the underlying mechanisms remain unknown. In this study, we reported that NAPDH oxidase 2 (NOX2) played an important role in the OHCs damage preferentially in the basal turn. Normally, NOX2 was evenly expressed in OHCs among different turns, at a relatively low level. However, after neomycin treatment, NOX2 was dominantly induced in OHCs in the basal turn. In vivo and in vitro studies demonstrated that inhibition of NOX2 significantly alleviated neomycin-induced OHCs damages, as seen from both the cleaved caspase-3 and TUNEL staining. Moreover, gp91 ds-tat delivery and DHE staining results showed that NOX2-derived ROS was responsible for neomycin ototoxicity. Taken together, our study shows that regional up-expression of NOX2 and subsequent increase of ROS in OHCs of the basal turn is an important factor contributing to the vulnerability of OHCs there, which should shed light on the prevention of hearing loss induced by aminoglycoside antibiotics. PMID- 29571736 TI - Liraglutide attenuates NLRP3 inflammasome-dependent pyroptosis via regulating SIRT1/NOX4/ROS pathway in H9c2 cells. AB - The glucagon-like peptide-1 analog liraglutide has been proved to exert cardioprotective role via activating prosurvival pathways and suppressing inflammation. The activation of NLRP3 inflammasome plays an important role in ischemic injury. The effect of liraglutide on NLRP3 inflammasome-dependent pyroptosis remains unclear. In this study, we established a double stimulation model with TNF-alpha and hypoxia to mimic ischemic environment and to induce NLRP3 inflammasome activation in H9c2 cardiomyoblasts. Pretreatment with 100 nM liraglutide could efficiently inhibit TNF-alpha and hypoxia-induced inflammasome activation, as evidenced by the decreased expression of NLRP3, caspase-1 p20 and Gasdermin D N-terminal fragment. Meanwhile, the pyroptosis was also demonstrated to be suppressed, indicated by the increased cell viability and decreased lactate dehydrogenase release in the cells. Mechanistically, liraglutide reversed the level of SIRT1 and the selective SIRT1 inhibitor EX 527 significantly abolished the anti-pyroptosis role of liraglutide. Furthermore, liraglutide diminished the levels of ROS generation and NOX4 expression, which could also be blocked by EX 527. Our results uncovered the anti-pyroptosis role of liraglutide in TNF-alpha and hypoxia-stimulated H9c2 cells, which was associated with SIRT1/NOX4/ROS pathway. PMID- 29571737 TI - Characterization of a non-phosphotransferase system for cis,cis-muconic acid production in Corynebacterium glutamicum. AB - Cis,cis-muconic acid (CCM) is a biochemical material that can be used for the production of various plastics and polymers and is particularly gaining attention as an adipic acid precursor for the synthesis of nylon-6,6. In the current study, the production of CCM was first attempted by introducing a newly developed protocatechuate (PCA) decarboxylase from Corynebacterium glutamicum 13032 to inha103, which completed the biosynthetic pathway therein. To improve CCM productivity, a phosphoenol pyruvate (PEP)-dependent phosphotransferase system (PTS) that consumed the existing glucose was developed, in the form of a strain with a non-PTS that did not consume PEP. To improve glucose uptake, we developed P25 strain, in which iolR (a transcriptional regulator gene) was additionally deleted. Strain P28, a P25 derivative expressing PCA decarboxylase, produced 4.01 g/L of CCM, which was 14% more than that produced by the parental strain. Moreover, strains P29 and P30, with an active pentose phosphate pathway and overexpressing important genes (qsuB) in the metabolic pathway, produced 4.36 and 4.5 g/L of CCM, respectively. Particularly, the yield per glucose in strain P30 was similar to that of the fed-batch culture of Escherichia coli, which has the highest reported yield of 22% (mol/mol). These results are underpinned by the characteristics of the non-PTS with increased PEP availability and a strain with deletion of the iolR gene, which greatly increased glucose uptake. PMID- 29571738 TI - Determination of Interaction Parameters for Reversibly Self-Associating Antibodies: A Comparative Analysis. AB - Monoclonal antibodies (mAbs) represent a major class of biotherapeutics and are the fastest growing category of biologic drugs on the market. However, mAb development and formulation are often impeded by reversible self-association (RSA), defined as the dynamic exchange of monomers with native-state oligomers. Here, we present a comparative analysis of the self-association properties for 5 IgG mAbs, under matched conditions and using orthogonal methods. Concentration dependent dynamic light scattering and sedimentation velocity studies revealed that the majority of mAbs examined exhibited weak to moderate RSA. However, because these studies were carried out at mAb concentrations in the mg/mL range, we also observed significant nonideality. Noting that nonideality frequently masks RSA and vice versa, we conducted direct boundary fitting of the sedimentation velocity data to determine stoichiometric binding models, interaction affinities, and nonideality terms for each mAb. These analyses revealed equilibrium constants from micromolar to millimolar and stoichiometric models from monomer-dimer to isodesmic. Moreover, even for those mAbs described by identical models, we observed distinct kinetics of self-association. The accuracy of the models and their corresponding equilibrium constants were addressed using sedimentation equilibrium and simulations. Overall, these results serve as the starting point for the comparative dissection of RSA mechanisms in therapeutic mAbs. PMID- 29571739 TI - Translational Pharmacokinetic/Pharmacodynamic Characterization and Target Mediated Drug Disposition Modeling of an Anti-Tissue Factor Pathway Inhibitor Antibody, PF-06741086. AB - Tissue factor pathway inhibitor (TFPI) exhibits multiple isoforms, which are known to present in multiple locations such as plasma, endothelium, and platelets. TFPI is an endogenous negative modulator of the coagulation pathway, and therefore, neutralization of TFPI function can potentially increase coagulation activity. A human monoclonal antibody, PF-06741086, which interacts with all isoforms of TFPI is currently being tested in clinic for treating hemophilia patients with and without inhibitors. To support clinical development of PF-06741086, pharmacokinetics (PK) and pharmacodynamics of PF-06741086 were characterized in monkeys. In addition, a mechanistic model approach was used to estimate PK parameters in monkeys and simulate PK profiles in human. The results show that PF-06741086 exhibited target-mediated drug disposition and had specific effects on various hemostatic markers including diluted prothrombin time, thrombin generation, and thrombin-antithrombin complex in monkeys after administration. The model-predicted and observed human exposures were compared retrospectively, and the result indicates that the exposure prediction was reasonable within less than 2-fold deviation. This study demonstrated in vivo efficacy of PF-06741086 in monkeys and the utility of a rational mechanistic approach to describe PK for a monoclonal antibody with complex target binding. PMID- 29571740 TI - Biowaiver Monographs for Immediate Release Solid Oral Dosage Forms: Proguanil Hydrochloride. AB - Literature data relevant to the decision to waive in vivo bioequivalence testing for the approval of generic immediate release solid oral dosage forms of proguanil hydrochloride are reviewed. To elucidate the Biopharmaceutics Classification System (BCS) classification, experimental solubility and dissolution studies were also carried out. The antimalarial proguanil hydrochloride, effective via the parent compound proguanil and the metabolite cycloguanil, is not considered to be a narrow therapeutic index drug. Proguanil hydrochloride salt was shown to be highly soluble according to the U.S. Food and Drug Administration, World Health Organization, and European Medicines Agency guidelines, but data for permeability are inconclusive. Therefore, proguanil hydrochloride is conservatively classified as a BCS class 3 substance. In view of this information and the assessment of risks associated with a false positive decision, a BCS-based biowaiver approval procedure can be recommended for orally administered solid immediate release products containing proguanil hydrochloride, provided well-known excipients are used in usual amounts and provided the in vitro dissolution of the test and reference products is very rapid (85% or more are dissolved in 15 min at pH 1.2, 4.5, and 6.8) and is performed according to the current requirements for BCS-based biowaivers. PMID- 29571741 TI - Immunobiologically relevant level of aflatoxin B1 alters transcription of key functional immune genes, phagocytosis and survival of human dendritic cells. AB - The effects of naturally occurring levels of aflatoxin (AF) B1 on the expression of key molecules and function of dendritic cells (DCs) were investigated on human monocyte-derived DCs (MDDCs) by cell culture, RT-qPCR, and flow cytometry. An environmentally relevant level of AFB1 remarkably impaired the phagocytic capacity of MDDCs. Furthermore, AFB1 significantly affected the transcript levels of some key functional genes in MDDCs. It caused an up-regulation of key transcripts in cytochrome P450 (CYP) family, MyD88, NF-KB, TNF-alpha, TLR2, TLR4, COX-2, HLA-DR, CCR7, CD209, LFA3 and CD16. AFB1 down-regulated the expression of AhR, TGF-beta, CD11c and CD64 within 2-12 h post-exposure. In contrast, the transcription of some other key genes, including IL-10, IL-1beta, AKR7A2, GSTM1, IL-6. IL-8 and C5aR in post-AFB1 treated MDDCs was only slightly changed. The results indicate that an environmentally relevant level of AFB1 impairs the phagocytosis capacity of MDDCs and dysregulates the key functions in these pivotal immune cells. This could provide a mechanistic explanation for the observed in vivo immunotoxicity associated with this mycotoxin, and further emphasize the essential need for reduction of AFB1 levels in agricultural commodities. PMID- 29571742 TI - Family Interview to Enable Donation of Organs for Transplantation: Evidence-based Practice. AB - BACKGROUND: In this study we propose a theoretical and practical basis for the best practices for interviewing relatives of brain-dead eligible organ donors. METHODS: This investigation was a reflective study of the methodologic factors of the family interview that affect their decision regarding the donation of a deceased patient's organs for transplantation. The articles that formed the empirical basis of the trial were obtained from PubMed, which is a free-access tool of the MEDLINE database of the United States National Library of Medicine. Published articles that allowed us to reflect on evidence-based family interview practice were selected. RESULTS: Thirty-six scientific articles were used to guide our assessment the family interview, providing evidence for its adequate execution in view of the following prerequisites: When should the family interview be performed? Where should it be done? How many and which people should participate in the interview? Who should perform it? How should it be done? CONCLUSION: Scientific studies offer evidence to donation and transplantation specialists that can help them in their daily work regarding their interactions with relatives in the process of decisionmaking and family consent. PMID- 29571743 TI - Acute Inflammatory Syndrome Paradoxically Induced by De Novo Purine Inhibitors Synthesis Before Renal Transplantation: A Case Report and Review of the Literature. AB - BACKGROUND: Mycophenolate mofetil (MMF) and mizoribine (MZR) are increasingly used as immunosuppressive agents for organ transplantation and chronic inflammation. We report a patient with rheumatoid arthritis who had an acute inflammatory syndrome triggered by preoperative immunosuppression therapy with both MMF and MZR. CASE REPORT: A 41-year-old woman with IgA nephropathy was referred to our department for living donor renal transplantation. She had rheumatoid arthritis that was adequately treated with prednisolone 5 mg once a day and salazosulfapyridine 2000 mg once a day. MMF 1000 mg twice a day was started for desensitization therapy. Three days later, the patient developed arthritis in the joints of her left hand and elevated inflammatory markers. On day 7, MMF was switched to MZR 150 mg 3 times a day. However, the symptoms extended to both shoulders and the joints of the right foot; MZR was discontinued. The arthritis and inflammatory markers improved. Two months later, the patient was rechallenged with MMF followed by MZR, resulting in a similar clinical course as previously. Tacrolimus (TAC) 3 mg twice a day and everolimus (EVL) 0.5 mg twice a day were introduced as alternative immunosuppressant therapies. No arthritis occurred. ABO-compatible living donor renal transplantation was successfully performed. The patient received TAC, EVL, prednisolone, rituximab, and basiliximab, and her postoperative course was uneventful without arthritis or rejection. At 9 months postoperatively, the serum creatinine was 0.79 mg/dL. CONCLUSIONS: Acute inflammatory syndrome is an extremely rare complication triggered by preoperative immunosuppression therapy. If antimetabolites cannot be used in immunologically high-risk patients, transplantation becomes very difficult. Clinicians should keep in mind this paradoxical reaction. PMID- 29571744 TI - The NC domain of HIV-1 Gag contributes to the interaction of Gag with TSG101. AB - BACKGROUND: HIV-1 Gag polyprotein orchestrates the assembly of viral particles. Its C-terminus consists of the nucleocapsid (NC) domain that interacts with RNA, and the p6 domain containing the PTAP motif that binds the cellular ESCRT factor TSG101 and ALIX. Deletion of the NC domain of Gag (GagNC) results in defective Gag assembly, a decrease in virus production and, thus probably affects recruitment of the ESCRT machinery. To investigate the role of GagNC in this recruitment, we analysed its impact on TSG101 and ALIX localisations and interactions in cells expressing Gag. METHODS: Cells expressing mCherry-Gag or derivatives, alone or together with eGFP-TSG101 or eGFP-ALIX, were analysed by confocal microscopy and FLIM-FRET. Chemical shift mapping between TSG101-UEV motif and Gag C-terminus was performed by NMR. RESULTS: We show that deletion of NC or of its two zinc fingers decreases the amount of Gag-TSG101 interacting complexes in cells. These findings are supported by NMR data showing chemical shift perturbations in the NC domain in- and outside - of the zinc finger elements upon TSG101 binding. The NMR data further identify a large stretch of amino acids within the p6 domain directly interacting with TSG101. CONCLUSION: The NC zinc fingers and p6 domain of Gag participate in the formation of the Gag TSG101 complex and in its cellular localisation. GENERAL SIGNIFICANCE: This study illustrates that the NC and p6 domains cooperate in the interaction with TSG101 during HIV-1 budding. In addition, details on the Gag-TSG101 complex were obtained by combining two high resolution biophysical techniques. PMID- 29571745 TI - Differential effects on enzyme stability and kinetic parameters of mutants related to human triosephosphate isomerase deficiency. AB - Human triosephosphate isomerase (TIM) deficiency is a very rare disease, but there are several mutations reported to be causing the illness. In this work, we produced nine recombinant human triosephosphate isomerases which have the mutations reported to produce TIM deficiency. These enzymes were characterized biophysically and biochemically to determine their kinetic and stability parameters, and also to substitute TIM activity in supporting the growth of an Escherichia coli strain lacking the tim gene. Our results allowed us to rate the deleteriousness of the human TIM mutants based on the type and severity of the alterations observed, to classify four "unknown severity mutants" with altered residues in positions 62, 72, 122 and 154 and to explain in structural terms the mutation V231M, the most affected mutant from the kinetic point of view and the only homozygous mutation reported besides E104D. PMID- 29571746 TI - Oleuropein aglycone: A polyphenol with different targets against amyloid toxicity. AB - BACKGROUND: Many data highlight the benefits of the Mediterranean diet and its main lipid component, extra-virgin olive oil (EVOO). EVOO contains many phenolic compounds that have been found effective against several aging- and lifestyle related diseases, including neurodegeneration. Oleuropein, a phenolic secoiroid glycoside, is the main polyphenol in the olive oil. It has been reported that the aglycone form of Oleuropein (OleA) interferes in vitro and in vivo with amyloid aggregation of a number of proteins/peptides involved in amyloid, particularly neurodegenerative, diseases avoiding the growth of toxic oligomers and displaying protection against cognitive deterioration. METHODS: In this study, we carried out a cellular and biophysical study on the relationships between the effects of OleA on the aggregation and cell interactions of the D76N beta2-microglobulin (D76N b2m) variant associated with a familial form of systemic amyloidosis with progressive bowel dysfunction and extensive visceral amyloid deposits. RESULTS: Our results indicate that OleA protection against D76N b2m cytotoxicity results from i) a modification of the conformational and biophysical properties of its amyloid fibrils; ii) a modification of the cell bilayer surface properties of exposed cells. CONCLUSIONS: This study reveals that OleA remodels not only D76N b2m aggregates but also the cell membrane interfering with the misfolded proteins cell membrane association, in most cases an early event triggering amyloid mediated cytotoxicity. GENERAL SIGNIFICANCE: The data provided in the present article focus on OleA protection, featuring this polyphenol as a promising plant molecule useful against amyloid diseases. PMID- 29571748 TI - Structural basis of the signal transduction via transmembrane domain of the human growth hormone receptor. AB - BACKGROUND: Prior studies of the human growth hormone receptor (GHR) revealed a distinct role of spatial rearrangements of its dimeric transmembrane domain in signal transduction across membrane. Detailed structural information obtained in the present study allowed elucidating the bases of such rearrangement and provided novel insights into receptor functioning. METHODS: We investigated the dimerization of recombinant TMD fragment GHR254-294 by means of high-resolution NMR in DPC micelles and molecular dynamics in explicit POPC membrane. RESULTS: We resolved two distinct dimeric structures of GHR TMD coexisting in membrane mimicking micellar environment and providing left- and right-handed helix-helix association via different dimerization motifs. Based on the available mutagenesis data, the conformations correspond to the dormant and active receptor states and are distinguished by cis-trans isomerization of Phe-Pro266 bond in the transmembrane helix entry. Molecular dynamic relaxations of the structures in lipid bilayer revealed the role of the proline residue in functionally significant rearrangements of the adjacent juxtamembrane region supporting alternation between protein-protein and protein-lipid interactions of this region that can be triggered by ligand binding. Also, the importance of juxtamembrane SS bonding for signal persistency, and somewhat unusual aspects of transmembrane region interaction with water molecules were demonstrated. CONCLUSIONS: Two alternative dimeric structures of GHR TMD attributed to dormant and active receptor states interchange via allosteric rearrangements of transmembrane helices and extracellular juxtamembrane regions that support coordination between protein-protein and protein-lipid interactions. GENERAL SIGNIFICANCE: This study provides a holistic vision of GHR signal transduction across the membrane emphasizing the role of protein-lipid interactions. PMID- 29571749 TI - Detecting agitation and aggression in people with dementia using sensors-A systematic review. AB - Agitation and aggression are among the most challenging symptoms of dementia. Agitated persons with dementia can harm themselves, their caregivers, or other patients in a care facility. Automatic detection of agitation would be useful to alert caregivers so that appropriate interventions can be performed. The building blocks in the automatic detection of agitation and aggression are appropriate sensing platforms and generalized predictive models. In this article, we perform a systematic review of studies that use different types of sensors to detect agitation and aggression in persons with dementia. We conclude that actigraphy shows some evidence of correlation with incidences of agitation and aggression; however, multimodal sensing has not been fully evaluated for this purpose. Based on this systematic review, we provide guidelines and recommendations for future research directions in this field. PMID- 29571747 TI - Cdk5 suppression blocks SIRT1 degradation via the ubiquitin-proteasome pathway in Parkinson's disease models. AB - The NAD+-dependent protein deacetylase sirtuin 1 (SIRT1), a member of the sirtuin family, may have a neuroprotective effect in multiple neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD) and Amyotrophic lateral sclerosis (ALS). Many studies have suggested that overexpression-induced or resveratrol-treated activation of SIRT1 could significantly ameliorate several neurodegenerative diseases in mouse models. However, the type of SIRT1, protein expression levels and underlying mechanisms remain unclear, especially in PD. In this study, the results demonstrated that SIRT1 knockout markedly worsened the movement function in MPTP-lesioned animal model of PD. SIRT1 expression was found to be markedly decreased not only in environmental factor PD models, neurotoxin MPP+-treated primary culture neurons and MPTP-induced mice but also in genetic factor PD models, overexpressed alpha-synuclein-A30PA53T SH-SY5Y stable cell line and hm2alpha-SYN-39 transgenic mouse strain. Importantly, the degradation of SIRT1 during MPP+ treatment was mediated by the ubiquitin-proteasome pathway. Furthermore, the results indicated that cyclin-dependent kinase 5 (Cdk5) was also involved in the decrease of SIRT1 expression, which could be efficiently blocked by the inhibition of Cdk5. In conclusion, our findings revealed that the Cdk5 dependent ubiquitin-proteasome pathway mediated degradation of SIRT1 plays a vital role in the progression of PD. PMID- 29571750 TI - [Presence of relatives during cardiopulmonary resuscitation: Perspectives of health professionals, patients and family in the Basque Country]. AB - OBJECTIVE: To determine the perception of nurses, doctors, patients and family or relatives being present during cardiopulmonary resuscitation (CPR) in adult patients. DESIGN: A qualitative exploratory study and thematic analysis were developed. SITE: Primary Care, Hospital Care and Emergency Service of the Basque Health Service. PARTICIPANTS: The selection of the participants was made through intentional sampling. Four focus groups were developed: one of patients and family, 2 of nurses, and one of physicians. METHOD: Thematic analysis was performed. Triangulation techniques were used between investigators and investigator-participant member. The Open code 4.1 statistics software was used. RESULTS: Three significant categories were identified: the impact on the family; the weight of ethical and legal responsibility; power, place of death, and cultural assumptions. CONCLUSIONS: CPR is a social construct influenced by values which are situated in specific socio-cultural contexts. In this study, patients and family members describe the fear and resistance to being present during CPR. Health professionals consider that their decision is complex, and each case must be assessed independently, and patients and relatives must be integrated into decision-making. Future research should explore in greater depth the subjective experience of relatives who have witnessed CPR and the impact of contextual and sociocultural elements from the perspectives of relatives. PMID- 29571751 TI - Early sustained recovery following first episode psychosis: Evidence from the AESOP10 follow-up study. AB - OBJECTIVE: To describe the characteristics of individuals with early sustained recovery following first episode psychosis. METHODS: Individuals with a first episode psychosis were followed-up for ten years. Comparisons were made between those with Early Sustained Recovery and those with Other Course types. RESULTS: Of 345 individuals, n=43 (12.5%) had Early Sustained Recovery. They were more likely than those with Other Course types to be female (OR=2.45; 95% CI: 1.25 4.81); employed (OR=2.39; 95% CI: 1.22-4.69); in a relationship (OR=2.68; 95% CI: 1.35-5.32); have a short DUP (OR=2.86; 95% CI: 1.37-5.88); and have a diagnosis other than schizophrenia, particularly mania (OR=6.39; 95% CI: 2.52-16.18) or brief psychosis (OR=3.64; 95% CI: 1.10-12.10). CONCLUSIONS: Sustained recovery from first episode psychosis occurs in a minority. PMID- 29571752 TI - The Italian version of the 16-item prodromal questionnaire (iPQ-16): Field-test and psychometric features. AB - OBJECTIVE: Among current early screeners for psychosis-risk states, the Prodromal Questionnaire-16 items (PQ-16) is often used. We aimed to assess validity and reliability of the Italian version of the PQ-16 in a young adult help-seeking population. METHODS: We included 154 individuals aged 18-35years seeking help at the Reggio Emilia outpatient mental health services in a large semirural catchment area (550.000 inhabitants). Participants completed the Italian version of the PQ-16 (iPQ-16) and were subsequently evaluated with the Comprehensive Assessment of At-Risk Mental States (CAARMS). We examined diagnostic accuracy (i.e. specificity, sensitivity, negative and positive likelihood ratios, and negative and positive predictive values) and content, convergent, and concurrent validity between PQ-16 and CAARMS using Cronbach's alpha, Spearman's rho, and Cohen's kappa, respectively. We also tested the validity of the adopted PQ-16 cut offs through Receiver Operating Characteristic (ROC) curves plotted against CAARMS diagnoses and the 1-year predictive validity of the PQ-16. RESULTS: The iPQ-16 showed high internal consistency and acceptable diagnostic accuracy and concurrent validity. ROC analyses pointed to a cut-off score of >=5 as best cut off. After 12months of follow-up, 8.7% of participants with a PQ-16 symptom total score of >=5 who were below the CAARMS psychosis threshold at the baseline, developed a psychotic disorder. CONCLUSIONS: Psychometric properties of the iPQ 16 were satisfactory. PMID- 29571754 TI - Carotid Intraplaque Hemorrhage in Patients with Embolic Stroke of Undetermined Source. AB - BACKGROUND: Many embolic strokes are of undetermined source (ESUS). Carotid artery intraplaque hemorrhage (IPH), an unstable component of atherosclerosis, may be an under-recognized etiology in patients with ESUS. We investigated the prevalence of carotid IPH detected noninvasively by magnetic resonance imaging (MRI). METHODS: This pilot study analyzed data from a prospective cohort of patients with a recent ESUS who underwent MRI for carotid IPH assessment. All patients had carotid artery stenosis of less than 50%. The primary outcome was the presence of carotid IPH ipsilateral to the cerebral ischemic event. RESULTS: The cohort comprised 35 consecutive patients with a recent carotid-territory ESUS who underwent carotid MRI (mean age 74.3 +/- 9.6 years). We found ipsilateral and contralateral IPH in 7 of 35 patients (20.0%) and in 3 of 35 patients (8.6%), respectively (P = .005). CONCLUSIONS: In this sample of patients with ESUS, 1 in 5 had carotid IPH ipsilateral to their acute infarct, as detected by MRI of the vessel wall. Further studies are warranted to investigate carotid IPH as an etiology of ESUS. PMID- 29571755 TI - Letter to the Editor Regarding "Yield of Computed Tomography (CT) Angiography in Patients with Acute Headache, Normal Neurological Examination, and Normal Non Contrast CT: A Meta-Analysis". PMID- 29571753 TI - Disrupted network cross talk, hippocampal dysfunction and hallucinations in schizophrenia. AB - Hallucinations characterize schizophrenia, with approximately 59% of patients reporting auditory hallucinations and 27% reporting visual hallucinations. Prior neuroimaging studies suggest that hallucinations are linked to disrupted communication across distributed (sensory, salience-monitoring and subcortical) networks. Yet, our understanding of the neurophysiological mechanisms that underlie auditory and visual hallucinations in schizophrenia remains limited. This study integrates two resting-state functional magnetic resonance imaging (fMRI) analysis methods - amplitudes of low-frequency fluctuations (ALFF) and functional network connectivity (FNC) - to explore the hypotheses that (1) abnormal FNC between salience and sensory (visual/auditory) networks underlies hallucinations in schizophrenia, and (2) disrupted hippocampal oscillations (as measured by hippocampal ALFF) beget changes in FNC linked to hallucinations. Our first hypothesis was supported by the finding that schizophrenia patients reporting hallucinations have higher FNC between the salience network and an associative auditory network relative to healthy controls. Hippocampal ALFF was negatively associated with FNC between primary auditory cortex and the salience network in healthy subjects, but was positively associated with FNC between these networks in patients reporting hallucinations. These findings provide indirect support favoring our second hypothesis. We suggest future studies integrate fMRI with electroencephalogram (EEG) and/or magnetoencephalogram (MEG) methods to directly probe the temporal relation between altered hippocampal oscillations and changes in cross-network functional communication. PMID- 29571756 TI - A Validated Swallow Screener for Dysphagia and Aspiration in Patients with Stroke. AB - BACKGROUND: Early detection of dysphagia is critical to reducing hospital complications and length of stay in patients with various types of strokes. The aim of this study was to develop and evaluate the DePaul Hospital Swallow Screener (DHSS) tool to assess for dysphagia in patients with stroke. METHODS: This prospective observational study investigated patients admitted to a comprehensive stroke center. The DHSS is composed of a questionnaire containing 8 nonswallow items and a water swallow test. All patients admitted under a standard stroke protocol are screened by the nursing staff using the DHSS and then objectively evaluated by a speech-language pathologist using the Mann Assessment of Swallowing Ability (MASA). Validity measures and reliability through Cohen's kappa-coefficient with associated 95% confidence intervals were calculated. RESULTS: A total of 224 patients completed the DHSS and had at least 1 MASA score. The overall Content Validity Index score for the DHSS was .92. Compared with the MASA dysphagia cutoff value, the DHSS had a specificity of 93% and a sensitivity of 69%, and compared with the MASA aspiration risk cutoff value, the DHSS had a specificity of 90% and a sensitivity of 70%. Stratified analysis for those with any documented stroke (ischemic or hemorrhagic) compared with those admitted with transient ischemic attack or no stroke yielded similar sensitivity and specificity in both dysphagia and aspiration risk. CONCLUSION: The DHSS is a valid and reliable swallow screening tool with moderate agreement, high specificity, and reliable predictive values when compared with the MASA. PMID- 29571757 TI - Memory Impairment Due to a Small Acute Infarction of the Columns of the Fornix. AB - BACKGROUND: Clinically infarction of the columns of the fornix is very rare. It is also easy to be overlooked during imaging examination due to the special anatomical localization and features of columns of the fornix. In the meantime, with memory disorder to be its most prominent manifestation, it is very easily false diagnosed as other diseases when the lesion focus is overlooked, causing unnecessary invasive examinations like cerebrospinal fluid tests. METHODS: Case report and Literature review. RESULTS: We presented a 66-year-old woman with memory impairment due to a small acute infarction of the columns of the fornix. Through her diagnosis and treatment, we believed that early diagnosis and treatment were important to these patients who were enduring the disease. In addition, literature review informed us that for those unwilling to undergo cerebral angiography or for small cerebrovascular lesions that cannot be detected by angiography, 7T magnetic resonance imaging (MRI) might be an ideal diagnostic method. CONCLUSION: This case illustrated the significance of MRI in diagnosis for patients with acute memory impairment. When reading MRI results, one needs to pay attention to identify small lesions at special locations. In addition, cerebral apoplexy is still the first consideration of diagnosis when acute memory impairment occurs in patients with cerebrovascular disease risk factors. PMID- 29571758 TI - S100beta Protein as a Predictor of Poststroke Functional Outcome: A Prospective Study. AB - BACKGROUND: Stroke is one of the leading causes of disability worldwide. Early prediction of poststroke disability using clinical models is of great interest, especially in the rehabilitation field. Although some biomarkers and neuroimaging techniques have shown potential predictive value, there are still insufficient data to support their clinical utility in predicting poststroke functional recovery. We aimed to assess the value of serum biomarkers (C-reactive protein [CRP], D-dimer, fibrinogen, and S100beta protein) in predicting medium-term (12 weeks) functional outcome in patients with acute ischemic stroke. METHODS: This is an observational, prospective study in a sample of patients hospitalized for ischemic stroke (N = 131). Peripheral blood levels of biomarkers of interest were determined at admission (CRP, D-dimer, and fibrinogen) or at 48 hours poststroke (S100beta protein). Functional status was accessed at 48 hours and 12 weeks poststroke using the modified Rankin Scale (mRS). RESULTS: S100beta protein levels measured at 48 hours were significantly associated with mRS scores at 12 weeks (odds ratio = 1.005, 95% confidence interval [CI] [1.005-1.007]; P <.001). This association was not seen for the remaining biomarkers of interest. The S100beta cutoff for poor functionality at 12 weeks was 140.5 ng/L or more (sensibility 83.8%; specificity 71.4%; area under the curve = .80, 95% CI [.722, .879]). CONCLUSIONS: S100beta levels in peripheral blood at 48 hours poststroke reflect acute stroke severity and predict functional outcome at 12 weeks with a cutoff value of 140.5 ng/dL. The value of S100beta as predictor of functional recovery after stroke should be emphasized in further clinical research and clinical practice. PMID- 29571759 TI - A Rare Case of Posterior Circulation Stroke Caused by Bronchial Artery Embolization. AB - Bronchial artery embolization (BAE) is an effective treatment for massive hemoptysis. Stroke is a rare complication of BAE, with only a few cases reported in the literature. We report one such case. Posterior circulation strokes after BAE can be caused by connections between the vertebral arteries and the bronchial arteries (shunting between pulmonary and systemic circulations), backflow of embolization material from the bronchial or intercostal arteries to the subclavian artery or through backflow of emblospheres into the aortic lumen leading to subsequent embolization of the cerebral circulation. New-onset focal neurologic signs, change in mental status, or delay in recovery from anesthesia after BAE warrants brain imaging to rule out a stroke. Our case had a poor outcome, unlike the majority of previously reported cases. PMID- 29571760 TI - The "Blush" Sign on Computed Tomography Angiography is an Independent Predictor of Hematoma Progression in Primary Hypertensive Hemorrhage. AB - BACKGROUND AND PURPOSE: Hypertension is an important etiology of intracerebral hemorrhage (ICH) in neurosurgical practice. Contrast extravasation on computed tomography angiography, known as the "spot sign", has been described as an independent predictor of hematoma progression and clinical deterioration. However, its role in hypertensive ICH alone has not been determined and is the primary aim of this study. MATERIALS AND METHODS: A retrospective review was carried out of patients with hypertensive ICH admitted to our institution between May 2014 and December 2016. Evaluation of the neuroimaging studies of these patients revealed two distinct morphologies, "spot" and "blush" sign. These distinct signs and covariates were tested for association with hematoma expansion and mortality using multivariate logistic regression. The accuracy of the "spot" and "blush" signs as predictors of hematoma expansion and mortality was determined using receiver-operator characteristic (ROC) analysis. RESULTS: A total of 54 patients were identified as hypertensive ICH during the study period. "spot" sign was observed in 11 (20.4%) of the study population. Contrast extravasation (blush-sign) was seen in 7 (14.8%) patients. The "blush" was an independent predictor of hematoma expansion (odds ratio [OR] 6.052; confidence interval [CI] 1.036-15.945 [P = .012]) and mortality (OR 3.305; CI 1.240-25.414 [P = .032]). With ROC analysis, the "blush" sign was found to have a better predictive value for significant hematoma expansion (area under the curve [AUC]: .795) than the spot sign (AUC: .432). CONCLUSION: The "blush" sign has better accuracy for predicting hematoma expansion in hypertensive ICH and could be used to risk stratify these patients for early therapeutic interventions. PMID- 29571761 TI - A New Technique for the Assessment of Cerebral Vasodilatory Capacity as Part of Catheter-Based Cerebral Angiography. AB - BACKGROUND: Previous studies have demonstrated the value of cerebral vasodilatory capacity assessment for risk stratification in patients with extracranial arterial stenosis or occlusion. We describe a new method that assesses cerebral vasodilatory capacity as part of catheter-based cerebral angiography. METHODS: We assessed regional cerebral blood volume (rCBV) in the arterial distribution of interest using a controlled contrast injection through a diagnostic catheter placed in the common carotid or the subclavian artery. rCBV maps were created using predefined algorithm based on contrast distribution in the venous phase (voxel size 0.466 mm3) into high, intermediate, low, and no detectable rCBV regions. rCBV maps were acquired again after the administration of intra-arterial nicardipine (1.5-2.5 mg), and percentage increases of the area of various grades of rCBV were calculated. RESULTS: Three patients with internal carotid artery stenosis (32% - 64% in severity) and 1 patient with extracranial vertebral artery stenosis (46% in severity) were assessed. There was a variable but consistent increase in the area of high rCBV in the ipsilateral hemisphere in 3 patients with internal carotid artery flow (5.5%-24.5%) and the cerebellum (9.6%) in 1 patient with vertebral artery flow assessments. The increase in high rCBV was most prominent in the patient who received 2.5 mg (24.5%) and least prominent in a patient who received 1.5 mg (5.5%) of intra-arterial nicardipine. There was a concurrent reduction in areas of intermediate and low rCBV (shift) in 3 patients, and there was an increase in all areas of rCBV grades (addition) in 1 patient. CONCLUSIONS: Selective assessment of cerebral vasodilatory response in the affected arterial distribution is feasible during catheter-based cerebral angiography. PMID- 29571762 TI - Bilateral Cerebral Infarctions and Intracardiac Thrombus in a Young Duchenne Muscular Dystrophy Patient. AB - A 31-year-old man with Duchenne muscular dystrophy was admitted to our center, having infarctions in bilateral cerebral hemispheres and an occluded right middle cerebral artery. His right middle cerebral artery was spontaneous recanalization on the next day, and thrombus in the left ventricle vanished on the eighth day after giving warfarin. PMID- 29571763 TI - Plaque Characteristics of Patients with Symptomatic Mild Carotid Artery Stenosis. AB - BACKGROUND: Carotid revascularization may be considered for severe stenosis, but its use for symptomatic mild stenosis (<50%) with vulnerable plaque or ulcer remains uncertain. The characteristics of patients with symptomatic mild stenosis who underwent revascularization are reviewed. METHODS: The subjects of this study were 18 patients with symptomatic mild stenosis (<50%) on angiography from among 175 patients who underwent revascularization in our department. The plaques were evaluated by black-blood magnetic resonance imaging (BB-MRI) and ultrasonography (US) and classified into 2 types: type 1 (n = 15), a lesion with an ulcer or mobile plaque or thrombosis on angiography or US; and type 2 (n = 3), a lesion without any of the above. Fourteen patients underwent carotid endarterectomy (CEA), and 4 patients underwent carotid artery stenting. RESULTS: The stenosis on angiography was 27.2% +/- 10.7 (5%-41%), and the area carotid artery stenosis rate on US was 69.8 +/- 14.5% (44.5%-97%). The stenosis rate of these 2 methods was not at all correlated. In type 1 plaque that underwent CEA, 10 of 11 patients had vulnerable plaque by histopathology, and 1 patient had thrombus on the plaque by operative findings. In type 2 plaque that underwent CEA, all patients had vulnerable plaque by histopathology. During the follow-up period, none of the patients had restenosis or stroke. CONCLUSIONS: The findings of US and BB-MRI in patients with symptomatic mild stenosis (<50%) on angiography are important for determining treatment. If BB-MRI or US shows the findings of vulnerable plaque in mild stenosis, surgical treatment may be considered for these patients. PMID- 29571764 TI - Retinal Microvascular Abnormalities as Surrogate Markers of Cerebrovascular Ischemic Disease: A Meta-Analysis. AB - BACKGROUND: To determine the predictive value of retinal microvascular abnormalities for cerebrovascular ischemic diseases (CVDs), we aimed to investigate the quantitative association between retinal microvascular changes and CVD subcategories: white matter hyperintensities (WMHIs), lacunar infarcts (LIs), and cerebral infarctions (CIs). METHODS: Using Meta-analyses Of Observational Studies in Epidemiology guidelines, we searched 6 databases through September 2016 for studies evaluating the linkage between retinal microvascular abnormalities and WMHI, and LI and CI. Studies were included if they reported odds ratios (ORs) and 95% confidence intervals or raw patient level data (that were computed into ORs). Unadjusted and vascular risk-factor adjusted ORs were pooled into meta-analysis using DerSimonian Laird random effects model. Study quality and dissemination biases were assessed and integrated. RESULTS: From 24,444 search-identified records, 28 prospective studies encompassing 56,379 patients were eligible for the meta-analysis. After vascular risk-factor adjustment, focal arteriolar narrowing was associated with WMHI (OR, 1.24 [1.01 1.79]), LI (OR, 1.77 [1.14-2.74]), and CI (OR, 1.75 [1.14-2.69]). Venular dilation was associated with LI (OR, 1.46 [1.10-1.93]), and retinal hemorrhages with WMHI (OR, 2.23 [1.34-3.70]). Any retinopathy exhibited significant association with CI (OR, 1.96 [1.65-2.50]). Heterogeneity was significant (I2>50%) for all syntheses except retinal hemorrhages and WMHI, and retinopathy and CI (I2=0 ? 0%). Associations remained significant after adjustments for quality and publication bias. CONCLUSIONS: We found the most significant association between retinal hemorrhages and WMHI. Focal arteriolar narrowing and retinopathy predicted CVD subtypes after risk-factor adjustment, suggesting that features different than traditional vascular risk factors, are involved in CVD pathophysiology. PMID- 29571765 TI - Paradoxical Brain Embolism in Elderly Subjects with Small Atrial Septal Defects. AB - BACKGROUND: Atrial septal defects have a low prevalence in the general population, and are recognized as a rare cause of paradoxical brain embolism. METHODS: We extensively examined stroke causes in patients with acute stroke admitted to a single stroke center within 1 year. RESULTS: Among 186 consecutive patients, transesophageal or transthoracic echocardiography revealed 5 cases of paradoxical brain embolism: 3 (1.6%) were related to atrial septal defects, whereas 2 were patent foramen ovale patients. Although right-to-left shunt may have occurred after the development of acute pulmonary embolism in atrial septal defects case #1, the Valsalva maneuver elicited right-to-left shunt in atrial septal defects cases #2 and #3. The 3 cases were elderly (>60 years old), harbored small defects with normal systemic hemodynamics, and had not experienced any clinical symptoms related to atrial septal defects. CONCLUSIONS: Small atrial septal defect may cause paradoxical embolism as its initial related event, particularly in elderly subjects. PMID- 29571766 TI - Dehydroepiandrosterone reduces accumulation of lipid droplets in primary chicken hepatocytes by biotransformation mediated via the cAMP/PKA-ERK1/2 signaling pathway. AB - Dehydroepiandrosterone (DHEA) is commonly used as a nutritional supplement to control fat deposition, but the mechanism of this action is poorly understood. In this study, we demonstrated that DHEA increased phosphorylation of AMP-activated protein kinase (p-AMPK). Elevated p-AMPK levels resulted in reduced expression of sterol regulatory element binding protein-1c, acetyl CoA carboxylase, fatty acid synthase and enhanced expression of peroxisome proliferators-activated receptor alpha and carnitine palmitoyl transferase-I, ultimately leading to the reduction of lipid droplet accumulation in primary chicken hepatocytes. We found that DHEA activates the cyclic adenosine 3', 5'-monophosphate/protein kinase A - extracellular signal-regulated kinase 1/2 (cAMP/PKA-ERK1/2) signaling pathway, which regulates the conversion of DHEA into testosterone and estradiol by increasing the 17beta-hydroxysteroid dehydrogenase and aromatase protein expression. Importantly, the fat-reducing effects of DHEA are more closely associated with the conversion of DHEA into estradiol than with the action of DHEA itself as an active biomolecule, or to its alternative metabolite, testosterone. Taken together, our results indicate that DHEA is converted into active hormones through activation of the cAMP/PKA-ERK1/2 signaling pathway; the fat-reducing effects of DHEA are achieved through its conversion into estradiol, not testosterone, and not through direct action of DHEA itself, which led to the activation of the p-AMPK in primary chicken hepatocytes. These data provide novel insight into the mechanisms underlying the action of DHEA in preventing fat deposition, and suggest potential applications for DHEA treatment to control fat deposition or as an agent to treat disorders related to lipid metabolism in animals and humans. PMID- 29571767 TI - Phospholipase D1 downregulation by alpha-synuclein: Implications for neurodegeneration in Parkinson's disease. AB - We have previously shown that phospholipase D (PLD) pathways have a role in neuronal degeneration; in particular, we found that PLD activation is associated with synaptic injury induced by oxidative stress. In the present study, we investigated the effect of alpha-synuclein (alpha-syn) overexpression on PLD signaling. Wild Type (WT) alpha-syn was found to trigger the inhibition of PLD1 expression as well as a decrease in ERK1/2 phosphorylation and expression levels. Moreover, ERK1/2 subcellular localization was shown to be modulated by WT alpha syn in a PLD1-dependent manner. Indeed, PLD1 inhibition was found to alter the neurofilament network and F-actin distribution regardless of the presence of WT alpha-syn. In line with this, neuroblastoma cells expressing WT alpha-syn exhibited a degenerative-like phenotype characterized by a marked reduction in neurofilament light subunit (NFL) expression and the rearrangement of the F-actin organization, compared with either the untransfected or the empty vector transfected cells. The gain of function of PLD1 through the overexpression of its active form had the effect of restoring NFL expression in WT alpha-syn neurons. Taken together, our findings reveal an unforeseen role for alpha-syn in PLD regulation: PLD1 downregulation may constitute an early mechanism in the initial stages of WT alpha-syn-triggered neurodegeneration.

AB - The immunostimulatory effects of Rhodomyrtus tomentosa leaf extract were evaluated in rainbow trout through changes in expression profile of genes involved in innate immune and antioxidant response, hematology and stress indicators. The concentrations of R. tomentosa at 10 and 100 MUg per fish were administrated by intraperitoneal injection, alone or in combination with LPS. After 6 h of administration, the gene expression was measured in head kidney, spleen, and intestine. Results indicated that R. tomentosa exerted immunostimulatory effects by inducing the expression of il10, saa, hepcidin, and sod in head kidney and the expression of il10, tgfbeta, and inos in intestine. In combination with LPS, the plant suppressed the expression of pro-inflammtory cytokine il1beta, il8 and other consisting of saa and gpx1 in head kidney and il1beta in spleen, pointing out its anti-inflammatory activities. Furthermore, the plant did not exert any impact on hematological parameters, but it was able to reduce cortisol levels when co-administered with LPS, indicating that R. tomentosa could attenuate stress response in rainbow trout. Our observations suggest that R. tomentosa induced the expression of genes involved in cytokine and innate immune response and modulated the physiological stress response as indicated by the suppressed cortisol in rainbow trout. PMID- 29571769 TI - Serum biochemistry, histology and transcriptomic profile analysis reflect liver inflammation and damage following dietary histamine supplementation in yellow catfish (Pelteobagrus fulvidraco). AB - Previous studies suggested that diets containing high levels of histamine influenced digestive system of aquatic animals. In addition, the exogenous histamine was first detoxified by diamine oxidase in the intestine, while the rest of histamine was further detoxified in the liver. Thus, based on the evidence from the previous studies, we hypothesized that high levels of histamine may lead to damage on liver of the aquatic animals. Here, in current attempt, we sought to investigate the toxic effect of histamine on yellow catfish (Pelteobagrus fulvidraco) liver physiology and pathogenesis. In the present study, yellow catfish were fed for 56 days on diets supplemented with 1000 mg kg 1 histamine (His) or a basal diet as the control group (Con). A significant change on the morphology of the intestine and liver was observed, followed with an induction of serum activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Furthermore, the transcriptomic analysis was performed to gain an overview of the gene expression profile in liver between control and histamine supplemented groups. Through the bioinformatics analysis, 431 differentially expressed genes were identified. Among these genes, Gene Ontology enrichment analysis (GO) suggests that immune-related genes are significantly dysregulated. In addition, TNF signaling pathway is enriched in Kyoto Encyclopedia of Genes and Genomes analysis (KEGG), and is also the dominant pathway in immune system, suggesting that the inflammatory response and apoptosis of hepatocytes are induced by exogenous histamine.

AB - OBJECTIVE: To investigate the influence of different CT reconstruction parameters on coronary artery calcium scoring (CACS) values and reclassification of predicted cardiovascular (CV) risk. METHODS: CACS was evaluated in 113 patients undergoing ECG-gated 64-slice CT. Reference CACS protocol included standard kernel filter (B35f) with slice thickness/increment of 3/1.5 mm, and field-of view (FOV) of 150-180 mm. Influence of different image reconstruction algorithms (reconstructed slice thickness/increment 2.0/1.0-1.5/0.8-3.0/2.0-3.0/3.0 mm; slice kernel B30f-B45f; FOV 200-250 mm) on Agatston score was assessed by Bland Altman plots and concordance correlation coefficient (CCC) analysis. Classification of CV risk was based on the Mayo Clinic classification. RESULTS: Different CACS reconstruction parameters showed overall good accuracy and precision when compared with reference protocol. Protocols with larger FOV, thinner slices and sharper kernels were associated with significant CV risk reclassification. Use of kernel B45f showed a moderate positive correlation with reference CACS protocol (Agatston CCC = 0.67), and yielded significantly higher CACS values (p < .05). Reconstruction parameters using B30f or B45f kernels, 250 mm FOV, or slice thickness/increment of 2.0/1.0 mm or 1.5/0.8 mm, were associated with significant reclassification of CV risk (p < .05). CONCLUSIONS: Kernel, FOV, slice thickness and increment are major determinants of accuracy and precision of CACS measurement. Despite high agreement and overall good correlation of different reconstruction protocols, thinner slices thickness and increment, and sharper kernels were associated with significant upward reclassification of CV risk. Larger FOV determined both upward and downward reclassification of CV risk. PMID- 29571782 TI - Attenuation values of renal parenchyma in virtual noncontrast images acquired from multiphase renal dual-energy CT: Comparison with standard noncontrast CT. AB - OBJECTIVES: To compare the renal parenchyma attenuation of virtual noncontrast (VNC) images derived from multiphase renal dual-energy computed tomography (DECT) with standard noncontrast (SNC) images, and to determine the optimum phase for VNC images. MATERIALS AND METHODS: Twenty-nine men and 16 women (mean age, 61 +/- 13 years; range, 37-89 years) underwent dynamic renal DECT (100/Sn140 kVp) were included in this institutional review board-approved retrospective study. There were four phases of the scan, which included noncontrast, corticomedullary (CMP), nephrographic (NP), and excretory phases (EP). The VNC images was generated from CMP, NP and EP. CT numbers of SNC images and VNC images of each phases were measured in the renal cortex and medulla. Mean standard deviation of subcutaneous fat was measured as image noise on SNC and VNC images. Radiation dose was recorded and potential radiation dose reduction was estimated. Results were tested for statistical significance using the unpaired t-test and agreement using Bland-Altman plot analysis. RESULTS: The difference in mean attenuation between SNC and each phase of VNC images were <=4 HU. The mean attenuation of renal cortex and medulla was 33.2 +/- 4.4 HU, and 34.2 +/- 4.8 HU in SNC, 33.6 +/- 7.6 HU and 31.1 +/- 8.3 HU in VNC of CMP, 34.8 +/- 8.6 HU and 35.6 +/- 8.5 HU in VNC of NP, 31.5 +/- 7.6 HU and 32.4 +/- 7.5 HU in VNC of EP. In VNC of CMP, the attenuation of the cortex was higher than the medulla (p < 0.05), and the attenuation of medulla was significant lower than that of SNC (p < 0.01). In VNC of NP, the attenuation of renal cortex was higher than SNC (p < 0.05). In VNC of EP, the attenuation of cortex and medulla were lower than SNC (p < 0.05), and inadequate iodine subtraction in collecting system was noted. Image noise was significantly greater in SNC (p < 0.001). Mean radiation dose reduction achievable by removing the SNC was 12.3% +/- 0.9%. CONCLUSIONS: VNC images from multiphase renal DECT were similar to SNC images. Using the nephrographic phase can gives more comparable VNC images to SNC images in renal parenchyma than other phases. PMID- 29571783 TI - Beam-hardening in 70-kV Coronary CT angiography: Artifact reduction using an advanced post-processing algorithm. AB - PURPOSE: To investigate the effect of an iterative beam-hardening correction algorithm (iBHC) on artifact reduction and image quality in coronary CT angiography (cCTA) with low tube voltage. MATERIAL AND METHODS: Thirty-six patients (17 male, mean age, 57.3 +/- 14.5 years) were prospectively enrolled in this IRB-approved study and underwent 70-kV cCTA using a third-generation dual source CT scanner. Images were reconstructed using a standard algorithm (Bv36) both with and without the iBHC technique. Several region-of-interest (ROI) measurements were performed in the inferior wall of the left ventricle (LV), an area prone to beam-hardening, as well as other myocardial regions. Coronary contrast-to-noise (CNR) and signal-to-noise ratios (SNR) were calculated. Two radiologists assessed subjective image quality. RESULTS: The iBHC algorithm generally increased myocardial attenuation in all ROIs (P < 0.566); however, the increase was significantly more distinct in beam-hardening prone areas such as the inferior LV (increase, +13.9 HU, +18.6%, P < 0.001), compared to the remaining myocardium (increase, +4.4 HU, +4.5%, P < 0.003). While no significant difference was found for image noise (P < 0.092), greater CNR and SNR values for the left main coronary artery (increase, +20.7% and +17.3%, respectively) were found using the iBHC algorithm (both with P < 0.001). Subjective image quality was comparable between both image series (P = 0.217). CONCLUSION: The iBHC post processing algorithm leads to significantly reduced beam-hardening while providing improved objective and equivalent subjective image quality in 70-kV cCTA. PMID- 29571784 TI - Predictive factors for treatment response using dual-energy computed tomography in patients with advanced lung adenocarcinoma. AB - PURPOSE: This study aimed to investigate whether the quantitative parameters of dual-energy computed tomography (DECT) can predict the effects of chemotherapy in advanced adenocarcinoma based on the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines. MATERIALS AND METHODS: A total of 90 patients (59 males, 31 females, age 61.4 +/- 12.3 (23-85)) with unresectable lung adenocarcinoma (TNM stage IIIB or IV) who underwent DECT before chemotherapy were prospectively included in this study. By comparing baseline studies with the best response achieved during 1 st line chemotherapy, patients were divided into two groups according to RECIST (version 1.1) guidelines as follows; responders (CR or PR) and non-responders (SD or PD). Quantitative measurements were performed on baseline DECT, and a logistic regression model was used to evaluate predictive factors for a response to chemotherapy. RESULTS: Among 90 patients, 38 were categorized as responders, while 52 patients were non-responders. The mean iodine concentration measurements were significantly higher in responders compared with non-responders (1.81 +/- 0.51 vs 1.33 +/- 0.76 mg/ml, p < 0.001). On multivariate analysis, EGFR mutation (odds ratio (OR): 3.116, 95% confidential interval (CI):1.182-8.213, p = .019) and iodine concentration (OR: 1.112, 95% CI:1.034 1.196, p = .006) were found to be significant for predicting a treatment response. CONCLUSIONS: Dual-energy CT using a quantitative analytic method based on iodine concentration measurements can be used to predict the effects of chemotherapy in patients with advanced adenocarcinoma. PMID- 29571785 TI - Low-dose chest computed tomography screening of subjects exposed to asbestos. AB - OBJECTIVES: The primary aim was to reveal the prevalence of lung cancer (LC) and malignant pleural mesothelioma (MPM) in subjects with past asbestos exposure (AE). We also examined pulmonary or pleural changes correlated with the development of LC. MATERIALS AND METHODS: This was a prospective, multicenter, cross-sectional study. There were 2132 subjects enrolled between 2010 and 2012. They included 96.2% men and 3.8% women, with a mean age of 76.1 years; 78.8% former or current smokers; and 21.2% never smokers. We screened subjects using low-dose computed tomography (CT). The CT images were taken with a CT dose Index of 2.7 mGy. The evaluated CT findings included subpleural curvilinear shadow/subpleural dots, ground glass opacity or interlobular reticular opacity, traction bronchiectasia, honeycombing change, parenchymal band, emphysema changes, pleural effusion, diffuse pleural thickening, rounded atelectasis, pleural plaques (PQs), and tumor formation. RESULTS: The PQs were detected in most of subjects (89.4%) and emphysema changes were seen in 46.0%. Fibrotic changes were detected in 565 cases (26.5%). A pathological diagnosis of LC was confirmed in 45 cases (2.1%) and MPM was confirmed in 7 cases (0.3%). The prevalence of LC was 2.5% in patients with a smoking history, which was significantly higher than that in never smokers (0.7%, p = 0.027). The prevalence of LC was 2.8% in subjects with emphysema changes, which was higher than that of subjects without those findings (1.6%); although, the difference was not statistically significant (p = 0.056). The prevalence of LC in subjects with both fibrotic plus emphysema changes was 4.0%, which was significantly higher than that of subjects with neither of those findings (1.8%, p = 0.011). Logistic regression analysis revealed smoking history, fibrotic plus emphysema changes, and pleural effusion as significant explanatory variables. CONCLUSIONS: Smoking history, fibrotic plus emphysema changes, and pleural effusion were correlated with the prevalence of LC. PMID- 29571786 TI - Dynamic contrast enhanced magnetic resonance lymphangiography: Categorization of imaging findings and correlation with patient management. AB - OBJECTIVE: To review the technical aspects and categorize the imaging findings of dynamic contrast enhanced magnetic resonance lymphangiography (DCMRL) and correlate the findings with patient management options. MATERIALS AND METHODS: A retrospective review of patients who underwent DCMRL between June 2012 and August 2017 at a tertiary care paediatric hospital was performed. Twenty-five DCMRL studies were performed in 23 patients (9 males, 13 females, 1 ambiguous gender) with a median age of 4 years (range: 1 month-29 years). DCMRL imaging findings were reviewed, categorized and the impact on patient management was studied. RESULTS: DCMRL was technically successful in 23/25 (92%) studies. DCMRL findings were categorized based on the status of central conducting lymphatics (CCL) and alternate lymphatic pathways as follows: Type 1 - normal CCL with no alternate lymphatic pathways, Type 2 - partial (2a) or complete (2b) non-visualization of CCL with reflux of contrast into alternate pathways and Type 3 - normal CCL with additional filling of alternate pathways. Type 1 DCMRL patients (n = 5) were reassured and conservative management was continued, Type 2 patients (n = 10) had evidence of CCL obstruction hence thoracic duct ligation or embolization was avoided and other options such as lymphatic fluid diversion using Denver(r) shunt or lympho-venous anastomosis were used, and Type 3 patients (n = 8) were evaluated for elevated central venous pressure as a cause of lymphatic backflow in addition to Denver(r) shunt, lympho-venous anastomosis, thoracic duct ligation or embolization. CONCLUSION: DCMRL is an evolving imaging technique for understanding abnormalities of the central conducting lymphatics. Categorization of imaging findings may be helpful in guiding selection of management options. PMID- 29571787 TI - Advantages of high b-value diffusion-weighted imaging for preoperative differential diagnosis between embryonal and ependymal tumors at 3 T MRI. AB - PURPOSE: It is often difficult to distinguish between embryonal and ependymal tumors using conventional MR imaging. The apparent diffusion coefficient (ADC) calculated from diffusion-weighted images (DWI) has been widely used for diagnosis, but its usefulness for differential diagnosis between embryonal and ependymal tumors has not been determined yet. Both DWI properties and ADC values of these two types of tumor at regular and high b-values on a 3 T MR scanner were retrospectively reviewed. MATERIALS AND METHODS: DWI at 3 T was acquired for 16 patients with embryonal tumors (including medulloblastoma, CNS embryonal tumors (NOS), and atypical teratoid/rhabdoid tumor), and 7 patients with ependymal tumors (including ependymoma and anaplastic ependymoma). ADC was measured by manually placing multiple regions of interest (ROIs) on ADC maps corresponding to enhancing lesions on contrast-enhanced T1-weighted images, both on standard (b 1000) and high (b-4000) b-value DWI. The minimum ADC (ADC-MIN) was calculated from several ROIs placed on each tumor. The relationship between tumor cell density and ADC-MIN was also investigated. RESULTS: Both at b-1000 and b-4000, ADC-MIN was significantly lower in embryonal tumors than in ependymal tumors. Embryonal tumors could be completely discriminated from ependymal tumors using both b-values, but ADC-MIN at b-4000 (t-value = -8.312, p < 0.001) was better than ADC-MIN at b-1000. There was a stronger negative correlation between cell density and ADC-MIN at b-4000 (r2 = 0.50, p < 0.001) than with ADC-MIN at b-1000 (r2 = 0.41, p < 0.001). CONCLUSION: Evaluating ADC-MIN at b-4000 would be a useful tool for distinguishing embryonal from ependymal tumors. PMID- 29571788 TI - Network-wise cerebral blood flow redistribution after 20 Hz rTMS on left dorso lateral prefrontal cortex. AB - The repetitive application of transcranial magnetic stimulation (rTMS) on left dorsolateral prefrontal cortex (DLPFC) has been consistently shown to be beneficial for treating various neuropsychiatric or neuropsychological disorders, but its neural mechanisms still remain unclear. The purpose of this study was to measure the effects of high-frequency left DLPFC rTMS using cerebral blood flow (CBF) collected from 40 young healthy subjects before and after applying 20 Hz left DLPFC rTMS or SHAM stimulations. Relative CBF (rCBF) changes before and after 20 Hz rTMS or SHAM were assessed with paired-t test. The results show that 20 Hz DLPFC rTMS induced CBF redistribution in the default mode network, including increased rCBF in left medial temporal cortex (MTC)/hippocampus, but reduced rCBF in precuneus and cerebellum. Meanwhile, SHAM stimulation didn't produce any rCBF changes. After controlling SHAM effects, only the rCBF increase in MTC/hippocampus remained. Those data suggest that the beneficial effects of high-frequency rTMS may be through a within-network rCBF redistribution. PMID- 29571789 TI - Virtual single source CT using dual source acquisition: Clinical applicability in run-off CT-angiography for intra-individual comparison of different scan protocols. AB - PURPOSE: Virtual single source computed tomography (VSS-CT) acquisition on a dual source CT (DSCT) has been demonstrated to allow for dose-neutral intra-individual comparison of three acquisition protocols at different radiation dose levels (RDL) within one acquisition in a phantom. The purpose of this study was twofold: first to evaluate the applicability of VSS-CT in patients and second to optimize the task-dependent trade-off between radiation dose and image quality of lower extremity CT angiography (run-off CTA). MATERIAL AND METHODS: In this IRB approved prospective study 52 patients underwent run-off CTA between 06/2012 and 06/2013. VSS-CT acquisition was conducted using a first generation DSCT applying equal X-ray tube settings (120 kVp), collimation (2 * 32 * 0.6 mm), and slice thickness (1.0 mm) but different effective tube current-time products (tube A: 80 mAs, tube B: 40 mAs). Three different image datasets representing three different radiation dose levels (RDL40, RDL80, RDL120) were reconstructed using a soft kernel from the raw data of tube B, tube A or both tubes combined. Dose length products (DLP) of each raw data set were documented. Quantitative image quality (IQ) was assessed for five anatomical levels using image noise and contrast-to noise ratio (CNR). To investigate dose efficiency of each acquisition, the dose weighted CNR (CNRD) was determined. Qualitative IQ was evaluated by two blinded readers in consensus using a 5-point Likert scale and compared with a Friedman- and posthoc Wilcoxon test. RESULTS: Mean DLP was 200 +/- 40, 400 +/- 90 and 600 +/- 130 mGy.cm for the RDL40, RDL80 and RDL120, respectively. Image noise and CNR were best for RDL120 and decreased significantly for RDL80 and RDL40, independent of the anatomic level (p < 0.001). CNRD showed no significant differences at the abdominal and pelvic level between the investigated radiation dose levels. However, for thigh to foot level a significant increase of CNRD was noted between RDL120, RDL80 and RDL40. Significant differences of qualitative IQ were observed between RDL120 and RDL40 from the abdominal to the foot level, whereas no difference was seen for the other dose levels. CONCLUSION: Radiation dose splitting with VSS-CT can be applied to run-off CTA facilitating intra-individual comparison of different acquisition protocols without additional radiation exposure. Furthermore, a radiation dose reduction potential for run-off CTA of approximately 1/3 as compared to the acquisition protocol recommended by the manufacturer could be identified in this study. PMID- 29571790 TI - Breast strain elastography: Observer variability in data acquisition and interpretation. AB - OBJECTIVE: To analyze the observer reproducibility of breast strain elastography in elasticity image acquisition and elasticity image interpretation. METHODS: This was an institutional ethics committee approved prospective study. One hundred twenty-four breast lesions in 118 women (mean age 45.39 +/- 12.97 years old, range 21-77 years old) were examined with strain elastography by two blinded radiologists in turn. Three blinded observers separately reviewed and recorded the elasticity score of each lesion obtained by the two performers. The interobserver reproducibility of elasticity image acquisition between the two performers, the interobserver and intraobserver reproducibility of elasticity image interpretation among observers were evaluated. The diagnostic performance of strain elastography was compared between the two performers. RESULTS: Fifty three lesions were malignant and 71 were benign. The interobserver kappa value was 0.438 for the elasticity score between the two performers. Between the three observers, the overall interobserver and intraobserver kappa value was 0.365 and 0.655, respectively. There was no significant difference of the area under the receiver operator characteristic curve (Az) value for the elasticity score between performer 1 and 2 (P = 0.143). CONCLUSIONS: Our results suggested moderate interobserver reproducibility in breast strain elasticity image acquisition, poor interobserver and good intraobserver agreement in image interpretation. PMID- 29571791 TI - Utility of MRI with morphologic and diffusion weighted imaging in the detection of post-treatment nodal disease in head and neck squamous cell carcinoma. AB - PURPOSE: To determine the diagnostic performance of morphologic MRI with diffusion weighted imaging (DWIMRI) for the detection of post-treatment lymph node (LN) recurrence of head and neck squamous cell carcinoma (HNSCC). METHODS: This retrospective study is based on 33 HNSCC patients who underwent DWIMRI with apparent diffusion coefficient (ADC) measurements for suspected post-treatment loco-regional failure. Two radiologists, blinded to clinical/histopathological data, analyzed MR images according to established morphologic criteria and measured ADC values by drawing regions of interest on each normal/abnormal looking lymph node (LN). Histopathological findings in 40 neck dissections, 133 LN-levels and 755 LNs served as gold standard. RESULTS: Malignant LNs had lower ADCmean values than benign LNs (1.15 +/- 0.35 * 10-3 mm2/s versus 1.28 +/- 0.28 * 10-3 mm2/s, p = .028). The optimal ADCmean threshold to differentiate malignant from benign LNs was 1.1695 * 10-3 mm2/s. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values (95%CI in parentheses) of DWIMRI with morphologic criteria and ADCmean <1.1695 * 10-3 mm2/s were: (a) 100%(86.2;100), 44.4%(15.3;77.3), 86.1%(69.7;94.7), and 100%(39.5;100) per neck dissection; (b) 83.6%(69.7;92.2), 91.6%(83.0;96.2), 85.4%(71.6;93.4), and 90.5%(81.7;95.5) per LN level; (c) 53.1%(43.5;62.4), 95.5%(93.5;96.9), 67.4%(56.6;76.7), and 92.0%(89.6;93.9) per LN, respectively. CONCLUSION: The high NPV of DWIMRI irrespective of analysis type (per neck dissection/per neck level/per lymph node) make it a useful follow-up tool after treatment. PMID- 29571792 TI - Diagnostic accuracy of biparametric vs multiparametric MRI in clinically significant prostate cancer: Comparison between readers with different experience. AB - BACKGROUND: MRI plays a crucial role to identify men with a high likelihood of clinically significant prostate cancer who require immediate biopsy. The added value of DCE MRI in combination with T2-weighted imaging and DWI is controversial (risks related to gadolinium administration, duration of MR exam, financial burden, effects on diagnostic performance). A comparison of a biparametric and a standard multiparametric MR imaging protocol, taking into account the different experience of the readers, may help to choose the best MR approach regarding diagnostic performance. PURPOSE: To determine the added value of dynamic contrasted-enhanced imaging (DCE) over T2-weighted imaging (T2-WI) and diffusion weighted imaging (DWI) for the detection of clinically significant prostate cancer, and to evaluate how it affects the diagnostic performance of three readers with different grade of experience in prostate imaging. MATERIALS AND METHODS: Eighty-five patients underwent prostate MR examination at 1.5 T MR scanner performed because of elevated prostate-specific antigen level and/or suspicion of prostate cancer at digital rectal examination. Two MR images sets (Set 1 = biparametric, Set 2 = multiparametric) were retrospectively and independently scored by three radiologists with 7, 3 and 1 years of experience in prostate MR imaging respectively, according to PI-RADS v2. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated by dichotomizing reader scores. Receiver operating characteristic (ROC) analysis was performed and areas under the curve (AUCs) were calculated for each reader and image set. A comparison of ROC curves was performed to test the difference between the areas under the ROC curves among the three readers. RESULTS: There was no significant difference regarding the detection of clinically significant tumor among the three readers between the two image sets. The AUC for the bi-parametric and multi-parametric MR imaging protocol was respectively 0.68-0.72 (Reader 1), 0.72-0.70 (Reader 2) and 0.60-0.54 (Reader 3). ROC curve comparison revealed no statistically significant differences for each protocol among the most experienced (Reader 1) and the other readers (Readers 2 3). CONCLUSION: The diagnostic accuracy of a bi-parametric MR imaging protocol consisting of T2-weighted imaging and DWI is comparable with that of a standard multi-parametric imaging protocol for the detection of clinically significant prostate cancer. The experience of the reader does not significantly modify the diagnostic performance of both MR protocols. PMID- 29571793 TI - Predictive quantitative sonographic features on classification of hot and cold thyroid nodules. AB - PURPOSE: This study investigated the potentiality of ultrasound imaging to classify hot and cold thyroid nodules on the basis of textural and morphological analysis. METHODS: In this research, 42 hypo (hot) and 42 hyper-function (cold) thyroid nodules were evaluated through the proposed method of computer aided diagnosis (CAD) system. To discover the difference between hot and cold nodules, 49 sonographic features (9 morphological, 40 textural) were extracted. A support vector machine classifier was utilized for the classification of LNs based on their extracted features. RESULTS: In the training set data, a combination of morphological and textural features represented the best performance with area under the receiver operating characteristic curve (AUC) of 0.992. Upon testing the data set, the proposed model could classify the hot and cold thyroid nodules with an AUC of 0.948. CONCLUSIONS: CAD method based on textural and morphological features is capable of distinguishing between hot from cold nodules via 2 Dimensional sonography. Therefore, it can be used as a supplementary technique in daily clinical practices to improve the radiologists' understanding of conventional ultrasound imaging for nodules characterization. PMID- 29571794 TI - Non-contrast enhanced magnetic resonance imaging detects mosaic signal intensity in early cystic fibrosis lung disease. AB - OBJECTIVES: To determine if morphological non-contrast enhanced magnetic resonance imaging (MRI) of the lung is sensitive to detect mosaic signal intensity in infants and preschool children with cystic fibrosis (CF). MATERIALS AND METHODS: 50 infant and preschool CF patients (mean age 3.5 +/- 1.4y, range 0 6y) routinely underwent morphological (T2-weighted turbo-spin echo sequence with half-Fourier acquisition, HASTE) and contrast-enhanced 4D perfusion MRI (gradient echo sequence with parallel imaging and echo sharing, TWIST). MRI studies were independently scored by two readers blinded for patient age and clinical data (experienced Reader 1 = R1, inexperienced Reader 2 = R2). The extent of lung parenchyma signal abnormalities on HASTE was rated for each lobe from 0 (normal), 1 (<50% of lobe affected) to 2 (>=50% of lobe affected). Perfusion MRI was rated according to the previously established MRI score, and served as the standard of reference. RESULTS: Inter-method agreement between MRI mosaic score and perfusion score was moderate with kappa = 0.58 (confidence interval 0.45-0.71) for R1, and with kappa = 0.59 (0.46-0.72) for R2. Bland-Altman analysis revealed a slight tendency of the mosaic score to underestimate perfusion abnormalities with a score bias of 0.48 for R1 and 0.46 for R2. Inter-reader agreement for mosaic score was substantial with kappa = 0.71 (0.62-0.79), and a low bias of 0.02. CONCLUSIONS: This study demonstrates that non-contrast enhanced MRI reliably detects mosaic signal intensity in infants and preschool children with CF, reflecting pulmonary blood volume distribution. It may thus be used as a surrogate for perfusion MRI if contrast material is contra-indicated or alternative techniques are not available. PMID- 29571795 TI - Texture analysis of apparent diffusion coefficient maps for treatment response assessment in prostate cancer bone metastases-A pilot study. AB - OBJECTIVE: To evaluate whole-lesion volumetric texture analysis of apparent diffusion coefficient (ADC) maps for assessing treatment response in prostate cancer bone metastases. MATERIALS AND METHODS: Texture analysis is performed in 12 treatment-naive patients with 34 metastases before treatment and at one, two, and three months after the initiation of androgen deprivation therapy. Four first order and 19 second-order statistical texture features are computed on the ADC maps in each lesion at every time point. Repeatability, inter-patient variability, and changes in the feature values under therapy are investigated. Spearman rank's correlation coefficients are calculated across time to demonstrate the relationship between the texture features and the serum prostate specific antigen (PSA) levels. RESULTS: With few exceptions, the texture features exhibited moderate to high precision. At the same time, Friedman's tests revealed that all first-order and second-order statistical texture features changed significantly in response to therapy. Thereby, the majority of texture features showed significant changes in their values at all post-treatment time points relative to baseline. Bivariate analysis detected significant correlations between the great majority of texture features and the serum PSA levels. Thereby, three first-order and six second-order statistical features showed strong correlations with the serum PSA levels across time. CONCLUSION: The findings in the present work indicate that whole-tumor volumetric texture analysis may be utilized for response assessment in prostate cancer bone metastases. The approach may be used as a complementary measure for treatment monitoring in conjunction with averaged ADC values.

PMID- 29571797 TI - Combined screening with mammography and ultrasound in a population-based screening program. AB - OBJECTIVES: To compare the performance of screening with mammography combined with ultrasound versus mammography alone in women at average risk for breast cancer. METHODS: 66,680 women underwent physician-performed ultrasound as an adjunct to screening mammography. Histological results and follow-up at one year were used as reference standard for sensitivity. Main outcome measures were cancer detection rate, sensitivity, recall rate, biopsy rate, and positive predictive value of biopsy for combined screening with mammography plus ultrasound versus mammography alone. RESULTS: The overall sensitivity of mammography only was 61.5% in women with dense breasts and 86.6% in women with non-dense breasts. The sensitivity of mammography plus ultrasound combined was 81.3% in women with dense breasts and 95.0% in women with non-dense breasts. Adjunctive ultrasound increased the recall rate from 10.5 to 16.5 per 1000 women screened, and increased the biopsy rate from 6.3 to 9.3 per 1000 women screened. The positive predictive value of biopsy was 55.5% (95% CI 50.6%-60.3%) for mammography alone and 43.3 (95% CI 39.4%-47.3%) for combined mammography plus ultrasound. CONCLUSIONS: Supplemental ultrasound improves cancer detection in screening of women at average risk for breast cancer. Recall rates and biopsy rates can be kept within acceptable limits. PMID- 29571798 TI - Diagnostic performance of coronary CT angiography with ultra-high-resolution CT: Comparison with invasive coronary angiography. AB - PURPOSE: Recently, ultra-high-resolution computed tomography (U-HRCT) with a 0.25 mm * 128-row detector was introduced. The purpose of this study was to evaluate the diagnostic performance of coronary CT angiography (CCTA) using U-HRCT. METHODS: This retrospective study included 38 consecutive patients with suspected coronary artery disease (CAD) who underwent CCTA with U-HRCT followed by invasive coronary angiography (ICA). Per-segment diameter stenosis was calculated. Diagnostic performance of CCTA relative to ICA as the reference standard was determined. For segments with >30% diameter stenosis, the correlation and agreement of percent diameter stenosis between CCTA and ICA were calculated. RESULTS: Obstructive CAD was observed in 65 segments (12%) of 51 vessels (45%) in 32 patients (84%) during ICA. The per-patient, vessel, and segment analyses showed a sensitivity of 100% (95% confidence interval [CI], 95%-100%), 96% (95% CI: 89%-99%) and 95% (95% CI: 89%-98%), respectively, and a specificity of 67% (95% CI: 38%-67%), 81% (95% CI: 75%-83%) and 96% (95% CI: 96%-97%), respectively. The percentage of diameter stenosis, as determined by CCTA, demonstrated an excellent correlation with ICA (R = 0.90; 95% CI: 0.83-0.95) and a slight significant overestimation (mean: 4% +/- 7%, p < .01), with the agreed range of limits being +/- 16%. The median effective radiation dose for CCTA was 5.4 mSv (range: 2.9-18.0 mSv). CONCLUSIONS: CCTA with U-HRCT demonstrated an excellent correlation and agreement with ICA in the quantification of coronary artery stenosis. PMID- 29571799 TI - Measurement of pediatric regional cerebral blood flow from 6 months to 15 years of age in a clinical population. AB - OBJECTIVES: To investigate changes in cerebral blood flow (CBF) in gray matter (GM) between 6 months and 15 years of age and to provide CBF values for the brain, GM, white matter (WM), hemispheres and lobes. METHODS: Between 2013 and 2016, we retrospectively included all clinical MRI examinations with arterial spin labeling (ASL). We excluded subjects with a condition potentially affecting brain perfusion. For each subject, mean values of CBF in the brain, GM, WM, hemispheres and lobes were calculated. GM CBF was fitted using linear, quadratic and cubic polynomial regression against age. Regression models were compared with Akaike's information criterion (AIC), and Likelihood Ratio tests. RESULTS: 84 children were included (44 females/40 males). Mean CBF values were 64.2 +/- 13.8 mL/100 g/min in GM, and 29.3 +/- 10.0 mL/100 g/min in WM. The best-fit model of brain perfusion was the cubic polynomial function (AIC = 672.7, versus respectively AIC = 673.9 and AIC = 674.1 with the linear negative function and the quadratic polynomial function). A statistically significant difference between the tested models demonstrating the superiority of the quadratic (p = 0.18) or cubic polynomial model (p = 0.06), over the negative linear regression model was not found. No effect of general anesthesia (p = 0.34) or of gender (p = 0.16) was found. CONCLUSION: we provided values for ASL CBF in the brain, GM, WM, hemispheres, and lobes over a wide pediatric age range, approximately showing inverted U-shaped changes in GM perfusion over the course of childhood. PMID- 29571800 TI - Central echogenic areas in thyroid nodules: Diagnostic performance in prediction of papillary cancer. AB - PURPOSE: To determine the diagnostic performance of the "central echogenic area" sonographic finding in differentiating papillary carcinomas from benign nodules and to how this finding may be used to improve fine needle aspiration(FNA) technique/utilization. MATERIALS AND METHODS: We retrospectively analyzed ultrasound guided FNAs of thyroid nodules between 1 and 3 cm for central echogenic areas. 92 patients (evenly distributed benign vs papillary carcinoma) were evaluated by a blinded reader for areas of non-shadowing homogenously echogenic centers within the nodules and correlated with FNA proven pathologic diagnosis. A selection of nodules with the central echogenic area finding were selected for further slide review to establish a pathologic basis for the finding. RESULTS: Diagnostic performance of the "central echogenic area" feature in papillary thyroid cancers was 52.2% sensitive and 91.3% specific for papillary thyroid carcinoma with a PPV of 85.7% and NPV of 65.6%. There was a significant correlation with a p < 0.01 between the central echogenic area finding and papillary carcinoma. On pathologic slide review, nodules with central echogenic areas consistently demonstrated a central scar with conglomerate fibrosis and very few viable cells. CONCLUSION: Despite its relatively low sensitivity, the central echogenic area finding is highly specific for papillary carcinoma of the thyroid and can be a useful sonographic finding in decisions regarding FNA. Additionally, due to the paucity of cells and high density of conglomerate fibrosis, central echogenic areas should be avoided during FNA to decrease the chance of an inadequate sample collection. PMID- 29571801 TI - Chest CT texture analysis for response assessment in systemic sclerosis. AB - PURPOSE: To evaluate the role of CT-textural features for monitoring lung involvement in subjects with systemic sclerosis(SSc) undergoing autologous stem cell transplantation(SCT) by comparison with semi-quantitative chest-CT, pulmonary function tests(PFT) and clinical parameters (modified Rodnan skin score[mRSS]). METHODS: In a retrospective single centre analysis, we identified 23 consecutive subjects(11male) with SSc between 07/2005 and 11/2016 that underwent chest CTs before, 6 and 12 months post-SCT. Response to therapy was defined at 6 months after transplantation as stabilisation or improvement in FVC > 10% and DLCOSB > 10%. CT-texture analysis(CTTA) including mean, entropy and uniformity were calculated. RESULTS: PFT classified the subjects into responders(18/23;78%) and non-responders(5/23;22%). mRSS improved in responders from 28.46 +/- 9.53 to 15.70 +/- 10.07 6 months after auto-SCT(p = .001) whereas in non-responders no significant improvement was registered. Fibrosis score increased significantly(mean2.33 +/- 1.23 vs.1.41 +/- 0.78; p = .005) in non responders after 6 and 12months. Significant lower mean intensity and entropy of skewness and higher uniformity of skewness was found in responders vs. non responders at baseline. Significant changes in CTTA-parameters were found in both responders and non-responders at 6months and only in responders also at 12months post-SCT. CONCLUSIONS: Changes in CT-textural features after SCT are associated with visual CT evaluation of SSc-related lung abnormalities, but complementary provide information about therapy-induced, structural pulmonary changes. PMID- 29571802 TI - Evaluation of median nerve by shear wave elastography and diffusion tensor imaging in carpal tunnel syndrome. AB - PURPOSE: The aim of the current study is to investigate the diagnostic role of shear-wave elastography and diffusion tensor imaging in patients with carpal tunnel syndrome. MATERIAL AND METHODS: The study included a total of 77 wrists; 18 normal, 35 wrists with mild, 9 wrists with moderate and 15 wrists with severe carpal tunnel syndrome. Elastography of the median nerve was performed by defining the boundaries of a segment of the nerve at sagittal plane at the level of proximal carpal row. Additionally, the cross-sectional area of the median nerve was evaluated. Fractional anisotropy and apparent diffusion coefficient measurements were carried out by placing region-of-interest at three levels: at pisiform bone (carpal tunnel inlet), mid carpal tunnel, and hook of hamate (carpal tunnel outlet). RESULTS: Patients with carpal tunnel syndrome had higher elasticity values of median nerve (53.0 kPa; IQR 40.8-77.0 kPa) compared to control subjects. (36.8 kPa; IQR 31.0-39.9 kPa) Patients with moderate-severe carpal tunnel syndrome had higher elasticity values (82 kPa; IQR 64.0-95.5 kPa) compared to patients with mild carpal tunnel syndrome. (44 kPa; IQR 32.5-59.5 kPa) Patients with carpal tunnel syndrome had lower fractional anisotropy at mid carpal level (0.382; IQR 0.330-0.495) compared to the control group. (0.494; IQR 0.434-0.537) Patients with moderate-severe carpal tunnel syndrome had lower fractional anisotropy values (0.366; IQR 0.331-0.407) and higher apparent diffusion coefficient values (1.509 mm2/s; IQR 1.374-1.733 mm2/s) compared to patients with mild carpal tunnel syndrome. (0,423; IQR 0.324-0.526 and 1.293 mm2/s; IQR 0.967-1.514 mm2/s) CONCLUSION: Shear-wave elastography and diffusion tensor imaging are helpful imaging modalities in diagnosing carpal tunnel syndrome and assessing its severity. PMID- 29571803 TI - Tumor response to neoadjuvant chemotherapy in patients with esophageal cancer assessed with CT and FDG-PET/CT - RECIST 1.1 vs. PERCIST 1.0. AB - PURPOSE: We compared the response classification systems Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) 1.0 for assessment of response to neoadjuvant chemotherapy in patients with esophageal cancer. MATERIALS AND METHODS: Prior to planned surgical resection, 62 patients with esophageal cancer underwent fluorodeoxyglucose (FDG)-PET/CT and contrast-enhanced CT examinations before and after receiving neoadjuvant chemotherapy. Primary tumor largest diameter, maximum standardized uptake value (SUVmax), peak lean body mass SUV (SULpeak), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were determined. Patients were divided into responders (grade 1b-3) and non-responders (grade 0-1a) according to pathological response. RESULTS: Concordance between RECIST 1.1 and PERCIST 1.0 for response classification was seen in 28 (45.2%) patients. For 18 defined as responders, the number of metabolic responders (partial metabolic response + complete metabolic response) shown by PERCIST 1.0 was 17 and the number of anatomic responders (partial response + complete response) shown by RECIST 1.1 was 13. To distinguish responders from non-responders, the area under the receiver operating characteristics curve values for reduced primary tumor largest diameter, SUVmax, SULpeak, MTV, and TLG were 0.724, 0.775, 0.781, 0.756, and 0.759, respectively. An optimal percent decrease in largest diameter cut-off value of 39.2% was found to have 66.7% sensitivity and 70.5% specificity, while that for SULpeak of 55.8% was 77.8% and 75.0%, respectively. CONCLUSIONS: As compared to RECIST 1.1, PERSIST 1.0 may be more suitable for evaluation of neoadjuvant therapeutic response to esophageal cancer. PMID- 29571804 TI - Diagnosis and staging of hepatocellular carcinoma (HCC): current guidelines. AB - One of the key strategies to improve the prognosis of HCC, beside prevention, is to diagnose the tumor in early stages, when the patient is asymptomatic and the liver function is preserved, because in this clinical situation effective therapies with survival benefit can be applied. Imaging techniques are a key tool in the surveillance and diagnosis of HCC. Screening should be based in US every 6 months and non-invasive diagnostic criteria of HCC based on imaging findings on dynamic-MR and/or dynamic-CT have been validated and thus, accepted in clinical guidelines. The typical vascular pattern depicted by HCC on CT and or MRI consists on arterial enhancement, stronger than the surrounding liver (wash-in), and hypodensity or hyposignal intensity compared to the surrounding liver (wash out) in the venous phase. This has a sensitivity of around 60% with a 96-100% specificity. Major improvements on liver imaging have been introduced in the latest years, adding functional information that can be quantified: the use of hepatobiliary contrast media for liver MRI, the inclusion of diffusion-weighted sequences in the standard protocols for liver MRI studies and new radiotracers for positron-emission tomography (PET). However, all them are still a matter of research prior to be incorporated in evidence based clinical decision making. This review summarizes the current knowledge about imaging techniques for the early diagnosis and staging of HCC, and it discusses the most relevant open questions. PMID- 29571805 TI - Imaging findings of hereditary renal tumors, a review of what the radiologist should know. AB - It is estimated that up to 8% of currently diagnosed renal cancers are part of a hereditary syndrome. The radiologist may be the first person to associate a renal tumor presenting during an imaging study to other manifestations of a hereditary syndrome. This diagnosis can have broad implications for the patient but also for other family members. This update reviews the current known associations and emerging mutations of hereditary renal cancers from a radiologist's perspective. Renal manifestations, as well as associated radiological findings and pitfalls are discussed. Additionally, screening and surveillance recommendations are also discussed to aid radiologists in the decision-making process for patient management. PMID- 29571806 TI - Pulmonary nodules: Assessing the imaging biomarkers of malignancy in a "coffee break". AB - INTRODUCTION: Although nodule volumetry is a recognized biomarker of malignancy in pulmonary nodules (PNs), caution is needed in its interpretation because of variables such as respiratory volume variation and inter-scan variability of up to 25%. CT Texture Analysis (CTTA) is a potential independent biomarker of malignancy but inter-scan variability and respiratory volume variation has not been assessed. METHODS: In this prospective cohort study, 40 patients (20 with an indeterminate PN and 20 with pulmonary metastases) underwent two LDCTs within a 60-min period (the "Coffee-break") with the aim of assessing the repeatability of CTTA and semi-automated volume measurements. Texture features were extracted from each automatic contoured region surrounding the PN. Patients were also randomized to two inspiratory control groups: normal breath hold, and controlled lung volume to study the influence of inspiratory control on these measurements. RESULTS: The mean difference in volume between the two scans was 6.3%,SD:29.9%. The textural features displayed 95% CI below +/-17.8%, and were less variable than nodule volume (95%CI +/- 28.9%). All features had high repeatability, calculated by the concordance correlation coefficient, (0.84 <= CCC <= 0.99). All measurements were more repeatable for the controlled lung volume group than the normal breath-hold group. CONCLUSION: CTTA repeatability was comparable to automatic volumetric measurements, and appears to be improved using controlled volume breath holding. PMID- 29571807 TI - Cumulative effective dose and cancer risk for pediatric population in repetitive full spine follow-up imaging: How micro dose is the EOS microdose protocol? AB - OBJECTIVE: To evaluate and to obtain analytic formulation for the calculation of the effective dose and associated cancer risk using the EOS microdose protocol for scoliotic pediatric patients undergoing full spine imaging at different age of exposure; to demonstrate the microdose protocol capable of delivering lesser radiation dose and hence of further reducing cancer risk induction when compared with the EOS low dose protocol; to obtain cumulative effective dose and cancer risk for both genders scoliotic pediatrics of US and Hong Kong population using the microdose protocol. METHODS: Organ absorbed doses of full spine exposed scoliotic pediatric patients have been simulated with the use of EOS microdose protocol imaging parameters input to the Monte Carlo software PCXMC. Gender and age specific effective dose has been calculated with the simulated organ absorbed dose using the ICRP-103 approach. The associated radiation induced cancer risk, expressed as lifetime attributable risk (LAR), has been estimated according to the method introduced in the Biological Effects of Ionizing Radiation VII report. Values of LAR have been estimated for scoliotic patients exposed repetitively during their follow up period at different age for US and Hong Kong population. RESULTS: The effective doses of full spine imaging with simultaneous posteroanterior and lateral projection for patients exposed at the age between 5 and 18 years using the EOS microdose protocol have been calculated within the range of 2.54-14.75 MUSv. The corresponding LAR for US and Hong Kong population was ranged between 0.04 * 10-6 and 0.84 * 10-6. Cumulative effective dose and cancer risk during follow-up period can be estimated using the results and are of information to patients and their parents. CONCLUSION: With the use of computer simulation and analytic formulation, we obtained the cumulative effective dose and cancer risk at any age of exposure for pediatric patients of US and Hong Kong population undergoing repetitive microdose protocol full spine imaging. Girls would be at a statistically significant higher cumulative cancer risk than boys undergoing the same microdose full spine imaging protocol and the same follow-up schedule. PMID- 29571808 TI - Comparison of the effect of radiation exposure from dual-energy CT versus single energy CT on double-strand breaks at CT pulmonary angiography. AB - PURPOSE: To compare the effect of dual-source dual-energy CT versus single-energy CT on DNA double-strand breaks (DSBs) in blood lymphocytes at CT pulmonary angiography (CTPA). METHODS AND MATERIALS: Sixty-two patients underwent either dual-energy CTPA (Group 1: n = 21, 80/Sn140 kVp, 89/38 mAs; Group 2: n = 20, 100/Sn140 kVp, 89/76 mAs) or single-energy CTPA (Group 3: n = 21, 120 kVp, 110 mAs). Blood samples were obtained before and 5 min after CTPA. DSBs were assessed with fluorescence microscopy and Kruskal-Walls tests were used to compare DSBs levels among groups. Volume CT dose index (CTDIvol), dose length product (DLP) and organ radiation dose were compared using ANOVA. RESULTS: There were increased excess DSB foci per lymphocyte 5 min after CTPA examinations in three groups (Group 1: P = .001; Group 2: P = .001; Group 3: P = .006). There were no differences among groups regarding excess DSB foci/cell and percentage of excess DSBs (Group 1, 23%; Group 2, 24%; Group 3, 20%; P = .932). CTDIvol, DLP and organ radiation dose in Group 1 were the lowest among the groups (all P < .001). CONCLUSION: DSB is increased following dual-source and single-source CTPA, while dual-source dual-energy CT protocols do not increase the estimated radiation dose and also do not result in a higher incidence of DNA DSBs in patients undergoing CTPA. PMID- 29571809 TI - Vessel suppressed chest Computed Tomography for semi-automated volumetric measurements of solid pulmonary nodules. AB - OBJECTIVE: To evaluate whether vessel-suppressed computed tomography (VSCT) can be reliably used for semi-automated volumetric measurements of solid pulmonary nodules, as compared to standard CT (SCT) MATERIAL AND METHODS: Ninety-three SCT were elaborated by dedicated software (ClearRead CT, Riverain Technologies, Miamisburg, OH, USA), that allows subtracting vessels from lung parenchyma. Semi automated volumetric measurements of 65 solid nodules were compared between SCT and VSCT. The measurements were repeated by two readers. For each solid nodule, volume measured on SCT by Reader 1 and Reader 2 was averaged and the average volume between readers acted as standard of reference value. Concordance between measurements was assessed using Lin's Concordance Correlation Coefficient (CCC). Limits of agreement (LoA) between readers and CT datasets were evaluated. RESULTS: Standard of reference nodule volume ranged from 13 to 366 mm3. The mean overestimation between readers was 3 mm3 and 2.9 mm3 on SCT and VSCT, respectively. Semi-automated volumetric measurements on VSCT showed substantial agreement with the standard of reference (Lin's CCC = 0.990 for Reader 1; 0.985 for Reader 2). The upper and lower LoA between readers' measurements were (16.3, 22.4 mm3) and (15.5, -21.4 mm3) for SCT and VSCT, respectively. CONCLUSIONS: VSCT datasets are feasible for the measurements of solid nodules, showing an almost perfect concordance between readers and with measurements on SCT. PMID- 29571810 TI - The Unusual Presence of Gas From a Puncture Wound: A Case Report. AB - The presence of gas within soft tissues as suggested by plain film radiographs and magnetic resonance imaging is usually sufficient evidence for a gas-producing bacterial infection. A thorough clinical examination and history and tissue culture are necessary to better determine the source of the gas. However, despite the unremarkable physical examination findings, the present case of a plantar puncture wound rapidly developed gas in the tissues and warranted surgical exploration and repair. Delaying treatment in any case of potential gas gangrene can be limb- and life-threatening. Only later was it revealed by the patient's husband that the wound might have been contaminated soon after the injury from a source other than the puncture, which led to the early presentation of gas on the imaging studies. PMID- 29571811 TI - Spontaneous symmetry breaking of population: Stochastic Lotka-Volterra model for competition among two similar preys and predators. AB - The celebrated Lotka-Volterra (LV) model is vastly used to describe the simple competition between prey and predator populations. The stochastic LV model, for its turn, considers the competition among two similar prey and two similar predator populations, with each group being described by identical mathematical equations. However, each of these groups differs in stochastic fluctuations, which are interpreted as small variations in each species' specimens (Genetic Diversity and Phenotypic Expression Diversity) and environmental conditions. The relative statistical variation presented is inversely proportional to the square root of the amount of specimens in each population. The model begins with two prey and two predator groups and, after a transient time, is reduced to one element of each group, returning to the classic LV system. That is, the model ends in asymmetric states despite starting from an initial symmetric condition without population excess. Spontaneous population symmetry breaking without population excess was obtained using the stochastic method. For its turn, the deterministic method could be used to analyze such breaking by forcing a perturbative fluctuation or adding little excess to one population, but the stochastic method can simulate such break in symmetry naturally. PMID- 29571812 TI - Vitality heterogeneity in the Strehler-Mildvan theory of mortality. AB - In this paper the Strehler-Mildvan theory of mortality and aging is generalised to cover heterogeneity effects in the population. The theory is based on the concept of environmental shocks that cause death of an individual when exceeding its vitality. Heterogeneity is introduced via the value of the vitality of an individual at birth. The main result of the paper is an expression for the observed mortality rate of the heterogeneous population. This mortality rate grows according to Gompertz's Law at midlife-ages, then its growth declines, levelling off at high ages. This behaviour is qualitatively consistent with real mortality rates, which is illustrated for period data of Japanese females in the years 1947, 1967, 1987 and 2007. Finally, the duality between a continuous SM version and the rho - gamma - Gompertz model is discussed. PMID- 29571813 TI - Analysis of the peristaltic-ciliary flow of Johnson-Segalman fluid induced by peristalsis-cilia of the human fallopian tube. AB - The present prospective theoretical analysis concerns with the peristalsis-cilia induced transport of a developing embryo from ampulla to intramural, in the human fallopian tube. A model of peristalsis-cilia induced flow of the Johnson-Segalman fluid within fallopian tubal fluid in a finite two dimensional narrow tube is developed. We solved highly non-linear PDE emerging from the modeling of proposed model using perturbation method. The series expressions for flow variables like axial and radial velocities, pressure gradient, stream function, volume flow rate and time mean volume flow rate are derived. The numerical integration is performed for appropriate residue time over tube length and pressure difference over wavelength. The analysis delineated that, involved parameters and constants have vice versa effects on axial velocity and appropriate residue time over tube length. Striking features of the pumping characteristics and the trapping phenomenon are discussed in detail. Furthermore, comparison of the peristaltic flow with the peristaltic-ciliary flow and Johnson-Segalman fluid with the linearly viscous fluid is made. It is revealed that appropriate residue time of the Johnson-Segalman fluid in the narrow tube is 3-4 days, which agreed with the time taken by the developing embryo from ampulla to intramural, in the human fallopian tube. PMID- 29571814 TI - Modeling the lake eutrophication stochastic ecosystem and the research of its stability. AB - In the reality, the lake system will be disturbed by stochastic factors including the external and internal factors. By adding the additive noise and the multiplicative noise to the right-hand sides of the model equation, the additive stochastic model and the multiplicative stochastic model are established respectively in order to reduce model errors induced by the absence of some physical processes. For both the two kinds of stochastic ecosystems, the authors studied the bifurcation characteristics with the FPK equation and the Lyapunov exponent method based on the Stratonovich-Khasminiskii stochastic average principle. Results show that, for the additive stochastic model, when control parameter (i.e., nutrient loading rate) falls into the interval [0.388644, 0.66003825], there exists bistability for the ecosystem and the additive noise intensities cannot make the bifurcation point drift. In the region of the bistability, the external stochastic disturbance which is one of the main triggers causing the lake eutrophication, may make the ecosystem unstable and induce a transition. When control parameter (nutrient loading rate) falls into the interval (0, 0.388644) and (0.66003825, 1.0), there only exists a stable equilibrium state and the additive noise intensity could not change it. For the multiplicative stochastic model, there exists more complex bifurcation performance and the multiplicative ecosystem will be broken by the multiplicative noise. Also, the multiplicative noise could reduce the extent of the bistable region, ultimately, the bistable region vanishes for sufficiently large noise. What's more, both the nutrient loading rate and the multiplicative noise will make the ecosystem have a regime shift. On the other hand, for the two kinds of stochastic ecosystems, the authors also discussed the evolution of the ecological variable in detail by using the Four-stage Runge-Kutta method of strong order gamma=1.5. The numerical method was found to be capable of effectively explaining the regime shift theory and agreed with the realistic analyze. These conclusions also confirms the two paths for the system to move from one stable state to another proposed by Beisner et al. [3], which may help understand the occurrence mechanism related to the lake eutrophication from the view point of the stochastic model and mathematical analysis. PMID- 29571815 TI - Extracorporeal lithotripsy of salivary gland stone: A 55 patients study. AB - Sialolithiasis are the most frequent salivary gland disease, mainly affecting the submandibular gland. With the advent of minimally invasive techniques, total salivary gland removal should not be considered as the first-line treatment anymore. Extracorporeal Shock Wave Lithotripsy (ESWL) is an alternative to surgery preserving the gland. The objective of our retrospective study was to evaluate the efficiency of ESWL on pain and obstructive syndrome in patients suffering from sialolithiasis. The global result felt by the patients was also considered. All patients treated between October 2009 and July 2016 for sialolithiasis by ESWL in our department were included. They were divided into two groups according to the concerned gland: a parotid gland (PG) and a submandibular gland (SMG) group. Our retrospective telephone questionnaire consisted in 4 questions about their symptomatology before and after ESWL, including pain self-evaluation before and after treatment. They were finally asked to evaluate the global result of the ESWL treatment: excellent, good, mean, or poor. In total, 55 patients were included in this study, 38 patients in PG group and 17 patients in SMG group. We observed a decrease of pain and obstructive syndrom after ESWL procedure in both groups. Better results were found on the obstructive syndrome in the PG group. Very few side-effects were reported by patients. Given that it has very few side effects, ESWL can easily be considered as first line treatment for sialolithiasis to avoid heavier treatments such as surgery. It should be the first-line treatment for symptomatic parotid sialolithiases. The treatment of symptomatic submandibular sialolithiases depends on the topography of the lithiasis. PMID- 29571816 TI - Does mandibular third molar have an impact on dental mandibular anterior crowding? A literature review. AB - Mandibular dental anterior crowding is a common multi-factorial phenomenon. The involvement of the lower third molar remains unclear. These pending questions led us to conduct a literature review to evaluate the impact of the lower third molar on mandibular dental anterior crowding. Twelve articles were selected, published from 1974 to 2014. Four studies were prospective. Sample size ranged from 30 to 9044. The average age was 20.56 years old. Seven studies considered patient with orthodontic treatment. The studies compared two to four groups. Studying tools were radiographs, casts and clinical examinations. Little's irregularity index, TSALD and Ganss ratio were used. In total, 83% of articles (n=10/12) did not find any significant relationship between lower third molar and mandibular dental anterior crowding. However, methods and designs of these studies being questionable, a definite conclusion on the impact of mandibular third molar on mandibular dental anterior crowding cannot be set. PMID- 29571817 TI - Immunogenicity of type 2 monovalent oral and inactivated poliovirus vaccines for type 2 poliovirus outbreak response: an open-label, randomised controlled trial. AB - BACKGROUND: Monovalent type 2 oral poliovirus vaccine (mOPV2) and inactivated poliovirus vaccine (IPV) are used to respond to type 2 poliovirus outbreaks. We aimed to assess the effect of two mOPV2 doses on the type 2 immune response by varying the time interval between mOPV2 doses and IPV co-administration with mOPV2. METHODS: We did a randomised, controlled, parallel, open-label, non inferiority, inequality trial at two study clinics in Dhaka, Bangladesh. Healthy infants aged 6 weeks (42-48 days) at enrolment were randomly assigned (1:1:1:1) to receive two mOPV2 doses (each dose consisting of two drops [0.1 mL in total] of about 105 50% cell culture infectious dose of type 2 Sabin strain) at intervals of 1 week, 2 weeks, 4 weeks (standard or control group), or 4 weeks with IPV (0.5 mL of type 1 [Mahoney, 40 D-antigen units], type 2 [MEF-1, 8 D antigen units], and type 3 [Saukett, 32 D-antigen units]) administered intramuscularly with the first mOPV2 dose. We used block randomisation, randomly selecting blocks of sizes four, eight, 12, or 16 stratified by study sites. We concealed randomisation assignment from staff managing participants in opaque, sequentially numbered, sealed envelopes. Parents and clinic staff were unmasked to assignment after the randomisation envelope was opened. Laboratory staff analysing sera were masked to assignment, but investigators analysing data and assessing outcomes were not. The primary outcome was type 2 immune response measured 4 weeks after mOPV2 administration. The primary modified intention-to treat analysis included participants with testable serum samples before and after vaccination. A non-inferiority margin of 10% and p=0.05 (one-tailed) was used. This trial is registered at ClinicalTrials.gov, number NCT02643368, and is closed to accrual. FINDINGS: Between Dec 7, 2015, and Jan 5, 2016, we randomly assigned 760 infants to receive two mOPV2 doses at intervals of 1 week (n=191), 2 weeks (n=191), 4 weeks (n=188), or 4 weeks plus IPV (n=190). Immune responses after two mOPV2 doses were observed in 161 (93%) of 173 infants with testable serum samples in the 1 week group, 169 (96%) of 177 in the 2 week group, and 176 (97%) of 181 in the 4 week group. 1 week and 2 week intervals between two mOPV2 doses were non inferior to 4 week intervals because the lower bound of the absolute differences in the percentage of immune responses were greater than -10% (-4.2% [90% CI -7.9 to -0.4] in the 1 week group and -1.8% [-5.0 to 1.5] in the 2 week group vs the 4 week group). The immune response elicited by two mOPV2 doses 4 weeks apart was not different when IPV was added to the first dose (176 [97%] of 182 infants with IPV vs 176 [97%] of 181 without IPV; p=1.0). During the trial, two serious adverse events (pneumonia; one [1%] of 186 patients in the 1 week group and one [1%] of 182 in the 4 week group) and no deaths were reported; the adverse events were not attributed to the vaccines. INTERPRETATION: Administration of mOPV2 at short intervals does not interfere with its immunogenicity. The addition of IPV to the first mOPV2 dose did not improve poliovirus type 2 immune response.

PMID- 29571819 TI - Reliability evaluation of inter-eminence line, Akagi and Dalury lines for intraoperative tibial rotation: An osteology-based study. AB - BACKGROUND: This large osteology study examined the reliability, reproducibility and correlation between previously described tibial tray rotation alignment lines (including Akagi and Dalury lines). In addition, it described a novel inter eminence line utilising the tibial plateau inter-condylar eminences as a landmark. METHODS: A total of 214 post-medieval (18-19th centuries) skeletal tibia were examined. The inter/intra-observer variation and correlation between reference lines were measured. RESULTS: Inter-observer reproducibility was excellent and there were no differences between Akagi, Dalury, and inter-eminence lines. Similarly, intra-observer reliability was excellent for Akagi, Dalury, and inter-eminence lines. Qualitative review of tibial inter-condylar eminences suggested that these could be easily identifiable. When taking the medial angle from a medial-lateral reference line, the Akagi line showed a mean of 96.90 degrees (+/-10.27), inter-eminence line 94.52 degrees (+/-12.84), and Dalury line 88.06 degrees (+/-11.75). The angle produced by the Dalury line was significantly different from both the Akagi and inter-eminence lines (P<=0.001). The Akagi line and inter-eminence line showed a strong correlation (r=0.74). The Dalury line showed a weaker correlation with both the Akagi line (r=0.69) and inter-eminence line (r=0.40). CONCLUSION: This study suggested that tibial rotation lines showed excellent intra/inter-observer reliability and reproducibility. The novel and easily drawn inter-eminence line showed strong correlation with the Akagi line and could be used for tibial tray rotational alignment in total knee arthroplasty. PMID- 29571820 TI - Universal screening for foetal growth restriction. AB - Foetal growth restriction (FGR) is a major cause of morbidity and mortality. Clinical methods for identifying women whose pregnancies are affected by FGR do not perform well. Despite this, the current approach to screening includes the clinical assessment of risk and targeted use of ultrasound. Universal screening of women using ultrasound has not been shown to improve outcomes in randomised controlled trials and, when implemented nationally in France, appeared mostly to change outcomes for the worse through the effect of iatrogenic prematurity on false positives. Research is currently focused on the development of screening tests with higher sensitivity and specificity, for example, by combining ultrasound with placental biomarkers. The diagnostic tests employed should be identified through high-quality research that investigates the diagnostic accuracy of the tests, and this will usually involve blinding of the results. Therefore, future trials of screening and intervention will require careful planning. Moreover, if trials are to be powered for perinatal death, large sample sizes will be required. PMID- 29571821 TI - Care of the growth-restricted newborn. AB - With the first 1,000 days of life proving to be a critical window of opportunity for physical and cognitive growth and development, an optimal intrauterine environment is vital. If fetus needs are compromised prenatally, there is an increased risk of intrauterine growth restriction (IUGR), and infants being born premature, low birth weight (LBW), or small-for-gestational age (SGA). Specialized care of these high-risk infants is necessary in terms of preconception interventions, resuscitation, thermoregulation, nutritional support and kangaroo mother care. Significant evidence supports exclusive breastfeeding as the standard of care for feeding SGA, preterm, LBW and very low birth weight infants. Expressed milk or donor milk may also require fortification, to meet higher nutrient needs of these newborns. Future research should address the gap in the literature on specific care of term and preterm IUGR and or SGA infants, and strengthening evidence for human milk bank models and emollient care. PMID- 29571822 TI - Neonatal maternal separation leads to a dampening of inflammation-related mechanical and thermal hypersensitivity in juvenile rats. AB - Early life stress (ELS) constitutes a risk factor for the later development of psychopathological disorders partly displaying pain comorbidity. Since ELS may hence be expected to have an impact on pain processing the present study investigates whether ELS could be a factor of vulnerability or resilience against an enhancement of noxious sensitivity in the framework of inflammatory pain in later life. Rats were exposed to the maternal separation (MS) paradigm, an established ELS model. At adulthood, corticosterone levels and anxiety-related behaviors were evaluated. Subsequently, paw edema, noxious mechanical and thermal sensitivity were measured prior and during an inflammation induced by intraplantar injection of Complete Freunds Adjuvant (CFA). The open field test and the corticosterone measures showed no effect of MS. MS did not change mechanical thresholds prior to inflammation but reduced mechanical hyperalgesia after CFA-injection. MS animals did however present shorter latencies to display nocifensive behaviors compared to controls (CON). Furthermore, in CON but not MS, the repetitive noxious heat testing induced a decrease in reaction latencies. Moreover, MS dampened CFA-induced heat hyperalgesia. Altogether, our results suggest that ELS may have a protective impact on inflammatory pain. PMID- 29571823 TI - Dexmedetomidine promotes the recovery of neurogenesis in aged mouse with postoperative cognitive dysfunction. AB - Recently, growing evidence has demonstrated Dexmedetomidine (Dex) a promising intervene preventing postoperative cognitive decline (POCD) following surgery, which is associated with neuroinflammation leading to neuronal apoptosis and deregulated neurogenesis. Previous studies suggested the anti-inflammation and anti-neuroapoptosis action of Dex. Therefore we hypothesize the promoting neurogenesis of Dex linked to stimulating BDNF and subsequent p-MPAK production in a rat model of POCD. In the present study, the POCD animal model was established by performing an exploratory laparotomy under isoflurane anaesthesia in old rats, utilizing which Dex response is confirmed by behavioural tests. Inflammatory biomarkers as IL-1beta and TNF-alpha, mature neuron percentage measured by doublecortin staining (DCX), promoting factors as brain derived growth factor (BDNF), phosphorylated cAMP response element binding protein (CREB) and proteins of kinase A (PKA), MAPK production as p-P38-MAPK protein express were measured. Herein, we showed that surgery reduced DCX-positive neurons and expression of BDNF representing neurogenesis profoundly. As expected, Dex rescued the associated cognitive impairment and inflammatory changes, as well as up regulated expression of BDNF, PKA, p-CREB/CREB and following p-P38-MAPK regulation. Our results confirmed the protective Dex response and indicated the proneurogenesis role of it as well, suggesting the mechanism of beneficial effects of Dex to prevent POCD.

PMID- 29571824 TI - Dose-dependent reduction in cocaine-induced locomotion by Clozapine-N-Oxide in rats with a history of cocaine self-administration. AB - Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) are novel tools for the dissection of circuitry mediating behavior and neural function. Designer receptors based on the muscarinic M3 and M4 subtypes were designed to be activated by clozapine-N-oxide (CNO), a ligand previously shown to be an inert metabolite of clozapine. However, recent work in rats has shown that CNO is reverse metabolized to its parent compound. Furthermore, CNO administration (5 mg/kg IP) attenuates amphetamine-induced locomotion and the evoked dopamine response that accompanies it. As these systems are routinely used to probe the neurocircuitry underlying cocaine-seeking behavior, here we sought to determine whether CNO would have similar effects on cocaine-induced locomotion in rats with a history of cocaine self-administration. In order for muscarinic-based DREADDs to be utilized for the dissection of circuitry underlying behavioral responses to cocaine, the doses of CNO administered to induce DREADD signaling must themselves have no effect on cocaine-induced behavior. Male Sprague-Dawley rats self administered cocaine (0.35 mg/infusion) for 12 days, followed by 14-21 days of instrumental extinction training. Rats then underwent locomotor testing. CNO (0, 3, or 5 mg/kg) was injected (utilizing a within-subjects design), followed 20 min later by cocaine (10 mg/kg IP). Locomotion was monitored for the following 120 min. We found that the 5, but not the 3 mg/kg, dose of CNO reduced cocaine induced locomotion. Thus, studies utilizing DREAADs to probe cocaine-induced behavior should consider these findings when choosing a dose of CNO and include non-DREADD CNO controls.

PMID- 29571828 TI - Low-dose (2-mSv) computed tomography for suspected appendicitis: Applicability in an emergency department. AB - OBJECTIVES: To document the level of interobserver agreement and compare the diagnostic performances of emergency physicians and radiologists at interpreting low radiation CT images of acute appendicitis in adolescents and young adults. METHODS: One hundred and seven adolescents and young adult patients (aged 15 to 44years) that underwent 2-mSv low-dose CT for suspected acute appendicitis between June and December in 2013 were enrolled in this retrospective study. Three emergency physicians and three radiologists with different experiences of low-dose CT independently reviewed CT images. These six physicians rated the likelihood of acute appendicitis using a 5-point Likert scale. We calculated interobserver agreement and compared the diagnostic performances between emergency physicians and radiologists. And diagnostic confidence was also assessed using the likelihood of acute appendicitis. RESULTS: Acute appendicitis was pathologically confirmed in 42 patients (39%); the remaining 65 patients were considered not to have appendicitis. Fleiss' Kappa for reliability of agreement between emergency physicians and radiologists for the diagnosis of acute appendicitis was 0.720 (95% confidence intervals (CI), 0.685-0.726). Pooled areas under the receiver operating characteristics curve (AUC) for a diagnosis of appendicitis were 0.904 and 0.944 for emergency physicians and radiologists, respectively, and these AUC values were not significantly different (95% confidence interval, -0.087, 0.007; p=0.0855). CONCLUSION: The emergency physicians and radiologists showed good interobserver agreement and comparable diagnostic performances for appendicitis in adolescents and adults using low-dose CT images. Low-dose CT could be a useful tool for the diagnosis of appendicitis by emergency physicians.

PMID- 29571830 TI - Impact of Incidence and Progression of Diabetic Retinopathy on Vision-Specific Functioning. AB - PURPOSE: To investigate the independent impact of the incidence and progression of diabetic retinopathy (DR) on visual functioning (VF). DESIGN: Population-based cohort study. PARTICIPANTS: A total of 518 participants aged 40 to 80 years (baseline visit 2007-2009 and second visit 6 years later, 2013-2015), with diabetes, clinical data, and VF information at both visits. MAIN OUTCOME MEASURES: VF-7 scores, converted to interval-level person measures (in logits) using Rasch analysis. METHODS: Incident DR was defined using the Modified Airlie House classification as "none or minimal" DR at baseline and at least mild nonproliferative DR at follow-up; incident vision-threatening DR (VTDR; severe nonproliferative DR, proliferative DR, and/or clinically significant macular edema) as no VTDR at baseline, and present at follow-up; and DR progression as at least a 1-step worsening in DR at follow-up from mild or worse status at baseline. The longitudinal associations between incident DR, VTDR, and DR progression, as well as change in composite and individual item scores of VF, were assessed using multivariable linear regression models. RESULTS: Of the 518 participants (mean age +/- standard deviation [SD] 59.8+/-9.0 years; 47.7% female), 42 (9.8%), 14 (2.8%), and 32 (42.7%) had incident DR, incident VTDR, and DR progression, respectively, at follow-up. In models adjusting for traditional confounders, persons with incident DR and VTDR had a 13.7% (beta = -0.60; 95% confidence interval [CI], -0.96 to -0.24; P = 0.001) and 23% (beta = -1.00; 95% CI, -1.61 to -0.38; P = 0.001) reduction in mean VF scores at follow-up. Furthermore, individuals with incident DR had similar independent reductions in scores for 7 individual items of the VF-7, whereas those with incident VTDR had the largest reductions for activities like cooking (31%; P = 0.003), reading the newspaper (29.6%; P < 0.001), and seeing street signs (28%, P = 0.001) at follow up. Progression of DR was not independently associated with change in overall VF (beta = -0.18; 95% CI, -1.00, 0.64; P = 0.660). CONCLUSIONS: Incident DR, particularly vision-threatening stages, has a substantial negative impact on people's overall vision-dependent functioning and specific activities such as cooking, seeing street signs, and reading the newspaper. Our findings reinforce the need for strategies to prevent or delay the development of DR.

PMID- 29571832 TI - Clinical Prediction Performance of Glaucoma Progression Using a 2-Dimensional Continuous-Time Hidden Markov Model with Structural and Functional Measurements. AB - PURPOSE: Previously, we introduced a state-based 2-dimensional continuous-time hidden Markov model (2D CT HMM) to model the pattern of detected glaucoma changes using structural and functional information simultaneously. The purpose of this study was to evaluate the detected glaucoma change prediction performance of the model in a real clinical setting using a retrospective longitudinal dataset. DESIGN: Longitudinal, retrospective study. PARTICIPANTS: One hundred thirty-four eyes from 134 participants diagnosed with glaucoma or as glaucoma suspects (average follow-up, 4.4+/-1.2 years; average number of visits, 7.1+/-1.8). METHODS: A 2D CT HMM model was trained using OCT (Cirrus HD-OCT; Zeiss, Dublin, CA) average circumpapillary retinal nerve fiber layer (cRNFL) thickness and visual field index (VFI) or mean deviation (MD; Humphrey Field Analyzer; Zeiss). The model was trained using a subset of the data (107 of 134 eyes [80%]) including all visits except for the last visit, which was used to test the prediction performance (training set). Additionally, the remaining 27 eyes were used for secondary performance testing as an independent group (validation set). The 2D CT HMM predicts 1 of 4 possible detected state changes based on 1 input state. MAIN OUTCOME MEASURES: Prediction accuracy was assessed as the percentage of correct prediction against the patient's actual recorded state. In addition, deviations of the predicted long-term detected change paths from the actual detected change paths were measured. RESULTS: Baseline mean +/- standard deviation age was 61.9+/-11.4 years, VFI was 90.7+/-17.4, MD was -3.50+/-6.04 dB, and cRNFL thickness was 74.9+/-12.2 MUm. The accuracy of detected glaucoma change prediction using the training set was comparable with the validation set (57.0% and 68.0%, respectively). Prediction deviation from the actual detected change path showed stability throughout patient follow-up. CONCLUSIONS: The 2D CT HMM demonstrated promising prediction performance in detecting glaucoma change performance in a simulated clinical setting using an independent cohort. The 2D CT HMM allows information from just 1 visit to predict at least 5 subsequent visits with similar performance. PMID- 29571833 TI - Coffee Consumption and Incident Kidney Disease: Results From the Atherosclerosis Risk in Communities (ARIC) Study. AB - BACKGROUND: Moderate coffee consumption has been suggested to be associated with lower risk for chronic conditions such as diabetes, a major precursor to chronic kidney disease (CKD). However, the association between coffee and CKD has not been fully established. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 14,209 participants aged 45 to 64 years from the Atherosclerosis Risk in Communities (ARIC) Study. PREDICTORS: Coffee consumption (cups per day) was assessed at visits 1 (1987-1989) and 3 (1993-1995) using food frequency questionnaires. OUTCOMES: Incident CKD defined as estimated glomerular filtration rate < 60mL/min/1.73m2 accompanied by >=25% estimated glomerular filtration rate decline, CKD-related hospitalization or death, or end-stage renal disease. RESULTS: There were 3,845 cases of incident CKD over a median of 24 years of follow-up. Men, whites, current smokers, and participants without comorbid conditions were more likely to consume higher amounts of coffee per day. After adjustment for demographic, clinical, and dietary factors, higher categories of coffee consumption were associated with lower risk for incident CKD compared with those who never consumed coffee (HR for <1 cup per day, 0.90 [95% CI, 0.82-0.99]; 1-<2 cups per day, 0.90 [95% CI, 0.82-0.99]; 2-<3 cups per day, 0.87 [95% CI, 0.77-0.97]; and >=3 cups per day, 0.84 [95% CI, 0.75-0.94]). In continuous analysis, for each additional cup of coffee consumed per day, risk for incident CKD was lower by 3% (HR, 0.97; 95% CI, 0.95-0.99; P<0.001). LIMITATIONS: Self reported coffee consumption and observational design. CONCLUSIONS: Participants who drank higher amounts of coffee had lower risk for incident CKD after adjusting for covariates. Coffee consumers may not be at adverse risk for kidney disease. PMID- 29571834 TI - Vaccine Biomarkers: In Search of a Goldilocks Approach.

PMID- 29571838 TI - Multidrug-resistant infections in long-term care facilities: extended-spectrum beta-lactamase-producing Enterobacteriaceae and hypervirulent antibiotic resistant Clostridium difficile. AB - Infections due to multidrug-resistant (MDR) organisms in long-term care facilities (LTCFs) residents constitute a public health concern. This multicenter study investigated the frequency of ESBL-producing pathogens and MDR Clostridium difficile in clinical specimens from LTCF residents in Italy. During October 2014 March 2015, all urine and diarrheic fecal samples from LTCF residents (>=65 years) with suspected urinary tract infection or C. difficile infection, respectively, received for diagnosis by 4 hospital laboratories located in different cities were analyzed. Antibiotic susceptibility testing, characterization of resistance genes, and molecular typing of pathogens were performed. Of 806 urine cultures collected from 626 residents at 44 different LTCFs, 492 were positive for microbial infection. Of these, 158 were positive for at least an ESBL-producing Enterobacteriaceae species (32.1%), with Escherichia coli as the most frequent ESBL pathogen (23.4%) followed by Klebsiella pneumoniae (4.5%). Furthermore, 4 carbapenemase producers (0.8%) (1 E. coli with VIM-1and 3 K. pneumoniae with KPC-3) were detected. The CTX-M-15 type ESBL predominated in both E. coli (71.3%) and K. pneumoniae (77.3%). Most E. coli isolates (82.6%) belonged to the ST131/H30 clone/subclone. For K. pneumoniae, ST307 and ST15 were frequent (31.8% and 22.7%, respectively), but isolates harboring blaKPC-3 belonged to CC258. Of 136 diarrheic fecal samples collected from 111 residents at 26 different LTCFs, 21 (15.4%) were positive for toxigenic C. difficile; of these, 13 (62%) were MDR (resistant to 3 or more antimicrobial agents of different classes). The predominant C. difficile polymerase chain reaction ribotype was 356/607 (42.9%), followed by 018, 449, and 078 (14% each). Public health efforts are needed to contain the diffusion of CTX-M-producing Enterobacteriaceae and MDR C. difficile in LTCF settings. PMID- 29571839 TI - Activity of omadacycline tested against Enterobacteriaceae causing urinary tract infections from a global surveillance program (2014). AB - Omadacycline is an aminomethylcycline with in vitro activity against many gram negative pathogens. Omadacycline and comparators were tested against Enterobacteriaceae from urinary tract infections (UTIs) selected from a 2014 global surveillance program and compared to results of isolates from 2010 surveillance. The omadacycline MIC50/90 for Enterobacteriaceae collected during 2014 was 2/>=8 MUg/mL (1/4 MUg/mL minus Proteus, Providencia, and Morganella spp.). The MIC50/90 for E. coli was 1/2 MUg/mL, similar to that in 2010 (MIC50/90, 0.5/2 MUg/mL). The MICs for 91.7% of Klebsiella spp. isolates in 2014 (89.7%, 2010) were <=4 MUg/mL. In 2010 and 2014, a total of 100.0% and 95.8% of ESBL screen-positive (SP) phenotype E. coli and 73.9% and 75.0% of ESBL SP Klebsiella spp., respectively, exhibited MIC values at <=4 MUg/mL. Omadacycline was active against UTI-causing Enterobacteriaceae isolates from NA and EU. Further study of omadacycline to treat UTIs caused by Enterobacteriaceae may be indicated.

PMID- 29571842 TI - Comparative effects of low-dose versus standard-dose alteplase in ischemic patients with prior stroke and/or diabetes mellitus: The ENCHANTED trial. AB - BACKGROUND AND PURPOSE: History of prior stroke (PS) and diabetes mellitus (DM) are considered relative contraindications to the use of intravenous alteplase in patients with acute ischemic stroke (AIS). We aimed to assess whether a history of PS and DM modified the comparative effects of low- versus standard-dose alteplase in patients who participated in the alteplase-dose arm of the Enhanced Control of Hypertension and Thrombolysis Stroke Study (ENCHANTED). METHODS: Data from an international, multi-center, prospective, randomized, open-label, blinded endpoint trial were used to assess the benefits and risks of low (0.6mg/kg) versus standard-dose (0.9mg/kg) intravenous alteplase in thrombolysis-eligible AIS patients. Logistic regression was used for analysis of patient subgroups defined by history of PS and DM on efficacy and safety outcomes, adjusted for confounding variables. RESULTS: After adjusting for baseline characteristics and management variables over the first seven days in 3288 AIS patients (431 PS, 489 DM, and 157 with both), history of PS and DM were not associated with poor outcome at 90-days: whether defined by modified Rankin scale (mRS) scores 2-6 (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.55-1.32; P=0.476) or mortality (OR 1.25, 95%CI 0.62-2.52; P=0.533). There was no differential effect of low-versus standard-dose alteplase on dichotomized mRS (0-1 vs. 2-6), ordinal shift in mRS scores, mortality, or symptomatic intracerebral hemorrhage, by a history of PS and DM. CONCLUSIONS: A history of PS and DM was not an independent predictor of poor outcome in thrombolysis-treated AIS patients. We were not able to demonstrate any effect of these variables in modifying the differences in effects of low- versus standard-dose alteplase.

METHODS: We defined motor progression as a difference of at least one point in the Hoehn & Yahr (H&Y) scale between the baseline (Visit 0, V0), 12 months (Visit 04, V04) and 36 months (Visit 08, V08) milestones of the Progression Markers Initiative (PPMI) study. H&Y progression events were recorded at each milestone in order to be used as cluster analysis variables, in order to produce progression phenotypes. Subsequently, cross-cluster comparisons prior to and following (pairwise) propensity score matching were performed in order to assess phenotype - defining characteristics. RESULTS: Four progression clusters where identified: SPPD: Secondarily Progressive PD, H&Y progression between V04 and V08; EPPD: Early Progressive PD. H&Y progression between V0 and V04; NPPD: Non Progressive PD, no H&Y progression; MIPD: Minimally Improving PD, i.e. Minimal H&Y improvement H&Y progression between V04 and V08;. Independent Samples Mann Whitney U tests determined CSF aSyn (p = 0.006, adj p-value = 0.036. I) and Semantic Animal fluency T-score (SFT, p = 0.003, adjusted p-value = 0.016.) as statistically significant cross-cluster characteristics. Following Propensity Score Matching, SFT, Hopkins Verbal Learning Test (Retention/Recall), Serum IGF1, CSF aSyn, DaT-SPECT binding ratios (SBRs) and the Benton Judgement of Line Orientation Test (BJLOT) were determined as statistically significant predictors of cluster differentiation (p < 0.05). DISCUSSION: SFT, Serum IGF1, CSF aSyn and DaT-SPECT-derived, basal ganglia Striatal Binding Ratios warrant further investigation as possible motor progression biomarkers.

AB - Sodium MRI (23Na-MRI) has been used to non-invasively quantify tissue sodium but has been limited by low spatial resolution. Here we demonstrate for the first time that high resolution 23Na-MRI reveals the spatial heterogeneity of sodium concentration within a multiple sclerosis (MS) lesion. A patient with treatment naive relapsing-remitting MS and a ring-enhancing lesion was imaged using 23Na MRI. The periphery of the lesion demonstrated an elevated total sodium content compared to the normal appearing white and grey matter (p<0.01), as well as a heterogeneous distribution of both the total tissue sodium concentration and the intracellular-weighted sodium concentration. PMID- 29571846 TI - Neutrophil to lymphocyte ratio and early clinical outcomes in patients with acute ischemic stroke. AB - BACKGROUND: The neutrophil to lymphocyte ratio (NLR) is closely linked to mortality in patients with cardiovascular disease. We investigated whether NLR is associated with early clinical outcomes in patients with acute ischemic stroke. METHODS: We collated data from a tertiary hospital's stroke registry including admitted patients with a first-ever acute ischemic stroke within 72 h of onset. White blood cell counts and peripheral differential counts were measured on admission. Early clinical outcomes were in-hospital mortality and disability at discharge assessed by the modified Rankin scale (mRS). RESULTS: Among 1131 stroke patients, 454 patients were included and classified into tertile groups based on NLR on admission. Patients in higher tertiles of NLR were likely to have severe neurologic deficit at discharge. Higher NLR tertiles were associated with an unfavourable shift of mRS score (p < .0001). This association remained significant after adjustment for clinical and laboratory variables including age, sex, hypertension, hypercholesterolemia, atrial fibrillation, stroke severity, and glucose level (p = .032 for trend). However, risk of death or major disability (score of 3-6 on mRS) and in-hospital mortality were not significantly different across NLR tertile groups. CONCLUSIONS: In patients with acute ischemic stroke, NLR was predictive of short-term functional outcome.

AB - Previous studies have shown that circulating AQP4-IgG may lead to negative consequences during pregnancy in patients with neuromyelitis optica spectrum disorder (NMOSD). The objective of this study was to explore whether AQP4-IgG influences pregnancy by affecting AQP4 expression and inducing placental inflammation in patients with NMOSD. We prospectively collected clinical data from six pregnant AQP4-IgG-seropositive NMOSD patients and their infants, and investigated AQP4 expression and placental inflammatory infiltration by comparing hematoxylin and eosin and immunohistochemical (AQP1, AQP4, C5b-9, IgG, CD3, CD8, CD20, and CD68) staining results with three normal controls. Four patients were term pregnant and their infants were normal for development, serum AQP4-IgG was positive at the time of birth, and three infants were negative for AQP4-IgG after 3 months. Two patients underwent induced abortion; one because of NMOSD relapse and another because of fetal malformation. Histological investigation showed normal structure of the chorionic villi, and no significant difference in the intensity of the immunohistochemical staining for AQP1, AQP4, and inflammatory markers in placentae of patients and the controls. Our results showed that there was no significant decrease in placental AQP4 expression, and no obvious placental inflammation or signs of damage in term placentae of NMOSD patients seropositive for AQP4-IgG. PMID- 29571848 TI - Ischemic stroke due to embolic heart diseases and associated factors in Benin hospital setting. AB - INTRODUCTION: Poor access to cardiovascular checkups is a major cause of ignorance of embolic heart diseases as the etiology for ischemic stroke. OBJECTIVE: Study ischemic strokes due to embolic heart diseases and their associated factors. METHOD: It was a cross-sectional, prospective, descriptive and analytical study conducted from November 1, 2014 to August 31, 2015 on 104 patients with ischemic stroke confirmed through brain imaging. Embolic heart diseases included arrhythmia due to atrial fibrillation (AF), atrial flutter, myocardial infarction (MI), heart valve diseases and atrial septal aneurysm (ASA). The dependent variable was embolic heart disease while independent variables encompassed socio-demographic factors, patients' history, and lifestyle. Data analysis was carried out through SAS 9.3. RESULTS: The rate of embolic heart diseases (EHD) as etiology for ischemic stroke was 26% (28/104). AF accounted for 69% of embolic heart diseases and 22.8% of etiologies for ischemic stroke. Ischemic strokes prevalence was 3.5%, 2.5% and 1.2% respectively for heart valve diseases, MI and ASA. The associated factor was age (p=0.000). CONCLUSION: The diagnosis of a potential cardiac source of embolism is essential because of therapeutic and prognostic implications. Wherefore, there is need for cardiovascular examination particularly Holter ECG and cardiac ultrasound examination which are not always accessible to our populations. PMID- 29571849 TI - Oligoclonal bands and periventricular lesions in multiple sclerosis will not increase blood-brain barrier permeability. AB - OBJECTIVE: To elucidate the etiology and clinical significance of periventricular lesions (PVLs) and oligoclonal bands (OB) in multiple sclerosis (MS). METHODS: We enrolled a total of 97 MS patients (67 OB-positive and 30 OB-negative) who were negative both for anti-aquaporin-4 (AQP4) autoantibody and anti-myelin oligodendrocyte glycoprotein (MOG) antibody. In these patients, comprehensive data including clinical, laboratory, and MRI were collected to investigate the significance of OB and PVLs. RESULTS: Within the MS patients, OB-positivity and the number of PVLs were associated each other. Both of OB-positivity and PVLs did not affect clinical severity or relapse rate, though the patients with >=3 PVLs showed faster cerebral atrophy than those with <3 PVLs. The patients with OB or >=3 PVLs showed lower values of quotient of albumin (QAlb), a biomarker of blood brain barrier (BBB)-permeability and possibly reflects the ongoing disease activity, and lower protein levels in cerebrospinal fluid (CSF). The causal relationship between the decreased QAlb and OB or >=3 PVLs was not determined. CONCLUSIONS: OB and PVLs were associated each other, but they did not affect the clinical course or increased the BBB-permeability within MS patients. PMID- 29571850 TI - Phenotypical features of two patients diagnosed with PHARC syndrome and carriers of a new homozygous mutation in the ABHD12 gene. AB - PHARC (Polyneuropathy, Hearing loss, Ataxia, Retinitis pigmentosa and Cataracts) (MIM# 612674) is an autosomal recessive neurodegenerative disease caused by mutations in the ABHD12 gene. We evaluated two Spanish siblings affected with pes cavus, sensorimotor neuropathy, hearing loss, retinitis pigmentosa and juvenile cataracts in whom the genetic test of ABHD12 revealed a novel homozygous frameshift mutation, c.211_223del (p.Arg71Tyrfs*26). The earliest clinical manifestation in these patients was a demyelinating neuropathy manifested with a Charcot-Marie-Tooth phenotype over three decades. Progressive hearing loss, cataracts and retinitis pigmentosa appeared after the age of 30. We herein describe the complete clinical picture of these two patients, and focus particularly on neuropathy characteristics. This study supports the fact that although PHARC is rare, its phenotype is very characteristic and we should include its study in patients affected with demyelinating polyneuropathy, hearing loss and retinopathy. PMID- 29571851 TI - In a stroke cohort with incident hypertension; are more women than men likely to be excluded from recombinant tissue-type Plasminogen Activator (rtPA)? AB - BACKGROUND: The treatment outcomes in the use of rt-PA have been reported. Some studies reported worse outcome in women than men, while others presented opposing data. Using data from a hospital-based stroke registry, we investigated evidence of gender difference and determined exclusion criteria in a stroke population with incidence of hypertension. METHOD: In a stroke population of women and men with incident of hypertension from a stroke registry, demographics and clinical factors were compared. Univariate analysis was used to determine gender differences, while multivariable models adjusted for demographic and clinical variables. RESULTS: Among the 669 stroke patients with incident of hypertension that were excluded from rt-PA treatment, 362 were female and 307 were male. Female patients with increasing age (OR = 0.956-0.984, P < 0.001), diabetes mellitus (OR = 0.095-0.559, P = 0.001), higher NIH stroke scale score (OR = 1.019 1.090, P = 0.002), previous stroke (OR = 0.337-0.850, P = 0.008), diabetes medication (OR = 1.200-7.724, P = 0.019), and INR (OR = 0.033-0.597, P = 0.008) are more likely to be excluded. Male patients with a history of a previous stroke (OR = 0.265-0.704, P = 0.001), risk of mortality (OR = 0.803-0.950, P = 0.002), higher NIH stroke scale score(OR = 1.101-1.276, P < 0.001), cholesterol reducing medication (OR = 1.191-2.910, P = 0.006), weakness at presentation(OR = 1.207 4.421, P = 0.011), and INR (OR = 0.016-0.243, P < 0.001) are more likely to be excluded. CONCLUSION: Women have a worse outcome than men in an untreated acute ischemic stroke population, but when treated, women have a better treatment outcome compared to men. In a hypertensive stroke population, the clinical variables for the exclusion criteria for women and men are significantly different, even after adjustment for confounding variables. PMID- 29571852 TI - MRI scout images can detect the acute intracerebral hemorrhage on CT. AB - INTRODUCTION: Magnetic resonance imaging (MRI) has recently emerged as a first line tool for investigating acute stroke. However, MRI requires long scan times, which could be detrimental for severe stroke patients with a large intracerebral hemorrhage (ICH). MRI scout images, which are taken prior to a study to determine the range of subsequent images, can be used to rapidly screen the whole brain. We examined whether MRI scout imaging can detect ICHs observed by computed tomography (CT). METHODS: Between September 2014 and March 2016, consecutive acute ICH patients who underwent both MRI scout and CT imaging in the acute setting were studied. ICHs on MRI scout images were defined as space-occupying lesions. Two neurologists independently assessed the scout images. We investigated whether ICHs on CT scans can be detected on MRI scout images and the characteristics of ICHs not detected by MRI scout images. RESULTS: One hundred and forty-eight ICH patients (median age, 68 [interquartile range, 59-77] years; 99 [67%] males; median National Institutes of Health Stroke Scale score, 11 [4 17]) were enrolled. Among these, 138 (93%) patients were diagnosed as having ICH by MRI scout imaging (positive group), and 10 (7%) patients were not (negative group). The bleeding volume was 9.3 [4.5-22.4] ml in the positive group and 1.0 [0.4-2.0] ml in the negative group (p < .001). The cut-off value of bleeding volume calculated from the receiver operating characteristic curve was 2.0 ml. Regarding ICH lesions, 4 (44%) of the 9 pontine hemorrhages were detected on MRI scout images, whereas 134 (96%) of the 139 other hemorrhages were diagnosed (p < .001). CONCLUSIONS: We diagnosed >90% of ICHs using MRI scout images. Low levels of ICH and pontine hemorrhaging might be difficult to detect using MRI scout imaging.

AB - BACKGROUND: Glatiramer acetate (GA) 40 mg * 3/weekly was approved for the treatment of relapsing-remitting multiple sclerosis (RRMS). While the beneficial effect of GA 20 mg/daily in MS patients on non-conventional MRI measures has been demonstrated, the effect of GA 40 mg * 3/weekly at the microstructural tissue level has yet to be explored. OBJECTIVE: To investigate the effect of switching from GA 20 mg/daily to GA 40 mg * 3/weekly on the evolution of microstructural changes in the thalamus and normal appearing white matter (NAWM), using diffusion tensor imaging (DTI). METHODS: In this observational, longitudinal, cross-over, 34-month MRI study, we recruited 150 RRMS patients that underwent MRI 12-18 months before switching (pre-index), during the switch (index) and 12-18 months after switching (post-index) from GA 20 mg/daily to GA 40 mg * 3/weekly. Regional DTI metrics and tract-based spatial statistics (TBSS) analyses were performed. Mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD) and fractional anisotropy (FA) were measured in thalamus and NAWM. RESULTS: Regional DTI measures, measures of whole brain, white and gray matter, and thalamus volumes, as well as lesion volume, showed no significant changes. However, the voxel-wise TBSS analysis showed increased FA both in the NAWM and thalamus, as well as increased MD and AD in NAWM, and decreased RD in NAWM (p < .05). Areas of increased FA and MD as well as decreased RD in the NAWM, and increased AD both in the NAWM and thalamus were detected between index to post-index (p < .05). CONCLUSIONS: This study confirms a comparable effect of GA 40 mg * 3/weekly to GA 20 mg/daily on DTI measures over 34 months. PMID- 29571855 TI - Quantification of whole-body bradykinesia in Parkinson's disease participants using multiple inertial sensors. AB - Bradykinesia (slowness of movement) is a common motor symptom of Parkinson's disease (PD) that can severely affect quality of life for those living with the disease. Assessment and treatment of PD motor symptoms largely depends on clinical scales such as the Unified Parkinson's Disease Rating Scale (UPDRS). However, such clinical scales rely on the visual assessment by a human observer, naturally resulting in inter-rater variability. Although previous studies have developed objective means for measuring bradykinesia in PD patients, their evaluation was restricted by the type of movement and number of joints assessed. These studies failed to provide a more comprehensive, whole-body evaluation capable of measuring multiple joints simultaneously. This study utilizes wearable inertial measurement units (IMUs) to quantify whole-body movements, providing novel bradykinesia indices for walking (WBI) and standing up from a chair (sit-to stand; SBI). The proposed bradykinesia indices include the joint angles at both upper and lower limbs and trunk motion to compute a complete, objective score for whole body bradykinesia. Thirty PD and 11 age-matched healthy control participants were recruited for the study. The participants performed two standard walking tasks that involved multiple body joints in the upper and lower limbs. The WBI and SBI successfully identified differences between control and PD participants. The indices also effectively identified differences within the PD population, distinguishing participants assessed with (ON) and without (OFF) levodopa; the gold-standard of treatment for PD. The goal of this study is to provide health professionals with an objective score for whole body bradykinesia by simultaneously measuring the upper and lower extremities along with truncal movement. This method demonstrates potential to be used in conjunction with current clinical standards for motor symptom assessment, and may also be promising for the remote assessment of PD patients and in cases where experienced clinicians may not be available. In conclusion, the intelligent use of this technology for the measurement of bradykinesia (among other symptoms) has vast implications for optimizing treatment in Parkinson's disease, ultimately leading to an improvement in quality of life. PMID- 29571856 TI - Software updates of OCT segmentation algorithms influence longitudinal assessment of retinal atrophy. AB - OBJECTIVE: To investigate whether there is a systematic difference in peripapillary retinal nerve fiber layer (pRNFL) thickness measurements between subsequent updates of pRNFL segmentation software provided by Heidelberg Spectralis optical coherence tomography (OCT). METHODS: In total, 838 pRNFL scans from 213 multiple sclerosis (MS) patients and 61 healthy controls were analyzed. All scans were performed on the same OCT device followed by automated segmentation (HRA 5.6.4.0) and data extraction. Subsequently, all scans were re segmented with an updated software version (HRA 6.0.7.0). To assess level of agreement between the two algorithms, Bland-Altman Plots were constructed. Paired samples t-test and linear regression analyses were used to investigate for differences in mean thickness and proportional bias respectively. RESULTS: Overall, the updated version showed an overestimation of 0.16MUm [95%CI 0.097 0.23, p<0.001] for the global pRNFL thickness compared to the earlier version. The largest differences were found for the nasal inferior (mean ? 0.29MUm, p<0.001) and temporal inferior (mean ? 0.43MUm, p<0.001) sectors. Inspection of the Bland-Altman Plot revealed that the difference between the two versions could be up to 6MUm for the global mean. There was no proportional bias for the global mean (beta=0.003, p=0.245) nor for any of the separate sectors. CONCLUSION: The data show a significant difference in pRNFL thickness measurements between two subsequent versions of the same segmentation software. Although the mean difference was relatively small, the differences within the individual subject could be considerably higher than the known atrophy rate of 1MUm/year in MS.

PMID- 29571858 TI - Anti-myelin oligodendrocyte glycoprotein (MOG) antibodies in patients with optic neuritis and seizures. AB - We describe four patients who experienced optic neuritis (ON) and seizures and were found to have antibodies to myelin oligodendrocyte glycoprotein (MOG) in serum. The index case was a previously healthy 39-year-old man who developed steroid dependent ON and had a generalized seizure when steroids were tapered. He tested positive for antibodies to MOG. We have reviewed the charts of all 11 anti MOG antibody positive patients in our practice and found that 4 patients, all of whom had experienced one or more episodes of ON, also had a generalized seizure during the course of their illness. In 2 patients - including the index case - seizure occurred during steroid taper and in 2 others at the time of an episode of acute disseminated encephalomyelitis (ADEM). Association of anti-MOG antibodies and relapsing demyelinating disorders of the central nervous system is increasingly recognized. Testing for anti-MOG antibodies should be considered in patients with optic neuritis and seizures, especially in those with who also have a history of ADEM. PMID- 29571859 TI - Plasma citrulline levels are increased in patients with multiple sclerosis. AB - BACKGROUND: Multiple sclerosis is an inflammatory demyelinating disorder of the central nervous system (CNS). Myelin basic protein (MBP), which is one of the main compounds of CNS myelin, appears to be hypercitrullinated in the brain of patients with MS. We hypothesized that MS is associated with an increased release of citrulline from the brain. METHODS: Twenty-five patients with MS, 25 controls without neurological disease (CwND) and 25 subjects with non-MS cerebral white matter lesions were included in this study. Groups were matched for age and gender. Clinical MS disability measures were recorded by means of Expanded Disability Status Scale (EDSS) scores and Multiple Sclerosis Severity Scores (MSSS). Citrulline was assessed in plasma obtained from an antecubital peripheral vein (PV) in all participants. Additional internal jugular vein (IJV) samples were examined in 10 patients with MS and 10 CwND. Twelve patients with MS underwent brain magnetic resonance imaging to determine total brain and T2 fluid attenuated inversion recovery lesion volume. RESULTS: Median [IQR] PV citrulline levels were increased in patients with MS (50.47 [86.61] MUM), as compared to CwND (33.58 [43.65] MUM, P = 0.042) and subjects with non-MS cerebral white matter lesions (32.41 [28.86] MUM, P = 0.006). Citrulline IJV levels and IJV/PV ratios were comparable between patients with MS and CwND. No significant correlations were found between PV citrulline levels and any of the clinical, nor radiological, disease measures. CONCLUSION: PV plasma levels of citrulline are elevated in patients with MS but this does not seem to result from an augmented release from the brain. Increased plasma citrulline may be a promising new biomarker in MS but the origin and significance need to be further elucidated. PMID- 29571860 TI - Is the impact of fatigue related to walking capacity and perceived ability in persons with multiple sclerosis? A multicenter study. AB - BACKGROUND: The relationship between fatigue impact and walking capacity and perceived ability in patients with multiple sclerosis (MS) is inconclusive in the existing literature. A better understanding might guide new treatment avenues for fatigue and/or walking capacity in patients with MS. OBJECTIVE: To investigate the relationship between the subjective impact of fatigue and objective walking capacity as well as subjective walking ability in MS patients. METHODS: A cross sectional multicenter study design was applied. Ambulatory MS patients (n = 189, age: 47.6 +/- 10.5 years; gender: 115/74 women/men; Expanded Disability Status Scale (EDSS): 4.1 +/- 1.8 [range: 0-6.5]) were tested at 11 sites. Objective tests of walking capacity included short walking tests (Timed 25-Foot Walk (T25FW), 10-Metre Walk Test (10mWT) at usual and fastest speed and the timed up and go (TUG)), and long walking tests (2- and 6-Minute Walk Tests (MWT). Subjective walking ability was tested applying the Multiple Sclerosis Walking Scale-12 (MSWS-12). Fatigue impact was measured by the self-reported modified fatigue impact scale (MFIS) consisting of a total score (MFIStotal) and three subscales (MFISphysical, MFIScognitive and MFISpsychosocial). Uni- and multivariate regression analysis were performed to evaluate the relation between walking and fatigue impact. RESULTS: MFIStotal was negatively related with long (6MWT, r = -0.14, p = 0.05) and short composite (TUG, r = -0.22, p = 0.003) walking measures. MFISphysical showed a significant albeit weak relationship to walking speed in all walking capacity tests (r = -0.22 to -0.33, p < .0001), which persisted in the multivariate linear regression analysis. Subjective walking ability (MSWS-12) was related to MFIStotal (r = 0.49, p < 0.0001), as well as to all other subscales of MFIS (r = 0.24-0.63, p < 0.001), showing stronger relationships than objective measures of walking. CONCLUSIONS: The physical impact of fatigue is weakly related to objective walking capacity, while general, physical, cognitive and psychosocial fatigue impact are weakly to moderately related to subjective walking ability, when analysed in a large heterogeneous sample of MS patients. PMID- 29571861 TI - A diagnostic decision tree for adult cerebellar ataxia based on pontine magnetic resonance imaging. AB - Cerebellar ataxias (CAs) are heterogeneous conditions often require differential diagnosis. This study aimed to establish a diagnostic decision tree for differentiating CAs based on pontine MRI findings. Two-hundred and two consecutive ataxia patients were clinically classified into 4 groups: (1) spinocerebellar ataxia (SCA) with brainstem involvement (SCA-BSI), (2) Pure cerebellar SCA, (3) cerebellar dominant multiple system atrophy (MSA-c), and (4) Other CA. Signal intensity in pons was graded into 3 types: hot cross bun sign (HCBS), pontine midline linear T2-hyperintensity (PMH), or normal. The distance ratio of pontine base to tegmentum, named "BT-ratio", was measured. The presence of HCBS indicated either MSA-c with a specificity of 97.7%, or SCA2. When PMH was observed, a BT-ratio above 3.54 strongly indicated SCA-BSI, namely Machado-Joseph disease, SCA1, or dentatorubral-pallidoluysian atrophy, whereas a BT-ratio below 3.54 indicated MSA-c or SCA2. When the signal intensity was normal, a BT-ratio above 3.52 indicated SCA-BSI, whereas a BT-ratio below 3.52 suggested Pure cerebellar SCA or Other CA with pure cerebellar type. The decision tree was confirmed useful in a different 30 CA patients. We propose that differential diagnosis of CAs can be supported by combining pontine MRI signal intensity changes and BT-ratio. PMID- 29571862 TI - Emergent carotid artery stenting in atherosclerotic disease of the internal carotid artery with tandem intracranial occlusion. AB - BACKGROUND: Several randomized clinical trials have proven the safety and efficacy of mechanical thrombectomy (MT) in large vessel occlusions; nonetheless, there is still no consensus concerning hyperacute management of tandem occlusions. Recent studies have suggested that emergent carotid artery stenting (eCAS), along with mechanical thrombectomy, is an effective and safe treatment option. AIMS: To characterize the safety and short-term outcome of patients treated with eCAS during endovascular treatment of acute ischaemic stroke. METHODS: Review of the prospective patient registry submitted to MT for anterior circulation acute ischaemic stroke in a single referral centre and selection of patients treated with eCAS for atherosclerotic occlusion or near-occlusion of cervical internal carotid artery during 22 consecutive months. Clinical data was collected, and assessment of procedure safety and 3-month-outcome were performed. RESULTS: Among 156 patients submitted to MT, 16 patients (10.3%) underwent eCAS. Most patients were male (15/16), median age was 64.5 years (interquartile range [IQR] = 57-75), median admission NIHSS was 14 (IQR = 11.5-19) and 10/16 patients had been submitted to intravenous thrombolysis. Successful recanalization was obtained in 93.8% of the patients. One patient (6.3%) experienced symptomatic intracranial haemorrhage, one patient experienced early intra-stent thrombosis and one patient developed cerebral hyperperfusion syndrome. At 3-month follow-up, 11 patients were independent (68.8%) and 1 patient had died (6.3%). CONCLUSIONS: In this study, positive results were obtained using eCAS. Although an optimal intervention for this type of occlusions has not yet been formally established, eCAS has been surging has a feasible and safe treatment option. PMID- 29571864 TI - Radiation-induced meningiomas: A case-control study at single center institution. AB - BACKGROUND: Our understanding of radiation induced meningiomas (RIM) is limited. It has been suggested that RIM harbor more aggressive cellular pathology and must be observed vigilantly. However, the actual recurrence rates of RIM compared to the sporadic meningiomas has yet to be defined. OBJECTIVE: We employ a single center case-control study to retrospectively assess recurrence rates between RIM (n = 12) and sporadic meningiomas (n = 118). METHODS: The criteria for the RIM group included the following: 1) History of intracranial clinical-dose radiation 2) Initial pathology other than meningioma, 3) Radiation administered greater than 5 years prior to meningioma onset. Recurrence rates, extent of resection and outcomes were analyzed. RESULTS: There was a significant difference in recurrence rates between the RIM group and sporadic meningioma: 50% vs. 5% respectively, p = 0.004. There was no significant difference in race, preoperative tumor volume, extent of resection, Ki67, or age between the two groups. Multivariate analysis demonstrated that size (OR 0.95 95%CI (0.92-0.99)), extent of resection (OR 1.08 95%CI (1.01-1.14)), WHO grade (OR 160.24 95% CI (6.32-74509)) and history of previous radiation (OR 1.28 95%CI (1.01-1.62)) were independent risk factors for recurrence. RIM patients had significantly higher proportion of atypical or malignant histology compared to sporadic patients (p < 0.0001). CONCLUSION: RIM patients may have a higher predisposition for tumor recurrence than patients with sporadic RIM. The use of Ki67 indices may help identify patients with a higher risk of tumor recurrence. Prospective studies focusing on newly diagnosed patients with RIM may help identify an optimal surveillance and treatment plan. PMID- 29571863 TI - The new Mobile Universal Lexicon Evaluation System (MULES): A test of rapid picture naming for concussion sized for the sidelines. AB - OBJECTIVE: Measures of rapid automatized naming (RAN) have been used for over 50 years to capture vision-based aspects of cognition. The Mobile Universal Lexicon Evaluation System (MULES) is a test of rapid picture naming under investigation for detection of concussion and other neurological disorders. MULES was designed as a series of 54 grouped color photographs (fruits, random objects, animals) that integrates saccades, color perception and contextual object identification. Recent changes to the MULES test have been made to improve ease of use on the athletic sidelines. Originally an 11 * 17-inch single-sided paper, the test has been reduced to a laminated 8.5 * 11-inch double-sided version. We identified performance changes associated with transition to the new, MULES, now sized for the sidelines, and examined MULES on the sideline for sports-related concussion. METHODS: We administered the new laminated MULES to a group of adult office volunteers as well as youth and collegiate athletes during pre-season baseline testing. Athletes with concussion underwent sideline testing after injury. Time scores for the new laminated MULES were compared to those for the larger version (big MULES). RESULTS: Among 501 athletes and office volunteers (age 16 +/- 7 years, range 6-59, 29% female), average test times at baseline were 44.4 +/- 14.4 s for the new laminated MULES (n = 196) and 46.5 +/- 16.3 s for big MULES (n = 248). Both versions were completed by 57 participants, with excellent agreement (p < 0.001, linear regression, accounting for age). Age was a predictor of test times for both MULES versions, with longer times noted for younger participants (p < 0.001). Among 6 athletes with concussion thus far during the fall sports season (median age 15 years, range 11-21) all showed worsening of MULES scores from pre-season baseline (median 4.0 s, range 2.1-16.4). CONCLUSION: The MULES test has been converted to an 11 * 8.5-inch laminated version, with excellent agreement between versions across age groups. Feasibly administered at pre-season and in an office setting, the MULES test shows preliminary evidence of capacity to identify athletes with sports-related concussion. PMID- 29571865 TI - Preoperative biomarkers in patients with idiopathic normal pressure hydrocephalus showing a favorable shunt surgery outcome. AB - INTRODUCTION: Idiopathic normal pressure hydrocephalus (INPH) is known to be a potentially treatable neurologic condition. The neurocognitive outcomes after surgery, however, have been variable. It is important to define preoperative characteristics of patients that predicts the shunting outcome. We aimed to compare baseline differences between shunt-responsive and unresponsive patients after 1year from surgery in order to identify preoperative predictors showing favorable clinical outcomes. METHODS: Among 69 candidates, 31 patients with probable INPH completed the study. Patients were divided into two groups, responsive group (n=17) and unresponsive group (n=14), according to the clinical outcomes on INPH grading scale and modified Rankin score (MRS). Preoperative cerebrospinal (CSF) Abeta, tau levels, MRI findings, and clinical characteristics were compared between the groups. Correlations between shunt responsiveness and preoperative characteristics were also assessed. RESULTS: After 1year from shunt, gait problem was the most likely to improve. Shunt-responsive group showed lower CSF p-tau/Abeta, fewer lacunes, and higher incidence of disproportionately enlarged subarachnoid space (DESH) signs on MRIs compared to those in unresponsive group. Favorable outcome was related with positive DESH sign and fewer lacunes. CONCLUSIONS: Our results suggest that biomarkers representing non INPH related pathology including Alzheimer's disease and small vessel disease might show less favorable clinical outcomes after 1year from surgery. PMID- 29571866 TI - DAPK1-ERK signal mediates oxygen glucose deprivation reperfusion induced apoptosis in mouse N2a cells. AB - AIMS: Death-associated protein kinase 1 (DAPK1) is a kinase found to promote neuronal apoptosis induced by ischemia. Extracellular signal-regulated kinase (ERK) was identified as a key molecule in DAPK1 signaling. However, the mechanisms of neuronal ischemia reperfusion injury remain unknown. Here, we investigate the influence of DAPK1-ERK signal on neuronal apoptosis following ischemia reperfusion. METHODS: Mouse N2a cells were used in this study and primary cultured neurons along with mice were adopted as supplements. Oxygen glucose deprivation (OGD) or administration of N-methyl-d-aspartate (NMDA) and glycine was performed on cells while middle cerebral artery occlusion (MCAO) model on mice. DAPK1 knocking down was achieved by lentiviral-delivered shRNA. Protein expressions were evaluated by western blots. Protein-protein binding was confirmed by co-immunoprecipitation and immunofluorescent assay. Apoptosis of cells was measured by flow cytometry and lacate dehydrogenase (LDH) leakage assay. RESULTS: Ischemia reperfusion resulted in increased DAPK1 and ERK activation as well as aggravated apoptosis in a time-dependent manner. DAPK1 was proved to bind to ERK during reperfusion following OGD, MCAO and excitotoxicity model. Interception of this binding by knocking down DAPK1 led to nuclear translocation of ERK and reduced apoptosis. CONCLUSION: Our study revealed the DAPK1-ERK signal as a potential mechanism contributing to neuronal apoptosis in response to ischemia reperfusion. Disruption of this signal pathway could be a promising therapeutic target against stroke. PMID- 29571867 TI - Excessive daytime sleepiness may be associated with caudate denervation in Parkinson disease. AB - Excessive daytime sleepiness (EDS) is one of the earliest and most common non motor symptoms of PD, substantially impacting on patient's quality of life. Using the Parkinson's Progression Markers Initiative database, we performed a case control study to investigate whether dopaminergic deficit is associated with the development of EDS using dopaminergic specific single photon emission computed tomography (SPECT) molecular imaging of dopamine transporters (DAT). We enrolled 84 early de novo PD patients with EDS and 84 without EDS, who were matched for age, gender, age of diagnosis, years of education and disease duration. We assessed and compared semi-quantified [123I]FP-CIT SPECT, and motor and non-motor features among these two groups, alongside exploring the clinical and imaging correlates of EDS and the predictive significance of these markers in the development of EDS. PD patients with EDS had worse non-motor (MDS-UPDRS Part-I, P < 0.001) and motor (MDS-UPRDS Part-II, P = 0.005) experiences of daily living, as well as worse autonomic (SCOPA-AUT, P < 0.0001) and cognitive (MoCA P = 0.05) function, depression (GDS, P = 0.002), and reduced caudate DAT ([123I]FP-CIT, P = 0.024) compared to PD patients without EDS. Lower caudate [123I]FP-CIT values correlated with higher EDS scores (r = -0.192, P = 0.013). Among patients without EDS, 47 PD patients (56%) developed EDS over a median follow-up of 36 months. Cox multivariate analysis, including all clinical and imaging data available, revealed that abnormal caudate [123I]FP-CIT uptake (P = 0.030) and disease duration (P = 0.018) were predictors for the development of EDS. Although our findings indicate that dopaminergic deficits in the caudate may be associated to EDS in patients with PD, the pathophysiological causality is debateable, given that dopamine caudate denervation may covary with dopaminergic involvement at other targets and with non-dopaminergic involvement. PMID- 29571868 TI - Neuromuscular diseases associated with Human Immunodeficiency Virus infection. AB - From the most common distal symmetric polyneuropathy (Bilgrami and O'Keefe, 2014) to the rare motor neuron diseases, HIV infection is associated with pathology at all levels of the peripheral nervous system. HIV infection can cause these conditions due to viral exposure itself, the resulting immune dysregulation, opportunistic infections found in untreated patients, and from the therapy used in treatment of the virus. Before the advent of antiretroviral therapy, 5 neuromuscular diseases associated with HIV often resulted from opportunistic infections. With advances in antiretroviral therapy, the etiologies of neuromuscular complications more frequently become the result of prolonged HIV exposure, comorbid diseases, and side effects of medications. In this article we review the literature on HIV associated neuromuscular diseases, emphasizing the more recent studies in the post antiretroviral era, but also reviewing conditions more prevalent in the pre antiretroviral era which continue to be seen in developing countries and resource poor areas. This discussion includes the following conditions: distal symmetric polyneuropathy, autonomic neuropathy, inflammatory demyelinating polyneuropathy, mononeuropathy, mononeuropathy multiplex, polyradiculopathies, myelopathy, myopathy, motor neuron disease, and antiretroviral treatment related conditions. PMID- 29571869 TI - Prevalence of functional (psychogenic) parkinsonism in two Swiss movement disorders clinics and review of the literature. AB - BACKGROUND: Functional parkinsonism (FP) is considered rare but no studies have looked at its frequency. Case series have described high rates of comorbidity with Parkinson's disease (PD), suggesting a possible association between these conditions. OBJECTIVES: To study the prevalence, epidemiology and clinical features of FP and its association with PD. METHODS: We conducted a cross sectional population-based prevalence study as well as a chart review of cases who received a diagnosis of FP over a 10-year-period in two movement disorder clinics in Switzerland. Epidemiological data regarding FP features were collected. The co-occurrence of PD, psychiatric disorders and other functional disorders were recorded. Clinical differences between FP and FP+PD groups are presented and discussed in light of a literature review. RESULTS: The crude prevalence of FP was 0.64 per 100,000 in our population. FP represented 0.24% of patients with parkinsonism. Among 12 FP cases, female gender predominance (87%), mean age of onset of 45.5(+/-13.3 Standard deviation SD) years and prolonged diagnostic delay (mean 59+/-75 SD months) was found. Six patients had an additional diagnosis of PD, 83% of depression and 66% of other functional neurological disorder. In four patients with FP+PD, FP preceded PD by 6 to 56months. CONCLUSIONS: These results suggest that FP should be considered in the differential diagnosis of patients presenting with parkinsonism. The high rate of co-occurrence with PD emphasizes the importance of long-term follow up of these patients. The observation that FP often precedes PD should be verified in prospective studies. PMID- 29571870 TI - Characteristics of the ischemic stroke patients whose seizures occur at stroke presentation at a single institution in Eastern China. AB - PURPOSE: We compared clinical characteristics and outcomes of the early-onset seizure post-stroke patients who had seizures occurring at stroke presentation (SSP) with other patients without SSP at a single institution in Eastern China. METHODS: We reviewed 20,947 ischemic stroke patients in our hospital electronic medical records system from January 2007 to December 2016. Among them, there were 91 (0.43%) patients with early-onset seizure post-stroke. Among these 91 patients, there were 35 (0.16%) SSP patients and another 56 (0.27%) were designated as non SSP patients because they also had early-onset seizure post stroke, but without SSP. We compared the clinical presentations of the SSP patients with those of the non SSP patients including baseline stroke risk factors, and 10-year Kaplan-Meier death risk after their first stroke. RESULTS: In the SSP patients, 25.7% of them presented with posterior circulation infarction, whereas only 12.5% of the non SSP patients had this condition (P<0.05). In contrast, 17.1% of the SSP patients were being treated with antiepileptic drugs at discharge whereas 37.5% of the non SSP patients received such treatment (P<0.05). The percentage of SSP patients with temporal lobe lesions was less than in non SSP patients (P<0.05). However, brain stem and thalamus lesions were more frequently seen in SSP patients than non in SSP patients (P<0.05). The risk factors for ischemic stroke including a history of hypertension, diabetes mellitus, hyperlipidemia and atrial fibrillation were the same in these two groups (P>0.05). In the SSP patients group, the 10-year risk of death was 36.9% after the initial seizure incident, and in the non SSP patients group, the 10-year death risk was 40.1%, but this difference between the two groups was not significant (P>0.05). CONCLUSIONS: Ischemic stroke patients with SSP had some unique signs that included a higher incidence of posterior circulation infarction than non SSP patients.

AB - INTRODUCTION: Freezing of gait (FOG) is a serious complication in patients with Parkinson's disease (PD), and is more common in the late state of the disease. The high risk of falling in patients with FOG impacts their quality of life. OBJECTIVE: To explore altered neuroactivity related to cognitive and executive function of PD patients with FOG. METHODS: Fourteen PD patients with FOG (FOG+), 20 PD patients without FOG (FOG-), and 18 normal controls (NC) were enrolled. Functional MRI data of all PD patients were collected during OFF medication state. Data were analyzed using software of DPARSF and REST. Resting brain activity was measured by regional homogeneity (ReHo). ANOVA test was performed for ReHo among FOG, PD, and NC groups. RESULTS: ReHo alterations of left supplementary motor area (SMA) (Brodmann 6), left superior frontal region (Brodmann 9), and the right putamen (Brodmann 48) were significantly different among the three groups. The ReHo values within left SMA (Brodmann 6) and left superior frontal region (Brodmann 9) were significantly decreased in FOG+ patients compared with FOG- patients. CONCLUSION: Changes in neural hypoactivity within the frontal region and SMA appear to be associated with FOG in PD patients, which suggests that the mechanism underlying FOG may relate to disruption of execution and cognition. PMID- 29571873 TI - Transplantation of in vitro cultured endothelial progenitor cells repairs the blood-brain barrier and improves cognitive function of APP/PS1 transgenic AD mice. AB - To date, the pathogenesis of Alzheimer's disease (AD) remains unclear. It is well known that excessive deposition of Abeta in the brain is a crucial part of the pathogenesis of AD. In recent years, the AD neurovascular unit hypothesis has attracted much attention. Impairment of the blood-brain barrier (BBB) leads to abnormal amyloid-beta (Abeta) transport, and chronic cerebral hypoperfusion causes Abeta deposition throughout the onset and progression of AD. Endothelial progenitor cells (EPCs) are the universal cells for repairing blood vessels. Our previous studies have shown that a reduced number of EPCs in the peripheral blood results in cerebral vascular repair disorder, cerebral hypoperfusion and neurodegeneration, which might be related to the cognitive dysfunction of AD patients. This study was designed to confirm whether EPCs transplantation could repair the blood-brain barrier, stimulate angiogenesis and reduce Abeta deposition in AD. The expression of ZO-1, Occludin and Claudin-5 was up-regulated in APP/PS1 transgenic mice after hippocampal transplantation of EPCs. Consistent with previous studies, EPC transplants also increased the microvessel density. We observed that Abeta senile plaque deposition was decreased and hippocampal cell apoptosis was reduced after EPCs transplantation. The Morris water maze test showed that spatial learning and memory functions were significantly improved in mice transplanted with EPCs. Consequently, EPCs could up-regulate the expression of tight junction proteins, repair BBB tight junction function, stimulate angiogenesis, promote Abeta clearance, and decrease neuronal loss, ultimately improve cognitive function. Taken together, these data demonstrate EPCs may play an important role in the therapeutic implications for vascular dysfunction in AD. PMID- 29571874 TI - Identification and treatment of the visual processing asymmetry in MS patients with optic neuritis: The Pulfrich phenomenon. AB - BACKGROUND: The Pulfrich phenomenon (PF) is the illusory perception that an object moving linearly along a 2-D plane appears to instead follow an elliptical 3-D trajectory, a consequence of inter-eye asymmetry in the timing of visual object identification in the visual cortex; with optic neuritis as a common etiology. OBJECTIVE: We have designed an objective method to identify the presence and magnitude of the PF, in conjunction with a cooresponding strategy by which to abolish the effect; with monocular application of neutral density filters to the less affected fellow eye, in patients with MS and a history of optic neuropathy (e.g. related to acute optic neuritis or subclinical optic neuropathy). METHODS: Twenty-three MS patients with a history of acute unilateral or bilateral optic neuritis, and ten healthy control subjects (HC) were recruited to participate in a pilot study to assess our strategy. Subjects were asked to indicate whether a linearly moving pendulum ball followed a linear 2-D path versus an illusory 3-D elliptical object-motion trajectory, by reporting the ball's approximation to one of nine horizontally-oriented colored wires that were positioned parallel to one another and horizontal to the linear pendulum path. Perceived motion of the bob that moved along wires behind or in front (along the 'Z' plane) of the middle reference wire indicated an illusory elliptical trajectory of ball motion consistent with the PF. RESULTS: When the neutral density filter titration was applied to the fellow eye the severity of the PF decreased, eventually being fully abolished in all but one patient. The magnitude of neutral density filtering required correlated to the severity of the patient's initial PF magnitude (p < 0.001). CONCLUSIONS: We ascertained the magnitude of the visual illusion associated with the PF, and the corresponding magnitude of neutral density filtering necessary to abolish it. PMID- 29571875 TI - Familial and sporadic chronic progressive degenerative parietal ataxia. AB - BACKGROUND & OBJECTIVE: Parietal ataxia has been mainly reported as a consequence of acute ischemic stroke, while degenerative parietal ataxia has not been reported. METHODS: We investigated clinical characteristics, neuroimaging data, and genetic analysis of patients with cerebellar ataxia plus parietal atrophy. RESULTS: We identified seven patients, including five patients from two families, with chronic progressive cerebellar ataxia due to degenerative parietal atrophy but not stroke. Age at onset of ataxia was 57.6 +/- 6.9 years. All patients showed chronic progressive cerebellar ataxia with severity of ataxic gait > limb ataxia > dysarthria. Patients showed no cognitive dysfunction, muscle weakness, or parkinsonism, and only two patients showed mild sensory disturbances. The seven patients showed lateralized limb ataxia with greater contralateral parietal lobe atrophy by magnetic resonance imaging, and hypoperfusion by single photon emission computed tomography, without any abnormal cerebellar pathology (i.e., crossed cerebellar diaschisis). Pathogenic mutations in the microtubule associated protein tau gene were not found using two single nucleotide polymorphisms. CONCLUSIONS: This is the first description showing unique clinical features of familial and sporadic chronic progressive degenerative parietal ataxia. PMID- 29571876 TI - Normal tendon reflexes despite absent sensory nerve action potentials in CANVAS: a neurophysiological study. AB - CANVAS is a recently defined progressive ataxic syndrome with impairment of vestibular, somatosensory and cerebellar function due to atrophic degeneration of dorsal root ganglia and dorsal columns, of cranial nerve somatosensory ganglia, of vestibular ganglia and vestibular nerves and of cerebellar Purkinje cells. While all patients eventually develop sensory impairment in a non-length dependent pattern and lose sensory nerve action potentials, some retain their tendon reflexes. Here we study 5 CANVAS patients with absent sensory nerve action potentials but intact, even brisk Achilles tendon reflexes and, in 4, preserved H reflexes in the upper and lower limbs. These findings imply that dorsal root ganglion neurons subserving cutaneous afferents more vulnerable than those subserving muscle afferents. Our findings have a clinical message: preservation of the Achilles tendon jerk does not exclude a large fibre peripheral neuronopathy. PMID- 29571877 TI - 'The shock of diagnosis': Qualitative accounts from people with Motor Neurone Disease reflecting the need for more person-centred care. AB - The diagnosis of Motor Neurone Disease (MND) is devastating for people with MND (PwMND) and their families. The objective of this study is to describe the experiences of PwMND in receiving the diagnosis in order to inform a more person centred approach to communicating such bad news. The design was an anonymous postal survey facilitated by all MND associations across Australia (2014-15). Survey questions centred on the SPIKES protocol for communicating bad news; each question contained an area for written responses, which were thematically analysed for content. Two hundred and forty-eight responses were received from people with MND (29% response rate). Four themes emerged: challenges in being diagnosed with MND; the emotions experienced; the good and the bad; and links to further information and support. Receiving such a diagnosis requires preparation, forethought, sensitive and individualised care on the part of the neurologist, including where and how the diagnosis is given; the supports required; and timing, amounts and sources of giving information. The emotional reactions of the neurologist also caused a lasting impression on those receiving the diagnosis. This study could form the basis for best practice programs implementing a more person-centred approach to caring for PwMND right from the diagnosis stage. The focus needs to shift on the person's values, preferences, psychosocial and existential concerns in the context of the underlying disease experience and the manner clinical practice is delivered. PMID- 29571878 TI - Expression analysis of protein homeostasis pathways in the peripheral blood mononuclear cells of sporadic amyotrophic lateral sclerosis patients. AB - Misfolded protein aggregates are the hallmark of Amyotrophic Lateral Sclerosis (ALS) which suggests involvement of protein homeostasis pathways in etiology of ALS. However, status of protein homeostasis in peripheral blood of ALS is not well established. We analyzed expression levels of key genes of proteostasis pathways in peripheral blood mononuclear cells (PBMCs) of sporadic ALS (sALS) patients and healthy controls. Increased protein carbonylation was observed in patients reflecting oxidative damage in PBMCs. We observed increased transcript and protein levels of GRP78 suggesting Endoplasmic reticulum (ER) insult to cells. Further, significant upregulation of spliced XBP1 and two stress sensors: IRE1alpha/ERN1 and ATF6 indicated induction of unfolded protein response (UPR). Genes involved in autophagosome initiation (ULK1, ULK2, ATG13); nucleation and elongation (BECLIN1, ATG7, ATG16L1, ATG5, ATG10) and vesicular trafficking genes were significantly increased in patients. Increased lipidation of LC3 validated induction of autophagy. Accumulation of low molecular weight ubiquitinated proteins in patients suggested deregulation of proteasome (UPS) pathway. In addition, cytosolic chaperones (HSP70 and HSP27) and HSF1 were elevated in patients. Increased TDP43 indicated role of TDP43 in disease pathology. Our findings suggest that there is oxidative insult and upregulation of UPR, vesicular trafficking and autophagy in PBMCs of sALS patients.

PMID- 29571880 TI - Pilot trial of a tele-rehab intervention to improve outcomes after stroke in Ghana: A feasibility and user satisfaction study. AB - BACKGROUND: Tele-rehabilitation after stroke holds promise for under-resourced settings, especially sub-Saharan Africa (SSA), with its immense stroke burden and severely limited physical therapy services. OBJECTIVE: To preliminarily assess the feasibility and outcomes of mobile technology-assisted physical therapy exercises for stroke survivors in Ghana. METHODS: We conducted a prospective, single arm, pre-post study involving 20 stroke survivors recruited from a tertiary medical center, who received a Smartphone with the 9zest Stroke App(r) to deliver individualized, goal-targeted 5-days-a-week exercise program that was remotely supervised by a tele-therapist for 12 weeks. Outcome measures included changes in stroke levity scale scores (SLS), Modified Rankin score (MRS), Montreal Cognitive Assessment (MOCA), and feasibility indicators. RESULTS: Among study participants, mean +/- SD age was 54.6 +/- 10.2 years, 11 (55%) were men, average time from stroke onset was 6 months. No participants dropped out. Compared with baseline status, mean +/- SD scores on SLS improved from 7.5 +/- 3.1 to 11.8 +/- 2.2 at month 1 (p < 0.0001) and 12.2 +/- 2.4 at month 3 (p < 0.0001), MOCA scores improved from 18.2 +/- 4.3 to 20.4 +/- 4.7 at month 1 (p = 0.14), and 22.2 +/- 7.6 at month 3 (p = 0.047). Mean +/- SD weekly sessions performed by participants per month was 5.7 +/- 5.8 and duration of sessions was 25.5 +/- 16.2 min. Erratic internet connectivity negatively affected full compliance with the intervention, although satisfaction ratings by study participants were excellent. CONCLUSION: It is feasible to administer an m-health delivered physical therapy intervention in SSA, with high user satisfaction. Randomized trials to assess the efficacy and cost-effectiveness of this intervention are warranted. PMID- 29571881 TI - Neutrophil-to-lymphocyte ratio improves outcome prediction of acute intracerebral hemorrhage. AB - BACKGROUND: The inflammatory response plays a role in determining the course of intra-cerebral hemorrhage (ICH) and immune parameters may have prognostic value. The aim of the study was to determine whether the peripheral leukocyte counts and neutrophil-to-lymphocyte ratio (NLR) were associated to 30-day functional status after ICH, and improved the accuracy of outcome prediction when added to the Modified ICH score. METHODS: We retrospectively identified consecutive patients with spontaneous ICH who underwent blood sampling and cranial CT neuroimaging within 24 h from onset. Total white blood cells (WBC), absolute neutrophil count (ANC) and absolute lymphocyte count (ALC) were collected, and the NLR computed as the ANC to ALC ratio. The study endpoint was 30-day functional status; poor outcome was defined as death or major disability (modified Rankin Scale score >= 3). RESULTS: Two hundred and eight patients were enrolled, of which 111 (53.4%) had a modified Rankin Scale score >= 3 at 30 days from ICH. At multivariate analysis, the WBC (adjusted odd ratio [adjOR] for 1000 leukocytes increase 1.20, 95% confidence interval [CI] 1.05-1.38), ANC (adjOR for 1000 neutrophils increase 1.34, 95% CI 1.14-1.57), ALC (adjOR for 1000 lymphocytes increase 0.34, 95% CI 0.20-0.59) and NLR (adjOR for 1-point increase 1.49, 95% CI 1.24-1.79) were independently associated with 30-day poor outcome. Predictive accuracy of the Modified ICH score was enhanced by adding the NLR. CONCLUSIONS: The NLR was associated with 30-day mortality and morbidity after ICH, and improved the accuracy of outcome prediction when added to the Modified ICH score. PMID- 29571882 TI - Coming into Focus: Mechanisms of Microtubule Minus-End Organization. AB - Microtubule organization has a crucial role in regulating cell architecture. The geometry of microtubule arrays strongly depends on the distribution of sites responsible for microtubule nucleation and minus-end attachment. In cycling animal cells, the centrosome often represents a dominant microtubule-organizing center (MTOC). However, even in cells with a radial microtubule system, many microtubules are not anchored at the centrosome, but are instead linked to the Golgi apparatus or other structures. Non-centrosomal microtubules predominate in many types of differentiated cell and in mitotic spindles. In this review, we discuss recent advances in understanding how the organization of centrosomal and non-centrosomal microtubule networks is controlled by proteins involved in microtubule nucleation and specific factors that recognize free microtubule minus ends and regulate their localization and dynamics.

The objective of this study is to evaluate quality of life in patients treated for differentiated thyroid carcinoma and look for associated factors. An observational cross-sectional study with comparison group was conducted in the Endocrinology Department of the Ibn Rochd University Hospital between October 2013 and February 2015. The patient group included 124 adult patients followed for differentiated thyroid carcinoma; the control group comprised 124 healthy subjects of the same age. Quality of life was evaluated by 3 questionnaires validated in Arabic: SF36, Hamilton anxiety and Hamilton depression. Patients' quality of life was significantly impaired compared to controls on the two Hamilton and all SF36 scores. Factors influencing quality of life were TNM stage, radioiodine therapy and dose, and the presence of metastases. The psychological management of patients with thyroid cancer is an essential point always to be considered, especially in the presence of risk factors for impaired quality of life. PMID- 29571889 TI - Nationwide questionnaire-based survey of oral immunotherapy in Japan. AB - BACKGROUND: Clinical trials on oral immunotherapy (OIT) have been increasing for nearly a decade; however, several national guidelines do not recommend OIT as a standardized procedure. The aim of this study was to obtain insights into the current use and practice of OIT in Japan. METHODS: A first questionnaire was mailed to 524 training and teaching facilities of the Japan Pediatric Society. The first survey requested information on the implementation of OIT, whereas the second survey aimed to gather more detailed information on OIT, such as its safety. RESULTS: In total, 360 facilities (69%) responded to the survey; among them, 102 (28%) provided OIT to 7973 patients [1544 received OIT while hospitalized (inpatient OIT), whereas 6429 received OIT without hospitalization (outpatient OIT)]. Approval for OIT was obtained from an ethics committee or institutional review board in 89% and 31% of facilities for inpatient and outpatient OIT, respectively. In inpatient OIT, immediate allergic reactions requiring treatment occurred in 68% of patients while hospitalized, and in another 56%, following discharge. In contrast, 11% of patients developed immediate allergic reactions in outpatient OIT. Adrenaline injections at home were required in 2%. Sixteen patients developed adverse reactions other than immediate allergic reactions, among which eosinophilic gastroenteritis was most common. CONCLUSIONS: OIT is widely provided not only as clinical research but also as general practice in Japan. However, because there is a high risk of developing anaphylaxis at home, OIT should be conducted carefully as in a clinical research setting taking safety into consideration. PMID- 29571890 TI - Response of humic acid formation to elevated nitrate during chicken manure composting. AB - Nitrate can stimulate microbes to degrade aromatic compounds, whereas humic acid (HA) as a high molecular weight aromatic compound, its formation may be affected by elevated nitrate during composting. Therefore, this study is conducted to determine the effect of elevated nitrate on HA formation. Five tests were executed by adding different nitrate concentrations to chicken manure composting. Results demonstrate that the concentration of HA in treatment group is significantly decreased compared with control group (p < 0.05), especially in the highest nitrate concentration group. RDA indicates that the microbes associated with HA and environmental parameters are influenced by elevated nitrate. Furthermore, structural equation model reveals that elevated nitrate reduces HA formation by mediating microbes directly, or by affecting ammonia and pH as the indirect drivers to regulate microbial community structure. PMID- 29571891 TI - New insights in photosynthetic microbial fuel cell using anoxygenic phototrophic bacteria. AB - Anoxygenic phototrophic bacteria (APB) pay a key role in biogeochemical cycles, and it can convert light energy to chemical energy by photosynthesis process. Photosynthetic microbial fuel cell (photo-MFC) is regarded as a promising energy harvesting technology, which is also applied to environment treatment in recent years. The previous studies show that photo-MFC with APB have higher power putout than other bioelectrochemical systems. However, photo-MFC with APB is not reviewed due to some limited factors in the development process. In this review, photo-MFC with APB is treated according to its electron transfer pathways, the current understanding, APB strains, application, influence of substrates, and economic assessment. Meanwhile, knowledge of photosynthesis components and electron transfer pathways of APB is crucial for developing new energy and easing the serious energy crisis. Moreover, some new insights (the optimization of light source and self-sustaining bioelectricity generation) are proposed for the future explorations. PMID- 29571892 TI - Omega-3 Polyunsaturated Fatty Acids and Cardiovascular Health: A Comprehensive Review. AB - The potential cardiovascular (CV) disease (CVD) benefits of Omega-3 Polyunsaturated Fatty Acids (OM3) have been intensely studied and debated for decades. Initial trials were performed in patients with low use of maximal medical therapy for CVD, and reported significant mortality benefits with the use of 1 g/day OM3 intervention following myocardial infarction (MI). More recent studies, including cohorts of patients receiving modern guideline directed medical therapy for CVD, have often not shown similar benefits with OM3 use. We conducted a literature review using PubMed, professional society guidelines, specific journal databases including New England Journal of Medicine and Journal of the American College of Cardiology from January 1, 2007 to December 31, 2017. References from selected articles were also reviewed, as well as key articles outside of the selected time-frame for their important findings or historical perspectives. Currently, there are no Class I recommendations from the American Heart Association (AHA) for the use of OM3, however, considering the safety of this therapy and beneficial findings of some modern studies (including patients with current maximal medical therapy for CVD), the AHA has recently expanded their list of Class II recommendations, in which treatment with OM3 for CVD benefit is reasonable. This review discusses the current state of the evidence, summarizes current professional recommendations, and provides recommendations for future research. PMID- 29571893 TI - Air pollution is associated with the development of atherosclerosis via the cooperation of CD36 and NLRP3 inflammasome in ApoE-/- mice. AB - Previous studies have indicated that the main air pollutant fine particulate matter (<=2.5 MUm; PM2.5) exposure is associated with the development of atherosclerosis. Although the mechanism is not fully illustrated, the inflammatory responses play an important role. The present study aimed to explore whether PM2.5-exacerbated atherosclerosis was mediated by the cooperation of cluster of differentiation 36 (CD36) and nucleotide-binding oligomerization domain-like receptor protein (NLRP3) inflammasome in apolipoprotein E-/- (ApoE-/ ) mice. Thirty-two ApoE-/- mice were randomly divided into two groups. One group was fed with high fat chow (HFC) for 10 weeks to establish atherosclerotic model, and the other was fed with normal chow (NC). From week 11, the mice were exposed to concentrated PM2.5 (PM) or filtered air (FA) using Shanghai Meteorological and Environmental Animal Exposure System for 16 weeks. In both NC and HFC groups, PM2.5 exposure induced the formation of atherosclerosis plaque. Similarly, PM mice appeared higher lipid content in the aortic root than that in the FA mice. Compared with the FA mice, PM mice appeared a decrease in high density lipoprotein-cholesterol (HDL-C) and apolipoprotein A1 along with an increase in apolipoprotein B, low density lipoprotein-cholesterol (LDL-C) and oxidized low density lipoprotein (ox-LDL). Moreover, PM2.5 exposure induced increase of CD36 in serum and aorta. In both NC and HFC groups, NLRP3 inflammasome activation related indicators were activated or increased in the aorta of the PM mice when compared with the FA mice. The cooperation of CD36 and NLRP3 inflammasome activation may be the potential mechanisms linkixposed to concentrated PM2.5 (PM) or filtered air (FA) using Shanghai Meteorological and Environmental Animal Exposure System for 16 weeks. In both NC and HFC groups, PM2.5 exposure induced the formation of atherosclerosis plaque. Similarly, PM mice appeared higher lipid content in the aortic root than that in the FA mice. Compared with the FA mice, PM mice appeared a decrease in high density lipoprotein-cholesterol (HDL-C) and apolipoprotein A1 along with an increase in apolipoprotein B, low density lipoprotein-cholesterol (LDL-C) and oxidized low-density lipoprotein (ox-LDL). Moreover, PM2.5 exposure induced increase of CD36 in serum and aorta. In both NC and HFC groups, NLRP3 inflammasome activation-related indicators were activated or increased in the aorta of the PM mice when compared with the FA mice. The cooperation of CD36 and NLRP3 inflammasome activation may be the potential mechanisms linking air pollution and HFC-induced atherosclerosis even in the mice with NC intake.

AB - Cadmium (Cd) is a persistent and widespread environmental pollutant of continuing worldwide concern. Previous studies have suggested that Cd exposure increases the risk of cardiovascular diseases, such as atherosclerosis and hypertension. However, the underlying mechanisms are poorly understood. In this study, we observed that low dose Cd treatment induced von Willebrand factor (vWF) expression in vascular endothelial cells in mouse lung and kidney tissues. In vitro analysis showed that 1 MUM Cd specifically upregulated vWF mRNA and protein expression in human umbilical vein endothelial cells (HUVECs), indicating that Cd targets vascular endothelial cells even at relatively low concentrations. Further study demonstrated that nuclear factor kappa B (NF-kappaB) and GATA3, two established transcription regulators of the vWF gene, were not altered in the presence of Cd. However, ETS-related gene (ERG) was significantly induced by 1 MUM Cd. When ERG was knocked down by siRNA, Cd induced upregulation of vWF was totally blocked. Chromatin immunoprecipitation (ChIP) assay showed that Cd increases the binding of ERG on the -56 ETS motif on the human vWF promoter. These results indicated that ERG mediated the increased expression of vWF by Cd. Since vWF is a key regulator for vascular homeostasis, our findings may provide a novel mechanism for understanding low dose Cd induced development of vascular diseases.

AB - Developmental lead (Pb) exposure results in persistent cognitive/behavioral impairments as well as an elevated risk for developing a variety of diseases in later life. Environmental exposures during development can result in a variety of epigenetic changes, including alterations in DNA methylation, that can influence gene expression patterns and affect the function and development of the nervous system. The present promoter-based methylation microarray profiling study explored the extent to which developmental Pb exposure may modify the methylome of a brain region, hippocampus, known to be sensitive to the effects of Pb exposure. Male and female Long Evans rats were exposed to 0 ppm, 150 ppm, 375 ppm, or 750 ppm Pb through perinatal exposures (gestation through lactation), early postnatal exposures (birth through weaning), or long-term postnatal exposures (birth through postnatal day 55). Results showed a significant contribution of sex to the hippocampal methylome and effects of Pb exposure level, with non-linear dose response effects on methylation. Surprisingly, the developmental period of exposure contributed only a small amount of variance to the overall data and gene ontology (GO) analysis revealed the largest number of overrepresented GO terms in the groups with the lowest level of exposure. The highest number of significant differentially methylated regions was found in females exposed to Pb at the lowest exposure level. Our data reinforce the significant effect that low level Pb exposure may have on gene-specific DNA methylation patterns in brain and that this occurs in a sex-dependent manner.

AB - In utero exposure to certain phthalate esters results in testicular toxicity, characterized at the tissue level by induction of multinucleated germ cells (MNGs) in rat, mouse, and human fetal testis. Phthalate exposures also result in a decrease in testicular testosterone in rats. The anti-androgenic effects of phthalates have been more thoroughly quantified than testicular pathology due to the significant time requirement associated with manual counting of MNGs on histological sections. An automated counting method was developed in ImageJ to quantify MNGs in digital images of hematoxylin-stained rat fetal testis tissue sections. Timed pregnant Sprague Dawley rats were exposed by daily oral gavage from gestation day 17 to 21 with one of eight phthalate test compounds or corn oil vehicle. Both the manual counting method and the automated image analysis method identified di-n-butyl phthalate, butyl benzyl phthalate, dipentyl phthalate, and di-(2-ethylhexyl) phthalate as positive for induction of MNGs. Dimethyl phthalate, diethyl phthalate, the brominated phthalate di-(2-ethylhexyl) tetrabromophthalate, and dioctyl terephthalate were negative. The correlation between automated and manual scoring metrics was high (r = 0.923). Results of MNG analysis were consistent with these compounds' anti-androgenic activities, which were confirmed in an ex vivo testosterone production assay. In conclusion, we have developed a reliable image analysis method that can be used to facilitate dose-response studies for the reproducible induction of MNGs by in utero phthalate exposure.

Despite its recognised debilitating neurological deficits, a devastating clinical complication of surviving stroke patients that needs more attention is infection. Up to half of the patients develop infections after stroke, and a high proportion of them will die as a direct consequence. Major clinical trials that examined preventive antibiotic therapy in stroke patients have demonstrated this method of prevention is not effective as it does not reduce incidence of post-stroke pneumonia or improve patient outcome. Additionally, retrospective studies evaluating the use of beta-blockers for the modulation of the sympathetic nervous system to prevent post-stroke infections have given mixed results. Therefore, there is an urgent need for more effective therapeutic options that target the underlying mechanisms of post-stroke infections. The understanding that infections are largely attributable to the "stroke-induced systemic immunosuppression" phenomenon has begun to emerge, and thus, exploring the pathways that trigger post-stroke immunosuppression is expected to reveal potential new therapeutics. As such, we will outline the impacts that stroke has on several biological systems in this review, and discuss how these contribute to host susceptibility to infection after stroke. Furthermore, the emerging role of the gut and its microbiota has recently come to surface and intensifies the complex pathways to post-stroke infection. Finally, we identify potential avenues to combat infection that target the pathways of stroke-induced systemic immunosuppression to ultimately improve stroke patient outcome.

PMID- 29571900 TI - Invitation letter with a standardized form is a reliable tool to exclude increased risk patients from organized fecal immunological testing-based colorectal cancer screening program. AB - In Europe, screening guidelines for colorectal cancer (CRC) recommend colonoscopy for high-risk patients and fecal immunological testing (FIT) for the standard risk group. Currently, there is not any validated screening tool to exclude high risk patients. The aim of the study is to evaluate the validity of exclusion and evaluate the follow-up of patients identified as increased risk for CRC. In this retrospective study using a prospective database, patients at increased risk were identified using the standardized form and then excluded from the FIT screening invitation. A specific questionnaire was sent to all patients at increased risk in order to confirm the reason for the exclusion and evaluate their follow-up. Among 220 695 eligible individuals, 16 693 (7.5%) were excluded after being characterized at increased risk using the standardized form. The questionnaire was sent to these 16.693 excluded patients and completed by 5076 (30.7%) patients. Validity of exclusion was confirmed in 92% of cases. Endoscopic follow up was in agreement with guideline in 89% of persons at increased risk (inflammatory bowel disease 93%, personal history of CCR 92%, of colonic polyps 82%, family history of CRC 77%). This study suggests that the standardized form is a reliable tool to correctly exclude from the screening program 92% of patients at increased risk for CRC. PMID- 29571901 TI - Disease genes prediction by HMM based PU-learning using gene expression profiles. AB - Predicting disease candidate genes from human genome is a crucial part of nowadays biomedical research. According to observations, diseases with the same phenotype have the similar biological characteristics and genes associated with these same diseases tend to share common functional properties. Therefore, by applying machine learning methods, new disease genes are predicted based on previous ones. In recent studies, some semi-supervised learning methods, called Positive-Unlabeled Learning (PU-Learning) are used for predicting disease candidate genes. In this study, a novel method is introduced to predict disease candidate genes through gene expression profiles by learning hidden Markov models. In order to evaluate the proposed method, it is applied on a mixed part of 398 disease genes from three disease types and 12001 unlabeled genes. Compared to the other methods in literature, the experimental results indicate a significant improvement in favor of the proposed method. PMID- 29571898 TI - Differential immune responses and microbiota profiles in children with autism spectrum disorders and co-morbid gastrointestinal symptoms. AB - OBJECTIVES: Many studies have reported the increased presence of gastrointestinal (GI) symptoms in children with autism spectrum disorders (ASD). Altered microbiome profiles, pro-inflammatory responses and impaired intestinal permeability have been observed in children with ASD and co-morbid GI symptoms, yet few studies have compared these findings to ASD children without GI issues or similarly aged typical developing children. The aim of this study was to determine whether there are biological signatures in terms of immune dysfunction and microbiota composition in children with ASD with GI symptoms. METHODS: Children were enrolled in one of four groups: ASD and GI symptoms of irregular bowel habits (ASDGI), children with ASD but without current or previous GI symptoms (ASDNoGI), typically developing children with GI symptoms (TDGI) and typically developing children without current or previous GI symptoms (TDNoGI). Peripheral blood mononuclear cells (PBMC) were isolated from the blood, stimulated and assessed for cytokine production, while stool samples were analyzed for microbial composition. RESULTS: Following Toll-Like receptor (TLR)-4 stimulation, the ASDGI group produced increased levels of mucosa-relevant cytokines including IL-5, IL-15 and IL-17 compared to ASDNoGI. The production of the regulatory cytokine TGFbeta1 was decreased in the ASDGI group compared with both the ASDNoGI and TDNoGI groups. Analysis of the microbiome at the family level revealed differences in microbiome composition between ASD and TD children with GI symptoms; furthermore, a predictive metagenome functional content analysis revealed that pathways were differentially represented between ASD and TD subjects, independently of the presence of GI symptoms. The ASDGI also showed an over-representation of the gene encoding zonulin, a molecule regulating gut permeability, compared to the other groups. CONCLUSIONS: Overall our findings suggest that children with ASD who experience GI symptoms have an imbalance in their immune response, possibly influenced by or influencing metagenomic changes, and may have a propensity to impaired gut barrier function which may contribute to their symptoms and clinical outcome. PMID- 29571902 TI - Ileal conduit vs orthotopic neobladder: Which one offers the best health-related quality of life in patients undergoing radical cystectomy? A systematic review of literature and meta-analysis. AB - INTRODUCTION: Orthotopic neobladder (ONB) and ileal conduit (IC) are the most commonly practiced techniques of urinary diversion (UD) after radical cystectomy (RC) in bladder cancer patients. Data in the literature is still discordant regarding which UD technique offers the best HR-QoL. OBJECTIVE: The objective was to compare HR-QoL in patients undergoing ONB and IC after RC, through a systematic review of the literature and meta-analysis. MATERIAL AND METHODS: We performed a literature search of PubMed, ScienceDirect, CochraneLibrary and ClinicalTrials.Gov in September 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were subdomains' scores of Bladder Cancer Index BCI: urinary function (UF), urinary bother (UB), bowel function (BF), bowel bother (BB), sexual function (SF) and sexual bother (SB). Continuous outcomes were compared using weighted means differences, with 95% confidence intervals. The presence of publication bias was examined by funnel plots. RESULTS: Four studies met the inclusion criteria. The pooled results demonstrated better UF and UB scores in IC patients: differences were -18.17 (95% CI: -27.49, 8.84, P=0.0001) and -3.72 (95% CI: -6.66, -0.79, P=0.01) respectively. There was no significant difference between IC and ONB patients in terms of BF and BB. SF was significantly better in ONB patients: the difference was 12.7 (95% CI, 6.32, 19.08, P<0.0001). However no significant difference was observed regarding SB. CONCLUSION: This meta-analysis of non-randomized studies demonstrated a better HR QoL in urinary outcomes in IC patients compared with ONB patients.

AB - This review aims at holistically analyzing the environmental problems associated with nitrous oxide (N2O) emissions by evaluating the most important sources of N2O and its environmental impacts. Emissions from wastewater treatment processes and the industrial production of nitric and adipic acid represent nowadays the most important anthropogenic point sources of N2O. Therefore, state-of-the-art strategies to mitigate the generation and release to the atmosphere of this greenhouse and O3-depleting gas in the waste treatment and industrial sectors are also reviewed. An updated review of the end-of-the-pipe technologies for N2O abatement, both in the waste treatment and industrial sectors, is herein presented and critically discussed for the first time. Despite the consistent efforts recently conducted in the development of cost-efficient and eco-friendly N2O abatement technologies, physical/chemical technologies still constitute the most popular treatments for the control of industrial N2O emissions at commercial scale. The recent advances achieved on biological N2O abatement based on heterotrophic denitrification have opened new opportunities for the development of eco-friendly alternatives for the treatment of N2O emissions. Finally, the main limitations and challenges faced by these novel N2O abatement biotechnologies are identified in order to pave the way for market implementation. PMID- 29571904 TI - Assessment of dosimetric errors induced by deformable image registration methods in 4D pencil beam scanned proton treatment planning for liver tumours. AB - PURPOSE: Respiratory impacts in pencil beam scanned proton therapy (PBS-PT) are accounted by extensive 4D dose calculations, where deformable image registration (DIR) is necessary for estimating deformation vector fields (DVFs). We aim here to evaluate the dosimetric errors induced by different DIR algorithms in their resulting 4D dose calculations by using ground truth(GT)-DVFs from 4DMRI. MATERIALS AND METHODS: Six DIR methods: ANACONDA, Morfeus, B-splines, Demons, CT Deformable, and Total Variation, were respectively applied to nine 4DCT-MRI liver data sets. The derived DVFs were then used as input for 4D dose calculation. The DIR induced dosimetric error was assessed by individually comparing the resultant 4D dose distributions to those obtained with GT-DVFs. Both single-/three-field plans and single/rescanned strategies were investigated. RESULTS: Differences in 4D dose distributions among different DIR algorithms, and compared to the results using GT-DVFs, were pronounced. Up to 40 % of clinically relevant dose calculation points showed dose differences of 10 % or more between the GT. Differences in V95(CTV) reached up to 11.34 +/- 12.57 %. The dosimetric errors became in general less substantial when applying multiple-field plans or using rescanning. CONCLUSION: Intrinsic geometric errors by DIR can influence the clinical evaluation of liver 4D PBS-PT plans. We recommend the use of an error bar for correctly interpreting individual 4D dose distributions. PMID- 29571905 TI - An Ancestral Gibberellin in a Moss Physcomitrella patens. PMID- 29571906 TI - [Emergency eye care in French university hospitals]. AB - INTRODUCTION: The patient's request for urgent care in ophthalmology (PRUCO) at health care centers is constantly growing. In France, university hospitals are managing 75% of these cases. We sought to quantify PRUCO referred to French university hospital emergency units as well as to approach the structure and the territorial distribution of emergency eye care provided by French university hospitals. METHODS: We conducted a quick cross-sectional survey sent to the 32 metropolitan and overseas French university hospitals. It inquired for each hospital whether emergency eye care units were available, whether ophthalmologists were on duty or on call overnight and how many PRUCO were managed in 2016. RESULTS: The 32 university hospitals completed the survey. A total of 398650 PRUCO were managed in French university hospitals in 2016. The emergency unit was exclusively dedicated to eye care for 70% of the hospitals, with 47% (15/32) of them employing an ophthalmologist on duty overnight. Every hospital but one had at least one ophthalmologist on call. The city of Paris set aside, university hospitals took care of an annual mean of 9000 PRUCO (min=500; max=32,250). CONCLUSION: The 32 French university hospitals are actively responding to patient's requests for urgent care in ophthalmology with very heterogeneous patient volumes and organizational systems. Half of them employ ophthalmologists on duty. PMID- 29571907 TI - The Effects of Endodontic Access Cavity Preparation Design on the Fracture Strength of Endodontically Treated Teeth: Traditional Versus Conservative Preparation. AB - INTRODUCTION: The aim of this study was to compare the fracture strengths of mandibular molar teeth prepared using traditional endodontic cavity (TEC) and conservative endodontic cavity (CEC) methods and restored using SDR (Dentsply Caulk, Milford, DE) and EverX Posterior (GC Dental, Tokyo, Japan) base composite materials. METHODS: A hundred mandibular first molar teeth were randomly divided into 5 groups. In group 1 (the control group), samples were kept intact. In group 2, TECs were prepared, and the samples were restored with EverX Posterior and composite resin. In group 3, CECs were prepared, and the samples were restored with EverX Posterior and composite resin. In group 4, TECs were prepared, and the samples were restored with SDR and composite resin. In group 5, CECs were prepared, and the samples were restored with SDR and composite resin. This load was applied on the samples at 1-mm/min speed using a 6-mm round-head tip until fracture. The forces resulting in fracture were recorded in newton units. The data were analyzed using Kruskal-Wallis and Pearson correlation tests at a 5% significance level. RESULTS: The fracture strengths of the samples in the control group were significantly higher than the experimental groups (P < .05). There was no statistically significant difference in the endodontic access cavities prepared used the TEC and CEC methods and restored using the same composite base material (P > .05). CONCLUSIONS: CEC preparation did not increase the fracture strength of teeth with class II cavities compared with TEC preparation. The fracture strength of teeth restored with the SDR bulk-fill composite was higher than that of teeth restored with EverX Posterior.

AB - INTRODUCTION: A greater irrigant volume improves the effectiveness of root canal irrigation. The purpose of this study was to compare 2 negative pressure systems regarding the volume of irrigant collected from the apical area in moderately curved canals at 3 different flow rates of delivery in vitro. METHODS: The mesiobuccal canals of 30 molars with a curvature between 20 degrees and 40 degrees were prepared to size #40.04 taper. A closed system was created. The canals were irrigated at 3, 6, and 12 mL/min for 30 seconds using EndoVac (SybronEndo, Orange, CA) and the INP needle (Mixnus Fine Engineering Co Ltd, Nagano, Japan) (both independent variables). A recovery trap was used to collect the irrigant aspirated by the negative pressure needles. Irrigant volume (dependent variable) was measured in milliliters. Data were analyzed using mixed analysis of variance. RESULTS: There was a statistically significant interaction between the negative pressure system and the irrigant volume collected (P < .0005). The mean irrigant volume collected by the different negative pressure systems was greater for INP at 3 (P < .001), 6 (P < .001), and 12 mL/min (P < .001) flow rate. Both negative pressure needles showed statistically significant differences (P < .001) between mean irrigant volume collected at different flow rates. CONCLUSIONS: A greater volume was collected by increasing the flow rate of irrigant delivery for both EndoVac and INP. The INP needle could collect a greater volume of irrigant from the apical third compared with EndoVac at all 3 different flow rates. PMID- 29571909 TI - Inhibition of SOX9 Promotes Inflammatory and Immune Responses of Dental Pulp. AB - INTRODUCTION: The process of pulpitis is characterized by extracellular matrix imbalance and inflammatory cell infiltration. As an essential transcription factor, sex-determining region Y-box 9 (SOX9) is significantly inhibited by tumor necrosis factor alpha in inflammatory joint diseases. The aim of this study was to explore the role of SOX9 in extracellular matrix balance, cytokine expression, and the immune response in dental pulp. METHODS: The expression of SOX9 in normal and inflamed pulp tissue/human dental pulp cells (HDPCs) was detected by immunohistochemistry, Western blot, and quantitative polymerase chain reaction (qPCR). SOX9 small interfering RNA was used to knock down SOX9 expression of dental cells in vitro; extracellular matrix imbalance was analyzed by qPCR, Western blot, and gelatin/collagen zymography, and the secretion of cytokines was scanned by antibody arrays. The immune response of THP-1 was investigated by cell migration assay, cell attachment assay, phagocytosis assay, and enzyme-linked immunosorbent assay. The interaction of SOX9 with target genes was explored by chromatin immunoprecipitation (ChIP). RESULTS: SOX9 was strongly expressed in normal dental pulp tissue and HDPCs and reduced in inflamed pulp. SOX9 knockdown could inhibit the production of type I collagen, stimulate the enzymatic activities of MMP2 and MMP13, and regulate the production of interleukin (IL) 8 of HDPCs. SOX9 knockdown also effectively suppressed the differentiation and functional activities of THP-1. ChIP showed that the binding of the SOX9 protein with matrix metalloproteinase (MMP)-1, MMP-13, and IL-8 gene promoters was reduced after being treated with recombinant human tumor necrosis factor alpha. CONCLUSIONS: SOX9 was inhibited in inflamed dental pulp and may participate in the regulation of extracellular matrix balance, the inflammatory process, and the immune response. PMID- 29571910 TI - Guided Endodontic Access in Maxillary Molars Using Cone-beam Computed Tomography and Computer-aided Design/Computer-aided Manufacturing System: A Case Report. AB - The aim of this study was to describe a guided endodontic technique that facilitates access to root canals of molars presenting with pulp calcifications. A 61-year-old woman presented to our service with pain in the upper left molar region. The second and third left molars showed signs of apical periodontitis confirmed by the cone-beam computed tomographic (CBCT) scans brought to us by the patient at the initial appointment. Conventional endodontic treatment was discontinued given the difficulty in locating the root canals. Intraoral scanning and the CBCT scans were used to plan the access to the calcified canals by means of implant planning software. Guides were fabricated through rapid prototyping and allowed for the correct orientation of a cylindrical drill used to provide access through the calcifications. Second to that, the root canals were prepared with reciprocating endodontic instruments and rested for 2 weeks with intracanal medication. Subsequently, canals were packed with gutta-percha cones using the hydraulic compression technique. Permanent restorations of the access cavities were performed. By comparing the tomographic images, the authors observed a drastic reduction of the periapical lesions as well as the absence of pain symptoms after 3 months. This condition was maintained at the 1-year follow-up. The guided endodontic technique in maxillary molars was shown to be a fast, safe, and predictable therapy and can be regarded as an excellent option for the location of calcified root canals, avoiding failures in complex cases. PMID- 29571911 TI - A Novel Method for Characterizing Beam Hardening Artifacts in Cone-beam Computed Tomographic Images. AB - INTRODUCTION: The beam hardening (BH) artifact produced by root filling materials in cone-beam computed tomographic (CBCT) images is influenced by their radiologic K absorption edge values. The purpose of this study was to describe a novel technique to characterize BH artifacts in CBCT images produced by 3 root canal filling materials and to evaluate the effects of a zirconium (Zr)-based root filling material with a lower K edge (17.99 keV) on the production of BH artifacts. METHODS: The palatal root canals of 3 phantom model teeth were prepared and root filled with gutta-percha (GP), a Zr root filling material, and calcium hydroxide paste. Each phantom tooth was individually imaged using the CS 9000 CBCT unit (Carestream, Atlanta, GA). The "light" and "dark" components of the BH artifacts were quantified separately using ImageJ software (National Institutes of Health, Bethesda, MD) in 3 regions of the root. Mixed-design analysis of variance was used to evaluate differences in the artifact area for the light and dark elements of the BH artifacts. RESULTS: A statistically significant difference in the area of the dark portion of the BH artifact was found between all fill materials and in all regions of the phantom tooth root (P < .05). GP generated a significantly greater dark but not light artifact area compared with Zr (P < .05). Moreover, statistically significant differences between the areas of both the light and dark artifacts were observed within all regions of the tooth root, with the greatest artifact being generated in the coronal third of the root (P < .001). CONCLUSIONS: Root canal filling materials with lower K edge material properties reduce BH artifacts along the entire length of the root canal and reduce the contribution of the dark artifact. PMID- 29571912 TI - Mechanical Properties of Glide Path Preparation Instruments with Different Pitch Lengths. AB - INTRODUCTION: This study compared the effects of pitch length on the torsional resistance and cyclic fatigue resistance of glide path preparation instruments. METHODS: G-File (G1 and G2; Micro-Mega, Besancon, France) and new generation G File (NG1 and NG2, Micro-Mega) instruments were compared to evaluate the effects of the shorter pitch of the latter (25% shorter than G-File). G1 and NG1 have a #12 tip size, whereas G2 and NG2 have a #17 tip size. All the files have the same taper of 3%. For comparing the torsional resistances (n = 15), the file was fixed at 4 mm from the tip, and the clockwise rotation at a constant rotational speed of 2 rpm was adjusted until the file fractured. The maximum torsional load and distortion angle at fracture were recorded. For comparing the cyclic fatigue resistances (n = 15), the files were freely rotated in a simulated canal (radius, 3 mm; curvature, 90 degrees ) at a speed of 300 rpm in a dynamic mode. When the file fractured, the time elapsed was recorded using a chronometer. The number of cycles to failure was calculated by multiplying the total time to failure by the rotation rate. Fractured fragments were examined under the scanning electron microscope. RESULTS: The NG2 instruments had significantly higher fatigue resistance and torsional strength than the G2 instruments (P < .05) and showed approximately the same fatigue resistance as the G1. Scanning electron microscopic examinations revealed the typical appearances of 2 failure modes. CONCLUSIONS: A shorter pitch design increased cyclic fatigue resistance and torsional strength of the glide path instruments. PMID- 29571913 TI - Is the Use of Dexamethasone Effective in Controlling Pain Associated with Symptomatic Irreversible Pulpitis? A Systematic Review. AB - INTRODUCTION: Endodontic pain is a symptom of pulpal and/or periapical inflammation. One strategy for pain reduction is using medications, such as dexamethasone. A definitive protocol for preventing and controlling pain caused by irreversible pulpitis during endodontic treatment has not yet been established. This is a systematic review to answer the following question: is the use of dexamethasone effective in controlling pain associated with symptomatic irreversible pulpitis? METHODS: This study was registered in the PROSPERO database (CRD42017058704), and Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement recommendations were followed. MEDLINE, Scopus, ScienceDirect, Web of Science, Latin American Caribbean Health Sciences Literature, Cochrane Library, and Google Scholar databases were used in our research. No restrictions were applied to dates or language of publication. All records identified electronically were organized and evaluated by 2 independent authors, and, in case of doubt, a third author made the decision. The Cochrane Collaboration tool was used. The data were analyzed with RevMan 5 software (The Cochrane Collaboration, Copenhagen, Denmark), and data from eligible studies were dichotomous (with and without pain). RESULTS: A total of 4825 studies were identified. After screening, 523 studies were selected, and, after careful evaluation, only 5 articles remained. All meta-analyses revealed a global effect (P < .05, P < .05, and P < .05), which means that 4 mg dexamethasone helps relieve pain, sometimes for up to 8, 12, and 24 hours. CONCLUSIONS: The pain felt by patients diagnosed with symptomatic irreversible pulpitis may be alleviated by administering 4 mg dexamethasone either by mouth or through intraligamentary and mainly supraperiosteal injections into the root canal for up to 24 hours. PMID- 29571914 TI - Diagnostic Accuracy of 5 Dental Pulp Tests: A Systematic Review and Meta analysis. AB - INTRODUCTION: The aim of this systematic review was to investigate and compare the diagnostic accuracy including sensitivity, specificity, adjusted accuracy, adjusted positive predictive value (PPV), and adjusted negative predictive value (NPV) of cold pulp testing (CPT), heat pulp testing (HPT), electric pulp testing (EPT), laser Doppler flowmetry (LDF), and pulse oximetry (PO). METHODS: Three electronic databases were searched from January 1964 to December 2016. True positive, false-positive, true-negative, and false-negative values were extracted from data in each study. Sensitivity, specificity, adjusted accuracy, adjusted PPV, and adjusted NPV were calculated from those values, if not presented. A random effects model was used to calculate pooled estimates of sensitivity, specificity, adjusted accuracy, adjusted PPV, and adjusted NPV. RESULTS: A total of 125 articles were identified, and 28 studies were included for the final review. The pooled estimates of sensitivity for CPT, EPT, HPT, LDF, and PO were 0.87, 0.72, 0.78, 0.98, and 0.97, respectively. Those of specificity were 0.84, 0.93, 0.67, 0.95, and 0.95, respectively. Those of adjusted accuracy were 0.84, 0.82, 0.72, 0.97, and 0.97, respectively. For adjusted PPV, they were 0.81, 0.89, 0.62, 0.94, and 0.94, respectively, and for adjusted NPV, they were 0.87, 0.80, 0.79, 1.00, and 0.99, respectively. CONCLUSIONS: LDF and PO were the most accurate diagnostic methods, and HPT was the least accurate diagnostic method. EPT showed high accuracy when testing vital teeth (specificity = 0.93) but low accuracy when assessing nonvital teeth (sensitivity = 0.72). CPT had moderate accuracy when evaluating vital (specificity = 0.84) and nonvital (sensitivity = 0.87) teeth.

AB - INTRODUCTION: The aim of this study was to compare the effect of resin-based and bioceramic root canal sealers on the occurrence and intensity of postoperative pain in patients with asymptomatic apical periodontitis (AAP). METHODS: Patients presenting with AAP in previously endodontically treated teeth were included in this split-mouth blinded randomized controlled trial. For each patient, 2 single rooted teeth were retreated and obturated using the warm vertical condensation technique and different obturation materials (ie, a gutta-percha point with resin based sealer and a bioceramic-coated gutta-percha point with bioceramic sealer). Treatment of 1 root canal was performed in a single visit. Postoperative pain was recorded by a visual analog scale (VAS) at 24 hours, 48 hours, 72 hours, and 7 days after obturation. RESULTS: Of the 61 included patients, 57 individuals presenting 114 teeth completed the study. There was no statistically significant difference between the tested root canal sealers regarding postoperative pain at any time points assessed (P > .05). In total, 20 (35%) patients perceived pain. Only 1 patient reported severe pain. VAS scores of 80 and 70 were reported in the AH Plus (Dentsply Maillefer, Ballaigues, Switzerland) and Total Fill (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland) groups, respectively. Pain intensity decreased about 2-fold in both groups at 48 hours after treatment. There were no reports of pain since 72 hours after obturation. The odds ratio for pain occurrence in the lower premolars was 7.2 (95% confidence interval, 1.708-30.352) compared with the upper front teeth. CONCLUSIONS: AH Plus and Total Fill perform similarly in terms of the occurrence and intensity of postoperative pain in teeth with AAP with no material extrusion beyond the apex.

AB - 22q11.2 deletion syndrome (22q11.2DS) carries increased risk for both physical and psychiatric symptoms, including a high risk for schizophrenia. Understanding the genetic elements within the deletion region therefore has the potential to unlock the mysteries of both diseases. While most of the protein-coding genes in this region have been characterized, novel elements, such as non-coding RNAs and small Open Reading Frames (sORFs) remain unstudied. We have identified a novel, highly-conserved mouse sORF in a region of the mouse genome that is orthologous to a portion of the 22q11.2 deletion. This region was previously associated with age-dependent synaptic plasticity abnormalities. We refer to it as the Plasticity Associated Neural Transcript Short, or Pants. In developing and aging mouse brain, Pants expression is strongest in hippocampus, especially in areas CA3 and CA2, throughout the dorsoventral axis. The Pants peptide is expressed throughout the hippocampus, with an age-dependent increase in stratum lucidum at 16 weeks of age. This expression pattern suggests a potential role for Pants in many hippocampal behaviors, as well as a potential role in the age-dependent neurologic deficits displayed by 22q11.2DS model mice and patients.

PMID- 29571921 TI - Genetic diversity and symbiotic effectiveness of Phaseolus vulgaris-nodulating rhizobia in Kenya. AB - Phaseolus vulgaris (common bean) was introduced to Kenya several centuries ago but the rhizobia that nodulate it in the country remain poorly characterised. To address this gap in knowledge, 178 isolates recovered from the root nodules of P. vulgaris cultivated in Kenya were genotyped stepwise by the analysis of genomic DNA fingerprints, PCR-RFLP and 16S rRNA, atpD, recA and nodC gene sequences. Results indicated that P. vulgaris in Kenya is nodulated by at least six Rhizobium genospecies, with most of the isolates belonging to Rhizobium phaseoli and a possibly novel Rhizobium species. Infrequently, isolates belonged to Rhizobium paranaense, Rhizobium leucaenae, Rhizobium sophoriradicis and Rhizobium aegyptiacum. Despite considerable core-gene heterogeneity among the isolates, only four nodC gene alleles were observed indicating conservation within this gene. Testing of the capacity of the isolates to fix nitrogen (N2) in symbiosis with P. vulgaris revealed wide variations in effectiveness, with ten isolates comparable to Rhizobium tropici CIAT 899, a commercial inoculant strain for P. vulgaris. In addition to unveiling effective native rhizobial strains with potential as inoculants in Kenya, this study demonstrated that Kenyan soils harbour diverse P. vulgaris-nodulating rhizobia, some of which formed phylogenetic clusters distinct from known lineages. The native rhizobia differed by site, suggesting that field inoculation of P. vulgaris may need to be locally optimised. PMID- 29571923 TI - Prevalence and long-term monitoring of humoral immunity against adeno-associated virus in Duchenne Muscular Dystrophy patients. AB - Adeno-associated virus (AAV) vectors are promising candidates for gene therapy and have been explored as gene delivery vehicles in the treatment of Duchenne Muscular Dystrophy (DMD). Recent studies showed compelling evidence of therapeutic efficacy in large animal models following the intravenous delivery of AAV vectors expressing truncated forms of dystrophin. However, to translate these results to humans, careful assessment of the prevalence of anti-AAV neutralizing antibodies (NAbs) is needed, as presence of preexisting NABs to AAV in serum have been associated with a drastic diminution of vector transduction. Here we measured binding and neutralizing antibodies against AAV serotype 1, 2, and 8 in serum from children and young adults with DMD (n = 130). Results were compared with to age-matched healthy donors (HD, n = 113). Overall, approximately 54% of all subjects included in the study presented IgG to AAV2, 49% to AAV1, and 41% to AAV8. A mean of around 80% of IgG positive sera showed neutralizing activity with no statistical difference between DMD and HD. NAb titers for AAV2 were higher than AAV1, and AAV8 in both populations studied. Older DMD patients (13-24 years old) presented significantly lower anti-AAV8 IgG4 subclass. Anti-AAV antibodies were found to be decreased in DMD patients subjected to a 6-month course of corticosteroids and in subjects receiving a variety of immunosuppressive drugs including B cell targeting drugs. Longitudinal follow up of humoral responses to AAV over up to 6 years showed no change in antibody titers, suggesting that in this patient population, seroconversion is a rare event in humans. PMID- 29571924 TI - High red and processed meat consumption is associated with non-alcoholic fatty liver disease and insulin resistance. AB - BACKGROUND & AIMS: High red and processed meat consumption is related to type 2 diabetes. In addition, cooking meat at high temperatures for a long duration forms heterocyclic amines (HCAs), which are related to oxidative stress. However, the association between meat consumption and non-alcoholic fatty liver disease (NAFLD) is yet to be thoroughly tested. Therefore, we aimed to test the association of meat type and cooking method with NAFLD and insulin resistance (IR). METHODS: This was a cross-sectional study in individuals who were 40-70 years old and underwent screening colonoscopy between 2013 and 2015 in a single center in Israel. NAFLD and IR were evaluated by ultrasonography and homeostasis model assessment. Meat type and cooking method were measured by a food frequency questionnaire (FFQ) and a detailed meat questionnaire. Unhealthy cooking methods were considered as frying and grilling to a level of well done and very well done. Dietary HCA intake was calculated. RESULTS: A total of 789 individuals had a valid FFQ and 357 had a valid meat questionnaire. High consumption of total meat (portions/day above the median) (odds ratio [OR] 1.49; 95% CI 1.05-2.13; p = 0.028; OR 1.63; 1.12-2.37; p = 0.011), red and/or processed meat (OR1.47; 95% CI 1.04-2.09; p = 0.031; OR1.55; 1.07-2.23; p = 0.020) was independently associated with higher odds of NAFLD and IR, respectively, when adjusted for: body mass index, physical activity, smoking, alcohol, energy, saturated fat and cholesterol intake. High intake of meat cooked using unhealthy methods (OR1.92; 95% CI 1.12 3.30; p = 0.018) and HCAs (OR2.22; 95% CI 1.28-3.86; p = 0.005) were independently associated with higher odds of IR. CONCLUSION: High consumption of red and/or processed meat is associated with both NAFLD and IR. High HCA intake is associated with IR. If confirmed in prospective studies, limiting the consumption of unhealthy meat types and improving preparation methods may be considered as part of NAFLD lifestyle treatment. LAY SUMMARY: High red and processed meat consumption is related to several diseases. In addition, cooking meat at high temperatures for a long duration forms heterocyclic amines, which have harmful health effects. Non-alcoholic fatty liver disease is a significant public health burden and its formation is strongly related to insulin resistance. In this study, both were found to be more frequent in people who consume relatively high quantities of red and processed meat. In addition, a high intake of heterocyclic amines was associated with insulin resistance. PMID- 29571925 TI - Mortality Risk and Hospital Admission after a Brief Resolved Unexplained Event.

PMID- 29571927 TI - Implicit Physician Biases in Periviability Counseling. AB - OBJECTIVE: To assess whether neonatologists show implicit racial and/or socioeconomic biases and whether these are predictive of recommendations at extreme periviability. STUDY DESIGN: A nationwide survey using a clinical vignette of a woman in labor at 232/7 weeks of gestation asked physicians how likely they were to recommend intensive vs comfort care. Participants were randomized to 1 of 4 versions of the vignette in which racial and socioeconomic stimuli were varied, followed by 2 implicit association tests (IATs). RESULTS: IATs revealed implicit preferences favoring white (mean IAT score = 0.48, P < .001) and greater socioeconomic status (mean IAT score = 0.73, P < .001). Multivariable linear regression analysis showed that physicians with implicit bias toward greater socioeconomic status were more likely than those without bias to recommend comfort care when presented with a patient of high socioeconomic status (P = .037). No significant effect was seen for implicit racial bias. CONCLUSIONS: Building on previous demonstrations of unconscious racial and socioeconomic biases among physicians and their predictive validity, our results suggest that unconscious socioeconomic bias influences recommendations when counseling at the limits of viability. Physicians who display a negative socioeconomic bias are less likely to recommend resuscitation when counseling women of high socioeconomic status. The influence of implicit socioeconomic bias on recommendations at periviability may influence neonatal healthcare disparities and should be explored in future studies. PMID- 29571928 TI - Hemodynamic Changes During Rewarming Phase of Whole-Body Hypothermia Therapy in Neonates with Hypoxic-Ischemic Encephalopathy. AB - OBJECTIVE: To delineate the systemic and cerebral hemodynamic response to incremental increases in core temperature during the rewarming phase of therapeutic hypothermia in neonatal hypoxic-ischemic encephalopathy (HIE). STUDY DESIGN: Continuous hemodynamic data, including heart rate (HR), mean arterial blood pressure (MBP), cardiac output by electrical velocimetry (COEV), arterial oxygen saturation, and renal (RrSO2) and cerebral (CrSO2) regional tissue oxygen saturation, were collected from 4 hours before the start of rewarming to 1 hour after the completion of rewarming. Serial echocardiography and transcranial Doppler were performed at 3 hours and 1 hour before the start of rewarming (T-3 and T-1; "baseline") and at 2, 4, and 7 hours after the start of rewarming (T+2, T+4, and T+7; "rewarming") to determine Cardiac output by echocardiography (COecho), stroke volume, fractional shortening, and middle cerebral artery (MCA) flow velocity indices. Repeated-measures analysis of variance was used for statistical analysis. RESULTS: Twenty infants with HIE were enrolled (mean gestational age, 38.8 +/- 2 weeks; mean birth weight, 3346 +/- 695 g). During rewarming, HR, COecho, and COEV increased from baseline to T+7, and MBP decreased. Despite an increase in fractional shortening, stroke volume remained unchanged. RrSO2 increased, and renal fractional oxygen extraction (FOE) decreased. MCA peak systolic flow velocity increased. There were no changes in CrSO2 or cerebral FOE. CONCLUSIONS: In neonates with HIE, CO significantly increases throughout rewarming. This is due to an increase in HR rather than stroke volume and is associated with an increase in renal blood flow. The lack of change in cerebral tissue oxygen saturation and extraction, in conjunction with an increase in MCA peak systolic velocity, suggests that cerebral flow metabolism coupling remained intact during rewarming. PMID- 29571929 TI - Pediatric Tonsil Cancer: A National and Institutional Perspective. AB - OBJECTIVE: To evaluate childhood and adolescent tonsil cancer incidence and to identify the clinical characteristics indicative of those patients who would benefit from urgent operative intervention. STUDY DESIGN: The Surveillance, Epidemiology and End Results 18 database, inclusive of national cancer statistics from 1973 to 2013, provided quantitative tonsil cancer incidence data. An institutional retrospective chart review of pediatric patients diagnosed with tonsil malignancy from January 2013 to January 2017 identified supplementary qualitative clinical presentation information. RESULTS: The Surveillance, Epidemiology and End Results 18 database included 138 pediatric patients with tonsil cancer with an age-adjusted incidence rate of 0.021/100 000 patients per year. The majority of cases were unilateral (79.7%), and there was both a male and Caucasian predominance. Non-Hodgkin lymphoma (84.1%) was the most common malignancy, of which Burkitt lymphoma (31.1%), diffuse large B-cell lymphoma (26.8%), and follicular lymphoma (10.1%) were the most common subtypes. Five tonsillar malignancy patients were identified upon institutional chart review. The majority likewise had non-Hodgkin lymphoma and all shared a history of rapid tonsillar enlargement over <=12 weeks. Significant tonsillar asymmetry was present in 4 patients. Four patients additionally exhibited prominent cervical lymphadenopathy. CONCLUSIONS: Pediatric tonsil cancer is rare, with non-Hodgkin lymphoma accounting for the majority of pediatric tonsillar malignancies. A high index of suspicion is appropriate in children who present with relatively rapid tonsil enlargement, tonsillar asymmetry characterized by a difference in tonsillar size of >=2 degrees on the Brodsky scale, or concurrent prominent cervical lymphadenopathy. PMID- 29571931 TI - Effectiveness of Pediatric Asthma Pathways for Hospitalized Children: A Multicenter, National Analysis. AB - OBJECTIVE: To determine if clinical pathways affect care and outcomes for children hospitalized with asthma using a multicenter study. STUDY DESIGN: This was a retrospective, multicenter cohort study using an administrative database, the Pediatric Health Information System. We evaluated the impact of inpatient pediatric asthma pathways on children age 2-17 years admitted for asthma from 2006 to 2015 in 42 children's hospitals. Date of pathway implementation for each hospital was collected via survey. Using generalized estimating equations with an interrupted time series approach (to account for secular trends), we determined the association of pathway implementation with length of stay (LOS), 30-day readmission, chest radiograph utilization, ipratropium administration >24 hours, and administration of bronchodilators, systemic steroids, and antibiotics. All analyses were risk-adjusted for patient and hospital characteristics. RESULTS: Clinical pathway implementation was associated with an 8.8% decrease in LOS (95% CI 6.7%-10.9%), 3.1% decrease in hospital costs (95% CI 1.9%-4.3%), increased odds of bronchodilator administration (OR 1.53[1.21-1.95]) and decreased odds of antibiotic administration (OR 0.93[0.87-0.99]) (n = 189 331). We found no associations between pathway implementation and systemic steroid administration, ipratropium administration for >24 hours, chest radiograph utilization, or 30-day readmission. CONCLUSIONS: Clinical pathways can decrease LOS, costs, and unnecessary antibiotic use without increasing rates of readmissions, leading to higher value care. PMID- 29571932 TI - Optimal Target Range of Closed-Loop Inspired Oxygen Support in Preterm Infants: A Randomized Cross-Over Study. AB - OBJECTIVE: To investigate the effect of different pulse oximetry (SpO2) target range settings during automated fraction of inspired oxygen control (A-FiO2) on time spent within a clinically set SpO2 alarm range in oxygen-dependent infants on noninvasive respiratory support. STUDY DESIGN: Forty-one preterm infants (gestational age [median] 26 weeks, age [median] 21 days) on FiO2 >0.21 receiving noninvasive respiratory support were subjected to A-FiO2 using 3 SpO2 target ranges (86%-94%, 88%-92%, or 89%-91%) in random order for 24 hours each. Before switching to the next target range, SpO2 was manually controlled for 24 hours (washout period). The primary outcome was the time spent within the clinically set alarm limits of 86%-94%. RESULTS: The percent time within the 86%-94% SpO2 alarm range was similar for all 3 A-FiO2 target ranges (74%). Time spent in hyperoxemia was not significantly different between target ranges. However, the time spent in severe hypoxemia (SpO2 <80%) was significantly reduced during the narrowed target ranges of A-FiO2 (88%-92%; 1.9%, 89%-91%; 1.7%) compared with the wide target range (86%-94%; 3.4%, P < .001). There were no differences between the 88%-92% and 89-91% target range. CONCLUSIONS: Narrowing the target range of A FiO2 to the desired median +/-2% is effective in reducing the time spent in hypoxemia, without increasing the risk of hyperoxemia.

AB - OBJECTIVE: To compare healthcare transition planning in adolescents with Down syndrome with adolescents with other special healthcare needs. STUDY DESIGN: Data were drawn from the 2009-2010 National Survey of Children with Special Health Care Needs, a nationally representative sample with 17 114 adolescents aged 12-17 years. Parents were asked whether providers and the study child had discussed shifting to an adult provider, changing healthcare needs, maintaining health insurance coverage, and taking responsibility for self-care. The transition core outcome was a composite measure based on the results of these 4 questions. Multivariable logistic regression determined the association between Down syndrome and the transition core outcome as well as each of the 4 individual component measures. RESULTS: Although 40% of adolescents with other special healthcare needs met the transition core outcome, 11.0% of adolescents with Down syndrome met this outcome. Adolescents with Down syndrome were less likely to be encouraged to take responsibility for their health (32.2% vs 78.4%). After adjustment for demographic, socioeconomic, and health-related factors, adolescents with Down syndrome had 4 times the odds of not meeting the transition core outcome. For the component measures, Down syndrome adolescents had 4 times the odds of not being encouraged to take responsibility for self-care. Medical home access increased the odds of transition preparation. CONCLUSIONS: Adolescents with Down syndrome experience disparities in access to transition services. Provider goals for adolescents with Down syndrome should encourage as much independence as possible in their personal care and social lives. PMID- 29571930 TI - HABIT, a Randomized Feasibility Trial to Increase Hydroxyurea Adherence, Suggests Improved Health-Related Quality of Life in Youths with Sickle Cell Disease. AB - OBJECTIVES: To examine the effect of a community health worker (CHW) intervention, augmented by tailored text messages, on adherence to hydroxyurea therapy in youths with sickle cell disease, as well as on generic and disease specific health-related quality of life (HrQL) and youth-parent self-management responsibility concordance. STUDY DESIGN: We conducted a 2-site randomized controlled feasibility study (Hydroxyurea Adherence for Personal Best in Sickle Cell Treatment [HABIT]) with 2:1 intervention allocation. Youths and parents participated as dyads. Intervention dyads received CHW visits and text message reminders. Data were analyzed using descriptive statistics, the Wilcoxon signed rank test, and growth models adjusting for group assignment, time, and multiple comparisons. Changes in outcomes from 0 to 6 months were compared with their respective minimal clinically important differences. RESULTS: A total of 28 dyads (mean age of youths, 14.3 +/- 2.6 years; 50% Hispanic) participated (18 in the intervention group, 10 in the control group), with 10.7% attrition. Accounting for group assignment, time, and multiple comparisons, at 6 months intervention youths reported improved generic HrQL total score (9.8 points; 95% CI, 0.4-19.2) and Emotions subscale score (15.0 points; 95% CI, 1.6-28.4); improved disease specific subscale scores for Worry I (30.0 points; 95% CI, 8.5-51.5), Emotions (37.0 points, 95% CI, 9.4-64.5), and Communication I (17.8 points; 95% CI, 0.5 35.1); and 3-month dyad self-management responsibility concordance (3.5 points; 95% CI, -0.2 to 7.1). There were no differences in parent proxy-reported HrQL measures at 6 months. CONCLUSIONS: These findings add to research examining effects of behavioral interventions on HrQL outcomes in youths with sickle cell disease. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02029742. PMID- 29571934 TI - Multi-institutional evaluation of end-to-end protocol for IMRT/VMAT treatment chains utilizing conventional linacs. AB - We conducted a multi-institutional assessment of a recently developed end-to-end monthly quality assurance (QA) protocol for external beam radiation therapy treatment chains. This protocol validates the entire treatment chain against a baseline to detect the presence of complex errors not easily found in standard component-based QA methods. Participating physicists from 3 institutions ran the end-to-end protocol on treatment chains that include Imaging and Radiation Oncology Core (IROC)-credentialed linacs. Results were analyzed in the form of American Association of Physicists in Medicine (AAPM) Task Group (TG)-119 so that they may be referenced by future test participants. Optically stimulated luminescent dosimeter (OSLD), EBT3 radiochromic film, and A1SL ion chamber readings were accumulated across 10 test runs. Confidence limits were calculated to determine where 95% of measurements should fall. From calculated confidence limits, 95% of measurements should be within 5% error for OSLDs, 4% error for ionization chambers, and 4% error for (96% relative gamma pass rate) radiochromic film at 3% agreement/3 mm distance to agreement. Data were separated by institution, model of linac, and treatment protocol (intensity-modulated radiation therapy [IMRT] vs volumetric modulated arc therapy [VMAT]). A total of 97% of OSLDs, 98% of ion chambers, and 93% of films were within the confidence limits; measurements were found outside these limits by a maximum of 4%, < 1%, and < 1%, respectively. Data were consistent despite institutional differences in OSLD reading equipment and radiochromic film calibration techniques. Results from this test may be used by clinics for data comparison. Areas of improvement were identified in the end-to-end protocol that can be implemented in an updated version. The consistency of our data demonstrates the reproducibility and ease-of use of such tests and suggests a potential role for their use in broad end-to-end QA initiatives.

PMID- 29571936 TI - Early Results of Extreme Hypofractionation Using Stereotactic Body Radiation Therapy for High-risk, Very High-risk and Node-positive Prostate Cancer. AB - AIMS: Stereotactic body radiotherapy (SBRT) in low- and intermediate-risk prostate cancer has shown encouraging results. However, its use in high-risk patients is limited due to lack of data regarding adequate radiotherapy dose, need for pelvic nodal treatment and androgen deprivation therapy. Herein we report our experience of SBRT in this subgroup. MATERIALS AND METHODS: Analysis of a prospectively maintained database of 68 consecutive patients of the National Comprehensive Cancer Network (NCCN) high-risk, very high-risk and node-positive adenocarcinoma prostate treated with SBRT was undertaken. All patients were treated with rotational intensity-modulated radiotherapy with daily image guidance. The dose delivered to the prostate and gross node was 35-37.5 Gy in 5 alternate day fractions. Node-positive patients received 25 Gy to pelvic nodal regions until the common iliac nodes. Treatment was delivered in 7-10 days. All patients received long-term androgen deprivation therapy (79% medical and 21% surgical). RESULTS: Most patients (65%) had a Gleason score >= 8. The median prostate-specific antigen was 42. Twenty patients were high risk (30%), 11 (16%) very high risk and 37 (54%) node positive. No acute Radiation Therapy Oncology Group grade >= 3 genitourinary or gastrointestinal toxicity was noted. Acute grade 2 genitourinary and gastrointestinal toxicity were 12% and 3%, respectively. Late grade 3 genitourinary and gastrointestinal toxicity was 3% and 0%, respectively. There was no increase in acute or late gastrointestinal toxicity with prophylactic pelvic nodal radiotherapy. Prior transurethral resection of prostate (n = 11) did not increase toxicity. At a median follow-up of 18 months, 97% patients were alive and 94% were biochemically controlled. CONCLUSION: SBRT is safe in the treatment of high-risk, very high-risk and node positive prostate cancer, even with prophylactic pelvic radiotherapy or prior transurethral resection of prostate. Longer follow-up is required to determine efficacy. PMID- 29571938 TI - Trends in childhood height and weight, and socioeconomic inequalities. PMID- 29571937 TI - Socioeconomic inequalities in childhood and adolescent body-mass index, weight, and height from 1953 to 2015: an analysis of four longitudinal, observational, British birth cohort studies. AB - BACKGROUND: Socioeconomic inequalities in childhood body-mass index (BMI) have been documented in high-income countries; however, uncertainty exists with regard to how they have changed over time, how inequalities in the composite parts (ie, weight and height) of BMI have changed, and whether inequalities differ in magnitude across the outcome distribution. Therefore, we aimed to investigate how socioeconomic inequalities in childhood and adolescent weight, height, and BMI have changed over time in Britain. METHODS: We used data from four British longitudinal, observational, birth cohort studies: the 1946 Medical Research Council National Survey of Health and Development (1946 NSHD), 1958 National Child Development Study (1958 NCDS), 1970 British Cohort Study (1970 BCS), and 2001 Millennium Cohort Study (2001 MCS). BMI (kg/m2) was derived in each study from measured weight and height. Childhood socioeconomic position was indicated by the father's occupational social class, measured at the ages of 10-11 years. We examined associations between childhood socioeconomic position and anthropometric outcomes at age 7 years, 11 years, and 15 years to assess socioeconomic inequalities in each cohort using gender-adjusted linear regression models. We also used multilevel models to examine whether these inequalities widened or narrowed from childhood to adolescence, and quantile regression was used to examine whether the magnitude of inequalities differed across the outcome distribution. FINDINGS: In England, Scotland, and Wales, 5362 singleton births were enrolled in 1946, 17 202 in 1958, 17 290 in 1970, and 16 404 in 2001. Low socioeconomic position was associated with lower weight at childhood and adolescent in the earlier-born cohorts (1946-70), but with higher weight in the 2001 MCS cohort. Weight disparities became larger from childhood to adolescence in the 2001 MCS but not the earlier-born cohorts (pinteraction=0.001). Low socioeconomic position was also associated with shorter height in all cohorts, yet the absolute magnitude of this difference narrowed across generations. These disparities widened with age in the 2001 MCS (pinteraction=0.002) but not in the earlier-born cohorts. There was little inequality in childhood BMI in the 1946-70 cohorts, whereas inequalities were present in the 2001 cohort and widened from childhood to adolescence in the 1958-2001 cohorts (pinteraction<0.05 in the later three cohorts but not the 1946 NSHD). BMI and weight disparities were larger in the 2001 cohort than in the earlier-born cohorts, and systematically larger at higher quantiles-eg, in the 2001 MCS at age 11 years, a difference of 0.98 kg/m2 (95% CI 0.63-1.33) in the 50th BMI percentile and 2.54 kg/m2 (1.85-3.22) difference at the 90th BMI percentile were observed. INTERPRETATION: Over the studied period (1953-2015), socioeconomic-associated inequalities in weight reversed and those in height narrowed, whereas differences in BMI and obesity emerged and widened. These substantial changes highlight the impact of societal changes on child and adolescent growth and the insufficiency of previous policies in preventing obesity and its socioeconomic inequality. As such, new and effective policies are required to reduce BMI inequalities in childhood and adolescence.

AB - It was previously reported that normobaric oxygen therapy (NBO) significantly affected T2*-weighted imaging in a mouse model of intracerebral hemorrhage (ICH). However, it is unclear whether a similar phenomenon exists in large volume ICH as seen in human pathology. We investigated the effects of NBO on T2*-weighted images in a pig model of ICH. Our data show that NBO makes disappear a peripheral crown of the hematoma, which in turn decreases the apparent volume of ICH by 18%. We hypothesized that this result could be translated to ICH in human, and subsequently could lead to inaccurate diagnostic. PMID- 29571940 TI - Inhibiting core fucosylation attenuates glucose-induced peritoneal fibrosis in rats. AB - Ultrafiltration failure is a major complication of long-term peritoneal dialysis, resulting in dialysis failure. Peritoneal fibrosis induced by continuous exposure to high glucose dialysate is the major contributor of ultrafiltration failure, for which there is no effective treatment. Overactivation of several signaling pathways, including transforming growth factor-beta1 (TGF-beta1) and platelet derived growth factor (PDGF) pathways, contribute to the development of peritoneal fibrosis. Therefore, simultaneously blocking multiple signaling pathways might be a potential novel method of treating peritoneal fibrosis. Previously, we showed that core fucosylation, an important posttranslational modification of the TGF-beta1 receptors, can regulate the activation of TGF-beta1 signaling in renal interstitial fibrosis. However, it remains unclear whether core fucosylation affects the progression of peritoneal fibrosis. Herein, we show that core fucosylation was enriched in the peritoneal membrane of rats accompanied by peritoneal fibrosis induced by a high glucose dialysate. Blocking core fucosylation dramatically attenuated peritoneal fibrosis in the rat model achieved by simultaneously inactivating the TGF-beta1 and PDGF signaling pathways. Next the protective effects of blocking core fucosylation and imatinib (a selective PDGF receptor inhibitor) on peritoneal fibrosis were compared and found to exhibit a greater inhibitory effect over imatinib alone, suggesting that blocking activation of multiple signaling pathways may have superior inhibitory effects on the development of peritoneal fibrosis. Thus, core fucosylation is essential for the development of peritoneal fibrosis by regulating the activation of multiple signaling pathways.

AB - Despite worldwide prevalence of superficial mycoses, the immune response in dermatophytosis has scarcely been investigated. In this study, we developed a model of superficial skin infection in C57BL/6 mice with Microsporum canis, a highly prevalent human pathogen. This model mimics mild inflammatory human dermatophytosis, characterized by neutrophil recruitment and fungal invasion limited to the epidermis and exhibits the establishment of a specific T helper type 17 immune response during infection. By using IL-17RA- or IL-17A/F-deficient mice we showed that, in the absence of a functional IL-17 pathway, M. canis extensively colonizes the epidermis and promotes an exaggerated skin inflammation and a shift to an IFN-gamma-mediated (T helper type 1) response. IL-17 signaling was not involved in neutrophil influx to skin or fungal invasion to deeper tissues. Finally, this study shows that skin langerin-expressing cells contribute to the antifungal T helper type 17 response in vivo. In conclusion, these data directly show a dual function of IL-17 cytokines in dermatophytosis by controlling superficial infection and down-modulating a T helper type 1 antifungal response.

AB - Presence of the CD200 immune check-point inhibitor at the feto-maternal interface is linked to prevention of spontaneous abortion in mice and humans. In human missed abortions (MA), absence of Th17-driven inflammation has been attributed to expression of villus trophoblast CD200 quantified using immunohistochemistry. While rapid aneuploidy (QF-PCR) testing linked low CD200 to pregnancy failure, data showing normal VT CD200 in first trimester normal pregnancy and in abortion of chromosomally abnormal embryos has not been demonstrated. The present report shows normal CD200 in a 7 week gestation termination with normal male QF-PCR and in a 10 week male trisomy 18 MA.

PMID- 29571946 TI - Nilotinib in locally advanced pigmented villonodular synovitis: a multicentre, open-label, single-arm, phase 2 trial. AB - BACKGROUND: Pigmented villonodular synovitis (alternatively known as diffuse-type giant cell tumour) is a rare, locally aggressive tumour driven by a specific translocation resulting in the overexpression of colony-stimulating factor 1 (CSF1). CSF1 receptor (CSF1R) inhibitors (ie, tyrosine kinase inhibitors and antibodies) induce a response in patients with pigmented villonodular synovitis. We investigated the safety and efficacy of a CSF1R tyrosine kinase inhibitor, nilotinib, in patients with locally advanced non-resectable pigmented villonodular synovitis. METHODS: In this phase 2, open-label, single-arm study, we enrolled patients from 11 cancer centres of hospitals in four countries (France, Netherlands, Italy, and Australia). Eligible patients were aged at least 18 years with a WHO performance status of 2 or less, and histologically confirmed progressive or relapsing pigmented villonodular synovitis that was inoperable, or resectable only with mutilating surgery. Patients received oral nilotinib (400 mg twice per day) until disease progression, unacceptable toxicity, or completion of 1 year of treatment. The primary endpoint was the proportion of patients who were progression free at 12 weeks, which was centrally assessed according to Response Evaluation Criteria in Solid Tumors version 1.1. Analyses were by modified intention to treat (ie, all patients with no major protocol violations who were treated with nilotinib for at least 3 weeks were included). All participants who received at least one dose of study drug were included in the safety analyses. This study is registered with ClinicalTrials.gov, number NCT01261429, and the results presented here are the final analysis of the trial. FINDINGS: Between Dec 15, 2010, and Sept 28, 2012, we enrolled 56 patients with pigmented villonodular synovitis and treated them with nilotinib. Five (9%) patients discontinued study treatment before week 12; therefore, 51 patients were evaluable for the primary endpoint at 12 weeks. The estimated proportion of patients who were progression free at 12 weeks was 92.6% (95% credible interval 84.3-97.9). 54 (96%) of 56 patients had a treatment-related adverse event. Six (11%) of 56 patients had at least one grade 3 treatment-related adverse event (headache, dizziness, and hepatic disorders [n=1], pruritus and toxidermia [n=1], diarrhoea [n=1], increased gamma-glutamyl transferase concentration [n=1], anorexia [n=1], and increased headache [n=1]). No grade 4 or 5 adverse events were reported. One patient had a treatment-related serious adverse event (toxidermia) and two patients had serious adverse events not considered to be related to the study drug (borderline ovarian tumour [n=1] and pilonidal cyst excision [n=1]). INTERPRETATION: More than 90% of patients with locally advanced unresectable progressive pigmented villonodular synovitis achieved disease control with 12 weeks of nilotinib treatment. These results indicate that CSF1R tyrosine kinase inhibitors have anti-tumour activity with manageable toxicity in patients with inoperable progressive pigmented villonodular synovitis. Randomised trials investigating the efficacy of nilotinib for patients with unresectable pigmented villonodular synovitis are warranted.

PMID- 29571948 TI - Neurological outcome at 6 and 12 months corrected age in hospitalised late preterm infants -a prospective study. AB - Late preterm infants (34-0/7 to 36-6/7 weeks" gestation) account for 10-20% of NICU admissions and are at increased risk for morbidity and mortality. Although they are prone to developmental delays, reports on neurological outcome during the first 2 years of life are scarce. The aim of the study was to assess neurological/neuromotor outcome in high risk late preterm infants at 6 and 12 months corrected age and the change in neurological scores over time, and to identify factors associated with the neurological outcome. The Hammersmith Infant Neurological Examination was performed in a cohort of 157 late preterm infants admitted in the NICU. The infants were examined at 6 and 12 months corrected age respectively and scored with the optimality score system including 26 items assessing cranial nerve function, posture, movements, tone and reflexes. Also parents reported neurological milestones in the follow up visit. Infants at 6 months had a global score of 59 (47-76) and optimal scores achieved in 25.4%. At 12 months they had a global score of 70 (58-78) and achieved optimal scores in 63.2%. The subscores of posture, tone and reflexes gradually increased from 6 to 12 months corrected age. Being born small for gestational age was the only factor that adversely influenced HINE score at 6 and 12 months. At 12 months 58.5% achieved independent walking. High risk late preterm infants have suboptimal HINE scores at 6 and 12 months of age, suggesting a need for closer follow up and early intervention programs. PMID- 29571949 TI - Hypoxia-induced HMGB1 expression of HCC promotes tumor invasiveness and metastasis via regulating macrophage-derived IL-6. AB - Hypoxia is associated with the progression of hepatocellular carcinoma through promotion of spontaneous metastasis but the mechanism remains unclear. Here, we hypothesis that tumor cell-derived HMGB1 orchestrates macrophages infiltration and promotes metastasis of HCC via enhancing macrophage-secreted IL-6 under hypoxia. HMGB1 expression was robustly exacerbated in tumors of HCC patients with PVTT. Meanwhile, hypoxia exposure gave rise to HMGB1 expression in hepatoma cells of human and mouse in a HIF-1alpha-dependent manner and subsequently induced the infiltration and reprogramming of macrophages to augment the expression of Il-6. Further study demonstrated macrophage-derived IL-6 enhanced the invasiveness and metastasis of murine HCC cells. Therefore, our study provides a novel understanding of the relationship between tumor cells and tumor associated macrophages (TAMs) in the context of hypoxia. PMID- 29571950 TI - Aurora A regulates the architecture of the Golgi apparatus. AB - The Golgi apparatus plays roles in cell polarity, directional cell migration, and bipolar spindle assembly, as well as the secretary pathway. In addition, recent studies have suggested the Golgi-dependent control of mitotic entry. We studied the role of the centrosomal kinase Aurora A in maintaining the Golgi apparatus. Knockdown of Aurora A resulted in Golgi dispersal during interphase. Golgi dispersal was also induced by a selective Aurora A inhibitor, MLN8237. Conversely, overexpression of Aurora A led to tightly packed Golgi apparatus during interphase. Knockdown or inhibition of Aurora A had little or no effect on Golgi vesiculation during mitosis. By synchronizing cell division, we studied whether mitosis was required to induce Golgi dispersal during interphase. Aurora A inhibition induced aberrant mitotic spindle and Golgi dispersal only after mitosis. However, the cells treated with the inhibitor MLN8237 at earlier cell cycle stages (wherein the cells remained undivided) had a normal Golgi architecture. Knockdown or inhibition of Aurora A also led to aberrant integrity of centrosome and Golgi apparatus during interphase. These results suggest that Aurora A activity is involved in the maintenance of Golgi architecture and the relationship between the Golgi apparatus and centrosome. PMID- 29571951 TI - [Benign aggressive vascular anomalies in children]. AB - Superficial vascular anomalies constitute a large group of malformative and tumoral conditions developed from all types of vessels. Vascular tumors are the result of cellular hyperplasia, whereas vascular malformations (VMs) are constituted of dysplastic vessels. The classification from International Society for the Study of Vascular Anomalies (ISSVA) is based on this pathogenic difference. The most common vascular tumor is infantile hemangioma, which treatment, when necessary, is propranolol. Congenital hemangiomas and tumors that might be complicated with Kasabach-Merritt phenomenon, i.e. deep thrombocytopenia, are much rarer. Management of Kasabach-Merritt phenomenon is now largely based on sirolimus. Low-flow VMs include capillary, venous and lymphatic malformations; arteriovenous malformations are high-flow malformations. These different types of VMs might be combined. Currently, there is an increasing work in delineating the different entities based on molecular findings. Treatment of VMs depends on the impairment linked to them, and is decided case by case, in pluridisciplinary consultations. Interventional treatments, especially surgery and sclerotherapy, are usually partially efficient, and management of patients with VMs increasingly involves medical drugs. First-line treatment of coagulation disorders associated with venous malformations is based on low molecular weight heparin; sirolimus seems efficient in hemorrhagic complications refractory to usual treatment. Sirolimus is about to become the standard treatment in painful inflammatory manifestations of mixed and/or complicated lymphatic malformations. PMID- 29571952 TI - An Evaluation of Trends in Patient and Public Awareness of IR. AB - PURPOSE: To evaluate patient and public awareness of interventional radiology (IR). MATERIALS AND METHODS: This single-center study prospectively administered voluntary paper surveys to 80 patients in an academic hospital radiology waiting room. Separate, Internet-based surveys were administered to the general public. Additionally, Internet metadata were used to evaluate relative search engine activity and IR-related news coverage compared with similar procedural specialties. RESULTS: 65% of radiology department outpatients had no prior knowledge of IR. Of the general population surveyed, 72% could not identify an interventional radiologist as a physician. Relative annual IR-related Google search volumes peaked in 2004 and were at their nadir in 2011. After normalizing for number of practicing physicians, IR was the subject of substantially fewer Google searches than similar specialties (15.9% of urology volumes, 27.9% of cardiology volumes, and 39.0% of vascular surgery volumes). Between 2006 and 2016, IR had a similar rate of annual increase in the volume of Internet news results as similar medical specialties, although the volumes reached by IR in 2016 were obtained by more established fields, such as cardiology, in 2011. CONCLUSIONS: These data provide metrics of current and historical awareness trends in IR, which demonstrate low patient and public awareness. The findings of this study may help guide future efforts to promote patient and public awareness of IR. PMID- 29571953 TI - Reversing the effects of 2% Lidocaine: A randomized controlled clinical trial. AB - OBJECTIVES: Prolonged soft tissue anesthesia following a dental appointment is a complaint that is frequently reported by patients. Soft tissue anesthesia generally exceeds the duration of pulpal anesthesia by a few hours. This can lead to difficulties with smiling, drinking, speaking and lip/cheek biting following dental appointments. Phentolamine Mesylate (PM) is a pharmacological agent capable of reducing the duration of soft tissue anesthesia following dental treatments. Many clinical trials supporting its efficacy have used sham injections compared to injections with PM. The present study aims to evaluate the effect of PM on the duration of soft tissue anesthesia compared to a control injection of saline water. METHODS: This randomized controlled trial recruited 40 participants above 18 years of age. Following an inferior alveolar nerve block using 1.8 ml of Lidocaine 2%, 1:100 000 epinephrine, participants were randomized into one of 2 groups. The test group received an injection of 0.4 mg PM (OraVerse). Participants in the control group received an injection of sterile saline water. Participants were trained in self-assessing their anesthesia, which they did until return to normal sensation. RESULTS: Thirty-six participants completed the study. PM significantly reduced the duration of soft tissue anesthesia in the lower lip (104 vs 170 min, p = .001), and tongue (83 vs 134 min, p = .004) compared to the control injection. No serious adverse events were encountered. The only adverse events observed were post-operative pain and discomfort. CONCLUSIONS: Phentolamine Mesylate hastens the return to normal soft tissue sensation and function by approximately one hour compared to a control injection of water. CLINICAL SIGNIFICANCE: Phentolamine Mesylate can be considered a safe and effective way of reducing the duration of soft tissue anesthesia following a dental appointment. This controlled clinical trial is registered at the National Institutes of Health (ClinicalTrials.gov) #NCT02861378. PMID- 29571955 TI - Eye movement parameters and cognitive functions in Parkinson's disease patients without dementia. AB - BACKGROUND: Cognitive deficits and eye movement abnormalities have been demonstrated to be detectable early clinical manifestations of Parkinson's disease. Understanding the relationship between these phenotypes may yield insight into the underlying anatomical pathways, assisting in the search for simple non-invasive markers of early neurodegeneration. OBJECTIVE: To explore the correlations between eye movement parameters with multi-domain cognitive functions in patients suffering from Parkinson's disease without dementia. METHOD: This is a cross-sectional case-control study of Parkinson's disease patients without dementia. Participants underwent global and domain-specific cognitive tests and an eye-tracking visual search task to characterize eye movement parameters. RESULTS: 62 Chinese Parkinson's disease patients without dementia and 62 sex-, age- and education-matched controls were recruited. The disease group performed worse in multiple cognitive tasks and exhibited a smaller saccadic amplitude. Negative correlations between the eye fixation duration and performance in semantic verbal fluency, verbal and visual recognition memory tasks were observed, though there was no moderation effect on the correlations due to the presence of Parkinson's disease. A common cholinergic deficit in the temporal and parietal regions may account for the observed correlations. The lack of association with predominantly frontal-executive tasks may suggest specificity of these correlations. CONCLUSION: Prolonged visual fixation duration is correlated with poorer performance in semantic verbal fluency, verbal and visual recognition memory tasks in Parkinson's disease patients without dementia, although these correlations are not specific. The clinical utility of eye movement parameters as an early marker for cognitive decline in Parkinson's disease warrants further exploration in longitudinal studies. PMID- 29571954 TI - Antimicrobial efficacy of an apical negative pressure root canal irrigation system against intracanal microorganisms. AB - OBJECTIVES: The effect of irrigation time on the antimicrobial efficacy of an apical negative pressure irrigation system was examined in vitro, followed by validation of the antimicrobial effect in vivo using the identified optimal irrigation time. METHODS: For the in vitro experiment, 44 extracted premolars were decoronated, instrumented, autoclaved and inoculated with Enterococcus faecalis (ATCC 29212) for 21 days. Four teeth were used as positive control, without irrigation. Each of the remaining 40 teeth was irrigated with 2.5% NaOCl, delivered via the EndoVac MacroCannula for 10 s, and subsequently via the EndoVac MicroCannula for 15, 30, 45, 60 or 90 s per canal, respectively (N = 8). After irrigation, microbial samples were collected, transferred to BHI broth and incubated for counting of bacterial colony forming units (CFUs). Based on the in vitro results, 8.25% NaOCl was delivered via the EndoVac MicroCannula for 60 s, during root canal treatment of 20 human subjects presented with apical periodontitis. Microbial samples retrieved in vivo prior to canal instrumentation (S0), after chemomechanical debridement (S1) and after irrigation with EndoVac (S2) were cultured in an anaerobic chamber for 7 days for CFU evaluation. RESULTS: Compared with the control, irrigation significantly reduced bacterial populations (p < .05). Irrigation delivery via the EndoVac demonstrated improved antibacterial efficacy with increased irrigation time (p < .05). Samples retrieved from canals after NaOCl delivery in vivo with the EndoVac for 60 s were all culture-negative. CONCLUSIONS: Microbial elimination may be achieved with 8.25% NaOCl delivered via the EndoVac apical negative pressure irrigation device for 60 s. CLINICAL SIGNIFICANCE: With the use of the EndoVac apical negative pressure irrigant delivery system, optimal elimination of the intracanal bacterial load can only be achieved when sodium hypochlorite is delivered via the MicroCannula for at least 60 s per canal. PMID- 29571956 TI - The succession of the plant community on a decontaminated radioactive meadow site. AB - Long-term observation of the succession in a plant community is considered a fundamental unit used to investigate the expected consequences of soil contamination by radionuclides and to understand restoration of technogeneously disturbed ecosystems. The development of arboreal willow meadow under remediation of a radioactively contaminated site has been studied for half a century. Succession stages in the formation of the de novo community were noted. Changes in the floristic composition, soil structure as well as radionuclide activity concentrations in topsoil were registered on each step. Technical recultivation of the area including covering radioactive wastes with a mixture of sand and gravel led to lower the radiation levels and was suitable for decontamination during first 5-8 years. This allowed the community to develop with maximal effectiveness on the initial steps. Than the covering layer lost its barrier functions but no adverse effects at dose rates up to 150 MUGy/h on completion of the community formation were registered. Radioecological conditions and changes in the plant community development were registered simultaneously on the area studied that makes possible to follow main doseforming radionuclides migration and to determine main steps of the succession. The study results is a practical demonstration that edaphic niches, climatic conditions and soenotic relationships between plants play a more important role in the evolution of the studied community than the contamination type and radiation exposure levels.

PMID- 29571958 TI - Transplantation of dedifferentiated fat cell-derived micromass pellets contributed to cartilage repair in the rat osteochondral defect model. AB - BACKGROUND: Mature adipocyte-derived dedifferentiated fat (DFAT) cells possesses the ability to proliferate effectively and the potential to differentiate into multiple linages of mesenchymal tissue; similar to adipose-derived stem cells (ASCs). The purpose of this study is to examine the effects of DFAT cell transplantation on cartilage repair in a rat model of osteochondral defects. METHODS: Full-thickness osteochondral defects were created in the knees of Sprague-Dawley rats bilaterally. Cartilage-like micromass pellets were prepared from green fluorescent protein (GFP)-labeled rat DFAT cells and subsequently transplanted into the affected right knee of these rats. Defects in the left knee were used as a control. Macroscopic and microscopic changes of treated and control defects were evaluated up to 12 weeks post-treatment with DFAT cells. To observe the transplanted cells, sectioned femurs were immunostained for GFP and type II collagen. RESULTS: DFAT cells formed micromass pellets expressing characteristics of immature cartilage in vitro. In the DFAT cell-transplanted limbs, the defects were completely filled with white micromass pellets as early as 2 weeks post-treatment. These limbs became smooth at 4 weeks. Conversely, the defects in the control limbs were still not repaired by 4 weeks. Macroscopic ICRS scores at 2 and 4 weeks were significantly higher in the DFAT cells-transplanted limbs compared to those of the control limbs. The modified O'Driscol histological scores for the DFAT cell-transplanted limbs were significantly higher than those of the control limbs at corresponding time points. GFP-positive DAFT cells were detected in the transplanted area at 2 weeks but hardly visible at 12 weeks post operation. CONCLUSIONS: Transplantation of DFAT cell-derived micromass pellets contribute to cartilage repair in a rat osteochondral defect model. DFAT cell transplantation may be a viable therapeutic strategy for the repair of osteochondral injuries. PMID- 29571959 TI - Adaptation reveals unbalanced interaction between numerosity and time. AB - Processing quantities such as the number of objects in a set, size, spatial arrangement and time is an essential means of structuring the external world and preparing for action. The theory of magnitude suggests that number and time, among other continuous magnitudes, are linked by a common cortical metric, and their specialization develops from a single magnitude system. In order to investigate potentially shared neural mechanisms underlying numerosity and time processing, we used visual adaptation, a method which can reveal the existence of a dedicated processing system. We reasoned that cross-adaptation between numerosity and duration would concur with the existence of a common processing mechanism, whereas the absence of cross-adaptation would provide evidence against it. We conducted four experiments using a rapid adaptation protocol where participants adapted to either visual numerosity or visual duration and subsequently performed a numerosity or duration discrimination task. We found that adapting to a low numerosity altered the estimation of the reference numerosity by an average of 5 dots, compared to adapting to a high numerosity. Similarly, adapting to a short duration altered the estimation of the reference duration by an average of 43 msec, compared to adapting to a long duration. In the cross-dimensional adaptation conditions, duration adaptation altered numerosity estimation by an average of 1 dot, whereas there was not sufficient evidence to either support or reject the effect of numerosity adaptation on duration judgments. These results highlight that there are partially overlapping neural mechanisms which are dedicated for processing both numerosity and time. PMID- 29571960 TI - Pathological collecting behavior. PMID- 29571961 TI - Investigating the role of personal and context-related factors in convenience foods consumption. AB - In the scenario of food consumptions, we witness the consumer's growing consideration for the "convenience" attribute. Our study intends to understand the consumer behaviour towards convenience-processed foods by analysing in a single model the role of beliefs, personal traits, social influence and market availability. We applied a Structural Equation Model (SEM) to a representative sample of 426 Italian consumers. The results show a correlation between intention to consume convenience-processed foods and social influence, market availability and several personal traits, suggesting strategies for the development of the convenience food market. PMID- 29571962 TI - Therapeutic plasma exchange: A prospective randomized trial to evaluate 2 strategies in patients with liver failure. AB - OBJECTIVE: To compare two means of performing therapeutic plasma exchange (TPE) in patients with liver failure. METHOD: This open-label monocentric randomized trial, conducted in a single prestigious general healthcare facility, recruited liver failure patients with an indication to receive artificial liver support therapy for TPE. All patients underwent TPE procedures and were administered in a random sequence: heparin-free or systemic heparinization with unfractionated heparin. The primary endpoint was completion of TPE sessions, and the secondary endpoints included the safety and efficacy. RESULTS: In the period of the studying, there were 164 patients being recruited in and underwent total of 398 randomized TPEs: 168 with unfractionated heparin and 230 with heparin-free. In unfractionated heparin group, there were 3 cases (1.79%) being interrupted due to uncontrollable intraoperative pulmonary hemorrhages and gastrointestinal bleeding. In heparin-free group, 228 (99.13%) were completed successfully and 2 of them (0.87%) were switched from heparin-free to unfractionated heparin eventually. No significant differences were found between the two groups for either RRs or IRs (P > 0.05). CONCLUSION: Heparin-free regimen is feasible and safer than systemic heparinization with unfractionated heparin in the process of TPEs in patients with liver failure. PMID- 29571963 TI - First evidence of DAAM1 localization in mouse seminal vesicles and its possible involvement during regulated exocytosis. AB - Dishevelled-associated activator of morphogenesis 1 (DAAM1) is a protein belonging to the formin family, which regulates, together with the small GTPase RhoA, the nucleation and the assembly of actin fibres through Wnt-Dishevelled PCP pathway. Its role has been investigated in essential biological processes, such as cell polarity, movement and adhesion during morphogenesis and organogenesis. In this work, we studied the expression of DAAM1 mRNA and protein by PCR and Western blot analyses and its co-localization with actin in adult mouse seminal vesicles by immunofluorescence. We show that both proteins are cytoplasmic: actin is evident at cell-cell junctions and at cell cortex; DAAM1 had a more diffused localization, but is also prominent at the apical plasmatic membrane of epithelial cells. These findings support our hypothesis of a role of DAAM1 in cytoskeletal rearrangement that occurs during the exocytosis of secretory vesicles, and in particular concerning actin filaments. We were also able to detect DAAM1 and actin association in the smooth muscle cells that surround the epithelium too. In this case, we could only speculate the possible involvement of this formin in muscular cells in the maintenance and the regulation of the contractile structures. The present results strongly suggest that DAAM1 could have a pivotal role in vesicle exocytosis and in the physiology of mouse seminal vesicles.

PMID- 29571966 TI - Effects of the antipsychotics haloperidol, clozapine, and aripiprazole on the dendritic spine. AB - Three types of antipsychotics, typical (e.g. haloperidol), atypical (e.g. clozapine), and dopamine partial agonist (e.g. aripiprazole), are administered for treatment of schizophrenia. These antipsychotics have different efficacy and side-effect profiles. We investigated whether aripiprazole, clozapine, and haloperidol differentially regulate the dendritic spine through the AKT-GSK-3 beta cascade. Dissociated cortical neurons from Sprague-Dawley rats were prepared and cultured for 28 days. Aripiprazole, clozapine, or haloperidol was administered to the rat cortical neurons. The levels of PSD95 protein and AKT-GSK 3 beta cascade-related proteins were investigated by Western blot. The number of spines and PSD95 puncta were investigated by immunofluorescence cell staining. Aripiprazole (1 uM or 10 uM) and clozapine (1 uM) increased the levels of PSD95 protein, the number of spines, phosphorylated Akt Thr308 and Ser473, and phosphorylated GSK-3 beta Ser9. On the other hand, haloperidol (1 uM or 10 uM) or an inappropriate concentration of clozapine (10 uM) decreased them. A GSK inhibitor also increased the levels of PSD-95 protein and caused the same morphology. Aripiprazole, clozapine, and haloperidol differentially regulate the dendritic spine, and this effect may occur through the AKT-GSK-3 beta cascade. Selection and appropriate dose of these antipsychotics may be important for the protection of dendritic spines in patients with schizophrenia. PMID- 29571967 TI - Functional mechanism of ASP5736, a selective serotonin 5-HT5A receptor antagonist with potential utility for the treatment of cognitive dysfunction in schizophrenia. AB - The 5-HT5A receptor is arguably the least understood 5-HT receptor. Despite widespread expression in human and rodent brains it lacks specific ligands. Our previous results suggest that 5-HT5A receptor antagonists may be effective against cognitive impairment in schizophrenia. In this study, using behavioral, immunohistochemical, electrophysiological and microdialysis techniques, we examined the mechanism by which ASP5736, a novel and selective 5-HT5A receptor antagonist, exerts a positive effect in animal models of cognitive impairment. We first confirmed the effect of ASP5736 on cognitive deficits in rats treated subchronically with phencyclidine hydrochloride (PCP) using an attentional set shifting task. Subsequently, we identified 5-HT5A receptors in dopaminergic (DAergic) neurons and parvalbumin (PV)-positive interneurons in the ventral tegmental area (VTA) and in PV-positive interneurons in the medial prefrontal cortex (mPFC). Burst firing of the DAergic cells in the parabrachial pigmental nucleus (PBP) in the VTA, which predominantly project to the mPFC, was significantly enhanced by treatment with ASP5736. In contrast, ASP5736 exerted no significant effect on either the firing rate or burst firing in the DA cells in the paranigral nucleus (PN), that project to the nucleus accumbens (N. Acc.). ASP5736 increased the release of DA and gamma-aminobutyric acid (GABA) in the mPFC of subchronically PCP-treated rats. These results support our hypothesis that ASP5736 might block the inhibitory 5-HT5A receptors on DAergic neurons in the VTA that project to the mPFC, and interneurons in the mPFC, and thereby improve cognitive impairment by preferentially enhancing DAergic and GABAergic neurons in the mPFC. PMID- 29571968 TI - Ocular treatment of choroidal melanoma in relation to the prevention of metastatic death - A personal view. AB - About 50% of patients with choroidal melanoma develop metastatic disease, despite successful eradication of the primary tumor. Patient care is complicated by the fact that we do not know whether ocular treatment ever influences survival and if so in whom. Some authorities believe that metastatic spread is never preventable, because it has always occurred by the time the ocular tumor is detected. Others hold the view that metastatic spread can occur late, at least in some patients, in whom timely and successful treatment is life-saving. Some melanomas never seem to metastasize, even if they reach an advanced stage. It is likely that many patients are undergoing futile enucleation or experiencing severe ocular morbidity and visual loss from excessive radiation safety margins in the hope of living longer. Some of these patients would do better with tumor resection, often rejected because of concerns about iatrogenic tumor dissemination. At the same time, many patients with a small melanoma are being left untreated for years until growth is documented, possibly missing opportunities for prolonging life. Metastatic disease is highly likely when genetic tumor analysis detects monosomy 3, chromosome 8q gain, a class 2 gene expression profile, and/or BAP1 loss. Do these lethal genetic aberrations ever develop while the patient is under observation? If so, can these be predicted by genetic analysis? Do lethal mutations and metastasis ever occur because ocular treatment has failed to eradicate the tumor completely? Answers to these questions would profoundly change the management of patients with uveal melanoma. PMID- 29571969 TI - Efficacy of anterior versus posterior per-oral endoscopic myotomy for treating achalasia: a randomized, prospective study. AB - BACKGROUND AND AIMS: Per-oral endoscopic myotomy (POEM) has been demonstrated to be safe and effective for treating achalasia. Two approaches-anterior myotomy and posterior myotomy-are used during POEM. However, little is known about the comparison between the 2 different approaches. The objective of the study is to compare the safety and short-term efficacy of the 2 approaches for treating achalasia. METHODS: From October 2015 to December 2016, 63 consecutive patients with achalasia without prior treatment or sigmoid-type esophagus were prospectively recruited. They were randomly assigned to an anterior or posterior myotomy group. Clinical data about general characteristics, operative parameters, pre- and postoperative Eckardt score, esophageal manometry results, 24-hour pH test, and adverse events were recorded and compared between the 2 groups. RESULTS: The anterior group included 31 patients and the posterior group 32 patients. All patients underwent POEM successfully, and treatment success (defined as an Eckardt score <=3) was achieved in all patients during a mean follow-up of 15.5 months. Mean Eckardt score, lower esophageal sphincter pressure, and 4-second integrated relaxation pressure were significantly decreased (6.2 +/- 1.3, 37.5 +/- 6.7 mm Hg, and 27.3 +/- 4.9 mm Hg vs .70 +/- .70, 12.8 +/- 2.8 mm Hg, and 11.1 +/- 2.3 mm Hg, respectively; P < .01). There was no significant difference between the 2 groups in terms of general characteristics, treatment success, pre- and postoperative esophageal manometry, Eckardt score, and adverse events (P > .05). CONCLUSIONS: The short-term treatment efficacy, manometry outcomes, and adverse events were comparable between the anterior and posterior myotomy groups. Large-scale studies with long term follow-up are warranted for a more definitive conclusion. (Clinical trial registration number: ChiCTR-ICR-15007211.). PMID- 29571970 TI - Unconventional secretion of viral proteins. AB - Although largely less numerous and characterized than bacterial secreted effectors, several viral virulence factors are secreted by virus infected cells. However, their mode of secretion only starts to be studied at the molecular level. Several of these viral effectors are secreted using an unconventional secretion pathway, i.e. despite the lack of signal sequence. We here review recent results illustrating the diversity of these pathways. In the case of HIV-1 proteins Tat and matrix (p17) proteins, secretion directly takes place at the plasma membrane level following binding to PI(4,5)P2. The secretion of HTLV-I Tax was found to partly rely on exocytic pathway intermediates. The secretion pathways of VP22 of Herpes simplex virus type I and VP40 of the Ebola virus are less well characterized but VP40 can be recruited to the plasma membrane by PI(4,5)P2 that thus appears as a key partner enabling the unconventional secretion of many viral proteins. Several studies indicated that circulating retroviral transactivating proteins Tat and Tax are involved in the development of AIDS and HTLV-I associated myelopathy/tropical spastic paraparesis, respectively. PMID- 29571971 TI - The unconventional secretion of IL-1beta: Handling a dangerous weapon to optimize inflammatory responses. AB - Interleukin 1beta (IL-1beta) is a major mediator of inflammation, with a causative role in many diseases. Unlike most other cytokines, however, it lacks a secretory signal sequence, raising intriguing mechanistic, functional and evolutionary questions. Despite decades of strenuous efforts in many laboratories, how IL-1beta is secreted is still a matter of intense debate. Here, we summarize the different mechanisms and pathways that have been proposed for IL 1beta secretion. At least two of them, namely the endolysosomal vesicle-based and gasdermin D-dependent pathways (types III and I in the recent Rabouille's classification of unconventional protein secretion), can be triggered in monocytes, the main source of IL-1beta in humans, according to the type and strength of the pro-inflammatory stimuli. As during the escalation of human conflicts, monocytes deploy secretory mechanisms of increasing efficiency and dangerousness, shifting from the specific and controlled type III pathway to the much faster release of type I. Thus, the different mechanisms are activated depending on the severity of the conditions, from the self-limiting type III pathways in response of low pathogen load or small trauma, to the uncontrolled responses that underlie autoinflammatory disorders and sepsis. PMID- 29571972 TI - Immunoinformatics approaches to design a novel multi-epitope subunit vaccine against HIV infection. AB - The end goal of HIV vaccine designing requires novel strategies to elicit a strong humoral and cell-mediated immune response. The emergence of drug resistance and the requirement of next line treatment necessitate the finding of the potential and immunogenic vaccine candidate. This study employed a novel immunoinformatics approach to design multi-epitope subunit vaccine against HIV infection. Here, we designed the subunit vaccine by the combination of CTL, HTL and BCL epitopes along with suitable adjuvant and linkers. Physiochemical characterization of subunit vaccine was assessed to ensure its thermostability, theoretical PI, and amphipathic behavior. In further assessment, subunit vaccine was found to be immunogenic with the capability to generate humoral and cell mediated immune response. Further, homology modeling and refinement was performed and the refined modeled structure was used for molecular docking with the immune receptor (TLR-3) present on lymphocyte cells. Consequently, molecular dynamics simulation ensured the molecular interaction between TLR-3 and subunit vaccine candidate. Disulfide engineering was performed by placing the cysteine residues in the region of high mobility to enhance the vaccine stability. At last, in silico cloning was performed to warrant the translational efficiency and microbial expression of the designed vaccine. PMID- 29571973 TI - Options for design of real-world impact studies of single-dose vaccine schedules. AB - Based on existing evidence for efficacy, savings, and advantages in delivery, some countries may elect to pilot or roll out single-dose human papillomavirus (HPV) vaccination (instead of, or in combination with, two-dose) in advance of a WHO policy decision. Accelerated evidence of population-based effectiveness (hereafter referred to as overall effectiveness, OE) of one-dose vaccine programs could be gained through regular surveys of HPV prevalence in young women before and after vaccination introduction. In order to offer the earliest information on OE, one-dose HPV vaccination should target one or more birth cohorts as close as possible to the age when sexual activity most often starts in a given population. A catch-up one-dose vaccination program of girls up to 18 years of age who would have been too old to profit from the introduction of a routine HPV vaccination program in preadolescents would minimize the interval between vaccination and the possibility to monitor vaccination impact in young women. In addition, catch-up is especially desirable in low- and middle-income countries with little access to screening as "missed" cohorts may face high risk of cervical cancer death. HPV prevalence should be firstly monitored in age groups of women who may already be sexually active but still reluctant to admit it and to accept vaginal examination for the collection of cervical cells. Hence, HPV testing from urine samples, for which good concordance with cervical cells has been proven, offers a feasible approach to assess periodically vaccine OE in representative samples of 17-20 year-old women. This type of observational study would greatly benefit from the presence of a population census and the creation of a vaccination registry. A real-world demonstration of OE of the new schedule would complement the findings of ongoing clinical trials and immunogenicity studies on the efficacy of single dose HPV vaccination. PMID- 29571975 TI - Asleep at the automated wheel-Sleepiness and fatigue during highly automated driving. AB - Due to the lack of active involvement in the driving situation and due to monotonous driving environments drivers with automation may be prone to become fatigued faster than manual drivers (e.g. Schomig et al., 2015). However, little is known about the progression of fatigue during automated driving and its effects on the ability to take back manual control after a take-over request. In this driving simulator study with No=o60 drivers we used a three factorial 2o*o2o*o12 mixed design to analyze the progression (12o*o5omin; within subjects) of driver fatigue in drivers with automation compared to manual drivers (between subjects). Driver fatigue was induced as either mainly sleep related or mainly task related fatigue (between subjects). Additionally, we investigated the drivers' reactions to a take-over request in a critical driving scenario to gain insights into the ability of fatigued drivers to regain manual control and situation awareness after automated driving. Drivers in the automated driving condition exhibited facial indicators of fatigue after 15 to 35omin of driving. Manual drivers only showed similar indicators of fatigue if they suffered from a lack of sleep and then only after a longer period of driving (approx. 40omin). Several drivers in the automated condition closed their eyes for extended periods of time. In the driving with automation condition mean automation deactivation times after a take-over request were slower for a certain percentage (about 30%) of the drivers with a lack of sleep (Mo=o3.2; SDo=o2.1os) compared to the reaction times after a long drive (Mo=o2.4; SDo=o0.9os). Drivers with automation also took longer than manual drivers to first glance at the speed display after a take-over request and were more likely to stay behind a braking lead vehicle instead of overtaking it. Drivers are unable to stay alert during extended periods of automated driving without non-driving related tasks. Fatigued drivers could pose a serious hazard in complex take-over situations where situation awareness is required to prepare for threats. Driver fatigue monitoring or controllable distraction through non-driving tasks could be necessary to ensure alertness and availability during highly automated driving. PMID- 29571974 TI - An interactive contouring module improves engagement and interest in radiation oncology among preclinical medical students: Results of a randomized trial. AB - PURPOSE: Studies have shown significant gaps in knowledge of radiation therapy among medical students and primary care providers. The goal of this study was to evaluate the effect of an interactive contouring module on knowledge and interest in radiation oncology among preclinical medical students. METHODS AND MATERIALS: Second-year medical students at the University of California, San Diego were randomized to participate in an interactive contouring exercise or watch a traditional didactic lecture on radiation oncology. Participants completed knowledge tests and surveys at baseline, immediately following the exercise, and 3 months later. Statistical analysis included Wilcoxon signed-rank test for pre- and posttest comparisons and Wilcoxon rank sum test for comparison between groups. RESULTS: Forty-three medical students participated in the trial (21 in the didactic group; 22 in the contouring group). Students completing the contouring module demonstrated similar overall knowledge improvement compared with the traditional didactic group (+8.6% vs +6.6%, not significant) but endorsed greater engagement on a 5-point Likert-type scale (3.10 vs 3.76, P = .02). At 3-month follow-up, there was a nonsignificant trend toward improved overall knowledge in the contouring group (43% vs 51%, P = .10), with a significance difference in a subset of questions on knowledge of the process of radiation therapy as well as side effects (51% vs 75%, P = .002). Students in the contouring group demonstrated more interest in pursuing a clinical radiation oncology rotation (2.52 vs 3.27, P = .01). CONCLUSIONS: Use of an interactive contouring module was an effective method to teach preclinical medical students about radiation oncology, with no significant difference in knowledge gained compared with a traditional didactic lecture; however, higher engagement among students completing the contouring module led to improved retention of knowledge of radiation side effects and greater interest in radiation oncology. These data suggest a potential benefit of integrating an interactive radiation oncology module into the preclinical medical school curriculum. PMID- 29571976 TI - The effect of vitamin C and/or E supplementations on type 2 diabetic adult males under metformin treatment: A single-blinded randomized controlled clinical trial. AB - BACKGROUND AND AIM: Recently, there has been an increasing interest in the influence of antioxidant vitamins on the efficacy of oral hypoglycemic therapy in type 2 diabetic patients (T2DM). This single-blinded randomized controlled clinical trial aimed to investigate the effect of vitamin C and/or E supplementation on the efficacy of oral hypoglycemic therapy in T2DM Palestinian male patients from the Gaza Strip. METHODS: Forty T2DM male patients aged 40-60 years on metformin treatment were randomly divided into four groups, each group received an additional one of the following daily oral supplements for 90 days: placebo; vitamin C; vitamin E and vitamin C plus vitamin E. After overnight fasting, venous blood specimens were collected from all individuals into K3-EDTA tubes and serum tubes for measuring the biochemical and hematological parameters of the study at baseline and after 90 days of vitamins supplementation. RESULTS: The results revealed that vitamin C and/or E improve fasting blood sugar (FBS), HbA1c, lipid profile, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), reduced glutathione (GSH); and Quantitative Insulin Sensitivity Check Index (QISCI) compared with diabetic patients group that received placebo. CONCLUSION: This study provided additional evidence on the beneficial effects of supplementing antioxidant vitamins in T2DM which could improve the clinical condition and attenuate or prevent diabetic pathogenesis and complications that, secondly to poor glycemic control, could attribute to the imbalance between the decline in the endogenous antioxidants and increasing production of the reactive oxygen species leading to the oxidant-mediated damage present in the diabetic context. PMID- 29571977 TI - Non-alcoholic fatty liver disease and associated dietary and lifestyle risk factors. AB - Nonalcoholic fatty liver disease (NAFLD) has emerged as the most common chronic liver disease worldwide with a reported prevalence ranging 20-30% depending on the studied populations. The high prevalence of NAFLD is probably due to the contemporary epidemics of obesity, unhealthy dietary pattern, and sedentary lifestyle. NAFLD patients are at increased risk of cardiovascular and liver related mortality. The cornerstone of any treatment regimen for patients with NAFLD is lifestyle modification focused on weight loss, exercise, and improving insulin sensitivity. The purpose of this review is to outline the effect of diet and lifestyle factors on developing NAFLD. PMID- 29571978 TI - Hypertension and diabetes mellitus as a predictive risk factors for stroke. AB - BACKGROUND: Stroke is becoming a major challenge in healthcare systems, and this has necessitated the study of the various risk factors. As the number of people with hypertension, diabetes mellitus and obesity increases, the problem is expected to worsen. This review paper evaluates what can be done to eliminate or reduce the risk of stroke. OBJECTIVE: The aim of the research is to evaluate the risk factors for stroke. The paper also aims to understand how these risks can be handled to avoid incidences of stroke. METHOD: Published clinical trials of stroke risk factors studies were recognised by a search of EMBASE and MEDLINE databases with keywords hypertension, blood pressure, diabetes mellitus, stroke or cardiovascular disease, or prospective study, and meta-analysis. RESULTS: The findings of this review are that the prevention of stroke starts with identifying risk factors for stroke, most of the patients diagnosed with stroke have various risk factors. Consequently, it is a very significant to identify all the risk factors for stroke as well as to teach the patient how to dominate them. CONCLUSION: after summarising all the studies mentioned in the paper, it can be established that hypertension and diabetes mellitus are a stroke risk factors and correlated in patients with atherosclerosis. PMID- 29571979 TI - Effects of patchouli and cinnamon essential oils on biofilm and hyphae formation by Candida species. AB - The prevalence and fatality rates with biofilm-associated candidal infections have remained a challenge to the medical fraternity despite major advances in the field of antifungal therapy. Traditionally, essential oils (EOs) from the aromatic plants have been found to be excellent therapeutic agents to treat fungal ailments. The present study explores the antivirulent and antibiofilm effects of under explored leaf EOs of Indian patchouli EO extracted from Pogostemon heyneanus (PH), Indian cassia from Cinnamomum tamala (CT) and camphor EO from C. camphora (CC) against Candida species. The EOs were investigated for its efficacy to disrupt the young and preformed Candida spp. biofilms and to inhibit the yeast to hyphal transition, a hallmark virulent trait of C. albicans. The ability of these EOs to inhibit metabolically active cells was assessed through XTT assay. Of these three EOs, CT EO showed enhanced biofilm inhibition than others and hence it was further selected to study its biomass inhibition potential and exopolysaccharide layer disruption ability. The CT EO reduced the biomass of the preformed biofilms of all three Candida strains, which was supported by confocal microscopy. It also disrupted the exopolysaccharide layer of the Candida strains as shown by scanning electron microscopy. The present findings validate the effectiveness of EOs against the virulence of Candida spp. and emphasize the pharmaceutical potential of several native but yet unexplored wild aromatic plants in the prospect of therapeutic application. PMID- 29571980 TI - Brought Down by a Mosquito? West Nile Virus Encephalitis. PMID- 29571981 TI - Giardipain-1, a protease secreted by Giardia duodenalis trophozoites, causes junctional, barrier and apoptotic damage in epithelial cell monolayers. AB - The adhesion of Giardia duodenalis trophozoites to intestinal epithelial cells allows the onset and maintenance of giardiasis. During these interactions, epithelial cells can be committed to apoptosis by enzymes secreted by the parasites, including cysteine proteases that are increasingly identified as virulence factors in parasitic protozoa. In this work, a monoclonal antibody (mAb1G3) raised against G. duodenalis surface components was found to react with a 25 kDa protein expressed in the cell surface and flagella of G. duodenalis trophozoites. When trophozoites expressing this protein were cultured with IEC-6 intestinal epithelial cell monolayers, a dynamic release of this protein was observed with mAbIG3. Proteomic analysis identified the protein as a mature cathepsin B-like (gCatB) enzyme, whose proteolytic activity, detected in zymograms, was eliminated by CatB inhibitor E-64. This protein was named giardipain-1 due to its functional papain-like features and was purified by affinity chromatography using mAbIG3. Upon exposure to the purified, mature and secreted forms of giardipain-1, IEC-6 epithelial cell monolayers displayed membrane blebbing and phosphatidylserine exposure on the outer cell surface, indicating an apoptotic process. In Madin Darby Canine Kidney (MDCK) cell monolayers, giardipain-1 leads to the appearance of pore-like regions and of gaps along cell-cell junctions, to decreased transepithelial electrical resistance (TER), caspase-3 activation and poly-ADP-ribose polymerase (PARP) fragmentation. At early times during exposure, giardipain-1 co-localized at cell-cell junctions, associated with occludin and induced the delocalization and degradation of tight junction proteins occludin and claudin-1. The damage caused to epithelial monolayers by giardipain-1 was blocked by pre-incubation with the CatB B Inhibitor E-64. Furthermore, silencing the giardipain-1 gene in trophozoites lowered the proteolytic activity of giardipain-1 and reduced the damage in IEC-6 monolayers. The damage observed appears to be specific to giardipain activity since almost no damage was observed when IEC-6 monolayers were incubated with papain, a non-related cysteine protease. Hence this study suggests that giardipain-1 triggers, in epithelial cells, degradation of cell-cell junctional components and apoptotic damage, supporting the notion of giardiapain-1 as a virulence factor of Giardia. PMID- 29571982 TI - Anomalous coronary arteries arising from the opposite aortic sinus: When to intervene? PMID- 29571983 TI - Coronary artery abnormalities: Current clinical issues. AB - INTRODUCTION AND OBJECTIVE: Patients with anomalous coronary arteries arising from the opposite sinus of Valsalva (ACAOS), the left coronary artery (LCA) arising from the right sinus or the right coronary artery (RCA) from the left sinus with an interarterial course, may present from complete absence of symptoms to sudden cardiac death. Although there are guidelines on indications for surgery, controversy remains. METHODS: A retrospective review was performed of all adult patients diagnosed with ACAOS in our hospital between 2007 and 2016. Demographic, clinical, perioperative and follow-up data were collected from clinical records and summarized. A review of the published literature was performed with special emphasis on clinical presentation, surgical indications and results. RESULTS: Seven symptomatic patients underwent surgery (mean age 57.1+/-8.9 years, two male, five female); they recovered without complications and to date have had no recurrence of myocardial ischemia. One asymptomatic patient with an anomalous RCA has been medically followed without evidence of myocardial ischemia. A 75-year-old woman, diagnosed in 2008 with an anomalous LCA, was not referred for surgery and died suddenly six months after diagnosis. CONCLUSIONS: Surgery for coronary abnormalities is performed with low risk and all published series report full operative survival. The indications for surgery are well established for patients with interarterial anomalous LCA and symptomatic patients with interarterial anomalous RCA. However, there is some uncertainty concerning asymptomatic patients, particularly those with an anomalous interarterial RCA, for whom we propose a more assertive approach, if young or engaged in strenuous activities.

AB - OBJECTIVES: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are promising targeted therapies for EGFR-mutated non-small-cell lung cancer (NSCLC) patients. However, acquired resistance inevitably develops. Comprehensive and dynamic companion genomic diagnosis can gain insights into underlying resistance mechanisms, thereby help oncologists and patients to make informed decision on the potential benefit of the treatment. MATERIALS AND METHODS: A 67-year-old male who was initially diagnosed of EGFR L858R-mediated NSCLC received multiple lines of chemotherapy and EGFR TKI therapies after surgery. The EGFR mutational status of individual metastatic lesion was determined by genetic testing of the tumor tissue biopsies using next generation sequencing (NGS) throughout the patient's clinical course. An acquired potentially drug-resistant EGFR mutation was functionally validated in vitro and its sensitivity to different EGFR TKIs was assessed simultaneously. RESULTS: We have identified distinct resistance mechanisms to EGFR blockade in different metastatic lung lesions. Acquired EGFR T790M was first detected that leads to the resistance to the gefitinib treatment. Consequently, osimertinib was administrated and the response lasted until disease progressed. We identified a newly acquired EGFR L718V mutation in one lesion in conjunction with L858R, but not T790M, which showed stable disease on the following erlotinib treatment, while EGFR C797S together with L858R/T790M was detected in the other lesion that continuously progressed. In vitro functional studies demonstrated that EGFR L858R/L718V confers resistance to osimertinib, but retains sensitivity to the second generation TKI afatinib. CONCLUSION: We reported that distinct resistance mechanisms could arise in different metastases within the same patient in response to EGFR blockade. We also demonstrated in vitro that EGFR L718V mutation mediates resistance to osimertinib, but retains sensitivity to afatinib. We evidenced that dynamic companion genomic diagnosis offers valuable information to help define the mechanisms of drug resistance and to guide the selection of subsequent treatment. PMID- 29571987 TI - Clinical analysis by next-generation sequencing for NSCLC patients with MET amplification resistant to osimertinib. AB - INTRODUCTION: The efficacy of osimertinib was compromised by the development of resistance mechanisms, such as MET amplification. However, cohort studies of osimertinib resistance mechanism, and the correlation of MET and progression-free survival (PFS) after osimertinib resistance have been poorly investigated. OBJECTIVES: This study was carried out to study the acquired MET amplification after osimertinib resistance in advanced lung adenocarcinoma patients, and interrogate the correlation of clinical prognosis and MET amplification. METHODS: We performed capture-based sequencing on longitudinal plasma and tissue samples obtained before osimertinib treatment and after resistance development from lung adenocarcinoma patients to investigate the underlying resistance mechanism. We also investigated the correlation of MET amplification and patient prognosis after osimertinib resistance using Kaplan-Meier analysis. RESULTS: Paired biopsies before osimertinib treatment and after the resistance development revealed underlying resistance mechanisms. In addition, a cohort of 13 patients who developed disease progression after osimertinib resistance was investigated. Patients with MET amplification after osimertinib resistance commonly had inferior median progression-free survival (mPFS) than patients without MET amplification appearance or increase (3.5 months vs. 9.9 months, p = .117). Patients in MET amplification group also displayed poor median overall survival (mOS) compared to MET amplification negative group (15.6 months vs. 30.7 months, p = .885). Furthermore, combinatorial treatment of first/third-generation EGFR TKI and crizotinib was efficaciously administrated into two patients with newly acquired MET amplification after osimertinib resistance. Partial responses were achieved by them, both clinically and radiographically. CONCLUSIONS: We investigated the osimertinib resistance mechanism in a small cohort of lung adenocarcinoma patients, and demonstrated MET amplification was correlated with inferior PFS/OS after osimertinib treatment. Moreover, we reported the first clinical evidence of efficacy generated by combination of first-generation EGFR TKI icotinib and crizotinib after the resistance to osimertinib. PMID- 29571988 TI - MiR-192 and miR-662 enhance chemoresistance and invasiveness of squamous cell lung carcinoma. AB - OBJECTIVES: Overexpression of miR-192, miR-192* and miR-662 was previously found to correlate with poor prognosis of early-stage squamous cell lung cancer (SCC) patients. In this study, we investigated the relevance of these miRNAs to cancer cell biology and chemoresistance. MATERIALS AND METHODS: MiRNA expression profile was analysed in 10 non-small cell lung cancer (NSCLC) cell lines using RT-qPCR. H520 and H1703 cells were transfected with miRNA inhibitors (anti-miR-192, -192* and -662) for functional studies. Chemoresistance to cisplatin and etoposide was evaluated using MTT colorimetric assay. H520 cells were subjected to 3D soft-agar colony formation assay and H1703 cells to wound healing assay. Whole transcriptome analysis was used to assess the effect of miR-192 and miR-662 inhibition on gene expression. RESULTS: SCC cell lines, H520 and H1703, differed in miRNA expression and phenotypic features. MiR-192 and miR-662 inhibition decreased clonogenicity and motility of SCC cells. MiR-192 and miR-662 inhibition sensitized SCC cells to etoposide but not to cisplatin. Whole transcriptome analysis revealed genes regulated by miR-192 and miR-662 in SCC, relevant to maintaining chemoresistance, invasiveness, epithelial-mesenchymal transition (EMT) and immune evasion. CONCLUSIONS: We showed for the first time that miR-192 and miR-662 have functional role in SCC cells. Our findings suggest that targeting these miRNAs may impact both chemoresistance and invasiveness of SCC, and add to the evidence linking these aspects of tumour biology. Overexpression of miR-192 and miR-662 might be useful as a marker of resistance to etoposide. PMID- 29571989 TI - Neoadjuvant treatment followed by surgery versus definitive chemoradiation in stage IIIA-N2 non-small-cell lung cancer: A multi-institutional study by the oncologic group for the study of lung cancer (Spanish Radiation Oncology Society). AB - OBJECTIVES: The role of surgery in stage IIIA-N2 non-small cell lung cancer (NSCLC) is an actively debated in oncology. To evaluate the value of surgery in this patient population, we conducted a multi-institutional retrospective study comparing neoadjuvant chemoradiotherapy or chemotherapy plus surgery (CRTS) to definitive chemoradiotherapy (dCRT). MATERIAL AND METHODS: A total of 247 patients with potentially resectable stage T1-T3N2M0 NSCLC treated with either CRTS or dCRT between January 2005 and December 2014 at 15 hospitals in Spain were identified. A centralized review was performed to ensure resectability. A propensity score matched analysis was carried out to balance patient and tumor characteristics (n = 78 per group). RESULTS: Of the 247 patients, 118 were treated with CRTS and 129 with dCRT. In the CRTS group, 62 patients (52.5%) received neoadjuvant CRT and 56 (47.4%) neoadjuvant chemotherapy. Surgery consisted of either lobectomy (97 patients; 82.2%) or pneumonectomy (21 patients; 17.8%). In the matched samples, median overall survival (OS; 56 vs 29 months, log rank p = .002) and progression-free survival (PFS; 46 vs 15 months, log-rank p < 0.001) were significantly higher in the CRTS group. This survival advantage for CRTS was maintained in the subset comparison between the lobectomy subgroup versus dCRT (OS: 57 vs 29 months, p < 0.001; PFS: 46 vs 15 months, p < 0.001), but not in the comparison between the pneumonectomy subgroup and dCRT. CONCLUSION: The findings reported here indicate that neoadjuvant chemotherapy or chemoradiotherapy followed by surgery (preferably lobectomy) yields better OS and PFS than definitive chemoradiotherapy in patients with resectable stage IIIA-N2 NSCLC. PMID- 29571990 TI - Response to crizotinib in advanced ALK-rearranged non-small cell lung cancers with different ALK-fusion variants. AB - INTRODUCTION: Anaplastic lymphoma kinase (ALK) rearrangements are present in approximately 5% of non-small-cell lung cancers (NSCLCs). NSCLCs with ALK rearrangement can be effectively treated with crizotinib. However, magnitude and duration of responses are found to be heterogeneous. This study explored the clinical efficacy of crizotinib in different ALK variants. METHODS: Among 96 ALK rearrangement patients treated with crizotinib, 60 patients were identified with tumor specimens that could be evaluated by next-generation sequencing (NGS). We retrospectively evaluated the efficacy of crizotinib in different ALK variants. RESULTS: The median Progression-free survival (PFS) of the 96 ALK-rearrangement patients was 14.17 months. Among the 60 patients with NGS results, the most frequent variants were variant 3a/b (33.33%), variant 1 (23.33%) and variant 2 (15.00%). The percentage of rare EML4-ALK variants and non EML4-ALK variants were 10.00% and 18.33%. Survival analysis showed that patients with variant 2 appeared to have longer PFS than others (P = .021); also, patients with TP53 mutation seemed to have an unfavorable PFS than those with TP53 wild-type with a borderline p value (P = .068). After adjusting for other baseline characteristics, EML4-ALK variant 2 was identified as an important factor for a better PFS of crizotinib. We also found that patients with variant 3a/b had shorter duration of response to crizotinib; however, no significant difference of PFS was observed between the PFS of variant3a/b and non-v3 EML4-ALK variants. CONCLUSIONS: Our results indicate prolonged PFS in patients with EML4-ALK variant 2. PMID- 29571991 TI - High expression of P-cadherin is significantly associated with poor prognosis in patients with non-small-cell lung cancer. AB - OBJECTIVES: Placental (P)-cadherin expression is associated with malignant phenotype of cancer cell. The loss of E-cadherin has been thought to play a key role in tumor progression in several cancers. In this study, we aimed to clarify the role of P-cadherin expression in non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: NSCLC patients (n = 172) were enrolled in this study; among them, 107 harbored adenocarcinomas, and 65 had squamous cell carcinomas. We examined P-cadherin and E-cadherin expression by immunohistochemical analysis and assessed the associations between each cadherin expression and both cadherin expression patterns with clinicopathological factors and prognosis. To investigate the pathway to acquire tumor progression associated with P-cadherin and E-cadherin, we examined p120 catenin localization by immunohistochemical analysis. RESULTS: High P-cadherin expression was significantly associated with lymphatic metastasis, pathological stage, and Ki-67 proliferation index (P < .05, respectively). Low E-cadherin expression was significantly associated with maximum standardized uptake value, lymphatic metastasis, and pathological stage (P < .05, respectively). The cytoplasmic p120 catenin localization was associated with the low E-cadherin and high P-cadherin expression group (P < .001). High P cadherin expression was associated with shorter disease-free survival (P = .044) and shorter overall survival (OS; P = .044). The low E-cadherin and high P cadherin expression group was associated with shorter OS (P = .024). CONCLUSIONS: High P-cadherin expression was associated with tumor progression and poor patient survival in NSCLC. In these patients, the low E-cadherin expression might be associated with tumor progression involving cytoplasmic p120 catenin. PMID- 29571992 TI - The eighth TNM classification system for lung cancer: A consideration based on the degree of pleural invasion and involved neighboring structures. AB - OBJECTIVES: The eighth tumor-node-metastasis (TNM) classification system for lung cancer has been used since January 2017 and must be applied to an individual institution's database. METHODS: We analyzed pathological stage data of 2756 patients who underwent resection of non-small-cell lung cancer, particularly in terms of the degree of visceral pleural invasion and involved neighboring structures. RESULTS: Few patients had stage IIA disease (103, 4%); stratification between stages IB and IIA was insufficient (p = 0.129). When T2a tumors were divided into PL1 and PL2 subgroups based on the degree of pleural invasion, there was a significant prognostic difference between the subgroups (p < 0.001). By incorporating T2a tumors with PL2 (T2a-PL2) into the T2b category, modified stages IB, IIA (234, 8%), and IIB were well stratified (IB vs. IIA, p < 0.001; IIA vs. IIB, p = 0.011). Focusing on T3 tumors with PL3 (T3-PL3) invading neighboring structures, multivariate analysis for surveying pT3N0-2M0 tumors revealed that completeness of resection (p = 0.002), implementation of any postoperative therapies (p = 0.003), and subcategorization of whether only the pleura was infiltrated or other deeper structures were also invaded (p = 0.024) were significant and crucial predictors. N2 disease showed worse outcome than N0 1 diseases, with marginal difference (p = 0.054). CONCLUSION: T2a-PL2 tumors could be categorized into a worse prognostic T2b category. For T3-PL3 tumors involving resectable neighboring organs, subcategorization of whether there is only pleura infiltration (T3a) or other deeper structure invasion (T3b) could be a practical consideration. PMID- 29571993 TI - Is heterogeneity in stage 3 non-small cell lung cancer obscuring the potential benefits of dose-escalated concurrent chemo-radiotherapy in clinical trials? AB - The current standard of care for the management of inoperable stage 3 non-small cell lung cancer (NSCLC) is concurrent chemoradiotherapy (cCRT) using radiotherapy dose-fractionation and chemotherapy regimens that were established 3 decades ago. In an attempt to improve the chances of long-term control from cCRT, dose-escalation of the radiotherapy dose was assessed in the RTOG 0617 randomised control study comparing the standard 60 Gy in 30 fractions with a high-dose arm receiving 74 Gy in 37 fractions. Following the publication of this trial the thoracic oncology community were surprised to learn that there was worse survival in the dose-escalated arm and that for now the standard of care must remain with the lower dose. In this article we review the RTOG 0617 paper with subsequent analyses and studies to explore why the use of dose-escalated cCRT in stage 3 NSCLC has not shown the benefits that were expected. The overarching theme of this opinion piece is how heterogeneity between stage 3 NSCLC cases in terms of patient, tumour, and clinical factors may obscure the potential benefits of dose escalation by causing imbalances in the arms of studies such as RTOG 0617. We also examine recent advances in the staging, management, and technological delivery of radiotherapy in NSCLC and how these may be employed to optimise cCRT trials in the future and ensure that any potential benefits of dose-escalation can be detected. PMID- 29571994 TI - Eribulin inhibits the growth of small cell lung cancer cell lines alone and with radiotherapy. AB - OBJECTIVES: Small cell lung cancer (SCLC) patients of all stages are treated with etoposide and cisplatin or carboplatin with or without surgery or chest radiotherapy. Initial response rates are >=70% however the majority of patients relapse and are resistant to additional therapies due to pan-resistance to these salvage therapies. Therefore, new treatments are urgently needed. The non-taxane microtubule inhibitor eribulin has produced responses in heavily pretreated breast cancer patients. We evaluated the efficacy of eribulin alone and in combination with radiation in a panel of SCLC cell lines established from patients prior to or after receiving chemotherapy and or radiation. MATERIAL AND METHODS: Growth inhibition by eribulin alone, radiation alone and the combination was assessed by MTS assay and clonogenic survival. Eribulin induced cell cycle arrest was evaluated by FACS. Apoptosis was evaluated by using the Caspase-GLO 3/7 luminescent plate assay and by the Vybrant apoptosis assay with analysis by FACS. RESULTS: Eribulin mesylate inhibited the growth of all 17-SCLC lines at concentrations of <=10 nM which is a clinically achievable dose. Growth inhibition was not significantly different between cell lines established prior to or after chemotherapy (p = .5). Concurrent eribulin + radiation induced a greater G2-M arrest, an increase in apoptotic cells and increased growth inhibition over radiation alone. CONCLUSIONS: Eribulin was highly active alone and in combination with radiation in treatment naive SCLC lines and lines established from previously treated patients. In vivo pre-clinical studies of eribulin alone and in combination with radiation should be considered in SCLC cell lines. PMID- 29571995 TI - Pre-operative quantification of pulmonary function using hybrid-SPECT/low-dose CT: A pilot study. AB - RATIONALE: Pre-operative lobar function is estimated by scintigraphy in patients with pulmonary malignancies and compromised function. This study compared the lobar perfusion determined by scintigraphy (PS) with data from SPECT/low-dose-CT (SPECT/ldCT) analyzed manually and semi-automatic. METHODS: Retrospective analysis on 39 patients (m/f = 25/14; age: 72.5 [22-89] years) with indication for pulmonary perfusion scintigraphy. Imaging was performed using SPECT/ldCT. Data was analyzed manually and by semi-automatic software. Readers' confidence in 3D-segmentation was scored by two independent readers. Interrater agreement was calculated. In addition, Spearman's rank correlation and Wilcoxon's test were used. RESULTS: Results from PS differed significantly from SPECT/ldCT processed manually or semi-automatically in 4/5 lobes (total difference <=21.6%; rho >=0.44) and in 3/5 (total difference 21.6%; rho >=0.37), respectively. Readers' confidence in 3D-segmentation showed a perfect interrater agreement (kappa = 0.98). CONCLUSION: Quantification of lobar perfusion by SPECT/ldCT differs significantly from planar scintigraphy (e.g., with potential influence on therapy). The semi-automatic software analysis provides an applicable methodology. PMID- 29571996 TI - Optimal surgical approach to thymic malignancies: New trends challenging old dogmas. AB - Until recently, the surgical approach to thymic tumors has remained basically unchanged. The collaborative effort led by ITMIG with the collaboration of regional and society-based interest groups (ESTS, JART) produced an enthusiastic surge of interest in testing the new technological advances in thoracic surgery and many historical dogmas in thymic surgery have been questioned and challenged. The present review addresses the new trends in the optimal surgical management of thymic tumors based on the review of the current literature. 1. Minimally invasive techniques (MIT) including video-assisted thoracic surgery (VATS) and robotic-assisted thoracic Surgery (RATS) are now to be considered the standard of care in early-stage thymic tumors. MIT are no inferior to open approaches in terms of postoperative complications, loco-regional recurrence rates and survival. MIT are associated with a shorter length of stay, reduced intraoperative blood loss and better cosmetic results. 2. The adoption of the ITMIG/IASLC TNM staging system for thymic tumors requires a paradigm shift among thoracic surgeons to include regional lymphadenectomy according to the IASLC/ITMIG nodal map in the surgical management of thymic tumors. 3. A limited thymectomy instead of total thymectomy along with the removal of the thymic tumor in nonmyasthenic Stage I-II tumors has been proposed by some authors, although the results are not uniform. Until more mature data is available, adherence to the current guidelines recommending total thymectomy in addition to thymomectomy is always indicated. 4. In locally-advanced Stage IVa patients with pleural involvement, major pleural resections, including pleurectomy/decortication or extrapleural pneumonectomy are indicated, provided a complete resection of the pleural deposits is anticipated, usually in a multidisciplinary setting, with excellent long-term results. The incorporation of these new concepts and techniques in the surgical armamentarium of the thoracic surgeons dealing with thymic malignancies will certainly be of help in the optimal management of these patients. PMID- 29571997 TI - Histology significantly affects recurrence and survival following SBRT for early stage non-small cell lung cancer. AB - BACKGROUND: Contrary to prevailing notions of uniform efficacy regarding stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer (NSCLC), a recent report has indicated increased risk of local failure for squamous cell carcinoma (SCC). As those data have not been corroborated by other studies, we performed a multi-institutional analysis to evaluate the influence of histology on post-SBRT outcomes. MATERIALS AND METHODS: Records from 152 consecutive patients who received SBRT for primary early-stage NSCLC at two academic medical centers were retrospectively assessed. Primary comparison was between SCC and adenocarcinoma. Patient outcomes including actuarial recurrences and overall survival were calculated using the Kaplan-Meier method. Univariable and multivariable logistic regression analyses addressed associated factors. RESULTS: At a median follow-up of 44 months, patients with SCC had an increased risk of local, (hazard ratio (HR) (95% confidence interval (CI)): 1.69 (1.05 2.73), p = 0.032), regional (HR (95% CI): 2.03 (1.24-3.33), p = 0.005), and distant failure (HR (95% CI): 1.71 (1.06-2.77), p = 0.036). Median times to local (32 m vs 50m, p = 0.023), regional (26 m vs 50 m, p = 0.011), and distant (26 m vs 50 m, p = 0.024) failure were all significantly reduced in SCC histology. SCC histology was also independently associated with an increased risk for death (HR: 1.80 (1.10-2.94), p = 0.019) and had a 5-yr overall survival of 26%, versus 41% for adenocarcinoma (p = 0.016). CONCLUSIONS: This multi-institutional analysis corroborates that SCC histology is independently predictive for local, regional, and distant recurrence and worse overall survival. Future data are needed to determine if treatment paradigms should differ by histology for early stage NSCLC. PMID- 29571998 TI - Identification of a novel KIF13A-RET fusion in lung adenocarcinoma by next generation sequencing. AB - OBJECTIVES: RET fusions have been reported in 1-2% of lung adenocarcinomas, and represent an actionable target. Patients whose tumors possess RET fusion are associated with clinical benefit from the treatment with multi-kinase inhibitors such as cabozantinib and vandetanib. Further molecular screening for RET fusions is warranted. Novel KIF13A-RET fusion containing an intact RET kinase domain involving exons 1-18 of KIF13A and exons 12-20 of RET was identified in a lung cancer specimen from an 74-year-old Asian never smoker by next-generation sequencing (NGS) during clinical care. The patient was negative for EGFR, ALK, ROS1 and other putative driver alterations. Fusion analysis is consistent with other described RET fusions and is predicted to result in aberrant constitutive activation caused by dimerization and sensitivity to RET-directed therapies. We describe a novel RET-fusion with molecular characteristics consistent with RET driven non-small cell lung cancer. Our case expands the spectrum of RET fusion partners and supports broad molecular profiling in non-small cell lung cancer optimizing patient therapeutic options. The new RET fusion has immediate clinical implications for cancer patients. PMID- 29571999 TI - The ratio of cancer cells to stroma within the invasive area is a histologic prognostic parameter of lung adenocarcinoma. AB - OBJECTIVES: This study evaluated whether the proportion of cancer cells to non cancerous stroma within the invasive area is associated with the prognosis of patients with lung adenocarcinoma. MATERIALS AND METHODS: A total of 127 patients with lung adenocarcinomas with tumors larger than 3 cm in total size were enrolled in this study. We classified the tumors according to the ratio of area occupied by cancer cells within the invasive area (Type A: more than 50% of the invasive area, Type B: 10-50%, and Type C: less than 10%) and analyzed the clinicopathological differences between Types A, B, and C. RESULTS: The invasive size of Type A tumors (n = 35) was significantly larger than those of the other two tumor types; however, there was no significant difference in the invasive size between Types B (n = 65) and C (n = 25) tumors. The recurrence-free survival time of patients with Type C tumors was significantly longer than those of patients with Type A and B (P < .001) tumors. Multivariate analysis revealed that Type C tumor was an independent favorable prognostic factor (P = .037) but that invasive size was not. The invasive area of Type C tumor was composed of a significantly higher proportion of collapsed elastic fibers than the invasive areas of Type A and B tumors (P < .001). CONCLUSION: A lower cancer cell to stroma ratio within the invasive area could be a significant prognostic factor in lung adenocarcinoma, suggesting that not only the invasive size but also the invasive character might be an important histologic prognostic parameter. PMID- 29572000 TI - PD-L1 expression in lung adenocarcinoma harboring EGFR mutations or ALK rearrangements. AB - OBJECTIVES: Expression of programmed cell death-ligand 1 (PD-L1) has been associated with clinical outcome of programmed cell death-1 (PD-1) pathway blockade in non-small cell lung cancer (NSCLC). The PD-L1 IHC 22C3 pharmDx assay, the only companion diagnostic for pembrolizumab therapy, has revealed that ~30% of all NSCLCs express PD-L1 at a high level. The frequency of high PD-L1 expression in NSCLCs with known driver oncogenes has remained unclear, however. MATERIALS AND METHODS: We retrospectively evaluated PD-L1 expression with the 22C3 assay in tumor tissue of 80 lung adenocarcinoma patients including 71 with EGFR mutations and 9 with ALK rearrangements, all of whom were treated with corresponding tyrosine kinase inhibitors (TKIs). RESULTS: Of the 80 tumors analyzed, 26 (32.5%) had a PD-L1 tumor proportion score (TPS) of 1%-49% and 9 (11.3%) had a PD-L1 TPS of >=50%; 35 (43.8%) thus had a PD-L1 TPS of >=1%. Of the 71 tumors with EGFR mutations, 23 (32.4%) had a PD-L1 TPS of 1%-49% and 7 (9.9%) had a PD-L1 TPS of >=50%. A PD-L1 TPS of >=1% was not associated with any clinical characteristic examined. Progression-free survival on initial TKI treatment was significantly poorer for patients with a PD-L1 TPS of >=1% than for those with a PD-L1 TPS of <1% (p = .016). CONCLUSIONS: A subset of patients with EGFR mutations or ALK rearrangements had a PD-L1 TPS of >=50%. Prospective studies are thus warranted to examine the efficacy of PD-1/PD-L1 inhibitors in such patients. PMID- 29572001 TI - Prognostic significance of 18F-fluorodeoxyglucose uptake of bone marrow measured on positron emission tomography in patients with small cell lung cancer. AB - OBJECTIVES: We investigated whether 18F-fluorodeoxyglucse (FDG) uptake of bone marrow (BM) on positron emission tomography/computed tomography (PET/CT) has implications for predicting clinical outcomes in patients with small cell lung cancer (SCLC). METHODS: We retrospectively enrolled 70 SCLC patients who underwent FDG PET/CT prior to treatment. On PET/CT, maximum FDG uptake of all tumor lesions (Tmax), coefficient of variation (COV) of FDG uptake of primary tumor, and mean FDG uptake of BM (BM SUV) were measured. The relationships of BM SUV with PET/CT parameters of SCLC and serum markers were evaluated. Univariate and multivariate analyses were performed to assess the significance of BM SUV for predicting progression-free survival (PFS) and overall survival (OS). RESULTS: BM SUV had significant positive correlations with Tmax, COV of primary tumor, white blood cell count, and serum C-reactive protein level (p < .05). On univariate analysis, BM SUV showed significant association with only PFS (p = .006). On multivariate analysis, Veterans Administration Lung Cancer Study Group (VALSG) stage, N stage, M stage, Tmax, and BM SUV were independent prognostic factors for PFS (p < .05) and, for OS, VALSG stage and M stage were independent prognostic factors (p < .05). Among patients with limited disease, patients with high FDG uptake of BM had significantly worse PFS than did those with low FDG uptake of BM (p < .05), but, there was no significant difference in PFS between patients with extensive disease and patients with limited disease and high FDG uptake of BM (p > .05). CONCLUSION: FDG uptake of BM was an independent predictor of disease progression in SCLC patients. Patients with limited disease and high FDG uptake of BM had similar PFS to those with extensive disease. PMID- 29572003 TI - Clinicopathological characteristics of POLE mutation in patients with non-small cell lung cancer. AB - BACKGROUND: Mutations in polymerase epsilon (POLE), a DNA polymerase involved in DNA replication and repair, have been investigated in endometrial cancers and response to programmed cell death protein 1 (PD-1)/PD-1 ligand (PD-L1) immunotherapy. However, the frequency of POLE gene mutation in patients with non small cell lung cancer (NSCLC) has not been reported. MATERIALS AND METHODS: We assessed POLE mutation in 319 patients with NSCLC by next-generation sequencing (NGS) of 416 cancer-associated genes. Expression of PD-L1, DNA mismatch repair proteins (MMR), and the abundance of CD8-positive tumor infiltrating lymphocytes (TILs) were assayed by immunohistochemistry. Progression-free survival (PFS) was evaluated using the Kaplan-Meier method and compared among groups using log-rank tests. RESULTS: Nine of the 319 patients (2.8%) harbored POLE mutation. All nine had adenocarcinomas. The median tumor mutational burdens (TMBs) were 12.2/Mb and 7.8/Mb in patients with and without POLE mutation, respectively (P = 0.026). PD L1, MMR (including MSH2, MSH6, MLH1 and PMS2), and CD8-positive TILs were evaluated in all nine patients. No microsatellite instability was detected, but seven patients had high levels of CD8-positive TILs and five demonstrated PD-L1 staining >25%. One patient receiving the PD-L1 antibody atezolizumab demonstrated a partial response, with a PFS of >8 months. CONCLUSION: POLE mutation represents an uncommon phenotype in NSCLC. TMB, PD-L1 expression, and CD8-positive TILs were all higher in patients with mutant compared with wild-type POLE. POLE mutation may thus represent a candidate biomarker for response to immunotherapy in patients with NSCLC. PMID- 29572002 TI - Early Contrast Enhancement: A novel magnetic resonance imaging biomarker of pleural malignancy. AB - INTRODUCTION: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and applicable to minimal pleural thickening. MATERIALS AND METHODS: 60 consecutive patients with suspected PM underwent contrast-enhanced 3-T MRI then pleural biopsy. In 58/60, parietal pleura signal intensity (SI) was measured in multiple regions of interest (ROI) at multiple time-points, generating ROI SI/time curves and Mean SI gradient (MSIG: SI increment/time). The diagnostic performance of Early Contrast Enhancement (ECE; which was defined as a SI peak in at least one ROI at or before 4.5 min) was compared with subjective MRI and Computed Tomography (CT) morphology results. MSIG was correlated against tumour MVD (based on Factor VIII immunostain) in 31 patients with Mesothelioma. RESULTS: 71% (41/58) patients had PM. Pleural thickening was <10 mm in 49/58 (84%). ECE sensitivity was 83% (95% CI 61-94%), specificity 83% (95% CI 68-91%), positive predictive value 68% (95% CI 47-84%), negative predictive value 92% (78-97%). ECE performance was similar or superior to subjective CT and MRI. MSIG correlated with MVD (r = 0.4258, p = .02). DISCUSSION: ECE is a semi-objective, perfusion based biomarker of PM, measurable in minimal pleural thickening. Further studies are warranted. PMID- 29572004 TI - Phase II trial of preoperative pemetrexed plus carboplatin in patients with stage IB-III nonsquamous non-small cell lung cancer (NSCLC). AB - OBJECTIVES: The combination of pemetrexed and carboplatin is a standard first line treatment for patients with advanced NSCLC. In this pilot phase II trial, we evaluated the feasibility of using pemetrexed and carboplatin as neoadjuvant therapy, prior to definitive surgical resection, for patients with localized NSCLC. PATIENTS AND METHODS: Patients with potentially resectable, previously untreated, clinical stage IB-III, nonsquamous NSCLC were eligible for this trial. All patients received 4 cycles of pemetrexed (500 mg/m2) and carboplatin (AUC 6.0) administered at 21 day intervals. Three to 6 weeks after completion of chemotherapy, definitive surgical resection was attempted. The primary endpoint of this trial was the 3-year survival rate. RESULTS: Forty-six patients began protocol treatment, and 40 completed 4 courses of pemetrexed/carboplatin. Surgical resection was performed in 27 patients (59%); all had pathologic partial responses. The estimated 3-year survival rate for the entire group was 46%. Toxicity of neoadjuvant therapy was consistent with toxicity previously reported with pemetrexed/carboplatin. CONCLUSIONS: Administration of 4 courses of pemetrexed/carboplatin was feasible. The efficacy was similar to neoadjuvant regimens previously investigated. A significant number of patients 19 of 46 (41%) in this trial did not have surgical resection after neoadjuvant therapy. Further investigation of the role of neoadjuvant pemetrexed/carboplatin requires a larger, randomized clinical trial. PMID- 29572005 TI - Programmed cell death-ligand 1 (PD-L1) expression is associated with RAS/TP53 mutations in lung adenocarcinoma. AB - INTRODUCTION: The systematic assessment of anti-programmed cell death ligand 1 (PD-L1) expression by immunohistochemistry (IHC) in lung adenocarcinomas is becoming standard practice. However, the assessment of PD-L1 expression on small tissue specimens needs to be evaluated and the association with other features more thoroughly analyzed. METHODS: This retrospective single center study evaluated the immunohistochemical expression of the SP263 anti-PD-L1 antibody on tissue microarrays (TMA) of 152 surgically resected lung adenocarcinomas, using a 25% positivity threshold. The positive cases and 50 randomly chosen negative cases in tissue microarray (TMA) were reassessed on whole tissue sections. The results were correlated to clinical, histopathological and to molecular data obtained through the screening of 214 mutations in 26 genes (LungCarta panel, Agena Biosciences). RESULTS: Among 152 primary lung adenocarcinomas, 19 cases (13%) showed PD-L1 expression. The agreement between TMA and whole tissue sections was 89%, specificity was 97%. PD-L1 expression was correlated to RAS mutations (p = .04), RAS/TP53 co-mutations (p = .01) and to the solid or acinar subtype (p = .048). CONCLUSIONS: With the SP263 PD-L1 antibody, small samples appear as a reliable means to evaluate the PD-L1 status in lung adenocarcinoma. The association between PD-L1 expression and RAS/TP53 mutations may have clinical relevance to predict the efficacy of PD-1/PD-L1 immune checkpoints inhibitors. PMID- 29572006 TI - Challenges and future direction of molecular research in air pollution-related lung cancers. AB - Hazardous air pollutants or chemical release into the environment by a variety of natural and/or anthropogenic activities may give adverse effects to human health. Air pollutants such as sulphur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), heavy metals and particulate matter (PM) affect number of different human organs, especially the respiratory system. The International Agency for Research on Cancer (IARC) reported that ambient air pollution is a cause of lung cancer. Recently, the agency has classified outdoor air pollution as well as PM air pollution as Group 1 carcinogens. In addition, several epidemiological studies have shown a positive association between air pollutants to lung cancer risks and mortality. However, there are only a few studies examining the molecular effects of air pollution exposure specifically in lung cancer due to multiple challenges to mimic air pollution exposure in basic experimentation. Another major issue is the lack of adequate adjustments for exposure misclassification as air pollution may differ temporo-spatially and socioeconomically. Thus, the purpose of this paper is to review the current molecular understanding of air pollution-related lung cancer and potential future direction in this challenging yet important research field. PMID- 29572007 TI - PD-L1 expression in large cell neuroendocrine carcinoma of the lung. AB - OBJECTIVES: Large cell neuroendocrine carcinoma of the lung (LCNEC) is associated with an unfavorable prognosis and only few patients are eligible for surgery. In most patients, chemotherapy is recommended alone or in addition to resection. Novel immunotherapies blocking the PD-L1 pathway have been introduced into therapeutic regimens for NSCLC with great success. In order to evaluate a possible efficacy of an anti-PD-L1 therapy, we analyzed the frequency of PD-L1 expression in LCNEC. MATERIAL AND METHODS: We retrospectively reviewed data from 76 patients with LCNEC treated in our institution between 1998 and 2010. The expression of PD-L1 was examined on the tumor cells and the tumor surrounding tissue by immunohistochemistry. An expression of >1% was considered as positive. Statistical analysis was performed to determine significant predictors for survival. RESULTS: 56 of 76 patients with LCNEC were treated with a potentially therapeutic surgical approach. Tumor-specific survival (TSS) of the entire cohort was 29% at five years. 17 patients (22.3%) had PD-L1 positive tumors and 12 of these had no additional PD-L1 expression in the adjacent immune cell infiltrate. Tumor-flanking immune cells were found PD-L1 positive 28 patients; 16 of these had no additional expression on the tumor cells. The most considerable difference in survival was found when comparing patients with isolated PD-L1 expression on tumor cells and PD-L1 negative immune cell infiltrate to their counterpart (positive immune-cell infiltrate and PD-L1 negative tumor cell surface; 5-year TSS: 0% vs. 60%; p < 0.017). CONCLUSION: PD-L1 expression in LCNEC was associated with poorer survival whereas PD-L1 expression in the tumor microenvironment seemed to have a beneficial effect. Therapeutic approaches have to be evaluated in future. PMID- 29572008 TI - What CT characteristics of lepidic predominant pattern lung adenocarcinomas correlate with invasiveness on pathology? AB - OBJECTIVES: The International Association for the Study of Lung Cancer, American Thoracic Society and European Respiratory Society lung adenocarcinoma classification in 2011 defined three lepidic predominant patterns including adenocarcinoma in situ, minimally invasive adenocarcinoma and lepidic predominant adenocarcinoma. We sought to correlate the radiology and pathology findings and identify any computed tomography (CT) features which can be associated with invasive growth. MATERIALS AND METHODS: An institutional review board approved, retrospective study was conducted evaluating 63 patients with resected, pathologically confirmed, adenocarcinomas with predominant lepidic patterns. Preoperative CT images of the nodules were assessed using quantitative and qualitative radiographic descriptors while blinded to pathologic sub classification and size. Maximum diameter was measured after evaluation of the axial, sagittal and coronal planes. Radiologic - pathologic associations were examined using Fisher's exact test, the Kruskal-Wallis test and the Spearman correlation coefficient (rho). RESULTS AND CONCLUSION: Increasing maximum diameter of the whole lesion (ground glass and solid component) on CT was significantly associated with invasiveness (p = .003), as was the maximum pathologic specimen diameter (p = .008). Larger diameter of the solid component on CT was also found in lepidic predominant adenocarcinoma compared to minimally invasive adenocarcinoma (median 10.5 vs 2 mm, p = .005). More invasive tumors had higher visual estimated percentage solid component compared to whole lesion measurement on CT (p = .014). CT and pathologic measurements were positively correlated, although only moderately (rho = .66) for the maximum whole lesion size and fair (rho = .49) for solid/invasive component maximum measurements. Larger whole lesion size and solid component size of lepidic predominant pattern adenocarcinomas are associated with lesion invasiveness, although radiologic and pathologic lesion measurements are only fair-moderately positively correlated. PMID- 29572009 TI - Combined effect of ERCC1 and ERCC2 polymorphisms on overall survival in non squamous non-small-cell lung cancer patients treated with first-line pemetrexed/platinum. AB - OBJECTIVES: Polymorphisms of DNA repair genes may affect DNA repair capacity and the sensitivity of platinum doublets chemotherapy in non-small-cell lung cancer (NSCLC). We prospectively evaluated whether single nucleotide polymorphisms (SNPs) of ERCC1, ERCC2, XRCC1, and XRCC3 were associated with treatment outcome in advanced non-squamous NSCLC patients receiving pemetrexed/platinum as their first-line chemotherapy. MATERIALS AND METHODS: Genotyping of six SNPs in four DNA repair genes in 58 patients treated with first-line pemetrexed/platinum was performed using TaqMan SNP Genotyping Assays. RESULTS: The wild-type ERCC1 8092 (C/C) was significantly associated with a better objective response compared to the variant genotypes (C/A + A/A) (48% vs 10%, P = .005). In the multivariate Cox proportional hazards model, we found that individuals with a wild-type genotype of ERCC1 Asn118Asn, ERCC1 C8092A and ERCC2 Asp312Asn had significantly better overall survival (OS) than those with a heterozygous or homozygous variant genotype. On the other hand, the heterozygous variant genotype of ERCC2 Lys751Gln was associated with better OS than that of the wild-type genotype. We further explored the combined effect of SNPs on OS, and found a significant allele/dose dependent trend toward decreasing OS in patients with an increasing number of unfavorable alleles among four SNPs in ERCC1 and ERCC2. The median OS of patients with two or three unfavorable alleles (30.1 and 30.5 months, respectively) was significantly longer than that of patients with 4 unfavorable alleles (11.8 months, log-rank test for trend, P = .001). CONCLUSION: A combination of ERCC1 and ERCC2 polymorphisms may predict OS among pemetrexed/platinum treated advanced non-squamous NSCLC patients. PMID- 29572010 TI - Heterotopic production of ceruloplasmin by lung adenocarcinoma is significantly correlated with prognosis. AB - OBJECTIVES: Ceruloplasmin (CP) is a well-known copper binding protein synthesized mainly in the liver, but its expression is known to be elevated in the serum of cancer patients and in malignant tumor cells. Lung cancer is the leading cause of cancer-related death worldwide, and adenocarcinoma is the main histological type of lung cancer. However, the role of CP in lung adenocarcinoma is still unclear. Here we examined and compared the expression of CP in various histological subtypes of lung adenocarcinoma and its correlation with clinicopathological parameters. MATERIALS AND METHODS: We examined CP expression in lung adenocarcinoma samples and cell lines using quantitative real-time RT-PCR and Western blot analysis. Immunohistochemistry for CP was carried out using 196 specimens of lung adenocarcinoma. RESULTS: CP expression was significantly higher in invasive adenocarcinoma than in adenocarcinoma in situ (AIS), and was significantly correlated with poorer outcome, pathological stage, pT, and pN. Multivariate analysis showed that CP expression was an independent prognostic factor for lung adenocarcinoma patients. Furthermore, Western blot analysis using protein extracted from lung adenocarcinoma cell lines revealed the secreted form of CP. CONCLUSION: CP is produced heterotopically in lung adenocarcinoma cells and its expression is associated with tumor progression. In view of the presence of the secreted form of CP in tumor cells, CP may be a useful biomarker for lung adenocarcinoma. PMID- 29572012 TI - Effects of paeoniflorin on neurobehavior, oxidative stress, brain insulin signaling, and synaptic alterations in intracerebroventricular streptozotocin induced cognitive impairment in mice. AB - Paeoniflorin (PF) is a natural monoterpene glycoside in Paeonia lactiflora pall with anti-diabetic, antioxidant, anti-inflammatory, and neuro-protective properties. This study was designed to investigate the neuroprotective effects of PF against cognitive deficits induced by intracerebroventricular (ICV) injection of streptozotocin (STZ) in mice. STZ was injected twice intracerebroventrically (3 mg/kg ICV) on alternate days (day 1 and day 3) in mice. Daily treatment with PF (10 mg/kg per day, intraperitoneally) starting from the first dose of STZ for 21 days showed an improvement in ICV-STZ induced cognitive deficits as assessed by novel object recognition and Morris water maze (MWM) test. PF significantly attenuated STZ induced mitochondrial dysfunction manifested by dramatically elevated cytochrome c oxidase activity and ATP synthesis, and restoration of the mitochondrial membrane potential (MMP), and oxidative stress in hippocampus and in the cortex compared to control. Moreover, PF treatment also markedly increased synaptic density in the CA1 region of the hippocampus compared to control. Furthermore, PF ameliorated defective insulin signaling by up-regulating p-PI3K and p-Akt protein expression while downregulating p-IRS-1 protein expression. Taken together, the outcomes of the current study suggest the therapeutic potential of PF in the cognitive deficits induced by ICV-STZ. PMID- 29572011 TI - Analysis of circulating tumor DNA in breast cancer as a diagnostic and prognostic biomarker. AB - Despite all the advances in diagnosis and treatment of breast cancer, a large number of patients suffer from late diagnosis or recurrence of their disease. Current available imaging modalities do not reveal micrometastasis and tumor biopsy is an invasive method to detect early stage or recurrent cancer, signifying the need for an inexpensive, non-invasive diagnostic modality. Cell free tumor DNA (ctDNA) has been tried for early detection and targeted therapy of breast cancer, but its diagnostic and prognostic utility is still under investigation. This review summarizes the existing evidence on the use of ctDNA specifically in breast cancer, including detection methods, diagnostic accuracy, role in genetics and epigenetics evaluation of the tumor, and comparison with other biomarkers. Current evidence suggests that increasing levels of ctDNA in breast cancer can be of significant diagnostic value for early detection of breast cancer although the sensitivity and specificity of the methods is still suboptimal. Additionally, ctDNA allows for characterizing the tumor in a non invasive way and monitor the response to therapy, although discordance of ctDNA results with direct biopsy (i.e. due to tumor heterogeneity) is still considered a notable limitation.

AB - INTRODUCTION: The power output of e-cigarettes varies considerably, as does the composition of liquids used with these products. Most e-cigarette liquids contain two primary solvents: propylene glycol (PG) and vegetable glycerin (VG). The primary aim of this study was to examine the extent to which PG and VG composition and device power interact with each other to influence e-cigarette nicotine emissions. METHODS: Aerosols were generated using a 2nd generation e cigarette and an automatic smoking machine. Nicotine was measured in aerosols, via gas chromatography, produced from three solutions containing pure PG, pure VG, or a mixture of both solvents (50:50) across three different power settings (4.3, 6.7, and 9.6 W). RESULTS: At the lowest power setting, nicotine yield increased significantly as more PG was added to the solution. However, as device power was increased, differences in nicotine yield across liquids became less pronounced. At the highest power setting (9.6 W), nicotine yields did not differ across the three liquids examined. CONCLUSIONS: The present study demonstrated that the extent to which e-cigarette liquid PG and VG composition influences nicotine emissions is dependent on device power. Thus, device power may influence e-cigarette nicotine emissions to a greater degree relative to solvent concentrations. PMID- 29572014 TI - Anticonvulsants lamotrigine and riluzole disrupt maternal behavior in postpartum female rats. AB - Maternal behavior is a highly motivated and well-organized social behavior. Previous studies have reported that anticonvulsants are frequently used in postpartum bipolar disorder. However, the maternal disruptive effect of the anticonvulsants has not been explored. The purpose of the present study was to examine the effect of anticonvulsants lamotrigine and riluzole on maternal behavior in postpartum female rats. On postpartum Day 3, Sprague-Dawley mother rats were given a single intraperitoneal injection of vehicle, lamotrigine (15, 25, 35 mg/kg), or riluzole (2, 4, 8 mg/kg). Maternal behavior was tested 30 min before and after injection. Animals treated with lamotrigine or riluzole had a longer pup retrieval latency, retrieved fewer pups into the nest, spent less time on nursing pups, as well as on building the disturbed nest, and animals treated with riluzole spent less time on pup licking. Whereas, the drugs in the tested doses did not shorten the total duration of behavior unrelated to maternal behavior. Overall, these data indicate that lamotrigine and riluzole disrupt major components of maternal behavior in postpartum female rats, but do not inhibit the behaviors unrelated to maternal behavior, which indicates that the maternal disruptive effect is not due to nonspecific sedative effect. PMID- 29572015 TI - Differential effects of single versus repeated minocycline administration-Lack of significant interaction with chronic alcohol history. AB - Neuroimmune cytokines are increased with alcohol withdrawal and may mediate clinical responses associated with alcoholism. Because minocycline regulates the level of cytokines, it has been suggested as a therapeutic for disorders associated with alcohol. Male Wistar rats were exposed to chronic intermittent alcohol (CIA) comprising three 5-day cycles of ethanol liquid diet separated by 2 days of withdrawal. Rats were tested on social interaction, a measure of anxiety like behavior, followed immediately by collection of amygdala tissue to measure CCL2 and TNFalpha or collection of the blood to measure corticosterone (CORT). One group received a single minocycline injection 3 h into the final CIA withdrawal and was tested 2 h later. A second group received injections during each of the three withdrawals and was similarly tested during the final acute withdrawal. A third group received a single injection at 23 h into withdrawal (extended withdrawal) and was tested 6 h later. Results showed that CIA withdrawal increased anxiety-like behavior. A single injection of minocycline during the final acute withdrawal increased anxiety-like behavior in rats that consumed liquid diet with or without alcohol, but this effect disappeared with repeated injections of minocycline. Differences in alcohol intake, blood alcohol level, and plasma CORT levels did not explain results. Only repeated injections of minocycline decreased TNFalpha mRNA levels in rats that consumed liquid diet with or without alcohol. When a single injection of minocycline was given during extended withdrawal, it decreased CCL2 mRNA levels, but did not reverse the elevation of CCL2 protein. These results suggest that minocycline has actions in brain and on behavior, but minocycline does not significantly impact these actions in relation to alcohol withdrawal. PMID- 29572016 TI - Outcomes of Radiofrequency Ablation Therapy for Large Benign Thyroid Nodules: A Mayo Clinic Case Series. AB - OBJECTIVE: To assess the effectiveness, tolerability, and complications of radiofrequency ablation (RFA) in patients with benign large thyroid nodules (TNs). PATIENTS AND METHODS: This is a retrospective review of 14 patients with predominantly solid TNs treated with RFA at Mayo Clinic in Rochester, Minnesota, from December 1, 2013, through October 30, 2016. All the patients declined surgery or were poor surgical candidates. The TNs were benign on fine-needle aspiration, enlarging or causing compressive symptoms, and 3 cm or larger in largest diameter. We evaluated TN volume, compressive symptoms, cosmetic concerns, and thyroid function. RESULTS: Median TN volume reduction induced by RFA was 44.6% (interquartile range [IQR], 42.1%-59.3%), from 24.2 mL (IQR, 17.7 42.5 mL) to 14.4 mL (IQR, 7.1-19.2 mL) (P<.001). Median follow-up was 8.6 months (IQR, 3.9-13.9 months). Maximum results were achieved by 6 months. Radiofrequency ablation did not affect thyroid function. In 1 patient with subclinical hyperthyroidism due to toxic adenoma, thyroid function normalized 4 months after ablation of the toxic nodule. Compressive symptoms resolved in 8 of 12 patients (67%) and improved in the other 4 (33%). Cosmetic concerns improved in all 8 patients. The procedure had no sustained complications. CONCLUSION: In this population, RFA of benign large TNs performed similarly to the reports from Europe and Asia. It induces a substantial volume reduction of predominantly solid TNs, improves compressive symptoms and cosmetic concerns, and does not affect normal thyroid function. Radiofrequency ablation has an acceptable safety profile and should be considered as a low-risk alternative to conventional treatment of symptomatic benign TNs. PMID- 29572017 TI - The view of experts on initiatives to be undertaken to promote equity in the access to orphan drugs and specialised care for rare diseases in Spain: A Delphi consensus. AB - OBJECTIVES: To reach a consensus amongst experts on the most feasible actions to be undertaken to facilitate patient access to specialised care and orphan drugs (OD) in the public health sector in Spain. METHODS: Two Delphi rounds were completed. The questionnaire was based on a literature review and 2 focus groups. Agreement was sought on the desire (D) and prognosis (P) for the implementation within the next 5 years, on a 5-point Likert scale. Consensus was reached when >=75% participants chose agreement (1-2) or disagreement options (4-5). RESULTS: 82 experts on rare disease (RD) participated. Agreement on the D and P was reached in 66.07% statements: OD pricing review [absence of clinical effectiveness (D:85.37%; P:85.90%), target population increase (D:79.27%; P:91.03%)]; reference team definition of referral protocols and clinical practice guidelines (D: 97.56%; P: 89.74%); and a unified, usable, etiology-based registry (D:97.56%; P:84.62%). D and P assessment diverged in 32.14% items: creation of a specific funding system for OD (D: 97.56%; P: 60.25%); and a network of medical teams to coordinate the care of RD patients (D: 99%; P: 62%). CONCLUSIONS: The results have shown the need to promote dialogue between stakeholders, introduce European recommendation to national and regional Spanish policies and set up priorities and undertake actions to drive relevant changes in current medical practice in managing RD patients. PMID- 29572018 TI - Strategies for newborn screening for cystic fibrosis: A systematic review of health economic evaluations. AB - BACKGROUND: Early detection of cystic fibrosis through newborn screening has significant clinical benefits. Cost-effectiveness plays an important role in selecting the optimal screening strategy from the many available options. OBJECTIVES: The objectives of this study are (1) to summarize study estimates of cost-effectiveness of cystic fibrosis newborn screening (CFNBS) strategies as compared to other strategies, (2) to assess the quality of the studies identified, and (3) to identify determinants of cost-effectiveness. METHODS: Electronic databases were searched from 2007 to June 2017. Health economic evaluations describing the cost-effectiveness of two or more CFNBS strategies were included. RESULTS: Six health economic evaluations were found. Where included in the comparison, IRT/PAP consistently was the most cost-effective strategy in terms of cost per case detected or life years gained. However, some heterogeneity with respect to cut-off values used and the number of DNA mutations included in the screening strategies was observed, and the methodological quality differed considerably between studies. CONCLUSIONS: The evidence suggested that (i) all screening strategies are cost-effective as compared to the no-screening option and (ii) IRT-PAP seems to be the most cost-effective screening strategy towards CFNBS. Methodological and contextual differences of the individual studies make it difficult to derive strong conclusions from this evidence. Nevertheless, from a health-economic perspective, IRT-PAP should be included as an alternative when deciding on the screening strategy in the implementation of CFNBS.

PMID- 29572022 TI - Early fundoplication is associated with slower decline in lung function after lung transplantation in patients with gastroesophageal reflux disease. AB - OBJECTIVES: Gastroesophageal reflux disease (GERD) is prevalent after lung transplantation. Fundoplication slows lung function decline in patients with GERD, but the optimal timing of fundoplication is unknown. METHODS: We retrospectively reviewed patients who underwent fundoplication after lung transplantion at our center from April 2007 to July 2014. Patients were divided into 2 groups: early fundoplication (<6 months after lung transplantation) and late fundoplication (>=6 months after lung transplantation). Annual decline in percent predicted forced expiratory volume in 1 second (FEV1) was analyzed. RESULTS: Of the 251 patients who underwent lung transplantation during the study period with available pH data, 86 (34.3%) underwent post-transplantation fundoplication for GERD. Thirty of 86 (34.9%) had early fundoplication and 56 of 86 (65.1%) had late fundoplication. Median time from lung transplantation to fundoplication was 4.6 months (interquartile range, 2.0-5.2) and 13.8 months (interquartile range, 9.0-16.1) for the early and late groups, respectively. The median DeMeester score was comparable between groups. One-, 3-, and 5-year actuarial survival rates in the early group were 90%, 70%, and 70%, respectively; in the late group, these rates were 91%, 66%, and 66% (log rank P = .60). Three- and 5-year percent predicted FEV1 was lower in the late group by 8.9% (95% confidence interval, -30.2 to 12.38; P = .46) and 40.7% (95% confidence interval, -73.66 to -7.69; P = .019). A linear mixed model showed a 5.7% lower percent predicted FEV1 over time in the late fundoplication group (P < .001). CONCLUSIONS: In this study, patients with early fundoplication had a higher FEV1 5 years after lung transplantation. Early fundoplication might protect against GERD-induced lung damage in lung transplant recipients with GERD. PMID- 29572023 TI - Life with limb instead limb for life-selective perfusion safes extremities. PMID- 29572021 TI - A novel tissue treatment to reduce mineralization of bovine pericardial heart valves. AB - OBJECTIVE: With the increasing use of bioprostheses worldwide, continuous efforts have been made to improve tissue durability. We introduce a new treatment for bovine pericardium combining octanediol-ethanol based phospholipid removal with taurine-based glutaraldehyde neutralization and storage in an aldehyde-free solution (FREE). METHODS: Treated tissues were evaluated by mechanical and biochemical characterization, phospholipid content, aldehyde levels, cell cultures on pericardial samples (L929 fibroblasts and human umbilical vein endothelial cells), rat subcutaneous implantations, and long-term juvenile sheep mitral valve implantations (n = 3). Comparisons were made to glutaraldehyde-fixed bovine pericardium or to samples from commercially available biological valves (ie, Trifecta [St Jude Medical, Saint Paul, Minn] and Perimount Magna Ease [Edwards Lifesciences, Irvine, Calif]). RESULTS: FREE-treated pericardium had similar mechanical strength and biochemical properties as commercially available valves. Compared with glutaraldehyde-only samples, FREE-treated samples showed lower phospholipid levels (P < .01), significantly better growth of L929 fibroblasts, and lower calcification levels in rat subcutaneous implants (P < .01). Compared with samples from Linx- (Trifecta) and ThermaFix-treated (Perimount Magna Ease) valves, similar low levels of phospholipids were observed as were similar low calcification levels in subcutaneous implants, but tissue extractions from FREE-treated samples showed the lowest levels of extracted aldehydes (P < .01). Mitral implants of FREE-treated valves in juvenile sheep had excellent hemodynamic behavior without any sign of degeneration or calcification at 5 months. CONCLUSIONS: The new FREE treatment combines an adequate phospholipid reduction and aldehyde neutralization with storage in an aldehyde free solution. This combination enhances the anticalcification properties and may thereby improve long-term durability of the tissue. PMID- 29572024 TI - A unique computed tomographic finding: Dissection?

PMID- 29572027 TI - A novel multiple biomarker panel for the early detection of high-grade serous ovarian carcinoma. AB - INTRODUCTION: Since the majority of patients are diagnosed at an advanced stage, ovarian cancer remains the most lethal gynecologic malignancy. There is no single biomarker with the sensitivity and specificity required for effective cancer screening; therefore, we investigated a panel of novel biomarkers for the early detection of high-grade serous ovarian carcinoma. METHODS: Twelve serum biomarkers with high differential gene expression and validated antibodies were selected: IL-1Ra, IL-6, Dkk-1, uPA, E-CAD, ErbB2, SLPI, HE4, CA125, LCN2, MSLN, and OPN. They were tested using Simple PlexTM, a multi-analyte immunoassay platform, in samples collected from 172 patients who were either healthy, had benign gynecologic pathologies, or had high-grade serous ovarian adenocarcinomas. The receiver operating characteristic (ROC) curve, ROC area under the curve (AUC), and standard error (SE) of the AUC were obtained. Univariate ROC analyses and multivariate ROC analyses with the combination of multiple biomarkers were performed. RESULTS: The 4-marker panel consisting of CA125, HE4, E-CAD, and IL-6 had the highest ROC AUC. When evaluated for the ability to distinguish early stage ovarian cancer from a non-cancer control, not only did this 4-marker panel (AUC=0.961) performed better than CA 125 alone (AUC=0.851; P=0.0150) and HE4 alone (AUC=0.870; P=0.0220), but also performed significantly better than the 2- marker combination of CA125+HE4 (AUC=0.922; P=0.0278). The 4-marker panel had the highest average sensitivity under the region of its ROC curve corresponding to specificity ranging from 100% down to ~95%. CONCLUSION: The four-marker panel, CA125, HE4, E-CAD, and IL-6, shows potential in detecting serous ovarian cancer at earlier stages. Additional validation studies using the biomarker combination in ovarian cancer patients are warranted. PMID- 29572029 TI - Prognostic implication of programmed cell death 1 protein and its ligand expressions in endometrial cancer. AB - OBJECTIVE: Monoclonal antibodies targeting programmed cell death-1 (PD 1)/programmed death ligand 1 (PD-L1) demonstrated promising clinical response. The predictive/prognostic value of PD-1/PD-L1 immunohistochemistry (IHC) has been evaluated in many cancer types. However, the prognostic value of PD-1/PD-L1 IHC has not been evaluated in endometrial cancer. METHODS: We conducted a retrospective study to quantify the IHC CD8, PD-1, and PD-L1 expressions in immune cells at center of tumor (CT), invasive margin (IM), and/or tumor cell in 183 primary endometrial cancer samples from a single cohort, followed by their reciprocal combinations, including compartmental differences, and correlated them with overall survival (OS) and progression-free survival (PFS). RESULTS: In repeated Cox multivariable models adjusted by clinicoimmunopathologic factors, high CT-PD-L1 was an independent adverse prognostic factor for PFS in all patients and in the microsatellite-stable subgroup. Immune marker ratios revealed independently shorter PFS for high CT-PD-L1/CT-CD8 and CT-PD-L1/CT-PD-1 ratios. Classification of endometrial cancer into four groups based on CT-CD8 and CT-PD L1 revealed significantly different survival among groups. CONCLUSIONS: The high PD-L1/CD8 ratio and the high expression of PD-L1 on immune cells were independent poor prognostic factors for PFS in endometrial cancer, providing insights into the tumor microenvironment. PMID- 29572030 TI - Integrated analysis of HPV-mediated immune alterations in cervical cancer. AB - OBJECTIVE: Human papillomavirus (HPV) infection is the primary cause of cervical cancer. HPV-mediated immune alterations are known to play crucial roles in determining viral persistence and host cell transformation. We sought to thoroughly understand HPV-directed immune alterations in cervical cancer by exploring publically available datasets. METHODS: 130 HPV positive and 7 HPV negative cervical cancer cases from The Cancer Genome Atlas were compared for differences in gene expression levels and functional enrichment. Analyses for copy number variation (CNV) and genetic mutation were conducted for differentially expressed immune genes. Kaplan-Meier analysis was performed to assess survival and relapse differences across cases with or without alterations of the identified immune signature genes. RESULTS: Genes up-regulated in HPV positive cervical cancer were enriched for various gene ontology terms of immune processes (P=1.05E-14~1.00E-05). Integrated analysis of the differentially expressed immune genes identified 9 genes that displayed either CNV, genetic mutation and/or gene expression changes in at least 10% of the cases of HPV positive cervical cancer. Genomic amplification may cause elevated levels of these genes in some HPV positive cases. Finally, patients with alterations in at least one of the nine signature genes overall had earlier relapse compared to those without any alterations. The altered expression of either TFRC or MMP13 may indicate poor survival for a subset of cervical cancer patients (P=1.07E-07). CONCLUSIONS: We identified a novel immune gene signature for HPV positive cervical cancer that is potentially associated with early relapse of cervical cancer. PMID- 29572031 TI - Helicase POLQ-like (HELQ) as a novel indicator of platinum-based chemoresistance for epithelial ovarian cancer. AB - OBJECTIVE: To investigate the role of HELQ in chemo-resistance of epithelial ovarian carcinoma (EOC), which is a critical factor of patients' prognosis. METHODS: Immunohistochemistry, survival analysis of our 87 EOC patients and bioinformatics analysis of The Cancer Genome Atlas (TCGA) datasets (Nature, 2011) disclosed the clinical importance of HELQ expression. Quantitative reverse transcription polymerase chain reaction (qRT-PCR), and Western Blot analyses of EOC tissue were used to confirm it. Ectopic overexpression and RNA interference knockdown of HELQ were carried out in OVCAR3 and A2780 cell lines, respectively, to determine the effect of altered HELQ expression on cellular response to cisplatin by CCK8 assay. The DNA repair capacity of these cells was evaluated by using host-cell reactivation assay. Western Blot analyses were carried out to determine the effect of HLEQ on the DNA repair genes by using cells with altered HELQ expression. RESULTS: HELQ expression associates with response of EOC patients to platinum-based chemotherapy and their overall survival (OS), disease free survival (DFS). HELQ overexpression or knockdown, respectively, increased and decreased the cellular resistance to cisplatin, DNA repair activity, and expression of DNA repair proteins of Nucleotide excision repair (NER) pathway. CONCLUSIONS: HELQ plays an important role in regulating the expression of DNA repair proteins NER pathway which, in turn, contributes to cellular response to cisplatin and patients' response to platinum-based chemotherapy. Our results demonstrated that HELQ could serve as a novel indicator for chemo-resistance of EOC, which can predict the prognosis of the disease. PMID- 29572032 TI - Chloride imbalance is involved in the pathogenesis of optic neuritis in neuromyelitis optica. AB - Chloride imbalance between the serum and the cerebrospinal fluid (CSF) has been recently shown to exist in the acute phase of neuromyelitis optica (NMO). In this report, we studied the relation between the quotient of chloride (QCl) and the severity of optic neuritis (ON) in NMO patients. There was a positive correlation (R = 0.67; p < 0.05) between QCl and the length of ON-lesion. The visual prognosis also showed a positive correlation with QCl in the acute phase (R = 0.58; p < 0.05). These results support the theory that chloride imbalance between serum and CSF may trigger the ON in NMO spectrum disorders. PMID- 29572033 TI - Role of the cell membrane interface in modulating production and uptake of Alzheimer's beta amyloid protein. AB - The beta amyloid protein (Abeta) plays a central role in Alzheimer's disease (AD) pathogenesis and its interaction with cell membranes in known to promote mutually disruptive structural perturbations that contribute to amyloid deposition and neurodegeneration in the brain. In addition to protein aggregation at the membrane interface and disruption of membrane integrity, growing reports demonstrate an important role for the membrane in modulating Abeta production and uptake into cells. The aim of this review is to highlight and summarize recent literature that have contributed insight into the implications of altered membrane composition on amyloid precursor protein (APP) proteolysis, production of Abeta, its internalization in to cells via permeabilization and receptor mediated uptake. Here, we also review the various membrane model systems and experimental tools used for probing Abeta-membrane interactions to investigate the key mechanistic aspects underlying the accumulation and toxicity of Abeta in AD. PMID- 29572034 TI - Solubilization kinetics determines the pulsatory dynamics of lipid vesicles exposed to surfactant. AB - We establish a biophysical model for the dynamics of lipid vesicles exposed to surfactants. The solubilization of the lipid membrane due to the insertion of surfactant molecules induces a reduction of membrane surface area at almost constant vesicle volume. This results in a rate-dependent increase of membrane tension and leads to the opening of a micron-sized pore. We show that solubilization kinetics due to surfactants can determine the regime of pore dynamics: either the pores open and reseal within a second (short-lived pore), or the pore stays open up to a few minutes (long-lived pore). First, we validate our model with previously published experimental measurements of pore dynamics. Then, we investigate how the solubilization kinetics and membrane properties affect the dynamics of the pore and construct a phase diagram for short and long-lived pores. Finally, we examine the dynamics of sequential pore openings and show that cyclic short-lived pores occur with a period inversely proportional to the solubilization rate. By deriving a theoretical expression for the cycle period, we provide an analytical tool to estimate the solubilization rate of lipid vesicles by surfactants. Our findings shed light on some fundamental biophysical mechanisms that allow simple cell-like structures to sustain their integrity against environmental stresses, and have the potential to aid the design of vesicle-based drug delivery systems.

PMID- 29572036 TI - Predictors of Treatment Failure After 2-Stage Reimplantation for Infected Total Knee Arthroplasty: A 2- to 10-Year Follow-Up. AB - BACKGROUND: The aim of this study is to identify risk factors which may lead to treatment failure following 2-stage reimplantation for chronic infected total knee arthroplasty (TKA). METHODS: We retrospectively reviewed 106 patients (108 knees) who underwent consecutive 2-stage revision for chronic PJI of the knee at our institution between January 2005 and December 2015. A total of 31 risk factors, including patient characteristics, comorbidities, surgical variables, and microbiology data, were collected. Kaplan-Meier survival and Cox regression analyses were used to calculate survival rates and adjusted hazard ratios (HRs) of treatment failure. RESULTS: Within the cohort, 16 of the 108 2-stage reimplantations (14.8%) had treatment failure. The treatment success for 2-stage reimplantation was 91% (95% confidence interval [CI] 0.8-1.0) at 2 years and 84% (95% CI 0.8-0.9) at 5 and 10 years. Multivariate analysis provided the strongest predictors of treatment failure, including body mass index >=30 kg/m2 (adjusted HR 9.3, 95% CI 2.7-31.8, P < .001), operative time >4 hours (adjusted HR 11.3, 95% CI 3.9-33.1, P < .001), gout (adjusted HR 13.8, 95% CI 2.9-66.1, P = .001), and the presence of Enterococcus species during resection arthroplasty (adjusted HR 14.1, 95% CI 2.6-76.3, P = .002). CONCLUSION: Our study identified 4 potential risk factors that may predict treatment failure following 2-stage revision for chronic knee PJI. This finding may be useful when counseling patients regarding the treatment success and prognosis of 2-stage reimplantation for infected TKA. PMID- 29572037 TI - Prognostic Factors for Success After Irrigation and Debridement With Modular Component Exchange for Infected Total Knee Arthroplasty. AB - BACKGROUND: Irrigation and debridement with modular component exchange (IDMCE) can treat prosthetic joint infection (PJI) after total knee arthroplasty (TKA). Compared to 2-stage revision, IDMCE is associated with lower morbidity but may carry higher infection recurrence rates. We aimed to identify prognostic factors associated with successful IDMCE in patients with PJI. METHODS: We identified 99 consecutive patients who underwent IDMCE following TKA PJI at a tertiary academic medical center from November 2009 through January 2016. Examined variables included age, gender, symptom duration, body mass index, Charlson comorbidity index, total protein, albumin, hemoglobin A1c, erythrocyte sedimentation rate (ESR), C-reactive protein, white blood cell count, gram stain results, final cultures, and use of long-term antibiotic suppression. Success was defined as no further operation on the ipsilateral knee. We used t tests and chi-square analyses to determine whether each preoperative factor was associated with IDMCE reoperation. RESULTS: At mean follow-up of 2.6 years, 64 patients who underwent IDMCE were defined as successful. Thirty-five patients required one or more additional procedures for recurrent infection; of these, 20 patients underwent 2 stage revision. Patients with symptom duration of less than 2 days avoided additional surgery in 88% of cases. Elevated ESR >47 mm/h was the only variable associated with reoperation (P = .005). There were no associations among the other examined variables. CONCLUSION: Using IDMCE for PJI after TKA required reoperation in 35% of cases. Elevated preoperative ESR laboratory values and duration of symptoms >2 days were associated with reoperation. PMID- 29572038 TI - High Efficiency Particulate Air Filters Do Not Affect Acute Infection Rates During Primary Total Joint Arthroplasty Using Forced Air Warmers. AB - BACKGROUND: Studies have suggested that forced-air warmers (FAWs) increase contamination of the surgical site. In response, FAWs with high efficiency particulate air filters (FAW-HEPA) were introduced. This study compared infection rates following primary total joint arthroplasty (TJA) using FAW and FAW-HEPA. METHODS: Primary TJA patients at a single healthcare system were retrospectively reviewed. A total of 5405 THA (n = 2419) and TKA (n = 2986) consecutive cases in 2013 and 2015 were identified. Patients in 2013 (n = 2792) had procedures using FAW, while FAW-HEPA was used in 2015 (n = 2613). The primary outcome was overall infection rate within 90-days. Sub-categorization of infections as periprosthetic joint infection (PJI) or surgical site infection (SSI) was also conducted. PJI was defined as reoperation with arthrotomy or meeting Musculoskeletal Infection Society (MSIS) criteria. SSI was defined as wound complications requiring antibiotics or irrigation/debridement. RESULTS: The FAW and FAW-HEPA groups had similar rates of overall infection (1.65% [n = 46] vs 1.61% [n = 42], P > .99), SSI (1.18% [n = 33] vs 0.84% [n = 22], P = .27), and PJI (0.47% [n = 13] vs 0.77% [n = 20], P = .22). Regression models did not show FAW to be an independent risk factor for increased overall infection (odds ratio [OR] 1.00, 95% confidence interval [CI] 0.65-1.57, P = .97), SSI (OR 1.47, 95% CI 0.83-2.58, P = .18), or PJI (OR 0.53, 95% CI 0.25-1.13, P = .09). CONCLUSION: FAW were not correlated with a higher risk of overall infection, SSI, or PJI during TJA when compared to FAW-HEPA devices. PMID- 29572039 TI - Blood zinc levels and cognitive and functional evaluation in non-demented older patients. AB - A complete battery of geriatric and psychometric tests was used to determine whether plasma-borne zinc (Zn), a key ion in neuroplasticity, can be associated with the severity of functional, psychological and cognitive impairment in non demented older individuals. There was a significant positive correlation between plasma Zn levels and the concentration subcategory measured with the Mini-Mental State Examination (MMSE) test (p < 0.001), but not the total MMSE score, and the levels were significantly reduced in polymedicated patients (defined as concurrent administration of >5 drugs). No correlations were found between plasma Zn levels and depressive symptoms measured with the Yesavage scale for geriatric depression or the Barthel Index - a measurement of the ability of individuals to perform the activities of daily living. Depressive symptoms were associated with poor sleep quality and polymedication (p < 0.001 and p < 0.05, respectively). Our results suggest that peripheral Zn concentration may play a role in the physiopathology of some domain of cognitive function. No correlation to depressive symptoms in the geriatric population under antidepressant drug treatment was observed. However, further studies are needed to understand the relationship between circulating Zn and concentration deficits in order to determine whether Zn represents a candidate early biomarker for cognitive impairment.

AB - Dorsal fracture-dislocations of the proximal interphalangeal (PIP) joint of the long fingers are in most cases unstable. They require surgery, whose primary aim is to restore and maintain articular congruency. While numerous techniques exist to treat these injuries, none have been shown to be superior to any of the others in terms of outcomes and complications. The least invasive techniques should be used as much as possible. We report here a rare case of incarceration of the flexor tendons in the PIP fracture which required open surgery. PMID- 29572041 TI - Naloxone access for Emergency Medical Technicians: An evaluation of a training program in rural communities. AB - INTRODUCTION: Opioid-related overdose death rates in rural communities in the United States are much higher than their urban counterparts. However, basic life support (BLS) personnel, who are more common in rural areas, have much lower rates of naloxone administration than other levels of emergency medical services (EMS). Training and equipping basic level Emergency Medical Technician (EMTs) to administer naloxone for an opioid overdose could yield positive outcomes. METHODS: Following a legislative change that allowed EMTs to administer naloxone in one rural state, we evaluated an EMT training program by examining EMTs' opioid overdose knowledge and attitudes before and after the training. RESULTS: One-hundred-seventeen rural EMTs participated the training. They demonstrated statistically significant improvements on almost all of the knowledge questions after the training (p's = 0.0469 to <0.0001). The opioid overdose competency and concern scales showed statistically significant improvement (p < 0.0001) and reduction (p < 0.0001), respectively. Furthermore, statistically significant changes in knowledge and opinions of state law regarding naloxone administration were observed. Significantly more EMTs supported the idea of expanding naloxone to people at risk for overdose (p = 0.0026) after the training. CONCLUSIONS: At a time when states are passing legislation to expand first responders' access to naloxone, this study provides evidence about authorizing EMTs to administer naloxone.

AB - Daptomycin has shown activity against a wide range of Gram-positive bacteria; however, the approved dosages usually seem insufficient for critically ill patients. The aim of this study was to develop a population pharmacokinetic model for daptomycin in critically ill patients and to estimate the success of the therapy by applying pharmacokinetic/pharmacodynamic (PK/PD) criteria. Sixteen intensive care unit patients were included, four of whom underwent continuous renal replacement therapies (CRRT). Blood and, when necessary, effluent samples were drawn after daptomycin administration at previously defined time points. A population approach using NONMEM 7.3 was performed to analyse data. Monte Carlo simulations were executed to evaluate the suitability of different dosage regimens. The probabilities of achieving the PK/PD target value associated with treatment success (ratio of the area under the plasma concentration-time curve over 24 h divided by the minimum inhibitory concentration (AUC24/MIC >= 666)) and to reach daptomycin concentrations linked to toxicity (minimum concentration at steady-state (Cminss) >= 24.3 mg/L) were calculated. The pharmacokinetics of daptomycin was best described by a one-compartment model. Elimination was conditioned by the creatinine clearance (Clcr) and also by the extra-corporeal clearance when patients were subjected to continuous renal replacement therapy (CRRT). The PK/PD analysis confirmed that 280- and 420-mg/d dosages would not be enough to achieve high probabilities of target attainment for MIC values >= 1 mg/L in patients with Clcr >= 60 mL/min or in subjects with lower Clcrs but receiving CRRT. In these patients, higher dosages (560-840 mg/d) should be needed. When treating infections due to MIC values >= 4 mg/L, even the highest dose would be insufficient. PMID- 29572043 TI - Bioluminescence imaging increases in vivo screening efficiency for antifungal activity against device-associated Candida albicans biofilms. AB - Fungal infections are a major problem for a growing number of mostly immunocompromised patients. Candida albicans is an important human fungal pathogen causing mucosal and deep tissue infections, of which the majority are associated with biofilm formation on medical implants. Animal models that are currently in use to test antifungal drugs are limited to ex vivo analyses, requiring host sacrifice that excludes longitudinal monitoring of dynamic processes during biofilm formation in the live host. As a solution, we introduce non-invasive, dynamic imaging and quantification of C. albicans biofilm formation in vivo and subsequent evaluation of treatment efficacy against these biofilms using bioluminescent C. albicans in a catheter-associated mouse model. Bioluminescence imaging (BLI) allowed us to evaluate baseline biofilm load before the start of therapy, which is necessary for correct evaluation and interpretation of antibiofilm efficacy in vivo. Moreover, we demonstrate that this BLI approach monitors the antibiofilm activity of different antifungal agents efficiently in vitro and in vivo. In this study, BLI revealed superior antibiofilm activity for echinocandins compared with amphotericin B and fluconazole. In vitro, anidulafungin showed the highest antibiofilm activity, followed by micafungin and caspofungin. In vivo, caspofungin significantly decreased the biofilm fungal load, as documented by the lower BLI signal and confirmed by CFU counts. In conclusion, this BLI approach increases the power and efficiency of screening and validation of antimycotics both under in vitro and in vivo conditions, thereby refining pre-clinical therapy studies. PMID- 29572044 TI - Identification of genome regions determining semen quality in Holstein-Friesian bulls using information theory. AB - Use of information theory can be an alternative statistical approach to detect genome regions and candidate genes that are associated with livestock traits. The aim of this study was to verify the validity of the SNPs effects on some semen quality variables of bulls using entropy analysis. Records from 288 Holstein Friesian bulls from one AI station were included. The following semen quality variables were analyzed: CASA kinematic variables of sperm (total motility, average path velocity, straight line velocity, curvilinear velocity, amplitude of lateral head displacement, beat cross frequency, straightness, linearity), sperm membrane integrity (plazmolema, mitochondrial function), sperm ATP content. Molecular data included 48,192 SNPs. After filtering (call rate = 0.95 and MAF = 0.05), 34,794 SNPs were included in the entropy analysis. The entropy and conditional entropy were estimated for each SNP. Conditional entropy quantifies the remaining uncertainty about values of the variable with the knowledge of SNP. The most informative SNPs for each variable were determined. The computations were performed using the R statistical package. A majority of the loci had relatively small contributions. The most informative SNPs for all variables were mainly located on chromosomes: 3, 4, 5 and 16. The results from the study indicate that important genome regions and candidate genes that determine semen quality variables in bulls are located on a number of chromosomes. Some detected clusters of SNPs were located in RNA (U6 and 5S_rRNA) for all the variables for which analysis occurred. Associations between PARK2 as well GALNT13 genes and some semen characteristics were also detected. PMID- 29572045 TI - An update on semen collection, preservation and artificial insemination in the dromedary camel (Camelus dromedarius). AB - Artificial insemination (AI) in domestic animals is an important tool to maximise the use of genetically superior males and thereby insure rapid genetic progress. However, the application of AI in camelids has been hindered by the difficulties involved in collecting, as well as handling the semen due to the viscous nature of the seminal plasma. This review describes the challenges of semen collection and discusses the role of seminal plasma as well as the reasons for the viscosity and how to liquefy it so that ejaculates can be more accurately evaluated. It also reports on the use of various extenders used for liquid storage of fresh and chilled semen and how pregnancy rates are affected by numbers of spermatozoa inseminated, site of insemination and timing of insemination in relation to GnRH injection given to induce ovulation. In addition, this paper reviews the latest research in cryopreservation of camel semen and addresses the various problems involved and possible improvements that can be made so that pregnancy rates can be increased with frozen semen. PMID- 29572046 TI - Neurotoxicity screening of new psychoactive substances (NPS): Effects on neuronal activity in rat cortical cultures using microelectrode arrays (MEA). AB - While the prevalence and the use of new psychoactive substances (NPS) is steadily increasing, data on pharmacological, toxicological and clinical effects is limited. Considering the large number of NPS available, there is a clear need for efficient in vitro screening techniques that capture multiple mechanisms of action. Neuronal cultures grown on multi-well microelectrode arrays (mwMEAs) have previously proven suitable for neurotoxicity screening of chemicals, pharmaceuticals and (illicit) drugs. We therefore used rat primary cortical cultures grown on mwMEA plates to investigate the effects of eight NPS (PMMA, alpha-PVP, methylone, MDPV, 2C-B, 25B-NBOMe, BZP and TFMPP) and two 'classic' illicit drugs (cocaine, methamphetamine) on spontaneous neuronal activity. All tested drugs rapidly and concentration-dependently decreased the weighted mean firing rate (wMFR) and the weighted mean burst rate (wMBR) during a 30 min acute exposure. Of the 'classic' drugs, cocaine most potently inhibited the wMFR (IC50 9.8 MUM), whereas methamphetamine and the structurally-related NPS PMMA were much less potent (IC50 100 MUM and IC50 112 MUM, respectively). Of the cathinones, MDPV and alpha-PVP showed comparable IC50 values (29 MUM and 21 MUM, respectively), although methylone was 10-fold less potent (IC50 235 MUM). Comparable 10-fold differences in potency were also observed between the hallucinogenic phenethylamines 2C-B (IC50 27 MUM) and 25B-NBOMe (IC50 2.4 MUM), and between the piperazine derivatives BZP (IC50 161 MUM) and TFMPP (IC50 19 MUM). All drugs also inhibited the wMBR and concentration-response curves for wMBR and wMFR were comparable. For most drugs, IC50 values are close to the estimated human brain concentrations following recreational doses of these drugs, highlighting the importance of this efficient in vitro screening approach for classification and prioritization of emerging NPS. Moreover, the wide range of IC50 values observed for these and previously tested drugs of abuse, both within and between different classes of NPS, indicates that additional investigation of structure-activity relationships could aid future risk assessment of emerging NPS. PMID- 29572047 TI - Contamination trends and factors affecting the transfer of hexabromocyclododecane diastereomers, tetrabromobisphenol A, and 2,4,6-tribromophenol to breast milk in Japan. AB - This study investigated contamination trends and factors affecting the levels of brominated flame retardants (BFRs), including hexabromocyclododecane (HBCD) diastereomers, tetrabromobisphenol A (TBBP-A), and 2,4,6-tribromophenol (2,4,6 TBP), in breast milk in Japan. Breast milk samples (n = 64) were collected from mothers living in six prefectures in Japan. The mean concentrations were 2.2, 0.19, 0.29, 3.0, and 0.59 ng/g lipid weight for alpha-HBCD, beta-HBCD, gamma HBCD, TBBP-A, and 2,4,6-TBP, respectively. Based on the previous studies, the levels of SigmaHBCD in Japanese women's milk appear to be increasing, and the levels of TBBP-A are higher than those in other Asian countries. Although SigmaHBCD were not correlated to phenolic BFRs, the concentration of beta-HBCD was significantly correlated to the concentrations of TBBP-A (r = 0.440, p < 0.01) and 2,4,6-TBP (r = 0.320, p < 0.01). The concentration of gamma-HBCD increased significantly with maternal age (r = 0.378, p < 0.01), but the concentrations of the other analytes were not dependent on age. The concentration of alpha-HBCD was higher in primiparae than in multiparae (p < 0.05), while TBBP A was higher in multiparae. No significant correlation was found between the phenolic BFR levels in milk and mothers' age, working place, and drinking/smoking habits. These results suggest that exposure to alpha- and gamma-HBCD diastereomers could be affected by maternal age and parity, respectively, because of their different kinetics and sources. Therefore, these factors should be considered when conducting infant risk assessments. PMID- 29572048 TI - Quality and Efficiency Improvement Tools for Every Radiologist.

PMID- 29572049 TI - A Radiomics Signature in Preoperative Predicting Degree of Tumor Differentiation in Patients with Non-small Cell Lung Cancer. AB - RATIONALE AND OBJECTIVES: Poorly differentiated non-small cell lung cancer (NSCLC) indicated a poor prognosis and well-differentiated NSCLC indicates a noninvasive nature and good prognosis. The purpose of this study was to build and validate a radiomics signature to predict the degree of tumor differentiation (DTD) for patients with NSCLC. MATERIALS AND METHODS: A total of 487 patients with pathologically diagnosed NSCLC were retrospectively included in our study. Five hundred ninety-one radiomics features were extracted from each tumor from the contrast-enhanced computed tomography images. A minimum redundancy maximum relevance algorithm and a logistic regression model were used for dimension reduction, feature selection, and radiomics signature building. The performance of the radiomics signature was assessed using receiver operating characteristic analysis, and the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy were calculated to quantify the association between a signature and DTD. An independent validation set contained 184 consecutive patients with NSCLC. RESULTS: A nine-radiomics-feature-based signature was built and it could differentiate low and high DTDs in the training set (AUC = 0.763, sensitivity = 0.750, specificity = 0.665, and accuracy = 0.687), and the radiomics signature had good discrimination performance in the validation set (AUC = 0.782, sensitivity = 0.608, specificity = 0.752, and accuracy = 0.712). CONCLUSIONS: A radiomics signature based on contrast-enhanced computed tomography imaging is a potentially useful imaging biomarker for differentiating low from high DTD in patients with NSCLC. PMID- 29572050 TI - Variability of CT Airways Measurements in COPD Patients Between Morning and Afternoon: Comparisons to Variability of Spirometric Measurements. AB - RATIONALE AND OBJECTIVES: Computed tomography (CT) airways measurements can be used as surrogates to spirometric measurements for assessing bronchodilation in a particular patient with chronic obstructive pulmonary disease. Although spirometric measurements show variations within the opening hours of a hospital department, we aimed to compare the variability of CT airways measurements between morning and afternoon in patients with chronic obstructive pulmonary disease to that of spirometric measurements. MATERIALS AND METHODS: Twenty patients had pulmonary function tests and CT around 8 am and 4 pm. Luminal area (LA) and wall thickness (WT) of third and fourth generation airways were measured twice by three readers. The percentage of airway area occupied by the wall (WA%) and the square root of wall area at an internal perimeter of 10 mm (?WAPi10) were calculated. The effects of examination time, reader, and measurement session on CT airways measurements were assessed, and the variability of these measurements was compared to that of spirometric measurements. RESULTS: Variability of LA3rd and LA4th was greater than that of spirometric measurements (P values ranging from <.001 to .033). There was no examination time effect on ?WAPi10, WT3rd, LA4th, or WA%4th (P values ranging from .102 to .712). There was a reader effect on all CT airways measurements (P values ranging from <.001 to .028), except in WT3rd (P> .999). There was no effect of measurement session on any CT airway measurement (P values ranging from .535 to >.999). CONCLUSION: As the variability of LA3rd and LA4th is greater than that of spirometric measurements, clinical studies should include cohorts with larger numbers of patients when considering LA than when considering spirometric measurements as end points. PMID- 29572051 TI - Botulinum toxin type A and gabapentin attenuate postoperative pain and NK1 receptor internalization in rats. AB - Treatment of postoperative pain remains a challenge in clinic. Botulinum toxin type A (BoNT/A) and gabapentin regulate the release of neurotransmitters from primary afferent neurons, but their effects of on postoperative pain are not clear. In the current study, using pain behavioral tests, Western blot analysis, and immunocytochemistry, we examined whether BoNT/A, alone or in combination with intrathecal gabapentin, inhibited pain hypersensitivity and attenuated the increase in neurokinin 1 (NK1) receptor internalization in dorsal horn neurons after plantar incision. Our data showed that pretreatment of rats with an intraplantar (2 U) 24 h before plantar incision or intrathecal (0.5 U) injection of BoNT/A 48 h before plantar incision induced a prolonged (3-5 days) decrease in pain scores and mechanical hypersensitivity, as compared to those observed with saline pretreatment. Both intraplantar and intrathecal BoNT/A pretreatment reduced synaptosomal-associated protein 25 levels in the ipsilateral lumbar dorsal root ganglia and spinal cord dorsal horn, and attenuated the increase in NK1 receptor internalization in dorsal horn neurons. Intrathecal administration of a sub-effective dose of gabapentin (50 MUg) with BoNT/A (0.5 U) induced greater inhibition of pain hypersensitivity and NK1 receptor internalization than BoNT/A alone. These findings suggest that pretreatment with BoNT/A, alone or in combination with intrathecal gabapentin, may present a promising multimodal analgesia regimen for postoperative pain treatment. PMID- 29572052 TI - Long noncoding RNA DANCR mediates cisplatin resistance in glioma cells via activating AXL/PI3K/Akt/NF-kappaB signaling pathway. AB - Malignant glioma is an aggressive type of brain tumor with poor prognosis and mostly incurable. Although cisplatin is used for adjuvant chemotherapy against glioma, intrinsic and acquired resistance restricts the application of cisplatin. Long noncoding RNA (lncRNA) DANCR is reported to regulate the differentiation and progression of several cancers. However, whether DANCR participates in cisplatin resistance of glioma is still unknown. In this study, we found that DANCR expression was negatively correlated with cisplatin sensitivity in glioma cells. Gain-of and loss-of function assays revealed that DNACR attenuated cisplatin induced cell proliferation inhibition in vitro and xenograft growth suppression in vivo. Furthermore, DNACR also attenuated cisplatin-induced cell apoptosis in vitro and in vivo. Mechanistically, we found that DANCR upregulated AXL via competitively binding miR-33a-5p, miR-33b-5p, miR-1-3p, miR-206, and miR-613. Through upregulating AXL, DANCR activated PI3K/Akt/NF-kappaB signaling pathway in glioma cells. Inhibiting AXL/PI3K/Akt/NF-kappaB signaling pathway reversed the effects of DANCR on cisplatin resistance. In conclusion, we identified a cisplatin-resistance associated lncRNA DANCR. DANCR promotes cisplatin resistance via activating AXL/PI3K/Akt/NF-kappaB signaling pathway in glioma. Our data suggested that DANCR would be a potential biomarker for predicting cisplatin sensitivity and a therapeutic target for enhancing cisplatin efficacy in glioma. PMID- 29572053 TI - Exposure to far-infrared rays attenuates methamphetamine-induced recognition memory impairment via modulation of the muscarinic M1 receptor, Nrf2, and PKC. AB - We demonstrated that activation of protein kinase Cdelta (PKCdelta) and inactivation of the glutathione peroxidase-1 (GPx-1)-dependent systems are critical for methamphetamine (MA)-induced recognition memory impairment. We also demonstrated that exposure to far-infrared rays (FIR) causes induction of the glutathione (GSH)-dependent system, including induction of the GPx-1 gene. Here, we investigated whether exposure to FIR rays affects MA-induced recognition memory impairment and whether it modulates PKC, cholinergic receptors, and the GSH-dependent system. Because the PKC activator bryostatin-1 mainly induces PKCalpha, PKCepsilon, and PKCdelta, we assessed expression of these proteins after MA treatment. MA treatment selectively increased PKCdelta expression and its phosphorylation. Exposure to FIR rays significantly attenuated MA-induced increases in PKCdelta phosphorylation. Importantly, bryostatin-1 potentiated MA induced phosphorylation of PKCdelta. MA treatment significantly decreased M1, M3, and M4 muscarinic acetylcholine receptors (mAChRs) and beta2 nicotinic acetylcholine receptor expression. Of these, the decrease was most pronounced in M1 mAChR. Exposure to FIR significantly attenuated MA-induced decreases in the M1 mAChR and phospho-ERK1/2, while it facilitated Nrf2-dependent GSH induction. Dicyclomine, an M1 mAChR antagonist, and l-buthionine-(S, R)-sulfoximine (BSO), an inhibitor of GSH synthesis, counteracted against the protective potentials mediated by FIR. More importantly, the memory-enhancing potential of FIR rays was significantly counteracted by bryostatin-1, dicyclomine, and BSO. Our results suggest that exposure to FIR rays attenuates MA-induced impairment in recognition memory via up-regulation of M1 mAChR, Nrf2-dependent GSH induction, and ERK1/2 phosphorylation by inhibiting PKCdelta phosphorylation by bryostatin-1.

Patients with WAGR syndrome and Wilms' tumor have risk of contralateral tumor and are a group of patients benefitted by nephron-sparing surgery (NSS). Whereas laparoscopic NSS has been attempted in such patients, due to the inherent technical limitations it has failed to gain popularity. Robotic approach for NSS overcomes limitations of movement and dexterity occurring with laparoscopic approach. However, the existing literature in robotic NSS in children is very limited. We present the first report of robotic approach for NSS in a child with WAGR syndrome. PMID- 29572055 TI - Prospective Evaluation of Predictors of Testis Atrophy After Surgery for Testis Torsion in Children. AB - OBJECTIVE: To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of testis, and intraoperative testis color to future testis atrophy after acute testicular torsion. METHODS: Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. RESULTS: Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant testis volume loss in follow-up compared with normal testis. All patients with a black or hemorrhagic testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected testis volume in follow-up. CONCLUSION: Based on the high atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with testis atrophy. Red scrotal skin was not a reliable predictor of atrophy and should not delay exploration. PMID- 29572056 TI - The Impact of the Choosing Wisely Campaign in Urology. AB - OBJECTIVE: To determine if 3 of the Canadian Urological Association's Choosing Wisely recommendations (released in 2013-2014) related to urologic care altered physician and patient behavior. METHODS: Administrative data from Ontario, Canada between 2008 and 2017 was used. We identified 3 cohorts: First, we determined how many men >66 years of age had a serum testosterone level before starting testosterone therapy. Second, we determined how many boys undergoing an orchiopexy underwent abdominal imaging before their surgery. Third, we determined how many men with low risk prostate cancer underwent a Bone Scan after diagnosis. Piece-wise linear regression was used to evaluate for a significant change after Choosing Wisely. RESULTS: We identified 13,113 men who had their initial prescription for testosterone filled. Serum testosterone measurement increased over time, from approximately 43% to 68%. There were 9319 boys who underwent an orchiopexy. The use of pre-orchiopexy ultrasound was generally stable (approximately 55%). We identified 27,174 men with low risk prostate cancer. The use of bone scans after diagnosis decreased over time from approximately 24% to 20%. In all 3 of these groups, there was no significant change after Choosing Wisely (P = .74, P = .70, P = .72 respectively). CONCLUSION: In Ontario, there was no evidence of a significant change in 3 practice patterns that were featured in Choosing Wisely Urology recommendations. Further thought may be needed on how to translate these and future recommendations into behavior change. PMID- 29572057 TI - Reply by the Authors. PMID- 29572058 TI - Laparoscopic-assisted Versus Open Appendicovesicostomy Procedure in Patients With Prior Abdominal Surgeries: A Comparative Study. AB - OBJECTIVE: To determine the differences in perioperative and postoperative outcomes between laparoscopic-assisted approach and open approach for appendicovesicostomy operations without concomitant procedures, among patients with prior abdominal surgeries. METHODS: A Research Ethics Board-approved retrospective cohort study was performed to review all laparoscopic-assisted vs open appendicovesicostomy procedures performed without concomitant procedure in patient with prior abdominal surgeries from January 2000 to January 2015 in our institution. We evaluated the baseline characteristics, perioperative and postoperative outcomes such as operative time, hospital stay, estimated blood loss, complications, and long-term continence. Fisher exact test and Mann-Whitney U test were performed to compare the 2 surgical groups. RESULTS: A total of 23 patients (11 open and 12 laparoscopic-assisted) were included. Baseline characteristics between the groups were not significantly different. Procedure time was comparable (Open median 289 [interquartile range {IQR} 230-335] vs laparoscopic-assisted median 231 [IQR 170.5-284]; P = .090). Significantly lower estimated blood loss and shorter hospital stay were noted among the laparoscopic assisted group (median 100 [IQR 75-200] vs 50 [IQR 25-100], P = .048; median 6 [IQR 5-8] vs 3.5 [IQR 3-5], P = .029; respectively). Complication rates of Clavien-Dindo class 3 in both groups were not significantly different (6 of 11 vs 8 of 12, P = .68). Stomal stenosis and continence rates were also not significantly different between the groups (36.4% vs 25%, P = .667 and 63.3% vs 83.3%, P = .371). CONCLUSION: Laparoscopic-assisted approach to create catheterizable stomas among patients with prior abdominal surgeries seems to be comparable to the open technique with the advantage of lower blood loss and shorter hospital stay.

PMID- 29572060 TI - A Survey of the Current Practice Patterns of Contralateral Testis Fixation in Unilateral Testicular Conditions. AB - OBJECTIVE: To query the current contralateral testis fixation (CTF) practice patterns among pediatric urologists in different clinical situations that could result in monorchism. METHODS: An online survey was sent to members of the Urology Section of the American Academy of Pediatrics. The survey included questions addressing CTF practice patterns in 14 clinical scenarios. Responses were anonymously submitted, blindly reviewed, and analyzed. RESULTS: Among 53 respondents, 62.3% had academic appointments and 73.6% had an exclusive pediatric urology practice. All participants agreed on CTF necessity in testicular torsion beyond the neonatal period. CTF was advocated by 84.9% in prenatal torsion, 96.2% in postnatal torsion, and 94.3% in delayed torsion presentation. Emergent intervention was favored by 64.4% in prenatal and 98% in postnatal torsion. Only 1 participant (1.9%) preferred CTF with a unilateral testicular tumor and 5 (9.4%) in trauma substantiating an orchiectomy. There was less consensus on CTF in torsed undescended testis (79.3% in prepubertal and 81.13% in postpubertal), testicular nubbin in a child (40.4%), palpable atrophic undescended testis (13.2%), and unilateral bell-clapper anomaly (47.2%). In situations other than torsion, lack of strong evidence was the commonest reason not to perform CTF. CONCLUSION: The majority of responding pediatric urologists currently performs CTF in neonatal torsion. Although there is a general consensus on CTF in testicular torsion outside the neonatal period, CTF remains controversial in other clinical situations, warranting further research. The decision for CTF should involve patients, parents, and treating physicians. PMID- 29572061 TI - Voxel-based lesion analysis of brain regions underlying reading and writing. AB - The neural basis of reading and writing has been a source of inquiry as well as controversy in the neuroscience literature. Reading has been associated with both left posterior ventral temporal zones (termed the "visual word form area") as well as more dorsal zones, primarily in left parietal cortex. Writing has also been associated with left parietal cortex, as well as left sensorimotor cortex and prefrontal regions. Typically, the neural basis of reading and writing are examined in separate studies and/or rely on single case studies exhibiting specific deficits. Functional neuroimaging studies of reading and writing typically identify a large number of activated regions but do not necessarily identify the core, critical hubs. Last, due to constraints on the functional imaging environment, many previous studies have been limited to measuring the brain activity associated with single-word reading and writing, rather than sentence-level processing. In the current study, the brain correlates of reading and writing at both the single- and sentence-level were studied in a large sample of 111 individuals with a history of chronic stroke using voxel-based lesion symptom mapping (VLSM). VLSM provides a whole-brain, voxel-by-voxel statistical analysis of the role of distinct regions in a particular behavior by comparing performance of individuals with and without a lesion at every voxel. Rather than comparing individual cases or small groups with particular behavioral dissociations in reading and writing, VLSM allowed us to analyze data from a large, well-characterized sample of stroke patients exhibiting a wide range of reading and writing impairments. The VLSM analyses revealed that reading was associated with a critical left inferior temporo-occipital focus, while writing was primarily associated with the left supramarginal gyrus. Separate VLSM analyses of single-word versus sentence-level reading showed that sentence-level reading was uniquely associated with anterior to mid-portions of the middle and superior temporal gyri. Both single-word and sentence-level writing overlapped to a great extent in the left supramarginal gyrus, but sentence-level writing was associated with additional underlying white matter pathways such as the internal capsule. These findings suggest that critical aspects of reading and writing processes diverge, with reading relying critically on the ventral visual recognition stream and writing relying on a dorsal visuo-spatial-motor stream. PMID- 29572062 TI - Better imagined: Neural correlates of the episodic simulation boost to prospective memory performance. AB - Episodic simulation is an adaptive process that can support goal-directed activity and planning success. We investigated the neural architecture associated with the episodic simulation improvement to the likelihood of carrying out future actions by isolating the brain regions associated with this facilitation in a prospective memory paradigm. Participants performed a lexical decision task by making word/non-word judgments, with rarely occurring prospective memory target words requiring a pre-specified manual response. Prior to scanning, participants were given exposure to two lists of prospective memory targets: animals and tools. In a fully counterbalanced design, participants generated a rhyme to one target list and imagined their subsequent encounter (episodic simulation) with target words on the other list. Replicating prior behavioral work, episodic simulation improved subsequent prospective memory performance. Brain activation was assessed in a multivariate partial least squares analysis. Relative to lexical decision blocks with no prospective memory demand, sustained prospective memory replicated prior observations of frontal polar activation. Critically, maintaining the intention to respond to simulated targets, over and above rhyme targets, engaged middle frontal and angular gyri, and medial parietal and prefrontal cortices. Transient activity associated with prospective memory target hits revealed activation for simulated targets in medial prefrontal cortex, posterior cingulate, lateral temporal lobe and inferior parietal lobule. In contrast, rhyme target hits engaged more left lateralized dorsolateral prefrontal cortex and anterior insula. Episodic simulation, thus effectively shifts executive control strategy and boosts task performance. These results are consistent with a growing body of evidence implicating executive control and default network region interactions in adaptive, goal-directed behavior. PMID- 29572063 TI - Agnosia for bird calls. AB - The cognitive organisation of nonverbal auditory knowledge remains poorly defined. Deficits of environmental sound as well as word and visual object knowledge are well-recognised in semantic dementia. However, it is unclear how auditory cognition breaks down in this disorder and how this relates to deficits in other knowledge modalities. We had the opportunity to study a patient with a typical syndrome of semantic dementia who had extensive premorbid knowledge of birds, allowing us to assess the impact of the disease on the processing of auditory in relation to visual and verbal attributes of this specific knowledge category. We designed a novel neuropsychological test to probe knowledge of particular avian characteristics (size, behaviour [migratory or nonmigratory], habitat [whether or not primarily water-dwelling]) in the nonverbal auditory, visual and verbal modalities, based on a uniform two-alternative-forced-choice procedure. The patient's performance was compared to healthy older individuals of similar birding experience. We further compared his performance on this test of bird knowledge with his knowledge of familiar human voices and faces. Relative to healthy birder controls, the patient showed marked deficits of bird call and bird name knowledge but relatively preserved knowledge of avian visual attributes and retained knowledge of human voices and faces. In both the auditory and visual modalities, his knowledge of the avian characteristics of size and behaviour was intact whereas his knowledge of the associated characteristic of habitat was deficient. This case provides further evidence that nonverbal auditory knowledge has a fractionated organisation that can be differentially targeted in semantic dementia. PMID- 29572064 TI - The Role of AMPK in Neuromuscular Biology and Disease. AB - AMP-activated protein kinase (AMPK) is a primary regulator of cellular metabolism. Recent studies have revealed that AMPK also mediates the maintenance and plasticity of alpha-motoneurons, the neuromuscular junction, and skeletal muscle. Furthermore, AMPK stimulation by either genetic, pharmacological, or physiological approaches elicits beneficial phenotypic remodeling in neuromuscular disorders (NMDs). Here, we review the role of AMPK as a governor of neuromuscular biology, and present evidence for AMPK as an effective molecular target for therapeutic pursuit in the context of the most prevalent NMDs, including Duchenne muscular dystrophy, spinal muscular atrophy, and myotonic dystrophy type 1. This information may be useful for engineering AMPK-targeted pharmacological- or lifestyle-based strategies to treat disorders of the neuromuscular system. PMID- 29572065 TI - Pericentromeric regions of homozygosity on the X chromosome: Another likely benign population variant. AB - PURPOSE: While chromosomal regions of homozygosity (ROH) may implicate genes in known recessive disorders, their correlation to disease pathogenicity remains unclear. ROH around the centromere of the X chromosome (pericentromeric, pROH) is regarded as benign, although this has not been empirically demonstrated. METHODS: We examined microarray results from 122 female individuals harboring ROH bordering the X centromere. RESULTS: Consecutive ROH was most frequently observed for regions Xp11.23 to Xp11.21 and Xq11.1 to Xq12, with an average total size of 16.5 Mb. X chromosome pROH was unlikely related to phenotype in 41% (50/122) of cases due to other explanations: likely pathogenic deletion/duplication (17%, 21/122), apparently unaffected female (7%, 8/122), other clinical explanation (7%, 9/122), or consanguinity (10%, 12/122). Of the remaining cases with pROH as the only finding, four genes were associated with recessive disorders that overlapped one or more clinical features reported in our probands (KDM5C, FGD1, ZC4H2, and LAS1L). X chromosome pROH observed in our cohort overlapped with previously reported regions. CONCLUSIONS: pROH on the X chromosome are commonly observed in both affected individuals with alternate causes of disease as well as in unaffected individuals, suggesting that X chromosome pROH has no clinically significant effect on phenotype. PMID- 29572066 TI - [Usefulness of local health reports to link the incidence rate of diarrhea with the quality of drinking water]. AB - In this study, we analyzed the reports of the health care center located in Vaqueros (Salta, Argentina) over an 8-month period. Moreover, we determined the concentration of Escherichia coli and Giardia spp. cysts in samples from four different drinking water sources. A statistical relationship between water quality and cases of diarrhea could not be found. However, using an odds ratio calculation, it was possible to determine that one of the studied drinking water systems acts as a protection factor in cases of diarrhea. The present work provides useful information for planning preventive measures by the local health system. PMID- 29572067 TI - Independent roles of CGRP in cardioprotection and hemodynamic regulation in ischemic postconditioning. AB - Calcitonin gene-related peptide (CGRP) may participate in ischemic post conditioning (IPost) attenuating myocardial ischemia/reperfusion injury. However, the molecular mechanism underlying the effect of CGRP is still elusive. In this study, we evaluated the difference in hemodynamics, infarct size and CGRP in myocardium and serum of rats after acute myocardial ischemia/reperfusion with and without IPost. A specific antagonist of CGRP receptor, CGRP8-37 was employed to testify the role of endogenous CGRP in IPost. The underlying mechanism was investigated by evaluation of the effect of CGRP on the changes in cytosolic reactive oxygen species, mitochondrial membrane potential and myocyte apoptosis induced by hypoxia/reoxygenation in cultured cardiomyocytes of neonatal rats. The results showed that IPost significantly upgraded CGRP in myocardium and serum with reduced infarct size, independent of the reductions in blood pressures observed in this study. The effects were significantly reversed by CGRP8-37, indicating an involvement of intrinsic CGRP. It was further demonstrated that CGRP effectively reversed the hypoxia/reoxygenation-induced reduction of mitochondrial membrane potential and attenuated the increases of cytosolic reactive oxygen species and cardiomyocyte apoptosis. The findings may demonstrate that CGRP mediates the cardioprotective and vasoactive effects of IPost. Homeostasis of cytosolic reactive oxygen species and mitochondrial membrane potential may be underlying the cardioprotective effect of CGRP. PMID- 29572069 TI - Two-detector number and brightness analysis reveals spatio-temporal oligomerization of proteins in living cells. AB - Number and brightness analysis (N&B) is a useful tool for the simultaneous visualization of protein oligomers and their localization, with single-molecule sensitivity. N&B determines particle brightness (fluorescence intensity per particle) and maps the spatial distribution of fluorescently labeled proteins by performing statistical analyses of the image series obtained using laser scanning microscopy. The brightness map reveals presence of the oligomers of the targeted protein and their distribution in living cells. However, even when corrections are applied, conventional N&B is affected by afterpulsing, shot noise, thermal noise, dead time, and overestimation of particle brightness when the concentration of the fluorescent particles changes during measurement. The drawbacks of conventional N&B can be circumvented by using two detectors, a novel approach that we henceforth call two-detector number and brightness analysis (TD N&B), and introducing a linear regression of fluorescence intensity. This statistically eliminates the effect of noise from the detectors, and ensures that the correct particle brightness is obtained. Our method was theoretically assessed by numerical simulations and experimentally validated using a dilution series of purified enhanced green fluorescent protein (EGFP), EGFP tandem oligomers in cell lysate, and EGFP tandem oligomers in living cells. Furthermore, this method was used to characterize the complex process of ligand-induced glucocorticoid receptor dimerization and their translocation to the cell nucleus in live cells. Our method can be applied to other oligomer-forming proteins in cell signaling, or to aggregations of proteins such as those that cause neurodegenerative diseases. PMID- 29572068 TI - Polygodial analog induces apoptosis in LNCaP prostate cancer cells. AB - Prostate cancer (PCa) is the second leading cause of death in American men. The chemotherapeutic treatment strategies are generally not effective and can lead to side effects. Hence, there is an urgent need to identify novel chemotherapeutic agents. The aim of this study was to synthesize and evaluate the therapeutic effects of a synthetic analog of polygodial (PG), a pungent constituent abundantly present in mountain pepper, water pepper and dorrigo pepper, on LNCaP PCa cell line and its anti-cancer mechanisms in a preclinical study. We evaluated the anti-cancer potential of the PG analog namely DRP-27 using various assays such as cell viability by MTT assay, anchorage independent growth by soft agar assay, reactive oxygen species generation by 2',7'-dichlorofluorescein probe based fluorescence assay, and apoptosis by Annexin-V and TUNEL assays respectively. Western blot analysis was performed to identify the molecular mechanism of DRP-27-induced cell death. Our results showed that DRP-27 significantly inhibited LNCaP cell proliferation in a dose-dependent manner at 48 h treatment in vitro. In addition, DRP-27 potently inhibited anchorage independent growth of these cells. Flow cytometry, Annexin-V and TUNEL assays confirmed that DRP-27 induces apoptosis in LNCaP cells. DRP-27 also induced the activation of intracellular reactive oxygen species. Western blot analysis revealed that DRP-27 downregulated the expression of survivin, while activating Bax and DNA damage marker pH2AX in LNCaP cells. In conclusion, our study suggests that DRP-27 might be an effective anti-cancer agent for PCa. PMID- 29572070 TI - ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Agents targeting lymphoid or myeloid cells surface antigens [II]: CD22, CD30, CD33, CD38, CD40, SLAMF-7 and CCR4). AB - BACKGROUND: The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. AIMS: To review, from an Infectious Diseases perspective, the safety profile of agents targeting CD22, CD30, CD33, CD38, CD40, SLAMF-7 and CCR4 and to suggest preventive recommendations. SOURCES: Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: The risk and spectrum of infections in patients receiving CD22-targeted agents (i.e. inotuzumab ozogamicin) are similar to those observed with anti-CD20 antibodies. Anti-Pneumocystis prophylaxis and monitoring for cytomegalovirus (CMV) infection is recommended for patients receiving CD30-targeted agents (brentuximab vedotin). Due to the scarcity of data, the risk posed by CD33 targeted agents (gemtuzumab ozogamicin) cannot be assessed. Patients receiving CD38-targeted agents (i.e. daratumumab) face an increased risk of varicella zoster virus (VZV) infection. Therapy with CD40-targeted agents (lucatumumab or dacetuzumab) is associated with opportunistic infections similar to those observed in hyper-IgM syndrome, and prevention strategies (including anti Pneumocystis prophylaxis and pre-emptive therapy for CMV infection) are warranted. SLAMF-7 (CD319)-targeted agents (elotuzumab) induce lymphopenia and increase the risk of infection (particularly due to VZV). The impact of CCR4 targeted agents (mogamulizumab) on infection susceptibility is difficult to distinguish from the effect of underlying diseases and concomitant therapies. However, anti-Pneumocystis and anti-herpesvirus prophylaxis and screening for chronic hepatitis B virus (HBV) infection are recommended. IMPLICATIONS: Specific management strategies should be put in place to reduce the risk and/or the severity of infectious complications associated to the reviewed agents. PMID- 29572071 TI - Long non-coding RNA HOTAIR and STAT3 synergistically regulate the cervical cancer cell migration and invasion. AB - Homeobox (HOX) transcript antisense RNA (HOTAIR) is a long intergenic non-coding RNA (lncRNA) that has been reported to be highly upregulated in several types of cancers. However, the role of HOTAIR in human cervical cancer is still unclear. We therefore investigated the expression and probable function of HOTAIR in cervical cancer cells. The expression of HOTAIR was examined in (HeLa, CaSki, ME 180, HT-3) and Human Cervical Epithelial Cells (HCerEpiC) by qRT-PCR. Transfection of si-NC, si-HOTAIR or si-STAT3 was carried out with the help of Lipofectamine 2000. The cell viability was assessed by CCK-8 assay. The cell migration and invasion was examined by wound healing and Boyden chamber assays. Protein expression was determined by western blotting. Our results showed that expression of HOTAIR was significantly upregulated in cervical cancer cells and inhibition of the expression of HOTAIR in HeLa cervical cancer cells resulted in suppression of cell proliferation, migration and invasion. Further, analysis of the promoter of HOTAIR, revealed that STAT3 could potentially regulate the activity of the HOTAIR in cervical cancer cells and inhibition of STAT3 had similar effects on the proliferation, migration and invasion of the cervical cancer cells as that of HOTAIR. Further, the suppression of STAT3 expression was associated with concomitant downregulation of IncRNA HOTAIR as indicated by the qRT-PCR. To unveil if STAT3 and HOTAIR have synergistic effects on the cell migration and invasion, si-STAT3 and si-HOTAIR were co-transformed into cervical HeLa cancer cells and it was observed that STAT3 and HOTAIR could synergistically inhibit the proliferation, migration and invasion of the cervical cancer cells. Taken together we conclude that HOTAIR and STAT3 synergistically regulate the proliferation, migration and invasion of cervical cancer cells. PMID- 29572072 TI - Effects of isopentyl ferulate on oxidative stress biomarkers and a possible GABAergic anxiolytic-like trait in Swiss mice. AB - This study aimed to evaluate the anxiolytic-like effect and the possible neuronal mechanism of action of isopentyl ferulate (IF). For this purpose, we used the marble burying test in Swiss albino mice. The biomarkers involved in oxidative stress were measured in the hippocampus homogenate of the test animals. In addition, the toxicity and antioxidant capacities were tested in Artemia salina and rat erythrocytes, respectively. The results suggest that, an acute administration of the IF at doses of 25, 50, 75 and 150 mg/kg (intraperitoneal, i.p.) significantly (p < 0.05) reduced the marble burying behavior of the animals as compared to the vehicle group, which demonstrates a calming effect of this chemical. It was observed that, the pre-treatment with flumazenil (2.5 mg/kg, i.p.), an antagonist of the gamma-amino butyrinc acid (GABAA) receptor, significantly reversed the marble burying behavioral activity in the animals treated with the IF 150 mg/kg dose. Moreover, the reduction in nitrite content and lipid peroxidation levels, while an increased in the reduced glutathione (GSH), glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT) activities were also observed their hippocampus. Although, IF (2.36-14.16 mM) did not show toxicity in A. salina but exhibited a prominent antioxidant capacity in hydrogen peroxide-induced oxidative damage in rat erythrocytes. In conclusion, IF exhibited an anxiety-like effect in mice along with a potent antioxidant capacity, and we suppose it may have neuroprotective effects possibly via GABAergic transmission pathway. PMID- 29572073 TI - ROS-independent toxicity of Fe3O4 nanoparticles to yeast cells: Involvement of mitochondrial dysfunction. AB - Fe3O4 nanoparticles, one kind of magnetic nanomaterials (NMs), are widely used in drug delivery, biological imaging, sensors, catalysts and pollution management. However, its toxicity to biological systems and related toxicity mechanisms remain to be explored. In this study, we investigate the effect of as-synthesized Fe3O4 nanoparticles on growth of Saccharomyces cerevisiae, an important model fungus. Growth inhibition assays showed that Fe3O4 nanoparticles remarkably inhibited yeast growth. Interestingly, this inhibitory effect was not attributed to the well-known plasma membrane damage, cell wall damage and ROS accumulation. Further investigations revealed that the nanoparticles strongly impaired mitochondrial functions, resulting in abnormal mitochondrial morphology, decreased mitochondrial membrane potential (MMP) and attenuated ATP production. Most importantly, the respiratory chain complex IV, rather than other respiratory chain complexes and ATP synthases, was found to be the main target of the nanoparticles. This study uncovers a novel ROS-independent toxicity mechanism of Fe3O4 nanoparticles to eukaryotic cells. PMID- 29572074 TI - Advanced biotherapy for the treatment of sulfur mustard poisoning. AB - CONTEXT: Sulfur mustard (SM), a bifunctional alkylating agent, can react with a variety of biochemical molecules (DNA, RNA, proteins and other cell components) to cause a series of serious health issues or even death. Although a plethora of research has been done, the pathogenesis of SM poisoning has yet to be fully understood due to its high complexity. As a consequence, a specific antidote has not yet been developed and the treatment of SM poisoning remains a medical challenge. In recent years, various biological products and cell transplantation in the treatment of SM poisoning offered a significant clinical treatment progress. By highlighting these and other research studies, we hereby summarize the progress in this field in an effort to provide useful information on the clinical treatment of SM poisoning. OBJECTIVE: This review summarizes the major advances of SM poisoning therapy by means of biological products (peptide and protein drugs, polysaccharides drugs, nucleic acid drugs, etc.), and cell transplantation (e.g., bone marrow, limbal stem cells, mesenchymal stem cells), as well as other relevant biotherapeutic approaches. METHOD: We searched the database PubMed for published domestic and international articles using web based resources for information on histological, immunochemical, ultrastructural, and treatment features of SM-induced manifestations in both animal models and human tissues. To this end, we applied keywords containing mustard gas, chemical warfare, SM, eye, lung and skin. RESULTS AND CONCLUSION: Our review provides a comprehensive understanding of the advances of available biotherapies in SM poisoning, and its potential for the treatment of SM-induced injuries. Potentially, our review will provide new insights for future research studies in this field. PMID- 29572075 TI - Key design and analysis principles for quality of life and patient-reported outcomes in clinical trials. AB - Advances in early detection and therapy have increased the number of prostate cancer survivors, leading to a greater emphasis on examining patient-reported outcomes (PROs). PROs augment clinical outcomes, providing a more comprehensive assessment of the patient experience, including symptoms and quality of life, that may impact the overall evaluation of new therapies. The successful incorporation of PROs into clinical trials requires adherence to key design and analysis principles. We present these principles and argue that adherence to these principles is vital to ensure valid interpretation of clinical trial findings, identify meaningful differences among investigational strategies, and better translate clinical trial results to diverse stakeholders. PMID- 29572076 TI - Disruptions in resting state functional connectivity in euthymic bipolar patients with insomnia symptoms. AB - Insomnia is prevalent in bipolar disorder (BD) even during periods of euthymic mood. We compared resting state brain activity and cognitive function between euthymic BD with and without insomnia, and secondarily to healthy individuals. BD patients with insomnia symptoms showed a significantly lower functional connectivity within the task-positive network, compared to those without insomnia. They also showed significantly slower cognitive processing speed. These two features of BD with insomnia appeared relatively independent of each other. Preliminary findings suggest that exploration of the mechanisms of sleep disturbance in BD could lead to improved understanding and treatment of inattention in BD. PMID- 29572077 TI - Experience using the "Shetty test" for initial foot and ankle fracture screening in the Emergency Department. AB - OBJECTIVE: The indiscriminate practice of radiographs for foot and ankle injuries is not justified and numerous studies have corroborated the usefulness of clinical screening tests such as the Ottawa Ankle Rules. The aim of our study is to clinically validate the so-called Shetty Test in our area. MATERIAL AND METHOD: A cross-sectional observational study by applying the Shetty test to patients seen in the Emergency Department. RESULTS: We enrolled 100 patients with an average age of 39.25 (16-86). The Shetty test was positive on 14 occasions. Subsequent radiography revealed a fracture in 10 cases: 4 were false positives. The test was negative in the remaining 86 patients and radiography confirmed the absence of fracture (with sensitivity of 100% and specificity of 95.56%, positive predictive value of 71.40%, and negative predictive value of 100%). CONCLUSIONS: The Shetty test is a valid clinical screening tool to decide whether simple radiography is indicated for foot and ankle injuries. It is a simple, quick and reproducible test. PMID- 29572078 TI - Osteochondromas of the Proximal Humerus. Diagnostic and Therapeutic Management. AB - OBJECTIVE: 1) To recall the epidemiology and signs of osteochondromas of the proximal humerus (OPH); 2) determine treatment indications; 3) and make recommendations for surgical treatment. METHODS: Retrospective, observational and longitudinal study of 20 solitary and 12 multiple osteochondromas of the proximal humerus. We analyzed the epidemiological, clinical and imaging characteristics and treatment results with an average time of follow-up of the operated cases of 45 months. RESULTS: Eleven (55%) males and 9(45%) females with an average age of 21 years presented solitary osteochondromas. Twelve (60%) cases were operated on at a mean age of 23 years because they were symptomatic or, in one case, malignancy was suspected. Two solitary osteochondromas could have spontaneously regressed. Multiple osteochondromas were found in 11(92%) males and one (8%) female of whom 3required surgery. There were no complications or recurrences. Functional outcome was excellent in all patients. DISCUSSION: Osteochondromas of the proximal humerus are relatively common, although most publications are case reports or short series. CONCLUSIONS: Osteochondromas of the proximal humerus do not differ from those in other locations. Symptomatic cases and those in which malignancy is suspected would be operated, the former preferably at the end of growth. The surgical treatment is summarized in planning the approach, using CT and/or MRI, extraperiosteal en bloc resection, and eventual bone reconstruction, ideally with allograft. PMID- 29572079 TI - Recent Advances and Future Directions in Postmastectomy Breast Reconstruction. AB - Postmastectomy breast reconstruction (PMBR) has evolved dramatically since it was first described by Vincent Czerny in 1895. The increasing numbers of mastectomy procedures and improved patient survival have placed an increasing emphasis on the aesthetic and psychosocial outcomes, prompting surgeons to develop more sophisticated methods to reconstruct the breast mound. Significant improvements have been made to existing implant and autologous methods of PMBR in recent decades in an effort to reduce donor site morbidity and complication rates and improve cosmesis. The limitations of contemporary methods of PMBR have directed research toward more novel techniques such as autologous fat grafting and adipose tissue engineering. The present review discusses recent advances in the evolution of contemporary approaches to breast reconstruction and the future directions of PMBR using adipose tissue engineering strategies. PMID- 29572080 TI - Restarting oral anticoagulant therapy after major bleeding in atrial fibrillation: A systematic review and meta-analysis. AB - BACKGROUND: Use of oral anticoagulant (OAC) therapy in atrial fibrillation (AF) is associated with an inherited risk of bleeding. Benefits and risks of OAC restarting after a major bleeding are still uncertain. We aimed to assess effectiveness and safety of restarting OAC in AF patients after a major bleeding event. METHODS: We performed a systematic review and meta-analysis of all studies reporting data about AF patients that sustained a major bleeding, reporting data on restarting or not restarting OAC therapy. RESULTS: A total of seven studies were included, involving 5685 patients. No significant difference was found in "any stroke" occurrence between OAC restarters and non-restarters (odds ratio [OR]: 0.75, 95% confidence interval [CI]: 0.37-1.51), with a significant 46% relative risk reduction (RRR) (p < 0.00001) for "any thromboembolism" in OAC restarters, with consistent results when the index bleeding event was an intracranial or gastrointestinal bleeding. A significantly higher risk of recurrent major bleeding was seen (OR: 1.85, 95% CI: 1.48-2.30), but no difference in risk for recurrence of index event. OAC restarters had a 10.8% absolute risk reduction for all-cause death (OR: 0.38, 95% CI: 0.24-0.60); p < 0.00001). Net clinical benefit (NCB) analysis demonstrated that restarting OAC therapy after a major bleeding was significantly associated with a clinical advantage (NCB: 0.11, 95% CI: 0.09-0.14; p < 0.001). CONCLUSIONS: Restarting OAC therapy after a major bleeding event in AF was associated with a positive clinical benefit when compared to non-restarting OAC, with a significant reduction in any thromboembolism and all-cause mortality. PMID- 29572081 TI - LDL-oxidation, serum uric acid, kidney function and pulse-wave velocity: Data from the Brisighella Heart Study cohort. AB - BACKGROUND: Serum uric acid (SUA) and oxidized LDL (oxLDL) may be associated with arterial aging. The aim of our study was to evaluate the relationship between SUA, oxLDL and arterial stiffness in subjects with normal renal function and in patients with mild or moderate renal impairment. METHODS: From the database of the 2012 Brisighella Heart Study, we compared age-matched adult, non-smoker subjects without cardiovascular disease and with normal renal function (n = 205), subjects with stage II chronic kidney disease (CKD) (n = 118) and subjects with stage III CKD (n = 94). All subjects underwent a determination of the LDL oxidative susceptibility, oxLDL levels, SUA and Pulse Wave Velocity (PWV). RESULTS: By univariate analysis, PWV correlated with a large number of clinical, haemodynamic and metabolic parameters, including estimated glomerular filtration rate (eGFR) in subjects with normal renal function and in those with stage II or III CKD. Stepwise multiple regression analyses showed that in the presence of normal renal function or stage II CKD, the main predictors of PWV were age, systolic blood pressure (SBP), ox-LDL, apolipoprotein B and SUA (p < 0.05), while in the presence of stage III CKD only age, SBP and apolipoprotein B remained significant (p < 0.05). CONCLUSION: Both ox-LDL and SUA independently predicts PWV only in subjects with normal or mildly reduced renal function, but not in the subjects with more compromised eGFR. This study confirms the complex relationship of SUA with cardiovascular and metabolic disease in the patient with established renal disease. PMID- 29572082 TI - Correlation of tricuspid regurgitation and new pacemaker implantation in patients undergoing transcatheter aortic valve implantation. AB - AIMS: Conduction abnormalities (CA), in particular complete atrioventricular block (CAVB), requiring permanent pacemaker (PPM) implantation, are frequent complications after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis (AS). However, the potential mechanisms are still incompletely understood. The objective of this retrospective study was to determine further predictors of CAVB after TAVI in patients without the known predictors. METHODS AND RESULTS: This study included patients without prior CA/PPM who underwent TAVI of a balloon-expandable valve (Sapien or Sapien XT or Sapien 3). Of 563 patients (81.2 +/- 6.9 years, 245 men [43.5%], logistic EuroSCORE 22.2 +/- 14.1%, STS PROM 5.9 [3.4-8.0]) who were treated by TAVI at our institution between July 2008 and January 2016, 61 (10.8%) developed a permanent CAVB after the procedure. In a multivariable logistic regression analysis moderate/severe tricuspid regurgitation (TR) (OR 2.05; 95% CI 1.18-3.55; p = 0.010) was identified as an independent predictor for new CAVB after TAVI. Moreover, patients with more pronounced TR presented with increased left and right ventricular overload (left ventricular (LV) end-diastolic diameter, LV end diastolic pressure), pulmonary pressures, NT-proBNP, and prevalence of mitral regurgitation >=II, whereas LV ejection fraction, TAPSE and cardiac output were decreased. CONCLUSIONS: PPM implantation is a frequent complication in patients undergoing TAVI. Increasing severity of TR seems to be a consequence of left and right ventricular overload caused by severe AS and is a significant predictor of new CAVB after TAVI. CONDENSED ABSTRACT: Conduction abnormalities (CA) requiring permanent pacemaker (PPM) implantation, are frequent complications after transcatheter aortic valve implantation (TAVI). This study included patients without prior CA/PPM who underwent TAVI. Of 563 patients 61 (10.8%) developed a permanent CAVB after the procedure. In a multivariable logistic regression analysis moderate/severe tricuspid regurgitation (TR) (OR 2.05; 95% CI 1.18-3.55; p = 0.010) was identified as an independent predictor for new CAVB. Therefore, in patients with moderate/severe TR utmost care should be taken to avoid procedural factors conducive to mechanical irritation of the conduction system, resulting in pacemaker dependency. PMID- 29572083 TI - Atrial fibrillation and prediction of mortality by conventional clinical score systems according to the setting of care. AB - BACKGROUND: Atrial fibrillation (AF) is associated with high morbidity and mortality, also among anticoagulated patients. Our aim was to evaluate the predictive role for long-term mortality of a series of risk stratification scores associated with cardiovascular or thromboembolic outcomes (CHADS2, CHA2DS2-VASc, ATRIA, TIMI-AF), and bleeding complications (HAS-BLED) in an unselected population of patients with AF. METHODS: Single center, observational, prospective registry of consecutive patients with AF, undergoing clinical/echocardiographic evaluation in a University Hospital, as either in patients or out-patients. We assessed the role of each single score as predictors of long-term survival according to clinical setting. RESULTS: We enrolled 1051 patients, mean age 72 +/- 12 years, who were followed for 797 +/- 298 days. All the tested scores showed a good performance in prediction of mortality, together with several clinical factors (older age, chronic heart failure, diabetes, renal impairment, previous transient ischemic attack, left ventricular ejection fraction). The values at C-statistics ranged between modest (0.608-0.684) of inpatients to good (0.708-0.751) in outpatients without any statistical difference between the scores, excepted a lower performance of HAD-BLED. CONCLUSIONS: Risk scores currently adopted for decision making on starting oral anticoagulation provide good prediction of long-term survival in unselected AF patients, especially in the outpatient setting. PMID- 29572084 TI - High intensity interval training versus moderate intensity continuous training on exercise capacity and quality of life in patients with heart failure with reduced ejection fraction: A systematic review and meta-analysis. AB - OBJECTIVE: The aim of this study was to investigate the effects of high intensity interval training (HIIT) versus moderate intensity continuous training (MICT) in heart failure patients with reduced ejection fraction (HFrEF). BACKGROUND: Despite the well-known positive effects of exercise in heart failure patients, the best mode of exercise is still under discussion. METHODS: We searched Pubmed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base, and SciELO (from the earliest date available to October 2017) for randomized controlled trials that evaluated the effects of HIIT versus MICT in HFrEF patients. Weighted mean differences (WMD) with 95% confidence interval (CI) were calculated, and heterogeneity was assessed using the I2 test. RESULTS: 13 studies met the study criteria, including 411 patients. Compared to MICT, HIIT resulted in improvement in Peak VO2 WMD (1.35 mL.kg-1.min-1 95% CI: 0.03 to 2.64 N = 411). HIIT resulted in no difference in VE/VCO2 slope WMD (-1.21 95% CI: -3.0 to 0.58 N = 135), and quality of life measured by Minnesota Living with Heart Failure questionnaire WMD (1.19 95% CI: -5.81 to 8.19 N = 79). Sub-group analyses comparing studies with and without isocaloric exercise training protocol also showed a nonsignificant difference in peak VO2 for participants in the HIIT group compared with MICT group. CONCLUSIONS: HIIT improves peak VO2 and should be considered as a component of care of HFrEF patients. However, its superiority versus MICT disappears when isocaloric protocols are compared. An important caveat is uncertainty and variation of actual training intensities compared to program targets. PMID- 29572085 TI - Ablation strategies for the management of symptomatic Brugada syndrome: A systematic review. AB - BACKGROUND: Ablation approaches have been described for the management of symptomatic ventricular arrhythmias in patients with Brugada syndrome, but this treatment is still considered experimental. OBJECTIVE: We aimed to perform a systematic review of the current evidence on the use of catheter ablation in Brugada syndrome. METHODS: MEDLINE, Embase, and Scopus were searched for articles describing the use of catheter ablation for ventricular arrhythmia management in Brugada syndrome. RESULTS: We included 11 case series and 11 case reports including a total of 233 patients. Ablation strategies included epicardial mapping with substrate modification (n = 180; 77.3%), endocardial-only mapping with substrate modification (n = 17; 7.3%), ventricular fibrillation (VF) triggering premature ventricular complex ablation (n = 5; 2.1%), and mixed approaches (n = 31; 13.3%). During a 2.5- to 78-month follow-up period, the success rates in preventing ventricular tachycardia or VF (VT/VF) were 96.7%, 70.6%, and 80% with epicardial, endocardial, and triggering premature ventricular complex ablation approaches, respectively. Among patients who underwent both epicardial and endocardial mapping, there was no identifiable endocardial substrate in 92.9% of cases. Elimination of type 1 Brugada-pattern electrocardiogram was attained in 98.3% and 34.8% of the epicardial and endocardial ablation groups, respectively. VT/VF occurred in 7 of 9 patients (77.8%) who had persistent or recurrent J-ST elevation and in none of the 24 patients with complete resolution during follow-up. Pharmacologic provocation augmented the abnormal area. CONCLUSION: Epicardial substrate modification appears to be more effective than endocardial-only approach in preventing VT/VF. Persistent or recurrent J-ST elevation appears to represent a marker of failure of ablation. Ablation seems to be an acceptable strategy for patients with Brugada syndrome and VT/VF. PMID- 29572086 TI - Influence of contact force on voltage mapping: A combined magnetic resonance imaging and electroanatomic mapping study in patients with tetralogy of Fallot. AB - BACKGROUND: Voltage criteria for ventricular mapping have been obtained from small series of patients and prioritizing high specificity. OBJECTIVE: The purpose of this study was to analyse the potential influence of contact force (CF) on voltage mapping and to define voltage cutoff values for right ventricular (RV) scar using the tetralogy of Fallot as a model of transmural RV scar and magnetic resonance imaging (MRI) as reference. METHODS: Fourteen patients (age 32.6 +/- 14.3 years; 5 female) with repaired tetralogy of Fallot underwent high resolution cardiac MRI (1.25 * 1.25 * 2.5 mm). Scar, defined as pixels with intensity >50% maximum, was mapped over the RV geometry and merged within the CARTO system to RV endocardial voltage maps acquired using a 3.5-mm ablation catheter with CF technology (SmartTouch, Biosense Webster). RESULTS: In total, 2446 points were analyzed, 915 within scars and 1531 in healthy tissue according to MRI. CF correlated to unipolar (rho = 0.186; P <.001) and bipolar voltage in healthy tissue (rho = 0.245; P <.001) and in scar tissue. Receiver operating characteristic curve analysis excluding points with very low CF (<5g) identified optimal voltage cutoffs of 5.19 mV for unipolar voltage and 1.76 mV for bipolar voltage, yielding sensitivity/specificity of 0.89/0.85 and 0.9/0.9, respectively. CONCLUSION: CF is an important factor to be taken into account for voltage mapping. If good CF is applied, unipolar and bipolar voltage cutoffs of 5.19 mV and 1.76 mV are optimal for identifying RV scar on endocardial mapping with the SmartTouch catheter. Data on the diagnostic accuracy of different voltage cutoff values are provided. PMID- 29572087 TI - Utility of dual-source computed tomography in cardiac resynchronization therapy DIRECT study. AB - BACKGROUND: Dual-source computed tomography (CT) can evaluate left ventricular (LV) dyssynchrony, myocardial scar, and coronary venous anatomy in patients undergoing cardiac resynchronization therapy (CRT). OBJECTIVE: We aimed to determine whether dual-source CT predicts clinical CRT outcomes and reduces intraprocedural time. METHODS: In this prospective study, 54 patients scheduled for CRT (mean age 63 +/- 11 years; 74% men) underwent preprocedural CT to assess their venous anatomy as well as CT-derived dyssynchrony metrics and myocardial scar. Based on 1:1 randomization, the implanting physician had preimplant knowledge of the venous anatomy in half the patients. In blinded analyses, we measured time to maximal wall thickness and inward wall motion to determine (1) CT global and segmental dyssynchrony and (2) concordance of lead location to regional LV mechanical contraction. End points were 6-month CRT response measured using heart failure clinical composite score and 2-year major adverse cardiac events (MACE). RESULTS: There were 72% CRT responders and 17% with MACE. Two wall motion dyssynchrony indices-global wall motion and opposing anteroseptal inferolateral wall motion-predicted MACE (P < .01). Lead location concordant to regions of maximal wall thickness was associated with less MACE (P < .01). No CT dyssynchrony metrics predicted 6-month CRT response (P = NS for all). Myocardial scar (43%), posterolateral wall scar (28%), and total scar burden did not predict outcomes (P = NS for all). Preknowledge of coronary venous anatomy by CT did not reduce implant or fluoroscopy time (P = NS for both). CONCLUSION: Two CT dyssynchrony metrics predicted 2-year MACE, and LV lead location concordant to regions of maximal wall thickness was associated with less MACE. Other CT factors had little utility in CRT. PMID- 29572088 TI - Predictive Factors for Death After Snake Envenomation in Myanmar. AB - INTRODUCTION: Factors predictive for death from snake envenomation vary between studies, possibly due to variation in host genetic factors and venom composition. This study aimed to evaluate predictive factors for death from snake envenomation in Myanmar. METHODS: A prospective study was performed among adult patients with snakebite admitted to tertiary hospitals in Yangon, Myanmar, from May 2015 to August 2016. Data including clinical variables and laboratory parameters, management, and outcomes were evaluated. Multivariate regression analysis was performed to evaluate factors predictive for death at the time of presentation to the hospital. RESULTS: Of the 246 patients with snake envenomation recruited into the study, 225 (92%) survived and 21 (8%) died during hospitalization. The snake species responsible for a bite was identified in 74 (30%) of the patients; the majority of bites were from Russell's vipers (63 patients, 85%). The independent factors predictive for death included 1) duration from bite to arrival at the hospital >1 h (odds ratio [OR]: 9.0, 95% confidence interval [CI]: 1.1-75.2; P=0.04); 2) white blood cell counts >20 *103 cells.MUL-1 (OR: 8.9, 95% CI: 2.3 33.7; P=0.001); and 3) the presence of capillary leakage (OR: 3.7, 95% CI: 1.2 11.2; P=0.02). A delay in antivenom administration >4 h increases risk of death (11/21 deaths). CONCLUSIONS: Patients who present with these independent predictive factors should be recognized and provided with early appropriate intervention to reduce the mortality rate among adults with snake envenomation in Myanmar. PMID- 29572089 TI - Magnetic resonance imaging is often misleading when used as an adjunct to ultrasound in the management of placenta accreta spectrum disorders. AB - BACKGROUND: Magnetic resonance imaging is reported to have good sensitivity and specificity in the diagnosis of placenta accreta spectrum disorders, and is often used as an adjunct to ultrasound. But the additional utility of obtaining magnetic resonance imaging to assist in the clinical management of patients with placenta accreta spectrum disorders, above and beyond the information provided by ultrasound, is unknown. OBJECTIVE: We aimed to determine whether magnetic resonance imaging provides data that may inform clinical management by changing the sonographic diagnosis of placenta accreta spectrum disorders. STUDY DESIGN: In all, 78 patients with sonographic evidence or clinical suspicion of placenta accreta spectrum underwent magnetic resonance imaging of the abdomen and pelvis in orthogonal planes through the uterus utilizing T1- and T2-weighted imaging sequences at the University of Utah and the University of Colorado from 1997 through 2017. The magnetic resonance imaging was interpreted by radiologists with expertise in diagnosis of placenta accreta spectrum who had knowledge of the sonographic interpretation and clinical risk factors for placenta accreta spectrum disorders. The primary outcome was a change in diagnosis from sonographic interpretation that could alter clinical management, which was defined a priori. Diagnostic accuracy was verified by surgical and histopathologic diagnosis at the time of delivery. RESULTS: A change in diagnosis that could potentially alter clinical management occurred in 28 (36%) cases. Magnetic resonance imaging correctly changed the diagnosis in 15 (19%), and correctly confirmed the diagnosis in 34 (44%), but resulted in an incorrect change in diagnosis in 13 (17%), and an incorrect confirmation of ultrasound diagnosis in 15 (21%). Magnetic resonance imaging was not more likely to change a diagnosis in the 24 cases of posterior and lateral placental location compared to anterior location (33% vs 37%, P = .84). Magnetic resonance imaging resulted in overdiagnosis in 23% and in underdiagnosis in 14% of all cases. When ultrasound suspected severe disease (percreta) in 14 cases, magnetic resonance imaging changed the diagnosis in only 2 cases. Lastly, the proportion of accurate diagnosis with magnetic resonance imaging did not improve over time (61-65%, P = .96 for trend) despite increasing volume and increasing numbers of changed diagnoses. CONCLUSION: Magnetic resonance imaging resulted in a change in diagnosis that could alter clinical management of placenta accreta spectrum disorders in more than one third of cases, but when changed, the diagnosis was often incorrect. Given its high cost and limited clinical value, magnetic resonance imaging should not be used routinely as an adjunct to ultrasound in the diagnosis of placenta accreta spectrum until evidence for utility is clearly demonstrated by more definitive prospective studies. PMID- 29572090 TI - Compatibility between weak gel and microorganisms in weak gel-assisted microbial enhanced oil recovery. AB - To investigate weak gel-assisted microbial flooding in Block Wang Long Zhuang in the Jiangsu Oilfield, the compatibility of weak gel and microbe was evaluated using laboratory experiments. Bacillus sp. W5 was isolated from the formation water in Block Wang Long Zhuang. The rate of oil degradation reached 178 mg/day, and the rate of viscosity reduction reached 75.3%. Strain W5 could produce lipopeptide with a yield of 1254 mg/L. Emulsified crude oil was dispersed in the microbial degradation system, and the average diameter of the emulsified oil particles was 18.54 MUm. Bacillus sp. W5 did not affect the rheological properties of the weak gel, and the presence of the weak gel did not significantly affect bacterial reproduction (as indicated by an unchanged microbial biomass), emulsification (surface tension is 35.56 mN/m and average oil particles size is 21.38 MUm), oil degradation (162 mg/day) and oil viscosity reduction (72.7%). Core-flooding experiments indicated oil recovery of 23.6% when both weak gel and Bacillus sp. W5 were injected into the system, 14.76% when only the weak gel was injected, and 9.78% with strain W5 was injected without the weak gel. The results demonstrate good compatibility between strains W5 and the weak gel and highlight the application potential of weak gel-assisted microbial flooding. PMID- 29572092 TI - Model for End-Stage Liver Disease Excluding INR (MELD-XI) score is associated with hemodynamic impairment and predicts mortality in critically ill patients. AB - PURPOSE: We aimed (i) to evaluate Model for End-stage Liver Disease excluding INR (MELD-XI) score for prediction of mortality in a cohort of critically ill patients and (ii) to investigate associations of MELD-XI with microcirculation and (iii) to evaluate microcirculation for prediction of mortality in high-risk patients, e.g., with high MELD-XI scores. METHODS: 308 patients were included in our retrospective analysis, a subgroup of the multicenter micro-SOAP-study. Microcirculation was evaluated by Sidestream Dark Field (SDF) imaging. Evaluation of associations with mortality was done by logistic regression analysis, an optimal cut-off was calculated by means of the Youden Index. We divided the cohort in two sub-groups based on their MELD-XI score at the optimal cut-off (12 score points). RESULTS: Patients with a MELD-XI > 12 points were of similar age (60 +/- 1 years vs 62 +/- 2 years; p = 0.32), but clinically sicker as mirrored by higher APACHE II scores (20 +/- 1 vs 16 +/- 1; p < 0.001). In the MELD-XI > 12 cohort in-hospital mortality was significantly higher compared to the MELD <= 12 group (48% vs 24%%; HR 2.98 95%CI 1.76-5.04; p = 0.003) and MELD-XI score was associated with mortality even after correction for relevant clinical confounders (HR 1.04 95%CI 1.01-1.07; p = 0.004) There were no associations between MELD-XI and parameters of microvascular perfusion. CONCLUSIONS: MELD-XI is associated with in-hospital mortality and constitutes a useful tool for risk stratification in intensive care medicine. Interestingly, there were no associations between MELD-XI and microcirculation. Possibly parameters of the microcirculation present an online tool of hemodynamic assessment while MELD-XI presents an assessment of already established organ failure.

PMID- 29572094 TI - Hepatic-targeted RNA interference provides robust and persistent knockdown of alpha-1 antitrypsin levels in ZZ patients. AB - BACKGROUND & AIMS: Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder causing pulmonary and liver disease. The PiZ mutation in AAT (SERPINA1) results in mis-folded AAT protein (Z-AAT) accumulating in hepatocytes, leading to fibrosis and cirrhosis. RNAi-based therapeutics silencing production of hepatic Z AAT might benefit patients with AATD-associated liver disease. This study evaluated an RNAi therapeutic to silence production of AAT. METHODS: Part A of this double-blind first-in-human study randomized 54 healthy volunteers (HVs) into single dose cohorts (two placebo: four active), receiving escalating doses of the investigational agent ARC-AAT from 0.38 to 8.0 mg/kg or placebo. Part B randomized 11 patients with PiZZ (homozygous for Z-AAT) genotype AATD, who received up to 4.0 mg/kg of ARC-AAT or placebo. Patients with baseline FibroScan(r) >11 kPa or forced expiratory volume in one second (FEV1) <60% were excluded. Assessments included safety, pharmacokinetics, and change in serum AAT concentrations. RESULTS: A total of 36 HVs received ARC-AAT and 18 received placebo (part A). Seven PiZZ individuals received ARC-AAT and four received placebo (part B). A dose response in serum AAT reduction was observed at doses >=4 mg/kg with similar relative reductions in PiZZ patients and HVs at 4 mg/kg and a maximum reduction of 76.1% (HVs) vs. 78.8% (PiZZ) at this dose. The time it took for serum AAT to return to baseline was similar for HV and PiZZ. There were no notable differences between HV and PiZZ safety parameters. The study was terminated early because of toxicity findings related to the delivery vehicle (ARC-EX1) seen in a non-human primate study. CONCLUSION: PiZZ patients and HVs responded similarly to ARC-AAT. Deep and durable knockdown of hepatic AAT production based on observed reduction in serum AAT concentrations was demonstrated. LAY SUMMARY: Accumulation of abnormal proteins in the livers of patients with alpha-1 antitrypsin deficiency may lead to decreased liver function and potentially liver failure. Therapeutics targeting the production of these abnormal proteins may be used to prevent or treat liver disease in patients with alpha-1 antitrypsin deficiency. CLINICAL TRIAL REGISTRATION NUMBER: NCT02363946. PMID- 29572091 TI - Effects on short term outcome of non-invasive ventilation use in the emergency department to treat patients with acute heart failure: A propensity score-based analysis of the EAHFE Registry. AB - OBJECTIVE: To assess the effects of non-invasive ventilation (NIV) in emergency department (ED) patients with acute heart failure (AHF) on short term outcomes. METHODS: Patients from the EAHFE Registry (a multicenter, observational, multipurpose, cohort-designed database including consecutive AHF patients in 41 Spanish EDs) were grouped based on NIV treatment (NIV+ and NIV-groups). Using propensity score (PS) methodology, we identified two subgroups of patients matched by 38 covariates and compared regarding 30-day survival (primary outcome). Interaction was investigated for age, sex, ischemic cardiomyopathy, chronic obstructive pulmonary disease, AHF precipitated by an acute coronary syndrome (ACS), AHF classified as hypertensive or acute pulmonary edema (APE), and systolic blood pressure (SBP). Secondary outcomes were intensive care unit (ICU) admission; mechanical ventilation; in-hospital, 3-day and 7-day mortality; and prolonged hospitalization (>7 days). RESULTS: Of 11,152 patients from the EAHFE (age (SD): 80 (10) years; 55.5% women), 718 (6.4%) were NIV+ and had a higher 30-day mortality (HR = 2.229; 95%CI = 1.861-2.670) (p < 0.001). PS matching provided 2 groups of 490 patients each with no significant differences in 30-day mortality (HR = 1.239; 95%CI = 0.905-1.696) (p = 0.182). Interaction analysis suggested a worse effect of NIV on elderly patients (>85 years, p < 0.001), AHF associated with ACS (p = 0.045), and SBP < 100 mmHg (p < 0.001). No significant differences were found in the secondary endpoints except for more prolonged hospitalizations in NIV+ patients (OR = 1.445; 95%CI = 1.122-1.862) (p = 0.004). CONCLUSION: The use of NIV to treat AHF in ED is not associated with improved mortality outcomes and should be cautious in old patients and those with ACS and hypotension. PMID- 29572095 TI - A simple diet- and chemical-induced murine NASH model with rapid progression of steatohepatitis, fibrosis and liver cancer. AB - BACKGROUND AND AIMS: Although the majority of patients with non-alcoholic fatty liver disease (NAFLD) have only steatosis without progression, a sizeable fraction develop non-alcoholic steatohepatitis (NASH), which can lead to cirrhosis and hepatocellular carcinoma (HCC). Many established diet-induced mouse models for NASH require 24-52 weeks, which makes testing for drug response costly and time consuming. METHODS: We have sought to establish a murine NASH model with rapid progression of extensive fibrosis and HCC by using a western diet (WD), which is high-fat, high-fructose and high-cholesterol, combined with low weekly dose of intraperitoneal carbon tetrachloride (CCl4), which serves as an accelerator. RESULTS: C57BL/6J mice were fed a normal chow diet +/- CCl4 or WD +/ CCl4 for 12 and 24 weeks. Addition of CCl4 exacerbated histological features of NASH, fibrosis, and tumor development induced by WD, which resulted in stage 3 fibrosis at 12 weeks and HCC development at 24 weeks. Furthermore, whole liver transcriptomic analysis indicated that dysregulated molecular pathways in WD/CCl4 mice and immunologic features were similar to those of human NASH. CONCLUSIONS: Our mouse NASH model exhibits rapid progression of advanced fibrosis and HCC, and mimics histological, immunological and transcriptomic features of human NASH, suggesting that it will be a useful experimental tool for preclinical drug testing. LAY SUMMARY: A carefully characterized model has been developed in mice that recapitulates the progressive stages of human fatty liver disease, from simple steatosis, to inflammation, fibrosis and cancer. The functional pathways of gene expression and immune abnormalities in this model closely resemble human disease. The ease and reproducibility of this model make it ideal to study disease pathogenesis and test new treatments. PMID- 29572097 TI - Hippocampal microvasculature changes in association with oxidative stress in Alzheimer's disease. AB - Vascular endothelial dysfunction is a primary phenotype of aging, and microvascular (MV) lesion is mainly associated with Alzheimer's disease (AD). Here we have studied the correlation of MV wall thickness and CA1 pyramidal neuronal pathology in autopsy-confirmed AD brains. Both hyaline (h-MV) and increased cell number (c-MV) associated MV wall thickening was found in age matched control (AC) hippocampus without significant change in Abeta level (Braak stages 0-III). AC neurons neighboring the h-MV showed lower levels of oxidative DNA/RNA damage and Abeta precursor protein (APP), while the neurons around c-MV showed higher oxidative DNA/RNA damage with increased APP expression. Neurons in AC hippocampus without MV wall thickening (thin wall) showed increased DNA/RNA damage and APP levels compared to AC cases with h-MV and c-MV walls. In the AD hippocampus neurons neighboring h-MV walls showed increased levels of Abeta and decreased number of dendritic spines (at Braak stages IV-VI). C-MV neighboring neurons in the AD cases showed higher levels of DNA/RNA damage with increased APP at stages II - III, followed by lower levels of oxidative DNA/RNA damage, decreased APP and increased Abeta levels with loss of dendritic spines at stages IV-VI. Prolonged treatment of primary human fetal hippocampal neurons with tert butyl hydroperoxide (TBHP) induced oxidative DNA damage with a sustained increase in APP. Abeta increased rapidly and then decreased overtime. Short-term TBHP treated neurons showed lower levels of superoxide (O2* -) without significant DNA damage. Short-term TBHP treatment induced a gradual decrease in APP but an increase in Abeta levels over time. In conclusion this study indicates that AD hippocampus at Braak stages II-III are characterized by strong oxidative DNA/RNA damage with increased APP in neurons associated with c-MV, while stages IV-VI are characterized by a slow increase in Abeta in neurons neighboring both h-MV and c MV. PMID- 29572098 TI - Ironing out the role of the cyclin-dependent kinase inhibitor, p21 in cancer: Novel iron chelating agents to target p21 expression and activity. AB - Iron (Fe) has become an important target for the development of anti-cancer therapeutics with a number of Fe chelators entering human clinical trials for advanced and resistant cancer. An important aspect of the activity of these compounds is their multiple molecular targets, including those that play roles in arresting the cell cycle, such as the cyclin-dependent kinase inhibitor, p21. At present, the exact mechanism by which Fe chelators regulate p21 expression remains unclear. However, recent studies indicate the ability of chelators to up regulate p21 at the mRNA level was dependent on the chelator and cell-type investigated. Analysis of the p21 promoter identified that the Sp1-3-binding site played a significant role in the activation of p21 transcription by Fe chelators. Furthermore, there was increased Sp1/ER-alpha and Sp1/c-Jun complex formation in melanoma cells, suggesting these complexes were involved in p21 promoter activation. Elucidating the mechanisms involved in the regulation of p21 expression in response to Fe chelator treatment in neoplastic cells will further clarify how these agents achieve their anti-tumor activity. It will also enhance our understanding of the complex roles p21 may play in neoplastic cells and lead to the development of more effective and specific anti-cancer therapies. PMID- 29572096 TI - SEXUAL DIMORPHISM IN SELENIUM METABOLISM AND SELENOPROTEINS. AB - Sexual dimorphism, the condition in which males and females in a species differ beyond the morphology of sex organs, delineates critical aspects of the biology of higher eukaryotes, including selenium metabolism. While sex differences in selenium biology have been described by several laboratories, delineation of the effects of sex in selenium function and regulation of selenoprotein expression is still in its infancy. This review encompasses the available information on sex dependent parameters of selenium metabolism, as well as the effects of selenium on sex hormones. Gaps in the current knowledge of selenium and sex are identified and discussed. PMID- 29572099 TI - A ten-year analysis of the reasons for death following ambulatory surgery: Nine closed claims declared to the SHAM insurance. AB - INTRODUCTION: The constant development of ambulatory surgery (AS) raises the problem of monitoring patients after discharge and the risk of death in the case of delays in the management of a serious complication. PATIENTS AND METHODS: The aim of this retrospective study was to describe the deaths observed within the 30 day period following AS declared to the SHAM insurance (Societe hospitaliere d'assurance mutuelle) over the last 10 years. RESULTS: During the study period 33,962 claims were surgery-related and 11 were for deaths after AS. Two of the death claims were excluded from our study because they occurred after the first month. The surgeries concerned were tonsilectomy (3), cataract (2), inguinal hernia (2), varicose vein stripping (1) and laparoscopy (1). Death occurred on average 5.4 days after the AS, in intensive care (3), during hospitalisation (2), with emergency medical services (1), in an emergency department (1) or at home (2). Anaesthesia was directly implicated in 3 cases: anaphylactic shock (Diamox), pneumoperitoneum (gastric swelling) and hemoperitoneum (mismanagement of anticoagulants). 1 case was due to a pulmonary embolism and 5 to a surgical cause. DISCUSSION-CONCLUSION: There was only one case where the complication was aggravated due to the delay of care provision and this was because of a lack of information on the complications requiring an emergency return (abdominal pain after laparoscopy). In all the other cases, death would also probably have occurred during conventional hospitalisation, either because it was unavoidable or because the patient was too far from the surgery.

PMID- 29572101 TI - Impact of connecting continuous renal replacement therapy to the extracorporeal membrane oxygenation circuit. AB - PURPOSE: Continuous veno-venous haemofiltration (CVVH) directly connected to extracorporeal membrane oxygenation (ECMO) may ensure better blood flow and allow prolonged circuit life. The objective of this study was to assess circuit life of CVVH connected to ECMO and to a dialysis catheter. MATERIALS AND METHODS: In this prospective observational study, patients receiving CVVH via ECMO were compared to time-matched patients receiving CVVH via a conventional dialysis catheter. CVVH circuit life and the safety and efficacy of the two CVVH procedures were analysed. Time to event was estimated using Kaplan-Meier analysis and compared using the log-rank test. RESULTS: Seventeen patients were included in each group, with 43 sessions in the ECMO group and 56 sessions in the DC group. Median CVVH circuit life was 48 [21-72] vs 20 [6-39] hours in the ECMO and DC groups, respectively (relative risk of termination of the session: 2.4, 95% CI [1.41 3.9], log rank P=0.0009). CVVH blood flow was higher in the ECMO group. Despite higher anticoagulant doses in the catheter group, the circuit clotting rate was lower in the ECMO group. Effluent volume was slightly higher in the ECMO group (39ml/kg/h [33-47] vs 34ml/kg/h [32-39]), but with no biological impact. CVVH via ECMO was well tolerated with no major drawbacks. CONCLUSIONS: In patients requiring ECMO, CVVH connected to ECMO instead of DC could be proposed as an alternative approach, allowing more stable blood flow and prolonged CVVH circuit life. PMID- 29572102 TI - Biochemical characterization of the Helicobacter pylori Cag Type 4 Secretion System protein CagN and its interaction partner CagM. AB - Highly virulent Helicobacter pylori strains contain the cag pathogenicity island (cagPAI). It codes for about 30 proteins forming a type IV secretion system (T4SS) which translocates the pro-inflammatory protein CagA into epithelial host cells. While CagA and various other Cag proteins have been extensively studied, several cagPAI proteins are poorly characterized or of unknown function. CagN (HP0538) is of unknown function but highly conserved in the cagPAI suggesting an important role. cagM (HP0537) is the first gene of the cagMN operon and its product is part of the CagT4SS core complex. Both proteins do not have detectable homologs in other type IV secretion systems. We have characterized the biochemical and structural properties of CagN and CagM and their interaction. We demonstrate by circular dichroism, Multi-Angle Light Scattering (MALS) and small angle X-ray scattering (SAXS) that CagN is a folded, predominantly monomeric protein with an elongated shape in solution. CagM is folded and forms predominantly dimers that are also elongated in solution. We found by various in vivo and in vitro methods that CagN and CagM directly interact with each other. CagM self-interacts stably with a low nanomolar KD and can form stable multimers. Finally, in vivo experiments show that deletion of CagM reduces the amounts of CagN and other outer CagPAI proteins in H. pylori cells. PMID- 29572103 TI - Event-related potential correlates of stimulus equivalence classes: A study of task order of the equivalence based priming probes with respect to the stimulus equivalence tests, and among the distinct trial types with each other. AB - This study investigates the influences of: 1) the task order of two stimulus equivalence classes (SEC) probes, and 2) the possible differences within the equivalence trial types. These factors were analyzed together on both behavioral and event-related potentials (ERP) data. Two groups of normal subjects participated in two successive sessions. In the first session, all participants were trained in the baseline relations among visual stimuli (pseudo-words). In the second session, one group performed the matching-to-sample (MTS) equivalence tests before the equivalence-relatedness-priming (EBRP) task, while the other group performed both tasks in reverse order. In the EBRP task related trial types included trained, symmetrical and equivalence relationships while the unrelated trial types included the same stimuli but without relationships. Event related potentials were recorded separately for related and unrelated conditions during the EBRP task. Results showed that response times to related trials were shorter than those to unrelated ones. At the electrophysiological level, two late waveforms were sensitive to the differences among the stimulus pairs of the EBRP task: Both waveforms were larger for the unrelated than the related conditions. Conversely, there were no main influences of the task order or of the trial types with each other. These results provide evidence that 1) the EBRP task exhibits priming effects among the SEC stimuli, 2) the behavioral and electrophysiological effects were similar regardless of whether the EBRP task was done before or after the MTS tests, and 3) there were no differences within the baseline and derived trial types in the EBRP task. PMID- 29572104 TI - Towards developing a model to study alcohol drinking and craving in female mice housed in automated cages. AB - It is about half a century ago when the so-called "Wise model" to study alcohol drinking behavior in rats was established. The model was based on voluntary intermittent access to increasing concentrations of alcohol. We aimed to establish a model of alcohol craving and used an extinction test on withdrawal days 1 and 10 to study motivation for alcohol. For this purpose, the alcohol drinking training was paired with light cues to establish conditioning. The extinction test was carried out without alcohol but in the presence of light cues and empty bottles. The outcome measures were number of visits, nosepokes, and licks in the conditioned corner where the number of nosepokes represents how much mice "want" alcohol and number of licks shows how much mice "like" alcohol. The number of nosepokes during withdrawal is a measure of craving. Late withdrawal craving was found when intermittent alcohol access was carried out in the automated cages. In this case, we observed a significant increase in the number of nosepokes on both withdrawal days 1 and 10 as compared to water control. The number of nosepokes in the withdrawal days did not correlate with alcohol dose, but number of nosepokes on withdrawal day 1 correlated with the number of nosepokes on the last training day. Although we did not observe incubation of alcohol craving after withdrawal, the craving was increased at the late time point. We conclude that we have established a new tool to study alcohol drinking behavior and craving in female mice. PMID- 29572105 TI - Behavioral and psychological symptoms of dementia (BPSD) and impaired cognition reflect unsuccessful neuronal compensation in the pre-plaque stage and serve as early markers for Alzheimer's disease in the APP23 mouse model. AB - Recent research on Alzheimer's disease (AD) focuses on processes prior to amyloid beta plaque deposition accounting for the progress of the disease. However, early mechanisms of AD are still poorly understood and predictors of the disease in the pre-plaque stage essential for initiating an early therapy are lacking. Behavioral and psychological symptoms of dementia (BPSD) and potentially impaired cognition may serve as predictors and early clinical diagnostic markers for AD. To investigate potential BPSD and cognitive impairments in association with neuronal cell development as such markers for AD in the pre-plaque stage, female APP23 mice at eight, 19 and 31 weeks of age and corresponding control animals were tested for BPSD (elevated zero maze; sucrose preference test), motor coordination (rotarod), spatial memory and reversal learning (Morris water maze) and hippocampal neurogenesis as a neuronal correlate for hippocampus-dependent behavior. To evaluate a potential therapeutic effect of physical, cognitive and social stimulation, animals were exposed to environmental enrichment (EE) for one, twelve or 24 weeks from five weeks of age. In APP23, decreased anxiety accompanied increased agitation from eight weeks of age. Impairment of spatial memory and learning flexibility prior to plaque deposition involved an insufficient use of spatial search strategies associated with an unsuccessful compensatory increase of neurogenesis. EE had an overall beneficial effect on behavior and neurogenesis and thus constitutes a therapeutic tool to slow disease progression. BPSD, cognition and associated impaired neurogenesis complement clinical diagnostic markers for pre-plaque AD and contribute to an early detection essential to halt disease progression. PMID- 29572106 TI - An integrated evidence-based targeting strategy for determining combinatorial bioactive ingredients of a compound herbal medicine Qishen Yiqi dripping pills. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Qishen Yiqi is a widely used Chinese herbal medicine formula with "qi invigorating and blood activating" property. Its dripping pill preparation (QSYQ) is a commercial herbal medicine approved by the China Food and Drug Administration (CFDA) in 2003 and is extensively used clinically to treat cardiovascular diseases, such as ischemic heart failure and angina pectoris, as well as for the secondary prevention of myocardial infarction. However, the bioactive ingredients of QSYQ remain unclear. As QSYQ is a compound herbal formula, it is of great importance to elucidate its pharmacologically active ingredients and underlying synergetic effects. AIM OF THE STUDY: This experimental study was conducted to comprehensively determine the combinatorial bioactive ingredients (CBIs) in QSYQ and to elucidate their potential synergetic effects. The established strategy may shed new light on how to rapidly determine CBIs in complex herbal formulas with holistic properties. MATERIALS AND METHODS: An integrated evidence-based targeting strategy was introduced and validated to determine CBIs in QSYQ. The strategy included the following steps: (1) Chemical ingredients in QSYQ were analyzed via UPLC-Q-TOF/MS in the negative and positive modes and were identified by comparison with standard compounds and previously reported data. Their potential therapeutic activities were predicted based on the ChEMBL database to preliminarily search for candidate bioactive ingredients, and their combination was defined as the CBIs. (2) The CBIs were directly trapped and prepared from QSYQ with a two dimensional chromatographic separation system, and the remaining part was defined as the rest ingredients (RIs). (3) As animal and cell models, left anterior descending coronary artery ligation (LAD)-induced heart failure in rats and hypoxia-induced cardiac myocyte injury in H9c2 cells were applied to compare the potency of QSYQ, CBIs and RIs. (4) The synergetic effects on cardiac myocyte protection of multiple ingredients in CBIs were examined in this cell model. RESULTS: (1) Forty-three ingredients in QSYQ were identified via UPLC-Q-TOF/MS. Based on evidence-based screening using the ChEMBL database, 24 ingredients were predicted to be bioactive ingredients, and their combination was considered the CBIs. (2) The CBIs and RIs were successfully prepared according to a two dimensional chromatographic system. The CBIs were directly trapped and knocked out from QSYQ by hydrophilic interaction liquid chromatography coupled with reverse-phase liquid chromatography. The remaining part was used as RIs. (3) The results from pharmacological evaluation revealed that CBIs and QSYQ, but not RIs, significantly prevented myocardium injury; improved the ejection fraction (EF) and fractional shortening (FS); decreased the release of cardiac enzymes, including CK, CK-MB, and LDH; alleviated mitochondrial dysfunction; and protected the cell nucleus number and mitochondrial mass. Furthermore, QSYQ and CBIs possessed similar potency. (4) In hypoxia-stimulated H9c2 cells, CBIs showed far greater potency regarding the protection of cardiac myocyte injury than the individual ingredients in QSYQ, exhibiting obvious synergetic effects. CONCLUSIONS: An integrated evidence-based targeting strategy was successfully established and validated to determine CBIs from QSYQ with excellent efficiency. Importantly, the holistic property of QSYQ was retained in the CBIs. Hence, this study may shed new light on how to rapidly reveal combinatorial bioactive ingredients from complex prescriptions and will be greatly helpful in the establishment of an appropriate approach to quality control for herbal medicines.

AB - PURPOSE: To compare the response of dry eye disease (DED) to treatment with topical steroid in patients with and without graft-vs-host disease (GVHD). DESIGN: Post hoc analysis of a double-masked, randomized clinical trial. METHODS: This single-center study included 42 patients with moderate-to-severe DED associated with (n = 21) or without (n = 21) chronic GVHD. In each group, patients received either loteprednol etabonate 0.5% ophthalmic suspension or artificial tears twice daily for 4 weeks. Clinical data, including Ocular Surface Disease Index (OSDI) questionnaire, corneal fluorescein staining (CFS), conjunctival lissamine green staining, tear break-up time (TBUT), and Schirmer test, were evaluated before and after treatment. RESULTS: There were no significant differences in signs and symptoms of DED between the groups at baseline. In non-GVHD patients receiving loteprednol treatment, the average OSDI score decreased by 34% from 49.5 +/- 5.9 to 32.6 +/- 4.8 (mean +/- standard error of the mean, P = .001) and the average CFS score decreased by 41% from 5.6 +/- 0.6 to 3.3 +/- 0.9 (P = .02). On the other hand, loteprednol treatment in GVHD patients resulted in minimal change in OSDI (59.2 +/- 6.7 to 61.1 +/- 7.1, 3% increase, P = .66) and CFS (5.5 +/- 0.5 to 5.3 +/- 1.1, 4% decrease, P = .85) scores. Treatment with artificial tears resulted in 22% decrease of OSDI (P = .10) and 32% decrease of CFS (P = .02) scores in non-GVHD patients, and had minimal effect in patients with GVHD. CONCLUSIONS: DED patients with ocular GVHD have a less favorable response to a low-dose topical steroid regimen compared with those without ocular GVHD even with similar baseline disease severity. PMID- 29572108 TI - Establishment of the 1st WHO International Standard for anti-EV71 serum (Human). AB - Enterovirus A71 (EV71) is the major causative agent of severe and fatal hand, foot and mouth disease. There is plenty of evidence that EV71 has circulated widely in the Western Pacific Region for the last twenty years. Vaccines against EV71 are already available or under development. A collaborative study to establish the 1st WHO International Standard for anti-EV71 serum (Human) was conducted to ensure that methods used to measure the serum neutralizing activity or antibody levels against EV71 are accurate, sensitive and reproducible. Two candidate samples as well as a third candidate reference containing low anti-EV71 antibody titre were produced from plasma samples donated by healthy individuals. All three serum samples exhibited good levels of neutralizing antibodies against a wide range of EV71 strains of various genotypes. The study showed that between laboratory variations in neutralization titres were significantly reduced when values were expressed relative to those of either of the two candidate sera. Sample 14/140 was established as the WHO 1st International Standard for anti-EV71 serum (human), 14/138 as its potential replacement and 13/238 as a WHO Reference Reagent, with assigned unitage of 1,000, 1090 and 300 International Units (IU) of anti-EV71 neutralizing antibodies per ampoule, respectively. PMID- 29572109 TI - N-Docosahexaenoylethanolamine: A neurotrophic and neuroprotective metabolite of docosahexaenoic acid. AB - N-Docosahexaenoylethanolamine (synaptamide) is an endocannabinoid-like metabolite endogenously synthesized from docosahexaenoic acid (DHA, 22:6n-3), the major omega-3 polyunsaturated fatty acid present in the brain. Although its biosynthetic mechanism has yet to be established, there is a closely linked relationship between the levels of synaptamide and its precursor DHA in the brain. Synaptamide at nanomolar concentrations promotes neurogenesis, neurite outgrowth and synaptogenesis in developing neurons. Synaptamide also attenuates the lipopolysaccharide-induced neuroinflammatory response and reduces the deleterious effects of ethanol on neurogenic differentiation of neural stem cells (NSCs). These actions are mediated by a specific target receptor of synaptamide GPR110 (ADGRF1), a G-protein coupled receptor that is highly expressed in NSCs and the brain during development. Synaptamide binding to GPR110 induces cAMP production and phosphorylation of protein kinase A (PKA) and the cAMP response element binding protein (CREB). This signaling pathway leads to the expression of neurogenic and synaptogenic genes and suppresses the expression of proinflammatory genes. The GPR110-dependent cellular effects of synaptamide are recapitulated in animal models, suggesting that synaptamide-derived mechanisms may have translational implications. The synaptamide bioactivity transmitted by newly deorphanized GPR110 provides a novel target for neurodevelopmental and neuroprotective control as well as new insight into mechanisms for DHA's beneficial effects on the central nervous system. PMID- 29572110 TI - Biological activities of non-enzymatic oxygenated metabolites of polyunsaturated fatty acids (NEO-PUFAs) derived from EPA and DHA: New anti-arrhythmic compounds? AB - omega3 Polyunsaturated fatty acids (omega3 PUFAs) have several biological properties including anti-arrhythmic effects. However, there are some evidences that it is not solely omega3 PUFAs per se that are biologically active but the non-enzymatic oxygenated metabolites of polyunsaturated fatty acids (NEO-PUFAs) like isoprostanes and neuroprostanes. Recent question arises how these molecules take part in physiological homeostasis, show biological bioactivities and anti inflammatory properties. Furthermore, they are involved in the circulations of childbirth, by inducing the closure of the ductus arteriosus. In addition, oxidative stress which can be beneficial for the heart in given environmental conditions such as the presence of omega3 PUFAs on the site of the stress and the signaling pathways involved are also explained in this review. PMID- 29572111 TI - Comparative Analysis of Flow Cytometry and RQ-PCR for the Detection of Minimal Residual Disease in Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia after Hematopoietic Stem Cell Transplantation. AB - The aim of this study was to examine the value of minimal residual disease (MRD) detection by multiparameter flow cytometry (MFC) and real-time quantitative PCR (RQ-PCR) at the early stage after hematopoietic stem cell transplantation for predicting relapse and leukemia-free survival (LFS) in Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+-ALL). Patients who maintained complete molecular remission (BCR-ABL <.01%) status at 1 and 3 months were associated with a lower relapse rate (P = .02 and <.001) and better LFS (P = .014 and .013) than were those without a complete molecular remission. Negative MFC at 1, 2, and 3 months was associated with a lower relapse rate (P = .01, .004, and .04, respectively) and better LFS (P = .044, <.0001, and .013, respectively). Multivariate analysis showed that MRD positivity identified by MFC or RQ-PCR at 3 months was an independent risk factor for relapse (hazard ratio [HR], 6.042 (95% confidence interval [CI], 2.283 to 15.988), P < .001), LFS (HR, 3.614 (95% CI, 1.610 to 8.111), P = .002), and overall survival (HR, 2.547, 95% CI, 1.008 to 6.443), P = .048). In summary, MRD detection by MFC and RQ-PCR detection of BCR ABL at the early stage were important predictors of outcome in patients with Ph+ ALL, and these tests played complementary roles in predicting prognosis. PMID- 29572112 TI - An automated Monte Carlo QC system for volumetric modulated arc therapy: Possibilities and challenges. AB - PURPOSE: To develop and implement an automated Monte Carlo (MC) system for patient specific VMAT quality control in a patient geometry that generates treatment planning system (TPS) compliant DICOM objects and includes a module for 3D analysis of dose deviations. Also, the aims were to recommend diagnose specific tolerance criteria and an evaluation procedure. METHODS: The EGSnrc code package formed the basis for development of the MC system. The workflow consists of a number of modules connected to a TPS by means of manual DICOM exports and imports which were executed sequentially without user interaction. DVH comparison was performed in the TPS. In addition, MC- and TPS dose distributions were analysed by applying the normalized dose difference (NDD) formalism. NDD failure maps and a pass rate for a certain threshold were obtained. 170 clinical plans (prostate, thorax, head-and-neck and gynecological) were selected for analysis. RESULTS: Agreement within 1.5% was found between clinical- and MC data for the mean dose to the target volumes and within 3% for parameters more sensitive to the shape of the DVH e.g. D98% PTV. Regarding the NDD analysis, tolerance criteria 2%/3 mm were established for prostate plans and 3%/3 mm for the rest of the cases. CONCLUSIONS: An automated MC system was developed and implemented. Evaluation procedure is recommended with NDD-analysis as a first step. For pass rate < 95%, the evaluation continues with comparison of DVH parameters. For deviations larger than 2%, a visual inspection of the clinical- and MC dose distributions is performed. PMID- 29572113 TI - Long-term results of hand-assisted laparoscopic gastrectomy for advanced Siewert type II and type III esophagogastric junction adenocarcinoma. AB - BACKGROUND: Hand-assisted laparoscopic surgery (HALS) combines laparoscopic surgery with the tactile feedback of a hand-assist device for complex laparoscopic operations. This study aimed to comparatively evaluate the long-term outcomes of patients who underwent HALS versus open surgery for the treatment of advanced Siewert type II and type III adenocarcinoma of the esophagogastric junction (AEG). METHODS: A retrospective analysis of 77 patients with advanced Siewert type II and IIIAEG between March 2010 and March 2011. Data concerning the basic characteristics of patients, pathological staging, early postoperative course, and long-term follow-up were collected and analyzed. RESULTS: HALS resulted in significantly lower mean blood loss and mean postoperative hospital stay in comparison to open surgery (P = 0.007 and 0.01, respectively). The mean number of resected lymph nodes was 23.22 +/- 9.36 in the HALS group, which was more than in the open surgery group (18.61 +/- 6.91, P = 0.015). The cumulative 5 year overall survival (OS) rate was 52.8% (95% CI 43.07-60.09) for all patients in the HALS group (78.6% for stage II patients and 36.4% for stage III patients). The 5-year OS rate was not significantly different between both groups. CONCLUSIONS: While achieving similar oncological outcomes to open surgery, the HALS approach resulted in reduced blood loss, shortened postoperative hospital stay, and the resection of more lymph nodes. This analysis suggests that HALS may serve as a less invasive and as successful alternative to open surgery for the treatment of advanced Siewert type II and type IIIAEG. PMID- 29572114 TI - Renal outcomes with sodium glucose cotransporter 2 (SGLT2) inhibitor, dapagliflozin, in obese insulin-resistant model. AB - A growing body of evidence indicates that obesity and insulin resistance contribute to the progression of renal disease. This study was performed to determine the effects of dapagliflozin, a novel sodium glucose cotransporter 2 (SGLT2) inhibitor, on renal and renal organic anion transporter 3 (Oat3) functions in high-fat diet fed rats, a model of obese insulin-resistance. Twenty four male Wistar rats were divided into two groups, and received either a normal diet (ND) (n = 6) or a high-fat diet (HFD) (n = 18) for 16 weeks. At week 17, the HFD-fed rats were subdivided into three subgroups (n = 6/subgroup) and received either a vehicle (HFD), dapagliflozin (HFDAP; 1.0 mg/kg/day) or metformin (HFMET; 30 mg/kg/day), by oral gavage for four weeks. Metabolic parameters, renal function, renal Oat3 function, renal oxidative stress, and renal morphology were determined. The results showed that obese insulin-resistant rats induced by HFD feeding had impaired renal function and renal Oat3 function together with increased renal oxidative injury. Dapagliflozin or metformin treatment decreased insulin resistance, hypercholesterolemia, creatinine clearance and renal oxidative stress leading to improved renal function. However, dapagliflozin treatment decreased blood pressure, serum creatinine, urinary microalbumin and increased glucose excretions, and showed a greater ability to ameliorate impaired renal insulin signaling and glomerular barrier damage than metformin. These data suggest that dapagliflozin had greater efficacy than metformin for attenuating renal dysfunction and improving renal Oat3 function, at least in part by reducing renal oxidative stress and modulating renal insulin signaling pathways, and hence ameliorating renal injury. PMID- 29572115 TI - Low galactosylation of IgG associates with higher risk for future diagnosis of rheumatoid arthritis during 10 years of follow-up. AB - Antibodies are known to have an important role in the development of rheumatoid arthritis (RA), one of the most prevalent chronic inflammatory diseases which primarily involves the joints. Most RA patients develop autoantibodies against immunoglobulin G (IgG) and changes in IgG glycosylation have been associated with RA. We undertook this study to determine whether altered IgG glycosylation precedes the disease diagnosis. We studied IgG glycosylation in RA in two prospective cohorts (N = 14,749) by measuring 28 IgG glycan traits in 179 subjects who developed RA within 10-years follow-up and 358 matched controls. Ultra-performance liquid chromatography method based on hydrophilic interactions (HILIC-UPLC) was used to analyse IgG glycans. Future RA diagnosis associated with traits related to lower galactosylation and sialylation of IgG when comparing the cases to the matched controls. In RA cases, these traits did not correlate with the time between being recruited to the study and being diagnosed with RA (median time 4.31 years). The difference in IgG glycosylation was relatively stable and present years before diagnosis. This indicates that long-acting factors affecting IgG glycome composition are among the underlying mechanisms of RA and that decreased galactosylation is a pre-existing risk factor involved in the disease development. PMID- 29572116 TI - Effect of irradiation-induced intercellular adhesion molecule-1 expression on natural killer cell-mediated cytotoxicity toward human cancer cells. AB - BACKGROUND AIMS: Irradiation enhances the adhesion between natural killer (NK) cells and target cells by up-regulating intercellular adhesion molecule-1 (ICAM 1) on target cells. Therefore, we investigated the effect of irradiation-induced ICAM-1 expression on human cancer cells on NK cell-mediated cytotoxicity. METHODS: Expression levels of ICAM-1 on the target cell surface before and after irradiation of six human cancer cell lines (HL60, SKBR-3, T47D, HCT-116, U937 and U251) were analyzed by flow cytometry. Ex vivo expansion of NK cells from human peripheral blood mononuclear cells was performed by co-culture with irradiated K562 cells. The related adhesion molecule lymphocyte function-associated antigen 1 (LFA-1) on NK cells was analyzed by flow cytometry. An enzyme-linked immunosorbent assay was used to detect interferon-gamma (IFN-gamma), and WST-8 assays were performed to check NK cell cytotoxicity. Finally, blocking assays were performed using monoclonal antibodies against ICAM-1 or LFA-1. RESULTS: LFA 1 expression increased on NK cells after expansion (P <0.001). The expression of ICAM-1 was significantly upregulated by irradiation after 24 h in various cell lines, including HL60 (P <0.001), SKBR-3 (P <0.001), T47D (P <0.001) and U937 (P <0.001), although the level of expression depended on the cell line. ICAM-1 expression was extremely low before and after irradiation in U251 cells. NK cell mediated cytotoxicity increased after irradiation of HL60 (P <0.001), SKBR-3 (P <0.001), T47D (P = 0.003), and U937 (P = 0.004) cells, in which ICAM-1 expression was significantly increased after irradiation. IFN-gamma production by NK cells in response to HL60 (P <0.001) and T47D (P = 0.011) cells significantly increased after irradiation. NK cell-mediated cytotoxicity against irradiated SKBR-3 (P <0.001) and irradiated T47D cells (P = 0.035) significantly decreased after blocking of ICAM-1. Blocking of LFA-1 on NK cells resulted in reduced cytotoxicity against irradiated HL60 (P <0.001) and irradiated SKBR-3 (P <0.001). CONCLUSIONS: Irradiation upregulates ICAM-1 expression on the surface of human cancer cells and enhances activated NK cell-mediated cytotoxicity. Therefore, irradiation combined with NK cell therapy may improve the antitumor effects of NK cells. PMID- 29572117 TI - Smad4/Fascin index is highly prognostic in patients with diffuse type EBV associated gastric cancer. AB - Gastric cancer is a heterogeneous disorder for which predicting clinical outcomes is challenging, although various biomarkers have been suggested. The Smad4 and Fascin proteins are known prognostic indicators of different types of malignancy. Smad4 primarily functions as a key regulator of tumor suppression, whereas Fascin exhibits oncogenic function by enhancing tumor infiltration. A combined marker based on these opposing roles may improve prognostic accuracy in gastric cancer. Smad4 and Fascin expression was assessed in tissue microarrays obtained from 285 primary gastric adenocarcinoma, 201 normal tissue, and 51 metastatic adenocarcinoma samples. A Smad4/Fascin index based on the relative expression of each protein was divided into low- and high-expression groups using receiver operating characteristic curves. We compared normal tissue, primary adenocarcinoma, and metastatic adenocarcinoma in Smad4 and Fascin expression and the differences in clinicopathological findings between low Smad4/Fascin and high Smad4/Fascin expression in gastric adenocarcinoma. High Smad4/Fascin expression was significantly associated with worse outcomes, such as old age, advanced T and N category, large tumor size, high histological grade, lymphatic and vascular invasion, and presence of Epstein-Barr virus (EBV) (all p < 0.05). Univariate and multivariate analyses revealed a significant relationship between disease-free or overall survival and Smad4/Fascin index in diffuse-type or EBV-associated gastric cancer (all p < 0.05). A dual marker system using Smad4 and Fascin may be a reliable indicator for predicting clinical outcomes in patients with diffuse-type or EBV-associated gastric cancer. PMID- 29572118 TI - Intradepartmental consultations in surgical pathology: Review of a standardized process and factors influencing consultation rates and practices in an academic and community hospital setting. AB - Intradepartmental consultations (ICs) are important for quality assurance (QA) and ensuring diagnostic accuracy in surgical pathology. Few studies have reviewed pathologist factors that influence IC rates. Our study reviews IC data and factors that influence both formal (written) and informal (verbal) consultation practices among pathologists in academic and community hospital settings. Formal IC records from the academic hospital were collected and academic and community pathologists were invited to complete a survey about their IC practices. All centers had a formalized process for documenting ICs; however, 92% of academic and 90% of community pathologists also requested informal IC. The top reasons for selecting a particular colleague for IC was perceived level of expertise; however, interpersonal relationships and office proximity had a greater impact on informal IC practice. Top reasons for requesting a formal IC were mandatory (subspecialty defined) consultation and uncertainty regarding pathological findings. Advice on wording was a common reason for informal IC. Written documentation of IC aids in QA and determination of IC metrics; however, informal, undocumented ICs still occur. Reasons for IC and choice of consulting pathologist are multifactorial, and identifying these can help target quality improvement initiatives. PMID- 29572119 TI - Bex1 attenuates neuronal apoptosis in rat intracerebral hemorrhage model. AB - Brain expressed x-linked gene 1 (Bex1) which is at high levels in several populations of central nervous system (CNS) neurons, belongs to a family of small proteins of unknown function, playing roles as adaptors or modulators of intracellular signaling pathways. But its distribution and function in CNS remains unclear. Neuronal apoptosis is the major pathogenesis in secondary brain injury of intracerebral hemorrhage (ICH). In this study, the roles of Bex1 were explored in the pathophysiology of ICH. Western blot, immunohistochemistry, and immunofluorescence showed that obvious up-regulation of Bex1 in neurons adjacent to the hematoma after ICH. Furthermore, the increase of Bex1 expression was accompanied by the enhanced expression of Bax and active caspase-3, and decreased expression of B-cell lymphoma 2 (Bcl-2) following ICH. The in vitro study using Bex1 siRNA transfection in hemin-exposed PC12 cells suggested that Bex1 exerted anti-apoptotic function. Therefore, Bex1 may play the neuronal anti-apoptosis role following ICH, implying a novel molecular target for the therapy of ICH. PMID- 29572120 TI - VEGFR-2 as a novel predictor of survival in gastric cancer: A systematic review and meta-analysis?. AB - BACKGROUND: Expression of VEGFRs may affect cancer prognosis. The aim of this work is to evaluate the prognostic significance of VEGFRs of patients with gastric cancer. METHODS: The databases PubMed, Embase, Web of Science, and Cochrane Library as well as ASCO and ESMO were searched systematically for articles reporting the prognostic significance of tissue VEGFRs in gastric cancer. The statistical analyses were carried out using Stata version 12.0. RESULTS: A total of 8 articles comprising 950 patients were eligible for meta analysis. The combined HR of studies evaluating total VEGFRs overexpression was 1.42 (95% CI 1.01-2.00, P = 0.044), suggesting that it had prognosis significance in overall survival of gastric cancer. Subgroup analysis showed that it was VEGFR 2 (HR 1.81, 95% CI 1.31-2.49, P < 0.001) but not VEGFR-3 (HR 0.91, 95% CI 0.45 1.82, P = 0.787) overexpression was associated with an increased risk of median overall survival (mOS) and it can be a potentially predictive biomarker for gastric cancer. CONCLUSIONS: VEGFR-2 overexpression is a promising negative prognosis predictor for patients with gastric cancer. The prognosis significance of VEGFR-3 still need further study. PMID- 29572121 TI - Prognostic significance of epithelial-mesenchymal transition phenotypes in upper urinary tract urothelial carcinoma. AB - Epithelial-mesenchymal transition (EMT) is a process which epithelial cells gain mesenchymal phenotype such as motility and invasiveness. We investigated the role of EMT in upper urinary tract urothelial carcinoma (UTUC). The patient cohort included 93 cases of UTUC treated with radical nephroureterectomy. Tissue microarrays were constructed from formalin-fixed paraffin-embedded tissue blocks. Immunohistochemical staining was performed for E-cadherin, vimentin, and smooth muscle actin to evaluate the EMT status. Interpretation criteria were defined for the staining results and EMT phenotypes were assigned as wild type, incomplete type (loss of E-cadherin and negative for vimentin), and complete type (loss of E cadherin and positive for vimentin). The loss of E-cadherin and vimentin expression was observed in 76 (81.7%) and 10 (10.8%) cases, respectively, yielding EMT phenotypes comprised of 17 cases (18.3%) of wild type, 66 cases (71.0%) of incomplete type, and 10 cases (10.8%) of complete types. In survival analyses, wild type showed statistically significant association with longer extra-bladder recurrence free survival (p < .001) and overall survival (p < .001). In multivariate analyses, complete type was an independent prognostic factor for extra-bladder recurrence free survival and overall survival. EMT phenotype based on the combination of EMT-related markers may provide a useful prognostic marker for UTUC patients. PMID- 29572122 TI - HPV infection and p16INK4A and TP53 expression in rare cancers of the uterine cervix. AB - Cervix cancer remains among most commonly diagnosed cancer in developing countries. Except squamous cell carcinoma and adenocarcinoma, the etiopathology and oncogenic mechanisms of rare cancers remain largely unknown. The study was performed to investigate the value of HPV infection and the expression of p16INK4A and TP53 in rare primitive cancers of the cervix. We conducted a retrospective study of rare primitive cancers of the cervix. Main clinicopathological features were reported. HPV infection was detected by in situ hybridization. Expression of p16INK4A and TP53 was analyzed by immunohistochemistry. Overall, seven cases were identified, including basaloid squamous cell carcinoma (BSCC, n = 2), small cell neuroendocrine carcinoma (SCNEC), granulocytic sarcoma without acute myeloid leukemia, leiomyosarcoma, primitive neuroectodermal tumor and botryoid-type embryonic rhabdomyosarcoma. The mean age of patients was 53.7 years. Four cancers were diagnosed at advanced stages. The prognosis was unfavorable and associated with patient death in five cases. HPV types 16/18 were detected in BSCCs and SCNEC. Strong and diffuse p16INK4A overexpression was described in the nucleus and the cytoplasm of all tumor cells of BSCCs and SCNEC. The remaining cancers exhibited only scattered and focal p16INK4A staining. Mutated TP53 protein was detected in BSCC (case 1) and GS. Rare cancers of the cervix are aggressive and associated with poor prognosis. In contrast to mesenchymal tumors, BSCCs and SCNEC are etiologically related to high-risk HPV infection and could be identified by block positive p16INK4A overexpression as common cancers of the cervix. TP53 mutations are not a negligible genetic event in rare cervical cancers. PMID- 29572123 TI - Clinical and electrocardiographic presentations of transient trifascicular block in three cats. AB - This report describes transient trifascicular block in three cats presented with lethargy and inappetence, and elevated cardiac troponin I concentrations. The electrocardiogram (ECG) of cat 1 showed a sinus rhythm with pronounced first degree atrioventricular (AV) block, right bundle branch block, and left anterior fascicular block. The ECG of cat 2 showed truncular left bundle branch block alternating with left anterior fascicular block coupled with prolonged PR intervals, second-degree heart block, and paroxysmal third-degree AV block. The ECG of cat 3 showed first-degree AV block with concomitant right bundle branch block. The diagnosis of trifascicular block was made when paroxysmal third-degree AV block was documented. All cats recovered with medical management within weeks. Each cat resumed a sinus rhythm. Elevated cardiac troponin I concentrations suggested myocarditis that improved. PMID- 29572124 TI - Short-interval and long-interval intracortical inhibition of TMS-evoked EEG potentials. AB - BACKGROUND: Inhibition in the human motor cortex can be probed by means of paired pulse transcranial magnetic stimulation (ppTMS) at interstimulus intervals of 2-3 ms (short-interval intracortical inhibition, SICI) or ~100 ms (long-interval intracortical inhibition, LICI). Conventionally, SICI and LICI are recorded as motor evoked potential (MEP) inhibition in the hand muscle. Pharmacological experiments indicate that they are mediated by GABAA and GABAB receptors, respectively. OBJECTIVE/HYPOTHESIS: SICI and LICI of TMS-evoked EEG potentials (TEPs) and their pharmacological properties have not been systematically studied. Here, we sought to examine SICI by ppTMS-evoked compared to single-pulse TMS evoked TEPs, to investigate its pharmacological manipulation and to compare SICI with our previous results on LICI. METHODS: PpTMS-EEG was applied to the left motor cortex in 16 healthy subjects in a randomized, double-blind placebo controlled crossover design, testing the effects of a single oral dose 20 mg of diazepam, a positive modulator at the GABAA receptor, vs. 50 mg of the GABAB receptor agonist baclofen on SICI of TEPs. RESULTS: We found significant SICI of the N100 and P180 TEPs prior to drug intake. Diazepam reduced SICI of the N100 TEP, while baclofen enhanced it. Compared to our previous ppTMS-EEG results on LICI, the SICI effects on TEPs, including their drug modulation, were largely analogous. CONCLUSIONS: Findings suggest a similar interaction of paired-pulse effects on TEPs irrespective of the interstimulus interval. Therefore, SICI and LICI as measured with TEPs cannot be directly derived from SICI and LICI measured with MEPs, but may offer novel insight into paired-pulse responses recorded directly from the brain rather than muscle. PMID- 29572125 TI - Hemoglobin, iron, vitamin B12, and folic acid deficiencies and hyperhomocysteinemia in Behcet's disease patients with atrophic glossitis. AB - BACKGROUND/PURPOSE: Behcet's disease (BD) patients should have recurrent aphthous stomatitis (RAS) but they may or may not have atrophic glossitis (AG). This study mainly assessed whether 30 AG-positive RAS/BD (AG+RAS/BD) patients had significantly higher frequencies of hemoglobin, iron, vitamin B12, and folic acid deficiencies and of hyperhomocysteinemia than 33 AG-negative RAS/BD (AG?RAS/BD) patients or 126 age- and sex-matched healthy control subjects. METHODS: The blood hemoglobin, iron, vitamin B12, folic acid, and homocysteine concentrations were measured and compared among 30 AG+RAS/BD patients, 33 AG?RAS/BD patients, and 126 healthy control subjects. RESULTS: We found that 43.3%, 33.3%, 13.3%, 6.7%, and 20.0% of 30 AG+RAS/BD patients and 18.2%, 36.4%, 0%, 6.1%, and 9.1% of 33 AG?RAS/BD patients had hemoglobin, iron, vitamin B12, and folic acid deficiencies and hyperhomocysteinemia, respectively. Moreover, 30 AG+RAS/BD patients had significantly higher frequencies of hemoglobin, iron, vitamin B12, and folic acid deficiencies and of hyperhomocysteinemia than healthy control subjects (all P values < 0.05), and had a higher frequency of hemoglobin deficiency (P = 0.058, marginal significance) and a significantly higher frequency of vitamin B12 deficiency (P = 0.046) than 33 AG?RAS/BD patients. In addition, the 33 AG?RAS/BD patients had significantly higher frequencies of hemoglobin and iron deficiencies than healthy control subjects (both P-values < 0.001). CONCLUSION: We conclude that AG+RAS/BD patients do have significantly higher frequencies of hemoglobin, iron, vitamin B12, and folic acid deficiencies and of hyperhomocysteinemia than healthy control subjects and have significantly higher frequencies of hemoglobin and vitamin B12 deficiencies than AG?RAS/BD patients. PMID- 29572126 TI - Bone health during endocrine therapy for cancer. AB - Preservation of bone health remains a long-term clinical challenge in patients with breast and prostate cancer. Osteoporosis, defined by a loss of bone mass and microarchitecture, often results in fragility fractures that are typically associated with a high socioeconomic burden. Endocrine therapy, a mainstay treatment in the management of patients with hormone-sensitive breast and prostate cancer in the adjuvant setting, commonly exerts adverse effects on the musculoskeletal system and is associated with an increased risk of osteoporosis and fractures. Adjuvant use of gonadotropin-releasing hormone analogues, which can also be used in metastatic disease, in combination with tamoxifen in premenopausal women, and aromatase inhibitors in postmenopausal women with hormone-sensitive breast cancer, causes rapid bone loss and fragility fractures. By contrast, selective oestrogen receptor modulators, such as tamoxifen, have bone-protective effects in postmenopausal women. In men with castration-sensitive prostate cancer, androgen deprivation is achieved with drugs that lower gonadotropin levels, and these drugs can be combined with androgen receptor antagonists. These therapies induce a high bone turnover with rapid bone loss that is reminiscent of the changes occurring in early menopause and result in an increased risk of fracture. In this Review, we describe how adjuvant endocrine therapies of breast and prostate cancer impair bone health and outline evidence from randomised controlled trials of strategies to reduce risk of fracture.

AB - Proteomics greatly benefited from the development of mass spectrometry. Over the last years, data-independent acquisitions increased in popularity in an effort to provide routine label free quantitative information. In this report, the performance of the Hi3 label free method was assessed based on the analysis of a plasma-derived protein mixture. The following parameters of the method (CVs) were determined: repeatability 13.8%, intermediate precision 27.6%, bias 32.3% and linearity observed over 3 orders of magnitude. Finally an accuracy of 42.5% corresponding to a confidence interval within 2 fold the expected protein abundance should be a good approximation of the method performance. PMID- 29572128 TI - A simple and reproducible protocol of glass surface silanization for TIRF microscopy imaging. AB - We describe a simple and reproducible protocol for the preparation of microscope glass slides for in vitro motility assays that use total internal reflection fluorescence microscopy. The developed method utilizes trimethylchlorosilane (TMCS) as a silanizing reagent, which in the presence of imidazole as a catalyst and under optimized conditions enables reproducible preparation of high-quality hydrophobic glass surfaces. This method presents a simplification and improvement in reproducibility over the commonly applied protocol utilizing dichlorodimethylsilane (DDS) as a silanizing agent. We demonstrate the applicability of the new method by performing the analysis of the interactions of a molecular motor, kinesin-1 with microtubules.

AB - OBJECTIVE: Physiotherapists typically prescribe exercise therapy for people with osteoarthritis (OA) via face-to-face consultations. This study aimed to explore peoples' perceptions of exercise therapy delivered by physiotherapists via telephone for their knee OA. DESIGN: A qualitative study (based on interpretivist methodology) embedded within a randomised controlled trial. Semi-structured individual interviews were conducted with 20 people with knee OA who had received exercise advice and support from one of eight physiotherapists via telephone over 6 months. Interviews were audio recorded, transcribed verbatim and thematically analysed. RESULTS: Although people with OA were initially sceptical about receiving exercise therapy via telephone, they described mostly positive experiences, valuing the convenience and accessibility. However, some desired visual contact with the physiotherapist and suggested including video conferencing calls or an initial in-person clinic visit. Participants valued the sense of undivided focus and attention they received from the physiotherapist and believed that they were able to communicate effectively via telephone. Participants felt confident performing their exercise program without supervision and described benefits including increased muscular strength, improved pain, and ability to perform tasks that they had not been previously able to. CONCLUSIONS: People with knee OA held mostly positive perceptions about receiving exercise therapy from a physiotherapist via telephone, suggesting that such a service is broadly acceptable to consumers. Such services were generally not viewed as a substitute for face-to-face physiotherapy care, but rather as a new option that could increase accessibility of physiotherapy services, particularly for follow up consultations.

AB - OBJECTIVE: There is limited information regarding changes in bone architecture following anterior cruciate ligament (ACL) injury. The objective of this study was to evaluate differences in tibial fractal signature in the medial and lateral compartments following ACL injury and describe how these values change following ACL-reconstruction and return to activity. DESIGN: This was a prospective cohort study with a nested case-control analysis. ACL-injured subjects and matched controls were evaluated at pre-surgical baseline and post ACL reconstruction follow-up at a mean of 46 months. Serial Fractal Dimensions (FD) of tibial subchondral bone architecture were calculated in medial and lateral regions of interest in the horizontal and vertical dimensions. RESULTS: In the medial and lateral compartments, there were significant differences in the vertical FD signature for ACL-injured subjects at final follow-up, when compared to the contralateral healthy tibia (medial P < 0.0001; lateral P < 0.0001) and the control group (medial P = 0.01; lateral P < 0.0001). Similarly, in the lateral compartment, there were significant differences in the horizontal FD profile for ACL-injured subjects at final follow-up, when compared to the contralateral healthy tibia (P = 0.003) and the controls (P < 0.0001). There were no significant side-to-side differences in FDs among healthy control subjects in the medial or lateral compartments at baseline or final follow-up. CONCLUSION: At 46 month follow-up, FD profiles are significantly different, and show an overall lower FD signature, for ACL-injured knees when compared to the contralateral healthy knee and uninjured controls. Additionally, this study provided the first side-to-side symmetry data of medial and lateral FD values in healthy controls. PMID- 29572131 TI - Oxidative stress-mediated influence of plasma DPP4 activity to BDNF ratio on mild cognitive impairment in elderly type 2 diabetic patients: results from the GDMD study in China. AB - OBJECTIVE: Increased dipeptidyl peptidase-4 (DPP4) activity and reduced brain derived neurotrophic factor (BDNF) in peripheral circulation are both associated with a high risk of mild cognitive impairment (MCI) in the elderly. Hence, we aimed to investigate the association between plasma DPP4 activity to BDNF ratio (DBR) and MCI in elderly patients with type 2 diabetes. DESIGN AND METHODS: We measured plasma DPP4 activity, BDNF levels, oxidative stress parameters, inflammatory markers and calculated DBR in 1833 elderly type 2 diabetic patients aged 60 years or older. MCI was diagnosed according to the National Institute on Aging-Alzheimer's Association workgroups criteria. Further, mediation analysis was performed to estimate the mediator role of oxidative stress on the relationship between DPP4 activity and BDNF. RESULTS: DPP4 activity was negatively associated with BDNF (r = -0.408, P < 0.001). Oxidative stress, particularly in male participants, acted as a partial mediator in the relationship between DPP4 activity and BDNF. Participants in the highest quartile of DBR had higher nitrotyrosine, 8-isoPGF2a, interleukin-6, C-reactive protein and lower Montreal Cognitive Assessment score compared with those in the lowest quartile. The odds ratio (5.15, 95% CI 3.64-7.30) for MCI in the highest DBR quartile was significantly higher than in the lowest quartile. The risk for MCI increased with higher levels of DPP4 activity and lower levels of BDNF. CONCLUSIONS: Oxidative stress partially mediates the inverse relationship between DPP4 and BDNF. Our data provide evidence for a strong link between DBR and MCI, suggesting DBR to be a new biomarker for MCI in type 2 diabetic patients. PMID- 29572132 TI - Sleep biology updates: Hemodynamic and autonomic control in sleep disorders. AB - Sleep disorders like obstructive sleep apnea syndrome, periodic limb movements in sleep syndrome, insomnia and narcolepsy-cataplexy are all associated with an increased risk of cardiovascular diseases. These disorders share an impaired autonomic nervous system regulation that leads to increased cardiovascular sympathetic tone. This increased cardiovascular sympathetic tone is, in turn, likely to play a major role in the increased risk of cardiovascular disease. Different stimuli, such as intermittent hypoxia, sleep fragmentation, decrease in sleep duration, increased respiratory effort, and transient hypercapnia may all initiate the pathophysiological cascade leading to sympathetic overactivity and some or all of these are encountered in these different sleep disorders. In this manuscript, we outline the different pathways leading to sympathetic over activity in different sleep conditions. This augmented sympathetic tone is likely to play an important role in the development of cardiovascular disease in patients with sleep disorders, and it is further hypothesized to that sympathoexcitation contributes to the metabolic dysregulation associated with these sleep disorders. PMID- 29572134 TI - Replacement of the Distorted Dentition of the Cone-Beam Computed Tomography Scans for Orthognathic Surgery Planning. AB - PURPOSE: Cone-beam computed tomography (CBCT) does not record dental morphology accurately because of the scattering produced by metallic restorations and the reported magnification of the dentition. The aim of this study was the development and evaluation of a new method for the replacement of the distorted dentition of CBCT scans with a 3-dimensional (3D) dental image captured by a digital intraoral camera. MATERIALS AND METHODS: Six dried skulls with orthodontic brackets fixed on the teeth were used in this study. Three intraoral markers made of dental stone were constructed and attached to orthodontic brackets. The skulls were scanned by CBCT and the occlusal surfaces were captured using the TRIOS 3D intraoral scanner. The digital intraoral scan (IOS) was fused into the CBCT models. This produced a new composite digital model of the skull and the dentition. The skulls were scanned again using the commercially accurate Faro laser arm to produce the 3D model the skull and teeth gold standard for the assessment of the accuracy of the developed method. This was assessed by measuring the distance between the occlusal surfaces of the new composite model and the gold standard 3D laser produced model. RESULTS: The results showed the errors related to the superimposition of the intraoral image on the CBCT to replace the distorted dentition were 0.11 to 0.20 mm. CONCLUSION: The results of this novel method suggest that the dentition on the CBCT scan can be accurately replaced with the digital IOS image captured by an intraoral scanner to create a composite model that will improve the accuracy of digital orthognathic surgical planning and the fabrication of the guiding occlusal wafer. PMID- 29572133 TI - Effect of Obesity or Metabolic Syndrome and Diabetes on Osseointegration of Dental Implants in a Miniature Swine Model: A Pilot Study. AB - PURPOSE: The increasing prevalence of obesity or metabolic syndrome (O/MS) and type 2 diabetes mellitus (DM) remains a global health concern. Clinically relevant and practical translational models mimicking human characteristics of these conditions are lacking. This study aimed to demonstrate proof of concept of the induction of stable O/MS and type 2 DM in a Gottingen minipig model and validate both of these disease-adjusted Gottingen minipig models as impaired healing models for the testing of dental implants. MATERIALS AND METHODS: Nine minipigs were split into 3 groups-control (normal diet), obese (cafeteria diet), and diabetic (cafeteria diet plus low-dosage streptozotocin)-followed by placement of dental implants. Inflammatory markers including tumor necrosis factor alpha, C-reactive protein, and cortisol were recorded for each study group. Removal torque was measured, and histomorphometric analysis (bone-to implant contact and bone area fraction occupancy) was performed. RESULTS: O/MS pigs showed, on average, a 2-fold increase in plasma C-reactive protein (P < .05) and cortisol (P < .09) concentrations compared with controls; DM pigs showed, on average approximately, a 40-fold increase in plasma tumor necrosis factor alpha levels (P < .05) and a 2-fold increase in cortisol concentrations (P < .05) compared with controls. The impact of O/MS and DM on implants was determined. The torque to interface failure was highest in the control group (200 N-cm) and significantly lower in the O/MS (90 N-cm) and DM (60 N-cm) groups (P < .01). Bone formation around implants was significantly greater in the control group than in the O/MS and DM groups (P < .02). CONCLUSIONS: Both O/MS and DM minipigs express a human-like disease phenotype, and both presented bone-healing impairment around dental implants. Our finding of no significant difference between type 2 DM and O/MS in bone formation around implants provides evidence that further investigation of the impact of O/MS is warranted. PMID- 29572135 TI - First characterization of an anti-lipopolysaccharide factor (ALF) from hydrothermal vent shrimp: Insights into the immune function of deep-sea crustacean ALF. AB - Anti-lipopolysaccharide factor (ALF) is a type of antimicrobial peptides (AMPs) with a vital role in antimicrobial defense. Although a large amount of ALFs have been identified from neritic and fresh water crustacean species, no functional investigation of ALFs from deep-sea animals have been documented. In the present study, we characterized the immune function of an ALF molecule (named RspALF1) from the shrimp Rimicaris sp. residing in the deep-sea hydrothermal vent in Desmos, Manus Basin. RspALF1 shares 51.5%-62.4% overall sequence identities with known shrimp ALFs and contains the conserved LPS binding domain (LBD). Both recombinant RspALF1 (rRspALF1) and the LBD-derived peptide (ALF1P1) bound to the cell wall components of Gram-negative and Gram-positive bacteria and killed a wide range of bacteria, especially those from deep-sea hydrothermal field, by damaging bacterial cellular structures. The bactericidal activities of rRspALF1 and ALF1P1 were optimal and stably maintained from 4 degrees C to 37 degrees C, which is comparable to the ambient temperature range of the habitat of Rimicaris sp. In addition to bacteria, rRspALF1 and ALF1P1 also exhibited anti-fungal activity. rRspALF1 and ALF1P1 exhibited high killing efficiencies, which, in terms of MIC values, were ranged between 0.25 MUM and 4 MUM for bacteria and 4 MUM-8 MUM for fungi. When introduced in vivo, both rRspALF1 and ALF1P1 effectively inhibited bacterial infection in shrimp and reduced the dissemination of bacterial and viral pathogens in fish. Together, these results provide the first insight into the biological property of deep-sea ALF and indicate that RspALF1 very likely plays a significant role in immune defense by functioning as a highly effective antimicrobial with a broad target range. PMID- 29572136 TI - Addressing Racial Disparity in Colorectal Cancer Screening With CT Colonography: Experience in an African-American Cohort. AB - BACKGROUND: Incidence and mortality from colorectal cancer (CRC) are higher among African Americans where CRC screening rates lag behind non-Hispanic whites. The purpose of this investigation was to evaluate CT colonography (CTC) performance and outcome measures in an African-American cohort. MATERIALS AND METHODS: This study is an institutional review board-approved and Health Insurance Portability and Accountability Act-compliant study. Retrospective evaluation of the African American cohort from the Atlanta VA Medical Center (Decatur, Georgia) CTC screening program. Colonoscopy referral rates and histologic diagnoses were evaluated. RESULTS: CTC studies (n = 2490; mean age, 59.5 years [range, 50-80 years]; 85.5% male; all African American) were performed between 2007 and 2016. The per-patient CTC positive rate was 9.8% for polyps from 6 to 9 mm, 5.4% for polyps from 10 to 29 mm, and 1.3% for masses >= 30 mm. Based on CTC findings and patient preference, 13.9% of patients were referred to optical colonoscopy and 2.9% were referred to CTC follow-up. Of patients recommended to undergo colonoscopy, 80.6% completed the procedure and colonic pathology was confirmed in 83.2% thereof. Histologic diagnoses were 221 tubular adenomas (161 6-9 mm; 60 >= 10 mm), 59 tubulovillous adenomas/villous adenomas (14 6-9 mm; 45 >= 10 mm), 34 hyperplastic-serrated polyps (27 6-9 mm; 7 >= 10 mm), 18 adenocarcinomas (all >= 10 mm), and 11 adenomas with high-grade dysplasia (all >= 10 mm). The per-patient positivity rate for patients who had optical colonoscopy (n = 279) was 71.3% for adenoma, 9.7% for hyperplastic polyp, and 6.1% for adenocarcinoma. CONCLUSIONS: CTC is an effective screening modality for African-American adults and could potentially improve rates of colorectal screening in this underserved population. PMID- 29572138 TI - Preparation, characterization, digestibility and antioxidant activity of quercetin grafted Cynanchum auriculatum starch. AB - In this study, a novel method was developed to conjugate quercetin with Cynanchum auriculatum starch. Quercetin was first succinylized and then grafted onto C. auriculatum starch through a N,N'-carbonyldiimidazole mediated reaction. The obtained water soluble quercetin grafted starch (quercetin-g-starch) was characterized by several instrumental methods. UV-vis spectrum of quercetin-g starch aqueous solution exhibited two absorption bands at around 300 and 430nm. Fourier-transform infrared spectrum of quercetin-g-starch showed characteristic bands at 1731 and 1568cm-1, assigning to CO stretching of esterified carboxyl group and CC stretching of aromatic ring, respectively. Proton nuclear magnetic resonance spectrum of quercetin-g-starch showed partial proton signals of starch (3.30-5.47ppm) and quercetin (6.19-7.68ppm). All above results suggested quercetin was successfully grafted onto C. auriculatum starch. Besides, quercetin g-starch particles were irregular in shape and were in an amorphous state. Notably, the thermal stability, resistant starch content as well as antioxidant activity of C. auriculatum starch was greatly enhanced by grafting with quercetin. This indicated the potential of quercetin-g-starch in the development of a novel resistant starch with antioxidant activity. PMID- 29572137 TI - Probing the interaction interface of the GADD45beta/MKK7 and MKK7/DTP3 complexes by chemical cross-linking mass spectrometry. AB - GADD45beta is selectively and constitutively expressed in Multiple Myeloma cells, and this expression correlates with an unfavourable clinical outcome. GADD45beta physically interacts with the JNK kinase, MKK7, inhibiting its activity to enable the survival of cancer cells. DTP3 is a small peptide inhibitor of the GADD45beta/MKK7 complex and is able to restore MKK7/JNK activation, thereby promoting selective cell death of GADD45beta-overexpressing cancer cells. Enzymatic MS foot-printing and diazirine-based chemical cross-linking MS (CX-MS) strategies were applied to study the interactions between GADD45beta and MKK7 kinase domain (MKK7_KD) and between DTP3 and MKK7_KD. Our data show that the binding between GADD45beta and MKK7 largely occurs between GADD45beta loop 2 (region 103-117) and the kinase enzymatic pocket. We also show that DTP3 interferes with this GADD45beta/MKK7 interaction by contacting the MKK7 peptides, 113-136 and 259-274. Accordingly, an MKK7_KD Delta(101-136) variant lacking Trp135 did not produce a fluorescence quenching effect upon the binding of DTP3. The assessment of the interaction between GADD45beta and MKK7 and the elucidation of the recognition surfaces between DTP3 and MKK7 significantly advance the understanding of the mechanism underlying the inhibition of the GADD45beta/MKK7 interaction by DTP3 and pave the way to the design of small-molecule DTP3 analogues. PMID- 29572139 TI - Hepatoprotective effects exerted by Poria Cocos polysaccharides against acetaminophen-induced liver injury in mice. AB - Our study was to investigate the potential pharmacological activity of Poria Cocos polysaccharides (PCP) against acetaminophen (APAP)-induced liver injury in mice. PCP-dosed mice were used to conducting biochemical assays of serological liver enzyme (ALT), lactate dehydrogenase (LD), inflammatory cytokines (TNF alpha, IL-6), and immunoassays for functional proteins in the livers. Consequently, APAP-exposed mice resulted in elevated levels of ALT, LD, TNF alpha, IL-6 in sera. Interestingly, PCP-dosed mice exhibited reduced ALT, LD and inflammatory cytokines in blood. Inflammatory infiltration and cell death in liver tissue were decreased following by PCP treatments. Furthermore, immunofluorescence staining showed that AKR7A, c-Jun, Bcl-2-positive cells were increased in PCP-dosed livers in mice, while Bax-labeled cells were decreased. In addition, hepatocellular down-regulated NF-kappaBp65, IkBalpha expressions were observed dose-dependently in PCP-dosed livers in mice. Taken together, the current findings indicate that Poria Cocos polysaccharides exert pharmacological bioeffects against APAP-induced liver injury in mice, and the underlying molecular mechanism is associated to suppressing inflammatory response and apoptosis in liver cells. PMID- 29572140 TI - Preparation, characterization and in vivo antidiabetic effects of polysaccharides from Pachyrrhizus erosus. AB - Polysaccharides were extracted from Pachyrrhizus erosus (PEP) and three fractions (PEP60, PEP80 and PEP95) were separated by ethanol precipitation. Antidiabetic activities of three fractions were evaluated by streptozotocin-induced diabetic mouse model. Three PEP fractions reduced fasting blood glucose levels in mice, and regulated the levels of glycated serum protein, total triglyceride and total cholesterol in serum. In liver, the levels of glycogen content, glutathione peroxidase and superoxide dismutase activities and lipid peroxidation were recovered by PEP fractions. The histological analysis indicated that PEP fractions could protect the tissue structures of pancreas, liver and kidney from diabetic damages. In kidney, PEP fractions decreased the mesangial matrix index and inhibited the expression of transforming growth factor-beta1. PEP95 showed stronger antidiabetic activity than PEP60 and PEP80. PEP95-DS was separated from PEP95 by DEAE-cellulose and Sephadex G-100 column chromatography. The chemical characteristics of PEP95-DS were evaluated. The average molecular weight of PEP95 DS was 11.4kDa, and it was composed of mannose: rhamnose: glucosamine: glucose: galactose: xylose: arabinose was 5.4:1.7:8.5:160.7:11.8:1:2.7. Furthermore, the spectral characteristics of PEP95-DS were analyzed. Our results indicated PEP could be used as a function ingredient in foods to prevent oxidation and diabetes. PMID- 29572141 TI - Hydrogel matrices based on elastin and alginate for tissue engineering applications. AB - Hydrogels from natural polymers are widely used in tissue engineering due to their unique properties, especially when regarding the cell environment and their morphological similarity to the extracellular matrix (ECM) of native tissues. In this study, we describe the production and characterization of novel hybrid hydrogels composed of alginate blended with elastin from bovine neck ligament. The properties of elastin as a component of the native ECM were combined with the excellent chemical and mechanical stability as well as biocompatibility of alginate to produce two hybrid hydrogels geometries, namely 2D films obtained using sonication treatment and 3D microcapsules produced by pressure-driven extrusion. The resulting blend hydrogels were submitted to an extensive physico chemical characterization. Furthermore, the biological compatibility of these materials was assessed using normal human dermal fibroblasts, indicating the suitability of this blend for soft tissue engineering. PMID- 29572142 TI - Rheological characterizations of concentrated binary gum mixtures with xanthan gum and galactomannans. AB - The steady and dynamic shear rheological properties of binary gum mixtures with xanthan gum (XG) and galactomannans (guar gum (GG) and locust bean gum (LBG)) were examined in a concentrated solution (1% w/w) as a function of gum mixing ratio (100/0, 75/25, 50/50, and 0/100). All samples, except for individual GG and LBG, showed high shear-thinning behavior with yield stress. The values of flow (K, etaa,50, and sigmaoc) and dynamic rheological parameters (G' and G") of XG-GG and XG-LBG mixtures were significantly higher compared to XG alone, indicating that the flow and viscoelastic properties of binary gum mixtures were greatly affected by the addition of GG and LBG. The maximum elasticity synergistic interaction for XG-galactomannans mixtures was observed at a mixing ratio of 50/50, showing a greatly positive deviation between measured and calculated values of G'. These results suggest that the synergistic effect of GG and LBG addition on rheological properties of XG appears to be due to intermolecular interaction occurred between XG and galactomannans, as confirmed by dynamic rheological properties. PMID- 29572143 TI - Guar gum-crosslinked-Soya lecithin nanohydrogel sheets as effective adsorbent for the removal of thiophanate methyl fungicide. AB - Rapid increase in use of fungicides for the agricultural and industrial purposes has marked the deterioration of water resources which ultimately affects the human life. Accordingly, various attempts have been made in the removal of these noxious compounds. In the same context, we are presenting biopolymers based nanohydrogel sheets; guar gum-crosslinked-Soya lecithin nanohydrogel sheets (GG crosslinked-SY NHS) used for the effective removal of a fungicide; thiophanate methyl from aqueous solution. Guar gum and soya lecithin were employed as the biopolymers in the fabrication of nanohydrogel sheets due to their non- toxic nature, easy availability, cheapness and significant properties. Due to the presence of highly reactive functional groups onto the surface of GG-crosslinked SY NHS, good adsorption results have been obtained. Maximum adsorption capacity of 59.205mg/g was observed with 20mg GG-crosslinked-SY NHS and 25ppm thiophanate methyl solution concentration as calculated from the Langmuir isotherm. Results showed that neutral pH favoured the adsorption process. Kinetics results were indicative of the physical interactions between the thiophanate methyl and GG crosslinked-SY NHS surface. Thermodynamic results have shown the spontaneous and endothermic adsorption process. PMID- 29572144 TI - Locust bean gum galactomannan hydrolyzed by thermostable beta-d-mannanase may reduce the secretion of pro-inflammatory factors and the release of granule constituents. AB - Locust bean gum (LBG) galactomannan has been claimed to have applications in the biopharmaceutical field. However, the effects of LBG galactomannan on immunomodulatory aspects are not yet clear. The purpose of this study was to over express thermostable beta-d-mannanase from the thermophilic actinomycete Thermobifida fusca BCRC 19214 using a Pichia pastoris expression system. The maximum intracellular beta-d-mannanase activity obtained from the cell-free extract was approximately 40.0U/mL after 72h of cultivating a P. pastoris transformant (pPICZ-man) induced with methanol. Hydrolysis of native LBG galactomannan with 8U/mL beta-d-mannanase for 24h significantly decreased the weight-average molecular weight of LBG galactomannan from 5,580,010 to 3188. Native and hydrolyzed LBG galactomannan in a range of 0-0.2% did not trigger significant cytotoxicity after 24h of treatment compared with the control. The native LBG galactomannan stimulated RAW 264.7 cells to produce cytokine TNF-alpha dose-dependently, but there was no significant IL-1beta or nitric oxide production. The native LBG galactomannan also stimulated beta-hexosaminidase secretion in RBL-2H3 cells. After the native LBG galactomannan was hydrolyzed with beta-d-mannanase, all of the immunological properties disappeared. These results suggest the possible immunomodulatory effects of native LBG galactomannan.

AB - Starch is an abundant, relatively inexpensive and ecofriendly materials which can be easily convert into nanoparticle and also as filler for the preparation of bionanocomposite for wound dressing application. Symmetric and asymmetric Chitosan(C)/PVP(P) films containing porous structure supported with nanostarch (NS) were prepared by salt leaching method for wound dressing application. Symmetric Chitosan/PVP/Nanostarch (CPNS) film with 1% and 3% wt nanostarch was prepared without coating of stearic acid whereas asymmetric Chitosan/PVP/Nanostarch-Stearic acid (CPNS-S) film was prepared by coating of stearic acid. The stearic acid coated surface possesses hydrophobic water repellent, microporous, bacterial anti adhesion property and the stearic acid uncoated hydrophilic surface shows superior antibacterial and noncytotoxicity property with highly porous character. All the symmetric and asymmetric films exhibit almost same mechanical, barrier, swelling and hemolytic property reveals that the stearic acid does not affect the physical and hemolytic property whereas the concentration of nanostarch greatly influence the above property. The reinforcement of nanostarch with chitosan and PVP was proved by TEM and SEM analysis. The CPNS1%-S film shows excellent S. aureus anti adhesion property. Furthermore, the in vivo excision-type wound healing proved that the CPNS1%-S film enhanced the healing effect and increased re-epithelialization and collagen formation. PMID- 29572146 TI - Catalytic characteristics and application of l-asparaginase immobilized on aluminum oxide pellets. AB - l-asparaginase from Escherichia coli (l-ASNase) was covalently immobilized on aluminum oxide pellets (AlOPs) using a cross-linking agent, glutaraldehyde. Maximum immobilization yield (85.0%) was obtained after optimizing immobilization parameters using response surface methodology (RSM). Both free and immobilized l ASNase (AlOP-ASNase) were optimally active at 37 degrees C and pH7.5. However, the bioconjugate exhibited enhanced activity and stability at different pH and temperatures. It had higher affinity (low Km) and was comparatively more stable in presence of some solvents (ethyl acetate, acetone, acetonitrile), metal ions (Ag+, Zn2+) and beta-mercaptoethanol. AlOP-ASNase was reused in a glass column reactor for l-asparagine hydrolysis upto nine successive cycles without any loss in activity. The AlOP-ASNase was effective in lowering l-asparagine level in blanched potato chips indicating its potential use in mitigating acrylamide formation in starchy foods. This cost-effective enzyme preparation had shelf-life of more than 30days and can be effectively used in starch based food industries. PMID- 29572147 TI - Chloroquine diphosphate bearing dextran nanoparticles augmented drug delivery and overwhelmed drug resistance in Plasmodium falciparum parasites. AB - Chloroquine diphosphate (CHQ) is primarily used for the treatment of Plasmodium falciparum malaria at the dose of 500mg orally or 10mg/kg parenterally. However, point mutations in Plasmodiumfalciparum chloroquine resistance transporter (PfCRT) protein and Plasmodium falciparum multidrug resistance protein 1 (Pfmdr1) localized in digestive vacuole membrane, are responsible for CHQ resistance. Therefore, in present investigation, dextran nanoparticles bearing chloroquine diphosphate (CHQ-DEX-NPs) were formulated by solvent diffusion method of size below 70nm with zeta-potential of -20.1+/-3.2mV. FT-IR, DSC and PXRD techniques confirmed the successful loading of drug in nanomatrix system with amorphous attributes. In vitro drug release analysis indicated the Higuchi pattern with diffusion controlled drug release. The IC50 of CHQ-DEX-NPs in sensitive (3D7) and resistant (RKL9) Plasmodium falciparum strains was estimated to be 0.031-MUg/ml and 0.13-MUg/ml significantly lower than 0.059-MUg/ml and 0.36-MUg/ml of CHQ. The augmented therapeutic efficacy of CHQ-DEX-NPs may be credited to deposition of tailored nanoparticles in food vacuoles of malaria parasites owing to the affinity of parasite towards DEX that consequently lower the drug resistance and improved the therapeutic index. In conclusion, CHQ-DEX-NPs must be evaluated under a set of stringent in vivo parameters to establish its therapeutic efficacy in preclinical model.

AB - A novel magnetic bioadsorbent beads composed of Fe3O4, chitosan, and Al(OH)3 (Fe3O4/CS/Al(OH)3) was synthesized by a modified solvothermal and in-situ reaction. The composite adsorbent was characterized by Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, and vibrating sample magnetometer, respectively. Adsorption toward F- onto Fe3O4/CS/Al(OH)3 was investigated as a function of Fe3O4 concentration, initial solution pH, adsorbent dosage, initial fluorion concentration, co-existing ions in water and initial temperature. The addition of Fe3O4 could enhance the adsorption properties of CS/Al(OH)3. The saturated adsorption capacity of magnetic Fe3O4/CS/Al(OH)3 calculated from the Langmuir isotherm model was 76.63mg/g at 298K. The adsorption isotherm of F- followed Langmuir isotherm model and the adsorption kinetics fitted better to the pseudo second order kinetic model. The influence of temperature confirmed that the adsorption was spontaneous and endothermic. The magnetic Fe3O4/CS/Al(OH)3 beads could be easily separated from water under a low magnetic field. PMID- 29572149 TI - Polyguluronate sulfate (PGS) attenuates immunological liver injury in vitro and in vivo. AB - Hepatocyte damage, especially immunological liver injury, is a key process in the pathogenesis of hepatitis virus-induced liver diseases. The aim of this study was to investigate the protective effects of polyguluronate sulfate (PGS) against immunological liver damage. The results showed that PGS significantly reduced the H2O2-induced oxidative stress and increased the cell viability in HepG2 hepatocytes. PGS also suppressed the production of malondialdehyde (MDA), lactate dehydrogenase (LDH), TNF-alpha, and IL-6, while up-regulating the activity of SOD in HepG2 cells. Further, PGS (150 and 300mg/kg/day) significantly attenuated the elevation of serum glutamate pyruvate transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBiL), in addition to liver MDA and NO levels in Con A-induced immunological liver injury within mice (P<0.05). Significant improvements of organ indexes (liver, spleen, and thymus) were observed in PGS-treated mice. PGS also significantly reduced the disorganization of hepatocytes and decreased the inflammatory cell infiltration caused by Con A treatment, suggesting that PGS was able to attenuate Con A-induced liver injury. In conclusion, PGS possesses significant hepatoprotective effects on immunological liver injury in vitro and in vivo, and this may be related to its antioxidant activities. PMID- 29572150 TI - Molecular dynamic of curcumin/chitosan interaction using a computational molecular approach: Emphasis on biofilm reduction. AB - Nanotechnology-based drug delivery systems have been used to enhance bioavailability and biological activities. Chitosan incorporating curcumin can serve as a biocompatible substitute for metallic nanoparticles in preventing biofilm formation of Streptococcus mutans and plaque on teeth. The interactions between chitosan nanoparticle as a carrier and curcumin, a natural antibacterial agent, were simulated. The binding conformation between curcumin-chitosan was obtained using the Lamarckian Genetic Algorithm in AutodockTM software in chitosan nanoparticle. The interaction stability was examined in the molecular dynamic stages, with isothermal-isobaric ensemble in the CHARMM Force Field. The results showed the root mean square deviation (RMSD) and the root mean square fluctuations (RMSF) for all complex's atoms were relaxed after 4ns (RMSD for the all-atoms was 26.81+/-0.1 (A); RMSF 1.13+/-0.02A). For each section, the estimation of RMSD, RMSF, radius of gyration, inter-H bond and other analysis confirmed that, during the first interval;10ns, there was a stable binding between the two sections. Although all bindings disappeared from 10 to 20ns, the curcumin was trapped inside the chitosan nanoparticles, and no release took place until 20ns, after which the curcumin began to release. This trend suggests that chitosan nanoparticle has ability to carry the curcumin. PMID- 29572151 TI - Fire resistant behaviour of cellulosic textile functionalized with wastage plant bio-molecules: A comparative scientific report. AB - Three different wastage plant based bio-molecules named banana peel powder (Musa acuminata) (BPP), coconut shell (Cocos nucifera) extract (CSE) and pomegranate rind (Punica granatum) extract (PRE) have been explored as fire resistant material on the cellulosic polymer (cotton fabric). To this end, extracts have been applied to the cotton fabric in different concentration at elevated temperature for specific time period. Treated cotton fabric showed 6 (BPP), 8.5 (CSE) and 12 (PRE) times lower vertical burning rate compared to the control cotton fabric. Thermo-gravimetry (TG) curves and the limiting oxygen index (LOI) value revealed that the PRE extract (LOI: 32) treated fabric encompassed more thermal stability compared to the BPP (LOI:26) and the CSE (LOI: 27) treated fabric as it showed higher oxygen index and more weight retention (40%) at higher temperature 450 degrees C. Moreover, the carbonaceous samples remained after the burning of the extracts and the treated fabrics showed structural integration and more carbon content [65.6 (PRE extract) and 76.3% (PRE treated cotton)] compared to the fragile, net like char of the control cotton fabric, having less carbon content (49.8%). Gas Chromatography Mass spectroscopy (GC-MS) of the different extracts (CSE, PRE, BPP) used for the study showed the presence of high molecular weight aromatic phenolic compounds, tannin based compound and the nitrogen containing alkaloids, responsible for fire resistant effect of the different extract treated fabric. Besides fire retardancy, all the treated fabric showed attractive natural colour (measured by colour strength values) and there has been no adverse effect on the tensile strength property of the fabric after the treatment.

PMID- 29572153 TI - Amphiphilic polymeric micelles originating from 1,4-beta-D-glucan-g-polyphenylene oxide as the carriers for delivery of docetaxel and the corresponding release behaviors. AB - A novel amphiphilic polymeric drug carrier was synthesized through grafting polymerization of water-soluble 1,4-beta-D-glucan from cotton cellulose tailored and polypropylene oxide (PPO), and then use thereof to synthesize graft copolymer 1,4-beta-D-glucan-PPO-docetaxel (DTX). The products were characterized by FTIR, 1H NMR, and 13C NMR. The physicochemical characteristics of 1,4-beta-D-glucan-PPO and 1,4-beta-D-glucan-PPO-DTX such as molecular weight distribution (MWD), micro morphology, size, critical micelle concentration (CMC), aggregation number of micelle (N), in vitro stability and drug pharmacokinetic study in vivo were investigated. The results reveal that the degree of polymerization (DP) of the water-soluble 1,4-beta-D-glucan from cotton cellulose tailored is equal to 7; the 1,4-beta-D-glucan-PPO surfactant possesses good surface activity while the adduct number of propylene oxide reaches appropriately to 20; the DTX is completely dispersed in water medium with 1,4-beta-D-glucan-PPO-DTX micelle and the drug conjugated percent is up to 40.3%; In vitro study confirms that 1,4-beta-D-glucan PPO-DTX has the capacity for sustained drug release; In plasma, 1,4-beta-D-glucan PPO-DTX exhibits a significantly enhanced Cmax, AUC(0-t) and T1/2 compared with DTX. These results demonstrate that 1,4-beta-D-glucan-PPO has the potential to be used as a novel biocompatible biomaterial for drug delivery. PMID- 29572154 TI - Mechanistic understanding of the phase behavior of supersaturated solutions of poorly water-soluble drugs. AB - Amorphous solid dispersions (ASDs) are a promising formulation strategy to increase both the apparent aqueous solubility and bioavailability of poorly water soluble drugs. Upon dissolution under nonsink conditions, ASDs can generate highly supersaturated drug solutions which can undergo liquid-liquid phase separation (LLPS) and/or crystallization. In this study, the phase behavior of supersaturated solutions generated by antisolvent addition and upon the dissolution of ASDs was evaluated using fluorescence lifetime measurements and several other orthogonal techniques, including steady-state fluorescence spectroscopy, ultraviolet (UV) extinction and concentration profiles, ultracentrifuge measurements and nanoparticle tracking analysis. Ritonavir and lopinavir were chosen as poorly water-soluble model drugs, and the polymer, Kollidon VA64, was selected to form the dispersions. The fluorescence lifetime of the environment-sensitive fluoroprobe, PRODAN, was monitored to determine the occurrence of LLPS and crystallization. It was found that only the 10% w/w drug loading ASDs dissolved to a concentration in solution higher than the LLPS concentration and this led to an increase in the lifetime of PRODAN due to partitioning of the fluoroprobe into the drug-rich phase. In contrast, the 50% w/w drug loading ASDs did not reach the amorphous solubility, pointing to a dissolution behavior controlled by the low water solubility and high hydrophobicity of the drug. Fluorescence lifetime measurements were demonstrated to be extremely useful for the characterization of the phase behavior of supersaturated solutions of poorly water-soluble drugs. PMID- 29572155 TI - N-Terminomics identifies HtrA1 cleavage of thrombospondin-1 with generation of a proangiogenic fragment in the polarized retinal pigment epithelial cell model of age-related macular degeneration. AB - Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly population. Variants in the HTRA1-ARMS2 locus have been linked to increased AMD risk. In the present study we investigated the impact of elevated HtrA1 levels on the retina pigment epithelial (RPE) secretome using a polarized culture system. Upregulation of HtrA1 alters the abundance of key proteins involved in angiogenesis and extracellular matrix remodeling. Thrombospondin-1, an angiogenesis modulator, was identified as a substrate for HtrA1 using terminal amine isotope labeling of substrates in conjunction with HtrA1 specificity profiling. HtrA1 cleavage of thrombospondin-1 was further corroborated by in vitro cleavage assays and targeted proteomics together with small molecule inhibition of HtrA1. While thrombospondin-1 is anti-angiogenic, the proteolytically released N-terminal fragment promotes the formation of tube like structure by endothelial cells. Taken together, our findings suggest a mechanism by which increased levels of HtrA1 may contribute to AMD pathogenesis. The proteomic data has been deposited to the ProteomeXchange Consortium via the PRIDE partner repository with the data set identifier.

AB - The WNT signaling pathways are major regulators of organ development. Ample research over the past few decades revealed that these pathways are critically involved in adult tissue homeostasis and stem cell function as well as the development of chronic diseases, such as cancer and fibrosis. In this review, we will describe the different WNT signal pathways, summarize the current evidence of WNT signal involvement in wound healing and fibrosis, and highlight potential novel therapeutic options for fibrotic disorders targeting WNT signaling pathways. PMID- 29572157 TI - Can a Modified Bosniak Classification System Risk Stratify Pediatric Cystic Renal Masses? AB - PURPOSE: We characterize and apply the modified Bosniak classification system to a cohort of children with cystic renal lesions and known surgical pathology. MATERIALS AND METHODS: We identified all patients at our institution with cystic renal masses who also underwent surgery for these lesions. Patients without available preoperative imaging or pathology were excluded. All radiological imaging was independently reviewed by a pediatric radiologist blinded to pathological findings. Imaging characteristics (size, border, septations, calcifications, solid components, vascularity) were recorded from the most recent preoperative ultrasounds and computerized tomograms. The modified Bosniak classification system was applied to these scans and then correlated with final pathology. RESULTS: A total of 22 patients met study criteria. Median age at surgery was 6.1 years (range 11 months to 16.8 years). Of the patients 12 (54.5%) underwent open nephrectomy, 6 (27.3%) open partial nephrectomy, 2 (9.1%) laparoscopic cyst decortication, 1 (4.5%) open renal biopsy and 1 (4.5%) laparoscopic partial nephrectomy. Final pathology was benign in 9 cases (41%), intermediate in 6 (27%) and malignant in 7 (32%). All malignant lesions were modified Bosniak class 4, all intermediate lesions were modified class 3 or 4 and 8 of 9 benign lesions (89%) were modified class 1 or 2. CONCLUSIONS: Cystic renal lesions in children with a modified Bosniak class of 1 or 2 were most often benign, while class 3 or 4 lesions warranted surgical excision since more than 90% of masses harbored intermediate or malignant pathology. The modified Bosniak classification system appears to allow for a reasonable clinical risk stratification of pediatric cystic renal masses. PMID- 29572158 TI - A Phase I/II Trial of the Combination of Azacitidine and Gemtuzumab Ozogamicin for Treatment of Relapsed Acute Myeloid Leukemia. AB - INTRODUCTION: Treatment with hypomethylating agent therapy might enhance anti CD33 monoclonal antibody-mediated cytotoxicity against acute myeloid leukemia (AML) blasts through epigenetic effects on Syk and SHP-1 expression. PATIENTS AND METHODS: In the present phase I/II study, we treated patients with relapsed or refractory AML with azacitidine, followed by 2 doses of gemtuzumab ozogamicin (GO) at 6 mg/m2, the Food and Drug Administration-approved dose and schedule at study initiation. We sought to determine the maximum tolerated dose and clinical activity of this combination therapy. Secondarily, we aimed to determine whether baseline Syk and SHP-1 expression can be used as predictive biomarkers of treatment response. RESULTS: The established maximum tolerated dose was azacitidine 75 mg/m2 daily for 6 consecutive days, followed by GO 6 mg/m2 on days 7 and 21. Of the 50 evaluable patients, 12 (24%) obtained complete remission (CR) or CR with incomplete peripheral blood recovery (CRp). No dose-limiting toxicities were observed in phase I, and no patient developed hepatic sinusoidal obstructive syndrome. Although no significant correlation was found between Syk and SHP-1 expression and the clinical response to combination therapy, in vitro studies repeatedly demonstrated that azacitidine-treated AML cells had an increased response to GO treatment. CONCLUSION: Our study found that the combination of GO with azacitidine is relatively well tolerated, with response rates similar to those with GO monotherapy at higher doses. Differences in the GO drug schedule, dose level, and frequency might explain the discrepant response rates between our study and others, suggesting that the optimal GO dose remains unclear, especially when combined with hypomethylating agent therapy. PMID- 29572159 TI - Elderly Patients (Age 70 Years or Older) With Secondary Acute Myeloid Leukemia or Acute Myeloid Leukemia Developed Concurrently to Another Malignant Disease. AB - INTRODUCTION: Secondary acute myeloid leukemia (sAML) remains a therapeutic challenge. In elderly patients with AML, it is unclear whether sAML displays an inferior outcome compared with de novo AML. PATIENTS AND METHODS: We studied AML with an antecedent of hematologic disease, treatment-related AML, or AML occurring concurrently to another malignancy in a single-center cohort of patients aged 70 and older with AML. The study included 169 patients who were compared with a cohort of patients with de novo AML, without any prior history of malignant disorders, seen during the same period of time. RESULTS: Hematologic antecedents or presence of prior/concurrent solid malignancy did not impact complete remission rates and overall survival. In multivariate analysis, sAML appeared without independent prognostic value in the elderly. CONCLUSION: Our results support that sAML and de novo AML in elderly patients are not prognostically distinct entities. They should therefore not be considered separately when investigating outcomes and new treatment strategies. PMID- 29572160 TI - Biomaterials for drug delivery patches. AB - The limited efficiency of conventional drugs has been instigated the development of new and more effective drug delivery systems (DDS). Transdermal DDS, are associated with numerous advantages such its painless application and less frequent replacement and greater flexibility of dosing, features that triggered the research and development of such devices. Such systems have been produced using either biopolymer; or synthetic polymers. Although the first ones are safer, biocompatible and present a controlled degradation by human enzymes or water, the second ones are the most currently available in the market due to their greater mechanical resistance and flexibility, and non-degradation over time. This review highlights the most recent advances (mainly in the last five years) of patches aimed for transdermal drug delivery, focusing on the different materials (natural, synthetic and blends) and latest designs for the development of such devices, emphasizing also their combination with drug carriers that enable enhanced drug solubility and a more controlled release of the drug over the time. The benefits and limitations of different patches formulations are considered with reference to their appliance to transdermal drug delivery. Furthermore, a record of the currently available patches on the market is given, featuring their most relevant characteristics. Finally, a list of most recent/ongoing clinical trials regarding the use of patches for skin disorders is detailed and critical insights on the current state of patches for transdermal drug delivery are also provided. PMID- 29572161 TI - Host-pathogen dynamics through targeted secretome analysis of stimulated macrophages. AB - The pattern recognition receptors (PRRs) facilitate an organism's first line of defense against interlopers and shape the overall innate immune response through sensing and sampling pathogen-associated molecular patterns (PAMPs). The Toll like receptor (TLR) family is the prototypic PRR family. Upon recognition of PAMPs, TLRs promote MyD88 dependent and independent responses. Understanding how different PAMPs are recognized by their specific TLRs and how pathogen recognition initiates immune activation is an intense area of research. Previously, we have reported the discovery of the temporal changes in signaling cascades of macrophage proteome and secretome post-stimulation with three different PAMPs. To extend our global proteomics approach to targeted protein abundance quantification, we describe the macrophage secretome targeted proteomics assay. We chose three different pathogens that specifically stimulate diverse TLRs (TLR2, TLR4, and TLR7). Using a simple targeted proteomics approach, combining data-dependent acquisition with an inclusion list, an array of cytokines, chemokines, and transcription factors can be profiled for their secretome abundance. This strategy facilitates the profiling and validation of pathogen-specific temporal changes in the macrophage secretome. PMID- 29572162 TI - Integrated SWATH-based and targeted-based proteomics provide insights into the retinal emmetropization process in guinea pig. AB - : Myopia is generally regarded as a failure of normal emmetropization process, however, its underlying molecular mechanisms are unclear. To investigate the retinal protein profile changes during emmetropization, we studied differential protein expressions of ocular growth in young guinea pigs at 3 and 21 days old respectively, when significant axial elongation was detected (P < 0.001, n = 10). Independent pooled retinal samples of both eyes were subjected to SWATH mass spectrometry (MS) followed by bioinformatics analysis using cloud-based platforms. A comprehensive retina SWATH ion-library consisting of 3138 (22,871) unique proteins (peptides) at 1% FDR was constructed. 40 proteins were found to be significantly up-regulated and 8 proteins down-regulated during emmetropization (>=log2 of 0.43 with >=2 peptides matched per protein; P < 0.05). Using pathway analysis, the most significant pathway identifiable was 'phototransduction' (P = 1.412e-4). Expression patterns of 7 proteins identified in this pathway were further validated and confirmed (P < 0.05) with high resolution Multiple Reaction Monitoring (MRM-HR) MS. Combining discovery and targeted proteomics approaches, this study for the first time comprehensively profiled protein changes in the guinea pig retina during normal emmetropization associated eye growth. The findings of this study are also relevant to the myopia development, which is the result of failed emmetropization. SIGNIFICANCE: Myopia is considered as a failure of emmetropization. However, the underlying biochemical mechanism of emmetropization, a visually guided process in which eye grows towards the optimal optical state of clear vision during early development, is not well understood. Retina is known as the key tissue to regulate this active eye growth. we studied eye growth of young guinea pigs and harvested their retinal tissues. A comprehensive SWATH ion library with identification of a total 3138 unique proteins were established, in which 48 proteins exhibited significant differential expressions between 3 and 21 days old. After MRM-HR confirmation, 'phototransduction' were found as the most active pathway during emmetropic eye growth. This study is the first in discovering key retinal protein players and pathways which are presumably orchestrated by biological mechanism(s) underlying emmetropization. PMID- 29572163 TI - The cardiac proteome in patients with congenital ventricular septal defect: A comparative study between right atria and right ventricles. AB - : Right ventricle (RV) remodelling occurs in neonatal patients born with ventricular septal defect (VSD). The presence of a defect between the two ventricles allows for shunting of blood from the left to right side. The resulting RV hypertrophy leads to molecular remodelling which has thus far been largely investigated using right atrial (RA) tissue. In this study we used proteomic and phosphoproteomic analysis in order to determine any difference between the proteomes for RA and RV. Samples were therefore taken from the RA and RV of five infants (0.34 +/- 0.05 years, mean +/- SEM) with VSD who were undergoing cardiac surgery to repair the defect. Significant differences in protein expression between RV and RA were seen. 150 protein accession numbers were identified which were significantly lower in the atria, whereas none were significantly higher in the atria compared to the ventricle. 19 phosphorylation sites (representing 19 phosphoproteins) were also lower in RA. This work has identified differences in the proteome between RA and RV which reflect differences in contractile activity and metabolism. As such, caution should be used when drawing conclusions based on analysis of the RA and extrapolating to the hypertrophied RV. SIGNIFICANCE: RV hypertrophy occurs in neonatal patients born with VSD. Very little is known about how the atria responds to RV hypertrophy, especially at the protein level. Access to tissue from age-matched groups of patients is very rare, and we are in the unique position of being able to get tissue from both the atria and ventricle during reparative surgery of these infants. Our findings will be beneficial to future research into heart chamber malformations in congenital heart defects. PMID- 29572164 TI - Surgical management of severe ocular surface injury due to Roman candle explosion accidents. AB - PURPOSE: To report the clinical features, management, and outcomes of patients with ocular surface damage secondary to Roman candle explosion accidents. METHODS: Retrospective, noncomparative, interventional case series of 11 patients with Roman candle explosion-related ocular surface injuries referred to the Cincinnati Eye Institute between 2007 and 2016. RESULTS: Eleven patients (10 male, 1 female, mean age 22.4 years) sustained unilateral ocular surface injuries with presenting visual acuity ranging from count fingers to light perception. All patients had severe limbal stem cell deficiency with total ocular surface failure. Eight eyes received a conjunctival-limbal autograft (CLAU) with a keratolimbal allograft (KLAL), 1 eye received a living related-conjunctival limbal allograft (lr-CLAL) with a KLAL, and 2 eyes received a CLAU with lr-CLAL. Nine eyes underwent subsequent penetrating keratoplasty, and 7 eyes had reconstructive eyelid surgery. Nine eyes demonstrated improved visual acuity at last follow-up; seven eyes demonstrated a stable ocular surface at last follow up. Nonadherence was noted in 7 patients, either with poor adherence with post operative treatment or poor follow-up; this portended a worse visual result. CONCLUSIONS: Roman candle-related accidents can lead to severe ocular surface injury. Despite total ocular surface failure, these eyes can achieve good postoperative visual results following limbal stem cell transplantation and subsequent keratoplasty with appropriate compliance. PMID- 29572165 TI - Using Recent BCI Literature to Deepen our Understanding of Clinical Neurofeedback: A Short Review. AB - In their recent paper, Alkoby et al. (2017) provide the readership with an extensive and very insightful review of the factors influencing NeuroFeedback (NF) performance. These factors are drawn from both the NF literature and the Brain-Computer Interface (BCI) literature. Our short review aims to complement Alkoby et al.'s review by reporting recent additions to the BCI literature. The object of this paper is to highlight this literature and discuss its potential relevance and usefulness to better understand the processes underlying NF and further improve the design of clinical trials assessing NF efficacy. Indeed, we are convinced that while NF and BCI are fundamentally different in many ways, both the BCI and NF communities could reach compelling achievements by building upon one another. By reviewing the recent BCI literature, we identified three types of factors that influence BCI performance: task-specific, cognitive/motivational and technology-acceptance-related factors. Since BCIs and NF share a common goal (i.e., learning to modulate specific neurophysiological patterns), similar cognitive and neurophysiological processes are likely to be involved during the training process. Thus, the literature on BCI training may help (1) to deepen our understanding of neurofeedback training processes and (2) to understand the variables that influence the clinical efficacy of NF. This may help to properly assess and/or control the influence of these variables during randomized controlled trials. PMID- 29572166 TI - The Effects of N-terminal Mutations on beta-amyloid Peptide Aggregation and Toxicity. AB - Human amyloid beta1-42 (hAbeta1-42) peptides are known to self-aggregate into oligomers that contribute to the degeneration of neurons and development of Alzheimer's disease (AD) pathology. Unlike humans, rodents do not develop AD, possibly due to differences in three amino acids (R5G, Y10F and H13R) within the hydrophilic N-terminal domain of Abeta1-42. This is partly supported by evidence that hAbeta1-42 is more prone to fibrillization and has a higher cellular toxicity than rodent Abeta1-42 (rAbeta1-42). Mutagenesis studies, however, have shown that correlation between fibrillization potential and toxicity is not always direct. Thus, to understand better how N-terminal mutations can affect hAbeta1-42 toxicity through oligomerization, we evaluated fibrillization kinetics, oligomer sizes and toxicity profiles of double mutant (human toward rodent) Abeta1-42. Additionally, we tested the mutant peptides in combination with hAbeta1-42, to assess effects on hAbeta1-42 aggregation/toxicity. Our results clearly show that double mutations to humanize rAbeta1-42 result in a significantly reduced efficiency of fibril formation, as determined by Thioflavin T aggregation assays and confirmed with electron micrographic studies. Interestingly, the mutants are still able to aggregate into oligomers, which are predominantly larger than those comprised of hAbeta1-42. Our cell viability experiments further showed a rank order of oligomer toxicity of hAbeta1-42 > rAbeta1-42 ? mutant Abeta1-42, suggesting that toxicity can be influenced by N terminal Abeta1-42 mutations via reduction of fibril formation and/or alteration of oligomer size. These results, taken together, confirm that N-terminal mutations can affect Abeta fibril and oligomer formation with reduced toxicity despite lying outside the core amyloid region of Abeta peptide. PMID- 29572167 TI - Radiologic Analysis of Kinematic Characteristics of Modic Changes Based on Lumbar Disc Degeneration Grade. AB - OBJECTIVE: The kinematic characteristics of Modic changes (MCs) in the lumbar spine have rarely been reported; furthermore, the effect of disc degeneration (DD) on segmental motion has not been considered in analyzing the motion characteristics of MCs. Therefore, this study was designed to evaluate the kinematic characteristics of MCs based on different DD grades. METHODS: 894 patients with 4470 lumbar segments were reviewed, and those with MCs were selected for segmental motion evaluation. MC type was defined as 0, I, II, and III, and DD grade was classified into 5 groups from grade A to grade E. Segmental angular and translational motion were calculated from X-ray images in positions of flexion and extension, and the absolute values of the differences were recorded. RESULTS: MCs were observed in 308 segments from 260 patients. No MC was found in DD grade A, and MC III was not observed in DD grade B. MC I was found to significantly increase angular motion in the DD grade E group, and MC II could enlarge translational motion in the DD grade D group (all P < 0.05); MC III had the lowest segmental motion in both angular and translational motion; There was no statistical difference in angular and translational motion between MC I and II in all DD grade groups (all P > 0.05). CONCLUSIONS: MC III indicates the final stable phase of segmental motion. MC I might increase angular motion, and MC II would increase certain translational motions in the segments that were believed to be stable. PMID- 29572168 TI - Lymphocytic Hypophysitis Secondary to Ruptured Rathke Cleft Cyst: Case Report and Literature Review. AB - BACKGROUND: Lymphocytic hypophysitis is a rare inflammatory lesion in the sellar region. Lymphocytic hypophysitis secondary to ruptured Rathke cleft cyst (RCC) is even more rarely seen. Clinical characteristics, treatment strategies, and prognosis remain elusive. CASE DESCRIPTION: A 58-year-old Chinese woman with a 3 year history of intermittent headache and new development of polydipsia, polyuria, and binocular visual acuity decline over the past 4 months was admitted to our hospital. On admission, endocrine results were normal. Ophthalmic testing showed bitemporal visual field deficits and decreased visual acuity of both eyes. Pituitary dynamic magnetic resonance imaging showed a cystic sellar lesion measuring 5.6 * 5.2 * 6.2 mm with tumor shrinkage compared with initial neuroimaging. Transsphenoidal surgery was performed for tumor resection. An additional biopsy of the anterior pituitary lobe was performed because of intraoperative abnormal appearances of the pituitary gland. Pathology examinations revealed the specimen of the cystic lesion to be RCC and exhibited infiltration of massive lymphocytes, diffused plasmocytes, and eosinophils that were diagnostic of lymphocytic hypophysitis in the anterior pituitary lobe. During follow-up, the lesion of lymphocytic hypophysitis showed spontaneous shrinkage in the absence of steroid treatment after RCC resection. Final diagnosis was lymphocytic hypophysitis secondary to ruptured RCC. CONCLUSIONS: We present a rare case of lymphocytic hypophysitis secondary to ruptured RCC and provide clinical data of such lesions in the literature. Full understanding of the clinical features plays an important role in diagnosis and treatment of lymphocytic hypophysitis secondary to ruptured RCC. PMID- 29572169 TI - Surgical Management of Adverse Radiation Effects After Gamma Knife Radiosurgery for Cerebral Arteriovenous Malformations: A Population-Based Cohort Study. AB - OBJECTIVE: The goal of this study is to report our experience in the surgical treatment of cerebral arteriovenous malformations (cAVMs) related permanent symptomatic adverse radiation effects (PSAREs), to clarify an appropriate surgical management and to identify the risk factors related to their development. METHODS: We evaluated 549 patients treated with Gamma Knife radiosurgery (GKRS) for cAVMs with a follow-up of at least 8 years. Univariate and multivariate analyses were used to test different risk factors related to the development of PSARE. We retrospectively reviewed the records of these patients to analyze the clinical outcome. RESULTS: Fourteen patients (2.5%) developed PSARE and were submitted to surgery. Higher average treated volume represents a significant risk factors for the development of PSARE (P < 0.05); on the other hand, older age and higher average dose reduce the risk of PSARE (P < 0.05). A favorable clinical outcome was achieved in 13 patients (93%) after surgery; in 1 patient, the unfavorable outcome was due to hemorrhage that occurred months after GKRS. Serial MRI scans following either surgical removal of the nodule or Ommaya reservoir positioning showed progressive reduction of brain edema in all cases. CONCLUSIONS: The management of PSARE is controversial, especially for cAVMs treated with SRS. Surgical removal is rarely needed, but-if unavoidable-it can be a valuable option in experienced hands. A careful preoperative planning is always necessary to detect pathologic blood flow through the PSARE. PMID- 29572170 TI - Favorable Long-Term Outcomes for Positional Vertebral Artery Occlusion with Treatment Strategy Prioritizing Spinal Fusion Surgery. AB - OBJECTIVE: Positional vertebral artery occlusion (PVAO) has a fundamental problem in the definition. We analyzed the long-term outcomes with a redefinition of the rare clinical entities as PVAO for a broader conceptualization, and discuss the efficacy of fusion surgery as a treatment option. METHODS: We analyzed the clinical and radiologic characteristics and outcomes in 8 patients with PVAO who experienced cerebral ischemia during a 10-year period at our institution. The follow-up periods ranged from 60 to 132 months (mean, 93.5 months). All patients were initially treated conservatively with external fixation. If spinal instability was observed at the initial evaluation or a second stroke occurred during conservative treatment, cervical spinal fusion was performed with special consideration for vertebral artery dominance and the presence of its collateral flow regardless of the type of stroke. RESULTS: Conservative therapy was completed for 2 patients, and spinal fusion was performed for the other 6 patients. None of the patients experienced a recurrence of symptoms after discharge until the final follow-up visit, and the outcomes were excellent. Long term functional outcomes were dependent on the patient's condition before the onset of stroke and the neurologic deficits resulting from the initial or recurrent stroke induced by embolism. CONCLUSIONS: We report our single-center experience with PVAO in which 75% of patients had embolic stroke. Because embolic stroke may have a greater risk of recurrence affecting the long-term outcomes, it should be prevented. In addition, if surgical intervention is necessary, spinal fusion surgery may be an effective option. PMID- 29572171 TI - Rare Case of Cerebrospinal Fluid Proctorrhea Caused by Anterior Sacral Meningocele with Rectothecal Fistula. AB - BACKGROUND: Anterior sacral meningocele (ASM) leading to secondary rectothecal fistula is extremely rare, and to date only 5 such cases have been described in the world literature. CASE DESCRIPTION: We describe an uncomplicated case of a 52 year-old female patient presenting with cerebrospinal fluid leak from the anus who was investigated and found to have an ASM with rectothecal fistula. The ASM and rectothecal fistula were subsequently repaired using a posterior approach. Pertinent literature review, clinical findings, neuroimaging, and surgical management are described for these rare lesions. CONCLUSION: Early diagnosis and surgical disconnection of the fistulous tract led to satisfactory outcome in the present case and avoided the catastrophic complication of meningitis. PMID- 29572172 TI - Double Retrotransverse Foramen of Atlas (C1). AB - BACKGROUND: The retrotransverse foramen is a nonmetric variant of C1 that consists of an abnormal accessory foramen on the posterior root of the transverse process. CASE DESCRIPTION: During a study on the prevalence of the retrotransverse foramen in 150 dry C1 vertebrae, we observed an exceptional C1 (0.67%) with a right double retrotransverse foramen of the 14 C1 vertebrae (9.3%). This has not been reported previously in the literature. No osteogenic reaction and no degenerative signs were observed in this C1 with the double retrotransverse foramen. CONCLUSIONS: Neurosurgeons should be aware of the possible presence of the "conventional" retrotransverse foramen and the "exceptional" double retrotransverse foramen so that they can safely plan to prevent surgical complications. This will thus ensure better patient management by neurosurgeons. PMID- 29572173 TI - Life Expectancy of Brazilian Neurosurgeons. AB - BACKGROUND: Life expectancy (LE) refers to the number of years that an individual is expected to survive. Emphasis is frequently placed on the relationship between LE and the conditions under which a population lives, but fewer studies have investigated the relationship between stress factors associated with specific professions and their effects on LE. The aim of this study is to evaluate Brazilian neurosurgeons' life expectancies (BNLEs) and compare them with those of physicians (both Brazilian and foreign) from other fields, as well as with Brazilian nondoctors. METHODS: The Brazilian Society of Neurosurgery death registry was used to obtain data that compared LEs from non-neurosurgeon physicians, as described in the national and international literature. BNLEs were also compared with the LEs of Brazilian citizens. RESULTS: Fifty-one neurosurgeons died between 2009 and 2016. All were males. The mean age at death was 68.31 +/- 17.71 years. Among all-cause mortality, the breakdown was 20% cardiovascular diseases, 39% malignancies, 10% external factors, 6% gastrointestinal disorders, 12% neurologic illnesses, and 14% unknown causes. BNLE was shorter than LE of male Brazilian citizens. CONCLUSIONS: LE was similar among neurosurgeons and other doctors but shorter compared with Brazilian citizens. Further research is needed to provide data that can add to and confirm these results. PMID- 29572174 TI - Entire Orifice Blocking-Assisted Microsurgical Treatment: Clipping of Intracranial Giant Wide-Neck Paraclinoid Aneurysms. AB - OBJECTIVE: Giant wide-neck paraclinoid aneurysms remain a formidable challenge for neurosurgeons due to the brisk retrograde blood flow during surgical clipping. Theoretically, Entire orifice blockade (EOB) by placing a longitudinal intracarotid balloon catheter across the aneurysm neck could achieve a good vascular control in treating cerebral aneurysms, but related studies have been scarce. The aim of this study was to evaluate the safety and efficiency of the EOB-assisted microsurgical technique for treating giant wide-neck paraclinoid aneurysms. METHODS: Clinical data and treatment summaries of patients with giant wide-neck paraclinoid aneurysms who underwent EOB-assisted microsurgical clipping were retrospectively reviewed. RESULTS: A total of 26 patients were analyzed. All but 3 patients harbored unruptured aneurysms. The mean largest diameter of the aneurysms was 26.8+/-2.0 mm, and the mean neck size was 12.5+/-2.4 mm. All lesions were successfully clipped without residual aneurysms. Post-operative images revealed no major branch occlusion due to thromboembolic complications. Four patients presented neurologic deficits caused by vasospasm, 3 of which were completely resolved by postoperative treatment. At a mean follow-up time of 1.86 +/- 0.95 years (range, 0.5-3.5 years), none of the patients died, and 96.2% (n = 25) of the patients had favorable clinical outcomes with modified Rankin Scale values of 0-2. CONCLUSIONS: For patients with giant wide-neck paraclinoid aneurysms, EOB-assisted microsurgical clipping is a safe and useful procedure for obtaining vascular control, for softening and shrinking the aneurysm sac and for providing a wide and clean operative field that allows the clip to be effectively placed. PMID- 29572175 TI - Motor Cortex Stimulation Regenerative Effects in Peripheral Nerve Injury: An Experimental Rat Model. AB - BACKGROUND: Immediate microsurgical nerve suture remains the gold standard after peripheral nerve injuries. However, functional recovery is delayed, and it is satisfactory in only 2/3 of cases. Peripheral electrical nerve stimulation proximal to the lesion enhances nerve regeneration and muscle reinnervation. This study aims to evaluate the effects of the motor cortex electrical stimulation on peripheral nerve regeneration after injury. METHODS: Eighty rats underwent right sciatic nerve section, followed by immediate microsurgical epineural sutures. Rats were divided into 4 groups: Group 1 (control, n = 20): no electrical stimulation; group 2 (n = 20): immediate stimulation of the sciatic nerve just proximal to the lesion; Group 3 (n = 20): motor cortex stimulation (MCS) for 15 minutes after nerve section and suture (MCSa); group 4 (n = 20): MCS performed over the course of two weeks after nerve suture (MCSc). Assessment included electrophysiology and motor functional score at day 0 (baseline value before nerve section), and at weeks 4, 8, and 12. Rats were euthanized for histological study at week 12. RESULTS: Our results showed that MCS enhances functional recovery, nerve regeneration, and muscle reinnervation starting week 4 compared with the control group (P < 0.05). The MCS induces higher reinnervation rates even compared with peripheral stimulation, with better results in the MCSa group (P < 0.05), especially in terms of functional recovery. CONCLUSIONS: MCS seems to have a beneficial effect after peripheral nerve injury and repair in terms of nerve regeneration and muscle reinnervation, especially when acute mode is used. PMID- 29572176 TI - Perineural Spread of Nonmelanoma Skin Cancer to the Brachial Plexus: Identifying Anatomic Pathway(s). AB - BACKGROUND: Perineural spread leading to brachial plexopathy has recently been described in cases of melanoma. The occurrence and mechanism for nonmelanoma skin cancer spread to the brachial plexus is poorly understood. METHODS: A retrospective chart review of the Mayo Clinic database was conducted to identify patients with nonmelanoma skin cancer and brachial plexopathy between 2000 and 2017. Inclusion criteria were a history of nonmelanoma skin cancer, a clinical diagnosis of brachial plexopathy, imaging features of perineural spread, and a positive result of examination of a biopsy specimen showing tumor in a skin nerve. RESULTS: Thirty-seven patients with a history of nonmelanoma skin cancer and brachial plexopathy were identified. Inclusion criteria were fulfilled in 2 cases of cutaneous squamous cell carcinoma. One case of recurrent basal cell carcinoma with perineural spread confirmed in the brachial plexus by pathologic examination was excluded because confirmatory evidence of perineural spread from the skin to the brachial plexus was not available. CONCLUSIONS: Perineural spread of nonmelanoma skin cancer leading to brachial plexopathy is rare. Our 2 cases and the cases found in the literature demonstrate different entry points to the neural highway resulting in neurologic deficits. The cervical plexus serves as a hub for further spread in certain cases of perineural spread of skin cancer. PMID- 29572177 TI - Metastatic Spine Tumor Epidemiology: Comparison of Trends in Surgery Across Two Decades and Three Continents. AB - BACKGROUND: Indications for surgery for symptomatic spinal metastases have become better defined in recent years, and suitable outcome measures have been established against a changing backdrop of patient characteristics, tumor behavior, and oncologic treatments. Nonetheless, variations still exist in the local management of patients with spinal metastases. In this study, we aimed to review global trends and habits in the surgical treatment of symptomatic spinal metastases, and to examine how these have changed over the last 25 years. METHODS: In this cohort study of consecutive patients undergoing surgery for symptomatic spinal metastases, data were collected using a secure Internet database from 22 centers across 3 continents. All patients were invited to participate in the study, except those unable or unwilling to give consent. RESULTS: There was a higher incidence of colonic, liver, and lung carcinoma metastases in Asian countries, and more frequent presentation of breast, prostate, melanoma metastases in the West. Trends in surgical technique were broadly similar across the centers. Overall survival rates after surgery were 53% at 1 year, 31% at 2 years, and 10% at 5 years after surgery (standard error 0.013 for all). Survival improved over successive time periods, with longer survival in patients who underwent surgery in 2011-2016 compared with those who underwent surgery in earlier time periods. CONCLUSIONS: Surgical habits have been fairly consistent among countries worldwide and over time. However, patient survival has improved in later years, perhaps due to medical advances in the treatment of cancer, improved patient selection, and operating earlier in the course of disease. PMID- 29572178 TI - Long noncoding RNA BDNF-AS is downregulated in cervical cancer and has anti cancer functions by negatively associating with BDNF. AB - PURPOSE: We investigated expression and mechanism long noncoding RNA BDNF-AS in human cervical cancer (CC). METHODS: BDNF-AS expressions were examined by qPCR in CC cell lines and human CC tumors. CC cell lines, SiHa and DoTc2-4510 were transduced with lentivirus to ectopically overexpress BDNF-AS. Possible anti cancer effects of BDNF overexpression were examined on CC in vitro proliferation and migration, and in vivo transplantation. Human BDNF gene expression was also examined in CC cell lines and tumors. In CC cells with overexpressed BDNF-AS, BDNF was upregulated to examine its direct effect in NDNF-AS-modulated CC proliferation and migration. RESULTS: BDNF was downregulated in both CC cells and human CC tumors. In CC cells, BDNF-AS overexpression is anti-cancer by inhibiting proliferation and migration in vitro, and transplantation in vivo. BDNF was inversely expressed as BDNF-AS in CC. Upregulation of BDNF in BDNF-AS overexpressed CC cells reversed the anti-cancer effects of BDNF-AS. CONCLUSION: BDNF-AS is downregulated in CC. Overexpressing BDNF-AS may inhibit CC, possibly through inverse regulation on BDNF. PMID- 29572179 TI - Continuous application of compressive force induces fusion of osteoclast-like RAW264.7 cells via upregulation of RANK and downregulation of LGR4. AB - AIMS: During orthodontic treatment, facilitating osteoclastic bone resorption in the alveolar bone exposed to the compressive force (CF) is an important factor for tooth movement. The present study investigated the effect of CF stimulation on the differentiation of RAW264.7 cells from precursors to mature osteoclasts. MAIN METHODS: The cells were continuously stimulated with 0.3, 0.6, or 1.1 g/cm2 CF-which was generated by increasing the volume of culture medium in the wells of a 96-well plate-in the presence or absence of receptor activator of nuclear factor kappaB (RANK) ligand (RANKL) for 4 days. KEY FINDINGS: In the presence of RANKL, the number of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells and the mRNA levels of dendritic cell-specific transmembrane protein (DC-STAMP) and osteoclast-stimulatory transmembrane protein (OC-STAMP) were increased by application of 0.6 and 1.1 g/cm2 CF as compared to 0.3 g/cm2 CF. The mRNA level of RANK was upregulated whereas that of leucine-rich repeat containing G-protein-coupled receptor (LGR)4-another RANKL receptor was downregulated by 0.6 and 1.1 g/cm2 CF as compared to 0.3 g/cm2 CF in the absence of RANKL. The proportion of cells with nuclear translocation of the nuclear translocation of nuclear factor of activated T cells (NFAT)c1 was increased by 0.6 and 1.1 g/cm2 CF in the presence of RANKL. SIGNIFICANCE: Continuous application of CF induced the differentiation of RAW264.7 cells into TRAP positive multinuclear cells by enhancing the expression of DC- and OC-STAMP and the nuclear translocation of NFATc1. This may result from the CF-induced increase in RANK and decrease in LGR4 expression. PMID- 29572180 TI - Two tandem repeats of mHSP70407-426 enhance therapeutic antitumor effects of a recombined vascular endothelial growth factor (VEGF) protein vaccine. AB - AIMS: Active immunization with human vascular endothelial growth factor (hVEGF) vaccines provides a therapeutic option instead of bevacizumab therapy. However, the immunity to self-molecule is difficult to elicit due to immune tolerance. A bioactive peptide of two tandem repeats of mHSP70407-426 (M2) has exhibited potent adjuvant ability in our previous study, and the aim of this study was to explore whether M2 could assist hVEGF to display enhanced therapeutic anti-tumor effects. MAIN METHODS: The anti-tumor effects of hVEGF-M2 vaccine were evaluated in both H22 hepatocellular carcinoma and Lewis lung tumor models. CD31 analysis of excised tumors was used to evaluate anti-angiogenesis effects. The titers of anti-VEGF antibody was detected by ELISA and verified by western blot analyses, and the effects of immune sera on HUVEC differentiation were investigated by tube formation assay. KEY FINDINGS: M2 could assist hVEGF to exhibit more favorable therapeutic anti-tumor growth and metastasis effects than hVEGF. Meanwhile, high titer of anti-VEGF antibody was detected in hVEGF-M2 immunized mice sera by ELISA and verified by western blot analysis. Sera from hVEGF-M2 immunized mice could more significantly inhibit HUVEC tube formation than hVEGF immune serum. The hVEGF-M2-immune sera could more effectively inhibit H22 tumor growth and extend the survival rates of H22 tumor bearing mice than hVEGF-immune sera. CD31 analysis of the excised tumors verified a significant reduction in vessel density after hVEGF-M2 vaccination. SIGNIFICANCE: M2 could assist hVEGF to display enhanced anti-tumor effects, which are important for the further application of M2 to enhance antigen-specific immune responses. PMID- 29572182 TI - Opening-wedge high tibial osteotomy performed with locking plate fixation (TomoFix) and early weight-bearing but without filling the defect. A concise follow-up note of 48 cases at 10 years' follow-up. AB - INTRODUCTION: Use of a locking plate during medial opening high tibial osteotomy (HTO) eliminates the need to fill the defect and its associated complications. It also allows early weight-bearing. Since long-term data with this type of construct are rare, we wanted to report the outcomes of a 51-patient cohort evaluated after a mean follow-up of 10.2years. The goals were to determine (1) the HTO survival and whether the correction was maintained between 2 and 10years later, (2) the stability of the functional outcomes, (3) the complication rate related to use of locking plates. HYPOTHESIS: The correction following medial opening HTO with a TomofixTM plate without void filling is maintained after 10years' follow-up. MATERIAL AND METHODS: Fifty-one patients ranging from 37 to 72years of age at the time of surgery between 2003 and 2005 underwent a medial opening HTO that was stabilized with a TomofixTM locking plate (Synthes, Oberdorf, Switzerland) without void filling. Forty-eight patients were reviewed between March and September 2014; 1 patient had died and 2 were lost to follow up. RESULTS: The mean HKA angle went from 172+/-3.18 degrees (165-178 degrees ) preoperatively to 181+/-1.18 degrees (176-185 degrees ) postoperatively, to 181+/-1.60 degrees (176-185 degrees ) at 2years, and 180.8+/-2.4 degrees (175 184 degrees ) at 10years' follow-up. This equates to a loss of correction of 0.71+/-1.9 degrees (0-6 degrees ) (p=0.02) between 2 and 10years after the surgery. Five patients underwent total knee arthroplasty (TKA), thus the 10-year survival of the HTO procedure was 88% (95% CI: 81-98%). If the five TKA procedures are excluded, the mean IKS knee score went from 90+/-7.4 (66-98) at 2years' follow-up to 77+/-15.3 (43-97) at 10years (p>0.05). There were four complications in all (8%), of which three occurred within 2years (2 cases of nonunion and 1 surgical site infection) and one occurred later (infection after 118months that resolved once the hardware was removed and the patient given appropriate antibiotics). There were no complications related to the five subsequent TKA procedure and no bone grafting was required. DISCUSSION: There was a small (less than 1 degree) but statistically significant loss of correction and non-significant deterioration in the functional outcomes. Conversely, the complication rate did not increase over time, despite the lack of void filling, particularly in patients who subsequently underwent TKA. The 10-year survival was similar to other HTO procedures. This locking plate construct without void filling is reliable after 10years. LEVEL OF EVIDENCE: Level IV, prospective study without control group. PMID- 29572181 TI - Urinary bladder organ hypertrophy is partially regulated by Akt1-mediated protein synthesis pathway. AB - AIMS: The present study aims to investigate the role of Akt in the regulation of urinary bladder organ hypertrophy caused by partial bladder outlet obstruction (pBOO). MAIN METHODS: Male rats were surgically induced for pBOO. Real-time PCR and western blot were used to examine the levels of mRNA and protein. A phosphoinositide 3-kinase (PI3K) inhibitor LY294002 was used to inhibit the activity of endogenous Akt. KEY FINDINGS: The urinary bladder developed hypertrophy at 2 weeks of pBOO. The protein but not mRNA levels of type I collagen and alpha-smooth muscle actin (alphaSMA) were increased in pBOO bladder when compared to sham control. The phosphorylation (activation) levels of Akt1 (p Ser473), mammalian target of rapamycin (mTOR), p70S6 kinase (p70S6K), and 4E-BP1 were also increased in pBOO bladder. LY294002 treatment reduced the phosphorylation levels of Akt1 and 4E-BP1, and the protein levels of type I collagen and alphaSMA in pBOO bladder. The mRNA and protein levels of proliferating cell nuclear antigen (PCNA) were increased in pBOO bladder, and PCNA up-regulation occurred in urothelial not muscular layer. LY294002 treatment had no effect on the mRNA and protein levels of PCNA in pBOO bladder. LY294002 treatment partially reduced the bladder weight caused by pBOO. SIGNIFICANCE: pBOO induced urinary bladder hypertrophy is attributable to fibrosis, smooth muscle cellular hypertrophy, and urothelium cell hyper-proliferation. Akt1-mediated protein synthesis in pBOO bladder contributes to type I collagen and alphaSMA but not PCNA up-regulation. Target of Akt1 is necessary but not sufficient in treatment of urinary bladder hypertrophy following pBOO. PMID- 29572183 TI - TNFAIP3 haploinsufficiency is the cause of autoinflammatory manifestations in a patient with a deletion of 13Mb on chromosome 6. AB - There is scarce literature about autoinflammation in syndromic patients. We describe a patient who, in addition to psychomotor and growth delay, presented with fevers, neutrophilic dermatosis, and recurrent orogenital ulcers. Comparative Genomic Hybridization (CGH) array permitted to identify a 13.13Mb deletion on chromosome 6, encompassing 53 genes, and including TNFAIP3 gene (A20). A20 is a potent inhibitor of the NF-kB signalling pathway and restricts inflammation via its deubiquitinase activity. Western blotting and immunoprecipitation assays showed decreased A20 expression and increased phosphorylation of p65 and IkBa. Patient's cells displayed increased levels of total K63-linked ubiquitin and increased levels of ubiquitinated RIP and NEMO after stimulation with TNF. We describe the molecular characterization of an autoinflammatory disease due to a large chromosomal deletion and review the phenotypes of patients with A20 haploinsufficiency. CGH arrays should be the first diagnostic method for comprehensive analysis of patients with syndromic features and immune dysregulation. PMID- 29572184 TI - Predictive utilities of neutrophil gelatinase-associated lipocalin (NGAL) in severe sepsis. AB - BACKGROUND: We aim to investigate the predictive value of plasma neutrophil gelatinase-associated lipocalin (pNGAL) in patients with severe sepsis. METHODS: A total of 124 patients were enrolled in this observational study. Blood samples were obtained at admission, on day 2 and day 7. Receiver operating characteristic (ROC) curves were generated to assess the utility of pNGAL in prediction of 28 day mortality and need for CRRT. Cox regression curves were built with and without pNGAL for 28-day mortality prediction to determine NGAL's contributive predictive value. RESULTS: Plasma NGAL was significantly increased in non survivors group on day 2 and 7 and predicted 28-day mortality with AuROC values of 0.675 (95% CI 0.570-0.780) and 0.752 (95% CI 0.619-0.885). Addition of day 2 NGAL to the clinical model resulted in a net reclassification index (NRI) increment of 0.40 (95% CI 0.06-0.75, P = 0.028) for prediction of 28-day mortality. The AuROC of NGAL at admission and day 2 was greater than creatinine in prediction of the need for CRRT. CONCLUSION: Plasma NGAL discriminated 28-day survivors from non-survivors on day 2 and 7 and was a relatively robust predictor of 28-day mortality prediction. Plasma NGAL possibly outperformed creatinine in the prediction of need for CRRT. PMID- 29572185 TI - C-reactive protein and emergency department seven days revisit. AB - BACKGROUND: Emergency department (ED) revisit might be partially preventable. C reactive protein (CRP) is an inflammatory biomarker which is commonly used as screening tool in the ED. We sought to evaluate the association between CRP level in patients visiting emergency department and 7 days revisit after discharge. METHODS: A historical cohort study of all patients who visited the internal division of the emergency department between June 2007 and July 2017 and had a CRP test. New ED visit was defined when neither any emergency department visit nor any hospital admission was recorded in our files during the previous 90 days. Univariate and multivariate models were used to evaluate the association between CRP and 7 days ED revisit. RESULTS: The study included 135,476 patients with 173,443 new visits. In 101,181 (58.3%) visits the patients were released and 7077 (7%) of them were revisited in 7 days. Even mild elevated CRP (5-25 mg/L) was independently associated with significant risk for revisit (OR 1.27, 95% CI 1.20 1.35). CONCLUSION: CRP is an independent predictor for 7 days ED revisit and should be considered at the time of discharge. Prediction models for ED revisit should include CRP as a potential predictor in their models. PMID- 29572187 TI - Joggin' the Noggin: Towards a Physiological Understanding of Exercise-Induced Cognitive Benefits. AB - This narrative review examines literature pertaining to possible physiological explanations for observed cognitive benefits stemming from improvements to cardiovascular fitness following chronic aerobic exercise. Studies regarding exercise and cardiovascular fitness, angiogenesis, neuroinflammation in relation to IGF-1 signalling, regulation of neurotrophins, neurogenesis and plasticity, cognitive training, are briefly described. We propose that current evidence points towards a mechanism by which cardiovascular fitness improvements act to promote long-term angiogenesis and cerebral circulation. This important adaptation allows for increased delivery and upregulation of neurotrophins along with supporting factors to the brain, particularly to the hippocampal neurogenic niche, following acute exercise bouts. We propose a sequential timeline and approximate time scale for this mechanism, describing how these stages generate increased support for neurogenesis and brain plasticity in combination with cognitive training to provide long-term cognitive benefits and protection against age-related cognitive decline. Influences from age, gender and other variables are considered, and methodological factors that could be utilised in future studies to further clarify the proposed model are discussed. PMID- 29572186 TI - Biomarker potential of IL-6 and VEGF-A in ascitic fluid of epithelial ovarian cancer patients. AB - BACKGROUND: Ovarian cancer is represented with significantly higher mortality rate predominately due to asymptomatic behaviour during initial disease course and at diagnosis majority patients already progressed to advanced stage. Acellular fraction of ascites in epithelial ovarian cancer (EOC) has been suggested to promote growth of tumor cells by providing ambient micro-environment for their proliferation. This acellular fraction contains multiple growth factors including IL-6 and VEGF-A, which were exploited to establish their bio-marker significance in EOC patients. METHODS: IL-6 and VEGF-A levels in ascitic fluid of 30 EOC patients and 15 controls were measured using high sensitivity sandwich enzyme linked immune sorbent (ELISA) assay. Their levels were correlated with clinico-pathological characteristics and bio-marker potential was assessed. RESULTS AND CONCLUSION: EOC patients showed significantly higher levels for IL-6 (median-5636 pg/ml) and VEGF-A (median-4556 pg/ml) in ascitic fluid compared to controls. Levels of IL-6 and VEGF-A significantly correlated with clinico pathological parameters. ROC curves of IL-6 and VEGF-A showed absolute combination of sensitivity and specificity. Kaplan Meier analysis demonstrated that higher levels of IL-6 and VEGF-A were significantly associated with shorter progression free survival. Thus, this study revealed that IL-6 and VEGF-A have great potential to be used as superior bio-markers for progression free survival in future after validation in larger patients' cohort. PMID- 29572188 TI - Long-term cognitive outcomes in male and female athletes following sport-related concussions. AB - Despite concussion being a serious public health concern and the increasing participation of female athletes in sport, the comparative long-term outcomes of male and female athletes are poorly understood, potentially limiting the scientific understanding and clinical management of these injuries. We examined whether sex influences the long-term cognitive outcomes in athletes with a history of concussion (HOC; 6+ months from injury). Accordingly, 196 asymptomatic student-athletes participated in the study (98 with a HOC; 98 matched controls). The sample included both male (n = 98) and female athletes (n = 98). Participants completed the Cogstate brief battery, to which we added a 2-Back condition to increase cognitive load. As predicted, the results revealed sex differences on the N-back Task, a measure of executive functions, with female athletes having a HOC responding significantly more slowly than their male counterparts on the 2 Back condition (p = 0.02). Moreover, irrespective of sex, athletes with a HOC were slower and less accurate relative to controls on the N-back Task (p = 0.01). Analyses failed to reveal any significant sex or group difference on tasks that measure lower-level cognition (ps > 0.05). The current results reaffirm the presence of subtle, yet long-term alterations in aspects of executive functions following a sport-related concussion. More importantly, our results highlight that female athletes exhibit alterations of greater magnitude than their male counterparts. Therefore, the sex difference observed in the days or weeks following a concussion may persist well into the chronic phase of injury. PMID- 29572189 TI - Inflammation-restricted anti-inflammatory activities of a N-acylethanolamine acid amidase (NAAA) inhibitor F215. AB - N-Acylethanolamine acid amidase (NAAA) is a cysteine enzyme that catalyzes the hydrolysis of palmitoylethanolamide (PEA). Pharmacological blockage of NAAA elevates PEA levels and exerts powerful anti-inflammatory activities. We have recently identified a highly potent NAAA inhibitor F215. Here, we demonstrated that F215 was an unusual inflammation-restricted NAAA inhibitor. In lipopolysaccharides (LPS) induced acute lung injury (ALI) model, F215 markedly accelerated inflammation resolution, promoted clearance of neutrophils infiltration and alveolar repair in the lungs. F215 efficiently inhibited NAAA and protected endogenous PEA from degradation in ALI model, but it cannot readily suppress the NAAA activity in naive mice. The inflammation-restricted effect of F215 was further confirmed in the alveolar macrophage, F215 only increased PEA levels and exerted anti-inflammatory effects in activated macrophages, but not in unstimulated macrophages. Moreover, we also showed that the pharmacological effects of F215 were restricted to the local inflamed skin elicited by 12-o tetradecanoylphorbol-13-acetate (TPA), but not the normal tissues. We believe that F215 could be a useful probe to investigate the function of NAAA, as well as a potent anti-inflammatory agent, and its inflammation-restricted feature might offer a new approach to prevent potential side effects of systemic enzyme inhibition. PMID- 29572191 TI - High Right Atrial Pressure and Low Pulse Pressure Predict Gastrointestinal Bleeding in Patients With Left Ventricular Assist Device. AB - BACKGROUND: Gastrointestinal bleeding (GIB) remains a major morbid event during continuous flow left ventricular assist device (LVAD) support. This study investigated whether a common hemodynamic profile is associated with GIB in patients with LVADs. METHODS AND RESULTS: A single institution analysis reviewed all patients who underwent right heart catheterization (RHC) following LVAD implant between January 1, 2006, and December 31, 2013, with follow-up through June 2015. Kaplan-Meier and multiphase hazard statistical methods were employed. Among 108 patients with 341 RHC, 55 hospitalizations for GIB occurred within 1 year of RHC. Freedom from GIB at 6 months was 92% in patients with pulse pressure >=35 mmHg, compared with 76% with pulse pressure <35 mmHg. By multivariable analysis, the significant predictors of GIB were: older age at implant, number of prior GIB, lower pulse pressure, lower mean arterial pressure, and higher right atrial pressure (all P < .05). The magnitude of effect is influenced by pulse pressure. CONCLUSIONS: Greater pulsatility and less venous congestion, along with other factors, are associated with a lower risk for GIB. It is reasonable to adjust therapeutic strategies to target this hemodynamic profile in patients with a propensity for GIB. PMID- 29572190 TI - Incident Hyperkalemia, Hypokalemia, and Clinical Outcomes During Spironolactone Treatment of Heart Failure With Preserved Ejection Fraction: Analysis of the TOPCAT Trial. AB - BACKGROUND: In patients with heart failure and preserved ejection fraction (HF PEF) randomized in the Americas as part of the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, treatment with spironolactone enhanced the risk of hyperkalemia but reduced the risk of hypokalemia. We examined the clinical correlates and prognostic implications of incident hypo- and hyperkalemia during study follow-up. METHODS: We defined the region-specific incidence of hypokalemia (potassium [K+] <3.5 mmol/l) and hyperkalemia (K+ >=5.5 mmol/l) among both placebo- and spironolactone-assigned patients in TOPCAT. Factors associated with incident hypokalemia and hyperkalemia and the relationship between incident K+ abnormalities and the risk of subsequent mortality were analyzed in multivariable regression models restricted to the Americas. RESULTS: In the Americas, assignment to spironolactone increased risk for hyperkalemia (hazard ratio 3.21, 95% confidence interval 2.46-4.20, P < .001) and reduced risk of hypokalemia (hazard ratio 0.43, 95% confidence interval 0.34 0.55, P < .001). Assignment to spironolactone, lower estimated glomerular filtration rate, higher baseline K+, diabetes, and lower hemoglobin were associated with incident hyperkalemia, whereas assignment to placebo, lower K+, younger age, lower estimated glomerular filtration rate, and use of diuretics at baseline were associated with hypokalemia. The combination of spironolactone and an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker was associated with incremental risk for hyperkalemia and protection from hypokalemia. Independent of region, both hypokalemia and hyperkalemia, were associated with higher risk for cardiovascular and all-cause mortality in multivariable-adjusted Cox regression models. CONCLUSIONS: Both hyperkalemia and hypokalemia are associated with heightened risk for mortality in HF-PEF. Use of spironolactone in this population requires careful laboratory surveillance of K+ and creatinine, particularly in high-risk groups.

AB - BACKGROUND: Solar urticaria (SU) is a rare photodermatosis causing a significant impact on patients' quality of life. Although the condition can be controlled with phototherapy and/or a combination therapy of antihistamines and leukotriene antagonist in most patients, a subset of patients require additional therapy with omalizumab; however, efficacy data are sparse. OBJECTIVE: The objective of this study was to determine the efficacy and safety of omalizumab for treating SU. METHODS: A case series of 5 patients with SU refractory to antihistamine and leukotriene antagonist combination who were treated with omalizumab is described. In addition, a systematic review of studies evaluating patients with SU treated with omalizumab was conducted. The primary outcome was partial/complete clinical response. Secondary outcomes were 10-fold decreases in the baseline minimal urticarial dose and adverse events. RESULTS: Our case series included 5 patients with SU. Monthly omalizumab doses of 150 to 600 mg resulted in clinical improvement in all patients and complete remission in 4. No adverse effects were reported. The systematic review included 22 studies (48 patients). All patients failed to control disease with antihistamines before omalizumab treatment. Patients received omalizumab at monthly doses of 150 to 750 mg over a follow-up period of 4 to 200 weeks. Thirty-eight patients (79%) experienced clinical improvement. Four patients (11%) had mild adverse effects. CONCLUSIONS: Omalizumab provided clinical benefits in approximately 80% of patients with SU. Patients failing to improve on standard omalizumab doses may benefit from higher monthly dosages. PMID- 29572193 TI - CD36 gene variants is associated with type 2 diabetes mellitus through the interaction of obesity in rural Chinese adults. AB - BACKGROUND: Evidences show that cluster determinant 36 (CD36) protein plays a role in lipid metabolism and insulin resistance, and the expression of CD36 is inducible in obesity. The present study evaluated the association of CD36 variants and the interaction with obesity on type 2 diabetes mellitus (T2DM) risk. METHODS: We performed a case-control study nested in the Rural Chinese Cohort Study. We included 546 incident T2DM cases matched with non-T2DM controls in a 1:1 ratio by sex, age (within 2 years), marital status, and residence village. Four loci in CD36 (rs1194197, rs2151916, rs3211956, and rs7755) were genotyped by SNPscanTM Genotyping system. RESULTS: After adjusting for potential confounding, we observed no statistically significant association between the CD36 polymorphisms and T2DM risk. Compared to wild-type homozygous carriers with normal weight, overweight/obesity participants carrying the mutational allele rs7755 showed increased risk of T2DM, by 114% (OR = 2.14, 95% CI: 1.33-3.46; Pinteraction = 0.007); abdominal obesity participants carrying the mutational allele rs7755 showed increased risk of T2DM, by 133% (OR = 2.33, 95% CI: 1.48 3.66; Pinteraction = 0.002). Furthermore, rs2151916 polymorphism was associated with triglycerides level (P = 0.019), and the rs1194197 variant was related to systolic blood pressure (P = 0.023) within the group of controls. CONCLUSIONS: CD36 genotypes were not associated with the progression to T2DM independently. However, our results suggested a positive interaction between the CD36 variants and obesity on T2DM susceptibility, which might be through a cardiometabolic disorder. PMID- 29572194 TI - Genetic differentiation and forensic efficiency evaluation for Chinese Salar ethnic minority based on a 5-dye multiplex insertion and deletion panel. AB - The present study investigated the genetic diversities of 30 autosomal insertion and deletion (InDel) loci of Investigator DIPplex kit (Qiagen) in Chinese Salar ethnic minority and explored the genetic relationships between the studied Salar group and other populations. The allelic frequencies of deletion alleles at the 30 InDel loci were in the range of 0.1739 (HLD64) to 0.8478 (HLD39). The discrimination power, polymorphism information content and probability of exclusion ranged from 0.4101 (HLD39) to 0.6447 (HLD136), 0.2247 (HLD39) to 0.3750 (HLD92) and 0.0400 (HLD39) to 0.2806 (HLD92), respectively. The observed and expected heterozygosity were in the range of 0.2348 (HLD39) to 0.5913 (HLD92), and 0.2580 (HLD39) to 0.5000 (HLD92), respectively. The cumulative discrimination power and probability of exclusion of the 30 loci reached 0.999999999993418 and 0.99039, respectively. The results of population genetic differentiation comparisons revealed that Salar group had similar allele distributions with Qinghai Tibetan, Xibe and Yi groups. Population Bayesian cluster analysis showed that there were similar ancestry components between Salar group and most Chinese populations. Besides, the principal components analysis and phylogenetic reconstructions further indicated that Salar group had intimate genetic relationships with Qinghai Tibetan and Xibe groups. In short, the results of the current studies indicated the genetic distributions of the 30 InDel loci in Salar group were relatively high genetic polymorphisms, which could be used in forensic individual identifications and as a supplementary tool for complex paternity testing. PMID- 29572195 TI - Biallelic UNC80 mutations caused infantile hypotonia with psychomotor retardation and characteristic facies 2 in two Chinese patients with variable phenotypes. AB - Biallelic UNC80 mutations cause infantile hypotonia with psychomotor retardation and characteristic facies 2 (IHPRF2), which is characterized by hypotonia, developmental delay (DD)/intellectual disability (ID), intrauterine growth retardation, postnatal growth retardation and characteristic facial features. We report two unrelated Chinese patients with compound heterozygous UNC80 mutations inherited from their parents, as identified by whole-exome sequencing (WES). Mutations c.3719G>A (p.W1240*)/c.4926_4937del (p.N1643_L1646del) and c.4963C>T (p.R1655C)/c.8385C>G (p.Y2795*) were identified in patient 1 and patient 2, respectively. Although both patients presented with DD/ID and hypotonia, different manifestations also occurred. Patient 1 presented with infantile hypotonia, epilepsy and hyperactivity without growth retardation, whereas patient 2 presented with persistent hypotonia, growth retardation and self-injury without epilepsy. Furthermore, we herein summarize the genotypes and phenotypes of patients with UNC80 mutations reported in the literature, revealing that IHPRF2 is a phenotypically heterogeneous disease. Common facial dysmorphisms include a thin upper lip, a tented upper lip, a triangular face, strabismus and microcephaly. To some extent, the manifestations of IHPRF2 mimic those of Angelman syndrome (AS)-like syndromes. PMID- 29572196 TI - Familial Hypertrophic Cardiomyopathy - Identification of cause and risk stratification through exome sequencing. AB - BACKGROUND: Hypertrophic Cardiomyopathy (HCM) with variable clinical presentations and heterogeneity is the common cause of sudden cardiac death. Genetic diagnosis is challenging in these complex diseases but exome sequencing as a genetic diagnostic tool provides explainable results. METHODS: In a familial Hypertrophic Cardiomyopathy with multigenerational inheritance with apparent phenotype, had a history of sudden death and severe arrhythmia followed by implantation of Implantable cardioverter defibrillator (ICD). Exome sequencing (100*) trailed by effective filtering steps for exome variants on the basis of different parameters, segregated variants are prioritized for the disease and further clinical relevance are evaluated for the variants. RESULTS: A rare causal variant in troponin-T gene (TNNT2, NM_000364.3;c.274C > T;p.Arg92Trp) is identified, shared by only affected members, absent in unaffected members and also in 200 unrelated control chromosomes. TNNT2 mutation act as a driver mutation but mutations in other disease-related genes, KCNMB1, LPL, APOE and other biochemical factors provides risk stratification within affected family members. CONCLUSION: This study contributes to the role of "rare variants" in complex disease phenotypes and heterogeneity within family and the necessity of whole exome targeted approaches in complex cardiomyopathy, which are known to harbor private mutations.

PMID- 29572197 TI - NOD2 expression, DNA damage and oxido-inflammatory status in atopic bronchial asthma: Exploring their nexus to disease severity. AB - BACKGROUND: Allergic asthma is a chronically relapsing inflammatory airway disease with a complex pathophysiology. AIM: This study was undertaken to investigate the potential contribution of NOD2 signaling, proinflammatory cytokines, chitotriosidase (CHIT1) activity, oxidative stress and DNA damage to atopic asthma pathogenesis, as well as to explore their possible role as surrogate noninvasive biomarkers for monitoring asthma severity. METHODS: Sixty patients with atopic bronchial asthma who were divided according to asthma severity into 40 mild-moderate, 20 severe atopic asthmatics, in addition to thirty age-matched healthy controls were enrolled in this study. NOD2 expression in PBMCs was assessed by quantitative real-time RT-PCR. DNA damage indices were assessed by alkaline comet assay. Serum IgE, IL-17, IL-8 and 3-Nitrotyrosine levels were estimated by ELISA. Serum CHIT1and GST activities, as well as MDA levels, were measured. RESULTS: NOD2 mRNA relative expression levels were significantly decreased in atopic asthmatic cases relative to controls with lower values among severe atopic asthmatics. On the other hand, IL-17 and IL-8 serum levels, CHIT1 activity, DNA damage indices and oxidative stress markers were significantly increased in atopic asthmatic cases relative to controls with higher values among severe atopic asthmatics. The change in these parameters correlated significantly with the degree of decline in lung function. CONCLUSION: The interplay between NOD2 signaling, proinflammatory cytokines, CHIT1 activity, heightened oxidative stress and DNA damage orchestrates allergic airway inflammation and thus contributing to the pathogenesis of atopic asthma. These parameters qualified for measurement as part of new noninvasive biomarker panels for monitoring asthma severity. PMID- 29572199 TI - Assessing the Readability of Medical Documents: A Ranking Approach. AB - BACKGROUND: The use of electronic health record (EHR) systems with patient engagement capabilities, including viewing, downloading, and transmitting health information, has recently grown tremendously. However, using these resources to engage patients in managing their own health remains challenging due to the complex and technical nature of the EHR narratives. OBJECTIVE: Our objective was to develop a machine learning-based system to assess readability levels of complex documents such as EHR notes. METHODS: We collected difficulty ratings of EHR notes and Wikipedia articles using crowdsourcing from 90 readers. We built a supervised model to assess readability based on relative orders of text difficulty using both surface text features and word embeddings. We evaluated system performance using the Kendall coefficient of concordance against human ratings. RESULTS: Our system achieved significantly higher concordance (.734) with human annotators than did a baseline using the Flesch-Kincaid Grade Level, a widely adopted readability formula (.531). The improvement was also consistent across different disease topics. This method's concordance with an individual human user's ratings was also higher than the concordance between different human annotators (.658). CONCLUSIONS: We explored methods to automatically assess the readability levels of clinical narratives. Our ranking-based system using simple textual features and easy-to-learn word embeddings outperformed a widely used readability formula. Our ranking-based method can predict relative difficulties of medical documents. It is not constrained to a predefined set of readability levels, a common design in many machine learning-based systems. Furthermore, the feature set does not rely on complex processing of the documents. One potential application of our readability ranking is personalization, allowing patients to better accommodate their own background knowledge. PMID- 29572201 TI - Investigating the Impact of Hearing Aid Use and Auditory Training on Cognition, Depressive Symptoms, and Social Interaction in Adults With Hearing Loss: Protocol for a Crossover Trial. AB - BACKGROUND: Sensorineural hearing loss is the most common sensory deficit among older adults. Some of the psychosocial consequences of this condition include difficulty in understanding speech, depression, and social isolation. Studies have shown that older adults with hearing loss show some age-related cognitive decline. Hearing aids have been proven as successful interventions to alleviate sensorineural hearing loss. In addition to hearing aid use, the positive effects of auditory training-formal listening activities designed to optimize speech perception-are now being documented among adults with hearing loss who use hearing aids, especially new hearing aid users. Auditory training has also been shown to produce prolonged cognitive performance improvements. However, there is still little evidence to support the benefits of simultaneous hearing aid use and individualized face-to-face auditory training on cognitive performance in adults with hearing loss. OBJECTIVE: This study will investigate whether using hearing aids for the first time will improve the impact of individualized face-to-face auditory training on cognition, depression, and social interaction for adults with sensorineural hearing loss. The rationale for this study is based on the hypothesis that, in adults with sensorineural hearing loss, using hearing aids for the first time in combination with individualized face-to-face auditory training will be more effective for improving cognition, depressive symptoms, and social interaction rather than auditory training on its own. METHODS: This is a crossover trial targeting 40 men and women between 50 and 90 years of age with either mild or moderate symmetric sensorineural hearing loss. Consented, willing participants will be recruited from either an independent living accommodation or via a community database to undergo a 6-month intensive face-to-face auditory training program (active control). Participants will be assigned in random order to receive hearing aid (intervention) for either the first 3 or last 3 months of the 6-month auditory training program. Each participant will be tested at baseline, 3, and 6 months using a neuropsychological battery of computer-based cognitive assessments, together with a depression symptom instrument and a social interaction measure. The primary outcome will be cognitive performance with regard to spatial working memory. Secondary outcome measures include other cognition performance measures, depressive symptoms, social interaction, and hearing satisfaction. RESULTS: Data analysis is currently under way and the first results are expected to be submitted for publication in June 2018. CONCLUSIONS: Results from the study will inform strategies for aural rehabilitation, hearing aid delivery, and future hearing loss intervention trials.

PMID- 29572200 TI - Evaluating the Impact of Physical Activity Apps and Wearables: Interdisciplinary Review. AB - BACKGROUND: Although many smartphone apps and wearables have been designed to improve physical activity, their rapidly evolving nature and complexity present challenges for evaluating their impact. Traditional methodologies, such as randomized controlled trials (RCTs), can be slow. To keep pace with rapid technological development, evaluations of mobile health technologies must be efficient. Rapid alternative research designs have been proposed, and efficient in-app data collection methods, including in-device sensors and device-generated logs, are available. Along with effectiveness, it is important to measure engagement (ie, users' interaction and usage behavior) and acceptability (ie, users' subjective perceptions and experiences) to help explain how and why apps and wearables work. OBJECTIVES: This study aimed to (1) explore the extent to which evaluations of physical activity apps and wearables: employ rapid research designs; assess engagement, acceptability, as well as effectiveness; use efficient data collection methods; and (2) describe which dimensions of engagement and acceptability are assessed. METHOD: An interdisciplinary scoping review using 8 databases from health and computing sciences. Included studies measured physical activity, and evaluated physical activity apps or wearables that provided sensor-based feedback. Results were analyzed using descriptive numerical summaries, chi-square testing, and qualitative thematic analysis. RESULTS: A total of 1829 abstracts were screened, and 858 articles read in full. Of 111 included studies, 61 (55.0%) were published between 2015 and 2017. Most (55.0%, 61/111) were RCTs, and only 2 studies (1.8%) used rapid research designs: 1 single-case design and 1 multiphase optimization strategy. Other research designs included 23 (22.5%) repeated measures designs, 11 (9.9%) nonrandomized group designs, 10 (9.0%) case studies, and 4 (3.6%) observational studies. Less than one-third of the studies (32.0%, 35/111) investigated effectiveness, engagement, and acceptability together. To measure physical activity, most studies (90.1%, 101/111) employed sensors (either in-device [67.6%, 75/111] or external [23.4%, 26/111]). RCTs were more likely to employ external sensors (accelerometers: P=.005). Studies that assessed engagement (52.3%, 58/111) mostly used device-generated logs (91%, 53/58) to measure the frequency, depth, and length of engagement. Studies that assessed acceptability (57.7%, 64/111) most often used questionnaires (64%, 42/64) and/or qualitative methods (53%, 34/64) to explore appreciation, perceived effectiveness and usefulness, satisfaction, intention to continue use, and social acceptability. Some studies (14.4%, 16/111) assessed dimensions more closely related to usability (ie, burden of sensor wear and use, interface complexity, and perceived technical performance). CONCLUSIONS: The rapid increase of research into the impact of physical activity apps and wearables means that evaluation guidelines are urgently needed to promote efficiency through the use of rapid research designs, in-device sensors and user logs to assess effectiveness, engagement, and acceptability. Screening articles was time-consuming because reporting across health and computing sciences lacked standardization. Reporting guidelines are therefore needed to facilitate the synthesis of evidence across disciplines. PMID- 29572202 TI - Influence of Flavors on the Propagation of E-Cigarette-Related Information: Social Media Study. AB - BACKGROUND: Modeling the influence of e-cigarette flavors on information propagation could provide quantitative policy decision support concerning smoking initiation and contagion, as well as e-cigarette regulations. OBJECTIVE: The objective of this study was to characterize the influence of flavors on e cigarette-related information propagation on social media. METHODS: We collected a comprehensive dataset of e-cigarette-related discussions from public Pages on Facebook. We identified 11 categories of flavors based on commonly used categorizations. Each post's frequency of being shared served as a proxy measure of information propagation. We evaluated a set of regression models and chose the hurdle negative binomial model to characterize the influence of different flavors and nonflavor control variables on e-cigarette-related information propagation. RESULTS: We found that 5 flavors (sweet, dessert & bakery, fruits, herbs & spices, and tobacco) had significantly negative influences on e-cigarette-related information propagation, indicating the users' tendency not to share posts related to these flavors. We did not find a positive significance of any flavors, which is contradictory to previous research. In addition, we found that a set of nonflavor-related factors were associated with information propagation. CONCLUSIONS: Mentions of flavors in posts did not enhance the popularity of e cigarette-related information. Certain flavors could even have reduced the popularity of information, indicating users' lack of interest in flavors. Promoting e-cigarette-related information with mention of flavors is not an effective marketing approach. This study implies the potential concern of users about flavorings and suggests a need to regulate the use of flavorings in e cigarettes. PMID- 29572203 TI - General Practitioners' Attitudes Toward a Web-Based Mental Health Service for Adolescents: Implications for Service Design and Delivery. AB - BACKGROUND: Anxiety disorders and depression are prevalent among youth. General practitioners (GPs) are often the first point of professional contact for treating health problems in young people. A Web-based mental health service delivered in partnership with schools may facilitate increased access to psychological care among adolescents. However, for such a model to be implemented successfully, GPs' views need to be measured. OBJECTIVE: This study aimed to examine the needs and attitudes of GPs toward a Web-based mental health service for adolescents, and to identify the factors that may affect the provision of this type of service and likelihood of integration. Findings will inform the content and overall service design. METHODS: GPs were interviewed individually about the proposed Web-based service. Qualitative analysis of transcripts was performed using thematic coding. A short follow-up questionnaire was delivered to assess background characteristics, level of acceptability, and likelihood of integration of the Web-based mental health service. RESULTS: A total of 13 GPs participated in the interview and 11 completed a follow-up online questionnaire. Findings suggest strong support for the proposed Web-based mental health service. A wide range of factors were found to influence the likelihood of GPs integrating a Web-based service into their clinical practice. Coordinated collaboration with parents, students, school counselors, and other mental health care professionals were considered important by nearly all GPs. Confidence in Web-based care, noncompliance of adolescents and GPs, accessibility, privacy, and confidentiality were identified as potential barriers to adopting the proposed Web-based service. CONCLUSIONS: GPs were open to a proposed Web-based service for the monitoring and management of anxiety and depression in adolescents, provided that a collaborative approach to care is used, the feedback regarding the client is clear, and privacy and security provisions are assured. PMID- 29572204 TI - Rapid and Accurate Behavioral Health Diagnostic Screening: Initial Validation Study of a Web-Based, Self-Report Tool (the SAGE-SR). AB - BACKGROUND: The Structured Clinical Interview for DSM (SCID) is considered the gold standard assessment for accurate, reliable psychiatric diagnoses; however, because of its length, complexity, and training required, the SCID is rarely used outside of research. OBJECTIVE: This paper aims to describe the development and initial validation of a Web-based, self-report screening instrument (the Screening Assessment for Guiding Evaluation-Self-Report, SAGE-SR) based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and the SCID-5-Clinician Version (CV) intended to make accurate, broad-based behavioral health diagnostic screening more accessible within clinical care. METHODS: First, study staff drafted approximately 1200 self-report items representing individual granular symptoms in the diagnostic criteria for the 8 primary SCID-CV modules. An expert panel iteratively reviewed, critiqued, and revised items. The resulting items were iteratively administered and revised through 3 rounds of cognitive interviewing with community mental health center participants. In the first 2 rounds, the SCID was also administered to participants to directly compare their Likert self-report and SCID responses. A second expert panel evaluated the final pool of items from cognitive interviewing and criteria in the DSM-5 to construct the SAGE-SR, a computerized adaptive instrument that uses branching logic from a screener section to administer appropriate follow-up questions to refine the differential diagnoses. The SAGE-SR was administered to healthy controls and outpatient mental health clinic clients to assess test duration and test-retest reliability. Cutoff scores for screening into follow-up diagnostic sections and criteria for inclusion of diagnoses in the differential diagnosis were evaluated. RESULTS: The expert panel reduced the initial 1200 test items to 664 items that panel members agreed collectively represented the SCID items from the 8 targeted modules and DSM criteria for the covered diagnoses. These 664 items were iteratively submitted to 3 rounds of cognitive interviewing with 50 community mental health center participants; the expert panel reviewed session summaries and agreed on a final set of 661 clear and concise self-report items representing the desired criteria in the DSM-5. The SAGE-SR constructed from this item pool took an average of 14 min to complete in a nonclinical sample versus 24 min in a clinical sample. Responses to individual items can be combined to generate DSM criteria endorsements and differential diagnoses, as well as provide indices of individual symptom severity. Preliminary measures of test-retest reliability in a small, nonclinical sample were promising, with good to excellent reliability for screener items in 11 of 13 diagnostic screening modules (intraclass correlation coefficient [ICC] or kappa coefficients ranging from .60 to .90), with mania achieving fair test-retest reliability (ICC=.50) and other substance use endorsed too infrequently for analysis. CONCLUSIONS: The SAGE-SR is a computerized adaptive self-report instrument designed to provide rigorous differential diagnostic information to clinicians. PMID- 29572205 TI - Circulating Branched-Chain Amino Acids and Incident Cardiovascular Disease in a Prospective Cohort of US Women. AB - BACKGROUND: Circulating branched-chain amino acids (BCAAs; isoleucine, leucine, and valine) are strong predictors of type 2 diabetes mellitus (T2D), but their association with cardiovascular disease (CVD) is uncertain. We hypothesized that plasma BCAAs are positively associated with CVD risk and evaluated whether this was dependent on an intermediate diagnosis of T2D. METHODS: Participants in the Women's Health Study prospective cohort were eligible if free of CVD at baseline blood collection (n=27 041). Plasma metabolites were measured via nuclear magnetic resonance spectroscopy. Multivariable Cox regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for BCAAs with incident CVD (myocardial infarction, stroke, and coronary revascularization). RESULTS: We confirmed 2207 CVD events over a mean 18.6 years of follow-up. Adjusting for age, body mass index, and other established CVD risk factors, total BCAAs were positively associated with CVD (per SD: HR, 1.13; 95% CI, 1.08-1.18), comparable to LDL-C (low-density lipoprotein cholesterol) with CVD (per SD: HR, 1.12; 95% CI, 1.07-1.17). BCAAs were associated with coronary events (myocardial infarction: HR, 1.16; 95% CI, 1.06-1.26; revascularization: HR, 1.17; 95% CI, 1.11-1.25), and borderline significant association with stroke (HR, 1.07; 95% CI, 0.99-1.15). The BCAA-CVD association was greater (P interaction=0.036) among women who developed T2D before CVD (HR, 1.20; 95% CI, 1.08-1.32) versus women without T2D (HR, 1.08; 95% CI, 1.03-1.14). Adjusting for LDL-C, an established CVD risk factor, did not attenuate these findings; however, adjusting for HbA1c and insulin resistance eliminated the associations of BCAAs with CVD. CONCLUSIONS: Circulating plasma BCAAs were positively associated with incident CVD in women. Impaired BCAA metabolism may capture the long-term risk of the common cause underlying T2D and CVD. PMID- 29572206 TI - Roles of PAD4 and NETosis in Experimental Atherosclerosis and Arterial Injury: Implications for Superficial Erosion. AB - RATIONALE: Neutrophils likely contribute to the thrombotic complications of human atheromata. In particular, neutrophil extracellular traps (NETs) could exacerbate local inflammation and amplify and propagate arterial intimal injury and thrombosis. PAD4 (peptidyl arginine deiminase 4) participates in NET formation, but an understanding of this enzyme's role in atherothrombosis remains scant. OBJECTIVE: This study tested the hypothesis that PAD4 and NETs influence experimental atherogenesis and in processes implicated in superficial erosion, a form of plaque complication we previously associated with NETs. METHODS AND RESULTS: Bone marrow chimeric Ldlr deficient mice reconstituted with either wild type or PAD4-deficient cells underwent studies that assessed atheroma formation or procedures designed to probe mechanisms related to superficial erosion. PAD4 deficiency neither retarded fatty streak formation nor reduced plaque size or inflammation in bone marrow chimeric mice that consumed an atherogenic diet. In contrast, either a PAD4 deficiency in bone marrow-derived cells or administration of DNaseI to disrupt NETs decreased the extent of arterial intimal injury in mice with arterial lesions tailored to recapitulate characteristics of human atheroma complicated by erosion. CONCLUSIONS: These results indicate that PAD4 from bone marrow-derived cells and NETs do not influence chronic experimental atherogenesis, but participate causally in acute thrombotic complications of intimal lesions that recapitulate features of superficial erosion. PMID- 29572207 TI - Cross-talk between nitric oxide and calcium-calmodulin regulate ganoderic acid biosynthesis in Ganoderma lucidum under heat stress. AB - We previously reported that high temperature impacts ganoderic acid (GA) biosynthesis in Ganoderma lucidum (G. lucidum) via Ca2+ Therefore, to further understand the signal regulating network of the organism's response to heat stress (HS), we examined the role of nitric oxide (NO) under HS. After HS treatment, the NO level was significantly increased by 120% compared with that under the control conditions. The application of a NO scavenger resulted in a 25% increase in GA compared with that found in the sample treated only with HS. Additionally, application of a NO donor to increase NO resulted in a 30% lower GA content than that in the sample treated only with HS. These results show that the increase in NO alleviates HS-induced GA accumulation. Subsequently, we aimed to detect the effects of the interaction between NO and Ca2+ on GA biosynthesis under HS in G. lucidum Our pharmacological approaches revealed that the NO and Ca2+ signals promoted each other in response to HS. We further constructed the silenced strain of nitrate reductase (NR) and calmodulin (CaM), and the results are in good agreement with the silenced strain and pharmacological experiment. The cross-promotion between NO and Ca2+ signals is involved in the regulation of HS-induced GA biosynthesis in G. lucidum, and this finding is supported by studies with NRi and CaMi strains. However, Ca2+ may have a more direct and significant effects on the HS-induced GA increase than NO. These data indicate that NO functions in signaling and has a close relationship with Ca2+ in HS induced GA biosynthesis.IMPORTANCE HS is an important environmental stress affecting the growth and development of organisms. We previously reported that HS modulates GA biosynthesis in G. lucidum via Ca2+ However, the signal regulating network of the organism's response to HS has not yet been elucidated. In this study, we found that NO relieved HS-induced GA accumulation, and NO and Ca2+ could exert promoting effects on each other in response to HS. Further research on the effect of NO and Ca2+ on the production of GAs in response to HS indicated that Ca2+ has a notably more direct and significant effect on the HS-induced GA increase than NO. Our results improve our understanding of the mechanism of HS signal transduction in fungi. A greater understanding of the regulation of secondary metabolism in response to environmental stimuli will provide clues regarding the role of these products in fungal biology. PMID- 29572208 TI - Induction of Genes Encoding Plant Cell Wall-Degrading Carbohydrate-Active Enzymes by Lignocellulose-Derived Monosaccharides and Cellobiose in the White-Rot Fungus Dichomitus squalens. AB - Fungi can decompose plant biomass into small oligo- and monosaccharides to be used as carbon sources. Some of these small molecules may induce metabolic pathways and the production of extracellular enzymes targeted for degradation of plant cell wall polymers. Despite extensive studies in ascomycete fungi, little is known about the nature of inducers for the lignocellulolytic systems of basidiomycetes. In this study, we analyzed six sugars known to induce the expression of lignocellulolytic genes in ascomycetes for their role as inducers in the basidiomycete white-rot fungus Dichomitus squalens using a transcriptomic approach. This identified cellobiose and l-rhamnose as the main inducers of cellulolytic and pectinolytic genes, respectively, of D. squalens Our results also identified differences in gene expression patterns between dikaryotic and monokaryotic strains of D. squalens cultivated on plant biomass-derived monosaccharides and the disaccharide cellobiose. This suggests that despite conservation of the induction between these two genetic forms of D. squalens, the fine-tuning in the gene regulation of lignocellulose conversion is differently organized in these strains.IMPORTANCE Wood-decomposing basidiomycete fungi have a major role in the global carbon cycle and are promising candidates for lignocellulosic biorefinery applications. However, information on which components trigger enzyme production is currently lacking, which is crucial for the efficient use of these fungi in biotechnology. In this study, transcriptomes of the white-rot fungus Dichomitus squalens from plant biomass-derived monosaccharide and cellobiose cultures were studied to identify compounds that induce the expression of genes involved in plant biomass degradation.

AB - Lactic acid bacteria can carry multiple plasmids affecting their performance in dairy fermentations. The expression of plasmid-encoded genes and the activity of the corresponding proteins is severely affected by changes in the number of plasmid copies. We studied the impact of growth rate on dynamics of plasmid copy numbers at high growth rates in chemostat cultures and down to near-zero growth rates in retentostat cultures. Five plasmids of the dairy strain Lactococcus lactis FM03-V1 were selected which varied in size (3 to 39 kb), in replication mechanism (theta or rolling-circle) and in putative (dairy-associated) functions. Copy numbers ranged from 1.5 to 40.5 and the copy number of theta-type replicating plasmids were negatively correlated to the plasmid size. Despite the extremely wide range of growth rates (0.0003 h-1 to 0.6 h-1), copy numbers of the five plasmids were stable and only slightly increased at near-zero growth rates showing that the plasmid replication rate was strictly controlled. One low-copy number plasmid, carrying a large exopolysaccharide gene cluster, was segregationally unstable during retentostat cultivations reflected in complete loss of the plasmid in one of the retentostat cultures. The copy number of the five plasmids was also hardly affected by varying the pH value, nutrient limitation or presence of citrate (maximum 2.2-fold) signifying the stability in copy number of the plasmids.ImportanceLactococcus lactis is extensively used in starter cultures for dairy fermentations. Important traits for growth and survival of L. lactis in dairy fermentations are encoded by genes located on plasmids, such as genes involved in lactose and citrate metabolism, protein degradation and oligopeptide uptake and bacteriophage resistance. Because the number of plasmid copies could affect the expression of plasmid-encoded genes, it is important to know the factors that influence the plasmid copy numbers. We monitored plasmid copy numbers of L. lactis at near-zero growth rates, characteristic for cheese ripening. Moreover, we analysed the effect of pH, nutrient limitation and presence of citrate. This showed that plasmid copy numbers were stable giving insight into plasmid copy number dynamics in dairy fermentations. PMID- 29572210 TI - A Novel Glaesserella sp. Isolated from Pigs with Severe Respiratory Infections Has a Mosaic Genome with Virulence Factors Putatively Acquired by Horizontal Transfer. AB - An unknown member of the family Pasteurellaceae was repeatedly isolated from 20- to 24-week-old pigs with severe pulmonary lesions reared on the same farm in Victoria, Australia. The etiological diagnosis of the disease was inconclusive. The complete genome sequence analysis of one strain, 15-184, revealed some phylogenic proximity to Glaesserella (Haemophilus) parasuis, the cause of Glasser's disease. However, the sequences of the 16S rRNA and housekeeping genes, as well as the average nucleotide identity scores, differed from those of all other known species in the family Pasteurellaceae The protein content of 15-184 was composite, with 60% of coding sequences matching known G. parasuis products, while more than 20% had a closer relative in the genera Actinobacillus, Mannheimia, Pasteurella, and Bibersteinia Several putative virulence genes absent from G. parasuis but present in other Pasteurellaceae were also found, including the apxIII RTX toxin gene from Actinobacillus pleuropneumoniae, ABC transporters from Actinobacillus minor, and iron transporters from various species. Three prophages and one integrative conjugative element were present in the isolate. Horizontal gene transfers might explain the mosaic genomic structure and atypical metabolic and virulence characteristics of 15-184. This organism has not been assigned a taxonomic position in the family, but this study underlines the need for a large-scale epidemiological and clinical characterization of this novel pathogen in swine populations, as a genomic analysis suggests it could have a severe impact on pig health.IMPORTANCE Several species of Pasteurellaceae cause a range of significant diseases in pigs. A novel member of this family was recently isolated from Australian pigs suffering from severe respiratory infections. Comparative whole-genome analyses suggest that this bacterium represents a new species, which possesses a number of virulence genes horizontally acquired from a diverse range of other Pasteurellaceae While the possible contribution of other coinfecting noncultivable agents to the disease has not been ruled out in this study, the repertoire of virulence genes found in this organism may nevertheless explain some aspects of the associated pathology observed on the farm. The prevalence of this novel pathogen within pig populations is currently unknown. This finding is of particular importance for the pig industry, as this organism can have a serious impact on the health of these animals. PMID- 29572211 TI - Homologous Recombination in Core Genomes Facilitates Marine Bacterial Adaptation. AB - Acquisition of ecologically relevant genes is common among ocean bacteria, but whether it has a major impact on genome evolution in marine environments remains unknown. Here, we analyzed the core genomes of 16 phylogenetically diverse and ecologically relevant bacterioplankton lineages, each consisting of up to five genomes varying at the strain level. Statistical approaches identified from each lineage up to ~50 loci showing anomalously high divergence at synonymous sites, which is best explained by recombination with distantly related organisms. The enriched gene categories in these outlier loci match well with the characteristics previously identified as the key phenotypes of these lineages. Examples are antibiotic synthesis and detoxification in Phaeobacter inhibens, exopolysaccharide production in Alteromonas macleodii, hydrocarbon degradation in Marinobacter hydrocarbonoclasticus, and cold adaptation in Pseudoalteromonas haloplanktis Intriguingly, the outlier loci feature polysaccharide catabolism in Cellulophaga baltica but not in Cellulophaga lytica, consistent with their primary habitat preferences in macroalga and beach sands respectively. Likewise, analysis of Prochlorococcus showed that photosynthesis related genes listed in the outlier loci are only found in high-light adapted ecotype but not in the low light adapted ecotype. These observations strongly suggest that recombination with distant relatives is a key mechanism driving the ecological diversification among marine bacterial lineages.IMPORTANCE Acquisition of new metabolic genes has been known as an important mechanism driving bacterial evolution and adaptation in the ocean, but acquisition of novel alleles of existing genes and its potential ecological role has not been examined. Guided by population genetic theories, our genomic analysis showed that divergent allele acquisition is prevalent in phylogenetically diverse marine bacterial lineages and that the affected loci often encode metabolic functions that underlies the known ecological roles of the lineages under study.

PMID- 29572212 TI - The Autophagy Gene BcATG8 Regulates the Vegetative Differentiation and Pathogenicity of Botrytis cinerea. AB - Autophagy is a conserved degradation process that maintains intracellular homeostasis to ensure normal cell differentiation and development in eukaryotes. ATG8 is one of the key molecular components of the autophagy pathway. In this study, we identified and characterized BcATG8, a homologue of Saccharomyces cerevisiae (yeast) ATG8 in the necrotrophic plant pathogen Botrytis cinerea Yeast complementation experiments demonstrated that BcATG8 can functionally complement the defects of the yeast ATG8 null mutant. Direct physical interaction between BcAtg8 and BcAtg4 was detected in the yeast two-hybrid system. Subcellular localization assays showed that green fluorescent protein-tagged BcAtg8 (GFP BcAtg8) localized in the cytoplasm as preautophagosomal structures (PAS) under general conditions but mainly accumulated in the lumen of vacuoles in the case of autophagy induction. Deletion of BcATG8 (DeltaBcAtg8 mutant) blocked autophagy and significantly impaired mycelial growth, conidiation, sclerotial formation, and virulence. In addition, the conidia of the DeltaBcAtg8 mutant contained fewer lipid droplets (LDs), and quantitative real-time PCR (qRT-PCR) assays revealed that the basal expression levels of the LD metabolism-related genes in the mutant were significantly different from those in the wild-type (WT) strain. All of these phenotypic defects were restored by gene complementation. These results indicate that BcATG8 is essential for autophagy to regulate fungal development, pathogenesis, and lipid metabolism in B. cinereaIMPORTANCE The gray mold fungus Botrytis cinerea is an economically important plant pathogen with a broad host range. Although there are fungicides for its control, many classes of fungicides have failed due to its genetic plasticity. Exploring the fundamental biology of B. cinerea can provide the theoretical basis for sustainable and long-term disease management. Autophagy is an intracellular process for degradation and recycling of cytosolic materials in eukaryotes and is now known to be vital for fungal life. Here, we report studies of the biological role of the autophagy gene BcATG8 in B. cinerea The results suggest that autophagy plays a crucial role in vegetative differentiation and virulence of B. cinerea. PMID- 29572213 TI - Assessment of Passive Traps Combined with High-Throughput Sequencing To Study Airborne Fungal Communities. AB - Techniques based on high-throughput sequencing (HTS) of environmental DNA have provided a new way of studying fungal diversity. However, these techniques suffer from a number of methodological biases which may appear at any of the steps involved in a metabarcoding study. Air is one of the most important environments where fungi can be found, because it is the primary medium of dispersal for many species. Looking ahead to future developments, it was decided to test 20 protocols, including different passive spore traps, spore recovery procedures, DNA extraction kits, and barcode loci. HTS was performed with the Illumina MiSeq platform targeting two subloci of the fungal internal transcribed spacer. Multivariate analysis and generalized linear models showed that the type of passive spore trap, the spore recovery procedure, and the barcode all impact the description of fungal communities in terms of richness and diversity when assessed by HTS metabarcoding. In contrast, DNA extraction kits did not significantly impact these results. Although passive traps may be used to describe airborne fungal communities, a study using specific real-time PCR and a mock community showed that these kinds of traps are affected by environmental conditions that may induce losses of biological material, impacting diversity and community composition results.IMPORTANCE The advent of high-throughput sequencing (HTS) methods, such as those offered by next-generation sequencing (NGS) techniques, has opened a new era in the study of fungal diversity in different environmental substrates. In this study, we show that an assessment of the diversity of airborne fungal communities can reliably be achieved by the use of simple and robust passive spore traps. However, a comparison of sample processing protocols showed that several methodological biases may impact the results of fungal diversity when assessed by metabarcoding. Our data suggest that identifying these biases is of paramount importance to enable a correct identification and relative quantification of community members. PMID- 29572215 TI - Health-related quality of life in congenital heart disease surgery in children and young adults: a systematic review and meta-analysis. AB - BACKGROUND: As survival improves in the congenital heart disease (CHD) population, health-related quality of life (HRQOL) outcomes become increasingly important. While surgery improves survival, poor HRQOL occurs postoperatively and cardiac-related HRQOL outcomes are rarely reported. OBJECTIVE: To conduct a systematic review and meta-analyses of general and cardiac-related HRQOL in CHD surgical children and young adults. METHOD: Medline, CINAHL and EMBASE were searched. Quantitative designs with a minimum of 80% CHD surgical patients and mean age <=18 years compared with healthy controls were included in the review. Data were analysed in RevMan V.5.3 using a random effects model. OUTCOME MEASURES: General and cardiac-related HRQOL. RESULTS: Studies (n=20) were conducted in high-income countries and included 3808 patients plus 2951 parental reports of patients. HRQOL was worse in postoperative patients with CHD versus healthy controls in all domains with the largest difference seen for physical function (standard mean difference (SMD) of -0.56, 95% CI -0.82 to -0.30). Cardiac-related HRQOL was worse in complex compared with simple CHD with the largest SMD (-0.60, 95% CI -0.80 to -0.40) for symptoms. Heterogeneity ranged from 0% to 90%. CONCLUSIONS: CHD surgical patients have substantially worse HRQOL compared with age-matched healthy controls. Strategies should focus on improving HRQOL in this subgroup. Results may not be applicable to low/middle-income countries given the dearth of relevant research. PMID- 29572216 TI - Femoral bone lesions accompanying cat-scratch disease.

AB - OBJECTIVES: Children's exposure to racism via caregiver experience (vicarious racism) is associated with poorer health and development. However, the relationship with child healthcare utilisation is unknown. We aimed to investigate (1) the prevalence of vicarious racism by child ethnicity; (2) the association between caregiver experiences of racism and child healthcare utilisation; and (3) the contribution of caregiver socioeconomic position and psychological distress to this association. DESIGN: Cross-sectional analysis of two instances of the New Zealand Health Survey (2006/2007: n=4535 child-primary caregiver dyads; 2011/2012: n=4420 dyads). MAIN OUTCOME MEASURES: Children's unmet need for healthcare, reporting no usual medical centre and caregiver reported dissatisfaction with their child's medical centre. RESULTS: The prevalence of reporting 'any' experience of racism was higher among caregivers of indigenous Maori and Asian children (30.0% for both groups in 2006/2007) compared with European/Other children (14.4% in 2006/2007). Vicarious racism was independently associated with unmet need for child's healthcare (OR=2.30, 95% CI 1.65 to 3.20) and dissatisfaction with their child's medical centre (OR=2.00, 95% CI 1.26 to 3.16). Importantly, there was a dose-response relationship between the number of reported experiences of racism and child healthcare utilisation (eg, unmet need: 1 report of racism, OR=1.89, 95% CI 1.34 to 2.67; 2+ reports of racism, OR=3.06, 95% CI 1.27 to 7.37). Adjustment for caregiver psychological distress attenuated the association between caregiver experiences of racism and child healthcare utilisation. CONCLUSIONS: Vicarious racism is a serious health problem in New Zealand disproportionately affecting Maori and Asian children and significantly impacting children's healthcare utilisation. Tackling racism may be an important means of improving inequities in child healthcare utilisation. PMID- 29572222 TI - Neurocognitive outcomes in children following immersion: a long-term study. AB - OBJECTIVE: To investigate long-term neurocognitive outcomes after a near-drowning incident in children who were deemed neurologically intact on discharge from hospital. DESIGN: A prospective cohort study of near-drowning children. SETTING: 95 drowning and near-drowning admissions, 0-16 years of age, from January 2009 to December 2013, to The Children's Hospital at Westmead, Sydney, NSW, Australia. PARTICIPANTS: 23 children both met the criteria and had parental consent for the study. MAIN OUTCOME MEASURES: Identification of the long-term deficits in behaviour, executive function, motor skills, communicative skills and well-being over a 5-year period. Assessment was undertaken at 3-6 months, 1 year, 3 years and 5 years after near-drowning at clinic visits. Physical developmental screening and executive function screening were done using Behavior Rating Inventory of Executive Function-Preschool version (BRIEF-P) and BRIEF. RESULT: 95 drowning and near-drowning episodes occurred during the study period. 10 (11%) children died, 28 were admitted to the paediatric intensive care unit and 64 directly to a ward. 3 children died in emergency department, 7 children had severe neurological deficit on discharge from the hospital. 23 were subsequently recruited into the study; 5 (22%) of these children had abnormalities in behaviour and/or executive function at some during their follow-up. CONCLUSION: Children admitted to hospital following a near-drowning event warrant long-term follow-up to identify any subtle sequelae which might be amenable to intervention to ensure optimal patient outcome.

AB - Chronic inflammation is a feature of pancreatic cancer, but little is known about how immune cells or immune cell-related signals affect pancreatic cancer stemness and development. Our previous work showed that IL22/IL22RA1 plays a vital role in acute and chronic pancreatitis progression by mediating cross-talk between immune cells and acinar cells or stellate cells, respectively. Here, we find IL22RA1 is highly but heterogeneously expressed in pancreatic cancer cells, with high expression associated with poor prognosis of patients with pancreatic cancer. The IL22RA1hi population from pancreatic cancer harbored higher stemness potential and tumorigenicity. Notably, IL22 promoted pancreatic cancer stemness via IL22RA1/STAT3 signaling, establishing the mechanism of regulation of cancer stemness by microenvironmental factors. Moreover, STAT3 was indispensable for the maintenance of IL22RA1hi cells. Overall, these findings provide a therapeutic strategy for patients with PDAC with high expression of IL22RA1.Significance: IL22RA1/STAT3 signaling enhances stemness and tumorigenicity in pancreatic cancer.

AB - Androgen receptor (AR) plays a crucial role in the development and progression of prostate cancer. AR expression has also been reported in other solid tumors, including renal cell carcinoma (RCC), but its biological role here remains unclear. Through integrative analysis of a reverse phase protein array, we discovered increased expression of AR in an RCC patient-derived xenograft model of acquired resistance to the receptor tyrosine kinase inhibitor (RTKi) sunitinib. AR expression was increased in RCC cell lines with either acquired or intrinsic sunitinib resistance in vitro An AR signaling gene array profiler indicated elevated levels of AR target genes in sunitinib-resistant cells. Sunitinib-induced AR transcriptional activity was associated with increased phosphorylation of serine 81 (pS81) on AR. Additionally, AR overexpression resulted in acquired sunitinib resistance and the AR antagonist enzalutamide induced AR degradation and attenuated AR downstream activity in sunitinib resistant cells, also indicated by decreased secretion of human kallikrein 2. Enzalutamide-induced AR degradation was rescued by either proteasome inhibition or by knockdown of the AR ubiquitin ligase speckle-type POZ protein (SPOP). In vivo treatment with enzalutamide and sunitinib demonstrated that this combination efficiently induced tumor regression in a RCC model following acquired sunitinib resistance. Overall, our results suggest the potential role of AR as a target for therapeutic interventions, in combination with RTKi, to overcome drug resistance in RCC.Significance: These findings highlight the therapeutic potential of targeting the androgen receptor to overcome RCC resistance to receptor tyrosine kinase inhibitors.

AB - Genome-wide association studies have identified more than 90 susceptibility loci for breast cancer. However, the missing heritability is evident, and the contributions of coding variants to breast cancer susceptibility have not yet been systematically evaluated. Here, we present a large-scale whole-exome association study for breast cancer consisting of 24,162 individuals (10,055 cases and 14,107 controls). In addition to replicating known susceptibility loci (e.g., ESR1, FGFR2, and TOX3), we identify two novel missense variants in C21orf58 (rs13047478, Pmeta = 4.52 * 10-8) and ZNF526 (rs3810151, Pmeta = 7.60 * 10-9) and one new noncoding variant at 7q21.11 (P < 5 * 10-8). C21orf58 and ZNF526 possessed functional roles in the control of breast cancer cell growth, and the two coding variants were found to be the eQTL for several nearby genes. rs13047478 was significantly (P < 5.00 * 10-8) associated with the expression of genes MCM3AP and YBEY in breast mammary tissues. rs3810151 was found to be significantly associated with the expression of genes PAFAH1B3 (P = 8.39 * 10-8) and CNFN (P = 3.77 * 10-4) in human blood samples. C21orf58 and ZNF526, together with these eQTL genes, were differentially expressed in breast tumors versus normal breast. Our study reveals additional loci and novel genes for genetic predisposition to breast cancer and highlights a polygenic basis of disease development.Significance: Large-scale genetic screening identifies novel missense variants and a noncoding variant as predisposing factors for breast cancer.

AB - Mitochondria regulate cellular bioenergetics and redox states and influence multiple signaling pathways required for tumorigenesis. In this study, we determined that the mitochondrial translation elongation factor 4 (EF4) is a critical component of tumor progression. EF4 was ubiquitous in human tissues with localization to the mitochondria (mtEF4) and performed quality control on respiratory chain biogenesis. Knockout of mtEF4 induced respiratory chain complex defects and apoptosis, while its overexpression stimulated cancer development. In multiple cancers, expression of mtEF4 was increased in patient tumor tissues. These findings reveal that mtEF4 expression may promote tumorigenesis via an imbalance in the regulation of mitochondrial activities and subsequent variation of cellular redox. Thus, dysregulated mitochondrial translation may play a vital role in the etiology and development of diverse human cancers.Significance: Dysregulated mitochondrial translation drives tumor development and progression.

AB - The reversible transitions of cancer cells between epithelial and mesenchymal states comprise cellular and molecular processes essential for local tumor growth and respective dissemination. We report here that globoside glycosphingolipid (GSL) glycosyltransferase-encoding genes are elevated in epithelial cells and correlate with characteristic EMT signatures predictive of disease outcome. Depletion of globosides through CRISPR-Cas9-mediated deletion of the key enzyme A4GALT induces EMT, enhances chemoresistance, and increased CD24low/CD44high cells. The cholera toxin-induced mesenchymal-to-epithelial transition occurred only in cells with functional A4GALT. Cells undergoing EMT lost E-cadherin expression through epigenetic silencing at the promoter region of CDH1 However, in DeltaA4GALT cells, demethylation was able to rescue E-cadherin-mediated cell cell adhesion only in the presence of exogenous A4GALT. Overall, our data suggest another class of biomolecules vital for epithelial cancer cells and for maintaining cell integrity and function.Significance: This study highlights the essential role of glycosphingolipids in the maintenance of epithelial cancer cell properties.

PMID- 29572229 TI - The MDA-9/Syntenin/IGF1R/STAT3 Axis Directs Prostate Cancer Invasion. AB - Although prostate cancer is clinically manageable during several stages of progression, survival is severely compromised once cells invade and metastasize to distant organs. Comprehending the pathobiology of invasion is required for developing efficacious targeted therapies against metastasis. Based on bioinformatics data, we predicted an association of melanoma differentiation associated gene-9 [syntenin, or syndecan binding protein (SDCBP)] in prostate cancer progression. Using tissue samples from various Gleason stage prostate cancer patients with adjacent normal tissue, a series of normal prostate and prostate cancer cell lines (with differing tumorigenic/metastatic properties), mda-9/syntenin-manipulated variants (including loss-of-function and gain-of function cell lines), and CRISPR/Cas9 stable MDA-9/Syntenin knockout cells, we now confirm the relevance of and dependence on MDA-9/syntenin in prostate cancer invasion. MDA-9/Syntenin physically interacted with insulin-like growth factor-1 receptor following treatment with insulin-like growth factor binding protein-2 (IGFBP2), regulating downstream signaling processes that enabled STAT3 phosphorylation. This activation enhanced expression of MMP2 and MMP9, two established enzymes that positively regulate invasion. In addition, MDA 9/syntenin-mediated upregulation of proangiogenic factors including IGFBP2, IL6, IL8, and VEGFA also facilitated migration of prostate cancer cells. Collectively, our results draw attention to MDA-9/Syntenin as a positive regulator of prostate cancer metastasis, and the potential application of targeting this molecule to inhibit invasion and metastasis in prostate cancer and potentially other cancers.Significance: This study provides new mechanistic insight into the proinvasive role of MDA-9/Syntenin in prostate cancer and has potential for therapeutic application to prevent prostate cancer metastasis.

AB - We report that PTEN-deficient prostate cancer cells use macropinocytosis to survive and proliferate under nutrient stress. PTEN loss increased macropinocytosis only in the context of AMPK activation, revealing a general requirement for AMPK in macropinocytosis and a novel mechanism by which AMPK promotes survival under stress. In prostate cancer cells, albumin uptake did not require macropinocytosis, but necrotic cell debris proved a specific macropinocytic cargo. Isotopic labeling confirmed that macropinocytosed necrotic cell proteins fueled new protein synthesis in prostate cancer cells. Supplementation with necrotic debris, but not albumin, also maintained lipid stores, suggesting that macropinocytosis can supply nutrients other than amino acids. Nontransformed prostatic epithelial cells were not macropinocytic, but patient-derived prostate cancer organoids and xenografts and autochthonous prostate tumors all exhibited constitutive macropinocytosis, and blocking macropinocytosis limited prostate tumor growth. Macropinocytosis of extracellular material by prostate cancer cells is a previously unappreciated tumor microenvironment interaction that could be targeted therapeutically.Significance: As PTEN-deficient prostate cancer cells proliferate in low-nutrient environments by scavenging necrotic debris and extracellular protein via macropinocytosis, blocking macropinocytosis by inhibiting AMPK, RAC1, or PI3K may have therapeutic value, particularly in necrotic tumors and in combination with therapies that cause nutrient stress.

PMID- 29572237 TI - The desA and desB genes from Clostridium scindens ATCC 35704 encode steroid-17,20 desmolase. AB - Clostridium scindens is a gut microbe capable of removing the side-chain of cortisol, forming 11beta-hydro-xyandrostenedione. A cortisol-inducible operon (desABCD) was previously identified in C. scindens ATCC 35704 by RNA-Seq. The desC gene was shown to encode a cortisol 20alpha-hydroxysteroid dehydrogenase (20alpha-HSDH). The desD encodes a protein annotated as a member of the major facilitator family, predicted to function as a cortisol transporter. The desA and desB genes are annotated as N-terminal and C-terminal transketolases, respectively. We hypothesized that the DesAB forms a complex and has steroid 17,20-desmolase activity. We cloned the desA and desB genes from C. scindens ATCC 35704 in pETDuet for overexpression in Escherichia coli The purified recombinant DesAB was determined to be a 142 +/- 5.4 kDa heterotetramer. We developed an enzyme-linked continuous spectrophotometric assay to quantify steroid-17,20 desmolase. This was achieved by coupling DesAB-dependent formation of 11beta hydroxyandrostenedione with the NADPH-dependent reduction of the steroid 17-keto group by a recombinant 17beta-HSDH from the filamentous fungus, Cochliobolus lunatus The pH optimum for the coupled assay was 7.0 and kinetic constants using cortisol as substrate were Km of 4.96 +/- 0.57 uM and kcat of 0.87 +/- 0.076 min 1 Substrate-specificity studies revealed that rDesAB recognized substrates regardless of 11beta-hydroxylation, but had an absolute requirement for 17,21 dihydroxy 20-ketosteroids.

AB - The inflammatory lesion at the pancreatic islet in type 1 diabetes (T1D) contains a heterogeneous infiltrate of T cells. In human and mouse studies, a large majority (98 to 99%) of the cytotoxic CD8+ T cells (CTLs) within islets are not specific to any islet antigen and are thought to passively add to tissue damage. We show by intravital confocal microscopy the opposite, immune-regulatory function of this cohort of CTLs. Diabetes did not develop in mice with islets showing high levels of infiltration of non-islet-specific CTLs not recognizing local antigens. Accumulation of such CTLs resulted in lower activation and proliferation of islet-specific CTLs, leading them to enter a state of unresponsiveness due to limited access to antigens at the inflammatory lesion. This nonspecific suppression by nonautoreactive CTLs was recapitulated in a model of viral meningitis, may explain viral interference in autoimmunity, and provides insight into the regulation of organ-specific autoimmune responses.

In this report, we outline the use of a prospective integrative clinical sequencing trial (PEDS-MIONCOSEQ) in a patient with SCN and AML to help identify oncogenic targets for less toxic agents. Integrative sequencing identified two somatic cis mutations in the colony stimulating factor 3 receptor (CSF3R) gene, a p.T640N mutation in the transmembrane region and a p.Q768* truncation mutation in the cytoplasmic domain. A somatic mutation p.H105Y, in the runt homology domain (RHD) of runt-related transcription factor 1 (RUNX1), was also identified. In addition, sequencing discovered a unique in-frame EIF4A2-MECOM (MDS1 and ectopic viral integration site 1 complex) chromosomal translocation with high MECOM expression. His mutations in CSF3R served as potential targets for tyrosine kinase inhibition and therefore provided an avenue to avoid more harmful therapy. This study highlights the utility of integrative clinical sequencing in SCN patients who develop leukemia and outlines a strategy on how to approach these patients in a future clinical sequencing trial to improve historically poor outcomes. A thorough review of leukemia in SCN and the role of CSF3R mutations in oncologic therapy are provided to support a new strategy on how to approach MDS/AML in SCN.

PMID- 29572241 TI - Contact-dependent growth inhibition induces high levels of antibiotic-tolerant persister cells in clonal bacterial populations. AB - Bacterial populations can use bet-hedging strategies to cope with rapidly changing environments. One example is non-growing cells in clonal bacterial populations that are able to persist antibiotic treatment. Previous studies suggest that persisters arise in bacterial populations either stochastically through variation in levels of global signalling molecules between individual cells, or in response to various stresses. Here, we show that toxins used in contact-dependent growth inhibition (CDI) create persisters upon direct contact with cells lacking sufficient levels of CdiI immunity protein, which would otherwise bind to and neutralize toxin activity. CDI-mediated persisters form through a feedforward cycle where the toxic activity of the CdiA toxin increases cellular (p)ppGpp levels, which results in Lon-mediated degradation of the immunity protein and more free toxin. Thus, CDI systems mediate a population density-dependent bet-hedging strategy, where the fraction of non-growing cells is increased only when there are many cells of the same genotype. This may be one of the mechanisms of how CDI systems increase the fitness of their hosts. PMID- 29572243 TI - Fat nerves keep pain at bay. PMID- 29572244 TI - Endosome maturation factors Rabenosyn-5/VPS45 and caveolin-1 regulate ciliary membrane and polycystin-2 homeostasis. AB - Primary cilium structure and function relies on control of ciliary membrane homeostasis, regulated by membrane trafficking processes that deliver and retrieve ciliary components at the periciliary membrane. However, the molecular mechanisms controlling ciliary membrane establishment and maintenance, especially in relation to endocytosis, remain poorly understood. Here, using Caenorhabditis elegans, we describe closely linked functions for early endosome (EE) maturation factors RABS-5 (Rabenosyn-5) and VPS-45 (VPS45) in regulating cilium length and morphology, ciliary and periciliary membrane volume, and ciliary signalling related sensory behaviour. We demonstrate that RABS-5 and VPS-45 control periciliary vesicle number and levels of select EE/endocytic markers (WDFY-2, CAV 1) and the ciliopathy membrane receptor PKD-2 (polycystin-2). Moreover, we show that CAV-1 (caveolin-1) also controls PKD-2 ciliary levels and associated sensory behaviour. These data link RABS-5 and VPS-45 ciliary functions to the processing of periciliary-derived endocytic vesicles and regulation of ciliary membrane homeostasis. Our findings also provide insight into the regulation of PKD-2 ciliary levels via integrated endosomal sorting and CAV-1-mediated endocytosis. PMID- 29572245 TI - A Phase I Trial of the IGF-1R Antibody Ganitumab (AMG 479) in Combination with Everolimus (RAD001) and Panitumumab in Patients with Advanced Cancer. AB - PURPOSE: This study evaluated the maximum tolerated dose or recommended phase II dose (RPTD) and safety and tolerability of the ganitumab and everolimus doublet regimen followed by the ganitumab, everolimus, and panitumumab triplet regimen. MATERIALS AND METHODS: This was a standard 3 + 3 dose escalation trial. Doublet therapy consisted of ganitumab at 12 mg/kg every 2 weeks; doses of everolimus were adjusted according to dose-limiting toxicities (DLTs). Panitumumab at 4.8 mg/kg every 2 weeks was added to the RPTD of ganitumab and everolimus. DLTs were assessed in cycle 1; toxicity evaluation was closely monitored throughout treatment. Treatment continued until disease progression or undesirable toxicity. Pretreatment and on-treatment skin biopsies were collected to assess insulin-like growth factor 1 receptor and mammalian target of rapamycin (mTOR) target modulation. RESULTS: Forty-three subjects were enrolled. In the doublet regimen, two DLTs were observed in cohort 1, no DLTs in cohort -1, and one in cohort -1B. The triplet combination was discontinued because of unacceptable toxicity. Common adverse events were thrombocytopenia/neutropenia, skin rash, mucositis, fatigue, and hyperglycemia. In the doublet regimen, two patients with refractory non-small cell lung cancer (NSCLC) achieved prolonged complete responses ranging from 18 to >60 months; one treatment-naive patient with chondrosarcoma achieved prolonged stable disease >24 months. In dermal granulation tissue, the insulin-like growth factor receptor and mTOR pathways were potently and specifically inhibited by ganitumab and everolimus, respectively. CONCLUSION: The triplet regimen of ganitumab, everolimus, and panitumumab was associated with unacceptable toxicity. However, the doublet of ganitumab at 12 mg/kg every 2 weeks and everolimus five times weekly had an acceptable safety profile and demonstrated notable clinical activity in patients with refractory NSCLC and sarcoma. IMPLICATIONS FOR PRACTICE: This trial evaluated the maximum tolerated dose or recommended phase II dose and safety and tolerability of the ganitumab and everolimus doublet regimen followed by the ganitumab, everolimus, and panitumumab triplet regimen. Although the triplet regimen of ganitumab, everolimus, and panitumumab was associated with unacceptable toxicity, the doublet of ganitumab at 12 mg/kg every 2 weeks and everolimus at five times weekly had an acceptable safety profile and demonstrated notable clinical activity in patients with refractory non-small cell lung cancer and sarcoma.

PMID- 29572246 TI - Comparative Proteomics of Dying and Surviving Cancer Cells Improves the Identification of Drug Targets and Sheds Light on Cell Life/Death Decisions. AB - Chemotherapeutics cause the detachment and death of adherent cancer cells. When studying the proteome changes to determine the protein target and mechanism of action of anticancer drugs, the still-attached cells are normally used, whereas the detached cells are usually ignored. To test the hypothesis that proteomes of detached cells contain valuable information, we separately analyzed the proteomes of detached and attached HCT-116, A375, and RKO cells treated for 48 h with 5 fluorouracil, methotrexate and paclitaxel. Individually, the proteomic data on attached and detached cells had comparable performance in target and drug mechanism deconvolution, whereas the combined data significantly improved the target ranking for paclitaxel. Comparative analysis of attached versus detached proteomes provided further insight into cell life and death decision making. Six proteins consistently up- or downregulated in the detached versus attached cells regardless of the drug and cell type were discovered; their role in cell death/survival was tested by silencing them with siRNA. Knocking down USP11, CTTN, ACAA2, and EIF4H had anti-proliferative effects, affecting UHRF1 additionally sensitized the cells to the anticancer drugs, while knocking down RNF-40 increased cell survival against the treatments. Therefore, adding detached cells to the expression proteomics analysis of drug-treated cells can significantly increase the analytical value of the approach. The data have been deposited to the ProteomeXchange with identifier PXD007686. PMID- 29572248 TI - Improving medication adherence in patients with cardiovascular disease: a systematic review. AB - OBJECTIVE: To evaluate and compare the effect of interventions for improving adherence to medications for atherosclerotic cardiovascular disease (ASCVD) secondary prevention. METHODS: We extracted eligible trials from a 2014 Cochrane systematic review on adherence for any condition. We updated the search from CENTRAL, Medline, Embase, PsycINFO, CINAHL, Sociological Abstracts and trial registers through November 2016. Study reports needed to be from a randomised controlled trial, incorporate participants identified as having ASCVD and interventions aimed at improving adherence to medicines for secondary prevention of ASCVD and measure both adherence and a clinical outcome. Two reviewers independently determined the eligibility of studies, extracted data and conducted a narrative synthesis. RESULTS: We identified 17 trials (n=17 448 participants). Most trials had high risk of bias in at least one domain. The intervention group adherence rates ranged from 44%to99% and the comparator group adherence rates ranged from 13% to 96%. Three distinct interventions reported improvements in both adherence and clinical outcomes: short message service (65% vs 13% of participants with high adherence in the intervention vs control group), a fixed dose combination pill (86% vs 65% adherence, risk ratio of being adherent, 1.33; 95% CI 1.26 to 1.41) and a community health worker-based intervention (97% in the intervention group compared with 92% in the control group; OR=2.62, 95% CI 1.32 to 5.19). CONCLUSIONS: We identified three interventions that demonstrated improvements in adherence and clinical outcomes. Ongoing, longer-term trials will help determine whether short-term changes in adherence can be maintained and lead to differences in clinical events. PMID- 29572249 TI - Take home messages with cases from focused update on echocardiographic assessment of aortic stenosis. AB - Echocardiography plays an important role in the assessment of valvular aortic stenosis. Updated recommendations focusing on a stepwise approach to evaluating aortic stenosis have recently been published by the European Association of Cardiovascular Imaging and the American Society of Echocardiography. This review uses illustrative cases to demonstrate technical aspects of aortic stenosis assessment and use of the new proposed classification scheme for aortic stenosis. Key points from the updated recommendations reviewed in this paper are: (1) technical considerations and sources of error in measurement of peak velocity, mean aortic valve gradient and aortic valve area by continuity equation. (2) Application of flow status using indexed left ventricular stroke volume to distinguish patients with low gradients and a low calculated aortic valve area. (3) Use of low-dose dobutamine stress echocardiography in patients with low ejection fraction. (4) Application of the new classification scheme and review of algorithm use for echocardiographic evaluation of severe aortic stenosis. Improved understanding of how to handle unmatched variables and adopting an integrated approach to determine severity is central to guiding the clinician's management of aortic stenosis.

PMID- 29572252 TI - Functional and clinical relevance of novel mutations in a large cohort of patients with Cockayne syndrome. AB - BACKGROUND: Cockayne syndrome (CS) is a rare, autosomal recessive multisystem disorder characterised by prenatal or postnatal growth failure, progressive neurological dysfunction, ocular and skeletal abnormalities and premature ageing. About half of the patients with symptoms diagnostic for CS show cutaneous photosensitivity and an abnormal cellular response to UV light due to mutations in either the ERCC8/CSA or ERCC6/CSB gene. Studies performed thus far have failed to delineate clear genotype-phenotype relationships. We have carried out a four centre clinical, molecular and cellular analysis of 124 patients with CS. METHODS AND RESULTS: We assigned 39 patients to the ERCC8/CSA and 85 to the ERCC6/CSB genes. Most of the genetic variants were truncations. The missense variants were distributed non-randomly with concentrations in relatively short regions of the respective proteins. Our analyses revealed several hotspots and founder mutations in ERCC6/CSB. Although no unequivocal genotype-phenotype relationships could be made, patients were more likely to have severe clinical features if the mutation was downstream of the PiggyBac insertion in intron 5 of ERCC6/CSB than if it was upstream. Also a higher proportion of severely affected patients was found with mutations in ERCC6/CSB than in ERCC8/CSA. CONCLUSION: By identifying >70 novel homozygous or compound heterozygous genetic variants in 124 patients with CS with different disease severity and ethnic backgrounds, we considerably broaden the CSA and CSB mutation spectrum responsible for CS. Besides providing information relevant for diagnosis of and genetic counselling for this devastating disorder, this study improves the definition of the puzzling genotype-phenotype relationships in patients with CS. PMID- 29572253 TI - Inframe deletion of human ESPN is associated with deafness, vestibulopathy and vision impairment. AB - BACKGROUND: Usher syndrome (USH) is a neurosensory disorder characterised by deafness, variable vestibular areflexia and vision loss. The aim of the study was to identify the genetic defect in a Pakistani family (PKDF1051) segregating USH. METHODS: Genome-wide linkage analysis was performed by using an Illumina linkage array followed by Sanger and exome sequencing. Heterologous cells and mouse organ of Corti explant-based transfection assays were used for functional evaluations. Detailed clinical evaluations were performed to characterise the USH phenotype. RESULTS: Through homozygosity mapping, we genetically linked the USH phenotype segregating in family PKDF1051 to markers on chromosome 1p36.32-p36.22. The locus was designated USH1M. Using a combination of Sanger sequencing and exome sequencing, we identified a novel homozygous 18 base pair inframe deletion in ESPN. Variants of ESPN, encoding the actin-bundling protein espin, have been previously associated with deafness and vestibular areflexia in humans with no apparent visual deficits. Our functional studies in heterologous cells and in mouse organ of Corti explant cultures revealed that the six deleted residues in affected individuals of family PKDF1051 are essential for the actin bundling function of espin demonstrated by ultracentrifugation actin binding and bundling assays. Funduscopic examination of the affected individuals of family PKDF1051 revealed irregular retinal contour, temporal flecks and disc pallor in both eyes. ERG revealed diminished rod photoreceptor function among affected individuals. CONCLUSION: Our study uncovers an additional USH gene, assigns the USH1 phenotype to a variant of ESPN and provides a 12th molecular component to the USH proteome. PMID- 29572255 TI - Cardiac Sympathetic Denervation Can Predict the Wearing-off Phenomenon in Patients with Parkinson Disease. AB - Recent studies have suggested that preserved cardiac sympathetic denervation may be associated with a small motor burden in Parkinson disease (PD) and serve as a good marker, which is not associated with other nonmotor symptoms. We sought to investigate whether cardiac sympathetic denervation increases the risk of the early wearing-off phenomenon in PD. Methods: This hospital-based prospective study enrolled 266 de novo patients with PD who underwent 123I metaiodobenzylguanidine (123I-MIBG) scintigraphy on initial evaluation. The patients visited the outpatient clinic every 2-6 mo and were followed for a minimum of 18 mo from the time they began taking dopaminergic medication. Each patient was assessed for the wearing-off phenomenon on the basis of the clinical assessments and symptom diaries. Clinical events were analyzed from the date of evaluation by 123I-MIBG scintigraphy until the date of the first occurrence of the wearing-off phenomenon, or until the last follow-up date without wearing-off. Results: During a mean follow-up period of 30.4 +/- 14.8 mo, 71 patients developed wearing-off. The wearing-off phenomenon occurred more in patients with decreased 123I-MIBG uptake. A Cox regression analysis revealed that both low 123I MIBG uptake and early onset age significantly predicted the development of wearing-off. Conclusion: Our study suggests that a reduction in myocardial 123I MIBG uptake in PD patients may be associated with a subsequent increased risk for the wearing-off phenomenon. Findings strongly support that PD patients with normal cardiac sympathetic innervation might have less involvement of the midbrain dopaminergic circuitry and a concomitant reduced risk for motor complications, such as wearing-off. PMID- 29572254 TI - PARP-1-Targeted Radiotherapy in Mouse Models of Glioblastoma. AB - The DNA repair enzyme poly(ADP-ribose) polymerase 1 (PARP-1) is overexpressed in glioblastoma, with overall low expression in healthy brain tissue. Paired with the availability of specific small molecule inhibitors, PARP-1 is a near-ideal target to develop novel radiotherapeutics to induce DNA damage and apoptosis in cancer cells, while sparing healthy brain tissue. Methods: We synthesized an 131I labeled PARP-1 therapeutic and investigated its pharmacology in vitro and in vivo. A subcutaneous tumor model was used to quantify retention times and therapeutic efficacy. A potential clinical scenario, intratumoral convection enhanced delivery, was mimicked using an orthotopic glioblastoma model combined with an implanted osmotic pump system to study local administration of 131I-PARPi (PARPi is PARP inhibitor). Results:131I-PARPi is a 1(2H)-phthalazinone, similar in structure to the Food and Drug Administration-approved PARP inhibitor AZD 2281. In vitro studies have shown that 131I-PARPi and AZD-2281 share similar pharmacologic profiles. 131I-PARPi delivered 134.1 cGy/MBq intratumoral injected activity. Doses to nontarget tissues, including liver and kidney, were significantly lower. Radiation damage and cell death in treated tumors were shown by p53 activation in U87-MG cells transfected with a p53-bioluminescent reporter. Treated mice showed significantly longer survival than mice receiving vehicle (29 vs. 22 d, P < 0.005) in a subcutaneous model. Convection-enhanced delivery demonstrated efficient retention of 131I-PARPi in orthotopic brain tumors, while quickly clearing from healthy brain tissue. Conclusion: Our results demonstrate 131I-PARPi's high potential as a therapeutic and highlight PARP's relevance as a target for radionuclide therapy. Radiation plays an integral role in brain tumor therapy, and radiolabeled PARP therapeutics could ultimately lead to improvements in the standard of care. PMID- 29572256 TI - Preclinical Evaluation of Mesothelin-Specific Ligands for SPECT Imaging of Triple Negative Breast Cancer. AB - Mesothelin is a cell-surface glycoprotein restricted to mesothelial cells overexpressed in several types of cancer, including triple-negative breast cancer not responding to trastuzumab or hormone-based therapies. Mesothelin-targeting therapies are currently being developed. However, the identification of patients potentially eligible for such a therapeutic strategy remains challenging. The objective of this study was to perform the radiolabeling and preclinical evaluation of 99mTc-A1 and 99mTc-C6, two antimesothelin single-domain antibody (sdAb)-derived imaging agents. Methods: A1 and C6 were radiolabeled with 99mTc and evaluated in vitro on recombinant protein and cells, as well as in vivo in xenograft mouse models of the triple-negative breast cancer cell lines HCC70 (mesothelin-positive) and MDA-MB-231 (mesothelin-negative). Results: Both 99mTc A1 and 99mTc-C6 bound mesothelin with high affinity in vitro, with 99mTc-A1 affinity being 2.4-fold higher than that of 99mTc-C6 (dissociation constant, 43.9 +/- 4.0 vs. 107 +/- 16 nM, P < 0.05). 99mTc-A1 and 99mTc-C6 remained stable in vivo in murine blood (>80% at 2 h) and ex vivo in human blood (>90% at 6 h). In vivo 99mTc-A1 uptake (percentage injected dose) in HCC70 tumors was 5-fold higher than in MDA-MB-231 tumors and 1.5-fold higher than that of 99mTc-C6 (2.34% +/- 0.36% vs. 0.48% +/- 0.18% and 1.56% +/- 0.43%, respectively, P < 0.01) and resulted in elevated tumor-to-background ratios. In vivo competition experiments demonstrated the specificity of 99mTc-A1 uptake in HCC70 tumors. Conclusion: Mesothelin-positive tumors were successfully identified by SPECT using 99mTc-A1 and 99mTc-C6. Considering its superior characteristics, 99mTc-A1 was selected as the most suitable tool for further clinical translation.

AB - Reliable standards and criteria for somatostatin receptor (SSTR) PET are still lacking. We herein propose a structured reporting system on a 5-point scale for SSTR PET imaging, titled SSTR-RADS version 1.0, which might serve as a standardized assessment for both diagnosis and treatment planning in neuroendocrine tumors. SSTR-RADS could guide the imaging specialist in interpreting SSTR PET scans, facilitate communication with the referring clinician so that appropriate workup for equivocal findings is pursued, and serve as a reliable tool for patient selection for planned peptide receptor radionuclide therapy. PMID- 29572258 TI - Direct Imaging of Drug Distribution and Target Engagement of the PARP Inhibitor Rucaparib. AB - Poly(ADP-ribose)polymerase (PARP) inhibitors have emerged as potent antitumor drugs. Here, we describe the intrinsic fluorescence properties of the clinically approved PARP inhibitor rucaparib and its potential to directly measure drug distribution and target engagement-a critical factor for understanding drug action and improving efficacy. Methods: We characterized the photophysical properties of rucaparib and determined its quantum yield and lifetime. Using confocal microscopy and flow cytometry, we imaged the intracellular distribution of rucaparib and measured uptake and release kinetics. Results: Rucaparib has an excitation/emission maximum of 355/480 nm and a quantum yield of 0.3. In vitro time-lapse imaging showed accumulation in cell nuclei within seconds of administration. Nuclear rucaparib uptake increased with higher PARP1 expression, and we determined an intracellular half-life of 6.4 h. Conclusion: The label free, intrinsic fluorescence of rucaparib can be exploited to interrogate drug distribution and target binding, critical factors toward improving treatment efficacy and outcome. PMID- 29572259 TI - The cross-tissue metabolic response of abalone (Haliotis midae) to functional hypoxia. AB - Functional hypoxia is a stress condition caused by the abalone itself as a result of increased muscle activity, which generally necessitates the employment of anaerobic metabolism if the activity is sustained for prolonged periods. With that being said, abalone are highly reliant on anaerobic metabolism to provide partial compensation for energy production during oxygen-deprived episodes. However, current knowledge on the holistic metabolic response for energy metabolism during functional hypoxia, and the contribution of different metabolic pathways and various abalone tissues towards the overall accumulation of anaerobic end-products in abalone are scarce. Metabolomics analysis of adductor muscle, foot muscle, left gill, right gill, haemolymph and epipodial tissue samples indicated that South African abalone (Haliotis midae) subjected to functional hypoxia utilises predominantly anaerobic metabolism, and depends on all of the main metabolite classes (proteins, carbohydrates and lipids) for energy supply. Functional hypoxia caused increased levels of anaerobic end products: lactate, alanopine, tauropine, succinate and alanine. Also, elevation in arginine levels was detected, confirming that abalone use phosphoarginine to generate energy during functional hypoxia. Different tissues showed varied metabolic responses to hypoxia, with functional hypoxia showing excessive changes in the adductor muscle and gills. From this metabolomics investigation, it becomes evident that abalone are metabolically able to produce sufficient amounts of energy when functional hypoxia is experienced. Also, tissue interplay enables the adjustment of H. midae energy requirements as their metabolism shifts from aerobic to anaerobic respiration during functional hypoxia.This article has an associated First Person interview with the first author of the paper.

PMID- 29572260 TI - Identification and characterization of host proteins bound to dengue virus 3' UTR reveal an antiviral role for quaking proteins. AB - The four dengue viruses (DENV1-4) are rapidly reemerging infectious RNA viruses. These positive-strand viral genomes contain structured 3' untranslated regions (UTRs) that interact with various host RNA binding proteins (RBPs). These RBPs are functionally important in viral replication, pathogenesis, and defense against host immune mechanisms. Here, we combined RNA chromatography and quantitative mass spectrometry to identify proteins interacting with DENV1-4 3' UTRs. As expected, RBPs displayed distinct binding specificity. Among them, we focused on quaking (QKI) because of its preference for the DENV4 3' UTR (DENV 4/SG/06K2270DK1/2005). RNA immunoprecipitation experiments demonstrated that QKI interacted with DENV4 genomes in infected cells. Moreover, QKI depletion enhanced infectious particle production of DENV4. On the contrary, QKI did not interact with DENV2 3' UTR, and DENV2 replication was not affected consistently by QKI depletion. Next, we mapped the QKI interaction site and identified a QKI response element (QRE) in DENV4 3' UTR. Interestingly, removal of QRE from DENV4 3' UTR abolished this interaction and increased DENV4 viral particle production. Introduction of the QRE to DENV2 3' UTR led to QKI binding and reduced DENV2 infectious particle production. Finally, reporter assays suggest that QKI reduced translation efficiency of viral RNA. Our work describes a novel function of QKI in restricting viral replication. PMID- 29572261 TI - Clock-dependent chromatin topology modulates circadian transcription and behavior. AB - The circadian clock in animals orchestrates widespread oscillatory gene expression programs, which underlie 24-h rhythms in behavior and physiology. Several studies have shown the possible roles of transcription factors and chromatin marks in controlling cyclic gene expression. However, how daily active enhancers modulate rhythmic gene transcription in mammalian tissues is not known. Using circular chromosome conformation capture (4C) combined with sequencing (4C seq), we discovered oscillatory promoter-enhancer interactions along the 24-h cycle in the mouse liver and kidney. Rhythms in chromatin interactions were abolished in arrhythmic Bmal1 knockout mice. Deleting a contacted intronic enhancer element in the Cryptochrome 1 (Cry1) gene was sufficient to compromise the rhythmic chromatin contacts in tissues. Moreover, the deletion reduced the daily dynamics of Cry1 transcriptional burst frequency and, remarkably, shortened the circadian period of locomotor activity rhythms. Our results establish oscillating and clock-controlled promoter-enhancer looping as a regulatory layer underlying circadian transcription and behavior. PMID- 29572263 TI - Gender differences in the associations of body mass index, physical fitness and tobacco use with lower extremity musculoskeletal injuries among new US Army soldiers. AB - BACKGROUND: Musculoskeletal (MSK) injuries are a leading cause of morbidity among US Army soldiers, especially among women and the newly enlisted. While extremes of body mass index (BMI), low physical fitness and tobacco use have been identified as risk factors, no prior studies have determined the combined effects of these risk factors or tested for gender differences in the associations. METHODS: We conducted a retrospective cohort study utilising the Stanford Military Data Repository to study all enlisted soldier accessions to the US Army between January 2011 and January 2014, with follow-up through December 2014 (n=238 772). We used discrete-time logistic regression to test for associations between demographic, socioeconomic and health behaviour-related predictors and incident lower extremity injuries. We included interaction terms to test for gender differences. RESULTS: Among men, there were greater adjusted odds of injury among underweight (OR 1.27), overweight (OR 1.14) and obese soldiers (OR 1.54) (all p<0.001) relative to normal-weight soldiers. No statistically significant differences in the odds of injury on the basis of BMI were observed for female soldiers. Physical fitness was a significantly stronger predictor of injury for female as compared with male soldiers, while the association between tobacco use and injury was stronger for men (OR 1.47) than for women (OR 1.30) (p<0.001 for both). CONCLUSION: This is the largest known study to simultaneously assess important, modifiable musculoskeletal injury risk factors and to test for gender differences in these associations. These findings provide critical gender related nuances for clinicians and leaders seeking to reduce the risk of these problems.

PMID- 29572266 TI - Increase in fluoroscopic radiation dose in successive sessions of multistage Onyx embolization of brain arteriovenous malformations compared with the first session. AB - BACKGROUND AND PURPOSE: Onyx embolization is a treatment for brain arteriovenous malformations (AVMs). However, multistage embolization usually involves the presence of radiodense Onyx cast from the previous sessions, which may influence the fluoroscopic radiation dose. We compared the fluoroscopic dose between the initial and final embolization sessions. MATERIALS AND METHOD: From January 2014 to September 2016, 18 patients underwent multistage Onyx embolization (more than twice) for brain AVMs. The total fluoroscopic duration (minutes), dose-area product (DAP, Gy*cm2), and cumulative air kerma (CAK, mGy) of both the frontal and lateral planes were obtained. We compared the frontal and lateral fluoroscopic dose rates (dose/time) of the final embolization session with those of the initial session. The relationship between the injected Onyx volume and radiation dose was tested. RESULTS: The initial and final procedures on the frontal plane showed significantly different fluoroscopic dose rates (DAP: initial 0.668 Gy*cm2/min, final 0.848 Gy*cm2/min, P=0.02; CAK: initial 12.7 mGy/min, final 23.1 mGy/min, P=0.007). Those on the lateral plane also showed a similar pattern (DAP: initial 0.365 Gy*cm2/min, final 0.519 Gy*cm2/min, P=0.03; CAK: initial 6.2 mGy/min, final 12.9 mGy/min, P=0.01). The correlation between the cumulative Onyx volume (vials) and radiation dose ratio of both planes showed an increasing trend (rho 0.4325-0.7053; P=0.0011-0.0730). CONCLUSION: Owing to the automatic exposure control function during fluoroscopy, successive Onyx embolization procedures increase the fluoroscopic radiation dose in multistage brain AVM embolization because of the presence of radiodense Onyx mass. PMID- 29572265 TI - The Stereotactic Intracerebral Hemorrhage Underwater Blood Aspiration (SCUBA) technique for minimally invasive endoscopic intracerebral hemorrhage evacuation. AB - BACKGROUND: Endoscopic intracerebral hemorrhage (ICH) evacuation techniques have gained interest as a potential therapeutic option. However, the instrumentation and techniques employed are still being refined to optimize hemostasis and evacuation efficiency. OBJECTIVE: We describe the application of a specific endoscopic technique in the treatment of ICH called the Stereotactic Intracerebral Hemorrhage Underwater Blood Aspiration (SCUBA) technique. It differs from previously described minimally invasive ICH interventions in that it combines two separate neuroendoscopic strategies in two phases, the first under dry-field conditions and the second using a wet-field strategy. METHODS: All patients who underwent endoscopic ICH evacuation with the SCUBA technique from December 2015 to September 2017 were included. RESULTS: The SCUBA technique was performed in 47 patients. The average evacuation percentage was 88.2% (SD 20.8). Active bleeding identified to derive from a specific source was observed in 23 (48.9%) cases. Active bleeding was addressed with irrigation alone in five cases (10.6%) and required electrocautery in 18 cases (38.3%). Intraoperative bleeding occurred in 3 patients (6.4%) and postoperative bleeding occurred in a single case (2.1%). CONCLUSIONS: The SCUBA technique provides surgeons with a defined strategy for true endoscopic hematoma evacuation. In particular, the fluid-filled cavity in SCUBA Phase 2 has the potential to provide several advantages over the traditional air-filled strategy, including clear identification and cauterization of bleeding vessels and visualization of residual clot burden. Further investigation is necessary to compare this technique to others that are currently used. PMID- 29572267 TI - Long-term visual outcome in patients treated by flow diversion for carotid ophthalmic aneurysms. AB - BACKGROUND: Flow-diverter stents (FDSs) are an upgrade in the treatment of intracranial aneurysms. However, complications concerning covered branches have been reported, especially the ophthalmic artery (OA). The purpose of our study was to evaluate the long-term ophthalmic complication rate of carotid-ophthalmic aneurysms (COA) without visual pathways compression, treated by a FDS covering the OA by performing an exhaustive ophthalmic examination. MATERIAL AND METHODS: Retrospective analysis of a single-center database screening the patients treated from October 2009 to April 2015 for an intracranial aneurysm with a FDS. The patients treated for a non-compressive COA with coverage of the OA by the device were studied (n=30). Among these patients, 15 (50%) were excluded. The remaining 15 patients underwent a systematic and extensive ophthalmic examination at least 2 years after the stent placement by two ophthalmologists. RESULTS: Fifteen patients with 16 COAs treated with a FDS were included. Mean follow-up was 4.1+/ 2 years. Six patients (40%), presented ophthalmic complications, including three fugax amauroses (18.8%) and four significant visual field defects (25%). After comparing each eye's visual field's patients, we observed a significant difference between the eye on the FDS side compared with the contralateral eye, with a mean deviation of -1.58 dB versus -0.67 dB respectively (P=0.003). Visual acuity was preserved in all patients. CONCLUSION: Patients treated by FDS for COA have a good long-term clinical ophthalmic outcome. However, extensive ophthalmic examination shows a high percentage of minor ophthalmic modifications. Interventional neuroradiologists should be aware of these possible complications when choosing to treat these aneurysms with FDS. PMID- 29572268 TI - A transcription factor network represses CFTR gene expression in airway epithelial cells. AB - Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause the inherited disorder cystic fibrosis (CF). Lung disease is the major cause of CF morbidity, though CFTR expression levels are substantially lower in the airway epithelium than in pancreatic duct and intestinal epithelia, which also show compromised function in CF. Recently developed small molecule therapeutics for CF are highly successful for one specific CFTR mutation and have a positive impact on others. However, the low abundance of CFTR transcripts in the airway limits the opportunity for drugs to correct the defective substrate. Elucidation of the transcriptional mechanisms for the CFTR locus has largely focused on intragenic and intergenic tissue-specific enhancers and their activating trans-factors. Here, we investigate whether the low CFTR levels in the airway epithelium result from the recruitment of repressive proteins directly to the locus. Using an siRNA screen to deplete ~1500 transcription factors (TFs) and associated regulatory proteins in Calu-3 lung epithelial cells, we identified nearly 40 factors that upon depletion elevated CFTR mRNA levels more than 2-fold. A subset of these TFs was validated in primary human bronchial epithelial cells. Among the strongest repressors of airway expression of CFTR were Kruppel-like factor 5 and Ets homologous factor, both of which have pivotal roles in the airway epithelium. Depletion of these factors, which are both recruited to an airway-selective cis-regulatory element at -35 kb from the CFTR promoter, improved CFTR production and function, thus defining novel therapeutic targets for enhancement of CFTR.

AB - Few studies have assessed the impact of home ventilation in patients with myotonic dystrophy type 1 (DM1) and no specific recommendations are available. We assessed the survival associated with category of home ventilation adherence of patients with DM1 followed up at a home ventilation unit using a Cox proportional hazards model. 218 patients were included; those who refused or delayed their acceptance of non-invasive ventilation were at higher risk for severe events (invasive ventilation or death) (P=0.03). Risk of death was associated with orthopnoea (HR 2.37; 95% CI 1.17 to 4.80; P<0.02) and adherence category (100 to 90% vs >75%: HR 3.26; 95% CI 1.32 to 8.04; P<0.03). Failure to use home ventilation as prescribed may be associated with increased mortality in patients with DM1. PMID- 29572272 TI - Uric acid, lung function and COPD: a causal link is unlikely.

PMID- 29572277 TI - White matter abnormalities and cognition in patients with conflicting diagnoses and CSF profiles. AB - OBJECTIVE: To determine whether white matter changes influence progression of cognitive decline in individuals with clinically diagnosed Alzheimer disease (AD) and differing biomarker profiles. METHODS: Two hundred thirty-six individuals from the Alzheimer's Disease Neuroimaging Initiative database with clinical diagnoses of cognitively normal older adult (older controls [OCs]), mild cognitive impairment, and AD were studied. Support vector machine experiments were first performed to determine the utility of various biomarkers for classifying individuals by clinical diagnosis. General linear models were implemented to assess the relationships between CSF measures of beta-amyloid 1 42, phosphorylated tau181p, and MRI-based white matter signal abnormality (WMSA) volumes and cognitive decline. Analyses were performed across all patients as well as within subgroups of individuals that were defined by clinical cutoff points for both CSF measures. RESULTS: CSF biomarkers alone classified individuals with AD vs OCs with 82% accuracy, and the addition of WMSA did not enhance this. Both CSF biomarkers as well as WMSA volume significantly contributed to predicting cognitive decline in executive and memory domains when assessed across all 236 individuals. In individuals with pathologic levels of both CSF biomarkers, WMSA only significantly contributed to models of future executive function decline. In individuals with subpathologic CSF biomarker levels (levels similar to those in OC individuals), WMSA significantly contributed to prediction of memory decline and were the sole significant predictor of executive function decline. CONCLUSIONS: WMSA hold additional predictive power regarding cognitive progression in older individuals and are most effective as biomarkers in individuals who are cognitively impaired but do not fit the expected CSF biomarker profile of AD. PMID- 29572278 TI - IV steroids during long episodes of Kleine-Levin syndrome. AB - OBJECTIVE: To retrospectively compare the benefits (episode cessation) and risks of IV methylprednisolone (IV-MP) vs abstention during prolonged Kleine-Levin syndrome (KLS) episodes. METHODS: A total of 26 patients with KLS received 1 g/d IV-MP for 3 days during 1 to 6 episodes each (totaling 43 IV-MP sessions). The change of episode duration with IV-MP (vs previous episode duration) was compared with the change duration between 2 consecutive episodes in 48 untreated patients matched for age, sex, age at KLS onset, number of episodes, and disease duration (more treated than untreated patients had long episodes). RESULTS: Eleven patients (42.3%) had an episode that was at least 1 week shorter than the preceding one when they received IV-MP therapy, whereas shorter episodes were significantly less frequent (10.4%) in the untreated group. This benefit was more marked (65.5% responders, 12 fewer days in an episode vs 0 days in the untreated patients) when IV-MP was infused before the 10th day of the episode. Mild, transient adverse effects (insomnia, muscle pain, nervousness/restlessness, but no manic switching) were reported by 61.3% of patients. No specific responder profile was identified. CONCLUSION: In this open-labeled, naturalistic study, early IV-MP (following the protocol for multiple sclerosis relapses) had a good benefit/risk ratio during KLS episodes in patients with long episodes (with half of the patients having an early cessation of episodes). CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for patients with long episodes of KLS, IV steroids decrease the duration of KLS episodes.

AB - OBJECTIVES: To investigate the role of beta oscillations in urinary voiding and their association with lower urinary tract symptoms in Parkinson disease (PD). METHODS: We used surgically implanted deep brain stimulation electrodes to record local field potential signals from the subthalamic nucleus (STN) and globus pallidus interna (GPi) of patients with PD during urinary voiding. Five patients with STN electrodes and 5 patients with GPi electrodes were tested. We also explored correlations between beta oscillatory power and urinary symptoms assessed by the International Consultation on Incontinence Lower Urinary Tract Symptoms questionnaire. RESULTS: Beta suppression occurred during urinary voiding in the GPi (p < 0.05) but not the STN. Furthermore, the beta signal in the GPi during voiding correlated significantly with severity of incontinence and urinary frequency (p < 0.05). CONCLUSIONS: In this study, we have demonstrated that local field potentials can provide information about the neural control of the bladder. Our findings suggest that the GPi is implicated in the process of urinary voiding and that its mechanism of action is linked to signals in the beta frequency band. Moreover, our correlational analyses show that beta oscillations may be implicated more generally in the pathophysiology of lower urinary tract symptoms in PD. PMID- 29572281 TI - Biomarker-based analysis of preclinical progression in spinal and bulbar muscular atrophy. AB - OBJECTIVE: To identify a candidate biomarker reflecting biological changes during the preclinical progression of spinal and bulbar muscular atrophy (SBMA). METHODS: We analyzed longitudinal changes in biochemical parameters obtained during health examinations before and after the diagnosis of SBMA. We estimated trajectories of clinical markers across years from the onset of weakness using linear mixed models and compared these trajectories with those estimated for male healthy controls and patients with amyotrophic lateral sclerosis (ALS) and Parkinson disease (PD). Moreover, we examined the relationship between serum creatinine level and the onset of symptoms using Kaplan-Meier curves. RESULTS: Between October 2014 and October 2017, we enrolled 40 patients with genetically confirmed SBMA, 48 healthy controls, 25 patients with ALS, and 20 patients with PD. In patients with SBMA, we evaluated the patients' data for a period of 17.3 +/- 7.5 years, including 11.4 +/- 7.1 years of preclinical phase. Decreases in serum creatinine occurred >10 years before the onset. The mean serum creatinine concentration was 0.56 mg/dL at the onset of weakness in patients with SBMA compared to 0.88 +/- 0.10 mg/dL on final evaluation in healthy controls. Serum levels of alanine transaminase and aspartate transaminase showed tendencies to increase in preclinical SBMA. These preclinical changes of biomarkers were not observed in either ALS or PD. CONCLUSIONS: Our findings suggest that serum creatinine begins to decrease before the onset of clinical symptoms and is a biomarker for disease progression and the efficacy of therapeutics in preclinical SBMA. PMID- 29572282 TI - Memory decline accompanies subthreshold amyloid accumulation. AB - OBJECTIVE: Extensive cortical beta-amyloid (Abeta positivity) has been linked to cognitive decline, but the clinical significance of elevations in Abeta within the negative range is unknown. METHODS: We examined amyloid and cognitive trajectories (memory, executive function) in 142 cognitively normal older individuals enrolled in the Alzheimer's Disease Neuroimaging Initiative who were Abeta-negative at baseline and who had at least 2 [18F]-florbetapir PET scans over 3.9 +/- 1.4 years. We determined whether Abeta accumulation was associated with longitudinal changes in memory or executive function. RESULTS: Among baseline-negative individuals, florbetapir slope (mean annual increase 0.002 +/- 0.008 standardized uptake value ratio units/y) was not related to age, sex, education, APOE4 status, baseline memory or executive function, temporoparietal glucose metabolism, baseline hippocampal volume, or hippocampal volume change; but it was related to higher baseline cortical florbetapir, indicating that Abeta accumulation was ongoing at baseline in those who accumulated during the study. Over the course of follow-up, 13 individuals converted to florbetapir+ and 14 nearly nonoverlapping individuals converted to mild cognitive impairment or Alzheimer disease. Amyloid accumulation among baseline-negative individuals was associated with poorer longitudinal memory performance (p = 0.019), but it was not associated with changes in executive function. Reducing the sample to individuals with at least 3 timepoints to estimate the florbetapir slope strengthened the relationship further between florbetapir accumulation and memory decline (p = 0.007). CONCLUSIONS: Memory decline accompanies Abeta accumulation in otherwise healthy, Abeta-negative older adults. Amyloid increases within the negative range may represent the earliest detectable indication of pathology with domain-specific cognitive consequences. PMID- 29572283 TI - Cerebellar volume as an imaging marker of development in infants with tuberous sclerosis complex. AB - OBJECTIVE: In this cohort analysis, we studied 1-year-old infants with tuberous sclerosis complex (TSC), correlating volumes of cerebellar structures with neurodevelopmental measures. METHODS: We analyzed data from a prospective biomarker study in infants with TSC (ClinicalTrials.gov NCT01780441). We included participants aged 12 months with an identified mutation of TSC1 or TSC2. Using MRI segmentation performed with the PSTAPLE algorithm, we measured relative volumes (structure volume divided by intracranial contents volume) of the following structures: right/left cerebellar white matter, right/left cerebellar exterior, vermal lobules I-V, vermal lobules VI-VII, and vermal lobules VIII-X. We correlated relative volumes to Mullen Scales of Early Learning (MSEL) scores. RESULTS: There were 70 participants (mean age 1.03 [0.11] years): n = 11 had a TSC1 mutation; n = 59 had a TSC2 mutation. For patients with TSC2 mutation, for every percentage increase in total cerebellar volume, there was an approximate 10 point increase in MSEL composite score (beta = 10.47 [95% confidence interval 5.67, 15.27], p < 0.001). For patients with TSC1 mutation, the relationship between cerebellar volume and MSEL composite score was not statistically significant (beta = -10.88 [95% confidence interval -22.16, 0.41], p = 0.06). For patients with TSC2 mutation, there were positive slopes when regressing expressive language and visual reception skills with volumes of nearly all cerebellar structures (p <= 0.29); there were also positive slopes when regressing receptive language skills, gross motor skills, and fine motor skills with volumes of cerebellar right/left exterior (p <= 0.014). CONCLUSIONS: Cerebellar volume loss-perhaps reflecting Purkinje cell degeneration-may predict neurodevelopmental severity in patients with TSC2 mutations. PMID- 29572284 TI - Aminophylline for treatment of postdural puncture headache: A randomized clinical trial. AB - OBJECTIVE: To investigate the efficacy and safety of IV aminophylline for patients with postdural puncture headache (PDPH). METHODS: We randomly assigned patients to groups receiving either 250 mg IV aminophylline or a placebo within 3 hours of symptom onset once daily for 2 consecutive days. The primary endpoint was headache severity 8 hours after treatment. We assessed this using visual analog scale (VAS) scores taken from patients in a standing position. We also recorded posttreatment VAS score changes, Patient Global Impression of Change (PGIC) scores, and adverse events. We performed an intention-to-treat analysis. RESULTS: We enrolled 126 patients with PDPH at 5 centers in China (62 assigned to the aminophylline group and 64 to the placebo group). The median age was 37 years, and 96 (76.2%) patients were women. Compared to the placebo-treated patients, the aminophylline-treated patients had significantly lower mean VAS scores 8 hours after treatment (5.34 vs 2.98, p < 0.001) and were significantly more likely to report improvements on the PGIC (39.1% vs 72.6%, p < 0.01). This therapeutic effect was already evident at the 30-minute time point and persisted for 2 days. There was no significant difference in the incidence of adverse events (4.8% vs 1.6%, p = 0.589). CONCLUSIONS: IV aminophylline is an effective and safe early-stage treatment for patients with PDPH. CLINICALTRIALSGOV IDENTIFIER: NCT02522013. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for people with PDPH, IV aminophylline reduces headache severity.

PMID- 29572287 TI - Allergen-Specific Immunotherapy in the Treatment of Pediatric Asthma: A Systematic Review. AB - CONTEXT: Treatment options for allergic asthma include allergen avoidance, pharmacotherapy, and allergen immunotherapy. OBJECTIVES: Summarize and update current evidence for the efficacy and safety of subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) in pediatric allergic asthma. DATA SOURCES: PubMed, Embase, Cochrane Central Register of Controlled Trials (January 1, 2005, through May 8, 2017), ClinicalTrials.gov, and the US Food and Drug Administration Adverse Event Reporting System. We reevaluated trials from our 2013 systematic review. STUDY SELECTION: We included studies with children <=18 years of age in which researchers reported on prespecified outcomes and had an intervention arm receiving aeroallergen SCIT or SLIT. Only randomized controlled trials (RCTs) were included for efficacy. RCTs and non-RCTs were included for safety outcomes. DATA EXTRACTION: Two reviewers extracted data. We included 40 studies (17 SCIT trials, 11 SLIT trials, 8 non-RCTs for SCIT safety, and 4 non-RCTs for SLIT safety). RESULTS: We found moderate-strength evidence that SCIT reduces long-term asthma medication use. We found low-strength evidence that SCIT improves asthma related quality of life and forced expiratory volume in 1 second. There was also low-strength evidence that SLIT improves medication use and forced expiratory volume in 1 second. There was insufficient evidence on asthma symptoms and health care use. LIMITATIONS: There were no trials in which researchers evaluated asthma symptoms using a validated tool. Study characteristics and outcomes were reported heterogeneously. CONCLUSIONS: In children with allergic asthma, SCIT may reduce long-term asthma medication use. Local and systemic allergic reactions are common, but anaphylaxis is reported rarely. PMID- 29572286 TI - Add-On Antihypertensive Medications to Angiotensin-Aldosterone System Blockers in Diabetes: A Comparative Effectiveness Study. AB - BACKGROUND AND OBJECTIVES: In individuals with diabetes, the comparative effectiveness of add-on antihypertensive medications added to an angiotensin converting enzyme inhibitor or angiotensin II receptor blocker on the risk of significant kidney events is unknown. DESIGN, SETTING PARTICIPANTS, & MEASUREMENTS: We used an observational, multicenter cohort of 21,897 individuals with diabetes to compare individuals who added beta-blockers, dihydropyridine calcium channel blockers, loop diuretics, or thiazide diuretics to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers. We examined the hazard of significant kidney events, cardiovascular events, and death using Cox proportional hazard models with propensity score weighting. The composite significant kidney event end point was defined as the first occurrence of a >=30% decline in eGFR to an eGFR<60 ml/min per 1.73 m2, initiation of dialysis, or kidney transplant. The composite cardiovascular event end point was defined as the first occurrence of hospitalization for acute myocardial infarction, acute coronary syndrome, stroke, or congestive heart failure; coronary artery bypass grafting; or percutaneous coronary intervention, and it was only examined in those free of cardiovascular disease at baseline. RESULTS: Over a maximum of 5 years, there were 4707 significant kidney events, 1498 deaths, and 818 cardiovascular events. Compared with thiazide diuretics, hazard ratios for significant kidney events for beta-blockers, calcium channel blockers, and loop diuretics were 0.81 (95% confidence interval, 0.74 to 0.89), 0.67 (95% confidence interval, 0.58 to 0.78), and 1.19 (95% confidence interval, 1.00 to 1.41), respectively. Compared with thiazide diuretics, hazard ratios of mortality for beta-blockers, calcium channel blockers, and loop diuretics were 1.19 (95% confidence interval, 0.97 to 1.44), 0.73 (95% confidence interval, 0.52 to 1.03), and 1.67 (95% confidence interval, 1.31 to 2.13), respectively. Compared with thiazide diuretics, hazard ratios of cardiovascular events for beta-blockers, calcium channel blockers, and loop diuretics compared with thiazide diuretics were 1.65 (95% confidence interval, 1.39 to 1.96), 1.05 (95% confidence interval, 0.80 to 1.39), and 1.55 (95% confidence interval, 1.05 to 2.27), respectively. CONCLUSIONS: Compared with thiazide diuretics, calcium channel blockers were associated with a lower risk of significant kidney events and a similar risk of cardiovascular events. PMID- 29572288 TI - Incidence and Costs of Neonatal Abstinence Syndrome Among Infants With Medicaid: 2004-2014. AB - OBJECTIVES: To describe incidence, health care use, and cost trends for infants with neonatal abstinence syndrome (NAS) who are covered by Medicaid compared with other infants. METHODS: We used 2004-2014 hospital birth data from the National Inpatient Sample, a nationally representative sample of hospital discharges in the United States (N = 13 102 793). Characteristics and trends among births impacted by NAS were examined by using univariate statistics and logistic regression. RESULTS: Medicaid covered 73.7% of NAS-related births in 2004 (95% confidence interval [CI], 68.9%-77.9%) and 82.0% of NAS-related births in 2014 (95% CI, 80.5%-83.5%). Among infants covered by Medicaid, NAS incidence increased more than fivefold during our study period, from 2.8 per 1000 births (95% CI, 2.1 3.6) in 2004 to 14.4 per 1000 births (95% CI, 12.9-15.8) in 2014. Infants with NAS who were covered by Medicaid were significantly more likely to be transferred to another hospital and have a longer length of stay than infants without NAS who were enrolled in Medicaid or infants with NAS who were covered by private insurance. Adjusting for inflation, total hospital costs for NAS births that were covered by Medicaid increased from $65.4 million in 2004 to $462 million in 2014. The proportion of neonatal hospital costs due to NAS increased from 1.6% in 2004 to 6.7% in 2014 among births that were covered by Medicaid. CONCLUSIONS: The number of Medicaid-financed births that are impacted by NAS has risen substantially and totaled $462 million in hospital costs in 2014. Improving affordable health insurance coverage for low-income women before pregnancy would expand access to substance use disorder treatment and could reduce NAS-related morbidity and costs.

PMID- 29572291 TI - Impact of temporary methotrexate discontinuation for 2 weeks on immunogenicity of seasonal influenza vaccination in patients with rheumatoid arthritis: a randomised clinical trial. AB - OBJECTIVE: To determine whether a 2-week methotrexate (MTX) discontinuation after vaccination improves the efficacy of seasonal influenza vaccination in patients with rheumatoid arthritis (RA). METHODS: In this prospective randomised parallel group multicentre study, patients with RA on stable dose of MTX were randomly assigned at a ratio of 1:1 to continue MTX or to hold MTX for 2 weeks after 2016 2017 quadrivalent seasonal influenza vaccine containing H1N1, H3N2, B-Yamagata and B-Victoria. The primary outcome was frequency of satisfactory vaccine response, defined as greater than or equal to fourfold increase of haemagglutination inhibition (HI) antibody titre at 4 weeks after vaccination against >=2 of four vaccine strains. Secondary endpoints included seroprotection (ie, HI titre >=1:40) rate, fold change in antibody titres. RESULTS: The modified intention-to-treat population included 156 patients in the MTX-continue group and 160 patients in the MTX-hold group. More patients in MTX-hold group achieved satisfactory vaccine response than the MTX-continue group (75.5% vs 54.5%, p<0.001). Seroprotection rate was higher in the MTX-hold group than the MTX continue group for all four antigens (H1N1: difference 10.7%, 95% CI 2.0% to 19.3%; H3N2: difference 15.9%, 95% CI 5.9% to 26.0%; B-Yamagata: difference13.7%, 95% CI 5.2% to 22.4%; B-Victoria: difference 14.7%, 95% CI 4.5% to 25.0%). The MTX-hold group showed higher fold increase in their antibody titres against all four influenza antigens (all p<0.05). Change in disease activity was similar between groups. CONCLUSIONS: A temporary MTX discontinuation for 2 weeks after vaccination improves the immunogenicity of seasonal influenza vaccination in patients with RA without increasing RA disease activity. TRIAL REGISTRATION: NCT02897011. PMID- 29572293 TI - Prominent inter-scallop separations of the posterior leaflet of the mitral valve: an important cause of 'pathological' mitral regurgitation. AB - The 2012 World Heart Federation (WHF) criteria for echocardiographic diagnosis of rheumatic heart disease (RHD) identify that the finding of 'pathological' mitral regurgitation (MR) in a screened individual increases the likelihood of detecting underlying RHD. Cases of isolated "pathological MR are thus identified as 'borderline RHD'. A large-scale echocardiographic screening program (Echo in Africa) in South Africa has identified that inter-scallop separations of the posterior mitral valve leaflet (PMVL) can give rise to 'pathological' MR. The authors propose that this finding when associated with isolated 'pathological' MR is unrelated to the rheumatic disease process. In this case report, we present two examples of 'pathological' MR related to inter-scallop separation from the Echo in Africa image database. We provide additional screening tips to accurately identify this entity.

AB - Cancer genome sequencing has shown that driver genes can often be distinguished not only by the elevated mutation frequency but also by specific nucleotide positions that accumulate changes at a high rate. However, properties associated with a residue's potential to drive tumorigenesis when mutated have not yet been systematically investigated. Here, using a novel methodological approach, we identify and characterize a compendium of 180 hotspot residues within 160 human proteins which occur with a significant frequency and are likely to have functionally relevant impact. We find that such mutations (i) are more prominent in proteins that can exist in the on and off state, (ii) reflect the identity of a tumor of origin, and (iii) often localize within interfaces which mediate interactions with other proteins or ligands. Following, we further examine structural data for human protein complexes and identify a number of additional protein interfaces that accumulate cancer mutations at a high rate. Jointly, these analyses suggest that disruption and dysregulation of protein interactions can be instrumental in switching functions of cancer proteins and activating downstream changes.

PMID- 29572298 TI - Impact of a commercial order entry system on prescribing errors amenable to computerised decision support in the hospital setting: a prospective pre-post study. AB - BACKGROUND: In this UK study, we investigated the impact of computerised physician order entry (CPOE) and clinical decision support (CDS) implementation on the rate of 78 high-risk prescribing errors amenable to CDS. METHODS: We conducted a preintervention/postintervention study in three acute hospitals in England. A predefined list of prescribing errors was incorporated into an audit tool. At each site, approximately 4000 prescriptions were reviewed both pre-CPOE and 6 months post-CPOE implementation. The number of opportunities for error and the number of errors that occurred were collated. Error rates were then calculated and compared between periods, as well as by the level of CDS. RESULTS: The prescriptions of 1244 patients were audited pre-CPOE and 1178 post-CPOE implementation. A total of 28 526 prescriptions were reviewed, with 21 138 opportunities for error identified based on 78 defined errors. Across the three sites, for those prescriptions where opportunities for error were identified, the error rate was found to reduce significantly post-CPOE implementation, from 5.0% to 4.0% (P<0.001). CDS implementation by error type was found to differ significantly between sites, ranging from 0% to 88% across clinical contraindication, dose/frequency, drug interactions and other error types (P<0.001). Overall, 43/78 (55%) of the errors had some degree of CDS implemented in at least one of the hospitals. CONCLUSIONS: Implementation of CPOE with CDS was associated with clinically important reductions in the rate of high-risk prescribing errors. Given the pre-post design, these findings however need to be interpreted with caution. The occurrence of errors was found to be highly dependent on the level of restriction of CDS presented to the prescriber, with the effect that different configurations of the same CPOE system can produce very different results. PMID- 29572299 TI - Perceptions of rounding checklists in the intensive care unit: a qualitative study. AB - BACKGROUND: Rounding checklists are an increasingly common quality improvement tool in the intensive care unit (ICU). However, effectiveness studies have shown conflicting results. We sought to understand ICU providers' perceptions of checklists, as well as barriers and facilitators to effective utilisation of checklists during daily rounds. OBJECTIVES: To understand how ICU providers perceive rounding checklists and develop a framework for more effective rounding checklist implementation. METHODS: We performed a qualitative study in 32 ICUs within 14 hospitals in a large integrated health system in the USA. We used two complementary data collection methods: direct observation of daily rounds and semistructured interviews with ICU clinicians. Observations and interviews were thematically coded and primary themes were identified using a combined inductive and deductive approach. RESULTS: We conducted 89 interviews and performed 114 hours of observation. Among study ICUs, 12 used checklists and 20 did not. Participants described the purpose of rounding checklists as a daily reminder for evidence-based practices, a tool for increasing shared understanding of patient care across care providers and a way to increase the efficiency of rounds. Checklists were perceived as not helpful when viewed as overstandardising care and when they are not relevant to a particular ICU's needs. Strategies to improve checklist implementation include attention to the brevity and relevance of the checklist to the particular ICU, consistent use over time, and integration with daily work flow. CONCLUSION: Our results provide potential insights about why ICU rounding checklists frequently fail to improve outcomes and offer a framework for effective checklist implementation through greater feedback and accountability.

PMID- 29572300 TI - Speak up-related climate and its association with healthcare workers' speaking up and withholding voice behaviours: a cross-sectional survey in Switzerland. AB - OBJECTIVES: To determine frequencies of healthcare workers (HCWs) speak up related behaviours and the association of speak up-related safety climate with speaking up and withholding voice. DESIGN: Cross-sectional survey of doctors and nurses. Data were analysed using multilevel logistic regression models SETTING: 4 hospitals with a total of nine sites from the German, French and Italian speaking part of Switzerland. PARTICIPANTS: Survey data were collected from 979 nurses and doctors. MAIN OUTCOME MEASURES: Frequencies of perceived patient safety concerns, of withholding voice and of speaking up behaviour. Speak up-related climate measures included psychological safety, encouraging environment and resignation. RESULTS: Perceived patient safety concerns were frequent among doctors and nurses (between 62% and 80% reported at least one safety concern during the last 4 weeks depending on the single items). Withholding voice was reported by 19%-39% of HCWs. Speaking up was reported by more than half of HCWs (55%-76%). The frequency of perceived concerns during the last 4 weeks was positively associated with both speaking up (OR=2.7, p<0.001) and withholding voice (OR=1.6, p<0.001). An encouraging environment was related to higher speaking up frequency (OR=1.3, p=0.005) and lower withholding voice frequency (OR=0.82, p=0.006). Resignation was associated with withholding voice (OR=1.5, p<0.001). The variance in both voicing behaviours attributable to the hospital-site level was marginal. CONCLUSIONS: Our results strengthen the importance of a speak up-supportive safety climate for staff safety-related communication behaviours, specifically withholding voice. This study indicates that a poor climate, in particular high levels of resignation among HCWs, is linked to frequent 'silence' of HCWs but not inversely associated with frequent speaking up. Interventions addressing safety related voicing behaviours should discriminate between withholding voice and speaking up.

AB - PURPOSE: The efficient use of big data in order to provide better health at a lower cost is described. SUMMARY: As data become more usable and accessible in healthcare, organizations need to be prepared to use this information to positively impact patient care. In order to be successful, organizations need teams with expertise in informatics and data management that can build new infrastructure and restructure existing infrastructure to support quality and process improvements in real time, such as creating discrete data fields that can be easily retrieved and used to analyze and monitor care delivery. Organizations should use data to monitor performance (e.g., process metrics) as well as the health of their populations (e.g., clinical parameters and health outcomes). Data can be used to prevent hospitalizations, combat opioid abuse and misuse, improve antimicrobial stewardship, and reduce pharmaceutical spending. These examples also serve to highlight lessons learned to better use data to improve health. For example, data can inform and create efficiencies in care and engage and communicate with stakeholders early and often, and collaboration is necessary to have complete data. To truly transform care so that it is delivered in a way that is sustainable, responsible, and patient-centered, health systems need to act on these opportunities, invest in big data, and routinely use big data in the delivery of care. CONCLUSION: Using data efficiently has the potential to improve the care of our patients and lower cost. Despite early successes, barriers to implementation remain including data acquisition, integration, and usability. PMID- 29572312 TI - Creating organizational value by leveraging the multihospital pharmacy enterprise. AB - PURPOSE: The results of a survey of multihospital pharmacy leaders are summarized, and a road map for creating organizational value with the pharmacy enterprise is presented. SUMMARY: A survey was designed to evaluate the level of integration of pharmacy services across each system's multiple hospitals, determine the most commonly integrated services, determine whether value was quantified when services were integrated, collect common barriers for finding value through integration, and identify strategies for successfully overcoming these barriers. The comprehensive, 59-question survey was distributed electronically in September 2016 to the top pharmacy executive at approximately 160 multihospital systems located throughout the United States. Survey respondents indicated that health systems are taking a wide range of approaches to integrating services systemwide. Several themes emerged from the survey responses: (1) having a system-level pharmacy leader with solid-line reporting across the enterprise increased the likelihood of integrating pharmacy services effectively, (2) integration of pharmacy services across a multihospital system was unlikely to decrease the number of pharmacy full-time equivalents within the enterprise, and (3) significant opportunities exist for creating value for the multihospital health system with the pharmacy enterprise, particularly within 4 core areas: system-level drug formulary and clinical standardization initiatives, supply chain initiatives, electronic health record integration, and specialty and retail pharmacy services. CONCLUSION: Consistently demonstrating strong organizational leadership, entrepreneurialism, and the ability to create value for the organization will lead to the system-level pharmacy leader and the pharmacy enterprise being well-positioned to achieve positive outcomes for patients, payers, and the broader health system. PMID- 29572313 TI - Strategies for success in creating an effective multihospital health-system pharmacy and therapeutics committee. AB - PURPOSE: Lessons learned from the creation of a multihospital health-system formulary management and pharmacy and therapeutics (P&T) committee are described. SUMMARY: A health system can create and implement a multihospital system formulary and P&T committee to provide evidence-based medications for ideal healthcare. The formulary and P&T process should be multidisciplinary and include adequate representation from system hospitals. The aim of a system formulary and P&T committee is standardization; however, the system should allow flexibility for differences. Key points for a successful multihospital system formulary and P&T committee are patience, collaboration, resilience, and communication. When establishing a multihospital health-system formulary and P&T committee, the needs of individual hospitals are crucial. A designated member of the pharmacy department needs to centrally coordinate and manage formulary requests, medication reviews and monographs, meeting agendas and minutes, and a summary of decisions for implementation. It is imperative to create a timeline for formulary reviews to set expectations, as well as a process for formulary appeals. Collaboration across the various hospitals is critical for successful formulary standardization. When implementing a health-system P&T committee or standardizing a formulary system, it is important to be patient and give local sites time to make practice changes. Evidence-based data and rationale must be provided to all sites to support formulary changes. Finally, there must be multidisciplinary collaboration. CONCLUSION: There are several options for formulary structures and P&T committees in a health system. Potential strengths and barriers should be evaluated before selecting a formulary management process. PMID- 29572314 TI - Pharmacy informatics in multihospital health systems: Opportunities and challenges. AB - PURPOSE: Challenges and opportunities in managing pharmacy-related technology in a multihospital health system are reviewed. SUMMARY: With electronic medical record (EMR) implementations, pharmacy technology deployments, and increased numbers of hospitals merging into single health systems, opportunities and challenges for pharmacy informatics (PI) teams have grown. Pharmacy leaders must consider the implications of using technology in a multihospital health-system environment, as well as the impact of the health system's organizational structures on technology implementations and dedicated support teams. Common challenges in achieving EMR and other technology implementation and standardization initiatives in multihospital health systems include harmonization of practices across hospitals of various sizes and types and issues of platform compatibility and interoperability. PI teams must collaborate with information technology teams at the system level to identify practical strategies for making the best use of available resources to implement pharmacy automation and software to help pharmacists continue to provide safe and effective patient care. The organizational structures that affect informatics teams, pharmacy integration and standardization initiatives, formulary management practices, data management and analytics, and clinical decision support systems all must be areas of focus. CONCLUSION: An integrated pharmacy enterprise can be well positioned to leverage operational efficiencies gained from appropriate use of technology to enhance patient care. Careful attention must be paid to the manner in which these systems are designed, implemented, and managed in order to make the best use of the technological resources used by the health system. PMID- 29572315 TI - Development and innovation of system resources to optimize patient care. AB - PURPOSE: Various incremental and disruptive healthcare innovations that are occurring or may occur are discussed, with insights on how multihospital health systems can prepare for the future and optimize the continuity of patient care provided. SUMMARY: Innovation in patient care is occurring at an ever-increasing rate, and this is especially true relative to the transition of patients through the care continuum. Health systems must leverage their ability to standardize and develop electronic health record (EHR) systems and other infrastructure necessary to support patient care and optimize outcomes; examples include 3D printing of patient-specific medication dosage forms to enhance precision medicine, the use of drones for medication delivery, and the expansion of telehealth capabilities to improve patient access to the services of pharmacists and other healthcare team members. Disruptive innovations in pharmacy services and delivery will alter how medications are prescribed and delivered to patients now and in the future. Further, technology may also fundamentally alter how and where pharmacists and pharmacy technicians care for patients. This article explores the various innovations that are occurring and that will likely occur in the future, particularly as they apply to multihospital health systems and patient continuity of care. CONCLUSION: Pharmacy departments that anticipate and are prepared to adapt to incremental and disruptive innovations can demonstrate value in the multihospital health system through strategies such as optimizing the EHR, identifying telehealth opportunities, supporting infrastructure, and integrating services. PMID- 29572316 TI - Creating a learning organization to help meet the needs of multihospital health systems. AB - PURPOSE: The considerations that leaders of multihospital health systems must take into account in developing and implementing initiatives to build and maintain an exceptional pharmacy workforce are described. SUMMARY: Significant changes that require constant individual and organizational learning are occurring throughout healthcare and within the profession of pharmacy. These considerations include understanding why it is important to have a succession plan and determining what types of education and training are important to support that plan. Other considerations include strategies for leveraging learners, dealing with a large geographic footprint, adjusting training opportunities to accommodate the ever-evolving demands on pharmacy staffs in terms of skill mix, and determining ways to either budget for or internally develop content for staff development. All of these methods are critically important to ensuring an optimized workforce. Especially for large health systems operating multiple sites across large distances, the use of technology-enabled solutions to provide effective delivery of programming to multiple sites is critical. Commonly used tools include live webinars, live "telepresence" programs, prerecorded programming that is available through an on-demand repository, and computer-based training modules. A learning management system is helpful to assign and document completion of educational requirements, especially those related to regulatory requirements (e.g., controlled substances management, sterile and nonsterile compounding, competency assessment). CONCLUSION: Creating and sustaining an environment where all pharmacy caregivers feel invested in and connected to ongoing learning is a powerful motivator for performance, engagement, and retention. PMID- 29572317 TI - Designing organizational structures: Key thoughts for development. AB - PURPOSE: Current strategies and concepts to consider in developing a system-level organizational structure for the pharmacy enterprise are discussed. SUMMARY: There are many different ways to design an organizational structure for the pharmacy enterprise within a health system. The size of the organization, the number of states in which it operates, and the geographic spread and complexity of the pharmacy business lines should be among the key considerations in determining the optimal organizational and decision-making structures for the pharmacy enterprise. The structure needs to support incorporation of the pharmacy leadership (both system-level executives and local leaders) into all strategic planning and discussions at the hospital and health-system levels so that they can directly represent the pharmacy enterprise instead of relying on others to develop strategy on their behalf. It is important that leaders of all aspects of the pharmacy enterprise report through the system's top pharmacy executive, who should be a pharmacist and have a title consistent with those of other leaders reporting at the same organizational level (e.g., chief pharmacy officer). CONCLUSION: Pharmacy leaders need to be well positioned within an organization to advocate for the pharmacy enterprise and use all resources to the best of their ability. As the scope and complexity of pharmacy services grow, it is critical to ensure that leadership of the pharmacy enterprise is unified under a single pharmacy executive team.

PMID- 29572319 TI - Ossabaw Pigs With a PCSK9 Gain-of-Function Mutation Develop Accelerated Coronary Atherosclerotic Lesions: A Novel Model for Preclinical Studies. AB - BACKGROUND: Ossabaw pigs are unique miniature swine with genetic predisposition to develop metabolic syndrome and coronary atherosclerosis after extended periods receiving atherogenic diets. We have hypothesized that transgenic Ossabaw swine expressing chimp PCSK9 (proprotein convertase subtilisin-like/kexin type 9) containing the D374Y gain of function would develop familial hypercholesterolemia and coronary artery plaques more rapidly than Landrace swine with the same transgene. METHODS AND RESULTS: Ossabaw and Landrace PCSK9 gain-of-function founders were generated by Sleeping Beauty transposition and cloning. Histopathologic findings in the Ossabaw founder animal showed more advanced plaques and higher stenosis than in the Landrace founder, underscoring the Ossabaw genetic predisposition to atherosclerosis. We chose to further characterize the Ossabaw PCSK9 gain-of-function animals receiving standard or atherogenic diets in a 6-month longitudinal study using computed tomography, magnetic resonance (MR) imaging, intravascular ultrasound, and optical coherence tomography, followed by pathological analysis of atherosclerosis focused on the coronary arteries. The Ossabaw model was consistently hypercholesterolemic, with or without dietary challenge, and by 6 months had consistent and diffuse fibrofatty or fibroatheromatous plaques with necrosis, overlying fibrous caps, and calcification in up to 10% of coronary plaques. CONCLUSIONS: The Ossabaw PCSK9 gain-of-function model provides consistent and robust disease development in a time frame that is practical for use in preclinical therapeutic evaluation to drive innovation. Although no animal model perfectly mimics the human condition, this genetic large-animal model is a novel tool for testing therapeutic interventions in the context of developing and advanced coronary artery disease. PMID- 29572320 TI - Decreased cAMP Level and Decreased Downregulation of beta1-Adrenoceptor Expression in Therapeutic Hypothermia-Resuscitated Myocardium Are Associated With Improved Post-Resuscitation Myocardial Function. AB - BACKGROUND: Epinephrine administered during cardiopulmonary resuscitation (CPR) is associated with severe post-resuscitation myocardial dysfunction. We previously demonstrated that therapeutic hypothermia reduced the severity of post resuscitation myocardial dysfunction caused by epinephrine; however, the relationship between myocardial adrenoceptor expression and myocardial protective effects by hypothermia remains unclear. METHODS AND RESULTS: Rats weighing between 450 and 550 g were randomized into 5 groups: (1) normothermic placebo, (2) normothermic epinephrine, (3) hypothermic placebo, (4) hypothermic epinephrine, and (5) sham (not subject to cardiac arrest and resuscitation). Ventricular fibrillation was induced and untreated for 8 minutes for all other groups. Hypothermia was initiated coincident with the start of CPR and maintained at 33+/-0.2 degrees C for 4 hours. Placebo or epinephrine was administered 5 minutes after the start of CPR and 3 minutes before defibrillation. Post resuscitation ejection fraction was measured hourly for 4 hours then hearts were harvested. Epinephrine increased coronary perfusion pressure during CPR (27+/-6 mm Hg versus 21+/-2 mm Hg P<0.05). Post-resuscitation myocardial function was impaired in the normothermic epinephrine group compared with other groups. The concentration of myocardial cAMP doubled in the normothermic epinephrine group (655.06+/-447.63 MUmol/L) compared with the hypothermic epinephrine group (302.51+/-97.98 MUmol/L; P<0.05). Myocardial beta1-adrenoceptor expression decreased with normothermia cardiac arrest but not with hypothermia regardless of epinephrine. CONCLUSIONS: Epinephrine, administered during normothermic CPR, increased the severity of post-resuscitation myocardial dysfunction. This adverse effect was inhibited by intra-arrest hypothermia resuscitation. Declined cAMP with more preserved beta1-adrenoceptors in hypothermia-resuscitated myocardium is associated with improved post-resuscitated myocardial function in vivo. PMID- 29572321 TI - Ablation Outcomes and Predictors of Mortality Following Catheter Ablation for Ventricular Tachycardia: Data From the German Multicenter Ablation Registry. AB - BACKGROUND: Ventricular tachycardia (VT) causes significant morbidity and mortality. Implantable cardioverter-defibrillator shocks terminate VT but confer a significant morbidity and mortality risk. Therefore, VT ablation is increasingly common. Patients with structural heart disease (SHD) and patients with structurally normal hearts as well as the subgroup with and without ischemic heart disease were assessed for predictors of mortality and nonfatal VT recurrence. We present the first multicenter, prospective German VT registry. METHODS AND RESULTS: In 334 patients, 118 structurally normal hearts and 216 SHD (74.5% ischemic heart disease), referred for VT ablation in 38 centers, long-term follow-up was assessed for a minimum of 12 months and analyzed for factors predicting VT recurrence rates and mortality. The VTs in SHD patients were more frequently hemodynamically unstable (34.7% versus 12.7%, P<0.0001) or incessant (9.7% versus 2.7%, P<0.05). More SHD patients underwent substrate modification than patients with structurally normal hearts who had more focal ablations. Ablation failure was 9% in both groups. Two-year mortality was higher in patients with SHD (18.7% versus 3.5%, P<0.001). Predictors of mortality include age >60 years, incessant VT, left ventricular ejection fraction <=30%, procedural failure, and Class I and III anti-arrhythmic drug use at discharge. Only procedural failure is a predictor of nonfatal VT recurrence. CONCLUSIONS: Procedural failure was the sole independent predictor for nonfatal VT recurrence for our study cohort. This emphasizes the importance of a successful ablation procedure in experienced hands to reduce long-term mortality and nonfatal VT recurrence. PMID- 29572322 TI - Sp1 Plays an Important Role in Vascular Calcification Both In Vivo and In Vitro. AB - BACKGROUND: Vascular calcification and increased cardiovascular morbidity and mortality are closely related in patients with end-stage renal disease and diabetes mellitus. Specific protein 1 (Sp1) is a transactivation molecule that plays a crucial role in the regulation of apoptosis, fibrosis, angiogenesis, and other pathological disorders. There is evidence that specific protein 1 (Sp1) directly stimulates the transcription of bone morphogenetic protein 2 (BMP2) and that BMP2 plays a key role in the calcification process in the BMP2-expressing F9 cell model system. Here, we investigated whether Sp1 plays an important role in vascular calcification and its potential regulatory mechanism in vascular calcification. METHODS AND RESULTS: In this study, vascular calcification was induced in male Wistar rats by administration of nicotine (25 mg/kg) and vitamin D3 (300 000 IU/kg). These rats were randomly selected for treatment with adenovirus harboring Sp1 knockdown gene or empty virus. The mechanism of Sp1 in vascular smooth muscle cells cultured in high phosphate medium was studied. Based on our findings, the Sp1 gene silencing or inhibition improved calcium deposition, which was partly achieved by inhibiting phenotype switch, apoptosis, and matrix vesicle release of vascular smooth muscle cells. Moreover, Sp1 can activate BMP2 transcription by binding to the Sp1-binding element of the BMP2 promoter. CONCLUSIONS: Overall, elevated Sp1 exerts a pro-apoptotic effect, promoting BMP2 transcription and further accumulating vascular calcification. Proper and timely regulation of Sp1 expression may be a potential strategy for treatment of aging, end-stage renal disease, and diabetic-related macrovascular disease treatment. PMID- 29572323 TI - Evaluation of Collateral Source Characteristics With 3-Dimensional Analysis Using Micro-X-Ray Computed Tomography. AB - BACKGROUND: Collateral arteries provide an alternative blood supply and protect tissues from ischemic damage in patients with peripheral artery disease. However, the mechanism of collateral artery development is difficult to validate. METHODS AND RESULTS: Collateral arteries were visualized using micro-x-ray computed tomography. Developmental characteristics were assessed using confocal microscopy. We conducted a single-center, retrospective, observational study and assessed the dilatation of collateral arteries on ischemic sides. We quantified the vascular volume in both ischemic and nonischemic legs. A prominent increase in vascular volume was observed in the ischemic leg using a murine hind-limb ischemia model. We also performed qualitative assessment and confirmed that the inferior gluteal artery functioned as a major collateral source. Serial analysis of murine hind-limb vessel development revealed that the inferior gluteal artery was a remnant of the ischial artery, which emerged as a representative vessel on the dorsal side during hind-limb organogenesis. We retrospectively analyzed consecutive patients who were admitted for the diagnosis or treatment of peripheral artery disease. The diameter of the inferior gluteal artery on the ischemic side showed significant dilatation compared with that on the nonischemic side. CONCLUSIONS: Our findings indicate that an embryonic remnant artery can become a collateral source under ischemic conditions. Flow enhancement in the inferior gluteal artery might become a novel therapeutic approach for patients with peripheral artery disease. PMID- 29572324 TI - Left Atrial Epicardial Fat Volume Is Associated With Atrial Fibrillation: A Prospective Cardiovascular Magnetic Resonance 3D Dixon Study. AB - BACKGROUND: Recent studies demonstrated a strong association between atrial fibrillation (AF) and epicardial fat around the left atrium (LA). We sought to assess whether epicardial fat volume around the LA is associated with AF, and to determine the additive value of LA-epicardial fat measurements to LA structural remodeling for identifying patients with AF using 3-dimensional multi-echo Dixon fat-water separated cardiovascular magnetic resonance. METHODS AND RESULTS: A total of 105 subjects were studied: 53 patients with a history of AF and 52 age matched patients with other cardiovascular diseases but no history of AF. The 3 dimensional multi-echo Dixon fat-water separated sequence was performed for LA epicardial fat measurements. AF patients had significantly greater LA-epicardial fat (28.9+/-12.3 and 14.2+/-7.3 mL for AF and non-AF, respectively; P<0.001) and LA volume (110.8+/-38.2 and 89.7+/-30.3 mL for AF and non-AF, respectively; P=0.002). LA-epicardial fat adjusted for LA volume was still higher in patients with AF compared with those without AF (P<0.001). LA-epicardial fat and hypertension were independently associated with the risk of AF (odds ratio, 1.17; 95% confidence interval, 1.10%-1.25%, P<0.001, and odds ratio, 3.29; 95% confidence interval, 1.17%-9.27%, P=0.03, respectively). In multivariable logistic regression analysis adjusted for body surface area, LA-epicardial fat remained significant and an increase per mL was associated with a 42% increase in the odds of AF presence (odds ratio, 1.42; 95% confidence interval, 1.23%-1.62%, P<0.001). Combined assessment of LA-epicardial fat and LA volume provided greater discriminatory performance for detecting AF than LA volume alone (c statistic=0.88 and 0.74, respectively, DeLong test; P<0.001). CONCLUSIONS: Cardiovascular magnetic resonance 3-dimensional Dixon-based LA-epicardial fat volume is significantly increased in AF patients. LA-epicardial fat measured by 3 dimensional Dixon provides greater performance for detecting AF beyond LA structural remodeling. PMID- 29572325 TI - Prevalence, Causes, and Predictors of 30-Day Readmissions Following Hospitalization With Acute Myocardial Infarction Complicated By Cardiogenic Shock: Findings From the 2013-2014 National Readmissions Database. AB - BACKGROUND: Prior studies have shown that survivors of acute myocardial infarction (AMI) complicated by cardiogenic shock are likely to have increased risk of readmissions in the early post-discharge period. However, the contemporary prevalence, reasons, and predictors of 30-day readmissions are not well known. METHODS AND RESULTS: Hospitalizations for a primary diagnosis of AMI complicated by cardiogenic shock, and discharged alive, were identified in the 2013 and 2014 Nationwide Readmissions Databases. Prevalence and reasons for 30 day unplanned readmissions were investigated. A hierarchical logistic regression model was used to identify independent predictors of 30-day readmissions. Among 1 116 933 patient hospitalizations with AMI, 39 807 (3.6%) had cardiogenic shock and were discharged alive. Their 30-day readmission rate was 18.6%, with a median time for readmission 10 days post discharge. Predictors of readmission included: non-ST-segment elevation myocardial infarction, female sex, low-income status, nonprivate insurance, chronic renal failure, long-term ventricular assist device or intra-aortic balloon placement, and tachyarrhythmia. The majority of readmissions were attributable to cardiac-related causes (52%); heart failure being the most frequent cardiac cause (39% of all cardiac causes). Noncardiac related readmissions included infections (14.9%), bleeding (5.3%), and respiratory causes (4.9%). The median cost per readmission was $9473 US dollars ($5037-20 199). CONCLUSIONS: Among survivors of AMI complicated by cardiogenic shock who were discharged from hospital, almost 1 in 5 are readmitted at 30 days, mainly because of cardiac reasons such as heart failure and new AMI. The risk of readmission was associated with certain baseline patient/hospital characteristics. PMID- 29572326 TI - Fuzzy and fast nuclear transport. AB - Exchange of macromolecules between the cytoplasm and the nucleus of all eukaryotic cells is controlled by nuclear pore complexes, which form a selective permeability barrier. The requirement for rapid but selective transport leads to a "transport paradox." A new experimental study now provides a thermodynamic explanation. PMID- 29572327 TI - A new actin-binding domain glues autophagy together. AB - Autophagy breaks down nonessential cellular components to replenish macromolecular building blocks during starvation. Nevertheless, the downstream events regulating vesicle trafficking during this essential cellular process are not yet fully defined. Xu et al. combined approaches of crystallography, biochemistry, and cell biology to show that the guanine nucleotide exchange factor DENND3 contains an actin-binding site they call "PHenn domain" in a region previously thought to be unstructured. PHenn domain binding to microfilaments is necessary for DENND3's participation in autophagy, providing a new link between autophagic stimulation and actin microfilaments. The findings by Xu et al. shed important new light on how membrane trafficking participates in critical steps of autophagy in relationship with actin microfilaments.

AB - Multidrug resistance protein, MRP1 (ABCC1) is a broad-spectrum ATP-binding cassette transporter that plays a major role in defense against dietary and environmental toxicants, in addition to contributing toward multidrug resistance of certain types of malignancy. Elucidating the molecular structure of hMRP1 is key to determining its mechanism of substrate recognition and transport. Here, we report the first successful attempt using cysteine-scanning mutagenesis coupled with cross-linking studies to probe the structure of hMRP1 in its native environment of the cell membrane or in membrane vesicles. We have established that an active 3Cys DeltaMRP1 (MRP204-1531) mutant, described in previous studies from our laboratory, is a suitable template with which to generate single- and double-cysteine mutants for performing cysteine mutagenesis studies. We have now used 3Cys DeltaMRP1 to probe the arrangement of several TM segments, as well as the location of individual amino acids in these regions. Cysteine residues were introduced into TMs 8, 14, 15, and 16 of 3Cys DeltaMRP1. The mutants were then subjected to chemical cross-linking analyses, and cross-linking was detected between the following cysteine pairs: Cys388 (TM7) and I1193C (TM16); Cys388 (TM7) and E1144C (TM15); R433C (TM8) and E1144C (TM15); and R433C (TM8) and T1082C (TM14). The aqueous accessibility of these residues and the possible implications of the differences between the open and closed states of the protein are also discussed. Moreover, using competition experiments involving a well characterized substrate and a cross-linking reagent for probing the Cys388/ I1193C mutant, we have defined these amino acid positions as a component of the potential site for estrone sulfate binding. PMID- 29572333 TI - Risk of Clinically Relevant Pharmacokinetic-Based Drug-Drug Interactions with Drugs Approved by the U.S. Food and Drug Administration Between 2013 and 2016. AB - A total of 103 drugs (including 14 combination drugs) were approved by the U.S. Food and Drug Administration from 2013 to 2016. Pharmacokinetic-based drug interaction profiles were analyzed using the University of Washington Drug Interaction Database, and the clinical relevance of these observations was characterized based on information from new drug application reviews. CYP3A was involved in approximately two-thirds of all drug-drug interactions (DDIs). Transporters (alone or with enzymes) participated in about half of all interactions, but most of these were weak-to-moderate interactions. When considered as victims, eight new molecular entities (NMEs; cobimetinib, ibrutinib, isavuconazole, ivabradine, naloxegol, paritaprevir, simeprevir, and venetoclax) were identified as sensitive substrates of CYP3A, two NMEs (pirfenidone and tasimelteon) were sensitive substrates of CYP1A2, one NME (dasabuvir) was a sensitive substrate of CYP2C8, one NME (eliglustat) was a sensitive substrate of CYP2D6, and one NME (grazoprevir) was a sensitive substrate of OATP1B1/3 (with changes in exposure greater than 5-fold when coadministered with a strong inhibitor). Approximately 75% of identified CYP3A substrates were also substrates of P-glycoprotein. As perpetrators, most clinical DDIs involved weak-to-moderate inhibition or induction. Only idelalisib showed strong inhibition of CYP3A, and lumacaftor behaved as a strong CYP3A inducer. Among drugs with large changes in exposure (>=5-fold), whether as victim or perpetrator, the most-represented therapeutic classes were antivirals and oncology drugs, suggesting a significant risk of clinical DDIs in these patient populations. PMID- 29572334 TI - Expert consensus regarding drivers of antimicrobial stewardship in companion animal veterinary practice: a Delphi study. AB - Antimicrobial resistance (AMR) is a global challenge facing both human and animal healthcare professionals; an effective response to this threat requires a 'One Health' approach to antimicrobial stewardship (AMS) to preserve important antibiotics for urgent clinical need. However, understanding of barriers and enablers to effective AMS behaviour in companion animal veterinary practice is currently limited. We conducted a Delphi study of 16 nationally recognised experts from UK-based veterinary policymakers, university academics and leaders of professional bodies. This Delphi study sought to identify veterinary behaviours which experts believe contribute to AMR and form vital aspects of AMS. Analysis of Delphi findings indicated a perceived hierarchy of behaviours, the most influential being antibiotic prescribing behaviours and interactions with clients. Other veterinary behaviours perceived as being important related to interactions with veterinary colleagues; infection control practices; and the use of diagnostic tests to confirm infection. Key barriers and enablers to AMS within each of these behavioural domains were identified. Specific interventions to address important barriers and enablers are recommended. To the authors' knowledge, this is the first study to establish expert consensus at a national level about which 'behaviours' (aspects of veterinarian practice) should be targeted in relation to AMR and AMS in companion animal veterinary practice. PMID- 29572335 TI - Effect of horse sex status on British Eventing competition performance: an observational study between 1998 and 2016. AB - To test the hypothesis that gender affects horse scores in eventing competition, data on the scores and points awarded to 681 horses was collected from the British Eventing website. Equal numbers of mares, geldings and stallions were used, all foaled during or after 1994 and aged 4-10 years. The study included five levels of competition (BE90, BE100, Novice, Intermediate and Advanced) and investigated differences in mean phased scores, total scores and rank in competition. Additionally, the mean and median 'BE points per competition' of each gender were compared. Significant differences in performance between genders were found at all levels except Advanced. Differences were highlighted in average phased and total scores, rank and median points per competition. There was an overall pattern of stallions and geldings outperforming mares, though this was not found to be true at all levels. The only area in which mares were found to perform significantly better than geldings or stallions was showjumping time penalties at BE90. PMID- 29572336 TI - GPR40-Mediated Galpha12 Activation by Allosteric Full Agonists Highly Efficacious at Potentiating Glucose-Stimulated Insulin Secretion in Human Islets. AB - GPR40 is a clinically validated molecular target for the treatment of diabetes. Many GPR40 agonists have been identified to date, with the partial agonist fasiglifam (TAK-875) reaching phase III clinical trials before its development was terminated due to off-target liver toxicity. Since then, attention has shifted toward the development of full agonists that exhibit superior efficacy in preclinical models. Full agonists bind to a distinct binding site, suggesting conformational plasticity and a potential for biased agonism. Indeed, it has been suggested that alternative pharmacology may be required for meaningful efficacy. In this study, we described the discovery and characterization of Compound A, a newly identified GPR40 allosteric full agonist highly efficacious in human islets at potentiating glucose-stimulated insulin secretion. We compared Compound A induced GPR40 activity to that induced by both fasiglifam and AM-1638, another allosteric full agonist previously reported to be highly efficacious in preclinical models, at a panel of G proteins. Compound A was a full agonist at both the Galphaq and Galphai2 pathways, and in contrast to fasiglifam Compound A also induced Galpha12 coupling. Compound A and AM-1638 displayed similar activity at all pathways tested. The Galpha12/Galpha13-mediated signaling pathway has been linked to protein kinase D activation as well as actin remodeling, well known to contribute to the release of insulin vesicles. Our data suggest that the pharmacology of GPR40 is complex and that Galpha12/Galpha13-mediated signaling, which may contribute to GPR40 agonists therapeutic efficacy, is a specific property of GPR40 allosteric full agonists.

AB - This document is designed to give guidance on assessing researchers in bioethics/medical ethics. It is intended to assist members of selection, confirmation and promotion committees, who are required to assess those conducting bioethics research when they are not from a similar disciplinary background. It does not attempt to give guidance on the quality of bioethics research, as this is a matter for peer assessment. Rather it aims to give an indication of the type, scope and amount of research that is the expected in this field. It does not cover the assessment of other activities such as teaching, policy work, clinical ethics consultation and so on, but these will be mentioned for additional context. Although it mentions the UK's Research Excellence Framework (REF), it is not intended to be a detailed analysis of the place of bioethics in the REF. PMID- 29572339 TI - Montgomery, informed consent and causation of harm: lessons from Australia or a uniquely English approach to patient autonomy? AB - The UK Supreme Court in Montgomery v Lanarkshire Health Board adopts an approach to information disclosure in connection with clinical treatment that moves away from medical paternalism towards a more patient-centred approach. In doing so, it reinforces the protection afforded to informed consent and autonomous patient decision making under the law of negligence. However, some commentators have expressed a concern that the widening of the healthcare providers' duty of disclosure may provide impetus, in future cases, for courts to adopt a more rigorous approach to the application of causation principles. The aim would be to limit liability but, in turn, it would also limit autonomy protection. Such a restrictive approach has recently been adopted in Australia as a result of the High Court decision in Wallace v Kam This paper considers whether such an approach is likely under English negligence law and discusses case law from both jurisdictions in order to provide a point of comparison from which to scope the post-Montgomery future.

AB - Because of their lower bleeding risk and simplicity of use, direct oral anticoagulants (DOACs) could represent an interesting alternative to conventional anticoagulant treatment with vitamin K antagonists for patients with pulmonary arterial hypertension (PAH). P-glycoprotein (P-gp) plays a key role in DOAC pharmacokinetics. Type 5-phosphodiesterase inhibitors (PDE5is), a drug class commonly used in the treatment of PAH, have been shown to strongly inhibit P-gp. This work aimed to assess potential P-gp-mediated drug-drug interactions between PDE5is and DOACs using in vitro methods. A cellular model of drug transport assay, using P-gp-overexpressing Madin-Darby canine kidney cells (transfected with the human P-gp gene), was used to determine the bidirectional permeabilities of two DOACs (rivaroxaban and apixaban) in the absence and presence of increasing concentrations (0.5-100 uM) of three PDE5is (sildenafil, tadalafil, and vardenafil). Permeabilities and efflux ratios were calculated from DOAC concentrations, were measured with liquid chromatography coupled with mass spectrometry, and were subsequently used to determine the PDE5i percentage of inhibition and half maximal inhibitory concentration (IC50 ). Rivaroxaban efflux was inhibited by 99%, 66%, and 100% with 100 uM sildenafil, tadalafil, and vardenafil, respectively. Similarly, apixaban efflux was inhibited by 97%, 74%, and 100%, respectively. The IC50 values of the three PDE5is were 8, 28, and 5 uM for rivaroxaban and 23, 15, and 3 uM for apixaban, respectively. This study showed strong in vitro inhibition of DOAC efflux by PDE5is. In vivo studies are required to determine the clinical relevance of these interactions.

AB - Docosahexaenoic acid (DHA) and its bioactive compounds may have suppressive effects on inflammation, endoplasmic reticulum (ER) stress, and insulin resistance. Protectin DX (PDX), a double lipoxygenase product from DHA has shown a suppressive effect on inflammation and insulin resistance. However, the effects of PDX on ER stress and hepatic steatosis have not been elucidated yet. Herein we report that PDX could stimulate the AMP-activated protein kinase (AMPK) phosphorylation, thereby upregulating oxygen-regulated protein 150 (ORP150) expression in a dose-dependent manner. Treatment of HepG2 cells with PDX attenuated the palmitate-induced triglyceride accumulation through regulation of the sterol regulatory element-binding protein 1 (SREBP1)-mediated pathway. To deal with the pharmacological significance in the protective effects of PDX on hepatic steatosis, we performed in vivo experiments. In a mouse model, the PDX administration would alleviate the high-fat diet-induced hepatic steatosis and trigger the hepatic AMPK phosphorylation and ORP150 expression. PDX improved palmitate-induced and HFD-induced impairment of hepatic lipid metabolism and steatosis through suppression of ER stress via an AMPK-ORP150-dependent pathway. PMID- 29572343 TI - Nature-based supportive care opportunities: a conceptual framework. AB - OBJECTIVE: Given preliminary evidence for positive health outcomes related to contact with nature for cancer populations, research is warranted to ascertain possible strategies for incorporating nature-based care opportunities into oncology contexts as additional strategies for addressing multidimensional aspects of cancer patients' health and recovery needs. The objective of this study was to consolidate existing research related to nature-based supportive care opportunities and generate a conceptual framework for discerning relevant applications in the supportive care setting. METHODS: Drawing on research investigating nature-based engagement in oncology contexts, a two-step analytic process was used to construct a conceptual framework for guiding nature-based supportive care design and future research. Concept analysis methodology generated new representations of understanding by extracting and synthesising salient concepts. Newly formulated concepts were transposed to findings from related research about patient-reported and healthcare expert-developed recommendations for nature-based supportive care in oncology. RESULTS: Five theoretical concepts (themes) were formulated describing patients' reasons for engaging with nature and the underlying needs these interactions address. These included: connecting with what is genuinely valued, distancing from the cancer experience, meaning-making and reframing the cancer experience, finding comfort and safety, and vital nurturance. Eight shared patient and expert recommendations were compiled, which address the identified needs through nature-based initiatives. Eleven additional patient-reported recommendations attend to beneficial and adverse experiential qualities of patients' nature-based engagement and complete the framework. CONCLUSIONS: The framework outlines salient findings about helpful nature-based supportive care opportunities for ready access by healthcare practitioners, designers, researchers and patients themselves. PMID- 29572344 TI - Advance care planning: the impact of Ceiling of Treatment plans in patients with Coordinate My Care. AB - OBJECTIVES: The aim of this evaluation is to describe the components and results of urgent care planning in Coordinate My Care (CMC), a digital clinical service for patients with life-limiting illness, for use if a patient is unable to make or express choices. Ceiling of treatment (CoT) plans were created detailing where the patient would like to receive their care and how aggressive medical interventions should be. METHODS: A retrospective service evaluation was completed of all CMC records created between December 2015 and September 2016 (n=6854). CMC records were divided into two cohorts: those with a CoT plan and those without. The factors associated with these cohorts were reviewed including age, diagnosis, resuscitation status and preferences for place of death (PPD). Analysis of the non-mandatory free text section was carried out. RESULTS: Two thirds of patients had recorded decisions about CoT. Regardless of which CoT option was chosen, for most patients, PPD was home or care home. Patients with a CoT plan were more likely to have a documented resuscitation status.Patients with a CoT were more likely to die in their PPD (82%vs71%, OR 1.79, p<0.0001). A higher proportion of patients with a CoT decision died outside hospital. CONCLUSION: This analysis demonstrates that a substantial proportion of patients are willing to engage in urgent care planning. Three facets of urgent care planning identified include PPD, CoT and resuscitation status. PMID- 29572345 TI - Does being overweight contribute to longer survival rates in myelodysplastic syndrome?

PMID- 29572348 TI - Novel Anti-Inflammatory Peptides Based on Chemokine-Glycosaminoglycan Interactions Reduce Leukocyte Migration and Disease Severity in a Model of Rheumatoid Arthritis. AB - Inflammation is characterized by the infiltration of leukocytes from the circulation and into the inflamed area. Leukocytes are guided throughout this process by chemokines. These are basic proteins that interact with leukocytes to initiate their activation and extravasation via chemokine receptors. This is enabled through chemokine immobilization by glycosaminoglycans (GAGs) at the luminal endothelial surface of blood vessels. A specific stretch of basic amino acids on the chemokine, often at the C terminus, interacts with the negatively charged GAGs, which is considered an essential interaction for the chemokine function. Short-chain peptides based on this GAG-binding region of the chemokines CCL5, CXCL8, and CXCL12gamma were synthesized using standard Fmoc chemistry. These peptides were found to bind to GAGs with high affinity, which translated into a reduction of leukocyte migration across a cultured human endothelial monolayer in response to chemokines. The leukocyte migration was inhibited upon removal of heparan sulfate from the endothelial surface and was found to reduce the ability of the chemokine and peptide to bind to endothelial cells in binding assays and to human rheumatoid arthritis tissue. The data suggest that the peptide competes with the wild-type chemokine for binding to GAGs such as HS and thereby reduces chemokine presentation and subsequent leukocyte migration. Furthermore, the lead peptide based on CXCL8 could reduce the disease severity and serum levels of the proinflammatory cytokine TNF-alpha in a murine Ag-induced arthritis model. Taken together, evidence is provided for interfering with the chemokine-GAG interaction as a relevant therapeutic approach. PMID- 29572349 TI - Astrocytic glycogen metabolism in the healthy and diseased brain. AB - The brain contains a fairly low amount of glycogen, mostly located in astrocytes, a fact that has prompted the suggestion that glycogen does not have a significant physiological role in the brain. However, glycogen metabolism in astrocytes is essential for several key physiological processes and is adversely affected in disease. For instance, diminished ability to break down glycogen impinges on learning, and epilepsy, Alzheimer's disease, and type 2 diabetes are all associated with abnormal astrocyte glycogen metabolism. Glycogen metabolism supports astrocytic K+ and neurotransmitter glutamate uptake and subsequent glutamine synthesis-three fundamental steps in excitatory signaling at most brain synapses. Thus, there is abundant evidence for a key role of glycogen in brain function. Here, we summarize the physiological brain functions that depend on glycogen, discuss glycogen metabolism in disease, and investigate how glycogen breakdown is regulated at the cellular and molecular levels. PMID- 29572350 TI - Gain-of-function mutations in granulocyte colony-stimulating factor receptor (CSF3R) reveal distinct mechanisms of CSF3R activation. AB - Granulocyte colony-stimulating factor (G-CSF or CSF3) and its receptor CSF3R regulate granulopoiesis, neutrophil function, and hematopoietic stem cell mobilization. Recent studies have uncovered an oncogenic role of mutations in the CSF3R gene in many hematologic malignancies. To find additional CSF3R mutations that give rise to cell transformation, we performed a cellular transformation assay in which murine interleukin 3 (IL-3)-dependent Ba/F3 cells were transduced with WT CSF3R plasmid and screened for spontaneous growth in the absence of IL-3. Any outgrowth clones were sequenced to identify CSF3R mutations with transformation capacity. We identified several novel mutations and determined that they transform cells via four distinct mechanisms: 1) cysteine- and disulfide bond-mediated dimerization (S581C); 2) polar, noncharged amino acid substitution at the transmembrane helix dimer interface at residue Thr-640; 3) increased internalization by a Glu-524 substitution that mimics a low G-CSF dose; and 4) hydrophobic amino acid substitutions in the membrane-proximal residues Thr 612, Thr-615, and Thr-618. Furthermore, the change in signaling activation was related to an altered CSF3R localization. We also found that CSF3R-induced STAT3 and ERK activations require CSF3R internalization, whereas STAT5 activation occurred at the cell surface. Cumulatively, we have expanded the regions of the CSF3R extracellular and transmembrane domains in which missense mutations exhibit leukemogenic capacity and have further elucidated the mechanistic underpinnings that underlie altered CSF3R expression, dimerization, and signaling activation.

AB - Atherosclerosis is a chronic inflammatory disease characterized by the entrapment of apolipoprotein B-containing lipoproteins in the arterial intima, leading to local inflammation. T helper (Th) cell 1-mediated immune responses have been associated with atherosclerosis, and the cytokine interleukin-25 (IL-25 or IL 17E) has been reported to potentially regulate Th1 cell- and Th17 cell-related immune responses. In this study, we evaluated the effects of complete IL-25 deficiency or of a temporal IL-25 blockade on atherosclerosis development in apolipoprotein E-deficient (Apoe-/-) mice. Mice deficient in both apolipoprotein E and IL-25 (Apoe-/-/IL-25-/-) had more Th1 cells in the spleen, along with elevated plasma levels of IL-17 and an increased release of splenic interferon gamma (INF-gamma). In support of this observation, a 4-week-long treatment of young Apoe-/- mice (at 10-14 weeks of age) with an IL-25-blocking antibody increased the release of Th1/Th17-associated cytokines in the spleen. In both mouse models, these findings were associated with increased atherosclerotic plaque formation in the aortic arch. We conclude that complete IL-25 deficiency and a temporal IL-25 blockade during early plaque development aggravate atherosclerosis development in the aortic arch of Apoe-/- mice, accompanied by an increase in Th1/Th17-mediated immune responses. Our finding that endogenous IL-25 has an atheroprotective role in the murine aortic arch has potential implications for atherosclerosis development and management in humans. PMID- 29572353 TI - Remember the retina: retinal disorders presenting to neurologists. AB - General neurologists and stroke specialists are regularly referred cases of visual disturbance by general practitioners, emergency doctors and even ophthalmologists. Particularly when the referral comes from ophthalmologists, our assessment tends to focus on the optic nerve; however, retinal conditions may mimic optic neuropathy and are easily missed. Their diagnosis requires specific investigations that are rarely available in a neurology clinic. This article focuses on how a general neurologist can identify retinal problems from the clinical assessment and how to proceed with initial investigations. The following cases were all referred to a consultant neurologist (GTP) from ophthalmology services as optic neuropathies or other neurological disorders. Part A of the summary describes the presentation and findings in the neurology clinic; part B describes the subsequent specialist assessment in the neuro-ophthalmology/eye clinic.

AB - BACKGROUND: In population studies, vaping is often treated as a dichotomous exposure (present/absent) without consideration of specific vaping devices and materials being used. A survey instrument is needed to record specific vaping devices and materials. METHODS: We developed a database of 613 vaping device models and 3196 vaping liquid products, indexed by device brand, device type, liquid brand, liquid name and liquid flavour type. We developed a survey instrument to allow participants to report their vaping device and liquid from the indexed lists. The survey was pilot tested with a convenience sample of 208 adults (>=age 21). We validated the vaping device and liquid responses with a recontact survey. We report the proportion of respondents finding their products, characteristics of people finding their products and survey response times. RESULTS: Devices used most frequently in the past 30 days were electronic cigarettes (33% of respondents), vaping pens (28%) and vaping mods (16%). Fifty seven per cent used liquids containing nicotine most frequently in the past 30 days, followed by liquids without nicotine (20%) and marijuana or hashish (10%). Most (85%) participants found their vaping device successfully (median 19.7 s) and 74% found their vaping liquid (median 19.8 s). Females and older adults were less likely to find their devices and liquids. Responses were validated for 91% and 76% of devices and e-liquids, respectively. CONCLUSIONS: This study demonstrated the feasibility of an internet-based survey instrument to record specific vaping factors for use in studies of vaping and health.

AB - The identification of transcription factor (TF) binding sites in the genome is critical to understanding gene regulatory networks (GRNs). While ChIP-seq is commonly used to identify TF targets, it requires specific ChIP-grade antibodies and high cell numbers, often limiting its applicability. DNA adenine methyltransferase identification (DamID), developed and widely used in Drosophila, is a distinct technology to investigate protein-DNA interactions. Unlike ChIP-seq, it does not require antibodies, precipitation steps, or chemical protein-DNA crosslinking, but to date it has been seldom used in mammalian cells due to technical limitations. Here we describe an optimized DamID method coupled with next-generation sequencing (DamID-seq) in mouse cells and demonstrate the identification of the binding sites of two TFs, POU5F1 (also known as OCT4) and SOX2, in as few as 1000 embryonic stem cells (ESCs) and neural stem cells (NSCs), respectively. Furthermore, we have applied this technique in vivo for the first time in mammals. POU5F1 DamID-seq in the gastrulating mouse embryo at 7.5 d post coitum (dpc) successfully identified multiple POU5F1 binding sites proximal to genes involved in embryo development, neural tube formation, and mesoderm-cardiac tissue development, consistent with the pivotal role of this TF in post implantation embryo. This technology paves the way to unprecedented investigation of TF-DNA interactions and GRNs in specific cell types of limited availability in mammals, including in vivo samples. PMID- 29572361 TI - Systemic inflammation and suicide risk: cohort study of 419 527 Korean men and women. AB - BACKGROUND: Data from only one study have been used to examine the relationship between systemic inflammation and later suicide risk, and a strong positive association was apparent. More research is needed, particularly looking at gender, not least because women are seemingly more vulnerable to inflammation induced mood changes than men. METHODS: The Korean Cancer Prevention Study had a cohort of over 1 million individuals aged 30-95 years at baseline examination between 1992 and 1995, when white blood cell count, our marker of systemic inflammation, was assessed. RESULTS: A mean of 16.6 years of mortality surveillance gave rise to 1010 deaths from suicide in 106 643 men, and 1019 deaths from suicide in 312 884 women. There was little evidence of an association between our inflammation marker and suicide mortality in men after multiple adjustments. In women, however, those in the second inflammation quartile and higher experienced around 30% increase risk of death (HR 1.35; 95% CI: 1.11 1.64). CONCLUSIONS: Higher levels of systemic inflammation were moderately related to an elevated risk of suicide death in women but not in men.

AB - Clinical differentiation of atypical breast abscesses from necrotic tumour in premenopausal women is challenging and may delay appropriate therapy. In this case report, we present a 36-year-old woman with signs, symptoms and conventional imaging features of malignancy who underwent breast MRI. On diffusion-weighted imaging (DWI), profoundly low apparent diffusion coefficient values were a distinguishing sign of breast abscess from necrotic breast cancer, and helped manage the patient conservatively. We present a companion case of necrotic breast tumour highlighting significant differences in DWI. PMID- 29572360 TI - Altered compensatory cytokine signaling underlies the discrepancy between Flt3-/- and Flt3l-/- mice. AB - The receptor Flt3 and its ligand Flt3L are both critical for dendritic cell (DC) development, but DC deficiency is more severe in Flt3l-/- mice than in Flt3-/- mice. This has led to speculation that Flt3L binds to another receptor that also supports DC development. However, we found that Flt3L administration does not generate DCs in Flt3-/- mice, arguing against a second receptor. Instead, Flt3-/- DC progenitors matured in response to macrophage colony-stimulating factor (M CSF) or stem cell factor, and deletion of Csf1r in Flt3-/- mice further reduced DC development, indicating that these cytokines could compensate for Flt3. Surprisingly, Flt3-/- DC progenitors displayed enhanced M-CSF signaling, suggesting that loss of Flt3 increased responsiveness to other cytokines. In agreement, deletion of Flt3 in Flt3l-/- mice paradoxically rescued their severe DC deficiency. Thus, multiple cytokines can support DC development, and the discrepancy between Flt3-/- and Flt3l-/- mice results from the increased sensitivity of Flt3-/- progenitors to these cytokines.

EDS is a rare and heterogeneous condition affecting collagen synthesis and presents multiple difficulties in a surgical setting. Management of this case of testicular torsion was complicated by impaired cognition of the patient, difficulty with intubation, a contralateral undescended testis and postoperative bleeding. We discuss the specific challenges faced in this case of testicular torsion with longstanding ischaemia and perioperative considerations of EDS. PMID- 29572365 TI - A rare presentation of haematuria: hip prosthesis in the bladder. AB - An 80-year-old woman presented to our department with visible haematuria and stage II acute kidney injury (AKI). She had stage IIB cervical cancer, for which she received chemotherapy and external beam radiotherapy in 2003. Four years later, she had a left dynamic hip screw for an extracapsular neck of femur fracture following a fall. In 2010, she underwent a right total hip replacement owing to osteoarthritis, and it was subsequently revised in 2012 owing to a right acetabular component failure. In this admission, her AKI improved with intravenous fluid administration and her haematuria settled following catheterisation with a three-way catheter and bladder irrigation with saline. She underwent a flexible cystoscopy which revealed that a part of her right hip prosthesis was in the bladder, having eroded through the right bony pelvis. However, she declined any surgical interventions. PMID- 29572366 TI - Importance of source images of time-of-flight magnetic resonance angiography in the diagnosis of low-flow dural arteriovenous fistulae after traumatic brain injury. AB - Three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) can reliably detect dural arteriovenous fistula (dAVF); however, TOF source images should be checked in cases with low-flow dAVFs. A 69-year-old woman reported intractable pulsatile tinnitus after head trauma. It was difficult to diagnose dAVF using conventional MRA, but it was confirmed using a TOF source image. Cerebral angiography revealed a dAVF with a small shunted pouch draining into the sigmoid sinus, accompanying the arterial jet flow. Transarterial embolisation of the shunted pouch completely obliterated the dAVF. The patient's tinnitus immediately disappeared after embolisation. This case suggests that a low-flow Borden type I dAVF is undetectable using conventional MRA, and we emphasise the importance of evaluating TOF source images. Transarterial embolisation of the shunted pouch while preserving the normal sinus flow was safe and effective. PMID- 29572367 TI - Myocarditis secondary to smallpox vaccination. AB - The development of vaccines ushered in the most profound advancement in 20th century medicine, and have widely been regarded as the one of the most important scientific discovery in the history of mankind. However, vaccines are not without risk; reactions can range from injection site reactions to life-threatening anaphylaxis. Among the more serious vaccine-related sequela is myocarditis. Although myocarditis has been reported following many different vaccines, the smallpox vaccine has the strongest association. We report a case of a 36-year-old active duty service member presenting with progressive dyspnoea, substernal chest pain and lower extremity swelling 5 weeks after receiving the vaccinia vaccination. The aetiology of his acute decompensated heart failure was determined to be from myocarditis. Although the majority of cases of myocarditis resolve completely, some patients develop chronic heart failure and even death. Vaccine-associated myocarditis should always be on the differential for patients that exhibit cardiopulmonary symptoms after recent vaccinations. PMID- 29572368 TI - Complication of intraprosthetic dislocation of dual-mobility hip implant following closed reduction. AB - Total hip replacement is a successful operation for the management of hip pain but there are potential complications, of which dislocation is one of the most common. The management of recurrent dislocation is a challenging problem that requires a multimodal approach and the use of dual-mobility implants is one option. We present a patient who was previously revised with a dual-mobility implant for recurrent dislocation, who had a complication after closed reduction of a subsequent intraprosthetic dislocation. Following a missed radiographical diagnosis, the patient experienced mechanical symptoms on hip flexion caused by a disassociated dual-mobility implant. Subsequent surgical removal of the failed implant and revision was required. Careful study of radiographs revealed an eccentric femoral head and evidence of the disassociated implant within the surrounding soft tissues. Radiographs following closed reduction of intraprosthetic dislocations should be scrutinised closely to detect implant failure to prevent further complications.

AB - In this paper, we present two women with hypokalaemic rhabdomyolysis in the context of increased diuretic intake and gastroenteritis, respectively. While their clinical manifestations and laboratory results were strikingly similar, two different underlying disorders were subsequently unveiled. The first patient was diagnosed with Conn syndrome, and adrenalectomy led to significant improvement of hypertension and sustained normokalaemia. The diagnosis in the second patient was Gitelman syndrome. Electrolyte supplements improved long-term lassitude and the frequency of muscle cramps declined significantly. These case vignettes illustrate the importance of establishing the underlying cause of hypokalaemia.

AB - An 8-year-old child underwent uneventful levator plication surgery for unilateral congenital ptosis. Postoperative course for initial few days was uneventful but on day 7, the patient was brought with conjunctival prolapse from the undersurface of upper eyelid due to tarsal kinking and eversion. Early medical management was initiated with frequent surface lubrication to avoid conjunctiva dryness. Under general anaesthesia, right-sided conjunctival repositioning was performed with an eyelid spatula supplemented by three forniceal stay sutures to retain the conjunctiva in its anatomical place. To reverse the tarsal kinking, continued downward traction suture was placed for a period of 2 weeks. At the end of 4 weeks, the conjunctival prolapse was completely resolved with a well-formed superior fornix. At the end of 3 months, the symmetric eyelid position was maintained without any additional complications. PMID- 29572372 TI - Parkinson's disease with hypocalcaemia: adult presentation of 22q11.2 deletion syndrome. AB - A growing amount of evidence indicates that 22q11.2 deletion syndrome (22q11.2DS) increases the risk of early-onset Parkinson's disease (EOPD). Here, we describe a 36-year-old patient with EOPD. The patient presented with 22q11.2DS features, including associated cognitive disabilities, hypocalcaemia and facial dysmorphia that led us to screen for and confirm this deletion. In addition, hypocalcaemia and vitamin D deficiency were the main factors responsible for severe, painful muscle spasms that were non-levodopa (L-Dopa) responsive and remitted after calcium and vitamin D replacement therapy. Many patients with this deletion remain undiagnosed until adulthood due to the absence of 'major' phenotypic hallmarks, which usually present during early childhood. Later onset problems involving various medical subspecialties are increasingly recognised as important components of 22q11.2DS. Therefore, the multisystem nature and associated burden of morbidities demand a high degree of suspicion for this entity from all clinicians regardless of their medical subspecialty.

AB - Endobronchial foreign bodies (EFBs) are present in various settings, such as eating or dental procedure. Accidental aspiration of foreign bodies is more common in children; however, cases of adult foreign body aspiration exist. Traumatic incidents can precipitate endobronchial aspiration of foreign bodies. Loss of consciousness, such as in coma, can result in foreign bodies being easily inhaled into the airways. Teeth or vehicle parts have been reported as EFBs following traumatic incidents. We report on a patient with chronic, sustained cough following maxillofacial trauma. Chest CT revealed an abnormal calcified endobronchial opacity. Flexible bronchoscopy confirmed the presence of an endobronchial foreign body in the left main bronchus. Following removal by bronchial forceps, the body was identified as a human bone fragment. Successful removal of the endobronchial bone fragment resulted in complete symptom remission. We concluded that post-traumatic respiratory complaints should be comprehensively evaluated, even if mild.

PARTICIPANTS: 109 107 men and women aged 45-90 years. MAIN OUTCOME MEASURE: Physical functioning assessed using the walking speed test, a valid index of overall functional capacity. Years of functioning lost was computed as a metric to quantify the difference in walking speed between those exposed and unexposed to low socioeconomic status and risk factors. RESULTS: According to mixed model estimations, men aged 60 and of low socioeconomic status had the same walking speed as men aged 66.6 of high socioeconomic status (years of functioning lost 6.6 years, 95% confidence interval 5.0 to 9.4). The years of functioning lost for women were 4.6 (3.6 to 6.2). In men and women, respectively, 5.7 (4.4 to 8.1) and 5.4 (4.3 to 7.3) years of functioning were lost by age 60 due to insufficient physical activity, 5.1 (3.9 to 7.0) and 7.5 (6.1 to 9.5) due to obesity, 2.3 (1.6 to 3.4) and 3.0 (2.3 to 4.0) due to hypertension, 5.6 (4.2 to 8.0) and 6.3 (4.9 to 8.4) due to diabetes, and 3.0 (2.2 to 4.3) and 0.7 (0.1 to 1.5) due to tobacco use. In analyses restricted to high income countries, the number of years of functioning lost attributable to low socioeconomic status by age 60 was 8.0 (5.7 to 13.1) for men and 5.4 (4.0 to 8.0) for women, whereas in low and middle income countries it was 2.6 (0.2 to 6.8) for men and 2.7 (1.0 to 5.5) for women. Within high income countries, the number of years of functioning lost attributable to low socioeconomic status by age 60 was greater in the United States than in Europe. Physical functioning continued to decline as a function of unfavourable risk factors between ages 60 and 85. Years of functioning lost were greater than years of life lost due to low socioeconomic status and non-communicable disease risk factors. CONCLUSIONS: The independent association between socioeconomic status and physical functioning in old age is comparable in strength and consistency with those for established non-communicable disease risk factors. The results of this study suggest that tackling all these risk factors might substantially increase life years spent in good physical functioning. PMID- 29572377 TI - Preclinical evaluation of NUDT15-guided thiopurine therapy and its effects on toxicity and antileukemic efficacy. AB - Thiopurines (eg, 6-mercaptopurine [MP]) are highly efficacious antileukemic agents, but they are also associated with dose-limiting toxicities. Recent studies by us and others have identified inherited NUDT15 deficiency as a novel genetic cause of thiopurine toxicity, and there is a strong rationale for NUDT15 guided dose individualization to preemptively mitigate adverse effects of these drugs. Using CRISPR-Cas9 genome editing, we established a Nudt15-/- mouse model to evaluate the effectiveness of this strategy in vivo. Across MP dosages, Nudt15 /- mice experienced severe leukopenia, rapid weight loss, earlier death resulting from toxicity, and more bone marrow hypocellularity compared with wild-type mice. Nudt15-/- mice also showed excessive accumulation of a thiopurine active metabolite (ie, DNA-incorporated thioguanine nucleotides [DNA-TG]) in an MP dose dependent fashion, as a plausible cause of increased toxicity. MP dose reduction effectively normalized systemic exposure to DNA-TG in Nudt15-/- mice and largely eliminated Nudt15 deficiency-mediated toxicity. In 95 children with acute lymphoblastic leukemia, MP dose adjustment also directly led to alteration in DNA TG levels, the effects of which were proportional to the degree of NUDT15 deficiency. Using leukemia-bearing mice with concordant Nudt15 genotype in leukemia and host, we also confirmed that therapeutic efficacy was preserved in Nudt15-/- mice receiving a reduced MP dose compared with Nudt15+/+ counterparts exposed to a standard dose. In conclusion, we demonstrated that NUDT15 genotype guided MP dose individualization can preemptively mitigate toxicity without compromising therapeutic efficacy. PMID- 29572379 TI - Stable lines and clones of long-term proliferating normal, genetically unmodified murine common lymphoid progenitors. AB - Common lymphoid progenitors (CLPs) differentiate to T and B lymphocytes, dendritic cells, natural killer cells, and innate lymphoid cells. Here, we describe culture conditions that, for the first time, allow the establishment of lymphoid-restricted, but uncommitted, long-term proliferating CLP cell lines and clones from a small pool of these cells from normal mouse bone marrow, without any genetic manipulation. Cells from more than half of the cultured CLP clones could be induced to differentiate to T, B, natural killer, dendritic, and myeloid cells in vitro. Cultured, transplanted CLPs transiently populate the host and differentiate to all lymphoid subsets, and to myeloid cells in vivo. This simple method to obtain robust numbers of cultured noncommitted CLPs will allow studies of cell-intrinsic and environmentally controlled lymphoid differentiation programs. If this method can be applied to human CLPs, it will provide new opportunities for cell therapy of patients in need of myeloid-lymphoid reconstitution. PMID- 29572378 TI - Mechanisms of resistance to EZH2 inhibitors in diffuse large B-cell lymphomas. AB - Resistance to targeted therapies has become increasingly prevalent. We noted that resistance to different targeted therapies occurs by largely common mechanisms. In this study, we used this information for identifying the mechanisms of resistance to enhancer of zeste homolog 2 (EZH2) inhibitors in diffuse large B cell lymphoma (DLBCL) harboring EZH2 mutations. We discovered that EZH2 inhibitor resistant DLBCL cells showed activation of the insulin-like growth factor 1 receptor (IGF-1R), MEK, and phosphoinositide-3-kinase (PI3K) pathways. Constitutive activation of IGF-1R, MEK, or PI3K pathways was sufficient to confer resistance to EZH2 inhibitors in DLBCL. The activation of the PI3K/AKT and MAPK pathways decreased TNFSF10 and BAD expression through a FOXO3-dependent mechanism, which was required for the antitumor effects of EZH2i GSK126. We also identified multiple acquired mutations in EZH2 inhibitor-resistant DLBCL cell lines. These mutations independently conferred resistance to EZH2 inhibitors. Mechanistically, cellular thermal shift assays revealed that the acquired EZH2 mutations that confer resistance to EZH2 inhibitors prevent EZH2 inhibitor binding to the EZH2 mutants. Notably, EZH2 inhibitor GSK126- and EPZ-6438 resistant DLBCL cells remained sensitive to the EZH2 inhibitor UNC1999 and embryonic ectoderm development protein inhibitor EED226, which provides an opportunity to treat DLBCLs that are resistant to these drugs. Collectively, our results underpin the importance for developing a unified approach for forestalling drug resistance by prospectively considering lessons learned from the use of different targeted therapeutic agents. PMID- 29572380 TI - The identification of fibrosis-driving myofibroblast precursors reveals new therapeutic avenues in myelofibrosis. AB - Myofibroblasts are fibrosis-driving cells and are well characterized in solid organ fibrosis, but their role and cellular origin in bone marrow fibrosis remains obscure. Recent work has demonstrated that Gli1+ and LepR+ mesenchymal stromal cells (MSCs) are progenitors of fibrosis-causing myofibroblasts in the bone marrow. Genetic ablation of Gli1+ MSCs or pharmacologic targeting of hedgehog (Hh)-Gli signaling ameliorated fibrosis in mouse models of myelofibrosis (MF). Moreover, pharmacologic or genetic intervention in platelet-derived growth factor receptor alpha (Pdgfralpha) signaling in Lepr+ stromal cells suppressed their expansion and ameliorated MF. Improved understanding of cellular and molecular mechanisms in the hematopoietic stem cell niche that govern the transition of MSCs to myofibroblasts and myofibroblast expansion in MF has led to new paradigms in the pathogenesis and treatment of MF. Here, we highlight the central role of malignant hematopoietic clone-derived megakaryocytes in reprogramming the hematopoietic stem cell niche in MF with potential detrimental consequences for hematopoietic reconstitution after allogenic stem cell transplantation, so far the only therapeutic approach in MF considered to be curative. We and others have reported that targeting Hh-Gli signaling is a therapeutic strategy in solid organ fibrosis. Data indicate that targeting Gli proteins directly inhibits Gli1+ cell proliferation and myofibroblast differentiation, which results in reduced fibrosis severity and improved organ function. Although canonical Hh inhibition (eg, smoothened [Smo] inhibition) failed to improve pulmonary fibrosis, kidney fibrosis, or MF, the direct inhibition of Gli proteins ameliorated fibrosis. Therefore, targeting Gli proteins directly might be an interesting and novel therapeutic approach in MF.

PMID- 29572383 TI - CTRP3 attenuates high-fat diet-induced male reproductive dysfunction in mice. AB - Recent studies have suggested a role for abdominal obesity in male infertility. Previous studies have found that cell apoptosis exerts an important role in obesity-related male infertility. C1q/TNF-related protein 3 (CTRP3), a paralog of adiponectin, has been proposed to exert anti-apoptotic effects and to attenuate diabetes-related cardiac injuries. However, the role of CTRP3 in high-fat diet (HFD)-induced spermatogenic impairment remains unclear. In the present study, we fed male mice an HFD for 24 weeks to induce obesity. The expression of CTRP3 was decreased by HFD feeding. Supplementation with the recombinant human globular domain of CTRP3 (0.25 MUg/g/day) for 4 weeks beginning at 20 weeks of the HFD improved spermatogenic function in the HFD-fed mice, which were characterized by improved testis morphology, increased testis weight/body weight ratio, and increased sperm count, sperm viability, and sperm motility. We also found that CTRP3 infusion resulted in the attenuation of endoplasmic reticulum (ER) stress and the activation of silence information regulator 1 (SIRT1) in the testes of obese mice. Our in vitro study also suggested that CTRP3 attenuated the palmitic acid (PA)-induced reductions in sperm viability and motility via the inhibition of ER stress. Moreover, germ cell-specific Sirtuin1 knockout abolished the protective effects of CTRP3 in vivo and in vitro. In vitro studies of human sperm showed that the protective effects of CTRP3 on sperm viability and motility were abrogated by a specific inhibitor of SIRT1. Thus, our results demonstrated that CTRP3 expression protected against HFD-induced spermatogenic deficiency through the SIRT1/ER stress pathway. PMID- 29572382 TI - Correlative live and super-resolution imaging reveals the dynamic structure of replication domains. AB - Chromosome organization in higher eukaryotes controls gene expression, DNA replication, and DNA repair. Genome mapping has revealed the functional units of chromatin at the submegabase scale as self-interacting regions called topologically associating domains (TADs) and showed they correspond to replication domains (RDs). A quantitative structural and dynamic description of RD behavior in the nucleus is, however, missing because visualization of dynamic subdiffraction-sized RDs remains challenging. Using fluorescence labeling of RDs combined with correlative live and super-resolution microscopy in situ, we determined biophysical parameters to characterize the internal organization, spacing, and mechanical coupling of RDs. We found that RDs are typically 150 nm in size and contain four co-replicating regions spaced 60 nm apart. Spatially neighboring RDs are spaced 300 nm apart and connected by highly flexible linker regions that couple their motion only <550 nm. Our pipeline allows a robust quantitative characterization of chromosome structure in situ and provides important biophysical parameters to understand general principles of chromatin organization. PMID- 29572384 TI - Cardiotrophin-1 attenuates experimental colitis in mice. AB - Cardiotrophin-1 (CT-1) holds potent anti-inflammatory, cytoprotective, and anti apoptotic effects in the liver, kidneys, and heart. In the present study, the role of endogenous CT-1 and the effect of exogenous CT-1 were evaluated in experimental ulcerative colitis. Colitis was induced in CT-1 knockout and wild type (WT) mice by administration of dextran sulphate sodium (DSS) in the drinking water during 7 days. CT-1 knockout mice showed higher colon damage and disease severity than WT mice. In addition, CT-1 (200 ug/kg/day, iv) or vehicle (as control) was administered during 3 days to WT, colitic mice, starting on day 4 after initiation of DSS. Disease activity index (DAI), inflammatory markers (tumor necrosis factor alpha (TNF-alpha), INFgamma, IL-17, IL-10, inducible nitric oxide synthase (iNOS)), colon damage, apoptosis (cleaved caspase 3), nuclear factor kappaB (NFkappaB) and STAT-3 activation, and bacterial translocation were measured. Compared with mice treated with DSS, mice also treated with exogenous CT-1 showed lower colon damage, DAI, plasma levels of TNFalpha, colon expression of TNF-alpha, INFgamma, IL-17, iNOS and cleaved caspase 3, higher NFkappaB and signal transducer and activator of transcription 3 (STAT3) pathways activation, and absence of bacterial translocation. We conclude that endogenous CT-1 plays a role in the defense and repair response of the colon against ulcerative lesions through an anti-inflammatory and anti-apoptotic effect. Supplementation with exogenous CT-1 ameliorates disease symptoms, which opens a potentially new therapeutic strategy for ulcerative colitis. PMID- 29572385 TI - MiR-27-3p regulates TLR2/4-dependent mouse alveolar macrophage activation by targetting PPARgamma. AB - Activation of alveolar macrophages (AMs) and the release of cytokines play critical roles in the pathogenesis of chronic obstructive pulmonary disease (COPD). However, little is known about the mechanisms of AM activation. miRNAs have recently emerged as key regulators of inflammation and as mediators of macrophage activation and polarization. We identified potential miRNAs related to AM activation using miRNA microarray analysis, which showed that miR-27-3p expression was up-regulated in AMs and the lung tissues of mice exposed to cigarette smoke (CS)/lipopolysaccharide (LPS), and found that miR-27-3p regulated proinflammatory cytokine production and AM polarization depending on TLR2/4 intracellular signaling in AMs. We also found that miR-27-3p controlled TLR2/4 signaling in AMs via targetting the 3'-UTR sequences of peroxisome proliferator activated receptor gamma (PPARgamma) and inhibiting PPARgamma activation. Moreover, we found that PPARgamma activation not only inhibited CS/LPS-induced TLR2/4 expression and miR-27-3p-mediated TLR2/4 signaling cascades involving the nuclear factor-kappaB (NF-kappaB), c-Jun NH2-terminal kinase (JNK)/p38, and Janus kinase-signal transducer and activator of transcription (JAK/STAT) pathways in AMs but also ameliorated CS/LPS-induced AM activation and pulmonary inflammation. Our study revealed that miR-27-3p mediated AM activation by the inhibition of PPARgamma activation and sensitization of TLR signaling. PMID- 29572386 TI - Marauding terrorist attack (MTA): prehospital considerations. AB - Terrorist attacks are increasing each year as are the number of deaths associated with them. Recent incidents have seen a shift in tactics with the use of multiple terrorists across multiple locations with firearms or knives, referred to as the marauding terrorist attack. These methods are becoming more prevalent alongside the use of vehicles deliberately aimed at pedestrians. Management of these incidents can be challenging. Not only it involves a large number of casualties but also the management of a dynamic scene in terms of both location and threat from attack. In order to improve response, and potentially outcomes, a system or response needs to have preplanned and practised procedures in place. This article reviews major incident management for those unfamiliar with current prehospital practice and details some of the findings from recent marauding terrorist firearm attacks, in particular the evolution of newer scene management tools such as 3 Echo and THREAT. It highlights the importance of haemorrhage control and the public initiatives focusing on actions during a terrorist incident. PMID- 29572387 TI - Automatic classification of ovarian cancer types from cytological images using deep convolutional neural networks. AB - Ovarian cancer is one of the most common gynecologic malignancies. Accurate classification of ovarian cancer types (serous carcinoma, mucous carcinoma, endometrioid carcinoma, transparent cell carcinoma) is an essential part in the different diagnosis. Computer-aided diagnosis (CADx) can provide useful advice for pathologists to determine the diagnosis correctly. In our study, we employed a Deep Convolutional Neural Networks (DCNN) based on AlexNet to automatically classify the different types of ovarian cancers from cytological images. The DCNN consists of five convolutional layers, three max pooling layers, and two full reconnect layers. Then we trained the model by two group input data separately, one was original image data and the other one was augmented image data including image enhancement and image rotation. The testing results are obtained by the method of 10-fold cross-validation, showing that the accuracy of classification models has been improved from 72.76 to 78.20% by using augmented images as training data. The developed scheme was useful for classifying ovarian cancers from cytological images. PMID- 29572388 TI - Unexpected role of the L-domain of calpastatin during the autoproteolytic activation of human erythrocyte calpain. AB - Autoproteolysis of human erythrocyte calpain-1 proceeds in vitro at high [Ca2+], through the conversion of the 80-kDa catalytic subunit into a 75-kDa activated enzyme that requires lower [Ca2+] for catalysis. Importantly, here we detect a similar 75 kDa calpain-1 form also in vivo, in human meningiomas. Although calpastatin is so far considered the specific inhibitor of calpains, we have previously identified in rat brain a calpastatin transcript truncated at the end of the L-domain (cast110, L-DOM), coding for a protein lacking the inhibitory units. Aim of the present study was to characterize the possible biochemical role of the L-DOM during calpain-1 autoproteolysis in vitro, at high (100 uM) and low (5 uM) [Ca2+]. Here we demonstrate that the L-DOM binds the 80 kDa proenzyme in the absence of Ca2+ Consequently, we have explored the ability of the 75 kDa activated protease to catalyze at 5 uM Ca2+ the intermolecular activation of native calpain-1 associated with the L-DOM. Notably, this [Ca2+] is too low to promote the autoproteolytic activation of calpain-1 but enough to support the catalysis of the 75 kDa calpain. We show for the first time that the L-DOM preserves native calpain-1 from the degradation mediated by the 75 kDa form. Taken together, our data suggest that the free L-domain of calpastatin is a novel member of the calpain/calpastatin system endowed with a function alternative to calpain inhibition. For this reason, it will be crucial to define the intracellular relevance of the L-domain in controlling calpain activation/activity in physiopathological conditions having altered Ca2+ homeostasis. PMID- 29572389 TI - Nicotine enhances mesangial cell proliferation and fibronectin production in high glucose milieu via activation of Wnt/beta-catenin pathway. AB - Diabetic nephropathy (DN) is a major complication of diabetes mellitus. Clinic reports indicate cigarette smoking is an independent risk factor for chronic kidney disease including DN; however, the underlying molecular mechanisms are not clear. Recent studies have demonstrated that nicotine, one of the active compounds in cigarette smoke, contributes to the pathogenesis of the cigarette smoking-accelerated chronic kidney disease. One of the characteristics of DN is the expansion of mesangium, a precursor of glomerular sclerosis. In the present study, we examined the involvement of Wnt/beta-catenin pathway in nicotine mediated mesangial cell growth in high glucose milieu. Primary human renal mesangial cells were treated with nicotine in the presence of normal (5 mM) or high glucose (30 mM) followed by evaluation for cell growth. In the presence of normal glucose, nicotine increased both the total cell numbers and Ki-67 positive cell ratio, indicating that nicotine stimulated mesangial cell proliferation. Although high glucose itself also stimulated mesangial cell proliferation, nicotine further enhanced the mitogenic effect of high glucose. Similarly, nicotine increased the expression of Wnts, beta-catenin, and fibronectin in normal glucose medium, but further increased mesangial cell expression of these proteins in high glucose milieu. Pharmacological inhibition or genetic knockdown of beta-catenin activity or expression with specific inhibitor FH535 or siRNA significantly impaired the nicotine/glucose-stimulated cell proliferation and fibronectin production. We conclude that nicotine may enhance renal mesangial cell proliferation and fibronectin production under high glucose milieus partly through activating Wnt/beta-catenin pathway. Our study provides insight into molecular mechanisms involved in DN. PMID- 29572390 TI - METHIONINE ADENOSYLTRANSFERASE4 Mediates DNA and Histone Methylation. AB - DNA and histone methylation coregulate heterochromatin formation and gene silencing in animals and plants. To identify factors involved in maintaining gene silencing, we conducted a forward genetic screen for mutants that release the silenced transgene Pro35S::NEOMYCIN PHOSPHOTRANSFERASE II in the transgenic Arabidopsis (Arabidopsis thaliana) line L119 We identified MAT4/SAMS3/MTO3/AT3G17390, which encodes methionine (Met) adenosyltransferase 4 (MAT4)/S-adenosyl-Met synthetase 3 that catalyzes the synthesis of S-adenosyl-Met (SAM) in the one-carbon metabolism cycle. mat4 mostly decreases CHG and CHH DNA methylation and histone H3K9me2 and reactivates certain silenced transposons. The exogenous addition of SAM partially rescues the epigenetic defects of mat4 SAM content and DNA methylation were reduced more in mat4 than in three other mat mutants. MAT4 knockout mutations generated by CRISPR/Cas9 were lethal, indicating that MAT4 is an essential gene in Arabidopsis. MAT1, 2, and 4 proteins exhibited nearly equal activity in an in vitro assay, whereas MAT3 exhibited higher activity. The native MAT4 promoter driving MAT1, 2, and 3 cDNA complemented the mat4 mutant. However, most mat4 transgenic lines carrying native MAT1, 2, and 3 promoters driving MAT4 cDNA did not complement the mat4 mutant because of their lower expression in seedlings. Genetic analyses indicated that the mat1mat4 double mutant is dwarfed and the mat2mat4 double mutant was nonviable, while mat1mat2 showed normal growth and fertility. These results indicate that MAT4 plays a predominant role in SAM production, plant growth, and development. Our findings provide direct evidence of the cooperative actions between metabolism and epigenetic regulation. PMID- 29572391 TI - Infusion of donor-derived CD8+ memory T cells for relapse following allogeneic hematopoietic cell transplantation. AB - Murine models showed that CD8+CD44hi memory T (TM) cells could eradicate malignant cells without inducing graft-versus-host disease (GVHD). We evaluated the feasibility and safety of infusing freshly isolated and purified donor derived phenotypic CD8+ TM cells into adults with disease relapse after allogeneic hematopoietic cell transplantation (HCT). Phenotypic CD8 TM cells were isolated after unmobilized donor apheresis using a tandem immunomagnetic selection strategy of CD45RA depletion followed by CD8+ enrichment. Fifteen patients received CD8+ TM cells at escalating doses (1 * 106, 5 * 106, or 10 * 106 cells per kg). Thirteen received cytoreduction before CD8+ TM cell infusion, and 9 had active disease at the time of infusion. Mean yield and purity of the CD8+ TM infusion were 38.1% and 92.8%, respectively; >90% had CD8+ T effector memory phenotype, cytokine expression, and secretion profile. No adverse infusional events or dose-limiting toxicities occurred; GVHD developed in 1 patient (grade 2 liver). Ten patients (67%) maintained or achieved response (7 complete response, 1 partial response, 2 stable disease) for at least 3 months after infusion; 4 of the responders had active disease at the time of infusion. With a median follow-up from infusion of 328 days (range, 118-1328 days), median event-free survival and overall survival were 4.9 months (95% confidence interval [CI], 1-19.3 months) and 19.6 months (95% CI, 5.6 months to not reached), respectively. Collection and enrichment of phenotypic CD8+ TM cells is feasible, well tolerated, and associated with a low incidence of GVHD when administered as a manipulated infusion of donor lymphocytes in patients who have relapsed after HCT. This trial was registered at www.clinicaltrials.gov as #NCT01523223. PMID- 29572392 TI - 'And you'll suddenly realise 'I've not washed my hands': medical students', junior doctors' and medical educators' narratives of hygiene behaviours. AB - OBJECTIVE: Compliance to hygiene behaviours has long been recognised as important in the prevention and control of healthcare associated infections, but medical doctors still display some of the lowest rates of compliance of all healthcare workers. We aim to understand compliance to hygiene behaviours by analysing medical students', junior doctors' and medical educators' narratives of these behaviours to identify their respective attitudes and beliefs around compliance and how these are learnt during training. Such an understanding can inform future interventions to improve compliance targeted to areas of greatest need. DESIGN: A qualitative study, using narrative interviews (nine focus groups and one individual interview). Data were analysed thematically using inductive framework analysis. SETTING: Teaching hospitals in the UK. PARTICIPANTS: Convenience sample of 25 participants: third-year medical students in their first clinical year (n=13), junior doctors (n=6) and medical educators (n=6). RESULTS: We identified four main themes: (1) knowledge, (2) constraints, (3) role models/culture and (4) hygiene as an added extra. Knowledge varied across participant groups and appeared to influence behaviours; medical students relied on what they have been told by seniors, while medical educators relied on their own knowledge and experience. There was a strong belief that evidence for the effectiveness of good hygiene behaviours is lacking. Furthermore, medical educators' behaviour appears to strongly influence others. Finally, hygiene was predominately viewed as an added extra rather than an integral part of the process. CONCLUSIONS: Awareness of the evidence around good hygiene needs to be improved at all levels. Medical students and junior doctors should be encouraged to consider why they are asked to perform certain hygiene behaviours in order to improve ownership of those behaviours. Medical educators need to recognise their responsibilities as role models for their junior counterparts, thereby understanding their role in developing the culture of hygiene practices within their clinical domains. PMID- 29572393 TI - Comparative analysis of methods for identifying multimorbidity patterns: a study of 'real-world' data. AB - OBJECTIVE: The aim was to compare multimorbidity patterns identified with the two most commonly used methods: hierarchical cluster analysis (HCA) and exploratory factor analysis (EFA) in a large primary care database. Specific objectives were: (1) to determine whether choice of method affects the composition of these patterns and (2) to consider the potential application of each method in the clinical setting. DESIGN: Cross-sectional study. Diagnoses were based on the 263 corresponding blocks of the International Classification of Diseases version 10. Multimorbidity patterns were identified using HCA and EFA. Analysis was stratified by sex, and results compared for each method. SETTING AND PARTICIPANTS: Electronic health records for 408 994 patients with multimorbidity aged 45-64 years in 274 primary health care teams from 2010 in Catalonia, Spain. RESULTS: HCA identified 53 clusters for women, with just 12 clusters including at least 2 diagnoses, and 15 clusters for men, all of them including at least two diagnoses. EFA showed 9 factors for women and 10 factors for men. We observed differences by sex and method of analysis, although some patterns were consistent. Three combinations of diseases were observed consistently across sex groups and across both methods: hypertension and obesity, spondylopathies and deforming dorsopathies, and dermatitis eczema and mycosis. CONCLUSIONS: This study showed that multimorbidity patterns vary depending on the method of analysis used (HCA vs EFA) and provided new evidence about the known limitations of attempts to compare multimorbidity patterns in real-world data studies. We found that EFA was useful in describing comorbidity relationships and HCA could be useful for in-depth study of multimorbidity. Our results suggest possible applications for each of these methods in clinical and research settings, and add information about some aspects that must be considered in standardisation of future studies: spectrum of diseases, data usage and methods of analysis. PMID- 29572394 TI - Effectiveness of a chronic obstructive pulmonary disease integrated care pathway in a regional health system: a propensity score matched cohort study. AB - OBJECTIVE: The chronic obstructive pulmonary disease (COPD) integrated care pathway (ICP) programme was designed and implemented to ensure that the care for patients with COPD is comprehensive and integrated across different care settings from primary care to acute hospital and home. We evaluated the effectiveness of the ICP programme for patients with COPD. DESIGN, SETTING AND PARTICIPANTS: A retrospective propensity score matched cohort study was conducted comparing differences between programme enrolees and propensity-matched non-enrolees in a Regional Health System in Singapore. Data on patients diagnosed with COPD who enrolled in the programme (n=95) and patients who did not enrol (n=6330) were extracted from the COPD registry and hospital administrative databases. Enrolees and non-enrolees were propensity score matched. OUTCOME MEASURES: The risk of COPD hospitalisations and COPD hospital bed days savings were compared between the groups using a difference-in-difference strategy and generalised estimating equation approach. Adherence with recommended care elements for the COPD-ICP group was measured quarterly at baseline and during a 2-year follow-up period. RESULTS: Compared with non-enrolees, COPD hospitalisation risk for ICP programme enrolees was significantly lower in year 2 (incidence rate ratio (IRR): 0.73; 95% CI 0.54 to 1.00). Similarly, COPD hospital bed days was significantly lower for enrolees in year 2 (IRR: 0.78; 95% CI 0.64 to 0.95). ICP programme patients had sustained improvements in compliance with all recommended care elements for patients with COPD. The overall all-or-none care bundle compliance rate had improved from 28% to 54%. CONCLUSION: The study concluded that the COPD-ICP programme was associated with reductions in COPD hospitalisation risk and COPD health utilisation in a 2-year follow-up period. PMID- 29572396 TI - Are methodological quality and completeness of reporting associated with citation based measures of publication impact? A secondary analysis of a systematic review of dementia biomarker studies. AB - OBJECTIVE: To determine whether methodological and reporting quality are associated with surrogate measures of publication impact in the field of dementia biomarker studies. METHODS: We assessed dementia biomarker studies included in a previous systematic review in terms of methodological and reporting quality using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) and Standards for Reporting of Diagnostic Accuracy (STARD), respectively. We extracted additional study and journal-related data from each publication to account for factors shown to be associated with impact in previous research. We explored associations between potential determinants and measures of publication impact in univariable and stepwise multivariable linear regression analyses. OUTCOME MEASURES: We aimed to collect data on four measures of publication impact: two traditional measures average number of citations per year and 5-year impact factor of the publishing journal and two alternative measures-the Altmetric Attention Score and counts of electronic downloads. RESULTS: The systematic review included 142 studies. Due to limited data, Altmetric Attention Scores and electronic downloads were excluded from the analysis, leaving traditional metrics as the only analysed outcome measures. We found no relationship between QUADAS and traditional metrics. Citation rates were independently associated with 5-year journal impact factor (beta=0.42; p<0.001), journal subject area (beta=0.39; p<0.001), number of years since publication (beta=-0.29; p<0.001) and STARD (beta=0.13; p<0.05). Independent determinants of 5-year journal impact factor were citation rates (beta=0.45; p<0.001), statement on conflict of interest (beta=0.22; p<0.01) and baseline sample size (beta=0.15; p<0.05). CONCLUSIONS: Citation rates and 5-year journal impact factor appear to measure different dimensions of impact. Citation rates were weakly associated with completeness of reporting, while neither traditional metric was related to methodological rigour. Our results suggest that high publication usage and journal outlet is not a guarantee of quality and readers should critically appraise all papers regardless of presumed impact. PMID- 29572395 TI - Opportunities for better value wound care: a multiservice, cross-sectional survey of complex wounds and their care in a UK community population. AB - BACKGROUND: Complex wounds impose a substantial health economic burden worldwide. As wound care is managed across multiple settings by a range of healthcare professionals with varying levels of expertise, the actual care delivered can vary considerably and result in the underuse of evidence-based interventions, the overuse of interventions supported by limited evidence and low value healthcare. OBJECTIVES: To quantify the number, type and management of complex wounds being treated over a two-week period and to explore variations in care by comparing current practices in wound assessment, prevention and treatment. DESIGN: A multiservice cross-sectional survey. SETTING: This survey spanned eight community services within five Northern England NHS Trusts. RESULTS: The point prevalence of complex wounds in this community-based population was 16.4 per 10 000 (95% CI 15.9 to 17.0). Based on data from 3179 patients, antimicrobial dressings were being used as the primary dressing for 36% of patients with complex wounds. Forty per cent of people with leg ulcers either had not received the recommended Doppler-aided Ankle Brachial Pressure Index assessment or it was unclear whether a recording had been taken. Thirty-one per cent of patients whose most severe wound was a venous leg ulcer were not receiving compression therapy, and there was limited use of two-layer compression hosiery. Of patients with a pressure ulcer, 39% were not using a pressure-relieving cushion or mattress. CONCLUSIONS: Marked variations were found in care, underuse of evidence-based practices and overuse of practices that are not supported by robust research evidence. Significant opportunities for delivering better value wound care therefore exist. Efforts should now focus on developing strategies to identify, assess and disinvest from products and practices supported by little or no evidence and enhance the uptake of those that are. PMID- 29572397 TI - A systematic review of interventions to support the careers of women in academic medicine and other disciplines. AB - OBJECTIVE: To summarise quantitative evaluations of interventions designed to support the careers of women in academia of any discipline. METHOD: A systematic search of English entries in PubMed, CINAHL and Google Scholar was conducted in September 2017. Methodological quality of the studies was independently assessed by two authors using the Joanna Briggs Institute quality appraisal checklists. Meta-analysis was not possible due to heterogeneity in methods and outcomes; results were synthesised and displayed narratively. RESULTS: Eighteen eligible studies were identified, mostly evaluating programmes in academic medicine departments. The most common interventions were mentoring, education, professional development and/or networking programmes. All programmes took a 'bottom-up' approach in that women were responsible for opting into and devoting time to participation. Study quality was low overall, but all studies reported positive outcomes on at least one indicator. Most often this included improvements in self-rated skills and capabilities, or satisfaction with the programme offered. Results regarding tangible outcomes were mixed; while some studies noted improvements in promotion, retention and remuneration, others did not. CONCLUSIONS: This review suggests that targeted programmes have the potential to improve some outcomes for women in academia. However, the studies provide limited high-quality evidence to provide information for academic institutions in terms of the best way to improve outcomes for women in academia. The success of an intervention appears to be undermined when it relies on the additional labour of those it is intending to support (ie, 'bottom-up' approaches). As such, academic institutions should consider and evaluate the efficacy of 'top-down' interventions that start with change in practice of higher management. PMID- 29572398 TI - Frequency of reporting on patient and public involvement (PPI) in research studies published in a general medical journal: a descriptive study. AB - OBJECTIVES: While documented plans for patient and public involvement (PPI) in research are required in many grant applications, little is known about how frequently PPI occurs in practice. Low levels of reported PPI may mask actual activity due to limited PPI reporting requirements. This research analysed the frequency and types of reported PPI in the presence and absence of a journal requirement to include this information. DESIGN AND SETTING: A before and after comparison of PPI reported in research papers published in The BMJ before and 1 year after the introduction of a journal policy requiring authors to report if and how they involved patients and the public within their papers. RESULTS: Between 1 June 2013 and 31 May 2014, The BMJ published 189 research papers and 1 (0.5%) reported PPI activity. From 1 June 2015 to 31 May 2016, following the introduction of the policy, The BMJ published 152 research papers of which 16 (11%) reported PPI activity. Patients contributed to grant applications in addition to designing studies through to coauthorship and participation in study dissemination. Patient contributors were often not fully acknowledged; 6 of 17 (35%) papers acknowledged their contributions and 2 (12%) included them as coauthors. CONCLUSIONS: Infrequent reporting of PPI activity does not appear to be purely due to a failure of documentation. Reporting of PPI activity increased after the introduction of The BMJ's policy, but activity both before and after was low and reporting was inconsistent in quality. Journals, funders and research institutions should collaborate to move us from the current situation where PPI is an optional extra to one where PPI is fully embedded in practice throughout the research process.

AB - OBJECTIVE: Cardiovascular risk factors are associated with primary open-angle glaucoma (POAG) in the general population. However, long-term mortality and major kidney events in patients with new-onset POAG remain unclear. METHODS: Using the Taiwan National Health Insurance Research Database between 1997 and 2011, 15 185 patients with a new diagnosis of POAG were enrolled and propensity score matched (1:1) with 15 185 patients without ocular disorders (WODs). All-cause mortality and major kidney events were analysed by a multivariate Cox proportional hazards regression model and a competing risk regression model. RESULTS: The risk of all cause mortality was significantly higher in patients with new-onset POAG than in those WODs (adjusted HR (aHR) 2.11, 95% CI 1.76 to 2.54; p<0.001). Patients with POAG had higher risks of acute renal failure (ARF) (competing risk aHR 2.58, 95% CI 1.88 to 3.55; p<0.001) and end-stage renal disease (ESRD) (competing risk aHR 4.84, 95% CI 3.02 to 7.77; p<0.001) than those WODs. CONCLUSIONS: Our data demonstrate that POAG is a risk of all-cause mortality, ARF and ESRD, thus needing to notice mortality and major kidney events in patients with new-onset POAG.

AB - INTRODUCTION: For patients with advanced cancer, research shows that pain is frequent, burdensome and undertreated. Evidence-based approaches to support cancer pain management have been developed but have not been implemented within the context of the UK National Health Service. This protocol is for a pragmatic multicentre randomised controlled trial (RCT) to assess feasibility, acceptability, effectiveness and cost-effectiveness for a multicomponent intervention for pain management in patients with advanced cancer. METHODS AND ANALYSIS: This trial will assess the feasibility of implementation and uptake of evidence-based interventions, developed and piloted as part of the Improving the Management of Pain from Advanced Cancer in the Community Programme grant, into routine clinical practice and determine whether there are potential differences with respect to patient-rated pain, patient pain knowledge and experience, healthcare use, quality of life and cost-effectiveness. 160 patients will receive either the intervention (usual care plus supported self-management) delivered within the oncology clinic and palliative care services by locally assigned community palliative care nurses, consisting of a self-management educational intervention and eHealth intervention for routine pain assessment and monitoring; or usual care. The primary outcomes are to assess implementation and uptake of the interventions, and differences in terms of pain severity. Secondary outcomes include pain interference, participant pain knowledge and experience, and cost effectiveness. Outcome assessment will be blinded and patient-reported outcome measures collected via post at 6 and 12 weeks following randomisation. ETHICS AND DISSEMINATION: This RCT has the potential to significantly influence National Health Service delivery to community-based patients with pain from advanced cancer. We aim to provide definitive evidence of whether two simple interventions delivered by community palliative care nurse in palliative care that support-self management are clinically effective and cost-effective additions to standard community palliative care.

PMID- 29572403 TI - Genome-Wide Mapping of DNA Accessibility and Binding Sites for CREB and C/EBPbeta in Vasopressin-Sensitive Collecting Duct Cells. AB - Background Renal water excretion is controlled by vasopressin, in part through regulation of the transcription of the aquaporin-2 gene (Aqp2).Methods To identify enhancer regions likely to be involved in the regulation of Aqp2 and other principal cell-specific genes, we used several next generation DNA sequencing techniques in a well characterized cultured cell model of collecting duct principal cells (mpkCCD). To locate enhancers, we performed the assay for transposase-accessible chromatin using sequencing (ATAC-Seq) to identify accessible regions of DNA and integrated the data with data generated by chromatin immunoprecipitation followed by next generation DNA-sequencing (ChIP Seq) for CCCTC binding factor (CTCF) binding, histone H3 lysine-27 acetylation, and RNA polymerase II.Results We identified two high-probability enhancers centered 81 kb upstream and 5.8 kb downstream from the Aqp2 transcriptional start site. Motif analysis of these regions and the Aqp2 promoter identified several potential transcription factor binding sites, including sites for two b-ZIP transcription factors: CCAAT/enhancer binding protein-beta (C/EBPbeta) and cAMP responsive element binding protein (CREB). To identify genomic binding sites for both, we conducted ChIP-Seq using well characterized antibodies. In the presence of vasopressin, C/EBPbeta, a pioneer transcription factor critical to cell specific gene expression, bound strongly at the identified enhancer downstream from Aqp2 However, over multiple replicates, we found no detectable CREB binding sites within 390 kb of Aqp2 Thus, any role for CREB in the regulation of Aqp2 gene transcription is likely to be indirect.Conclusions The analysis identified two enhancer regions pertinent to transcriptional regulation of the Aqp2 gene and showed C/EBPbeta (but not CREB) binding. PMID- 29572404 TI - Similar Biophysical Abnormalities in Glomeruli and Podocytes from Two Distinct Models. AB - Background FSGS is a pattern of podocyte injury that leads to loss of glomerular function. Podocytes support other podocytes and glomerular capillary structure, oppose hemodynamic forces, form the slit diaphragm, and have mechanical properties that permit these functions. However, the biophysical characteristics of glomeruli and podocytes in disease remain unclear.Methods Using microindentation, atomic force microscopy, immunofluorescence microscopy, quantitative RT-PCR, and a three-dimensional collagen gel contraction assay, we studied the biophysical and structural properties of glomeruli and podocytes in chronic (Tg26 mice [HIV protein expression]) and acute (protamine administration [cytoskeletal rearrangement]) models of podocyte injury.Results Compared with wild-type glomeruli, Tg26 glomeruli became progressively more deformable with disease progression, despite increased collagen content. Tg26 podocytes had disordered cytoskeletons, markedly abnormal focal adhesions, and weaker adhesion; they failed to respond to mechanical signals and exerted minimal traction force in three-dimensional collagen gels. Protamine treatment had similar but milder effects on glomeruli and podocytes.Conclusions Reduced structural integrity of Tg26 podocytes causes increased deformability of glomerular capillaries and limits the ability of capillaries to counter hemodynamic force, possibly leading to further podocyte injury. Loss of normal podocyte mechanical integrity could injure neighboring podocytes due to the absence of normal biophysical signals required for podocyte maintenance. The severe defects in podocyte mechanical behavior in the Tg26 model may explain why Tg26 glomeruli soften progressively, despite increased collagen deposition, and may be the basis for the rapid course of glomerular diseases associated with severe podocyte injury. In milder injury (protamine), similar processes occur but over a longer time. PMID- 29572406 TI - Is routine measurement of TSH in hospitalized patients necessary? AB - TSH routine testing in hospitalized patients has low efficacy, but may be beneficial in a selected subgroup of patients. Our aim was to evaluate the efficacy of routine thyroid function tests among patients admitted to internal medicine departments. It is a retrospective study. A randomly selected cohort of hospitalized patients with abnormal thyroid-stimulating hormone (TSH) blood tests drawn as part of admission protocol. Patient data were collected from the electronic medical files and analyzed for its efficacy. TSH as a screening test was proven unnecessary in 75% (174) of the study population. Leading causes were non-thyroidal illness syndrome, drugs affecting the test results and subclinical disorders. TSH testing was found to be clinically helpful in only 9 patients; however, all of them had other clinical need for TSH testing. We found a clinically abnormal TSH in 20 patients, hypothyroidism in 11 patients and thyrotoxicosis in 9 patients. Low efficacy ascribed to TSH screening test by this study correlates with recent recommendations that indicate TSH screening in admitted patients only with accompanying clinical suspicion. Most probably, the majority of patients found by screening to have thyrotoxicosis have non-thyroidal illness or drug effects so the threshold for FT4 to diagnose overt thyrotoxicosis should be higher than that in ambulatory patients. In elderly patients, clinically relevant TSH disturbances are more frequent and are harder to diagnose, therefore, TSH screening in this group of patients might be beneficial.

AB - This review covers recent findings on the main categories of thyroid hormone disrupting chemicals and their effects on brain development. We draw mostly on epidemiological and experimental data published in the last decade. For each chemical class considered, we deal with not only the thyroid hormone-disrupting effects but also briefly mention the main mechanisms by which the same chemicals could modify estrogen and/or androgen signalling, thereby exacerbating adverse effects on endocrine-dependent developmental programmes. Further, we emphasize recent data showing how maternal thyroid hormone signalling during early pregnancy affects not only offspring IQ, but also neurodevelopmental disease risk. These recent findings add to established knowledge on the crucial importance of iodine and thyroid hormone for optimal brain development. We propose that prenatal exposure to mixtures of thyroid hormone-disrupting chemicals provides a plausible biological mechanism contributing to current increases in the incidence of neurodevelopmental disease and IQ loss.

PMID- 29572427 TI - Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells. AB - Hair curvature underpins structural diversity and function in mammalian coats, but what causes curl in keratin hair fibres? To obtain structural data to determine one aspect of this question, we used confocal microscopy to provide in situ measurements of the two cell types that make up the cortex of merino wool fibres, which was chosen as a well-characterised model system representative of narrow diameter hairs, such as underhairs. We measured orthocortical and paracortical cross-sectional areas, and cortical cell lengths, within individual fibre snippets of defined uniplanar curvature. This allowed a direct test of two long-standing theories of the mechanism of curvature in hairs. We found evidence contradicting the theory that curvature results from there being more cells on the side of the fibre closest to the outside, or convex edge, of curvature. In all cases, the orthocortical cells close to the outside of curvature were longer than paracortical cells close to the inside of the curvature, which supports the theory that curvature is underpinned by differences in cell type length. However, the latter theory also implies that, for all fibres, curvature should correlate with the proportions of orthocortical and paracortical cells, and we found no evidence for this. In merino wool, it appears that the absolute length of cells of each type and proportion of cells varies from fibre to fibre, and only the difference between the length of the two cell types is important. Implications for curvature in higher diameter hairs, such as guard hairs and those on the human scalp, are discussed. PMID- 29572428 TI - Structure of a monolayer of molecular rotors on aqueous subphase from grazing incidence X-ray diffraction. AB - In situ grazing-incidence X-ray scattering shows that a monolayer of artificial rod-shaped dipolar molecular rotors produced on the surface of an aqueous subphase in a Langmuir trough has a structure conducive to a 2D ferroelectric phase. The axes of the rotors stand an average of 0.83 nm apart in a triangular grid, perpendicular to the surface within experimental error. They carry 2,3 dichlorophenylene rotators near rod centers, between two decks of interlocked triptycenes installed axially on the rotor axle. The analysis is based first on simultaneous fitting of observed Bragg rods and second on fitting the reflectivity curve with only three adjustable parameters and the calculated rotor electron density, which also revealed the presence of about seven molecules of water near each rotator. Dependent on preparation conditions, a minor and variable amount of a different crystal phase may also be present in the monolayer. PMID- 29572429 TI - Catalyst design by scanning probe block copolymer lithography. AB - Scanning probe block copolymer lithography (SPBCL), in combination with density functional theory (DFT), has been used to design and synthesize hydrogen evolution catalysts. DFT was used to calculate the hydrogen adsorption energy on a series of single-element, bimetallic, and trimetallic (Au, Pt, Ni, and Cu) substrates to provide leads that could be synthesized in the form of alloy or phase-separated particles via SPBCL. PtAuCu (18 nm, ~1:1:1 stoichiometry) has been identified as a homogeneous alloy phase that behaves as an effective hydrogen evolution catalyst in acidic aqueous media, even when it is made in bulk form via solution phase methods. Significantly, the bulk-prepared PtAuCu/C nanocatalyst discovered via this process exhibits an activity seven times higher than that of the state-of-the-art commercial Pt/C catalyst (based upon Pt content). The advantage of using SPBCL in the discovery process is that one can uniformly make particles, each consisting of a uniform phase combination (e.g., all alloy or all phase-segregated species) at a fixed elemental ratio, an important consideration when working with polyelemental species where multiple phases may exist. PMID- 29572432 TI - Cell-Type-Specific Shank2 Deletion in Mice Leads to Differential Synaptic and Behavioral Phenotypes. AB - Shank2 is an excitatory postsynaptic scaffolding protein implicated in synaptic regulation and psychiatric disorders including autism spectrum disorders. Conventional Shank2-mutant (Shank2-/-) mice display several autistic-like behaviors, including social deficits, repetitive behaviors, hyperactivity, and anxiety-like behaviors. However, cell-type-specific contributions to these behaviors have remained largely unclear. Here, we deleted Shank2 in specific cell types and found that male mice lacking Shank2 in excitatory neurons (CaMKII Cre;Shank2fl/fl) show social interaction deficits and mild social communication deficits, hyperactivity, and anxiety-like behaviors. In particular, male mice lacking Shank2 in GABAergic inhibitory neurons (Viaat-Cre;Shank2fl/fl) display social communication deficits, repetitive self-grooming, and mild hyperactivity. These behavioral changes were associated with distinct changes in hippocampal and striatal synaptic transmission in the two mouse lines. These results indicate that cell-type-specific deletions of Shank2 in mice lead to differential synaptic and behavioral abnormalities.SIGNIFICANCE STATEMENT Shank2 is an abundant excitatory postsynaptic scaffolding protein implicated in the regulation of excitatory synapses and diverse psychiatric disorders including autism spectrum disorders. Previous studies have reported in vivo functions of Shank2 mainly using global Shank2-null mice, but it remains largely unclear how individual cell types contribute to Shank2-dependent regulation of neuronal synapses and behaviors. Here, we have characterized conditional Shank2-mutant mice carrying the Shank2 deletion in excitatory and inhibitory neurons. These mouse lines display distinct alterations of synaptic transmission in the hippocampus and striatum that are associated with differential behavioral abnormalities in social, repetitive, locomotor, and anxiety-like domains. PMID- 29572431 TI - A Gain-of-Function Mutation in the alpha9 Nicotinic Acetylcholine Receptor Alters Medial Olivocochlear Efferent Short-Term Synaptic Plasticity. AB - Gain control of the auditory system operates at multiple levels. Cholinergic medial olivocochlear (MOC) fibers originate in the brainstem and make synaptic contacts at the base of the outer hair cells (OHCs), the final targets of several feedback loops from the periphery and higher-processing centers. Efferent activation inhibits OHC active amplification within the mammalian cochlea, through the activation of a calcium-permeable alpha9alpha10 ionotropic cholinergic nicotinic receptor (nAChR), functionally coupled to calcium activated SK2 potassium channels. Correct operation of this feedback requires careful matching of acoustic input with the strength of cochlear inhibition (Galambos, 1956; Wiederhold and Kiang, 1970; Gifford and Guinan, 1987), which is driven by the rate of MOC activity and short-term facilitation at the MOC-OHC synapse (Ballestero et al., 2011; Katz and Elgoyhen, 2014). The present work shows (in mice of either sex) that a mutation in the alpha9alpha10 nAChR with increased duration of channel gating (Taranda et al., 2009) greatly elongates hair cell evoked IPSCs and Ca2+ signals. Interestingly, MOC-OHC synapses of L9'T mice presented reduced quantum content and increased presynaptic facilitation. These phenotypic changes lead to enhanced and sustained synaptic responses and OHC hyperpolarization upon high-frequency stimulation of MOC terminals. At the cochlear physiology level these changes were matched by a longer time course of efferent MOC suppression. This indicates that the properties of the MOC-OHC synapse directly determine the efficacy of the MOC feedback to the cochlea being a main player in the "gain control" of the auditory periphery.SIGNIFICANCE STATEMENT Plasticity can involve reciprocal signaling across chemical synapses. An opportunity to study this phenomenon occurs in the mammalian cochlea whose sensitivity is regulated by efferent olivocochlear neurons. These release acetylcholine to inhibit sensory hair cells. A point mutation in the hair cell's acetylcholine receptor that leads to increased gating of the receptor greatly elongates IPSCs. Interestingly, efferent terminals from mutant mice present a reduced resting release probability. However, upon high-frequency stimulation transmitter release facilitates strongly to produce stronger and far longer lasting inhibition of cochlear function. Thus, central neuronal feedback on cochlear hair cells provides an opportunity to define plasticity mechanisms in cholinergic synapses other than the highly studied neuromuscular junction. PMID- 29572430 TI - Rlip depletion prevents spontaneous neoplasia in TP53 null mice. AB - TP53 (p53) is a tumor suppressor whose functions are lost or altered in most malignancies. p53 homozygous knockout (p53-/-) mice uniformly die of spontaneous malignancy, typically T-cell lymphoma. RALBP1 (RLIP76, Rlip) is a stress protective, mercapturic acid pathway transporter protein that also functions as a Ral effector involved in clathrin-dependent endocytosis. In stark contrast to p53 /- mice, Rlip-/- mice are highly resistant to carcinogenesis. We report here that partial Rlip deficiency induced by weekly administration of an Rlip-specific phosphorothioate antisense oligonucleotide, R508, strongly inhibited spontaneous as well as benzo(a)pyrene-induced carcinogenesis in p53-/- mice. This treatment effectively prevented large-scale methylomic and transcriptomic abnormalities suggestive of inflammation found in cancer-bearing p53-/- mice. The remarkable efficiency with which Rlip deficiency suppresses spontaneous malignancy in p53-/- mice has not been observed with any previously reported pharmacologic or genetic intervention. These findings are supported by cross-breeding experiments demonstrating that hemizygous Rlip deficiency also reduces the spontaneous malignancy phenotype of p53+/- mice. Rlip is found on the cell surface, and antibodies directed against Rlip were found to inhibit growth and promote apoptosis of cell lines as effectively as Rlip siRNA. The work presented here investigates several features, including oxidative DNA damage of the Rlip-p53 association in malignant transformation, and offers a paradigm for the mechanisms of tumor suppression by p53 and the prospects of suppressing spontaneous malignancy in hereditary cancer syndromes such as Li-Fraumeni. PMID- 29572433 TI - Cholinergic Modulation of Frontoparietal Cortical Network Dynamics Supporting Supramodal Attention. AB - A critical function of attention is to support a state of readiness to enhance stimulus detection, independent of stimulus modality. The nucleus basalis magnocellularis (NBM) is the major source of the neurochemical acetylcholine (ACh) for frontoparietal cortical networks thought to support attention. We examined a potential supramodal role of ACh in a frontoparietal cortical attentional network supporting target detection. We recorded local field potentials (LFPs) in the prelimbic frontal cortex (PFC) and the posterior parietal cortex (PPC) to assess whether ACh contributed to a state of readiness to alert rats to an impending presentation of visual or olfactory targets in one of five locations. Twenty male Long-Evans rats underwent training and then lesions of the NBM using the selective cholinergic immunotoxin 192 IgG-saporin (0.3 MUg/MUl; ACh-NBM-lesion) to reduce cholinergic afferentation of the cortical mantle. Postsurgery, ACh-NBM-lesioned rats had less correct responses and more omissions than sham-lesioned rats, which changed parametrically as we increased the attentional demands of the task with decreased target duration. This parametric deficit was found equally for both sensory targets. Accurate detection of visual and olfactory targets was associated specifically with increased LFP coherence, in the beta range, between the PFC and PPC, and with increased beta power in the PPC before the target's appearance in sham-lesioned rats. Readiness associated changes in brain activity and visual and olfactory target detection were attenuated in the ACh-NBM-lesioned group. Accordingly, ACh may support supramodal attention via modulating activity in a frontoparietal cortical network, orchestrating a state of readiness to enhance target detection.SIGNIFICANCE STATEMENT We examined whether the neurochemical acetylcholine (ACh) contributes to a state of readiness for target detection, by engaging frontoparietal cortical attentional networks independent of modality. We show that ACh supported alerting attention to an impending presentation of either visual or olfactory targets. Using local field potentials, enhanced stimulus detection was associated with an anticipatory increase in power in the beta oscillation range before the target's appearance within the posterior parietal cortex (PPC) as well as increased synchrony, also in beta, between the prefrontal cortex and PPC. These readiness-associated changes in brain activity and behavior were attenuated in rats with reduced cortical ACh. Thus, ACh may act, in a supramodal manner, to prepare frontoparietal cortical attentional networks for target detection. PMID- 29572434 TI - Convergence and Divergence of CRH Amacrine Cells in Mouse Retinal Circuitry. AB - Inhibitory interneurons sculpt the outputs of excitatory circuits to expand the dynamic range of information processing. In mammalian retina, >30 types of amacrine cells provide lateral inhibition to vertical, excitatory bipolar cell circuits, but functional roles for only a few amacrine cells are well established. Here, we elucidate the function of corticotropin-releasing hormone (CRH)-expressing amacrine cells labeled in Cre-transgenic mice of either sex. CRH cells costratify with the ON alpha ganglion cell, a neuron highly sensitive to positive contrast. Electrophysiological and optogenetic analyses demonstrate that two CRH types (CRH-1 and CRH-3) make GABAergic synapses with ON alpha cells. CRH 1 cells signal via graded membrane potential changes, whereas CRH-3 cells fire action potentials. Both types show sustained ON-type responses to positive contrast over a range of stimulus conditions. Optogenetic control of transmission at CRH-1 synapses demonstrates that these synapses are tuned to low temporal frequencies, maintaining GABA release during fast hyperpolarizations during brief periods of negative contrast. CRH amacrine cell output is suppressed by prolonged negative contrast, when ON alpha ganglion cells continue to receive inhibitory input from converging OFF-pathway amacrine cells; the converging ON- and OFF pathway inhibition balances tonic excitatory drive to ON alpha cells. Previously, it was demonstrated that CRH-1 cells inhibit firing by suppressed-by-contrast (SbC) ganglion cells during positive contrast. Therefore, divergent outputs of CRH-1 cells inhibit two ganglion cell types with opposite responses to positive contrast. The opposing responses of ON alpha and SbC ganglion cells are explained by differing excitation/inhibition balance in the two circuits.SIGNIFICANCE STATEMENT A goal of neuroscience research is to explain the function of neural circuits at the level of specific cell types. Here, we studied the function of specific types of inhibitory interneurons, corticotropin-releasing hormone (CRH) amacrine cells, in the mouse retina. Genetic tools were used to identify and manipulate CRH cells, which make GABAergic synapses with a well studied ganglion cell type, the ON alpha cell. CRH cells converge with other types of amacrine cells to tonically inhibit ON alpha cells and balance their high level of excitation. CRH cells diverge to different types of ganglion cell, the unique properties of which depend on their balance of excitation and inhibition. PMID- 29572435 TI - beta-Arrestin 1/2 Aggravates Podocyte Apoptosis of Diabetic Nephropathy via Wnt/beta-Catenin Pathway. AB - BACKGROUND beta-arrestins have been shown to play a critical role in the progression of diabetic nephropathy. Nevertheless, the potential mechanism of beta-arrestins on the regulation of podocyte apoptosis has rarely been discussed. This study aimed to elucidate the regulation of beta-arrestin 1/2 on podocyte apoptosis through the Wnt/b-catenin pathway. MATERIAL AND METHODS This study structured beta-arrestin 1/2 down-regulated and up-regulated expression by plasmid transfection. The protein levels were detected with Western blotting, and mRNA expression was detected with RT-qPCR. The apoptotic cells were measured by flow cytometry. RESULTS beta-arrestin 1/2 expression levels of podocytes were up regulated in high-glucose-induced podocytes. beta-arrestin 1/2 overexpression inhibited the expression of nephrin and podocin protein. Up-regulated beta arrestin 1/2 promoted podocyte apoptosis and p53 pathway by increasing Bax, cleaved caspase-3, and p-p53 levels in high-glucose-induced podocytes. Flow cytometry showed that the apoptotic cells were markedly higher in the b-arrestin 1/2 up-regulated group compared with the scramble group. Expression of beta catenin was increased in the beta-arrestin 1/2 up-regulated group, which indicated that the Wnt/b-catenin pathway was activated. Wnt/b-catenin pathway inhibitor (Dkk1) distinctly suppressed the apoptosis induced by beta-arrestin 1/2 overexpression and high glucose. CONCLUSIONS These results provide a molecular pathomechanism of beta-arrestin 1/2 and Wnt/beta-catenin pathway on podocyte apoptosis and provide new ideas for the treatment of diabetic nephropathy, which paves the way for the future study of diabetic nephropathy and podocytes.

PMID- 29572436 TI - Pulmonary Artery Rupture Management with a Single Lumen Endotracheal Tube: Old Tricks that Should be Revisited. AB - BACKGROUND Pulmonary artery rupture can be a lethal complication of a pulmonary artery catheter (PAC). Different techniques have been used to manage PAC-induced pulmonary artery rupture, including double lumen endotracheal tube (DLT), bronchial blockers, pulmonary artery embolization, thoracotomy with hematoma evacuation, and extracorporeal life support for ventilation (ECLS). Single lumen endotracheal tube (ETT) is not frequently reported in the literature despite its advantages. CASE REPORT The authors present a case of PAC-induced pulmonary artery rupture successfully managed with a single lumen ETT. Although single lumen ETT is more labor intensive and requires constant critical care attention, the advantages of this technique are reported in this case in comparison to other well-documented therapies. CONCLUSIONS With on-going pulmonary bleeding, a single lumen ETT intubation offers advantages to the commonly advocated methods of treating a PAC-induced pulmonary artery rupture. PMID- 29572438 TI - Interruption of lactate uptake by inhibiting mitochondrial pyruvate transport unravels direct antitumor and radiosensitizing effects. AB - Lactate exchange between glycolytic and oxidative cancer cells is proposed to optimize tumor growth. Blocking lactate uptake through monocarboxylate transporter 1 (MCT1) represents an attractive therapeutic strategy but may stimulate glucose consumption by oxidative cancer cells. We report here that inhibition of mitochondrial pyruvate carrier (MPC) activity fulfils the tasks of blocking lactate use while preventing glucose oxidative metabolism. Using in vitro 13C-glucose and in vivo hyperpolarized 13C-pyruvate, we identify 7ACC2 as a potent inhibitor of mitochondrial pyruvate transport which consecutively blocks extracellular lactate uptake by promoting intracellular pyruvate accumulation. Also, while in spheroids MCT1 inhibition leads to cytostatic effects, MPC activity inhibition induces cytotoxic effects together with glycolysis stimulation and uncompensated inhibition of mitochondrial respiration. Hypoxia reduction obtained with 7ACC2 is further shown to sensitize tumor xenografts to radiotherapy. This study positions MPC as a control point for lactate metabolism and expands on the anticancer potential of MPC inhibition.

AB - The originally published version of this Article contained an error in Figure 6. In panel b, the top graph (BrdU 21-24d) and the bottom graph (BrdU 28-31d) were inadvertently swapped. This error has now been corrected in both the PDF and HTML versions of the Article. PMID- 29572440 TI - A biochemical network controlling basal myosin oscillation. AB - The actomyosin cytoskeleton, a key stress-producing unit in epithelial cells, oscillates spontaneously in a wide variety of systems. Although much of the signal cascade regulating myosin activity has been characterized, the origin of such oscillatory behavior is still unclear. Here, we show that basal myosin II oscillation in Drosophila ovarian epithelium is not controlled by actomyosin cortical tension, but instead relies on a biochemical oscillator involving ROCK and myosin phosphatase. Key to this oscillation is a diffusive ROCK flow, linking junctional Rho1 to medial actomyosin cortex, and dynamically maintained by a self activation loop reliant on ROCK kinase activity. In response to the resulting myosin II recruitment, myosin phosphatase is locally enriched and shuts off ROCK and myosin II signals. Coupling Drosophila genetics, live imaging, modeling, and optogenetics, we uncover an intrinsic biochemical oscillator at the core of myosin II regulatory network, shedding light on the spatio-temporal dynamics of force generation.

AB - Following the Permo-Triassic Extinction, large-bodied diapsid reptiles-with a body length >1 m-rapidly expanded their ecological roles. This diversification is reflected in enormous disparity in the development of the rostrum and adductor chamber. However, it is unclear how marked the diversity of the feeding apparatus was in contemporary small-bodied diapsids. Here we describe the remarkably small skull (2.5 cm long) of a saurian reptile, Colobops noviportensis, gen. et sp. nov., from the Triassic New Haven Arkose of Connecticut, USA. The taxon possesses an exceptionally reinforced snout and strikingly expanded supratemporal fossae for adductor musculature relative to any known Mesozoic or Recent diapsid of similar size. Our phylogenetic analyses support C. noviportensis as an early diverging pan-archosaur. Colobops noviportensis reveals extraordinary disparity of the feeding apparatus in small-bodied early Mesozoic diapsids, and a suite of morphologies, functionally related to a powerful bite, unknown in any small bodied diapsid.

AB - The B cell survival factor (TNFSF13B/BAFF) is often elevated in autoimmune diseases and is targeted in the clinic for the treatment of systemic lupus erythematosus. BAFF contains a loop region designated the flap, which is dispensable for receptor binding. Here we show that the flap of BAFF has two functions. In addition to facilitating the formation of a highly active BAFF 60 mer as shown previously, it also converts binding of BAFF to TNFRSF13C (BAFFR) into a signaling event via oligomerization of individual BAFF-BAFFR complexes. Binding and activation of BAFFR can therefore be targeted independently to inhibit or activate the function of BAFF. Moreover, structural analyses suggest that the flap of BAFF 60-mer temporarily prevents binding of an anti-BAFF antibody (belimumab) but not of a decoy receptor (atacicept). The observed differences in profiles of BAFF inhibition may confer distinct biological and clinical efficacies to these therapeutically relevant inhibitors. PMID- 29572443 TI - A neuronal basis for fear discrimination in the lateral amygdala. AB - In the presence of new stimuli, it is crucial for survival to react with defensive responses in the presence of stimuli that resemble threats but also to not react with defensive behavior in response to new harmless stimuli. Here, we show that in the presence of new uncertain stimuli with sensory features that produce an ambiguous interpretation, discriminative processes engage a subset of excitatory and inhibitory neurons within the lateral amygdala (LA) that are partially different from those engaged by fear processes. Inducing the pharmacogenetic deletion of this neuronal ensemble caused fear generalization but left anxiety-like response, fear memory and extinction processes intact. These data reveal that two opposite neuronal processes account for fear discrimination and generalization within the LA and suggest a potential pathophysiological mechanism for the impaired discrimination that characterizes fear-related disorders. PMID- 29572444 TI - Designed heterogeneous palladium catalysts for reversible light-controlled bioorthogonal catalysis in living cells. AB - As a powerful tool for chemical biology, bioorthogonal chemistry broadens the ways to explore the mystery of life. In this field, transition metal catalysts (TMCs) have received much attention because TMCs can rapidly catalyze chemical transformations that cannot be accomplished by bio-enzymes. However, fine controlling chemical reactions in living systems like bio-enzymes is still a great challenge. Herein, we construct a versatile light-controlled bioorthogonal catalyst by modifying macroporous silica-Pd0 with supramolecular complex of azobenzene (Azo) and beta-cyclodextrin (CD). Its catalytic activity can be regulated by light-induced structural changes, mimicking allosteric regulation mechanism of bio-enzymes. The light-gated heterogeneous TMCs are important for in situ controlling bioorthogonal reactions and have been successfully used to synthesize a fluorescent probe for cell imaging and mitochondria-specific targeting agent by Suzuki-Miyaura cross-coupling reaction. Endowing the bioorthogonal catalyst with new functions is highly valuable for realizing more complex researches in biochemistry. PMID- 29572445 TI - Diatom frustules protect DNA from ultraviolet light. AB - The evolutionary causes for generation of nano and microstructured silica by photosynthetic algae are not yet deciphered. Diatoms are single photosynthetic algal cells populating the oceans and waters around the globe. They generate a considerable fraction (20-30%) of all oxygen from photosynthesis, and 45% of total primary production of organic material in the sea. There are more than 100,000 species of diatoms, classified by the shape of the glass cage in which they live, and which they build during algal growth. These glass structures have accumulated for the last 100 million of years, and left rich deposits of nano/microstructured silicon oxide in the form of diatomaceous earth around the globe. Here we show that reflection of ultraviolet light by nanostructured silica can protect the deoxyribonucleic acid (DNA) in the algal cells, and that this may be an evolutionary cause for the formation of glass cages. PMID- 29572446 TI - Transcriptome Profiles Reveal the Crucial Roles of Hormone and Sugar in the Bud Dormancy of Prunus mume. AB - Bud dormancy transition is a vital developmental process for perennial plant survival. The process is precisely regulated by diverse endogenous genetic factors and environmental cues, but the mechanisms are not yet fully understood. Prunus mume is an ideal crop for bud dormancy analysis because of its early spring-flowering characteristics and small sequenced genome. Here, we analyzed the transcriptome profiles at the three endodormancy stages and natural flush stage using RNA sequencing combined with phytohormone and sugar content measurements. Significant alterations in hormone contents and carbohydrate metabolism have been observed, and alpha-amylases, Glucan Hydrolase Family 17 and diphosphate-glycosyltransferase family might play crucial roles in the interactions between hormones and sugars. The following hypothetical model for understanding the molecular mechanism of bud dormancy in Prunus mume is proposed: low temperatures exposure induces the significant up-regulation of eight C-repeat binding factor genes, which directly promotes all six dormancy-associated MADS box genes, resulting in dormancy establishment. The prolonged cold and/or subsequently increasing temperature then decreases the expression levels of these two gene families, which alleviates the inhibition of FLOWERING LOCUS T and reopens the growth-promoting pathway, resulting in dormancy release and the initiation of the bud break process. PMID- 29572447 TI - Coupling of oceanic carbon and nitrogen facilitates spatially resolved quantitative reconstruction of nitrate inventories. AB - Anthropogenic impacts are perturbing the global nitrogen cycle via warming effects and pollutant sources such as chemical fertilizers and burning of fossil fuels. Understanding controls on past nitrogen inventories might improve predictions for future global biogeochemical cycling. Here we show the quantitative reconstruction of deglacial bottom water nitrate concentrations from intermediate depths of the Peruvian upwelling region, using foraminiferal pore density. Deglacial nitrate concentrations correlate strongly with downcore delta13C, consistent with modern water column observations in the intermediate Pacific, facilitating the use of delta13C records as a paleo-nitrate-proxy at intermediate depths and suggesting that the carbon and nitrogen cycles were closely coupled throughout the last deglaciation in the Peruvian upwelling region. Combining the pore density and intermediate Pacific delta13C records shows an elevated nitrate inventory of >10% during the Last Glacial Maximum relative to the Holocene, consistent with a delta13C-based and delta15N-based 3D ocean biogeochemical model and previous box modeling studies. PMID- 29572448 TI - Improvement in the management of chronic obstructive pulmonary disease following a clinical educational program: results from a prospective cohort study in the Sicilian general practice setting. AB - Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder of the lungs associated with progressive disability. Although general practitioners (GPs) should play an important role in the COPD management, critical issues have been documented in the primary care setting. The aim of this study was to evaluate the effectiveness of an educational program for the improvement of the COPD management in a Sicilian general practice setting. The effectiveness of the program, was evaluated by comparing 15 quality-of-care indicators developed from data extracted by 33 GPs, at baseline vs. 12 and 24 months, and compared with data from a national primary care database (HSD). Moreover, data on COPD-related and all-cause hospitalizations over time of COPD patients, was measured. Overall, 1,465 patients (3.2%) had a registered diagnosis of COPD at baseline vs. 1,395 (3.0%) and 1,388 (3.0%) over time (vs. 3.0% in HSD). COPD patients with one spirometry registered increased from 59.7% at baseline to 73.0% after 2 years (vs. 64.8% in HSD). Instead, some quality of care indicators where not modified such as proportion of COPD patients treated with ICS in monotherapy that was almost stable during the study period: 9.6% (baseline) vs. 9.9% (after 2 years), vs. 7.7% in HSD. COPD-related and all-cause hospitalizations of patients affected by COPD decreased during the two observation years (from 6.9% vs. 4.0%; from 23.0% vs. 18.9%, respectively). Our study showed that educational program involving specialists, clinical pharmacologists and GPs based on training events and clinical audit may contribute to partly improve both diagnostic and therapeutic management of COPD in primary care setting, despite this effect may vary across GPs and indicators of COPD quality of care. PMID- 29572449 TI - Genetic markers for urine haptoglobin is associated with decline in renal function in type 2 diabetes in East Asians. AB - Urine haptoglobin (uHP) level prospectively predicts diabetic kidney disease (DKD) progression. Here, we aim to identify genetic determinants of uHP level and evaluate association with renal function in East Asians (EA) with type 2 diabetes (T2D). Genome-wide association study (GWAS) among 805 [236 Chinese (discovery) and 569 (57 Malay and 512 Chinese) (validation)] found that rs75444904/kgp16506790 variant was robustly associated with uHP level (MetaP = 1.21 * 10-60). rs75444904 correlates well with plasma HP protein levels and multimerization in EA but was not in perfect LD (r2 = 0.911 in Chinese, r2 = 0.536 in Malay) and is monomorphic in Europeans (1000 G data). Conditional probability analysis indicated weakening of effects but residual significant associations between rs75444904 and uHP when adjusted on HP structural variant (MetaP = 8.22 * 10-7). The rs75444904 variant was associated with DKD progression (OR = 1.77, P = 0.014) independent of traditional risk factors. In an additional validation-cohort of EA (410 end-stage renal disease (ESRD) cases and 1308 controls), rs75444904 was associated with ESRD (OR = 1.22, P = 0.036). Furthermore, increased risk of DKD progression (OR = 2.09, P = 0.007) with elevated uHP level through Mendelian randomisation analysis provide support for potential causal role of uHP in DKD progression in EA. However, further replication of our findings in larger study populations is warranted. PMID- 29572450 TI - RNA-Seq identifies genes whose proteins are transformative in the differentiation of cytotrophoblast to syncytiotrophoblast, in human primary villous and BeWo trophoblasts. AB - The fusion of villous cytotrophoblasts into the multinucleated syncytiotrophoblast is critical for the essential functions of the mammalian placenta. Using RNA-Seq gene expression and quantitative protein expression, we identified genes and their cognate proteins which are coordinately up- or down regulated in two cellular models of cytotrophoblast to syncytiotrophoblast development, human primary villous and human BeWo cytotrophoblasts. These include hCGbeta, TREML2, PAM, CRIP2, INHA, FLRG, SERPINF1, C17orf96, KRT17 and SAA1. These findings provide avenues for further understanding the mechanisms underlying mammalian placental synctiotrophoblast development. PMID- 29572452 TI - Exact results of the limited penetrable horizontal visibility graph associated to random time series and its application. AB - The limited penetrable horizontal visibility algorithm is an analysis tool that maps time series into complex networks and is a further development of the horizontal visibility algorithm. This paper presents exact results on the topological properties of the limited penetrable horizontal visibility graph associated with independent and identically distributed (i:i:d:) random series. We show that the i.i.d: random series maps on a limited penetrable horizontal visibility graph with exponential degree distribution, independent of the probability distribution from which the series was generated. We deduce the exact expressions of mean degree and clustering coefficient, demonstrate the long distance visibility property of the graph and perform numerical simulations to test the accuracy of our theoretical results. We then use the algorithm in several deterministic chaotic series, such as the logistic map, H'enon map, Lorenz system, energy price chaotic system and the real crude oil price. Our results show that the limited penetrable horizontal visibility algorithm is efficient to discriminate chaos from uncorrelated randomness and is able to measure the global evolution characteristics of the real time series.

AB - Aminoglycosides are commonly used for the treatment of pulmonary exacerbations in patients with cystic fibrosis (CF). However, they are potentially nephrotoxic. This prospective observational cohort study aimed to investigate the potential validity of two urinary renal biomarkers, Kidney Injury Molecule-1 (KIM-1) and Neutrophil Gelatinase-associated Lipocalin (NGAL), in identifying aminoglycoside induced nephrotoxicity in children with CF. Children and young adults up to 20 years of age with a confirmed diagnosis of CF were recruited from ten United Kingdom hospitals. Participants provided urine samples for measurement of KIM-1 and NGAL concentrations, at baseline, at regular outpatient appointments, and before, during and after exposure to clinically-indicated treatment with the aminoglycoside tobramycin. 37/158 patients recruited (23.4%) received at least one course of IV tobramycin during the study. The median peak fold-change during tobramycin exposure for KIM-1 was 2.28 (IQR 2.69) and 4.02 (IQR 7.29) for NGAL, in the absence of serum creatinine changes. Baseline KIM-1 was positively associated with cumulative courses of IV aminoglycosides (R2 = 0.11; beta = 0.03; p < 0.0001). KIM-1, in particular, may be a useful, non-invasive, biomarker of acute and chronic proximal tubular injury associated with exposure to aminoglycosides in patients with CF, but its clinical utility needs to be further evaluated in prospective studies. PMID- 29572453 TI - Floral resource partitioning by individuals within generalised hoverfly pollination networks revealed by DNA metabarcoding. AB - Pollination is a key ecosystem service for agriculture and wider ecosystem function. However, most pollination studies focus on Hymenoptera, with hoverflies (Syrphidae) frequently treated as a single functional group. We tested this assumption by investigating pollen carried by eleven species of hoverfly in five genera, Cheilosia, Eristalis, Rhingia, Sericomyia and Volucella, using DNA metabarcoding. Hoverflies carried pollen from 59 plant taxa, suggesting they visit a wider number of plant species than previously appreciated. Most pollen recorded came from plant taxa frequently found at our study sites, predominantly Apiaceae, Cardueae, Calluna vulgaris, Rubus fruticosus agg., and Succisa pratensis, with hoverflies transporting pollen from 40% of entomophilous plant species present. Overall pollen transport network structures were generalised, similar to other pollination networks elsewhere. All hoverfly species were also generalised with few exclusive plant/hoverfly interactions. However, using the Jaccard Index, we found significant differences in the relative composition of pollen loads between hoverfly genera, except for Volucella, demonstrating some degree of functional complementarity. Eristalis and Sericomyia species had significant differences in relative pollen load composition compared to congeners. Our results demonstrate the range of pollens transported by hoverflies and the potential pollination function undertaken within this ecologically and morphologically diverse guild. PMID- 29572454 TI - First adequately-known quadrupedal sirenian from Eurasia (Eocene, Bay of Biscay, Huesca, northeastern Spain). AB - Sirenians are the only extant herbivorous mammals fully adapted to an aquatic lifestyle. They originated in Africa during the Paleocene from an undetermined clade of afrotherian mammals, and by the end of the Eocene they were widely distributed across the tropical latitudes. Here we introduce Sobrarbesiren cardieli gen. et sp. nov. It is the first adequately-known quadrupedal sirenian from Eurasia and the oldest record of this clade from western Europe. Fossils have been recovered from the middle Lutetian (SBZ15) site of Castejon de Sobrarbe 41 (Huesca, Spain), and comprise many cranial and postcranial remains, including pelvic girdle and hind limb bones, from at least six sirenian individuals of different ontogenetic stages. Sobrarbesiren shows a suite of characters previously considered synapomorphies of different clades of derived sirenians, such as the presence of the processus retroversus of the squamosal and the pterygoid fossa, combined with ancestral characters such as the presence of an alisphenoid canal, a permanent P5, at least two sacral vertebrae, a primitive pelvis and functional femora and fibulae. Sobrarbesiren is recovered as the sister taxon of Dugongidae and represents a transitional stage of adaptation to aquatic life between the amphibious quadrupedal prorastomids and the aquatic quadrupedal protosirenids. PMID- 29572455 TI - Scale-up and large-scale production of Tetraselmis sp. CTP4 (Chlorophyta) for CO2 mitigation: from an agar plate to 100-m3 industrial photobioreactors. AB - Industrial production of novel microalgal isolates is key to improving the current portfolio of available strains that are able to grow in large-scale production systems for different biotechnological applications, including carbon mitigation. In this context, Tetraselmis sp. CTP4 was successfully scaled up from an agar plate to 35- and 100-m3 industrial scale tubular photobioreactors (PBR). Growth was performed semi-continuously for 60 days in the autumn-winter season (17th October - 14th December). Optimisation of tubular PBR operations showed that improved productivities were obtained at a culture velocity of 0.65-1.35 m s 1 and a pH set-point for CO2 injection of 8.0. Highest volumetric (0.08 +/- 0.01 g L-1 d-1) and areal (20.3 +/- 3.2 g m-2 d-1) biomass productivities were attained in the 100-m3 PBR compared to those of the 35-m3 PBR (0.05 +/- 0.02 g L 1 d-1 and 13.5 +/- 4.3 g m-2 d-1, respectively). Lipid contents were similar in both PBRs (9-10% of ash free dry weight). CO2 sequestration was followed in the 100-m3 PBR, revealing a mean CO2 mitigation efficiency of 65% and a biomass to carbon ratio of 1.80. Tetraselmis sp. CTP4 is thus a robust candidate for industrial-scale production with promising biomass productivities and photosynthetic efficiencies up to 3.5% of total solar irradiance. PMID- 29572456 TI - Macular assessment of preoperative optical coherence tomography in ageing Chinese undergoing routine cataract surgery. AB - This retrospective consecutive case series aimed to evaluate spectral-domain optical coherence tomography (SD-OCT) for occult macular disease recognition preoperatively in patients scheduled for routine cataract surgery. All patients scheduled for cataract surgery underwent macular SD-OCT. Scans were reviewed for retinal, retinal pigment epithelium and vitreomacular interface abnormalities. For the subgroup analysis, the following information was collected: age; sex; and diabetes, hypertension, myopia, glaucoma, post intra-ocular surgery, endophotocoagulation, retinal vasculopathy and uveitis statuses. One-thousand-one hundred-seventy-six consecutive scans were acquired from 1,176 patients. Macular pathology was found in 294 eyes. The most common macular disorders were an epiretinal membrane (n = 130), myopia atrophy (n = 61) and a dome-shaped macular with pathologic myopia (n = 32). One-hundred-thirty eyes (11.05%) presented macular epiretinal membranes not detected by dilated fundus examination, accounting for 44.22% of the abnormalities in diseased eyes and was higher than in previous Chinese studies. Some had multiple macular disorders. The most common ocular history was myopia, including high myopia. The pooled prevalence rate of macular diseases detected by OCT was 0.24 (95% CI 0.14-0.34) using meta-analysis. SD-OCT should be performed for routine cataract surgery patients to evaluate visual outcomes, especially in myopic patients and those considering advanced technology intraocular lenses. PMID- 29572457 TI - Chitosan and cloxacillin combination improve antibiotic efficacy against different lifestyle of coagulase-negative Staphylococcus isolates from chronic bovine mastitis. AB - Bovine mastitis affects the health of dairy cows and the profitability of herds worldwide. Coagulase-negative staphylococci (CNS) are the most frequently isolated pathogens in bovine intramammary infection. Based on the wide range of antimicrobial, mucoadhesive and immunostimulant properties demonstrated by chitosan, we have evaluated therapy efficiency of chitosan incorporation to cloxacillin antibiotic as well as its effect against different bacterial lifestyles of seven CNS isolates from chronic intramammary infections. The therapeutic effects of combinations were evaluated on planktonic cultures, bacterial biofilms and intracellular growth in mammary epithelial cells. We found that biofilms and intracellular growth forms offered a strong protection against antibiotic therapy. On the other hand, we found that chitosan addition to cloxacillin efficiently reduced the antibiotic concentration necessary for bacterial killing in different lifestyle. Remarkably, the combined treatment was not only able to inhibit bacterial biofilm establishment and increase preformed biofilm eradication, but it also reduced intracellular bacterial viability while it increased IL-6 secretion by infected epithelial cells. These findings provide a new approach to prophylactic drying therapy that could help to improve conventional antimicrobial treatment against different forms of bacterial growth in an efficient, safer and greener manner reducing multiresistant bacteria generation and spread. PMID- 29572458 TI - Predictors of poor neonatal outcomes in prenatally diagnosed multicystic dysplastic kidney disease. AB - OBJECTIVE: Multicystic dysplastic kidney (MCDK) is one of the most common anomalies detected by prenatal ultrasound. Our objective was to identify factors associated with severe adverse neonatal outcomes of prenatally diagnosed MCDK STUDY DESIGN: A retrospective review of prenatally diagnosed MCDK (1 January 2009 to 30 December 2014) from a single academic center was conducted. The primary outcome was death or need for dialysis among live-born infants. Associations between prenatal characteristics and outcome were analyzed by Fisher's exact test and Mann-Whitney test. RESULTS: A total of 53 cases of prenatally suspected MCDK were included, of which 46 cases were live-born and confirmed postnatally (38 survivors, 8 non-survivors). Prenatally diagnosed extrarenal anomalies, bilateral MCDK, contralateral renal anomalies, and anhydramnios were significantly associated with death or need for dialysis (all p < 0.0001). CONCLUSIONS: Prenatally identified findings are associated with adverse neonatal outcome, and can guide counseling and management planning. In the absence of significant associated findings, prenatally diagnosed unilateral MCDK has a benign neonatal course. PMID- 29572459 TI - Untargeted metabolomics reveals a new mode of action of pretomanid (PA-824). AB - Pretomanid is a promising anti-tubercular drug currently at clinical phase III, but its mechanisms of action are currently unclear. This study aimed to: (i) reveal the metabolome of Mycobacterium smegmatis under pretomanid treatment; (ii) compare major sources of metabolite variation in bacteria treated with pretomanid treatment and other antibiotics; and (iii) to target metabolites responsible for the killing activity of pretomanid in mycobacteria. Untargeted high-resolution metabolite profiling was carried out using flow infusion electrospray ion high resolution mass spectrometry (FIE-HRMS) to identify and quantify metabolites. The identification of key metabolites was independently confirmed by gas chromatography time-of flight mass spectrometry (GC-tofMS) in comparison to standards. Pretomanid treatments generated a unique distinctive metabolite profile when compared to ampicillin, ethambutol, ethionamide, isoniazid, kanamycin, linezolid, rifampicin and streptomycin. Metabolites which differed significantly only with pretomanid treatment were identified and mapped on to bacterial metabolic pathways. This targeted the pentose phosphate pathway with significant accumulation seen with fructose-6-phosphate, ribose-5-phosphate and glyceraldehyde-3-phosphate. These effects were linked to the accumulation of a toxic metabolite methylglyoxal. This compound showed significant antimicrobial activity (MIC 0.65 mM) against M. smegmatis. PMID- 29572460 TI - Association of NF-E2 Related Factor 2 (Nrf2) and inflammatory cytokines in recent onset Type 2 Diabetes Mellitus. AB - We investigated the association of redox regulator Nuclear factor erythroid 2 related factor 2 (Nrf2) and inflammatory cytokines as well as clinical remission in patients with recent onset type 2 diabetes (DM). Blood was collected from 180 DM patients (105 males/75 females) and 150 control subjects (86 males/64 females). Blood glucose, HbA1c, lipid profile and Nrf2 levels were determined along with circulatory cytokines in study subjects. The data were adjusted with confounding factors such as age and sex using multiple logistic regression analysis. We found that Th1/Th2 and oxidative stress markers were significantly elevated, whereas Nrf2 and its downstream targets were decreased in peripheral blood mononuclear cells (PBMCs) of DM subjects when compared with control. The circulatory levels of Nrf2 showed a positive correlation with Th2 cytokines and negative correlation to Th1 cytokines. Further, the impaired insulin secretion in pancreatic beta-cells observed due to cytokine stress has been restored by activation of Nrf2 as assessed by glucose-stimulated insulin secretion (GSIS). This study identifies Nrf2 plays a central role in skewing Th1 and Th2 dominance in the progression of diabetes. PMID- 29572461 TI - Dnmt3a in the dorsal dentate gyrus is a key regulator of fear renewal. AB - Renewal of extinguished fear memory in an altered context is widely believed to be a major limiting issue for exposure therapy in treating various psychiatric diseases. Effective prevention of fear renewal will significantly improve the efficacy of exposure therapy. DNA methyltransferase (DNMTs) mediated epigenetic processes play critical roles in long term memory, but little is known about their functions in fear memory extinction or renewal. Here we investigated whether DNMTs regulate fear renewal after extinction. We found that elevated Dnmt3a level in the dorsal dentate gyrus (dDG) of hippocampus was associated with the absence of fear renewal in an altered context after extinction training. Overexpression and knockdown of Dnmt3a in the dDG regulated the occurrence of fear renewal in a bi-directional manner. In addition, Dnmt3a overexpression was associated with elevated expression of c-Fos in the dDG during extinction training. Furthermore, we found that renewal of remote fear memory can be prevented, and the absence of renewal was concurrent with an elevated Dnmt3a level. Our results indicate that Dnmt3a in the dDG is a key regulator of fear renewal after extinction, and Dnmt3a may play a critical role in controlling fear memory return and thus has therapeutic values. PMID- 29572462 TI - Regulation of IL-22BP in psoriasis. AB - IL-22 is a potent pro-inflammatory cytokine upregulated in psoriasis and in other inflammatory diseases. The function of IL-22 is regulated by the soluble scavenging receptor, IL-22 binding protein (IL-22BP or IL-22RA2). However, the role and regulation of IL-22BP itself in the pathogenesis of inflammatory disease remain unclear. We used the TLR7 agonist Imiquimod (IMQ) to induce a psoriasis like skin disease in mice and found a strong downregulation of IL-22BP in the affected skin as well as in the lymph nodes of animals treated with IMQ. We also analysed psoriatic skin of patients and compared this to skin of healthy donors. Interestingly, IL-22BP expression was similarly downregulated in skin biopsies of psoriasis patients compared to the skin of healthy donors. Since IL-22BP is expressed foremost in dendritic cells, we characterized its expression in monocyte-derived dendritic cells (MoDC) during maturation. In this way, we found Prostaglandin E2 (PGE2) to be a potent suppressor of IL-22BP expression in vitro. We conclude that regulation of IL-22BP by inflammatory mediators is an important step for the progression of inflammation in the skin and possibly also in other autoimmune diseases. PMID- 29572463 TI - Knowledge and self-reported practices of infection control among various occupational groups in a rural and an urban hospital in Vietnam. AB - Staff practice, driven by knowledge, plays a decisive role in hospital infection control. This study aimed to assess and compare knowledge and self-reported practices of infection control among various occupational groups in a rural and an urban hospital in Vietnam. Questionnaires consisting of items on knowledge and practices were collected from 339 hospital staff with varying occupations. For analysis, total knowledge or practice score ranged from 0-15. Mood's median test was performed to compare median scores. Post-hoc analysis of ordinal logistic regression models was applied to test differences in scores among occupational groups. The majority of hospital staff had good or adequate knowledge (median score: rural = 11.8; urban = 12), but the score range was wide (1.4-14.5). Self reported practices in the urban hospital were likely to be better than in the rural one (p = 0.003). Self-reported practices yet not completely satisfactory, indicating the need for continuing professional development in both settings. Overall, cleaners had lower scores than both physicians and nurses, highlighting the need for tailored education in this topic. Future infection control strategies within the hospitals might want to assess the difference between the staff's self-reported practice and their actual real practice. These findings can be of value in many other similar settings. PMID- 29572464 TI - Concurrent action of purifying selection and gene conversion results in extreme conservation of the major stress-inducible Hsp70 genes in mammals. AB - Several evolutionary mechanisms alter the fate of mutations and genes within populations based on their exhibited functional effects. To understand the underlying mechanisms involved in the evolution of the cellular stress response, a very conserved mechanism in the course of organismal evolution, we studied the patterns of natural genetic variation and functional consequences of polymorphisms of two stress-inducible Hsp70 genes. These genes, HSPA1A and HSPA1B, are major orchestrators of the cellular stress response and are associated with several human diseases. Our phylogenetic analyses revealed that the duplication of HSPA1A and HSPA1B originated in a lineage proceeding to placental mammals, and henceforth they remained in conserved synteny. Additionally, analyses of synonymous and non-synonymous changes suggest that purifying selection shaped the HSPA1 gene diversification, while gene conversion resulted in high sequence conservation within species. In the human HSPA1 cluster, the vast majority of mutations are synonymous and specific genic regions are devoid of mutations. Furthermore, functional characterization of several human polymorphisms revealed subtle differences in HSPA1A stability and intracellular localization. Collectively, the observable patterns of HSPA1A-1B variation describe an evolutionary pattern, in which purifying selection and gene conversion act simultaneously and conserve a major orchestrator of the cellular stress response. PMID- 29572466 TI - Adaptive nodes enrich nonlinear cooperative learning beyond traditional adaptation by links. AB - Physical models typically assume time-independent interactions, whereas neural networks and machine learning incorporate interactions that function as adjustable parameters. Here we demonstrate a new type of abundant cooperative nonlinear dynamics where learning is attributed solely to the nodes, instead of the network links which their number is significantly larger. The nodal, neuronal, fast adaptation follows its relative anisotropic (dendritic) input timings, as indicated experimentally, similarly to the slow learning mechanism currently attributed to the links, synapses. It represents a non-local learning rule, where effectively many incoming links to a node concurrently undergo the same adaptation. The network dynamics is now counterintuitively governed by the weak links, which previously were assumed to be insignificant. This cooperative nonlinear dynamic adaptation presents a self-controlled mechanism to prevent divergence or vanishing of the learning parameters, as opposed to learning by links, and also supports self-oscillations of the effective learning parameters. It hints on a hierarchical computational complexity of nodes, following their number of anisotropic inputs and opens new horizons for advanced deep learning algorithms and artificial intelligence based applications, as well as a new mechanism for enhanced and fast learning by neural networks.

They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety of nanoparticles of significant fundamental and applied interest. Here we present a combined experimental and computational study of the behaviour of nanodiamonds under irradiation by xenon ions. Unexpectedly, we observed a pronounced size effect on the radiation resistance of the nanodiamonds: particles larger than 8 nm behave similarly to macroscopic diamond (i.e. characterized by high radiation resistance) whereas smaller particles can be completely destroyed by a single impact from an ion in a defined energy range. This latter observation is explained by extreme heating of the nanodiamonds by the penetrating ion. The obtained results are not limited to nanodiamonds, making them of interest for several fields, putting constraints on processes for the controlled modification of nanodiamonds, on the survival of dust in astrophysical environments, and on the behaviour of actinides released from nuclear waste into the environment.

AB - Most interesting phenomena of condensed matter physics originate from interactions among different degrees of freedom, making it a very intriguing yet challenging question how certain ground states emerge from only a limited number of atoms in assembly. This is especially the case for strongly correlated electron systems with overwhelming complexity. The Verwey transition of Fe3O4 is a classic example of this category, of which the origin is still elusive 80 years after the first report. Here we report, for the first time, that the Verwey transition of Fe3O4 nanoparticles exhibits size-dependent thermal hysteresis in magnetization, 57Fe NMR, and XRD measurements. The hysteresis width passes a maximum of 11 K when the size is 120 nm while dropping to only 1 K for the bulk sample. This behavior is very similar to that of magnetic coercivity and the critical sizes of the hysteresis and the magnetic single domain are identical. We interpret it as a manifestation of charge ordering and spin ordering correlation in a single domain. This work paves a new way of undertaking researches in the vibrant field of strongly correlated electron physics combined with nanoscience. PMID- 29572468 TI - Impact of spatial organization on a novel auxotrophic interaction among soil microbes. AB - A key prerequisite to achieve a deeper understanding of microbial communities and to engineer synthetic ones is to identify the individual metabolic interactions among key species and how these interactions are affected by different environmental factors. Deciphering the physiological basis of species-species and species-environment interactions in spatially organized environments requires reductionist approaches using ecologically and functionally relevant species. To this end, we focus here on a defined system to study the metabolic interactions in a spatial context among the plant-beneficial endophytic fungus Serendipita indica, and the soil-dwelling model bacterium Bacillus subtilis. Focusing on the growth dynamics of S. indica under defined conditions, we identified an auxotrophy in this organism for thiamine, which is a key co-factor for essential reactions in the central carbon metabolism. We found that S. indica growth is restored in thiamine-free media, when co-cultured with B. subtilis. The success of this auxotrophic interaction, however, was dependent on the spatial and temporal organization of the system; the beneficial impact of B. subtilis was only visible when its inoculation was separated from that of S. indica either in time or space. These findings describe a key auxotrophic interaction in the soil among organisms that are shown to be important for plant ecosystem functioning, and point to the potential importance of spatial and temporal organization for the success of auxotrophic interactions. These points can be particularly important for engineering of minimal functional synthetic communities as plant seed treatments and for vertical farming under defined conditions. PMID- 29572469 TI - A new hybrid approach for MHC genotyping: high-throughput NGS and long read MinION nanopore sequencing, with application to the non-model vertebrate Alpine chamois (Rupicapra rupicapra). AB - The major histocompatibility complex (MHC) acts as an interface between the immune system and infectious diseases. Accurate characterization and genotyping of the extremely variable MHC loci are challenging especially without a reference sequence. We designed a combination of long-range PCR, Illumina short-reads, and Oxford Nanopore MinION long-reads approaches to capture the genetic variation of the MHC II DRB locus in an Italian population of the Alpine chamois (Rupicapra rupicapra). We utilized long-range PCR to generate a 9 Kb fragment of the DRB locus. Amplicons from six different individuals were fragmented, tagged, and simultaneously sequenced with Illumina MiSeq. One of these amplicons was sequenced with the MinION device, which produced long reads covering the entire amplified fragment. A pipeline that combines short and long reads resolved several short tandem repeats and homopolymers and produced a de novo reference, which was then used to map and genotype the short reads from all individuals. The assembled DRB locus showed a high level of polymorphism and the presence of a recombination breakpoint. Our results suggest that an amplicon-based NGS approach coupled with single-molecule MinION nanopore sequencing can efficiently achieve both the assembly and the genotyping of complex genomic regions in multiple individuals in the absence of a reference sequence. PMID- 29572470 TI - Transcriptomic signatures of NK cells suggest impaired responsiveness in HIV-1 infection and increased activity post-vaccination. AB - Natural killer (NK) cells limit viral replication by direct recognition of infected cells, antibody-dependent cellular cytotoxicity (ADCC), and releasing cytokines. Although growing evidence supports NK cell antiviral immunity in HIV-1 infection, further knowledge of their response is necessary. Here we show that NK cells responding to models of direct cell recognition, ADCC, and cytokine activation have unique transcriptional fingerprints. Compared with healthy volunteers, individuals with chronic HIV-1 infection have higher expression of genes commonly associated with activation, and lower expression of genes associated with direct cell recognition and cytokine stimulation in their NK cells. By contrast, NK cell transcriptional profiles of individuals receiving a modified vaccinia Ankara (MVA) vectored HIV-1 vaccine show upregulation of genes associated with direct cell recognition. These findings demonstrate that targeted transcriptional profiling provides a sensitive assessment of NK cell activity, which helps understand how NK cells respond to viral infections and vaccination. PMID- 29572471 TI - BAFF-neutralizing interaction of belimumab related to its therapeutic efficacy for treating systemic lupus erythematosus. AB - BAFF, a member of the TNF superfamily, has been recognized as a good target for autoimmune diseases. Belimumab, an anti-BAFF monoclonal antibody, was approved by the FDA for use in treating systemic lupus erythematosus. However, the molecular basis of BAFF neutralization by belimumab remains unclear. Here our crystal structure of the BAFF-belimumab Fab complex shows the precise epitope and the BAFF-neutralizing mechanism of belimumab, and demonstrates that the therapeutic activity of belimumab involves not only antagonizing the BAFF-receptor interaction, but also disrupting the formation of the more active BAFF 60-mer to favor the induction of the less active BAFF trimer through interaction with the flap region of BAFF. In addition, the belimumab HCDR3 loop mimics the DxL(V/L) motif of BAFF receptors, thereby binding to BAFF in a similar manner as endogenous BAFF receptors. Our data thus provides insights for the design of new drugs targeting BAFF for the treatment of autoimmune diseases. PMID- 29572472 TI - Diversity of innate immune cell subsets across spatial and temporal scales in an EAE mouse model. AB - In both multiple sclerosis and its model experimental autoimmune encephalomyelitis (EAE), the extent of resident microglia activation and infiltration of monocyte-derived cells to the CNS is positively correlated to tissue damage. To address the phenotype characterization of different cell subsets, their spatio-temporal distributions and contributions to disease development we induced EAE in Thy1-CFP//LysM-EGFP//CD11c-EYFP reporter mice. We combined high content flow cytometry, immunofluorescence and two-photon imaging in live mice and identified a stepwise program of inflammatory cells accumulation. First on day 10 after induction, EGFP+ neutrophils and monocytes invade the spinal cord parenchyma through the meninges rather than by extravasion. This event occurs just before axonal losses in the white matter. Once in the parenchyma, monocytes mature into EGFP+/EYFP+ monocyte-derived dendritic cells (moDCs) whose density is maximal on day 17 when the axonal degradation and clinical signs stabilize. Meanwhile, microglia is progressively activated in the grey matter and subsequently recruited to plaques to phagocyte axon debris. LysM-EGFP//CD11c-EYFP mice appear as a powerful tool to differentiate moDCs from macrophages and to study the dynamics of immune cell maturation and phenotypic evolution in EAE. PMID- 29572473 TI - Lactobacillus paracasei CNCM I-3689 reduces vancomycin-resistant Enterococcus persistence and promotes Bacteroidetes resilience in the gut following antibiotic challenge. AB - Enterococci, in particular vancomycin-resistant enterococci (VRE), are a leading cause of hospital-acquired infections. Promoting intestinal resistance against enterococci could reduce the risk of VRE infections. We investigated the effects of two Lactobacillus strains to prevent intestinal VRE. We used an intestinal colonisation mouse model based on an antibiotic-induced microbiota dysbiosis to mimic enterococci overgrowth and VRE persistence. Each Lactobacillus spp. was administered daily to mice starting one week before antibiotic treatment until two weeks after antibiotic and VRE inoculation. Of the two strains, Lactobacillus paracasei CNCM I-3689 decreased significantly VRE numbers in the feces demonstrating an improvement of the reduction of VRE. Longitudinal microbiota analysis showed that supplementation with L. paracasei CNCM I-3689 was associated with a better recovery of members of the phylum Bacteroidetes. Bile salt analysis and expression analysis of selected host genes revealed increased level of lithocholate and of ileal expression of camp (human LL-37) upon L. paracasei CNCM I-3689 supplementation. Although a direct effect of L. paracasei CNCM I-3689 on the VRE reduction was not ruled out, our data provide clues to possible anti-VRE mechanisms supporting an indirect anti-VRE effect through the gut microbiota. This work sustains non-antibiotic strategies against opportunistic enterococci after antibiotic-induced dysbiosis. PMID- 29572474 TI - Ecological control of nitrite in the upper ocean. AB - Microorganisms oxidize organic nitrogen to nitrate in a series of steps. Nitrite, an intermediate product, accumulates at the base of the sunlit layer in the subtropical ocean, forming a primary nitrite maximum, but can accumulate throughout the sunlit layer at higher latitudes. We model nitrifying chemoautotrophs in a marine ecosystem and demonstrate that microbial community interactions can explain the nitrite distributions. Our theoretical framework proposes that nitrite can accumulate to a higher concentration than ammonium because of differences in underlying redox chemistry and cell size between ammonia- and nitrite-oxidizing chemoautotrophs. Using ocean circulation models, we demonstrate that nitrifying microorganisms are excluded in the sunlit layer when phytoplankton are nitrogen-limited, but thrive at depth when phytoplankton become light-limited, resulting in nitrite accumulation there. However, nitrifying microorganisms may coexist in the sunlit layer when phytoplankton are iron- or light-limited (often in higher latitudes). These results improve understanding of the controls on nitrification, and provide a framework for representing chemoautotrophs and their biogeochemical effects in ocean models. PMID- 29572475 TI - Structure and evolution of the Fam20 kinases. AB - The Fam20 proteins are novel kinases that phosphorylate secreted proteins and proteoglycans. Fam20C phosphorylates hundreds of secreted proteins and is activated by the pseudokinase Fam20A. Fam20B phosphorylates a xylose residue to regulate proteoglycan synthesis. Despite these wide-ranging and important functions, the molecular and structural basis for the regulation and substrate specificity of these kinases are unknown. Here we report molecular characterizations of all three Fam20 kinases, and show that Fam20C is activated by the formation of an evolutionarily conserved homodimer or heterodimer with Fam20A. Fam20B has a unique active site for recognizing Galbeta1-4Xylbeta1, the initiator disaccharide within the tetrasaccharide linker region of proteoglycans. We further show that in animals the monomeric Fam20B preceded the appearance of the dimeric Fam20C, and the dimerization trait of Fam20C emerged concomitantly with a change in substrate specificity. Our results provide comprehensive structural, biochemical, and evolutionary insights into the function of the Fam20 kinases. PMID- 29572476 TI - Linear and inverted U-shaped dose-response functions describe estrogen effects on hippocampal activity in young women. AB - In animals, 17-beta-estradiol (E2) enhances hippocampal plasticity in a dose dependent, monotonically increasing manner, but this relationship can also exhibit an inverted U-shaped function. To investigate E2's dose-response function in the human hippocampus, we pharmacologically increased E2 levels in 125 naturally cycling women (who were in their low-hormone menstruation phase) to physiological (equivalent to menstrual cycle peak) and supraphysiological (equivalent to levels during early pregnancy) concentrations in a placebo controlled design. Twenty-four hours after first E2 intake, we measured brain activity during encoding of neutral and negative pictures and then tested recognition memory 24 h after encoding. Here we report that E2 exhibits both a monotonically increasing relationship with hippocampal activity as well as an inverted U-shaped relationship, depending on the hippocampal region. Hippocampal activity exhibiting a U-shaped relationship inflects at supraphysiological E2 levels, suggesting that while E2 within physiological ranges stimulates hippocampal activity, supraphysiological ranges show opposite effects. PMID- 29572477 TI - Mechanism of action of the third generation benzopyrans and evaluation of their broad anti-cancer activity in vitro and in vivo. AB - Successive rounds of chemical modification in three generations of benzopyran molecules have shown to select for different mechanisms of actions and progressive increases in anti-cancer activity. In this study, we investigated the mechanism of action of the third-generation benzopyran compounds, TRX-E-002-1 and TRX-E-009-1. High-content screening of a panel of 240 cancer cell lines treated with TRX-E-009-1 demonstrated it has broad anti-cancer potential. Within this screen, melanoma cell lines showed a range of sensitivities and subsequently a second independent panel of 21 melanoma 3D spheroid lines were assessed for their responses to both TRX-E-002-1 and TRX-E-009-1 compounds. Time-lapse microscopy illustrated both of these compounds caused mitotic delays in treated cells, resulting in either mitotic slippage or apoptosis. This finding along with immunostaining, in vitro polymerization assays, and animal experiments in both athymic and immunocompetent mice, demonstrates that these third-generation benzopyran compounds are potent tubulin polymerization inhibitors in vitro and in vivo, and this is the molecular basis of their anti-cancer activity in melanoma. These findings indicate these BP compounds may offer a novel anti-microtubule strategy for cancer intervention and provides the basis for further investigation into biomarkers of clinical sensitivity. PMID- 29572478 TI - Increased Levels of Cardiac Troponin I in Subjects with Extremely Low B-type Natriuretic Peptide Levels. AB - Because of the lack of studies focused on the biological implications of extremely low B-type natriuretic peptide (BNP) levels, we investigated whether extremely low BNP levels could be harmful to the cardiovascular system due to compromised cardio-protection. By using cardiac troponin I (cTnI) as an indicator of cardiovascular disorder, we assessed whether cTnI was inversely associated with BNP in populations with low BNP levels. A total of 2,001 apparently healthy subjects older than 38 years were included in this study. We defined subgroups from this population by limiting the maximum BNP level with cut-off values ranging from 1 through 20 pg/mL and performed covariance structure analyses by comparing log(BNP) with log(cTnI) in each subgroup. The beta values between log(BNP) and log(cTnI) sharply decreased as the BNP cut-off was reduced from 20 pg/mL (beta = 0.04) to 1 pg/mL (beta = -0.29) and became significant when the BNP cut-off levels were lower than 4 pg/mL (p < 0.005). In subgroups with BNP levels lower than 4 pg/mL, elevation in cTnI level was inversely associated with BNP (p < 0.005), which suggests that insufficient BNP may play a pathogenic role in the occurrence of cardiovascular abnormalities. PMID- 29572479 TI - Cut Based Method for Comparing Complex Networks. AB - Revealing the underlying similarity of various complex networks has become both a popular and interdisciplinary topic, with a plethora of relevant application domains. The essence of the similarity here is that network features of the same network type are highly similar, while the features of different kinds of networks present low similarity. In this paper, we introduce and explore a new method for comparing various complex networks based on the cut distance. We show correspondence between the cut distance and the similarity of two networks. This correspondence allows us to consider a broad range of complex networks and explicitly compare various networks with high accuracy. Various machine learning technologies such as genetic algorithms, nearest neighbor classification, and model selection are employed during the comparison process. Our cut method is shown to be suited for comparisons of undirected networks and directed networks, as well as weighted networks. In the model selection process, the results demonstrate that our approach outperforms other state-of-the-art methods with respect to accuracy. PMID- 29572480 TI - Brain activations associated with fearful experience show common and distinct patterns between younger and older adults in the hippocampus and the amygdala. AB - Revisiting threat-related scenes elicits fear and activates a brain network related to cognitive-affective processing. Prior experience may contribute to the present fearful experience. We aimed to investigate (a) patterns of brain activation associated with individual differences in past fearful experiences (pFear) and the present fear elicited by watching videos (eFear) and (b) age related differences in the activation patterns. Forty healthy adults, including 20 younger adults (YA) and 20 older adults (OA), underwent functional magnetic resonance imaging while watching videos containing high- and low-threat scenes of medical treatment. Both age subgroups showed positive correlations between pFear and bilateral hippocampal activation. Only YA showed threat-related activation in the bilateral anterior insula and activation positively correlated with pFear in the bilateral S1 and the amygdala. The evidence suggests that the hippocampus, amygdala and S1 may play key roles in bridging past fearful experiences and the present fear elicited by revisiting visual scenes and that the interaction between memory and emotional processing may be age dependent. PMID- 29572481 TI - Tibial Osteotomy as a Mechanical Model of Primary Osteoarthritis in Rats. AB - This study has presented the first purely biomechanical surgical model of osteoarthritis (OA) in rats, which could be more representative of the human primary disease than intra-articular techniques published previously. A surgical tibial osteotomy (TO) was used to induce degenerative cartilage changes in the medial knee of Sprague-Dawley rats. The presence of osteoarthritic changes in the medial knee compartment of the operated animals was evaluated histologically and through analysis of serum carboxy-terminal telepeptides of type II collagen (CTX II). In-vivo biomechanical analyses were carried out using a musculoskeletal model of the rat hindlimb to evaluate the loading conditions in the knee pre and post-surgically. Qualitative and quantitative medial cartilage degeneration consistent with OA was found in the knees of the operated animals alongside elevated CTX-II levels and increased tibial compressive loading. The potential avoidance of joint inflammation post-surgically, the maintenance of internal joint biomechanics and the ability to quantify the alterations in joint loading should make this model of OA a better candidate for modeling primary forms of the disease in humans. PMID- 29572482 TI - Bacteriophages are more virulent to bacteria with human cells than they are in bacterial culture; insights from HT-29 cells. AB - Bacteriophage therapeutic development will clearly benefit from understanding the fundamental dynamics of in vivo phage-bacteria interactions. Such information can inform animal and human trials, and much can be ascertained from human cell-line work. We have developed a human cell-based system using Clostridium difficile, a pernicious hospital pathogen with limited treatment options, and the phage phiCDHS1 that effectively kills this bacterium in liquid culture. The human colon tumorigenic cell line HT-29 was used because it simulates the colon environment where C. difficile infection occurs. Studies on the dynamics of phage-bacteria interactions revealed novel facets of phage biology, showing that phage can reduce C. difficile numbers more effectively in the presence of HT-29 cells than in vitro. Both planktonic and adhered Clostridial cell numbers were successfully reduced. We hypothesise and demonstrate that this observation is due to strong phage adsorption to the HT-29 cells, which likely promotes phage-bacteria interactions. The data also showed that the phage phiCDHS1 was not toxic to HT-29 cells, and phage-mediated bacterial lysis did not cause toxin release and cytotoxic effects. The use of human cell lines to understand phage-bacterial dynamics offers valuable insights into phage biology in vivo, and can provide informative data for human trials. PMID- 29572484 TI - Phthalate metabolite exposures among immigrants living in the United States: findings from NHANES, 1999-2014. AB - Phthalates exposure has been linked to multiple health risks, and US immigrants may have different exposures to phthalates due to lifestyle differences. Urinary concentrations of eight phthalate metabolites (mono-ethyl phthalate [MEP], mono-n butyl phthalate [MnBP], mono-isobutyl phthalate [MiBP], mono-(3-carboxypropyl) phthalate [MCPP], mono-benzyl phthalate [MBzP], mono-2-ethylhexyl phthalate [MEHP], mono-(2-ethyl-5-hydroxyhexyl) phthalate [MEHHP], mono-(2-ethyl-5 oxohexyl) phthalate [MEOHP]) were measured in 10318 US-born and 3511 foreign-born individuals from NHANES 1999-2014. Using multivariate adjusted linear regression, we assessed whether phthalate metabolite levels differed by nativity in the whole population, within racial/ethnic groups, and by years in the US. We also tested whether immigrant demographics predicted phthalate metabolite levels. In fully adjusted models, MEP, MnBP, and MiBP were significantly higher, and MBzP significantly lower, among immigrants than US-born participants. Among immigrants, MnBP and MiBP significantly declined with longer time in the US (Ptrend = 0.029 and Ptrend = 0.039, respectively), while MCPP and MBzP significantly rose (Ptrend = 0.019 and Ptrend = 0.043, respectively). Results within each racial/ethnic group were consistent with the whole population. Among immigrants, women had significantly higher metabolite levels than men (all p < 0.01), and MEP, MnBP, and MCPP differed by race/ethnicity. Due to higher phthalate exposures, immigrants may be especially vulnerable to phthalate associated health problems. PMID- 29572483 TI - The orphan GPR50 receptor promotes constitutive TGFbeta receptor signaling and protects against cancer development. AB - Transforming growth factor-beta (TGFbeta) signaling is initiated by the type I, II TGFbeta receptor (TbetaRI/TbetaRII) complex. Here we report the formation of an alternative complex between TbetaRI and the orphan GPR50, belonging to the G protein-coupled receptor super-family. The interaction of GPR50 with TbetaRI induces spontaneous TbetaRI-dependent Smad and non-Smad signaling by stabilizing the active TbetaRI conformation and competing for the binding of the negative regulator FKBP12 to TbetaRI. GPR50 overexpression in MDA-MB-231 cells mimics the anti-proliferative effect of TbetaRI and decreases tumor growth in a xenograft mouse model. Inversely, targeted deletion of GPR50 in the MMTV/Neu spontaneous mammary cancer model shows decreased survival after tumor onset and increased tumor growth. Low GPR50 expression is associated with poor survival prognosis in human breast cancer irrespective of the breast cancer subtype. This describes a previously unappreciated spontaneous TGFbeta-independent activation mode of TbetaRI and identifies GPR50 as a TbetaRI co-receptor with potential impact on cancer development. PMID- 29572485 TI - Degradation of blue-phosphorescent organic light-emitting devices involves exciton-induced generation of polaron pair within emitting layers. AB - Degradation of organic materials is responsible for the short operation lifetimes of organic light-emitting devices, but the mechanism by which such degradation is initiated has yet to be fully established. Here we report a new mechanism for degradation of emitting layers in blue-phosphorescent devices. We investigate binary mixtures of a wide bandgap host and a series of novel Ir(III) complex dopants having N-heterocyclocarbenic ligands. Our mechanistic study reveals the charge-neutral generation of polaron pairs (radical ion pairs) by electron transfer from the dopant to host excitons. Annihilation of the radical ion pair occurs by charge recombination, with such annihilation competing with bond scission. Device lifetime correlates linearly with the rate constant for the annihilation of the radical ion pair. Our findings demonstrate the importance of controlling exciton-induced electron transfer, and provide novel strategies to design materials for long-lifetime blue electrophosphorescence devices.

PMID- 29572489 TI - Iron regulatory protein deficiency compromises mitochondrial function in murine embryonic fibroblasts. AB - Iron is essential for growth and proliferation of mammalian cells. The maintenance of cellular iron homeostasis is regulated by iron regulatory proteins (IRPs) through binding to the cognate iron-responsive elements in target mRNAs and thereby regulating the expression of target genes. Irp1 or Irp2-null mutation is known to reduce the cellular iron level by decreasing transferrin receptor 1 and increasing ferritin. Here, we report that Irp1 or Irp2-null mutation also causes downregulation of frataxin and IscU, two of the core components in the iron-sulfur cluster biogenesis machinery. Interestingly, while the activities of some of iron-sulfur cluster-containing enzymes including mitochondrial aconitase and cytosolic xanthine oxidase were not affected by the mutations, the activities of respiratory chain complexes were drastically diminished resulting in mitochondrial dysfunction. Overexpression of human ISCU and frataxin in Irp1 or Irp2-null cells was able to rescue the defects in iron-sulfur cluster biogenesis and mitochondrial quality. Our results strongly suggest that iron regulatory proteins regulate the part of iron sulfur cluster biogenesis tailored specifically for mitochondrial electron transport chain complexes. PMID- 29572490 TI - Mice lacking the mitochondrial exonuclease MGME1 accumulate mtDNA deletions without developing progeria. AB - Replication of mammalian mitochondrial DNA (mtDNA) is an essential process that requires high fidelity and control at multiple levels to ensure proper mitochondrial function. Mutations in the mitochondrial genome maintenance exonuclease 1 (MGME1) gene were recently reported in mitochondrial disease patients. Here, to study disease pathophysiology, we generated Mgme1 knockout mice and report that homozygous knockouts develop depletion and multiple deletions of mtDNA. The mtDNA replication stalling phenotypes vary dramatically in different tissues of Mgme1 knockout mice. Mice with MGME1 deficiency accumulate a long linear subgenomic mtDNA species, similar to the one found in mtDNA mutator mice, but do not develop progeria. This finding resolves a long standing debate by showing that point mutations of mtDNA are the main cause of progeria in mtDNA mutator mice. We also propose a role for MGME1 in the regulation of replication and transcription termination at the end of the control region of mtDNA.

AB - Understanding the role of different sources that contribute to the aerosol extinction coefficient is an important aspect toward analyzing climate change and regional air quality. In Beijing specifically, the region has suffered severe air quality deterioration over the past three decades, but the magnitude of extraneous contributions to aerosol variation has remained uncertain. Therefore, we estimated trends of contributions to aerosol optical depth (AOD) for Beijing from 1980 to 2014 and built a seasonal regression model to decouple the extraneous contribution from the total emitted using ground-based aerosol and meteorological measurements, extended to the emissions of man-made and natural contribution. The variation of AOD over Beijing was significantly affected by the anthropogenic aerosol emissions, which experienced slight augmentation by 15.3% from 1980 to 2000, rapid inflation by 36.9% from 2000 to 2006, and a gradual decrease by 10.0% from 2006 to 2014. The extraneous contribution from wind and its associated languishing patterns explain the historical increase of regional AOD, which experienced about a 10% enhancement over the three stages. Other meteorological contributions show no significant trends over 35 years, except for the temperature inversion, which despite the weakened hygroscopic growth after 2006, still experiences a significant enhancement. PMID- 29572493 TI - Evidence for Layered Quantized Transport in Dirac Semimetal ZrTe5. AB - ZrTe5 is an important semiconductor thermoelectric material and a candidate topological insulator. Here we report the observation of Shubnikov-de Hass (SdH) oscillations accompanied by quantized Hall resistance in bulk ZrTe5 crystal, with a mobility of 41,000 cm2V-1s-1. We have found that the quantum oscillations does not originate from the surface states, but from the bulk states. Each single layer ZrTe5 acted like an independent 2D electron system in the quantum Hall regime having the same carrier density and mobilities, while the bulk of the sample exhibits a multilayered quantum Hall effect. PMID- 29572492 TI - Radiomic MRI signature reveals three distinct subtypes of glioblastoma with different clinical and molecular characteristics, offering prognostic value beyond IDH1. AB - The remarkable heterogeneity of glioblastoma, across patients and over time, is one of the main challenges in precision diagnostics and treatment planning. Non invasive in vivo characterization of this heterogeneity using imaging could assist in understanding disease subtypes, as well as in risk-stratification and treatment planning of glioblastoma. The current study leveraged advanced imaging analytics and radiomic approaches applied to multi-parametric MRI of de novo glioblastoma patients (n = 208 discovery, n = 53 replication), and discovered three distinct and reproducible imaging subtypes of glioblastoma, with differential clinical outcome and underlying molecular characteristics, including isocitrate dehydrogenase-1 (IDH1), O6-methylguanine-DNA methyltransferase, epidermal growth factor receptor variant III (EGFRvIII), and transcriptomic subtype composition. The subtypes provided risk-stratification substantially beyond that provided by WHO classifications. Within IDH1-wildtype tumors, our subtypes revealed different survival (p < 0.001), thereby highlighting the synergistic consideration of molecular and imaging measures for prognostication. Moreover, the imaging characteristics suggest that subtype-specific treatment of peritumoral infiltrated brain tissue might be more effective than current uniform standard-of-care. Finally, our analysis found subtype-specific radiogenomic signatures of EGFRvIII-mutated tumors. The identified subtypes and their clinical and molecular correlates provide an in vivo portrait of phenotypic heterogeneity in glioblastoma, which points to the need for precision diagnostics and personalized treatment.

AB - In this paper, a mechanically reconfigurable circular array with single-arm spiral antennas (SASAs) is designed, fabricated, and experimentally demonstrated to generate broadband circularly polarized orbital angular momentum (OAM) vortex waves in radio frequency domain. With the symmetrical and broadband properties of single-arm spiral antennas, the vortex waves with different OAM modes can be mechanically reconfigurable generated in a wide band from 3.4 GHz to 4.7 GHz. The prototype of the circular array is proposed, conducted, and fabricated to validate the theoretical analysis. The simulated and experimental results verify that different OAM modes can be effectively generated by rotating the spiral arms of single-arm spiral antennas with corresponding degrees, which greatly simplify the feeding network. The proposed method paves a reconfigurable way to generate multiple OAM vortex waves with spin angular momentum (SAM) in radio and microwave satellite communication applications.

The glucose reduced and food grade starch stabilized particles remained colloidally stable with less than a 4% change in the surface plasmon resonance band at 425-430 nm at t > 300 days. TEM determined the size of AgNPs, while TEM-EDS and XRD verified elemental composition. The conversion was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and thermal gravimetric analysis (TGA). Additionally, the required silver to starch input mass ratio, 1.0:1.3, to produce colloidally stabilized AgNPs is significantly reduced compared to previous studies. The antibacterial activity of freshly prepared AgNPs and AgNPs aged >300 days was demonstrated against E. coli as determined by agar diffusion assays. This result, corroborated by spectrophotometric and TEM measurements, indicates long-term colloidal stability of the product. Thus, this study sustainably produced antibacterial AgNPs from minimal inputs. In the broader context, the current work has quantified a sustainable platform technology to produce sphere-like inorganic nanoparticles with antimicrobial properties. PMID- 29572496 TI - Optical Detection of Degraded Therapeutic Proteins. AB - The quality of therapeutic proteins such as hormones, subunit and conjugate vaccines, and antibodies is critical to the safety and efficacy of modern medicine. Identifying malformed proteins at the point-of-care can prevent adverse immune reactions in patients; this is of special concern when there is an insecure supply chain resulting in the delivery of degraded, or even counterfeit, drug product. Identification of degraded protein, for example human growth hormone, is demonstrated by applying automated anomaly detection algorithms. Detection of the degraded protein differs from previous applications of machine learning and classification to spectral analysis: only example spectra of genuine, high-quality drug products are used to construct the classifier. The algorithm is tested on Raman spectra acquired on protein dilutions typical of formulated drug product and at sample volumes of 25 uL, below the typical overfill (waste) volumes present in vials of injectable drug product. The algorithm is demonstrated to correctly classify anomalous recombinant human growth hormone (rhGH) with 92% sensitivity and 98% specificity even when the algorithm has only previously encountered high-quality drug product.

AB - The platypus (Ornithorhynchus anatinus) is an evolutionarily distinct mammal, endemic to Australian freshwaters. Many aspects of its ecology and life-history, including detailed understanding of movements, are poorly known, hampered by its cryptic and mainly nocturnal habits and small numbers. We effectively trialled intraperitoneal implanted acoustic transmitters in nine platypuses in the Severn River (NSW), Australia, as a potential approach for studying movements in this challenging species. We tracked platypus movements over six months, at fine and broad spatial scales, using an array of acoustic sensors. Over six months (March August 2016), four of five adult platypuses (two females?three males) maintained localized movements (average monthly maximums 0.37 km +/- 0.03 sd), while one adult, one sub-adult, and one juvenile (males) moved further: average monthly maxima 1.2 km +/- 2.0 sd, 0.9 km +/- 0.6 sd, 4.5 km +/- 5.9 sd, respectively. The longest recorded movement was by a male adult, covering 11.1 km in three days and travelling a maximum distance of about 13 km between records. Only one implanted animal was not detected immediately after release, indicative of transmission failure rather than an adverse event. High cumulative daily movements (daily 1.9 km +/- 0.8 sd) indicated high metabolic requirements, with implications for previous estimates of platypus abundances and carrying capacities, essential for effective conservation. This novel approach offers new avenues to investigate relating to mating, nesting, and intraspecific competition behaviours and their temporal and spatial variation.

PMID- 29572498 TI - A single high-fat meal provokes pathological erythrocyte remodeling and increases myeloperoxidase levels: implications for acute coronary syndrome. AB - High-fat meal (HFM) consumption can produce acute lipemia and trigger myocardial infarction in patients with atherosclerosis, but the mechanisms are poorly understood. Erythrocytes (red blood cells, RBCs) intimately interact with inflammatory cells and blood vessels and play a complex role in regulating vascular function. Chronic high-fat feeding in mice induces pathological RBC remodeling, suggesting a novel link between HFM, RBCs, and vascular dysfunction. However, whether acute HFM can induce RBC remodeling in humans is unknown. Ten healthy individuals were subjected to biochemical testing and assessment of endothelial-dependent flow-mediated dilation (FMD) before and after a single HFM or iso-caloric meal (ICM). Following the HFM, triglyceride, cholesterol, and free fatty acid levels were all significantly increased, in conjunction with impaired post-prandial FMD. Additionally, peripheral blood smears demonstrated microcytes, remodeled RBCs, and fatty monocytes. Increased intracellular ROS and nitration of protein band 3 was detected in RBCs following the HFM. The HFM elevated plasma and RBC-bound myeloperoxidase (MPO), which was associated with impaired FMD and oxidation of HDL. Monocytic cells exposed to lipid in vitro released MPO, while porcine coronary arteries exposed to fatty acids ex vivo took up MPO. We demonstrate in humans that a single HFM induces pathological RBC remodeling and concurrently elevates MPO, which can potentially enter the blood vessel wall to trigger oxidative stress and destabilize vulnerable plaques. These novel findings may have implications for the short-term risk of HFM consumption and alimentary lipemia in patients with atherosclerosis. PMID- 29572500 TI - Basophil-lineage commitment in acute promyelocytic leukemia predicts for severe bleeding after starting therapy. AB - Severe hemorrhagic events occur in a significant fraction of acute promyelocytic leukemia patients, either at presentation and/or early after starting therapy, leading to treatment failure and early deaths. However, identification of independent predictors for high-risk of severe bleeding at diagnosis, remains a challenge. Here, we investigated the immunophenotype of bone marrow leukemic cells from 109 newly diagnosed acute promyelocytic leukemia patients, particularly focusing on the identification of basophil-related features, and their potential association with severe bleeding episodes and patient overall survival.From all phenotypes investigated on leukemic cells, expression of the CD203c and/or CD22 basophil-associated markers showed the strongest association with the occurrence and severity of bleeding (p <= 0.007); moreover, aberrant expression of CD7, coexpression of CD34+/CD7+ and lack of CD71 was also more frequently found among patients with (mild and severe) bleeding at baseline and/or after starting treatment (p <= 0.009). Multivariate analysis showed that CD203c expression (hazard ratio: 26.4; p = 0.003) and older age (hazard ratio: 5.4; p = 0.03) were the best independent predictors for cumulative incidence of severe bleeding after starting therapy. In addition, CD203c expression on leukemic cells (hazard ratio: 4.4; p = 0.01), low fibrinogen levels (hazard ratio: 8.8; p = 0.001), older age (hazard ratio: 9.0; p = 0.002), and high leukocyte count (hazard ratio: 5.6; p = 0.02) were the most informative independent predictors for overall survival.In summary, our results show that the presence of basophil-associated phenotypic characteristics on leukemic cells from acute promyelocytic leukemia patients at diagnosis is a powerful independent predictor for severe bleeding and overall survival, which might contribute in the future to (early) risk-adapted therapy decisions. PMID- 29572501 TI - Array-based DNA-methylation profiling in sarcomas with small blue round cell histology provides valuable diagnostic information. AB - Undifferentiated solid tumors with small blue round cell histology and expression of CD99 mostly resemble Ewing sarcoma. However, they also may include other tumors such as mesenchymal chondrosarcoma, synovial sarcoma, or small cell osteosarcoma. Definitive classification usually requires detection of entity specific mutations. While this approach identifies the majority of Ewing sarcomas, a subset of lesions remains unclassified and, therefore, has been termed "Ewing-like sarcomas" or small blue round cell tumors not otherwise specified. We developed an approach for further characterization of small blue round cell tumors not otherwise specified using an array-based DNA-methylation profiling approach. Data were analyzed by unsupervised clustering and t distributed stochastic neighbor embedding analysis and compared with a reference methylation data set of 460 well-characterized prototypical sarcomas encompassing 18 subtypes. Verification was performed by additional FISH analyses, RNA sequencing from formalin-fixed paraffin-embedded material or immunohistochemical marker analyses. In a cohort of more than 1,000 tumors assumed to represent Ewing sarcomas, 30 failed to exhibit the typical EWS translocation. These tumors were subjected to methylation profiling and could be assigned to Ewing sarcoma in 14 (47%), to small blue round cell tumors with CIC alteration in 6 (20%), to small blue round cell tumors with BCOR alteration in 4 (13%), to synovial sarcoma and to malignant rhabdoid tumor in 2 cases each. One single case each was allotted to mesenchymal chondrosarcoma and adamantinoma. 12/14 tumors classified as Ewing sarcoma could be verified by demonstrating either a canonical EWS translocation evading initial testing, by identifying rare breakpoints or fusion partners. The methylation-based assignment of the remaining small blue round cell tumors not otherwise specified also could be verified by entity-specific molecular alterations in 13/16 cases. In conclusion, array-based DNA-methylation analysis of undifferentiated tumors with small blue round cell histology is a powerful tool for precisely classifying this diagnostically challenging tumor group. PMID- 29572502 TI - Interpretation of biological experiments changes with evolution of the Gene Ontology and its annotations. AB - Gene Ontology (GO) enrichment analysis is ubiquitously used for interpreting high throughput molecular data and generating hypotheses about underlying biological phenomena of experiments. However, the two building blocks of this analysis - the ontology and the annotations - evolve rapidly. We used gene signatures derived from 104 disease analyses to systematically evaluate how enrichment analysis results were affected by evolution of the GO over a decade. We found low consistency between enrichment analyses results obtained with early and more recent GO versions. Furthermore, there continues to be a strong annotation bias in the GO annotations where 58% of the annotations are for 16% of the human genes. Our analysis suggests that GO evolution may have affected the interpretation and possibly reproducibility of experiments over time. Hence, researchers must exercise caution when interpreting GO enrichment analyses and should reexamine previous analyses with the most recent GO version. PMID- 29572504 TI - Timing of the Saalian- and Elsterian glacial cycles and the implications for Middle - Pleistocene hominin presence in central Europe. AB - By establishing a luminescence-based chronology for fluvial deposits preserved between the Elsterian- and Saalian tills in central Germany, we obtained information on the timing of both the Middle Pleistocene glacial cycles and early human appearance in central Europe. The luminescence ages illustrate different climatic driven fluvial aggradation periods during the Saalian glacial cycle spanning from 400-150 ka. The ages of sediments directly overlying the Elsterian till are approximately 400 ka and prove that the first extensive Fennoscandian ice sheet extension during the Quaternary correlates with MIS 12 and not with MIS 10. Furthermore, the 400 ka old fluvial units contain Lower Paleolithic stone artefacts that document the first human appearance in the region. In addition, we demonstrate that early MIS 8 is a potential date for the onset of the Middle Paleolithic in central Germany, as Middle Paleolithic stone artefacts are correlated with fluvial units deposited between 300 ka and 200 ka. However, the bulk of Middle Paleolithic sites date to MIS 7 in the region. The fluvial units preserved directly under the till of the southernmost Saalian ice yield an age of about 150 ka, and enable a correlation of the Drenthe stage to late MIS 6. PMID- 29572503 TI - A genomics approach reveals insights into the importance of gene losses for mammalian adaptations. AB - Identifying the genomic changes that underlie phenotypic adaptations is a key challenge in evolutionary biology and genomics. Loss of protein-coding genes is one type of genomic change with the potential to affect phenotypic evolution. Here, we develop a genomics approach to accurately detect gene losses and investigate their importance for adaptive evolution in mammals. We discover a number of gene losses that likely contributed to morphological, physiological, and metabolic adaptations in aquatic and flying mammals. These gene losses shed light on possible molecular and cellular mechanisms that underlie these adaptive phenotypes. In addition, we show that gene loss events that occur as a consequence of relaxed selection following adaptation provide novel insights into species' biology. Our results suggest that gene loss is an evolutionary mechanism for adaptation that may be more widespread than previously anticipated. Hence, investigating gene losses has great potential to reveal the genomic basis underlying macroevolutionary changes.

PMID- 29572506 TI - Health-related quality of life in lower-risk MDS patients compared with age- and sex-matched reference populations: a European LeukemiaNet study. AB - In myelodysplastic syndromes (MDS), health-related quality of life (HRQoL) represents a relevant patient-reported outcome, which is essential in individualized therapy planning. Prospective data on HRQoL in lower-risk MDS remain rare. We assessed HRQOL by EQ-5D questionnaire at initial diagnosis in 1690 consecutive IPSS-Low/Int-1 MDS patients from the European LeukemiaNet Registry. Impairments were compared with age- and sex-matched EuroQol Group norms. A significant proportion of MDS patients reported moderate/severe problems in the dimensions pain/discomfort (49.5%), mobility (41.0%), anxiety/depression (37.9%), and usual activities (36.1%). Limitations in mobility, self-care, usual activities, pain/discomfort, and EQ-VAS were significantly more frequent in the old, in females, and in those with high co-morbidity burden, low haemoglobin levels, or red blood cells transfusion need (p < 0.001). In comparison to age- and sex-matched peers, the proportion of problems in usual activities and anxiety/depression was significantly higher in MDS patients (p < 0.001). MDS related restrictions in the dimension mobility were most prominent in males, and in older people (p < 0.001); in anxiety/depression in females and in younger people (p < 0.001); and in EQ-VAS in women and in persons older than 75 years (p < 0.05). Patients newly diagnosed with IPSS lower-risk MDS experience a pronounced reduction in HRQoL and a clustering of restrictions in distinct dimensions of HRQoL as compared with reference populations.

AB - Oncogenic fusions are major drivers in leukemogenesis and may serve as potent targets for treatment. DUX4/IGHs have been shown to trigger the abnormal expression of ERGalt through binding to DUX4-Responsive-Element (DRE), which leads to B-cell differentiation arrest and a full-fledged B-ALL. Here, we determined the crystal structures of Apo- and DNADRE-bound DUX4HD2 and revealed a clamp-like transactivation mechanism via the double homeobox domain. Biophysical characterization showed that mutations in the interacting interfaces significantly impaired the DNA binding affinity of DUX4 homeobox. These mutations, when introduced into DUX4/IGH, abrogated its transactivation activity in Reh cells. More importantly, the structure-based mutants significantly impaired the inhibitory effects of DUX4/IGH upon B-cell differentiation in mouse progenitor cells. All these results help to define a key DUX4/IGH-DRE recognition/step in B-ALL. PMID- 29572509 TI - In-vivo biomagnetic characterisation of the American cockroach. AB - We present a quantitative method, utilising a highly sensitive quantum sensor, that extends applicability of magnetorelaxometry to biological samples at physiological temperature. The observed magnetic fields allow for non-invasive determination of physical properties of magnetic materials and their surrounding environment inside the specimen. The method is applied to American cockroaches and reveals magnetic deposits with strikingly different behaviour in alive and dead insects. We discuss consequences of this finding to cockroach magneto reception. To our knowledge, this work represents the first characterisation of the magnetisation dynamics in live insects and helps to connect results from behavioural experiments on insects in magnetic fields with characterisation of magnetic materials in their corpses. PMID- 29572510 TI - Same habitat types but different use: evidence of context-dependent habitat selection in roe deer across populations. AB - With the surge of GPS-technology, many studies uncovered space use of mobile animals and shed light on the underlying behavioral mechanisms of habitat selection. Habitat selection and variation in either occurrence or strength of functional responses (i.e. how selection changes with availability) have given new insight into such mechanisms within populations in different ecosystems. However, linking variation in habitat selection to site-specific conditions in different populations facing contrasting environmental conditions but the same habitat type has not yet been investigated. We aimed to fill this knowledge gap by comparing within-home range habitat selection across 61 female roe deer (Capreolus capreolus) during the most critical life history stage in three study areas showing the same habitat types but with different environmental conditions. Female roe deer markedly differed in habitat selection within their home range, both within and among populations. Females facing poor environmental conditions clearly displayed a functional response, whereas females facing rich environmental conditions did not show any functional response. These results demonstrate how the use of a given habitat relative to its availability strongly varies in response to environmental conditions. Our findings highlight that the same habitat composition can lead to very different habitat selection processes across contrasted environments. PMID- 29572511 TI - Double deletion of tetraspanins CD9 and CD81 in mice leads to a syndrome resembling accelerated aging. AB - Chronic obstructive pulmonary disease (COPD) has been recently characterized as a disease of accelerated lung aging, but the mechanism remains unclear. Tetraspanins have emerged as key players in malignancy and inflammatory diseases. Here, we found that CD9/CD81 double knockout (DKO) mice with a COPD-like phenotype progressively developed a syndrome resembling human aging, including cataracts, hair loss, and atrophy of various organs, including thymus, muscle, and testis, resulting in shorter survival than wild-type (WT) mice. Consistent with this, DNA microarray analysis of DKO mouse lungs revealed differential expression of genes involved in cell death, inflammation, and the sirtuin-1 (SIRT1) pathway. Accordingly, expression of SIRT1 was reduced in DKO mouse lungs. Importantly, siRNA knockdown of CD9 and CD81 in lung epithelial cells additively decreased SIRT1 and Foxo3a expression, but reciprocally upregulated the expression of p21 and p53, leading to reduced cell proliferation and elevated apoptosis. Furthermore, deletion of these tetraspanins increased the expression of pro-inflammatory genes and IL-8. Hence, CD9 and CD81 might coordinately prevent senescence and inflammation, partly by maintaining SIRT1 expression. Altogether, CD9/CD81 DKO mice represent a novel model for both COPD and accelerated senescence. PMID- 29572512 TI - Cultured bloodstream Trypanosoma brucei adapt to life without mitochondrial translation release factor 1. AB - Trypanosoma brucei is an extracellular parasite that alternates between an insect vector (procyclic form) and the bloodstream of a mammalian host (bloodstream form). While it was previously reported that mitochondrial release factor 1 (TbMrf1) is essential in cultured procyclic form cells, we demonstrate here that in vitro bloodstream form cells can tolerate the elimination of TbMrf1. Therefore, we explored if this discrepancy is due to the unique bioenergetics of the parasite since procyclic form cells rely on oxidative phosphorylation; whereas bloodstream form cells utilize glycolysis for ATP production and FoF1 ATPase to maintain the essential mitochondrial membrane potential. The observed disruption of intact bloodstream form FoF1-ATPases serves as a proxy to indicate that the translation of its mitochondrially encoded subunit A6 is impaired without TbMrf1. While these null mutants have a decreased mitochondrial membrane potential, they have adapted by increasing their dependence on the electrogenic contributions of the ADP/ATP carrier to maintain the mitochondrial membrane potential above the minimum threshold required for T. brucei viability in vitro. However, this inefficient compensatory mechanism results in avirulent mutants in mice. Finally, the depletion of the codon-independent release factor TbPth4 in the TbMrf1 knockouts further exacerbates the characterized mitchondrial phenotypes. PMID- 29572513 TI - Hybrid graphene/cadmium-free ZnSe/ZnS quantum dots phototransistors for UV detection. AB - Graphene-based optoelectronic devices have attracted much attention due to their broadband photon responsivity and fast response time. However, the performance of such graphene-based photodetectors is greatly limited by weak light absorption and low responsivity induced by the gapless nature of graphene. Here, we achieved a high responsivity above 103 AW-1 for Ultraviolet (UV) light in a hybrid structure based phototransistor, which consists of CVD-grown monolayer graphene and ZnSe/ZnS core/shell quantum dots. The photodetectors exhibit a selective photo responsivity for the UV light with the wavelength of 405 nm, confirming the main light absorption from QDs. The photo-generated charges have been found to transfer from QDs to graphene channel, leading to a gate-tunable photo responsivity with the maximum value obtained at V G about 15V. A recirculate 100 times behavior with a good stability of 21 days is demonstrated for our devices and another flexible graphene/QDs based photoconductors have been found to be functional after 1000 bending cycles. Such UV photodetectors based on graphene decorated with cadmium-free ZnSe/ZnS quantum dots offer a new way to build environmental friendly optoelectronics. PMID- 29572514 TI - Magnetic domain interactions of Fe3O4 nanoparticles embedded in a SiO2 matrix. AB - Currently, superparamagnetic functionalized systems of magnetite (Fe3O4) nanoparticles (NPs) are promising options for applications in hyperthermia therapy, drug delivery and diagnosis. Fe3O4 NPs below 20 nm have stable single domains (SSD), which can be oriented by magnetic field application. Dispersion of Fe3O4 NPs in silicon dioxide (SiO2) matrix allows local SSD response with uniaxial anisotropy and orientation to easy axis, 90 degrees <001> or 180 degrees <111>. A successful, easy methodology to produce Fe3O4 NPs (6-17 nm) has been used with the Stober modification. NPs were embedded in amorphous and biocompatible SiO2 matrix by mechanical stirring in citrate and tetraethyl orthosilicate (TEOS). Fe3O4 NPs dispersion was sampled in the range of 2-12 h to observe the SiO2 matrix formation as time function. TEM characterization identified optimal conditions at 4 h stirring for separation of SSD Fe3O4 in SiO2 matrix. Low magnetization (Ms) of 0.001 emu and a coercivity (Hc) of 24.75 Oe indicate that the embedded SSD Fe3O4 in amorphous SiO2 reduces the Ms by a diamagnetic barrier. Magnetic force microscopy (MFM) showed SSD Fe3O4 of 1.2 nm on average embedded in SiO2 matrix with uniaxial anisotropy response according to Fe3+ and Fe2+ electron spin coupling and rotation by intrinsic Neel contribution. PMID- 29572515 TI - Neuronal differentiation induces SNORD115 expression and is accompanied by post transcriptional changes of serotonin receptor 2c mRNA. AB - The serotonin neurotransmitter system is widespread in the brain and implicated in modulation of neuronal responses to other neurotransmitters. Among 14 serotonin receptor subtypes, 5-HT2cR plays a pivotal role in controlling neuronal network excitability. Serotonergic activity conveyed through receptor 5-HT2cR is regulated post-transcriptionally via two mechanisms, alternative splicing and A to-I RNA editing. Brain-specific small nucleolar RNA SNORD115 harbours a phylogenetically conserved 18-nucleotide antisense element with perfect complementarity to the region of 5ht2c primary transcript that undergoes post transcriptional changes. Previous 5ht2c minigene studies have implicated SNORD115 in fine-tuning of both post-transcriptional events. We monitored post transcriptional changes of endogenous 5ht2c transcripts during neuronal differentiation. Both SNORD115 and 5ht2c were upregulated upon neuronal commitment. We detected increased 5ht2c alternative exon Vb inclusion already at the stage of neuronal progenitors, and more extensive A-to-I editing of non targeted sites A and B compared to adjacent adenosines at sites E, C and D throughout differentiation. As the extent of editing is known to positively correlate with exon Vb usage while it reduces receptor functionality, our data support the model where SNORD115 directly promotes alternative exon inclusion without the requirement for conversion of key adenosines to inosines, thereby favouring production of full-length receptor isoforms with higher potency. PMID- 29572516 TI - Time-dependent memory transformation along the hippocampal anterior-posterior axis. AB - With time, memories undergo a neural reorganization that is linked to a transformation of detailed, episodic into more semantic, gist-like memory. Traditionally, this reorganization is thought to involve a redistribution of memory from the hippocampus to neocortical areas. Here we report a time-dependent reorganization within the hippocampus, along its anterior-posterior axis, that is related to the transformation of detailed memories into gist-like representations. We show that mnemonic representations in the anterior hippocampus are highly distinct and that anterior hippocampal activity is associated with detailed memory but decreases over time. Posterior hippocampal representations, however, are more gist-like at a later retention interval, and do not decline over time. These findings indicate that, in addition to the well known systems consolidation from hippocampus to neocortex, there are changes within the hippocampus that are crucial for the temporal dynamics of memory. PMID- 29572517 TI - Effect of tropical forest disturbance on the competitive interactions within a diverse ant community. AB - Understanding how anthropogenic disturbance influences patterns of community composition and the reinforcing interactive processes that structure communities is important to mitigate threats to biodiversity. Competition is considered a primary reinforcing process, yet little is known concerning disturbance effects on competitive interaction networks. We examined how differences in ant community composition between undisturbed and disturbed Bornean rainforest, is potentially reflected by changes in competitive interactions over a food resource. Comparing 10 primary forest sites to 10 in selectively-logged forest, we found higher genus richness and diversity in the primary forest, with 18.5% and 13.0% of genera endemic to primary and logged respectively. From 180 hours of filming bait cards, we assessed ant-ant interactions, finding that despite considered aggression over food sources, the majority of ant interactions were neutral. Proportion of competitive interactions at bait cards did not differ between forest type, however, the rate and per capita number of competitive interactions was significantly lower in logged forest. Furthermore, the majority of genera showed large changes in aggression-score with often inverse relationships to their occupancy rank. This provides evidence of a shuffled competitive network, and these unexpected changes in aggressive relationships could be considered a type of competitive network re-wiring after disturbance. PMID- 29572518 TI - The properties of fibreboard based on nanolignocelluloses/CaCO3/PMMA composite synthesized through mechano-chemical method. AB - The purpose of this study was to develop a rapid and green method for the synthesis of lignocelluloses-based materials with superior mechanical properties. Samples were produced by hot-pressed method using different concentrations of CaCO3 and poly (methyl methacrylate) particles-filled nanolignocelluloses composites which was synthesized through mechano-chemical method. Poly (methyl methacrylate) and CaCO3 nanoparticles have been used as nanofillers. Bending strength, elasticity modulus, and dimensional stability, thermal properties of the developed lignocelluloses-based composites were determined. In view of the experimental results, it is found that the composites materials have good mechanical, dimensional stability, and thermal properties which enhanced as the filler loading increased. Thus, herein described lignocelluloses-based materials showed important characteristics to be concluded that these composites are suitable to be used for the design of flooring and construction systems. PMID- 29572519 TI - Three-dimensional variations of the slab geometry correlate with earthquake distributions at the Cascadia subduction system. AB - Significant along-strike variations of seismicity are observed at subduction zones, which are strongly influenced by physical properties of the plate interface and rheology of the crust and mantle lithosphere. However, the role of the oceanic side of the plate boundary on seismicity is poorly understood due to the lack of offshore instrumentations. Here tomographic results of the Cascadia subduction system, resolved with full-wave ambient noise simulation and inversion by integrating dense offshore and onshore seismic datasets, show significant variations of the oceanic lithosphere along strike and down dip from spreading centers to subduction. In central Cascadia, where seismicity is sparse, the slab is imaged as a large-scale low-velocity feature near the trench, which is attributed to a highly hydrated and strained oceanic lithosphere underlain by a layer of melts or fluids. The strong correlation suggests that the properties of the incoming oceanic plate play a significant role on seismicity. PMID- 29572520 TI - Altered Insulin/Insulin-Like Growth Factor Signaling in a Comorbid Rat model of Ischemia and beta-Amyloid Toxicity. AB - Ischemic stroke and diabetes are vascular risk factors for the development of impaired memory such as dementia and/or Alzheimer's disease. Clinical studies have demonstrated that minor striatal ischemic lesions in combination with beta amyloid (Abeta) load are critical in generating cognitive deficits. These cognitive deficits are likely to be associated with impaired insulin signaling. In this study, we examined the histological presence of insulin-like growth factor-I (IGF-1) and insulin receptor substrate (IRS-1) in anatomically distinct brain circuits compared with morphological brain damage in a co-morbid rat model of striatal ischemia (ET1) and Abeta toxicity. The results demonstrated a rapid increase in the presence of IGF-1 and IRS-1 immunoreactive cells in Abeta + ET1 rats, mainly in the ipsilateral striatum and distant regions with synaptic links to the striatal lesion. These regions included subcortical white matter, motor cortex, thalamus, dentate gyrus, septohippocampal nucleus, periventricular region and horizontal diagonal band of Broca in the basal forebrain. The alteration in IGF-1 and IRS-1 presence induced by ET1 or Abeta rats alone was not severe enough to affect the entire brain circuit. Understanding the causal or etiologic interaction between insulin and IGF signaling and co-morbidity after ischemia and Abeta toxicity will help design more effective therapeutics. PMID- 29572521 TI - Thermal management and non-reciprocal control of phonon flow via optomechanics. AB - Engineering phonon transport in physical systems is a subject of interest in the study of materials, and has a crucial role in controlling energy and heat transfer. Of particular interest are non-reciprocal phononic systems, which in direct analogy to electric diodes, provide a directional flow of energy. Here, we propose an engineered nanostructured material, in which tunable non-reciprocal phonon transport is achieved through optomechanical coupling. Our scheme relies on breaking time-reversal symmetry by a spatially varying laser drive, which manipulates low-energy acoustic phonons. Furthermore, we take advantage of developments in the manipulation of high-energy phonons through controlled scattering mechanisms, such as using alloys and introducing disorder. These combined approaches allow us to design an acoustic isolator and a thermal diode. Our proposed device will have potential impact in phonon-based information processing, and heat management in low temperatures. PMID- 29572523 TI - Language lessons.

AB - The number of patients with dysphagia is rapidly increasing due to the ageing of the population. Therefore, the importance of objectively assessing swallowing function has received increasing attention. Videofluoroscopy and videoendoscopy are the standard clinical examinations for dysphagia, but these techniques are not suitable for daily use because of their invasiveness. Here, we aimed to develop a novel, non-invasive method for measuring swallowing function using a motion tracking system, the Kinect v2 sensor. Five males and five females with normal swallowing function participated in this study. We defined three mouth related parameters and two larynx-related parameters and recorded data from 2.5 seconds before to 2.5 seconds after swallowing onset. Changes in mouth-related parameters were observed before swallowing and reached peak values at the time of swallowing. In contrast, larynx-related parameters showed little change before swallowing and reached peak values immediately after swallowing. This simple swallow tracking system (SSTS) successfully quantified the swallowing process from the oral phase to the laryngeal phase. This SSTS is non-invasive, wireless, easy to set up, and simultaneously measures the dynamics of swallowing from the mouth to the larynx. We propose the SSTS for use as a novel and non-invasive swallowing assessment tool in the clinic. PMID- 29572524 TI - Software support for environmental evidence synthesis.

AB - Perhaps the greatest challenge facing global fisheries is that recovery often requires substantial short-term reductions in fishing effort, catches and profits. These costs can be onerous and are borne in the present; thus, many countries are unwilling to undertake such socially and politically unpopular actions. We argue that many nations can recover their fisheries while avoiding these short-term costs by sharply addressing illegal, unreported and unregulated (IUU) fishing. This can spur fishery recovery, often at little or no cost to local economies or food provision. Indonesia recently implemented aggressive policies to curtail the high levels of IUU fishing it experiences from foreign flagged vessels. We show that Indonesia's policies have reduced total fishing effort by at least 25%, illustrating with empirical evidence the possibility of achieving fishery reform without short-term losses to the local fishery economy. Compared with using typical management reforms that would require a 15% reduction in catch and 16% reduction in profit, the approach of curtailing IUU has the potential to generate a 14% increase in catch and a 12% increase in profit. Applying this model globally, we find that addressing IUU fishing could facilitate similar rapid, long-lasting fisheries gains in many regions of the world.

AB - The electrical transport and structural properties of tin oxide nanoparticles under compression have been studied by in situ impedance measurements and synchrotron X-ray diffraction (XRD) up to 27.9 GPa. It was found that the conduction of SnO2 can be improved significantly with compression. Abnormal variations in resistivity, relaxation frequency, and relative permittivity were observed at approximately 12.3 and 25.0 GPa, which can be attributed to pressure induced tetragonal- orthorhombic-cubic structural transitions. The dielectric properties of the SnO2 nanoparticles were found to be a function of pressure, and the dielectric response was dependent on frequency and pressure. The dielectric constant and loss tangent decreased with increasing frequency. Relaxation-type dielectric behaviour dominated at low frequencies. Whereas, modulus spectra indicated that charge carrier short-range motion dominated at high frequencies.

AB - Judgement bias tasks are promising tools to assess emotional valence in animals, however current designs are often time-consuming and lack aspects of validity. This study aimed to establish an improved design that addresses these issues and can be used across species. Horses, rats, and mice were trained on a spatial Go/No-go task where animals could initiate each trial. The location of an open goal-box, at either end of a row of five goal-boxes, signalled either reward (positive trial) or non-reward (negative trial). Animals first learned to approach the goal-box in positive trials (Go) and to re-initiate/not approach in negative trials (No-go). Animals were then tested for responses to ambiguous trials where goal-boxes at intermediate locations were opened. The Go:No-go response ratio was used as a measure of judgement bias. Most animals quickly learned the Go/No-go discrimination and performed trials at a high rate compared to previous studies. Subjects of all species reliably discriminated between reference cues and ambiguous cues, demonstrating a monotonic graded response across the different cue locations, with no evidence of learning about the outcome of ambiguous trials. This novel test protocol is an important step towards a practical task for comparative studies on judgement biases in animals. PMID- 29572528 TI - Cell-free protein synthesis from genomically recoded bacteria enables multisite incorporation of noncanonical amino acids. AB - Cell-free protein synthesis has emerged as a powerful approach for expanding the range of genetically encoded chemistry into proteins. Unfortunately, efforts to site-specifically incorporate multiple non-canonical amino acids into proteins using crude extract-based cell-free systems have been limited by release factor 1 competition. Here we address this limitation by establishing a bacterial cell free protein synthesis platform based on genomically recoded Escherichia coli lacking release factor 1. This platform was developed by exploiting multiplex genome engineering to enhance extract performance by functionally inactivating negative effectors. Our most productive cell extracts enabled synthesis of 1,780 +/- 30 mg/L superfolder green fluorescent protein. Using an optimized platform, we demonstrated the ability to introduce 40 identical p-acetyl-L-phenylalanine residues site specifically into an elastin-like polypeptide with high accuracy of incorporation ( >= 98%) and yield (96 +/- 3 mg/L). We expect this cell-free platform to facilitate fundamental understanding and enable manufacturing paradigms for proteins with new and diverse chemistries. PMID- 29572530 TI - Geographical variation of diabetic emergencies attended by prehospital Emergency Medical Services is associated with measures of ethnicity and socioeconomic status. AB - Geographical variation of diabetic emergencies attended by prehospital emergency medical services (EMS) and the relationship between area-level social and demographic factors and risk of a diabetic emergency were examined. All cases of hypoglycaemia and hyperglycaemia attended by Ambulance Victoria between 1/01/2009 and 31/12/2015 were tabulated by Local Government Area (LGA). Conditional autoregressive models were used to create smoothed maps of age and gender standardised incidence ratio (SIR) of prehospital EMS attendance for a diabetic emergency. Spatial regression models were used to examine the relationship between risk of a diabetic emergency and area-level factors. The areas with the greatest risk of prehospital EMS attendance for a diabetic emergency were disperse. Area-level factors associated with risk of a prehospital EMS-attended diabetic emergency were socioeconomic status (SIR 0.70 95% CrI [0.51, 0.96]), proportion of overseas-born residents (SIR 2.02 95% CrI [1.37, 2.91]) and motor vehicle access (SIR 1.47 95% CrI [1.08, 1.99]). Recognition of areas of increased risk of prehospital EMS-attended diabetic emergencies may be used to assist prehospital EMS resource planning to meet increased need. In addition, identification of associated factors can be used to target preventative interventions tailored to individual regions to reduce demand. PMID- 29572531 TI - Cross-platform mass spectrometry annotation in breathomics of oesophageal-gastric cancer. AB - Disease breathomics is gaining importance nowadays due to its usefulness as non invasive early cancer detection. Mass spectrometry (MS) technique is often used for analysis of volatile organic compounds (VOCs) associated with cancer in the exhaled breath but a long-standing challenge is the uncertainty in mass peak annotation for potential volatile biomarkers. This work describes a cross platform MS strategy employing selected-ion flow tube mass spectrometry (SIFT MS), high resolution gas chromatography-mass spectrometry (GC-MS) retrofitted with electron ionisation (EI) and GC-MS retrofitted with positive chemical ionisation (PCI) as orthogonal analytical approaches in order to provide facile identification of the oxygenated VOCs from breath of cancer patients. In addition, water infusion was applied as novel efficient PCI reagent in breathomics analysis, depicting unique diagnostic ions M+ or [M-17]+ for VOC identification. Identity confirmation of breath VOCs was deduced using the proposed multi-platform workflow, which reveals variation in breath oxygenated VOC composition of oesophageal-gastric (OG) cancer patients with dominantly ketones, followed by aldehydes, alcohols, acids and phenols in decreasing order of relative abundance. Accurate VOC identification provided by cross-platform approach would be valuable for the refinement of diagnostic VOC models and the understanding of molecular drivers of VOC production. PMID- 29572532 TI - Electrocaloric effect in cubic Hubbard nanoclusters. AB - In the paper a computational study of the electrocaloric effect is presented for a cubic nanocluster consisting of 8 sites. The system of interest is described by means of an extended Hubbard model in external electric field at half filling of the energy levels. The thermodynamic description is obtained within canonical ensemble formalism on the basis of exact numerical diagonalization of the system Hamiltonian. In particular, the entropy and the specific heat are determined as a function of temperature and external electric field. The electrocaloric effect is described quantitatively by isothermal entropy change. The behaviour of this quantity is thoroughly analysed as a function of extended Hubbard model parameters, temperature and electric field variation magnitude. The existence of direct and inverse electrocaloric effect is predicted for some range of model parameters. A high sensitivity to Hubbard model parameters is shown, what paves the way towards controlling and tuning the effect. A non-linear, quadratic dependence of isothermal entropy change on electric field variation magnitude is demonstrated. The potential for applications of electrocaloric effect in strongly correlated nanoclusters is shown. PMID- 29572533 TI - Nature-Inspired Hierarchical Steels. AB - Materials can be made strong, but as such they are often brittle and prone to fracture when under stress. Inspired by the exceptionally strong and ductile structure of byssal threads found in certain mussels, we have designed and manufactured a multi-hierarchical steel, based on an inexpensive austenitic stainless steel, which defeats this "conflict" by possessing both superior strength and ductility. These excellent mechanical properties are realized by structurally introducing sandwich structures at both the macro- and nano-scales, the latter via an isometric, alternating, dual-phase crystal phases comprising nano-band austenite and nano-lamellar martensite, without change in chemical composition. Our experiments (transmission and scanning electron microscopy, electron back-scattered diffraction, nano-indentation and tensile tests) and micromechanics simulation results reveal a synergy of mechanisms underlying such exceptional properties. This synergy is key to the development of vastly superior mechanical properties, and may provide a unique strategy for the future development of new super strong and tough (damage-tolerant), lightweight and inexpensive structural materials. PMID- 29572534 TI - The effects of hydroxyethyl starch and gelatine on pulmonary cytokine production and oedema formation. AB - Recently, side effects of plasma expanders like hydroxyethyl starch and gelatine gained considerable attention. Most studies have focused on the kidneys; lungs remain unconsidered. Isolated mouse lungs were perfused for 4 hours with buffer solutions based on hydroxyethyl starch (HES) 130/0.4, HES 200/0.5 or gelatine and ventilated with low or high pressure under physiological pH and alkalosis. Outcome parameters were cytokine levels and the wet-to-dry ratio. For cytokine release, murine and human PCLS were incubated in three different buffers and time points.In lungs perfused with the gelatine based buffer IL-6, MIP-2 and KC increased when ventilated with high pressure. Wet-to-dry ratios increased stronger in lungs perfused with gelatine - compared to HES 130/0.4. Alkalotic perfusion resulted in higher cytokine levels but normal wet-to-dry ratio. Murine PCLS supernatants showed increased IL-6 and KC when incubated in gelatine based buffer, whereas in human PCLS IL-8 was elevated. In murine IPL HES 130/0.4 has lung protective effects in comparison to gelatine based infusion solutions, especially in the presence of high-pressure ventilation. Gelatine perfusion resulted in increased cytokine production. Our findings suggest that gelatine based solutions may have side effects in patients with lung injury or lung oedema. PMID- 29572535 TI - Poly-ligand profiling differentiates trastuzumab-treated breast cancer patients according to their outcomes. AB - Assessing the phenotypic diversity underlying tumour progression requires the identification of variations in the respective molecular interaction networks. Here we report proof-of-concept for a platform called poly-ligand profiling (PLP) that surveys these system states and distinguishes breast cancer patients who did or did not derive benefit from trastuzumab. We perform tissue-SELEX on breast cancer specimens to enrich single-stranded DNA (ssDNA) libraries that preferentially interact with molecular components associated with the two clinical phenotypes. Testing of independent sample sets verifies the ability of PLP to classify trastuzumab-treated patients according to their clinical outcomes with ROC-AUC of 0.78. Standard HER2 testing of the same patients gives a ROC-AUC of 0.47. Kaplan-Meier analysis reveals a median increase in benefit from trastuzumab-containing treatments of 300 days for PLP-positive compared to PLP negative patients. If prospectively validated, PLP may increase success rates in precision oncology and clinical trials, thus improving both patient care and drug development. PMID- 29572536 TI - Dual role of YM1+ M2 macrophages in allergic lung inflammation. AB - Alternatively activated (M2 or YM1+) macrophages have been associated with the development of asthma but their contribution to disease initiation and progression remains unclear. To assess the therapeutic potential of modulating these M2 macrophages, we have studied inhibition of M2 polarisation during and after development of allergic lung inflammation by treating with cynaropicrin, a galectin-3 pathway inhibitor. Mice that were treated with this inhibitor of M2 polarisation during induction of allergic inflammation developed less severe eosinophilic lung inflammation and less collagen deposition around airways, while the airway alpha-smooth muscle actin layer was unaffected. When we treated with cynaropicrin after induction of inflammation, eosinophilic lung inflammation and collagen deposition were also inhibited though to a lesser extent. Unexpectedly, both during and after induction of allergic inflammation, inhibition of M2 polarisation resulted in a shift towards neutrophilic inflammation. Moreover, airway hyperresponsiveness was worse in mice treated with cynaropicrin as compared to allergic mice without inhibitor. These results show that M2 macrophages are associated with remodeling and development of eosinophilic lung inflammation, but prevent development of neutrophilic lung inflammation and worsening of airway hyperresponsiveness. This study suggests that macrophages contribute to determining development of eosinophilic or neutrophilic lung inflammation in asthma. PMID- 29572537 TI - Intralayer and interlayer electron-phonon interactions in twisted graphene heterostructures. AB - The understanding of interactions between electrons and phonons in atomically thin heterostructures is crucial for the engineering of novel two-dimensional devices. Electron-phonon (el-ph) interactions in layered materials can occur involving electrons in the same layer or in different layers. Here we report on the possibility of distinguishing intralayer and interlayer el-ph interactions in samples of twisted bilayer graphene and of probing the intralayer process in graphene/h-BN by using Raman spectroscopy. In the intralayer process, the el-ph scattering occurs in a single graphene layer and the other layer (graphene or h BN) imposes a periodic potential that backscatters the excited electron, whereas for the interlayer process the el-ph scattering occurs between states in the Dirac cones of adjacent graphene layers. Our methodology of using Raman spectroscopy to probe different types of el-ph interactions can be extended to study any kind of graphene-based heterostructure. PMID- 29572538 TI - In vivo depletion of serum IgG by an affibody molecule binding the neonatal Fc receptor. AB - Lowering the total level of Immunoglobulin G (IgG) in circulation is a promising general treatment option for many autoimmune diseases driven by pathogenic autoantibodies. The half-life of IgG in circulation is unusually long as a consequence of its interaction with the neonatal Fc receptor (FcRn), which protects it from lysosomal degradation by cells in contact with blood. Blocking the IgG/FcRn interaction prevents FcRn-mediated rescue, which may lead to increased catabolism and a lowering of the total IgG level. Here, we find that an engineered alternative scaffold protein, an affibody molecule, interacting specifically with FcRn, is able to block the IgG/FcRn interaction in vitro. The affibody molecule (ZFcRn) was expressed alone or as a fusion to an albumin binding domain (ABD), to extend its half-life in circulation, in both cases with retained affinity and blocking potential. Repeated i.v. injections in mice of ZFcRn and ZFcRn-ABD were found to result in an up to 40% reduction of the IgG serum-level after 5 days. Potential applications of ZFcRn as a general treatment modality for autoimmune diseases are discussed. PMID- 29572539 TI - Methodology challenges in studying human gut microbiota - effects of collection, storage, DNA extraction and next generation sequencing technologies. AB - The information on microbiota composition in the human gastrointestinal tract predominantly originates from the analyses of human faeces by application of next generation sequencing (NGS). However, the detected composition of the faecal bacterial community can be affected by various factors including experimental design and procedures. This study evaluated the performance of different protocols for collection and storage of faecal samples (native and OMNIgene.GUT system) and bacterial DNA extraction (MP Biomedicals, QIAGEN and MO BIO kits), using two NGS platforms for 16S rRNA gene sequencing (Ilumina MiSeq and Ion Torrent PGM). OMNIgene.GUT proved as a reliable and convenient system for collection and storage of faecal samples although favouring Sutterella genus. MP provided superior DNA yield and quality, MO BIO depleted Gram positive organisms while using QIAGEN with OMNIgene.GUT resulted in greatest variability compared to other two kits. MiSeq and IT platforms in their supplier recommended setups provided comparable reproducibility of donor faecal microbiota. The differences included higher diversity observed with MiSeq and increased capacity of MiSeq to detect Akkermansia muciniphila, [Odoribacteraceae], Erysipelotrichaceae and Ruminococcaceae (primarily Faecalibacterium prausnitzii). The results of our study could assist the investigators using NGS technologies to make informed decisions on appropriate tools for their experimental pipelines. PMID- 29572540 TI - Pulsed electromagnetic fields increase osteogenetic commitment of MSCs via the mTOR pathway in TNF-alpha mediated inflammatory conditions: an in-vitro study. AB - Pulsed electromagnetic fields (PEMFs) have been considered a potential treatment modality for fracture healing, however, the mechanism of their action remains unclear. Mammalian target of rapamycin (mTOR) signaling may affect osteoblast proliferation and differentiation. This study aimed to assess the osteogenic differentiation of mesenchymal stem cells (MSCs) under PEMF stimulation and the potential involvement of mTOR signaling pathway in this process. PEMFs were generated by a novel miniaturized electromagnetic device. Potential changes in the expression of mTOR pathway components, including receptors, ligands and nuclear target genes, and their correlation with osteogenic markers and transcription factors were analyzed. Involvement of the mTOR pathway in osteogenesis was also studied in the presence of proinflammatory mediators. PEMF exposure increased cell proliferation and adhesion and the osteogenic commitment of MSCs even in inflammatory conditions. Osteogenic-related genes were over expressed following PEMF treatment. Our results confirm that PEMFs contribute to activation of the mTOR pathway via upregulation of the proteins AKT, MAPP kinase, and RRAGA, suggesting that activation of the mTOR pathway is required for PEMF stimulated osteogenic differentiation. Our findings provide insights into how PEMFs influence osteogenic differentiation in normal and inflammatory environments. PMID- 29572541 TI - Dimer Interface of the Human Serotonin Transporter and Effect of the Membrane Composition. AB - The oligomeric state of membrane proteins has recently emerged in many cases as having an effect on their function. However, the intrinsic dynamics of their spatial organization in cells and model systems makes it challenging to characterize. Here we use molecular dynamics (MD) simulations at multiple resolutions to determine the dimer conformation of the human serotonin transporter (hSERT). From self-assembly simulations we predict dimer candidates and subsequently quantify their relative strength. We use umbrella sampling (US) replica exchange MD simulations for which we present extensive analysis of their efficiency and improved sampling compared to regular US MD simulations. The data shows that the most stable hSERT dimer interface is symmetrical and involves transmembrane helix 12 (TM12), similar to the crystal structure of the bacterial homologue LeuT, but with a slightly different orientation. We also describe the supramolecular organization of hSERT from a 250 MUs self-assembly simulation. Finally, the effects of the presence of phosphatidylinositol bisphosphate or cholesterol in the membrane model has been quantified for the TM12-TM12 predicted interface. Collectively, the presented data bring new insight to the area of protein and lipid interplay in biological membranes. PMID- 29572542 TI - Aryl hydrocarbon receptor signaling promotes ORMDL3-dependent generation of sphingosine-1-phosphate by inhibiting sphingosine-1-phosphate lyase. AB - Aryl hydrocarbon receptor (AhR), a cellular chemical sensor, controls cellular homeostasis, and sphingosine-1-phosphate (S1P), a bioactive intermediate of sphingolipid metabolism, is believed to have a role in immunity and inflammation, but their potential crosstalk is currently unknown. We aimed to determine whether there is a functional linkage between AhR signaling and sphingolipid metabolism. We showed that AhR ligands, including an environmental polycyclic aromatic hydrocarbon (PAH), induced S1P generation, and inhibited S1P lyase (S1PL) activity in resting cells, antigen/IgE-activated mast cells, and mouse lungs exposed to the AhR ligand alone or in combination with antigen challenge. The reduction of S1PL activity was due to AhR-mediated oxidation of S1PL at residue 317, which was reversible by the addition of an antioxidant or in cells with knockdown of the ORMDL3 gene encoding an ER transmembrane protein, whereas C317A S1PL mutant-transfected cells were resistant to the AhR-mediated effect. Furthermore, analysis of AhR ligand-treated cells showed a time-dependent increase of the ORMDL3-S1PL complex, which was confirmed by FRET analysis. This change increased the S1P levels, which in turn, induced mast cell degranulation via S1PR2 signaling. In addition, elevated levels of plasma S1P were found in children with asthma compared to non-asthmatic subjects. These results suggest a new regulatory pathway whereby the AhR-ligand axis induces ORMDL3-dependent S1P generation by inhibiting S1PL, which may contribute to the expression of allergic diseases.

AB - NETosis is a regulated form of neutrophil cell death that contributes to the host defense against pathogens and was linked to various diseases soon after its first description in 2004. During NETosis, neutrophils release neutrophil extracellular traps (NETs), which can capture and kill bacteria and other pathogens to prevent them from spreading. Although substantial progress has been made in our understanding of NETosis, the precise mechanism underlying NETosis is still a matter of debate. Research continues to elucidate the molecular pathways involved in NETosis. In recent years, interactions with the complement and coagulation systems have become increasingly apparent. Activated complement proteins can stimulate NET formation, and NETs, in turn, can serve as a platform for complement activation. In addition, NETs can act as a scaffold for thrombus formation during coagulation. While crosstalk between the coagulation and complement systems has been previously described, NETosis appears to be a third important player in this consortium to protect the host against pathogens. This review summarizes our current knowledge on the mutual interactions between NETosis, the complement system and the coagulation system, with an emerging description of their complex triangular relationship. PMID- 29572546 TI - The role of CD6 in autoimmune diseases. PMID- 29572547 TI - Mycobacterium tuberculosis Mce2E suppresses the macrophage innate immune response and promotes epithelial cell proliferation. AB - The intracellular pathogen Mycobacterium tuberculosis (Mtb) can survive in the host and cause disease by interfering with a variety of cellular functions. The mammalian cell entry 2 (mce2) operon of Mtb has been shown to contribute to tuberculosis pathogenicity. However, little is known about the regulatory roles of Mtb Mce2 family proteins towards host cellular functions. Here we show that the Mce2 family protein Mce2E suppressed the macrophage innate immune response and promoted epithelial cell proliferation. Mce2E inhibited activation of the extracellular signal-regulated kinase (ERK) and Jun N-terminal kinase (JNK) mitogen-activated protein kinase (MAPK) signaling pathways in a non-canonical D motif (a MAPK-docking motif)-dependent manner, leading to reduced expression of TNF and IL-6 in macrophages. Furthermore, Mce2E promoted proliferation of human lung epithelium-derived lung adenoma A549 cells by inhibiting K48-linked polyubiquitination of eEF1A1 in a beta strand region-dependent manner. In summary, Mce2E is a novel multifunctional Mtb virulence factor that regulates host cellular functions in a niche-dependent manner. Our data suggest a potential novel target for TB therapy. PMID- 29572548 TI - T cells from induced and spontaneous models of SLE recognize a common T cell epitope on beta2-glycoprotein I. AB - Systemic lupus erythematosus is a prototypic model for B-cell epitope spread in autoimmunity. Autoantibodies to numerous molecularly distinct self-antigens emerge in a sequential manner over several years, leading to disease manifestations. Among the earliest autoantibodies to appear are those targeting phospholipid-binding proteins, particularly beta2-glycoprotein I. Notably, mice immunized with beta2-glycoprotein I and lipopolysaccharide develop a strong T cell response to beta2-glycoprotein I that is associated with autoantibody production and renal disease, similar to that seen in human SLE. Here we hypothesized that mice with murine systemic lupus erythematosus, whether induced or spontaneous, should have T cells that recognize beta2-glycoprotein I. We evaluated the response of splenic T cells from mice with induced (C57BL/6 and C3H/HeN) and spontaneous (MRL/lpr) systemic lupus erythematosus to peptides spanning the entire sequence of human beta2GPI. We found that mice with induced and spontaneous systemic lupus erythematosus recognize a common T cell epitope (peptide 31; LYRDTAVFECLPQHAMFG) in domain III of beta2-glycoprotein I. beta2GPI reactive CD4+ T cells from the two models differed primarily in cytokine production: T cells from mice with induced SLE expressed IFN-gamma, while T cells from MRL/lpr mice expressed both IL-17 and IFN-gamma, indicating that IL-17 expressing T cells are not necessary for generating a beta2GPI-reactive T cell response. These data suggest that the generation of a beta2-glycoprotein I reactive T cell response is shared by both induced and spontaneous models of systemic lupus erythematosus and that this T cell response may mediate epitope spread to autoantibodies in both models. PMID- 29572549 TI - Mechanistic insights into cancer immunity and immunotherapy. PMID- 29572550 TI - Delayed allogeneic skin graft rejection in CD26-deficient mice. AB - Organ transplantation is an effective therapeutic tool for treating many terminal diseases. However, one of the biggest challenges of transplantation is determining how to achieve the long-term survival of the allogeneic or xenogeneic transplant by, for example, preventing transplant rejection. In the current study, CD26 gene-knockout mice were used to investigate the potential role of CD26/dipeptidyl peptidase-4 (DPPIV) in allogeneic skin graft rejection by tail skin transplantation. Compared with wild-type (CD26+/+) counterparts, CD26-/- mice showed reduced necrosis of grafts and delayed graft rejection after skin transplantation. Concentrations of serum IgG, including its subclasses IgG1 and IgG2a, were significantly reduced in CD26-/- mice during graft rejection. Moreover, after allogeneic skin transplantation, the secretion levels of the cytokines IFN-gamma, IL-2, IL-6, IL-4, and IL-13 were significantly reduced, whereas the level of the cytokine IL-10 was increased in the serum of CD26-/- mice compared with that in the serum of CD26+/+ mice. Additionally, the concentration of IL-17 in serum and the percentage of cells secreting IL-17 in mouse peripheral blood lymphocytes (MPBLs) were both significantly lower, while the percentage of regulatory T cells (Tregs) was significantly higher in MPBLs of CD26-/- mice than in those of CD26+/+ mice. Furthermore, a lower percentage of CD8+ T cells in MPBLs and fewer infiltrated macrophages and T cells in graft tissues of CD26-/- mice were detected during graft rejection. These results indicate that CD26 is involved in allogeneic skin graft rejection and provides another hint that CD26 deficiency leads to less rejection due to lower activation and proliferation of host immune cells. PMID- 29572551 TI - Lack of evidence supporting a role of TMC4-rs641738 missense variant-MBOAT7- intergenic downstream variant-in the Susceptibility to Nonalcoholic Fatty Liver Disease. AB - Current knowledge on the genetic basis of nonalcoholic fatty liver disease (NAFLD) suggests that variants contributing not only to the disease predisposition but histological severity as well are located in genes that regulate lipid metabolism. We explored the role of rs641738 C/T located in TMC4 (transmembrane channel-like 4) exon 1 (p.Gly17Glu) and 500 bases- downstream of MBOAT7 gene (TMC4/MBOAT7), in the genetic risk for developing NAFLD in a case control study. Our sample included 634 individuals (372 patients with NAFLD diagnosed by liver biopsy and 262 control subjects); genotyping was performed by a Taqman assay. Genotype frequencies in controls (CC: 84, CT: 137, TT: 41) and patients (CC: 134, CT: 178, TT: 60) were in Hardy-Weinberg equilibrium; minor allele frequency 40.8%. Our sample had 84-99% power if an additive genetic model is assumed for estimated odds ratios of 1.3-1.5, respectively. We found no evidence of association between rs641738 and either NAFLD (Cochran-Armitage test for trend, p = 0.529) or the disease severity (p = 0.61). Low levels of MBOAT7 protein expression were found in the liver of patients with NAFLD, which were unrelated to the rs641738 genotypes. In conclusion, the role of rs641738 in the pathogenesis of NAFLD is inconclusive. PMID- 29572552 TI - Dietary carbohydrates: a review of international recommendations and the methods used to derive them. AB - BACKGROUND/OBJECTIVES: Renewed dietary recommendations for carbohydrates have recently been published by various international health authorities. The present work (1) reviews the methods and processes (systematic approach/review, inclusion of public consultation) used to identify, select and grade the evidence underpinning the recommendations, particularly for total carbohydrate (CHO), fibre and sugar consumption, and (2) examines the extent to which variation in the methods and processes applied relates to any differences in the final recommendations. SUBJECTS/METHODS: A search of WHO, US, Canada, Australia and European sources identified 19 documents from 13 authorities with the desired detailed information. Processes and methods applied to derive recommendations were compiled and compared. RESULTS: (1) A relatively high total CHO and fibre intake and limited intake of (added or free) sugars are generally recommended. (2) Even where recommendations are similar, the specific justifications for quantitative/qualitative recommendations differ across authorities. (3) Differences in recommendations mainly arise from differences in the underlying definitions of CHO exposure and classifications, the degree to which specific CHO providing foods and food components were considered, and the choice and number of health outcomes selected. (4) Differences in the selection of source material, time frames or data aggregation and grading methods appeared to have minor influence. CONCLUSIONS: Despite general consistency, apparent differences among the recommendations of different authorities would likely be minimized by: (1) More explicit quantitative justifications for numerical recommendations and communication of uncertainty, and (2) greater international harmonization, particularly in the underlying definitions of exposures and range of relevant nutrition-related outcomes. PMID- 29572553 TI - Galantamine anti-colitic effect: Role of alpha-7 nicotinic acetylcholine receptor in modulating Jak/STAT3, NF-kappaB/HMGB1/RAGE and p-AKT/Bcl-2 pathways. AB - Vagal stimulation controls systemic inflammation and modulates the immune response in different inflammatory conditions, including inflammatory bowel diseases (IBD). The released acetylcholine binds to alpha-7 nicotinic acetylcholine receptor (alpha7 nAChR) to suppress pro-inflammatory cytokines. This provides a new range of potential therapeutic approaches for controlling inflammatory responses. The present study aimed to assess whether galantamine (Galan) anti-inflammatory action involves alpha7 nAChR in a 2,4,6-trinitrobenzene sulfonic acid (TNBS) model of colitis and to estimate its possible molecular pathways. Rats were assigned into normal, TNBS, sulfasalazine (Sulfz), Galan treated (10 mg/kg), methyllycaconitine (MLA; 5.6 mg/kg), and MLA + Galan groups. Drugs were administered orally once per day (11 days) and colitis was induced on the 8th day. Galan reduced the TNBS-induced ulceration, colon mass index, colonic MDA, neutrophils adhesion and infiltration (ICAM-1/MPO), inflammatory mediators (NF-kappaB, TNF-alpha, HMGB1, and RAGE), while increased the anti-apoptotic pathway (p-Akt/Bcl-2). Mechanistic study revealed that Galan increased the anti inflammatory cytokine IL-10, phosphorylated Jak2, while reduced the inflammation controller SOCS3. However, combining MLA with Galan abrogated the beneficial anti inflammatory/anti-apoptotic signals. The results of the present study indicate that Galan anti-inflammatory/-apoptotic/ -oxidant effects originate from the stimulation of the peripheral alpha7 nAChR, with the involvement of the Jak2/SOCS3 signaling pathway. PMID- 29572554 TI - MultiBacMam Bimolecular Fluorescence Complementation (BiFC) tool-kit identifies new small-molecule inhibitors of the CDK5-p25 protein-protein interaction (PPI). AB - Protein-protein interactions (PPIs) are at the core of virtually all biological processes in cells. Consequently, targeting PPIs is emerging at the forefront of drug discovery. Cellular assays which closely recapitulate native conditions in vivo are instrumental to understand how small molecule drugs can modulate such interactions. We have integrated MultiBacMam, a baculovirus-based mammalian gene delivery tool we developed, with bimolecular fluorescence complementation (BiFC), giving rise to a highly efficient system for assay development, identification and characterization of PPI modulators. We used our system to analyze compounds impacting on CDK5-p25 PPI, which is implicated in numerous diseases including Alzheimer's. We evaluated our tool-kit with the known inhibitor p5T, and we established a mini-screen to identify compounds that modulate this PPI in dose response experiments. Finally, we discovered several compounds disrupting CDK5 p25 PPI, which had not been identified by other screening or structure-based methods before. PMID- 29572555 TI - Ameliorating Effects of Leaf Water Extract of Three Aromatic Plant Species on Ozone-Polluted Snap Bean (Phaseolus vulgaris L. 'Jiangjunyoudou'). AB - Ozone (O3) is one of the major pollutants in near-surface air. In order to protect sensitive plants from O3 pollution, many kinds of protectants including synthetic ones, were assessed in previous studies. Although they have certain protective effects, some of them are not environment-friendly. In the present study, leaf water extracts of aromatic plants [Plectranthus hadiensis var. tomentosus (PHT), Pelargonium hortorum (PHB), Tagetes patula (TP)] were compared for mitigating the damages caused by O3 (150 ppb for 3 days, 8 h day-1) on snap bean (Phaseolus vulgaris 'Jiangjunyoudou'). Our results showed that O3 fumigation impaired plasma membrane, decreased chlorophyll content, increased contents of malondialdehyde and superoxide anion, inhibited photosynthesis, and caused visible injury. Leaf water extracts of PHT, PHB or TP ameliorated the negative effects of O3. Among them, extract of PHT showed the greatest potential to alleviate the O3-caused injury, followed by PHB and TP. PMID- 29572556 TI - Good clinical and functional outcomes at mid-term following autologous osteochondral transplantation for osteochondral lesions of the talus. AB - PURPOSE: Autologous osteochondral transplantation is an established treatment for large-sized osteochondral lesions of the talus (OLT) with excellent short term outcomes. However, few studies assess the outcomes of autologous osteochondral transplantation at mid-term follow-up. The purpose of the current systematic review was to evaluate the clinical outcomes of the autologous osteochondral transplantation procedure in the treatment of OLT at mid-term and long-term follow-up. METHODS: A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in October 2017 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Clinical outcomes, and complications were also evaluated. RESULTS: Eleven studies, with 500 ankles were included at a mean 62.8 months follow-up. Seven studies used the American Orthopaedic Foot and Ankle Society (AOFAS) score. The weighted mean preoperative AOFAS score was 55.1 +/- 6.1, and the postoperative score was 86.2 +/- 4.5, with 87.4% of patients (132 of 151) being reported as excellent or good results. In total, 53 of the 500 patients (10.6%) had complications. The most common complication was donor site morbidity with 18 patients (3.6%) at final follow-up. Thirty-one patients (6.2%) underwent reoperations, and 5 ankles (1.0%) were regarded as failed autologous osteochondral transplantation. CONCLUSION: The current systematic review demonstrated that good clinical and functional outcomes can be expected following autologous osteochondral transplantation for the treatment of OLT, with a low failure rate. The results from this study show patients can be reasonably counselled to expect good clinical outcomes in the mid term. MRI and radiographs showed restoration of articular surface as well as a minimal presence of osteoarthritis at mid-term follow-up. However, as low level and quality of evidence and the variability of the data may confound the data, further well-designed studies are necessary to determine the effectiveness of autologous osteochondral transplantation in the treatment for OLT.

PMID- 29572559 TI - An Integrative Review of Empirical Research on Perceptions and Behaviors Related to Prescribed Burning and Wildfire in the United States. AB - Social science research from a variety of disciplines has generated a collective understanding of how individuals prepare for, and respond to, the risks associated with prescribed burning and wildfire. We provide a systematic compilation, review, and quantification of dominant trends in this literature by collecting all empirical research conducted within the U.S. that has addressed perceptions and behaviors surrounding various aspects of prescribed burning and wildfire. We reviewed and quantified this literature using four thematic categories covering: (1) the theory and methods that have been used in previous research; (2) the psychosocial aspects of prescribed burning and wildfire that have been studied; (3) the biophysical characteristics of the fires which have been studied; and (4) the types of fire and management approaches that have been examined. Our integrative review builds on previous literature reviews on the subject by offering new insight on the dominant trends, underutilized approaches, and under-studied topics within each thematic category. For example, we found that a select set of theories (e.g., Protection Motivation Theory, Attribution Theory, etc.) and approaches (e.g., mixed-methods) have only been used sparingly in previous research, even though these theories and approaches can produce insightful results that can readily be implemented by fire-management professionals and decision makers. By identifying trends and gaps in the literature across the thematic categories, we were able to answer four questions that address how future research can make the greatest contribution to our understanding of perceptions and behaviors related to prescribed burning and wildfire. PMID- 29572558 TI - Modulation of sodium channels as pharmacological tool for pain therapy-highlights and gaps. AB - Voltage-gated sodium channels are crucially involved in the transduction and transmission of nociceptive signals and pathological pain states. In the past decades, a lot of effort has been spent examining and characterizing biophysical properties of the different sodium channels and their role in signaling pathways. Several gains of function mutations of the sodium channels Nav1.7, Nav1.8, and Nav1.9 are associated with pain disorders. Due to their critical role in nociceptive pathways voltage-gated sodium channels are regarded interesting targets for pharmacological pain treatment. However we still need to fill the gap that exists in the translation of efficacy in preclinical in vitro experiments and in models of pain into the clinic. This review summarizes biological and electrophysiological properties of voltage-gated sodium channels and aims to discuss limitations and promising pharmacological strategies in sodium channel research in the context of pain therapy. PMID- 29572560 TI - Cell permeability and nuclear DNA staining by propidium iodide in basidiomycetous yeasts. AB - Non-model yeasts within basidiomycetes have considerable importance in agriculture, industry, and environment, but they are not as well studied as ascomycetous yeasts. Serving as a basic technique, nuclear DNA staining is widely used in physiology, ecology, cell biology, and genetics. However, it is unclear whether the classical nuclear DNA staining method for ascomycetous yeasts is applicable to basidiomycetous yeasts. In this study, 5 yeasts ineffectively stained by the classical propidium iodide (PI) staining method were identified from 23 representative basidiomycetous yeasts. Pretreatment of cells using dimethyl sulfoxide (DMSO) or snailase markedly improved cell penetration to PI and thus enabled DNA content determination by flow cytometry on the recalcitrant yeasts. The pretreatments are efficient, simple, and fast, avoiding tedious mutagenesis or genetic engineering used in previous reports. The heterogeneity of cell penetration to PI among basidiomycetous yeasts was attributed to the discrepancy in cell wall polysaccharides instead of capsule or plasma membrane. This study also indicated that care must be taken in attributing PI-negative staining as viable cells when studying non-model microorganisms. PMID- 29572562 TI - Autosomal Recessive Osteogenesis Imperfecta Caused by a Novel Homozygous COL1A2 Mutation. AB - Osteogenesis imperfecta (OI) is a skeletal dysplasia characterized by brittle bones and extraskeletal manifestations. The disease phenotype varies greatly. Most commonly, OI arises from monoallelic mutations in one of the two genes encoding type I collagen, COL1A1 and COL1A2 and is inherited as an autosomal dominant trait. Here, we describe a consanguineous family with autosomal recessive OI caused by a novel homozygous glycine substitution in COL1A2, NM_000089.3: c.604G>A, p.(Gly202Ser), detected by whole-genome sequencing. The index patient is a 31-year-old Greek woman with severe skeletal fragility. She had mild short stature, low bone mineral density of the lumbar spine and blue sclerae. She had sustained multiple long bone and vertebral fractures since childhood and had been treated with bisphosphonates for several years. She also had an affected sister with similar clinical manifestations. Interestingly, the parents and one sister, all carriers of the COL1A2 glycine mutation, did not have manifestations of OI. In summary, we report on autosomal recessive OI caused by a homozygous glycine-to-serine substitution in COL1A2, leading to severe skeletal fragility. The mutation carriers lacked OI manifestations. This family further expands the complex genetic spectrum of OI and underscores the importance of genetic evaluation for correct genetic counselling. PMID- 29572561 TI - Autoimmune disorders are common in myelodysplastic syndrome patients and confer an adverse impact on outcomes. AB - The coexistence of autoimmune disorders (AD) in patients with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) has been widely recognized, although with distinct results regarding their prevalence and impact on the outcomes of the underlying hematological process. This study was aimed to analyze the prevalence, clinical characteristics, and outcomes of MDS with AD in a series of 142 patients diagnosed with MDS and CMML. AD was ascertained by both the presence of clinical symptoms or compatible serological tests. In total, 48% patients were diagnosed as having AD, being hypothyroidism the most commonly reported clinical AD (8%) and antinuclear antibodies the most frequent serological parameter identified (23.2%). The presence of AD was associated with female gender, lower hemoglobin levels, and higher IPSS-R. Overall survival for patients with AD was inferior to those with no AD (69 vs. 88% at 30 months; HR 2.75, P = 0.008). Notably, clinical but not isolated immune serological parameters had an impact on the outcomes of patients with AD. Finally, in a multivariate analysis, the presence of AD (HR 2.26) along with disease risk categories (very low and low vs. intermediate, high, and very high IPSS-R; HR 4.62) retained their independent prognostic value (P < 0.001). In conclusion, AD are prevalent in MDS and CMML patients and have prognostic implications, especially in lower-risk MDS patients.

PMID- 29572563 TI - Assessment of inter-racial variability in CYP3A4 activity and inducibility among healthy adult males of Caucasian and South Asian ancestries. AB - PURPOSE: Cytochrome P450 (CYP) 3A4 is responsible for the metabolism of more than 30% of clinically used drugs. Inherent between subject variability in clearance of CYP3A4 substrates is substantial; by way of example, midazolam clearance varies by > 10-fold between individuals before considering the impact of extrinsic factors. Relatively little is known about inter-racial variability in the activity of this enzyme. METHODS: This study assessed inter-racial variability in midazolam exposure in a cohort (n = 30) of CYP3A genotyped, age matched healthy males of Caucasian and South Asian ancestries. Midazolam exposure was assessed at baseline, following 7 days of rifampicin and following 3 days of clarithromycin. RESULTS: The geometric mean baseline midazolam area under the plasma concentration curve (AUC0-6) in Caucasians (1057 MUg/L/min) was 27% greater than South Asians (768 MUg/L/min). Similarly, the post-induction midazolam AUC0-6 in Caucasians (308 MUg/L/min) was 50% greater than South Asians (154 MUg/L/min), while the post-inhibition midazolam AUC0-6 in Caucasians (1834 MUg/L/min) was 41% greater than South Asians (1079 MUg/L/min). The difference in baseline AUC0-6 between Caucasians and South Asians was statistically significant (p <= 0.05), and a trend toward significance (p = 0.067) was observed for the post-induction AUC0-6 ratio, in both unadjusted and genotype adjusted analyses. CONCLUSIONS: Significantly higher midazolam clearance was observed in healthy age matched males of South Asian compared to Caucasian ancestry that was not explained by differences in the frequency of CYP3A genotypes. PMID- 29572565 TI - Hospital Teaching Status and Patients' Outcomes After Colon Cancer Surgery. AB - BACKGROUND AND OBJECTIVES: It is increasingly accepted that quality of colon cancer surgery might be secured by combining volume standards with audit implementation. However, debate remains about other structural factors also influencing this quality, such as hospital teaching status. This study evaluates short-term outcomes after colon cancer surgery of patients treated in general, teaching or academic hospitals. METHODS: All patients (n = 23,593) registered in the Dutch Colorectal Audit undergoing colon cancer surgery between 2011 and 2014 were included. Patients were divided into groups based on teaching status of their hospital. Main outcome measures were serious complications, failure to rescue (FTR) and 30-day or in-hospital mortality. Multivariate logistic regression models on these outcome measures and with hospital teaching status as primary determinant were used, adjusted for case-mix, year of surgery and hospital volume. RESULTS: Patients treated in teaching and academic hospitals showed higher adjusted serious complication rates, compared to patients treated in general hospitals (odds ratio 1.25 95% CI [1.11-1.39] and OR 1.23 [1.05 1.46]). However, patients treated in teaching hospitals had lower adjusted FTR rates than patients treated in general hospitals (OR 0.63 [0.44-0.89]). However, for all outcomes there was considerable between-hospitals variation within each type of teaching status. CONCLUSION: On average, patients treated in general hospitals had lower serious complication rates, but patients treated in teaching hospitals had more favorable FTR rates. Given the hospital variation within each hospital teaching type, it is possible to deliver excellent care regardless of the hospital teaching type. PMID- 29572566 TI - Functional characterization of Kv11.1 (hERG) potassium channels split in the voltage-sensing domain. AB - Voltage-dependent KCNH family potassium channel functionality can be reconstructed using non-covalently linked voltage-sensing domain (VSD) and pore modules (split channels). However, the necessity of a covalent continuity for channel function has not been evaluated at other points within the two functionally independent channel modules. We find here that by cutting Kv11.1 (hERG, KCNH2) channels at the different loops linking the transmembrane spans of the channel core, not only channels split at the S4-S5 linker level, but also those split at the intracellular S2-S3 and the extracellular S3-S4 loops, yield fully functional channel proteins. Our data indicate that albeit less markedly, channels split after residue 482 in the S2-S3 linker resemble the uncoupled gating phenotype of those split at the C-terminal end of the VSD S4 transmembrane segment. Channels split after residues 514 and 518 in the S3-S4 linker show gating characteristics similar to those of the continuous wild-type channel. However, breaking the covalent link at this level strongly accelerates the voltage-dependent accessibility of a membrane impermeable methanethiosulfonate reagent to an engineered cysteine at the N-terminal region of the S4 transmembrane helix. Thus, besides that of the S4-S5 linker, structural integrity of the intracellular S2-S3 linker seems to constitute an important factor for proper transduction of VSD rearrangements to opening and closing the cytoplasmic gate. Furthermore, our data suggest that the short and probably rigid characteristics of the extracellular S3-S4 linker are not an essential component of the Kv11.1 voltage sensing machinery. PMID- 29572568 TI - A 2-year follow-up MRI study for the evaluation of an age estimation method based on knee bone development. AB - Age estimation is an actual topic in the area of forensic medicine with a special focus on the age limits of 16 and 18 years. Current research on this topic relies on retrospective data of inhomogeneous populations relating to sex, age range, and socioeconomic status. In this work, we present a 2-year follow-up study for the evaluation of an age estimation method on a prospective magnetic resonance imaging (MRI) knee data collective of a homogeneous population. The study includes 40 male subjects from northern Germany aged 14 to 21 years. Three MRI examinations were evenly acquired within 2 years for each subject. As a first evaluation, a three-stage system was used to assess the ossification status of the knee (I:"open", II:"partially ossified", III:"fully ossified"). Three raters assessed the growth plate of the distal femur, proximal tibia, and proximal fibula based on central 2D slices. A good inter-rater agreement was attained (kappa = 0.84). All subjects younger than 18 years were rated as stage I and had a cumulative knee score (SKJ) <= 5. Based on the follow-up datasets, new parameters quantifying the intra-individual ossification process were calculated. The results of this follow-up analysis show a different start, end, and speed of each growth plate's maturation as well as an ossification peak for individuals at the age of 16. The generated MRI database provides new insights into the ossification process over time and serves as a basis for further evaluations of age estimation methods. PMID- 29572567 TI - Anti-Trichomonas vaginalis activity of ursolic acid derivative: a promising alternative. AB - Trichomonas vaginalis is an extracellular parasite that binds to the epithelium of the human urogenital tract and causes the sexually transmitted infection, trichomoniasis. In view of increased resistance to drugs belonging to the 5 nitroimidazole class, new treatment alternatives are urgently needed. In this study, eight semisynthetized triterpene derivatives were evaluated for in vitro anti-T. vaginalis activity. Ursolic acid and its derivative, 3-oxime-urs-12-en-28 oic-ursolic acid (9), presented the best anti-T. vaginalis activity when compared to other derivatives, with minimum inhibitory concentration (MIC) at 25 MUM. Moreover, 9 was active against several T. vaginalis fresh clinical isolates. Hemolysis assay demonstrated that 9 presented a low hemolytic effect. Importantly, 25 MUM 9 was not cytotoxic against the Vero cell lineage. Finally, we demonstrated that compound 9 acts synergistically with metronidazole against a T. vaginalis metronidazole-resistant isolate. This report reveals the high potential of the triterpenoid derivative 9 as trichomonicidal agent. PMID- 29572569 TI - The unprecedented 2014 Legionnaires' disease outbreak in Portugal: atmospheric driving mechanisms. AB - A large outbreak of Legionnaires' disease occurred in November 2014 nearby Lisbon, Portugal. This epidemic infected 377 individuals by the Legionella pneumophila bacteria, resulting in 14 deaths. The primary source of transmission was contaminated aerosolized water which, when inhaled, lead to atypical pneumonia. The unseasonably warm temperatures during October 2014 may have played a role in the proliferation of Legionella species in cooling tower systems. The episode was further exacerbated by high relative humidity and a thermal inversion which limited the bacterial dispersion. Here, we analyze if the Legionella outbreak event occurred during a situation of extreme potential recirculation and/or stagnation characteristics. In order to achieve this goal, the Allwine and Whiteman approach was applied for a hindcast simulation covering the affected area during a near 20-year long period (1989-2007) and then for an independent period covering the 2014 event (15 October to 13 November 2014). The results regarding the average daily critical transport indices for the 1989-2007 period clearly indicate that the airshed is prone to stagnation as these events have a dominant presence through most of the study period (42%), relatively to the occurrence of recirculation (18%) and ventilation (17%) events. However, the year of 2014 represents an exceptional year when compared to the 1989-2007 period, with 53 and 33% of the days being classified as under stagnation and recirculation conditions, respectively.

AB - OBJECTIVE: To determine frequency and type of cognitive disorders in cross sectional analysis of a Parkinson's disease (PD) cohort, and explore its relations to motor symptoms, modifiable vascular risk factors and white matter lesions (WML) volume. METHODS: In a group of 133 PD patients, mild cognitive impairment (PD-MCI) and dementia (PDD) were diagnosed according to Movement Disorders Society Task Force criteria (level 2 for PD-MCI). Detailed motor measurements were applied, including rigidity, axial, bradykinesia, tremor and postural instability gait disorders (PIGD) scores. Vascular risk was estimated by the Framingham General Cardiovascular Disease risk scoring algorithm and WML volume was measured for whole brain and frontal lobe. RESULTS: Sixty-one (46.9%) patients fulfilled criteria for PD-MCI, and 23 (17.7%) for PDD. Non-amnestic multiple domain MCI was most frequent (52% of PD-MCI patients). Motor scores were significantly higher in cognitively impaired patients, but only axial score discriminated between MCI and dementia. High vascular risk was related to impaired cognition, bradykinesia, axial, PIGD and freezing of gait (FOG) score, while whole brain WML volume was associated with PDD, FOG and attention deficits. Furthermore, high vascular risk was identified as a potential predictor of both MCI and dementia in PD. Additionally, age and bradykinesia score were independently associated with PD-MCI and age, axial score and whole brain WML volume with PDD. CONCLUSION: Cognitive disorders in PD are associated with more severe, predominantly axial motor deficits and increased, but partly modifiable vascular burden, thus opening a possibility for development of preventive strategies in PD. PMID- 29572572 TI - Osseointegration mechanisms: a proteomic approach. AB - The prime objectives in the development of biomaterials for dental applications are to improve the quality of osseointegration and to short the time needed to achieve it. Design of implants nowadays involves changes in the surface characteristics to obtain a good cellular response. Incorporating osteoinductive elements is one way to achieve the best regeneration possible post-implantation. This study examined the osteointegrative potential of two distinct biomaterials: sandblasted acid-etched titanium and a silica sol-gel hybrid coating, 70% MTMOS 30% TEOS. In vitro, in vivo, and proteomic characterisations of the two materials were conducted. Enhanced expression levels of ALP and IL-6 in the MC3T3-E1 cells cultured with coated discs, suggest that growing cells on such surfaces may increase mineralisation levels. 70M30T-coated implants showed improved bone growth in vivo compared to uncoated titanium. Complete osseointegration was achieved on both. However, coated implants displayed osteoinductive properties, while uncoated implants demonstrated osteoconductive characteristics. Coagulation related proteins attached predominantly to SAE-Ti surface. Surface properties of the material might drive the regenerative process of the affected tissue. Analysis of the proteins on the coated dental implant showed that few proteins specifically attached to its surface, possibly indicating that its osteoinductive properties depend on the silicon delivery from the implant. PMID- 29572574 TI - Polymorphism at donkey beta-lactoglobulin II locus: identification and characterization of a new genetic variant with a very low expression. AB - In the last years, donkey milk had evidenced a renewed interest as a potential functional food and a breast milk substitute. In this light, the study of the protein composition assumes an important role. In particular, beta-lactoglobulin (beta-LG), which is considered as one of the main allergenic milk protein, in donkey species consists of two molecular forms, namely beta-LG I and beta-LG II. In the present research, a genetic analysis coupled with a proteomic approach showed the presence of a new allele, here named F, which is apparently associated with a null or a severely reduced expression of beta-LG II protein. The new beta LG II F genetic variant shows a theoretical average mass (Mav) of 18,310.64 Da, a value practically corresponding with that of the variant D (?mass < 0.07 Da), but differs from beta-LG II D for two amino acid substitutions: Thr100 (variant F) -> Ala100 (variant D) and Thr118 (variant F) -> Met118 (variant D). Proteomic investigation of the whey protein fraction of an individual milk sample, homozygous FF at beta-LG II locus, allowed to identify, as very minor component, the new beta-LG II F genetic variant. By MS/MS analysis of enzymatic digests, the sequence of the beta-LG II F was characterized, and the predicted genomic data confirmed. PMID- 29572573 TI - Longitudinal Evaluation of Swallowing with Videofluoroscopy in Patients with Locally Advanced Head and Neck Cancer After Chemoradiation. AB - The aim of this study was to investigate the prevalence, severity, and pattern of evolution of swallowing impairments encountered in head and neck cancer (HNC) patients before and after chemoradiation (CRT) with videofluoroscopy of swallowing study (VFSS), using the modified barium swallow impairment profile (MBSImP) protocol and scoring system, and to determine the appropriate time points in which these patients should undergo VFSS post-CRT. A prospective cohort of 69 patients with locally advanced HNC underwent VFSS with the MBSImP protocol at 5 evaluation points: pre-CRT, and 1, 3, 6, and 12 months post-CRT. VFSS was scored with MBSImP, penetration-aspiration scale (PAS), and swallowing performance status (SPS) scale. Statistical analysis was performed only for the 12-month disease-free subset of patients. MBSImP, PAS, and SPS scale scores reached their peak at 3 months post-CRT and improved at 6-12 months, but without returning at pre-treatment levels. Base of tongue retraction, initiation of pharyngeal swallow, epiglottic movement, laryngeal vestibule closure, and laryngeal elevation were the most frequently observed impaired MBSImP components. Epiglottic movement significantly improved (p = 0.009) and laryngeal vestibule closure significantly deteriorated (p = 0.042) over time (Friedman test). Severe swallowing deficits and high aspiration rates are observed in HNC patients pre CRT, which further deteriorate post-CRT, peak at 3 months, and despite slight improvement, persist over time. We suggest that these patients, regardless of the presence of subjective dysphagia, should undergo VFSS both before and 3 months post-CRT, and also if possible, 1 month post-CRT, in order to facilitate implementation of early swallowing rehabilitation. PMID- 29572575 TI - Metastatic colonic and gastric polyps from breast cancer resembling hyperplastic polyps. AB - Breast cancer metastasis to the gastrointestinal tract is relatively rare and is generally found when patients complain of symptoms such as gastrointestinal obstruction. Herein, we report a case with metastatic colonic and gastric lesions from breast cancer, with the formation of mucosal polyps which resembled typical hyperplastic polyps.A 47-year-old woman underwent curable surgery for breast cancer and received standard systemic treatments. Her primary tumor was composed of a mix of invasive lobular and ductal carcinomas. During adjuvant endocrine therapy, she developed multiple colonic metastases, identified by colonoscopy performed as part of a general health check-up. She had no symptoms. Small elevated sessile polyps in the transverse colon and rectum showed histological features of signet-ring cell type adenocarcinoma, similar to the invasive lobular component of the primary breast cancer. During treatments for recurrent disease, she also developed multiple gastric metastases, with the same endoscopic and pathological features as the colonic lesions. Her treatment regimen was switched to oral chemotherapy, and she has since maintained stable disease for nearly 3 years. Multiple bone metastases eventually developed, and she was again switched to another systemic treatment but, to date, has remained free of symptoms.We emphasize that the endoscopic findings of the metastatic lesions in the colon and stomach in this case highly resembled hyperplastic polyps. Since biopsy is not always performed for hyperplastic polyps in the gastrointestinal tract, we believe that this case report may encourage endoscopists to offer biopsies to the patient who has a history of breast cancer. PMID- 29572576 TI - Integrated Behavioral Medicine in Cancer Care: Utilizing a Training Program Model to Provide Psychological Services in an Urban Cancer Center. AB - Psycho-oncology has come of age as its own unique subspecialty under the umbrella of oncology, vastly refining our knowledge regarding the psychosocial impact of cancer and fostering acceptance of the psychological underpinnings of the cancer experience, in turn improving the overall quality of cancer care. The importance of integrating psychological practice into the comprehensive treatment of cancer has become readily apparent, and psychosocial support services are increasing in quantity and breadth. It is the aim of this article to present a cogent argument for the proliferation of Integrated Behavioral Medicine (IBM) programs in both inpatient and outpatient clinical cancer treatment centers via an in-depth discussion of a successful IBM program including analysis of program structure, service delivery model and description of clinical services provided, and a longitudinal review of referral trends. PMID- 29572577 TI - Mechanisms of vision loss in eyes with macular edema associated with retinal vein occlusion. AB - Anti-vascular endothelial growth factor agents reduce macular edema and improve vision in eyes with macular edema associated with retinal vein occlusion (RVO), including branch RVO (BRVO) and central RVO. However, not all eyes with resolved macular edema show satisfactory best corrected visual acuity. Photoreceptor impairment can mostly explain the vision loss in these cases. Photoreceptor damage can be caused by subretinal hemorrhage in the central fovea and hard exudates or their precursor derived from concentrated lipoproteins originating from leaky retinal vessel extravasation. The contribution of neuron impairment in the inner retina, including the impairment of bipolar and ganglion cells by ischemia, indicated by the presence of a non-perfusion area (NPA), to vision loss in eyes with BRVO is insignificant. This is because the papillomacular bundle area is usually spared from NPAs in BRVO cases. PMID- 29572578 TI - Crucial role of P2X7 receptor for effector T cell activation in experimental autoimmune uveitis. AB - PURPOSE: To investigate the roles of P2X7 receptors (P2RX7) in the pathogenesis of experimental autoimmune uveoretinitis (EAU). STUDY DESIGN: Experimental. METHODS: Either wild-type (P2rx7 +/+ ) or P2rx7-deficient (P2rx7 -/- ) mice were immunized with interphotoreceptor retinoid-binding protein (IRBP) peptide 1-20. Severity of EAU was evaluated clinically and histopathologically. The induction of IRBP-specific proliferation and cytokines in draining lymph nodes was assessed by enzyme-linked immunosorbent assays (ELISA). The frequency of activation markers was examined by flow cytometry. Furthermore, inhibitory roles of systemic administration of Brilliant Blue G (BBG), an antagonist for P2RX7, in EAU were also assessed in the wild-type mice. RESULTS: The severity of EAU in P2rx7 -/- mice was reduced as compared with that in P2rx7 +/+ mice, both clinically and histopathologically. IRBP-specific proliferation in P2rx7 -/- on day 16 was slightly decreased compared to that in P2rx7 +/+ mice. The induction of IRBP specific interferon (IFN)-gamma and interleukin (IL)-17 in P2rx7 -/- mice on day 16 was lower than that in P2rx7 +/+ mice. The up-regulation of surface expression of activation markers such as CD25, CD44, and CD69 in response to TCR stimulation in P2rx7 -/- mice was decreased as compared with that in P2rx7 +/+ mice. Furthermore, neutralization of P2RX7 in vivo by BBG suppressed EAU clinically and histopathologically. IRBP-specific IFN-gamma and IL-17 induction in BBG-treated mice was significantly lower than that in vehicle-treated mice. CONCLUSION: The results suggest that P2RX7 is a novel preventative therapeutic target for uveitis as it suppresses the effector functions of both Th1 and Th17 cell responses. PMID- 29572579 TI - Surgical management of giant intrapetrous internal carotid aneurysm presenting with coil exposure after endovascular treatment. AB - Giant intrapetrous internal carotid aneurysms (petrous ICA aneurysm) are rare. A giant petrous ICA aneurysm presenting with otorrhagia and coil exposure to the external auditory meatus (EAM) after endovascular treatment has never been documented before. The authors report here a case of successful surgical trapping with bypass intervention of a giant petrous ICA aneurysm presenting with coil exposure after endovascular treatment. A 58-year-old man presented with persistent otorrhagia having been admitted to our hospital because of the recurrence of a giant petrous ICA aneurysm after repeated embolization treatments with coils. An electronic otoscope examination demonstrated that a piece of coil escaped into his right EAM. After multidisciplinary consultation, an extracranial intracranial (EC-IC) bypass with ICA occlusion and coil removal with a closed EAM filling were performed in stages. The patient recovered quickly without any neurological deficits. A digital subtraction angiography confirmed the absence of the aneurysm and patency of the bypass graft. PMID- 29572580 TI - Mere ownership of memory: motor manipulation during encoding affects memory for words. AB - Involving the body in learning increases the impact information has on memory (Johnson-Glenberg et al. in Front Psychol 7(1819):1-22, 2016), especially when that information is self-relevant (Truong et al. in J Exp Psychol Hum Percept Perform 42(3):375-385, 2016). Yet, prior research has only examined the effect of self-relevant movement (i.e., toward the self or away from the self) on memory through passive joystick flexion or extension (Oakes and Onyper in Cognit Process 18:325-333, 2017). Therefore, the current research sought to replicate the "toward: remember" and "away: forget" motor-induced self-reference effects on memory with actual body movement. Participants in two experiments took notes on a word list and either pushed notes away, pulled notes toward them, moved notes laterally, or wrote the words in a list. Results showed that participants who pulled hand-written notes toward them had better recall than those who pushed notes away from them or moved them laterally. Results suggest implicitly taking ownership of material in an embodied manner may influence how much is recalled.

Clinical trials design utilizing chemotherapy-free regimens for relapsed/refractory disease are gaining popularity. Recent studies have identified multiple genetic biomarkers that helped characterize and prognosticate different subtypes of MZL. MZLs are heterogeneous, mostly indolent, malignancies derived from B lymphocytes. Three disease subtypes are recognized, extranodal, nodal, and splenic. The disease characteristics, clinical picture, and treatment algorithms vary considerably based on subtype and site of involvement. Recent discoveries have enhanced our knowledge of the pathogenesis of MZLs leading to development of more accurate prognostic models as well as novel targeted systemic therapies.

The expanded Human Oral Microbiome Database (eHOMD) that was last updated on November 22, 2017, contains the information of approximately 772 prokaryotic species, where 70% is cultivable, and 30% belong to the uncultivable class of microorganisms along with whole genome sequences of 482 taxa. Out of 70% culturable species, 57% have already been assigned to their names. The 16S rDNA profiling of the healthy oral cavity categorized the inhabitant bacteria into six broad phyla, viz. Firmicutes, Actinobacteria, Proteobacteria, Fusobacteria, Bacteroidetes and Spirochaetes constituting 96% of total oral bacteria. These hidden oral micro-inhabitants exhibit a direct influence on human health, from host's metabolism to immune responses. Altered oral microflora has been observed in several diseases such as diabetes, bacteremia, endocarditis, cancer, autoimmune disease and preterm births. Therefore, it becomes crucial to understand the oral microbial diversity and how it fluctuates under diseased/perturbed conditions. Advances in metagenomics and next-generation sequencing techniques generate rapid sequences and provide extensive information of inhabitant microorganisms of a niche. Thus, the retrieved information can be utilized for developing microbiome-based biomarkers for their use in early diagnosis of oral and associated diseases. Besides, several apex companies have shown keen interest in oral microbiome for its diagnostic and therapeutic potential indicating a vast market opportunity. This review gives an insight of various associated aspects of the human oral microbiome. PMID- 29572582 TI - Systemic Treatment Options for Advanced-Stage Mycosis Fungoides and Sezary Syndrome. AB - PURPOSE OF REVIEW: Cutaneous T-cell lymphoma (CTCL) is a rare form of non-Hodgkin lymphoma. Globally, the most common subtypes of CTCL are mycosis fungoides and Sezary syndrome. CTCL can confer significant morbidity and even mortality in advanced disease. Here we review the current and potential future treatments for advanced-stage CTCL. RECENT FINDINGS: Heterogeneity of treatment choice has been demonstrated both in US and non-US centers. Systemic treatment choice is currently guided by prognostic features, incorporating stage, immunophenotypic and molecular findings, and patient-specific factors such as age and comorbidities. Randomized controlled studies are uncommon, and the literature is composed predominantly of retrospective, cohort, and early-phase studies. International consensus guidelines are available; however, the lack of comparative trials means that there is no clear algorithmic approach to treatment. This review article reports on the systemic treatment options in current use for advanced CTCL, and on the possible future therapies, acknowledging that an algorithmic approach is not yet forthcoming to guide treatment prioritization. PMID- 29572584 TI - Noise reduction technology reduces radiation dose in chronic total occlusions percutaneous coronary intervention: a propensity score-matched analysis. AB - Chronic total occlusions (CTO) percutaneous coronary intervention (PCI) is associated with high radiation dose. Our study aim was to evaluate the impact of the implementation of a noise reduction technology (NRT) on patient radiation dose during CTO PCI. A total of 187 CTO PCIs performed between February 2016 and May 2017 were analyzed according to the angiographic systems utilized: Standard (n = 60) versus NRT (n = 127). Propensity score matching (PSM) was performed to control for differences in baseline characteristics. Primary endpoints were Cumulative Air Kerma at Interventional Reference Point (AK at IRP), which correlates with patient's tissue reactions; and Kerma Area Product (KAP), a surrogate measure of patient's risk of stochastic radiation effects. An Efficiency Index (defined as fluoroscopy time/AK at IRP) was calculated for each procedure. Image quality was evaluated using a 5-grade Likert-like scale. After PSM, n = 55 pairs were identified. Baseline and angiographic characteristics were well matched between groups. Compared to the Standard system, NRT was associated with lower AK at IRP [2.38 (1.80-3.66) vs. 3.24 (2.04-5.09) Gy, p = 0.035], a trend towards reduction for KAP [161 (93-244) vs. 203 (136-363) Gycm2, p = 0.069], and a better Efficiency Index [16.75 (12.73-26.27) vs. 13.58 (9.92-17.63) min/Gy, p = 0.003]. Image quality was similar between the two groups (4.39 +/- 0.53 Standard vs. 4.34 +/- 0.47 NRT, p = 0.571). In conclusion, compared with a Standard system, the use of NRT in CTO PCI is associated with lower patient radiation dose and similar image quality. PMID- 29572585 TI - Comparison of silage and hay of dwarf Napier grass (Pennisetum purpureum) fed to Thai native beef bulls. AB - Both quantity and quality of forages are important in dry season feeding. Eight Thai native beef bulls were arranged in a Completely randomized design to evaluate dwarf Napier namely Sweet grass (Pennisetum purpureum cv. Mahasarakham) preserved as silage or hay on feed intake, digestibility, and rumen fermentation. The animals were fed with forage ad libitum supplemented with concentrate mixture at 1.0% of BW for 21 days; data were collected during the last 7 days. The results showed that there were differences (P < 0.05) between treatments in dry matter (DM) intake, DM digestibility, and ruminal pH, in which hay feeding gave enhanced feed intake and more favorable ruminal pH. Nevertheless, mean ruminal ammonia nitrogen, total volatile fatty acids (TVFAs), proportion of VFAs, bacterial and protozoal population, and blood urea nitrogen were similar (P > 0.05) in animals fed silage and hay. Sweet grass is better preserved as hay rather than silage. PMID- 29572586 TI - Elevated lipocalin-2 level in aqueous humor of patients with central retinal vein occlusion. AB - PURPOSE: To assess the concentrations of lipocalin-2 (LCN2) in the serum and the aqueous humor of patients with central retinal vein occlusion (CRVO). METHODS: The concentrations of LCN2 in the serum and aqueous humor of 16 cataract patients and 16 patients with CRVO with macular edema were compared. Collection of aqueous samples was conducted in the operating theater under sterile conditions and just prior to intravitreal ranibizumab injection or cataract surgery. LCN2 levels in serum and aqueous humor samples were measured using a commercial kit (human lipocalin-2/NGAL PicoKine ELISA Kit, MyBioSource Inc., USA; Catalog No: MBS175829) based on standard sandwich enzyme-linked immunosorbent assay technology. RESULTS: The concentrations of LCN2 in the aqueous humors of the CRVO group were higher than those of the control group (p = 0.021). There was no significant difference in serum LCN2 level between the two groups (p = 0.463). CONCLUSIONS: Concentrations of LCN2 in aqueous humor are increased in CRVO. LCN2 may be part of a pro-catabolic phenotype, and it may play an important role in the dreaded complications of CRVO, such as macular edema, macular ischemia, and neovascularization, which lead to blindness. PMID- 29572587 TI - Neonatal Abstinence Syndrome (NAS) in Southwestern Border States: Examining Trends, Population Correlates, and Implications for Policy. AB - Introduction Neonatal abstinence syndrome (NAS) is withdrawal syndrome in newborns following birth and is primarily caused by maternal drug use during pregnancy. This study examines trends, population correlates, and policy implications of NAS in two Southwest border states. Materials and Methods A cross sectional analysis of Hospital Inpatient Discharge Data (HIDD) was utilized to examine the incidence of NAS in the Southwest border states of Arizona (AZ) and New Mexico (NM). All inpatient hospital births in AZ and NM from January 1, 2008 through December 31, 2013 with ICD9-CM codes for NAS (779.5), cocaine (760.72), or narcotics (760.75) were extracted. Results During 2008-2013 there were 1472 NAS cases in AZ and 888 in NM. The overall NAS rate during this period was 2.83 per 1000 births (95% CI 2.68-2.97) in AZ and 5.31 (95% CI 4.96-5.66) in NM. NAS rates increased 157% in AZ and 174% in NM. NAS newborns were more likely to have low birth weight, have respiratory distress, more likely to have feeding difficulties, and more likely to be on state Medicaid insurance. AZ border region (border with Mexico) had NAS rates significantly higher than the state rate (4.06 per 1000 births [95% CI 3.68-4.44] vs. 2.83 [95% CI 2.68-2.97], respectively). In NM, the border region rate (2.09 per 1000 births [95% CI 1.48-2.69]) was significantly lower than the state rate (5.31 [95% CI 4.96-5.66]). Conclusions Despite a dramatic increase in the incidence of NAS in the U.S. and, in particular, the Southwest border states of AZ and NM, there is still scant research on the overall incidence of NAS, its assessment in the southwest border, and associated long-term outcomes. The Healthy Border (HB) 2020 binational initiative of the U.S.-Mexico Border Health Commission is an initiative that addresses several public health priorities that not only include chronic and degenerative diseases, infectious diseases, injury prevention, maternal and child health but also mental health and addiction. The growing opioid epidemic and rise in NAS cases in the Southwest border, as partially shown in this study, provides another opportunity to track health illnesses and outcomes in the Southwest border, especially because there are targeted resources through High Intensity Drug Trafficking Areas (HIDTA) funding. PMID- 29572589 TI - Low-flow anaesthesia with a fixed fresh gas flow rate. AB - During the wash-in period in low flow anaesthesia (LFA), high fresh gas flow is used to achieve the desired agent concentration. In this study, we aimed to evaluate the safety of fixed 1 L/min fresh gas flow desflurane anaesthesia in both the wash-in and maintenance periods in patients including the obese ones. 104 patients undergoing surgery under general anaesthesia were included. After endotracheal intubation, fresh gas flow was reduced to 1 L/min and the desflurane vaporizer was set at 18%. The time from opening the vaporizer to end-tidal desflurane concentration reaching 0.7 MAC was recorded (MAC 0.7 time). Throughout the surgery, hemodynamic variables, FIO2, MAC and BIS values were observed. MAC 0.7 time, BIS and MAC values at the start of surgery, number of adjustments in vaporizer settings, desflurane consumption were recorded. The average MAC 0.7 time was 2.9 +/- 0.5 min. MAC and BIS values at the start of the surgery were 0.7 (0.6-0.8) and 39 +/- 8.5 respectively. No individual patient had a BIS value above 60 throughout the surgery. Hemodynamic variables were stable and FIO2 did not fall below 30% in any patient. The number of adjustments in vaporizer settings was 56. Average desflurane consumption was 0.33 +/- 0.05 mL/min. We demonstrated that LFA without use of initial high fresh gas flow during the wash in period is an effective, safe and economic method which is easy to perform. PMID- 29572588 TI - The intracellular distribution of inorganic carbon fixing enzymes does not support the presence of a C4 pathway in the diatom Phaeodactylum tricornutum. AB - Diatoms are unicellular algae and important primary producers. The process of carbon fixation in diatoms is very efficient even though the availability of dissolved CO2 in sea water is very low. The operation of a carbon concentrating mechanism (CCM) also makes the more abundant bicarbonate accessible for photosynthetic carbon fixation. Diatoms possess carbonic anhydrases as well as metabolic enzymes potentially involved in C4 pathways; however, the question as to whether a C4 pathway plays a general role in diatoms is not yet solved. While genome analyses indicate that the diatom Phaeodactylum tricornutum possesses all the enzymes required to operate a C4 pathway, silencing of the pyruvate orthophosphate dikinase (PPDK) in a genetically transformed cell line does not lead to reduced photosynthetic carbon fixation. In this study, we have determined the intracellular location of all enzymes potentially involved in C4-like carbon fixing pathways in P. tricornutum by expression of the respective proteins fused to green fluorescent protein (GFP), followed by fluorescence microscopy. Furthermore, we compared the results to known pathways and locations of enzymes in higher plants performing C3 or C4 photosynthesis. This approach revealed that the intracellular distribution of the investigated enzymes is quite different from the one observed in higher plants. In particular, the apparent lack of a plastidic decarboxylase in P. tricornutum indicates that this diatom does not perform a C4-like CCM. PMID- 29572590 TI - Protein profiling as early detection biomarkers for TiO2 nanoparticle toxicity in Daphnia magna. AB - The mode of action for nanoparticle (NP) toxicity in aquatic organisms is not yet fully understood. In this work, a strategy other than toxicity testing was applied to Daphnia magna exposed to TiO2-NPs: the use of nuclear microscopy and the assessment of protein profile. D. magna is a keystone species broadly used as a model system in ecotoxicology. Titanium (Ti) was found in the D. magna digestive tract, mainly in the gut. The penetration of Ti into the epithelial region was greater at higher exposure levels and also observed in eggs in the brood pouch. The protein profile of individuals exposed to different concentrations showed that 2.8 and 5.6 mg/L TiO2-NP concentrations induced an over-expression of the majority of proteins, in particular proteins with molecular weight of ~120, 85 and 15 kDa, while 11.2 mg/L TiO2-NP had an inhibitory effect on protein expression. The Matrix-assisted laser desorption ionization with tandem time of flight mass spectrometry (MALDI-TOF/TOF MS) analysis of these proteins consistently identified them as vitellogenin (Vtg) like proteins, associated with enzymes involved in redox balance. These results indicate that Vtg-like proteins are up-regulated in D. magna exposed to TiO2-NPs. Vitellogenesis is associated with the reproduction system, suggesting that TiO2 NP exposure can impair reproduction by affecting this process. The precise mode of action of TiO2-NPs is still unclear and the results from this study are a first attempt to identify specific proteins as potential markers of TiO2-NP toxicity in D. magna, providing useful information for future research.

PMID- 29572591 TI - Impact of peri-operative blood transfusion on post-operative infections after radical gastrectomy for gastric cancer: a propensity score matching analysis focusing on the timing, amount of transfusion and role of leukocyte depletion. AB - PURPOSE: Allogeneic blood transfusions (BTF) are sometimes inevitable during radical gastrectomy with lymphadenectomy for advanced gastric cancer. The aim of this retrospective study was to investigate the association between BTF and post operative infections, focusing on the impact of timing, amount of transfusion and the role of leukocyte depletion. METHODS: The study cohort was 2064 patients who underwent gastrectomy for gastric cancer from November 2010 to August 2017. The association between BTF and post-operative infections was estimated by univariate and multivariate analyses after propensity score matching. Subgroup analysis was performed according to the timing and amount of transfusion, and leukocyte depletion or not. RESULTS: Out of a total 2064 patients, 426 (20.6%) received peri-operative BTF. After one-to-one matching, 361 pairs of patients were included for further analysis, of who 68 (9.4%) developed infections. Multivariate analysis identified that an operation time >= 240 min, combined multi-organ resection, BTF and BMI >= 25 kg/m2 were independent risk factors for post-operative infection. Patients given a high-volume (> 7.5 U), intra operatively of leukocyte-non-depleted BTF had the highest risk of developing infections clarified by subgroup analysis. CONCLUSION: Infection was the most common complication following gastrectomy for gastric cancer and BTF was identified as an independent risk factor by propensity score matching and multivariate analyses. The timing, amount of transfusion and leukocyte depletion had an impact on the incidence of infection. To decrease infection, BTF should be avoided where possible, particularly during operation, with a large amount and leukocyte-not-depleted blood. PMID- 29572593 TI - In response to Letter regarding "Meta-analysis of 18F-FDG PET/CT in the diagnosis of infective endocarditis". PMID- 29572594 TI - Blood pool and tissue phase patient motion effects on 82rubidium PET myocardial blood flow quantification. AB - BACKGROUND: Patient motion can lead to misalignment of left ventricular volumes of interest and subsequently inaccurate quantification of myocardial blood flow (MBF) and flow reserve (MFR) from dynamic PET myocardial perfusion images. We aimed to identify the prevalence of patient motion in both blood and tissue phases and analyze the effects of this motion on MBF and MFR estimates. METHODS: We selected 225 consecutive patients that underwent dynamic stress/rest rubidium 82 chloride (82Rb) PET imaging. Dynamic image series were iteratively reconstructed with 5- to 10-second frame durations over the first 2 minutes for the blood phase and 10 to 80 seconds for the tissue phase. Motion shifts were assessed by 3 physician readers from the dynamic series and analyzed for frequency, magnitude, time, and direction of motion. The effects of this motion isolated in time, direction, and magnitude on global and regional MBF and MFR estimates were evaluated. Flow estimates derived from the motion corrected images were used as the error references. RESULTS: Mild to moderate motion (5-15 mm) was most prominent in the blood phase in 63% and 44% of the stress and rest studies, respectively. This motion was observed with frequencies of 75% in the septal and inferior directions for stress and 44% in the septal direction for rest. Images with blood phase isolated motion had mean global MBF and MFR errors of 2%-5%. Isolating blood phase motion in the inferior direction resulted in mean MBF and MFR errors of 29%-44% in the RCA territory. Flow errors due to tissue phase isolated motion were within 1%. CONCLUSIONS: Patient motion was most prevalent in the blood phase and MBF and MFR errors increased most substantially with motion in the inferior direction. Motion correction focused on these motions is needed to reduce MBF and MFR errors. PMID- 29572595 TI - An improved indirect ELISA for specific detection of antibodies against classical swine fever virus based on structurally designed E2 protein expressed in suspension mammalian cells. AB - Classical swine fever (CSF), which is caused by classical swine fever virus (CSFV), is a highly contagious disease of pigs. CSFV is genetically and serologically related to bovine viral diarrhea virus (BVDV), a ruminant pestivirus. However, currently available ELISAs based on the full-length E2 protein of CSFV cannot discriminate anti-CSFV from anti-BVDV antibodies. In this study, a truncated CSFV E2 protein (amino acids 690 to 879) covering antigenic domains B/C/D/A (E2B/C/D/A) was designed based on homologous modeling according to the crystal structure of the BVDV E2 protein. The E2B/C/D/A protein was expressed in CHO cells adapted to serum-free suspension culture, and an indirect ELISA (iELISA) was established based on the recombinant protein. No serological cross-reaction was observed for anti-BVDV sera in the iELISA. When testing 282 swine serum samples, the iELISA displayed a high sensitivity (119/127, 93.7%) and specificity (143/155, 92.3%), with an agreement of 92.9% (262/282) and 92.2% (260/282) with virus neutralization test and the IDEXX CSFV blocking ELISA, respectively. Taken together, the newly developed iELISA is highly specific and sensitive and able to differentiate anti-CSFV from anti-BVDV antibodies. PMID- 29572596 TI - Smacoviridae: a new family of animal-associated single-stranded DNA viruses. AB - Smacoviruses have small (~2.3-2.9 kb), circular single-stranded DNA genomes encoding rolling circle replication-associated proteins (Rep) and unique capsid proteins. Although smacoviruses are prevalent in faecal matter of various vertebrates, including humans, none of these viruses have been cultured thus far. Smacoviruses display ~45% genome-wide sequence diversity, which is very similar to that found within other families of circular Rep-encoding single-stranded (CRESS) DNA viruses, including members of the families Geminiviridae (46% diversity) and Genomoviridae (47% diversity). Here, we announce the creation of a new family Smacoviridae and describe a sequence-based taxonomic framework which was used to classify 83 smacovirus genomes into 43 species within six new genera, Bovismacovirus (n=3), Cosmacovirus (n=1), Dragsmacovirus (n=1), Drosmacovirus (n=3), Huchismacovirus (n=7), and Porprismacovirus (n=28). As in the case of genomoviruses, the species demarcation is based on the genome-wide pairwise identity, whereas genera are established based on the Rep amino acid sequence identity coupled with strong phylogenetic support. A similar sequence-based taxonomic framework should guide the classification of an astonishing diversity of other uncultured and currently unclassified CRESS DNA viruses discovered by metagenomic approaches.

PMID- 29572598 TI - Determination of Quality Criteria that Allow Differentiation Between Honey Adulterated with Sugar and Pure Honey. AB - This study used various parameters of honey to develop a potentially more robust approach to the detection of adulterated honey. For this purpose, 25 multifloral, natural honey samples and 20 samples of adulterated honey produced by bees that had been fed supplementary sucrose syrup were analysed. The mean total phenolic content of the natural honeys was considerably higher than in the adulterated honeys at 157 +/- 13 and 35.2 +/- 7.3 mg GAE/100 g, respectively. Similarly, considerable variation was determined between natural and adulterated honeys in terms of total flavonoids (3.3 +/- 0.3 and 2.1 +/- 0.4 mg QE/100 g, respectively), antiradical activity (87.9 +/- 12 and 163 +/- 11 mg/mL, respectively) and proline content (202 +/- 26 and 71.1 +/- 21.6 mg/kg, respectively.) The potassium, phosphorus, calcium and magnesium contents of natural honeys were also higher than in adulterated honeys (P < 0.01). In conclusion, the determination of the proline level, phenolic content, antioxidant activity and mineral profile may collectively provide a more holistic method approach to the differentiation of natural and adulterated honey, and also for comparing their food values. PMID- 29572599 TI - Laparoscopic fenestration for a huge symptomatic splenic cyst in a patient with Gaucher's disease. AB - A 34-year-old woman visited our hospital for treatment of a huge splenic cyst with epigastric pain. She had been diagnosed with Gaucher's disease (Type 1) at 3 years of age and had been receiving enzyme replacement therapy (ERT) from 15 years of age. Abdominal MRI showed a low-intensity area, 30 cm in diameter, with a well-defined border on T1-weighted images. The patient underwent laparoscopic fenestration of the huge splenic cyst for relief of worsening epigastric pain caused by the cyst. The cyst contained 2,500 ml of brownish-red fluid. The patient recovered satisfactorily and was discharged on postoperative day 11. Gaucher's disease is an extremely rare metabolic disease; only about 6,000 patients are registered in the International Collaborative Gaucher Group Gaucher Registry. An extremely rare case of a huge symptomatic splenic cyst treated by laparoscopic fenestration in a patient with Gaucher's disease is described. PMID- 29572600 TI - Decreased Cerebral Blood Flow in Mesial Thalamus and Precuneus/PCC during Midazolam Induced Sedation Assessed with ASL. AB - While some previous work suggests that midazolam-induced light sedation results from the functional disconnection within resting state network, little is known about the underlying alterations of cerebral blood flow (CBF) associated with its effects. A randomized, double-blind, within-subject, cross-over design was adopted, while 12 healthy young volunteers were scanned with arterial spin labeling (ASL) perfusion MRI both before and after an injection of either saline or midazolam. The contrast of MRI signal before and after midazolam administration revealed the CBF decrease in the bilateral mesial thalamus and precuneus/posterior cingulate cortex (PCC). These effects were confirmed after controlling for any effect of injection as well as head motions. These findings provide new evidences that midazolam-induced light sedation is related to the disruption of cortical functional integration, and have new implications to the neural basis of consciousness. PMID- 29572601 TI - Multi-Modality Cascaded Convolutional Neural Networks for Alzheimer's Disease Diagnosis. AB - Accurate and early diagnosis of Alzheimer's disease (AD) plays important role for patient care and development of future treatment. Structural and functional neuroimages, such as magnetic resonance images (MRI) and positron emission tomography (PET), are providing powerful imaging modalities to help understand the anatomical and functional neural changes related to AD. In recent years, machine learning methods have been widely studied on analysis of multi-modality neuroimages for quantitative evaluation and computer-aided-diagnosis (CAD) of AD. Most existing methods extract the hand-craft imaging features after image preprocessing such as registration and segmentation, and then train a classifier to distinguish AD subjects from other groups. This paper proposes to construct cascaded convolutional neural networks (CNNs) to learn the multi-level and multimodal features of MRI and PET brain images for AD classification. First, multiple deep 3D-CNNs are constructed on different local image patches to transform the local brain image into more compact high-level features. Then, an upper high-level 2D-CNN followed by softmax layer is cascaded to ensemble the high-level features learned from the multi-modality and generate the latent multimodal correlation features of the corresponding image patches for classification task. Finally, these learned features are combined by a fully connected layer followed by softmax layer for AD classification. The proposed method can automatically learn the generic multi-level and multimodal features from multiple imaging modalities for classification, which are robust to the scale and rotation variations to some extent. No image segmentation and rigid registration are required in pre-processing the brain images. Our method is evaluated on the baseline MRI and PET images of 397 subjects including 93 AD patients, 204 mild cognitive impairment (MCI, 76 pMCI +128 sMCI) and 100 normal controls (NC) from Alzheimer's Disease Neuroimaging Initiative (ADNI) database. Experimental results show that the proposed method achieves an accuracy of 93.26% for classification of AD vs. NC and 82.95% for classification pMCI vs. NC, demonstrating the promising classification performance. PMID- 29572602 TI - Survivorship care plans: are randomized controlled trials assessing outcomes that are relevant to stakeholders? AB - PURPOSE: The purpose of this study was to compare outcomes assessed in extant randomized controlled trials (RCTs) to outcomes that stakeholders expect from survivorship care plans (SCPs). To facilitate the transition from active treatment to follow-up care for the 15.5 million US cancer survivors, many organizations require SCP use. However, results of several RCTs of SCPs' effectiveness have been null, possibly because they have evaluated outcomes on which SCPs should be expected to have limited influence. Stakeholders (e.g., survivors, oncologists) may expect outcomes that differ from RCTs' outcomes. METHODS: We identified RCTs' outcomes using a PubMed literature review. We identified outcomes that stakeholders expect from SCPs using semistructured interviews with stakeholders in three healthcare systems in the USA and Canada. Finally, we mapped RCTs' outcomes onto stakeholder-identified outcomes. RESULTS: RCT outcomes did not fully address outcomes that stakeholders expected from SCPs, and RCTs assessed outcomes that stakeholders did not expect from SCPs. RCTs often assessed outcomes only from survivors' perspectives. CONCLUSIONS: RCTs of SCPs' effectiveness have not assessed outcomes that stakeholders expect. To better understand SCPs' effectiveness, future RCTs should assess outcomes of SCP use that are relevant from the perspective of multiple stakeholders. IMPLICATIONS FOR CANCER SURVIVORS: SCPs' effectiveness may be optimized when used with an eye toward outcomes that stakeholders expect from SCPs. For survivors, this means using SCPs as a map to guide them with respect to what kind of follow-up care they should seek, when they should seek it, and from whom they should seek it. PMID- 29572603 TI - Risk factor analysis of recanalization and retreatment for patients with endovascular treatment of internal carotid artery bifurcation aneurysms. AB - PURPOSE: Only a few reports of internal carotid artery (ICA) bifurcation aneurysms using the endovascular technique have been published in the current literature. The purpose of this study was to assess how multiple risk factors including angioarchitectural features of ICA bifurcation characteristics may have influenced aneurysmal rupture, recanalization, and retreatment. METHODS: Fifty one patients with 52 ICA bifurcation aneurysms treated with endovascular coiling between July 2003 and July 2015 were retrospectively analyzed. The patients' clinical records, endovascular reports, and clinical and angiographic outcomes were reviewed. We also evaluated risk factors for recanalization and retreatment, including the angioarchitectural anatomy. RESULTS: The clinical outcomes were observed to be satisfactory in 49 patients (96.0%) and unfavorable in 2 patients (4.0%). The risk factor for aneurysmal rupture was young age (P = 0.024). Symptomatic complications due to thromboembolism occurred in 1.9% of cases; no patients suffered a fatal complication. Eleven of 52 ICA bifurcation aneurysms (21.2%) were recanalized within an average of 54.3 +/- 33.5 months of follow-up. Among the aneurysms, 4 (7.7%) underwent recoiling. Multivariate analysis showed that ruptured aneurysms (P = 0.006) and a lower packing density (P = 0.048) were risk factors for recanalization. A lower packing density was the only risk factor for retreatment (P = 0.019). CONCLUSION: Endovascular treatment of ICA bifurcation aneurysms is considered safe and acceptable. This study showed that the ICA bifurcation aneurysms ruptured more frequently at a younger age. A higher packing density has been shown to reduce major recanalization and retreatment. PMID- 29572604 TI - Intrathecal gadolinium-enhanced MR cisternography in patients with otorhinorrhea: 10-year experience of a tertiary referral center. AB - PURPOSE: Despite a considerable amount of literature that has been published about the use of intrathecal gadolinium-enhanced MR cisternography (IGE-MRC), there is still relatively lack of evidence as to its long-term effects. Our purpose in this study was twofold: firstly, to assess the long-term safety of the IGE-MRC; secondly, to evaluate the diagnostic performance of IGE-MRC for detecting cerebrospinal fluid (CSF) leak in otorhinorrhea patients. METHODS: We retrospectively reviewed our imaging and clinical database for the patients admitted to our department for the evaluation of their otorhinorrhea between 2008 and 2017. Two radiologists evaluated the imaging studies independently. Consensus data was used in the analysis. Medical record review and phone call were used for the long-term follow-up. RESULTS: The retrospective review yielded 166 patients. Rhinorrhea was present in 150 (90.4%) patients and otorrhea in 16 (9.6%) patients. Overall, 67 patients (40.5% of all patients) underwent operation for repair of the CSF leak site. Beta-transferrin test was available and positive in 57 (34.3%) patients. Overall sensitivity of IGE-MRC and paranasal high-resolution CT (HRCT) was 89.3 and 72%, respectively. Within the first 24 h after the procedure, none of the patients experienced a significant complication or adverse reaction. Ninety-nine patients (59.6%) had medical record and telephone follow up. The mean follow-up duration with call was 37.1 months. Three (3%) patients complained about severe headache 3-4 weeks after the procedure. CONCLUSIONS: IGE MRC is a minimally invasive and highly sensitive imaging technique. No adverse side effect during our long-term follow-up might strengthen and support the safety of IGE-MRC. PMID- 29572605 TI - Inflammatory Bowel Disease Across the Age Continuum: Similarity and Disparity. AB - OBJECTIVES: To identify similarities and differences between the pediatric-onset and adult-onset Inflammatory Bowel Disease (IBD) based cohorts and further characterize the pediatric cohort. METHODS: A retrospective analysis of pediatric patients attending the tertiary referral care gastroenterology center from 2004 to 2016 was conducted. All the patients were clinically evaluated, investigated and followed up at the centre. RESULTS: Sixty five patients with pediatric IBD were compared with 216 patients with adult-onset IBD. The Ulcerative colitis: Crohn's disease (UC:CD) ratio was higher in adult-onset population (2.29:1 vs. 1.7:1). Predominant symptoms in pediatric UC were diarrhea and passage of blood in stools; whereas those in pediatric CD were abdominal pain and failure to gain weight. Ulcerative proctitis was less common (2.4% vs. 18.8%; p = 0.009) and an extensive disease (pancolitis) was more common in the pediatric population (73.1% vs. 30.2%; p < 0.00001). Adult CD had higher L3 (33.3% vs. 46.1%; p = 0.28) disease; whereas in pediatric CD, L1 disease (37.5% vs. 32.3%; p = 0.65) was predominant. There was no difference with respect to penetrating and stricturing complications of CD in adults vs. children (20.8% vs. 23.1%; p = 0.974). 5-ASA agents were used more commonly in the pediatric IBD population (96.9% vs. 79.9%; p = 0.0034) as compared to adults whereas corticosteroids (87.5% vs. 76.9%; p = 0.28) and infliximab (25% vs. 9.2%; p = 0.054) were used more frequently in the pediatric CD subgroup as compared to adult CD subgroup. CONCLUSIONS: IBD has significant disease heterogeneity according to the age of onset. Pediatric IBD has distinctive features that set it apart from adult-onset IBD.

AB - The components of the hepatic vascular system (hepatic arteries, portal and hepatic veins, sinusoids, and lymphatics) can be damaged by various types of injury. Each of the resulting conditions is rare, which has limited knowledge and awareness. In the last two decades, international collaborations have allowed to reach critical masses of data, which has driven significant progresses in understanding and management of vascular disorders of the liver. The present paper discusses definitions, denominations, and diagnosis of such vascular disorders with the exception of those affecting hepatic arteries. Evolving pathogenic or pathophysiologic views relevant to the clinical aspects are also overviewed. PMID- 29572607 TI - Invasive forest pathogens in Europe: Cross-country variation in public awareness but consistency in policy acceptability. AB - Political action can reduce introductions of diseases caused by invasive forest pathogens (IPs) and public support is important for effective prevention. The public's awareness of IP problems and the acceptability of policies aiming to combat these pathogens were surveyed in nine European countries (N = 3469). Although awareness of specific diseases (e.g., ash dieback) varied, problem awareness and policy acceptability were similar across countries. The public was positive towards policies for informational measures and stricter standards for plant production, but less positive towards restricting public access to protected areas. Multilevel models, including individual and country level variables, revealed that media exposure was positively associated with awareness of IP problems, and strengthened the link between problem awareness and policy acceptability. Results suggest that learning about IPs through the media and recognizing the associated problems increase policy acceptability. Overall, the study elaborates on the anthropogenic dimension of diseases caused by IPs. PMID- 29572608 TI - Comment on "Safety of Human Papillomavirus Vaccines: An Updated Review". PMID- 29572609 TI - Comment on: "Safety of Human Papillomavirus Vaccines: An Updated Review". PMID- 29572610 TI - The application of the palliative prognostic index in predicting the life expectancy of patients in palliative care: a systematic review and meta-analysis. AB - BACKGROUND: The palliative prognostic index (PPI) is a commonly used tool to predict the life expectancy in palliative care patients. However, there is no universal cutoff, and the accuracy of different cutoffs varies. Therefore, we conducted this meta-analysis to explore the validity and accuracy of different PPI scores for different survival time in palliative care setting. METHODS: PubMed, Embase, Cochrane, Scopus and Chinese CNKI databases were searched to identify studies using the PPI as a prognostic tool to predict survival time in palliative care. We calculated pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs), and subgroup analyses were also conducted by different cutoffs. After extracting data, we estimated the pooled sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: We identified 15 studies with 7455 assessments. Seven of these studies were synthesized for a combined HR. The pooled HR was 1.94 (95% CI 1.54-2.44) when cutoffs were 2 and 4, and 2.34 (95% CI 1.50-3.66) when cutoffs were 4 and 6. Of all the studies, 13 studies reported their accuracy, of which four studies were assessed by meta-analysis. The sensitivity of the PPI for 3-week survival ranged from 51 to 92% and specificity ranged from 60.0 to 94.0%, respectively. The sensitivity and specificity of the PPI for 6-week survival were from 46.0 to 89.1% and from 51.7 to 84.4%, respectively. The pooled sensitivity and specificity of the PPI for 3-week survival were 68% (6 as cutoff) and 76% (6 as cutoff), respectively. As for 6-week survival prediction, the pooled sensitivity and specificity were 68% (4 as cutoff) and 82% (4 as cutoff), respectively. CONCLUSION: The PPI is a useful prognosticator of life expectancy of patients in palliative care, especially for patients with short survival time. However, there were no universal cutoff, and the predicted life span varies. Our data eliminated that using 4 and 6 as cutoffs can better predict the patients' survival time for 3 or 6 weeks. Due to small number of studies and poor qualities of them, result may alter as more studies with better quality are enrolled in the future. PMID- 29572611 TI - Usefulness of a pleuroperitoneal shunt for treatment of refractory pleural effusion in a patient receiving maintenance hemodialysis. AB - Refractory pleural effusion can be a life-threatening complication in patients receiving maintenance hemodialysis. We report successful treatment of refractory pleural effusion using a Denver(r) pleuroperitoneal shunt in one such patient. A 54-year-old Japanese man, who had previously undergone left nephrectomy, was admitted urgently to our department because of a high C-reactive protein (CRP) level, right pleural effusion, and right renal abscess. Because antibiotics proved ineffective and his general state was deteriorating, he underwent emergency insertion of a thoracic drainage tube and nephrectomy, and hemodialysis was started. Although his general state improved slowly thereafter, the pleural effusion, which was unilateral and transudative, remained refractory and therefore he needed to be on oxygenation. To control the massive pleural effusion, a pleuroperitoneal shunt was inserted. Thereafter, his respiratory condition became stable without oxygenation and he was discharged. His general condition has since been well. Although pleural effusion is a common complication of maintenance hemodialysis, few reports have documented the use of pleuroperitoneal shunt to control refractory pleural effusion. Pleuroperitoneal shunt has been advocated as an effective and low-morbidity treatment for refractory pleural effusion, and its use for some patients with recurrent pleural effusion has also been reported, without any severe complications. In the present case, pleuroperitoneal shunt improved the patient's quality of life sufficiently to allow him to be discharged home without oxygenation. Pleuroperitoneal shunt should be considered a useful treatment option for hemodialysis patients with refractory pleural effusion. PMID- 29572612 TI - Substrate selection of adenylation domains for nonribosomal peptide synthetase (NRPS) in bacillamide C biosynthesis by marine Bacillus atrophaeus C89. AB - Nonribosomal peptide synthetases (NRPSs) are multi-modular enzymes involved in the biosynthesis of natural products. Bacillamide C was synthesized by Bacillus atrophaeus C89. A nonribosomal peptide synthetase (NRPS) cluster found in the genome of B. atrophaeus C89 was hypothesized to be responsible for the biosynthesis of bacillamide C using alanine and cysteine as substrates. Here, the structure analysis of adenylation domains based on homologous proteins with known crystal structures indicated locations of the substrate-binding pockets. Molecular docking suggested alanine and cysteine as the potential substrates for the two adenylation domains in the NRPS cluster. Furthermore, biochemical characterization of the purified recombinant adenylation domains proved that alanine and cysteine were the optimum substrates for the two adenylation domains. The results provided the in vitro evidence for the hypothesis that the two adenylation domains in the NRPS of B. atrophaeus C89 preferentially select alanine and cysteine, respectively, as a substrate to synthesize bacillamide C. Furthermore, this study on substrates selectivity of adenylation domains provided basis for rational design of bacillamide analogs. PMID- 29572613 TI - Response of gastrointestinal melatonin, antioxidants, and digestive enzymes to altered feeding conditions in carp (Catla catla). AB - The purpose of present study was to ascertain whether the response of gastrointestinal (gut) melatonin to altered feeding conditions was related to the levels of different antioxidants and digestive enzymes in the same gut tissues of a sub-tropical carp (Catla catla). Accordingly, the fish were subjected to food deprivation for 4 or 8 days and separately to re-feeding for 4 or 8 or 12 days after deprivation of food for 8 days, and their gut tissue homogenates were used to measure the levels of melatonin, both enzymatic [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST)] and non-enzymatic [reduced glutathione (GSH)] antioxidants, as well as different digestive enzymes (alpha-amylase, cellulase, protease, and lipase). Notably, the gut levels of melatonin, SOD, CAT, GPx, and GST underwent gradual increase with the progress of food deprivation, but a sudden fall after restoration of food supply for 4 days and a rise thereafter. Conversely, the activity of all the digestive enzymes significantly decreased after deprivation of food, but started increasing when food supply was reinforced. Gut melatonin concentrations by showing a positive correlation with the titers of different antioxidants (in both food-deprived and re-fed fish groups) and a negative (in food-deprived fish) or a positive (in re-fed fish) correlation with the activity of each digestive enzyme underlined possible physiological interplay between them. Collectively, our findings lend support to the hypothesis that gut melatonin response to altered feeding conditions in carp might be associated with the oxidative status as well as the digestive functions of the gastrointestinal tissues itself. PMID- 29572614 TI - A case of ruptured aneurysm of coronary-pulmonary artery fistula diagnosed after emergency thoracotomy. AB - BACKGROUND: Coronary fistulae are occasionally detected using echocardiography or coronary angiography. We report a patient with cardiac tamponade because of a ruptured aneurysm of a coronary artery fistula. CASE PRESENTATION: A 60-year-old man was referred to our hospital with sudden onset of chest pain and unconsciousness. He was initially diagnosed with cardiac tamponade for type A acute aortic dissection, and an emergency operation was performed. A large amount of bleeding was seen in the pericardium, but aortic dissection around the arch was not observed. Instead, a ruptured aneurysm of a coronary-pulmonary fistula was identified on the pulmonary artery root. The aneurysm was resected, and the fistula was closed by ligation. The patient's postoperative progress was good, and he was discharged on postoperative day 12 without any abnormalities on the coronary arteriogram. CONCLUSIONS: Preoperative diagnosis of the rupture of the small coronary artery aneurysm is difficult in such an emergency case, and this possibility should be considered in differential diagnosis when the CT image does not show typical aortic dissection. PMID- 29572616 TI - Tropheryma whipplei Infection (Whipple Disease) in the USA. AB - BACKGROUND: Whipple disease (WD) is an infection caused by the bacterium Tropheryma whipplei (TW). Few cases have been reported in the USA. AIMS: To report on the demographics, clinical manifestations, diagnostic findings, treatment, and outcomes of TW infection. METHODS: Cases of TW infection diagnosed from 1995 to 2010 were identified in three US referral centers and from 1995 to 2015 in one. Definite classic WD was defined by positive periodic acid-Schiff (PAS) staining and probable WD by specific positive TW polymerase chain reaction (PCR) of intestinal specimens. Localized infections were defined by a positive TW PCR result from samples of other tissues/body fluids. RESULTS: Among the 33 cases of TW infections, 27 (82%) were male. Median age at diagnosis was 53 years (range 11-75). Diagnosis was supported by a positive TW PCR in 29 (88%) and/or a positive PAS in 16 (48%) patients. Classic WD was the most frequent presentation (n = 18, 55%), with 14 definite and 4 probable cases. Localized infections (n = 15, 45%) affected the central nervous system (n = 7), joints (n = 4), heart (n = 2), eye (n = 1), and skeletal muscle (n = 1). Blood PCR was negative in 9 of 17 (53%) cases at diagnosis. Ceftriaxone intravenously followed by trimethoprim and sulfamethoxazole orally was the most common regimen (n = 23, 70%). Antibiotic therapy resulted in clinical response in 24 (73%). CONCLUSIONS: TW infection can present as intestinal or localized disease. Negative small bowel PAS and PCR do not exclude the diagnosis of TW infection, and blood PCR is insensitive for active infection. PMID- 29572617 TI - Robotic Autotransplantation and Management of Post-transplant Anastomotic Strictures: the Future Is Here. AB - PURPOSE OF REVIEW: We set out to review the current published experience with robotic autotransplantation. Although the experience to date is limited, this surgery appears to be safe and technically feasible. We also examined the use of the robotic surgical platform for the management of post-transplant uretero vesical anastomotic strictures. RECENT FINDINGS: To date, only four reported cases of robotic autotransplantation have been described with two being performed completely intra-corporeally. An intra-corporeal approach is feasible for benign conditions, while malignant masses should be inspected and dissected extra corporeally. Ureteric strictures after renal transplantation are common. To date, the experience with robotic surgical management is limited but has also been shown to be safe and feasible. While robotic autotransplantation is still in its infancy, it is feasible and appears to be safe. Renal allograft function and surgical outcomes are favorable and provide patients the option to have a historically more morbid surgery performed with a minimally invasive approach. PMID- 29572619 TI - The Effect of Cognitive-Emotional Training on Post-traumatic Growth in Women with Breast Cancer in Middle East. AB - Overcoming distresses and negative consequences of serious crises such as cancers can lead to perception of positive changes in the patients. It is necessary to design and test the psychological interventions that can improve post-traumatic growth. The objective of this study was to determine the effect of cognitive emotional training on post-traumatic growth in women with breast cancer referred to the department of chemotherapy. This is a quasi-experimental study and it was performed on 85 patients with breast cancer who referred to an educational hospital in southeastern of Iran in 2017. The eligible patients were selected through convenience method sampling among the patients and they randomly allocated into intervention and control groups. The intervention group received five sessions of emotional-cognitive training in two sessions per week. Each session lasted 60-90 min. The posttest data were collected by post-traumatic growth inventory (PTGI) 20 weeks after the end of the last intervention session. Collected data were analyzed by SPSS software version 21.00 using independent t test, paired t test, and Chi-square tests for demographic analysis. The results indicated that there is no significant difference in both groups in terms of individual variables such as age, marriage, duration of disease, and degree progression of cancer. Although the mean of PTG scores in posttest and the mean of variations in the PTG scores in the intervention group were 77.48 +/- 11.18 and 25.81 +/- 12.24, respectively, and it was significantly higher than the control group, 53.95 +/- 14.86 and 7.69 +/- 9, respectively (mean scores of PTG: p < .0001; mean changes of PTG: p < .001). According to the results of this study, cognitive-behavioral intervention had a positive and significant effect on post-traumatic growth in women with breast cancer. If intervention is found to be effective, cognitive and emotional strategies of such interventions could be integrated into daily clinical practice as a way to promote PTG in women who are being treated for breast cancer. PMID- 29572618 TI - The Use of Statins in Patients With Chronic Liver Disease and Cirrhosis. AB - PURPOSE OF REVIEW: Statins are drugs developed to treat hypercholesterolemia. Its use in patients with liver disease has been limited because one of its potential and most feared side effects is hepatotoxicity. However, there is robust evidence that supports the safety of statins in this population in the absence of severe liver dysfunction. In this review, we will summarize the efficacy and safety of statins in cirrhosis. RECENT FINDINGS: Statins are effective in the treatment of dyslipidemia in patients with liver disease, because of their pleiotropic properties. These properties are independent of their effect on cholesterol levels, such as improving endothelial dysfunction or having antioxidant, antifibrotic, anti-inflammatory, antiproliferative, antiangiogenic, proapoptotic, or immunomodulation properties. Statins have been studied in other areas such as in treatment of portal hypertension, prevention of hepatocellular carcinoma, and/or protection against ischemia/reperfusion injury. Approved indications for statins in patients with cirrhosis are those of the general population, including dyslipidemia and increased cardiovascular risk. Compensated cirrhosis is not a contraindication. In patients with decompensated cirrhosis, statins should be prescribed with extreme caution at low doses, and with frequent monitoring of creatinine phosphokinase levels in order to detect adverse events in a timely fashion. PMID- 29572615 TI - Precision Medicine for CRC Patients in the Veteran Population: State-of-the-Art, Challenges and Research Directions. AB - Colorectal cancer (CRC) accounts for ~9% of all cancers in the Veteran population, a fact which has focused a great deal of the attention of the VA's research and development efforts. A field-based meeting of CRC experts was convened to discuss both challenges and opportunities in precision medicine for CRC. This group, designated as the VA Colorectal Cancer Cell-genomics Consortium (VA4C), discussed advances in CRC biology, biomarkers, and imaging for early detection and prevention. There was also a discussion of precision treatment involving fluorescence-guided surgery, targeted chemotherapies and immunotherapies, and personalized cancer treatment approaches. The overarching goal was to identify modalities that might ultimately lead to personalized cancer diagnosis and treatment. This review summarizes the findings of this VA field based meeting, in which much of the current knowledge on CRC prescreening and treatment was discussed. It was concluded that there is a need and an opportunity to identify new targets for both the prevention of CRC and the development of effective therapies for advanced disease. Also, developing methods integrating genomic testing with tumoroid-based clinical drug response might lead to more accurate diagnosis and prognostication and more effective personalized treatment of CRC. PMID- 29572620 TI - Groundwater fluoride contamination, probable release, and containment mechanisms: a review on Indian context. AB - Fluoride contamination in the groundwater has got great attention in last few decades due to their toxicity, persistent capacity and accumulation in human bodies. There are several sources of fluoride in the environment and different pathways to enter in the drinking water resources, which is responsible for potential effect on human health. Presence of high concentration of fluoride ion in groundwater is a major issue and it makes the water unsuitable for drinking purpose. Availability of fluoride in groundwater indicates various geochemical processes and subsurface contamination of a particular area. Fluoride-bearing aquifers, geological factors, rate of weathering, ion-exchange reaction, residence time and leaching of subsurface contaminants are major responsible factors for availability of fluoride in groundwater. In India, several studies have reported that the groundwater of several states are contaminated with high fluoride. The undesirable level of fluoride in groundwater is one of the most natural groundwater quality problem, which affects large portion of arid and semiarid regions of India. Rajasthan, Andhra Pradesh, Telangana, Tamil Nadu, Gujarat, and West Bengal are the relatively high-fluoride-contaminated states in India. Chronic ingestion of high doses of fluoride-rich water leads to fluorosis on human and animal. Over 66 million Indian populations are at risk due to excess fluoride-contaminated water. Therefore, groundwater contamination subject to undesirable level of fluoride needs urgent attention to understand the role of geochemistry, hydrogeology and climatic factors along with anthropogenic inputs in fluoride pollution. PMID- 29572621 TI - Blood-brain barrier leakage in relation to white matter hyperintensity volume and cognition in small vessel disease and normal aging. AB - Blood-brain barrier (BBB) leakage increases with age and is involved in the pathophysiology of cerebral small vessel disease (cSVD). We examined the relationship between BBB leakage and white matter hyperintensity (WMH) volume and cognition, in cSVD patients and healthy controls. Seventy-seven patients with clinically overt cSVD and thirty-nine age matched healthy controls underwent dynamic contract-enhanced and structural brain MRI and neuropsychological assessment. We quantified BBB leakage volume and rate in normal appearing white matter (NAWM), WMH and cortical grey matter (CGM). Larger leakage volume and lower leakage rate in WMH were associated with larger WMH volume in cSVD but not in controls. Higher leakage rate in NAWM was associated with lower scores on executive function and information processing speed in healthy controls, whereas no relation with cognition was found in cSVD patients. Our findings support the involvement of BBB leakage in cSVD and aging. They also suggest that the mechanism of cognitive dysfunction in cSVD is more complex and multifactorial in cSVD compared with normal aging. PMID- 29572622 TI - Weight loss in men in late life and bone strength and microarchitecture: a prospective study. AB - : Weight loss in men in late life was associated with lower bone strength. In contrast, weight gain was not associated with a commensurate increase in bone strength. Future studies should measure concurrent changes in weight and parameters of bone strength and microarchitecture and evaluate potential causal pathways underlying these associations. INTRODUCTION: Our aim was to determine associations of weight loss with bone strength and microarchitecture. METHODS: We used data from 1723 community-dwelling men (mean age 84.5 years) who attended the MrOS study Year (Y) 14 exam and had high-resolution peripheral quantitative computed tomography (HR-pQCT) scans at >= 1 skeletal sites (distal tibia, distal radius, or diaphyseal tibia). Weight change from Y7 to Y14 exams (mean 7.3 years between exams) was classified as moderate weight loss (loss >= 10%), mild weight loss (loss 5 to < 10%), stable weight (< 5% change), or weight gain (gain >= 5%). Mean HR-pQCT parameters (95%CI) were calculated by weight change category using linear regression models adjusted for age, race, site, health status, body mass index, limb length, and physical activity. The primary outcome measure was estimated failure load. RESULTS: There was a nonlinear association of weight change with failure load at each skeletal site with different associations for weight loss vs. weight gain (p < 0.03). Failure load and total bone mineral density (BMD) at distal sites were lower with greater weight loss with 7.0-7.6% lower failure loads and 4.3-5.8% lower BMDs among men with moderate weight loss compared to those with stable weight (p < 0.01, both comparisons). Cortical, but not trabecular, BMDs at distal sites were lower with greater weight loss. Greater weight loss was associated with lower cortical thickness at all three skeletal sites. CONCLUSION: Weight loss in men in late life is associated with lower peripheral bone strength and total BMD with global measures reflecting cortical but not trabecular parameters. PMID- 29572623 TI - Fatal methemoglobinemia complicating alkaptonuria (ochronosis): a rare presentation. AB - A 61-year-old female died in hospital with multiple organ failure 4 weeks following presentation with acute kidney injury, hemolytic anemia and methemoglobinemia. At autopsy, brown to black discoloration of cartilages was observed. Histology revealed brown pigmentation of the hyaline cartilage, with focal full-thickness erosion of the articular hyaline cartilage, characteristic of alkaptonuria (ochronosis). Although alkaptonuria is rarely fatal, this case illustrates a rare acute fatal complication. Accumulation of circulating homgentisic acid secondary to acute derangement of renal function is believed to have overwhelmed the endogenous antioxidant processes, resulting in hemolysis and methemoglobinemia, which were refractory to treatment. Small numbers of cases have previously been reported in the literature in patients known to suffer with the disease, all of which were preceded by acute kidney injury. Whilst the clinical diagnosis of alkaptonuria may be challenging, the autopsy findings of this rare condition are striking and this case illustrates the utility of the autopsy, albeit retrospectively, in arriving at a diagnosis. To our knowledge this is the first reported case where previously undiagnosed alkaptonuria has presented with methemoglobinemia. PMID- 29572624 TI - Significance and Management of Isolated Hepatitis B Core Antibody (Anti-HBc) in HIV and HCV: Strategies in the DAA Era. AB - PURPOSE OF REVIEW: The purpose of this review is to summarize the prevalence and clinical implications of the isolated anti-HBc serologic profile in HIV-infected individuals. We highlight the rare but important issue of HBV reactivation in the setting of HCV therapy and describe an approach to management. RECENT FINDINGS: The isolated anti-HBc pattern, a profile that most often indicates past exposure to HBV with waning anti-HBs immunity, is found commonly in HIV-infected individuals, particularly those with HCV. Some large cohort studies demonstrate an association with advanced liver disease, while others do not. Conversely, meta analyses have found an association between occult HBV infection (a component of the isolated anti-HBc pattern) and advanced liver disease and hepatocellular carcinoma in HIV-uninfected individuals. In HIV-uninfected individuals with anti HBc positivity, HBV reactivation has been reported in patients receiving HCV therapy. This phenomenon is likely the result of disinhibition of HBV with HCV eradication. In HIV-infected patients, the long-term liver outcomes associated with the isolated anti-HBc pattern remain to be fully elucidated, supporting the need for large cohort studies with longitudinal follow-up. HBV reactivation during HCV DAA therapy has been well-described in HIV-uninfected cohorts and can inform algorithms for the screening and management of the isolated anti-HBc pattern in this population. PMID- 29572626 TI - Is visual activation associated with changes in cerebral high-energy phosphate levels? AB - Phosphorus magnetic resonance spectroscopy (31P MRS) has been employed before to assess phosphocreatine (PCr) and other high-energy phosphates in the visual cortex during visual stimulation with inconsistent results. We performed functional 31P MRS imaging in the visual cortex and control regions during a visual stimulation paradigm at an unprecedented sensitivity, exploiting a dedicated RF coil design at a 7 T MR system. Visual stimulation in a 3 min 24 s on-off paradigm in eight young healthy adults generated a clear BOLD effect with traditional 1H functional MRI in the visual cortex (average z score 9.9 +/- 0.2). However, no significant event-related changes in any of the 31P metabolite concentrations, linewidths (7.9 +/- 1.8 vs 7.8 +/- 1.9 Hz) or tissue pH (7.07 +/- 0.13 vs 7.06 +/- 0.07) were detectable. Overall, our study of 31P MRSI in 15 cm3 voxels had a detection threshold for changes in PCr, Pi and gamma-ATP between stimulation and rest of 5, 17 and 10%, respectively. In individual subjects, the mean coefficients of variance for PCr and Pi levels of control voxels were 6 +/- 3 and 19 +/- 8% (three time point average of 3 min 24 s). Altogether this indicates that energy supply for neuronal activation at this temporal resolution does not drain global PCr resources. PMID- 29572627 TI - Functional impairment and risk of mortality in patients on chronic hemodialysis: results of the Lazio Dialysis Registry. AB - BACKGROUND: Functional impairment is associated with adverse outcomes in older people, as well as in patients on chronic hemodialysis. The aim of this study was to evaluate if functional impairment represents a risk factor for reduced survival in patients on chronic hemodialysis. METHODS: All incident chronic hemodialysis patients of Lazio, a large region of central Italy, registered in the Dialysis and Transplant Lazio Region Registry (DTLRR) in the period 2008-2013 were considered eligible. Inclusion criteria were: age > 18 years, resident in Lazio, still doing dialysis after 90 days from incidence date, doing hemodialysis or hemodiafiltration treatment for > 9 h/week. Patients were stratified into three classes of functional activity: total autonomy, autonomy in some activities, and not self-sufficient. Functional activity was assessed for each patient by the referring physician for the DTLRR from the ~ 90 hemodialysis units of the Lazio region. Each patient was followed from date of first dialysis treatment to the end of the study (31/12/2015) or death or renal transplant, whichever occurred first. Cox proportional hazard models were performed to obtain mortality hazard ratios (HR), 95% confidence intervals (CI), for each class of functional activity adjusting for sex, age, country of birth, city of residence, body mass index (BMI), type of nephropathy, vascular access, previous nephrology counselling, weekly hours of hemodialysis, serum albumin, hemoglobin, and presence of comorbidities (e.g. vascular diseases, coronary disease, and diabetes). RESULTS: A total of 3356 patients were studied. In the whole follow-up period, 1622 deaths occurred (48%). Functional impairment was associated with the risk of mortality: compared to 'total autonomy', the HR for 'autonomy in some activities' was 1.30 [95% CI: 1.14-1.49] and for 'not self-sufficient' 1.71 [1.47 1.99] (p for trend < 0.05). The number of evitable deaths attributable to reduced functional activity was 237. CONCLUSION: Functional impairment represents a risk factor for reduced survival in chronic hemodialysis patients. There is a need for early identification of patients who might benefit from interventions aimed at preventing, reversing or delaying the functional impairment.

PMID- 29572625 TI - Predicting personality from network-based resting-state functional connectivity. AB - Personality is associated with variation in all kinds of mental faculties, including affective, social, executive, and memory functioning. The intrinsic dynamics of neural networks underlying these mental functions are reflected in their functional connectivity at rest (RSFC). We, therefore, aimed to probe whether connectivity in functional networks allows predicting individual scores of the five-factor personality model and potential gender differences thereof. We assessed nine meta-analytically derived functional networks, representing social, affective, executive, and mnemonic systems. RSFC of all networks was computed in a sample of 210 males and 210 well-matched females and in a replication sample of 155 males and 155 females. Personality scores were predicted using relevance vector machine in both samples. Cross-validation prediction accuracy was defined as the correlation between true and predicted scores. RSFC within networks representing social, affective, mnemonic, and executive systems significantly predicted self-reported levels of Extraversion, Neuroticism, Agreeableness, and Openness. RSFC patterns of most networks, however, predicted personality traits only either in males or in females. Personality traits can be predicted by patterns of RSFC in specific functional brain networks, providing new insights into the neurobiology of personality. However, as most associations were gender specific, RSFC-personality relations should not be considered independently of gender. PMID- 29572629 TI - A prospective randomized trial of EUS-guided tissue acquisition using a 25-gauge core biopsy needle with and without a stylet. AB - BACKGROUND: Endoscopic ultrasound (EUS)-guided tissue acquisition has become the most effective method of obtaining specimens from a solid lesion adjacent to the gastrointestinal tract. No data exist regarding the use of a stylet in the core biopsy needle during EUS-guided tissue acquisition. The aims of this study were to evaluate the feasibility, safety, and diagnostic yield of a 25-gauge core biopsy needle without (S-) a stylet and to compare its performance with that of a 25-gauge core biopsy needle with (S+) a stylet in patients with solid lesions adjacent to the gastrointestinal tract. METHODS: From November 2013 to January 2016, we performed 114 EUS-guided tissue acquisitions for the diagnosis of solid lesions adjacent to the gastrointestinal tract in a randomized controlled trial. Patients were randomly assigned to the S+ group (n = 57) or the S- group (n = 57). EUS-guided tissue acquisition was performed using a 25-gauge core biopsy needle without an on-site cytopathologist. RESULTS: There were no significant differences in technical success (100 vs. 100%, p = 1.000), the mean number of needle passes (7.0 +/- 1.6 vs. 6.8 +/- 1.5, p = 0.556), needle malfunction (0 vs. 1.8%, p = 1.000), or complications (1.8 vs. 0%, p = 1.000) between the S+ and S- groups. Both groups exhibited comparable outcomes with respect to cytological diagnostic accuracy (93.0 vs. 91.2%, p = 1.000) and histological diagnostic accuracy (86.0 vs. 87.7%, p = 1.000) for malignancy. The procedure time was significantly shorter in the S- group than in the S+ group (32.4 +/- 11.7 vs. 39.7 +/- 8.6 min, p < 0.001). CONCLUSIONS: EUS-guided tissue acquisition using a 25-gauge core biopsy needle without a stylet did not decrease the diagnostic yield for malignancy and was associated with a shorter procedure time than that associated with a stylet. PMID- 29572630 TI - Effect of premedication on lesion detection rate and visualization of the mucosa during upper gastrointestinal endoscopy: a multicenter large sample randomized controlled double-blind study. AB - BACKGROUND: Premedication in upper gastrointestinal endoscopy for higher lesions detection rate has not been well studied so far. This study aimed to confirm whether premedication could improve the detection rate of early cancer or precancerous lesions and mucosal visibility. METHOD: From July 2015 to December 2015, 7200 participants from 6 centers were screened by endoscopy with one of the 4 following premedications randomly: (1) water (group D); (2) pronase (group A); (3) simethicone (group B); (4) pronase and simethicone (group C). Early cancer and precancerous lesions detection rates were taken as the primary endpoints, and mucosal visibility was taken as the secondary endpoint. They were compared among four groups to determine different premedication effects in terms of different anatomical sites. Trial was registered at Chinese Clinical Trial Registry; the registration number is ChiCTR-IOR-17010985. RESULTS: The upper gastrointestinal overall precancerous lesion detection rates among four groups were 8.7, 8.4, 10.0, and 10.3%, the overall early cancer detection rates were 1.3, 1.4%, 1.5, and 1.6%, both without significant difference (p = 0.138 and 0.878). However, the visibility score distributions between control group (D) and premedication groups (A, B, and C) were all statistically significant, with all anatomical sites p values < 0.001. Subgroup analyses, from 2 centers without screening before, also showed significant difference in esophageal (3.9, 3.3, 4.5, and 8.4% with p = 0.004) and overall (7.0, 5.5, 7.3, and 12.0% with p = 0.004) precancerous lesion detection rate. CONCLUSIONS: Premedication with pronase and simethicone may not increase lesion detection rates but could significantly increase the upper gastrointestinal mucosal visibility.

AB - Social insect colonies adopt different levels of survival strategies and exhibit well-defined reproductive division of labour. Oecophylla smaragdina (Fabricius, 1775) has physiological and behavioral adaptations that enable them to forage at extreme environmental conditions and are lethal to most other insects. Ion homeostasis is the key process in an organism's survival mechanism. Among ion pumps, the ATP-dependent sodium-potassium ion pump is essential for maintaining the Na+ and K+ ionic balance and is well known as the primary consumer of energy. Oecophylla smaragdina plays pivotal role as a model among social insects for understanding ion homeostasis at the organization level of the castes. We have evaluated the expression and activity of Na+/K+-ATPase among various castes of O. smaragdina (worker subcastes, queen and male). Real-time PCR and immunoblotting analyses revealed the differential expression of Na+/K+-ATPase in the castes. Significantly higher expression of Na+/K+-ATPase mRNA and protein were observed in the minor workers, queen, major workers and males respectively. These results suggest that in the weaver ant colony, the castes might have variously adapted and evolved with a well-developed ion transport mechanism which allows them to perform allocated tasks within the nest and could be a key to their adaptive benefits towards division of labour. PMID- 29572632 TI - Assessment of the Insecticidal Potential of the Eupatorium buniifolium Essential Oil Against Triatoma infestans (Hemiptera: Reduviidae). A Chiral Recognition Approach. AB - In this research, bioactivities toward the Chagas' disease vector Triatoma infestans (Klug) (Hemiptera: Reduviidae) by the essential oil (EO) of Eupatorium buniifolium H. et A. (Asteraceae) are reported. The tests were designed in order to determine ovicidal activity as well as the response to vapor exposure (fumigant) and to topical application (contact toxicity) and as repellent. In the last three bioassays, nymphs from the 3rd and 4th instar were used. The assayed materials were obtained from aerial parts of plants collected during the months of March and December, throughout 4 years, in two locations. The EO samples were subjected to a qualitative analysis by GC-MS and the relative area of each component was reported by GC-FID. The main monoterpene detected was alpha-pinene and by using a chiral column through GC-MS experiments and having both stereoisomers as standards, we were able to determine that the enantiomer present was S,S-(-)-alpha-pinene. Although usually in studies of EOs changes in chemical composition are often observed due to the time of collection and the environment where the plant develops, in our case the differences were, with some exception, only at the level of the minor components. The best results were obtained in the experiments to determine ovicidal activity, fumigant action, and repellency. No worthy response was found as insecticide in the trials designed for contact toxicity. The results of the studied bioactivities were independent of the location, month, and year of collection of the plant material. This behavior provides an interesting scope in relation to the potential use of this natural blend for the control of this insect at the nymph stage as repellent as well as for decreasing the population by ovicidal effect. Notably, in the course of the two-choice repellency test, it was possible to demonstrate recognition of one of the enantiomers of the alpha-pinene, giving rise to a non-common chirality/response effect. In this assay, the levorotatory isomer was the most active as repellent. Considering the abundance of the wild plant under study and the fact that its EO is easy to obtain, it is suggested that it could be an adequate natural resource to control this vector in a sustainable way as a complementary approach to conventional methods.

AB - PURPOSE: To make individualised preoperative prediction of non-functioning pituitary adenoma (NFPAs) subtypes between null cell adenomas (NCAs) and other subtypes using a radiomics approach. METHODS: We enrolled 112 patients (training set: n = 75; test set: n = 37) with complete T1-weighted magnetic resonance imaging (MRI) and contrast-enhanced T1-weighted MRI (CE-T1). A total of 1482 quantitative imaging features were extracted from T1 and CE-T1 images. Support vector machine trained a predictive model that was validated using a receiver operating characteristics (ROC) analysis on an independent test set. Moreover, a nomogram was constructed incorporating clinical characteristics and the radiomics signature for individual prediction. RESULTS: T1 image features yielded area under the curve (AUC) values of 0.8314 and 0.8042 for the training and test sets, respectively, while CE-T1 image features provided no additional contribution to the predictive model. The nomogram incorporating sex and the T1 radiomics signature yielded good calibration in the training and test sets (concordance index (CI) = 0.854 and 0.857, respectively). CONCLUSION: This study focused on the preoperative prediction of NFPA subtypes between NCAs and others using a radiomics approach. The developed model yielded good performance, indicating that radiomics had good potential for the preoperative diagnosis of NFPAs. KEY POINTS: * MRI may help in the pre-operative diagnosis of NFPAs subtypes * Retrospective study showed T1-weighted MRI more useful than CE-T1 in NCAs diagnosis * Treatment decision making becomes more individualised * Radiomics approach had potential for classification of NFPAs. PMID- 29572635 TI - Automated estimation of image quality for coronary computed tomographic angiography using machine learning. AB - OBJECTIVES: Our goal was to evaluate the efficacy of a fully automated method for assessing the image quality (IQ) of coronary computed tomography angiography (CCTA). METHODS: The machine learning method was trained using 75 CCTA studies by mapping features (noise, contrast, misregistration scores, and un interpretability index) to an IQ score based on manual ground truth data. The automated method was validated on a set of 50 CCTA studies and subsequently tested on a new set of 172 CCTA studies against visual IQ scores on a 5-point Likert scale. RESULTS: The area under the curve in the validation set was 0.96. In the 172 CCTA studies, our method yielded a Cohen's kappa statistic for the agreement between automated and visual IQ assessment of 0.67 (p < 0.01). In the group where good to excellent (n = 163), fair (n = 6), and poor visual IQ scores (n = 3) were graded, 155, 5, and 2 of the patients received an automated IQ score > 50 %, respectively. CONCLUSION: Fully automated assessment of the IQ of CCTA data sets by machine learning was reproducible and provided similar results compared with visual analysis within the limits of inter-operator variability. KEY POINTS: * The proposed method enables automated and reproducible image quality assessment. * Machine learning and visual assessments yielded comparable estimates of image quality. * Automated assessment potentially allows for more standardised image quality. * Image quality assessment enables standardization of clinical trial results across different datasets. PMID- 29572636 TI - Apparent diffusion coefficient for molecular subtyping of non-gadolinium enhancing WHO grade II/III glioma: volumetric segmentation versus two-dimensional region of interest analysis. AB - OBJECTIVES: To investigate if quantitative apparent diffusion coefficient (ADC) measurements can predict genetic subtypes of non-gadolinium-enhancing gliomas, comparing whole tumour against single slice analysis. METHODS: Volumetric T2 derived masks of 44 gliomas were co-registered to ADC maps with ADC mean (ADCmean) calculated. For the slice analysis, two observers placed regions of interest in the largest tumour cross-section. The ratio (ADCratio) between ADCmean in the tumour and normal appearing white matter was calculated for both methods. RESULTS: Isocitrate dehydrogenase (IDH) wild-type gliomas showed the lowest ADC values throughout (p < 0.001). ADCmean in the IDH-mutant 1p19q intact group was significantly higher than in the IDH-mutant 1p19q co-deleted group (p < 0.01). A volumetric ADCmean threshold of 1201 * 10-6 mm2/s identified IDH wild type with a sensitivity of 83% and a specificity of 86%; a volumetric ADCratio cut-off value of 1.65 provided a sensitivity of 80% and a specificity of 92% (area under the curve (AUC) 0.9-0.94). A slice ADCratio threshold for observer 1 (observer 2) of 1.76 (1.83) provided a sensitivity of 80% (86%), specificity of 91% (100%) and AUC of 0.95 (0.96). The intraclass correlation coefficient was excellent (0.98). CONCLUSIONS: ADC measurements can support the distinction of glioma subtypes. Volumetric and two-dimensional measurements yielded similar results in this study. KEY POINTS: * Diffusion-weighted MRI aids the identification of non-gadolinium-enhancing malignant gliomas * ADC measurements may permit non-gadolinium-enhancing glioma molecular subtyping * IDH wild-type gliomas have lower ADC values than IDH-mutant tumours * Single cross-section and volumetric ADC measurements yielded comparable results in this study. PMID- 29572638 TI - Clinical outcomes following arthroscopic treatment of femoro-acetabular impingement using a minimal traction approach and an initial capsulotomy. Minimum two year follow-up. AB - PURPOSE: Although the arthroscopic management of femoroacetabular impingement (FAI) is increasing, severe complications have been reported due to traction. We developed an arthroscopic technique based on an initial capsulotomy and a minimal traction approach. The main purpose of this study was to analyze the clinical outcomes of FAI treatment using this technique after at least two years of follow up. METHODS: Forty-seven consecutive patients underwent surgery for FAI. There were two initial portals: a proximal anterolateral portal and a distal anterior instrumental portal. An anterior working space was created and a T-shaped incision was made in the anterior capsule to relieve joint distraction. Short traction (less than 20 mn) made it possible to approach the central compartment. Acetabuloplasty was performed in the presence of pincer impingement. Traction was then released. A head-neck femoral osteochondroplasty was performed in case of bump impingement. All patients underwent a mean 3.3 +/- one years of follow-up based on two self-administered questionnaires: the Harris hip score and the QOL Oxford score. None of the patients were lost to follow-up. RESULTS: There were three complications: two ossifications and one case of injury to the femoral cutaneous nerve with good clinical outcomes at the final follow-up. Five patients (10%) underwent surgical revision after a mean 1.4 years of follow-up: three total hip arthroplasties, one peri-acetabular osteotomy, and one repeat arthroscopic hip debridement. The Harris score increased significantly from 60 +/ 10 to 86 +/- 15 (p < 0.0001) and the Oxford score improved from 34 +/- 15 to 50 +/- 11. Only 25% of patients had a "forgotten hip" at the final follow-up. CONCLUSION: Our clinical results were comparable to previously reported outcomes with other surgical techniques for the management of FAI. However, it should also be noted that despite these good clinical outcomes, the percentage of patients with a "forgotten hip" is low, and patients should be informed of this. PMID- 29572637 TI - Observer variability of reference tissue selection for relativecerebral blood volume measurements in glioma patients. AB - OBJECTIVES: To assess observer variability of different reference tissues used for relative CBV (rCBV) measurements in DSC-MRI of glioma patients. METHODS: In this retrospective study, three observers measured rCBV in DSC-MR images of 44 glioma patients on two occasions. rCBV is calculated by the CBV in the tumour hotspot/the CBV of a reference tissue at the contralateral side for normalization. One observer annotated the tumour hotspot that was kept constant for all measurements. All observers annotated eight reference tissues of normal white and grey matter. Observer variability was evaluated using the intraclass correlation coefficient (ICC), coefficient of variation (CV) and Bland-Altman analyses. RESULTS: For intra-observer, the ICC ranged from 0.50-0.97 (fair excellent) for all reference tissues. The CV ranged from 5.1-22.1 % for all reference tissues and observers. For inter-observer, the ICC for all pairwise observer combinations ranged from 0.44-0.92 (poor-excellent). The CV ranged from 8.1-31.1 %. Centrum semiovale was the only reference tissue that showed excellent intra- and inter-observer agreement (ICC>0.85) and lowest CVs (<12.5 %). Bland Altman analyses showed that mean differences for centrum semiovale were close to zero. CONCLUSION: Selecting contralateral centrum semiovale as reference tissue for rCBV provides the lowest observer variability. KEY POINTS: * Reference tissue selection for rCBV measurements adds variability to rCBV measurements. * rCBV measurements vary depending on the choice of reference tissue. * Observer variability of reference tissue selection varies between poor and excellent. * Centrum semiovale as reference tissue for rCBV provides the lowest observer variability. PMID- 29572639 TI - Can patients manage toileting after reverse total shoulder arthroplasty? A systematic review. AB - PURPOSE: A major concern for patients undergoing reverse total shoulder arthroplasty (RTSA) is managing toileting after surgery. The goals of this systematic review of RTSA studies were to determine the following: (1) the percentage of patients who can manage toileting, (2) their degree of difficulty with toileting, and (3) the percentage of patients who can manage toileting after bilateral versus unilateral RTSA. METHODS: Medline, EMBASE, Google Scholar, and the Cochrane Central Register of Controlled Trials were searched for studies reporting the ability to manage toileting after RTSA. Six studies with at least 12 months of follow-up were included, yielding 183 patients (105 unilateral RTSA, 78 bilateral RTSA). We pooled patient data and calculated the weighted mean proportion of patients able to manage toileting, those who reported difficulty, and those able to manage toileting after unilateral versus bilateral RTSA. Statistical significance was set at P < 0.05. RESULTS: Most patients (92%; 95% confidence interval, 87-95%) were able to manage toileting after RTSA. Some degree of difficulty with toileting was reported for 20% of all shoulders. Almost all patients with bilateral RTSA were able to manage toileting with at least one arm (weighted mean proportion 97%; 95% confidence interval, 88-99%). There was no significant difference in the proportion of patients able to manage toileting after unilateral versus bilateral RTSA (P = 0.08). Only 3% of all papers published on the clinical results of RTSA by June 2017 reported upon toileting after the procedure. CONCLUSIONS: With the available evidence, most patients were able to manage toileting after RTSA, although one-fifth reported some degree of difficulty. Ability to manage toileting was similar after unilateral versus bilateral RTSA. In the future, this variable should be a standard question after shoulder arthroplasty. LEVEL OF EVIDENCE: IV. PMID- 29572641 TI - Chronic Essex-Lopresti injury: a systematic review of current treatment options. AB - INTRODUCTION: Essex-Lopresti lesion (ELL) is a severe injury. Most of ELL is recognized in chronic phase representing a therapeutic challenge for orthopaedic surgeons. The aim of this systematic review is to highlight and criticize current concepts in the surgical treatment. MATERIALS AND METHODS: The search was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline. A comprehensive research of Pubmed database was made using the following Mesh term: ((Essex-Lopresti injury) OR (Essex Lopresti) OR (distal radio ulnar dissociation) OR (distal radio ulnar dislocation) OR (longitudinal forearm instability)). Quality assessment of each article was performed according to Coleman score by two authors. RESULTS: Eight full articles were included to the systematic review. Surgical treatment was differentiated in five categories according to the most common procedure reported in clinical series. The mean Coleman Score was 51.13 +/- 9.76. DISCUSSION: Case series reported in the literature include a limited number of patients with chronic ELL. Currently, salvage procedure devoted to treat a wrong diagnosis and an incorrect treatment is used. Radial head replacement together with ulnar shortening osteotomy and interosseous membrane reconstruction are the most common treatments of choice, but at present, there is not yet a shared scheme of management for patients with chronic ELL. CONCLUSIONS: According to current literature, a case by-case treatment must always be considered. Further investigations, with higher level of evidence, quality of study design, and number of patients, are needed to better assess clinical results and complication of each technique. LEVEL OF EVIDENCE: IV. PMID- 29572640 TI - Quality of life of patients with osteonecrosis of the femoral head: a multicentre study. AB - PURPOSE: Quality-of-life (QOL) assessments in patients with osteonecrosis of the femoral head (ONFH) have rarely been reported. This multicentre study aimed to elucidate the relationship between disease severity, including necrotic lesion type and radiological staging, and QOL, as well as between patients' characteristics and QOL. METHODS: Two hundred seventy-four patients with ONFH (108 females, 166 males; median age, 46 years) were asked to complete self assessment QOL questionnaires including the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire, Oxford Hip Score, and SF-12v2. RESULTS: Patients with large necrotic lesion type or collapsed ONFH had low QOL scores. Among patients with non-collapsed lesions, patients with alcohol-associated ONFH had lower QOL scores than those with steroid-associated ONFH, those with bilateral ONFH had lower mental scores, and male patients had worse social condition scores. Among patients with collapsed lesions, middle-aged patients exhibited lower mental QOL, and a strong correlation was observed between social activity and mental health. CONCLUSION: Collapsed ONFH was associated with low QOL scores. Among patients with non-collapsed lesions, alcohol-associated ONFH, bilateral disease, and male sex were linked to low QOL scores.

AB - Despite advances in antiarrhythmic and device therapy, ventricular tachycardia (VT) continues to be a major cause of increased morbidity and mortality. During scar-mediated monomorphic ventricular tachycardia ablation, the search for critical isthmus sites continues to be the primary goal during successful ablative procedures. However, given the overwhelming hemodynamic instability of most ventricular arrhythmias (> 70%), VT ablation is increasingly performed during sinus rhythm. This technique requires either a greater reliance on isthmus surrogates, or more extensive ablation techniques and is a more probabilistic approach to substrate modification. We believe that a better understanding of scar physiology and activation during sinus rhythm has important implications for clinical workflow and mechanistic improvements with current ablation strategies. With advancements in high-density mapping and multi-electrode catheter technology, mapping of VT substrates is performed with higher resolution, with improved visualization of local abnormal ventricular activities (LAVA), and with a more nuanced functional understanding of late potentials. As a prerequisite, our practice for VT ablation starts with a high-density structural map to identify voltage abnormalities as well as an isochronal functional map of sinus rhythm activation to identify region of discontinuous wavefront propagation. As the era of increased automation has emerged, there continues to be vast array of customizable features, and we have adopted the use of multiple wavefront mapping to further elucidate possible arrhythmogenic substrate. Our emerging understanding of how scar propagation patterns relate to areas of abnormal signals and critical isthmuses may greatly improve the ability to identify surrogates during sinus rhythm and help localize the most arrhythmogenic regions within a given scar. In the hemodynamically unstable patients, we routinely integrate isochronal late activation mapping (ILAM) to identify areas of slow conduction to initiate our targeted ablation and substrate modification. Multi electrode delineation of the entire reentrant VT circuit has value in understanding the size of the circuit, rotational nature, and transmural extent of human reentry. Correlative studies between the activation of the complete VT circuit and sinus rhythm are likely to provide important mechanistic insights on where fixed and/or functional block occurs within a complex scar substrate. PMID- 29572644 TI - Expression of a Constitutively Active Human Insulin Receptor in Hippocampal Neurons Does Not Alter VGCC Currents. AB - Memory and cognitive decline are the product of numerous physiological changes within the aging brain. Multiple theories have focused on the oxidative, calcium, cholinergic, vascular, and inflammation hypotheses of brain aging, with recent evidence suggesting that reductions in insulin signaling may also contribute. Specifically, a reduction in insulin receptor density and mRNA levels has been implicated, however, overcoming these changes remains a challenge. While increasing insulin receptor occupation has been successful in offsetting cognitive decline, alternative molecular approaches should be considered as they could bypass the need for brain insulin delivery. Moreover, this approach may be favorable to test the impact of continued insulin receptor signaling on neuronal function. Here we used hippocampal cultures infected with lentivirus with or without IRbeta, a constitutively active, truncated form of the human insulin receptor, to characterize the impact continued insulin receptor signaling on voltage-gated calcium channels. Infected cultures were harvested between DIV 13 and 17 (48 h after infection) for Western blot analysis on pAKT and AKT. These results were complemented with whole-cell patch-clamp recordings of individual pyramidal neurons starting 96 h post-infection. Results indicate that while a significant increase in neuronal pAKT/AKT ratio was seen at the time point tested, effects on voltage-gated calcium channels were not detected. These results suggest that there is a significant difference between constitutively active insulin receptors and the actions of insulin on an intact receptor, highlighting potential alternate mechanisms of neuronal insulin resistance and mode of activation. PMID- 29572646 TI - Knockout of Amyloid beta Protein Precursor (APP) Expression Alters Synaptogenesis, Neurite Branching and Axonal Morphology of Hippocampal Neurons. AB - The function of the beta-A4 amyloid protein precursor (APP) of Alzheimer's disease (AD) remains unclear. APP has a number of putative roles in neuronal differentiation, survival, synaptogenesis and cell adhesion. In this study, we examined the development of axons, dendrites and synapses in cultures of hippocampus neutrons derived from APP knockout (KO) mice. We report that loss of APP function reduces the branching of cultured hippocampal neurons, resulting in reduced synapse formation. Using a compartmentalised culture approach, we found reduced axonal outgrowth in cultured hippocampal neurons and we also identified abnormal growth characteristics of isolated hippocampal neuron axons. Although APP has previously been suggested to play an important role in promoting cell adhesion, we surprisingly found that APPKO hippocampal neurons adhered more strongly to a poly-L-lysine substrate and their neurites displayed an increased density of focal adhesion puncta. The findings suggest that the function of APP has an important role in both dendritic and axonal growth and that endogenous APP may regulate substrate adhesion of hippocampal neurons. The results may explain neuronal and synaptic morphological abnormalities in APPKO mice and the presence of abnormal APP expression in dystrophic neurites around amyloid deposits in AD. PMID- 29572645 TI - Effects of the Serotonin 5-HT1A Receptor Biased Agonists, F13714 and F15599, on Striatal Neurotransmitter Levels Following L-DOPA Administration in Hemi Parkinsonian Rats. AB - Peak-dose dyskinesia is associated with the dramatic increase in striatal dopamine levels that follows L-DOPA administration. The 'false neurotransmitter' hypothesis postulates that the latter is likely due to an aberrant processing of L-DOPA by serotonergic neurons. In keeping with this hypothesis, two highly selective 'biased agonists' of 5-HT1A receptors-namely F13714 and F15599 (NLX 101)-were recently shown to exhibit exceptionally potent anti-dyskinetic activity without impairing L-DOPA therapeutic properties despite their differential targeting of 5-HT1A receptor sub-populations. In this study, we investigated whether these two compounds dampened peak L-DOPA-induced dopamine microdialysate levels in the striatum of hemi-parkinsonian rats. Acute administration of either F13714 (0.04 and 0.16 mg/kg i.p.) or F15599 (0.16 and 0.64 mg/kg, i.p.) blunted L DOPA (2 mg/kg)-induced increases in dopamine microdialysate levels in the denervated striatum (following unilateral injection of 6-OHDA into the medial forebrain bundle). No significant changes were observed on the intact side of the brain. Concurrently, both drugs profoundly reduced striatal serotonin levels on both sides of the brain. In addition, F13714 and F15599, in the presence of L DOPA, produced a dose-dependent increase in glutamate levels, but this effect was restricted to later time points. These finding support the interpretation that F13714 and F15599 mediate their anti-dyskinetic effects by blunting of the peak in dopamine levels via activation of somatodendritic serotonin 5-HT1A receptors and the consequent inhibition of serotonergic neurons. This study adds to the growing body of evidence supporting the development of a potent 5-HT1A receptor agonist for treatment of peak-dose dyskinesia. PMID- 29572647 TI - Neuroblastoma: clinical and biological approach to risk stratification and treatment. AB - Neuroblastoma is the most common extra-cranial solid tumor of childhood and the most common in the first year of life. It is a unique malignancy in that infants often present with either localized or metastatic disease that can spontaneously regress without intervention while older children can succumb to the disease after months to years of arduous therapy. Given this wide range of outcomes, the International Neuroblastoma Risk Group was created to stratify patients based on presenting characteristics and tumor biology in order to guide intensity of treatment strategies. The goal has been to decrease therapy for low-risk patients to avoid long-term complications while augmenting and targeting therapies for high-risk patients to improve overall survival. The international risk stratification depends on age, stage, histology, MYCN gene amplification status, tumor cell ploidy and segmental chromosomal abnormalities. Treatment for asymptomatic low-risk patients with an estimated survival of > 98% is often observation or surgical resection alone, whereas intermediate-risk patients with an estimated survival of > 90% require moderate doses of response-adjusted chemotherapy along with resection. High-risk patients undergo multiple cycles of combination chemotherapy before surgery, followed by consolidation with myeloablative autologous hematopoietic stem cell transplantation and local radiation and finally immunotherapy with differentiation therapy as maintenance phase. With this approach, outcome for patients with neuroblastoma has improved, as the field continues to expand efforts in more targeted therapies for high-risk patients. PMID- 29572648 TI - The approach of visual stimuli influences expectations about stimulus types for subsequent somatosensory stimuli. AB - It is known that perceiving a visual stimulus influences the processing of subsequent somatosensory stimuli. In particular, an emotion-laden visual stimulus influences the processing of types of subsequent somatosensory stimuli. Additionally, visual stimuli approaching the body facilitate spatial and temporal expectations about subsequent somatosensory stimuli even if the visual stimuli do not contain emotional information; however, it remains unclear whether the approach of non-emotional visual stimuli also influences such expectations. To investigate whether the approach of non-emotional visual stimuli influences expectations about types of subsequent somatosensory stimuli, event-related brain potentials (ERPs) during a simple reaction time task using somatosensory stimuli were recorded. Specific colors of visual stimuli and types of somatosensory stimuli were combined to form congruent and incongruent trials. In the congruent trials, specific combinations (e.g., blue color and a single pulse) were presented (80% of the trials), whereas in the incongruent trials, different combinations (e.g., blue color and a train pulse) were presented (20% of the trials). Under the approach condition, the visual stimuli sequentially approached the wrist to which the somatosensory stimulus was presented. In the neutral condition, the visual stimuli did not approach. The results of the ERP analysis showed that incongruence evoked a P3 response with larger amplitude under the approach condition than under the neutral condition. This result suggests that visual stimuli that approach the body function as clues regarding the types of subsequent somatosensory stimuli even if the visual stimuli do not contain emotional information. PMID- 29572649 TI - Postural responses to target jumps and background motion in a fast pointing task. AB - When reaching towards an object while standing, one's hand responds very quickly to visual perturbations such as the target being displaced or the background moving. Such responses require postural adjustments. When the background moves, its motion might be attributed to self-motion in a stable world, and thereby induce compensatory postural adjustments that affect the hand. The changes in posture associated with a given hand movement response may, therefore, be different for the two types of perturbations. To see whether they are, we asked standing participants to move their hand in the sagittal direction away from their body to targets displayed on a horizontal screen in front of them. The target displacements and background motion were in the lateral direction. We found hand movement responses that were in line with earlier reports, with a latency that was slightly shorter for target displacements than for background motion, and that was independent of target displacement size or background motion speed. The trunk responded to both perturbations with a modest lateral sway. The two main findings were that the upper trunk responded even before the hand did so and that the head responded to background motion but hardly responded to target displacements. These findings suggest that postural adjustments associated with adjusting the hand movement precede the actual adjustments to the movement of the hand, while at the same time, participants try to keep their head stable on the basis of visual information.

The aim of this study was to assess whether the extent of finger force enslaving changes with aging during a task that involves both static and dynamic phases. Ten right-handed young (22-30 years) and ten elderly subjects (67-79 years) were instructed to first exert a constant force (static phase) and then flex their index finger while counteracting constant resistance forces orthogonal to their fingertips (dynamic phase). The other fingers (non-instructed) were held in extension. EMG activities of the flexor digitorum superficialis (FDS) and extensor digitorum (ED) muscles in the regions corresponding to the index, middle and ring fingers together with their forces and position of index finger were measured. In both elderly and young, forces exerted by the non-instructed fingers increased (around 0.6 N for both young and elderly) during isotonic flexion of the index finger, but with a different delay of on average 100 +/- 72 ms in elderly and 334 +/- 101 ms in young subjects. Results also suggest different responses in activity of FDS and ED muscle regions of the non-instructed fingers to index finger flexion between elderly and young subjects. The enslaving effect was significantly higher in elderly than in young subjects both in the static (12% more) and dynamic (14% more) phases. These differences in enslaving can at least partly be explained by changes in neuromuscular control.

AB - RATIONALE: We have recently shown that the benzodiazepine diazepam inhibits dopamine release in the NAc and blocks the increased release of dopamine induced by DL-amphetamine. Rewarding stimuli and many drugs of abuse can induce dopamine release in the nucleus accumbens as well as 50-kHz ultrasonic vocalizations (USVs) in rats. OBJECTIVES: In the present study, we tested the hypothesis that diazepam can also block the increase in locomotor activity and USVs elicited by amphetamine. METHODS: Fifty-kilohertz USVs, stereotypy, and locomotor behavior were scored in adult male Wistar rats treated with i.p. injections of saline, 3 mg/kg DL-amphetamine, 2 mg/kg diazepam, 0.2 mg/kg haloperidol, or a combination of these drugs. RESULTS: In agreement with previous studies, amphetamine caused significant increases in the number of USV calls, stereotypies, and locomotor activity. The D2 dopamine receptor antagonist haloperidol blocked the effects of amphetamine on USVs, stereotypy, and locomotor activity. Diazepam blocked the effect of amphetamine on USV and stereotypy, but not on horizontal locomotion. CONCLUSIONS: These results suggest that diazepam blocks the rewarding effect of amphetamine. This finding is promising for basic research regarding treatments of substance use disorders and evaluation of the impact of benzodiazepines on motivation. PMID- 29572652 TI - Differential regulation of alcohol taking and seeking by antagonism at alpha4beta2 and alpha3beta4 nAChRs. AB - RATIONALE: Alcoholism is a serious public health problem throughout the world. Current pharmacotherapies for the treatment of this disorder are poorly effective. Preclinical and clinical findings point to nicotinic acetylcholine receptors (nAChRs) as a promising target for the development of novel and effective medications. Assuage Pharmaceuticals, in collaboration with Torrey Pines Institute for Molecular Studies, has discovered a new class of potent and selective alpha4beta2 nAChR antagonists. OBJECTIVE: Here, it was hypothesized that alpha4beta2 nAChR antagonism is a viable approach for treatment of alcohol use disorders. RESULTS: When tested in rats, one lead compound, AP-202, attenuated both operant alcohol and nicotine self-administration in a paradigm in which the two reinforcers were concurrently available. The conotoxin TP2212-59, a selective alpha3beta4 nAChR antagonist, was only effective in reducing nicotine self-administration. AP-202 also reduced alcohol but not food responding when alcohol was presented as the only reinforcer, whereas the commercially available alpha4beta2 nAChR antagonist dihydro-beta-erythroidine failed to alter alcohol self-administration. AP-202 did not block relapse-like behavior induced by previously alcohol-associated stimuli or yohimbine stress. In a reinstatement paradigm, in which alcohol seeking was triggered by a nicotine challenge, a behavior successfully inhibited by the nonselective nAChR antagonist mecamylamine, AP-202 was not effective, while pretreatment with TP2212-59 abolished nicotine-induced reinstatement of alcohol seeking. CONCLUSIONS: These findings suggest differential roles for alpha4beta2 and alpha3beta4 nAChR on alcohol taking and seeking with selective blockade of alpha4beta2 nAChR being more implicated in modulating alcohol taking while selective blockade of alpha3beta4 nAChR is involved in nicotine-induced alcohol seeking. PMID- 29572654 TI - The difference in visuomotor feedback velocity control during spiral drawing between Parkinson's disease and essential tremor. AB - In a spiral task, the accuracy of the spiral trajectory, which is affected by tracing or tracking ability, differs between patients with Parkinson's disease (PD) and essential tremor (ET). However, not many studies have analyzed velocity differences between the groups during this task. This study aimed to examine differences between the groups related to this characteristic using a tablet. Fourteen PD, 12 ET, and 12 control group participants performed two tasks: tracing a given spiral (T1) and following a guiding point (T2). A digitized tablet was used to record movements and trajectory. Effects of direct visual feedback on intergroup and intragroup velocity were measured. Although PD patients had a significantly lower T1 velocity than the control group (p < 0.05), they could match the velocity of the guiding point (3.0 cm/s) in T2. There was no significant difference in the average T1 velocity between ET and the control groups (p = 0.26); however, the T2 velocity of ET patients was significantly higher than the control group (p < 0.05). They were also unable to adjust the velocity to match the guiding point, indicating that ET patients have a poorer ability to follow dynamic guidance. When both groups of patients have similar action tremor severity, their ability to follow dynamic guidance was still significantly different. Our study combined visual feedback with spiral drawing and demonstrated differences in the following-velocity distribution in PD and ET. This method may be used to distinguish the tremor presentation of both diseases, and thus, provide accurate diagnosis.

PMID- 29572653 TI - Delta/mu opioid receptor interactions in operant conditioning assays of pain depressed responding and drug-induced rate suppression: assessment of therapeutic index in male Sprague Dawley rats. AB - RATIONALE AND OBJECTIVES: Although delta/mu receptor interactions vary as a function of behavioral endpoint, there have been no assessments of these interactions using assays of pain-depressed responding. This is the first report of delta/mu interactions using an assay of pain-depressed behavior. METHODS: A mult-cycle FR10 operant schedule was utilized in the presence of (nociception) and in the absence of (rate suppression) a lactic acid inflammatory pain-like manipulation. SNC80 and methadone were used as selective/high efficacy delta and mu agonists, respectively. Both SNC80 and methadone alone produced a dose dependent restoration of pain-depressed responding and dose-dependent response rate suppression. Three fixed ratio mixtures, based on the relative potencies of the drugs in the nociception assay, also produced dose-dependent antinociception and sedation. Isobolographic analysis indicated that all three mixtures produced supra-additive antinociceptive effects and simply additive sedation effects. CONCLUSIONS: The therapeutic index (TI) inversely varied as a function of amount of SNC80 in the mixture, such that lower amounts of SNC80 produced a higher TI, and larger amounts produced a lower TI. Compared to literature using standard pain-elicited assays, the orderly relationship between SNC80 and TI reported here may be a unique function of assessing pain-depressed behavior. PMID- 29572656 TI - The importance of endpoint selection: How effective does a drug need to be for success in a clinical trial of a possible Alzheimer's disease treatment? AB - To date, Alzheimer's disease (AD) clinical trials have been largely unsuccessful. Failures have been attributed to a number of factors including ineffective drugs, inadequate targets, and poor trial design, of which the choice of endpoint is crucial. Using data from the Alzheimer's Disease Neuroimaging Initiative, we have calculated the minimum detectable effect size (MDES) in change from baseline of a range of measures over time, and in different diagnostic groups along the AD development trajectory. The Functional Activities Questionnaire score had the smallest MDES for a single endpoint where an effect of 27% could be detected within 3 years in participants with Late Mild Cognitive Impairment (LMCI) at baseline, closely followed by the Clinical Dementia Rating Sum of Boxes (CDRSB) score at 28% after 2 years in the same group. Composite measures were even more successful than single endpoints with an MDES of 21% in 3 years. Using alternative cognitive, imaging, functional, or composite endpoints, and recruiting patients that have LMCI could improve the success rate of AD clinical trials. PMID- 29572658 TI - Evaluation of the dislocation and long-term sonographic detectability of a hydrogel-based breast biopsy site marker. AB - PURPOSE: To evaluate the usefulness of the HydroMARK, a hydrogel-based breast biopsy site marker for ultrasound localization of breast lesions, we investigated the tendency for dislocation and sonographic detectability of the marker placed in patients. MATERIALS AND METHODS: The marker was placed in lesions that were expected to become obscured after biopsy for a suspicious breast lesion or after neoadjuvant chemotherapy for breast cancer. The patients consented to return for a repeat ultrasound +/- mammography examination, and the degree of displacement of the marker was measured as the marker-to-residual lesion distance. RESULTS: The marker was placed after stereotactic biopsy, ultrasound-guided biopsy, and before/during neoadjuvant chemotherapy, in 11, 22, and 7 lesions, respectively. Surgical resection was performed for 22 of the 40 lesions, while remaining 18 benign lesions were followed. The marker was sonographically detectable in 89.7% (35/39), 100% (35/35), and 100% (18/18) of the cases, respectively, at a median of 8 days, 13 weeks, and 11 months after the deployment. The degree of displacement was lower in the ultrasound-guided placement group than in the stereotactic placement group (median displacement: 0 vs. 4.3 mm; p = 0.001), it was also lower in the core-needle biopsy and neoadjuvent therapy cases than in the vacuum-assisted biopsy cases (p = 0.003). At a median interval of 2.5 months after deployment, the marker remained unchanged in location in all cases (n = 18, p = NS). CONCLUSIONS: The HydroMARK appears to be a safe and effective marker with the advantageous characteristics of a low tendency for dislocation with time and long-term sonographic detectability. PMID- 29572657 TI - A guanine insert in OsBBS1 leads to early leaf senescence and salt stress sensitivity in rice (Oryza sativa L.). AB - KEY MESSAGE: A rice receptor-like kinase gene OSBBS1/OsRLCK109 was identified; this gene played vital roles in leaf senescence and the salt stress response. Early leaf senescence can cause negative effects on rice yield, but the underlying molecular regulation is not fully understood. bilateral blade senescence 1 (bbs1), an early leaf senescence mutant with a premature senescence phenotype that occurs mainly performing at the leaf margins, was isolated from a rice mutant population generated by ethylmethane sulfonate (EMS) treatment. The mutant showed premature leaf senescence beginning at the tillering stage and exhibited severe symptoms at the late grain-filling stage. bbs1 showed accelerated dark-induced leaf senescence. The OsBBS1 gene was cloned by a map based cloning strategy, and a guanine (G) insertion was found in the first exon of LOC_Os03g24930. This gene encodes a receptor-like cytoplasmic kinase and was named OsRLCK109 in a previous study. Transgenic LOC_Os03g24930 knockout plants generated by a CRISPR/Cas9 strategy exhibited similar early leaf senescence phenotypes as did the bbs1 mutant, which confirmed that LOC_Os03g24930 was the OsBBS1 gene. OsBBS1/OsRLCK109 was expressed in all detected tissues and was predominantly expressed in the main vein region of mature leaves. The expression of OsBBS1 could be greatly induced by salt stress, and the bbs1 mutant exhibited hypersensitivity to salt stress. In conclusion, this is the first identification of OsRLCKs participating in leaf senescence and playing critical roles in the salt stress response in rice (Oryza sativa L.). PMID- 29572659 TI - Reduced oligodendrocyte density in layer 5 of the prefrontal cortex in schizophrenia. AB - Neuroimaging and post-mortem studies have implicated altered myelin integrity and oligodendrocyte abnormalities in the dysfunction of neuronal network in schizophrenia, including the prefrontal cortex, Brodmann area (BA) 10. Pyramidal neurons in layer 5 of BA10 are the important link of reciprocal frontal cortical basal ganglia-thalamic circuits altered in schizophrenia. Previously, we found ultrastructural dystrophic and degenerative alterations of oligodendrocytes in layer 5 of BA10 in schizophrenia. The aim of the study was to estimate the numerical density (Nv) of oligodendrocytes in layer 5 of BA10 in schizophrenia as compared to normal controls. 17 chronic schizophrenia subjects and 22 healthy matched controls were studied in Nissl-stained sections using optical disector method. Group differences were analyzed using ANCOVA followed by post hoc Duncan's test. The Nv of oligodendrocytes was significantly lower (- 32%, p < 0.001) in the schizophrenia group as compared to the control group. Young controls (age < 50 years old) showed significantly higher Nv of oligodendrocytes as compared to elderly controls (age > 50 years old). Young and elderly schizophrenia subgroups did not differ significantly. Both control subgroups have significantly higher Nv of oligodendrocytes as compared to the schizophrenia subgroups. Decreased Nv of oligodendrocytes found in layer 5 of BA10 may be the result of dystrophic and destructive alterations and/or disrupted development of oligodendrocytes in schizophrenia. PMID- 29572660 TI - Surface morphology of the orbitofrontal cortex in individuals at risk of psychosis: a multicenter study. AB - Changes in the surface morphology of the orbitofrontal cortex (OFC), such as a fewer orbital sulci and altered sulcogyral pattern of the 'H-shaped' orbital sulcus, have been reported in schizophrenia, possibly reflecting abnormal neurodevelopment during gestation. However, whether high-risk subjects for developing psychosis also exhibit these gross morphologic anomalies is not well documented. This multicenter MRI study from four scanning sites in Japan investigated the distribution of the number of intermediate and posterior orbital sulci, as well as the OFC sulcogyral pattern, in 125 individuals with an at-risk mental state (ARMS) [of whom 22 later developed psychosis (ARMS-P) and 89 did not (ARMS-NP)] and 110 healthy controls. The ARMS group as a whole had a significantly lower number of intermediate and posterior orbital sulci compared with the controls, which was associated with prodromal symptomatology. However, there was no group difference in OFC pattern distribution. The ARMS-P and -NP groups did not differ in OFC surface morphology. These results suggest that gross morphology of the OFC in high-risk subjects may at least partly reflect neurodevelopmental pathology related to vulnerability to psychosis. PMID- 29572661 TI - Identification and functional analysis of the NLP-encoding genes from the phytopathogenic oomycete Phytophthora capsici. AB - Phytophthora capsici is a hemibiotrophic, phytopathogenic oomycete that infects a wide range of crops, resulting in significant economic losses worldwide. By means of a diverse arsenal of secreted effector proteins, hemibiotrophic pathogens may manipulate plant cell death to establish a successful infection and colonization. In this study, we described the analysis of the gene family encoding necrosis- and ethylene-inducing peptide 1 (Nep1)-like proteins (NLPs) in P. capsici, and identified 39 real NLP genes and 26 NLP pseudogenes. Out of the 65 predicted NLP genes, 48 occur in groups with two or more genes, whereas the remainder appears to be singletons distributed randomly among the genome. Phylogenetic analysis of the 39 real NLPs delineated three groups. Key residues/motif important for the effector activities are degenerated in most NLPs, including the nlp24 peptide consisting of the conserved region I (11-aa immunogenic part) and conserved region II (the heptapeptide GHRHDWE motif) that is important for phytotoxic activity. Transcriptional profiling of eight selected NLP genes indicated that they were differentially expressed during the developmental and plant infection phases of P. capsici. Functional analysis of ten cloned NLPs demonstrated that Pc11951, Pc107869, Pc109174 and Pc118548 were capable of inducing cell death in the Solanaceae, including Nicotiana benthamiana and hot pepper. This study provides an overview of the P. capsici NLP gene family, laying a foundation for further elucidating the pathogenicity mechanism of this devastating pathogen. PMID- 29572662 TI - Clinical Pharmacokinetics of Amikacin in Pediatric Patients: A Comprehensive Review of Population Pharmacokinetic Analyses. AB - Amikacin plays a key role in the treatment of severe hospital-acquired infections with Gram-negative bacteria. Therapeutic use of amikacin is challenged by high inter-individual variability (IIV) combined with a narrow therapeutic spectrum. Pediatric patients represent a particularly fragile population where adequate dosing is crucial yet challenging to achieve due significant IIV associated with developmental processes and other factors. The current review provides an overview of parametric population pharmacokinetic analyses of amikacin in pediatric patients and associated patient-specific determinants of IIV. We searched PubMed for parametric population pharmacokinetic analyses of amikacin in pediatric patients. Information on patient population, study design, pharmacokinetic model characteristics, and identified patient-specific predictors of IIV was collected. Comparative analyses across studies were conducted to characterize quantitative differences reported for different studies and patient populations. Eight eligible publications were identified, of which six analyses involved neonates up to 3 months of age and two studies investigated older pediatric patients (age 2-17 years). Most commonly included covariates were current body weight for both clearance and volume of distribution, followed by age-related covariates on clearance in neonatal studies (four of six models). Quantitative comparisons of different models reported generally showed similar developmental effects in neonatal populations. The present review provides a comprehensive overview of parametric population pharmacokinetic studies for amikacin. Future studies could address the knowledge gap of patients between 3 months and 2 years of age. Furthermore, systematic studies of additional potential predictors for IIV (e.g., sepsis, inflammatory markers, renal function biomarkers) could be of relevance to address the significant IIV remaining after inclusion of the most commonly identified covariates. PMID- 29572663 TI - The Influence of Normalization Weight in Population Pharmacokinetic Covariate Models. AB - In covariate (sub)models of population pharmacokinetic models, most covariates are normalized to the median value; however, for body weight, normalization to 70 kg or 1 kg is often applied. In this article, we illustrate the impact of normalization weight on the precision of population clearance (CLpop) parameter estimates. The influence of normalization weight (70, 1 kg or median weight) on the precision of the CLpop estimate, expressed as relative standard error (RSE), was illustrated using data from a pharmacokinetic study in neonates with a median weight of 2.7 kg. In addition, a simulation study was performed to show the impact of normalization to 70 kg in pharmacokinetic studies with paediatric or obese patients. The RSE of the CLpop parameter estimate in the neonatal dataset was lowest with normalization to median weight (8.1%), compared with normalization to 1 kg (10.5%) or 70 kg (48.8%). Typical clearance (CL) predictions were independent of the normalization weight used. Simulations showed that the increase in RSE of the CLpop estimate with 70 kg normalization was highest in studies with a narrow weight range and a geometric mean weight away from 70 kg. When, instead of normalizing with median weight, a weight outside the observed range is used, the RSE of the CLpop estimate will be inflated, and should therefore not be used for model selection. Instead, established mathematical principles can be used to calculate the RSE of the typical CL (CLTV) at a relevant weight to evaluate the precision of CL predictions. PMID- 29572664 TI - Identification of Cytochrome P450-Mediated Drug-Drug Interactions at Risk in Cases of Gene Polymorphisms by Using a Quantitative Prediction Model. AB - BACKGROUND AND OBJECTIVE: The magnitude of drug-drug interactions mediated by cytochrome P450 (CYP) may depend on the genotype of polymorphic cytochromes. The objective of this study was to identify drug-drug interactions with greater magnitude in CYP variant groups than in extensive metabolizers. METHODS: The in vivo mechanistic static model was used to predict the area under the curve ratio of drug-drug interactions. Five cytochromes (CYP3A4/5, 2D6, 2C9, 2C19, 1A2) and five groups of genotypes for each polymorphic cytochrome (CYP2D6, 2C9, 2C19) were considered. The area under the curve ratios were calculated for all combinations and all genotypes for 196 substrates and 96 inhibitors. Among the strongest interactions (area under the curve ratio greater than 5), two levels of gene sensitivity of drug-drug interactions were defined: the intermediate sensitivity, with a three- to five-fold stronger interaction in genotype groups other than in extensive metabolizers, and the high sensitivity, with a more than five-fold stronger interaction than in genotype groups other than extensive metabolizers. RESULTS: A red list of 104 interactions with a sensitivity greater than 3, involving 13 substrates and 24 interactors was obtained. There were 59 and 45 cases of high and intermediate sensitivity, respectively. The genotypes associated with a high sensitivity were CYP2D6 *3-8 *3-8 (sensitivity up to 24.3) and CYP2C19 *2-3*2-3 (sensitivity up to 37.8). CONCLUSIONS: A cytochrome polymorphism may lead to major drug-drug interactions in poor metabolizers, while these interactions may not be significant in extensive metabolizers. Among the 104 cases studied, the interaction could be of ca. 30-fold larger magnitude in the worst case. Genotyping of the patient and/or therapeutic drug monitoring of the substrate should be carried out when an association mentioned in the red list is prescribed. The concept of gene sensitivity of drug-drug interactions appears promising for the development of precision medicine.

AB - This study employed a statistical method to obtain optimal hyper thermal acid hydrolysis conditions using Gelidium amansii (red seaweed) as a source of biomass. The optimal hyper thermal acid hydrolysis using G. amansii as biomass was determined as 12% (w/v) slurry content, 358.3 mM H2SO4, and temperature of 142.6 degrees C for 11 min. After hyper thermal acid hydrolysis, enzymatic saccharification was carried out. The total monosaccharide concentration was 45.1 g/L, 72.2% of the theoretical value of the total fermentable monosaccharides of 62.4 g/L based on 120 g dry weight/L in the G. amansii slurry. To increase ethanol production, 3.8 g/L 5-hydroxymethylfurfural (HMF) in the hydrolysate was removed by treatment with 3.5% (w/v) activated carbon for 2 min and fermented with Pichia stipitis adapted to high galactose concentrations via separate hydrolysis and fermentation. With complete HMF removal and the use of P. stipitis adapted to high galactose concentrations, 22 g/L ethanol was produced (yield 0.50). Fermentation with total HMF removal and yeast adapted to high galactose concentrations increased the fermentation performance and decreased the fermentation time from 96 to 36 h compared to traditional fermentation. PMID- 29572666 TI - Gambling and Sport: Implicit Association and Explicit Intention Among Underage Youth. AB - This study examined whether an implicit association existed between gambling and sport among underage youth in Australia, and whether this implicit association could shape their explicit intention to gamble. A sample of 14-17 year old Australian participants completed two phases of tasks, including an implicit association test based online experiment, and a post-experiment online survey. The results supported the existence of an implicit association between gambling and sport among the participants. This implicit association became stronger when they saw sport-relevant (vs. sport-irrelevant) gambling logos, or gambling relevant (vs. gambling-irrelevant) sport names. In addition, this implicit association was positively related to the amount of sport viewing, but only among those participants who had more favorable gambling attitudes. Lastly, gambling attitudes and advertising knowledge, rather than the implicit association, turned out to be significant predictors of the explicit intention to gamble.

PMID- 29572668 TI - Impact of artificial lagoons on seawater quality: evidence from 7 years of physicochemical seawater monitoring. AB - Seven years (2010-2016) of data on the basic physicochemical properties of seawater, temperature, salinity, dissolved oxygen (DO), nutrients, chlorophyll a (Chl a), and hydrocarbons from two lagoons were used to evaluate the impact of the anthropogenic activities inside the lagoon on the water quality and to explore the relationship of any impact from the lagoons' design. Statistical analysis shows the modification in water quality inside the lagoon compared to the ambient seawater is particularly evident for nitrate, silicate, and Chl a. The modification is attributed to the extensive boat activities in the lagoons and the limited water exchange between the lagoons and ambient seawater. However, the impact to both lagoons is generally limited to inside the lagoons. The oligotrophic state of the two lagoons was evaluated and it was found that the most marked code violations were found in DIN inside both lagoons. In order to explore the design importance, the water exchange and overall water quality was compared between the two lagoons. This study highlights the importance of an environmental design study before the construction of any lagoon project. Proper design would maintain acceptable water quality inside the lagoons, critical for environmental health and supporting continued recreational activities. PMID- 29572669 TI - Good glycaemic control is associated with a better prognosis in breast cancer patients with type 2 diabetes mellitus. AB - Although diabetes mellitus (DM) is one of the risk factors associated with increased breast cancer (BC) mortality, the effects of glycaemic control on the prognosis of BC have not been thoroughly evaluated. This retrospective study aimed to evaluate the relationship between glycaemic control and BC prognosis and to determine an optimal target of glycaemic control for BC patients with diabetes. We included 2812 stage 0-3 BC women, of whom 145 were diabetic and were 2667 non-diabetic. In those with diabetes, a mean haemoglobin A1C (HbA1C) < 7% (n = 77) was defined as well-controlled diabetes, while a mean HbA1C > 9% (n = 16) was defined as poorly controlled diabetes. All of the BC populations were followed from the date on which BC was diagnosed until 31 December 2015. Cox regression analysis was performed to estimate the adjusted hazards for all-cause mortality and BC-specific mortality. After controlling for the baseline and BC related confounders, the adjusted hazard ratio (HR) for all-cause mortality and the HR for BC-specific mortality were 3.65 (95% confidence interval [95% CI] 1.13 11.82) and 8.37 (95% CI 1.90-36.91), respectively, for poorly controlled diabetic women and non-DM women. However, for the diabetic women with good glycaemic control, the HRs of all-cause mortality and BC-specific mortality were not significantly different (HR 0.91, 95% CI 0.42-1.01; HR 0.77, 95% CI 0.18-3.32, respectively) from those for both mortalities in non-DM patients. For moderate controlled diabetic women, the HRs for all-cause mortality and BC-specific mortality were 1.95 (95% CI 0.89-4.27) and 3.55 (95% CI 1.369-9.30), respectively. This pilot and retrospective cohort study reveals a relationship between glycaemic control and BC prognosis in diabetic women. In addition, well controlled HbA1C, with maintained mean HbA1C values under 7%, may be associated with a better progression outcome of BC. PMID- 29572670 TI - The impact of [68Ga]PSMA I&T PET/CT on radiotherapy planning in patients with prostate cancer. AB - PURPOSE: To determine the impact of Gallium-68-labled prostate-specific membrane antigen positron-emission tomography/computed tomography ([68Ga]PSMA PET/CT) on radiotherapy planning for primary disease, biochemical cancer relapse, and advanced disease of prostate cancer. METHODS: A total of 106 patients with prostate cancer scheduled for radiation therapy underwent 120 [68Ga]PSMA PET/CT scans prior to radiotherapy treatment. In 20 cases, patients underwent [68Ga]PSMA PET/CT for primary therapy (PT), 75 cases were referred for biochemical relapse after surgery (RL), and 25 cases were intended for palliative treatment of localized metastases (MD). We retrospectively compared the impact of [68Ga]PSMA PET/CT on lesion detection and treatment decision to CT alone. RESULTS: [68Ga]PSMA PET/CT revealed a total of 271 positive lesions, whereas CT detected 86 lesions (32%). Overall, the radiotherapy regime was changed in 55 of 120 cases (46%) based on the higher detection rate of [68Ga]PSMA PET/CT: in 15% of cases with PT, in 43% of cases with RL, and in 44% of cases with MD. CONCLUSION: [68Ga]PSMA PET/CT is superior to CT alone for lesion detection in prostate cancer, thereby significantly impacting on radiotherapy planning for primary disease, biochemical cancer relapse, and advanced disease of prostate cancer. PMID- 29572671 TI - Electronic Health Information Exchange Opportunities for Self-management of Care: Responses from Older Adults With and Without Cancer History in the United States. AB - PURPOSE OF STUDY: Of 15.5 million US cancer survivors, 80% are >= 55 years. Supporting older patients in care self-management through electronic health information (EHI) exchange may enhance recovery. We assessed: (1) perceived importance of EHI access to adults >= 55 years (incl survivors) and (2) age related preferences for EHI exchange. RECENT FINDINGS: Older adults are one of the fastest-growing user groups for internet/technologies. Most older adults 55 64 years are active internet users, and use among adults >= 65 years is growing quickly as baby boomers mature. Understanding EHI patient-provider exchange preferences may provide opportunities for older patients but also begin to address the future needs of other patient populations, including cancer survivors. We observed a "digital divide" for perceived importance of EHI access and EHI exchange interests. Engaging older adults (i.e., >= 75 years) to improve comfort/experience with technologies may support EHI use in self-management. Survivors may have distinct EHI needs/preferences than older adults without cancer history. PMID- 29572672 TI - Cerebrospinal Fluid Prion Disease Biomarkers in Pre-clinical and Clinical Naturally Occurring Scrapie. AB - The analysis of the cerebrospinal fluid (CSF) biomarkers in patients with suspected prion diseases became a useful tool in diagnostic routine. Prion diseases can only be identified at clinical stages when the disease already spread throughout the brain and massive neuronal damage occurs. Consequently, the accuracy of CSF tests detecting non-symptomatic patients is unknown. Here, we aimed to investigate the usefulness of CSF-based diagnostic tests in pre-clinical and clinical naturally occurring scrapie. While decreased total prion protein (PrP) levels and positive PrP seeding activity were already detectable at pre symptomatic stages, the surrogate markers of neuronal damage total tau (tau) and 14-3-3 proteins were exclusively increased at clinical stages. The present findings confirm that alterations in PrP levels and conformation are primary events in the pathology of prion diseases preceding neuronal damage. Our work also supports the potential use of these tests in the screening of pre symptomatic scrapie and human prion disease cases. PMID- 29572673 TI - Laparoscopic anatomical liver resection after complex blunt liver trauma: a case report. AB - BACKGROUND: Various minimally invasive therapies are important adjuncts to management of hepatic injuries. However, there is a certain subset of patients who will benefit from liver resection, but there are no reports in the literature on laparoscopic anatomical liver resection for the management of complications after blunt liver trauma. CASE PRESENTATION: A 20-year-old male was admitted to the Emergency Unit of a tertiary referral center following a car accident. The patient was hemodynamically stable, and a radiologic workup demonstrated an isolated grade 3 injury of the left hemiliver. Initially, a nonoperative management was indicated, but during days following the injury, a high-volume biliary fistula complicated the clinical course. Despite percutaneous drainage, the development of devastating consequences of biliary peritonitis was imminent. A pure laparoscopic anatomical liver resection was performed. Left lateral sectionectomy eliminated the source of bile leak, and the surgery was completed with abdominal cavity lavage. Postoperative outcome was uneventful, and the patient was discharged on day 9 after injury and day 4 after surgery returning to his normal activity. CONCLUSIONS: In highly selected, hemodynamically stable patients with no other life-threatening concomitant injuries, laparoscopic liver resection in elective setting is feasible and safe for the management of complications after complex blunt trauma of the left liver. Extensive experience with hepatic surgery is needed, and surgeons should understand the increased risk they assume by taking on more complex surgical techniques. PMID- 29572675 TI - Cerebral Perforating Artery Disease : Characteristics on High-Resolution Magnetic Resonance Imaging. AB - PURPOSE: Our aims were to evaluate the feasibility of high-resolution magnetic resonance imaging (HR-MRI) for displaying the cerebral perforating arteries in normal subjects and to discuss the value of HR-MRI for detecting the causes of infarctions in the territory of the lenticulostriate artery (LSA). METHODS: Included in this study were 31 healthy subjects and 28 patients who had infarctions in the territory supplied by the LSA. The T1-weighted imaging (T1WI), T2WI, diffusion-weighted imaging (DWI), and HR-MRI, including 3-dimensional time of-flight magnetic resonance angiography (3D-TOF-MRA) and 3D fast spin-echo T1WI (namely CUBE T1 in GE Healthcare), were applied on a 3-Tesla scanner. The numbers and route of the perforating arteries on both sides were independently confirmed on HR-MRI by two physicians. The Wilcoxon test was used to compare the differences. RESULTS: The numbers of perforating arteries in healthy subjects observed on 3D-TOF-MRA were as follows: numbers of the bilateral recurrent artery of Heubner (RAH) ranged from 0-3 (median 1), numbers of the left LSA ranged from 0-7 (median 3), numbers of the right LSA ranged from 0-5 (median 3), numbers of the bilateral anterior choroidal artery ranged from 1-2 (median 1) and the numbers of the bilateral thalamoperforating artery ranged from 1-2 (median 1). In the patients with lenticulostriate infarctions, the numbers of LSAs on the affected side were lower than on the opposite and ipsilateral sides in the healthy subjects. The results were statistically significant. An abnormality of the RAH may lead to a centrum semiovale infarct pattern, whereas an abnormality of the LSA is associated with a corona radiata infarct pattern. CONCLUSION: The use of HR 3D-TOF-MRA and CUBE T1 had unique advantages in displaying the tiny perforating arteries in vivo. Moreover, effective recognition of the associated cerebral perforating artery and infarct patterns may enhance our understanding of the mechanism of stroke in patients with lenticulostriate infarctions. PMID- 29572674 TI - Multi-institutional study of treatment patterns in Korean patients with WHO grade II gliomas: KNOG 15-02 and KROG 16-04 intergroup study. AB - INTRODUCTION: We performed this study to identify the treatment patterns of patients with low-grade gliomas (LGG) in Korea. METHODS: A total of 555 patients diagnosed as WHO grade II gliomas between 2000 and 2010 at 14 Korean institutions were included. The patients were divided into four adjuvant treatment groups: adjuvant fractionated radiotherapy (RT, N = 204), adjuvant chemotherapy (N = 20), adjuvant fractionated RT and chemotherapy (N = 65), and non-adjuvant treatment (N = 266) groups. We examined differences among the groups and validated patient/tumor characteristics associated with the adjuvant treatments. RESULTS: Astrocytoma was diagnosed in 210 patients (38%), oligoastrocytoma in 85 patients (15%), and oligodendroglioma in 260 patients (47%). Gross total resection was performed in 200 patients (36%), subtotal resection in 153 (28%), partial resection in 71 patients (13%), and biopsy in 131 patients (24%). RT was most commonly applied as an adjuvant treatment. The use of chemotherapy with or without RT decreased after 2008 (from 38 to 4%). The major chemotherapeutic regimen was procarbazine, lomustine, and vincristine (PCV); however, the proportion of temozolomide increased since 2005 (up to 69%). Patient/tumor characteristics related with RT were male gender, non-seizure, multiple lobes involvement, and non-gross total resection. Chemotherapy was associated with non gross total resection and non-astrocytoma. CONCLUSIONS: A preference for RT and increased use of temozolomide was evident in the treatment pattern of LGG. The extent of resection was associated with a decision to perform RT and chemotherapy. To establish a robust guideline for LGG, further studies including molecular information are needed. PMID- 29572676 TI - Winter cholecalciferol supplementation at 55 degrees N has little effect on markers of innate immune defense in healthy children aged 4-8 years: a secondary analysis from a randomized controlled trial. AB - PURPOSE: We explored the effect of winter cholecalciferol (vitamin D3) supplementation on innate immune markers in healthy Danish children (55 degrees N). METHODS: In the double-blind, placebo-controlled trial, ODIN Junior, 119 healthy, white, 4-8 year-olds were randomized to 0 (placebo), 10 or 20 ug/day of vitamin D3 for 20 weeks (October-March). Cheek mucosal swabs, blood samples, and questionnaires on acute respiratory infections the previous month were collected at baseline and endpoint. Innate immune markers were measured as secondary outcomes including in vivo oral mucosal gene expression of calprotectin (S100A9), lipocalin-2 (LCN2), beta-defensin-4 (DEFB4), interleukin-8 (IL-8), viperin (RSAD2), and the cathelicidin-antimicrobial-peptide (CAMP); ex vivo whole-blood lipopolysaccharide (LPS)-induced cathelicidin, IL-8, and IL-6; and plasma cathelicidin, together with serum 25-hydroxyvitamin D [25(OH)D]. RESULTS: Serum 25(OH)D was 56.7 +/- 12.3 nmol/L at baseline and 31.1 +/- 7.5, 61.8 +/- 10.6, and 75.8 +/- 11.5 nmol/L at endpoint after placebo, 10 and 20 ug/day of vitamin D3 (P < 0.0001), respectively. A decreased oral mucosal S100A9 expression with placebo [- 18 (95% CI - 1; - 32)%] was marginally avoided with 20 ug/day [6 (- 13; 28)%] (P = 0.06). Likewise, a decreased LPS-induced IL-8 with placebo [- 438 (95% CI - 693; - 184) ng/L] was marginally avoided with 20 ug/day [- 109 (- 374; 157) ng/L] (P = 0.07). All other immune markers and respiratory infection episodes were unaffected by vitamin D3 supplementation (all P > 0.11). CONCLUSIONS: Winter vitamin D3 supplementation of 10 ug/day did not affect innate immune markers, whereas 20 ug/day tended to maintain the capacity to produce a few markers in healthy children. PMID- 29572678 TI - Perspective on Broad-Acting Clinical Physiological Effects of Photobiomodulation. AB - Research into photobiomodulation reveals beneficial effects of light therapy for a rapidly expanding list of medical conditions and illnesses. Although it has become more widely accepted by the mainstream medicine, the effects and mechanisms of action appear to be poorly understood. The therapeutic benefits of photobiomodulation using low-energy red lasers extend far beyond superficial applications, with a well-described physics allowing an understanding of how red lasers of certain optimum intensities may cross the cranium. We now have a model for explaining potential therapeusis for applications in functional neurology that include stroke, traumatic brain injury, and neurodegenerative conditions in addition to the currently approved functions in lipolysis, in onychomycosis treatment, and in pain management. PMID- 29572677 TI - A qualitative transcriptional signature to reclassify estrogen receptor status of breast cancer patients. AB - PURPOSE: Immunohistochemistry (IHC) assessment of the estrogen receptor (ER) status has low consensus among pathologists. Quantitative transcriptional signatures are highly sensitive to the measurement variation and sample quality. Here, we developed a robust qualitative signature, based on within-sample relative expression orderings (REOs) of genes, to reclassify ER status. METHODS: From the gene pairs with significantly stable REOs in ER+ samples and reversely stable REOs in ER- samples, concordantly identified from four datasets, we extracted a signature to determine a sample's ER status through evaluating whether the REOs within the sample significantly match with the ER+ REOs or the ER- REOs. RESULTS: A signature with 112 gene pairs was extracted. It was validated through evaluating whether the reclassified ER+ or ER- patients could benefit from tamoxifen therapy or neoadjuvant chemotherapy. In three datasets for IHC-determined ER+ patients treated with post-operative tamoxifen therapy, 11.6 12.4% patients were reclassified as ER- by the signature and, as expected, they had significantly worse recurrence-free survival than the ER+ patients confirmed by the signature. On another hand, in two datasets for IHC-determined ER- patients treated with neoadjuvant chemotherapy, 18.8 and 7.8% patients were reclassified as ER+ and, as expected, their pathological complete response rate was significantly lower than that of the other ER- patients confirmed by the signature. CONCLUSIONS: The REO-based signature can provide an objective assessment of ER status of breast cancer patients and effectively reduce misjudgments of ER status by IHC. PMID- 29572679 TI - Copeptin Blood Content as a Diagnostic Marker of Chronic Kidney Disease. AB - Plasma content of copeptin increases with the advancement of chronic kidney disease (CKD). The purpose of this study was to evaluate copeptin content as a potential marker of CKD, as a single pathology or with coexisting heart failure. Seventy-six patients were divided into the following groups: Group 1 (control), without CKD and heart failure; Group 2, CKD stage 3a; Group 3, CKD stage 3b; Group 4, CKD stage 4; Group 5, CKD stage 5; and Group 6, CKD stage 3b and heart failure. For all patients, plasma concentrations of copeptin, creatinine, urea, cystatin C, sodium, C-reactive protein (CRP), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), and blood pH were assessed. We found that plasma content of creatinine, urea, CRP, cystatin, NT-proBNP, and copeptin increased with CKD progression. Heart failure in CKD patients was not the cause of an appreciable increase of copeptin level. Copeptin/creatinine, copeptin/cystatin C ratios, and especially copeptin/eGFR ratio enhanced copeptin prognostic sensitivity concerning renal failure in CKD, compared with copeptin alone. The copeptin*NT-proBNP ratio decreased along CKD progression, reaching a nadir in the accompanying heart failure. In contradistinction, copeptin*NT-proBNP/creatinine ratio increased along CKD progression, reaching a peak in the accompanying heart failure. We conclude that copeptin is an important marker in CKD, but not so concerning heart failure in the disease. A decrease in copeptin*NT-proBNP and an increase in copeptin*NT-proBNP/creatinine ratio are useful markers of cardiac function decline in CKD. PMID- 29572680 TI - SYNTAX Score and Outcomes of Coronary Revascularization in Diabetic Patients. AB - PURPOSE OF REVIEW: This review describes the dynamic relationship between diabetes mellitus (DM) and coronary artery disease (CAD) with respect to different revascularization strategies and how angiographic tools such as the Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score can supplement clinical decision-making. RECENT FINDINGS: The SYNTAX score characterizes the anatomical extent of CAD in terms of the number of lesions, functional importance, and complexity. Studies not limited to patients with DM suggest that percutaneous coronary intervention (PCI) is a reasonable alternative to coronary artery bypass grafting (CABG) in patients with low-medium SYNTAX scores, while patients with high SYNTAX scores should be revascularized with CABG if operable. Similar findings were also observed for diabetes patients with multivessel disease in retrospective pooled analysis. The SYNTAX II score combines anatomical and clinical risk to improve upon the decision regarding the optimal revascularization strategy. The SYNTAX II score can be applied to patients with DM. The SYNTAX scores provide guidance to clinicians faced with determining the optimal revascularization strategy in patients with DM and advanced CAD. Using a heart team approach, the information can be considered along with other factors that influence PCI or CABG risk. PMID- 29572681 TI - HIV and the Macrophage: From Cell Reservoirs to Drug Delivery to Viral Eradication. AB - Macrophages serve as host cells, inflammatory disease drivers and drug runners for human immunodeficiency virus infection and treatments. Low-level viral persistence continues in these cells in the absence of macrophage death. However, the cellular microenvironment changes as a consequence of viral infection with aberrant production of pro-inflammatory factors and promotion of oxidative stress. These herald viral spread from macrophages to neighboring CD4+ T cells and end organ damage. Virus replicates in tissue reservoir sites that include the nervous, pulmonary, cardiovascular, gut, and renal organs. However, each of these events are held in check by antiretroviral therapy. A hidden and often overlooked resource of the macrophage rests in its high cytoplasmic nuclear ratios that allow the cell to sense its environment and rid it of the cellular waste products and microbial pathogens it encounters. These phagocytic and intracellular killing sensing mechanisms can also be used in service as macrophages serve as cellular carriage depots for antiretroviral nanoparticles and are able to deliver medicines to infectious disease sites with improved therapeutic outcomes. These undiscovered cellular functions can lead to reductions in persistent infection and may potentially facilitate the eradication of residual virus to eliminate disease. PMID- 29572682 TI - The inhibitory effect of sodium baicalin on oseltamivir-resistant influenza A virus via reduction of neuraminidase activity. AB - Baicalin was identified as a neuraminidase (NA) inhibitor displaying anti influenza A virus (IAV) activity. However, its poor solubility in saline has limited its use in the clinic. We generated sodium baicalin and showed that it exhibited greatly increased solubility in saline. Its efficacy against oseltamivir-resistant mutant A/FM/1/47-H275Y (H1N1-H275Y) was evaluated in vitro and in vivo. Results showed that 10 MUM of sodium baicalin inhibited A/FM/1/47 (H1N1), A/Beijing/32/92 (H3N2) and H1N1-H275Y in MDCK cells in a dose-dependent manner, with inhibitory rates of 83.9, 75.9 and 47.7%, respectively. Intravenous administration of sodium baicalin at 100 mg/kg/d enabled the survival of 20% of H1N1-H275Y-infected mice. The treatment alleviated body weight loss and lung injury. Moreover, sodium baicalin exerted a clear inhibitory effect on NAs. The IC50 values of sodium baicalin against H1N1-H275Y and cells-expressing A/Anhui/1/2013-R294K (H7N9-R294K) NA protein (N9-R294K) were 214.4 MUM and 216.3 MUM. Direct interactions between sodium baicalin and NA were observed, and we simulated the interactions of sodium baicalin with N9-R294K and N9 near the active sites of OC-N9-R294K and OC-N9. The residues responsible for the sodium baicalin-N9-R294K and sodium baicalin-N9 interactions were the same, confirming that sodium baicalin exerts effects on wild-type and oseltamivir-resistant viral strains. PMID- 29572683 TI - Analysis of loxoprofen in tablets, patches, and equine urine as tert butyldimethylsilyl derivative by gas chromatography-mass spectrometry. AB - Loxoprofen is a non-steroidal anti-inflammatory drug of the 2-arylpropionic acid type, which has used to treat musculoskeletal disorders in the horse racing industry. However, it has also used illicitly to mask clinical signs of inflammation and pain in racehorses. Thus, its accurate analysis has become an important issue in horse doping laboratories. In this study, an analytical method of loxoprofen was developed as tert-butyldimethylsilyl (TBDMS) derivative by gas chromatography-mass spectrometry (GC-MS). Characteristic fragment ions of [M-15], [M-57], and [M-139] permitted the accurate and selective detection of loxoprofen. Under optimal conditions, this method showed good linearity (r >= 0.999) in the range of 10-500 ng/mL, repeatability (% relative standard deviation = 5.6-8.5), and accuracy (% relative error = - 0.3-0.9) with a detection limit of 1.0 ng. When applied to the analysis of loxoprofen in tablet and patch products, loxoprofen was positively identified as TBDMS derivative by GC-MS. The present method provided rapid and accurate determination of loxoprofen in patch and tablet products. Levels of loxoprofen were highest in equine urine at 0.5 and 1 h after oral administration with single dose (3 mg/kg) to three horses, and then rapidly reduced to below the lower limit of quantification at 24 h. Therefore, the present method will be useful for the pharmacokinetic study and doping tests for loxoprofen and other similar acidic drugs in horses. PMID- 29572684 TI - Preliminary assessment of groundwater hydrogeochemistry within Gilan, a northern province of Iran. AB - In four basins of Gilan province, groundwater samples were collected from 127 piezometric wells to investigate the hydrogeochemistry of groundwater, and additionally its suitability for drinking and irrigation purposes. The average concentrations of major cations and anions follow the order of Ca2+ > Na+ > Mg2+ > K+ and [Formula: see text], respectively. Using Piper diagram delineation, CaMgHCO3 was determined as the main hydrogeochemical facies of groundwater. According to Piper diagrams, Gibbs plots, and ionic ratios, silicate weathering and ion exchange are the major processes regulating the groundwater hydrochemistry. Furthermore, saturation indices (SIs) revealed that carbonate precipitation also plays an important role in aquifers. Among the processes, weathering of silicate minerals seems to be the dominant process. Comparing the analyzed major ions and physicochemical parameters with the WHO guideline values indicates that the potability of most groundwater samples is generally acceptable. Electrical conductivity (EC) and total dissolved solid (TDS) measurements along with sodium percentage (SP), sodium adsorption ratio (SAR), Kelley's index (KI), and residual sodium carbonate (RSC) calculations suggest that groundwater in many areas is suitable for irrigation use. Nonetheless, total hardness (TH) values ranging as high as 650.0 mg/l reveal many groundwater samples to be classified as hard and very hard, indicating a requirement for long term monitoring and further evaluation. The present study shows that the groundwater quality in Lahijan, Astaneh, and to a lesser extent Fouman drainage basins is lower than in Talesh. Therefore, intense monitoring programs towards enhanced water management practices are recommended before poorer quality groundwater is further utilized.

PMID- 29572687 TI - Biocompatibility and biomineralization assessment of mineral trioxide aggregate flow. AB - OBJECTIVE: Evaluate, in vivo, the biocompatibility via subcutaneous inflammatory tissue response and mineralization ability of the new MTA Flow compared to MTA Angelus and ProRoot MTA. MATERIALS AND METHODS: Forty male Wistar rats were assigned and received subcutaneous polyethylene tube implants containing the test materials and a control group with empty tube (n = 10 animals/group). After days 7, 15, 30, and 60, the animals were euthanized and the polyethylene tubes were removed with the surrounding tissues. Inflammatory infiltrate and thickness of the fibrous capsule were histologically evaluated. Mineralization was analyzed by Von Kossa staining and under polarized light. Data were analyzed via Kruskal Wallis and Dunn's test with a significance level of 5%. RESULTS: MTA Angelus induced the mildest reaction after 7 (P > .05) and 15 days (P < .05) followed by MTA Flow, both cements achieving mild inflammatory reaction after 15 days. ProRoot MTA induced a severe inflammation on day 7 and was reducing after day 15 (P > .05). No difference was observed after days 30 or 60 (P > .05). Von Kossa staining and birefringent structures were positive to all materials. CONCLUSIONS: At the end of the experiment, the novel MTA Flow showed biocompatibility and induced biomineralization in all time periods. CLINICAL RELEVANCE: The final consistence obtained in MTA Flow may facilitate several procedures, indicating that the MTA Flow has a promising application in endodontics. PMID- 29572686 TI - Anatomical locations in the oral cavity where surgical resections of oral squamous cell carcinomas are associated with a close or positive margin-a retrospective study. AB - OBJECTIVES: This study aimed to identify anatomical areas where resections of oral squamous cell carcinomas (OSCC) are significantly associated with close or positive margins. MATERIALS AND METHODS: This retrospective study included 330 patients with a primary OSCC from 2010 to 2015. Patient and tumour data were categorised into three groups by R-status (R0 [clear], >= 5 mm, 185 patients [56.06%]; R1 [positive], < 1 mm, 24 patients [7.27%]; and R0 [close], 1-5 mm, 121 patients [36.67%]). RESULTS: Areas where resections were significantly associated with close or positive margins were the hard palate (p < 0.001), buccal mucosa (p = 0.03), floor of the mouth (p = 0.004), lower alveolar ridge (p = 0.01), retromolar triangle (p = 0.005), and dorsal tongue (p = 0.02). CONCLUSIONS: Anatomical areas were identified in the oral cavity where it is challenging to resect OSCCs with an adequate safety margin. CLINICAL RELEVANCE: These results may enable surgeons to achieve a postulated safe distance during tumour resection, leading to a survival benefit for patients. PMID- 29572688 TI - Periodontal and endodontic infectious/inflammatory profile in primary periodontal lesions with secondary endodontic involvement after a calcium hydroxide-based intracanal medication. AB - OBJECTIVE: The aim of the present study was to investigate the effects of a calcium hydroxide-based intracanal medication (ICM) on periodontal and endodontic infectious/inflammatory contents and on periodontal clinical parameters in teeth with primary periodontal lesion and secondary endodontic involvement. MATERIALS AND METHODS: Ten patients with abnormal pulp test results and deep probing depth derived from primary periodontal disease with secondary endodontic involvement were included. Samples were collected from root canals (RC) and periodontal pockets (PP) in order to investigate the microbiological status, levels of endotoxin (LPS), cytokines, and matrix metalloproteinases (MMP), before and after ICM. PCR was used for microbiological assessment. The kinetic-chromogenic LAL assay was used for LPS quantification. Quantikine ELISA kits were used for measurement of IL-1 alpha, IL-1 beta, TNF-alpha, PGE2, MMP-2, MMP-3, MMP-8, MMP 9, and MMP-13 levels. The statistical analyses were made using the Friedman and Wilcoxon tests (p < 0.05). T test was used to compare data on periodontal characteristics. RESULTS: ICM did not reduce the number of microorganisms in PP and RC, except for Fusobacterium nucleatum in RC. There was a significant reduction in LPS, MMPs, IL-1 beta, and TNF-alpha levels in PP after ICM. In RC, LPS, MMP13, PGE2, and IL-1beta levels remained unaltered (p > 0.05); however, the levels of the other MMPs and cytokines were reduced (p < 0.05). After 1 year of the root canal treatment, tooth mobility was significantly reduced (p <= 0.05). CONCLUSIONS: The use of a calcium hydroxide-based ICM showed positive effects for periodontal treatment prognosis, as it reduced LPS, cytokine, and MMP levels in periodontal pockets. CLINICAL SIGNIFICANCE: Patients presenting deep probing depth and undergoing periodontal treatment for at least 6 months, with no positive response to periodontal therapy, might benefit with the endodontic treatment. PMID- 29572689 TI - Assessing the effects of different agro-residue as substrates on growth cycle and yield of Grifola frondosa and statistical optimization of substrate components using simplex-lattice design. AB - Grifola frondosa is an economically important edible and medicinal mushroom usually produced on substrate consisting of sawdust supplemented with wheat bran. Cultivation of G. frondosa on crop straw (corn cob, corn straw, rice straw, and soybean straw) as a substrate was optimized by using the D-optimum method of the simplex-lattice design, and the alternative of crop straw as a substitute for sawdust in the substrate composition was determined by the optimized model. The results showed that there was a significant positive correlation existing between the yield and corn cob. The growth cycle was negatively correlated with sawdust, corn cob and soybean straw, with sawdust significantly shortening the growth cycle of G. frondosa. The optimized high-yielding formula included 73.125% corn cob, 1.875% rice straw, 23% wheat bran and 2% light calcium carbonate (CaCO3) (C/N = 48.40). The average yield of the first flush was 134.72 +/- 4.24 g/bag, which was increased by 39.97% compared with the control formula. The biological efficiency (BE) was 44.91 +/- 1.41%, which was increased by 38.53% compared with the control. Based on the results of this study, corn cob can replace sawdust as one of the main cultivation substrates of G. frondosa. PMID- 29572690 TI - Human Ischaemic Cascade Studies Using SH-SY5Y Cells: a Systematic Review and Meta Analysis. AB - Low translational yield for stroke may reflect the focus of discovery science on rodents rather than humans. Just how little is known about human neuronal ischaemic responses is confirmed by systematic review and meta-analysis revealing that data for the most commonly used SH-SY5Y human cells comprises only 84 papers. Oxygen-glucose deprivation, H2O2, hypoxia, glucose-deprivation and glutamate excitotoxicity yielded - 58, - 61, - 29, - 45 and - 49% injury, respectively, with a dose-response relationship found only for H2O2 injury (R2 = 29.29%, p < 0.002). Heterogeneity (I2 = 99.36%, df = 132, p < 0.0001) was largely attributable to the methods used to detect injury (R2 = 44.77%, p < 0.000) with cell death assays detecting greater injury than survival assays (- 71 vs - 47%, R2 = 28.64%, p < 0.000). Seventy-four percent of publications provided no description of differentiation status, but in the 26% that did, undifferentiated cells were susceptible to greater injury (R2 = 4.13%, p < 0.047). One hundred and sixty-nine interventions improved average survival by 34.67% (p < 0.0001). Eighty eight comparisons using oxygen-glucose deprivation found both benefit and harm, but studies using glutamate and H2O2 injury reported only improvement. In studies using glucose deprivation, intervention generally worsened outcome. There was insufficient data to rank individual interventions, but of the studies reporting greatest improvement (> 90% effect size), 7/13 were of herbal medicine constituents (24.85% of the intervention dataset). We conclude that surprisingly little is known of the human neuronal response to ischaemic injury, and that the large impact of methodology on outcome indicates that further model validation is required. Lack of evidence for randomisation, blinding or power analysis suggests that the intervention data is at substantial risk of bias. PMID- 29572692 TI - An extension of the Marcus equation: the Marcus potential energy function. AB - An analytic potential function consistent with the Marcus equation for activation energy is formulated and used to reveal new insights into the activation process in chemical reactions. As for the Marcus equation, the new potential function depends only on two parameters, the reaction energy and the activation energy (or the so-called Marcus intrinsic activation energy). Combination of the Marcus potential with the reaction force analysis provides two-parameter analytic expressions for the reaction force, reaction force constant, and reaction works. Moreover, since the parameters necessary to define the Marcus potential energy function can be obtained experimentally, the present model may produce experimental analytic potentials allowing for new and interesting applications, thus emerging as a powerful tool to characterize activation processes in chemical reactions. PMID- 29572691 TI - Fluoroquinolone Restriction as an Effective Antimicrobial Stewardship Intervention. AB - PURPOSE OF REVIEW: Fluoroquinolones are a commonly prescribed antibiotic class that has come under scrutiny in recent years due to mounting evidence of association between adverse drug events, C. difficile infection and isolation of antibiotic-resistant bacteria. RECENT FINDINGS: Inpatient antimicrobial stewardship (AMS) programs have a toolbox of potential interventions to curb inappropriate antibiotic use, prevent antibiotic-associated adverse drug events, and avoid unnecessary costs of care. Fluoroquinolone restriction policies in the acute care setting have demonstrated beneficial effects, including decreased rates of C. difficile infection and ESBL-producing Enterobacteriaceae. However, a simple blanket restriction policy may "squeeze the antibiotic balloon" and will likely be insufficient if not implemented in conjunction with other AMS interventions. There is a growing body of evidence to support formulary restriction of fluoroquinolones in the acute care setting to decrease rates of C. difficile infection and development of ESBL-producing organisms. Data on how to best implement these restrictions or how to implement outside of acute care settings is limited. PMID- 29572693 TI - Human chorionic gonadotropin serum levels following ovulation triggering and IVF cycle outcome. AB - PURPOSE: The clinical significance of serum hCG levels after ovulation triggering was studied previously with conflicting results. Our aim was to study the correlation of hCG levels on the day after ovulation triggering using recombinant hCG (r-hCG) with treatment outcome. METHODS: A prospective observational study of all fresh IVF/ICSI cycles in a single medical center, between January 2015 and June 2016, was performed. hCG serum levels were obtained 10-12 h following ovulation triggering with 250 mcg r-hCG. Clinical and laboratory outcome parameters were compared between cycles with serum hCG above and below median level. A multivariate regression analysis was performed in order to study the association between hCG levels and live birth rate, after controlling for confounders. RESULTS: Overall, 326 cycles were included. Median serum hCG level was 91.35 IU/L. hCG levels were lower as age and BMI were higher (p = 0.004, p < 0.001, respectively). The study groups did not differ with regard to clinical pregnancy rate (p = 0.14), live birth rate (p = 0.09), fertilization rate (p = 0.45), or metaphase II oocyte rate (p = 0.68). On multivariate regression analysis, hCG level was not associated with live birth (aOR 0.99, 95% CI 0.98 1.005), after controlling for patient's age and BMI. CONCLUSIONS: hCG levels on the day after ovulation triggering with 250 mcg r-hCG are inversely correlated with patient age and BMI. However, they are not correlated with any clinical or laboratory outcome parameter. Therefore, testing for hCG levels after ovulation induction seems futile and cannot be recommended. PMID- 29572694 TI - Total urokinase-type plasminogen activator (uPA) levels in seminal plasma are associated with positive assisted reproductive technology outcomes. AB - PURPOSE: The plasminogen/plasmin system is an important extracellular protease system whose function has been implicated in male reproductive function. However, its clinical relevance to fertility in human assisted reproduction technologies has not been systematically investigated. Here, we examined whether total and active populations of urokinase-type plasminogen activator (uPA) in human seminal plasma and spermatozoa are predictive of pregnancy outcome in couples undergoing insemination or intracytoplasmic sperm injection (ICSI). METHODS: Seminal samples from 182 men, 5 donors, 21 patients attending the clinic for infertility screening, and 156 for assisted reproduction technology (ART) treatment (insemination and ICSI), were evaluated. Total uPA in seminal plasma and spermatozoa as well as active uPA in seminal plasma were measured by ELISA. Sperm quality parameters and fertility outcomes following insemination or ICSI were correlated with the uPA values. RESULTS: Active uPA in seminal plasma was positively correlated to the volume of the ejaculate, total number of spermatozoa in the ejaculate, and total motility. However, these values were not prognostic of fertility outcomes. Total uPA in spermatozoa was inversely related to sperm concentration, total sperm in ejaculate, morphology, and total and progressive motility, and this measure was not related to fertility. Importantly, however, higher values of total uPA in seminal plasma were detected in cases that resulted in pregnancy compared to those that did not follow insemination and ICSI treatment. CONCLUSIONS: Taken together, these findings lay the foundation for further understanding the mechanism by which total uPA in seminal plasma affects fertility and how this marker can be used as a predictor of ART outcomes. PMID- 29572695 TI - The effect of swim-up and gradient sperm preparation techniques on deoxyribonucleic acid (DNA) fragmentation in subfertile patients. AB - PURPOSE: To compare the effect of two different sperm preparation techniques, including swim-up and gradient methods on sperm deoxyribonucleic acid (DNA) fragmentation status of semen samples from unexplained and mild male factor subfertile patients undergoing intrauterine insemination (IUI). DESIGN: A prospective randomized study was conducted in 65 subfertile patients, including 34 unexplained and 31 male factor infertility to compare basal and post-procedure DNA fragmentation rates in swim-up and gradient techniques. Sperm DNA fragmentation rates were evaluated by a sperm chromatin dispersion (SCD) test in two portions of each sample of semen that was prepared with either swim-up or gradient techniques. Sperm motility and morphology were also assessed based on WHO 2010 criteria. RESULTS: Swim-up but not gradient method yielded a statistically significant reduction in the DNA fragmented sperm rate after preparation as compared to basal rates, in the semen samples of both unexplained (41.85 +/- 22.04 vs. 28.58 +/- 21.93, p < 0.001 for swim-up; and 41.85 +/- 22.04 vs. 38.79 +/- 22.30, p = 0.160 for gradient) and mild male factor (46.61 +/- 19.38 vs. 30.32 +/- 18.20, p < 0.001 for swim-up and 46.61 +/- 19.38 vs. 44.03 +/ 20.87, p = 0.470 for gradient) subgroups. CONCLUSIONS: Swim-up method significantly reduces sperm DNA fragmentation rates and may have some prognostic value on intrauterine insemination in patients with decreased sperm DNA integrity.

AB - The Natal multimammate mouse (Mastomys natalensis) is the reservoir host of Lassa arenavirus, the etiological agent of Lassa fever in humans. Because there exists no vaccine for human use, rodent control and adjusting human behavior are currently considered to be the only options for Lassa fever control. In order to develop efficient rodent control programs, more information about the host's ecology is needed. In this study, we investigated the spatial behavior of M. natalensis and other small rodents in two capture-mark-recapture and four dyed bait (Rhodamine B) experiments in Lassa fever-endemic villages in Upper Guinea. During the capture-mark-recapture studies, 23% of the recaptured M. natalensis moved between the houses and proximate fields. While M. natalensis was found over the entire study grid (2 ha), other rodent species (Praomys daltoni, Praomys rostratus, Lemniscomys striatus, Mus spp.) were mostly trapped in the surrounding fields. Distances between recapture occasions never exceeded 100 m for all rodent species. During the dyed bait experiments, 11% of M. natalensis and 41% of P. daltoni moved from the fields to houses. We conclude that commensal M. natalensis easily moves between houses and proximate fields in Guinea. We therefore consider occasional domestic rodent elimination to be an unsustainable approach to reduce Lassa virus transmission risk to humans, as M. natalensis is likely to reinvade houses quickly from fields in which rodents are not controlled. A combination of permanent rodent elimination with other control strategies (e.g., make houses rodent proof or attract predators) could be more effective for Lassa fever control, but must be further investigated. PMID- 29572696 TI - Endoscopic Management of Difficult Bile Duct Stones. AB - PURPOSE OF REVIEW: In 10-15% of the cases, conventional methods for removing bile duct stones by ERCP/balloon-basket extraction fail. The purpose of this review is to describe endoscopic techniques in managing these "difficult bile duct stones." RECENT FINDINGS: Endoscopic papillary large balloon dilation with balloon extraction +/- mechanical lithotripsy is the initial approach used to retrieve large bile duct stones. With advent of digital cholangioscopy, electrohydraulic and laser lithotripsy are gaining popularity. Enteroscopy-assisted or laparoscopic-assisted approaches can be used for those with gastric bypass anatomy. Difficulties in removing bile duct stones can be related to stone related factors such as the size and location of the stone or to altered anatomy such as stricture in the bile duct or Roux-en-Y anatomy. Several endoscopy approaches and techniques have described in the recent past that have greatly enhanced our ability to remove these "difficult" bile duct stones.

AB - We developed a method for differential diagnosis of nymphs and larvae of sheep (Ixodes ricinus (L.)) and taiga (I. persulcatus Sch.) ticks (Parasitiformes: Ixodidae) which allows to identify live material in the field. PMID- 29572700 TI - Impact of the erineum strain of Colomerus vitis (Acari: Eriophyidae) on the development of plants of grapevine cultivars of Iran. AB - The present experiment was aimed at determining the influence of the grape erineum strain of Colomerus vitis (GEM) (Acari: Eriophyidae) on responses of local grapevine cultivars. GEM was applied at five density levels to each of five cultivars, i.e. Shahani, Sahebi Uroomie, Khalili Bovanat, Rishbaba and Sezdang Ghalat (listed from early to late grape ripening). The experiment was performed in a full factorial design (12 replicates each) and effects of the mite on the relative content of leaf chlorophyll, internode and cane length, leaf area and weight, number and size of the erinea, and percentage of leaves with erinea were investigated. Also mite density on leaves and in buds was assessed. Data were analyzed with a two-way ANOVA followed by Tukey's test to separate means among treatment levels and cultivars. The relative content of chlorophyll (expressed in Spad units) in infested leaves was reduced along with an increase in mite density and it was shown to be highly significant at the two higher mite density levels for Khalili Bovanat, Rishbaba and Sezdang Ghalat; Shahani and Sahebi Uroomie leaves appeared to be less affected by mite infestation. The highest mite density treatment displayed a strong correlation with weight (positive correlation) and size (negative correlation) of the leaves of four cultivars; leaves of Sahebi Uroomie appeared to be less affected. The reduced internode length was weak in infested plants. Most infested plants produced shorter canes and their lengths appeared to have a strong negative correlation with the highest mite density in four cultivars; canes of Sahebi Uroomie did not appear affected. At the highest mite density, canes of Khalili Bovanat and Sahebi Uroomie displayed the most and the least shortening effects, respectively. The percentage of leaves with erinea, as well as the number of erinea per leaves and the diameter of erinea increased along with the mite population density. The mite densities in buds (April 2014) and on leaves with erinea (in November 2013) were higher at the highest treatment level in the medium-late (Rishbaba) and late ripening (Sezdang Ghalat) cultivars, than in the early and early-medium ripening ones. Almost all data collected in the current experiment allowed the conclusion that Sahebi Uroomie and Shahani were less affected than the other cultivars (Khalili Bovanat, Rishbaba and Sezdang Ghalat). PMID- 29572701 TI - Diacylglycerol kinase alpha inactivation is an integral component of the costimulatory pathway that amplifies TCR signals. AB - The arsenal of cancer therapies has evolved to target T lymphocytes and restore their capacity to destroy tumor cells. T cells rely on diacylglycerol (DAG) to carry out their functions. DAG availability and signaling are regulated by the enzymes diacylglycerol kinase (DGK) alpha and zeta, whose excess function drives T cells into hyporesponsive states. Targeting DGKalpha is a promising strategy for coping with cancer; its blockade could reinstate T-cell attack on tumors while limiting tumor growth, due to positive DGKalpha functions in several oncogenic pathways. Here, we made a side-by-side comparison of the effects of commercial pharmacological DGK inhibitors on T-cell responses with those promoted by DGKalpha and DGKzeta genetic deletion or silencing. We show the specificity for DGKalpha of DGK inhibitors I and II and the structurally similar compound ritanserin. Inhibitor treatment promoted Ras/ERK (extracellular signal-regulated kinase) signaling and AP-1 (Activator protein-1) transcription, facilitated DGKalpha membrane localization, reduced the requirement for costimulation, and cooperated with enhanced activation following DGKzeta silencing/deletion. DGKiII and ritanserin had similar effects on TCR proximal signaling, but ritanserin counteracted long-term T-cell activation, an effect that was potentiated in DGKalpha-/- cells. In contrast with enhanced activation triggered by pharmacological inhibition, DGKalpha silencing/genetic deletion led to impaired Lck (lymphocyte-specific protein tyrosine kinase) activation and limited costimulation responses. Our results demonstrate that pharmacological inhibition of DGKalpha downstream of the TCR provides a gain-of-function effect that amplifies the DAG-dependent signaling cascade, an ability that could be exploited therapeutically to reinvigorate T cells to attack tumors. PMID- 29572703 TI - Using a Small Cash Incentive to Increase Survey Response. AB - Surveys tend to yield low response rates among human service professionals. This study examined whether a randomly-assigned prepaid $2 incentive increased response rates over time, and was cost-effective for increasing response count, among social workers and volunteer mediators. The incentive was enclosed with a mixed-mode survey of factors related to burnout and intention-to-remain. The incentive increased response rates over time. The effect of the incentive did not differ between mediators and social workers. The $2 incentive was not cost effective for increasing response count. Implications are discussed for reducing nonresponse bias, decreasing time-to-response, and considering response rate versus response count. PMID- 29572702 TI - Depleted polymorphonuclear leukocytes in human metastatic liver reflect an altered immune microenvironment associated with recurrent metastasis. AB - BACKGROUND: Hepatic immunity, normally protective against neoplasia, is subverted in colorectal liver metastasis (CRLM). Here, we compare the inflammatory microenvironment of CRLM-bearing liver tissue to donor liver. METHODS: Twenty five patients undergoing resection for CRLM were recruited, 13 of whom developed intrahepatic recurrence within 18 months. Biopsies were obtained from tumour and normal liver tissue adjacent to and distal from, the tumour. Donor liver biopsies were obtained during transplantation. Biopsies were cultured and conditioned media (CM) screened for 102 inflammatory mediators. Twelve of these were validated by Luminex assay. Transwell assays measured cancer cell chemotaxis. Polymorphonuclear leukocytes (PMN) and lymphocytes were quantified in H&E sections. RESULTS: Fewer periportal tissue-resident PMN were present in metastatic liver compared to donor liver. Patients with the fewest PMN in liver tissue distal to their tumour had a shorter time to intrahepatic recurrence (P < 0.001). IL-6, CXCL1, CXCL5, G-CSF, GM-CSF, VEGF, LIF, and CCL3 were higher in liver-bearing CRLM compared to donor tissue. Consequently, cancer cells migrated equally towards CM of all regions of metastatic liver but not towards donor liver CM. CONCLUSIONS: The local inflammatory environment may affect both immune cell infiltration and cancer cell migration contributing to recurrence following resection for CRLM. PMID- 29572704 TI - Prognostic Impact of R0 Resection and Targeted Therapy for Colorectal Cancer with Synchronous Peritoneal Metastasis. AB - BACKGROUND: The National Comprehensive Cancer Network guidelines recommend R0 resection and targeted therapy, a combination of cytotoxic and molecular targeted agents, such as bevacizumab, cetuximab, and panitumumab, for colorectal cancer with synchronous peritoneal metastasis (M1c). While these therapeutic strategies are drawing attention, their efficacy has not been fully examined. METHODS: The study population comprised 248 consecutive M1c patients who were treated at the National Cancer Center Hospital from 1997 to 2013. Multivariate analyses were performed to evaluate relationships between overall survival and R0 resection and targeted therapy using Cox proportional hazards regression models. RESULTS: The 3 year overall survival (3 yOS) was 19.5%, and median survival time (MST) was 16.2 months in 248 M1c patients. R0 resection was performed in 34 patients (14%), yielding a 3-year overall survival (OS) of 48.3% and median survival time (MST) of 29.9 months. Targeted therapy was performed in 54 patients (22%) at least once during the course of treatment, yielding a 3-yr OS of 38.2% and MST of 23.9 months. After adjusting for other key clinical factors, such as the number of organs involved with metastases, performance status, primary tumor site, and extent of peritoneal metastasis, both R0 resection and targeted therapy were independent factors associated with longer OS. Targeted therapy was associated with a significantly longer OS compared with multiple cytotoxic agent therapy [hazard ratio 0.65; 95% confidence interval (0.44-0.94); p = 0.02]. CONCLUSIONS: If achievable, R0 resection is a desirable therapeutic strategy for patients with M1c colorectal cancer. Moreover, targeted therapy might be the optimal chemotherapy in this patient population. PMID- 29572705 TI - Is Low-Volume Disease in the Sentinel Node After Neoadjuvant Chemotherapy an Indication for Axillary Dissection? AB - BACKGROUND/OBJECTIVE: Intraoperative evaluation of sentinel lymph nodes (SLNs) after neoadjuvant chemotherapy (NAC) has a higher false-negative rate than in the primary surgical setting, particularly for small tumor deposits. Additional tumor burden seen with isolated tumor cells (ITCs) and micrometastases following primary surgery is low; however, it is unknown whether the same is true after NAC. We examined the false-negative rate of intraoperative frozen section (FS) after NAC, and the association between SLN metastasis size and residual disease at axillary lymph node dissection (ALND). METHODS: Patients undergoing SLN biopsy after NAC were identified. The association between SLN metastasis size and residual axillary disease was examined. RESULTS: From July 2008 to July 2017, 702 patients (711 cancers) had SLN biopsy after NAC. On FS, 181 had metastases, 530 were negative; 33 negative cases were positive on final pathology (false-negative rate 6.2%). Among patients with a positive FS, 3 (2%) had ITCs and no further disease on ALND; 41 (23%) had micrometastases and 125 (69%) had macrometastases. Fifty-nine percent of patients with micrometastases and 63% with macrometastases had one or more additional positive nodes at ALND. Among those with a false negative result, 10 (30%) had ITCs, 15 (46%) had micrometastases, and 8 (24%) had macrometastases; 17 had ALND and 59% had one or more additional positive lymph nodes. Overall, 1/6 (17%) patients with ITCs and 28/44 (64%) patients with micrometastases had additional nodal metastases at ALND. CONCLUSION: Low-volume SLN disease after NAC is not an indicator of a low risk of additional positive axillary nodes and remains an indication for ALND, even when not detected on intraoperative FS. PMID- 29572706 TI - A National-Level Validation of the New American Joint Committee on Cancer 8th Edition Subclassification of Stage IIA and B Anal Squamous Cell Cancer. AB - INTRODUCTION: The 8th edition of the American Joint Committee on Cancer (AJCC) updated the staging system of anal squamous cell cancer (ASCC) by subdividing stage II into A (T2N0M0) and B (T3N0M0) based on a secondary analysis of the RTOG 98-11 trial. We aimed to validate this new subclassification utilizing two nationally representative databases. MATERIALS: The National Cancer Database (NCDB) [2004-2014] and the Surveillance, Epidemiology, and End Results (SEER) database [1988-2013] were queried to identify patients with stage II ASCC. RESULTS: A total of 6651 and 2579 stage IIA (2-5 cm) and 1777 and 641 stage IIB (> 5 cm) patients were identified in the NCDB and SEER databases, respectively. Compared with stage IIB patients, stage IIA patients within the NCDB were more often females with fewer comorbidities. No significant differences were observed between age, race, receipt of chemotherapy and radiation, and mean radiation dose. Demographic, clinical, and pathologic characteristics were comparable between patients in both datasets. The 5-year OS was 72% and 69% for stage IIA versus 57% and 50% for stage IIB in the NCDB and SEER databases, respectively (p < 0.001). After adjustment for available demographic and clinical confounders, stage IIB was significantly associated with worse survival in both cohorts (hazard ratio 1.58 and 2.01, both p < 0.001). CONCLUSION: This study validates the new AJCC subclassification of stage II anal cancer into A and B based on size (2-5 cm vs. > 5 cm) in the general ASCC population. AJCC stage IIB patients represent a higher risk category that should be targeted with more aggressive/novel therapies. PMID- 29572707 TI - Prescription Drug Use and Cost Trends Among Medicaid-Enrolled Children with Disruptive Behavioral Disorders. AB - Disruptive behavior disorders (DBDs) are the most common mental health conditions in children. These conditions profoundly affect healthcare utilization and costs. Service use, costs, and diagnostic trends among pediatric Medicaid beneficiaries provide information regarding healthcare quality and potential for smarter spending. Using nationwide Medicaid administrative data, this study investigates diagnoses, prescription drug fills, and payments in 49 states and D.C. from 2006 to 2009 in Medicaid beneficiaries age 20 and under. Psychotherapeutic drug prescriptions and payments were calculated as a proportion of prescription totals. Results were considered by age, gender, race, and state. The results show a trend of increasing DBD diagnosis. Among prescription claims for children with diagnosed DBD, psychotherapeutic drug claims represented 30-40% of prescription claims but over half of prescription costs. This study indicates increasing clinical and financial needs for Medicaid-enrolled children with DBDs. Medicaid could potentially foster reforms in pediatric DBD treatments, particularly regarding medication use. PMID- 29572709 TI - The antiproliferative effect of pasireotide LAR alone and in combination with everolimus in patients with medullary thyroid cancer: a single-center, open label, phase II, proof-of-concept study. AB - PURPOSE: Medullary thyroid cancer (MTC) is a neuroendocrine tumour of the thyroid C cells. Pasireotide, a multi-receptor targeted somatostatin analogue, and everolimus, an inhibitor of mTOR, showed antitumour properties in neuroendocrine tumours. Aim of this study was to evaluate pasireotide alone and in combination with everolimus in patients with MTC. METHODS: Patients with progressive metastatic or persistent postoperative MTC received pasireotide LAR 60 mg/m for at least 6 months. Patients exhibiting progressive disease received everolimus 10 mg/d as combination therapy. Primary endpoint was progression free survival (PFS). Secondary endpoints included, overall survival, objective response rates, change in circulating markers, safety. Study registration no. NCT01625520. RESULTS: Nineteen consecutive patients were enrolled. Median follow-up was 31 months. Median PFS with pasireotide was 36 months (95% CI: 19.5-52.5). Nine patients (47%) had tumour progression: seven of them started everolimus in combination with pasireotide, achieving a median PFS of 9.0 months (95% CI: 0 21.83). Five of them (71%) had further tumour progression, one objective response (14.3%), one stopped treatment because of pulmonary embolism. Pasireotide alone and with everolimus was safe and required withdrawal only in one case. Diarrhoea and hyperglycaemia were the most frequent adverse events with pasireotide (grade 3 in 5.3% each). Hyperglycaemia was the most frequent grade 3 toxicity with the combination therapy (28.6%). CONCLUSIONS: Pasireotide therapy shows antiproliferative effects in persistent postoperative MTC suggesting further investigation on larger series of patients. In progressive MTC lesions, the combination pasireotide plus everolimus may be of benefit. Both schemes were safe and well tolerated. PMID- 29572708 TI - Klinefelter syndrome, insulin resistance, metabolic syndrome, and diabetes: review of literature and clinical perspectives. AB - PURPOSE: Klinefelter syndrome (KS), the most frequent chromosomic abnormality in males, is associated with hypergonadotropic hypogonadism and an increased risk of cardiovascular diseases (CVD). The mechanisms involved in increasing risk of cardiovascular morbidity and mortality are not completely understood. This review summarises the current understandings of the complex relationship between KS, metabolic syndrome and cardiovascular risk in order to plan future studies and improve current strategies to reduce mortality in this high-risk population. METHODS: We searched PubMed, Web of Science, and Scopus for manuscripts published prior to November 2017 using key words "Klinefelter syndrome" AND "insulin resistance" OR "metabolic syndrome" OR "diabetes mellitus" OR "cardiovascular disease" OR "testosterone". Manuscripts were collated, studied and carried forward for discussion where appropriate. RESULTS: Insulin resistance, metabolic syndrome, and type 2 diabetes are more frequently diagnosed in KS than in the general population; however, the contribution of hypogonadism to metabolic derangement is highly controversial. Whether this dangerous combination of risk factors fully explains the CVD burden of KS patients remains unclear. In addition, testosterone replacement therapy only exerts a marginal action on the CVD system. CONCLUSION: Since fat accumulation and distribution seem to play a relevant role in triggering metabolic abnormalities, an early diagnosis and a tailored intervention strategy with drugs aimed at targeting excessive visceral fat deposition appear necessary in patients with KS. PMID- 29572710 TI - Liquid L-thyroxine versus tablet L-thyroxine in patients on L- thyroxine replacement or suppressive therapy: a meta-analysis. AB - PURPOSE: To compare the effectiveness of liquid L-T4 (L-thyroxine) and tablet L T4 in patients on L-T4 replacement or suppressive therapy. METHODS: The Cochrane Library, PubMed, Embase, and Web of Science databases were searched to identify relevant articles. All prospective or randomized controlled studies (RCTs) comparing liquid L-T4 and tablet L-T4 in patients on L-T4 replacement or suppressive therapy were included in the analysis. RESULTS: Overall, the initial search of the four databases identified 1278 published studies; of these, eight studies were ultimately included in the meta-analysis. TSH (thyroid stimulating hormone) levels were significantly suppressed in patients on liquid L-T4 compared with those on tablet L-T4, in patients on L-T4 suppressive therapy with L-T4 malabsorption (Mean Difference (MD) = -2.26, 95% Confidence Interval (CI): -3.59, -0.93; P = 0.0009)). However, liquid L-T4 and tablet L-T4 did not show a statistically significant difference in patients on L-T4 suppressive therapy without malabsorption (MD = 0.08, 95% CI: -0.31, 0.47; P = 0.69). TSH levels were significantly normalized in patients on liquid L-T4 compared with those on tablet L-T4, in Patients on L-T4 replacement therapy with L-T4 malabsorption (MD = 3.20, 95% CI: -5.08, -1.32; P = 0.0009). However, liquid L-T4 and tablet L-T4 did not show a statistically significant difference in patients on L-T4 replacement therapy without malabsorption (MD = 0.91, 95% CI: -0.03, 1.86; P = 0.06). CONCLUSION: Liquid L-T4 is more efficient than tablet L-T4 in patients on L-T4 replacement or suppressive therapy with malabsorption. No significant differences were observed in patients without malabsorption. Further studies should be conducted to verify these findings. PMID- 29572713 TI - Tree-in-bud sign. PMID- 29572711 TI - Low-dose Synachten test with measurement of salivary cortisol in adult patients with beta-thalassemia major. AB - PURPOSE: Beta-thalassemia major is a severe, congenital hematological disorder and, if untreated, leads to early mortality. Progress in therapeutical strategies improved clinical outcomes and life expectancy; however, increased survival led to the development of new disorders, including endocrinopathies. Little is known on the possible impairment of adrenocortical function, a potentially life threatening condition, in long-term thalassaemic survivors. We therefore decided to assess adrenal reserve and the value of salivary cortisol during ACTH stimulation in the diagnosis of adrenocortical insufficiency in adult patients with beta-thalassemia major. METHODS: Cross-sectional study including 72 adults with beta-thalassemia major. Patients were tested with 1 ug ACTH for serum and salivary cortisol. RESULTS: Subnormal serum cortisol responses to ACTH stimulation (i.e., <500 nmol/l) were registered in 15 out of 72 patients. Salivary cortisol increased in parallel with serum cortisol and a clear-cut positive correlation was detected at each timepoint. Moreover, peak salivary cortisol values after ACTH stimulation were significantly lower in patients with impaired adrenal reserve (513.6 +/- 52.33 vs. 914.1 +/- 44.04 nmol/l p < 0.0001). CONCLUSIONS: Our results attest to the need for testing for adrenal insufficiency among adult thalassaemic patients, as up to 20% presented impaired adrenal reserve. Salivary and serum cortisol levels during stimulation with ACTH were closely correlated and the use of salivary cortisol sampling during ACTH testing may represent a surrogate to serum cortisol in these patients. PMID- 29572712 TI - [Imaging of gastrointestinal inflammation : Characteristic patterns and signs]. AB - CLINICAL PROBLEM: Pathological conditions of the gastrointestinal tract can result from various disorders, including inflammatory, infectious, neoplastic, and ischemic diseases. RADIOLOGICAL STANDARD PROCEDURES: Cross-sectional imaging techniques have largely replaced many of the conventional fluoroscopic examinations, such as small bowel follow-through and double-contrast barium enema. The former allow for time-efficient, accurate, and minimally invasive diagnostics. Therefore, they have become important diagnostic tools for the evaluation of inflammatory diseases of the gastrointestinal tract. The distension of the intestinal lumen with orally administered neutral contrast media improves not only the evaluation of the intraluminal aspect, but also of the cross sectional appearance. Furthermore, with cross-sectional imaging techniques, the additional assessment of the extraintestinal structures and organs is also possible. METHODICAL INNOVATIONS AND ASSESSMENT: With the ongoing development of scanner and software technology, pathologic conditions of the gastrointestinal wall can be characterized in more detail by both computed tomography and magnetic resonance imaging. A structured approach, based on the analysis of typical radiological signs and patterns, combined with the evaluation of extraintestinal findings may help to assign the observed imaging findings to specific disease groups. RECOMMENDATIONS: This article summarizes common signs and typical patterns frequently seen in inflammatory conditions of the gastrointestinal tract. A systematic approach for structured analysis of specific and nonspecific imaging features and common pitfalls may aid in the interpretation and help to narrow the spectrum of potential differential diagnoses. PMID- 29572714 TI - Accuracy of liver surface nodularity quantification on MDCT for staging hepatic fibrosis in patients with hepatitis C virus. AB - PURPOSE: To evaluate semi-automated measurement of liver surface nodularity (LSN) on MDCT in a cause-specific cohort of patients with chronic hepatitis C virus infection (HCV) for identification of hepatic fibrosis (stages F0-4). METHODS: MDCT scans in patients with known HCV were evaluated with an independently validated, semi-automated LSN measurement tool. Consecutive LSN measurements along the anterior liver surface were performed to derive mean LSN scores. Scores were compared with METAVIR fibrosis stage (F0-4). Fibrosis stages F0-3 were based on biopsy results within 1 year of CT. Most patients with cirrhosis (F4) also had biopsy within 1 year; the remaining cases had unequivocal clinical/imaging evidence of cirrhosis and biopsy was not indicated. RESULTS: 288 patients (79F/209M; mean age, 49.7 years) with known HCV were stratified based on METAVIR fibrosis stage: F0 (n = 43), F1 (n = 29), F2 (n = 53), F3 (n = 37), and F4 (n = 126). LSN scores increased with increasing fibrosis (mean: F0 = 2.3 +/- 0.2, F1 = 2.4 +/- 0.3, F2 = 2.6 +/- 0.5, F3 = 2.9 +/- 0.6, F4 = 3.8 +/- 1.0; p < 0.001). For identification of significant fibrosis (>= F2), advanced fibrosis (>= F3), and cirrhosis (>= F4), the ROC AUCs were 0.88, 0.89, and 0.90, respectively. The sensitivity and specificity for significant fibrosis (>= F2) using LSN threshold of 2.80 were 0.68 and 0.97; for advanced fibrosis (>= F3; threshold = 2.77) were 0.83 and 0.85; and for cirrhosis (>= F4, LSN threshold = 2.9) were 0.90 and 0.80. CONCLUSION: Liver surface nodularity assessment at MDCT allows for accurate discrimination of intermediate stages of hepatic fibrosis in a cause-specific cohort of patients with HCV, particularly at more advanced levels. PMID- 29572715 TI - Right ventricular lead location, right-left ventricular lead interaction, and long-term outcomes in cardiac resynchronization therapy patients. AB - BACKGROUND: The effects of right ventricular (RV) lead location and the combination of RV and left ventricular (LV) lead locations on long-term outcomes in patients receiving cardiac resynchronization therapy with defibrillator (CRT D) are not well understood. METHODS: Our cohort consisted of 743 CRT-D patients from MADIT-CRT. We evaluated long-term death and combined heart failure or death (HF/death) in patients with non-apical RV vs. apical RV leads. We further assessed these long-term outcomes based on the combination of RV and LV leads, termed "RV-LV lead interaction." Patients with non-apical RV and apical LV leads and those with apical RV and non-apical LV leads were described to have "discordant RV and LV leads." Patients with RV and LV leads that were both non apical or both apical were defined to have "concordant RV and LV leads." RESULTS: There were no differences in death and HF/death between patients with non-apical RV vs. apical RV leads. However, patients with non-apical RV and apical LV leads had higher mortality risk, relative to those with apical RV and non-apical LV leads (HR = 4.06, 95% CI 1.73-9.53, p = 0.001) as well as those with both leads in the non-apical (HR = 3.82, 95% CI 1.33-10.98, p = 0.013) or apical (HR = 3.40, 95% CI 1.24-9.37, p = 0.018) positions. There was no difference in HF/death by RV LV lead sub-groups. CONCLUSION: Among CRT-D patients, long-term outcomes were similar for non-apical RV and apical RV leads. However, mortality risk was increased with discordant RV and LV leads, when a non-apical RV lead was combined with an apical LV lead. PMID- 29572716 TI - Comparison of single-coil lead versus dual-coil lead of implantable cardioverter defibrillator on lead-related venous complications in a canine model. AB - PURPOSE: Dual- coil lead (DCL) of implantable cardioverter defibrillator (ICD) is preferred clinically in patients. However, it is related to higher risk of venous stenosis and thrombosis. The present study was done to compare the fibrosis and extraction of the leads between the single-coil lead (SCL) and DCL in animal models. METHODS: This was a chronic animal study with a follow-up duration of 6 months. Twenty mongrel dogs were randomly divided into DCL group or SCL group. Venography was performed before the sacrifice to evaluate the venous stenosis in vivo. The maximum pulling-out tension of the ICD lead was measured by a tensometer. Hematoxylin-eosin stain and toluidine blue O stain were applied to show the pathological changes of the superior vena cava (SVC) to evaluate the fibrosis and the thickness of the SVC adjacent to the leads. RESULTS: The DCL group showed higher incidence of venous stenosis (OR = 31.5; 95% CI, 2.35-422.3; p = 0.005). It revealed increased tension to extract the leads in the DCL group (5.96 +/- 1.86 vs. 3.68 +/- 1.46 N, p = 0.027). The difference of venous wall thickness of SVC was 4.3 +/- 0.3 fold-changes between two groups (p = 0.007). Moreover, the degree of venous wall fibrosis in DCL group was more serious than that it in SCL group (3.61 +/- 1.26 vs. 1.08 +/- 1.35 mm2, p = 0.015). CONCLUSION: The DCL was proved to increase thrombosis, fibrosis, and stenosis in the SVC. Likewise, the DCL was mechanically harder to be extracted than the SCL. Our study showed that lead-related complications of the DCLs were higher than those of the SCLs regardless of the equal defibrillation thresholds between them. Results of the present study would help to choose the proper lead which could be removed. PMID- 29572717 TI - Ventricular arrhythmias originating from the cardiac crux and the basal inferior segment of the interventricular septum in the patients with structural heart diseases: characteristics, mapping, and electrophysiological properties. AB - PURPOSE: There are few reports describing ventricular arrhythmias (VAs) from the crux and the corresponding endocardial site, i.e., the basal inferior segment of the interventricular septum (IVS). We aimed to investigate a distinct clinical group of VAs arising from the endocardium at this area in patients with structural heart diseases (SHD). METHODS: We included 17 patients with SHD and clinically documented VAs. Thirteen patients underwent endocardial mapping only. Three patients underwent both epicardial and endocardial approaches and one had only epicardial mapping. Eighteen VAs were identified, 14 focal and 4 reentrant VAs, confirmed by entrainment. RESULTS: There were 2 VAs from the crux, 5 VAs from the corresponding endocardial site in the right ventricle (RV), and 11 from the site in the left ventricle (LV). Compared with the VAs from RV endocardium, VAs from LV endocardium had a higher R wave in V3 than V2 (V2R/V3R ratio, 1.83 +/ 0.84 vs. 0.86 +/- 0.38, P = 0.008) and a higher V3 transition ratio percentage (2.16 +/- 2.07 vs. 0.58 +/- 0.62, P = 0.008). Combining all 16 patients with endocardial mapping, there were also lower bipolar voltages (1.21 +/- 1.05 vs. 3.10 +/- 2.65 mv, P < 0.0001), lower unipolar voltages (4.05 +/- 1.92 vs. 5.75 +/ 2.90 mv, P < 0.0001), and longer local electrocardiogram (EGM) lateness (157.6 +/- 47.9 vs.140.3 +/- 52.5 ms, P = 0.0001) in the dominant chambers. CONCLUSIONS: In VAs from the crux and the corresponding endocardial site, the complete ECG V2R/V3R ratio and V3 transition ratio percentage could differentiate the VAs from the RV or LV endocardium. The lower unipolar, bipolar voltage mapping, and longer EGM lateness are helpful to identify the abnormal substrate in the endocardium in these patients. PMID- 29572718 TI - Disparities in maternal health services in sub-Saharan Africa. AB - OBJECTIVES: To examine the progress of and disparities in the provision of key maternal health services in the sub-Saharan Africa (SSA) region. METHODS: A time trend analysis of disparities in antenatal care (ANC) and skilled birth attendance (SBA) coverage in SSA over the last 25 years was conducted. The average values of each country's 5-year period data were used for analysis. Absolute and relative disparities were examined by time period, economic class, geographic group and clusters. Analysis of variance was used to compare progresses in coverage across time. RESULTS: Regional median ANC coverage and SBA increased by 8% points and 15% points, respectively, during the 25-year period. The rank score of SBA has shown significant improvement only in the recent period. A 33.3% disparity between ANC and SBA was observed in the most recent period. The relative disparity by economic class and cluster was higher for SBA than ANC coverage. CONCLUSIONS: The region showed improvement in both indicators across time. Regional disparity in ANC narrowed down while that of SBA remained high. These were mainly associated with economic class and cluster of countries. PMID- 29572719 TI - A Systematic Review of Studies Comparing the Measurement Properties of the Three Level and Five-Level Versions of the EQ-5D. AB - BACKGROUND: Since the introduction of the five-level version of the EQ-5D (5L), many studies have comparatively investigated the measurement properties of the original three-level version (3L) with the 5L version. OBJECTIVE: The aim of this study was to consolidate the available evidence on the performance of both instruments. METHODS: A systematic literature search of studies in the English and German languages was conducted (2007-January 2018) using the PubMed, EMBASE, and PsycINFO (EBSCO) databases, as well as the EuroQol Research Foundation website. Data were extracted and assessed on missing values, distributional properties, informativity indices (Shannon's H' and J'), inconsistencies, responsiveness, and test-retest reliability. RESULTS: Twenty-four studies were included in the review. Missing values and floor effects (percentage reporting the worst health state) were found to be negligible for both 3L and 5L (< 5%). From 18 studies, inconsistencies ranged from 0 to 10.6%, although they were generally well below 5%, with 9 studies reporting the most inconsistencies for Usual Activities (mean percentage 4.1%). Shannon's indices were always higher for 5L than for 3L, and all but three studies reported lower ceiling effects ('11111') for 5L than for 3L. There is mixed and insufficient evidence on responsiveness and test-retest reliability, although results on index values showed better performance for 5L on test-retest reliability. CONCLUSION: Overall, studies showed similar or better measurement properties of the 5L compared with the 3L, and evidence indicated moderately better distributional parameters and substantial improvement in informativity for the 5L compared with the 3L. Insufficient evidence on responsiveness and test-retest reliability implies further research is needed. PMID- 29572720 TI - A 25-year retrospective analysis of the American Society of Anesthesiologists physical status classification: did we "up-code" young obese patients when obesity was not yet considered a disease? AB - PURPOSE: The influence of obesity on anesthetic risk remains controversial, and obesity has only recently been specifically identified as a criterion by which a patient can be given a higher American Society of Anesthesiologists-physical status (ASA-PS) score. Nevertheless, we hypothesized that clinicians had assigned obese patients a greater ASA-PS score before obesity became an "official" criterion in 2015. METHODS: Basic demographic and physical details were collected on patients receiving anesthetics in the Virginia Commonwealth University Health System between 1986 and 2010. The risk ratio (RR) of "up-coding" ASA-PS classification assignments was calculated for patients of varying body mass index (BMI). We specifically focused on the subset of patients aged 20-29 yr in whom the medical sequelae of obesity would not yet likely be manifest. RESULTS: Among a total of 194,698 patients, the percentage who were obese increased from 20% to 39% between 1986 and 2010. Obese patients of all ages were more likely than non obese patients to be classified as ASA-PS II-IV rather than ASA-PS I. The RR and ratio of RR analyses indicated a consistent pattern of up-coding patients with greater BMI (contingency table Chi-square: P < 0.001). Most notably, relative to patients with a normal BMI, young obese patients aged 20-29 yr had an increased likelihood of up-coding in ASA-PS compared with obese patients in the older cohorts. CONCLUSIONS: These findings suggest a consistent and temporally stable practice of up-coding obese patients despite this lack of explicit guidance. The ASA House of Delegates' recent decision to specifically mention obesity reinforces long-existing practices regarding ASA-PS coding and will likely not degrade the validity of data sets collected before the change. PMID- 29572721 TI - Planning and navigation as active inference. AB - This paper introduces an active inference formulation of planning and navigation. It illustrates how the exploitation-exploration dilemma is dissolved by acting to minimise uncertainty (i.e. expected surprise or free energy). We use simulations of a maze problem to illustrate how agents can solve quite complicated problems using context sensitive prior preferences to form subgoals. Our focus is on how epistemic behaviour-driven by novelty and the imperative to reduce uncertainty about the world-contextualises pragmatic or goal-directed behaviour. Using simulations, we illustrate the underlying process theory with synthetic behavioural and electrophysiological responses during exploration of a maze and subsequent navigation to a target location. An interesting phenomenon that emerged from the simulations was a putative distinction between 'place cells' that fire when a subgoal is reached-and 'path cells'-that fire until a subgoal is reached. PMID- 29572722 TI - Fruit and Vegetable Intake: the Interplay of Planning, Social Support, and Sex. AB - PURPOSE: Intention and planning are important predictors of dietary change. However, little attention has been given yet to the relationship between them as a function of other social-cognitive factors and their interplay with socio demographics such as sex. METHODS: In an observational study (1520 women, 430 men) with two measurement points in time, intention (predictor), planning (mediator), social support (first moderator), and sex (second moderator) were assessed to predict changes in diet separately for fruit and vegetable intake. RESULTS: All predictors had a main effect on fruit intake but no interactions emerged. For vegetable intake, the mediation-chain was qualified by a three-way interaction: for women, the lower the perceived social support, the more the translation of planning into behavior; for men, the higher the perceived social support, the more the translation of planning into behavior. CONCLUSIONS: Even though intention and planning are predictors of dietary change, they operate differently under specific conditions (level of social support), for specific subgroups (men vs. women), and for different target behaviors (fruit vs. vegetable intake). These results suggest to further examine the mechanisms by which intentions are translated into behavior via planning. PMID- 29572724 TI - Is BRCA Mutation Testing Cost Effective for Early Stage Breast Cancer Patients Compared to Routine Clinical Surveillance? The Case of an Upper Middle-Income Country in Asia. AB - OBJECTIVE: Previous studies showed that offering BRCA mutation testing to population subgroups at high risk of harbouring the mutation may be cost effective, yet no evidence is available for low- or middle-income countries (LMIC) and in Asia. We estimated the cost effectiveness of BRCA mutation testing in early-stage breast cancer patients with high pre-test probability of harbouring the mutation in Malaysia, an LMIC in Asia. METHODS: We developed a decision analytic model to estimate the lifetime costs and quality-adjusted life years (QALYs) accrued through BRCA mutation testing or routine clinical surveillance (RCS) for a hypothetical cohort of 1000 early-stage breast cancer patients aged 40 years. In the model, patients would decide whether to accept testing and to undertake risk-reducing mastectomy, oophorectomy, tamoxifen, combinations or neither. We calculated the incremental cost-effectiveness ratio (ICER) from the health system perspective. A series of sensitivity analyses were performed. RESULTS: In the base case, testing generated 11.2 QALYs over the lifetime and cost US$4815 per patient whereas RCS generated 11.1 QALYs and cost US$4574 per patient. The ICER of US$2725/QALY was below the cost-effective thresholds. The ICER was sensitive to the discounting of cost, cost of BRCA mutation testing and utility of being risk-free, but the ICERs remained below the thresholds. Probabilistic sensitivity analysis showed that at a threshold of US$9500/QALY, 99.9% of simulations favoured BRCA mutation testing over RCS. CONCLUSIONS: Offering BRCA mutation testing to early-stage breast cancer patients identified using a locally-validated risk-assessment tool may be cost effective compared to RCS in Malaysia. PMID- 29572725 TI - Individual and Institutional Corruption in European and US Healthcare: Overview and Link of Various Corruption Typologies. AB - In recent years, the fight against healthcare corruption has intensified. Estimates from the European Healthcare Fraud and Corruption Network calculate an approximate ?56 billion annual loss to Europe as a result of corruption. To promote understanding of the complexity and interconnection of corrupt activities, we aim to present healthcare-related corruption typologies of the European Union and European Healthcare Fraud and Corruption Network. We subsequently link them to the typology of individual and institutional corruption introduced by Dennis Thompson in the context of investigating misconduct of US Congressional members. According to Thompson, individual corruption is the personal gain of individuals performing duties within an institution in exchange for nurturing private interests, while institutional corruption pertains to the failure of the institution in directing the individual's behaviour towards the achievement of the institution's primary purpose because the institutional design promotes the pursuit of individual goals. Effective anti-corruption activities not only require the enactment of anti-corruption laws but also the monitoring and, where appropriate, revision of institutional frameworks to prevent the undermining of the primary purposes of health systems or institutions. To gain further understanding of the similarities and differences of the three typologies, prime examples of corrupt activities in the health sector in the European Union and USA (along with their potential remedies) are provided. Linking corruption cases to Thompson's typology revealed that many corrupt activities may show elements of both individual and institutional corruption because they are intertwined, partly overlap and may occur jointly. Hence, sanctioning individual actors only does not target the problem. PMID- 29572726 TI - The evaluation of the effect of venous diameter measurement by ultrasonography on pain and withdrawal response. AB - PURPOSE: Rocuronium and propofol are used in the induction of anesthesia give discomfort to the patients. We aimed to investigate the relationship between venous diameter measured using ultrasonography, and pain and withdrawal movements after propofol and rocuronium applied with intravenous (IV). METHODS: This prospective-observational study was performed on 142 voluntary patients undergoing surgical operation under general anesthesia. An ultrasonography was used to measure the vein transverse diameter. Patients with a venous transverse diameter of <=2 mm were classified as group 1 (n = 50), while patients with a diameter of > 2 mm were classified as group 2 (n = 92). The propofol pain was assessed according to the verbal rating scale (VRS). In addition, the withdrawal movements of the rocuronium injection were evaluated using the four-point scale. RESULTS: There was no difference between the two groups in terms of the demographic data. The patients have pain after propofol 38.2% and withdrawal movements after rocuronium 42.4% were detected. The maximum number of patients without pain after propofol injection (78.2%) and without withdrawal movements after rocuronium (76%) was found to be higher in group 2 (p = 0.001). CONCLUSION: In this study, we found a reduction in the incidence and severity of pain and withdrawal movements in intravenous propofol and rocuronium administration through peripheral venous vessels of large diameter. We believe that the clinical drug injection through vessels with large venous diameter with the help of USG may be a non-invasive, simple, and reliable method to reduce pain and withdrawal movements in propofol and rocuronium injections. PMID- 29572727 TI - Should we rely on Doppler ultrasound for evaluation of testicular solid lesions? AB - PURPOSE: Colour Doppler ultrasound (CDUS) is the main radiologic tool to evaluate scrotal masses and intratesticular-vascularised solid lesions are mostly considered malign lesions. Objective of this trial is determine ratio of benign lesions in patients with hypervascularised solid intratesticular lesions. MATERIAL AND METHOD: Patients who underwent radical orchiectomy due to hypervascularised intratesticular solid lesions detected in CDUS are evaluated retrospectively. Those with previous testicular cancer history and inguinal/scrotal surgeries were excluded from the study. All patients are evaluated for age, preoperative testicular atrophy, multicentricity, echotexture and size of solid lesions, preoperative tumor markers (AFP, bHCG and LDH), and postoperative pathology results. Two tailed p value test was used to evaluate numeric parameters and Fisher's exact test was used to evaluate non-numeric parameters. RESULTS: A total of 117 patients with a mean age of 35.9 (5-86) were included to the study. Mean size of solid lesions was 4.39 cm. Seven patients had subcentimeter (subcm) lesions. 101 patients had hypoechoic, ten patients had isoechoic and six patients hyperechoic solid lesions. Preoperatively 60 patients (51.2%) had at least one tumor marker elevated. Postoperative pathology examination resulted to; 21 patients (17.9%) had benign lesions. Elevation of tumor markers, palpability, hypoechoic texture and larger size of the solid lesion were found to be parameters that predict malignancy. CONCLUSION: Benign incidence of vascular testicular solid lesions detected with scrotal ultrasound with colour Doppler is greater than expected. In patients with smaller, non palpable lesions without elevated tumor markers, treatment options other than radical orchiectomy such as testicular sparing surgery should be considered.

PMID- 29572729 TI - Decision-making for complex scapula and ipsilateral clavicle fractures: a review. AB - INTRODUCTION: Complex scapula with ipsilateral clavicle fracures remains a challange and treatment recommendations are still missing. This review provides an overview of the evolution of the definition, classification and treatment strategies for complex scapula and ipsilateral clavicle fractures. As with other rare conditions, consensus has not been reached on the most suitable management strategies to treat these patients. The aim of this review is twofold: to compile and summarize the currently available literature on this topic, and to recommend treatment approaches. MATERIALS AND METHODS: Included in the review are the following topics: biomechanics of scapula and ipsilateral clavicle fractures, preoperative radiological evaluation, surgical treatment of the clavicle only, surgical treatment of both the clavicle and scapula, and nonsurgical treatment options. RESULTS: A decision-making algorithm is proposed for different treatment strategies based on pre-operative parameters, and an example of a case treated our institution is presented to illustrate use of the algorithm. DISCUSSION: The role of instability in complex scapula with ipsilateral clavicle fractures remains unclear. The question of stability is preoperatively less relevant than the question of whether the dislocated fragments lead to compromised shoulder function. PMID- 29572730 TI - Could resuscitative endovascular balloon occlusion of the aorta improve survival among severely injured patients with post-intubation hypotension? AB - Current literature shows the association of post-intubation hypotension and increased odds of mortality in critically ill non-trauma and trauma populations. However, there is a lack of research on potential interventions that can prevent or ameliorate the consequences of endotracheal intubation and thus improve the prognosis of trauma patients with post-intubation hypotension. This review paper hypothesizes that the deployment of REBOA among trauma patients with PIH, by its physiologic effects, will reduce the odds of mortality in this population. The objective of this paper is to review the current literature on REBOA and post intubation hypotension, and, furthermore, to provide a rational hypothesis on the potential role of REBOA in severely injured patients with post-intubation hypotension. PMID- 29572731 TI - DFT study of nano zinc/copper voltaic cells. AB - To facilitate the development of new materials for use in batteries, it is necessary to develop ab initio full-electron computational techniques for modeling potential new battery materials. Here, we tested density functional theory procedures that are accurate enough to obtain the energetics of a zinc/copper voltaic cell. We found the magnitude of the zero-point energy correction to be 0.01-0.2 kcal/mol per atom or molecule and the magnitude of the dispersion correction to be 0.1-0.6 kcal/mol per atom or molecule for Zn n , (H2O) n , [Formula: see text], [Formula: see text], and Cu n . Counterpoise correction significantly affected the values of ?[Formula: see text], ?[Formula: see text], and ?Esolv by 1.0-3.1 kcal/mol per atom or molecule at the B3PW91/6 31G(d) level of theory, but by only 0.04-0.4 kcal/mol per atom or molecule at the B3PW91/cc-pVTZ level of theory. The application of B3PW91/6-31G(d) yielded results that differed from macroscopic experimental values by 0.1-7.1 kcal/mol per atom or molecule, whereas applying B3PW91/cc-pVTZ produced results that differed from macroscopic experimental values by 0.1-4.8 kcal/mol per atom or molecule, with the smallest differences occurring for reactions with a small macroscopic experimental ?E and the largest differences occurring for reactions with a large macroscopic experimental ?E, implying size consistency. PMID- 29572723 TI - Thermodynamics in Neurodegenerative Diseases: Interplay Between Canonical WNT/Beta-Catenin Pathway-PPAR Gamma, Energy Metabolism and Circadian Rhythms. AB - Entropy production rate is increased by several metabolic and thermodynamics abnormalities in neurodegenerative diseases (NDs). Irreversible processes are quantified by changes in the entropy production rate. This review is focused on the opposing interactions observed in NDs between the canonical WNT/beta-catenin pathway and PPAR gamma and their metabolic and thermodynamic implications. In amyotrophic lateral sclerosis and Huntington's disease, WNT/beta-catenin pathway is upregulated, whereas PPAR gamma is downregulated. In Alzheimer's disease and Parkinson's disease, WNT/beta-catenin pathway is downregulated while PPAR gamma is upregulated. The dysregulation of the canonical WNT/beta-catenin pathway is responsible for the modification of thermodynamics behaviors of metabolic enzymes. Upregulation of WNT/beta-catenin pathway leads to aerobic glycolysis, named Warburg effect, through activated enzymes, such as glucose transporter (Glut), pyruvate kinase M2 (PKM2), pyruvate dehydrogenase kinase 1(PDK1), monocarboxylate lactate transporter 1 (MCT-1), lactic dehydrogenase kinase-A (LDH A) and inactivation of pyruvate dehydrogenase complex (PDH). Downregulation of WNT/beta-catenin pathway leads to oxidative stress and cell death through inactivation of Glut, PKM2, PDK1, MCT-1, LDH-A but activation of PDH. In addition, in NDs, PPAR gamma is dysregulated, whereas it contributes to the regulation of several key circadian genes. NDs show many dysregulation in the mediation of circadian clock genes and so of circadian rhythms. Thermodynamics rhythms operate far-from-equilibrium and partly regulate interactions between WNT/beta-catenin pathway and PPAR gamma. In NDs, metabolism, thermodynamics and circadian rhythms are tightly interrelated. PMID- 29572732 TI - Efficacy and Safety of Sublingual Fentanyl Tablets in Breakthrough Cancer Pain Management According to Cancer Stage and Background Opioid Medication. AB - OBJECTIVE: Our objective was to assess the effect of sublingual fentanyl tablets (SFTs) on pain relief, quality of life, and adverse effects in patients with cancer pain, according to cancer stage and background opioid regimen. METHODS: Subgroup analyses from a recently completed study were performed according to cancer stage (locally advanced cancer [LAC] vs. metastatic cancer) and most frequent background opioid medication (fentanyl vs. oxycodone/naloxone). The efficacy and safety of SFTs were evaluated, recording pain intensity (PI), onset of pain relief, and adverse events (AEs). Health status was assessed with the Short Form 12, version 2 (SF-12v2) questionnaire and the Hospital Anxiety and Depression Scale (anxiety subscale [HADS-A] and depression subscale [HADS-D]). RESULTS: In total, 54 (67.5%) patients had LAC and 26 (32.5%) had metastatic cancer. The oxycodone/naloxone group included 39 patients (48.1%) and the fentanyl group 29 (35.8%). In all subgroups, pain relief was achieved within 5 min in an increasing number of individuals over time; at the end of the study, PI values decreased (PI-end: 44.4% for LAC vs. 57.9% for metastatic cancer; 44.4% for fentanyl vs. 38.6% for oxycodone/naloxone). HADS and mental component summary (MCS) SF-12v2 scores significantly improved in the LAC group (HADS-A 9.44-8.04; HADS-D 10.46-8.15; MCS 44.69-45.94) and in the fentanyl group (HADS-A 10.05-8.33; HADS-D 11.95-8.76; MCS 44.38-47.19). AEs were reported in few patients and were mostly mild. CONCLUSIONS: Exploratory subgroup analyses show the efficacy and safety of SFTs for the treatment of breakthrough pain in patients with cancer, regardless of their cancer stage and background opioid medication. PMID- 29572733 TI - Williams Syndrome and Anesthesia for Non-cardiac Surgery: High Risk Can Be Mitigated with Appropriate Planning. AB - Patients with Williams syndrome are considered at high risk for anesthesia related adverse events. At our institution, all William syndrome patients undergoing cardiac surgical, cardiac catheterization/interventional procedures, and cardiac imaging studies are cared for by cardiac anesthesiologists. All William syndrome patients undergoing non-cardiac surgical, interventional, or imaging studies are cared for by main operating room pediatric anesthesiologists with consultative input from a cardiac anesthesiologist. We reviewed our experience with 75 patients undergoing 202 separate anesthetics for 95 non cardiac procedures and 107 cardiac procedures from 2012 to 2016. The mean age was 7.5 +/- 7.0 years and the mean weight was 22.3 +/- 17.0 kg. One hundred and eighty-seven patients had a general anesthetic (92.6%). Medications used included etomidate in 26.2%, propofol in 37.6%, isoflurane in 47.5%, and sevoflurane in 68.3%. Vasopressors and inotropes were required including calcium (22.8%), dopamine (10.4%), norepinephrine (17.3%), phenylephrine (35.1%), vasopressin (0.5%), and ephedrine (5.4%). The median length of stay after anesthesia was 2.8 days (range 0-32). No adverse events occurred in 89.6% of anesthetics. There were two cases of cardiac arrest, one of which required extracorporeal life support for resuscitation. Of the non-cardiac surgical procedures, 95.7% did not have a cardiovascular adverse event. Patients with Williams syndrome are at high risk for anesthesia, especially when undergoing cardiac procedures. The risk can be mitigated with appropriate planning and adherence to the hemodynamic goals for non-cardiac surgical procedures. PMID- 29572734 TI - Health-related quality of life in adolescent and young adult cancer survivors. AB - PURPOSE: Today, survival rates for adolescent and young adult (AYA) cancer patients exceed 80%. However, cancer and treatment leave many patients suffering from chronic conditions. These late effects may impair their health-related quality of life (HRQoL). We aimed to (1) compare HRQoL of AYA cancer survivors with the Swiss general population and (2) investigate socio-demographic and cancer-related characteristics associated with poor HRQoL. METHODS: AYA cancer survivors (age 16-25 at diagnosis; >=5 years survival) who had been identified through the Cancer Registry Zurich and Zug, Switzerland, filled out a questionnaire. We assessed HRQoL using the Short-Form 12 (SF-12), producing two scores: Physical Component Summary score (PCS, physical health) and Mental Component Summary score (MCS, mental health). We used multivariable logistic regression analyses to investigate associated characteristics. RESULTS: We compared 155 survivors with 350 controls. Survivors had significantly lower physical health than controls (mean = 52.5 vs. mean = 54.7, p < 0.001). Male survivors reported better mental health than controls (55.2 vs.53.3, p = 0.078) and females slightly worse (49.8 vs. 51.8, p = 0.285). Poor physical health was strongly associated with having a migration background (OR = 4.63, p = 0.008) and unemployment (OR = 7.66, p = 0.005). Poor mental health was associated with female sex (OR = 2.69, p = 0.057), suffering from late effects (OR = 5.91, p < 0.001) and a migration background (OR = 5.82, p = 0.004). CONCLUSIONS: Results emphasize the need for individualized support services to improve survivors' HRQoL in vulnerable subgroups. We recommend adapted care for women and migrants, in addition to educational and employment support systems. PMID- 29572735 TI - Correlation and differences in cervical sagittal alignment parameters between cervical radiographs and magnetic resonance images. AB - PURPOSE: Although cervical alignment is better assessed using standing radiography than supine magnetic resonance imaging (MRI), few studies have investigated this. This study aimed to investigate the difference in alignment between standing radiographs and supine MRI images, and assess whether neck position affects the cervical parameters and neurological changes. METHODS: We analyzed 53 patients, measuring the O-C2 angle, C2-7 angle (the distinction between the lordotic and kyphotic groups), T1 slope, neck tilt, thoracic inlet angle, and the C2-7 sagittal vertical axis. Inter- and intra-group analyses were conducted to identify any difference between standing radiography and supine MRI. Statistical differences between the cervical parameters were compared. RESULTS: Strong correlations were noted between the equivalent parameters in the radiographs and MRI images, whereas no significant difference was observed in C2 7 angle in the kyphotic group between the radiographs and MRI images, or for neck tilt between the radiographs and MRI images. However, in the lordotic group, the C2-7 angle was significantly different between the two types of images and larger in the radiographs than in the MRI images (C2-7 angle in the radiographs: C2-7 angle in the MRI images: 4.49 degrees , p < 0.001). CONCLUSIONS: Neck tilt was a constant parameter. The C2-7 angle in the kyphotic group was similar between the standing radiographs and the supine MRI images; however, the C2-7 angle in the lordotic group was different. Therefore, we recommend that standing cervical radiographs should be preoperatively obtained for all surgical patients. The slides can be retrieved under Electronic Supplementary Material. PMID- 29572736 TI - Anterior management of C2 fractures using miniplate fixation: outcome, function and quality of life in a case series of 15 patients. AB - PURPOSE: The classification systems by Anderson and D'Alonzo, Effendi, Benzel and others have limitations when it comes to morphologically categorising fractures of the second cervical vertebral body (C2) that present with or without an additional fracture of the dens or with or without an extension of the fracture line into the vertebral arch and displacement. Currently, there are no definitive recommendations for the treatment of fractures at the junction of the dens with the vertebral body of C2 on the basis of outcome and stability data. Depending on patient anatomy, either anterior or posterior approaches can be used to fuse C1 and C2 and to achieve definitive surgical stabilisation. The anterior management of C2 fractures without C1-C2 fusion has the theoretical advantage that it preserves rotational motion at this motion segment and that the anterior approach is associated with lower morbidity. In the study presented here, we followed up a group of our patients who underwent anterior miniplate fixation for C2 fractures. METHODS: Fifteen patients underwent fixation of C2 fractures with titanium miniplates (Medartis Hand fixation system, 2.0 or 2.3 mm) that were placed using a submental approach. To our knowledge, this construct has not yet been described in the literature. Where necessary, this procedure was combined with screw fixation of the dens as described by Bohler. We retrospectively analysed operative reports and medical records, evaluated the patients' health status using the Short Form (36) Health Survey (SF-36), and performed clinical follow-up examinations. RESULTS: From January 2009 to June 2015, 226 traumatic lesions of the cervical spine were managed at our institution in the inpatient setting. Ninety-two patients underwent conservative treatment. Of the 134 cases that required surgery for fractures and instability, 67 involved the C0-C3 motion segments. In 15 patients, stability was achieved using an anterior miniplate or miniscrews alone (n = 4) or in addition to other techniques (n = 11). Anderson and D'Alonzo type II and III dens fractures with involvement of the body or lateral mass of C2 accounted for eight cases. Effendi type II body fractures with or without instability were seen in four cases. There was no perioperative mortality and morbidity in this patient group. All fractures healed and stability was achieved in all cases. No patient had neurological deficits or required revision surgery. An assessment of postoperative quality of life showed that 11 patients (7 men, 4 women) with a mean age of 57 (+/- 5.3) years reached an SF-36 score that was normal for their age group after a mean period of 33 (+/- 6.3) months following their injury. Compared to a group of healthy subjects, the patients had a range of motion that was limited only at the extremes. CONCLUSIONS: In patients with appropriate indications, anterior fixation with miniplates alone or additionally is a further useful treatment option in the management of fractures at the junction of the dens with the vertebral body of C2. Since this type of treatment preserves motion at the C1-C2 motion segment after fracture healing and since an anterior approach is associated with less surgical trauma than posterior instrumentation, the technique presented here should be included in a discussion on (surgical) treatment options.

PMID- 29572738 TI - Staged insertion of growing rods in severe scoliosis. AB - PURPOSE: The objective of this retrospective chart and radiographic review was to present the clinical outcomes and complication rate of a staged approach to modern dual growing-rod (GR) surgery when treating children with severe early onset scoliosis. METHODS: Fifteen patients received a 6-mm dual GR system. During Stage 1, pairs of end vertebra were exposed in a subperiosteal fashion, instrumented, grafted, and fused. Stage 2 was performed, on average, 5 months later (range 8-35 weeks) and the fused foundations were connected with two growing rods under skull-femoral traction. Clinical and operative notes were reviewed and all complications were recorded. Radiographic measurements were assessed at pre-index, with intraoperative traction during Stage 1, post-Stage 2 and at most recent follow-up. Statistical analyses were performed to evaluate change in scoliosis and kyphosis. RESULTS: At initial surgery, the average age was 8.17 +/- 1.5 years. The mean Cobb angle was 88.1 degrees +/- 14.0 degrees , corrected to 60.3 degrees +/- 8.7 degrees (p < 0.001) with intraoperative traction in Stage 1, preserved after Stage 2 instrumentation (59.5 degrees +/- 9.6 degrees , p = 0.69), and maintained with subsequent lengthenings (60.6 degrees +/- 12.8 degrees , p = 0.73). Hyperkyphosis (11/15 patients) improved from 70.8 degrees +/- 15.7 degrees to 46.6 degrees +/- 9.7 degrees (p < 0.001). At minimum 2-year follow-up (range 24-80 months, mean 49.5), the complication rate was 14 (0.93 complications/patient), including 6 rod breakages, 6 superficial infections, and 2 deep infections. No anchor migration or pull-out was noted. Seven patients have undergone definitive posterior spinal fusion. CONCLUSIONS: Staged insertion of dual GR systems permits strong distraction, with acceptable correction of severe deformities and minimal complications.

AB - PURPOSE: The optimal surgical timeframe for neurological recovery in traumatic spinal cord injury (tSCI) still remains unknown. Recent guidelines have recommended performing surgery within 24 h for all patients with tSCI regardless of initial neurological deficit. It remains unclear whether patients with complete, incomplete tSCI, or traumatic central cord injury (TCCI) will experience the same degree of improvement after urgent surgical intervention. We investigated if the severity of initial neurological injury influenced surgeons on their decision-making of surgical timing in tSCI. METHODS: With a web-based survey, we investigated the current opinion in The Netherlands on timing of surgical decompression and stabilization, depending on the initial degree of neurological injury. RESULTS: Surgeons prefer to perform more urgent surgery for incomplete tSCI compared to complete tSCI. In addition, 43% of patients with complete tSCI are not preferably operated within the recommended 24 h. Even though TCCI is the most common form of incomplete tSCI, these patients are preferably managed less urgently than patients with other types of incomplete tSCI. CONCLUSION: The severity of initial neurological injury seems to play an important role in the urgency of surgical timing for tSCI. A substantial number of patients with complete tSCI are not preferably treated within the recommended surgical timeframe, while patients with incomplete tSCI are preferably operated far more urgent than recommended in the current guidelines.

PMID- 29572741 TI - Active methods of mercury removal from flue gases. AB - Due to its adverse impact on health, as well as its global distribution, long atmospheric lifetime and propensity for deposition in the aquatic environment and in living tissue, the US Environmental Protection Agency (US EPA) has classified mercury and its compounds as a severe air quality threat. Such widespread presence of mercury in the environment originates from both natural and anthropogenic sources. Global anthropogenic emission of mercury is evaluated at 2000 Mg year-1. According to the National Centre for Emissions Management (Pol. KOBiZE) report for 2014, Polish annual mercury emissions amount to approximately 10 Mg. Over 90% of mercury emissions in Poland originate from combustion of coal.The purpose of this paper was to understand mercury behaviour during sub bituminous coal and lignite combustion for flue gas purification in terms of reduction of emissions by active methods. The average mercury content in Polish sub-bituminous coal and lignite was 103.7 and 443.5 MUg kg-1. The concentration of mercury in flue gases emitted into the atmosphere was 5.3 MUg m-3 for sub bituminous coal and 17.5 MUg m-3 for lignite. The study analysed six low-cost sorbents with the average achieved efficiency of mercury removal from 30.6 to 92.9% for sub-bituminous coal and 22.8 to 80.3% for lignite combustion. Also, the effect of coke dust grain size was examined for mercury sorptive properties. The fine fraction of coke dust (CD) adsorbed within 243-277 MUg Hg kg-1, while the largest fraction at only 95 MUg Hg kg-1. The CD fraction < 0.063 mm removed almost 92% of mercury during coal combustion, so the concentration of mercury in flue gas decreased from 5.3 to 0.4 MUg Hg m-3. The same fraction of CD had removed 93% of mercury from lignite flue gas by reducing the concentration of mercury in the flow from 17.6 to 1.2 MUg Hg m-3. The publication also presents the impact of photochemical oxidation of mercury on the effectiveness of Hg vapour removal during combustion of lignite. After physical oxidation of Hg in the flue gas, its effectiveness has increased twofold. PMID- 29572742 TI - Detection of the natural origin hydrocarbon contamination in carbonate aquifers (central Apennine, Italy). AB - The water-rock interaction is discussed in this study for some Central Apennine aquifers and their relative springs, where the geological and hydrogeological setting is potentially responsible for hydrocarbon contamination. The contamination is related to the presence of limestone formations with high organic content that are connected to the genesis of hydrocarbons in the Central Southern Apennines. Thanks to a multidisciplinary approach based on a seasonal monitoring of hydrogeological, hydrogeochemical, organic chemical, and isotopic variables, and to a detailed geological analysis, it was possible to demonstrate that the bituminous schists within the bituminous dolomite formation (a Triassic Formation presents in the Gran Sasso acquifer), the bituminous intercalations within the Bolognano Formation (an Olocenic calcareous Formation in the Majella acquifer), and the petroleum-saturated rocks of the Bolognano Formation (in the Morrone acquifer) are all able to leach hydrocarbons into groundwater. The results suggest that more detailed studies are required for areas where lithologies with fossil organic components are present. Insights should further investigate the interaction between groundwater and rocks in terms of organic compounds as well as inorganic compounds. In particular, the study also suggests that the supplementary quantification of hydrocarbon compounds in bituminous rock and the leaching tests are analyses that provide reliable results. From the normative point of view, the results of the study can be useful when dealing with hydrocarbon contamination resulting from anthropogenic activities within catchments where formations with high concentration of organic matter are present. In these cases, it will possible to assess the natural background concentrations and review the threshold values upwards.

AB - Spatial interpolation method is the basis of soil heavy metal pollution assessment and remediation. The existing evaluation index for interpolation accuracy did not combine with actual situation. The selection of interpolation methods needs to be based on specific research purposes and research object characteristics. In this paper, As pollution in soils of Beijing was taken as an example. The prediction accuracy of ordinary kriging (OK) and inverse distance weighted (IDW) were evaluated based on the cross validation results and spatial distribution characteristics of influencing factors. The results showed that, under the condition of specific spatial correlation, the cross validation results of OK and IDW for every soil point and the prediction accuracy of spatial distribution trend are similar. But the prediction accuracy of OK for the maximum and minimum is less than IDW, while the number of high pollution areas identified by OK are less than IDW. It is difficult to identify the high pollution areas fully by OK, which shows that the smoothing effect of OK is obvious. In addition, with increasing of the spatial correlation of As concentration, the cross validation error of OK and IDW decreases, and the high pollution area identified by OK is approaching the result of IDW, which can identify the high pollution areas more comprehensively. However, because the semivariogram constructed by OK interpolation method is more subjective and requires larger number of soil samples, IDW is more suitable for spatial prediction of heavy metal pollution in soils. PMID- 29572744 TI - Ameliorative effects of nano-elemental selenium against hexavalent chromium induced apoptosis in broiler liver. AB - The current study examined the ameliorative effects of nano-elemental selenium (Nano-Se) against chromium-VI (K2Cr2O7)-induced apoptosis in chickens. The expression of apoptosis-related genes was evaluated by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot. A total of 60, one-day-old broiler chickens allotted to six equal groups, i.e., control group (standard diet), Cr(VI)-exposed group (K2Cr2O7 via drinking water), Nano-Se group (Nano-Se at 0.5 mg/kg via diet), protection group (K2Cr2O7 + Nano-Se), cure group (K2Cr2O7 for initial 2 weeks and then Nano-Se), and prevention group (opposite to the cure group) and were detected by the activities of pro-apoptosis (Bax, Caspase-3) and anti-apoptosis (Bcl-2) genes expression at day 35 of the experiment. Intense apoptosis was observed in liver tissues of chickens exposed to K2Cr2O7. The Nano-Se supplementation caused a significant decrease (P < 0.01) in the mRNA expression levels of Bax and Caspase-3 genes, while significantly elevated (P < 0.05) mRNA expression level of Bcl-2 gene was observed in Nano-Se experimental groups as compare to control and Cr(VI)-exposed group. The results quantified by the RT-qPCR were further confirmed by the western blot analysis. Altogether, these results suggest anti-apoptotic effects of Nano-Se in the chicken liver, which is interesting for further study. The present findings suggested that Nano-Se has protective effects against K2Cr2O7-induced apoptosis in broilers liver and can serve a key role as a protective agent against apoptosis. PMID- 29572745 TI - Assessment of neurohepatic DNA damage in male Sprague-Dawley rats exposed to organophosphates and pyrethroid insecticides. AB - The current work was undertaken to test the genotoxic potential of chlorpyrifos (CPF), dimethoate, and lambda cyhalothrin (LCT) insecticides in rat brain and liver using the single cell gel electrophoresis (comet assay). Three groups of adult male Sprague-Dawley rats were exposed orally to one third LD50of CPF, dimethoate, or LCT for 24 and 48 h while the control group received corn oil. Serum samples were collected for estimation of malondialdehyde (MDA) and glutathione peroxidase (GPx); the brain and liver samples were used for comet assay and for histopathological examination. Results showed that signs of neurotoxicity appeared clinically as backward stretching of hind limb and splayed gait in dimethoate and LCT groups, respectively. CPF, LCT, and dimethoate induced oxidative stress indicated by increased MDA and decreased GPx levels. CPF and LCT caused severe DNA damage in the brain and liver at 24 and 48 h indicated by increased percentage of DNA in tail, tail length, tail moment, and olive tail moment. Dimethoate induced mild DNA damage in the brain and liver at 48 h. Histopathological changes were observed in the cerebrum, cerebellum, and liver of exposed rats. The results concluded that CPF, LCT, and dimethoate insecticides induced oxidative stress and DNA damage associated with histological changes in the brain and liver of exposed rats. PMID- 29572746 TI - Computed tomography pulmonary vascular volume ratio in children and young adults with congenital heart disease: the effect of cardiac phase. AB - BACKGROUND: The effect of cardiac phase on CT pulmonary vascular volumetry is unknown. OBJECTIVE: To evaluate the effect of cardiac phase on CT pulmonary vascular volume ratio in children and young adults with congenital heart disease. MATERIALS AND METHODS: Thirty-one children and young adults (median age 14 years) with congenital heart disease underwent electrocardiography-synchronized cardiothoracic CT at the end-systolic and end-diastolic phases as well as lung perfusion scintigraphy (n=20) or cardiac MRI (n=11). The author calculated right and left pulmonary vascular volumes by using threshold-based CT volumetry. Right pulmonary vascular volume percentages measured by CT obtained at the end-systolic and end-diastolic phases were compared with corresponding values measured by the reference method (lung perfusion scintigraphy or phase-contrast MRI) by using paired t-test and Bland-Altman analysis. RESULTS: The right pulmonary vascular volume percentages measured by CT were significantly greater at the end-systolic phase than at the end-diastolic phase (64.0+/-14.1% vs. 61.9+/-10.7%; P<0.01). The end-systolic CT right pulmonary vascular volume percentages were not significantly different from the corresponding values measured by the reference method (64.0+/-14.1% vs. 65.3+/-13.6%; P>0.05), while the end-diastolic vascular volume percentages were significantly smaller than the corresponding values measured by the reference method (61.9+/-10.7% vs. 65.3+/-13.6%; P=0.01). Bland Altman analysis showed a mean difference of 1.4+/-7.2% for the end-systolic CT, which was significantly smaller than that for the end-diastolic CT (3.4+/-7.0%; P<0.01). CONCLUSION: The CT pulmonary vascular volume ratio is significantly influenced by the cardiac phase of cardiothoracic CT. The end-systolic phase offers more accurate CT pulmonary vascular volumes than the end-diastolic phase. PMID- 29572747 TI - Severe nasomaxillary hypoplasia (Binder phenotype) on prenatal US/MRI: an important marker for the prenatal diagnosis of chondrodysplasia punctata. AB - BACKGROUND: Chondrodysplasia punctata is a skeletal dysplasia caused by a diverse spectrum of etiologies, with outcomes ranging from antenatal demise to a normal life span. Prenatal detection can be challenging. OBJECTIVE: To review a series of cases of chondrodysplasia punctata associated with nasomaxillary hypoplasia, known as the Binder phenotype, and to highlight prenatal ultrasound and MRI findings, as well as postnatal MRI and radiographic findings. MATERIALS AND METHODS: We retrospectively reviewed ultrasound, MRI and radiographic imaging findings in postnatally confirmed cases of chondrodysplasia punctata from 2001 to 2017. We analyzed prenatal findings and correlated them with maternal history, postnatal imaging, phenotype, genetics and outcome. RESULTS: We identified eight cases, all with prenatal US and six of eight with prenatal MRI between 18 weeks and 32 weeks of gestational age. Reasons for referral included midface hypoplasia in four cases; family history in one case; intrauterine growth restriction in one case; short long-bones, intrauterine growth restriction and multicystic kidney in one case; and multiple anomalies in one case. In six cases, postnatal radiographs were performed. In four cases, postnatal spine MRI imaging was performed. The diagnosis of chondrodysplasia punctata was suggested in prenatal reports in six of eight fetuses. Seven of eight fetuses had Binder phenotype with severe nasomaxillary hypoplasia. Limb length was mildly symmetrically short in four of eight cases and normal in four of eight fetuses. Two of eight fetuses had epiphyseal stippling identified prenatally by US; this was present postnatally in six neonates on radiographs. Hand and foot abnormalities of brachytelephalangy were not detected on the prenatal US or MRI but were present in six of eigth fetuses on postnatal radiographs or physical exam. Four of eight fetuses had prenatal spine irregularity on US from subtle stippling. Six of eight had spine stippling on postnatal radiographs. One fetus had cervicothoracic kyphosis on prenatal US and MRI, and this was postnatally present in one additional neonate. One case had prenatally suspected C1 spinal stenosis with possible cord compression, and this was confirmed postnatally by MRI. There was a maternal history of systemic lupus erythematosus in two and hyperemesis gravidarum in one. Outcomes included one termination and seven survivors. CONCLUSION: Chondrodysplasia punctata can be identified prenatally but findings are often subtle. The diagnosis should be considered when a fetus presents with a hypoplastic midface known as the Binder phenotype. Maternal history of lupus, or other autoimmune diseases or hyperemesis gravidarum can help support the diagnosis. PMID- 29572748 TI - The role of complement components C1q, MBL and C1 inhibitor in pathogenesis of endometriosis. AB - PURPOSE: The purpose of the work was to evaluate possible associations between the complement components C1q, mannose-binding lectin (MBL) and C1 inhibitor (C1INH) with pathogenesis of endometriosis. METHODS: Concentrations of C1q, MBL and C1INH were measured by ELISA in peritoneal fluid (PF) in 80 women with or without endometriosis. RESULTS: Significantly higher PF levels of C1q, MBL and C1INH in women with endometriosis compared to control group were observed (p < 0.0001). A higher concentration of the studied parameter was found in PF of women at the early stage of the disease, as compared to women with advanced endometriosis (p < 0.0001). CONCLUSIONS: Our research suggests that in the peritoneal cavity in women with endometriosis there are abnormal regulations of both the classical and lectin pathways of the complement system. This can suggest impairments in purification of peritoneal cavity from ectopic endometrial cells and augmented local inflammation in endometriosis patients. PMID- 29572750 TI - The size of the renal artery orifice contributes to laterality of acute renal infarction. AB - BACKGROUND: Acute renal infarction (ARI) is a rare disease with atrial fibrillation being its main cause. The possible laterality of ARI is controversial. This study aimed to evaluate the association between anatomical features of the renal arteries and ARI. METHODS: This was a single-center cross sectional study that evaluated the anatomical and clinical features of renal arteries. The anatomical features of the renal arteries were assessed using computed tomography. RESULTS: A total of 46 patients (mean age 71.3 +/- 14.0 years; men, 59%) were enrolled. ARI involved the left kidney in 63%, right kidney in 28%, and both kidneys in 9% of patients. The right renal artery orifice was often higher than that of the left renal artery (71%). The angle of divergence from the abdominal aorta was similar on both sides. The left renal artery orifice was larger than that of the right (83 +/- 24, 72 +/- 24 mm2; p = 0.03, respectively). A larger left orifice was present in 72% of all cases. ARI involved the side with the larger orifice in 64% of patients. CONCLUSION: The size of the renal artery orifice may be a factor that contributes to the laterality of ARI. Assessment of anatomical features is important when considering the laterality of the disease. PMID- 29572749 TI - Eculizumab treatment in severe pediatric STEC-HUS: a multicenter retrospective study. AB - BACKGROUND: Hemolytic uremic syndrome related to Shiga-toxin-secreting Escherichia coli infection (STEC-HUS) remains a common cause of acute kidney injury in young children. No specific treatment has been validated for this severe disease. Recently, experimental studies highlight the potential role of complement in STEC-HUS pathophysiology. Eculizumab (EC), a monoclonal antibody against terminal complement complex, has been used in severe STEC-HUS patients, mostly during the 2011 German outbreak, with conflicting results. METHODS: On behalf of the French Society of Pediatric Nephrology, we retrospectively studied 33 children from 15 centers treated with EC for severe STEC-HUS. Indication for EC was neurologic involvement in 20 patients, cardiac and neurologic involvement in 8, cardiac involvement in 2, and digestive involvement in 3. Based on medical status at last follow-up, patients were divided into two groups: favorable (n = 15) and unfavorable outcomes (n = 18). RESULTS: Among patients with favorable outcome, 11/14 patients (79%) displayed persistent blockade of complement activity before each EC reinjection. Conversely, in patients with unfavorable outcome, only 9/15 (53%) had persistent blockade (p = n.s.). Among 28 patients presenting neurological symptoms, 19 had favorable neurological outcome including 17 with prompt recovery following first EC injection. Only two adverse effects potentially related to EC treatment were reported. CONCLUSIONS: Taken together, these results may support EC use in severe STEC-HUS patients, especially those presenting severe neurological symptoms. The study, however, is limited by absence of a control group and use of multiple therapeutic interventions in treatment groups. Thus, prospective, controlled trials should be undertaken. PMID- 29572751 TI - Operator Experience and Outcomes After Left Main Percutaneous Coronary Intervention. AB - PURPOSE OF REVIEW: This review was performed with the goal of summarizing the role of operator experience in the treatment of severe left main stenosis by percutaneous intervention techniques. RECENT FINDINGS: The Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial demonstrated that percutaneous coronary intervention and coronary artery bypass grafting had similar clinical outcomes for severe left main disease. However, PCI of the left main coronary stenosis is considered to be a high-risk intervention because of the large area of myocardium at jeopardy that can quickly cause hemodynamic compromise. Operator experience and familiarity with the use of hemodynamic support devices, plaque modification techniques, and intravascular imaging tools is associated with better clinical outcomes. In patients with severe left main stenosis undergoing percutaneous coronary intervention by high-volume operators, the clinical outcomes are superior. PMID- 29572752 TI - Development of a Smart Mobile Data Module for Fetal Monitoring in E-Healthcare. AB - The fetal heart rate (FHR) is a marker of fetal well-being in utero (when monitoring maternal and/or fetal pathologies) and during labor. Here, we developed a smart mobile data module for the remote acquisition and transmission (via a Wi-Fi or 4G connection) of FHR recordings, together with a web-based viewer for displaying the FHR datasets on a computer, smartphone or tablet. In order to define the features required by users, we modelled the fetal monitoring procedure (in home and hospital settings) via semi-structured interviews with midwives and obstetricians. Using this information, we developed a mobile data transfer module based on a Raspberry Pi. When connected to a standalone fetal monitor, the module acquires the FHR signal and sends it (via a Wi-Fi or a 3G/4G mobile internet connection) to a secure server within our hospital information system. The archived, digitized signal data are linked to the patient's electronic medical records. An HTML5/JavaScript web viewer converts the digitized FHR data into easily readable and interpretable graphs for viewing on a computer (running Windows, Linux or MacOS) or a mobile device (running Android, iOS or Windows Phone OS). The data can be viewed in real time or offline. The application includes tools required for correct interpretation of the data (signal loss calculation, scale adjustment, and precise measurements of the signal's characteristics). We performed a proof-of-concept case study of the transmission, reception and visualization of FHR data for a pregnant woman at 30 weeks of amenorrhea. She was hospitalized in the pregnancy assessment unit and FHR data were acquired three times a day with a Philips Avalon(r) FM30 fetal monitor. The prototype (Raspberry Pi) was connected to the fetal monitor's RS232 port. The emission and reception of prerecorded signals were tested and the web server correctly received the signals, and the FHR recording was visualized in real time on a computer, a tablet and smartphones (running Android and iOS) via the web viewer. This process did not perturb the hospital's computer network. There was no data delay or loss during a 60-min test. The web viewer was tested successfully in the various usage situations. The system was as user-friendly as expected, and enabled rapid, secure archiving. We have developed a system for the acquisition, transmission, recording and visualization of RCF data. Healthcare professionals can view the FHR data remotely on their computer, tablet or smartphone. Integration of FHR data into a hospital information system enables optimal, secure, long-term data archiving. PMID- 29572754 TI - Development of Whey Protein Concentrate-Pectin-Alginate Based Delivery System to Improve Survival of B. longum BL-05 in Simulated Gastrointestinal Conditions. AB - Bifidobacterium longum BL-05 encapsulated beads were developed by using whey protein concentrate (WPC) and pectin (PE) as encapsulating material through extrusion/ionic gelation technique with the objective to improve survival of probiotics in harsh gastrointestinal conditions. B. longum BL-05 was grown in MRS (de man rogosa and sharpe) broth, centrifuged and mixed with polymeric gel solution. Bead formulations E4 (2.5% WPC + 1.5% PE) and E5 (2% PE) showed the highest value for encapsulation efficiency, size, and textural properties (hardness, cohesiveness, springiness) due to increasing PE concentration. The survivability and viability of free and encapsulated B. longum BL-05 was assessed through their resistance to simulated gastric juice (SGJ), tolerance to bile salt, release profile in simulated intestinal fluid (SIF), and storage stability during 28 days at 4 degrees C. The microencapsulation provided protection to B. longum BL-05 and encapsulated cells were exhibited significant (p < 0.05) resistance to SGJ and SIF as compared to free cells. Bead formulations E3 (5.0% WPC + 1.0% PE) and E4 (2.5% WPC + 1.5% PE) exhibited more resistance to SGJ (at pH 2 for 2 h) and at 2% bile salt solution but comparatively slow release as compared to other bead formulations. Free cells lost their viability when stored at 4 degrees C after 28 days but microencapsulated cells demonstrated promising results during storage and viable cell count was > 107 CFU/g. This study revealed that extrusion using WPC and PE as encapsulating material could be considered as one of the novel technologies for protection and effective delivery of probiotics. PMID- 29572753 TI - How Do We Approach Benign Proliferative Lesions? AB - PURPOSE OF REVIEW: The aim of this review is to summarize recently published literature addressing atypical ductal hyperplasia (ADH), lobular neoplasia (atypical lobular hyperplasia [ALH] and classic lobular carcinoma in situ [C LCIS]), non-classic lobular carcinoma in situ (NC-LCIS), papillary lesions, and flat epithelial atypia (FEA). RECENT FINDINGS: While ADH, ALN, and C-LCIS are well-established markers of an increased risk of future breast cancers, the risk implications are less clear for papillary lesions and FEA. NC-LCIS is the least well-characterized lesion, with scant published literature on its natural history and surgical management when encountered on needle biopsy. Recent data suggest that lobular neoplasia on core biopsy of a BI-RADS <= 4 concordant lesion does not require an excision, while ADH, atypical papillomas, and NC-LCIS should be excised. Evidence on FEA and papillomas without atypia suggests a low risk of upgrade on excision, and prospective studies on the upgrade of these lesions are ongoing. PMID- 29572755 TI - Optimization of Nutrient Composition for Producing ACE Inhibitory Peptides from Goat Milk Fermented by Lactobacillus bulgaricus LB6. AB - Hypertension is a serious threat to human health and food-derived angiotensin converting enzyme (ACE; EC 3.4.15.1) inhibitory peptides can be used to regulate high blood pressure without side effects. The composition of the nutrient medium for the production of these peptides by fermenting goat milk with Lactobacillus bulgaricus LB6 was optimized to increase the ACE inhibitory activity by Box Behnken design (BBD) of response surface methodology (RSM) in the present study. Soybean peptone, glucose, and casein had significant effects on both ACE inhibition rate and viable counts of L. bulgaricus LB6 during incubation. The results showed that the maximum values of ACE inhibition rate and viable counts for L. bulgaricus LB6 were reaching to 86.37 +/- 0.53% and 8.06 * 107 under the optimal conditions, which were 0.35% (w/w) soybean peptone, 1.2% (w/w) glucose, and 0.15% (w/w) casein. The results were in close agreement with the model prediction. The optimal values of the medium component concentrations can be a good reference for obtaining ACE inhibitory peptides from goat milk. PMID- 29572756 TI - Contamination by lead in sediments at Toledo River, hydrographic basin of PARANA III. AB - Due to intense agricultural and industrial activities, the environment has been affected by increasing amounts of pollutants, such as lead, a toxic heavy metal. When introduced to the environment, toxic metals are distributed and incorporated into the liquid medium, sediments, and aquatic biota; bioaccumulating. This research aimed to identify and quantify the levels of toxic metals present in the waters and sediments of Toledo River, compare the obtained results with legislation and other studies, as well as to evaluate the possible pollutant sources of the water body. Six water and sediment samples were taken at seven strategic sites. The concentrations of Cu, Zn, Fe, Mn, Cd, Pb, and Cr in water were compared to the maximum limits established by Brazilian legislation IN CONAMA No. 357/05, for class II fresh waters. The sediment samples were submitted to nitroperchloric digestion, and then the total concentrations of the metals were determined by flame atomic absorption spectrometry (FAAS). The toxicological quality of the Toledo River has been considerably affected by the activities carried out in its surroundings, such as extensive areas of agriculture, pig farming and industrial areas, causing concentrations of Cd, Fe, and mainly Pb, which is observed at concentrations higher than value allowed by the legislation. PMID- 29572757 TI - [Pain is modality-specific : Differences in the perception and processing of interoceptive visceral compared to exteroceptive cutaneous heat pain stimuli]. AB - Interoceptive visceral pain is perceived as more fear-inducing and unpleasant compared to cutaneous heat pain in healthy women even when stimuli are matched for perceived pain intensity. On a neural level, both pain stimuli induce comparable neural activation in areas related to processing of sensory discriminative pain aspects. However, enhanced neural responses are observed in areas associated with salience processing and descending pain inhibition for the visceral pain modality, even when results are controlled for intra-individual differences in perceived pain intensity. Moreover, immanent fear of pain is suggested to play a distinctive role in perception of visceral pain. PMID- 29572758 TI - Does freedom make a difference? : An empirical investigation of differences between subjective well-being and perceived capabilities amongst cancer patients. AB - Perceived capabilities-a subjective operationalization of Sen's concept of capability-and subjective well-being are increasingly regarded as relevant information about individual well-being to guide resources allocation in healthcare. Although they refer to different notions, both types of measures rely on self-reported information and little is known as to how they compare together empirically. The aim of this paper is to investigate differences between measures of subjective well-being and of perceived capabilities in terms of their correlation with dimensions of health-related quality of life using panel data concerning a sample of 293 breast cancer and melanoma patients. Regression analyses suggest that the measures capture quite different aspects of the patients' welfare. Differences in the correlation with dimensions of health also seem consistent with the underlying notions to which these measures refer. However, our findings also suggest that future researches should aim at determining how measures of perceived capabilities may be influenced by individual personality traits.

AB - BACKGROUND: Pigmented and albino rabbits are commonly used in visual research; however, the lack of pigment in the eyes may affect retinal responses. Here, we compare and describe the differences of retinal function between pigmented (English Butterfly) and albino (New Zealand) rabbits. METHODS: Electroretinograms were recorded in pigmented and albino rabbits in the dark-adapted eye, in the light-adapted eye and for four temporal frequencies in the light-adapted eye. The implicit time and amplitude of the a- and b-waves were analyzed, as well as the amplitude and phase of the first harmonic component of the photopic flicker response. RESULTS: Albino rabbits presented significantly larger amplitudes for both a- and b-waves at all intensities and frequencies. The intensity-response function of the scotopic b-wave also showed that the albino retina is more sensitive than the pigmented retina and the larger flicker amplitudes found in the albino group also revealed post-receptoral changes specifically related to cone pathways. CONCLUSIONS: The larger amplitude of albino receptoral and post receptoral activities might be attributed to greater availability of light due to scatter and reflection at the retinal layer, and as the differences in response amplitudes between the groups increase with flicker frequency, we suggest that ON bipolar cells recover faster in the albino group, suggesting that this might be a mechanism to explain the higher temporal resolution for albinos compared to the pigmented group. PMID- 29572762 TI - Association of Depressive Symptoms with Lapses in Antiretroviral Medication Adherence Among People Living with HIV: A Test of an Indirect Pathway. AB - Viral suppression, a critical component of HIV care, is more likely when individuals initiate antiretroviral therapy (ART) early in disease progression and maintain optimal levels of adherence to ART regimens. Although several studies have documented the negative association of depressive symptoms with ART adherence, less is known about how depressed mood relates to intentional versus unintentional lapses in adherence as well as the mechanisms underlying this association. The purpose of the current study was to examine the association of depressive symptoms with ART adherence, assessed as a multidimensional construct. Secondarily, this study conducted preliminary indirect path models to determine if medication self-efficacy could explain the depressed mood-adherence relationship. Depressive symptoms were not associated with 95% ART taken, self reported viral load, deliberate adjustments to ART regimens or skipped ART doses. However, the indirect association of depressive symptoms via decrements in medication self-efficacy was significant for 95% ART taken, self-reported viral load and skipped ART doses, but not deliberate changes to ART regimens. In this sample of HIV-positive outpatients, there is evidence to support medication self efficacy as a potential mechanism underlying the association between depressive symptoms and ART adherence. Additional longitudinal studies are needed to formally examine medication taking self-efficacy as a mediator.

AB - OBJECTIVE: The aim of this study was to reveal the efficacy of weekly administration of paclitaxel and carboplatin for advanced ovarian cancer patients with poor performance status (PS). METHODS: FIGO stage III/IV ovarian cancer or fallopian tube cancer patients who underwent interval debulking surgery (IDS) followed by neoadjuvant chemotherapy (NAC) were analyzed retrospectively. Patients were divided into two groups based on NAC: weekly paclitaxel and carboplatin (W-TC) and 3 weeks of paclitaxel and carboplatin (TW-TC). Toxicity, efficacy of NAC, surgery outcome, and prognosis were assessed by comparing the two groups. RESULTS: Twenty patients treated with W-TC and 18 patients treated with TW-TC were analyzed. All of the W-TC patients were poor PS (PS >= 2), and all of the TW-TC patients were good PS (PS <= 1). The overall clinical response rates were 70% in W-TC and 83.4% in TW-TC. In the W-TC group, Grade 3/4 anemia and thrombocytopenia and greater than grade 2 neuropathy were significantly reduced compared to TW-TC patients. A frequency of treatment delay greater than 7 and 14 days, G-CSF support, blood transfusion, and dose reduction or regimen change were also significantly reduced in the W-TC group. The rate of IDS, optimal debulking surgery, complications during operation, and blood transfusion were similar between the W-TC and TW-TC groups. Progression-free survival and overall survival were also similar between the two groups. CONCLUSION: Our study suggested that NAC with W-TC for poor PS patients with non-treated ovarian cancer reduced the toxicity of chemotherapy and had the same efficacy as TW-TC.

AB - PURPOSE OF REVIEW: The purpose of this review is to describe the role of device utilization as a component of surveillance for healthcare-associated infections and describe its potential role as a measurement of healthcare quality. RECENT FINDINGS: Device utilization, while primarily a process-based measure in the prevention of device-associated infections can also serve as an important outcome in the evaluation of an infection prevention program. Device utilization can be an important and resource-efficient measurement when coupled with measurements of risk-adjusted infection rates. The measurement of the device utilization ratio can provide insight into the risk of device-associated harms, including non infectious harms, which would not be captured with currently used infection-based surveillance metrics. Further study and validation of standardized, risk-adjusted device utilization measurements is an important area for future exploration. PMID- 29572766 TI - CD3+ CD56+ EBER1+ atypical extraosseous plasmacytoma of the nasal cavity. AB - We present a case of atypical extraosseous plasmacytoma (EP) with a plasmablastic morphology and CD3+ CD56+ Epstein-Barr virus-encoded RNA-1 (EBER1)+ phenotypes of the nasal cavity. A 51-year-old male attended a local hospital with a tumor located in his left nasal cavity that was histologically diagnosed as extranodal NK/T cell lymphoma, nasal type. We reviewed the specimens and re-biopsied the tumor, and confirmed that the tumor was positive for CD3, CD56, and EBER1; however, the tumor showed a plasmablastic morphology without necrosis and angiocentricity, and was positive for CD138, but negative for CD20 and PAX5. Given a plasmablastic morphology and EBER1 positivity, but a relatively low Ki67 index (30%), we diagnosed the case as atypical EP. The CHOP regimen was administered and complete remission achieved. This case indicated that EP should be considered as a differential diagnosis even when a tumor shows large cell morphology and is positive for CD3, CD56, and EBER1. PMID- 29572765 TI - Standardizing procedures improves and homogenizes short-term outcomes after minimally invasive esophagectomy. AB - PURPOSE: Esophageal cancer is one of the deadliest cancers worldwide. Esophagectomy with lymphadenectomy is regarded as the only curative option for resectable esophageal cancer, but it is associated with high morbidity and mortality. Multidisciplinary team (MDT) management was recently associated with improved outcomes after surgery for esophageal cancer. The aim of this study was to investigate the effect of standardizing procedures for minimally invasive esophagectomy (MIE) in the MDT setting. METHODS: This was a case-matched control study of 154 patients with esophageal cancer who underwent thoracoscopic esophagectomy in the prone position (TEP) between 2012 and 2016. Surgery was performed by two attending surgeons (surgeons A and B) who began working together in the same MDT in 2015. At that time, the following surgical procedures were standardized between surgeons A and B: mediastinal lymphadenectomy, abdominal procedures, and estimation of the blood supply of the gastric conduit. Short-term outcomes were compared between the following paired groups using propensity scores: surgeon A's pre- and post-standardization groups, surgeon B's pre- and post-standardization groups, and surgeon A's post-standardization group and surgeon B's post-standardization group. RESULTS: Concerning surgeon A, the estimated total blood loss in the post-standardization group (142 +/- 87 mL) was significantly lower than that in the pre-standardization group (376 +/- 215 mL, P = 0.006). The rate of left recurrent laryngeal nerve palsy in the post standardization group (13%) was significantly lower than that in the pre standardization group (47%, P = 0.046). Concerning surgeon B, the rate of anastomotic leakage in the post-standardization group (0%) was significantly lower than that in the pre-standardization group (11%, P = 0.039). Comparing the post-standardization groups of surgeons A and B, there were no significant differences in operative outcomes or morbidity. CONCLUSIONS: Standardizing procedures for MIE improved and homogenized surgical short-term outcomes. PMID- 29572767 TI - The impact of photobiomodulation on osteoblast-like cell: a review. AB - In this study, we present a review of the literature on the impact of photobiomodulation on osteoblast-like cell culture. Searches were performed in the PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online), SCOPUS, and SPIE digital library databases for original articles regarding the effects of LLLT on osteoblast-like cells in experimental models using LLLT published in English from the last 20 years. The search identified 1439 studies. After the analysis of the abstracts, 1409 studies were excluded and 30 studies were then selected for the full-text analysis, 8 of which were excluded. Thus, 22 studies were included for a critical evaluation of the impact of photobiomodulation on osteoblast-like cell culture. The cell lineages studied were primary rat, primary human, saos-2, Osteo-1, MC3T3, MG63, and OFCOL II. Moreover, a wide variety of experimental models were used to experimentally analyze the impact of photobiomodulation, the most common of which were alkaline phosphatase, MTT, and cell count. This review suggests that osteoblastic-like cells are susceptible to photobiomodulation but that most of the light parameters varied by different authors have little to no influence on proliferation but very high levels of irradiance have demonstrated deleterious effects on proliferation, highlighting the bi-phasic effect of photobiomodulation.

AB - The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has played an integral role in educating both the metabolic surgical and the medical community at large about the role of innovative and new surgical and or endoscopic interventions in treating adiposity-based chronic diseases. The single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is also called the one anastomosis duodenal switch (OADS). This is a relatively new procedure that has been proposed as an alternative to the currently accepted duodenal switch (DS) procedure. The IFSO commissioned a task force (Appendix 1) to determine if SADI-S/OADS is an effective and safe procedure and if it should be considered a surgical option for the treatment of adiposity and adiposity based chronic diseases. The following position statement is issued by the IFSO SADI-S/OADS task force and approved by the IFSO Executive Board. This statement is based on current clinical knowledge, expert opinion and published peer reviewed scientific evidence. It will be reviewed in 2 years.

PMID- 29572768 TI - Candidemia in Adults at a Tertiary Hospital in China: Clinical Characteristics, Species Distribution, Resistance, and Outcomes. AB - BACKGROUND: Candidemia is one of the most common nosocomial bloodstream infections. Early diagnosis and antifungal treatment improve clinical outcomes in some studies but not all, with diverse data reported from different institutions. Similarly, antifungal resistance is more common in the USA than in Europe, but there is little data regarding the microbiology and clinical course of candidemia in adult patients in Asia. AIMS: (1) To capture species distribution and drug resistance rates among Candida bloodstream isolates, (2) to describe clinical features of candidemia, and (3) to identify factors associated with all-cause mortality, with emphasis on early initiation of antifungal treatment, at a large tertiary University Hospital in China. METHODS: In this single-center retrospective study, we identified all patients with candidemia, between 2008 and 2014. Demographic and clinical characteristics, microbiological information, details of antifungal therapy and clinical outcomes were collected. RESULTS: We studied 166 patients. 71 (42.8%) had cancer. Candida albicans was the most frequent species (37.3%), followed by C. parapsilosis (24.1%), C. tropicalis (22.8%), and C. glabrata (14.5%). Antifungal resistance was more frequent in non albicans strains and especially C. glabrata. Twenty patients received inappropriate treatment with all-cause mortality of 35%. The remaining 146 patients had significantly lower mortality (21.9%, P = 0.045). Among patients who received antifungal treatment, mortality rate increased with time to appropriate antifungal therapy (AAT): 13.7%, for < 24 h, 21.1% for 24-48 h, 23.1% for > 48 h, and 32.4% among patients who received no AT (chi2 for trend P = 0.039). Initiating AAT more than 24 h after blood culture collection was an independent risk factor for mortality, after adjustment for other confounders (OR 7.1, 95% CI 1.3-39.4, P = 0.024). CONCLUSIONS: Candida albicans was the most frequent cause of candidemia at a large tertiary hospital in China, but antifungal resistance is a growing concern among non-albicans Candida species. The mortality rate of patients treated with ineffective antifungal agents based on in vitro susceptibilities was similar to that of patients who received no treatment at all, and delayed initiation of antifungal treatment was associated with increased risk of death.

AB - Habitual consumption of chlorogenic acid compounds (CGAs) from coffee increases fat catabolism and reduces body fat; however, the contribution of roasted coffee remains unclear. Hydroxyhydroquinone (HHQ) impairs the vasodilatory and antihypertensive effects of CGAs by reducing nitric oxide (NO) bioavailability. Since HHQ also reduces fat catabolism, we hypothesized that HHQ does so by decreasing NO availability. Therefore, we investigated the effect of HHQ on energy metabolism in KKAy mice. In HHQ-treated mice, fat oxidation was significantly low and dose-dependent, serum and urinary hydrogen peroxide were high, and plasma NO metabolites and S-nitrosylated liver proteins were low. In HHQ-treated mouse hepatocytes, the palmitate-induced increase in cellular oxygen consumption was negatively affected, and HHQ or L-NAME reduced cellular fatty acid utilization. In conclusion, HHQ can impair fat utilization by reducing NO availability in mice. Protein S-nitrosylation reduction in liver cells after HHQ consumption may be associated with impaired fatty acid oxidation. PMID- 29572771 TI - Brain functional connectivity correlates of coping styles. AB - Coping abilities represent the individual set of mental and behavioral strategies adopted when facing stress or traumatic experiences. Coping styles related to avoidance have been linked to a disposition to develop psychiatric disorders such as PTSD, anxiety, and major depression, whereas problem-oriented coping skills have been positively correlated with well-being and high quality of life. Even though coping styles constitute an important determinant of resilience and can impact many aspects of everyday living, no study has investigated their brain functional connectivity underpinnings in humans. Here we analyzed both psychometric scores of coping and resting-state fMRI data from 102 healthy adult participants. Controlling for personality and problem-solving abilities, we identified significant links between the propensity to adopt different coping styles and the functional connectivity profiles of regions belonging to the default mode (DMN) and anterior salience (AS) networks-namely, the anterior cingulate cortex, left frontopolar cortex, and left angular gyrus. Also, a reduced negative correlation between AS and DMN nodes explained variability in one specific coping style, related to avoiding problems while focusing on the emotional component of the stressor at hand, instead of relying on cognitive resources. These results might be integrated with current neurophysiological models of resilience and individual responses to stress, in order to understand the propensity to develop clinical conditions (e.g., PTSD) and predict the outcomes of psychotherapeutic interventions. PMID- 29572773 TI - Traditions, Paradigms and Basic Concepts in Islamic Psychology. AB - The conceptual tools of psychology aim to explain the complexity of phenomena that psychotherapists observe in their patients and within themselves, as well as to predict the outcome of therapy. Naturally, Muslim psychologists have sought satisfaction in the conceptual tools of their trade and in what has been written in Islamic psychology-notably by Badri (The dilemma of Muslim psychologists, MWH London, London, 1979), who critiqued Western psychology from an Islamic perspective, arguing the need to filter out from Western Psychology which was cross-culturally invalid or was in conflict with Islamic precept. In this paper, I advocate an extension of Badri's (1979) approach and present a working model of the self derived from traditional Islamic thought. This model, though rudimentary and incomplete, I believe, makes better sense of my perceptions as a clinician than any other psychological model within my knowledge. PMID- 29572774 TI - Identification, Characterization, and Mapping of a Novel SNP Associated with Body Color Transparency in Juvenile Red Sea Bream (Pagrus major). AB - We previously reported a body color deformity in juvenile red sea bream, which shows transparency in the juvenile stage because of delayed chromatophore development compared with normal individuals, and this finding suggested a genetic cause based on parentage assessments. To conduct marker-assisted selection to eliminate broodstock inheriting the causative gene, developing DNA markers associated with the phenotype was needed. We first conducted SNP mining based on AFLP analysis using bulked-DNA from normal and transparent individuals. One SNP was identified from a transparent-specific AFLP fragment, which significantly associated with transparent individuals. Two alleles (A/G) were observed in this locus, and the genotype G/G was dominantly observed in the transparent groups (97.1%) collected from several production lots produced from different broodstock populations. A few normal individuals inherited the G/G genotype (5.0%), but the A/A and A/G genotypes were dominantly observed in the normal groups. The homologs region of the SNP was searched using a medaka genome database, and intron 12 of the Nell2a gene (located on chromosome 6 of the medaka genome) was highly matched. We also mapped the red sea bream Nell2a gene on the previously developed linkage maps, and this gene was mapped on a male linkage group, LG4-M. The newly found SNP was useful in eliminating broodstock possessing the causative gene of the body color transparency observed in juvenile stage of red sea bream. PMID- 29572775 TI - Development and Application of Liquid Biopsies in Metastatic Prostate Cancer. AB - PURPOSE OF REVIEW: Metastatic prostate cancer is a lethal and highly heterogeneous malignancy, associated with a broad spectrum of potentially actionable molecular alterations. In the past decade, disease profiling has expanded to include not only traditional tumor tissue, but also liquid biopsies of cells and genetic material circulating in the blood. These liquid biopsies offer a minimally invasive, repeatable source of tumor material for longitudinal disease profiling but also raise new technical and biological challenges. Here we will summarize recent advances in liquid biopsy strategies and the role they have played in biomarker development and disease management. RECENT FINDINGS: Technologies for analysis of circulating tumor cells (CTCs) continue to evolve rapidly, and the latest high content scanning platforms have underscored the phenotypic heterogeneity of CTC populations. Among liquid biopsies, CTC enumeration remains the most extensively validated prognostic marker to date, but other clinically relevant phenotypes like androgen receptor (AR) localization or presence of AR-V7 splice variant are important new predictors of therapy response. Serial genomic profiling of CTCs or circulating tumor DNA (ctDNA) is helping to define primary and acquired resistance mechanisms and helping to guide patient selection for targeted therapies such as poly(adenosine diphosphate [ADP] ribose) polymerase (PARP) inhibition. The era of liquid biopsy-based biomarkers has arrived, driven by powerful new enrichment and analysis techniques. As new blood-based markers are identified, their biological significance as disease drivers must be elucidated to advance new therapeutic strategies, and their clinical impact must be translated through assay standardization, followed by analytical and clinical validation. These efforts, already ongoing on multiple fronts, constitute the critical steps toward more effective precision management of advanced prostate cancer. PMID- 29572776 TI - Exome sequencing confirms molecular diagnoses in 38 Chinese families with hereditary spherocytosis. AB - Hereditary spherocytosis (HS), the most common cause of congenital hemolytic anemia, is caused by deficiency of the erythrocyte membrane proteins. Five causative genes (ANK1, SPTB, SPTA1, SLC4A1, and EPB42) have been identified. To date, molecular genetic studies have been performed in different populations, including the American, European, Brazilian, Japanese and Korean populations, whereas only a few studies have been described in the Chinese population. Here, by reanalysis of the exome data, we revealed causative mutations and established a definitive diagnosis of HS in all 38 Chinese families. We found 34 novel mutations and four reported mutations in three known HS-causing genes-17 in ANK1, 17 in SPTB and four in SLC4A1, suggesting that ANK1 and SPTB are the major genes in Chinese patients with HS. All of the ANK1 or SPTB mutations, scattered throughout the entire genes, are non-recurrent; and most of them are null mutations, which might cause HS via a haploinsufficiency mechanism. De novo mutations in ANK1 or SPTB often occur with an unexpected high frequency (87.5% and 64.2%, respectively). Our study updates our knowledge about the genetic profile of HS in Chinese and shows that family-based, especially parent-offspring trio, sequencing analysis can help to increase the diagnostic power and improve diagnostic efficiency. PMID- 29572777 TI - Synthesis and evaluation of a paclitaxel-binding polymeric micelle for efficient breast cancer therapy. AB - Paclitaxel (PTX) is one of the most effective anticancer drugs for the treatment of various solid tumors, but its clinical use is limited by its poor solubility, low bioavailability, and severe systemic toxicity. Encapsulation of PTX in polymeric nanoparticles is used to overcome these problems but these micelles still need improvements in stability, pharmacokinetics, therapeutic efficacy, and safety profiles. In this study, we demonstrate a facile fabrication of a stable PTX-binding micelle made from poly (ethylene glycol)-block-dendritic polylysine, whose primary amines were reacted with phenethyl isothiocyanate (PEITC), a hydrophobic anticancer agent under clinical study. The amphiphilic conjugate (PEG Gx-PEITC; Gx, the generation of the polylysine dendron) formed well-defined micelles whose core was composed of phenyl groups and thiourea groups binding PTX via pi-pi stacking and hydrogen bonding. Compared with the PTX-loaded poly(ethylene glycol)-block-poly(D,L-lactide) (PEGPDLLA/ PTX) micelles in clinical use, PTX-loaded PEG-Gx-PEITC third-generation (PEG-G3-PEITC/PTX) micelles showed slowed blood clearance, enhanced tumor accumulation, and thus much improved in vivo therapeutic efficacy in both subcutaneous and orthotopic human breast cancer xenografts. Therefore, PEG-G3-PEITC is a promising drug delivery system for PTX in the treatment of breast cancer. PMID- 29572778 TI - The Intersection of Emotional and Sociocognitive Competencies with Civic Engagement in Middle Childhood and Adolescence. AB - Civic developmental theory anticipates connections between normative developmental competencies and civic engagement, but little previous research has directly studied such links. The current study sought to contribute to civic development theory by examining associations between emotional and sociocognitive competencies (empathy, emotion regulation, prosocial moral reasoning, future orientation) and civic engagement (volunteering, informal helping, political behaviors and beliefs, environmental behaviors, social responsibility values, civic skills). Data came from a geographically and racially diverse sample of 2467 youth (Mage = 13.4, Range: 8-20 years, 56% female). The results indicated that empathy and future-orientation significantly predicted nearly all forms of civic engagement, whereas emotion regulation and prosocial moral reasoning were uniquely associated with specific forms of civic engagement. Exploratory multi group models indicated that empathy and emotion regulation were more strongly associated with civic engagement among younger youth and prosocial moral reasoning and future-orientation were more strongly related to civic engagement among older youth. The findings help to advance developmental theory of youth civic engagement. PMID- 29572779 TI - How Social and Mass Media Relate to Youth's Self-Sexualization: Taking a Cross National Perspective on Rewarded Appearance Ideals. AB - Although media exposure has been related to cognitive preoccupation with appearance, research rarely investigated adolescents' behavioral self sexualization. To address this gap, the present study among 12- to 16-year-olds (N = 1527; 50.2% girls) in Austria, Belgium, Spain, and South-Korea (1) investigates whether different types of media use relate to self-sexualization, (2) explores the explanatory value of rewarded appearance ideals, and (3) considers culture and gender as moderating factors. Despite cultural variation, a general trend of increasing self-sexualization with social media use and magazine reading appeared across the countries. Moreover, women's magazine reading and rewards were related to self-sexualization among all the girls across the countries, which suggests that girls may be more vulnerable to the examined effects. Overall, this study provides a better understanding of the unique contribution of specific media genres to youth's self-sexualization and points at the importance of social media use in girls' and boys' engagement in sexualizing appearance behaviors across four countries. PMID- 29572780 TI - Mathematical modeling of cancer-immune system, considering the role of antibodies. AB - A mathematical model for the quantitative analysis of cancer-immune interaction, considering the role of antibodies has been proposed in this paper. The model is based on the clinical evidence, which states that antibodies can directly kill cancerous cells (Ivano et al. in J Clin Investig 119(8):2143-2159, 2009). The existence of transcritical bifurcation, which has been proved using Sotomayor theorem, provides strong biological implications. Through numerical simulations, it has been illustrated that under certain therapy (like monoclonal antibody therapy), which is capable of altering the parameters of the system, cancer-free state can be obtained. PMID- 29572782 TI - A phase I/II trial of pemetrexed plus radiotherapy in elderly patients with locally advanced non-small cell lung cancer. AB - Background Radiotherapy (RT) is an effective treatment for elderly patients with locally advanced non-small-cell lung cancer (NSCLC); however, no clinical trials have investigated combination RT with pemetrexed (PEM) in chemotherapy-naive patients >=71 years old. We conducted a phase I/II study to evaluate the appropriate PEM dose, efficacy, and safety of PEM plus RT in elderly patients. Methods Patients >=71 years with performance status (PS) scores of 0-2 who had pathologically confirmed stage IIIA/IIIB NSCLC received PEM (500 mg/m2 on day 1 of a 28-day cycle, 4 courses) and RT (a single 2 Gy daily fraction on 5 consecutive days weekly from day 1; 60 Gy total). The primary endpoint was the objective response rate (ORR); the secondary endpoints were progression-free survival (PFS), overall survival (OS), and adverse events (AEs). Results Forty one patients with a median age of 79 years were enrolled; 31 were men. Eighteen patients had squamous cell carcinoma, 27 had stage IIIA disease, and 38 had PS scores 0-1. The ORR was 80.5%, while the median OS and PFS rates were 24.9 and 6.9 months, respectively. Two treatment-related deaths occurred owing to RT related pneumonitis and severe infection, respectively. Common hematological AEs were leucopenia and neutropenia; common non-hematological AEs were anorexia and constipation. Three patients developed PEM-induced interstitial lung disease; however, most AEs were RT-related. Conclusions Combination PEM and RT shows promising efficacy but relatively severe RT-related toxicities. Therefore, this treatment should be prescribed to elderly patients with caution.

AB - The nuclear transport factor 2 (NTF2) like superfamily includes members of the NTF2 family, delta-5-3-ketosteroid isomerases, and the beta subunit of ring hydroxygenases. This family plays important roles in both eukaryotic and prokaryotic cells, and is taken as a classic example of divergent evolution because proteins in this family exhibit diverse biological functions, although share common structural features. We cloned the gene RHE_RS02845 encoding a predicted NTF2-like domain-containing protein in Rhizobium etli, and prepared U 13C/15N-labeled protein samples for its three-dimensional NMR structural determination. Here, chemical shift assignments for both backbone and side-chain atoms are reported, which is prerequisite for further structural calculation and functional research using NMR spectroscopy. PMID- 29572783 TI - Post-progression survival following second-line chemotherapy in patients with advanced pancreatic cancer previously treated with gemcitabine: a meta-analysis. AB - Background Post-progression survival (PPS) could be a confounding element in interpreting data from clinical trials of second-line chemotherapy in patients with advanced pancreatic cancer (PC) previously treated with gemcitabine (GEM) because a recent meta-analysis of oxaliplatin combination therapy showed statistical heterogeneity for overall survival (OS) but not for progression-free survival (PFS). This study aimed to improve the understanding of the impact of PPS on OS in this setting. Methods Databases were searched to identify randomized controlled trials (RCTs) in the salvage setting. We evaluated relationships between OS and PFS, PPS, and other variables. Results Totally, 17 RCTs with 3253 patients were identified. Median OS was strongly and moderately associated with median PPS and PFS, respectively (r = 0.913; p < 0.001 and 0.780; p < 0.001, respectively). The proportion of patients with good performance status was significantly associated with both PPS and PFS (r = 0.574, p < 0.001 and 0.492, p < 0.001, respectively). The induction rate of subsequent chemotherapy was related to the duration of PPS and OS (r = 0.640, p < 0.001 and 0.647, p < 0.001, respectively). Median PPS and OS were significantly longer in recent trials than those in older trials (3.55 versus 2.78 months, p < 0.001 and 6.29 versus 5.02 months, p < 0.001). Conclusions Median PPS was strongly correlated with median OS. Given the recently increased opportunity for subsequent chemotherapy and supportive care, PPS may serve as an important element to clarify problems in this setting. PMID- 29572785 TI - Partial solid-state NMR 1H, 13C, 15N resonance assignments of a perdeuterated back-exchanged seven-transmembrane helical protein Anabaena Sensory Rhodopsin. AB - Anabaena Sensory Rhodopsin (ASR) is a unique photochromic membrane-embedded photosensor which interacts with soluble transducer and is likely involved in a light-dependent gene regulation in the cyanobacterium Anabaena sp. PCC 7120. We report partial spectroscopic 1H, 13C and 15N assignments of perdeuterated and back-exchanged ASR reconstituted in lipids. The reported assignments are in general agreement with previously determined assignments of carbon and nitrogen resonances in fully protonated samples. Because the back-exchange was performed on ASR in a detergent-solubilized state, the location of detected residues reports on the solvent accessibility of ASR in detergent. A comparison with the results of previously published hydrogen/exchange data collected on the ASR reconstituted in lipids, suggests that the protein has larger solvent accessible surface in the detergent-solubilized state. PMID- 29572781 TI - Noradrenergic Modulation on Dopaminergic Neurons. AB - It is now well accepted that there is a close relationship between noradrenergic and dopaminergic neurons in the brain, especially referring to the modulation of the locus coeruleus-norepinephrine (LC-NE) system on dopamine transmission. The disturbance of this modulation may contribute to neurodegeneration of dopaminergic neurons in Parkinson's disease. In this article, we briefly review evidence related to such modulation. Firstly, we illustrated the noradrenergic innervation and functional implication for the LC-NE system and nigra-striatum dopaminergic system. Furthermore, we depicted neuroprotective effects of the LC NE on dopaminergic neurons in vivo and in vitro. Moreover, we present data implicating the potential mechanisms underlying the modulation of the LC-NE system on dopaminergic neurons, in particular the effects of NE as a neurotrophic factor and through its ability to stimulate the expression of other neurotrophic factors, such as the brain-derived neurotrophic factor. Finally, we discussed other mechanisms intrinsic to NE's effects. A better understanding of the noradrenergic modulation on dopaminergic neurons may be rewarding by significant advances in etiologic study and promising treatment of Parkinson's disease. PMID- 29572787 TI - Reasoning from an incompatibility: False dilemma fallacies and content effects. AB - In the present studies, we investigated inferences from an incompatibility statement. Starting with two propositions that cannot be true at the same time, these inferences consist of deducing the falsity of one from the truth of the other or deducing the truth of one from the falsity of the other. Inferences of this latter form are relevant to human reasoning since they are the formal equivalent of a discourse manipulation called the false dilemma fallacy, often used in politics and advertising in order to force a choice between two selected options. Based on research on content-related variability in conditional reasoning, we predicted that content would have an impact on how reasoners treat incompatibility inferences. Like conditional inferences, they present two invalid forms for which the logical response is one of uncertainty. We predicted that participants would endorse a smaller proportion of the invalid incompatibility inferences when more counterexamples are available. In Study 1, we found the predicted pattern using causal premises translated into incompatibility statements with many and few counterexamples. In Study 2A, we replicated the content effects found in Study 1, but with premises for which the incompatibility statement is a non-causal relation between classes. These results suggest that the tendency to fall into the false dilemma fallacy is modulated by the background knowledge of the reasoner. They also provide additional evidence on the link between semantic information retrieval and deduction. PMID- 29572786 TI - Changes in hemoglobin profile reflect autologous blood transfusion misuse in sports. AB - The changes in hemoglobin (Hb) profile following autologous blood transfusion (ABT) for the first time were studied for anti-doping purposes. Twenty-four healthy, trained male subjects (aged 18-40) were enrolled and randomized into either the transfusion (T) or control (C) groups. Blood samples were taken from the T subjects at baseline, after withdrawal and reinfusion of 450 ml of refrigerated or cryopreserved blood, and from C subjects at the same time points. Hematological variables (Complete blood count, Reticulocytes, Immature Reticulocytes Fraction, Red-cell Distribution Width, OFF-hr score) were measured. The Hb types were analyzed by high-performance liquid chromatography and the Hemoglobin Profile Index (HbPI) arbitrarily calculated. Between-group differences were observed for red blood cells and reticulocytes. Unlike C, the T group, after withdrawal and reinfusion, showed a significant trend analysis for both hematological variables (Hemoglobin concentration, reticulocytes, OFF-hr score) and Hb types (glycated hemoglobin-HbA1c, HbPI). The control charts highlighted samples with abnormal values (> 3-SD above/below the population mean) after reinfusion for hematological variables in one subject versus five subjects for HbA1c and HbPI. A significant ROC-curve analysis (area = 0.649, p = 0.015) identified a HbA1c cut-off value <= 2.7% associated to 100% specificity of blood reinfusion (sensitivity 25%). Hemoglobin profile changed in trained subjects after ABT, with abnormal values of HbA1c and HbPI in 42% of subjects after reinfusion. Future studies will confirm the usefulness of these biomarkers in the anti-doping field. PMID- 29572789 TI - 3D Sponge-Matrix Histoculture: An Overview. AB - Three-dimensional cell culture and tissue culture (histoculture) is much more in vivo-like than 2D culture on plastic. Three-dimensional culture allows investigation of crucial events in tumor biology such as drug response, proliferation and cell cycle progression, cancer cell migration, invasion, metastasis, immune response, and antigen expression that mimic in vivo conditions. Three-dimensional sponge-matrix histoculture maintains the in vivo phenotype, including the formation of differentiated structures of normal and malignant tissues, perhaps due to cells maintaining their natural shape in a sponge-gel matrix such as Gelfoam(r). Sponge-matrix histoculture can also support normal tissues and their function including antibody-producing lymphoid tissue that allows efficient HIV infection, hair-growing skin, excised hair follicles that grow hair, pluripotent stem cells that form nerves, and much more. PMID- 29572790 TI - In Vivo-Like Growth Patterns of Multiple Types of Tumors in Gelfoam(r) Histoculture. AB - Diverse human tumors obtained directly from surgery or biopsy can grow at high frequency in 3-dimensional Gelfoam(r) histoculture for long periods of time and still maintain many of their in vivo properties. The in vivo properties maintained in vitro include 3-dimensional growth; maintenance of tissue organization and structure, such as changes associated with oncogenic transformation; retention of differentiated function; tumorigenicity; and growth of multiple types of cells from a single tumor. PMID- 29572791 TI - Expression and Targeting of Tumor Markers in Gelfoam(r) Histoculture: Potential Individualized Assays for Immuno-Oncology. AB - Tumor-specific antigens are important in the study of tumor biology, tumor diagnosis, and prognosis and as targets for tumor therapy. This chapter reviews patient colon, breast, and ovarian tumors in 3-dimensional Gelfoam(r) histoculture maintaining in vivo-like expression of the important tumor antigens, for example TAG-72 and CEA. We have also reviewed that fluorescent antibodies can target tumors in Gelfoam(r) histoculture, thereby providing an assay for individual patients for sensitivity to therapeutic antibodies which have become so important in immuno-oncology and other cancer therapies. PMID- 29572792 TI - Development of the Histoculture Drug Response Assay (HDRA). AB - The histoculture drug response assay (HDRA) was developed using Gelfoam(r) histoculture of all tumor types. Twenty tumor classes, including all the major ones, have been histocultured on Gelfoam(r) and tested for drug response. Quantitative and qualitative results show increasing cell kill with rising cytotoxic drug concentration, differential drug sensitivities of multiple cell types within individual cultured tumors, differential sensitivities to a single drug of a series of tumors of the same histopathological classification, differential sensitivities of individual tumors to a series of drugs, and sensitivity patterns of various tumor types similar to the sensitivities found in vivo. Therefore, the results indicated that precise therapeutic data can be obtained from tumor specimens growing in Gelfoam(r) histoculture in vitro for the individual cancer patient as well as for rational and relevant screening for novel agents active against human solid tumors. PMID- 29572793 TI - Diagnosis and Pathological Analysis of Patient Cancers by Detection of Proliferating Cells in Gelfoam(r) Histoculture. AB - Patient tumors grew in Gelfoam(r) histoculture with maintenance of tissue architecture, tumor-stromal interaction, and differentiated functions. In this chapter, we review the use of Gelfoam(r) histoculture to demonstrate proliferation indices of major solid cancer types explanted directly from surgery. Cell proliferation was visualized by histological autoradiography within the cultured tissues after [3H]thymidine incorporation by the proliferating cells. Epilumination polarization microscopy enables high-resolution imaging of the autoradiography of each cell. The histological status of the cultured tissues can be assessed simultaneously with the proliferation status. Carcinomas were observed to have areas of high epithelial proliferation with quiescent stromal cells. Sarcomas have high proliferation of the cancer cells of mesenchymal organ. Normal tissues can also proliferate at high rates. Mean growth fraction index (GFI) was highest for patient tumors with the pure subtype of small-cell lung cancer than other types of lung cancer. PMID- 29572794 TI - Clinical Correlation of the Histoculture Drug Response Assay in Gastrointestinal Cancer. AB - The histoculture drug response assay (HDRA) with tumors histocultured on Gelfoam(r) was tested for clinical correlation for advanced gastric and colorectal cancer patients. In one study, 29 patients were treated with drugs shown to be ineffective in the HDRA, and all 29 cases showed clinical chemoresistance. In nine patients treated with drugs shown to be effective in the HDRA, six showed clinical chemoresponse and three showed arrest of disease progression. In a study of 32 patients with stage III and IV gastric cancer treated with mitomycin C and 5-fluorouracil (5-FU), the survival rate of 10 patients whose tumors were sensitive to either mitomycin C and/or 5-fluorouracil in the HDRA was significantly better than that of 22 patients whose tumors were insensitive to both drugs in the HDRA. Twenty-nine patients with stage III and IV colorectal cancer without remaining measurable tumor lesions after surgery were treated with fluoropyrimidines adjuvantly. The recurrence-free survival rate of 7 patients whose tumors were sensitive to 5-fluorouracil in the HDRA was significantly better than that of 22 patients whose tumors were insensitive in the HDRA. In a companion study of 128 gastric cancer patients whose tumors were evaluated in the HDRA, the overall and disease-free survival rates of the HDRA sensitive group were found to be significantly higher than those of the HDRA resistant group, treated with the same drugs. PMID- 29572795 TI - Prospective Clinical Correlation of the Histoculture Drug Response Assay for Ovarian Cancer. AB - The histoculture drug response assay (HDRA) has been correlated clinically to a number of cancer types (please see Chaps. 7 - 11 of the present volume). The present chapter reviews the clinical trials of the HDRA for ovarian cancer. A prospective clinical trial of the HDRA for advanced epithelial ovarian cancer (AEOC) was performed at Asan Medical Center, Seoul, Korea. The clinical trial compared the efficacy of first-line therapy paclitaxel and carboplatinum in the HDRA and the clinical response for the patients whose tumors were tested in the HDRA. A series of patients (104) were treated with adjuvant combination chemotherapy of paclitaxel and carboplatinum after primary cytoreductive surgery. Tumor fragments were cultured on Gelfoam(r) and tested with paclitaxel and carboplatinum and evaluated with the MTT endpoint. Patients were categorized into two groups as either sensitive to both drugs (SS) or not sensitive to one or both drugs (R) based on HDRA results. The recurrence rate was much lower in the SS group compared to the R group, 29.2% vs. 69.8%, respectively. The SS group had a significantly longer progression-free survival compared to the R group, 34.0 months vs. 16.0 months, respectively. In another clinical trial, the HDRA was performed on 85 cases of ovarian cancer and 97% were evaluable. HDRA results were correlated to clinical response of 15 patients who received cisplatinum-based therapy that included doxorubicin and cyclophosphamide (CAP therapy). The true positive rate was 88%, the true-negative rate was 86%, the sensitivity was 88%, the specificity was 86%, and the accurate prediction rate was 87% when HDRA results were compared to the response of the treated patients. PMID- 29572796 TI - Clinical Correlation of the Histoculture Drug Response Assay for Head and Neck Cancer. AB - Gelfoam(r) histoculture was utilized to develop the histoculture drug response assay (HDRA) for head and neck cancer. Specimens of head and neck tumors were evaluated for sensitivity to the following drugs: cisplatinum (CDDP), 5 fluorouracil (5-FU), and the combination of CDDP and 5-FU. In the first clinical study at UCSD, 10 of 12 patients with tumors that were drug sensitive in Gelfoam(r) histoculture had either complete or partial response clinically. Comparisons of HDRA results, obtained with [3H]thymidine incorporation as the endpoint were made with clinical responses, i.e., complete response, partial response, or no response. The overall accuracy of the HDRA was 74% in this correlative clinical trial; the predictive positive value was 83%, the sensitivity was 71%, and the specificity was 78%. Seven of 11 patients with HDRA resistant tumors demonstrated no response for a predictive negative value of 64%. In a subsequent study at Memorial Sloan Kettering Cancer Center, tumor specimens from 41 to 42 patients undergoing treatment for head and neck cancer were successfully evaluated by the HDRA. The histocultured tumors were treated with 5 FU and/or CDDP and a control group received no drug treatment. After completion of drug treatment, the relative cell survival in the tumors was determined using the MTT endpoint. Sensitivity was defined as a tumor inhibition rate (IR) of greater than 30%. Survival comparisons were performed using the generalized Wilcoxon test for the comparison of Kaplan-Meier survival curves. Resistance to 5 FU was observed in 13 cases (32%), to CDDP in 13 cases (32%), and to both agents in 11 cases (27%). The 2-year cause-specific survival was significantly greater for patients sensitive to 5-FU than patients who were resistant (85% vs. 64%), CDDP (86% vs. 64%), or both agents (85% vs. 63%). These results demonstrate the clinical usefulness of the HDRA for head and neck cancer. PMID- 29572797 TI - Clinical Usefulness of the Histoculture Drug Response Assay for Breast Cancer. AB - The histoculture drug response assay (HDRA) was used to compare drug sensitivity of recurrent and primary breast cancer in vitro as well as in the clinic. The HDRA utilizes 3-dimensional culture of human tumors on Gelfoam(r). The evaluation rate was 98.8%. The HDRA mean inhibition rate of primary tumors vs. recurrent tumors was, respectively, 57.9% and 38.6% for doxorubicin (DOX); 59.9% and 42.8% for mitomycin C (MMC); 49.0% and 33.4% for 5-fluorouracil (5-FU); and 34.5% and 16.0% for cisplatinum (CDDP). The recurrent cases were pretreated clinically with CAF (cyclophosphamide [CTX], DOX, and 5-FU), CEF (CTX, epirubicin [EPN], and 5 FU), or CMF (CTX, methotrexate [MTX], and 5-FU). 64.7% of the recurrent cases were resistant to all four agents tested compared to 27% of the primary cases. Only 5.9% of the recurrent cases were sensitive to three or more agents as opposed to 18% of the primary cases. The correlation of the HDRA results to clinical outcome in another breast-cancer study was 80.0% with 15 cases evaluated consisting of five true positives, three false positives, seven true negatives, and no false negatives. HDRA was also performed on surgical specimens of primary tumor and axillary lymph node metastasis from each of 30 breast cancer patients. The lymph-node metastases were more resistant than the primary tumor for DOX, 5 FU, and MMC, but not for CDDP. The data suggest that both primary tumor and metastases from individual patients should be tested in the HDRA to enhance clinical efficacy of chemotherapy. There also was a lack of correlation with breast cancer subtype and drug response in the HDRA, further suggesting the importance of individualized treatment for breast cancer patients afforded by the HDRA. PMID- 29572798 TI - Clinical Usefulness of the Histoculture Drug Response Assay for Prostate Cancer and Benign Prostate Hypertrophy (BPH). AB - The histoculture drug response assay (HDRA) has been adapted to determine androgen sensitivity in Gelfoam histoculture of human benign prostatic tissue as well as prostate cancer. Gelfoam histoculture was used to measure androgen independent and androgen-dependent growth of benign and malignant prostate tissue. The androgen-sensitivity index was significantly higher in 23 paired specimens of prostate cancer compared to benign prostate hypertrophy (BPH). Genistein decreased the androgen-sensitivity index of BPH and prostate cancer in Gelfoam(r) histoculture in a dose-dependent manner. PMID- 29572799 TI - In Vivo-Like Cell-Cycle Phase Distribution of Cancer Cells in Gelfoam(r) Histoculture Observed in Real Time by FUCCI Imaging. AB - FUCCI color codes cells as they express different color fluorescent proteins as they go through phases of the cell cycle. The cell cycle phase distribution of cancer cells in Gelfoam(r) histoculture was similar to in vivo tumors, whereby only the surface cells proliferate and interior cells are quiescent in G0/G1. In contrast, in 2D cancer-cell culture, most of the cells are always cycling. The cancer cells responded similarly to toxic chemotherapy in Gelfoam(r) culture as in vivo; as such, therapy is cell cycle dependent. In 2D culture, cancer cells were much more chemosensitive. These results indicate why the drug response pattern of tumors in Gelfoam(r) histoculture reflects what is observed in vivo. PMID- 29572800 TI - Methionine Dependency Determination of Human Patient Tumors in Gelfoam(r) Histoculture. AB - The elevated requirement of methionine by cancer cells (methionine dependence) is a general metabolic abnormality in cancer. Methionine-dependent cancer cells are unable to proliferate and arrest in the late S/G2 phase of the cell cycle when methionine is restricted in vitro or in vivo. Cell-cycle arrest in late S/G2 was used as a biomarker of methionine dependence for patient tumors in Gelfoam(r) histoculture. Human cancer patient tumors, including tumors of the colon, breast, ovary, prostate, and a melanoma, were observed to be methionine dependent in Gelfoam(r) histoculture based on cell cycle analysis. This simple method can be used to screen patient tumors for methionine dependence and then subsequently apply appropriate chemotherapy for these patients to target this cancer-specific metabolic abnormality. PMID- 29572801 TI - Hair-Shaft Growth in Gelfoam(r) Histoculture of Skin and Isolated Hair Follicles. AB - Human scalp skin with abundant hair follicles in various stages of the hair growth cycle was histocultured for up to 40 days on Gelfoam(r) at the air/liquid interface. The anagen hair follicles within the histoculture scalp skin produced growing hair shafts. Hair follicles could continue their cycle in histoculture; for example, apparent spontaneous catagen induction was observed both histologically and by the actual regression of the hair follicle. In addition, vellus follicles were shown to be viable at day 40 after initiation of culture. Follicle keratinocytes continued to incorporate [3H]thymidine for up to several weeks after shaft elongation had ceased. Intensive hair growth was observed in the pieces of shaved mouse skin histocultured on Gelfoam(r). Isolated human and mouse hair follicles also produced growing hair shafts. By day 63 in histoculture of mouse hair follicles, the number of hair follicle-associated pluripotent (HAP) stem cells increased significantly and the follicles were intact. Gelfoam(r) histoculture of skin demonstrated that the hair follicle cells are the most sensitive to doxorubicin which prevented hair growth, thereby mimicking chemotherapy-induced alopecia in Gelfoam(r) histoculture. PMID- 29572802 TI - Hair Follicle-Associated Pluripotent (HAP) Stem Cells in Gelfoam(r) Histoculture for Use in Spinal Cord Repair. AB - The stem cell marker, nestin, is expressed in the hair follicle, both in cells in the bulge area (BA) and the dermal papilla (DP). Nestin-expressing hair follicle associated-pluripotent (HAP) stem cells of both the BA and DP have been previously shown to be able to form neurons, heart muscle cells, and other non follicle cell types. The ability of the nestin-expressing HAP stem cells from the BA and DP to repair spinal cord injury was compared. Nestin-expressing HAP stem cells from both the BA and DP grew very well on Gelfoam(r). The HAP stem cells attached to the Gelfoam(r) within 1 h. They grew along the grids of the Gelfoam(r) during the first 2 or 3 days. Later they spread into the Gelfoam(r). After transplantation of Gelfoam(r) cultures of nestin-expressing BA or DP HAP stem cells into the injured spinal cord (including the Gelfoam(r)) nestin expressing BA and DP cells were observed to be viable over 100 days post-surgery. Hematoxylin and eosin (H&E) staining showed connections between the transplanted cells and the host spine tissue. Immunohistochemistry showed many Tuj1-, Isl 1/2, and EN1-positive cells and nerve fibers in the transplanted area of the spinal cord after BA Gelfoam(r) or DP Gelfoam(r) cultures were transplanted to the spine. The spinal cord of mice was injured to effect hind-limb paralysis. Twenty eight days after transplantation with BA or DP HAP stem cells on Gelfoam(r) to the injured area of the spine, the mice recovered normal locomotion. PMID- 29572803 TI - Nerve Growth and Interaction in Gelfoam(r) Histoculture: A Nervous System Organoid. AB - Nestin-expressing hair follicle-associated pluripotent (HAP) stem cells reside mainly in the bulge area (BA) of the hair follicle but also in the dermal papilla (DP). The BA appears to be origin of HAP stem cells. Long-term Gelfoam(r) histoculture was established of whiskers isolated from transgenic mice, in which there is nestin-driven green fluorescent protein (ND-GFP). HAP stem cells trafficked from the BA toward the DP area and extensively grew out onto Gelfoam(r) forming nerve-like structures. These fibers express the neuron marker beta-III tubulin-positive fibers and consisted of ND-GFP-expressing cells and extended up to 500 mm from the whisker nerve stump in Gelfoam(r) histoculture. The growing fibers had growth cones on their tips expressing F-actin indicating that the fibers were growing axons. HAP stem cell proliferation resulted in elongation of the follicle nerve and interaction with other nerves in 3D Gelfoam(r) histoculture, including the sciatic nerve, trigeminal nerve, and trigeminal nerve ganglion. PMID- 29572804 TI - Histoculture and Infection with HIV of Functional Human Lymphoid Tissue on Gelfoam(r). AB - Gelfoam(r) histoculture provides a valuable tool for experimental studies of normal and pathological tissue physiology. It allows us to understand cell-cell interactions by mirroring their original spatial relationship within body tissues. Gelfoam(r) histoculture can be employed to model host-pathogen interactions mimicking in vivo conditions in vitro. In the present chapter, we describe a protocol to process and infect lymphoid tissue explants with HIV and maintain them in Gelfoam(r) histoculture at the liquid-air interface. The Gelfoam(r) histocultures with human immunodeficiency virus (HIV) type 1-infected tissues have been used to further understand the biology of early HIV-1 pathogenesis, as well as a novel ex vivo platform to test the efficacy and toxicity of antiviral drugs. PMID- 29572805 TI - Imaging DNA Repair After UV Irradiation Damage of Cancer Cells in Gelfoam(r) Histoculture. AB - DNA damage repair in response to UVC irradiation was imaged in cancer cells growing in Gelfoam(r) histoculture. UVC-induced DNA damage repair was imaged with green fluorescent protein (GFP) fused to the DNA damage response (DDR)-related binding protein 53BP1 in MiaPaCa-2 human pancreatic cancer cells. Three dimensional Gelfoam(r) histocultures and confocal imaging enabled 53BP1-GFP nuclear foci to be observed within 1 h after UVC irradiation, indicating the onset of DNA damage repair response. Induction of UV-induced 53BP1-GFP focus formation was limited up to a depth of 40 MUm in Gelfoam(r) histoculture of MiaPaCa-2 cells, indicating this was the depth limit of UVC irradiation. PMID- 29572806 TI - Comparison of "Dimensionality" of Cancer Cell Culture in Gelfoam(r) Histoculture and Matrigel. AB - Cell and tissue culture can be performed on different substrates such as on plastic, in MatrigelTM, and on Gelfoam(r), a sponge matrix. Each of these substrates consists of a very different surface, ranging from hard and inflexible, a gel, and a sponge-matrix, respectively. Folkman and Moscona found that cell shape was tightly coupled to proper gene expression. The flexibility of a substrate is important for cells to maintain their optimal shape. Human osteosarcoma cells, stably expressing a fusion protein of av integrin, and green fluorescent protein (GFP), grew as a simple monolayer without any structure formation on the surface of a plastic dish. When the osteosarcoma cells were cultured within Matrigel, the cancer cells formed colonies but no other structures. When the cancer cells were seeded on Gelfoam(r), the cells formed 3 dimensional tissue-like structures. These results indicate that Gelfoam(r) histoculture, unlike MatrigelTM culture, is true 3-dimensional. PMID- 29572807 TI - Imaging the Governing Step of Metastasis in Gelfoam(r) Histoculture. AB - Distant organ colonization by cancer cells is the governing step of metastasis. We review in this chapter the modeling and imaging of organ colonization by cancer cells in Gelfoam(r) histoculture. ANIP 973 lung cancer cells expressing green fluorescent protein (GFP) were injected intravenously into nude mice, whereby they formed brilliantly fluorescing metastatic colonies on the mouse lung. The seeded lung tissue was then excised and incubated in the three dimensional Gelfoam(r) histoculture that maintained the critical features of progressive in vivo organ colonization. Tumor progression was continuously visualized by GFP fluorescence of individual cultures over a 52-day period, during which tumor colonies spread throughout the lung. Organ colonization was selective in Gelfoam(r) histoculture for lung cancer cells to grow on lung tissue, since no growth occurred on histocultured mouse liver tissue. The ability to support selective organ colonization in Gelfoam(r) histoculture and visualize tumor progression by GFP fluorescence allows the in vitro study of the governing processes of metastasis. PMID- 29572808 TI - Readmission and complications within 30 days after intrathecal baclofen pump placement. AB - AIM: To describe 30-day outcomes after intrathecal baclofen (ITB) pump placement in children and identify risk factors for readmission, reoperation, and perioperative complication using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database. METHOD: Patients aged 0 to 18 years who underwent ITB pump placement (2012-2014) comprised the study cohort defined in the database. Multivariate regression analysis was performed using preoperative and perioperative data from the American College of Surgeons' NSQIP-P database. Outcomes of interest within 30 days of surgery were (1) unplanned reoperation; (2) unplanned readmission; and (3) composite postoperative event, including complication, reoperation, and/or readmission. RESULTS: We identified 423 surgeries; 246 (58.2%) patients were male, 177 (41.8%) patients were female. Median age was 12 years and 11 months. Median operative time was 70 minutes (interquartile range 56-97min). Mean length of stay was 3.8 days. The patient population had a high number of medical comorbidities. The overall readmission rate was 7.3%; mean postoperative admission date was 14.1 days after surgery. Of readmitted patients, 64.5% underwent reoperation. The most common indication for reoperation was surgical site infection. Female sex was associated with decreased risk of readmission (odds ratio [OR] 0.25, 95% confidence interval [CI] 0.09 0.65; p=0.01); American Society of Anesthesiologists Classification of greater than or equal to 3 was associated with decreased risk of unplanned return to surgery (OR 0.26, 95% CI 0.11-0.66; p=0.04); length of stay greater than or equal to 3 days at index surgery was associated with increased risk of composite 30-day perioperative event (OR 2.33, 95% CI 1.29-4.20; p=0.01). INTERPRETATION: Our data provide national perspectives on 30-day perioperative outcomes for ITB pump placement in children. Results illustrate NSQIP-P database collection methodology and highlight opportunities for quality improvement in clinical practice. WHAT THIS PAPER ADDS: Seven percent of patients who underwent intrathecal baclofen pump placement required readmission within 30 days. The most common indication for reoperation was surgical site infection. PMID- 29572809 TI - PLZF-expressing CD4 T cells show the characteristics of terminally differentiated effector memory CD4 T cells in humans. AB - We show the presence of lymphoid tissue-resident PLZF+ CD45RA+ RO+ CD4 T cells in humans. They express HLA-DR, granzyme B, and perforin and are low on CCR7 like terminally differentiated effector memory (Temra) cells and are likely generated from effector T cells (Te) or from central (Tcm) or effector (Tem) memory T (Tcm) cells during immune responses. Tn, Naive T cells. PMID- 29572810 TI - Chloroquine-treated dendritic cells require STAT1 signaling for their tolerogenic activity. AB - MS and EAE are T cell-driven autoimmune diseases of the CNS where IL-17-producing Th17 cells promote damage and are pathogenic. Conversely, tolerogenic DCs induce Treg cells and suppress Th17 cells. Chloroquine (CQ) suppresses EAE through the modulation of DCs by unknown mechanisms. Here, we show that STAT 1 is necessary for CQ-induced tolerogenic DCs (tolDCs) to efficiently suppress EAE. We observed that CQ induces phosphorylation of STAT1 in DCs in vivo and in vitro. Genetic blockage of STAT1 abrogated the suppressive activity of CQ-treated DCs. Opposed to its WT counterparts, CQ-treated STAT1-/- BMDCs were unable to suppress Th17 cells and increased EAE severity. Our findings show that STAT1 is a major signaling pathway in CQ-induced tolDCs and may shed light on new therapeutic avenues for the induction of tolDCs in autoimmune diseases such as MS. PMID- 29572811 TI - Teledermatologist expert skin advice: A unique model of care for managing skin disorders and adverse drug reactions in hepatitis C patients. AB - OBJECTIVES: To conduct an audit of teledermatologist expert skin advice, a store and forward tele-dermatological service, to determine its effectiveness and user satisfaction in managing cutaneous adverse drug reactions in patients with hepatitis C, and to demonstrate a unique collaborative model of care for patients receiving specialised drug therapy. METHODS: A retrospective analysis of data on teledermatologist expert skin advice referrals from January 2014 to December 2015 was performed. The primary outcomes assessed included number of referrals, referral locations, diagnoses, response times, quality of clinical information provided and user satisfaction ratings. RESULTS: Altogether 43 consultations from 29 referring sites were received from Australian metropolitan and rural settings. Of the patients, 43 were diagnosed with an adverse drug reaction related to the use of either telaprevir or simeprevir. The average time taken for the dermatologist to reply electronically with a final diagnosis and management plan was 1 h 57 min. As many as 26% of referrals required additional photos to establish a diagnosis due to poor-quality images or insufficient detail. Altogether 18 clinicians completed the customer satisfaction survey, all of whom rated teledermatologist expert skin advice nine or above on a scale of one to 10. CONCLUSIONS: Teledermatologist expert skin advice was regarded by clinicians as a valuable patient care service. The platform is a novel modality that supports patients undergoing specialised treatments at risk of cutaneous adverse drug reaction. PMID- 29572812 TI - The risk, burden, and management of non-communicable diseases in cerebral palsy: a scoping review. AB - AIM: To examine the risk, burden, and management of non-communicable diseases (NCDs) among people with cerebral palsy (CP). METHOD: Databases (Ovid MEDLINE, Embase Ovid, CINAHL Plus) were systematically searched up to August 2017. Data on the prevalence of risk factors for, and the burden and management of, cardiovascular diseases, diabetes, cancers, and respiratory diseases were extracted. RESULTS: Thirty-six studies that examined the prevalence of risk factors among people with CP were identified. There was inconsistent evidence that people with CP had higher prevalence of metabolic risk factors such as hypertension, hyperlipidaemia, and obesity, but strong evidence that they participated in low levels of physical activity, compared with people without CP. Seven studies reported on the burden of NCDs. Adults with CP had a higher risk of NCDs, including stroke, chronic obstructive pulmonary disease, and other heart conditions, and death due to NCDs, including cancers, chronic obstructive pulmonary disease, stroke, and ischaemic heart disease, compared with the general population. Only one study reported on the management of NCD, specifically the uptake of breast cancer screening among females. INTERPRETATION: The burden of NCDs is higher among adults with CP compared with the general population. Further research is required to determine the prevalence of metabolic risk factors and management of NCDs among people with CP. WHAT THIS PAPER ADDS: Adults with cerebral palsy (CP) have an increased risk of non-communicable diseases (NCDs) and increased risk of death because of NCDs. Evidence is inconsistent about the elevated prevalence of metabolic risk factors for NCDs. Evidence is consistent that people with CP participate in reduced physical activity. Only one study reported on management of NCD among people with CP. Available evidence suggests people with CP are less likely to receive preventive medicine. PMID- 29572813 TI - The validity of caries risk assessment in young adults with past caries experience using a screening Cariogram model without saliva tests. AB - OBJECTIVE: To evaluate the caries-predictive validity of a screening Cariogram model without saliva tests in Chinese young adults with past caries experience. METHODS: Two-hundred and fifteen Chinese young adults seeking dental care were included in this observational study, with informed consent obtained. All participants were 18-29 years of age and with past caries experience. A caries risk assessment was made at baseline using a full-blown Cariogram model and a screening Cariogram model without saliva tests; this assessment included bacterial count, saliva secretion and buffer capacity. Participants were divided into five risk groups according to 'the chance of avoiding caries' expressed in Cariogram software with two models. Each participant was required to receive re examination after 2 years and then the actual caries increment (DeltaDMFS) was calculated. The correlation between DeltaDMFS and the ratings of caries risk was analysed using Spearman rank correlation. Differences between the full-blown and screening models were expressed as area under the receiver-operating characteristics (ROC) curve (AUC). RESULTS: One-hundred and ninety-two participants finished the 2-year follow-up study, after 23 dropped out. The mean 2-year caries increment was 0.67 +/- 1.03. Both Cariogram models displayed a statistically significant relationship with caries development (P < 0.001): more new caries was found among those assessed with high risk compared with those assessed with low risk. No statistically significant difference of the AUC was found between the two Cariogram models (P > 0.05). CONCLUSIONS: The Cariogram model without saliva tests does not significantly decrease the caries-predictive ability in young adults with a history of caries. This screening model is a potential tool for rapid caries risk assessment for such populations. PMID- 29572814 TI - A Person-Centered Approach to Poststroke Care: The COMprehensive Post-Acute Stroke Services Model. AB - Many individuals who have had a stroke leave the hospital without postacute care services in place. Despite high risks of complications and readmission, there is no standard in the United States for postacute stroke care after discharge home. We describe the rationale and methods for the development of the COMprehensive Post-Acute Stroke Services (COMPASS) care model and the structure and quality metrics used for implementation. COMPASS, an innovative, comprehensive extension of the TRAnsition Coaching for Stroke (TRACS) program, is a clinician-led quality improvement model providing early supported discharge and transitional care for individuals who have had a stroke and have been discharged home. The effectiveness of the COMPASS model is being assessed in a cluster-randomized pragmatic trial in 41 sites across North Carolina, with a recruitment goal of 6,000 participants. The COMPASS model is evidence based, person centered, and stakeholder driven. It involves identification and education of eligible individuals in the hospital; telephone follow-up 2, 30, and 60 days after discharge; and a clinic visit within 14 days conducted by a nurse and advanced practice provider. Patient and caregiver self-reported assessments of functional and social determinants of health are captured during the clinic visit using a web-based application. Embedded algorithms immediately construct an individualized care plan. The COMPASS model's pragmatic design and quality metrics may support measurable best practices for postacute stroke care.

AB - Optimal molecular diagnosis of primary dyslipidemia is challenging to confirm the diagnosis, test and identify at risk relatives. The aim of this study was to test the application of a single targeted next-generation sequencing (NGS) panel for hypercholesterolemia, hypocholesterolemia, and hypertriglyceridemia molecular diagnosis. NGS workflow based on a custom AmpliSeq panel was designed for sequencing the most prevalent dyslipidemia-causing genes (ANGPTL3, APOA5, APOC2, APOB, GPIHBP1, LDLR, LMF1, LPL, PCSK9) on the Ion PGM Sequencer. One hundred and forty patients without molecular diagnosis were studied. In silico analyses were performed using the NextGENe software and homemade tools for detection of copy number variations (CNV). All mutations were confirmed using appropriate tools. Eighty seven variations and 4 CNV were identified, allowing a molecular diagnosis for 40/116 hypercholesterolemic patients, 5/13 hypocholesterolemic patients, and 2/11, hypertriglyceridemic patients respectively. This workflow allowed the detection of CNV contrary to our previous strategy. Some variations were found in previously unexplored regions providing an added value for genotype-phenotype correlation and familial screening. In conclusion, this new NGS process is an effective mutation detection method and allows better understanding of phenotype. Consequently this assay meets the medical need for individualized diagnosis of dyslipidemia.

AB - The Parkinson's disease-associated protein alpha-synuclein (alphaSN) is natively unfolded but its structure can be modulated by membranes and surfactants. The opportunistic pathogen Pseudomonas aeruginosa (PA) produces and secretes the biosurfactant rhamnolipid (RL) which modulates bacterial biofilm. Here, we show that monomeric RL enhances the ability of alphaSN to permeabilize membranes, while micellar RL rapidly induces protein beta-sheet structure with a worm-like fibrillary appearance, which cannot seed RL-free fibrillation but transforms into linear fibrils faster than alphaSN fibrillating on its own. Exposure to alphaSN reduces the degree of biofilm formation by PA unless RL is present. Our data suggest that RL interactions with alphaSN may affect both alphaSN aggregation and cell toxicity, potentially implicating microbiomic metabolites in the origin and propagation of Parkinson's disease.

Use of multiple, complementary tetramers with different fluorochromes enhances sensitivity and specificity allowing naive antigen-specific B cells to be readily distinguished within a polyclonal repertoire. Activated, affinity-matured B cells, however, can be detected effectively using a single tetramer.

PMID- 29572819 TI - Two distinct glyceraldehyde-3-phosphate dehydrogenases in glycolysis and gluconeogenesis in the archaeon Haloferax volcanii. AB - The halophilic archaeon Haloferax volcanii degrades glucose via the semiphosphorylative Entner-Doudoroff pathway and can also grow on gluconeogenic substrates. Here, the enzymes catalysing the conversion of glyceraldehyde-3 phosphate (GAP) to 3-phosphoglycerate were analysed. The genome contains the genes gapI and gapII encoding two putative GAP dehydrogenases, and pgk encoding phosphoglycerate kinase (PGK). We show that gapI is functionally involved in sugar catabolism, whereas gapII is involved in gluconeogenesis. For pgk, an amphibolic function is indicated. This is the first report of the functional involvement of a phosphorylating glyceraldehyde-3-phosphate dehydrogenase and PGK in sugar catabolism in archaea. Phylogenetic analyses indicate that the catabolic gapI from H. volcanii is acquired from bacteria via lateral genetransfer, whereas the anabolic gapII as well as pgk are of archaeal origin. PMID- 29572820 TI - Semantic and Phonemic Verbal Fluency Discrepancy in Mild Cognitive Impairment: Potential Predictor of Progression to Alzheimer's Disease. AB - OBJECTIVES: To assess the utility of verbal fluency discrepancy scores in predicting progression to Alzheimer's disease (AD) in a cohort of individuals with mild cognitive impairment (MCI). DESIGN: Case control. SETTING: Cases identified from new referrals to a memory clinic and controls identified from The Irish Longitudinal Study on Ageing. PARTICIPANTS: Of 308 individuals with MCI at baseline identified from consecutive referrals to a memory clinic and compared at with age-, sex-, and education-matched controls (n=302), 161 completed 2 years of follow-up or progressed to AD during the study period. MEASUREMENTS: Verbal fluency discrepancy (semantic-phonemic fluency) scores at baseline were calculated for each participant. Each case was followed with repeated neuropsychological measurements, and multidisciplinary consensus diagnosis was recorded. RESULTS: Mean discrepancy score for those who progressed to AD (2.7) was significantly lower than for those who retained a MCI diagnosis (4.8) and normal controls (7.7) (p<.001). Logistic regression revealed that, for each unit decrease in discrepancy score at baseline, the odds of progressing to AD were 9% greater. (Exp(B) = 1.09, p=.02) CONCLUSION: Individuals with MCI have less of a semantic advantage than those without MCI. Those with MCI presenting with a phonemic advantage at initial assessment warrant close follow-up and a high index of suspicion for progression to AD. PMID- 29572821 TI - Perioperative neonatal brain injury is associated with worse school-age neurodevelopment in children with critical congenital heart disease. AB - AIM: To assess the impact of perioperative neonatal brain injury and brain volumes on neurodevelopment throughout school-age children with critical congenital heart disease (CHD). METHOD: Thirty-four survivors of neonatal cardiac surgery (seven females, 27 males) were included. Neonatal preoperative and postoperative cerebral magnetic resonance imaging was performed and neurodevelopment was assessed at 24 months (SD 0.7, n=32, using Bayley Score of Infant and Toddler Development, Child Behavior Checklist) and 6 years (mean age 5y 11mo; SD 0.3, n=30, using Movement Assessment Battery for Children, Wechsler Preschool and Primary Scale of Intelligence, Child Behavior Checklist, Teacher Report Form). Brain injury, brain volumes, and cortical measures were related to outcome with adjustment for maternal educational level. RESULTS: Two-year cognitive score and 6-year Full-scale IQ were poorer in children with neonatal white matter injury (n=21, all p<0.05), with higher teacher-reported attention problems (p=0.03). Five of six children with involvement of the posterior limb of the internal capsule showed motor problems (p=0.03). Children with a below average Fulll-scale IQ (<85, n=9) showed smaller volumes of basal ganglia thalami (-8%, p=0.03) and brain stem (-7%, p=0.03). INTERPRETATION: Our findings provide evidence of unfavourable outcome in school-age children with critical CHD who acquire perioperative neonatal brain injury. WHAT THIS PAPER ADDS: This paper extends knowledge about neonatal brain injury and long-term outcome in congenital heart disease. Children with white matter injury show lower IQ and more attention problems at school age. Injury of the posterior limb of the internal capsule increases the risk of motor problems. This study provides evidence for worse outcomes in neonates acquiring brain injury around cardiac surgery. PMID- 29572822 TI - Methotrexate restores the function of peripheral blood regulatory T cells in psoriasis vulgaris via the CD73/AMPK/mTOR pathway. AB - BACKGROUND: Methotrexate (MTX) is used to treat psoriasis, a chronic inflammatory skin disease. OBJECTIVES: To investigate the molecular mechanism of MTX in the treatment of psoriasis. METHODS: Regulatory T cells (Tregs) and effector T (Teff) cells were isolated from the blood of patients with psoriasis and healthy controls. The proliferation of Teff cells was detected by carboxyfluorescein succinimidyl ester assay. The interferon (IFN)-gamma and interleukin (IL)-17 levels were analysed by enzyme-linked immunosorbent assay. The expression of CD73 and FoxP3 were determined by flow cytometry. The expression of proteins in the AMPK/mTOR pathway were detected by Western blot analysis. RESULTS: The data suggested that patients with psoriasis have Tregs with decreased immune suppression function and reduced expression of CD73 compared with healthy controls. Moreover, MTX could significantly restore the immunosuppressive function of IL-17-secreting Tregs. This, in turn, inhibits aberrant proliferation of Teff cells in patients with psoriasis, reverses downregulation of CD73, upregulates phosphorylated AMPK and inhibits phosphorylated mTOR, and downregulates IL-17 and IFN-gamma levels. CONCLUSIONS: We speculate that MTX can restore the immunosuppressive function of Tregs through upregulating CD73, activating AMPK and inactivating the mTOR pathway. These findings may partly explain the mechanism by which MTX treats psoriasis. PMID- 29572823 TI - A systematic review and meta-analysis of velamentous cord insertion among singleton pregnancies and the risk of preterm delivery. AB - BACKGROUND: Observational studies have reported varying results about the association of velamentous cord insertion (VCI) with adverse pregnancy outcomes. OBJECTIVES: To evaluate the risk of preterm delivery among singleton pregnancies complicated by VCI. SEARCH STRATEGY: Various databases were searched for English language articles published up to February, 28, 2017, using keywords including VCI; abnormal placentation; abnormal cord insertions; adverse perinatal outcomes; and preterm birth. Outcome measures included preterm delivery; pre-eclampsia; cesarean delivery; fetal demise in utero (FDIU); and small for gestational age (SGA). SELECTION CRITERIA: Only studies involving VCI were included in the meta analysis. DATA COLLECTION AND ANALYSIS: Analyses were performed using RevMan version 5.3.5 (The Nordic Cochrane Centre, Copenhagen, Denmark). MAIN RESULTS: There were six studies included in the analysis. The VCI and control groups comprised 16 295 and 1 366 485 women, respectively. An increased incidence of preterm delivery was found for the VCI group compared with the control group (11.8% vs 7.0%; adjusted odds ratio [aOR] 1.95, 95% confidence interval [CI] 1.85 2.04). A diagnosis of VCI was also associated with cesarean delivery (aOR 1.17, 95% CI 1.12-1.23), SGA (aOR 1.93, 95% CI 1.83-2.04), and FDIU (aOR 3.96, 95% CI 3.21-4.89). CONCLUSION: The presence of VCI was associated with adverse pregnancy outcomes.

PMID- 29572825 TI - New onset non-alcoholic fatty liver disease after resection of pancreatic neuroendocrine tumors. AB - BACKGROUND AND OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) and non alcoholic steatohepatis (NASH) may occur after pancreatic resection due to exocrine pancreatic insufficiency (EPI). Patients with long-term survival, such as after pancreatic neuroendocrine tumor (pNET) resection, are at risk of NAFLD/NASH. We aimed to determine the incidence and risk factors for new onset NAFLD/NASH and EPI after pNET resection. METHODS: Retrospective monocenter cohort study. Patients who underwent pNET resection (1992-2016) were assessed for new onset NAFLD/NASH and EPI. Postoperative NAFLD/NASH was determined by a blinded abdominal radiologist, who compared pre- and postoperative imaging. RESULTS: Out of 235 patients with pNET, a total of 112 patients underwent resection and were included with a median follow-up of 54 months. New onset NAFLD/NASH occurred in 20% and EPI in 49% of patients. Multivariate analysis showed that the only risk factor for new onset NAFLD/NASH was recurrent disease (OR 4.4, 95% CI 1.1-16.8, P = 0.031), but not EPI (OR 0.94, 95% CI 0.3-2.8, P = 0.911). The only risk factor for EPI was pancreatoduodenectomy (OR 4.3, 95% CI 1.4-13.7, P = 0.012). CONCLUSIONS: New onset NAFLD/NASH is occasionally found after pNET resection, especially in patients with recurrent disease, but is not related to EPI. PMID- 29572826 TI - Differential effects of vision upon the accuracy and precision of vestibular evoked balance responses. AB - KEY POINTS: Effective balance control requires the transformation of vestibular signals from head- to foot-centred coordinates in order to move the body in an appropriate direction. This transformation process has previously been studied by analysing the directional accuracy of the averaged sway response to multiple electrical vestibular stimuli (EVS). Here we studied trial-by-trial variability of EVS responses to measure any changes in directional precision which may be masked by the averaging process. We found that vision increased directional variability without influencing the mean sway direction, demonstrating that response accuracy and precision are dissociable. These results emphasise the importance of single trial analysis in determining the efficacy of vestibular control of balance. ABSTRACT: Vestibular information must be transformed from head- to-foot-centred coordinates for balance control. This transformation process has previously been investigated using electrical vestibular stimulation (EVS), which evokes a sway response fixed in head coordinates. The craniocentric nature of the response has been demonstrated by analysing average responses to multiple stimuli. This approach misses any trial-by-trial variability which would reflect poor balance control. Here we performed single-trial analysis to measure this directional variability (precision), and compared this to mean performance (accuracy). We determined the effect of vision upon both parameters. Standing volunteers adopted various head orientations (0, +/-30 and +/-60 deg yaw) while EVS-evoked response direction was determined from ground reaction force vectors. As previously reported, mean force direction was orientated towards the anodal ear, and rotated in line with head yaw. Although vision caused a ~50% reduction in response magnitude, it had no influence on the direction of the mean sway response, indicating that accuracy was unaffected. However, individual trial analysis revealed up to 30% increases in directional variability with the eyes open. This increase was inversely correlated with the size of the force response. The paradoxical observation that vision reduces the precision of the balance response may be explained by a multi-sensory integration process. As additional veridical sensory information becomes available, this lessens the relative contribution of vestibular input, causing a simultaneous reduction in both the magnitude and the precision of the response to EVS. Our novel approach demonstrates the importance of single-trial analysis in revealing the efficacy of vestibular reflexes. PMID- 29572827 TI - Activity-dependent synaptic integration and modulation of bilateral excitatory inputs in an auditory coincidence detection circuit. AB - KEY POINTS: Binaural excitatory inputs to coincidence detection neurons in nucleus laminaris (NL) play essential roles in interaural time difference coding for sound localization. Here, we show that the two excitatory inputs are physiologically nearly completely segregated. Synaptic integration shows linear summation of EPSPs, ensuring high efficiency of coincidence detection of the bilateral excitatory inputs. We further show that the two excitatory inputs to single NL neurons are symmetrical in synaptic strength, kinetics and short-term plasticity. Modulation of the EPSCs by metabotropic glutamate receptors (mGluRs) is identical between the two excitatory inputs, maintaining balanced bilateral excitation under neuromodulatory conditions. Unilateral hearing deprivation reduces synaptic excitation and paradoxically strengthens mGluR modulation of EPSCs, suggesting activity-dependent anti-homeostatic regulation, a novel synaptic plasticity in response to sensory manipulations. ABSTRACT: Neurons in the avian nucleus laminaris (NL) receive bilateral excitatory inputs from the cochlear nucleus magnocellularis, via morphologically symmetrical dorsal (ipsilateral) and ventral (contralateral) dendrites. Using in vitro whole-cell patch recordings in chicken brainstem slices, we investigated synaptic integration and modulation of the bilateral inputs to NL under normal and hearing deprivation conditions. We found that the two excitatory inputs onto single NL neurons were nearly completely segregated, and integration of the two inputs was linear for EPSPs. The two inputs had similar synaptic strength, kinetics and short-term plasticity. EPSCs in low but not middle and high frequency neurons were suppressed by activation of group I and II metabotropic glutamate receptors (mGluR I and II), with similar modulatory strength between the ipsilateral and contralateral inputs. Unilateral hearing deprivation by cochlea removal reduced the excitatory transmission on the deprived dendritic domain of NL. Interestingly, EPSCs evoked at the deprived domain were modulated more strongly by mGluR II than at the counterpart domain that received intact input in low frequency neurons, suggesting anti-homeostatic regulation. This was supported by a stronger expression of mGluR II protein on the deprived neuropils of NL. Under mGluR II modulation, EPSCs on the deprived input show transient synaptic facilitation, forming a striking contrast with normal hearing conditions under which pure synaptic depression is observed. These results demonstrate physiological symmetry and thus balanced bilateral excitatory inputs to NL neurons. The activity-dependent anti-homeostatic plasticity of mGluR modulation constitutes a novel mechanism regulating synaptic transmission in response to sensory input manipulations. PMID- 29572828 TI - The prognostic impact of differentiation at the invasive front of biliary tract cancer. AB - BACKGROUND: The invasive front of tumor can provide prognostic information in many cancers. We investigated the prognostic morphological factors at the invasive front including tumor differentiation (Difinv ) and tumor budding (Bud) in biliary tract cancer (BTC). METHODS: The resected specimen from the 299 BTC patients were examined. Intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, gallbladder cancer, and ampulla of Vater cancer were found in 16%, 48%, 17%, and 19%, respectively. Difinv grade (G) 3 and Bud foci >=5 were found in 47% and 10%. Tumor with Difinv G3 showed the high frequencies of Bud, vascular invasion (Ve) and nodal metastasis (LN) compared to tumor with Difinv G1/2 (Bud: 21% vs 0%, Ve: 71% vs 50%, LN: 52% vs 36%). Multivariate analysis revealed that the independent predictors were Difinv G3 (HR: 1.71), Bud foci >=5 (HR: 2.14), Ve (HR: 1.56) and LN (HR: 2.59) in overall survival and were positive resection margin (HR: 1.71), Difinv G3 (HR: 1.75), Ve (HR: 1.50), and LN (HR: 2.19) in relapse free survival. CONCLUSION: Poor differentiation at the invasive front of tumor was associated with poor prognosis and early relapse in BTC patients. PMID- 29572830 TI - Overview on mitigation of acrylamide in starchy fried and baked foods. AB - Acrylamide in fried and baked foods has the potential to cause toxic effects in animals and humans. A major challenge lies in developing an effective strategy for acrylamide mitigation in foods without altering its basic properties. Food scientists around the world have developed various methods to mitigate the presence of acrylamide in fried food products. Mitigation techniques using additives such as salts, amino acids, cations and organic acids along with blanching of foods have reduced the concentration of acrylamide. The use of secondary metabolites such as polyphenols also reduces acrylamide concentration in fried food products. Other mitigation techniques such as asparaginase pre treatment and low-temperature air frying with chitosan have been effective in mitigating the concentration of acrylamide. The combined pre-treatment process along with the use of additives is the latest trend in acrylamide mitigation. (c) 2018 Society of Chemical Industry. PMID- 29572829 TI - Time and sex dependent effects of magnesium sulphate on post-asphyxial seizures in preterm fetal sheep. AB - KEY POINTS: We evaluated the effect of magnesium sulphate (MgSO4 ) on seizures induced by asphyxia in preterm fetal sheep. MgSO4 did not prevent seizures, but significantly reduced the total duration, number of seizures, seizure amplitude and average seizure burden. Saline-asphyxia male fetuses had significantly more seizures than female fetuses, but male fetuses showed significantly greater reduction in seizures during MgSO4 infusion than female fetuses. A circadian profile of seizure activity was observed in all fetuses, with peak seizures seen around 04.00-06.00 h on the first and second days after the end of asphyxia. This study is the first to demonstrate that MgSO4 has utility as an anti-seizure agent after hypoxia-ischaemia. More information is needed about the mechanisms mediating the effect of MgSO4 on seizures and sexual dimorphism, and the influence of circadian rhythms on seizure expression. ABSTRACT: Seizures are common in newborns after asphyxia at birth and are often refractory to anti seizure agents. Magnesium sulphate (MgSO4 ) has anticonvulsant effects and is increasingly given to women in preterm labour for potential neuroprotection. There is limited information on its effects on perinatal seizures. We examined the hypothesis that MgSO4 infusion would reduce fetal seizures after asphyxia in utero. Preterm fetal sheep at 0.7 gestation (104 days, term = 147 days) were given intravenous infusions of either saline (n = 14) or MgSO4 (n = 12, 160 mg bolus + 48 mg h-1 infusion over 48 h). Fetuses underwent umbilical cord occlusion (UCO) for 25 min, 24 h after the start of infusion. The start time for seizures did not differ between groups, but MgSO4 significantly reduced the total number of seizures (P < 0.001), peak seizure amplitude (P < 0.05) and seizure burden (P < 0.005). Within the saline-asphyxia group, male fetuses had significantly more seizures than females (P < 0.05). Within the MgSO4 -asphyxia group, although both sexes had fewer seizures than the saline-asphyxia group, the greatest effect of MgSO4 was on male fetuses, with reduced numbers of seizures (P < 0.001) and seizure burden (P < 0.005). Only 1 out of 6 MgSO4 males had seizures on the second day post-UCO compared to 5 out of 6 MgSO4 female fetuses (P = 0.08). Finally, seizures showed a circadian profile with peak seizures between 04.00 and 06.00 h on the first and second day post-UCO. Collectively, these results suggest that MgSO4 may have utility in treating perinatal seizures and has sexually dimorphic effects. PMID- 29572831 TI - The impact of proteinuria on maternal and perinatal outcomes among women with pre eclampsia. AB - OBJECTIVE: To assess the impact of proteinuria on pregnancy outcomes among women with pre-eclampsia. METHODS: The present retrospective cohort study included patients with pre-eclampsia who delivered at a referral maternity hospital in Brazil between January 1, 2009, and December 31, 2013. Patients were stratified into three groups based on 24-hour urinary protein excretion during pregnancy: mild (0.3-<2.0 g), severe (2.0-<5.0 g), and massive (>=5.0 g). RESULTS: There were 293 patients included in the study; 88, 129, and 76 had mild, severe, and massive proteinuria, respectively. Chronic hypertension was the most frequent pre existing condition among all women (86 [29.4%]). The mean pregnancy duration at the onset of maternal pre-eclampsia was longest in the mild group compared and decreased with increasing proteinuria severity (P<0.001). Preterm delivery was recorded among 205 of 293 (70.0%) neonates; there were 66 (22.5%) neonates that were preterm and in the massive proteinuria group. The incidence of severe pre eclampsia was lowest in the mild proteinuria group (P=0.002) and tended to occur at 34 weeks. Cesarean delivery rates exceeded 80.0% in all groups. Most patients assessed at 40-60 days postpartum remained proteinuric (40/61[66%]). CONCLUSIONS: Quantifying the severity of proteinuria could identify a subgroup of women with pre-eclampsia at increased risk of adverse outcomes. PMID- 29572832 TI - When muscle Ca2+ channels carry monovalent cations through gating pores: insights into the pathophysiology of type 1 hypokalaemic periodic paralysis. AB - Patients suffering from type 1 hypokalaemic periodic paralysis (HypoPP1) experience attacks of muscle paralysis associated with hypokalaemia. The disease arises from missense mutations in the gene encoding the alpha1 subunit of the dihydropyridine receptor (DHPR), a protein complex anchored in the tubular membrane of skeletal muscle fibres which controls the release of Ca2+ from sarcoplasmic reticulum and also functions as a Ca2+ channel. The vast majority of mutations consist of the replacement of one of the outer arginines in S4 segments of the alpha1 subunit by neutral residues. Early studies have shown that muscle fibres from HypoPP1 patients are abnormally depolarized at rest in low K+ to the point of inducing muscle inexcitability. The relationship between HypoPP1 mutations and depolarization has long remained unknown. More recent investigations conducted in the closely structurally related voltage-gated Na+ and K+ channels have shown that comparable S4 arginine substitutions gave rise to elevated inward currents at negative potentials called gating pore currents. Experiments performed in muscle fibres from different models revealed such an inward resting current through HypoPP1 mutated Ca2+ channels. In mouse fibres transfected with HypoPP1 mutated channels, the elevated resting current was found to carry H+ for the R1239H arginine-to-histidine mutation in a S4 segment and Na+ for the V876E HypoPP1 mutation, which has the peculiarity of not being located in S4 segments. Muscle paralysis probably results from the presence of a gating pore current associated with hypokalaemia for both mutations, possibly aggravated by external acidosis for the R1239H mutation. PMID- 29572833 TI - New nomogram predicts the recurrence of hepatocellular carcinoma in patients with negative preoperative serum AFP subjected to curative resection. AB - BACKGROUND: There is currently no established model for predicting the recurrence of hepatocellular carcinoma (HCC) in patients with negative alpha-fetoprotein (AFP) after curative resection. Therefore, the objective of this study was to establish a nomogram to identify the risk of recurrence in AFP-negative (=500 mL) and Deltavolume as positive(>254.49 mL), unchanged(>= 268.77-<= 254.49 mL), or negative(<-268.77 mL). Futhermore, we analyzed clinical effectiveness, pleural elastance, and adverse events. RESULTS: A total of 87 patients were analyzed. Pleural volume varied from 35-2750 mL in iCT and from 0 2995 mL in CT30(P = 0.753). A total of 54 patients had initial small pleural space(62.06%) and 33 large(37.93%). Clinical failure occurred in 7.4% of small space group and in 24.6% of large(P = 0.051, OR4.0(CI:1.098-14.570)). In small space group, 27.77% evolved with positive, 66.66% with unchanged and 5.55% with negative Deltavolume. In the large space group these numbers were respectively 21.21%, 27.27%, and 51.51%. CONCLUSIONS: There is significant variability on pleural space volume. However, pleural volume remains unchanged in many cases. Besides that, more than half patients with initial large space coursed with relevant reduction. Finally, patients with initial small space presented a greater chance of clinical success. PMID- 29572838 TI - Efficacy of prophylactic probiotics in combination with antibiotics versus antibiotics alone for colorectal surgery: A meta-analysis of randomized controlled trials. AB - This meta-analysis aimed to determine whether prophylactic probiotics in combination with antibiotics are superior to antibiotics alone in the prevention of surgical site infection (SSI) after colorectal surgery. Fourteen trials involving 1524 participants were included. Compared with antibiotics alone, prophylactic probiotics in combination with antibiotics reduced the risk of SSI as well as other complications, shortened the cumulative duration of antibiotic therapy. Current evidence suggested that probiotics in combination with antibiotics could be recommended. PMID- 29572839 TI - Alcohol intake and periodontitis in adults aged >=30 years: NHANES 2009-2012. AB - BACKGROUND: Whether an association between alcohol consumption and periodontitis exists is still unclear. This study aimed to assess the association between alcohol consumption and periodontitis. METHODS: 7062 adults 30 years or older who participated in 2009-2010 and 2011-2012 cycles of the National Health and Nutrition Examination Survey (NHANES) were included. Alcohol consumption measurement included self-reported average number of alcoholic drinks per week over the previous 12 months and was categorized into four groups (0, < 1, 1- < 8, and >=8 drinks per week). Participants were categorized using surveillance case definitions for periodontitis that included both clinical attachment level (CAL) and periodontal probing depth (PD) measurements. The association between alcohol consumption and chronic periodontitis was evaluated by multivariable regression analyses adjusting for age, gender, race/ethnicity, education level, income-to poverty ratio, smoking, self-rated overall oral health, and HbA1c . RESULTS: The odds ratio (95% confidence interval) of having severe periodontitis was 1.9 (1.2 3) among participants who reported alcohol consumption of >=8 drinks compared to participants consuming some alcohol but < 1 drink per week on average. Participants who consumed 1- < 8, and >=8 drinks per week, on average, also had higher mean PD, percentage of sites with PD >=4 mm, mean CAL, and percentage of sites with CAL >=3 mm compared to participants reporting consumption of < 1 drink per week. Meanwhile, the odds of having periodontitis, mean PD, extent PD >=4 mm, mean CAL, and extent CAL >=3 mm were not significantly different for nondrinkers than for participants who consumed some alcohol but < 1 drink per week on average. CONCLUSIONS: Alcohol consumption was associated with an increase in the likelihood of having periodontitis, particularly severe periodontitis. Consumption of some alcohol, < 1 drink per week on average, was associated with similar odds of having periodontitis compared to consumption of no alcohol. PMID- 29572837 TI - Cholecystokinin selectively activates short axon cells to enhance inhibition of olfactory bulb output neurons. AB - KEY POINTS: Cholecystokinin (CCK) via CCK-B receptors significantly enhances the GABAA receptor-mediated synaptic inhibition of principal olfactory bulb (OB) output neurons. This CCK action requires action potentials in presynaptic neurons. The enhanced inhibition of OB output neurons is a result of CCK-elevated inhibitory input from the glomerular circuit. CCK modulation of the glomerular circuit also leads to potentiated presynaptic inhibition of olfactory nerve terminals and postsynaptic inhibition of glomerular neurons. Selective excitation of short axon cells underlies the CCK-potentiated glomerular inhibition. ABSTRACT: Neuropeptides such as cholecystokinin (CCK) are important for many brain functions, including sensory processing. CCK is predominantly present in a subpopulation of excitatory neurons and activation of CCK receptors is implicated in olfactory signal processing in the olfactory bulb (OB). However, the cellular and circuit mechanisms underlying the actions of CCK in the OB remain elusive. In the present study, we characterized the effects of CCK on synaptic inhibition of the principal OB output neurons mitral/tufted cells (MTCs) followed by mechanistic analyses at both circuit and cellular levels. First, we found that CCK via CCK-B receptors enhances the GABAA receptor-mediated spontaneous IPSCs in MTCs. Second, CCK does not affect the action potential independent miniature IPSCs in MTCs. Third, CCK potentiates glomerular inhibition resulting in increased GABAB receptor-mediated presynaptic inhibition of olfactory nerve terminals and enhanced spontaneous IPSCs in MTCs and glomerular neurons. Fourth, CCK enhances miniature IPSCs in the excitatory external tufted cells, although neither in the inhibitory short axon cells (SACs) nor in periglomerular cells (PGCs). Finally, CCK excites all tested SACs and a very small minority of GABAergic neurons in the granule cell layer or in periglomerular cells, but not in deep SACs. These results demonstrate that CCK selectively activates SACs to engage the SAC-formed interglomerular circuit and thus elevates inhibition broadly in the OB glomerular layer. This modulation may prevent the system from saturating in response to a high concentration of odourants or facilitate the detection of weak stimuli by increasing signal-to-noise ratio.

AB - Wood biosynthesis defines the chemical and structural properties of wood. The metabolic pathways that produce the precursors of wood cell wall polymers have a central role in defining wood properties. To make rational design of wood properties feasible, we need not only to understand the cell wall biosynthetic machinery, but also how sucrose transport and metabolism in developing wood connect to cell wall biosynthesis and how they respond to genetic and environmental cues. Here, we review the current understanding of the sucrose transport and primary metabolism pathways leading to the precursors of cell wall biosynthesis in woody plant tissues. We present both old, persistent questions and new emerging themes with a focus on wood formation in trees and draw upon evidence from the xylem tissues of herbaceous plants when it is relevant.

AB - Diabetic peripheral neuropathy is one of the most common microvascular complications that occurs with both type 1 and type 2 diabetes mellitus. It has a significant negative impact on patients' quality of life; as it starts with loss of limbs' sensation and may lead to lower limb amputation. This study aimed at investigating the effect of liraglutide on peripheral neuropathy in diabetic rats. Experimental diabetes was induced by single intraperitoneal injections of nicotinamide (50 mg/kg) and streptozotocin (52.5 mg/kg). Rats were allocated into five groups. Two groups were given saline or liraglutide (0.8 mg/kg, s.c.). Three diabetic groups were either untreated or treated with liraglutide (0.8 mg/kg, s.c.) or pregabalin (10 mg/kg, i.p.). After 2 weeks of treatment, behavioral, biochemical, histopathological, and immunohistochemical investigations were performed. Treatment with liraglutide-restored animals' body weight, normalized blood glucose, decreased glycated hemoglobin, and increased insulin levels. In parallel, it normalized motor coordination and the latency withdrawal time of both tail flick and hind paw cold allodynia tests and reversed histopathological alterations. Treatment with liraglutide also normalized malondialdehyde, matrix metalloproteinase-2 and -9 contents in sciatic nerve. Likewise, it decreased sciatic nerve nitric oxide and interleukin-6 contents, DNA fragmentation and expression of cyclooxygenase-2. Meanwhile, it increased superoxide dismutase and interleukin-10 contents in sciatic nerve. These findings indicate the neuroprotective effect of liraglutide against diabetic peripheral neuropathy probably via modulating oxidative stress, inflammation, and extracellular matrix remodeling.

AB - BACKGROUND: Historically, allergic contact dermatitis caused by hexavalent chromium [Cr(VI)] in cement was the most common cause of invalidity attributable to skin disease in Sweden. Since the legislation to reduce Cr(VI) in cement was introduced in 1989, we rarely see allergic contact dermatitis caused by cement. OBJECTIVES: To examine the frequency of contact allergy to Cr(VI) in southern Sweden in 2005-2014. METHODS: We investigated the occurrence of positive reactions to potassium dichromate 0.5% pet. in consecutively tested dermatitis patients, and compared the occurrence of atopic dermatitis, localization of dermatitis and simultaneous positive reactions to cobalt chloride and nickel sulfate in the Cr(VI)-positive patients with those in a group of patients with a similar age and sex distribution. RESULTS: In total, 6482 patients were tested, and 233 Cr(VI)-allergic individuals were found (3.6%). A significantly higher proportion of atopic dermatitis was found among Cr(VI)-allergic patients, and a significantly higher share of foot dermatitis was found among Cr(VI)-allergic women, than among controls. Cr(VI) allergy was less likely when both nickel allergy and cobalt allergy were present. CONCLUSION: A relatively high frequency of contact allergy to Cr(VI) was found. The cause has shifted from cement exposure to other exposures, probably mainly leather. PMID- 29572845 TI - Magnesium promotes root nodulation through facilitation of carbohydrate allocation in soybean. AB - Magnesium (Mg) is an essential element for the growth of both plants and bacteria. Low availability of Mg in agriculture can limit crop productivity and quality. In addition to direct effects on plant growth, limited Mg supply may also impact biological dinitrogen (N2 ) fixation in nodules formed from symbiotic interactions between legumes and rhizobial bacteria. To date, the physiological mechanisms involved in Mg-dependent nodulation remains largely unknown. The objectives of this work were to assess how Mg supply affects nodule growth and development in symbiotic systems, and to test if any observed changes in nodule and soybean are correlated with Mg supply. Here, we found that external Mg supply enhanced nodule growth under nitrogen (N) limited conditions, and subsequently improved N2 fixation and soybean growth. Mg supply altered neither nodule structure nor Mg homeostasis, but remarkably promoted nodule enlargement, resulting in an increase in the number of big nodules. In addition, high Mg supply decreased starch and sucrose accumulation in leaves, and increased their concentrations in roots, which consequently enhanced carbohydrate import into the rhizobia infection zone of nodules. In this study, Mg was shown to promote nodule growth in soybean. This Mg-promoted nodule growth is derived from Mg-facilitated alteration of carbohydrate partitioning and transport into nodules.

AB - INTRODUCTION: Peanut stems and leaves (PSL) have traditionally been used as both a special food and a herbal medicine in Asia. The sedative-hypnotic and anxiolytic effects of PSL have been recorded in classical traditional Chinese literature, and more recently by many other researchers. In a previous study, four sleep-related ingredients (linalool, 5-hydroxy-4',7-dimethoxyflavanone, 2'-O methylisoliquiritigenin and ferulic acid), among which 5-hydroxy-4',7 dimethoxyflavanone and 2'-O-methylisoliquiritigenin were newly found in Arachis species, were screened by ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC/QTOF-MS). In the current study, quantitative examination of the above four ingredients was conducted. Serious fundamental functional studies were done in mice, including locomotor activity, direct sleep tests, pentobarbital-induced sleeping time tests, subthreshold dose of pentobarbital tests and barbital sodium sleep incubation period tests, to determine the material base for the sedative-hypnotic and anxiolytic effects of aqueous extracts of PSL. Furthermore, neurotransmitter levels in three brain regions (cerebrum, cerebellum and brain stem) were determined using UHPLC coupled with triple-quadrupole mass spectrometry (UHPLC/QQQ-MS) in order to elucidate the exact mechanism of action. RESULTS: Aqueous extract of PSL at a dose of 500 mg kg-1 (based on previous experience), along with different concentrations of the above four functional ingredients (189.86 ug kg-1 linalool, 114.75 mg kg-1 5-hydroxy-4',7-dimethoxyflavanone, 32.4mg kg-1 2'-O-methylisoliquiritigenin and 44.44 mg kg-1 ferulic acid), had a sedative-hypnotic effect by affecting neurotransmitter levels in mice. CONCLUSION: The data demonstrate that these four ingredients are the key functional factors for the sedative-hypnotic and anxiolytic effects of PSL aqueous extracts and that these effects occur via changes in neurotransmitter levels and pathways.

AB - PURPOSE: Recent developments in iterative image reconstruction enable absolute quantification of SPECT/CT studies by incorporating compensation for collimator detector response, attenuation, and scatter as well as resolution recovery into the reconstruction process (Evolution; Q.Metrix package; GE Healthcare, Little Chalfont, UK). The aim of this experimental study is to assess its quantitative accuracy for potential clinical 99m Tc-sestamibi (MIBI)-related SPECT/CT application in neoadjuvant chemotherapy response studies in breast cancer. METHODS: Two phantoms were filled with MIBI and acquired on a SPECT/CT gamma camera (Discovery 670 Pro; GE Healthcare), that is, a water cylinder and a NEMA body phantom containing six spheres that were filled with an activity concentration reflecting clinical MIBI uptake. Subsequently, volumes-of-interest (VOI) of each sphere were drawn (semi)automatically on SPECT using various isocontour methods or manually on CT. Finally, prone MIBI SPECT/CT scans were acquired 5 and 90 min p.i. in a locally advanced breast cancer patient. RESULTS: Activity concentration in the four largest spheres converged after nine iterations of evolution. Depending on the count statistics, the accuracy of the reconstructed activity concentration varied between -4.7 and -0.16% (VOI covering the entire phantom) and from 6.9% to 10% (8.8 cm ? cylinder VOI placed in the center of the phantom). Recovery coefficients of SUVmax were 1.89 +/- 0.18, 1.76 +/- 0.17, 2.00 +/- 0.38, 1.89 +/- 0.35, and 0.90 +/- 0.26 for spheres with 37, 28, 22, 17, and 13 mm ?, respectively. Recovery coefficients of SUVmean were 1.07 +/- 0.06, 1.03 +/- 0.09, 1.17 +/- 0.21, 1.10 +/- 0.20, and 0.52 +/- 0.14 (42% isocontour); 1.10 +/- 0.07, 1.02 +/- 0.09, 1.13 +/- 0.19, 1.06 +/- 0.19, and 0.51 +/- 0.13 (36% isocontour with local background correction); and 0.96, 1.09, 1.03, 1.03, and 0.29 (CT). Patient study results were concordant with the phantom validation. CONCLUSIONS: Absolute SPECT/CT quantification of breast studies using MIBI seems feasible (<17% deviation) when a 42% isocontour is used for delineation for tumors of at least 17 mm diameter. However, with tumor shrinkage, response evaluation should be handled with caution, especially when using SUVmax . PMID- 29572849 TI - The role of C2H2 zinc finger proteins in plant responses to abiotic stresses. AB - Abiotic stresses are important factors affecting plant growth and development and limiting agricultural production worldwide. Plants have evolved complex regulatory mechanisms to respond and adapt to constantly changing environmental conditions. C2H2 zinc finger proteins form a relatively large family of transcriptional regulators in plants. Recent studies have revealed that C2H2 zinc finger proteins function as key transcriptional regulators in plant responses to a wide spectrum of stress conditions, including extreme temperatures, salinity, drought, oxidative stress, excessive light and silique shattering. Here, we summarize recent functional analysis on C2H2 zinc finger proteins in plant responses to abiotic stresses and discuss their roles as part of a large regulatory network in the perception and responses by plants to different environmental stimuli.

AB - OBJECTIVES: To determine outcomes of minor urological surgery in frail older adults. DESIGN: Retrospective cohort study. SETTING: U.S. nursing homes (NHs). PARTICIPANTS: NH residents aged 65 and older undergoing minor inpatient urological surgery (cystoscopy, bladder biopsy, transurethral resection of bladder tumor, prostate biopsy, transurethral resection of prostate, removal of ureteral obstruction, suprapubic tube placement) in the United States between 2004 and 2012 (N=34,605). MEASUREMENTS: One-year mortality and changes in functional status before and after surgery using the Minimum Data Set Activity of Daily Living (MDS-ADL) summary scale. RESULTS: Overall 1-year mortality was 50%, and on average, residents had a 1.9-point worsening in their MDS-ADL score at 1 year, whereas the most highly functional residents (baseline quartile of MDS-ADL scores (0-12)) had a 4.7-point worsening in their MDS-ADL scores at 1 year. Functional decline in residents 1 year after surgery was associated with decline in function in the 6 months before surgery (adjusted hazard ratio (aH)=2.39, 95% confidence interval (CI)=2.29-2.49), emergency procedures (aHR=1.37, 95% CI=1.31 1.43), older age (>=85 vs 65-74, aHR=1.17, 95% CI=1.11-1.23), and baseline cognitive impairment (aHR=1.15, 95% CI=1.11-1.20). CONCLUSION: Despite the low complexity of minor urological procedures, NH residents experience high mortality and many demonstrate sustained functional decline up to 1-year postoperatively. PMID- 29572852 TI - Detecting violation in abstract pitch patterns with mismatch negativity. AB - The human brain automatically extracts regularities embedded in environmental auditory events. This study investigated the extraction of abstract patterns by measuring mismatch negativity (MMN). Participants watched a silent subtitled movie and ignored a sequence of auditory events comprising frequent standards and rare deviants presented in the background. Tone triplets with varying pitch (first-order property) served as the auditory events. The pitch intervals (interval 1 and interval 2) between the tones in a triplet and the ratio of interval 1 and 2 were considered second- and third-order properties, respectively. Both second- and third-order properties of the standards were kept constant in the mixed patterns block, while only the third-order property was kept constant in the ratio pattern block. Four sets of tone triplets violating the interval and ratio patterns with different deviance levels were presented as deviants in both blocks, and subtracted with physically identical stimuli in a control block to isolate the MMNs. Interval and ratio pattern deviants elicited MMNs in the mixed patterns block while only ratio pattern deviants elicited MMNs in the ratio pattern block. Larger MMNs were elicited by large deviants as compared to small deviants. These results suggest that the change detection system is sensitive to the violation of both second- and third-order abstract patterns. In addition to regularities in the abstract properties of auditory events, regularities in the relationships between abstract properties can also be extracted. This ability plays an important role in music and language perception. PMID- 29572853 TI - Plant and algal structure: from cell walls to biomechanical function. AB - Plant and algal cell walls are complex biomaterials composed of stiff cellulose microfibrils embedded in a soft matrix of polysaccharides, proteins and phenolic compounds. Cell wall composition differs between taxonomic groups and different tissue types (or even at the sub-cellular level) within a plant enabling specific biomechanical properties important for cell/tissue function. Moreover, cell wall composition changes may be induced in response to environmental conditions. Plant structure, habit, morphology and internal anatomy are also dependent on the taxonomic group as well as abiotic and biotic factors. This review aims to examine the complex and incompletely understood interactions of cell wall composition, plant form and biomechanical function.

PMID- 29572856 TI - The relative biological effectiveness for carbon, nitrogen, and oxygen ion beams using passive and scanning techniques evaluated with fully 3D silicon microdosimeters. AB - BACKGROUND: The aim of this study was to measure the microdosimetric distributions of a carbon pencil beam scanning (PBS) and passive scattering system as well as to evaluate the relative biological effectiveness (RBE) of different ions, namely 12 C, 14 N, and 16 O, using a silicon-on-insulator (SOI) microdosimeter with well-defined 3D-sensitive volumes (SV). Geant4 simulations were performed with the same experimental setup and results were compared to the experimental results for benchmarking. METHOD: Two different silicon microdosimeters with rectangular parallelepiped and cylindrical shaped SVs, both 10 MUm in thickness were used in this study. The microdosimeters were connected to low noise electronics which allowed for the detection of lineal energies as low as 0.15 keV/MUm in tissue. The silicon microdosimeters provide extremely high spatial resolution and can be used for in-field and out-of-field measurements in both passive scattering and PBS deliveries. The response of the microdosimeters was studied in 290 MeV/u 12 C, 180 MeV/u 14 N, 400 MeV/u 16 O passive ion beams, and 290 MeV/u 12 C scanning carbon therapy beam at heavy ion medical accelerator in Chiba (HIMAC) and Gunma University Heavy Ion Medical Center (GHMC), Japan, respectively. The microdosimeters were placed at various depths in a water phantom along the central axis of the ion beam, and at the distal part of the Spread Out Bragg Peak (SOBP) in 0.5 mm increments. The RBE values of the pristine Bragg peak (BP) and SOBP were derived using the microdosimetric lineal energy spectra and the modified microdosimetric kinetic model (MKM), using MKM input parameters corresponding to human salivary gland (HSG) tumor cells. Geant4 simulations were performed in order to verify the calculated depth-dose distribution from the treatment planning system (TPS) and to compare the simulated dose-mean lineal energy to the experimental results. RESULTS: For a 180 MeV/u 14 N pristine BP, the dose-mean lineal energy yD- obtained with two types of silicon microdosimeters started from approximately 29 keV/MUm at the entrance to 92 keV/MUm at the BP, with a maximum value in the range of 412 to 438 keV/MUm at the distal edge. For 400 MeV/u 16 O ions, the dose-mean lineal energy yD- started from about 24 keV/MUm at the entrance to 106 keV/MUm at the BP, with a maximum value of approximately 381 keV/MUm at the distal edge. The maximum derived RBE10 values for 14 N and 16 O ions were found to be 3.10 +/- 0.47 and 2.93 +/- 0.45, respectively. Silicon microdosimetry measurements using pencilbeam scanning 12 C ions were also compared to the passive scattering beam. CONCLUSIONS: These SOI microdosimeters with well-defined three-dimensional (3D) SVs have applicability in characterizing heavy ion radiation fields and measuring lineal energy deposition with sub-millimeter spatial resolution. It has been shown that the dose-mean lineal energy increased significantly at the distal part of the BP and SOBP due to very high LET particles. Good agreement was observed for the experimental and simulation results obtained with silicon microdosimeters in 14 N and 16 O ion beams, confirming the potential application of SOI microdosimeter with 3D SV for quality assurance in charged particle therapy. PMID- 29572857 TI - Comparison of reactivity to a metallic disc and 2% aluminium salt in 366 children, and reproducibility over time for 241 young adults with childhood vaccine-related aluminium contact allergy. AB - BACKGROUND: An aluminium hydroxide-adsorbed pertussis toxoid vaccine was studied in 76 000 children in the 1990s in Gothenburg, Sweden. Long-lasting itchy subcutaneous nodules at the vaccination site were seen in 745 participants. Of 495 children with itchy nodules who were patch tested for aluminium allergy, 377 were positive. In 2007-2008, 241 of the positive children were retested. Only in one third were earlier positive results reproduced. OBJECTIVES: To further describe patch test reactions to different aluminium compounds in children with vaccine-induced aluminium allergy. PATIENTS/METHODS: Positive patch test results for metallic aluminium (empty Finn Chamber) and aluminium chloride hexahydrate 2% petrolatum (pet.) were analysed in 366 children with vaccine-induced persistent itching nodules tested in 1998-2002. Of those, 241 were tested a second time (2007-2008), and the patch test results of the two aluminium preparations were analysed. RESULTS: Patch testing with aluminium chloride hexahydrate 2% pet. is a more sensitive way to diagnose aluminium contact allergy than patch testing with metallic aluminium. A general decrease in the strength of reactions to both aluminium preparations in 241 children tested twice was observed. CONCLUSIONS: Aluminium contact allergy can be diagnosed by patch testing without using metallic aluminium. PMID- 29572858 TI - Red blood cell transfusion in perioperative pediatric anesthesia: a survey of current practice in Germany. AB - BACKGROUND: Little is known about the current practice of the perioperative transfusion of red blood cells (RBCs) in pediatric patients. This study was performed to evaluate the practice of RBC transfusion in German pediatric anesthesia. STUDY DESIGN AND METHODS: An online survey was conducted among members of the German Society of Anesthesiology and Intensive Care. Participants were asked to indicate the hemoglobin (Hb) thresholds for starting RBC transfusion in six cases of different bleeding situations in pediatric anesthesia. Demographics of participants, general knowledge, and application of transfusion rules and guidelines were assessed. RESULTS: We included 1207 of 1396 returned questionnaires. Of the respondents, 89% were qualified specialists and 68% had experience in anesthesia in children aged less than 6 months. The lowest median Hb transfusion threshold was 6 g/dL in a 16-year-old and the highest was 10 g/dL in a premature neonate. Intraoperative Hb thresholds increased for clinically unstable (median difference to clinically stable children, +1 g/dL; p < 0.001) or neonate and premature children (median difference to older children, +1 and +2 g/dL; p < 0.001). The stated Hb threshold ranges were broad, especially in neonates or premature children (interquartile range, neonates 3, premature children 4 g/dL). Of the participants, only 16% had knowledge of a guideline that includes blood transfusion in children. CONCLUSION: Striking variability exists in practice of perioperative pediatric RBC transfusion. A specialized guideline for perioperative blood transfusion in children could be helpful to define and promote optimal pediatric RBC transfusion strategies. PMID- 29572859 TI - Blood donors' preferences for blood donation for biomedical research. AB - BACKGROUND: Increasing numbers of blood donors are recruited to participate in biomedical research. As blood services depend on voluntary donors, successful recruitment calls for a better understanding of donors' expectations and attitudes toward the use of samples in research. STUDY DESIGN AND METHODS: Sixty one semistructured interviews were conducted with blood donors at eight Finnish Red Cross Blood Service donation sites in Finland. The 10- to 30-minute interviews included open-ended questions about donors' views on blood donation for patients and for biomedical research. Central motives to donate blood for patients were identified against which views on research use were compared to see how these reflections differed. RESULTS: Six central motives for donating blood for patients were identified among donors. The interviewees were, in general, willing to donate blood for research, but considered research donation more likely if it could be easily integrated into their usual blood donation habits. Biomedical research was perceived as important but its social benefits were more abstract than a direct help to patients. CONCLUSIONS: Familiarity and reciprocity were key to the relationship between the blood service and blood donors. Donation for research introduces a new, more complex context to blood donation. Challenge to recognize concrete outcomes and benefits of donation may affect willingness to donate for research. Transparent communication of the role of the blood service in research and of the beneficiaries of the research is essential in maintaining trust. These results will help blood services in their planning to recruit blood donors for research projects. PMID- 29572860 TI - Organic iodine supply affects tomato plants differently than inorganic iodine. AB - Iodine is a beneficial element for humans but very lowly represented in our diet. Iodine-enriched vegetables could boost the iodine content in the food chain. Despite being a beneficial element for plants, little is known about the effect of different iodine forms on plant growth. This work analyses the effect of uptake of mineral (KI) and organoiodine (5-iodosalicylic acid, 5-ISA; 3,5 diiodosalicylic acid, 3,5-di-ISA; 2-iodobenzoic acid, 2-IBeA; 4-iodobenzoic acid, 4-IBeA) compounds on tomato plants at an early stage of vegetative growth. As many organoiodine compounds are derived from salicylic (SA) and benzoic acids (BeA), treatments with I, SA and BeA in various treatments were realized and the influence of tested compounds on plant growth was analyzed. Iodine content was measured, as well as expression of key genes involved in I and SA metabolism. Organoiodine compounds accumulated mainly in roots whereas iodine accumulated in the upper parts when given as KI. The shoot system had 5, 12 and 25 times higher iodine content after KI treatment than after 4-IBeA, 5-ISA and 2-IBeA, or 3,5 diISA treatments, respectively. A toxic effect on plants was observed only for 3,5-diISA and 4-IBeA. The expression levels of a gene related to iodine metabolism (HMT, halide ion methylotransferase), a gene responsible for SA methylation in leaves (SAMT) and a gene related to SA catabolism (S3H, salicylic acid 3-hydroxylase) were modified differently depending on the iodine source. Overall, our data point out to a difference in plant uptake, transport of iodine in tomato plants based on the form of iodine compound. PMID- 29572861 TI - Expression of tenascin-C in a rat vocal fold injury model and its regulation of fibroblasts. AB - OBJECTIVES/HYPOTHESIS: Tenascin-C (Tnc) is an extracellular matrix (ECM) glycoprotein that plays a vital role in wound healing and fibrotic disease. Tnc is highly upregulated soon after vocal fold injury, but its function in the vocal fold has not yet been defined. In this study, we investigated Tnc expression in a rat vocal fold injury model in vivo and its roles in fibroblasts in vitro. STUDY DESIGN: In vivo and in vitro. METHODS: Tnc mRNA and protein expression levels were quantified on days 3, 7, 14, 28, and 56 after vocal fold injury in Sprague Dawley rats. In vitro, immunocytochemistry, Western blot, and quantitative real time polymerase chain reaction (qRT-PCR) analyses were performed in primary rat vocal fold fibroblasts following Tnc or transforming growth factor (TGF)-beta1 stimulation to investigate the phenotypic effects. RESULTS: Tnc mRNA and protein expression was upregulated dramatically on days 3 and 7 after injury, and significant differences were observed by qRT-PCR (P < .01). In vitro, Tnc significantly stimulated the migration of primary vocal fold fibroblasts. Following incubation with Tnc for 72 hours, alpha-smooth muscle actin, collagen I, and fibronectin expression was significantly upregulated (P < .05). TGF-beta1 increased Tnc expression in a time-dependent manner, and a mothers against decapentaplegic homolog 3 (SMAD3) inhibitor attenuated this TGF-beta1-induced stimulation. CONCLUSIONS: Tnc was highly upregulated during the early postinjury period in vivo and promoted vocal fold fibroblast migration, transdifferentiation, and ECM protein synthesis in vitro. Tnc was induced by TGF beta1 in a SMAD3-dependent manner. Transient expression of Tnc is likely to promote regeneration, but its potential role in fibrosis requires further study.

PMID- 29572863 TI - Enantioselective capillary electrophoresis provides insight into the phase II metabolism of ketamine and its metabolites in vivo and in vitro. AB - Glucuronidation catalyzed by uridine-5'-diphospho-glucuronosyl-transferases (UGTs) is the most important reaction in phase II metabolism of drugs and other compounds. O-glucuronidation is more common than N-glucuronidation. The anesthetic, analgesic and antidepressive drug ketamine is metabolized in phase I by cytochrome P450 enzymes to norketamine, hydroxynorketamine (HNK) diastereomers and dehydronorketamine (DHNK). Equine urine samples collected two hours after ketamine injection were treated with beta-glucuronidase and analyzed with three enantioselective capillary electrophoresis assays. Concentrations of HNK diastereomers and norketamine were significantly higher in comparison to untreated urine and an increase of ketamine and DHNK levels was found in selected but not all samples. This suggests that O-glucuronides of HNK and N-glucuronides of the other compounds are formed in equines. N-glucuronidation of norketamine was studied in vitro with liver microsomes of different species and the single human enzyme UGT1A4. With equine liver microsomes (ELM) a stereoselective N glucuronidation of norketamine was found that compares well to the results obtained with urines collected after ketamine administration. No reaction was observed with canine liver microsomes, human liver microsomes and UGT1A4. Incubation of ketamine and DHNK with ELM did not reveal any glucuronidation. Enantioselective CE is suitable to provide insight into the phase II metabolism of ketamine and its metabolites. PMID- 29572862 TI - Detection, characterization, and enrollment of donors of Ebola convalescent plasma in Sierra Leone. AB - BACKGROUND: Passive therapy with convalescent plasma provides an early opportunity to intervene in Ebola virus disease (EVD). Methods for field screening and selection of potential donors and quantifying plasma antibody are needed. STUDY DESIGN AND METHODS: Recombinant Ebola virus glycoprotein (EBOV GP) was formatted into immunoglobulin G-capture, competitive, and double-antigen bridging enzyme immunoassays (EIAs). EVD survivors in Freetown, Sierra Leone, were recruited as potential plasma donors and assessed locally using sera alone and/or paired sera and oral fluids (ORFs). Uninfected controls comprised unexposed Gambians and communities in Western Area, Sierra Leone. Antibody neutralization in selected sera was measured retrospectively in a pseudotype virus assay. RESULTS: A total of 115 potential donors were considered for enrollment: 110 plasma samples were concordantly reactive in the three EIAs; three were concordantly unreactive and two were reactive in two of three EIAs (98.2% agreement; 95% confidence interval [CI], 93.9%-99.8%). In 88 donors with paired ORF and plasma, G-capture EIA reactivity correlated well in the two analytes (R2 = 0.795). Plasma and ORF from 44 Gambians were unreactive. ORF samples from 338 of 339 unexposed Western Area community controls were unreactive (specificity, 99.7%; 95% CI, 98.4%-99.7%); ORF samples from 113 of 116 Kerry Town EVD survivors were reactive (sensitivity, 97.4%; 95% CI, 92.5%-99.5%). Strong reactivity in G-capture and/or competitive EIAs identified donors with high plasma EBOV GP antibody levels in the double-antigen bridging assay, correlating with high levels of neutralizing antibody. CONCLUSIONS: In-field testing can qualify convalescent donors for providing high-titer antibody. PMID- 29572864 TI - Genome editing in potato via CRISPR-Cas9 ribonucleoprotein delivery. AB - Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein-9 (CRISPR-Cas9) can be used as an efficient tool for genome editing in potato (Solanum tuberosum). From both a scientific and a regulatory perspective, it is beneficial if integration of DNA in the potato genome is avoided. We have implemented a DNA-free genome editing method, using delivery of CRISPR-Cas9 ribonucleoproteins (RNPs) to potato protoplasts, by targeting the gene encoding a granule bound starch synthase (GBSS, EC 2.4.1.242). The RNP method was directly implemented using previously developed protoplast isolation, transfection and regeneration protocols without further adjustments. Cas9 protein was preassembled with RNA produced either synthetically or by in vitro transcription. RNP with synthetically produced RNA (cr-RNP) induced mutations, i.e. indels, at a frequency of up to 9%, with all mutated lines being transgene-free. A mutagenesis frequency of 25% of all regenerated shoots was found when using RNP with in vitro transcriptionally produced RNA (IVT-RNP). However, more than 80% of the shoots with confirmed mutations had unintended inserts in the cut site, which was in the same range as when using DNA delivery. The inserts originated both from DNA template remnants from the in vitro transcription, and from chromosomal potato DNA. In 2-3% of the regenerated shoots from the RNP-experiments, mutations were induced in all four alleles resulting in a complete knockout of the GBSS enzyme function.

AB - We introduce TopoMS, a computational tool enabling detailed topological analysis of molecular and condensed-matter systems, including the computation of atomic volumes and charges through the quantum theory of atoms in molecules, as well as the complete molecular graph. With roots in techniques from computational topology, and using a shared-memory parallel approach, TopoMS provides scalable, numerically robust, and topologically consistent analysis. TopoMS can be used as a command-line tool or with a GUI (graphical user interface), where the latter also enables an interactive exploration of the molecular graph. This paper presents algorithmic details of TopoMS and compares it with state-of-the-art tools: Bader charge analysis v1.0 (Arnaldsson et al., 01/11/17) and molecular graph extraction using Critic2 (Otero-de-la-Roza et al., Comput. Phys. Commun. 2014, 185, 1007). TopoMS not only combines the functionality of these individual codes but also demonstrates up to 4* performance gain on a standard laptop, faster convergence to fine-grid solution, robustness against lattice bias, and topological consistency.

AB - OBJECTIVE: To investigate the clinical and surgical outcome correlates of preoperative hippocampal subfield volumes in patients with refractory temporal lobe epilepsy (TLE) using a new magnetic resonance imaging (MRI) multisequence segmentation technique. METHODS: We recruited 106 patients with TLE and hippocampal sclerosis (HS) who underwent conventional T1-weighted and T2 short TI inversion recovery MRI. An automated hippocampal segmentation algorithm was used to identify twelve subfields in each hippocampus. A total of 76 patients underwent amygdalohippocampectomy and postoperative seizure outcome assessment using the standardized ILAE classification. Semiquantitative hippocampal internal architecture (HIA) ratings were correlated with hippocampal subfield volumes. RESULTS: Patients with left TLE had smaller volumes of the contralateral presubiculum and hippocampus-amygdala transition area compared to those with right TLE. Patients with right TLE had reduced contralateral hippocampal tail volumes and improved outcomes. In all patients, there were no significant relationships between hippocampal subfield volumes and clinical variables such as duration and age at onset of epilepsy. There were no significant differences in any hippocampal subfield volumes between patients who were rendered seizure free and those with persistent postoperative seizure symptoms. Ipsilateral but not contralateral HIA ratings were significantly correlated with gross hippocampal and subfield volumes. CONCLUSIONS: Our results suggest that ipsilateral hippocampal subfield volumes are not related to the chronicity/severity of TLE. We did not find any hippocampal subfield volume or HIA rating differences in patients with optimal and unfavorable outcomes. In patients with TLE and HS, sophisticated analysis of hippocampal architecture on MRI may have limited value for prediction of postoperative outcome.

AB - INTRODUCTION: Children born after assisted reproductive technology, particularly singletons, have been shown to have an increased risk of congenital malformations compared with children born after spontaneous conception. We wished to study whether there has been a change in the past 20 years in the risk of major congenital malformations in children conceived after assisted reproductive technology compared with children spontaneously conceived. MATERIAL AND METHODS: Population-based cohort study including 90 201 assisted reproductive technology children and 482 552 children spontaneously conceived, born in Denmark, Finland, Norway and Sweden. Both singletons and twins born after in vitro fertilization, intracytoplasmatic sperm injection and frozen embryo transfer were included. Data on children were taken from when the national Nordic assisted reproductive technology registries were established until 2007. Multiple logistic regression analyses were used to estimate the risks and adjusted odds ratios for congenital malformations in four time periods: 1988-1992, 1993-1997, 1998-2002 and 2003 2007. Only major malformations were included. RESULTS: The absolute risk for singletons of being born with a major malformation was 3.4% among assisted reproductive technology children vs. 2.9% among children spontaneously conceived during the study period. The relative risk of being born with a major congenital malformation between all assisted reproductive technology children and children spontaneously conceived remained similar through all four time periods (p = 0.39). However, we found that over time the number of children diagnosed with a major malformation increased in both groups across all four time periods. CONCLUSION: When comparing children conceived after assisted reproductive technology and spontaneously conceived, the relative risk of being born with a major congenital malformation did not change during the study period.

In this study, we investigated the effect of AP on sciatic nerve denervation-induced muscle atrophy. METHODS: Sciatic nerve-denervated mice were fed a 0.1% AP-containing diet for 2 weeks. Muscle weight and cross-sectional area (CSA), and the expression of atrophic genes and inflammatory cytokines in the gastrocnemius were analyzed. RESULTS: Denervation significantly induced muscle atrophy. However, values for muscle weight and CSA were greater in the denervated muscle of the AP mice than the controls. AP suppressed the expression of MuRF1, but upregulated both myosin heavy chain (MHC) and MHC type IIb. AP also significantly suppressed expression of tumor necrosis-alpha in the gastrocnemius and soleus muscles, and interleukin-6 expression in the soleus muscle. DISCUSSION: AP appears to inhibit denervation-induced muscle atrophy, which may be due in part to its inhibitory effect on inflammatory processes within muscle. Muscle Nerve 58: 314-318, 2018. PMID- 29572869 TI - A new approach to assess the effect of photodamage on corneocyte envelope maturity using combined hydrophobicity and mechanical fragility assays. AB - BACKGROUND: The maturity of the corneocyte envelope (CE) provides information about the barrier functionality of the stratum corneum (SC). Corneocytes are enclosed by the CE, a protein-lipid matrix, contributing to mechanical resistance and hydrophobicity of the SC. OBJECTIVES: The aim of the work was to develop a novel and robust approach to characterize CE maturity based on rigidity, hydrophobicity and surface area. This offers an alternative approach to the Nile red staining and antigenicity of involucrin to characterize the CE. The photoexposed (PE) cheek and photoprotected (PP) post-auricular sites were selected for investigation. METHODS: Nine tape strips were obtained from the cheek and post-auricular sites of healthy Caucasians. CEs on the first and last tape strip were subjected to sonication to assess rigidity, and Nile red staining to determine hydrophobicity per unit surface area. In addition, the presence of involucrin and lipids was assessed to determine CE maturity by examination of the red/green pixel ratio, percentage of involucrin expressing CEs and alternatively the ratio of fluorescence density. RESULTS: The CE rigidity was lower in the deeper SC layers of the cheek, whereas post-auricular CEs were mechanically more resistant. Post-auricular CEs from the superficial SC had a larger surface area with a stronger fluorescence signal than those from the cheek. Interestingly, those CEs from the deeper SC layers had similar surface areas in both anatomical sites but were significantly different in hydrophobicity. These three parameters can be summarized as a relative CE maturity index that expresses CE maturity more precisely with a higher sensitivity than the conventional involucrin and Nile red staining approach. CEs of the cheek surface are more mature than CEs in the deeper SC layer, whereas CEs obtained from the post-auricular surface are more mature than those from the cheek surface. CONCLUSION: The combined method developed allows characterization of CE maturity based on hydrophobicity per unit surface area and rigidity rather than a simple ratio of lipid to involucrin. A more robust and sensitive measurement has therefore been developed addressing the limitations of earlier protocols. PMID- 29572870 TI - Omics approaches for food authentication. AB - The development of analytical strategies to fight against food fraud is currently one of the most developing fields in food science as the food value chain becomes increasingly complex and global. Food can be certified by clear labeling but also by objective analytical methods. As shown recently by several groups, the omics technologies such as genomics, proteomics, metabolomics, and isotopolomics are suitable to prove the geographical origin, the production or cultivation process, and the biological and the overall chemical identity of food. This article describes different analytical approaches beginning with non-targeted strategies as well as the further developmental stages of transferring the methods to routine laboratories. PMID- 29572871 TI - A preliminary origin-tracking study of different densities urinary exosomes. AB - Based on density differences of different subpopulations of exosomes, two kinds of micro-vesicles with different densities were captured from urine by a modified sucrose density gradient ultracentrifuge separation method. Verified by transmission electron microscope (TEM) and western blot, the results showed these two kinds of micro-vesicles were all exosomes. And these two kinds of exosomes were analyzed by TEM, 2D electrophoresis (2DE), and capillary zone electrophoresis (CZE), respectively. The results of TEM showed these two exosomes with different densities have different morphological characteristics, and some tiny proteomic differences were shown in the results of 2DE of these two exosomes. At the same time, the CZE results displayed these two kinds of exosomes possessed different retention times, indicated that they may have different electrification property and particle weight. These results may attribute to their different origins. This work may provide a preliminary experience for the origin-tracking study for urinary exosomes, and would be more useful for future targeted biomarker discovery. PMID- 29572872 TI - Differential transcriptome analysis of zebrafish (Danio rerio) larvae challenged by Vibrio parahaemolyticus. AB - Zebrafish embryo and larva represent a useful in vivo model for identification of host innate immune responses to bacterial infection. Vibrio parahaemolyticus is a typical zoonotic pathogen worldwide that causes acute gastroenteritis in humans and vibriosis in fishes. However, the mechanism of the innate immune response in the zebrafish larvae infected by V. parahaemolyticus has not been clear. We analysed the transcriptomic profile of 3 days post-fertilization (dpf) zebrafish larvae immersed in V. parahaemolyticus 13 (Vp13) strain suspension for 2 hr. A total of 602 differentially expressed genes (DEGs) were identified in the infection group, of which 175 (29.07%) genes were upregulated and 427 (70.93%) genes were downregulated. These altered genes encoded complement and coagulation cascades, chemokine, TNF signalling pathway, NF-kappaB signalling pathway and JAK STAT signalling pathway. Some significant DEGs, such as mmp13, cxcr4a, ccl20, hsp70, gngt, serpina1l, il8, cofilin and il11, were subjected to quantitative gene expression analysis, and the results were consistent with those of the transcriptome profile. These results clearly demonstrated that exposure to V. parahaemolyticus for 2 hr could activate innate immune response in 3dpf larvae by altered expression of downstream signalling pathway genes of pattern recognition receptors (PRRs). Our results also provide a useful reference for future analysis of signal transduction pathways and pathogenesis mechanisms underlying the systemic innate immune response to the external bacteria of V. parahaemolyticus.

AB - OBJECTIVE: To evaluate cardiac function by conventional echocardiography and tissue Doppler imaging in fetuses with left congenital diaphragmatic hernia (CDH). METHODS: Conventional echocardiography (myocardial performance index, ventricular filling velocities, and E/A ratios) and tissue Doppler imaging (annular myocardial peak velocities, E/E' and E'/A' ratios) in mitral, septal, and tricuspid annulus were evaluated in a cohort of 31 left-sided CDH fetuses and compared with 75 controls matched for gestational age 2:1. RESULTS: In comparison to controls, CDH fetuses had prolonged isovolumetric time periods (isovolumetric contraction time 35 ms vs 28 ms, P < .001), with higher myocardial performance index (0.49 vs 0.42, P < .001) and tricuspid E/A ratios (0.77 vs 0.72, P = .033). Longitudinal function assessed by tissue Doppler showed signs of impaired relaxation (mitral lateral A' 8.0 vs 10.1 cm/s, P < .001 and an increased mitral lateral E'/A' ratio 0.93 vs 0.78, P < .001) in the CDH fetuses as compared with controls, with preserved systolic function. CONCLUSION: Left CDH fetuses show echocardiographic signs of diastolic dysfunction, probably secondary to fetal heart compression, maintaining a preserved systolic function.

AB - Rising interest in ellagic acid (EA) present in functional foods is supported by its antimutagenic, anticarcinogenic, antiviral, antibacterial and antioxidative effects. The present approach presents for the first time the determination of ellagic acid and other phenolics in wines by miniaturized solid phase extraction prior to capillary zone electrophoresis (CZE) with UV. The extraction was performed using a home-made miniaturized pipette tip column. The procedure allowed a significant reduction in conditioning/sample/washing/elution volumes. The effects of important factors affecting the extraction efficiency as well as electrophoretic performance were investigated to acquire optimum conditions. The analytes were separated within 10 min with a BGE containing 30 mmol/L sodium tetraborate 10% v/v MeOH pH 9.10. The optimized method was applied to the determination of ellagic acid in commercial and pilot-scale wines. Indeed, the content of EA was correlated with viticultural parameters such as grape varietal, production area, and aging conditions (oak wood guard and glass bottle ward). In order to validate the results, a comparison between the CZE and HPLC data was made. PMID- 29572875 TI - Unmasking the silent motor neuron loss in amyotrophic lateral sclerosis.

AB - Three fractions (I-III) were separated from crude oligosaccharides of lotus seeds by fast protein liquid chromatography with final purity of 97.6, 96.3, and 96.8%, respectively. The fractions were identified as sucrose, raffinose, and stachyose by using TLC, HPLC with charged aerosol detector (CAD), LC-MS, and methylation analysis. Subsequently sucrose and raffinose family oligosaccharides (RFOs) with degree of polymerization (DP) 3-5 (raffinose, stachyose, and verbascose) have been quantified by HPLC-CAD for the first time. All calibration curves for investigated analytes showed good linear regression (R2 > 0.9952). Their limit of detection and limit of quantity were in the ranges 0.14-0.28 and 0.36-0.48 MUg/mL, respectively. The recoveries ranged from 96.6 to 103.4%. The contents of sucrose and RFOs DP3-DP5 were different in lotus seeds and other parts of lotus samples, but similar in their own variety. Additionally, the distribution of RFOs in different parts of lotus were also compared and the results indicated that RFOs might be mainly synthesized in lotus seeds. This work is helpful for understanding the way of biosynthesis of RFOs in lotus as well as quality control of plants containing RFOs. PMID- 29572876 TI - Research advances based on mass spectrometry for profiling of triacylglycerols in oils and fats and their applications. AB - Vegetable oils and animal fats are dietary source of lipids that play critical and multiple roles in biological function. Triacylglycerols (TAGs) are the principal component of oils and fats with significant difference in profile among different oils and fats. TAG profiling is essential for nutritional evaluation, quality control and assurance of safety in oils and fats. However, analysis of TAGs is a challenging task because of the complicated composition of TAGs and their similar physicochemical properties in oils and fats. The rapid development of mass spectrometry (MS) technology in recent years makes it possible to analyze the composition, content and structure of TAGs in the study of the physical, chemical and nutritional properties of oils, fats and related products. This review described the research advancement based on MS for profiling of TAGs in oil, fat and their applications in food. The application of MS, including direct infusion strategies, and its combination with chromatography, gas chromatography MS (GC-MS) and liquid chromatography-MS (LC-MS), in the analysis of TAGs were reviewed. The advantages and disadvantages of these analytical methods with relevant applications for TAGs analysis in food were also described. PMID- 29572878 TI - Muscle contractures in patients with cerebral palsy and acquired brain injury are associated with extracellular matrix expansion, pro-inflammatory gene expression, and reduced rRNA synthesis. AB - INTRODUCTION: Children with cerebral palsy (CP) and acquired brain injury (ABI) commonly develop muscle contractures with advancing age. An underlying growth defect contributing to skeletal muscle contracture formation in CP/ABI has been suggested. METHODS: The biceps muscles of children and adolescents with CP/ABI (n = 20) and typically developing controls (n = 10) were investigated. We used immunohistochemistry, quantitative real-time polymerase chain reaction, and Western blotting to assess gene expression relevant to growth and size homeostasis. RESULTS: Classical pro-inflammatory cytokines and genes involved in extracellular matrix (ECM) production were elevated in skeletal muscle of children with CP/ABI. Intramuscular collagen content was increased and satellite cell number decreased and this was associated with reduced levels of RNA polymerase I transcription factors, 45s pre-rRNA and 28S rRNA. DISCUSSION: The present study provides novel data suggesting a role for pro-inflammatory cytokines and reduced ribosomal production in the development/maintenance of muscle contractures, possibly underlying stunted growth and perimysial ECM expansion.

AB - Clinical success of pediatric veno-venous (VV) extracorporeal membrane oxygenation (ECMO) is associated with the double lumen cannula cardiovascular device design as well as its anatomic orientation in the atrium. The positions of cannula ports with respect to the vena cavae and the tricuspid valve are believed to play a significant role on device hemodynamics. Despite various improvements in ECMO catheters, especially for the neonatal and congenital heart patients, it is still challenging to select a catalogue size that would fit to most patients optimally. In effect, the local unfavorable blood flow characteristics of the cannula would translate to an overall loss of efficiency of the ECMO circuit. In this study, the complex flow regime of a neonatal double lumen cannula, positioned in a patient-specific right atrium, is presented for the first time in literature. A pulsatile computational fluid dynamics (CFD) solver that is validated for cardiovascular device flow regimes was used to perform the detailed flow, oxygenated blood transport, and site-specific blood damage analysis using an integrated cannula and right atrium model. A standard 13Fr double lumen cannula was scanned using micro-CT, reconstructed and simulated under physiologic flow conditions. User defined scalar transport equations allowed the quantification of the mixing and convection of oxygenated and deoxygenated blood as well as blood residence times and hemolysis build-up. Site-specific CFD analysis provided key insight into the hemodynamic challenges encountered in cannula design and the associated intra-atrial flow patterns. Due to neonatal flow conditions, an ultra high velocity infusion jet emanated from the infusion port and created a zone of major recirculation in the atrium. This flow regime influenced the delivery of the oxygenated blood to the tricuspid valve. Elevated velocities and complex gradients resulted in higher wall shear stresses (WSS) particularly at the infusion port having the highest value followed by the aspiration hole closest to the drainage port. Our results show that, in a cannula that is perfectly oriented in the atrium, almost 38% of the oxygenated blood is lost to the atrial circulation while only half of the blood from inferior vena cava (IVC) can reach to the tricuspid valve. As such, approximately 6% of venous blood from superior vena cava (SVC) can be delivered to tricuspid. High values of hemolysis index were observed with blood damage encountered around infusion hole (0.025%). These results warrant further improvements in the cannula design to achieve optimal performance of ECMO and better patient outcomes. PMID- 29572880 TI - Postoperative ergometry-guided programming does not prevent T-wave oversensing and inappropriate shocks in S-ICD patients. AB - BACKGROUND: T-wave oversensing (TWOS) is a feared complication after subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation, potentially leading to inappropriate shocks (IS) with tremendous impact on quality of life. HYPOTHESIS: Postoperative ergometry facilitates primary and secondary prevention of TWOS or other potential causes of IS and optimizes S-ICD programming. METHODS: We analyze the impact of ergometry guided-programming (EMGP) on primary and secondary prevention of TWOS/IS in S-ICD patients, we screened 146 patients implanted in our center (2010-2016) for the incidence of TWOS/IS during postoperative ergometry. Furthermore, to evaluate the outcome in 123 eligible patients complete follow-up (FU) of at least 6 months up to 2 years was retrospectively analyzed. RESULTS: (1) Primary prevention: TWOS could only be provoked postoperatively in 3.7% of patients (n = 3/82). FU analyses did not reveal significant differences compared to our control group (Ctrl: n = 6/61, 9.8% vs EMGP: n = 5/62, 8.1%; P = 0.731). Further subgroup analyses of patients with postoperative ergometry in the close postoperative period (< 7 days; n = 3/45, 6.7%; P = 0.563) did not yield any significant difference. (2) Secondary prevention: We found various causes of TWOS/IS. In patients who underwent reprogramming due to previous TWOS/IS events we observed a 66.7% (n = 6/9) reduction of TWOS/IS using EMGP. CONCLUSION: TWOS/IS has various causes while not all cases are exercise-associated. Postoperative ergometry does not seem to be useful for primary prevention. Further trials need to investigate the potential benefit of EMGP for secondary prevention of TWOS/IS. PMID- 29572881 TI - Day-case device implantation-A prospective single-center experience including patient satisfaction data. AB - PURPOSE: Many centers perform day-case cardiac rhythm management (CRM) device implantation. However, there is a paucity of prospective data concerning this approach. We performed a prospective single-center study of day-case device implantation, including data on patient satisfaction. METHODS: All patients scheduled for a new elective device were considered for a day-case procedure. Exclusion criteria were living alone or without a suitable carer, advancing age/frailty, a metallic valve, and persistent complete heart block. Following discharge, patients were reviewed in device clinic at 6 weeks with an anonymized questionnaire. RESULTS: During the study period (May 2014-August 2016), 797 new CRM devices were implanted. Of these, 232 were elective and included in the analysis; 101 were planned to be day-case and 131 scheduled for overnight stay. Of the 101 day-case patients, 52 had a pacemaker, 28 an implantable cardioverter defibrillator (ICD), 16 a cardiac resynchronization therapy pacemaker/defibrillator, and five a subcutaneous-ICD. Complications were similar in the day-case (n = 12, 12%) and overnight stay (n = 15, 11%) groups (P = 0.92). In the day-case group, 93 (92%) patients went home the same day. An estimated 111 overnight bed days were saved, translating to a cost saving of L61,912 (euro 70,767, $79,211). Note that 99% (n = 100) of patients returned the questionnaire. Patient satisfaction was universally high. The majority (n = 98, 98%) felt ready to go home on discharge; only a minority (n = 5, 5%) would have preferred an overnight stay. CONCLUSIONS: A significant proportion of elective new CRM device implants can be performed as day-case procedures. With appropriate selection patient acceptability of same-day discharge is high.

AB - BACKGROUND: Associations between irritable bowel syndrome and other health problems have been described, but comprehensive reports are missing, especially in primary care. AIMS: To investigate which health problems are associated with irritable bowel syndrome, how they cluster together and when they are typically diagnosed relative to irritable bowel syndrome. METHODS: We used Intego, a general practice registry in Flanders, Belgium. Patients with an irritable bowel syndrome diagnosis (n = 13 701) were matched with controls without gastrointestinal diagnosis and controls with organic gastrointestinal disease. Long-term prevalences of 680 symptoms and diagnoses were compared between patients and controls. Results were summarised using functional enrichment analysis and visualised in a network and we calculated incidence rate ratios in the 10 years before and after the irritable bowel syndrome diagnosis for the network's key components. RESULTS: Various symptoms and infections, but not neoplasms, were enriched in irritable bowel syndrome patients compared to both control groups. We characterised the comorbidities of irritable bowel syndrome as psychosocial health problems, urogenital symptoms and infections, musculoskeletal symptoms and other somatic symptoms. These had a uniform incidence in the years around the irritable bowel syndrome diagnosis, and did not structurally precede or follow irritable bowel syndrome. CONCLUSIONS: Irritable bowel syndrome shares long-term associations with psychosocial health problems, urogenital symptoms and infections, musculoskeletal symptoms and other somatic symptoms in primary care. Clinicians are encouraged to take comorbidities into account when diagnosing and managing irritable bowel syndrome, as this may have important treatment implications. PMID- 29572887 TI - Fibromyalgia syndrome and small fiber, early or mild sensory polyneuropathy. AB - INTRODUCTION: Pain mechanisms in fibromyalgia syndrome (FMS) are not clearly understood. Growing evidence appears to suggest a role for small fiber polyneuropathy (SFPN) in some FMS patients, as measured by epidermal nerve fiber density (ENFD). We aimed to better characterize and distinguish the subset of patients with both fibromyalgia and small fiber, early or mild sensory polyneuropathy (FM-SFSPN). METHODS: 155 FMS patients with neuropathic symptoms completed a Short Form McGill Questionnaire and visual analog scale in addition to having skin biopsies, nerve conduction studies (NCS), and serologic testing. RESULTS: Sural and medial plantar (MP) response amplitudes correlated with ENFD, with markers of metabolic syndrome being more prevalent in this subset of patients. Pain intensity and quality did not distinguish patients. DISCUSSION: The FM-SFSPN subset of patients may be identified through sural and MP sensory NCS and/or skin biopsy but cannot be identified by pain features and intensity.

AB - OBJECTIVES: Distortions in autobiographical memory have been implicated in major depressive disorder (MDD). Those with MDD demonstrate a 'depressogenic' autobiographical life structure. Research has not examined how culture influences this process. We investigated whether Malay individuals (members of an interdependent culture) with MDD demonstrated a 'depressogenic' autobiographical life structure similar to that of British individuals (members of an independent culture) with MDD. DESIGN: A 2 (Culture; Malay, British) * 2 (Mood; depressed, control) cross-sectional design using a card sort task and self-report measures was used. METHODS: Malay individuals with MDD or no history of MDD completed the life-structure card-sorting task, which provided a novel method for investigating organizational structure of the life narrative. These data were compared to previously collected data in which British individuals with MDD or without MDD had completed the same task within the same experimental protocol. RESULTS: Pan culturally those with MDD had greater negativity (i.e., used more negative attributes), negative redundancy (i.e., used the same negative attributes repeatedly across life chapters) and negative emodiversity (i.e., had greater variety and relative abundance of negative attributes), and reduced positive redundancy (i.e., used the same positive attributes repeatedly across chapters) in their structuring relative to controls. While the British MDD group had greater compartmentalization (i.e., the negative and positive attributes were clustered separately across different chapters) than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls. CONCLUSIONS: The findings suggest culture may shape aspects of the autobiographical life structure in MDD. PRACTITIONER POINTS: The majority of the literature investigating depression pertains to individuals from European Western cultures, despite recognition that depression ranks as one of the most debilitating diseases worldwide. This raises questions as to whether current depression models and interventions can be applied universally or whether they are limited to European Western groups. The current study found that pan culturally those with MDD had similar structuring of their life story relative to controls. However, there were some cultural differences that need to be considered (e.g., Malay individuals provided less detailed, less elaborate and less emotionally diverse life stories and while the British MDD group had greater compartmentalization than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls). Limitations of the study included group differences in gender and mood at the time of testing. Cultural differences in the number of attributes used may have influenced findings. Only the Malay group completed the individualism-collectivism measure. PMID- 29572888 TI - PRDM8 exhibits antitumor activities toward hepatocellular carcinoma by targeting NAP1L1. AB - : Hepatocellular carcinoma (HCC) is a major leading cause of cancer mortality worldwide. PRDI-BF1 and RIZ homology domain containing 8 (PRDM8) is a key regulator in neural development and testis steroidogenesis; however, its role in liver carcinogenesis remains to be investigated. In this study, PRDM8 was found to be down-regulated in HCC, which was linked with shorter recurrence-free survival. Lentiviral-based overexpression and knockdown approaches showed that PRDM8 inhibited HCC cell proliferation, migration, and invasion. PRDM8 caused G1/S cell cycle arrest and induced apoptosis. An in vivo tumor model confirmed the antitumor role of PRDM8 in HCC growth and metastasis. Mechanistic study showed that PRDM8 suppressed the PI3K/AKT/mTOR signaling cascade through the regulation of nucleosome assembly protein 1-like 1 (NAP1L1). CONCLUSION: PRDM8 as a functional tumor suppressor is frequently down-regulated in HCC. Through regulating NAP1L1, PRDM8 inhibits PI3K/AKT/mTOR signaling in HCC. PRDM8 is a potential target for novel therapies of HCC. (Hepatology 2018). PMID- 29572889 TI - Risk factors for diagnostic delay in Crohn's disease and their impact on long term complications: how do they differ in a tuberculosis endemic region? AB - BACKGROUND: The diagnosis of Crohn's disease (CD) can be delayed in clinical practice. In tuberculosis endemic areas, empirical anti-tubercular therapy further delays treatment. AIM(S): To assess risk factors for diagnostic delay and its impact on the long-term complications of Crohn's disease in India where tuberculosis is endemic. METHODS: Data from a large prospectively established inflammatory bowel disease registry were analysed retrospectively. The time from onset of symptoms to diagnosis (diagnostic delay) was calculated and categorised into two groups based on median diagnostic delay. The risk factors for delay including anti-tubercular therapy were analysed. Logistic regression analysis was done to assess impact of diagnostic delay on development of stenotic and fistular complications including need for surgery. RESULTS: Seven hundred and twenty Crohn's disease patients (60.3% male, median: 28 years) were included. Main outcome measures were stenosis, fistula and need for surgery. Subjects with diagnostic delay >18 months (median) developed significantly higher stenotic complications and surgery (OR 4.12; 95% CI: 2.74-6.33, P < 0.001 and OR 2.41, 95% CI: 1.68-3.42, P < 0.001), respectively, compared to those <=18 months. There was no difference in the development of fistulous complications. 193/720 (27%) received anti-tubercular therapy which significantly contributed to diagnostic delay (OR: 2.47; 95% CI: 1.76-3.47, P < 0.001) with 47% showing initial clinical response (Crohn's disease activity index- CDAI decrease >100). Moreover, the incidence of stenotic complications was significantly higher in patients who had received prior anti-tubercular therapy (55/193 (28.49%) vs 78/527 (14.8%), P < 0.001, OR: 2.60, 95% CI: 1.64-4.12). CONCLUSIONS: Diagnostic delay in Crohn's disease is associated with significantly higher stenotic complications and need for surgery. Empirical anti-tubercular therapy is the single largest contributor to diagnostic delay in tuberculosis endemic areas. Despite initial clinical response to anti-tubercular therapy, long-term stenotic complications are higher. PMID- 29572890 TI - A general approach to evaluating the bias of 2-stage instrumental variable estimators. AB - Unmeasured confounding is a common concern when researchers attempt to estimate a treatment effect using observational data or randomized studies with nonperfect compliance. To address this concern, instrumental variable methods, such as 2 stage predictor substitution (2SPS) and 2-stage residual inclusion (2SRI), have been widely adopted. In many clinical studies of binary and survival outcomes, 2SRI has been accepted as the method of choice over 2SPS, but a compelling theoretical rationale has not been postulated. We evaluate the bias and consistency in estimating the conditional treatment effect for both 2SPS and 2SRI when the outcome is binary, count, or time to event. We demonstrate analytically that the bias in 2SPS and 2SRI estimators can be reframed to mirror the problem of omitted variables in nonlinear models and that there is a direct relationship with the collapsibility of effect measures. In contrast to conclusions made by previous studies (Terza et al, 2008), we demonstrate that the consistency of 2SRI estimators only holds under the following conditions: (1) when the null hypothesis is true; (2) when the outcome model is collapsible; or (3) when estimating the nonnull causal effect from Cox or logistic regression models, the strong and unrealistic assumption that the effect of the unmeasured covariates on the treatment is proportional to their effect on the outcome needs to hold. We propose a novel dissimilarity metric to provide an intuitive explanation of the bias of 2SRI estimators in noncollapsible models and demonstrate that with increasing dissimilarity between the effects of the unmeasured covariates on the treatment versus outcome, the bias of 2SRI increases in magnitude. PMID- 29572891 TI - Link between gut-microbiome derived metabolite and shared gene-effects with hepatic steatosis and fibrosis in NAFLD. AB - : Previous studies have shown that gut-microbiome is associated with nonalcoholic fatty liver disease (NAFLD). We aimed to examine if serum metabolites, especially those derived from the gut-microbiome, have a shared gene-effect with hepatic steatosis and fibrosis. This is a cross-sectional analysis of a prospective discovery cohort including 156 well-characterized twins and families with untargeted metabolome profiling assessment. Hepatic steatosis was assessed using magnetic-resonance-imaging proton-density-fat-fraction (MRI-PDFF) and fibrosis using MR-elastography (MRE). A twin additive genetics and unique environment effects (AE) model was used to estimate the shared gene-effect between metabolites and hepatic steatosis and fibrosis. The findings were validated in an independent prospective validation cohort of 156 participants with biopsy-proven NAFLD including shotgun metagenomics sequencing assessment in a subgroup of the cohort. In the discovery cohort, 56 metabolites including 6 microbial metabolites had a significant shared gene-effect with both hepatic steatosis and fibrosis after adjustment for age, sex and ethnicity. In the validation cohort, 6 metabolites were associated with advanced fibrosis. Among them, only one microbial metabolite, 3-(4-hydroxyphenyl)lactate, remained consistent and statistically significantly associated with liver fibrosis in the discovery and validation cohort (fold-change of higher-MRE versus lower-MRE: 1.78, P < 0.001 and of advanced versus no advanced fibrosis: 1.26, P = 0.037, respectively). The share genetic determination of 3-(4-hydroxyphenyl)lactate with hepatic steatosis was RG :0.57,95%CI:0.27-0.80, P < 0.001 and with fibrosis was RG :0.54,95%CI:0.036-1, P = 0.036. Pathway reconstruction linked 3-(4 hydroxyphenyl)lactate to several human gut-microbiome species. In the validation cohort, 3-(4-hydroxyphenyl)lactate was significantly correlated with the abundance of several gut-microbiome species, belonging only to Firmicutes, Bacteroidetes and Proteobacteria phyla, previously reported as associated with advanced fibrosis. CONCLUSION: This proof of concept study provides evidence of a link between the gut-microbiome and 3-(4-hydroxyphenyl)lactate that shares gene effect with hepatic steatosis and fibrosis.

AB - Cadmium (Cd) is a persistent environmental and occupational contaminant that accumulates in humans and shows adverse effects on health. Accumulating evidence reveals that environmental Cd exposure is associated with hepatic lipid accumulation and metabolic alterations in adult male mice. However, whether Cd exposure induces hepatic lipid accumulation and metabolic alterations in female mice remains poorly understood. In the present study, we aimed to investigate the effects of Cd exposure on insulin resistance, hepatic lipid accumulation and associated metabolic pathways. Female CD1 mice were administrated with CdCl2 (10 and 100 mg l-1 ) by drinking water. We found that Cd exposure did not induce obesity, insulin resistance and hepatic lipid accumulation. By contrary, mice in the Cd-100 mg l-1 group presented a significant reduction of the glucose area under the curve during the glucose tolerance test. However, there was a significant elevation in the mRNA level of Fasn and Scd-1, which were critical genes during hepatic fatty acid synthesis. Moreover, hepatic Fabp1 and Fabp4, two genes for hepatic fatty acid uptake were upregulated in Cd-treated mice. Of interest, Lpl, a key gene for hepatic lipoprotein lysis, was also upregulated in Cd-treated mice. Collectively, our results suggest that Cd exposure upregulated mRNA level of genes related to hepatic lipid metabolism although there was no insulin resistance and hepatic lipid accumulation shown in the present study. PMID- 29572892 TI - Sphingosine kinase 1 promotes liver fibrosis by preventing miR-19b-3p-mediated inhibition of CCR2. AB - : Chronic liver disease mediated by activation of hepatic stellate cells (HSCs) and Kupffer cells (KCs) leads to liver fibrosis. Here, we aimed to investigate the molecular mechanism and define the cell type involved in mediating the sphingosine kinase (SphK)1-dependent effect on liver fibrosis. The levels of expression and activity of SphK1 were significantly increased in fibrotic livers compared with the normal livers in human. SphK1 was coexpressed with a range of HSC/KC markers including desmin, alpha-smooth muscle actin (alpha-SMA) and F4/80 in fibrotic liver. Deficiency of SphK1 (SphK1-/- ) resulted in a marked amelioration of hepatic injury, including transaminase activities, histology, collagen deposition, alpha-SMA and inflammation, in CCl4 or bile duct ligation (BDL)-induced mice. Likewise, treatment with a specific inhibitor of SphK1, 5C, also significantly prevented liver injury and fibrosis in mice induced by CCl4 or BDL. In cellular levels, inhibition of SphK1 significantly blocked the activation and migration of HSCs and KCs. Moreover, SphK1 knockout in KCs reduced the secretion of CCL2, and SphK1 knockout in HSCs reduced C-C motif chemokine receptor 2 ([CCR2] CCL2 receptor) expression in HSCs. CCL2 in SphK1-/- mice was lower whereas microRNA-19b-3p in SphK1-/- mice was higher compared with wild-type (WT) mice. Furthermore, microRNA-19b-3p downregulated CCR2 in HSCs. The functional effect of SphK1 in HSCs on liver fibrosis was further strengthened by the results of animal experiments using a bone marrow transplantation (BMT) method. CONCLUSION: SphK1 has distinct roles in the activation of KCs and HSCs in liver fibrosis. Mechanistically, SphK1 in KCs mediates CCL2 secretion, and SphK1 in HSCs upregulates CCR2 by downregulation of miR-19b-3p. (Hepatology 2018).

AB - Among swine reproductive traits, sow lifetime productivity (SLP) is considered a profitable trait in commercial pig farming. Notably, longevity and efficiency in SLP can be adopted as the key phenotype representing SLP. In this study, we conducted a co-association network analysis using results from a genome-wide association study for SLP-related traits. A total of 656 purebred Landrace female pigs were genotyped using a 60K SNP array. Significantly associated SNPs identified from the GWAS were annotated for the specific genes. Then, we constructed an association weight matrix to build a network based on the co associations between the genes and 10 SLP traits. The entire network consisted of 495 nodes and 37 755 significant edges. We identified three key regulatory transcription factors: STAT2 (signal transducer and activator of transcription 2), MYF6 (myogenic factor 6) and TFCP2L1 (transcription factor CP2 like 1). The network revealed that the STAT2 and MYF6 regulatory modules cooperate with each other and specifically influence the longevity and efficiency of sows, whereas the TFCP2L1 family specifically affects the improvement of litter size. PMID- 29572896 TI - Argininosuccinate synthase 1 and periportal gene expression in sonic hedgehog hepatocellular adenomas. AB - : Genetic alterations define different molecular subclasses of hepatocellular adenoma (HCA) linked with risk factors, histology and clinical behavior. Recently, Argininosuccinate Synthase 1 (ASS1), a major periportal protein, was proposed as a marker of HCA with a high risk of hemorrhage. We aimed to assess the significance of ASS1 expression through the scope of the HCA molecular classification. ASS1 expression was evaluated using RNAseq, quantitative reverse transcriptase polymerase chain reaction (RT-PCR) and Immunohistochemistry. ASS1 and glioma-associated oncogene 1 (GLI1) expression were analyzed in vitro after modulation of GLI1 expression. Using RNAseq in 27 HCA and five nontumor liver samples, ASS1 expression was highly correlated with GLI1 expression (P<0.0001, R=0.75). In the overall series of 408 HCA, ASS1 overexpression was significantly associated with sonic hedgehog HCA (shHCA) compared to other molecular subgroups (P<0.0001), suggesting that sonic hedgehog signaling controls ASS1 expression. GLI1 expression silencing by siRNA induced a downregulation of ASS1 in PLC/PFR5 and SNU878 cell lines. In 390 HCA, we showed that ASS1 expression belonged to the periportal expression program that was maintained in shHCA but down-regulated in all the other HCA subtypes. In contrast, HCA with beta-catenin activation showed an activation of a perivenous program. Despite the significant association between GLI1 and ASS1 expression, ASS1 mRNA expression was not associated with specific clinical features. At the protein level using immunohistochemistry, prostaglandin D synthase (PTGDS) was strongly and specifically overexpressed in shHCA. CONCLUSION: ASS1 is associated with sonic hedgehog activation as part of a periportal program expressed in shHCA, a molecular subgroup defined by INHBE-GLI1 gene fusion. (Hepatology 2018). PMID- 29572898 TI - James Melius, our colleague and friend. PMID- 29572897 TI - Acute hepatitis B virus infection in humanized chimeric mice has multiphasic viral kinetics. AB - : Chimeric urokinase type plasminogen activator (uPA)/severely severe combined immunodeficiency (SCID) mice reconstituted with humanized livers are useful for studying hepatitis B virus (HBV) infection in the absence of an adaptive immune response. However, the detailed characterization of HBV infection kinetics necessary to enable in-depth mechanistic studies in this in vivo HBV infection model is lacking. To characterize HBV kinetics post-inoculation (p.i.) to steady state, 42 mice were inoculated with HBV. Serum HBV DNA was frequently measured from 1 minute to 63 days p.i. Total intrahepatic HBV DNA, HBV covalently closed circular DNA (cccDNA), and HBV RNA was measured in a subset of mice at 2, 4, 6, 10, and 13 weeks p.i. HBV half-life (t1/2 ) was estimated using a linear mixed effects model. During the first 6 hours p.i., serum HBV declined in repopulated uPA/SCID mice with a t1/2 = 62 minutes (95% confidence interval [CI] = 59-67). Thereafter, viral decline slowed followed by a 2-day lower plateau. Subsequent viral amplification was multiphasic with an initial mean doubling time of t2 = 8 +/- 3 hours followed by an interim plateau before prolonged amplification (t2 = 2 +/- 0.5 days) to a final HBV steady state of 9.3 +/- 0.3 log copies (cps)/mL. Serum HBV and intrahepatic HBV DNA were positively correlated (R2 = 0.98). CONCLUSION: HBV infection in uPA/SCID chimeric mice is highly dynamic despite the absence of an adaptive immune response. Serum HBV t1/2 in humanized uPA/SCID mice was estimated to be ~1 hour regardless of inoculum size. The HBV acute infection kinetics presented here is an important step in characterizing this experimental model system so that it can be effectively used to elucidate the dynamics of the HBV life cycle and thus possibly reveal effective antiviral drug targets.

PMID- 29572900 TI - High prevalence and familial aggregation of keratoconus in an Iranian rural population: a population-based study. AB - PURPOSE: The objective of this study was to determine the prevalence of keratoconus and the potential effect of genetic and environmental factors on its prevalence in households living in rural areas of Iran in a large population based study. METHODS: The present cross-sectional study was performed in two Iranian rural populations. Two rural areas were randomly selected in the southwest and north of Iran. All individuals over one year of age were invited to participate in the study. The study population underwent a thorough eye examination, including visual acuity measurement, refraction, slit lamp biomicroscopy, and Scheimpflug imaging. The diagnosis of keratoconus was made based on Pentacam-specific criteria, tomographic maps, and clinical findings. After detecting keratoconus cases, its prevalence in the study population was reported as a percentage with a 95% confidence interval (CI). For familial aggregation analysis, the odds ratios of keratoconus and its more severe types were calculated in different family relationships (siblings, parents-offspring, spouses) using second order generalised estimating equation. RESULTS: Of the 3851 eligible individuals, 3314 subjects participated in the study. After applying the exclusion criteria, data from 2667 subjects was used in the analysis. The prevalence of keratoconus in the present population was 4% (95% CI: 3-4). The odds of keratoconus were significantly higher in males (OR = 2.30, p = 0.032). To investigate the familial aggregation of keratoconus, we only evaluated families from which at least two members participated in the study. So, 403 families (1452 participants) were evaluated. Our results showed a higher odds ratio for the sibling pairs compare to parent-offspring pairs and as reported, the odds ratio of the spouses was less than 1.0. CONCLUSION: Our findings showed a relatively high prevalence and familial aggregation of keratoconus in rural areas of Iran, independent of age, sex, and place of residence. This aggregation may be due to heredity or the effect of undetermined shared environmental factors. PMID- 29572901 TI - Do hepatitis B virus surface antigens have any role in viral carcinogenesis? PMID- 29572902 TI - 2-fluoro-5-maleimidobenzoic acid-linked albumin drug (MAD) delivery for selective systemic targeting of metastatic prostate cancer. AB - BACKGROUND: The SH-group at Cys-34 of human serum albumin (HSA) is a unique and accessible functional group that can be exploited for efficient linkage of a maleimide containing cytotoxic drug derivative to albumin. The specific maleimide chemistry used for production of the maleimide-linked albumin drug (MAD) is critical, however, to minimize the plasma concentration of "free" cytotoxic drug spontaneously released from albumin carrier thus decreasing dose-limiting host toxicity while enhancing the plasma half-life from minutes to days (ie, pharmacokinetic effect) and tissue concentration of the MAD in the extracellular cellular fluid at sites of cancer (ie, EPR effect). METHODS: To accomplish this goal, a chemical synthesis was developed using 2-fluoro-5-maleimidobenzoic acid to stably link the potent cytotoxic chemically modified analogue of the naturally occurring sesquiterpene gamma-lactone, thapsigargin, 8-O-(12-aminododecanoyl)-8-O debutanoyl thapsigargin (12ADT), to Cys-34 of albumin to produce 12ADT-MAD. RESULTS: Using FITC-labeling, LC/MS analysis, and in vitro growth and clonogenic survival assays on a series of 6 human prostate cancer lines (LNCaP, LAPC-4, VCap, CWR22Rv 1, PC3, and Du145), we documented that 12ADT-MAD is endocytosed by prostate cancer cells where it is degraded into its amino acids liberating cysteinyl-maleimide-12ADT which is both chemically stable at the acidic pH of 5.5 present in the endosome while retaining its high killing ability (IC50 50 nM) via SERCA inhibition. CONCLUSIONS: Based upon these positive in vitro validation results, the in vivo efficacy versus host toxicity of this 12-ADT-MAD approach is presently being evaluated against a series of patient derived androgen responsive and castration resistant human xenografts in immune-deficient mice. PMID- 29572903 TI - Quantification of metronidazole in human plasma using a highly sensitive and rugged LC-MS/MS method for a bioequivalence study. AB - A highly sensitive, selective and rugged method has been described for the quantification of metronidazole (MTZ) in human plasma by liquid chromatography tandem mass spectrometry using metronidazole-d4 as the internal standard (IS). The analyte and the IS were extracted from 100 MUL plasma by liquid-liquid extraction. The clear samples obtained were chromatographed on an ACE C18 (100 * 4.6 mm, 5 MUm) column using acetonitrile and 10.0 mm ammonium formate in water, pH 4.00 (80:20, v/v) as the mobile phase. A triple quadrupole mass spectrometer system equipped with turbo ion spray source and operated in multiple reaction monitoring mode was used for the detection and quantification of MTZ. The calibration range was established from 0.01 to 10.0 MUg/mL. The results of validation testing for precision and accuracy, selectivity, matrix effects, recovery and stability complied with current bioanalytical guidelines. A run time of 3.0 min permitted analysis of more than 300 samples in a day. The method was applied to a bioequivalence study with 250 mg MTZ tablet formulation in 24 healthy Indian males.

PMID- 29572906 TI - Epigallocatechin-3-gallate partially restored redox homeostasis in arsenite stressed keratinocytes. AB - Arsenite (AsIII) is known for inducing severe oxidative stress and skin carcinogenesis. Contrastingly, phytochemical, epigallocatechin-3-gallate (EGCG) combats toxic insults. Our study focused on the effect of EGCG on redox status of AsIII-stressed normal human keratinocytes, HaCaT cells. EGCG (50 MUm) increased the cell viability by 29% in AsIII (50 MUm) insulted HaCaT cells but exhibited pro-oxidant activity by elevated expression of the oxidative stress markers. EGCG was effective not only in reducing AsIII-induced nuclear expression of Nrf2 and Nrf2Ser40 but also in increasing nuclear expression of Keap1 both at protein and mRNA level. EGCG did not have similar effects on all Nrf2 downstream targets. EGCG elevated expression of HO-1 and gamma-GCL,showed no change in MRP1 but decreased superoxide dismutase, NAD(P)H dehydrogenase quinone 1 and glutathione S transferase activity in AsIII-treated HaCaT cells. EGCG along with AsIII caused decreased phosphorylation of Nrf2 at ser40 residue, which might have facilitated Keap1-mediated nuclear export and degradation of Nrf2 and paved the pro-survival signal for AsIII-insulted HaCaT cells. In conclusion, it might be indicated that EGCG in spite of inducing the pro-oxidant effect was effective in increasing the viability of AsIII-treated HaCaT cells by partially restoring the Nrf2/Keap1 mediated signaling axis. PMID- 29572905 TI - Infection with a Brazilian isolate of Zika virus generates RIG-I stimulatory RNA and the viral NS5 protein blocks type I IFN induction and signaling. AB - Zika virus (ZIKV) is a major public health concern in the Americas. We report that ZIKV infection and RNA extracted from ZIKV infected cells potently activated the induction of type I interferons (IFNs). This effect was fully dependent on the mitochondrial antiviral signaling protein (MAVS), implicating RIG-I-like receptors (RLRs) as upstream sensors of viral RNA. Indeed, RIG-I and the related RNA sensor MDA5 contributed to type I IFN induction in response to RNA from infected cells. We found that ZIKV NS5 from a recent Brazilian isolate blocked type I IFN induction downstream of RLRs and also inhibited type I IFN receptor (IFNAR) signaling. We defined the ZIKV NS5 nuclear localization signal and report that NS5 nuclear localization was not required for inhibition of signaling downstream of IFNAR. Mechanistically, NS5 blocked IFNAR signaling by both leading to reduced levels of STAT2 and by blocking phosphorylation of STAT1, two transcription factors activated by type I IFNs. Taken together, our observations suggest that ZIKV infection induces a type I IFN response via RLRs and that ZIKV interferes with this response by blocking signaling downstream of RLRs and IFNAR.

Noble) juice pomace on Amberlite FPX66 resin in a fixed bed column. AB - BACKGROUND: Muscadine grape pomace, a by-product of juicing and wine-making, contains significant amounts of anthocyanin 3,5-diglucosides, known to be beneficial to human health. RESULTS: The objective of this research was to use mathematical modeling to investigate the adsorption/desorption characteristics of these anthocyanins from muscadine grape pomace on Amberlite FPX66 resin in a fixed bed column. Anthocyanins were extracted using hot water and ultrasound, and the extracts were loaded onto a resin column at five bed depths (5, 6, 8, 10 and 12 cm) using three flow rates (4, 6 and 8 mL min-1 ). It was found that adsorption on the column fitted the bed depth service time (BDST) model and the empty bed residence time (EBRT) model. Desorption was achieved by eluting the column using ethanol at four concentrations (25, 40, 55 and 70% v/v) and could be described with an empirical sigmoid model. The breakthrough curves of anthocyanins fitted the BDST model for all three flow rates with R2 values of 0.983, 0.992 and 0.984 respectively. The EBRT model was successfully employed to find the operating lines, which allow for column scale-up while still achieving similar results to those found in a laboratory operation. Desorption with 40% (v/v) ethanol achieved the highest recovery rate of anthocyanins at 79.6%. CONCLUSION: The mathematical models established in this study can be used in designing a pilot/industrial- scale column for the separation and concentration of anthocyanins from muscadine juice pomace.

AB - Expectations of an event can facilitate its neural processing. One of the ways we build expectations is through associative learning. Interestingly, the learning of contingencies between events can also occur without intention. Here, we study feature-based attention during associative learning, by asking how a learned association between a cue and a target outcome impacts the attention allocated to this outcome. Moreover, we investigate attention in learning depending on the intention to learn the association. We used an associative learning paradigm where we manipulated outcome predictability and intention to learn an association within streams of cue-target outcome visual stimuli, while stimulus characteristics and probability were held constant. In order to measure the event related component N2pc, widely recognized to reflect allocation of spatial attention, every outcome was embedded among distractors. Importantly, the location of the target outcome could not be anticipated. We found that predictable target outcomes showed an increased spatial attention as indexed by a greater N2pc component. A later component, the P300, was sensitive to the intention to learn the association between the cue and the target outcome. The current study confirms the remarkable ability of the brain to extract and update predictive information, in accordance with a predictive-coding model of brain function. Associative learning can guide a visual search and shape covert attentional selection in our rich environments. PMID- 29572910 TI - Na+ -taurocholate cotransporting polypeptide inhibition has hepatoprotective effects in cholestasis in mice. AB - : Accumulation of bile salts (BSs) during cholestasis leads to hepatic and biliary injury, driving inflammatory and fibrotic processes. The Na+ Taurocholate Cotransporting Polypeptide (NTCP) is the major hepatic uptake transporter of BSs, and can be specifically inhibited by myrcludex B. We hypothesized that inhibition of NTCP dampens cholestatic liver injury. Acute cholestasis was induced in mice by a 3.5-diethoxycarbonyl-1.4-dihydrocollidine (DDC) diet or by bile duct ligation (BDL). Chronic cholestasis was investigated in Atp8b1-G308V and Abcb4/Mdr2 deficient mice. Mice were injected daily with myrcludex B or vehicle. Myrcludex B reduced plasma alkaline phosphatase (ALP) levels in DDC-fed, Atp8b1-G308V and BDL mice by 39%, 27% and 48% respectively. Expression of genes involved in fibrosis, proliferation and inflammation was reduced by myrcludex B treatment in DDC-fed and Atp8b1-G308V mice. NTCP inhibition increased plasma BS levels from 604+/-277 to 1746+/-719 MUm in DDC-fed mice, 432+/-280 to 762+/-288 MUm in Atp8b1-G308V mice and from 522+/-130 to 3625+/-378 MUm in BDL mice. NTCP-inhibition strongly aggravated weight loss in BDL mice, but not in other cholestatic models studied. NTCP-inhibition reduced biliary BS output in DDC-fed and Atp8b1-G308V mice by ~50% while phospholipid (PL) output was maintained, resulting in a higher PL/BS ratio. Conversely, liver injury in Abcb4 deficient mice, lacking biliary phospholipid output, was aggravated after myrcludex B treatment. CONCLUSION: NTCP-inhibition by myrcludex B has hepatoprotective effects, by reducing BS load in hepatocytes and increasing the biliary PL/BS ratio. High micromolar plasma BS levels after NTCP-inhibition were well tolerated. NTCP-inhibition may be beneficial in selected forms of cholestasis. (Hepatology 2018). PMID- 29572913 TI - Correlation between electromyography and perineometry in evaluating pelvic floor muscle function in nulligravidas: A cross-sectional study. AB - OBJECTIVE: To correlate the results of electromyography and perineometry in the assessment of PFM function in nulligravidas. METHODS: The cross-sectional observational study was approved by the internal review board of the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) and was conducted in the Instituto Paraibano de Pesquisa Professor Joaquim Amorim Neto (IPESQ). Thirty eight nulligravidas aged 18-39 years of age, who had already initiated their sexual life, participated in the study. Exclusion criteria consisted of the presence of genital prolapse, a history of pelvic or urogenital surgery and the presence of neurological disease producing muscle disorders. For the evaluation procedure, the women were submitted to a clinical evaluation of the pelvic floor muscles followed by electromyography. Perineometry was performed 72 h later. Prior to electromyography and perineometry, the women were given standardized training with electromyographic biofeedback to teach them to contract only their pelvic floor muscles. RESULTS: A highly positive, statistically significant correlation (r = 0.968; P < 0.001) was found between the electromyographic and perineometric findings. CONCLUSIONS: A strong correlation was found between perineometric and electromyographic findings of pelvic floor muscle function.

AB - OBJECTIVE: Impairment of speech repetition following injury to the dorsal language stream is a feature of conduction aphasia, a well-described "disconnection syndrome" in adults. The impact of similar lesions sustained in infancy has not been established. METHODS: We compared language outcomes in term born individuals with confirmed neonatal stroke (n = 30, age = 7-18 years, left sided lesions in 21 cases) to matched controls (n = 40). Injury to the dorsal and/or ventral language streams was assessed using T1 - and T2 -weighted magnetic resonance imaging (MRI) and diffusion tractography. Language lateralization was determined using functional MRI. RESULTS: At the group level, left dorsal language stream injury was associated with selective speech repetition impairment for nonwords (p = 0.021) and sentences (p < 0.0001). The majority of children with significant repetition impairment had retained left hemisphere language representation, but right hemisphere dominance was correlated with minimal or absent repetition deficits. Post hoc analysis of the repetition-impaired group revealed additional language-associated deficits, but these were more subtle and variable. INTERPRETATION: We conclude that (1) despite the considerable plasticity of the infant brain, early dorsal language stream injury can result in specific and long-lasting problems with speech repetition that are similar to the syndrome of conduction aphasia seen in adults; and (2) language reorganization to the contralateral hemisphere has a protective effect.

PMID- 29572919 TI - A novel, efficient, and ecologically relevant bioassay method using aquatic fungi and fungus-like organisms for fungicide ecological effect assessment. AB - Fungicides are used to control fungal plant pathogens, but they may also be highly toxic to aquatic fungi, which play an important role in natural aquatic ecosystems. However, a bioassay method using aquatic fungi has not been sufficiently developed. In the present study, a novel, efficient, and ecologically relevant bioassay method was developed for the ecological effect assessment of fungicides. Candidate test species were selected by considering the following 4 factors: 1) their ecological relevance (i.e., widely distributed and frequently observed) in freshwater habitats, 2) inclusion of a wide range of taxonomic groups, 3) availability from public culture collections, and 4) suitability for culture experiments using a microplate. The following 5 fungal species were selected: Rhizophydium brooksiaum (Chitridiomycota), Chytriomyces hyalinus (Chitridiomycota), Tetracladium setigerum (Ascomycota), Sporobolomyces roseus (Basidiomycota), and Aphanomyces stellatus (Oomycota, fungus-like organism). An efficient test method using the 5 species was developed based on a microplate assay using a 96-well white microplate and a test duration of 48 h. Fungal biomass was determined as adenosine 5'-triphosphate (ATP) luminescence, which is known to be proportional to live cell density and can be determined with a microplate reader. Test performance was evaluated by conducting bioassays of 3,5-dichlorophenol and malachite green as standard test substances. Fungal species were clearly more sensitive than other species to the fungicide malachite green. Environ Toxicol Chem 2018;37:1980-1989. (c) 2018 SETAC. PMID- 29572917 TI - The effects of galectin-3 depletion apheresis on induced skin inflammation in a porcine model. AB - Galectin-3 (Gal-3), a beta-galactoside-binding lectin that is expressed in mammalian cells, is known to modulate several biological functions such as cell cell adhesion, macrophage activation, angiogenesis, metastasis, and fibrosis. The goal of this study was to evaluate the ability of Gal-3 depletion apheresis using an adsorption column with immobilized anti-Gal-3-antibody to reduce inflammation induced by Complete Freund's Adjuvant injection in a skin inflammation porcine model. Here, we report that plasma perfusion by apheresis through a Gal-3 binding immuno-affinity column reduces plasma Gal-3 levels to below limits of quantitative detection, and results in significant decrease in skin inflammation, including degree and duration of inflammatory lesions. Human plasma was tested ex vivo and found to be efficiently depleted using the anti-Gal-3 affinity column. This study demonstrates the potential of Gal-3 depletion apheresis as a therapeutic method for inflammation-mediated disease, supporting continued research in this area for clinical application. PMID- 29572918 TI - Status epilepticus: Role for etiology in determining response to benzodiazepines. AB - OBJECTIVE: Clinical factors contributing to benzodiazepine failure in treating status epilepticus (SE) include suboptimal dosing and seizure duration. As many benzodiazepine-refractory episodes of SE arise from acute etiologies, we sought to determine whether etiology impacts SE treatment. METHODS: The potency of diazepam to terminate SE induced by lithium-pilocarpine (LiPilo-SE) or kainic acid (KA-SE) in 3-week-old rats was studied by video-electroencephalography. Synaptic gamma-aminobutyric acid type A receptor (GABAR)-mediated currents were recorded from dentate granule cells using voltage-clamp electrophysiology. Surface expression of gamma2 subunit-containing GABARs and Kv4.2 potassium channels in hippocampal slices was determined using a biotinylation assay. Expression of phosphorylated forms of beta2/3 and gamma2 subunits was determined using phosphospecific antibodies and Western blotting. RESULTS: Diazepam failed to terminate late SE in LiPilo-SE animals but was successful in terminating KA-SE of 1- and 3-hour duration. One hour after SE onset, GABAR-mediated synaptic inhibition and gamma2 subunit-containing GABAR surface expression were reduced in LiPilo-SE animals. These were unchanged in KA-SE animals at 1 and 3 hours. Phosphorylation of gamma2 subunit residue S327 was unchanged in both models, although GABAR beta3 subunit S408/409 residues were dephosphorylated in the LiPilo-SE animals. Kv4.2 potassium channel surface expression was increased in LiPilo-SE animals but reduced in KA-SE animals. INTERPRETATION: SE-model dependent differences support a novel hypothesis that the development of benzodiazepine pharmacoresistance may be etiologically predetermined. Further studies are required to investigate the mechanisms that underlie such etiological differences during SE and whether etiology-dependent protocols for the treatment of SE need to be developed.

AB - OBJECTIVES: Within programmatic assessment, the ambition is to simultaneously optimise the feedback and the decision-making function of assessment. In this approach, individual assessments are intended to be low stakes. In practice, however, learners often perceive assessments designed to be low stakes as high stakes. In this study, we explored how learners perceive assessment stakes within programmatic assessment and which factors influence these perceptions. METHODS: Twenty-six learners were interviewed from three different countries and five different programmes, ranging from undergraduate to postgraduate medical education. The interviews explored learners' experience with and perception of assessment stakes. An open and qualitative approach to data gathering and analyses inspired by the constructivist grounded theory approach was used to analyse the data and reveal underlying mechanisms influencing learners' perceptions. RESULTS: Learners' sense of control emerged from the analysis as key for understanding learners' perception of assessment stakes. Several design factors of the assessment programme provided or hindered learners' opportunities to exercise control over the assessment experience, mainly the opportunities to influence assessment outcomes, to collect evidence and to improve. Teacher learner relationships that were characterised by learners' autonomy and in which learners feel safe were important for learners' believed ability to exercise control and to use assessment to support their learning. CONCLUSIONS: Knowledge of the factors that influence the perception of assessment stakes can help design effective assessment programmes in which assessment supports learning. Learners' opportunities for agency, a supportive programme structure and the role of the teacher are particularly powerful mechanisms to stimulate the learning value of programmatic assessment. PMID- 29572921 TI - Postoperative urinary retention after pelvic organ prolapse repair: Vaginal versus robotic transabdominal approach. AB - AIMS: Postoperative urinary retention has been reported in 13-32% of patients that undergo pelvic organ prolapse (POP) repair. The purpose of our study was to compare rates of urinary retention between transvaginal and robotic transabdominal approaches and identify risk factors for postoperative urinary retention following POP repair. METHODS: Medical records of patients that underwent POP repair were reviewed. Surgeries included transvaginal high uterosacral ligament suspension (HUSLS) and robotic-assisted sacral colpopexy (RASCP). All patients underwent a retrograde fill voiding trial (RGVT) postoperatively. Demographics, comorbidities, preoperative urodynamic findings, and surgical procedures were compared between women that passed their RGVT and those that did not. RESULTS: Out of 484 patients reviewed, 333 underwent POP repair with a transvaginal HUSLS and 151 underwent RASCP. Postoperative urinary retention was identified in 128 (26.4%) patients where 113 underwent transvaginal HUSLS and 15 underwent RASCP. The odds ratio (OR) of postoperative urinary retention following transvaginal HUSLS was 3.26 (CI 1.72-6.18; P < 0.001) compared to RASCP. Older age was also a risk factor for postoperative urinary retention (OR 1.03, CI 1.01-1.05; P = 0.012). While parity, preoperative post void residual (PVR), and rates of concomitant transvaginal anterior/posterior repair were significantly higher in patients that developed postoperative urinary retention on univariate analysis, these factors did not demonstrate significance on multivariate analysis. CONCLUSIONS: Transvaginal HUSLS demonstrates a 3.26 OR for postoperative urinary retention compared to the robotic transabdominal approach. Older age is also a significant risk factor whereas parity, preoperative PVR, and rates of concomitant transvaginal anterior/posterior repair were not significant risk factors on multivariate analysis.

AB - Tylvalosin (TVN) is a water soluble macrolide used in swine production to treat enteric, respiratory, and arthritic pathogens. There is limited data on its distribution to synovial fluid beyond gavage studies, which do not represent field conditions. This study measured water disappearance, TVN concentration in the medicated water, daily dose, and concentrations of TVN and 3-O-acetyltylosin (3AT) in the synovial fluid and plasma of treated pigs over the administration period. The study emphasized understanding variation in tissue TVN concentrations within the context of a field setting. Sixty finisher pigs were housed individually with individual waterers. Six pigs were randomly allocated to the following time points for sample collection: 0, 48, 60, 72, 84, 96, 102, 108, 114, and 120 hr on medication. TVN was administered daily in the water for 5 days. Water disappearance and medicated water concentration were measured daily. At each time point, six pigs were euthanized and plasma and synovial fluid were collected for analysis. Median TVN synovial fluid concentrations ranged between <1 ng/ml (hour 0) to 3.6 ng/ml (hour 84). There was substantial variation between individual pigs for water disappearance (mean 4.36L and range 0-7.84). Median TVN water concentration was 59 ppm (range 38-75 ppm). PMID- 29572925 TI - Correlating S100B with disease course in a case of new onset, acquired thrombotic thrombocytopenic purpura (TTP): Could this be a new predictive biomarker in TTP? AB - Acute thrombotic thrombocytopenic purpura (TTP) is an aggressive thrombotic microangiopathy that if not treated, can have a 90% mortality rate. Clinical manifestations of this disease include profound thrombocytopenia, hemolytic anemia, and end-organ dysfunction. Neurologic symptoms can occur in 80% of patients and range from mild confusion to coma (Scully et al., Br J Haematol 142:819-826). Here, we present the clinical course of a patient diagnosed with new onset acquired TTP who presented with neurologic changes that waxed and waned during her disease course. In addition to usual clinical and laboratory markers for TTP severity and activity, we also collected and analyzed the protein S100B, an astroglial protein studied as a marker for central nervous system injury and impairment of the blood-brain barrier. Our hypothesis here is that because TTP involves endovascular damage, S100B could function as a biomarker for neurologic dysfunction and ultimately, predict disease activity. As illustrated in this case, our patient's S100B levels did appear to correlate with TTP disease activity and the trajectory of this protein seemed a better predictor of cognitive function. Furthermore, increased S100B velocity seemed to be the earliest indicator of a refractory TTP disease process requiring more intensive plasma exchange (TPE) therapy regimen. Therefore, we would suggest that S100B is a promising predictive biomarker of disease activity in guiding the intensity of TPE therapy for TTP as well as cognitive function. PMID- 29572926 TI - Regional brain volumetry and brain function in severely brain-injured patients. AB - OBJECTIVE: The relationship between residual brain tissue in patients with disorders of consciousness (DOC) and the clinical condition is unclear. This observational study aimed to quantify gray (GM) and white matter (WM) atrophy in states of (altered) consciousness. METHODS: Structural T1-weighted magnetic resonance images were processed for 102 severely brain-injured and 52 healthy subjects. Regional brain volume was quantified for 158 (sub)cortical regions using Freesurfer. The relationship between regional brain volume and clinical characteristics of patients with DOC and conscious brain-injured patients was assessed using a linear mixed-effects model. Classification of patients with unresponsive wakefulness syndrome (UWS) and minimally conscious state (MCS) using regional volumetric information was performed and compared to classification using cerebral glucose uptake from fluorodeoxyglucose positron emission tomography. For validation, the T1-based classifier was tested on independent datasets. RESULTS: Patients were characterized by smaller regional brain volumes than healthy subjects. Atrophy occurred faster in UWS compared to MCS (GM) and conscious (GM and WM) patients. Classification was successful (misclassification with leave-one-out cross-validation between 2% and 13%) and generalized to the independent data set with an area under the receiver operator curve of 79% (95% confidence interval [CI; 67-91.5]) for GM and 70% (95% CI [55.6-85.4]) for WM. INTERPRETATION: Brain volumetry at the single-subject level reveals that regions in the default mode network and subcortical gray matter regions, as well as white matter regions involved in long range connectivity, are most important to distinguish levels of consciousness. Our findings suggest that changes of brain structure provide information in addition to the assessment of functional neuroimaging and thus should be evaluated as well. Ann Neurol 2018;83:842-853. PMID- 29572927 TI - Factors affecting use of word-of-mouth by dental patients. AB - OBJECTIVES: Word-of-mouth (WOM) refers to communication among consumers, which greatly influences the marketing strategies of dental clinics. This study aimed to explore factors that affect use of WOM by dental patients and to analyse their pathways. METHODS: The participants were 520 outpatients from four private dental clinics. Data were obtained from a survey using self-reported questionnaires, which included questions regarding seven latent variables: five exogenous variables, including medical service quality (physical environment, customer service, patient relationship quality) and individual characteristic variables (opinion leader tendency, social hub tendency); and two endogenous variables (intention to recommend, WOM experience). Statistical analysis was performed using structural equation modelling. RESULTS: Significant associations were found in the pathways between relationship quality and intention to recommend, intention to recommend and WOM, and opinion leader tendency and WOM (P < 0.001). Higher patient relationship quality and higher intention to recommend were related to positive WOM, as was higher opinion leader tendency. CONCLUSIONS: Improving patient relationship quality can promote positive WOM for dental clinics. Strategies are needed to promote a positive perception of dental clinics by effectively responding to the views of patients with strong opinion leader tendencies.

AB - BACKGROUND: Dysfunction of NaV 1.5 encoded by SCN5A accounts for approximately half of the channelopathic SIDS cases. We investigated the functional effect of two gene variants identified in the same patient, one in SCN5A and one in SCN1Bb. The aim of the study was to risk stratify the proband's family. METHODS: The family was referred for cardiovascular genetic evaluation to assess familial risk of cardiac disease. Functional analysis of the identified variants was performed with patch-clamp electrophysiology in HEK293 cells. RESULTS: A 16-month-old healthy boy died suddenly in the context of nonspecific illness and possible fever. Postmortem genetic testing revealed variants in the SCN5A and SCN1Bb genes. The proband's father carries the same variants but is asymptomatic. Electrophysiological analysis of the NaV 1.5_1281X truncation revealed complete loss-of-function of the channel. Coexpression of NaV 1.5 with NaV beta1b significantly increased INa density when compared to NaV 1.5 alone. The NaV beta1b _V268I variant abolished this INa density increase. Moreover, it shifted the activation curve toward more depolarized potentials. CONCLUSIONS: Genetic variation of both sodium channel and its modifiers may contribute to sudden unexplained death in childhood. However, the asymptomatic father suggests that genetic variation of these genes is not sufficient to cause sudden death or clinically detectable SCN5A phenotypes.

PMID- 29572931 TI - Genetic predisposition in anti-LGI1 and anti-NMDA receptor encephalitis. AB - We performed a genome-wide association study in 1,194 controls and 150 patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR, n = 96) or anti-leucine-rich glioma-inactivated1 (anti-LGI1, n = 54) autoimmune encephalitis. Anti-LGI1 encephalitis was highly associated with 27 single-nucleotide polymorphisms (SNPs) in the HLA-II region (leading SNP rs2858870 p = 1.22 * 10-17 , OR = 13.66 [7.50 24.87]). Potential associations, below genome-wide significance, were found with rs72961463 close to the doublecortin-like kinase 2 gene (DCLK2) and rs62110161 in a cluster of zinc-finger genes. HLA allele imputation identified association of anti-LGI1 encephalitis with HLA-II haplotypes encompassing DRB1*07:01, DQA1*02:01 and DQB1*02:02 (p < 2.2 * 10-16 ) and anti-NMDAR encephalitis with HLA-I allele B*07:02 (p = 0.039). No shared genetic risk factors between encephalitides were identified. Ann Neurol 2018;83:863-869. PMID- 29572932 TI - Development of an institutional assessment framework.

PMID- 29572934 TI - Feedforward neural control of toe walking in humans. AB - KEY POINTS: Activation of ankle muscles at ground contact during toe walking is unaltered when sensory feedback is blocked or the ground is suddenly dropped. Responses in the soleus muscle to transcranial magnetic stimulation, but not peripheral nerve stimulation, are facilitated at ground contact during toe walking. We argue that toe walking is supported by feedforward control at ground contact. ABSTRACT: Toe walking requires careful control of the ankle muscles in order to absorb the impact of ground contact and maintain a stable position of the joint. The present study aimed to clarify the peripheral and central neural mechanisms involved. Fifteen healthy adults walked on a treadmill (3.0 km h-1 ). Tibialis anterior (TA) and soleus (Sol) EMG, knee and ankle joint angles, and gastrocnemius-soleus muscle fascicle lengths were recorded. Peripheral and central contributions to the EMG activity were assessed by afferent blockade, H reflex testing, transcranial magnetic brain stimulation (TMS) and sudden unloading of the planter flexor muscle-tendon complex. Sol EMG activity started prior to ground contact and remained high throughout stance. TA EMG activity, which is normally seen around ground contact during heel strike walking, was absent. Although stretch of the Achilles tendon-muscle complex was observed after ground contact, this was not associated with lengthening of the ankle plantar flexor muscle fascicles. Sol EMG around ground contact was not affected by ischaemic blockade of large-diameter sensory afferents, or the sudden removal of ground support shortly after toe contact. Soleus motor-evoked potentials elicited by TMS were facilitated immediately after ground contact, whereas Sol H-reflexes were not. These findings indicate that at the crucial time of ankle stabilization following ground contact, toe walking is governed by centrally mediated motor drive rather than sensory driven reflex mechanisms. These findings have implications for our understanding of the control of human gait during voluntary toe walking. PMID- 29572936 TI - Long-term outcomes of posterior chamber phakic intraocular lens implantation in keratoconus. AB - BACKGROUND: In this retrospective observational case series study, the aim was to evaluate the long-term safety, efficacy, stability and predictability of posterior chamber phakic intraocular lens (pIOL) implantation to correct myopia and myopic astigmatism associated with keratoconus. METHODS: Uncorrected distance visual acuity (UDVA), best spectacle-corrected distance visual acuity (BSCDVA), refraction and adverse effects were evaluated in 23 keratoconic eyes of 13 patients after five years with Visian ICMV4 pIOL (STAAR Surgical). RESULTS: The mean pre-operative spherical equivalent and cylinder changed from -5.35 +/- 2.82 D and -3.14 +/- 1.58 D to -0.78 +/- 1.31 D and -1.56 +/- 1.53 D, respectively, five years post-operatively. Before the surgery the mean Snellen decimal BSCDVA was 0.60 +/- 0.20. The mean UDVA and BSCDVA changed to 0.74 +/- 0.22 and 0.88 +/- 0.16, respectively. A total of 82.5 per cent of eyes achieved 6/12 or better UDVA post-operatively. The mean safety and efficacy indices were respectively, 1.47 +/ 0.32 and 1.24 +/- 0.34. No eye lost a line of visual acuity and 19 eyes gained one or more lines. An endothelial cell loss of 7.88 per cent occurred. No significant changes were seen in intraocular pressure, steep, flat and mean keratometry. The crystalline lens was clear. CONCLUSION: The clinical outcomes of the current study demonstrate the safety, efficacy and predictability of the implantable collamer lens (toric and non-toric) in the correction of myopia and myopic astigmatism associated with keratoconus. The patients' refractions achieved early stability and remained stable during the course of the study. PMID- 29572935 TI - Effect of interleukin-1beta on occludin mRNA expression in the duodenal and colonic mucosa of dogs with inflammatory bowel disease. AB - BACKGROUND: Mucosal imbalance of interleukin (IL)-1beta and IL-1 receptor antagonist (Ra) has been reported in the duodenal mucosa of dogs with inflammatory bowel disease (IBD). However, the imbalance in the colonic mucosa and its role in duodenitis and colitis in IBD of dogs remain unclear. OBJECTIVES: To measure the expression of IL-1beta and IL-1Ra proteins in the colonic mucosa of dogs with IBD, and to determine the effect of IL-1beta on expression of occludin (ocln) mRNA, a tight junction component, in the duodenal and colonic mucosa of dogs with IBD. ANIMALS: Twelve dogs with IBD and 6 healthy dogs. METHODS: IL-1beta and IL-1 Ra proteins in the colonic mucosa were quantified by ELISA in 7 of the 12 dogs with IBD. Expression of ocln mRNA in the duodenal and colonic mucosa was examined in the 12 dogs by real-time PCR. RESULTS: The ratio of IL-1beta to IL-1Ra in the colonic mucosa was significantly higher in dogs with IBD than in healthy dogs. The ex vivo experiment determined that IL-1beta suppressed expression of ocln mRNA in the colonic mucosa, but not in the duodenal mucosa, of healthy dogs. Expression of ocln mRNA in the colonic mucosa, but not in the duodenal mucosa, was significantly lower in dogs with IBD than in healthy dogs. CONCLUSIONS AND CLINICAL IMPORTANCE: A relative increase in IL-1beta may attenuate ocln expression, leading to intestinal barrier dysfunction and promotion of intestinal inflammation in the colonic mucosa, but not in the duodenal mucosa, of dogs with IBD. PMID- 29572937 TI - Suitability of oral administration of monosodium phosphate, disodium phosphate, and magnesium phosphate for the rapid correction of hypophosphatemia in cattle. AB - BACKGROUND: Hypophosphatemia is commonly associated with disease and decreased productivity in dairy cows particularly in early lactation. Oral supplementation with phosphate salts is recognized as suitable for the rapid correction of hypophosphatemia. Little information is available about the differences in efficacy between salts used for oral phosphorus supplementation. OBJECTIVES: Comparison of efficacy of oral administration of NaH2 PO4 , Na2 HPO4 , and MgHPO4 in treating hypophosphatemia in cattle. ANIMALS: 12 healthy dairy cows in the fourth week of lactation in their second to fifth lactation. METHODS: Randomized clinical study. Phosphorus deficient, hypophosphatemic cows underwent a sham treatment and were afterwards assigned to 1 of 3 treatments-NaH2 PO4 , Na2 HPO4 , or MgHPO4 (each provided the equivalent of 60 g of phosphorus). Blood samples were obtained immediately before and repeatedly after treatment. RESULTS: Treatment with NaH2 PO4 and Na2 HPO4 resulted in rapid and sustained increases of plasma phosphate concentrations ([Pi]). Significant effects were apparent within 1 hour (NaH2 PO4 : P = .0044; Na2 HPO4 : P = .0077). Peak increments of plasma [Pi] of 5.33 mg/dL [5.26-5.36] and 4.30 mg/dL [3.59-4.68] (median and interquartile range) were reached after 7 and 6 hours in animals treated with NaPH2 PO4 and Na2 HPO4 , respectively, whereas treatment with MgHPO4 led to peak increments 14 hours after treatment (3.19 mg/dL [2.11-4.04]). CONCLUSIONS AND CLINICAL IMPORTANCE: NaH2 PO4 and Na2 HPO4 are suitable to rapidly correct hypophosphatemia in cattle. Because of the protracted and weaker effect, MgHPO4 cannot be recommended for this purpose. Despite important differences in solubility of NaH2 PO4 and Na2 HPO4 only small plasma [Pi] differences were observed after treatment. PMID- 29572938 TI - Prognostic value of echocardiographic indices of left atrial morphology and function in dogs with myxomatous mitral valve disease. AB - BACKGROUND: The prognostic relevance of left atrial (LA) morphological and functional variables, including those derived from speckle tracking echocardiography (STE), has been little investigated in veterinary medicine. OBJECTIVES: To assess the prognostic value of several echocardiographic variables, with a focus on LA morphological and functional variables in dogs with myxomatous mitral valve disease (MMVD). ANIMALS: One-hundred and fifteen dogs of different breeds with MMVD. METHODS: Prospective cohort study. Conventional morphologic and echo-Doppler variables, LA areas and volumes, and STE-based LA strain analysis were performed in all dogs. A survival analysis was performed to test for the best echocardiographic predictors of cardiac-related death. RESULTS: Most of the tested variables, including all LA STE-derived variables were univariate predictors of cardiac death in Cox proportional hazard analysis. Because of strong correlation between many variables, only left atrium to aorta ratio (LA/Ao > 1.7), mitral valve E wave velocity (MV E vel > 1.3 m/s), LA maximal volume (LAVmax > 3.53 mL/kg), peak atrial longitudinal strain (PALS < 30%), and contraction strain index (CSI per 1% increase) were entered in the univariate analysis, and all were predictors of cardiac death. However, only the MV E vel (hazard ratio [HR], 4.45; confidence interval [CI], 1.76-11.24; P < .001) and LAVmax (HR, 2.32; CI, 1.10-4.89; P = .024) remained statistically significant in the multivariable analysis. CONCLUSIONS AND CLINICAL IMPORTANCE: The assessment of LA dimension and function provides useful prognostic information in dogs with MMVD. Considering all the LA variables, LAVmax appears the strongest predictor of cardiac death, being superior to LA/Ao and STE-derived variables. PMID- 29572939 TI - Computed tomographic appearance of abdominal lymph nodes in healthy cats. AB - BACKGROUND: Computed tomography (CT) is commonly used in veterinary medicine and plays an important role in disease identification and cancer staging. Identification of abnormal abdominal lymph nodes is important for clinical, therapeutic, and prognostic decision making. No published study describes the CT appearance of abdominal lymph nodes in healthy cats. HYPOTHESIS/OBJECTIVES: All abdominal lymph centers will be identified on CT with the majority of lymph nodes being elongated and homogenously contrast enhancing. ANIMALS: Sixteen healthy cats without clinical or biochemical evidence of disease. METHODS: Precontrast and postcontrast CT images of sedated healthy cats were used to identify the presence and descriptive characteristics of intra-abdominal lymph nodes. These assessments then were compared with patient characteristics to identify possible correlations. RESULTS: Abdominal lymph nodes were readily identified on CT with caudal mesenteric, colic, hepatic, inguinal, and pancreaticoduodenal lymph nodes identified in 16/16 cats. Lymph node size and shape varied among lymph centers with nearly all lymph nodes homogeneously contrast enhancing in 515/525. Significant negative correlations were identified between age and length (P = .0166) and width (P = .0387) of abdominal lymph nodes as well as age and number of sacral lymph nodes (P = .0493). Intranodal fat was present in 18/525 lymph nodes. CONCLUSIONS AND CLINICAL IMPORTANCE: CT readily permitted identification and characterization of feline abdominal lymph nodes. This study provides subjective and objective data on the CT characteristics of abdominal lymph nodes in 16 healthy cats, with younger cats having larger abdominal lymph nodes and a higher number of sacral lymph nodes.

PMID- 29572941 TI - Detection and characterization of a rhabdovirus causing mortality in black bullhead catfish, Ameiurus melas. AB - This study fully describes a severe disease outbreak occurred in 2016 in black bullhead catfish farmed in Italy. Affected fish showed nervous clinical signs as well as emaciations and haemorrhagic petechiae on the skin at the fin bases, abdomen and gills. Viral isolation in cell culture allowed the subsequent identification of a rhabdovirus, tentatively named ictalurid rhabdovirus (IcRV), through electron microscopy, immunofluorescence and whole genome sequencing (WGS). The newly isolated virus, together with 14 additional viral strains stored in our repository and detected during similar mortality episodes in the period 1993-2016, was phylogenetically analysed on the basis of the nucleoprotein and the glycoprotein nucleotide and amino acid sequences. The genetic distances among Italian IcRV strains were also estimated. Our results show that all the IcRV strains belong to the genus Sprivivirus and are closely related to the tench rhabdovirus (TenRV). Italian catfish production is constantly decreasing, mainly due to viral infections, which include the newly characterized IcRV. Data presented in this work will assist to investigate the molecular epidemiology and the diffusive dynamics of this virus and to develop adequate surveillance activities. PMID- 29572942 TI - Sonographic features of peritoneal lymphomatosis in 4 cats. AB - BACKGROUND: The metastatic spread of feline lymphoma to the peritoneum ("lymphomatosis") has been rarely reported in the literature. The sonographic features specific to this rare disease manifestation have not been described and have important treatment and prognostic considerations prompting definitive diagnosis. OBJECTIVES: To describe the ultrasonic features of feline peritoneal lymphomatosis. ANIMALS: Four cats with alimentary lymphoma and peritoneal metastasis confirmed using cytology, histology, or both. RESULTS: The sonographic features described include either a nonobstructive, focally diffuse, and circumferential intestinal mass, or an eccentric, focally diffuse, gastric mass. The intestinal and gastric lesions exhibited hypo-to-anechoic transmural wall thickening with loss of wall layering in association with discrete-to-coalescing plaques or sheets of thickened, hypoechoic tissue throughout the mesentery or omenta. All cases exhibited only small volumes of anechoic free peritoneal fluid. Three of the 4 cats also had multiple small hypoechoic nodular foci on the parietal and/or visceral peritoneal surfaces. Two cats had bilateral renomegaly because of lymphoma invasion (2/4) and 1 cat had local lymphadenopathy secondary to lymphoma invasion (1/4). CONCLUSIONS AND CLINICAL IMPORTANCE: Peritoneal lymphomatosis is a rare manifestation of lymphoma metastasis and to date appears to be associated specifically with B-cell alimentary lymphoma. PMID- 29572943 TI - Urogenital anomalies and urinary incontinence in an English Cocker Spaniel dog with XX sex reversal. AB - A 3-year-old dog weighing 8 kg was referred with a disorder of sexual development and persistent urinary incontinence before and after gonadohysterectomy performed at a local animal hospital. Histopathological examination disclosed hypoplasia of the testes, epididymis, pampiniform plexus, and uterus. On ultrasonography, an anomalous structure containing anechoic fluid was identified in the region dorsal to the urinary bladder. An anomalous communication between the proximal urethra and the remnant uterus and vagina was found on retrograde urethrography under fluoroscopy. Reflux of contrast medium into the anomalous structure, suspected to be the uterus and cranial vagina, from the urethra was detected. Computed tomography identified the anomalous structure between the rectum and urethra. The anomalous structure was removed via laparotomy and the urinary incontinence resolved. The diagnosis of XX sex reversal with a developmental anomaly of the genitourinary tract was made on the basis of laparotomy findings and cytogenetic and SRY gene analyses. PMID- 29572944 TI - Kinetic and kinematic follow-up gait analysis in Doberman Pinschers with cervical spondylomyelopathy treated medically and surgically. AB - BACKGROUND: The efficacy of treatment of dogs with cervical spondylomyelopathy (CSM) is commonly based on the owner's and clinician's perception of the gait, which is highly subjective and suffers from observer bias. HYPOTHESIS/OBJECTIVES: To compare selected kinetic and kinematic parameters before and after treatments and to correlate the findings of gait analysis to clinical outcome. ANIMALS: Eight Doberman Pinschers with CSM confirmed by magnetic resonsance imaging. METHODS: Patients were prospectively studied and treated with either medical management (n = 5) or surgery (n = 3). Force plate analysis and 3-D kinematic motion capture were performed at initial presentation and approximately 8 weeks later. Force plate parameters evaluated included peak vertical force (PVF). Kinematic parameters measured included number of pelvic limb strides, stifle flexion and extension, maximum and minimum thoracic limb distance, truncal sway, and thoracic limb stride duration. RESULTS: Kinematic analysis showed that deviation of the spine to the right (truncal sway) was significantly smaller (P < .001) and the degree of right stifle flexion was significantly larger (P = .029) after treatment. Force plate analysis indicated that PVF was significantly different after treatment (P = .049) and the difference of the PVF also was significantly larger (P = .027). However, no correlation was found with either method of gait analysis and clinical recovery. CONCLUSIONS AND CLINICAL IMPORTANCE: Kinetic and kinematic gait analysis were able to detect differences in dogs with CSM before and after treatment. A correlation of gait analysis to clinical improvement could not be determined.

AB - Lectins known to possess an additional enzymatic function are called leczymes. Previous studies reported a unique polyphenol oxidase (PPO) activity in DLL-II-a leczyme from Dolichos lablab. DLL-II shares a high sequence and structural homology with DBL-another leczyme from Dolichos biflorus. Incidentally, DBL possesses lipoxygenase activity, but not the PPO activity. Legume lectins usually possess two metal-binding sites A and B. Although these sites are conserved in both DBL and DLL-II, site A in DLL-II is occupied by Mn2+ and site B by Ca2+ . In contrast, DLL-II binds Cu2+ and Ca2+ at sites A and B, respectively. Here, investigating the structural basis of PPO activity in DLL-II, we find that the PPO activity is only dependent on Cu2+ , but not Ca2+ ; and the lectin activity requires only Ca2+ . Further, our analysis suggests that an alternative mechanism of PPO reaction may be operative in DLL-II, which involves a mononuclear Cu2+ metal center; this is in contrast to the bi-nuclear Cu2+ metal center commonly observed in all PPOs. Importantly, structural and computational approaches employed here, we hypothesize possible PPO binding sites and the corresponding migration channels for accessing the active site.

AB - BACKGROUND: Prospective studies on maintenance treatment for Beagles with hereditary selective cobalamin (Cbl) malabsorption (Imerslund-Grasbeck syndrome, IGS) are lacking. In our experience, measurement of methylmalonic acid (MMA), a Cbl-dependent metabolite, seems more helpful to monitor Cbl status as compared with serum Cbl concentrations. OBJECTIVES: To evaluate a standardized Cbl supplementation scheme in Beagles with IGS. We hypothesized that a single parenteral dose of 1 mg hydroxocobalamin (OH-Cbl) would maintain clinical and metabolic remission for up to 2 months. ANIMALS: Six client-owned juvenile Beagles with genetically confirmed IGS and 28 healthy control dogs. METHODS: Prospective study. Monthly IM OH-Cbl (1 mg) supplementation was done over a median of 9 months (range, 6-13) in 6 dogs, followed by bimonthly (every 2 months) injections in 5 dogs over a median of 6 months (range, 3-10). Health status was assessed by routine clinical examinations at injection time points and owner observations. Voided urine samples were collected immediately before OH-Cbl injections for measurement of MMA-to-creatinine concentrations using a gas-liquid chromatography-tandem mass spectrometry (GC-MS) method. RESULTS: All dogs were clinically healthy while receiving monthly and bimonthly OH-Cbl supplementation. Urinary MMA results in healthy dogs ranged from 1.3 to 76.5 mmol/mol creatinine (median, 2.9). Median urinary MMA concentrations did not differ between dogs with IGS receiving monthly (n = 49; 5.3 mmol/mol creatinine; range, 2.3-50.4) and bimonthly (n = 31; 5.3 mmol/mol creatinine; range, 1.6-50) injections. CONCLUSIONS AND CLINICAL IMPORTANCE: A maintenance parenteral dose of 1 mg OH-Cbl monthly or bimonthly appears adequate in Beagles with IGS monitored by metabolic testing. PMID- 29572947 TI - Metabolic perturbations in Welsh Ponies with insulin dysregulation, obesity, and laminitis. AB - BACKGROUND: Metabolomics, the study of small-molecule metabolites, has increased understanding of human metabolic diseases, but has not been used to study equine metabolic syndrome (EMS). OBJECTIVES: (1) To examine the serum metabolome of Welsh Ponies with and without insulin dysregulation before and during an oral sugar test (OST). (2) To identify differences in metabolites in ponies with insulin dysregulation, obesity, or history of laminitis. ANIMALS: Twenty Welsh Ponies (mean +/- SD; 13.8 +/- 9.0 years) classified as non-insulin dysregulated [CON] (n = 10, insulin < 30 mU/L) or insulin dysregulated [ID] (n = 10, insulin > 60 mU/L) at 75 minutes after administration of Karo syrup, obese (n = 6) or nonobese (n = 14), and history of laminitis (n = 9) or no history of laminitis (n = 11). METHODS: Case-control study. Metabolomic analysis was performed on serum obtained at 0 minutes (baseline) and 75 minutes during the OST. Data were analyzed with multivariable mixed linear models with significance set at P <= .05. RESULTS: Metabolomic analysis of 646 metabolites (506 known) detected significant metabolite differences. At baseline, 55 metabolites (insulin response), 91 metabolites (obesity status), and 136 metabolites (laminitis history) were different. At 75 minutes, 51 metabolites (insulin response), 102 metabolites (obesity status), and 124 metabolites (laminitis history) were different. CONCLUSIONS AND CLINICAL IMPORTANCE: Use of metabolomics could have diagnostic utility for early detection of EMS and provide new knowledge regarding the pathophysiology of metabolic perturbations associated with this condition that might lead to improved clinical management. PMID- 29572948 TI - Longitudinal Change of Clinical and Biological Measures in Early Parkinson's Disease: Parkinson's Progression Markers Initiative Cohort. AB - OBJECTIVE: The objective of this study was to assess longitudinal change in clinical and dopamine transporter imaging outcomes in early, untreated PD. METHODS: We describe 5-year longitudinal change of the MDS-UPDRS and other clinical measures using results from the Parkinson's Progression Markers Initiative, a longitudinal cohort study of early Parkinson's disease (PD) participants untreated at baseline. We also provide data on the longitudinal change in dopamine transporter 123-I Ioflupane striatal binding and correlation between the 2 measures. RESULTS: A total of 423 PD participants were recruited, and 358 remain in the study at year 5. Baseline MDS-UPDRS total score was 32.4 (standard deviation 13.1), and the average annual change (assessed medications OFF for the treated participants) was 7.45 (11.6), 3.11 (11.7), 4(11.9), 4.7 (11.1), and 1.74(11.9) for years 1, 2, 3, 4, and 5, respectively (P < .0001 for the change over time), with a steeper change in year 1. Dopaminergic therapy had a significant effect on the change of MDS-UPDRS. There was a significant longitudinal change in dopamine transporter binding in all striatal regions (P < .001). There was a significant but weak correlation between MDS-UPDRS and dopamine transporter binding at baseline and years 1, 2, and 4, but no correlation between the rate of change of the 2 variables. CONCLUSIONS: We present 5-year longitudinal data on the change of the MDS-UPDRS and other clinical and dopamine transporter imaging outcome measures in early PD. These data can be used for sample size estimates for interventional studies in the de novo PD population. (c) 2018 The Authors.

PMID- 29572949 TI - Detection and seroprevalence of morbillivirus and other paramyxoviruses in geriatric cats with and without evidence of azotemic chronic kidney disease. AB - BACKGROUND: Feline morbillivirus (FeMV) is associated with the presence of tubulo interstitial nephritis (TIN) in cats, however the seroprevalence of FeMV in the UK and the association between the presence of FeMV and renal azotemia is unknown HYPOTHESIS/OBJECTIVES: To identify whether paramyxoviruses are present in urine samples of geriatric cats and to develop an assay to assess FeMV seroprevalence. To investigate the relationship between both urinary paramyxovirus (including FeMV) excretion and FeMV seroprevalence and azotemic chronic kidney disease (CKD). ANIMALS: Seventy-nine cats (40 for FeMV detection; 72 for seroprevalence). METHODS: Retrospective cross-sectional, case control study. Viral RNA was extracted from urine for RT-PCR. PCR products were sequenced for virus identification and comparison. The FeMV N protein gene was cloned and partially purified for use as an antigen to screen cat sera for anti-FeMV antibodies by Western Blot. RESULTS: Feline morbillivirus RNA from five distinct morbilliviruses were identified. Detection was not significantly different between azotemic CKD (1/16) and nonazotemic groups (4/24; P = .36). Three distinct, non-FeMV paramyxoviruses were present in the nonazotemic group but their absence from the azotemic group was not statistically significant (P = .15). 6/14 (43%) azotemic cats and 40/55 (73%) nonazotemic cats were seropositive (P = .06). CONCLUSIONS AND CLINICAL IMPORTANCE: Feline morbillivirus was detected in cats in the UK for the First time. However, there was no association between virus prevalence or seropositivity and azotemic CKD. These data do not support the hypothesis that FeMV infection is associated with the development of azotemic CKD in cats in the UK. PMID- 29572952 TI - A Genealogy of Animal Diseases and Social Anthropology (1870-2000). AB - Culling, vaccinating, and monitoring animals are the three main techniques used in contemporary veterinary public health to manage animal diseases that can be transmitted to humans. Each technique is underpinned by different ontological understandings of how microbes figure in relations between humans and animals. Therefore, animal diseases are not only a question for an applied anthropology but also involve the theoretical core of the discipline: that is, understanding how social causality emerges out of physical causality. To defend this argument, the article describes what Herbert Spencer wrote about foot-and-mouth disease; what William Robertson Smith thought about sacrifice in the context of bovine tuberculosis; how Emile Durkheim took vaccination for smallpox as a metaphor for the pathologies of the social; and what Claude Levi-Strauss wrote about mad cow disease. The conceptions of the social in the writing of these four authors are analyzed through their understanding of the risk of transmission of animal diseases to humans, moving from prevention to precaution to preparedness. PMID- 29572951 TI - Effect of heat treatment on 4'-O-methylpyridoxine (MPN) content in Ginkgo biloba seed extract solution. AB - BACKGROUND: A vitamin B6 derivative, 4'-O-methylpyridoxine (MPN), is responsible for food poisoning by Ginkgo biloba seeds. In this study, we investigate the content of pyridoxine and MPN in MPN standard solution and G. biloba seed extract solution upon heat treatment in order to evaluate the reduction of toxic components in G. biloba seed by such treatment. RESULTS: Heat treatment was conducted at 90-150 degrees C for 0-60 min, and all samples were adjusted to the same concentration of 1 g L-1 . The MPN content decreased to 994.92-563.69 mg kg 1 for MPN standard solution and to 371.56-76.84 mg kg-1 for G. biloba seed extract solution, and in both cases decreased even further with increasing heat treatment time. However, in all samples, except for the 90 degrees C heat treatment group, the pyridoxine content in MPN standard solution increased with increasing heat temperature and time; in addition, the extract solution showed a similar tendency. This may be the result of thermal degradation of MPN into pyridoxine. CONCLUSION: We can expect to improve the utilization of functional food materials by applying suitable heat treatment conditions and decreasing the MPN content of the G. biloba seed.

AB - BACKGROUND: In this study, we aimed to establish a versatile in vivo model of prostate cancer, which adequately mimics intraprostatic tumor growth, and the natural routes of metastatic spread. In addition, we analyzed the capability of high-resolution ultrasonography (hrUS), in vivo micro-CT (MUCT), and 9.4T MRI to monitor tumor growth and the development of lymph node metastases. METHODS: A total of 5 * 105 VCaP cells or 5 * 105 cells of LuCaP136- or LuCaP147 spheroids were injected into the prostate of male CB17-SCID mice (n = 8 for each cell type). During 12 weeks of follow-up, orthotopic tumor growth, and metastatic spread were monitored by repetitive serum-PSA measurements and imaging studies including hrUS, MUCT, and 9.4T MRI. At autopsy, primary tumors and metastases were harvested and examined by histology and immunohistochemistry (CK5, CK8, AMACR, AR, Ki67, ERG, and PSA). From imaging results and PSA-measurements, tumor volume doubling time, tumor-specific growth rate, and PSA-density were calculated. RESULTS: All 24 mice developed orthotopic tumors. The tumor growth could be reliably monitored by a combination of hrUS, MUCT, MRI, and serum-PSA measurements. In most animals, lymph node metastases could be detected after 12 weeks, which could also be well visualized by hrUS, and MRI. Immunohistochemistry showed positive signals for CK8, AMACR, and AR in all xenograft types. CK5 was negative in VCaP- and focally positive in LuCaP136- and LuCaP147-xenografts. ERG was positive in VCaP- and negative in LuCaP136- and LuCaP147-xenografts. Tumor volume doubling times and tumor-specific growth rates were 21.2 days and 3.9 %/day for VCaP-, 27.6 days and 3.1 %/day for LuCaP136- and 16.2 days and 4.5 %/day for LuCaP147-xenografts, respectively. PSA-densities were 433.9 ng/mL per milliliter tumor for VCaP-, 6.5 ng/mL per milliliter tumor for LuCaP136-, and 11.2 ng/mL per milliliter tumor for LuCaP147-xenografts. CONCLUSIONS: By using different monolayer and 3D spheroid cell cultures in an orthotopic xenograft model, we established an innovative, versatile in vivo model of prostate cancer, which enables the study of both intraprostatic tumor growth as well as metastatic spread to regional lymph nodes. HrUS and MRI are feasible tools to monitor tumor growth and the development of lymph node metastases while these cannot be visualized by MUCT. PMID- 29572954 TI - Water requirements of canine athletes during multi-day exercise. AB - BACKGROUND: Exercise increases water requirements, but there is little information regarding water loss in dogs performing multi-day exercise OBJECTIVES: Quantify the daily water turnover of working dogs during multi-day exercise and establish the suitability of SC administration of tracer to determine water turnover. ANIMALS: Fifteen privately owned Labrador retrievers trained for explosive detection duties and 16 privately owned Alaskan Huskies conditioned for mid-distance racing. METHODS: All dogs received 0.3 g D2 O/kg body weight by IV infusion, gavage, or SC injection before the start of a multi day exercise challenge. Explosive detection dogs conducted 5 days of simulated off-leash explosive detection activity. Alaskan sled dogs completed a mid distance stage race totaling 222 km in 2 days. Total body water (TBW) and daily water turnover were calculated using both indicator dilution and elimination regression techniques. RESULTS: Total body water (% of body weight) varied from 60% +/- 8.6% in minimally conditioned Labrador retrievers to 74% +/- 4.5% in highly conditioned Labrador retrievers. Daily water turnover was as high as 45% of TBW during exercise in cold conditions. There was no effect of sex or speed on daily water turnover. There was good agreement between results calculated using the indicator dilution approach and those calculated using a semilog linear regression approach when indicator isotope was administered IV or SC. CONCLUSIONS AND CLINICAL IMPORTANCE: Water requirements are influenced primarily by the amount of work done. SC administration of isotope-labeled water offers a simple and accurate alternative method for metabolic studies. PMID- 29572955 TI - High Imminent Vertebral Fracture Risk in Subjects With COPD With a Prevalent or Incident Vertebral Fracture. AB - Subjects with chronic obstructive pulmonary disease (COPD) have an increased risk of vertebral fractures (VFs); however, VF incidence is largely unknown. Therefore, the aim of our study was to determine the incidence of new and/or worsening VF in subjects with COPD. Smokers and subjects with COPD (GOLD II-IV) from the ECLIPSE study with complete set of chest CT scans (baseline and 1- and 3 year follow-up) to evaluate vertebrae T1 down to L1 were included. If a VF was diagnosed on the last scan, detailed VF assessment of the previous scans was performed. VFs were scored according to the method of Genant as mild, moderate, or severe. Main outcome measure was the cumulative incidence of new and/or worsening VF at subject level, within 1 and 3 years. Of 1239 subjects (mean age 61 years, 757 males [61%], 999 subjects with COPD), 253 (20.5%) had >=1 prevalent VF. The cumulative incidence of VFs was 10.1% within 1 year and 24.0% within 3 years. After adjustment for age, sex, body mass index (BMI), pack-years, and smoking status, prevalence and incidence were similar between smokers and COPD GOLD stages. Within 1 year, 29.2% of the subjects with a prevalent VF had an incident VF, compared with 5.1% in absence of prevalent VF (hazard ratio [HR] = 5.1; 95% confidence interval [CI] 3.6-7.4) and 58.5% versus 15.0% within 3 years (HR = 3.6; 95% CI 2.9-4.6). The incidence of VF was higher with increasing number and severity of prevalent VFs. Among subjects having an incident VF within the first year, 57.3% had a subsequent VF within the next 2 years. In this study, more than half of the smokers and subjects with COPD with a prevalent VF or an incident VF within the first year sustained a subsequent VF within 3 years. The 3 year risk was even higher in the presence of multiple or severe prevalent VFs. (c) 2018 The Authors. Journal of Bone and Mineral Research Published by Wiley Periodicals Inc. PMID- 29572956 TI - Trends in time-loss injuries during the 2011-2016 South African Rugby Youth Weeks. AB - Youth rugby is a popular sport in South Africa (SA) with a high injury incidence. The annual SA Rugby Youth Week tournaments attract the top age-group players in the country providing a sample of players for reliable injury surveillance. The aim of the study was to analyze the changes in time-loss injury rates at the SA Rugby Youth Week tournaments between 2011 and 2016, differences between age groups, and to investigate associated injury risk factors. All confirmed time loss injuries at the 4 age-group tournaments (under-13, under-16, and 2 under-18) from 2011 to 2016 were recorded. Injury incidence densities (IID) for years, tournaments, and injury risk factors were calculated and Poisson regression analyses were performed to determine differences. Time-loss injuries (n = 494) were reported over 24 240 exposure hours, with an overall IID of 20.4 (18.6-22.2) injuries per 1000 player hours. The year 2013 had a significantly lower IID compared to 2011. Injury risk decreased with increasing age; under-13 and under 16 had significantly higher IID compared to under-18 Craven Week. Tackling was the phase of play at highest risk, with an IID of 7.4 (6.3-8.5) injuries per 1000 player hours. Central/peripheral nervous system (CNS/PNS) and, therefore, the head/neck were the most commonly occurring injuries/location injured. In conclusion, within the SA Rugby tournament structure, the older players had a decreased rate of injury. The tackle event was still the phase of play with the highest injury incidence regardless of age. This increase in incidence is largely due to an increase in CNS/PNS injuries. PMID- 29572957 TI - Optometric infection control guidelines assessing patients with methicillin resistant Staphylococcus aureus. AB - The purpose of this scoping review was to present the state of research regarding optometric infection control guidelines for the assessment of patients with methicillin-resistant Staphylococcus aureus (MRSA) and to identify any areas requiring further research. Twelve articles were carefully chosen for review. Data extracted included information regarding appropriate handwashing methods (five articles), indications for use of personal protective equipment (one article), management of surfaces that come in contact with an MRSA-infected person (three articles), recommendations for patient appointment scheduling/seating (three articles) and suggestions for staff training (three articles). The results of the review demonstrated that there exist many gaps in the literature regarding comprehensive optometric-specific infection control guidelines. Further research regarding appropriate handwashing methods, equipment disinfection techniques, extent and breadth of staff training and indications for use of personal protective equipment is required to better understand what precautions must be taken in an optometric setting when encountering patients with MRSA. PMID- 29572958 TI - Pharmacokinetics and efficacy of intravenous famotidine in adult cattle. AB - BACKGROUND: Abomasal ulceration is recognized in neonatal and adult cattle, but research regarding treatment is limited. Histamine-2 receptor antagonists (H2 RA), such as famotidine, are used clinically with little evidence-based research about efficacy in adult cattle. HYPOTHESIS AND OBJECTIVES: Intravenous famotidine administered at 0.4 mg/kg will increase the pH of abomasal outflow digesta compared to saline control in adult cattle. The objectives were to assess the effect of famotidine, administered as a single dose and as multiple doses, on abomasal outflow fluid pH in adult cattle. A third objective was to describe the pharmacokinetic parameters of IV famotidine in cattle. ANIMALS: Four clinically healthy adult Angus-cross steers previously fitted with duodenal cannulae placed orad to the biliary and pancreatic ducts. METHODS: Randomized, 2-way cross-over clinical trial. Steers received IV famotidine (0.4 mg/kg) as a single and 3-dose regimen (every 8 hours) versus saline control. Blood for analysis of serum famotidine concentration was collected intermittently for 12 hours, and abomasal outflow fluid pH was measured at intervals for a 24-hour period. After a 34-hour washout period, the opposite treatments were administered and the sampling repeated. RESULTS: Abomasal outflow fluid pH was higher in steers treated with famotidine for up to 4 hours after a single dose but the effect decreased with subsequent doses. The median (range) elimination half-life was 3.33 (3.21-3.54) hours. CONCLUSIONS AND CLINICAL IMPORTANCE: Famotidine may be useful for treatment or prevention of abomasal ulceration in adult cattle, but the duration of effect may decrease with time. PMID- 29572959 TI - A highly decoupled transmit-receive array design with triangular elements at 7T. AB - PURPOSE: Transmit arrays are essential tools for various RF shimming or parallel excitation techniques at 7T. Here we present an array design with triangular coils to improve diversity in the B1 profiles in the longitudinal (z) direction and allow for next-nearest neighbor decoupling. METHODS: Two cylindrical 8 channel arrays having the same length and diameter, 1 of triangular coils and the other of rectangular coils, were constructed and compared in phantom imaging experiments using measures of excitation distribution for a variety of RF shim settings and geometry factor maps for different accelerations on different planes. RESULTS: Coupling between elements was -20 dB or better for all triangular coil pairs, but worse than -12 dB for several of the rectangular coil pairs. Both coils could produce adequate shims on a central transverse plane, but the same shim produced worse results off center for the triangular coil array than for the rectangular coil array. Compared to the rectangular coil array, the maximum geometry factor for the triangular coil array was reduced by a factor of 13.1 when using a 2-fold acceleration in the z-direction. CONCLUSION: An array design with triangular coils provides effective decoupling mechanisms for nearest and next-nearest neighboring elements, as well as diversity in B1 profiles along the z-direction, although this also means that individual slices must be shimmed separately. This design is well suited for parallel transmit applications while also having high receive sensitivity. PMID- 29572960 TI - The demosponge Halichondria (Halichondria) panicea (Pallas, 1766) as a novel source of biosurfactant-producing bacteria. AB - The Mediterranean sponge Halichondria (Halichondria) panicea was explored as a novel matrix for the isolation of biosurfactant-producing bacteria. A total of 38 (out of 56) isolates gave a good response to the employed screening tests (e.g., stable emulsion detection, surface tension measurement, hemolytic activity, and blue agar plate assay) and were selected for further analyses. The thin layer chromatography revealed a possible glucidic composition of biosurfactants. Most promising strains, i.e., those able to produce stable emulsion with percentage higher than 30% and yellow spots on TLC plates, were affiliated to the genera Pseudovibrio, Acinetobacter, and Bacillus. The biosurfactant production by two isolates (i.e., Acinetobacter sp. SpN134 and Pseudovibrio sp. SpE85) was evaluated under different culture conditions, in terms of temperature, NaCl concentration, and pH. Surface tension reduction ability was more stable than the emulsification, and resulted differently influenced by salinity, temperature, and pH. Acinetobacter sp. SpN134 resulted particularly efficient and competitive if compared with other well-known biosurfactant producers. Data suggest that sponges may represent a promising matrix for the isolation of biosurfactant-producing bacteria, reinforcing the growing interest towards filter-feeding organisms as underexplored sources of specialized bacteria. PMID- 29572961 TI - Maintenance of Serum Ionized Calcium During Exercise Attenuates Parathyroid Hormone and Bone Resorption Responses. AB - Exercise can cause a decrease in serum ionized calcium (iCa) and increases in parathyroid hormone (PTH) and bone resorption. We used a novel intravenous iCa clamp technique to determine whether preventing a decline in serum iCa during exercise prevents increases in PTH and carboxy-terminal collagen crosslinks (CTX). Eleven cycling-trained men (aged 18 to 45 years) underwent two identical 60-min cycling bouts with infusion of Ca gluconate or saline. Blood sampling for iCa, total calcium (tCa), PTH, CTX, and procollagen type 1 amino-terminal propeptide (P1NP) occurred before, during, and for 4 hours after exercise; results are presented as unadjusted and adjusted for plasma volume shifts (denoted with subscript ADJ). iCa decreased during exercise with saline infusion (p = 0.01 at 60 min) and this was prevented by Ca infusion (interaction, p < 0.007); there were abrupt decreases in Ca content (iCaADJ and tCaADJ ) in the first 15 min of exercise under both conditions. PTH and CTX were increased at the end of exercise (both p < 0.01) on the saline day, and markedly attenuated (-65% and -71%; both p < 0.001) by Ca. CTX remained elevated for 4 hours after exercise on the saline day (p < 0.001), despite the return of PTH to baseline by 1 hour after exercise. P1NP increased in response to exercise (p < 0.001), with no difference between conditions, but the increase in P1NPADJ was not significant. Results for PTHADJ and CTXADJ were similar to unadjusted results. These findings demonstrate that bone resorption is stimulated early in exercise to defend serum iCa. Vascular Ca content decreased early in exercise, but neither the reason why this occurred, nor the fate of Ca, are known. The results suggest that the exercise-induced increase in PTH had an acute catabolic effect on bone. Future research should determine whether the increase in PTH generates an anabolic response that occurs more than 4 hours after exercise. (c) 2018 American Society for Bone and Mineral Research. PMID- 29572962 TI - Unique Bond Breaking in Crystalline Phase Change Materials and the Quest for Metavalent Bonding. AB - Laser-assisted field evaporation is studied in a large number of compounds, including amorphous and crystalline phase change materials employing atom probe tomography. This study reveals significant differences in field evaporation between amorphous and crystalline phase change materials. High probabilities for multiple events with more than a single ion detected per laser pulse are only found for crystalline phase change materials. The specifics of this unusual field evaporation are unlike any other mechanism shown previously to lead to high probabilities of multiple events. On the contrary, amorphous phase change materials as well as other covalently bonded compounds and metals possess much lower probabilities for multiple events. Hence, laser-assisted field evaporation in amorphous and crystalline phase change materials reveals striking differences in bond rupture. This is indicative for pronounced differences in bonding. These findings imply that the bonding mechanism in crystalline phase change materials differs substantially from conventional bonding mechanisms such as metallic, ionic, and covalent bonding. Instead, the data reported here confirm a recently developed conjecture, namely that metavalent bonding is a novel bonding mechanism besides those mentioned previously. PMID- 29572963 TI - Local treatment for metastatic prostate cancer: A systematic review. AB - The potential oncological benefit for radical treatment in the setting of oligometastatic prostate cancer has been under investigation and is frequently discussed. We carried out a systematic review of English language articles using the Medline database (January 2000 to May 2017) to identify studies reporting local treatment in men with metastatic prostate cancer at diagnosis. Primary end points were oncological outcomes, such as cancer-specific and overall mortality. Secondary end-points were non-oncological outcomes, such as complications, operating room time, blood loss or length of hospital stay. Two independent authors reviewed and extracted all search results. Overall, 18 studies reporting on local treatment in metastatic prostate cancer patients were identified (14 original articles, three brief correspondences and one letter to the editor). All of them were retrospective; one partly included prospective data. All studies addressed oncological outcomes, 16 compared local treatment with no-local treatment and 14 adjusted for confounders using multivariable regression models. All but one study concluded a survival benefit for local treatment in the metastatic setting. Due to heterogeneity of available data, a representative meta analysis could not be carried out. Five studies reported non-oncological outcomes. Although local treatment in metastatic prostate cancer appears to be feasible, its oncological effect remains unclear due to high susceptibility of available studies to significant selection bias. PMID- 29572964 TI - Nonnoble-Metal-Based Plasmonic Nanomaterials: Recent Advances and Future Perspectives. AB - The application scope of plasmonic nanostructures is rapidly expanding to keep pace with the ongoing development of various scientific findings and emerging technologies. However, most plasmonic nanostructures heavily depend on rare, expensive, and extensively studied noble metals such as Au and Ag, with the limited choice of elements hindering their broad and practical applications in a wide spectral range. Therefore, abundant and inexpensive nonnoble metals have attracted attention as new plasmonic nanomaterial components, allowing these nonnoble-metal-based materials to be used in areas such as photocatalysis, sensing, nanoantennas, metamaterials, and magnetoplasmonics with new compositions, structures, and properties. Furthermore, the use of nonnoble metal hybrids results in newly emerging or synergistic properties not observed from single-metal component systems. Here, the synthetic strategies and recent advances in nonnoble-metal-based plasmonic nanostructures comprising Cu, Al, Mg, In, Ga, Pb, Ni, Co, Fe, and related hybrids are highlighted, and a discussion and perspectives in their synthesis, properties, applications, and challenges are presented. PMID- 29572965 TI - Nanomaterial-Based Plasmon-Enhanced Infrared Spectroscopy. AB - Surface-enhanced infrared absorption (SEIRA) has attracted increasing attention due to the potential of infrared spectroscopy in applications such as molecular trace sensing of solids, polymers, and proteins, specifically fueled by recent substantial developments in infrared plasmonic materials and engineered nanostructures. Here, the significant progress achieved in the past decades is reviewed, along with the current state of the art of SEIRA. In particular, the plasmonic properties of a variety of nanomaterials are discussed (e.g., metals, semiconductors, and graphene) along with their use in the design of efficient SEIRA configurations. To conclude, perspectives on potential applications, including single-molecule detection and in vivo bioassays, are presented.

AB - This study demonstrates the supramolecular chirality control of a conjugated polymer via solvent polarity. We designed and synthesized a chiral polyfluorene thiophene copolymer having two different chiral side chains at the 9-position of the fluorene unit. Chiral cyclic and alkyl ethers with different polarities were selected as the chiral side chains. The sign of the circular dichroism spectra in the visible wavelength region was affected by the solvent system, resulting from the change of supramolecular structure. The estimation of the solubility parameter revealed that the solubility difference of the side chains contributed to the change of the circular dichroism sign, which was also observed in spin coated films prepared from good solvents having different polarities. PMID- 29572967 TI - In chemico skin sensitization risk assessment of botanical ingredients. AB - Skin sensitization risk assessment of botanical ingredients is necessary for consumers' protection and occupational hazard identification. There are currently very few available alternative methods that can assist in the evaluation of complex mixtures. Chemical methods can provide essential information in a timely manner and thus help to reduce the need for in vivo testing, and they can complement and facilitate targeted in vitro assays. In the present work, the applicability of the high-throughput screening with dansyl cysteamine (DCYA) method for the systematic evaluation of skin sensitization of complex botanicals was explored. Botanical ingredients of four unrelated plant species were obtained and tested with the high-throughput fluorescence method at three concentrations. To illustrate the minimal matrix effects of the tested extracts on the developed method, the least DCYA-reactive extract (Rosa canina) was spiked with known sensitizers at different concentrations. The data obtained from the four plant extracts and the spiking experiments with known sensitizers, suggest that the high-throughput screening-DCYA method can be successfully applied for estimating the skin sensitization potential of complex botanical matrices. This is the first report of an attempt to develop a versatile in chemico method for the rapid detection of reactive skin sensitizers in complex botanical extracts, which could complement the battery of existing validated, non-animal methods.

AB - The development of biomaterial-based immune niches that can modulate immunosuppressive factors in tumor microenvironment (TME) will be a key technology for improving current cancer immunotherapy. Here, implantable, engineered 3D porous scaffolds are designed to generate synergistic action between myeloid-derived suppressor cell (MDSC)-depleting agents, which can accommodate the establishment of a permissive immunogenic microenvironment to counteract tumor-induced immunosuppression, and cancer vaccines consisting of whole tumor lysates and nanogel-based adjuvants, which can generate tumor antigen specific T cell responses. The local peritumoral implantation of the synthetic immune niche (termed immuneCare-DISC, iCD) as a postsurgical treatment in an advanced-stage primary 4T1 breast tumor model generates systemic antitumor immunity and prevents tumor recurrence at the surgical site as well as the migration of residual tumor cells into the lungs, resulting in 100% survival. These therapeutic outcomes are achieved through the inhibition of immunosuppressive MDSCs in tumors and spleens by releasing gemcitabine and recruitment/activation of dendritic cells, enhanced population of CD4+ and CD8+ T cells, and increased IFN-gamma production by cancer vaccines from the iCD. This combined spatiotemporal modulation of tumor-derived immunosuppression and vaccine induced immune stimulation through the iCD is expected to provide an immune niche for prevention of postoperative tumor recurrence and metastasis.

AB - Little is known about the prevalence and associated of morbidity of tendon problems. With only severe cases of tendon problems missing games, players that have their training and performance impacted are not captured by traditional injury surveillance. The aim of this study was to report the prevalence of Achilles and patellar tendon problems in elite male Australian football players using the Oslo Sports Trauma Research Centre (OSTRC) overuse questionnaire, compared to a time-loss definition. Male athletes from 12 professional Australian football teams were invited to complete a monthly questionnaire over a 9-month period in the 2016 pre- and competitive season. The OSTRC overuse injury questionnaire was used to measure the prevalence and severity of Achilles and patellar tendon symptoms and was compared to traditional match-loss statistics. A total of 441 participants were included. Of all participants, 21.5% (95% CI: 17.9 25.6) and 25.2% (95% CI 21.3-29.4) reported Achilles or patellar tendon problems during the season, respectively. Based on the traditional match-loss definition, a combined 4.1% of participants missed games due to either Achilles or patellar tendon injury. A greater average monthly prevalence was observed during the pre season compared to the competitive season. Achilles and patellar tendon problems are prevalent in elite male Australian football players. These injuries are not adequately captured using a traditional match-loss definition. Prevention of these injuries may be best targeted during the off- and pre-season due to higher prevalence of symptoms during the pre-season compared to during the competitive season. PMID- 29572970 TI - A Universal Strategy for Intimately Coupled Carbon Nanosheets/MoM Nanocrystals (M = P, S, C, and O) Hierarchical Hollow Nanospheres for Hydrogen Evolution Catalysis and Sodium-Ion Storage. AB - Intimately coupled carbon/transition-metal-based hierarchical nanostructures are one of most interesting electrode materials for boosting energy conversion and storage applications owing to the strong synergistic effect between the two components and appealing structural stability. Herein, a universal method is reported for making hierarchical hollow carbon nanospheres (HCSs) with intimately coupled ultrathin carbon nanosheets and Mo-based nanocrystals. The in situ and confined reaction of the synthetic strategy can not only allow the aggregation of the nanocrystals to be impeded, but also endows extremely intimate coupled interaction between the conductive carbon nanosheets and the nanocrystals MoM (M = P, S, C and O). As a proof of concept, the as-prepared MoP/C HCSs exhibit extraordinary hydrogen evolution reaction electrocatalytic activity with small overpotential and robust durability in both acidic and alkaline solutions. In addition, the unique sheet-on-sheet MoS2 /C HCSs as an anode demonstrate high capacity, great rate capabilities, and long-term cycles for sodium-ion batteries (SIBs). The capacity can be maintained at 410 mA h g-1 even after 1000 cycles even at a high current density of 4 A g-1 , one of the best reported values for MoS2 -based electrode materials for SIBs. The present work highlights the importance of designing and fabricating functional strongly coupled hybrid materials for enhancing energy conversion and storage applications. PMID- 29572971 TI - Droplet Microarrays: From Surface Patterning to High-Throughput Applications. AB - High-throughput screening of live cells and chemical reactions in isolated droplets is an important and growing method in areas ranging from studies of gene functions and the search for new drug candidates, to performing combinatorial chemical reactions. Compared with microfluidics and well plates, the facile fabrication, high density, and open structure endow droplet microarrays on planar surfaces with great potential in the development of next-generation miniaturized platforms for high-throughput applications. Surfaces with special wettability have served as substrates to generate and/or address droplets microarrays. Here, the formation of droplet microarrays with designed geometry on chemically prepatterned surfaces is briefly described and some of the newer and emerging applications of these microarrays that are currently being explored are highlighted. Next, some of the available technologies used to add (bio-)chemical libraries to each droplet in parallel are introduced. Current challenges and future prospects that would benefit from using such droplet microarrays are also discussed. PMID- 29572972 TI - Contact-Engineered Electrical Properties of MoS2 Field-Effect Transistors via Selectively Deposited Thiol-Molecules. AB - Although 2D molybdenum disulfide (MoS2 ) has gained much attention due to its unique electrical and optical properties, the limited electrical contact to 2D semiconductors still impedes the realization of high-performance 2D MoS2 -based devices. In this regard, many studies have been conducted to improve the carrier injection properties by inserting functional paths, such as graphene or hexagonal boron nitride, between the electrodes and 2D semiconductors. The reported strategies, however, require relatively time-consuming and low-yield transfer processes on sub-micrometer MoS2 flakes. Here, a simple contact-engineering method is suggested, introducing chemically adsorbed thiol-molecules as thin tunneling barriers between the metal electrodes and MoS2 channels. The selectively deposited thiol-molecules via the vapor-deposition process provide additional tunneling paths at the contact regions, improving the carrier injection properties with lower activation energies in MoS2 field-effect transistors. Additionally, by inserting thiol-molecules at the only one contact region, asymmetric carrier-injection is feasible depending on the temperature and gate bias. PMID- 29572973 TI - Textile Display for Electronic and Brain-Interfaced Communications. AB - Textile displays are poised to revolutionize current electronic devices, and reshape the future of electronics and related fields such as biomedicine and soft robotics. However, they remain unavailable due to the difficulty of directly constructing electroluminescent devices onto the textile-like substrate to really display desired programmable patterns. Here, a novel textile display is developed from continuous electroluminescent fibers made by a one-step extrusion process. The resulting displaying textile is flexible, stretchable, three-dimensionally twistable, conformable to arbitrarily curved skins, and breathable, and can dynamically display a series of desired patterns, making it useful for bioinspired electronics, soft robotics, and electroluminescent skins, among other applications. It is demonstrated that these displaying textiles can also communicate with a computer and mouse brain for smart display and camouflage applications. This work may open up a new direction for the integration of wearable electroluminescent devices with the human body, providing new and promising communication platforms. PMID- 29572974 TI - Impact of remnant vital tissue after locoregional treatment and liver transplant in hepatocellular cancer patients, a multicentre cohort study. AB - The role of pathological findings after locoregional treatments as predictors of hepatocellular cancer recurrence after liver transplantation has been poorly addressed. The aim of the study was to identify the role of remnant vital tissue (RVT) of the target lesion in predicting hepatocellular cancer recurrence. Two hundred and seventy-six patients firstly undergoing locoregional treatment and then transplanted between January 2010 and December 2015 in four European Transplant Centres (i.e. Rome Tor Vergata, Birmingham, Brussels and Ancona) were enrolled in the study to investigate the role of pathological response at upfront locoregional treatment. At multivariable Cox regression analysis, RVT >=2 cm was a strong independent risk factor for post-LT recurrence (HR = 5.6; P < 0.0001). Five-year disease-free survival rates were 60.8%, 80.9% and 95.0% in patients presenting a RVT >=2 cm vs. 0.1-1.9 vs. no RVT, respectively. When only Milan Criteria-IN patients were analysed, similar results were reported, with 5-year disease-free survival rates of 58.1%, 79.0% and 94.0% in patients presenting a RVT >=2 cm vs. 0.1-1.9 vs. no RVT, respectively. RVT is an important determinant of tumour recurrence after liver transplantation performed for hepatocellular cancer. Its discriminative power looks to be evident also in a Milan-IN setting, suggesting to more liberally use locoregional treatments also in these patients. PMID- 29572975 TI - Effects of oxidative stress induced by high dosage of dietary iron ingested on intestinal damage and caecal microbiota in Chinese Yellow broilers. AB - The objective of this trial was to test the effects of oxidative stress induced by a high dosage of dietary iron on intestinal lesion and the microbiological compositions in caecum in Chinese Yellow broilers. A total of 450 1-day-old male chicks were randomly allotted into three groups. Supplemental iron (0, 700 and 1,400 mg/kg) was added to the basal diet resulting in three treatments containing 245, 908 and 1,651 mg/kg Fe (measured value) in diet respectively. Each treatment consisted of six replicate pens with 25 birds per pen. Jejunal enterocyte ultrastructure was observed by transmission electron microscopy. The results showed that a high dosage of dietary iron induced oxidative stress in broilers. Dilated endoplasmic reticulum (ER), autophagosome formation of jejunal enterocytes and decreased villi were caused by this oxidative stress. Compared to the control, concentration of the malondialdehyde (MDA) in jejunal mucosa in the 908 and 1,651 mg/kg Fe groups increased by 180% (p < .01) and 155% respectively (p < .01); activity of copper-zinc superoxide dismutase (Cu/ZnSOD) increased in jejunum (p < .01); and the concentration of plasma reduced glutathione (GSH) decreased by 34.9% (p < .01) in birds fed 1,651 mg/kg Fe. Gene expression of nuclear factor, erythroid-derived 2-like 2 (Nrf2) and zonula occludens-1 (ZO-1), in the higher dietary Fe groups was enhanced (p < .05). Species of microbial flora in caecum increased caused by oxidative stress. The PCR-DGGE (denaturing gradient gel electrophoresis) dendrograms revealed different microbiota (65% similarity coefficient) between the control and iron-supplemented groups (p < .05). These data suggest high dosage of iron supplement in feed diet can induce oxidative stress in Chinese Yellow broilers, and composition of microbiota in the caecum changed. It implied there should be no addition of excess iron when formulating diets in Chinese Yellow broilers.

PMID- 29572976 TI - The effect of Nordic hamstring exercise training volume on biceps femoris long head architectural adaptation. AB - The aim of this study was to determine the time course of architectural adaptations in the biceps femoris long head (BFLH ) following high or low volume eccentric training. Twenty recreationally active males completed a two week standardized period of eccentric Nordic hamstring exercise (NHE) training, followed by four weeks of high (n = 10) or low volume (n = 10) training. Eccentric strength was assessed pre- and post intervention and following detraining. Architecture was assessed weekly during training and after two and four weeks of detraining. After six weeks of training, BFLH fascicles increased significantly in the high (23% +/- 7%, P < .001, d = 2.87) and low volume (24% +/ 4%, P < .001, d = 3.46) groups, but reversed following two weeks of detraining (high volume: -17% +/- 5%, P < .001, d = -2.04; low volume: -15% +/- 3%, P < .001, d = -2.56) after completing the intervention. Both groups increased eccentric strength after six weeks of training (high volume: 28% +/- 20%, P = .009, d = 1.55; low volume: 34% +/- 14%, P < .001, d = 2.09) and saw no change in strength following a four week period of detraining (high volume: -7% +/- 7%, P = .97, d = -0.31; low volume: -2% +/- 5%, P = .99, d = -0.20). Both low and high volume NHE training stimulate increases in BFLH fascicle length and eccentric knee flexor strength. Architectural adaptations reverted to baseline levels within two weeks after ceasing training, but eccentric strength was maintained for at least four weeks. These observations provide novel insight into the effects of training volume and detraining on BFLH architecture and may provide guidance for the implementation of NHE programs. PMID- 29572978 TI - Ectopic epithelial cell clusters in salmonid intestine are associated with inflammation. AB - An epizootic incidence of intestinal adenocarcinomas was reported in brood fish of Atlantic salmon (Salmo salar L.) in 2009. The condition was associated with a specific diet inducing enteritis and morphological changes. Here, two field trials of fish up to slaughter size were initiated. In Trial 1, two different feed recipes were used. Feed I was predominantly based on marine ingredients, whereas plant ingredients were limited to soy protein concentrate and wheat. Feed II was lower in fishmeal and without soya protein, which was substituted with plant proteins from other sources. In Trial 2, a commercial feed (Feed III) was included. No macroscopic tumours were observed in 300 fish (Trial 1). At the end of both trials, samples from five different segments of the gastrointestinal tract of a total of 39 fish were investigated with morphological methods. Here, we show the presence of ectopic proliferating epithelial cells only occurring in inflamed intestine and predominantly in the second segment of the mid-intestine. Presence of ectopic epithelial cells in submucosal inflammatory foci may indicate early stages in tumorigenesis, but other possibilities such as proliferative enteric disorders cannot be excluded. Together with inflammation, carcinogenesis should be a focus of investigation in future feed trials. PMID- 29572979 TI - Functional, RF-Trilayer Sensors for Tooth-Mounted, Wireless Monitoring of the Oral Cavity and Food Consumption. AB - Wearable devices have emerged as powerful tools for personalized healthcare in spite of some challenges that limit their widespread applicability as continuous monitors of physiological information. Here, a materials-based strategy to add utility to traditional dielectric sensors by developing a conformal radiofrequency (RF) construct composed of an active layer encapsulated between two reverse-facing split ring resonators is applied. These small (down to 2 mm * 2 mm) passive dielectric sensors possess enhanced sensitivity and can be further augmented by functionalization of this interlayer material. Demonstrator devices are shown where the interlayer is: (i) a porous silk film, and (ii) a modified PNIPAM hydrogel that swells with pH or temperature. In vivo use is demonstrated by adhesion of the device on tooth enamel to detect foods during human ingestion. Such sensors can be easily multiplexed and yield data-rich temporal information during the diffusion of analytes within the trilayer structure. This format could be extended to a suite of interlayer materials for sensing devices of added use and specificity.

AB - This concept article focuses on the rapid growth of intracellular chemistry dedicated to the integration of small-molecule metal catalysts with living cells and organisms. Although biological systems contain a plethora of biomolecules that can deactivate inorganic species, researchers have shown that small-molecule metal catalysts could be engineered to operate in heterogeneous aqueous environments. Synthetic intracellular reactions have recently been reported for olefin hydrogenation, hydrolysis/oxidative cleavage, azide-alkyne cycloaddition, allylcarbamate cleavage, C-C bond cross coupling, and transfer hydrogenation. Other promising targets for new biocompatible reaction discovery will also be discussed, with a special emphasis on how such innovations could lead to the development of novel technologies and chemical tools.

AB - INTRODUCTION: The objective of this study was to estimate mortality and survival in a large cohort of myasthenia gravis (MG) patients from Belgrade, Serbia, during the period 1979-2008. METHODS: Data for all patients with MG were collected from hospital records and the Belgrade MG Registry. RESULTS: Within the 30-year study period, death occurred in 107 (20%) of 562 patients with MG, with MG-related fatality below 2%. The average MG mortality rate was 1.76 per 1,000,000 population (1.26/1,000,000 women, 2.45/1,000,000 men). A statistically significant increase was recorded for the average standardized mortality rate for all patients (P < 0.01). The mean survival from disease onset was 34.3 +/- 2.0 years. Significantly shorter survival was observed in men compared with women and in patients older than 50 years compared with younger ones (P < 0.01). DISCUSSION: We observed long survival and low frequency of MG-related fatalities but increasing average standardized mortality rate, most notably in older men with MG. Muscle Nerve 58: 708-712, 2018. PMID- 29572982 TI - An update on the biophysical character of the human eukaryotic elongation factor 1 beta: Perspectives from interaction with elongation factor 1 gamma. AB - The beta-subunit of the human eukaryotic elongation factor 1 complex (heEF1beta) plays a central role in the elongation step in eukaryotic protein biosynthesis, which essentially involves interaction with the alpha- and gamma-subunits (eEF1gamma). To biophysically characterize heEF1beta, we constructed 3 Escherichia coli expression vector systems for recombinant expression of the full length (FL-heEF1beta), N-terminus (NT-heEF1beta), and the C-terminus (CT heEF1beta) regions of the protein. Our results suggest that heEF1beta is predominantly alpha-helical and possesses an accessible hydrophobic cavity in the CT-heEF1beta. Both FL-heEF1beta and NT-heEF1beta form dimers of size 62 and 30 kDa, respectively, but the CT-heEF1beta is monomeric. FL-heEF1beta interacts with the N-terminus glutathione transferase-like domain of heEF1gamma (NT-heEF1gamma) to form a 195-kDa complex or a 230-kDa complex in the presence of oxidized glutathione. On the other hand, NT-heEF1beta forms a 170-kDa complex with NT heEF1gamma and a high molecular weight aggregate of size greater than 670 kDa. Surface plasmon resonance analysis confirmed that (by fitting the Langmuir 1:1 model) FL-heEF1beta associated with monomeric or dimeric NT-heEF1gamma at a rapid rate and slowly dissociated, suggesting strong functional affinity (KD = 9.6 nM for monomeric or 11.3 nM for dimeric NT-heEF1gamma). We postulate that the N terminus region of heEF1beta may be responsible for its dimerization and the C terminus region of heEF1beta modulates the formation of an ordered heEF1beta gamma oligomer, a structure that may be essential in the elongation step of eukaryotic protein biosynthesis. PMID- 29572983 TI - Halogen, Chalcogen, and Pnicogen Bonding Involving Hypervalent Atoms. AB - The additional substituents arising from hypervalency present a number of complicating issues for the formation of noncovalent bonds. The XF5 molecule (X=Cl, Br, I) was allowed to form a halogen bond with NH3 as the base. Hypervalent chalcogen bonding is examined by way of YF4 and YF6 (Y=S, Se, Te), and ZF5 (Z=P, As, Sb) is used to model pnicogen bonding. Pnicogen bonds are particularly strong, with interaction energies approaching 50 kcal mol-1 , and also involve wholesale rearrangement from trigonal bipyramidal in the monomer to square pyramidal in the complex, subject to a large deformation energy. YF4 chalcogen bonding is also strong, and like pnicogen bonding, is enhanced by a heavier central atom. XF5 halogen bond energies are roughly 9 kcal mol-1 , and display a unique sensitivity to the identity of the X atom. The crowded octahedral structure of YF6 permits only very weak interactions. As the F atoms of SeF6 are replaced progressively by H, a chalcogen bond appears in combination with SeH???N and NH???F H-bonds. The strongest such chalcogen bond appears in SeF3 H3 ???NH3 , with a binding energy of 7 kcal mol-1 , wherein the base is located in the H3 face of the Lewis acid. Results are discussed in the context of the way in which the positions and intensities of sigma-holes are influenced by the locations of substituents and lone electron pairs.

AB - A novel manganese(III)-mediated oxidative cyclization of readily accessible 1,2,3 trisubstituted indoles is described. This unprecedented method enabled the efficient construction of a complex polycyclic scaffold bearing a spiro-indoline motif and a lactone moiety in one step.

AB - 29 Si magic angle spinning (MAS) NMR spectroscopy has been applied for the first time to the structural analysis of ancient glass samples obtained from archaeological excavations. The results show that it is possible to establish the distribution of Si environments in ancient glass by 29 Si MAS NMR, so long as the concentrations of magnetic impurities, such as Mn and Fe oxides, are low. In general, good agreement has been obtained with compositions determined by means of electron probe microanalysis. In addition, the 29 Si MAS NMR data reveal structural differences between glasses manufactured at separate ancient sites. PMID- 29572986 TI - Dynamics of formation and morphological features of neutrophil extracellular traps formed under the influence of opsonized Staphylococcus aureus. AB - In the process of performing their protective functions, neutrophils can form neutrophil extracellular traps (NETs), consisting of DNA in combination with enzymes and histones. The aim of the study was to determine the dynamics of the formation of NETs under the influence of opsonized Staphylococcus aureus and to determine the morphological features of their development in real time by atomic force microscopy. It was found that the maximum formation of NETs was observed after 3 hours of co-incubation of neutrophils and opsonized S. aureus. For the first time, the atomic force microscopy method revealed that, at first, large blocks of parallel DNA helices are formed, which then spread in waves, and only then their bifurcation and separation can be observed. Some of the strands formed are covered by a shell, which subsequently completely disappears. Enzymes and histones become clearly visible only after 140 to 150 minutes of observation. The DNA helixes move toward the opsonized S. aureus. After NET formation, the cell remains on the substrate only in the form of traces of focal adhesion. This, and the fact that the maximum amount of NETs is formed after 3 hours of co-incubation with opsonized S. aureus, suggests that the formation of NETs follows the classical mechanism. The study of the dynamics of formation and the microstructure of NETs makes it possible to estimate the time frame for the implementation of this protective mechanism of the human body when performing the compensatory inflammatory reaction. PMID- 29572987 TI - Chemical and Absorption Signatures of Xiao Chai Hu Tang. AB - RATIONALE: Xiao Chai Hu Tang (XCHT, Sho-saiko-to in Japanese) is a well-known medicine formula used in Asia for centuries. However, the quality control and the absorption of XCHT components are the major remaining concerns.. The study was to develop a sensitive and robust method to characterize the chemical components in XCHT and evaluate their absorptions. METHODS: An ultra-high pressure liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF MS/MS) was used to identify the compounds in XCHT. The Caco-2 cell culture model was employed to determine the absorption of the identified components. RESULTS: The results showed that 109 compounds were identified including organic acids, flavonoids, saikosaponins, ginsenosides, licoricesaponins and gingerols. The absorption study showed that among those identified, 33 compounds have decent absorption permerbilities ranging from 1.46 +/- 0.24*10-7 to 3.10+/-0.61*10-5 cm/sec. These compounds were classified as classes II and IV in the biopharmaceutical classification system (BCS). CONCLUSIONS: These identified compounds could be used to characterize quality of XCHT and those absorbed compounds with decent permreabiliteis are the potential active components in XCHT. Future pharmacodynamics studies should focus on these absorbed compounds.

AB - The diverse functionalities of large N-heteroacenes continue to be developed in terms of their strategic synthesis and application in the organic electronic field. Here, we report a novel large stable pyrene-containing N-heteroacene with ten linearly-annulated rings in one row. Remarkably, it exhibited excellent tri state resistive memory property, which held great promise to achieve ultrahigh density data storage. To the best of our knowledge, it is the first demonstration of organic multistate memory device based on large N-heteroacene (n>=10), which provides guidelines for designing more proof-of-concept larger N-heteroacene based memory electronics. PMID- 29572989 TI - Development of a multi-functional concurrent assay using weak cation-exchange solid-phase extraction (WCX-SPE) and reconstitution with a diluted sample aliquot for anti-doping analysis. AB - RATIONALE: In addition to the development of adequate screening methods for multiple compounds, the World Anti-Doping Agency (WADA) requires anti-doping laboratories to analyze prohibited substances and their metabolites from various classes. This task presents a difficult challenge for all agencies and interests involved in the field of doping control. METHODS: A screening method is reported in which hybrid sample preparation was performed using a combination of weak cation-exchange solid-phase extraction (WCX-SPE) and the 'Dilute and Shoot' strategy in order to take advantage of both the methodologies. Target substances were extracted using a WCX cartridge and reconstituted with a diluted sample aliquot that included 20% of an untreated urine sample. The target substances were further analyzed by high-performance liquid chromatography/triple quadrupole mass spectrometry (LC/MS). RESULTS: The SPE procedure was optimized using a cartridge-washing step, elution conditions, and elution volume. The cartridge washing step, which was performed using 10% methanol, improved the overall recovery of target substances. Since the recovery was observed to vary according to the pH of the eluting solution, we applied an elution step using both an acid and a basic organic solvent to achieve complementary recovery. Reconstitution of the diluted aliquot sample was performed to recover the polar substances. CONCLUSIONS: The method was validated and applied to real samples in accordance with the external quality assessment scheme of WADA and to the previously reported samples that had provided positive test results. This novel method using hybrid sample preparation and LC/MS could be useful to screen multiple classes of the 264 targeted substances in anti-doping analysis.

AB - PURPOSE: To obviate online slice-by-slice RF shim optimization and reduce B1+ mapping requirements for patient-specific RF shimming in high-field magnetic resonance imaging. THEORY AND METHODS: RF Shim Prediction by Iteratively Projected Ridge Regression (PIPRR) predicts patient-specific, SAR-efficient RF shims with a machine learning approach that merges learning with training shim design. To evaluate it, a set of B1+ maps was simulated for 100 human heads for a 24-element coil at 7T. Features were derived from tissue masks and the DC Fourier coefficients of the coils' B1+ maps in each slice, which were used for kernelized ridge regression prediction of SAR-efficient RF shim weights. Predicted shims were compared to directly designed shims, circularly polarized mode, and nearest neighbor shims predicted using the same features. RESULTS: PIPRR predictions had 87% and 13% lower B1+ coefficients of variation compared to circularly polarized mode and nearest-neighbor shims, respectively, and achieved homogeneity and SAR similar to that of directly designed shims. Predictions were calculated in 4.92 ms on average. CONCLUSION: PIPRR predicted uniform, SAR-efficient RF shims, and could save a large amount of B1+ mapping and computation time in RF-shimmed ultra high field magnetic resonance imaging.

AB - Luminescent lanthanide-containing compounds have a lot of stimulating applications. However, the fine-tuning of the optical properties of multi-nuclear lanthanide edifices is still a big challenge. We report here the coordination self-assembly of a group of bright luminescent lanthanide organic polyhedra (LOPs) with record high emission quantum yields, by using two fully-conjugated ligands featuring the triazole-pyridine-amido (tpa) chelating moiety, easily accessible from the "Click" reaction. The self-assembled LOPs are characterized by NMR spectroscopy, high-resolution ESI-TOF-MS, and X-ray crystallography. Interestingly, inter-metal energy transfer (ET) is confirmed on the mixed lanthanide polyhedral molecules, though the metal centers are separated nearly 2 nm apart. A feasible ratiometric luminescent thermometer, with work range from cryogenic to physiological temperatures, has been demonstrated with the mixed Eu/Tb LOPs. We envisage these molecular-level bright luminescent LOPs have great application potential in displaying, labelling/imaging, up-conversion materials etc. PMID- 29572992 TI - Therapeutic Nanoreactors as In Vivo Nanoplatforms for Cancer Therapy. AB - Therapeutic nanoreactors have been proposed as nanoplatforms to treat diseases through in situ production of therapeutic agents. When this treatment strategy is applied in cancer therapy, it can efficiently produce highly toxic anticancer drugs in situ from low-toxic prodrugs or some biomolecules in tumor tissues, which can maximize the therapeutic efficacy with a significantly low systemic toxicity. An ideal therapeutic nanoreactor can provide the reaction space, protect the loaded fragile catalysts, target the desired pathological site, and be selectively activated. In this minireview, we highlight the recent advances concerning the applications of therapeutic nanoreactors as in vivo nanoplatforms particularly in cancer therapy. Herein, the therapeutic nanoreactors are discussed on the basis of treatment strategies and various nanoparticles. Specifically, the treatment strategies of nanoreactors including single enzyme, single enzyme with chemodrugs, and multienzymes, as well as varying types of engineered nanoparticle-loaded active catalysts, primarily including liposomes, polymersomes, polymeric micelles, inorganic nanoparticles, and metal-organic framework (MOF) architectures, are documented and briefly discussed. Finally, we elucidate the current challenges to be addressed toward further development and translation into clinical applications of these therapeutic nanoreactors in cancer therapy. PMID- 29572993 TI - Hierarchical Mesoporous Organosilica-Silica Core-Shell Nanoparticles Capable of Controlled Fungicide Release. AB - A new class of hierarchically structured mesoporous silica core-shell nanoparticles (HSMSCSNs) with a periodic mesoporous organosilica (PMO) core and a mesoporous silica (MS) shell is reported. The applied one-pot, two-step strategy allows rational control over the core/shell chemical composition, topology, and pore/particle size, simply by adjusting the reaction conditions in the presence of cetyltrimethylammonium bromide (CTAB) as structure-directing agent under basic conditions. The spherical, ethylene- or methylene-bridged PMO cores feature hexagonal (p6mm) or cage-like cubic symmetry (Pm3? n) depending on the organosilica precursor. The hexagonal MS shell was obtained by n-hexane-induced controlled hydrolysis of TEOS followed by directional co-assembly/condensation of silicate/CTAB composites at the PMO cores. The HSMSCSNs feature a hierarchical pore structure with pore diameters of about 2.7 and 5.6 nm in the core and shell domains, respectively. The core sizes and shell thicknesses are adjustable in the ranges of 90-275 and 15-50 nm, respectively, and the surface areas (max. 1300 m2 g-1 ) and pore volumes (max. 1.83 cm3 g-1 ) are among the highest reported for core-shell nanoparticles. The adsorption and controlled release of the fungicide propiconazole by the HSMSCSNs showed a three-stage release profile.

AB - BACKGROUND: Gastrointestinal symptoms are common in Parkinson's disease and frequently precede the development of motor impairments. Intestinal inflammation has been proposed as a driver of disease pathology, and evaluation of inflammatory mediators in stool could possibly identify valuable early-stage biomarkers. We measured immune- and angiogenesis-related proteins in human stool to examine inflammatory profiles associated with Parkinson's disease. METHODS: Stool samples and subjects' self-reported metadata were obtained from 156 individuals with Parkinson's disease and 110 without, including spouse and nonhousehold controls. Metadata were probed for disease-associated differences, and levels of 37 immune and angiogenesis factors in stool homogenates were measured by multiplexed immunoassay and compared across experimental groups. RESULTS: Parkinson's disease patients reported greater incidence of intestinal disease and digestive problems than controls. Direct comparison of levels of stool analytes in patients and controls revealed elevated vascular endothelial growth factor receptor 1, interleukin-1alpha, and CXCL8 in patients' stool. Paired comparison of patients and spouses suggested higher levels of multiple factors in patients, but this was complicated by sex differences. Sex, body mass index, a history of smoking, and use of probiotics were found to strongly influence levels of stool analytes. Multivariate analysis accounting for these and other potential confounders confirmed elevated levels of interleukin-1alpha and CXCL8 and also revealed increased interleukin-1beta and C-reactive protein in stool in Parkinson's disease. These differences were not dependent on subject age or disease duration. CONCLUSIONS: Levels of stool immune factors indicate that intestinal inflammation is present in patients with Parkinson's disease. (c) 2018 International Parkinson and Movement Disorder Society.

PMID- 29572996 TI - Synthesis and Characterization of Photothermal Osmium Carbolong Complexes. AB - Metallacycles with chelating polydentate conjugated-carbon chain ligands are called carbolong complexes, which are expected to have interesting properties. In this work, the preparation of 12-carbon carbolong complexes in which all of the coordinated atoms in the equatorial plane are carbon atoms was studied. With the help of the well-established mechanism, a new approach to prepare coplanar carbolong complexes bearing different organic functional groups was developed by adding different terminal alkynes in sequence. In the presence of HBF4 , these coplanar carbolong complexes were converted to eta3 -allyl osmapentalene derivatives, which can be produced directly from the reaction of cyclopropaosmapentalene 1 with terminal alkynes in the presence of AgBF4 under anhydrous conditions. This study offers a new route for the preparation of functional osmium carbolong complexes with excellent photothermal properties, which can be used to prepare photothermal materials.

AB - Floccularia luteovirens, an important edible mushroom widely distributed in the Qinghai-Tibet plateau, is ecologically important as an ectomycorrhizal fungus and can form the fairy ring. To explore the influence of F. luteovirens fairy ring on soil microbial communities, we compared the soil microbial communities in three different fairy ring zones (inside the fairy ring (IN); beneath the fairy ring (ON); and outside the fairy ring (OUT)). A total of 1.77 million bacterial reads and 1.59 million fungal reads were obtained. Moreover, sequence clustering yielded 519,613 (57,735 per sample) bacterial OTUs, and 513,204 (57,023 per sample) fungal OTUs representing. Microbial diversity was lower in samples from the ON zone compared with the other two zones. Mycorrhiza helper bacteria (MHB) such as Bradyrhizobium and Paenibacillus were more common in the ON zone, and we isolated four potential MHB from rhizosphere soil. Canonical correspondence analysis showed that the soil nutritional condition and physical changes caused by F. luteovirens shaped the microbial communities in the ON zone. This is the first report on the study of soil microbial diversity influenced by fairy ring F. luteovirens, and further studies need to be conducted to study the ecological function influenced by this species. PMID- 29572998 TI - Ligand-Based Storage of Protons and Electrons in Dihydrazonopyrrole Complexes of Nickel. AB - A newly developed dihydrazonopyrrole ligand and corresponding Ni complexes have been synthesized and thoroughly characterized. Electrochemical studies and chemical reactivity tests show that these complexes can reversibly store both electrons and protons, or equivalently H-atoms, via ligand-based events. The stored H-atom equivalent can be transferred to small molecules such as acetonitrile or oxygen. Furthermore, this series of complexes can adopt a variety of different coordination modes. In addition to one e- reactivity, the two e- electrophilic oxidation of phosphines is also demonstrated. Taken together, these results show that dihydrazonopyrrole complexes represent a geometrically and electronically flexible scaffold for controlling the flow of both electrons and protons.

AB - INTRODUCTION AND AIMS: As alcohol use has decreased among Finnish adolescents, we aim to assess: (i) time trends in alcohol use, heavy episodic drinking (HED) and potential explanatory variables among adolescents; (ii) the relationship between trends of explanatory variables and trends in alcohol use and HED; and (iii) which of the explanatory variables can account for the temporal change in alcohol use and HED. DESIGN AND METHODS: The analyses are based on European School Survey Project on Alcohol and Other Drugs data collected from 15- to 16-year-old Finnish adolescents in 1999, 2003, 2007, 2011 and 2015. RESULTS: The decline in alcohol use and HED among underage youth in Finland is associated with at least three factors: (i) obtaining alcohol has become more difficult; (ii) parents know better than before where their children spend their Friday nights; and (iii) the risk attached to going out with friends on drinking has decreased. DISCUSSION AND CONCLUSIONS: Formal policy measures and adults' attitudes have probably affected the availability of alcohol for adolescents, and thus they partly explain the decline in youth drinking. This decline coincides with the introduction of new digital technologies, new forms of interaction within families and peer groups, and more conscientious teenagers. All these changes are not necessarily causes of the decline but are part of a similar broader change in adolescents' lives. PMID- 29573001 TI - Cadaveric study validating in vitro monitoring techniques to measure the failure mechanism of glenoid implants against clinical CT. AB - Definite glenoid implant loosening is identifiable on radiographs, however, identifying early loosening still eludes clinicians. Methods to monitor glenoid loosening in vitro have not been validated to clinical imaging. This study investigates the correlation between in vitro measures and CT images. Ten cadaveric scapulae were implanted with a pegged glenoid implant and fatigue tested to failure. Each scapulae were cyclically loaded superiorly and CT scanned every 20,000 cycles until failure to monitor progressive radiolucent lines. Superior and inferior rim displacements were also measured. A finite element (FE) model of one scapula was used to analyze the interfacial stresses at the implant/cement and cement/bone interfaces. All ten implants failed inferiorly at the implant-cement interface, two also failed at the cement-bone interface inferiorly, and three showed superior failure. Failure occurred at of 80,966 +/- 53,729 (mean +/- SD) cycles. CT scans confirmed failure of the fixation, and in most cases, was observed either before or with visual failure. Significant correlations were found between inferior rim displacement, vertical head displacement and failure of the glenoid implant. The FE model showed peak tensile stresses inferiorly and high compressive stresses superiorly, corroborating experimental findings. In vitro monitoring methods correlated to failure progression in clinical CT images possibly indicating its capacity to detect loosening earlier for earlier clinical intervention if needed. Its use in detecting failure non-destructively for implant development and testing is also valuable. The study highlights failure at the implant-cement interface and early signs of failure are identifiable in CT images. (c) 2018 The Authors.

PMID- 29573002 TI - Unusually Long-Wavelength Emissions of Cyclopropanes: New Insight into C-C Bond Homolysis. AB - Bond homolysis (BHo) is a fundamental concept in chemical-bonding phenomena. To date, research studies on the BHo concept have provided crucial information for understanding the nature of chemical bonding and reactions. Two potential-energy minima, a sigma-bonding isomer and a singlet-diradical isomer, have been known to exist in carbon-carbon BHo. Herein, a third isomer, that is, a puckered singlet diradical exhibiting unstructured long-wavelength fluorescence beyond 460 nm, was first observed in the excited states of 1,4-diarylbicyclo[2.1.0]pentane derivatives. The careful selection of appropriate substituents in the bicyclic structures enabled direct spectral detection. State-of-the-art ab initio quantum chemical calculations quantitatively reproduced the experimental observations. This new finding provides new insight into carbon-carbon bond-breaking and forming processes. PMID- 29573003 TI - Phosphorescence Through Hindered Motion of Pure Organic Emitters. AB - This minireview deals with the phenomenon of room-temperature phosphorescence induced by aggregation or crystallisation. Recent achievements, as well as novel classes of these unique luminophores, are put in to focus. In this fashion, different compounds, which reveal delayed fluorescence or phosphorescence upon fixation in a crystal lattice or within aggregates are described. Furthermore, the photophysical properties, the origin of the long-lived triplet states, and the possible applications of these fascinating classes of molecules are also discussed. To conclude, a short overview about the state of art in the field of pure organic phosphors at room temperature is presented. PMID- 29573004 TI - RAD-seq linkage mapping and patterns of segregation distortion in sedges: meiosis as a driver of karyotypic evolution in organisms with holocentric chromosomes. AB - Meiotic drive, the class of meiotic mechanisms that drive unequal segregation of alleles among gametes, may be an important force in karyotype evolution. Its role in holocentric organisms, whose chromosomes lack localized centromeres, is poorly understood. We crossed two individuals of Carex scoparia (Cyperaceae) with different chromosome numbers (2n = 33II = 66 * 2n = 32II = 64) to obtain F1 individuals, which we then self-pollinated to obtain second-generation (F2) crosses. RAD-seq was performed for 191 individuals (including the parents, five F1 individuals and 184 F2 individuals). Our F2 linkage map based on stringent editing of the RAD-seq data set yielded 32 linkage groups. In the final map, 865 loci were located on a linkage map of 3966.99 cM (linkage groups ranged from 24.39 to 193.31 cM in length and contained 5-51 loci each). Three linkage groups exhibit more loci under segregation distortion than expected by chance; within linkage groups, loci exhibiting segregation distortion are clustered. This finding implicates meiotic drive in the segregation of chromosome variants, suggesting that selection of chromosome variants in meiosis may contribute to the establishment and fixation of chromosome variants in Carex, which is renowned for high chromosomal and species diversity. This is an important finding as previous studies demonstrate that chromosome divergence may play a key role in differentiation and speciation in Carex.

AB - BACKGROUND: Major pharyngeal defects after total pharyngolaryngectomy for hypopharyngeal squamous cell carcinoma (SCC) frequently demand reconstruction strategies that include myocutaneous pedicled flaps, such as the pectoralis major flap. METHODS: We retrospectively reviewed the clinical charts of 24 patients with hypopharyngeal SCC treated with Bocca's hemipharyngo-total laryngectomy (HPTL) at our Institution. RESULTS: Eighteen patients (80%) experienced no disease recurrence after primary surgery and were alive with no evidence of disease after a mean follow-up of 43 months. The 2-year overall survival (OS) and disease-specific survival (DSS) rates in our sample were 69% and 82%, respectively. CONCLUSION: Bocca's HPTL enables an immediate neopharyngeal reconstruction, and is indicated in selected patients with intermediate to advanced hypopharyngeal tumors. PMID- 29573006 TI - Ubiquitin-specific protease 4 is an endogenous negative regulator of metabolic dysfunctions in nonalcoholic fatty liver disease. AB - Nonalcoholic fatty liver disease (NAFLD), characterized by hepatic steatosis, insulin resistance and inflammation, poses a high risk of cardiometabolic disorders. Ubiquitin specific protease 4 (USP4), a deubiquitinating enzyme, is pivotally involved in regulating multiple inflammatory pathways; however, the role of USP4 in NAFLD is unknown. Here we report that USP4 expression was dramatically downregulated in the livers from NAFLD patients and different NAFLD mouse models induced by a high fat diet (HFD) or a genetic deficiency (ob/ob) as well as in palmitate-treated hepatocytes. Hepatocyte-specific USP4 depletion exacerbated hepatic steatosis, insulin resistance and inflammatory response in HFD-induced NAFLD mice. Conversely, hepatic USP4 overexpression notably alleviated the pathological alterations in two different NAFLD models. Mechanistically, hepatocyte USP4 directly bound to and deubiquitinated transforming growth factor-beta activated kinase 1 (TAK1), leading to a suppression of the activation of downstream NF-kappaB and JNK cascades, which in turn reversed the disruption of the IRS-AKT-GSK3beta signaling. In addition, USP4 TAK1 interaction and subsequent TAK1 deubiquitination were required for the amelioration of metabolic dysfunctions. Collectively, the present study provides the first evidence that USP4 functions as a pivotal suppressor in NAFLD and related metabolic disorders. This article is protected by copyright.

AB - AIM: To determine the variables that affect patients' perceptions about their readiness for discharge and to elucidate the effects of these perceptions on patient outcomes such as unplanned readmission to the hospital, emergency department visits and death within 30 days after discharge. BACKGROUND: In recent years, it has become even more important to assess patients' readiness for discharge as patients tend to be discharged more quickly. METHODS: For the determination of patients' self-assessment, the Readiness for Hospital Discharge Scale/Short Form was utilized. This 1-year prospective cohort study included 1,601 patients. Data were analysed using a chi-square test, Mann-Whitney U test, univariate logistic regression analysis and multiple logistic regression analysis. RESULTS: The results of multiple logistic regression analysis revealed that age, sex, marital status, educational status, presence of someone to help at home after discharge and length of stay were predictors of patients' readiness for hospital discharge. Furthermore, being unready for discharge increased the risk of 30 day unplanned readmission and 30 day death. CONCLUSIONS: Considering these predictors, patients' perceptions of readiness for discharge must be assessed before deciding to discharge them. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers can consider the predictors of patients' readiness for discharge, thus the risk of unplanned readmission and death may be reduced. PMID- 29573008 TI - Naphtho[1,2-b:5,6-b']dithiophene-Based Conjugated Polymers for Fullerene-Free Inverted Polymer Solar Cells. AB - Three novel copolymers based on zigzag naphthodithiophene (zNDT) with different aromatic rings as pi bridges and different core side substitutions are designed and synthesized (PzNDT-T-1,3-bis(4-(2-ethylhexyl)-thiophen-2-yl)-5,7-bis(2 ethylhexyl)benzo[1,2-c:4,5-c']-dithiophene-4,8-dione (BDD), PzNDT-TT-BDD, and PzNDTP-T-BDD, respectively). The 2D conjugation structure and molecular planarity of the polymers can be effectively altered through the modification of conjugated side chains and pi-bridges. These alterations contribute to the variation in energy levels, light absorption capacity, and morphology compatibility of the polymers. When blended with the nonfullerene acceptor (2,2'-[(4,4,9,9-tetrahexyl 4,9-dihydro-sindaceno[1,2-b:5,6-b']dithiophene-2,7-diyl)bis[methylidyne(3-oxo-1H indene-2,1(3H)-diylidene)]]bis-propanedinitrile) (IDIC), PzNDT-T-BDD exhibits the highest power conversion efficiency (PCE) of 9.72% among the three polymers. This result can be attributed to its superior crystallinity and more obvious face-on orientation in blending film. PzNDT-TT-BDD and PzNDTP-T-BDD present PCE values of 8.20% and 4.62%, respectively. The alteration of polymer structure, particularly the modification of conjugated side chains and pi-bridges, is an effective strategy for designing NDT-based polymers with high photovoltaic performance and potential applications in fullerene-free solar cells. PMID- 29573010 TI - Do public expenditures on health and families relate to alcohol abstaining in adolescents? Multilevel study of adolescents in 24 countries. AB - INTRODUCTION AND AIMS: Several European countries have observed an increase in the proportion of adolescents that abstain from drinking alcohol in the last decade. The reasons for this trend remain underexplored. We hypothesised that more generous government expenditures on health services and benefits to families with children relate to a positive trend in abstainers. DESIGN AND METHODS: We used data on 15-year-olds in four successive cycles of the World Health Organization Health Behaviour in School-aged Children study (2002 to 2014) in 24 North American and European countries (pooled n = 175 331). Generalised linear mixed-effects models were tested to analyse trends in alcohol abstinence and to investigate whether cross-country differences in these trends relate to public expenditures on health and families with children (in proportion to gross domestic product). RESULTS: Overall, we observed an increase in the proportion of abstainers from 21% in 2002 to 35% in 2014. An exception was Greece where abstaining had decreased from 20% to 15%. Similar results were found in boys and girls. The upward trend in abstinence related to larger government expenditures on health and families. DISCUSSIONS AND CONCLUSIONS: More generous expenditures on health services and family benefits relate to more adolescents abstaining from alcohol. PMID- 29573009 TI - A diffusion model-free framework with echo time dependence for free-water elimination and brain tissue microstructure characterization. AB - PURPOSE: The compartmental nature of brain tissue microstructure is typically studied by diffusion MRI, MR relaxometry or their correlation. Diffusion MRI relies on signal representations or biophysical models, while MR relaxometry and correlation studies are based on regularized inverse Laplace transforms (ILTs). Here we introduce a general framework for characterizing microstructure that does not depend on diffusion modeling and replaces ill-posed ILTs with blind source separation (BSS). This framework yields proton density, relaxation times, volume fractions, and signal disentanglement, allowing for separation of the free-water component. THEORY AND METHODS: Diffusion experiments repeated for several different echo times, contain entangled diffusion and relaxation compartmental information. These can be disentangled by BSS using a physically constrained nonnegative matrix factorization. RESULTS: Computer simulations, phantom studies, together with repeatability and reproducibility experiments demonstrated that BSS is capable of estimating proton density, compartmental volume fractions and transversal relaxations. In vivo results proved its potential to correct for free water contamination and to estimate tissue parameters. CONCLUSION: Formulation of the diffusion-relaxation dependence as a BSS problem introduces a new framework for studying microstructure compartmentalization, and a novel tool for free-water elimination. PMID- 29573011 TI - Is age of menarche among school girls related to breastfeeding during infancy? AB - OBJECTIVES: Breastfeeding has been linked to various disease conditions in adulthood. Age of menarche has been proposed to be an intermediary factor on the life-course path to these disease conditions, but the link between breastfeeding and age of menarche remains under debate. This study aimed to investigate the association between age of menarche and breastfeeding during infancy. METHODS: A cross-sectional study was conducted in which 775 female high school students were randomly selected from private and public high schools in all provinces in Kuwait. Data on age of menarche were collected by self-administered questionnaires from the students, while data on breastfeeding were collected from their mothers through telephone interviews. Multiple linear regression was used to investigate the association between breastfeeding and age of menarche after adjusting for potential confounders. RESULTS: Of the study group 496 mothers responded to the telephone interview. Duration of breastfeeding was not significantly associated with age of menarche before or after adjusting for potential confounders (P = .279 and P = .124 for crude and fully adjusted model, respectively). Similarly, no significant association was found between type of breastfeeding during the first four months of life and age of menarche before or after adjusting for potential confounders (P = .949 and P = .398 for crude and fully adjusted model, respectively). CONCLUSION: No significant association was found between age of menarche and breastfeeding during infancy, which may suggest that the link between breastfeeding and disease conditions in adulthood is not necessarily mediated through age of menarche. PMID- 29573012 TI - Telehealth-based model of care redesign to facilitate local fitting and management of patients with a spinal fracture requiring a thoracic lumbar sacral orthosis in rural hospitals in New South Wales. AB - OBJECTIVE: To develop and implement a telehealth-based model of care for spinal fractures requiring management with thoracic lumbar sacral orthoses that eliminates the need for transfer to a metropolitan tertiary referral hospital. DESIGN: Pre-post design observational study evaluating model of care implementation. SETTING: Rural referral hospitals in a large NSW region covering metropolitan, rural and remote hospitals. PARTICIPANTS: Patients presenting with a thoracic or lumbar spine fracture requiring thoracic lumbar sacral orthoses management and rural clinicians caring for them. OUTCOME MEASURES: Number of patients managed in rural hospitals without transfer to a metropolitan tertiary referral hospital; length of stay and related cost efficiencies; clinicians' perceived skills, knowledge and confidence levels. RESULTS: Model of care was implemented with clinical and system governance processes; and educational workshops across eight rural hospitals. A total of 81 patients managed in rural hospitals under this model between July 2013 and June 2016 without transfer were included in this study. Mean length of stay reduced from nine to four days. Hospital transfers were eliminated from the patient journey, totalling 24 324 km. Workshops were attended by 71 clinicians from nine rural hospitals and survey findings indicated a significant increase in staff knowledge, skill and confidence post education. Cost efficiencies were gained by eliminating 162 inter hospital transfers and 405 patient bed days. CONCLUSION: This model has streamlined patient journeys and reduced transfers and travel, enabling rural clinicians to provide specialised services in local communities and facilitating timely evidence-based care in local communities without any adverse events. PMID- 29573013 TI - Policy to practice: Investment in transitioning new graduate nurses to the workplace. AB - AIM: To analyse nurses' perceptions of the impact of an extended transition programme on key dimensions of care delivery 1-6 years after graduation. The dimensions included decision-making, communication, care management, system integration and commitment. BACKGROUND: Health care employers in Ontario, Canada, can apply for government funding to support an extended transition programme for new graduate nurses that includes orientation and mentorship. METHODS: A cross sectional study design was used. Nurses who participated in the transition programme were compared with nurses who did not. A survey was administered to a convenience sample of 2369 nurses. RESULTS: There were statistically significant differences between the two groups. Nurses in the transition programme had higher mean scores on the key dimensions of care delivery. Results were confirmed when controlling for length of time since graduation. CONCLUSION: Extended transition benefits new graduate nurses. It has a lasting effect over time and impacts key dimensions of care delivery. It can also enhance workforce integration and reduce turnover. IMPLICATIONS FOR NURSING MANAGEMENT: Responding to the needs of new graduate nurses has potential long-term advantages for health care organisations and can influence both quality and delivery of care. PMID- 29573014 TI - A modified Continuous Quality Improvement approach to improve culturally and socially inclusive care within rural health services. AB - BACKGROUND: The sickest Australians are often those belonging to non-privileged groups, including Indigenous Australians, gay, lesbian, bisexual, transsexual, intersex and queer people, people from culturally and linguistically diverse backgrounds, socioeconomically disadvantaged groups, and people with disabilities and low English literacy. These consumers are not always engaged by, or included within, mainstream health services, particularly in rural Australia where health services are limited in number and tend to be generalist in nature. OBJECTIVE: The aim of this study was to present a new approach for improving the sociocultural inclusivity of mainstream, generalist, rural, health care organisations. DESIGN: This approach combines a modified Continuous Quality Improvement framework with Participatory Action Research principles and Foucault's concepts of power, discourse and resistance to develop a change process that deconstructs the power relations that currently exclude marginalised rural health consumers from mainstream health services. It sets up processes for continuous learning and consumer responsiveness. RESULTS: The approach proposed could provide a Continuous Quality Improvement process for creating more inclusive mainstream health institutions and fostering better engagement with many marginalised groups in rural communities to improve their access to health care. CONCLUSION: The approach to improving cultural inclusion in mainstream rural health services presented in this article builds on existing initiatives. This approach focuses on engaging on-the-ground staff in the need for change and preparing the service for genuine community consultation and responsive change. It is currently being trialled and evaluated. PMID- 29573015 TI - A balanced approach to falls prevention: Application in the real world. AB - BACKGROUND: Falls place a heavy burden on the health system, impacting on an individual's quality of life, often resulting in a fear of falling, reduction in independence and at times admission to residential care. This study aimed to determine health professionals' confidence in discussing falls prevention strategies, topics discussed and the barriers and enablers to falls prevention discussions with clients aged 60 years and over. METHOD: A cross-sectional self complete online survey was undertaken with a sample of health professionals (n = 191) who had engaged in the services of the Stay On Your Feet(r) programs delivered by the Injury Matters in Western Australia (WA). RESULTS: The majority of participants were physiotherapists (25.7%), registered nurses (17.8%) and occupational therapists (11%) located in metropolitan (56%) and regional (44%) WA. Most health professionals (80.2%) were "highly" confident discussing falls prevention strategies. Discussion of falls prevention included the benefits of strength and balance exercises (83%), eating a healthy diet (78.7%), regular eyesight checks (64.5%), reviewing medications (54.8%) and exposure to sunlight (50.3%). The main enablers to falls prevention were knowledge (89.7%), skills to identify (77.7%) and implement (66.3%) falls prevention strategies, and access to printed resources (74.9%), while the main barrier was appointment times (14.6%). CONCLUSION: Health professionals' indicated that they are confident in discussing falls prevention strategies, and although a range of falls prevention strategies were discussed, limited attention was directed at the pharmacists' review of medications, eyesight checks and increasing vitamin D levels. SO WHAT?: Health professionals are discussing falls prevention strategies with their clients. A more multifaceted approach should be encouraged with an emphasis on all prevention strategies. PMID- 29573016 TI - Depressive symptoms, social anxiety, and perceived neck function in patients with head and neck cancer. AB - BACKGROUND: This study examined the relationships of depressive symptoms and social anxiety with perceived neck function in patients treated for head and neck cancer. METHODS: Depressive symptoms, social anxiety, and perceived neck-related function were measured at baseline, posttreatment, every 6 weeks thereafter for 1 year after the end of treatment, and at 15 and 18 months posttreatment. Group based trajectory modeling was used to generate clusters of patients with similar baseline and trajectories of perceived neck-related function after head and neck cancer treatment. RESULTS: Participants included 83 subjects who had completed at least 1 follow-up assessment. Three clusters of longitudinal patterns in neck disability were identified: none/mild, moderate, and severe. Significant associations were found between membership in the neck disability index trajectories and membership in the longitudinal patterns of depressive symptoms and social anxiety. CONCLUSION: Impaired physical function and psychological distress are intertwined for patients with head and neck cancer long after completing treatment. PMID- 29573017 TI - Constructing health capital in ecological systems: A qualitative evaluation of community-based health workshops in the refugee community. AB - Refugee communities face numerous health and mental health concerns both during and after resettlement. Health issues, already deteriorated by chronic poverty, malnutrition and poor living conditions, are exacerbated by acculturative challenges, such as cultural and language barriers, stigma, and lack of resources and information. Since such needs in refugee communities affect both individual and collective capacity, it is important to consider policy environment and socioecological contexts for cultural adjustment and community resources for navigating systems, rather than individual health behaviours and communication skills only. To expand our understanding of health promotion capacity and resources, a broad and context-dependent concept will be necessary. Adopting a concept of health capital, this study aims to explore the impact of community based health workshops, while expanding and redefining the framework in the context of health promotion efforts for the refugee community in resettlement. As part of community-based participatory research, this qualitative study conducted seven focus group discussions (FGDs) with 22 Bhutanese refugees in 2014. Using a hybrid thematic analysis, themes emerged from the FGD data were organised and categorised into health capitals in ecological systems. The participants reported enhanced confidence and capacity for health promotion at individual, family and community levels. Given the interdependent coping and lifestyles of refugee communities, impacts on the participants' interactions and relations with family and community were significant, which emphasises the importance of assessment of interventions beyond an individualistic approach. The findings of this study underscore the vital role of varied forms of health capital in promoting health in the refugee community and connecting members to needed health resources and information. Health capital is an old and yet still new concept with a great potential to broaden our understanding of health resources by elaborating the impacts and interactions in individuals, family and community for health promotion.

AB - AIMS: The main goal of the study was to apply and analyse a moderated participatory small-group procedure with registered nurses, which aims at the development and implementation of measures to improve work organisation in hospital wards and nursing units. BACKGROUND: Participation in job redesign is an essential prerequisite of the successful implementation of improvement measures in nursing. METHODS: The study was carried out in a public hospital of maximum care in Germany. We selected 25 wards with the most critical reported exhaustion and general health and applied a series of moderated small-group sessions in which the registered nurses jointly identified deficits in their work organisation, developed improvement measures, and then implemented and assessed them. RESULTS: Registered nurses of 22 wards actively took part in the small group procedure. All nursing units jointly identified organisational deficits, developed possible improvement measures, and implemented them. The nursing teams then evaluated the implemented measures which were already assessable at the end of our research period; nearly all (99.0%) showed improvements, while 69.4% actually attained the desired goals. CONCLUSION: Participatory small-group activities may be successfully applied in hospital nursing in order to improve work organisation. IMPLICATIONS FOR NURSING MANAGEMENT: Participatory assessment and redesign of nurses' work organisation should be integrated into regular team meetings. The nursing management should actively support the implementation process. PMID- 29573019 TI - Patient and family description of receiving care in acuity adaptable care model. AB - AIM: To explore patient and family perspectives of hospital care in an acuity adaptable care model implemented in an urban, public safety-net hospital. BACKGROUND: Specialty care units result in reactionary bed management. Changes in acuity generate costly, disruptive, intra-hospital patient transfers, which negatively affect clinical outcomes while increasing nurse workload. The acuity adaptable care model is a universal bed model structured to support patients in one room while providing staff, equipment and other resources across varying levels of acuity. METHOD: Qualitative descriptive methods were used to analyse the narratives of a purposive sample of patients and family members about receiving care in an acuity adaptable care delivery model. RESULTS: Three content areas emerged from the narratives and were categorized as feeling safe, perceiving continuity of care and valuing family, which culminated in a sense of comfort and healing while in the hospital. CONCLUSION: By bringing care services to the patient instead of taking the patient to the services, the acuity adaptable care model facilitated a perception of a healing environment for patients and family members. IMPLICATIONS FOR NURSING MANAGEMENT: The acuity adaptable care model should be considered when hospital facilities are undergoing major renovation or replacement. PMID- 29573020 TI - Adolescents drink less: How, who and why? A review of the recent research literature. AB - ISSUES: Today's teenagers have been described as a sober generation and we asked: 'What is known about the recent decline in youth drinking?' APPROACH: A literature review (2005-2017). KEY FINDINGS: Research from wealthier parts of the world provides solid evidence of less alcohol use by youth since the millennium shift. Some studies show that this is reflected at all levels of consumption, but there are also indications that the heaviest drinkers have not reduced their drinking. The decrease is predominately seen in underage youth, and has been larger for boys than for girls in several countries. Teenagers across social strata drink less, but some disadvantaged subgroups have not followed the downward trend. Underage drinkers have apparently not become a more deviant group as the prevalence of drinking has dropped, indicating no hardening of the group. The major gap in the literature pertains to the issue of underlying driving forces. We found no evidence in support of the widespread assumption that the digital revolution has been of importance. A decline in parenting practices that are conductive to underage drinking has occurred in several countries, but studies examining whether these changes have contributed to less alcohol use by youth are almost non-existent. IMPLICATIONS: To inform alcohol policy and prevention, it is imperative to find out why teenage drinking has decreased in a fairly consistent way across numerous countries. CONCLUSION: Future research into the issue of falling prevalence rates of youth drinking should focus on possible explanatory factors at the population level rather than at the individual level. PMID- 29573021 TI - Manipulation of parental nutritional condition reveals competition among family members. AB - Parental care is thought to be costly, as it consumes time and energy. Such costs might be reduced in animal parents that raise their young on valuable food sources such as dung or carcasses, as parents are able to invest in self maintenance by feeding from the same resource. However, this might lower the nutritional value for other family members and, as a consequence, food competition might arise. To promote our understanding of the outcome of such competition, we manipulated the necessity of parents to feed from the resource. Using a full factorial design, we paired food-deprived or well-fed males with food-deprived or well-fed females of burying beetles, which are known to raise their young on vertebrate cadavers. We found that food-deprived parents consumed more of the carrion than those that were well-fed and this had a negative impact on other family members. However, the outcome of the competition depended on the sex of the parents, with females suffering when males fed more and offspring suffering when females fed more. Thus, family life involves selfish elements, as both parents remove resources for the purpose of self-maintenance. However, females show altruistic aspects, as they appear to restrict their food consumption for the benefit of their offspring when paired with a food-deprived male. Interestingly, males extend their stay with the brood when having faced food scarcity prior to reproduction, presumably to replenish their energy reserves. Our study therefore reveals that breeding on shared resources can promote family living, but also results in competition. PMID- 29573022 TI - Exploration of male urethral sphincter complex using diffusion tensor imaging (DTI)-based fiber-tracking. AB - BACKGROUND: Urinary incontinence is a major clinical problem arising primarily from age-related degenerative changes to the sphincter muscles. However, the precise anatomy of the normal male sphincter muscles has yet to be established. Diffusion tensor imaging (DTI) may offer a unique insight into muscle microstructure and fiber architecture. PURPOSE: To explore the anatomy of the urethral sphincter muscles pertinent to urinary continence function using DT-MRI. STUDY TYPE: Prospective cohort study. SUBJECTS: Eleven normal male subjects (mean age: 25.4 years); two subjects were scanned in three separate sessions to assess reproducibility. FIELD STRENGTH/SEQUENCE: 3T; using a diffusion-weighted spin echo planar sequence. ASSESSMENT: DT parameters including fractional anisotropy (FA), primary (lambda1 ), secondary (lambda2 ), and tertiary (lambda3 ) eigenvalues, Apparent diffusion coefficient and radial diffusivity were analyzed statistically, while tracked muscle fibers were assessed visually. STATISTICAL TESTS: Regional differences (sphincters and longitudinal muscle of the urethra) in the DTI indices were assessed by one-way analysis of variance. A Tukey post hoc test was used to identify significant differences between muscle regions. RESULTS: Two sphincter muscles, one proximal near the base of the bladder, corresponding to the lisso-sphincter, and the other distal to the end of the prostate corresponding to the rhabdo-sphincter, surrounding a central urethral muscle fiber bundle, were clearly identified. FA was higher and lambda3 lower in the proximal sphincter muscle compared to the central urethral muscle and the distal sphincter (P < 0.05). The average coefficient of variation ranged from 5 12% for the DTI indices. DATA CONCLUSION: Since DTI values are known to reflect underlying tissue microarchitecture, significant differences in DTI indices identified here between the muscles of the urethral complex may potentially arise from differences in tissue microarchitecture that may in turn be related to the specific function of the sphincter and other muscles.

AB - AIMS: To examine how nurse managers' leadership styles, and nurses' organisational commitment in Saudi Arabia relate. BACKGROUND: Effective leadership is influential in staff retention; however, recruiting and maintaining nurses is an increasing problem in Saudi Arabia. METHODS: Using a survey design, the Multifactor Leadership Questionnaire and the Organisational Commitment Questionnaire were distributed to a sample of 219 nurses and nurse managers from two hospitals in Saudi Arabia. RESULTS: Transformational leadership was the most dominant leadership style. After controlling for the influence of manager/staff status, nationality and hospitals, transformational leadership was the strongest contributor to organisational commitment. Perceptions of both transformational and transactional leadership styles, increased with age for nurse managers and nursing staff. CONCLUSION: Introducing the Full Range of Leadership model to the Saudi nursing workforce could help to prepare Saudi nurses for positions as nurse managers and leaders. IMPLICATIONS FOR NURSING MANAGEMENT: The study provides insight into the type of leadership that is best suited to the dynamic and changing health care system in Saudi Arabia. It is possible that transformational leaders could influence and induce positive changes in nursing. PMID- 29573024 TI - Barriers and facilitators to self-management of asthma in adolescents: An interview study to inform development of a novel intervention. AB - BACKGROUND AND OBJECTIVE: Despite literature that spans twenty years describing the barriers to asthma self-management in adolescents, successful, clinically based interventions to address this important issue are lacking. Given the limitations of some of the previous studies, we conducted a study that aimed to gain a broader insight into barriers and facilitators to self-management of asthma by adolescents, not just adherence to treatment, and triangulated their views with those of their parents and healthcare professionals. METHODS: Focus groups and interviews were conducted separately for 28 adolescents with asthma aged 12-18 years, 14 healthcare professionals and 12 parents. Focus groups and interviews were audio-recorded, and transcripts from each participant group were analysed separately using inductive thematic analysis. We triangulated the three perspectives by comparing themes that had emerged from each analysis. RESULTS: Adolescents', parents' and healthcare professionals' views were summarized into ten related themes that included forgetting and routines, knowledge, embarrassment and confidence, communication with healthcare professionals, triggers, support at school, apathy and taking responsibility. We found that adolescents, parents and healthcare professionals raised similar barriers and facilitators to self-management and our results provide further validation for previous studies. CONCLUSION AND CLINICAL RELEVANCE: Our study highlights that healthcare professionals may need to consider a range of psychological and contextual issues influencing adolescents' ability to effectively self-manage their asthma, in particular, how they implement treatment routines and the understanding that adolescents have of their condition and treatments. Crucially, healthcare professionals need to consider how this information is communicated and ensure they facilitate open, inclusive, two-way consultations. From this more comprehensive understanding, we have developed interventional strategies that healthcare professionals can utilize to empower adolescents to improve their asthma self-management. PMID- 29573025 TI - Should we look beyond Kt/V urea in assessing dialysis adequacy? AB - Since the advent of maintenance dialysis therapy, our interpretation of what adequate dialysis really is has broadened and become more controversial. This is not only due to our changing and aging dialysis population but also to our evolving knowledge base. As nephrologists, we strive to achieve both quality and (often) quantity of life for our patients and we feel reassured when we have a quantifiable marker to show for our efforts. However, we suggest that adequate dialysis reaches far beyond the realms of attaining a particular biochemical result. Dialysis adequacy should encompass a more comprehensive assessment of patient well-being. This metric could comprise quality of life and patient specified goals, sufficient small solute and middle molecule clearance, optimal blood pressure control, and effective bone-mineral balance, all in the context of minimizing mortality and morbidity, and a livable dialysis regimen for the patient. PMID- 29573027 TI - BRAFwild papillary thyroid carcinoma has two distinct mRNA expression patterns with different clinical behaviors. AB - BACKGROUND: Using a large set of genomic data from The Cancer Genome Atlas (TCGA), we classified BRAFwild papillary thyroid carcinomas (PTCs) into 2 subtypes with distinct molecular patterns and different clinical behaviors. We also suggested gene signatures (RAS-score) to predict molecular subtypes and clinical behaviors of BRAFwild PTC. METHOD: Integrated genomic analysis was done using all genomic data of PTC in TCGA data portal (https://tcga-data.nci.nih.gov) and cancer browser (https://genome-cancer.ucsc.edu). Using Gene Ontology and a logistic regression test, we selected gene signatures (RAS-score) and applied this prediction model to the validation cohort (GSE60542). RESULT: When we performed multiplatform genomic analysis, BRAFwild PTCs were divided into 2 molecular subtypes. Each subtype showed distinct molecular patterns and clinical behaviors. Gene signatures successfully predicted molecular subtype in another validation cohort. CONCLUSION: We found that BRAFwild PTCs were divided into 2 molecular subtypes and each subtype showed distinct molecular patterns, different activated pathways, and different clinical behaviors. PMID- 29573026 TI - Neural correlates of reduced depressive symptoms following cognitive training for chronic traumatic brain injury. AB - Depression is the most frequent comorbid psychiatric condition among individuals with traumatic brain injury (TBI). Yet, little is known about changes in the brain associated with reduced depressive symptoms following rehabilitation for TBI. We identified whether cognitive training alleviates comorbid depressive symptoms in chronic TBI (>6 months post-injury) as a secondary effect. Further, we elucidated neural correlates of alleviated depressive symptoms following cognitive training. A total of seventy-nine individuals with chronic TBI (53 depressed and 26 non-depressed individuals, measured using the Beck Depressive Inventory [BDI]), underwent either strategy- or information-based cognitive training in a small group for 8 weeks. We measured psychological functioning scores, cortical thickness, and resting-state functional connectivity (rsFC) for these individuals before training, immediately post-training, and 3 months post training. After confirming that changes in BDI scores were independent of training group affiliation, we identified that the depressive-symptoms group showed reductions in BDI scores over time relative to the non-depressed TBI controls (p < .01). Within the depressive-symptoms group, reduced BDI scores was associated with improvements in scores for post-traumatic stress disorder, TBI symptom awareness, and functional status (p < .00625), increases in cortical thickness in four regions within the right prefrontal cortex (pvertex < .01, pcluster <.05), and decreases in rsFC with each of these four prefrontal regions (pvertex < .01, pcluster < .0125). Overall, these findings suggest that cognitive training can reduce depressive symptoms in TBI even when the training does not directly target psychiatric symptoms. Importantly, cortical thickness and brain connectivity may offer promising neuroimaging markers of training induced improvement in mental health status in TBI.

PMID- 29573029 TI - Place of surgery in the management of post-operative chronic pain after placement of prosthetic material based on a series of 107 cases. AB - AIMS: The objective of this study was to evaluate the efficacy of surgical removal of prosthetic material, possibly combined with nerve release, on chronic postoperative pain following placement of prosthetic material. MATERIAL AND METHODS: Single-tertiary-centre study on 107 patients managed between November 2004 and April 2016 for removal of prosthetic material responsible for postoperative chronic pain: retropubic suburethral sling (n = 32), transobturator suburethral sling (n = 50), prolapse mesh (n = 16), and hernia mesh (n = 9). The primary endpoint was at least 50% reduction of pain evaluated by a pain numerical rating scale (NRS). RESULTS: The mean interval between the initial operation involving placement of prosthetic material and reoperation for removal of prosthetic material was 41.2 +/- 35.4 months. In all cases pain apperaed immediately following prosthetic material placement surgery. Pain presented neuropathic features in almost 30% of cases and was poorly systematized in more than one-half The mean follow-up of the study population was 8.4 +/- 10.3 months. The mean pain NRS score for the overall population was seven preoperatively and three at last follow-up. At least 50% reduction of the pain NRS score was observed 67% of cases at last follow-up. During follow-up, 45% of patients experienced relapse of the disorder for which the prosthetic material was initially placed with, in particular, a 62% recurrence rate of urinary incontinence after removal of transobturator suburethral tape. CONCLUSION: Surgical removal of prosthetic material to treat chronic postoperative pain, achieved global improvement of pain in about two-thirds of cases, but with a risk of recurrence of the initial disorders. PMID- 29573030 TI - Treatment course and its predictors in patients with somatoform disorders: A routine outcome monitoring study in secondary psychiatric care. AB - AIM: Somatoform disorders are common and often chronic. It would be helpful to distinguish those patients who are likely to have a positive treatment course from those who are likely to follow a negative course. Such studies of different somatoform disorders are scarce, especially in secondary psychiatric care. This study examined the 6-month treatment course of psychological, physical symptoms, and functioning, and its predictors in a naturalistic sample of secondary psychiatric care outpatients with somatoform disorders. METHOD: The present study used routine outcome monitoring data of patients with somatoform disorders regarding their 6-month treatment course of psychological and physical symptoms as well as functioning. The following patient groups were included: total group of somatoform disorders (N = 435), and undifferentiated somatoform disorder (N = 242), pain disorder (N = 102), body dysmorphic disorder (N = 51), and hypochondriasis (N = 40). Measures were Mini-International Neuropsychiatric Interview plus, Brief Symptom Inventory, Montgomery-Asberg Depression Rating Scale, Brief Anxiety Scale, Short Form Health Survey 36, and Physical Symptom Checklist (PSC). RESULTS: The study population generally showed high co morbidity, especially with anxiety and mood disorders. The PSC total score, body dysmorphic disorder, and hypochondriasis were significant predictors for the treatment course of symptoms (Brief Symptom Inventory), whereas the PSC total score was the only significant predictor for the course of functioning (Short Form Health Survey 36). CONCLUSION: Secondary psychiatric care outpatients with somatoform disorders showed high co-morbidity with anxiety and mood disorders, and an unfavourable 6-month course of both symptoms and functioning. Clinical implications are discussed, such as additional treatment of co-morbidity in somatoform disorders. PMID- 29573031 TI - A systematic review of adverse events of rifapentine and isoniazid compared to other treatments for latent tuberculosis infection. AB - PURPOSE: Tuberculosis (TB) remains a common cause of death globally. A regimen of 12 doses of isoniazid (INH) and rifapentine given once weekly (INH/RPT-3) has recently been recommended by the World Health Organization for the treatment of latent TB infection (LTBI). We aimed to determine whether the INH/RPT-3 regimen had similar or lesser rates of adverse events compared to other LTBI regimens, namely INH for 9 months, INH for 6 months, rifampin for 3 to 4 months, and rifampin plus INH for 3 to 4 months. METHODS: We searched MEDLINE, Embase, CENTRAL, PubMed, ICTRP, clinicaltrials.gov, and Canadian Agency for Drugs and Technologies in Health's Gray Matters Light for randomized, postmarketing, and comparative nonrandomized studies of patients with confirmed LTBI that reported the frequency of at least 1 adverse event of relevance for a regimen of interest. The search included studies published until March 2017. The frequencies of adverse events were extracted and are presented descriptively. RESULTS: Data from 23 randomized and 55 nonrandomized studies were included. Although inconsistent event reporting and high heterogeneity limited comparisons, the adverse event profile of INH/RPT-3 appeared generally favorable. Flu-like reactions were reported with an increased frequency and hepatotoxicity with a lower frequency than standard treatment. CONCLUSIONS: While INH/RPT-3 had an overall low frequency of adverse events compared to INH monotherapy, reporting of adverse events for many regimens was limited meaning results should be interpreted cautiously. Future studies of LTBI treatment would benefit from more complete collection and reporting of adverse events and more consistent definitions of hepatotoxicity. PMID- 29573032 TI - Visualizing the effects of metformin on tumor growth, vascularity, and metabolism in head and neck cancer. AB - BACKGROUND: The antidiabetic drug metformin (Met) is believed to inhibit tumor proliferation by altering the metabolism of cancer cells. In this study, we examined the effects of Met on tumor oxygenation, metabolism, and growth in head and neck squamous cell carcinoma (HNSCC) using non-invasive multimodal imaging. MATERIALS AND METHODS: Severe combined immunodeficient (SCID) mice bearing orthotopic FaDu HNSCC xenografts were treated with Met (200 mg/kg, ip) once daily for 5 days. Tumor oxygen saturation (%sO2 ) and hemoglobin concentration (HbT) were measured using photoacoustic imaging (PAI). Fluorescence imaging was employed to measure intratumoral uptake of 2-deoxyglucosone (2-DG) following Met treatment while magnetic resonance imaging (MRI) was utilized to measure tumor volume. Correlative immunostaining of tumor sections for markers of proliferation (Ki67) and vascularity (CD31) was also performed. RESULTS: At 5 days post-Met treatment, PAI revealed a significant increase (P < .05) in %sO2 and HbT levels in treated tumors compared to untreated controls. Fluorescence imaging at this time point revealed a 46% decrease in mean 2-DG uptake compared to controls. No changes in hemodynamic parameters were observed in mouse salivary gland tissue. A significant decrease in Ki-67 staining (P < .001) and MR-based tumor volume was also observed in Met-treated tumors compared to controls with no change in CD31 + vessel count following Met therapy. CONCLUSION: Our results provide, for the first time, direct in vivo evidence of Met-induced changes in tumor microenvironmental parameters in HNSCC xenografts. Our findings highlight the utility of multimodal functional imaging for non-invasive mapping of the effects of Met in HNSCC. PMID- 29573034 TI - Appropriate utilization of cardiac magnetic resonance for the assessment of heart failure and potential associated cost savings. AB - BACKGROUND: The rapid growth in cardiac imaging utilization has led to the development of appropriate use criteria (AUC) in an effort to control costs. Recently, cardiac MRI has developed into a valuable modality in the evaluation of cardiac disease. However, there are no studies examining the appropriate use of cardiac MRI in clinical practice. PURPOSE: To determine the appropriate utilization of cardiac MRI in a large quaternary care institution and to compare percentages of appropriate utilization pre- and postpublication of the AUC document. We hypothesized that percentages of appropriate cardiac MRI utilization will be similar to those of other comparable cardiac imaging modalities and that there would be a significant change in appropriate use pre- and post-AUC publication. STUDY TYPE: Retrospective cohort study. POPULATION: In all, 2032 consecutive patients undergoing cardiac MRI for the assessment of heart failure between 2012-2016. FIELD STRENGTH: 1.5T. ASSESSMENT: Data were collected and an appropriateness category was assigned for each cardiac MRI. STATISTICAL TESTS: Rates of major cardiac risk factors were compared between those undergoing cardiac MRIs pre- and post-AUC using the chi-square and the Mann-Whitney tests for categorical and continuous variables, respectively. Appropriateness classification was compared pre- and post-AUC publication using the chi-square test. RESULTS: There were no significant differences in the prevalence of major cardiovascular risk factors before and after publication of the AUC. 95.5% of all cardiac MRIs were appropriate based on the AUC. Further, there was a significant difference when comparing the appropriateness classification before and after publication of the AUC (P = 0.0003), potentially associated with annual cost savings of ~$14.8 million. DATA CONCLUSION: We report a very high percentage of appropriate use of cardiac MRI and a significant increase in the proportion of tests classified as appropriate after AUC publication.

AB - Despite the well-recognized importance of immunoglobulin therapy individualization during the treatment of chronic inflammatory demyelinating polyneuropathy (CIDP), the pathway to best achieve optimization is unknown. There are many pharmacokinetic and immunobiologic variables that can potentially influence the appropriateness of any individual therapy. Although identification of specific autoantibodies and their targets has only been accomplished in a minority of patients with CIDP, already the diagnostic and treatment implications of specific autoantibody detection are being realized. Individual variability in IgG pharmacokinetic properties including IgG catabolic rates and distribution, as well as the IgG level necessary for disease control also require consideration during the optimization process. For optimization to be successful there must be a measure of treatment response that has a clinically meaningful interpretation. There are currently available well-defined and validated clinical assessment tools and outcome measures that are well suited for this purpose. While there remains much to learn on how best to manipulate immunopathology and immunoglobulin pharmacokinetics in the most favorable way, there currently exists an understanding of these principles to a degree sufficient to begin to develop rational and evidence-based treatment optimization strategies. PMID- 29573035 TI - Synthesis and physicochemical studies of amyloidogenic hexapeptides derived from human cystatin C. AB - Human cystatin C (hCC) is a low molecular mass protein that belongs to the cystatin superfamily. It is an inhibitor of extracellular cysteine proteinases, present in all human body fluids. At physiological conditions, hCC is a monomer, but it has a tendency to dimerization. Naturally occurring hCC mutant, with leucine in position 68 substituted by glutamine (L68Q), is directly involved in the formation of amyloid deposits, independently of other proteins. This process is the primary cause of hereditary cerebral amyloid angiopathy, observed mainly in the Icelandic population. Oligomerization and fibrillization processes of hCC are not explained equally well, but it is proposed that domain swapping is involved in both of them. Research carried out on the fibrillization process led to new hypothesis about the existence of a steric zipper motif in amyloidogenic proteins. In the hCC sequence, there are 2 fragments which may play the role of a steric zipper: the loop L1 region and the C-terminal fragment. In this work, we focused on the first of these. Nine hexapeptides covering studied hCC fragment were synthesized, and their fibrillogenic potential was assessed using an array of biophysical methods. The obtained results showed that the studied hCC fragment has strong profibrillogenic propensities because it contains 2 fragments fulfilling the requirements for an effective steric zipper located next to each other, forming 1 super-steric zipper motif. This hCC fragment might therefore be responsible for the enhanced amyloidogenic properties of dimeric or partially unfolded hCC.

PMID- 29573036 TI - Three-dimensional visualization of rat retina by X-ray differential phase contrast tomographic microscopy. AB - The retina is one of the most tiny and sophisticated tissues of the body. Three dimensional (3D) visualization of the whole retina is valuable both in clinical and research arenas. The tissue has been predominantly assessed by time-consuming histopathology and optical coherence tomography (OCT) in research and clinical arenas. However, none of the two methods can provide 3D imaging of the retina. The purpose of this study is to give a volumetric visualization of rat retina at submicron resolution, using an emerging imaging technique-phase-contrast X-ray CT. A Sprague-Dawley (SD) rat eye specimen was scanned with X-ray differential phase contrast tomographic microscopy (DPC-microCT) equipped at the Swiss Light Source synchrotron. After scanning, the specimen was subjected to routine histology procedures and severed as a reference. The morphological characteristics and signal features of the retina in the DPC-microCT images were evaluated. The total retina and its sublayers thicknesses were measured on the DPC-microCT images and compared with those obtained from the histological sections. The retina structures revealed by DPC-microCT were highly consistent with the histological section. In this study, we achieved nondestructive 3D visualization of SD rat retina. In addition to detailed anatomical structures, the objective parameters provided by DPC-microCT make it a useful tool for retinal research and disease diagnosis in the early stage. PMID- 29573038 TI - Conditioned pain modulation using painful cutaneous electrical stimulation or simply habituation? AB - BACKGROUND AND AIMS: Cold pressor test was recently reported to significantly reduce painful cutaneous electrical stimulation (PCES)-induced pain and corresponding evoked potentials (PCES-EPs), but whether this reduction is an effect of conditioned pain modulation (CPM) remains unknown. To what extent these findings are confounded by habituation is also unknown. We thus compared the effect of CPM and habituation on PCES-induced pain and PCES-EPs and analysed whether increased attention by a random change of electric stimulation would intensify this possible habituation effect. METHODS: Three custom-built concentric surface electrodes were used to induce a pain intensity of 60 on a 0 100 numerical rating scale (NRS) among 29 healthy subjects (age 20-35y, 16 females). PCES-EPs (including P0N1 and N1P1 amplitudes, N1 latencies) were assessed over Cz. Group A received 14 min of electrical stimulation with constant intensity followed by 14 min of electrical stimulation with variable intensities, group B vice versa. Afterwards, subjects perceived cold-water pain (10 degrees C) contralaterally as conditioning stimulus to assess CPM. Statistical analysis was conducted with ANOVA and t-test. RESULTS: In both groups, N1 latencies remain unchanged, but the intensity of PCES-induced pain (12 +/- 17%; p < 0.01) and N1P1 amplitudes of PCES-EPs (10 +/- 16%; p < 0.05) decreased significantly during the 14-min PCES with constant current intensity. CPM also significantly reduced pain ratings (36 +/- 19%; p < 0.001) and amplitudes (37.2 +/- 15.8%), p < 0.001). A significant decline of P0N1 amplitudes occurred only during CPM (18 +/- 61%; p < 0.001). CONCLUSION: We found a significant effect of habituation on PCES-induced pain and PCES-EPs, although the effect of CPM was significantly larger and could not be explained by habituation alone. SIGNIFICANCE: Painful cutaneous electrical stimulation leads to moderate habituation of pain and evoked potential amplitudes, but the conditioned pain modulation effect using this method is significantly larger, which might indicate a different mechanism in central processing. PMID- 29573039 TI - Tubular dentin sealer penetration after different final irrigation protocols: A confocal laser scanning microscopy study. AB - The aim of this study was to evaluate tubular dentin sealer penetration, comparing different final irrigation protocols using a conventional needle (CONV), EndoActivator system (EAS), EndoVac system (EVS), and ultrasound (PUI). Initially, fifty-two first maxillary molars with a single canal in the palatal root, without abrupt curvatures, resorptive processes, or previous endodontic treatment were selected for this study. Then, the crowns were sectioned to obtain palatal roots 15 mm in length. The root canals were prepared with the ProTaper Universal System and irrigated with 5% NaOCl. Afterwards, the specimens were divided into four groups (n. 13), according to the final irrigation protocol: CONV, EAS, EVS, and PUI. After filling, slices at 3 mm and 5 mm from the apex were obtained for analysis by confocal laser scanning microscopy. Two-way comparisons between the groups and the levels were performed with Games Howell's test (p < .05). Tubular dentin sealer penetration was higher at 5 mm compared with 3 mm from the apex (p < .05). The EAS group showed a higher percentage of tubular dentin sealer penetration, compared with the CONV group, at both levels. At 3 mm, there was no statistically significant difference among EAS, EVS, and PUI; however, these groups showed better performance, compared with the CONV group. At 5 mm, there was no statistically significant difference between the EAS and EVS groups, but both showed higher sealer penetration than the PUI group (p < .05). The EAS and EVS groups achieved better degrees of tubular dentin sealer penetration, compared with the other groups. PMID- 29573040 TI - F463L increases the potential of dofetilide on human ether-a-go-go-related gene (hERG) channels. AB - Mutations in genes related to long QT syndrome (LQTS) is recognized as an independent risk of drug-induced LQTS. We previously screened a mutation F463L in a Chinese patient with LQT2, syncope, and epilepsy. Here, we planned to illustrate how F463L influences the action of dofetilide on hERG channels. F463L hERG plasmids were transfected into the stable Human Embryonic Kidney 293 (HEK293) cells expressing WT-hERG to generate heterozygous mutant (WT + F463L hERG). Whole-cell patch clamp and laser confocal scanning microscopy were used to evaluate electrophysiological consequences and the membrane distribution of hERG protein. In comparison of WT-hERG channels exposed to dofetilide, heterozygous F463L-hERG channels showed a reduction in the density of tail currents when exposed amidarone. F463L-hERG also altered the action of dofetilide on the gating properties of hERG channels. Images of dofetilide-treated cells expressing heterozygous F463L showed a severe retention and reduction of protein expression on the membrane compared to WT. In conclusion, dofetilide displays a powerful inhibitory effect on the currents from cells expressing heterozygous F463L, thus showing an additive suppression of currents by F463L with dofetilide. PMID- 29573041 TI - APOE influences working memory in non-demented elderly through an interaction with SPON1 rs2618516. AB - Exploring how risk genes cumulatively impair brain function in preclinical phase (i.e., in cognitively normal elderly) could provide critical insights into the pathophysiology of Alzheimer's disease (AD). Working memory impairment has always been a considerable cognitive deficit in AD, which is likely under complex genetic control. Though, the APOE E4 allele could damage the working memory performance in normal elderly, dissociable results have been reported. This allele may exert specific effects in contexts with other genetic variants. The rs2618516 in the spondin 1 gene (SPON1) has been associated with AD risk and brain structure in the elderly. SPON1 may interact with APOE through processing the amyloid precursor protein and suppressing amyloid-beta levels. Using neuropsychological tasks from 710 individuals, we found significant SPON1 * APOE genotype interactions in working memory and executive function performances. Moreover, such interaction was also found in regional brain activations based on functional magnetic resonance imaging data with the n-back working memory task performed in a sub-cohort of 64 subjects. The effects of E4 allele on activation of right inferior frontal gyrus, triangular part (IFGtriang.R) were modulated by rs2618516 in a working memory task. Furthermore, lower IFGtriang.R activation was associated with better cognitive functions. Moreover, the IFGtriang.R activation could mediate the impacts of SPON1 * APOE interactions on working memory performance. These findings suggested the importance of weighing APOE effects on brain activation under the working memory task within the context of the SPON1 genotype.

AB - BACKGROUND: Diffusion kurtosis imaging (DKI) measures have been shown to provide increased sensitivity relative to diffusion tensor imaging (DTI) in detecting pathologies. PURPOSE: To compare the sensitivity of DKI-derived kurtosis and diffusion maps for assessment of low-grade gliomas (LGG). STUDY TYPE: Prospective study. POPULATION: In all, 19 LGG patients and 26 healthy control subjects were recruited. FIELD STRENGTH/SEQUENCE: Echo-planar-imaging diffusion-weighted MR images (b-values = 0, 1000, and 2000 with 30 diffusion gradient directions) were acquired on a 3T scanner. ASSESSMENT: Maps for mean, axial, and radial diffusivity (MD, AD, and RD) and kurtosis (MK, AK, and RK), and fractional anisotropy (FA) were evaluated in the tumor, perilesional white matter, and contralateral normal-appearing white matter regions. STATISTICAL TESTING: General linear models (GLM), Cohen's d for effect size estimates, false discovery rate (FDR) for multiple corrections, Cochran Q-test. RESULTS: Pairwise differences were observed for all diffusion and kurtosis measures between the studied regions (FDR P < 0.001), except an FA map that failed to show significant differences between the lesion and perilesional white matter (FDR P = 0.373). Effect size analysis showed that kurtosis metrics were found to be 18.8% (RK, P = 0.144) to 29.1% (AK, P < 0.05) more sensitive in discriminating perilesional regions from the lesion than corresponding diffusion metrics, whereas AK provided a 25.0% (P < 0.05) increase in sensitivity in discriminating perilesional and contralateral white matter. RK was found to be the most sensitive to contralateral white matter differences between low-grade gliomas and controls, with MK and RK providing a significantly greater sensitivity of 587.2% (P < 0.001) and 320.7% (P < 0.001) than MD and RD, respectively. DATA CONCLUSION: Kurtosis maps showed increased sensitivity, as compared to counterpart diffusion maps, for evaluation of microstructural changes in gliomas with a 3-6-fold increment in assessing changes in contralateral white matter.

PMID- 29573043 TI - Compound heterozygosity for loss-of-function FARSB variants in a patient with classic features of recessive aminoacyl-tRNA synthetase-related disease. AB - Aminoacyl-tRNA synthetases (ARSs) are ubiquitously expressed enzymes that ligate amino acids onto tRNA molecules. Genes encoding ARSs have been implicated in phenotypically diverse dominant and recessive human diseases. The charging of tRNAPHE with phenylalanine is performed by a tetrameric enzyme that contains two alpha (FARSA) and two beta (FARSB) subunits. To date, mutations in the genes encoding these subunits (FARSA and FARSB) have not been implicated in any human disease. Here, we describe a patient with a severe, lethal, multisystem, developmental phenotype who was compound heterozygous for FARSB variants: p.Thr256Met and p.His496Lysfs*14. Expression studies using fibroblasts isolated from the proband revealed a severe depletion of both FARSB and FARSA protein levels. These data indicate that the FARSB variants destabilize total phenylalanyl-tRNA synthetase levels, thus causing a loss-of-function effect. Importantly, our patient shows strong phenotypic overlap with patients that have recessive diseases associated with other ARS loci; these observations strongly support the pathogenicity of the identified FARSB variants and are consistent with the essential function of phenylalanyl-tRNA synthetase in human cells. In sum, our clinical, genetic, and functional analyses revealed the first FARSB variants associated with a human disease phenotype and expand the locus heterogeneity of ARS-related human disease. PMID- 29573045 TI - Bioinspired Design of Fe3+ -Doped Mesoporous Carbon Nanospheres for Enhanced Nanozyme Activity. AB - Nanozymes have received considerable attention as alternatives of natural enzymes. However, the catalytic activity of nanozymes is often lower than that of natural enzymes, which largely limits their applications. Current methods utilized to improve the catalytic efficiency and substrate selectivity of a nanozyme usually have some inherent drawbacks. Herein, a biomimetic strategy was developed to design Fe3+ -doped mesoporous carbon nanospheres (Fe3+ -MCNs) as a horseradish peroxidase (HRP) mimic to realize the structure and function mimicking of natural HRP. In this system, Fe3+ ions could act as catalytic centers and carboxyl-modified mesoporous carbon nanospheres (MCNs-COOH) could be used to bind with substrates. As a result, Fe3+ -MCNs showed higher enzymatic activity than that of Fe3 O4 nanoparticles. Therefore, this strategy can contribute to the development of nanozymes and further understanding of the complicated enzymatic reactions in natural and biological systems. PMID- 29573044 TI - Missing data in trial-based cost-effectiveness analysis: An incomplete journey. AB - Cost-effectiveness analyses (CEA) conducted alongside randomised trials provide key evidence for informing healthcare decision making, but missing data pose substantive challenges. Recently, there have been a number of developments in methods and guidelines addressing missing data in trials. However, it is unclear whether these developments have permeated CEA practice. This paper critically reviews the extent of and methods used to address missing data in recently published trial-based CEA. Issues of the Health Technology Assessment journal from 2013 to 2015 were searched. Fifty-two eligible studies were identified. Missing data were very common; the median proportion of trial participants with complete cost-effectiveness data was 63% (interquartile range: 47%-81%). The most common approach for the primary analysis was to restrict analysis to those with complete data (43%), followed by multiple imputation (30%). Half of the studies conducted some sort of sensitivity analyses, but only 2 (4%) considered possible departures from the missing-at-random assumption. Further improvements are needed to address missing data in cost-effectiveness analyses conducted alongside randomised trials. These should focus on limiting the extent of missing data, choosing an appropriate method for the primary analysis that is valid under contextually plausible assumptions, and conducting sensitivity analyses to departures from the missing-at-random assumption. PMID- 29573047 TI - A randomized controlled trial of a group intervention for siblings of children with cancer: Changes in symptoms of anxiety in siblings and caregivers. AB - OBJECTIVE: This study assessed the effects of a group intervention-Siblings Coping Together (SibCT)-on siblings' and caregivers' anxiety symptoms compared to controls, and potential moderators. METHODS: Seventy healthy siblings of children on or off treatment (7-16 y old, 41 males) participated in a randomized controlled trial (RCT) with 2 arms/groups: SibCT (n = 41) and an attention control (CG) (n = 34). Both groups had eight 2-hour weekly sessions. EG followed SibCT's educational, social, and problem-solving activities. CG had planned games and crafts. Siblings and caregivers self-reported on anxiety symptoms at baseline, intervention end, and 3 months later. Multivariable mixed model analyses examined the intervention effect over time, and potential moderators (gender, on/off ill child's treatment). RESULTS: No main effects of group or time were found in sibling scores. A group * gender interaction (P < .05) indicated that in the intervention group female siblings reported less total anxiety symptoms than male siblings, with no significant gender differences in the control group. Caregivers' total anxiety symptoms declined over time (P < .02). A group * on/off treatment interaction in physiological/panic subscale (P < .03) indicated that when ill child was on treatment, caregivers of siblings in SibCT reported less anxiety compared with caregivers of CG. CONCLUSIONS: There was no clear SibCT intervention effect. SibCT may benefit female siblings, and caregivers whose ill child is on active treatment. Contextual factors (gender) seem to influence psychosocial intervention in this population. PMID- 29573046 TI - Meta-analytic evidence for altered mesolimbic responses to reward in schizophrenia. AB - Dysfunction of reward-related neural circuitry in schizophrenia (SCZ) has been widely reported, and may provide insight into the motivational and cognitive disturbances that characterize the disorder. Although previous meta-analyses of reward learning paradigms in SCZ have been performed, a meta-analysis of whole brain coordinate maps in SCZ alone has not been conducted. In this study, we performed an activation likelihood estimate (ALE) meta-analysis, and performed a follow-up analysis of functional connectivity and functional decoding of identified regions. We report several salient findings that extend prior work in this area. First, an alteration in reward-related activation was observed in the right ventral striatum, but this was not solely driven by hypoactivation in the SCZ group compared to healthy controls. Second, the region was characterized by functional connectivity primarily with the lateral prefrontal cortex and pre supplementary motor area (preSMA), as well as subcortical regions such as the thalamus which show structural deficits in SCZ. Finally, although the meta analysis showed no regions outside the ventral striatum to be significantly altered, regions with higher functional connectivity with the ventral striatum showed a greater number of subthreshold foci. Together, these findings confirm the alteration of ventral striatal function in SCZ, but suggest that a network based approach may assist future analysis of the functional underpinnings of the disorder. PMID- 29573048 TI - Rehabilitation of Edentulism and Mortality: A Systematic Review. AB - PURPOSE: It has been shown that tooth loss is associated with an increased risk of early mortality, and that prosthetic rehabilitation of edentulism improves quality of life and reduces morbidity. This review examines association between prosthetic rehabilitation of the edentulous state with a complete denture and mortality. METHODS: A systematic search using combinations of related keywords for "complete denture" and "mortality" was performed on PubMed, Web of Science, and Google Scholar. A reference search of included articles and author contacts was also performed. RESULTS: None of the studies reported results for association between mortality and wearing complete dentures among edentulous individuals; however, based on the published methods and results, a total of 15 studies were found to be eligible for author contacts to obtain relevant data. Overall, 5 eligible studies were included and critically evaluated to summarize their findings. The follow-up period in these studies ranged from 3 to 24 years, and the age group of included samples ranging from 52 to 105 years. The proportion of individuals not wearing dentures ranged from 3.0% to 13.3%. Four of the included studies showed fewer individuals without complete dentures surviving over the follow-up years as compared to the group wearing complete dentures. One of two studies that could adjust for certain confounders found no significant difference in mortality after adjusting, but another study found a 42% reduced risk of dying among those wearing complete dentures, as compared to those not wearing complete dentures after adjusting for age, sex, educational level, smoking, alcohol drinking, body mass index, time spent walking daily, medical history, psychological distress score, energy intake, and protein intake. Due to the small sample size of nondenture wearers, it was not possible to analyze with statistical rigor the comparative risk of dying associated with wearing or not wearing complete dentures. CONCLUSION: Most of the included studies indicated a higher proportion of deceased edentulous patients not using dentures as compared to denture wearers. Nevertheless, small sample size prevents a definite conclusion being drawn regarding a relationship between prosthetic rehabilitation and mortality among edentulous individuals. PMID- 29573049 TI - Hemoglobin Seattle detection based on low capillary oxygen saturation: First reported case in Japan. PMID- 29573050 TI - MRI for solitary pulmonary nodule and mass assessment: Current state of the art. AB - : Since the clinical introduction of magnetic resonance imaging (MRI), the chest has been one of its most challenging applications, and many physicists and radiologists have tried since the 1980s to use MR for assessment of different lung diseases as well as mediastinal and pleural diseases. Since then, however, technical advances in sequencing, scanners, and coils, adaptation of parallel imaging techniques, utilization of contrast media, and development of postprocessing tools have been reported by many basic and clinical researchers. As a result, state-of-the-art thoracic MRI is now substituted for traditional imaging techniques and/or plays a complementary role in the management of patients with various chest diseases, and especially in the detection of pulmonary nodules and in thoracic oncology. In addition, MRI has continued to be developed to help overcome the limitations of computed tomography (CT) and nuclear medicine examinations. It can currently provide not only morphological, but also functional, physiological, pathophysiological, and molecular information at 1.5T with a gradual shift from 1.5T to 3T MR systems. In this review, we focus on these recent advances in MRI for pulmonary nodule detection and pulmonary nodule and mass evaluation by using noncontrast-enhanced and contrast-enhanced techniques as well as new molecular imaging methods such as chemical exchange saturation transfer imaging for a comparison with other modalities such as single or multidetector row CT, 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET), and/or PET/CT.

PMID- 29573051 TI - Altered attentional control linked to catastrophizing in patients with irritable bowel syndrome. AB - OBJECTIVES: Our study aimed to investigate differences in attentional control between patients with irritable bowel syndrome (IBS) and healthy participants and to examine the link between attentional control and IBS catastrophizing. Previous research has shown that patients with chronic functional illnesses have lower levels of attentional control. However, no previous study has found altered attentional control in patients with IBS or directly investigated the link between attentional control and catastrophizing. We also aimed to establish whether anxiety is associated with attentional functions in patients with IBS. DESIGN AND METHODS: In this cross-sectional study, we compared 41 IBS patients with 39 healthy-matched control participants on attentional functions using an attention network task. IBS catastrophizing (Gastrointestinal Cognitions), IBS symptom severity (GSRS-IBS), Depression, Anxiety, and Stress (DASS-21), and Visceral Anxiety Sensitivity were assessed using self-report measures. RESULTS: Patients with IBS had lower attentional control compared to healthy participants, t (78) = -2.75, p = .007, d = .62. Groups did not differ in alerting or orienting attention. IBS patients with lower attentional control scored higher on IBS catastrophizing than those with higher attention control, t (38.59) = 2.19, p = .032, d = .66. Anxiety was related to orienting attention in the IBS group (rho = .38, p = .015). CONCLUSIONS: Patients with IBS displayed reduced attentional control. Crucially, those patients with lower attentional control also had more catastrophizing thoughts than patients with better attentional control. These findings suggest that improving attentional control could be a valid target for psychological interventions for IBS. Statement of contribution What is already known on this subject? It has been hypothesised that psychological processes play a role in the maintenance of irritable bowel syndrome (IBS), and altered levels of attentional control have been found in patients with other functional illnesses but not yet in patients with IBS. Pain catastrophizing, a maladaptive thinking pattern, has been linked with IBS symptom severity, and previous research has shown an association between attentional control and intrusive thoughts. Whether there is an association between catastrophizing thoughts and attentional control in patients with IBS is unknown. What does this study add? Patients with irritable bowel syndrome show reduced levels of attentional control. IBS patients with lower levels of attentional control have more catastrophizing thoughts. Therapies emphasizing attentional control training may help reduce catastrophizing. PMID- 29573052 TI - A homozygous variant disrupting the PIGH start-codon is associated with developmental delay, epilepsy, and microcephaly. AB - Defective glycosylphosphatidylinositol (GPI)-anchor biogenesis can cause a spectrum of predominantly neurological problems. For eight genes critical to this biological process, disease associations are not yet reported. Scanning exomes from 7,833 parent-child trios and 1,792 singletons from the DDD study for biallelic variants in this gene-set uncovered a rare PIGH variant in a boy with epilepsy, microcephaly, and behavioral difficulties. Although only 2/2 reads harbored this c.1A > T transversion, the presence of ~25 Mb autozygosity at this locus implied homozygosity, which was confirmed using Sanger sequencing. A similarly-affected sister was also homozygous. FACS analysis of PIGH-deficient CHO cells indicated that cDNAs with c.1A > T could not efficiently restore expression of GPI-APs. Truncation of PIGH protein was consistent with the utilization of an in-frame start-site at codon 63. In summary, we describe siblings harboring a homozygous c.1A > T variant resulting in defective GPI anchor biogenesis and highlight the importance of exploring low-coverage variants within autozygous regions. PMID- 29573053 TI - Barriers to and enablers of implementing antimicrobial stewardship programs in veterinary practices. AB - BACKGROUND: Antimicrobial stewardship (AMS) programs are yet to be widely implemented in veterinary practice and medical programs are unlikely to be directly applicable to veterinary settings. OBJECTIVE: To gain an in-depth understanding of the factors that influence effective AMS in veterinary practices in Australia. METHODS: A concurrent explanatory mixed methods design was used. The quantitative phase of the study consisted of an online questionnaire to assess veterinarians' attitudes to antimicrobial resistance (AMR) and antimicrobial use in animals, and the extent to which AMS currently is implemented (knowingly or unknowingly). The qualitative phase used semi structured interviews to gain an understanding of the barriers to and enablers of AMS in veterinary practices. Data were collected and entered into NVivo v.11, openly coded and analyzed according to mixed methods data analysis principles. RESULTS: Companion animal, equine, and bovine veterinarians participated in the study. Veterinary practices rarely had antimicrobial prescribing policies. The key barriers were a lack of AMS governance structures, client expectations and competition between practices, cost of microbiological testing, and lack of access to education, training and AMS resources. The enablers were concern for the role of veterinary antimicrobial use in development of AMR in humans, a sense of pride in the service provided, and preparedness to change prescribing practices. CONCLUSION AND CLINICAL IMPORTANCE: Our study can guide development and establishment of AMS programs in veterinary practices by defining the major issues that influence the prescribing behavior of veterinarians. PMID- 29573054 TI - Relational ethics of delirium care: Findings from a hospice ethnography. AB - Delirium, a common syndrome in terminally ill people, presents specific challenges to a good death in end-of-life care. This paper examines the relational engagement between hospice nurses and their patients in a context of end-of-life delirium. Ethnographic fieldwork spanning 15 months was conducted at a freestanding residential hospice in eastern Canada. A shared value system was apparent within the nursing community of hospice; patients' comfort and dignity were deemed most at stake and therefore commanded nurses' primary attention. This overarching commitment to comfort and dignity shaped all of nursing practice in this hospice, including practices related to end-of-life delirium. The findings of this study elaborate the ways in which hospice nurses interpreted and responded to the discomfort of their patients in delirium, as well as the efforts they made to understand their patients' subjective experiences and to connect with them in supportive ways. In addition to what is already known about clinical assessment and treatment of delirium in palliative care settings, the findings of this study offer points of reflection for nurses anywhere who are contending with the relational challenges that delirium presents in end-of-life care. PMID- 29573056 TI - Physicians, sick leave certificates, and patients' subsequent employment outcomes. AB - I analyze how general practitioners (GPs) indirectly affect their patients' employment outcomes by deciding the length of sick leaves. I use an instrumental variables framework where spell durations are identified through supply-side certification measures. I find that a day of sick leave certified only because the worker's GP has a high propensity to certify sick leaves decreases the employment probability persistently by 0.45-0.69 percentage points, but increases the risk of becoming unemployed by 0.28-0.44 percentage points. These effects are mostly driven by workers with low job tenure. Several robustness checks show that endogenous matching between patients and GPs does not impair identification. My results bear important implications for doctors: Whenever medically justifiable, certifying shorter sick leaves to protect the employment status of the patient may be beneficial.

AB - BACKGROUND: Novel feline RBC antigens might contribute to decreased efficacy of RBC transfusion and increased incidence of acute transfusion reactions (ATR). OBJECTIVES: To examine the effect of major cross-match in transfusion-naive anemic cats on the incidence of acute immunologic transfusion reaction and transfusion efficacy for up to 24 hours after transfusion. ANIMALS: Forty-eight client owned transfusion-naive anemic cats. METHODS: Prospective, randomized, controlled study. All transfusion-naive cats receiving packed red blood cells (pRBC) transfusions from January 2016 to August 2017 were eligible for inclusion. Cats in the study group received cross-match and blood type compatible pRBCs and cats in the control group received noncross-matched blood type compatible pRBCs. Incidence of ATR and change in PCV after transfusion was recorded. RESULTS: No significant difference in incidence of transfusion reactions between cross matched and noncross-matched groups (CM+ 4/24; 17%, CM- 7/24; 29%, P = .16). No significant difference between groups in mean change in PCV after transfusion scaled to dose of pRBCs administered at any time point after transfusion (immediate: CM+ 0.62 +/- 0.59, CM- 0.75 +/- 0.48, P = .41; 1 hour: CM+ 0.60 +/- 0.66, CM- 0.74 +/- 0.53, P = .43; 12 hours: CM+ 0.70 +/- 0.55, CM- 0.66 +/- 0.60, P = .81; 24 hours: CM+ 0.64 +/- 0.71, CM- 0.55 +/- 0.48, P = .70). CONCLUSIONS AND CLINICAL IMPORTANCE: Our results do not support use of the major cross-match test to increase efficacy of, and to decrease adverse events associated with, RBC transfusion in AB blood typed transfusion-naive cats.

PMID- 29573058 TI - Molecular genomic landscapes of hepatobiliary cancer. AB - Hepatocellular carcinoma (HCC) and biliary tract cancer are more frequent in East Asia including Japan than in Europe or North America. A compilation of 1340 multi ethnic HCC genomes, the largest cohort ever reported, identified a comprehensive landscape of HCC driver genes, comprised of three core drivers (TP53, TERT, and WNT signaling) and combinations of infrequent alterations in various cancer pathways. In contrast, five core driver genes (TP53, ARID1A, KRAS, SMAD4, and BAP1) with characteristic molecular alterations including fusion transcripts involving fibroblast growth factor receptor 2 and the protein kinase A pathway, and IDH1/2 mutation constituted the biliary tract cancer genomes. Consistent with their heterogeneous epidemiological backgrounds, mutational signatures and combinations of non-core driver genes within these cancer genomes were found to be complex. Integrative analyses of multi-omics data identified molecular classifications of these tumors that are associated with clinical outcome and enrichments of potential therapeutic targets, including immune checkpoint molecules. Translating comprehensive molecular-genomic analysis together with further basic research and international collaborations are highly anticipated for developing precise and better treatments, diagnosis, and prevention of these tumor types. PMID- 29573059 TI - Community managed alcohol programs in Canada: Overview of key dimensions and implementation. AB - INTRODUCTION AND AIMS: People with severe alcohol dependence and unstable housing are vulnerable to multiple harms related to drinking and homelessness. Managed Alcohol Programs (MAP) aim to reduce harms of severe alcohol use without expecting cessation of use. There is promising evidence that MAPs reduce acute and social harms associated with alcohol dependence. The aim of this paper is to describe MAPs in Canada including key dimensions and implementation issues. DESIGN AND METHODS: Thirteen Canadian MAPs were identified through the Canadian Managed Alcohol Program Study. Nine key informant interviews were conducted and analysed alongside program documents and reports to create individual case reports. Inductive content analysis and cross case comparisons were employed to identify six key dimensions of MAPs. RESULTS: Community based MAPs have a common goal of preserving dignity and reducing harms of drinking while increasing access to housing, health and social services. MAPs are offered as both residential and day programs with differences in six key dimensions including program goals and eligibility, food and accomodation, alcohol dispensing and administration, funding and money management, primary care services and clinical monitoring, and social and cultural connections. DISCUSSION AND CONCLUSIONS: MAPs consist of four pillars with the alcohol intervention provided alongside housing interventions, primary care services, social and cultural interventions. Availability of permanent housing and re-establishing social and cultural connections are central to recovery and healing goals of MAPs. Additional research regarding Indigenous and gendered approaches to program development as well as outcomes related to chronic harms and differences in alcohol management are needed.

PMID- 29573062 TI - Developing Student Evidence-Based Practice Questionnaire (S-EBPQ) for undergraduate nursing students: Reliability and validity of a Chinese adaptation. AB - RATIONALE, AIMS, AND OBJECTIVES: The assessment of evaluating undergraduate nursing students' evidence-based practice engagement is an important issue, yet few tools have been developed specifically in Mainland China. The purpose of this study was to adapt the Student Evidence-based Practice Questionnaire (S-EBPQ) to Mainland China's cultural context and to evaluate the psychometric properties of the newly adapted Chinese S-EBPQ. METHODS: Cross-cultural adaptation, including translation of the original S-EBPQ into Mandarin Chinese language, was performed according to published guidelines. A pilot study was conducted in Mainland China with 25 Chinese undergraduate nursing students. A subsequent validation study was conducted with 400 undergraduate nursing students from Mainland China. Construct validity was assessed by exploratory factor analysis (n = 190) and confirmatory factor analysis (n = 210). Reliability was determined using internal consistency and test-retest reliability. RESULTS: The split-half coefficient for the overall Chinese S-EBPQ was 0.858. A content validity index of 0.986 was achieved. Principal component analysis resulted in a 4-factor structure explaining 68.285% of the total variance. The comparative fit index was 0.927, and the root mean squared error of approximation was 0.072 from the confirmatory factor analysis. Known-group validity was supported by the significant differences according to various characteristics of participants. Internal consistency was high for the Chinese S-EBPQ reaching a Cronbach alpha value of 0.934. Test-retest reliability was 0.821. CONCLUSION: The newly cross-culturally adapted S-EBPQ possesses adequate validity, test-retest reliability, and internal consistency and therefore may be utilized in nursing education to assess EBP of undergraduate nursing students in Mainland China. PMID- 29573061 TI - Circulating exosomes contain protein biomarkers of metastatic non-small-cell lung cancer. AB - The present study aimed to investigate the overall changes in exosomal proteomes in metastatic and non-metastatic non-small-cell lung cancers (NSCLC) and healthy human serum samples, and evaluate the potential of serum exosomal biomarkers to predict NSCLC metastasis. Tandem mass tags combined with multidimensional liquid chromatography and mass spectrometry analysis were used for screening the proteomic profiles of serum samples. Quantitative proteome, significant pathway, and functional categories of patients with metastatic and non-metastatic NSCLC and healthy donors were investigated. In total, 552 proteins of the 628 protein groups identified were quantified. Bioinformatics analysis indicated that quantifiable proteins were mainly involved in multiple biological functions, metastasis-related pathways. Moreover, lipopolysaccharide-binding proteins (LBP) in the exosomes were found to be well distinguished between patients with metastatic and patients with non-metastatic NSCLC. Area under the curve (AUC) was 0.803 with a sensitivity of 83.1% and a specificity of 67% (P < .0001). Circulating LBP were also well distinguishable between metastatic and non metastatic NSCLC, the AUC was 0.683 with a sensitivity of 79.5% and a specificity of 47.2% (P = .005). This novel study provided a reference proteome map for metastatic NSCLC. Patients with metastatic and non-metastatic NSCLC differed in exosome-related proteins in the serum. LBP might be promising and effective candidates of metastatic NSCLC. PMID- 29573063 TI - Pattern of video game use in children with attention-deficit-hyperactivity disorder and typical development. AB - BACKGROUND: Video game playing is a favorite leisure activity among children worldwide. Individuals with attention-deficit-hyperactivity disorder (ADHD) often lack self-control, making them at risk for substance abuse and game addiction. There are conflicting results, however, between studies on the pattern of video gaming and game addiction between those with ADHD and healthy controls. We therefore compared the pattern of video game use and game addiction between Thai children with ADHD and healthy controls. METHODS: A total of 80 participants with ADHD (median age, 9.5 years) and 102 controls (median age, 10 years) were recruited in this study. ADHD was diagnosed by a developmental pediatrician. Each control subject's teacher completed the ADHD questionnaire to ensure that they did not have the diagnosis of ADHD. Pattern of video game use and Game Addiction Screening Test (GAST) were completed by participants' parents. RESULTS: More than half of the children with and without ADHD spent >2 h/day playing video games rather than engaging in other age-appropriate leisure activities, particularly on weekends. Participants with ADHD, however, had a higher rate of compulsive video game use than controls (37.5% vs 11.8%, P < 0.001). CONCLUSIONS: Although video game playing was relatively prevalent in children regardless of ADHD status, those with ADHD had a higher rate of problematic video game use than controls. The pattern of leisure activities including video game use should be assessed during health supervision visits. As such, those at risk for game addiction could be identified early, resulting in appropriate intervention. PMID- 29573064 TI - Prevalence, risk factors and complications of oropharyngeal dysphagia in stroke patients: A cohort study. AB - BACKGROUND: Oropharyngeal dysphagia (OD) is a prevalent poststroke condition with severe complications and increased mortality. Poststroke OD prevalence varies among studies and there is little evidence of its related risk factors and associated complications. OBJECTIVE: to evaluate the prevalence of OD after stroke and the risk factors and associated complications. METHODS: We performed a prospective longitudinal study of stroke patients consecutively admitted to a general hospital. OD was diagnosed with the volume-viscosity swallow test (V VST). Demographic, functional status and topographical and clinical variables of stroke were collected to assess risk factors for OD. We evaluated functional status, mortality, respiratory infections, and readmissions 3 and 12 months after stroke. A multivariate regression analysis determined associated risk factors for OD and for each outcome variable. KEY RESULTS: We included 395 stroke patients with a 45.06% prevalence of OD on admission. OD was independently associated with age (OR = 1.05; CI = 1.02-1.08), previous stroke (OR = 2.40; CI = 1.00-5.79), severity using the National Institute of Health Stroke Scale (OR = 3.52; CI = 1.57-7.87) and volume of the lesion (OR = 1.02; CI = 1.01-1.03). OD after stroke was an independent risk factor for prolonged hospital stay (P = .049; beta = 0.938) and institutionalization after discharge (OR = 0.47; CI = 0.24-0.92); OD was an independent risk factor for poorer functional capacity (OR = 3.00; CI = 1.58-5.68) and increased mortality (HR = 6.90; CI = 1.57-30.34) 3 months after stroke. CONCLUSIONS & INFERENCES: Poststroke OD is prevalent and associated with poor short and long term prognosis. Stroke severity and patient status before stroke were more relevant to OD than lesion location. Systematic screening programs and early OD management could significantly improve poststroke patient outcome.

A total of 200 patient scans, (100 female and 100 male patients), were enrolled in the study. In total, 800 teeth were analysed, and teeth with additional canals in their MB roots (MB2) were identified. First maxillary molar teeth exhibited the highest prevalence of MB2 canals, 92% and 87%, for teeth 16 and 26, respectively. Second maxillary molar teeth showed a lower prevalence of MB2 canals, 69% and 65%, for the 17 and 27, respectively. There were no associations of significance between the prevalence of MB2 canals and patient age or gender. Root morphology and anatomy of permanent maxillary first and second molar teeth was found to be highly variable. The prevalence of additional canals in the MB roots is a frequent finding which has previously been underreported. PMID- 29573066 TI - Infant colic or early symptom of autism spectrum disorder? AB - BACKGROUND: Gastrointestinal (GI) disorders are common in autism spectrum disorder (ASD). Infant colic (IC), the functional GI disorder of infancy, has not been evaluated in this patient group. The aim of this study was therefore to determine the rate of IC in ASD and investigate a possible association between ASD and IC. METHODS: The subjects consisted of 100 ASD patients (mean age, 6.6 +/ 3.5 years) and 100 healthy controls (mean age, 5.3 +/- 2.8 years). The parents were questioned using the diagnostic criteria for infant colic for clinical research purposes defined in Rome IV to diagnose IC, retrospectively. The sample size was estimated using a maximum type I error probability of 5% (alpha) and a type II error of 20%. RESULTS: The rate of IC was 16% and 17% in the ASD group and control group, respectively (P ? 0.05). Excessive crying with late onset and long duration in infants was defined as persistent crying. The rate of persistent crying was significantly higher in the ASD group than in the control group (32% vs 9%, P < 0.001). The relative risk of persistent crying was 4.40 in ASD. The likelihood of being misdiagnosed with IC in this group was 78%. CONCLUSION: The rate of IC is not increased in patients with ASD, but infants with excessive crying should be very thoroughly evaluated before being diagnosed with IC. In particular, persistent crying in infants (i.e. excessive crying with late onset and long duration) may be an early symptom of ASD. PMID- 29573067 TI - Single-use flexible bronchoscopes compared with reusable bronchoscopes: Positive organizational impact but a costly solution. AB - RATIONALE, AIMS, AND OBJECTIVES: There is at present no standard methodology to analyse the organizational impacts (OIs) of medical devices (MDs), and the field is still in its infancy. The aim of the present study was to assess, at a hospital level, the organizational and economic impacts of the introduction of a new MD, specifically the single-use flexible bronchoscope (FB). METHODS: Both the organizational and economic impacts of the single-use FB were evaluated in comparison with the reusable FB currently used as standard practice in our institution. First, process maps were created for both devices (reusable and single use). Based on the 12 types of OI defined by Roussel et al, interviews were conducted with all stakeholders, and the positive and negative aspects of the reusable and single-use processes were analysed. In a second step, microcosting analysis was conducted to determine the most economical balance in use of the 2 technologies. RESULTS: Process maps highlighted the complexity of the reusable device process when compared with the single-use device process. Among the 12 types of OI, the single-use FB process scored better than the reusable FB process in 75% of cases. With the "fleet" of 15 reusable FBs available in our institution, using single-use FBs would represent an extra cost of ?154 per procedure. Single-use and reusable devices would have the same cost (?232 per procedure) with a theoretical annual activity of 328 bronchoscopies, which is much lower than our current activity (1644 procedures per year). CONCLUSIONS: Organizational impact should be considered when assessing MDs. We show in this study that from an organizational viewpoint, there are many advantages to using single-use bronchoscopes. However, in economic impact, it is more cost-effective for our institution, with more than 1500 bronchoscopies performed annually, to use reusable devices. PMID- 29573068 TI - Revealing the Formation Mechanism of CsPbBr3 Perovskite Nanocrystals Produced via a Slowed-Down Microwave-Assisted Synthesis. AB - We developed a microwave-assisted slowed-down synthesis of CsPbBr3 perovskite nanocrystals, which retards the reaction and allows us to gather useful insights into the formation mechanism of these nanoparticles, by examining the intermediate stages of their growth. The trends in the decay of the emission intensity of CsPbBr3 nanocrystals under light exposure are well correlated with their stability against decomposition in TEM under electron beam. The results show the change of the crystal structure of CsPbBr3 nanocrystals from a deficient and easier to be destroyed lattice to a well crystallized one. Conversely the shift in the ease of degradation sheds light on the formation mechanism, indicating first the formation of a bromoplumbate ionic scaffold, with Cs-ion infilling lagging a little behind. Increasing the cation to halide ratio towards the stoichiometric level may account for the improved radiative recombination rates observed in the longer reaction time materials. PMID- 29573069 TI - Role of TRPV1 receptor in inflammation and impairment of esophageal mucosal integrity in a murine model of nonerosive reflux disease. AB - BACKGROUND: Microscopic inflammation and impairment of the esophageal epithelial barrier are considered relevant for perception of symptoms in patients with nonerosive reflux disease (NERD). In these patients, the receptor transient receptor potential vanilloid 1 (TRPV1) is overexpressed in the esophageal mucosa, but its role is not yet fully understood. We evaluated the role of TRPV1 in esophageal inflammation and mucosal barrier impairment in a murine model of NERD. METHODS: Nonerosive reflux disease was surgically induced in Swiss mice by pyloric substenosis and ligature of the gastric fundus, and the mice were killed 7 days post surgery. The experimental groups were: I, sham surgery (negative control); II, NERD untreated; III and IV, NERD + SB366791 or capsazepine (TRPV1 antagonists); and V, NERD + resiniferatoxin (for long-term desensitization of TRPV1). The esophagus was collected for western blotting and histopathology and for evaluation of wet weight, myeloperoxidase (MPO), keratinocyte-derived chemokine (KC), transepithelial electrical resistance (TEER), and basal permeability to fluorescein. KEY RESULTS: Compared to sham, NERD mice had increased esophageal wet weight and MPO and KC levels. The mucosa had no ulcers but exhibited inflammation. NERD mice showed mucosal TRPV1 overexpression, a more pronounced decrease in TEER at pH 0.5 (containing pepsin and taurodeoxycholic acid), and increased basal permeability. Pharmacological modulation of TRPV1 prevented esophageal inflammation development, TEER changes by acidic exposure, and increase in esophageal permeability. CONCLUSIONS & INFERENCES: The TRPV1 receptor has a critical role in esophageal inflammation and mucosal barrier impairment in NERD mice, suggesting that TRPV1 might be a pharmacological target in patients with NERD. PMID- 29573070 TI - Geriatric Psychotropic Stewardship Team to de-escalate inappropriate psychotropic medications in general medicine inpatients: An evaluation. AB - OBJECTIVES: To assess the feasibility and effectiveness of a Geriatric Psychotropic Stewardship Team (GPST) and to achieve inpatient de-escalation of inappropriate psychotropic medications in patients aged over 65 years on a general medicine ward. METHODS: A multidisciplinary GPST conducted twice-weekly rounds on general medicine inpatients known to be taking psychotropic medications. A consensus recommendation was generated, with subsequent treating team action recorded. RESULTS: A total of 125 patients taking 180 psychotropic medications were identified for GPST review. Of these, 32 medications (18%) had been ceased by the treating team prior to GPST review. Adoption of GPST recommendations at 24 hours and at discharge occurred for 85 medications (57%) and 79 medications (53%), respectively. CONCLUSIONS: This study demonstrates the feasibility of a structured multidisciplinary approach in the de-escalation of inappropriate psychotropic medications in older hospital patients on a general medicine ward. Further studies are required to assess scalability and long-term clinical outcomes. PMID- 29573071 TI - Endodontic decision making for asymptomatic root-filled teeth with apical periodontitis - A radiographic survey. AB - The aim of the study was to compare decision making for asymptomatic root-filled teeth among dentists with differing educational backgrounds. Case scenarios based on 14 radiographs were created and 150 participants were asked to choose from five alternative treatment decisions and to state the rationale. Demographic data of the participants were recorded. Frequency distribution and cross-tabulation were performed; chi square testing was used for comparisons and logistic regression was performed to detect significant differences. The overall response rate was 87.3%. The practitioners chose intervention predominantly with non surgical retreatment a common choice. Poor technical quality was a driving factor, while the existing poor coronal restoration and the need for a crown were generally not taken into account by general dentists. Speciality and experience were significant factors. Practitioners were more inclined to retain rather than extract teeth. It is concluded that clear guidelines listing factors to consider for intervention are required. PMID- 29573072 TI - Prevalence and risk factors of halitosis in Japanese school children. AB - BACKGROUND: Little data are available regarding halitosis in Japanese children. The aim of the current study was to investigate the prevalence and risk factors associated with halitosis in Japanese elementary and junior high school children. METHODS: The subjects consisted of 520 elementary (1st-6th grade: boys, n = 284; girls, n = 236) and 248 junior high (7th-9th grade: boys, n = 136; girls, n = 112) school children aged 6-15 years in Saitama Prefecture, Japan. A self administered questionnaire survey; halitosis measurement using an organoleptic assessment method; and clinical oral examination were conducted. RESULTS: Overall, 44.9% of subjects had halitosis. The proportion of boys with halitosis was 43.6% and that of girls was 46.6%. On logistic regression analysis, grade and tongue coating were significant predictors of halitosis. The 7th-9th graders were significantly more likely to have halitosis than 1st-3rd graders (OR, 1.83; P = 0.007). Subjects with area of tongue coating score 2 or 3 were 5.51-fold more likely to present with halitosis (P < 0.001) than those with area of tongue coating score 0 or 1. Similarly, subjects with thickness of tongue coating score 2 or 3 were 3.28-fold more likely to have halitosis than those with thickness of tongue coating score 0 or 1 (P < 0.001). CONCLUSIONS: Halitosis in the school children is not a rare condition; instead, its occurrence is relatively high. Therefore, inclusion of a halitosis prevention and management component in school oral health programs would lead to the promotion of overall oral health.

AB - This study reports a DNA nanoswitch that can be used for visual display of outputs resulting from hybridization events of specific molecular inputs. Conformational changes of the DNA nanoswitch triggered by input DNA strands yield different "pixels" that collectively produce a graphical output on an agarose gel. This system has potential in molecular computation and biosensing approaches in which individual binding results can be translated into macromolecular visual readouts. PMID- 29573074 TI - Under-utilisation of beta-blockers in patients with acute coronary syndrome and comorbid chronic obstructive pulmonary disease. AB - BACKGROUND: beta-blockers are an established mainstay of therapy in acute coronary syndrome (ACS). Despite substantial evidence of their safety and efficacy in chronic obstructive pulmonary disease (COPD) patients, their use in this population remains limited internationally, likely due to fears of inducing bronchospasm. In Australia, little is known about the use of beta-blockers in COPD patients hospitalised for ACS. AIM: To determine if beta-blockers are under prescribed at discharge for patients with COPD hospitalised for ACS compared to patients without a diagnosis of COPD. METHODS: Retrospective analysis of a tertiary metropolitan hospital computer database was undertaken to identify the first 250 patients hospitalised with ACS from 1 March 2015. RESULTS: Of the 250 patients analysed, there were five in-hospital fatalities, leaving 245 patients for final analysis. Patients with ACS and COPD received fewer beta-blockers at discharge than those with ACS alone (66.7% vs 86.2%, P < 0.05). After controlling for clinically meaningful confounding factors, a logistic regression analysis model determined that, for patients with ACS, the presence of COPD was the only significant predictor of receiving a beta-blocker at discharge. CONCLUSION: Despite strong evidence supporting the use of beta-blockers in COPD patients with ACS, Australian patients with COPD remain under-treated for ACS. More work is needed to alter prescribing attitudes. PMID- 29573075 TI - Plasmodium falciparum infection transmitted by transfusion: A cause of hemophagocytic syndrome after bone marrow tranplantation in a non-endemic country. AB - A 27-year-old man with severe aplastic anemia underwent bone marrow transplantation from his HLA identical brother in July 2016. Conditioning included ATGAM 30 mg/kg for 3 days and Cyclophosphamide 50 mg/kg for 4 days. The patient received several platelet and red blood cell transfusions before and after the conditioning. The patient received broad spectrum antibiotics and caspofungin because persistant febrile neutropenia without bacteriological or mycological documentation. Hemophagocytic syndrome was diagnosed on day +12. Steroids at 1 mg/kg were started on day +12. Fever resolved the same day but resumed 3 days later associated to intravascular hemolysis with no schizocytes on blood smears and negative DAT. Thick blood film smears performed on day +26 revealed Plasmodium falciparum parasites (parasitemia = 20%). Except the level of parasitemia, there were no signs of gravity. Quinine was started on day 26 at a loading dose of 15 mg/kg followed by 8 mg/kg three times a day for 20 doses. Fever vanished after 2 days. Parasitemia cleared in 3 days and remained negative thereafter. Investigations revealed that the patient was transfused by a red cell unit harvested in a voluntary donor native of a malaria endemic country. PCR for P. falciparum performed in this donor in the frame of investigations was positive. The patient is alive with a normal blood count 1 year after BMT. PMID- 29573077 TI - Electronic Communication between two [10]cycloparaphenylenes and Bis(azafullerene) (C59 N)2 Induced by Cooperative Complexation. AB - The complex of [10]cycloparaphenylene ([10]CPP) with bis(azafullerene) (C59 N)2 is investigated experimentally and computationally. Two [10]CPP rings are bound to the dimeric azafullerene giving [10]CPP?(C59 N)2 ?[10]CPP. Photophysical and redox properties support an electronic interaction between the components especially when the second [10]CPP is bound. Unlike [10]CPP?C60 , in which there is negligible electronic communication between the two species, upon photoexcitation a partial charge transfer phenomenon is revealed between [10]CPP and (C59 N)2 reminiscent of CPP-encapsulated metallofullerenes. Such an alternative electron-rich fullerene species demonstrates C60 -like ground-state properties and metallofullerene-like excited-state properties opening new avenues for construction of functional supramolecular architectures with organic materials. PMID- 29573078 TI - Characteristics of fall-related traumatic brain injury in older adults. AB - BACKGROUND: Older adults admitted for falls and its complications, including traumatic brain injury (TBI), is increasing. Recent studies have shown that those with falls who presented to the emergency department (ED) had an increased frequency of ED revisits, especially those with head trauma. AIM: To determine the characteristics and predictors of fall-related traumatic brain injury (FRTBI) in older adults. METHODS: Retrospective medical chart review of 339 patients aged 65 years and older admitted for TBI in 2014 due to a fall. Characteristics analysed include demographics, fall circumstances, prior ED visits, polypharmacy, readmission, functional status and specialist outpatient clinic utilisation before and after FRTBI. RESULTS: A total of 339 (37.4%) patients admitted due to FRTBI was 65 years old and older; 112 (33.0%) for subdural haemorrhage (SDH); 227 (67.0%) for head injury (HI), with a mean age of 80 years. A total of 46 (41.1%) patients with SDH and 107 (47.1%) with HI had a previous ED visit within the last year, while 22 (19.6%) of SDH and 49 (21.6%) of HI had hospitalisation 3 months prior to FRTBI. FRTBI was associated with significant decline in activities of daily living, polypharmacy and increased specialist outpatient clinic appointments (P < 0.001). Mortality was 11 (3.2%). Mild cognitive impairment or dementia was significantly associated with admissions for FRTBI, 3.31 (95% confidence interval 1.68-6.51, P = 0.001) using adjusted logistic regression. CONCLUSION: FRTBI is associated with significant functional decline and increased resource utilisation with almost half of the patients having had prior ED visits or hospitalisation. Future studies should focus on falls risk assessment and interventions for high-risk older adults prior to discharge from ED and hospital, and its impact on readmissions due to FRTBI.

PMID- 29573076 TI - Biocatalytic Oxidation Reactions: A Chemist's Perspective. AB - Oxidation chemistry using enzymes is approaching maturity and practical applicability in organic synthesis. Oxidoreductases (enzymes catalysing redox reactions) enable chemists to perform highly selective and efficient transformations ranging from simple alcohol oxidations to stereoselective halogenations of non-activated C-H bonds. For many of these reactions, no "classical" chemical counterpart is known. Hence oxidoreductases open up shorter synthesis routes based on a more direct access to the target products. The generally very mild reaction conditions may also reduce the environmental impact of biocatalytic reactions compared to classical counterparts. In this Review, we critically summarise the most important recent developments in the field of biocatalytic oxidation chemistry and identify the most pressing bottlenecks as well as promising solutions. PMID- 29573080 TI - Functional dimorphic enantiostyly in monomorphic enantiostylous species of the subtribe Cassiinae (Fabaceae-Caesalpinioideae). AB - Monomorphic enantiostylous species produce flowers with a displacement of the style to the left (L) or right (R) on the same individual, and may exhibit different dynamics for the production of these floral types, which may influence levels of selfing. We investigated the production dynamics of L and R floral types in seven species and a variety of monomorphic enantiostylous species of the genera Senna and Chamaecrista. Our hypothesis was that most species present similar proportions of floral morphs each day. Individuals were classified daily over a period of 7 days according to the functional status, i.e. the proportion of floral morphs as functionally L, R or reciprocal (REC, i.e. similar proportions of the two floral morphs), and also according to the number of consecutive days in which they exhibited the same functional status. All species presented low daily flower production. Most species had individuals classified as functionally R, L and REC, and tend to repeat the same functional status over a few days, although they may change functional status during the flowering period. All species exhibited individuals that were classified as functionally reciprocal when both the daily and total number of flowers produced over 7 days was considered. The occurrence of different functional status has not yet been reported in the literature for enantiostylous species. The distinct strategies observed in the dynamics of floral morph production seemed likely to minimise geitonogamy and to favour cross-pollination between individuals (xenogamy). PMID- 29573081 TI - Effect of subconjunctival Bevacizumab injection on the outcome of Ahmed glaucoma valve implantation: a randomized control trial. AB - IMPORTANCE: The effect of subconjunctival Bevacizumab injection on the outcome of Ahmed glaucoma valve (AGV) implantation. BACKGROUND: Evaluation of efficacy and safety of subconjunctival Bevacizumab injection adjunctive to AGV implantation. DESIGN: Prospective and randomized clinical trial. PARTICIPANTS: Fifty eyes of 50 patients with diagnosis of glaucoma that were candidate for AGV surgery were included. METHODS: In 25 eyes, conventional AGV surgery (group 1) and in 25 eyes AGV surgery with subconjunctival Bevacizumab (group 2) was performed by block randomization MAIN OUTCOME MEASURES: The primary outcome measure was surgical success. Outcome measures were compared at postoperative month 3, 6 and 12. RESULTS: Mean age of patients was 58.76 +/- 12.11 and 51.36 +/- 15.44 years in group 1 and 2 respectively (P = 0.06). Mean intraocular pressure (IOP) at baseline was 24.88 +/- 7.62 mmHg in group 1 and 27.52 +/- 8.57 mmHg in group 2 which decreased to15.4 +/- 4.4 mmHg in group 1 and 13.42 +/- 2.9 mmHg in group 2 (P < 0.00) at last follow up. Surgical success was defined in two level: postoperative IOP <= 21 mmHg with at least 20% reduction in IOP (Criterion A), either with no medication (complete success) or with no more than two medications (qualified success) and criterion B with the same definition but the IOP <= 18 mmHg The cumulative success according to criterion A and B was 77.8%, 72.2% in group 1 and 89.5% in group 2, respectively, at the end of follow-up. CONCLUSIONS AND RELEVANCE: Subconjunctival injection of Bevacizumab adjunctive to AGV implantation leads to higher success rate compared with AGV alone in one year follow-up.

AB - BACKGROUND: Lower concentrations of serum albumin appear to be associated with an increased risk of all-cause and cardiovascular mortality, coronary heart disease, heart failure and stroke. However, little is known about the relationship between serum albumin level and prolonged QT interval. AIM: To investigate whether lower serum albumin is associated with prolonged QT interval by recording 12-lead electrocardiography in patients with coronary artery disease and chronic kidney disease. METHODS: This study included 1383 consecutive patients with coronary artery disease and chronic kidney disease (841 with acute coronary syndrome and 542 with elective percutaneous coronary intervention patients) who were enrolled in a disease management programme. Twelve-lead electrocardiography was recorded in each subject. We assessed the relationship between albumin levels (both as a continuous variable and stratified by tertile) at admission and corrected QT (QTc) prolongation. RESULTS: Patients with abnormal QTc interval had lower serum albumin levels than those with normal and borderline QTc intervals. Statistically significant negative associations were observed between serum albumin levels and QTc interval (beta = -0.211, P < 0.0001). Using multivariate and trend analyses, a lower concentration of serum albumin was independently associated with QTc prolongation in both the patients with acute coronary syndrome and elective percutaneous coronary intervention patients. CONCLUSION: Concentrations of serum albumin were significantly lower in the patients with an abnormal QTc interval and were associated with QTc prolongation. Further studies are needed to clarify whether lower serum albumin plays a role in the pathogenesis of QTc prolongation. PMID- 29573084 TI - The clinician factor: Personality characteristics of clinicians and their impact upon clinical outcomes in the management of children and adolescents with type 1 diabetes. AB - OBJECTIVE: The purpose of this study was to estimate clinician qualities that influence metabolic outcomes in youth with type 1 diabetes. RESEARCH DESIGN AND METHODS: Data were gathered over two 3 month periods in a large tertiary diabetes center (1500 patients, 8 clinicians) from patients with type 1 diabetes who received continuous care from each clinician. Data included sex, age, diabetes duration, insulin regimen, body mass index (BMI), insulin dose and episodes of severe hypoglycemia. Clinician data included target blood glucose levels, target glycated hemoglobin (HbA1c), Diabetes Attitude Scale and Big 5 Personality Inventory Scale. Mean HbA1c per clinician was the primary outcome variable. RESULTS: The 8 clinicians saw a total of 464 patients during the first time period, and 603 in the second time period. Lowest to highest mean HbA1c per clinician varied by 0.7%. There were small but statistically significant differences between clinicians with their patients' age at diagnosis, duration of diabetes, age, gender, treatment type and BMI SD score. After controlling for these differences, the clinician characteristics that were associated with lower mean HbA1c were having no lower limit in target HbA1c and being self-reportedly "less agreeable." The impact of these clinician attitudinal traits was equivalent to the combined effects of patient characteristics and treatment type. CONCLUSIONS: There was a significant variation in metabolic outcomes between treating clinicians. After controlling for patient clinical differences, clinician mean HbA1c was associated with lower limit in target HbA1c and being "less agreeable." Clinicians who were more demanding and dogmatic appeared to have better outcomes. PMID- 29573085 TI - Radiomics strategy for glioma grading using texture features from multiparametric MRI. AB - BACKGROUND: Accurate glioma grading plays an important role in the clinical management of patients and is also the basis of molecular stratification nowadays. PURPOSE/HYPOTHESIS: To verify the superiority of radiomics features extracted from multiparametric MRI to glioma grading and evaluate the grading potential of different MRI sequences or parametric maps. STUDY TYPE: Retrospective; radiomics. POPULATION: A total of 153 patients including 42, 33, and 78 patients with Grades II, III, and IV gliomas, respectively. FIELD STRENGTH/SEQUENCE: 3.0T MRI/T1 -weighted images before and after contrast enhanced, T2 -weighted, multi-b-value diffusion-weighted and 3D arterial spin labeling images. ASSESSMENT: After multiparametric MRI preprocessing, high throughput features were derived from patients' volumes of interests (VOIs). The support vector machine-based recursive feature elimination was adopted to find the optimal features for low-grade glioma (LGG) vs. high-grade glioma (HGG), and Grade III vs. IV glioma classification tasks. Then support vector machine (SVM) classifiers were established using the optimal features. The accuracy and area under the curve (AUC) was used to assess the grading efficiency. STATISTICAL TESTS: Student's t-test or a chi-square test were applied on different clinical characteristics to confirm whether intergroup significant differences exist. RESULTS: Patients' ages between LGG and HGG groups were significantly different (P < 0.01). For each patient, 420 texture and 90 histogram parameters were derived from 10 VOIs of multiparametric MRI. SVM models were established using 30 and 28 optimal features for classifying LGGs from HGGs and grades III from IV, respectively. The accuracies/AUCs were 96.8%/0.987 for classifying LGGs from HGGs, and 98.1%/0.992 for classifying grades III from IV, which were more promising than using histogram parameters or using the single sequence MRI. DATA CONCLUSION: Texture features were more effective for noninvasively grading gliomas than histogram parameters. The combined application of multiparametric MRI provided a higher grading efficiency. The proposed radiomic strategy could facilitate clinical decision-making for patients with varied glioma grades.

AB - The reaction of highly Lewis acidic tetra(o-tolyl)diborane(4) with CO afforded a mixture of boraindane and boroxine by the cleavage of the C=O triple bond. 13 C labeling experiments confirmed that the carbon atom in the boraindane stems from CO. Simultaneously, formation of boroxine 3 could be considered as borylene transfer to capture the oxygen atom from CO. The reaction of diborane(4) with t Bu-NC afforded an azaallene, while the reaction with Xyl-NC furnished cyclic compounds by direct C-H borylations. PMID- 29573086 TI - Electrochemical Measurement of Dopamine Release and Uptake in Zebrafish Following Treatment with Carboplatin. AB - Post-chemotherapy cognitive impairment, also known as 'chemobrain,' is a neurological condition in which cognitive function is impaired as a result of cancer chemotherapy treatment. In this work, we used fast-scan cyclic voltammetry (FSCV) to measure electrically evoked dopamine release and uptake in whole brain preparations from zebrafish that have been treated with carboplatin, an agent associated with chemobrain. We administered carboplatin by addition to the fish's tank water or their food. One week of treatment with 100 MUM carboplatin in the water was needed to significantly impair dopamine release (~40 % of control); however, only one day of treatment through the zebrafish's food was needed to cause a similar impairment. Atomic absorption spectroscopy measurements suggested that administration through food resulted in higher initial levels of carboplatin compared to water administration, but water administration resulted in an increase over time. Uptake, determined by modeling stimulated release plots, was unaffected. These results are consistent with our previous findings of diminished neurotransmitter release in rats and support a role for zebrafish in chemobrain related studies. PMID- 29573088 TI - Sensitivity cycling in physically dormant seeds of the Neotropical tree Senna multijuga (Fabaceae). AB - Cycling of sensitivity to physical dormancy (PY) break has been documented in herbaceous species. However, it has not been reported in tree seeds, nor has the effect of seed size on sensitivity to PY-breaking been evaluated in any species. Thus, the aims of this study were to investigate how PY is broken in seeds of the tropical legume tree Senna multijuga, if seeds exhibit sensitivity cycling and if seed size affects induction into sensitivity. Dormancy and germination were evaluated in intact and scarified seeds from two collections of S. multijuga. The effects of temperature, moisture and seed size on induction of sensitivity to dormancy-breaking were assessed, and seasonal changes in germination and persistence of buried seeds were determined. Reversal of sensitivity was also investigated. Fresh seeds were insensitive to dormancy break at wet-high temperatures, and an increase in sensitivity occurred in buried seeds after they experienced low temperatures during winter (dry season). Temperatures <=20 degrees C increased sensitivity, whereas temperatures >=30 degrees C decreased it regardless of moisture conditions. Dormancy was broken in sensitive seeds by incubating them at 35 degrees C. Sensitivity could be reversed, and large seeds were more sensitive than small seeds to sensitivity induction. Seeds of S. multijuga exhibit sensitivity cycling to PY-breaking. Seeds become sensitive during winter and can germinate with the onset of the spring-summer rainy season in Brazil. Small seeds are slower to become sensitive than large ones, and this may be a mechanism by which germination is spread over time. Sensitive seeds that fail to germinate become insensitive during exposure to drought during summer. This is the first report of sensitivity cycling in a tree species.

PMID- 29573090 TI - Charge Transport between Coupling Colloidal Perovskite Quantum Dots Assisted by Functional Conjugated Ligands. AB - Long alkyl-chain capping ligands are indispensable for preparing stable colloidal quantum dots. However, its insulating feature blocks efficient carrier transport among QDs, leading to inferior performance in light-emitting diodes (LEDs). The trade-off between conductivity and colloidal stability of QDs has now been overcome. Methylamine lead bromide (MAPbBr3 ) QDs with a conjugated alkyl-amine, 3-phenyl-2-propen-1-amine (PPA), as ligands were prepared. Owing to electron cloud overlapping and the delocalization effect of conjugated molecules, the conductivity and carrier mobility of PPA-QDs films increased almost 22 times over that of OA-QD films without compromising colloidal stability and photoluminescence. PPA-QDs LEDs exhibit a maximum current efficiency of 9.08 cd A 1 , which is 8 times of that of OA-QDs LEDs (1.14 cd A-1 ). This work provides critical solution for the poor conductivity of QDs in applications of energy related devices.

The goal of the study was to assess the regulatory SNPs (rSNPs) in the human genome and to reveal SRC drivers based on the available chromatin immunoprecipitation sequencing (ChIP-Seq, ChIA-PET) and transcriptional profiling (RNA-Seq) data. We combined positional (locations within genome regulatory elements) and functional (associated with allele specific binding and expression) criteria followed by an analysis using genome wide association studies (GWAS) and minor allele frequency (MAF) datasets. DeSeq2 analysis through 70 CRC patients reinforced the regulatory potential. rSNPs (1,476) that were associated with significant (P < 0.01) allele-specific events resulting in thirty that exhibited a link with CRC according to the MAF and 27, with a risk of malignancy in general according to GWAS. Selected rSNPs may modify the expression of genes for tumor suppressors and the regulators of signaling pathways, including noncoding RNAs. However, the rSNPs from the most represented group affect the expression of genes related to splicing. Our findings strongly suggest that the identified variants might contribute to CRC susceptibility, which indicates that aberrant splicing is one of the key mechanisms for unraveling disease etiopathogenesis and provides useful inputs for interpreting how genotypic variation corresponds to phenotypic outcome.

AB - The biocontrol agent Lysobacter enzymogenes produces polycyclic tetramate macrolactams (PoTeMs), including the antifungal HSAF. To elucidate the biosynthesis of the cyclic systems, we identified eleven HSAF precursors/analogues with zero, one, two, or three rings through heterologous expression of the HSAF gene cluster. A series of combinatorial gene expression and deletion experiments showed that OX3 is the "gatekeeper" responsible for the formation of the first 5-membered ring from lysobacterene A, OX1 and OX2 are responsible for formation of the second ring but with different selectivity, and OX4 is responsible for formation of the 6-membered ring. In vitro experiments showed that OX4 is an NADPH-dependent enzyme that catalyzes the reductive cyclization of 3-dehydroxy alteramide C to form 3-dehydroxy HSAF. Thus, the multiplicity of OX genes is the basis for the structural diversity of the HSAF family, which is the only characterized PoTeM cluster that involves four redox enzymes in the formation of the cyclic system. PMID- 29573093 TI - Sorting of Arabidopsis NRAMP3 and NRAMP4 depends on adaptor protein complex AP4 and a dileucine-based motif. AB - Adaptor protein complexes mediate cargo selection and vesicle trafficking to different cellular membranes in all eukaryotic cells. Information on the role of AP4 in plants is still limited. Here, we present the analyses of Arabidopsis thaliana mutants lacking different subunits of AP4. These mutants show abnormalities in their development and in protein sorting. We found that growth of roots and etiolated hypocotyls, as well as male fertility and trichome morphology are disturbed in ap4. Analyses of GFP-fusions transiently expressed in mesophyll protoplasts demonstrated that the tonoplast (TP) proteins MOT2, NRAMP3 and NRAMP4, but not INT1, are partially sorted to the plasma membrane (PM) in the absence of a functional AP4 complex. Moreover, alanine mutagenesis revealed that in wild-type plants, sorting of NRAMP3 and NRAMP4 to the TP requires an N terminal dileucine-based motif. The NRAMP3 or NRAMP4 N-terminal domain containing the dileucine motif was sufficient to redirect the PM localized INT4 protein to the TP and to confer AP4-dependency on sorting of INT1. Our data show that correct sorting of NRAMP3 and NRAMP4 depends on both, an N-terminal dileucine based motif as well as AP4.

AB - The iridium(III)/copper(II)-catalyzed dehydrogenative coupling of salicylaldehydes with internal alkynes proceeds efficiently under atmospheric oxygen through aldehyde C-H bond cleavage and decarbonylation. A variety of benzofuran derivatives can be synthesized by the environmentally benign procedure. DFT calculations suggest that this unique transformation involves the facile deinsertion of CO in the key metallacycle intermediate, which is in marked contrast to the corresponding rhodium(III) catalysis that leads to CO-retentive chromone derivatives. PMID- 29573095 TI - Myoepithelial carcinoma of the nasopharynx: Rare case report with clinicopathologic and immunohistochemical features review of literature. AB - BACKGROUND: Myoepithelial carcinoma is a rare salivary carcinoma, which most often arises from the major salivary glands. Only a few cases of myoepithelial carcinoma of the nasopharynx have been reported, thus, the treatment guideline and prognosis remain undefined. METHODS: We reported a case of nasopharyngeal myoepithelial carcinoma in a 31-year-old man. The tumor cells showed specific cell types and arrangements histologically, which were immunoreactive with myoepithelial markers. The patient received surgical excision with transpalatal approach. A literature review of previous cases was also presented. RESULTS: The patient reflected residual tumor 4 weeks later. After concurrent chemoradiotherapy (CRT), the tumor reduced and remained stable without signs of progression. CONCLUSION: The nasopharyngeal mass with spindled, plasmacytoid, epithelioid, and clear cell types, was suggested to raise the suspicion of myoepithelial carcinoma in order to diagnose and treat early. The wide surgical excision followed by optimal adjuvant therapy might offer a mode of treatment with better survival results. PMID- 29573096 TI - Electrochemical Responsive Superhydrophilic Surfaces of Polythiophene Derivatives towards Cell Capture and Release. AB - Highly efficient cell capture and release with low background are urgently required for early diagnosis of diseases such as cancer. Herein, we report an electrochemical responsive superhydrophilic surface exhibiting specific cell capture and release with high yields and extremely low nonspecific adhesion. Through electrochemical deposition, 3-substituted thiophene derivatives are deposited onto indium tin oxide (ITO) nanowire arrays with 4-n nonylbenzeneboronic acid (BA) as dopant, fabricating the electrochemical responsive superhydrophilic surfaces. The molecular recognition between sialic acids over-expressed on the cell membrane and doped BAs endows the electrochemical responsive surfaces with the ability to capture and release targeted cancer cells. By adjusting the substituent group of thiophene derivatives, the surface wettability can be readily regulated and further utilized for reducing nonspecific cell adhesion. Significantly, the released cells still maintain a high proliferation ability, which indicates that the applied potential does not significantly harm the cells. Therefore, these results may provide a new strategy to achieve advanced functions of biomedical materials, such as low nonspecific adhesion. PMID- 29573097 TI - Ultrastable Imine-Based Covalent Organic Frameworks for Sulfuric Acid Recovery: An Effect of Interlayer Hydrogen Bonding. AB - A rapid and scalable synthesis of six new imine-linked highly porous and crystalline COFs is presented that feature exceptionally high chemical stability in harsh environments including conc. H2 SO4 (18 m), conc. HCl (12 m), and NaOH (9 m). This is because of the presence of strong interlayer C-H???N hydrogen bonding among the individual layers, which provides significant steric hindrance and a hydrophobic environment around the imine (-C=N-) bonds, thus preventing their hydrolysis in such an abrasive environment. These COFs were further converted into porous, crystalline, self-standing, and crack-free COF membranes (COFMs) with extremely high chemical stability for their potential applications for sulfuric acid recovery. The as-synthesized COFMs exhibit unprecedented permeance for acetonitrile (280 Lm-2 h-1 bar-1 ) and acetone (260 Lm-2 h-1 bar-1 ). PMID- 29573098 TI - Rosiglitazone lowers resting and blood pressure response to exercise in men with type 2 diabetes: A 1-year randomized study. AB - AIMS: We aimed to determine the effect of 1-year treatment with the insulin sensitizer peroxisome proliferator-activated receptor (PPAR)-gamma agonist rosiglitazone on exercise capacity and blood pressure (BP) response to exercise in men with coronary artery disease (CAD) and type 2 diabetes (T2D). MATERIALS AND METHODS: A total of 116 men (age, 64 +/- 7 years; body mass index, 30.0 +/- 4.4 kg/m2 ) with CAD and T2D were randomized to receive rosiglitazone or placebo for 1 year. Exercise capacity (VO2peak ) and BP response to exercise were assessed with a maximal treadmill test, prior to the intervention and at 1-year follow-up. Exercise-induced hypertension (EIH) was defined as maximal systolic BP >= 220 mm Hg and/or diastolic BP >= 100 mm Hg. RESULTS: PPAR-gamma agonist treated patients showed improvements in fasting glucose, HbA1c and insulin sensitivity (Homeostasis model assessment of insulin resistance [HOMA-IR]) (all P < .05). Resting BPs, maximal exercise diastolic BP and resting rate-pressure product (RPP) were all reduced in the PPAR-gamma agonist group (P < .05). Maximal exercise duration was unchanged. T2D patients who displayed the greatest improvement in insulin sensitivity (HOMA-IR) under PPAR-gamma agonist treatment experienced a greater reduction in exercise BP and RPP (P < .05). The proportion of men with EIH decreased in the PPAR-gamma agonist group during follow-up (39.00% +/- 0.06% vs 21.00% +/- 0.05%). In the subgroup with EIH that was treated with a PPAR-gamma agonist, resting and exercise diastolic BP, as well as resting RPP, were all reduced at 1-year follow-up (P < .05). CONCLUSIONS: The insulin sensitizer rosiglitazone has a beneficial effect on resting and BP response to exercise in men with CAD and T2D, especially in those with an exaggerated BP response to exercise. PMID- 29573099 TI - Nursing history as philosophy-towards a critical history of nursing. AB - Mainstream nursing history often positions itself in opposition to philosophy and many nursing historians are reticent of theorizing. In the quest to illuminate the lives of nurses and women current historical approaches are driven by reformist aspirations but are based on the conception that nursing or caring is basically good and the timelessness of universal values. This has the effect of essentialising political categories of identity such as class, race and gender. This kind of history is about affirmation rather than friction and about the conservation of memory and musealization. In contrast, we will focus on how we imagine nursing history could be used as a philosophical, critical perspective to challenge the ongoing transformations of our societies. Existing reality must be confronted with strangeness and the historically different can assume the function of this counterpart, meaning present and past must continuously be set in relation to each other. Thus, critical history is always the history of the present but not merely the pre-history of the present - critique must rather present different realities and different certainties. In this paper, we use this approach to discuss the implementation of the nursing process (NP) in Germany. The nursing process appears to be a technology that helped to set up an infrastructure - or assemblage - to transform nursing interventions into a commodity exchangable between consumers and nurses in a free market. In our theoretical perspective, we argue that NP was a step in the realization of the German ordoliberal program, a specific variety of neoliberalism. In order to implement market-orientation in the healthcare system it was necessary to transform hospitals into calculable spaces and to make all performances in the hospital calculable. This radically transformed not just the systems, but the ways in which nurses and patients conveived of themselves. PMID- 29573100 TI - Trimethylsilyl-Protected Alkynes as Selective Cross-Coupling Partners in Titanium Catalyzed [2+2+1] Pyrrole Synthesis. AB - Trimethylsilyl (TMS)-protected alkynes served as selective alkyne cross-coupling partners in titanium-catalyzed [2+2+1] pyrrole synthesis. Reactions of TMS protected alkynes with internal alkynes and azobenzene under the catalysis of titanium imido complexes yielded pentasubstituted 2-TMS-pyrroles with greater than 90 % selectivity over the other nine possible pyrrole products. The steric and electronic effects of the TMS group were both identified to play key roles in this highly selective pyrrole synthesis. This strategy provides a convenient method to synthesize multisubstituted pyrroles as well as an entry point for further pyrrole diversification through facile modification of the resulting 2 silyl pyrrole products, as demonstrated through a short formal synthesis of the marine natural product lamellarin R. PMID- 29573101 TI - Improving life expectancy of patients with scleroderma: results from the South Australian Scleroderma Register. AB - BACKGROUND: Scleroderma is a rare connective tissue disorder characterised by inflammation, vasculopathy and excessive fibrosis. Patients with scleroderma are known to have decreased life expectancy. AIM: To investigate changes in life expectancy in patients with scleroderma over a 30-year period. METHODS: Utilising the South Australian Scleroderma Register, deceased patients were identified. We examined changes in age of death and duration of disease in these patients over three time periods: 1985-1994, 1995-2004 and 2005-2015. Analyses of scleroderma subtypes were performed, and comparisons were made to the general South Australian population. RESULTS: A total of 413 deceased patients was identified. Females were overrepresented 315 to 98; 265 had limited scleroderma, 90 diffuse and 22 overlap disease. Over 30 years, the mean age of death improved from 66.4 to 74.5 years (P < 0.001). Duration of disease improved from 12.1 to 22.9 years (P < 0.001). Improvement in survival was seen in limited (P = 0.001), diffuse (P = 0.04) and overlap (P = 0.04) subgroups. The increase in survival was only seen for female (9.8 +/- 4.2 years) but not male (1.4 +/- 6.7 years) patients. CONCLUSION: Over the last 30 years, survival has significantly improved for female but not male patients. As no disease-modifying drugs have consistently been shown to alter disease course, this improvement is likely attributable to general improvements in medical care, including that of scleroderma-related complications. While the life expectancy for limited disease is now close to that of the general population, patients with diffuse and overlap disease continue to suffer from significant early mortality. PMID- 29573103 TI - Efficacy and adverse effects of topical chloramphenicol ointment use for surgical wounds: a systematic review. AB - BACKGROUND: Chloramphenicol ointment is often used in plastic and dermatologic surgery as a topical antibiotic for surgical wounds, but evidence regarding its efficacy and side effects is lacking. In addition, anecdotal fear of aplastic anaemia exists from the oral use of this drug. We performed a systematic review of the literature to assess the efficacy and side effect profile of topical chloramphenicol ointment on non-ocular surgical wounds. METHODS: A systematic search of MEDLINE, EMBASE and the Cochrane Library from inception until 4 September 2017 was undertaken. Clinical studies of topical chloramphenicol ointment use on surgical wounds were included. Studies looking only at ocular use or those not available in full text or English were excluded. The review was conducted adhering to PRISMA guidelines. RESULTS: After full-text review, five articles were included. Two were randomized controlled trials, one was retrospective case control and two were case studies. There was evidence that chloramphenicol ointment use on surgical wounds produced a non-statistically significant reduction in infection rates. Delayed hypersensitivity and acute oesophagitis were noted as potential side effects of non-ocular topical use. Aplastic anaemia was not reported. CONCLUSION: There is a paucity of clinical data regarding the use of topical chloramphenicol ointment on surgical wounds. Further randomized controlled trials may be beneficial in order to support or refute its use in this setting. PMID- 29573102 TI - Day case hernia repair: weak evidence or practice gap? AB - BACKGROUND: Analysis of a private insurer's administrative data set revealed significant variation in the length of hospital stay following hernia surgery. OBJECTIVES: This review examined factors influencing the performance of day surgery for inguinal, femoral and umbilical hernia repair in adults. DATA SOURCES: A systematic literature search was conducted in the PubMed, Embase and Cochrane Library databases to identify studies and clinical practice guidelines (CPGs) comparing same day hernia surgery to surgery followed by an overnight stay. REVIEW METHODS: Screening of studies by abstract and full text was completed by a single researcher and checked by a second. Studies were selected for inclusion based on a step-wise approach across three phases. RESULTS: Limited evidence from one systematic review, and three case series studies including 3213 patients found that same day hernia surgery was as safe and effective as an overnight stay. All identified CPGs recommended a same day procedure for most patients. Two case series studies reported that 3-8% of patients were ineligible for day procedures due to medical reasons; however, the characteristics of patients, in general, which are not suitable, have not been adequately investigated. CONCLUSIONS: Day surgery for groin hernia repair is safe and effective for most patients. However, evidence-based support is only one of many factors that may contribute to the uptake of day surgery in Australia. There is an opportunity for key stakeholders across the private healthcare system to deliver an equally effective but more sustainable and affordable hernia care by increasing the day surgery rates. PMID- 29573104 TI - Transvesical robot-assisted simple prostatectomy with 360 degrees circumferential reconstruction: step-by-step technique. AB - OBJECTIVE: To present the step-by-step technique of a 360 degrees mucosal reconstruction after transvesical robot-assisted simple prostatectomy (RASP). PATIENT AND METHODS: We analysed the first 23 consecutive patients who underwent RASP using our 360 degrees reconstruction between December 2015 and October 2017. After transperitoneal intravesical adenoma enucleation, a circumferential 360 degrees reconstruction is performed. The first suture is placed at the 9 o'clock position and the edge of the urethra and bladder mucosa is approximated using 2-0 barbed suture. The reconstruction is continued counter-clockwise and the bladder mucosa is approximated to the urethra circumferentially. RESULTS: The mean (sd) operating time was 160.6 (28.1) min and the estimated blood loss was 98.6 (99.8) mL. No patients required conversion to open surgery. No intra operative or postoperative transfusions were needed. No intra-operative complications occurred. The mean (sd) length of hospital stay was 2.1 (0.6) days. One postoperative complication was reported (respiratory distress in a patient with chronic obstructive pulmonary disease, requiring intensive care unit admission). CONCLUSION: Our 360 degrees reconstruction during RASP is feasible and safe. The aim of the technique is to minimize use of electrocautery and decrease the raw surface area on the prostate capsule. This technical modification could potentially lessen postoperative bleeding after RASP and therefore the need for continuous bladder irrigation. In addition, it could potentially lead to mitigation of burning and irritative postoperative symptoms. Longer follow-up and comparative studies of different RASP techniques are still needed. PMID- 29573105 TI - What to do with the rectal stump during sphincter preserving rectal cancer resection with end colostomy: a collaborative snapshot study. AB - AIM: Low Hartmann's resection (LHR) and intersphincteric abdominoperineal excision (iAPR) are both feasible options in the treatment of rectal cancer when restoration of bowel continuity is not desired. The aim of this study was to compare the incidence of pelvic abscess and associated need for re-intervention and readmission after LHR and iAPR. METHOD: From a snapshot research project in which all rectal cancer resections from 71 Dutch hospitals in 2011 were evaluated, patients who underwent LHR or iAPR were selected. RESULTS: A total of 185 patients were included: 139 LHR and 46 iAPR. No differences in baseline characteristics were found except for more multivisceral resections in the iAPR group (22% vs 10%; P = 0.041). Pelvic abscesses were diagnosed in 17% of the LHR group after a median of 21 days (interquartile range 10-151 days), compared to 11% in the iAPR group (P = 0.352) after a median of 90 days (interquartile range 44-269 days; P = 0.102). All 28 patients with a pelvic abscess underwent at least one re-intervention. Four patients (9%) in the iAPR group and nine (7%) after LHR were readmitted because of a pelvic abscess over a median 39 months of follow-up. CONCLUSION: This cross-sectional multicentre study suggests that cross-stapling and intersphincteric resection of the rectal stump, during non-restorative rectal cancer resection, are associated with an equal risk of pelvic abscess formation and have a similar need for re-intervention and readmission. PMID- 29573106 TI - The effect of low-intensity extracorporeal shockwave therapy in an obesity associated erectile dysfunction rat model. AB - OBJECTIVES: To investigate the feasibility of the Zucker fatty (ZF) rat as a model for research in to obesity-associated erectile dysfunction (OAED) and to determine the effect of low-intensity extracorporeal shockwave therapy (Li-ESWT) on penile tissue and function in these rats. MATERIALS AND METHODS: Eight new born male Zucker lean (ZL group) rats (ZUC-Leprfa 186) and 16 new-born male ZF rats (ZUC-Leprfa 185) were injected with 5-ethynyl-2'-deoxyuridine (EdU) at birth to identify and monitor endogenous stem cells. Insulin tolerance testing was performed at 10 weeks of age. Beginning at 12 weeks of age, eight ZF rats were kept as controls, and the remaining eight ZF rats were treated with Li-ESWT (0.02 mJ/mm2 , 3 Hz, 500 pulses; ZF + SW group) twice a week for 4 weeks. Following a 1 week washout period, erectile function was evaluated by measuring intracavernosal pressure (ICP) and mean arterial pressure (MAP). Penile tissues were then harvested for histological study to assess smooth muscle/collagen content and endothelium content in the corpora cavernosum. LipidTOXTM staining was used to evaluate lipid accumulation. EdU, as a marker of cell activation, and phosphorylated histone 3 (H3P), as a marker of cell mitosis, were also assessed. RESULTS: The ICP/MAP indicated that erectile function was severely impaired in the ZF group as compared with the ZL group. In the ZF + SW group, erectile function was significantly improved (P < 0.05). Muscle atrophy was seen in the ZF group, while Li-ESWT increased the muscle content in ZF + SW group. Moreover, the penile endothelium was damaged in the ZF group, and Li-ESWT enhanced the regeneration of endothelial cells (P < 0.01) in the ZF + SW group. Lipid accumulation was seen in the penile tissue of ZF rats. Li-ESWT significantly reduced both the amount and the distribution pattern of LipidTOX, suggesting decreased overall lipid infiltration. Furthermore, Li-ESWT increased EdU-positive cells and markedly enhanced the phosphorylation level of H3P at Ser-10 in the ZF + SW group. Most H3P-positive cells were located within smooth muscle cells, with some located in the endothelium suggesting that these tissues are the reservoirs of penile stem/progenitor cells. CONCLUSION: ZF rats can serve as an animal model in which to study OAED. This study reveals that obesity impairs erectile function by causing smooth muscle atrophy, endothelial dysfunction, and lipid accumulation in the corpus cavernosum. Li-ESWT restored penile haemodynamic parameters in the ZF rats by restoring smooth muscle and endothelium content and reducing lipid accumulation. The underlying mechanism of Li-ESWT appears to be activation of stem/progenitor cells, which prompts cellular proliferation and accelerates penile tissue regeneration. Our findings are of interest, not just as a validation of this emerging treatment for erectile dysfunction, but also as a novel and potentially significant method to modulate endogenous stem/progenitor cells in other disease processes.

AB - BACKGROUND: Post-operative pain is a major issue following excisional haemorrhoidectomy. Although metronidazole by both oral and topical administration routes has been shown to reduce pain after haemorrhoidectomy, its use remains a contentious issue. This systematic review and meta-analysis aims to investigate the effect of metronidazole on post-operative pain after excisional haemorrhoidectomy. METHODS: A systematic review of the literature was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) published in PubMed/MEDLINE, EMBASE, CENTRAL and CINAHL, from inception to December 2016 were retrieved. The primary outcome investigated was post-operative pain reported as visual analogue score (VAS). Secondary outcomes were analgesia use, complications and time to return to normal activity. Meta-analysis was performed using Review Manager version 5.3 software. RESULTS: Nine randomized controlled trials including 523 patients were included in the final analysis. Five studies used oral administration and four used topical. Meta-analysis showed that post-operative VAS of patients receiving metronidazole by either route was significantly less than those in comparison groups. VAS means decreased at all the time points for both oral and topical metronidazole. Topical and oral routes of administration were not compared in any study. There was no increase in complication rates and return to normal activity was significantly earlier for patients receiving metronidazole (-4.49 days; 95% confidence interval [-7.70, -1.28]; P = 0.006). CONCLUSIONS: Both topical and oral metronidazole reduce post-operative pain without an increase in complication rates and result in an earlier return to normal activity. Further work is required to determine which the optimum route of administration is. PMID- 29573109 TI - Management of chronic pain and opioid dependence with buprenorphine/naloxone. PMID- 29573110 TI - SGLT2 inhibitor plus DPP-4 inhibitor as combination therapy for type 2 diabetes: A systematic review and meta-analysis. AB - To assess the efficacy and safety of sodium-glucose co-transporter 2 (SGLT2) inhibitors plus a dipeptidyl peptidase-4 (DPP-4) inhibitor in patients with type 2 diabetes mellitus (T2DM), we performed a systematic review and meta-analysis of 14 randomized controlled trials (RCTs) involving 4828 patients. Compared with a DPP-4 inhibitor, SGLT2 inhibitor/DPP-4 inhibitor combination therapy was significantly associated with a decrease in glycaemic control (HbA1c, -0.71%; fasting plasma glucose [FPG], -25.62 mg/dL; postprandial plasma glucose, -44.00 mg/dL), body weight (-2.05 kg) and systolic blood pressure (-5.90 mm Hg), but an increase in total cholesterol (TC) of 3.24%, high-density lipoprotein of 6.15% and low-density lipoprotein of 2.55%. Adding a DPP-4 inhibitor to an SGLT2 inhibitor could reduce HbA1c by -0.31%, FPG by -8.94 mg/dL, TC by -1.48% and triglycerides by -3.25%. Interestingly, low doses of an SGLT2 inhibitor in the combination has similar or even better efficacy in some aspects than high doses. Similar adverse events were observed for the combination therapy, with the exception of genital infection vs DPP-4 inhibitor (risk ratio [RR], 5.31) and consistent genital infection vs an SGLT2 inhibitor (RR, 0.61). Further studies are warranted to confirm these results. PMID- 29573111 TI - A tale of two cities: prehospital intubation with or without paralysing agents for traumatic brain injury. AB - BACKGROUND: The role of prehospital endotracheal intubation (PETI) for traumatic brain injury is unclear. In Victoria, paramedics use rapid sequence induction (RSI) drugs to facilitate PETI, while in New South Wales (NSW) they do not have access to paralysing agents. We hypothesized that RSI would both increase PETI rates and improve mortality. METHODS: Retrospective comparison of adult primary admissions (Glasgow Coma Scale <9 and abbreviated injury scale head and neck >2) to either Victorian or NSW trauma centre, which were compared with univariate and logistic regression analysis to estimate odds ratio for mortality and intensive care unit (ICU) length of stay. RESULTS: One hundred and ninety-two Victorian and 91 NSW patients did not differ in: demographics (males: 77% versus 79%; P = 0.7 and age: 34 (18-88) versus 33 (18-85); P = 0.7), Glasgow Coma Scale (3 (3-8) versus 5 (3-8); P = 0.07), and injury severity score (38 (26-75) versus 35 (18 75); P = 0.09), prehospital hypotension (15.4% versus 11.7%; P = 0.5) and desaturation (14.6% versus 17.5%; P = 0.5). Victorians had higher abbreviated injury scale head and neck (5 (4-5) versus 5 (3-6); P = 0.04) and more often successful PETI (85% versus 22%; P < 0.05). On logistic regression analysis, mortality did not differ among groups (31.7% versus 26.3%; P = 0.34; OR = 0.84; 95% CI: 0.38-1.86; P = 0.67). Among survivors, Victorians had longer stay in ICU (364 (231-486) versus 144 (60-336) h), a difference that persisted on gamma regression (effect = 1.58; 95% CI: 1.30-1.92; P < 0.05). CONCLUSION: Paramedics using RSI to obtain PETI in patients with traumatic brain injury had a higher success rate. This increase in successful PETI rate was not associated with an improvement in either mortality rate or ICU length of stay.

AB - One of the main aims of treatment after successful recovery from anorexia nervosa (AN) is to prevent a relapse. The Guideline Relapse Prevention (GRP) Anorexia Nervosa offers a structured approach to relapse prevention. This study explores how patients and their parents experience working with the guideline. It also describes the factors that support or hinder successful application of the guideline. A descriptive qualitative research design was chosen involving in depth interviews with seventeen patients with anorexia nervosa and six sets of parents. Patients and family members were generally satisfied with the support provided by the GRP. It contributed significantly to a better understanding of the personal process of relapse. Patients and families valued being able to keep in touch with their professional during the aftercare programme. The GRP supports the patient's use of self-management strategies for relapse prevention. PMID- 29573114 TI - MiR-127-3p inhibits cell growth and invasiveness by targeting ITGA6 in human osteosarcoma. AB - Osteosarcoma (OS) is one of the most universal malignant bone tumors that occur mostly in children and adolescents. This study aimed to investigate the roles of miR-127-3p and integrin subunit-alpha 6 (ITGA6) in OS proliferation, apoptosis, invasion and migration, and to explore the possible molecular mechanism and target relationship. By conducting quantitative real-time polymerase chain reaction (qRT-PCR) and western blot, the microRNA (miRNA) and protein expressions of miR-127-3p and ITGA6 in both tissues and cells were determined. The expression of apoptosis and migration related were also detected by western blot. The target relationship between miR-127-3p and ITGA6 was predicted by TargetScan and verified by dual-luciferase reporter assay. The biological functions of miR-127 3p and ITGA6 in OS were investigated by following experiments: cell counting kit 8 (CCK-8) and colony formation assays to inspect cell proliferation, flow cytometry, and caspase 3 activity assay to examine apoptosis, and transwell and wound healing assays to analyze invasion and migration. Significant down regulation of miR-127-3p and up-regulation of ITGA6 was found out in OS tissues and cells. ITGA6 was proved to be the downstream target gene of miR-127-3p and functioned as a tumor promotor in OS, while miR-127-3p restrained deterioration of OS by suppressing cell viability, reducing migration and invasion, and promoting apoptosis. MiR-127-3p suppressed proliferation, invasion, and migration while stimulated apoptosis of OS cells through knocking down ITGA6. (c) 2018 IUBMB Life, 70(5):411-419, 2018. PMID- 29573115 TI - Accuracy and consistency of electronic root canal length determination with electrically isolating rubber stoppers. AB - The aim of this study was to investigate the influence of an isolating silicone stopper on the measuring accuracy and display consistency of three electrometric apex locators. The length of the canal to the major foramen was determined electrometrically using an ISO size 10 file in 20 extracted teeth each with natural crowns (Group I), amalgam fillings (Group II) or base-metal crowns (Group III), The measurements were performed with isolating or conventional silicone stoppers using three different apex locators with a four-level scale consistency rating. The use of isolating stoppers resulted in a more consistent display than with conventional stoppers, independent of the presence or type of coronal restoration (P = 0.017). Across all coronal restorations, the position of the major foramen could be determined to within +/- 0.5 mm without significant differences (P = 0.79) using conventional and isolating stoppers. The use of modified isolating stoppers provides a significant increase in display consistency.

AB - AIM: Pain is an increasingly common phenomenon as people age; pain over a long period can result in limited functioning. The present study investigated the impacts of general and multisite-specific pain on activities of daily living and physical performance among older adults. METHODS: Data were analyzed from the English Longitudinal Study of Ageing, a representative sample of the population aged >=50 years. Face-to-face interview and nurse records were used from waves 2 6 (2004-2012) for analyses. General and site-specific pain (back, hip and knee) were measured biennially between 2004 and 2008 (n = 5010). Impaired activity of daily living and physical performance measures (chair rise and grip strength) between 2008 and 2012 were aggregated across assessments as outcomes. Multinomial logistic regressions were used for the former and linear regression for the latter, adjusting for potential covariates. RESULTS: General pain (moderate-to severe) was prevalent, with close to one-quarter of participants reporting pain at least twice during the follow-up period. Multisite pain reports were strong predictors of subsequent limited activities of daily living (adjusted odds ratio range 1.86-3.97 for back and hip, 2.04-4.19 for back and knee, and 2.08-5.16 for hip and knee). Persistent pain was also strongly associated with worse physical performance outcomes. CONCLUSIONS: Our data confirm the longitudinal impacts of persistent pain among older adults. The findings highlight the value of monitoring and management of both general and site-specific pain in order to promote sustained independence at older ages.

AB - Adult forensic mental health services provide care and treatment to individuals with complex offending and mental health histories. However, little attention has been paid to the parents of those receiving care within them. This research explored the experiences of parents with an adult son or daughter with mental illness in a medium secure mental health unit. Transcripts from semi-structured interviews were analysed using interpretative phenomenological analysis. This led to the identification of three superordinate themes: 'Something's not right' onset of mental distress; 'It's a terrible battle'-relating with professionals; and 'A very sad fact of life'-caring with no end in sight were identified which together contained nine subordinate themes. The onset of the mental distress was narrated as overwhelming, frightening, and confusing with experiences of violence. Services were seen as invalidating, and interactions with them characterized as a battle. Poor information and involvement were a common experience. Whilst diagnosis was a relief to some, the ongoing sense of loss and burden were clear. Staying connected and hopes for the future were also described. It is clear from this study that mental health services need to do more to engage and foster trust with parents from the outset and to offer support for this group. If secure services were to view parents as 'forensic carers', this may help improve respect and engagement between services and carers. Services and policymakers should strive to foster high-quality family involvement as part of developing social inclusion.

AB - The effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on risk of stroke have not been conclusively established. Therefore, we conducted a meta analysis to evaluate the effects of SGLT2 inhibitors on stroke risk in patients with type 2 diabetes mellitus (T2DM) by searching available randomized trials in PubMed, Embase, CENTRAL, Web of Science, Scopus and ClinicalTrials.gov databases. We identified 32 eligible trials involving 75 540 participants. The incidence of stroke in groups receiving SGLT2 inhibitor monotherapy or combination therapy did not differ significantly from that in control groups, with a relative risk (RR) of 1.01 and 1.0, respectively. Three SGLT2 inhibitors were tested, with similar RR values (canagliflozin [RR, 0.91], dapagliflozin [RR, 0.99] and empagliflozin [RR, 1.03]). Subgroup analyses showed that RR values were not affected by gender, age, diabetes duration, BMI or HbA1C levels, but Black patients had a lower incidence of stroke than White or Asian patients. This meta-analysis indicated that SGLT2 inhibitor therapy did not increase stroke incidence, and no significant differences in stroke risk were observed among 3 SGLT2 inhibitors (class effect). However, the small racial disparity requires further study and confirmation. PMID- 29573119 TI - Determine and compare the viewpoints of nurses, patients and their relatives to workplace violence against nurses. AB - AIM: The present study aims to assess the perception of nurses, patients and their relatives regarding the nature of workplace violence against nurses. BACKGROUND: Workplace violence adversely affects the health, well-being and safety of nurses and the quality of nursing care. METHODS: In the present descriptive comparative study, the nature of violence was assessed using a modified and validated International Labor Office, the International Council of Nurses, World Health Organization, and Public Services International Questionnaire. RESULTS: Nurses, patients and relatives reported verbal abuse as the most common and sexual violence as the least common type of violence against nurses. Nurses mostly blamed factors associated with patients and their relatives as the cause of violence, whereas patients and their relatives blamed social factors. CONCLUSIONS: This study shows that violence is significantly prevalent in clinical settings, but its nature is differently perceived by nurses, patients and their relatives. This phenomenon requires further studies because knowledge of the causes of this difference could help to reduce and control violence. IMPLICATIONS FOR NURSING MANAGEMENT: It is necessary that nursing managers inform nurses about protocols for reporting all such cases in order to collect information, and based on a clear procedure, actively pursue reported cases and take the necessary measures to prevent violence against nurses.

AB - We challenge the suggestion by Sample et al. (2015) that a depth of 305 cm (10 ft) exceeds the depth of biological activity in soils at the Hanford Site, Washington, USA, or similar sites. Instead, we support the standard point of compliance, identified in the Model Toxics Control Act in the state of Washington, which specifies a depth of 457 cm (15 ft) for the protection of both human and ecological receptors at the Hanford Site. Our position is based on additional information considered in our expanded review of the literature, the influence of a changing environment over time, plant community dynamics at the Hanford Site, and inherent uncertainty in the Sample et al.

AB - BACKGROUND: As high-dose-rate (HDR) brachytherapy can preferentially spare normal anatomic structures surrounding the radiation target, we report on our experience using this technique in head and neck cancer reirradiation. METHODS: Twenty patients received HDR brachytherapy reirradiation with curative or palliative intent from 2010-2015. Clinical and toxicity outcomes were recorded. Actuarial outcomes were calculated using Kaplan-Meier analysis. RESULTS: For curative treatment, actuarial 2-year rates of local control and overall survival (OS) were 73% and 56%, respectively. Palliatively, a 6-month local control rate of 65% was seen. Age >70 years was associated with poorer OS (P = .042). Prior salvage resection showed a trend toward improved local control and OS (P = .069 and P = .063, respectively). Thirty-three percent had grade 3 to 4 late toxicities. CONCLUSION: Curative-intent HDR brachytherapy reirradiation can provide excellent local control and encouraging OS. Given the late toxicity rates, patient selection is essential, with particular utility for younger patients or those treated with salvage resection.

PMID- 29573123 TI - The association between psychological factors and breastfeeding behaviour in women with a body mass index (BMI) >=30 kg m-2 : a systematic review. AB - Breastfeeding can play a key role in the reduction of obesity, but initiation and maintenance rates in women with a body mass index (BMI) of >=30 kg m-2 are low. Psychological factors influence breastfeeding behaviours in the general population, but their role is not yet understood in women with a BMI >=30 kg m-2 . Therefore, this review aimed to systematically search and synthesize the literature, which has investigated the association between any psychological factor and breastfeeding behaviour in women with a BMI >=30 kg m-2 . The search identified 20 eligible papers, reporting 16 psychological factors. Five psychological factors were associated with breastfeeding behaviours: intentions to breastfeed, belief in breast milk's nutritional adequacy and sufficiency, belief about other's infant feeding preferences, body image and social knowledge. It is therefore recommended that current care should encourage women to plan to breastfeed, provide corrective information for particular beliefs and address their body image and social knowledge. Recommendations for future research include further exploration of several psychological factors (i.e. expecting that breastfeeding will enhance weight loss, depression, anxiety and stress) and evidence and theory-based intervention development. PMID- 29573124 TI - The role of lipids in host-pathogen interactions. AB - Innate immunity relies on the effective recognition and elimination of pathogenic microorganisms. This entails sequestration of pathogens into phagosomes that promptly acquire microbicidal and degradative properties. This complex series of events, which involve cytoskeletal reorganization, membrane remodeling and the activation of multiple enzymes, is orchestrated by lipid signaling. To overcome this immune response, intracellular pathogens acquired mechanisms to subvert phosphoinositide-mediated signaling and use host lipids, notably cholesterol, as nutrients. We present brief overviews of the role of phosphoinositides in phagosome formation and maturation as well as of cholesterol handling by host cells, and selected Salmonella, Shigella, Chlamydia and Mycobacterium tuberculosis to exemplify the mechanisms whereby intracellular pathogens co-opt lipid metabolism in host cells.

AB - The long-term impact of dipeptidyl peptidase-4 (DPP-4) inhibition is unknown, and there are concerns about the influence of DPP-4 inhibition on carcinogenesis of the pancreas and thyroid. As DPP-4 is a rather unselective enzyme present in many tissues, we focused on all specific cancer types. PubMed and EMBASE were searched between January 2005 and April 2017 to identify studies comparing DPP-4 inhibitors with either placebo or active drugs on cancer risk. Studies were included if they reported on at least one specific cancer outcome and had a follow-up of at least 1 year after start of drug use. Methodological quality of the studies was assessed by the Cochrane Collaboration's tool and the Newcastle Ottawa Scale. Twenty-five studies met the inclusion criteria (12 randomized controlled trials and 13 observational studies). Sample sizes of the DPP-4 inhibitor groups ranged from 29 to 8212 patients for randomized controlled trials and from 2422 to 71 137 patients for observational studies. Mean age ranged from 51 to 76 years, and mean follow-up was 1.5 years. None of the pooled (sensitivity) analyses, except the observational studies studying breast cancer (hazard ratio [95% CI]: 0.76 [0.60-0.96]), showed evidence for an association between DPP-4 inhibitors and site-specific cancer. Also for pancreatic and thyroid cancer, no statistically significant risk was found. Based on the current literature, it is not possible to conclude whether DPP-4 inhibitors were associated with an increased risk of site-specific cancer. Future studies should address the methodological limitations and follow patients for a longer period to determine the long-term cancer risk of DPP-4 inhibitors. PMID- 29573126 TI - The influence of thyroid function on the coagulation system and its clinical consequences. AB - Several studies indicate that low plasma levels of thyroid hormone shift the hemostatic system towards a hypocoagulable and hyperfibrinolytic state, whereas high levels of thyroid hormone lead to more coagulation and less fibrinolysis. Low levels of thyroid hormone thereby seem to lead to an increased bleeding risk, whereas high levels, by contrast, increase the risk of venous thromboembolism. Hypothyroidism leads to a higher incidence of acquired von Willebrand's syndrome and with increasing levels of free thyroxine, levels of fibrinogen, factor VIII and von Willebrand factor, amongst others, increase gradually, to the extent that they may lead to symptomatic venous thromboembolism in patients with hyperthyroidism. Here, we discuss the literature on the effect of thyroid hormone on the hemostatic system and the associated risk of bleeding and venous thromboembolism. Patients with hypothyroidism are at increased risk of developing bleeding complications, which could be relevant in patients undergoing invasive procedures. Furthermore, physicians should be aware of the possibility of hyperthyroidism as an underlying risk factor for venous thromboembolism, especially in unexplained cases. Clinical studies are needed to further investigate the significance for general practice of these findings. Besides the effects of hyperthyroidism on venous thromboembolism, its effects on embolism secondary to atrial fibrillation are described. PMID- 29573127 TI - Bridges of biomaterials promote nigrostriatal pathway regeneration. AB - Repair of central nervous system (CNS) lesions is difficulted by the lack of ability of central axons to regrow, and the blocking by the brain astrocytes to axonal entry. We hypothesized that by using bridges made of porous biomaterial and permissive olfactory ensheathing glia (OEG), we could provide a scaffold to permit restoration of white matter tracts. We implanted porous polycaprolactone (PCL) bridges between the substantia nigra and the striatum in rats, both with and without OEG. We compared the number of tyrosine-hydroxylase positive (TH+) fibers crossing the striatal-graft interface, and the astrocytic and microglial reaction around the grafts, between animals grafted with and without OEG. Although TH+ fibers were found inside the grafts made of PCL alone, there was a greater fiber density inside the graft and at the striatal-graft interface when OEG was cografted. Also, there was less astrocytic and microglial reaction in those animals. These results show that these PCL grafts are able to promote axonal growth along the nigrostriatal pathway, and that cografting of OEG markedly enhances axonal entry inside the grafts, growth within them, and re entry of axons into the CNS. These results may have implications in the treatment of diseases such as Parkinson's and others associated with lesions of central white matter tracts. (c) 2018 Wiley Periodicals, Inc.

AB - AIMS: To identify the strength of self-efficacy during 12-week smoking cessation therapy (SCT) that consisted of 5 sessions and its association with the success of smoking cessation at the end of SCT. BACKGROUND: Few studies showed to what level self-efficacy should be reinforced to facilitate success in smoking cessation. DESIGN: Prospective cohort study. METHODS: We enrolled 488 smokers who received SCT from 6 Japanese smoking cessation clinics between October 2008 and October 2014. In each smoker, the self-efficacy of quitting smoking was assessed at each session of SCT. The association of the strength of self-efficacy with the success of smoking cessation was investigated by logistic regression analysis adjusting for age, gender, having a present illness, prescription, and nicotine dependence score. RESULTS: The self-efficacy of the 398 abstainers was significantly higher than that of the 90 nonabstainers at the first to fifth sessions of the SCT (P < .001 each). Participants with self-efficacy scores of greater than 60% were significantly more likely to attain abstinence than those with scores of 40% and less. CONCLUSION: During SCT, nurses' counselling to maintain patients' self-efficacy scores of smoking cessation in the range from 61% to 100% may be important for assisting patients in achieving smoking cessation. PMID- 29573129 TI - Effect of periodontal ligament removal with gauze prior to delayed replantation in rabbit incisors on rate of replacement resorption. AB - BACKGROUND/AIM: Delayed (dry storage > 60 minutes) replantation results in ankylosis and replacement resorption. It has been suggested to remove the non viable periodontal ligament before replantation to possibly reduce the rate of replacement resorption. However there has been no study on the rate of replacement resorption after such measures. The aim of this study was to investigate if there was any difference in the rate of replacement resorption by either removing the periodontal ligament (PDL) with gauze or not removing PDL in teeth subjected to delayed replantation followed by healing for 2 or 6 weeks. MATERIALS AND METHODS: Maxillary central incisors were extracted in 8 rabbits. In the right central incisors, the necrotic PDL was removed by dry gauze over the root surface. In the left eight extracted teeth PDL was left on the root surface. All extracted teeth were left to dry for 60 minutes. Extra-oral root canal treatment was performed before replantation. The rabbits were sacrificed after 2 weeks and 6 weeks respectively. Histologic processing and evaluation was done. RESULTS: In the 2 weeks group, all teeth showed ankylosis. The cementum was intact, and fusion of the bone and root was generally seen without resorption of the root, whereas in the 6 weeks group regardless of whether PDL had been kept or not, ankylosis and osseous replacement of the dentin was seen. There was no evidence of inflammatory infiltrate in the sections examined. CONCLUSION: Removal of PDL prior to delayed replantation may result in some initial protection of the cementum during the first few weeks. However, over longer times there seems to be neither protection of the dentin from ankylosis and osseous replacement, nor any influence on the rate of replacement resorption. PMID- 29573130 TI - Biomimetic design of bone substitutes based on cuttlefish bone-derived hydroxyapatite and biodegradable polymers. AB - Being a major component of bone tissue, hydroxyapatite is the most investigated calcium phosphate in the design and development of bone implants. The high brittleness and poor load-bearing properties have led researchers to manipulate hydroxyapatite performance by applying polymer or metal materials. The present study focuses on biomimetic approach of the hydroxyapatite synthesis from the cuttlefish bone in order to preserve highly porous structure. The low stiffness of hydroxyapatite scaffold was altered by thin polycaprolactone/poly(lactic acid) coating, resulting in remarkably 18-fold increase of Young's modulus. The mechanical test revealed that poly(lactic acid) increases the stiffness of composite scaffolds which depends on the polycaprolactone/poly(lactic acid) volume ratio. The composite scaffolds are bioactive supporting the deposition of new calcium phosphates when incubated in simulated physiological medium for 21 days. Moreover, the culture of human embryonic kidney cells indicated non cytotoxicity of the composite scaffolds with emphasis on the cell proliferation during three days of culture.

PMID- 29573131 TI - Achieving Sustained Virological Response in Liver Transplant Recipients With Hepatitis C Decreases Risk of Decline in Renal Function. AB - The effect of antiviral therapy (AVT) on kidney function in liver transplantation (LT) recipients has not been well described despite known association of hepatitis C virus (HCV) infection with chronic kidney disease (CKD). We compared the incidence of CKD and end-stage renal disease (ESRD) in 204 LT recipients with HCV based on treatment response to AVT. The mean estimated glomerular filtration rate (eGFR) at baseline (3 months after LT) was similar in the sustained virological response (SVR; n = 145) and non-SVR group (n = 59; 69 +/- 21 versus 65 +/- 33 mL/minute/1.73 m2 ; P = 0.27). In the unadjusted Cox proportional regression analysis, the presence of SVR was associated with an 88% lower risk of CKD (hazard ratio, 0.12; 95% confidence interval [CI], 0.05-0.31) and 86% lower risk of ESRD (odds ratio, 0.14; 95% CI, 0.05-0.35). Similar results were found after adjusting for propensity score and time-dependent Cox regression analyses. The estimated slopes of eGFR based on a 2-stage mixed model of eGFR were calculated. Patients with SVR had a less steep slope in eGFR (-0.60 mL/minute/1.73 m2 /year; 95% CI, -1.50 to 0.30; P = 0.190) than recipients without SVR (-2.53 mL/minute/1.73 m2 /year; 95% CI, -3.99 to -1.07; P = 0.001), and the differences in the slopes were statistically significant (P = 0.026). In conclusion, in LT recipients with chronic HCV infection, achieving SVR significantly lowers the risk of decline in renal function and progression to ESRD independent of the AVT therapy used. PMID- 29573132 TI - Effects of different etching modes on the nanoleakage of universal adhesives: A systematic review and meta-analysis. AB - PURPOSE: The aim of this systematic review was to evaluate how etching modes affect the nanoleakage of universal adhesive from in vitro studies. MATERIALS AND METHODS: PubMed/MEDLINE, Web of Science, Scopus and Science Direct electronic databases were searched for in vitro studies that evaluated the nanoleakage of universal adhesives. A total of 511 (after duplicate removal) potentially relevant records were identified in the literature search. The titles and abstracts of the retrieved studies were screened by two independent researchers according to the main concept. Subsequently, the full text of potentially relevant studies was screened using the exclusion criteria. Thirteen studies were subjected to qualitative analysis, and 5 of them were selected for a detailed meta-analysis. RESULTS: Seven universal adhesives were evaluated in this review. The meta-analysis demonstrated that the etch-and-rinse technique significantly reduced the nanoleakage of the Peak Universal and G-Bond Plus adhesives, whereas the self-etch mode reduced the nanoleakage of All-Bond Universal. In comparison, the etching technique did not significantly alter the nanoleakage of either Prime&Bond Elect or Scotchbond Universal which was characterized by the smallest nanoleakage. CONCLUSIONS: Etching modes significantly, in various ways, influence the nanoleakage of universal adhesives. CLINICAL SIGNIFICANCE: Contrary to the drive to simplify bonding technologies, an appreciation of their adhesive components and how these perform according to bonding technique could yield a knowledge-based practical approach that ultimately improves the longevity of direct composite restorations. PMID- 29573134 TI - Magnetoelastic galfenol as a stent material for wirelessly controlled degradation rates. AB - The gold standard of care for coronary artery disease, a leading cause of death for in the world, is balloon angioplasty in conjunction with stent deployment. However, implantation injuries and long-term presence of foreign material often promotes significant luminal tissue growth, leading to a narrowing of the artery and severely restricted blood flow. A promising method to mitigate this process is the use of biodegradable metallic stents, but thus far they have either degraded too slowly (iron) or disappeared prematurely (magnesium). The present work investigates the use of a unique type of magnetic material, galfenol (iron gallium), for postoperative wireless control of stent degradation rates. Due to its magnetoelastic property, galfenol experiences longitudinal micron-level elongations when exposed to applied magnetic fields, allowing generation of a microstirring effect that affect its degradation behavior. In vitro indirect cytotoxicity tests on primary rat aortic smooth muscle cells indicated that galfenol byproducts must be concentrated approximately seven times from collected 60 day degradation medium to cause ~15% of death from all cells. Surface and cross-sectional characterization of the material indicate that galfenol (Fe80 Ga20 ) degradation rates (~0.55% per month) are insufficient for stenting applications. While this material may not be ideal for comprising the entire stent, there is potential for use in combination with other materials. Furthermore, the ability to control degradation rates postimplantation opens new possibilities for biodegradable stents; additional magnetoelastic materials should be investigated for use in stenting applications.

AB - Specific intracellular localization of RAB GTPases has been reported to be dependent on protein factors, but the contribution of the membrane physicochemical properties to this process has been poorly described. Here, we show that three RAB proteins (RAB1/RAB5/RAB6) preferentially bind in vitro to disordered and curved membranes, and that this feature is uniquely dependent on their prenyl group. Our results imply that the addition of a prenyl group confers to RAB proteins, and most probably also to other prenylated proteins, the ability to sense lipid packing defects induced by unsaturated conical-shaped lipids and curvature. Consistently, RAB recruitment increases with the amount of lipid packing defects, further indicating that these defects drive RAB membrane targeting. Membrane binding of RAB35 is also modulated by lipid packing defects but primarily dependent on negatively charged lipids. Our results suggest that a balance between hydrophobic insertion of the prenyl group into lipid packing defects and electrostatic interactions of the RAB C-terminal region with charged membranes tunes the specific intracellular localization of RAB proteins.

AB - BACKGROUND: The mite Brevipalpus yothersi (Acari: Tenuipalpidae) is of great importance in citriculture because it is a vector of the disease citrus leprosis. The frequency of application of a combination of pesticides has increased because of an increase in the occurrence of economically important pests of citrus. However, the combined effect of acaricide and other insecticides targeting B. yothersi is unknown. The objective of this study was to evaluate the effect of a combination of spirodiclofen and other insecticides on the control of B. yothersi. RESULTS: Analysis using spirodiclofen alone resulted in 97.22% efficiency in the control of B. yothersi on day 7 after application. A combination of spirodiclofen with either phosmet or imidacloprid resulted in 55% and 59% efficiency, respectively. A reduction in the efficiency of mite control by up to 42% was observed when the mites were exposed to a combination of acaricide with other insecticides. CONCLUSIONS: Application of a combination of spirodiclofen with phosmet or imidacloprid compromises the efficiency of acaricide in the control of B. yothersi. (c) 2018 Society of Chemical Industry.

AB - For lead compound discovery from natural products, hollow fiber cell fishing with chromatographic analysis is a newly developed method. In this study, an adsorbed hollow fiber-based biological fingerprinting method was firstly developed to discover potential platelet aggregation inhibitors from Danshen-Honghua decoction. Platelets were seeded on the fiber and their survival rate was tested. Results indicated that more than 92% platelets survived during the whole operation process. Ranitidine and tirofiban were used as positive and negative control respectively to verify the reliability of the presented approach. The main variables such as amount of extract and stirring time that affect the adsorbed hollow fiber-based biological fingerprinting process were optimized, and the repeatability of this method was also investigated. Finally, 12 potential active compounds in Danshen-Honghua decoction were successfully detected using the established approach and structures for nine of them were tentatively identified by liquid chromatography with mass spectrometry analysis. In addition, the in vitro platelet aggregation inhibition test was carried out for five of the nine hit compounds, and three active components, namely, lithospermic acid, salvianolic acid A, and salvianolic acid B were confirmed. These results proved that the proposed method could be an effective approach for screening platelet inhibitors from plant extracts. PMID- 29573137 TI - Heterozygosity for the alpha-1-antitrypsin Z allele in cirrhosis is associated with more advanced disease. AB - Alpha-1-antitrypsin deficiency (A1ATD) due to homozygosity for the Z allele (ZZ) is an established risk factor for cirrhosis, but the liver disease risk in heterozygous Z allele carriers (MZ) is controversial. The aim of the present study was to determine the prevalence of the MZ genotype among patients with cirrhosis and the associated risk of decompensation and liver transplantation/mortality. An unselected cohort of 561 patients with cirrhosis and 248 deceased liver donors were genotyped for the A1ATD risk alleles Z and S using a validated allelic discrimination assay. Clinical and biochemical parameters were assessed in 488 genotype MM and 52 MZ patients at baseline when cirrhosis was diagnosed and at the last contact, before liver transplantation or death, as study endpoints. MZ prevalence was 2.8% among liver donors, 5.8%, 9.1%, 10.9%, and 19.0% in patients with cirrhosis and Model for End-Stage Liver Disease sodium (MELD-Na) <=10, 11-20, 21-30, and >30, respectively. Among liver transplant recipients, MZ prevalence was 9.7%. MS prevalence was not different between donors, patients with cirrhosis, or transplant recipients. At the end of follow-up, MELD-Na scores were higher among heterozygous Z risk allele carriers (16 versus 19; P = 0.03). Decompensation of cirrhosis with ascites or encephalopathy was significantly more frequent in patients with MZ than in MM patients. In the subgroup with transferrin (Tf) saturation >50% or Tf <180 mg/dL, MZ patients had a significantly higher risk of liver transplantation or death than MM patients. In conclusion, the genotype MZ is a genetic risk factor for more advanced cirrhosis and decompensation. MZ patients with cirrhosis and hypotransferrinemia or increased Tf saturation are at higher risk of death and liver transplantation. Liver Transplantation 24 744-751 2018 AASLD. PMID- 29573138 TI - High Electromagnetic Field Enhancement of TiO2 Nanotube Electrodes. AB - We present the fabrication of TiO2 nanotube electrodes with high biocompatibility and extraordinary spectroscopic properties. Intense surface-enhanced resonance Raman signals of the heme unit of the redox enzyme Cytochrome b5 were observed upon covalent immobilization of the protein matrix on the TiO2 surface, revealing overall preserved structural integrity and redox behavior. The enhancement factor could be rationally controlled by varying the electrode annealing temperature, reaching a record maximum value of over 70 at 475 degrees C. For the first time, such high values are reported for non-directly surface-interacting probes, for which the involvement of charge-transfer processes in signal amplification can be excluded. The origin of the surface enhancement is exclusively attributed to enhanced localized electric fields resulting from the specific optical properties of the nanotubular geometry of the electrode.

AB - This analysis assessed whether responses with exenatide once weekly plus dapagliflozin (n = 231), exenatide once weekly alone (n = 230), or dapagliflozin alone (n = 233) differed in key patient subpopulations of the DURATION-8 trial. Potential treatment-by-subgroup interactions for changes in glycated haemoglobin (HbA1c) and body weight after 28 weeks were evaluated among subgroups determined by baseline HbA1c, age, sex, body mass index, type 2 diabetes duration, race, ethnicity and estimated glomerular filtration rate (eGFR). Exenatide once weekly plus dapagliflozin reduced HbA1c and body weight across all subgroups: least squares mean reductions ranged from -8.4 to -26.1 mmol/mol (-0.77% to -2.39%) for HbA1c and from -2.07 to -4.55 kg for body weight. Potential treatment-by-subgroup interactions (P < .10) were found for HbA1c change by age (P = .016) and eGFR (P = .097). Age subgroup analysis findings were not consistent with expected mechanistic effects, with the small number of patients aged >=65 years (n = 74 vs n = 499 for patients aged <65 years) limiting the interpretability of the interaction term. In the exenatide once weekly plus dapagliflozin and dapagliflozin groups, but not the exenatide once weekly group, HbA1c reductions were greater among patients with eGFR >=90 vs >=60 to <90 mL/min/1.73 m2 (least squares mean reductions of -23.6 vs -19.0 mmol/mol [-2.16% vs -1.74%], -17.3 vs 12.0 mmol/mol [-1.58% vs -1.10%], and -17.7 vs -16.9 mmol/mol [-1.62% vs -1.55%] for the respective treatments); this was consistent with the mechanism of action of dapagliflozin. A potential treatment-by-subgroup interaction was observed for change in body weight by sex (P = .099), with greater weight loss for women vs men across all treatments (range -2.56 to -3.98 kg vs -0.56 to -2.99 kg). In conclusion, treatment with exenatide once weekly plus dapagliflozin reduced HbA1c and body weight across all patient subgroups and was more effective than exenatide once weekly or dapagliflozin alone in all adequately sized subgroups. PMID- 29573140 TI - Quantitative analysis of image quality for acceptance and commissioning of an MRI simulator with a semiautomatic method. AB - Magnetic Resonance Imaging (MRI) simulation differs from diagnostic MRI in purpose, technical requirements, and implementation. We propose a semiautomatic method for image acceptance and commissioning for the scanner, the radiofrequency (RF) coils, and pulse sequences for an MRI simulator. The ACR MRI accreditation large phantom was used for image quality analysis with seven parameters. Standard ACR sequences with a split head coil were adopted to examine the scanner's basic performance. The performance of simulation RF coils were measured and compared using the standard sequence with different clinical diagnostic coils. We used simulation sequences with simulation coils to test the quality of image and advanced performance of the scanner. Codes and procedures were developed for semiautomatic image quality analysis. When using standard ACR sequences with a split head coil, image quality passed all ACR recommended criteria. The image intensity uniformity with a simulation RF coil decreased about 34% compared with the eight-channel diagnostic head coil, while the other six image quality parameters were acceptable. Those two image quality parameters could be improved to more than 85% by built-in intensity calibration methods. In the simulation sequences test, the contrast resolution was sensitive to the FOV and matrix settings. The geometric distortion of simulation sequences such as T1-weighted and T2-weighted images was well-controlled in the isocenter and 10 cm off-center within a range of +/-1% (2 mm). We developed a semiautomatic image quality analysis method for quantitative evaluation of images and commissioning of an MRI simulator. The baseline performances of simulation RF coils and pulse sequences have been established for routine QA. PMID- 29573141 TI - A multicenter investigation of respiratory syncytial viral infection in children with hematopoietic cell transplantation. AB - BACKGROUND: Hematopoietic cell transplant (HCT) may be a risk factor for morbidity and mortality from respiratory syncytial virus (RSV). Previous studies have been limited by small sample size. We took a multicenter approach with the goal of better understanding the epidemiology, risk factors, treatment, morbidity, and mortality associated with RSV infections among children with HCT in the United States. METHODS: A retrospective, multicenter, cohort study of pediatric HCT recipients were diagnosed with RSV infection between January 2010 and December 2014. RESULTS: Of the 1522 HCT, 47 (3%) patients were diagnosed with RSV. Of those with RSV, 9 (19.1%) were admitted to the pediatric intensive care unit (PICU), 6 (12.8%) received invasive mechanical ventilation, and 1 died. Prophylactic palivizumab was uncommon. All who required critical care received ribavirin vs 7.3% of those who did not (P = .004). Cobacterial infections were found in 16 patients and were not associated with the need for critical care. We examined potential risk factors for severity of RSV disease. In those who received invasive ventilation, 100% had one of the preidentified risk factors. Half of those requiring mechanical ventilation were diagnosed with RSV during their conditioning for transplant as opposed to only 2.4% of those that did not require invasive mechanical ventilation (P = .005). CONCLUSIONS: In this multicenter cohort, RSV was not common in children following HCT. Few children infected with RSV required critical care and mortality was low. Those diagnosed with RSV during conditioning for transplant were at higher risk for invasive mechanical ventilation. PMID- 29573142 TI - Development of an unbiased, semi-automated approach for classifying plasma cell immunophenotype following multicolor flow cytometry of bone marrow aspirates. AB - BACKGROUND: Despite increased usage of multiparameter flow cytometry (MFC) to assess diagnosis, prognosis, and therapeutic efficacy (minimal residual disease, MRD) in plasma cell neoplasms (PCNs), standardization of methodology and data analysis is suboptimal. We investigated the utility of using the mean and median fluorescence intensities (FI) obtained from MFC to objectively describe parameters that distinguish plasma cell (PC) phenotypes. METHODS: In this retrospective study, flow cytometry results from bone marrow aspirate specimens from 570 patients referred to the Myeloma Institute at UAMS were evaluated. Mean and median FI data were obtained from 8-color MFC of non-neoplastic, malignant, and mixed PC populations using antibodies to CD38, CD138, CD19, CD20, CD27, CD45, CD56, and CD81. RESULTS: Of 570 cases, 252 cases showed only non-neoplastic PCs, 168 showed only malignant PCs, and 150 showed mixed PC populations. Statistical analysis of median FI data for each CD marker showed no difference in expression intensity on non-neoplastic and malignant PCs, between pure and mixed PC populations. ROC analysis of the median FI of CD expression in non-neoplastic and malignant PCs was used to develop an algorithm to convert quantitative FI values to qualitative assessments including "negative," "positive," "dim," and "heterogeneous" expression. CONCLUSIONS: FI data derived from 8-color MFC can be used to define marker expression on PCs. Translation of FI data from Infinicyt software to an Excel worksheet streamlines workflow and eliminates transcriptional errors when generating flow reports.

PMID- 29573143 TI - The safety and efficacy of quadrivalent live attenuated influenza vaccine in Japanese children aged 2-18 years: Results of two phase 3 studies. AB - BACKGROUND: Quadrivalent live attenuated influenza vaccine (Q/LAIV) has not been assessed in Japanese children. OBJECTIVES: Evaluate safety and efficacy of Q/LAIV in Japanese children. PATIENTS/METHODS: Two phase 3 studies were conducted in the 2014-2015 influenza season. Study 1 was an open-label, uncontrolled single arm, multicenter study of Q/LAIV safety in subjects aged 2-6 years. Study 2 was a randomized, double-blind, placebo-controlled multicenter study of Q/LAIV safety and efficacy; subjects aged 7-18 years were randomized 2:1 to receive Q/LAIV or placebo. Primary efficacy endpoint was laboratory-confirmed symptomatic influenza infection caused by vaccine-matched strains; secondary endpoint evaluated efficacy against all strains regardless of match. Both studies reported solicited symptoms, adverse events (AEs), and serious AEs. RESULTS: In Study 1, 100 subjects received Q/LAIV. In Study 2, 1301 subjects received Q/LAIV (n = 868) or placebo (n = 433). Treatment-emergent AEs occurred in 42% of subjects in Study 1, and in 24.3% of subjects in the Q/LAIV arm and in 25.9% of subjects in the placebo arm in Study 2. In Study 2, a single infection by a vaccine-matched strain was reported in the placebo arm, resulting in a vaccine efficacy estimate of 100% (95% CI: -1875.3, 100.0); efficacy for all strains regardless of match to the vaccine was 27.5% (95% CI: 7.4, 43.0). CONCLUSIONS: Quadrivalent live attenuated influenza vaccine did not meet its primary efficacy endpoint as only a single infection by a vaccine-matched strain was detected; however, efficacy for the secondary endpoint, all strains regardless of match, was achieved. Q/LAIV was generally well tolerated in the Japanese pediatric population. PMID- 29573144 TI - Relevance of the Thought-Shape Fusion Trait Questionnaire for healthy women and women presenting symptoms of eating disorders and mixed mental disorders. AB - Thought-shape fusion (TSF) describes the experience of marked concerns about body weight/shape, feelings of fatness, the perception of weight gain, and the impression of moral wrongdoing after thinking about eating fattening/forbidden foods. This study sets out to evaluate the short version of the TSF trait questionnaire (TSF). The sample consists of 315 healthy control women, 244 women with clinical and subthreshold eating disorders, and 113 women with mixed mental disorders (mixed). The factor structure of the TSF questionnaire was examined using exploratory and subsequent confirmatory factor analyses. The questionnaire distinguishes between a Concept scale and a Clinical Impact scale. However, a lack of measurement invariances refers to significant differences between groups in terms of factor loadings, thresholds, and residuals, which questions cross group validity. Results indicate that the concept is understood differently in the 3 groups and refers to the suitability of the questionnaire primarily for individuals presenting with symptoms of eating disorders. PMID- 29573146 TI - Self-care in Preserving the Vascular Network: Old Problem, New Challenge for the Medical Staff. AB - Teaching/educating patients with end stage renal disease (ESRD) and identifying their self-care behaviors for vascular network preservation are very important. However, the self-care behaviors regularly performed by patients are still unknown. We compared self-care behaviors for vascular network preservation performed by patients who are/are not followed-up by the nephrologist. The study design was a prospective, observational and comparative study. Inclusion criteria were as follows: ESRD patients (at stages 4 or 5); at least 18 years old; in pre dialysis with at least a 6-month follow-up period by the nephrologist or who started dialysis in emergency and were not followed-up by the nephrologist; with no memory problems; and medically stable. Primary outcome was the frequency of self-care behaviors for vascular network preservation. Secondary outcome was the comparison between self-care behaviors by ESRD patients who were/were not followed-up by the nephrologist. The study involved 145 patients, 64.1% were female, the mean age was 69.5 years and the self-care behaviors mean score was 36.8% (with a SD of 39.8%). The number of patients followed-up and not followed up by the nephrologist was 109 (group 1) and 36 (group 2), respectively. Social characteristics were similar in the two groups (P > 0.05). The mean self-care behaviors were 29.4% and 59.2% in groups 1 and 2, respectively (P = 0.000). Patients performed self-care behaviors for vascular network preservation with a relatively low frequency (the mean score was 36.8% only). Patients not followed by the nephrologist performed self-care behaviors more often than those who were followed (59.2% vs. 29.4% respectively, P = 0.000). PMID- 29573145 TI - Profiling of m6A RNA modifications identified an age-associated regulation of AGO2 mRNA stability. AB - Gene expression is dynamically regulated in a variety of mammalian physiologies. During mammalian aging, there are changes that occur in protein expression that are highly controlled by the regulatory steps in transcription, post transcription, and post-translation. Although there are global profiles of human transcripts during the aging processes available, the mechanism(s) by which transcripts are differentially expressed between young and old cohorts remains unclear. Here, we report on N6-methyladenosine (m6A) RNA modification profiles of human peripheral blood mononuclear cells (PBMCs) from young and old cohorts. An m6A RNA profile identified a decrease in overall RNA methylation during the aging process as well as the predominant modification on proteincoding mRNAs. The m6A modified transcripts tend to be more highly expressed than nonmodified ones. Among the many methylated mRNAs, those of DROSHA and AGO2 were heavily methylated in young PBMCs which coincided with a decreased steady-state level of AGO2 mRNA in the old PBMC cohort. Similarly, downregulation of AGO2 in proliferating human diploid fibroblasts (HDFs) also correlated with a decrease in AGO2 mRNA modifications and steady-state levels. In addition, the overexpression of RNA methyltransferases stabilized AGO2 mRNA but not DROSHA and DICER1 mRNA in HDFs. Moreover, the abundance of miRNAs also changed in the young and old PBMCs which are possibly due to a correlation with AGO2 expression as observed in AGO2 depleted HDFs. Taken together, we uncovered the role of mRNA methylation on the abundance of AGO2 mRNA resulting in the repression of miRNA expression during the process of human aging. PMID- 29573147 TI - Anxiolytic effect of anacardic acids from cashew (Anacardium occidentale) nut shell in mice. AB - Antianxiety drugs currently in use are associated with a number of serious side effects. Present study was designed to evaluate the efficacy of anacardic acids (AAs) isolated from cashew nut (Anacardium occidentale L.) shell liquid (CNSL) to treat anxiety as well as its role in oxidative stress in mice model. Anxiolytic effect of AA was evaluated using rota-rod and a set of behavioral tests in male Swiss albino mice at the doses of 10, 25, and 50 mg/kg. Flumazenil was used to evaluate the possible involvement of GABAergic system in the mechanism of action of AA. The effect of AA on oxidative stress in mice was evaluated by determining the concentration of malondialdehyde (MDA), reduced glutathione, and catalase (CAT) activity. The detection of DNA damage of the treated animals was performed using alkaline comet test in the hippocampus and frontal cortex of the animals. The results demonstrated that AA did not produce myorelaxant and sedative effects, nor did it cause a decrease in locomotor activity. The anxiolytic effect of AA was well-evident in all tests, especially at higher dose levels (25 and 50 mg/mg). Flumazenil reversed the anxiolytic effect of AA at all doses. In addition, AA reduced oxidative stress by decreasing the concentration of MDA and increasing the levels of reduced glutathione (GSH) and CAT activity. Statistical analysis by Pearson's correlation indicated a positive correlation between anxiolytic effect of AA to its antioxidant and lipid peroxidation inhibitory activity. Furthermore, increased CAT activity and GSH concentrations in the hippocampus and frontal cortex of mice was also complementary to the reduced genotoxic damage observed in the study. In comet assay, AA did not increase in DNA damage. In conclusion, the results supported that AA possesses GABAA receptor mediated anxiolytic activity with the lack of myorelaxation and genotoxicity.

AB - Activity-guided fractionation strategy was used to investigate chemical constituents from the roots of Podocarpus macrophyllus. Successfully, two new norditerpenes, 2beta-hydroxymakilactone A (1) and 3beta-hydroxymakilactone A (2), along with ten known analogues (3 - 12) were isolated. The structures of 1 and 2 were elucidated by spectroscopic analysis including 1D-, 2D-NMR, and HR-ESI-MS data. The previously reported structure of 2,3-dihydro-2alpha-hydroxypodolide was revised as 2,3-dihydro-2beta-hydroxypodolide (3) by spectroscopic analysis, and was further confirmed by X-ray crystallographic analysis. Cytotoxic activities of all isolated compounds against five human solid tumour cell lines (AGS, HeLa, MDA MB-231, HepG-2, and PANC-1) were evaluated. All of them exhibited anti proliferative activities (IC50 = 0.3 - 27 MUm), except for 10. Compounds 1, 4, 5, 6, and 8 exhibited potent inhibitory activities with IC50 < 1 MUm against HeLa and AGS cells. PMID- 29573149 TI - Freeze-thaw approach: A practical sample preparation strategy for residue analysis of multi-class veterinary drugs in chicken muscle. AB - Seven drugs from different classes, namely, fluoroquinolones (enrofloxacin, ciprofloxacin, sarafloxacin), sulfonamides (sulfadimidine, sulfamonomethoxine), and macrolides (tilmicosin, tylosin), were used as test compounds in chickens by oral administration, a simple extraction step after cryogenic freezing might allow the effective extraction of multi-class veterinary drug residues from minced chicken muscles by mix vortexing. On basis of the optimized freeze-thaw approach, a convenient, selective, and reproducible liquid chromatography with tandem mass spectrometry method was developed. At three spiking levels in blank chicken and medicated chicken muscles, average recoveries of the analytes were in the range of 71-106 and 63-119%, respectively. All the relative standard deviations were <20%. The limits of quantification of analytes were 0.2-5.0 ng/g. Regardless of the chicken levels, there were no significant differences (P > 0.05) in the average contents of almost any of the analytes in medicated chickens between this method and specific methods in the literature for the determination of specific analytes. Finally, the developed method was successfully extended to the monitoring of residues of 55 common veterinary drugs in food animal muscles. PMID- 29573150 TI - Determination of oxalate and citrate in urine by capillary electrophoresis using solid-phase extraction and capacitively coupled contactless conductivity based on an improved mini-cell. AB - A new method for the rapid determination of the metabolites oxalate and citrate in urine samples was based on capillary electrophoresis and capacitively coupled contactless conductivity detection coupled with solid-phase extraction. The detection cell for capacitively coupled contactless conductivity detection was improved with a smaller inner volume (1.5 nL), reduced noise (0.2~0.5 mV) and better reproducibility and durability. Under optimal conditions, oxalate and citrate can achieve baseline separation within 4 min and the detection limits (S/N = 3) for oxalate and citrate are about 44 and 244 ng/mL, respectively. The overall recovery is between 80.0 and 89.2%. This method offers a better choice for quantitative analysis of strong anions such as oxalate and citrate in diagnostic testing associated with human diseases. PMID- 29573152 TI - The benefits of being a near-peer teacher. AB - BACKGROUND: Near-peer teaching is used in anatomy education because of its benefits to the learner, teacher and faculty members. Despite the range of reports focusing on the learner, the advantages for the teacher, which are thought to include communication skills, subject knowledge and employability, are only beginning to be explored. METHOD: A questionnaire was distributed to the teachers involved in anatomy near-peer teaching at the University of Southampton and Brighton and Sussex Medical School (BSMS). This questionnaire was designed using a rating scale of 0-10 to assess teacher perspectives on their level of knowledge, teaching skills and enjoyment of teaching. Free-text responses determined the teachers' motivation and perceived benefits from the teaching. RESULTS: Twenty-eight questionnaires were gathered (54.9% response rate), including 20 from Southampton and eight from BSMS. Long-term knowledge retention and better understanding of the material were rated 8.1 and 7.9 out of 10, respectively. Eight responses were from currently practising doctors, who rated how much they now use their teaching skills as doctors as 8.9 out of 10. Of the eight doctors, seven gained points for their foundation programme applications as a direct result of near-peer teaching. The most common motivator for engaging in teaching was to improve subject matter knowledge and the most common benefit was improved communication skills. There are numerous advantages to being a near-peer teacher in medical school DISCUSSION: There are numerous advantages to being a near-peer teacher in medical school, which include knowledge improvement, transferrable professional skills and employability. These initial results support the hypothesised benefits to the teachers and provide a foundation for further longitudinal studies. PMID- 29573153 TI - Cognitive learning theory for clinical teaching. PMID- 29573151 TI - More than just sugars: Conserved oligomeric Golgi complex deficiency causes glycosylation-independent cellular defects. AB - The conserved oligomeric Golgi (COG) complex controls membrane trafficking and ensures Golgi homeostasis by orchestrating retrograde vesicle trafficking within the Golgi. Human COG defects lead to severe multisystemic diseases known as COG congenital disorders of glycosylation (COG-CDG). To gain better understanding of COG-CDGs, we compared COG knockout cells with cells deficient to 2 key enzymes, Alpha-1,3-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase and uridine diphosphate-glucose 4-epimerase (GALE), which contribute to proper N- and O-glycosylation. While all knockout cells share similar defects in glycosylation, these defects only account for a small fraction of observed COG knockout phenotypes. Glycosylation deficiencies were not associated with the fragmented Golgi, abnormal endolysosomes, defective sorting and secretion or delayed retrograde trafficking, indicating that these phenotypes are probably not due to hypoglycosylation, but to other specific interactions or roles of the COG complex. Importantly, these COG deficiency specific phenotypes were also apparent in COG7-CDG patient fibroblasts, proving the human disease relevance of our CRISPR knockout findings. The knowledge gained from this study has important implications, both for understanding the physiological role of COG complex in Golgi homeostasis in eukaryotic cells, and for better understanding human diseases associated with COG/Golgi impairment. PMID- 29573155 TI - Determining discharge destination in geriatric evaluation and management units: Is progressive goal attainment a better early indicator of discharge destination than improvement in functional independence measure scores? AB - AIM: To determine whether progress in goal attainment is a more responsive measure of functional improvement than the Functional Independence Measure, and whether it is a more accurate predictor of discharge destination in the early phase of a Geriatric Evaluation and Management episode. METHODS: The present study was a prospective audit of goal achievement, functional ability and discharge destination. A total of 83 patients were included in this study. Logistic regression was carried out with the outcome variable discharge destination (home vs residential care), and the predictors being goal attainment, age at admission and change in the Functional Independence Measure motor function scale from admission to 2 weeks. RESULTS: Of the predictors, goal attainment was the only significant predictor. The overall amount of variability in the discharge destination explained by the predictors was 25% (Nagelkerke pseudo R2 ). CONCLUSIONS: Progressive goal attainment might be a better predictor of improvement in function and discharge destination than change in the Functional Independence Measure.

AB - SCOPE: 3-Methylhistidine (3-MH) as a potential biomarker for muscle protein turnover is influenced by meat intake but data on the impact of meat on plasma 3 MH are scarce. We determined the association of plasma 3-MH, 1-methylhistidine (1 MH), and creatinine with dietary habits and assessed the impact of a single white meat intervention during a meat-free period. METHODS AND RESULTS: Plasma 3-MH, 1 MH, and creatinine concentrations of healthy young omnivores (n = 19) and vegetarians (n = 16) were analyzed together with data on anthropometry, body composition, grip strength, and nutrition. After baseline measurements omnivores adhered to a meat-free diet for 6 days and received a defined administration of chicken breast on day four. At baseline, omnivores had higher plasma 3-MH and 1 MH concentrations than vegetarians. White meat administration led to a slight increase in plasma 3-MH in omnivores. The elevated 3-MH concentrations significantly declined within 24 h after white meat intake. CONCLUSION: 1-MH concentrations in plasma seem to be suitable to display (white) meat consumption and its influence on 3-MH plasma concentration. 3-MH in plasma may be used as a biomarker for muscle protein turnover if subjects have not consumed meat in the previous 24 h.

PMID- 29573157 TI - Dynamics of influenza in tropical Africa: Temperature, humidity, and co circulating (sub)types. AB - BACKGROUND: The association of influenza with meteorological variables in tropical climates remains controversial. Here, we investigate the impact of weather conditions on influenza in the tropics and factors that may contribute to this uncertainty. METHODS: We computed the monthly viral positive rate for each of the 3 circulating influenza (sub)types (ie, A/H1N1, A/H3N2, and B) among patients presenting with influenza-like illness (ILI) or severe acute respiratory infections (SARI) in 2 Ugandan cities (Entebbe and Kampala). Using this measure as a proxy for influenza activity, we applied regression models to examine the impact of temperature, relative humidity, absolute humidity, and precipitation, as well as interactions among the 3 influenza viruses on the epidemic dynamics of each influenza (sub)type. A full analysis including all 4 weather variables was done for Entebbe during 2007-2015, and a partial analysis including only temperature and precipitation was done for both cities during 2008-2014. RESULTS: For Entebbe, the associations with weather variables differed by influenza (sub)type; with adjustment for viral interactions, the models showed that precipitation and temperature were negatively correlated with A/H1N1 activity, but not for A/H3N2 or B. A mutually negative association between A/H3N2 and B activity was identified in both Entebbe and Kampala. CONCLUSION: Our findings suggest that key interactions exist among influenza (sub)types at the population level in the tropics and that such interactions can modify the association of influenza activity with weather variables. Studies of the relationship between influenza and weather conditions should therefore determine and account for co circulating influenza (sub)types. PMID- 29573158 TI - Chemotherapy in patients with unresected pancreatic cancer in Australia: A population-based study of uptake and survival. AB - AIM: Palliative chemotherapy improves symptom control and prolongs survival in patients with unresectable pancreatic cancer, but there is a paucity of data describing its use and effectiveness in everyday practice. We explored patterns of chemotherapy use in patients with unresected pancreatic cancer in Australia and the impact of use on survival. METHODS: We reviewed the medical records of residents of New South Wales or Queensland, Australia, diagnosed with unresectable pancreatic adenocarcinoma between July 2009 and June 2011. Associations between receipt of chemotherapy and sociodemographic, clinical and health service factors were evaluated using logistic regression. We used Cox proportional hazards models to analyze associations between chemotherapy use and survival. RESULTS: Data were collected for 1173 eligible patients. Chemotherapy was received by 44% (n = 184/414) of patients with localized pancreatic cancer and 53% (n = 406/759) of patients with metastases. Chemotherapy receipt depended on clinical factors, such as performance status and comorbidity burden, and nonclinical factors, such as age, place of residence, multidisciplinary team review and the type of specialist first encountered. Consultation with an oncologist mitigated most of the sociodemographic and service-related disparities in chemotherapy use. The receipt of chemotherapy was associated with prolonged survival in patients with inoperable pancreatic cancer, including after adjusting for common prognostic factors. CONCLUSIONS: These findings highlight the need to establish referral pathways to ensure that all patients have the opportunity to discuss treatment options with a medical oncologist. This is particularly relevant for health care systems covering areas with a geographically dispersed population. PMID- 29573159 TI - Patients' experiences and preferences for opt-in models and health professional involvement in biobanking consent: A cross-sectional survey of Australian cancer outpatients. AB - BACKGROUND: Many biobanks rely upon patients' willingness to donate biospecimens and healthcare professionals to initiate opt-in consent processes. This study explored if: (1) patients accept opt-in or opt-out consent models with varying levels of professional involvement; (2) professionals discuss participation with specific patient groups; and (3) this discussion is associated with patient knowledge of biobanking processes. METHODS: Outpatients completed surveys at a tertiary cancer center in New South Wales, Australia. Eligible participants were English-speaking adults who recently had cancer-related surgery. Participants completed 27 questions exploring acceptable consent models, biobanking experiences, knowledge, and willingness. Logistic regression and chi-square tests examined differences in the characteristics and knowledge of participants who were offered the opportunity to participate versus those who were not. RESULTS: A total of 113 outpatients participated (97% response). Most participants (92%) found opt-out, patient-initiated consent acceptable; however, high acceptability was reported for all models except for opt-in, patient-initiated consent (58%). University or technical qualifications (P = 0.001) was associated with increased odds (OR = 4.5) of being offered biobanking. The majority did not know what occurred to samples after surgery (59.3%) or pathology review (81.4%) and ability to answer these questions was associated with discussion of participation (P < 0.001). Of the few outpatients who discussed biobanking with their doctor (29%), all consented. CONCLUSION: Professional-initiated, opt-in consent resulted in a few educated patients being approached; greater professional initiation of consent would be fruitful as most patients were willing to participate if asked. However, other consent approaches minimizing professional involvement were as acceptable to participants warranting further consideration. PMID- 29573160 TI - Intraseasonal asynchrony as a factor boosting isolation within a metapopulation: The case of the clouded apollo. AB - This article discusses the influence of phenology-related intraseasonal asynchrony on metapopulation dynamics and stability. As the part played by intraseasonal asynchrony is as yet unclear and poorly described, greater account of it should be taken in both metapopulation research and conservation practice. The subpopulations of the Parnassius mnemosyne metapopulation studied here are strongly isolated because of the phenological shift between them, despite the relatively small physical distances between them. This isolation is the result of a significant temporal shift in the species' flight periods in the main metapopulation centers: in some seasons its flight times in the different subpopulations did not overlap at all. The predicted results of such strong intraseasonal asynchrony are not altogether clear. On the one hand, they reduce the vulnerability of the entire metapopulation to the effects of short-term random disasters. On the other, the ever-greater isolation of subpopulations may cause the metapopulation to become a nonequilibrium one, which will have a serious impact on its long-term survival. PMID- 29573161 TI - Association between pain control and patient satisfaction outcomes in the emergency department setting. AB - OBJECTIVE: Pain management and patient satisfaction are key markers for health systems performance. There is a lack of consensus on the role of analgesia, its adequacy, and its links to patient satisfaction in the ED. The present study aimed to assess the relationship between adequacy of analgesia and patient satisfaction in the ED setting. METHODS: Consenting adult patients (n = 115) presenting to the ED with pain were enrolled, and their pain tracked throughout admission with 11 point numerical pain scores. Eleven point numerical scores were also utilised to measure satisfaction and compassion at the end of each ED stay. The primary outcome was patient satisfaction score >=7. RESULTS: Of 115 enrolled patients, 94 (81.7%) were eligible for analysis. Median time to physician evaluation was 54.0 min (inter-quartile range [IQR] 35.0-98.0) and median ED length of stay was 205 min (IQR 129.0-280.0). Fifty-four patients (57.5%) received analgesia during their stay, of whom 36 (38.3%) had a significant response to analgesia (>=2 change in pain score). Median time to analgesia was 87.5 min (IQR 66.1-108.9). Patient satisfaction was inversely associated with male sex, and positively correlated (Spearman's rank correlation P < 0.05) with increasing age, significant change in pain score (+/-2) and compassion scores. CONCLUSION: In the present study of patients presenting to the ED with pain, oligoanalgesia remains a significant issue. Male sex was inversely associated with satisfaction, whereas compassion, and significant change in pain score were associated with improved patient satisfaction. Of the factors analysed, staff compassion demonstrated the strongest correlation with satisfaction. PMID- 29573162 TI - Changing environment of hyperglycemia in pregnancy: Gestational diabetes and diabetes mellitus in pregnancy. AB - The diagnosis and treatment of gestational diabetes mellitus (GDM) have been in a state of flux since the World Health Organization accepted and endorsed the International Diabetes and Pregnancy Study Group's diagnostic pathway and criteria in 2013. These new diagnostic criteria identify an increasing number of women at risk of hyperglycemia in pregnancy (HGiP). Maternal hyperglycemia represents a significant risk to the mother and fetus, in both the short and long term. Controversially, metformin use for the treatment of GDM is increasing in Australia. This article identifies the multiple and varied presentations of HGiP, of which GDM is the most commonly encountered. The degree of maternal hyperglycemia experienced affects the outcomes for both the mother and neonate, and specific diagnosis determines the appropriate treatment for the pregnancy. Given the increasing incidence of women with dysglycemia and those developing HGiP, this is an important area for research and clinical attention for all health professionals.

AB - Periprosthetic infection via skin-implant interface is a leading cause of failures and revisions in direct skeletal attachment of limb prostheses. Implants with deep porosity fabricated with skin and bone integrated pylons (SBIP) technology allow for skin ingrowth through the implant's structure creating natural barrier against infection. However, until the skin cells remodel in all pores of the implant, additional care is required to prevent from entering bacteria to the still nonoccupied pores. Temporary silver coating was evaluated in this work as a means to provide protection from infection immediately after implantation followed by dissolution of silver layer in few weeks. A sputtering coating with 1 um thickness was selected to be sufficient for fighting infection until the deep ingrowth of skin in the porous structure of the pylon is completed. In vitro study showed less bacterial (Staphylococcus aureus, Staphylococcus epidermidis, and Pseudomonas aeruginosa) growth on silver coated tablets compared to the control group. Analysis of cellular density of MG-63 cells, fibroblasts, and mesenchymal stem cells (MSCs) showed that silver coating did not inhibit the cell growth on the implants and did not affect cellular functional activity. The in vivo study did not show any postoperative complications during the 6-month observation period in the model of above-knee amputation in rabbits when SBIP implants, either silver-coated or untreated were inserted into the bone residuum. Three-phase scintigraphy demonstrated angiogenesis in the pores of the pylons. The findings suggest that a silver coating with well-chosen specifications can increase the safety of porous implants for direct skeletal attachment. (c) 2018 Wiley Periodicals, Inc.

AB - INTRODUCTION: Games involving technology have the potential to enhance hand-eye coordination and decision-making skills. As a result, game characteristics have been applied to education and training, where they are known as serious games. There is an increase in the volume of literature on serious games in healthcare education; however, evidence on their impact is still ambiguous. AIMS: The aims of this study were (i) to identify high-quality evidence (systematic reviews or meta-analyses) regarding impacts of serious games on healthcare education; and (ii) to explore evidence regarding impacts of serious games in dental education. METHODS: A rapid review of the literature was undertaken to synthesise available evidence and examine serious games in healthcare education (Stage 1) and dental education (Stage 2). RESULTS: Nine systematic reviews were included in Stage 1, four of which were of high, three of moderate and two of low quality. For Stage 2, two randomised control trials with moderate quality were included. The findings demonstrated that serious games are potentially effective learning tools in terms of knowledge and skills improvement, although outcomes of serious games over traditional learning approaches were not consistent. In addition, serious games appeared to be more engaging and satisfying for students, which could be considered as the most important positive impact. CONCLUSION: Serious games provide an option for healthcare and dental education but remain underutilised and researched. At best, they offer a similar experience to other methods in relation to educational outcome; however, they can provide a supplementary strategy to engage students and improve learner satisfaction. PMID- 29573164 TI - Patient receipt of smoking cessation care in four Australian acute psychiatric facilities. AB - This study aimed to report the receipt of smoking care, and associated clinical and smoking characteristics among smokers admitted to four public psychiatric inpatient facilities in New South Wales, Australia. Between October 2012 and July 2014, adult smokers (N = 236) were surveyed during admission to and 1 month following discharge from the facilities. Measures of smoking care receipt were reported descriptively, and logistic regression analyses were used to explore characteristics associated with care receipt. The majority of participants were offered (78%) and used (78%) nicotine replacement therapy (NRT), with 66% of NRT users reporting the amount provided was sufficient to reduce cravings. A minority of participants (16%) received information or advice to quit smoking, and 60% reported smoking throughout their admission. Patients not contemplating quitting and those with non-psychotic disorders were more likely to receive an offer of NRT. The findings suggest the provision of smoking care in Australian acute psychiatric units is sub-optimal overall, with an indication that care may be provided selectively to certain patients, rather than systematically to all. Development and dissemination of interventions to increase smoking care provision in inpatient psychiatry are needed. PMID- 29573166 TI - Suboptimal behaviour and knowledge regarding overnight glycaemia in adults with type 1 diabetes is common. AB - BACKGROUND: In people with type 1 diabetes (T1D), nocturnal hypoglycaemia (NH) can be slept through and can cause seizures, arrhythmias and death. Hypoglycaemia avoidance can induce hyperglycaemia and ketosis. Patient behaviour impacts clinical outcomes and may be changed by education. AIM: To develop and utilise a survey to evaluate patient self-management of overnight glycaemia in adults with T1D. METHODS: Adults with T1D attending two Australian tertiary referral diabetes clinics completed a survey about their diabetes self-management and glycaemic control, including responses to hypothetical pre-bed blood glucose (BG) levels (4 20 mmol/L). Statistical analyses included t-tests, Chi square tests and ANOVA with significance considered at P < 0.05. RESULTS: There were 205 participants (103 females), with a mean (SD) age of 41 (17) years, T1D duration of 20 (16) years, HbA1c of 7.8(1.4)%, (61.3(8.2) mmol/mol), 38% on insulin pump therapy (CSII) and 36% with impaired hypoglycaemia awareness (IHA). Mean (SD) number of BG tests/day was 5.4 (2.7). Patients set higher BG target levels at bedtime and overnight: 7.5(1.4) and 7.1(1.3) mmol/L, respectively, compared to daytime (6.9(1.0); P < 0.0001 and P = 0.002 respectively). Only 36% of participants reported treating nocturnal hypoglycaemia (NH) with the recommended refined, then complex, carbohydrate. Only 28% of patients made safe choices in all bedtime BG scenarios, with higher rates for CSII users, P = 0.0005. Further education was desired by 32% of respondents, with higher rates in those with (44%) versus without IHA (25%), P = 0.006. CONCLUSIONS: Many adults with T1D have suboptimal knowledge and behaviour regarding overnight BG self-management. A survey, piloted herein, may facilitate the identification of patients who could benefit from further education. PMID- 29573167 TI - Effects of transcranial pulsed electromagnetic field stimulation on quality of life in Parkinson's disease. AB - BACKGROUND AND PURPOSE: Pulsed electromagnetic fields induce a protective and anti-inflammatory effect in the nervous system primarily due to growth factor upregulation that possibly abates neurodegeneration in Parkinson's disease (PD). This study investigated treatment effects of transcranial pulsed electromagnetic fields (T-PEMFs) on quality of life in PD and the feasibility and safety of this treatment. METHODS: In this double-blinded clinical study, 97 participants with idiopathic PD (Hoehn & Yahr stage I-IV), on optimal medical anti-parkinsonian treatment, were block randomized (3:3) to either active (n = 49) or placebo treatment (n = 48). Treatment with T-PEMFs entailed one daily 30-min home treatment for eight consecutive weeks. The 39-item Parkinson's Disease Questionnaire (PDQ-39) was assessed at baseline and endpoint. A special questionnaire was used to profile adverse events by interviewing the participants over the full treatment period. Treatment compliance was accounted for by daily treatment registration. RESULTS: The active group improved with respect to clinical effect size for the two dimensions, i.e. mobility and activities of daily living, compared with the placebo group. No between-group differences were found for the remaining PDQ-39 dimensions. There were no between-group difference in adverse events. Treatment compliance was 97.9%. CONCLUSION: Treatment with T PEMFs improved mobility and activities of daily living scores for clinical effect size only in the active group, indicating a positive treatment response for motor symptoms. No difference was found between the two groups for the remaining PDQ-39 dimensions. The treatment had no or only mild adverse events and was performed with high compliance. PMID- 29573168 TI - Plant G proteins interact with endoplasmic reticulum luminal protein receptors to regulate endoplasmic reticulum retrieval. AB - Maintaining endoplasmic reticulum (ER) homeostasis is essential for the production of biomolecules. ER retrieval, i.e., the retrograde transport of compounds from the Golgi to the ER, is one of the pathways that ensures ER homeostasis. However, the mechanisms underlying the regulation of ER retrieval in plants remain largely unknown. Plant ERD2-like proteins (ERD2s) were recently suggested to function as ER luminal protein receptors that mediate ER retrieval. Here, we demonstrate that heterotrimeric G protein signaling is involved in ERD2 mediated ER retrieval. We show that ERD2s interact with the heterotrimeric G protein Galpha and Ggamma subunits at the Golgi. Silencing of Galpha, Gbeta, or Ggamma increased the retention of ER luminal proteins. Furthermore, overexpression of Galpha, Gbeta, or Ggamma caused ER luminal proteins to escape from the ER, as did the co-silencing of ERD2a and ERD2b. These results suggest that G proteins interact with ER luminal protein receptors to regulate ER retrieval. PMID- 29573169 TI - Transcriptome-Based Analysis in Lactobacillus plantarum WCFS1 Reveals New Insights into Resveratrol Effects at System Level. AB - SCOPE: This study was undertaken to expand our insights into the mechanisms involved in the tolerance to resveratrol (RSV) that operate at system-level in gut microorganisms and advance knowledge on new RSV-responsive gene circuits. METHODS AND RESULTS: Whole genome transcriptional profiling was used to characterize the molecular response of Lactobacillus plantarum WCFS1 to RSV. DNA repair mechanisms were induced by RSV and responses were triggered to decrease the load of copper, a metal required for RSV-mediated DNA cleavage, and H2 S, a genotoxic gas. To counter the effects of RSV, L. plantarum strongly up- or downregulated efflux systems and ABC transporters pointing to transport control of RSV across the membrane as a key mechanism for RSV tolerance. L. plantarum also downregulated tRNAs, induced chaperones, and reprogrammed its transcriptome to tightly control ammonia levels. RSV induced a probiotic effector gene and a likely deoxycholate transporter, two functions that improve the host health status. CONCLUSION: Our data identify novel protective mechanisms involved in RSV tolerance operating at system level in a gut microbe. These insights could influence the way RSV is used for a better management of gut microbial ecosystems to obtain associated health benefits.

PMID- 29573172 TI - Quantification of Urinary Protein Biomarkers of Autosomal Dominant Polycystic Kidney Disease by Parallel Reaction Monitoring. AB - PURPOSE: Autosomal dominant polycystic kidney disease (ADPKD) is a life-long disease in which the genes responsible are known, but the pathogenesis of cyst formation and cyst growth are not understood. Cyst growth ultimately leads to end stage renal failure in most patients. Analysis of the urinary proteome offers the potential to identify proteins that indicate the presence of cysts (and thus provides diagnosis) as well as the rates of cyst growth (providing prognostic information). EXPERIMENTAL DESIGN: A scheduled parallel reaction monitoring (sPRM) assay is performed on urine samples from 14 patients and 18 normal controls. For relative quantification, stable isotope-labeled synthetic peptides are spiked in the urinary protein digests prior to data collection. The data are subsequently normalized to creatinine and protein concentration in the respective urine samples to control for variations in water intake between individuals. RESULTS: Out of the 143 urinary proteins targeted for sPRM assay, 69 proteins are observed to be significantly dysregulated in ADPKD. The dysregulated proteins are used to cluster ADPKD patients into those who are more or less similar to normal controls. CONCLUSIONS AND CLINICAL RELEVANCE: This study shows that sPRM is a promising approach to rapidly screen large numbers of proteins in urine in order to provide earlier diagnosis and potentially better understand the pathogenesis of ADPKD development and progression.

AB - The aim of this study was to explore the unique imaging abilities of optoacoustic mesoscopy to visualize skin structures and microvasculature with the view of establishing a robust approach for monitoring heat-induced hyperemia in human skin in vivo. Using raster-scan optoacoustic mesoscopy (RSOM), we investigated whether optoacoustic (photoacoustic) mesoscopy can identify changes in skin response to local heating at microvasculature resolution in a cross-sectional fashion through skin in the human forearm. We visualized the heat-induced hyperemia for the first time with single-vessel resolution throughout the whole skin depth. We quantified changes in total blood volume in the skin and their correlation with local heating. In response to local heating, total blood volume increased 1.83- and 1.76-fold, respectively, in the volar and dorsal aspects of forearm skin. We demonstrate RSOM imaging of the dilation of individual vessels in the skin microvasculature, consistent with hyperemic response to heating at the skin surface. Our results demonstrate great potential of RSOM for elucidating the morphology, functional state and reactivity of dermal microvasculature, with implications for diagnostics and disease monitoring. Image: Cross-sectional view of skin microvasculature dilated in response to hyperthermia. PMID- 29573175 TI - One anastomosis gastric bypass versus Roux-en-Y gastric bypass for morbid obesity: a meta-analysis. AB - We aim to review the available literature on morbidly obese patients treated with one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) in order to compare the clinical outcomes of the two methods. A literature search was performed in PubMed, Cochrane library and Scopus, in accordance with the PRISMA guidelines. Twelve studies met the inclusion criteria (7452 patients). OAGB was associated with shorter mean operative time. The length of hospital stay was comparable between the two procedures. The incidence of leaks, marginal ulcer, dumping, bowel obstruction, revisions and mortality was similar between the two approaches. The incidence of malnutrition was increased in patients treated with OAGB, while the incidence of internal hernia and bowel obstruction was greater in the RYGB group. In addition, the percentage excess weight loss at 1, 2 and 5 years post-operatively was greater for the OAGB group. The rate of type 2 diabetes remission was greater in the OAGB group. The rate of hypertension and dyslipidemia remission was also similar between OAGB and RYGB. Randomized controlled trials, comparing RYGB to OAGB, are necessary to further assess their clinical outcomes. PMID- 29573176 TI - Thunderstorm Asthma - Revealing a hidden at-risk population. AB - BACKGROUND & AIM: To characterise the nature and extent of respiratory symptoms in healthcare workers during the Melbourne Thunderstorm Asthma event. METHODS: A survey was conducted among staff and volunteers across Eastern Health, distributed on the intranet homepage, by e-mail, and by word of mouth. Anonymous survey questions were constructed to assess prior and current diagnoses of relevance, symptoms, and demography. RESULTS: There were 515 participants (80% female, n=411) who completed the survey of approximately 9000 potential respondents (~6% response rate). 132 (25.6%) had symptoms suggestive of asthma during the ETSA event, the majority of which did not seek professional medical help. Notably, of those with ETSA-like symptoms, only 58 (43.9%) had a history of asthma while 97 (73.5%) had a history of allergic rhinitis. Specifically, a history of allergic rhinitis (OR 2.77, p < 0.001), a history of asthma (OR 1.67, p = 0.037), and being of self-identified Asian ethnicity (OR 3.24, p < 0.001) were all strong predictors of ETSA-like symptoms. Being predominantly indoors was not protective. CONCLUSIONS: Our study provides evidence for the presence of a large cohort of sufferers during the Melbourne Thunderstorm Asthma event of 2016 that did not come to the attention of medical services, implying a potentially hidden and significant susceptible population. Further research should help clarify the true prevalence of vulnerability in the general population, with important public health implications. PMID- 29573177 TI - A four-season longitudinal study of enterohaemorrhagic Escherichia coli in beef cow-calf herds in Mississippi and Nebraska. AB - Our objective was to describe the probability of detecting seven serogroups of enterohaemorrhagic Escherichia coli (EHEC-7) of public health importance in faecal samples from beef cow-calf herds and to test for factors associated with their detection. Fresh faecal samples (n = 85) from two Mississippi and two Nebraska herds were collected in each of four seasons. Samples were tested for each EHEC-7 serogroup by a molecular screening assay. Separate management groups within herds were sampled, and group-level factors were recorded. To measure the effects of factors on faecal shedding of EHEC-7, separate multivariable logistic regression models were used, accounting for the random effect of clustering by group within farm. Statistical significance was set alpha = 0.05. Fifty-nine samples (4.3%) were positive for EHEC O26, and Nebraska samples were more likely to be positive than Mississippi samples (OR = 12.4, 95% CI: 1.1, 139.2). Forty four samples (3.2%) were positive for EHEC O45. Odds for detection were greater in the summer than all other seasons combined (OR = 4.2, 95% CI: 1.3, 14.0), and odds decreased if a precipitation event occurred (OR = 0.07, 95% CI: 0.006, 0.8). EHEC O103 was detected in 66 samples (4.9%) with increased probability to be detected at increased temperature. EHEC O111 was detected in 71 samples (5.2%), and 43 samples (3.2%) were positive for EHEC O145. Both EHEC O111 and O145 were associated separately with season, with greater probability for detection in the summer. Eighteen (1.3%) and 68 (5.0%) samples were positive for EHEC O121 and EHEC O157, respectively. We failed to detect significant explanatory factors associated with probability to detect EHEC O121 or O157. Factors that vary by time and place, such as precipitation, ambient temperature, region and season, are uniquely associated with the probability to detect EHEC-7 in fresh faeces collected from cow-calf herds. PMID- 29573178 TI - On the role of interference in laser-based mid-infrared widefield microspectroscopy. AB - A laser's high degree of coherence leads to interferences, which-in the absence of precautions-can cause severe image distortions such as fringes and speckles and which thereby strongly hamper a meaningful interpretation of hyperspectral images in laser-based widefield microspectroscopy. While images and spectra of homogenous samples may already suffer from interferences, any structured object such as a tissue thin section will add to these distortions due to wavelength- and, in particular, sample-dependent phase shifts (structure sizes, absorption coefficients, refractive indices). This effect is devastating for the universal applicability of laser-based microspectroscopy especially in the mid-infrared (MIR), where cell sizes are of the same dimension as the wavelength of the illumination source. Here, we show that the impact of interferences is strongly mitigated by reducing the time-averaged spatiotemporal coherence properties of the illumination using a moving plus a stationary scatterer. In this case, the illumination path provides a pseudothermal radiation source and spatially resolved spectra can be obtained at the quality of the reference method, that is, Fourier-transform infrared microspectroscopy, without compromising spectral or spatial resolution. PMID- 29573179 TI - Towards robot-assisted anchor deployment in beating-heart mitral valve surgery. AB - BACKGROUND: Beating-heart intracardiac surgery promises significant benefits for patients compared with cardiopulmonary bypass based procedures. However, the fast motions of the heart introduce serious challenges for surgeons. METHODS: In this work, a new impedance-controlled master-slave telerobotic system is developed to help perform anchor deployment for mitral valve annuloplasty under the guidance of live ultrasound images of the heart. The proposed bilateral teleoperation system can both reflect the non-oscillatory portion of slave-heart tissue interaction force on the surgeon's hand as haptic feedback and implement rapid compensation for the beating heart's motion. The surgical task involves performing anchor deployment on a simulated moving heart tissue to evaluate the effectiveness of the proposed strategy for safely interacting with a moving organ. RESULTS AND CONCLUSIONS: The results obtained show that the telerobotic system increases the success rate of anchor deployment by 100% and reduces the excess force application rate by 70% compared with manual attempts. PMID- 29573180 TI - A comparison of methods for meta-analysis of a small number of studies with binary outcomes. AB - Meta-analyses often include only a small number of studies (<=5). Estimating between-study heterogeneity is difficult in this situation. An inaccurate estimation of heterogeneity can result in biased effect estimates and too narrow confidence intervals. The beta-binominal model has shown good statistical properties for meta-analysis of sparse data. We compare the beta-binominal model with different inverse variance random (eg, DerSimonian-Laird, modified Hartung Knapp, and Paule-Mandel) and fixed effects methods (Mantel-Haenszel and Peto) in a simulation study. The underlying true parameters were obtained from empirical data of actually performed meta-analyses to best mirror real-life situations. We show that valid methods for meta-analysis of a small number of studies are available. In fixed effects situations, the Mantel-Haenszel and Peto methods performed best. In random effects situations, the beta-binominal model performed best for meta-analysis of few studies considering the balance between coverage probability and power. We recommended the beta-binominal model for practical application. If very strong evidence is needed, using the Paule-Mandel heterogeneity variance estimator combined with modified Hartung-Knapp confidence intervals might be useful to confirm the results. Notable most inverse variance random effects models showed unsatisfactory statistical properties also if more studies (10-50) were included in the meta-analysis.

PMID- 29573182 TI - Variations of pulmonary vein drainage critical for lung resection assessed by three-dimensional computed tomography angiography. AB - BACKGROUND: It is important to understand pulmonary vein drainage pattern variations and their frequency in order to perform safe anatomical pulmonary resection. METHODS: Variations and frequencies were assessed using three dimensional computed tomography angiography (3D-CT) in 194 patients. In cases where the tumor or lymph node caused atelectasis or compression of hilar structures, the involved lobes were excluded from the analyses. RESULTS: We confirmed variant drainage patterns in 15/189 (8.0%) patients in the right upper lobe (RUL), 29/189 (15.3%) in the right middle lobe (RML), 18/192 (9.5%) in the right lower lobe (RLL), and 5/187 (2.6%) in the left upper lobe (LUL). There was no variant type in the left lower lobe (LLL). There were 14 (7.4%) cases of anomalous superior posterior pulmonary vein of RUL (V2 ) drainage: V2 draining to the superior pulmonary vein (SPV) (n = 2, 1.1%), V2 to the inferior pulmonary vein (IPV) (n = 7, 3.7%), V2 to the left atrium (LA) (n = 2, 1.1%), and V6 to the apical pulmonary vein of the RLL (n = 3, 1.6%). There was a posterior pulmonary vein, V3 to RML pulmonary vein in one case (0.5%). The RML pulmonary vein drained into the IPV in 14 (7.4%) and into the LA in 15 (7.9%) cases. The right V6 directly drained into the LA in 15 (7.9%) and V6 into the SPV in 3 (1.6%) cases. The lingular pulmonary vein drained into the IPV in one case (0.5%) and into the LA in two cases (1.1%). The inferior lingular pulmonary vein V5 drained into the IPV and into the LA in one case (0.5%), respectively. CONCLUSION: We describe anomalous pulmonary venous drainage patterns and their frequencies particular to anatomic surgical resection. 3D-CT is useful to find such variations. PMID- 29573183 TI - Label-free quantitative chemical imaging and classification analysis of adipogenesis using mouse embryonic stem cells. AB - Stem cells have received much attention recently for their potential utility in regenerative medicine. The identification of their differentiated progeny often requires complex staining procedures, and is challenging for intermediary stages which are a priori unknown. In this work, the ability of label-free quantitative coherent anti-Stokes Raman scattering (CARS) micro-spectroscopy to identify populations of intermediate cell states during the differentiation of murine embryonic stem cells into adipocytes is assessed. Cells were imaged at different days of differentiation by hyperspectral CARS, and images were analysed with an unsupervised factorization algorithm providing Raman-like spectra and spatially resolved maps of chemical components. Chemical decomposition combined with a statistical analysis of their spatial distributions provided a set of parameters that were used for classification analysis. The first 2 principal components of these parameters indicated 3 main groups, attributed to undifferentiated cells, cells differentiated into committed white pre-adipocytes, and differentiating cells exhibiting a distinct protein globular structure with adjacent lipid droplets. An unsupervised classification methodology was developed, separating undifferentiated cell from cells in other stages, using a novel method to estimate the optimal number of clusters. The proposed unsupervised classification pipeline of hyperspectral CARS data offers a promising new tool for automated cell sorting in lineage analysis. PMID- 29573184 TI - Batch effects in a multiyear sequencing study: False biological trends due to changes in read lengths. AB - High-throughput sequencing is a powerful tool, but suffers biases and errors that must be accounted for to prevent false biological conclusions. Such errors include batch effects; technical errors only present in subsets of data due to procedural changes within a study. If overlooked and multiple batches of data are combined, spurious biological signals can arise, particularly if batches of data are correlated with biological variables. Batch effects can be minimized through randomization of sample groups across batches. However, in long-term or multiyear studies where data are added incrementally, full randomization is impossible, and batch effects may be a common feature. Here, we present a case study where false signals of selection were detected due to a batch effect in a multiyear study of Alpine ibex (Capra ibex). The batch effect arose because sequencing read length changed over the course of the project and populations were added incrementally to the study, resulting in nonrandom distributions of populations across read lengths. The differences in read length caused small misalignments in a subset of the data, leading to false variant alleles and thus false SNPs. Pronounced allele frequency differences between populations arose at these SNPs because of the correlation between read length and population. This created highly statistically significant, but biologically spurious, signals of selection and false associations between allele frequencies and the environment. We highlight the risk of batch effects and discuss strategies to reduce the impacts of batch effects in multiyear high-throughput sequencing studies. PMID- 29573185 TI - Epigastric hernia contiguous with the laparoscopic port site after endoscopic robotic total prostatectomy. AB - Both laparoscopic and endoscopic robotic surgery are widely accepted for many abdominal surgeries. However, the port site for the laparoscope cannot be easily sutured without defect, particularly in the cranial end; this can result in a port-site incisional hernia and trigger the progressive thinning and stretching of the linea alba, leading to epigastric hernia. In the present case, we encountered an epigastric hernia contiguous with an incisional scar at the port site from a previous endoscopic robotic total prostatectomy. Abdominal ultrasound and CT revealed that the width of the linea alba was 30-48 mm. Previous CT images prepared before endoscopic robotic prostatectomy had shown a thinning of the linea alba. We should be aware of the possibility of epigastric hernia after laparoscopic and endoscopic robotic surgery. In laparoscopic and endoscopic robotic surgery for a high-risk patient for epigastric hernia, we should consider additional sutures cranial to the port-site incision to prevent of an epigastric hernia. PMID- 29573186 TI - A high-density SNP chip for genotyping great tit (Parus major) populations and its application to studying the genetic architecture of exploration behaviour. AB - High-density SNP microarrays ("SNP chips") are a rapid, accurate and efficient method for genotyping several hundred thousand polymorphisms in large numbers of individuals. While SNP chips are routinely used in human genetics and in animal and plant breeding, they are less widely used in evolutionary and ecological research. In this article, we describe the development and application of a high density Affymetrix Axiom chip with around 500,000 SNPs, designed to perform genomics studies of great tit (Parus major) populations. We demonstrate that the per-SNP genotype error rate is well below 1% and that the chip can also be used to identify structural or copy number variation. The chip is used to explore the genetic architecture of exploration behaviour (EB), a personality trait that has been widely studied in great tits and other species. No SNPs reached genomewide significance, including at DRD4, a candidate gene. However, EB is heritable and appears to have a polygenic architecture. Researchers developing similar SNP chips may note: (i) SNPs previously typed on alternative platforms are more likely to be converted to working assays; (ii) detecting SNPs by more than one pipeline, and in independent data sets, ensures a high proportion of working assays; (iii) allele frequency ascertainment bias is minimized by performing SNP discovery in individuals from multiple populations; and (iv) samples with the lowest call rates tend to also have the greatest genotyping error rates. PMID- 29573187 TI - Propensity-Matched Analysis of Patients with Mixed Hepatocellular Cholangiocarcinoma and Hepatocellular Carcinoma Undergoing Liver Transplantation. AB - Mixed hepatocellular-cholangiocarcinomas (HCC-CCAs) are rare tumors with both hepatocellular and biliary differentiation. While liver transplantation (LT) is the gold standard treatment for patients with unresectable hepatocellular carcinoma (HCC), it is contraindicated in known HCC-CCA because of concerns of poor prognosis. We sought to compare posttransplant oncologic outcomes for HCC CCA and a matched cohort of HCC LT recipients. A retrospective, single-center analysis (1984-2015) identified 12 patients with mixed HCC-CCA who were matched 1:3 to patients with HCC on both pretransplant (radiologic diameter and alpha fetoprotein) and explant (pathologic diameter, grade/differentiation, and vascular invasion) tumor characteristics. Compared with HCC patients matched on pretransplant characteristics (n = 36), HCC-CCA had higher explant tumor grade, more poorly differentiated tumors, but similar T stage and vascular invasion. HCC CCA recipients trended toward inferior recurrence-free survival at 5 years (28% versus 61%; P = 0.12) and greater recurrence (HCC-CCA: 50%, median time to recurrence 297 days versus HCC: 22%, median time to recurrence 347 days; P = 0.07). However, when matched to a separate HCC cohort with similar explant pathology, HCC-CCA had similar 5-year recurrence-free survival (42% versus 44%; P = 0.45) and posttransplant recurrence (50% versus 27%; P = 0.13). All 6 HCC-CCA recurrences occurred with poorly differentiated tumors (median survival 21.3 months), without a single recurrence in 5 of the 12 HCC-CCA patients with well moderately differentiated tumors (median survival 60.2 months). Mixed HCC-CCA tumors are more likely poorly differentiated tumors compared with HCC with similar pretransplant characteristics. However, compared with HCC with similar pathologic characteristics, they display similar recurrence-free survival and are not inherently more aggressive tumors. Low-grade, well-moderately differentiated HCC-CCAs have excellent survival with a low risk for post-LT recurrence, and they should not be excluded from LT. Improved pretransplant identification of pathologic characteristics in HCC-CCA may allow for successful utilization of LT in this subset of patients.

AB - Herein, we combine the ideas of concerted emission from fluorophore ensembles and its further amplification through FRET in an organic-inorganic hybrid approach. Spherical and highly fluorescent organic nanoparticles (FONPs, Phif =0.38), prepared by the self-assembly of oligo(phenylene ethynylene) (OPE) molecules, were selected as a potential donor material. This organic core was then decorated with a shell of fluorescent CdSe/ZnS core-shell quantum dots (QDs; ?5.5 nm, Phif =0.27) with the aid of a bifunctional ligand, mercaptopropionic acid. Its high extinction coefficient (epsilon~4.1*105 m-1 cm-1 ) and good spectral match with the emission of the FONPs (J(lambda)~4.08*1016 m-1 cm-1 nm4 ) made them a better acceptor candidate to constitute an efficient FRET pair (PhiFRET =0.8). As a result, the QD fluorescence intensity was enhanced by more than twofold. The fundamental calculations carried out indicated an improvement in all the FRET parameters as the number of QDs around the FONPs was increased. This, together with the localization of multiple QDs in a nanometric dimension (volume~1.8*106 nm3 ), gave highly bright reddish luminescent hybrid particles as visualized under a fluorescence microscope. PMID- 29573189 TI - Assessment of physical activity intensity and duration in the paediatric population: evidence to support an a priori hypothesis and sample size in the agreement between subjective and objective methods. AB - We aimed to provide evidence for an a priori hypothesis and sample size for subjectively assessing physical activity intensity and duration in paediatric population, adopting objective methods as the reference. We searched electronic databases, reference lists and author databases. Correlation coefficients were pooled as an indicator of agreement estimates. We found 183 agreement analyses (94.5% based on correlation coefficients) from 89 studies that met our inclusion criteria. We identified four physical activity parameters addressing intensity and two parameters addressing duration. The physical activity parameters focusing on intensity were measured only by questionnaires, and the best correlation was achieved by moderate-to-vigorous physical activity compared with a heart rate monitor. In addition, total physical activity duration had a stronger correlation with an accelerometer when measured by diaries or logs than when measured by questionnaires. In both cases, the correlation was moderate. Studies with sample sizes between 50 and 99 subjects showed measurements that were stable in both magnitude and interpretation. Our findings suggest that the agreement between subjective and objective methods for assessing physical activity intensity and duration is weak to moderate. Furthermore, sample sizes ranging from 50 to 99 subjects provide stable agreement estimates between methods. PMID- 29573190 TI - Infective endocarditis: a Hunter New England perspective. AB - BACKGROUND: Infective endocarditis (IE) is a severe infection conferring significant morbidity and mortality. It is associated with geographical variation, complicating diagnosis and treatment of patients in a standardised manner. AIM: To evaluate the presentation, treatment and outcomes of patients with IE in the Hunter New England Local Health District (HNELHD). METHODS: A total of 112 patients with definite IE admitted to hospitals within the HNELHD between 2011 and 2015 was retrospectively analysed. RESULTS: The mean age of patients was 56.8 (standard deviation 20.3) and 62.5% were male. The most common valve affected was the mitral valve, in 41% of patients, and the most common organism was Staphylococcus aureus, in 47.7% of patients. A history of IE was present in 10% of patients and 19.6% presented with prosthetic valve IE. Survival among patients treated surgically was 100% at 30 days, 92% at 1 year and 83% at 3 years, versus 82% at 30 days, 65% at 1 year and 51% at 3 years for those not operated (P = 0.004). Valve type, organism and Australian Standard Geographical Classification remoteness area did not have a statistically significant effect on mortality (P-value 0.095, 0.456 and 0.186, respectively). Factors associated with improved survival by univariate analysis included surgery and multidisciplinary team review. CONCLUSION: IE in the HNELHD affects a relatively young cohort of patients and is associated with a high mortality. Outcomes could be improved by implementation of a multidisciplinary team approach and inpatient cardiac surgery. PMID- 29573191 TI - Is fascial defect closure with intraperitoneal onlay mesh superior to standard intraperitoneal onlay mesh for laparoscopic repair of large incisional hernia? AB - INTRODUCTION: The ideal surgical technique for large incisional hernia repair has not yet been identified. The aim of this study was to evaluate surgical outcomes of standard intraperitoneal onlay mesh (sIPOM) versus fascial defect closure with intraperitoneal onlay mesh (IPOM-Plus) for large incisional hernia repair. METHODS: Of 49 patients who underwent laparoscopic incisional hernia repair between November 2005 and December 2016, 26 cases with large incisional hernia (transverse diameter >=10 cm) were examined to compare surgical outcomes between sIPOM (n = 12) and IPOM-Plus (n = 14). Statistical analysis was performed using the Mann-Whitney U-test and Fisher's exact test. P < 0.05 was considered to be statistically significant. RESULTS: We compared sIPOM with IPOM-Plus for similar hernia types during median follow-up periods of 53 and 21 months, respectively. The operation time was 150 min for sIPOM and 148 min for IPOM-Plus (P = 0.6220). Early postoperative complications including seroma formation were observed in four sIPOM patients (33%) and three IPOM-Plus patients (21%) (P = 0.6652). Significantly more mesh bulged with sIPOM than with IPOM-Plus (50% vs 0%; P = 0.0082). Chronic pain lasting 3 months after the operation was found in two cases of IPOM-Plus (14%), but this was not statistically significant. Postoperative hospital stay was longer for sIPOM patients than for IPOM-Plus patients. Only one recurrence was observed in the sIPOM group (8%), but this was not statistically significant. CONCLUSION: For large incisional hernia repair, IPOM-Plus seems to be more effective than sIPOM in terms of reducing mesh bulging. PMID- 29573192 TI - Responses of fungal community composition to long-term chemical and organic fertilization strategies in Chinese Mollisols. AB - How fungi respond to long-term fertilization in Chinese Mollisols as sensitive indicators of soil fertility has received limited attention. To broaden our knowledge, we used high-throughput pyrosequencing and quantitative PCR to explore the response of soil fungal community to long-term chemical and organic fertilization strategies. Soils were collected in a 35-year field experiment with four treatments: no fertilizer, chemical phosphorus, and potassium fertilizer (PK), chemical phosphorus, potassium, and nitrogen fertilizer (NPK), and chemical phosphorus and potassium fertilizer plus manure (MPK). All fertilization differently changed soil properties and fungal community. The MPK application benefited soil acidification alleviation and organic matter accumulation, as well as soybean yield. Moreover, the community richness indices (Chao1 and ACE) were higher under the MPK regimes, indicating the resilience of microbial diversity and stability. With regards to fungal community composition, the phylum Ascomycota was dominant in all samples, followed by Zygomycota, Basidiomycota, Chytridiomycota, and Glomeromycota. At each taxonomic level, the community composition dramatically differed under different fertilization strategies, leading to different soil quality. The NPK application caused a loss of Leotiomycetes but an increase in Eurotiomycetes, which might reduce the plant fungal symbioses and increase nitrogen losses and greenhouse gas emissions. According to the linear discriminant analysis (LDA) coupled with effect size (LDA score > 3.0), the NPK application significantly increased the abundances of fungal taxa with known pathogenic traits, such as order Chaetothyriales, family Chaetothyriaceae and Pleosporaceae, and genera Corynespora, Bipolaris, and Cyphellophora. In contrast, these fungi were detected at low levels under the MPK regime. Soil organic matter and pH were the two most important contributors to fungal community composition. PMID- 29573193 TI - Importance of the site of positive surgical margin in salvage external beam radiation therapy for biochemical recurrence of prostate cancer after radical prostatectomy. AB - The aim of this study was to examine long-term outcomes in patients who received salvage radiotherapy (SRT) for biochemical recurrence (BRec) of prostate cancer after radical prostatectomy (RP). One hundred and twenty patients with prostate cancer who underwent SRT for BRec after RP without evidence of clinical disease were identified in our institution from 2002 to 2014. Prescription doses to prostate beds were 64.8 Gy with a fractional dose of 1.8 Gy in 96.7% of the patients. In three-dimensional conformal radiation therapy (3D-CRT), the seminal vesicle bed (SVB) was not included in the radiation fields. The prognostic factors for BRec-free survival (BRFS) and incidence of acute and late toxicities were investigated. Median follow-up duration after SRT was 64.9 months. The 5 year rates of BRFS, overall survival (OS), cause-specific survival (CSS), and clinical recurrence-free survival (CRFS) were 39.2%, 98.3%, 97.0%, and 91.9%, respectively. Only two patients experienced late grade 3 toxicity of hematuria. Multivariate analysis revealed that BRFS was significantly favorable in patients with prostate-specific antigen (PSA) values <0.5 ng/mL at the initiation of SRT and pathological Gleason score not including Gleason grade 5. In patients treated with 3D-CRT, a positive surgical margin at the base of the prostate influenced BRFS unfavorably in comparison with positive surgical margins at other sites. SRT for patients with BRec after RP was performed very safely in our institution. However, to improve BRFS, adequate inclusion of the SVB appears mandatory, especially in cases of positive surgical margins at the base of the prostate. PMID- 29573194 TI - Long-term outcomes in patients with nasopharyngeal carcinoma treated with reduced volume conformal radiotherapy: A retrospective cohort study. AB - INTRODUCTION: While the optimal target volumes for primary nasopharyngeal tumour are still subject to debate, we evaluated primary tumour volumes in nasopharyngeal carcinoma (NPC) patients treated according to an institutional protocol with a reduced volume approach and compared them to those determined by Radiation Therapy Oncology Group (RTOG)-0615 guidelines. METHODS: This single centre retrospective analysis included 36 NPC patients treated between 2/2007 and 3/2014. Planning target volume (PTV)-P 50 (50 Gy isodose to the primary tumour) included the gross tumour and the entire nasopharyngeal mucosa (clinical target volume [CTV]-P 50) with 5 mm margins. The PTV-P 50 volumes, as determined by our protocol, were compared to those obtained with RTOG-0615 PTV-P 59.4 (59.4 Gy to the primary tumour). Clinical outcomes were also analysed. RESULTS: Median (range) follow-up: 48 (21-108) months; 88.9% were males; median age was 53 (27 86) years; 14%, 53%, and 33% had stage II, III, and IV disease at diagnosis, respectively. Median volume of PTV-P 50: 209.0 (92.6-568.0) cc. Median volume of RTOG-0615 PTV-P 59.4-P: 292.0 (123.6-425.1) cc. The PTV-P volume was significantly smaller than that delineated according to the RTOG-0615 protocol (p < 0.001). Isolated local relapse as first site of recurrence occurred in five patients: two with stage III, two with IVA and one with IVB disease; all had advanced local disease at diagnosis. All local recurrences occurred in the PTV-P 69-70 region. CONCLUSION: A reduced volume approach for radiotherapy in primary NPC provided acceptable long-term local control. PMID- 29573195 TI - Spindle assembly in egg extracts of the Marsabit clawed frog, Xenopus borealis. AB - Egg extracts of the African clawed frog Xenopus laevis have provided a cell-free system instrumental in elucidating events of the cell cycle, including mechanisms of spindle assembly. Comparison with extracts from the diploid Western clawed frog, Xenopus tropicalis, which is smaller at the organism, cellular and subcellular levels, has enabled the identification of spindle size scaling factors. We set out to characterize the Marsabit clawed frog, Xenopus borealis, which is intermediate in size between the two species, but more recently diverged in evolution from X. laevis than X. tropicalis. X. borealis eggs were slightly smaller than those of X. laevis, and slightly smaller spindles were assembled in egg extracts. Interestingly, microtubule distribution across the length of the X. borealis spindles differed from both X. laevis and X. tropicalis. Extract mixing experiments revealed common scaling phenomena among Xenopus species, while characterization of spindle factors katanin, TPX2, and Ran indicate that X. borealis spindles possess both X. laevis and X. tropicalis features. Thus, X. borealis egg extract provides a third in vitro system to investigate interspecies scaling and spindle morphometric variation. PMID- 29573196 TI - Efatutazone and T0901317 exert synergistically therapeutic effects in acquired gefitinib-resistant lung adenocarcinoma cells. AB - The development of acquired EGFR-TKI therapeutic resistance is still a serious clinical problem in the management of lung adenocarcinoma. Peroxisome proliferator activated receptor gamma (PPARgamma) agonists may exhibit anti-tumor activity by transactivating genes which are closely associated with cell proliferation, apoptosis, and differentiation. However, it remains not clear whether efatutazone has similar roles in lung adenocarcinoma cells of gefitinib resistant such as HCC827-GR and PC9-GR. It has been demonstrated by us that efatutazone prominently increased the mRNA and protein expression of PPARgamma, liver X receptor alpha (LXRalpha),as well as ATP binding cassette subfamily A member 1 (ABCA1). In the presence of GW9662 (a specific antagonist of PPARgamma) or GGPP (a specific antagonist of LXRalpha), efatutazone (40 MUmol/L) restored the proliferation of both HCC827-GR and PC9-GR cells and obviously inhibited the increased protein and mRNA expression of PPAR-gamma, LXR-alpha, and ABCA1 induced by efatutazone. LXRalpha knockdown by siRNA (si-LXRalpha) significantly promoted the HCC827-GR and PC9-GR cells proliferation, whereas incubation efatutazone with si-LXRalpha restored the proliferation ability compared with the control group. In addition, combination of efatutazone and LXRalpha agonist T0901317 showed a synergistic therapeutic effect on lung adenocarcinoma cell proliferation and PPAR gamma, LXR A and ABCA1 protein expression. These results indicate that efatutazone could inhibit the cells proliferation of HCC827-GR and PC9-GR through PPARgamma/LXRalpha/ABCA1 pathway, and synergistic therapeutic effect is achieved when combined with T0901317. PMID- 29573197 TI - Describing symptoms using the Symptom Screening in Pediatrics Tool in hospitalized children with cancer and hematopoietic stem cell transplant recipients. AB - Objectives were to describe any bothersome symptom and severely bothersome symptoms in inpatient children with cancer and hematopoietic stem cell transplant (HSCT) recipients. We included children 8-18 years of age with cancer or HSCT recipients who were receiving active treatment for cancer, admitted to hospital, and expected to be in hospital 3 days later. We administered the self-report Symptom Screening in Pediatrics Tool (SSPedi). We described those who identified any degree of symptom bother (at least "a little") and those who rated the degree of bother as severe ("a lot" or "extremely"). Factors associated with severe symptoms and total SSPedi scores were examined using multiple logistic and linear regression. Among the 302 patients, 298 (98.7%) reported having any bothersome symptom and 181 (59.9%) had at least one severely bothersome symptom. In multiple regression, older children were significantly more likely to have at least one severely bothersome symptom (15-18 and 11-14 years vs. 8-10 years; P = 0.008) and to have higher total SSPedi scores (P = 0.0003). Those with relapsed disease were more likely to have at least one severely bothersome symptom (odds ratio 2.1, 95% confidence interval 1.1-4.3; P = 0.037) and HSCT recipients were more likely to have higher symptom scores (beta = 3.48, standard error = 1.6; P = 0.030). Almost all children receiving cancer therapies experience bothersome symptoms and 60% have at least one severely bothersome symptom. Older children experienced more severely bothersome symptoms and higher symptom scores. Future studies should follow children longitudinally to better understand the symptom trajectory and should institute interventions to manage symptoms. PMID- 29573198 TI - Formation of stromatolite lamina at the interface of oxygenic-anoxygenic photosynthesis. AB - In modern stromatolites, mineralization results from a complex interplay between microbial metabolisms, the organic matrix, and environmental parameters. Here, we combined biogeochemical, mineralogical, and microscopic analyses with measurements of metabolic activity to characterize the mineralization processes and products in an emergent (<18 months) hypersaline microbial mat. While the nucleation of Mg silicates is ubiquitous in the mat, the initial formation of a Ca-Mg carbonate lamina depends on (i) the creation of a high-pH interface combined with a major change in properties of the exopolymeric substances at the interface of the oxygenic and anoxygenic photoautotrophic layers and (ii) the synergy between two major players of sulfur cycle, purple sulfur bacteria, and sulfate-reducing bacteria. The repetition of this process over time combined with upward growth of the mat is a possible pathway leading to the formation of a stromatolite. PMID- 29573199 TI - NOTCH1 mutation and its prognostic significance in Chinese chronic lymphocytic leukemia: a retrospective study of 317 cases. AB - The proto-oncogene NOTCH1 is frequently mutated in around 10% of patients with chronic lymphocytic leukemia (CLL). This study analyzed NOTCH1 mutation status of 317 Chinese patients with CLL by Sanger sequencing. The frequencies of NOTCH1 mutation in the PEST (proline (P), glutamic acid (E), serine (S), threonine (T) rich protein sequence) domain and the 3' untranslated regions (UTR) were 8.2% and 0.9%, with the most frequent mutation being c.7541_7542delCT and c.*371A>G, respectively. Clinical and biological associations were determined including NOTCH1 mutations with advanced stage (Binet stage, P = 0.010), unmutated immunoglobulin heavy-chain variable region (IGHV) gene (P < 0.001) and trisomy 12 (+12) (P = 0.014). NOTCH1-mutated patients had lower CD20 expression intensity than NOTCH1-unmutated patients (P = 0.029). In addition, NOTCH1-mutated patients had shorter overall survival (OS) (P = 0.002) and treatment-free survival (TFS) (P = 0.002) than NOTCH1-unmutated patients, especially for patients with NOTCH1 c.7541_7542delCT and/or c.*371A>G mutations. Patients with both mutated NOTCH1 and unmutated IGHV had shorter OS (P < 0.001) and TFS (P < 0.001) than those with unmutated NOTCH1 or mutated IGHV. These data provide a comprehensive view of the clinical relevance and prognostic impact of NOTCH1 mutations on Chinese patients with CLL. PMID- 29573200 TI - Anti-tumor effects of a nonsteroidal anti-inflammatory drug zaltoprofen on chondrosarcoma via activating peroxisome proliferator-activated receptor gamma and suppressing matrix metalloproteinase-2 expression. AB - Surgical resection is the only treatment for chondrosarcomas, because of their resistance to chemotherapy and radiotherapy; therefore, additional strategies are crucial to treat chondrosarcomas. Peroxisome proliferator-activated receptor gamma (PPARgamma) is a ligand-activated transcription factor, which has been reported as a possible therapeutic target in certain malignancies including chondrosarcomas. In this study, we demonstrated that a nonsteroidal anti inflammatory drug, zaltoprofen, could induce PPARgamma activation and elicit anti tumor effects in chondrosarcoma cells. Zaltoprofen was found to induce expressions of PPARgamma mRNA and protein in human chondrosarcoma SW1353 and OUMS27 cells, and induce PPARgamma-responsible promoter reporter activities. Inhibitory effects of zaltoprofen were observed on cell viability, proliferation, migration, and invasion, and the activity of matrix metalloproteinase-2 (MMP2); these effects were dependent on PPARgamma activation and evidenced by silencing PPARgamma. Moreover, we showed a case of a patient with cervical chondrosarcoma (grade 2), who was treated with zaltoprofen and has been free from disease progression for more than 2 years. Histopathological findings revealed enhanced expression of PPARgamma and reduced expression of MMP2 after administration of zaltoprofen. These findings demonstrate that zaltoprofen could be a promising drug against the malignant phenotypes in chondrosarcomas via activation of PPARgamma and inhibition of MMP2 activity. PMID- 29573201 TI - Intake of bean fiber, beans, and grains and reduced risk of hormone receptor negative breast cancer: the San Francisco Bay Area Breast Cancer Study. AB - High dietary fiber intake has been associated with reduced breast cancer risk, but few studies considered tumor subtypes defined by estrogen receptor (ER) and progesterone receptor (PR) status or included racial/ethnic minority populations who vary in their fiber intake. We analyzed food frequency data from a population based case-control study, including 2135 breast cancer cases (1070 Hispanics, 493 African Americans, and 572 non-Hispanic Whites (NHWs)) and 2571 controls (1391 Hispanics, 557 African Americans, and 623 NHWs). Odds ratios (OR) and 95% confidence intervals (CI) for breast cancer associated with fiber intake were calculated using unconditional logistic regression. Breast cancer risk associated with high intake (high vs. low quartile) of bean fiber (p-trend = 0.01), total beans (p-trend = 0.03), or total grains (p-trend = 0.05) was reduced by 20%. Inverse associations were strongest for ER-PR- breast cancer, with risk reductions associated with high intake ranging from 28 to 36%. For bean fiber, risk was reduced among foreign-born Hispanics only, who had the highest fiber intake, whereas for grain intake, inverse associations were found among NHWs only. There was no evidence of association with fiber intake from vegetables and fruits or total intake of vegetables and fruits. A high dietary intake of bean fiber and fiber-rich foods such as beans and grains may lower the risk of ER-PR- breast cancer, an aggressive breast cancer subtype for which few risk factors have been identified. PMID- 29573203 TI - Cruciferous Vegetables and Risk of Cancers of the Gastrointestinal Tract. AB - Cancers of the oropharyngeal tissues, oesophagus, stomach, and colorectum are amongst the most common causes of death from cancer throughout the world. Higher consumption of fruits and vegetables is thought to be protective, and cruciferous vegetables are of particular interest because of their unique role as a source of biologically active glucosinolate breakdown products. A literature review of primary studies and meta-analyses indicates that higher consumption of cruciferous vegetables probably reduces the risk of colorectal and gastric cancers by approximately 8% and 19%, respectively. Some studies support the hypothesis that the protective effect against colorectal cancer is modified by genetic polymorphisms of genes regulating the expression of enzymes of the glutathione S-transferase family, but due to contradictory findings the evidence is currently inconclusive. Despite these promising findings, future epidemiological research on the protective effects of cruciferous plants will depend critically upon accurate measurement of dietary exposure, both to the vegetables themselves, and to their active constituents. The development of sensitive chemical assays has facilitated the measurement of urinary excretion of isothiocyanate metabolites as an objective biomarker of intake, but sampling strategies need to be optimized in order to assess long-term exposures at the population level. PMID- 29573202 TI - Localization and dynamics of Wolbachia infection in Asian citrus psyllid Diaphorina citri, the insect vector of the causal pathogens of Huanglongbing. AB - Wolbachia is a group of intracellular bacteria that infect a wide range of arthropods including the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. This insect is the vector of Candidatus Liberibacter asiaticus (CLas), the causal pathogen of Huanglongbing or citrus greening disease. Here, we investigated the localization pattern and infection dynamics of Wolbachia in different developmental stages of ACP. Results revealed that all developmental stages of ACP including egg, 1st-5th instar nymphs, and adults of both gender were infected with Wolbachia. FISH visualization of an ACP egg showed that Wolbachia moved from the egg stalk of newly laid eggs to a randomly distributed pattern throughout the egg prior to hatching. The infection rate varied between nymphal instars. The titers of Wolbachia in fourth and fifth instar nymphs were significantly higher than those in the first and second instar nymphs. Wolbachia were scattered in all nymphal stages, but with highest intensity in the U-shaped bacteriome located in the abdomen of the nymph. Wolbachia was confined to two symmetrical organizations in the abdomen of newly emerged female and male adults. The potential mechanisms of Wolbachia infection dynamics are discussed. PMID- 29573204 TI - Intermediate filament protein evolution and protists. AB - Metazoans evolved from a single protist lineage. While all eukaryotes share a conserved actin and tubulin-based cytoskeleton, it is commonly perceived that intermediate filaments (IFs), including lamin, vimentin or keratin among many others, are restricted to metazoans. Actin and tubulin proteins are conserved enough to be detectable across all eukaryotic genomes using standard phylogenetic methods, but IF proteins, in contrast, are notoriously difficult to identify by such means. Since the 1950s, dozens of cytoskeletal proteins in protists have been identified that seemingly do not belong to any of the IF families described for metazoans, yet, from a structural and functional perspective fit criteria that define metazoan IF proteins. Here, we briefly review IF protein discovery in metazoans and the implications this had for the definition of this protein family. We argue that the many cytoskeletal and filament-forming proteins of protists should be incorporated into a more comprehensive picture of IF evolution by aligning it with the recent identification of lamins across the phylogenetic diversity of eukaryotic supergroups. This then brings forth the question of how the diversity of IF proteins has unfolded. The evolution of IF proteins likely represents an example of convergent evolution, which, in combination with the speed with which these cytoskeletal proteins are evolving, generated their current diversity. IF proteins did not first emerge in metazoa, but in protists. Only the emergence of cytosolic IF proteins that appear to stem from a nuclear lamin is unique to animals and coincided with the emergence of true animal multicellularity. PMID- 29573205 TI - Plasma miRNA can detect colorectal cancer, but how early? AB - Colorectal cancer (CRC) is a major cause of deaths worldwide but has a good prognosis if detected early. The need for efficient, preferable non- or minimally invasive, inexpensive screening tools is therefore critical. We analyzed 12 miRNAs in pre- and postdiagnostic plasma samples to evaluate their potential as CRC screening markers. We used a unique study design with two overlapping cohorts, allowing analysis of pre- and postdiagnostic samples from 58 patients with CRC and matched healthy controls. Plasma concentrations of miR-15b, -16, 18a, -19a, 21, -22, -25, -26a, -29c, -142-5p, -150, and -192 were measured by semi-quantitative real-time PCR. Concentrations of miR-18a, -21, -22, and -25 in plasma from patients with CRC were significantly altered compared to healthy controls. Combined as a multimarker panel, they detected CRC with an AUC of 0.93. Furthermore, levels of these three miRNAs also showed different levels in the prediagnostic case samples close to diagnosis. Only miR-21-levels were elevated several years before diagnosis. Plasma levels of miR-18a, -21, -22, and -25 show promise as screening biomarkers for CRC. However, based on our unique analysis of prediagnostic and postdiagnostic samples from the same patients, we conclude that circulating miRNAs elevated at diagnosis may not automatically be suitable for CRC screening, if the increase occurs too close to clinical diagnosis. PMID- 29573206 TI - Identification of transcriptome signature for predicting clinical response to bevacizumab in recurrent glioblastoma. AB - Glioblastomas are among the most fatal brain tumors. Although no effective treatment option is available for recurrent glioblastomas (GBMs), a subset of patients evidently derived clinical benefit from bevacizumab, a monoclonal antibody against vascular endothelial growth factor. We retrospectively reviewed patients with recurrent GBM who received bevacizumab to identify biomarkers for predicting clinical response to bevacizumab. Following defined criteria, the patients were categorized into two clinical response groups, and their genetic and transcriptomic results were compared. Angiogenesis-related gene sets were upregulated in both responders and nonresponders, whereas genes for each corresponding angiogenesis pathway were distinct from one another. Two gene sets were made, namely, the nonresponder angiogenesis gene set (NAG) and responder angiogenesis gene set (RAG), and then implemented in independent GBM cohort to validate our dataset. A similar association between the corresponding gene set and survival was observed. In NAG, COL4A2 was associated with a poor clinical outcome in bevacizumab-treated patients. This study demonstrates that angiogenesis-associated gene sets are composed of distinct subsets with diverse biological roles and they represent different clinical responses to anti angiogenic therapy. Enrichment of a distinct angiogenesis pathway may serve as a biomarker to predict patients who will derive a clinical benefit from bevacizumab. PMID- 29573207 TI - An open-label, dose-ranging study of Rolontis, a novel long-acting myeloid growth factor, in breast cancer. AB - This randomized, open-label, active-controlled study investigated the safety and efficacy of three doses of Rolontis (eflapegrastim), a novel, long-acting myeloid growth factor, versus pegfilgrastim in breast cancer patients being treated with docetaxel and cyclophosphamide (TC). The primary efficacy endpoint was duration of severe neutropenia (DSN) during the first cycle of treatment. Patients who were candidates for adjuvant/neoadjuvant TC chemotherapy were eligible for participation. TC was administered on Day 1, followed by 45, 135, or 270 MUg/kg Rolontis or 6 mg pegfilgrastim on Day 2. Complete blood counts were monitored daily when the absolute neutrophil count (ANC) fell to <1.5 * 109 /L. Up to four cycles of TC were investigated. The difference in DSN (time from ANC <0.5 * 109 /L to ANC recovery >=2.0 * 109 /L) between the Rolontis and pegfilgrastim groups was -0.28 days (confidence interval [CI]: -0.56, -0.06) at 270 MUg/kg, 0.14 days (CI: -0.28, 0.64) at 135 MUg/kg, and 0.72 days (CI: 0.19, 1.27) at 45 MUg/kg. Noninferiority to pegfilgrastim was demonstrated at 135 MUg/kg (P = 0.002) and 270 MUg/kg (P < .001), with superiority demonstrated at 270 MUg/kg (0.03 days; P = 0.023). The most common treatment-related adverse events (AEs) were bone pain, myalgia, arthralgia, back pain, and elevated white blood cell counts, with similar incidences across groups. All doses of Rolontis were well tolerated, and no new or significant treatment-related toxicities were observed. In Cycle 1, Rolontis demonstrated noninferiority at the 135 MUg/kg dose and statistical superiority in DSN at the 270 MUg/kg dose when compared to pegfilgrastim. PMID- 29573208 TI - Correlating colorectal cancer risk with field carcinogenesis progression using partial wave spectroscopic microscopy. AB - Prior to the development of a localized cancerous tumor, diffuse molecular, and structural alterations occur throughout an organ due to genetic, environmental, and lifestyle factors. This process is known as field carcinogenesis. In this study, we used partial wave spectroscopic (PWS) microscopy to explore the progression of field carcinogenesis by measuring samples collected from 190 patients with a range of colonic history (no history, low-risk history, and high risk history) and current colon health (healthy, nondiminutive adenomas (NDA; >=5 mm and <10 mm), and advanced adenoma [AA; >=10 mm, HGD, or >25% villous features]). The low-risk history groups include patients with a history of NDA. The high-risk history groups include patients with either a history of AA or colorectal cancer (CRC). PWS is a nanoscale-sensitive imaging technique which measures the organization of intracellular structure. Previous studies have shown that PWS is sensitive to changes in the higher-order (20-200 nm) chromatin topology that occur due to field carcinogenesis within histologically normal cells. The results of this study show that these nanoscale structural alterations are correlated with a patient's colonic history, which suggests that PWS can detect altered field carcinogenic signatures even in patients with negative colonoscopies. Furthermore, we developed a model to calculate the 5-year risk of developing CRC for each patient group. We found that our data fit this model remarkably well (R2 = 0.946). This correlation suggests that PWS could potentially be used to monitor CRC progression less invasively and in patients without adenomas, which opens PWS to many potential cancer care applications. PMID- 29573209 TI - Regulatory role of the RstB-RstA system in adhesion, biofilm production, motility, and hemolysis. AB - For infection, initial invasion of the host is of great importance, with adhesion playing a critical role. We previously demonstrated rstA and rstB are remarkably downregulated in Vibrio alginolyticus cultured under heavy metal and acidic stresses, with impaired adhesion, suggesting that rstA and rstB might be involved in adhesion regulation. The present study showed that rstA and rstB silencing resulted in impaired adhesion, biofilm production, motility, hemolysis, and virulence. Meanwhile, changes of temperature, starvation, and pH remarkably affected rstA and rstB expression. These findings indicated that (1) rstA and rstB are critical regulators of adhesion in V. alginolyticus; (2) rstA and rstB have remarkable effects on biofilm production, motility, hemolysis, and virulence in V. alginolyticus; (3) rstA and rstB modulate adhesion in response to environmental changes of temperature, pH, and starvation. PMID- 29573210 TI - Human papillomavirus and survival of patients per histological subsite of tonsillar squamous cell carcinoma. AB - Current data advocate that oropharyngeal squamous cell carcinoma (OPSCC) should be divided into subsites when evaluating the presence of human papillomavirus (HPV) and prognosis. More specifically, tonsillar squamous cell carcinoma (TSCC) and base of tongue squamous cell carcinoma (BOTSCC) have much higher HPV prevalence compared to other OPSCC. Moreover, patients with HPV positive (HPV+) TSCC and BOTSCC have a better prognosis as compared to patients with HPV negative (HPV-) corresponding tumors, while the prognostic role of HPV in other OPSCC is unclear. Furthermore, in a recent report from Denmark, TSCC was further subclassified into specified TSCC (STSCC) and nonspecified TSCC (NSTSCC), with HPV significantly more prevalent in STSCC. In this study, the histopathological influence of HPV prevalence and survival in TSCC was analyzed in a TSCC cohort with known HPV status, of patients diagnosed 1970-2002 in Stockholm. In total, 139 TSCC biopsies with both tumor and adjacent normal tissue were separated into STSCC and NSTSCC. HPV was significantly more commonly found in STSCC than in NSTSCC. Patients with HPV+ STSCC had a better disease-specific and overall survival as compared to patients with HPV+ NSTSCC, but no survival differences were observed in patients with HPV- STSCC and NSTCC. These findings confirm previous reports and suggest that TSCC subsite may also be of relevance for clinical outcome and should be further followed up in future studies. PMID- 29573211 TI - Tannerella forsythia-produced methylglyoxal causes accumulation of advanced glycation endproducts to trigger cytokine secretion in human monocytes. AB - The periodontal pathogen Tannerella forsythia has the unique ability to produce methylglyoxal (MGO), an electrophilic compound which can covalently modify amino acid side chains and generate inflammatory adducts known as advanced glycation endproducts (AGEs). In periodontitis, concentrations of MGO in gingival crevicular fluid are increased and are correlated with the T. forsythia load. However, the source of MGO and the extent to which MGO may contribute to periodontal inflammation has not been fully explored. In this study we identified a functional homolog of the enzyme methylglyoxal synthase (MgsA) involved in the production of MGO in T. forsythia. While wild-type T.forsythia produced a significant amount of MGO in the medium, a mutant lacking this homolog produced little to no MGO. Furthermore, compared with the spent medium of the T. forsythia parental strain, the spent medium of the T. forsythia mgsA-deletion strain induced significantly lower nuclear factor-kappa B activity as well as proinflammogenic and pro-osteoclastogenic cytokines from THP-1 monocytes. The ability of T. forsythia to induce protein glycation endproducts via MGO was confirmed by an electrophoresis-based collagen chain mobility shift assay. Together these data demonstrated that T. forsythia produces MGO, which may contribute to inflammation via the generation of AGEs and thus act as a potential virulence factor of the bacterium. PMID- 29573213 TI - Identification of Clostridium difficile Immunoreactive Spore Proteins of the Epidemic Strain R20291. AB - PURPOSE: Clostridium difficile infections are the leading cause of diarrhea associated with the use of antibiotics. During infection, C. difficile initiates a sporulation cycle leading to the persistence of C. difficile spores in the host and disease dissemination. The development of vaccine and passive immunization therapies against C. difficile has focused on toxins A and B. In this study, an immunoproteome-based approach to identify immunogenic proteins located on the outer layers of C. difficile spores as potential candidates for the development of immunotherapy and/or diagnostic methods against this devastating infection is used. EXPERIMENTAL DESIGN: To identify potential immunogenic proteins on the surface of C. difficile R20291, spore coat/exosporium extracts are separated by 2D electrophoresis (2-DE) and analyzed for reactivity against C. difficile spore specific goat sera. Finally, the selected spots are in-gel digested with chymotrypsin, peptides generated are separated by nanoUPLC followed by MS/MS using Quad-TOF-MS, corroborated by Ultimate 3000RS-nano-UHPLC coupled to Q Exactive-Plus-Orbitrap MS. RESULTS: The analysis identify five immunoreactive proteins: spore coat proteins CotE, CotA, and CotCB; exosporium protein CdeC; and a cytosolic methyltransferase. CONCLUSION: This data provides a list of spore surface protein candidates as antigens for vaccine development against C. difficile infections. PMID- 29573212 TI - Medication use in infants admitted with bronchiolitis. AB - BACKGROUND: There are no medications known that improve the outcome of infants with bronchiolitis. Studies have shown the management of bronchiolitis to be varied. OBJECTIVES: To describe medication use at the seven study hospitals from a recent multi-centre randomised controlled trial on hydration in bronchiolitis (comparative rehydration in bronchiolitis [CRIB]). METHODS: A retrospective analysis of extant data of infants between 2 months (corrected for prematurity) and 12 months of age admitted with bronchiolitis identified through the CRIB trial. CRIB study records, medical records, pathology and radiology databases were used to collect data using a standardised form and entered in a single site database. Medications investigated included salbutamol, adrenaline, steroids, ipratropium bromide, normal saline, hypertonic saline, steroids and antibiotics. RESULTS: There were 3456 infants available for analysis, of which 42.0% received at least one medication during hospitalisation. Medication use varied by site between 27.0 and 48.7%. The most frequently used medication was salbutamol (25.5%). Medication use in general, and salbutamol use in particular, increased by 8.2 and 9.3%, respectively, per month after 4 months of age; from 22.9 and 3.6% at 4 months to 81.4 and 68.8% at 11 months. In infants admitted to the intensive care unit (ICU) compared with those not admitted to ICU 81.6 and 39.5%, respectively, received medication at one point during the hospital stay. CONCLUSIONS: Medication was used for infants with bronchiolitis frequently and variably in Australia and New Zealand. Medication use increased with age. Better strategies for translating evidence into practice are needed. PMID- 29573215 TI - Longitudinal medical resources and costs among type 2 diabetes patients participating in the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS). AB - AIMS: TECOS, a cardiovascular safety trial (ClinicalTrials.gov identifier: NCT00790205) involving 14 671 patients with type 2 diabetes and cardiovascular disease, demonstrated that sitagliptin was non-inferior to placebo for the primary composite cardiovascular outcome when added to best usual care. This study tested hypotheses that medical resource use and costs differed between these 2 treatment strategies. MATERIALS AND METHODS: Information concerning medical resource use was collected on case report forms throughout the trial and was valued using US costs for: Medicare payments for hospitalizations, medical procedures and outpatient visits, and wholesale acquisition costs (WAC) for diabetes-related medications. Hierarchical generalized linear models were used to compare resource use and US costs, accounting for variable intercountry practice patterns. Sensitivity analyses included resource valuation using English costs for a UK perspective. RESULTS: There were no significant differences in hospitalizations, inpatient days, medical procedures, or outpatient visits during follow-up (mean and median 3.0 years in both groups). Hospitalization rates appeared to diverge after 2 years, with lower rates among sitagliptin-treated vs placebo patients after 2.5 years (relative rate, 0.90 [95% CI, 0.83-0.97]; P = .01). Mean medical costs, exclusive of study medication, were 11 937 USD in the sitagliptin arm and 12 409 USD in the placebo arm (P = .06). Mean sitagliptin costs based on undiscounted WAC were 9978 USD per patient. Differential UK total costs including study drug costs were smaller (911 GBP), primarily because of lower mean costs for sitagliptin (1072 GBP). CONCLUSIONS: Lower hospitalization rates across time with sitagliptin slightly offset sitagliptin treatment costs over 3 years in type 2 diabetes patients at high risk for cardiovascular events. PMID- 29573214 TI - Re-irradiation of recurrent gliomas: pooled analysis and validation of an established prognostic score-report of the Radiation Oncology Group (ROG) of the German Cancer Consortium (DKTK). AB - The heterogeneity of high-grade glioma recurrences remains an ongoing challenge for the interdisciplinary neurooncology team. Response to re-irradiation (re-RT) is heterogeneous, and survival data depend on prognostic factors such as tumor volume, primary histology, age, the possibility of reresection, or time between primary diagnosis and initial RT and re-RT. In the present pooled analysis, we gathered data from radiooncology centers of the DKTK Consortium and used it to validate the established prognostic score by Combs et al. and its modification by Kessel et al. Data consisted of a large independent, multicenter cohort of 565 high-grade glioma patients treated with re-RT from 1997 to 2016 and a median dose of 36 Gy. Primary RT was between 1986 and 2015 with a median dose of 60 Gy. Median age was 54 years; median follow-up was 7.1 months. Median OS after re-RT was 7.5, 9.5, and 13.8 months for WHO IV, III, and I/II gliomas, respectively. All six prognostic factors were tested for their significance on OS. Aside from the time from primary RT to re-RT (P = 0.074) and the reresection status (P = 0.101), all factors (primary histology, age, KPS, and tumor volume) were significant. Both the original and new score showed a highly significant influence on survival with P < 0.001. Both prognostic scores successfully predict survival after re-RT and can easily be applied in the routine clinical workflow. Now, further prognostic features need to be found to even improve treatment decisions regarding neurooncological interventions for recurrent glioma patients. PMID- 29573216 TI - Glucose impairments and insulin resistance in prostate cancer: the role of obesity, nutrition and exercise. AB - BACKGROUND: Hyperinsulinemia, obesity and related metabolic diseases are associated with prostate cancer development. Prostate cancer patients undergoing androgen deprivation therapy (ADT) are at increased risk for metabolic syndrome, cardiovascular disease and diabetes, while pre-existing metabolic conditions may be exacerbated. PURPOSE: An integrative approach is used to describe the interactions between insulin, glucose metabolism, obesity and prostate cancer. The potential role of nutrition and exercise will also be examined. FINDINGS: Hyperinsulinemia is associated with prostate cancer development, progression and aggressiveness. Prostate cancer patients who undergo ADT are at risk of diabetes in survivorship. It is unclear whether this is a direct result of treatment or related to pre-existing metabolic features (e.g. hyperinsulinemia and obesity). Obesity and metabolic syndrome are also associated with prostate cancer development and poorer outcomes for cancer survivors, which may be driven by hyperinsulinemia, pro-inflammation, hyperleptinemia and/or hypoadiponectinemia. CONCLUSIONS: Independently evaluating changes in glucose metabolism near the time of prostate cancer diagnosis and during long-term ADT treatment is important to distinguish their unique contributions to the development of metabolic disturbances. Integrative approaches, including metabolic, clinical and body composition measures, are needed to understand the role of adiposity and insulin resistance in prostate cancer and to develop effective nutrition and exercise interventions to improve secondary diseases in survivorship. PMID- 29573217 TI - The benefit and risk of nivolumab in non-small-cell lung cancer: a single-arm meta-analysis of noncomparative clinical studies and randomized controlled trials. AB - Nivolumab is a programmed cell death 1 (PD-1) receptor inhibitor antibody that enhances immune system antitumor activity. Although it is used for treating advanced non-small-cell lung cancer (NSCLC), its actual efficacy has not been determined. We searched PubMed, the Cochrane Library, Embase, MEDLINE, and Web of Science for related noncomparative clinical studies and randomized controlled trials (RCTs) to assess nivolumab benefit and risk in NSCLC. The main outcomes were objective response rate (ORR), 1-year overall survival rate (1-yOS rate), and progression-free survival rate at 24 weeks (PFS at 24 weeks rate), any-grade adverse effects rate (any-grade AEs%), and grade 3-4 AE rate (grade 3-4 AEs%). Relative risk (RR) was used to compare ORR in patients with positive and negative programmed cell death ligand 1 (PD-L1) expression. Random-effects models were used to determine pooled effect size and two-sided 95% confidence intervals (95% CI). We included 20 studies (17 noncomparative open-label cohort studies, three RCTs) involving 3404 patients in our meta-analysis. The modified nivolumab ORR was 18% (95% CI: 15-20%), the 1-yOS rate was 45% (95% CI: 40-50%), PFS at 24 weeks rate was 42% (95% CI: 37-48%), any-grade AEs% was 61% (95% CI: 50-73%), and grade 3-4 AEs% was 12% (95% CI: 9-16%). PD-L1 expression was related with the nivolumab ORR. Nivolumab potentially causes ongoing response, long-term PFS, and reduced treatment-related AEs. PD-L1 expression predicts the outcome of nivolumab immunotherapy. More high-quality and well-designed RCTs with large sample sizes are warranted to prove our findings. PMID- 29573218 TI - Understanding environmental contributions to autism: Causal concepts and the state of science. AB - : The complexity of neurodevelopment, the rapidity of early neurogenesis, and over 100 years of research identifying environmental influences on neurodevelopment serve as backdrop to understanding factors that influence risk and severity of autism spectrum disorder (ASD). This Keynote Lecture, delivered at the May 2016 annual meeting of the International Society for Autism Research, describes concepts of causation, outlines the trajectory of research on nongenetic factors beginning in the 1960s, and briefly reviews the current state of this science. Causal concepts are introduced, including root causes; pitfalls in interpreting time trends as clues to etiologic factors; susceptible time windows for exposure; and implications of a multi-factorial model of ASD. An historical background presents early research into the origins of ASD. The epidemiologic literature from the last fifteen years is briefly but critically reviewed for potential roles of, for example, air pollution, pesticides, plastics, prenatal vitamins, lifestyle and family factors, and maternal obstetric and metabolic conditions during her pregnancy. Three examples from the case control CHildhood Autism Risks from Genes and the Environment Study are probed to illustrate methodological approaches to central challenges in observational studies: capturing environmental exposure; causal inference when a randomized controlled clinical trial is either unethical or infeasible; and the integration of genetic, epigenetic, and environmental influences on development. We conclude with reflections on future directions, including exposomics, new technologies, the microbiome, gene-by-environment interaction in the era of -omics, and epigenetics as the interface of those two. As the environment is malleable, this research advances the goal of a productive and fulfilling life for all children, teen-agers and adults. Autism Res 2018, 11: 554-586. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This Keynote Lecture, delivered at the 2016 meeting of the International Society for Autism Research, discusses evidence from human epidemiologic studies of prenatal factors contributing to autism, such as pesticides, maternal nutrition and her health. There is no single cause for autism. Examples highlight the features of a high quality epidemiology study, and what comprises a compelling case for causation. Emergent research directions hold promise for identifying potential interventions to reduce disabilities, enhance giftedness, and improve lives of those with ASD. PMID- 29573219 TI - Predicting loneliness with polygenic scores of social, psychological and psychiatric traits. AB - Loneliness is a heritable trait that accompanies multiple disorders. The association between loneliness and mental health indices may partly be due to inherited biological factors. We constructed polygenic scores for 27 traits related to behavior, cognition and mental health and tested their prediction for self-reported loneliness in a population-based sample of 8798 Dutch individuals. Polygenic scores for major depressive disorder (MDD), schizophrenia and bipolar disorder were significantly associated with loneliness. Of the Big Five personality dimensions, polygenic scores for neuroticism and conscientiousness also significantly predicted loneliness, as did the polygenic scores for subjective well-being, tiredness and self-rated health. When including all polygenic scores simultaneously into one model, only 2 major depression polygenic scores remained as significant predictors of loneliness. When controlling only for these 2 MDD polygenic scores, only neuroticism and schizophrenia remain significant. The total variation explained by all polygenic scores collectively was 1.7%. The association between the propensity to feel lonely and the susceptibility to psychiatric disorders thus pointed to a shared genetic etiology. The predictive power of polygenic scores will increase as the power of the genome-wide association studies on which they are based increases and may lead to clinically useful polygenic scores that can inform on the genetic predisposition to loneliness and mental health. PMID- 29573220 TI - Depleted iron stores are associated with inspiratory muscle weakness independently of skeletal muscle mass in men with systolic chronic heart failure. AB - BACKGROUND: Skeletal and respiratory muscle dysfunction constitutes an important pathophysiological feature of heart failure (HF). We assessed the relationships between respiratory muscle function, skeletal muscle mass, and physical fitness in men with HF with reduced left ventricular ejection fraction (HFrEF), and investigated the hypothesis of whether iron deficiency (ID) contributes to respiratory muscle dysfunction in these patients. METHODS: We examined 53 male outpatients with stable HFrEF without asthma or chronic obstructive pulmonary disease (age: 64 +/- 10 years; New York Heart Association [NYHA] class I/II/III: 36/51/13%; ischaemic aetiology: 83%; all with left ventricular ejection fraction <=40%) and 10 middle-aged healthy men (control group). We analysed respiratory muscle function (maximal inspiratory and expiratory pressure at the mouth [MIP and MEP, respectively]), appendicular lean mass/body mass index (ALM/BMI; ALM was measured using dual-energy X-ray absorptiometry), physical fitness (components of Functional Fitness Test for Older Adults), and iron status. RESULTS: MIP, MEP, and ALM/BMI (but not MIP adjusted for ALM/BMI) were lower in men with HFrEF vs. healthy men. MIP, MEP, and MIP adjusted for ALM/BMI (but not ALM/BMI) were lower in men with HFrEF with vs. without ID. In a multivariable linear regression model lower serum ferritin (but not transferrin saturation) was associated with lower MIP independently of ALM/BMI, left ventricular ejection fraction, N-terminal pro B-type natriuretic peptide (NT-proBNP), and haemoglobin concentration. In multivariable linear regression models, lower MIP was associated with worse results in Functional Fitness Test when adjusted for ALM/BMI or relevant clinical variables (NYHA class, estimated glomerular filtration rate, NT-proBNP, and haemoglobin concentration). CONCLUSIONS: In men with HFrEF, low ferritin reflecting depleted iron stores is associated with inspiratory muscle weakness independently of skeletal muscle mass. Inspiratory muscle dysfunction correlates with worse physical fitness independently of either skeletal muscle mass or disease severity. PMID- 29573221 TI - Glycemic extremes are related to cognitive dysfunction in children with type 1 diabetes: A meta-analysis. AB - AIMS/INTRODUCTION: To examine the magnitude and pattern of cognitive dysfunction in children with type 1 diabetes, and the possible effects associated with other disease variables, such as early onset diabetes, severe hypoglycemia and hyperglycemia. MATERIALS AND METHODS: We carried out a meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We searched MedLine, Embase and PsycINFO to identify studies on cognitive function in children with type 1 diabetes that were published up until 30 September 2016. Effect sizes understood as the standardized mean differences between groups with diabetes and control groups (i.e., Hedges' g) were calculated to quantify the extent of cognitive dysfunction in those groups consisting of children with diabetes. RESULTS: A total of 19 studies met our inclusion criteria, comprising 1,355 participants with type 1 diabetes and 696 controls. Compared with non diabetic controls, children with type 1 diabetes showed a significantly poorer cognitive performance overall (g = -0.46), as well as specific deficits in full scale intelligence (g = -1.06), attention (g = -0.60) and psychomotor speed (g = 0.46). Glycemic extremes were associated with poorer overall cognition (g = 0.18), as well as slightly lower performance in memory (g = -0.27). CONCLUSIONS: We found that type 1 diabetes was associated with cognitive dysfunction characterized by a lowered intelligence, diminished attention and a slowing of psychomotor speed. Glycemic extremes, which are described as a period of high glucose levels and severe hypoglycemia, were related to cognitive dysfunction in children with type 1 diabetes. PMID- 29573223 TI - Mycobiota of maize seeds revealed by rDNA-ITS sequence analysis of samples with varying storage times. AB - Fungi are an integral component of the plant microbiome. However, the composition and variation in the fungal communities (mycobiota) associated with seeds are poorly understood. In this study, we investigated the mycobiota of 11 maize seed samples with storage times ranging from 6 months to 12 years. Mycobiota were characterized by a culture-based approach, and fungal species were identified through rDNA-ITS sequence analyses. From a total of 169 pure fungal isolates obtained from both the seed surface and internal tissues, we identified 16 distinct species (belonging to 10 genera) associated with maize seeds, all but one of which were ascomycetes. Among these species, seven were exclusively isolated from internal tissues, two species were isolated only from the seed surface, and another six species were isolated from both the surface and internal tissues. Aspergillus niger was consistently found under all storage conditions and dominated fungal communities with a relative abundance of 36%-100%. Species of Fusarium (9%-40%) and Penicillium (9%-20%) were also frequently isolated, but other species appeared sporadically and were isolated from fewer than three seed stocks. According to our results, while the overall incidence of fungal infection generally declined with storage time, there was no consistent association between seed storage time and fungal species richness or relative abundance; furthermore, the composition of the mycobiota associated with maize seeds was highly variable among the samples. The detection of the four major mycotoxigenic fungal genera, specifically Aspergillus, Fusarium, Penicillium, and Alternaria, was alarming, and the isolation of a potential controlling agent as well as information about their temporal occurrence will contribute to the management of mycotoxins in the future. PMID- 29573224 TI - Mediterranean Diet, Glucose Homeostasis, and Inflammasome Genetic Variants: The CORDIOPREV Study. AB - SCOPE: Insulin resistance (IR) and chronic low-grade inflammation are hallmarks of type 2 diabetes mellitus (T2DM). The "NOD-like receptor pyrin domain containing-3" (NLRP3) inflammasome component of innate immunity is a metabolic stress sensor modulated by dietary and genetics factors. The aim of this study was to evaluate the effects of the consumption of two diets for 3 years, Mediterranean (Med) and low fat, on glucose homeostasis in the 1002 coronary heart disease patients of the CORDIOPREV study, according to a genetic variant of NLRP3 inflammasome. METHODS AND RESULTS: The study was conducted in the framework of the CORDIOPREV study, a randomized dietary intervention with Med and low-fat diets. Single nucleotide polymorphisms (SNPs) located at inflammasome NLRP3 gene were genotyped by OpenArray platform. Nondiabetic CT+TT carriers of the rs4612666 SNP and AG+AA carriers of the rs10733113 SNP increased insulin sensitivity index (ISI) after 3 years of dietary intervention, whereas no effect was observed in diabetic patients. Further analysis by diet showed that the improvement of the ISI in nondiabetic rs10733113 AG+AA carriers was specific to the consumption of the Med diet. CONCLUSION: Our results show that the benefits associated with a Med diet regarding glucose homeostasis in non-T2DM patients depend on genetic variation in the inflammasome. PMID- 29573222 TI - Concise Review: Altered Versus Unaltered Amniotic Membrane as a Substrate for Limbal Epithelial Cells. AB - Limbal stem cell deficiency (LSCD) can result from a variety of corneal disorders, including chemical and thermal burns, infections, and autoimmune diseases. The symptoms of LSCD may include irritation, epiphora, blepharospasms, photophobia, pain, and decreased vision. There are a number of treatment options, ranging from nonsurgical treatments for mild LSCD to various forms of surgery that involve different cell types cultured on various substrates. Ex vivo expansion of limbal epithelial cells (LEC) involves the culture of LEC harvested either from the patient, a living relative, or a cadaver on a substrate in the laboratory. Following the transfer of the cultured cell sheet onto the cornea of patients suffering from LSCD, a successful outcome can be expected in approximately three out of four patients. The phenotype of the cultured cells has proven to be a key predictor of success. The choice of culture substrate is known to affect the phenotype. Several studies have shown that amniotic membrane (AM) can be used as a substrate for expansion of LEC for subsequent transplantation in the treatment of LSCD. There is currently a debate over whether AM should be denuded (i.e., de-epithelialized) prior to LEC culture, or whether this substrate should remain intact. In addition, crosslinking of the AM has been used to increase the thermal and mechanical stability, optical transparency, and resistance to collagenase digestion of AM. In the present review, we discuss the rationale for using altered versus unaltered AM as a culture substrate for LEC. Stem Cells Translational Medicine 2018;7:415-427. PMID- 29573225 TI - Concise Review: Stem Cell Fate Guided By Bioactive Molecules for Tendon Regeneration. AB - Tendon disorders, which are commonly presented in the clinical setting, disrupt the patients' normal work and life routines, and they damage the careers of athletes. However, there is still no effective treatment for tendon disorders. In the field of tissue engineering, the potential of the therapeutic application of exogenous stem cells to treat tendon pathology has been demonstrated to be promising. With the development of stem cell biology and chemical biology, strategies that use inductive tenogenic factors to program stem cell fate in situ are the most easily and readily translatable to clinical applications. In this review, we focus on bioactive molecules that can potentially induce tenogenesis in adult stem cells, and we summarize the various differentiation factors found in comparative studies. Moreover, we discuss the molecular regulatory mechanisms of tenogenesis, and we examine the various challenges in developing standardized protocols for achieving efficient and reproducible tenogenesis. Finally, we discuss and predict future directions for tendon regeneration. Stem Cells Translational Medicine 2018;7:404-414. PMID- 29573226 TI - Human papillomavirus detection with genotyping by the cobas and Aptima assays: Significant differences in HPV 16 detection? AB - BACKGROUND: The primary high-risk human papillomavirus (hrHPV) assays in the United States are the cobas (Roche) and the Aptima (Hologic). The cobas assay detects hrHPV by DNA analysis while the Aptima detects messenger RNA (mRNA) oncogenic transcripts. As the Aptima assay identifies oncogenic expression, it should have a lower rate of hrHPV and genotype detection. METHODS: The Kaiser Permanente Regional Reference Laboratory in Denver, Colorado changed its hrHPV assay from the cobas to the Aptima assay. The rates of hrHPV detection and genotyping were compared over successive six-month periods. RESULTS: The overall hrHPV detection rates by the two platforms were similar (9.5% versus 9.1%) and not statistically different. For genotyping, the HPV 16 rate by the cobas was 1.6% and by the Aptima it was 1.1%. These differences were statistically different with the Aptima detecting nearly one-third less HPV 16 infections. With the HPV 18 and HPV 18/45, there was a slightly higher detection rate of HPV 18/45 by the Aptima platform (0.5% versus 0.9%) and this was statistically significant. CONCLUSION: While HPV 16 represents a low percentage of hrHPV infections, it was detected significantly less by the Aptima assay compared to the cobas assay. This has been previously reported, although not highlighted. Given the test methodologies, one would expect the Aptima to detect less HPV 16. This difference appears to be mainly due to a significantly increased number of non-oncogenic HPV 16 infections detected by the cobas test as there were no differences in HPV 16 detection rates in the high-grade squamous intraepithelial lesions indicating that the two tests have similar sensitivities for oncogenic HPV 16. PMID- 29573227 TI - Patients' preoperative background causes gastric stasis after laparoscopy assisted pylorus-preserving gastrectomy. AB - INTRODUCTION: Despite technical improvements in laparoscopic gastrectomy, gastric stasis is still a serious problem in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). The aim of this study was to investigate the factors that might cause gastric stasis in LAPPG. METHODS: From April 2004 through November 2012, 85 patients with cT1N0 middle-third gastric cancer who underwent LAPPG at Kitasato University Hospital; these patients were included in the present study. Infra-pyloric vein (IPV)-preserving LAPPG was performed in 41 patients. We compared the rate of gastric stasis in the IPV-preserving and the IPV-non preserving groups, and analyzed the clinicopathological factors that might have caused gastric stasis. RESULTS: We did not demonstrate that preservation of the IPV could prevent gastric stasis in the early and late postoperative periods. Symptoms of gastric stasis were most frequently recognized 1 year after surgery. A significantly higher proportion of preoperative ASA class 2 patients had gastric stasis than did not (80.0% [12/15] vs 48.6% [34/70], P=0.02). Among the ASA class 2 patients, a significantly greater proportion of those with depressed activities of daily living than those with normal activities of daily living had gastric stasis (66.7% [4/6] vs 20.0% [8/40], P = 0.015). CONCLUSIONS: The clinical significance of the IPV preservation in LAPPG could not be demonstrated. LAPPG should be performed for ASA class 1 patients or those with maintained preoperative activities of daily living. PMID- 29573229 TI - Urinary tract blastomycosis diagnosed by urine cytology. AB - Urinary tract blastomycosis is an uncommon manifestation of disseminated Blastomyces infection. Here, we report a 50-year-old male with common variable immunodeficiency who presented with urinary symptoms and a renal mass concerning for a kidney neoplasm. Urine cytology revealed typical broad-based budding yeasts with thick-walled refractile capsules, leading to diagnosis of urinary tract blastomycosis. In this case, urine cultures were negative, and urine cytology was the main method of diagnosis of blastomycosis. Thus, urine cytology represents a rapid and reliable method of diagnosing blastomycosis, which in the current case led to prompt treatment of this potentially life threatening infection. PMID- 29573228 TI - A prospective study of soluble receptor for advanced glycation end products and adipokines in association with pancreatic cancer in postmenopausal women. AB - Advanced glycation end products (AGEs) dysregulate adipokines and induce inflammation by binding to their adipocyte receptor (RAGE). Soluble RAGE (sRAGE) prevents AGEs/RAGE signaling. We performed a nested case-control study of the association between sRAGE, adipokines, and incident pancreatic cancer risk in the prospective Women's Health Initiative Study. We individually matched controls (n = 802) to cases (n = 472) on age, race, and blood draw date. We evaluated serum concentrations of sRAGE, adiponectin, leptin, monocyte chemotactic protein 1 (MCP1), and plasminogen activator inhibitor-1 (PAI1) using immunoassay. We used conditional logistic regression model to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for pancreatic cancer over biomarker quartiles (Q1 Q4). We used principal component analysis to create two composite biomarkers and performed a confirmatory factor analysis to examine the association between composite biomarker scores (CBS) and pancreatic cancer risk. Baseline serum sRAGE concentrations were inversely associated with pancreatic cancer risk (aORQ4 vs. Q1 = 0.70, 95% CI: 0.50-0.99). High MCP1 (aOR Q4 vs. Q1 = 2.55, 95% CI: 1.41 4.61) and the higher CBS including MCP1, PAI1, and leptin (aORQ4 vs. Q1 = 1.82, 95% CI = 1.04-3.18) were also associated with increased pancreatic cancer risk among women with BMI <25 kg/m2 (P values for interaction <0.05). We found an inverse association between prediagnostic sRAGE concentrations and risk of incident pancreatic cancer in postmenopausal women. A proinflammatory CBS was associated with increased risk only in women with normal BMI. MCP1 was not modulated by sRAGE. PMID- 29573230 TI - A case of endocervical minimal deviation adenocarcinoma with varicolored cytopathologic features on Pap smear. AB - We report a case of minimal deviation adenocarcinoma (MDA) of the uterine cervix showing varicolored cytopathologic features on Papanicolaou (Pap) smear, which may indicate features suggestive of lobular endocervical glandular hyperplasia (LEGH)-adenocarcinoma sequence. A 57-year-old woman presented with a profuse amount of watery vaginal discharge. Gynecological examination revealed a cervical mass with involvement of the right parametrium. Conventional Pap smear showed hypercellularity consisting of approximately 4 types of clusters as follows: (1) clusters showing a monolayered honeycomb sheet of endocervical cells with golden yellow mucin and bland nuclei, (2) three-dimensional clusters showing varicolored mucin and irregular nuclear overlapping, (3) irregularly shaped clusters showing distorted chicken-wire-mesh appearance with noticeable protrusions of the nuclei and clear or faint varicolored cytoplasm, and (4) crowded clusters showing scarce mucin and nuclear atypia. The surgically resected uterus revealed LEGH-mimicking lesion with fused papillae and a cribriform pattern in the endocervix and many glands exhibiting gastric differentiation that invaded deeper areas of the stroma with a subtle stromal reaction. Compared with histologic findings, two types of clusters, the crowded cluster with scarce mucin and the cluster with distorted chicken-wire-mesh-type appearance, were considered as adenocarcinoma, and the latter was interpreted as a gastric-type adenocarcinoma. Three-dimensional varicolored type clusters showed atypical features, but insufficient atypical features compared with those of adenocarcinoma. Detection of clusters with varicolored mucin on conventional Pap smear may provide a clue for the early recognition of the malignant potential of LEGH on cytology. The chicken-wire-mesh type clusters may be a characteristic cytologic finding of MDA. PMID- 29573231 TI - Caution with iceberg model for colonoscopy in mind!

PMID- 29573233 TI - Adolescent preferences for weight terminology used by health care providers. AB - BACKGROUND: In light of high rates of obesity and weight stigma in youth, the American Academy of Paediatrics recommends that paediatric health care professionals use appropriate, sensitive and non-stigmatizing language in communication about weight with youth. For these efforts to be effective, there is a need to identify weight-based language preferences among youth with overweight and obesity, as research in this area is scarce. OBJECTIVES: The present study provides a systematic assessment of youth perspectives of weight based language used by providers. METHODS: Adolescents (ages 13-18 years; N = 148) enrolled in a national weight loss camp were surveyed about their preferences for words that health providers use to refer to their body weight. Adolescents completed an online survey and responded to a list of 16 words describing excess body weight, as well as questions assessing demographics, body mass index, and experienced as well as internalized weight stigma. RESULTS: Adolescents assigned low ratings to words like 'fat', 'large', 'obese' and 'extremely obese', indicating that they would not want providers to use these words when discussing their body weight. In contrast, words like 'weight problem', 'BMI' and 'plus size' were rated among the most preferred words for providers to use. Word preferences varied across gender, body mass index and extent of internalized weight stigma. CONCLUSIONS: These findings underscore the importance of acknowledging different word preferences among youth, and to avoid making assumptions about what words youth will feel most comfortable using in discussions about their body weight.

AB - Inherited peripheral neuropathies (IPNs) are a clinically and genetically heterogeneous group of diseases affecting the motor and sensory peripheral nerves. IPNs have benefited from gene discovery and genetic diagnosis using next generation sequencing with over 80 causative genes available for testing. Despite this success, up to 50% of cases remain genetically unsolved. In the absence of protein coding mutations, noncoding DNA or structural variation (SV) mutations are a possible explanation. The most common IPN, Charcot-Marie-Tooth neuropathy type 1A (CMT1A), is caused by a 1.5 Mb duplication causing trisomy of the dosage sensitive gene PMP22. Using genome sequencing, we recently identified two large genomic rearrangements causing IPN subtypes X-linked CMT (CMTX3) and distal hereditary motor neuropathy (DHMN1), thereby expanding the spectrum of SV mutations causing IPN. Understanding how newly discovered SVs can cause IPN may serve as a useful paradigm to examine the role of topologically associated domains (TADs), chromatin interactions, and gene dysregulation in disease. This review will describe the growing role of SV in the pathogenesis of IPN and the importance of considering this type of mutation in Mendelian diseases where protein coding mutations cannot be identified.

AB - : Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and restricted, repetitive patterns of behavior. For more than a decade, genetically-modified, risk factor-induced, as well as naturally occurring rodent models for ASD have been used as the most predominant tools to dissect the molecular and circuitry mechanisms underlying ASD. However, the apparent evolutionary differences in terms of social behavior and brain anatomy between rodents and humans have become an issue of debate regarding the translational value of rodent models for studying ASD. More recently, genome manipulation of non human primates using lentivirus-based gene expression, TALEN and CRISPR/Cas9 mediated gene editing techniques, has been reported. Genetically modified non-human primate models for ASD have been produced and characterized. While the feasibility, value, and exciting opportunities provided by the non human primate models have been clearly demonstrated, many challenges still remain. Here, we review current progress, discuss the remaining challenges, and highlight the key issues in the development of non-human primate models for ASD research and drug development. Autism Res 2018, 11: 686-694. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Over the last two decades, genetically modified rat and mouse models have been used as the most predominant tools to study mechanisms underlying autism spectrum disorder (ASD). However, the apparent evolutionary differences between rodents and humans limit the translational value of rodent models for studying ASD. Recently, several non-human primate models for ASD have been established and characterized. Here, we review current progress, discuss the challenges, and highlight the key issues in the development of non-human primate models for ASD research and drug development. PMID- 29573235 TI - Serum exosomal microRNAs combined with alpha-fetoprotein as diagnostic markers of hepatocellular carcinoma. AB - Exosomal microRNAs have recently been studied as the potential diagnostic marker for various malignancies, including hepatocellular carcinoma (HCC). The aim of this study was to investigate serum exosomal microRNA profiles as HCC diagnostic marker. Transmission electron microscopy and Western blot were used to identify serum exosomes. Deep sequencing was performed to screen differentially expressed microRNAs between HCC (n = 5) and liver cirrhosis (LC, n = 5) groups. Three upregulated and two downregulated microRNAs were selected for qPCR analysis. The levels of selected microRNAs were normalized to Caenorhabditis elegans miR-39 microRNA mimics. Serum exosomal level of miR-122, miR-148a, and miR-1246 was further analyzed and significantly higher in HCC than LC and normal control (NC) groups (P < 0.001), but not different from chronic hepatitis group (P > 0.05). The receiver operating characteristic curve was used to evaluate the diagnostic performance of candidate microRNAs. Area under the curve (AUC) of miR-148a was 0.891 [95% confidence interval (CI), 0.809-0.947] in discriminating HCC from LC, remarkably higher than alpha-fetoprotein (AFP) (AUC: 0.712, 95% CI: 0.607-0.803). Binary logistic regression was adopted to establish the diagnostic model for discriminating HCC from LC. And the combination of miR-122, miR-148a, and AFP increased the AUC to 0.931 (95% CI, 0.857-0.973), which can also be applied for distinguishing early HCC from LC. miR-122 was the best for differentiating HCC from NC (AUC: 0.990, 95% CI, 0.945-1.000). These data suggest that serum exosomal microRNAs signature or their combination with traditional biomarker may be used as a suitable peripheral screening tool for HCC.

AB - AIM: Patients with advanced nonsquamous nonsmall cell lung cancer (NSCLC) who experienced progression with two or more lines chemotherapy have no treatment options that clearly confer a survival benefit. As a novel vascular endothelial growth factor receptor-2 tyrosine kinase inhibitor, apatinib has a certain antitumor effect for various solid tumors. The present study evaluated the efficacy and safety of apatinib in advanced nonsquamous NSCLC as salvage treatment in Chinese real-world practice. METHODS: Twenty-eight patients were enrolled in this observational study from October 2015 to May 2017. Progression free survival (PFS) and overall survival (OS) were graphed by Kaplan-Meier curve and intergroup comparisons were carried out by log-rank test. Objective response rate (ORR), disease control rate (DCR) and adverse effects (AEs) were also evaluated. RESULTS: Seven patients obtained partial response, and 18 obtained stable disease, representing an ORR of 26% and a DCR of 93%. Median PFS and OS were 3 (95% confidence interval [CI] 2.6-3.4) and 7.4 (95% CI 1.3-13.5) months, respectively. The efficacy analysis showed that Eastern Cooperative Oncology Group (ECOG) performance status 0-1 was correlated with prolonged OS and PFS (P < 0.05), and hypertension during apatinib treatment was correlated with prolonged OS (P < 0.05). Cox regression showed that ECOG performance status (P < 0.01) (RR = 0.231) (95% CI 0.083-0.642) and hypertension during apatinib treatment (P = 0.05) were predictive indicators for apatinib treatment. Grade 3-4 AEs with incidences of 10% or greater were hypertension (21%), hand-foot syndrome (14%) and proteinuria (11%) which could be relieved by dose reduction. CONCLUSION: In conclusion, apatinib has a certain therapeutic effect in patients with advanced nonsquamous NSCLC. ECOG performance status and hypertension during apatinib might be predictive indicators for treatment efficacy. PMID- 29573237 TI - Vitamin D administration leads to a shift of the intestinal bacterial composition in Crohn's disease patients, but not in healthy controls. AB - OBJECTIVE: Dysbiosis is a common feature in the pathogenesis of inflammatory bowel diseases (IBD). Environmental factors, such as vitamin D deficiency, seem to play a role in the intestinal inflammation of IBD. The aim of this study was to investigate whether vitamin D administration has an impact on the bacterial composition in Crohn's disease (CD) compared to healthy controls (HC). METHODS: A prospective, longitudinal, controlled interventional analysis was conducted in seven patients with CD in clinical remission and 10 HC to investigate the effect of orally administrated vitamin D on the intestinal bacterial composition using 16S ribosomal RNA gene amplicon sequencing. Clinical parameters were assessed. RESULTS: In contrast to HC, microbial communities of CD patients changed significantly during early vitamin D administration. However, a further increase in vitamin D level was associated with a reversal of this effect and additionally with a decrease in the bacterial richness in the CD microbiome. Specific species with a high abundancy were found during vitamin D administration in CD, but not in HC; the abundancy of Alistipes, Barnesiella, unclassified Porphyromonadaceae (both Actinobacteria), Roseburia, Anaerotruncus, Subdoligranulum and an unclassified Ruminococaceae (all Firmicutes) increased significantly after 1-week vitamin D administration in CD. CONCLUSIONS: Vitamin D has a specific influence on the bacterial communities in CD, but not in HC. Administration of vitamin D may have a positive effect in CD by modulating the intestinal bacterial composition and also by increasing the abundance of potential beneficial bacterial strains. PMID- 29573238 TI - Trabecular Anisotropy in the Primate Mandibular Condyle Is Associated with Dietary Toughness. AB - Past attempts to establish a relationship between mandibular morphology and different dietary categories (e.g., frugivore, folivore, insectivore) have had mixed results, possibly because descriptive dietary categories are too broad and obscure variation within primate diets. Another potential reason is that not all aspects of skeletal architecture, especially trabecular anisotropy, have factored into functional assessments of dietary inputs into jaw form. Recent emphasis on quantifying food mechanical properties (FMPs) has provided an alternative to reliance on dietary categories. We used data on FMPs to test for correlations among dietary toughness and Young's modulus and the trabecular structure of the mandibular condyle, which is loaded during feeding and should reflect differences in masticatory stresses associated with different dietary FMPs. Adult primate mandibles from 11 species were imaged using high-resolution X-ray computed tomography, and trabecular structure was analyzed with BoneJ and Quant3D to assess common three-dimensional trabecular parameters. Results of phylogenetic generalized least squares analysis suggested a positive correlation between the degree of anisotropy (DA) and toughness, and weaker correlations between FMPs and various other trabecular variables. Because the DA contributes to the mechanical properties of bone, these results suggest a functional relationship between dietary toughness and trabecular anisotropy in the mandibular condyle. Such a perspective underscores the need to consider all aspects of skeletal morphology in evaluating the links between diet and jaw biomechanics. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29573239 TI - Thresholds of physical activity associated with obesity by level of sedentary behaviour in children. AB - BACKGROUND: It is unknown whether moderate-to-vigorous physical activity (MVPA) thresholds for obesity should be adapted depending on level of sedentary behaviour in children. OBJECTIVE: The objective of the study is to determine the MVPA thresholds that best discriminate between obese and non-obese children, by level of screen time and total sedentary time in 12 countries. METHODS: This multinational, cross-sectional study included 6522 children 9-11 years of age. MVPA and sedentary time were assessed using waist-worn accelerometry, while screen time was self-reported. Obesity was defined according to the World Health Organization reference data. RESULTS: Receiver operating characteristic curve analyses showed that the best thresholds of MVPA to predict obesity ranged from 53.8 to 73.9 min d-1 in boys and from 41.7 to 58.7 min d-1 in girls, depending on the level of screen time. The MVPA cut-offs to predict obesity ranged from 37.9 to 75.9 min d-1 in boys and from 32.5 to 62.7 min d-1 in girls, depending on the level of sedentary behaviour. The areas under the curve ranged from 0.57 to 0.73 ('fail' to 'fair' accuracy), and most sensitivity and specificity values were below 85%, similar to MVPA alone. Country-specific analyses provided similar findings. CONCLUSIONS: The addition of sedentary behaviour levels to MVPA did not result in a better predictive ability to classify children as obese/non-obese compared with MVPA alone. PMID- 29573240 TI - Liquid biopsy by NGS: differential presence of exons (DPE) in cell-free DNA reveals different patterns in metastatic and nonmetastatic colorectal cancer. AB - Next-generation sequencing (NGS) has been proposed as a suitable tool for liquid biopsy in colorectal cancer (CRC), although most studies to date have focused almost exclusively on sequencing of panels of potential clinically actionable genes. We evaluated the clinical value of whole-exome sequencing (WES) of cell free DNA (cfDNA) circulating in plasma, with the goal of identifying differential clinical profiles in patients with CRC. To this end, we applied an original concept, "differential presence of exons" (DPE). We determined differences in levels of 379 exons in plasma cfDNA and used DPE analysis to cluster and classify patients with disseminated and localized disease. The resultant bioinformatics analysis pipeline allowed us to design a predictive DPE algorithm in a small subset of patients that could not be initially classified based on the selection criteria. This DPE suggests that these nucleic acids could be actively released by both tumor and nontumor cells as a means of intercellular communication and might thus play a role in the process of malignant transformation. DPE is a new technique for the study of plasma cfDNA by WES that might have predictive and prognostic value in patients with CRC. PMID- 29573241 TI - Large buoyant particles dominated by cyanobacterial colonies harbor distinct bacterial communities from small suspended particles and free-living bacteria in the water column. AB - Worldwide cyanobacterial blooms greatly impair ecosystems in many eutrophic lakes and impact the microbial environment. In particular, large cyanobacterial colonies that are buoyant on the water surface may provide a distinct habitat for bacteria from other small particles that are suspended stably in the water column. To test this hypothesis, bacterial communities (excluding cyanobacteria) attached to large particles dominated by cyanobacterial colonies (>120 MUm, LA), small particles (3-36 MUm, SA), and free-living bacteria (0.2-3 MUm, FL) were investigated monthly for a year in Lake Taihu, China. Results confirmed that the Shannon diversity index of LA was significantly lower than that of FL, which was lower than that of SA. Cytophagia and Alphaproteobacteria were specially enriched in LA. Although samples in each habitat collected during high- (May to November) and low-bloom seasons (December to April) were separated, all samples in LA were clustered and separated from SA and FL, which were also clustered during the same sampling seasons. In addition, the bacterial communities in LA were correlated with nitrate level, whereas FL and SA were correlated with nitrate level and temperature. Mantel analysis revealed that bacterial composition significantly correlated with the cyanobacterial composition in LA and FL but not in SA. These results indicate that LA provides distinct niches to bacteria, whereas the differentiation of bacterial communities in FL and SA is seasonally dependent. PMID- 29573242 TI - Associations of neonatal adiponectin and leptin with growth and body composition in African American infants. AB - BACKGROUND: Cord blood adiponectin and leptin concentrations are associated with birth weight and adiposity. Birth size and rate of infant weight gain are associated with future obesity risk. However, it is unclear whether biomarkers reflecting the intrauterine environment are predictive of infant prospective body composition change. OBJECTIVES: To examine whether cord blood adiponectin and leptin are predictive of neonatal adiposity and fat mass (FM) accrual to 3 months of age. METHODS: Participants (n = 36) were healthy African American infants. Leptin and adiponectin concentrations were measured in umbilical cord blood. At 2 weeks and 3 months, infant body composition was assessed via air displacement plethysmography. Weight-for-length z-scores (WLZ) were calculated using World Health Organization standards. Multiple linear regression was used to examine associations of cord blood adiponectin and leptin with birth WLZ; WLZ, FM and fat free mass at 2 weeks, and the conditional change in these variables from 2 weeks to 3 months (body composition at 3 months adjusted for body composition at 2 weeks). RESULTS: Adiponectin was positively associated with FM at 2 weeks (r = 0.45, P < 0.01), but inversely associated with conditional FM change from 2 weeks to 3 months of age (r = -0.38, P < 0.05). Leptin was not significantly associated with infant body composition. CONCLUSIONS: Adiponectin may be a marker for FM accrual in African American infants, a relatively understudied population with a high long-term obesity risk. Mechanistic studies are needed to determine whether adiponectin directly influences infant growth or is simply a maker reflective of other ongoing biological changes after birth. PMID- 29573243 TI - lncRNA-NKILA/NF-kappaB feedback loop modulates laryngeal cancer cell proliferation, invasion, and radioresistance. AB - Laryngeal cancer is one of the most common head and neck malignant tumors and is commonly resistant to X-ray-based radiotherapy. NF-kappaB interacting lncRNA (NKILA) has been reported to serve as a tumor suppressor in several cancers through combining with NF-kappaB: IkappaB complex thereby inhibiting NF-kappaB activation. Herein, we demonstrated a low NKILA expression in laryngeal cancer and its correlation with shorter overall survival in patients with laryngeal cancer. NKILA serves as a tumor suppressor in laryngeal cancer by suppressing laryngeal cancer cell viability and migration, whereas promoting cell apoptosis; NKILA knockdown reverses the cytotoxicity of X-ray radiation on laryngeal cancer cells through combining with NF-kappaB: IkappaB complex to inhibit IkappaB phosphorylation, inhibit p65 nuclear translocation, and finally inhibit NF-kappaB activation. NF-kappaB binds to the promoter region of NKILA to activate its transcriptional activity, upregulated NKILA then inhibits IkappaB phosphorylation and NF-kappaB activation, thus forming a negative feedback loop to sensitize laryngeal cancer cell to X-ray radiation. In conclusion, NKILA can serve as a promising agent of enhancing the cytotoxicity of X-ray radiation on laryngeal cancer and addressing the radioresistance of laryngeal cancer. PMID- 29573244 TI - Dynamics of coral-associated microbiomes during a thermal bleaching event. AB - Coral-associated microorganisms play an important role in their host fitness and survival. A number of studies have demonstrated connections between thermal tolerance in corals and the type/relative abundance of Symbiodinium they harbor. More recently, the shifts in coral-associated bacterial profiles were also shown to be linked to the patterns of coral heat tolerance. Here, we investigated the dynamics of Porites lutea-associated bacterial and algal communities throughout a natural bleaching event, using full-length 16S rRNA and internal transcribed spacer sequences (ITS) obtained from PacBio circular consensus sequencing. We provided evidence of significant changes in the structure and diversity of coral associated microbiomes during thermal stress. The balance of the symbiosis shifted from a predominant association between corals and Gammaproteobacteria to a predominance of Alphaproteobacteria and to a lesser extent Betaproteobacteria following the bleaching event. On the contrary, the composition and diversity of Symbiodinium communities remained unaltered throughout the bleaching event. It appears that the switching and/or shuffling of Symbiodinium types may not be the primary mechanism used by P. lutea to cope with increasing seawater temperature. The shifts in the structure and diversity of associated bacterial communities may contribute more to the survival of the coral holobiont under heat stress. PMID- 29573245 TI - Primary Autosomal Recessive Distal Renal Tubular Acidosis Caused by a Common Homozygous SLC4A1 Mutation in Two Lao Families. AB - Primary distal renal tubular acidosis (dRTA) caused by mutations of the SLC4A1 gene, which encodes for erythroid and kidney isoforms of anion exchanger, shows marked difference in inheritance patterns and clinical features in different parts of the world. While the disease shows autosomal dominant inheritance without any red cell morphological abnormalities in the temperate countries, it is almost invariably recessive, and often accompanies red cell morphological abnormalities or hemolytic anemia in the tropics, especially in Southeast Asia. Here, we report three patients with autosomal recessive (AR) dRTA, presenting with typical findings of failure to thrive and rickets, from two unrelated Lao families. The mutational analyses revealed that all three patients harbored the same homozygous SLC4A1 mutation, p.Gly701Asp. Adequate supplementation of alkali and potassium resulted in remarkable improvement of growth retardation and skeletal deformities of the patients. This is the first case report of Lao patients with AR dRTA caused by SLC4A1 mutations. PMID- 29573246 TI - Non-Motor Symptom Burdens Are Not Associated with Iron Accumulation in Early Parkinson's Disease: a Quantitative Susceptibility Mapping Study. AB - BACKGROUND: Quantitative susceptibility mapping (QSM) has been used to measure iron accumulation in the deep nuclei of patients with Parkinson's disease (PD). This study examined the relationship between non-motor symptoms (NMSs) and iron accumulation in the deep nuclei of patients with PD. METHODS: The QSM data were acquired from 3-Tesla magnetic resonance imaging (MRI) in 29 patients with early PD and 19 normal controls. The Korean version of the NMS scale (K-NMSS) was used for evaluation of NMSs in patients. The patients were divided into high NMS and low NMS groups. The region-of-interest analyses were performed in the following deep nuclei: red nucleus, substantia nigra pars compacta, substantia nigra pars reticulata, dentate nucleus, globus pallidus, putamen, and head of the caudate nucleus. RESULTS: Thirteen patients had high NMS scores (total K-NMSS score, mean = 32.1), and 16 had low NMS scores (10.6). The QSM values in the deep were not different among the patients with high NMS scores, low NMS scores, and controls. The QSM values were not correlated linearly with K-NMSS total score after adjusting the age at acquisition of brain MRI. CONCLUSION: The study demonstrated that the NMS burdens are not associated with iron accumulation in the deep nuclei of patients with PD. These results suggest that future neuroimaging studies on the pathology of NMSs in PD should use more specific and detailed clinical tools and recruit PD patients with severe NMSs. PMID- 29573247 TI - Safety and Immunogenicity of an Egg-Cultivated Quadrivalent Inactivated Split virion Influenza Vaccine (GC3110A) in Healthy Korean Children: a Randomized, Double-blinded, Active-controlled Phase III Study. AB - BACKGROUND: The frequency with which the 2 B lineages have been found to cocirculate in a season has been on the rise, which has spurred the need for a quadrivalent influenza vaccine (QIV) to protect against both B lineages. The World Health Organization (WHO) recommended that QIV include both B lineages beginning in the 2013-2014 flu season. This study was conducted to evaluate the immunogenicity and safety of an egg-cultivated QIV in healthy Korean children and adolescents aged >= 6 months to < 19 years. METHODS: A total of 528 subjects were randomized 4:1 to receive either a QIV (GC3110A) or a trivalent influenza vaccine. Hemagglutination inhibition antibody responses were assessed 28 days after the last dose. Safety was also evaluated. RESULTS: The proportion of subjects in the GC3110A group who achieved seroconversion was confirmed to exceed 40% across all age groups. The proportion of subjects aged >= 6 months to < 3 years in the GC3110A group who achieved seroprotection failed to meet the Ministry of Food and Drug Safety (MFDS) standard of 70%. Potential causes may include the small number of subjects, as well as the small dosage. However, results pertaining to the other age groups satisfied the MFDS standard. The safety profile was also comparable to that of the control. CONCLUSION: The new quadrivalent split influenza vaccine may offer broader protection to children and adolescents aged >= 3 years to < 19 years of age against both influenza B lineages than the existing trivalent influenza vaccines (Registered at the ClinicalTrials.gov NCT02541253). PMID- 29573248 TI - Comparison between Newly Developed and Commercial Inhalant Skin Prick Test Reagents Using In Vivo and In Vitro Methods. AB - BACKGROUND: We developed skin prick test (SPT) reagents for common inhalant allergens that reflected the real exposure in Korea. The study aim was to evaluate diagnostic usefulness and allergen potency of our inhalant SPT reagents in comparison with commercial products. METHODS: We produced eight common inhalant allergen SPT reagents using total extract (Prolagen): Dermatophagoides farinae, Dermatophagoides pteronyssinus, oak, ragweed, mugwort, Humulus japonicus pollens, as well as cat and dog allergens. We compared the newly developed reagents with three commercially available SPT reagents (Allergopharma, Hollister Stier, Lofarma). We measured total protein concentrations, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), major allergen concentration, and biological allergen potencies measured by immunoglobulin E (IgE) immunoblotting and ImmunoCAP inhibition test. RESULTS: Diagnostic values of these SPT reagents were expressed as positivity rate and concordance rate of the results from ImmunoCAP allergen-specific IgE test in 94 allergic patients. In vitro analysis showed marked differences in protein concentrations, SDS-PAGE features, major allergen concentrations, and biological allergen potencies of four different SPT reagents. In vivo analysis showed that positive rates and concordance rates of Prolagen(r) SPT reagents were similar compared to the three commercial SPT reagents. CONCLUSION: The newly developed Prolagen(r) inhalant SPT reagents are not inferior to the commercially available SPT reagents in allergy diagnosis. PMID- 29573250 TI - Will a Quadrivalent Vaccine Solve the Problem of Influenza B Mismatches? PMID- 29573249 TI - The Risk of Spontaneous Preterm Birth according to Maternal Pre-pregnancy Body Mass Index in Twin Gestations. AB - BACKGROUND: Maternal obesity is a well-known risk factor for both total preterm birth (PTB) and spontaneous PTB in singleton gestation, whereas this association is not well determined in multiple pregnancy. The objective of this study was to determine the risk of spontaneous PTB according to the pre-pregnancy body mass index (BMI) in twin gestations. METHODS: The association between the risk of PTB and pre-pregnancy BMI was determined in women pregnant with twins between 2004 and 2014. Pre-pregnancy BMI values were divided into three groups (underweight/normal/overweight and obese). PTB was classified as spontaneous PTB (following preterm premature rupture of membranes, preterm labor, or cervical insufficiency) or medically indicated PTB (cesarean section or induction of labor because of maternal/fetal indications). RESULTS: A total of 1,959 women were included in the analysis, and the percentages of total PTB and spontaneous PTB were 13.1% and 9.3%. The percentages of total PTB and spontaneous PTB in three groups were 14.1%, 11.9%, 16.3%, respectively, and 11.0%, 8.0%, 12.5% (P < 0.05 between normal and overweight/obese women). The risks of total and spontaneous PTB in overweight/obese women were higher than those in women with normal weight, even after adjustment for prior history of PTB, age, maternal height, parity, in vitro fertilization-embryo transfer (IVF-ET) (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.01-2.03; OR, 1.58; 95% CI, 1.05-2.36). CONCLUSION: The risks of both total and spontaneous PTB were significantly greater in the overweight/obese group than in the normal BMI group.

AB - We describe a Monte Carlo model of the mouse torso to optimize illumination of the mouse lung for fluorescence detection of low levels of pulmonary pathogens, specifically Mycobacterium tuberculosis. After validation of the simulation with an internally illuminated optical phantom, the entire mouse torso was simulated to compare external and internal illumination techniques. Measured optical properties of deflated mouse lungs were scaled to mimic the diffusive properties of inflated lungs in vivo. Using the full-torso model, a 2 * to 3 * improvement in average fluence rate in the lung was seen for dorsal compared with ventral positioning of the mouse with external illumination. The enhancement in average fluence rate in the lung using internal excitation was 40 * to 60 * over external illumination in the dorsal position. Parameters of the internal fiber optic source were manipulated in the model to guide optimization of the physical system and experimental protocol for internal illumination and whole body detection of fluorescent mycobacteria in a mouse model of infection. PMID- 29573252 TI - Up-regulation of IGF Binding Protein-3 Inhibits Colonic Inflammatory Response. AB - BACKGROUND: The aggravating factors still remained unclear in inflammatory bowel disease (IBD). Despite many different therapeutic approaches, many patients do not respond to the therapy. The anti-inflammatory effect of insulin-like growth factor-binding protein-3 (IGFBP-3) was suggested because of its capability of nuclear factor-kappaB (NF-kappaB) signaling inhibition. Therefore, we hypothesized that the up-regulation of IGFBP-3 would inhibit an inflammatory process. METHODS: Lipopolysaccharides (LPS) treated intestinal epithelial cell 6 (IEC-6) and dextran sodium sulfate (DSS) induced colitis mice were used as colitis models. Exogenous IGFBP-3 expression was accomplished using the adenoviral vector system expressing IGFBP-3 (Ad/IGFBP-3). The inflammatory responses and relevant cellular responses in IEC-6 cells influenced by IGFBP-3 expression were evaluated by western blotting, 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay, and reactive oxygen species (ROS) measurement. The severity of colitis was evaluated with the colon tissues of DSS induced mouse model. RESULTS: We found that the IGFBP-3 expression reduced the production of inflammatory cytokines (cyclooxygenase-2, interleukin-1beta, tumor necrosis factor-alpha) and ROS formation. IGFBP-3 expression also induced cell viability and inhibited NF-kappaB activation. In line with this data, the severity of DSS-induced mouse colitis was greatly ameliorated by the treatment of IGFBP-3 expressing adenoviral particles characterized with less weight loss and preserved colon length compared with the mice treated with DSS alone. The histopathology of the colon showed the reducing signs of colitis in Ad/IGFBP-3 treated DSS-mice group. CONCLUSION: Therefore, our data suggest that Ad/IGFBP-3 up-regulation reduces colonic inflammatory response as a novel therapeutic protocol for IBD.

AB - We report a photoacoustic computed tomography (PACT) system using a customized optical fiber with a cylindrical diffuser to internally illuminate deep targets. The traditional external light illumination in PACT usually limits the penetration depth to a few centimeters from the tissue surface, mainly due to strong optical attenuation along the light propagation path from the outside in. By contrast, internal light illumination, with external ultrasound detection, can potentially detect much deeper targets. Different from previous internal illumination PACT implementations using forward-looking optical fibers, our internal-illumination PACT system uses a customized optical fiber with a 3-cm long conoid needle diffuser attached to the fiber tip, which can homogeneously illuminate the surrounding space and substantially enlarge the field of view. We characterized the internal illumination distribution and PACT system performance. We performed tissue phantom and in vivo animal studies to further demonstrate the superior imaging depth using internal illumination over external illumination. We imaged a 7.5-cm-deep leaf target embedded in optically scattering medium and the beating heart of a mouse overlaid with 3.7-cm-thick chicken tissue. Our results have collectively demonstrated that the internal light illumination combined with external ultrasound detection might be a useful strategy to improve the penetration depth of PACT in imaging deep organs of large animals and humans.

AB - While iron is essential to sustain growth, its excess can be detrimental to the cell by generating highly toxic reactive oxygen species. Regulation of iron homeostasis thus plays a vital role in almost all living organisms. During the last 15 years, the small RNA (sRNA) RyhB has been shown to be a key actor of iron homeostasis regulation in bacteria. Through multiple molecular mechanisms, RyhB represses expendable iron-utilizing proteins, promotes siderophore production, and coordinates Fe-S cluster cofactor biogenesis, thereby establishing a so called iron-sparing response. In this review, we will summarize knowledge on how sRNAs control iron homeostasis mainly through studies on RyhB in Escherichia coli. The parallel roles and modes of action of other sRNAs in different bacteria will also be described. Finally, we will discuss what questions remain to be answered concerning this important stress response regulation by sRNAs. PMID- 29573258 TI - Carbohydrate Utilization in Bacteria: Making the Most Out of Sugars with the Help of Small Regulatory RNAs. AB - Survival of bacteria in ever-changing habitats with fluctuating nutrient supplies requires rapid adaptation of their metabolic capabilities. To this end, carbohydrate metabolism is governed by complex regulatory networks including posttranscriptional mechanisms that involve small regulatory RNAs (sRNAs) and RNA binding proteins. sRNAs limit the response to substrate availability and set the threshold or time required for induction and repression of carbohydrate utilization systems. Carbon catabolite repression (CCR) also involves sRNAs. In Enterobacteriaceae, sRNA Spot 42 cooperates with the transcriptional regulator cyclic AMP (cAMP)-receptor protein (CRP) to repress secondary carbohydrate utilization genes when a preferred sugar is consumed. In pseudomonads, CCR operates entirely at the posttranscriptional level, involving RNA-binding protein Hfq and decoy sRNA CrcZ. Moreover, sRNAs coordinate fluxes through central carbohydrate metabolic pathways with carbohydrate availability. In Gram-negative bacteria, the interplay between RNA-binding protein CsrA and its cognate sRNAs regulates glycolysis and gluconeogenesis in response to signals derived from metabolism. Spot 42 and cAMP-CRP jointly downregulate tricarboxylic acid cycle activity when glycolytic carbon sources are ample. In addition, bacteria use sRNAs to reprogram carbohydrate metabolism in response to anaerobiosis and iron limitation. Finally, sRNAs also provide homeostasis of essential anabolic pathways, as exemplified by the hexosamine pathway providing cell envelope precursors. In this review, we discuss the manifold roles of bacterial sRNAs in regulation of carbon source uptake and utilization, substrate prioritization, and metabolism. PMID- 29573256 TI - Global Regulation by CsrA and Its RNA Antagonists. AB - The sequence-specific RNA binding protein CsrA is employed by diverse bacteria in the posttranscriptional regulation of gene expression. Its binding interactions with RNA have been documented at atomic resolution and shown to alter RNA secondary structure, RNA stability, translation, and/or Rho-mediated transcription termination through a growing number of molecular mechanisms. In Gammaproteobacteria, small regulatory RNAs (sRNAs) that contain multiple CsrA binding sites compete with mRNA for binding to CsrA, thereby sequestering and antagonizing this protein. Both the synthesis and turnover of these sRNAs are regulated, allowing CsrA activity to be rapidly and efficiently adjusted in response to nutritional conditions and stresses. Feedback loops between the Csr regulatory components improve the dynamics of signal response by the Csr system. The Csr system of Escherichia coli is intimately interconnected with other global regulatory systems, permitting it to contribute to regulation by those systems. In some species, a protein antagonist of CsrA functions as part of a checkpoint for flagellum biosynthesis. In other species, a protein antagonist participates in a mechanism in which a type III secretion system is used for sensing interactions with host cells. Recent transcriptomics studies reveal vast effects of CsrA on gene expression through direct binding to hundreds of mRNAs, and indirectly through its effects on the expression of dozens of transcription factors. CsrA binding to base-pairing sRNAs and novel mRNA segments, such as the 3' untranslated region and deep within coding regions, predict its participation in yet-to-be-discovered regulatory mechanisms.

AB - The 2013-2016 Ebola outbreak in West Africa has been the largest ever of a known disease in a new context that produced an unprecedented impact and is changing the international approach to responding to public health emergencies. The unprecedented scale of the outbreak, the use of advanced technology for detecting and characterizing the infectious agent, along with the opportunity to treat patients in modern facilities have greatly increased our knowledge of the disease and its transmission. Also, for the first time, an important international effort has been deployed to control the spread of the epidemic by providing care to patients and by adopting basic measures of public health control. Apart from supportive treatment and intensive therapy with fluids and electrolytes, no new compounds have been proved to be clinically effective to treat Ebola virus disease; however, a specific vaccine has shown significant protection in clinical trials in Guinea, opening an expectation for controlling future outbreaks.

PMID- 29573261 TI - Development of novel monoclonal antibodies to dog leukocyte antigen DR displaying direct and immune-mediated cytotoxicity toward canine lymphoma cell lines. AB - Spontaneous canine lymphoma (CL) has become a promising, nonrodent model for advancing the therapeutic strategies of human hematological malignancies. As new resources for veterinary and comparative studies on CL-associated antigens, we developed 2 novel mouse monoclonal antibodies, denoted B5 and E11, that recognized the canine major histocompatibility Class II DR antigens (dog leukocyte antigen DR). Using flow cytometry and solid phase immunoenzymatic assays, we showed that the antigens recognized by B5 and E11 were strongly expressed in several CL cell lines and the ex vivo canine neoplastic cells of B and mixed B/T immunophenotypes. Additionally, we evaluated a minimal cross reactivity of B5 and E11 with the human B-cell line, Raji. By the ectopic expression of the hybrid murine/canine I-E/DR dimers in the HEK293 cells, we demonstrated that the epitope of B5 was localized to the invariant DRalpha chain, whereas the epitope of E11 was collectively formed by the DRalpha and DRbeta chains. Both epitopes were conformational and conserved in all the tested unrelated individuals of different dog breeds. In vitro treatment of 2 CL B-cell lines (CLBL1 and CLB70) with B5 and E11 rapidly induced a direct apoptotic cell death. Similarily, both mouse monoclonal antibodies efficiently killed the above cell lines through the mechanisms of complement-dependent and antibody-mediated cellular phagocytosis. Collectively, our data support the further development of B5 and E11 as novel tools for dog leukocyte antigen DR-targeted, preclinical trials involving CL. PMID- 29573262 TI - Effect of Bronsted acidic ionic liquid 1-(1-propylsulfonic)-3-methylimidazolium chloride on growth and co-fermentation of glucose, xylose and arabinose by Zymomonas mobilis AX101. AB - : The potential of large-scale lignocellulosic biomass hydrolysis to fermentable sugars using ionic liquids has increased interest in this green chemistry route to fermentation for fuel-ethanol production. The ionic liquid 1-(1 propylsulfonic)-3-methylimidazolium chloride compared to other reported ionic liquids has the advantage of hydrolysing lignocellulosic biomass to reducing sugars at catalytic concentrations (<=0.032 mol l-1 ) in a single step. However, effects of this ionic liquid on co-fermentation of glucose, xylose and arabinose to ethanol by recombinant Zymomonas mobilisAX101 has not been studied. Authentic glucose, xylose and arabinose were used to formulate fermentation media at varying catalytic 1-(1-propylsulfonic)-3-methylimidazolium chloride concentrations for batch co-fermentation of the sugars using Z. mobilisAX101. The results showed that at 0.008, 0.016 and 0.032 mol l-1 ionic liquid in the culture medium, cell growth decreased by 10, 27 and 67% respectively compared to the control. Ethanol yields were 62.6, 61.8, 50.5 and 23.1% for the control, 0.008, 0.016 and 0.032 mol l-1 ionic liquid respectively. The results indicate that lignocellulosic biomass hydrolysed using 0.008 mol l-1 of 1-(1-propylsulfonic)-3 methylimidazolium chloride would eliminate an additional separation step and provide a ready to use fermentation substrate. SIGNIFICANCE AND IMPACT OF STUDY: This is the first reported study of the effect of the Bronsted acidic ionic liquid 1-(1-propylsulfonic)-3-methylimidazolium chloride on growth and co fermentation of glucose, xylose and arabinose by Zymomonas mobilisAX101 in batch culture. Growth on and co-fermentation of the sugars by Z. mobilisAX 101 with no significant inhibition by the ionic liquid at the same catalytic amounts of 0.008 mol l-1 used to hydrolyse lignocellulosic biomass to reducing sugars overcome two major hurdles that adversely affect the process economics of large-scale industrial cellulosic fuel ethanol production; the energy-intensive hydrolysis and ionic liquid separation steps. PMID- 29573263 TI - Effect of pre-operative methylprednisolone on orthostatic hypotension during early mobilization after total hip arthroplasty. AB - BACKGROUND: Orthostatic hypotension (OH) and intolerance (OI) are common after total hip arthroplasty (THA) and may delay early mobilization. The pathology of OH and OI includes a dysregulated post-operative vasopressor response, by a hitherto unknown mechanism. We hypothesized that OI could be related to the inflammatory stress response which is inhibited by steroid administration. Consequently, this study evaluated the effect of a pre-operative high-dose methylprednisolone on OH and OI early after THA. METHODS: Randomized, double blind, placebo-controlled study in 59 patients undergoing elective unilateral THA with spinal anesthesia and a standardized multimodal analgesic regime. Patients were allocated (1 : 1) to pre-operative intravenous (IV) methylprednisolone (MP) 125 mg or isotonic saline (C). OH, OI and cardiovascular responses to sitting and standing were evaluated using a standardized mobilization protocol pre operatively, 6, and 24 h after surgery. Systolic and diastolic arterial pressure and heart rate were measured non-invasively (Nexfin(r) ). The systemic inflammation was monitored by the C-reactive protein (CRP) response. RESULTS: At 6 h post-operatively, 11 (38%) versus 11 (37%) patients had OH in group MP and group C, respectively (RR 1.02 (0.60 to 1.75; P = 1.00)), whereas OI was present in 9 (31%) versus 13 (43%) patients (RR 0.76 (0.42 to 1.36; P = 0.42)), respectively. At 24 h post-operatively, the prevalence of OH and OI did not differ between groups, though CRP levels were significantly reduced in group MP (P < 0.001). CONCLUSION: Pre-operative administration of 125 mg methylprednisolone IV did not reduce OH or OI compared with placebo despite a reduced inflammatory response. PMID- 29573264 TI - Age-related differences in sequence learning: Findings from two visuo-motor sequence learning tasks. AB - The Serial Reaction Time Task (SRTT) is thought to assess implicit learning, which seems to be preserved with age. However, the reaction time (RT) measures employed on implicit-like tasks might be too unreliable to detect individual differences. We investigated whether RT-based measures mask age effects by comparing the performance of 43 younger and 35 older adults on SRTT and an explicit-like Predictive Sequence Learning Task (PSLT). RT-based measures (difference scores and a ratio) were collected for both tasks, and accuracy was additionally measured for PSLT. We also measured fluid abilities. The RT difference scores indicated preserved SRTT and PSLT performance with age and did not correlate with fluid abilities, while ratio RT and the accuracy-based measures indicated age-related decline and correlated with fluid abilities. Therefore, RT-difference scores might mask individual differences, which compromises the interpretation of previous studies using SRTT.

PMID- 29573266 TI - Sorafenib paradoxically activates the RAS/RAF/ERK pathway in polyclonal human NK cells during expansion and thereby enhances effector functions in a dose- and time-dependent manner. AB - Natural killer (NK) cells play a major role in host immunity against leukaemia and lymphoma. However, clinical trials applying NK cells have not been as efficient as hoped for. Patients treated with rapidly accelerated fibrosarcoma (RAF) inhibitors exhibit increased tumour infiltration by immune cells, suggesting that a combination of RAF inhibitors with immunotherapy might be beneficial. As mitogen-activated protein kinases (MAPKs) such as raf-1 proto oncogene, serine/threonine kinase (CRAF) regulate NK cell functions, we performed an in-vitro investigation on the potential of clinically relevant short-acting tyrosine kinase inhibitors (TKIs) as potential adjuvants for NK cell therapy: NK cells from healthy human blood donors were thus treated with sorafenib, sunitinib or the pan-RAF inhibitor ZM336372 during ex-vivo expansion. Functional outcomes assessed after washout of the drugs included cytokine production, degranulation, cytotoxicity, apoptosis induction and signal transduction with/without target cell contact. Paradoxically, sorafenib enhanced NK cell effector functions in a time- and dose-dependent manner by raising the steady-state activation level. Of note, this did not lead to NK cell exhaustion, but enhanced activity against target cells such as K562 or Daudis mediated via the RAS/RAF/extracellular regulated kinase (ERK) pathway, but not via protein kinase B (AKT). Our data will pave the path to develop a rationale for the considered use of RAF inhibitors such as sorafenib for pre-activation in NK cell-based adoptive immune therapy. PMID- 29573267 TI - Dietary Fatty Acids Differentially Regulate Secretion of Adiponectin and Interleukin-6 in Primary Canine Adipose Tissue Culture. AB - The aim of this study was to determine the effect of n3 polyunsaturated fatty acids (PUFA) on canine adipose tissue secretion of adiponectin, interleukin-6 (IL6), and tumor necrosis factor-alpha (TNFalpha). Subcutaneous and omental visceral adipose tissue samples were collected from 16 healthy intact female dogs. Concentrations of adiponectin were measured in mature adipocyte cultures, and concentrations of IL6 and TNFalpha were measured in undifferentiated stromovascular cell (SVC) cultures following treatment with eicosapentaenic acid (EPA, 20:5n-3), arachidonic acid (ARA, 20:4n-6), or palmitic acid (PAM, 16:0) at 25, 50, or 100 MUM. Secretion of adiponectin from mature adipocytes was higher (p < 0.001) following EPA treatment at 50 MUM compared to control in subcutaneous tissue, and higher following EPA treatment compared to PAM treatment at 25 MUM in both subcutaneous (p < 0.001) and visceral tissues (p = 0.010). Secretion of IL6 from SVC derived from subcutaneous tissue was lower following EPA treatment and higher following PAM treatment compared to control both at 50 MUM (p = 0.001 and p = 0.041, respectively) and 100 MUM (p = 0.013 and p < 0.001, respectively). These findings of stimulation of adiponectin secretion and inhibition of IL6 secretion by EPA, and stimulation of IL6 secretion by PAM, are consistent with findings of increased circulating concentrations of adiponectin and decreased circulating concentration of IL6 in dogs supplemented with dietary fish oil, and show that the effect of fish oil on circulating concentrations of adiponectin and IL6 is, at least partially, the result of local effects of EPA and PAM on adipose tissue. PMID- 29573268 TI - Simulations of optically switchable molecular machines for particle transport. AB - A promising application for design and deployment of molecular machines is nanoscale transport, driven by artificial cilia. In this contribution, we present several further steps toward this goal, beyond our first-generation artificial cilium (Raeker et al., J. Phys. Chem. A 2012, 116, 11241). Promising new azobenzene-derivatives were tested for use as cilium motors. Using a QM/MM partitioning in on-the-fly photodynamics, excited-state surface-hopping trajectories were calculated for each isomerization direction and each motor version. The methods used were reparametrized semiempirical quantum chemistry together with floating-occupation configuration interaction as the QM part and the OPLSAA-L forcefield as MM part. In addition, we simulated actual particle transport by a single cilium attached to a model surface, with varying attachment strengths and modes, and with transport targets ranging from single atoms to multi-molecule arrangements. Our results provide valuable design guidelines for cilia-driven nanoscale transport and emphasize the need to carefully select the whole setup (not just the cilium itself, but also its surface attachment and the dynamic cilium-target interaction) to achieve true transport.

AB - BACKGROUND: Lack of time and access to equipment are recognised barriers to simulation training. AIM: To investigate the effect of a take-home laparoscopic simulator training program on the laparoscopic skills of gynaecology trainees. METHOD: Participants (n = 17 in 2015, n = 16 in 2016) were supplied with a box trainer, associated equipment and instructions on self-directed training. A program was designed and implemented in 2015 comprising of ten weekly laparoscopic skills tasks and modified in 2016 to eight monthly tasks. Half of the participants were randomly allocated a supervisor. Participants performed baseline and post-training assessments of laparoscopic skills in a box trainer task (thread transfer) and virtual reality simulator tasks (laparoscopic tubal ligation and bilateral oophorectomy). RESULTS: Trainees in 2015 demonstrated an improvement in the median time to complete the laparoscopic tubal ligation task (baseline 124 s vs post-training 91 s, P = 0.041). There was no difference in the number of tubal ligation bleeding incidents, or in the time taken to complete the box trainer thread transfer task. In 2016 trainees demonstrated improvement in tubal ligation time (baseline 251 vs 71 post-training, P = 0.021) and bilateral oophorectomy time (baseline 891 s vs 504 post-training, P = 0.025). There was no significant difference in other outcome measures. There was no difference found in performance when groups were compared by supervisor allocation. CONCLUSION: A take-home box trainer simulation-training program was associated with improvement in laparoscopic skills. This type of program may improve trainee access to simulation training. PMID- 29573270 TI - Identifying the germ cells during embryogenesis and gametogenesis by germ-line gene vasa in an anadromous fish, American shad Alosa sapidissima. AB - American shad Alosa sapidissima, an anadromous clupeid, exhibits variation in reproductive strategies, including semelparity and iteroparity. It provides an excellent model for studying the behaviour of germ cells in anadromous fish during their migration from sea to river. The vasa gene was characterized in A. sapidissima as a germ-cell marker to elaborate the process of germ-cell development and differentiation in anadromous species. A complementary (c)DNA fragment of 819 bp, partial open reading frame (ORF), was cloned by degenerate PCR and named as ASvas. In adult A. sapidissima, vasa transcript was exclusively detected in gonads by reverse-transcription (RT)-PCR. Through chromogenic in situ hybridization, the vasa messenger (m)RNA was specifically detected in primordial germ cells (PGC) in embryos and germ cells at early stages in ovary and testis. Besides, the cellular distribution profile of Vasa protein also proved that vasa gene could be used as a germ-line marker to trace the PGCs migration during embryogenesis and the germ-cell differentiation during gametogenesis in A. sapidissima. During embryogenesis, the migrating PGCs were clearly detected at tail-bud stage and the PGCs reached the genital ridge at the stage of pre hatching stage in A. sapidissima embryos. During gametogenesis, the Vasa protein was dynamically expressed in differentiating germ cells at different stages in adult gonads. As far as we know, this is the first report to demonstrate the PGCs migration and germ-cell differentiation through vasa gene expression in the anadromous species. The findings will pave a way for investigating germ-cell development and maturation in the A. sapidissima and other anadromous fish. PMID- 29573271 TI - A study of skin disease spectrum occurring in Angola phototype V-VI population in Luanda. AB - BACKGROUND: Prevalence of skin diseases in Luanda (Angola) is unknown, and publications are barely found in the literature. We aim to describe, for the first time, the frequency of skin disease spectrum in phototype V-VI Angolan population in Luanda City. METHODS: We included Fitzpatrick phototype V-VI Angolan patients who consulted the Dermatology Unit in Luanda Medical Center during a 1-year period. Medical information was recovered from the electronic database, and diagnoses were based on ICD-10. Only the main complaint was registered, and the results were classified according to age and sex. Criteria exclusion consisted of incomplete clinical records, Fitzpatrick phototype I-IV Angolan, or foreign patients from the study. RESULTS: From a total of 3938 patients, 3554 met the inclusion criteria, of which 2742 were adults 13 years or older. In this group, acne (23.6%), dermatophytosis (11.0%), and pityriasis versicolor (8.6%) were the main complaints. On the other hand, in the pediatric population (n = 812), atopic dermatitis (29.4%), tinea capitis (13.7%), and molluscum contagiosum (12.5%) were the most frequent disorders. In adult females, acne (31.3%) was the main condition, while in adult males, dermatophytosis (13.5%). In children, the frequency of atopic dermatitis was comparable: 29.1% and 28.6% in girls and boys, respectively. CONCLUSIONS: We published for the first time the frequency of the skin disease spectrum in Fitzpatrick phototype V VI Angolan population in Luanda City, highlighting the prevalence of acne, dermatophytosis, and atopic dermatitis.

AB - OBJECTIVES: To study topical corticosteroid use in Dutch asthmatic children using pharmacy dispensing data and to assess whether Dutch physicians prescribe topical corticosteroids in this population according to clinical guidelines. METHODS: Medication histories of children using asthma medication were extracted from the pharmacy dispensing system in 100 Dutch community pharmacies. The incidence rate and the potency of topical corticosteroid prescriptions per age were assessed. The topical corticosteroid incidence rates of the different age groups were compared using the Pearson chi-square test. Generalized linear models were used to study the prescription behavior of general practitioners and atopic dermatitis related specialists regarding different classes of topical corticosteroids. RESULTS: Thirty percent of the infants received a topical corticosteroid prescription, compared with 15%-18% of the children aged 4 and older. Similarly, the mean number of topical corticosteroid prescriptions in infants was 2.2 per year, compared with 1.6-1.9 in children aged 4 and older. In concordance with the clinical guidelines, we observed that atopic dermatitis-related specialists more often prescribed first prescriptions of potent and very potent topical corticosteroids than general practitioners (relative risk = 2.55, 95% confidence interval = 1.79-3.63). Statistically significant differences (P < .01) were found between potencies of prescribed topical corticosteroids. CONCLUSION: Younger children receive more topical corticosteroid prescriptions than children aged 4 and older, and there is a statistically significantly higher prescription rate of topical corticosteroid for infants. Sometimes general practitioners do not follow guidelines and prescribe more-potent topical corticosteroids without a prior prescription of the same potency by a specialist. PMID- 29573275 TI - A role for ALF4 during gall and giant cell development in the biotic interaction between Arabidopsis and Meloidogyne spp. AB - Root-knot nematodes (RKNs; Meloidogyne spp.) are a major pest for the agriculture worldwide. RKNs induce specialized feeding cells (giant cells, GCs) inside galls which are de novo formed pseudo-organs in the roots that share similarities with other developmental processes as lateral root (LR) and callus formation or grafting involving new vascular development or pericycle proliferation. Hence, it is pertinent to study the molecular mechanisms directing the plant-nematode interaction. In this respect, ALF4 is a key gene during LR formation, vascular vessels reconnection in grafting, hormone-induced callus formation or de novo root organogenesis from leaf explants. Our results show that ALF4 is also induced in galls at early infection stages in an auxin-independent way. Furthermore, ALF4 activity is necessary for the formation of proper galls and GCs, as the mutant alf4-1 presents aberrant galls and GCs with severe structural abnormalities leading to a dramatic reduction in the nematode egg production. However, a low reproduction rate is maintained, that might be explained by the local auxin maximum build by the nematodes in galls, partially rescuing alf4-1 phenotype. This would be similar to the partial rescue described for LR formation with exogenous auxins and also agrees with the LR emergence from alf4-1 galls but not from uninfected roots. In addition, ALF4 is also induced in syncytia formed by cyst nematodes. All these data support a pivotal role for ALF4 during de novo organogenesis processes induced by endoparasitic nematodes, in addition to its role in LR formation, callus development or vessel reconnection during grafting. PMID- 29573274 TI - Listen to the public and fulfil their information interests - translating vaccine communication research findings into guidance for regulators. AB - Regulatory authorities have a crucial role in communicating about the vaccines they license. In terms of content and timing, their communication to the public is usually driven by data on quality, safety and efficacy. However, concerns over safety and vaccine hesitancy have emerged in some communities in various countries, and this demands a new approach to communication, starting with listening to the public debate. Reviewing communication research findings, coming in particular from the cognitive, decision-making and media sciences, constitutes one mechanism of listening and has led the European Union (EU) regulatory network to developing guidance about which common concerns and information needs of the public to address through proactive and prepared communication. The guidance has been welcomed by EU and international fora. The current article summarizes the recommendations and shares the underlying research findings, as well as a proof of concept that communication research can be valuable for regulators. It is critical that regulators integrate the communication process with product risk assessment in the framework of pharmacovigilance, to ensure that public concerns are addressed in the assessments and that information about evidence and uncertainty relating to safety is provided to the public and vaccination policy makers in a specific, clear and accurate manner. Additionally, information from regulatory authorities should support healthcare professionals in their communication with patients. Meeting the information interests of the public is the principal prerequisite for informed decisions as well as safe and effective use of vaccines and medicines overall. This is also fundamental for trust in the authorities' commitment to patient and population health. PMID- 29573277 TI - The effects of the Union for International Cancer Control/American Joint Committee on Cancer Tumour, Node, Metastasis system version 8 on staging of differentiated thyroid cancer: a comparison to version 7. AB - OBJECTIVE: To assess the changes resulting from the changes from UICC/AJCC TNM version 7 to version 8 and to subsequently determine whether TNM version 8 is an improvement compared to previous iterations of the TNM system and other staging systems for differentiated thyroid cancer (DTC) with regard to prognostic power. DESIGN: Database study of DTC patients treated in our centre between 1978 up to and including 1 July 2014. Results were compared to our previous comparison of prognostic systems using the same data set. PATIENTS: 2257 DTC patients. MEASUREMENTS: Staging in accordance with TNM 7 and TNM 8. Thyroid cancer-specific mortality; comparison was based on p-values of univariate Cox regression analyses as well as analysis of the proportion of variance explained (PVE). RESULTS: There is a redistribution from stage 3 to lower stages affecting 206 (9.1%) patients. DTC-related mortality according to Kaplan-Meier for younger and older patients in TNM 7 had a slightly lower prognostic power than that in accordance with TNM 8 (P = 8.0 10-16 and P = 1.5 10-21 , respectively). Overall staging is lower in 627/2257 (27.8%) patients. PVE (TNM 7: 0.29; TNM 8: 0.28) and the P-value of Cox regressions (TNM 7: P = 7.1*10-52 ; TNM 8: P = 3.9*10-49 ) for TNM version 8 are marginally lower than that for TNM version 7, but still better than for any other DTC staging system. CONCLUSION: TNM 8 results in a marked downstaging of patients compared to TNM 7. Although some changes, like the change in age boundary, appear to be associated with an improvement in prognostic power, the overall effect of the changes does not improve the predictive power compared to TNM 7. PMID- 29573276 TI - Sinusoidal voltage protocols for rapid characterisation of ion channel kinetics. AB - KEY POINTS: Ion current kinetics are commonly represented by current-voltage relationships, time constant-voltage relationships and subsequently mathematical models fitted to these. These experiments take substantial time, which means they are rarely performed in the same cell. Rather than traditional square-wave voltage clamps, we fitted a model to the current evoked by a novel sum-of sinusoids voltage clamp that was only 8 s long. Short protocols that can be performed multiple times within a single cell will offer many new opportunities to measure how ion current kinetics are affected by changing conditions. The new model predicts the current under traditional square-wave protocols well, with better predictions of underlying currents than literature models. The current under a novel physiologically relevant series of action potential clamps is predicted extremely well. The short sinusoidal protocols allow a model to be fully fitted to individual cells, allowing us to examine cell-cell variability in current kinetics for the first time. ABSTRACT: Understanding the roles of ion currents is crucial to predict the action of pharmaceuticals and mutations in different scenarios, and thereby to guide clinical interventions in the heart, brain and other electrophysiological systems. Our ability to predict how ion currents contribute to cellular electrophysiology is in turn critically dependent on our characterisation of ion channel kinetics - the voltage-dependent rates of transition between open, closed and inactivated channel states. We present a new method for rapidly exploring and characterising ion channel kinetics, applying it to the hERG potassium channel as an example, with the aim of generating a quantitatively predictive representation of the ion current. We fitted a mathematical model to currents evoked by a novel 8 second sinusoidal voltage clamp in CHO cells overexpressing hERG1a. The model was then used to predict over 5 minutes of recordings in the same cell in response to further protocols: a series of traditional square step voltage clamps, and also a novel voltage clamp comprising a collection of physiologically relevant action potentials. We demonstrate that we can make predictive cell-specific models that outperform the use of averaged data from a number of different cells, and thereby examine which changes in gating are responsible for cell-cell variability in current kinetics. Our technique allows rapid collection of consistent and high quality data, from single cells, and produces more predictive mathematical ion channel models than traditional approaches.

The occurrence of mycorrhizas is now well established in c. 85% of extant plants, yet the geological record of these associations is sparse. Fossils preserved under exceptional conditions provide tantalizing glimpses into the evolutionary history of mycorrhizas, showing the extent of their occurrence and aspects of their evolution in extinct plants. The fossil record has important roles to play in establishing a chronology of when key fungal associations evolved and in understanding their importance in ecosystems through time. Together with calibrated phylogenetic trees, these approaches extend our understanding of when and how groups evolved in the context of major environmental change on a global scale. Phylogenomics furthers this understanding into the evolution of different types of mycorrhizal associations, and genomic studies of both plants and fungi are shedding light on how the complex set of symbiotic traits evolved. Here we present a review of the main phases of the evolution of mycorrhizal interactions from palaeontological, phylogenetic and genomic perspectives, with the aim of highlighting the potential of fossil material and a geological perspective in a cross-disciplinary approach.

AB - OBJECTIVE: The utility of fluorodeoxyglucose positron emission tomography (FDG PET) imaging to predict outcome has been well-established for patients undergoing definitive radiation in the initial management of head and neck cancer. However, the usefulness of this modality in the recurrent setting remains uncertain. We sought to evaluate the prognostic value of metabolic tumor parameters measured on FDG-PET in patients treated by reirradiation for recurrent head and neck cancer. METHODS: Thirty-four tumors occurring in 29 patients were reirradiated and were evaluable. The most common disease sites were the oropharynx (n = 9), oral cavity (N = 8), and nasopharynx (n = 6). Potential correlations of FDG-PET maximum standardized uptake value (SUV) and metabolic tumor volume (MTV) with survival endpoints were explored. Multivariate analysis was performed using Cox proportional hazard. RESULTS: The median MTV, SUV, and gross tumor volume, as delineated using the 50% SUVmax threshold, were 366 cc (range, 0-3,567 cc), 8.1 (range, 0-25), and 48.5 cc (range, 1-190 cc), respectively. On univariate analysis, both MTVs (as measured as a continuous variable and using the median value of 266 cc as cutoff) were predictive of decreased overall survival (P < 0.05 for both). A strong trend toward decreased progression-free survival (P = 0.05), in-field control (P = 0.06), and locoregional control (P = 0.07) was also observed with increasing MTV when analyzed as a continuous variable. Multi variate analysis confirmed MTV as an independent predictor of mortality. CONCLUSION: The PET-derived parameter MTV may serve as a potentially valuable factor for risk stratification and for guiding treatment in future reirradiation trials. LEVEL OF EVIDENCE: 4.

AB - AIM: This study was done to explore team member's perception regarding impediments to the care of patients with heart failure (HF). BACKGROUND: Complex, chronic HF patients require interprofessional teams to address their multiple health needs. Working in a team has some challenges in achieving goals. Sociocultural differences in Iranian therapeutic team members causes some impediments to provide effective care in the form of a team. METHODS: Data were collected through unstructured in-depth interviews with 58 team members in caring for the patients with HF. The interviews were transcribed verbatim and analyzed using content analysis. RESULTS: Twelve subcategories and 5 categories were formed: inefficient supportive network, inadequacy of training and treatment, affectability and variability challenges for the team, arduous working conditions, and heavy physicians shadow on nursing. The final theme emerged as "Invisible cobwebs in teamwork." CONCLUSION: Despite teamwork being an efficient way of achieving goals, several impediments like a cobweb hinder it from becoming fully exploited. Teamwork has a desirable output when all the members feel the same sense of authority and see themselves in an integrated team and managers have a crucial role in removing these impediments.

PMID- 29573281 TI - Surviving neoliberalism, maintaining values: Community health mergers in Victoria, Australia. AB - PURPOSE: Independent, not-for-profit community health services in the state of Victoria, Australia, provide one of that country's few models of comprehensive primary health care (PHC). Recent amalgamations among some such agencies created regional-sized community health organisations, in a departure from this sector's traditionally small local structure. This study explored the motivations, desired outcomes, and decision-making process behind these mergers. METHODOLOGY: Qualitative exploratory study was based on 26 semistructured interviews with key informants associated with 2 community health mergers, which took place in 2014 in Victoria, Australia. Thematic data analysis was influenced by concepts derived from institutional theory. FINDINGS: Becoming bigger by merging was viewed as the best way to respond to mounting external pressures, such as increasingly neoliberal funding mechanisms, perceived as threatening survival. Desired outcomes were driven by comprehensive PHC values, and related to creating organisational capacity to continue providing quality services to disadvantaged communities. ORIGINALITY/VALUE: This study offers insights into decision-making processes geared towards protecting the comprehensiveness of PHC service delivery for disadvantaged communities, ensuring financial viability, and surviving neoliberal economic policy whilst preserving communitarian values. These are relevant to an international audience, within a global context of rising health inequities, increasingly tight fiscal environments, and growing neoliberal influences on health policymaking and funding.

AB - Polymers are usually considered as thermal insulators, and their applications are limited by their low thermal conductivity. However, recent studies have shown that certain polymers have surprisingly high thermal conductivity, some of which are comparable to that in poor metals or even silicon. Here, the experimental achievements and theoretical progress of thermal transport in polymers and their nanocomposites are outlined. The open questions and challenges of existing theories are discussed. Special attention is given to the mechanism of thermal transport, the enhancement of thermal conductivity in polymer nanocomposites/fibers, and their potential application as thermal interface materials.

PMID- 29573284 TI - Materials for Neural Differentiation, Trans-Differentiation, and Modeling of Neurological Disease. AB - Neuron regeneration from pluripotent stem cells (PSCs) differentiation or somatic cells trans-differentiation is a promising approach for cell replacement in neurodegenerative diseases and provides a powerful tool for investigating neural development, modeling neurological diseases, and uncovering the mechanisms that underlie diseases. Advancing the materials that are applied in neural differentiation and trans-differentiation promotes the safety, efficiency, and efficacy of neuron regeneration. In the neural differentiation process, matrix materials, either natural or synthetic, not only provide a structural and biochemical support for the monolayer or three-dimensional (3D) cultured cells but also assist in cell adhesion and cell-to-cell communication. They play important roles in directing the differentiation of PSCs into neural cells and modeling neurological diseases. For the trans-differentiation of neural cells, several materials have been used to make the conversion feasible for future therapy. Here, the most current applications of materials for neural differentiation for PSCs, neuronal trans-differentiation, and neurological disease modeling is summarized and discussed. PMID- 29573286 TI - Self-Reporting Fiber-Reinforced Composites That Mimic the Ability of Biological Materials to Sense and Report Damage. AB - Sensing of damage, deformation, and mechanical forces is of vital importance in many applications of fiber-reinforced polymer composites, as it allows the structural health and integrity of composite components to be monitored and microdamage to be detected before it leads to catastrophic material failure. Bioinspired and biomimetic approaches to self-sensing and self-reporting materials are reviewed. Examples include bruising coatings and bleeding composites based on dye-filled microcapsules, hollow fibers, and vascular networks. Force-induced changes in color, fluorescence, or luminescence are achieved by mechanochromic epoxy resins, or by mechanophores and force-responsive proteins located at the interface of glass/carbon fibers and polymers. Composites can also feel strain, stress, and damage through embedded optical and electrical sensors, such as fiber Bragg grating sensors, or by resistance measurements of dispersed carbon fibers and carbon nanotubes. Bioinspired composites with the ability to show autonomously if and where they have been damaged lead to a multitude of opportunities for aerospace, automotive, civil engineering, and wind turbine applications. They range from safety features for the detection of barely visible impact damage, to the real-time monitoring of deformation of load-bearing components. PMID- 29573287 TI - Self-Powered Wearable Electronics Based on Moisture Enabled Electricity Generation. AB - Most state-of-the-art electronic wearable sensors are powered by batteries that require regular charging and eventual replacement, which would cause environmental issues and complex management problems. Here, a device concept is reported that can break this paradigm in ambient moisture monitoring-a new class of simple sensors themselves can generate moisture-dependent voltage that can be used to determine the ambient humidity level directly. It is demonstrated that a moisture-driven electrical generator, based on the diffusive flow of water in titanium dioxide (TiO2 ) nanowire networks, can yield an output power density of up to 4 uW cm-2 when exposed to a highly moist environment. This performance is two orders of magnitude better than that reported for carbon-black generators. The output voltage is strongly dependent on humidity of ambient environment. As a big breakthrough, this new type of device is successfully used as self-powered wearable human-breathing monitors and touch pads, which is not achievable by any existing moisture-induced-electricity technology. The availability of high-output self-powered electrical generators will facilitate the design and application of a wide range of new innovative flexible electronic devices.

PMID- 29573289 TI - Electrocatalytic Hydroxylation of Sterols by Steroid C25 Dehydrogenase from Sterolibacterium denitrificans. AB - The electrochemically driven catalysis of the complex molybdoenzyme steroid C25 dehydrogenase (S25DH) from the beta-Proteobacterium Sterolibacterium denitrificans is reported. S25DH catalyses the oxygen-independent regioselective hydroxylation of the tertiary C25 atom of sterols and also their derivatives. Cholest-4-en-3-one is a native substrate for S25DH, which produces 25 hydroxycholest-4-en-3-one as a product of catalytic turnover. Cholecalciferol (vitD3 ) is also a substrate. S25DH was immobilised on a modified gold working electrode with the co-adsorbent chitosan. The complexes ferricyanide ([Fe(CN)6 ]3 ) and ferrocenium methanol (FM+ ) are effective artificial electron acceptors from S25DH and act as mediators of electron transfer between the electrode and the enzyme. 2-Hydroxypropyl-beta-cyclodextrin (HPCD) was employed as a sterol solubiliser, in addition to 2-methoxyethanol. The catalytic activity varied, depending upon the concentration of solubiliser in the reaction mixture. Parallel studies with [Fe(CN)6 ]3- as a chemical (as opposed to electrochemical) oxidant coupled to HPLC analysis show that S25DH is capable of oxidising both vitD3 and its less stable isomer, pre-vitD3 , and that the former substrate is stabilised by HPCD. PMID- 29573290 TI - Intercalated Water and Organic Molecules for Electrode Materials of Rechargeable Batteries. AB - The intrinsic limitations of lithium-ion batteries (LIBs) with regard to safety, cost, and the availability of raw materials have promoted research on so-called "post-LIBs". The recent intense research of post-LIBs provides an invaluable lesson that existing electrode materials used in LIBs may not perform as well in post-LIBs, calling for new material designs compliant with emerging batteries based on new chemistries. One promising approach in this direction is the development of materials with intercalated water or organic molecules, as these materials demonstrate superior electrochemical performance in emerging battery systems. The enlarged ionic channel dimensions and effective shielding of the electrostatic interaction between carrier ions and the lattice host are the origins of the observed electrochemical performance. Moreover, these intercalants serve as interlayer pillars to sustain the framework for prolonged cycles. Representative examples of such intercalated materials applied to batteries based on Li+ , Na+ , Mg2+ , and Zn2+ ions and supercapacitors are considered, along with their impact in materials research. PMID- 29573291 TI - Digital analysis yields more reliable and accurate measures of dermal and epidermal thickness in histologically processed specimens compared to traditional methods. AB - Changes in the thickness of the dermis and epidermis have been described in the scenario of tissue expansion as well as inflammatory skin processes (psoriasis, contact hypersensitivity and so on). These changes have previously been quantified using ocular micrometers to obtain and then average a limited number of spot measurements, leading to suboptimal accuracy. We describe a rapid method of using freely available ImageJ software to analyze digitized images of fixed skin specimens. By determining the cross-sectional area and surface length of a skin layer, a simple calculation produces more accurate and reproducible measurements of its thickness compared to historical methods, with excellent inter-rater reliability.

PMID- 29573293 TI - Reconfigurable Printed Liquids. AB - Liquids lack the spatial order required for advanced functionality. Interfacial assemblies of colloids, however, can be used to shape liquids into complex, 3D objects, simultaneously forming 2D layers with novel magnetic, plasmonic, or structural properties. Fully exploiting all-liquid systems that are structured by their interfaces would create a new class of biomimetic, reconfigurable, and responsive materials. Here, printed constructs of water in oil are presented. Both form and function are given to the system by the assembly and jamming of nanoparticle surfactants, formed from the interfacial interaction of nanoparticles and amphiphilic polymers that bear complementary functional groups. These yield dissipative constructs that exhibit a compartmentalized response to chemical cues. Potential applications include biphasic reaction vessels, liquid electronics, novel media for the encapsulation of cells and active matter, and dynamic constructs that both alter, and are altered by, their external environment. PMID- 29573294 TI - Anti-inflammatory therapy with tumour necrosis factor inhibitors is associated with reduced risk of major adverse cardiovascular events in psoriasis. AB - BACKGROUND: Psoriasis is a systemic chronic inflammatory condition associated with increased risk of cardiovascular disease. Data demonstrating that decreased skin inflammation reduces cardiovascular events in patients with psoriasis may be generalizable to other chronic inflammatory states with heightened cardiovascular risk. OBJECTIVE: To determine whether tumour necrosis factor inhibitor (TNFi) therapy is associated with decreased major adverse cardiovascular events (MACE) in patients with psoriasis. METHODS: In this retrospective cohort study using the KPSC health plan, patients had at least three ICD-9 codes for psoriasis and no antecedent MACE codes. Propensity score-adjusted multivariable Cox regression assessed hazard ratios (HR) of MACE associated with TNFi use. RESULTS: After adjusting for cardiovascular risk factors, the TNFi cohort had significantly lower MACE HR compared with the topical cohort (HR, 0.80; 95% CI, 0.66-0.98). The oral/phototherapy cohort had similar MACE HR compared with the topical cohort (HR, 1.19 (95% CI, 0.99-1.42)). CONCLUSIONS: We observed significantly lower MACE risk in patients with psoriasis receiving TNFi compared to topical or oral/phototherapy agents. TNFi therapy may have benefits beyond skin disease in mitigating cardiovascular event risk. PMID- 29573295 TI - Enrichment of Precious Metals from Wastewater with Core-Shell Nanoparticles of Iron. AB - Large-scale deployment of zero-valent iron nanoparticles for enrichment and recovery of gold from industrial wastewater is reported. Iron nanoparticles have a core-shell structure in which a metallic iron core is enclosed with a thin layer of iron oxides/hydroxides. The two nanocomponents offer synergistic functions for rapid separation, enrichment, and stabilization of metal ions such as Au, Ag, Ni, and Cu. Thanks to the advantages of small size, large surface area, and high reactivity, only a small amount of iron nanoparticles are needed. The recovered nanoparticles thus contain precious metals well above conventional metal ores (e.g., >100 g Au ton-1 ). Cost-effective recovery of precious metals from trace-level sources such as wastewater looks promising. PMID- 29573296 TI - Large-Scale Synthesis and Medical Applications of Uniform-Sized Metal Oxide Nanoparticles. AB - Thanks to recent advances in the synthesis of high-quality inorganic nanoparticles, more and more types of nanoparticles are becoming available for medical applications. Especially, metal oxide nanoparticles have drawn much attention due to their unique physicochemical properties and relatively inexpensive production costs. To further promote the development and clinical translation of these nanoparticle-based agents, however, it is highly desirable to reduce unwanted interbatch variations of the nanoparticles because characterizing and refining each batch are costly, take a lot of effort, and, thus, are not productive. Large-scale synthesis is a straightforward and economic pathway to minimize this issue. Here, the recent achievements in the large-scale synthesis of uniform-sized metal oxide nanoparticles and their biomedical applications are summarized, with a focus on nanoparticles of transition metal oxides and lanthanide oxides, and clarifying the underlying mechanism for the synthesis of uniform-sized nanoparticles. Surface modification steps to endow hydrophobic nanoparticles with water dispersibility and biocompatibility are also briefly described. Finally, various medical applications of metal oxide nanoparticles, such as bioimaging, drug delivery, and therapy, are presented. PMID- 29573297 TI - A simple and fast quantitative analysis of quinolizidine alkaloids and their biosynthetic precursor, lysine, in Sophora alopecuroides by hydrophilic interaction chromatography coupled with triple-quadrupole tandem mass spectroscopy. AB - INTRODUCTION: Different parts of Sophora alopecuroides L. (Fabaceae) have historically been used in traditional Chinese medicine for the treatment of dysentery and enteritis. This plant is also utilised as an important resource for industrial preparation of quinolizidine alkaloidal pharmaceuticals. OBJECTIVE: Establish a reliable, simple and fast analytical method for the quantitative determination of the quinolizidine-type alkaloids and extend understanding of the metabolism of quinolizidine-type alkaloids in S. alopecuroides. METHODS: Hydrophilic interaction chromatography coupled with triple-quadrupole tandem mass spectrometry (HILIC-TQ-MS/MS) in multiple-reaction monitoring (MRM) mode were used to determine seven quinolizidine-type alkaloids and their biosynthetic precursor, lysine, in S. alopecuroides. RESULTS: A good separation was obtained on an ultra high-performance liquid chromatography (UHPLC) amide column within 7 min. The overall limits of detection (LODs) were between 1.13 and 2.81 ng/ml, and limits of quantitation (LOQs) were between 3.80 and 8.48 ng/ml. The developed method was successfully applied to 21 samples of S. alopecuroides. The seeds had the highest concentration of alkaloids among the different plant parts. Oxymatrine and oxysophocarpine were the two most abundant alkaloids in all of the different parts and at different phenological growth stages. The contents of quinolizidine alkaloids showed correlations with lysine. CONCLUSION: A rapid and sensitive analytical method was established for the simultaneous determination of seven quinolizidine-type alkaloids and their biosynthetic precursor, lysine, in S. alopecuroides; the content of lysine may be used as a marker to predict alkaloid production. PMID- 29573298 TI - Anti-ageing effect of red ginseng revealed by urinary metabonomics using RRLC-Q TOF-MS. AB - INTRODUCTION: Red ginseng (RG) is one of the main processed products of the roots and rhizomes of Panax ginseng C.A. Meyer and is used for anti-ageing. But how metabonomic influences of RG on the progress of ageing are less researched. OBJECTIVE: A metabonomic method was developed to study the characters of the ageing process and the effects of total ginsenosides of red ginseng (TGRG) on the progress of ageing. METHODS: Urine samples from four different ages (4, 12, 18 and 24 months old) of rats and interference after TGRG were analysed by rapid resolution liquid chromatography coupled with quadruple-time-of-flight mass spectrometry (RRLC-Q-TOF-MS) and multivariate statistical analysis were performed for the pattern recognition and characteristic metabolites identification. RESULTS: Fourteen potential biomarkers were found and identified by MS/MS analysis by referring to authentic chemicals. The analysis of metabolic pathways indicated that the reduced energy and lipid metabolism, the decline of kidney function and amino acids metabolism disorders were the main features of ageing. After TGRG administration, lipid and amino acids metabolism of 18 and 24 month old rats were adjusted to restore a younger level, and nine related biomarkers in the ageing process reset to a younger level were recognised. CONCLUSION: These changes showed that TGRG may produce an anti-ageing effect by intervening in the lipid metabolism and correcting the amino acid metabolism disorders in ageing rats. PMID- 29573300 TI - Synthesis and Structure of a Stable Bis(methylene)-lambda4 -sulfane. AB - Bis(methylene)-lambda4 -sulfane 1, a >C=S=C< heterocumulene, was obtained as a red crystalline solid from the reaction between elemental sulfur and a carbenoid that contains sterically demanding silylalkyl groups. Under atmospheric conditions, and even at elevated temperatures, 1 exhibits extraordinary stability. The molecular structure and electron-density distribution of 1 were analyzed by single-crystal X-ray diffraction analysis, which revealed a bent C=S=C geometry with C=S=C pi-bonds. These results, combined with those of variable-temperature NMR measurements and theoretical calculations suggest a slow rotation of the S=C moieties in 1, the stability and structure of which were further examined by theoretical calculations. PMID- 29573299 TI - Revealing the Contribution of Individual Factors to Hydrogen Evolution Reaction Catalytic Activity. AB - For the electrochemical hydrogen evolution reaction (HER), the electrical properties of catalysts can play an important role in influencing the overall catalytic activity. This is particularly important for semiconducting HER catalysts such as MoS2 , which has been extensively studied over the last decade. Herein, on-chip microreactors on two model catalysts, semiconducting MoS2 and semimetallic WTe2 , are employed to extract the effects of individual factors and study their relations with the HER catalytic activity. It is shown that electron injection at the catalyst/current collector interface and intralayer and interlayer charge transport within the catalyst can be more important than thermodynamic energy considerations. For WTe2 , the site-dependent activities and the relations of the pure thermodynamics to the overall activity are measured and established, as the microreactors allow precise measurements of the type and area of the catalytic sites. The approach presents opportunities to study electrochemical reactions systematically to help establish rational design principles for future electrocatalysts. PMID- 29573301 TI - Early death and causes of death of people with Down syndrome: A systematic review. AB - BACKGROUND: It is thought that people with Down syndrome die younger than the general population, but that survival rates are improving. METHODS: Five databases were searched for keywords related to intellectual disabilities, Down syndrome and mortality. Strict inclusion criteria were applied. Information from 34 selected studies was tabulated, extracted and synthesized. RESULTS: People with Down syndrome died about 28 years younger than the general population. Congenital heart anomalies, comorbidities, low birthweight, and Black and minority ethnicity influenced earlier age of death, as did younger maternal age and poorer parental education. Congenital heart anomalies and respiratory conditions were the leading causes of death, and more common than in the general population. Survival rates have improved over time, particularly for those with congenital heart anomalies. CONCLUSIONS: People with Down syndrome are living longer but still die younger of different causes than the general population. More robust comparative data are needed, and ethnic differences require further study. PMID- 29573302 TI - Human herpesvirus portal proteins: Structure, function, and antiviral prospects. AB - Herpesviruses (Herpesvirales) and tailed bacteriophages (Caudovirales) package their dsDNA genomes through an evolutionarily conserved mechanism. Much is known about the biochemistry and structural biology of phage portal proteins and the DNA encapsidation (viral genome cleavage and packaging) process. Although not at the same level of detail, studies on HSV-1, CMV, VZV, and HHV-8 have revealed important information on the function and structure of herpesvirus portal proteins. During dsDNA phage and herpesviral genome replication, concatamers of viral dsDNA are cleaved into single length units by a virus-encoded terminase and packaged into preformed procapsids through a channel located at a single capsid vertex (portal). Oligomeric portals are formed by the interaction of identical portal protein monomers. Comparing portal protein primary aa sequences between phage and herpesviruses reveals little to no sequence similarity. In contrast, the secondary and tertiary structures of known portals are remarkable. In all cases, function is highly conserved in that portals are essential for DNA packaging and also play a role in releasing viral genomic DNA during infection. Preclinical studies have described small molecules that target the HSV-1 and VZV portals and prevent viral replication by inhibiting encapsidation. This review summarizes what is known concerning the structure and function of herpesvirus portal proteins primarily based on their conserved bacteriophage counterparts and the potential to develop novel portal-specific DNA encapsidation inhibitors.

Understanding the unique characteristics of the fetal circulation and its differences from the postnatal system can aid the sonographer in identifying normal1 and anomalous2 anatomy (Figure 1). PMID- 29573304 TI - The challenge of discriminating between HIV-1, HIV-2 and HIV-1/2 dual infections. AB - OBJECTIVES: Discrimination between HIV-1 and HIV-2 is important to ensure appropriate antiretroviral treatment (ART) and epidemiological surveillance. However, serological tests have shown frequent mistyping when applied in the field. We evaluated two confirmatory tests, INNO-LIA HIV I/II Score and ImmunoComb HIV 1/2 BiSpot, for HIV type discriminatory capacity. METHODS: Samples from 239 ART-naive HIV-infected patients from the Bissau HIV Cohort in Guinea Bissau were selected retrospectively based on the initial HIV typing performed in Bissau, ensuring a broad representation of HIV types. INNO-LIA results were interpreted by the newest software algorithm, and three independent observers read the ImmunoComb results. HIV-1/HIV-2 RNA and DNA were measured for confirmation. RESULTS: INNO-LIA results showed 123 HIV-1 positive samples, 69 HIV 2 positive and 47 HIV-1/2 dually reactive. There was agreement between INNO-LIA and HIV-1/HIV-2 RNA and DNA detection, although not all HIV-1/2 dually reactive samples could be confirmed by the nucleic acid results. Overall, the observers found that the ImmunoComb results differed from the INNO-LIA results, with agreements of 90.4, 91.2 and 92.5%, respectively, for HIV-1, HIV-2 and HIV-1/2. The combined kappa-score for agreement between the three observers was 0.955 (z score 35.1; P < 0.01). Of the HIV-2 mono-reactive samples (INNO-LIA), the three observers interpreted 24.6-31.9% as HIV-1/2 dually infected by ImmunoComb. None of these samples had detectable HIV-1 RNA or DNA. CONCLUSIONS: There was accordance between INNO-LIA calls and nucleic acid results, whereas ImmunoComb overestimated the number of HIV-1/2 dually infected patients. Confirmatory typing is needed for patients diagnosed with HIV-1/2 dual infection by ImmunoComb. PMID- 29573305 TI - Accounting for disturbance history in models: using remote sensing to constrain carbon and nitrogen pool spin-up. AB - Disturbances such as wildfire, insect outbreaks, and forest clearing, play an important role in regulating carbon, nitrogen, and hydrologic fluxes in terrestrial watersheds. Evaluating how watersheds respond to disturbance requires understanding mechanisms that interact over multiple spatial and temporal scales. Simulation modeling is a powerful tool for bridging these scales; however, model projections are limited by uncertainties in the initial state of plant carbon and nitrogen stores. Watershed models typically use one of two methods to initialize these stores: spin-up to steady state or remote sensing with allometric relationships. Spin-up involves running a model until vegetation reaches equilibrium based on climate. This approach assumes that vegetation across the watershed has reached maturity and is of uniform age, which fails to account for landscape heterogeneity and non-steady-state conditions. By contrast, remote sensing, can provide data for initializing such conditions. However, methods for assimilating remote sensing into model simulations can also be problematic. They often rely on empirical allometric relationships between a single vegetation variable and modeled carbon and nitrogen stores. Because allometric relationships are species- and region-specific, they do not account for the effects of local resource limitation, which can influence carbon allocation (to leaves, stems, roots, etc.). To address this problem, we developed a new initialization approach using the catchment-scale ecohydrologic model RHESSys. The new approach merges the mechanistic stability of spin-up with the spatial fidelity of remote sensing. It uses remote sensing to define spatially explicit targets for one or several vegetation state variables, such as leaf area index, across a watershed. The model then simulates the growth of carbon and nitrogen stores until the defined targets are met for all locations. We evaluated this approach in a mixed pine dominated watershed in central Idaho, and a chaparral-dominated watershed in southern California. In the pine-dominated watershed, model estimates of carbon, nitrogen, and water fluxes varied among methods, while the target-driven method increased correspondence between observed and modeled streamflow. In the chaparral watershed, where vegetation was more homogeneously aged, there were no major differences among methods. Thus, in heterogeneous, disturbance-prone watersheds, the target-driven approach shows potential for improving biogeochemical projections. PMID- 29573306 TI - Involvement of microRNA miR-2b-3p in regulation of metabolic resistance to insecticides in Plutella xylostella. AB - The diamondback moth, Plutella xylostella, has developed extremely high levels of resistance to chlorantraniliprole and other classes of insecticides in the field. As microRNAs (miRNAs) play important roles in various biological processes through gene regulation, we examined the miRNA profile of P. xylostella in response to chlorantraniliprole exposure. RNA sequencing analysis showed that insecticide treatment caused significant changes in the abundance of some miRNAs. Increasing exposure time and insecticide concentration induced more dysregulated miRNAs in P. xylostella larvae. We also screened potential target genes for some of the differentially expressed miRNAs (such as miR-2b-3p, miR-14b-5p and let-7 5p), which may play important roles in insecticide resistance development. Exposure of P. xylostella larvae to chlorantraniliprole caused considerable overexpression in the transcript levels of potential target genes cytochrome P450 9f2 (CYP9F2) and 307a1 (CYP307a1). Application of miR-2b-3p and miR-14b-5p mimics significantly suppressed the relative transcript levels of CYP9F2 and CYP307a1, respectively, in a P. xylostella cell line. Furthermore, enrichment of P. xylostella diet with miR-2b-3p mimics significantly increased mortality in deltamethrin-resistant larvae when exposed to deltamethrin. The results suggest that miR-2b-3p may suppress CYP9F2 transcript levels in P. xylostella and consequently inhibit larval detoxification pathways. The findings provide an insight into possible role of miRNAs in regulation of metabolic resistance of insects to insecticides. PMID- 29573307 TI - Development of a cognitive behavioural therapy-based guided self-help intervention for adults with intellectual disability. AB - BACKGROUND: Despite strong evidence for cognitive behaviour therapy (CBT) in treating mental health, its use, thus far, has been limited for people with intellectual disabilities. This study describes a CBT-based guided self-help (CBT GSH) manual for individuals with intellectual disability, and focus groups explore the views of clinicians, therapists, support staff and managers. MATERIAL AND METHODS: Using a qualitative methodology, an expert team adapted the manual. Focus groups provided feedback, followed by thematic content analysis for modifications. RESULTS: Participants supported using the manual, with varying views about the delivery. Quality of relationships and competence of the administrator determined the best person to deliver the treatment. Heterogeneity in the intellectual disability population was a challenge to delivering manual based interventions. Participants made suggestions about language and organization. CONCLUSIONS: Amendments were made to the manual in line with expert feedback. An evaluation is warranted to test for feasibility, delivery, acceptability and efficacy.

AB - The development of synthetic tools to introduce saccharide derivatives into functionally complex molecules is of great interest, particularly in the field of drug discovery. Herein, we report a new route toward highly functionalized, arylated saccharides, which involves nickel-catalyzed cross-coupling of photoredox-generated saccharyl radicals with a range of aryl- and heteroaryl bromides, triggered by an organic photocatalyst. In contrast to existing methods, the mild reaction conditions achieve arylation of saccharide motifs while leaving the anomeric carbon available, thus providing access to a class of arylated glycosides that has been underexplored until now. To demonstrate the potential of this strategy in late-stage functionalization, a variety of structurally complex molecules incorporating saccharide moieties were synthesized. PMID- 29573309 TI - Survival of Mycobacterium avium subsp. paratuberculosis in the intermediate and final digestion products of biogas plants. AB - AIMS: To evaluate the survival of Mycobacterium avium subsp. paratuberculosis (MAP) during anaerobic digestion (AD), we studied two different biogas plants loaded with manure and slurry from paratuberculosis-infected dairy herds. METHODS AND RESULTS: Both plants were operating under mesophilic conditions, the first with a single digester and the second with a double digester. Mycobacterium avium subsp. paratuberculosis detection was performed by sampling each stage of the process, specifically the prefermenter, fermenter, liquid digestate and solid digestate stages, for 11 months. In both plants, MAP was isolated from the prefermenter stage. Only the final products, the solid and liquid digestates, of the one-stage plant showed viable MAP, while no viable MAP was detected in the digestates of the two-stage plant. CONCLUSIONS: Mycobacterium avium subsp. paratuberculosis showed a significant decrease during subsequent steps of the AD process, particularly in the two-stage plant. We suggest that the second digester maintained the digestate under anaerobic conditions for a longer period of time, thus reducing MAP survival and MAP load under the culture detection limit. SIGNIFICANCE AND IMPACT OF THE STUDY: Our data are unable to exclude the presence of MAP in the final products of the biogas plants, particularly those products from the single digester; therefore, the use of digestates as fertilizers is a real concern related to the possible environmental contamination with MAP. PMID- 29573310 TI - Standing genetic diversity and selection at functional gene loci are associated with differential invasion success in two non-native fish species. AB - Invasive species are expected to experience a unique combination of high genetic drift due to demographic factors while also experiencing strong selective pressures. The paradigm that reduced genetic diversity should limit the evolutionary potential of invasive species, and thus, their potential for range expansion has received little empirical support, possibly due to the choice of genetic markers. Our goal was to test for effects of genetic drift and selection at functional genetic markers as they relate to the invasion success of two paired invasive goby species, one widespread (successful) and one with limited range expansion (less successful). We genotyped fish using two marker types: single nucleotide polymorphisms (SNPs) in known-function, protein-coding genes and microsatellites to contrast the effects of neutral genetic processes. We identified reduced allelic variation in the invaded range for the less successful tubenose goby. SNPs putatively under selection were responsible for the observed differences in population structure between marker types for round goby (successful) but not tubenose goby (less successful). A higher proportion of functional loci experienced divergent selection for round goby, suggesting increased evolutionary potential in invaded ranges may be associated with round goby's greater invasion success. Genes involved in thermal tolerance were divergent for round goby populations but not tubenose goby, consistent with the hypothesis that invasion success for fish in temperate regions is influenced by capacity for thermal tolerance. Our results highlight the need to incorporate functional genetic markers in studies to better assess evolutionary potential for the improved conservation and management of species. PMID- 29573311 TI - Secular trends in opportunistic infections, cancers and mortality in patients with AIDS during the era of modern combination antiretroviral therapy. AB - OBJECTIVES: The aim of the study was to estimate the incidence of, determine risk factors for, and investigate the consequences of opportunistic infections (OIs) and malignancies among patients with the acquired immune deficiency syndrome (AIDS) in the era of modern combination antiretroviral therapy (cART). METHODS: Three enrolment periods (1998-2002, 2003-2005 and 2006-2012), corresponding to changes in predominant cART regimens, were compared among 1889 participants enrolled in a prospective cohort study, the Longitudinal Study of Ocular Complications of AIDS (LSOCA). Incidences of AIDS-related OIs and cancers were estimated. Multivariate logistic and Cox regression models were used to determine the effect of demographic and clinical characteristics on OIs and mortality. RESULTS: Between participants enrolled in the 1998-2002 and 2006-2012 enrolment periods, the incidence of OIs decreased from 27 per 1000 person-years (PY) to 11 per 1000 PY (P < 0.001), and mortality decreased from 41 per 1000 PY to 18 per 1000 PY (P < 0.0001), corresponding to improvements in cART regimens. CONCLUSIONS: Improvements in cART regimens led to a progressive decline in the incidence of OIs and mortality between 1999 and 2013 among patients with AIDS in the era of modern cART. PMID- 29573312 TI - Loss to follow-up and mortality among HIV-infected adolescents receiving antiretroviral therapy in Pune, India. AB - OBJECTIVES: India has the highest number of HIV-infected adolescents in Asia, but little is known about their treatment outcomes. We assessed rates and factors associated with loss to follow-up (LTFU) and mortality among Indian adolescents. METHODS: The analysis included adolescents (10-19 years old) starting antiretroviral therapy (ART) between 2005 and 2014 at BJ Government Medical College, Pune, India. LTFU was defined as missing more than three consecutive monthly visits. The competing-risks method was used to calculate subdistribution hazard ratios (SHRs) of predictors for LTFU, with death as the competing risk. Cox proportional hazard models were used to identify predictors of mortality. RESULTS: Of 717 adolescents starting ART, 402 with complete data were included in the analysis. Of these, 61% were male and 80% were perinatally infected, and the median baseline CD4 count was 174 cells/MUL. LTFU and mortality rates were 4.4 and 4.9/100-person years, respectively. Cumulative LTFU incidence increased from 6% to 15% over 6 years. Age >= 15 years [adjusted SHR (aSHR) 2.44; 95% confidence interval (CI) 1.18-5.02] was a risk factor for LTFU. Cumulative mortality increased from 9.5% to 17.9% over 6 years. World Health Organization (WHO) stages III and IV [adjusted hazard ratio (aHR) 2.26; 95% CI: 1.14-4.48] and an increase in CD4 count by 100 cells/MUL (aHR: 0.59; 95% CI: 0.43-0.83) were associated with mortality. CONCLUSIONS: A third of adolescents had been lost to follow-up or died by follow-up year 6. Older age was a risk factor for LTFU and advanced clinical disease for death. Strategies to improve retention counselling for older adolescents and closer clinical monitoring of all adolescents must be considered. PMID- 29573313 TI - Combined In Situ Illumination-NMR-UV/Vis Spectroscopy: A New Mechanistic Tool in Photochemistry. AB - Synthetic applications in photochemistry are booming. Despite great progress in the development of new reactions, mechanistic investigations are still challenging. Therefore, we present a fully automated in situ combination of NMR spectroscopy, UV/Vis spectroscopy, and illumination to allow simultaneous and time-resolved detection of paramagnetic and diamagnetic species. This optical fiber-based setup enables the first acquisition of combined UV/Vis and NMR spectra in photocatalysis, as demonstrated on a conPET process. Furthermore, the broad applicability of combined UVNMR spectroscopy for light-induced processes is demonstrated on a structural and quantitative analysis of a photoswitch, including rate modulation and stabilization of transient species by temperature variation. Owing to the flexibility regarding the NMR hardware, temperature, and light sources, we expect wide-ranging applications of this setup in various research fields. PMID- 29573314 TI - New cytochalasin from Rosellinia sanctae-cruciana, an endophytic fungus of Albizia lebbeck. AB - AIM: To explore the potential of Rosellinia sanctae-cruciana an endophytic fungus associated with Albizia lebbeck for pharmaceutically important cytotoxic compounds. METHODS AND RESULTS: One novel cytochalasin, named jammosporin A (1) and four known analogues (2-5) were isolated from the culture of the endophytic fungus R. sanctae-cruciana, harboured from the leaves of the medicinal plant A. lebbeck. Their structures were elucidated by extensive spectroscopic analyses including one-dimensional and two-dimensional nuclear magnetic resonance data along with MS data and by comparison with literature reports. In preliminary screening the ethyl acetate extract of the fungal culture was tested for cytotoxic activity against a panel of four cancer cell lines (MOLT-4, A549, MIA PaCa-2 and MDA-MB-231), and found to be active against MOLT-4 with an IC50 value of 10 MUg ml-1 . Owing to the remarkable cytotoxic activity of the extract the isolated compounds (1-5) were evaluated for their cytototoxicity against the MOLT 4 cell line by MTT assay. Interestingly, compounds 1-2, 4 and 5 showed considerable cytotoxic potential against the human leukaemia cancer cell line (MOLT-4) with IC50 values of 20.0, 10.0, 8.0 and 6.0 MUmol l-1 , respectively, while compound 3 showed an IC50 value of 25 MUmol l-1 . This is the first report of the existence of this class of secondary metabolites in R. sanctae-cruciana fungus. CONCLUSION: This study discovered a novel compound, named jammosporin A, isolated for the first time from R. sanctae-cruciana, an endophytic fungus of A. lebbeck with anticancer activity against the MOLT-4 cell line. SIGNIFICANCE AND IMPACT OF THE STUDY: Rosellinia sanctae-cruciana represents an interesting source of a new compound with bioactive potential as a therapeutic agent against a human leukaemia cancer cell line (MOLT-4). PMID- 29573315 TI - Photochemical Formation of Cyclobutane Pyrimidine Dimers in DNA through Electron Transfer from a Flanking Base. AB - Electron transfer (ET) to a pyrimidine base from external moieties is a common step involved in the quenching or repair of the cyclobutane pyrimidine dimer (CPD). In contrast, we present a pathway that is initiated by an ET from a flanking guanine base to a pyrimidine base, leading to the formation of a CPD. We studied a T5mCG sequence with a methylated cytosine and our results demonstrate that the pathway involves the formation of an exciplex and intersystem crossings. This pathway also provides an explanation for why the mutational hot spots are correlated with the methylated CpG sequences, which has been a significant issue in cancer research. PMID- 29573316 TI - Risk factors of adverse events in endoscopic retrograde cholangiopancreatography for patients aged >=85 years. AB - AIM: Little is known about the factors that contribute to the occurrence of adverse events in endoscopic retrograde cholangiopancreatography (ERCP) for people aged >=85 years and safety for the super-old. Therefore, we decided to identify these factors and to examine whether ERCP is safe in the super-old. METHODS: This was a single-center retrospective study. A total of 137 patients aged >=85 years who underwent therapeutic ERCP at Chiba University Hospital from January 2012 to March 2017 were retrospectively reviewed. RESULTS: Four cases of Billroth II reconstruction and two cases of gastrectomy with Roux-en-Y reconstruction were excluded, and 131cases in total were examined in the present study. A total of 10 and 121 cases with and without adverse events, respectively, were present. Using univariate analysis, factors significantly contributing to the occurrence of adverse events in therapeutic ERCP were identified as aged >=90 years (P = 0.0096), duodenal papilla cancer (P = 0.0012), gallbladder carcinoma (P = 0.023), and biliary metal stenting (P = 0.040). In multivariate analysis, only >=90 years-of-age was a significant factor (P = 0.049). In addition, comparison between 25 cases of the super-old and 106 cases aged 85-89 years was carried out. In the super-old group, the average value of the American Society of Anesthesiologists physical status classification and Charlson's Comorbidity Index were significantly better than those in 85-89-year-olds (P = 0.0035 and P < 0.0001, respectively). CONCLUSIONS: Although the super-old group had fewer comorbid diseases, they had significantly increased adverse events compared with patients aged 85-89 years. Geriatr Gerontol Int 2018; 18: 1038-1045. PMID- 29573317 TI - Oxygen uptake efficiency slope during exercise in adults with Down syndrome. AB - BACKGROUND: Persons with Down syndrome (DS) have low aerobic exercise capacity. The present authors sought to compare the oxygen uptake efficiency slope (OUES) between adults with and without DS performing graded exercise testing (GXT) and to investigate its relationship with peak oxygen uptake (VO2peak ) in both groups of participants. METHOD: Twenty-three participants with DS and 24 non-disabled controls performed GXT with VO2 measurements. OUES was calculated from data of the first 75%, 90% and 100% GXT time. Multiple linear regression analyses were computed to explore associations between the independent (OUES and DS) and the dependent variables (VO2peak ). RESULTS: VO2peak , GXT time and OUES were lower in participants with DS (p < .05). OUES and DS explained 69.3% of the variance in VO2peak . CONCLUSIONS: Our findings show that OUES values are lower in persons with DS. Additionally, it was shown that OUES has predictive value for VO2peak estimations in DS. PMID- 29573318 TI - Work scheme to isolate the different micro-organisms found in hydrogen-producing reactors: a study of effectiveness by pyrosequencing analysis. AB - AIM: The aim of this research was to create a work scheme for the isolation of the different micro-organisms commonly found in hydrogen-producing reactors and to test its effectiveness. METHODS AND RESULTS: Methods were selected to isolate anaerobic spore-forming fermenters, anaerobic fermenters that do not form spores, facultative aerobic fermenters and lactic acid bacteria. The methods were tested in two samples taken from a hydrogen-producing reactor fed with cheese whey. 16S rRNA gene sequences from isolates were compared with pyrosequencing analysis from the same samples. The isolates represented more than 88% of the abundance detected by pyrosequencing. Organisms from the genera Clostridium, Rahnella, Megasphaera, Lactobacillus, Propionibacterium, Bifidobacterium, Chryseobacterium and Acetobacter were isolated. Hydrogen-producing capacity was confirmed for the Clostridium, Rahnella and Megasphaera isolates. Coculture experiments indicate that Megasphaera prevented the total inhibition of Clostridium by Lactobacillus. CONCLUSION: The work scheme proposed was effective to isolate most of the micro organisms detected by pyrosequencing analysis. Physiological studies suggested a key role of Megasphaera. SIGNIFICANCE AND IMPACT OF THE STUDY: We showed the high culturability of the microbial communities from hydrogen-producing bioreactors. The isolates can be used to perform physiological studies to understand the H2 producing process. PMID- 29573319 TI - The Chemistry behind Catechol-Based Adhesion. AB - The adhesion of some marine organisms to almost any kind of surface in wet conditions has aroused increasing interest in recent decades. Numerous fundamental studies have been performed to understand the scientific basis of this behaviour, with catechols having been found to play a key role. Several novel bio-inspired adhesives and coatings with value-added performances have been developed by taking advantage of the knowledge gained from these studies. To date there has been no detailed overview focusing exclusively on the complex mode of action of these materials. The aim of this Review is to present recent investigations that elucidate the origin of the strong and versatile adsorption capacities of the catechol moiety and the effects of extrinsic factors that play important roles in the overall adhesion process, such as pH value, solvent, and the presence of metal ions. The aim is to detail the chemistry behind the astonishing properties of natural and synthetic catechol-based adhesive materials. PMID- 29573320 TI - Efficacy and tolerability of lamivudine plus dolutegravir as a switch strategy in a multicentre cohort of patients with suppressed HIV-1 replication. AB - OBJECTIVES: We evaluated the efficacy and tolerability of lamivudine + dolutegravir in a cohort of HIV-1 infected, treatment-experienced patients with undetectable HIV-RNA. METHODS: Time to treatment discontinuation (TD) and virological failure (VF) and their predictors were assessed in a multicenter cohort of HIV-1 infected patients, starting lamivudine + dolutegravir after reaching viral suppression. Secondary objective was the evaluation of changes in lipid profile, renal and immunological functions at week 48. RESULTS: We enrolled 206 patients (72.8% male, with 51 years median age), who mainly switched their antiretroviral therapy for simplification (32.5%) or drug toxicity (54.5%). The estimated probability of maintaining virological suppression at 48 and 96 weeks was 98.2% and 95.1%, respectively. VF was independently predicted by cumulative time on antiretroviral therapy. The estimated probability of remaining on lamivudine plus dolutegravir was 86.7% and 80.5% at week 48 and 96, respectively. A significant improvement in immunological function (CD4 count and CD4/CD8 ratio) was evidenced at week 48, as well as a decrease in total cholesterol/HDL ratio, triglycerides and estimated glomerular filtration rate. CONCLUSIONS: Lamivudine plus dolutegravir was effective in maintaining viral suppression in our cohort and led to an improvement in metabolic and immunologic functions. PMID- 29573321 TI - From Solute, Fluidic and Particulate Precursors to Complex Organizations of Matter. AB - The organization of matter from its constitutive units recruits intermediate states with distinctive degrees of self-association and molecular order. Existing as clusters, droplets, gels as well as amorphous and crystalline nanoparticles, these precursor forms have fundamental contributions towards the composition and structure of inorganic and organic architectures. In this personal account, we show that the transitions from atoms, molecules or ionic species to superstructures of higher order are intertwined with the interfaces and interactions of precursor and intermediate states. Structural organizations distributed across different length scales are explained by the multistep nature of nucleation and crystallization, which can be guided towards functional hybrid materials by the strategic application of additives, templates and reaction environments. Thus, the non-classical pathways for material formation and growth offer conceptual frameworks for elucidating, inducing and directing fascinating material organizations of biogenic and synthetic origins. PMID- 29573322 TI - Wearable Platform for Real-time Monitoring of Sodium in Sweat. AB - A fully integrated and wearable platform for harvesting and analysing sweat sodium concentration in real time during exercise has been developed and tested. The platform was largely produced using 3D printing, which greatly simplifies fabrication and operation compared to previous versions generated with traditional production techniques. The 3D printed platform doubles the capacity of the sample storage reservoir to about 1.3 ml, reduces the assembly time and provides simple and precise component alignment and contact of the integrated solid-state ion-selective and reference electrodes with the sorbent material. The sampling flowrate in the device can be controlled by introducing threads to enhance wicking of sweat from the skin, across the electrodes to the storage area. The platform was characterised in the lab and in exercise trials over a period of about 60 minutes continuous monitoring. Sweat sodium concentration was found to rise initially to approximately 17 mM and decline gradually over the period of the trial to about 11-12 mM. PMID- 29573323 TI - The interaction of the Chrna5 D398N variant with developmental nicotine exposure. AB - A single nucleotide polymorphism (SNP) in CHRNA5 (rs16969968, change from an aspartic acid [D] to asparagine [N] at position 398 of the human alpha5 nicotinic acetylcholine receptor subunit) has been associated with increased risk for nicotine dependence. Consequently, carriers of the risk variant may be at elevated risk for in utero nicotine exposure. To assess whether this gene environment interaction might impact nicotine intake in developmental nicotine exposed offspring, we utilized a mouse expressing this human SNP. D and N dams drank nicotine (100 MUg/mL) in 0.2% saccharin water or 0.2% saccharin water alone (vehicle) as their sole source of fluid from 30 days prior to breeding until weaning of offspring. The nicotine (D Nic, N Nic) or vehicle (D Veh, N Veh) exposed offspring underwent a 2-bottle choice test between postnatal ages of 30 to 46 days. N Nic offspring consumed the most nicotine at the highest concentration (400 MUg/mL) compared with all other groups. In contrast, D Nic offspring drank the least amount of nicotine at all concentrations tested. Nicotine-stimulated dopamine (DA) release measured from striatal synaptosomes was increased in D Nic offspring, while decreased in N Nic offspring relative to their genotype-matched controls. These data suggest that the alpha5 variant influences the effect of developmental nicotine exposure on nicotine intake of exposed offspring. This gene-environment interaction on striatal DA release may provide motivation for increased nicotine seeking in N Nic offspring and reduced consumption in D Nic offspring. PMID- 29573325 TI - Postharvest processing decreases the richness of bacterial taxa in the phyllosphere of broccoli. AB - AIMS: Diverse bacterial communities residing on the surfaces of fresh vegetables are important for food quality and safety; however, knowledge of the phyllosphere microbiota on fresh vegetables and of how it changes during postharvest stage is poorly understood. METHODS AND RESULTS: We used culturing to quantify bacterial abundance and 16S rRNA 454 pyrosequencing to analyse the bacterial community composition on broccoli florets collected from farms (preharvest) and retail stores (postharvest). The bacterial community compositions of the preharvest and postharvest broccoli were significantly different. The number of non-Escherichia coli coliform bacteria (Hafnia sp. and Rahnella sp.) was higher in the postharvest broccoli than in the preharvest broccoli. Minor bacterial taxa at the phylum and genus levels had markedly disappeared in the postharvest broccoli, resulting in low bacterial species richness in the postharvest broccoli. CONCLUSIONS: The dominant bacterial taxa persist and prevail in the phyllosphere of broccoli during the postharvest stage. SIGNIFICANCE AND IMPACT OF THE STUDY: A popular crop of leafy vegetables, broccoli, is of great agricultural and nutritional importance. This study provides a detailed description of changes in the bacterial community of broccoli in harvest and storage. This study presents novel data on the impact of postharvest conditions on the bacterial populations on broccoli florets. PMID- 29573326 TI - Platelets loaded with liposome-encapsulated thrombin have increased coagulability. AB - : Essentials Platelet transfusions can have limited efficacy during hemorrhage associated with coagulopathy. Thrombin can be shielded by encapsulation into nanoliposomes and delivered to platelets ex vivo. Loading platelets with liposomal thrombin improved several aspects of platelet coagulability. Platelets loaded with liposomal thrombin can overcome some coagulopathic deficiencies in vitro. SUMMARY: Background Platelets are integral to clot formation and are often transfused to stop or prevent bleeding. However, transfusions of platelets are not always effective, particularly in the most severe cases of hemorrhage. Nanoparticle systems have been developed to mimic platelets but inherently lack important aspects of platelet function, which limits their potential effectiveness. Objectives Increasing the natural coagulability of transfusable platelets could increase their efficacy during treatment of severe hemorrhage. Thrombin is a potent platelet agonist that currently cannot be used intravenously because of the risk of thrombosis. We hypothesized that delivery of thrombin to ex vivo platelets via liposomal encapsulation would enable transfusable platelets to become more coagulable in response to platelet agonists. Methods Thrombin was encapsulated into nanoliposomes and delivered to platelets ex vivo. Platelet coagulability was measured by monitoring platelet activation, clot contraction, clot time and clot stability in several in vitro assays. These parameters were also measured under conditions where coagulation is compromised, including during acidosis, antiplatelet drugs, hemophilia A and trauma-induced coagulopathy. Results Liposomal thrombin was endocytosed and used by platelets ex vivo but was not secreted upon activation. These modified platelets became more sensitive and responsive to agonists and improved clotting time even under conditions that normally cause platelet dysfunction or have impaired coagulation. Conclusions Several aspects of platelet function were enhanced by ex vivo delivery of liposomal thrombin. PMID- 29573324 TI - The African turquoise killifish: A research organism to study vertebrate aging and diapause. AB - The African turquoise killifish has recently gained significant traction as a new research organism in the aging field. Our understanding of aging has strongly benefited from canonical research organisms-yeast, C. elegans, Drosophila, zebrafish, and mice. Many characteristics that are essential to understand aging for example, the adaptive immune system or the hypothalamo-pituitary axis-are only present in vertebrates (zebrafish and mice). However, zebrafish and mice live more than 3 years and their relatively long lifespans are not compatible with high-throughput studies. Therefore, the turquoise killifish, a vertebrate with a naturally compressed lifespan of only 4-6 months, fills an essential gap to understand aging. With a recently developed genomic and genetic toolkit, the turquoise killifish not only provides practical advantages for lifespan and longitudinal experiments, but also allows more systematic characterizations of the interplay between genetics and environment during vertebrate aging. Interestingly, the turquoise killifish can also enter a long-term dormant state during development called diapause. Killifish embryos in diapause already have some organs and tissues, and they can last in this state for years, exhibiting exceptional resistance to stress and to damages due to the passage of time. Understanding the diapause state could give new insights into strategies to prevent the damage caused by aging and to better preserve organs, tissues, and cells. Thus, the African turquoise killifish brings two interesting aspects to the aging field-a compressed lifespan and a long-term resistant diapause state, both of which should spark new discoveries in the field. PMID- 29573327 TI - Imaging of non-accidental injury; what is clinical best practice? AB - Non-accidental injury (NAI) remains the leading cause of morbidity and mortality in children. Fractures are the second most common findings of NAI, after cutaneous lesions such as bruises and contusions. Imaging in NAI remains a controversial issue with little agreement concerning how, when and what imaging modalities should be used in the investigation of suspected cases. This review addresses the radiological investigations and findings of NAI, and the differential diagnoses of these findings. Adherence to the international guidelines for skeletal survey imaging is recommended. This ensures the content and quality of the radiographic series are of an optimal standard to improve the detection of occult fractures, and ensuring the accurate reporting of images. The involvement of a paediatric radiologist is important, if not essential in the diagnosis of NAI. In the evaluation of suspected cases, the role of the radiologist includes the detection of radiological findings suggestive of NAI, and the differentiation of these findings from normal variants and underlying pathologies. The diagnosis of NAI relies not only on radiological imaging, but also a combination of clinical and social findings. It is mandatory that all physicians work in close collaboration to improve diagnostic accuracy, as failure to diagnose NAI carries significant risk for morbidity. PMID- 29573328 TI - Kidney transplant graft outcomes in 379 257 recipients on 3 continents. AB - Kidney transplant outcomes that vary by program or geopolitical unit may result from variability in practice patterns or health care delivery systems. In this collaborative study, we compared kidney graft outcomes among 4 countries (United States, United Kingdom, Australia, and New Zealand) on 3 continents. We analyzed transplant and follow-up registry data from 1988-2014 for 379 257 recipients of first kidney-only transplants using Cox regression. Compared to the United States, 1-year adjusted graft failure risk was significantly higher in the United Kingdom (hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.18-1.26, P < .001) and New Zealand (hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.14 1.46, P < .001), but lower in Australia (HR 0.90, 95% CI 0.84-0.96, P = .001). In contrast, long-term adjusted graft failure risk (conditional on 1-year function) was significantly higher in the United States compared to Australia, New Zealand, and the United Kingdom (HR 0.74, 0.75, and 0.74, respectively; each P < .001). Thus long-term kidney graft outcomes are approximately 25% worse in the United States than in 3 other countries with well-developed kidney transplant systems. Case mix differences and residual confounding from unmeasured factors were found to be unlikely explanations. These findings suggest that identification of potentially modifiable country-specific differences in care delivery and/or practice patterns should be sought.

PMID- 29573331 TI - Facile Ionic Liquid-Assisted Strategy for Direct Precipitation of Eu2+ -Activated Nanophosphors under Ambient Conditions. AB - This work describes a novel ionic liquid (IL)-assisted synthesis strategy for a direct and easy production of Eu2+ -doped nanoparticles (NPs), where ILs are also used as fluoride sources to avoid the use of elemental fluorine or toxic hydrofluoric acid. Up to now, the direct synthesis of Eu2+ -doped nanophosphors consisted of an enormous challenge, due to the oxidation to Eu3+ observed in hydrous solution, which is commonly used for the preparation of NPs, generating lattice defects and undesired particle growth or agglomeration by additional reducing steps at high temperatures. In contrast, ILs, unless containing ClO4- or NO3- anions, do not present an oxidizing character, allowing the direct precipitation of NPs, e.g., using Eu2+ containing starting materials. Here, the undoped and Eu2+ -doped BaFCl NPs have been prepared under atmospheric conditions for the first time using ILs as solvents and also as fluoride source, applying sonochemical and microwave-assisted approaches. In general, this method bears an enormous potential for an easy synthesis of fluoride materials compared to inconvenient solid-state methods. In addition, the IL plays the role of a strongly attached protecting shell which represents ~7-8% of the total NPs weight. PMID- 29573332 TI - Epidemiology of multiple myeloma in 17 Latin American countries: an update. AB - The objective of this study was to describe incidence, mortality rates, and trends for multiple myeloma (MM) in Latin America (LA), contributing to better knowledge on the epidemiology of MM in this continent. Incidence data were extracted from the International Agency for Research on Cancer (IARC), for the period 1990-2007. Mortality data were obtained for 17 countries from the World Health Organization, for the period 1995-2013. Annual average percentage change (AAPC) and 95% confidence interval (95% CI) were calculated for incidence and mortality. The average incidence rate of MM was higher in Cali (Colombia). For the age-group over 60 years old, rates were 14.2 and 12.8 per 100,000 inhabitants for men and women, respectively. Increasing incidence trends were verified for Cali (Colombia). Mortality rates were higher among men; most countries presented increasing trends, and the highest increments were observed in Guatemala (12.5% [95% CI: 10.6; 14.5] in men; 8.8% [95% CI: 7.8; 9.8] in women), Ecuador (5.5% [95% CI: 5.0; 6.0] in men; 3.7 [95% CI: 3.1; 4.3] in women), Paraguay (2.9% [95% CI: 2.3; 3.5] in men; 3.2% [95% CI: 2.1; 4.3] in women), and Brazil (1.4% [95% CI: 1.3; 1.5] in men; 0.9% [95% CI: 0.8; 1.0] in women). Multiple myeloma presented heterogeneous incidence patterns in Cali (Colombia), Quito (Ecuador), and Costa Rica. Increasing mortality trends were verified for most Latin American countries and could be related to limited access to diagnosis and new therapies. PMID- 29573333 TI - Self-care among older people living with chronic conditions. AB - PURPOSE: The aim of this study was to clarify the concept of self-care among older people living with chronic health conditions. This concept clarification will assist nurses in addressing self-care among older people through research, policy and practice in offering an expanded conceptual model. BACKGROUND: Several policy influences over the past decade directly relate to the increased importance and economic necessity to require self-directed care for older people living with chronic health conditions to maintain their care at home in the community. METHOD: A selective review of literature on the concept of self-care included 31 sources. The Norris Concept Clarification method (1982) was used for clarification. The phenomenon is described historically according to its antecedents, attributes and consequences. RESULTS: A proposed definition is provided based on the clarification of this concept. A conceptual model is presented through an ecological framework. Self-care among older people living with chronic conditions is multidimensional and has multilevel influences (individual, community, system levels) and is mediated by the contexts and processes of ageing. Self-care originates along one's life course and is learned. Self-care responses are based on care needs when living with chronic health conditions. CONCLUSION: Self-care is an individual capacity, disposition and activity older people manifest in living with multiple chronic conditions. These features (capacity, disposition, action) influence one another and are hierarchical and continuous. Research, practice and policies that promote self care among older people can focus on these features to improve health outcomes and promote new models of care consistent with personal development and chronic care needs in older age. IMPLICATIONS FOR PRACTICE: This concept clarification can offer a model to support self-care among older people living with chronic conditions.

AB - : Essentials Cancer patients receiving anticoagulants for venous thromboembolism have an elevated bleeding risk. This secondary analysis of CATCH assessed characteristics of clinically relevant bleeding (CRB). CRB occurs in 15% of cancer patients with thrombosis using therapeutic doses of anticoagulation. After multivariate analysis, risk factors for CRB were age >75 years and intracranial malignancy. SUMMARY: Background Cancer patients with acute venous thromboembolism (VTE) receiving anticoagulant treatment have an increased bleeding risk. Objectives We performed a prespecified secondary analysis of the randomized, open label, Phase III CATCH trial (NCT01130025) to assess the rate and sites of and the risk factors for clinically relevant bleeding (CRB). Patients/Methods Patients with active cancer and acute, symptomatic VTE received either tinzaparin 175 IU kg-1 once daily or warfarin (target International Normalized Ratio [INR] of 2.0-3.0) for 6 months. Fisher's exact test was used to screen prespecified clinical risk factors; those identified as being significantly associated with an increased risk of CRB then underwent competing risk regression analysis of time to first CRB. Results Among 900 randomized patients, 138 (15.3%) had 180 CRB events. CRB occurred in 60 patients (81 events) in the tinzaparin group and in 78 patients (99 events) in the warfarin group (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.45-0.89). Common bleeding sites were gastrointestinal (36.7%; n = 66), genitourinary (22.8%; n = 41), and nasal (10.0%; n = 18). In multivariate analysis, the risk of CRB increased with age > 75 years (HR 1.83, 95% CI 1.14-2.94) and intracranial malignancy (HR 1.97, 95% CI 1.07-3.62). In the warfarin group, 40.4% of CRB events occurred in patients with with an INR of < 3.0. A lower time in therapeutic range was associated with a higher risk of CRB. Conclusions CRB is a frequent complication in cancer patients with VTE during anticoagulant treatment, and is associated with age > 75 years and intracranial malignancy. PMID- 29573334 TI - FGFR2 amplification is predictive of sensitivity to regorafenib in gastric and colorectal cancers in vitro. AB - Although regorafenib has demonstrated survival benefits in patients with metastatic colorectal and gastrointestinal stromal tumors, no proven biomarker has been identified for predicting sensitivity to regorafenib. Here, we investigated preclinical activity of regorafenib in gastric and colorectal cancer cells to identify genetic alterations associated with sensitivity to regorafenib. Mutation profiles and copy number assays of regorafenib target molecules indicated that amplification of fibroblast growth factor receptor 2 (FGFR2) was the only genetic alteration associated with in vitro sensitivity to regorafenib. Regorafenib effectively inhibited phosphorylation of FGFR2 and its downstream signaling molecules in a dose-dependent manner and selectively in FGFR2-amplified cells. Regorafenib induced G1 arrest (SNU-16, KATO-III) and apoptosis (NCI-H716); however, no significant changes were seen in cell lines without FGFR2 amplification. In SNU-16 mice xenografts, regorafenib significantly inhibited tumor growth, proliferation, and FGFR signaling compared to treatment with control vehicle. Regorafenib effectively abrogates activated FGFR2 signaling in FGFR2-amplified gastric and colorectal cancer and, therefore, might be considered for integration into treatment in patients with FGFR2-amplified gastric and colorectal cancers. PMID- 29573335 TI - Posttransplant reduction in preexisting donor-specific antibody levels after belatacept- versus cyclosporine-based immunosuppression: Post hoc analyses of BENEFIT and BENEFIT-EXT. AB - BENEFIT and BENEFIT-EXT were phase III studies of cytotoxic T-cell crossmatch negative kidney transplant recipients randomized to belatacept more intense (MI) based, belatacept less intense (LI)-based, or cyclosporine-based immunosuppression. Following study completion, presence/absence of HLA-specific antibodies was determined centrally via solid-phase flow cytometry screening. Stored sera from anti-HLA-positive patients were further tested with a single antigen bead assay to determine antibody specificities, presence/absence of donor specific antibodies (DSAs), and mean fluorescent intensity (MFI) of any DSAs present. The effect of belatacept-based and cyclosporine-based immunosuppression on MFI was explored post hoc in patients with preexisting DSAs enrolled to BENEFIT and BENEFIT-EXT. In BENEFIT, preexisting DSAs were detected in 4.6%, 4.9%, and 6.3% of belatacept MI-treated, belatacept LI-treated, and cyclosporine treated patients, respectively. The corresponding values in BENEFIT-EXT were 6.0%, 5.7%, and 9.2%. In both studies, most preexisting DSAs were of class I specificity. Over the first 24 months posttransplant, a greater proportion of preexisting DSAs in belatacept-treated versus cyclosporine-treated patients exhibited decreases or no change in MFI. MFI decline was more apparent with belatacept MI-based versus belatacept LI-based immunosuppression in both studies and more pronounced in BENEFIT-EXT versus BENEFIT. Although derived post hoc, these data suggest that belatacept-based immunosuppression decreases preexisting DSAs more effectively than cyclosporine-based immunosuppression. PMID- 29573336 TI - Impact of Klebsiella pneumoniae in lower gastrointestinal tract diseases. AB - The 2016 Global Burden of Disease report by WHO revealed that diseases of the gastrointestinal tract (GIT) had one of the highest incidence rates worldwide. The plethora of factors that contribute to the development of GIT-related illnesses can be divided into genetic, environmental and lifestyle factors. Apart from that, the role that infectious agents play in the development of GIT diseases has piqued the interest of researchers worldwide. The human gut harbors approximately 1014 bacteria in it with increasing concentration toward the lower GIT. Among the various microbiota that colonize the human gut, Gram-negative bacteria have been most notoriously linked to GIT-related diseases such as inflammatory bowel disease (IBD) including Crohn's disease and ulcerative colitis and colorectal cancer (CRC). Some of the notable culprits that have been attributed to these diseases are Bacteroides fragilis, Fusobacterium nucleatum, Escherichia coli and Helicobacter pylori. However, studies in recent years are beginning to recognize a new player, Klebsiella pneumoniae (K. pneumoniae) in the causation and progression of GIT diseases. Once synonymous with infections and diseases of the upper respiratory tract, K. pneumoniae has now emerged as one of the pathogens commonly isolated from patients with GIT diseases. However, extensive studies attributing K. pneumoniae to GIT diseases, particularly that of CRC are scanty. Therefore, this review intends to shed light on the association of K. pneumoniae in gastrointestinal diseases such as Crohn's disease, ulcerative colitis as well as CRC. PMID- 29573337 TI - Flow cytometric osmotic fragility test and eosin-5'-maleimide dye-binding tests are better than conventional osmotic fragility tests for the diagnosis of hereditary spherocytosis. AB - INTRODUCTION: Hereditary spherocytosis (HS) is the most common inherited hemolytic anemia with heterogeneous clinico-laboratory manifestations. We evaluated the flow-cytometric tests: eosin-5'-maleimide (EMA) and flow-cytometric osmotic fragility test (FOFT) and the conventional osmotic fragility tests (OFT) for the diagnosis of hereditary spherocytosis (HS). METHODS: One hundred two suspected HS patients underwent EMA, FOFT, incubated OFT (IOFT), and room temperature OFT (RT-OFT). In addition, 10 cases of immune hemolytic anemia (IHA) were included, and performance of the above 4 tests was evaluated. For EMA and FOFT, 5 normal controls were assessed together with the patients and cutoffs were calculated using receiver-operator-characteristics curve (ROC) analysis. RESULTS: The best cutoff for %EMA decrease was 12.5%, and for FOFT, %residual red cells (%RRC) was 25.6%. The sensitivity and specificity of RT-OFT was 62.06% and 86.3%, respectively, while that of IOFT was 79.31% and 87.67%, respectively. Both flow cytometric tests performed better. Sensitivity and specificity of EMA was 86.2% and 93.9% respectively, and that of FOFT was 96.6% and 98.63%, respectively. The combination of the FOFT with IOFT or EMA dye-binding test yields a sensitivity of 100%, but with EMA, it had a higher specificity. Hb/MCHC was a predictor of the severity of the disease while %EMA decrease and %RRC did not correlate with severity of the disease. CONCLUSION: Flow-cytometric osmotic fragility test is the best possible single test followed by EMA for diagnosis of HS. A combination of FOFT and EMA can correctly diagnose 100% patients. These tests are likely to replace conventional OFTs in future. PMID- 29573338 TI - Nanodiamonds and Their Applications in Cells. AB - Diamonds owe their fame to a unique set of outstanding properties. They combine a high refractive index, hardness, great stability and inertness, and low electrical but high thermal conductivity. Diamond defects have recently attracted a lot of attention. Given this unique list of properties, it is not surprising that diamond nanoparticles are utilized for numerous applications. Due to their hardness, they are routinely used as abrasives. Their small and uniform size qualifies them as attractive carriers for drug delivery. The stable fluorescence of diamond defects allows their use as stable single photon sources or biolabels. The magnetic properties of the defects make them stable spin qubits in quantum information. This property also allows their use as a sensor for temperature, magnetic fields, electric fields, or strain. This Review focuses on applications in cells. Different diamond materials and the special requirements for the respective applications are discussed. Methods to chemically modify the surface of diamonds and the different hurdles one has to overcome when working with cells, such as entering the cells and biocompatibility, are described. Finally, the recent developments and applications in labeling, sensing, drug delivery, theranostics, antibiotics, and tissue engineering are critically discussed. PMID- 29573339 TI - Empowering education of arthroplasty patients' significant others in three Southern European countries. AB - AIMS AND OBJECTIVES: To examine the relationship between significant others' expected and received knowledge and their background characteristics in three Mediterranean countries (Cyprus, Greece, Spain), all of which deal with economic restrictions, have similar social support systems with the family members acting as family caregivers, and cultural similarities. BACKGROUND: Significant others' role is a key element in the older patients' postoperative recovery. However, people who take care of persons older than 65 years, as persons undergoing arthroplasty, are usually old themselves and need special support. DESIGN: Multicentre, descriptive, correlational study. METHODS: Data were collected preoperatively from 189 and postoperatively from 185 significant others using the Knowledge Expectations and the Received Knowledge of Significant Others Scales during 2010-2012. RESULTS: Approximately one-fourth of the significant others were older than 65 years. Their knowledge expectations were not adequately addressed in any of the countries; they expected to be educated more on biophysiological issues and received the lowest knowledge regarding financial issues. The highest difference between expected and received knowledge was found in Greece and the lowest in Cyprus. Significant others may be less prepared for dealing with situations at home due to the knowledge difference between expected and received knowledge. CONCLUSIONS: Significant others receive less education comparing to what they expect; therefore, they are not prepared for dealing with problematic situations during their old relative's recovery. This is especially important in Mediterranean countries, where family members often provide patient care. IMPLICATIONS FOR PRACTICE: As health care is changing towards active participation of patients and family, it is important that nurses provide the education needed, as lower education may lead to poor patient outcomes and higher education may lead to significant others' anxiety. Nurses may keep in mind that older significant others do not report higher knowledge difference, but may have lower expectations. PMID- 29573340 TI - The adsorption of dabigatran is as efficient as addition of idarucizumab to neutralize the drug in routine coagulation assays. AB - INTRODUCTION: The direct thrombin inhibitor dabigatran interferes with thrombophilia screening and with the diagnosis of hemostasis disorders that develop during treatment with the anticoagulant. In vitro addition of idarucizumab, a humanized antibody fragment that binds dabigatran, to plasma samples containing dabigatran fully neutralizes the drug. This study was carried out to determine whether binding of dabigatran on selected insoluble commercial adsorbent material, DOAC-STOPR , was as efficient as idarucizumab to neutralize the anticoagulant activity of the drug in vitro. METHODS: Coagulation assays sensitive to dabigatran were carried out with patient and control plasma samples spiked with dabigatran and supplemented with idarucizumab or incubated with adsorbent material. RESULTS: In samples containing upto 10 000 ng/mL dabigatran, the adsorption procedure was at least as efficient as the addition of idarucizumab to neutralize the activity of the anticoagulant drug. Neither the adsorption procedure nor the addition of idarucizumab did impair routine coagulation assays carried out with plasma devoid of dabigatran, such as the activated partial thromboplastin time, prothrombin time, fibrinogen Clauss, and the thrombophilia screening assays used to detect antiphospholipid antibodies or activated protein C resistance. In addition, the adsorption procedure did not interfere with the detection of lupus anticoagulant samples. CONCLUSIONS: Adsorption of dabigatran in plasma samples containing the drug neutralizes its activity as efficiently as the addition of idarucizumab. This method allows the evaluation of thrombophilia markers without interruption of anticoagulation therapy or the detection of hemostasis disorders in patients treated with the drug. PMID- 29573341 TI - A Modular System for the Design of Stimuli-Responsive Multifunctional Nanoparticle Aggregates by Use of Host-Guest Chemistry. AB - A self-assembly approach for the design of multifunctional nanomaterials consisting of different nanoparticles (gold, iron oxide, and lanthanide-doped LiYF4 ) is developed. This modular system takes advantage of the light-responsive supramolecular host-guest chemistry of beta-cyclodextrin and arylazopyrazole, which enables the dynamic and reversible self-assembly of particles to spherical nanoparticle aggregates in aqueous solution. Due to the magnetic iron oxide nanoparticles, the aggregates can be manipulated by an external magnetic field leading to the formation of linear structures. As a result of the integration of upconversion nanoparticles, the aggregates are additionally responsive to near infrared light and can be redispersed by use of the upconversion effect. By varying the nanoparticle and linker concentrations the composition, size, shape, and properties of the multifunctional nanoparticle aggregates can be fine-tuned. PMID- 29573342 TI - Prenatal diet and children's trajectories of hyperactivity-inattention and conduct problems from 3 to 8 years: the EDEN mother-child cohort. AB - BACKGROUND: Evidence shows that diet contributes substantially to lifelong physical and mental health. Although dietary exposure during gestation and early postnatal life is critical, human epidemiological data are limited regarding its link with children's subsequent externalizing issues. The aim of this study was to investigate the role of maternal diet during pregnancy in offspring's symptoms of hyperactivity-inattention and conduct problems from ages 3 to 8 years. METHODS: We used data of 1,242 mother-child pairs from a French cohort followed up from pregnancy until the children were 8 years of age. Dietary patterns (DP) of the mother during pregnancy were assessed with food frequency questionnaires. Children's externalizing behavior was assessed with the Strength and Difficulties Questionnaire at ages 3, 5, and 8 years, from which trajectories of hyperactivity inattention symptoms and conduct problems were derived. We conducted multivariable logistic models to study associations adjusted for a range of potential confounders. RESULTS: Results showed significant relationships between maternal 'low Healthy diet' (adjusted Odds Ratio (aOR) = 1.61; IC 95%: 1.09-2.37) and 'high Western diet' (aOR = 1.67; IC 95%: 1.13-2.47) during pregnancy and children's trajectories of high symptoms of hyperactivity-inattention. The associations took into account relevant confounders such as DP of the children at age 2 years, maternal stress and depression, gestational diabetes, and socioeconomic variables. CONCLUSIONS: Maternal diet during pregnancy was independently associated with children's hyperactivity-inattention symptoms but not with conduct problems. Early prevention addressing lifestyle should specifically target diet in pregnant women.

PMID- 29573343 TI - Reference intervals for plasma cystatin C and plasma creatinine in adults using methods traceable to international calibrators and reference methods. AB - INTRODUCTION: The aim of this study was to establish reference intervals for plasma cystatin C and creatinine in adults using the Gentians cystatin C method traceable to the international calibrator standard ERM-DA471/IFCC and a creatinine method traceable to the IDMS (Isotope Dilution Mass Spectrometry) creatinine reference method. METHODS: Blood samples were collected from 304 healthy blood donors (152 men and 152 women between 17 and 66 years old) with 30 31 men and 30-31 women in each ten-year interval. Plasma cystatin C was analyzed using the Gentian Cystatin C assay on a Roche cobas c702 analyzer, and plasma creatinine was analyzed using the CREA Plus assay on the Roche Modular P analyzer. RESULTS: The nonparametric reference intervals for plasma cystatin C were 0.58-1.00 mg/L in women (median 0.78 mg/L, range 0.56-1.06 mg/L) and 0.62 1.04 mg/L in men (median 0.79 mg/L, range 0.61-1.07 mg/L). The Mann-Whitney U test revealed no gender-related difference in plasma cystatin C (P = .21). A common reference interval in women and men was calculated to be 0.61-1.01 mg/L (median 0.79 mg/L, range 0.56-1.07 mg/L). The nonparametric reference interval for plasma creatinine was 52-89 MUmol/L in women (median 69 MUmol/L, range 52-92 MUmol/L) and 61-108 MUmol/L in men (median 86 MUmol/L, range 56-118 MUmol/L). The Mann-Whitney U test revealed a gender-related difference in plasma creatinine (P < .0001). CONCLUSION: In conclusion, we have established reference intervals for plasma cystatin C and creatinine in adults using methods traceable to international standards. PMID- 29573345 TI - Do clinical characteristics predict the cognitive course in early-onset schizophrenia-spectrum disorders? AB - BACKGROUND: Being in a period with extensive brain maturation, adolescents with early-onset schizophrenia-spectrum disorders (EOS) provide unique neurodevelopmental data that may contribute to a better understanding of schizophrenia at all ages. Cognitive dysfunction is a central feature of schizophrenia and is more pronounced in EOS than in later onset illness. However, there is limited research on both the long-term course of global cognition in EOS, and how cognition over time is influenced by clinical characteristics during the early illness period. METHODS: Thirty-one EOS patients and 73 controls (age 12-18) were assessed on clinical variables at baseline (PANSS, duration of untreated psychosis [DUP], hospitalizations, suicide attempts, and remission). Neuropsychological assessments with the MATRICS Consensus Cognitive Battery (MCCB) were conducted at baseline and after both 1 and 2 years, and composite scores of total performances were calculated. The analyses were performed with a linear mixed model. RESULTS: The present study found that global cognition followed a stable course over the first years of the disease in EOS, though at a significantly lower level in EOS compared with the controls. We did not detect a relationship between DUP, remission, positive/negative symptoms, and hospitalizations on one hand, and long-term cognition on the other hand, but PANSS-general and suicide attempt history at baseline were identified as risk factors of longitudinal cognitive function. CONCLUSIONS: Though at different levels, the EOS group and the controls had a similar cognitive course over 2 years. Some baseline characteristics (psychotic symptoms, DUP, remission, and hospitalization) had no influence on cognition within the first 2 years of illness. In contrast, general symptoms and a history of suicide attempts at baseline were more potent risk factors of the cognitive course than the psychotic specific symptoms, and should, therefore, be subject to specific attention in the evaluation and treatment of patients with early-onset psychosis. PMID- 29573346 TI - Isolated Fallopian Tube Torsion: A Unique Ultrasound Identity or a Serial Copycat? AB - OBJECTIVES: To report the preoperative ultrasound (US) signs of isolated fallopian tube torsion in surgically verified cases and to estimate whether preoperative US detection of this condition can be improved. METHODS: The charts of 27 women with a surgical diagnosis of isolated fallopian tube torsion at a tertiary medical center from 2005 to 2016 were retrospectively reviewed. Data were collected from the electronic database of the US unit and compared with the surgical findings. RESULTS: Isolated fallopian tube torsion was correctly diagnosed by US before surgery in 8 of the 27 women (29.6%). In the remainder, the US signs were attributed to torsion of the ovary or the entire adnexa (n = 13), or no torsion was suspected (n = 6). Fallopian tube edema was listed as a US finding in 7 patients, of whom 5 had a correct diagnosis of isolated fallopian tube torsion. The presence of a paraovarian cyst concomitant with normal appearing ovaries was assumed by US in 5 of the 8 cases that were accurately diagnosed as isolated fallopian tube torsion. The most misinterpreted US finding was an ovarian cyst (suspected in 10 patients and verified at surgery in 2). Absence of blood flow was described in 12 women, of whom 5 had an accurate diagnosis of isolated fallopian tube torsion. Six of the patients with a correct US diagnosis were adults (37.5% of total adults), and 2 were adolescents (18.2% of total adolescents). CONCLUSIONS: The US diagnosis of isolated fallopian tube torsion is challenging. A high index of suspicion is necessary to improve its detection, especially when there are possible US signs of torsion in the presence of a normal-appearing ovary. PMID- 29573347 TI - 5-Aza-7-deaza-2'-deoxyguanosine and 2'-Deoxycytidine Form Programmable Silver Mediated Base Pairs with Metal Ions in the Core of the DNA Double Helix. AB - 5-Aza-7-deaza-2'-deoxyguanosine (dZ) forms a silver-mediated base pair with dC. The metal ion pair represents a mimic of the H-bonded Watson-Crick dG-dC pair. The modified nucleoside displays a similar shape as the parent 2'-deoxyguanosine from which it can be constructed by transposition of nitrogen-7 to the bridgehead position-5. It lacks the major groove binding site as the positional change moves the dG- acceptor position from nitrogen-7 to nitrogen-1. As a shape mimic of dG, it fits nicely in the DNA double helix. The purine-pyrimidine dZ-dC hetero pair shows a relationship to the pyrimidine-pyrimidine dC-dC homo base pair. The dZ-dC pair forms a mismatch in the absence of silver ions and matches after addition of metal ions. Base-pair formation was verified on self-complementary 6-mer duplexes and 12-mer DNA with random composition by UV-dependent Tm measurements. Modified silver-mediated and hydrogen-bonded canonical base pairs can coexist. The dZ-Ag+ dC base pair is slightly less stable than the dG-dC pair, shows sequence dependence, and consumes one or two silver ions. These properties make the dZ-Ag+ -dC pair suitable for programmable incorporation of silver ions in DNA which cannot be achieved by canonical base pairs. If the silver ion content is higher than the total number of base pairs the duplexes turn into very stable structures in which all base pairs are considered to be in the silver-mediated pairing mode.

AB - To gain insight into the influence of metal-organic framework (MOF) fillers and polymers on membrane performance, eight different composites were studied by combining four MOFs and two polymers. MOF materials (NH2 -MIL-53(Al), MIL-69(Al), MIL-96(Al) and ZIF-94) with various chemical functionalities, topologies, and dimensionalities of porosity were employed as fillers, and two typical polymers with different permeability-selectivity properties (6FDA-DAM and Pebax) were selected as matrices. The best-performing MOF-polymer composites were prepared by loading 25 wt % of MIL-96(Al) as filler, which improved the permeability and selectivity of 6FDA-DAM to 32 and 10 %, while for Pebax they were enhanced to 25 and 18 %, respectively. The observed differences in membrane performance in the separation of CO2 from N2 are explained on the basis of gas solubility, diffusivity properties, and compatibility between the filler and polymer phases. PMID- 29573350 TI - A microscale HPLC-UV method for the determination of latamoxef in plasma: An adapted method for therapeutic drug monitoring in neonates. AB - Latamoxef, a broad-spectrum anti-bacterial agent of the beta-lactam antibiotics, is used off-label in treatment of neonatal sepsis. Large inter-individual variability and uncertainty of treatment make therapeutic drug monitoring (TDM) useful to optimize antimicrobial therapy. The objective of this study was to develop and validate a simple, selective and reliable HPLC method for the determination of latamoxef in small volumes of plasma, which could be used in neonatal TDM. After a simple protein precipitation, analytes were separated with liquid chromatography and quantified by UV detection, with tinidazole as the internal standard. The calibration range was linear from 3.0 to 60.0 MUg/mL. Intra- and inter-day precisions were < 7.2%. The acceptance criteria of accuracy (between 85 and 115%, 120% for lower limit of quantification) were met in all cases. A plasma volume of 50 MUL was required to achieve the limit of quantification of 3.0 MUg/mL. The TDM results showed a large variability in trough concentrations. A large number of patients were underdosed, highlighting the unmet need for TDM to optimize latamoxef therapy in neonates. PMID- 29573351 TI - Client and therapist match on gender, age, and income: Does match within the therapeutic dyad predict early growth in the therapeutic alliance? AB - OBJECTIVE: Because of the importance of the therapeutic alliance across psychotherapeutic treatments, it is important to study variables that predict the development of a positive therapeutic alliance. This study investigates if different levels of gender, age, and income match between therapists and clients predict early development of the therapeutic alliance. METHOD: The sample consisted of 28 therapists and 547 adult clients receiving individual psychotherapy for depressive symptoms. There were no exclusion criteria and no control over treatment delivery. Session-to-session assessments of the therapeutic alliance were collected and a growth mixture modeling framework with a priori identified classes corresponding to different levels of therapist-client match was utilized to examine differential alliance growth trajectories. RESULTS: No differential effect of match on any level was found on initial ratings of the alliance. Across levels of attribute match, clients tend to rate the alliance positively. Regarding growth, a "youth effect" and an "affluence effect" was noted. Dyads where the therapist is younger than the client, and dyads where the therapist is from a higher income status than the client, show additional growth in the alliance beyond positive initial ratings. This is effect is not constant across sessions. CONCLUSIONS: Matching on gender, income, and age can be used for case assignment heuristic, in particular to produce additional growth in the alliance beyond initial positive ratings. Clinical and scientific consequences of the study are discussed. PMID- 29573352 TI - Anti-high mobility group box-1 monoclonal antibody treatment of brain edema induced by influenza infection and lipopolysaccharide. AB - Encephalopathy is a major cause of influenza-associated child death and severe neurological sequelae in Japan, highlighting the urgent need for new therapeutic strategies. In this study, we evaluated the effects of anti-high mobility group box-1 monoclonal antibody (alpha-HMGB1) treatment on brain edema induced by influenza A virus (IAV) and lipopolysaccharide in 4-week-old BALB/c female mice. The results showed that administration of 7.5 mg/kg alpha-HMGB1 1 h after IAV (A/Puerto Rico/8/34) inoculation significantly alleviated brain edema at 48 h after IAV inoculation, as confirmed by the suppression of Evans Blue dye leakage and matrix metallopeptidase-9 mRNA expression in the brain. Moreover, we also observed suppression of oxidative stress and different cytokines in IAV inoculated mice. The expression of plasminogen activator inhibitor-1 was also attenuated following treatment with alpha-HMGB1. Notably, alpha-HMGB1 treatment had no effect on virus propagation in the lung. In summary, anti-HMGB1 treatment may improve the prognosis in cases with influenza-associated encephalopathy by attenuating brain edema and reducing the inflammatory responses induced by HMGB1. PMID- 29573353 TI - Influence of white matter injury on gray matter reactive gliosis upon stab wound in the adult murine cerebral cortex. AB - Traumatic brain injury frequently affects the cerebral cortex, yet little is known about the differential effects that occur if only the gray matter (GM) is damaged or if the injury also involves the white matter (WM). To tackle this important question and directly compare similarities and differences in reactive gliosis, we performed stab wound injury affecting GM and WM (GM+) and one restricted to the GM (GM-) in the adult murine cerebral cortex. First, we examined glial reactivity in the regions affected (WM and GM) and determined the influence of WM injury on reactive gliosis in the GM comparing the same area in the two injury paradigms. In the GM+ injury microglia proliferation is increased in the WM compared with GM, while proliferating astrocytes are more abundant in the GM than in the WM. Interestingly, WM lesion exerted a strong influence on the proliferation of the GM glial cells that was most pronounced at early stages, 3 days post lesion. While astrocyte proliferation was increased, NG2 glia proliferation was decreased in the GM+ compared with GM- lesion condition. Importantly, these differences were not observed when a lesion of the same size affected only the GM. Unbiased proteomic analyses further corroborate our findings in support of a profound difference in GM reactivity when WM is also injured and revealed MIF as a key regulator of NG2 glia proliferation.

PMID- 29573355 TI - Association of plasma neopterin with risk of an inpatient hospital diagnosis of atrial fibrillation: results from two prospective cohort studies. AB - BACKGROUND: Link between inflammation and atrial fibrillation (AF) has been increasingly recognized. Neopterin, a biomarker of cellular immune activation, may be associated with incident AF. OBJECTIVE: To investigate the association between plasma neopterin levels and risk of an inpatient hospital diagnosis of AF, and to evaluate a joint association of neopterin and a nonspecific inflammatory marker C-reactive protein (CRP) in two prospective cohorts. METHODS: We performed a prospective analysis from a community-based cohort (the Hordaland Health Study (HUSK), n = 6891), and validated the findings in a cohort of patients with suspected stable angina pectoris (the Western Norway Coronary Angiography Cohort (WECAC), n = 2022). RESULTS: In both cohorts, higher plasma levels of neopterin were associated with an increased risk of incident AF after adjustment for age, sex, body mass index, current smoking, diabetes, hypertension and renal function. The multivariable-adjusted hazard ratio (HR) (95% CI) per one SD increment of log-transformed neopterin was 1.20 (1.10-1.32) in HUSK and 1.26 (1.09-1.44) in WECAC. Additional adjustment for CRP did not materially affect the risk association for neopterin. The highest risk of AF was found among individuals with both neopterin and CRP levels above the median (HR: 1.54; 95% CI: 1.16-2.05 in HUSK and HR: 1.67; 95% CI: 1.11-2.52 in WECAC). CONCLUSIONS: Our findings indicate an association of plasma neopterin with risk of an inpatient hospital diagnosis of AF, which remains after adjustment for traditional risk factors as well as for CRP. This study highlights a role of cellular immune activation, in addition to inflammation, in AF pathogenesis.

AB - The G12 rotavirus genotype has emerged globally since their first detection in 1987 from the Philippines; however it remains a rare cause of gastroenteritis in Pakistan. Rotavirus surveillance conducted during 2015-2016, assessed 3446 children <5 years hospitalized for gastroenteritis and found 802 (23.2%) positive on ELISA. Genotyping of a subset of positive samples (n = 319) revealed G12P[6] (11.28%) as the third most common G/P combination following G3P[8] (28.5%) and G1P[8] (12.5%); G2P[4] (10.65%) and G3P[6] (8.15%) were other frequently detected strains. Phylogenetic analysis of G12 strains from Pakistan revealed high genetic similarity to G12 strains from Italy, Thailand, Korea, and Great Britain as well as local strains within G12 lineage III. In conclusion, G12P[6] was a major contributor of RVA gastroenteritis in Pakistani children. Robust surveillance after the introduction of rotavirus vaccines will help determine the evolution of G12 and other circulating genotypes in the country.

AB - PURPOSE: To optimize a selective inversion recovery (SIR) sequence for macromolecular content mapping in the human brain at 3.0T. THEORY AND METHODS: SIR is a quantitative method for measuring magnetization transfer (qMT) that uses a low-power, on-resonance inversion pulse. This results in a biexponential recovery of free water signal that can be sampled at various inversion/predelay times (tI/ tD ) to estimate a subset of qMT parameters, including the macromolecular-to-free pool-size-ratio (PSR), the R1 of free water (R1f ), and the rate of MT exchange (kmf ). The adoption of SIR has been limited by long acquisition times (~4 min/slice). Here, we use Cramer-Rao lower bound theory and data reduction strategies to select optimal tI /tD combinations to reduce imaging times. The schemes were experimentally validated in phantoms, and tested in healthy volunteers (N = 4) and a multiple sclerosis patient. RESULTS: Two optimal sampling schemes were determined: (i) a 5-point scheme (kmf estimated) and (ii) a 4-point scheme (kmf assumed). In phantoms, the 5/4-point schemes yielded parameter estimates with similar SNRs as our previous 16-point scheme, but with 4.1/6.1-fold shorter scan times. Pair-wise comparisons between schemes did not detect significant differences for any scheme/parameter. In humans, parameter values were consistent with published values, and similar levels of precision were obtained from all schemes. Furthermore, fixing kmf reduced the sensitivity of PSR to partial-volume averaging, yielding more consistent estimates throughout the brain. CONCLUSIONS: qMT parameters can be robustly estimated in <=1 min/slice (without independent measures of DeltaB0 , B1+, and T1 ) when optimized tI -tD combinations are selected.

AB - OBJECTIVE(S): To assess the prevalence of personal experiences of mental health problems among clinical psychologists, external, perceived, and self-stigma among them, and stigma-related concerns relating to disclosure and help-seeking. METHOD: Responses were collected from 678 UK-based clinical psychologists through an anonymous web survey consisting of the Social Distance Scale, Stig-9, Military Stigma Scale, Secrecy Scale, Attitudes towards Seeking Professional Psychological Help Scale-Short Form, alongside personal experience and socio-demographic questions. RESULTS: Two-thirds of participants had experienced mental health problems themselves. Perceived mental health stigma was higher than external and self-stigma. Participants were more likely to have disclosed in their social than work circles. Concerns about negative consequences for self and career, and shame prevented some from disclosing and help-seeking. CONCLUSIONS: Personal experiences of mental health problems among clinical psychologists may be fairly common. Stigma, concerns about negative consequences of disclosure and shame as barriers to disclosure and help-seeking merit further consideration.

AB - BACKGROUND: Since available arable land is limited and nitrogen fertilizers pollute the environment, cropping systems ought to be developed that do not rely on them. Here we investigate the rapidly growing, N2 -fixing Azolla/Nostoc symbiosis for its potential productivity and chemical composition to determine its potential as protein feed. RESULTS: In a small production system, cultures of Azolla pinnata and Azolla filiculoides were continuously harvested for over 100 days, yielding an average productivity of 90.0-97.2 kg dry weight (DW) ha-1 d-1 . Under ambient CO2 levels, N2 fixation by the fern's cyanobacterial symbionts accounted for all nitrogen in the biomass. Proteins made up 176-208 g kg-1 DW (4.9 * total nitrogen), depending on species and CO2 treatment, and contained more essential amino acids than protein from soybean. Elevated atmospheric CO2 concentrations (800 ppm) significantly boosted biomass production by 36-47%, without decreasing protein content. Choice of species and CO2 concentrations further affected the biomass content of lipids (79-100 g kg-1 DW) and (poly)phenols (21-69 g kg-1 DW). CONCLUSIONS: By continuous harvesting, high protein yields can be obtained from Azolla cultures, without the need for nitrogen fertilization. High levels of (poly)phenols likely contribute to limitations in the inclusion rate of Azolla in animal diets and need further investigation. (c) 2018 The Authors.

AB - Clinical Research Curcumin, a nontoxic bioactive agent of turmeric significantly reduces nicotine-induced toxicity both at cellular and genetic levels. The clinical implication of native curcumin is hindered in the target cells due to its low aqueous solubility, poor bioavailability and poor pharmacokinetics. The problem was tried to overcome by preparing nanocurcumin with a view to improve its aqueous solubility and better therapeutic efficacy against nicotine-induced toxicity. The prepared nanocurcumin was characterized by Ultraviolet-visible spectroscopy; Field emission scanning electron microscopy (FE-SEM); X-ray diffraction (XRD); and Fourier transform infrared spectroscopy (FTIR). Female albino rats of Wistar strain were daily exposed to effective dose of nicotine (2.5 mg/kg, injected subcutaneously) and supplemented with effective dose of curcumin (80 mg/kg body weight orally) or nanocurcumin (4 mg/kg body weight orally) for 21 days. The preventive efficacies of curcumin and nanocurcumin were evaluated against the changes in liver function enzymes, kidney function parameters, lipid profiles, lipid-peroxidation, anti-oxidant status, and tissues damages etc. Results revealed that nanocurcumin more effectively ameliorated the nicotine-induced toxicities at much lower concentration due to its higher aqueous solubility and more bioavailability. The nanocurcumin can be used as a potential therapeutic agent for better efficacy against nicotine-induced toxicities than native curcumin. PMID- 29573361 TI - RoMo: An efficient strategy for functional mosaic analysis via stochastic Cre recombination and gene targeting in the ROSA26 locus. AB - Functional mosaic analysis allows for the direct comparison of mutant cells with differentially marked control cells in the same organism. While this offers a powerful approach for elucidating the role of specific genes or signalling pathways in cell populations of interest, genetic strategies for generating functional mosaicism remain challenging. We describe a novel and streamlined approach for functional mosaic analysis, which combines stochastic Cre/lox recombination with gene targeting in the ROSA26 locus. With the RoMo strategy a cell population of interest is randomly split into a cyan fluorescent and red fluorescent subset, of which the latter overexpresses a chosen transgene. To integrate this approach into high-throughput gene targeting initiatives, we developed a procedure that utilizes Gateway cloning for the generation of new targeting vectors. RoMo can be used for gain-of-function experiments or for altering signaling pathways in a mosaic fashion. To demonstrate this, we developed RoMo-dnGs mice, in which Cre-recombined red fluorescent cells co express a dominant-negative Gs protein. RoMo-dnGs mice allowed us to inhibit G protein-coupled receptor activation in a fraction of cells, which could then be directly compared to differentially marked control cells in the same animal. We demonstrate how RoMo-dnGs mice can be used to obtain mosaicism in the brain and in peripheral organs for various cell types. RoMo offers an efficient new approach for functional mosaic analysis that extends the current toolbox and may reveal important new insights into in vivo gene function. PMID- 29573362 TI - Management of myringitis: Current concepts and review. AB - OBJECTIVES: This study reviews the proposed mechanisms underlying the development of myringitis and suggests optimal guidelines for the successful treatment and prevention of recurrence through a literature review. REVIEW METHODS: Studies reporting the treatment outcomes of myringitis were systematically reviewed by searching the MEDLINE, PubMed, and Embase databases for studies published from 2000 to 2017. The search for myringitis yielded 57 results, and 31 were found to be relevant. Thirteen articles related to bullous myringitis associated with acute otitis media were excluded; the remaining 18 were included in this study. The studies were reviewed with attention to clinical characteristics, treatment options, and results after treatment. RESULTS: Among 18 publications, 10 suggested therapeutic options for myringitis: 1) five studies suggested management using topical agents, 2) three studies suggested laser-assisted treatment, and 3) two studies suggested surgical treatment. Treatments using topical agents or a laser showed highly variable resolution rates (63.6%-100% and 20%-85.7%, respectively). Two studies introducing surgical therapy reported good treatment outcomes (95.8%-100%). Five articles discussed the characteristics or diagnosis of myringitis; however, there was a lack of evidence for the related mechanism. CONCLUSIONS: No well-designed randomized studies have assessed optimal treatments. Although surgery showed better treatment results than topical agents and laser-assisted treatment, the wide range of resolution rates indicates that proper patient selection is needed. Further studies are needed to improve the current understanding and management of myringitis. Laryngoscope, 128:2157-2162, 2018. PMID- 29573364 TI - Multiple gateways.

AB - In hyperarid deserts, endolithic microbial communities colonize the rocks' interior as a survival strategy. Yet, the composition of these communities and the drivers promoting their assembly are still poorly understood. We analysed the diversity and community composition of endoliths from four different lithic substrates - calcite, gypsum, ignimbrite and granite - collected in the hyperarid zone of the Atacama Desert, Chile. By combining microscopy, mineralogy, spectroscopy and high throughput sequencing, we found these communities to be highly specific to their lithic substrate, although they were all dominated by the same four main phyla, Cyanobacteria, Actinobacteria, Chloroflexi and Proteobacteria. Our finding indicates a fine scale diversification of the microbial reservoir driven by substrate properties. The data suggest that the overall rock chemistry and the light transmission properties of the substrates are not essential drivers of community structure and composition. Instead, we propose that the architecture of the rock, i.e., the space available for colonization and its physical structure, linked to water retention capabilities, is ultimately the driver of community diversity and composition at the dry limit of life. PMID- 29573366 TI - Inhibition in the face of emotion: Characterization of the spatial-temporal dynamics that facilitate automatic emotion regulation. AB - Emotion regulation mediates socio-cognitive functions and is essential for interactions with others. The capacity to automatically inhibit responses to emotional stimuli is an important aspect of emotion regulation; the underlying neural mechanisms of this ability have been rarely investigated. Forty adults completed a Go/No-go task during magnetoencephalographic (MEG) recordings, where they responded rapidly to either a blue or purple frame which contained angry or happy faces. Subjects responded to the target color in an inhibition (75% Go trials) and a vigilance condition (25% Go trials). As expected, inhibition processes showed early, sustained activation (200-450 ms) in the right inferior frontal gyrus (IFG). Emotion-related inhibition processes showed greater activity with angry faces bilaterally in the orbital-frontal gyri (OFG) starting at 225 ms and temporal poles from 250 ms, with right hemisphere dominance. The presence of happy faces elicited earlier activity in the right OFG. This study demonstrates that the timing of inhibition processes varies with the emotional context and that there is much greater activation in the presence of angry faces. It underscores the importance of the right IFG for inhibition processes, but the OFG in automatic emotion regulation. PMID- 29573367 TI - Proteome and acylome analyses of the functional interaction network between the carbazole-degradative plasmid pCAR1 and host Pseudomonas putida KT2440. AB - Understanding the interplay between a plasmid and its host system is a bottleneck towards prediction of the fate of plasmid-harbouring strains in the natural environments. Here, we studied the impact of the conjugative plasmid pCAR1, involved in carbazole degradation, on the proteome of Pseudomonas putida KT2440 using SILAC method. Furthermore, we investigated two acyl lysine modifications (acetylation and succinylation) that respond to the metabolic status of the cell and are implicated in regulation of various cellular processes. The total proteome analysis revealed that the abundance of key proteins involved in metabolism, signal transduction and motility was affected by pCAR1 carriage. In total, we identified 1359 unique acetylation sites on 637 proteins and 567 unique succinylation sites on 259 proteins. Changes in the acylation status of proteins involved in metabolism and translation by pCAR1 carriage were detected. Remarkably, acylation was identified on proteins involved in important plasmid functions, including partitioning and carbazole degradation, and on nucleoid associated proteins that play a key role in the functional interaction with the chromosome. This study provides a novel insight on the functional consequences of plasmid carriage and improves our understanding of the plasmid-host cross-talk. PMID- 29573368 TI - Supramolecular Organization in Confined Nanospaces. AB - Empty spaces are abhorred by nature, which immediately rushes in to fill the void. Humans have learnt pretty well how to make ordered empty nanocontainers, and to get useful products out of them. When such an order is imparted to molecules, new properties may appear, often yielding advanced applications. This review illustrates how the organized void space inherently present in various materials: zeolites, clathrates, mesoporous silica/organosilica, and metal organic frameworks (MOF), for example, can be exploited to create confined, organized, and self-assembled supramolecular structures of low dimensionality. Features of the confining matrices relevant to organization are presented with special focus on molecular-level aspects. Selected examples of confined supramolecular assemblies - from small molecules to quantum dots or luminescent species - are aimed to show the complexity and potential of this approach. Natural confinement (minerals) and hyperconfinement (high pressure) provide further opportunities to understand and master the atomistic-level interactions governing supramolecular organization under nanospace restrictions. PMID- 29573369 TI - Effect of hydraulic retention time on microbial community structure in wastewater treatment electro-bioreactors. AB - The impact of hydraulic retention time (HRT) on the performance and microbial community structure of control and electro-bioreactors was investigated. Control bioreactors and electro-bioreactors were operated at HRT ranging between 6 and 75 hr. The total bacterial counts in addition to the removal efficiency of NH4+ -N, sCOD, and PO43- -P was assessed in all the reactors tested. In addition, Illumina sequencing was performed to determine the microbial communities that developed in these reactors under each HRT condition. Phylogenetic analysis showed that Proteobacteria and Bacteroidetes were the dominant phyla in those reactors. In addition, Nitrospira sp. and Pseudomonas sp. were found to be present in electro bioreactors with higher relative abundance than in control bioreactors. The results presented here are the first to determine what different microbial communities in wastewater electro-bioreactors due to the application of an electric current under different HRTs. PMID- 29573370 TI - Nutrition-sensitive agricultural interventions and gender dynamics: A qualitative study in Nepal. AB - Undernutrition and low women's status persist as major development obstacles in South Asia and specifically, Nepal. Multi-sectoral approaches, including nutrition-sensitive agriculture, are potential avenues for further reductions in undernutrition. Although evidence is growing, many questions remain regarding how gender mediates the translation of agricultural production activities into nutritional benefit. In this study, we examined how gender influences the pathway from agricultural production to improved income and control of income, with a focus on five domains of empowerment: decision-making power, freedom of mobility, social support, workload and time, and self-efficacy. For this, we conducted a qualitative retrospective assessment (N = 10 FGDs) among 73 beneficiary women of a nutrition-sensitive agriculture programme implemented from 2008 to 2012 in two districts of Nepal-Baitadi and Kailali. We found that women reported increased decision-making power, new knowledge and skills, increased recognition by their family members of their new knowledge and contributions, and self-efficacy as farmers and sellers, whereas workload and time were the most consistent constraints noted. We also found that each empowerment domain operated differently at different stages of the pathway, sometimes representing barriers and at other times, opportunities and that the interconnectedness of the domains made them difficult to disentangle in practice. Finally, there were major contextual differences for some domains (e.g., freedom of mobility) between the two districts. Future policies and programmes need to include in-depth formative research to ensure that interventions address context-specific gender and social norms to maximise programmatic opportunities to achieve desired results. PMID- 29573371 TI - Effect of applied magnetic fields on motility and magnetotaxis in the uncultured magnetotactic multicellular prokaryote 'Candidatus Magnetoglobus multicellularis'. AB - Magnetotactic bacteria are found in the chemocline of aquatic environments worldwide. They produce nanoparticles of magnetic minerals arranged in chains in the cytoplasm, which enable these microorganisms to align to magnetic fields while swimming propelled by flagella. Magnetotactic bacteria are diverse phylogenetically and morphologically, including cocci, rods, vibria, spirilla and also multicellular forms, known as magnetotactic multicellular prokaryotes (MMPs). We used video-microscopy to study the motility of the uncultured MMP 'Candidatus Magnetoglobus multicellularis' under applied magnetic fields ranging from 0.9 to 32 Oersted (Oe). The bidimensional projections of the tridimensional trajectories where interpreted as plane projections of cylindrical helices and fitted as sinusoidal curves. The results showed that 'Ca. M. multicellularis' do not orient efficiently to low magnetic fields, reaching an efficiency of about 0.65 at 0.9-1.5 Oe, which are four to six times the local magnetic field. Good efficiency (0.95) is accomplished for magnetic fields >=10 Oe. For comparison, unicellular magnetotactic microorganisms reach such efficiency at the local magnetic field. Considering that the magnetic moment of 'Ca. M. multicellularis' is sufficient for efficient alignment at the Earth's magnetic field, we suggest that misalignments are due to flagella movements, which could be driven by photo , chemo- and/or other types of taxis. PMID- 29573372 TI - Mixotrophic metabolism by natural communities of unicellular cyanobacteria in the western tropical South Pacific Ocean. AB - Cyanobacteria are major contributors to ocean biogeochemical cycling. However, mixotrophic metabolism and the relative importance of inorganic and organic carbon assimilation within the most abundant cyanobacteria are still poorly understood. We explore the ability of Prochlorococcus and Synechococcus to assimilate organic molecules with variable C:N:P composition and its modulation by light availability and photosynthetic impairment. We used a combination of radiolabelled molecules incubations with flow cytometry cell sorting to separate picoplankton groups from the western tropical South Pacific Ocean. Prochlorococcus and Synechococcus assimilated glucose, leucine and ATP at all stations, but cell-specific assimilation rates of N and P containing molecules were significantly higher than glucose. Incubations in the dark or with an inhibitor of photosystem II resulted in reduced assimilation rates. Light enhanced cell-specific glucose uptake was generally higher for cyanobacteria (~50%) than for the low nucleic acid fraction of bacterioplankton (LNA, ~35%). Our results confirm previous findings, based mainly on cultures and genomic potentials, showing that Prochlorococcus and Synechococcus have a flexible mixotrophic metabolism, but demonstrate that natural populations remain primarily photoautotrophs. Our findings indicate that mixotrophy by marine cyanobacteria is more likely to be an adaptation to low inorganic nutrient availability rather than a facultative pathway for carbon acquisition. PMID- 29573374 TI - Silencing Arabidopsis CARBOXYL-TERMINAL DOMAIN PHOSPHATASE-LIKE 4 induces cytokinin-oversensitive de novo shoot organogenesis. AB - De novo shoot organogenesis (DNSO) is a post-embryonic development programme that has been widely exploited by plant biotechnology. DNSO is a hormonally regulated process in which auxin and cytokinin (CK) coordinate suites of genes encoding transcription factors, general transcription factors, and RNA metabolism machinery. Here we report that silencing Arabidopsis thaliana carboxyl-terminal domain (CTD) phosphatase-like 4 (CPL4RNAi ) resulted in increased phosphorylation levels of RNA polymerase II (pol II) CTD and altered lateral root development and DNSO efficiency of the host plants. Under standard growth conditions, CPL4RNAi lines produced no or few lateral roots. When induced by high concentrations of auxin, CPL4RNAi lines failed to produce focused auxin maxima at the meristem of lateral root primordia, and produced fasciated lateral roots. In contrast, root explants of CPL4RNAi lines were highly competent for DNSO. Efficient DNSO of CPL4RNAi lines was observed even under 10 times less the CK required for the wild type explants. Transcriptome analysis showed that CPL4RNAi , but not wild-type explants, expressed high levels of shoot meristem-related genes even during priming on medium with a high auxin/CK ratio, and during subsequent shoot induction with a lower auxin/CK ratio. Conversely, CPL4RNAi enhanced the inhibitory phenotype of the shoot redifferentiation defective2-1 mutation, which affected snRNA biogenesis and formation of the auxin gradient. These results indicated that CPL4 functions in multiple regulatory pathways that positively and negatively affect DNSO. PMID- 29573373 TI - The role of conserved charged residues in the bidirectional rotation of the bacterial flagellar motor. AB - Many bacteria rotate their flagella both counterclockwise (CCW) and clockwise (CW) to achieve swimming toward attractants or away from repellents. Highly conserved charged residues are important for that motility, which suggests that electrostatic interactions are crucial for the rotor-stator function. It remains unclear if those residues contribute equally to rotation in the CCW and CW directions. To address this uncertainty, in this study, we expressed chimeric rotors and stators from Vibrio alginolyticus and Escherichia coli in E. coli, and measured the rotational speed of each motor in both directions using a tethered cell assay. In wild-type cells, the rotational speeds in both directions were equal, as demonstrated previously. Some charge-neutralizing residue replacements in the stator decreased the rotational speed in both directions to the same extent. However, mutations in two charged residues in the rotor decreased the rotational speed only in the CCW direction. Subsequent analysis and previous results suggest that these amino acid residues are involved in supporting the conformation of the rotor, which is important for proper torque generation in the CCW direction. PMID- 29573375 TI - Anaesthetic efficacy of 4% articaine and 2% lidocaine for extraction and pulpotomy of mandibular primary molars: an equivalence parallel prospective randomized controlled trial. AB - AIM: To compare the anaesthetic efficacy for pain and behaviour during treatment with mandibular infiltration using 4% articaine (BI) with inferior dental nerve clock (IDNB) using 2% lidocaine for extraction or pulp therapy in mandibular primary molars. DESIGN: This was equivalence parallel prospective RCT. A total of 98 children aged 5-9 years old were randomly assigned into two groups: BI supplemented by buccal intrapapillary infiltration with 4% articaine; IDNB with 2% lidocaine supplemented with long buccal infiltration. Behaviour during the injection and treatment procedures was assessed using Wong-Baker Facial Rating Scale (W-BFRS), Visual Analogue Scale (VAS), and Frankl Behaviour Rating Scale (FBRS). RESULTS: During the injection phase, the absolute differences in success rates between the two techniques were 0.06 (95% CI: -0.11 to 0.23) for VAS and 0.08 (95% CI: -0.19 to 0.03) for the behaviour of the child (FBRS). FBRS results showed the equivalence of the two, whereas the VAS results showed nonequivalence with the 95% confidence intervals slightly exceeding the equivalence margin (+/ 0.20). W-BFRS success rates were 63.3% for both. During the treatment, VAS results showed similar success rates, demonstrating equivalence between the two as did the results for FBRS. CONCLUSION: The results suggested equivalence in success rates for both anaesthetic techniques during treatment. PMID- 29573376 TI - Chicken or egg? Outcomes of experimental manipulations of maternally transmitted hormones depend on administration method - a meta-analysis. AB - Steroid hormones are important mediators of prenatal maternal effects in animals. Despite a growing number of studies involving experimental manipulation of these hormones, little is known about the impact of methodological differences among experiments on the final results expressed as offspring traits. Using a meta analytical approach and a representative sample of experimental studies performed on birds, we tested the effect of two types of direct hormonal manipulations: manipulation of females (either by implantation of hormone pellets or injection of hormonal solutions) and manipulation of eggs by injection. In both types of manipulation we looked at the effects of two groups of hormones: corticosterone and androgens in the form of testosterone and androstenedione. We found that the average effect on offspring traits differed between the manipulation types, with a well-supported positive effect of egg manipulation and lack of a significant effect of maternal manipulation. The observed average positive effect for egg manipulation was driven mainly by androgen manipulations, while corticosterone manipulations exerted no overall effect, regardless of manipulation type. Detailed analyses revealed effects of varying size and direction depending on the specific offspring traits; e.g., egg manipulation positively affected physiology and behaviour (androgens), and negatively affected future reproduction (corticosterone). Effect size was negatively related to the dose of androgen injected into the eggs, but unrelated to timing of manipulation, offspring developmental stage at the time of measuring their traits, solvent type, the site of egg injection and maternal hormone delivery method. Despite the generally acknowledged importance of maternal hormones for offspring development in birds, the overall effect of their experimental elevation is rather weak, significantly heterogeneous and dependent on the hormone and type of manipulation. We conclude by providing general recommendations as to how hormonal manipulations should be performed in order to standardize their impact and the results achieved. We also emphasize the need for research on free-living birds with a focus on fitness related and other long-term effects of maternal hormones. PMID- 29573377 TI - The two major glucokinase isoforms show conserved functionality in beta-cells despite different subcellular distribution. AB - Glucokinase (GCK) is crucial to regulating glucose metabolism in the liver and in pancreatic beta-cells. There are two major GCK isoforms, hepatic and pancreatic GCKs, which differ only in exon 1. However, the functional differences between the two GCK isoforms remain poorly understood. Here, we used a beta-cell-targeted gene transfer vector to determine the impact of isoform-specific GCK overexpression on beta-cells in vitro and in vivo. We showed that pancreatic GCK had a nuclear localization signal unique to the pancreatic isoform, facilitating its nuclear distribution in beta-cells. Despite the difference in subcellular distribution, overexpression of GCK isoforms similarly enhanced glucose uptake and beta-cell proliferation in vitro. Overexpression of hepatic or pancreatic GCK also similarly enhanced beta-cell proliferation in normal diet mice without affecting fasting glucose and intraperitoneal glucose tolerance tests (IPGTT). Our further study on human GCK sequences identified disproportional GCK amino acid variants in exon 1, while mutations linked to maturity onset diabetes of the young type 2 (MODY2) were disproportionally found in exons 2 through 10. Our results therefore indicate functional conservation between the two major GCK isoforms despite their distinct subcellular distribution. PMID- 29573378 TI - Why do herpes simplex encephalitis and semantic dementia show a different pattern of semantic impairment in spite of their main common involvement within the anterior temporal lobes? AB - A very challenging problem in the domain of the cognitive neurosciences is to explain why herpes simplex encephalitis and semantic dementia show, respectively, a category-specific semantic disorder for biological entities and an across categories semantic disruption, despite highly overlapping areas of anterior temporal lobe damage. The aim of the present review consisted in trying to make a separate survey of anatomo-clinical investigations (single-case studies and group studies) and of activation studies, in order to analyse the factors that could explain these different patterns of semantic disruption. Factors taken into account in this review were laterality of lesions, disease aetiology, kind of brain pathology and locus of damage within the temporal lobes. Locus of damage within the temporal lobes and kind of brain pathology seemed to play the most important role, because in patients with herpes simplex encephalitis and category specific semantic disorder for biological entities the lesions prevailed in the anteromedial temporal lobes. Furthermore, the neuropathology concerned both the anterior temporal cortices and the white matter pathways connecting these areas with the posterior visual areas, whereas in semantic dementia the inferior longitudinal fasciculus involvement was restricted to the rostral temporal lobe and did not extend into the cortically uninvolved occipital lobe. PMID- 29573379 TI - Dopamine dysregulation hypothesis: the common basis for motivational anhedonia in major depressive disorder and schizophrenia? AB - Abnormalities in reward processing are crucial symptoms of major depressive disorder (MDD) and schizophrenia (SCH). Recent neuroscientific findings regarding MDD have led to conclusions about two different symptoms related to reward processing: motivational and consummatory anhedonia, corresponding, respectively, to impaired motivation to obtain rewards ('wanting'), and diminished satisfaction from consuming them ('liking'). One can ask: which of these is common for MDD and SCH. In our review of the latest neuroscientific studies, we show that MDD and SCH do not share consummatory anhedonia, as SCH patients usually have unaltered liking. Therefore, we investigated whether motivational anhedonia is the common symptom across MDD and SCH. With regard to the similarities and differences between the neural mechanisms of MDD and SCH, here we expand the current knowledge of motivation deficits and present the common underlying mechanism of motivational anhedonia - the dopamine dysregulation hypothesis - stating that any prolonged dysregulation in tonic dopamine signaling that exceeds the given equilibrium can lead to striatal dysfunction and motivational anhedonia. The implications for further research and treatment of MDD and SCH are also discussed. PMID- 29573380 TI - PFGE: a tool for examination of heterogeneity between the bacterial spot-causing xanthomonads of tomato plants in Bulgaria. AB - Pulsed-field gel electrophoresis (PFGE) is a highly discriminative molecular typing method that is used for epidemiological studies and investigation of outbreaks caused by different pathogens, including phytopathogenic Xanthomonas species. Bacterial spot (BS) is the most common and one of the most destructive diseases of tomato and pepper plants in Bulgaria. Several Xanthomonas species are known to cause BS, but the global distribution and genetic diversity of these species are not well understood. A collection of 100 BS-causing strains, isolated during the period of 1985-2012 from different tomato cultivars and weeds associated with tomato production areas from 11 geographic regions in Bulgaria, were screened for genetic diversity by genomic DNA restriction with rare-cutting endonucleases (XbaI and SpeI) subsequently resolved by PFGE. Two haplotypes for Xanthomonas vesicatoria and one haplotype for Xanthomonas gardneri strains were found. PMID- 29573381 TI - Effects of two lichen acids isolated from Pseudevernia furfuracea (L.) Zopf in cultured human lymphocytes. AB - The present study aims at assessing the efficacies of olivetoric acid (OA) and physodic acid (PA) isolated from Pseudevernia furfuracea (L.) Zopf (Parmeliaceae) in human lymphocytes (HLs) in vitro. 3-(4,5-Dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide and lactate dehydrogenase assays were performed to establish cytotoxicity in HLs. Besides, oxidative stress and genotoxicity were monitored by estimating the changes of total oxidative stress (TOS) and 8-hydroxy 2'-deoxyguanosine (8-OH-dG) levels, respectively, in HLs. At the same time, OA- and PA-induced total antioxidant capacity (TAC) levels in HLs were determined. Although especially low concentrations of OA (IC50=109.94 mg/L) and PA (IC50=665.49 mg/L) did not show cytotoxic effect at high levels in HLs, it was revealed that cytotoxicity was significantly (p<0.05) associated with oxidative stress and genotoxicity via correlation analysis. While TOS level in HLs did not statistically (p>0.05) increase in the presence of all treatments (0.5-100 mg/L) of PA, TAC level was increased by PA applications in certain concentrations (0.5 10 mg/L). Overall, the obtained data indicate that OA and especially PA as lichen compounds that do not cause oxidative stress can be a new resource of therapeutics as recognized in the present study with their high antioxidant features.

AB - BACKGROUND Around the world, disabilities due to musculoskeletal disorders have increased and are a major health problem worldwide. In recent years, stem cells have been considered to be powerful tools for musculoskeletal tissue engineering. Human adipose-derived stem cells (hADSCs) and amniotic fluid-derived stem cells (hAFSCs) undergo typical differentiation process into cells of mesodermal origin and can be used to treat muscular system diseases. The aim of the present study was to compare the biological characteristic of stem cells isolated from different human tissues (adipose tissue and amniotic fluid) with respect to myogenic capacity and skeletal and smooth muscle differentiation under the same conditions. MATERIAL AND METHODS hAFSCs and hADSCs were isolated during standard medical procedures and widely characterized by specific markers expression and differentiation potential. Both cell types were induced toward smooth and striated muscles differentiation, which was assessed with the use of molecular techniques. RESULTS For phenotypic characterization, both stem cell types were assessed for the expression of OCT-4, SOX2, CD34, CD44, CD45, and CD90. Muscle specific markers appeared in both stem cell types, but the proportion of positive cells showed differences depending on the experimental conditions used and the source from which the stem cells were isolated. CONCLUSIONS In this study, we demonstrated that hADSCs and hAFSCs have different capability of differentiation toward both muscle types. However, hADSCs seem to be a better source for myogenic protocols and can promote skeletal and smooth muscle regeneration through either direct muscle differentiation or by paracrine mechanism.

AB - We conducted an on-line survey among 255 specialists in Hygiene and Preventive Medicine in Italy who completed their training between October 2014 and July 2016, to assess their training experience, employment opportunities and current job satisfaction. Response rate was 49%. Mean age was 35 years. A high employment rate within two years from obtaining specialist qualification was reported by the 125 specialists who completed the questionnaire (76% are currently employed). The three main work settings of the participating specialists are hospital health directions (37%), universities (19%) and local Prevention Departments (16%). Two thirds (66%) have temporary positions and only 6% permanent positions. Job, pay, and training satisfaction are often below expectations with geographical differences that would need to be further investigated.

AB - The Authors present the results of a study performed during a time-period of two years, to evaluate the hygienic quality of ready-to-eat foods, prepared and served in a hospital catering service, and the microbiological status of food contact surfaces. Food hygiene was evaluated using non-pathogenic indicator microorganisms. The study was part of the verification activities that the hospital Health Department considers as a priority in order to guarantee patient safety. Only one of 52 food samples tested was considered unsatisfactory; the examined surfaces were not fully satisfactory in one of four cases. The study results, although encouraging as a whole, especially with respect to the hygienic safety of food prepared and served in the hospital, confirm the need to continuously verify that the appropriate environmental sanitation procedures are applied, even in the case of outsourcing. Considering the increased susceptibility of hospitalized patients, this remains a priority in the hospital where the study was performed. PMID- 29573386 TI - [Lying in dementia care]. AB - The indiscriminate use of lying, when communicating with patients with dementia, is questioned in terms of ethics and acceptability. In this article we present the concept of "therapeutic lying", to describe those situations where a "non truth" is used in the patient's interest and not that of the healthcare professional. The debate is still open, so it is necessary to better clarify risks and benefits of lying in the context of care, both to safeguard patients and to allow healthcare professionals to respect ethical and moral standards.

AB - Obstructive Sleep Apnea Syndrome (OSAS) is a sleeping disorder caused by repeated episodes of partial or complete obstruction of the upper airways during sleep. During 2013, a pilot project was performed in the Marche region (Italy), co jointly by the University "Politecnica delle Marche" and the Italian National Institute of Work Accident Insurance (INAIL), among holders of a category "B" driver's licence and among professionals undergoing screening at an Occupational Medicine Service covering the Province of Pesaro-Urbino (Italy). Nineteen percent of 553 subjects undergoing a screening examination were found to be affected by OSAS. The data collected is of great interest in the phase of implementation of new national laws.

AB - AIM: The main objective of the study was to measure caregiver burden among informal caregivers assisting people with multiple sclerosis (MS). BACKGROUND: Thirty percent of people with multiple sclerosis require some form of home assistance and 80% of such care is provided by informal caregivers. The quality of life of informal caregivers of patients with multiple sclerosis decreases with increasing physical and depressive symptoms of their loved ones. This can have effects on stress levels, physical and mental health, quality of life, and mortality of informal caregivers. DESIGN: A descriptive correlational study was performed in a sample of informal caregivers of MS patients. METHODS: The study enrolled 41 informal caregivers of MS patients at a regional reference center in Rome, Italy. Data collection took place in the period between May and September 2016. A paper questionnaire was used, comprising a socio-demographic section and a "Caregiver Burden Inventory" section. RESULTS: The subjective burden perceived by informal caregivers of patients with MS is moderate. Socio-demographic characteristics were not found to influence burden of caregivers. CONCLUSIONS: It is important for nursing professionals to consider and evaluate the burden of informal caregivers of MS patients as they are valuable allies in the management of these patients. PMID- 29573389 TI - [Incidence of biological accidents at work and immune status for vaccine preventable diseases among resident physicians in specialist training at Ferrara University Hospital]. AB - The hospital as a work environment is particularly characterized by various risks for healthcare workers (HCWs). The main risk is represented by biological accidents, associated with the parenteral transmission of pathogens. Biological injuries can occur during the care service and the manipulation of biological fluids. Hepatitis B (and hepatitis D), hepatitis C and HIV are the most common infections transmitted by biological injuries. Physicians should acquire awareness of the risks associated with their professional activity during their training as medical residents (MRs). Some infectious diseases are preventable by vaccination and the "National Immunization Plan 2017-2019" (PNPV) recommends HCWs vaccination against hepatitis B, influenza, measles -mumps -rubella, chicken pox, and pertussis. Besides, not only HCWs' vaccination can prevent the disease in healthcare professionals, but it also may reduce the transmission to patients. Therefore, active immunization of HCWs by recommended vaccinations plays an important role to prevent disease cases, complications and death in patients. An increased awareness of risk behaviors is the first important point to address in order to reduce biological accidents and infectious diseases transmission, so as to reduce their frequency. Besides, HCWs' vaccination is useful to reinforce protection and to prevent the transmission of some infectious diseases in case of exposure. The aim of this five-year incidence study is to investigate the MRs' biological accidents characteristics and to analyze the MRs' immune status at the University of Ferrara in the period 2011-2015. Data on MRs' biological accidents and immune status at Azienda Ospedaliero-Universitaria of Ferrara in 2011-2015 were analyzed by Microsoft Excel 2007 Software. In this study, the percentage of MRs' biological injuries compared to the total number of MRs showed an annual variability, with a peak in 2011 (11.9%). During the analyzed period, there were 190 biological injuries among the MRs: 81% were percutaneous injuries and blood was the biological fluid involved in 86.3% of cases. The most frequent lesion was puncture (62.6%), occurred in 41.1% of cases by suture needles; 46.3% of accidents occurred in the operating block. These data can be explained by the more invasive and at risk activities carried out in these Operative Units. The high injuries percentage in MRs may be related to less work experience and inadequate training or informations about personal protective equipment use. Among MRs, 93.7%, 93.3% and 96.6% were immune to measles, chicken pox and hepatitis B, respectively; only in the case of rubella, 11.9% of MRs was not immune. This research showed, accordingly to published data, high adhesion to hepatitis B vaccination. However, the healthcare workers' vaccine coverage is still sub-optimal; active immunization by recommended vaccines should be implemented for both parenteral and airborne diseases. As a matter of fact, the recent measles outbreak has involved healthcare workers (4689 cases of measles, 305 in HCWs). Finally, the General Directorates of Health-care settings should improve healthcare personnel adhesion to vaccinations, such as influenza, by promotion activities in the workplace. A proposal in order to achieve coverage objectives could be making vaccinations mandatory, as well as already implemented in other countries.

PMID- 29573391 TI - Interventional management of hyperhidrosis in secondary care: a systematic review. AB - BACKGROUND: Hyperhidrosis is uncontrollable excessive sweating, which occurs at rest, regardless of temperature. The symptoms of hyperhidrosis can significantly affect quality of life. OBJECTIVES: To undertake a systematic review of the clinical effectiveness and safety of treatments available in secondary care for the management of primary hyperhidrosis. METHODS: Fifteen databases (including trial registers) were searched to July 2016 to identify studies of secondary-care treatments for primary hyperhidrosis. For each intervention randomized controlled trials (RCTs) were included where available; where RCT evidence was lacking, nonrandomized trials or large prospective case series were included. Outcomes of interest included disease severity, sweat rate, quality of life, patient satisfaction and adverse events. Trial quality was assessed using a modified version of the Cochrane Risk of Bias tool. Results were pooled in pairwise meta analyses where appropriate, otherwise a narrative synthesis was presented. RESULTS: Fifty studies were included in the review: 32 RCTs, 17 nonrandomized trials and one case series. The studies varied in terms of population, intervention and methods of outcome assessment. Most studies were small, at high risk of bias and poorly reported. The interventions assessed were iontophoresis, botulinum toxin (BTX) injections, anticholinergic medications, curettage and newer energy-based technologies that damage the sweat gland. CONCLUSIONS: The evidence for the effectiveness and safety of treatments for primary hyperhidrosis is limited overall, and few firm conclusions can be drawn. However, there is moderate-quality evidence to support the use of BTX for axillary hyperhidrosis. A trial comparing BTX with iontophoresis for palmar hyperhidrosis is warranted.

PMID- 29573392 TI - Patterns of dopamine transporter imaging in subtypes of multiple system atrophy. AB - OBJECTIVES: To investigate the differences in the pattern of striatal (caudate and putamen) dopamine transporter (DAT) loss in a multiple system atrophy (MSA) cohort, based on the clinical variants parkinsonian subtype (MSA-P) and cerebellar subtype (MSA-C) via (11)C-N-2-carbomethoxy-3-(4-fluorophenyl)-tropane (11 C-CFT) positron emission tomography (PET) imaging. MATERIALS AND METHODS: One hundred and six subjects (forty-one patients with probable MSA-P; forty patients with probable MSA-C; twenty-five healthy controls) underwent 11 C-CFT PET. Subregional 11 C-CFT uptake of bilateral caudate, anterior putamen, and posterior putamen was calculated respectively to measure the striatal dopaminergic function. RESULTS: Significant decrease in DAT binding in striatum was revealed in patients with MSA-C and MSA-P compared to normal controls (all regions, MSA-C vs controls, P < .0001; MSA-P vs controls, P < .0001). DAT reduction was more pronounced in MSA-P patients than that in MSA-C patients (all regions, P < .0001). Eleven of forty MSA-C patients displayed no DAT loss, whereas striatal DAT loss was evident in all MSA-P patients. MSA-P subtype showed a more obvious anteroposterior gradient of DAT loss and more asymmetric dopaminergic dysfunction compared to MSA-C patients. CONCLUSION: The subtypes of MSA studied here show significantly different spatial/anatomic patterns of striatonigral degeneration which may provide insights into their disease pathophysiology. Specifically, MSA P patients exhibit an uneven and much greater pronounced loss of dopamine innervation, while a relatively uniform pattern is revealed in patients with the MSA-C. Furthermore, the typical reduction in DAT 11 C-CFT binding in striatum is not present in all MSA-C patients, with a minority of cases showing normal DAT binding.

PMID- 29573396 TI - Trait differences in responses to arbuscular mycorrhizal fungi are stronger and more consistent than fixed differences among populations of Asclepias speciosa. AB - PREMISE OF THE STUDY: Arbuscular mycorrhizal (AM) fungi can promote plant growth and reproduction, but other plant physiological traits or traits that provide defense against herbivores can also be affected by AM fungi. However, whether responses of different traits to AM fungi are correlated and whether these relationships vary among plants from different populations are unresolved. METHODS: In a common garden experiment, we grew Asclepias speciosa plants from seed collected from populations found along an environmental gradient with and without AM fungi to assess whether the responses of six growth and defense traits to AM fungi are correlated. KEY RESULTS: Although there was strong genetic differentiation in mean trait values among populations, AM fungi consistently increased expression of most growth and defense traits across all populations. Responses of biomass and root to shoot ratio to AM fungi were positively correlated, suggesting that plants that are more responsive to AM fungi allocated more biomass belowground. Responses of biomass and trichome density to AM fungi were negatively correlated, indicating a trade-off in responsiveness between a growth and defensive trait. CONCLUSIONS: Our results suggest that while there is substantial population differentiation in many traits of A. speciosa, populations respond similarly to AM fungi, and both positive and negative correlations among trait responses occur.

PMID- 29573399 TI - Cerebrovascular autoregulation monitoring and patient-centred outcomes after cardiac surgery: a systematic review. AB - BACKGROUND: Impaired cerebrovascular autoregulation (CVAR) is observed in up to 20% of cardiac surgical patients. This systematic review aims to evaluate the association between impaired CVAR, measured by current monitoring techniques, and patient-centred outcomes in adults following cardiac surgery. METHODS: MEDLINE, EMBASE, PubMed, MEDLINE In-Process and Cochrane Library were systematically searched through 8 December 2017. Studies were included if they assessed associations between CVAR and patient-centred outcomes in the adult cardiac surgical population. The primary outcome of this systematic review was mortality. Secondary outcomes were stroke, delirium and acute kidney injury. Risk of bias was systematically assessed, and the GRADE methodology was used to evaluate the quality of evidence across outcomes. RESULTS: Eleven observational studies and no randomised controlled trials met the inclusion criteria. Due to methodological heterogeneity, meta-analysis was not possible. There was a high risk of bias within individual studies and low quality of evidence across outcomes. Of the included studies, one assessed mortality, five assessed stroke, four assessed delirium, and three assessed acute kidney injury. No reliable conclusions can be drawn from the one study assessing mortality. Interpretation of studies investigating CVAR and stroke, delirium and acute kidney injury was complicated by the lack of standardisation of monitoring techniques as well as varying definitions of impaired CVAR. CONCLUSIONS: There is a paucity of high quality evidence for CVAR monitoring and its associations with outcome measures in post cardiac surgical patients, highlighting the need for future studies. PMID- 29573398 TI - Integrated and Person-Centered Care for Community-Living Older Adults: A Cost Effectiveness Study. AB - OBJECTIVES: To assess the cost-effectiveness of Embrace, an integrated primary care service for older adults. DATA SOURCES: Care and support claims from health care insurers, long-term care administration, and municipalities for enrolled older adults between 2011 and 2013. STUDY DESIGN: A total of 1,456 older adults, listed with 15 general practitioners practices in the Netherlands, were stratified into risk profiles ("Robust," "Frail," and "Complex care needs") and randomized to Embrace or care-as-usual groups. Incremental costs were calculated per quality-adjusted life year, per day able to age in place, and per percentage point risk profile improvement. PRINCIPAL FINDINGS: Total average costs were higher for Embrace compared to care-as-usual. Differences in health-associated outcomes were small and not statistically significant. Probabilities that Embrace is cost-effective were below 80 percent, except for "risk profile improvements" within risk profile "Complex care needs." Complete case analysis resulted in smaller differences in total average costs across conditions and differences in health-associated outcomes remained small. CONCLUSIONS: According to current standards, Embrace is not considered cost effective after 12 months. However, it could be considered worthwhile in terms of "risk profile improvements" for older adults with "Complex care needs," if society is willing to invest substantially. PMID- 29573400 TI - Retrospective study of perampanel efficacy and tolerability in myoclonic seizures. AB - OBJECTIVES: Perampanel is an antiepileptic drug (AED) approved for add-on treatment of focal seizures (with or without generalization) and primary generalized tonic-clonic (GTC) seizures. Our objective was to explore the effectiveness and tolerability of adjunctive perampanel in patients with drug resistant myoclonic seizures, after failure of other AEDs. MATERIALS AND METHODS: Retrospective, multicenter, observational study. Data were collected from individual patient clinical files and analysed using appropriate descriptive statistics and inferential analyses. RESULTS: Data are reported for 31 patients with mean age 36.4 years, who had an average epilepsy duration of 18 years, previously taken an average of 5.03 AEDs, and were taking an average of 2.4 AEDs on perampanel initiation. Patients exhibited myoclonic, GTC, absence, tonic and focal seizures, and most had associated cognitive decline and/or ataxia. Median time on perampanel was 6 months, most common dose was 6 mg, and overall retention rate was 84%. The responder rate for myoclonic seizures was defined via reduction of days with myoclonic seizures per month. At 6 months, 15 (48.4%) of the 31 patients were classed as myoclonic seizure responders, 10 (32.3%) were myoclonic seizure free, and 39% saw improvements in functional ability. Of 17 patients with GTC seizures at baseline, 9 (53%) were responders at 6 months, and 8 (47.1%) were seizure free. The most frequent side effects were psychiatric disorders, instability, dizziness and irritability, and mostly resolved with dose reduction. Five patients discontinued perampanel due to side effects. CONCLUSIONS: Perampanel caused clinically meaningful improvements in patients with drug resistant myoclonic seizures. It was generally well tolerated, but psychiatric and neurological side effects sometimes required follow-up and dose reduction.

PMID- 29573402 TI - Minor neurological dysfunction and associations with motor function, general cognitive abilities, and behaviour in children born extremely preterm. AB - AIM: To study the prevalence of minor neurological dysfunction (MND) at 6 years of age in a cohort of children born extremely preterm without cerebral palsy (CP) and to investigate associations with motor function, cognitive abilities, and behaviour. METHOD: This study assessed 80 children born at less than 27 weeks of gestation and 90 children born at term age between 2004 and 2007 at a mean age of 6 years 6 months. The assessments included a simplified version of the Touwen Infant Neurological Examination, the Movement Assessment Battery for Children, Second Edition (MABC-2), Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV), the Strengths and Difficulties Questionnaire (SDQ), and the parent version of the Five to Fifteen questionnaire. RESULTS: Fifty-one of the children born preterm had normal neurology, 23 had simple MND, and six had complex MND compared with 88 who had normal neurology and two simple MND in the term-born group (p<0.001). There were significant differences between the children with normal neurology and MND in the preterm group in MABC-2-assessed motor function (p<0.001), general cognitive abilities with WISC-IV (p=0.005), and SDQ overall behavioural problems and peer problems reported by the parents (p=0.021 and p=0.003 respectively). SDQ teacher-reported overall behavioural and hyperactivity problems were significantly different between children with normal and simple MND (p=0.036 and p=0.019). INTERPRETATION: Children born extremely preterm, in the absence of CP, are at risk of MND and this is associated with motor function, cognitive ability, and behaviour. WHAT THIS PAPER ADDS: Extremely preterm birth carries a risk of minor neurological dysfunction (MND). MND in children born extremely preterm is associated with impaired motor function and cognitive abilities, and behavioural problems. Male sex is associated with MND in children born extremely preterm. PMID- 29573403 TI - The clinical outcome and neuroimaging of acute encephalopathy after status epilepticus in Dravet syndrome. AB - AIM: To analyze the clinical outcome and neuroimaging over a long duration follow up in the currently largest series of acute encephalopathy after status epilepticus in patients with Dravet syndrome. METHOD: Clinical and neuroimaging data of patients with Dravet syndrome with a history of acute encephalopathy (coma >24h) after status epilepticus from February 2005 to December 2016 at Peking University First Hospital were reviewed retrospectively. RESULTS: Thirty five patients (15 males, 20 females) with a history of acute encephalopathy were enrolled from a total of 624 patients with Dravet syndrome (5.6%). The median onset age of acute encephalopathy was 3 years 1 month. The duration of status epilepticus varied between 40 minutes to 12 hours. Thirty-four patients had a high fever when status epilepticus occurred, and only one had a normal temperature. Coma lasted from 2 to 20 days. Twelve patients died and 23 survived with massive neurological regression. The median follow-up time was 2 years 1 month. Neuroimaging of 20 out of 23 survivors during the recovery phase showed diverse degrees of cortical atrophy with or without subcortical lesions. INTERPRETATION: Acute encephalopathy after status epilepticus is more prone to occur in patients with Dravet syndrome who had a high fever. The mortality rate is high in severe cases. Survivors are left with severe neurological sequelae but often with either no seizure or low seizure frequency. WHAT THIS PAPER ADDS: Acute encephalopathy is more prone to occur in patients with Dravet syndrome with a high fever. The mortality rate is high for acute encephalopathy after status epilepticus in patients with Dravet syndrome. Survivors have neurological sequelae. PMID- 29573405 TI - Inferring the evolutionary reduction of corm lobation in Isoetes using Bayesian model-averaged ancestral state reconstruction. AB - PREMISE OF THE STUDY: Inferring the evolution of characters in Isoetes has been problematic, as these plants are morphologically conservative and yet highly variable and homoplasious within that conserved base morphology. However, molecular phylogenies have given us a valuable tool for testing hypotheses of character evolution within the genus, such as the hypothesis of ongoing morphological reductions. METHODS: We examined the reduction in lobe number on the underground trunk, or corm, by combining the most recent molecular phylogeny with morphological descriptions gathered from the literature and observations of living specimens. Ancestral character states were inferred using nonstationary evolutionary models, reversible-jump MCMC, and Bayesian model averaging. KEY RESULTS: Our results support the hypothesis of a directional reduction in lobe number in Isoetes, with the best-supported model of character evolution being one of irreversible reduction. Furthermore, the most probable ancestral corm lobe number of extant Isoetes is three, and a reduction to two lobes has occurred at least six times. CONCLUSIONS: From our results, we can infer that corm lobation, like many other traits in Isoetes, shows a degree of homoplasy, and yet also shows ongoing evolutionary reduction. PMID- 29573404 TI - Correlation of natural autoantibodies and cardiovascular disease-related anti bacterial antibodies in pericardial fluid of cardiac surgery patients. AB - Our previous studies showed that anti-citrate synthase (anti-CS) immunoglobulin (Ig)M natural autoantibodies are present in healthy individuals without previous antigen stimulation, but no studies have investigated their presence in the pericardial fluid (PF). Therefore, we detected the natural anti-CS IgG/M autoantibody levels in plasma and PF of cardiac surgery patients and investigated their relationship with cardiovascular disease-associated bacterial pathogens. PF and blood samples of 22 coronary artery bypass graft (CABG) and 10 aortic valve replacement (AVR) patients were tested for total Ig levels, natural autoantibodies and infection-related antibodies using enzyme-linked immunosorbent assay (ELISA) and Luminex methods. The B cell subsets were measured by flow cytometry. The total Ig subclass levels were four to eight times lower in PF than in plasma, but the natural anti-CS IgM autoantibodies showed a relative increase in PF. The frequency of CD19+ B lymphocytes was significantly lower in PF than in blood (P = 0.01), with a significant relative increase of B1 cells (P = 0.005). Mycoplasma pneumoniae antibody-positive patients had significantly higher anti-CS IgM levels. In CABG patients we found a correlation between anti-CS IgG levels and M. pneumoniae, Chlamydia pneumoniae and Borrelia burgdorferi antibody titres. Our results provide the first evidence that natural autoantibodies are present in the PF, and they show a significant correlation with certain anti-bacterial antibody titres in a disease-specific manner. PMID- 29573406 TI - T helper 17 cell/regulatory T-cell imbalance in hidradenitis suppurativa/acne inversa: the link to hair follicle dissection, obesity, smoking and autoimmune comorbidities. AB - BACKGROUND: Disintegration of the infundibula of terminal hair follicles (HFs) in intertriginous skin areas exhibits the histological hallmark of hidradenitis suppurativa (HS)/acne inversa, featuring a dissecting terminal hair folliculitis. Elevated serum levels of interleukin (IL)-17 and local increase in the ratio of proinflammatory T helper (Th)17 cells and anti-inflammatory regulatory T cells (Tregs) have been reported. Perifollicular Tregs play a key role in HF stem cell homeostasis and infundibular integrity. OBJECTIVES: In this review, we evaluate the Th17/Treg ratio in HS, its aggravating conditions and associated comorbidities. Furthermore, we intended to clarify whether drugs with reported beneficial effects in the treatment of HS readjust the deviated Th17/Treg axis. METHODS: PubMed-listed, peer-reviewed original research articles characterizing Th17/Treg regulation in HS/acne inversa and associated comorbidities were selected for this review. RESULTS: This review presents HS as a disease that exhibits an increased Th17/Treg ratio. Perifollicular deficiencies in Treg numbers or function may disturb HF stem cell homeostasis, initiating infundibular dissection of terminal HFs and perifollicular inflammation. The Th17/Treg imbalance is aggravated by obesity, smoking and decreased Notch signalling. In addition, HS-associated autoimmune diseases exhibit a disturbed Th17/Treg axis resulting in a Th17-dominant state. All drugs that have beneficial effects in the treatment of HS normalize the Th17/Treg ratio. CONCLUSIONS: HS immunopathogenesis is closely related to deviations of the Th17/Treg balance, which may negatively affect Treg-controlled HF stem cell homeostasis and infundibular integrity. Pharmacological intervention should not only attenuate Th17/IL-17 signalling, but should also improve Treg function in order to stabilize HF stem cell homeostasis and infundibular integrity. PMID- 29573407 TI - Impaired muscle growth precedes development of increased stiffness of the triceps surae musculotendinous unit in children with cerebral palsy. AB - AIM: If increased muscle stiffness and contractures in children with cerebral palsy (CP) are related to impaired muscle growth, reduced muscle growth should precede or coincide with increased muscle stiffness during development. Here, we compared the volume of the medial gastrocnemius muscle and the passive (non neural) stiffness of the triceps surae musculotendinous unit in typically developing children and children with CP from birth until 4 years of age. METHOD: Forty-one children with CP and 45 typically developing children were included. Freehand three-dimensional ultrasound was used to evaluate the volume of the medial gastrocnemius muscle. Biomechanical and electrophysiological measures were used to determine passive and reflex mediated stiffness of the triceps surae musculotendinous unit. RESULTS: Medial gastrocnemius muscle volume increased with the same rate in typically developing and children with CP until 12 months of age, when a significant smaller rate of growth was observed in children with CP. Passive stiffness of the triceps surae musculotendinous unit showed a linear increase with age in typically developing children. Children with CP older than 27 months showed a significant increase in passive stiffness. Reflex mediated stiffness was only pathologically increased in four children with CP. INTERPRETATION: The deviation of medial gastrocnemius muscle volume, earlier than musculotendinous unit stiffness, is consistent with the hypothesis. The data also point out that muscle atrophy and muscle stiffness already develops within the first 1 to 2 years. This emphasizes the necessity of early interventions to promote lower limb muscle growth in this population. WHAT THIS PAPER ADDS: Medial gastrocnemius muscle growth is reduced in children with cerebral palsy (CP) around 12 months after birth. Triceps surae musculotendinous unit stiffness is increased in children with CP around 27 months after birth. Reflex excitability is rarely increased in children with CP. Reduced muscle growth may be involved in the pathophysiology of contractures. PMID- 29573408 TI - Classic infantile Pompe patients approaching adulthood: a cohort study on consequences for the brain. AB - AIM: To examine the long-term consequences of glycogen storage in the central nervous system (CNS) for classic infantile Pompe disease using enzyme replacement therapy. METHOD: Using neuropsychological tests and brain magnetic resonance imaging (MRI), we prospectively assessed a cohort of 11 classic infantile Pompe patients aged up to 17 years. RESULTS: From approximately age 2 years onwards, brain MRI showed involvement of the periventricular white matter and centrum semiovale. After 8 years of age, additional white-matter abnormalities occurred in the corpus callosum, internal and external capsule, and subcortical areas. From 11 years of age, white-matter abnormalities were also found in the brainstem. Although there seemed to be a characteristic pattern of involvement over time, there were considerable variations between patients, reflected by variations in neuropsychological development. Cognitive development ranged from stable and normal to declines that lead to intellectual disabilities. INTERPRETATION: As treatment enables patients with classic infantile Pompe disease to reach adulthood, white-matter abnormalities are becoming increasingly evident, affecting the neuropsychological development. Therefore, we advise follow-up programs are expanded to capture CNS involvement in larger, international patient cohorts, to incorporate our findings in the counselling of parents before the start of treatment, and to include the brain as an additional target in the development of next-generation therapeutic strategies for classic infantile Pompe disease. WHAT THIS PAPER ADDS: In our long-term survivors treated intravenously with enzyme replacement therapy, we found slowly progressive symmetric white-matter abnormalities. Cognitive development varied from stable and normal to declines towards intellectual disabilities.

AB - AIM: We investigated the validity of the Gait Outcomes Assessment List (GOAL), as an assessment of gait function in children with cerebral palsy (CP). METHOD: We studied a prospective cohort of 105 children with CP (Gross Motor Function Classification System [GMFCS] levels I-III; 65 males, 40 females; mean [SD] age 11y 11mo [3y 5mo], range 6-20y), who attended gait assessment over a 10-month period. Parents completed the GOAL, Functional Mobility Scale (FMS), and Functional Assessment Questionnaire (FAQ) during their child's gait evaluation. Ninety children completed instrumented gait analysis (IGA). Total GOAL and domain scores, Gait Profile Score (GPS), and Gait Variable Scores were calculated. RESULTS: The total GOAL discriminated between GMFCS levels (mean [SD] GMFCS level I, 72.5 [12.7]; GMFCS level II, 61.4 [13.0]; GMFCS level III, 38.8 [10.6]; [F2,97 =42.4, p<0.001]). Moderate correlations were found between total GOAL and FMS (5m and 50m r=0.59; 500m r=0.66) and FAQ walking (r=0.77) and activities list (r=0.75, p<0.01). There was a moderate negative correlation between total GOAL and GPS (r=-0.59) and gait appearance domain and GPS (r=-0.52, p<0.01). INTERPRETATION: The GOAL is a valid assessment of gait function in ambulant children with CP. It has the potential to improve understanding of the child's and parents' priorities and thus, in conjunction with IGA, provide a more balanced assessment across the domains of the World Health Organization's International Classification of Functioning, Disability and Health. WHAT THIS PAPER ADDS: The Gait Outcomes Assessment List (GOAL) can discriminate between Gross Motor Function Classification System levels. The GOAL correlates with standard functional assessments and gait analysis. Used with gait analysis, the GOAL provides comprehensive assessment across all International Classification of Functioning, Disability and Health domains.

AB - The hydraulic integrity of aquitards is generally assumed and relies on a few core-scale permeability measurements, drill-stem tests, or textbook values. This approach is because hydraulic data across the full aquitard thickness is generally lacking. Proper assessment of aquitard integrity should be studied at the formation (spanning its entire thickness at a single point) or regional (formation properties at multiple locations throughout the basin) scale. One formation-scale approach uses environmental tracers and advection-dispersion modeling to constrain fluid flow rates. This study demonstrates the use of helium concentrations in quartz as a method of constraining the rate of fluid flow in a 520-m thick aquitard in the Gunnedah Basin, NSW, Australia. Quartz was separated from existing core samples in the Watermark and Porcupine Formations at depths from 750 to 1200 m. The helium was released from these samples by heating and select samples were impregnated with helium to determine the rate of helium diffusion through the quartz. One-dimensional advection-dispersion modeling of the helium profile accounting for diffusive helium exchange between quartz and pore water revealed, that (1) vertical fluid velocity has been on the order of 0.02 mm/year or less for tens to thousands of years, (2) helium is in equilibrium between quartz and pore water, and (3) the helium profile is transient indicating that helium concentrations in the underlying Maules Creek Formation has varied over geological time. Further modeling identified aquitard conditions (thickness and temperature) for which equilibrium exists, a precondition for deriving formation-scale permeability.

AB - BACKGROUND: The theoretical framework of the current study is based on mediated learning experience (MLE) theory, which is similar to the scaffolding concept. The main question of the current study was to what extent mother-child MLE strategies affect psychological resilience and cognitive modifiability of boys with learning disability (LD). Secondary questions were to what extent the home environment, severity of boy's LD, and mother's attitude towards her child's LD affect her MLE strategies and consequently the child's psychological resilience and cognitive modifiability. AIMS: The main objectives of this study were the following: (a) to investigate the effects of mother-child MLE strategies on psychological resilience and cognitive modifiability among 7- to 10-year-old boys with LD, (b) to study the causal effects of distal factors (i.e., socio-economic status [SES], home environment, severity of child's LD, mother's attitude towards LD) and proximal factors (i.e., MLE strategies) on psychological resilience and cognitive modifiability. METHODS: A sample of mother-child dyads (n = 100) were videotaped during a short teaching interaction. All children were boys diagnosed as children with LD. The interaction was analysed for MLE strategies by the Observation of Mediation Interaction scale. Children were administered psychological resilience tests and their cognitive modifiability was measured by dynamic assessment using the Analogies subtest from the Cognitive Modifiability Battery. Home environment was rated by the Home Observation for Measurement of the Environment (HOME), and mothers answered a questionnaire of attitudes towards child's LD. RESULTS: The findings showed that mother-child MLE strategies, HOME, and socio-economic level contributed significantly to prediction of psychological resilience (78%) and cognitive modifiability (51%). Psychological resilience was positively correlated with cognitive modifiability (Rc = 0.67). Structural equation modelling analysis supported, in general, the hypotheses about the causal effects of distal and proximal factors of psychological resilience and cognitive modifiability. CONCLUSION: The findings validate and extend the MLE theory by showing that mother-child MLE strategies significantly predict psychological resilience and cognitive modifiability among boys with LD. Significant correlation between psychological resilience and cognitive modifiability calls for further research exploring the role of MLE strategies in development of both. PMID- 29573412 TI - Improved squalene production through increasing lipid contents in Saccharomyces cerevisiae. AB - Squalene, a valuable acyclic triterpene, can be used as a chemical commodity for pharmacology, flavor, and biofuel industries. Microbial production of squalene has been of great interest due to its limited availability, and increasing prices extracted from animal and plant tissues. Here we report genetic perturbations that synergistically improve squalene production in Saccharomyces cerevisiae. As reported previously, overexpression of a truncated HMG-CoA reductase 1 (tHMG1) led to the accumulation 20-fold higher squalene than a parental strain. In order to further increase squalene accumulation in the tHMG1 overexpressing yeast, we introduced genetic perturbations-known to increase lipid contents in yeast-to enhance squalene accumulation as lipid body is a potential storage of squalene. Specifically, DGA1 coding for diacylglycerol acyltranferase was overexpressed to enhance lipid biosynthesis, and POX1 and PXA2 coding for acyl-CoA oxidase and a subunit of peroxisomal ABC transporter were deleted to reduce lipid beta oxidation. Simultaneous overexpression of tHMG1 and DGA1 coding for rate-limiting enzymes in the mevalonate and lipid biosynthesis pathways led to over 250-fold higher squalene accumulation than a control strain. However, deletion of POX1 and PXA2 in the tHMG1 overexpressing yeast did not improve squalene accumulation additionally. Fed-batch fermentation of the tHMG1 and DGA1 co-overexpressing yeast strain resulted in the production of squalene at a titer of 445.6 mg/L in a nitrogen-limited minimal medium. This report demonstrates that increasing storage capacity for hydrophobic compounds can enhance squalene production, suggesting that increasing lipid content is an effective strategy to overproduce a hydrophobic molecule in yeast. PMID- 29573413 TI - Herpetiform pemphigus with characteristic transmission electron microscopic findings of various-sized ballooning vacuoles in keratinocytes without acantholysis. AB - We report a unique case of a Japanese woman with herpetiform pemphigus (HP) who had IgG autoantibodies reactive with nondesmosomal sites of keratinocytes and presented characteristic transmission electron microscopic (TEM) findings of various-sized vacuoles in keratinocytes without acantholysis. The patient presented with pruritic annular oedematous erythemas with small blisters lining the margins on the trunk and extremities. Histopathological examinations showed intraepidermal blisters with prominent infiltrations of eosinophils. Direct and indirect immunofluorescence tests revealed the presence of in vivo bound and circulating IgG autoantibodies to the keratinocyte cell surfaces. However, enzyme linked immunosorbent assays for desmoglein (Dsg) 1, Dsg3 and desmocollins 1-3 showed negative results. Immunoblotting using the full-length human Dsg1 recombinant protein showed a positive band. TEM examination showed various-sized vacuoles squashing the nuclei in many keratinocytes, resulting in rupture of the cells. Immunoelectron microscopic examination revealed IgG deposition over the entire keratinocyte cell surfaces, which spared the desmosomes. IgG antibodies were also present on the inside walls of the vacuoles around the nuclei of keratinocytes and on the cell surfaces of infiltrating eosinophils. This patient also had marked eosinophilia and high levels of thymus and activation-regulated chemokine and interleukin-5 in the serum. These results indicated a novel autoantigen on the nondesmosomal keratinocyte cell surfaces and the pathogenesis of bullous spongiotic change with inflammation in HP.

AB - Twelve years ago, FDI World Dental Federation and Unilever Oral Care began a partnership to raise awareness of oral health globally. This aim reflects FDI's mission to "lead the world to optimal oral health", and one of the goals set by the Unilever Sustainable Living Plan "to improve health and well-being for more than 1 billion" by 2020. This partnership has developed a series of public health programmes to improve the brushing habits of targeted populations through health promotion and educational campaigns worldwide. Building on the success of the first two phases of the partnership, the third phase (Phase III), named Brush Day & Night, aimed to educate children in brushing twice-daily with fluoride toothpaste via a 21 Day school programme. This article reports the main outcomes of the past 12 years of this partnership, in particular the key outreach and figures of Phase III evaluation. School programmes were implemented in 10 countries, where local teams collected data from children aged between 2 and 12 years to monitor their oral health behaviours using specific indicators. In addition to the school programme, the World Oral Health Day was used as a vehicle to convey oral health awareness to influential governing bodies and the public. As a result, over 4 million people were directly reached by the programme in 2016. PMID- 29573415 TI - Is grit relevant to well-being and strengths? Evidence across the globe for separating perseverance of effort and consistency of interests. AB - OBJECTIVE: Researchers conceptualize grit as the combination of two facets: perseverance of effort and consistency of interests toward long-term goals. We tested the reliability of grit facet scores across the globe and examined how differently each grit facet related to well-being and personality strengths. METHOD: An international sample of 7,617 participants from six of the seven continents (excluding Antarctica) completed an online survey. RESULTS: Confirmatory factor analyses and omega reliability coefficients indicated that the 12 items from the original Grit Scale were multidimensional and reliably measured perseverance of effort and consistency of interests. Concurrent validity analyses showed that perseverance of effort was moderately to strongly related to subjective well-being, beliefs about well-being, and personality strengths, whereas consistency of interests had weak or negative correlations with these outcomes. The stronger relations with perseverance of effort were replicated across seven regions of the world. The presence of overall grit was supported in individualistic countries, but not collectivistic countries (i.e., those in Latin America and Asia). CONCLUSIONS: We discuss the multidimensionality of grit, including a conceptual understanding of overall grit and how it may differ across cultures. We suggest well-being and strengths researchers study grit facets separately due to their differential validity. PMID- 29573416 TI - Is cricothyroid muscle twitch predictive of the integrity of the EBSLN in Thyroid Surgery? AB - OBJECTIVE: Cricothyroid (CT) muscle twitch inspection with neurostimulation is a widely accepted method to identify the external branch of the superior laryngeal nerve (EBSLN) and its integrity in thyroid surgery. However, there has been no large-scale research to evaluate the diagnostic values of CT muscle twitch inspection based on postoperative electromyography (EMG) results, which are considered the gold standard. In this study, we aimed to demonstrate the diagnostic value of CT muscle twitch inspection based on postoperative EMG. STUDY DESIGN: Prospective cohort study. METHODS: A total of 454 patients underwent primary thyroid surgery. Among them, 55 patients were excluded because of preoperative vocal fold palsy, problems with the stimulator, or refusal to participate in the EMG study. Finally, 399 patients were prospectively enrolled in this study. Intraoperatively, CT muscle twitch was inspected with neurostimulation. Bilateral EMG examination of the CT muscle was performed 2 to 3 months postoperatively in all patients. RESULTS: A total of 712 EBSLNs at risk were analyzed in this study. Of these, 21 (2.9%) nerves were visually identified, and positive CT muscle twitch by neurostimulation was observed in 694 (97.5%). Normal results on postoperative EMG of the CT muscle were reported in 657 (92.3%). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 97.7%, 5.5%, 92.5%, and 16.7%, respectively. CONCLUSION: CT muscle twitch inspection could be a useful intraoperative tool to determine EBSLN integrity considering its high sensitivity and PPV. However, the test may not completely replace EMG for evaluating EBSLN integrity due to its low specificity and NPV. LEVEL OF EVIDENCE: 2b. Laryngoscope, 2654-2661, 2018. PMID- 29573417 TI - What do anti-Toxoplasma gondii IgA and IgG subclasses in human saliva indicate? AB - Diagnostic tests for toxoplasmosis are based on serological techniques due to their high sensitivity. Some IgG subclasses are related to clinical outcome in the congenital form. In this work, we determined the levels of IgG, IgA, IgG1, IgG2, IgG3 and IgG4 anti-Toxoplasma gondii antibodies in paired saliva and serum samples from 91 women by indirect ELISA using a crude extract of the RH strain. The levels of IgA, IgG2, IgG3 and IgG4 antibodies and, to a lesser extent, IgG1 did not correlate between saliva and serum, that is, most cases that were positive for one Ig class in a sample were negative or very low in the other, and vice versa. We also observed that most samples of saliva that were positive for one IgG subclass were also positive for at least 2 of the other 3; this contrasted with findings in serum, wherein each person was positive almost exclusively for one subclass, as demonstrated before by us and other researchers. Although these findings are disappointing for the use in diagnosis, the richer response in saliva might indicate local exposure to T. gondii antigens without systemic infection; thus, saliva might be reflecting a local (protective?) response against this protozoan. PMID- 29573418 TI - Short- and long-term outcomes of oropharyngeal cancer care in the elderly. AB - OBJECTIVE: To examine associations between pretreatment variables, short-term and long-term swallowing and airway impairment, and survival in elderly patients (age > 65 years) treated for oropharyngeal squamous cell cancer (SCCA). STUDY DESIGN: Retrospective analysis of Surveillance, Epidemiology, and End Results (SEER) Medicare data. METHODS: Longitudinal data from 666 patients diagnosed with oropharyngeal SCCA from 2004 to 2007 were evaluated using cross-tabulations, multivariate logistic regression, and survival analysis. RESULTS: Dysphagia (odds ratio [OR] = 1.3, 1.0-1.7), esophageal stricture (OR = 5.5, 2.6-11.9), and airway obstruction (OR = 1.6, 1.1-2.2) increased 1 year after treatment. The odds of airway obstruction, esophageal stricture, and pneumonia increased over subsequent years, with significantly increased risk at 5 years for airway obstruction (OR = 3.0, 1.4-6.4), pneumonia (OR = 4.5, 1.8-11.2), and stricture (OR = 5.5, 1.8 17.6). Pretreatment dysphagia was a significant predictor of long-term dysphagia, airway obstruction, and pneumonia. Chemoradiation, advanced stage disease, high volume hospital care, male sex, and salvage surgery were significant predictors of long-term gastrostomy use. Long-term dysphagia, gastrostomy or tracheostomy dependence, weight loss, airway obstruction, and pneumonia were associated with poorer survival, with tracheostomy dependence (hazard ratio [HR] = 2.2, 1.7-2.9) and pneumonia (HR = 2.0, 1.7-2.4) associated with the greatest risk of late mortality. CONCLUSION: Airway and swallowing impairment is common after treatment of oropharyngeal SCCA in elderly patients, increases over time, and is associated with poorer survival. Patients with pretreatment dysphagia, advanced stage disease, initial treatment with chemoradiation, and salvage surgery represent a high-risk group with an increased risk of disability and death.

PMID- 29573419 TI - Should surgery be part of the multimodality treatment for stage IIIB non-small cell lung cancer? AB - BACKGROUND: Traditionally, treatment for stage IIIB (T4N2M0 and T1-4N3M0) NSCLC consists in definitive chemoradiation. Surgery is used only anecdotally. Here, we studied outcome for patients treated with multimodality including surgery. METHODS: Patients who underwent surgery for stage IIIB between 2000 and 2015 were retrospectively reviewed and data analyzed. Patients were selected for surgery if they would tolerate multimodality treatment, the tumor was deemed upfront resectable, and N2-N3 involvement was limited to a non-bulky single site. Survival was calculated from the date of surgery until last follow-up. Univariate and multivariate analysis were performed to identify prognostic factors. RESULTS: During the study period, 5416 patients underwent resection for NSCLC in our center. Sixty patients (1%) had clinical stage IIIB. Thirty-two patients had T4N2 NSCLC involving the carina and/or superior vena cava (n = 25, 78%), left atrium (n = 5, 16%), or other (n = 2, 6%). Half of the 28 patients with N3-disease had supraclavicular node involvement. Pneumonectomy was performed in 27 patients (45%). Twenty-nine patients (48%) had induction therapy, with chemotherapy alone. Adjuvant therapy was administered to 52 patients (87%), mostly chemoradiation. Complete resection rate was 92%. Post-operative mortality was 3%. Three- and 5 year overall survivals were 51% and 39%, respectively. Multivariate analysis identified incomplete resection (P = 0.008) and absence of adjuvant treatment (P = 0.032) as poor survival prognostic factors. CONCLUSIONS: Surgery can be considered as a component of multimodality therapy in highly selected patients with stage IIIB NSCLC based on encouraging 5-year survival of 39%. PMID- 29573421 TI - Extracapsular dissection for warthin tumors despite the risk of ipsilateral metachronous occurrence. AB - OBJECTIVES/HYPOTHESIS: The ideal extent of surgical intervention for cystadenolymphomas of the parotid gland remains a matter of controversy. The aim of our study was to assess the surgical outcome after extracapsular dissection for cystadenolymphomas of the parotid gland. A further purpose of this study was to examine how the number of primary cystadenolymphomas or the size of the primary lesion influences the possibility of an ipsilateral metachronous tumor occurrence. STUDY DESIGN: Retrospective clinical study. METHODS: A retrospective evaluation of the records was carried out for all patients treated for cystadenolymphomas of the parotid gland by means of extracapsular dissection at a tertiary referral center between 2000 and 2012. RESULTS: Three hundred twenty seven patients were included in the study. Our analysis detected an overall occurrence rate of ipsilateral metachronous tumors of 3.1% (10/327) with a mean follow-up of 108.4 months. A significant difference in the rate of metachronous lesions between unilocular (1.7%) and multilocular (11.6%) tumors could be detected (chi2 (1) = 7.342, P < .001). Our analysis was not able to find any significant influence of the maximal tumor size on the rate of metachronous tumors (chi2 (1) = 0.634, P = .426). CONCLUSIONS: One of the most controversial issues in the treatment of cystadenolymphomas of the parotid gland concerns the question of which is the best therapeutic approach to be taken in such patients. Our analysis was able to demonstrate the benefits of extracapsular dissection in the management of solitary as well as carefully selected multicentric cystadenolymphomas with a consistently acceptable surgical outcome.

AB - BACKGROUND: To evaluate the effect of distilled water, ethylenediaminetetraacetic acid (EDTA), phosphoric acid and maleic acid on Biodentine regarding surface topography, microhardness and push-out bond strength (POBS). METHODS: Fifty-two cylindrical shaped Biodentine specimens were divided into groups: control (distilled water); EDTA (17% EDTA); PA (37% phosphoric acid); and MA (7% maleic acid). Surfaces were evaluated by topographic analysis and Vickers microhardness test. Topographic changes were evaluated qualitatively and microhardness was statistically analyzed by Kruskal-Wallis test. Forty mandibular molars were used to simulate clinical conditions. The crowns were removed and a perforation was created at the furcal floor. The Biodentine was packed into the root perforations and the roots were divided into four groups (DW, EDTA, PA, MA). Samples were stored and subjected to interfacial analysis. POBS data were analyzed by Kruskal Wallis and Dunn tests. RESULTS: Ethylenediaminetetraacetic acid, MA and PA changed the morphology of the Biodentine surface. PA showed microhardness similar to distilled water (P > 0.05), while MA and EDTA demonstrated reduced values when compared with PA (P < 0.05). PA improved the POBS of Biodentine in comparison with the control. CONCLUSIONS: Changes in the topography, microhardness and POBS of Biodentine are associated with irrigant agent used. PMID- 29573423 TI - Toxic money or paid altruism: the meaning of payments for identity-release gamete donors. AB - Public discourses commonly frame gamete, organ and other forms of bodily donation as altruistic 'gifts'. However, despite on-going debates about the ethics of payments to donors, few studies have examined the views of donors themselves regarding the meaning of payments and their compatibility (or not) with understandings of these practices as gifts. This article addresses this issue, analysing 24 in-depth interviews with UK identity-release gamete donors. It was crucial to all participants that their donation be viewed as fundamentally other oriented, motivated by the desire to help others. However, whilst egg donors often accommodated payment within this narrative, male participants explained that any money would taint the gift they had given. I argue that sperm donors faced particular challenges to incorporating payment within a gift narrative for two key reasons: first, sperm donors relied on a discourse of 'pure altruism', including absolute opposition between gifts and market exchange, in order to present their donation as other-oriented. In contrast, egg donors were also able to mobilise a discourse of relational giving to present their donations as a personal gift. Second, according to a continued stereotype of sperm donors as financially motivated students, their payments have already been culturally earmarked as side-line earnings. PMID- 29573424 TI - Estimating heat tolerance of plants by ion leakage: a new method based on gradual heating. AB - Heat tolerance of plants related to cell membrane thermostability is commonly estimated via the measurement of ion leakage from plant segments after defined heat treatment. To compare heat tolerance of various plants, it is crucial to select suitable heating conditions. This selection is time-consuming and optimizing the conditions for all investigated plants may even be impossible. Another problem of the method is its tendency to overestimate basal heat tolerance. Here we present an improved ion leakage method, which does not suffer from these drawbacks. It is based on gradual heating of plant segments in a water bath or algal suspensions from room temperature up to 70-75 degrees C. The electrical conductivity of the bath/suspension, which is measured continuously during heating, abruptly increases at a certain temperature TCOND (within 55-70 degrees C). The TCOND value can be taken as a measure of cell membrane thermostability, representing the heat tolerance of plants/organisms. Higher TCOND corresponds to higher heat tolerance (basal or acquired) connected to higher thermostability of the cell membrane, as evidenced by the common ion leakage method. The new method also enables determination of the thermostability of photochemical reactions in photosynthetic samples via the simultaneous measurement of Chl fluorescence. PMID- 29573425 TI - Cochlear implantation and auditory brainstem implantation in neurofibromatosis type 2. AB - OBJECTIVES/HYPOTHESIS: To report a series of patients with neurofibromatosis type 2 (NF2), where each patient underwent both cochlear implantation and auditory brainstem implantation for hearing rehabilitation, and to discuss factors influencing respective implant success. STUDY DESIGN: Retrospective case series. METHODS: Ten NF2 patients with both cochlear implantations and auditory brainstem implantations were retrospectively reviewed. Speech testing for auditory brainstem implants (ABIs) and cochlear implants (CIs) was performed separately. Scores at last follow-up were obtained for Iowa vowels and consonants, Northwestern University Children's Perception of Speech (NU-CHIPS), and City University of New York (CUNY) sentences. RESULTS: Mean age at time of implant was 37 years for cochlear implantation and 40 years for auditory brainstem implantation (P = .790, t test). Nine of 10 patients had a CI and ABI on contralateral sides, and one had both devices on the same side. Mean duration of deafness in the implanted ear was 4.3 years for both cochlear implantation and auditory brainstem implantation (P = .491, t test). Follow-up range was 1 to 28 years. CI performance on NU-CHIPS was 32% to 100%, and sound + lip-reading CUNY was 56% to 100%. Four patients experienced an eventual decline in CI function to unusable levels. ABI performance on NU-CHIPS was 40% to 80%, and sound + lip reading CUNY was 38% to 94%. There was no notable decline in ABI function over time. CONCLUSIONS: If the cochlear nerve is intact, cochlear implantation can be an effective strategy for hearing rehabilitation in NF2. However, a significant proportion experience a decline in CI performance related to growing vestibular schwannoma or tumor treatment. Auditory brainstem implantation remains the standard option for surgical hearing rehabilitation in NF2, but peak performance is generally lower than that achievable with cochlear implantation.

AB - Sample preparation is rapidly improving to fulfill the need for faster and more environmentally friendly alternatives. In this respect, ionic liquid-based dispersive liquid-liquid microextraction (IL-DLLME) is an interesting technique. However, it has not yet been evaluated for the analysis of postmortem samples, which are frequently analyzed in forensic toxicology. This study investigates the applicability of IL-DLLME coupled to liquid chromatography-tandem mass spectrometry (LC-MS/MS), for the analysis of benzodiazepines in postmortem blood of 11 forensic cases. The method was compared with a validated solid-phase extraction (SPE) method. Bland-Altman analysis was performed on 24 benzodiazepine measurements. Both methods gave comparable results, except for flurazepam and temazepam (>55% difference). A feasible explanation is high postmortem matrix variability that was not considered during IL-DLLME validation experiments. Another issue could be the use of a single nondeuterated SPE internal standard. Overall, IL-DLLME has proven its usability for the analysis of postmortem blood. PMID- 29573427 TI - Transgenerational phenotype aggravation in CAF-1 mutants reveals parent-of-origin specific epigenetic inheritance. AB - Chromatin is assembled by histone chaperones such as chromatin assembly factor CAF-1. We had noticed that vigor of Arabidopsis thaliana CAF-1 mutants decreased over several generations. Because changes in mutant phenotype severity over generations are unusual, we asked how repeated selfing of Arabidopsis CAF-1 mutants affects phenotype severity. CAF-1 mutant plants of various generations were grown, and developmental phenotypes, transcriptomes and DNA cytosine methylation profiles were compared quantitatively. Shoot- and root-related growth phenotypes were progressively more affected in successive generations of CAF-1 mutants. Early and late generations of the fasciata (fas)2-4 CAF-1 mutant displayed only limited changes in gene expression, of which increasing upregulation of plant defense-related genes reflects the transgenerational phenotype aggravation. Likewise, global DNA methylation in the sequence context CHG but not CG or CHH (where H = A, T or C) changed over generations in fas2-4. Crossing early and late generation fas2-4 plants established that the maternal contribution to the phenotype severity exceeds the paternal contribution. Together, epigenetic rather than genetic mechanisms underlie the progressive developmental phenotype aggravation in the Arabidopsis CAF-1 mutants and preferred maternal transmission reveals a more efficient reprogramming of epigenetic information in the male than the female germline. PMID- 29573428 TI - The effect of postoperative steroids on post-tonsillectomy pain and need for postoperative physician contact. AB - OBJECTIVES/HYPOTHESIS: Examine the effect of postoperative steroids on postoperative physician contacts and determine the hemorrhage rate for patients taking postoperative steroids. STUDY DESIGN: Retrospective review of medical records. METHODS: A retrospective review was performed of children undergoing tonsillectomies before and after the institution of a standard postoperative course of three doses of dexamethasone (0.5 mg/kg). Tylenol and ibuprofen were also used for all patients, with oxycodone given as a rescue medication for children >=6 years of age. Postoperative hemorrhage rate (all visits to the emergency department [ED] with concern for post-tonsillectomy hemorrhage), return to the ED for pain, and phone calls to the office for pain were recorded. RESULTS: A total of 1,200 children were included (300 without and 900 with steroids); there was no difference in age or weight between groups. Overall, the mean age was 6.6 +/- 2.1 years and the hemorrhage rate was 7%. Parental phone calls decreased from 23.3% prior to steroid use to 14.7% after (P < .001), and post-tonsillectomy hemorrhage rates decreased from 9.7% to 5.7% (P = .02). There was no difference in ED visit rates (P = 0.70). Regression analysis showed that bleeding increased by 4% (95% confidence interval [CI]: 1%-13%) for each increasing year of age (P < .001), whereas postoperative steroids decreased hemorrhage rates by 7% (95% CI: 1%-9% reduction) (P = .013). The risk of a phone call increased by 2% for each year of age; postoperative steroids decreased phone calls by 9% (P < .001). There were no steroid-related complications within 1 month of surgery. CONCLUSIONS: A short course of postoperative steroids decreased the number of postoperative phone calls for pain by 9% after tonsillectomy, and decreased the risk of postoperative tonsillectomy hemorrhage by 7%.

AB - OBJECTIVE: Nontechnical skills (NTS) are essential to emergency crisis management. Due to the rarity of true emergencies, they are challenging to teach and assess within a competency-based curriculum. Our purpose is to evaluate the utility of the Non-Technical Skills in Surgery (NOTSS) scale in NTS assessment in simulated otolaryngology and head and neck surgery (OTO-HNS) emergencies and identify common challenges that residents encounter. METHODS: Mixed methods analysis of 15 junior OTO-HNS resident teams in four simulated emergency scenarios. Six raters rated resident NTS performance using the NOTSS score. Constructivist-grounded theory was used to analyze scenario video transcripts to identify areas of learner difficulty to guide future simulation development. RESULTS: Residents scored highest in situational awareness and lowest in leadership domains. Raters showed good consistency and reliability overall (Cronbach's alpha = 0.885). There was no statistical difference in ratings between surgical experts and nonexperts. Qualitative analysis demonstrated challenges with closed-loop communication and handling transitions of leadership with the scenarios. CONCLUSION: Simulation-based training is an effective modality to teach NTS in crisis resource management. The NOTSS rating scale is a reliable instrument for assessing NTS in simulated OTO-HNS emergencies. Incorporating the NOTSS scale for NTS assessment within a competency-based curriculum is recommended. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:2301-2306, 2018. PMID- 29573430 TI - Contribution of adventitious vs initial roots to growth and physiology of black spruce seedlings. AB - Black spruce (Picea mariana [Mill.] BSP) is a boreal tree species characterized by the formation of an adventitious root system. Unlike initial roots from seed germination, adventitious roots gradually appear above the root collar, until they constitute most of mature black spruce root system. Little is known about the physiological role they play and their influence on tree growth relative to initial roots. We hypothesized that adventitious roots present an advantage over initial roots in acquiring water and nutrients. To test this hypothesis, the absorptive capacities of the two root systems were explored in a controlled environment during one growing season. Black spruce seedlings were placed in a double-pot system allowing irrigation (25 and 100% water container capacity) and fertilization (with or without fertilizer) inputs independent to initial and adventitious roots. After 14 weeks, growth parameters (height, diameter, biomass), physiology (net photosynthetic rate, stomatal conductance, shoot water potential) and nutrient content (N, P, K, Ca and Mg foliar content) were compared. Most measured parameters showed no difference for the same treatment on adventitious or initial roots, except for root biomass. Indeed, fertilized black spruce seedlings invested heavily in adventitious root production, twice as much as initial roots. This was also the case when adventitious roots alone were irrigated, while seedlings with adventitious roots subjected to low irrigation produced initial root biomass equivalent to that of adventitious roots. We conclude that black spruce seedlings perform equally well through adventitious and initial roots, but if resources are abundant, they strongly promote development of adventitious roots. PMID- 29573431 TI - Multiscale patterns and drivers of arbuscular mycorrhizal fungal communities in the roots and root-associated soil of a wild perennial herb. AB - Arbuscular mycorrhizal (AM) fungi form diverse communities and are known to influence above-ground community dynamics and biodiversity. However, the multiscale patterns and drivers of AM fungal composition and diversity are still poorly understood. We sequenced DNA markers from roots and root-associated soil from Plantago lanceolata plants collected across multiple spatial scales to allow comparison of AM fungal communities among neighbouring plants, plant subpopulations, nearby plant populations, and regions. We also measured soil nutrients, temperature, humidity, and community composition of neighbouring plants and nonAM root-associated fungi. AM fungal communities were already highly dissimilar among neighbouring plants (c. 30 cm apart), albeit with a high variation in the degree of similarity at this small spatial scale. AM fungal communities were increasingly, and more consistently, dissimilar at larger spatial scales. Spatial structure and environmental drivers explained a similar percentage of the variation, from 7% to 25%. A large fraction of the variation remained unexplained, which may be a result of unmeasured environmental variables, species interactions and stochastic processes. We conclude that AM fungal communities are highly variable among nearby plants. AM fungi may therefore play a major role in maintaining small-scale variation in community dynamics and biodiversity. PMID- 29573432 TI - Molecular characterization and polymorphisms of butyrylcholinesterase in cynomolgus macaques. AB - BACKGROUND: Butyrylcholinesterase (BChE), an enzyme essential for drug metabolism, has been investigated as antidotes against organophosphorus nerve agents, and the efficacy and safety have been studied in cynomolgus macaques. BChE polymorphisms partly account for variable BChE activities among individuals in humans, but have not been investigated in cynomolgus macaques. METHODS: Molecular characterization was carried out by analyzing primary sequence, gene, tissue expression, and genetic variants. RESULTS: In cynomolgus and human BChE, phylogenetically closely related, amino acid residues important for enzyme function were conserved, and gene and genomic structure were similar. Cynomolgus BChE mRNA was most abundantly expressed in liver among the 10 tissue types analyzed. Re-sequencing found 26 non-synonymous genetic variants in 121 cynomolgus and 23 rhesus macaques, indicating that macaque BChE is polymorphic, although none of these variants corresponded to the null or defective alleles of human BChE. CONCLUSIONS: These results suggest molecular similarities of cynomolgus and human BChE.

AB - As part of a reorganisation of the delivery of health care in Denmark therapies for chronic medical conditions are moved out of hospitals and disease-specific patient education programmes instituted to train patients to assume responsibility for treating their disease at home, that is, perform tasks and functions traditionally done by healthcare professionals. Drawing on video recordings (90:25h) from a programme for self-management of end-stage renal disease through automated home peritoneal dialysis, the study employs conversation analysis to examine nurses' instructional practices for providing patients with the necessary knowledge, skill and competences. Showing training to rely on an error-based monitoring strategy, the study demonstrates that rather than solely waiting for random errors to emerge, nurses on occasion steer patients towards specific errors to bring about particular instructional opportunities. Surprising given the seriousness of the therapy, this elicitation of error is shown to reflect a deliberate instructional choice; nurses promote select errors to impart patients with an understanding of the procedural logic behind the therapy and medical technology. The study argues that training patients for chronic disease self-management and providing them with a proficiency level, normally associated with certified professionals, necessitates pushing patients beyond what is strictly accurate and exposing them to medically delicate events. PMID- 29573435 TI - Comparison of cricothyroid approximation and glottoplasty for surgical voice feminization in male-to-female transsexuals. AB - OBJECTIVE: To compare voice feminization and quality of life (QoL) of Male-to Female Transsexuals (MtF Ts) after cricothyroid approximation (CTA) or glottoplasty (GL). STUDY DESIGN: Retrospective study. METHODS: Fifty-three MtF Ts were studied between 2007 and 2016. Voice assessment was based on fundamental frequency (F0 ), perceptual rating on GBRAS Hirano scale (Grade, Breathiness, Roughness, Asthenia, Strain), QoL related to voice on the Voice Handicap Index-10 Spanish validated version (VHI-10 Sv) and self-perceived femininity of the voice (SpFv), and overall satisfaction with the surgical technique (Sst) on a visual analogue scale (VAS). Demographic data and complications related to surgery were also recorded. RESULTS: Twenty-eight MtF Ts underwent CTA and 23 GL. The mean age was 35 years. The median follow-up period was 40 months. Mean F0 improved after surgery for both groups, but this increase was 27 Hz higher after GL than after CTA (P < 0.05). After CTA, F0 decreased over time but remained stable after GL. The GBRAS score did not change after CTA; the roughness item and total score increased from 0 to 1 after GL (P < 0.05). VHI-10 Sv scores decreased similarly in both groups. SpFv increase was higher after GL. The Sst was mild and similar in both groups. One case of severe dysphonia (4%) resulting from a big and fibrous sinequia occurred after GL. CONCLUSION: Both CTA and GL increase F0 , improving QoL in MtF Ts. However, F0 increase is higher and more long-lasting after GL. More risk of postoperative roughness is described after GL.

AB - BACKGROUND: Anxiety sensitivity (AS) reflects an individual's belief that experiencing anxiety will cause illness or embarrassment, and may be a reason individuals self-medicate with alcohol. Harsh or indulgent parenting could contribute to the development of AS. We examined the direct and indirect associations between parenting styles and alcohol-related variables through AS and impaired control over drinking (IC; i.e., perceived failure to adhere to limits on alcohol consumption in the future). METHODS: A multiple-group structural equation model with 614 university students (344 men; 270 women) was examined. Structural invariance tests were conducted to evaluate moderation by gender. We used a bias corrected bootstrap technique to obtain the mediated effects. RESULTS: Father authoritarianism and mother permissiveness were directly linked to AS among women, whereas father permissiveness was directly linked to AS among men. This suggests unique parental influences based on gender regarding AS. While AS was directly linked to alcohol-related problems for both men and women, several gender-specific associations were found. AS was directly linked to IC for men but not for women. For men, father permissiveness was directly related to AS, and AS mediated the indirect link between father permissiveness and IC along both the heavy episodic drinking and alcohol-related problems pathways. Similar to other internalizing constructs (e.g., neuroticism and depression), higher AS was directly associated with less heavy episodic drinking but more alcohol-related problems. CONCLUSIONS: Our findings highlight the dangers of AS for men as an important correlate of under-controlled drinking behaviors. Additionally, permissive parenting of the same-gender parent was associated with AS, which is consistent with the gender-matching hypothesis. Together, these results underscore the importance of measuring the independent influence of both parents. PMID- 29573436 TI - Effects of ethrel, 1-MCP and modified atmosphere packaging on the quality of 'Wonderful' pomegranates during cold storage. AB - BACKGROUND: Pomegranate (Punica granatum) is a non-climacteric fruit susceptible to chilling injury (CI) at temperatures below 5 degrees C. To understand the influences of ethylene and modified atmosphere on CI physiological disorders of pomegranate, exogenous ethrel (0.5, 1 and 1.5 ug L-1 ) treatments, 1 methylcyclopropene (1-MCP) (1 uL L-1 ) exposure, packaging in a modified atmosphere (MAP) (XTendTM bags; StePac, Sao Paulo, Brazil), a MAP/1-MCP combination, and packaging in macro-perforated bags (MPB) were applied. The treated fruits were cold stored (2 +/- 1 degrees C; 85% relative humidity) and sampled during 120 + 3 days at 20 degrees C. RESULTS: During cold storage, CI symptoms started at 20 days in MPB and at 60 days for all exogenous ethylene treatments, and were delayed to 120 days in MAP, 1-MCP and MAP/1-MCP treatments. MPB and ethylene treatments induced significant electrolyte leakage, oxidative damage, lipid peroxidation, ethylene and CO2 production, and 1-aminocyclopropane 1-carboxylic acid oxidase activity, without any change in total soluble solids, titratable acidity or skin and aril colours. Conversely, MAP by itself, or in combination with 1-MCP application, effectively delayed CI symptoms. CONCLUSION: During long-term cold storage of this non-climacteric fruit, ethrel application induced endogenous ethylene biosynthesis, accelerating the appearance of CI symptoms in contrast to the observations made for MAP and 1-MCP treatments.

AB - OBJECTIVE: Current studies on the association between bacteria and chronic rhinosinusitis (CRS) have relied solely on microbiological culture, which can sometimes be negative due to prior antibiotic therapy or lack of transport media. The objective of the study was to understand whether bacteria are associated with culture-negative cases. METHODS: We investigated 20 cases of CRS undergoing functional endoscopic sinus surgery by both culture and 16S rRNA gene polymerase chain reaction (PCR) followed by sequencing. The disease severity was assessed using Sino-nasal Outcome Test-22 (SNOT-22) scoring preoperatively. RESULTS: Of the 20 cases studied, only five were culture-positive. Bacteria were detected in all 15 culture-negative cases by 16S rRNA gene PCR. Sequencing indicated that Staphylococcus is the dominant group, followed by Enterobacter and Pseudomonas. In two cases, from which Pseudomonas was detected, SNOT-22 scores were above 80, indicating high disease severity. CONCLUSION: 16S rRNA gene PCR, followed by sequencing, would help the clinician understand the association between bacteria and CRS. Molecular detection and identification of bacteria would help the clinician better predict the outcome and plan further management accordingly. LEVEL OF EVIDENCE: NA.

PMID- 29573438 TI - Clinical application of chromosomal microarray analysis for the prenatal diagnosis of chromosomal abnormalities and copy number variations in fetuses with congenital heart disease. AB - OBJECTIVES: This study aimed to determine chromosomal abnormalities and copy number variations (CNVs) in fetuses with congenital heart disease (CHD) by chromosomal microarray analysis (CMA). METHODS: One hundred and ten cases with CHD detected by prenatal echocardiography were enrolled in the study; 27 cases were simple CHDs, and 83 were complex CHDs. Chromosomal microarray analysis was performed on the Affymetrix CytoScan HD platform. All annotated CNVs were validated by quantitative PCR. RESULTS: Chromosomal microarray analysis identified 6 cases with chromosomal abnormalities, including 2 cases with trisomy 21, 2 cases with trisomy 18, 1 case with trisomy 13, and 1 unusual case of mosaic trisomy 21. Pathogenic CNVs were detected in 15.5% (17/110) of the fetuses with CHDs, including 13 cases with CHD-associated CNVs. We further identified 10 genes as likely novel CHD candidate genes through gene functional enrichment analysis. We also found that pathogenic CMA results impacted the rate of pregnancy termination. CONCLUSIONS: This study shows that CMA is particularly effective for identifying chromosomal abnormalities and CNVs in fetuses with CHDs as well as having an effect on obstetrical outcomes. The elucidation of the genetic basis of CHDs will continue to expand our understanding of the etiology of CHDs. PMID- 29573439 TI - Commentary on De Genna et al.

PMID- 29573440 TI - Do Electronic Cigarettes Have a Role in Tobacco Cessation? AB - Tobacco use continues to be a major cause of morbidity and mortality. Even with behavioral and pharmacologic treatment, long-term tobacco cessation rates are low. Electronic nicotine delivery systems, commonly referred to as electronic cigarettes or e-cigarettes, are increasingly used for tobacco cessation. Because e-cigarettes are widely used in this setting, health care professionals need to know if they are safe and effective. The purpose of this article is to review literature regarding use of e-cigarettes as a tool for tobacco cessation in patients who are ready to quit, as well as those who are not ready to quit, along with some selected patient populations. The safety and clinical implications of e cigarette use are also reviewed. Small, short-term studies assessing smokers' use of e-cigarettes suggest that e-cigarettes may be well tolerated and modestly effective in achieving abstinence. High-quality studies are lacking to support e cigarettes use for cessation in patients with mental health issues. One small prospective cohort study concluded that patients with mental health issues reduced cigarette use with e-cigarette use. Although one study found that patients with cancer reported using e-cigarettes as a tobacco-cessation strategy, e-cigarettes were not effective in supporting abstinence 6 and 12 months later. Additional research is needed to evaluate the use of e-cigarettes for smoking cessation in patients with pulmonary diseases. No data exist to describe the efficacy of e-cigarettes for smoking cessation in pregnant women. Although study subjects report minimal adverse effects with e-cigarettes and the incidence of adverse effects decreases over time, long-term safety data are lacking. Health care providers should assess e-cigarette use in their patients as part of the tobacco cessation process. PMID- 29573441 TI - Contemporary microbiology and identification of Corynebacteria spp. causing infections in human. AB - : The Corynebacterium is a genus of bacteria of growing clinical importance. Progress in medicine results in growing population of immunocompromised patients and growing number of infections caused by opportunistic pathogens. A new infections caused by new Corynebacterium species and species previously regarded as commensal micro-organisms have been described. Parallel with changes in Corynebacteria infections, the microbiological laboratory diagnostic possibilities are changing. But identification of this group of bacteria to the species level remains difficult. In the paper, we present various manual, semi automated and automated assays used in clinical laboratories for Corynebacterium identification, such as API Coryne, RapID CB Plus, BBL Crystal Gram Positive ID System, MICRONAUT-RPO, VITEK 2, BD Phoenix System, Sherlock Microbial ID System, MicroSeq Microbial Identification System, Biolog Microbial Identification Systems, MALDI-TOF MS systems, polymerase chain reaction (PCR)-based and sequencing-based assays. The presented assays are based on various properties, like biochemical tests, specific DNA sequences, composition of cellular fatty acids, protein profiles and have specific limitations. SIGNIFICANCE AND IMPACT OF THE STUDY: The number of opportunistic infections caused by Corynebacteria is increasing due to increase in number of immunocompromised patients. New Corynebacterium species and new human infections, caused by this group of bacteria, has been described recently. However, identification of Corynebacteria is still a challenge despite application of sophisticated laboratory methods. In the study we present possibilities and limitations of various commercial systems for identification of Corynebacteria. PMID- 29573442 TI - Asbestos standards: Impact of currently uncounted chrysotile asbestos fibers on lifetime lung cancer risk. AB - BACKGROUND: Current regulations require that asbestos fibers are collected and examined using a light microscope. This method fails to enumerate fibers that are too short or thin to reliably count using a light microscope under normal conditions. METHODS: A cohort of 3054 workers employed at an asbestos textile plant was followed to ascertain causes of death. Exposure was almost entirely chrysotile. Fiber counts were quantified using light microscopy and electron microscopy. The g-formula was used to estimate impacts on lung cancer of policies defined in terms of fiber counts quantified using light and electron microscopy. RESULTS: Given exposure at the current standard, the estimated lung cancer risk was 7.33%, comparable to the risk expected under a standard of 1 fiber/mL counted using electron microscopy (7.30%). The lifetime risk of lung cancer under a standard of 0.1 fiber/mL counted by electron microscopy was estimated to be 7.10%. CONCLUSIONS: We identify policies defined in terms of electron microscopy based asbestos exposure metrics that yield comparable, or lower, lung cancer mortality than that expected under the current standard. PMID- 29573443 TI - Stevens-Johnson syndrome and toxic epidermal necrolysis-like cutaneous presentation of chikungunya fever: A case series. AB - Chikungunya fever is a benign, self-limiting, acute viral illness. An epidemic occurred in New Delhi, India, in August and September 2016. We observed many cases with atypical cutaneous features mimicking Stevens-Johnson syndrome and toxic epidermal necrolysis during this epidemic, especially in infants and children. Twenty-one children (13 [61.9%] boys, 8 [38%] girls) presenting with vesico-bullous and necrotic lesions were reviewed. Cutaneous presentation included vesicles and bullae with purpuric macules and necrosis, seen in 16 (76%) patients. Skin lesions resolved in 5-7 days, leaving behind hyperpigmentation in seven (33.3%) patients and hypopigmentation in three (14.2%). Minor oral erosions were observed in three (14.2%) patients, and palmoplantar erythema was seen in four (19.04%). It is essential for dermatologists to understand the Stevens Johnson syndrome and toxic epidermal necrolysis-like presentation of chikungunya and not to misinterpret it as true Stevens-Johnson syndrome and toxic epidermal necrolysis, which will lead to unnecessary intervention and management. PMID- 29573444 TI - Assessment of palliative care needs of patients/families living with cancer in a developing country. AB - PURPOSE: The study seeks to assess the care needs of oncology in-patients and clinic attendees or families in two tertiary health institutions. METHODS: This was a descriptive study which utilised a quantitative survey questionnaire of all cancer patients diagnosed between January 2014 and September 2016 (n = 547) with the return rate (n = 455) representing 82%. The questionnaire explored assessment of palliative care need. These instruments were used, because patients with cancer and their families are reluctant to talk about the disease. Using a questionnaire was therefore the best means of obtaining their full participation. The data were analysed using descriptive statistics to identify the highest need of patients with cancer patients. The study was approved by the two participating hospitals and the Human and Social Sciences Research Ethics of University of KwaZulu-Natal. FINDINGS: The study found that most common needs of patients were information on possibilities of treatment and side effects (92.8%), diagnosis (91.6%), testing (91.1%) and physical symptoms (90.9%). There were also other needs, such as psychological, spiritual and financial needs, related to factors causing distress to patients and their families following diagnosis of cancer. CONCLUSIONS: This article focused on needs as expressed by patients and families and offers a useful guide to develop a model for integration of palliative care activities. The findings reveal that patients who are undergoing follow-up care and cancer treatment or investigation are clearly concerned about receiving information on a range of cancer issues. We therefore conclude that patients are able to deal with the disease more effectively when hospitals set up a palliative care team or unit to carry out proper assessment of patients living with cancer. PMID- 29573445 TI - Emergence of African species of dermatophytes in tinea capitis: A 17-year experience in a Montreal pediatric hospital. AB - BACKGROUND/OBJECTIVES: An increase in dermatophyte infections caused by African species is reported in countries receiving African immigrants. Our goal was to determine the epidemiologic and clinical characteristics of tinea capitis in children infected with African species of dermatophytes in Montreal, Canada. METHODS: Demographic and clinical data from medical records of children infected with African species of dermatophytes were retrieved retrospectively (2000-2016) at Sainte-Justine University Hospital Center. RESULTS: In Montreal, the number of tinea capitis cases caused by African species of dermatophytes increased sixfold over 17 years. African immigrant children (84%), men and boys (61%), and preschoolers (2-5 years old) (51%) were the most frequently affected in our 315 cases. Family contamination was frequent (45%). Referring physicians prescribed systemic antifungal treatment in 39% of cases and pediatric dermatologist consultants in 90%. Treatment failure to oral terbinafine occurred in 39% of Microsporum audouinii infections. CONCLUSION: In Montreal, there was a significant increase in tinea capitis caused by African species of dermatophytes. Microsporum audouinii is highly transmissible and often resistant to oral terbinafine. Recognizing tinea capitis trends in a given environment will improve patient care. PMID- 29573446 TI - Scoliosis vertebral growth plate histomorphometry: Comparisons to controls, growth rates, and compressive stresses. AB - Scoliosis progression in skeletally immature patients depends on remaining growth. Relationships between vertebral growth plate histomorphometry, growth rates, and mechanical stresses have been reported in several animal studies. Hypertrophic zone heights and chondrocyte heights have been used to assess treatments that aim to modulate growth. The purpose of this study was to determine whether human vertebral physeal hypertrophic zone and cell heights differed between two groups: Severe scoliosis and autopsy controls. Severity was defined at time of surgical planning by curve magnitude and curve stiffness. Physeal samples were obtained from the convex side apex, and from the concave side when feasible. Histologic sections were prepared, and digital images were used to measure hypertrophic zone height, cell height, and cell width. Thirteen spinal deformity patients were included, mean curve magnitude 67 degrees (+/ 23). Etiologies were juvenile and adolescent idiopathic, congenital, neurofibromatosis, neuromuscular, and Marfan syndrome. Five age-matched autopsy specimens without scoliosis served as controls. Results were presented by etiology, then all convex scoliosis specimens were combined and compared to controls. Zone heights for scoliosis, convex side, and controls were 152 um (+/ 34) and 180 um (+/-42) (p = 0.21), cell heights 8.5 um (+/-1.1) and 12.8 um (+/ 1.2) (p < 0.0005), and cell widths 14.9 um (+/-1.5) and 15.0 um (+/-2.5), respectively. Human values were compared to published animal models and to a quantitative theory of a stress growth curve. This quantification of vertebral physeal structures in scoliosis may be expected to help assess theories of progression and potential treatments using growth modulation.

AB - Hypertrichosis is a condition in which hair is longer and denser than what is considered normal for an individual based on age, sex, ethnicity, and location on the body and can be classified based on its distribution (generalized vs localized), age of onset (congenital vs acquired), and type of hair (lanugo or vellus vs terminal). We describe a rare case of monozygotic female twins who presented for localized hypertrichosis of the intermammary cleft that developed during puberty. Endocrine examination was unremarkable. Discussion of various treatment modalities should be considered, because localized hypertrichosis may have a considerable psychosocial effect.

PMID- 29573449 TI - Monoclonal antibody 7D5 recognizes the R147 epitope on the gp91phox , phagocyte flavocytochrome b558 large subunit. AB - Human phagocyte flavocytochrome b558 (Cyt b), the catalytic center of nicotinamide adenine dinucleotide phosphate oxidase, consists of a heavily glycosylated large subunit (gp91phox ; Nox2) and a small subunit (p22phox ). Cyt b is a membrane-spanning complex enzyme. Chronic granulomatous disease (CGD) is predominantly caused by a mutation in the CYBB gene encoding gp91phox on the X chromosome. Because the phagocytes of patients with CGD are not able to generate the superoxide anion, these patients are susceptible to severe infections that can be fatal. It has been suggested that the extracellular region of gp91phox is necessary for and critical to forming the epitope of mAb 7D5 and that 7D5 provides a useful tool for rapid screening of X-linked CGD by FACS. To further elucidate the mAb 7D5 epitope on human gp91phox , chimeric DNA expressed human and mouse gp91phox recombinant protein were constructed. The fusion proteins were immunostained for mAb 7D5 and analyzed by FACS and western blot analysis. The 143 ELGDRQNES151 region was found to reside at the extracellular surface on human gp91phox and to be an important epitope for the interaction with mAb 7D5, as analyzed by FACS analysis. In particular, amino acid R147 is a unique epitope on the membrane-associated Cyt b for mAb 7D5. In conclusion, it is proposed that FACS analysis using mAb 7D5 is a valuable tool for early diagnosis of CGD.

AB - Subcutaneous granuloma annulare is a benign inflammatory disorder that primarily affects healthy children and manifests as a rapidly growing, painless, nonmobile mass, most commonly located in the leg. The current case highlights the sonographic appearance of subcutaneous granuloma annulare. Ultrasound color Doppler is a helpful noninvasive imaging test that may allow physicians to confirm the diagnosis of subcutaneous granuloma annulare and avoid unnecessary medical procedures. PMID- 29573451 TI - Data set for the reporting of intrahepatic cholangiocarcinoma, perihilar cholangiocarcinoma and hepatocellular carcinoma: recommendations from the International Collaboration on Cancer Reporting (ICCR). AB - Optimal patient management benefits from comprehensive and accurate pathology reports that contribute to cancer staging and prognostication. Proforma reports are used in many countries, but these vary in their structure and implementation. The International Collaboration on Cancer Reporting (ICCR) is an alliance formed by the Royal College of Pathologists of Australasia, the Royal College of Pathologists of the United Kingdom, the College of American Pathologists, the Canadian Partnership Against Cancer the European Society of Pathology and the American Society of Clinical Pathology (ASCP), with the aim of developing an evidence-based reporting data set for each cancer site. It is argued that this should reduce the global burden of cancer data set development and reduplication of effort by different international institutions that commission, publish and maintain standardised cancer reporting data sets. The resultant standardisation of cancer reporting will benefit not only those countries directly involved in the collaboration but also others not in a position to develop their own data sets. We describe the development of a cancer data set by the ICCR expert panel for the reporting of the main malignant liver tumours: intrahepatic cholangiocarcinoma, perihilar cholangiocarcinoma and hepatocellular carcinoma and present the 'required' and 'recommended' elements to be included in the report with an explanatory commentary. This data set incorporates definitions and classifications in the most recent World Health Organisation (WHO) publication on hepatic malignancies (4th edition) and the recently published tumour-node metastasis (TNM)8 staging system. Widespread adoption and implementation of this data set will enable consistent and accurate data collection, comparison of epidemiological and pathological parameters between different populations, facilitate research and ultimately result in better patient outcomes. PMID- 29573452 TI - In-hospital outcomes comparison of transfemoral vs transapical transcatheter aortic valve replacement in propensity-matched cohorts with severe aortic stenosis. AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the preferred option for high-risk patients with severe aortic stenosis. The preferred access for TAVR is transfemoral (TF). Alternatives include the transapical (TA), trans-subclavian (TS), and direct aortic (TAo) approaches. HYPOTHESIS: The TF approach is associated with lower in-hospital outcomes as well as shorter length of stay and lower cost of hospitalization. METHODS: The National Inpatient Sample database from 2012 through 2014 was used to obtain the TAVR study population. International Classification of Diseases, 9th Revision, Clinical Modification procedure codes were utilized to identify the 2 groups. In-hospital outcomes were compared in propensity-score-matched (1:3) cohorts, in which we took TA-TAVR as a control. RESULTS: A total of 8210 (weighted N = 41 050) patients were identified. Of these, 1622 (weighted N = 8110) patients underwent TA-TAVR and 6588 (weighted N = 32 940) patients underwent TF-TAVR. In-hospital mortality was lower with TF TAVR (4% vs 5.4%; P = 0.0355), along with a shorter length of stay (7.7 vs 9.7 days; P < 0.0001) and lower median hospitalization cost ($64 216 vs $74 735; P < 0.0001). Secondary outcomes of acute renal failure, transfusion, cardiogenic shock, and composite of all complications were lower with TF-TAVR. CONCLUSIONS: TF-TAVR is safer and associated with lower in-hospital outcomes compared with TA TAVR and should be the preferred approach. As TAVR is gaining popularity in intermediate- and low-risk patients, we must not lose sight of the serious mortality and secondary outcomes associated with TA-TAVR access.

AB - A new hybrid template was designed by combining the structural features of phosphodiesterase 4 (PDE4) inhibitors with several heterocyclic moieties which present an integral part in the skeleton of many apoptotic agents. Thirteen compounds of the synthesized hybrids displayed higher inhibitory activity against PDE4B than the reference drug, roflumilast. Further investigation indicated that compounds 13b and 20 arrested the cell cycle at the G2/M phase and the pre-G1 phase, and induced cell death by apoptosis of A549 cells in a caspase-dependent manner. PMID- 29573454 TI - Determination of the occlusal vertical dimension in edentulous patients using lateral cephalograms. AB - The determination of the occlusal vertical dimension (OVD) in edentulous patients is based on clinical assessment with high variability. This study tested the hypothesis: The average OVD in edentulous patients with conventional dentures is too low compared to orthodontic norms, when only clinical parameters are used for the determination of the OVD. Edentulous patients with conventional full dentures were enrolled. Clinical parameters were judged by two senior prosthodontists. Digital lateral cephalograms were taken and served to calculate the OVD according to the lower face height angle (ANS-Xi-D) taking tooth-independent facial growth patterns into account. The ANS-Xi-D angle was compared with reference values by applying one-sample mean comparison tests. Thirty-six participants (17 female, 19 male; mean age 65.3 +/- 10.6 years) were enrolled in this study. Clinically, the OVD of four dentures was judged too low, in one case too high, and in the other 31 cases as correct. The mean ANS-Xi-D angle was 48.28 degrees +/-4.86 and statistically not different to the norm value of 49 degrees +/-4 (n.s.). There was a tendency that the ANS-Xi-D angle was different between participants with different tooth-independent facial growth patterns (ANOVA, P = .0548). Predominantly, clinically sufficient prostheses show adequate ANS-Xi-D angles. Short-face type denture patients are often restored to comply with mesiofacial norms. The determination of the OVD based on lateral cephalography is not recommendable to be a standard diagnostic parameter.

AB - We compared biochemical, functional, and behavioral responses to the organophosphorus anticholinesterase chlorpyrifos oxon (CPO) in mice (Mus musculus, CD-1) and toads (Anaxyrus cognatus, Great Plains toad). Toads were substantially less sensitive to acute lethality of CPO based on the maximum tolerated (nonlethal) dose (toads, 77 mg/kg; mice, 5.9 mg/kg). Sublethal exposures led to classical signs of toxicity (increased involuntary movements, autonomic secretions) in mice but hypoactivity in toads. Motor performance in an inclined plane test was not affected by CPO in mice but was altered at the highest dosage in toads. Acetylcholinesterase (AChE), butyrylcholinesterase, monoacylglycerol lipase, and fatty acid amide hydrolase activities in brain were inhibited in mice but not in toads, and fatty acid amide hydrolase activity in the liver was inhibited in both species. Toad brain AChE was less sensitive to in vitro inhibition by CPO (50% inhibitory concentration [IC50; 20 min, 37 degrees C], 101 vs 7.8 nM; IC50 [20 min, 26 degrees C], 149 vs 6.2 nM), and studies of inhibitor kinetics indicated substantially lower anticholinesterase potency of CPO against the toad brain enzyme. Using an in vitro indirect inhibition assay, preincubation of CPO with toad brain homogenate was more effective than an equivalent mouse brain homogenate at reducing CPO potency. These data suggest that the relatively low sensitivity of toads to cholinergic toxicity is based on the low sensitivity of brain AChE, which in turn may be attributable to more effective target-site detoxification.

AB - Asymmetric hypertrophy of the labia minora is a variant of normal anatomy that has not been described in the pediatric dermatology literature. Although often asymptomatic, in some cases, it can cause functional, emotional, and psychological problems. We report the clinical characteristics and outcomes of four children who presented with unilateral labium minus hypertrophy. This case series aims to establish awareness of this condition among pediatric dermatologists and provide recommendations regarding management.

AB - Atopic dermatitis is a chronic, pruritic inflammatory disease that often disrupts sleep in severely affected children, but there are limited studies to guide clinical management of these sleep problems. Disease control is crucial in improving sleep, but additional sleep aids may sometimes be helpful in decreasing scratching during the night. This review discusses the benefits and limitations of potential therapeutic agents available to manage sleep disturbances in children with atopic dermatitis. PMID- 29573458 TI - Solitary pigmented lesions in oral mucosa in Latin American children: A case series. AB - BACKGROUND: A variety of local and systemic processes caused exogenous and endogenous pigmentation of the oral mucosa. Solitary melanotic pigmentation is rare, hence the scarce number of studies in children and adolescents. METHODS: Clinical and histopathologic features of 10 Latin American children with solitary pigmented lesions of the oral mucosa were reviewed. RESULTS: The area most affected was the gingiva, followed by the palate. All lesions were flat and <1 cm in diameter. A brown color was observed in oral melanocytic macules and nevi. The exogenously pigmented lesion was bluish gray. Histopathology showed that the biopsied lesions corresponded to melanotic macules, junctional nevus, blue nevus, and exogenous pigmentation. CONCLUSION: Solitary pigmented lesions on the oral mucosa of children, from melanin pigment or exogenous pigment, may have a similar clinical presentation, but melanotic lesions such as oral melanotic macules and nevi can be differentiated from one another only with histopathologic examination.

AB - AIMS: Previous evidence has demonstrated that participation in the Dose Adjustment for Normal Eating (DAFNE) education programme can reduce HbA1c and severe hypoglycaemia in people with Type 1 diabetes. In a number of studies, increased HbA1c variability has been associated with higher diabetic morbidity and mortality. No studies have examined the impact of structured education on HbA1c variability in Type 1 diabetes. METHODS: People with Type 1 diabetes who had attended DAFNE were identified for inclusion from the Scottish Care Information-Diabetes dataset. HbA1c median and variability, expressed as coefficient of variation (CV) before and after DAFNE was calculated. RESULTS: Some 1061 individuals participated in DAFNE education and 687 met the inclusion criteria. A significant median reduction in HbA1c [-3.5 mmol/mol (-0.3%)] was seen at 12 months with a significant reduction [-1.5 mmol/mol (-0.1%)] still seen at 60 months of follow-up. HbA1c variability as measured by CV was significantly lower during the post-DAFNE period: 0.08 (IQR 0.05-0.12) reduced to 0.07 (IQR 0.05-0.10); P = 0.002. CONCLUSION: The data confirm that DAFNE participation improves glycaemic control in Type 1 diabetes with benefits being sustained for 5 years. This study is the first to demonstrate reduced HbA1c variability after completion of structured education. This is new evidence of the beneficial impact of DAFNE on glycaemic profile. PMID- 29573460 TI - Subjective oral symptoms associated with self-rated oral health among Indigenous groups in Central-West Brazil. AB - OBJECTIVES: To determine whether subjective oral symptoms were associated with self-rated oral health after controlling for sociodemographic characteristics and dentition status in 4 different Indigenous peoples from Central-West Brazil. METHODS: A population-based cross-sectional study of oral health was conducted between 2012 and 2014. The randomly selected sample was stratified according to 4 ethnic groups (Kaiwoa, Kadiweu, Terena and Guarani) and 2 age groups (15-19 and 35-44 years). The outcome was poor self-rated oral health. Independent variables obtained by interviews were age, sex, ethnicity, schooling, family income, self reported toothache, difficulty chewing and difficulty speaking due to dental problems. Dentition status, oral morbidity and normative treatment needs were obtained through oral examinations. Unadjusted and adjusted prevalence ratios (PR) and respective 95% confidence intervals (CI) were estimated using Poisson regression modelling with robust variance estimation. RESULTS: Poor self-rated oral health was more common in the older age group and in Guarani peoples than their counterparts (PR = 1.06 [1.00-1.12]; PR = 1.09 [1.02-1.16], respectively). After adjusting for sociodemographic characteristics, fewer functional teeth (PR = 1.11 [1.02-1.20]), 2 or more untreated decayed teeth (PR = 1.15 [1.07-1.23]), normative need for extraction (PR = 1.15 [1.05-1.25]) and normative need for restoration of one or more surfaces (PR = 1.16 [1.05-1.27]) were positively associated with self-rated oral health. Toothache and difficulty speaking remained positively associated with the outcome after controlling for all previous variables (PR = 1.10 [1.05-1.18]; PR = 1.20 [1.09-1.32]). CONCLUSIONS: Oral symptoms such as toothache and difficulty speaking due to dental problems play an important role in oral health self-rating. Self-rated oral health is an appropriate indicator for use in diverse sociocultural contexts.

AB - BACKGROUND: Since the early 1990s, Iran has initiated structural and decentralization reforms in the hospital system. This policy led to the formation of a Board of Trustees (BOTs) for the governing of public educational hospitals and making important modifications in hospitals' financing. This study was conducted to identify the barriers in implementing this policy. METHODS: All the Iranian Medical Sciences Universities and hospitals involved in the policy implementation were included in this qualitative study. The data were analyzed by using content analysis. RESULTS: In total, 403 problems were divided into 9 classes including problems related to implementing regulation, financial problems in policy implementation, problems related to faculty members, ambiguity in executive regulation, problems related to the BOTs, authority level, hospital structure, the quality and quantity of hospital human resources, and fee for services. CONCLUSION: It appears that "implementing regulation" and "financial problems" embrace over 50% of the barriers. Apparently, the new approach to hospitals' autonomy has not achieved the desired goals. Considering the contextual factor, the evidence and identification of the clear role of various stakeholders should be essential determinants. Partial implementation of this policy without paying attention to the other aspects would end in failure. The results showed insufficient budget to be the most influential factor that posed a dilemma in implementing the BOTs' policy. However, BOTs in Iranian health system need to strive toward a higher level of performance that will improve effectiveness and efficiency now more than ever. PMID- 29573462 TI - University of Wisconsin vs normal saline solutions for preservation of blood vessels of brain dead donors: A histopathological study. AB - OBJECTIVE: To compare the cellular changes of harvested arteries which were preserved in normal saline (NS) and the standard and routinely used University of Wisconsin (UW) solution. METHODS: This experimental study was conducted on 20 brain dead patients. The femoral and iliac arteries were bilaterally removed and were placed in NS and UW solutions. The vascular change indices including endothelial detachment (ED), medial detachment (MD), and internal elastic membrane disruption (IEMD) were surveyed for each preserver in the first, 5th, 10th, and 21st day. RESULTS: The mean age of the included patients was 32.28 +/- 8.88 years, and there were 13 (65.0%) men and 7 (35.0%) women among the patients. The NS and UW preservation solutions were comparable regarding the indices of vascular changes at first, 5th, and 10th day of the study. Only in 21st day of the study, there was a significant difference between 2 group regarding MD changes (P = .049). CONCLUSION: The results of this in vitro study demonstrated that NS can be used as a worthy preserver for harvested vessels for up to 21 days, especially in resource-limited transplantation centers. PMID- 29573463 TI - Decomposing inequality in financial protection situation in Iran after implementing the health reform plan: What does the evidence show based on national survey of households' budget? AB - BACKGROUND: Lack of well-designed healthcare financing mechanisms and high level of out-of-pocket payments in Iran over the last decades led to implementing Health Transformation Plan, in 2014. This study aims to decompose inequality in financial protection of Iranian households after the implementation of the Health Transformation Plan. METHODS: The data of Statistical Center of Iran (SCI) Survey on Rural and Urban Households Income-Expenditure in 2015 to 2016 were used. The headcount ratio of catastrophic health expenditures was calculated. The corrected concentration index was estimated. The role of contributors on inequality in the exposure to catastrophic health expenditures among poor and nonpoor households was calculated using Farelie's model. RESULTS: The headcount ratio of the exposure to catastrophic health expenditures in urban and rural households was 2.5% (2.43% - 2.64%) and 3.6% (3.48% - 3.76%), respectively. The difference in households' income levels was the main contributor in explaining the inequality in facing catastrophic health expenditures between poor and nonpoor households. [Correction added on 02 June 2018, after first online publication: The "Results" section of the Abstract of the published article has been correctly updated on this version.] CONCLUSION: Even after implementing the HTP, the headcount ratios of catastrophic health expenditure are still considerable. The results show that income is the greatest determinant of inequality in facing catastrophic health expenditure and in urban households. PMID- 29573464 TI - Pseudopod-associated protein KIF20B promotes Gli1-induced epithelial-mesenchymal transition modulated by pseudopodial actin dynamic in human colorectal cancer. AB - Kinesin family member 20B (KIF20B) has been reported to have an oncogenic role in bladder and hepatocellular cancer cells, but its role in colorectal cancer (CRC) progression remains unclear. In this study, we assessed the mRNA and protein levels of KIF20B in CRC tissues using qRT-PCR and immunohistochemistry, respectively. KIF20B was overexpressed in CRC tissues and was associated with cancer invasion and metastasis. Mechanistically, KIF20B overexpression promoted the epithelial-mesenchymal transition (EMT) process mediated by glioma-associated oncogene 1 (Gli1) as well as CRC cell migration and invasion. Interestingly, KIF20B was localized in pseudopod protrusions of CRC cells and influenced the formation of cell protrusions, especially the EMT-related invadopodia. Moreover, intracellular actin dynamic participated in the modulation of the Gli1-mediated EMT and EMT-related cell pseudopod protrusion formation induced by KIF20B. We identified a role for KIF20B in CRC progression and revealed a correlation between KIF20B expression in CRC tissues and patient prognosis. The underlying mechanism was associated with the Gli1-mediated EMT and EMT-related cell protrusion formation modulated by intracellular actin dynamic. Thus, KIF20B may be a potential biomarker and promising treatment target for CRC. PMID- 29573465 TI - Low dose irradiation facilitates hepatocellular carcinoma genesis involving HULC. AB - Irradiation exposure positive correlates with tumor formation, such as breast cancer and lung cancer. However, whether low dose irradiation induces hepatocarcinogenesis and the underlying mechanism remain poorly defined. In the present study, we reported that low dose irradiation facilitated the proliferation of hepatocyte through up-regulating HULC in vitro and in vivo. Low dose irradiation exposure elevated HULC expression level in hepatocyte. Deletion of heightened HULC erased the cells growth accelerated following low dose irradiation exposure. CDKN1, the neighbor gene of HULC, was down-regulated by overexpression of HULC following low dose irradiation exposure via complementary base pairing, resulting in promoting cell cycle process. Thus, our findings provide new insights into the mechanism of low dose irradiation-induced hepatocarcinogenesis through HULC/CDKN1 signaling, and shed light on the potential risk of low dose irradiation for the development of hepatocellular carcinoma in pre-clinical settings.

AB - The two enantiomers of ethyl 3-hydroxybutyrate are important intermediates for the synthesis of a great variety of valuable chiral drugs. The preparation of chiral drug intermediates through kinetic resolution reactions catalyzed by esterases/lipases has been demonstrated to be an efficient and environmentally friendly method. We previously functionally characterized microbial esterase PHE21 and used PHE21 as a biocatalyst to generate optically pure ethyl (S)-3 hydroxybutyrate. Herein, we also functionally characterized one novel salt tolerant microbial esterase WDEst17 from the genome of Dactylosporangium aurantiacum subsp. Hamdenensis NRRL 18085. Esterase WDEst17 was further developed as an efficient biocatalyst to generate (R)-3-hydroxybutyrate, an important chiral drug intermediate, with the enantiomeric excess being 99% and the conversion rate being 65.05%, respectively, after process optimization. Notably, the enantio-selectivity of esterase WDEst17 was opposite than that of esterase PHE21. The identification of esterases WDEst17 and PHE21 through genome mining of microorganisms provides useful biocatalysts for the preparation of valuable chiral drug intermediates. PMID- 29573467 TI - Electrocardiographic changes before and after successful kidney transplantation and associations with cardiovascular and mortality outcomes. AB - INTRODUCTION: Electrocardiographic (ECG) changes before and after kidney transplantation are not well-defined. Our aim was to describe the evolution of ECG in patients on dialysis before and after successful kidney transplantation and to explore the association between ECG findings and major cardiovascular (CV) events and mortality after kidney transplantation. PATIENTS AND METHODS: Electrocardiographics were collected retrospectively 3 times: at entry to the transplantation waiting list, at transplantation, and 1 year after the transplantation from 212 kidney transplantation recipients. Altogether 19 ECG variables were analyzed. RESULTS: Left ventricular hypertrophy was present in 10.2% by the Cornell voltage-duration product criteria and 10.7% by the Sokolow Lyon voltage criteria before kidney transplantation. The presence of ST depression (OR 3.12, 95% CI 1.12 -8.7 and P = .03) at entry to the waiting list and Q wave at the time of transplantation (OR 3.28, 95% CI 1.06-10.10 and P = .04) were both independently associated with major CV events after the transplantation. In addition, the presence of Q wave at entry to the waiting list was a risk factor of premature death after the transplantation (OR 2.92, 95% CI 1.06-8.05 and P = .04). DISCUSSION: Careful analysis of the ECG before transplantation can be used to estimate cardiovascular events and mortality risk after kidney transplantation. PMID- 29573468 TI - Line-assisted complete closure for a large mucosal defect after colorectal endoscopic submucosal dissection decreased post-electrocoagulation syndrome. AB - BACKGROUND AND AIM: The incidence of post-endoscopic submucosal dissection (ESD) coagulation syndrome (PECS) can be decreased by closing mucosal defects. However, large mucosal defects after colorectal ESD cannot be closed endoscopically. We established line-assisted complete clip closure (LACC), a novel technique for large mucosal defects after colorectal ESD. We evaluated the prophylactic efficacy of LACC for preventing PECS. METHODS: Sixty-one consecutive patients on whom LACC after colorectal ESD was attempted from January 2016 to August 2016 were analyzed. After exclusion of patients with incomplete LACC and adverse events during ESD, 57 patients comprised the LACC group. In contrast, 495 patients who did not undergo closure of a mucosal defect comprised the control group. Propensity score matching was used to adjust for patients' backgrounds. Treatment outcomes were evaluated between the groups. RESULTS: Median resected specimen size in the LACC-attempted group was 35 mm (range, 20-72 mm), and LACC success rate was 95% (58/61). Median procedure time of LACC was 14 min. In the LACC group, incidence of PECS was only 2%, and no delayed bleeding or perforation occurred. Propensity score matching created 51 matched pairs. Adjusted comparisons between the LACC and control groups showed a lower incidence of PECS (0% vs 12%, respectively; P = 0.03) and shorter hospitalization (5 vs 6 days, respectively; P < 0.001) in the LACC group. CONCLUSION: This study suggests that LACC can effectively reduce the incidence of PECS, although further large-scale studies are warranted.

AB - Treatments to slow the progression of cognitive dysfunction to dementia and improve the quality of life of persons with Parkinson's disease (PD) are desperately needed. Because PD mild cognitive impairment is considered a transitional stage before dementia, it opens a window to timely intervention. This article critically reviews the strengths and challenges of pharmacologic and nonpharmacologic clinical therapeutic trials in PD mild cognitive impairment conducted during the past 5 years, including ongoing trials. Relatively few high quality trials have been conducted, and some important factors in designing future clinical trials are discussed. (c) 2018 International Parkinson and Movement Disorder Society. PMID- 29573470 TI - TCR deep sequencing of transgenic RAG-1-deficient mice reveals endogenous TCR recombination: a cause for caution. AB - The utility of T-cell receptor (TCR) transgenic mice in medical research has been considerable, with applications ranging from basic biology all the way to translational and clinical investigations. Crossing of TCR transgenic mice with either recombination-activating gene (RAG)-1 or RAG-2 knockouts is frequently used to generate mice with a monoclonal T-cell repertoire. However, low level productive TCR rearrangement has been reported in RAG-deficient mice expressing transgenic TCRs. Using deep sequencing, we set out to directly examine and quantify the presence of these endogenous TCRs. Our demonstration that functional nontransgenic TCRs are present in nonmanipulated mice has wide reaching ramifications worthy of critical consideration. PMID- 29573471 TI - Reward learning impairment and avoidance and rumination responses at the end of Engage therapy of late-life depression. AB - OBJECTIVES: This study examined the association between reward processing, as measured by performance on the probabilistic reversal learning (PRL) task and avoidance/rumination in depressed older adults treated with Engage, a psychotherapy that uses "reward exposure" to increase behavioral activation. METHODS: Thirty older adults with major depression received 9 weeks of Engage treatment. At baseline and treatment end, the 24-item Hamilton Depression Rating Scale (HAM-D) was used to assess depression severity and the Behavioral Activation for Depression Scale (BADS) to assess behavioral activation and avoidance/rumination. Participants completed the PRL task at baseline and at treatment end. The PRL requires participants to learn stimulus-reward contingencies through trial and error, and switch strategies when the contingencies unexpectedly change. RESULTS: At the end of Engage treatment, the severity of depression was lower (HAM-D: t(19) = -7.67, P < .001) and behavioral activation was higher (BADS: t(19) = 2.23, P = .02) compared to baseline. Response time following all switches (r(19) = -0.63, P = .003) and error switches (r(19) = -0.57, P = .01) at baseline was negatively associated with the BADS avoidance/rumination subscale score at the end of Engage treatment. CONCLUSIONS: Impaired reward learning, evidenced by slower response following all switches and error switches, contributes to avoidant, ruminative behavior at the end of Engage therapy even when depression improves. Understanding reward processing abnormalities of avoidance and rumination may improve the timing and targeting of interventions for these symptoms, whose persistence compromises quality of life and increases the risk of depression relapse.

PMID- 29573473 TI - FRAME Study: The Foundation Effect of Building Bone With 1 Year of Romosozumab Leads to Continued Lower Fracture Risk After Transition to Denosumab. AB - Romosozumab is a bone-forming agent with a dual effect of increasing bone formation and decreasing bone resorption. In FRActure study in postmenopausal woMen with ostEoporosis (FRAME), postmenopausal women with osteoporosis received romosozumab 210 mg s.c. or placebo once monthly for 12 months, followed by denosumab 60 mg s.c. once every 6 months in both groups for 12 months. One year of romosozumab increased spine and hip BMD by 13% and 7%, respectively, and reduced vertebral and clinical fractures with persistent fracture risk reduction upon transition to denosumab over 24 months. Here, we further characterize the BMD gains with romosozumab by quantifying the percentages of patients who responded at varying magnitudes; report the mean T-score changes from baseline over the 2-year study and contrast these results with the long-term BMD gains seen with denosumab during Fracture REduction Evaluation of Denosumab in Osteoporosis every 6 Months (FREEDOM) and its Extension studies; and assess fracture incidence rates in year 2, when all patients received denosumab. Among 7180 patients (n = 3591 placebo, n = 3589 romosozumab), most romosozumab-treated patients experienced >=3% gains in BMD from baseline at month 12 (spine, 96%; hip, 78%) compared with placebo (spine, 22%; hip, 16%). For romosozumab patients, mean absolute T-score increases at the spine and hip were 0.88 and 0.32, respectively, at 12 months (placebo: 0.03 and 0.01) and 1.11 and 0.45 at 24 months (placebo-to-denosumab: 0.38 and 0.17), with the 2-year gains approximating the effect of 7 years of continuous denosumab administration. Patients receiving romosozumab versus placebo in year 1 had significantly fewer vertebral fractures in year 2 (81% relative reduction; p < 0.001), with fewer fractures consistently observed across other fracture categories. The data support the clinical benefit of rebuilding the skeletal foundation with romosozumab before transitioning to antiresorptive therapy. (c) 2018 The Authors.

AB - Novel phenanthroline Schiff base fluorescent sensors L1, L2, and D1 were designed and synthesized. The sensing abilities of the compounds in the presence of metal cations (Li+ , Na+ , K+ , Ag+ , Mg2+ , Ba2+ , Ca2+ , Mn2+ , Pb2+ , Hg2+ , Ni2+ , Zn2+ , Cd2+ , Co2+ , Cu2+ , Cr3+ , Fe3+ , Fe2+ , Al3+ , and Eu3+ ) were studied by UV-vis and fluorescent spectroscopy. The compounds L1, L2, and D1 could act as Eu3+ ion turn-off fluorescent sensors based on ligand-to-metal binding mechanism in DMSO-H2 O solution (v/v = 1:1, 10 mM Tris, pH = 7.4). Additionally, the L1 Eu3+ and D1-Eu3+ complexes could be applied as turn-on enantioselective sensors sensing of malate anion isomers with color changes. Furthermore, biological experiments using living PC-12 cells demonstrated that L1 and D1 had excellent membrane permeability and could be used as effective fluorescent sensors for detecting Eu3+ and malate anion in living cells. PMID- 29573475 TI - Treatment of colon cancer with liver X receptor agonists induces immunogenic cell death. AB - Liver X receptor (LXR) agonists inhibit various types of tumor growth and have been applied to preclinical research. In colon cancer cells, LXR agonists induce pyroptotic cell death through the predominant cytoplasmic localisation of LXRbeta. In the present study, we determined whether tumor cell death induced by LXR agonists in colon cancer cells could elicit immunogenic cell death (ICD). LXR agonist-treated-colon cancer cells exhibited translocation of calreticulin (CRT) and release of HMGB1 and ATP into the medium. Expression levels of CRT and HMGB1 were also increased in T0901317-treated Balb/c mice. Furthermore, compared with control mice, mice vaccinated with T0901317-treated CT26 cells showed reduced tumor volumes and protection against a challenge with live tumor cells. Inhibition of CRT or HMGB1 expression in CT26 cells abolished this protection in Balb/c mice. In conclusion, the LXR agonist T0901317 induces ICD in colon cancer cells. CRT exposure and HMGB1 release play a critical role in the immunogenicity of this treatment. PMID- 29573476 TI - The multidisciplinary support in preventing alcohol relapse after liver transplantation: A single-center experience. AB - BACKGROUND AND AIM: Alcoholic liver disease (ALD) represents a frequent indication for liver transplantation (LT). Since 2004, we have adopted a program of multidisciplinary support(MS) to assist patients undergoing LT for ALD. We aimed at analyzing the relapse rate and the risk factors for relapse. The relapse rate was also compared with that of a historical group of patients who underwent transplantation. Their survival rate was also analyzed. PATIENTS AND METHODS: Consecutive patients with ALD transplanted from 2004 were included. The most important demographic, psychosocial, and clinical characteristics known to be associated with alcohol relapse were recorded. RESULTS: Sixty-nine patients underwent MS: 8.7% presented alcohol relapse. At multivariate analysis female gender (sHR 9.02, 95% CI 1.71-47.56, P = .009), alcohol withdrawal syndrome (sHR 5.89, 95% CI 1.42-24.46, P = .015) and a shorter time of MS program before LT (sHR 0.928 per month, 95% CI 0.870-0.988, P = .021) were identified as independent risk factors for relapse. The rate of alcohol relapse was significantly lower than that of the historical group who did not undergo MS (sHR 0.21, 95% CI: 0.06-0.68; P = .009). CONCLUSION: This study shows that a MS program may contribute to alcohol relapse prevention after LT in ALD patients. However, the relevance of this support needs to be confirmed by clinical trials.

PMID- 29573480 TI - The role of phototherapy in the surgical treatment of vitiligo: a systematic review. AB - Vitiligo is frequently treated with the combination of phototherapy and melanocyte transplantation. However, the additional benefit of phototherapy is unclear. Moreover, the optimal type and regimen of phototherapy are unknown. The objective of this systematic review was to identify whether phototherapy improves the outcome of melanocyte transplantation in vitiligo. We searched and screened for eligible studies in the databases of MEDLINE, EMBASE and CENTRAL. We included all clinical studies investigating melanocyte transplantation combined with phototherapy. After screening and selection of abstracts and full-texts, we found 39 eligible clinical studies with 1624 patients. The eligible studies investigated several phototherapy modalities, such as NBUVB (n = 9), PUVA (n = 19), UVA (n = 1), MEL (n = 4) and active sunlight exposure (n = 9). Four studies directly compared phototherapy versus no phototherapy and two studies confirmed the benefit of phototherapy for melanocyte transplantation. We found no significant differences in repigmentation in studies directly comparing phototherapy modalities. The overall quality of the studies was moderate to poor and high heterogeneity between studies was found. We found limited evidence that phototherapy improves the outcome of melanocyte transplantation in vitiligo. There is insufficient evidence to recommend a specific type or regimen of phototherapy. More studies should be performed investigating the additional benefit of different phototherapies and the preferred moment of phototherapy. PMID- 29573481 TI - Safety profile during initiation of propranolol for treatment of infantile haemangiomas in an ambulatory day-care hospitalization setting. AB - BACKGROUND: Propranolol is the mainstay of treatment for infantile haemangioma. Despite its good safety profile, it is not risk-free. Guidelines for propranolol initiation and monitoring have been suggested, but protocols vary among practitioners. OBJECTIVE: This study sought to assess the prevalence of adverse events and clinically significant fluctuations in haemodynamic parameters in children with infantile haemangioma during initiation of treatment with propranolol in a day-hospitalization setting. METHODS: Children with infantile haemangioma treated with propranolol in a day-hospitalization department of a tertiary paediatric medical centre in 2008-2014 were identified retrospectively. The pretreatment evaluation included clinical examination by a paediatric dermatologist and electrocardiography, echocardiography and clinical examination by a paediatric cardiologist. The propranolol dosage was escalated from 0.5 mg/kg/day to 2 mg/kg/day, divided into three doses/day, over 3 days. Heart rate, blood pressure and blood glucose level were measured before treatment onset and 60 min after the first two doses each day. The third dose was given at home. RESULTS: The cohort included 220 children aged 1 month to 5 years. No severe treatment-related adverse events were documented; 27 patients had minor side effects. There was a significant decrease in heart rate each day after the first two doses (P < 0.001), and in systolic blood pressure, on day 2 (1 mg/kg/day) after the first dose (P = 0.01). Blood glucose level remained stable. The haemodynamic changes were clinically asymptomatic and did not require intervention. CONCLUSIONS: Propranolol treatment (2 mg/kg/day in three doses) for infantile haemangioma is well tolerated and safe and may be administered and monitored in an ambulatory setting.

AB - INTRODUCTION: Cell membrane chromatography (CMC), as a highly selective type of affinity chromatography, has been demonstrated as an effective method to screen bioactive components acting on specific receptor from a complicated biological system. OBJECTIVE: To review the recent research progress and the technical applications of these analytical methods using CMC combined with gas chromatography-mass spectrometry, (GC/MS) and liquid chromatography-mass spectrometry (LC/MS). METHODOLOGY: In this review, we briefly introduce the CMC offline GC/MS, CMC online GC/MS, CMC offline LC/MS, and CMC online LC/MS system. And the practical application of these technologies is also enumerated. Then the future of these technologies and research methods were discussed. RESULTS: Many bioactive components interacting with specific receptors have been screened and identified in traditional Chinese medicines. CONCLUSION: CMC technique has been combined with GC/MS and HPLC/MS and these combined systems have been successfully used to screen bioactive components acting on specific receptors from a complicated biological system.

AB - BACKGROUND: Acne is a common chronic skin disease with a multifactorial aetiology and pathogenesis. Recently, circular RNAs (circRNAs) have been identified as a key factor in regulating gene expression through circRNA-miRNA-mRNA networks in many biological processes and human diseases. However, the circRNAs expression in patients with acne is still unknown. OBJECTIVE: To investigate circRNA expression profile in severe acne. METHODS: The expression profile of circRNAs in three paired lesional skin and adjacent non-lesional skin in severe acne was detected by high-throughput RNA sequencing technology and bioinformatics analysis. The candidate circRNAs were validated by PCR, Sanger sequencing and qRT-PCR in the separate group (n = 4). The circRNA-miRNA-mRNA interaction networks were predicted. RESULTS: A total of 538 circRNAs including 271 up- and 267 downregulated circRNAs were differentially expressed in lesional skin compared with adjacent non-lesional skin in severe acne. Gene Ontology and KEGG pathway enrichment analyses revealed that the aberrantly expressed circRNAs were primarily involved in inflammatory, metabolism and immune responses. Five candidate circRNAs (circRNA_0084927, circRNA_0001073, circRNA_0005941, circRNA_0086376 and circRNA_0018168) were validated to have significant decrease in severe acne by PCR, Sanger sequencing and qRT-PCR, in agreement with the results from RNA-Seq data analysis. The five identified circRNAs were predicted to interact with 213 miRNAs and regulated target gene expression. CONCLUSION: This study firstly showed that circRNAs were differentially expressed in severe acne and suggested that circRNAs could be used as a potential biomarker for the drug targets of acne.

AB - Bulk heterojunction (BHJ) solar cells might one day play a vital role in realizing low-cost and environmentally benign photovoltaic devices. In this work, a BHJ solar cell was designed, based on a hexadeca-substituted phthalocyanine (FcPc) with ferrocenyl linked to the phthalocyanine ring. Next, we sought to obtain more quantitative information about the usability of this newly synthesized compound as a donor material in BHJ solar cells. Thus, BHJs with the structure of indium tin oxide/poly(3,4 ethylenedioxythiophene):poly(styrenesulfonate)/FcPc:[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blend/LiF/Al were fabricated and characterized. The effect of blend ratio (0.5-2.0) on the BHJ solar cell parameters was also investigated. Interesting results were obtained in FcPc and the PCBM blend-based BHJ solar cell under optimized conditions. Our results presented here demonstrate that BHJ devices employing FcPc as a donor has great potential for the development of highly efficient non-poly(3-hexylthiophen-2,5-diyl) photovoltaic devices. PMID- 29573485 TI - High-Speed 3D Printing of Millimeter-Size Customized Aspheric Imaging Lenses with Sub 7 nm Surface Roughness. AB - Advancements in three-dimensional (3D) printing technology have the potential to transform the manufacture of customized optical elements, which today relies heavily on time-consuming and costly polishing and grinding processes. However the inherent speed-accuracy trade-off seriously constrains the practical applications of 3D-printing technology in the optical realm. In addressing this issue, here, a new method featuring a significantly faster fabrication speed, at 24.54 mm3 h-1 , without compromising the fabrication accuracy required to 3D print customized optical components is reported. A high-speed 3D-printing process with subvoxel-scale precision (sub 5 um) and deep subwavelength (sub 7 nm) surface roughness by employing the projection micro-stereolithography process and the synergistic effects from grayscale photopolymerization and the meniscus equilibrium post-curing methods is demonstrated. Fabricating a customized aspheric lens 5 mm in height and 3 mm in diameter is accomplished in four hours. The 3D-printed singlet aspheric lens demonstrates a maximal imaging resolution of 373.2 lp mm-1 with low field distortion less than 0.13% across a 2 mm field of view. This lens is attached onto a cell phone camera and the colorful fine details of a sunset moth's wing and the spot on a weevil's elytra are captured. This work demonstrates the potential of this method to rapidly prototype optical components or systems based on 3D printing. PMID- 29573486 TI - The low-molecular-mass, penicillin-binding proteins DacB and DacC combine to modify peptidoglycan cross-linking and allow stable Type IV pilus expression in Neisseria gonorrhoeae. AB - Neisseria gonorrhoeae is the causative agent of the sexually transmitted infection gonorrhea and is adapted to survive in humans, its only host. The N. gonorrhoeae cell wall is critical for maintaining envelope integrity, resisting immune cell killing and production of cytotoxic peptidoglycan (PG) fragments. Deletion of the N. gonorrhoeae strain FA1090 genes encoding two predicted low molecular-mass, penicillin-binding proteins (LMM PBPs), DacB and DacC, substantially altered the PG cross-linking. Loss of the DacB peptidase resulted in global alterations to the PG composition, while loss of the DacC protein affected a much narrower subset of PG peptide components. A double DeltadacB/DeltadacC mutant resembled the DeltadacB single mutant, but had an even greater level of cross-linked PG. While single DeltadacB or DeltadacC mutants did not show any major phenotypes, the DeltadacB/DeltadacC mutant displayed an altered cellular morphology, decreased resistance to antibiotics and increased sensitivity to detergent-mediated death. Loss of the two proteins also drastically reduced the number of Type IV pili (Tfp), a critical virulence factor. The decreased piliation reduced transformation efficiency and correlated with increased growth rate. While these two LMM PBPs differentially alter the PG composition, their overlapping effects are essential to proper envelope function and expression of factors critical for pathogenesis.

AB - In an attempt to prepare new Fe catalysts for the dehydrocoupling of amine boranes and to provide mechanistic insight, the paramagnetic FeII dimeric complex [Cp'FeI]2 (1) (Cp'=eta5 -((1,2,4-tBu)3 C5 H2 )) was used as a precursor to a series of cyclopentadienyl FeII and FeIII mononuclear species. The complexes prepared were [Cp'Fe(eta6 -Tol)][Cp'FeI2 ] (2) (Tol=C6 H5 Me), [Cp'Fe(eta6 Tol)][BArF4 ] (3) (BArF4 =[B(C6 H3 (m-CF3 )2 )4 ]- ), [N(nBu)4 ][Cp'FeI2 ] (4), Cp'FeI2 (5), and [Cp'Fe(MeCN)3 ][BArF4 ] (6). The electronic structure of the [Cp'FeI2 ]- anion in 2 and 4 was investigated by SQUID magnetometry, EPR spectroscopy and ab initio Complete Active Space Self Consistent Field-Spin Orbit (CASSCF-SO) calculations, and the studies revealed a strongly anisotropic S=2 ground state. Complexes 1-6 were investigated as catalysts for the dehydrocoupling of Me2 NH?BH3 (I) in THF at 20 degrees C to yield the cyclodiborazane product [Me2 N-BH2 ]2 (IV). Complexes 1-4 and 6 were active dehydrocoupling catalysts towards I (5 mol % loading), however 5 was inactive, and ultra-violet (UV) irradiation was required for the reaction mediated by 3. Complex 6 was found to be the most active precatalyst, reaching 80 % conversion to IV after 19 h at 22 degrees C. Dehydrocoupling of I by 1-4 proceeded via formation of the aminoborane Me2 N=BH2 (II) as the major intermediate, whereas for 6 the linear diborazane Me2 NH-BH2 -NMe2 -BH3 (III) could be detected, together with trace amounts of II. Reactions of 1 and 6 with Me3 N?BH3 were investigated in an attempt to identify Fe-based intermediates in the catalytic reactions. The sigma-complex [Cp'Fe(MeCN)(kappa2 -H2 BH?NMe2 H][BArF4 ] was proposed to initially form in dehydrocoupling reactions involving 6 based on ESI MS (ESI=Electrospray Ionisation Mass Spectroscopy) and NMR spectroscopic evidence. The latter also suggests that these complexes function as precursors to iron hydrides which may be the true catalytic species. PMID- 29573488 TI - Synthesis of Benzofuranones via Malonates Desymmetrization: Yield Increase by the Portion-wise Addition of Quinones. AB - The organocatalyzed addition of several malonates to 1,4-benzoquinones affords benzofuranones bearing a quaternary stereocenter with good enantioselectivity. This reaction is an intramolecular desymmetrization since it proceeds through the formation of an arylated achiral malonate that cyclizes to give the reaction product. The addition rate of the quinone dramatically affects the reaction yield which was originally low. The yield was considerably increased, in some cases, from less than 20 % to over 95 %, by adding the quinone in portions rather than at once, keeping similar enantioselectivity. A possible rationalization for the preferential formation of the indicated enantiomer has been investigated by DFT calculations.

AB - A 29-year old gravida 2, para 1 patient presented at 22+3 weeks' of gestation without abnormalities detected on the first ultrasound examination. At 24+0 weeks' gestation however, a tumor of 3x2cm potentially originating from the vagina was seen. The tumor's inner structure changed over time, initially presenting homogeneous and from 28 weeks' gestation onward inhomogeneous with hypoechogenic and hyperechogenic parts (Figure 1a,c). PMID- 29573491 TI - Generalized pustular psoriasis: a review and update on treatment. AB - Generalized pustular psoriasis (GPP) is a subtype of pustular psoriasis characterized by painful and occasionally disfiguring cutaneous manifestations with sepsis-like systemic symptoms. Affecting any age and race, GPP can occur with other forms of psoriasis or by itself. Stimuli for flares include medications, infections and environmental triggers. The interleukin family and caspase recruitment domain family have been implicated in its pathogenesis. Other forms of pustular psoriasis include impetigo herpetiformis, palmoplantar pustular psoriasis, annular pustular psoriasis and acrodermatitis continua of Hallopeau. Treatment is not well established, but includes the use of retinoids, methotrexate, cyclosporine, corticosteroids, TNF-alpha inhibitors, topical therapy and phototherapy. The use of TNF-alpha inhibitors may result in the formation of antidrug antibodies and should be administered with methotrexate. PMID- 29573490 TI - Extracellular matrix internalization links nutrient signalling to invasive migration. AB - Integrins are the key mediators of cell-extracellular matrix (ECM) interaction, linking the ECM to the actin cytoskeleton. Besides localizing at the cell surface, they can be internalized and transported back to the plasma membrane (recycled) or delivered to the late endosomes/lysosomes for degradation. We and others have shown that integrin can be endocytosed together with their ECM ligands. In this short review, I will highlight how extracellular protein (including ECM) endocytosis impinges on the activation of the mechanistic target of rapamycin (mTOR) pathway, a master regulator of cell metabolism and growth. This supports the intriguing hypothesis that ECM components may be considered as nutrient sources, primarily under soluble nutrient-depleted conditions.

AB - Within the framework of the COST program, ECOSTBio is a European network of both experimental and theoretical researchers that tackle a diversity of chemical problems in which electronic spin is a key factor.

PMID- 29573493 TI - Magnetic Interactions through a Nonconjugated Framework Observed in Back-to-Back Connected Triazinyl-Nitroxyl Biradical Derivatives. AB - Three hetero-biradical derivatives, with the structure of a back-to-back connected benzotriazinyl and tetramethyl or tetraethylisoindoline N-oxyl sharing a common benzo ring, 3-tert-butyl-1-phenyl-1,4,6,8-tetrahydro-6,6,8,8-tetramethyl pyrrolo[4,5-g]-1,2,4-benzotriazin-4-yl-7-oxyl (1-tBu), 1,3-diphenyl-1,4,6,8 tetrahydro-6,6,8,8-tetramethyl-pyrrolo[4,5-g]-1,2,4-benzotriazin-4-yl-7-oxyl (1 Ph), and 3-tert-butyl-1-phenyl-1,4,6,8-tetrahydro-6,6,8,8-tetraethyl-pyrrolo[4,5 g]-1,2,4-benzotriazin-4-yl-7-oxyl (2-tBu), were synthesized and characterized by single-crystal X-ray analyses, variable-temperature magnetic susceptibility studies, and DFT calculations. Temperature dependences of the magnetic susceptibilities of 1-tBu, 1-Ph, and 2-tBu exhibit broad maxima at 70, 71, and 43 K, respectively. Although these radical derivatives form a columnar or chained assembly in the solid state, magnetic measurements of diluted samples in the polymer matrices and computational results imply that the magnetic properties of the polycrystalline sample can be explained by a two-spin system with an intramolecular antiferromagnetic interaction. The magnetic behavior can be reproduced by using the Bleaney-Bowers model, with 2J=-80.0 cm-1 for 1-tBu, 2J= 77.1 cm-1 for 1-Ph, and 2J=-48.9 cm-1 for 2-tBu. The moderately strong intramolecular antiferromagnetic interactions can be interpreted by a through bond interaction through the nonconjugated framework and/or through-space interactions based on molecular orbital theory. The strong distance dependency between the N-O spin site and vinylic carbon atoms indicates that the orbital interaction plays an important role in the intramolecular magnetic interaction. The reduced magnetic interaction in 2-tBu relative to those of 1-tBu and 1-Ph can be attributed to restricted rotation of the tetraethyl group. PMID- 29573494 TI - Limitations of Steric Bulk: Towards Phospha-germynes and Phospha-stannynes. AB - The use of bulky aryl(silyl)amides (R) as substituents for the stabilisation of phospha-germynes and phospha-stannynes (R-Ge=P and R-Sn=P, respectively) is described. Such species can be transiently generated by photolysis of the phosphaketene precursors (RE(PCO); E=Ge, Sn). Utilisation of bulky amides R1 and R2 (R1 =Ar**NSi(OtBu)3 , where Ar**=2,6-bis[bis(4-tert-butylphenyl)methyl]-4 methylphenyl; R2 =Ar***NSi(iPr)3 , where Ar***=2,6-bis[bis(3,5-di-tert butylphenyl)methyl]-4-methylphenyl) facilitates the formation of diphosphene-type dimers, [(RGe)P]2 and [(RSn)P]2 . In an effort to circumvent dimerisation, the bulkier R3 substituent (R3 =Ar***NSi(4-tert-butylphenyl)3 ) was employed in an analogous series of experiments. This affords cyclic germylenes and stannylenes due to insertion of the terminal phosphide into Si-C bonds of the R3 substituent, which in case of the stannylene could act as a trap for another R3 -Sn=P moiety. All attempts to isolate terminal phosphide species were unsuccessful due to the reactivity of such compounds towards the organic periphery of the bulky amides, highlighting the limitations of highly sterically demanding functionalities. PMID- 29573495 TI - Efficient in planta gene targeting in Arabidopsis using egg cell-specific expression of the Cas9 nuclease of Staphylococcus aureus. AB - Gene targeting (GT), the programmed change of genomic sequences by homologous recombination (HR), is still a major challenge in plants. We previously developed an in planta GT strategy by simultaneously releasing from the genome a dsDNA donor molecule and creating a double-stranded break (DSB) at a specific site within the targeted gene. Using Cas9 form Streptococcus pyogenes (SpCas9) under the control of a ubiquitin gene promoter, we obtained seeds harbouring GT events, although at a low frequency. In the present research we tested different developmentally controlled promotors and different kinds of DNA lesions for their ability to enhance GT of the acetolactate synthase (ALS) gene of Arabidopsis. For this purpose, we used Staphylococcus aureus Cas9 (SaCas9) nuclease and the SpCas9 nickase in various combinations. Thus, we analysed the effect of single-stranded break (SSB) activation of a targeted gene and/or the HR donor region. Moreover, we tested whether DSBs with 5' or 3' overhangs can improve in planta GT. Interestingly, the use of the SaCas9 nuclease controlled by an egg cell-specific promoter was the most efficient: depending on the line, in the very best case 6% of all seeds carried GT events. In a third of all lines, the targeting occurred around the 1% range of the tested seeds. Molecular analysis revealed that in about half of the cases perfect HR of both DSB ends occurred. Thus, using the improved technology, it should now be feasible to introduce any directed change into the Arabidopsis genome at will. PMID- 29573496 TI - Molecular diversity and landscape genomics of the crop wild relative Triticum urartu across the Fertile Crescent. AB - Modern plant breeding can benefit from the allelic variation that exists in natural populations of crop wild relatives that evolved under natural selection in varying pedoclimatic conditions. In this study, next-generation sequencing was used to generate 1.3 million genome-wide single nucleotide polymorphisms (SNPs) on ex situ collections of Triticum urartu L., the wild donor of the Au subgenome of modern wheat. A set of 75 511 high-quality SNPs were retained to describe 298 T. urartu accessions collected throughout the Fertile Crescent. Triticum urartu showed a complex pattern of genetic diversity, with two main genetic groups distributed sequentially from west to east. The incorporation of geographical information on sampling points showed that genetic diversity was correlated to the geographical distance (R2 = 0.19) separating samples from Jordan and Lebanon, from Syria and southern Turkey, and from eastern Turkey, Iran and Iraq. The wild emmer genome was used to derive the physical positions of SNPs on the seven chromosomes of the Au subgenome, allowing us to describe a relatively slow decay of linkage disequilibrium in the collection. Outlier loci were described on the basis of the geographic distribution of the T. urartu accessions, identifying a hotspot of directional selection on chromosome 4A. Bioclimatic variation was derived from grid data and related to allelic variation using a genome-wide association approach, identifying several marker-environment associations (MEAs). Fifty-seven MEAs were associated with altitude and temperature measures while 358 were associated with rainfall measures. The most significant MEAs and outlier loci were used to identify genomic loci with adaptive potential (some already reported in wheat), including dormancy and frost resistance loci. We advocate the application of genomics and landscape genomics on ex situ collections of crop wild relatives to efficiently identify promising alleles and genetic materials for incorporation into modern crop breeding. PMID- 29573497 TI - Inverse association for diagnosis of Alzheimer's disease subsequent to both melanoma and non-melanoma skin cancers in a large, urban, single-centre, Midwestern US patient population. AB - BACKGROUND: Although literature demonstrates a decreased risk of Alzheimer's disease (AD) in individuals with various cancers, including squamous cell cancers (SCC) and basal cell cancers (BCC) comprising non-melanoma skin cancers (NMSC), there is a paucity of literature to substantiate an association between malignant melanoma (MM) and AD. OBJECTIVE: The aim of this study was to determine whether an association exists between MM and AD as well as for NMSC and AD. METHODS: A large urban, Midwestern, US, single-centre, medical record (EMR) data repository was searched between January 2001 and December 2015, to identify all patients at age >=60 and <89 years with a clinic follow-up of at least 1 year and no diagnosis for AD, MM or NMSC at the time of the study entry. Data collected included age, gender, race and duration of follow-up. MM and NMSC were detected by ICD-9 codes and ICD-10 codes. Incident diagnosis of AD was also detected by ICD-9 and ICD-10 codes. Logistic regression analysis was utilized to obtain crude and adjusted odds ratios (ORs). RESULTS: Data for a total of 82 925 patients with known race and gender and were detected. After adjusting for confounding factors (race, gender, age, cerebrovascular disease, peripheral vascular disease and diabetes), there was a significant decreased risk of subsequent AD in patients with MM (OR: 0.39; 95% CI: 0.16-0.96; P = 0.042) as well as in patients with BCC (OR: 0.18; 95% CI: 0.08-0.45; P < 0.0001) and for patients with SCC (OR: 0.08; 95% CI: 0.01-0.56; P = 0.013). CONCLUSION: These findings add to the growing body of evidence for a decreased risk of AD in patients with various cancers and highlight the need for ongoing research to elucidate both neurologic and biologic mechanisms that may underlie this apparent inverse association. PMID- 29573498 TI - Correlation between fetoplacental Dopplers and cardiac function in term fetuses. AB - OBJECTIVE: Redistribution of cardiac output is responsible for the "brain sparing" effect seen during periods of fetal stress. Our aim was to prospectively investigate the correlation between feto-placental Dopplers and cardiac function. METHODS: This prospective, observational study included normotensive women with appropriately grown, non-anomalous, singleton pregnancies. Participants underwent fortnightly ultrasounds from 36 weeks' gestation and intrapartum and neonatal outcomes were recorded. The correlation between fetoplacental Dopplers and various indices of cardiac function were evaluated. RESULTS: The final cohort included 273 women. The left ventricular cardiac output (LVCO), left to right ventricular cardiac output ratio (LVCO/RVCO) and global left ventricular strain were positively correlated with the cerebro-placental ratio (CPR) (p<0.001 and rho=0.29), (p<0.001, r=0.41) and (p<0.01 and rho=0.17) respectively. The CPR was inversely correlated with the left ventricular myocardial performance index (LVMPI) (p<0.01, rho=-0.18) and the RVCO, (p<0.001, rho=-0.28). The LVCO and global left ventricular strain were positively correlated with umbilical venous flow (p=0.04 and rho=0.18) and (p<0.001 and rho=0.25) respectively. There was no or minimal correlation between either the mean Uterine artery PulsatiIity Index or Umbilical artery PulsatiIity Index with any cardiac indices. CONCLUSION: The fetal CPR, middle cerebral artery pulsatility index and umbilical venous flow are positively correlated with LVCO, LVCO/RVCO and global left ventricular strain in term low risk women. PMID- 29573499 TI - Misorientation-Angle-Dependent Phase Transformation in van der Waals Multilayers via Electron-Beam Irradiation. AB - Misorientation-angle dependence on layer thickness is an intriguing feature of van der Waals materials, which causes stark optical gain and electrical transport modulation. However, the influence of misorientation angle on phase transformation is not determined yet. Herein, this phenomenon in a MoS2 multilayer via in situ electron-beam irradiation is reported. An AA'-stacked MoS2 bilayer undergoes structural transformation from the 2H semiconducting phase to the 1T' metallic phase, similar to a MoS2 monolayer, which is confirmed via in situ transmission electron microscopy. Moreover, non-AA' stacking, which has no local AA' stacking order in the Moire pattern, does not reveal such a phase transformation. While a collective sliding motion of chalcogen atoms easily occurs during the transformation in AA' stacking, in non-AA' stacking it is suppressed by the weak van der Waals strength and by the chalcogen atoms interlocked at different orientations, which disfavor their kinetics by the increased entropy of mixing. PMID- 29573501 TI - First-trimester and combined first- and second-trimester prediction of small-for gestational age and late fetal growth restriction. AB - OBJECTIVE: To develop a first-trimester or combined first- and second-trimester screening algorithm for the prediction of small-for-gestational age (SGA) and late fetal growth restriction (FGR). METHODS: This was a retrospective study of women with singleton pregnancy, who underwent routine first-, second- and third trimester ultrasound assessment. Late FGR was defined, at >= 32 weeks' gestation in the absence of congenital anomalies, as either (i) estimated fetal weight (EFW) or birth weight (BW) < 3rd centile, or (ii) EFW < 10th centile and either uterine artery mean pulsatility index (UtA-PI) > 95th centile or cerebroplacental ratio (CPR) < 5th centile. Neonates with BW < 10th centile, regardless of prenatal parameters, were defined as SGA. The predictive effectiveness of maternal and first- and second-trimester factors was tested using logistic regression and receiver-operating characteristics curve analyses. RESULTS: A total of 3520 fetuses were included (late FGR, n = 109 (3.1%); SGA, n = 292 (8.3%)). Of the late FGR cases, 56 (1.6%) fulfilled the antenatal criteria (EFW < 3rd centile or EFW < 10th centile plus abnormal UtA-PI or CPR) and were defined as prenatally detected late FGR. A first-trimester screening model (comprising conception method, smoking status, maternal height, pregnancy-associated plasma protein-A (PAPP-A) and UtA-PI) could predict 50.0% of the prenatally diagnosed and 36.7% of the overall late FGR fetuses for a 10% false-positive rate (FPR). A model combining first- and second-trimester screening parameters (conception method, smoking status, PAPP-A, second- trimester EFW, head circumference/abdominal circumference ratio and UtA-PI) could predict 78.6% of the prenatally detected, and 59.6% of the overall late FGR fetuses, for a 10% FPR (area under the curve 0.901 (95% CI, 0.856-0.947) and 0.855 (95% CI, 0.818 0.891), respectively). The prediction of SGA was suboptimal for both first trimester and combined screening. CONCLUSIONS: A simple model combining maternal and first- and second-trimester predictors can detect 60% of fetuses that will develop late FGR, and 79% of those fetuses that will be classified prenatally as late FGR, for a 10% FPR.

PMID- 29573500 TI - Effectiveness of palliative care interventions offering social support to people with life-limiting illness-A systematic review. AB - Individuals managing the challenges of life-limiting illness require adequate social support to maintain quality of life. Qualitative research reports that patients value highly the social support obtained in palliative care interventions such as day care and group therapies. This systematic review aims to summarise existing quantitative evidence on palliative care interventions that facilitate social support. Research literature was systematically searched using electronic databases and key journals. Searches returned a total of 6,247 unique titles of which sixteen were eligible for inclusion. Interventions include group therapies, group practical interventions and palliative day care. Outcome measures and study designs were heterogeneous. Only one study used a validated outcome measure of social support. Benefits were influenced by participant characteristics such as baseline distress. Partial economic evaluation was attempted by two studies. Methodological challenges include attrition and use of outcome measures that were insensitive to change. Statistically significant results were reported in psychological and physical domains. Evidence is limited due to methodological issues and a scarcity of quantitative research, particularly regarding long-term benefits and cost-effectiveness. Interventions may be more beneficial to some groups than others. PMID- 29573502 TI - Strengths promoting the recovery process in older adults with depression. AB - AIMS AND OBJECTIVES: To clarify strengths for promoting the recovery process among older adults with depression in Japan. BACKGROUND: With the ageing of the global population, care and treatment of older adults with depression has been attracting increased attention around the world. It has become clear that the inner strength is inversely related to depression in older adults and that the use of inner strength is becoming a key concept in the context of caring for older adults with depression. DESIGN: Qualitative descriptive design. METHODS: Participant observation and narrative interviews were conducted individually with 12 older adults with depression in care-based and daily life settings. The data obtained were subjected to thematic analysis using the narrative method to extract themes and subthemes. RESULTS: A total of three themes and 12 subthemes were elucidated. Strengths found to promote the recovery process in older adults with depression were (i) a sense of emotional connection, (ii) dialogue with life and (iii) discovery. CONCLUSIONS: Strengths promoting the recovery process from a whole-person perspective were clarified by conceptualising the experiences of older adults with depression with a strength orientation. A sense of emotional connection constituted a basis for promoting the recovery process. Dialogue with life and discovery were thought to represent the wisdom and spirituality found in the experience of old age and depression. RELEVANCE TO CLINICAL PRACTICE: While regarding the results of this study as basic knowledge, focusing on subjects' individual narratives of illness and recovery will open the possibility of a strength-oriented nursing practice for older adults with depression and lead to the provision of care that promotes recovery. PMID- 29573503 TI - Niche similarities among introduced and native mountain ungulates. AB - The niche concept provides a strong foundation for theoretical and applied research among a broad range of disciplines. When two ecologically similar species are sympatric, theory predicts they will occupy distinct ecological niches to reduce competition. Capitalizing on the increasing availability of spatial data, we built from single species habitat suitability models to a multispecies evaluation of the niche partitioning hypothesis with sympatric mountain ungulates: native bighorn sheep (BHS; Ovis canadensis) and introduced mountain goats (MTG; Oreamnos americanus) in the northeast Greater Yellowstone Area. We characterized seasonal niches using two-stage resource selection functions with a used-available design and descriptive summaries of the niche attributes associated with used GPS locations. We evaluated seasonal similarity in niche space according to confidence interval overlap of model coefficients and similarity in geographic space by comparing model predicted values with Schoener's D metric. Our sample contained 37,962 summer locations from 53 individuals (BHS = 31, MTG = 22), and 79,984 winter locations from 57 individuals (BHS = 35, MTG = 22). Slope was the most influential niche component for both species and seasons, and showed the strongest evidence of niche partitioning. Bighorn sheep occurred on steeper slopes than mountain goats in summer and mountain goats occurred on steeper slopes in winter. The pattern of differential selection among species was less prevalent for the remaining covariates, indicating similarity in niche space. Model predictions in geographic space showed broad seasonal similarity (summer D = 0.88, winter D = 0.87), as did niche characterizations from used GPS locations. The striking similarities in seasonal niches suggest that introduced mountain goats will continue to increase their spatial overlap with native bighorn. Our results suggest that reducing densities of mountain goats in hunted areas where they are sympatric with bighorn sheep and impeding their expansion may reduce the possibility of competition and disease transfer. Additional studies that specifically investigate partitioning at finer scales and along dietary or temporal niche axes will help to inform an adaptive management approach. PMID- 29573504 TI - Tree mycorrhizal type predicts within-site variability in the storage and distribution of soil organic matter. AB - Forest soils store large amounts of carbon (C) and nitrogen (N), yet how predicted shifts in forest composition will impact long-term C and N persistence remains poorly understood. A recent hypothesis predicts that soils under trees associated with arbuscular mycorrhizas (AM) store less C than soils dominated by trees associated with ectomycorrhizas (ECM), due to slower decomposition in ECM dominated forests. However, an incipient hypothesis predicts that systems with rapid decomposition-e.g. most AM-dominated forests-enhance soil organic matter (SOM) stabilization by accelerating the production of microbial residues. To address these contrasting predictions, we quantified soil C and N to 1 m depth across gradients of ECM-dominance in three temperate forests. By focusing on sites where AM- and ECM-plants co-occur, our analysis controls for climatic factors that covary with mycorrhizal dominance across broad scales. We found that while ECM stands contain more SOM in topsoil, AM stands contain more SOM when subsoil to 1 m depth is included. Biomarkers and soil fractionations reveal that these patterns are driven by an accumulation of microbial residues in AM dominated soils. Collectively, our results support emerging theory on SOM formation, demonstrate the importance of subsurface soils in mediating plant effects on soil C and N, and indicate that shifts in the mycorrhizal composition of temperate forests may alter the stabilization of SOM.

AB - PURPOSE: Removable denture hygiene care is very important for the longevity of the rehabilitation treatment; however, it is necessary to analyze the effects that denture cleansers can cause on the surfaces of prostheses. Thus, this study evaluated the effect of alkaline peroxide-effervescent tablets on the surface of cobalt-chromium alloys (Co-Cr) used in removable partial dentures. MATERIALS AND METHODS: Circular metallic specimens (12 * 3 mm) were fabricated and were immersed (n = 16) in: control, Polident 3 Minute (P3M), Steradent (S), Efferdent (E), Polident for Partials (PFP), and Corega Tabs (CT). The surface roughness (MUm) (n = 10) was measured before and after periods of cleanser immersion corresponding to 0.5, 1, 2, 3, 4, and 5 years. Ion release was analyzed (n = 5) for Co, Cr, and molybdenum (Mo). Scanning electron microscopy (SEM) analysis and an Energy-dispersive X-ray spectroscopy (EDS) were conducted in one specimen. The surface roughness data were statistically analyzed (alpha = 0.05) with the Kruskal-Wallis test to compare the solutions, and the Friedman test compared the immersion durations. Ion release analysis was performed using 2-way ANOVA and Tukey's test. RESULTS: There was no significant surface roughness difference when comparing the solutions (p > 0.05) and the immersion durations (p = 0.137). Regarding ion release (MUg/L), CT, E, and control produced a greater release of Co ions than S (p < 0.05). CT produced a greater release of Cr ions than control, S, and P3M (p < 0.05). Finally, E caused the greatest release of Mo ions (p < 0.05). SEM confirmed that the solutions did not damage the surfaces and EDS confirmed that there were no signs of oxidation. CONCLUSION: The various solutions tested did not have any deleterious effects on the Co-Cr alloy surface. Steradent, however, presented the smallest ionic release.

PMID- 29573506 TI - Analysis of current perioperative management with Haemate(r) P/Humate P(r) in von Willebrand disease: Identifying the need for personalized treatment. AB - INTRODUCTION: Patients with Von Willebrand disease (VWD) are regularly treated with VWF-containing concentrates in case of acute bleeding, trauma and dental or surgical procedures. AIM: In this multicentre retrospective study, current perioperative management with a von Willebrand factor (VWF)/Factor VIII (FVIII) concentrate (Haemate(r) P) in patients with VWD was evaluated. PATIENTS/METHODS: Patients with VWD undergoing minor or major surgery between 2000 and 2015, requiring treatment with a VWF/FVIII concentrate (Haemate(r) P), were included. Achieved VWF activity (VWF:Act) and FVIII during FVIII-based treatment regimens were compared to predefined target levels in national guidelines. RESULTS: In total, 103 patients with VWD (148 surgeries) were included: 54 type 1 (73 surgeries), 43 type 2 (67 surgeries) and 6 type 3 (8 surgeries). Overall, treatment resulted in high VWF:Act and FVIII levels, defined as >=0.20 IU/mL above predefined levels. In patients with type 1 VWD, respectively, 65% and 91% of trough VWF:Act and FVIII levels were higher than target levels. In patients with type 2 and type 3 VWD, respectively, 53% and 57% of trough VWF:Act and 72% and 73% of trough FVIII levels were higher than target level. Furthermore, FVIII accumulation over time was observed, while VWF:Act showed a declining trend, leading to significantly higher levels of FVIII than VWF:Act. CONCLUSION: High VWF:Act and accumulation of FVIII were observed after perioperative FVIII-based replacement therapy in patients with VWD, both underlining the necessity of personalization of dosing regimens to optimize perioperative treatment. PMID- 29573508 TI - Anthropogenic disturbance equalizes diversity levels in arbuscular mycorrhizal fungal communities. AB - The arbuscular mycorrhizal (AM) symbiosis is a key plant-microbe interaction in sustainable functioning ecosystems. Increasing anthropogenic disturbance poses a threat to AM fungal communities worldwide, but there is little empirical evidence about its potential negative consequences. In this global study, we sequenced AM fungal DNA in soil samples collected from pairs of natural (undisturbed) and anthropogenic (disturbed) plots in two ecosystem types (10 naturally wooded and six naturally unwooded ecosystems). We found that ecosystem type had stronger directional effects than anthropogenic disturbance on AM fungal alpha and beta diversity. However, disturbance increased alpha and beta diversity at sites where natural diversity was low and decreased diversity at sites where natural diversity was high. Cultured AM fungal taxa were more prevalent in anthropogenic than natural plots, probably due to their efficient colonization strategies and ability to recover from disturbance. We conclude that anthropogenic disturbance does not have a consistent directional effect on AM fungal diversity; rather, disturbance equalizes levels of diversity at large scales and causes changes in community functional structure. PMID- 29573509 TI - Multiple breath washout: A new and promising lung function test for patients with idiopathic pulmonary fibrosis. AB - BACKGROUND AND OBJECTIVE: Idiopathic pulmonary fibrosis (IPF) is a devastating progressive lung disease affecting the parenchyma. Nitrogen multiple-breath washout (N2 -MBW) is a lung function test that measures ventilation inhomogeneity, a biomarker of small airway disease. We assessed clinical properties of N2 -MBW in IPF. METHODS: In this prospective cohort pilot study, 25 IPF patients and 25 healthy controls were assessed at baseline and 10 patients at median 6.2 months later. Outcomes included the lung clearance index (LCI) from N2 -MBW, forced vital capacity (FVC) from spirometry, diffusion capacity of the lungs for carbon monoxide (DLCO ), bronchiectasis score from computed tomography scans, the Gender-Age-Physiology (GAP score for IPF) stage and death or lung transplantation (LTx). Study end points were feasibility, repeatability, discriminative capacity and correlation with disease severity and structural lung damage. RESULTS: All patients were able to perform N2 -MBW. LCI was repeatable and reproducible. Median (interquartile range (IQR)) LCI in IPF was 11.6 (10.1 13.8) in IPF versus 7.3 (6.9-8.4) in controls (P < 0.0001). LCI correlated with DLCO corrected for haemoglobin (corrDLCO ; r = -0.49, P = 0.016), bronchiectasis score (r = 0.45, P = 0.024) and the GAP stage (r = 0.59, P = 0.002), but not with FVC. FVC was not related to bronchiectasis. During follow-up, six patients died and one received LTx. LCI correlated with the latter compound outcome: hazard ratio (95% CI) was 2.43 (1.26; 4.69) per one LCI SD from the patient population. CONCLUSION: N2 -MBW is a feasible, reliable and valid lung function test in IPF. LCI correlates with diffusion impairment, structural airway damage and clinical disease severity. LCI is a promising surveillance tool in IPF that may predict mortality. PMID- 29573510 TI - Arteriovenous shunts as venous access in children with haemophilia. AB - INTRODUCTION: Venous access is essential in patients with haemophilia for administration of factor concentrates. Peripheral venipuncture may be challenging, particularly in young children or during immune tolerance induction (ITI). Central venous access devices (CVADs) carry a significant risk for complications. An alternative for venous access is peripheral arteriovenous shunts (AVSs), but there is sparse documentation in the literature. The aim of this study was to document our experience with AVS over 12 years in 27 boys with severe haemophilia. METHODS: For AVS creation, a subcutaneous vein is connected end-to-side with an artery at the wrist (Cimino) or at the forearm (Gracz shunt). Factor concentrates were substituted as for intermediate size surgery. To prevent shunt occlusion, heparin (5 units/kg/h) was given during the first 3 days. RESULTS: Indications for AVS creation were prophylaxis start (n = 20) and ITI (n = 7). Age at shunt insertion was median 1.5 years (minimum 8 months; maximum 11.7 years). Shunt maturation was achieved within a median of 3 weeks after surgery (1.5 weeks; 18 weeks). Age when home treatment was established was median 2.1 years (9 months; 11.7 years). Four patients required AVS revisions due to stenosis, but 26 of 27 patients (96%) achieved good long-term shunt function. There were few other complications. CONCLUSION: Arteriovenous shunts provide a good alternative to CVAD and carry a lower risk of complications. AVSs allow earlier start of prophylaxis and home therapy with an improved quality of life for patients and families. PMID- 29573511 TI - Effects of flask configuration on biofilm growth and metabolites of intertidal Cyanobacteria isolated from a mangrove forest. AB - AIMS: A novel approach was employed to study the growth of three cyanobacterial strains namely Oscillatoria sp. (AP17), Leptolyngbya sp. (AP3b) and Chroococcus sp. (AP3U). Furthermore, their broad metabolite profile, production of pigments, exopolysaccharide (EPS) and antimicrobial activity were evaluated in response to contrasting cultivation modes: biofilm or planktonic. METHODS AND RESULTS: The biofilm culture mode was carried out in the patented conico-cylindrical flask (CCF) and the planktonic culture mode was carried out in an Erlenmeyer flask (EF). The amount of polysaccharide that was released and that remained capsular/bound was higher in CCF compared to EF cultivation. Amount of chlorophyll a produced by Oscillatoria (AP17) was higher in the CCF compared to the EF cultivation. Highest antimicrobial activities were exhibited by Leptolyngbya (AP3b) biofilm than other biofilms as well as planktonic biomass. Metabolite profiles of Cyanobacteria were revealed by various chromatographic techniques and showed clear differences among the two contrasting modes of cultivation. CONCLUSIONS: The results showed clear differences in the mode of growth for achieving maximum chlorophyll a, EPS and bioactive metabolite production of the Cyanobacteria. SIGNIFICANCE AND IMPACT OF THE STUDY: The present study augmented the information which can enhance wider exploration of the biofilm mode of cultivation of Cyanobacteria. PMID- 29573512 TI - Reduced solar-induced chlorophyll fluorescence from GOME-2 during Amazon drought caused by dataset artifacts. AB - Recently, Yang et al. () reported a decrease in solar-induced chlorophyll fluorescence (SIF) during 2015/2016 El Nino event albeit the increase in enhanced vegetation index (EVI). They interpreted the reduced SIF as a signal of reduced ecosystem photosynthesis. However, we argue that the reduced SIF during 2015/2016 is caused by a decreasing trend of SIF due to sensor degradation and the satellite overpass time is critical for drought impact assessment. PMID- 29573514 TI - Grey correlations: A commentary on Chehadi et al. PMID- 29573513 TI - Filling the glass: Effects of a positive psychology intervention on executive task performance in chronic pain patients. AB - BACKGROUND: Chronic pain is associated with emotional problems as well as difficulties in cognitive functioning. Prior experimental studies have shown that optimism, the tendency to expect that good things happen in the future, and positive emotions can counteract pain-induced task performance deficits in healthy participants. More specifically, induced optimism was found to buffer against the negative effects of experimental pain on executive functioning. This clinical experiment examined whether this beneficial effect can be extended to a chronic pain population. METHODS: Patients (N = 122) were randomized to a positive psychology Internet-based intervention (PPI; n = 74) or a waiting list control condition (WLC; n = 48). The PPI consisted of positive psychology exercises that particularly target optimism, positive emotions and self compassion. RESULTS: Results demonstrated that patients in the PPI condition scored higher on happiness, optimism, positive future expectancies, positive affect, self-compassion and ability to live a desired life despite pain, and scored lower on pain catastrophizing, depression and anxiety compared to patients in the WLC condition. However, executive task performance did not improve following completion of the PPI, compared to the WLC condition. CONCLUSIONS: Despite the lack of evidence that positive emotions and optimism can improve executive task performance in chronic pain patients, this study did convincingly demonstrate that it is possible to increase positive emotions and optimism in chronic pain patients with an online positive psychology intervention. It is imperative to further explore amendable psychological factors that may reduce the negative impact of pain on executive functioning. SIGNIFICANCE: We demonstrated that an Internet-based positive psychology intervention strengthens optimism and positive emotions in chronic pain patients. These emotional improvements are not associated with improved executive task performance. As pain itself often cannot be relieved, it is imperative to have techniques to reduce the burden of living with chronic pain. PMID- 29573515 TI - Knowledge expectations of orthopaedic patients. AB - AIM: To describe and compare knowledge expectations and received knowledge in elective orthopaedic surgery patients. BACKGROUND: Population aging, increasing incidence of osteoarthritis, the growing number of surgical procedures, and reduced clinical stays underline the need for a new approach to patient education. DESIGN: This study has a descriptive, comparative design. METHODS: Data were collected from 263 patients who had total hip and knee replacement elective surgery during 3 years (2009-2012) in 5 public hospitals in Spain. The Knowledge Expectation of Hospital Patients and the Received Knowledge of Hospital Patients Scales were used to collect data. The questionnaires were filled before hospital admission, at discharge and at follow-up 6 to 7 months later. RESULTS: Surgical patients received less knowledge than they expected. Patients' expectations were only met in the functional dimension. At follow-up, patients reported that they perceived having acquired more knowledge during their hospital stay than they reported at the time of discharge. Knowledge expectations and knowledge received were related to employment status, gender, and previous contact experience with the hospital. CONCLUSION: Knowledge expectations were not met, and results showed the need to improve education for orthopaedic patients throughout the perioperative process, not only during hospitalization.

PMID- 29573517 TI - Medical Certificates of Cause of Death for people with intellectual disabilities: A systematic literature review. AB - BACKGROUND: Mortality studies can help reduce health inequalities by informing public policy through a better understanding of causes of death and comorbidities. Mortality studies often rely on Medical Certificates of Cause of Death (MCCD) for data. METHOD: A systematic review was undertaken to identify the extent and nature of issues in recording causes of death for people with intellectual disability on MCCD. RESULTS: Fifteen of the 25 articles included in the literature review raised concerns about the accuracy of MCCD in identifying the cause(s) of death of people with intellectual disability. The most frequent issues were the under-reporting of intellectual disability on MCCD, and listing intellectual disability or an associated condition as an underlying cause of death. CONCLUSIONS: Concerns about the accuracy and reliability of MCCD for people with intellectual disability raise questions about mortality data based on MCCD. Clear guidance is required from WHO for those completing MCCD for people with intellectual disability. PMID- 29573518 TI - Oxygen uptake rate in alginate producer (algU+) and nonproducer (algU-) strains of Azotobacter vinelandii under nitrogen-fixation conditions. AB - AIMS: The sigma E (AlgU) in Azotobacter vinelandii has been shown to control the expression of cydR gene, a repressor of genes of the alternative respiratory chain, and alginate has been considered a barrier for oxygen diffusion. Therefore, the aim of the present study was to compare the respiratory activity of an alginate nonproducing strain, lacking the sigma factor E (algU-), and polymer-producing strains (algU+) of A. vinelandii under diazotrophic conditions at different aeration conditions. METHODS AND RESULTS: Our results reveal that under diazotrophic and high aeration conditions, A. vinelandii strain OP (algU-) had a specific oxygen consumption rate higher (30 and 54%) than those observed in the OP algU+-complemented strain, named OPAlgU+, and the ATCC 9046 respectively. However, the specific growth rate and biomass yields (based on oxygen and sucrose) were lower for OP cultivations as compared to the algU+ strains. These differences were partially explained by an increase in 1.5-fold of cydA relative expression in the OP strain, as compared to that obtained in the isogenic OPAlgU+ strain. CONCLUSIONS: Overall, our results confirm the important role of algU gene on the regulation of respiratory metabolism under diazotrophic growth when A. vinelandii is exposed to high aeration. SIGNIFICANCE AND IMPACT OF THE STUDY: This study highlights the role of AlgU to control respiration of A. vinelandii when exposed to diazotrophy. PMID- 29573519 TI - Sagittal abdominal diameter resembles waist circumference as a surrogate marker of insulin resistance in adolescents-Brazilian Metabolic Syndrome Study. AB - OBJECTIVE: To evaluate the association of the sagittal abdominal diameter (SAD) with insulin resistance (IR) and metabolic syndrome (MetS) components, and to compare SAD with waist circumference (WC). SUBJECTS/METHODS: This was a multicenter, cross-sectional study of 520 adolescents (10- to 18-years old). IR was assessed using the homeostasis model assessment of IR (HOMA-IR) and the hyperglycaemic clamp (n = 76). RESULTS: SAD and WC were positively correlated with HOMA-IR (r = 0.637 and r = 0.653) and inversely correlated with the clamp derived insulin sensitivity index (ISI) (r = -0.734 and r = -0.731); P < .001. In the multivariable linear regression analysis, SAD was positively associated with HOMA-IR (B = 0.046 +/- 0.003) and inversely associated with the clamp-derived ISI (B = -0.084 +/- 0.009) after adjusting for sex, age, and Tanner's stages (P < .001). When WC replaced the SAD, it was positively associated with HOMA-IR (B = 0.011 +/- 0.001) and inversely associated with the clamp-derived ISI (B = -0.018 +/- 0.002); P < .001. The values of the areas under the curves (AUC) were 0.823 and 0.813 for SAD and WC, respectively. In Bland-Altman analysis, there were agreement between both, SAD and WC, with the clamp-derived ISI (mean = 0.00; P > .05). The SAD and WC were positively associated with blood pressure, triglycerides, and uric acid, and inversely associated with high-density lipoprotein (HDL)-cholesterol after adjusting for sex, age, and Tanner's stages. CONCLUSION: The SAD was associated with IR and MetS components, with a good discriminatory power for detecting IR. When compared to WC, SAD showed equivalent results. PMID- 29573520 TI - Bronchiectasis in the Kimberley region of Western Australia. AB - OBJECTIVE: To review the work-up and inpatient management of non-cystic fibrosis bronchiectasis exacerbations against best practice guidelines in the Kimberley, a remote region of Western Australia, with the ultimate goal of improving treatment in the region.^ DESIGN: Retrospective cohort study and audit of remote adult bronchiectasis hospital admissions between 2011 and 2016. SETTING: Remote hospital inpatients. PARTICIPANTS: Thirty-two patients and 110 hospital admissions were included. Patients were >=15 years old, had computed tomography confirmed bronchiectasis and at least one hospital admission for acute respiratory illness prior to January 2011. MAIN OUTCOMES MEASURED: The 5-year mortality and compliance to a Lung Foundation position statement on non-cystic fibrosis bronchiectasis which suggests investigating for an underlying cause at diagnosis and during exacerbations prolonged antibiotics (10-14 days) and prolonged hospital admissions (>=7 days) are required. RESULTS: The overall 5 year mortality was 21.8%, with the median age at death of 37 years (interquartile range, 27-63). The median duration of hospital admission was shorter than the recommended 3 days (interquartile range, 2-5) with 11 of 100 (11%) patients admitted for >=7 days. The median duration of antibiotics was also shorter than the recommended 7 days (interquartile range, 4-10), with 31 of the 98 (32%) patients prescribed >=10 days and 6 of the 98 (6%) prescribed >=14 days of therapy. CONCLUSION: We found under-treatment and under-investigation of non cystic fibrosis bronchiectasis in the Kimberley region. Five-year mortality was high, consistent with other rural Australian Indigenous cohorts.S Following this audit, a strategy to improve awareness, as well as update and promote regional guidelines has been developed. PMID- 29573521 TI - Activation of the IGF1 receptor stimulates glycogen synthesis by mink uterine epithelial cells. AB - Glycogen synthesis by mink uterine epithelial cells is stimulated by estradiol (E2 ) during estrus, although the mechanism/s through which the steroid promotes glycogen accumulation are unknown. Our aim was to determine if insulin is required for E2 induced glycogen synthesis by an immortalized mink uterine epithelial cell line (GMMe). We show that the cells expressed the genes for glycogen metabolizing enzymes (hexokinase 1, glucose-6-phosphatase 3, glycogen synthase 1, and glycogen phosphorylase-muscle), receptors for insulin, insulin like growth factor 1 and E2 (Esr1). Interestingly, treatment of cells with E2 alone failed to stimulate glycogen production, whereas supraphysiological concentrations of insulin (50 MUg/ml) only, significantly increased glycogen content. Moreover, insulin + E2 increased glycogen content when compared to insulin alone (p < 0.05), an affect that was blocked when cells were treated with the pure E2 receptor antagonist ICI 182,780. Glycogen synthesis in response to insulin was significantly inhibited when cells were pre-treated with picropodophyllotoxin, an IGF1R antagonist. Treatment of cells with LY294002, a phosphatidylinositol 3-kinase (PI3K) antagonist, blocked insulin's effects on glycogen production whereas treatment with U0126, an inhibitor of mitogen activated kinase-kinase (MEK1/2) was without effect. These findings suggest to us that the affects of E2 on glycogen synthesis by GMMe cells is mediated through Esr1 and increased responsiveness of the cells to insulin. Because picropodophylotoxin blocked the effects of insulin on glycogen production, and both insulin and IGF1 act through PI3K, it is possible that IGF1 plays a role in glycogen production by these cells. PMID- 29573522 TI - Liver kinase B1 suppresses growth of lung cancer cells through sonic hedgehog signaling pathway. AB - Lung cancer is one of life-threatening cancers in the worldwide. Liver kinase B1 (LKB1) has been reported to be closely related to cancers; however, the underlying mechanism of LKB1 in lung cancer remains unclear. In our study, a LKB1 specific shRNA was employed to down-regulate LKB1 levels and a LKB1 over expression plasmid was constructed to up-regulate LKB1 levels. Thereafter, growth of lung cancer cells was assessed by MTT assay and flow cytometry. Effects of LKB1 on the activation of sonic hedgehog (Shh) signaling pathway were detected by Western blot. Effects of LKB1 on lung cancer growth and Shh signaling pathway activation were also assessed in vivo. Our results showed that LKB1 inhibited proliferation of lung cancer cells and induced their apoptosis. Moreover, LKB1 inhibited Shh signaling pathway activation. Our in vivo study also showed that LKB1 inhibited lung cancer growth in vivo and modulated Shh signaling pathway. Treatment with cyclopamine, a Shh signaling pathway inhibitor, reversed the effects of LKB1 silencing and enhanced the effects of LKB1 over-expression. Results of our study demonstrate that LKB1 inhibits lung cancer growth in vitro and in vivo through Shh signaling pathway. PMID- 29573523 TI - Presenting predictors and temporal trends of treatment-related outcomes in diabetic ketoacidosis. AB - OBJECTIVE: This study examines temporal trends in treatment-related outcomes surrounding a diabetic ketoacidosis (DKA) performance improvement intervention consisting of mandated intensive care unit admission and implementation of a standardized management pathway, and identifies physical and biochemical characteristics associated with outcomes in this population. METHODS: A retrospective cohort of 1225 children with DKA were identified in the electronic health record by international classification of diseases codes and a minimum pH less than 7.3 during hospitalization at a quaternary children's hospital between April, 2009 and May, 2016. Multivariable regression examined predictors and trends of hypoglycemia, central venous line placement, severe hyperchloremia, head computed tomography (CT) utilization, treated cerebral edema and hospital length of stay (LOS). RESULTS: The incidence of severe hyperchloremia and head CT utilization decreased during the study period. Among patients with severe DKA (presenting pH < 7.1), the intervention was associated with decreasing LOS and less variability in LOS. Lower pH at presentation was independently associated with increased risk for all outcomes except hypoglycemia, which was associated with higher pH. Patients treated for cerebral edema had a lower presenting mean systolic blood pressure z score (0.58 [95% confidence interval (CI) -0.02-1.17] vs 1.23 [1.13-1.33]) and a higher maximum mean systolic blood pressure (SBP) z score during hospitalization (3.75 [3.19-4.31] vs 2.48 [2.38-2.58]) compared to patients not receiving cerebral edema treatment. Blood pressure and cerebral edema remained significantly associated after covariate adjustment. CONCLUSION: Treatment-related outcomes improved over the entire study period and following a performance improvement intervention. The association of SBP with cerebral edema warrants further study.

AB - Heparin is a highly sulfated glycosaminoglycan (GAG) of natural origin used as an anticoagulant and antithrombotic drug. These properties are principally based on the binding and activation of antithrombin (AT) through the pentasaccharide sequence GlcNAc/NS,6S-GlcA-GlcNS,3,6S-IdoA2S-GlcNS,6S (AGA*IA). Literature data show that the population of the 2 S0 ring conformation of the 2-O-sulfo-alpha-l iduronic acid (IdoA2S) motif correlates with the affinity and activation of AT. It was recently demonstrated that two synthetic AGA*IA-containing hexasaccharides (one G unit added at the reducing end), differing in the degree of sulfation of the IdoA unit, show comparable affinity and ability to activate AT, despite a different conformation of the IdoA residue. In this paper, the binding of these two glycans to AT was studied by isothermal titration microcalorimetry (ITC), transferred (tr-) NOESY, saturation transfer difference (STD) NMR spectroscopy and molecular dynamics (MD) simulations. Results indicated that both the IdoA2S and the IdoA units assume a 2 S0 conformation when bound with AT, and so present a common binding epitope for the two glycans, centred on the AGA*IA sequence.

PMID- 29573528 TI - Reversible Magnetic Agglomeration: A Mechanism for Thermodynamic Control over Nanoparticle Size. AB - We present a method for the synthesis and precise size control of magnetic nanoparticles in a reversible magnetic agglomeration mechanism. In this approach, nanoparticles nucleate and grow until a critical susceptibility is reached, in which magnetic attraction overcomes dispersive forces, leading to agglomeration and precipitation. This phase change in the system arrests nanoparticle growth and gives true thermodynamic control over the size of nanoparticles. We then show that increasing the alkyl chain length of the surfactant, and hence increasing steric stabilization, allows nanoparticles to grow to larger sizes before agglomeration occurs. Therefore, simply by choosing the correct surfactant, the size and magnetic properties of iron nanoparticles can be tailored for a particular application. With the continuous addition of the precursor solution, we can repeat the steps of nucleation, growth, and magnetic agglomeration indefinitely, making the approach suitable for large scale syntheses. PMID- 29573529 TI - Effects of the SGLT-2 inhibitor dapagliflozin on glomerular and tubular injury markers. AB - The mechanisms by which SGLT-2 inhibitors lower albuminuria are incompletely understood. We assessed in a post-hoc analysis of a cross-over trial the effects of the SGLT2 inhibitor dapagliflozin on glomerular markers (IgG to IgG4 and IgG to albumin), tubular markers (urinary KIM-1, NGAL and LFABP) and inflammatory markers (urinary MCP-1 and IL-6) to provide more insight into kidney protective effects. Dapagliflozin decreased albuminuria by 43.9% (95% CI, 30.3%-54.8%) and eGFR by 5.1 (2.0-8.1) mL/min/1.73m2 compared to placebo. Dapagliflozin did not change glomerular charge or size selectivity index compared to placebo. Dapagliflozin decreased urinary KIM-1 excretion by 22.6% (0.3%-39.8%; P = .05) and IL-6 excretion by 23.5% (1.4%-40.6%; P = .04) compared to placebo, whereas no changes in NGAL, LFABP and MCP-1 were observed. During dapagliflozin treatment, changes in albuminuria correlated with changes in eGFR (r = 0.36; P = .05) and KIM-1 (r = 0.39; P = .05). In conclusion, the albuminuria-lowering effect of 6 weeks of dapagliflozin therapy may be the result of decreased intraglomerular pressure or reduced tubular cell injury.

PMID- 29573530 TI - Knee extensor strength assessed using a vertical squat and a simple geometric model to calculate joint torque: An evaluation of validity and clinical utility. AB - AIM: We propose a simple method to measure knee extensor muscle strength using a single-legged vertical squat. The purpose of the present study was to assess the validity of this method in comparison with standard methods of measurement. METHODS: A total of 30 healthy adults (mean age 22 years) and 28 healthy older individuals (mean age 69 years) participated in this study. Knee extensor torque at maximum knee flexion during a single-leg squat was calculated by a geometrical model using height, weight and measured leg forward lean angle. Its validity as a measurement of knee extensor strength was assessed by comparing the results with maximum isometric knee extensor strength measured using an isokinetic dynamometer and a handheld dynamometer. RESULTS: Knee extensor torques calculated by the squat model were highly correlated with those calculated by the isokinetic dynamometer (r = 0.835) and handheld dynamometer (r = 0.884); however, the difference between the squat model and the isokinetic dynamometer measurements, and between the squat model and the handheld dynamometer measurements increased proportionally with increasing muscle strength. CONCLUSION: The squat model is a convenient way to measure knee extensor muscle strength quantitatively. However, it might be more suitable for individuals with quadriceps muscle weakness than for those with strong muscles. Geriatr Gerontol Int 2018; 18: 1125-1131.

AB - An iridium-catalyzed regioselective sequential silylation and borylation of heteroarenes was developed, which represents a rare example of unsymmetrical intermolecular C-H bond difunctionalization through the introduction of two different functionalities during a one-pot transformation. Although the substrate scope for the dehydrogenative silylation of heteroarenes has been limited mainly to electron-rich five-membered rings, the current reaction proceeds with both electron-rich and electron-deficient heteroarenes with the aid of heteroatom directing C-H bond activation. The regioselectivity of the second borylation was controlled by both steric factors and the electronic effect of the silyl group installed in the first step. In combination with the classic cross-coupling reaction, this method provides rapid access to multisubstituted heteroarenes. PMID- 29573534 TI - A [3]Rotaxane Host Selects Between Stereoisomers. AB - What has it got in its pockets? A new approach to the selective binding and reporting of stereoisomers using mechanical bonding to produce a well-defined three-dimensional binding pocket was recently reported by Beer and co-workers. The highly stereoselective binding of stereoisomers by the reported [3]rotaxane suggest that the use of the mechanical bond to engineer a binding pocket has great potential for the development of stereoselective hosts.

AB - OBJECTIVES: Following clearance of incident hepatitis C virus (HCV) infections, HCV antibody levels may decline, resulting in seroreversion. It is unclear to what extent HCV antibody level trajectories differ between patients with treatment-induced sustained virological response (SVR), those with spontaneous clearance and those with untreated replicating HCV infection. We investigated HCV antibody level dynamics in HIV-infected MSM with different clinical outcomes. METHODS: We investigated anti-HCV antibody level dynamics following an incident HCV infection in 67 HIV-infected men who have sex with men (MSM) with different clinical outcomes: SVR (n = 33), spontaneous clearance (n = 12), and untreated replicating infection (n = 22). Antibody levels were measured at the time of HCV diagnosis, and at yearly intervals for 3 years thereafter. RESULTS: At baseline, median HCV antibody levels were similar in the three groups: 13.4, 13.8 and 13.5 sample to cut-off (S/CO) for SVR, spontaneous clearance and untreated infection, respectively. Over 3 years of follow-up, SVR was associated with a more pronounced decrease in anti-HCV levels compared with spontaneous clearance and untreated infection [median decline 71% [interquartile range (IQR: 43-87%), 38% (IQR: 29-60%) and 12% (IQR: 9-22%), respectively; P < 0.001]. Seroreversions occurred in five of 33 (15%) patients with SVR and in one of 12 (8%) with spontaneous clearance. A shorter delay between time of infection and treatment start correlated with higher rates of decline in antibody levels. Seven patients experienced a reinfection. CONCLUSIONS: Treatment-induced HCV clearance was associated with a more pronounced decline in anti-HCV antibody levels and with higher rates of seroreversion compared with spontaneous clearance or untreated replicating HCV infection among HIV-infected MSM with incident HCV infections. Rapid clearance of HCV RNA following early HCV treatment might impair the development of persistent antibody titres. PMID- 29573535 TI - Prevalence and risk factors of measles seronegativity in a cohort of HIV-positive subjects: a retrospective study. AB - OBJECTIVES: Measles infection is a vaccine-preventable disease currently resurging in Europe. HIV-infected subjects are at higher risk of complications following measles infection. We investigated the risk factors associated with being seronegative in a cohort of HIV-infected subjects. METHODS: All HIV infected subjects in our cohort who had a measles serological test performed between December 2005 and May 2017 were retrospectively identified. A measles immunoglobulin G (IgG) titre > 275 mIU/mL was considered protective. Risk factors were analysed using logistic regression. RESULTS: Measles serology was available in 273 of 3124 subjects in active follow-up (8.7%). The prevalence of measles seronegativity was 21.6% (59 of 273). In the univariate analysis, being born after 1970 and HIV infection by vertical transmission were both associated with a higher risk of measles seronegativity, while a nadir CD4 T-cell count < 200 cells/MUL was associated with a lower risk of measles seronegativity. In the multivariate analysis, only being born after 1970 [odds ratio (OR) 4.9; 95% confidence interval (CI) 1.3-18.7] and vertical transmission (OR 7.7; 95% CI 3.3 18.3) were significantly associated with seronegativity. Among the vertically infected subjects with measles-mumps-rubella (MMR) immunization documentation, the median number of doses of vaccine received before testing was 2 (range 1-3). CONCLUSIONS: HIV-infected subjects born after 1970 and vertically infected subjects should be screened for measles seropositivity. PMID- 29573536 TI - Outcome of surgery for recurrent anal cancer: results from a tertiary referral centre. AB - AIM: Chemoradiotherapy remains the first line of treatment for anal cancer with surgery reserved for cancer recurrence or persistence. The low incidence of anal cancer means that the numbers undergoing surgery is small with centralization for excision to regional cancer centres. We present our experience of abdominal perineal excision, with reconstruction of the perineal defect (APERR), within a tertiary centre. METHOD: Over a 15-year period, data were collected retrospectively from notes of patients who underwent an APERR. The aim was to look at disease-free and overall survival and complications associated with flap reconstruction. RESULTS: In the study period, 29 patients [median age = 62 (range: 42-81; interquartile range: 54-68) years] underwent APERR. Median follow up was 77 (4-200) months. Thirteen patients died during follow-up; eight from their disease, with a median survival time of 16 (4-63) months. Five-year survival was 67%. Nine (31%) patients had recurrence during the follow up period; this was local (n = 2), regional (n = 4), distant (n = 2) or a combination (n = 1). Sixteen (55%) patients developed 24 complications, including nine (31%) flap complications and 10 (34%) parastomal hernias. Flap complications were flap failure (n = 1) requiring direct closure, flap dehiscence (n = 2), necrosis of flap tip (n = 1), wound infection (n = 4) and a bulky flap (n = 1) requiring liposuction. CONCLUSION: APERR of anal cancer is a feasible technique with excellent oncological treatment and acceptable long-term complications, although a higher than expected rate of parastomal hernia was noted. PMID- 29573537 TI - Comparison of the planned one- and elective two-stent techniques in patients with coronary bifurcation lesions with or without acute coronary syndrome from the COBIS II Registry. AB - OBJECTIVES: To evaluate the impacts of stent techniques on long-term clinical outcomes after percutaneous coronary intervention (PCI) using drug-eluting stents (DES) for coronary bifurcation lesions in patients with or without acute coronary syndrome (ACS). BACKGROUND: Few studies have investigated the impacts of stent techniques for treating coronary bifurcation lesions in patients with and without ACS. METHODS: This multicenter registry enrolled 2,897 patients undergoing PCI with DES for coronary bifurcation lesions. We investigated the impacts of planned one-stent and elective two-stent techniques in patients with (n = 1,798) and those without (n = 1,099) ACS. Primary endpoint was the incidence of 3-year target-lesion failure (TLF), defined as a composite of cardiac death, spontaneous myocardial infarction, and target-lesion revascularization. RESULTS: The planned one-stent technique reduced TLF rate compared to elective two-stent technique in the ACS cohort (hazard ratio [HR] 0.49; 95% confidence interval [CI] 0.34-0.74; P = 0.001), and not in the non-ACS cohort (HR 0.61; 95% CI 0.35-1.06; P = 0.079). After propensity score matching, the planned one-stent technique had a significantly lower TLF rate (HR 0.47; 95% CI 0.29-0.74; P = 0.001) in patients with ACS, and it also showed a trend toward lower TLF rate with the planned one stent technique in patients without ACS (9.0 vs. 14.5%, HR 0.59; 95% CI 0.32 1.14; P = 0.116). CONCLUSIONS: Planned one-stenting reduced TLF in patients with ACS and it also might be beneficial in those without ACS for the treatment of coronary bifurcation lesions. PMID- 29573538 TI - Patients with spondyloarthritis are equally satisfied with follow-up by physiotherapist and rheumatologist. AB - OBJECTIVE: International guidelines recommend that patients with spondyloarthritis (SpA) have lifelong physiotherapy, as physical activity and exercise are essential for optimizing health throughout the course of the disease. The aim of the present study was to investigate if a physiotherapy-led outpatient clinic specializing in SpA could provide satisfactory follow-up as an alternative to standard visits with a rheumatologist (RT). We hypothesized that satisfaction would be similar in patients followed by a physiotherapist (PT) or an RT. METHODS: A total of 68 patients were randomized to follow-up every fourth month by a PT or RT, for three visits in total. Patient satisfaction was evaluated using the Leeds Satisfaction Questionnaire (LSQ). Function, mobility and disease activity were rated using the Bath Ankylosing Spondylitis Functional Index (BASFI), Mobility Index (BASMI) and Ankylosing Spondylitis Disease Activity Score (ASDAS). RESULTS: Patients were equally satisfied with PT and RT follow-up at the first (p = 0.062) and last (p = 0.710) visit. At the second visit, the RT group was seen by a nurse, and was more satisfied than the PT group (p = 0.015). Function deteriorated in both the PT (p = 0.014) and RT (p = 0.007) groups. Mobility increased in the PT group (p = 0.020). Disease activity was not affected. CONCLUSIONS: Patients seem to be equally satisfied with either of the follow-up regimes. The PT-led follow-up did not seem to affect the patients' course of disease negatively. The results indicate that it would be safe to implement a PT-led clinic for patients with SpA in specialist health services, but longer-term follow-up is necessary to support the findings of this study. PMID- 29573540 TI - What the neighbors say. PMID- 29573539 TI - Electrochemical Biosensor Composed of Silver Ion-Mediated dsDNA on Au Encapsulated Bi2 Se3 Nanoparticles for the Detection of H2 O2 Released from Breast Cancer Cells. AB - A newly developed electrochemical biosensor composed of a topological insulator (TI) and metallic DNA (mDNA) is fabricated. The bismuth selenide nanoparticle (Bi2 Se3 NP) is synthesized and sandwiched between the gold electrode and another Au-deposited thin layer (Bi2 Se3 @Au). Then, eight-silver-ion mediated double stranded DNA (mDNA) is immobilized onto the substrate (Bi2 Se3 @Au-mDNA) for the further detection of hydrogen peroxide. The Bi2 Se3 NP acts as the electrochemical-signal booster, while unprecedentedly its encapsulation by the Au thin layer keeps the TI surface states protected, improves its electrochemical signal stability and provides an excellent platform for the subsequent covalent immobilization of the mDNA through Au-thiol interaction. Electrochemical results show that the fabricated biosensor represents much higher Ag+ redox current (~10 times) than those electrodes prepared without Bi2 Se3 @Au. The characterization of the Bi2 Se3 @Au-mDNA film is confirmed by atomic force microscopy, scanning tunneling microscopy, and cyclic voltammetry. The proposed biosensor shows a dynamic range of 00.10 * 10-6 m to 27.30 * 10-6 m, very low detection limit (10 * 10-9 m), unique current response (1.6 s), sound H2 O2 recovery in serum, and substantial capability to classify two breast cancer subtypes (MCF-7 and MDA-MB 231) based on their difference in the H2 O2 generation, offering potential applications in the biomedicine and pharmacology fields. PMID- 29573542 TI - Pulmonary transit time derived from pulmonary angiography for the diagnosis of hepatopulmonary syndrome. AB - BACKGROUND & AIMS: Pulmonary transit time (PTT) is the transit time of blood from the right side of the heart to the left side of the heart. The aim of the present study was to evaluate the role of the PTT derived from pulmonary angiography in the diagnosis of hepatopulmonary syndrome (HPS). METHODS: From December 2014 to September 2015, all patients with chronic liver disease and/or portal hypertension undergoing a venous interventional radiologic procedure at our institution were eligible for inclusion in this prospective study. Pulmonary angiography was performed in all patients, and the PTT, which was defined as the time between opacification of the pulmonary trunk and the right border of the left atrium, was determined. RESULTS: A total of 53 patients were included, 20 of whom had a positive contrast-enhanced echocardiography result and an elevated alveolar-arterial oxygen gradient were considered to have HPS. PTT was significantly shorter in patients with HPS than in those without [median, 3.34 (interquartile range, 3.01-3.67) seconds vs 4.0 (interquartile range, 3.67-4.17) seconds; P < .001]. The area under the receiver operating characteristic curve of PTT for diagnosing HPS was 0.83 (95% confidence interval, 0.70-0.92). The optimal cut-off value of PTT for diagnosing HPS, based on Youden's index, was 3.55 seconds. The sensitivity, specificity and accuracy of PTT < 3.55 seconds for diagnosing HPS were 70%, 85% and 79% respectively. CONCLUSIONS: Pulmonary transit time derived from pulmonary angiography is useful for diagnosing HPS, especially for patients with intracardiac shunts and inadequate echocardiographic windows. PMID- 29573541 TI - Treatment of infrapopliteal post-PTA dissection with tack implants: 12-month results from the TOBA-BTK study. AB - OBJECTIVES: The Tack implant is designed for focal, minimal metal management of dissections. This study evaluated Tacks for treating postpercutaneous transluminal angioplasty (PTA) dissection in patients with below-the-knee (BTK) arterial occlusive disease. BACKGROUND: PTA is the most commonly used endovascular treatment for patients with occlusive disease of the BTK vessels. Post-PTA dissection is a significant clinical problem that results in poor outcomes, but currently there are limited treatment options for managing dissections. METHODS: This prospective, single-arm study evaluated patients with CLI and BTK lesions; 11.4% were Rutherford category (RC) 4 and 88.6% were RC 5. BTK occlusive disease was treated with standard PTA and post-PTA dissections were treated with Tack placement. The primary safety endpoint was a composite of major adverse limb events (MALE) and perioperative death (POD) at 30 days. Other endpoints included: device success; procedure success (vessel patency in the absence of MALE); freedom from clinically driven target lesion revascularization (CD-TLR); primary patency; and changes in RC. Data through 12 months are presented. RESULTS: Thirty-two of 35 (91.4%) patients had post-PTA dissection and successful deployment of Tacks. Procedural success was achieved in 34/35 (97.1%) patients with no MALEs at 30 days. The 12-month patency rate was 78.4% by vessel, 77.4% by patient, and freedom from CD-TLR was 93.5%. Significant (P < .0001) improvement from baseline was observed in RC (75% of patients improved 4 or 5 steps). CONCLUSION: Tack implant treatment of post-PTA dissection was safe and effective for treatment of BTK dissections and resulted in reasonable 12-month patency and low rates of CD-TLR. PMID- 29573543 TI - Engineering d-limonene synthase down-regulation in orange fruit induces resistance against the fungus Phyllosticta citricarpa through enhanced accumulation of monoterpene alcohols and activation of defence. AB - Terpene volatiles play an important role in the interactions between specialized pathogens and fruits. Citrus black spot (CBS), caused by the fungus Phyllosticta citricarpa, is associated with crop losses in different citrus-growing areas worldwide. The pathogen may infect the fruit for 20-24 weeks after petal fall, but the typical hard spot symptoms appear when the fruit have almost reached maturity, caused by fungal colonization and the induction of cell lysis around essential oil cavities. d-Limonene represents approximately 95% of the total oil gland content in mature orange fruit. Herein, we investigated whether orange fruit with reduced d-limonene content in peel oil glands via an antisense (AS) approach may affect fruit interaction with P. citricarpa relative to empty vector (EV) controls. AS fruit showed enhanced resistance to the fungus relative to EV fruit. Because of the reduced d-limonene content, an over-accumulation of linalool and other monoterpene alcohols was found in AS relative to EV fruit. A global gene expression analysis at 2 h and 8 days after inoculation with P. citricarpa revealed the activation of defence responses in AS fruit via the up regulation of different pathogenesis-related (PR) protein genes, probably as a result of enhanced constitutive accumulation of linalool and other alcohols. When assayed in vitro and in vivo, monoterpene alcohols at the concentrations present in AS fruit showed strong antifungal activity. We show here that terpene engineering in fruit peels could be a promising method for the development of new strategies to obtain resistance to fruit diseases. PMID- 29573544 TI - The State and Challenges of Anode Materials Based on Conversion Reactions for Sodium Storage. AB - Sodium-ion batteries (SIBs) have huge potential for applications in large-scale energy storage systems due to their low cost and abundant sources. It is essential to develop new electrode materials for SIBs with high performance in terms of energy density, cycle life, and cost. Metal binary compounds that operate through conversion reactions hold promise as advanced anode materials for sodium storage. This Review highlights the storage mechanisms and advantages of conversion-type anode materials and summarizes their recent development. Although conversion-type anode materials have high theoretical capacities and abundant varieties, they suffer from multiple challenging obstacles to realize commercial applications, such as low reversible capacity, large voltage hysteresis, low initial coulombic efficiency, large volume changes, and low cycling stability. These key challenges are analyzed in this Review, together with emerging strategies to overcome them, including nanostructure and surface engineering, electrolyte optimization, and battery configuration designs. This Review provides pertinent insights into the prospects and challenges for conversion-type anode materials, and will inspire their further study. PMID- 29573545 TI - Nanostructuring Lipophilic Dyes in Water Using Stable Vesicles, Quatsomes, as Scaffolds and Their Use as Probes for Bioimaging. AB - A new kind of fluorescent organic nanoparticles (FONs) is obtained using quatsomes (QSs), a family of nanovesicles proposed as scaffolds for the nanostructuration of commercial lipophilic carbocyanines (1,1'-dioctadecyl 3,3,3',3'-tetramethyl-indocarbocyanine perchlorate (DiI), 1,1'-dioctadecyl 3,3,3',3'-tetramethyl-indodicarbocyanine perchlorate (DiD), and 1,1'-dioctadecyl 3,3,3',3'-tetramethyl-indotricarbocyanine iodide (DiR)) in aqueous media. The obtained FONs, prepared by a CO2 -based technology, show excellent colloidal- and photostability, outperforming other nanoformulations of the dyes, and improve the optical properties of the fluorophores in water. Molecular dynamics simulations provide an atomistic picture of the disposition of the dyes within the membrane. The potential of QSs for biological imaging is demonstrated by performing superresolution microscopy of the DiI-loaded vesicles in vitro and in cells. Therefore, fluorescent QSs constitute an appealing nanomaterial for bioimaging applications. PMID- 29573546 TI - Nanostructure and Microstructure Fabrication: From Desired Properties to Suitable Processes. AB - When designing a new nanostructure or microstructure, one can follow a processing based manufacturing pathway, in which the structure properties are defined based on the processing capabilities of the fabrication method at hand. Alternatively, a performance-based pathway can be followed, where the envisioned performance is first defined, and then suitable fabrication methods are sought. To support the latter pathway, fabrication methods are here reviewed based on the geometric and material complexity, resolution, total size, geometric and material diversity, and throughput they can achieve, independently from processing capabilities. Ten groups of fabrication methods are identified and compared in terms of these seven moderators. The highest resolution is obtained with electron beam lithography, with feature sizes below 5 nm. The highest geometric complexity is attained with vat photopolymerization. For high throughput, parallel methods, such as photolithography (~101 m2 h-1 ), are needed. This review offers a decision-making tool for identifying which method to use for fabricating a structure with predefined properties. PMID- 29573547 TI - Carbon-Nanosheet Based Large-Area Electrochemical Capacitor that is Flexible, Foldable, Twistable, and Stretchable. AB - With the growing demand for wearable electronics, developing new compatible energy systems is a prominent topic of research. Energy systems mounted on wearable electronics should exhibit high cost efficiency, mechanical robustness, and high electrochemical activity. Herein, all-carbon-based large-area nanocomposites for freely deformable electrochemical capacitors are suggested to address these requirements. The three-dimensionally integrated, self-supported nanocomposites consist of activated carbons (ACs) distributed in direct spinning derived carbon nanotube (DS-CNT) sheets without any additives, including conducting agents or binders. Owing to synergetic effects of the highly porous AC particles, high electron transport kinetics of CNTs, and facile ion accessibility resulting from acid treatment, the nanocomposites show a greatly improved specific capacitance of 128 F g-1 , compared to that of pristine ACs (62 F g-1 ), based on the total mass of the electrodes. The exceptional mechanical stability of the nanocomposites, which are attached on prestretched elastomer substrates, is confirmed; only a ~15% increase in the electrical resistance is observed under a tensile strain of 100%, and the initial resistance is fully recovered after releasing. Finally, the outstanding durability and electrochemical performance of the deformable all-carbon-based symmetric capacitors under various mechanical deformations of bending, folding, twisting, and stretching are successfully demonstrated.

AB - High-performance of lithium-ion batteries (LIBs) rely largely on the scrupulous design of nanoarchitectures and smart hybridization of bespoke active materials. In this work, the pine-needle-like Cu-Co skeleton is reported to support highly active Li4 Ti5 O12 (LTO) forming Cu-Co/LTO core-branch arrays via a united hydrothermal-atomic layer deposition (ALD) method. ALD-formed LTO layer is uniformly anchored on the pine-needle-like heterostructured Cu-Co backbone, which consists of branched Co nanowires (diameters in 20 nm) and Cu nanowires (250-300 nm) core. The designed Cu-Co/LTO core-branch arrays show combined advantages of large porosity, high electrical conductivity, and good adhesion. Due to the unique positive features, the Cu-Co/LTO electrodes are demonstrated with enhanced electrochemical performance including excellent high-rate capacity (155 mAh g-1 at 20 C) and noticeable long-term cycles (144 mAh g-1 at 20 C after 3000 cycles). Additionally, the full cell assembled with activated carbon positive electrode and Cu-Co/LTO negative electrode exhibits high power/energy densities (41.6 Wh kg 1 at 7.5 kW kg-1 ). The design protocol combining binder-free characteristics and array configuration opens a new door for construction of advanced electrodes for application in high-rate electrochemical energy storage. PMID- 29573549 TI - Probing Adsorption Behaviors of BSA onto Chiral Surfaces of Nanoparticles. AB - Chiral properties of nanoscale materials are of importance as they dominate interactions with proteins in physiological environments; however, they have rarely been investigated. In this study, a systematic investigation is conducted for the adsorption behaviors of bovine serum albumin (BSA) onto the chiral surfaces of gold nanoparticles (AuNPs), involving multiple techniques and molecular dynamic (MD) simulation. The adsorption of BSA onto both L- and D chiral surfaces of AuNPs shows discernible differences involving thermodynamics, adsorption orientation, exposed charges, and affinity. As a powerful supplement, MD simulation provides a molecular-level understanding of protein adsorption onto nanochiral surfaces. Salt bridge interaction is proposed as a major driving force at protein-nanochiral interface interaction. The spatial distribution features of functional groups (?COO- , ?NH3+ , and ?CH3 ) of chiral molecules on the nanosurface play a key role in the formation and location of salt bridges, which determine the BSA adsorption orientation and binding strength to chiral surfaces. Sequentially, BSA corona coated on nanochiral surfaces affects their uptake by cells. The results enhance the understanding of protein corona, which are important for biological effects of nanochirality in living organisms. PMID- 29573550 TI - Relative quantification of beta-adrenergic receptor in peripheral blood cells using flow cytometry. AB - Beta-adrenergic receptors (beta-ARs) play a critical role in many diseases. Quantification of beta-AR density may have clinical implications in terms of assessing disease severity and identifying patients who could potentially benefit from beta-blocker therapy. Classical methods for beta-AR quantification are based on labor-intensive and time-consuming radioligand binding assays. Here, we report optimization of a flow cytometry-based method utilizing a biotinylated beta-AR ligand alprenolol as a probe and use of this method to quantify relative receptor expression in healthy controls (HC). QuantumTM MESF beads were used for quantification in absolute fluorescence units. The probe was chemically modified by adding a spacer moiety between biotin and alprenolol to stabilize receptor binding, thus preventing binding decay. Testing of three different standard cell fixation and permeabilization methods (formaldehyde fixation and saponin, Tween 20, or Triton-X 100 permeabilization) showed that the formaldehyde/Triton-X 100 method yielded the best results. beta-AR expression was significantly higher in granulocytes compared to mononuclear cells. These data show that flow cytometric quantification of relative beta-AR expression in circulating leukocytes is a suitable technology for large-scale clinical application.

AB - A 66-year-old man with cryptogenic cirrhosis secondary to nonalcoholic steatohepatitis presented for orthotopic liver transplantation. Following organ reperfusion, the patient developed vasoplegic syndrome, with arterial blood pressures of approximately 60-70/30-40 mm Hg (mean arterial pressure [MAP] <45 mm Hg) for >90 minutes. He required high-dose norepinephrine and vasopressin infusions, as well as i.v. bolus doses of norepinephrine and vasopressin to reach a goal MAP> 60 mm Hg. There was minimal response to a 2 mg/kg i.v. bolus of methylene blue. Following the administration of 5 g of i.v.hydroxocobalamin, the patient had a profound improvement in arterial blood pressure, with subsequent discontinuation of the vasopressin infusion and rapid reduction of norepinephrine infusion from 20 to 2 MUg/min. While there have been several reports of the efficacy of hydroxocobalamin for vasoplegia after cardiopulmonary bypass, there have been only limited cases of hydroxocobalamin used in liver transplantation, and none with high-dose administration. We present a case of vasoplegic syndrome during liver transplantation that was refractory to high-dose vasopressors and methylene blue but responsive to high-dose i.v. hydroxocobalamin. PMID- 29573552 TI - How to Evaluate the Quality of Toxicokinetic-Toxicodynamic Models in the Context of Environmental Risk Assessment. AB - Environmental risk assessment (ERA) of chemicals relies on the combination of exposure and effects assessment. Exposure concentrations are commonly estimated using mechanistic fate models, but the effects side is restricted to descriptive statistical treatment of toxicity data. Mechanistic effect models are gaining interest in a regulatory context, which has also sparked discussions on model quality and good modeling practice. Proposals for good modeling practice of effect models currently focus very much on population and community models, whereas effects models also exist at the individual level, falling into the category of toxicokinetic-toxicodynamic (TKTD) models. In contrast to the higher level models, TKTD models are usually completely parameterized by fitting them to experimental data. In fact, one of their explicit aims is to replace descriptive methods for data analysis. Furthermore, the construction of these models does not fit into an orderly modeling cycle, given that most TKTD models have been under continuous development for decades and are being applied by many different research groups, for many different purposes. These aspects have considerable consequences for the application of frameworks for model evaluation. For example, classical sensitivity analysis becomes rather meaningless when all model parameters are fitted to a data set. We illustrate these issues with the General Unified Threshold model for Survival (GUTS), relate them to the quality issues for currently used models in ERA, and provide recommendations for the evaluation of TKTD models and their analyses.

AB - Asymmetrically etched ion-track membranes attract great interest for both fundamental and technical reasons because of a large variety of applications. So far, conductometric measurements during track etching provide only limited information about the complicated asymmetric etching process. In this paper, monitoring of osmotic phenomena is used to elucidate the initial phase of nanopore formation. It is shown that strong alkaline solutions generate a considerable osmotic flow of water through newborn conical pores. The interplay between diffusion and convection in the pore channel results in a substantially nonlinear alkali concentration gradient and a rapid change in the pore geometry after breakthrough. Similar phenomena are observed in experiments with cylindrical track-etched pores of 15-30 nm in radius. A theoretical description of the diffusion-convection processes in the pores is provided.

AB - A method for creating nanoparticles directly from bulk metal by applying ultrasound to the surface in the presence of a two-part surfactant system is presented. Implosive collapse of cavitation bubbles near the bulk metal surface generates powerful microjets, leading to material ejection. This liberated material is captured and stabilized by a surfactant bilayer in the form of nanoparticles. The method is characterized in detail using gold, but is also demonstrated on other metals and alloys, and is generally applicable. It is shown that nanoparticles can be produced regardless of the bulk metal form factor, and the method is extended to an environmentally important problem, the reclamation of gold from an electronic waste stream.

AB - Exploring the ordering mechanism and dynamics of self-assembled block copolymer (BCP) thin films under confined conditions are highly essential in the application of BCP lithography. In this study, it is aimed to examine the self assembling mechanism and kinetics of silicon-containing 3-arm star-block copolymer composed of polystyrene (PS) and poly(dimethylsiloxane) blocks as nanostructured thin films with perpendicular cylinders and controlled lateral ordering by directed self-assembly using topographically patterned substrates. The ordering process of the star-block copolymer within fabricated topographic patterns with PS-functionalized sidewall can be carried out through the type of secondary (i.e., heterogeneous) nucleation for microphase separation initiated from the edge and/or corner of the topographic patterns, and directed to grow as well-ordered hexagonally packed perpendicular cylinders. The growth rate for the confined microphase separation is highly dependent upon the dimension and also the geometric texture of the preformed pattern. Fast self-assembly for ordering of BCP thin film can be achieved by lowering the confinement dimension and also increasing the concern number of the preformed pattern, providing a new strategy for the design of BCP lithography from the integration of top-down and bottom-up approaches.

When produced individually, PduA hexamers and PduB trimers, tessellate to form flat sheets in the crystal, or they can self-assemble to form synthetic protein nanotubes in solution. Modelling the orientation of PduA in the 20 nm nanotube so as to preserve the shape complementarity and key interactions seen in the crystal structure suggests that the concave surface of the PduA hexamer faces out. This orientation is confirmed experimentally in synthetic nanotubes and in the bacterial microcompartment produced in vivo. The PduB nanotubes described here have a larger diameter, 63 nm, with the concave surface of the trimer again facing out. The conserved concave surface out characteristic of these nano structures reveals a generic assembly process that causes the interface between adjacent subunits to bend in a common direction that optimizes shape complementarity and minimizes steric clashes. This understanding underpins engineering strategies for the biotechnological application of protein nanotubes.

AB - BACKGROUND: The Childhood Health Assessment Questionnaire (CHAQ) has been adapted from the Stanford Health Assessment Questionnaire for assessing functional ability in children. The present study aimed to determine the correlation between CHAQ and disease activity in juvenile idiopathic arthritis (JIA) during active and inactive disease. METHODS: JIA patients in the Pediatric Department, Ramathibodi Hospital, between January 2011 and December 2013, were included in the study. The CHAQ disability index (DI) and disease activity variables, including active and limited joint count, erythrocyte sedimentation rate, patient's global assessment (PtGA), physician's global assessment (PGA) and 27 joint Juvenile Arthritis Disease Activity Score (JADAS27), were collected from medical records for each patient over six visits. At each visit, each patient was classified as having either active or inactive disease. The correlations between CHAQ-DI and disease activity variables were analysed using Spearman's correlation. RESULTS: The classification of 139 JIA patients consisted of enthesitis-related arthritis (30.9%), systemic JIA (28.1%), oligoarthritis (16.5%), rheumatoid factor (RF)-negative polyarthritis (15.1%), RF-positive polyarthritis (6.5%) and undifferentiated arthritis (2.9%). Out of 812 patient visits, 606 were in active disease and 206 were in inactive disease. RF-negative polyarthritis had the highest CHAQ-DI (0.39 +/- 0.66), while oligoarthritis had the lowest (0.20 +/- 0.32). There was a good correlation between CHAQ-DI and JADAS27, PGA and PtGA in all JIA subtypes (p < 0.05) during active disease, but a poor correlation between CHAQ-DI and disease activity variables during inactive disease. CONCLUSIONS: CHAQ-DI had a good correlation with disease activity during active disease but a poor correlation during inactive disease. Therefore, CHAQ is only useful for assessing functional ability during active disease. PMID- 29573558 TI - Vascularization of the tumours affects the pharmacokinetics of bleomycin and the effectiveness of electrochemotherapy. AB - Pre-clinical and clinical data indicate differences in the responses of melanoma and carcinoma tumours to electrochemotherapy. The purpose of this study was to investigate the origin of this difference, whether it is due to the intrinsic difference in tumour cell susceptibility to the chemotherapeutic, or due to the tumour micro-environment. For this purpose, we performed a pre-clinical study in B16F1 melanoma and TS/A carcinoma tumours in mice, in which the antitumour effectiveness of electrochemotherapy with bleomycin, the intrinsic sensitivity of tumour cells in vitro, the pharmacokinetics of bleomycin in plasma and tumours, and the vascularization of tumours in vivo were evaluated. The results of the treatment show that carcinoma was significantly more responsive to electrochemotherapy than melanoma. This effect cannot be ascribed to the intrinsic sensitivity of these cells, as melanoma cells were more sensitive than carcinoma cells in vitro. The difference in responses could be ascribed to differences in the pharmacokinetics of bleomycin; at the time of electroporation in carcinomas, more bleomycin was accumulated. This effect could be due to differences in tumour vascularization, as carcinoma tumours had numerous well distributed, small blood vessels, while melanomas were less vascularized, exhibiting predominantly larger vessels. In conclusion, this study provides evidence on the importance of the tumour micro-environment, particularly the tumour vasculature, in the responses of the tumours to bleomycin electrochemotherapy. Vasculature is important for the pharmacokinetics of bleomycin, influencing drug accumulation and drug distribution in tumours, and might be used as a predictive factor for the tumour response to electrochemotherapy. PMID- 29573559 TI - Effectiveness of the national food supplementary program on children growth and nutritional status in Iran. AB - This study aimed to evaluate the effectiveness of the national food distribution program on the growth and nutritional status of malnourished or growth-retarded children in 2 provinces of Iran. A quasi-experimental design was used for the effectiveness evaluation. Qualitative data were gathered to explain the results. An intervention group consisted of 362 children aged 6-72 months who were under coverage of the program. These children received monthly food as foodstuff, food vouchers, or cash. A comparison group included 409 children aged 6-72 months who were selected from those covered by the Primary Health Care system. Children anthropometric indices were measured at the baseline and also 6 months later. Twelve focus group discussions were held with mothers who had at least 1 child under the coverage of the program. At the end of the study, the mean weight-for age Z scores, height-for-age Z scores, and weight-for-height Z scores increased compared with the baselines in both groups (p < .001). The differences between 2 groups in weight-for-age Z scores, height-for-age Z scores, and weight-for-height Z scores were not significant at the end of the study (p = .62, p = .91, and p = .94, respectively). According to the mothers' reports, factors affected the program outcome, that is, children anthropometric indices were low income, intrahousehold food sharing, irregular distribution, quantity and quality of the distributed food, and insufficient training. Providing foods for the malnourished children living in low-income families helped to prevent a worsening of their nutritional status; however, it has not been effective in solving the problem, probably due to the weak implementation and lack of empowerment strategies. PMID- 29573560 TI - Combination of blood and biphasic calcium phosphate microparticles for the reconstruction of large bone defects in dog: A pilot study. AB - We previously reported that biphasic calcium phosphate (BCP) microparticles embedded in a blood clot induces ectopic bone formation in mice and repairs a critical femoral defect in rat. The present pilot study aimed to evaluate in dog and in two models of large defects the efficacy of this composite named "blood for reconstruction of bone" (BRB). We show here that BRB is a cohesive biomaterial easy to prepare from dog autologous blood and to mold to fill large bone defects. First in a model of cylindrical femoral condyle defect, the BRB was compared with BCP particles alone. After 8 weeks, this revealed that the amount of mature bone was slightly and significantly higher with BRB than with BCP particles. Second, in a model consisting in a 2 cm-long critical interruptive defect of the ulna, the BRB was compared with autologous bone. After 6 months, we observed that implantation of BRB can induce the complete reconstruction of the defect and that newly formed bone exhibits high regenerative potential. Comparison with the results obtained with autologous bone grafting strongly suggests that the BRB might be an efficient biomaterial to repair large bone defects, as an alternative or in addition to autologous bone.

PMID- 29573561 TI - New care home admission following hospitalisation: How do older people, families and professionals make decisions about discharge destination? A case study narrative analysis. AB - AIMS AND OBJECTIVES: To gain an in-depth understanding of the decision-making processes involved in the discharge of older people admitted to hospital from home and discharged to a care home, as described in the case records. BACKGROUND: The decision for an older person to move into a care home is significant and life changing. The discharge planning literature for older people highlights the integral role of nurses in supporting and facilitating effective discharge. However, little research has been undertaken to explore the experiences of those discharged from hospital to a care home or the processes involved in decision making. METHOD: A purposive sample of 10 cases was selected from a cohort of 100 individuals admitted to hospital from home and discharged to a care home. Cases were selected to highlight important personal, relational and structural factors thought to affect the decision-making process. Narrative case studies were created and were thematically analysed to explore the perspectives of each stakeholder group and the conceptualisations of risk which influenced decision making. RESULTS: Care home discharge decision-making is a complex process involving stakeholders with a range of expertise, experience and perspectives. Decisions take time and considerable involvement of families and the multidisciplinary team. There were significant deficits in documentation which limit the understanding of the process and the patient's voice is often absent from case records. The experiences of older people, families and multidisciplinary team members making care home decisions in the hospital setting require further exploration to identify and define best practice. IMPLICATIONS FOR PRACTICE: Nurses have a critical role in the involvement of older people making discharge decisions in hospital, improved documentation of the patient's voice is essential. Health and social care systems must allow older people time to make significant decisions about their living arrangements, adapting to changing medical and social needs. PMID- 29573562 TI - Lived experiences of negative symptoms in first-episode psychosis: A qualitative secondary analysis. AB - AIM: Exploring how negative symptoms are experienced and understood by individuals with lived experience of psychosis has the potential to offer insights into the complex psychosocial processes underlying negative symptom presentations. The aim of the current study was to investigate lived experiences of negative symptoms through secondary analysis of interviews conducted with individuals recovering from first-episode psychosis. METHOD: Transcripts of in depth interviews with participants (n = 24) recruited from Early Intervention in Psychosis services were analysed thematically with a focus on participants' experiences and personal understandings of features corresponding to the negative symptoms construct. RESULTS: Descriptions of reductions in expression, motivation and sociability were common features of participants' accounts. Several participants described the experience of having difficulty interacting as like being a "zombie". Some participants experienced diminished capacity for emotion, thought or drive as underlying these experiences. However, participants typically attributed reductions in expression, motivation and sociability to medication side-effects, lack of confidence or active avoidance intended to protect them from rejection or ridicule, sometimes linked to internalized stigma. CONCLUSIONS: Personal accounts of experiences of reduced expression, motivation and sociability during first-episode psychosis highlight the personal meaningfulness and role of agency in these features, challenging the framing of negative symptoms as passive manifestations of diminished capacity. PMID- 29573564 TI - Multi-Anion Intercalated Layered Double Hydroxide Nanosheet-Assembled Hollow Nanoprisms with Improved Pseudocapacitive and Electrocatalytic Properties. AB - Electrochemically active hollow nanostructured materials hold great promise in diverse energy conversion and storage applications, however, intricate synthesis steps and poor control over compositions and morphologies have limited the realization of delicate hollow structures with advanced functional properties. In this study, we demonstrate a one-step wet-chemical strategy for co-engineering the hollow nanostructure and anion intercalation of nickel cobalt layered double hydroxide (NiCo-LDH) to attain highly electrochemical active energy conversion and storage functionalities. Self-templated pseudomorphic transformation of cobalt acetate hydroxide solid nanoprisms using nickel nitrate leads to the construction of well-defined NiCo-LDH hollow nanoprisms (HNPs) with multi-anion intercalation. The unique hierarchical nanosheet-assembled hollow structure and efficiently expanded interlayer spacing offer an increased surface area and exposure of active sites, reduced mass and charge transfer resistance, and enhanced stability of the materials. This leads to a significant improvement in the pseudocapacitive and electrocatalytic properties of NiCo-LDH HNP with respect to specific capacitance, rate and cycling performance, and OER overpotential, outperforming most of the recently reported NiCo-based materials. This work establishes the potential of manipulating sacrificial template transformation for the design and fabrication of novel classes of functional materials with well defined nanostructures for electrochemical applications and beyond. PMID- 29573563 TI - Quality-Quantity Control Culture Enhances Vasculogenesis and Wound Healing Efficacy of Human Diabetic Peripheral Blood CD34+ Cells. AB - Autologous endothelial progenitor cell (EPC) therapy is commonly used to stimulate angiogenesis in ischemic repair and wound healing. However, low total numbers and functional deficits of EPCs make autologous EPC therapy ineffective in diabetes. Currently, no known ex vivo culture techniques can expand and/or ameliorate the functional deficits of EPCs for clinical usage. Recently, we showed that a quality-quantity culture (QQc) system restores the vasculogenic and wound-healing efficacy of murine diabetic EPCs. To validate these results and elucidate the mechanism in a translational study, we evaluated the efficacy of this QQc system to restore the vasculogenic potential of diabetic human peripheral blood (PB) CD34+ cells. CD34+ cells purified from PB of diabetic and healthy patients were subjected to QQc. Gene expression, vascular regeneration, and expression of cytokines and paracrine mediators were analyzed. Pre- or post QQc diabetic human PB-CD34+ cells were transplanted into wounded BALB/c nude mice and streptozotocin-induced diabetic mice to assess functional efficacy. Post-QQc diabetic human PB-CD34+ cell therapy significantly accelerated wound closure, re epithelialization, and angiogenesis. The higher therapeutic efficacy of post-QQc diabetic human PB-CD34+ cells was attributed to increased differentiation ability of diabetic CD34+ cells, direct vasculogenesis, and enhanced expression of angiogenic factors and wound-healing genes. Thus, QQc can significantly enhance the therapeutic efficacy of human PB-CD34+ cells in diabetic wounds, overcoming the inherent limitation of autologous cell therapy in diabetic patients, and could be useful for treatment of not only wounds but also other ischemic diseases.

AB - AIM: Aboriginal young people are more likely to experience mental health issues and to access mental health services than other young Australians, yet there are few culturally informed mental health programs and services available. This study describes and documents the effectiveness of the culturally sensitive model within YouthLink, a state-wide mental health service program in Western Australia for young people aged 13 to 24 years of age. METHODS: A mixed-method design including a descriptive approach reporting on the YouthLink framework and an empirical research design where 40 Aboriginal clients completed client feedback monitoring measures between 2014 and 2016. RESULTS: The YouthLink culturally informed conceptual framework adheres to best practice principles relevant to work with Indigenous people, family and communities. Aboriginal young people indicated improvement across the treatment period as shown by within-group differences between the first and last session scores on feedback measures. Therapeutic alliance (together with lower baseline acuity and female gender) also contributed significantly to positive treatment outcomes. CONCLUSIONS: Through a strong role of Aboriginal practitioners, relationships with Aboriginal communities, and greater service flexibility that embraces cultural meaning and knowledge, YouthLink has sought to enhance its response to the needs of Aboriginal youth. PMID- 29573566 TI - Teaching paediatric transgender care. AB - BACKGROUND: We aimed to evaluate the effect of online modules - as stand-alone training - on paediatric transgender-related self-perceived knowledge, objective knowledge, and clinical self-efficacy of learners. We previously evaluated the online modules as part of a larger curriculum that included observation in a paediatric transgender clinic, and assessed change in self-perceived knowledge. METHODS: Paediatric interns, psychiatry interns, fourth-year medical students and nurse practitioner students were administered assessments before and after the completion of six online modules focused on medical and psychosocial considerations for transgender youth. The assessments queried learner demographics and transgender clinical exposure. Nine items tested transgender related objective knowledge. Twenty-four items asked learners to rate self perceived transgender-specific knowledge (1, not at all knowledgeable; 5, completely knowledgeable). Thirteen self-efficacy items asked learners to rate confidence in their ability to evaluate and counsel these youth (0, not at all confident; 10, completely confident). Overall and subscores were calculated for each domain. Wilcoxon signed-rank tests were used to compare the pre- and post module scores. RESULTS: Thirty-six learners were eligible to join the study and 86% (n = 31) participated. Among the participants, 90% (n = 28) completed both assessments. The median number of transgender patients seen before the curriculum was one, and 10% had past experience in a transgender clinic. Comparing pre- and post-module scores, the overall objective knowledge scores increased from 22 to 56% (p < 0.001), self-perceived knowledge scores increased from 1.8 to 3.8 (p < 0.001) and self-efficacy scores increased from 3.5 to 7.0 (p < 0.001). [What is] the effect of online modules on paediatric transgender-related self-perceived knowledge [?] DISCUSSION: This study suggests that e-learning was an effective stand-alone intervention to enhance transgender-related knowledge and self efficacy in interdisciplinary learners. PMID- 29573567 TI - Comparison of continuous-flow ventricular assist device therapy with intensive medical therapy in fixed pulmonary hypertension secondary to advanced left heart failure. AB - AIMS: Both ventricular assist device (VAD) and pulmonary vasodilator therapy have been shown in uncontrolled studies to improve pulmonary hypertension secondary to advanced left heart failure (Group 2 PH). This study aimed to compare haemodynamic benefits and survival in patients with fixed Group 2 PH treated with continuous-flow VAD to intensive medical therapy. METHODS AND RESULTS: Ninety five patients listed for heart transplantation with sequential right heart catheters were studied, 24 patients having fixed Group 2 PH (as defined by cardiac index < 2.8 L/min/m2 , pulmonary capillary wedge pressure > 15 mmHg, and transpulmonary gradient >= 15 mmHg or pulmonary vascular resistance > 3.0 WU, unresponsive to vasodilator challenge). Ten patients received VAD therapy, and 14 patients received standard heart failure therapy with or without sildenafil, nitrates, or endothelin receptor antagonists. At repeat right heart catheterization, patients treated with VAD therapy demonstrated significant improvement in both transpulmonary gradient (19 vs. 12 mmHg, P = 0.046) and pulmonary vascular resistance (6.5 vs. 2.9 WU, P = 0.003) compared with baseline, while those treated with medical therapy did not (20.9 vs. 20.3 mmHg and 6.5 vs. 6.4 WU, P = NS for both). Patients who received VAD therapy were significantly more likely to achieve normalized transpulmonary gradient (8/10 vs. 4/14, P = 0.013) and were more likely to be listed for orthotopic heart transplantation (7/10 vs. 4/14, P < 0.05). There were no significant differences between groups in terms of all-cause mortality. CONCLUSIONS: Continuous-flow VAD therapy more effectively reverses fixed Group 2 PH compared with medical therapy alone and may allow a higher rate of listing for orthotopic heart transplantation. PMID- 29573568 TI - Targeting LMW-PTP to sensitize melanoma cancer cells toward chemo- and radiotherapy. AB - Tumor resistance to apoptosis is one the main causes of anticancer treatment failure. Previous studies showed that LMW-PTP overexpression enhances resistance of cancer cells to traditional anticancer drugs. Today, the role of LMW-PTP in inducing resistance to apoptosis in melanoma cells remains to be elucidated. Experimental setting include MTT assay, Annexin V/Pi method, and colony assay to assess whether silencing of LMW-PTP improves the sensitivity of A375 to dacarbazine, 5-FU, and radiotherapy. Pharmacological targeting of LMW-PTP was obtained using Morin, a LMW-PTP inhibitor. The ability of Morin to improve the effectiveness of anticancer drugs and radiotherapy was also studied. Moreover, PC3 cells were used as an alternative cellular model to confirm the data obtained with melanoma cells. We found that LMW-PTP silencing improves the effectiveness of dacarbazine, 5-FU, and radiotherapy. Identical results were obtained in vivo when Morin was used to target LMW-PTP. We demonstrated that Morin synergizes with dacarbazine, improving its cytotoxic activity. However, we showed that the combined treatment, Morin-anticancer drug, does not affect the viability of noncancerous cells. Knockdown of LMW-PTP sensitizes also PC3 cells to docetaxel and radiotherapy. In conclusion, we showed that LMW-PTP targeting improves effectiveness of anticancer drugs used for treatment of melanoma. Moreover, our results suggest that Morin could be used as adjuvant to improve the outcome of patients affected by metastatic melanoma. PMID- 29573569 TI - Significant variations in the cervical cancer screening rate in China by individual-level and geographical measures of socioeconomic status: a multilevel model analysis of a nationally representative survey dataset. AB - Variations in cervical cancer screening rates in China have rarely been studied in depth. This study aimed to investigate cervical cancer screening rates in relation to both individual-level and geographical measures of socioeconomic status (SES). Data were obtained from women aged 21 years or older by face-to face interviews between August 2013 and July 2014 as part of the Chinese Chronic Diseases and Risk Factors Surveillance. The geographical variables were obtained from the 2010 Chinese population census. The cervical cancer screening rates and 95% confidence interval (CI) were estimated and mapped. Multilevel logistic regression models were fitted. Overall, only 21.4% (95% CI: 19.6-23.1%) of 91,816 women aged >=21 years reported having ever been screened for cervical cancer and significant geographical variations at both province and county levels were identified (P < 0.01). The cervical cancer screening rates were the lowest among the poor [13.9% (95% CI: 12.1-15.7%)], uninsured [14.4% (95% CI: 10.3-18.4%)], less-educated [16.0% (95% CI: 14.3-17.6%)], and agricultural employment [18.1% (95% CI: 15.8-20.4%)] women along with those residing in areas of low economic status [15.0% (95% CI: 11.8-18.2%)], of low urbanization [15.6% (95% CI: 13.4 17.7%)], and of low education status [16.0% (95% CI: 14.0-18.1%)]. The multilevel analysis also indicated that women with lower individual-level measures of SES residing in areas with low geographical measures of SES were significantly less likely to receive cervical cancer screening (P < 0.0001). Despite the launch of an organized cancer screening program in China, cervical cancer screening rates remain alarmingly low and significant variations based on geographical regions and measures of SES still exist. It is therefore essential to adopt strategies to better direct limited available public resources to priority groups. PMID- 29573571 TI - MoS2 Quantum Dots@TiO2 Nanotube Arrays: An Extended-Spectrum-Driven Photocatalyst for Solar Hydrogen Evolution. AB - TiO2 nanotube arrays (TiO2 NTAs) decorated with molybdenum disulfide quantum dots (MoS2 QDs) were synthesized by a facile electrodeposition method and used as a composite photocatalyst. MoS2 QDs/TiO2 NTAs showed enhanced photocatalytic activity compared with pristine TiO2 NTAs for solar light-promoted H2 evolution without adding any sacrificial agents or cocatalysts. The photocatalytic activity was influenced by the amount of MoS2 QDs coated on TiO2 NTAs. The optimal composition showed excellent photocatalytic activity, achieving H2 evolution rates of 31.36, 5.29, and 1.67 MUmol cm-2 h-1 corresponding to ultraviolet (UV, lambda<420 nm), visible (Vis, lambda>=420 nm), and near-infrared (NIR, lambda>760) illumination, respectively. The improved photocatalytic activity was attributed to the decreased bandgap and the surface plasmonic properties of MoS2 QDs/TiO2 NTAs, which promoted electron-hole pair separation and the absorption capacity for Vis and NIR light. This study presents a facile approach for fabricating MoS2 QDs/TiO2 NTA heterostructures for efficient photocatalytic H2 evolution, which will facilitate the development of designing new photocatalysts for environment and energy applications. PMID- 29573570 TI - A rapid and reliable chromosome analysis method for products of conception using interphase nuclei. AB - BACKGROUND: Karyotype determination has a central role in the genetic workup of pregnancy loss, as aneuploidy (trisomy and monosomy) and polyploidy (triploidy and tetraploidy) are the cause in at least 50% of first trimester, 25% of second trimester, and 11% of third trimester miscarriages. There are several limitations with the current approaches of obtaining a karyotype using traditional cytogenetics, fluorescence in situ hybridization with a limited number of probes, and chromosomal microarray. These include culture failure, incomplete results, lower sensitivity, and longer reporting time. METHODS: To overcome current limitations, a novel molecular assay is developed with a Standard Resolution Interphase Chromosome Profiling probe set which is a variation of the recently developed High Resolution probe set. It generates a molecular karyotype that can detect all major changes commonly associated with pregnancy loss. Initial familiarization of signal patterns from the probe set was used, followed by validation of the method using 83 samples from miscarriages in a blind study from three different laboratories. Finally, the clinical utility of the method was tested on 291 clinical samples in two commercial reference laboratory settings on two different continents. RESULTS: The new molecular approach not only identified all the chromosome changes observed by current methods, but also significantly improved abnormality detection by characterizing derivative chromosomes and finding subtle subtelomeric rearrangements, balanced and unbalanced. All Robertsonian translocations were also detected. The abnormality rate was 54% on clinical samples from commercial laboratory 1 and 63% from laboratory 2. CONCLUSION: The attributes of this method make it an ideal choice for the genetic workup of miscarriages, namely (1) near 100% successful results, (2) greater sensitivity than conventional chromosome analysis or FISH panels, (3) rapid reporting time, and (4) favorable comparisons with chromosomal microarray. PMID- 29573572 TI - General practice tasters for foundation doctors. AB - BACKGROUND: General practice (GP) is currently not viewed positively as a career choice, compared with other specialties, with GP training programmes struggling to fill posts. Opportunities to change this mindset in the early years of training are limited. Trainees may find themselves applying for entry into GP specialty training just 3-4 months after completing Foundation Year 1 (FY1), yet there are few GP attachments during FY1 that can provide experience of primary care and positively inform career choice. CONTEXT: To help ameliorate the current crisis in GP, recruitment and retention initiatives are needed to provide relevant experience of GP early in medical careers so that more doctors can make an informed decision to choose GP as a career. INNOVATION: FY1 doctors have been given the opportunity to shadow final-year GP specialty trainees (GPST3) in clinical practice (for between 3 and 5 days). The voluntary scheme has run successfully since 2014. This paper describes the taster programme and its evaluation. The programme has been positively received by both FY1s and GPST3 mentors. The GPST3s are enthusiastic about GP, which appeared to 'rub off' on the FY1s. FY1s find it helpful to have a trainee's perspective, gaining an overview of what to expect, including the opportunities available to them. General practice is currently not viewed positively as a career choice IMPLICATIONS: Using GPST3 trainees as mentors for FY1 doctors is educational for both groups and can have a positive impact on GP recruitment. The taster demonstrated how varied GP is, and challenged some negative perceptions of primary care. GPST3s gained confidence in their knowledge about GP and greater insight into educational roles. PMID- 29573573 TI - Chiral Metal-Organic Framework Hollow Nanospheres for High-Efficiency Enantiomer Separation. AB - Chiral ZIF-8 hollow nanospheres with d-histidine as part of chiral ligands (denoted as H-d-his-ZIF-8) were prepared for separation of (+/-)-amine acids. Compared to bulk d-his-ZIF-8 without a hollow cavity, the prepared H-d-his-ZIF-8 showed 15 times higher separation capacity and higher ee values of 90.5 % for alanine, 95.2 % for glutamic acid and 92.6 % for lysine, respectively. PMID- 29573574 TI - Prognostic significance of the infiltration of CD163+ macrophages combined with CD66b+ neutrophils in gastric cancer. AB - The polarization of tumor-associated macrophages (TAMs) and tumor-associated neutrophils (TANs), especially from the antitumoral phenotype to the protumoral phenotype under certain conditions, has an important influence on the progression of tumors. However, the interactions and combined prognosis of these cells are poorly known. Here, we detected the infiltration of CD68+ TAMs, CD163+ TAMs, and CD66b+ TANs in the specimens from 662 patients with GC by immunohistochemistry. The results showed that the infiltration of each of CD163+ , CD68+ , and CD66b+ cells in GC tissue was significantly increased and independently associated with GC prognosis. Strong collinearity (r = 0.690, P < 0.001) was found between the infiltration of CD163+ and CD68+ cells in GC, and multivariate Cox analysis confirmed the infiltration of CD163+ cells was a better predictor for prognosis than that of CD68+ cells. The combination of the infiltration of CD163+ and CD66b+ cells provided more accurate survival prediction than any individual marker. Patient subgroups with CD66blow CD163low (hazard ratio (HR) = 2.161; 95% confidence interval (CI) = 1.266-3.688; P < 0.001), CD66bhigh CD163high (HR = 3.575; 95% CI = 2.155-5.933; P < 0.001), and CD66blow CD163high (HR = 7.514; 95% CI = 4.583-12.312; P < 0.001) were gradually associated with shorter DFS when compared with the subgroup with CD66bhigh CD163low . The similar result was also for DSS among the subgroups. Moreover, the two-marker model could more effectively discriminate the prognosis among the patients with chemotherapy than that among those without chemotherapy. We concluded that CD163+ TAMs were a more valuable prognostic marker than CD68+ TAMs, and CD163+ TAMs combined with CD66b+ TANs could more precisely predict the prognosis of patients with GC. PMID- 29573575 TI - Heart rate response and functional capacity in patients with chronic heart failure with preserved ejection fraction. AB - AIMS: The mechanisms of exercise intolerance in heart failure with preserved ejection fraction (HFpEF) are not yet elucidated. Chronotropic incompetence has emerged as a potential mechanism. We aimed to evaluate whether heart rate (HR) response to exercise is associated to functional capacity in patients with symptomatic HFpEF. METHODS AND RESULTS: We prospectively studied 74 HFpEF patients [35.1% New York Heart Association Class III, 53% female, age (mean +/- standard deviation) 72.5 +/- 9.1 years, and 59.5% atrial fibrillation]. Functional performance was assessed by peak oxygen consumption (peak VO2 ). The mean (standard deviation) peak VO2 was 10 +/- 2.8 mL/min/kg. The following chronotropic parameters were calculated: Delta-HR (HR at peak exercise - HR at rest), chronotropic index (CI) = (HR at peak exercise - resting HR)/[(220 - age) resting HR], and CI according to the equation developed by Keteyian et al. (CIK) (HR at peak exercise - HR at rest)/[119 + (HR at rest/2) - (age/2) - 5 - HR at rest]. In a bivariate setting, peak VO2 was positively and significantly correlated with Delta-HR (r = 0.35, P = 0.003), CI (r = 0.27, P = 0.022), CIK (r = 0.28, P = 0.018), and borderline with HR at peak exercise (r = 0.22, P = 0.055). In a multivariable linear regression analysis that included clinical, analytical, echocardiographic, and functional capacity covariates, the chronotropic parameters were positively associated with peak VO2 . We found a linear relationship between Delta-HR and peak VO2 (beta coefficient of 0.03; 95% confidence interval: 0.004-0.05; P = 0.030); conversely, the association among CIs and peak VO2 was exponentially shaped. CONCLUSIONS: In patients with chronic HFpEF, the HR response to exercise was positively associated to patient's functional capacity. PMID- 29573576 TI - Toward clinical and molecular understanding of pathogenic variants in the ZBTB18 gene. AB - BACKGROUND: Patients with pathogenic variants in ZBTB18 present with Intellectual Disability (ID) with frequent co-occurrence of corpus callosum (CC) anomalies, hypotonia, microcephaly, growth problems and variable facial dysmorphologies. These features illustrate a key role for ZBTB18 in brain development. METHODS: Patients with a pathogenic variant in ZBTB18 were detected by diagnostic whole exome sequencing (WES) performed in our center. We reviewed the literature and used GeneMatcher to include other cases. YASARA and WHAT IF were used to provide insight into the structural effect of missense variants located in the C2H2 zinc finger domains of the ZBTB18 protein. RESULTS: We give a complete overview of pathogenic variants in ZBTB18 detected to date, showing inconsistent presence of clinical features, including CC anomalies. We present four new cases with a de novo pathogenic variant in the ZBTB18 gene, including the fourth case in which a de novo p.Arg464His variant was found. CONCLUSION: Homology modeling of protein structure points to a variable degree of impaired DNA binding caused by missense variants in these domains probably leading to Loss of Function (LoF). Putative partial LoF may present with a less distinctive phenotype than complete LoF, as seen in truncating variants, which presents with an extensive variability in the phenotypic spectrum. Our data do not support a clear genotype to phenotype correlation.

AB - INTRODUCTION: Cytogenetically normal acute myeloid leukemia (CN-AML), which accounted for nearly half of total AML patients, is a highly heterogeneous subset of AML. The specific genetic profile and the ethnic features of CN-AML are worth to be studied. METHODS: Using deep sequencing technology, we detected the mutation pattern of 39 genes in 152 Chinese CN-AML patients and analyzed their clinical features. RESULTS: A total of 503 mutations of 39 genes were identified in 145 (95.4%) patients, with the median number of 3 mutations per case. Nine genes (NPM1, CEBPA, DNMT3A, GATA2, NRAS, TET2, FLT3, IDH2, and WT1) mutated in more than 10% patients. Function groups of myeloid transcription factors, activated signaling, and DNA methylation were most affected. The distribution of variant allele frequencies (VAF) of recurrent genes was different among functional groups. High mutation rates of CEBPA and GATA2 together with the low frequency of FLT3-ITD mutation seemed to be the distinct characteristics of Chinese patients. Furthermore, CEBPAbi and GATA2 were found to mutate most in M2 subtype, while NPM1 and DNMT3A mutated more in M4 and M5. The prognostic analysis identified CEBPAmo mutation as an inferior factor. FLT3-ITD, TP53, DNMT3A, CEBPAmo, and WT1 mutations were selected as high-risk markers to identify the CN AML patients with poor prognosis. CONCLUSION: Our study provided the valuable information of ethnic genetic characteristics and the clinical relevance of Chinese CN-AML patients. PMID- 29573578 TI - Associations of sleep duration and prediabetes prevalence in a middle-aged and elderly Chinese population with regard to age and hypertension: The China Health and Retirement Longitudinal Study baseline survey. AB - BACKGROUND: The aim of the present study was to examine the age-specific associations between self-reported sleep duration and prevalent prediabetes in middle-aged and elderly Chinese with or without hypertension. METHODS: In all, 2985 Chinese adults aged >=45 years from the China Health and Retirement Longitudinal Study (CHARLS) baseline survey were selected for analysis. Sleep duration was assessed by structured questionnaires and then categorized into three groups (<=6, 6-8, and >8 h). The prevalence of prediabetes was defined using fasting plasma glucose (100-125 mg/dL) and/or HbA1c (5.7%-6.4%) in conjunction with no previous diabetes diagnosis and no antidiabetic medication. Relationships between self-reported sleep duration and prevalent prediabetes were examined according to age (45-60 years, middle-aged; >=60 years, elderly) and hypertension groups using Poisson regression models to estimate prevalence ratios (PRs) and 95% confidence intervals (CI). RESULTS: Compared with the reference group of 6-8 h sleep/night, short sleep (<=6 h/night) was associated with an increased risk of prediabetes in the whole sample (PR 1.09, 95% CI 1.01-1.17) after adjusting for confounders. This association was more pronounced in elderly participants without hypertension (PR 1.27, 95% CI 1.07-1.51). CONCLUSION: This study suggests that participants with a short sleep period are at a moderately increased risk of prediabetes, particularly in elderly subjects without hypertension. Aging and hypertension may be important in the relationship between short sleep and impaired glucose metabolism. PMID- 29573579 TI - Infundibulum of the common origin of fourth lumbar arteries and median sacral artery. AB - We describe an infundibulum of a common origin of the fourth lumbar arteries and the median sacral artery. To the best of our knowledge there has been no such published case thus far and its natural course is unknown, in view of its novelty. Infundibular dilatations in intracranial arteries have been described to progress in size and potentially rupture. Therefore, we recommended follow-up imaging, as part of the management, to ensure stability of the infundibulum. PMID- 29573580 TI - Boosting ORR Catalytic Activity by Integrating Pyridine-N Dopants, a High Degree of Graphitization, and Hierarchical Pores into a MOF-Derived N-Doped Carbon in a Tandem Synthesis. AB - N-doped carbon materials represent promising metal-free electrocatalysts for the oxygen reduction reaction (ORR), the cathode reaction in fuel cells, metal-air batteries, and so on. A challenge for optimizing the ORR catalytic activities of these electrocatalysts is to tune their local structures and chemical compositions in a rational and controlled way that can achieve the synergistic function of each factor. Herein, we report a tandem synthetic strategy that integrates multiple contributing factors into an N-doped carbon. With an N containing MOF (ZIF-8) as the precursor, carbonization at higher temperatures leads to a higher degree of graphitization. Subsequent NH3 etching of this highly graphitic carbon enabled the introduction of a higher content of pyridine-N sites and higher porosity. By optimizing these three factors, the resultant carbon materials displayed ORR activity that was far superior to that of carbon derived from a one-step pyrolysis. The onset potential of 0.955 V versus a reversible hydrogen electrode (RHE) and the half-wave potential of 0.835 V versus RHE are among the top ranks of metal-free ORR catalysts and are comparable to commercial Pt/C (20 wt %) catalysts. Kinetic studies revealed lower H2 O2 yields, higher electron-transfer numbers, and lower Tafel slopes for these carbon materials compared with that derived from a one-step carbonization. These findings verify the effectiveness of this tandem synthetic strategy to enhance the ORR activity of N-doped carbon materials. PMID- 29573581 TI - Automatic segmentation of pigment deposits in retinal fundus images of Retinitis Pigmentosa. AB - Retinitis Pigmentosa is an eye disease that presents with a slow loss of vision and then evolves until blindness results. The automatic detection of the early signs of retinitis pigmentosa acts as a great support to ophthalmologists in the diagnosis and monitoring of the disease in order to slow down the degenerative process. A large body of literature is devoted to the analysis of Retinitis Pigmentosa. However, all the existing approaches work on Optical Coherence Tomography (OCT) data, while hardly any attempts have been made working on fundus images. Fundus image analysis is a suitable tool in daily practice for an early detection of retinal diseases and the monitoring of their progression. Moreover, the fundus camera represents a low-cost and easy-access diagnostic system, which can be employed in resource-limited regions and countries. The fundus images of a patient suffering from retinitis pigmentosa are characterized by an attenuation of the vessels, a waxy disc pallor and the presence of pigment deposits. Considering that several methods have been proposed for the analysis of retinal vessels and the optic disk, this work focuses on the automatic segmentation of the pigment deposits in the fundus images. The image distortions are attenuated by applying a local pre-processing. Next, a watershed transformation is carried out to produce homogeneous regions. Working on regions rather than on pixels makes the method very robust to the high variability of pigment deposits in terms of color and shape, so allowing the detection even of small pigment deposits. The regions undergo a feature extraction procedure, so that a region classification process is performed by means of an outlier detection analysis and a rule set. The experiments have been performed on a dataset of images of patients suffering from retinitis pigmentosa. Although the images present a high variability in terms of color and illumination, the method provides a good performance in terms of sensitivity, specificity, accuracy and the F-measure, whose values are 74.43, 98.44, 97.90, 59.04, respectively. PMID- 29573582 TI - Deformable respiratory motion correction for hepatic rotational angiography. AB - Cone-beam rotational angiography enables 3D imaging of the hepatic vasculature and is considered beneficial for guidance of transcatheter arterial chemoembolization procedures. Respiratory motion during the rotational acquisition challenges state-of-the-art reconstruction algorithms as intra-scan motion leads to inconsistencies causing substantial blurring and streaking artifacts in uncompensated reconstructions, suggesting the need for motion correction. We propose an automated method for respiratory motion estimation and compensation based on registration of an initial 3D arterial model to vesselness enhanced 2D projection images. Centerline points of the arterial tree are modeled as B-splines over time, the control point positions of which are optimized using alpha-expansion moves on graph cuts. This approach naturally allows for the estimation of 3D rigid translations as well as non-rigid deformations. Applied to a pre-clinical and a clinical acquisition, the proposed methods resulted in notable reductions in reprojection error and increased vessel sharpness that are reflected in less streaking and blurring artifact compared to the uncompensated case, implying superior vessel contrast. As the proposed methods are generic, future work will investigate their applicability to related rotational angiography imaging protocols, such as coronary angiography. PMID- 29573583 TI - An application of cascaded 3D fully convolutional networks for medical image segmentation. AB - Recent advances in 3D fully convolutional networks (FCN) have made it feasible to produce dense voxel-wise predictions of volumetric images. In this work, we show that a multi-class 3D FCN trained on manually labeled CT scans of several anatomical structures (ranging from the large organs to thin vessels) can achieve competitive segmentation results, while avoiding the need for handcrafting features or training class-specific models. To this end, we propose a two-stage, coarse-to-fine approach that will first use a 3D FCN to roughly define a candidate region, which will then be used as input to a second 3D FCN. This reduces the number of voxels the second FCN has to classify to ~10% and allows it to focus on more detailed segmentation of the organs and vessels. We utilize training and validation sets consisting of 331 clinical CT images and test our models on a completely unseen data collection acquired at a different hospital that includes 150 CT scans, targeting three anatomical organs (liver, spleen, and pancreas). In challenging organs such as the pancreas, our cascaded approach improves the mean Dice score from 68.5 to 82.2%, achieving the highest reported average score on this dataset. We compare with a 2D FCN method on a separate dataset of 240 CT scans with 18 classes and achieve a significantly higher performance in small organs and vessels. Furthermore, we explore fine-tuning our models to different datasets. Our experiments illustrate the promise and robustness of current 3D FCN based semantic segmentation of medical images, achieving state-of-the-art results.1.

AB - Lactococcus lactis is the most widely utilised starter bacterial species in dairy fermentations. The L. lactis cell envelope contains polysaccharides, which, among other known functions, serve as bacteriophage receptors. Our previous studies have highlighted the structural diversity of these so-called cell wall polysaccharides (CWPSs) among L. lactis strains that could account for the narrow host range of most lactococcal bacteriophages. In the present work, we studied the CWPS of L. lactis strain UC509.9, an Irish dairy starter strain that is host to the temperate and well-characterized P335-type phage Tuc2009. The UC509.9 CWPS structure was analyzed by methylation, deacetylation/deamination, Smith degradation and 2D NMR spectroscopy. The CWPS consists of a linear backbone composed of a tetrasaccharide repeat unit, partially substituted with a branched phosphorylated oligosaccharide having a common trisaccharide and three non stoichiometric substitutions. PMID- 29573585 TI - Synthesis of bidesmosidic lupane saponins - comparison of batch and continuous flow methodologies. AB - Synthesis of lupane bidesmosides was optimized. The title compounds were obtained by glycosylation of 3-O- or 28-O-substituted betulin monodesmosides with Schmidt donors catalyzed by TMSOTf. Classical batch procedure and microreactor technique were used and compared in the above synthesis. Experimental results clearly showed that both methods are comparable, although any particular outcome strongly depends on the structure of the reagents. Undesired allobetulin derivatives formed by the Wagner-Meerwein rearrangement were usually isolated in minute amounts. In the case of batch reaction, shorter reaction time significantly decreased formation of side-products. PMID- 29573586 TI - Decreased interleukin-11 levels in the semen of infertile males. AB - The relationship between the interleukin (IL)-11 levels and semen quality of infertile males remains unknown. In this study, 120 semen samples from 60 normozoospermic volunteers and 60 infertile males were examined. The semen pH of the normozoospermic group was not significantly different from that of the infertile group. The semen volume, semen density, forward movement percentage, activity, survival rate and normal morphology rate of the sperm of the infertile group were significantly lower than those of the normozoospermic group. The semen IL-11 levels of the infertile group were significantly lower than those of the normozoospermic group. In the infertile group, semen IL-11 levels were positively correlated with sperm motility, vitality, survival rate and normal sperm morphology rate and negatively correlated with IL-17 and IL-18 levels. Therefore, semen IL-11 levels could be used as an index of male infertility. PMID- 29573587 TI - The study of wood knots using acoustic nondestructive testing methods. AB - In the process of wood grading with the focus on detecting wood knots, nondestructive testing methods based on sound transmission can assist the traditional characterization methods to achieve a higher efficiency and better results. In this paper, we use two independent methods based on resonance and sound speed measurements to evaluate the elastic modulus of wood beams containing different knots. The results show that the method based on sound speed measurements offers a fast procedure to evaluate whether the knot is in the middle of the cross-section of the beam or not. In this case, both measuring methods are reliable in determining the knot's characteristics. In the off-center case, the resonance method performs better to quantify the size of the knots. PMID- 29573588 TI - Virtual nondestructive evaluation for anisotropic plates using Symmetry Informed Sequential Mapping of Anisotropic Green's function (SISMAG). AB - In this article, a generalized computational method to simulate virtual nondestructive evaluation (NDE) of anisotropic composite plates is presented. The ultrasonic wave fields were computed using a modified and generalized version of Distributed Point Source Method (DPSM), a semi-analytical mesh-free technique. The anisotropic Green's functions required for DPSM implementation were calculated using Fourier transform method and Radon transform method and compared. It is established that the Green's functions obtained from two different methods are identical. Applying generalized mathematical formulations, NDE of different degrees of anisotropic: transversely isotropic, orthotropic and monoclinic material are simulated and reported in this article. To boost the computational efficiency, a Symmetry Informed Sequential Mapping of Anisotropic Green's function (SISMAG) is introduced with DPSM and discussed in detail. To prove the above claims, virtual NDE experiments of anisotropic plates with normal and angle incidence of the ultrasonic wave are simulated using a circular transducer of central frequency ~1 MHz. Wave fields inside both the fluid and the solid media were calculated. PMID- 29573589 TI - Whole organism to tissue concentration ratios derived from an Australian tropical dataset. AB - Whole organism to tissue concentration ratios (CRwo-tissue) were derived for six wildlife groups (freshwater birds, freshwater bivalves, freshwater fishes, freshwater reptiles, freshwater vascular plants and terrestrial mammals). The wildlife groups and data represented species common to tropical northern Australia. Values of CRwo-tissue were derived for between 6 and 34 elements, depending upon wildlife group. The values were generally similar to international reference values. However, differences for some element-tissue combinations could affect radiation dose estimates for wildlife in certain environmental exposure situations, including uranium mining, where these data are intended to be applied. PMID- 29573590 TI - Numerical modeling of the sources and behaviors of 222Rn, 220Rn and their progenies in the indoor environment-A review. AB - 222Rn, 220Rn and their short-lived progenies are well known radioactive indoor pollutants, identified as the leading environmental cause of lung cancer next to smoking. Apart from the conventional measurement methods, numerical modeling methods are developed to simulate their physical and decay processes in 222Rn and 220Rn's life cycle, estimate their levels, concentration distributions, as well as effects of control strategies in the indoor environment. In this article, we summarized the numerical models used to illustrate the physical processes of each source of 222Rn and 220Rn entry into the indoor environment, and the application of Jacobi room models and CFD (Computational Fluid Dynamic) models used to present the behaviors of indoor 222Rn, 220Rn and their progenies. Furthermore, we consider that the development of numerical modeling of 222Rn and 220Rn would have a bright prospect in the directions of stochastic methods based on a steady-state model, the fine simulation of the time-dependent model as well as the multi dimension model. PMID- 29573591 TI - Facilitation of an end-of-life care programme into practice within UK nursing care homes: A mixed-methods study. AB - BACKGROUND: The predicted demographic changes internationally have implications for the nature of care that older people receive and place of care as they age. Healthcare policy now promotes the implementation of end-of-life care interventions to improve care delivery within different settings. The Gold Standards Framework in Care Homes (GSFCH) programme is one end-of-life care initiative recommended by the English Department of Health. Only a small number of care homes that start the programme complete it, which raises questions about the implementation process. AIM: To identify the type, role, impact and cost of facilitation when implementing the GSFCH programme into nursing care home practice. DESIGN: A mixed-methods study. SETTING: Nursing care homes in south east England. PARTICIPANTS: Staff from 38 nursing care homes undertaking the GSFCH programme. Staff in 24 nursing care homes received high facilitation. Of those, 12 also received action learning. The remaining 14 nursing care homes received usual local facilitation of the GSFCH programme. METHODS: Study data were collected from staff employed within nursing care homes (home managers and GSFCH coordinators) and external facilitators associated with the homes. Data collection included interviews, surveys and facilitator activity logs. Following separate quantitative (descriptive statistics) and qualitative (template) data analysis the data sets were integrated by 'following a thread'. This paper reports study data in relation to facilitation. RESULTS: Three facilitation approaches were provided to nursing home staff when implementing the GSFCH programme: 'fitting it in' facilitation; 'as requested' facilitation; and 'being present' facilitation. 'Being present' facilitation most effectively enabled the completion of the programme, through to accreditation. However, it was not sufficient to just be present. Without mastery and commitment, from all participants, including the external facilitator, learning and initiation of change failed to occur. Implementation of the programme required an external facilitator who could mediate multi-layered learning at an individual, organisational and appreciative system level. The cost savings in the study outweighed the cost of providing a 'being present' approach to facilitation. CONCLUSIONS: Different types of facilitation are offered to support the implementation of end-of-life care initiatives. However, in this study 'being present' facilitation, when supported by multi-layered learning, was the only approach that initiated the change required. PMID- 29573592 TI - How older adults and their informal carers prevent falls: An integrative review of the literature. AB - : Falls in older persons are prevalent and costly for the individual and the health system. Falls prevention guidelines have been developed from best evidence to minimise falls in older persons. AIM: To synthesise the literature on falls prevention strategies used by community dwelling older persons and/or their informal carers and to compare the commonly adopted strategies with those recommended by falls prevention guidelines. DATA SOURCES: Health sciences databases for full text articles published in English plus reference list searching of included articles. REVIEW METHOD: An integrative review approach. Studies were included if they identified fall prevention management strategies used by community dwelling older adults and/or their informal carers. Quality appraisal was undertaken using appropriate Joanna Briggs Institute critical appraisal tools. Information relevant to the aim of the review were extracted and coded into categories then inductively sorted into sub-themes and themes. RESULTS: Of the seventeen studies included in the review, eleven identified older adults' falls prevention strategies, two investigated fall prevention strategies used by carers, and four explored perspectives of older persons together with their carers, representing the perspectives of an estimated 501 older persons and 102 carers. Strategies used by older adults arose because of self-awareness about their changing physical ability, and advice and support mainly from family or friends. Carer fall prevention strategy was predominantly around protection of the older adult from falling by discouraging independence. CONCLUSIONS: The fall self-management strategies adopted by older adults and their carers to prevent falls, in the main, do not align with international best practice fall prevention guidelines. PMID- 29573593 TI - The evidence base for psychological interventions for rheumatoid arthritis: A systematic review of reviews. AB - BACKGROUND: Psychological interventions are an important but often overlooked adjunctive treatment option for patients with rheumatoid arthritis. Findings from systematic reviews of psychological interventions for this patient group are conflicting. A systematic review of reviews can explain inconsistencies between studies and provide a clearer understanding of the effects of interventions. OBJECTIVES: To: 1) determine the effectiveness of psychological interventions in improving biopsychosocial outcomes for adults with rheumatoid arthritis, 2) determine the relationship between the intensity of the psychological interventions (number of sessions, duration of sessions, duration of intervention) on outcomes, and 3) assess the impact of comparator group (usual care, education only) on outcomes. DESIGN: We conducted a systematic review of reviews using the following inclusion criteria: 1) randomised controlled trials of psychological interventions (including cognitive behavioural therapy, supportive counselling, psychotherapy, self-regulatory techniques, mindfulness based cognitive therapy and disclosure therapy) provided as an adjunct to medication, 2) included rheumatoid arthritis patients aged >= 18 years, 3) reported findings for at least 1 of the primary outcomes: pain, fatigue, psychological status, functional disability and disease activity and 4) were published in English between January 2000 and March 2015 (updated January 2018). DATA SOURCES: We searched in MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. Reference lists were searched for additional reviews. REVIEW METHODS: Study selection and 50% of the quality assessments were performed by two independent reviewers. Methodological quality was measured using the Assessment of Multiple Systematic Reviews checklist. Data extraction was conducted by one reviewer using a predesigned data extraction form. RESULTS: Eight systematic reviews met inclusion criteria (one review was excluded due to its low-quality score). Small post intervention improvements in patient global assessment, functional disability, pain, fatigue, anxiety and depression were observed. The effect on coping, self-efficacy and physical activity was greater. Improvements in depression, coping and physical activity were maintained (8.5-14 months). Interventions delivered over a longer period with a maintenance component appeared more effective. Attention, education, and placebo control groups produced some improvements but not as large as those produced by the psychological interventions. CONCLUSIONS: Psychological interventions result in small to moderate improvements in biopsychosocial outcomes for patients with rheumatoid arthritis in addition to those achieved by standard care. Several priorities for future research were identified, including determining the cost effectiveness of non-psychologically trained health professionals delivering psychological interventions. PMID- 29573594 TI - Looking but not seeing: Increased eye fixations in behavioural-variant frontotemporal dementia. AB - Face processing plays a central role in human communication, with the eye region a particularly important cue for discriminating emotions. Indeed, reduced attention to the eyes has been argued to underlie social deficits in a number of clinical populations. Despite well-established impairments in facial affect recognition in behavioural-variant frontotemporal dementia, whether these patients also have perturbed facial scanning is yet to be investigated. The current study employed eye tracking to record visual scanning of faces in 20 behavioural-variant frontotemporal dementia patients and 21 controls. Remarkably, behavioural-variant frontotemporal dementia patients displayed more fixations to the eyes of emotional faces, compared to controls. Neural regions associated with fixations to the eyes included the left inferior frontal gyrus, right cerebellum and middle temporal gyrus. Our study is the first to show such compensatory functions in behavioural-variant frontotemporal dementia and suggest a feedback style network, including anterior and posterior brain regions, is involved in early face processing. PMID- 29573595 TI - Post-traumatic stress and relationships to coping and alexithymia in patients with psychogenic non-epileptic seizures. AB - PURPOSE: There is increasing evidence that patients with PNES can form subgroups distinguished by emotion dysregulation and comorbid psychological symptoms. The purpose of this study was to determine if patients with comorbid PTSD differ from other patients with PNES in terms of alexithymia and stress coping strategies. METHODS: 156 adult patients with video-EEG confirmed PNES were assessed with the Trauma Symptom Inventory-2 (TSI-2) and diagnostic clinical interview, Toronto Alexithymia Scale (TAS-20), and the Coping Inventory for Stressful Situations (CISS). There were 3 groups: 48 patients with PTSD, 62 patients who had experienced trauma and did not have PTSD, and 46 patients who denied experiencing trauma. RESULTS: One-way ANCOVA revealed a significant difference between groups on reported levels of alexithymia [F(2, 154) = 18.21, p < .001] and use of emotion-focused coping [F(2, 156) = 11.12, p < .001]. Tukey HSD post-hoc comparisons indicated that the PNES/PTSD group had significantly higher mean alexithymia scores (M = 59.54, SD = 12.89) than both the no trauma (M = 49.51, SD = 14.92) and the trauma with no PTSD groups (M = 49.98, SD = 13.27), which did not differ from each other. The PNES/PTSD group was also significantly more likely (M = 62.44, SD = 11.56) than the no trauma (M = 52.87, SD = 13.57) and the trauma with no PTSD groups (M = 52.06, SD = 12.63) to utilize emotion-focused coping strategies. No significant differences were found between groups on use of task- or avoidance-focused coping. CONCLUSION: The study revealed elevated alexithymia and use of potentially more maladaptive emotion-focused coping strategies among patients with PNES and comorbid PTSD. These findings highlight discrete areas to target in treatment depending on comorbid symptomatology, and suggests that PNES, which is often regarded as a homogeneous entity, appears to encompass distinct subgroups. PMID- 29573596 TI - Lemierre's syndrome following perianal abscess: A case report. AB - INTRODUCTION: Lemierre's syndrome (LS) is a rare and life-threatening condition characterized by suppurative thrombophlebitis of the internal jugular vein (IJV), and a history of head and neck (H&N) sepsis. LS is usually caused by Fusobacterium necrophorum, which is part of the normal flora in the oro-pharynx, and the digestive and urogenital tracts. We here report the first case of LS following perianal sepsis. PRESENTATION OF CASE: A 60-year-old man with a painful left neck swelling, dysphagia and worsening sepsis was referred from a peripheral unit where he had an incision and drainage of a perianal abscess a week earlier. Urgent Doppler ultrasound and computed tomographic scans demonstrated suppurative thrombophlebitis of the left IJV, and the patient was subsequently commenced on intravenous Piperacillin/Tazobactam and heparin. The symptoms gradually improved, and the patient was eventually discharged on the 10th day. DISCUSSION: Vigilant examination of the H&N region searching for a primary source is paramount, but LS following infections in the gastrointestinal or uro-genital tracts has also been described. A high index of suspicion is required for diagnosis, especially in patients with unresolving pharyngitis with a unilateral neck swelling, and septicaemia. Early resuscitation and treatment with broad-spectrum parenteral antimicrobials are important for favourable outcome. CONCLUSION: LS is well known to specialists in the H&N region, but other disciplines like general surgery, urology, or obstetrics and gynaecology might also rarely encounter the disease. We present a case of LS complicating a perianal abscess that was successfully treated with good outcome. PMID- 29573597 TI - Laparoscopic Roux-en-Y gastric bypass in a patient with situs inversus totalis: Case report, technical tips and review of the literature. AB - INTRODUCTION: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has proven over the years to be one of the most effective bariatric procedures. It is highly technical, and therefore is mostly performed by bariatric and metabolic surgeons. Although Situs Inversus Totalis (SIT) is a very rare congenital condition, surgeons do occasionally have to operate intra-abdominally on those patients, consequently facing some challenges related to the unusual anatomy. CASE PRESENTATION: We describe a rare case of LRYGB for chronic morbid obesity on a 43 year old patient with pre-operative diagnosis of situs inversus totalis without Kartagener's syndrome, using slight modification from the usual technique based on anatomical correlation without the need to change the surgeon's position or switching trocar placements as described in previous papers. This could help surgeons in general reduce the potential challenges faced when performing such procedure. CONCLUSION: Situs Inversus Totalis is a rare congenital condition, but surgeons in general do encounter those patients throughout their career. This rare condition should not solely be an indication for an open approach as minimally invasive surgery, whether laparoscopic or robotic, is safe and should still be considered the standard of care approach. Bariatric surgery is one of the most technical intra-abdominal procedures mainly due to the patients' body habitus, different instrumentations used, and the different anastomoses created. Gastric bypass and bariatric surgery in general can be safely performed on patients with SIT without the need for major adjustment to the surgeon's position, trocar placement or instruments used. PMID- 29573598 TI - Clinical value of 11C-methionine positron emission tomography in persistent primary hyperparathyroidism-A case report with a mediastinal parathyroid adenoma. AB - INTRODUCTION: Primary hyperparathyroidism (PHPT) is a common endocrine disorder caused by pathologic growth of one or more of the parathyroid glands. Parathyroidectomies (PTX) in patients with PHPT are procedures with low morbidity, few complications, and a high cure rate. However, the parathyroid glands may be found at various anatomical locations and occasionally they are intrathoracic. CASE PRESENTATION: We present a 57-year-old patient with PHPT. Before the first and second operation, the preoperative imaging indicated pathologic parathyroid tissue in the neck. Due to postoperative persistent hypercalcemia we performed a 11C-methionine positron emission tomography (11C-MET PET/CT). The scan showed a focus with increased activity in the mediastinum. Due to persistent disease, an ectopic parathyroid gland in the mediastinum was suspected. At a third operation, the parathyroid adenoma was resected through an anterolateral thoracotomy. Biochemical values normalized and bone mineral density improved postoperatively. Hence, an ectopic localization of a parathyroid gland should be considered during the preoperative planning of a PTX, especially in the re-operative setting. A multidisciplinary effort is necessary to address an intrathoracic adenoma. CONCLUSION: Ectopic parathyroid glands should be suspected when positive sestaMIBI uptake is seen in the mediastinum and other types of imaging (e.g. contrast enhanced CT scan or PET-CT) may confirm the finding of an ectopic parathyroid adenoma. From the present case and previous studies we found 11C-MET-PET/CT valuable in difficult PHPT cases. PMID- 29573599 TI - Perforation of abdominal esophagus following nasogastric feeding tube intubation: A case report. AB - INTRODUCTION: Perforation of the abdominal esophagus caused by nasogastric tube (NGT) intubation has been rarely reported in adults. PRESENTATION OF CASE: A 73 year-old man was admitted to our hospital with pneumonia. He had been bedridden long-term and had previously undergone a gastrectomy for gastric ulcer. Since admission was prolonged, and he required enteral feeding because of his inability to swallow, a NGT was inserted blindly. The next day, he had a high fever and abdominal pain. Abdominal computed tomography scan revealed that the tube was inserted through the wall of the abdominal esophagus into the abdominal cavity. In the emergency surgery, we sutured the perforated site of abdominal esophagus and patched it with lesser omentum. The postoperative course was good. DISCUSSION: Abdominal esophageal perforation due to NGT insertion is very rare. The cause of perforation was suggested to be an abnormal deformity created by adhesion due to previous distal gastrectomy and long-term bedridden status. A chest X-ray usually is performed to confirm the position of the NGT tube. In this case, a frontal radiographic view apparently showed the NGT placed in the stomach. CONCLUSION: When NGT is inserted to such patients, frontal and lateral radiographic views or fluoroscopic guidance should be obtained.

AB - INTRODUCTION: Angiolipomas are benign, slow growing lesions, almost always located subcutaneously in the trunc or limbs. They are composed of mature lipocytes admixed with abnormal blood vessels. Spinal epidural angiolipoma are rare accounting for approximately 0.14-1.2% of all spinal axis tumors and 2-3% of epidural spinal tumors. PRESENTATION OF CASE: We report the case of a 65 years old-woman, presenting with complete paraplegia installed since 7 months. Magnetic resonance imaging (MRI) showed an epidural dorsal fatty mass. The patient recovered immediately after surgery. The pathological examination concluded to an angiolipoma. DISCUSSION: Angiolipoma patients most commonly have long-lasting pain and then develop progressive neurological symptoms secondary to spinal cord compression. The mean duration of symptom progression at diagnosis is 1 year. MRI is the most reliable examination for the diagnosis of spinal angiolipoma. Total resection is the treatment of choice. No adjuvant treatment is indicated. Since SAL are very haemorrhagic lesions, preoperative embolization is recommended. CONCLUSION: We think that spinal cord compression caused by angiolipoma have very good functional prognosis, even if tardily diagnosed.

AB - INTRODUCTION: Assessments of the impact of road traffic injuries (RTIs) on quality of life (QoL) can benefit from the use of combined characteristics of the injurious event. AIM: The burden of having sustained a RTI was computed using a composite score that comprised three elements (i.e. number of injuries sustained in the crash, body parts affected, and severity of the injuries) that relate to the probability of subsequent long-term QoL lost by individuals 1-4 years after the crash. METHODOLOGY: The QoL of injured victims aged 11-90 years that crashed in Sweden between 2007 and 2009 was compared with that of a random sample of non injured individuals frequency-matched by sex and age. Injury information to build the composite score was obtained from a national register that contains data on the number of injuries, their severity, and the body parts affected. The QoL was assessed in 2010 for both injured and non-injured individuals using the standardized Euro Quality of Life questionnaire. Logistic regression was used to investigate whether the composite score was predictive of low QoL (<90% of the mean of non-injured referents) adjusting for sex, age, and time elapsed since the injury occurrence. The composite score was grouped into five exposure categories (0.01-1, 1.01-1.5, 1.51-2, 2.01-3 and 3.01-9 units). RESULTS: Compared with the non-injured reference group, all exposure categories showed statistically significant increased adjusted ORs for low QoL ranging from 2.35 (95% CI 1.48 3.72) in the 0.01-1.00 lowest injury category to 6.10 (95% CI 3.65-10.2) in the highest 3.01-9.00 with a slightly decreasing plateau in the intermediate categories (point ORs between 3.86 and 3.06). Yet, all 95% CIs across the exposure categories overlapped. CONCLUSION: Long-term reduction in QoL is a burden experienced by the victims of mild to severe RTCs. The proposed composite score can be an initial step in the development of more elaborated instruments that can be useful in policy making and regulation.

AB - INTRODUCTION: Numerous quantitative studies have examined the association between family meal frequency and child/adolescent weight and weight-related behaviors. However, limited qualitative research has been conducted to identify mealtime characteristics (e.g., child behavior during meals, rules/expectations, family dynamics) that occur during family meals that may explain why some families engage in frequent family meals and others do not. This is particularly important within racially/ethnically diverse households, as these demographic groups are at higher risk for weight-related problems. The current study aimed to identify similarities and differences in mealtime characteristics between households that have frequent and infrequent family meals within a low-income and minority population. METHODS: This qualitative study included 118 parents who participated in Family Meals, LIVE!, a mixed-methods, cross-sectional study. Parents (90% female; mean age = 35) were racially/ethnically diverse (62% African American, 19% White, 4% Native American, 4% Asian, 11% Mixed/Other) and from low-income (73% < $35,000/yr.) households. Data were analyzed using inductive content analysis. RESULTS: Results indicated some similar mealtime characteristics (i.e., picky eating, involving family members in meal preparation) between households having frequent and infrequent family meals. Additionally, several differences in mealtime characteristics were identified between households having frequent (i.e., importance of family meals, flexibility in the definition of family meals, family meal rules, no pressure-to-eat feeding practices) versus infrequent family meals (i.e., pressure-to-eat parent feeding practices, family meals are dinner meals only, and difficult meal time behaviors). DISCUSSION: Study findings may be useful for developing intervention targets for low-income and racially/ethnically diverse households so more families can benefit from the protective nature of family meals.

AB - Toxicological effects of sulfamethazine (SM2) have garnered increasing concern due to its wide applications in aquaculture and persistence in the aquatic environment. Most studies have main focused on freshwater fish (i.e. zebrafish), while information regarding effects of SM2 on marine species is still scarce. Here, the hepatotoxicities in marine medaka (Oryzias melastigma) with an increasing SM2 concentration exposures (0.01 mg/L, 0.1 mg/L and 1 mg/L) were assessed by comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC * GC-TOF/MS) based metabolomics. Significant metabolites belonging to different metabolites classes were identified by multivariate statistical analysis. The increases levels of amino acids including alanine, asparagine, ornithine, proline, threonine, glutamic acid, lysine, tyrosine and phenylalanine were found in at least two exposure levels. Pathway analysis revealed that amino acids played important biological roles during SM2 exposure: up-regulation of high energy-related amino acids for energy alteration; immune function disorder, oxidative stress and corresponding toxicities defenses. The down regulations of sugar and fatty acid metabolism were observed with an increasing level of SM2 exposure, suggesting that extra energy for cellular defense and detoxification was demanded in terms of different stress request. This study provided an innovative perspective to explore possible SM2 induced hepatic damages at three exposure levels on a nontarget aquatic specie.

AB - PURPOSE: Early prediction of acute kidney injury (AKI) in septic patients is difficult. This study aimed to assess the values of renal resistive index (RI), central venous pressure (CVP), and their combination in the early prediction of sepsis-induced AKI. METHODS: A prospective cohort study was performed in septic patients. The variables potentially associated with AKI were recorded at admission and compared between the AKI and non-AKI groups. The variables independently associated with sepsis-induced AKI were identified using multivariable logistic regression, and the area under the receiver operating characteristic curve (AUROC) analysis was calculated. RESULTS: A total of 124 septic patients were included. Septic shock (OR, 3.28; P=0.002), high CVP (OR, 1.92; P=0.012) and renal RI (OR, 2.58; P=0.009), low diastolic perfusion pressure (DPP) (OR, 2.15; P=0.010) at admission were independent risk factors for sepsis induced AKI. The AUROC value of the combination of RI and CVP was greater compared with either RI or CVP alone in predicting sepsis-induced AKI (AUROC=0.858, 0.811, and 0.780, respectively). CONCLUSIONS: The combination of RI and CVP was more valuable than either of the two parameters in the early prediction for sepsis-induced AKI.

AB - In order to implement X-chromosome short tandem repeat (X-STR) typing into routine forensic practice, reference database of a given population should be established. Therefore we extended already published data with additional 397 blood samples from unrelated Croatian citizens, and analyzed the total of 995 samples (549 male and 446 female) typed by Investigator(r) Argus X-12 Kit. To test genetic homogeneity of consecutively processed five historic-cultural regions covering the entire national territory, we calculated pairwise Fst genetic distances between regions based on allele and full haplotype frequencies. Since the comparison did not yield any statistically significant difference, we integrated STR profile information from all regions and used the whole data set to calculate forensic parameters. The most informative marker is DXS10135 (polymorphism information content (PIC = 0.929) and the most informative linkage group (LG) is LG1 (PIC = 0.996). We confirmed linkage disequilibrium (LD) for seven marker pairs belonging to LG2, LG3 and LG4. By including LD information, we calculated cumulative power of discrimination that amounted to 0.999999999997 in females and 0.999999005 in males. We also compared Croatia with 13 European populations based on haplotype frequencies and detected no statistically significant Fst values after Bonferroni correction in any LG. Multi-dimensional scaling plot revealed tight grouping of four Croatian regions amongst populations of southern, central and northern Europe, with the exception of northern Croatia. In this study we gave the first extensive overview of aberrant profiles encountered during Investigator(r) Argus X-12 typing. We found ten profiles consistent with single locus duplication followed by tetranucleotide tract length polymorphism. Locus DXS10079 is by far the most frequently affected one, presumably mutated in eight samples. We also found four profiles consistent with X-chromosome aneuploidy (three profiles with XXX pattern and one profile with XXY pattern). In conclusion, we established integral forensic Croatian X-chromosome database, proved forensic pertinence of Investigator(r) Argus X-12 Kit for the entire Croatian population and identified locus DXS10079 as a potential duplication hotspot. PMID- 29573606 TI - Repair of DNA damage caused by cytosine deamination in mitochondrial DNA of forensic case samples. AB - DNA sequence damage from cytosine deamination is well documented in degraded samples, such as those from ancient and forensic contexts. This study examined the effect of a DNA repair treatment on mitochondrial DNA (mtDNA) from aged and degraded skeletal samples. DNA extracts from 21 non-probative, degraded skeletal samples (aged 50-70 years) were utilized for the analysis. A portion of each sample extract was subjected to DNA repair using a commercial repair kit, the New England BioLabs' NEBNext FFPE DNA Repair Kit (Ipswich, MA). MtDNA was enriched using PCR and targeted capture in a side-by-side experiment of untreated and repaired DNA. Sequencing was performed using both traditional (Sanger-type; STS) and next-generation sequencing (NGS) methods Although cytosine deamination was evident in the mtDNA sequence data, the observed level of damaged bases varied by sequencing method as well as by enrichment type. The STS PCR amplicon data did not show evidence of cytosine deamination that could be distinguished from background signal in either the untreated or repaired sample set. However, the same PCR amplicons showed 850 C -> T/G -> A substitutions consistent with cytosine deamination with variant frequencies (VFs) of up to 25% when sequenced using NGS methods The occurrence of base misincorporation due to cytosine deamination was reduced by 98% (to 10) in the NGS amplicon data after repair. The NGS capture data indicated low levels (1-2%) of cytosine deamination in mtDNA fragments that was effectively mitigated by DNA repair. The observed difference in the level of cytosine deamination between the PCR and capture enrichment methods can be attributed to the greater propensity for stochastic effects from the PCR enrichment technique employed (e.g., low template input, increased PCR cycles). Altogether these results indicate that DNA repair may be required when sequencing PCR-amplified DNA from degraded forensic case samples with NGS methods. PMID- 29573608 TI - Thermal decomposition and kinetics of coal and fermented cornstalk using thermogravimetric analysis. AB - The thermal behavior and kinetics of Yiluo coal (YC) and the residues of fermented cornstalk (FC) were investigated in this study. The Kissinger-Akahira Sunose (KAS) and Flynn-Wall-Ozawa (FWO) methods were used for the kinetic analysis of the pyrolysis process. The results showed that the activation energy (Ealpha) was increased with the increase of the thermal conversion rate (alpha), and the average values of Ealpha of YC, FC and the blend (mYC/mFC = 6/4) were 304.26, 224.94 and 233.46 kJ/mol, respectively. The order reaction model function for the blend was also developed by the master-plots method. By comparing the Ea and the enthalpy, it was found that the blend was favored to format activated complex due to the lower potential energy barrier. Meanwhile, the average value of Gibbs free energy of the blend was 169.83 kJ/mol, and the changes of entropies indicated that the pyrolysis process was evolved from ordered-state to disordered state. PMID- 29573607 TI - Substrates removal and growth kinetic characteristics of a heterotrophic nitrifying-aerobic denitrifying bacterium, Acinetobacter harbinensis HITLi7T at 2 degrees C. AB - In order to investigate the heterotrophic nitrification and aerobic denitrification ability of Acinetobacter harbinensis HITLi7T at 2 degrees C, both the growth parameters and substrates utilization characteristics were tested and appropriated kinetic models were obtained in this study. Under the initial concentration of 5 mg/L, the maximum NH4+-N and NO3--N degradation rates were 0.076 mg NH4+-N/L/h and 0.029 mg NO3--N/L/h, respectively. At the simultaneous presence of 2.5 mg/L NH4+-N and NO3--N, the maximum nitrate removal rate increased to 0.054 mg NO3--N/L/h (1.86 folds), while a slight decrease was observed in NH4+-N removal. Two double-substrate models, Contois-Contois (1) for NH4+-N and TOC, Monod-Contois (2) for NO3--N and TOC matched well with the experimental data. The kinetic parameters were determined as MUmax1 = 0.095 h-1, BA1 = 0.012 mg/L, BT1 = 0.784 g TOC/g biomass (R12 = 0.9997), and MUmax2 = 0.032 h-1, KN2 = 0.375 mg/L, BT2 = 1.108 g TOC/g biomass (R22 = 0.9731) by multiple regression equation. PMID- 29573609 TI - Specific enrichment of hyperthermophilic electroactive Archaea from deep-sea hydrothermal vent on electrically conductive support. AB - While more and more investigations are done to study hyperthermophilic exoelectrogenic communities from environments, none have been performed yet on deep-sea hydrothermal vent. Samples of black smoker chimney from Rainbow site on the Atlantic mid-oceanic ridge have been harvested for enriching exoelectrogens in microbial electrolysis cells under hyperthermophilic (80 degrees C) condition. Two enrichments were performed in a BioElectrochemical System specially designed: one from direct inoculation of crushed chimney and the other one from inoculation of a pre-cultivation on iron (III) oxide. In both experiments, a current production was observed from 2.4 A/m2 to 5.8 A/m2 with a set anode potential of -0.110 V vs Ag/AgCl. Taxonomic affiliation of the exoelectrogen communities obtained on the electrode exhibited a specific enrichment of Archaea belonging to Thermococcales and Archeoglobales orders, even when both inocula were dominated by Bacteria.

AB - In order to improve the adsorption capacities of corncob-based biochars for heavy metal, the different pyrolysis temperature (350 degrees C, 450 degrees C and 550 degrees C) of corncob-based biochars were modified with the acrylonitrile, and adsorption capacities of Cadmium from solution by biochars were studied. The results showed that only at 350 degrees C the biochar can be successfully modified. The Cd adsorption capacity (85.65 mg/g) by the biosorbent was higher than other methods of modifying biochars previously reported. SEM-EDS and FTIR confirmed that the CN group was grafted on the biochar at low pyrolysis temperature. Batch adsorption experiment including pH-dependence, adsorption kinetics, and isotherms and XPS results showed that the removal mechanism of Cd(II) by the modified biochar was ion exchange and adsorption-complexation. This research not only obtained a novel method to modify biochar but also furthered research into the lignin of biochar composition, and provided an efficient sorbent for heavy metal. PMID- 29573611 TI - Kinetic analysis of curdlan production by Alcaligenes faecalis with maltose, sucrose, glucose and fructose as carbon sources. AB - Curdlan has wide-ranging benefits in food and pharmaceutical industries for its unique rheological and thermal gelling properties. To analyze the cell growth and curdlan biosynthesis kinetics of Alcaligenes faecalis, the kinetic properties of the curdlan fermentation under different carbon sources conditions (maltose, sucrose, glucose and fructose) were investigated using Logistic and Luedeking Piret equations. The results demonstrated that curdlan fermentation is partial growth-associated process. With maltose as the sole carbon source, the highest curdlan production (Pm = 39.3 g/L), the maximum specific growth rate (MUm = 0.44/h) and the growth-associated rate constant (alpha = 2.05 g curdlan/g cell) were achieved. In contrast, the fructose was the less desired carbon source in both the cell growth and curdlan production. Further, the results demonstrated that slow-releasing glucose from maltose boosted cell growth and curdlan production. PMID- 29573612 TI - Isolation of new cellulase and xylanase producing strains and application to lignocellulosic biomasses hydrolysis and succinic acid production. AB - The enzymatic extracellular mixtures of two new microorganisms - Streptomyces flavogriseus AE64X and AE63X - isolated from Eucalyptus camaldulensis and Populus nigra and producing cellulase and xylanase, were characterized and applied to hydrolysis of pretreated Arundo donax, Populus nigra and Panicum virgatum (10% w/v) replacing the commercial enzymes Accelerase 1500 and Accelerase XY (5.4 and 145 U/g of pretreated biomass, respectively). It is worth of noting that the newly developed extracellular enzymatic mixtures, without any purification step and at the same dosage, presented saccharification yields that are higher (86% for S. flavogriseus AE64X) than those of commercial enzymes (81%). Moreover, these enzymatic mixes allowed us to hydrolyse both cellulose and xylan within the different lignocellulose biomasses substituting both the cellulase and xylanase of commercial source. The produced sugars were also fermentable by Basfia succiniciproducens BPP7 into succinic acid with high yield. PMID- 29573613 TI - Improvement of cadmium phytoremediation by Centella asiatica L. after soil inoculation with cadmium-resistant Enterobacter sp. FM-1. AB - This study examined the potential of a cadmium-resistant Enterobacter sp. FM-1 to promote plant growth and assist in cadmium accumulation in both mine-type C. asiatica L. and non-mine type C. asiatica L. tissues in highly cadmium-polluted soils. The results indicated that Enterobacter sp. FM-1 significantly promoted growth and alleviated metal toxicity in both types of C. asiatica L. Meanwhile, inoculation with Enterobacter sp. FM-1 in contaminated soil can increased cadmium bioavailability in soil. Furthermore, it will increase plant uptake and the accumulation of cadmium in C. asiatica L. leaves, stems and roots compared to that in an uninoculated plant. However, mine-type C. asiatica L. had better cadmium tolerance than the non mine-type C. asiatica L. Because of its native metal-tolerant ability, which could easily grow and proliferate, and had a better performance under cadmium-contamination conditions. Additionally, inoculation with Enterobacter sp. FM-1 significantly enhanced the bioaccumulation factor (BAF) and the translocation factor (TF) values in both types of C. asiatica L. even under high cadmium concentration soil condition. Hence, based on higher BAF and TF values and strong cadmium accumulation in the leaves and stems, we concluded that inoculation with Enterobacter sp. FM-1 is potentially useful for the phytoremediation of cadmium-contaminated sites by Centella asiatica L. PMID- 29573614 TI - Effects of glyphosate and its commercial formulation, Roundup(r) Ultramax, on liver histology of tadpoles of the neotropical frog, Leptodactylus latrans (amphibia: Anura). AB - In the last years, the agricultural expansion has led to an increased use of pesticides, with glyphosate as the most widely used worldwide. This is also the situation in Argentina, where glyphosate formulations are the most commercialized herbicides. It is known that glyphosate formulations are much more toxic than the active ingredient, and this difference in toxicity can be attributed to the adjuvants present in the formula. In this context, the aim of the present study was to evaluate and compare sub-lethal histological effects of the glyphosate formulation Roundup Ultramax and glyphosate active ingredient on Leptodactylus latrans tadpoles at Gosner-stage 36. Semi-static bioassays were performed using 96 h of exposure with Roundup Ultramax formulation (RU; 0.37-5.25 mg a.e./L), glyphosate (GLY; 3-300 mg/L), and a control group. RU exposure showed an increment in the melanomacrophagic cells (MMc) and melanomacrophagic centers (MMCs) from 0.37 mg a.e./L. GLY exposure showed a significant increment in the number of MMc from 15 mg/L, and of MMCs from 3 mg/L. Also, histopathological lesions were observed in the liver of tadpoles exposed to both, GLY and RU. These lesions included: lipidosis and hepatic congestion, but only RU showed significant differences respect to control, with a LOEC value of 2.22 mg a.e./L for both effects. In sum, this study represents the first evidence of adverse effects of glyphosate and RU formulation on the liver of anuran larvae at concentrations frequently found in the environment. PMID- 29573615 TI - The preparation of carboxylic-functional carbon-based nanofibers for the removal of cationic pollutants. AB - A simple route is presented to fabricate carboxylic-functional carbon-coated polyacrylonitrile nanofibers (oPAN@C) through preoxidation and hydrothermal carbonization. PAN fibers were firstly preoxidized to form aromatic ladder structure with the resistance to hydrothermal condition, in which more carboxyl groups were introduced on the fiber surface at the present of chitosan and citric acid. The oPAN@C composites exhibit a high adsorption capacity towards methylene blue (MB) and lead ion (Pb2+). The adsorption data matched the pseudo-second order kinetic model and Langmuir model well with the maximum adsorption capacity (153.37 and 143.27 mg g-1) for methylene blue and Pb2+, respectively. Moreover, oPAN@C could be regenerated easily by hydrochloric acid, and still remained high removal efficiency after 5 cycles. Therefore, oPAN@C fibers should have potential application in sewage treatment. PMID- 29573616 TI - Changes in microbial communities during volatile fatty acid production from cyanobacterial biomass harvested from a cyanobacterial bloom in a river. AB - Volatile fatty acid (VFA) production, utilization of soluble organic compounds, and associated microbial consortia were investigated after different pretreatments (untreated, alkaline, and thermal-alkaline) using cyanobacterial biomass as a substrate. Compared to the untreated control, soluble carbohydrate concentrations were almost the same after alkaline and thermal-alkaline pretreatments, but soluble protein concentration was 1.58 times higher after alkaline pretreatment and 1.81 times higher after thermal-alkaline pretreatment. However, the highest degree of acidification was obtained after alkaline pretreatment (55.36 +/- 3.00%). Microbial communities in the untreated control differed only slightly from those after thermal-alkaline pretreatment, but were clearly distinct from those after alkaline pretreatment. After alkaline pretreatment, protein-utilizing bacteria became relatively predominant. These results revealed the relationships between efficiency of VFA production and the shift in microbial community. PMID- 29573617 TI - Anti-arrhythmogenic and anti-inflammatory effects of troxerutin in ischemia/reperfusion injury of diabetic myocardium. AB - INTRODUCTION: Medicinal plants are increasingly used in the treatment of cardiovascular diseases due to their multifaceted properties. This study was designed to investigate anti-arrhythmic and anti-inflammatory potentials of the natural bioflavonoid, troxerutin (TXR) in myocardial ischemia/reperfusion (I/R) injury in diabetic rats. METHODS: Male Wistar rats were randomly divided into 4 groups (control, control + TXR [150 mg/kg, daily], diabetic, and diabetic + TXR). Type-1 diabetes was induced by an intraperitoneal injection of streptozotocin (50 mg/kg) and lasted for 10 weeks. After mounting on the Langendorff apparatus, isolated hearts in all groups received a normal Krebs-Henseleit solution for 20 min of stabilization period, followed by 30 min of regional ischemia through ligation of the left anterior descending coronary artery, and 60 min of full reperfusion. During the experiment, the electrocardiograms were recorded and the arrhythmias [number, duration and incidence of premature ventricular complexes (PVC), ventricular tachycardia (VT), ventricular fibrillation (VF), and arrhythmia score] during I/R phases were assessed based on the Lambeth Convention. Ischemic left ventricular samples were used to determine the activities of lactate dehydrogenase (LDH), interleukin-1beta (IL-1beta), and tumor necrosis factor (TNF-alpha). RESULTS: The arrhythmias induced by I/R were not significantly changed in diabetic group as compared to the control group. However, pretreatment with TXR significantly reduced the number of PVC and duration and incidence of VF in ischemic phase in comparison to the untreated animals (P < 0.05). In addition, the duration, and incidence of most arrhythmias during reperfusion phase were significantly declined by TXR administration in both control and diabetic groups (P < 0.05). Pretreatment of rats with TXR significantly reduced myocardial inflammatory cytokines TNF-alpha and IL-1beta levels after I/R insult in diabetic as well as control hearts (P < 0.05). CONCLUSION: Preconditioning with TXR could provide cardioprotection by anti arrhythmic and anti-inflammatory effects against I/R injury in rat hearts. This effect of TXR can introduce this material as a protective agent in cardiovascular diseases. PMID- 29573618 TI - Umbelliferone prevents oxidative stress, inflammation and hematological alterations, and modulates glutamate-nitric oxide-cGMP signaling in hyperammonemic rats. AB - Hepatic encephalopathy (HE) is a serious neuropsychiatric complication that occurs as a result of liver failure. Umbelliferone (UMB; 7-hydroxycoumarin) is a natural product with proven hepatoprotective activity; however, nothing has yet been reported on its protective effect against hyperammonemia, the main culprit behind the symptoms of HE. Here, we evaluated the effect of UMB against ammonium chloride (NH4Cl)-induced hyperammonemia, oxidative stress, inflammation and hematological alterations in rats. We demonstrated the modulatory role of UMB on the glutamate-nitric oxide (NO)-cGMP pathways in the cerebrum of rats. Rats received intraperitoneal injections of NH4Cl (3 times/week) for 8 weeks and concomitantly received 50 mg/kg UMB. NH4Cl-induced rats showed significantly elevated blood ammonia and liver function markers. Lipid peroxidation and NO were increased in the liver and cerebrum of rats while the antioxidant defenses were declined. UMB significantly reduced blood ammonia, liver function markers, lipid peroxidation and NO, and enhanced the antioxidant defenses in NH4Cl-induced rats. UMB significantly prevented anemia, leukocytosis, thrombocytopenia and prolongation of PT and aPTT. Hyperammonemic rats showed elevated levels of cerebral TNF-alpha, IL-1beta and glutamine as well as increased activity and expression of Na+/K+-ATPase, effects that were significantly reversed by UMB. In addition, UMB down-regulated nitric oxide synthase and soluble guanylate cyclase in the cerebrum of hyperammonemic rats. In conclusion, this study provides evidence that UMB protects against hyperammonemia via attenuation of oxidative stress and inflammation. UMB prevents hyperammonemia associated hematological alterations and therefore represents a promising protective agent against the deleterious effects of excess ammonia. PMID- 29573619 TI - Estrogen: The necessary evil for human health, and ways to tame it. AB - Estrogen is a pivotal enzyme for survival and health in both genders, though their quantum, tropism, tissue-specific distribution, and receptor affinity varies with different phases of life. Converted from androgen via aromatase enzyme, this hormone is indispensable to glucose homeostasis, immune robustness, bone health, cardiovascular health, fertility, and neural functions. However, estrogen is at the center of almost all human pathologies as well-infectious, autoimmune, metabolic to degenerative. Both hypo and hyper level of estrogen has been linked to chronic and acute diseases. While normal aging is supposed to lower its level, leading to tissue degeneration (bone, muscle, neural etc.), and metabolite imbalance (glucose, lipid etc.), the increment in inflammatory agents in day-to-day life are enhancing the estrogen (or estrogen mimic) level, fueling 'estrogen dominance'. The resultant excess estrogen is inducing an overexpression of estrogen receptors (ERalpha and ERbeta), harming tissues, leading to autoimmune diseases, and neoplasms. The unprecedented escalation in the polycystic ovary syndrome, infertility, breast cancer, ovary cancer, and gynecomastia cases are indicating that this sensitive hormone is getting exacerbated. This critical review is an effort to analyze the dual, and opposing facets of estrogen, via understanding its crosstalk with other hormones, enzymes, metabolites, and drugs. Why estrogen level correction is no trivial task, and how it can be restored to normalcy by a disciplined lifestyle with wise dietary and selective chemical usage choices has been discussed. Overall, our current state of knowledge does not disclose the full picture of estrogen's pleiotropic importance. Hence, this review should be a resource for general public as well as researchers to work in that direction. PMID- 29573620 TI - Sesquiterpenoids from the root of Panax Ginseng protect CCl4-induced acute liver injury by anti-inflammatory and anti-oxidative capabilities in mice. AB - The oxidative stress and inflammatory response play an important role in carbon tetracholoride (CCl4)-induced acute liver injury. In this work, sesquiterpenoids from the root of Panax Ginseng (SPG) were prepared, and then the hepatoprotective effects of SPG against CCl4-induced acute liver injury were investigated and the underlying mechanism was explored in mice. All mice were divided into four groups: the control, CCl4 and SPG (2.5 and 10 mg/kg, dissolved in soybean oil, i.g.) groups. All mice were given continuous administration for 7 days, and injected with CCl4 (0.1 mL/10 g body weight 0.2% CCl4 solution in soybean oil, i.p.) 1 h after the end of the administration except the control group. Mice were sacrificed 24 h post-CCl4 injection. The results indicated that SPG significantly reduced the increasement of serum AST and ALT levels induced by CCl4-treatment. And the histopathological analysis revealed that SPG treated mice had normal liver architecture and no necrosis. The decreased activities of SOD, GSH and CAT, and increased MDA level were inhibited by SPG treatment. At the same time, the levels of TNF-alpha, IL-1beta and IL-6 were significantly decreased by SPG treatment. SPG treatment also reduced the heptic protein expressions of NF-kappaB p65, COX-2, MAPK p38, ERK and JNK in the liver. These fingdings demonstrated that SPG exhibited strong hepatoprective effect on the CCl4-induced acute liver injury, which was related to anti-oxidantive and anti-inflammatory capabilities; and the anti-inflammatory effect of SPG might mediated by the NF-kappaB and MAPKs signaling pathways. Taken together, SPG might be a potential material for drug and functional food development against chemical hepatic injury. PMID- 29573621 TI - Photoelectrochemical TiO2 nanotube arrays biosensor for asulam determination based on in-situ generation of quantum dots. AB - Inspired by the photoelectrochemical (PEC) properties of TiO2 nanotubes arrays (TNA) and their application as a super vessel for immobilizing biomolecules, we constructed an inhibition-effect PEC biosensor for determination of asulam based on the in-situ generation of CdS quantum dots (QDs) on TNA using an enzymatic reaction. Horseradish peroxidase (HRP) enzyme was covalently assembled on the inner-wall of TNAs, which exhibited good electrochemical and catalytic properties. In the mixture solution containing H2O2, CdY and S2O32-, HRP enzyme in TNAs catalyzed H2O2 reduce S2O32- to S2-. The generated S2- reacted with CdY to form CdS QDs in situ on the TNAs, improving the PEC performance of TNA under visible light irradiation. The photocurrent would decrease after addition of asulam due to its inhibitory effect towards HRP enzyme activity. Under the optimal experimental conditions, the constructed PEC TNA/HRP biosensor exhibited a satisfying linear range (0.02-2.0 ng mL-1), low limit of detection (4.1 pg mL 1) and good selectivity towards asulam determination, and has been successfully applied for the analysis of real environmental water samples with good accuracy of the recoveries ranged from 90% to 114%.

AB - BACKGROUND: The first evidence that the hazard ratio (HR) for methadone-specific death rises more steeply with age-group than for all drug-related deaths (DRDs) came from Scotland's cohort of 33,000 methadone-prescription clients. We aim to examine, for England, whether illicit opioid users' risk of methadone-specific death increases with age; and to pool age-related HRs for methadone-specific deaths with those for Scotland's methadone-prescription clients. METHODS: The setting is all services in England that provide publicly-funded, structured treatment for illicit opioid users, the methodology linkage of the English National Drug Treatment Monitoring System and mortality database, and key measurements are DRDs, methadone-specific DRDs, or heroin-specific DRDs, by age group and gender, with proportional hazards adjustment for substances used, injecting status and periods in/out of treatment. RESULTS: Linkage was achieved for 129,979 adults receiving prescribing treatment modalities for opioid dependence during April 2005 to March 2009 and followed-up for 378,009 person years (pys). There were 1,266 DRDs: 271 methadone-specific (7 per 10,000 pys: irrespective of gender) and 473 heroin-specific (15 per 10,000 pys for males, 7 for females). Methadone-specific DRD-rate per 10,000 person-years was 3.5 (95% CI: 2.7-4.4) at 18-34 years, 8.9 (CI: 7.3-10.5) at 35-44 years and 18 (CI: 13.8 21.2) at 45+ years; heroin-specific DRD-rate was unchanged with age. Relative to 25-34 years, pooled HRs for UK clients' methadone-specific deaths were: 0.87 at <25 years (95% CI: 0.56-1.35); 2.14 at 35-44 years (95% CI: 1.76-2.60); 3.75 at 45+ years (95% CI: 2.99-4.70). CONCLUSION: International testing and explanation are needed of UK's sharp age-related increase in the risk of methadone-specific death. Clients should be alerted that their risk of methadone-specific death increases as they age.

AB - BACKGROUND: Breast cancer is a challenge for women's health-related quality of life (QoL), compromising their physical health and emotional well-being. QoL is equally distributed among different social groups. The aim of this study to analyze the impact of clinical characteristics and social determinants of health on the QoL of a cohort of women diagnosed and/or treated for breast cancer between 2003 and 2013 in one of the main hospitals in Barcelona's public health network. METHODS: We performed a descriptive cross-sectional study in a cohort of 2235 women with various stages of breast cancer at different stages of their disease. Data were obtained using questionnaires QLQ-C30 and QLQ-BR23 from the European Organization for Research and Treatment of Cancer (EORTC), which include a set of functional and symptomatic scales. We conducted descriptive and bivariate analysis using the Chi-Square test and adjusted for relevant variables using logistic regression. The dependent variables were the functional scales of QoL and the independent variables were sociodemographic and clinical variables. RESULTS: We observed significant differences for most QoL functions. Women from the most disadvantaged class, those in social isolation, or those who had suffered relapses showed the poorest results for most of the function scales. In contrast, age had differential effects depending on the function studied. CONCLUSIONS: The QoL of women diagnosed with breast cancer is closely linked to both their social and economic status, and to their stage of disease progression. It is necessary to explore interventions that focus on the social determinants of health in order to mitigate their effects on breast cancer survivors' QoL.

PMID- 29573625 TI - Metabolism profiling of nevadensin in vitro and in vivo by UHPLC-Q-TOF-MS/MS. AB - Nevadensin is major constituents of Lysionotus pauciflorus Maxim. (Chinese name: Shidiaolan), which has a variety of pharmacological effects such as anti mycobacterium tuberculosis activities, antitussive, anti-inflammatory and anti hypertensive. In this paper, we investigated the metabolism of nevadensin in vitro and in vivo. A strategy was firstly developed to identify the metabolites of nevadensin by using ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS). An on-line data acquisition method a multiple mass defect filter (MMDF) combined with dynamic background subtraction (DBS) was developed to trace all probable metabolites. Furthermore, some assistant tools, such as key fragment ions (KFI), were employed for compound hunting and identification. Based on the proposed method, 23 metabolites were structurally characterized in vivo including 16 phase I and 7 phase II metabolites, and 12 metabolites were detected in vitro containing 10 phase I and 2 phase II metabolites. The results indicated that oxidation, hydrolysis, demethylation, methylation, sulfate conjugation and glucuronide conjugation were main metabolic pathways of nevadensin. In a word, this study maybe can provide reference and valuable evidence for further investigation of the metabolic mechanism of nevadensin. PMID- 29573626 TI - Effects of combined oral contraception containing drospirenone on premenstrual exacerbation of Meniere's disease: Preliminary study. AB - OBJECTIVES: Meniere's disease is caused by an augmented endolymph pressure in the inner ear; symptoms are vertigo, fluctuating hearing loss and tinnitus. Exacerbations has been noted during premenstrual phase. The study aims to evaluate the effects of a 20 MUm Ethinylestradiol (EE) and 3 mg Drospirenone (DRSP) oral contraceptive (20 MUmEE/3mgDRSP) in continuous regimen, associated with rehabilitation therapy on Meniere's disease. STUDY DESIGN: This non randomized controlled study was performed from October 2015 to October 2017. Forty-two premenopausal women affected by MD with severe distress in the premenstrual phase were enrolled. Sixteen women constituted the study group (Group A), and twenty women constituted the control group (Group B). Group A underwent EE/DRSP therapy and rehabilitation and Group B underwent rehabilitation therapy alone. Stabilometry and the Dizziness Handicap Inventory questionnaire were used to measure vestibular function and distress related to the disease, respectively, at baseline (T0), 3 months (T1) and 6 months (T2). RESULTS: At T0, both groups had large, similar areas of stabilometric ellipses (p = NS) that reduced more in Group A than in Group B, at T1 and T2 (p < 0.001). High scores of the DHI (cut-off <=54) were observed at T0 in both groups (A 66.8 +/- 2.8 vs B 65.5 +/- 3.6; p = NS). At T1, a gradual improvement in both groups was observed, manly in Group A (A 45.1 +/- 3.6 vs B 62.4 +/- 4.1; p < 0.001). At T2, the DHI scores were significantly lower in Group A (39.2 +/- 3.8) compared to Group B (68.8 +/- 3.6) (p < 0.001). CONCLUSIONS: DRSP could be effective in reducing the fluid overload typical of the premenstrual phase, improving symptoms of MD. The results support the efficacy of EE/DRSP usage associated with rehabilitation therapy on premenstrual exacerbation of MD. PMID- 29573627 TI - Intraoperative enhanced imaging for detection of endometriosis: A systematic review of the literature. AB - The diagnosis of peritoneal endometriosis during laparoscopy may be difficult due to the polymorphic aspects of the lesions. Enhanced imaging using contrast agents has potential to provide a better identification of peritoneal endometriosis. The aim of this systematic review is to provide an overview of the literature on what is known about the intraoperative laparoscopic visual enhancement of peritoneal endometriosis using contrast agents. A systematic review was done of studies about enhanced imaging during laparoscopy for endometriosis using contrast agents. Clinical studies which contained a description of imaging with a contrast agent and also reported visual findings of endometriosis during laparoscopy, were included. Nine suitable studies were identified. Intraoperative visualization of endometriosis was analyzed with or without histologic confirmation. Four studies evaluated 5-aminolevulinic acid-induced fluorescence (5-ALA), 1 study evaluated indigo carmine, 2 studies evaluated methylene blue (MB), 1 study evaluated indocyanine green (ICG) and 1 study evaluated so-called bloody peritoneal fluid painting. All studies, with a combined total of 171 included patients, showed potential of enhanced visibility of endometriosis using contrast agents. A combined total of 7 complications, all related to the use of 5-ALA, were reported. We conclude that the use of contrast-based enhanced imaging during laparoscopy is promising and that it can provide a better visualization of peritoneal endometriosis. However, based on the limited data no technique of preference can yet be identified. PMID- 29573628 TI - Removal of organic compounds from shale gas flowback water. AB - Ozonation, sorption to granular activated carbon and aerobic degradation were compared as potential treatment methods for removal of dissolved organic carbon (DOC) fractions and selected organic compounds from shale gas flowback water after pre-treatment in dissolved air flotation unit. Flowback water was characterised by high chemical oxygen demand and DOC. Low molecular weight (LMW) acids and neutral compounds were the most abundant organic fractions, corresponding to 47% and 35% of DOC respectively. Ozonation did not change distribution of organic carbon fractions and concentrations of detected individual organic compounds significantly. Sorption to activated carbon targeted removal of individual organic compounds with molecular weight >115 Da, whereas LMW compounds remained largely unaffected. Aerobic degradation was responsible for removal of LMW compounds and partial ammonium removal, whereas formation of intermediates with molecular weight of 200-350 Da was observed. Combination of aerobic degradation for LMW organics removal with adsorption to activated carbon for removal of non-biodegradable organics is proposed to be implemented between pre-treatment (dissolved air floatation) and desalination (thermal or membrane desalination) steps. PMID- 29573629 TI - Oxidation of steroid estrogens by peroxymonosulfate (PMS) and effect of bromide and chloride ions: Kinetics, products, and modeling. AB - Recently, in situ chemical oxidation (ISCO) using peroxymonosulfate (PMS) for environmental decontamination has received increasing interest. In this study, oxidation kinetics and products of four steroid estrogens (i.e., estrone, 17beta estradiol, estriol, and 17alpha-ethinylestradiol) by PMS under various conditions were investigated. PMS could fairly degrade steroid estrogens over the pH range of 7-10, and the degradation rate increased with the increase of solution pH. This pH-dependence was well described by parallel reactions between individual acid-base species of steroid estrogens (E and E-) and PMS (HSO5- and SO52-), where specific second-order rate constants for E- with HSO5- and SO52- were in the range of 2.11-5.58 M-1s-1 and 0.77-1.25 M-1s-1, respectively. Identification of oxidation products by liquid chromatography/electrospray ionization quadrupole time-of-flight mass spectrometer showed that PMS readily oxidized the phenolic group of steroid estrogens, leading to the generation of hydroxylated and ring opening products. The presence of bromide and chloride ions (Br- and Cl-) at environmentally relevant levels could greatly accelerate the degradation of steroid estrogens by PMS with the formation of halogenated aromatic products. This effect was quantitatively estimated by a kinetic model, where the formation of free bromine and chorine and their rapid electrophilic substitution with steroid estrogens were taken into consideration. Eco-toxicity of transformation products of 17alpha-ethinylestradiol by PMS treatment in the absence and presence of bromide and chloride was estimated by quantitative structure-activity relationship analysis using ECOSAR. These findings advance the understanding of ISCO using PMS. PMID- 29573630 TI - Removals of pesticides and pesticide transformation products during drinking water treatment processes and their impact on mutagen formation potential after chlorination. AB - Removal efficiencies of 28 pesticide transformation products (TPs) and 15 parent pesticides during steps in drinking water treatment (coagulation-sedimentation, activated carbon adsorption, and ozonation) were estimated via laboratory-scale batch experiments, and the mechanisms underlying the removal at each step were elucidated via regression analyses. The removal via powdered activated carbon (PAC) treatment was correlated positively with the log Kow at pH 7. The adjusted coefficient of determination (r2) increased when the energy level of the highest occupied molecular orbital (HOMO) was added as an explanatory variable, the suggestion being that adsorption onto PAC particles was largely governed by hydrophobic interactions. The residual error could be partly explained by pi-pi electron donor-acceptor interactions between the graphene surface of the PAC particles and the adsorbates. The removal via ozonation correlated positively with the energy level of the HOMO, probably because compounds with relatively high energy level HOMOs could more easily transfer an electron to the lowest unoccupied molecular orbital of ozone. Overall, the TPs tended to be more difficult to remove via PAC adsorption and ozonation than their parent pesticides. However, the TPs that were difficult to remove via PAC adsorption did not induce strong mutagenicity after chlorination, and the TPs that were associated with strong mutagenicity after chlorination could be removed via PAC adsorption. Therefore, PAC adsorption is hypothesized to be an effective method of treating drinking water to reduce the possibility of post-chlorination mutagenicity associated with both TPs and their parent pesticides. PMID- 29573631 TI - Emerging contaminants and nutrients synergistically affect the spread of class 1 integron-integrase (intI1) and sul1 genes within stable streambed bacterial communities. AB - Wastewater effluents increase the nutrient load of receiving streams while introducing a myriad of anthropogenic chemical pollutants that challenge the resident aquatic (micro)biota. Disentangling the effects of both kind of stressors and their potential interaction on the dissemination of antibiotic resistance genes in bacterial communities requires highly controlled manipulative experiments. In this work, we investigated the effects of a combined regime of nutrients (at low, medium and high concentrations) and a mixture of emerging contaminants (ciprofloxacin, erythromycin, sulfamethoxazole, diclofenac, and methylparaben) on the bacterial composition, abundance and antibiotic resistance profile of biofilms grown in artificial streams. In particular, we investigated the effect of this combined stress on genes encoding resistance to ciprofloxacin (qnrS), erythromycin (ermB), sulfamethoxazole (sul1 and sul2) as well as the class 1 integron-integrase gene (intI1). Only genes conferring resistance to sulfonamides (sul1 and sul2) and intI1 gene were detected in all treatments during the study period. Besides, bacterial communities exposed to emerging contaminants showed higher copy numbers of sul1 and intI1 genes than those not exposed, whereas nutrient amendments did not affect their abundance. However, bacterial communities exposed to both emerging contaminants and a high nutrient concentration (1, 25 and 1 mg L-1 of phosphate, nitrate and ammonium, respectively) showed the highest increase on the abundance of sul1 and intI1 genes thus suggesting a factors synergistic effect of both stressors. Since none of the treatments caused a significant change on the composition of bacterial communities, the enrichment of sul1 and intI1 genes within the community was caused by their dissemination under the combined pressure exerted by nutrients and emerging contaminants. To the best of our knowledge, this is the first study demonstrating the contribution of nutrients on the maintenance and spread of antibiotic resistance genes in streambed biofilms under controlled conditions. Our results also highlight that nutrients could enhance the effect of emerging contaminants on the dissemination of antibiotic resistance. PMID- 29573633 TI - Influence of laser therapy on the dynamic formation of extracellular matrix in standard second degree burns treated with bacterial cellulose membrane. AB - The present study aims to assess the influence of Aluminum-Gallium-Indium Phosphide laser (AlGaInP laser, lambda = 660 nm), whether or not in association with the application of a membrane of bacterial cellulose (NexfillTM), during recovery from induced second-degree burns at the dorsum of Wistar rats. (Rattus norvegicus, Wistar). Forty-eight animals have been distributed into four groups: Control (burns remained untreated), Group I (laser-treated), Group II (treated with Nexfill), and Group III (laser + NexfillTM). In addition to a morphological analysis, immunohistochemical analysis has been performed for type I collagen, type III collagen, fibronectin, and laminin. The Fisher's Test was used to assess differences among groups (p < 0,05). A larger amount of collagen type III was observed in Control, Group II and Group III when compared with Group I (p < 0,05). Group I and Group III have shown a greater collagen deposition when compared with Group II (p < 0,05), but the amount of collagen was similar in Group I, Group III, and Control. Group III has shown larger fibronectin amounts in comparison with Group II (p < 0,05). As regards laminin, Group I has shown a predominant discontinuity pattern on the basal lamina in comparison with Control, Group II, and Group III (p < 0,05). It is concluded that in this current study the laser when used alone (Group I) hasn't influenced collagen deposition neither has it acted on fiber pattern (fibril and/or reticular). Moreover, laser application hasn't accelerated the repair of wounds caused by inflicted second degree burns. PMID- 29573632 TI - Assessing the origin of bacteria in tap water and distribution system in an unchlorinated drinking water system by SourceTracker using microbial community fingerprints. AB - The general consensus is that the abundance of tap water bacteria is greatly influenced by water purification and distribution. Those bacteria that are released from biofilm in the distribution system are especially considered as the major potential risk for drinking water bio-safety. For the first time, this full scale study has captured and identified the proportional contribution of the source water, treated water, and distribution system in shaping the tap water bacterial community based on their microbial community fingerprints using the Bayesian "SourceTracker" method. The bacterial community profiles and diversity analyses illustrated that the water purification process shaped the community of planktonic and suspended particle-associated bacteria in treated water. The bacterial communities associated with suspended particles, loose deposits, and biofilm were similar to each other, while the community of tap water planktonic bacteria varied across different locations in distribution system. The microbial source tracking results showed that there was not a detectable contribution of source water to bacterial community in the tap water and distribution system. The planktonic bacteria in the treated water was the major contributor to planktonic bacteria in the tap water (17.7-54.1%). The particle-associated bacterial community in the treated water seeded the bacterial community associated with loose deposits (24.9-32.7%) and biofilm (37.8-43.8%) in the distribution system. In return, the loose deposits and biofilm showed a significant influence on tap water planktonic and particle-associated bacteria, which were location dependent and influenced by hydraulic changes. This was revealed by the increased contribution of loose deposits to tap water planktonic bacteria (from 2.5% to 38.0%) and an increased contribution of biofilm to tap water particle-associated bacteria (from 5.9% to 19.7%) caused by possible hydraulic disturbance from proximal to distal regions. Therefore, our findings indicate that the tap water bacteria could possibly be managed by selecting and operating the purification process properly and cleaning the distribution system effectively. PMID- 29573634 TI - Human serum albumin binding to the biologically active labdane diterpene "leoheterin": Spectroscopic and in silico analysis. AB - Labdane diterpenes are important substances due to their remarkable biological activities such as, antibacterial, antiprotozoal, antifungal and cytostatic and cytotoxic effects against human cancer cells. We have isolated a labdane diterpene named "leoheterin" from the aerial parts of the Otostegia fruticosa Forssk (Briq) obtained from south west Arabian mountains of Saudi Arabia. The isolated compound was characterized by 1HNMR, 13CNMR, IR and UV-visible spectroscopies. Due to the pharmaceutical importance of this class of compounds we have studied the interaction of HSA with leoheterin by using several spectroscopic methods. The change in the UV spectrum of HSA in presence of leoheterin gives a primary idea about the interaction between them. Congruently, leoheterin quenches the fluorescence of HSA with a prominent blue shift of 5 nm, reminiscent of involvement of hydrophobic interactions. There was 1:1 binding between leoheterin and albumin which was taken place via static quenching mechanism. From CD it was revealed that leoheterin induces the secondary structure of HSA which is further supported by 3-d fluorescence measurements which shows a decrease in the size of the HSA-leoheterin complex as compared to the HSA alone. Molecular docking simulations presented that among the first three conformers, which have been arranged according to the least binding energies and are also in good corroboration with the free energies of binding obtained experimentally, the first two conformers shown the binding in hemin binding site of subdomain IB while in third conformer the binding site was near to the drug binding site 1 located in subdomain IIA. All conformers exhibited the involvement of hydrogen bonding as well as hydrophobic interactions. PMID- 29573635 TI - Fabrication of multi-functional porous microspheres in a modular fashion for the detection, adsorption, and removal of pollutants in wastewater. AB - Water pollution control has become significant challenges in recent years because of their extensive species diversity. It is critical to developing general purpose materials for environmental rehabilitation. In this paper, a novel module assembly method is developed to prepare multi-functional materials for treating pollutants in water. Building blocks are porous nanoparticles with a different function. Microspheres (MS) with a diameter of 90 MUm are prepared and have a coefficient of variation of 6.8%. The modular fashion of self-assembly process in a microfluidic chip is the crucial factor in fabricating the multifunction material. The assembled microspheres with different building modules still have a specific surface area larger than 400 m2 g-1, and exhibit excellent performance in adsorbing various pollutants in water, such as heavy metal ions and organic dyes. The adsorption capacities of them to Hg2+ and orange II reach 150 mg g-1 and 333 mg g-1, respectively. The integrated fluorescence probes in microspheres can detect low concentration (9.8 ppb) of Hg2+. Microspheres integrated with Fe3O4 nanoparticles have a magnetic susceptibility of 6.01 emu g-1 and can be easily removed from wastewater by applying an external magnetic. Due to the stability of inorganic building blocks, each function in the assembled system is well performed, and multi-functional "All-in-One" materials can be easily fabricated. PMID- 29573636 TI - POH1 Knockdown Induces Cancer Cell Apoptosis via p53 and Bim. AB - The ubiquitin-proteasome system is implicated in cell apoptosis that is frequently dysregulated in human cancers. POH1/rpn11/PSMD14, as a part of the 19S proteasomal subunit, contributes to the progression of malignancy, but its role in apoptosis remains unclear. Here, we showed that POH1 expression was increased and associated with poor outcomes in three independent cohorts of patients with hepatocellular carcinoma (HCC), esophageal cancer (EC), and colorectal cancer (CRC). The knockdown of POH1 significantly inhibited tumor cell proliferation and induced apoptosis mediated by the mitochondrial pathway in vitro. Intratumoral injection of POH1 small interfering RNA (siRNA) significantly reduced the progression of tumor growth and induced apoptosis in vivo. Furthermore, p53 or Bim siRNA markedly attenuated the apoptosis induced by POH1 depletion. POH1 depletion resulted in cell apoptosis by increasing the stability of p53 and Bim and inhibiting their ubiquitination. Overall, POH1 knockdown induced cell apoptosis through increased expression of p53 and Bim via enhanced protein stability and attenuated degradation. Thus, POH1 may serve as a potential prognostic marker and therapeutic target in human cancers. PMID- 29573637 TI - Development of a New Monochrome Multiplex qPCR Method for Relative Telomere Length Measurement in Cancer. AB - Excess telomere shortening has been observed in most cancer cells. The telomere quantitative polymerase chain reaction (qPCR) assay has become an important tool for epidemiological studies examining the effects of aging, stress, and other factors on the length of telomeres. Current telomere qPCR methods analyze the relative length of telomeres by amplifying telomere sequence products and normalizing with single-copy gene products. However, the current telomere qPCR does not always reflect absolute telomere length in cancer DNA. Because of genomic instability in cancer cells, we hypothesized that the use of single-copy genes (scg) is less accurate for normalizing data in cancer DNA and that new primer sets are required to better represent relative telomere length in cancer DNA. We first confirmed that cancer cells had a different copy ratio among different scg, implying that DNA is aneuploid. By using the new primer sets that amplify multiple-copy sequences (mcs) throughout the genome, the telomere qPCR results showed that the mcs primers were interchangeable with the scg primers as reference primers in normal DNA. By comparing results from the traditional southern blotting method (as kilobases) and results from monochrome multiplex qPCR using the mcs primers (as T/M ratios), we verified that the T/M ratio is highly correlated with absolute telomere length from the southern blot analysis. Together, the mcs primers were able to represent the telomere lengths accurately in cancer DNA samples. These results would allow for analyses of telomeres within cancerous DNA and the development of new, less invasive diagnostic tools for cancer. PMID- 29573638 TI - N-linoleoylamino acids as chiral probes of substrate binding by soybean lipoxygenase-1. AB - Lipoxygenases catalyze the oxygenation of polyunsaturated fatty acids and their derivatives to produce conjugated diene hydroperoxides. Soybean lipoxygenase-1 (SBLO-1) has been the subject of intensive structural and mechanistic study, but the manner in which this enzyme binds substrates is uncertain. Previous studies suggest that the fatty acyl group of the substrate binds in an internal cavity near the catalytic iron with the polar end at the surface of the protein or perhaps external to the protein. To test this model, we have investigated two pairs of enantiomeric N-linoleoylamino acids as substrates for SBLO-1. If the amino acid moiety binds external to the protein, the kinetics and product distribution should show little or no sensitivity to the stereochemical configuration of the amino acid moiety. Consistent with this expectation, N linoleoyl-l-valine (LLV) and N-linoleoyl-d-valine (LDV) are both good substrates with kcat/Km values that are equal within error and about 40% higher than kcat/Km for linoleic acid. Experiments with N-linoleoyl-l-tryptophan (LLT) and N linoleoyl-d-tryptophan (LDT) were complicated by the low critical micelle concentrations (CMC = 6-8 MUM) of these substances. Below the CMC, LDT is a better substrate by a factor of 2.7. The rates of oxygenation of LDT and LLT continue to rise above the CMC, with modest stereoselectivity in favor of the d enantiomer. With all of the substrates tested, the major product is the 13(S) hydroperoxide, and the distribution of minor products is not appreciably affected by the configuration of the amino acid moiety. The absence of stereoselectivity with LLV and LDV, the modest magnitude of the stereoselectivity with LLT and LDT, and the ability micellar forms of LLT and LDT to increase the concentration of available substrate are all consistent with the hypothesis that the amino acid moiety binds largely external to SBLO-1 and interacts with it only weakly. PMID- 29573639 TI - Integrin alphavbeta6 Promotes Lung Cancer Proliferation and Metastasis through Upregulation of IL-8-Mediated MAPK/ERK Signaling. AB - Lung cancer is notorious for high morbidity and mortality around the world. Interleukin (IL)-8, a proinflammatory chemokine with tumorigenic and proangiogenic effects, promotes lung cancer cells growth and migration and contributes to cell aggressive phenotypes. Integrin alphavbeta6 is a receptor of transmembrane heterodimeric cell surface adhesion, and its overexpression correlates with poor survival from non-small cell lung cancer. However, the cross talk between alphavbeta6 and IL-8 in lung cancer has not been characterized so far. Herein, human lung cancer samples were analyzed, and it revealed that the immunohistochemical and mRNA expression of integrin alphavbeta6 was significantly correlated with the expression of IL-8. Furthermore, in vitro, integrin alphavbeta6 increased cell proliferation, migration, and invasion by impairing the expressions of MMP-2 and MMP-9 and inhibited cell apoptosis in human lung cancer cells A549 and H460. In addition, integrin alphavbeta6 upregulated IL-8 expression through activating MAPK/ERK signaling. The in vivo experiment showed that integrin alphavbeta6 promoted tumor growth in xenograft model mice by accelerating tumor volume and reducing apoptosis. Meanwhile, lung metastasis model experiment suggested that integrin alphavbeta6 stimulated tumor metastasis with the increase of lung/total weight and tumor nodules. Simultaneously, integrin alphavbeta6 upregulated IL-8 expression detected by both Western blots and immunohistochemistry, along with the activation of MAPK/ERK signaling. Overall, these data suggested that, in vitro and in vivo, integrin alphavbeta6 promoted lung cancer proliferation and metastasis, at least in part, through upregulation of IL-8-mediated MAPK/ERK signaling. Thus, the inhibition of integrin alphavbeta6 and IL-8 may be the key for the treatment of lung cancer. PMID- 29573640 TI - Tipping microtubule dynamics, one protofilament at a time. AB - Microtubules are polymeric tubes that switch between phases of growth and shortening, and this property is essential to drive key cellular processes. Microtubules are composed of protofilaments formed by longitudinally arranged tubulin dimers. Microtubule dynamics can be affected by structural perturbations at the plus end, such as end tapering, and targeting only a small subset of protofilaments can alter the dynamics of the whole microtubule. Microtubule lattice plasticity, including compaction along the longitudinal axis upon GTP hydrolysis and tubulin dimer loss and reinsertion along microtubule shafts can also affect microtubule dynamics or mechanics. Microtubule behaviour can be fine tuned by post-translational modifications and tubulin isotypes, which together support the diversity of microtubule functions within and across various cell types or cell cycle and developmental stages. PMID- 29573641 TI - Impact sites representing potential bruising locations associated with bed falls in children. AB - Bruising can occur as a result of accidental or abusive trauma in children. Bruises are an early sign of child abuse and their locations on the body can be an effective delineator of abusive trauma. Since falls are often reported as false histories in abuse, the ability to predict potential bruising locations in falls could be valuable when attempting to differentiate between abuse and accident. In our study we used an anthropomorphic test device (ATD), a surrogate representing a 12 month old child, adapted with a custom developed force sensing skin to predict potential bruising locations during simulated bed falls. The sensing skin is made of custom resistive force sensors integrated into a conformable skin, adapted to fit the contours of the ATD. The sensing skin measured and displayed recorded force data on a computerized body image mapping system when sensors were activated. Simulated bed fall experiments were performed from two initial positions (FF - facing forward and FR - facing rearward) and two fall heights of 61cm (24 in) and 91cm (36 in) onto a padded carpet impact surface. Findings indicated potential bruising primarily in two planes of the ATD body. The majority of contact regions and greater forces were recorded in one plane, with fewer regions of contact and decreased force exhibited in an adjoining second plane. Additionally, no contact was recorded in the two planes opposite the impact planes. Differences in contact regions were observed for varying heights and initial position. Limitations of ATD biofidelity and soft tissue properties must be considered when interpreting these findings. PMID- 29573642 TI - Analytical and transfer characteristics of a fluorescent detection spray: Implications for subvisible and nanotrace particle transfers. AB - Fluorescent detection sprays are applied to objects to elucidate evidence of contact. Billed as an invisible powder, evidence of contact between objects may be visualized through illumination by ultra-violet light, which causes the fluorescent tracer to luminesce. While the presence of the fluorescent powder on a suspect or object is often used as evidence of direct contact, the fine nature of the powder, which is comprised of sub-visible particles that are generally less than 10 MUm in diameter, lends itself to higher-order transfers that do not necessarily involve the original object. Due to the small particle size and light yellow color, the particles are generally invisible to the unaided eye in white light. This increases the opportunity for unwanted or unanticipated transfers (i.e., contamination). This article provides a microanalytical characterization of a common fluorescent tracer and the approaches by which this powder (or analogous powders) may be applied, detected, and specifically identified in quantities that range from major to trace. This research illustrates the ease of higher order cross-transfers (up to the 10th order) and the considerations necessary to maximize the evidentiary value of sub-visible particles and nanotraces, while minimizing the chances of cross-contamination.

The sample consisted of 1196 bullying victims in grades 8 10 (Mage = 14.4, SD = 1.01) who participated in The Context Study in three North Carolina counties in Fall 2003. Five profiles were identified using latent profile analysis: an asymptomatic profile and four profiles capturing combinations of internalizing and externalizing symptoms. Associations between bullying characteristics and membership in symptom profiles were tested using multinomial logistic regression. More frequent victimization increased odds of membership in the two high internalizing profiles compared to the asymptomatic profile. Across all multinomial logistic regression models, when the high internalizing, high externalizing profile was the reference category, adolescents who received any type of bullying (direct, indirect, or dual) were more likely to be in this category than any others. PMID- 29573644 TI - Intimacy development in late adolescence: Longitudinal associations with perceived parental autonomy support and adolescents' self-worth. AB - The present longitudinal study tested for the role of perceived parental autonomy support and late adolescents' self-worth in their intimacy development. A sample of 497 Belgian late adolescents (Mage = 17.9, 43.5% girls) participated in this two-wave study. Results indicated that perceived autonomy-supportive parenting did not relate significantly to change in adolescents' experienced intimacy (in terms of closeness and mutuality), but was associated with a decrease in unmitigated agency (an excessive focus on the self) and unmitigated communion (an excessive focus on the other) across time. Adolescents' self-worth predicted an increase in experienced intimacy and a decrease in unmitigated agency and communion, and the initial level of experienced intimacy predicted an increase in self-worth. Finally, results suggested that adolescents' self-worth may mediate some of the longitudinal relations between perceived parental autonomy-support and adolescents' intimate functioning. No evidence was found for moderation by romantic involvement, gender or age.

AB - According to the self-teaching hypothesis (Share, 1995), phonological decoding is fundamental to acquiring orthographic representations of novel written words. However, phonological decoding is not straightforward in non-alphabetic scripts such as Chinese, where words are presented as characters. Here, we present the first study investigating the role of phonological decoding in orthographic learning in Chinese. We examined two possible types of phonological decoding: the use of phonetic radicals, an internal phonological aid, andthe use of Zhuyin, an external phonological coding system. Seventy-three Grade 2 children were taught the pronunciations and meanings of twelve novel compound characters over four days. They were then exposed to the written characters in short stories, and were assessed on their reading accuracy and on their subsequent orthographic learning via orthographic choice and spelling tasks. The novel characters were assigned three different types of pronunciation in relation to its phonetic radical - (1) a pronunciation that is identical to the phonetic radical in isolation; (2) a common alternative pronunciation associated with the phonetic radical when it appears in other characters; and (3) a pronunciation that is unrelated to the phonetic radical. The presence of Zhuyin was also manipulated. The children read the novel characters more accurately when phonological cues from the phonetic radicals were available and in the presence of Zhuyin. However, only the phonetic radicals facilitated orthographic learning. The findings provide the first empirical evidence of orthographic learning via self-teaching in Chinese, and reveal how phonological decoding functions to support learning in non-alphabetic writing systems. PMID- 29573646 TI - Evaluation of interleukin-1beta level and oxidative status in gingival crevicular fluid during rapid maxillary expansion. AB - OBJECTIVES: The levels of interleukin-1beta (IL-1beta), nitric oxide (NO), total antioxidant capacity (TAC), and total oxidant status (TOS) in gingival crevicular fluid (GCF) were determined during rapid maxillary expansion (RME) treatment. MATERIALS AND METHODS: Fourteen patients (10-13 years old) were included. A modified hyrax appliance was used for the treatment. After periodontal parameters were recorded, GCF was collected from the first molars at each observation [T1:baseline:14 days after periodontal prophylaxis and instructions; T2:1 day later hyrax inserted, at passive position; T3:1 week later; after the first activation; T4:after 2 * 1/4 activation; T5:after 7 * 1/4 activation; T6:after 14 * 1/4 activation; T7:retention period on the 1 st month; and T8:retention period on the 3rd month]. RESULTS: Although the levels of IL1-beta, NO, and PD increased significantly from T1 to T2, the GI, BOP%, and PI remained unchanged throughout treatment. GCF volume at buccal and palatal surfaces increased significantly from T1 to T4, T6, T7, and T8. The parameters in GCF and TAC levels were not only higher at palatal side in comparison with buccal, but also TOS levels increased at both buccal and palatal sides. CONCLUSIONS: In this study, the differences of oxidative status and IL-1beta levels during RME treatment could be attributable to orthopedic effect of the heavy forces on maxilla and minimal orthodontic forces on teeth applied by the RME apparatus. PMID- 29573647 TI - Oral spray containing plant-derived compounds is effective against common oral pathogens. AB - OBJECTIVES: Plant-derived compounds are a good source of therapeutic agents and inhibitors of inflammatory process. Dental caries, periodontal diseases and candidiasis are common oral infections caused by virulent biofilms. The objectives of this study were to develop oral spray containing plant-derived compounds; alpha-mangostin (alpha-MG) and/or lawsone methyl ether (2-methoxy-1,4 naphthoquinone) (LME) and determine its antimicrobial, anti-biofilm, and anti inflammatory activities. DESIGN: Oral spray formulations were prepared containing alpha-MG (5 mg/ml) and/or LME (250 MUg/ml). Antimicrobial activity against Candida albicans, Streptococcus mutans, and Porphyromonas gingivalis and anti biofilm formation activities were determined as well as cytotoxicity and anti inflammatory effects. RESULTS: The oral spray demonstrated antimicrobial activity against all three of the oral pathogens tested with stronger effects on C. albicans and S. mutans than P. gingivalis. The formulation containing alpha-MG (2.5 mg/ml) and LME (125 ug/ml) reduced growth of the microorganisms about 1-2 Log CFU/ml at 1-3 h and the killing effects were complete at 24 h. Based on biofilm assay, the oral spray containing both alpha-MG and LME showed greater inhibitory effects than those with alpha-MG or LME. In addition, the oral spray containing both alpha-MG and LME demonstrated more inhibition of nitric oxide production than alpha-MG alone. All the formulations were safe and demonstrated greater anti-inflammatory activity at lower concentration (<6.25 MUg/ml) than at a higher concentration. CONCLUSION: Oral spray containing alpha-MG and/or LME is effective against common oral pathogens without significant cytotoxicity. Thus, it has the potential to prevent the infections and may serve as adjunctive treatment to conventional therapy. PMID- 29573648 TI - Atomoxetine for amphetamine-type stimulant dependence during buprenorphine treatment: A randomized controlled trial. AB - BACKGROUND: Amphetamine type stimulants (ATS) use is highly prevalent and frequently co-occurs with opioid dependence in Malaysia and Asian countries. No medications have established efficacy for treating ATS use disorder. This study evaluated the safety, tolerability, and potential efficacy of atomoxetine for treating ATS use disorder. METHODS: Participants with opioid and ATS dependence (N = 69) were enrolled in a pilot, double-blind, placebo-controlled randomized clinical trial; all received buprenorphine/naloxone and behavioral counseling and were randomized to atomoxetine 80 mg daily (n = 33) or placebo (n = 33). The effect size of the between-group difference on the primary outcome, proportion of ATS-negative urine tests, was estimated using Cohen's d for the intention-to treat (ITT) sample and for higher adherence subsample (>=60 days of atomoxetine or placebo ingestion). RESULTS: Participants were all male with mean (SD) age 39.4 (6.8) years. The proportion of ATS-negative urine tests was higher in atomoxetine- compared to placebo-treated participants: 0.77 (0.63-0.91) vs. 0.67 (0.53-0.81, d = 0.26) in the ITT sample and 0.90 (0.75-1.00) vs. 0.64 (0.51-0.78, d = 0.56) in the higher adherence subsample. The proportion of days abstinent from ATS increased from baseline in both groups (p < 0.001) and did not differ significantly between atomoxetine- and placebo-treated participants (p = 0.42). Depressive symptoms were reduced from baseline in both groups (p < 0.02) with a greater reduction for atomoxetine- than placebo-treated participants (p < 0.02). There were no serious adverse events or adverse events leading to medication discontinuation. CONCLUSIONS: The findings support clinical tolerability and safety and suggest potential efficacy of atomoxetine for treating ATS use disorder in this population. PMID- 29573649 TI - Perceptions and practices addressing diversion among US buprenorphine prescribers. AB - BACKGROUND: While there has been a dramatic increase in prescribing of buprenorphine for the treatment of opioid use disorder in the US, little is known about prescribers' attitudes and practices regarding buprenorphine diversion and how they relate to prescriber characteristics. METHODS: A national random sample of buprenorphine prescribers (N = 1174) completed surveys from July 2014 to January 2017. Analyses examined relationships between prescriber and practice characteristics and prescriber perceptions and approaches regarding diversion. RESULTS: Among this sample of buprenorphine prescribers, 79.0% (N = 898) reported assessing all patients for risk of buprenorphine diversion and misuse. A third of prescribers described diversion as a significant or very significant concern in their community. The majority of prescribers reported seeing patients on average at least every other week during the first 60 days of treatment, and the majority reported testing urine for buprenorphine to assess for diversion. Perceptions of diversion being a greater problem in their community (AOR 1.212, 95% CI 1.073 1.369) and use of medication counts (AOR 1.006, 95% CI 1.003-1.009) were associated with increased likelihood of terminating patients when diversion was suspected, while having expertise in addiction (AOR 0.526, 95% CI 0.406-0.682) or psychiatry (AOR 0.714, 95% CI 0.558-0.914) were associated with decreased odds of terminating treatment for suspected diversion. CONCLUSIONS: Buprenorphine prescribers report diversion is an important issue, and most prescribers report that they assess patients for diversion, though specific practices differ based on prescriber and practice characteristics. PMID- 29573651 TI - Near infrared-emitting persistent luminescent nanoparticles for Hepatocellular Carcinoma imaging and luminescence-guided surgery. AB - Hepatocellular carcinoma (HCC), the fifth most common cancer worldwide, is increasing nowadays and poses a serious threat to human health. However, if treated effectively and timely, it is clinically manageable or curable. Therefore, accurate detection and complete surgical resection remain priorities for HCC with a high potential of improving both survival and quality of life. Lacking of real-time guide technology, traditional surgery are usually relied on the subjective experience of surgeon, which have the limitation of high sensitivity detection tumor. Here, we developed a contrast agent, ZnGa2O4Cr0.004 (ZGC), used for guided surgery during operation to accurate delineation of HCC. ZGC showed excellent long-lasting afterglow properties that lasted for hours, which can aid in real-time guided surgery. Meanwhile, ZGC display high spatial resolution and deep penetration during pre-operation for diagnostic computed tomography (CT). Interestingly, we observed reverse imaging in the tumor region, known as a "dark hole", which further improves the contrast for surgery. This new multi-modality nanoparticle has great potential for accurate liver cancer imaging and resection guidance. PMID- 29573650 TI - Does exposure to parental substance use disorders increase offspring risk for a substance use disorder? A longitudinal follow-up study into young adulthood. AB - OBJECTIVE: The main aim of this study was to examine the risk of exposure to parental substance use disorders (SUD; alcohol or drug abuse or dependence) on the risk for SUD in offspring with and without attention deficit hyperactivity disorder (ADHD) followed into young adult years. METHODS: Subjects were derived from two longitudinal case-control studies of probands of both sexes, 6-17 years, with and without DSM-III-R ADHD and their parents. Probands were followed for ten years into young adulthood. Probands with a parental history of non-nicotine SUD were included in this analysis. Exposure to SUD was determined by active non nicotine parental SUD while the parent was living with their child after birth. Cox proportional hazard models were used to calculate the risk of non-nicotine SUD in offspring. RESULTS: 171 of the 404 probands reassessed at ten-year follow up had a family history of parental SUD. 102 probands were exposed to active parental SUD. The average age of our sample was 22.2 +/- 3.5 years old. Exposure to maternal but not paternal SUD increased offspring risk for an alcohol use disorder in young adulthood independently of ADHD status (OR: 2.7; 95% CI: 1.1, 6.9; p = 0.04). CONCLUSION: Exposure to maternal SUD increases the risk for an alcohol use disorder in offspring ten years later in young adult years irrespective of ADHD status. PMID- 29573652 TI - The impact of emotional labor on the severity of PTSD symptoms in firefighters. AB - BACKGROUND: Despite attempts to identify predictors for posttraumatic stress disorder (PTSD) in firefighters, it is still uncertain whether occupational stress factors impact PTSD symptoms. Given the emotionally taxing job environment of firefighters, this population has been known to suffer from emotional labor. In this study, we investigated whether and how emotional labor, one of the occupational stress factors, influences the severity of PTSD symptoms in firefighters. METHODS: A total of 7151 Korean firefighters (age range 21-60 years, 6484 (90.7%) male participants) were included for analysis. PTSD symptoms were assessed using the PTSD Checklist-Civilian Version, and the demands of emotional labor and emotional damage were measured using the Korean Emotional Labor Scale. Hierarchical multivariate regression was performed. RESULTS: Hierarchical multivariate regression showed that a 2-way interaction between the presence of recent trauma and emotional damage was significantly associated with the severity of PTSD symptoms, even after adjusting for demographic factors, job related factors, and perceived stress. The independent main effects of emotional labor were not significantly associated with PTSD symptoms. CONCLUSION: These findings suggest that emotional labor can be a risk factor that makes firefighters vulnerable to PTSD symptoms by modulating the effect of traumatic experiences on PTSD symptoms. PMID- 29573654 TI - Pneumonia risk of people living close to goat and poultry farms - Taking GPS derived mobility patterns into account. AB - We previously observed an increased incidence of pneumonia in persons living near goat and poultry farms, using animal presence around the home to define exposure. However, it is unclear to what extent individual mobility and time spent outdoors close to home contributes to this increased risk. Therefore, the aim of the current study was to investigate the role of mobility patterns and time spent outdoors in the vicinity of goat or poultry farms in relation to pneumonia risk. In a rural Dutch cohort, 941 members logged their mobility using GPS trackers for 7 days. Pneumonia was diagnosed in 83 subjects (participants reported that pneumonia had been diagnosed by a medical doctor, or recorded in EMR from general practitioners, 2011-2014). We used logistic regression to evaluate pneumonia-risk by presence of goat farms within 500 and 1000 m around the home and around GPS tracks (only non-motorised mobility), also we evaluated whether more time spent outdoors increased pneumonia-risks. We observed a clearly increased risk of pneumonia among people living in close proximity to goat farms, ORs increased with closer distances of homes to farms (500 m: 6.2 (95% CI 2.2-16.5) 1000 m: 2.5 (1.4-4.3)) The risk increased for individuals who spent more time outdoors close to home, but only if homes were close to goat farms (within 500 m and often outdoors: 12.7 (3.6-45.4) less often: 2.0 (0.3-9.2), no goat farms and often outdoors: 1.0 (0.6-1.6)). For poultry we found no increased risks. Pneumonia risks increased when people lived near goat farms, especially when they spent more time outdoors, mobility does not seem to add to these risks. PMID- 29573653 TI - Maternal polymorphisms in glutathione-related genes are associated with maternal mercury concentrations and early child neurodevelopment in a population with a fish-rich diet. AB - INTRODUCTION: Glutathione (GSH) pathways play a key role the metabolism and elimination of the neurotoxicant methylmercury (MeHg). We hypothesized that maternal genetic variation linked to GSH pathways could influence MeHg concentrations in pregnant mothers and children and thereby also affect early life development. METHODS: The GCLM (rs41303970, C/T), GCLC (rs761142, T/G) and GSTP1 (rs1695, A/G) polymorphisms were genotyped in 1449 mothers in a prospective study of the Seychellois population with a diet rich in fish. Genotypes were analyzed in association with maternal hair and blood Hg, fetal blood Hg (cord blood Hg), as well as children's mental (MDI) and motor development (PDI; MDI and PDI assessed by Bayley Scales of Infant Development at 20 months). We also examined whether genotypes modified the association between Hg exposure and developmental outcomes. RESULTS: GCLC rs761142 TT homozygotes showed statistically higher mean maternal hair Hg (4.12 ppm) than G carriers (AG 3.73 and GG 3.52 ppm) (p = 0.037). For the combination of GCLC rs761142 and GCLM rs41303970, double homozygotes TT + CC showed higher hair Hg (4.40 ppm) than G + T carriers (3.44 ppm; p = 0.018). No associations were observed between GSTP1 rs1695 and maternal hair Hg or between any genotypes and maternal blood Hg or cord blood Hg. The maternal GSTP1 rs1695 rare allele (G) was associated with a lower MDI among children (beta = -1.48, p = 0.048). We also observed some interactions: increasing Hg in maternal and cord blood was associated with lower PDI among GCLC rs761142 TT carriers; and increasing Hg in hair was associated with lower MDI among GSTP1 rs1695 GG carriers. CONCLUSIONS: Maternal genetic variation in genes involved in GSH synthesis is statistically associated with Hg concentrations in maternal hair, but not in maternal or fetal blood. We observed interactions that suggest maternal GSH genetics may modify associations between MeHg exposure and neurodevelopmental outcomes. PMID- 29573655 TI - Drivers of contaminant levels in surface water of China during 2000-2030: Relative importance for illustrative home and personal care product chemicals. AB - Water pollution are among the most critical problems in China and emerging contaminants in surface water have attracted rising attentions in recent years. There is great interest in China's future environmental quality as the national government has committed to a major action plan to improve surface water quality. This study presents methodologies to rank the importance of socioeconomic and environmental drivers to the chemical concentration in surface water during 2000 2030. A case study is conducted on triclosan, a home and personal care product (HPCP) ingredient. Different economic and discharge flow scenarios are considered. Urbanization and wastewater treatment connection rates in rural and urban areas are collected or projected for 2000-2030 for counties across China. The estimated usage increases from ca. 86 to 340 t. However, emissions decreases from 76 to 52 t during 2000-2030 under a modelled Organisation for Economic Co operation (OECD) economic scenario because of the urbanization, migration and development of wastewater treatment plants/facilities (WWTPs). The estimated national median concentration of triclosan ranges 1.5-8.2 ng/L during 2000-2030 for different scenarios. It peaks in 2009 under the OECD and three of the Intergovernmental Panel on Climate Change (IPCC), A2, B1 and B2 economic scenarios, but in 2025 under A1 economic scenario. Population distribution and surface water discharge flow rates are ranked as the top two drivers to triclosan levels in surface water over the 30 years. The development of urban WWTPs was the most important driver during 2000-2010 and the development of rural works is projected to be the most important in 2011-2030. Projections suggest discharges of ingredients in HPCPs - controlled by economic growth - should be balanced by the major expenditure programme on wastewater treatment in China. PMID- 29573656 TI - Beck Self-Esteem Scale-Short Form: Development and psychometric evaluation of a scale for the assessment of self-concept in schizophrenia. AB - A requisite step for testing cognitive theories regarding the role of self concept in schizophrenia is the development of measures that follow a cognitive conceptualization and better capture the multifaceted nature of this construct. The purpose of this study was to examine the psychometric properties a new self concept measure, the Beck Self-Esteem Scale-Short Form (BSES-SF), based on a sample of 204 individuals with schizophrenia or schizoaffective disorder. We evaluated the BSES-SF's dimensionality, internal consistency reliability, and construct and divergent validity using confirmatory factor analysis, Cronbach's alpha, Pearson correlations, independent samples t-tests, and one-way analysis of variance. Findings indicate that the 10-item BSES-SF is a reliable and valid measure of self-concept that is appropriate for a broad group of individuals with schizophrenia spectrum disorders. Following cognitive theory, the scale demonstrated significant relationships with delusion severity, motivation, and depression, further signifying its utility for research and practice efforts that are designed to address psychopathology in schizophrenia. PMID- 29573657 TI - Reductions in self-blame cognitions predict PTSD improvements with cognitive processing therapy for military sexual trauma-related PTSD. AB - Reductions in trauma-related negative cognitions during Cognitive Processing Therapy (CPT) are theorized to precede posttraumatic stress disorder (PTSD) symptom reduction. This mechanism of change has not been validated for veterans with military sexual trauma-related PTSD. Using data from a previously published randomized clinical trial (n = 32), changes in trauma-related negative cognitions about self, self-blame, and the world were entered as predictors of change in PTSD symptoms for cross-lagged panel analyses. From baseline to 6-months posttreatment, only changes in self-blame predicted and temporally preceded changes in PTSD symptoms, highlighting a potential mechanism of change in CPT for military sexual trauma-related PTSD. PMID- 29573658 TI - Theory of mind in a first-episode psychosis population using the Hinting Task. AB - Deficiencies in theory of mind (ToM) are common in psychosis and may largely explain impaired social functioning. Currently, it is unclear whether impairments in ToM are explained by the more general cognitive deficits related to psychosis or whether ToM is impaired in psychosis independently of other cognitive deficits. This study examined ToM using the Hinting Task in young adults (n = 66) with first-episode psychosis and matched controls (n = 62). The participants were administered a broad neuropsychological assessment. Participants with psychosis performed worse than controls on the Hinting Task. However, 75% of the variance between the groups was explained by general cognitive deficits, especially impaired processing speed and episodic memory. Hinting Task performance of the best functioning patient group did not differ from that of the control group. When the psychosis group was divided according to diagnosis, the Hinting Task difference between individuals with schizophrenia and controls remained significant even when general cognitive performance was controlled for, suggesting specific verbal ToM deficits in schizophrenia. In contrast, those with other psychotic disorders did not differ from controls. Our results suggest that ToM deficits can be seen in early phases of psychotic disorders, schizophrenia in particular, and are partly independent of other cognitive functions. PMID- 29573660 TI - Development, validation and cultural-adaptation of the knowledge about psychosis questionnaire for African-Caribbean people in the UK. AB - The absence of assessment tools incorporating different cultural models of mental illness is a major barrier to recruiting ethnic minorities into clinical trials, reducing generalisability of findings and potentially increasing disparities in access to evidence-based care. This study aimed to develop and validate a new Knowledge about Psychosis (KAP) self-report measure and a culturally-adapted version for African-Caribbean people (CaKAP). Content and face validity were achieved through consultations with experts in psychosis and a focus group with service users, carers, and community members. Eighty-seven predominantly White British participants and 79 African-Caribbean participants completed the knowledge questionnaires (KAP and CaKAP) and measures of help-seeking and stigma. Overall, the measures showed good internal consistency and test re-test reliability. Construct validity was evidenced via significant positive associations between knowledge about psychosis and help-seeking and significant negative associations between knowledge and stigma. These measures could improve the delivery of psychosocial interventions and outcome measurement in research trials. PMID- 29573659 TI - Evaluating the genetic susceptibility to peer reported bullying behaviors. AB - Bullying is a significant public health concern with lasting impacts on youth. Although environmental risk factors for bullying have been well-characterized, genetic influences on bullying are not well understood. This study explored the role of genetics on early childhood bullying behavior. Participants were 561 children who participated in a longitudinal randomized control trial of a preventive intervention beginning in first grade who were present for the first grade peer nominations used to measure early childhood bullying and who provided genetic data during the age 19-21 year follow-up in the form of blood or saliva. Measures included a polygenic risk score (PRS) derived from a conduct disorder genome wide association study. Latent profile analysis identified three profiles of bullying behaviors during early childhood. Results suggest that the PRS was significantly associated with class membership, with individuals in the moderate bully-victim profile having the highest levels of the PRS and those in the high bully-victim profile having the lowest levels. This line of research has important implications for understanding genetic vulnerability to bullying in early childhood. PMID- 29573661 TI - Expression patterns and role of SDF-1/CXCR4 axis in boar spermatogonial stem cells. AB - The signaling of chemokine stromal cell-derived factor (SDF)-1 and its receptor C X-C motif chemokine receptor 4 (CXCR4) is involved in the cellular proliferation, survival, and migration of various cell types. Although SDF-1/CXCR4 has been implicated in the maintenance of the spermatogonial population during mouse testis development, their expression patterns and functions in boar testis remain unclear. In the present study, the expression pattern of SDF-1 and CXCR4 was determined during pre-pubertal and post-pubertal stage boar testes and in vitro cultured porcine spermatogonial stem cells (pSSCs). The role of these proteins in colony formation in cultured pSSCs was also investigated. Interestingly, SDF-1 expression was observed in PGP 9.5-positve spermatogonia in all developing stages of boar testis; however, CXCR4 expression was only detected in spermatogonia from 5-day-old boar testis. In addition, SDF-1 and CXCR4 expression was observed in cultured pSSCs from 5-day-old boar testes, and inhibition of the CXCR4 receptor signaling pathway by AMD3100 significantly decreased the colony formation of pSSCs. These results suggest that SDF-1 and CXCR4 are useful markers for detecting stage-specific spermatogonia in boar testis. Our results reveal the role of the SDF-1/CXCR4 axis in pSSC in vitro culture. PMID- 29573662 TI - Interferon-tau regulates prostaglandin release in goat endometrial stromal cells via JAB1 - unfolded protein response pathway. AB - Prostaglandins (PGs) are major products of the uterine endometrium, and they are critical for recognition of pregnancy in ruminants. During the peri-implantation period of pregnancy, interferon tau (IFN-tau) plays an important role in the regulation of endometrial PGs synthesis, but the underlying mechanisms remain poorly understood. In this work, the results demonstrated that IFN-tau increased the PGE2/PGF2alpha ratio, up-regulated the expression of JAB1 and activated the unfolded protein response (UPR). Knockdown of JAB1 reduced the PGE2/PGF2alpha ratio and inhibited the expression of UPR markers in endometrial stromal cells (ESCs) under IFN-tau treatment. Pre-treatment with endoplasmic reticulum (ER) stress activator thapsigargin (Tg) activated UPR and restored the PGE2/PGF2alpha ratio in shJAB1 groups under IFN-tau treatment. In conclusion, our results indicated that IFN-tau regulated the PGE2/PGF2alpha ratio via cooperation between JAB1 and UPR, and the reduction of JAB1 led to the down-regulation of the PGE2/PGF2alpha ratio, which inhibits UPR, and thus is harmful to early pregnancy. Activation of UPR could restore JAB1 reduction, resulting in a reduced PGE2/PGF2alpha ratio. These findings extend our understanding and may provide new insights into the mechanism of IFN-tau regulation of PG secretion in ESCs and the biological functions of JAB1 and UPR. PMID- 29573663 TI - Capsaicin protects against testicular torsion injury through mTOR-dependent mechanism. AB - SCOPE: Testicular torsion and subsequent release of reactive oxygen species (ROS) can cause infertility in adults. Oxidative stress following testicular torsion plays an important role in the yonset and development of apoptotic cell death through dysregulation of the cellular signaling pathways. Anti-inflammatory and antioxidant properties of capsaicin, a bioactive composition present in red peppers, has already been exploited for treatment of the cancer and pain relief. In present work, we evaluated the role of the mammalian target of rapamycin (mTOR) in antioxidant effect of capsaicin against reperfusion injury following testicular torsion. METHODS: Male Wistar rats weighing 200-220 g were randomly assigned into four major groups: (i) a sham operated group, (ii) a testicular torsion (TT) group, (iii) three groups treated with different doses of capsaicin (TT + 100, 500 and 1000 MUg/ml Cap), and (iv) three groups of healthy rats treated with different doses of capsaicin (100, 500 and 1000 MUg/ml). Western blotting assay was used to examine the anti-apoptotic effects of capsaicin in testicular cells following torsion. H&E and TUNEL methods were used to evaluate testicular morphology and apoptosis activity. RESULTS: Compared to control group, phosphorylation of mTOR was significantly increased in the TT groups. Capsaicin administration remarkably decreased the phosphorylation of mTOR at the highest dose (P < 0.05). Capsaicin decreased apoptosis and preserved tubular morphology in testes. CONCLUSION: Our results showed that antioxidant properties of capsaicin minimizes cell death and reperfusion injury following testicular torsion. PMID- 29573664 TI - MARCH2 is upregulated in HIV-1 infection and inhibits HIV-1 production through envelope protein translocation or degradation. AB - MARCH2 is one of the MARCH family E3 ligases, which contains eleven members that play pivotal roles in controlling the turn-over of membrane proteins, such as MHC class I, MHC class II, and cell surface receptors. In this study, we found the expression of MARCH2 to be upregulated upon HIV-1 infection. MARCH2 inhibits the production and infection of HIV-1 through ligase activity-dependent envelope protein degradation and/or intracellular retention, a mechanism shared by MARCH8 that also leads to the inhibition of HIV-1 infection. Nevertheless, unlike MARCH8 and other MARCH proteins whose transcription levels are unrelated to viral infection, the expression level of MARCH2 is markedly upregulated upon HIV-1 infection, conferring MARCH2 a unique role in monitoring and regulating the HIV-1 infection-associated process. PMID- 29573665 TI - Outcomes of single versus double hormone receptor-positive breast cancer. A GEICAM/9906 sub-study. AB - BACKGROUND: Retrospective data suggest better outcomes for patients with double hormonal receptor (oestrogen [ER] and progesterone receptor [PgR])-positive (dHR+) early breast cancer, compared with single hormonal receptor-positive, sHR+, (ER+/PgR- or ER-/PgR+) disease. Here, we evaluate the classification according to intrinsic subtypes and clinical outcomes of sHR+ versus dHR+ in HER2 negative breast cancer patients enrolled in GEICAM/9906 study (NCT00129922). METHODS: Archival tumours were retrieved retrospectively for the analysis of ER, PgR and HER2 status and classified into intrinsic subtypes using the PAM50 gene expression assay. Disease-free survival (DFS) and overall survival (OS) were explored using a Cox proportional hazard analysis. RESULTS: Data on intrinsic subtypes were available in 571 (50%) patients with ER+ and/or PR+, and HER2 negative primary tumours. The incidence of luminal A and luminal B subtypes were 52%/36% in dHR+ tumours (ER+/PgR+), and 15%/58% in ER+/PgR-tumours. ER-/PgR+ tumours were mainly luminal A (52%). Compared with ER+/PgR+ patients, DFS was similar in ER-/PgR+ (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.57 2.34, p = 0.70) but worse in ER+/PgR- patients (HR 1.60, 95% CI 1.12-2.28, p < 0.01). Similar results were observed for OS (HR 1.50, p = 0.30 and HR 1.86, p < 0.01, respectively). CONCLUSIONS: The ER+/PgR- group is characterised by higher proliferation and worse outcomes. In spite of the ER-/PgR+ subgroup resembles ER+/PgR+ disease in terms of molecular subtypes and outcomes, the small number of patients in this subgroup prevents from drawing any conclusions.

AB - BACKGROUND: Variations in foot posture, such as pes planus (low medial longitudinal arch) or pes cavus (high medial longitudinal arch) are associated with some lower limb injuries. However, the mechanism that links foot posture to injury is not clear. Research question The aim of this study was to compare plantar pressure between healthy individuals with normal, planus or cavus feet. METHODS: Ninety-two healthy volunteers (aged 18 to 45) were classified as either normal (n = 35), pes planus (n = 31) or pes cavus (n = 26) based on the Foot Posture Index, Arch Index and normalised navicular height truncated. Barefoot walking trials were conducted using an emed(r)-x400 plantar pressure system (Novel GmbH, Munich, Germany). An 11 region mask was used that included the medial heel, lateral heel, midfoot, 1st, 2nd, 3rd, 4th and 5th metatarsophalangeal joints, hallux, 2nd toe, and the 3rd, 4th and 5th toes. Peak pressure, pressure-time integral, maximum force, force-time integral and contact area were calculated for each region. One way analyses of variance and effect sizes were used to compare the three foot posture groups. RESULTS: Overall, the largest differences were between the planus and cavus foot groups in forefoot pressure and force. In particular, peak pressures at the 4th and 5th MTPJs in the planus foot group were lower compared to the normal and cavus foot groups, and displayed the largest effect sizes. Significance This study confirms that foot posture does influence plantar pressures, and that each foot posture classification displays unique plantar pressure characteristics.

AB - Many glycaemic variability (GV) indices extracted from continuous glucose monitoring systems data have been proposed for the characterisation of various aspects of glucose concentration profile dynamics in both healthy and non-healthy individuals. However, the inter-index correlations have made it difficult to reach a consensus regarding the best applications or a subset of indices for clinical scenarios, such as distinguishing subjects according to diabetes progression stage. Recently, a logistic regression-based method was used to address the basic problem of differentiating between healthy subjects and those affected by impaired glucose tolerance (IGT) or type 2 diabetes (T2D) in a pool of 25 GV-based indices. Whereas healthy subjects were classified accurately, the distinction between patients with IGT and T2D remained critical. In the present work, by using a dataset of CGM time-series collected in 62 subjects, we developed a polynomial-kernel support vector machine-based approach and demonstrated the ability to distinguish between subjects affected by IGT and T2D based on a pool of 37 GV indices complemented by four basic parameters-age, sex, BMI, and waist circumference-with an accuracy of 87.1%.

AB - Three-part white blood cell differentials which are key to routine blood workups are typically performed in centralized laboratories on conventional hematology analyzers operated by highly trained staff. With the trend of developing miniaturized blood analysis tool for point-of-need in order to accelerate turnaround times and move routine blood testing away from centralized facilities on the rise, our group has developed a highly miniaturized holographic imaging system for generating lens-free images of white blood cells in suspension. Analysis and classification of its output data, constitutes the final crucial step ensuring appropriate accuracy of the system. In this work, we implement reference holographic images of single white blood cells in suspension, in order to establish an accurate ground truth to increase classification accuracy. We also automate the entire workflow for analyzing the output and demonstrate clear improvement in the accuracy of the 3-part classification. High-dimensional optical and morphological features are extracted from reconstructed digital holograms of single cells using the ground-truth images and advanced machine learning algorithms are investigated and implemented to obtain 99% classification accuracy. Representative features of the three white blood cell subtypes are selected and give comparable results, with a focus on rapid cell recognition and decreased computational cost. PMID- 29573669 TI - The effect of a tactile-to-visual shift on young children's tendency to map novel labels onto novel objects. AB - When taught a label for an object and then asked whether an exemplar of that object or a novel object is the referent of a novel label, children favor the novel object. Preschool-aged children tend not to show this so-called disambiguation effect, however, when the test objects are presented in a different sense modality than the original object. The current experiments used a touch-to-vision paradigm to test two explanations for this unexpected pattern. Experiment 1 asked whether children might fail to retrieve the original label and found that additional label training benefitted 3-year-olds but not 4-year-olds. Experiments 2 and 3 asked whether children's reaction to discovering the cross modal match might interfere with how they process the request for the novel label and found that being allowed to share their discovery of the match benefitted 4 year-olds but not 3-year-olds. These findings support the proposal that the chief obstacle to cross-modal disambiguation changes during early childhood from difficulty in retrieving the known label to disruption caused by the discovery of the cross-modal match. PMID- 29573670 TI - Children's visual attention to emotional expressions varies with stimulus movement. AB - The majority of studies of emotion perception have relied on static isolated facial expressions. These expressions differ markedly from real-world expressions that include movement and multiple cues (e.g., bodies), leaving our understanding of how expression perception develops incomplete. We examined the looking patterns of younger children (4- and 5-year-olds), older children (8- and 9-year olds), and adults while watching dynamic video clips or static images of four different emotional expressions: happiness, sadness, anger, and fear. Expressions were presented in three conditions: face only, body only, and whole person (face and body). Children's and adults' looking patterns were affected by whether stimuli were static or dynamic and by which cues were available. Children looked to the head less for static stimuli than for dynamic stimuli, but this difference did not emerge for adults. Children and adults attended to different expression cues when presented with static images. These results demonstrate the need for increased use of dynamic stimuli in developmental studies of expression.

AB - Biofloc technology was evaluated with a view to analyse utilization of nitrogenous waste from the effluent and to improve water quality and growth parameters of Penaeus vannamei in intensive culture system. The experiment was carried out in two different treatment outdoor earthen ponds of 0.12 ha, one supplemented with carbon source (molasses, wheat and sugar) for biofloc formation and other was feed based control pond with a stocking density of 60 animals m-2 in duplicate for 120 days. Water, sediment and P. vannamei were sampled at regular intervals from the both set of ponds for evaluating physico-chemical parameters, nitrogen content and growth parameters, respectively. A significant reduction in the concentration of total ammonia nitrogen (TAN) and nitrite (NO2 N) were found in the biofloc pond than that of control pond. A significant low level of nitrogen was recorded in the effluents of biofloc pond in comparison to the control. In biofloc system, a significantly elevated heterotrophic bacterial count along with reduction in total Vibrio count was noticed. A significant improvement in the feed conversion efficiency (FCR) and growth parameters of P. vannamei was noticed in the biofloc pond. Growth of P. vannamei in the biofloc pond showed positive allometric pattern with an increased survival. The microbial biomass grown in biofloc consumes toxic inorganic nitrogen and converts it into useful protein, making it available for the cultured shrimp. This improved FCR and reduced the discharge of nitrogenous waste into adjacent environment, making intensive shrimp farming an eco-friendly enterprise. PMID- 29573672 TI - Degradation of 4-chlorophenol and microbial diversity in soil inoculated with single Pseudomonas sp. CF600 and Stenotrophomonas maltophilia KB2. AB - Soil contamination with chlorophenols is a serious problem all over the world due to their common use in different branches of industry and agriculture. The objective of this study was to determine whether bioaugmenting soil with single Pseudomonas sp. CF600 and Stenotrophomonas maltophilia KB2 and additional carbon sources such as phenol (P) and sodium benzoate (SB) could enhance the degradation of 4-chlorophenol (4-CP). During the degradation experiment, the number of bacteria as well as the structural and functional diversity of the soil microbial communities were determined. It was found that the most effective degradation of 4-CP in the soil was observed after it was inoculated with CF600 and the addition of SB. The biodegradation of five doses of 4-CP in this soil proceeded within 100 days. At the same time, the rate of the disappearance of 4-CP in the soil that had been bioaugmented with CF600 and contaminated with 4-CP and P was 5-6.5 times lower compared to its rate of disappearance in the soil that had been contaminated with 4-CP. The biodegradation of 4-CP in all of the treated and untreated soils was accompanied by a systematic decrease in the number of heterotrophic bacteria (THB) ranging between 13 and 40%. It was also proven that the tested aromatic compounds affected the soil microbial community structure through an increase in the marker fatty acids for Gram-negative bacteria (BG-) and fungi (F). The essential changes in the patterns of the fatty acid methyl esters (FAMEs) for the polluted soil included an increase in the fatty acid saturation and hydroxy fatty acid abundance. The obtained results also indicated that the introduction of CF600 into the soil contaminated with 4-CP and SB or P caused an increase in the functional diversity of the soil microorganisms. In contrast, in the soil that had been inoculated with KB2 and in the non-inoculated soil, the addition of 4-CP and P decreased the microbial activity. In conclusion, the inoculation of both strains into contaminated soil with aromatic compounds caused irreversible changes in the functional and structural diversity of the soil microbial communities. PMID- 29573673 TI - The effect of water velocity on nitrate removal in vegetated waterways. AB - The extended networks of canals and ditches in agricultural landscapes provide high buffer capacity towards nitrogen (N) excess. Their N mitigation potential depends on several biotic and abiotic factors, among which water velocity is poorly explored and generally omitted from the parameterization of this remarkable ecosystem service. The present work reports new insights on the role of flow velocity in regulating N removal via denitrification in sediments colonized by Phragmites australis. Denitrification was investigated in outdoor mesocosms in the presence and absence of P. australis and over a small range of flow velocity (0-6 cm s-1) typical of low-gradient water bodies. Simultaneous measurements of NO3- consumption and N2 production based on analyses of N2:Ar by Membrane Inlet Mass Spectrometry were undertaken. Vegetated sediments were found more efficient in converting NO3- to N2 via microbial-mediated denitrification (27-233 mmol N m-2 d-1) than bare sediments (18-33 mmol N m-2 d-1). Vegetation provides multiple interfaces, i.e. in the rhizosphere and on epiphytic biofilms, that support the development and activity of bacterial communities responsible for NO3- dissipation. NO3- removal and denitrification rates exhibited one order of magnitude raise when water velocity passed from 0 to 6 cm s-1 in vegetated sediments. Indeed, in slow-flow vegetated waterways denitrification may be physically limited and the increase of water velocity enhances the rate of NO3- supply through the diffusive boundary layer, thereby promoting its consumption and loss from the system. Water velocity should be taken into account as a key factor for management and restoration actions aimed at maximizing the NO3- buffer capacity of low-flow drainage networks. PMID- 29573674 TI - Competing actors in the climate change arena in Mexico: A network analysis. AB - This paper analyzes the actors in the climate change arena and their influence in directing Mexico toward policies that decrease greenhouse gas emissions, such as the carbon tax and climate change law. The network analysis of the agreement of these laws and public policies in Mexico is a lesson for any country that is in the process of designing and adopting environmental laws. The research is performed using a network analysis that is derived from interviews with various main actors and a discourse analysis of the media. Results show that actors do not coordinate their efforts-they meet frequently but in different inter ministerial commissions-and do not enforce the same policies. The actors in the industry have formed strong coalitions against the carbon tax and the General Law on Climate Change, whereas international institutions have formed coalitions that support these policies and laws. PMID- 29573675 TI - Short-term effects of nanoscale Zero-Valent Iron (nZVI) and hydraulic shock during high-rate anammox wastewater treatment. AB - The stability and resilience of an anaerobic ammonium oxidation (anammox) system under transient nanoscale Zero-Valent Iron (nZVI) (50, 75 and 100 mg L-1), hydraulic shock (2-fold increase in flow rate) and their combination were studied in an up-flow anaerobic sludge blanket reactor. The response to the shock loads can be divided into three phases i.e. shock, inertial and recovery periods. The effects of the shock loads were directly proportional to the shock intensity. The effluent quality was gradually deteriorated after exposure to high nZVI level (100 mg L-1) for 2 h. The higher effluent sensitivity index and response caused by unit intensity of shock was observed under hydraulic and combined shocks. Notably, the specific anammox activity and the content of heme c were considerably reduced during the shock phase and the maximum loss rates were about 30.5% and 24.8%, respectively. Nevertheless, the extracellular polymeric substance amount in the shock phase was enhanced in varying degrees and variation tendency was disparate at all the tested shock loads. These results suggested that robustness of the anammox system was dependent on the magnitude shocks applied and the reactor resistance can be improved by reducing hydraulic retention time with the increase of nZVI concentration under these circumstances. PMID- 29573676 TI - Life cycle environmental impacts of advanced wastewater treatment techniques for removal of pharmaceuticals and personal care products (PPCPs). AB - Pharmaceutical and personal care products (PPCPs) are of increasing interest because of their ecotoxicological properties and environmental impacts. Wastewater treatment plants (WWTPs) are the main pathway for their release into freshwaters due to the inefficiency of conventional WWTPs in removing many of these contaminants from effluents. Therefore, different advanced effluent treatment techniques have been proposed for their treatment. However, it is not known at present how effective these treatment methods are and whether on a life cycle basis they cause other environmental impacts which may outweigh the benefits of the treatment. In an effort to provide an insight into this question, this paper considers life cycle environmental impacts of the following advanced treatment techniques aimed at reducing freshwater ecotoxicity potential of PPCPs: granular activated carbon (GAC), nanofiltration (NF), solar photo-Fenton (SPF) and ozonation. The results suggest that on average NF has the lowest impacts for 13 out of 18 categories considered. GAC is the best alternative for five impacts, including metals and water depletion, but it has the highest marine eutrophication. SPF and ozonation are the least sustainable for eight impacts, including ecotoxicity and climate change. GAC and NF are also more efficient in treating heavy metals while avoiding generation of harmful by-products during the treatment, thus being more suitable for potable reuse of wastewater. However, releasing the effluent without advanced treatment to agricultural land achieves a much higher reduction of freshwater ecotoxicity than treating it by any of the advanced treatments and releasing to the environment. Therefore, the use of advanced effluent treatment for agricultural purposes is not recommended. PMID- 29573677 TI - Vertical air temperature gradients under the shade of two contrasting urban tree species during different types of summer days. AB - Moderation of thermal energy balance through the canopies of urban trees is well known. However, a more functional and quantitative view of the heterogeneous urban environment and their influence on the below-canopy vertical air temperature gradients is largely missing. Throughout the summer 2016 we continuously measured air temperature at three different heights (at 1.5, 3 and 4.5m from the ground) under the canopies of two common but contrasting street tree species in respect of eco-physiology and morphology in Munich, Germany: Robinia pseudoacacia L. (ring porous) and Tilia cordata Mill. (diffuse porous). Along with air and surface temperature we also measured meteorological and edaphic variables and categorized summer time as cool, mild, summer and hot days. Global radiation, vapour pressure deficit and soil temperature increased as the days got warmer but precipitation, soil moisture and wind speed showed the reversed pattern. Overall, T. cordata trees with higher leaf area index and sap wood area provided three times more transpiration than R. pseudoacacia. On an average air temperature gradient of outside to inside canopy dropped from 1.8 degrees C to 1.3 degrees C for T. cordata but from 1.5 degrees C to only 0.5 degrees C for R. pseudoacacia as the days got warmer. Vertical decline of air cooling effect was around 1 degrees C from canopy to the near-ground (1.5m). Lower soil moisture but higher soil temperature suggested that cool air from the canopy mixed with a higher amount of sensible heat flux under the canopies of T. cordata compared to the R. pseudoacacia as the days got warmer. The study indicated a threshold for extreme hot days when grass surface evapotranspirational cooling will not be as effective and act like built surfaces rather deep shading from tree canopies will be important. PMID- 29573678 TI - Bioreceptivity index for granitic rocks used as construction material. AB - Bioreceptivity is a fundamental concept in the ornamental stone industry and in the fields of cultural heritage and civil engineering to understand the susceptibility of stone constructions to biological colonisation and subsequent biodeterioration. However, a bioreceptivity index (BI) has not yet been established for any construction material. The aim of the present study is developing a simple, robust and well-founded BI for granitic rocks. For this purpose, a standardised laboratory protocol was used to grow phototrophic biofilms on several varieties of granite. The colonisation was then assessed by chlorophyll fluorescence and colour measurements. Based on the results thus obtained, a BI including two components (BIgrowth and BIcolour) is proposed. BIgrowth quantifies the extent of the biological growth and BIcolour quantifies the colour change undergone by the stone due to the colonisation, which can be considered the bioreceptivity perceptible to the human eye. The values of BI, BIgrowth and BIcolour were fitted to a scale of 0-10, thus enabling qualitative classification of the lithotypes according to their primary bioreceptivity. Eleven varieties of granite commonly used as construction material and with a honed surface finish (one variety with three additional surface finishes: polished, sawn and sanded) were thus assigned the corresponding BI, which represents a new quality factor for the stone industry. The index can therefore be used by end-users as a decision-making tool in the selection of appropriate lithotypes for building and/or ornamental purposes. PMID- 29573679 TI - A framework to overcome barriers to green innovation in SMEs using BWM and Fuzzy TOPSIS. AB - Recent years have witnessed a significant rise in exploring the barriers which obstruct adoption of green practices by SMEs. There is a constant need to innovate in terms of products, processes, and management so that we can overcome these barriers to green practices adoption and implementation. This study employs a three-phase methodology to identify barriers and solutions to overcome these barriers to green innovation in SMEs. Through extensive literature review and the opinion of selective manager's, seven main category barriers, thirty-six sub category barriers, and twenty solutions to overcome these barriers were identified. BWM is used to rank these barriers and Fuzzy TOPSIS is used to rank solutions to overcome these barriers. Four Indian SMEs are taken to exemplify the proposed three paged model. To check the robustness of the model, a sensitivity analysis was also performed. The results of the analysis can act as a stepping stone for SME managers to eliminate and overcome barriers to green innovation in their firm and compete healthily in the market. The paper sets a framework for future studies in this area of research-work. PMID- 29573680 TI - Quantifying direct carbon dioxide emissions from wastewater treatment units by nondispersive infrared sensor (NDIR) - A pilot study. AB - Treatment of nutrient-rich wastewater potentially results in direct release of greenhouse gases (GHGs) such as CO2, N2O or CH4 - and thus affects Waste Water Treatment Plant's carbon footprint. Accurate CO2 quantification is challenging due to various chemical, physical and operational conditions. A floating chamber equipped with a nondispersive infrared, single beam, dual wavelength sensor has been evaluated for a pilot approach to quantify fugitive CO2 emissions above different wastewater treatment units. Total average CO2 flux was 1182gCO2.m-2.d-1 with minimum and maximum fluxes of 829gCO2.m-2.d-1 and 1493gCO2.m-2.d-1, respectively. Total observed CO2 emissions were in 7 to 17kgCO2.PE-1.a-1 (average 12kgCO2.PE-1.a-1). The nitrification tank accounted for about 94.3% of the emissions, followed by secondary clarification (ca. 4.3%) and denitrification (ca. 1.4%), based on those average annual CO2 emissions per population equivalent (PE). PMID- 29573681 TI - Understanding intricacies of clogging and its alleviation by introducing earthworms in soil biofilters. AB - With the scarcity of fresh water and rise in pollution load in the aquatic ecosystem over the globe, the domestic and industrial effluents need to be reused after suitable treatment. In an attempt to do so, soil biofilters have been identified as a treatment alternative that is suitable for application in developing countries. However, rapid development of clogging in the soil biofilters limits its applicability as an effective technology. This paper aims to understand the occurrence of clogging due to biofilms formation in and over the bedding of soil media. To address this, the organic loading rates (OLRs) were varied in the range of 2.25-11.25kgCOD/m3.day to create different degree of clogging. Earthworms were inoculated into the soil bedding at the earthworm densities (EWDs) of 0, 5000 and 10,000earthworms/m3 to study the effect of earthworms introduction on clogging. The degree of clogging was measured using clogging coefficient (CC), hydraulic conductivity and head loss. The study highlights the impact of earthworms on the removal performance and clogging of soil biofilter. For all earthworm densities, head loss and clogging coefficient increased and hydraulic conductivity decreased linearly with organic loading rate. Introduction of earthworms versus no earthworms resulted in lower head loss and clogging coefficient and higher hydraulic conductivity for all organic loading rates, while increasing EWD from 5000 to 10,000 had only marginal effects on all parameters. The study reveals that high organic loading rate activates higher number of microbial sites, in turn causing higher degree of clogging. However, the introduction of earthworms reduces the clogging rate significantly along with enhanced treatment performance. The outcome of this study indicates that incorporation of earthworms into the soil biofilter can reduce the degree of bio-clogging and might provide a highly sustainable, low cost and efficient treatment system for the developing countries. PMID- 29573682 TI - Enrichment of free-living amoebae in biofilms developed at upper water levels in drinking water storage towers: An inter- and intra-seasonal study. AB - Free-living amoebae (FLA) are ubiquitous organisms present in various natural and artificial environments, such as drinking water storage towers (DWST). Some FLA, such as Acanthamoeba sp., Naegleria fowleri, and Balamuthia mandrillaris, can cause severe infections at ocular or cerebral level in addition to being potential reservoirs of other pathogens. In this work, the abundance and diversity of FLA was evaluated in two sampling campaigns: one performed over five seasons in three DWST at three different levels (surface, middle and bottom) in water and biofilm using microscopy and PCR, and one based on the kinetics analysis in phase contrast and confocal microscopy of biofilm samples collected every two weeks during a 3-month period at the surface and at the bottom of a DWST. In the seasonal study, the FLA were detected in each DWST water in densities of ~20 to 25amoebaeL-1. A seasonal variation of amoeba distribution was observed in water samples, with maximal densities in summer at ~30amoebaeL-1 and minimal densities in winter at ~16amoebaeL-1. The FLA belonging to the genus Acanthamoeba were detected in two spring sampling campaigns, suggesting a possible seasonal appearance of this potentially pathogenic amoeba. Interestingly, a 1 log increase of amoebae density was observed in biofilm samples collected at the surface of all DWST compared to the middle and the bottom where FLA were at 0.1-0.2amoebae/cm2. In the kinetics study, an increase of amoebae density, total cell density, and biofilm thickness was observed as a function of time at the surface of the DWST, but not at the bottom. To our knowledge, this study describes for the first time a marked higher FLA density in biofilms collected at upper water levels in DWST, constituting a potential source of pathogenic micro-organisms. PMID- 29573683 TI - Inhibition of biofilm growth on polymer-MWCNTs composites and metal surfaces. AB - There is an increased interest in incorporating multi-wall carbon nanotubes (MWCNTs) into polymer matrices to control the adhesion of bacteria to surfaces and the subsequent formation of biofilm growth on the surface of water pipes, food packages, and medical devices. Microbial interactions with carbon nanotube polymer composites in the environment are not well understood. The growth of Pseudomonas fluorescens (gram-negative) and Mycobacterium smegmatis (gram positive) biofilms on copper, polyethylene (PE), polyvinyl chloride, and stainless steel was compared with growth on MWCNT-PE composites in order to gain insight into the effect of the surface properties of nanomaterials on the attachment and proliferation of microorganism which could result in the engineering of better, non-fouling materials. A statistical analysis of the biofilm growth showed a significant impact of materials for both P. fluorescens (p < 0.0001) and M. smegmatis (p = 0.00426). Biofilm growth after 56 days on PE compared to biofilm growth on copper surfaces decreased by 46.4% and 34.9% for P. fluorescens and M. smegmatis, respectively. Biofilm growth on PE-multiwall-carbon nanotubes (MWCNTs)-composites surface compared to PE decreased by 89.3% and 29% for P. fluorescens and M. smegmatis, respectively. Bacterial species (p < 0.0006) and surface roughness (p < 0.0001) were important factors in determining the attachment and initial biofilm growth rate. The interactions between cells and material surface could be attributed to the complicated and collective effect of electrostatic forces, hydrophobic interactions, and hydrogen/covalent bonding. Further study is needed to determine whether or not there is a difference between the cell attachment in the exponential growth phase and the stationary, or decay, phase cells.

AB - The components of petrochemical wastewater (PCWW) are very complex and it is one of the most important sources of organic micropollutants (OMPs) in water bodies. To improve the effluent qualities of PCWW, the Chinese government has promulgated a new Emission Standard of Pollutants for Petroleum Chemistry Industry. More than 60 types of OMPs, most of which are toxic organics, are added and strictly limited in the standard. Based on the bench- and pilot-scale experiments, a pretreatment (microaerobic hydrolysis and acidification, MOHA), biological (anoxic/oxic process, A/O) and advanced treatment (micro-flocculation dynasand filtration and catalytic ozonation, MFDF-CO) integrated process is proposed. The full-scale application in the Chinese biggest petrochemical wastewater treatment plant has demonstrated that the performance of the integrated process is stable and it can significantly improve the effluent qualities. The effluent COD decreased from 84.7 to 47.0mg/L and most of the OMPs were removed. The EC50 of the effluent for luminescent bacteria assay, algal growth inhibition, Daphnia magna inhibition test and zebrafish eggs test are all higher than 100% and the induction rate (IR) for genotoxicity is only 0.76. The energy demand, however, with the electricity consumption increase by 44.1%, is very high for OMPs removal, leading to high indirect carbon emission. PMID- 29573686 TI - Experimental and theoretical analyses on the impacts of ionic surfactants on sludge properties. AB - A large amount of excess waste activated sludge is produced in municipal wastewater treatment plants and should be further disposed to avoid environmental pollution. Ionic surfactants are being widely used for sludge conditioning, but how and to what extent ionic surfactants change the sludge properties remain unclear. In this work, the impacts of two typical ionic surfactants on the flocculability and stability of sludge were investigated by using experimental and theoretical analyses. The treatment of anionic sodium dodecyl sulfate (SDS) resulted in more detachment of extracellular materials and fluorophores from sludge compared to the treatment of cationic trimethyl ammonium bromide (DTAB). Fourier transform infrared spectra analysis indicates the promoted release of proteins and polysaccharides induced by the surfactants. Deteriorated flocculability of sludge was observed for the SDS-treated sludge, while treatment of DTAB slightly affected the overall sludge flocculability. The sludge floc structure became less stable after treatments of both surfactants, as confirmed by the elevated dispersed mass concentration of small particles in shearing tests. The relationship between the content of extracellular polymeric substances, surfactant dose and sludge properties were evaluated and the roles of released extracellular polymeric substances and surfactant dose in affecting sludge flocculability were examined. Extended DLVO approach was adopted to explore the stability of sludge. By using such an integrated approach, the impacts of ionic surfactants on sludge flocculability and stability were revealed, which is useful in understanding the mechanisms of sludge conditioning by surfactant treatment. PMID- 29573687 TI - Remediation techniques for heavy metal-contaminated soils: Principles and applicability. AB - Globally there are over 20millionha of land contaminated by the heavy metal(loid)s As, Cd, Cr, Hg, Pb, Co, Cu, Ni, Zn, and Se, with the present soil concentrations higher than the geo-baseline or regulatory levels. In-situ and ex situ remediation techniques have been developed to rectify the heavy metal contaminated sites, including surface capping, encapsulation, landfilling, soil flushing, soil washing, electrokinetic extraction, stabilization, solidification, vitrification, phytoremediation, and bioremediation. These remediation techniques employ containment, extraction/removal, and immobilization mechanisms to reduce the contamination effects through physical, chemical, biological, electrical, and thermal remedy processes. These techniques demonstrate specific advantages, disadvantages, and applicability. In general, in-situ soil remediation is more cost-effective than ex-situ treatment, and contaminant removal/extraction is more favorable than immobilization and containment. Among the available soil remediation techniques, electrokinetic extraction, chemical stabilization, and phytoremediation are at the development stage, while the others have been practiced at full, field scales. Comprehensive assessment indicates that chemical stabilization serves as a temporary soil remediation technique, phytoremediation needs improvement in efficiency, surface capping and landfilling are applicable to small, serious-contamination sites, while solidification and vitrification are the last remediation option. The cost and duration of soil remediation are technique-dependent and site-specific, up to $500ton-1 soil (or $1500m-3 soil or $100m-2 land) and 15years. Treatability studies are crucial to selecting feasible techniques for a soil remediation project, with considerations of the type and degree of contamination, remediation goals, site characteristics, cost effectiveness, implementation time, and public acceptability. PMID- 29573688 TI - Coupling hydrological modeling and support vector regression to model hydropeaking in alpine catchments. AB - Water management in the alpine region has an important impact on streamflow. In particular, hydropower production is known to cause hydropeaking i.e., sudden fluctuations in river stage caused by the release or storage of water in artificial reservoirs. Modeling hydropeaking with hydrological models, such as the Soil Water Assessment Tool (SWAT), requires knowledge of reservoir management rules. These data are often not available since they are sensitive information belonging to hydropower production companies. In this short communication, we propose to couple the results of a calibrated hydrological model with a machine learning method to reproduce hydropeaking without requiring the knowledge of the actual reservoir management operation. We trained a support vector machine (SVM) with SWAT model outputs, the day of the week and the energy price. We tested the model for the Upper Adige river basin in North-East Italy. A wavelet analysis showed that energy price has a significant influence on river discharge, and a wavelet coherence analysis demonstrated the improved performance of the SVM model in comparison to the SWAT model alone. The SVM model was also able to capture the fluctuations in streamflow caused by hydropeaking when both energy price and river discharge displayed a complex temporal dynamic.

AB - Cancer has become the primary reason of deaths in Dilovasi probably due to its location with unique topography under the influence of heavy industrialization and traffic. In this study, possible sources and carcinogenic health risks of PAHs and PCBs were investigated in Dilovasi region by Positive Matrix Factorization (PMF) and the USEPA approach, respectively. PAHs and PCBs were measured monthly for a whole year at 23 sampling sites using PUF disk passive samplers. Average ambient air concentrations were found as 285+/-431ng/m3 and 4152+/-6072pg/m3, for Sigma15PAH and Sigma41PCB, respectively. PAH concentrations increased with decreasing temperature especially at urban sites, indicating the impact of residential heating in addition to industrial activities and traffic. On the other hand, PCB concentrations mostly increased with temperature probably due to enhanced volatilization from their sources. Possible sources of PAHs were found as emissions of diesel and gasoline vehicles, biomass and coal combustion, iron and steel industry, and unburned petroleum/petroleum products, whereas iron steel production, coal and biomass burning, technical PCB mixtures, and industrial emissions were identified for PCBs. The mean carcinogenic risk associated with inhalation exposure to PAHs and PCBs were estimated to be >10-6 and >10-5, respectively, at all sampling points, while the 95th percentile was >10-5 at 15 of 23 and >10-4 at 8 of 23 sampling locations, respectively. Probabilistic assessment showed, especially for PCBs, that a majority of Dilovasi population face significant health risks. The higher risks due to PCBs further indicated that PCBs and possibly other pollutants originating from the same sources such as PBDEs and PCNs may be an important issue for the region.

AB - Lake Urmia (LU) once was the second largest hypersaline lake in the world, covering up to 6000km2, but has undergone catastrophic desiccation in recent years resulting in loss of 90% of its area and extensive coverage by playas and marshlands that represent a source of salt and dust. This study examines daily Aerosol Optical Depth (AOD) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) between 2001 and 2015 over northwestern Iran, which encompasses LU. Intriguingly, salt emissions from the LU surface associated with ongoing desiccation do not drive the study region's AOD profile, whereas pollution transported from other regions and emissions around LU are more important. Signatures of increasing local crustal emissions are most evident outside of the peak dust season (January, February, and October) and on the periphery of LU. AOD has generally increased in the latter half of the study period with the onset of the AOD ramp-up starting a month earlier in the spring season when comparing 2009-2015 versus earlier years. Results indicate that suppression of emissions on the LU border is critical as the combined area of salt and salty soil bodies around LU have increased by two orders of magnitude in the past two decades, and disturbing these areas via activities such as grazing and salt harvesting on the lake surface can have more detrimental impacts on regional pollution as compared to benefits. These results have important implications for public health, climate, the hydrological cycle, and pollution control efforts.

AB - Yacuambi river waters (southeast Ecuador, Amazonian region) were assessed to evaluate the potential risk to populations, who use it for drinking and irrigation, and ecosystems, which are part of Tropical Andes hotspot and considered some of the most biodiverse in the world. The water quality index was calculated and some quality parameters were checked to comply with Ecuadorian and North American standards for human consumption, preservation of aquatic life and irrigation. Four samplings were carried out in six stations covering the entire length of the Yacuambi river. Several parameters were analyzed: pH, conductivity, dissolved oxygen, temperature, color, phosphates, nitrite, nitrate, biochemical oxygen demand, chemical oxygen demand, total solids, turbidity, metals (Ba, Cd, Cr, Pb, As and Hg), pesticides and fecal coliforms. The water quality in the Yacuambi river was good and medium according to the classification of the Water Quality Index. However, it was unsuitable for human consumption, preservation of aquatic life and irrigation according to Ecuadorian and North American standards. Arsenic, color and fecal coliforms exceeded the limits for human consumption in all samples tested. Thresholds of preservation of aquatic life were exceeded in all samples in the case of Pb and in some samples for As, pH, nitrite and nitrate. Arsenic and fecal coliforms made Yacuambi river waters unsuitable for irrigation. PMID- 29573692 TI - Long-term trends in submicron particle concentrations in a metropolitan area of the northeastern United States. AB - Significant changes in emission sources have occurred in the northeastern United States over the past decade, due in part to the implementation of emissions standards, the introduction and addition of abatement technologies for road transport, changes in fuel sulfur content for road and non-road transport, as well as economic impacts of a major recession and differential fuel prices. These changes in emission scenarios likely affected the concentrations of airborne submicron particles. This study investigated the characteristics of 11-500nm particle number concentrations and their size spectra in Rochester, NY during the past 15years (2002 to 2016). The modal structure, diurnal, weekly and monthly patterns of particle number concentrations are analyzed. Long-term trends are quantified using seasonal-trend decomposition procedures based on "Loess", Mann Kendall regression with Theil-Sen slope and piecewise regression. Particle concentrations underwent significant (p<0.05) downward trends. An annual decrease of -323particles/cm3/y (-4.6%/y) was estimated for the total particle number concentration using Theil-Sen analysis. The trends were driven mainly by the decrease in particles in the 11-50nm range (-181particles/cm3/y; -4.7%/y). Slope changes were investigated annually and seasonally. Piecewise regression found different slopes for different portions of the overall period with the strongest declines between 2005 and 2011/2013, followed by small upward trends between 2013 and 2016 for most size bins, possibly representing increased vehicular traffic after the recovery from the 2008 recession.

AB - The handling of sewage sludge (SS) and urban plant litter (UPL) has become an important concern. Immobilizing heavy metals (HMs) is regarded as a necessary process for recycling SS in agriculture and forestry. Here, HM removal and HM phytotoxicity in SS during vermicomposting with different additive UPLs was investigated. The results show that vermicomposting with additive UPL significantly reduced the content of HMs, and increased organic carbon content and the proportion of macroaggregates in SS. This process also significantly immobilized HMs by mainly transforming extractable and reducible HMs into residual products. The litters of Dracontomelon duperreanum and Bauhinia purpurea increased oxidizable HMs in SS and the accumulation capacity of HMs of earthworms during vermicomposting. The Cd content in vermicomposts with the B. purpurea litter addition was decreased by 31% relative to the initial SS. Maize in vermicomposts with UPL additions, especially with B. purpurea litter, exhibited significan5tly higher seed germination rates, seedling biomass, root activity, and a lower accumulation of HMs than in SS compost without UPL additions. These results suggest that vermicomposting with additive UPL can alleviate the phytotoxicity of HMs in SS and provides a new method for simultaneously recycling SS and UPL.

AB - The dissolved organic matter (DOM) and nutrient dynamics in small mountainous rivers (SMRs) strongly depend on hydrologic conditions, and especially on extreme events. Here, we investigated the quantity and quality of DOM and inorganic nutrients during base-flow and typhoon events, in a chronically N-saturated mainstream and low N-loaded tributaries of a forested small mountainous reservoir catchment in Taiwan. Our results suggest that divergent transport mechanisms were triggered in the mainstream vs. tributaries during typhoons. The mainstream DON increased from 3.4 to 34.7% of the TDN pool with a static DOC:NO3-N ratio and enhanced DOM freshness, signalling a N-enriched DOM transport. Conversely, DON decreased from 46 to 6% of the TDN pool in the tributaries and was coupled with a rapid increase of the DOC:NO3-N ratio and humified DOM signals, suggesting the DON and DOC were passively and simultaneously transported. This study confirmed hydrology and spatial dimensions being the main drivers shaping the composition and concentration of DOM and inorganic nutrients in small mountainous catchments subject to hydrologic extremes. We highlighted that the dominant flow paths largely controlled the N-saturation status and DOM composition within each sub catchment, the effect of land-use could therefore be obscured. Furthermore, N saturation status and DOM composition are not only a result of hydrologic dynamics, but potential agents modifying the transport mechanism of solutes export from fluvial systems. We emphasize the importance of viewing elemental dynamics from the perspective of a terrestrial-aquatic continuum; and of taking hydrologic phases and individual catchment characteristics into account in water quality management.

AB - Recent evidence indicated that methylmercury (MeHg) contaminated rice can be a significant source of MeHg human exposure, but the health implications are not known. The objective of this study was to study the kinetics, speciation, and effects of MeHg contaminated rice using a rat model. Five groups of adult Sprague Dawley rats (n=10 in each group) were fed control rice, low (10ng/g MeHg) and high (25ng/g MeHg) MeHg contaminated rice. Two groups of the positive control were fed control rice spiked with the same levels of MeHgCl. Short-term exposure to low level of spiked MeHgCl stimulated the growth of male rats while long-term exposure to spiked MeHgCl inhibited the growth in female rats. There was no temporal variation of total mercury (THg) concentrations in the rat fecal samples from each group, and the THg concentrations significantly correlated with the inorganic Hg concentrations in the feeding rice. There were significant differences in the accumulation of THg and MeHg among different groups and different organs. THg and MeHg concentrations in the kidney were the highest among the organs examined. The blood and brain had high percentages of THg as MeHg, which indicates that MeHg can easily pass through the blood-brain barrier and has a high affinity for brain tissue. Exposure to rice containing 25ng/g MeHg decreased antioxidant function and damaged the nervous system in rats, but no significant effects were found in the group fed with rice containing 10ng/g MeHg. MeHgCys in rice is less toxic than spiked MeHgCl to rats. The toxicity of MeHg both decided by its concentration and speciation.

AB - Omega-3 (n-3) fatty acids modulate epigenetic changes critical to genesis and differentiation of neural cells. Conversely, maternal protein-malnutrition can negatively modify these changes. This study investigated whether a low n-6/n-3 ratio in a maternal diet could favor histone-3 (H3) modifications, gene transcription and differentiation in the offspring neural cells even under protein-deficiency. Female rats fed a control (Ct), or 3 types of multideficient diets differing in protein levels or linoleic/alpha-linolenic fatty acid ratios (RBD, RBD-C, RBD-SO) from 30 days prior to mating and during pregnancy. Cerebral cortex tissue and cortical cultures of progeny embryonic neurons and postnatal astrocytes were analyzed. H3K9 acetylation and H3K27 or H3K4 di-methylation levels were assessed by flow cytometry and/or immunocytochemistry. In astrocyte cultures and cortical tissue, the GFAP protein levels were assessed. Glial derived neurotrophic factor (GDNF) and leukemia inhibitory factor (LIF) gene expression were evaluated in the cortical tissue. GFAP levels were similar in astrocytes of Ct, RBD and RBD-C, but 65% lower in RBD-SO group. Higher levels of H3K9Ac were found in the neurons and H3K4Me2 in the astrocytes of the RBD group. No intergroup difference in the cortical GDNF mRNA expression or the H3K27Me2 levels in astrocytes was detected. LIF mRNA levels were higher in the RDB (P=.002) or RBD-C (P=.004) groups than in the control. The findings indicate the importance of dietary n-3 availability for the brain, even under a protein deficient condition, inducing Histone modifications and increasing LIF gene transcription, involved in neural cell differentiation and reactivity. PMID- 29573697 TI - Changes in total knee arthroplasty design affect in-vivo kinematics in a redesigned total knee system: A fluoroscopy study. AB - BACKGROUND: Journey II Bi-Cruciate-Stabilized knee system was designed to overcome the complications of Journey Bi-Cruciate-Stabilized, including ilio tibial band inflammation and episodes of dislocation. The purpose of this study was to assess differences in knee kinematics between the first and second generation design by means of video-fluoroscopy. Re-designed prosthesis in-vivo kinematics was analyzed during activities of daily living and results were eventually compared with those of the previous system, as reported in a previously published study. It was hypothesized that changes in components' design influences replaced knee's kinematic patterns. METHODS: Sixteen patients (3 males, 13 females) implanted with the redesigned prosthesis were assessed by video-fluoroscopy during stair-climbing, chair-rising and leg-extension at 8 months of follow-up. Patterns of axial rotation and antero-posterior motion of the medial and lateral femoral condyles were obtained. Range of Motion and International Knee Society Score were recorded pre- and post-operatively. Student t-tests were applied to compare the mean of each interesting variables. FINDINGS: The comparison of the kinematics of the two designs revealed similar patterns of axial rotation, with progressive femoral external rotation in flexion and reduced absolute values of displacement for the new system. Reduced posterior displacements of the medial and lateral condyles were observed in Journey II patients. In terms of absolute location, the lateral condyle in the redesigned prosthesis showed a more anterior position on the tibial-baseplate embedded coordinate system at maximal flexion. INTERPRETATION: Design changes in the recently-introduced total knee system contributed to modify its in-vivo knee kinematics as demonstrated by video-fluoroscopy.

AB - In this work, underdetermined blind decomposition method is developed to recognize individual components from the three-way fluorescent spectra of their mixtures by using sparse component analysis (SCA). The mixing matrix is estimated from the mixtures using fuzzy data clustering algorithm together with the scatters corresponding to local energy maximum value in the time-frequency domain, and the spectra of object components are recovered by pseudo inverse technique. As an example, using this method three and four pure components spectra can be blindly extracted from two samples of their mixture, with similarities between resolved and reference spectra all above 0.80. This work opens a new and effective path to realize monitoring PAHs in water by three-way fluorescence spectroscopy technique. PMID- 29573699 TI - Spectral and physicochemical properties of difluoroboranyls containing N,N dimethylamino group studied by solvatochromic methods. AB - The solvatochromism of the dyes was analyzed based on the four-parameter scale including: polarizability (SP), dipolarity (SdP), acidity (SA) and basicity (SB) parameters by method proposed by Catalan. The change of solvent to more polar caused the red shift of absorption and fluorescence band position. The frequency shifts manifest the change in the dipole moment upon excitation. The ground-state dipole moment of the difluoroboranyls was estimated based on changes in molecular polarization with temperature. Moreover, the Stokes shifts were used to calculate the excited state dipole moments of the dyes. For the calculation, the ground state dipole moments and Onsager cavity radius were also determined theoretically using density functional theory (DFT). The experimentally determined excited state dipole moments for the compounds are higher than the corresponding ground state values. The increase in the dipole moment is described in terms of the nature of the excited state.

AB - Development of a technically simple yet effective method for paraquat (PQ) detection is of great importance due to its high clinical and environmental relevance. In this study, we developed a pyranine-based fluorescent "turn-off" method for PQ sensing based on pyranine-PQ interaction. We investigated the dependence of analytical performance of this method on the experimental conditions, such as the ion strength, medium pH, and so on. Under the optimized conditions, the method is sensitive and selective, and could be used for PQ detection in real-world sample. This study essentially provides a readily accessible fluorescent system for PQ sensing which is cheap, robust, and technically simple, and it is envisaged to find more interesting clinical and environmental applications. PMID- 29573701 TI - Behavioral evidence suggestive of frontal lobe pathology in the amnesic H.M. AB - From the earliest published reports, Henry Gustav Molaison-who until his death in 2008 was known simply by his initials H.M.-was characterized as having a profound anterograde amnesia subsequent to mid temporal lobe resection, and that this amnestic condition was uncomplicated by other cognitive or behavioral impairments. Post-mortem neuropathological examination has detected-in addition to the expected temporal lobe lesions-previously unreported frontal lobe and white matter pathology, inviting questions concerning the behavioral and cognitive consequences that might result from such lesions. The purpose of this article is to recount published descriptions of a range of anomalous behaviors by H.M. that can not be explained by the memory impairments typically associated with anterograde amnesia, to counter previous claims that these behaviors are attributable to amygdalar damage, and to advance the interpretation that these behaviors are instead consistent with well-documented effects of frontal lobe pathology. Transcripts of interviews with H.M. which feature disjointed, often contradictory, and arguably confabulatory responses are presented in support of this argument. PMID- 29573702 TI - Changes in brain connectivity following exposure to bilateral eye movements. AB - The present research assessed how engaging in bilateral eye movements influences brain activity. Participants had their resting-state brain activity recorded with electroencephalography (EEG) before and after they performed 30 s of bilateral eye movements or a center-control manipulation. We assessed differences in change scores for absolute power and coherence between the eye-movement and center control conditions. A main effect for handedness was present for EEG power in the theta and beta frequency bands, with inconsistent-handed participants displaying a greater increase than consistent-handed participants in both frequency bands. For theta, the increase in power for inconsistent handers was specific to participants in the bilateral eye-movement condition, whose increase in theta power exceeded the increase in theta power for consistent-handed participants regardless of condition. In contrast, for coherence, a main effect for condition was present for the delta frequency band, with participants in the control condition exhibiting a significant drop in posterior delta coherence pre to post. We suggest that the maintenance of posterior delta coherence over time may be an important factor in sustaining attention. Further, the malleability of EEG power for inconsistent-handed participants reveals the importance of individual differences variables in the potential for behavioral manipulations to change brain activity. PMID- 29573703 TI - N-acetyl cysteine reverts the proinflammatory state induced by cigarette smoke extract in lung Calu-3 cells. AB - Chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF) are lethal pulmonary diseases. Cigarette consumption is the main cause for development of COPD, while CF is produced by mutations in the CFTR gene. Although these diseases have a different etiology, both share a CFTR activity impairment and proinflammatory state even under sterile conditions. The aim of this work was to study the extent of the protective effect of the antioxidant N-acetylcysteine (NAC) over the proinflammatory state (IL-6 and IL-8), oxidative stress (reactive oxygen species, ROS), and CFTR levels, caused by Cigarette Smoke Extract (CSE) in Calu-3 airway epithelial cells. CSE treatment (100 ug/ml during 24 h) decreased CFTR mRNA expression and activity, and increased the release of IL-6 and IL-8. The effect on these cytokines was inhibited by N-acetyl cysteine (NAC, 5 mM) or the NF-kB inhibitor, IKK-2 (10 uM). CSE treatment also increased cellular and mitochondrial ROS levels. The cellular ROS levels were normalized to control values by NAC treatment, although significant effects on mitochondrial ROS levels were observed only at short times (5') and effects on CFTR levels were not observed. In addition, CSE reduced the mitochondrial NADH-cytochrome c oxidoreductase (mCx I-III) activity, an effect that was not reverted by NAC. The reduced CFTR expression and the mitochondrial damage induced by CSE could not be normalized by NAC treatment, evidencing the need for a more specific reagent. In conclusion, CSE causes a sterile proinflammatory state and mitochondrial damage in Calu-3 cells that was partially recovered by NAC treatment. PMID- 29573704 TI - The uremic toxin hippurate promotes endothelial dysfunction via the activation of Drp1-mediated mitochondrial fission. AB - The accumulation of uremic toxins in chronic kidney disease (CKD) induces inflammation, oxidative stress and endothelial dysfunction, which is a key step in atherosclerosis. Accumulating evidence indicates increased mitochondrial fission is a contributing mechanism for impaired endothelial function. Hippurate, a uremic toxin, has been reported to be involved in cardiovascular diseases. Here, we assessed the endothelial toxicity of hippurate and the contribution of altered mitochondrial dynamics to hippurate-induced endothelial dysfunction. Treatment of human aortic endothelial cells with hippurate reduced the expression of endothelial nitric oxide synthase (eNOS) and increased the expression of intercellular cell adhesion molecule-1 (ICAM-1) and von Willebrand factor (vWF). The mechanisms of hippurate-induced endothelial dysfunction in vitro depended on the activation of Dynamin-related protein 1 (Drp1)-mediated mitochondrial fission and overproduction of mitochondrial reactive oxygen species (mitoROS). In a rat model in which CKD was induced by 5/6 nephrectomy (CKD rat), we observed increased oxidative stress, impaired endothelium-dependent vasodilation, and elevated soluble biomarkers of endothelial dysfunction (ICAM-1 and vWF). Similarly, endothelial dysfunction was identified in healthy rats treated with disease-relevant concentrations of hippurate. In aortas of CKD rats and hippurate treated rats, we observed an increase in Drp1 protein levels and mitochondrial fission. Inhibition of Drp1 improved endothelial function in both rat models. These results indicate that hippurate, by itself, can cause endothelial dysfunction. Increased mitochondrial fission plays an active role in hippurate induced endothelial dysfunction via an increase in mitoROS. PMID- 29573706 TI - Versatile ruthenium(II) dye towards blue-light emitter and dye-sensitizer for solar cells. AB - A versatile Ru(II) complex bearing an anthracene moiety was synthesized in our search for suitable compounds towards efficient molecular devices. The new engineered dye, cis-[Ru(dcbH2)(NCS)2(mbpy-anth)] (dcbH2=2,2'-bipyridyl-4,4' dicarboxylic acid, mbpy-anth=4-[N-(2-anthryl)carbamoyl]-4'-methyl-2,2' bipyridine), exhibits a blueish emission in a vibronically structured spectrum ascribed to the fluorescence of a 1LCAnth (ligand centered) excited state in the anthracene and has a potential to be exploited in the fields of smart lighting and displays. This complex was also employed in dye-sensitized solar cells with fairly efficient solar energy conversion with the use of self-assembled TiO2 compact layers beneath the TiO2 mesoporous film to prevent meso-TiO2/dye back reactions. Further photoelectrochemical investigations through incident photon-to current efficiency and electrochemical impedance spectra showed that the all-nano TiO2 compact layer acts as contact layers that increase the electron harvesting in the external circuit, enhancing efficiencies up to 50%. PMID- 29573705 TI - Peroxidasin-mediated crosslinking of collagen IV is independent of NADPH oxidases. AB - Collagen IV is a major component of the basement membrane in epithelial tissues. The NC1 domains of collagen IV protomers are covalently linked together through sulfilimine bonds, the formation of which is catalyzed by peroxidasin. Although hydrogen peroxide is essential for this reaction, the exact source of the oxidant remains elusive. Members of the NOX/DUOX NADPH oxidase family are specifically devoted to the production of superoxide and hydrogen peroxide. Our aim in this study was to find out if NADPH oxidases contribute in vivo to the formation of collagen IV sulfilimine crosslinks. We used multiple genetically modified in vivo model systems to provide a detailed assessment of this question. Our data indicate that in various peroxidasin-expressing tissues sulfilimine crosslinks between the NC1 domains of collagen IV can be readily detected in the absence of functioning NADPH oxidases. We also analyzed how subatmospheric oxygen levels influence the collagen IV network in collagen-producing cultured cells with rapid matrix turnover. We showed that collagen IV crosslinks remain intact even under strongly hypoxic conditions. Our hypothesis is that during collagen IV network formation PXDN cooperates with a NOX/DUOX-independent H2O2 source that is functional also at very low ambient oxygen levels. PMID- 29573707 TI - A novel tetrahydroisoquinoline (THIQ) analogue induces mitochondria-dependent apoptosis. AB - Lung cancer continues to be a leading cause of cancer-related death worldwide, with non-small cell lung cancer (NSCLC) accounting for more than 80% of lung cancer cases. Current therapies for NSCLC have only limited effect and treatment resistance develops rapidly. In a previous study, we have shown that C1 phenylethynyl tetrahydroisoquinoline (THIQ) analogue 4 has anti-proliferative activity against PC3 human prostate cancer cells. However, this anticancer effect was achieved with relatively high IC50 in A549 lung cancer cells. To improve the potency of the drug, in the present study, a series of novel THIQ analogues (analogues 5a-d) were prepared by using an oxidative C-H functionalization strategy, and their potential anticancer activities on A549 lung cancer cells were investigated. Among these analogues, analogue 5c can markedly inhibit A549 cell proliferation in a dose-dependent manner with a reasonable IC50 of 14.61 +/- 1.03 MUM. This effect was mediated by analogue 5c-induced G0/G1 phase arrest and cell apoptosis. Treatment with analogue 5c was shown to induce reactive oxygen species (ROS) accumulation, disruption of mitochondrial membrane potential, reduction of glutathione, elevation of intracellular calcium ion (Ca2+), and activation of Caspase-3. Furthermore, analogue 5c can lead to DNA double-strand break and the activation of p53 pathway in A549 cells. In conclusion, the oxidative C-H functionalization strategy to generate analogue 5c could improve the drug anticancer efficacy by inducing mitochondria-dependent apoptosis in A549 cells. PMID- 29573708 TI - Determinants of hospitalization and length of stay among people with dementia - An analysis of statutory health insurance claims data. AB - OBJECTIVE: Dementia is a crucial challenge in acute care hospitals. Using a retrospective claims data cohort, this paper explores dementia patients' acute hospitalization rates, risk factors, and length of stay. METHODS: The study used claims data from AOK PLUS, the largest statutory health insurance service (SHI) in Saxony, a federal state of Germany. The analysis included 61,239 people with dementia and 183,477 control subjects, all 65 years and older. Control subjects were age, gender, and regionally matched in a 1:3 ratio. Negative binomial hurdle regression was used to compare differences in hospitalization for the year 2014. RESULTS: People with dementia had 1.49 times higher adjusted odds of being hospitalized at least once (95% confidence interval [CI], 1.46-1.52). Among those individuals hospitalized at least once, dementia increased the number of readmissions by 18% (95% CI, 1.15-1.20). Dementia patients also had a 1.74 times higher odds for at least one emergency admission compared to individuals without dementia (95% CI, 1.70-1.78). Dementia patients' admission risk factors included having care dependency, being recently diagnosed with dementia and living outside a metropolitan region. The increased length of stay for people with dementia per year was mainly attributable to higher admission rates. CONCLUSIONS: Dementia patients are at higher risk for hospitalization, especially if they live outside the metropolitan region. Healthcare systems need to respond to the challenges resulting from the predicted demographic developments and increasing burden of dementia in the general population. PMID- 29573709 TI - Aquatic plants: Test species sensitivity and minimum data requirement evaluations for chemical risk assessments and aquatic life criteria development for the USA. AB - Phytotoxicity results from the publicly-available ECOTOX database were summarized for 20 chemicals and 188 aquatic plants to determine species sensitivities and the ability of a species-limited toxicity data set to serve as a surrogate for a larger data set. The lowest effect concentrations reducing the sublethal response parameter of interest by 50% relative to the controls (EC50) usually varied several orders of magnitude for the 119 freshwater and 69 saltwater plants exposed to the same test chemicals. Generally, algae were more sensitive than floating and benthic species but inter-specific differences for EC50 values were sometimes considerable within and between phyla and no consistently sensitive species was identified for the morphologically-diverse taxa. Consistent equivalencies of the phytotoxicity databases for freshwater-saltwater plants and floating-benthic macrophyte species were not demonstrated. Two species sensitivity distribution plots (SSDs) were constructed for each of the 20 chemicals, one based on all available phytotoxicity information (range = 10-76 test species) and another based on information for only five species recommended for pesticide hazard evaluations. HC5 values (hazardous concentration to 5% of test species) estimated from the two SSDs usually differed four-fold or less for the same chemical. HC5 values for the five species were often conservative estimates of HC5 values for the more species-populated data sets. Consequently, the collective response of the five test species shows promise as an interim aquatic plant minimum data requirement for aquatic life criteria development. In contrast, the lowest EC50 values for the five species usually were greater than HC5 values for the same test chemicals, a finding important to criteria supporting Final Plant Values. The conclusions may differ for comparisons based on other test chemicals, test species, response parameters and calculations. PMID- 29573710 TI - Expression of the human gene CYP1A2 enhances tolerance and detoxification of the phenylurea herbicide linuron in Arabidopsis thaliana plants and Escherichia coli. AB - The phenylurea herbicide, linuron (LIN), is used to control various types of weeds. Despite its efficient role in controlling weeds, it presents a persistent problem to the environment. In the current study, phytoremediation properties of transgenic CYP1A2 Arabidopsis thaliana plants to LIN were assessed. CYP1A2 gene was firstly cloned and expressed in bacteria before proceeding to plants. In presence of LIN, The growth of CYP1A2 expressing bacteria was superior compared to control bacteria transformed with the empty bacterial expression vector pET22b(+). No clear morphological changes were detected on CYP1A2 transgenic plants. However, significant resistance to LIN herbicide application either via spraying the foliar parts of the plant or via supplementation of the herbicide in the growth medium was observed for CYP1A2 transformants. Plant growth assays under LIN stress provide strong evidence for the enhanced capacity of transgenic lines to grow and to tolerate high concentrations of LIN compared to control plants. HPLC analyses showed that detoxification of LIN by bacterial extracts and/or transgenic plant leaves is improved as compared to the corresponding controls. Our data indicate that over expression of the human CYP1A2 gene increases the phytoremediation capacity and tolerance of Arabidopsis thaliana plants to the phenylurea herbicide linuron. PMID- 29573711 TI - Estimating the contribution of bacteriophage to the dissemination of antibiotic resistance genes in pig feces. AB - The transfer of antibiotic resistance genes (ARGs) in the environment is a threat to both human and animal health. However, the contribution of bacteriophages to the dissemination of resistance genes via transduction is rarely explored. In this study, we screened pig feces from three commercial farms in China for 32 clinically relevant ARG types to assess the presence of the ARG population in bacteria and bacteriophage and further to estimate the contribution of bacteriophages to the dissemination of antibiotic resistance. We found that bacteriophage DNA contained 35.5% of the target ARG types and sul1, blaTEM and ermB were found in 100% of the phage DNA samples. The most abundant genes in the bacterial population were ermB and fexA whereas ermB was the most abundant in bacteriophage. In contrast, floR was the least abundant ARG in both populations. Also, the ratio index of the abundance of ARGs in bacteriophage and bacteria was firstly used in this study as an estimator of bacteriophage ability to transmit ARGs. The ratio for qnrA was the greatest (about 10-1) and differed from the most abundant bacteriophage ARG ermB. In addition, fexA had the lowest ratio value (about 10-6) and not floR. These results illustrate that ARGs abundance and detection rates used alone probably be not suitable for comprehensively judging the contribution of bacteriophage to the dissemination of antibiotic resistance. A more suitable model is the application of three indices; occurrence rate, absolute abundance in bacteriophage and the ratio value as warning and monitoring tools for environmental ARG assessments in bacteriophages.

AB - Bisphenols and triclosan (TCS) are widely used in consumer products. However, knowledge on human exposure to these anthropogenic chemicals has remained limited in China, especially for children. In this study, concentrations of seven bisphenols and TCS were determined in 283 urine samples collected from South China children aged between 3 and 11 years old. Bisphenol A (BPA), bisphenol S (BPS) and TCS were frequently detected in urine samples, with a detection rate of 93%, 89%, and 95%, respectively. Urinary concentrations of Sigma7BPs (the sum concentrations of the seven bisphenols) ranged from 0.43 to 31.5 MUg/L, with a median value of 0.91 MUg/L, while TCS concentrations ranged from < limit of quantification to 21.9 MUg/L (median: 0.21 MUg/L). BPA was the predominant analogue (median: 0.35 MUg/L), accounting for 49.8% of Sigma7BPs. The urinary BPA concentrations in children from Guangzhou were significantly greater than those from Shenzhen. Correlation analysis suggested that multiple exposure sources to South China children likely existed for BPA, BPS, and TCS. Age, but not gender, was negatively associated with urinary residues of BPA and BPS (p < 0.05) and positively with TCS concentrations (p < 0.05). The estimated daily intake of Sigma7BPs (23.9 ng/kg bw/day) or TCS (5.63 ng/kg bw/day) was below the tolerant reference dose of BPA, indicating no considerable health hazard to South China children.

AB - Productive coastal and estuarine habitats can be degraded by contaminants including persistent organic pollutants (POPs) such as PCBs, dioxins, and organochlorine insecticides to the extent of official designation as contaminated sites. Top-predatory wildlife may continue to use such sites as the habitat often appears suitable, and thus bioaccumulate POPs and other contaminants with potential consequences on their health and fitness. Victoria and Esquimalt harbours are located on southern Vancouver Island, British Columbia (BC) and are federally designated contaminated sites due mainly to past heavy industrial activities, such as from shipyards and sawmills. We collected scat samples from river otters (Lontra canadensis) throughout an annual cycle, and combined chemical analysis with DNA genotyping to examine whether the harbour areas constituted a contaminant-induced ecological trap for otters. We confirmed spatial habitat use by radio telemetry of a subsample of otters. Fifteen percent of otter scat contained PCB concentrations exceeding levels considered to have adverse effects on the reproduction of mink (Neovison vison), and there were significant positive correlations between concentrations of PCBs and of thyroid (T3) and sex (progesterone) hormones in fecal samples. Radio telemetry data revealed that otters did not show directional movement away from the harbours, indicating their inability to recognize the contaminated site as a degraded habitat. However, analysis and modeling of the DNA genotyping data provided no evidence that the harbour otters formed a sink population and therefore were in an ecological trap. Despite the highly POP-contaminated habitat, river otters did not appear to be adversely impacted at the population level. Our study demonstrates the value of combining chemical and biological technologies with ecological theory to investigate practical conservation problems. PMID- 29573715 TI - Concentrations and congener profiles of chlorinated paraffins in domestic polymeric products in China. AB - Chlorinated paraffins (CPs) are widely used in domestic polymeric products as plasticizers and fire retardants. In this study, concentrations and congener profiles of short-chain and medium-chain chlorinated paraffins (SCCPs and MCCPs) were investigated in domestic polymeric products, including plastics, rubber and food packaging in China. The average concentrations of SCCPs in polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE) and food packaging were 234, 3968, 150 and 188 ng/g, respectively and the corresponding average concentrations of MCCPs in these samples were 37.4, 2537, 208 and 644 ng/g, respectively. The concentrations of CPs in rubber and polyvinylchloride (PVC) were significantly higher than in other matrices. The highest concentrations of SCCPs and MCCPs were found in a PVC cable sheath with 191 mg/g and 145 mg/g, respectively. Congener group profiles analysis indicated C11- and C13-congener groups were predominant in carbon homologues of SCCPs, and C14-congener groups were predominant in MCCPs. High levels of SCCPs and MCCPs in domestic polymeric products implied that they might be a significant source to the environment and human exposure.

AB - Complexity of anthropogenic influences on coastal ecosystems necessitates use of an integrated assessment strategy for effective interpretation and subsequent management. In this study a multiple lines of evidence (LOE) approach for sediment assessment, that combined use of chemistry, toxicity, and benthic community structure in the sediment quality triad was used to assess spatiotemporal changes and potential risks of persistent toxic substances (PTSs) in sediments of Masan Bay highlighting "long-term changes" between 1998 and 2014. Specific target objectives encompassed sedimentary PTSs (PAHs, alkylphenols (APs), and styrene oligomers), potential aryl hydrocarbon receptor (AhR; H4IIE luc assay)- and estrogen receptor (ER; MVLN assay)-mediated activities, and finally several ecological quality (EcoQ) indices of benthic community structure. Concentrations of target PTSs in Masan Bay sediments were generally less by half in 2014 compared to those measured in 1998. Second, AhR-mediated potencies in sediments also decreased during this time interval, whereas ER-mediated potencies increased (+3790%), indicating that there has been substantial ongoing, input of ER agonists over the past 16 years. Potency balance analysis revealed that only 3% and 22% of the AhR- and ER-mediated potencies could be explained by identified known chemicals, such as PAHs and APs, respectively. This result indicated that non-targeted AhR and ER agonists had a considerable presence in the sediments over time. Third, EcoQ indices tended to reflect PTSs contamination in the region. Finally, ratio-to-mean values obtained from the aforementioned three LOEs indicated that quality of sediments from the outer region of the bay had recovery more during the period of 16-years than did the inner region. Overall, the results showed that even with the progress supported by recent efforts from the Korean governmental pollution control, PTSs remain a threat to local ecosystem, especially in the inner region of Masan Bay. PMID- 29573716 TI - Wi-Fi is an important threat to human health. AB - Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. Each of these effects are also caused by exposures to other microwave frequency EMFs, with each such effect being documented in from 10 to 16 reviews. Therefore, each of these seven EMF effects are established effects of Wi-Fi and of other microwave frequency EMFs. Each of these seven is also produced by downstream effects of the main action of such EMFs, voltage-gated calcium channel (VGCC) activation. While VGCC activation via EMF interaction with the VGCC voltage sensor seems to be the predominant mechanism of action of EMFs, other mechanisms appear to have minor roles. Minor roles include activation of other voltage-gated ion channels, calcium cyclotron resonance and the geomagnetic magnetoreception mechanism. Five properties of non thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults. These general findings and data presented earlier on Wi-Fi effects were used to assess the Foster and Moulder (F&M) review of Wi-Fi. The F&M study claimed that there were seven important studies of Wi-Fi that each showed no effect. However, none of these were Wi-Fi studies, with each differing from genuine Wi-Fi in three distinct ways. F&M could, at most conclude that there was no statistically significant evidence of an effect. The tiny numbers studied in each of these seven F&M-linked studies show that each of them lack power to make any substantive conclusions. In conclusion, there are seven repeatedly found Wi-Fi effects which have also been shown to be caused by other similar EMF exposures. Each of the seven should be considered, therefore, as established effects of Wi-Fi. PMID- 29573717 TI - Soil contamination and sources of phthalates and its health risk in China: A review. AB - Phthalates (PAEs) are extensively used as plasticizers and constitute one of the most frequently detected organic contaminants in the environment. With the deterioration of eco-environment in China during the past three decades, many studies on PAE occurrence in soils and their risk assessments have been conducted which allow us to carry out a fairly comprehensive assessment of soil PAE contamination on a nation-wide scale. This review combines the updated information available associated with PAE current levels, distribution patterns (including urban soil, rural or agricultural soil, seasonal and vertical variations), potential sources, and human health exposure. The levels of PAEs in soils of China are generally at the high end of the global range, and higher than the grade II limits of the Environmental Quality Standard for soil in China. The most abundant compounds, di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP), display obvious spatial distribution in different provinces. It is noted that urbanization and industrialization, application of plastic film (especially plastic film mulching in agricultural soil) and fertilizer are the major sources of PAEs in soil. Uptake of PAEs by crops, and human exposure to PAEs via ingestion of soil and vegetables are reviewed, with scientific gaps highlighted. PMID- 29573718 TI - The influence of microplastics and halogenated contaminants in feed on toxicokinetics and gene expression in European seabass (Dicentrarchus labrax). AB - When microplastics pollute fish habitats, it may be ingested by fish, thereby contaminating fish with sorbed contaminants. The present study investigates how combinations of halogenated contaminants and microplastics associated with feed are able to alter toxicokinetics in European seabass and affect the fish. Microplastic particles (2%) were added to the feed either with sorbed contaminants or as a mixture of clean microplastics and chemical contaminants, and compared to feed containing contaminants without microplastics. For the contaminated microplastic diet, the accumulation of polychlorinated biphenyls (PCBs) and brominated flame retardants (BFRs) in fish was significantly higher, increasing up to 40 days of accumulation and then reversing to values comparable to the other diets at the end of accumulation. The significant gene expression results of liver (cyp1a, il1beta, gstalpha) after 40 days of exposure indicate that microplastics might indeed exacerbate the toxic effects (liver metabolism, immune system, oxidative stress) of some chemical contaminants sorbed to microplastics. Seabass quickly metabolised BDE99 to BDE47 by debromination, probably mediated by deiodinase enzymes, and unlike other contaminants, this metabolism was unaffected by the presence of microplastics. For the other PCBs and BFRs, the elimination coefficients were significantly lower in fish fed the diet with contaminants sorbed to microplastic compared to the other diets. The results indicate that microplastics affects liver detoxification and lipid distribution, both of which affect the concentration of contaminants. PMID- 29573719 TI - Anti-inflammatory activity of mulberrofuran K isolated from the bark of Morus bombycis. AB - Morus bombycis Koidzumi, commonly known as silkworm mulberry, is a plant belonging to family Moraceae. It has been used in Asian countries as a traditional medicine for treating hypertension, diabetes, and inflammatory disorders. In this study, we isolated eleven compounds from the cortex of M. bombycis and evaluated their inhibitory effects on nitric oxide (NO) production as an indicator of their anti-inflammatory activities using lipopolysaccharide (LPS)-stimulated murine macrophages. Compound 4 showed the most potent inhibitory activity on NO production. It was identified as mulberrofuran K (MFK). Anti inflammatory activity of MFK was then carried out using LPS-stimulated RAW264.7 cells. MFK suppressed the production of NO, reactive oxygen species (ROS), and proinflammatory cytokines (interleukin (IL)-1beta, IL-6 and tumor necrosis factor alpha (TNF-alpha)) in a concentration-dependent manner. Western blot analysis revealed that MFK treatment inhibited expression levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). MFK also inhibited transcriptional activation of nuclear factor-kappaB (NF-kappaB) and extracellular-regulated kinases (ERK) 1/2 in LPS-stimulated murine macrophages. These results suggest that MFK, an anti-inflammatory constituents of M. bombycis cortex, has potential as a therapeutic candidates for preventing and treating inflammatory diseases. PMID- 29573720 TI - Postpartum blood transfusion and hemorrhage as independent risk factors for venous thromboembolism. AB - INTRODUCTION: Profuse postpartum hemorrhage (PPH) and red blood cell (RBC) transfusion have been suggested to be associated with venous thromboembolic events (VTE). However, it is not fully clear if they are independent major risk factors. METHODS: Women who gave birth in the Stockholm area between 1999 and 2002 were those studied, i.e., before the implementation of guidelines for thromboprophylaxis in pregnancy. In this population-based cohort study the Swedish Medical Birth Registry was linked to the National Discharge Registry and to the transfusion database. Cases with VTE were identified as well as the patient's transfusion history. The main outcome was an assessment of RBC transfusion and PPH as independent risk factors for postpartum thrombosis, analyzed in logistic regression models. RESULTS: Out of the 82,376 deliveries, 56 cases of postpartum VTE were identified (0.70/00). Compared to the control group, the risk of VTE increased with the number of RBC transfusions: 1 to 3 units (OR = 3.3, 95% CI 1.2-8.9) and >3 units (OR = 5.2, 95%CI 1.7-16.1), but PPH was not found to be a major risk factor (OR = 1.4, 95% CI 0.5-3.5). Surprisingly, the small group treated with plasma in addition to RBC transfusion were not at a significantly increased risk (OR = 1.8, 95% CI 0.2-14.0). Preeclampsia and placental abruption were major risk factors. CONCLUSION: We found RBC transfusion, but not PPH alone, to be an independent risk factor for postpartum VTE and propose that it should be included in the thromboprophylaxis algorithm for implementation during pregnancy. PMID- 29573721 TI - Novel heparin mimetics reveal cooperativity between exosite 2 and sodium-binding site of thrombin. AB - INTRODUCTION: Thrombin is a primary target of most anticoagulants. Yet, thrombin's dual and opposing role in pro- as well as anti- coagulant processes imposes considerable challenges in discovering finely tuned regulators that maintain homeostasis, rather than disproportionately changing the equilibrium to one side. In this connection, we have been studying exosite 2-mediated allosteric modulation of thrombin activity using synthetic agents called low molecular weight lignins (LMWLs). Although the aromatic scaffold of LMWLs is completely different from the polysaccharidic scaffold of heparin, the presence of multiple negatively charged groups on both ligands induces binding to exosite 2 of thrombin. This work characterizes the nature of interactions between LMWLs and thrombin to understand the energetic cooperativity between exosite 2 and active site of thrombin. MATERIALS AND METHODS: The thermodynamics of thrombin-LMWL complexes was studied using spectrofluorimetric titrations as a function of ionic strength and temperature of the buffer. The contributions of enthalpy and entropy to binding were evaluated using classic thermodynamic equations. Label-free surface plasmon resonance was used to assess the role of sodium ion in LMWL binding to thrombin at a fixed ionic strength. RESULTS AND CONCLUSIONS: Exosite 2 induced conformational change in thrombin's active site is strongly dependent on the structure of the ligand, which has consequences with respect to regulation of thrombin. The ionic and non-ionic contributions to binding affinity and the thermodynamic signature were highly ligand specific. Interestingly, LMWLs display preference for the sodium-bound form of thrombin, which supports the existence of an energetic coupling between exosite 2 and sodium-binding site of thrombin. PMID- 29573722 TI - Systematic review and meta-analysis of the association of combined oral contraceptives on the risk of venous thromboembolism: The role of the progestogen type and estrogen dose. AB - INTRODUCTION: Currently available combined oral contraceptives (COC) reportedly increase the risk of venous thromboembolism (VTE). We aimed to quantify this risk considering both progestogen type and estrogen dose. MATERIALS AND METHODS: PubMed, Embase and LIVIVO were searched for relevant publications until April 2017. Case-control and cohort studies including healthy women taking COC and assessing incident VTE as outcome were selected. Adjusted relative risks (RR) with 95% confidence intervals (CI) derived from random effects model using a generic inverse-variance approach are reported. RESULTS: Overall, 1,359 references were identified and 17 studies were included in the meta-analysis. The pooled RR of VTE was associated with various COC, with the association depending on their respective estrogen dose and progestogen type. Compared to the reference, levonorgestrel with 30-40 MUg ethinylestradiol, the overall risk of VTE was higher for all other COC. Preparations with desogestrel with 30-40 MUg estrogen showed the highest relative risk (RR: 1.46; 95% CI: 1.33-1.59), while RRs for drospirenone (30-40 MUg ethinylestradiol) and desogestrel (30-40/20 MUg ethinylestradiol) were lower. COC containing gestodene and cyproterone with 30-40 MUg estrogen showed the lowest risk (RR: 1.27; 95% CI: 1.15-1.41 and RR: 1.29; 95% CI: 1.12-1.49, respectively). CONCLUSIONS: Compared to levonorgestrel with 30 40 MUg ethinylestradiol, all COC showed a significantly increased VTE risk. The association varied depending on the progestogen type and the dose of estrogen. Our results suggest that the prescription of COC with the lowest possible dose of ethinylestradiol may help to avoid VTE cases among young, healthy women.

AB - Benzo[a]pyrene (BaP) is one of the most important polycyclic aromatic hydrocarbons (PAHs), which are widely present in the marine environment. Because of its teratogenic, mutagenic, and carcinogenic effects on various organisms, the toxicity of BaP is of great concern. In this study, we focused on the toxic effects of BaP (1 ug/L and 10 ug/L) on gills of the pearl oyster Pinctada martensii using combined metabolomic and proteomic approaches. At the metabolome level, the high concentration of BaP mainly caused abnormal energy metabolism, osmotic regulation and immune response marked by significantly altered metabolites in gills. At the proteome level, both concentrations of BaP mainly induced signal transduction, transcription regulation, cell growth, stress response, and energy metabolism. Overall, the research demonstrated that the combination of proteomic and metabolomic approaches could provide a significant way to elucidate toxic effects of BaP on P. martensii. PMID- 29573724 TI - Tetracycline resistance genes are more prevalent in wet soils than in dry soils. AB - This study aimed to reveal the effects of water content on the spread of tetracycline resistance genes (TRGs) in the soil. Amendments of four samples with different soil water contents, namely 16% (dry soil) and 25% (wet soil), and with or without pig manures (PM) were conducted under laboratory conditions. Quantitative polymerase chain reaction (q-PCR) results showed that the relative abundance of TRGs (tetB, tetC, tetM, tetO, tetT, and tetZ) in the wet soils was significantly higher than that in the dry soils whether under fertilization or non-fertilization conditions. Moreover, PM application enhanced the relative abundance of TRGs. The absolute copies of TRGs did not decline with the decrease in 16S rRNA genes in wet soils, implying that most TRGs were probably located in facultative anaerobic bacteria. However, cultivable tetracycline-resistant bacteria (TRB) in the wet soils were not in line with the q-PCR results, further indicating that aerobes might not account for the increases in the relative abundance of TRGs. Diversities of aerobic TRB were significantly higher in the wet soils than in the dry soils, especially on days 14 and 28. The patterns of community structures of aerobic TRB in the wet soils or dry soils containing PM were different from those in the dry soils. Together, this study showed that the variations in bacterial communities between the wet and dry soils, especially reflected in the diversity of aerobic TRB and/or community structure of facultative anaerobic TRB, might be an important reason behind the changes in the abundance of TRGs. PMID- 29573725 TI - Pretilachlor toxicity is decided by discrete photo-acclimatizing conditions: Physiological and biochemical evidence from Anabaena sp. and Nostoc muscorum. AB - The current study was undertaken to elucidate the impact of the herbicide pretilachlor (3 ug ml-1 and 6 ug ml-1) on cyanobacteria, Nostoc muscorum ATCC 27893 and Anabaena sp. PCC 7120 under three levels of photoacclimatization (suboptimum, 25 umol photon m-2 s-1; optimum, 75 umol photon m-2 s-1; and supra optimum, 225 umol photon m-2 s-1) by analyzing certain physiological (biomass accumulation, photosynthesis, Chl a fluorescence and respiration) and biochemical parameters (photosynthetic pigments- chlorophyll a, carotenoids and phycocyanin; reactive oxygen species- O2*-, H2O2, lipid peroxidation; antioxidant system- superoxide dismutase, peroxidise, catalase and glutathione-S-transferase). The light conditioning played the most prominent role in deciding the extent of herbicide toxicity on both the tested cyanobacteria as the maximum toxicity was observed in suboptimum light acclimatized cyanobacterial cells corroborated by the least growth in the same cells. The impact of pretilachlor treatment on photosystem II photochemistry viz. phiP0, ?0, phiE0, PIABS, ABS/RC, TR0/RC, ET0/RC and DI0/RC was also altered by light acclimatization. The percent rise in oxidative stress markers (SOR and H2O2) and consequent lipid peroxidation (MDA equivalents) were also highest in suboptimum light acclimatized cells exposed to pretilachlor which could not be prospered with compatible antioxidant performance. Conversely, supra-optimum light acclimatized cells of both the cyanobacteria was found to accelerate the activities of all the studied enzymes and thus able to counterbalance the pretilachlor toxicity and supported the healthier growth. PMID- 29573726 TI - Can chronic exposure to imidacloprid, clothianidin, and thiamethoxam mixtures exert greater than additive toxicity in Chironomus dilutus? AB - Widespread agricultural use of neonicotinoid insecticides has resulted in frequent detection of mixtures of these compounds in global surface waters. Recent evidence suggests that neonicotinoid mixtures can elicit synergistic toxicity in aquatic insects under acute exposure conditions, however this has not been validated for longer exposures more commonly encountered in the environment. Therefore, we aimed to characterize the chronic (28-day) toxicity of imidacloprid, clothianidin, and thiamethoxam mixtures under different doses and mixture ratios to determine if the assumption of synergistic toxicity would hold under more environmentally realistic exposure settings. The sensitive aquatic insect Chironomus dilutus was used as a representative test species, and successful emergence was used as a chronic endpoint. Applying the MIXTOX modeling approach, predictive parametric models were fitted using single-compound toxicity data and statistically compared to observed toxicity in subsequent mixture tests. Imidacloprid-clothianidin, clothianidin-thiamethoxam and imidacloprid clothianidin-thiamethoxam mixtures did not significantly deviate from concentration-additive toxicity. However, the cumulative toxicity of the imidacloprid-thiamethoxam mixture deviated from the concentration-additive reference model, displaying dose-ratio dependent synergism and resulting in up to a 10% greater reduction in emergence from that predicted by concentration addition. Furthermore, exposure to select neonicotinoid mixtures above 1.0 toxic unit tended to shift sex-ratios toward more male-dominated populations. Results indicate that, similar to acute exposures, the general assumption of joint additivity cannot adequately describe chronic cumulative toxicity of all neonicotinoid mixtures. Indeed, our observations of weak synergism and sex-ratio shifts elicited by some mixture combinations should be considered in water quality guideline development and environmental risk assessment practices for neonicotinoid insecticides, and explored in further investigations of the effects of neonicotinoid mixtures on aquatic communities. PMID- 29573727 TI - A novel electrochemical sensor based on silver/halloysite nanotube/molybdenum disulfide nanocomposite for efficient nitrite sensing. AB - In the present study, the silver/halloysite nanotube/molybdenum disulfide (Ag/HNT/MoS2) nanocomposite was successfully synthesized. For this purpose, the lumen of HNTs was firstly modified by silver to generate Ag nanorods via chemical process and then the MoS2 layers deposited on the Ag/HNT nanocomposite by hydrothermal method. The characterization of Ag/HNT/MoS2 nanocomposite were investigated by field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectra (XPS), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) analyses. The nanocomposite modified carbon paste electrode (CPE) was applied for the electrocatalytic detection of nitrite in aqueous solutions. It was demonstrated that the treatment of HNTs with Ag and MoS2 materials enhanced the catalytic performance of modified CPE. At optimal experimental conditions, the designed sensor displayed remarkable sensing ability toward nitrite oxidation, offering a good linearity from 2 to 425 uM. The limit of detection (LOD) of the proposed strategy was estimated to be 0.7 uM based S/N = 3. The good reproducibility, acceptable stability, fast response time and anti interference performance of the proposed assay suggests that the modified CPE has great potential working as a nitrite electrochemical sensor for environmental applications. PMID- 29573729 TI - Contrastive study for coadsorption of copper and two dihydroxybenzene isomers by a multi-amine modified resin. AB - Coadsorption of Cu(II) and two dihydroxybenzene isomers (hydroquinone, HQ and catechol, CAT) onto a multi-amine modified resin (CEAD) were comparatively studied. The presence of Cu(II) promoted adsorption of both HQ and CAT by a maximum of 25.8% and 41.6%, respectively. However, two diphenols exerted a very different influence on Cu(II) uptake. Higher concentrations of HQ consistently suppressed Cu(II) adsorption while the coexistence of CAT facilitated it, especially at lower CAT concentrations. The interactions among solutes and adsorbents were revealed by means of kinetic tracking, sequential adsorption experiments, and characterizations/calculations (FTIR, XPS, MINTEQ and DFT). Cu(II) and HQ/CAT competed for amine sites with the order of adsorption affinity as HQ > Cu(II) > CAT. The bridging effect of Cu(II) forming ternary complexes (amine-Cu-CAT/HQ) on the resin phase was the dominant mechanism for the enhanced adsorption of diphenols. The [Cu-CAT] complex species showed a lower affinity to bind directly to amine sites compared with free Cu2+. Instead, the complex could be attracted by the polyphenyl matrix of CEAD, contributing to the increase of Cu(II) adsorption. Additionally, Cu(II) and diphenols were successively recovered, and CEAD could be stably reused. The findings will guide adsorbent applications and the environmental fate of concurrent heavy metals and phenolic compounds.

AB - The suppression effect of graphene in the fire hazards and smoke toxicity of polymer composites has been seriously limited by both mass production and weak interfacial interaction. Though the electrochemical preparation provides an available approach for mass production, exfoliated graphene could not strongly bond with polar polymer chains. Herein, mussel-inspired functionalization of electrochemically exfoliated graphene was successfully processed and added into polar thermoplastic polyurethane matrix (TPU). As confirmed by SEM patterns of fracture surface, functionalized graphene possessing abundant hydroxyl could constitute a forceful chains interaction with TPU. By the incorporation of 2.0 wt % f-GNS, peak heat release rate (pHRR), total heat release (THR), specific extinction area (SEA), as well as smoke produce rate (SPR) of TPU composites were approximately decreased by 59.4%, 27.1%, 31.9%, and 26.7%, respectively. A probable mechanism of fire retardant was hypothesized: well-dispersed f-GNS constituted tortuous path and hindered the exchange process of degradation product with barrier function. Large quantities of degradation product gathered round f-GNS and reacted with flame retardant to produce the cross-linked and high degree graphited residual char. The simple functionalization for electrochemically exfoliated graphene impels the application of graphene in the fields of flame retardant composites.

AB - The construction and biofunctionalization of the poly (E-caprolactone) (PCL) chitosan (CHIT) nanofibrous mats, which included Polyamidoamine (PAMAM) dendrimer modified montmorillonite (Mt), for the cell adhesion and electrochemical cytosensing were accomplished in this report. After the intercalation of the PAMAM generation zero dendrimer into the Mt, PAMAM-Mt decorated PCL-CHIT electrospun nanofibers were formed. The addition of PAMAM caused the decrease of contact angle of PCL-CHIT nanofibers. The covalent immobilization of a tripeptide namely Arginylglycylaspartate (RGD) on both the PCL-CHIT/Mt and PCL-CHIT/PAMAM-Mt surface was carried out. U87-MG and HaCaT (negative control) cell lines were incubated on the PCL-CHIT/Mt/RGD and PCL-CHIT/PAMAM-Mt/RGD. The proliferation studies and imaging of the cells were carried out on these fibers. Finally, electrochemical measurements were performed after each modification step by differential pulse/cyclic voltammetry and electrochemical impedance spectroscopy. U87-MG cells were grown better than HaCaT cells on the PCL-CHIT/PAMAM-Mt/RGD surfaces. To the best of our knowledge, there is no study that developed electrochemical cytosensor using electrospun nanofibers as a cell adhesion platform.

AB - The biotreatment of recalcitrant wastes in microbial fuel cells (MFCs) rather than chemical, physical, and advanced oxidation processes is a low-cost and eco friendly process. In this study, sulfate-reducing mixed communities in MFC anodic chamber were employed for simultaneous electricity generation, dye degradation, and sulfate reduction. A power generation of 258 +/- 10 mW/m2 was achieved under stable operating conditions in the presence of electroactive sulfate-reducing bacteria (SRB). The SRBs dominant anodic chambers result in dye, chemical oxygen demand (COD), and sulfate removal of greater than 85% at an initial COD (as lactate)/SO42- mass ratio of 2.0 and dye concentration of 100 mg/L. The effects of the COD/SO42- ratio (5.0:1.0-0.5:1.0) and initial diazo dye concentration (100 1000 mg/L) were studied to evaluate and optimize the MFC performance. Illumina Miseq technology for bacterial community analysis showed that Proteobacteria (89.4%), Deltaproteobacteria (52.7%), and Desulfovibrio (48.2%) were most dominant at phylum, class, and genus levels, respectively, at the MFC anode. Integration of anaerobic SRB culture in MFC bioanode for recalcitrant chemical removal and bioenergy generation may lead to feasible option than the currently used technologies in terms of overall pollutant treatment.

AB - OBJECTIVES: In the context of the first clinical trial of vagus nerve stimulation (VNS) in Crohn's disease (CD), our main objective was to quantify the acute and chronic effects of VNS on brain activity in CD patients. METHODS: We measured the electroencephalogram (EEG) in 9CD patients under VNS at 10 Hz just before VNS initiation, after 6 weeks and after 12 months of chronic VNS. RESULTS: Acute VNS induced increased spectral power in delta and theta bands on frontal, temporal and occipital electrodes. The main significant modulation was the 12 months' chronic effect of VNS which consisted mainly in a decreased power in the alpha frequency band which was correlated with the normalization of bowel mucosal inflammation, anxiety state and vagal tone. CONCLUSIONS: In addition to the activation of vagal efferent fibers that regulate the autonomic nervous system, our data suggest that chronic VNS has a regulatory action via afferent vagal fibers on anxio-depressive symptomatology associated to CD, which could be directly highlighted by the modulation of EEG alpha power known to be associated to depressed states. SIGNIFICANCE: This is the first report of the central effects of VNS in CD patients.

AB - In this study, a systematic data acquisition and mining strategy aimed at the traditional Chinese medicine (TCM) complex system based on ultra high-performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UHPLC-Q-TOF-MS) was reported. The workflow of this strategy is as follows: First, the high resolution mass data are acquired by both data-dependent acquisition mode (DDA) and data-independent acquisition mode (DIA). Then a global data mining that combined targeted and non-targeted compound finding is applied to analyze mass spectral data. Furthermore, some assistant tools, such as key product ions (KPIs), are employed for compound hunting and identification. The TCM Ziwan (ZW, Aster tataricus rhizoma) was used to illustrate this strategy for the first time. In this research, total 131 compounds including organic acids, peptides, terpenes, steroids, flavonoids, coumarins, anthraquinones and aldehydes were identified or tentatively characterized in ZW based on accurate mass measurements within +/-5 ppm error, and 50 of them were unambiguously confirmed by comparing standard compounds. Afterwards, based on the traditional Chinese medical theory and the key determinants of firing patterns of ventral tegmental area (VTA) dopamine (DA) neurons in the development of depression, the confirmed compounds were subsequently evaluated the pharmacological effect of activity of VTA DA neurons and anti-depressive efficacy. This research provided not only a chemical profiling for further in vivo study of ZW, but also an efficient data acquisition and mining strategy to profile the chemical constituents and find new bioactive substances for other TCM complex system.

AB - Arecoline is the primary active and toxic constituent of areca nut. Arecaidine and arecoline N-oxide are two major active metabolites of arecoline. In this work, an accurate and simple high performance liquid chromatography tandem mass spectrometry method for simultaneous quantification of arecoline, arecaidine and arecoline N-oxide in rat plasma was developed and fully validated to study their pharmacokinetic behaviors in rats. After extracted from rat plasma by protein precipitation with methanol and then concentrated, the analytes were chromatographic separated on a Sepax Sapphire C18 analytical column. The mobile phase consisted of methanol and 2 mM ammonium acetate buffer solution containing 0.2% (v/v) formic acid (8:92, v/v) under isocratic elution. The analytes were detected by multiple reaction monitoring (MRM) with an electrospray ionization source in the positive ion mode. The transitions of m/z 156.2 -> 53.2, m/z 142.2 > 44.2 and m/z 172.2 -> 60.2 were selected for arecoline, arecaidine and arecoline N-oxide, respectively. The method was linear over the concentration range of 0.5-100 ng/mL for arecoline, 5-5000 ng/mL for arecaidine and arecoline N oxide with no carry-over effect. The accuracies and intra- and inter-batch precisions were all within the acceptance limits. No matrix effect and potential interconversion between the analytes and other metabolites were observed in this method. The validated method was further employed to a preclinical pharmacokinetic study of arecoline, arecaidine and arecoline N-oxide after oral treatment with 20 mg/kg arecoline to rats. PMID- 29573736 TI - High throughput method to characterize acid-base properties of insoluble drug candidates in water. AB - In drug design experimental characterization of acidic groups in candidate molecules is one of the more important steps prior to the in-vivo studies. Potentiometry combined with Yasuda-Shedlovsky extrapolation is one of the more important strategy to study drug candidates with low solubility in water, although, it requires a large number of sequences to determine pKa values at different solvent-mixture compositions to, finally, obtain the pKa in water (pwwKa) by extrapolation. We have recently proposed a method which requires only two sequences of additions to study the effect of organic solvent content in liquid chromatography mobile phases on the acidity of the buffer compounds usually dissolved in it along wide ranges of compositions. In this work we propose to apply this method to study thermodynamic pwwKa of drug candidates with low solubilities in pure water. Using methanol/water solvent mixtures we study six pharmaceutical drugs at 25 degrees C. Four of them: ibuprofen, salicylic acid, atenolol and labetalol, were chosen as members of carboxylic, amine and phenol families, respectively. Since these compounds have known pwwKa values, they were used to validate the procedure, the accuracy of Yasuda-Shedlovsky and other empirical models to fit the behaviors, and to obtain pwwKa by extrapolation. Finally, the method is applied to determine unknown thermodynamic pwwKa values of two pharmaceutical drugs: atorvastatin calcium and the two dissociation constants of ethambutol. The procedure proved to be simple, very fast and accurate in all of the studied cases. PMID- 29573737 TI - Polymerization shrinkage stress of resin-based dental materials: A systematic review and meta-analyses of technique protocol and photo-activation strategies. AB - PURPOSE: A systematic review was conducted to determine whether there were any alternative technique or additional step strategies available to reduce and control polymerization shrinkage stress development in dental resin-based restorative materials. DATA SOURCES: This report followed the PRISMA Statement. A total of 36 studies were included in this review. Two reviewers performed a literature search up to December 2016, without restriction of the year of publication, in seven databases: PubMed, Web of Science, Scopus, SciELO, LILACS, IBECS, and BBO. STUDY SELECTION: Only in vitro studies that evaluated polymerization shrinkage stress by direct testing were included. Pilot studies, reviews and in vitro studies that evaluated polymerization shrinkage stress by indirect methods (e.g., microleakage or cuspal deflection measurements), finite elemental analysis or mathematical models were excluded. Of the 6.113 eligible articles, 36 studies were included in the qualitative analysis, and the meta analysis was performed with 25 studies. A global comparison was performed with random-effects models (alpha = 0.05). The strategies were subdivided as follows: the use of an alternative technique protocol of placing the material inside the tooth cavity; the modification of the irradiation intensity or total energy delivered to the material; the use of an alternative light-curing source; or the use of an alternative photo-activation mode. All alternative strategies showed statistically significant differences when compared with their respective controls (p < 0.05). CONCLUSION: The use of alternative light-curing sources contributed more to minimizing stress development than placing the material by means of an alternative technique protocol or by modifying the irradiant intensity or total energy delivered to the material during photo-activation. Moreover, the use of an alternative photo-activation mode (intermittent light, exponential, soft-start or pulse delay modes) was shown to be an effective strategy for reducing and controlling stress development in resin-based dental materials. PMID- 29573738 TI - Mind maps and network analysis to evaluate conceptualization of complex issues: A case example evaluating systems science workshops for childhood obesity prevention. AB - Across disciplines, it is common practice to bring together groups to solve complex problems. Facilitators are often asked to help groups organize information about and better understand the problem in order to develop and prioritize solutions. However, despite existence of several methods to elicit and characterize how individuals and groups think about and conceptualize an issue, many are difficult to implement in practice-based settings where resources such as technology and participant time are limited and research questions shift over time. This paper describes an easy-to-implement diagramming technique for eliciting conceptualization and a flexible network analysis method for characterizing changes in both individual and group conceptualization. We use a case example to illustrate how we used the methods to evaluate African American adolescent's conceptual understanding of obesity before and after participating in a series of four systems thinking workshops. The methods produced results that were sensitive to changes in conceptualization that were likely driven by the specific activities employed during the workshop sessions. The methods appear strong for capturing salient levels of conceptualization at both individual and collective levels. The paper concludes with a critical examination of strengths and weaknesses of the methods and implications for future practice and research. PMID- 29573739 TI - Comparisons of tumor-infiltrating lymphocyte levels and the 21-gene recurrence score in ER-positive/HER2-negative breast cancer. AB - BACKGROUND: Recent studies have shown that tumors with extensive tumor infiltrating lymphocytes (TILs) have a higher probability of pathologic complete response, even in luminal/human epidermal growth factor 2 (HER2)-negative breast cancer. We compared TIL levels and the 21-gene recurrence score (RS) in estrogen receptor (ER)-positive/HER2-negative breast cancer. METHODS: We evaluated the percentage of stromal TILs in 198 ER-positive/HER2-negative patients in whom RS was obtained by examining slides of surgical specimens by standardized methodology proposed by the international TIL Working Group. TIL levels were categorized as high (>= 60%), intermediate (11-59%), or low (<= 10%). All tumors were treatment-naive. RESULTS: Ninety-seven (49.0%), 88 (44.4%), and 13 patients (6.6%) had low, intermediate, and high TIL levels, respectively. There was a significant but weak correlation between continuous RS and continuous TIL levels (Pearson's R = 0.201, p = 0.004). The mean RS was significantly highest in high TIL tumors (17.8 +/- 10.7 in low TIL tumors, 19.4 +/- 8.7 in intermediate TIL tumors, and 26.2 +/- 8.2 in high TIL tumors; p = 0.014). However, when we compared categorized RS and TIL levels, we found that tumors with high TIL levels tended to have higher RS (>= 26) but it was not significant (p = 0.155). Furthermore, multivariate analysis revealed that high RS was not an independent factor associated with high TIL levels. Chemo-endocrine therapy was more frequently performed among patients with high TILs and less frequently among those with low or intermediate TILs (p < 0.001). CONCLUSIONS: Despite of a weak correlation between continuous TIL levels and RS, we found that tumors with high TIL levels tended to have a higher RS in ER-positive/HER2-negative breast cancer. Further study is warranted considering the clinical outcomes. PMID- 29573740 TI - Posturography and dynamic pedobarography in lame dogs with elbow dysplasia and cranial cruciate ligament rupture. AB - BACKGROUND: The usefulness of studying posture and its modifications due to locomotor deficiencies of multiple origins has been widely proven in humans. To assess its suitability in the canine species, static posturography and dynamic pedobarography were performed on lame dogs affected with unilateral elbow dysplasia and cranial cruciate ligament rupture by using a pressure platform. With this objective, statokinesiograms and stabilograms, the percentage of pressure distribution between limbs, paw area, mean pressure, and peak pressure, were obtained from lame and sound dogs. These data were compared with Peak Vertical Force values originated from a force platform in the same recording sessions. RESULTS: Significant differences were found in the parameters mentioned above between sound and lame dogs and limbs. CONCLUSIONS: Posturography and pedobarography are useful and reliable for the monitoring of fore and hindlimb lameness in dogs, providing a new set of parameters for lameness detection. PMID- 29573741 TI - HIV-1 Tat-induced diarrhea is improved by the PPARalpha agonist, palmitoylethanolamide, by suppressing the activation of enteric glia. AB - BACKGROUND: Diarrhea is a severe complication in HIV-1-infected patients with Trans-activator of transcription (HIV-1 Tat) protein being recognized as a major underlying cause. Beside its direct enterotoxic effects, Tat protein has been recently shown to affect enteric glial cell (EGC) activity. EGCs regulate intestinal inflammatory responses by secreting pro-inflammatory molecules; nonetheless, they might also release immune-regulatory factors, as palmytoilethanolamide (PEA), which exerts anti-inflammatory effects by activating PPARalpha receptors. We aimed at clarifying whether EGCs are involved in HIV-1 Tat-induced diarrhea and if PEA exerts antidiarrheal activity. METHODS: Diarrhea was induced by intracolonic administration of HIV-1 Tat protein in rats at day 1. PEA alone or in the presence of peroxisome proliferator-activated receptor (PPAR) antagonists was given intraperitoneally from day 2 to day 7. S100B, iNOS, NF kappaB, TLR4 and GFAP expression were evaluated in submucosal plexi, while S100B and NO levels were measured in EGC submucosal plexi lysates, respectively. To verify whether PEA effects were PPARalpha-mediated, PPARalpha-/- mice were also used. After 7 days from diarrhea induction, endogenous PEA levels were measured in submucosal plexi homogenates deriving from rats and PPARalpha-/- mice. RESULTS: HIV-1 Tat protein induced rapid onset diarrhea alongside with a significant activation of EGCs. Tat administration significantly increased all hallmarks of neuroinflammation by triggering TLR4 and NF-kappaB activation and S100B and iNOS expression. Endogenous PEA levels were increased following HIV-1 Tat exposure in both wildtype and knockout animals. In PPARalpha-/- mice, PEA displayed no effects. In wildtype rats, PEA, via PPARalpha-dependent mechanism, resulted in a significant antidiarrheal activity in parallel with marked reduction of EGC-sustained neuroinflammation. CONCLUSIONS: EGCs mediate HIV-1 Tat induced diarrhea by sustaining the intestinal neuroinflammatory response. These effects are regulated by PEA through a selective PPARalpha-dependent mechanism. PEA might be considered as an adjuvant therapy in HIV-1-induced diarrhea. PMID- 29573742 TI - Systemic inflammation in dogs with advanced-stage heart failure. AB - BACKGROUND: Although human studies have shown that inflammation plays a role in the development of congestive heart failure, scarce information exists on white blood cell count (WBC) and differential cell counts in various stages of heart failure in man and dogs. A few studies demonstrated increased concentrations of C reactive protein (CRP), a major acute-phase protein, in cardiac diseases in dogs. Our research aimed to investigate whether CRP concentration, WBC and neutrophil count (NEUT), as markers of systemic inflammation, are elevated in canine cardiovascular patients. We also aimed to find out whether there is an association between CRP concentration and WBC and NEUT, as well as associations between these inflammatory markers and selected echocardiographic parameters. Sixty-two client-owned canine cardiac patients and 12 healthy dogs were included in the study. The patients were classified into International Small Animal Cardiac Health Council classes (ISACHC I-III). The serum CRP concentration was determined using a canine CRP test kit. WBC and NEUT were determined using an automated hematology analyzer. RESULTS: Significantly higher serum CRP concentration, WBC and NEUT were found in the decompensated stage of heart failure (ISACHC III) compared with healthy dogs and with patients in ISACHC group II and ISACHC group I. Serum CRP concentration significantly positively correlated with WBC (r = 0.65, P < 0.001) and NEUT (r = 0.58, P = 0.002) in the ISACHC III group, while no significant correlations were found in the ISACHC I and II groups. A significant negative correlation between serum CRP concentration and the left ventricular ejection fraction (r = - 0.49, P = 0.046) and a significant positive correlation between CRP and the E wave velocity of the mitral valve inflow (r = 0.52, P = 0.046) were found in the ISACHC III group. CONCLUSIONS: The CRP concentration, WBC and NEUT were significantly increased in advanced-stage heart failure patients in comparison with compensated patients and healthy dogs, which indicate the presence of systemic inflammation. However, normal CRP concentration and normal WBC and NEUT can also be present in heart failure. PMID- 29573743 TI - Seroprevalence of Brucella suis in eastern Latvian wild boars (Sus scrofa). AB - Brucellosis due to Brucella suis biovar 2 is one of the most important endemic diseases in wild boar (Sus scrofa) populations in Europe. The aim of the present study was to determine the seroprevalence of brucellosis in wild boars in the eastern part of Latvia. Wild boars killed by hunters in the period from January to April 2015 (n = 877) and from March to April in 2016 (n = 167) were examined for antibodies against B. suis by the Rose Bengal test (RBT), a complement fixation test (CFT), and by enzyme-linked immunosorbent assays. In 2015, 199 samples (22.7%) were positive by RBT and/or CFT while 36 samples (21.6%) were seropositive in 2016. Of the Brucella seropositive samples from 2015 and 2016 (n = 235), 162 (68.9%) were also seropositive to Yersinia enterocolitica. Considering cross-reactivity of serological tests, the seroprevalence of B. suis biovar 2 exposure in wild boars in the eastern part of Latvia was calculated to 14.0% in 2015 and 9.6% in 2016. From selected seropositive samples (42 in 2015 and 36 in 2016) total DNA was extracted and analyzed with an IS711-based nested polymerase chain reaction (PCR) assay. Species and biovar identification was conducted for bacteria isolated in monoculture from PCR positive samples by species specific primers and Bruce-ladder multiplex PCR. Brucella suis biovar 2 was isolated from 12/20 samples in 2015 and 9/9 samples in 2016. The average seroprevalence was relatively low compared to that found in certain other European countries. Males and females had an equal level of seropositivity, but a positive age-trend was observed for both males and females. PMID- 29573744 TI - Optimization of treatment planning workflow and tumor coverage during daily adaptive magnetic resonance image guided radiation therapy (MR-IGRT) of pancreatic cancer. AB - BACKGROUND: To simplify the adaptive treatment planning workflow while achieving the optimal tumor-dose coverage in pancreatic cancer patients undergoing daily adaptive magnetic resonance image guided radiation therapy (MR-IGRT). METHODS: In daily adaptive MR-IGRT, the plan objective function constructed during simulation is used for plan re-optimization throughout the course of treatment. In this study, we have constructed the initial objective functions using two methods for 16 pancreatic cancer patients treated with the ViewRayTM MR-IGRT system: 1) the conventional method that handles the stomach, duodenum, small bowel, and large bowel as separate organs at risk (OARs) and 2) the OAR grouping method. Using OAR grouping, a combined OAR structure that encompasses the portions of these four primary OARs within 3 cm of the planning target volume (PTV) is created. OAR grouping simulation plans were optimized such that the target coverage was comparable to the clinical simulation plan constructed in the conventional manner. In both cases, the initial objective function was then applied to each successive treatment fraction and the plan was re-optimized based on the patient's daily anatomy. OAR grouping plans were compared to conventional plans at each fraction in terms of coverage of the PTV and the optimized PTV (PTV OPT), which is the result of the subtraction of overlapping OAR volumes with an additional margin from the PTV. RESULTS: Plan performance was enhanced across a majority of fractions using OAR grouping. The percentage of the volume of the PTV covered by 95% of the prescribed dose (D95) was improved by an average of 3.87 +/ 4.29% while D95 coverage of the PTV OPT increased by 3.98 +/- 4.97%. Finally, D100 coverage of the PTV demonstrated an average increase of 6.47 +/- 7.16% and a maximum improvement of 20.19%. CONCLUSIONS: In this study, our proposed OAR grouping plans generally outperformed conventional plans, especially when the conventional simulation plan favored or disregarded an OAR through the assignment of distinct weighting parameters relative to the other critical structures. OAR grouping simplifies the MR-IGRT adaptive treatment planning workflow at simulation while demonstrating improved coverage compared to delivered pancreatic cancer treatment plans in daily adaptive radiation therapy. PMID- 29573746 TI - Effects of inter-twin vascular anastomoses of monochorionic twins with selective intrauterine growth restriction on the contents of placental mitochondria DNA. AB - BACKGROUND: Placental mitochondrial DNA (mtDNA) has been proposed to be an indicator for placental hypoxia. This study was designed to evaluate the effect of vascular anastomoses between monochorionic (MC) twins on placental mtDNA. METHODS: In this study, twin-twin transfusion syndrome (TTTS) treated with laser therapy and MC twins without TTTS (without laser therapy) resulting in two live babies were included in this study. The placental mtDNA fold changes (FC) between the small and large twins were analyzed using real-time quantitative PCR. TTTS twins with selective intrauterine growth restriction (sIUGR) are categorized as group 1, TTTS without sIUGR as group 2, MC twins without TTTS but with sIUGR as group 3, and MC twins without both TTTS and sIUGR as group 4. RESULTS: There were seven cases in group 1, eight in group 2, 26 in group 3, and 24 in group 4 cases. The placental mtDNA FC were significantly higher in group 1 (1.57 +/- 0.9) compared to that of the group 3 (0.86 +/- 0.6). CONCLUSION: In MC twin pregnancies with sIUGR, the placental mtDNA FC between the small and large twins are different between cases with and without inter-twin anastomoses. These findings suggest that the inter-twin anastomoses in the MC twins with sIUGR may provide rescue perfusion from the appropriate-for-gestational-age twin to the sIUGR one. PMID- 29573745 TI - Monocular enucleation alters retinal waves in the surviving eye. AB - BACKGROUND: Activity in neurons drives afferent competition that is critical for the refinement of nascent neural circuits. In ferrets, when an eye is lost in early development, surviving retinogeniculate afferents from the spared eye spread across the thalamus in a manner that is dependent on spontaneous retinal activity. However, how this spontaneous activity, also known as retinal waves, might dynamically regulate afferent terminal targeting remains unknown. METHODS: We recorded retinal waves from retinae ex vivo using multi-electrode arrays. Retinae came from ferrets who were binocular or who had one eye surgically removed at birth. Linear mixed effects models were used to investigate the effects of early monocular enucleation on retinal wave activity. RESULTS: When an eye is removed at birth, spontaneous bursts of action potentials by retinal ganglion cells (RGCs) in the surviving eye are shorter in duration. The shortening of RGC burst duration results in decreased pairwise RGC correlations across the retina and is associated with the retinal wave-dependent spread of retinogeniculate afferents previously reported in enucleates. CONCLUSION: Our findings show that removal of the competing eye modulates retinal waves and could underlie the dynamic regulation of competition-based refinement during retinogeniculate development. PMID- 29573747 TI - Implementing the Baby One Program: a qualitative evaluation of family-centred child health promotion in remote Australian Aboriginal communities. AB - BACKGROUND: A healthy start predicts better health in later life. Many remote living Aboriginal and Torres Strait Islander Australian families lack access to consistent, culturally-safe health services. This paper presents a study of implementation of the Baby One Program (BOP). The BOP was designed as a family centred, Indigenous Healthworker-led, home-visiting model of care focused on promoting family health to give children the best start to life. It was developed by Aboriginal community-controlled Apunipima Cape York Health Council and delivered in Queensland Cape York remote communities. We aimed to determine how the BOP was implemented, enablers, strategies used and formative implementation outcomes. METHODS: The qualitative approach utilised theoretical and purposive sampling to explore people's experiences of a program implementation process. Data were generated from semi-structured interviews with four family members enrolled in the BOP and 24 Apunipima staff members. In addition, twenty community members, including two program users, participated in a men's community focus group. The findings are presented according to themes arising from the data. RESULTS: The BOP was rolled out in nine remote Cape York communities between July 2014 and December 2015 and there was high uptake. Indigenous Healthworkers were supported by midwives and maternal and child health nurses to deliver health education to 161 eligible families. The key to effective implementation of family centred care appeared to be the relationships formed between health practitioners, especially Indigenous Healthworkers, and families. The data revealed the following themes: challenging environments for new families and valuing cultural ways, resourcing program delivery, working towards a team approach, negotiating the cultural interface, engaging families, exchanging knowledge through 'yarning', strengthening the workforce, and seeing health changes in families. Healthworker education and training, and knowledge exchange between Healthworkers, midwives and nurses was critical to program effectiveness. The program continues to grow despite substantial logistic, financial and practical challenges. CONCLUSIONS: This study describes an evolving process and explores how health providers connect with families and how the program responds to family and cultural issues. Program development is ongoing; strengthened by more community-level involvement, embedded strategies for ongoing self-evaluation and continuous quality improvements that are responsive to family needs. PMID- 29573748 TI - High serum levels of caspase-cleaved cytokeratin-18 are associated with malignant middle cerebral artery infarction patient mortality. AB - BACKGROUND: There have been found apoptotic changes in brain tissue samples from humans after cerebral ischemia. Caspase-cleaved cytokeratin (CCCK)-18 could appears in blood during apoptosis. High circulating levels of CCCK-18 have been associated with a poor prognosis in patients with cerebral process, such as traumatic brain injury and spontaneous cerebral hemorrhage. However, they have not been explored in patients with ischemic stroke. Thus, the aim of this study was to determine whether there is an association between serum CCCK-18 levels and mortality in patients with severe malignant middle cerebral artery infarction (MMCAI). METHODS: This was an observational, prospective and multicentre study. We included patients with severe MMCAI. We considered MMCAI as severe when Glasgow Coma Scale (GCS) was lower than 9. We measured serum CCCK-18 levels at the diagnosis moment of the severe MMCAI. RESULTS: We found that non-surviving severe MMCAI patients (n = 33) showed lower GCS and platelet count, and higher serum CCCK-18 levels than survivor ones (n = 33). We found an area under the curve (AUC) of serum CCCK-18 levels to predict 30-day mortality of 82% (95% CI = 71%-91%; p < 0.001). In the multiple logistic regression analysis was found that serum CCCK-18 levels were associated with 30-day mortality (OR = 1.023; 95% CI = 1.010-1.037; p = 0.001) after to control for platelet count and GCS. CONCLUSIONS: To our knowledge, this is the first series reporting data on serum CCCK-18 levels in ischemic stroke patients. The novel findings of our study were that non surviving severe MMCAI patients had higher serum CCCK-18 levels than surviving patients, and that there is an association between high serum CCCK-18 levels and MMCAI patients mortality. PMID- 29573749 TI - Central blockade of NLRP3 reduces blood pressure via regulating inflammation microenvironment and neurohormonal excitation in salt-induced prehypertensive rats. AB - BACKGROUND: Inflammation has been implicated in the development of cardiovascular disease. We determined whether nod-like receptor with pyrin domain containing 3 (NLRP3) involved in the process of prehypertension, central blockade of NLRP3 decreased inflammation reaction, regulated neurohormonal excitation, and delayed the progression of prehypertension. METHODS: Prehypertensive rats were induced by 8% salt diet. The rats on high-salt diet for 1 month were administered a specific NLRP3 blocker in the hypothalamic paraventricular nucleus (PVN) for 4 weeks. ELISA, western blotting, immunohistochemistry, and flow cytometry were used to measure NLRP3 cascade proteins, pro-inflammation cytokines (PICs), chemokine ligand 2 (CCL2), C-X-C chemokine receptor type 3 (CXCR3), vascular cell adhesion molecule 1 (VCAM-1), neurotransmitters, and leukocytes count detection, respectively. RESULTS: NLRP3 expression in PVN was increased significantly in prehypertensive rats, accompanied by increased number of microglia, CD4+, CD8+ T cell, and CD8+ microglia. Expressions of PICs, CCL2, CXCR3, and VCAM-1 significantly increased. The balance between 67-kDa isoform of glutamate decarboxylase (GAD67) and tyrosine hydroxylase (TH) was damaged. Plasma norepinephrine (NE) in prehypertensive rats was increased and gamma-aminobutyric acid (GABA) was reduced. NLRP3 blockade significantly decreased blood pressure, reduced PICs, CCL2, VCAM-1 expression in PVN, and restored neurotransmitters. Blood pressure and inflammatory markers were upregulated after termination of central blockage NLRP3. CONCLUSIONS: Salt-induced prehypertension is partly due to the role of NLRP3 in PVN. Blockade of brain NLRP3 attenuates prehypertensive response, possibly via downregulating the cascade reaction triggered by inflammation and restoring the balance of neurotransmitters. PMID- 29573750 TI - Genome-wide association of changes in swine feeding behaviour due to heat stress. AB - BACKGROUND: Heat stress has a negative impact on pork production, particularly during the grow-finish phase. As temperature increases, feeding behaviour changes in order for pigs to decrease heat production. The objective of this study was to identify genetic markers associated with changes in feeding behaviour due to heat stress. Feeding data were collected on 1154 grow-finish pigs using an electronic feeding system from July 2011 to March 2016. In this study, days were classified based on the maximum temperature humidity index (THI) during the day as "Normal" (< 23.33 degrees C), "Alert" (23.33 degrees C <= * < 26.11 degrees C), "Danger" (26.11 degrees C <= * < 28.88 degrees C), and "Emergency" (>= 28.88 degrees C). Six hundred and eighty-one pigs that experienced more than one THI category were genotyped using a variety of SNP platforms, with final genotypes imputed to approximately 60,000 markers. RESULTS: A genome-wide association study (GWAS) for change in feeding behaviour between each pair of THI categories (six pairs) was conducted. Estimates of heritability for differences in feeding activity between each of the THI categories were low (0.02 +/- 0.03) to moderate (0.21 +/- 0.04). Sixty-six associations which explained more than 1% of the genomic variation for a trait were detected across the six GWAS, with the smallest number of associations detected in comparisons with Emergency THI. Gene ontology enrichment analysis showed that biological processes related to immune response and function were over-represented among the genes located in these regions. CONCLUSIONS: Genetic differences exist for changes in feeding behaviour induced by elevated ambient temperatures in grow-finish pigs. Selection for heat tolerant grow-finish pigs should improve production efficiency during warm months in commercial production. Genetic variation in heat shock, stress response and immune function genes may be responsible for the observed differences in performance during heat stress events. PMID- 29573751 TI - A hydatic cyst of the appendix mimicking a uterine lateral mass: a case report. AB - BACKGROUND: Hydatic cyst is a zoonotic disease caused by Echinococcus granulosus. It is a public health problem in Tunisia and remains endemic. It occurs in intra abdominal organs in 10-15% of the cases, particularly in the liver representing the most common affected organ. The aim of the case is to highlight the scarcity of this appendicle origin and to consider it among the differential diagnosis of any intra-abdominal cystic lesion. CASE PRESENTATION: A 45-year-old Tunisian woman, with no past medical history, was admitted for a pelvic cystic mass. The clinical manifestation as well as the imaging findings were toward a lateral uterine mass. Our patient underwent appendectomy and resection of the mass. The patient had no recurrence at 2 years of follow-up. CONCLUSIONS: An extrahepatic hydatid cyst should be recognized among the differential diagnosis of any intra abdominal cystic lesion. Treatment should be based on surgical excision. Due to the risk of recurrence, a close follow-up is mandatory.

PMID- 29573753 TI - Therapeutic Lies in Dementia Care: Should Psychologists Teach Others to be Person Centred Liars? AB - BACKGROUND: Therapeutic lies are frequently used communication strategies, often employed when the person with dementia does not share the same reality as the carer (James and Jackman, 2017; Tuckett 2004; Blum, 1994). Their use is complex and controversial, and a number of protocols have been produced to guide their usage (Mental Health Foundation, 2016). AIMS: The study examined clinicians' perspective on using therapeutic lies in their daily practice and their roles in encouraging the proper use of such a communication strategy. METHOD: This project sampled the views of clinicians, mainly psychologists, before and after attending a workshop on communication in dementia care; they were asked whether psychologists should have a role in teaching others to lie more effectively. RESULTS: It was found that following a comprehensive discussion on the use of lies, the clinicians recognized they lied more than they had originally thought, and were also significantly more supportive of having a role in teaching others to lie effectively. CONCLUSIONS: Clinicians, mainly psychologists, increased their support in the use of therapeutic lying. They considered others would benefit from the psychologists giving supervision in how to lie effectively. PMID- 29573754 TI - Beyond the limits - ECPR in putative fatal circumstances. AB - The eligibility criteria for applying extracorporeal cardiopulmonary resuscitation (ECPR) in patients with cardiac arrest are currently unclear. For those patients with hypothermic cardiac arrest, the European Resuscitation Council (ERC) Guidelines recommend considering ECPR only for patients with potassium <8 mmol/L and a body temperature below 32 degrees C, whereas the American Heart Association Guidelines (AHA) do not express this in a specific manner.We report the case of an urban unwitnessed out-of-hospital cardiac arrest patient found with her head immersed in water at a temperature of 23 degrees C. The patient presented an unclear history and a dire combination of clinical and laboratory parameters (asystole, arterial blood gas: pH 6.8, potassium 8.3 mmol/L, lactate 16.0 mmol/L). Despite these poor prognostic indicators, ECPR was initiated after 95 minutes of CPR and the patient survived with a good neurological outcome.This case highlights the uncertainty in ECPR eligibility and prognostication, especially in those with hypothermia and water immersion for whom aggressive therapies may be warranted. Further data and improved strategies are required to delineate candidacy for this resource-intensive procedure better. PMID- 29573755 TI - Psychometric Properties of the Spanish Version of the Panic Disorder Severity Scale. AB - The Panic Disorder Severity Scale (PDSS) is a well-established measure of panic symptoms but few data exist on this instrument in non north-American samples. Our main goal was to assess the psychometric properties (internal consistency, test re-test reliability, inter-rater reliability, convergent and divergent validity) and the factor structure of the Spanish version. Ninety-four patients with a main diagnosis of panic disorder were assessed with the Spanish version of PDSS, the Anxiety Sensitivity Index-3 (ASI-3), the Panic and Agoraphobia Scale (PAS), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory-II (BDI-II) the PDSS self-rating form and the Clinical Global Impression-Severity scale (CGI). The Spanish PDSS showed acceptable internal consistency (alpha = .74), excellent test retest (total score and items 1-6: alpha > .58, p .90) and medium to large convergent validity (r = .68, 95% CI [.54, .79], p < .01; r = .80, 95% CI [.70, .87], p < .01; r = .48, 95% CI [.28, .67], p < .01; BAI, PAS and ASI-3 total scores respectively). Data on divergent validity (BDI-II total score: r = .52, 95% CI [.34, .67], p < .01) suggest some need for refinement of the PDSS. The confirmatory factor analysis suggested a two-factor modified model for the scale (nested chi2 = 14.01, df = 12, p < .001). The Spanish PDSS has similar psychometric properties as the previous versions and is a useful instrument to assess panic symptoms in clinical settings in Spanish-speaking populations. PMID- 29573756 TI - The effect of docking length on the risk of tail biting, tail-directed behaviour, aggression and activity level of growing pigs kept under commercial conditions. AB - Tail biting in domestic pigs relates to a range of risk factors, primarily in the pigs' environment. Preventive tail docking is widely used, and various experimental approaches suggest that docking reduces the risk of tail biting. However, whether the docking length affects the prevalence of tail biting outbreaks is less studied, as is how a shortened tail will affect pigs' social behaviour. The aim of this study was to investigate how three different tail docking lengths, measured at docking, as well as retained intact tails (Short: 2.9 cm; Medium: 5.7 cm; Long: 7.5 cm; and Undocked) affected tail biting risk and behaviour directed at other finisher pigs with the same docking length treatment. Tail lesions were scored weekly, as was behaviour at pen level after introduction to finisher pens and until a potential outbreak of tail biting or slaughter. Pigs from four commercial herds (258 litters) entered the study. Before the pigs entered the finisher section and data collection started, some pigs were excluded, mainly due to tail biting outbreaks in the weaner section. The risk of a tail biting outbreak differed significantly between treatments (P=0.001), with a lowered risk of a tail biting outbreak in Short pens compared with Undocked (P<0.001) and Medium (P<0.05), and was affected by herd as well (P<0.001). Pens in the Long and Undocked treatments were pooled for the behavioural analysis due to low representation, especially in the Undocked treatment. The probability of tail contacts, where a pig interacted with a pen mate's tail, differed between docking length treatments and was highest in the Long/Undocked compared with the Short treatment (P<0.01), but docking length did not affect aggressive behaviour. Docking length affected the risk of a tail biting outbreak and the frequency of tail-directed behaviour in our participating herds, of which three reported a high prevalence of tail biting problems. Only the shortest docking length treatment (Short) reduced the tail biting risk, but did not completely prevent tail biting outbreaks. PMID- 29573757 TI - The Metacognitive Anger Processing (MAP) Scale - Validation in a Mixed Clinical and a Forensic In-Patient Sample. AB - BACKGROUND: The metacognitive approach by Wells and colleagues has gained empirical support with a broad range of symptoms. The Metacognitive Anger Processing (MAP) scale was developed to provide a metacognitive measure on anger (Moeller, 2016). In the preliminary validation, three components were identified (positive beliefs, negative beliefs and rumination) to be positively correlated with the anger. AIMS: To validate the MAP in a sample of mixed clinical patients (n = 88) and a sample of male forensic patients (n = 54). METHOD: The MAP was administered together with measures of metacognition, anger, rumination, anxiety and depressive symptoms. RESULTS: The MAP showed acceptable scalability and excellent reliability. Convergent validity was evidenced using the general metacognitive measure (MCQ-30), and concurrent validity was supported using two different anger measures (STAXI-2 and NAS). CONCLUSIONS: The MAP has promising potential to assess anger regulation problems by providing a framework on angry rumination as well as the belief structures that proposedly drive the selection of this maladaptive processing strategy as suggested in the metacognitive model. These findings may have implications for clinical interventions. For example, conducting functional analyses on anger rumination could increase the understanding of dysregulated anger processing and lead to new interventions focused on shifting thinking style. PMID- 29573758 TI - Age-related and photoperiodic variation of the DAZ gene family in the testis of the Syrian hamster (Mesocricetus auratus). AB - SummaryThe Deleted in AZoospermia (DAZ) gene family regulates the development, maturation and maintenance of germ cells and spermatogenesis in mammals. The DAZ family consists of two autosomal genes, Boule and Dazl (Daz-like), and the Daz gene on chromosome Y. The aim of this study was to analyze the localization of DAZL and BOULE during testicular ontogeny of the seasonal-breeding Syrian hamster, Mesocricetus auratus. We also evaluated the testicular expression of DAZ family genes under short- or long-photoperiod conditions. In the pre-pubertal and adult testis, DAZL protein was found mainly in spermatogonia. BOULE was found in the spermatogonia from 20 days of age and during the pre-pubertal and adult period it was also detected in spermatocytes and round spermatids. DAZL and BOULE expression in spermatogonia was strictly nuclear only in 20-day-old hamsters. We also detected the novel mRNA and protein expression of BOULE in Leydig cells. In adult hamsters, Dazl expression was increased in regressed testis compared with non-regressed testis and DAZL protein expression was restricted to primary spermatocytes in regressed testis. These results show that DAZL and BOULE are expressed in spermatogonia at early stages in the Syrian hamster, then both proteins translocate to the cytoplasm when meiosis starts. In the adult regressed testis, the absence of DAZL in spermatogonia might be related to the decrease in germ cell number, suggesting that DAZ gene family expression is involved in changes in seminiferous epithelium during photoregression. PMID- 29573759 TI - Executive Dysfunction and Depression in Pediatric Temporal Lobe Epilepsy: The Contribution of Hippocampal Sclerosis and Psychosocial Factors. AB - OBJECTIVES: Temporal lobe epilepsy (TLE) has been identified as a risk factor for increased depression features in children and adolescents; however, less is known regarding specific neurocognitive predictors of depression in this population above and beyond seizure-specific and sociodemographic factors. METHODS: The study included 62 patients with TLE (64% male) aged 8 to 16 years (M=12.62; SD=2.26) who underwent comprehensive neuropsychological evaluation. RESULTS: Correlation analyses revealed significant association between patient depression and WCST Total Perseverations, BRIEF Behavioral Regulation Index (BRI) and family stress. Perseverative errors on the WCST and the BRI were found to significantly predict depression features in youth with TLE. Patient performance on WCST was also found to fully mediate the significant relationship between hippocampal sclerosis (HS) and depression in pediatric TLE. Finally, logistic regression indicated HS in the presence of TLE was associated with a four-fold risk of clinically significant depression ratings. CONCLUSIONS: The current findings offer strong support for the relationship between executive function (EF) and depression in pediatric TLE. Also, as HS is not modifiable, these findings suggest EF intervention may be a potential modality for improving health-related quality of life (HRQOL) in youth with TLE. (JINS, 2018, 24, 606-616).

AB - INTRODUCTION: Hepatic transarterial chemoembolization is a widely used technique for the treatment of hepatocellular carcinoma. The most common complication of this procedure is postembolization syndrome. The main objective of this study was to assess risk factors for the development of postembolization syndrome. MATERIAL AND METHODS: Single-centre retrospective analysis of 563 hepatic transarterial chemoembolization procedures from January 1st, 2014 - December 31st, 2015. Hepatic transarterial chemoembolization was performed with 1/2 - 2 vials of 100 - 300 MUm microspheres loaded with doxorubicin. Patients who experienced postembolization syndrome were identified based on prolongation of hospitalization due to pain, fever, nausea and/or vomiting. A control group with the patients who did not have postembolization syndrome was randomly created (three controls for one case). Descriptive analysis and multivariate logistic regression were performed. RESULTS: The overall prevalence of postembolization syndrome was 6.2%. Hepatic transarterial chemoembolization with doxorubicin dosage above 75 mg (more than one vial), the size of the largest nodule and female gender had statistically significant relation with development of postembolization syndrome (p = 0.030, p = 0.046 and p = 0.037, respectively). DISCUSSION: Doxorrubicin dosage above 75 mg is associated with a higher risk of postembolization syndrome. This result can be helpful for decision-making in clinical practice, whenever it is possible to avoid a higher dose without compromising the efficacy of the treatment. The size of the largest nodule and female gender also constitute risk factors for postembolization syndrome. The other variables studied were not related to the development of postembolization syndrome. CONCLUSION: The dose of doxorrubicin, the size of the largest nodule treated and female gender are potential risk factors for the development of postembolization syndrome after hepatic transarterial chemoembolization for hepatocellular carcinoma. PMID- 29573764 TI - Clinical Guidelines and Implementation into Daily Dental Practice. AB - INTRODUCTION: The purpose of this study is to assess the extent of the familiarity, attitude and perceptions of dental professionals regarding clinical dental guidelines and their implementation into daily dental practice. MATERIAL AND METHODS: For this purpose, a questionnaire which was developed by the members of the World Dental Federation, European Regional Organization Working Group - 'Relation Between Dental Practitioner and Universities', was implemented by the National Dental Associations of six European Regional Organization-zone countries (Georgian Stomatological Association - Georgia, Associazione Nazionale Dentisti Italiani - Italy, Portuguese Dental Association - Portugal, Russian Dental Association - Russia, Swiss Dental Association - Switzerland, and Turkish Dental Association - Turkey. The questionnaire was filled by a total of 910 dental professionals who are members of one of these national dental associations and who voluntarily wanted to participate to this survey. RESULTS: Most of the survey participants were familiar with clinical dental guidelines (68%), claimed that they implemented them into daily practice (61.7%), and generally acknowledged their benefits (81.8%). Many participants believed that clinical dental guidelines could help to improve the clinical treatment plan (50.6 %) and the accuracy of diagnosis (39.4%); which increased with age and years of practice (p < 0.05). The most frequently perceived barrier to the effective implementation of clinical dental guidelines was expressed as 'lack of awareness', while participants suggested a role for national dental associations in spreading clinical dental guidelines. DISCUSSION: A better understanding of the perceptions and attitudes of dentists towards clinical dental guidelines and the potential impact of factors affecting such perceptions and attitudes may be of particular importance for attempts aiming at overcoming the barriers for effective implementation of clinical dental guidelines into daily practice. CONCLUSION: Despite a significant familiarity and a common positive attitude, dental professionals are likely to have different perceptions towards clinical dental guidelines, especially regarding their effective implementation into daily practice, benefits and barriers.

AB - INTRODUCTION: Quality of life is an important measure for health-outcome evaluation. Although otitis media is one of the most common childhood diseases, its impact on Portuguese children's quality of life is unknown. The aim of this study is to determine the quality of life of Portuguese children with chronic otitis media with effusion and/or recurrent acute otitis media and the short-term impact of transtympanic ventilation tubes, using the Portuguese version of the OM 6 questionnaire, a valid, reliable and sensitive instrument to evaluate the health-related quality of life in children with otitis media. MATERIAL AND METHODS: This study was conducted in a tertiary referral center, to where children are referred from primary care and hospital pediatric consultations. The Portuguese version of the OM-6 questionnaire was applied to children with chronic otitis media with effusion and/or recurrent acute otitis media. The instrument was re-administered at two months postoperatively to a group of children who underwent tympanostomy tube placement, to evaluate the change in quality of life with the surgical procedure. RESULTS: The study involved a sample of 169 children, aged between 6 months and 12 years (mean: 4.20 +/- 2.05 years). The average score in the survey was 3.3 +/- 1.47, of a maximum of 7 (worst quality of life). The domains 'caregiver concerns', 'hearing loss' and 'physical suffering' had the highest scores. The domain 'hearing loss' was correlated with the domain 'speech impairment' (rs = 0.41; p < 0.001) and the domain 'physical suffering' correlated with the domain 'activity limitation' (rs = 0.47; p < 0.001). There was a correlation between the score on 'hearing loss' and the presence of conduction hearing loss (chi2 (6) = 24.662; p = 0.022). Children with chronic otitis media with effusion had lower scores on the domain 'physical suffering', while children with recurrent acute otitis media had lower scores in the domain 'hearing loss' and higher scores in the domain 'emotional distress'. There was an improvement in the quality of life in all the dimensions studied by the questionnaire after surgery. The improvement was large in 55%, moderate in 15% and small in 10% of the cases. The presence of otorrhea postoperatively did not decrease the quality of life improvement achieved with surgery. CONCLUSION: Otitis media has a negative impact on Portuguese children quality of life. Tympanostomy tubes improve quality of life related to the middle ear in most children. The application of validated disease-specific questionnaires allows an enhanced understanding of the impact of otitis media on Portuguese children quality of life and of the success of therapeutic measures.

AB - INTRODUCTION: Suicide is considered a public health priority. It is a complex phenomenon resulting from the interaction of several factors, which do not depend solely on individual conditions. This study analyzes the spatio-temporal evolution of suicide mortality between 1980 and 2015, identifying areas of high risk, and their variation, in the 278 municipalities of Continental Portugal. MATERIAL AND METHODS: Based on the number of self-inflicted injuries and deaths from suicide and the resident population, the spatio-temporal evolution of the suicide mortality rate was assessed via: i) a Poisson joinpoint regression model, and ii) spatio-temporal clustering methods. RESULTS: The suicide mortality rate evolution showed statistically significant increases over three periods (1980 - 1984; 1999 - 2002 and 2006 - 2015) and two statistically significant periods of decrease (1984 - 1995 and 1995 - 1999). The spatio-temporal analysis identified five clusters of high suicide risk (relative risk >1) and four clusters of low suicide risk (relative risk < 1). DISCUSSION: The periods when suicide mortality increases seem to overlap with times of economic and financial instability. The geographical pattern of suicide risk has changed: presently, the suicide rates from the municipalities in the Center and North are showing more similarity with those seen in the South, thus increasing the ruralization of the phenomenon of suicide. CONCLUSION: Between 1980 and 2015 the spacio-temporal pattern of mortality from suicide has been changing and is a phenomenon that is currently experiencing a growing trend (since 2006) and is of higher risk in rural areas. PMID- 29573768 TI - Factors Influencing the Implementation of Screening and Brief Interventions for Alcohol Use in Primary Care Practices: A Systematic Review Protocol. AB - INTRODUCTION: Alcohol is a leading risk factor contributing to the global burden of disease. National and international agencies recommend evidence-based screening and brief interventions in primary care settings in order to reduce alcohol consumption. However, the majority of primary care professionals do not routinely deliver such interventions. OBJECTIVE: To identify factors influencing general practitioners/family physicians' and primary care nurses' routine delivery of alcohol screening and brief intervention in adults. MATERIAL AND METHODS: A systematic literature search will be carried out in the following electronic databases: Medline, CINAHL, CENTRAL, and PsycINFO. Two authors will independently abstract data and assess study quality using the NIH National Heart, Lung, and Blood Institute quality assessment tools for quantitative studies, and the CASP checklist for qualitative studies. A narrative synthesis of the findings will be provided, structured around the barriers and facilitators identified. Identified barriers and facilitators will be further analysed using the Behavioural Change Wheel/Theoretical Domains Framework. DISCUSSION: This review will describe the barriers to, and facilitators for, the implementation of alcohol screening and brief interventions by general practitioners/family physicians and nurses at primary care practices. By mapping the barriers and facilitators to the domains of the Behavioural Change Wheel/Theoretical Domains Framework, this review will also provide implementation researchers with a useful tool for selecting promising practitioner-oriented behavioural interventions for improving alcohol screening and brief intervention delivery in primary care. CONCLUSION: This review will provide important information for implementing alcohol screening and brief intervention in primary health care.Systematic Review Registration: PROSPERO CRD42016052681.

MATERIAL AND METHODS: We present a brief literature review of the definition, pathophysiology, aetiology, diagnosis, prevention and treatment of delirium and its social and economic impact. RESULTS AND DISCUSSION: Delirium is under-recognized, especially by health professionals, and is associated with higher morbidity, mortality and economic burden. Moreover, the presence of delirium interferes with the evaluation and approach to other symptoms. Furthermore, it causes significant distress in patient's families and health professionals. The best treatment for delirium is prevention which is based on multidisciplinary interventions that addresses the main risk factors. The scientific evidence for the treatment of delirium is scarce. Non pharmacological approaches are usually the first choice, and includes environmental, behavioural and social strategies. Pharmacological options, mainly antipsychotics, are a second-line treatment used essentially to prevent self harm. CONCLUSION: The recognition and prevention of delirium are crucial. Health professional education and training, patient clinical monitoring and families support are mandatory. Considering the impact of delirium on patients, relatives, health services and professionals we must be more aware of delirium and, why not, make it the 7th vital sign.

AB - Hidrosadenitis supurativa is a chronic inflammatory disease with great physical and psychological impact. Although conservative treatments may be effective in mild forms of the disease, extensive surgical resection and reconstruction are necessary in more severe forms of the disease. The purpose of this paper is to describe our two-stage reconstructive procedure regarding this kind of disease. We present a clinical case of a patient with severe, bilateral axillary hidrosadenitis. In the first surgical step we excised the lesions and applied the artificial dermis secured with negative pressure wound therapy. In the second step we used a split thickness skin graft to close the wound and again applied negative pressure wound therapy. The graft take was very good, without complications. The cosmetic outcome is acceptable and shoulder mobility was not compromised. No recurrence was detected (nine months follow up). PMID- 29573771 TI - Radiofrequency for Treatment of Refractory Epistaxis in Hereditary Hemorrhagic Telangiectasia. AB - Hereditary hemorrhagic telangiectasia is a rare multi-systemic autosomal dominant disorder characterized by dysplasia of the vascular connective tissue and recurrent bleeding tendency. Epistaxis is the most common and earliest symptom. It is usually mild to moderate, however, in some patients it can be severe with significant interference in quality of life. We report a case of a patient with hereditary hemorrhagic telangiectasia, in which an episode of refractory epistaxis was treated with radiofrequency and fibrin sealant. Control of acute bleeding and elimination of telangiectasia was possible with this technique. After six months follow-up, there was no epistaxis recurrence. Various treatments for epistaxis in this disease have been described in the literature, but there is no consensus about the gold-standard procedure. Radiofrequency ablation of telangiectasia is a recent technique that has shown to be safe, effective and well tolerated, even in patients who underwent other previous treatments.

AB - BACKGROUND AND OBJECTIVES: We have previously indicated that EGFR has a role in carcinogenesis in a subgroup of sinonasal squamous cell carcinomas (SNSCC). In addition, EGFR activates 2 of the most important intracellular signalling pathways: PI3K/pAKT/mTOR/pS6 and MAP pathway kinases. The objective of this study was to evaluate the involvement of the EGFR/PI3K/pAKT/mTOR/pS6 pathway and its relationship with clinical-pathological parameters and follow-up of sinonasal squamous cell carcinoma. MATERIAL AND METHODS: The immunohistochemical expression of different components of the PI3K/AKT/mTOR/pS6 pathway and its relationship with various clinical-pathological parameters was studied in a series of 54 patients with SNSCC. RESULTS: Loss of PTEN expression was observed in 33/54 cases (61%) and pAKT, mTOR and pS6 pre-expression was observed in 19/54 cases (35%), 8/54 cases (15%), and 47/54 cases (87%), respectively. Loss of PTEN expression was related to intracranial invasion and development of regional metastases (p=0.005). Overexpression of pS6 was associated with a decrease in survival (p=0.008), presence of local recurrences (p=0.055), and worsening of overall prognosis (p=0.007). No significant relationships were observed between pAKT and mTOR expression and the clinicopathological parameters studied. CONCLUSIONS: Alterations in the expression of EGFR/PI3K/pAKT/mTOR/pS6 pathway components are common in a subgroup of SNSCC. This study reveals that the absence of pS6 overexpression is associated with better clinical outcomes. Therefore, pS6 expression could be considered as an unfavourable prognostic marker.

PMID- 29573783 TI - Development of a fast and simple gas chromatographic protocol based on the combined use of alkyl chloroformate and solid phase microextraction for the assay of polyamines in human urine. AB - Polyamines are aliphatic amines with low molecular weight that are widely recognized as one of the most important cancer biomarkers for early diagnosis and treatment. The goal of the work herein presented is the development of a rapid and simple method for the quantification of free polyamines (i.e., putrescine, cadaverine, spermidine, spermine) and N-monoacetylated polyamines (i.e., N1 Acetylspermidine, N8-Acetylspermidine, and N1-Acetylspermine) in human urine. A preliminary derivatization with propyl chloroformate combined with the use of solid phase microextraction (SPME) allowed for an easy and automatable protocol involving minimal sample handling and no consumption of organic solvents. The affinity of the analytes toward five commercial SPME coatings was evaluated in univariate mode, and the best result in terms of analyte extraction was achieved using the divinylbenzene/carboxen/polydimethylsiloxane fiber. The variables affecting the performance of SPME analysis were optimized by the multivariate approach of experimental design and, in particular, using a central composite design (CCD). The optimal working conditions in terms of response values are the following: extraction temperature 40 degrees C, extraction time of 15 min and no addition of NaCl. Analyses were carried out by gas chromatography-triple quadrupole mass spectrometry (GC-QqQ-MS) in selected reaction monitoring (SRM) acquisition mode. The developed method was validated according to the guidelines issued by the Food and Drug Administration (FDA). The satisfactory performances reached in terms of linearity, sensitivity (LOQs between 0.01 and 0.1 MUg/mL), matrix effect (68-121%), accuracy, and precision (inter-day values between -24% and +16% and in the range 3.3-28.4%, respectively) make the proposed protocol suitable to be adopted for quantification of these important biomarkers in urine samples. PMID- 29573784 TI - Supercritical fluid chromatography versus high performance liquid chromatography for enantiomeric and diastereoisomeric separations on coated polysaccharides based stationary phases: Application to dihydropyridone derivatives. AB - For analytical applications, SFC has always remained in the shadow of LC. Analytical enantioseparation of eight dihydropyridone derivatives, was run in both High Performance Liquid Chromatography and Supercritical Fluid Chromatography. Four polysaccharide based chiral stationary phases namely amylose and cellulose tris(3, 5-dimethylphenylcarbamate), amylose tris((S)-alpha phenylethylcarbamate) and cellulose tris(4-methylbenzoate) with four mobile phases consisted of either n-hexane/ethanol or propan-2-ol (80:20 v:v) or carbon dioxide/ethanol or propan-2-ol (80:20 v:v) mixtures were investigated under same operatory conditions (temperature and flow-rate). The elution strength, enantioselectivity and resolution were compared in the two methodologies. For these compounds, for most of the conditions, HPLC afforded shorter retention times and a higher resolution than SFC. HPLC appears particularly suitable for the separation of the compounds bearing two chiral centers. For instance compound 7 was baseline resolved on OD-H CSP under n-Hex/EtOH 80/20, with resolution values equal to 2.98, 1.55, 4.52, between the four stereoisomers in less than 17 min, whereas in SFC, this latter is not fully separated in 23 min under similar eluting conditions. After analytical screenings, the best conditions were transposed to semi-preparative scale.

PMID- 29573786 TI - What the radiologist should know about postoperative MDCT evaluation of a patient treated with cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy. AB - Cytoreductive surgery (CRS), often associated with hyperthermic intraperitoneal chemotherapy (HIPEC), is now a well-recognised treatment for most peritoneal malignancies in selected patients. As imaging is frequently performed postoperatively, radiologists are increasingly confronted with postoperative multidetector-row computed tomography (MDCT) examinations in these cases. In this article, after briefly describing the procedures that are currently being performed for the treatment of peritoneal metastases, the normal postoperative MDCT changes that may be encountered after these procedures are described. We then highlight complications that may arise after CRS, depending on the surgery performed, and those related to HIPEC, and illustrate their MDCT features. PMID- 29573787 TI - Tumour motion of oesophageal squamous cell carcinoma evaluated by cine MRI: associated with tumour location. AB - AIM: To evaluate the association between oesophageal tumour motion and tumour location using cine magnetic resonance imaging (MRI). MATERIALS AND METHODS: Thirty-three consecutive patients with oesophageal squamous cell carcinoma were enrolled, and underwent cine MRI of oesophageal tumours. The maximum displacements in the anterior-posterior (A-P), superior-inferior (S-I), and left right (L-R) directions of the tumours were assessed statistically to show their associations with tumour location. RESULTS: Tumour motion in A-P and S-I directions increased from upper to lower oesophagus (r=0.505, p=0.003; and r=0.600, p<0.001, respectively). In A-P and S-I directions, tumours showed larger motion in the lower oesophagus than in the upper or middle oesophagus (all p<0.05). Motion of middle and lower oesophageal tumours in the S-I direction was larger than in L-R or A-P direction (all p<0.05). To provide 95% geometric coverage for the motion of upper oesophageal tumours, statistical analysis showed margins of 3.75 mm in L-R direction, 3.72 mm in A-P direction, and 5.38 mm in S-I direction. For the motion of tumours of the middle oesophagus, 95% coverage required margins of 8.50, 6.62, and 11.96 mm in L-R, A-P, and S-I directions, respectively, and for lower oesophageal tumours, 95% coverage required margins of 9.17, 9.68, and 12.98 mm in L-R, A-P, and S-I direction, respectively. CONCLUSION: Oesophageal tumour motion in different directions can be associated with tumour location as shown on cine MRI, suggesting that the present findings could be helpful for better understanding oesophageal tumour motion and gating individualised radiation delivery strategies.

AB - ERAS is a multimodal perioperative care program which replaces traditional practices concerning analgesia, intravenous fluids, nutrition, mobilization as well as a number of other perioperative items, whose implementation is supported by evidence-based best practices. According to the RICA guidelines published in 2015, a review of the literature and the consensus established at a multidisciplinary meeting in 2015, we present a protocol that contains the basic procedures of an ERAS pathway for resective esophageal surgery. The measures involved in this ERAS pathway are structured into 3areas: preoperative, perioperative and postoperative. The consensus document integrates all the analyzed items in a unique time chart. ERAS programs in esophageal resection surgery can reduce postoperative morbidity, mortality, hospitalization and hospital costs.

AB - This study was conducted to investigate the use of Alpha 1-antitrypsin (AAT) to inhibit microglia activation in chronic hypertension model and provide a permissive environment for stem cell transplantation. Chronic ocular hypertension of C57BL/6 mice using magnetic microbead injection was induced 3 weeks prior to iPSCs transplantation. The ocular hypertension model was assessed histologically and intraocular pressure was measured. Survival of grafted cells and microglia activation were examined by flow cytometry and immunofluorescence in AAT and PBS treated hosts. Retinal cytokines expression was also detected by real-time PCR. Chronic ocular hypertension resulted in persistent microglia activation and stem cell grafts loss. AAT treatment significantly inhibited microglia activation and facilitated the survival of transplant iPSCs 4w post transplantation compared to PBS treatment. AAT holds tremendous potential for the clinical application to control neuroinflammation factor in glaucoma and improve the stem cell replacement therapy of retinal neurodegenerative disease.

Could MAA be defined as a solution for immunotherapy funding by French health system?] AB - Over the last few years, many therapeutic innovations have been approved and marketed in France, within a strained financial setting. Legal dispositions allowed manufacturers (LEEM - les enterprises du medicament) and the economic committee for health products (CEPS) to contract various confidential market access agreements to contain health product expenses. The purposes of this article are to define and describe these different existing market access agreements and to open discussion on their applicability to the problematic of immune-oncology drugs financing. Financial agreements, which led to major savings (discounts refunded to the public payer), have not responded completely to the therapeutic innovations financing problems. Performance agreements (funding based on real-life data and effectiveness of the drug) constitute a hope for health products financing, but major methodological challenges for their use in routine restrict them to rare cases only today. Even though several financial agreements could partly respond to this problematic, use of performance agreements could really constitute an interesting track to tackle this issue.

AB - Epidemiologic and genetic studies suggest common environmental and genetic risk factors for a number of psychiatric disorders, including depression, bipolar disorder, and schizophrenia. Genetic and environmental factors, especially adverse life events, not only have main effects on disease development but also may interact to shape risk and resilience. Such gene by adversity interactions have been described for FKBP5, an endogenous regulator of the stress neuroendocrine system, conferring risk for a number of psychiatric disorders. In this review, we present a molecular and cellular model of the consequences of FKBP5 by early adversity interactions. We illustrate how altered genetic and epigenetic regulation of FKBP5 may contribute to disease risk by covering evidence from clinical and preclinical studies of FKBP5 dysregulation, known cell type and tissue-type expression patterns of FKBP5 in humans and animals, and the role of FKBP5 as a stress-responsive molecular hub modulating many cellular pathways. FKBP5 presents the possibility to better understand the molecular and cellular factors contributing to a disease-relevant gene by environment interaction, with implications for the development of biomarkers and interventions for psychiatric disorders. PMID- 29573792 TI - In situ comparison of A-mode ultrasound tracking system and skin-mounted markers for measuring kinematics of the lower extremity. AB - Skin-mounted marker based motion capture systems are widely used in measuring the movement of human joints. Kinematic measurements associated with skin-mounted markers are subject to soft tissue artifacts (STA), since the markers follow skin movement, thus generating errors when used to represent motions of underlying bone segments. We present a novel ultrasound tracking system that is capable of directly measuring tibial and femoral bone surfaces during dynamic motions, and subsequently measuring six-degree-of-freedom (6-DOF) tibiofemoral kinematics. The aim of this study is to quantitatively compare the accuracy of tibiofemoral kinematics estimated by the ultrasound tracking system and by a conventional skin mounted marker based motion capture system in a cadaveric experimental scenario. Two typical tibiofemoral joint models (spherical and hinge models) were used to derive relevant kinematic outcomes. Intra-cortical bone pins equipped with optical markers were inserted in the tibial and femoral bones to serve as a reference to provide ground truth kinematics. The ultrasound tracking system resulted in lower kinematic errors than the skin-mounted markers (the ultrasound tracking system: maximum root-mean-square (RMS) error 3.44 degrees for rotations and 4.88 mm for translations, skin-mounted markers with the spherical joint model: 6.32 degrees and 6.26 mm, the hinge model: 6.38 degrees and 6.52 mm). Our proposed ultrasound tracking system has the potential of measuring direct bone kinematics, thereby mitigating the influence and propagation of STA. Consequently, this technique could be considered as an alternative method for measuring 6-DOF tibiofemoral kinematics, which may be adopted in gait analysis and clinical practice. PMID- 29573793 TI - Effect of stable and unstable load carriage on walking gait variability, dynamic stability and muscle activity of older adults. AB - Load carriage perturbs the neuromuscular system, which can be impaired due to ageing. The ability to counteract perturbations is an indicator of neuromuscular function but if the response is insufficient the risk of falls will increase. However, it is unknown how load carriage affects older adults. Fourteen older adults (65 +/- 6 years) attended a single visit during which they performed 4 min of walking in 3 conditions, unloaded, stable backpack load and unstable backpack load. During each walking trial, 3-dimensional kinematics of the lower limb and trunk movements and electromyographic activity of 6 lower limb muscles were recorded. The local dynamic stability (local divergence exponents), joint angle variability and spatio-temporal variability were determined along with muscle activation magnitudes. Medio-lateral dynamic stability was lower (p = 0.018) and step width (p = 0.019) and step width variability (p = 0.015) were greater in unstable load walking and step width variability was greater in stable load walking (p = 0.009) compared to unloaded walking. However, there was no effect on joint angle variability. Unstable load carriage increased activity of the Rectus Femoris (p = 0.001) and Soleus (p = 0.043) and stable load carriage increased Rectus Femoris activity (p = 0.006). These results suggest that loaded walking alters the gait of older adults and that unstable load carriage reduces dynamic stability compared to unloaded walking. This can potentially increase the risk of falls, but also offers the potential to use unstable loads as part of fall prevention programmes. PMID- 29573794 TI - The effect of static neck flexion on mechanical and neuromuscular behaviors of the cervical spine. AB - Occupations that involve sustained or repetitive neck flexion are associated with a higher incidence of neck pain. Little in vivo information is available on the impact of static neck flexion on cervical spinal tissue. The aim of this study was to assess changes in mechanical and neuromuscular behaviors to sustained neck flexion in healthy adults. Sixty healthy subjects aged 20-35 years participated in this study. The participants were exposed to static neck flexion at a fixed angle of full flexion for 10 min. Mechanical and neuromuscular responses of the cervical spine to sudden perturbations were measured pre- and post-exposure. Magnitude of load-relaxation during flexion exposure, stiffness, peak head angular velocity, and reflexive activities of cervical muscles were recorded. Effective neck stiffness decreased significantly, especially in female participants (P = 0.0001). The reflexive response of the cervical erector spinae muscles to head perturbation delayed significantly (P = 0.0001). Peak head angular velocity was significantly increased after exposure to neck flexion for 10 min, especially in female participants (P = 0.001). In the present study, static flexion resulted in changes in mechanical and neuromuscular behavior of the cervical spine, potentially leading to decreased stiffness of the cervical spine. The results confirm the importance of maintaining a correct head and neck position during work and improving the work environment to reduce the cervical spinal load and work-related neck pain. PMID- 29573795 TI - Effects of gamma radiation on microbial, physicochemical, and structural properties of whey protein model system. AB - Gamma radiation has been used in food processing for many years, though it has certain effects on food components. Whey protein solutions (10%/30%, wt/vol) were treated with gamma radiation at various dosages (10-25 kGy) and evaluated for microbial changes in the solutions and physicochemical and structural changes of whey proteins. Whey protein solutions after gamma radiation showed substantially lower populations of all viable microorganisms than those of controls. The 10% whey protein solution treated at radiation of 20 or 25 kGy remained sterile for up to 4 wk at room temperature. Gamma radiation increased viscosity and turbidity and decreased soluble nitrogen of whey protein solutions compared to nonradiated control samples regardless of radiation dosage. Nonreducing sodium dodecyl sulfate-PAGE suggested that whey proteins under gamma radiation treatment formed aggregates with high molecular weights. Reducing sodium dodecyl sulfate-PAGE showed that disulfide bonds played a role in gamma radiation-induced whey protein cross-linking. Scanning and transmission electron microscopy micrographs exhibited large aggregates of whey proteins after gamma radiation treatment. Results suggested that gamma radiation could be applied to whey protein solution for purposes of reducing microbial counts and cross-linking protein molecules. PMID- 29573796 TI - Evaluation of alternatives to cautery disbudding of dairy goat kids using physiological measures of immediate and longer-term pain. AB - We evaluated alternatives to cautery disbudding of goat kids using physiological measures of immediate and longer-term pain. Fifty Saanen doe kids were randomly assigned to 1 of 5 treatments (n = 10/treatment): (1) cautery disbudding (CAUT), (2) caustic paste disbudding (CASP), (3) liquid nitrogen disbudding (CRYO), (4) clove oil injected into the horn bud (CLOV), or (5) sham disbudding (SHAM). Serum cortisol and haptoglobin concentrations were measured from blood samples collected immediately before treatment (baseline) and at 15, 30, 60, and 120 min and then again at 6 and 24 h post-treatment. An infrared thermography camera was used to take images of the horn buds 24 h pre- and 24, 48, and 72 h post treatment to measure skin temperature. Body weight was measured daily for 1 wk to assess weight change post-treatment. Images of the horn buds were taken at d 1, 2, and 7 and at 6 wk post-treatment to assess tissue damage and wound healing. Mean cortisol concentrations were elevated in CASP kids 1 h post-treatment relative to CAUT kids. Cortisol concentrations of CRYO kids were higher than those of CAUT kids 30 min post-treatment; concentrations for CLOV kids were similar to CAUT kids post-treatment. Mean haptoglobin concentrations were similar across treatments over time; however, CLOV kids had higher concentrations at 24 h post-treatment than all other treatments. Skin temperatures of CASP and CLOV kids were elevated relative to CAUT kids at all time points post-treatment, and all disbudded kids had skin temperatures above those of SHAM kids at 72 h post treatment. Treatment did not influence weight gain. The CAUT kids had large, open wounds exposing bone; small scabs were still evident 6 wk post-treatment. The CASP kids had red and open, raw wounds that generated large eschars, apparent for up to 6 wk. The CRYO kids had closed, dry wounds initially, but over time lesions appeared that caused open wounds; small scabs were present 6 wk post-treatment. The CLOV kids had closed, dry wounds with blackened skin; healed skin and minimal scabs were present 6 wk post-treatment. Caustic paste and cryosurgical disbudding appeared to cause more pain compared with cautery disbudding; thus, these methods may not provide good alternatives to cautery disbudding. Clove oil appeared to cause a similar pain response as cautery disbudding and smaller wounds with earlier tissue repair; this method shows promise as an alternative to cautery disbudding. PMID- 29573797 TI - Genome-wide association mapping for type and mammary health traits in French dairy goats identifies a pleiotropic region on chromosome 19 in the Saanen breed. AB - Type traits and mammary health traits are important to dairy ruminant breeding because they influence animal health, milking ability, and longevity, as well as the economic sustainability of farms. The availability of the genomic sequence and a single nucleotide polymorphism chip in goats has opened up new fields of investigation to better understand the genes and mechanisms that underlie such complex traits and to be able to select them. Our objective was to perform a genome-wide association study in dairy goats for 11 type traits and somatic cell count (SCC) as proxies for mastitis resistance. A genome-wide association study was implemented using a daughter design composed of 1,941 Alpine and Saanen goats sired by 20 artificial insemination bucks, genotyped with the Illumina GoatSNP50 BeadChip (Illumina Inc., San Diego, CA). This association study was based on both linkage analyses and linkage disequilibrium using QTLmap software (http://dga7.jouy.inra.fr/qtlmap/) interval mapping was performed with the likelihood ratio test using linear regressions. Breeds were analyzed together and separately. The study highlighted 37 chromosome-wide significant quantitative trait loci (QTL) with linkage analyses and 222 genome-wide significant QTL for linkage disequilibrium, for type and SCC traits in dairy goats. Genomic control of those traits was mostly polygenic and breed-specific, suggesting that within breed selection would be favored for those traits. Of note, Capra hircus autosome (CHI) 19 appeared to be highly enriched in single nucleotide polymorphisms associated with type and SCC, with 2 highly significant regions in the Saanen breed. One region (33-42 Mb) was significantly associated with SCC and includes candidate genes associated with response to intramammary infections (RARA, STAT3, STAT5A, and STAT5B). Another region of the CHI 19 (24.5-27 Mb) exhibited an adverse pleiotropic effect on milk production (milk, fat yield, and protein yield) and udder traits (udder floor position and rear udder attachment) that agreed with the negative genetic correlations that exist between those 2 groups of traits. These QTL were not found in the Alpine breed. In Alpine, the 2 most significant regions were associated with chest depth on CHI 6 (45.8-46.0 Mb) and CHI 8 (80.7-81.1 Mb). These results will be helpful for goat selection in the future and could lead to identification of causal mutations. PMID- 29573798 TI - Nuclear factor erythroid 2-related factor 2 antioxidant response element pathways protect bovine mammary epithelial cells against H2O2-induced oxidative damage in vitro. AB - The experiment was conducted to determine the role of nuclear factor (erythroid derived 2)-like factor 2 (NFE2L2, formerly Nrf2) antioxidant response element (ARE) pathway in protecting bovine mammary epithelial cells (BMEC) against H2O2 induced oxidative stress injury. An NFE2L2 small interfering RNA (siRNA) interference or a pCMV6-XL5-NFE2L2 plasmid fragment was transfected to independently downregulate or upregulate expression of NFE2L2. Isolated BMEC in triplicate were exposed to H2O2 (600 MUM) for 6 h to induce oxidative stress before transient transfection with scrambled siRNA, NFE2L2-siRNA, pCMV6-XL5, and pCMV6-XL5-NFE2L2. Cell proliferation, apoptosis and necrosis rates, antioxidant enzyme activities, reactive oxygen species (ROS) and malondialdehyde (MDA) production, protein and mRNA expression of NFE2L2 and downstream target genes, and fluorescence activity of ARE were measured. The results revealed that compared with the control, BMEC transfected with NFE2L2-siRNA3 had proliferation rates that were 9 or 65% lower without or with H2O2, respectively. These cells also had apoptosis and necrosis rates that were 27 and 3.5 times greater with H2O2 compared with the control group, respectively. In contrast, transfected pCMV6-XL5-NFE2L2 had proliferation rates that were 64.3% greater or 17% lower without or with H2O2 compared with the control group, respectively. Apoptosis rates were 1.8 times lower with H2O2 compared with the control. In addition, compared with the control, production of ROS and MDA and activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and glutathione S-transferase (GST) increased markedly in cells transfected with pCMV6-XL5-NFE2L2 and without H2O2. However, compared with the control, production of ROS and MDA and activity of CAT and GSH-Px increased markedly, whereas activities of SOD and GST decreased in cells transfected with pCMV6-XL5-NFE2L2 and incubated with H2O2. Compared with the control, cells transfected with NFE2L2-siRNA3 with or without H2O2 had lower production of ROS and MDA and activity of SOD, CAT, GSH-Px, and GST. Cells transfected with pCMV6-XL5-NFE2L2 with or without H2O2 had markedly higher protein and mRNA expression of NFE2L2, heme oxygenase-1 (HMOX-1), NADH quinone oxidoreductase 1, glutamate cysteine ligase catalytic subunit, and glutamyl cystine ligase modulatory subunit compared with the control incubations. Cells transfected with NFE2L2-siRNA3 without or with H2O2 had markedly lower protein and mRNA expression of NFE2L2, HMOX-1, NADH quinone oxidoreductase 1, glutamyl cystine ligase modulatory subunit, and glutamate-cysteine ligase catalytic subunit compared with the control incubations. In addition, expression of HMOX-1 was 5.3-fold greater with H2O2 compared with the control. Overall, results indicate that NFE2L2 plays an important role in the NFE2L2-ARE pathway via the control of HMOX-1. The relevant mechanisms in vivo merit further study. PMID- 29573799 TI - Metabotypes with elevated protein and lipid catabolism and inflammation precede clinical mastitis in prepartal transition dairy cows. AB - Clinical mastitis (CM), the most prevalent and costly disease in dairy cows, is diagnosed most commonly shortly after calving. Current indicators do not satisfactorily predict CM. This study aimed to develop a robust and comprehensive mass spectrometry-based metabolomic and lipidomic workflow using untargeted ultra performance liquid chromatography high-resolution mass spectrometry for predictive biomarker detection. Using a nested case-control design, we measured weekly during the prepartal transition period differences in serum metabolites, lipids, inflammation markers, and minerals between clinically healthy Holstein dairy cows diagnosed with mastitis postcalving (CMP; n = 8; CM diagnosis d 1 = 3 cows, d 2 = 2 cows, d 4 = 1 cow; d 25 = 1 cow, and d 43 = 1 cow that had subclinical mastitis since d 3) or not (control; n = 9). The largest fold differences between CMP and control cows during the prepartal transition period were observed for 3'-sialyllactose in serum. Seven metabolites (N methylethanolamine phosphate, choline, phosphorylcholine, free carnitine, trimethyl lysine, tyrosine, and proline) and 3 metabolite groups (carnitines, AA metabolites, and water-soluble phospholipid metabolites) could correctly classify cows for their future CM status at both 21 and 14 d before calving. Biochemical analysis using lipid and metabolite-specific commercial diagnostic kits supported our mass spectrometry-based omics results and additionally showed elevated inflammatory markers (serum amyloid A and visfatin) in CMP cows. In conclusion, metabolic phenotypes (i.e., metabotype) with elevated protein and lipid metabolism and inflammation may precede CM in prepartal transition dairy cows. The discovered serum metabolites and lipids may assist in predictive diagnostics, prevention strategies, and early treatment intervention against CM, and thereby improve cow health and welfare. PMID- 29573800 TI - Short communication: The effect of novel antiseptic compounds on umbilical cord healing and incidence of infection in dairy calves. AB - The goal of dipping the umbilical cord after birth in calves is to promote healing of the umbilical stump, prevent infection, and encourage the umbilical tissue to detach from the body. Treatment applied to the umbilical area is an important management step for preventing morbidity and mortality in calves. The objective of this study was to compare the effect of 4 umbilical dips on the healing rate, incidence of infection, and age at umbilical cord detachment using newborn Holstein heifer calves (n = 73). Calves were alternately assigned by birth order to 4 treatment groups: 7% iodine, a dry dip formulated using an antibacterial peptide (nisin) mixed with talc (3.105 g of nisin per 100 g of talcum powder on a weight per weight basis), liquid nisin (64 ug/mL), and 4% chlorhexidine mixed with alcohol in a 50:50 solution. Umbilical cords were dipped 30 min after birth. Before initial dipping, umbilical cord diameter (as an indicator of the rate of cord drying and healing rate) was determined using a digital caliper. The caliper measurements were repeated at 24 +/- 1, 48 +/- 1, and 72 +/- 1 h (+/-standard deviation) of age and were continued daily until the umbilical cord healed and detached from the animal's body. Diagnosed umbilical infections were documented by veterinary staff based on a combination of clinical symptoms (redness, swelling, purulent discharge, painful response (flinch or kicking) to palpation of the umbilical stump) in addition to a lack of appetite and fever. Data were analyzed using MIXED model procedures with fixed effect of umbilical treatment. No treatment differences were noted between dips on the umbilical cord drying rate or days for umbilical cord to detach. Treatment effects were observed on incidence of umbilical infection (incidence of infection for calves across all treatments was 9.0%). PMID- 29573801 TI - Elimination of experimentally induced bovine intramammary infection assessed by multiplex real-time PCR and bacterial culture. AB - Diagnosis of bovine intramammary infection (IMI) has traditionally been based on bacterial culture, but currently IMI can also be detected with DNA based methods, such as multiplex real-time PCR. The aim of this study was to describe the elimination of bacteria in experimentally induced IMI on the quarter level, using conventional bacterial culture (BC) and multiplex real-time PCR. Two coagulase negative staphylococcal species, Staphylococcus epidermidis and Staphylococcus simulans, were experimentally inoculated into 14 healthy quarters of 8 dairy cows during 4 consecutive study periods. Intramammary infections were followed with 20 milk samplings per each quarter. Milk somatic cell count was monitored to evaluate the inflammation process in the quarters. Four quarters cured spontaneously during the study period according to the culture. The PCR detected staphylococcal DNA from these quarters for several days after they were defined as cured in BC. Agreement between BC and PCR results varied from substantial to almost perfect agreement for the first 36 h postchallenge, decreasing to moderate levels toward the end of the sampling period. Based on this study, we recommend collecting possible follow-up samples to assess the bacteriological cure from IMI not until 2 to 3 wk after the onset of mastitis or after the quarter milk somatic cell count has normalized when PCR is used. PMID- 29573802 TI - Milk nutrition and childhood epilepsy: An ex vivo study on cytokines and oxidative stress in response to milk protein fractions. AB - We present a pilot study on the effects of milk protein fractions [alphaS1-casein (CN), alphaS2-CN, kappa-CN, beta-CN, and a mix of alpha-lactalbumin (alpha-LA) and beta-lactoglobulin (beta-LG)] from different animal species (bovine, ovine, and caprine) on pro- and anti-inflammatory cytokines and oxidative status in cultured peripheral blood mononuclear cells from children with generalized epilepsy. Peripheral blood mononuclear cells (PBMC) were obtained by density gradient from blood of 10 children with generalized epilepsy (5 males; mean age 33.6 +/- 5.4 mo) and 10 controls (5 males; mean age 35.6 +/- 6.8 mo). Children with epilepsy were grouped according to cytokine levels as follows: children with epilepsy having low levels of cytokines not different from those of control children (LL-EC); children with epilepsy having cytokine levels at least 5-fold higher (medium levels) than those of control children (ML-EC); and children with epilepsy having cytokine levels at least 10-fold higher (high levels) than those of control children (HL-EC). The production of tumor necrosis factor-alpha (TNF alpha), IL-10, IL-6, and IL-1beta was studied in cultured PBMC incubated with alphaS1-CN, alphaS2-CN, kappa-CN, beta-CN, and a mix of alpha-LA and beta-LG from bovine, caprine, and ovine milks. The levels of reactive oxygen and nitrogen species (ROS/RNS) and catalase activity were assessed in cultured supernatant. In the HL-EC group, beta-CN from small ruminant species (ovine and caprine) induced the highest levels of TNF-alpha, whereas PBMC incubated with alphaS2-CN from ovine milk and the mix of beta-LG and alpha-LA from all tested milk species had the lowest levels of TNF-alpha. Within the HL-EC group, production of IL-1beta was higher for bovine and ovine alphaS2-CN fractions and lower for caprine and ovine beta-CN and kappa-CN. In the HL-EC group, IL-6 was higher in cultured PBMC incubated with alphaS2-CN from bovine and ovine milk than from caprine milk. The cytokine IL-10 did not differ among milking species. The highest levels of ROS/RNS were found after incubation of PBMC with the beta-CN fraction in bovine milk. Catalase activity was higher in PBMC cultured with beta-CN isolated from bovine and caprine milk and with alphaS1-CN from ovine milk. PMID- 29573803 TI - Comparison of effects of routine topical treatments in the milking parlor on digital dermatitis lesions. AB - Digital dermatitis (DD), an infectious bacterial disease affecting the feet of dairy cattle, can cause lameness and decrease milk production, fertility, and animal welfare. Current DD treatment typically involves routine hoof trimming and topical antibiotics. Several nonantibiotic commercial topical products are used for controlling DD lesions; however, there is limited or no evidence regarding their effectiveness. The objectives of this study were to evaluate 2 commercially available topical applications on their ability to (1) clinically cure active DD lesions to nonactive lesions and (2) prevent recurrence of active DD lesions. Ten farms were visited weekly. In the milking parlor, the hind feet of lactating cattle were cleaned and scored (M-stage scoring system). Cattle with DD lesions at the first visit were randomly allocated to 1 of 4 treatment groups: positive control (tetracycline solution), HealMax (AgroChem Inc., Saratoga Springs, NY), HoofSol (Diamond Hoof Care Ltd., Intracare BV, Veghel, the Netherlands), and a negative control (saline). All products were applied to lesions using a spray bottle. Tetracycline, HealMax, and HoofSol had a higher probability of clinical cure for active lesions compared with saline 1 wk after the first treatment (wk 1), with 69, 52, and 79% clinical cure of active lesions, respectively, compared with 34% with saline. At wk 7, the probability of clinical cure for active lesions was 10, 33, 31, and 45% of lesions treated weekly with saline, tetracycline, HealMax, and HoofSol, respectively (no difference among treatments). The substantial clinical cure with saline highlighted the potential importance of cleaning feet. In wk 1, treatment with saline, tetracycline, HealMax, and HoofSol resulted in a probability of recurrence of active DD lesions of 9, 11, 11, and 8%, respectively, with no product being superior to saline. After 7 wk, the probability of recurrence of active lesions was 5, 7, 6, and 6% for saline, tetracycline, HealMax, and HoofSol respectively, with no difference among groups in wk 7. These results provide alternatives to antibiotics for treatment of DD lesions and highlight the potential importance of cleaning feet in the milking parlor. PMID- 29573804 TI - Effects of homolactic bacterial inoculant on the performance of lactating dairy cows. AB - The objective of this experiment was to determine the effect of applying a homofermentative bacterial inoculant to corn silage on the performance of dairy cows. After harvesting, corn forage was treated with nothing (CON) or with an inoculant containing a mixture of Lactococcus lactis, Lactobacillus plantarum, and Enterococcus faecium at 1.5 * 105 cfu/g of fresh forage (MC; SiloSolve MC, Chr. Hansen A/S, Horsholm, Denmark). After 186 d of storage in Ag-Bags (A Miller St. Nazianz Inc., St. Nazianz, WI), silages were fed as part of a total mixed ration containing 55% concentrates, 10% alfalfa hay, and 35% CON or MC corn silage. Sixty early-lactation Holstein dairy cows (30 multiparous and 30 primiparous) housed in a freestall barn with Calan gates (American Calan Inc., Northwood, NH) were assigned to the dietary treatments from 20 to 100 d in milk. Silage inoculated with MC had a more homofermentative pattern evidenced by greater lactic acid concentration (3.83 vs. 4.48% of DM) and lower concentrations of acetic (2.34 vs. 1.68% of DM) and propionic (0.37 vs. 0.10% of DM) acids and ammonia (9.11 vs. 7.82% of N) for CON and MC, respectively. Dry matter intake (23.1 vs. 23.2 kg/d) did not differ among treatments, but the MC silage had greater apparent digestibility of DM (68.8 vs. 70.8%), which led to greater yields of milk (37.7 vs. 38.5 kg/d), fat-corrected milk (37.6 vs. 38.4 kg/d), milk fat (1.30 vs. 1.33 kg/d), and lactose (1.83 vs. 1.92 kg/d) for CON and MC cows, respectively. Milk from cows fed MC silage had higher lactose (4.86 vs. 4.93%), lower protein (2.93 vs. 2.83%), and similar contents of fat (3.47 vs. 3.44%) compared with CON cows. Feed efficiency (fat-corrected milk/dry matter intake) was not affected by treatment (1.69 vs. 1.72 for CON and MC, respectively). Inoculation of corn silage with the homofermentative inoculant increased digestibility of the total mixed ration and increased milk yield by lactating dairy cows. PMID- 29573805 TI - Hunter versus CIE color measurement systems for analysis of milk-based beverages. AB - The objective of our work was to determine the differences in sensitivity of Hunter and International Commission on Illumination (CIE) methods at 2 different viewer angles (2 and 10 degrees ) for measurement of whiteness, red/green, and blue/yellow color of milk-based beverages over a range of composition. Sixty combinations of milk-based beverages were formulated (2 replicates) with a range of fat level from 0.2 to 2%, true protein level from 3 to 5%, and casein as a percent of true protein from 5 to 80% to provide a wide range of milk-based beverage color. In addition, commercial skim, 1 and 2% fat high-temperature, short-time pasteurized fluid milks were analyzed. All beverage formulations were HTST pasteurized and cooled to 4 degrees C before analysis. Color measurement viewer angle (2 vs. 10 degrees ) had very little effect on objective color measures of milk-based beverages with a wide range of composition for either the Hunter or CIE color measurement system. Temperature (4, 20, and 50 degrees C) of color measurement had a large effect on the results of color measurement in both the Hunter and CIE measurement systems. The effect of milk beverage temperature on color measurement results was the largest for skim milk and the least for 2% fat milk. This highlights the need for proper control of beverage serving temperature for sensory panel analysis of milk-based beverages with very low fat content and for control of milk temperature when doing objective color analysis for quality control in manufacture of milk-based beverages. The Hunter system of color measurement was more sensitive to differences in whiteness among milk-based beverages than the CIE system, whereas the CIE system was much more sensitive to differences in yellowness among milk-based beverages. There was little difference between the Hunter and CIE system in sensitivity to green/red color of milk-based beverages. In defining milk-based beverage product specifications for objective color measures for dairy product manufacturers, the viewer angle, color measurement system (CIE vs. Hunter), and sample measurement temperature should be specified along with type of illuminant.

AB - The objective of this study was to compare genetic trends from single-step genomic BLUP (ssGBLUP) and traditional BLUP models for milk production traits of US Holsteins. Phenotypes were 305-d milk, fat, and protein yields from 21,527,040 cows recorded between January 1990 and August 2015. The pedigree file included 29,651,623 animals and was limited to 3 generations back from recorded or genotyped animals. Genotypes for 764,029 animals were used, and analyses were by a 3-trait repeatability model as used in the US official genetic evaluation. Unknown-parent groups were incorporated into the inverse of a relationship matrix (H-1 in ssGBLUP and A-1 in BLUP) with the QP transformation. For ssGBLUP, 18,359 genotyped animals were randomly chosen as core animals to calculate the inverse of the genomic relationship matrix with the APY algorithm. Computations took 6.5 h and 1.4 GB of memory for BLUP, and 13 h and 115 GB of memory for ssGBLUP. For genotyped sires with at least 10 daughters, the average genetic levels for predicted transmitting ability (PTA) and genomic PTA were similar up to 2008, with a higher level for ssGBLUP later (approximately by 36 kg for milk, 2.1 kg for fat, and 1.1 kg for protein for bulls born in 2010). For genotyped cows, the average genetic levels were similar up to 2006, with a higher level for ssGBLUP (approximately by 91 kg for milk, 3.6 kg for fat, and 2.7 kg for protein for cows born in 2012). For all cows, the average levels were slightly higher for ssGBLUP, with much smaller differences than for genotyped cows. Trends for BLUP indicate bias due to genomic preselection for genotyped sires and cows. For official evaluations released in December 2016, traditional PTA had the same trend as multiple-step genomic PTA for both genotyped bulls and cows except for the youngest bulls, who had traditional PTA slightly lower than genomic PTA. For genotyped bulls born in recent years, genetic gain for official traditional and genomic evaluations was similar in contrast to ssGBLUP and BLUP differences. Official PTA for cows were adjusted so that the Mendelian sampling variance was comparable with that for bulls, and those adjustments likely removed bias due to genomic preselection from traditional PTA, especially for genotyped cows. The ssGBLUP method seems to account partially for that bias and is computationally suitable for national evaluations. PMID- 29573807 TI - Bifidobacterium bifidum YIT 10347 fermented milk exerts beneficial effects on gastrointestinal discomfort and symptoms in healthy adults: A double-blind, randomized, placebo-controlled study. AB - In a preliminary open-label trial by our group, Bifidobacterium bifidum YIT 10347 (YIT10347) relieved gastric symptoms in patients with functional gastrointestinal disorders. Hence, in this study, we investigated the effects of YIT10347 on gastrointestinal symptoms in healthy adults. In this prospective double-blind, randomized, placebo-controlled trial (UMIN000024654), 100 healthy Japanese adults were randomly assigned to a YIT10347 group or placebo group and consumed 100 mL of YIT10347-fermented milk or placebo fermented milk, respectively, every day for 4 wk. Gastrointestinal symptoms were evaluated by using the modified Frequency Scale for Symptoms of Gastroesophageal Reflux Disease (m-FSSG) and Gastrointestinal Symptom Rating Scale (GSRS) as primary endpoints. Mental symptoms, quality of life, salivary stress markers, and gastric emptying were evaluated as secondary endpoints. Effectiveness and safety were analyzed in a per protocol set (YIT10347 group, n = 39; placebo group, n = 40) and full analysis set (YIT10347 group, n = 50; placebo group, n = 50), respectively. In the m-FSSG evaluation, the YIT10347 group had a significantly higher relief rate of postprandial discomfort and greater changes in postprandial epigastric pain score from baseline than the placebo group. In the GSRS evaluation, the YIT10347 group had significantly higher relief rates of overall gastrointestinal symptoms, upper gastrointestinal symptoms, flatus, and diarrhea than the placebo group. We detected no significant differences in scores or relief rates of mental symptoms and quality of life, a salivary stress marker, or gastric emptying between the 2 groups. No severe adverse events associated with test beverage consumption were observed in either group. These findings suggest that daily consumption of YIT10347-fermented milk exerts beneficial effects on gastrointestinal discomfort and symptoms such as postprandial discomfort and epigastric pain in healthy adults. PMID- 29573808 TI - Effect of temperature and pH on the properties of skim milk gels made from a tamarillo (Cyphomandra betacea) coagulant and rennet. AB - Reconstituted skim milk was gelled with a crude protease extract from tamarillo [Cyphomandra betacea or Solanum betacea (syn.)] fruit and compared with gels prepared with calf rennet. The effects of temperature and pH on the gelation of skim milk were investigated by small deformation oscillatory rheology. The tamarillo extract-induced gels had a faster rate of increase in the elastic modulus (G') at the early stage of gelation than rennet-induced milk gels. This was probably due to the broader proteolytic activity of tamarillo protease extracts as shown by sodium dodecyl sulfate-PAGE analysis. Confocal microscopy also showed that the milk gels resulting from the addition of tamarillo extracts had larger voids than rennet-induced milk gels. The proteolytic activity of tamarillo extracts was found to be optimal at pH 11. For both rennet and tamarillo extracts, the aggregation time was similar between pH 6.7 and 6.5, but the aggregation time of rennet-induced milk gels was lower than that of milk gels obtained by the addition of tamarillo extracts at pH lower than 6.5. An increase in temperature was found to have a significant effect on aggregation time, particularly at 20 degrees C, where rennet did not coagulate milk in 3 h but the tamarillo extracts coagulated milk within 2 h. The results of this study suggest that extracts from tamarillo fruit could be used for milk gelation, particularly under lower temperature or high pH conditions. PMID- 29573809 TI - [Development of a standardized guide for optimizing drug adherence information to be dispensed during a pharmaceutical counseling with a multiple myeloma patient: Initial validation]. AB - The safety of the community treatment with oral anticancer therapies is a strong theme of the cancer plan 2014-2019. The objective of this study was to develop a Pharmaceutical Counseling Guide to improve medication adherence in patients treated for multiple myeloma with oral anticancer therapies. A multidisciplinary professional working group selected a list of relevant medication adherence related items that served as the framework for the design of the pharmaceutical counseling support materials in patient-accessible language. The readability, understanding and memorization of the information were validated in ten patients treated for myeloma. Twelve items were selected for treatment information (5 items), treatment planning (5 items), and adverse drug effects (2 items). A pharmacist guide, a patient guide, a medication schedule, and three self questionnaires to evaluate medication knowledge and understanding of patients were developed. The patient test resulted in changes in these documents. This study carried out the initial validation of documents to standardize the pharmaceutical counseling for patients treated for myeloma so that it can be reproduced from one patient to another regardless of the pharmacist, by standardizing the information issued. This study needs to be completed by a final validation in myeloma patients, free from oral anticancer therapies. PMID- 29573810 TI - Meta-Analysis of Trials on Prophylactic Use of Levosimendan in Patients Undergoing Cardiac Surgery. AB - BACKGROUND: The role of prophylactic levosimendan in patients undergoing cardiac surgery is controversial. METHODS: We performed a computerized search of Medline, Embase, and Cochrane databases through September 2017 for randomized trials evaluating the prophylactic use of levosimendan in patients undergoing cardiac surgery (ie, patients without low cardiac output syndrome). The main study outcome was mortality at 30 days. RESULTS: The final analysis included 16 randomized trials with total of 2,273 patients. There was no statistically significant difference in mortality at 30 days between levosimendan and control groups (relative risk 0.68, 95% confidence interval [CI]: 0.45 to 1.03). Subgroup analysis showed no statistically significant difference in mortality at 30 days for patients with reduced left ventricular ejection fraction compared with patients having preserved left ventricular ejection fraction (p for interaction = 0.12). Further analysis suggested that levosimendan might be associated with improved mortality at 30 days when compared with active-control but not when compared with placebo (p for interaction = 0.01). The levosimendan group had a significant reduction in acute kidney injury (relative risk 0.59, 95% CI: 0.38 to 0.92), intensive care unit stay (standardized mean difference = -0.21, 95% CI: 0.29 to -0.13), and ventilation time (standardized mean difference = -0.43, 95% CI: -0.61 to -0.25), whereas it had higher rates of atrial fibrillation (relative risk 1.11, 95% CI: 1.00 to 1.24). No statistically significant differences were observed between groups in mortality beyond 30 days, postoperative dialysis, or myocardial infarction. CONCLUSIONS: Prophylactic use of levosimendan does not appear to reduce the mortality at 30 days or beyond 30 days in patients undergoing cardiac surgery. This lack of benefit was noted irrespective of the LVEF. PMID- 29573811 TI - The discovery of deep-water seagrass meadows in a pristine Indian Ocean wilderness revealed by tracking green turtles. AB - Our understanding of global seagrass ecosystems comes largely from regions characterized by human impacts with limited data from habitats defined as notionally pristine. Seagrass assessments also largely focus on shallow-water coastal habitats with comparatively few studies on offshore deep-water seagrasses. We satellite tracked green turtles (Chelonia mydas), which are known to forage on seagrasses, to a remote, pristine deep-water environment in the Western Indian Ocean, the Great Chagos Bank, which lies in the heart of one of the world's largest marine protected areas (MPAs). Subsequently we used in-situ SCUBA and baited video surveys to survey the day-time sites occupied by turtles and discovered extensive monospecific seagrass meadows of Thalassodendron ciliatum. At three sites that extended over 128 km, mean seagrass cover was 74% (mean range 67-88% across the 3 sites at depths to 29 m. The mean species richness of fish in seagrass meadows was 11 species per site (mean range 8-14 across the 3 sites). High fish abundance (e.g. Siganus sutor: mean MaxN.site-1 = 38.0, SD = 53.7, n = 5) and large predatory shark (Carcharhinus amblyrhynchos) (mean MaxN.site-1 = 1.5, SD = 0.4, n = 5) were recorded at all sites. Such observations of seagrass meadows with large top predators, are limited in the literature. Given that the Great Chagos Bank extends over approximately 12,500 km2 and many other large deep submerged banks exist across the world's oceans, our results suggest that deep-water seagrass may be far more abundant than previously suspected.

PMID- 29573813 TI - Appetite-associated responses to central neuropeptide Y injection in quail. AB - The appetite-associated effects of neuropeptide Y (NPY) have been extensively studied in mammalian models. Less knowledge exists for other vertebrate species including birds. The aim of this study was to determine the effects of central injection of NPY on feeding behavior and hypothalamic physiology in 7 day-old Japanese quail (Coturnix japonica). During the light cycle, intracerebroventricular injection of 1.9 pmol, 0.5, and 1.0 nmol doses of NPY did not affect food intake, 0.031 to 0.13 nmol increased food intake, and 2.0 nmol NPY decreased food intake, in comparison to vehicle injection. Multiple doses of NPY stimulated water intake, but when food was not available, water intake was not affected. When injected during the dark cycle, NPY did not influence food intake. NPY-injected chicks had more c-Fos immunoreactive cells in the arcuate nucleus of the hypothalamus (ARC) and greater hypothalamic agouti-related peptide and neuropeptide Y receptors 1 and 2 (NPYR1 and NPYR2, respectively) mRNA than vehicle-injected chicks. Within the ventromedial hypothalamus, NPY-treated chicks expressed less NPYR1 mRNA, within the dorsomedial hypothalamus less NPY mRNA, and in the ARC greater NPYR2 mRNA than vehicle-injected chicks. Lastly, quail injected with NPY increased feeding pecks, escape attempts, and time spent preening, while locomotion, the number of steps, and time spent perching decreased compared to chicks injected with the vehicle. Results demonstrate that NPY stimulates food intake in quail, consistent with mammals and other avian species, but with some unique responses at the molecular level that are not documented in other species. PMID- 29573814 TI - Pupillary Responses to Full-Field Chromatic Stimuli Are Reduced in Patients with Early-Stage Primary Open-Angle Glaucoma. AB - PURPOSE: To evaluate the ability of chromatic pupillometry to reveal abnormal pupillary responses to light in patients with early-stage primary open-angle glaucoma (POAG) and to test whether the degree of pupillometric impairment correlates with structural hallmarks of optic nerve damage in the disease. DESIGN: Cross-sectional study. PARTICIPANTS: Forty-six patients with early-stage POAG (63.4+/-8.3 years, 63% male, 87% ethnic-Chinese) and 90 age-matched healthy controls (61.4+/-8.6 years, 34% male, 89% ethnic-Chinese). Patients with POAG had a visual field mean deviation (VFMD) of -6 decibels or better on automated perimetry. METHODS: Each participant underwent a monocular 2-minute exposure to blue light (462 nm) followed by another 2-minute exposure to red light (638 nm) using a modified Ganzfeld dome equipped with a light-emitting diode lighting system. The light stimuli intensity was increased logarithmically to evaluate the combined extrinsic and intrinsic response of intrinsically photosensitive retinal ganglion cells (ipRGCs). Light-induced changes in horizontal pupil diameter were assessed monocularly using infrared pupillography. MAIN OUTCOME MEASURES: Baseline-adjusted, light-induced pupillary constriction amplitudes were calculated, and individual irradiance-response curves were constructed for each stimulus. Pupillary constriction amplitudes were compared between groups and across light intensities using a linear mixed model analysis. The linear relationship between pupillometric parameters and different structural and functional features of glaucoma was assessed using Pearson's correlation analysis. RESULTS: Light-induced pupillary constriction was reduced in patients with early-stage POAG compared with controls at moderate to high irradiances (>=11 Log photons/cm2/s) of blue (P = 0.003) and red (P < 0.001) light. Maximal pupillary constriction amplitude was correlated with retinal nerve fiber layer thickness (RNFL) thickness (blue: r = 0.51, P < 0.001; red: r = 0.45, P = 0.002) in patients with POAG but not in controls. Conversely, pupillometric parameters were not correlated with visual field scores in patients with early-stage POAG. CONCLUSIONS: Patients with early-stage POAG exhibit reduced pupillary responses to moderate and high irradiances of blue and red lights. This wavelength independent functional alteration correlates with structural thinning of the RNFL and could be the consequence of dysfunction or loss of melanopsin expressing ipRGCs in the early stages of the disease. PMID- 29573815 TI - Safety of Lumbar Puncture Performed on Dual Antiplatelet Therapy. AB - Practice guidelines generally recommend delaying lumbar puncture (LP) in patients on dual antiplatelet therapy, with these recommendations often citing an increased risk of hemorrhagic complications, specifically the development of epidural hematomas. However, no data exist about the risks of performing an LP in the setting of dual antiplatelet therapy and conclusions are often based on data from spinal anesthesia literature. We reviewed the medical records of 100 patients who underwent LP while taking dual antiplatelet therapy. We recorded the number of traumatic and bloody cerebrospinal fluid results as well as the presence of any complications occurring within 3 months of the procedure. Complications requiring imaging or hospitalization were considered serious. The most common complication was back pain, which was reported by 2 patients, only 1 of which was ultimately found to be attributable to the procedure. No serious complications occurred. Cerebrospinal fluid analysis was consistent with a traumatic LP, defined as having at least 100 red blood cells per microliter, in 8% of cases. Bloody LP, defined as having 1000 red blood cells per microliter, occurred in 4% of cases. The percentage of traumatic or bloody LPs was within the range reported previously for LPs performed in any setting. Although this is a small study and additional review is necessary, performing LPs in the setting of dual antiplatelet therapy may not pose an increased risk of serious complications. PMID- 29573816 TI - Diabetes mellitus prevalence in patients with takotsubo syndrome: the case of the brain-heart disconnect. AB - BACKGROUND: Hyperactive autonomic nervous system (ANS) is among the postulated pathophysiologic mechanisms of takotsubo syndrome (TTS). Diabetes mellitus (DM) with its associated ANS peripheral neuropathy could exert a "protective" influence for the emergence of TTS. METHODS: A patient-based meta-analysis of the data obtained from all patients presented individually was carried out, focusing on age, gender, and history of hypertension (HTN) and DM. RESULTS: The prevalences of HTN and DM for all 2,342 patients, aged 61.1 +/- 17.3, 85.1% female, were 37.4% and 9.5%, for patients >= 60 years old were 45.8% and 11.7%, and for patients >=65 years old were 48.2% and 12.3%, correspondingly. The prevalence of DM in patients with TTS is less than half of the world's and USA's elderly populations. CONCLUSIONS: Prevalence of DM in patients with TTS is lower than in the general population, suggesting that DM, may have a "protective" effect for the emergence of TTS.

PMID- 29573818 TI - Understanding Alzheimer Disease at the Interface between Genetics and Transcriptomics. AB - Over 25 genes are known to affect the risk of developing Alzheimer disease (AD), the most common neurodegenerative dementia. However, mechanistic insights and improved disease management remains limited, due to difficulties in determining the functional consequences of genetic associations. Transcriptomics is increasingly being used to corroborate or enhance interpretation of genetic discoveries. These approaches, which include second and third generation sequencing, single-cell sequencing, and bioinformatics, reveal allele-specific events connecting AD risk genes to expression profiles, and provide converging evidence of pathophysiological pathways underlying AD. Simultaneously, they highlight brain region- and cell-type-specific expression patterns, and alternative splicing events that affect the straightforward relation between a genetic variant and AD, re-emphasizing the need for an integrated approach of genetics and transcriptomics in understanding AD.

PMID- 29573820 TI - Potent anti-viral vaccine adjuvant based on pH-degradable nanogels with covalently linked small molecule imidazoquinoline TLR7/8 agonist. AB - Improving the immunogenicity of subunit vaccines, in particular skewing of the immune response towards Th1 type immunity, is crucial for the development of effective vaccines against intracellular infections and for the development of anti-cancer vaccines. Small molecule TLR7/8 agonist hold high potential for this purpose, but suffer from an undesirable pharmacokinetic profile, resulting in systemic inflammatory responses. An effective solution to this problem is covalent ligation to a larger carrier. Here, a degradable nanogel carrier containing a covalently linked imidazoquinoline (IMDQ) TLR7/8 agonist is explored as adjuvant for vaccination against the respiratory syncytial virus (RSV). In vitro and in vivo experiments in mice provide a solid rational base for preferring nanogels over soluble polymers as IMDQ carrier in terms of cellular uptake and lymph node accumulation.

AB - Advances in the understanding of the complexities of the Wnt signaling pathway during development and tissue homeostasis have made the Wnt pathway one of the prime candidates for translational applications during tissue regeneration. Wnts are key components of the stem cell niche and are short range signaling molecules responsible for cellular decisions such as proliferation and differentiation. Systemic treatment using biologics targeting the Wnt signaling pathway have shown promising early results and will likely enter the clinical arena in the near future. This comprehensive review summarizes the intricacies how Wnts function in the context of the bone regeneration.

PMID- 29573823 TI - Determination of the proton RBE in the rat spinal cord: Is there an increase towards the end of the spread-out Bragg peak? AB - BACKGROUND AND PURPOSE: To determine the relative biological effectiveness (RBE) of protons in the rat spinal cord as a function of linear energy transfer (LET) and dose. MATERIALS AND METHODS: The rat cervical spinal cord was irradiated with single or two equal fractions (split doses) of protons at four positions (LET 1.4 5.5 keV/um) along a 6 cm spread-out Bragg peak (SOBP). From dose-response analysis, TD50- (dose at 50% effect probability) and RBE-values were derived using the endpoint of radiation-induced myelopathy. RESULTS: Along the SOBP, the TD50-values decreased from 21.7 +/- 0.3 Gy to 19.5 +/- 0.5 Gy for single and from 32.3 +/- 0.3 Gy to 27.9 +/- 0.5 Gy for split doses. The corresponding RBE-values increased from 1.13 +/- 0.04 to 1.26 +/- 0.05 (single doses) and from 1.06 +/- 0.02 to 1.23 +/- 0.03 (split doses). CONCLUSIONS: For the relative high fractional doses, the experimental RBE at the distal edge of the proton SOBP is moderately increased. The conventionally applied RBE of 1.1 appears to be valid for the mid-SOBP region, but the higher values occurring more distally could be of clinical significance, especially if critical structures are located in this area. Further in vivo studies at lower fractional doses are urgently required.

PMID- 29573825 TI - Inorganic fouling mitigation by salinity cycling in batch reverse osmosis. AB - Enhanced fouling resistance has been observed in recent variants of reverse osmosis (RO) desalination which use time-varying batch or semi-batch processes, such as closed-circuit RO (CCRO) and pulse flow RO (PFRO). However, the mechanisms of batch processes' fouling resistance are not well-understood, and models have not been developed for prediction of their fouling performance. Here, a framework for predicting reverse osmosis fouling is developed by comparing the fluid residence time in batch and continuous (conventional) reverse osmosis systems to the nucleation induction times for crystallization of sparingly soluble salts. This study considers the inorganic foulants calcium sulfate (gypsum), calcium carbonate (calcite), and silica, and the work predicts maximum recovery ratios for the treatment of typical water sources using batch reverse osmosis (BRO) and continuous reverse osmosis. The prediction method is validated through comparisons to the measured time delay for CaSO4 membrane scaling in a bench-scale, recirculating reverse osmosis unit. The maximum recovery ratio for each salt solution (CaCO3, CaSO4) is individually predicted as a function of inlet salinity, as shown in contour plots. Next, the maximum recovery ratios of batch and conventional RO are compared across several water sources, including seawater, brackish groundwater, and RO brine. Batch RO's shorter residence times, associated with cycling from low to high salinity during each batch, enable significantly higher recovery ratios and higher salinity than in continuous RO for all cases examined. Finally, representative brackish RO brine samples were analyzed to determine the maximum possible recovery with batch RO. Overall, the induction time modeling methodology provided here can be used to allow batch RO to operate at high salinity and high recovery, while controlling scaling. The results show that, in addition to its known energy efficiency improvement, batch RO has superior inorganic fouling resistance relative to conventional RO. PMID- 29573826 TI - Development of voluntary private health insurance in Nordic countries - An exploratory study on country-specific contextual factors. AB - The Nordic countries are healthcare systems with tax-based financing and ambitions for universal access to comprehensive services. This implies that distribution of healthcare resources should be based on individual needs, not on the ability to pay. Despite this ideological orientation, significant expansion in voluntary private health insurance (VPHI) contracts has occurred in recent decades. The development and role of VPHIs are different across the Nordic countries. Complementary VPHI plays a significant role in Denmark and in Finland. Supplementary VPHI is prominent in Norway and Sweden. The aim of this paper is to explore drivers behind the developments of the VPHI markets in the Nordic countries. We analyze the developments in terms of the following aspects: the performance of the statutory system (real or perceived), lack of coverage in certain areas of healthcare, governmental interventions or inability to reform the system, policy trends and the general socio-cultural environment, and policy responses to voting behavior or lobbying by certain interest groups. It seems that the early developments in VPHI markets have been an answer to the gaps in the national health systems created by institutional contexts, political decisions, and cultural interpretations on the functioning of the system. However, once the market is created it introduces new dynamics that have less to do with gaps and inflexibilities and more with cultural factors. PMID- 29573827 TI - The experience of being a psychiatric nurse in South Africa: A qualitative systematic review. AB - PURPOSE: The purpose of the study was to summarize the experiences of African psychiatric nurses in their workplace by examining the findings of existing qualitative studies. METHODS: Eleven studies published in English, Portuguese, and Spanish, between 1998 and 2016, which explored psychiatric nurses' experiences in Africa, were included. FINDINGS: After meta-aggregation, five key findings were identified: 1) organization and management, 2) perceptions of professional safety and insecurity, 3) relationship with the patient, 4) emotional experiences and 5) recommendations for improvement. DISCUSSION: The findings in this study highlight the stressful nature of the work climate of the psychiatric nurse in South Africa. More focus on improving working conditions and providing support is necessary to increase the quality of care for psychiatric mental health patients and their nurse providers. PMID- 29573828 TI - Systems biology for nursing in the era of big data and precision health. AB - BACKGROUND: The systems biology framework was previously synthesized with the person-environment-health-nursing metaparadigm. PURPOSE: The purpose of this paper is to present a nursing discipline-specific perspective of the association of systems biology with big data and precision health. METHOD: The fields of systems biology, big data, and precision health are now overviewed, from origins through expansions, with examples of what is being done by nurses in each area of science. DISCUSSION: Technological advances continue to expand omics and other varieties of big data that inform the person's phenotype and health outcomes for precision care. Meanwhile, millions of participants in the United States are being recruited for health-care research initiatives aimed at building the information commons of digital health data. CONCLUSIONS: Implications and opportunities abound via conceptualizing the integration of these fields through the nursing metaparadigm. PMID- 29573829 TI - Comparison of theory and experiment for NAPL dissolution in porous media. AB - Contamination of groundwater resources by an immiscible organic phase commonly called NAPL (Non Aqueous Phase Liquid) represents a major scientific challenge considering the residence time of such a pollutant. This contamination leads to the formation of NAPL blobs trapped in the soil and impact of this residual saturation cannot be ignored for correct predictions of the contaminant fate. In this paper, we present results of micromodel experiments on the dissolution of pure hydrocarbon phase (toluene). They were conducted for two values of the Peclet number. These experiments provide data for comparison and validation of a two-phase non-equilibrium theoretical model developed by Quintard and Whitaker (1994) using the volume averaging method. The model was directly upscaled from the averaged pore-scale mass balance equations. The effective properties of the macroscopic model were calculated over periodic unit cells designed from images of the experimental flow cell. Comparison of experimental and numerical results shows that the transport model predicts correctly - with no fitting parameters - the main mechanisms of NAPL mass transfer. The study highlights the crucial need of having a fair recovery of pore-scale characteristic lengths to predict the mass transfer coefficient with accuracy. PMID- 29573830 TI - Gastric Mucormycosis in a Liver and Kidney Transplant Recipient: Case Report and Concise Review of Literature. AB - Mucormycosis is an uncommonly encountered fungal infection in solid organ transplantation. The infection is severe and often results in a fatal outcome. The most common presentations are rhino-sino-orbital and pulmonary disease. We describe a rare case of gastric mucormycosis in a patient with a combined liver kidney transplant affected by glycogen storage disease type Ia. A 42-year-old female patient presented with gastric pain and melena 26 days after transplantation. Evaluation with upper endoscopy showed two bleeding gastric ulcers. Histological examination of gastric specimens revealed fungal hyphae with evidence of Mucormycetes at subsequent molecular analysis. Immunosuppressive therapy was reduced and antifungal therapy consisting of liposomal amphotericin B and posaconazole was promptly introduced. Gastrointestinal side effects of posaconazole and acute T-cell rejection of renal graft complicated management of the case. A prolonged course of daily injections of amphotericin B together with a slight increase of immunosuppression favored successful treatment of mucormycosis as well as of graft rejection. At 2-year follow-up, the woman was found to have maintained normal renal and liver function. We conclude that judicious personalization of antimicrobial and antirejection therapy should be considered to resolve every life-threatening case of mucormycosis in solid organ transplantation. PMID- 29573831 TI - Morphogenetic movements affect local tissue organisation during embryonic Drosophila morphogenesis. AB - Tissues and organs undergo extensive remodelling to reach their final morphology and physiological activity. The genetic programs underlying tissue formation are well studied, but less is known about how this formation is influenced by extrinsic forces derived from other concomitant morphogenetic events. Here we address this question in Drosophila melanogaster. We analyse tissue organisation in the embryonic epidermis at stage 10 by computational tissue segmentation methods to provide a quantitative description of packing. We find that the epidermis adopts different organisations along the dorso-ventral axis that correlate with differences in cell density. We analyse the contribution of three morphogenetic events that take place right before or concomitant to this period of embryogenesis, neuroblast delamination, asynchronous postblastoderm cell divisions and germ band extension, and we find that they all exert an influence on the packing of the epidermis. We previously described that the apical determinant Crumbs accumulates differentially in the epidermis along the dorso ventral axis. Here we find that this differential accumulation of Crumbs correlates with the differential tissue packing. Perturbation of the three mentioned morphogenetic events also modulate Crumbs differential accumulation, suggesting that Crb could act as a read-out of tissue organisation. We also previously showed that Crb plays a role in regulating cell architecture. Now we find that it is also required for proper packing of the embryonic epidermis. In summary, here we uncover an intimate relationship between morphogenetic events and cell packing within a tissue that is dependent on surrounding cell density. Furthermore we find that this morphogenetically-regulated tissue packing modulates the key cell polarity protein Crumbs, which in turn is required for tissue packing, suggesting that it may participate in the molecular mechanism/s underlying the described tissue organisation. PMID- 29573832 TI - Critical care nurses' knowledge of, adherence to, and barriers toward institution specific ventilator bundle. AB - BACKGROUND: Although evidence-based practices are known to improve the quality of care, making it cost-efficient and improving clinical results, barriers to transferring research into clinical practice have hindered this process. AIMS: To evaluate critical care nurses' knowledge of, adherence to, and barriers toward institution-specific ventilator bundle. MATERIAL AND METHODS: In 2015, we conducted an institution-specific, cross-sectional study in a 26-bed adult mixed medical-surgical intensive care unit (ICU) in Finland using quantitative survey of knowledge and self-reported adherence with qualitative gathering of barrier data. A pre-validated multiple-choice Ventilator Bundle Questionnaire was distributed to all registered nurses who were direct care providers (n = 155). RESULTS: The final response rate was 55.5% (n = 86), and 47.2% (n = 34) of respondents had more than 10 years of ICU experience. The levels of knowledge and self-reported adherence were 71.1% and 65.8% of the total score, respectively. The level of knowledge was higher among respondents who had received in-service education about ventilator bundle compared with respondents who had not received in-service education (27.0 vs 24.0 [P = .012]). Less experienced nurses reported significantly higher adherence than nurses with more ICU experience (29.0 vs 25.0 [P = .034]). The correlation between knowledge and adherence scores was low (rho 0.48 [P <.001]). The most well-known and adhered-to guidelines described patient positioning, daily chlorhexidine-based oral care, and strict hand hygiene. The least-known guidelines and those least adhered to described respiratory equipment, management of sedation and analgesia, and practices prior to and during endotracheal suctioning. The main barriers were related to the nurse respondents (e.g., lack of education [25.9%]), environment (e.g., role ambiguities [36.4%] and inadequate resources [21.1%]), and patients (e.g., patient discomfort [4.8%] and fear of adverse effects [4.6%]). CONCLUSIONS: Self reported adherence did not correlate with knowledge and was not related to work experience. Most of the barriers toward evidence-based guidelines indicated a need for changes that are beyond the control of individual nurses. PMID- 29573833 TI - Erratum.

AB - INTRODUCTION: The treatment of localised prostate cancer seeks to minimise the impact on sexual function and urinary continence. In this respect, therapy with high-intensity focused ultrasound offers important results. We present our experience with this technique in 2 Spanish centres. MATERIAL AND METHODS: We conducted a retrospective review of 75 patients with localised prostate cancer treated with high-intensity focused ultrasound between March 2007 and July 2016. The oncological results and perioperative complications were assessed, as well as the impact on sexual function and continence. RESULTS: A total of 67 patients were analysed. The mean follow-up was 7.2 years. The PSA nadir was 0.2ng/mL (0 3), 24 patients (35.5%) presented biochemical recurrence, and 18 underwent a further biopsy, with 10 cases (55.5%) presenting disease recurrence. The overall biochemical relapse-free survival at 5 and 8 years was 93.2 and 80.5%, respectively. The cancer-specific survival at 5 and 8 years was 96% in both cases. In the postoperative period, 50 patients (74.6%) were continent, 16 (23.9%) reported mild incontinence, and one (1.5%) reported moderate incontinence. The median International Index of Erectile Function-5 before and after the surgery was 17 (5-25) and 16 (2-23) points, respectively. Nine patients reported de novo erectile dysfunction (13.5%). CONCLUSION: High-intensity focused ultrasound appears to be a safe alternative for the treatment of localised prostate cancer, especially for low-risk localised prostate cancer. In our experience, this technique offers advantages in preserving urinary continence, and the medium-term oncological results are encouraging. Given the natural progression of prostate cancer, long-term studies with a larger number of cases are needed to corroborate these results.

AB - BACKGROUND: Monkeypox is a zoonosis caused by an Orthopoxvirus of the Poxviridae family. Human infections are often severe and are a public health problem. PATIENTS AND METHOD: We conducted a monkeypox outbreak investigation of suspected case patients in five villages of the Alindao-Mingala Health District following blood sample confirmation of the virus by the Institut Pasteur in Bangui. We aimed to determine disease characteristics, to describe the context and the risk factors, and to measure the incidence and case fatality. Patients were reported in the villages of Rehou 4, 5, Dalakere 1, Kongbo, and Pavika from August to October 2016. Data was collected on individual records when interviewing patients or parents. RESULTS: A total of 26 patients were identified. The?10 years and 21 30 years age groups were the most affected. The overall attack rate was 5 per 1000 inhabitants and the case fatality was 7.7%. Young age and the absence of smallpox vaccination were associated with severe presentations in 87.5% of cases. CONCLUSION: The annual number of monkeypox outbreaks increases in the Central African Republic with severe presentations and a high case fatality especially in children. Reinforcing the surveillance and characterization of circulating strains will provide information on the need for vaccine production.

AB - Alexander disease (AxD) is a progressive neurodegenerative disease caused by a mutation in the glial fibrillary acid protein (GFAP) gene. A 4-year-old boy presented several times with hemiclonic seizures with eye deviation for a few minutes at 28 days after birth. Electroencephalogram showed independent sharp waves in the right and left temporal area. Magnetic resonance imaging showed high intensity T1-weighted images in the white matter of the frontal lobe and basal ganglia. He showed no head control at 4 years of age, and his weight gain was insufficient. He did not show macrocephaly. At 4 years of age, he died of bacterial pneumonia and septic shock. He was diagnosed with AxD, and direct sequencing revealed a de novo known mutation, c. 239 T > C, p.(F80S), in GFAP. Hela and U2-OS cells transfected with GFAP cDNA with c. 239 T > C showed dot-like cytoplasmic aggregation, similar to R239C, a common mutation found in severe infantile AxD. Aggregation in the cytoplasm caused by a GFAP mutation is a hallmark of AxD. Although there is only one previous report of a patient with an F80S mutation, our data support that F80S can cause the severe, infantile form of AxD. PMID- 29573843 TI - Thoracic Imaging of Non-Small Cell Lung Cancer Treated With Anti-programmed Death Receptor-1 Therapy. AB - PURPOSE: Treatment with anti-programmed death receptor-1 (PD-1) therapeutics can lead to unconventional responses and side effect profiles due to their potentiating effects on the immune system. Here we evaluate the radiologic manifestations of anti-PD-1 therapy in the chest in patients with non-small cell lung cancer (NSCLC) receiving anti-PD-1 therapy. MATERIALS AND METHODS: A retrospective review of real-world clinical practice was conducted of all the patients with NSCLC receiving anti-PD-1 therapy at our institution between 2013 and 2016. All patients without adequate clinical or radiologic follow-up data in the electronic medical records were excluded. Imaging examinations for all patients deemed by their thoracic oncologists to have radiologic pseudoprogression or therapy-associated pneumonitis were reviewed by experienced thoracic radiologists. RESULTS: A total of 166 patients with NSCLC had available clinical and imaging data for retrospective review. Of these patients, 4 (2%) were considered to have radiologic pseudoprogression, 3 of which manifested as increased tumor size and 1 of which manifested with new lesions. A total of 5 patients (3%) were clinically deemed to have pneumonitis attributable to anti-PD 1 therapy, 4 of which had radiologic manifestations on computed tomography. CONCLUSION: Radiologic pseudoprogression and drug-induced pneumonitis are uncommon but important manifestations of anti-PD-1 therapy on thoracic imaging. PMID- 29573844 TI - Expression of genes for enzymes synthesizing lysophosphatidic acid, its receptors and follicle developmental factors derived from the cumulus-oocyte complex is dependent on the ovarian follicle type in cows. AB - Cumulus-oocyte complexes (COCs) release factors potentially involved in follicular growth and development, such as growth and differentiation factor 9 (GDF9), bone-morphogenetic protein 15 (BMP15), follistatin (FST) and cathepsins (CTSs). Moreover, the quality of the oocytes and follicles may be related to both the lipid composition of the follicle cells and follicular fluid. One of the lipids, locally regulating the reproductive functions in ovaries of cattle, is lysophosphatidic acid (LPA). In this study, the expression was investigated of the genes for LPA and other factors in COCs of follicles at different stages of development and regression. The relative abundances of mRNA were determined by real-time PCR for receptors for LPA (LPARs), enzymes synthesizing LPA (autotaxin (AX) and phospholipase A2 (PLA2)), BMP15, GDF9, CTSZ, CTSB and FST in COCs isolated from healthy, transitional and atretic follicles. The expression of genes for the LPARs, AX, PLA2 and the factors involved in follicular development in cattle COCs is follicle-type dependent. Greater expression of LPAR1-3 and AX genes were detected in the healthy follicles compared to the atretic and transitional follicles (P < 0.05). The relative abundance of GDF9, BMP15, CTSZ and CTSB was also greater in COCs from healthy follicles than from transitional and atretic follicles (P < 0.05). It is postulated that the greater expression of LPARs and AX genes in healthy follicles compared with atretic follicles indicates an enhanced role of LPA in follicular development. Results of the present study also suggest the regulatory role of factors derived from the COCs in the growth and development of follicles. PMID- 29573845 TI - Co-occurrence graphs for word sense disambiguation in the biomedical domain. AB - Word sense disambiguation is a key step for many natural language processing tasks (e.g. summarization, text classification, relation extraction) and presents a challenge to any system that aims to process documents from the biomedical domain. In this paper, we present a new graph-based unsupervised technique to address this problem. The knowledge base used in this work is a graph built with co-occurrence information from medical concepts found in scientific abstracts, and hence adapted to the specific domain. Unlike other unsupervised approaches based on static graphs such as UMLS, in this work the knowledge base takes the context of the ambiguous terms into account. Abstracts downloaded from PubMed are used for building the graph and disambiguation is performed using the personalized PageRank algorithm. Evaluation is carried out over two test datasets widely explored in the literature. Different parameters of the system are also evaluated to test robustness and scalability. Results show that the system is able to outperform state-of-the-art knowledge-based systems, obtaining more than 10% of accuracy improvement in some cases, while only requiring minimal external resources. PMID- 29573846 TI - A Prospective Phase I/II Study of Docetaxel, Cisplatin and Continuous Capecitabine in Advanced Oesophago-Gastric Cancer (NWCOG-3). AB - AIMS: This open-label prospective phase I/II dose-escalation study determined the maximum tolerated dose (MTD) and then evaluated response, safety and feasibility of a novel combination of docetaxel, cisplatinum and capecitabine (DCC) in chemotherapy-naive patients with advanced oesophago-gastric carcinoma. MATERIALS AND METHODS: Patients with adenocarcinoma or squamous cell carcinoma of the oesophagus or stomach, of good performance status, deemed too advanced for curative treatment, were given systematically increasing doses of 3 weekly DCC to ascertain the MTD. Phase II administered up to six cycles of DCC at the MTD, assessing response and toxicity. RESULTS: Between November 2007 and November 2012, 15 patients were recruited into phase I and 41 into phase II. The MDT was a 21 day cycle of docetaxel 60 mg/m2 IV day 1, cisplatinum 60 mg/m2 IV day 1 and oral capecitabine 1000 mg/m2 daily in two divided doses for days 1-21. The most common phase II grade 3-4 toxicities were neutropenia 88% (10% febrile neutropenia), fatigue 15%, sensory neuropathy 10% and non-neutropenic infection 10%. The overall response rate was 51%, median progression-free survival was 7.4 months (confidence interval 6.7-9.4) and median overall survival was 10.9 months (confidence interval 7.7-13.7). CONCLUSION: DCC was tolerable and feasible with promising efficacy, and may be suitable for future investigation in both first line metastatic and neoadjuvant settings. PMID- 29573848 TI - Measurement properties of patient reported outcome measures for spondyloarthritis: A systematic review. AB - OBJECTIVES: This systematic review aimed to identify studies investigating measurement properties of patient reported outcome measures (PROMs) for spondyloarthritis (SpA), and to evaluate their methodological quality and level of evidence relating to the measurement properties of PROMs. METHODS: This systematic review was guided by the preferred reporting items for systematic review and meta-analysis (PRISMA). Articles published before 30 June 2017 were retrieved from PubMed(r), Embase(r), and PsychINFO(r) (Ovid). Methodological quality and level of evidence were evaluated according to recommendations from the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). RESULTS: We identified 60 unique PROMs from 125 studies in 39 countries. Twenty-one PROMs were validated for two or more SpA subtypes. The literature examined hypothesis testing (82.4%) most frequently followed by reliability (60.0%). A percentage of 77.7% and 42.7% of studies that assessed PROMs for hypothesis testing and reliability, respectively had "fair" or better methodological quality. Among the PROMs identified, 41.7% were studied in ankylosing spondylitis (AS) only and 23.3% were studied in psoriatic arthritis (PsA) only. The more extensively assessed PROMs included the ankylosing spondylitis quality of life (ASQoL) and bath ankylosing spondylitis functional index (BASFI) for ankylosing spondylitis, and the psoriatic arthritis quality of life questionnaire (VITACORA-19) for psoriatic arthritis. CONCLUSION: This study identified 60 unique PROMs through a systematic review and synthesized evidence of the measurement properties of the PROMs. There is a lack of validation of PROMs for use across SpA subtypes. Future studies may consider validating PROMs for use across different SpA subtypes. PMID- 29573849 TI - Dactylitis: A hallmark of psoriatic arthritis. AB - OBJECTIVE: Dactylitis-long considered a hallmark clinical feature of psoriatic arthritis (PsA)-occurs in 16-49% of patients with PsA. In this review, we discuss the pathology of dactylitis in PsA and clinical and imaging tools used to diagnose and monitor dactylitis. METHODS: PubMed literature searches were conducted using the terms psoriatic arthritis, dactylitis, pathology, imaging, ultrasound, magnetic resonance imaging, clinical, and indices. Articles were deemed relevant if they provided insight into the pathology, diagnosis, and/or monitoring of dactylitis in PsA, or if they discussed clinical or imaging indices used to assess dactylitis. RESULTS: Dactylitis in PsA often occurs asymmetrically, involves the feet more than the hands, and affects multiple digits simultaneously. Although dactylitis can be assessed clinically, imaging (radiography, ultrasound, magnetic resonance imaging, and bone scintigraphy) has provided key insights by documenting the various anatomic targets affected. Although inflammation can occur in most of the digital compartments, the nail has not been as well studied in dactylitic digits. Outcome measures for dactylitis range from dichotomous documentation to the Leeds dactylometer. Imaging outcome tools utilizing magnetic resonance imaging or ultrasound are under development. CONCLUSION: Dactylitis, which is associated with more erosive forms of PsA, is often the inaugural feature of PsA and may be the only feature for months to years. Early diagnosis and treatment of PsA favors better outcomes, possibly mitigating radiographic progression and destructive changes. Ultrasound and magnetic resonance imaging are useful tools that have not only shed light on the diverse tissues affected in dactylitis but can also be used to document ongoing inflammation. Ultrasound imaging dactylitis scores are being developed that will assist in diagnosing and documenting which compartments optimally respond to various treatment modalities. PMID- 29573847 TI - Granulocyte-macrophage colony-stimulating factor neuroprotective activities in Alzheimer's disease mice. AB - We investigated the effects of granulocyte-macrophage colony stimulating factor (GM-CSF) on behavioral and pathological outcomes in Alzheimer's disease (AD) and non-transgenic mice. GM-CSF treatment in AD mice reduced brain amyloidosis, increased plasma Abeta, and rescued cognitive impairment with increased hippocampal expression of calbindin and synaptophysin and increased levels of doublecortin-positive cells in the dentate gyrus. These data extend GM-CSF pleiotropic neuroprotection mechanisms in AD and include regulatory T cell mediated immunomodulation of microglial function, Abeta clearance, maintenance of synaptic integrity, and induction of neurogenesis. Together these data support further development of GM-CSF as a neuroprotective agent for AD. PMID- 29573850 TI - Clinical presentation of immune checkpoint inhibitor-induced inflammatory arthritis differs by immunotherapy regimen. AB - INTRODUCTION: Immune checkpoint inhibitors (ICIs) are a class of cancer immunotherapy, increasingly utilized to treat malignancies. Inflammatory arthritis (IA) is a potential consequence of ICI use, but there is limited information to guide evaluation and management of this immune-related adverse event (irAE). This study aimed to characterize clinical phenotypes, IA treatment and response in the largest cohort of patients with ICI-induced IA reported to date. METHODS: Patients with rheumatologist-confirmed IA occurring during or after ICI treatment with no prior history of autoimmune disease were included. Data were analyzed by ICI treatment regimen; treatments included combination CTLA 4/PD-1 inhibition, anti-PD-1 or anti-PD-L1 monotherapy. Relationship to the development of other irAEs, management of IA, and outcomes of IA management were evaluated. RESULTS: Of 30 patients identified, those treated with combination ICI therapy were more likely to present with knee arthritis, to have higher levels of C-reactive protein, to have already had another irAE, and to have a reactive arthritis-like phenotype. In contrast, patients treated with ICI monotherapy were more likely to have initial small joint involvement and to have IA as their only irAE. Ten patients required additional immunosuppression beyond corticosteroids, with TNF-inhibitors and/or methotrexate. Tumor progression while on non corticosteroid immunosuppression was not seen in those with initial tumor response to ICIs. CONCLUSION: These data suggest that distinct IA phenotypes may emerge with exposure to different ICI regimens. The majority of patients referred to rheumatology required systemic immunosuppression to manage their IA symptoms. Tumor progression was not seen in patients requiring TNF-inhibitors. PMID- 29573851 TI - The Use of Multivitamin/Multimineral Supplements: A Modified Delphi Consensus Panel Report. AB - PURPOSE: Evidence supporting the use of dietary supplements, in particular, multivitamin/multimineral supplements (MVMS), has been mixed, complicating the ability of health care professionals to recommend their use. To clarify the role that MVMS can play in supporting human health, a series of consensus statements was developed based on expert opinion. METHODS: A panel of 14 international experts in nutritional science and health care was convened to develop consensus statements related to using MVMS in supporting optimal human health. The modified Delphi process included 2 rounds of remote voting and a final round of voting at a roundtable meeting where evidence summaries were presented and discussed. The level of agreement with each of 9 statements was rated on a 5-point Likert scale: agree strongly; agree with reservation; undecided; disagree; or disagree strongly. Consensus was predefined as >=80% of the panel agreeing strongly or agreeing with reservation to a given statement. FINDINGS: Consensus was reached for all statements. The panel determined that MVMS can broadly improve micronutrient intakes when they contain at least the micronutrients that are consumed insufficiently or have limited bioavailability within a specified population. MVMS formulations may also be individualized according to age, sex, life cycle, and/or other selected characteristics. There are specific biological processes and health outcomes associated with deficient, inadequate, and adequate micronutrient levels. Adequate intake is necessary for normal biological functioning required for good health; in some instances, higher than recommended micronutrient intakes have the potential to provide additional health benefits. Meeting daily intakes established by dietary reference values should be an explicit public health goal for individuals and populations. Use of MVMS is one approach to ensure that adequate micronutrient needs are met in support of biological functions necessary to maintain health. Long-term use of MVMS not exceeding the upper limit of recommended intakes has been determined to be safe in healthy adults. There is insufficient evidence to indicate that MVMS are effective for the primary prevention of chronic medical conditions, including cardiovascular disease and cancer. However, for certain otherwise healthy subpopulations (eg, pregnant women, older adults) and some individuals with existing medical conditions who experience inadequacies in micronutrient intake, addressing inadequacies by using MVMS can provide health benefits. IMPLICATIONS: This consensus panel has described key issues related to the use of MVMS among individuals at risk of or presenting with inadequacies in micronutrient intake or biomarker status. PMID- 29573852 TI - Benefits and Challenges of Lung Cancer Screening in Older Adults. AB - PURPOSE: Lung cancer screening with low-dose computed tomography has been shown to significantly reduce lung cancer-related mortality in high-risk patients. However, patients diagnosed with lung cancer are typically older and often have multiple age- and smoking-related comorbidities. As a result, cancer screening in older adults remains a complex decision, requiring careful consideration of patients' risk characteristics and life expectancy to ensure that the benefits outweigh the risks of screening. In this review, we evaluate the evidence regarding lung cancer screening, with a focus on older patients. METHODS: PubMed was searched to identify relevant studies evaluating the clinical outcomes of lung cancer screening. The key words used in our search included non-small cell lung cancer (NSCLC), screening, older, comorbidities, computed tomography, and survival. While we primarily looked for articles specific to older patients, we also focused on subgroup analysis in older patients in larger studies. Finally, we reviewed all relevant guidelines regarding lung cancer screening. FINDINGS: Guidelines recommend that lung cancer screening be considered in adults aged 55 to 80 years who are at high risk based on smoking history (ie, 30-pack-year smoking history; having smoked within the past 15 years). Patients who fit these criteria have been shown to have a 20% reduction in lung cancer-related mortality with the use of low-dose computed tomography versus chest radiography. High rates of false-positive results and potential overdiagnoses were also observed. Therefore, screening is generally not recommended in adults with severe comorbidities or short life expectancy, who may experience limited benefit and higher risks with screening. However, several studies have shown a benefit with continued lung cancer screening with appropriate selection of older individuals at the highest risk and with the lowest comorbidities. IMPLICATIONS: Older patients experience the highest risk for lung cancer incidence and mortality, and stand to be the most likely to benefit from lung cancer screening. However, careful consideration must be given to higher rates of false-positives and overdiagnosis in this population, as well as tolerability of surgery and competing risks for death from other causes. The appropriate selection of older individuals for lung cancer screening can be greatly optimized by using validated risk-based targeting. PMID- 29573853 TI - Wildland firefighters and suicide risk: Examining the role of social disconnectedness. AB - Recent research has indicated that firefighters are at elevated suicide risk. Fire service organizations have called for research to examine fire service subgroups that might be at relatively increased suicide risk. Although anecdotal reports suggest that wildland firefighters represent one such group, to our knowledge, no study has empirically examined this conjecture. Thus, the present investigation examined if wildland firefighters report greater levels of suicide risk than non-wildland firefighters. Moreover, we sought to determine if two constructs proposed by the interpersonal theory of suicide to comprise suicidal desire-thwarted belongingness and perceived burdensomeness-statistically explain the link between wildland firefighter status and suicide risk. Merged data from two nationwide investigations of firefighter mental health were utilized (N = 1,131; 68.2% male, 89.4% White). A total of 1.8% (n = 20) of the sample identified as wildland firefighters. Compared to non-wildland firefighters, wildland firefighters reported greater levels of suicide risk. Thwarted belongingness, but not perceived burdensomeness, statistically explained this link. Findings suggest that programs enhancing social connectedness within the fire service, particularly among wildland firefighters, might be one avenue for suicide prevention among firefighters. Results of this novel investigation should be interpreted in light of the relatively small subgroup of wildland firefighters. PMID- 29573854 TI - Nitric oxide involvement in additive antidepressant-like effect of agmatine and lithium in mice forced swim test. AB - Lithium is still the main agent in the management of mood disorders such as depression. Likewise, agmatine protects the central nervous system (CNS) against depression. The aim of the present study was to examine the possible additive antidepressant-like effect of agmatine and lithium in mice forced swim test (FST) as well as exploration of the probable involvement of nitric oxide (NO) pathway in this response. Results showed that pretreatment with a subeffective dose of agmatine (0.01 mg/kg) augmented the antidepressant-like effect of lithium subeffective dose (3 mg/kg) (P < 0.001). L-NG-nitroarginine methyl ester (L-NAME, nonspecific nitric oxide synthase [NOS] inhibitor) at doses of 10 and 30 mg/kg, and 7-nitroindazole (7-NI, neuronal NOS inhibitor) at doses of 15 and 30 mg/kg potentiated the antidepressant-like effect of the subeffective combination of lithium (3 mg/kg) and agmatine (0.001 mg/kg) (P < 0.001, P < 0.01, respectively). However, various doses of aminoguanidine (25 and 50 mg/kg, inducible NOS inhibitor) failed to alter the immobility time of the same combination (P > 0.05). Moreover, pretreatment with subeffective doses of L-arginine (substrate for NOS, 300 and 750 mg/kg) reversed the augmenting antidepressant-like effect of agmatine (0.01 mg/kg) on lithium (3 mg/kg) (P < 0.001). Our results revealed that agmatine enhances the antidepressant-like effects of lithium and the NO pathway might mediate this phenomenon. In addition, constitutive NOS plays a dramatic role in this response. PMID- 29573855 TI - Sleep at night and association to aggressive behaviour; Patients in a Psychiatric Intensive Care Unit. AB - Evaluations of associations between sleep at night and aggressive behaviour in Psychiatric Intensive Care Units (PICU) are lacking. The aims were to explore if sleep duration or night-to-night variations in sleep duration correlated with aggressive behaviour and aggressive incidents the next day and through the whole admission. Fifty consecutive patients admitted to a PICU were included (521 nights) and the nurses registered the time patients were sleeping, aggressive behaviour with The Broset Violence Checklist (BVC) and aggressive incidents with The Staff Observation Aggression Scale-Revised (SOAS-R). At admission, short sleep duration the first night correlated with aggressive behaviour the next day and admissions with violent incidents had a median of 4.0 h difference in sleep from night one to night two compared to 2.1 h for the rest of the admissions. During the stay, large absolute difference in sleep duration between two nights correlated with aggressive behaviour the next day and short sleep duration was associated with violent incidents. Short sleep duration and night-to-night variations in sleep duration are both associated with increased risk for aggression in PICUs. This observation might help to predict and prevent aggressive incidents. PMID- 29573856 TI - [Scleral abnormalities in high myopic posterior staphyloma on swept-source ocular coherence tomography]. PMID- 29573857 TI - [Oculoplastic complications of the excision of meningiomas with orbital extension]. AB - INTRODUCTION: Meningiomas with orbital extension are the most frequent benign orbital tumors. The few studies available on the postoperative complications of their excision focus on the postoperative evolution of proptosis, visual acuity and visual field deficits. The goal of our study was to highlight the oculoplastic complications secondary to their excision. MATERIAL AND METHOD: We identified all cases of meningiomas with orbital extension undergoing excision either neurosurgically or via an orbital approach in the ophthalmology and neurosurgery departments of Pasteur university medical center in Nice between February 2011 and January 2017. The data collection included the postoperative presence of proptosis, oculomotor disturbance, lid disorders, dry eye and trigeminal nerve damage. RESULTS: Twenty-nine patients were included; 89.7 % were women. The mean age was 55 years. Postoperative complications included 25 % residual proptosis; 40.7 % oculomotor disturbance, 75 % of which regressed at least partially; 50 % ptosis, 21 % of which did not regress; 40 % dry eye; and in 21.4 % the trigeminal nerve was involved. CONCLUSION: The management of meningiomas with orbital extension is difficult due to their anatomical location and requires joint neurosurgical and oculoplastic management. Sufficient follow up is required before recommending surgery for oculomotor disturbances. The frequency of occurrence of ptosis with potential recommendation for surgery requires caution given the occurrence of trigeminal nerve involvement and dry eye syndrome. PMID- 29573858 TI - [Evaluation of the quality of life of patients fitted with scleral lenses using a Moroccan version of NEI-VFQ 25]. AB - PURPOSE: To evaluate the contribution of scleral lenses in terms of improving quality of life and vision. METHODS: We conducted a retrospective study of the quality of life (QOL) of patients fitted with scleral lenses, between November 2015 and November 2016 in the Marrakech university hospital department of ophthalmology. QOL was assessed before and after scleral lens (ICD) adaptation using a version of the National Eye Institute Visual Function Questionnaire 25 translated into the Moroccan dialect of Arabic. RESULTS: We included 48 patients (68 eyes). The main indications included severe corneal ectasia followed by post keratoplasty eyes, post-traumatic corneas and patients with ocular surface disease. The average duration of scleral lens wear was 6 months, and the average wearing time was 12hours per day. BCVA increased from 0.8 to 0.2+/-0.5 LOGMAR. The average scores on the NEI-VFQ 25 of patients after scleral lens fitting were significantly higher, 80.5 versus 42.6 before wearing scleral lenses, thus an increase of 38.1. DISCUSSION: Quality of life has become a major issue in the healthcare field, which has seen a renewed interest in ophthalmology lately. The results of our study support the data from previous studies regarding the impact of scleral lenses on the quality of life of patients. CONCLUSION: High oxygen permeability scleral lenses are a satisfying therapeutic alternative, allowing a significant improvement in the quality of life of patients for whom the usual therapeutic means are limited. PMID- 29573859 TI - [Persistent pupillary membrane]. PMID- 29573860 TI - ? AB - New anticancer therapies, immune pathway inhibitors, may cause immune-related adverse events (IRAE). Immune-related ocular toxicities are rare but are potentially serious adverse events. The purpose of this article is to report a case of ocular inflammatory involvement potentially related to the immune response and the use of nivolumab, a new immunologic agent used for the treatment of a solid tumor. Despite the implication of this therapy in the occurrence of inflammation, other causes must always be ruled out. It is possible to continue this therapy in consideration of the risk/benefit ratio for each patient. Close collaboration between oncologists and ophthalmologists is necessary in the diagnosis and timely management of IRAE related to these new emerging therapies.

AB - All the components of the ocular surface and the lacrimal system are affected by aging. Aging induces lacrimal gland fibrosis, Meibomian gland dysfunction, loss of corneal sensitivity, decreased corneal cell density, impairment of immune defences, increased local inflammation associated with hormonal changes, conjunctivochalasis, lid abnormalities, etc. Furthermore, homeostasis of the ocular surface may be altered by various age-related systemic comorbidities and iatrogenic interventions. Altogether, aging is considered the most predominant risk factor for dry eye disease. The increasing knowledge of the pathophysiology of aging of the ocular surface allows for refinement of the management of ocular surface disease in the elderly. PMID- 29573863 TI - [Comparison of objective optical quality measured by double-pass aberrometry in patients with moderate dry eye: Normal saline vs. artificial tears: A pilot study]. AB - Dry eye is defined by a tear film instability resulting in variable but systematic fluctuations in the quality of vision. Variability in optical quality can be demonstrated using a double pass aberrometer such as the OQAS (Optical Quality Analyzing System, Visiometrics). The goal of this work is to compare fluctuations in objective quality of vision measured by OQAS between treatment with normal saline eye drops and treatment with carmellose 0.5% and hyaluronic acid 0.1% (Optive Fusion [OF], Allergan) in patients with moderate dry eye syndrome. Optical quality was measured by evaluating the variations in the Optical Scattering Index (OSI) over 20seconds using the OQAS. Inclusion criteria were dry eye syndrome with an Ocular Surface Disease Index (OSDI) score>23 treated only with artificial tears. The patients were their own controls: OF in one eye and normal saline in the fellow eye. The choice of the subject eye and control eye was determined in a randomized fashion. OSI variations were measured in each eye before instillation, 5minutes and 2hours after instillation. The primary endpoint was OSI fluctuation over 20seconds of measurement. Secondary endpoints were the number of blinks and patient's preference (preferred eye). Preliminary results were obtained on 19 patients. Average OSDI score was 36.8. Visual acuity was 10/10 with no significant difference between the two eyes. Prior to instillation, there was no significant difference between "normal saline" and "OF" eyes in terms of OSI, OSI variability or number of blinks. In the normal saline eye, there was no significant variation in mean OSI, OSI variability, OSI slope, or number of blinks. However, in the "OF" eye, there was a significant variation between initial and 2-hour OSI variability (0.363 versus 0.204; P<0.05), the average slope of OSI (0.04 versus 0.01; P<0.05) and the number of blinks (4.2 versus 2.8; P<0.05). Sixty-five percent of patients preferred the OF eye, 24% did not have a preference, and 11% preferred the normal saline eye. Objective quality of vision measured by OQAS is an interesting parameter for evaluating the effectiveness of a lacrimal substitute. The purpose of artificial tears is, among other things, to provide comfort and a reduction of dry eye symptoms such as poor quality of vision. This study demonstrates that 0.5% carmellose and 0.1% hyaluronic acid allowed better stabilization of the tear film and thus a significant improvement in the quality of vision compared to normal saline. PMID- 29573864 TI - Minimally invasive distal linear metatarsal osteotomy combined with selective release of lateral soft tissue for severe hallux valgus. AB - BACKGROUND: Minimally invasive techniques for hallux valgus have been widely used to treat mild to moderate hallux valgus deformities. The purpose of this study was to evaluate the clinical and radiographic outcomes of distal linear metatarsal osteotomy (DLMO), which is one of the minimally invasive techniques, for severe hallux valgus. METHODS: 95 patients (141 feet) with severe hallux valgus underwent DLMOs. Lateral soft tissue release (LSTR) was performed at the same time for the cases selected by an original manual test. The satisfaction level, the Japanese Society of Surgery of the Foot (JSSF) hallux scale score, and weight-bearing radiographs of the foot were assessed preoperatively and after more than 24 months. In addition, the clinical and radiographic outcomes were compared among three groups divided by the kind of LSTR: no LSTR; manual correction; and open release through skin incision. RESULTS: Although the first metatarsal bone was significantly shortened, dorsiflexed, and elevated on postoperative radiographs, the rate of satisfaction was 87.2% (123/141), and the mean JSSF hallux scale score improved significantly from 60.4 (44-73) to 90.4 (65 100). The mean hallux valgus and intermetatarsal angles also improved significantly from 45.5 degrees (40.0-60.0 degrees ) to 10.3 degrees (-28.0 40.9 degrees ) and from 19.9 degrees (14.0-28.7 degrees ) to 8.3 degrees (-1.6 18.5 degrees ), respectively. Delayed union (18 feet), metatarsalgia (16 feet), recurrence (22 feet), and hallux varus (22 feet) were observed, and they were more obvious in DLMO combined with open release through a skin incision. CONCLUSIONS: DLMO combined selectively with LSTR is an effective procedure for correcting severe hallux valgus. However, the indication for open release with DLMO should be considered carefully. PMID- 29573865 TI - Metastasis-associated protein 1 (MTA1) in gastric cancer tissues is positively associated with poorer prognosis. AB - BACKGROUND: The present study examined the clinical significance of metastasis associated protein 1 (MTA1) in the progression and patient survival of gastric cancer. METHODS: Paraffin-embedded resected tissues of gastric cancer mucosa (n = 436) and adjacent normal mucosa (n = 92) were assessed immunohistochemically for MTA1 protein, and scored according to the percentage of cells positively stained for MTA1 combined with stain intensity. Associations between MTA1 staining scores and clinicopathological factors, including survival time, were evaluated. RESULTS: The staining scores for MTA1 were significantly higher in gastric cancer tissues than in matched normal tissues. MTA1 scores positively correlated with tumor size, depth of invasion, presence of lymph node metastasis, lymphatic involvement, venous invasion, distal metastasis, and advanced clinical staging. Patients with high MTA1 scores in gastric cancer tissues had a significantly lower five-year survival rate compared with patients with low MTA1 scores. The multivariate analysis indicated that MTA1 protein levels in resected gastric cancer tissues, as reflected by immunohistochemical staining, are an independent prognostic index of gastric carcinoma (P < 0.01). CONCLUSION: MTA1 immunopositivity was significantly associated with progression of gastric cancer, and may be helpful in gastric cancer prognosis.

PMID- 29573867 TI - Brain-derived neurotrophic factor induces angiogenin secretion and nuclear translocation in human umbilical vein endothelial cells. AB - Brain-derived neurotrophic factor (BDNF) is a well-known humoral protein that induces growth of neurons. Recent studies have suggested that BDNF could act as an angiogenesis inducer similar to vascular endothelial growth factor (VEGF). Angiogenin is a strong mediator of angiogenesis. It has particular characteristics both as a secreted protein and a transcription factor. After being incorporated into the cytoplasm, angiogenin is immediately transferred to the nucleus and then mediates the angiogenic effects of angiogenesis inducers, including VEGF. The aim of this study is to determine the association between BDNF and angiogenin. At first, we determined the secretion of angiogenin from human umbilical vein endothelial cells (HUVEC) induced by BDNF with enzyme-linked immunosorbent assay. Next, we determined BDNF-induced nuclear translocation of angiogenin by immunofluorescent staining. In addition, we examined the mRNA expression of angiogenin in HUVEC before and after BDNF stimulation by quantitative reverse transcriptase-polymerase chain reaction. As a result, we noted that BDNF induced angiogenin secretion and nuclear translocation without an increase in the mRNA expression in HUVEC. Furthermore, we demonstrated that BDNF induced HUVEC proliferation was significantly suppressed when neomycin, a specific inhibitor of nuclear translocation of angiogenin, was administered. These findings indicate that nuclear translocation of angiogenin is critically involved in BDNF-induced proliferation of HUVEC. In conclusion, angiogenin contributes to angiogenesis induced by BDNF.

PMID- 29573870 TI - What low back pain is and why we need to pay attention. AB - Low back pain is a very common symptom. It occurs in high-income, middle-income, and low-income countries and all age groups from children to the elderly population. Globally, years lived with disability caused by low back pain increased by 54% between 1990 and 2015, mainly because of population increase and ageing, with the biggest increase seen in low-income and middle-income countries. Low back pain is now the leading cause of disability worldwide. For nearly all people with low back pain, it is not possible to identify a specific nociceptive cause. Only a small proportion of people have a well understood pathological cause-eg, a vertebral fracture, malignancy, or infection. People with physically demanding jobs, physical and mental comorbidities, smokers, and obese individuals are at greatest risk of reporting low back pain. Disabling low back pain is over represented among people with low socioeconomic status. Most people with new episodes of low back pain recover quickly; however, recurrence is common and in a small proportion of people, low back pain becomes persistent and disabling. Initial high pain intensity, psychological distress, and accompanying pain at multiple body sites increases the risk of persistent disabling low back pain. Increasing evidence shows that central pain-modulating mechanisms and pain cognitions have important roles in the development of persistent disabling low back pain. Cost, health-care use, and disability from low back pain vary substantially between countries and are influenced by local culture and social systems, as well as by beliefs about cause and effect. Disability and costs attributed to low back pain are projected to increase in coming decades, in particular in low-income and middle-income countries, where health and other systems are often fragile and not equipped to cope with this growing burden. Intensified research efforts and global initiatives are clearly needed to address the burden of low back pain as a public health problem. PMID- 29573871 TI - Low back pain: a call for action. AB - Low back pain is the leading worldwide cause of years lost to disability and its burden is growing alongside the increasing and ageing population.1 Because these population shifts are more rapid in low-income and middle-income countries, where adequate resources to address the problem might not exist, the effects will probably be more extreme in these regions. Most low back pain is unrelated to specific identifiable spinal abnormalities, and our Viewpoint, the third paper in this Lancet Series,2,3 is a call for action on this global problem of low back pain. PMID- 29573873 TI - CT-based Morphometric Analysis of Professional Opera Singers' Vocal Folds. AB - PURPOSE AND STUDY DESIGN: Our work aimed to study the relationship between the length of vocal folds and classical voice type among professional opera singers. Also, the present paper attempts to assess if individual features such as height and body mass index are associated with the vocal folds length (VFL) and the vocal range. Our research compared VFL and voice type by evaluation of neck computed tomography imaging of professional opera singers obtained between 2009 and 2015. Vocal range was measured after scanning procedure by a speech-language pathologist. The results were used to compare VFL with vocal range, voice type, and individual features of every singer. MATERIAL AND METHODS: The group included 93 opera singers (female: 31 sopranos, 15 mezzos, and 5 contraltos; male: 17 tenors, 16 baritones, 6 basses, and 3 countertenors). Different values such as VFL, vocal range, and individuals' features (height, weight, body mass index) were analyzed statistically. RESULTS: Some significant differences and correlation were found. The VFL was diversified between classical voice types. VFL for soprano, mezzo-soprano, and bass was significantly different from every other type of voice. The vocal range has been shown to have a negative correlation with VFL value, which reflects the narrowest vocal range among bass voices. The analysis confirmed a linear correlation between VFL and individual features of the body such as height and body mass index. CONCLUSION: Presented data support the hypothesis that there are significant differences of VFL, vocal range, and body morphology between professional singers of different voice classification. PMID- 29573872 TI - Prevention and treatment of low back pain: evidence, challenges, and promising directions. AB - Many clinical practice guidelines recommend similar approaches for the assessment and management of low back pain. Recommendations include use of a biopsychosocial framework to guide management with initial non-pharmacological treatment, including education that supports self-management and resumption of normal activities and exercise, and psychological programmes for those with persistent symptoms. Guidelines recommend prudent use of medication, imaging, and surgery. The recommendations are based on trials almost exclusively from high-income countries, focused mainly on treatments rather than on prevention, with limited data for cost-effectiveness. However, globally, gaps between evidence and practice exist, with limited use of recommended first-line treatments and inappropriately high use of imaging, rest, opioids, spinal injections, and surgery. Doing more of the same will not reduce back-related disability or its long-term consequences. The advances with the greatest potential are arguably those that align practice with the evidence, reduce the focus on spinal abnormalities, and ensure promotion of activity and function, including work participation. We have identified effective, promising, or emerging solutions that could offer new directions, but that need greater attention and further research to determine if they are appropriate for large-scale implementation. These potential solutions include focused strategies to implement best practice, the redesign of clinical pathways, integrated health and occupational interventions to reduce work disability, changes in compensation and disability claims policies, and public health and prevention strategies. PMID- 29573874 TI - A multi-country study of dengue vaccination strategies with Dengvaxia and a future vaccine candidate in three dengue-endemic countries: Vietnam, Thailand, and Colombia. AB - BACKGROUND: The dengue vaccination era began when Dengvaxia (CYD-TDV) became available in 2016. In addition, several second-generation vaccine candidates are currently in phase 3 trials, suggesting that a broader availability of dengue vaccines may be possible in the near future. Advancing on the recent WHO-SAGE recommendations for the safe and effective use of CYD-TDV at the regional level on average, this study investigates the vaccination impacts and cost effectiveness of CYD-TDV and of a hypothetical new vaccine candidate (NVC) in a country-specific manner for three endemic countries: Vietnam, Thailand, and Colombia. METHODS: The vaccination impacts of CYD-TDV and NVC were derived by fitting the empirical seroprevalence rates of 9 year olds into an individual based meta-population transmission model, previously used for the WHO-SAGE working group. The disability-adjusted life years were estimated by applying country-specific parametric values. The cost-effectiveness analyses of four intervention strategies in combination with routine and catch-up campaigns were compared for both vaccines to inform decision makers regarding the most suitable immunization program in each of the three countries. RESULTS AND CONCLUSION: Both CYD-TDV and NVC could be cost-effective at the DALY threshold cost of $2000 depending upon vaccination costs. With CYD-TDV, targeting 9 year olds in routine vaccination programs and 10-29 year olds as a one-off catch-up campaign was the most cost-effective strategy in all three countries. With NVC, while the most cost-effective strategy was to vaccinate 9-29 and 9-18 year olds in Vietnam and Thailand respectively, vaccinating younger age cohorts between 1 and 5 years old in Colombia was more cost-effective than other strategies. Given that three countries will soon face decisions regarding whether and how to incorporate CYD TDV or future dengue vaccines into their budget-constrained national immunization programs, the current study outcomes can be used to help decision makers understand the expected impacts and cost-effectiveness of such vaccines. PMID- 29573875 TI - Immunotherapeutic potential of Leishmania (Leishmania) donovani Th1 stimulatory proteins against experimental visceral leishmaniasis. AB - An effective therapeutic vaccination strategy is required for controlling visceral leishmaniasis (VL), a fatal systemic disease, through boosting the immunosuppressed state in Leishmania-infected individuals, as the majority of them living in the endemic regions exhibit either subclinical or asymptomatic infection which further often develops into a full-blown disease. Previously in our laboratory, several Th1 stimulatory recombinant proteins were successfully cloned, purified and assessed for their prophylactic efficacy against Leishmania challenge. Due to their immunostimulatory property, these proteins are needed to be evaluated for their immunotherapeutic potential in Leishmania-infected hamsters. Four proteins namely, aldolase, enolase, p45 and triose phosphate isomerase were taken up to immunize animals at different doses (50, 25 and 12.5 MUg/animal). Immunization with lower doses of aldolase and enolase, i.e., 25 and 12.5 MUg showed a significant decline (~60%) in parasitic load along with an enhanced cellular immune response. These findings indicate that vaccination with above -stated Th1 stimulatory proteins is an effective immunotherapeutic approach against experimental VL. However, their efficacies may further be improved in combination with known therapeutic regimens or immunomodulators. PMID- 29573876 TI - Humoral immunity 10 years after booster immunization with an adolescent and adult formulation combined tetanus, diphtheria, and 5-component acellular pertussis vaccine in the USA. AB - BACKGROUND: In a prospective, randomized pivotal phase III clinical trial, the immunogenicity and reactogenicity of a tetanus-diphtheria-acellular pertussis vaccine (Tdap) and a tetanus-diphtheria vaccine (Td) vaccine were studied in participants aged 11-64 years. Here we report antibody persistence through 10 years after vaccination. METHODS: Participants who received Tdap or Td in the original phase III trial and provided pre- and post-vaccination serum samples were recruited to donate sera at 1, 3, 5 and 10 years post-vaccination. Antibody concentrations were measured using standard assay techniques. RESULTS: Initially, 1457 Tdap and 1152 Td recipients were included; of these, 175 persons from Tdap group were available at the final study bleed point. Nearly all adolescents in both groups had diphtheria antibody levels >=0.1 IU/mL 1 month after vaccination, which were maintained in >=95% of vaccinees at 5 and 10 years. Among adults, >=94% had diphtheria antibody levels >=0.1 IU/mL 1 month after vaccination, which were maintained in >=80% at 5 and 10 years. Nearly all participants had tetanus antibodies >=0.1 IU/mL throughout the study. PT antibodies declined to pre vaccination levels approximately 5 years post-vaccination; FHA, PRN and FIM antibodies waned at 5 and 10 years but remained several-fold higher than pre vaccination levels. CONCLUSIONS: Tdap and Td provide long-lasting protective immune responses against diphtheria and tetanus. Pertussis antibodies following Tdap generally exceeded pre-vaccination levels throughout the study, but showed substantial waning. These data may inform discussion of the need for repeat Tdap booster vaccinations among adults. TRIAL REGISTRATION: The original phase III clinical trial, as well as the 1-, 3-, and 5-year serology follow-up studies were conducted prior to mandatory registration. The 10-year serology follow-up data collection was performed as part of a repeat Tdap administration clinical trial that was registered under clinicaltrials.gov number NCT01439165. PMID- 29573877 TI - T-cell responses against Malaria: Effect of parasite antigen diversity and relevance for vaccine development. AB - The on-going agenda for global malaria elimination will require the development of additional disease control and prevention measures since currently available tools are showing signs of inadequacy. Malaria vaccines are seen as one such important addition to the control arsenal since vaccines have proven to be highly effective public health tools against important human diseases. Both cell mediated and antibody responses are generally believed to be important for malaria parasite control, although the exact targets of T and B cell responses against malaria have not been clearly defined. However, our current understanding of the immune response to malaria suggests that T cell responses against multiple antigenic targets may potentially be key for the development of a highly efficacious malaria vaccine. This review takes a comprehensive look at the available literature on T cell-mediated immunity against all human stages of the malaria parasite and the effect of antigen diversity on these responses. The implications of these interrelationships for the development of an effective vaccine for malaria are also highlighted. PMID- 29573878 TI - Long-term immunity to hepatitis B following vaccination in infancy: Real-world data analysis. AB - BACKGROUND: Hepatitis B virus (HBV) vaccination has decreased the prevalence of chronic HBV infections and their sequelae. However, whether vaccination at birth provides lifelong protection is unclear. OBJECTIVE: To assess long-term immunity following neonatal HBV immunization in a large population-based cohort. METHODS: Using the database of a 2 million member sick fund in Israel, we identified all subjects born after introduction of universal HBV vaccination in Israel (January 1992 through December 2014), that were tested for hepatitis B surface antibody (anti-HBs Ab's). Years since vaccination were categorized into 5-year groups and linear trends in the seroprevalence of HBV immunity were calculated. Anamnestic response and presence of Hepatitis B surface antigen (HBs Ag) were assessed. RESULTS: Included were 20,634 tested individuals. Mean (+/-SD) age at testing was 14.8 (+/-5.4) years. Mean anti-HBs Ab levels declined with time to 16.39 mIU/ml in the 15-20 year group (P < 0.001). The proportion of negative results increased gradually (P < 0.001) to 66.7% after 15 years. Anamnestic response assessment showed that 604 of 644 seronegative subjects (93.8%, 95% CI: 91.6-95.5%) became seropositive after a booster dose. HBs Ag was identified in 91 of the 20,634 (4.4 per 1000 study participants). CONCLUSIONS: Following vaccination, anti-HB's Ab's progressively decline, with only a third of the population retaining protective levels after 15 years. In adolescence, anamnestic response shows that nearly all revaccinated adolescents exhibit immunity. A low rate of Hepatitis B infection was demonstrated despite vaccination of nearly all newborns. PMID- 29573879 TI - Preclinical and clinical otoprotective applications of cell-penetrating peptide D JNKI-1 (AM-111). AB - There is a growing interest in the auditory community to develop novel prophylactic and therapeutic drugs to prevent permanent sensorineural hearing loss following acute cochlear injury. The jun-N-terminal protein kinase (JNK) pathway plays a crucial role in acute sensory hearing loss. Blocking the JNK pathway using the cell-penetrating peptide D-JNKI-1 (AM-111/brimapitide) has shown promise as both a prophylactic and therapeutic agent for acute cochlear injury. A number of pre-clinical and clinical studies have determined the impact of D-JNKI-1 on acute sensorineural hearing loss. Given the inner-ear selective therapeutic profile, local route of administration, and ability to diffuse across cellular membranes rapidly using both active and passive transport makes D-JNK-1 a promising oto-protective drug. In this review article, we discuss the application of D-JNKI-1 in various auditory disorders as well as its pharmacological properties and distribution in the cochlea. PMID- 29573881 TI - Auditory and language outcomes in children with unilateral hearing loss. AB - OBJECTIVES: Children with unilateral hearing loss (UHL) are being diagnosed at younger ages because of newborn hearing screening. Historically, they have been considered at risk for difficulties in listening and language development. Little information is available on contemporary cohorts of children identified in the early months of life. We examined auditory and language acquisition outcomes in a contemporary cohort of early-identified children with UHL and compared their outcomes at preschool age with peers with mild bilateral loss and with normal hearing. DESIGN: As part of the Mild and Unilateral Hearing Loss in Children Study, we collected auditory and spoken language outcomes on children with unilateral, bilateral hearing loss and with normal hearing over a four-year period. This report provides a cross-sectional analysis of results at age 48 months. A total of 120 children (38 unilateral and 31 bilateral mild, 51 normal hearing) were enrolled in the study from 2010 to 2015. Children started the study at varying ages between 12 and 36 months of age and were followed until age 36-48 months. The median age of identification of hearing loss was 3.4 months (IQR: 2.0, 5.5) for unilateral and 3.6 months (IQR: 2.7, 5.9) for the mild bilateral group. Families completed an intake form at enrolment to provide baseline child and family-related characteristics. Data on amplification fitting and use were collected via parent questionnaires at each annual assessment interval. This study involved a range of auditory development and language measures. For this report, we focus on the end of follow-up results from two auditory development questionnaires and three standardized speech-language assessments. Assessments included in this report were completed at a median age of 47.8 months (IQR: 38.8, 48.5). Using ANOVA, we examined auditory and language outcomes in children with UHL and compared their scores to children with mild bilateral hearing loss and those with normal hearing. RESULTS: On most measures, children with UHL performed poorer than those in the mild bilateral and normal hearing study groups. All children with hearing loss performed at lower levels compared to the normal hearing control group. However, mean standard scores for the normal hearing group in this study were above normative means for the language measures. In particular, children with UHL showed gaps compared to the normal hearing control group in functional auditory listening and in receptive and expressive language skills (three quarters of one standard deviation below) at age 48 months. Their performance in receptive vocabulary and speech production was not significantly different from that of their hearing peers. CONCLUSIONS: Even when identified in the first months of life, children with UHL show a tendency to lag behind their normal hearing peers in functional auditory listening and in receptive and expressive language development. PMID- 29573880 TI - Responses of neurons in the feline inferior colliculus to modulated electrical stimuli applied on and within the ventral cochlear nucleus; Implications for an advanced auditory brainstem implant. AB - Auditory brainstem implants (ABIs) can restore useful hearing to persons with deafness who cannot benefit from cochlear implants. However, the quality of hearing restored by ABIs rarely is comparable to that provided by cochlear implants in persons for whom those are appropriate. In an animal model, we evaluated elements of a prototype of an ABI in which the functions of macroelectrodes on the surface of the dorsal cochlear nucleus would be integrated with the function of multiple penetrating microelectrodes implanted into the ventral cochlear nucleus. The surface electrodes would convey most of the range of loudness percepts while the intranuclear microelectrodes would sharpen and focus pitch percepts. In the present study, stimulating electrodes were implanted chronically on the surface of the animal's dorsal cochlear nucleus (DCN) and also within their ventral cochlear nucleus (VCN). Recording microelectrodes were implanted into the central nucleus of the inferior colliculus (ICC). The electrical stimuli were sinusoidally modulated stimulus pulse trains applied on the DCN and within the VCN. Temporal encoding of neuronal responses was quantified as vector strength (VS) and as full-cycle rate of neuronal activity in the ICC. VS and full-cycle AP rate were measured for 4 stimulation modes; continuous and transient amplitude modulation of the stimulus pulse trains, each delivered via the macroelectrode on the surface of the DCN and then by the intranuclear penetrating microelectrodes. In the proposed clinical device the functions of the surface and intranuclear microelectrodes could best be integrated if there is minimal variation in the neuronal responses across the range of modulation depth, modulation frequencies, and across the four stimulation modes. In this study VS did vary as much as 34% across modulation frequency and modulation depth within a stimulation mode, and up to 40% between modulation modes. However, these intra- and inter-mode variances differed for different stimulation rates, and at 500 Hz the inter-mode differences in VS and across the range of modulation frequencies and modulation depths was = 24% and the intra-modal differences were = 15%. The findings were generally similar for rate encoding of modulation depth, although the depth of transient amplitude modulation delivered by the surface electrode was weakly encoded as full-cycle rate. Overall, our findings support the concept of a clinical ABI that employs surface stimulation and intranuclear microstimulation in an integrated manner. PMID- 29573883 TI - Sexual Violence on Campus: Differences Across Gender and Sexual Minority Status. AB - PURPOSE: Sexual violence is a pervasive problem on university campuses. Although previous work has documented greater vulnerability for sexual violence among sexual and gender minority students, little is known about contextual variation in vulnerability to this kind of violence. The goals of the current study were (1) to identify vulnerability among sexual and gender minority students with regard to sexual violence, and (2) to explore if the context of this violence differs across sexual and gender minority status. METHODS: Undergraduate students (ages 18-24) from six francophone universities in Quebec, Canada (N = 4,264) completed online questionnaires regarding their experience of sexual violence, as well as the context of these acts (e.g., the gender of the perpetrator, the status of the perpetrator, and the location of the violence). They also provided information regarding their sexual and gender minority status. Binary logistic regressions were conducted to assess for variation in experiencing sexual violence across sexual and gender minority status. RESULTS: Transgender/nonbinary students generally reported higher levels of sexual violence than their cisgender peers, while variation occurred with regard to vulnerability across sexual identity subgroups. Few differences in context were observed across sexual minority identity. Transgender/nonbinary students were significantly more likely to report sexual violence in athletic contexts and during volunteering activities compared to their cisgender peers. CONCLUSIONS: Findings highlight the higher levels of vulnerability for sexual violence among gender minority and some sexual minority university students. They also point to the contexts in which such violence occurs, suggesting specific strategies for prevention. PMID- 29573882 TI - Unraveling the Structure and Mechanism of the MST(ery) Enzymes. AB - The menaquinone, siderophore, and tryptophan (MST) enzymes transform chorismate to generate precursor molecules for the biosynthetic pathways defined in their name. Kinetic data, both steady-state and transient-state, and X-ray crystal structures indicate that these enzymes are highly conserved both in mechanism and in structure. Because these enzymes are found in pathogens but not in humans, there is considerable interest in these enzymes as drug design targets. While great progress has been made in defining enzyme structure and mechanism, inhibitor design has lagged behind. This review provides a detailed description of the evidence that begins to unravel the mystery of how the MST enzymes work, and how that information has been used in inhibitor design. PMID- 29573884 TI - Ten years of research with the Socially Evaluated Cold Pressor Test: Data from the past and guidelines for the future. AB - Ten years ago, the Socially Evaluated Cold Pressor Test (SECPT) was introduced as a standardized protocol for the efficient experimental stress induction in humans. In short, the 3 min SECPT, which can be conducted by only a single experimenter, combines a physiological challenge (hand immersion into ice water) with socio-evaluative elements. The purpose of this article is twofold. First, we aim to evaluate the subjective and physiological responses elicited by the SECPT. To this end, we pooled data from 21 studies from our lab and systematically analyzed the response profile to the SECPT. Our analyses show that the SECPT leads, both in men and women, to striking increases in subjective stress levels, autonomic arousal, and cortisol, albeit the cortisol response is typically somewhat less pronounced than in the Trier Social Stress Test. Second, we aim to provide guidelines for conducting the SECPT, in order to foster homogenization of the SECPT procedure across (and within) labs. In sum, we argue that the SECPT is a highly efficient tool to induce stress and activate major stress systems in a laboratory context, in particular if the guidelines that we outline here are followed. PMID- 29573885 TI - Use of bilaminar grafts as life-saving interventions for severe burns: A single center experience. AB - BACKGROUND: Skin coverage remains a significant hurdle in large-sized burns. Recent advances have allowed to grow Bilaminar Cultured Skin Autografts (BCSGs) from patients' own donor sites. The aim of this study was to report long-term outcomes in patients with large-sized burns having received BCSGs. METHODS: Nine patients received BCSGs from January 2010 to May 2015. Except one patient who died during hospitalization, all patients were contacted. Four agreed to partake in the study. Patients were tested with the Vancouver Scar Scale (VSS), QuickDASH questionnaire and Burn Specific Health Scale (BSHS). Incisional biopsies of BCSGs were compared with patients' autografts. RESULTS: From nine patients, mean age was 40 years and mean TBSA was 70.3%. For the four patients included, score averaged was 2.25 on the VSS, 29.5 on QuickDASH, 36/36 for psychosocial items and 63/84 for functional abilities on the BSHS. Compared with autografts, BCSGs demonstrated better pliability VSS and functionality. Biopsies showed no evidence of malignancy or atypical changes, but areas of hyperpigmentation. CONCLUSION: This is the first report investigating the long-term outcome of a newly developed BCSG. BCSGs demonstrated comparable results with patients' autografts, functional outcomes on self-reported questionnaires and excellent psychological states. Precaution given the extensive unexpected hyperpigmentation must be taken and a randomized controlled study is underway.

AB - This work introduces biodiesel production from wet spent coffee grounds (SCGs) with supercritical methanol without any pre-drying process. Supercritical methanol and subcritical water effectively produced biodiesel via in situ transesterification by inducing more porous SCG and enhancing the efficiency of lipid extraction and conversion. It was also found that space loading was one of the critical factors for biodiesel production. An optimal biodiesel yield of 10.17 wt% of dry SCG mass (86.33 w/w% of esterifiable lipids in SCG) was obtained at reaction conditions of 270 degrees C, 90 bars, methanol to wet SCG ratio 5:1, space loading 58.4 ml/g and reaction time 20 min. Direct use of wet SCG waste as feedstock for supercritical biodiesel production eliminates the conventional dying process and the need of catalyst and also reduces environmental problems caused by landfill accumulation. PMID- 29573887 TI - Artifacts in Shear Wave Elastography Images of Thyroid Nodules. AB - The purpose of the study described here was to evaluate the presence and types of artifacts seen in color elastograms in thyroid elastography using shear wave elastography. This Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant study was approved by the ethics committee of our institution, and all patients provided written informed consent. One hundred seventy-eight patients (40 men and 138 women; mean age, 49 y; range, 19-84 y) were enrolled for a total of 241 thyroid nodules. After a short ultrasound (US) examination, SWE images were acquired at multiple levels in the nodule in transverse and longitudinal orientations. A total of 1297 images were obtained from 241 nodules for an average of 5.4 +/- 2.7 (mean +/- standard deviation) images per nodule. A retrospective review of all images was performed by one reviewer experienced in thyroid elastography. Two hundred eighty images (21.6%) were rated as good quality, and 112 (8.6%) were rated as moderate quality without artifacts. A total of 905 (69.8%) images had some artifact present, though most of these images (73.4%) were still interpretable. Two hundred forty-one images (18.6% of all images) were considered uninterpretable because of artifact. The most common types of artifacts were due to operator error (44.6% of all images), primarily compression (36.5% of all images). Other artifacts seen were due to anatomy (presence of carotid pulsation or adjacent to thyroid or location in isthmus, 11% of all images), nodule characteristics (cystic and calcified nodules or large nodules with lack of penetration, 17% of all images) and other artifacts that could not be explained by the prior mentioned causes (13% of all images). Our study indicates that artifacts are common in elastography images. Operator error was the most common type of artifact we saw. This should be easily correctable by adequate knowledge and recognition with subsequent correction of the artifacts. PMID- 29573888 TI - Effects of Low-Intensity Pulsed Ultrasound for Preventing Joint Stiffness in Immobilized Knee Model in Rats. AB - The purpose of this study was to examine the effect of low-intensity pulsed ultrasound (LIPUS) in preventing joint stiffness. Unilateral knee joints were immobilized in two groups of rats (n = 6/period/group). Under general anesthesia, the immobilized knee joints were exposed to LIPUS for 20 min/d, 5 d/wk, using an existing LIPUS device (LIPUS group, 1.5-MHz frequency, 1.0-kHz repetition cycle, 200-us burst width and 30-mW/cm2 power output) until endpoints (2, 4 or 6 wk). In the control group, general anesthesia alone was administered in the same manner as in the other group. The variables compared between the groups included joint angles; histologic, histomorphometric and immunohistochemical analyses; quantitative reverse transcription polymerase chain reactions; and tissue elasticity. LIPUS had a preventive effect on joint stiffness, resulting in decreased adhesion, fibrosis and inflammation and hypoxic response after joint immobilization. PMID- 29573889 TI - Effects of long-term consumption of broccoli sprouts on inflammatory markers in overweight subjects. AB - BACKGROUND & AIMS: Broccoli sprouts represent an interesting choice of healthy food product as they are rich in glucosinolates and their cognate bioactive metabolites, isothiocyanates able to counteract the negative effects of diverse pathologies. As obesity is linked to an inflammatory component, the aim of the study was to evaluate the anti-inflammatory action of broccoli sprouts in overweight adult subjects. METHODS: An in vivo controlled study was performed in 40 healthy overweight subjects (ClinicalTrials.gov ID NCT 03390855). Treatment phase consisted on the consumption of broccoli sprouts (30 g/day) during 10 weeks and the follow-up phase of 10 weeks of normal diet without consumption of these broccoli sprouts. Anthropometric parameters as body fat mass, body weight, and BMI were determined. Inflammation status was assessed by measuring levels of TNF alpha, IL-6, IL-1beta and C-reactive protein. RESULTS: IL-6 levels significantly decreased (mean values from 4.76 pg/mL to 2.11 pg/mL with 70 days of broccoli consumption, p < 0.001) and during control phase the inflammatory levels were maintained at low grade (mean values from 1.20 pg/mL to 2.66 pg/mL, p < 0.001). C reactive protein significantly decreased as well. CONCLUSIONS: This study represents an advance in intervention studies as the broccoli sprouts were included in a daily dietary pattern in quantities that reflect a real consumption. Further studies are necessary to elucidate the role of this healthy rich and nutritious food product, but these promising results support the current evidence on the healthy properties of Brassica varieties.

PMID- 29573891 TI - Adolescents' perceptions of flavored tobacco products, including E-cigarettes: A qualitative study to inform FDA tobacco education efforts through videogames. AB - INTRODUCTION: Flavored tobacco products have been shown to appeal to youth, however tobacco control strategies have traditionally not focused on these products. To inform the adaptation of an existing videogame to focus on the prevention of flavored tobacco product use, this study explored adolescents' perceptions, beliefs, and social norms surrounding these products, including flavored e-cigarettes. METHODS: We conducted and analyzed transcripts from seven focus groups with 11-17-year-old adolescents (n = 33) from after-school programs in CT and CA in 2016. Participants discussed flavored tobacco product beliefs and experiences, and how these compared to traditional cigarettes. RESULTS: Thematic analysis of transcripts revealed that participants could name flavors in tobacco products, even though few discussed first-hand experience with the products. Most groups perceived that flavored tobacco product and flavored e-cigarette use facilitated peer approval and acceptance. All groups discussed how youth could easily access flavored tobacco products, including e-cigarettes. Flavoring was a salient aspect of e-cigarette advertisements; however the groups did not recall exposure to other types of flavored tobacco product counter-marketing. CONCLUSIONS: These data can help inform the development of tobacco control strategies, novel interventions (such as videogames), and future FDA efforts to prevent adolescent tobacco product use through education and risk communication. PMID- 29573892 TI - Creating a conceptual model for family caregivers of older adults intervention research: A narrative review of learned resourcefulness, resourcefulness, and the transtheoretical model. AB - Providing and maintaining optimal care is challenging for older family caregivers who are caring for disabled older adults. Learned Resourcefulness can facilitate family caregivers' self-help strategies, and Resourcefulness can facilitate help seeking from others. However, little is known about how older family caregivers can effectively maintain and adapt self-help and help-seeking strategies over time, especially as the dynamic nature of caregiving for disabled older adults demands change. To this end, the Transtheoretical model (TTM) provides useful constructs that address family caregivers' readiness to change their self-help and help-seeking behaviors. This paper reviews relevant literature regarding Learned Resourcefulness, Resourcefulness, and the TTM. The proposed conceptual model incorporates constructs from the TTM integrated with Learned Resourcefulness and Resourcefulness strategies to aid in the development and testing of interventions that are designed to promote the quality of life and health of older family caregivers while they are providing care to disabled older adults. PMID- 29573893 TI - Health care providers' perceptions of family caregivers' involvement in consultations within a geriatric hospital setting. AB - This study explored health professionals' (HPs') experiences of interacting with family care-givers (FCs), and the strategies they employ during these interactions. Qualitative methods involved audio-taped and transcribed in-depth semi-structured interviews with 21 HPs (doctors, nurses) from the geriatric wards of two tertiary hospitals. Framework methods were used to analyze data. Seven main themes emerged: Variation in family behaviours; FCs face many challenges; Psychosocial factors influence FCs' behaviours; Attitudes, competing responsibilities and lack of resources influencing HPs' strategies and behaviours; Strategies employed by HPs to improve communication; HPs' self-care strategies; Impact of interactions on HPs and the healthcare system. Inter relationships between the themes were then integrated into a three-part model. This study offered insights into HPs' perspectives, experiences, and behaviours in geriatric consultations where FCs are present. Findings emphasised the need for HP training programs to improve communication and collaboration between HPs, patients, and FCs. PMID- 29573894 TI - The Effectiveness of Mini-C-Arm Fluoroscopy for the Closed Reduction of Distal Radius Fractures in Adults: A Randomized Controlled Trial. AB - PURPOSE: Most distal radius (DR) fractures are initially managed with closed reduction and orthosis application. Mini-C-arm fluoroscopy provides assessment of reduction quality in real time. Our null hypothesis was that there would be no difference in the reduction quality of DR fractures in the emergency department when using mini-C-arm fluoroscopy during reduction compared with standard reduction techniques (evaluating reduction quality with orthogonal radiographs taken in an orthosis). METHODS: Sixty-three consecutive patients with closed DR fractures requiring reduction between April 2015 and April 2017 were prospectively randomized to standard versus fluoroscopically aided reductions. Reductions were performed by orthopedic surgery residents. The primary outcome measurement was reduction quality (radial height, radial inclination, ulnar variance, and volar tilt) as measured on postreduction radiographs. RESULTS: Standard reductions were performed in 34 patients and fluoroscopically aided reductions in 29 patients. The 2 groups were similar in regards to all potential confounders that were analyzed. No differences in postreduction radial height, radial inclination, ulnar variance, or volar tilt were noted. Overall reduction attempts and subjective difficulty of fracture reduction were increased when using fluoroscopy. The rate of initial operative management did not differ between groups. CONCLUSIONS: The use of mini-C-arm fluoroscopy during the initial closed reduction of adult DR fractures results in equivalent postreduction radiographic parameters when compared with conventional reduction techniques. Additional research regarding time spent in the emergency department and overall cost could elucidate potential benefits of fluoroscopically aided DR fracture reduction. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I. PMID- 29573895 TI - The Effect of Dorsally Angulated Distal Radius Deformities on Carpal Kinematics: An In Vitro Biomechanical Study. AB - PURPOSE: The purpose was to quantify the effect of distal radius dorsal angulation (DA) on carpal kinematics and the relative roles of the radiocarpal and midcarpal joints during wrist motion. METHODS: Six cadaveric specimens (69 +/ 17 y) were mounted at 90 degrees elbow flexion in a custom wrist motion simulator. The wrist was guided through planar passive flexion and extension motion trials (~ 5 degrees /s). A custom modular distal radius implant was used to simulate native alignment and 3 distal radius DA deformities (10 degrees , 20 degrees , 30 degrees ). An optical tracking system captured carpal bone motion, from which radiocarpal and midcarpal joint motion was determined. RESULTS: The radiocarpal joint made a greater contribution to wrist motion than the midcarpal joint in flexion, and the midcarpal joint made a greater contribution to motion than the radiocarpal joint in wrist extension. Increasing DA caused the radiocarpal joint contribution to increase throughout the motion arc, with the effect being more pronounced in wrist flexion. Conversely, as DA increased, the midcarpal joint contributed less rotation to the total wrist motion and its overall motion arc decreased; the magnitude of effect was greater in wrist extension. Dorsal angulation resulted in increased lunate flexion with respect to the distal radius. CONCLUSIONS: Our findings agree with current literature that suggests that, in an uninjured wrist, the radiocarpal joint predominates flexion, and the midcarpal joint predominates extension. In addition, the radiocarpal joint has an amplified contribution in wrist flexion with greater DA malunion. CLINICAL RELEVANCE: The altered contributions of the radiocarpal and midcarpal joints may contribute to pain, stiffness, and the development of arthritis, which is commonly seen at the radiocarpal joint after malunion of the distal radius. PMID- 29573896 TI - Kienbock Disease in the Skeletally Immature Patient. AB - Kienbock disease is uncommon in skeletally immature patients. Although there is no gold standard treatment for Kienbock disease in the skeletally immature patient, surgical and nonsurgical treatment options have been shown to be effective. Initial immobilization with a cast, protection with an orthosis, and avoidance of repetitive forceful activities have been shown to be effective in some cases. Surgery may be offered to the skeletally immature patient when nonsurgical treatment is ineffective. Among several surgical techniques used for treatment in the skeletally immature patient with Kienbock disease, distal radial osteotomies have been the most frequently performed surgery; however, radial overgrowth is a concern. There is a great potential for revascularization and remodeling of the lunate in the skeletally immature patients with Kienbock disease. Good and excellent clinical and radiological outcomes can be achieved with both nonsurgical and surgical treatments. PMID- 29573897 TI - Documenting Combined Congenital Upper Limb Anomalies Using the Oberg, Manske, and Tonkin Classification: Implications for Epidemiological Research and Outcome Comparisons. AB - PURPOSE: Congenital upper limb anomalies (CULAs) exhibit a wide spectrum of phenotypic manifestations. To help the clinician evaluating this variety of CULAs, the Oberg, Manske, and Tonkin (OMT) classification was recently introduced. The OMT classification allows for documentation of combined hand anomalies. However, subsequent epidemiological and validation studies using the OMT scheme commonly registered only the main anomaly per arm. This study illustrates both the deficits of single diagnosis documentation as well as the merits of registering every anomaly for epidemiological research, outcome comparison, and overall applicability of the classification. METHODS: We retrospectively reviewed patients visiting the Erasmus MC - Sophia Children's Hospital between 2012 and 2014. All congenital anomalies of both limbs were classified according to the OMT scheme. The frequency of combined diagnoses as well as recurrent combinations were analyzed. The relation to the coregistered syndromes was studied. RESULTS: We included 746 patients, 79.5% of whom could be documented with a single OMT diagnosis. In 20.5%, a combination of OMT diagnoses was documented. We documented 149 different combinations: 102 were documented once, 47 were documented repeatedly (n = 196); for example, in patients with Greig syndrome. The prevalence of this syndrome was significantly higher in patients with a combination of radial polydactyly, ulnar polydactyly, and/or syndactyly (2.9% vs 33.3% and 60% in patients with 1 vs 2 and 3 diagnoses). CONCLUSIONS: Documentation of combined OMT diagnoses is required in a fifth of the patients. Not doing so will cause loss of phenotypic information and can hamper outcome comparison and epidemiological research. Documentation of combined OMT diagnoses can help to identify subgroups within a population, for example, patients with an underlying syndrome. Last, combined documentation of diagnoses improves flexibility of the classification and thereby better allows universal application. CLINICAL RELEVANCE: Consensus on the application of the OMT classification is critical to achieving the universal adoption of the system by hand surgeons and other medical professionals. PMID- 29573898 TI - Efficacy of prehospital administration of tranexamic acid in trauma patients: A meta-analysis of the randomized controlled trials. AB - OBJECTIVE: Antifibrinolytic agent tranexamic acid (TXA) has a potential clinical benefit for in-hospital patients with severe bleeding but its effectiveness in pre-hospital settings remains unclear. We conducted a systematic review and meta analysis to evaluate whether pre-hospital administration of TXA compared to placebo improve patients' outcomes? METHODS: PubMed, MEDLINE, Cochrane Library, WHO International Clinical Trials Registry Platform, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, clinicaltrials.gov and Google scholar databases were searched for a retrospective, prospective and randomized (RCT) or quasi-RCT studies that assessed the effect of prehospital administration of TXA versus placebo on the outcomes of trauma patients with significant hemorrhage. The main outcomes of interest were 24hour 30-day mortality and in-hospital thromboembolic complications. Two authors independently abstracted the data using a data collection form. Results from different studies were pooled for the analysis, when appropriate. RESULTS: Out of 92 references identified through the search, two analytical studies met the inclusion criteria. The effect of TXA on 24-hour mortality had a pooled odds ratio (OR) of 0.49 (95% CI 0.28-0.85), 30-day mortality OR of 0.86 (95% CI, 0.56-1.32), and thromboembolic events OR of 0.74 (95% CI, 0.27-2.07). CONCLUSION: Prehospital TXA appears to reduce early mortality in trauma patients. The pooled analysis also shows a trend toward lower 30-day mortality and reduced risk of thromboembolic events. Additional randomized controlled clinical trials are needed to determine the significance of these trends. PMID- 29573899 TI - National characteristics of Emergency Department visits by patients with cancer in the United States. AB - PURPOSE: The Emergency Department (ED) is an important venue for the care of patients with cancer. We sought to describe the national characteristics of ED visits by patients with cancer in the United States. METHODS: We performed an analysis of 2012-2014 ED visit data from the National Hospital Ambulatory Medical Care Survey (NHAMCS). We included adult (age>=18years) ED patients, stratified by history of cancer. Using the NHAMCS survey design and weighting variables, we estimated the annual number of adult ED visits by patients with cancer. We compared demographics, clinical characteristics, ED resource utilization, and disposition of cancer vs. non-cancer patients. RESULTS: There were an estimated 104,836,398 annual ED visits. Patients with cancer accounted for an estimated 3,879,665 (95% CI: 3,416,435-4,342,895) annual ED visits. Compared with other ED patients, those with cancer were older (mean 64.8 vs. 45.4years), more likely to arrive by Emergency Medical Services (28.0 vs. 16.9%), and experienced longer lengths of ED stay (mean 4.9 vs. 3.8h). Over 65% of ED patients with cancer underwent radiologic imaging. Patients with cancer almost twice as likely to undergo CT scanning; four times more likely to present with sepsis; twice as likely to present with thrombosis, and three times more likely to be admitted to the hospital than non-cancer patients. CONCLUSIONS: Patients with cancer comprise nearly 4 million ED visits annually. The findings highlight the important role of the ED in cancer care and need for addressing acute care conditions in patients with cancer. PMID- 29573900 TI - Usefulness of optic nerve ultrasound to predict clinical progression in multiple sclerosis. AB - INTRODUCTION: Progressive neuronal and axonal loss are considered the main causes of disability in patients with multiple sclerosis (MS). The disease frequently involves the visual system; the accessibility of the system for several functional and structural tests has made it a model for the in vivo study of MS pathogenesis. Orbital ultrasound is a non-invasive technique that enables various structures of the orbit, including the optic nerve, to be evaluated in real time. MATERIAL AND METHODS: We conducted an observational, ambispective study of MS patients. Disease progression data were collected. Orbital ultrasound was performed on all patients, with power set according to the 'as low as reasonably achievable' (ALARA) principle. Optical coherence tomography (OCT) data were also collected for those patients who underwent the procedure. Statistical analysis was conducted using SPSS version 22.0. RESULTS: Disease progression was significantly correlated with ultrasound findings (P=.041 for the right eye and P=.037 for the left eye) and with Expanded Disability Status Scale (EDSS) score at the end of the follow-up period (P=.07 for the right eye and P=.043 for the left eye). No statistically significant differences were found with relation to relapses or other clinical variables. DISCUSSION: Ultrasound measurement of optic nerve diameter constitutes a useful, predictive factor for the evaluation of patients with MS. Smaller diameters are associated with poor clinical progression and greater disability (measured by EDSS).

PMID- 29573902 TI - Computed tomography underestimates rotator cuff pathology in patients with glenohumeral osteoarthritis. AB - BACKGROUND: Computed tomography (CT) is the standard assessment of glenoid morphology before shoulder arthroplasty and is commonly used to evaluate rotator cuff pathology in patients with glenohumeral osteoarthritis (GHOA). Magnetic resonance imaging (MRI) is not routinely used in this setting but has higher sensitivity in diagnosing full-thickness rotator cuff tears (RCT) and is considered the gold standard. The purpose of this study was to determine the sensitivity and specificity of CT in diagnosing full-thickness RCTs and compare the evaluation of fatty infiltration and muscle atrophy on CT vs. MRI in the setting of GHOA. METHODS: In this retrospective case-controlled study, we identified 49 patients from a prospectively maintained 2-surgeon registry who received preoperative CT and MRI scans for the evaluation of GHOA between 2011 and 2016. Three fellowship-trained shoulder surgeons assessed rotator cuff integrity, fatty infiltration, and muscle atrophy in the CT and MRI scans. RESULTS: CT sensitivity and specificity were 20% and 95.5%, respectively. Fatty infiltration was significantly lower on CT for the supraspinatus (P = .003), infraspinatus (P < .001), and subscapularis (P = .0182), whereas muscle atrophy was significantly lower on CT for only the supraspinatus (P = .0023). CONCLUSIONS: Our results suggest that CT underestimates the frequency of full thickness RCTs and the severity of fatty infiltration and muscle atrophy in the setting of GHOA before total shoulder arthroplasty. PMID- 29573904 TI - Causes of Emergency Department Overcrowding and Blockage of Access to Critical Services in Beijing: A 2-Year Study. AB - BACKGROUND: Emergency department (ED) overcrowding is a serious issue worldwide. OBJECTIVES: This study was done to evaluate the degree of overcrowding in local "teaching hospitals" in Beijing, and to ascertain the apparent root causes for the pervasive degree of overcrowding in these EDs. METHODS: This is a multicenter cross-sectional study. The studied population included all ED patients from 18 metropolitan teaching hospital EDs in Beijing for calendar years 2013 and 2014. Patient characteristics, and the primary reasons that these patients sought care in these EDs, are described. RESULTS: The total numbers of annual emergency visits were 1,554,387 and 1,615,571 in 2013 and 2014, respectively. High acuity cases accounted for 4.6% and 5.5% of the total annual emergency visits in 2013 and 2014, respectively. The percentage of patients placed into "Observation" beds, which were created to accommodate patients deemed to have problems too complex to be treated in an inpatient bed, or to accommodate patients simply needing chronic care, was 11.9% and 13.1% in 2013 and 2014, respectively. The ED boarded patients accounted for 2.71% and 2.6% of the total annual emergency visits in 2013 and 2014, respectively. The average waiting time to admit the ED boarded patients was 37.1 h and 36.2 h in 2013 and 2014, respectively. Respiratory symptoms were the most common presenting complaints, and an upper respiratory infection was the most common ED diagnosis. Patients who had pneumonia or various manifestations of end-stage diseases, such as advanced dementia or multiple organ dysfunction, were the most common characteristics of patients who had stays in "Observation" units. CONCLUSIONS: One principal reason for ED crowding in Beijing lies in the large numbers of patients who persist in the expectation of receiving ongoing care in the ED for minor illnesses. However, as is true in many nations, one of the other most important root causes of ED crowding is "access block," the inability to promptly move patients deemed by emergency physicians to need inpatient care to an inpatient bed for that care. However, in our system, another challenge, not widely described as a contributor to crowding in other nations, is that doctors assigned to inpatient services have been empowered to refuse to admit patients perceived to have overly "complex" needs. Further, patients with multisystem illnesses or end-stage status, who need ongoing chronic care to manage activities of daily living, have begun to populate Beijing EDs in increasing numbers. This is an issue with various root causes. PMID- 29573905 TI - Autoimmune hemolytic anemia (AIHA) following allogeneic hematopoietic stem cell transplantation (HSCT): A retrospective analysis and a proposal of treatment on behalf of the Grupo Espanol De Trasplante de Medula Osea en Ninos (GETMON) and the Grupo Espanol de Trasplante Hematopoyetico (GETH). AB - Autoimmune hemolytic anemia (AIHA) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT) associated with poor outcome. However, an optimal therapeutic approach is lacking. Between 2000 and 2015, 4099 allogeneic HSCT were performed in eight pediatric centers of the Grupo Espanol De Trasplante de Medula Osea en Ninos (GETMON) and six adult centers of the Grupo Espanol de Trasplante Hematopoyetico (GETH). Sixty cases of AIHA were registered with a cumulative incidence of 1.5% occurring at a median of 6 months after HSCT. Patients aged less than 15 years (P=.005), and patients using cord blood (P=.005) or an HLA mismatch donor (P=.005) were more likely to develop AIHA. Most patients were lymphopenic at the time of diagnosis of AIHA, including a low number of regulatory T lymphocytes (median 3/MUL). Median lines of treatment received for AIHA was 3 (range, 1-7). Almost all patients received corticosteroids (88%) and more than half received immunoglobulins or rituximab (63% and 67%, respectively). Complete resolution of AIHA was achieved in 33 of 60 cases (55%). Cumulative incidence of AIHA-related mortality was 17+/-6%. We found a correlation of AIHA outcome with age (better outcome in younger than 15 years, RR=1.87, P=.01) and rituximab response (higher rate of complete remission in patients responding to rituximab, RR=1.72, P=.025). We analyzed the factors involved in the response to rituximab and found a better response when there was ABO donor/receptor disparity (P=.014) and in those patients with B lymphocytes count above the median (38/MUL) (P=.05).Thirty-six of 60 patients survived yielding a disease free survival of 52+/-8% at 40 months. In Cox analysis, age (children vs adults, HR: 8.19, CI 95%: 2.39-28.12, P=.001) and AIHA outcome (complete remission vs partial remission/non response, HR: 4.18, CI 95%: 1.55-11.22, P=.005) were associated with a better survival. Our data suggest that patients who developed AIHA after HSCT are severely lymphopenic and have a high risk of mortality. Outcome is better in children and in patients treated with rituximab. We also propose an algorithm for treatment of AIHA after HSCT. PMID- 29573906 TI - Reply to DR. De Cassai et al.

AB - Up to 40% of patients treated for rectal cancer suffer from therapy-related symptoms. Innervation injury is one of the suggested pathomechanisms of those symptoms hence the development of a valid, non-invasive tool for the assessment of neural systems is crucial. The aim of this work is to study the fractal properties of the surface electromyography signals obtained from patients suffering from rectal cancer. The anal sphincter activity was investigated for the group of 15 patients who underwent surgical treatment. Multifractal detrended fluctuation analysis was implemented to analyze the data, obtained at four different stages: one before treatment and three times after the surgery. The results from the standard detrended fluctuation analysis and empirical mode decomposition methods are presented and compared. The statistically significant differences between the stages of treatment were identified for the selected spectral parameters: width and maximum of the spectrum. PMID- 29573910 TI - Synthesis and investigations into the anticancer and antibacterial activity studies of beta-carboline chalcones and their bromide salts. AB - A series of sixteen beta-carbolines, bearing chalcone moiety at C-1 position, were prepared from easily accessible 1-acetyl-beta-carboline and various aldehydes under basic conditions followed by N2-alkylation using different alkyl bromides. The prepared compounds were evaluated for in vitro cytotoxicity against a panel of human tumor cell lines. N2-Alkylated-beta-carboline chalcones 13a-i represented the interesting anticancer activities compared to N2-unsubstituted beta-carboline chalcones 12a-g. Off the prepared beta-carbolines, 13g exhibited broad spectrum of activity with IC50 values lower than 22.5 uM against all the tested cancer cell lines. Further, the N2-alkylated-beta-carboline chalcone 13g markedly induced cell death in MDA-MB-231 cells by AO/EB staining assay. The most cytotoxic compound 13g possessed a relatively high drug score of 0.48. Additionally, the prepared beta-carboline chalcones displayed moderate antibacterial activities against tested bacterial strains. PMID- 29573912 TI - Trends in Periprosthetic Hip Infection and Associated Costs: A Population-Based Study Assessing the Impact of Hospital Factors Using National Data. AB - BACKGROUND: Periprosthetic joint infection (PJI) is an important cost driver in hip arthroplasty revisions, thus necessitating careful trend monitoring. Recent national trend data are lacking; we therefore assessed national PJI burden, trends in prevalence, and hospitalization costs. METHODS: We extracted data on hip arthroplasty revisions from the National Inpatient Sample (2003-2013; n = 465,209). Trends in PJI prevalence and hospitalization costs were (1) assessed for the full cohort and (2) stratified by hospital teaching status, hospital bed size (<=299, 300-499, and >=500 beds), and hospital region (Northeast, Midwest, South, and West). The Cochran-Armitage trend test (PJI prevalence) and linear regression (hospitalization costs) determined significance of trends. Trends were adjusted for patient's age, gender, insurance type, race, Deyo-Charlson comorbidities, obesity, length of stay, and hospital characteristics. RESULTS: Overall, PJI prevalence was 15.0% (n = 70,011); adjusted prevalence increased from 13.1% in 2003 to 16.4% in 2013 (P < .0001), while adjusted median PJI hospitalization costs increased from $28,240 in 2003 to $31,529 in 2013 (P < .0001). Rural hospitals had the lowest PJI burden (12.5%; n = 4,525), while urban and teaching hospitals had the highest PJI burden (16.4%; n = 40,297). The stratified analyses, particularly in large hospitals (>500 beds), showed that PJI prevalence increased from 13.0% (2003) to 17.4% (2013; a 33.8% increase; P < .0001). Similarly, PJI revision hospitalization costs increased from a median of $27,490 (2003) to $31,312 (2013; a 14% increase; P < .0001). CONCLUSION: The burden of PJI in hip arthroplasty revision is increasing and-while additional research is needed-there appears to be a particular shift of revision burden to larger hospitals with increasing costs. PMID- 29573911 TI - Limonene promotes osteoblast differentiation and 2-deoxy-d-glucose uptake through p38MAPK and Akt signaling pathways in C2C12 skeletal muscle cells. AB - BACKGROUND: Limonene is a cyclic monoterpene (CTL) found in citrus fruits and many plant kingdoms. It has attracted attention as potential molecule due to its diverse biological activities. However, molecular mechanism involved in the osteogenic induction of CTL in C2C12 skeletal muscle cells remain unclear. PURPOSE: Skeletal development maintains the bone homeostasis through bone remodeling process. It coordinated between the osteoblast and osteoblast process. Osteoporosis is one of the most common bone diseases caused by a systemic reduction in bone mass. Recent osteoporosis treatment is based on the use of anti resorptive and bone forming drugs. However, long term use of these drugs is associated with serious side effects and strategies on the discovery of lead compounds from natural products for osteoblast differentiation are urgently needed. Therefore, we planned to find out the role of CTL on osteoblast differentiation and glucose uptake in C2C12 cells and its effect on signaling pathways. METHODS: Cell proliferation, alkaline phosphatase (ALP) activity, calcium deposition, genes, and proteins associated with osteoblast activation and glucose utilization were analysed. RESULTS: CTL did not affect the cell viability. CTL significantly increased ALP activity, calcium depositions and the expression of osteogenic specific genes such as Myogenin, Myogenic differentiation 1 (MyoD), ALP, Run-related transcription factor 2(RUNX2), osteocalcin (OCN). In addition, CTL induced the mRNA expression of bone morphogenetic proteins (BMP-2 BMP-4 BMP-6 BMP-7 BMP-9). CTL treatment enhanced 2 Deoxy-d-glucose (2DG) uptake. Moreover, CTL stimulated the activation of p38 mitogen activated protein kinase (p38MAPK), Protein kinase B (Akt), Extracellular signal related kinase (ERKs) by increasing phosphorylation. CTL treatment abolished p38 inhibitor (SB203580) mediated inhibition of osteoblast differentiation, but no effect was noted by ERKs specific inhibitor (PD98059). CONCLUSION: These results suggest that limonene induces osteoblast differentiation and glucose uptake through activating p38MAPK and Akt signaling pathways, confirming the molecular basis of the osteoblast differentiation by limonene in C2C12 skeletal muscle cells.

AB - BACKGROUND: Controversy remains over the surgical management of large osteochondral lesions of the femoral head in young, active patients. The purpose of this study is to assess midterm clinical and radiographic outcomes after fresh osteochondral allograft transplantation (OAT) for large femoral head lesions at minimum 2-year follow-up. METHODS: A retrospective review of prospectively collected data was performed for 22 patients under the age of 50 years with defined femoral head osteochondral lesions who underwent fresh OAT between 2008 and 2015. Patients were assessed clinically using the modified Harris Hip Score (mHHS) preoperatively and at each follow-up visit. Postoperative radiographs were evaluated for graft integrity and Kellgren & Lawrence Grade for osteoarthritis severity. Complications and reoperation were assessed by chart review. Kaplan Meier survivorship analyses with 95% confidence intervals were performed for the end point of conversion to total hip arthroplasty. RESULTS: At a mean follow-up of 68.8 months (26-113), the mean mHHS improved significantly (P < .001) from 48.9 (19-84) to 77.4 (35-98). Sixteen of 22 patients (72.7%) had an mHHS >=70 at the latest follow-up. Arthritic progression, as indicated by an increase in the Kellgren & Lawrence Grade, occurred in 4 of 22 hips (18.2%). Five patients (22.7%) underwent conversion to total hip arthroplasty. Graft survivorship was 86.4 +/- 7.3% at 2 years, 78.5 +/- 10.0% at 5 years, and 67.3 +/- 13.5% at 9 years. CONCLUSION: Fresh OAT may be a viable treatment option for osteochondral defects of the femoral head in young, active patients with minimal preexisting joint deformity. PMID- 29573914 TI - Prior High Tibial Osteotomy Does Not Affect the Survival of Total Knee Arthroplasties: Results From the Danish Knee Arthroplasty Registry. AB - BACKGROUND: High tibial osteotomy (HTO) is a joint preserving treatment of unicompartmental osteoarthritis in the knee. In cases with insufficient or deteriorating clinical results patients may undergo a total knee arthroplasty (TKA). The influence of prior HTO on TKA survival is debated. METHODS: We conducted a population-based registry study comparing 1044 primary TKAs in patients with prior HTO to 63,763 de novo TKAs inserted from 1997 to 2015. Implant survival was estimated by Kaplan-Meier analysis with revision of any kind as endpoint. Patient and surgery characteristics, including choice of implant design, were compared and their influence on TKA survival was estimated by Cox regression. Finally, indications of revision were compared between the groups. RESULTS: TKA following HTO had an inferior survival with a 10-year estimated survival of 91% compared to 94% for de novo TKA, corresponding to a crude hazard ratio (HR) of 1.73 (P < .001). However, after adjustment for differences in gender and age this risk diminished (HR 1.19, P = .09). The choice of implant constraint was similar between the groups and in both groups posterior stabilized TKA was associated with inferior survival with an adjusted HR of 1.46 (P = .03) in post-HTO TKA when compared to cruciate-retaining TKA. CONCLUSION: TKA following HTO had a crude inferior survival when compared to TKA without prior surgery of any kind. The inferior survival was explainable by patient characteristics, defined by male gender and lower age, rather than the prior HTO. However, when the prior HTO resulted in the use of posterior stabilized TKA the survival decreased.

AB - BACKGROUND: Yoga is growing in popularity as a form of exercise throughout the world. Orthopedic patients participate in yoga, yet little is known about the ranges-of-motion of the hip within various yoga poses. Orthopedic surgeons are unsure about what potential positions their patients are placing their hips during a yoga practice. The aim of this study is to quantify the degree of hip motion with common yoga poses. METHODS: Twenty healthy, regular practitioners of yoga performed 11 different yoga poses in a standardized fashion. Motion analysis was used to capture range-of-motion of the hip during each pose. RESULTS: Many yoga poses put the hip in extremes of motion. Poses such as downward dog, forward fold, seated twist, and pigeon stressed the hip in flexion. Warrior 1, warrior 2, crescent lunge, pigeon, and triangle stressed the hip in extension. Eagle and seated twist put the hip in higher adduction, while half moon, eagle, and triangle produced more hip internal rotation. CONCLUSION: Many poses were found to reach extremes of hip motion. This study may help guide the orthopedic surgeon in counseling hip arthroplasty and hip impingement patients about yoga-related activity. By knowing which poses potentially stress the hip in particular planes of motion, surgeons may better inform their patients who are returning to yoga after injury or surgery. PMID- 29573917 TI - Is There an Association Between Smoking Status and Prosthetic Joint Infection After Primary Total Joint Arthroplasty? AB - BACKGROUND: Recent reports highlighted the association between smoking and higher risk of postsurgical infections. The aim was to compare the incidence of prosthetic joint infection after primary total joint arthroplasty (TJA) according to smoking status. METHODS: A prospective hospital registry-based cohort study was performed including all primary knee and hip TJAs performed between March 1996 and December 2013. Smoking status preoperatively was classified into never, former, and current smoker. Incidence rates and hazard ratios (HRs) for prosthetic joint infection according to smoking status were assessed within the first year and beyond. RESULTS: We included 8559 primary TJAs (mean age 69.5 years), and median follow-up was 67 months. There were 5722 never, 1315 former, and 1522 current smokers. Incidence rates of infection within the first year for never, former, and current smokers were, respectively, 4.7, 10.1, and 10.9 cases/1000 person-years, comparing ever vs never smokers, crude and adjusted HRs were 2.35 (95% confidence interval [CI] 1.39-3.98) and 1.8 (95% CI 1.04-3.2). Beyond the first year, crude and adjusted HRs were 1.37 (95% CI 0.78-2.39) and 1.12 (95% CI 0.61-2.04). CONCLUSION: Smoking increased the infection risk about 1.8 times after primary hip or knee TJA in both current and former smokers. Beyond the first year, the infection risk was similar to never smokers. PMID- 29573918 TI - Minimum 10-Year Outcome of One-Stage Total Hip Arthroplasty Without Subtrochanteric Osteotomy Using a Cementless Custom Stem for Crowe III and IV Hip Dislocation. AB - BACKGROUND: Options for total hip arthroplasty (THA) in high dislocated hips include subtrochanteric osteotomy (STO), high hip center positioning, and 2-stage surgery with progressive lowering using an external fixator before THA. We described the long-term results of 1-stage THA performed without STO, using a cementless customized stem associated if necessary with sequential tenotomies and/or greater trochanteric osteotomy. METHODS: Ninety-eight consecutive THA without STO were performed using this technique. Of those 98 hips, 26 hips with high dislocation (12 class III and 14 class IV according to the Crowe classification) were evaluated at an average follow-up of 16 (10-22) years. RESULTS: At the time of last follow-up, the mean Harris Hip Score was 86 points (37-100). The mean leg-length discrepancy was 7 +/- 5 mm (0-17). Two transient (7.7%) nerve palsies (1 sciatic and 1 femoral) were notified. A revision was required for 6 hips (23.1%). Kaplan-Meier survivorship analysis at 15 years regarding aseptic loosening of the femoral component was 87.5% (95% confidence interval, 76.5-99.1). During the same period, acetabular implant survivorship free from revision for aseptic loosening was 96.1% (95% confidence interval, 92.7 99.9). CONCLUSION: The combination of intramedullary fit and extramedullary adaptation for offset and anteversion provided by the custom stem can avoid additional procedures associated to THA in high developmental dysplasia of the hip. The clinical function and long-term survival reported in this series is encouraging for THA performed in case of high hip dislocation. PMID- 29573919 TI - Deep Vein Thrombosis Prophylaxis: State of the Art. AB - The selection of a prophylaxis regimen to prevent symptomatic pulmonary embolism and deep vein thrombosis is a balance between efficacy and safety. The latest American Academy of Orthopaedic Surgeons guideline recommended that either chemoprophylaxis or mechanical prophylaxis be used after total joint arthroplasty but did not recommend specific agents. However, the latest evidence-based American College of Chest Physicians guideline recommended a variety of chemoprophylaxis and mechanical agents for a minimum of 10 to 14 days after total joint arthroplasty. Risk stratification is the key to the selection of the appropriate prophylaxis regimen for the individual patient, but the optimal risk stratification protocol still needs to be developed. PMID- 29573920 TI - Choices, Compromises, and Controversies in Total Knee and Total Hip Arthroplasty Modifiable Risk Factors: What You Need to Know. AB - BACKGROUND: Total joint arthroplasty has historically been very successful for most patients, yet some still incur a complication. In an era of value-based care, certain efforts need to be taken to optimize patients' risk profile before surgery to decrease the chances of readmission or surgical complication. METHODS: We reviewed 10 key medical conditions and lifestyle factors that surgeons should improve before pursuing total joint arthroplasty and provide a summary of the available literature to guide certain optimization thresholds. RESULTS: With careful attention to and the creation of a preoperative checklist, surgeons can identify key domains, including morbid obesity, malnutrition, diabetes, smoking, opioid use, poor dentition, cardiovascular disease, preoperative anemia, staphylococcus colonization, and psychological disorders and intervene based on an individual's areas of deficiencies. CONCLUSION: By following stringent protocols and rescheduling surgery until optimization has occurred, we can work to provide patients the best chance for a successful outcome with an elective hip or knee arthroplasty. PMID- 29573921 TI - The impact of daily bladder filling on small bowel dose for intensity modulated radiation therapy for cervical cancer. AB - Research demonstrates that instructing patients to have a full bladder for pelvic radiotherapy results in highly variable bladder volumes at daily treatment. We aimed to determine bladder volume variation in patients with intact cervical cancer treated with intensity-modulated radiotherapy (IMRT) on an empty bladder and estimate the difference in radiation dose to the small bowel compared to treating on a full bladder. We identified 29 patients treated with IMRT from 2010 to 2013 who underwent 2 planning computed tomography (CT) scans, 1 with a full bladder followed by 1 with an empty bladder. Interfractional variation in bladder volume was measured using 782 daily cone beam computed tomography (CBCT) scans. To estimate dose to small bowel, radiation plans were created on both empty and full bladder CT scans using an automated knowledge-based planning modeling program. Mean bladder volume with empty bladder instructions was 67 +/- 26 cc compared to 91 +/- 43 cc for no bladder instructions and 154 +/- 54 cc for full bladder instructions (p < 0.001). There was a significant reduction in the absolute bladder volume variation in patients given empty bladder instructions compared to full bladder instructions (p < 0.05) The intraclass correlation coefficient showed low reliability of bladder filling across all groups (p = 0.6). The average bowel V45 for the empty bladder plans was 188 cc, compared to 139 cc for the full bladder plans (p < 0.05). More plans created on an empty bladder exceeded Quantitative Analyses of Normal Tissue Effects in the Clinic (QUANTEC) guidelines but this was not significant (31% vs 14%, p = 0.12). Reliability of bladder volume at the time of radiation treatment is low, regardless of bladder filling instructions, although an empty bladder reduces absolute variation in bladder volume. Radiation planning on an empty bladder predicts a larger volume of small bowel receiving 45 Gy compared to a full bladder, although bowel dose on average is still within QUANTEC guidelines (V45 < 195 cc). PMID- 29573922 TI - Monaco treatment planning system tools and optimization processes. AB - The Monaco treatment planning system combines Monte Carlo dose calculation accuracy with robust optimization tools to provide high-quality radiotherapy treatment plans for three-dimensional conformal radiotherapy (3D CRT), intensity modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), stereotactic radiosurgery (SRS), and stereotactic body radiotherapy (SBRT). Recent technology advances have allowed for fast calculation speeds, which allow clinicians and patients to benefit from the accuracy of the Monte Carlo algorithm while reducing overall planning time. A collection of biological and physical dose-based planning tools and templates simplify the planning process and allow for consistent results across organizations. At the same time, multicriteria optimization (MCO) ensures critical organs are spared to the greatest possible degree while maintaining target coverage. Monaco encompasses a full suite of treatment modalities, including conventional radiotherapy and particle therapy, and is paving the way for real-time adaptive treatments with developments in magnetic resonance (MR)-guided radiation therapy. PMID- 29573923 TI - A comprehensive evaluation of angular range and separation on image quality, image registration, and imaging dose for cone beam computed tomography in radiotherapy. AB - We aimed to comprehensively evaluate the quality, dose, and registration of cone beam computed tomography (CBCT) images acquired with different angular range (theta) and angular separation (Deltatheta). Elekta XVI volumetric imaging system was used in this study. CBCT images of a Catphan 503 phantom were reconstructed with projections that were acquired under 17 * 8 different combinations of theta (200 degrees to 360 degrees ) and Deltatheta (0.27 degrees to 3.24 degrees ). The evaluation indices were contrast-to-noise ratio (CNR), spatial resolution (modulation transfer function [MTF50%]), uniformity, and registration accuracy. The weighted computed tomography dose index (CTDIw) of CTDI Head dosimetry phantom was measured for estimating radiation exposure. CNR changed little from theta = 200 degrees to 260 degrees , but increased by ~ 2.0 times from theta = 260 degrees to 360 degrees . CNR also increased by ~ 2.5 times from Deltatheta = 2.16 degrees to 0.27 degrees . MTF50% increased with Deltatheta being decreased, but had no dependence on theta. Image uniformity became better when theta was smaller or larger than 260 degrees , but there was no correlation with Deltatheta. Registration of the overall body had a maximum error of 0.3 mm. The error of low-contrast objects' registration could reach as much as 1.3 mm. CTDIw showed a linear dependence on theta and 1/Deltatheta. Although the imaging dose is reduced with theta being decreased or Deltatheta being increased, the image quality may be degraded. Accuracy of image registration of a rigid body can be achieved; however, low-contrast objects' registration using images with inferior quality will introduce unacceptable errors for clinical use. Further, the benefits and extra dose received by the patients should be balanced, and scan protocols with theta between 210 degrees and 260 degrees or Deltatheta smaller than 0.54 degrees should not be recommended.

AB - A disposal method for fly ash from a municipal solid waste incinerator (MSWI-FA) that involved a water washing pretreatment and co-processing in a cement kiln was tested. The mass flows of toxic heavy metals (HMs), including volatile HM (Hg), semi-volatile HMs (Pb, Cd, Tl, and As), and low-volatility HMs, and polychlorinated dibenzo-p-dioxin/polychlorinated dibenzofuran (PCDD/Fs) in the input, intermediate, and output materials were characterized. The flue gas Hg concentrations from tests 0, 1, and 2, fed with 0, 3.1, and 1.7 t/h of dried washed FA (DWFA), were 28.60, 61.95, and 35.40 MUg N m-3, respectively. Co processing of DWFA did not significantly affect the metal concentration in clinker as most of the major input metals, with the exception of Cd, Pb, and Sb (which came from DWFA), were from raw materials and coal. Co-processing of DWFA did not influence on the release of PCDD/Fs; baseline and co-processing values ranged from 0.022 to 0.039 ng-TEQ/N m3, and from 0.01 to 0.031 ng-TEQ/N m3, respectively. The total destruction efficiency for PCDD/Fs in MSWI fly was 82.6%. This technology seems to be an environmentally sound option for the disposal of MSWI-FA. PMID- 29573925 TI - Use of solid phosphorus fractionation data to evaluate phosphorus release from waste activated sludge. AB - Waste activated sludge (WAS) can become an important source of phosphorus (P). P speciation was examined under anaerobic conditions, with different pH (4, 6 and 8) and temperatures (10, 20 and 35 degrees C). Aqueous P was measured and an extraction protocol was used to find three solid phosphorus fractions. A pH of 4 and a temperature of 35 degrees C gave a maximum of 51% of total P solubilized in 22 days with 50% of total P solubilized in 7 days. Batch tests indicate that little pH depression is needed to release non-apatite inorganic P (including microbial polyphosphate), while a pH of 4 rather than 6 will release more apatite inorganic P, and that organic P is relatively more difficult to release from WAS. Fractionation analysis of P in WAS can aid in design of more efficient methods for P recovery from WAS.

AB - "Fossetto" landfill has been operating in the municipality of Monsummano Terme (Pistoia Province, Italy) since 1988; the authorized volume for landfilling is about 1,000,000 m3; at the moment the plant is being mainly used to dispose of mechanically and biologically treated residual municipal solid waste. Since September 2006, an in-situ reverse osmosis leachate treatment plant has been operating to treat leachate. The treated water is being discharged into a small nearby stream while the concentrated leachate is being recirculated back into the landfill body following Italian Regulations and an authorization from the local authority (Pistoia Province). This paper presents monitoring results on leachate generation rates and composition for the past fifteen years. A moderate increase of the concentration of some of the monitored parameters occurred (e.g. ammonium, chlorides) and a decrease for most heavy metals. The increase of concentrations for Cl- and NH4+ was more evident in the leachate coming from the wells closer to reinjection area. However, the change in leachate composition did not affect the quality of the effluent from the leachate treatment plant. The annual volume of the generated leachate increased significantly right after the recirculation started. PMID- 29573927 TI - Stressing the Cardiopulmonary Vascular System: The Role of Echocardiography. AB - The cardiopulmonary vascular system represents a key determinant of prognosis in several cardiorespiratory diseases. Although right heart catheterization is considered the gold standard for assessing pulmonary hemodynamics, a comprehensive noninvasive evaluation including left and right ventricular reserve and function and cardiopulmonary interactions remains highly attractive. Stress echocardiography is crucial in the evaluation of many cardiac conditions, typically coronary artery disease but also heart failure and valvular heart disease. In stress echocardiographic applications beyond coronary artery disease, the assessment of the cardiopulmonary vascular system is a cornerstone. The possibility of coupling the left and right ventricles with the pulmonary circuit during stress can provide significant insight into cardiopulmonary physiology in healthy and diseased subjects, can support the diagnosis of the etiology of pulmonary hypertension and other conditions, and can offer valuable prognostic information. In this state-of-the-art document, the topic of stress echocardiography applied to the cardiopulmonary vascular system is thoroughly addressed, from pathophysiology to different stress modalities and echocardiographic parameters, from clinical applications to limitations and future directions. PMID- 29573928 TI - Left-Sided Atrial Septal Pouch is a Risk Factor for Cryptogenic Stroke. AB - BACKGROUND: The atrial septal pouch is an anatomic variant of the interatrial septum. The morphology of the left-sided septal pouch (LSSP) may favor blood stasis and predispose to thromboembolic events. The aim of this study was to determine the association between LSSP presence and cryptogenic stroke. METHODS: A total of 126 consecutive patients with cryptogenic stroke and 137 age-matched control patients without stroke were analyzed retrospectively. The presence and dimensions of LSSPs were assessed using transesophageal echocardiography. RESULTS: LSSP was present in 55.6% of patients with cryptogenic stroke and in 40.9% of those without stroke (P = .02). In univariate analysis, patients with LSSP were more likely to have cryptogenic stroke (odds ratio, 1.81; 95% CI, 1.11 2.95; P = .02). After adjusting for other risk factors using multiple logistic regression, the presence of an LSSP was found to be associated with an increased risk for cryptogenic stroke (odds ratio, 2.02; 95% CI, 1.19-3.41; P = .01). There were no statistically significant differences in size of the LSSP between patients with and those without stroke (P > .05). CONCLUSIONS: There is an association between the presence of an LSSP and an increased risk for cryptogenic stroke. More attention should be paid to clinical evaluations of LSSPs. PMID- 29573929 TI - Standardized Goal-Directed Valsalva Maneuver for Assessment of Inducible Left Ventricular Outflow Tract Obstruction in Hypertrophic Cardiomyopathy. AB - BACKGROUND: The Valsalva maneuver is widely used to provoke left ventricular outflow tract obstruction in hypertrophic cardiomyopathy (HCM). Whereas early experiments used a standardized, goal-directed approach by maintaining an intraoral pressure >40 mm Hg for >10 sec, current practice depends on patients' understanding and effort. The aim of this study was to evaluate the clinical effectiveness of the goal-directed Valsalva maneuver (GDV) in HCM as a method to provoke left ventricular outflow tract obstruction. METHODS: In this prospective study, patients blew into a syringe barrel connected to a manometer with rubber tubing and maintained an intraoral pressure of >40 mm Hg for >10 sec (GDV). Using Doppler echocardiography, peak left ventricular outflow tract gradient (pLVOTG) was measured at rest and using the provocative maneuvers of the self-directed Valsalva maneuver (SDV), GDV, and exercise. RESULTS: A total of 52 patients were included. Mean pLVOTG with GDV was higher compared with SDV (48 vs 38 mm Hg, P = .001, n = 52) and was similar to exercise (GDV, 52 mm Hg; exercise, 58 mm Hg; P = .42; n = 43). Reclassification to obstructive HCM (pLVOTG >= 30 mm Hg) with GDV was significantly higher than with SDV (38% vs 16.6%, P = .016) and comparable with exercise (50%, P = .51). Reclassification to severe obstruction (pLVOTG >= 50 mm Hg) was higher with GDV compared with SDV (28.3% vs 13.5%, P = .045) and was similar to exercise (29.7%). Furthermore, GDV identified two patients with occult severe obstruction in isolation. CONCLUSIONS: GDV is an objective, practical, and effective physiologic method of provoking left ventricular outflow tract obstruction. It can significantly alter patient management by reclassifying disease severity and should be incorporated in the routine clinical evaluation of patients with HCM.

PMID- 29573931 TI - Acromioclavicular and Coracoclavicular Ligament Reconstruction for Acromioclavicular Joint Instability: A Systematic Review of Clinical and Radiographic Outcomes. AB - PURPOSE: To perform a systematic review of the available literature on clinical and radiographic outcomes after surgical treatment for acromioclavicular (AC) joint instability. METHODS: A systematic review was performed according to PRISMA guidelines. Inclusion criteria were AC joint and coracoclavicular (CC) ligament reconstruction outcomes, English language, human studies, more than 10 patients in the study and a 2-year minimum follow-up. Exclusion criteria were animal studies, cadaveric studies, clinical studies without reported follow-up period or patient-reported outcomes, clinical studies of nonoperative treatment, AC reconstructions with concurrent lateral clavicle fracture, editorial articles, abstracts, presentations, reviews, case reports, and surveys. RESULTS: The systematic review identified 34 studies (939 patients) after inclusion and exclusion criteria application. Postoperative American Shoulder and Elbow Surgeons (ASES) scores ranged from 93.8 to 96, 81.8 to 97.8, and 88.1 for free tendon graft, suspensory devices, and modified Weaver-Dunn techniques, respectively. Postoperative Constant scores were 76.4 to 96.0, 82.6 to 97.8, 85.9 to 97.0, 81 to 96 and 83.0 to 94.6 for free tendon graft, suspensory devices, synthetic ligament devices, modified Weaver-Dunn, and hook plate/K-wires techniques, respectively. All treatment modalities improved patient outcomes; however, hook plates and K-wires had the highest rate of complications (26.3%). Unplanned reoperation rates were 1.2%, 2.8%, 0.9%, 5.4%, and 2.6% in free tendon graft, suspensory devices, synthetic ligament devices, modified Weaver-Dunn, and hook plate/K-wires techniques, respectively. CONCLUSIONS: Comparable subjective outcomes after surgical treatment of AC joint instability was reported for all modalities, with relatively low unplanned reoperation rates. Treatment with hook plate/K-wires was associated with the highest complication rates, and modified Weaver-Dunn had the highest unplanned reoperation rates. LEVEL OF EVIDENCE: Level IV, systematic review of Level I-IV studies. PMID- 29573932 TI - Radiologic and Histologic Evaluation of Proximal Bicep Pathology in Patients With Chronic Biceps Tendinopathy Undergoing Open Subpectoral Biceps Tenodesis. AB - PURPOSE: To correlate preoperative magnetic resonance imaging (MRI) and intraoperative anatomic findings within the proximal long head biceps tendon to histologic evaluation of 3 separate zones of the tendon in patients with chronic biceps tendinopathy. METHODS: Sixteen patients with chronic biceps tendinopathy were treated with open subpectoral biceps tenodesis. Preoperative MRI tendon grading was as follows: normal tendon, increased signal, tendon splitting, incomplete/complete tear. The removed portion of the biceps tendon was split into 3 segments: zone 1, 0-3.5 cm from the labral insertion; zone 2, 3.5-6.5 cm; and zone 3, 6.5-9 cm, and was histologically evaluated using the Bonar score. Tenosynovium adjacent to the tendon was assessed histologically using the Osteoarthritis Research Society International score. CD31, CD3, and CD79a immunohistochemistries were conducted to determine vascularization, T-cell infiltrates, and B-cell infiltrates, respectively. Analysis of variance and Pearson correlations were performed for statistical analysis. RESULTS: Preoperative MRI showed no significant differences in tendon appearance between zones 1-3. Intraoperative findings included nonspecific degenerative SLAP tears or mild/moderate biceps tenosynovitis in all cases. Significantly (P < .001) higher Bonar scores were noted for tendon in zones 1 (7.9 +/- 1.8) and 2 (7.3 +/- 1.5) compared with zone 3 (5.0 +/- 1.1). Cell morphology scores in zone 1 (1.9 +/ 0.4) and zone 2 (1.5 +/- 0.6) were significantly higher than that in zone 3 (0.8 +/- 0.3) (P < .05). Inflammatory tenosynovium showed weak correlation with tendon changes in zone 1 (r = 0.08), zone 2 (r = 0.03), or zone 3 (r = 0.1). CONCLUSIONS: In patients with chronic long head biceps tendinopathy who underwent open subpectoral tenodesis, MRI and intraoperative assessment did not show significant structural abnormalities within the tendon despite significant histopathologic changes. Severity of tendon histopathology was more pronounced in the proximal and mid-portions of the tendon. CLINICAL RELEVANCE: Proximal versus distal biceps tenodesis is a subject of frequent debate. This study contributes to the ongoing evaluation of the characteristics of the proximal biceps in this type of pathologic condition. PMID- 29573933 TI - Capsulodesis Versus Bone Trough Technique in Lateral Meniscal Allograft Transplantation: Graft Extrusion and Functional Results. AB - PURPOSE: To compare the radiographic results (in terms of graft extrusion) and the functional results of lateral meniscus allograft transplantations (MAT) performed with a bony fixation technique or with a soft tissue fixation technique after capsulodesis. METHODS: A prospective series of 29 consecutive lateral MAT was analyzed. The inclusion criterion for MAT was lateral joint line pain due to a previous meniscectomy. Malalignment, patients who had an Ahlback grade greater than II, and patients with a body mass index over 30 were considered as the exclusion criterion to prevent confounding results. Fifteen of the grafts were fixed with a bony fixation technique (group A). The remaining 14 cases (group B) were fixed with sutures through bone tunnels after lateral capsular fixation (capsulodesis). All patients were studied with magnetic resonance imaging to determine the degree of meniscal extrusion at an average of 18 months of surgery (range, 12-48 months). Meniscal extrusion was measured on coronal magnetic resonance imaging. To standardize the results, the percentage of meniscus extruded for each group was also calculated and compared. The functional results were analyzed by means of standard knee scores (Lysholm, Tegner, and visual analog scale). RESULTS: If we consider the first 4 cases of group B as the learning curve of the new technique, we observe that group A had 8 cases (53.3%) of major extrusion, whereas group B had 1 case (7.1%) (P = .02). When comparing the degree of meniscal extrusion with the type of fixation employed, an even lower percentage of extruded menisci was found in group B (P = .01). The final follow-up Lysholm score in group A was 94.33 +/- 5.96 (P < .001) and 91.43 +/- 6.19 (P < .001) in group B. The median follow-up Tegner score significantly improved from 4 (range, 2-5) to 7 (range, 6-9) in group A (P < .001) and from 4 (range, 3-5) to 7 (range, 6-8) in group B (P < .001). The average visual analog scale score dropped down 5.87 and 7.29 points in groups A and B, respectively (P < .001). The Knee Injury and Osteoarthritis Outcome Score improved from 51.98 +/- 2.84 to 90.88 +/- 7.53 in group A (P < .001) and from 50.44 +/- 2.32 to 92.01 +/- 6.71 in group B (P < .001). Patient satisfaction with regard to the procedure stood at a mean of 3.6 +/- 0.2 points out of a maximum of 4 in group A and 3.8 +/ 0.4 in group B. There were no complications in this series. CONCLUSIONS: The capsulodesis technique in lateral MAT proved not to be statistically different at decreasing the degree of meniscal extrusion with respect to the bone-bridge fixation. If the first 4 cases using the new capsulodesis technique had not included in the results, the capsulodesis technique would have effectively presented better results relative to the degree of meniscal extrusion compared with the bone-bridge fixation technique. In addition, the functional results were similar. LEVEL OF EVIDENCE: Level II, prospective comparative study. PMID- 29573934 TI - Influence of Muscle Fatty Degeneration on Functional Outcomes After Endoscopic Gluteus Medius Repair. AB - PURPOSE: To report the early outcomes of endoscopic repair of tears of the gluteus medius tendon and to determine whether the fatty degeneration had an influence on clinical results. METHODS: Between October 2012 and June 2014, data were prospectively collected and retrospectively reviewed for all patients who underwent endoscopic gluteus medius repair. Patients were assessed pre- and postoperatively using the modified Harris hip score, the nonarthritic hip score, and visual analog scale for pain. The gluteus minimus and the 3 distinct parts of the gluteus medius (anterior, middle, and posterior) were assigned a grade of fatty degeneration on preoperative magnetic resonance imaging scans. RESULTS: Twenty-two hips (in 20 patients) were assessed with the mean follow-up of 31.7 months (range: 24 to 47 months). There were 15 partial-thickness and 7 full thickness tears. No patient was lost to follow-up. The mean age at the time of surgery was 66 years (range: 45 to 82 years). Of the 20 magnetic resonance imaging-assessed hips included in the study, 14 had fatty degeneration of the gluteus medius (partial-thickness tears: n = 8, full-thickness tears: n = 6). The mean gluteus medius fatty degeneration index was 1.57 (range: 0.33 to 3.33). Postoperative improvement was seen in modified Harris hip score (33.7 points vs 80.2 points, P = .0001), nonarthritic hip score (47.7 points vs 76.8 points, P = .0001), and in the visual analog scale for pain (7.2 vs 3.2, P < .05). Increasing preoperative fatty degeneration index of the gluteus medius correlated with decreased postoperative functional hip score values (regression coefficient, 0.5839; P < .0001). Tear characteristics (partial or full-thickness) did not correlate with fatty degeneration or muscular atrophy and did not affect postoperative outcomes. CONCLUSIONS: Endoscopic surgical repair can be an effective treatment of gluteus medius tears in the short term. Fatty degeneration of the gluteus medius and minimus has a negative impact on clinical outcomes of endoscopic gluteus medius repair.

PMID- 29573936 TI - Accuracy of Dual-Energy Virtual Monochromatic CT Numbers: Comparison between the Single-Source Projection-Based and Dual-Source Image-Based Methods. AB - RATIONALE AND OBJECTIVES: To investigate the accuracy of dual-energy virtual monochromatic computed tomography (CT) numbers obtained by two typical hardware and software implementations: the single-source projection-based method and the dual-source image-based method. MATERIALS AND METHODS: A phantom with different tissue equivalent inserts was scanned with both single-source and dual-source scanners. A fast kVp-switching feature was used on the single-source scanner, whereas a tin filter was used on the dual-source scanner. Virtual monochromatic CT images of the phantom at energy levels of 60, 100, and 140 keV were obtained by both projection-based (on the single-source scanner) and image-based (on the dual-source scanner) methods. The accuracy of virtual monochromatic CT numbers for all inserts was assessed by comparing measured values to their corresponding true values. Linear regression analysis was performed to evaluate the dependency of measured CT numbers on tissue attenuation, method, and their interaction. RESULTS: Root mean square values of systematic error over all inserts at 60, 100, and 140 keV were approximately 53, 21, and 29 Hounsfield unit (HU) with the single-source projection-based method, and 46, 7, and 6 HU with the dual-source image-based method, respectively. Linear regression analysis revealed that the interaction between the attenuation and the method had a statistically significant effect on the measured CT numbers at 100 and 140 keV. CONCLUSIONS: There were attenuation-, method-, and energy level-dependent systematic errors in the measured virtual monochromatic CT numbers. CT number reproducibility was comparable between the two scanners, and CT numbers had better accuracy with the dual-source image-based method at 100 and 140 keV. PMID- 29573937 TI - Comparison of Local Injection of Fresh Frozen Plasma to Traditional Methods of Hemostasis in Minimally Invasive Procedures. AB - RATIONALE AND OBJECTIVES: To evaluate different techniques for reducing hemorrhagic complications in coagulopathic patients with elevated international normalized ratio having an image-guided percutaneous invasive procedure; techniques included systemic transfusion of fresh frozen plasma (FFP), local injection of FFP, percutaneous injection of gelatin sponge, and percutaneous placements of angiographic coils. MATERIALS AND METHODS: Retrospective review of 232 consecutive patients with known coagulopathy undergoing image-guided minimally invasive procedures were selected. Ninety-one patients had local FFP injected, 40 patients underwent local synthetic gelatin injection, 16 patients had percutaneous coil embolization, and 85 patients received systemic FFP. The number of bleeds, complications related to bleeds, and systemic complications were recorded. A 30 cc threshold was used to delineate significant bleeding. RESULTS: No patients experienced clinically significant or insignificant bleeding with local FFP injection (P value <.05). Other local hemostatic methods (Gelfoam, systemic FFP, and coil embolization) were associated with higher levels of bleeding (12.5%, 17.1%, 37.5%, respectively) and complications (7.5%, 31.4%, 37.5%, respectively). Systemic FFP infusion was associated with respiratory, infectious, and mortal complications. CONCLUSIONS: Local injection of blood products provides a safe and efficacious hemostatic agent to reduce the incidence of postprocedural bleeding. The technique is associated with lower rates of bleeding and systemic complications when compared to other local and systemic techniques. Further randomized prospective studies with a larger patient cohort need to be performed to corroborate these initial findings.

PMID- 29573939 TI - Differentiation of Benign and Malignant Thyroid Nodules by Using Comb-push Ultrasound Shear Elastography: A Preliminary Two-plane View Study. AB - RATIONALE AND OBJECTIVES: Low specificity of traditional ultrasound in differentiating benign from malignant thyroid nodules leads to a great number of unnecessary (ie, benign) fine-needle aspiration biopsies that causes a significant financial and physical burden to the patients. Ultrasound shear wave elastography is a technology capable of providing additional information related to the stiffness of tissues. In this study, quantitative stiffness values acquired by ultrasound shear wave elastography in two different imaging planes were evaluated for the prediction of malignancy in thyroid nodules. In addition, the association of elasticity measurements with sonographic characteristics of thyroid gland and nodules is presented. MATERIALS AND METHODS: A total number of 155 patients (106 female and 49 male) (average age 57.48 +/- 14.44 years) with 173 thyroid nodules (average size 24.89 +/- 15.41 mm, range 5-68 mm) scheduled for fine-needle aspiration biopsy were recruited from March 2015 to May 2017. Comb-push shear elastography imaging was performed at longitudinal and transverse anatomic planes. Mean (Emean) and maximum (Emax) elasticity values were obtained. RESULTS: Measurements at longitudinal view were statistically significantly higher than measurements at transverse view. Nodules with calcifications were associated with increased elasticity, and nodules with a vascular component or within an enlarged thyroid gland (goiter) were associated with a lower elasticity value. Receiver operating characteristic curve analysis was performed for Emean and Emax at each imaging plane and for the average of both planes. Sensitivity of 95.45%, specificity of 86.61%, 0.58 positive predictive value, and 0.99 negative predictive value were achieved by the average of the two planes for each Emean and Emax parameters, with area under the curve of 92% and 93%, and a cutoff value of 49.09 kPa and 105.61 kPa, respectively. CONCLUSIONS: The elastic properties of thyroid nodules showed promise to be a good discriminator between malignant and benign nodules (P < .0001). However, probe orientation and internal features such as calcifications, vascular component, and goiter may influence the final elastography measurements. A larger number of malignant nodules need to be studied to further validate our results. PMID- 29573941 TI - Encorafenib plus binimetinib versus vemurafenib or encorafenib in patients with BRAF-mutant melanoma (COLUMBUS): a multicentre, open-label, randomised phase 3 trial. AB - BACKGROUND: Combined BRAF-MEK inhibitor therapy is the standard of care for BRAFV600-mutant advanced melanoma. We investigated encorafenib, a BRAF inhibitor with unique target-binding properties, alone or in combination with the MEK inhibitor binimetinib, versus vemurafenib in patients with advanced BRAFV600 mutant melanoma. METHODS: COLUMBUS was conducted as a two-part, randomised, open label phase 3 study at 162 hospitals in 28 countries. Eligible patients were aged 18 years or older and had histologically confirmed locally advanced (American Joint Committee on Cancer [AJCC] stage IIIB, IIIC, or IV), unresectable or metastatic cutaneous melanoma, or unknown primary melanoma; a BRAFV600E or BRAFV600K mutation; an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; and were treatment naive or had progressed on or after previous first-line immunotherapy. In part 1 of the study, patients were randomly assigned (1:1:1) via interactive response technology to receive either oral encorafenib 450 mg once daily plus oral binimetinib 45 mg twice daily (encorafenib plus binimetinib group), oral encorafenib 300 mg once daily (encorafenib group), or oral vemurafenib 960 mg twice daily (vemurafenib group). The primary endpoint was progression-free survival by blinded independent central review for encorafenib plus binimetinib versus vemurafenib. Efficacy analyses were by intention-to treat. Safety was analysed in patients who received at least one dose of study drug and one postbaseline safety assessment. The results of part 2 will be published separately. This study is registered with ClinicalTrials.gov, number NCT01909453, and EudraCT, number 2013-001176-38. FINDINGS: Between Dec 30, 2013, and April 10, 2015, 577 of 1345 screened patients were randomly assigned to either the encorafenib plus binimetinib group (n=192), the encorafenib group (n=194), or the vemurafenib group (n=191). With a median follow-up of 16.6 months (95% CI 14.8-16.9), median progression-free survival was 14.9 months (95% CI 11.0 18.5) in the encorafenib plus binimetinib group and 7.3 months (5.6-8.2) in the vemurafenib group (hazard ratio [HR] 0.54, 95% CI 0.41-0.71; two-sided p<0.0001). The most common grade 3-4 adverse events seen in more than 5% of patients in the encorafenib plus binimetinib group were increased gamma-glutamyltransferase (18 [9%] of 192 patients), increased creatine phosphokinase (13 [7%]), and hypertension (11 [6%]); in the encorafenib group they were palmoplantar erythrodysaesthesia syndrome (26 [14%] of 192 patients), myalgia (19 [10%]), and arthralgia (18 [9%]); and in the vemurafenib group it was arthralgia (11 [6%] of 186 patients). There were no treatment-related deaths except for one death in the combination group, which was considered possibly related to treatment by the investigator. INTERPRETATION: Encorafenib plus binimetinib and encorafenib monotherapy showed favourable efficacy compared with vemurafenib. Overall, encorafenib plus binimetinib appears to have an improved tolerability profile compared with encorafenib or vemurafenib. Encorafenib plus binimetinib could represent a new treatment option for patients with BRAF-mutant melanoma. FUNDING: Array BioPharma, Novartis. PMID- 29573942 TI - RE: Rydzewska et al.

AB - Schizophrenia risk has been linked to urbanization, but the underlying mechanism remains unknown. Green space is hypothesized to positively influence mental health and might mediate risk of schizophrenia by mitigating noise and particle pollution exposure, stress relief, or other unknown mechanisms. The objectives for this study were to determine if green space are associated with schizophrenia risk, and if different measures of green space associate differently with risk. We used satellite data from the Landsat program to quantify green space in a new data set for Denmark at 30*30m resolution for the years 1985-2013. The effect of green space at different ages and within different distances from each person's place of residence on schizophrenia risk was estimated using Cox regression on a very large longitudinal population-based sample of the Danish population (943,027 persons). Living at the lowest amount of green space was associated with a 1.52 fold increased risk of developing schizophrenia compared to persons living at the highest level of green space. This association remained after adjusting for known risk factors for schizophrenia: urbanization, age, sex, and socioeconomic status. The strongest protective association was observed during the earliest childhood years and closest to place of residence. This is the first nationwide population based study to demonstrate a protective association between green space during childhood and schizophrenia risk; suggesting limited green space as a novel environmental risk factor for schizophrenia. This study supports findings from other studies highlighting positive effects of exposure to natural environments for human health. PMID- 29573947 TI - Blocking Bone Loss with l-BAIBA.

AB - BACKGROUND: Vitamin D has been implicated in the prevention of heart failure. However the underlying mechanism remains unclear. We hypothesised that these effects may be partially mediated by cardiac stem/progenitor cells (CPCs). Therefore, we examined the effects of 1,25-dihydroxyvitamin D3 (1,25D) on cell cycle activity and differentiation of a previously described CPC population called cardiac colony-forming unit fibroblasts (cCFU-Fs). METHODS: cCFU-Fs were isolated from adult male C57Bl/6 mouse hearts using fluorescence-activated cell sorting. The effect of 1,25D on cell proliferation and differentiation were was assessed by colony-forming and fibroblast differentiation assays. Cell cycle was analysed by flow cytometry. Mice with induced myocardial infarction (MI) were treated with 1,25D or vehicle controls and cardiac function assessed by echocardiography. RESULTS: 1,25D dose-dependently increased expression of vitamin D receptor (Vdr) and reduced large colony formation. Addition of 1,25D to cCFU-Fs slowed cell proliferation, promoted cell cycle arrest and decreased expression of pro-fibrotic factors during TGF-beta-induced fibroblast differentiation of cCFU Fs. After MI, 1,25D-treated mice had less left ventricular wall thinning and significant improvement in left ventricular systolic function compared to vehicle treated controls. Although no significant changes in myocardial fibrotic area and cardiomyocyte size were noted, treatment with 1,25D significantly inhibited cardiac interstitial cell proliferation after MI. CONCLUSIONS: Vitamin D signalling promotes cardioprotection after myocardial infarction. This may be through modulation of cCFU-F cell cycle. The role of 1,25D and VDR in regulating cardiac stem/progenitor cell function therefore warrants further investigation. PMID- 29573958 TI - Beta 2-Microglobulin and the Severity of Coronary Stenosis in Patients With Acute Coronary Syndrome. AB - BACKGROUND: Previous studies have shown that beta 2-microglobulin (B2M) could predict all-cause mortality and cardiovascular mortality in various groups of people. However, the relationship between B2M and severity of coronary stenosis in patients with acute coronary syndrome has not been established. METHODS: We enrolled 872 consecutive patients admitted with acute coronary syndrome in our study. All participants underwent coronary angiography examination or stent implantation after admission. The severity of coronary stenosis was assessed by Gensini score and the presentation of triple-vessel disease. B2M and other biochemical parameters were measured. All subjects were divided into quartiles of B2M. Multivariate linear regression and logistic regression were applied in the analysis. RESULTS: Gensini score and the prevalence of triple-vessel disease were elevated in accordance with increasing B2M quartiles (p=0.002 and p<0.001, respectively). Multivariate regression showed diabetes (p=0.031), high sensitivity C-reactive protein (hs-CRP, p=0.043) and B2M (p=0.006) were positively correlated with Gensini score. Logistic regression analysis revealed that the crude and fully adjusted odds ratios of triple-vessel disease were 2.34 (95% CI: 1.58-3.46) and 1.97 (95% CI: 1.14-3.40) in the fourth quartile of B2M compared with the first quartile, respectively. However, no interactive relationships were found in subgroup analysis by estimated glomerular filtration rate or hs-CRP in the above associations, neither in the distribution of Gensini score (p for interaction>0.05 for both). CONCLUSION: Our data indicated that B2M was an independent risk factor of coronary stenosis in patients with acute coronary syndrome.

PMID- 29573961 TI - Impact of dosage timing of once-daily inhaled corticosteroids in asthma: A systematic review and meta-analysis. AB - BACKGROUND: Once-daily inhaled corticosteroids (ICSs) are widely used as first line therapy in patients with asthma. OBJECTIVE: To compare the efficacy of ICSs administered once daily in the morning or evening as determined by lung function. METHODS: Medline, Embase, and the Cochrane Central Register were searched for relevant clinical trials. The primary outcome was lung function assessed as trough forced expiratory volume in 1 second and peak expiratory flow at end point. RESULTS: Eight randomized clinical trials involving 1,234 patients were analyzed. The total number of patients treated with once-daily ICS in the morning and evening was 628 and 606, respectively. Pooled estimates showed that ICS administered once daily in the evening resulted in mild improvements in trough forced expiratory volume in 1 second (mean difference 0.05 L; 95% confidence interval 0.01-0.09; P = .026; I2 = 22.5%) and morning peak expiratory flow (mean difference 13.92 L/min; 95% confidence interval 5.77-22.06; P = .001; I2 = 13%) at end point compared with morning dosing. The change in use of rescue medicine and the incidence of adverse events with once-daily ICS were not significantly different between the 2 dosing times. CONCLUSION: Compared with morning dosing, ICSs administered once daily in the evening seemed to provide some benefits in lung function for patients with asthma. However, because of methodologic limitations, further large-scale randomized clinical trials for dosing time of once-daily ICSs are needed. PMID- 29573962 TI - Natural history and management of splanchnic artery aneurysms in a single tertiary referral center. AB - OBJECTIVE: Splanchnic artery aneurysms (SAAs) are rare, and little is known about their natural history and management. We reviewed our single-center experience in managing this population of patients. METHODS: A retrospective review of the Yale radiologic database from January 1999 to December 2016 was performed. Only patients with an SAA and a computed tomography scan of the abdomen were selected for review. Demographics of the patients, aneurysm characteristics, management, postoperative complications, and follow-up data were collected. Our primary outcomes included aneurysm growth rate and risk of rupture in those patients managed nonoperatively and morbidity and mortality of those SAA patients who underwent operative intervention. RESULTS: There were 122 patients with 138 SAAs identified; 77 were male (62%), with a mean age of 66 years (range, 25-94 years). On computed tomography, 56 (45%) had previously diagnosed or concomitant aneurysms elsewhere. Of the patients managed nonoperatively, 101 patients (79%) had 108 SAAs; in the operative intervention group, 25 (21%) patients had 30 SAAs. The mean overall vessel diameter was 1.76 +/- 0.83 cm. The diameter of observed and operatively repaired SAAs was 1.58 +/- 0.56 cm and 2.41 +/- 1.23 cm, respectively (P = .00001). Mean follow-up was 50 +/- 42 months for nonoperative management without any adverse events related to SAA, including 10 patients with SAA >2.0 cm. The mean observed growth rate for SAA was 0.064 +/- 0.18 cm/y. All symptomatic patients who presented with severe abdominal pain (n = 11 [44%]) underwent operative intervention. Five patients presented with a ruptured SAA (3.6%; range, 2.3-5.0 cm); all of them except one underwent operative intervention. Other indications for repair included large size in seven, rapid growth in two, other open abdominal surgical procedures in two, multiple aneurysms in one, and desire to pursue fertility treatment in one. Operative repair included 14 (56%) endovascular embolizations and 11 (44%) open abdominal operations. After endovascular embolization, two patients underwent abdominal operation for hemorrhage and splenectomy. Open repairs included bypasses in six, splenectomy in two, resection in two, and plication in one. Two patients had postoperative acute kidney injury that resolved and one died of multisystem organ failure. One bypass occluded without sequelae. On multivariable regression analysis, female sex (P = .02) was associated with faster growth rate, and a history of smoking (P = .04) was associated with slower growth rate. CONCLUSIONS: It seems reasonable to observe asymptomatic patients with an SAA <2.0 cm because of the slow growth rate (0.064 +/- 0.18 cm/y) and benign behavior. When intervention is needed, both open and endovascular options should be considered. PMID- 29573963 TI - High rate of over-staging of Barrett's neoplasia with endoscopic ultrasound: Systemic review and meta-analysis. AB - BACKGROUND: The use of endoscopic ultrasound (EUS) to stage patients with Barrett's esophagus (BE) with suspected neoplasia is controversial due to high rates of over-staging. However, this rate of over-staging has not been adequately investigated or quantified. AIM: To determine the rate of over-staging related EUS in this population. METHODS: Search included Medline, Embase, Web of Science, and Cochrane Central ending on 9/30/2016. The primary effect-estimate of interest was the false positive rate of advanced disease on EUS at the tumor level (T1a vs. T1b). Secondary outcomes included false detection rate, false negative rate, accuracy, sensitivity, and specificity. Study heterogeneity was assessed using the I2 and Cochrane's Q. RESULTS: Of 1872 studies, 11 met our inclusion criteria totaling 895 patients. Based on random effects models, the pooled FPR for advanced disease was 9.1% ([6.5-12.5%], p<0.001). Tests of heterogeneity showed no significant heterogeneity for this outcome. The pooled false negative rate was 9.2% [95%CI: 4.7-17.3%], p<0.01. Overall, the pooled accuracy of EUS results in BE neoplasia patients was low at 74.6% [58.7-85.8%], p=0.004. CONCLUSIONS: The use of EUS in BE patients with dysplasia and early neoplasia results in a large proportion of patients falsely over-staged and under-staged. PMID- 29573964 TI - An Electronic Ecological Momentary Assessment Study to Examine the Consumption of High-Fat/High-Sugar Foods, Fruits/Vegetables, and Affective States Among Women. AB - OBJECTIVE: To examine the associations between high-fat/high-sugar foods (HFHS) and fruit and vegetable (FV) consumption and affective states in women. METHODS: The researchers used electronic ecological momentary assessment to capture HFHS and FV consumption in the past 2 hours (predictor) and current affective states (outcome) across 1 week among 202 women. Multilevel linear regression was conducted. Weight status was tested as a moderator. RESULTS: Consumption of FV in the past 2 hours was positively associated with feeling happy (P < .05). Women who consumed more HFHS or fewer FV than others in the study reported higher average sadness (both P < .05). Overweight or obese women who reported more frequent HFHS consumption than others had higher average stress than normal weight women (P < .05). CONCLUSIONS AND IMPLICATIONS: The association between HFHS consumption and stress might be stronger in overweight or obese than normal weight women. Future studies could further enhance the electronic ecological momentary assessment method to explore other time-varying moderators and mediators of food consumption and affect. PMID- 29573965 TI - The evolution of bladder cancer genomics: What have we learned and how can we use it? AB - BACKGROUND: With advancements in molecular biology techniques, great progress has been made in the understanding of urothelial carcinoma pathogenesis. OBJECTIVE: To examine the historic description of molecular alterations in bladder cancer and their evolution towards our current comprehension of the biology of the disease. RESULTS: Historically, a two-pathway model was described from histological and cytogenetic studies: low-grade papillary non-muscle invasive bladder cancers (NMIBC) were described to arise from epithelial hyperplasia with loss of chromosome 9 as an early event, whereas muscle-invasive bladder cancers (MIBC) were considered to develop from dysplasia, associated with genetic instability. Although there could be connections between the 2 pathways, NMIBC and MIBC were largely believed to develop secondary to different molecular alterations. Next-generation sequencing has allowed important insights into cancer biology and a better understanding of the pathways involved in bladder cancer pathogenesis and heterogeneity. Urothelial carcinoma has been found to have a high frequency of somatic mutations compared to other solid tumors, including several mutations in multiple signaling pathways, such as cell cycle regulators (TP53, RB1), RTK/RAS/RAF pathway, PI3K/AKT/mTOR pathway and TERT gene promoter. Epigenetic changes and mutations in chromatin remodeling genes are especially frequent in bladder cancer. Mutations in FGFR3 and KDM6A are more common in NMIBC than in MIBC, whereas mutations in TP53 and KMT2D are more common in MIBC, suggesting the previously hypothesized 2 different pathways, with a subset of tumors progressing from NMIBC to MIBC. Using comprehensive RNA expression profiling studies, at least 5 subtypes of bladder cancer have been identified, the most fundamental division being Basal/Squamous-like and Luminal. These subtypes have different prognoses, natural histories and responses to systemic treatments: Luminal subtypes are enriched with papillary histology and have a better prognosis, while Basal/Squamous-like subtypes are enriched with squamous features, are associated with advanced stage at presentation, and portend a worse prognosis. CONCLUSION: This new understanding of bladder cancer will optimistically translate into better understanding of this heterogeneous disease and lead to improvement in patient outcome and quality of life through better tailored treatments.

AB - Long non-coding RNAs (lncRNAs) are involved in many biological processes, such as immune response, development, differentiation and gene imprinting and are associated with diseases and cancers. But the functions of the vast majority of lncRNAs are still unknown. Predicting the biological functions of lncRNAs is one of the key challenges in the post-genomic era. In our work, We first build a global network including a lncRNA similarity network, a lncRNA-protein association network and a protein-protein interaction network according to the expressions and interactions, then extract the topological feature vectors of the global network. Using these features, we present an SVM-based machine learning approach, PLNRGO, to annotate human lncRNAs. In PLNRGO, we construct a training data set according to the proteins with GO annotations and train a binary classifier for each GO term. We assess the performance of PLNRGO on our manually annotated lncRNA benchmark and a protein-coding gene benchmark with known functional annotations. As a result, the performance of our method is significantly better than that of other state-of-the-art methods in terms of maximum F-measure and coverage. PMID- 29573967 TI - Human challenge trials in vaccine development, Rockville, MD, USA, September 28 30, 2017. AB - The International Alliance for Biological Standardization organized the second workshop on human challenge trials (HCT) in Rockville, MD, in September 2017. The objective of this meeting was to examine the use of HCT, in response to the continuing human suffering caused by infectious diseases, preventable by the development of new and improved vaccines. For this, the approach of HCT could be valuable, as HCT can provide key safety, tolerability, immunogenicity, and efficacy data, and can be used to study host-pathogen biology. HCT can generate these data with speed, efficiency and minimal expense, albeit not with the same level of robustness as clinical trials. Incorporated wisely into a clinical development plan, HCT can support optimization or down-selection of new vaccine candidates, assuring that only the worthiest candidates progress to field testing. HCT may also provide pivotal efficacy data in support of licensure, particularly when field efficacy studies are not feasible. Many aspects of HCT were discussed by the participants, including new and existing models, standardization and ethics. A consensus was achieved that HCT, if ethically justified and performed with careful attention to safety and informed consent, should be pursued to promote and accelerate vaccine development. PMID- 29573968 TI - Systematic review of care needs for older patients treated with anticancer drugs. AB - OBJECTIVE: When treated with anticancer therapies, a number of issues are raised for older patients such as physical needs (coping with symptoms and side-effects) or psychological needs. Geriatric tailored interventions addressing these needs may be effective in terms of improving quality of life of our patients. METHODS: A systematic review was performed in September 2017 in MEDLINE. All reports assessing older patients with cancer care needs in the context of anticancer systemic therapy were reviewed. RESULTS: A total of 357 articles were analyzed. From these, 35 studies were included in the analysis. Compared to younger patients, the elderly had less supportive care needs. While older patients asked for less information than their younger counterparts, they still requested information on diagnosis, seriousness of the disease, chances of cure, spread of the disease, recovery, courses of illness, possible consequences, treatment procedures, treatment options, possible side effects and how to deal with them, and what they could do in daily life. When taking into consideration the various needs as assessed by the "Supportive Care Needs Survey", physical and daily living were the most frequently reported needs with emphasis on nutrition, coping with physical symptoms, dealing with side effects of treatment, and performing usual physical tasks and activities. CONCLUSION: Information demand seemed moderate but a great deal of attention was paid to nutrition and well-being. PMID- 29573969 TI - Significance of stereotactic body radiotherapy in older patients with early stage non-small cell lung cancer. AB - OBJECTIVES: Our aim was to investigate long-term treatment outcomes in older patients with early stage non-small cell lung cancer (NSCLC) and the presence or absence of therapeutic benefits, using the G8 screening tool. METHODS: We retrospectively studied 43 older patients (median age 78 years, range 65-89 years) with stage I lung tumors (T1 and T2 tumors in 34 and 9 patients, respectively), who underwent stereotactic body radiotherapy (SBRT). This study assessed outcomes in a cohort of patients who received geriatric assessments, performed between 2004 and 2011, before the start of their SBRT regimen. Any questions asked to patients before undergoing treatment were applied to the G8 screening tool. RESULTS: G8 scores ranged from 8 to 16 (median, 12) in all patients (n = 43), while G8 scores in the T1 and T2 groups ranged from 9 to 16 (median, 13) and 8 to 15 (median, 12), respectively. In patients with G8 scores <=12, the 2-year and 5-year survival rates were 56.1% and 28% respectively, while the rates were 94.1% and 68.4%, respectively, in patients with G8 scores >=13 (P = 0.0014). During long-term follow-up, 25.9% of the patients (n = 43) died of the primary disease, NSCLC, and 34.9% of patients died of other diseases or other types of cancer. CONCLUSION: SBRT may be effective, even in older adults. Regardless of age, SBRT improved the long-term survival of patients only with G8 scores >=13. The G8 screening tool may aid in determining whether older patients with comorbidities would benefit from SBRT. PMID- 29573970 TI - Perceptual averaging of facial expressions requires visual awareness and attention. AB - Humans, as highly social animals, are regularly exposed to the faces of conspecifics-often more than one at a time. This feature of social living is important for understanding face perception, not just because it means that information from faces is available in bulk, but also because it changes the way individuals are perceived. For instance, when two faces are seen nearby one another, they tend to look like each other. This phenomenon of perceptual averaging is robust when both faces are seen and attended. But in everyday life, some faces may not receive the full benefit of attention, or they may not be visible at all. We evaluated whether perceptual averaging of relatively complex and simple information on faces, including facial expression and head orientation, can still occur even in these circumstances. In particular, we used object-substitution masking (OSM) and a dual-task designed to disrupt visual awareness and attention, respectively, during evaluations of briefly presented face pairs. Disruptions of awareness or attention eliminated averaging of facial expression, whereas orientation averaging persisted in spite of these challenges. These results demonstrate boundary conditions for the process of perceptual averaging. More generally, they provide insight into how the visual system processes multitudes of objects, both simple and complex, both with and without attention and awareness. PMID- 29573971 TI - Digenic variants of planar cell polarity genes in human neural tube defect patients. AB - Neural tube defects (NTDs) are considered to be a complex genetic disorder, although the identity of the genetic factors remains largely unknown. Mouse model studies suggest a multifactorial oligogenic pattern of inheritance for NTDs, yet evidence from published human studies is surprisingly absent. In the present study, targeted next-generation sequencing was performed to screen for DNA variants in the entire coding regions and intron-exon boundaries of targeted genes using DNA samples from 510 NTD cases. These candidate genes were PCP genes, including VANGL1, VANGL2, CELSR1, SCRIB, DVL2, DVL3 and PTK7. Candidate variants were validated using Sanger sequencing. A total of 397 single nucleotide variants(SNVs) were identified with a mean depth of approximately 570*. Of these identified SNVs, 74 were predicted to affect protein function and had a minor allele frequency of <0.01 or unknown. Among these 74 missense SNVs, 10 were identified from six NTD cases that carried two mutated genes. Of the six NTD cases, three spina bifida cases and one anencephaly case carried digenic variants in the CELSR1 and SCRIB gene; one anencephaly case carried variants in the CELSR1 and DVL3 gene; and one spina bifida case carried variants in the PTK7 and SCRIB genes. Three cases that parental samples were available were confirmed to be compound heterozygous. None of the digenic variants were found in the 1000 genome database. The findings imply that genetic variation might interact in a digenic fashion to generate the visible NTD phenotypes and emphasize the importance of these genetic interactions in the development of NTDs in humans.

AB - The molecular mechanisms underpinning the process of endothelial-to-mesenchymal transition (EndMT) are mostly unknown. Recently Xiong and colleagues explored for the first time the metabolic changes associated with the activation of the mesenchymal program in endothelial cells, and found that reprogramming of fatty acid oxidation pivotally regulates EndMT. PMID- 29573972 TI - Do Male Hearts Break Differently? PMID- 29573974 TI - The risk of neurodevelopmental disorders following Thimerosal-containing Hib vaccine in comparison to Thimerosal-free Hib vaccine administered from 1995 to 1999 in the United States. AB - Investigators postulated that early-life exposure to organic mercury (Hg) significantly increases the risk of childhood neurodevelopmental disorders (NDs). The Vaccine Adverse Event Reporting System database was utilized to conduct a hypothesis testing case-control study by evaluating 3486 total adverse event reports reported following Haemophilus influenza type b (Hib) vaccination. Exposed subjects received a Thimerosal-containing formulation (HIBTITERTM, Wyeth Lederle), while unexposed subjects received a Thimerosal-free formulation (PEDVAXHIBTM, Merck). Subjects were included if they received either of these two Hib vaccine formulations between 1995 and 1999. Cases were defined as adverse event reports with a reported outcome of autism, developmental delay, psychomotor delay, or NDs in general. Cases with reported outcomes of febrile convulsions, pyrexia, or injection site pain, all of which have no biologically plausible relation to Hg exposure, were also examined. Controls were defined as adverse event reports without any mention of the specific case outcome examined. Cases of reported autism (odds ratio (OR) = 2.75, p < 0.02), developmental delay (OR = 5.39, p < 0.01), psychomotor disorder (OR = 2.38, p < 0.03), and neurodevelopmental disorder in general (OR = 2.70, p < 0.001) were each significantly more likely than their respective controls to receive Thimerosal containing Hib vaccine than Thimerosal-free Hib vaccine. Significant effects for neurodevelopmental disorder in general were observed for males (OR = 2.52, p < 0.005), but not females when separated by gender. For the outcomes that had no biologically plausible relation to Hg exposure, the cases were no more likely than their respective controls to receive Thimerosal-containing Hib vaccine than Thimerosal-free Hib vaccine. This study provides suggestive evidence of an association between Thimerosal and neurodevelopmental outcomes and provides support for carrying out additional well-designed studies examining the association between Thimerosal-containing vaccines and a wide range of neurodevelopmental outcomes. PMID- 29573975 TI - Can a polypill one single tablet combat different cardiovascular risk factors? AB - Polypharmacy is defined as the use of two or more drugs simultaneously. Cardiovascular drugs and antihypertensives are commonly prescribed for treatment of cardiovascular disease (CVD), especially in elderly patients. Recent studies in patients with a history of CVD demonstrated that the fixed-dose combination of cardiovascular drugs in a polypill retain their individual efficacy, safety, and tolerability, thus have the potential to improve medication adherence and multiple risk factor control, thereby improving patient outcomes in secondary cardiovascular prevention. Since the initial conception of the fixed-dose polypill, just over a decade ago, only six large randomized trials assessing the efficacy and safety of this innovative concept have been completed (one is still ongoing). The results demonstrate that the polypill therapy significantly improved adherence, lowered systolic blood pressure, and low-density lipoprotein cholesterol, compared with usual care, in patients at high risk for CVD, especially among those who were undertreated at baseline. Correspondingly, further studies showed that the strengths of the polypill include better adherence, equivalent or better risk factor control, and improved quality of life among polypill users, as compared with usual care. However, the long-term outcome of the polypill on CVD events and mortality are unavailable and are currently being studied in clinical trials.

PMID- 29573977 TI - Triple Negative Apocrine Carcinomas as a Distinct Subtype of Triple Negative Breast Cancer: A Case-control Study. AB - BACKGROUND: Invasive triple negative apocrine carcinoma (TNAC) of the breast is a rare type of triple negative breast cancer. Several studies reported significantly distinct prognosis for TNAC when compared with most of the non apocrine triple negative (NATN) tumors. This is a case-control study reporting onoutcomes from our long-term single-center experience. PATIENTS AND METHODS: We analyzed the clinicopathologic features of a series of 46 TNAC tumors treated in a 15-year period. Tumor characteristics and outcomes have been compared with a homogeneous control series of 43 NATN tumors treated during the same follow-up period. Local relapse-free survival (LRFS), distant metastases-free survival (DMFS), and overall survival (OS) have been evaluated. RESULTS: LRFS in the TNAC group was 85% and 78% at 5 and 10 years, respectively. LRFS in the NATN group was 90% and 79% at 5 and 10 years, respectively (hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.41-3.19; P = .80). DMFS in the TNAC group was 85% and 85% at 5 and 10 years, respectively. DMFS in the NATN group was 85% and 75% at 5 and 10 years, respectively (HR, 0.39; 95% CI, 0.14-1.08; P = .071). OS in the TNAC group was 86% and 83% at 5 and 10 years, respectively. OS in the NATN group was 86% and 63% at 5 and 10 years, respectively. OS was significantly better in the TNAC group (HR, 0.45; 95% CI, 0.20-0.99; P = .049). CONCLUSIONS: TNAC seems to represent a distinct group of triple negative breast cancer, characterized by a favorable long-term outcome when compared with NATN tumors. PMID- 29573978 TI - Pathogen clearance and immune adherence "revisited": Immuno-regulatory roles for CRIg. AB - Rapid elimination of microbes from the bloodstream, along with the ability to mount an adaptive immune response, are essential for optimal host-defense. Kupffer cells are strategically positioned in the liver sinusoids and efficiently capture circulating microbes from the hepatic artery and portal vein, thus preventing bacterial dissemination. In vivo and in vitro studies have probed how complement receptor of the immunoglobulin superfamily (CRIg), also referred to as Z39Ig and V-set and Ig domain-containing 4 (VSIG4), acts as a critical player in pathogen recognition and clearance. While recent data suggested that CRIg may bind bacterial cell wall components directly, the single transmembrane receptor is best known for its interaction with complement C3 opsonization products on the microbial surface. On Kupffer cells, CRIg must capture opsonized microbes against the shear forces of the blood flow. In vivo work reveals how immune adherence (IA), a process in which blood platelets or erythrocytes associate with circulating bacteria, plays a critical role in regulating pathogen capture by CRIg under flow conditions. In addition to its typical innate immune functions, CRIg was shown to directly and indirectly influence adaptive immune responses. Here, we review our current understanding of the diverse roles of CRIg in pathogen elimination, anti-microbial immunity and autoimmunity. In particular, we will explore how, through selective capturing by CRIg, an important balance is achieved between the immunological and clearance functions of liver and spleen. PMID- 29573979 TI - Incidentally detected atherosclerosis in the abdominal aorta or its major branches on computed tomography is highly associated with coronary heart disease in asymptomatic adults. AB - BACKGROUND: Atherosclerotic lesions in the abdominal aorta or its major branches are often incidentally detected on abdominal CT. However, clinical implications and optimal subsequent management are mostly left undetermined. METHODS: Consecutive, asymptomatic adults (age>=30) who underwent both abdominal CT and coronary computed tomography angiography as part of a self-referred health check up were investigated (n = 1494). RESULTS: Adjusted for cardiovascular risk factors, abdominal atherosclerotic lesions with stenosis<25% were associated with significant coronary stenosis, especially in the abdominal aorta (adjusted odds ratio [aOR] 3.37, 95% confidence interval [CI] 0.99-11.45) and any common iliac artery (aOR 2.99, 95% CI 1.43-6.26). The association was higher in atherosclerotic lesions with stenosis>=25%, respectively (aOR 16.39, 95% CI 4.00 67.11; aOR 7.32, 95% CI 2.84-18.86). Furthermore, any major abdominal artery stenosis added predictive value to significant coronary stenosis (area under the receiver operating curve: 0.7598 vs. 0.8019, P < 0.001). The extent of arterial territory involvement was associated with the presence of significant coronary stenoses (P for trend <0.001). CONCLUSION: Stenotic atherosclerotic lesions in the abdominal aorta or its major branches incidentally detected on abdominal CT are relatively prevalent and carry high risk for asymptomatic coronary arterial disease. PMID- 29573980 TI - Systemic effects of deep brain stimulation on synergic control in Parkinson's disease. AB - OBJECTIVE: We explored effects of deep brain stimulation (DBS) in patients with Parkinson's disease (PD) on the synergic control of fingers in a multi-finger force production task and of muscles in a task involving vertical posture. METHODS: The finger task involved the four fingers of a hand producing accurate total force followed by a targeted quick force pulse. The postural task involved releasing a load from extended arms. The analysis of synergies was performed within the framework of the uncontrolled manifold hypothesis. RESULTS: DBS led to no significant changes in indices of stability during steady-state phases. In contrast, DBS improved indices of agility, quantified as anticipatory synergy adjustments that reduced stability of salient performance variables in preparation to their quick change. There were moderate-to-strong correlations between indices of both stability and agility measured in the multi-finger force production and multi-muscle whole-body action. CONCLUSIONS: Our results point at systemic changes in synergic control in PD. They show that DBS is effective in improving only one components of synergic control related to agility in performance being relatively ineffective for the stability component. SIGNIFICANCE: The results show systemic brain mechanisms of synergies and suggest differential effects of DBS on indices of stability and agility. PMID- 29573981 TI - Hypoventilation Therapy Alleviates Panic by Repeated Induction of Dyspnea. AB - BACKGROUND: Previous research has shown that hypoventilation therapy reduces panic symptoms in part by increasing basal partial pressure of carbon dioxide (PCO2) levels. We tested an additional pathway by which hypoventilation therapy could exert its therapeutic effects: through repeated interoceptive exposure to sensations of dyspnea. METHODS: A total of 35 patients with panic disorder were trained to perform exercises to raise their end-tidal PCO2 levels using a portable capnometry device. Anxiety, dyspnea, end-tidal PCO2, and respiratory rate were assessed during each exercise across 4 weeks of training. Mixed-model analysis examined whether within-exercise levels of dyspnea were predictive of reduction of panicogenic cognitions. RESULTS: As expected, within-exercise anxiety and respiratory rate decreased over time. Unexpectedly, PCO2 dropped significantly from the beginning to the end of exercise, with these drops becoming progressively smaller across weeks. Dyspnea increased and remained consistently above basal levels across weeks. As hypothesized, greater dyspnea was related to significantly lower panicogenic cognitions over time even after controlling for anxiety and PCO2. Additional exploratory analyses showed that within-exercise increases in dyspnea were related to within-exercise increases in anxiety but were not related to within-exercise increases in PCO2. CONCLUSIONS: In support of the interoceptive exposure model, we found that greater dyspnea during hypoventilation exercises resulted in lower panicogenic cognitions even after the effect of PCO2 was taken into account. The findings offer an additional important target in panic treatment. PMID- 29573982 TI - Site-directed saturation mutagenesis of polyhydroxylalkanoate synthase for efficient microbial production of poly[(R)-2-hydroxybutyrate]. AB - In our previous study, artificial polyhydroxyalkanoate (PHA) poly[(R)-2 hydroxybutyrate] [P(2HB)] was successfully biosynthesized from racemic 2HB in recombinant Escherichia coli using an engineered PHA synthase, PhaC1Ps(S325T/Q481K). Although P(2HB) has promising material properties, the low level of polymer production was a drawback. In this study, we performed directed evolution of PhaC1Ps towards enhanced P(2HB) accumulation in E. coli by site directed dual saturation mutagenesis at the positions 477 and 481, which was known for their potential in enhancing natural PHA accumulation. By using a screening on agar plates with Nile red, eight colonies were isolated which produced a greater amount of P(2HB) compared to a colony expressing the parent enzyme PhaC1Ps(S325T/Q481K). Among them, the cells expressing PhaC1Ps(S325T/S477R/Q481G) [ST/SR/QG] accumulated polymer at the highest level (up to 2.9-fold). As seen in PhaC1Ps(ST/SR/QG), glycine and basic amino acid residues (K or R) were frequently found at the two positions of the select mutated enzymes. The enzymatic activity of PhaC1Ps(ST/SR/QG) toward 2HB-CoA was approximately 3-fold higher than that of the parent enzyme. Additionally, expression levels of the select mutated enzymes were lower than the parent. These results indicated that PhaC1Ps mutagenesis at the positions 477 and 481 increased specific activity toward 2HB-CoA and it could result in the enhanced production of P(2HB). PMID- 29573983 TI - Isolation and identification of Penicillium chrysogenum strain Y5 and its copper extraction characterization from waste printed circuit boards. AB - Biohydrometallurgy is generally considered as a green technology for the recycling of industrial solid waste. In this study, an indigenous fungal strain named Y5 with the ability of high-yielding organic acids was isolated and applied in bioleaching of waste printed circuit boards (PCBs). The strain Y5 was identified as Penicillium chrysogenum by morphological and molecular identification. Meanwhile, we investigated that an optimal set of culturing conditions for the fungal growth and acids secretion was 15 g/L glucose with initial pH 5.0, temperature 25 degrees C and shaking speed 120 rpm in shaken flasks culture. Moreover, three bioleaching processes such as one-step, two-step and spent medium processes were conducted to extract copper from waste PCBs. Spent medium bioleaching showed higher copper extraction percentage and it was 47% under 5%(w/v) pulp density. Transmission electron microscope (TEM) observation combining with energy dispersive analysis of X-rays (EDAX) showed that the leached metal ions did not obviously damage the hypha cells. All above results indicated that P.chrysogenum strain Y5 has the tolerance to metal ions, suggesting its potential in recycling of metals from waste PCBs in industry. PMID- 29573984 TI - Electromyographic analysis of balance exercises in single-leg stance using different instability modalities of the forefoot and rearfoot. AB - PURPOSE: To investigate the activity of lower extremity muscles in response to single-leg stance on a training device, destabilizing the forefoot while the rearfoot stands on a fixed plate and vice versa compared with a balance pad and the floor. DESIGN: Cross-sectional study. SETTING: University's laboratory. PARTICIPANTS: Twenty-seven healthy adults. METHODS: Surface electromyography and 2D video analysis were used to record the activity of lower extremity muscles and to control sagittal knee joint angle during single-leg stance trials under one stable control condition and five unstable conditions. RESULTS: The majority of lower extremity muscles were significantly more active when the forefoot was destabilized while the rearfoot remained stable compared with the stable condition and the conditions where the forefoot was stable and the rearfoot unstable (p <0 .001). Mean change of knee joint angle was significantly increased under the conditions rearfoot stable/forefoot unstable (p = 0.001). The soleus muscle activation was significantly increased when balancing on the balance pad (p < 0.001). CONCLUSIONS: Increased activity in the majority of lower extremity muscles and sagittal knee joint angles indicate that destabilizing the forefoot while the rearfoot remains stable is the most challenging balance task. Soleus muscle activation increased when performing ankle plantarflexion on the soft balance pad. PMID- 29573985 TI - Accommodation and age-dependent eye model based on in vivo measurements. AB - PURPOSE: To develop a flexible model of the average eye that incorporates changes with age and accommodation in all optical parameters, including entrance pupil diameter, under photopic, natural, environmental conditions. METHODS: We collated retrospective in vivo measurements of all optical parameters, including entrance pupil diameter. Ray-tracing was used to calculate the wavefront aberrations of the eye model as a function of age, stimulus vergence and pupil diameter. These aberrations were used to calculate objective refraction using paraxial curvature matching. This was also done for several stimulus positions to calculate the accommodation response/stimulus curve. RESULTS: The model predicts a hyperopic change in distance refraction as the eye ages (+0.22D every 10 years) between 20 and 65 years. The slope of the accommodation response/stimulus curve was 0.72 for a 25 years-old subject, with little change between 20 and 45 years. A trend to a more negative value of primary spherical aberration as the eye accommodates is predicted for all ages (20-50 years). When accommodation is relaxed, a slight increase in primary spherical aberration (0.008MUm every 10 years) between 20 and 65 years is predicted, for an age-dependent entrance pupil diameter ranging between 3.58mm (20 years) and 3.05mm (65 years). Results match reasonably well with studies performed in real eyes, except that spherical aberration is systematically slightly negative as compared with the practical data. CONCLUSIONS: The proposed eye model is able to predict changes in objective refraction and accommodation response. It has the potential to be a useful design and testing tool for devices (e.g. intraocular lenses or contact lenses) designed to correct the eye's optical errors. PMID- 29573986 TI - Can a collaborative healthcare network improve the care of people with epilepsy? AB - New opportunities are now available to improve care in ways not possible previously. Information contained in electronic medical records can now be shared without identifying patients. With network collaboration, large numbers of medical records can be searched to identify patients most like the one whose complex medical situation challenges the physician. The clinical effectiveness of different treatment strategies can be assessed rapidly to help the clinician decide on the best treatment for this patient. Other capabilities from different components of the network can prompt the recognition of what is the best available option and encourage the sharing of information about programs and electronic tools. Difficulties related to privacy, harmonization, integration, and costs are expected, but these are currently being addressed successfully by groups of organizations led by those who recognize the benefits. PMID- 29573987 TI - Utilizing Coarse-Grained Modeling and Monte Carlo Simulations to Evaluate the Conformational Ensemble of Intrinsically Disordered Proteins and Regions. AB - In this study, we have used the coarse-grained model developed for the intrinsically disordered saliva protein (IDP) Histatin 5, on an experimental selection of monomeric IDPs, and we show that the model is generally applicable when electrostatic interactions dominate the intra-molecular interactions. Experimental and theoretically calculated small-angle X-ray scattering data are presented in the form of Kratky plots, and discussions are made with respect to polymer theory and the self-avoiding walk model. Furthermore, the impact of electrostatic interactions is shown and related to estimations of the conformational ensembles obtained from computer simulations and "Flexible meccano." Special attention is given to the form factor and how it is affected by the salt concentration, as well as the approximation of using the form factor obtained under physiological conditions to obtain the structure factor. PMID- 29573988 TI - Structural Insights into the Induced-fit Inhibition of Fascin by a Small-Molecule Inhibitor. AB - Tumor metastasis is responsible for ~90% of all cancer deaths. One of the key steps of tumor metastasis is tumor cell migration and invasion. Filopodia are cell surface extensions that are critical for tumor cell migration. Fascin protein is the main actin-bundling protein in filopodia. Small-molecule fascin inhibitors block tumor cell migration, invasion, and metastasis. Here we present the structural basis for the mechanism of action of these small-molecule fascin inhibitors. X-ray crystal structural analysis of a complex of fascin and a fascin inhibitor shows that binding of the fascin inhibitor to the hydrophobic cleft between the domains 1 and 2 of fascin induces a ~35o rotation of domain 1, leading to the distortion of both the actin-binding sites 1 and 2 on fascin. Furthermore, the crystal structures of an inhibitor alone indicate that the conformations of the small-molecule inhibitors are dynamic. Mutations of the inhibitor-interacting residues decrease the sensitivity of fascin to the inhibitors. Our studies provide structural insights into the molecular mechanism of fascin protein function as well as the action of small-molecule fascin inhibitors. PMID- 29573990 TI - Apoptosis and eryptosis: Striking differences on biomembrane level. AB - The cell plasma membrane plays an essential role in programmed cell death of nucleated cells (apoptosis) and erythrocytes (eryptosis), and its changes due to loss of transmembrane asymmetry are quite similar. However, nucleated cells possess the network of intracellular membranes, which are missing in erythrocytes. Providing comparative studies with series of molecular probes, we observe dramatic differences in membrane lipid order in the course of apoptosis and eryptosis. In contrast to nucleated cells, in which a significant drop of the lipid order in the plasma membrane is observed, the erythrocyte membrane retains the relatively high level of the lipid order. Observation in nucleated cells of significant differences between inner and plasma membranes and detection of apoptotic bodies with different organization suggest that the decrease in the lipid order of their plasma membrane could be at least partially explained by the phospholipid and/or cholesterol exchange between membranes. Such features are absent in erythrocytes. PMID- 29573989 TI - Short-interval intracortical inhibition: Comparison between conventional and threshold-tracking techniques. AB - BACKGROUND: Short-interval intracortical inhibition (SICI) is conventionally measured as the relative amplitude reduction of motor evoked potentials (MEPs) by subthreshold conditioning stimuli. In threshold-tracking SICI (T-SICI), stimulus intensity is instead adjusted repeatedly to maintain a constant MEP and inhibition is measured as the relative threshold increase. T-SICI is emerging as a useful diagnostic test, but its relationship to conventional amplitude SICI (A SICI) is unclear. OBJECTIVE: To compare T-SICI and its reliability with conventional A-SICI measurements. METHODS: In twelve healthy volunteers (6 men, median age 30 years), conventional and T-SICI were recorded at conditioning stimuli (CS) of 50-80% resting motor threshold (RMT) and interstimulus interval of 2.5 ms. Measurements were repeated on the same day and at least a week later by a single operator. RESULTS: Across the CS range, mean group T-SICI showed a strong linear relationship to the mean group values measured by conventional technique (y = 29.7-0.3x, R2 = 0.99), but there was considerable interindividual variability. At CS 60-80% RMT, T-SICI had excellent intraday (intraclass correlation coefficient, ICC, 0.81-0.92) and adequate-to-excellent interday (ICC 0.61-0.88) reproducibility. Conventional SICI took longer to complete (median of 5.8 vs 3.8 min, p < 0.001) and tended to have poorer reproducibility (ICC 0.17 0.42 intraday, 0.37-0.51 interday). With T-SICI, smaller sample sizes were calculated for equally powered interventional studies. CONCLUSION: The close relationship between conventional and T-SICI suggests that both techniques reflect similar cortical inhibitory mechanisms. Threshold-tracking measurements of SICI may be able to improve reproducibility, to shorten acquisition time and to reduce sample sizes for interventional studies compared with the conventional technique.

Lipoprotein N-acyl transferase (Lnt) catalyzes the final step in the lipoprotein posttranslational processing pathway. The mature lipoprotein can remain in the inner membrane or be trafficked to the outer membrane in the case of diderm prokaryotes. With a view to obtaining high-resolution crystal structures of membrane integral Lnt for use in drug discovery a program was undertaken to generate milligram quantities of stable, homogenous and functional protein. This involved screening across bacterial species for suitable orthologues and optimization at the level of protein expression, solubilization and stability. Combining biophysical and functional characterization, orthologous Lnt from Escherichia coli and the opportunistic human pathogen Pseudomonas aeruginosa was identified as suitable for the proposed structure determination campaign that ultimately yielded crystal structures. The rational approaches taken that eventually provided structure quality protein are presented in this report.

AB - Tail fan necrosis (TFN) is the bacterial infection of the tail fan of spiny lobsters which leads to melanosis and erosion of the tail fan tissues. The condition is commonly found among spiny lobsters in aquaculture and commercial fisheries, and greatly reduces their commercial value. This study describes the pathology of TFN by examining the tail fans (telson, uropods) and internal organs (mid-gut, hepatopancreas, heart and gill) of 29 affected wild spiny lobsters (Jasus edwardsii) and 14 unaffected in New Zealand. Initial signs of TFN were observed around the margins of lacerations to the tail fan, with more extensive signs extending from these presumptive sites of initiation. The establishment of the condition at points of injury is consistent with the penetration of TFN through the cuticle and tissue layers of the affected tail fans, which is rarely seen in other forms of shell disease. Entry into these tissues was characterised initially by caseous necrosis and haemocyte accumulation, followed by the spread of these responses together with melanisation. Additional pathological changes to the tail fans included pseudomembrane formation, detachment of epidermis or cuticle, clotted haemolymph and fibrosis. Among internal organs, pathological changes were found in a total of two mid-gut, four heart and two gill samples from eight lobsters with TFN, while no suspected changes were found in the organs of lobsters without TFN. The causes of internal organ pathology associated with TFN in spiny lobsters warrants more detailed research.

AB - Covert mortality nodavirus (CMNV) is the pathogen that has been identified as the cause of viral covert mortality disease (VCMD) in marine and brackish water shrimp. Recent outbreaks of this disease have resulted, and continue to result, in substantial production and economic losses to shrimp aquaculture producers in China and elsewhere. To explore potential vectors and reservoir hosts of CMNV, we collected fifteen species of invertebrates from shrimp ponds affected by VCMD. Samples were tested through the use of: reverse transcription loop-mediated isothermal amplification (RT-LAMP), reverse transcription nested PCR (RT-nPCR) followed by gene sequencing, histopathology, and in situ RNA hybridization (ISH). The results of RT-LAMP and RT-nPCR assay indicated that CMNV positive samples were identified in eleven species including brine shrimp Artemia sinica, a barnacle Balanus sp., the rotifer Brachionus urceus, the amphipod Corophium sinense Zhang, the Pacific oyster Crassostrea gigas, a hermit crab Diogenes edwardsii, the common clam Meretrix lusoria, a ghost crab Ocypode cordimundus, the hyperiid amphipod Parathemisto gaudichaudi, a fiddler crab Tubuca arcuata, and an unidentified gammarid amphipod. The alignment of CMNV RNA-dependent RNA polymerase gene sequences from eight of the species demonstrated high identities (97-100% in nucleotide sequence) with that from the original CMNV isolates of Penaeus vannamei, which suggests that these species could either be infected with, or acting as mechanical vectors of, CMNV. The CMNV infection in C. sinense, D. edwardsii, O. cordimanus Zhang, P. gaudichalldi, and T. arcuata results, to varying degrees, in vacuolation and necrosis of targeted tissues, as was verified by ISH. The infection of CMNV in these five species suggests that they might act as reservoir hosts of CMNV. The results indicate that the common species of invertebrates inhabiting shrimp ponds may constitute biological risk factors for CMNV outbreaks. PMID- 29573995 TI - Investigation of ventricular pre-excitation electrocardiographic pattern in two horses: clinical presentation and potential causes. AB - Two horses referred to the Unitat Equina, Fundacio Hospital Clinic Veterinari, Universitat Autonoma de Barcelona, for unrelated clinical problems, and with no previous history of cardiac disease exhibited an intermittent ventricular pre excitation electrocardiographic pattern during hospitalization. Both animals showed decreased plasma total and ionized magnesium concentrations, but no other relevant electrolyte disturbances were detected. Altered interventricular septal motion associated with ventricular pre-excitation beats (VPBs) was detected on M mode echocardiography in both horses. The likely localization of an accessory pathway (AP) was identified in case 2 using pulsed-wave tissue Doppler imaging in the left anterior paraseptal location. Decreased frequency of the VPB was observed with long-term magnesium supplementation and restoration of plasma magnesium concentrations. The presence of ventricular pre-excitation electrocardiographic pattern was attributed to higher sensitivity of the AP to hypomagnesemia in both cases. PMID- 29573996 TI - From melody to words: The role of sex hormones in early language development. AB - Contribution to Special Issue on Fast effects of steroids. Human infants are the most proficient of the few vocal learner species. Sharing similar principles in terms of the generation and modification of complex sounds, cross-vocal learner comparisons are a suitable strategy when it comes to better understanding the evolution and mechanisms of auditory-vocal learning in human infants. This approach will also help us to understand sex differences in relation to vocal development towards language, the underlying brain mechanisms thereof and sex specific hormonal effects. Although we are still far from being capable of discovering the "fast effects of steroids" in human infants, we have identified that peripheral hormones (blood serum) are important regulators of vocal behaviour towards language during a transitory hormone surge ("mini-puberty") that is comparable in its extent to puberty. This new area of research in human infants provides a promising opportunity to not only better understand early language acquisition from an ontogenetic and phylogenetic perspective, but to also identify reliable clinical risk-markers in infants for the development of later language disorders. PMID- 29573997 TI - The use of tDCS as a therapeutic option for tinnitus: a systematic review. AB - INTRODUCTION: Due to the subjectivity of the tinnitus diagnosis and its diverse etiologies, establishing an effective treatment is complex. In this context, transcranial direct current stimulation, a noninvasive option, is available for most patients and has shown good results in the treatment of other symptoms such as chronic pain. OBJECTIVE: To evaluate the therapeutic response of tinnitus to transcranial direct current stimulation. METHODS: A systematic review of the literature was performed using the following descriptors: tinnitus, transcranial direct current stimulation and randomized clinical trial. The research was carried out in the MEDLINE/PUBMED, Lilacs, and Scielo databases. The inclusion criteria were: patients over 18 years of age with no associated comorbidities, who had a diagnosis established by a specialist or through the application of previously validated scales and criteria applied by a non-specialist physician. RESULTS: A total of 4165 studies were found, and a total of six were selected after the inclusion criteria were applied, obtaining a sample of 602 patients. Based on the defined criteria, there was a positive response to transcranial direct current stimulation in 14.86% of the participants. CONCLUSION: Based on literature studied, there is no therapeutic response of tinnitus to transcranial direct current stimulation. PMID- 29573998 TI - Painless bilateral bullous keratopathy. AB - Bullous keratopathy is a pathological corneal condition that arises due to irreversible oedema associated with endothelial cell loss or dysfunction. Symptoms may vary from mild (transient blurred vision and increased glare from epithelial oedema) to severe (an acute and significant loss of vision associated with frank endothelial decompensation, and pain due to ruptured epithelial bullae). Possible treatments to restore vision and minimise pain include topical hypertonic agents, bandage contact lenses, superficial anterior corneal surgical procedures or penetrating full thickness or endothelial keratoplasty. This case report describes a rare presentation of painless, bilateral, asymmetric bullous keratopathy with severe vision loss in an elderly male with non-insulin dependent diabetes mellitus. PMID- 29573999 TI - Toxocara spp. infection and risk of childhood asthma: A systematic review and meta-analysis. AB - Asthma is one of the most common chronic respiratory disease worldwide, with a negative impact on quality of life and socio-economic status of patients. There are some evidences to suggest that Toxocara infection is a neglected risk factor for childhood asthma. We performed a systematic review and meta-analysis to further understanding of this relationship. Five databases include PubMed, Science Direct, Scopus, Web of Science (ISI), and Google scholar were searched (up to October 2017) to identify the relevant studies. We used random-effects meta-analysis model to estimate the pooled odds ratio (OR) and 95% confidence intervals (CI). Heterogeneity was assessed with the Q-test and I2 statistic. A total of 17 studies including 11 studies with case-control design (1139 patients and 1023 controls) and six studies with cross-sectional design (a total of 5469 participants, 872 asthmatics, and 4597 non-asthmatics children) met the eligibility criteria. An increased risk for asthma was observed in children with Toxocara infection seropositivity (OR, 1.91; 95% CI, 1.47-2.47). In sub-group analysis, the pooled ORs were (OR, 2.13; 95% CI, 1.43-3.15) and (OR, 1.73; 95% CI, 1.23-2.44) for case-control and cross-sectional studies, respectively. Moreover, considering to specific IgE seropositivity, a pooled OR of 2.36 (95% CI, 0.93-5.98) was observed. In conclusion, this meta-analysis revealed that children infected with Toxocara spp. are more likely to have asthma compared to non-infected children. More studies (especially longitudinal studies) are needed to further investigate the impact of Toxocara spp. infection on the onset or development of asthma. PMID- 29574000 TI - Invasive Pomacea snails as important intermediate hosts of Angiostrongylus cantonensis in Laos, Cambodia and Vietnam: Implications for outbreaks of eosinophilic meningitis. AB - The rat lungworm Angiostrongylus cantonensis causes human eosinophilic meningitis and it is endemic in Southeast Asia, but little is known about its distribution in Laos, Cambodia and Vietnam. We conducted a multi-country survey for A. cantonensis in these countries to estimate its prevalence in snails along the Mekong River and the east coast of Vietnam. We identified Angiostrongylus species by morphological and molecular analysis. We found A. cantonensis in the invasive snail, Pomacea spp. The wide accessibility of Pomacea snails, along with their infection by A. cantonensis, indicates that this snail species could be used in surveillance for preventing outbreaks of eosinophilic meningitis. PMID- 29574001 TI - Expression and biochemical characterization of alpha-ketoglutarate decarboxylase from cyanobacterium Synechococcus sp. PCC7002. AB - alpha-Ketoglutarate decarboxylase (alpha-KGD), one member of alpha-keto acid decarboxylases, catalyzing non-oxidative decarboxylation of alpha-ketoglutarate to form succinic semialdehyde, was proposed to play critical role in completing tricarboxylic acid (TCA) cycle of cyanobacteria. Although the catalytic function of alpha-KGD from Synechococcus sp. PCC7002 was demonstrated previously, there was no detailed biochemical characterization of alpha-KGD from Synechococcus sp. PCC7002 yet. In this study, the gene encoding alpha-KGD from Synechococcus sp. PCC7002 was amplified and soluble expression of recombinant alpha-KGD was achieved by coexpressing with pTf16 chaperone plasmid in E. coli BL21 (DE3). Kinetic analysis showed that the activity of alpha-KGD was dependent on cofactors of thiamine pyrophosphate and divalent cation. Meanwhile this alpha-KGD was specific for alpha-ketoglutarate with respect to the decarboxylation activity despite of the pretty low activity of acetolactate synthase. The catalytic efficiency of alpha-KGD (the values of kcat and kcat/Km for alpha-ketoglutarate were 1.2s-1 and 6.3*103M-1s-1, respectively) might provide evidence for its physiological role in TCA cycle of Synechococcus sp. PCC7002. PMID- 29574002 TI - Treatment With JAK Inhibitors in Myelofibrosis Patients Nullifies the Prognostic Impact of Unfavorable Cytogenetics. AB - INTRODUCTION: In the era before Janus kinase (JAK) inhibitors, cytogenetic information was used to predict survival in myelofibrosis patients. However, the prognostic value of cytogenetics in the setting of JAK inhibitor therapy remains unknown. PATIENTS AND METHODS: We performed a retrospective analysis of 180 patients with bone marrow biopsy-proven myelofibrosis from 3 US academic medical centers. We fit Cox proportional hazards models for overall survival and transformation-free survival on the bases of 3 factors: JAK inhibitor therapy as a time-dependent covariate, dichotomized cytogenetic status (favorable vs. unfavorable), and statistical interaction between the two. The median follow-up time was 37.1 months. RESULTS: Among patients treated with best available therapy, unfavorable cytogenetic status was associated with decreased survival (hazard ratio = 2.31; P = .025). At initiation of JAK inhibitor therapy, unfavorable cytogenetics was (nonsignificantly) associated with increased survival compared to favorable cytogenetics (hazard ratio = 0.292; P = .172). The ratio of hazard ratios was 0.126 (P = .034). These findings were similar after adjusting for standard clinical prognostic factors as well as when measured against transformation-free survival. CONCLUSION: The initiation of JAK inhibitor therapy appears to change the association between cytogenetics and overall survival. There was little difference in survival between treatment types in patients with favorable cytogenetics. However, the use of JAK inhibitor therapy among patients with unfavorable cytogenetics was not associated with worse survival compared to favorable cytogenetics. Our analyses suggest that initiation of JAK inhibitor therapy nullifies the negative prognostic implication of unfavorable cytogenetics established in the pre-JAK inhibitor therapy era. PMID- 29574003 TI - CD105 maintains the thermogenic program of beige adipocytes by regulating Smad2 signaling. AB - Beige adipocytes are thermogenic adipocytes with developmental and anatomical properties distinct from those of classical brown adipocytes. Recent studies have revealed several key molecular regulators of beige adipocyte development. CD105, also called endoglin, is a membrane protein composed of TGF-beta receptor complex. It regulates TGF-beta-family signal transduction and vascular formation in vivo. We report here that CD105 maintains the thermogenic gene program of beige adipocytes by regulating Smad2 signaling. Cd105-/- adipocyte precursors showed augmented Smad2 activation and decreased expression of thermogenic genes such as Ucp1 and Prdm16-which encodes a transcriptional regulatory protein for thermogenesis-after adipogenic differentiation. Smad2 signaling augmentation by the constitutively active form of Smad2 decreased the expression of thermogenic genes in beige adipocytes. Loss of thermogenic activity in Cd105-/- beige adipocytes was rescued by Prdm16 expression. These data reveal a novel function of CD105 in beige adipocytes: maintaining their thermogenic program by regulating Smad2 signaling. PMID- 29574004 TI - A multi-screening Fast qPCR approach to the identification of abortive agents in ruminants. AB - Abortion in ruminants represents an important economic concern for farmers. Microbial agents, such as Brucella spp., Chlamydia spp., Coxiella burnetii, Leptospira spp., Neospora caninum, Salmonella spp. and Toxoplasma gondii, are among the main infectious causes of abortion and require rapid and reliable diagnosis. This study describes the development of a multi-screening assay using Fast Real-Time PCR (Fast qPCR) that allows, in a single test, the simultaneous identification of the above-mentioned abortive agents. This multi-screening approach is characterized by a mean diagnostic sensitivity and specificity of 100% and 97%, respectively; it has a limit of detection (LOD) ranging from 5 * 103 to 4 * 104 genomic copies/g of tissue and a very good concordance with traditional end-point PCR assays used in routine diagnostic activity. The proposed method represents a rapid approach to the simultaneous detection of the main abortive agents in ruminants that allows to make an accurate diagnosis and to set up appropriate control measures in a short period of time. PMID- 29574005 TI - Prevalence and risk factors associated with chronic kidney disease in adults living in 3 different altitude regions in the Tibetan Plateau. AB - BACKGROUND: Living at high altitude may have undesirable effects on the kidney. We explored the chronic kidney disease (CKD) prevalence and risk factors among the residents living at different altitude in Tibetan Plateau. METHODS: A cross sectional study was carried out in 2014 to 2016 in Linzhi (2900 m altitude), Lhasa (3650 m) and Anduo (4700 m). Information on the cardiovascular risk factors was collected and blood and urine samples were measured. RESULTS: The data of 1707 subjects aged >=35 y were analyzed. The age-standardized prevalence of CKD in Linzhi, Lhasa and Anduo was 27.7% (95% CI: 22.1-33.3%), 18.3% (12.7-24.0%) and 30.4% (23.5-37.3%) in men and 37.7% (31.8-43.6%), 29.5% (24.6-34.4%) and 36.7% (29.0-44.4%) in women, respectively. Multivariable logistic regression showed that age, female gender, systolic blood pressure, fasting serum glucose, with primary school education or lower were associated with higher risk of CKD and living in Lhasa was associated with lower risk of CKD. CONCLUSION: A higher prevalence of CKD was found in the residents living in the Tibetan Plateau. However, for the highlanders living at higher altitude does not mean higher risk. The CKD risk factors found in this study are similar to those in other studies. PMID- 29574006 TI - A rapid screening of a recurrent CYP24A1 pathogenic variant opens the way to molecular testing for Idiopathic Infantile Hypercalcemia (IIH). AB - INTRODUCTION: Loss-of-function mutations in cytochrome P450 family 24 subfamily A member 1 (CYP24A1) gene are associated with Idiopathic Infantile Hypercalcemia (IIH) and adult kidney stone disease. The enzyme deficiency leads to an impaired vitamin D catabolism pathway, resulting in a syndrome characterized by recurrent hypercalcemia, hypercalciuria and suppressed parathyroid hormone (PTH) levels. In these patients, the genetic evaluation of CYP24A1 is an important diagnostic tool, allowing the definitive diagnosis of IIH. METHODS: A rapid CYP24A1 gene testing based on High Resolution Melting Analysis (HRMA) was designed in order to detect the CYP24A1 c.428_430delAAG (p.Glu143del), a recurrent IIH-associated variant. RESULTS: HRMA method was able to identify c.428_430delAAG genotypes evaluating melting curve shape and melting temperature (Tm). Heterozygous samples exhibited a typical melting profile while homozygous samples showed a specific Tm shift. CONCLUSIONS: We provide evidence about application of HRMA in unambiguous genotyping of the CYP24A1 c.428_430delAAG variant, making this method useful in clinical molecular diagnostics. This approach opens the way to a helpful molecular analysis of CYP24A1 gene in IIH diagnosis, to an improved pharmacological treatment strategy and to a reduced risk of recurrent stones and worsening nephrocalcinosis. PMID- 29574007 TI - A systematic review on risk factors associated with sepsis in patients admitted to intensive care units. AB - OBJECTIVE: We sought to systematically review data on the risk factors influencing the incidence of sepsis in patients admitted to intensive care units (ICUs). REVIEW METHODS: An electronic search was undertaken in PubMed, MEDLINE, Scopus, and the Cochrane Library for studies reporting the risk factors of sepsis from the earliest available date up to December 30, 2016. RESULTS: Among the 2978 articles, 14 studies met the inclusion criteria with a total of 56 164 participants from nine countries. The extracted risk factors were from the following categories: demographic, critical care interventions, surgery-related factors, pre-existing comorbidities, severity of organ injury, and biomarkers and biochemical and molecular indicators. From demographic factors, older age and male gender were associated with an increased risk of sepsis among ICU-admitted patients. CONCLUSION: Our analysis comprehensively summarised the risk factors of sepsis in patients admitted to medical, surgical, neurologic, trauma, and general ICUs. Age, sex, and comorbidities were non-modifiable risk factors; however, critical care interventions and surgery-related factors were modifiable factors and suggest that improving the care of surgical patients and effective management of critical care interventions may play a key role in decreasing the development of sepsis in patients admitted to the ICUs. PMID- 29574008 TI - [Prostate cancer screening using prostate-specific antigen: The views of general and laboratory physicians]. AB - INTRODUCTION: It is currently recommended to provide individualised information on benefit-risk balance and shared decision-making in prostate cancer screening using prostate-specific antigen (PSA). AIM: To determine the usual practice and the views of general and laboratory practitioners in the screening of prostate cancer using PSA. MATERIAL AND METHODS: A cross-sectional study based on a questionnaire and on PSA screening requests from Primary Health Care (PHC) in men older than 49 years with no prostatic symptoms. RESULTS: In 2015, PHC in Catalonia requested PSA on 15.2% of males. A total of 114 general practitioners and 227 laboratory practitioners participated in the questionnaire. The mean age of those who responded was 43 years with a mean of 17 years' experience, and included 64% women. According to general practitioners, 61% of PSA was performed at the patient's request. The uncertainty score when requesting PSA was 5 points for general practitioners and 5.7 for laboratory professionals. Interest in having clinical recommendations received 7.2 points in PHC, and 8.8 in the laboratory. Knowledge about the different clinical practice guidelines received was less than 5 points overall. CONCLUSIONS: General practitioners requested PSA screening in almost one-sixth of men over the age of 49 without prostate disease, often at the patient's request, and after informing them of the benefits and risks. PHC and laboratory physicians were interested in having recommendations and information, although they did not usually consult clinical practice guidelines immediately. PMID- 29574009 TI - [Epidemiology and management of community acquired pneumonia: more than 10 years experience]. AB - OBJECTIVE: To describe the characteristics of patients diagnosed with Community Acquired Pneumonia in this basic health area, their management, outcomes, and use of prognostic scales driven by the few studies carried out from Primary Care on these aspects. MATERIAL AND METHODS: Descriptive cross-sectional study on a population diagnosed with Community Acquired Pneumonia if three urban health centres, during the period January 2000 to 31 July 2103. RESULTS: Out of a sample of 1,290 patients obtained, 56.1% were men, and the mean age of the population was 61.9 years. There were 22.7% smokers. More than half (59.9%) had a disease in the prognostic scales, with Diabetes Mellitus present in 20%, and 36.1% with pulmonary disease (17.6% COPD, 11.8% asthma). Just under half (43.2%) of the total patients were diagnosed in Primary Care. There was a diagnostic X-ray in 92.7% of the cases, and a follow-up X-ray in 59.4%. Prognostic scales were recorded in 2% of the cases. The most commonly used antibiotics were amoxicillin clavulanic (30.7%) and levofloxacin (30.4%). Having prior disease increases the risk of re-treatment by 1.6 (95% CI; 1.1-2.2)]. The mortality risk is multiplied by 5.3 on having a previous disease (95% CI; 1.3-19.2). CONCLUSIONS: In the Primary Care setting, Community Acquired Pneumonia is a common and potentially serious disease which, in half the cases, occurs in patients with associated comorbidity. As regards treatment and management, is highlighted the wide use made of amoxicillin-clavulanic, compared to the low use of amoxicillin, combined therapy, and prognostic scales. PMID- 29574010 TI - Noradrenergic effects on olfactory perception and learning. AB - We here review modulation of olfactory guided behavioral tasks by noradrenaline. In this review we focus on modulation of the main olfactory system in adult rodents. We detail behavioral paradigms commonly used and discuss how sensory perception and learning can be measured using these paradigms. We then describe neuromodulatory effects on several aspects of olfactory processing, including detection and encoding. We describe how memory duration, specificity and duration are affected by noradrenergic modulation. PMID- 29574011 TI - Residue of insecticides in foodstuff and dietary exposure assessment of Brazilian citizens. AB - The goal of this work is to study the presence of 17 different pyrethroids and chlorpyrifos in animal origin food samples, including chicken, beef, fish, eggs and milk. The samples were analyzed by GC/NCI-MS/MS in order to determine their insecticide concentration levels, the relation between the amount of insecticides and the lipid content, as well as their isomeric composition. Bifenthrin, cypermethrin, cyhalothrin, permethrin, deltamethrin and chlorpyrifos have been detected in real samples. The highest levels find were verified for chlorpyrifos (45.7 MUg L-1, 17.5 MUg kg-1 ww) and cypermethrin (2.75 MUg L-1, 14.7 MUg kg-1 ww) in milk and beef, respectively. The estimate of daily intake showed that none of these insecticides exceeded the safety limits of the acceptable daily intake values. A strong correlation between the amount of pesticides and lipid content was found for beef, fish and chicken samples. Regarding the isomers, a predominance of cis isomers in samples contaminated with cypermethrin was verified. PMID- 29574012 TI - Protection of cyanidin-3-O-glucoside against acrylamide- and glycidamide-induced reproductive toxicity in leydig cells. AB - Acrylamide (AA) occurs in many cooked carbohydrate-rich foods and has caused widespread concern as a possible carcinogen. Glycidamide (GA) is the ultimate genotoxic metabolite of AA. The present study was to investigate the protective effect of Cyanidin-3-O-glucoside (C3G) against AA- and GA-induced reproductive toxicity in R2C Leydig cells. The results demonstrated that C3G inhibited AA- and GA-induced cytotoxicity and mitochondria-mediated cell apoptosis, the effective doses of C3G were ranging from 10 to 50 MUM. Besides, AA (1.925 mM) and GA (0.872 mM) exposure increased ROS level and decreased mitochondrial membrane potential, which led to a decrease in progesterone production, while C3G ranging from 10 to 50 MUM reduced ROS immediately, and increased progesterone production after 24 h treatment. Furthermore, C3G up-regulated expression of Bcl-2 protein and down regulated pro-apoptotic protein Bax and cleaved Caspase-3 after 24 h treatment in 1.925 mM AA- and 0.872 mM GA-treated R2C cells. Moreover, C3G intervention increased the protein expression of steroidogenic acute regulatory (StAR). It was concluded that C3G is effective in reducing AA- and GA-induced reproductive toxicity via inhibition of ROS generation, mitochondrial membrane depolarization and apoptosis, as well as activating steroidogenic enzymes.

AB - AIMS: We investigated the reproducibility of creating a vascularized tissue flap in an in vivo tissue engineering chamber by incubating a vascular pedicle imbedded in a collagen sponge with activated platelet-rich plasma (aPRP) and basic fibroblast growth factor (bFGF). METHODS: Collagen sponge soaked with saline (control group), bFGF (Group 1), aPRP (Group 2), and aPRP/controlled release bFGF (Group 3) was implanted with a saphenous arteriovenous pedicle into a tissue engineering chamber, located subcutaneously in the groin of rabbits. After 4 weeks of implantation, the contents in the chamber were harvested for volumetric and histological analyses. RESULTS: The total volume of generated tissue in Group 3 was the largest among the Groups (control group vs. Group 3, p < 0.01). The volume of the pedicle vascular bundle/adipose tissue component was larger in Groups 1 and 3 than that in the control group (p < 0.05 and p < 0.01, respectively). The inflammatory tissue volume was larger in Groups 2 and 3 (control group vs. Group 3, p < 0.05). In a smaller long-term study, inflammatory tissue at 4 weeks was gradually replaced by the adipose tissue within 8 weeks. CONCLUSION: PRP-induced inflammatory reactions were considered to be necessary to stimulate cell migration into the chamber, leading to more tissue regeneration with abundant cell components. We conclude that PRP contributes to the reproducibility of preparing vascularized flaps in an in vivo chamber.

PMID- 29574017 TI - What Makes a Good Endoscopic Teacher: A Qualitative Analysis. AB - OBJECTIVE: Teaching learners to perform endoscopic procedures is challenging, yet effective endoscopy teaching practices are not well-described in the literature, and prior studies have focused on perspectives of supervising physicians rather than learners. We sought to characterize, from the perspective of endoscopy learners, endoscopic teaching behaviors perceived as beneficial and detrimental to learning using qualitative methods. DESIGN: This is a prospective qualitative content analysis. Gastroenterology fellows from 2 tertiary care centers anonymously provided feedback regarding supervising physicians' teaching behaviors during endoscopic training between March 2016 and December 2016. Preprinted cards were completed at the conclusion of procedures to document behaviors that fellows perceived as enhancing or hampering their learning. Two investigators performed content analysis of written comments; each identified behavior was assigned positive or negative valence. SETTING: Mount Sinai Hospital in New York, New York and University of California San Francisco in San Francisco, California. Both institutions are academic tertiary care centers. PARTICIPANTS: A total of 19 gastroenterology fellows at 2 training institutions participated. RESULTS: A total of 239 teaching behaviors were identified by 19 fellows who worked with 31 supervising physicians; 29 unique behaviors were identified and organized into 7 themes: teaching, learning environment, autonomy, communication, coaching, feedback, and professionalism. Of all, 185 (77.4%) behaviors were reported as beneficial, and 54 (22.6%) as detrimental to the learning experience. Behaviors related to teaching were most often perceived as beneficial, while behaviors related to professionalism and communication were most often perceived as detrimental to learning. CONCLUSIONS: Specific teaching behaviors may help or hinder learning of endoscopic skills. These behaviors may be useful for efforts related to teaching evaluation, faculty development, and direct teaching. PMID- 29574014 TI - Notch signaling and neuronal death in stroke. AB - Ischemic stroke is a leading cause of morbidity and death, with the outcome largely determined by the amount of hypoxia-related neuronal death in the affected brain regions. Cerebral ischemia and hypoxia activate the Notch1 signaling pathway and four prominent interacting pathways (NF-kappaB, p53, HIF 1alpha and Pin1) that converge on a conserved DNA-associated nuclear multi protein complex, which controls the expression of genes that can determine the fate of neurons. When neurons experience a moderate level of ischemic insult, the nuclear multi-protein complex up-regulates adaptive stress response genes encoding proteins that promote neuronal survival, but when ischemia is more severe the nuclear multi-protein complex induces genes encoding proteins that trigger and execute a neuronal death program. We propose that the nuclear multi protein transcriptional complex is a molecular mediator of neuronal hormesis and a target for therapeutic intervention in stroke. PMID- 29574018 TI - Does Orthopaedic Training Compromise the Outcome in Knee Joint Arthroplasty? AB - OBJECTIVE: This study investigates knee joint arthroplasty and compares the outcomes between attending (consultant) orthopedic surgeons and resident (trainee) surgeons. DESIGN: Retrospective review and comparison of knee joint arthroplasty outcomes between 4 surgeon groups (attending, supervised senior and junior residents, and unsupervised senior residents). Measured outcomes were implant survival (revision rate) and patient reported functional outcomes, measured by Oxford knee score (OKS). SETTING: New Zealand arthroplasty service. PARTICIPANTS: Seventeen years of knee joint arthroplasty data from the New Zealand Joint Registry (NZJR) was reviewed. RESULTS: The New Zealand Joint Registry (NZJR) data showed 79,671 total knee arthroplasties (TKA) and 8854 unicompartmental knee arthroplasties (UKA) performed between 1999 and 2016. Attending surgeons performed 90% and 97% of TKA and UKA, respectively. The number and proportion of resident performed knee joint arthroplasty has decreased. Faster operation times was observed in the attending surgeon group. Attending surgeon revision rate was 0.49 and 1.19/100 component years for TKA and UKA, respectively, this was not significantly increased in resident surgeon groups. Postoperative OKS was 37.7 and 39.7 for attending surgeon performed TKA and UKA, respectively. Mean OKS were less than 2 points worse in resident groups (resident range: 36.3-36.9) compared to attending colleagues for TKA, but for UKA scores were up to 11 points worse (resident range: 28.9-38.8). CONCLUSIONS: New Zealand has a high rate of attending surgeon performed TKA and UKA. Revision rates were not increased in resident surgeon groups. Postoperative function was not reduced by a clinically significant amount in TKA in any of the resident surgeon groups but was reduced in supervised junior resident and unsupervised senior resident surgeon groups for UKA.

AB - OBJECTIVE: To compare the effect of simulator functional fidelity (manikin vs a Dynamic Haptic Robotic Trainer [DHRT]) and personalized feedback on surgical resident self-efficacy and self-ratings of performance during ultrasound-guided internal jugular central venous catheterization (IJ CVC) training. In addition, we seek to explore how self-ratings of performance compare to objective performance scores generated by the DHRT system. DESIGN: Participants were randomly assigned to either manikin or DHRT IJ CVC training over a 6-month period. Self-efficacy surveys were distributed before and following training. Training consisted of a pretest, 22 practice IJ CVC needle insertion attempts, 2 full-line practice attempts, and a posttest. Participants provided self-ratings of performance for each needle insertion and were presented with feedback from either an upper level resident (manikin) or a personalized learning system (DHRT). SETTING: A study was conducted from July 2016 to February 2017 through a surgical skills training program at Hershey Medical Center in Hershey, Pennsylvania. PARTICIPANTS: Twenty-six first-year surgical residents were recruited for the study. Individuals were informed that IJ CVC training procedures would be consistent regardless of participation in the study and that participation was optional. All recruited residents opted to participate in the study. RESULTS: Residents in both groups significantly improved their self efficacy scores from pretest to posttest (p < 0.01). Residents in the manikin group consistently provided higher self-ratings of performance (p < 0.001). Residents in the DHRT group recorded more feedback on errors (228 instances) than the manikin group (144 instances). Self-ratings of performance on the DHRT system were able to significantly predict the objective score of the DHRT system (R2 = 0.223, p < 0.001). CONCLUSION: Simulation training with the DHRT system and the personalized learning feedback can improve resident self-efficacy with IJ CVC procedures and provide sufficient feedback to allow residents to accurately assess their own performance.

Furthermore, lung cancer is the leading cause of cancer deaths worldwide. It is an emergency to develop a powerful strategy to treat these threatening cancers more effectively, because of low efficacy and high rates of chemotherapy effects. MicroRNAs (miRNAs), a class of small non-coding RNAs, are key regulators of gene expression via induction of translational repression or mRNA degradation. MiRNA deregulation has been linked to cancer initiation and progression. Silent Inflammation Regulator 2 (SIR2) proteins sirtuins- are a family of histone deacetylases (HDACs) that catalyze deacetylation of both histone and non- histone lysine residues. SIRT1 can act as an oncogene. It plays a role in tumorigenesis by anti-apoptotic activity and is implicated in diverse cellular process including autophagy, senescence, apoptosis, proliferation, and aging. MicroRNAs and SIRT1 serve as tumor suppressors or tumor promotors depending on the oncogenic pathway specific to particular tumors. MicroRNAs modulate cancer development by targeting SIRT1. In this review, we underlie the specific mechanisms involved in these threatening cancers by microRNAs/SIRT1 pathways. PMID- 29574021 TI - HIF-dependent and reversible nucleosome disassembly in hypoxia-inducible gene promoters. AB - Hypoxia causes dramatic changes in gene expression profiles, and the mechanism of hypoxia-inducible transcription has been analyzed for use as a model system of stress-inducible gene regulation. In this study, changes in chromatin organization in promoters of hypoxia-inducible genes were investigated during hypoxia-reoxygenation conditions. Most of the hypoxia-inducible gene promoters were hypersensitive to DNase I under both normal and hypoxic conditions, and our data indicate an immediate recruitment of transcription factors under hypoxic conditions. In some of the hypoxia-inducible promoters, nucleosome-free DNA regions (NFRs) were established in parallel with hypoxia-induced transcription. We also show that the hypoxia-inducible formation of NFRs requires that hypoxia inducible transcription factors (HIFs) bind to the promoters together with the transcriptional coactivator CBP. Within 1 h after the hypoxia exposure was ended (reoxygenation), HIF complexes were dissociated from the promoter regions. Within 24 h of reoxygenation, the hypoxia-induced transcription returned to basal levels and the nucleosome structure was reassembled in the hypoxia-inducible NFRs. Nucleosome reassembly required the function of the transcriptional coregulator SIN3A. Thus, reversible changes in nucleosome organization mediated by transcription factors are notable features of stress-inducible gene regulation. PMID- 29574022 TI - Analysis of TCRbeta and TCRgamma genes in Chinese alligator provides insights into the evolution of TCR genes in jawed vertebrates. AB - All jawed vertebrates have four T cell receptor (TCR) chains that are expressed by thymus-derived lymphocytes and play a major role in animal immune defence. However, few studies have investigated the TCR chains of crocodilians compared with those of birds and mammals, despite their key evolutionary position linking amphibians, reptiles, birds and mammals. Here, employing an Alligator sinensis genomic bacterial artificial chromosome (BAC) library and available genome data, we characterized the genomic organization, evolution and expression of TRB and TRG loci in Alligator sinensis. According to the sequencing data, the Alligator sinensis TRB locus spans approximately 500 Kb of genomic DNA containing two D-J-C clusters and 43 V gene segments and is organized as Vbeta(39)-pJbeta1-pCbeta1 pDbeta1-Dbeta2- Jbeta2(12)-Cbeta2-Vbeta(4), whereas the TRG locus spans 115 Kb of DNA genomic sequence consisting of 18 V gene segments, nine J gene segments and one C gene segment and is organized in a classical translocon pattern as Vgamma(18)-Jgamma(9)-Cgamma. Moreover, syntenic analysis of TRB and TRG chain loci suggested a high degree of conserved synteny in the genomic regions across mammals, birds and Alligator sinensis. By analysing the cloned TRB/TRG cDNA, we identified the usage pattern of V families in the expressed TRB and TRG. An analysis of the junctions of the recombined VJ revealed the presence of N and P nucleotides in both expressed TRB and TRG sequences. Phylogenetic analysis revealed that TRB and TRG loci possess distinct evolutionary patterns. Most Alligator sinensis V subgroups have closely related orthologues in chicken and duck, and a small number of Alligator sinensis V subgroups have orthologues in mammals, which supports the hypothesis that crocodiles are the closest relatives of birds and mammals. Collectively, these data provide insights into TCR gene evolution in vertebrates and improve our understanding of the Alligator sinensis immune system. PMID- 29574023 TI - Progression of Treated versus Untreated Liver Imaging Reporting and Data System Category 4 Masses after Transcatheter Arterial Embolization Therapy. AB - PURPOSE: To compare outcomes of treated vs untreated Liver Imaging Reporting and Data System category 4 (LR-4) masses after transcatheter arterial embolization. MATERIALS AND METHODS: In 167 patients undergoing embolization for HCC from January 2005 to December 2012, LR-4 masses were retrospectively identified on CT and MR imaging examinations performed before embolization. In 149 patients undergoing embolization from January 2013 to December 2016, masses prospectively classified as LR-4 were identified. In total, there were 81 LR-4 masses in 62 patients (16 women; mean age 62 y; range 29-83 y). Procedures were reviewed to determine whether LR-4 masses were within or outside the liver volume that received embolization during treatment of dominant masses. Time to progression to LR-5 and by modified Response Evaluation Criteria in Solid Tumors (mRECIST) was estimated for treated vs untreated LR-4 masses using the Kaplan-Meier method and compared using the log rank test. RESULTS: LR-4 masses averaged 1.8 cm; 88%, 60%, 14%, and 14% demonstrated arterial phase hyperenhancement, washout, a capsule, and growth. Of LR-4 masses, 62 were within the liver volume that received embolization and considered treated, and 19 were outside and considered untreated. Response rates according to mRECIST were 37% vs 21% for treated vs untreated masses (P = .27). The 6- and 12-month rates of progression to LR-5 were 7% and 26% for treated masses vs 27% and 75% for untreated masses (P = .001). According to mRECIST, 7% and 27% of treated masses progressed vs 30% and 65% of untreated masses (P = .001). CONCLUSIONS: LR-4 masses that receive embolization in the setting of dominant masses elsewhere show lower rates of progression compared with untreated masses. PMID- 29574025 TI - Effects of Multi-Electrode Renal Denervation on Insulin Sensitivity and Glucose Metabolism in a Canine Model of Type 2 Diabetes Mellitus. AB - PURPOSE: To evaluate the effects of multi-electrode catheter-based renal denervation (RDN) on insulin sensitivity and glucose metabolism in a type 2 diabetes mellitus (T2DM) canine model. MATERIALS AND METHODS: Thirty-three dogs were divided equally into 3 groups: bilateral renal denervation (BRDN) group, left renal denervation (LRDN) group, and sham operation (SHAM) group. Body weight and blood biochemistry were measured at baseline, 20 weeks, and 32 weeks, and renal angiography and computerized tomographic (CT) angiography were determined before the procedure and 1 month, 2 months, and 3 months after the procedure. Western blot was used to identify the activities of gluconeogenic enzymes and insulin-signaling proteins. RESULTS: Fasting plasma glucose (9.64 +/- 1.57 mmol/L vs 5.12 +/- 1.08 mmol/L; P < .0001), fasting insulin (16.19 +/- 1.43 mIU/mL vs 5.07 +/- 1.13 mIU/mL; P < .0001), and homeostasis-model assessment of insulin resistance (HOMA-IR; 6.95 +/- 1.33 vs 1.15 +/- 0.33; P < .0001) in the BRDN group had significantly decreased at the 3-month follow-up compared with the SHAM group. Western blot analyses showed that RDN suppressed the gluconeogenetic genes, modulated insulin action, and activated insulin receptors-AKT signaling cascade in the liver. CT angiography and histopathologic analyses did not show any dissection, aneurysm, thrombus, or rupture in any of the renal arteries. CONCLUSIONS: These findings identified that multi-electrode catheter-based RDN could effectively decrease gluconeogenesis and glycogenolysis, resulting in improvements in insulin sensitivity and glucose metabolism in a T2DM canine model.

PMID- 29574026 TI - In vitro antioxidant activity of thiazolidinone derivatives of 1,3-thiazole and 1,3,4-thiadiazole. AB - The initial steps in preclinical drug developing research concern the synthesis of new compounds for specific therapeutic use which needs to be confirmed by in vitro and then in vivo testing. Nine thiazolidinone derivatives (numerically labeled 1-9) classified as follows: 1,3-thiazole-based compounds (1 and 2); 1,3,4 thiadiazole based compounds (3 and 4); substituted 5-benzylideno-2 adamantylthiazol[3,2-b][1,2,4]triazol-6(5H)ones (5-8); and an ethylaminothiazole based chalcone (9), were tested for antioxidant activity (AOA) by using three in vitro assays: DPPH (1,1-diphenyl-2-picrylhydrazyl scavenging capacity test); FRAP (ferric reducing antioxidant power test); and TBARS (thiobarbituric acid reactive substances test). Compounds 1-4 and 9 in particular are newly synthesized compounds. Also, traditional antioxidants Vitamins E and C and alpha-lipoic acid (alpha-LA) were tested. The results of DPPH testing: Vitamin C 94.35%, Vitamin E 2.99% and alpha-LA 1.57%; compounds: 4 33.98%; 2 18.73%; 1 15.62%; 5 6.59%; 3 4.99%; 6-9 demonstrated almost no AOA. The results of TBARS testing (% of LPO inhibition): Vitamin C 62.32%; Vitamin E 36.29%; alpha-LA 51.36%; compounds: 1 62.11%; 5 66.71%; 9 60.93%; 4, 6 and 7 demonstrated ~50%; 3 and 8 displayed ~38%; 2 23.51%. By FRAP method, Vitamins E and C showed equal AOA, ~100%, unlike alpha LA (no AOA), and AOA of the tested compounds (expressed as a fraction of the AOA of Vitamin C) were: 2 and 4-75%; 8, 3 and 1-45%; 5-7 and 9-27%. Different red-ox reaction principles between these assays dictate different AOA outcomes for a single compound. Vitamin C appeared to be the superior antioxidant out of the traditional antioxidants; and compound 4 was superior to other tested thiazolidinone derivatives. Vitamin C appeared to be the superior antioxidant out of the traditional antioxidants; and compound 4 was superior to other tested thiazolidinone derivatives. Phenyl-functionalized benzylidene, amino-carbonyl functional domains and chelating ligand properties of the thiazolidinone derivatives correlated with AOA.

AB - Lead (Pb) is one of the most prevalent toxic, nonessential heavy metals that has been associated with a wide range of toxic effects in humans and environmental animals. Here, effects of short time exposure to 10 and 30 MUg/L Pb on gut microbiota and hepatic metabolism were analyzed in adult male zebrafish. We observed that both 10 and 30 MUg/L Pb increased the volume of mucus in the gut. At phylum level, the abundance of alpha-Proteobacteria decreased significantly and the abundance of Firmicutes increased significantly in the gut when treated with 30 MUg/L Pb for 7 days. In addition, the 16S rRNA gene sequencing for V3-V4 region revealed a significant change in the richness and diversity of gut microbiota in 30 MUg/L Pb exposed group. A more depth analysis, at the genus level, discovered that 52 gut microbes identified by operational taxonomic unit analysis were changed significantly in 30 MUg/L Pb treated group. Based on GC/MS metabolomics analysis, a total of 41 metabolites were significantly altered in 30 MUg/L Pb treatment group. These changed metabolites were mainly associated with the pathways of glucose and lipid metabolism, amino acid metabolism, nucleotide metabolism. In addition, we also confirmed that the transcription of some genes related to glycolysis and lipid metabolism, including Gk, Aco, Acc1, Fas, Apo and Dgat, decreased significantly in the liver of zebrafish when exposed to 30 MUg/L Pb for 7 days. Our results observed that Pb could cause gut microbiota dysbiosis and hepatic metabolic disorder in zebrafish. PMID- 29574033 TI - Computational neuroanatomy of baby brains: A review. AB - The first postnatal years are an exceptionally dynamic and critical period of structural, functional and connectivity development of the human brain. The increasing availability of non-invasive infant brain MR images provides unprecedented opportunities for accurate and reliable charting of dynamic early brain developmental trajectories in understanding normative and aberrant growth. However, infant brain MR images typically exhibit reduced tissue contrast (especially around 6 months of age), large within-tissue intensity variations, and regionally-heterogeneous, dynamic changes, in comparison with adult brain MR images. Consequently, the existing computational tools developed typically for adult brains are not suitable for infant brain MR image processing. To address these challenges, many infant-tailored computational methods have been proposed for computational neuroanatomy of infant brains. In this review paper, we provide a comprehensive review of the state-of-the-art computational methods for infant brain MRI processing and analysis, which have advanced our understanding of early postnatal brain development. We also summarize publically available infant dedicated resources, including MRI datasets, computational tools, grand challenges, and brain atlases. Finally, we discuss the limitations in current research and suggest potential future research directions. PMID- 29574034 TI - Cerebrovascular reactivity (CVR) MRI with CO2 challenge: A technical review. AB - Cerebrovascular reactivity (CVR) is an indicator of cerebrovascular reserve and provides important information about vascular health in a range of brain conditions and diseases. Unlike steady-state vascular parameters, such as cerebral blood flow (CBF) and cerebral blood volume (CBV), CVR measures the ability of cerebral vessels to dilate or constrict in response to challenges or maneuvers. Therefore, CVR mapping requires a physiological challenge while monitoring the corresponding hemodynamic changes in the brain. The present review primarily focuses on methods that use CO2 inhalation as a physiological challenge while monitoring changes in hemodynamic MRI signals. CO2 inhalation has been increasingly used in CVR mapping in recent literature due to its potency in causing vasodilation, rapid onset and cessation of the effect, as well as advances in MRI-compatible gas delivery apparatus. In this review, we first discuss the physiological basis of CVR mapping using CO2 inhalation. We then review the methodological aspects of CVR mapping, including gas delivery apparatus, the timing paradigm of the breathing challenge, the MRI imaging sequence, and data analysis. In addition, we review alternative approaches for CVR mapping that do not require CO2 inhalation. PMID- 29574036 TI - Prognostic Scoring System for Patients Undergoing Reconstructive Foot and Ankle Surgery for Charcot Neuroarthropathy: The Charcot Reconstruction Preoperative Prognostic Score. AB - Charcot neuroarthropathy is a destructive process that occurs in patients with peripheral neuropathy, often due to poorly controlled diabetes mellitus. Surgical reconstruction can be necessary to provide a plantigrade foot that is wound free. A risk of major amputation exists after a Charcot event and after attempted reconstruction. We retrospectively reviewed the data from 34 patients (36 reconstructions) who had undergone reconstructive surgery for Charcot neuroarthropathy. The mean patient age was 56.44 years. The mean follow-up period was 56 months. We collected patient age, body mass index, presence of wound or osteomyelitis, anatomic location, activity of disease, and hemoglobin A1c. Using these data, each patient was given a score using our novel prognostic scoring system, the Charcot Reconstruction Preoperative Prognostic Score (CRPPS). Our primary outcome measure was no wound and no major amputation at the final follow up visit. The limb salvage rate was 89% (32 of 36), and 78% (28 of 36) had no wound at the final follow-up examination. For patients without a wound or major amputation at the final follow-up visit, the mean CRPPS was 2.96 +/- 1.23. The mean CRPPS for those with a wound or major amputation at the final follow-up visit was 4.33 +/- 1.07 (p = .0024). Univariate logistic regression revealed 2 statistically significant predictors of wound and/or amputation: anatomic location (odds ratio [OR] 5.0, 95% confidence interval [CI] 1.051 to 23.789; p = .043) and CRPPS (OR 2.724, 95% CI 1.274 to 5.823, p = .01). A CRPPS of >=4 was also predictive of a negative outcome (OR 7.286, 95% CI 1.508 to 35.211; p = .013). This scoring system, with a sensitivity of 75%, specificity of 71%, and negative predictive value of 85%, is a potential starting point when educating patients and making treatment decisions in this exceptionally challenging group. PMID- 29574037 TI - Microsurgical Replantation of the Posterior Heel Skin and Subcutaneous Tissue. AB - A 45-year-old male presented with amputation of posterior heel soft tissue after an accident involving broken glass panes. The defect measured 4 * 6.5 cm, and the composite amputated tissue consisted of skin and subcutaneous layers. Intraoperative exploration of the amputated tissue revealed 2 perforator arteries (diameter <=0.4 mm) in the central portion of the subcutaneous tissue and 4 superficial veins (diameter ~0.6 mm) in the wound margin. These vessels were anastomosed end-to-end to the corresponding vessels from the wound bed using 11-0 nylon sutures. The replanted tissue survived completely. The patient retained excellent aesthetic and functional outcomes at the 13-month follow-up visit. The present case serves to demonstrate the feasibility of microsurgical replantation for the posterior heel. Although such isolated amputations are far less common than digital amputations, our experience suggests that microsurgical replantation is indicated beyond the current spectrum of clinical repertoire.

AB - Autoimmune diseases are immune system disorders in which immune cells cannot distinguish self-antigens from foreign ones. The current criteria for autoimmune disease diagnosis are based on clinical manifestations and laboratory tests. However, none of these markers shows both high sensitivity and specificity. In addition, some autoimmune diseases, for example, systemic lupus erythematosus (SLE), are highly heterogeneous and often exhibit various manifestations. On the other hand, certain autoimmune diseases, such as Sjogren's syndrome versus SLE, share similar symptoms and autoantibodies, which also causes difficulties in diagnosis. Therefore, biomarkers that have both high sensitivity and high specificity for diagnosis, reflect disease activity and predict drug response are necessary. An increasing number of publications have proposed the abnormal epigenetic modifications as biomarkers of autoimmune diseases. Therefore, this review will comprehensively summarize the epigenetic progress in the pathogenesis of autoimmune disorders and unearth potential biomarkers that might be appropriate for disease diagnosis and prediction. PMID- 29574039 TI - Phase Ib trial of folate binding protein (FBP)-derived peptide vaccines, E39 and an attenuated version, E39': An analysis of safety and immune response. AB - : In this randomized phase Ib trial, we tested combining the E39 peptide vaccine with a vaccine created from E39', an attenuated version of E39. Patients with breast or ovarian cancer, who were disease-free after standard of care therapy, were enrolled and randomized to one of three arms. Arm EE received six E39 inoculations; arm EE' received three E39 inoculations followed by three E39'; and arm E'E received three E39' inoculations, followed by three E39. Within each arm, the first five patients received 500 MUg of peptide and the remainder received 1000 MUg. Patients were followed for toxicity, and immune responses were measured. This initial analysis after completion of the primary vaccination series has confirmed the safety of both vaccines. Immune analyses suggest incorporating the attenuated version of the peptide improves immune responses and that sequencing of E39 followed by E39' might produce the optimal immune response. TRIAL REGISTRATION: NCT02019524. PMID- 29574041 TI - In vivo evaluation of an oral self-emulsifying drug delivery system (SEDDS) for exenatide. AB - BACKGROUND: The aim of the study was to develop an oral self-emulsifying drug delivery system (SEDDS) for exenatide and to evaluate its in vivo efficacy. METHODS: Exenatide was lipidised via hydrophobic ion pairing with sodium docusate (DOC) and incorporated in SEDDS consisting of 35% Cremophor EL, 25% Labrafil 1944, 30% Capmul-PG 8 and 10% propylene glycol. Exenatide/DOC was characterized in terms of lipophilicity evaluating the octanol/water phase distribution (logP). Exenatide/DOC SEDDS were characterized via droplet size analysis, drug release characteristics (log DSEDDS/release medium determination) and mucus permeation studies. Furthermore, the impact of orally administered exenatide/DOC SEDDS on blood glucose level was investigated in vivo on healthy male Sprague-Dawley rats. RESULTS: Hydrophobic ion pairing in a molar ratio of 1:4 (exenatide:DOC) increased the effective logP of exenatide from -1.1 to 2.1. SEDDS with a payload of 1% exenatide/DOC had a mean droplet size of 45.87 +/- 2.9 nm and a Log DSEDDS/release medium of 1.9 +/- 0.05. Permeation experiments revealed 2.7-fold improved mucus diffusion for exenatide/DOC SEDDS compared to exenatide in solution. Orally administered exenatide/DOC SEDDS showed a relative bioavailability (versus s.c.) of 14.62% +/- 3.07% and caused a significant (p < .05) 20.6% decrease in AUC values of blood glucose levels. CONCLUSION: According to these results, hydrophobic ion pairing in combination with SEDDS represents a promising tool for oral peptide delivery.

AB - Development of carrier-based dry powder inhalation formulations follows till date empirical approaches. This is mainly underlain by numerousness of interplaying determinants of performance and complexity of involved interactions. Mathematical modeling helps elucidate such interactions and aids rational development of formulations. This article provides a critical overview of attempts made to model the performance of carrier-based dry powder inhalation formulations. The complex dependence of the performance on formulation properties is comprehensively discussed. A potential microstructure-based model is ultimately introduced. PMID- 29574043 TI - Eating patterns of US adults: Meals, snacks, and time of eating. AB - The objective of this paper is to update knowledge of eating patterns of US adults with sex and ethnicity specific estimates and discuss the implications of reported patterns with respect to current resurgence of interest in the topic. The eating patterns data were from the NHANES 2009-2014 (n = 15,341 adults). Overall, American adults reported 4.96 +/- 0.03 eating episodes in the recall. Women were more likely to report each of the three main meals and all three meals plus one or more snacks relative to men (P < 0.0001). Relative to other ethnic groups, non-Hispanic blacks were less likely to report each meal or a snack or all three meals, and the foods reported for meals and snacks were higher in energy density (P = 0.0001). Of the three meals, the dinner meal, and among snacks, the after-dinner snack, were reported by the highest percentage of Americans; these two eating episodes provided nearly 45% of the 24-h energy intake. The average dinnertime was 6:24 pm, and the average time of the last eating episode of the 24-h ingestive period was 8:18 pm. Given these findings, adoption of eating patterns that advocate less frequent eating and shift in the time of eating are likely to present a challenge. We know little about the validity of eating patterns determined from 24-h recalls or questionnaire instruments. The extent of within person variability and reporting errors in different eating pattern components also need further research. PMID- 29574044 TI - Ultrasonic vocalization in juvenile and adult male rats: A comparison among stocks. AB - Ultrasonic vocalizations (USV) are widely studied in mice and rats, and in case of rats, the bulk of empirical evidence is based on outbred rats, which in most studies belong to either Long Evans, Sprague-Dawley or Wistar stocks. It is known that these stocks can differ in terms of specific brain variables and also behaviorally, but there is only few evidence so far showing whether these stocks behave in similar or substantially different ways in paradigms which are often used to study USV. Therefore, we have started a larger series of comparative studies, where we analyzed different classes of USV in rats from these three stocks spanning from pups to adults. Here, we report our findings in juvenile and adult male Long Evans, Sprague-Dawley and Wistar rats, which we tested as juveniles for appetitive 50-kHz calls during a so-called cage test or when being tickled by an experimenter, and later as adults for 22-kHz calls in a fear conditioning paradigm. In general, all three stocks showed the expected USV responses, indicating that they are all feasible for this kind of research. In detail, however, there were various quantitative differences between stocks both, in terms of specific USV features (like call rates, call durations etc.) as well as visible behavior, like spontaneous locomotor activity and shock-induced immobility. These findings are discussed in the context of the relevant, but somewhat equivocal literature on these stocks, including factors which might contribute to such variability, like breeding, housing, or details of the given test. PMID- 29574045 TI - SOX2 expression diminishes with ageing in several tissues in mice and humans. AB - SOX2 (Sex-determining region Y box 2) is a transcription factor expressed in several foetal and adult tissues and its deregulated activity has been linked to chronic diseases associated with ageing. Nevertheless, the level of SOX2 expression in aged individuals at the tissue level has not previously been examined. In this work, we show that SOX2 expression decreases significantly in the brain with ageing, in both humans and rodents. The administration of resveratrol for 6 months in mice partly attenuated this reduction. We also identified an age-related decline in SOX2 mRNA and protein expression in several other organs, namely, the lung, heart, kidney, spleen and liver. Moreover, peripheral blood mononuclear cells (PBMCs) from elderly expressed lower levels of SOX2 than those from young individuals. Mechanistically, SOX2 expression inversely correlates with p16Ink4a levels. Together, these data show a widespread decrease in SOX2 with age, suggesting that the decline in SOX2 expression might be used as a biomarker of ageing.

AB - Like any discipline, psychoanalysis has evolved considerably since its inception by Freud over a century ago, and a multitude of different psychoanalytic traditions and schools of theory and practice now exist. However, some of Freud's original ideas, such as the dynamic unconscious, a developmental approach, defence mechanisms, and transference and countertransference remain essential tenets of psychoanalytic thinking to this day. This Review outlines several areas within modern mental health practice in which contemporary adaptations and applications of these psychoanalytic concepts might offer helpful insights and improvements in patient care and management, and concludes with an overview of evidence-based psychoanalytically informed treatments and the links between psychoanalysis, attachment research, and neuroscience.

AB - : The objective of this prospective long-term follow-up study was to investigate whether somatosensory function is altered among young adults born preterm with very low birth weight (VLBW; <=1,500 g) or small for gestational age (SGA; <10th percentile) at term. In a blinded quantitative sensory testing protocol, we determined thermal detection, thermal pain, and pressure pain thresholds and the response to prolonged supra-threshold heat among 51 VLBW, 66 term SGA, and 86 term-born controls (birth weight >=10th percentile) at 28 years. Self-reported chronic pain was also investigated. Except for increased sensitivity to cool in the term SGA group versus controls, we found no significant group differences regarding thermal or pain thresholds. Overall, male participants had higher pain thresholds, and no significant interactions of group and sex were observed (P > .14). Within the VLBW group, neonatal mechanical ventilation was associated with reduced sensitivity to cool, and length of mechanical ventilation correlated with lower pressure pain thresholds. The response to prolonged supra-threshold heat was similar between the groups, and the prevalence of self-reported chronic pain was not reliably different. In conclusion, low birth weight young adults were as sensitive to thermal and pain stimuli as term-born, normal birth weight controls, with the same sex differences. PERSPECTIVE: To our knowledge, this is the first report on thermal and pain sensitivity among young adults born preterm with VLBW or SGA at term. The negative results from a comprehensive quantitative sensory testing protocol oppose previous findings of altered sensory perception among children and adolescents born preterm.

AB - The distribution of allele frequencies obtained from diffusion approximations to Wright-Fisher models is useful in developing intuition about the population level effects of evolutionary processes. The statistical properties of the stationary distributions of K-allele models have been extensively studied under neutrality or under selection. Here, we introduce a new family of Wright-Fisher models in which there are two hierarchical levels of genetic variability. The genotypes composed of alleles differing from each other at the selected level have fitness differences with respect to each other and evolve under selection. The genotypes composed of alleles differing from each other only at the neutral level have the same fitness and evolve under neutrality. We show that with an appropriate scaling of the mutation parameter with respect to the number of alleles at each level, the frequencies of alleles at the selected and the neutral level are conditionally independent of each other, conditional on knowing the number of alleles at all levels. This conditional independence allows us to simulate from the joint stationary distribution of the allele frequencies. We use these simulated frequencies to perform inference on parameters of the model with two levels of genetic variability using Approximate Bayesian Computation.

AB - Dimethylsulfoniopropionate (DMSP) is one of the most abundant molecules on earth and plays a pivotal role in the marine sulfur cycle. DMSP is believed to be synthesized from methionine by a four-step reaction pathway in marine algae. The genes responsible for biosynthesis of DMSP remain unidentified. A diatom Thalassiosira pseudonana CCMP1335 is an important component of marine ecosystems and contributes greatly to the world's primary production. In this study, through genome search, in vivo activity and functional studies of cDNA products, a gene encoding Thalassiosira methyltransferase (TpMMT) which catalyzes the key step of DMSP synthesis formation of 4-methylthio-2-hydroxybutyrate (DMSHB) from 4 methylthio-2-oxobutyrate (MTHB), was identified. The amino acid sequence of TpMMT was homologous to the methyltransferase from Phaeodactylum tricornutum CCAP 1055/1, but not the recently identified bacterium gene. High salinity and nitrogen limitation stresses caused the increase of DMSP content and TpMMT protein in Thalassiosira. In addition to TpMMT, the enzyme activities for the first three steps could be detected and enhanced under high salinity, suggesting the importance of four-step DMSP synthetic pathway in Thalassiosira.

AB - Quercetin is a major flavonoid, present as its glycosidic forms in plant foods. In this study, quercetin-3-glucoside (Q3G) was administered intraduodenally to thoracic lymph-cannulated rats, and its lymphatic transport was investigated. The resulting lymphatic and plasma metabolites were identified with LC-MS/MS and compared with those after administration of quercetin aglycone. The total concentration of quercetin metabolites in the lymph was about four times lower than that in the plasma, and quercetin and its methylated form isorhamnetin were detected as their glucuronides, sulfates and diglucuronides both in the lymph and the plasma after Q3G and quercetin administrations. The lymph levels of the glucuronides after Q3G administration were lower than those after quercetin administration, whereas those in the plasma showed the opposite pattern. Both the lymph and plasma levels of the sulfates after Q3G administration were lower than those after quercetin administration. Some of the intestinal metabolites like quercetin monoglucuronides were transported directly into the lymph and the hepatic metabolites like the diglucuronides were eventually transferred from the plasma into the lymph. These results indicate that the absorbed Q3G is partly transported into the intestinal lymph as quercetin metabolites. Deglycosylation in the enterocyte is also suggested to affect the subsequent metabolic pathways.

AB - This article reports a case of cervico-isthmic disjunction unnoticed during childhood, diagnosed in a context of primary infertility and endometriosis, and surgically treated. It is an uncommon condition. The diagnosis is most often made as part of an assessment of primary amenorrhea in a young woman with a history of severe pelvic trauma. It is suspected after imaging assessment and confirmed intraoperatively. The treatment consists in an anastomosis between the cervix and the uterine body, after individualizing these two structures, around a drain guiding healing. After this surgery, multiple pregnancies have been successfully carried out. PMID- 29574054 TI - Uterine transplantation: Review in human research. AB - Uterine transplantation is the solution to treat absolute uterine fertility.

We reviewed the PubMed database following PRISMA guidelines and added data presented by several research teams during the first international congress on uterine transplantation. PMID- 29574055 TI - Tuning Transcriptional Regulation through Signaling: A Predictive Theory of Allosteric Induction. AB - Allosteric regulation is found across all domains of life, yet we still lack simple, predictive theories that directly link the experimentally tunable parameters of a system to its input-output response. To that end, we present a general theory of allosteric transcriptional regulation using the Monod-Wyman Changeux model. We rigorously test this model using the ubiquitous simple repression motif in bacteria by first predicting the behavior of strains that span a large range of repressor copy numbers and DNA binding strengths and then constructing and measuring their response. Our model not only accurately captures the induction profiles of these strains, but also enables us to derive analytic expressions for key properties such as the dynamic range and [EC50]. Finally, we derive an expression for the free energy of allosteric repressors that enables us to collapse our experimental data onto a single master curve that captures the diverse phenomenology of the induction profiles. PMID- 29574057 TI - A nomogram for classification of temporomandibular joint disk perforation based on magnetic resonance imaging. AB - OBJECTIVE: The aim of this study was to analyze risk factors and establish a prediction model for temporomandibular joint (TMJ) disk perforation by constructing a nomogram. STUDY DESIGN: The study included a total of 282 joints in 274 patients. All patients underwent open TMJ surgery after obtaining magnetic resonance imaging (MRI), from 2005 to 2015. The presence or absence of disk perforation was confirmed during the operation. Patients were classified into 2 groups: perforation and nonperforation groups. We investigated demographic data and the characteristics of the disk, joint space, and bone on MRI. A logistic regression analysis was performed to analyze risk factors. A nomogram was constructed and validated internally and externally. RESULTS: Risk factors for disk perforation were increased age, disk shape (eyeglass or amorphous), low bone marrow signal, abnormal joint space, and 2 or more bony changes in the condyle and fossa. The area under the receiver operating characteristic curve of the nomogram was 0.908 (95% confidence interval [CI] 0.869-0.946) in the internal validation and 0.889 (95% CI 0.804-0.973) in the external validation with good suitability. CONCLUSIONS: We were able to predict the probability of disk perforation with analyzed risk factors and constructed a nomogram, which may be helpful in proper diagnosis and treatment.

AB - Although the structure of a genetically encoded regulatory circuit is an important determinant of its function, the relationship between circuit topology and the dynamical behaviors it can exhibit is not well understood. Here, we explore the range of behaviors available to the AC-DC circuit. This circuit consists of three genes connected as a combination of a toggle switch and a repressilator. Using dynamical systems theory, we show that the AC-DC circuit exhibits both oscillations and bistability within the same region of parameter space; this generates emergent behaviors not available to either the toggle switch or the repressilator alone. The AC-DC circuit can switch on oscillations via two distinct mechanisms, one of which induces coherence into ensembles of oscillators. In addition, we show that in the presence of noise, the AC-DC circuit can behave as an excitable system capable of spatial signal propagation or coherence resonance. Together, these results demonstrate how combinations of simple motifs can exhibit multiple complex behaviors. PMID- 29574058 TI - Replacing zoledronic acid with denosumab is a risk factor for developing osteonecrosis of the jaw. AB - OBJECTIVE: Intravenous zoledronic acid (ZA) is often replaced with subcutaneous denosumab in patients with bone metastatic cancer. Despite their different pharmacologic mechanisms of action, both denosumab and ZA are effective in bone metastasis but cause osteonecrosis of the jaw (ONJ) as a side effect. ZA persists in the body almost indefinitely, whereas denosumab does not persist for long periods. This study evaluated the risks of developing ONJ when replacing ZA with denosumab. STUDY DESIGN: In total, 161 Japanese patients administered ZA for bone metastatic cancer were enrolled in this single-center, retrospective, observational study. The risk of developing ONJ was evaluated by logistic regression analysis using the following factors: age, gender, cancer type, angiogenesis inhibitors, steroids, and replacement of ZA with denosumab. RESULTS: Seventeen patients (10.6%) developed ONJ. Multiple regression analysis indicated a significant difference in rate of ONJ associated with replacement of ZA with denosumab (odds ratio = 3.81; 95% confidence interval 1.04-13.97; P = .043). CONCLUSIONS: Replacing ZA with denosumab is a risk factor for the development of ONJ. Both binding of bisphosphonate to bone and receptor activator of nuclear factor-kappa B ligand inhibition could additively increase the risk of ONJ. We bring the replacement of ZA with denosumab to the attention of clinical oncologists.

PMID- 29574060 TI - Radiculomegaly: a case report of this rare dental finding with review of the associated oculo-facio-cardio-dental syndrome. AB - BACKGROUND: Radiculomegaly, or root gigantism, is a rare dental abnormality with important clinical implications. It is highly specific for oculo-facio-cardio dental (OFCD) syndrome, which places dentists at the forefront of diagnosis of this syndrome. Only 1 case of nonsyndromic radiculomegaly has been reported in the literature since the description of OFCD syndrome in 1996. We present the second confirmed, nonsyndromic/nonfamilial case and review the literature for dental treatments in patients with this dental finding. STUDY DESIGN: A review of the English language literature was performed in PubMed for patients with radiculomegaly or OFCD syndrome. Teeth affected by radiculomegaly, gender, orodental findings, presence of OFCD syndrome, and dental treatment methods were recorded. RESULTS: Sixty-seven cases of radiculomegaly and 92 cases of OFCD syndrome were found in the literature. Only 1 confirmed case of nonsyndromic/nonfamilial radiculomegaly had been reported previously. Ten reports described dental treatment or treatment plan details, and even fewer included specific methods. CONCLUSIONS: Because dental anomalies, especially radiculomegaly, are a primary feature of OFCD syndrome, dentists should be aware of the clinical and radiographic features. Radiculomegaly poses a distinct challenge to dentists, and reports of dental therapy provided to these patients are sparse. Early diagnosis of the syndrome may prevent dental challenges and improve prognosis. PMID- 29574061 TI - Identification and characterization of two novel superantigens among Staphylococcus aureus complex. AB - Staphylococcal enterotoxins (SEs), also known as superantigens, play a very important role in infections and food poisoning caused by Staphylococcus aureus. Recently, S. argenteus and S. schweitzeri were recognized as novel species closely related to S. aureus. In this study of these three species, it was found that two putative SE genes were located upstream of some vSabeta pathogenicity islands and the deduced amino acid sequences showed < 65.3% identity with those of known SEs. The related proteins, designated staphylococcal enterotoxin-like toxin 26 (SEl26) and 27 (SEl27), were identified and characterized among the three species. The mRNAs encoding SEl26 and SEl27 were expressed during all the growth phases. Recombinant SEl26 and SEl27 exhibited superantigenic activity in human peripheral blood mononuclear cells and mouse splenocytes by examining cell proliferation and cytokine production. Interestingly, these two genes were present universally in S. argenteus sequence type 2250 with clinical importance. Meanwhile, SEl27 variants from different species showed differential sensitivity to human peripheral blood mononuclear cells, which corresponded to the primary bacterial species hosts. It was demonstrated from these results that SEl26 and SEl27 were characterized to be two novel SE toxins and some SEs evolved along with the bacteria when the organisms adapted the hosts' immune systems.

AB - Hyaluronan, a major extracellular matrix component, is an active participant in many disease states, including inflammatory bowel disease (IBD). The synthesis of this dynamic polymer is increased at sites of inflammation. Hyaluronan together with the enzymes responsible for its synthesis, degradation, and its binding proteins, directly modulates the promotion and resolution of disease by controlling recruitment of immune cells, by release of inflammatory cytokines, and by balancing hemostasis. This review discusses the functional significance of hyaluronan in the cells and tissues involved in inflammatory bowel disease pathobiology.

PMID- 29574066 TI - Impaired Ca2+ handling in resistance arteries from genetically obese Zucker rats: Role of the PI3K, ERK1/2 and PKC signaling pathways. AB - The impact of obesity on vascular smooth muscle (VSM) Ca2+ handling and vasoconstriction, and its regulation by the phosphatidylinositol 3-kinase (PI3K), mitogen activated protein kinase (MAPK) and protein kinase C (PKC) were assessed in mesenteric arteries (MA) from obese Zucker rats (OZR). Simultaneous measurements of intracellular Ca2+ ([Ca2+]i) and tension were performed in MA from OZR and compared to lean Zucker rats (LZR), and the effects of selective inhibitors of PI3K, ERK-MAPK kinase and PKC were assessed on the functional responses of VSM voltage-dependent L-type Ca2+ channels (CaV1.2). Increases in [Ca2+]i induced by alpha1-adrenoceptor activation and high K+ depolarization were not different in arteries from LZR and OZR although vasoconstriction was enhanced in OZR. Blockade of the ryanodine receptor (RyR) and of Ca2+ release from the sarcoplasmic reticulum (SR) markedly reduced depolarization-induced Ca2+ responses in arteries from lean but not obese rats, suggesting impaired Ca2+ induced Ca2+ release (CICR) from SR in arteries from OZR. Enhanced Ca2+ influx after treatment with ryanodine was abolished by nifedipine and coupled to up regulation of CaV1.2 channels in arteries from OZR. Increased activation of ERK MAPK and up-regulation of PI3Kdelta, PKCbeta and delta isoforms were associated to larger inhibitory effects of PI3K, MAPK and PKC blockers on VSM L-type channel Ca2+ entry in OZR. Changes in arterial Ca2+ handling in obesity involve SR Ca2+ store dysfunction and enhanced VSM Ca2+ entry through L-type channels, linked to a compensatory up-regulation of CaV1.2 proteins and increased activity of the ERK MAPK, PI3Kdelta and PKCbeta and delta, signaling pathways. PMID- 29574067 TI - Structure-kinetic relationship studies of cannabinoid CB2 receptor agonists reveal substituent-specific lipophilic effects on residence time. AB - A decade ago, the drug-target residence time model has been (re-)introduced, which describes the importance of binding kinetics of ligands on their protein targets. Since then, it has been applied successfully for multiple protein targets, including GPCRs, for the development of lead compounds with slow dissociation kinetics (i.e. long target residence time) to increase in vivo efficacy or with short residence time to prevent on-target associated side effects. To date, this model has not been applied in the design and pharmacological evaluation of novel selective ligands for the cannabinoid CB2 receptor (CB2R), a GPCR with therapeutic potential in the treatment of tissue injury and inflammatory diseases. Here, we have investigated the relationships between physicochemical properties, binding kinetics and functional activity in two different signal transduction pathways, G protein activation and beta arrestin recruitment. We synthesized 24 analogues of 3-cyclopropyl-1-(4-(6-((1,1 dioxidothiomorpholino)methyl)-5-fluoropyridin-2-yl)benzyl)imidazoleidine-2,4 dione (LEI101), our previously reported in vivo active and CB2R-selective agonist, with varying basicity and lipophilicity. We identified a positive correlation between target residence time and functional potency due to an increase in lipophilicity on the alkyl substituents, which was not the case for the amine substituents. Basicity of the agonists did not show a relationship with affinity, residence time or functional activity. Our findings provide important insights about the effects of physicochemical properties of the specific substituents of this scaffold on the binding kinetics of agonists and their CB2R pharmacology. This work therefore shows how CB2R agonists can be designed to have optimal kinetic profiles, which could aid the lead optimization process in drug discovery for the study or treatment of inflammatory diseases. PMID- 29574065 TI - Genetic sequencing for surveillance of drug resistance in tuberculosis in highly endemic countries: a multi-country population-based surveillance study. AB - BACKGROUND: In many countries, regular monitoring of the emergence of resistance to anti-tuberculosis drugs is hampered by the limitations of phenotypic testing for drug susceptibility. We therefore evaluated the use of genetic sequencing for surveillance of drug resistance in tuberculosis. METHODS: Population-level surveys were done in hospitals and clinics in seven countries (Azerbaijan, Bangladesh, Belarus, Pakistan, Philippines, South Africa, and Ukraine) to evaluate the use of genetic sequencing to estimate the resistance of Mycobacterium tuberculosis isolates to rifampicin, isoniazid, ofloxacin, moxifloxacin, pyrazinamide, kanamycin, amikacin, and capreomycin. For each drug, we assessed the accuracy of genetic sequencing by a comparison of the adjusted prevalence of resistance, measured by genetic sequencing, with the true prevalence of resistance, determined by phenotypic testing. FINDINGS: Isolates were taken from 7094 patients with tuberculosis who were enrolled in the study between November, 2009, and May, 2014. In all tuberculosis cases, the overall pooled sensitivity values for predicting resistance by genetic sequencing were 91% (95% CI 87-94) for rpoB (rifampicin resistance), 86% (74-93) for katG, inhA, and fabG promoter combined (isoniazid resistance), 54% (39-68) for pncA (pyrazinamide resistance), 85% (77-91) for gyrA and gyrB combined (ofloxacin resistance), and 88% (81-92) for gyrA and gyrB combined (moxifloxacin resistance). For nearly all drugs and in most settings, there was a large overlap in the estimated prevalence of drug resistance by genetic sequencing and the estimated prevalence by phenotypic testing. INTERPRETATION: Genetic sequencing can be a valuable tool for surveillance of drug resistance, providing new opportunities to monitor drug resistance in tuberculosis in resource-poor countries. Before its widespread adoption for surveillance purposes, there is a need to standardise DNA extraction methods, recording and reporting nomenclature, and data interpretation.

PMID- 29574068 TI - Natural product toosendanin reverses the resistance of human breast cancer cells to adriamycin as a novel PI3K inhibitor. AB - Adriamycin (ADM) is a commonly used drug in clinical breast cancer treatment. However, some breast cancer types or breast cancers subjected to repeated ADM exposure develop strong resistance to ADM thus limiting its clinical efficacy. In this study, we found for the first time that toosendanin (TSN), a triterpenoid extracted from the traditional Chinese medicine Melia toosendan Sieb et Zucc, could successfully reverse adriamycin resistance in human breast cancer cells. Immunofluorescence and HPLC analysis demonstrated that TSN promoted adriamycin accumulation in breast cancer cells, especially in the nucleus. Furthermore, TSN could significantly reduce ABCB1 expression. We then found that TSN was capable of suppressing adriamycin-induced Akt phosphorylation, probably due to downregulation of the PI3K catalytic subunits P110alpha and P110beta, and inhibition of DNA-PKcs. Importantly, the inhibitory effect of TSN on PI3K P110alpha and P110beta expression was specifically observed in breast cancer cells but not in normal human cells. Moreover, TSN significantly potentiated the anti-cancer effect of ADM in the 4T1 breast cancer model and its inhibition rate was nearly 90%. Thus, TSN could be used as a novel PI3K inhibitor to reverse breast cancer resistance. The combination of ADM and TSN may represent a useful strategy for human breast cancer therapy. PMID- 29574069 TI - Forskolin improves sensitivity to doxorubicin of triple negative breast cancer cells via Protein Kinase A-mediated ERK1/2 inhibition. AB - Triple negative breast cancer (TNBC) is an invasive, metastatic, highly aggressive tumor. Cytotoxic chemotherapy represents the current treatment for TNBC. However, relapse and chemo-resistance are very frequent. Therefore, new therapeutic approaches that are able to increase the sensitivity to cytotoxic drugs are needed. Forskolin, a natural cAMP elevating agent, has been used for several centuries in medicine and its safeness has also been demonstrated in modern studies. Recently, forskolin is emerging as a possible novel molecule for cancer therapy. Here, we investigate the effects of forskolin on the sensitivity of MDA-MB-231 and MDA-MB-468 TNBC cells to doxorubicin through MTT assay, flow cytometry-based assays (cell-cycle progression and cell death), cell number counting and immunoblotting experiments. We demonstrate that forskolin strongly enhances doxorubicin-induced antiproliferative effects by cell death induction. Similar effects are observed with IBMX and isoproterenol cAMP elevating agents and 8-Br-cAMP analog, but not by using 8-pCPT-2'-O-Me-cAMP Epac activator. It is important to note that the forskolin-induced potentiation of sensitivity to doxorubicin is accompanied by a strong inhibition of ERK1/2 phosphorylation, is mimicked by ERK inhibitor PD98059 and is prevented by pre-treatment with Protein Kinase A (PKA) and adenylate cyclase inhibitors. Altogether, our data indicate that forskolin sensitizes TNBC cells to doxorubicin via a mechanism depending on the cAMP/PKA-mediated ERK inhibition. Our findings sustain the evidence of anticancer activity mediated by forskolin and encourage the design of future in vivo/clinical studies in order to explore forskolin as a doxorubicin sensitizer for possible use in TNBC patients. PMID- 29574070 TI - Duality of statin action on lipoprotein subpopulations in the mixed dyslipidemia of metabolic syndrome: Quantity vs quality over time and implication of CETP. AB - BACKGROUND: Statins impact the metabolism, concentrations, composition, and function of circulating lipoproteins. OBJECTIVE: We evaluated time course relationships between statin-mediated reduction in atherogenic apolipoprotein B (ApoB)-containing particles and dynamic intravascular remodeling of ApoAI containing lipoprotein subpopulations in the mixed dyslipidemia of metabolic syndrome. METHODS: Insulin-resistant, hypertriglyceridemic, hypercholesterolemic, obese males (n = 12) were treated with pitavastatin (4 mg/d) and response evaluated at 6, 42, and 180 days. RESULTS: Reduction in low-density lipoprotein (LDL) cholesterol, ApoB, and triglycerides (TGs) was essentially complete at 42 days (-38%, -32%, and -35%, respectively); rapid reduction equally occurred in remnant cholesterol, ApoCII, CIII, and E levels (day 6; -35%, -50%, -23%, and 26%, respectively). Small dense LDLs (LDL4 and LDL5 subpopulations) predominated at baseline and were markedly reduced on treatment (-29% vs total LDL mass). Cholesteryl ester (CE) transfer protein activity and mass decreased progressively (-18% and -16%, respectively); concomitantly, TG depletion (up to -49%) and CE enrichment occurred in all high-density lipoprotein (HDL) particle subpopulations with normalization of CE/TG mass ratio at 180 days. ApoAI was redistributed from LpAI to LpAI:AII particles in HDL2a and HDL3a subpopulations; ApoCIII was preferentially depleted from LpAI:AII-rich particles on treatment. CONCLUSION: Overall, statin action exhibits duality in mixed dyslipidemia, as CE transfer protein-mediated normalization of the HDL CE/TG core lags markedly behind subacute reduction in elevated levels of atherogenic ApoB-containing lipoproteins. Normalization of the HDL neutral lipid core is consistent with enhanced atheroprotective function. The HDL CE/TG ratio constitutes a metabolomic marker of perturbed HDL metabolism in insulin-resistant states, equally allowing monitoring of statin impact on HDL metabolism, structure, and function. PMID- 29574071 TI - Poor attainment of lipid targets in patients with symptomatic peripheral artery disease. AB - BACKGROUND: Patients with peripheral artery disease (PAD) are at very high risk of future cardiovascular (CV) events. Strict lipid-lowering therapy is recommended. However, data on target level attainment are scarce. OBJECTIVE: The objective of the study was to investigate guideline equitable lipid lowering in a large observational study of symptomatic PAD patients. METHODS: Single-center observational study including 1109 patients with symptomatic PAD planned for revascularization at a tertiary university center. Between 2010 and 2017, guideline target level attainment trends over time and the association of statin therapy with CV mortality were analyzed. RESULTS: Atorvastatin (52.3%) and rosuvastatin (23.5%) were the most frequently prescribed statins and amounted to an average simvastatin equivalent of 52 mg/d. Attainment rates of low-density lipoprotein cholesterol (LDL-C) and of non-high-density lipoprotein cholesterol goals were as low as 27% and 33%, respectively. Although there was a significant improvement of LDL-C from 2010 to 2017 (mean LDL-C 110 vs 80 mg/dL, P < .0001 for trend), attainment remained poor, that is, only 42% in 2016 and 45% in 2017 achieved the <70 mg/dL goal. CV mortality was significantly lower (4% vs 11%, P < .01) in statin-treated patients over a median follow-up period of 50 +/- 26 months. CONCLUSION: There is a remarkable undertreatment of LDL-C and non-high density lipoprotein cholesterol in patients with symptomatic PAD, although LDL-C decreased significantly from 2010 to 2017. As statin treatment was associated with a reduced CV mortality rate, our findings call for an increased awareness in clinical lipidology regarding symptomatic PAD patients. PMID- 29574072 TI - Recovery of lipid metabolic alterations in hepatitis C patients after viral clearance: Incomplete restoration with accelerated omega-oxidation. AB - BACKGROUND: How hepatitis C virus (HCV)-associated lipid metabolic alterations recover after sustained virological response (SVR) remains elusive. OBJECTIVE: The aforementioned recovery pattern was investigated. METHODS: In a prospective cohort study of 438 chronic hepatitis C (CHC) patients with SVR after anti-HCV therapy, 164 sex- and age-matched genotype I (G1) and G2 patients underwent paired-serum liquid chromatography-tandem mass spectrometry analyses before and 24 weeks after therapy. Subjects without CHC served as controls (n = 100). RESULTS: CHC patients had lower baseline lipid levels than controls. Among CHC patients, pre-therapy total cholesterol levels were positively associated with HCV RNA levels; G1 patients had higher pre-therapy HCV RNA levels than G2 patients. Repeated measures analysis of variance of CHC patients showed that lathosterol, lanosterol, total hydroxysphingomyelin, and total phosphatidylcholines levels, and total dicarboxyacylcarnitine/total acylcarnitine (indicators of omega-oxidation) and pre-beta-lipoprotein ratios elevated 24 weeks after therapy compared with the levels before therapy. Levels of total lysophosphatidylcholines and alpha- and beta-lipoprotein ratios decreased. Subgroup analyses showed elevated 7-dehydrocholesterol and lanosterol levels, particularly in G2 and male patients, who had broader spectra of altered phosphatidylcholines and acylcarnitines than G1 and female patients, respectively. Compared with controls, CHC patients had higher post-therapy levels of total lysophosphatidylcholines and hydroxysphingomyelins and ratios of total dicarboxyacylcarnitines/total acylcarnitines but lower cholesterol levels. CONCLUSIONS: At 24 weeks after therapy, accelerated cholesterol biosynthesis, hepatic lipid export, omega-oxidation, and decreased systemic inflammation were noted in CHC patients with SVR, with greater efficiency in G2 and male patients. Regardless, HCV-associated lipid metabolic alterations required >24 weeks for restoration or were incompletely reversible after SVR. PMID- 29574073 TI - Selective prescribing of statins and the risk of mortality, hospitalizations, and falls in aged care services. AB - BACKGROUND: Compared to randomized controlled trials, nonexperimental studies often report larger survival benefits but higher rates of adverse events for statin use vs nonuse. OBJECTIVE: We compared characteristics of statin users and nonusers living in aged care services and evaluated the relationships between statin use and all-cause mortality, all-cause and fall-related hospitalizations, and number of falls during a 12-month follow-up. METHODS: A prospective cohort study of 383 residents aged >=65 years was conducted in six Australian aged care services. Data were obtained from electronic medical records and medication charts and through a series of validated assessments. RESULTS: The greatest differences between statin users and nonusers were observed in activities of daily living, frailty, and medication use (absolute standardized difference >0.40), with users being less dependent and less frail but using a higher number of medications. Statin use was associated with a decreased risk of all-cause mortality (adjusted hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.37 0.93) and hospitalizations (HR 0.67, 95% CI 0.46-0.98). After exclusion of residents unable to sit or stand, statin use was associated with a nonsignificant increase in the risk of fall-related hospitalizations (HR 1.47, 95% CI 0.80-2.68) but with a lower incidence of falls (incidence rate ratio 0.67, 95% CI 0.47 0.96). CONCLUSIONS: The observed associations between statin use and the outcomes may be largely explained by selective prescribing and deprescribing of statins and variation in likelihood of hospitalization based on consideration of each resident's clinical and frailty status. Randomized deprescribing trials are needed to guide statin prescribing in this setting. PMID- 29574074 TI - Prevalence, management, and outcomes of familial hypercholesterolemia in patients with acute coronary syndromes in the Arabian Gulf. AB - BACKGROUND: Information on the epidemiology of familial hypercholesterolemia (FH) in the Arabian Gulf region, which has an elevated rate of consanguinity and type II diabetes, is scarce. OBJECTIVES: To assess the prevalence of FH, its management, and impact on atherosclerotic cardiovascular disease (ASCVD) outcomes in a multicenter cohort of Arabian Gulf patients with acute coronary syndrome (ACS). METHODS: Patients (N = 3224) hospitalized with ACS were studied. FH was diagnosed using the Dutch Lipid Clinic Network criteria. A composite endpoint of nonfatal myocardial infarction, stroke, transient ischemic attack, and mortality between the "probable/definite" and the "unlikely" FH patients was assessed after 1 year. Analyses were performed using univariate and multivariate statistical techniques. RESULTS: At admission, the proportion of "probable/definite", "possible", and "unlikely" FH in ACS patients was 3.7% (n = 119), 28% (n = 911), and 68% (n = 2194), respectively. Overall, 54% (n = 1730) of patients had diabetes, whereas 24% (n = 783) were current smokers. The "probable/definite" FH group was younger (50 vs 63 years; P < .001), had a greater prevalence of early coronary disease (38% vs 8.8%; P < .001), and previous statin use (87% vs 57%; P < .001) when compared with the "unlikely" FH group. After 1 year, the "probable/definite" FH cohort had worse lipid control (13% vs 23%; P < .001) and presented with a greater association with the composite ASCVD endpoint when compared with the "unlikely" FH group (odds ratio: 1.85; 95% confidence interval: 1.01-3.38; P = .047) after multivariable adjustment. CONCLUSIONS: In Arabian Gulf citizens, FH was common in ACS patients, was undertreated, and was associated with a worse 1-year prognosis.

AB - The myokine irisin can cross the blood brain barrier and act as a neurokine to protect brain function during endurance exercise. However, the mechanism of transport from the blood to cerebrospinal fluid is unknown. Irisin has been detected in rodent and human brain and human cerebrospinal fluid by using commercial antibodies and enzyme linked immunosorbent assay kits. However, as human FNDC5 has an atypical translation start codon, some studies have questioned the specificity of commercial antibodies. Recently, human irisin was identified and quantitated in plasma by using mass spectrometry. We investigated whether there was irisin in human cerebrospinal fluid and an irisin concentration gradient between in human cerebrospinal fluid and paired plasma. An irisin peptide was identified and quantitated by using mass spectrometry with control peptides enriched with heavy stable isotopes as internal standards. Quantitative mass spectrometry identified the presence of irisin in human cerebrospinal fluid. The internal irisin peptides were modified to the deamidated asparagine form after deglycosylation. The unmodified internal irisin peptides were not found in CSF and irisin concentration was approximately 0.26-1.86 ng/ml in men over 80 years of age with various diseases. However, the parallel reaction monitoring (PRM) elution profiles of both modified and unmodified internal irisin peptides were not found in paired plasma samples. These data unequivocally demonstrated the presence of the glycosylated form of irisin in human cerebrospinal fluid. There were significant individual differences in men over 80 years of age with diseases. However, irisin was not detected in plasma samples by using mass spectrometry. PMID- 29574075 TI - Relationship between "LDL-C", estimated true LDL-C, apolipoprotein B-100, and PCSK9 levels following lipoprotein(a) lowering with an antisense oligonucleotide. AB - BACKGROUND: The laboratory measurement of "low-density lipoprotein cholesterol (LDL-C)" includes the cholesterol content of lipoprotein(a) (Lp(a)-C). OBJECTIVE: To estimate the "true" LDL-C in relation to changes in apolipoprotein B-100 (apoB 100) and assess changes in proprotein convertase subtilisin/kexin 9 (PCSK9) levels in patients with elevated Lp(a) treated with IONIS-APO(a)Rx. METHODS: A pooled placebo group (n = 29), and cohort A (n = 24, baseline Lp(a) 50-175 mg/dL) and cohort B (n = 8, baseline Lp(a) > 175 mg/dL) treated with IONIS-APO(a)Rx were studied. Lp(a) particle number, ultracentrifugation-measured "LDL-C", apoB-100, total PCSK9, and lipoprotein-associated PCSK9 (PCSK9-Lp(a), PCSK9-apoB, PCSK9 apoAI) were measured. Lp(a)-cholesterol (Lp(a)-C) and LDL-C corrected for Lp(a)-C (LDL-Ccorr) were calculated. RESULTS: Baseline mean (standard deviation) "LDL-C" was 120 (42), 128 (45), and 112 (39) mg/dL in placebo, cohorts A and B, respectively, whereas LDL-Ccorr was 86 (48), 96 (43), and 57 (37) mg/dL (P < .001 compared with placebo), representing 28%, 25%, and 50% lower levels than "LDL-C". Following IONIS-APO(a)Rx treatment at day 85/99, Lp(a) particle number and Lp(a) C decreased -66.8% and -71.6%, apoB-100 -10.3% and -17.5%, "LDL-C" -11.8% and 22.7%, (P < .001 for all vs placebo), whereas LDL-Ccorr increased +10.4% (P = .66) and +49.9% (P < .001) in cohorts A and B, respectively. Total PCSK9 did not change but PCSK9-Lp(a) decreased with IONIS-APO(a)Rx vs placebo (-39.0% vs +8.4%, P < .001). CONCLUSION: LDL-Ccorr is lower than laboratory "LDL-C" in patients with elevated Lp(a). Following apolipoprotein(a) inhibition and decline in Lp(a) and Lp(a)-C, the decline in apoB-100 is consistent with the notion that LDL devoid of apo(a) is cleared faster than Lp(a). These types of analyses may provide insights into the mechanisms of drugs affecting Lp(a) levels in clinical trials. PMID- 29574077 TI - Wheat amylase-trypsin inhibitors exacerbate intestinal and airway allergic immune responses in humanized mice. AB - BACKGROUND: Amylase-trypsin inhibitors (ATIs) in wheat and related cereals are potent activators of myeloid innate immune cells via engagement of TLR4. Furthermore, ATIs have been shown to serve as adjuvants in experimental intestinal inflammatory diseases. OBJECTIVE: The aim of this study was to analyze whether ATIs are also modifiers of allergic inflammation. METHODS: Therefore, CD4+ T cells from donors sensitized to grass or birch pollen were stimulated with autologous allergen-pulsed dendritic cells in the presence or absence of ATIs or the control storage protein zein from corn. To analyze allergen-induced gut and lung inflammation, immunodeficient mice were engrafted with PBMCs from these allergic donors plus the respective allergen, and fed with selected diets. Three weeks later, inflammation was induced by rectal or intranasal allergen challenge and monitored by mini endoscopy or airway hyperreactivity, respectively. RESULTS: Allergen-specific T-cell proliferation and cytokine production was significantly exacerbated by ATIs and not by zein. In vivo, allergen-specific human IgE level was strongly elevated in sera of mice receiving an ATI-containing diet compared with mice that were fed gluten-free and thus ATI-free diet. Importantly, allergen induced IgE-dependent colitis and airway hyperreactivity were also enhanced in ATI-fed mice. Gut inflammation was further increased in mice receiving an additional ATI injection and even detectable in the absence of the aeroallergen, whereas zein had no such effect. Injection of anti-human TLR4 mAbs or the anti human IgE mAb omalizumab completely abolished ATI-induced allergic inflammation. CONCLUSIONS: These results underline that wheat ATIs are important nutritional activators and adjuvants of allergy, which might be exploited for nutritional therapeutic strategies. PMID- 29574078 TI - A novel dressing for the combined delivery of platelet lysate and vancomycin hydrochloride to chronic skin ulcers: Hyaluronic acid particles in alginate matrices. AB - The aim of the present work was to develop a medication allowing for the combined delivery of platelet lysate (PL) and an anti-infective model drug, vancomycin hydrochloride (VCM), to chronic skin ulcers. A simple method was set up for the preparation of hyaluronic acid (HA) core-shell particles, loaded with PL and coated with calcium alginate, embedded in a VCM containing alginate matrix. Two different CaCl2 concentrations were investigated to allow for HA/PL core-shell particle formation. The resulting dressings were characterized for mechanical and hydration properties and tested in vitro (on fibroblasts) and ex-vivo (on skin biopsies) for biological activity. They were found of sufficient mechanical strength to withstand packaging and handling stress and able to absorb a high amount of wound exudate and to form a protective gel on the lesion area. The CaCl2 concentration used for shell formation did not affect VCM release from the alginate matrix, but strongly modified the release of PGFAB (chosen as representative of growth factors present in PL) from HA particles. In vitro and ex vivo tests provided sufficient proof of concept of the ability of dressings to improve skin ulcers healing. PMID- 29574079 TI - New fluorescence-based high-throughput screening assay for small molecule inhibitors of tyrosyl-DNA phosphodiesterase 2 (TDP2). AB - Tyrosyl-DNA phosphodiesterase 2 (TDP2) repairs topoisomerase II (TOP2) mediated DNA damages and causes resistance to TOP2-targeted cancer therapy. Inhibiting TDP2 could sensitize cancer cells toward TOP2 inhibitors. However, potent TDP2 inhibitors with favorable physicochemical properties are not yet reported. Therefore, there is a need to search for novel molecular scaffolds capable of inhibiting TDP2. We report herein a new simple, robust, homogenous mix-and-read fluorescence biochemical assay based using humanized zebrafish TDP2 (14M_zTDP2), which provides biochemical and molecular structure basis for TDP2 inhibitor discovery. The assay was validated by screening a preselected library of 1600 compounds (Z' >= 0.72) in a 384-well format, and by running in parallel gel-based assays with fluorescent DNA substrates. This library was curated via virtual high throughput screening (vHTS) of 460,000 compounds from Chembridge Library, using the crystal structure of the novel surrogate protein 14M_zTDP2. From this primary screening, we selected the best 32 compounds (2% of the library) to further assess their TDP2 inhibition potential, leading to the IC50 determination of 10 compounds. Based on the dose-response curve profile, pan-assay interference compounds (PAINS) structure identification, physicochemical properties and efficiency parameters, two hit compounds, 11a and 19a, were tested using a novel secondary fluorescence gel-based assay. Preliminary structure-activity relationship (SAR) studies identified guanidine derivative 12a as an improved hit with a 6.4-fold increase in potency over the original HTS hit 11a. This study highlights the importance of the development of combination approaches (biochemistry, crystallography and high throughput screening) for the discovery of TDP2 inhibitors. PMID- 29574080 TI - Dose- and time-dependent pharmacokinetics of apigenin trimethyl ether. AB - Apigenin trimethyl ether (5,7,4'-trimethoxyflavone, ATE), one of the key polymethoxyflavones present in black ginger (rhizome of Kaempferia parviflora) possesses various health-promoting activities. To optimize its medicinal application, the pharmacokinetics of ATE was assessed in Sprague-Dawley rats with emphases to identify the impacts from dose and repeated dosing on its major pharmacokinetic parameters. Plasma ATE levels were monitored by liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Upon single intravenous administration (2 mg/kg), plasma levels of ATE declined through an apparent first-order process while dose-escalation to 4 and 8 mg/kg led to its non-linear disposition, which could be described by the Michaelis-Menten model. Similarly, dose-dependent oral pharmacokinetics was confirmed and when the dose was escalated from 5 to 15 and 45 mg/kg, much longer mean residence time (MRT0 >last), higher dose-normalized maximal plasma concentration (Cmax/Dose) and exposure (AUC/Dose) were observed at 15 and/or 45 mg/kg. One-week daily oral administration of ATE at 15 mg/kg caused its accelerated elimination and the plasma exposure (AUC) after intravenous (2 mg/kg) and oral administration (15 mg/kg) dropped ~40 and 60%, respectively. As ATE displayed both dose- and time dependent pharmacokinetics, caution is needed in the medicinal applications of ATE and/or black ginger. PMID- 29574081 TI - Effects of enzymatic degradation on dynamic mechanical properties of the vitreous and intravitreal nanoparticle mobility. AB - Intravitreal mobility of nanocarriers may have implications on the efficacy of the encapsulated drug in the treatment of vitreo-retinal diseases, with any changes in the integrity of the vitreous microstructure influencing nanoparticle biodistribution. This study investigated enzymatically digested vitreous models to mimic the aging eye. Collagenase, hyaluronidase, or trypsin was employed to selectively digest the structural components of the vitreous. Physical properties of digested bovine vitreous were initially assessed via texture analysis and oscillatory shear testing. Morphological changes in bovine vitreous microstructure were visualized by scanning electron microscopy and diffusion dynamics of hyaluronic acid coated nanoparticles through degraded porcine and bovine vitreous were examined using fluorescence spectroscopy and multiple particle tracking microscopy, respectively. After enzymatic treatment, the vitreous liquefied and its dynamic mechanical properties significantly changed with a decrease in stiffness and an increase in damping capacity. Micrographs confirmed specific digestion of each of the structural vitreous components. Furthermore, enzymatic degradation reduced steric hindrance and enhanced convective flow within the vitreous, resulting in increased intravitreal nanoparticle mobility which could alter the drug pharmacokinetics. PMID- 29574083 TI - An in vitro and in silico identification of antibiofilm small molecules from seawater metaclone SWMC166 against Vibrio cholerae O1. AB - This study aimed to determine the antibiofilm activity of seawater microbes against Vibrio cholerae (VCO1) through functional metagenomics approach. A metagenomic library was constructed from Palk Bay seawater and the library was screened to identify the biofilm inhibitory metaclone. Metaclone SWMC166 (harbouring ~30 kb metagenomic insert) was found to exhibit antibiofilm activity against VCO1. The biofilm inhibitory potential of partially purified ethyl acetate extract of SWMC166 (EA166) was further evaluated through microscopic studies and biochemical assays. Further, EA166 treated VCO1 divulged up regulation of genes involved in high cell density-mediated quorum sensing (QS) pathway which was analysed by real-time PCR. In order to identify the genes of interest (within ~30 kb insert), subcloning was performed through shotgun approach. Small molecules from positive subclones SC5 and SC8 were identified through HRLC-MS analysis. Resulted small molecules were docked against QS receptors of V. cholerae to identify the bioactive metabolites. Docking studies revealed that totally seven metabolites were able to interact with QS receptors that can possibly trigger the QS cascade and sequentially inhibit the biofilm formation and virulence factors of VCO1.

PMID- 29574085 TI - Combined measurement of plasma cystatin C and low-density lipoprotein cholesterol: A valuable tool for evaluating progressive supranuclear palsy. AB - INTRODUCTION: Progressive supranuclear palsy (PSP) was previously thought as a cause of atypical Parkinsonism. Although Cystatin C (Cys C) and low-density cholesterol lipoprotein-C (LDL-C) are known to play critical roles in Parkinsonism, it is unknown whether they can be used as markers to distinguish PSP patients from healthy subjects and to determine disease severity. METHODS: We conducted a cross-sectional study to determine plasma Cys C/HDL/LDL-C levels of 40 patients with PSP and 40 healthy age-matched controls. An extended battery of motor and neuropsychological tests, including the PSP-Rating Scale (PSPRS), the Non-Motor Symptoms Scale (NMSS), Geriatric Depression Scale (GDS) and Mini-Mental State Examination (MMSE), was used to evaluate the disease severity. Receiver operating characteristic (ROC) curves were adopted to assess the prognostic accuracy of Cys C/LDL-C levels in distinguishing PSP from healthy subjects. RESULTS: Patients with PSP exhibited significantly higher plasma levels of Cys C and lower LDL-C. The levels of plasma Cys C were positively and inversely correlated with the PSPRS/NMSS and MMSE scores, respectively. The LDL-C/HDL-C ratio was positively associated with PSPRS/NMSS and GDS scores. The ROC curve for the combination of Cys C and LDL-C yielded a better accuracy for distinguishing PSP from healthy subjects than the separate curves for each parameter. CONCLUSIONS: Plasma Cys C and LDL-C may be valuable screening tools for differentiating PSP from healthy subjects; while they could be useful for the PSP intensifies and severity evaluation. A better understanding of Cys C and LDL-C may yield insights into the pathogenesis of PSP. PMID- 29574087 TI - Factors associated with advanced-stage Merkel cell carcinoma at initial diagnosis and the use of radiation therapy: Results from the National Cancer Database. AB - BACKGROUND: The stage of disease at initial diagnosis and the use of radiation therapy (RT) are important determinants of survival in patients with Merkel cell carcinoma (MCC). OBJECTIVE: To define factors that are associated with advanced stage MCC at the time of initial diagnosis and the use of RT. METHODS: Cross sectional, retrospective analysis of patients with MCC registered in the National Cancer Database during the period from 2004 to 2013. RESULTS: A total of 11,917 patients were identified; 3152 and 4586 patients were excluded from the staging and RT analyses, respectively, because of lack of available data. African American ethnicity (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.06 2.10; P = .023), lack of medical insurance (OR, 2.15; 95% CI, 1.40-3.30; P < .001), Charlson-Deyo comorbidity score of at least 1 (OR, 1.21; 95% CI, 1.09 1.34; P < .001), residence more than 26 miles from a treatment facility (OR, 1.18; 95% CI, 1.03-1.35; P = .015), tumor located on the lower limb/hip (OR, 1.59; 95% CI, 1.42-1.78; P < .001) or trunk (OR, 2.05; 95% CI, 1.81-2.33; P < .001), and poorly (OR, 2.57; 95% CI, 1.13-5.82; P = .024) or undifferentiated (OR, 3.11; 95% CI, 1.36-7.15; P = .007) tumor histology predicted advanced-stage MCC at the time of initial diagnosis. The use of RT was associated with Native American ethnicity (OR, 5.04; 95% CI, 1.10-22.99; P = .037), tumor size between 1.5 and 2.7 cm (OR, 1.27; 95% CI, 1.10-1.47; P = .001), electing not to have surgery (OR, 2.77; 95% CI, 1.90-4.03; P < .001), positive postsurgical margins (OR, 1.39; 95% CI, 1.18-1.63; P < .001), and receiving treatment at a comprehensive cancer program (OR, 1.25; 95% CI, 1.03-1.50; P = .020). LIMITATIONS: Retrospective design limits generalizability of the results, and precise details of RT regimens utilized were not available. CONCLUSIONS: A number of factors are associated with advanced-stage MCC at initial diagnosis and the use of RT. Health care models should account for these factors, and efforts should be directed toward improving those that are modifiable. PMID- 29574082 TI - Impact of sex steroids and reproductive stage on sleep-dependent memory consolidation in women. AB - Age and sex are two of the three major risk factors for Alzheimer's disease (ApoE e4 allele is the third), with women having a twofold greater risk for Alzheimer's disease after the age of 75 years. Sex differences have been shown across a wide range of cognitive skills in young and older adults, and evidence supports a role for sex steroids, especially estradiol, in protecting against the development of cognitive decline in women. Sleep may also be a protective factor against age related cognitive decline, since specific electrophysiological sleep events (e.g. sleep spindle/slow oscillation coupling) are critical for offline memory consolidation. Furthermore, studies in young women have shown fluctuations in sleep events and sleep-dependent memory consolidation during different phases of the menstrual cycle that are associated with the levels of sex steroids. An under appreciated possibility is that there may be an important interaction between these two protective factors (sex steroids and sleep) that may play a role in daily fluctuations in cognitive processing, in particular memory, across a woman's lifespan. Here, we summarize the current knowledge of sex steroid dependent influences on sleep and cognition across the lifespan in women, with special emphasis on sleep-dependent memory processing. We further indicate gaps in knowledge that require further experimental examination in order to fully appreciate the complex and changing landscape of sex steroids and cognition. Lastly, we propose a series of testable predictions for how sex steroids impact sleep events and sleep-dependent cognition across the three major reproductive stages in women (reproductive years, menopause transition, and post-menopause). PMID- 29574086 TI - Cerebral gray matter volume losses in essential tremor: A case-control study using high resolution tissue probability maps. AB - INTRODUCTION: Essential tremor (ET) is increasingly recognized as a multi dimensional disorder with both motor and non-motor features. For this reason, imaging studies are more broadly examining regions outside the cerebellar motor loop. Reliable detection of cerebral gray matter (GM) atrophy requires optimized processing, adapted to high-resolution magnetic resonance imaging (MRI). We investigated cerebral GM volume loss in ET cases using automated segmentation of MRI T1-weighted images. METHODS: MRI was acquired on 47 ET cases and 36 controls. Automated segmentation and voxel-wise comparisons of volume were performed using Statistical Parametric Mapping (SPM) software. To improve upon standard protocols, the high-resolution International Consortium for Brain Mapping (ICBM) 2009a atlas and tissue probability maps were used to process each subject image. Group comparisons were performed: all ET vs. Controls, ET with head tremor (ETH) vs. Controls, and severe ET vs. Controls. An analysis of variance (ANOVA) was performed between ET with and without head tremor and controls. Age, sex, and Montreal Cognitive Assessment (MoCA) score were regressed out from each comparison. RESULTS: We were able to consistently identify regions of cerebral GM volume loss in ET and in ET subgroups in the posterior insula, superior temporal gyri, cingulate cortex, inferior frontal gyri and other occipital and parietal regions. There were no significant increases in GM volume in ET in any comparisons with controls. CONCLUSION: This study, which uses improved methodologies, provides evidence that GM volume loss in ET is present beyond the cerebellum, and in fact, is widespread throughout the cerebrum as well. PMID- 29574088 TI - A 10-point plan to demonstrate the value of dermatology in the health care system. AB - In May 2017, the American Academy of Dermatology convened a Dermatology Specialty Summit, with representatives from 15 dermatology specialty societies, the American Board of Dermatology, and the Coalition of Skin Diseases in attendance. The Summit's goal was to identify opportunities to address and enhance the perception of dermatology in the House of Medicine, the role of data in the changing health care environment, and access to dermatologic care. Summit participants collectively identified a list of 10 action items that address opportunities in these areas of concern. These include active participation in the House of Medicine, increased interaction with and education of our primary care colleagues, efforts to support DataDerm, and creative ways to improve access. PMID- 29574089 TI - Trends in phototherapy utilization among Medicare beneficiaries in the United States, 2000 to 2015. AB - BACKGROUND: Phototherapy is a cost-effective treatment for many dermatoses, yet the emergence of alternative therapies such as biologics led many to think that phototherapy utilization was declining. OBJECTIVE: To characterize national, historical phototherapy utilization and costs among Medicare beneficiaries. METHODS: Longitudinal analysis of the Medicare Part B National Summary Data File from 2000 to 2015 for phototherapy billing codes. Geographic distribution of clinics and provider type obtained from the Medicare Provider Utilization and Payment Data for 2012 to 2015. RESULTS: The overall volume of phototherapy services billed to Medicare from 2000 to 2015 increased by 5% annually, from 334,670 to 692,093. Ultraviolet B therapy comprised 77% of phototherapy volume, utilization of psoralen plus ultraviolet A therapy declined by 9% annually, and excimer laser services grew by 29% annually. The number of phototherapy clinics is increasing but remains concentrated in only 11% of US counties. Between 2012 and 2015, dermatologists accounted for 92% of phototherapy volume. LIMITATIONS: Commercial payers and institutional claims (hospital-based physicians) are excluded. Clinical indications for phototherapy use are not reported in this database. CONCLUSION: Phototherapy utilization has grown, though the service mix has shifted toward ultraviolet B and laser excimer therapy and away from psoralen plus ultraviolet A therapy. Dermatologists manage most phototherapy. Uneven geographic distribution of phototherapy clinics limits access in nonurban areas, and further evaluation is needed to determine its impact on rural communities.

AB - BACKGROUND & AIMS: The presence of specific single nucleotide polymorphisms (SNPs) can be used to calculate an individual's risk for colorectal cancer (CRC), called a genetic risk score (GRS). We investigated whether GRS can identify individuals with clinically relevant neoplasms in a screening colonoscopy population. METHODS: We derived a GRS based on 48 SNPs associated with CRC, identified in a comprehensive literature search. We obtained genetic data from 1043 participants (50-79 years old) in a screening colonoscopy study in Germany, recruited from 2005 through 2013 (294 with advanced neoplasms, 249 with non advanced adenoma (NAAs), and 500 without neoplasms). Each participant was assigned a GRS by aggregating their risk alleles (0, 1, or 2). Risk of advanced neoplasms and NAA according to GRS was calculated by multiple logistic regression. Risk advancement periods were calculated. We replicated our findings using data from a subset of the Tennessee Colorectal Polyp Study. RESULTS: An increased GRS was associated with higher prevalence of advanced neoplasms, but not NAAs. Participants in the middle and upper tertiles of GRS had a 2.2-fold and 2.7-fold increase in risk, respectively, of advanced neoplasms compared to those in the lower tertile. Adjusted odds ratios (ORs) were 1.09 (95% confidence interval [CI], 0.76-1.57) for NAA in the middle tertile and 1.05 (95% CI, 0.70 1.55) for NAA in the upper tertile. The ORs were largest for proximal advanced neoplasms for participants in the middle tertile (OR, 3.55; 95% CI 1.85-6.82) and the upper tertile (OR, 3.61; 95% CI 1.84-7.10). The risk advancement period for medium vs low GRS was 13.4 years (95% CI 4.8-22.0) and for high vs low GRS was 17.5 years (95% CI, 7.8-27.3). CONCLUSIONS: In a genetic analysis of participants in a CRC screening study in Germany, an increased GRS (based on CRC-associated SNPs) was associated with increased prevalence of advanced neoplasms. These findings might be used in defining risk-adapted screening ages. PMID- 29574092 TI - Plectin-1 Targeted Dual-modality Nanoparticles for Pancreatic Cancer Imaging. AB - BACKGROUND: Biomarker-targeted molecular imaging holds promise for early detection of pancreatic cancer. The aim of this study was to design and evaluate a plectin-1 targeted multi-functional nanoparticle probe for pancreatic cancer imaging. METHODS: 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine-N amino(polyethylene glycol) (DSPE-PEG-NH2)-modified superparamagnetic iron oxide (Fe3O4) nanoparticles (SPION) were conjugated with plectin-1 antibody and/or Cy7 to create the multi-functional targeted nanoparticle targeted probe (Plectin SPION-Cy7) or non-targeted probe (SPION-Cy7). Pancreatic carcinoma cell lines expressing plectin-1 were cultured with the targeted or control probes and then were imaged using confocal laser scanning microscopy and magnetic resonance imaging (MRI). Accumulations of the nanoparticles in pancreatic tumor xenografted mice were determined by MRI and fluorescence imaging. RESULTS: In vitro optical imaging and MRI showed that the targeted nanoparticles were highly accumulated in MIAPaCa2 and XPA-1 carcinoma cells but not in non-carcinoma MIN6 cells, which was further confirmed by Prussian blue staining. In vivo MRI showed a significant T2 signal reduction. Prussian blue staining further confirmed that the plectin-1 targeted nanoparticles were highly accumulated in the tumor mass but not in normal pancreatic tissues, or in the liver and kidney, and few nanoparticles were observed in the tumors of mice injected with SPION-Cy7. CONCLUSIONS: Our data demonstrate that plectin-1 targeted fluorescence and MR dual-functional nanoparticle can visualize pancreatic cancer, and it has great potential to be used with various imaging devices for pancreatic cancer detection. PMID- 29574093 TI - Alisma canaliculatum ethanol extract suppresses inflammatory responses in LPS stimulated macrophages, HCl/EtOH-induced gastritis, and DSS-triggered colitis by targeting Src/Syk and TAK1 activities. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Alisma canaliculatum A.Braun & C.D.Bouche, distributed in Korea, Japan, China, and Taiwan, is a traditional medicine. In particular, the stem and root of Alisma canaliculatum A.Braun & C.D.Bouche are prescribed to relieve various inflammatory symptoms resulting from nephritis, cystitis, urethritis, and dropsy. AIM OF STUDY: However, the curative mechanism of Alisma canaliculatum A.Braun & C.D.Bouche with respect to inflammatory symptoms is poorly understood. In this study, the curative roles of this plant in various inflammatory conditions as well as its inhibitory mechanism were aimed to examine using an ethanol extract (Ac-EE). MATERIALS AND METHODS: Anti inflammatory effects of Ac-EE were evaluated in lipopolysaccharide (LPS)-induced macrophages in vitro and HCl/EtOH-stimulated mouse model of gastritis and DSS treated mouse model of colitis. To determine the potentially active anti inflammatory components in this extracts, we employed HPLC. We also used kinase assays, reporter gene assay, immunoprecipitation analysis and target enzyme overexpressing cell analysis to analyze the molecular mechanisms and the target molecules. RESULTS: This extract dose-dependently inhibited the production of nitric oxide (NO) and prostaglandin E2 (PGE2) from RAW264.7 cells and peritoneal macrophages activated by lipopolysaccharide (LPS). Additionally, Ac-EE ameliorated inflammatory symptoms resulting from gastritis and colitis. Ac-EE down-regulated the mRNA levels of inducible NO synthase (iNOS), tumor necrosis factor (TNF)-alpha, and cyclooxygenase-2 (COX-2). Ac-EE also blocked the nuclear translocation of nuclear factor (NF)-kappaB and activator protein (AP)- 1 in LPS stimulated RAW264.7 cells. By analyzing the target signaling molecules activating these transcription factors, we found that Src and Syk, as well as molecular association between TAK1 and mitogen-activated protein kinase kinase 4/7 (MKK4/7), were targeted by Ac-EE. CONCLUSIONS: Our data suggest that the Ac-EE NF kappaB/AP-1-targeted anti-inflammatory potential is mediated by suppression of Src and Syk as well as the complex formation between TAK1 and its substrate proteins MKK4/7. PMID- 29574094 TI - Regulation of human dendritic cell immune functions by ion channels. AB - Dendritic cells (DCs) are highly specialized antigen-presenting cells (APCs) able to induce both specific immunity and immune tolerance. Using information gathered from the tissue where they reside, DCs adjust their functional activity to ensure that protective immunity is favoured while unwanted or exaggerated immune responses are prevented. The remarkable ability of these cells to induce, enhance and orient the immune response, while at the same time maintaining self tolerance, makes them key players in the immune system. Despite the fact that the role of Ca2+ has been clearly established in human DC functions, the link between ion homeostasis, mainly Ca2+, and DC functions is not fully understood. After all, a growing number of works clearly show the role of SOCE and associated channels in the maturation step, and those of K+ channels in migration. This review highlights the key papers published over the past few years and summarizes prospects for the near future. PMID- 29574095 TI - Changes in uptake and cost of long-acting reversible contraceptive devices following the introduction of a new low-cost levonorgestrel IUD in Utah's Title X clinics: a retrospective review. AB - OBJECTIVE: The objective was to assess changes in long-acting reversible contraceptive (LARC) method uptake at Utah's Title X clinics before and after introduction of a new, low-cost levonorgestrel (LNG) 52mg IUD (Liletta(r)). STUDY DESIGN: We conducted a retrospective medical record review of LARC visits occurring at seven Title-X family planning clinics in Utah before the introduction of the low-cost LNG IUD (preintroduction period: 01/01/2014 04/30/2015) and after (postintroduction period: 05/01/2015-03/31/2016). We ran segmented, interrupted time series ordinary least squares regression models using Newey-West standard errors to assess both the change in numbers of women initiating any LARC method and the average payment amount per LARC method. We evaluated both the low-cost LNG IUD and all LARC methods. RESULTS: At the outset of preintroduction period, there were 29.2 [95% confidence interval (CI): 20.1 38.4] monthly LNG IUD insertions. Immediately postintroduction, there was a significant level of increase of 14.4 LNG IUD insertions the first month (95% CI: 2.0-26.8) followed by a significant trend increase each month of 2.4 additional LNG IUD insertions (95% CI: 0.32-4.47). Postintroduction, there was a significant level of remitted-payment decrease from all sources of -$240.43 per LNG IUD (95% CI: -311.02 to 168.87) followed by a significant monthly trend decrease of $23.01 per LNG IUD (95% CI: -32.02 to -13.98). There were minimal changes in uptake and payment of other LARC methods following the introduction of the low cost LNG IUD. CONCLUSIONS: Following introduction of a low-cost LNG IUD at Title X clinics, LNG IUD initiation increased and average payment for the method decreased. IMPLICATIONS: Reducing the cost of LARC methods, both to clinics and to patients, is essential to expanding access. Additional efforts to develop and provide access to low-cost copper IUDs and subdermal implants as well as novel LARC methods should be continued.

AB - OBJECTIVES: The aim of this study is to compare gene expression profiles in RNA isolated from pancreatic ductal juice with the RNA expression profiles of the same genes from matched intra-operative tissue samples from pancreatic tumours. METHODS: Intra-operative sampling of pancreatic juice and collection of matched tissue samples was undertaken in patients undergoing pancreatoduodenectomy for clinically suspected pancreatic cancer and a precursor lesion, main-duct intraductal papillary mucinous neoplasm. RNA was isolated and Poly A PCR was used to globally amplify the RNA. Real-time polymerase chain reaction (RT-PCR) was used to measure expression levels of 17 genes selected from microarray studies. Spearman's rank correlation test was used to examine the relationship of gene expression between pancreatic juice and tissue. The study was approved by Regional Ethics Committee. RESULTS: Mesothelin (MSLN) showed significant correlation (p < 0.008) in expression levels between paired pancreatic juice and tissue samples in pancreas cancer. In intraductal papillary mucinous neoplasms (IPMN), Matrix Metalloproteinase 7 (MMP7), showed significant correlation (p < 0.01) in the expression levels between paired pancreatic juice and tissue samples. CONCLUSION: This study confirms that RNA analysis of paired pancreatic juice and tissue samples and establishment of cDNA using poly A PCR is technically feasible. Application of the technique to non-invasively obtained pancreatic juice during endoscopic assessment of tumours and the use of gene arrays of cancer indicator genes are the next steps in development of this technique. PMID- 29574097 TI - Dynamic changes in hippocampal microglia contribute to depressive-like behavior induced by early social isolation. AB - Depression triggered by early-life stress has begun to attract wide attention due to its severe symptoms and poor treatment outcomes. However, the pathophysiological mechanism for this type of depression remains unclear. Recently, we and others reported that different types of chronic stress induce a significant loss of hippocampal microglia, which is mediated by an initial activation of these microglia. Since early-life stress also promotes microglial activation, we investigated the dynamic changes in hippocampal microglia in mice suffering from depression induced by early social isolation (ESI). Results showed that 8 days of ESI induced depressive-like behaviors in a tail suspension test, forced swim test, sucrose preference test, and open field test, and it also induced a loss and dystrophy of hippocampal microglia. We found that this ESI induced loss of hippocampal microglia was mediated by both microglial activation and apoptosis. This was demonstrated by the following results: (i) 1 day of ESI induced an obvious activation of hippocampal microglia followed by their apoptosis, and (ii) the blockade of the initial activation of hippocampal microglia by minocycline pretreatment suppressed the ESI-induced apoptosis and loss as well as ESI-induced depressive-like behavior. Lipopolysaccharide (LPS) and macrophage colony-stimulating factor (M-CSF), two activators of microglia, almost completely reversed ESI-induced depressive-like behavior by promoting microglial proliferation in the hippocampus. These results reveal an etiological role of hippocampal microglial loss in ESI-induced depression and demonstrate that the restoration of microglial homeostasis in the hippocampus may serve as a therapeutic strategy for depression induced by early-life stress. PMID- 29574098 TI - Inhibition of mitochondrial permeability transition pore opening contributes to cannabinoid type 1 receptor agonist ACEA-induced neuroprotection. AB - Cannabinoid type 1 (CB1) receptor agonist arachidonyl-2-chloroethylamide (ACEA) induces neuroprotection against brain ischemia, and the mechanism, however, is still elusive. In this study, we used bilateral common carotid artery occlusion (BCCAO) in mice and oxygen-glucose deprivation (OGD) in primary cultured neurons to mimic brain ischemic injury, and hypothesized that cannabinoid CB1 receptor agonist ACEA protects ischemic neurons via inhibiting the opening of mitochondrial permeability transition pore (MPTP). In vivo, we found that BCCAO treatment reduced the neurological functions, increased the number of apoptotic neuronal cells and deteriorated the mitochondrial morphology in the ischemic brain tissue. And in vitro, we observed that OGD injury reduced cell viability, mitochondrial function and anti-oxidant SOD2 expression, increased lactate dehydrogenase (LDH), mitochondrial cytochrome C (Cyto C) and apoptosis-inducing factor (AIF) releases, elevated the cell apoptosis and mitochondrial superoxide level. And the CB1 receptor agonist ACEA significantly abolished the BCCAO and OGD-induced neuronal injury above. However, the MPTP opener atractyloside (Atr) markedly reversed the ACEA-induced neuroprotective effects, inhibited the mitochondrial Cyto C and AIF releases and relieved the mitochondrial swelling, but the MPTP inhibitor cyclosporin A (CsA) did not cause significant effects on the ACEA-induced neuroprotection above. These findings indicated that inhibition of MPTP opening may be involved in the cannabinoid CB1 receptor agonist ACEA induced neuroprotection. PMID- 29574099 TI - The Role of Laparoscopic Mini-Gastric Bypass in Management of Metabolic Syndrome. AB - OBJECTIVE: The study was performed to evaluate the technique of laproscopic minigastric bypass for metabolic syndrome patients. STUDY DESIGN: The patients were enrolled in a combined prospective study and had a retrospectively gathered outcome analysis. PATIENT AND METHODS: The study includes thirty patients; 24 females and 6 males suffering from metabolic syndrome with a mean age of 33.15 +/ 10.17 years (range, 20-59), who fulfilled the criteria for bariatric surgery with BMI >35 with associated co-morbidities, all patients underwent laparoscopic mini-gastric bypass. RESULTS: BMI and WC were significantly reduced post operatively; also co-morbidities as DM, hypertension and dyslipidemia were resolved or controlled. The mean operative time was 90 +/- 12.6 min (range, 80 120). No mortality was reported within 30 days of surgery. CONCLUSION: Laparoscopic mini gastric bypass is an effective procedure for the treatment of obesity, HTN, type 2 DM and dyslipidemia, technically feasible, safe operation with a low rate of major postoperative complications. PMID- 29574100 TI - Inhibitory role of the Bm8 protein in the propagation of Bombyx mori nucleopolyhedrovirus. AB - Lepidopteran nucleopolyhedroviruses have distinct viral tissue tropisms in host larvae. We previously identified the Bm8 gene of Bombyx mori nucleopolyhedrovirus (BmNPV), the product of which inhibits viral propagation in the middle silk gland (MSG). However, it is unknown whether this inhibitory function of the Bm8 protein is specific to MSGs. Here we generated a Bm8-disrupted recombinant BmNPV expressing green fluorescent protein (GFP) and examined viral propagation in B. mori cultured cells and larvae. We found that Bm8-disrupted BmNPV produced fewer budded viruses and more occlusion bodies (OBs) than the wild-type virus in both cultured cells and larvae. Microscopic observation of OB production and GFP expression revealed that Bm8 disruption accelerated the progression of viral infection in various larval tissues. Furthermore, quantitative reverse transcription-polymerase chain reaction experiments showed that the loss of Bm8 enhanced viral gene expression in BmNPV-infected larval tissues. These results indicate that the Bm8 protein suppresses viral propagation to varying degrees in each larval tissue, which may establish BmNPV tissue tropisms in B. mori larvae. PMID- 29574101 TI - A novel virus (order Bunyavirales) from stressed redclaw crayfish (Cherax quadricarinatus) from farms in northern Australia. AB - Athtabvirus, a bunya-like virus and chequa iflavirus infect redclaw crayfish (Cherax quadricarinatus) and they may cause mortality reaching 20-40% after about three weeks following transportation stress. Lesions were seen in the muscles of broodstock and juveniles and nerve cords of craylings. Using NextGen sequencing, the whole transcriptomes of a farmed case crayfish and a tank-reared, unaffected crayfish were assembled producing over 500,000 contigs. The average depth of reads was 18 replicates with a range from 15 to 44. The near complete sequences of the large and middle genome segments of a bunya-like virus were detected along with chequa iflavirus. The internal bunya-like motifs; RNA-dependent RNA polymerase on the L segment, and glycoprotein n (Gn) on the M segment were easily identified. In the opposite, positive-sense direction on the M segment, another presumed glycoprotein (glycoprotein c) with a low-density lipoprotein receptor (cysteine-rich) motif was identified by position specific iterated (psi)-BLASTp. The athtabvirus was related to Whenzhou Shrimp Virus 2 (E = 0.0, 43% amino acid identity), an unassigned, -ve sense ssRNA virus, and to peribunyaviruses (E = 10 50-20). In descending order of the number of RNA copies/0.2 mg of tissue, the organs most heavily infected were muscle (9.4 * 106), nerve cord (5.24 * 106), heart (4.07 * 106), gills (3.96 * 106), hepatopancreas (1.58 * 106) and antennal gland (6.6 * 105). Given the tissue tropism (muscle and nerves) of athtabvirus and the original lesions, this virus is implicated in being involved in the mortalities in crayfish after transportation. PMID- 29574102 TI - STATSLAB: An open-source EEG toolbox for computing single-subject effects using robust statistics. AB - Research on robust statistics during the past half century provides concrete evidence that classical hypothesis tests that rely on the sample mean and variance are problematic. Even seemingly minor departures from normality are now known to create major problems in terms of increased error rates and decreased power. Fortunately, numerous robust estimation techniques have been developed that circumvent the need for strict assumptions of normality and equal variances, leading to increased power and accuracy when testing hypotheses. Two robust methods that have been shown to have practical value across a wide range of applied situations are the trimmed mean and percentile bootstrap test. To facilitate the uptake of robust methods into the behavioural sciences, especially when dealing with trial-based data such as EEG, we introduce STATSLAB: An open source EEG toolbox for computing single-subject effects using robust statistics. With the STATSLAB toolbox users can apply the percentile bootstrap test, with trimmed means, to a variety of neural signals including voltages, global field amplitude, and spectral features for both scalp channels and independent components. The toolbox offers a range of analytical strategies and is packaged with a fully functional graphical user interface that includes documentation. PMID- 29574103 TI - Sevoflurane exaggerates cognitive decline in a rat model of chronic intermittent hypoxia by aggravating microglia-mediated neuroinflammation via downregulation of PPAR-gamma in the hippocampus. AB - Postoperative cognitive dysfunction is a common complication associated with anesthesia and surgery. Sevoflurane is a widely used volatile anesthetic in the clinical setting. Preclinical studies show that sevoflurane alone does not appear to cause cognitive dysfunction. Here, we examined whether sevoflurane induces cognitive decline under chronic intermittent hypoxia (CIH) conditions. Rats were exposed to CIH or control for 4 weeks. Two weeks after starting intermittent hypoxia, these animals underwent either 2.6% sevoflurane or vehicle exposure for 4 h. Four weeks after CIH, Morris Water Maze task showed that both groups of CIH rats exhibited significantly longer latency to locate the hidden platform and had shorter dwell-time in the goal quadrant compared with respective controls. Notably, CIH + sevoflurane rats had much higher latency and less dwell-time than CIH + vehicle rats. Molecular studies revealed that pro-inflammatory cytokine expression and activated microglia in the hippocampus were increased in both groups of CIH rats, with greater increases in CIH + sevoflurane rats. No differences in above measured parameters were observed between two control groups. Sevoflurane reduced PPAR-gamma expression and activity in both control and CIH rats. Moreover, activated microglia was positively correlated with proinflammatory cytokine expression and negatively correlated with PPAR-gamma expression and activity in CIH groups. The results suggest that microglia mediated neuroinflammation in the hippocampus plays an important role in the pathogenesis of CIH-associated cognitive dysfunction, and that a moderate duration of sevoflurane exaggerates cognitive decline under CIH conditions by aggravating microglia-mediated neuroinflammation via downregulation of PPAR-gamma in the hippocampus. PMID- 29574104 TI - The Escherichia coli effluxome. AB - Multidrug transporters function in a coordinated mode to provide an essential first-line defense mechanism that prevents antibiotics from reaching lethal concentrations, until a number of stable efficient adaptations occur that allow survival. Single-component efflux transporters remove the toxic compounds from the cytoplasm to the periplasmic space where TolC-dependent transporters expel them from the cell. The close interaction between the two types of transporters ensures handling of a wide range of xenobiotics and prevents rapid leak of the hydrophobic substrates back into the cell. In this review, we discuss the concept of the bacterial effluxome of the Gram-negative Escherichia coli that is the entire set of transporters expressed at a given time, under defined conditions. The process of identification of its members and the elucidation of the nature of the interactions throw a novel light on the roles of transporters in bacterial physiology and drug resistance development. We anticipate that the concept of an effluxome where each member contributes to the removal of noxious chemicals from the cell should contribute to improving the present strategy of searching for transport inhibitors as adjuvants of existing antibiotics and provide novel targets for this urgent undertaking. PMID- 29574105 TI - Increased risk of diabetes development in individuals with weight cycling over 4 years: The Kangbuk Samsung Health study. AB - AIMS: Weight cycling is defined as cyclical loss and gain of weight and recent studies suggest deleterious effects of weight cycling on cardiometabolic health. We aimed to analyze the risk for diabetes development in association with weight cycling over 4 years of follow-up. METHODS: A retrospective study performed in 4,818 non-diabetic participants (mean age 43 years, 78.3% men) in a health screening program in whom serial health examinations were performed in 5 consecutive years from 2010 to 2014. Average successive variability of weight (ASVW) was defined by the amount of body weight change in absolute value between the successive years over 5 years summed and divided by four. The subjects were divided into two groups according to body mass index (BMI), normal weight (<23 kg/m2) and overweight (>=23 kg/m2). RESULTS: Over 4 years, 3.2% developed diabetes. When the subjects were divided into 3 groups according to tertile groups of ASVW, those in the highest tertile showed significantly increased risk for diabetes development compared to those with the lowest tertile {odds ratio (OR) 1.860; 95% CI 1.130-3.063}. When similar analyses were performed according to the 4 groups divided by baseline body weight and ASVW over four years, those who were more than overweight at baseline with high ASVW showed significantly increased risk of diabetes development compared to those had normal weight and low ASVW (OR 2.266; 95% 1.123-4.572). When the subjects were divided into six group according to weight change and ASVW, those with increased weight over 4 years and high ASVW showed the highest risk for diabetes development among the groups compared to those with stable weight and low ASVW over four years (OR 3.660; 95% CI 1.402-9.553). CONCLUSIONS: Those with high ASVW showed significantly increased risk for diabetes development over four years compared with those who had low ASVW. Weight cycling was significantly associated with increased risk for diabetes. PMID- 29574106 TI - Self-reported color-race and genomic ancestry in an admixed population: A contribution of a nationwide survey in patients with type 1 diabetes in Brazil. AB - AIMS: The development of type 1 diabetes (T1D) and its chronic complications may have a genetic background. The primary objective of our study was to characterize the relationship between self-reported color-race and genomic ancestry (GA) in patients with T1D. As secondary objective, we aimed to characterize GA of patients with T1D from different urban geographical regions of Brazil, compared to healthy Brazilian controls from the same regions. METHODS: This was a cross sectional, nationwide survey conducted in 14 public clinics from 10 Brazilian cities. Global and individual GA were inferred using a panel of 46 ancestry informative markers (AIMs) in 1698 T1D patients. Ancestry percentage was compared with published data of Brazilian healthy controls (n = 936) for the same AIMs. RESULTS: A higher median individual European ancestry was observed in T1D patients in comparison to controls 67.8 [31.2] vs. 56.3 [25.7]%, respectively (median [IQR]; p < 0.001). As for self-reported color-race in T1D group, 923 (54.3%) participants reported to be White, 610 (35.9%) Brown, 132 (7.8%) Black, 18 (1.1%) Asian and 15 (0.9%) Indigenous. European GA prevailed in those who self reported as White (74.6%) and Brown (61.1%) and constituted 39.1% in Black self reported patients. CONCLUSIONS: Our study showed that T1D patients presented a higher percentage of European GA than the healthy population. Additionally, European GA was found in a considerable percentage of T1D patients who self reported as non-White. Further studies are necessary to establish the influence of GA in the development of T1D as well its related chronic complications in admixed populations. PMID- 29574107 TI - Evaluation of the impact of a diabetes education eLearning program for school personnel on diabetes knowledge, knowledge retention and confidence in caring for students with diabetes. AB - AIMS: To study the impact of a novel comprehensive eLearning approach in delivering diabetes related education program that includes knowledge and sets of practices to the school personnel in Kuwait to enable them to provide a supportive environment for students with diabetes. METHODS: The program was designed with three components namely; knowledge, skills and recommendations. The diabetes knowledge was delivered through an interactive eLearning program, the effectiveness of which was assessed using diabetes knowledge questionnaires which were deployed pre- and post-course delivery. Additionally, the participants' knowledge retention and confidence in caring for a student with diabetes were evaluated at 6 or 12 months post-intervention. RESULTS: A total of 124 public schools' personnel participated in the program. Post e-Learning delivery, diabetes knowledge increased significantly from baseline (p < 0.0001) and knowledge was retained over 6 and 12 months. Average of overall confidence scores in caring for students with diabetes was 61.86% in all items of care. CONCLUSIONS: Offering eLearning diabetes education for school personnel increases their knowledge which can be retained for up to 12 months and imparts confidence in caring for students with diabetes. This novel approach of delivering diabetes education will help school personnel in managing students with diabetes. PMID- 29574108 TI - Diabetes is associated with increased prevalence of latent tuberculosis infection: Findings from the National Health and Nutrition Examination Survey, 2011-2012. AB - AIMS: We aim to determine the association between prediabetes and diabetes with latent TB using National Health and Nutrition Examination Survey data. METHODS: We performed a cross-sectional analysis of 2011-2012 National Health and Nutrition Examination Survey data. Participants >=20 years were eligible. Diabetes was defined by glycated hemoglobin (HbA1c) as no diabetes (<=5.6% [38 mmol/mol]), prediabetes (5.7-6.4% [39-46 mmol/mol]), and diabetes (>=6.5% [48 mmol/mol]) combined with self-reported diabetes. Latent TB infection was defined by the QuantiFERON(r)-TB Gold In Tube (QFT-GIT) test. Adjusted odds ratios (aOR) of latent TB infection by diabetes status were calculated using logistic regression and accounted for the stratified probability sample. RESULTS: Diabetes and QFT-GIT measurements were available for 4958 (89.2%) included participants. Prevalence of diabetes was 11.4% (95%CI 9.8-13.0%) and 22.1% (95%CI 20.5-23.8%) had prediabetes. Prevalence of latent TB infection was 5.9% (95%CI 4.9-7.0%). After adjusting for age, sex, smoking status, history of active TB, and foreign born status, the odds of latent TB infection were greater among adults with diabetes (aOR 1.90, 95%CI 1.15-3.14) compared to those without diabetes. The odds of latent TB in adults with prediabetes (aOR 1.15, 95%CI 0.90-1.47) was similar to those without diabetes. CONCLUSIONS: Diabetes is associated with latent TB infection among adults in the United States, even after adjusting for confounding factors. Given diabetes increases the risk of active TB, patients with co prevalent diabetes and latent TB may be targeted for latent TB treatment. PMID- 29574109 TI - Comparative Survival following Initial Cytoreductive Nephrectomy versus Initial Targeted Therapy for Metastatic Renal Cell Carcinoma. AB - PURPOSE: The optimal sequence of cytoreductive nephrectomy and targeted therapy of metastatic renal cell carcinoma is unclear. We compared overall survival between patients with metastatic renal cell carcinoma treated with initial cytoreductive nephrectomy with or without subsequent targeted therapy vs initial targeted therapy with or without subsequent cytoreductive nephrectomy. MATERIALS AND METHODS: We evaluated the records of cases in the National Cancer Database diagnosed with metastatic renal cell carcinoma between 2006 and 2013 who were treated with cytoreductive nephrectomy and/or targeted therapy. Receipt of targeted therapy after initial cytoreductive nephrectomy and cytoreductive nephrectomy after initial targeted therapy were evaluated on competing risks analyses. To account for treatment selection bias, inverse probability of treatment weighting was performed based on the propensity to receive initial cytoreductive nephrectomy or initial targeted therapy. Overall survival was compared between the groups by Kaplan-Meier analysis and Cox proportional hazards regression. RESULTS: Of the 15,068 patients included in study 6,731 underwent initial cytoreductive nephrectomy and 8,337 received initial targeted therapy. Six months after initial cytoreductive nephrectomy 48.0% of patients received targeted therapy, of whom 15.3% died after initial cytoreductive nephrectomy prior to targeted therapy. Six months after initial targeted therapy 4.7% of patients underwent cytoreductive nephrectomy, of whom 44.9% died after initial targeted therapy prior to cytoreductive nephrectomy. Initial cytoreductive nephrectomy (OR 2.02, 95% CI 1.69-2.43, p <0.001) and cytoreductive nephrectomy after initial targeted therapy (HR 2.6, 95% CI 1.69-4.01, p <0.001) were more likely to be performed at academic vs community institutions. On inverse probability of treatment weighting analysis initial cytoreductive nephrectomy was associated with improved overall survival compared to initial targeted therapy (median 16.5 vs 9.2 months, HR 0.61, 95% CI 0.59-0.64, p <0.001). CONCLUSIONS: Given the greater likelihood of receiving multimodal therapy and the associated overall survival benefit, these data support cytoreductive nephrectomy as the initial approach to metastatic renal cell carcinoma in appropriate surgical candidates. Continued efforts are warranted to establish the optimal multimodal approach in these patients. PMID- 29574110 TI - Targeted Antimicrobial Prophylaxis Does Not Always Prevent Sepsis after Transrectal Prostate Biopsy. AB - PURPOSE: We compared the effectiveness of targeted prophylaxis to augmented empirical prophylaxis and single agent empirical prophylaxis to prevent sepsis after transrectal prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed the records of transrectal prostate biopsies performed during 3 years at 13 Southern California Kaiser Permanente(r) departments of urology. Targeted prophylaxis was guided by rectal culture bacterial susceptibility for use of a single prophylactic antibiotic while for empirical prophylaxis 1 antibiotic (single agent empirical prophylaxis) or multiple antibiotics (augmented empirical prophylaxis) were given according to the usual practice of the urologist. Sepsis was the primary outcome analyzed. RESULTS: We reviewed 15,236 transrectal prostate biopsy cases. Targeted prophylaxis, single agent empirical prophylaxis and augmented empirical prophylaxis were administered in 26%, 58% and 16% of cases, respectively. The overall incidence of post-biopsy sepsis was 0.64%. On multivariable analysis there was no significant difference in the rate of post biopsy sepsis after targeted prophylaxis compared to empirical prophylaxis (single agent and augmented empirical prophylaxis together) (OR 0.86, 95% CI 0.53 1.41, p = 0.561). However, on subanalysis augmented empirical prophylaxis showed a significantly lower incidence of sepsis than single agent empirical or targeted prophylaxis (OR 0.35, 95% CI 0.16-0.76, p = 0.008). Based on blood and urine cultures 38% of the patients with sepsis after transrectal prostate biopsy had been given the correct prophylactic antibiotic prior to biopsy. On multivariable analysis Asian/Pacific Islander or Hispanic/Latino ethnicity was associated with a higher incidence of harboring fluoroquinolone resistant bacteria on rectal swab cultures. CONCLUSIONS: This large retrospective study showed that augmented empirical prophylaxis was statistically superior to single agent empirical and targeted prophylaxis. Sepsis developed in a significant number of patients despite being given a prophylactic antibiotic to which the sepsis causing bacteria were sensitive. PMID- 29574111 TI - Isolated lateral cervical swelling in a adolescent. PMID- 29574112 TI - Ameloblastic fibrodentinosarcoma and ameloblastic fibro-odontosarcoma: A systematic review. AB - The purpose of the present review was to integrate the available data published on ameloblastic fibrodentinosarcoma (AFDS) and ameloblastic fibro-odontosarcoma (AFOS) into a comprehensive analysis of their clinical/radiologic features. An electronic search was undertaken in July/2017. Eligibility criteria included publications having enough clinical/radiological/histological information to confirm the diagnosis. Seventeen publications (8 AFDS, 9 AFOS) were included. The patients with the two different lesions had a similar mean age. The lesions were both more prevalent in mandibles than in maxillae, all showed bone expansion and similar rates of cortical bone perforation, tooth displacement, and locular appearance at radiological exams. Mean follow-up time was higher for AFDS, and the mean size of the lesions were larger for AFDS, although without a statistically significant difference. None of AFDS recurred, while 2 AFOS recurred. As only few cases of AFDS and AFOS have been reported, additional reports are necessary to add evidence to the study of clinical and radiologic features of these lesions.

PMID- 29574116 TI - Predicting the oxygen cost of walking in hemiparetic stroke patients. AB - OBJECTIVE: To verify the relation between spontaneous walking speed (Sfree) and oxygen cost of walking at Sfree (Cwfree) in post-stroke hemiparetic patients and to test the validity of a prediction model to estimate Cwfree based on Sfree. DESIGN: We included 26 participants (mean age 65.1 years [SD 15.7]) with mild to moderate disability after stroke who walked at Sfree using mobility aids if necessary for 6min. The Cwfree was measured at a stabilized metabolic rate by indirect calorimetry with the Metamax 3B spiroergometry device. The relation between Sfree and Cwfree was analyzed by the correlation coefficient (r) and coefficient of determination (R2). The Cwfree prediction model was developed from a regression equation, then tested on a second population of 29 patients (mean age 62.1 years [SD 13.4]) with the same inclusion and exclusion criteria. RESULTS: For the 26 participants, the Sfree and Cwfree were highly correlated (r= 0.94 and R2=0.97), which allowed for formulating a regression equation and developing the Cwfree prediction model based on Sfree. The prediction model tests yielded accurate results (mean bias -0.02mL.kg-1.m-1; 95% limits of agreement 0.31 to 0.26mL.kg-1.m-1). The relation between Cwfree estimated by the model and measured by Metamax was high (R2=0.98). CONCLUSION: Cwfree was strongly correlated with Sfree, which allowed for the development of a valid Cwfree prediction model. A practitioner could estimate the energy expenditure of walking for a patient without using an indirect calorimeter. PMID- 29574117 TI - GAPDH as a model non-canonical AU-rich RNA binding protein. AB - Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) plays a key role in glycolysis but is also known for its involvement in a myriad of extra-glycolytic functions. While GAPDH is not the only enzyme with established moonlighting roles, it shows great diversity in terms of its functions, cellular localizations, protein partners, and post-translational modifications. This review focuses on GAPDH's role as a non-canonical RNA binding protein to regulate the stability and translation of cellular mRNAs. Despite the clear involvement of GAPDH in gene expression regulation, how and where GAPDH binds to its RNA targets is still unknown. In addition, the mechanism by which GAPDH switches among its various cellular functions is also unknown. This review will summarize our current understanding of GAPDH-mediated regulation of RNA function. PMID- 29574118 TI - Selection of specific aptamer against enrofloxacin and fabrication of graphene oxide based label-free fluorescent assay. AB - Specific ssDNA aptamers for the antibiotic enrofloxacin (ENR) were isolated from an enriched nucleotide library by SELEX (Systematic Evolution of Ligands by EXponential enrichment) method with high binding affinity. After seven rounds, five aptamers were selected and identified. Apt58 with highest affinity and sensitivity (Kd = 14.19 nM) was employed to develop a label-free fluorescent biosensing approach based on aptamer, graphene oxide (GO) and native fluorescence of ENR for determination of ENR residue in raw milk samples. Under optimized experimental conditions, the linear range was from 5 nM to 250 nM and LOD was calculated to be 3.7 nM, and the recovery rate was between 94.1% and 108.5%. The integration of aptamer and GO in this bioassay provides a promising way for rapid, sensitive and cost-effective detection of ENR in real samples like raw milk. PMID- 29574119 TI - Scrubbing technique for needleless connectors to minimize contamination risk. AB - This study aimed to investigate the appropriate scrubbing technique for needleless connectors to minimize contamination risk. To demonstrate a highly effective scrubbing technique to physically eliminate bacteria, needleless connectors were contaminated with Geobacillus stearothermophilus spores and then scrubbed. The study showed that the highest bacterial elimination rate was achieved by scrubbing an access port in a straight line with an alcohol cotton swab, applying a force that was almost equal to an arterial compression haemostasis to the access port, and repeating this procedure once using a new alcohol cotton swab.

AB - Twiddler's syndrome is the deliberate, inadvertent, or subconscious manipulation of an implantable generator within its subcutaneous pocket that can lead to malposition and fracture of the associated lead. The syndrome is well recognized in patients with pacemakers, implantable cardioverter defibrillators, deep brain stimulators, and more recently in intrathecal drug delivery devices. Here we present an instance of Twiddler's syndrome after sacral neuromodulation. PMID- 29574122 TI - Autologous Rectus Fascia Graft Interposition Repair of Urethrocutaneous Fistulae in Female-to-Male Metoidioplasty Patients. AB - OBJECTIVE: To describe our technique and outcomes using an autologous rectus fascia interposition graft for repair of recurrent urethrocutaneous fistulae (UCF) following metoidioplasty. MATERIALS AND METHODS: A circumferential incision is made to the skin surrounding the UCF and carried to the level of the underlying subcutaneous tissues. The inner fistula skin edges are closed with a running 5-0 monofilament absorbable suture to obliterate the urethral side. The length of the urethral wound is measured and an appropriate sized rectus fascia graft harvested from a small transverse lower abdominal incision that is also used for concomitant percutaneous suprapubic tube placement. Prior to outer skin closure with a running 5-0 monofilament absorbable suture, the fascial graft is spread-fixed between the urethra and skin to avoid overlapping suture lines. A 10 French urethral catheter is removed after 10 days and the suprapubic catheter removed after 2-3 weeks. RESULTS: Three patients have undergone repair of recurrent UCF with this technique since February 2017. All patients had undergone metoidioplasty with a mean time to fistula occurrence of 3.2 months. Mean number of prior UCF repairs was 3.0. With a median follow-up since repair of 7.0 months (range 4-8), no patient has reported UCF recurrence. CONCLUSION: UCF following metoidioplasty is a difficult surgical complication. Fistula closure with interposition of autologous rectus fascia allows for separation of suture lines and encourages healing without extensive reconstruction. PMID- 29574123 TI - Decisional Quality in Patients With Small Renal Masses. AB - OBJECTIVE: To measure decisional quality in patients being counseled on treatment for small renal masses and identify potential areas of improvement. MATERIALS AND METHODS: A total of 73 patients diagnosed with small renal masses at the University of California, Los Angeles Health completed an instrument measuring decisional conflict, patient satisfaction with care, disease-specific knowledge, and patient impression that shared decision-making occurred in the visit after counseling by a specialist. Participant characteristics were compared between those with high and low decisional conflict using chi-square or Student t test (or Wilcoxon rank-sum test). RESULTS: Participants were mostly older (mean age 63.5), white (84%), in a relationship (61%), and unemployed or retired (63%). Mean knowledge score was 59% correct. The mean (standard deviation) decisional conflict score was 16.4 (18.4) indicating low levels of decisional conflict but with a wide range of scores. Comparing participants with high decisional conflict with those with low decisional conflict, there were significant differences in knowledge scores (Wilcoxon P = .0069), patient satisfaction with care (P = .0011), and perceived shared decision-making (P <.0001). CONCLUSION: Patients with small renal masses generally have low levels of decisional conflict and can identify a preferred treatment after a physician visit. However, both groups lack overall knowledge about their disease even after counseling, and thus may be heavily influenced by paternalistic care. Those patients with decisional conflicts are less likely to perceive their care as satisfactory and are less likely to be involved in decision-making. PMID- 29574124 TI - Providing Level-of-Match Information to Perfectly Matched Unrelated Stem Cell Donors: Evaluating Acceptability and Potential Changes in Donor Availability. AB - Patients with blood-related diseases often cannot identify a matched related donor and must seek donors in unrelated donor registries. These registries face the challenge of ensuring that potential donors are available when contacted. Donor attrition is especially problematic when there is only a single perfectly matched potential donor. One way to improve donor availability might be to present perfectly matched donors (high-priority donors [HPDs]) with more precise information about their match status. This project evaluated the impact of providing such information to HPDs at the National Marrow Donor Program (NMDP)/Be The Match. Objectives were to determine the acceptability of the new messaging to both HPDs and the donor contact representatives (DCRs) who delivered the message, consistency of message delivery, and whether the new messaging was associated with improved donor availability. Mixed methods were used to collect telephone interview data from HPDs, matched samples of non-HPDs, and DCRs. Donor availability data came from NMDP records. Key findings were as follows: (1) the HPD message was acceptable to potential donors and did not seem to produce undue pressure, (2) the message was acceptable to DCRs who became more comfortable and consistent in delivering the message over time, but (3) the new messaging did not significantly increase availability. Despite the lack of evidence for increased availability, there may be ethical benefits and little harm to providing well matched donors with more information about their degree of matching. Research should examine stronger match status messages and delivery of new messaging to additional highly-matched donor groups. PMID- 29574125 TI - Higher incidence of metachronous advanced neoplasia in patients with synchronous advanced neoplasia and left-sided colorectal resection for colorectal cancer. AB - BACKGROUND AND AIMS: There is an increased risk of developing metachronous colorectal cancer (CRC) in the remnant colorectum after surgical resection of CRC. We evaluated the incidence of metachronous advanced neoplasia (AN) after surgery for CRC according to resection type and synchronous AN. METHODS: This cohort study included patients who underwent surgical resection for initial CRC at a tertiary cancer center in Japan between September 2002 and December 2012. The cumulative probability of metachronous AN was calculated using the Kaplan Meier method and was evaluated by the log-rank test. RESULTS: Metachronous AN was detected in 145 of 1731 included patients, and the 5-year cumulative probability of metachronous AN was 13.1%. There was no significant difference in the incidence of metachronous AN in the right-sided colorectal resection versus left sided colorectal resection (LCR) groups (log-rank test P = .151), whereas the incidence of metachronous AN was significantly higher in patients with synchronous AN (log-rank test P < .001). In subgroup analysis of patients according to resection type and synchronous AN, the LCR group with synchronous AN showed a significantly higher incidence of metachronous AN than the other groups (log-rank test P < .001). CONCLUSIONS: We found that synchronous AN, but not resection type, was independently associated with the incidence of metachronous AN in patients who underwent surgical resection of CRC. In addition, subjects with synchronous AN after LCR had a potentially increased risk for metachronous AN. Thus, it may be useful to perform risk stratification according to synchronous AN and resection type. PMID- 29574126 TI - Stent placement by EUS or ERCP for primary biliary decompression in pancreatic cancer: a randomized trial (with videos). AB - BACKGROUND AND AIMS: Studies on EUS-guided transmural biliary drainage (EUS-BD) have evaluated its efficacy as a rescue technique after failed ERCP. We performed a single-center, single-blind, randomized trial to compare EUS-BD and ERCP as primary treatment for distal biliary obstruction in pancreatic cancer. METHODS: Patients underwent EUS-BD (n = 33) or ERCP (n = 34). The primary endpoint was the rate of adverse events. Secondary endpoints were technical success, treatment success (defined as decline in serum bilirubin by 50% at a 2-week follow-up), reinterventions, and intraoperative technical outcome, when applicable. Follow-up was until death or a minimum of 6 months. RESULTS: The rates of adverse events were 21.2% (6.1% moderate severity; others mild severity) in the EUS-BD group and 14.7% (5.9% moderate severity; others mild severity) in the ERCP group (risk ratio, .69; 95% confidence interval, .24-1.97; P = .49). There were no procedure related deaths. There was no significant difference in the rates of technical success (90.9% vs 94.1%, P = .67), treatment success (97% vs 91.2%, P = .61), or reinterventions (3.0% vs 2.9%, P = .99) between EUS-BD and ERCP cohorts, respectively. The endoscopic interventions did not impede subsequent pancreaticoduodenectomy that was performed in 5 of 33 patients (15.2%) in the EUS BD and 5 of 34 patients (14.7%) in the ERCP group (P = .99). CONCLUSIONS: Given the similar rates of adverse events and treatment outcomes in this randomized trial, EUS-BD is a practical alternative to ERCP for primary biliary decompression in pancreatic cancer.

PMID- 29574128 TI - Oligonucleotide aptamers against tyrosine kinase receptors: Prospect for anticancer applications. AB - Transmembrane receptor tyrosine kinases (RTKs) play crucial roles in cancer cell proliferation, survival, migration and differentiation. Area of intense research is searching for effective anticancer therapies targeting these receptors and, to date, several monoclonal antibodies and small-molecule tyrosine kinase inhibitors have entered the clinic. However, some of these drugs show limited efficacy and give rise to acquired resistance. Emerging highly selective compounds for anticancer therapy are oligonucleotide aptamers that interact with their targets by recognizing a specific three-dimensional structure. Because of their nucleic acid nature, the rational design of advanced strategies to manipulate aptamers for both diagnostic and therapeutic applications is greatly simplified over antibodies. In this manuscript, we will provide a comprehensive overview of oligonucleotide aptamers as next generation strategies to efficiently target RTKs in human cancers. PMID- 29574129 TI - Activity dependent internalization of the glutamate transporter GLT-1 requires calcium entry through the NCX sodium/calcium exchanger. AB - GLT-1 is the main glutamate transporter in the brain and its trafficking controls its availability at the cell surface, thereby shaping glutamatergic neurotransmission under physiological and pathological conditions. Extracellular glutamate is known to trigger ubiquitin-dependent GLT-1 internalization from the surface of the cell to the intracellular compartment, yet here we show that internalization also requires the participation of calcium ions. Consistent with previous studies, the addition of glutamate (1 mM) to mixed primary cultures (containing neurons and astrocytes) promotes GLT-1 internalization, an effect that was suppressed in the absence of extracellular Ca2+. The pathways of Ca2+ mobilization by astrocytes were analyzed in these mixed cultures using the genetically encoded calcium sensor GCaMP6f. A complex pattern of calcium entry was activated by glutamate, with a dramatic and rapid rise in the intracellular Ca2+ concentration partially driven by glutamate transporters, especially in the initial stages after exposure to glutamate. The Na+/Ca2+ exchanger (NCX) plays a dominant role in this Ca2+ mobilization and its blockade suppresses the glutamate induced internalization of GLT-1, both in astrocytes and in a more straightforward experimental system like HEK293 cells transiently transfected with GLT-1. This regulatory mechanism might be relevant to control the amount of GLT-1 transporter at the cell surface in conditions like ischemia or traumatic brain injury, where extracellular concentrations of glutamate are persistently elevated and they promote rapid Ca2+ mobilization. PMID- 29574130 TI - Gut microbiota analysis of juvenile genetically improved farmed tilapia (Oreochromis niloticus) by dietary supplementation of different resveratrol concentrations. AB - The genetically improved farmed tilapia (GIFT, Oreochromis niloticus) is cultured widely for production of freshwater fish in China, while streptococcosis, likely related to pathogenic infections, occurs frequently in juvenile, mother, and operated GIFT. The gut microbiota plays an important role in nutrient digestibility in animals, and resveratrol (RES) has been used in feed for different freshwater fish species. Therefore, understanding changes in the tilapia gut microbiota across different concentrations of dietary RES supplementation is extremely important. The gut microbiota population in tilapia at 45 d after supplementation with different concentrations (0, 0.025, 0.05, 0.1 g/kg) of dietary RES was assessed by 16S rDNA gene sequencing. A total of 5445 operational taxonomic units were identified from all samples, and 14 phyla and 81 families were identified from all fecal samples. The bacteria of the phylum Firmicutes were significantly enriched in the 0.025 g/kg RES group when compared with the controls. Proteobacteria, Firmicutes and Cyanobacteria were the most dominant three phyla in all samples. With the increasing concentrations, the proportion of beneficial microbial taxa (Acetobacteraceae and Methylobacteriaceae) increased, whereas the proportion of harmful microbial taxa decreased, eg. Streptococcaceae except for 0.1 g/kg RES groups. RES did not affect the richness and diversity in tilapia gut microbiota. These findings provide information on the diversity and differences in GIFT gut microbiota database, and may contribute to developing strategies for management of diseases and long-term sustainability of O. niloticus culture. PMID- 29574131 TI - A tumor-activatable particle with antimetastatic potential in breast cancer via inhibiting the autophagy-dependent disassembly of focal adhesion. AB - In attempts to explore the role of autophagy in breast cancer metastasis, we here report a tumor-activatable particle (named as "D/PSP@CQ/CaP") with the ability of efficient autophagy inhibition. D/PSP@CQ/CaP was prepared by coprecipitating chloroquine phosphate (CQ) with calcium chloride, in the form of chloroquine calcium phosphate coprecipitate (CQ/CaP), onto the surface of a deep-tumor penetrating doxorubicine (DOX)-loading core particle (named as "D/PSP"). CQ/CaP could partly disintegrate and release CQ within tumor microenvironment and totally be dissolved within lysosomes. Paxillin is a key component of focal adhesion which functions to anchor tumors cells within the primary tumor for limiting cancer cells' detachment from the primary tumor. We tested that autophagy inhibition caused by CQ released from CQ/CaP could reduce the degradation of paxillin by 2.9 folds in vitro and 2.5 folds in vivo (vs. Control), respectively. Thus metastasis could be influenced by exploiting autophagy-dependent paxillin degradation. Data analysis together proved that D/PSP@CQ/CaP decreased the cancer metastatic extent by 7.5 folds (vs. Control) on mice model via inhibiting the autophagy-dependent disassembly of focal adhesion. At the same time, the growth rate of tumors treated by D/PSP@CQ/CaP was inhibited by 9.1 folds (vs. Control), which could be attributed to its effective tumor drug delivery. PMID- 29574132 TI - Resveratrol influences platinum pharmacokinetics: A novel mechanism in protection against cisplatin-induced nephrotoxicity. AB - Cisplatin (CP) is a widely used drug in treatment of solid tumors. However, the use of CP was hampered by its serious side effects especially nephrotoxicity. This study aims to investigate the effect of resveratrol (RES) on CP-induced nephrotoxicity, particularly, the effect of RES on CP pharmacokinetics (PKs). Male white albino rats were divided to four group's six rats each. The first group received (1%) tween 80 in normal saline and served as control. The second group received RES (30 mg kg-1) per day for 14 consecutive day's i.p. The third and fourth groups were given a single i.p. injection of CP (6 mg kg-1) with or without pre-treatment of RES (30 mg kg-1per day for 14 consecutive days), respectively. Following administration of CP, plasma, urine and kidney platinum concentration were monitored to study PKs of CP. Five days after the CP injection, rats were killed; blood samples were collected; kidneys were dissected; and biochemical, immunohistochemical, and histological examinations were performed. Our results revealed that CP treatment significantly deteriorated kidney functions with subsequent alteration in redox balance of the kidney. On the other hand, RES successfully ameliorated CP-induced kidney injury and recovered normal kidney tissue redox status. Importantly, while RES pre-treatment did not significantly alter the plasma CP level, it dramatically decreased the urine concentration of CP and lowered its accumulation into the kidneys. Moreover, it increased CP plasma half-life (t1/2) with subsequent decrease in its elimination rate constant, indicating an important role of PKs modulation in RES protection against CP-induced renal damage. Taken together, RES may protect the kidney tissue from the deleterious effects of CP through constringe of CP renal accumulation and enhancement of CP-induced oxidative stress. PMID- 29574133 TI - Kaempferol protects against propacetamol-induced acute liver injury through CYP2E1 inactivation, UGT1A1 activation, and attenuation of oxidative stress, inflammation and apoptosis in mice. AB - Acetaminophen (APAP) overdose can induce acute liver injury (ALI) with significant morbidity and mortality. Propacetamol is an APAP prodrug, which is clinically bioequivalent to APAP. Kaempferol, a dietary flavonoid, has antioxidant, anti-inflammatory, and anti-apoptotic effects. In this study, we investigated the protective effect of kaempferol on propacetamol-induced ALI and its underlying mechanism in mice. Kaempferol pretreatment (125 mg/kg) before propacetamol injection significantly decreased propacetamol-induced serum ALT and AST activities, and DNA fragmentation. Kaempferol administration also reduced propacetamol-induced oxidative stress by inhibiting thiobarbituric acid reactive substances (TBARS) and 3-nitrotyrosine (3-NT) formation partly through downregulation of cytochrome P450 2E1 (CYP2E1) expression, upregulation of UDP glucuronosyltransferase family 1 member A1 (UGT1A1) expression, restoration of the activities of antioxidant enzymes including SOD, GPx and catalase toward normal, recovery of propacetamol-suppressed Nrf2 and GCLC expressions, and maintenance of normal glutathione level. Furthermore, kaempferol markedly attenuated APAP-induced serum TNF-alpha and IL-6 productions, downregulated APAP induced phosphorylations of JNK and ERK, and decreased early hepatic apoptosis via decreasing Bax/Bcl-2 ratio and caspase 3 activation. Furthermore, administration of N-acetylcysteine (NAC) and kaempferol significantly rescued more mice than a low dose of NAC only did when a lethal dose of propacetamol injected and therapized at a delayed time point. These data suggested that kaempferol protects the liver against propacetamol-induced injury through anti oxidative, anti-inflammatory and anti-apoptotic activities. PMID- 29574134 TI - Assessment of N-acetylcysteine as a therapy for phosgene-induced acute lung injury. AB - The toxic industrial chemical (TIC1) phosgene remains an important chemical intermediate in many industrial processes. Inhalation of phosgene can cause an acute lung injury (ALI) which, in severe cases may result in death. There are currently no effective pharmacological therapies or evidence-based treatment guidelines for managing exposed individuals. N-acetylcysteine (NAC) is a commercially available drug licensed in the UK and elsewhere for the treatment of paracetamol (acetaminophen) overdose. It has a number of mechanisms of action which may provide therapeutic benefit for the treatment of phosgene-induced ALI. It has previously been shown to provide therapeutic efficacy against the lung damaging effects of sulfur mustard vapour exposure, when given by the inhaled route, in the pig (Jugg et al., 2013). Our research objective was to determine whether inhaled NAC might also be therapeutic for other chemicals, in this case, phosgene. This study has demonstrated that multiple nebulised doses, administered from 30 min after exposure of terminally anaesthetised pigs to phosgene, is not an effective therapy when administered at the times and doses employed in this study. There remains no pharmacological treatment for phosgene-induced lung injury. PMID- 29574135 TI - Cryopreservation and in vitro culture of white-tailed deer ovarian tissue. AB - The aims of this study were to evaluate (1) the survivability of white-tailed deer ovarian tissue after cryopreservation by slow-freezing (SF) and vitrification (VIT) techniques and in vitro culture (IVC) for up to 7 days, and (2) the effects of cryopreservation techniques on protein expression of proliferative and apoptotic markers of ovarian tissue pre- and post-in vitro culture. Ovaries (n = 14) of seven white-tailed deer fawns (<1.5 years old) were used. Ovarian cortexes were cut into fragments (2 * 2 * 0.5 mm) and split into nine treatment groups: (1) fresh noncultured control, (2) fresh-IVC 1 day, (3) fresh-IVC 7 days, (4) SF noncultured, (5) SF-IVC 1 day, (6) SF-IVC 7 days, (7) VIT noncultured, (8) VIT-IVC 1 day, and (9) VIT-IVC 7 days. Preantral follicle morphology, class distribution, and density; stromal cell density; EGFR, Ki-67, Bax, and Bcl-2 protein expression; and DNA fragmentation were assessed. Results showed that: (i) white-tailed deer fresh ovarian tissue can be cultured for up to 7 days, preserving the tissue integrity and 50% of morphologically normal preantral follicles; (ii) cryopreservation of white-tailed deer ovarian tissue by either slow-freezing or vitrification does not disrupt markers of proliferation and apoptosis after thawing; (iii) ovarian fragments cryopreserved by the vitrification method had greater follicle viability during in vitro culture than the slow-freezing method; and (iv) fragments cryopreserved by slow-freezing suffered apoptosis earlier than those preserved by vitrification. The findings herein reported advance knowledge towards development of adequate cryopreservation protocols for long-term banking programs for Cervidae species. PMID- 29574136 TI - Reply.

AB - Wuho known as WDR4 encodes a highly conserved WD40-repeat protein, which has known homologues of WDR4 in human and mouse. Wuho-FEN1 interaction may have a critical role in the growth and development, and in the maintenance of genome stability. However, how Wuho gene deletion contributes to cell growth inhibition and apoptosis is still unknown. We utilized CAGGCre-ER transgenic mice have a tamoxifen-inducible cre-mediated recombination cassette to prepare primary mouse embryonic fibroblasts (MEFs) with Wuho deficiency. We have demonstrated that Wuho deficiency would induces gammaH2AX protein level elevation, heterochromatin relaxation and DNA damage down-stream sequences, including p53 activation, caspase-mediated apoptotic pathway, and p21-mediated G2/M cell cycle arrest.

AB - BACKGROUND: Loss-of-function mutations in SCN5A are associated in ~20% of Brugada syndrome (BrS) patients. Copy number variations (CNVs) have been shown to be associated with several inherited arrhythmia syndromes. OBJECTIVE: The purpose of this study was to investigate SCN5A CNVs among BrS probands. METHODS: The study cohort consisted of 151 BrS probands who were symptomatic or had a family history of BrS, sudden death, syncope, or arrhythmic diseases. We performed sequence analysis of SCN5A by the Sanger method. For detecting CNVs in SCN5A, we performed multiplex ligation-dependent probe amplification analysis of the 151 BrS probands. RESULTS: We identified pathogenic SCN5A mutations in 20 probands by the Sanger method. In 140 probands in whom multiplex ligation-dependent probe amplification was successfully performed, 4 probands were found to present different CNVs (deletion in 3 and duplication in 1). Three of them had fatal arrhythmia events; the remaining 1 was asymptomatic but had a family history. Mean age at diagnosis was 23 +/- 14 years. All of the baseline 12-lead electrocardiograms showed PQ-interval prolongation. The characteristics of these 4 probands with CNVs were similar to those of the probands with mutations leading to premature truncation of the protein or missense mutations causing peak INa reduction >90%. CONCLUSION: We identified SCN5A CNVs in 2.9% of BrS probands who were symptomatic or had a family history. PMID- 29574142 TI - Exploring the interactions of EGFR with phosphorylated Mig6 by molecular dynamics simulations and MM-PBSA calculations. AB - Mig6, a negative regulator, directly binds to epidermal growth factor receptor (EGFR), including Mig6-segment1 and Mig6-segment2. Mig6 requires phosphorylation of Y394 on Mig6-segment2 in order to inhibit EGFR. Two phosphorylation pathways for Y394 have been previously reported and the first way may phosphorylate Y394 primed by Y395 phosphorylation. Besides, the binding mechanism of phosphorylated Mig6-segment2 with EGFR has not been elucidated clearly. Focused on EGFR complex with phosphorylated Mig6-segment2, molecular dynamics (MD) simulations were performed to explore the interactions of Mig6-segment2 with EGFR. Our results indicate a probable phosphorylation pathway on Y394 and some key residues of EGFR play important roles in binding to phosphorylated Mig6-segment2. In addition, a special L-shaped structure was found to be possibly associated with irreversible inhibition of EGFR by Mig6. Our work can give meaningful information to better understand the phosphorylation pathways for Y394 and the interactions of EGFR binding to phosphorylated Mig6-segment2.

AB - The Mediterranean Diet Foundation, in collaboration with the International Menarini Foundation, organized the "International Conference on Mediterranean Diet and Health: A Lifelong Approach." The Conference was held in Ostuni (Puglia, Italy) from March 30 to April 1, 2017. The event received the endorsement of the American Federation for Aging Research, the Research Consortium "Luigi Amaducci," the European Nutrition for Health Alliance, the European Union Geriatric Medicine Society, the Clinical Section of the International Association of Gerontology and Geriatrics-European Region, the National Research Council Research Project on Aging, the Italian Society of Gerontology and Geriatrics, and the Italian Society of Clinical Nutrition and Metabolism. During the conference, results were presented from major studies on dietary interventions aiming to assess the efficacy of the Mediterranean diet in the prevention of chronic diseases and the potential underlying mechanisms. Twenty-six international speakers, in seven different sessions, discussed the biological basis, clinical impact, health policy, and behavioral implications of the Mediterranean diet, and its use in potential interventions for health promotion.

AB - We have tested the in vitro susceptibility to the neuraminidase (NA) inhibitors of 96 highly pathogenic clade 2.1 A(H5N1) viruses from Indonesia, isolated between 2008 and 2011. HPAI virus samples obtained through the Influenza Virus Monitoring (IVM) surveillance program in Indonesia were tested for susceptibility to oseltamivir and zanamivir. The NAs of four viruses were identified as extreme outliers to oseltamivir, based on statistical analysis by box plots, with IC50 values ranging from 46 to 62 nM. The NAs of two of these viruses from Sumatra and Aceh, had an N294S substitution, while one virus from Sulawesi had an S246N NA substitution. The NAs of all four viruses showed a specific loss of slow binding to oseltamivir in an IC50 kinetics assay. As observed in our previous surveillance, there was only a minimal effect on the sensitivity to zanamivir or peramivir for these mutants or any of the other isolates tested. The continued circulation of subtype H5N1 viruses in avian species poses an on-going zoonotic threat. The fact that we continue to identify avian isolates with naturally occurring mutations conferring reduced oseltamivir susceptibility remains a concern, given oseltamivir will be a key antiviral in the event of a new pandemic emerging. PMID- 29574146 TI - A mathematical analysis of Prx2-STAT3 disulfide exchange rate constants for a bimolecular reaction mechanism. AB - Appreciation of peroxiredoxins as the major regulators of H2O2 concentrations in human cells has led to a new understanding of redox signaling. In addition to their status as the primary reducers of H2O2 to water, the oxidized peroxiredoxin byproduct of this reaction has recently been shown capable of participation in H2O2-mediated signaling pathways through disulfide exchange reactions with the transcription factor STAT3. The dynamics of peroxidase-transcription factor disulfide exchange reactions have not yet been considered in detail with respect to how these reactions fit into the larger network of competing reactions in human cells. In this study, we used a kinetic model of oxidation and reduction reactions related to H2O2 metabolism in the cytosol of human cells to study the dynamics of peroxiredoxin-2 mediated oxidation of the redox-regulated transcription factor STAT3. In combination with previously reported experimental data, the model was used to estimate the rate coefficient of a biomolecular reaction between Prx2 and STAT3 for two sets of assumptions that constitute lower and upper bound cases. Using these estimates, we calculated the relative rates of the reaction of oxidized peroxiredoxin-2 and STAT3 and other competing reactions in the cytosol. These calculations revealed that peroxiredoxin-2-mediated oxidation of STAT3 likely occurs at a much slower rate than competing reactions in the cytosol. This analysis suggests the existence of more complex mechanisms, potentially involving currently unknown protein-protein recognition partners, which facilitate disulfide exchange reactions between peroxiredoxin-2 and STAT3. PMID- 29574147 TI - Revisiting available knowledge on teleostean thyroid hormone receptors. AB - Teleosts are the most numerous class of living vertebrates. They exhibit great diversity in terms of morphology, developmental strategies, ecology and adaptation. In spite of this diversity, teleosts conserve similarities at molecular, cellular and endocrine levels. In the context of thyroidal systems, and as in the rest of vertebrates, thyroid hormones in fish regulate development, growth and metabolism by actively entering the nucleus and interacting with thyroid hormone receptors, the final sensors of this endocrine signal, to regulate gene expression. In general terms, vertebrates express the functional thyroid hormone receptors alpha and beta, encoded by two distinct genes (thra and thrb, respectively). However, different species of teleosts express thyroid hormone receptor isoforms with particular structural characteristics that confer singular functional traits to these receptors. For example, teleosts contain two thra genes and in some species also two thrb; some of the expressed isoforms can bind alternative ligands. Also, some identified isoforms contain deletions or large insertions that have not been described in other vertebrates and that have not yet been functionally characterized. As in amphibians, the regulation of some of these teleost isoforms coincides with the climax of metamorphosis and/or life transitions during development and growth. In this review, we aimed to gain further insights into thyroid signaling from a comparative perspective by proposing a systematic nomenclature for teleost thyroid hormone receptor isoforms and summarize their particular functional features when the information was available. PMID- 29574148 TI - alpha-Melanocyte-stimulating hormone promotes bone resorption resulting from increased osteoblastic and osteoclastic activities in goldfish. AB - We examined the effects of alpha-melanocyte-stimulating hormone (alpha-MSH) on bone metabolism using regenerating goldfish scales. Normally developed scales on the bodies of goldfish were removed to allow the regeneration of scales under anesthesia. Thereafter, the influence of alpha-MSH on the regeneration of goldfish scales was investigated in vivo. In brief, alpha-MSH was injected at a low dose (0.1 MUg/g body weight) or a high dose (1 MUg/g body weight) into goldfish every other day. Ten days after removing the scales, we collected regenerating scales and analyzed osteoblastic and osteoclastic activities as respective marker enzyme (alkaline phosphatase for osteoblasts, tartrate resistant acid phosphatase for osteoclasts) activity in the regenerating scales as well as plasma calcium levels. At both doses, osteoblastic and osteoclastic activities in the regenerating scales increased significantly. Plasma calcium concentrations in the alpha-MSH-treated group (high doses) were significantly higher than those in the control group. Next, in vitro experiments were performed to confirm the results of in vivo experiments. In the cultured regenerating scales, osteoblastic and osteoclastic activities significantly increased with alpha-MSH (10-7 and 10-6 M) treatment. In addition, real-time PCR analysis indicated that osteoclastogenesis in alpha-MSH-treated scales was induced by the receptor activator of the NF-kappaB/receptor activator of the NF-kappaB ligand/osteoprotegerin pathway. Furthermore, we found that alpha-MSH receptors (melanocortin receptors 4 and 5) were detected in the regenerating scales. Thus, in teleosts, we are the first to demonstrate that alpha-MSH functions in bone metabolism and promotes bone resorption via melatonin receptors 4 and/or 5. PMID- 29574149 TI - Left-right pigmentation pattern of Japanese flounder corresponds to expression levels of melanocortin receptors (MC1R and MC5R), but not to agouti signaling protein 1 (ASIP1) expression. AB - Body coloration in flatfish is one of the most distinctive asymmetries in the animal kingdom, although the fundamental molecular mechanism of the pigmentation is unclear. In the dorso-ventral coloration (countershading) of other teleost fishes, ventral-specific expression of agouti signaling protein 1 (ASIP1), an endogenous antagonist of melanocortin 1 receptor (MC1R), has been reported to play a pivotal role. Contribution of ASIP1 is also suggested in the asymmetrical pigmentation of flatfish. In order to confirm the contribution of ASIP1 and further examine receptor function in the body coloration of Japanese flounder, expression levels of asip1, mc1r, melanocortin 5 receptor (mc5r), and melanin concentrating hormone receptor 2 (mchr2) were measured in the normally pigmented area of the left side, the normally non-pigmented area of the right side, and the abnormally pigmented (exhibiting hypermelanosis) area of the right side. Measurement was also carried out under conditions of hypermelanosis stimulated by cortisol and during the transition from non-pigmentation to pigmentation in areas of hypermelanosis. Contrary to our expectations, no difference was detected in asip1 expression between pigmented and non-pigmented areas. There was also no difference between normal and hormonally stimulated pigmented conditions in areas of hypermelanosis or during the transition process. Instead, the expression levels of mc1r, mc5r, and mchr2 were consistently higher in pigmented areas, and were especially increased under hormonally stimulated conditions. In addition, expressions of these receptor genes increased prior to pigmentation in areas of future hypermelanosis. Our results suggest that MC1Rand MC5R, but not necessarily ASIP1, contribute to pigmentation and hypermelanosis in Japanese flounder. We propose a yet unknown molecular mechanism for asymmetrical pigmentation in flatfish that is distinct from that of countershading in other vertebrates. PMID- 29574150 TI - Role of natriuretic peptide receptor 2-mediated signaling in meiotic arrest of zebrafish oocytes and its estrogen regulation through G protein-coupled estrogen receptor (Gper). AB - Natriuretic peptide type C (NPPC) and its receptor, natriuretic peptide receptor 2 (NPR2), have essential roles in maintaining meiotic arrest of oocytes in several mammalian species. However, it is not known if a similar mechanism exists in non-mammalian vertebrates. Using zebrafish as a model, we show that Nppc is expressed in ovarian follicle cells, whereas Npr2 is mainly detected in oocytes. Treatment of intact and defolliculated oocytes with 100 nM NPPC for 6 h caused a large increase in cGMP concentrations, and a significant decrease in oocyte maturation (OM), an effect that was mimicked by treatment with 8-Br-cGMP. Treatment with E2 and G-1, the specific GPER agonist, also increased cGMP levels. Cyclic AMP levels were also increased by treatments with 8-Br-cGMP, E2 and G1. The estrogen upregulation of cAMP levels was blocked by co-treatment with AG1478, an inhibitor of EGFR activation. Gene expression of npr2, but not nppc, was significantly upregulated in intact oocytes by 6 h treatments with 20 nM E2 and G 1. Both cilostamide, a phosphodiesterase 3 (PDE3) inhibitor, and rolipram, a PDE4 inhibitor, significantly decreased OM of intact and defolliculated oocytes, and enhanced the inhibitory effects of E2 and G-1 on OM. These findings indicate the presence of a Nppc/Npr2/cGMP pathway maintaining meiotic arrest in zebrafish oocytes that is upregulated by estrogen activation of Gper. Collectively, the results suggest that Nppc through Npr2 cooperates with E2 through Gper in upregulation of cGMP levels to inhibit phosphodiesterase activity resulting in maintenance of oocyte meiotic arrest in zebrafish. PMID- 29574151 TI - Oviduct morphology and estrogen receptors ERalpha and ERbeta expression in captive Chinchilla lanigera (Hystricomorpha: Chinchillidae). AB - Chinchilla lanigera is a hystricomorph rodent from South America whose reproductive biology presents particular characteristics that distinguishes it from other Rodentia species, such as low reproductive rate, seasonal breeding pattern, and long estrous cycle. Nevertheless, reproductive features in female chinchillas are still poorly investigated, with a scarce knowledge concerning the estrous cycle and the histology of reproductive organs. In this study, we investigate the morphology, histomorphometry, secretory activity, and immunolocalization of estrogen receptors ERalpha and ERbeta in oviducts of nulliparous chinchillas, euthanized at fall season in Brazil. Follicular phase of estrous cycle of all studied animals was characterized by ovary and uterine morphology inspection, as well as vaginal cytology. Similar to other mammals, the oviduct wall of infundibulum, ampulla and isthmus was composed of mucosa, muscle, and serosa layers. Morphometric data of oviduct layers were used for identifying each oviduct segment. In the follicular phase, the oviduct was characterized by intense secretory activity, mainly in the ampulla, and expression of ERalpha and ERbeta throughout the oviduct epithelium. Both ERalpha and ERbeta were also detected in the connective tissue and smooth muscle cells. Our findings point out to the important role of estrogen in this female organ. Similar wide distribution of both ER proteins has been described for human Fallopian tube. Taken together, our data add to the understanding of the reproductive biology of female chinchillas, and may assist in the intensive breeding of this species and any eventual endeavor for conservation of chinchillas in the wild.

PMID- 29574153 TI - Inhibition of KLHL21 prevents cholangiocarcinoma progression through regulating cell proliferation and motility, arresting cell cycle and reducing Erk activation. AB - Kelch-like family member 21 (KLHL21) is involved in cell mitosis and motility. Nevertheless, the clinical significance and biological function of KLHL21 in cholangiocarcinoma (CCA) are elusive. This is the first study to describe a pivotal role for KLHL21 in the progression of CCA. The expression of KLHL21 was elevated in CCA tissues compared with paired normal bile duct tissues. In addition, immunohistochemical and statistical analyses demonstrated that the expression of KLHL21 correlated inversely with tumor histological grade (p < 0.05) and the overall survival of patients (p < 0.01). In CCA cells, we found that the inhibition of KLHL21 significantly reduced proliferation, migration and invasion. Further results indicated that inhibition of KLHL21 triggered G0/G1 cell cycle arrest, leading to the increased expression of P21 and P27 and decreased expression of Cyclin E1, which eventually resulted in proliferation suppression in CCA cells. Furthermore, KLHL21 knockdown alleviated the activation of the Erk signaling pathway via decreasing the expression of phospho-Erk1/2. Our data demonstrated that KLHL21 plays an essential role in the tumorigenesis and progression of CCA, implying that it might serve as a potential therapeutic target for CCA treatment. PMID- 29574154 TI - PDLIM5 identified by label-free quantitative proteomics as a potential novel biomarker of papillary thyroid carcinoma. AB - In order to better understand the mechanisms underlying the development of papillary thyroid carcinoma (PTC), and to identify new potential biomarkers, high resolution label-free mass spectrometry was performed on PTC tissues and adjacent normal thyroid tissues from six patients. In this process, 2788 proteins were identified, out of which 49 proteins presented significant differences between PTC tissues and adjacent normal thyroid tissues. Gene ontology revealed that the majority of these proteins are involved in the catalytic activity and binding. We selected three proteins with differential expressions: PDZ and LIM domain 5 (PDLIM5), PDLIM1 and ALDH1A1; Protein expressions were further verified by RT-PCR and western blot. Among these, expression of PDLIM5 and PDLIM1 was up-regulated, while that of ALDH1A1 was down-regulated in PTC tissues. Next, we confirmed their expression through quantitative dot blot (QDB) technique. We found that knockdown of PDLIM5 expression in the B-CPAP cell line could inhibit the migration, invasion and proliferation of PTC cells. In addition, PDLIM5 knockdown reduced Ras and Phospho-ERK1/2 expression. Thus, we suggested that PDLIM5 promotes PTC via activation of the Ras-ERK pathway. Our research provides new molecular insight into the function of PDLIM5, which may assist in studying the mechanism of PTC. In addition, PDLIM5 could be further explored as a potential candidate for PTC treatment. PMID- 29574155 TI - Autophagy is involved in the protective effect of endophilin A2 on H2O2-induced apoptosis in H9C2 cardiomyocytes. AB - Apoptosis plays a critical role in normal embryonic development and tissue homeostasis regulation. EndophilinA2 (EndoA2) is widely reported to regulate endocytosis. Additionally, EndoA2 has been demonstrated to be involved in tumor metastasis, neuroregulation and vascular function. In this study, we used siRNA and Ad-EndoA2 transfection strategy to investigate whether EndoA2 provides a protective effect against apoptosis induced by H2O2 in H9C2 cardiomyocytes and the underlying mechanisms. We found that EndoA2 siRNA knockdown promoted H2O2 induced apoptosis in H9C2 cardiomyocytes, evidenced by decreased cell number, increased apoptotic cells, and activation of caspase-3. In contrast, EndoA2 overexpression showed the opposite effects and inhibited H2O2-induced apoptosis in H9C2 cardiomyocytes. Further studies revealed that EndoA2 overexpression strengthened autophagy, evidenced by the increased LC3 II/I ratio and P62 degradation, whereas EndoA2 siRNA knockdown produced the opposite effects. Furthermore, we revealed that there was an interaction between Bif-1 and Beclin 1. Upon H2O2 treatment, the association of Bif-1 and Beclin-1 remarkably increased. EndoA2 overexpression further promoted the binding of Bif-1 with Beclin-1, whereas EndoA2 siRNA knockdown reduced this association. These data strongly suggested that EndoA2 inhibited H2O2-induced apoptosis in H9C2 cardiomyocytes, possibly by promoting Bif-1 to form a complex with Beclin-1 and strengthening autophagy. This study provides a novel target for heart diseases. PMID- 29574156 TI - Serum extracellular vesicles promote proliferation of H9C2 cardiomyocytes by increasing miR-17-3p. AB - Emerging evidence showed that cardiac proliferation played a significant role in the cardiac rehabilitation and repair. Extracellular vesicles (EVs) are known to regulate multiple cell functions, whereas the role of EVs in cardiac proliferation still remains unclear. In this study, we found that serum EVs promoted cell proliferation in rat heart myoblastic H9C2 cells with significantly increased expression level of miR-17-3p. Inhibition of miR-17-3p could decrease H9C2 cells proliferation induced by serum EVs. Additionally, we found that TIMP3 was a target of miR-17-3p in H9C2 cells proliferation and the expression of TIMP3 was downregulated by serum EVs. Meanwhile, inhibition of TIMP3 increased cardiac proliferation. In conclusion, results of our study indicated that serum EVs could promote the proliferation of H9C2 cells via regulating miR-17-3p/TIMP3, which may be a potential therapeutic target for treatment of cardiac injury. PMID- 29574157 TI - Interleukin-23 promotes the migration and invasion of gastric cancer cells by inducing epithelial-to-mesenchymal transition via the STAT3 pathway. AB - Chronic inflammation is associated with all stages of cancer development. Moreover, a proinflammatory microenvironment resulted from chronic inflammation is considered to be an essential component of cancer. Interleukin-23 (IL-23) is a general proinflammatory factor; and is involved in tumor-associated inflammation in gastric cancer (GC). However, the direct effect of IL-23 on GC cells has been rarely reported. The aim of the study was to clarify the direct role of IL-23 in regulating GC progression, and to identify the underlying mechanism. In this study, Positive expression of IL-23R was observed in GC tissues and cell lines by using immunohistochemistry or immunofluorescence. In western blots, the expression of IL-23R was higher in GC tissues compared with adjacent normal tissues. Furthermore, IL-23R positive GC tissues were closely related with larger tumor size and worse T stage and clinical stage. By performing in vitro experiments, we found that IL-23 binding to its receptor promoted the migration and invasion of BGC-823 cells in vitro. Moreover, IL-23 induced the activation of STAT3 and epithelial-to-mesenchymal transition (EMT) in BGC-823 cells. Knocking down STAT3 in BGC-823 cells attenuated the effect of IL-23 on EMT and cell migration and invasion. Taken together, our study has firstly demonstrated the positive expression of IL-23R in human GC tissues and cell lines. IL-23 binding to its receptor promotes the migration and invasion of GC cells by inducing EMT through the STAT3 signaling pathway. This work provides a new mechanism for the oncogenic role of IL-23 on GC progression. PMID- 29574158 TI - CsTFL1b may regulate the flowering time and inflorescence architecture in cucumber (Cucumis sativus L.). AB - Cucumber is an important vegetable with indeterminate growth habit which is beneficial to its yield. In this study, we cloned the TFL1 homolog CsTFL1b in cucumber. CsTFL1b shares highly sequence similarity to TFL1 from Arabidopsis and has conservative histidine amino acid residue which is necessary for TFL1 function. However, phylogenetic analysis suggested that cucurbits TFL1s (CsTFL1b of cucumber and CmTFL1 of melon) formed a subclade which is far from the AtTFL1 in Arabidopsis or CEN in Antirrhinum. CsTFL1b was highest expressed in male flower but barely expressed in SAM which was different from TFL1 in Arabidopsis with highly transcription accumulation in SAM and CsTFL1b was located in nucleus and cytoplasm. Upon ectopic expression of CsTFL1b in Arabidopsis, the flowering time of transgenic plants was significantly delayed in both wild type and tfl1-11 mutant background but the terminal flower phenotype of tfl1-11 mutant was partially rescued. These results may underlie the discrepant function of CsTFL1b in cucumber from that in Arabidopsis. PMID- 29574159 TI - miR-126-5p targets Malate Dehydrogenase 1 in non-small cell lung carcinomas. AB - Malate Dehydrogenase (MDH) 1 has recently been shown to be highly expressed and display prognostic value in non-small cell lung carcinomas (NSCLCs). However, it is not known how MDH1 expression is regulated and there is no current molecular or chemical strategy that specifically targets MDH1. This may be due to structural and enzymatic similarities with its isoenzyme, malate dehydrogenase 2 (MDH2). However, MDH1 and MDH2 are encoded by distinct genes and this opens up the possibility for modulation at the expression level. Here, we screened in silico for microRNAs (miRs) that selectively targets the 3'UTR region of MDH1. These analyses revealed that mir-126-5p has three binding sites in the 3'UTR region of MDH1. Additionally, we show that expression of miR-126-5p suppresses the enzymatic activity of MDH1, mitochondrial respiration and caused cell death in NSCLC cell lines. PMID- 29574160 TI - Reactive oxygen species participate in liver function recovery during compensatory growth in zebrafish (Danio rerio). AB - Compensatory growth (CG) is defined as a phase of accelerated growth when the disadvantageous environment is improved, accompanied by metabolic adjustment. Here, we report that hepatic oxidative phosphorylation (OXPHOS) activity was enhanced during compensatory growth in zebrafish. Mitochondrial metabolism enabled the generation of reactive oxygen species (ROS), which activated the nrf2 (nuclear factor-erythroid 2-related factor 2) signaling pathway, as well as the mTOR signaling pathway. Tempol (a superoxide dismutase mimetic) treatment blocked ROS signaling in the liver as well as CG in zebrafish. These results demonstrated that mitochondrial ROS signaling are essential for the occurrence of compensatory growth in zebrafish. PMID- 29574162 TI - Surgical treatment in bone metastases in the appendicular skeleton. AB - INTRODUCTION: Metastatic bone disease is the most common neoplastic process that affects the skeletal system. Eighty percent of bone metastases come from carcinomas of the breast, lung, kidney, thyroid and prostate. The Katagiri scale enables an estimation of the survival of patients based on the presence or absence of visceral metastases, multiple bone metastases and functional status according to the ECOG scale. MATERIAL AND METHODS: A retrospective, descriptive and observational study conducted between March 1, 2013 and June 30, 2015. Thirty two patients were studied with a diagnosis of metastatic bone disease and who had undergone some type of orthopaedic surgical treatment for pathological fracture or impending fracture. RESULTS: 28 cases (87.5%) presented pathological fracture and 4 cases (12.5%) impending fracture according to the Mirels score. Fifteen cases (46.875%) were treated by placing a central medullary nail + spacer in the long bone diaphysis, 15 cases (46.875%) with modular arthroplasties and 2 patients (6.25%) with forequarter amputation. Eleven patients (34.375%) died during the course of this study, all with a Katagiri greater than or equal to 4. DISCUSSION: The presence of a fracture in previously damaged territory is a catastrophic complication for most cancer patients. A clear understanding of the life expectancy of patients with bone metastases is of great help to prevent errors and failures in treatment. PMID- 29574161 TI - Comparison of functional results of two fixation systems using single-row suturing of rotator cuff. AB - INTRODUCTION: Arthroscopic repair of rotator cuff disorders is a technically demanding but successful procedure. Many anchor and suture alternatives are now available. The choice of the implant by the surgeon is less important than the configuration of the suture used to fix the tendon, however it is necessary to know if there are differences in the results, using each one of them. The aim of the study is to evaluate if there are differences between the knotted and non knotted implant in terms of functional and satisfaction results. MATERIAL AND METHODS: A retrospective study was carried out on 83 patients operated between 2010 and 2014 in our center using 2anchoring systems with and without knotting (39 versus 44 patients respectively), with single row in complete rupture of the rotator cuff. RESULTS: At the end of the follow-up, an average score was obtained on the Constant scale of 74.6 points. 98% of the patients considered the result of the surgery satisfactory. Statistically, there were no significant differences between the 2groups in terms of functionality, satisfaction or reincorporation to activities. DISCUSSION AND CONCLUSIONS: The functional results of the single-row cuff suture are satisfactory, although biomechanical studies show advantages in favor of sutures that reproduce a transoseo system. It our series of patients the presence of knotting does not show per se a significant functional difference being both superimposable techniques in absolute values of functionality and patient satisfaction. PMID- 29574163 TI - Tibial tunnel widening associated with anterior cruciate ligament reconstruction using autogenous hamstrings: A comparison between antero-medial portal and transtibial techniques. AB - OBJECTIVE: Evaluate the enlargement effect of the tibial tunnel emergence of 2 different of anterior cruciate ligament reconstruction techniques: antero-medial portal (AMP) vs. transtibial (TT) technique. METHODS: A prospective, randomized controlled study was performed in 36 consecutive patients who underwent anterior cruciate ligament reconstruction with autologous hamstring tendon grafts employing the AMP and conventional TT techniques. Lateral and antero-posterior radiographs were obtained for each patient at 6 weeks and 12 months postoperatively. The sclerotic margins of the tibial tunnels were measured at the widest dimension of the tunnel as well as the diameter of the tibial emergence and were compared with the initially drilled tunnel size after correction for radiographic magnification. Statistical analysis was performed to compare the 2 groups by use of the independent-samples t test, with significance set at .05. RESULTS: The mean percentage increase in the diameter of tibial tunnel emergence at 6 weeks after surgery was 8.1%+/-2.9 for the PAM technique and 21.20%+/-11.87 for the TT technique on the anteroposterior x-ray view. However, the mean percentage increase in the diameter of the tibial tunnel emergence on the lateral view was 7.1%+/-4.72 for the medial portal technique and 17.64%+/-11.48 for the transtibial technique. This difference was statistically significant on both anteroposterior and lateral views. CONCLUSIONS: The diameter of the tibial tunnel emergence for hamstring autologous anterior cruciate ligament reconstructions was significantly lower for the medial portal technique when compared with the conventional TT technique. PMID- 29574164 TI - Phylodynamic analysis and molecular diversity of the avian infectious bronchitis virus of chickens in Brazil. AB - Avian infectious bronchitis virus (IBV) is the etiological agent of a highly contagious disease, which results in severe economic losses to the poultry industry. The spike protein (S1 subunit) is responsible for the molecular diversity of the virus and many sero/genotypes are described around the world. Recently a new standardized classification of the IBV molecular diversity was conducted, based on phylogenetic analysis of the S1 gene sequences sampled worldwide. Brazil is one of the biggest poultry producers in the world and the present study aimed to review the molecular diversity and reconstruct the evolutionary history of IBV in the country. All IBV S1 gene sequences, with local and year of collection information available on GenBank, were retrieved. Phylogenetic analyses were carried out based on a maximum likelihood method for the classification of genotypes occurring in Brazil, according to the new classification. Bayesian phylogenetic analyses were performed with the Brazilian clade and related international sequences to determine the evolutionary history of IBV in Brazil. A total of 143 Brazilian sequences were classified as GI-11 and 46 as GI-1 (Mass). Within the GI-11 clade, we have identified a potential recombinant strain circulating in Brazil. Phylodynamic analysis demonstrated that IBV GI-11 lineage was introduced in Brazil in the 1950s (1951, 1917-1975 95% HPD) and population dynamics was mostly constant throughout the time. Despite the national vaccination protocols, our results show the widespread dissemination and maintenance of the IBV GI-11 lineage in Brazil and highlight the importance of continuous surveillance to evaluate the impact of currently used vaccine strains on the observed viral diversity of the country. PMID- 29574165 TI - Acupuncture for the Treatment of Paraneoplastic Night Sweats. AB - This case report describes acupuncture treatment to manage paraneoplastic night sweating secondary to pancreatic cancer. A 56-year-old gentleman with a 2-month history of night sweating responded well over a 10-week course of acupuncture treatment. Acupuncture was selected for symptom management after no success was achieved with pharmacological and conventional managements. The severity of night sweating had reduced from 9/10 to 1/10 on visual analog scale at the end of treatment. This case report suggests that acupuncture has a favorable effect on paraneoplastic night sweating in patients with advanced pancreatic cancer and recommends further research. PMID- 29574166 TI - Stem cells from apical papilla promote differentiation of human pluripotent stem cells towards retinal cells. AB - Recently, we have found that human stem cells from apical papilla (SCAP) show a stromal cell-derived inducing activity (SDIA). To examine SDIA competence for retinal cells differentiation, we co-cultured SCAP with human pluripotent stem cells (hPSCs). In comparison with Matrigel-cultured hPSCs, SCAP significantly induces hPSCs to differentiate into rostral neural cells as demonstrated by upregulation of OTX2 and PAX6 and down-regulation of EN1, HOXB4 and HOXC8. Furthermore, the differentiated cells on SCAP significantly expressed eye-field markers, RAX, PAX6, LHX2 and SIX3 and showed five folds pigmented colonies. The generated hPSC-retinal pigmented epithelium (RPE) was hexagonal and highly expressed related markers, ZO-1, RPE65, BEST, CRALBP and MITF. They were able to phagocytose latex beads. Moreover, the assessment of the isolated neural tube like structures on SCAP showed the expression of retinal progenitor cells (RPCs) SIX3, RAX, and PAX6. SCAP highly expressed DKK3 and SFRP2, Wnt inhibitor factors and their target genes, Cyclin D1 and c-Myc were down-regulated significantly on SCAP. These results showed SCAP promoted the differentiation of hPSCs into retinal cells (RPE and RPCs) possibly through inhibition of Wnt signaling pathway. This simple and efficient approach provides human RPE generation for developing therapies for diseases such as age-related macular degeneration. PMID- 29574167 TI - People with low back pain perceive needs for non-biomedical services in workplace, financial, social and household domains: a systematic review. AB - QUESTION: What needs of non-biomedical services are perceived by people with low back pain? DESIGN: Systematic review of qualitative and quantitative studies examining perceived needs of non-biomedical services for low back pain, identified through searching of MEDLINE, EMBASE, CINAHL and PsycINFO (1990 to 2016). PARTICIPANTS: Adults with low back pain of any duration. DATA EXTRACTION AND ANALYSIS: Descriptive data regarding study design and methodology were extracted. The preferences, expectations and satisfaction with non-biomedical services reported by people with low back pain were identified and categorised within areas of perceived need. RESULTS: Twenty studies (19 qualitative and one quantitative) involving 522 unique participants (total pool of 590) were included in this systematic review. Four areas emerged. Workplace: people with low back pain experience pressure to return to work despite difficulties with the demands of their occupation. They want their employers to be informed about low back pain and they desire workplace accommodations. Financial: people with low back pain want financial support, but have concerns about the inefficiencies of compensation systems and the stigma associated with financial remuneration. Social: people with low back pain report feeling disconnected from social networks and want back-specific social support. Household: people with low back pain report difficulties with household duties; however, there are few data regarding their need for auxiliary devices and domestic help. CONCLUSION: People with low back pain identified work place, financial and social pressures, and difficulties with household duties as areas of need beyond their healthcare requirements that affect their ability to comply with management of their condition. Consideration of such needs may inform physiotherapists, the wider health system, social networks and the workplace to provide more relevant and effective services.

PMID- 29574168 TI - Low leisure-based sitting time and being physically active were associated with reduced odds of death and diabetes in people with chronic obstructive pulmonary disease: a cohort study. AB - QUESTIONS: In people with chronic obstructive pulmonary disease (COPD), are activity phenotypes (based on physical activity and recreational screen time) associated with mortality and cardiometabolic risk factors? DESIGN: Cohort study. PARTICIPANTS: People with COPD aged>=40years and who were current or ex-smokers were identified from the 2003 Scottish Health Survey. OUTCOME MEASURES: Data were collected regarding demographics, anthropometric measurements, medical history, physical activity, sedentary behaviour, health outcomes, and mortality. ANALYSIS: Participants were categorised into one of the following activity phenotypes: 'couch potatoes' were those who were insufficiently active with high leisure based sitting time and/or no domestic physical activity; 'light movers' were insufficiently active with some domestic physical activity; 'sedentary exercisers' were sufficiently active with high leisure-based sitting time; and 'busy bees' were sufficiently active with low leisure-based sitting time. 'Sufficiently active' was defined as adhering to physical activity (PA) recommendations of>=7.5 metabolic equivalent (MET) hours/week. 'Low leisure-based sitting time' was defined as<=200minutes of recreational screen time/day. RESULTS: The 584 participants had a mean age of 64 years (SD 12) and 52% were male. Over 5.5 years (SD 1.3) of follow-up, there were 81 all-cause deaths from 433 COPD participants with available data. Compared to the 'couch potatoes', there was a reduced risk of all-cause mortality in the 'busy bees' (Hazard Ratio 0.26, 95% CI 0.11 to 0.65) with a trend towards a reduction in mortality risk in the other phenotypes. The odds of diabetes were lower in the 'busy bees' compared to the 'couch potatoes' (OR 0.14, 95% CI 0.03 to 0.67). CONCLUSIONS: Adhering to physical activity guidelines and keeping leisure-based sitting time low had a mortality benefit and lowered the odds of diabetes in people with COPD.

PMID- 29574170 TI - An education program about pelvic floor muscles improved women's knowledge but not pelvic floor muscle function, urinary incontinence or sexual function: a randomised trial. AB - QUESTION: Does an educational program with instructions for performing 'the Knack' improve voluntary contraction of the pelvic floor muscles, reduce reports of urinary incontinence, improve sexual function, and promote women's knowledge of the pelvic floor muscles? DESIGN: Randomised, controlled trial with concealed allocation, intention-to-treat analysis and blinded assessors. PARTICIPANTS: Ninety-nine women from the local community. INTERVENTION: The experimental group (n=50) received one lecture per week for 4 weeks, and instructions for performing 'the Knack'. The control group (n=49) received no intervention. OUTCOME MEASURES: The primary outcome was maximum voluntary contraction of the pelvic floor muscles measured using manometry. Secondary outcomes were: ability to contract the pelvic floor muscles measured using vaginal palpation; severity of urinary incontinence measured by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) scored from 0 to 21; self-reported sexual function; and knowledge related to the pelvic floor. Outcomes were measured at baseline and after 4 weeks. RESULTS: The intervention did not significantly improve: maximum voluntary contraction (MD 2.7 cmH2O higher in the experimental group, 95% CI -0.5 to 5.9); ability to contract the pelvic floor muscles (RR 2.18, 95% CI 0.49 to 9.65); or self-reported severity of urinary incontinence (MD 1 point greater reduction in the experimental group, 95% CI -3 to 1). Sexual function did not significantly differ between groups, but very few of the women engaged in sexual activity during the study period. The educational program did, however, significantly increase women's knowledge related to the location, functions and dysfunctions of the pelvic floor muscles, and treatment options. CONCLUSION: Education and teaching women to perform 'the Knack' had no significant effect on voluntary contraction of the pelvic floor muscles, urinary incontinence or sexual function, but it promoted women's knowledge about the pelvic floor.

AB - The role of adaptive immunity is increasingly recognized as an important element both in the process of tumorigenesis and in the patient's response to treatment. While this understanding has led to new therapeutic strategies that potentiate the activities of tumor infiltrating lymphocytes, only a minority of patients attain durable responses. Metabolic activities in the tumor microenvironment, including hypoxia and acidity, can adversely affect immune responses, making the identification of metabolic biomarkers critically important for understanding and employing immunotherapies. PMID- 29574172 TI - Concentration of the CDCP1 protein in human cord plasma may serve as a predictor of hematopoietic stem and progenitor cell content. AB - Successful hematopoietic stem and progenitor cell (HSPC) transplantation rests upon reliable methods for their enumeration in sources such as cord blood (CB). Methods used today are costly, time consuming and exhaust the limited number of cells needed for transplantation. The aim of this study was to analyze if surplus plasma from CB contains biomarkers that can predict HSPC content in CB. Frozen, surplus plasma from 95 CB units was divided into two groups based on CD34+ cell concentration. Birth weight, gestation age, gender, mode of delivery, collection volume, nucleated cell count and colony forming unit assay results were available. Samples were analyzed with a proximity ligation assay covering 92 different proteins. Two-group t-test with p-values adjusted for false discovery rate (FDR) identified 5 proteins that significantly differed between the two groups. CDCP1 was the most significant (FDR adjusted p-value 0.006). Correlation with CDCP1 concentration was most significant for CD34+ concentration and nucleated cell count. Multivariate analysis showed that CD34 and gender seemed to influence the level of CDCP1. In conclusion, CDCP1 was identified as a potential biomarker of HSPC content in CB. The finding also warrants further investigation for a possible role of CDCP1 in regulating HSPC presence in CB.

AB - Urine cells collected from 200mL clean midsection urine of a 25-year-old healthy man were reprogrammed into pluripotent stem cells via Sendai virus delivery system. The induced pluripotent stem cells showed a normal karyotype and exhibited the potential to differentiate into three germ layers in a teratoma assay. This cell line may serve as a useful control for comparison with other pluripotent stem cell lines induced from somatic cells of patients with genetic neurodegenerative disorders. PMID- 29574174 TI - Induced pluripotent stem cells-derived myeloid-derived suppressor cells regulate the CD8+ T cell response. AB - Myeloid-derived suppressor cells (MDSCs) are markedly increased in cancer patients and tumor-bearing mice and promote tumor growth and survival by inhibiting host innate and adaptive immunity. In this study, we generated and characterized MDSCs from murine-induced pluripotent stem cells (iPSCs). The iPSCs were co-cultured with OP9 cells, stimulated with GM-CSF, and became morphologically heterologous under co-culturing with hepatic stellate cells. Allogeneic and OVA-specific antigen stimulation demonstrated that iPS-MDSCs have a T-cell regulatory function. Furthermore, a popliteal lymph node assay and autoimmune hepatitis model showed that iPS-MDSCs also regulate immune responsiveness in vivo and have a therapeutic effect against hepatitis. Taken together, our results demonstrated a method of generating functional MDSCs from iPSCs and highlighted the potential of iPS-MDSCs as a key cell therapy resource for transplantation and autoimmune diseases. PMID- 29574175 TI - Developing Process Maps as a Tool for a Surgical Infection Prevention Quality Improvement Initiative in Resource-Constrained Settings. AB - BACKGROUND: Surgical infections cause substantial morbidity and mortality in low and middle-income countries (LMICs). To improve adherence to critical perioperative infection prevention standards, we developed Clean Cut, a checklist based quality improvement program to improve compliance with best practices. We hypothesized that process mapping infection prevention activities can help clinicians identify strategies for improving surgical safety. STUDY DESIGN: We introduced Clean Cut at a tertiary hospital in Ethiopia. Infection prevention standards included skin antisepsis, ensuring a sterile field, instrument decontamination/sterilization, prophylactic antibiotic administration, routine swab/gauze counting, and use of a surgical safety checklist. Processes were mapped by a visiting surgical fellow and local operating theater staff to facilitate the development of contextually relevant solutions; processes were reassessed for improvements. RESULTS: Process mapping helped identify barriers to using alcohol-based hand solution due to skin irritation, inconsistent administration of prophylactic antibiotics due to variable delivery outside of the operating theater, inefficiencies in assuring sterility of surgical instruments through lack of confirmatory measures, and occurrences of retained surgical items through inappropriate guidelines, staffing, and training in proper routine gauze counting. Compliance with most processes improved significantly following organizational changes to align tasks with specific process goals. CONCLUSIONS: Enumerating the steps involved in surgical infection prevention using a process mapping technique helped identify opportunities for improving adherence and plotting contextually relevant solutions, resulting in superior compliance with antiseptic standards. Simplifying these process maps into an adaptable tool could be a powerful strategy for improving safe surgery delivery in LMICs. PMID- 29574176 TI - Incidental Hypercalcemia and the Parathyroid. PMID- 29574177 TI - Robotic-Assisted Lobectomies in the National Cancer Database. AB - BACKGROUND: Robotic-assisted thoracoscopic surgery (RobATS) lobectomy is becoming more common for the treatment of lung cancer. As with any relatively new technology, there is the assumption that greater experience leads to greater proficiency. The objective of this study was to analyze outcomes of patients undergoing RobATS lobectomy as hospitals gain experience, and to describe outcomes after conversion to open procedures. STUDY DESIGN: The National Cancer Database (NCDB) was used to analyze robotic lobectomies for lung cancer from 2010 to 2014. Individual hospitals were categorized by the year they began reporting robotic lobectomies to the NCDB. Primary outcomes were perioperative morbidity and mortality and rate of conversion to open lobectomy. RESULTS: There were 7,645 robotic lobectomies identified from 465 hospitals. The overall conversion rate was 9.2% (n = 702). A propensity-matched analysis showed no significant difference between experienced and inexperienced hospitals with respect to 30-day mortality (1.07% vs 2.03%, p = 0.092) or 90-day mortality (2.35% vs 3.63%, p = 0.104). Conversion to open was a predictor of 30-day mortality (odds ratio [OR] 2.54, CI 1.56 to 4.14) and 90-day mortality (OR 2.68, CI 1.83 to 3.91). Patients who underwent conversion had higher 90-day mortality compared with patients not undergoing conversion, in years of experience: 2 (p = 0.043), 3 (p = 0.002), and 4 (p = 0.003). CONCLUSIONS: Mortality after RobATS lobectomy at experienced hospitals is not significantly different than at inexperienced hospitals. Though conversion rates decrease with experience, patients who undergo conversion have higher mortality than those who do not, particularly in hospitals with more experience. This suggests that a deliberate effort to increase experience with and improve patient selection for RobATS lobectomies may ameliorate the conversions and their attendant sequelae. PMID- 29574178 TI - Proposal of Prognostic Survival Models before and after Liver Resection for Hepatocellular Carcinoma in Potentially Transplantable Patients. AB - BACKGROUND: Transplantable hepatocellular carcinoma (HCC) represents a highly debated issue due to the overlap between indications for liver resection (LR) and transplantation (LT) in patients suitable for both. STUDY DESIGN: Between January 2000 and December 2012, five hundred and twenty-four transplantable patients affected by HCC were identified among resected patients. Two regression models were constructed to classify patients into 2 groups pre-low and pre-high risk based on preoperative variables and then to reclassify pre-low-risk patients according to postoperative variables into either post-low or post-high-risk. Additionally, a cohort of patients with comparable baseline characteristics who underwent LT were similarly classified into pre-low and pre-high-risk groups and compared with the resected patients in terms of survival. RESULTS: Cirrhosis, aspartate transaminase, alpha-fetoprotein, Model for End-Stage Liver Disease score, number of nodules, and diameter of the largest nodule were preoperatively found to be significantly related to overall survival post-LR. Microvascular invasion and satellites were selected to reclassify prognosis in the resulting preoperative low-risk group into post-high risk. The converted group (post-high) demonstrated the same 5-year survival as the pre-high group. Patients undergoing LT had better survival overall than those undergoing LR, with the exception of pre-low LT and post-low LR (confirmed low-risk LR) who had similar outcomes. CONCLUSIONS: The new models were strongly predictive of patients' likelihood of survival after LR for HCC on liver cirrhosis. Liver transplantation offers a survival advantage over LR, except in low-risk groups where both modalities might be comparable. PMID- 29574179 TI - External Validation and Optimization of the French Association of Hepatopancreatobiliary Surgery and Transplantation's Score to Predict Severe Postoperative Biliary Leakage after Open or Laparoscopic Liver Resection. AB - BACKGROUND: Biliary leakage is a major contributor to morbidity after hepatectomy. A score to predict severe posthepatectomy biliary leakage (PHBL) was recently developed by the French Association of Hepatopancreatobiliary Surgery and Transplantation (ACHBT). The aim of the study was to validate and optimize the score on an external cohort. STUDY DESIGN: The ACHBT score uses 5 factors (blood loss, remnant ischemia, anatomic resection of segment 8, transection along right aspect of the left intersectional plane and associating liver partition and portal vein ligation for staged hepatectomy) to predict severe PHBL. The score was tested on an external cohort of patients undergoing hepatectomy without hepaticojejunostomy between 1994 and 2016 at a single center. Association between the score, pre- and intraoperative variables, and severe PHBL was assessed in an attempt to improve the score. RESULTS: Among 778 procedures performed (including 679 [87.3%] laparoscopic and 260 [34.3%] major hepatectomies), 31 (4.0%) were complicated with severe PHBL. The ACHBT score showed good discrimination (AUROC [area under the receiver operating characteristic curve] 0.747, 95% CI 0.652 to 0.841), calibration and accuracy (diagnostic odds ratio for a score >=1: 6.217 [95% CI 2.642 to 14.627], for a score >=2: 6.059 [95% CI 2.858 to 12.846],and for a score >=3: 9.589 [95% CI 2.868 to 32.066]). On multivariable analysis, the ACHBT score was the only predictor of severe PHBL. A model combining the ACHBT score and conversion to open surgery was significantly more discriminating than the ACHBT score alone (AUROC 0.790 [95% CI 0.711 to 0.870], Delong's test p = 0.002). CONCLUSIONS: The ACHBT score represents an externally validated tool to predict severe PHBL. Inclusion of conversion to open surgery as an additional factor to the score allowed it to improve its performance to predict severe PHBL after laparoscopic hepatectomy. PMID- 29574180 TI - Venous Thromboembolism-Related Readmission in Emergency General Surgery Patients: A Role for Prophylaxis on Discharge? AB - BACKGROUND: Patients undergoing emergency general surgery (EGS) operations experience high rates of venous thromboembolism (VTE). The rates at which thrombus formation occurs after discharge, and whether VTE prophylaxis at discharge might be warranted to prevent readmission, are unknown. This analysis aimed to determine risk factors associated with VTE formation after discharge for EGS operations. STUDY DESIGN: An analysis of the American College of Surgeons NSQIP database from 2013 and 2014 of patients undergoing 10 common EGS operations in an emergent fashion. Multivariable logistic regression modeling was used to determine factors that predicted VTE after discharge. RESULTS: A total of 130,036 patients were included. The 30-day VTE rate was 1.30%, with 35% of all VTEs occurring after discharge. Of those who had VTE develop after discharge, 69.4% required readmission. Predictive factors for post-discharge VTE included prolonged length of stay (odds ratio [OR] 5.25; p < 0.001), presence of metastatic cancer (OR 2.23; p < 0.001), urinary tract infection (OR 1.91; p < 0.001), and postoperative sepsis (OR 1.55; p < 0.001). Identified high-risk groups had a rate of readmission with thrombus 6 times greater than that of average-risk EGS patients. CONCLUSIONS: More than 30% of VTEs in the EGS population occur after discharge; of these, a vast majority require readmission. Select high-risk EGS subgroups might benefit from prophylactic anticoagulation at discharge. PMID- 29574181 TI - Diversity and Distribution of Free-living Ciliates from High-Arctic Kara Sea Sediments. AB - For the first time, free-living ciliates were studied in sediments from a variety of habitats in the Kara Sea (the Arctic Ocean). Ciliates were found in a wide range of environmental conditions (from the intertidal zone up to depths of 554m, from salinities ranging from 0 to 34psu, and from coarse sands and gravel to muddy sediments), with total abundances varying from 1 to 127ind/cm3. Altogether, 114 species were identified, most of which were widely distributed and were previously reported from other Arctic regions. An unsaturated species accumulation curve and the presence of many rare species indicated that the Kara Sea is potentially as rich in ciliates as other regions. Fine- and medium-grained sands exhibited the richest and most abundant ciliate fauna, with many interstitial forms occurring up to depths of 200m; whereas both the coarse sands of the exposed intertidal beaches and the sublittoral muds were poorly inhabited by non-specific euryoecious species. The granulometric composition of sediments was suggested to be the main driver controlling the diversity and composition of ciliate communities, while the other factors, such as salinity, water productivity and depth, were of secondary importance. PMID- 29574182 TI - Tmem30a Plays Critical Roles in Ensuring the Survival of Hematopoietic Cells and Leukemia Cells in Mice. AB - The fundamental structure of eukaryotic cell plasma membrane is the phospholipid bilayer, which contains four major phospholipids. These phospholipids are asymmetrically distributed between the outer and inner leaflets. P4-ATPase flippase complexes play essential roles in ensuring this asymmetry. We found that conditional deletion of Tmem30a, the beta subunit of P4-ATPase flippase complex, caused pancytopenia in mice. Tmem30a deficiency resulted in depletion of lineage committed blood cells in the peripheral blood, spleen, and bone marrow. Ablation of Tmem30a also caused the depletion of hematopoietic stem cells (HSCs). HSC RNA sequencing results revealed that multiple biological processes and signal pathways were involved in the event, including mammalian target of rapamycin signaling, genes for HSC stemness, and genes responding to interferons. Our results also revealed that targeting Tmem30a signaling had therapeutic utility in BCR/ABL1-induced chronic myeloid leukemia. PMID- 29574183 TI - Random and oriented electrospun fibers based on a multicomponent, in situ clickable elastin-like recombinamer system for dermal tissue engineering. AB - : Herein we present a system to obtain fibers from clickable elastin-like recombinamers (ELRs) that crosslink in situ during the electrospinning process itself, with no need for any further treatment to stabilize them. These ELR-click fibers are completely stable under in vitro conditions. A wrinkled fiber morphology is obtained. In addition to a random fiber orientation, oriented fibers with a high degree of alignment and coherence can also be obtained by using a rotational electrode. The production of multicomponent fibers means that different functionalities, such as cell-adhesion domains (RGD peptides), can be incorporated into them. In a subsequent study, two main cell lines present in the dermis and epidermis, namely keratinocytes and fibroblasts, were cultured on top of the ELR-click fibers. Adhesion, proliferation, fluorescence, immunostaining and histology studies showed the cytocompatibility of these scaffolds, thus suggesting their possible use for wound dressings in skin tissue engineering applications. STATEMENT OF SIGNIFICANCE: For the first time stable electrospun bioactive fibers are obtained by the in situ mixing of two "clickable" ELR components previously described by Gonzalez et al (Acta Biomaterialia 2014). This work describes an efficient system to prepare fibrous scaffolds based on peptidic polymers by electrospinning without the need of crosslinking agents that could be harmful for cells or living tissues. These bioactive fibers support cell growth due to the inclusion of RGD motifs (Staubli et al. Biomaterials 2017). Finally, the in vitro biocompatibility of the two main cell types found in the outer layers of skin, fibroblasts and keratinocytes, indicates that this system is of great interest to prepare elastic artificial skin substitutes for wound healing applications. PMID- 29574184 TI - Engineering interfacial migration by collective tuning of adhesion anisotropy and stiffness. AB - : Interfacial migration is central to multiple processes including morphogenesis and wound healing. However, the sensitivity of interfacial migration to properties of the interfacial microenvironment has not been adequately explored. Here, we address this question by tracking motility of 3T3 fibroblasts at the interface of two hydrogels. By sandwiching cells between two adhesive gels (composed of methacrylated gelatin) or between an adhesive and a non-adhesive gel (composed of gellan), we show that cells are more motile in case of the latter. By tuning the bulk stiffness of the gellan gel, we then show that motility is tuned in a stiffness-dependent manner. Fastest motility observed in case of the stiffest gel was associated with increased cell height, suggestive of stiffness mediated cytoskeletal assembly. Inhibition of cell motility by contractile agonists and actin depolymerizing drugs is indicative of a mode of migration wherein cells combine contractile tractions exerted at their base and actin-based pushing forces on the top surface to propel themselves forward. Together, our results suggest that dorso-ventral adhesion anisotropy and stiffness can be collectively tuned to engineer interfacial migration. STATEMENT OF SIGNIFICANCE: It is increasingly understood that cells migrate in vivo through confining spaces which typically occur as pores in the matrix and through naturally occurring interfaces that exist between neighbouring ECM fibers, or between the stroma and the vasculature. Such interfaces are also created when treating wounds on the skin surface by covering the wounds with adhesives. How multiple cues impact interfacial migration has not been adequately addressed. By studying cell migratory behaviour at the interface of two hydrogel substrates, we identify adhesivity and stiffness as two critical factors that can be tuned to maximize cell migration. We foresee a potential use of this knowledge in the design of tissue adhesives for wound healing applications. PMID- 29574185 TI - Collagen fiber recruitment: A microstructural basis for the nonlinear response of the posterior pole of the eye to increases in intraocular pressure. AB - : Our goal was to quantify and characterize how the collagen fiber crimp waviness of the lamina cribrosa (LC) and peripapillary sclera (PPS) changes with intraocular pressure (IOP). Thirteen sheep (ovine) eyes were immersion and perfusion fixed while maintaining IOP at 0, 10, 15, 20, or 50 mmHg. Coronal optic nerve head (ONH) sections (30 um) were imaged with polarized light microscopy (PLM) and analyzed for collagen fiber orientation and waviness (SD of fiber orientation). In the LC, the waviness of every LC beam was measured. In the PPS, at least 900 collagen bundles were measured per eye. Using the waviness at 50 mmHg IOP, we defined tissue-specific thresholds to determine the fraction of loaded or recruited fibers. We found that fiber waviness decreased with IOP (P < 0.001). At every IOP, the waviness of the collagen fibers, and the fraction of fibers recruited in the LC were smaller or equal than those of the PPS (P < 0.001). At 15 mmHg IOP, both LC and PPS had 3/4 recruited fibers and 1/4 left in reserve. The decreased waviness with IOP and associated fiber recruitment is experimental evidence of fiber-based nonlinear biomechanical behavior of the ONH. At all IOPs the PPS had an equal or larger fraction of fibers recruited than the LC. That both LC and PPS had the same fraction of recruited and reserve fibers at normal IOP suggests that this may be an optimal fraction of recruitment for healthy eyes. Whether this extends to human eyes remains unknown. STATEMENT OF SIGNIFICANCE: Collagen fibers exhibit a natural waviness or crimp that largely determine the nonlinear biomechanics of soft tissue. Experimental measurements of crimp morphology in the sheep eye, and how it changes with intraocular pressure (IOP), however, are exceedingly sparse. We quantified how posterior eye crimp changes with increasing IOP. We found that the lamina cribrosa and peripapillary sclera have fundamentally different crimp, and with increasing IOP, have different proportions of fibers that straighten, or get recruited, versus remaining wavy, or in reserve. Interestingly, at physiologic IOP of 15 mmHg, both tissues had about 3/4 fibers recruited and 1/4 fibers in reserve, indicating there may be an optimal fraction of fibers. PMID- 29574186 TI - miR-205-5p negatively regulates hepatic acetyl-CoA carboxylase beta mRNA in lipid metabolism of Oreochromis niloticus. AB - MicroRNAs (miRNAs) are non-coding RNAs that function as post-transcriptional gene regulators and that play vital roles controlling lipid metabolism. miR-205 is an important miRNA related to adipogenesis and lipid metabolism. However, little is known about the potential role of miR-205-5p in genetically improved farmed tilapia (GIFT, Oreochromis niloticus). In this study, we used miRanda software to search for potential miR-205-5p target genes and found a lipid-metabolism-related gene called acetyl-CoA carboxylase beta (ACACbeta). Quantitative real-time polymerase chain reaction data indicated that there may be a negative regulation relationship between miR-205-5p and ACACbeta gene expression under HFD rearing. Using luciferase reporter assays, we verified the binding site of miR-205-5p in the 3'-untranslated region of the ACACbeta mRNA. Furthermore, an in vivo functional analysis of miR-205-5p was performed by injecting GIFT juveniles with a miR-205-5p antagomir. Reduced levels of miR-205-5p in GIFT liver increased ACACbeta mRNA expression 12 h post-injection. miR-205-5p suppression also increased fatty acid synthase and peroxisome proliferator-activated receptor alpha mRNA levels 48 h and 120 h post-injection, respectively. Taken together, our results indicate that miR-205-5p negative regulates hepatic ACACbeta mRNA expression, and may serve as an important regulator in controlling hepatic lipid metabolism in GIFT. PMID- 29574187 TI - The analyses of relationships among nucleotide, synonymous codon and amino acid usages for E2 gene of bovine viral diarrhea virus. AB - In this study, the systemic analyses of nucleotide, codon and amino acid usages for E2 gene of bovine viral diarrhea virus (BVDV) were carried out for estimating its genetic features. The nucleotide usage pattern at the first codon position was strongly influenced by the overall nucleotide composition, while the nucleotide usage patterns at the second and third codon positions seemed to have little link to the overall nucleotide composition. The result indicated that the mutation pressure from nucleotide composition constraint was not the single evolutionary force for genetic features of BVDV E2 gene. Just 18 out of 59 synonymous codons were similar with synonymous codon usage patterns for E2 gene between BVDV1 and BVDV2, while all synonymous codons which contain CpG dinucleotides were selected at the low level by E2 gene, suggesting that this gene suppressed the usages of codons containing CpG dinucleotides to regulate E2 gene replicate and transcript efficiently and avoid immune response from infected hosts. Amino acid usage patterns of E2 protein were generally different between BVDV1 and BVDV2. The patterns of synonymous codon and amino acid usages for E2 gene might be caused by the equilibrium of evolutionary forces from virus and host. Our work gave new investigations into the role of host origin in the formations of synonymous codon/amino acid usages and the evolutionary trend of BVDV E2 gene. The genetic characteristics that codon/amino acid usages of E2 gene adapted to the internal environment of individual animals might assist in understanding the changes of genetics and antigenicity for newly emerging BVDV. PMID- 29574188 TI - New bifunctional restriction-modification enzyme AloI isoschizomer (PcoI): Bioinformatics analysis, purification and activity confirmation. AB - Type II restriction endonucleases and modification DNA-methyltransferases are key instruments of genetic engineering. Recently the number of proteins assigned to this group exceeds 8500. Subtype IIC organizes bifunctional endonuclease methyltransferase enzymes and currently consists of 16 described members. Here we present phylogenetic tree of 22 new potential bifunctional endonucleases. The majority of them are thought to be fusions of a restriction nuclease with a DNA methyltransferase and a target recognition subunit of type I restriction modification systems (R-M-S structure). A RM.AloI isoschizomer from Prevotella copri DSM-18205, PcoI, has been cloned, purified and its REase activity demonstrated. It cuts DNA in magnesium-dependent manner and demonstrates high affinity to DNA, which probably reflects its mechanism of action. This work provides additional proves that gene fusion might play an important role in evolution of restriction-modification systems and other DNA-modifying proteins. PMID- 29574189 TI - Comparative antennal transcriptome of Apis cerana cerana from four developmental stages. AB - Apis cerana cerana, an important endemic honey bee species in China, possesses valuable characteristics such as a sensitive olfactory system, good foraging ability, and strong resistance to parasitic mites. Here, we performed transcriptome sequencing of the antenna, the major chemosensory organ of the bee, using an Illumina sequencer, to identify typical differentially expressed genes (DEGs) in adult worker bees of different ages, namely, T1 (1 day); T2 (10 days); T3 (15 days); and T4 (25 days). Surprisingly, the expression levels of DEGs changed significantly between the T1 period and the other three periods. All the DEGs were classified into 26 expression profiles by trend analysis. Selected trend clusters were analyzed, and valuable information on gene expression patterns was obtained. We found that the expression levels of genes encoding cuticle proteins declined after eclosion, while those of immunity-related genes increased. In addition, genes encoding venom proteins and major royal jelly proteins were enriched at the T2 stage; small heat shock proteins showed significantly higher expression at the T3 stage; and some metabolism-related genes were more highly expressed at the T4 stage. The DEGs identified in this study may serve as a valuable resource for the characterization of expression patterns of antennal genes in A. cerana cerana. Furthermore, this study provides insights into the relationship between labor division in social bees and gene function. PMID- 29574190 TI - The transcriptome analyses of Tagetes erecta provides novel insights into secondary metabolite biosynthesis during flower development. AB - Genomic and transcriptomic sequences of Tagetes erecta are very limited in public databases, despite its nutritional and economical value. In this study, nine cDNA libraries were constructed from leaves, immature and mature flowers and sequenced using Illumina Hiseq 2000. Over 45.66 Gb nucleotides were generated and a total of 72,499 unigenes were assembled, 34,892 (48.13%) of which were annotated in NR, Swiss-prot, COG, GO, KOG, KEGG and Pfam. 11,721 differentially expressed genes were identified in leaves, immature flowers and mature flowers. The differentially expressed genes between immature flowers and mature flowers were mainly involved in photosynthesis and secondary metabolite biosynthesis. Additionally, the catalysis-related unigenes and their expression involved in carotenoids biosynthesis were determined. Using our newly identified reference genes as internal control, the expression profiles of carotenoids biosynthetic genes were verified by real-time qRT-PCR, and four of the unigenes were cloned for full length sequences confirmation. Furthermore, gene expansions occurred among the catalytic gene families in carotenoids biosynthesis pathway, which might explain the high pigment content in T. erecta. PMID- 29574191 TI - The acroframosome-acroplaxome-manchette axis may function in sperm head shaping and male fertility. AB - Sperm malformation is one of the main reasons for male infertility, but the precise mechanisms of this process remain undiscovered. The major process of spermiogenesis is sperm head shaping. Cytoskeleton is a crucial unit in this process, as the acroplaxome and manchette are two kinds of momentous structures cooperated with various functional proteins to insure the formation of acrosome and nucleus. One is primarily formed by filamentous actin (F-actin) and responsible for transverse acrosome extension and concentration, another plays as the mainstay of nuclear deformation through circular arrangement of microtubules (MTs). We suspect that the acroplaxome alone cannot maintain such a spatial framework of the acrosome. Previous studies have also revealed that a nucleus without acrosome could not induce the formation of ectoplasmic specialization. In this review, we integrated most of the key proteins that have been proven to participate in the essential developmental steps of post-meiosis. We also propose that the ambient MTs of the acrosome might be emanated from the Golgi apparatus. They form a novel cytoskeleton termed acroframosome (AFS) to transport vesicles and proteins during acrosome biogenesis. The hypothesis of the acroframosome acroplaxome-manchette (AAM) cytoskeletal system is likely to be the axis of head to-tail spermiogenesis. PMID- 29574192 TI - Comprehensive analysis of differentially expressed genes reveals the molecular response to elevated CO2 levels in two sea buckthorn cultivars. AB - Atmospheric carbon dioxide (CO2) concentration increases every year. It is critical to understand the elevated CO2 response molecular mechanisms of plants using genomic techniques. Hippophae rhamnoides L. is a high stress resistance plant species widely distributed in Europe and Asia. However, the molecular mechanism of elevated CO2 response in H. rhamnoides has been limited. In this study, transcriptomic analysis of two sea buckthorn cultivars under different CO2 concentrations was performed, based on the next-generation illumina sequencing platform and de novo assembly. We identified 4740 differentially expressed genes in sea buckthorn response to elevated CO2 concentrations. According to the gene ontology (GO) results, photosystem I, photosynthesis and chloroplast thylakoid membrane were the main enriched terms in 'xiangyang' sea buckthorn. In 'zhongguo' sea buckthorn, photosynthesis was also the main significantly enriched term. However, the number of photosynthesis related differentially expressed genes were different between two sea buckthorn cultivars. Our GO and pathway analyses indicated that the expression levels of the transcription factors WRKY, MYB and NAC were significantly different between the two sea buckthorn cultivars. This study provides a reliable transcriptome sequence resource and is a valuable resource for genetic and genomic researches for plants under high CO2 concentration in the future. PMID- 29574193 TI - Nonclinical assessments of the potential biosimilar PF-06439535 and bevacizumab. AB - Bevacizumab, a recombinant humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF), is approved for treatment of metastatic colorectal cancer, nonsquamous non-small-cell lung cancer, metastatic kidney cancer, and glioblastoma. To support clinical development of the potential bevacizumab biosimilar PF-06439535, nonclinical studies evaluated structural, functional, toxicological, and toxicokinetic similarity to bevacizumab sourced from the European Union (bevacizumab-EU) and United States (bevacizumab-US). Peptide mapping demonstrated the amino acid sequence of PF-06439535 was identical to bevacizumab-EU and bevacizumab-US. Biologic activity, measured via inhibition of VEGF-induced cell proliferation in human umbilical vein endothelial cells and binding to VEGF isoforms, was similar across the three drugs. In vivo similarity was demonstrated in cynomolgus monkeys administered intravenous PF-06439535 or bevacizumab-EU (0 or 10 mg/kg/dose twice weekly for 1 month; total of nine doses). Systemic exposure appeared similar and test article-related effects were limited to physeal dysplasia of the distal femur. The potential for non-target mediated toxicity of PF-06439535 was evaluated in rats administered intravenous PF-06439535 (15 or 150 mg/kg/dose twice weekly for 15 days; total of five doses). Nonadverse higher liver weights and minimal sinusoidal cell hyperplasia were observed. Collectively, these studies demonstrated similarity of PF-06439535 to bevacizumab, supporting entry into clinical development. PMID- 29574194 TI - Repeated dose 90-day oral toxicity test of G-7% NANA in rats: An application of new criterion for toxicity determination to test article-induced changes. AB - G-7% NANA is N-acetylneuraminic acid(NANA) containing 7% sialic acid isolated from glycomacropeptide (GMP), a compound of milk. Since NANA is likely to have immunotoxicity, the need to ensure safety for long-term administration has been raised. In this study, a 90-day repeated oral dose toxicity test was performed in rats using G-7% NANA in the dosages of 0, 1250, 2500 and 5000 mg/kg/day.A toxicity determination criterion based on the significant change caused by the administration of the substancewas developed for estimating NOEL, NOAEL and LOAELapplied to this study. When analyzing the immunological markers, no significant changes were observed, even if other significant changes were observed in the high dose group. In accordance with the toxicity determination criterion developed, the NOEL in male and female has been determined as 2500 mg/kg/day, and the NOAEL in females has been determined as 5000 mg/kg/day. The toxicity determination criterion, applied for the first time in the repeated dose toxicity tests, could provide a basis for distinguishing NOEL and NOAEL more clearly; nevertheless, the toxicity determination criterion needs to be supplemented by adding differentiating adverse effects and non-adverse effects based on more experiences of the repeated dose toxicity tests.

AB - The present meta-analytic study examined brain activation changes following working memory (WM) training, a form of cognitive training that has attracted considerable interest. Comparisons with perceptual-motor (PM) learning revealed that WM training engages domain-general large-scale networks for learning encompassing the dorsal attention and salience networks, sensory areas, and striatum. Also the dynamics of the training-induced brain activation changes within these networks showed a high overlap between WM and PM training. The distinguishing feature for WM training was the consistent modulation of the dorso and ventrolateral prefrontal cortex (DLPFC/VLPFC) activity. The strongest candidate for mediating transfer to similar untrained WM tasks was the frontostriatal system, showing higher striatal and VLPFC activations, and lower DLPFC activations after training. Modulation of transfer-related areas occurred mostly with longer training periods. Overall, our findings place WM training effects into a general perception-action cycle, where some modulations may depend on the specific cognitive demands of a training task.

AB - The commercialization of engineered nanomaterials (ENMs) began in the early 2000's. Since then the number of commercial products and the number of workers potentially exposed to ENMs is growing, as is the need to evaluate and manage the potential health risks. Occupational exposure limits (OELs) have been developed for some of the first generation of ENMs. These OELs have been based on risk assessments that progressed from qualitative to quantitative as nanotoxicology data became available. In this paper, that progression is characterized. It traces OEL development through the qualitative approach of general groups of ENMs based primarily on read-across with other materials to quantitative risk assessments for nanoscale particles including titanium dioxide, carbon nanotubes and nanofibers, silver nanoparticles, and cellulose nanocrystals. These represent prototypic approaches to risk assessment and OEL development for ENMs. Such substance-by-substance efforts are not practical given the insufficient data for many ENMs that are currently being used or potentially entering commerce. Consequently, categorical approaches are emerging to group and rank ENMs by hazard and potential health risk. The strengths and limitations of these approaches are described, and future derivations and research needs are discussed. Critical needs in moving forward with understanding the health effects of the numerous EMNs include more standardized and accessible quantitative data on the toxicity and physicochemical properties of ENMs. PMID- 29574198 TI - Pilot-scale evaluation of micropollutant abatements by conventional ozonation, UV/O3, and an electro-peroxone process. AB - The electro-peroxone (E-peroxone) process is an emerging ozone-based advanced oxidation process (AOP) that has shown large potential for micropollutant abatement in water treatment. To evaluate its performance under more realistic conditions of water treatment, a continuous-flow pilot E-peroxone system was developed and compared with conventional ozonation and a UV/O3 process for micropollutant abatements in various water matrices (groundwater, surface water, and secondary wastewater effluent) in this study. With a specific ozone dose of 1.5 mg O3/mg DOC, micropollutants that have high and moderate reactivity with ozone (O3) (diclofenac, naproxen, gemfibrozil, and bezafibrate) could be sufficiently abated (>90% abatement) in the various waters by all three processes. However, ozone-resistant micropollutants (ibuprofen, clofibric acid, and chloramphenicol) were abated only by ~32-68%, 68-91%, and 73-90% during conventional ozonation of the selected groundwater, surface water, and secondary wastewater effluent, respectively. By electro-generating H2O2 or applying UV irradiation to enhance O3 transformation to *OH during ozonation, the E-peroxone and UV/O3 processes similarly enhanced the abatement efficiencies of ozone resistant micropollutants by ~15-43%, ~5-15%, and ~5-10% in the groundwater, surface water, and secondary wastewater effluent, respectively. In addition, the E-peroxone and UV/O3 processes significantly reduced bromate formation during the treatment of the three waters compared to conventional ozonation. Due to its higher efficiency, the E-peroxone process reduced ~10-53% of the energy consumption required to abate the concentration of chloramphenicol (the most ozone-resistant micropollutant spiked in the waters) by 1 order of magnitude in the three waters compared to conventional ozonation. In contrast, the UV/O3 process consumed approximately 4-10 times higher energy than conventional ozonation. This pilot-scale study demonstrates that the E-peroxone process can provide a feasible, effective, and energy-efficient alternative for micropollutant abatement and bromate control in water and wastewater treatment. PMID- 29574199 TI - Successful aerobic bioremediation of groundwater contaminated with higher chlorinated phenols by indigenous degrader bacteria. AB - The xenobiotic priority pollutant pentachlorophenol has been used as a timber preservative in a polychlorophenol bulk synthesis product containing also tetrachlorophenol and trichlorophenol. Highly soluble chlorophenol salts have leaked into groundwater, causing severe contamination of large aquifers. Natural attenuation of higher-chlorinated phenols (HCPs: pentachlorophenol + tetrachlorophenol) at historically polluted sites has been inefficient, but a 4 year full scale in situ biostimulation of a chlorophenol-contaminated aquifer by circulation and re-infiltration of aerated groundwater was remarkably successful: pentachlorophenol decreased from 400 MUg L-1 to <1 MUg L-1 and tetrachlorophenols from 4000 MUg L-1 to <10 MUg L-1. The pcpB gene, the gene encoding pentachlorophenol hydroxylase - the first and rate-limiting enzyme in the only fully characterised aerobic HCP degradation pathway - was present in up to 10% of the indigenous bacteria already 4 months after the start of aeration. The novel quantitative PCR assay detected the pcpB gene in situ also in the chlorophenol plume of another historically polluted aquifer with no remediation history. Hotspot groundwater HCPs from this site were degraded efficiently during a 3-week microcosm incubation with one-time aeration but no other additives: from 5400 MUg L-1 to 1200 MUg L-1 and to 200 MUg L-1 in lightly and fully aerated microcosms, respectively, coupled with up to 2400% enrichment of the pcpB gene. Accumulation of lower-chlorinated metabolites was observed in neither in situ remediation nor microcosms, supporting the assumption that HCP removal was due to the aerobic degradation pathway where the first step limits the mineralisation rate. Our results demonstrate that bacteria capable of aerobic mineralisation of xenobiotic pentachlorophenol and tetrachlorophenol can be present at long-term polluted groundwater sites, making bioremediation by simple aeration a viable and economically attractive alternative. PMID- 29574200 TI - Effective phosphate removal for advanced water treatment using low energy, migration electric-field assisted electrocoagulation. AB - A migration electric-field assisted electrocoagulation (MEAEC) system was developed to increase phosphate removal from domestic wastewater, with reduced energy consumption, using a titanium charging (inert) electrode and a sacrificial iron anode. In the MEAEC, an electric field was applied between the inert electrode (titanium) and an air cathode to drive migration of phosphate anions towards the sacrificial anode. Current was then applied between the sacrificial anode (Fe or Al mesh) and the air cathode to drive electrocoagulation of phosphate. A MEAEC with the Fe electrode using primary clarifier effluent achieved 98% phosphate removal, producing water with a total phosphorus of 0.3 mg/L with <6 min total treatment time (five cycles; each 10 s inert electrode charging, and 1 min electrocoagulation), at a constant current density of 1 mA/cm2. In the absence of the 10 s charging time, electrocoagulation required 15 min for the same removal. With an aluminum anode and the same phosphorus removal, the MEAEC required 7 cycles (7 min total treatment, 1 min 10 s total charging), while conventional electrocoagulation required 20 min. The energy demand of Fe MEAEC was only 0.039 kWh/m3 for 98% phosphate removal, which was 35% less than with the Al-MEAEC of 0.06 kWh/m3, and 28% less than that previously obtained using an inert graphite electrode. Analysis of the precipitate showed that a less porous precipitate was obtained with the Al anode than with the Fe anode. The phosphorus in precipitate of Fe-MEAEC was identified as PO43- and HPO42-, while the Fe was present as both Fe2+ and Fe3+. Only HPO42- and Al3+ were identified in the precipitate of the Al-MEAEC. These results indicated that the MEAEC with a titanium inert charging electrode and iron anode could achieve the most efficient phosphate removal with very low energy demands, compared to previous electrochemical approaches. PMID- 29574201 TI - Enhanced pharmaceutical removal from water in a three step bio-ozone-bio process. AB - Individual treatment processes like biological treatment or ozonation have their limitations for the removal of pharmaceuticals from secondary clarified effluents with high organic matter concentrations (i.e. 17 mg TOC/L). These limitations can be overcome by combining these two processes for a cost-effective pharmaceutical removal. A three-step biological-ozone-biological (BO3B) treatment process was therefore designed for the enhanced pharmaceutical removal from wastewater effluent. The first biological step removed 38% of ozone scavenging TOC, thus proportionally reducing the absolute ozone input for the subsequent ozonation. Complementariness between biological and ozone treatment, i.e. targeting different pharmaceuticals, resulted in cost-effective pharmaceutical removal by the overall BO3B process. At a low ozone dose of 0.2 g O3/g TOC and an HRT of 1.46 h in the biological reactors, the removal of 8 out of 9 pharmaceuticals exceeded 85%, except for metoprolol (60%). Testing various ozone doses and HRTs revealed that pharmaceuticals were ineffectively removed at 0.1 g O3/g TOC and an HRT of 0.3 h. At HRTs of 0.47 and 1.46 h easily and moderately biodegradable pharmaceuticals such as caffeine, gemfibrozil, ibuprofen, naproxen and sulfamethoxazole were over 95% removed by biological treatment. The biorecalcitrant carbamazepine was completely ozonated at a dose of 0.4 g O3/g TOC. Ozonation products are likely biodegraded in the last biological reactor as a 17% TOC removal was found. No appreciable acute toxicity towards D. magna, P. subcapitata and V. fischeri was found after exposure to the influents and effluents of the individual BO3B reactors. The BO3B process is estimated to increase the yearly wastewater treatment tariff per population equivalent in the Netherlands by less than 10%. Overall, the BO3B process is a cost-effective treatment process for the removal of pharmaceuticals from secondary clarified effluents. PMID- 29574202 TI - Structure-based design of bacterial transglycosylase inhibitors incorporating biphenyl, amine linker and 2-alkoxy-3-phosphorylpropanoate moieties. AB - Transglycosylase (TGase) is essential to biosynthesis of peptidoglycan for formation of bacterial cell wall. Moenomycin is a potent TGase inhibitor, but not used in clinic treatment due to its poor pharmacokinetics. The E-F disaccharide, phosphoglycerate and lipid tail in moenomycin are crucial elements for TGase inhibition and antibacterial activity. Based on this scaffold, a series of truncated mimics comprising biphenyl, amine linker and 2-alkoxy-3 phosphorylpropanoate moieties were designed to test their TGase inhibitory activity. In this design, the phosphorylpropanoate group is a surrogate of phosphoglycerate with improved stability. A library of lipid tails can be constructed by a straightforward approach using Cu(I)-catalyzed (3 + 2) cycloaddition reactions, and the as-synthesized triazole ring can provide additional hydrogen bonds in the TGase active site. Our molecular docking experiments reveal that the biphenyl group provides pi-pi and pi-cation interactions to act as a simplified alternative of the C-E disaccharide in moenomycin. To play the role of the oxonium transition state in transglycosylation, the amine linker exists as a positively charged species in physiological condition to attain electrostatic interactions with acidic residues. In this study, two biphenyl-linked 2-alkoxy-3-phosphorylpropanoate compounds (8 and 10) are found to exhibit modest inhibitory activity (IC50 ~ 150 MUM) against the TGase of Acinetobacter baumannii and good antibacterial activity against Staphylococcus aureus (MIC = 6.3 MUM). PMID- 29574203 TI - Inhibitors of phosphodiesterase as cancer therapeutics. AB - Phosphodiesterases (PDEs) are a class of enzymes that hydrolyze cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) which is involved in many physiological processes including visual transduction, cell proliferation and differentiation, cell-cycle regulation, gene expression, inflammation, apoptosis, and metabolic function. PDEs are composed of 11 different families and each family contains different subtypes. The distribution, expression, regulation mode and sensitivity to inhibitors of each subtype are different, and they are involved in cancer, inflammation, asthma, depression, erectile dysfunction and other pathological processes of development. A large number of studies have shown that PDEs play an important role in the development of tumors by affecting the intracellular level of cAMP and/or cGMP and PDEs could become diagnostic markers or therapeutic targets. This review will give a brief overview of the expression and regulation of PDE families in the process of tumorigenesis and their anti tumor inhibitors, which may guide the design of novel therapeutic drugs targeting PDEs for anticancer agent. PMID- 29574204 TI - Design and synthesis of aryloxypropanolamine as beta3-adrenergic receptor antagonist in cancer and lipolysis. AB - beta-adrenergic receptors (beta-ARs) are broadly distributed in various tissues and regulate a panel of important physiological functions and disease states including cancer. Above all, beta3-adrenergic receptor (beta3-AR) plays a significant role in regulating lipolysis and thermogenesis in adipose tissue. In this study, we designed and synthesized a series of novel L-748,337 derivatives as selective human beta3-AR antagonists. Among all the tested L-748,337 analogs, compound 23d was found to display 23-fold more potent beta3-AR antagonist activity (EC50 = 0.5117 nM) than L-748,337 (EC50 = 11.91 nM). In vivo, compound 23d could alleviate weight loss and inhibit tumor growth in C26 tumor cachexia animal model. PMID- 29574205 TI - DSM-flux: A new technology for reliable Combined Sewer Overflow discharge monitoring with low uncertainties. AB - In the past ten years, governments from the European Union have been encouraged to collect volume and quality data for all the effluent overflows from separated stormwater and combined sewer systems that result in a significant environmental impact on receiving water bodies. Methods to monitor and control these flows require improvements, particularly for complex Combined Sewer Overflow (CSO) structures. The DSM-flux (Device for Stormwater and combined sewer flows Monitoring and the control of pollutant fluxes) is a new pre-designed and pre calibrated channel that provides appropriate hydraulic conditions suitable for measurement of overflow rates and volumes by means of one water level gauge. In this paper, a stage-discharge relation for the DSM-flux is obtained experimentally and validated for multiple inflow hydraulic configurations. Uncertainties in CSO discharges and volumes are estimated within the Guide to the expression of Uncertainty in Measurement (GUM) framework. Whatever the upstream hydraulic conditions are, relative uncertainties are lower than 15% and 2% for the investigated discharges and volumes, respectively. PMID- 29574206 TI - Full-scale effects of addition of sludge from water treatment stations into processes of sewage treatment by conventional activated sludge. AB - An emerging practice for water treatment plant (WTP) sludge is its disposal in wastewater treatment plants (WWTP), an alternative that does not require the installation of sludge treatment facilities in the WTP. This practice can cause both positive and negative impacts in the WWTP processes since the WTP sludge does not have the same characteristics as domestic wastewater. This issue gives plenty of information in laboratory and pilot scales, but lacks data from full scale studies. The main purpose of this paper is to study the impact of disposing sludge from the Rio Grande conventional WTP into the ABC WWTP, an activated sludge process facility. Both plants are located in Sao Paulo, Brazil, and are full-scale facilities. The WTP volumetric flow rate (4.5 m3/s) is almost three times that of WWTP (1.6 m3/s). The data used in this study came from monitoring the processes at both plants. The WWTP liquid phase treatment analysis included the variables BOD, COD, TSS, VSS, ammonia, total nitrogen, phosphorus and iron, measured at the inlet, primary effluent, mixed liquor, and effluent. For the WWTP solids treatment, the parameters tested were total and volatile solids. The performance of the WWTP process was analyzed with and without sludge addition: 'without sludge' in years 2005 and 2006 and 'with sludge' from January 2007 to March 2008. During the second period, the WTP sludge addition increased the WWTP removal efficiencies for solids (93%-96%), organic matter (92%-94% for BOD) and phosphorus (52%-88%), when compared to the period 'without sludge'. These improvements can be explained by higher feed concentrations combined to same or lower effluent concentrations in the 'with sludge' period. No critical negative impacts occurred in the sludge treatment facilities, since the treatment units absorbed the extra solids load from the WTP sludge. PMID- 29574207 TI - Making the best use of experts' estimates to prioritise monitoring and management actions: A freshwater case study. AB - Under limited time and resources, ecological managers are under increasing pressure to demonstrate tangible impact of monitoring activities. Value of Information (VOI) has been advocated as an ideal tool to evaluate whether more data is required to improve expected management outcomes. Yet, despite several recent works explaining its value, VOI remains seldom used in practice. Here we provide an example of a successful ecological application of VOI. We apply VOI to a novel multi-objective freshwater management problem and show how to make the best use of expert data through a robust sensitivity analysis. Unlike previous VOI approaches, our analysis provides statistical confidence to our recommendations. We apply our approach to the recovery of Moira grass (Pseudoraphis spinescens) plains, a threatened vegetation community at the Ramsar listed Barmah Forest on the Murray River, Australia. Working closely with managers, we discovered that although many threats may impede Moira grass recovery, reducing grazing pressure and applying ideal depth and duration of flooding were most likely to lead to recovery. We found that learning from monitoring can significantly increase the existing extent of Moira grass, although these gains are modest compared to immediate management action. Our study shows how VOI can be used to demonstrate efficient use of limited environmental water to maximise ecological impact and increase transparency when making monitoring or management decisions. More broadly, the study methods will be of interest to any environmental manager who needs to prioritise monitoring and evaluation activities subject to a limited research budget. At a time where researchers and managers are asked to be more accountable for their decision making, VOI provides a very accessible tool that can speed up the decision of whether to wait and collect more data or act immediately despite uncertainty. PMID- 29574208 TI - An optimization model for carbon capture & storage/utilization vs. carbon trading: A case study of fossil-fired power plants in Turkey. AB - We consider fossil-fired power plants that operate in an environment where a cap and trade system is in operation. These plants need to choose between carbon capture and storage (CCS), carbon capture and utilization (CCU), or carbon trading in order to obey emissions limits enforced by the government. We develop a mixed-integer programming model that decides on the capacities of carbon capture units, if it is optimal to install them, the transportation network that needs to be built for transporting the carbon captured, and the locations of storage sites, if they are decided to be built. Main restrictions on the system are the minimum and maximum capacities of the different parts of the pipeline network, the amount of carbon that can be sold to companies for utilization, and the capacities on the storage sites. Under these restrictions, the model aims to minimize the net present value of the sum of the costs associated with installation and operation of the carbon capture unit and the transportation of carbon, the storage cost in case of CCS, the cost (or revenue) that results from the emissions trading system, and finally the negative revenue of selling the carbon to other entities for utilization. We implement the model on General Algebraic Modeling System (GAMS) by using data associated with two coal-fired power plants located in different regions of Turkey. We choose enhanced oil recovery (EOR) as the process in which carbon would be utilized. The results show that CCU is preferable to CCS as long as there is sufficient demand in the EOR market. The distance between the location of emission and location of utilization/storage, and the capacity limits on the pipes are an important factor in deciding between carbon capture and carbon trading. At carbon prices over $15/ton, carbon capture becomes preferable to carbon trading. These results show that as far as Turkey is concerned, CCU should be prioritized as a means of reducing nation-wide carbon emissions in an environmentally and economically rewarding manner. The model developed in this study is generic, and it can be applied to any industry at any location, as long as the required inputs are available. PMID- 29574209 TI - Degradation of Penicillin G by heat activated persulfate in aqueous solution. AB - We used Heat Activated of Persulfate (HAP) to decompose Penicillin G (PEN G) in aqueous solution. The effect of pH (3-11), temperature (313-353 K), and initial concentration of Sodium Persulfate (SPS) (0.05-0.5 mM) on the decomposition level of PEN G were investigated. The residue of PEN G was determined by spectrophotometry at the wavelength of 290 nm. Also, the Chemical Oxygen Demand (COD) was measured in each experiment. The Total Organic Carbon (TOC) analysis was utilized for surveying the mineralization of PEN G. In addition, based on Arrhenius equation, the activation energy of PEN G decomposition was calculated. The results indicated that the maximum PEN G removal rate was obtained at pH 5 and by increasing the doses of SPS from 0.05 to 0.5 mM, the PEN G decomposition was enhanced. It was found that an increase in temperature is accompanied by an increase in removal efficiency of PEN G. The activation energy of the studied process was determined to be 94.8 kJ mol-1, suggesting that a moderate activation energy is required for PEN G decomposition. The TOC measurements indicate that the HAP can efficiently mineralize PEN G. Besides, the presence of the scavengers significantly suppressed the HAP process to remove the PEN G. Overall, the results of this study demonstrate that using HAP process can be a suitable method for decomposing of PEN G in aqueous solutions. PMID- 29574210 TI - TAT-mediated intracellular delivery of carboxypeptidase G2 protects against methotrexate-induced cell death in HepG2 cells. AB - Side effects of methotrexate (MTX) especially hepatotoxicity limits clinical applications of this anticancer agent. Carboxypeptidase G2 (CPG2) is administrated for the treatment of elevated plasma concentrations of MTX. In this study, we have investigated the intracellular delivery of CPG2 fused to the transactivator transduction domain (TAT) and its protective effects against MTX induced cell death of HepG2 cells. We have observed that both native and denatured forms of the enzyme transduced into the HepG2 cells efficiently in a concentration and time-dependent manner. The denatured protein transduced with higher efficiency than the native form and was functional inside the cells. MTX exposure significantly decreased HepG2 cell viability in a dose- and time dependent manner. The cell viability after 24 and 48 h of incubation with 100 MUM MTX was reduced to 44.37% and 17.69%, respectively. In cells pretreated with native and denatured TAT-CPG2 protein the cell viability was 98.63% and 86.31% after 24 and 48 h, respectively. Treatment with MTX increased the number of apoptotic HepG2 cells to 90.23% after 48 h. However, the apoptosis percentage in cells pretreated with native and denatured TAT-CPG2 was 21.49% and 22.28%, respectively. Our results showed that TAT-CPG2 significantly prevents MTX-induced oxidative stress by decreasing the formation of ROS and increasing the content of glutathione (GSH) and catalase activity. Our finding indicates that both native and denatured TAT-CPG2 strongly protect HepG2 cells against MTX-induced oxidative stress and apoptosis. Hence, intracellular delivery of CPG2 might provide a new therapeutic strategy for protecting against MTX mediated cytotoxicity. PMID- 29574211 TI - EU decision-making for marketing authorization of advanced therapy medicinal products: a case study. AB - A comparative analysis of assessment procedures for authorization of all European Union (EU) applications for advanced therapy medicinal products (ATMPs) shows that negative opinions were associated with a lack of clinical efficacy and identified severe safety risks. Unmet medical need was often considered in positive opinions and outweighed scientific uncertainties. Numerous quality issues illustrate the difficulties in this domain for ATMP development. Altogether, it suggests that setting appropriate standards for ATMP authorization in Europe, similar to elsewhere, is a learning experience. The experimental characteristics of authorized ATMPs urge regulators, industry, and clinical practice to pay accurate attention to post-marketing risk management to limit patient risk. Methodologies for ATMP development and regulatory evaluations need to be continuously evaluated for the field to flourish. PMID- 29574212 TI - Computational modeling approaches to quantitative structure-binding kinetics relationships in drug discovery. AB - Simple comparative correlation analyses and quantitative structure-kinetics relationship (QSKR) models highlight the interplay of kinetic rates and binding affinity as an essential feature in drug design and discovery. The choice of the molecular series, and their structural variations, used in QSKR modeling is fundamental to understanding the mechanistic implications of ligand and/or drug target binding and/or unbinding processes. Here, we discuss the implications of linear correlations between kinetic rates and binding affinity constants and the relevance of the computational approaches to QSKR modeling. PMID- 29574213 TI - Strategic R&D transactions in personalized drug development. AB - Although external collaboration capability influences the development of personalized medicine, key transactions in the pharmaceutical industry have not been addressed. To explore specific trends in interorganizational transactions and key players, we longitudinally surveyed strategic transactions, comparing them with other advanced medical developments, such as antibody therapy, as controls. We found that the financing deals of start-ups have surged over the past decade, accelerating intellectual property (IP) creation. Our correlation and regression analyses identified determinants of financing deals among alliance deals, acquisition deals, patents, research and development (R&D) licenses, market licenses, and scientific papers. They showed that patents positively correlated with transactions, and that the number of R&D licenses significantly predicted financing deals. This indicates, for the first time, that start-ups and investors lead progress in personalized medicine. PMID- 29574214 TI - Mechanistic insights into functional characteristics of native crotamine. AB - The chemical composition of snake venoms is a complex mixture of proteins and peptides that can be pharmacologically active. Crotamine, a cell-penetrating peptide, has been described to have antimicrobial properties and it exerts its effects by interacting selectively with different structures, inducing changes in the ion flow pattern and cellular responses. However, its real therapeutic potential is not yet fully known. Bearing in mind that crotamine is a promising molecule in therapeutics, this study investigated the action of purified molecule in three aspects: I) antibacterial action on different species of clinical interest, II) the effect of two different concentrations of the molecule on platelet aggregation, and III) its effects on isolated mitochondria. Crotamine was purified to homogeneity in a single step procedure using Heparin Sepharose. The molecular mass of the purified enzyme was 4881.4 Da, as determined by mass spectrometry. To assess antibacterial action, changes in the parameters of bacterial oxidative stress were determined. The peptide showed antibacterial activity on Escherichia coli (MIC: 2.0 MUg/MUL), Staphylococcus aureus (MIC: 8-16 MUg/MUL) and methicillin-resistant Staphylococcus aureus (MIC: 4.0-8.0 MUg/MUL), inducing bacterial death by lipid peroxidation and oxidation of target proteins, determined by thiobarbituric acid reactive substances and sulfhydryl groups, respectively. Crotamine induced increased platelet aggregation (IPA) at the two concentrations analyzed (0.1 and 1.4 MUg/MUL) compared to ADP-induced aggregation of PRP. Mitochondrial respiratory parameters and organelle structure assays were used to elucidate the action of the compound in this organelle. The exposure of mitochondria to crotamine caused a decrease in oxidative phosphorylation and changes in mitochondrial permeability, without causing damage in the mitochondrial redox state. Together, these results support the hypothesis that, besides the antimicrobial potential, crotamine acts on different molecular targets, inducing platelet aggregation and mitochondrial dysfunction. PMID- 29574215 TI - Lactobacillus plantarum alleviate aflatoxins (B1 and M1) induced disturbances in the intestinal genes expression and DNA fragmentation in mice. AB - This study aimed to assess the disturbances in intestinal genes expression and DNA fragmentation in mice treated orally with aflatoxin B1 (AFB1) or aflatoxin M1 (AFM1) and the protective activity of Lactobacillus plantarum (LP). Male Balb/c mice were divided into 6 groups including the control group, the group treated with 2 mg/kg b.w of LP (2 * 109 cfu/mL), the groups treated with AFB1 or AFM1 (100 MUg/kg b.w), and the groups treated with AFB1 or AFM1 during, after or before LP. Small intestines were collected for the determination of DNA fragmentation, gene expression and target protein content. The results showed that AFB1 or AFM1 increased DNA fragmentation, down regulated the expressions of caspase-3, caspase-9, CYP3A13, Bax and p53 as well as up-regulated the expression of TNF-alpha and Bcl-2 and their target proteins. LP succeeded to alleviate the disturbances in DNA fragmentation and the expression of these genes. The improvement was more pronounced in the group co-administered with the toxins plus LP. It could be concluded that AFB1 and AFM1 induced disturbances in intestinal function via the disturbances in DNA fragmentation and genes expression. LP induced a potential protective effect and is considered a promising agent against the genotoxicity induced by these mycotoxins. PMID- 29574216 TI - Activity-based anorexia activates CRF immunoreactive neurons in female rats. AB - Activity-based anorexia (ABA) is a well-established animal model mimicking the eating disorder anorexia nervosa (AN). Since the pathophysiology of AN is yet poorly understood and specific drug treatments are lacking so far, animal models might be useful to further understand this disease. ABA consists of time restricted access to food for 1.5 h/day and the possibility to exercise in a running wheel for 24 h/day. This combination leads to robust body weight loss as observed in AN. Here, we investigated the activation of brain corticotropin releasing factor (CRF) neurons, a transmitter involved in the response to stress, emotional processes and also food intake. After development of ABA, rat brains were processed for c-Fos and CRF double immunohistochemistry. ABA increased the number of c-Fos/CRF double labeled neurons in the paraventricular nucleus (PVN) and the dorsomedial hypothalamic nucleus (DMH) compared to the ad libitum (AL, ad libitum fed, no running wheel) and activity (AC, ad libitum fed, running wheel, p < 0.05) but not to the restricted feeding (RF, food for 1.5 h/day, no running wheel, p > 0.05) group. Also the number of CRF neurons was increased in the DMH of ABA rats compared to AL and AC (p < 0.05). In the Edinger-Westphal nucleus (EW) the number of c-Fos positive neurons was increased in ABA and RF compared to AC (p < 0.05), while the number of double labeled neurons was not different (p > 0.05). Taken together, brain CRF activated under conditions of ABA might play a role in the development and maintenance of this animal model and possibly also in human AN. PMID- 29574217 TI - The impact of ALDH2 activation by Alda-1 on the expression of VEGF in the hippocampus of a rat model of post-MI depression. AB - Post-MI depression is a critical clinical problem, the comorbidity of which complicates depression treatment and worsens cardiovascular outcomes. However, which antidepressant is the best to lower the risk of cardiovascular events in persons with depression was still unknown. Recently, it has been proposed that the activation of ALDH2 by Alda-1 can effectively reduce depressive-like behaviors and improve the prognosis of coronary heart disease. In the present study, we investigated the effect of Alda-1 on the expression of VEGF in the hippocampus of a rat model with post-MI depression, as well as the potential treatment mechanism. Alda-1 administration significantly decreased the immobility time and increased the swimming time of the post-MI depression rats in the forced swim test. Moreover, treatment of post-MI depression rats with Alda-1 significantly increased the sucrose preference ratio, as assessed by a sucrose preference test. These behaviors were associated with an increase 5-HT and DA neurotransmitter content, as well as an increase of VEGF levels in the hippocampus of the post-MI depression rats. These results suggest that Alda-1 improves depressive-like behavior in rats after MI by increasing VEGF expression in the hippocampus of rats. PMID- 29574218 TI - Central irisin administration suppresses thyroid hormone production but increases energy consumption in rats. AB - Irisin, which is secreted from the skeletal muscle in response to physical exercise and defined as a thermogenic peptide, may play an important role in energy metabolism. Thyroid hormones, which are one of the other influential factors on the metabolic status, increase heat production and are the main regulators of energy metabolism. This study was conducted to determine the possible effects of irisin administration on thyroid hormones. Forty adult male Wistar albino rats were used in the study. The rats were equally divided into 4 groups (n = 10). The brain infusion kit was implanted in the groups, and irisin (or solvent as control) was centrally administered to the rats via osmotic mini pumps for 7 days. During the experiment, food consumption, body weights, and body temperatures of the animals were recorded. Food intake was significantly increased in the groups treated with irisin (p < 0.05), but their body weights were not changed. Hypothalamic TRH gene expression, serum TSH, fT3, and fT4 levels were significantly lower in the groups treated with irisin as compared to the naive and control groups (p < 0.05). In addition, irisin increased UCP1 mRNA expression in white and brown adipose tissue and UCP3 mRNA expression in muscle tissue in rats and also raised their body temperature (p < 0.05). Consequently, although central irisin administration has inhibitory effects on the hypothalamic pituitary-thyroid axis, it seems to be an important agent in the regulation of food intake and energy metabolism.

Cytoskeletal components, such as tubulins and actins, have the remarkable ability to organize themselves into filaments and networks to support specialized and compartmentalized functions. Alterations in cytoskeletal proteins have long been associated with a variety of neurodevelopmental disorders. This review focuses on recent findings, primarily from forward genetic screens in Caenorhabditis elegans that illustrate how different tubulin protein isotypes can play distinct roles in neuronal development and function. Additionally, we discuss studies revealing new regulators of the actin cytoskeleton, and highlight recent technological advances in in vivo imaging and functional dissection of the neuronal cytoskeleton. PMID- 29574220 TI - Long-Term Outcome of Nonfunctioning and Hormonal Active Pituitary Adenoma After Gamma Knife Radiosurgery. AB - INTRODUCTION: Stereotactic radiosurgery (SRS), particularly Gamma Knife radiosurgery (GKRS) is an established treatment option for residual and recurrent pituitary adenoma tumors. It helps in the preservation of surrounding normal neuronal, vascular, and hormone-producing structures and causes fewer neurologic deficits. The aim of this research was to evaluate the efficacy and define the role of GKRS in the treatment of nonfunctioning (NFA) and hormonal active (HAA) pituitary adenoma. METHODS: A retrospective analysis of 111 patients with histologically proven pituitary adenoma who underwent GKRS treatment at Louisiana State University Health Sciences Center, Shreveport, Louisiana, USA, over a 17 year period was conducted presented. The clinical and radiologic data were collected from the database. The tumors were categorized into NFA and HAA based on the endocrinology profile. The relevant statistical analysis was conducted with SPSS software, version 22.0. RESULTS: The median age of the patients was 58 years. The study comprised 87 patients with NFA and 24 patients with HAA tumors. Thirty-eight patients (34.2%) had hypopituitarism symptoms, and 8 patients (7%) had panhypopituitarism symptoms. The mean tumor volume before to GKRS was 3.8 cm3. Suprasellar and cavernous extension of the tumor was noted in 28 patients (25.2%) and 34 (30.6%) patients, respectively. We observed >70% reduction in the size of tumors in the shrinkage cohort after GKRS; the median time for shrinkage was 48.4 months. However, increase in tumor size was noted in the progression cohort (pre-GKRS 3.8 cm3 vs. post-GKRS 6.5 cm3). Seventy patients (63.1%) had neurologic improvement, and 26 patients (23.4%) had endocrinologic worsening after GKRS. CONCLUSIONS: GKRS plays a significant role in the treatment of NFA and HAA. It affords a high rate of tumor control and offers a low risk of collateral neurologic or endocrine axis injury. Our study shows that control of tumor growth was achieved in 90% of patients, shrinkage of tumor in 54%, and arrest of progression in 36% after GKRS treatment. The biochemical remission rate in growth hormone secreting adenoma was 57%, in adrenocorticotropic hormone adenoma 67%, and prolactinoma 40%. Age below 50 years and tumor volume less than 5 cm3 were associated with a favorable radiosurgical outcome. PMID- 29574221 TI - Endoscopic Endonasal Clipping of Anterior Circulation Aneurysm: Surgical Techniques and Results. AB - BACKGROUND: Endoscopic endonasal clipping of intracranial aneurysms may use microsurgical techniques as an alternative to the transcranial approach. Here we report a series of patients who underwent microsurgical clipping of anterior circulation aneurysms via an endoscopic endonasal approach (EEA). METHODS: This retrospective chart review included all the patients who underwent standard binostril EEA for aneurysm clipping. Surgical outcomes and complications are noted. The rationality and limitations of this procedure are discussed. RESULTS: Seven patients with 12 aneurysms of the anterior circulation underwent EEA for clipping. These 12 aneurysms consisted of 5 anterior communicating artery (AComA) aneurysms, 4 paraclinoid aneurysms, 1 ophthalmic artery aneurysm, and 2 aneurysm located in the cavernous segment of internal carotid artery (ICA). Nine of the 12 aneurysms were successfully clipped. One giant paraclinoid aneurysm could not be clipped during operation and was coiled in second endovascular stage. The 2 aneurysms located in the cavernous segment of ICA were not clipped intentionally in a single-stage procedure, after weighing the surgical benefit against the difficulty of surgical exposure and feasibility. The proximal control of ICA was achieved in all cases. There was no death, no cerebrospinal fluid leak, or other complications. All patients recovered completely. CONCLUSIONS: EEA can provide direct access for microsurgical clipping of strictly selected anterior circulation aneurysms. All the principles of cerebrovascular surgery must be followed. These procedures require a long learning curve. Only teams with adequate experience in microvascular and endoscopic skull base surgeries should attempt this approach for treating aneurysms. PMID- 29574222 TI - The Dilemma of Anticoagulating Patients with Cerebral Venous Thrombosis Who Underwent Decompressive Craniectomy. AB - BACKGROUND: Cerebral venous thrombosis is an uncommon subtype of cerebrovascular accident. The appropriate time interval between decompressive craniectomy and the onset of anticoagulation in patients with cerebral venous thrombosis is a controversial topic among neurosurgeons, neurologists, and intensivists. CASE DESCRIPTION: We present a brief clinical case report of a female patient who underwent decompressive craniectomy. Cerebral venous thrombosis was subsequently diagnosed, and anticoagulation was initiated 24 hours postoperatively. CONCLUSIONS: Early onset of anticoagulation is important for a favorable outcome. Clinical decision making should rely on the following: 1) postoperative imaging studies with no evidence of increase in hematoma, 2) intracranial pressure monitoring for patients on mechanical ventilation, and 3) protocols for immediate suspension of anticoagulants and use of antagonistic drugs in case of an increase in a pre-existing intracranial hemorrhage. PMID- 29574223 TI - Spinal Sclerosing Epithelioid Fibrosarcoma at the Cervicothoracic Junction. AB - BACKGROUND: Sclerosing epithelioid fibrosarcoma (SEF) is an unusual variant of fibrosarcoma that was previously considered to be a low-grade tumor with an indolent course. To our knowledge, the spine is a rare primary site for SEF, with only a few cases reported to date. CASE DESCRIPTION: We report a case of SEF occurring in the cervicothoracic spine of a 64-year-old man with complaints of neck pain and right hand tingling for 6 months before clinical presentation. Imaging revealed a large mass that extended from C5 to T1 in the right posterior paraspinal soft tissues, with involvement of the posterior elements from C6 to T1 and infiltration of the T1 vertebral body. We performed an en bloc spondylectomy and gross total resection of the tumor. Pathologic and immunohistochemical characteristics confirmed the diagnosis of SEF. CONCLUSIONS: Because of the anatomic nature of the cervicothoracic spine and critical neurovascular structures that the tumor involves, a true en bloc resection might not be possible, but an oncologically sound excision is ideal. PMID- 29574224 TI - The Incidence and Impact of Secondary Cerebral Insults on Outcome After Aneurysmal Subarachnoid Hemorrhage. AB - INTRODUCTION: Secondary cerebral insults can adversely affect patients with traumatic brain injury. By contrast, the incidence of secondary cerebral insults after aneurysmal subarachnoid hemorrhage (SAH) and their impact on outcome have been less well studied. METHODS: Four hundred and twenty-one patients with SAH who underwent surgical occlusion of their ruptured aneurysm and who received intensive care unit care for >=48 hours were retrospectively identified from a prospective observational database. Patients were managed according to standard recommendations for SAH. Three secondary cerebral insults were examined: hypotension (<90 mmHg systolic), hypoxia (Pao2 <60 mm Hg), and hyperglycemia (>200 mg/dL). RESULTS: A secondary cerebral insult was observed in 309 (73.4%) patients including 135 (32.1%) who had multiple insults. There was an association between worse clinical grade and development of secondary insults (P = 0.0002), particularly multiple insults (P < 0.0001). When stratified by clinical grade, single (adjusted odds ratio [OR], 2.23; 95% confidence interval [CI], 1.10-4.51; P = 0.026) and multiple (adjusted OR, 4.37; 95% CI, 2.14-8.93; P < 0.0001) secondary cerebral insults were associated with worse outcome. In multivariate analysis and controlling for age, admission clinical grade, severity of SAH on computed tomography, intracerebral hematoma, increased intracranial pressure (>20 mm Hg), rebleed, intraoperative rupture, and hydrocephalus, secondary cerebral insults were independently associated with poor outcome (adjusted OR, 2.45; 95% CI, 1.20-5.02; P = 0.014). CONCLUSIONS: Secondary cerebral insults (hypoxia, hypotension, and hyperglycemia) are common after SAH, including among patients with a good clinical grade. These insults after SAH are associated with worse outcome. These data suggest that prevention of secondary cerebral insults may provide an opportunity to improve patient outcome after SAH. PMID- 29574225 TI - Dioscin alleviates non-alcoholic fatty liver disease through adjusting lipid metabolism via SIRT1/AMPK signaling pathway. AB - Dioscin, one natural product, has active effect against non-alcoholic fatty liver disease (NAFLD) in our previous work. However, the pharmacological data are insufficient and the mechanisms have not been reported. Thus, this study aims to comprehensively investigate the effects and molecular mechanisms of dioscin against NAFLD. The primary cultured hepatocytes, AML-12 and HepG-2 cells were treated with palmic acid (PA) after dioscin treatment. The mice and rats were induced by high fat diet to establish the in vivo models of NAFLD. Dioscin obviously alleviated liver lipid accumulation symptoms and improved the levels of serum and hepatic biochemical parameters in vitro and in vivo. Further investigations revealed that dioscin significantly attenuated lipid metabolism via adjusting SIRT1/AMPK signal pathway to regulate the expression levels of SREBP-1c, CPT, FAS, SCD, FoxO1 and ATGL. In addition, suppression of SIRT1 by Nicotinamide or abrogation of AMPK by Compound C eliminated the inhibitory effects of dioscin on lipid metabolism. Therefore, our findings further demonstrated that dioscin markedly prevented NAFLD through adjusting lipid metabolism via SIRT1/AMPK signal pathway, which should be developed as a new candidate for NAFLD. PMID- 29574226 TI - Role of ASIC1a in Abeta-induced synaptic alterations in the hippocampus. AB - Acid-sensing ion channels (ASICs) are widely expressed in the mammalian central nervous system where they play a key role in synaptic transmission and in specific forms of memory. On the other hand, ASICs can be persistently active under pathological conditions contributing to neuronal damage in ischemic stroke, brain trauma, epilepsy and Parkinson's disease. However, to date no experimental evidence has linked ASICs to Alzheimer's disease (AD). Aim of the present work was to investigate, in CA1 pyramidal neurons, the possible involvement of ASIC1a in the Abeta-mediated effect on metabotropic glutamate (mGlu) receptor dependent transmission. We found that, in slices pretreated with Abeta, the pharmacological blockade of ASIC1a restored the increased intrinsic excitability following group I mGlu receptor activation. This suggests that, under certain conditions, ASIC1a might further contribute to the Abeta-related depolarizing response. We have recently demonstrated that ASIC1a is also involved long-term depression (LTD) induced either by low-frequency stimulation or by application of the group I mGlu receptor agonist DHPG. Here, we have shown that psalmotoxin-1, a selective blocker of ASIC1a, rescued the DHPG-LTD facilitation associated with genetic and non-genetic models of AD. Overall, these results suggest that a functional coupling between ASIC1a and mGlu receptors occurs and might contribute to the synaptic alterations associated with AD. PMID- 29574227 TI - mTOR signaling in the nucleus accumbens mediates behavioral sensitization to methamphetamine. AB - Chronic psychostimulant treatment in rodents readily produces behavioral sensitization, which reflects altered brain function in response to repeated drug exposure. Numerous morphological and biochemical investigations implicate altered neural plasticity in striatal medium spiny neurons (MSNs) as an essential component in behavioral sensitization. The mammalian target of the rapamycin (mTOR) signaling pathway, a key regulator of synaptic neuroplasticity, in the ventral striatum of methamphetamine (METH) -sensitized mice was investigated to determine if a link exists with the development of METH sensitization. Behaviorally, METH-sensitized mice possessed increased levels of phosphorylated mTOR/S2448 and its down-stream regulator p70S6K and pS6 in the ventral striatum. Systemic treatment with rapamycin, a specific mTOR inhibitor, coincident with a daily METH injection suppressed the induction of METH sensitization and reduced the number of dendritic spines in the shell and core of the nucleus accumbens. The infusion of lentivirus-expressing mTOR-shRNA into the shell region of the nucleus accumbens inhibited the induction of behavioral sensitization to METH, which was comparable to the effect of rapamycin. These results suggest that mTORC1-mediated signaling in the nucleus accumbens mediates the development of behavioral sensitization to METH. PMID- 29574228 TI - A Platform for Preparing Homogeneous Proteinaceous Subvisible Particles With Distinct Morphologies. AB - Regulatory authorities and scientific communities are increasingly attentive to the known and universal presence of small particulates in biological drug products. The underlying concern is that these particulates may cause unwanted formation of antidrug antibodies in patients. Pharmacological studies, however, have to date not succeeded in unambiguously identifying risk-prone particle properties. This lack of success may be partly due to a lack of available, well defined, homogenous particle material. Protein particles arising from stress of protein drug products are by nature often highly heterogeneous in size, morphology, and structure of the constituent protein in the particles. Here, we present simple and pharmaceutically relevant stress conditions to produce 8 different highly homogenous micrometer-sized protein particles from human insulin, representing very different morphologies and conformation of the constituent protein molecules in the particles generated. Insulin's self association patterns were varied by formulation approaches to create diverse starting materials. The resulting collection of homogenous particles underlines that the particle formation is not necessarily a random process but a consequence of formulation and specific stress condition. Owing to the inherent homogenicity of these populations, the particle materials can act as a standard platform for further studies on insulin subvisible particles in drug products. PMID- 29574229 TI - Simple and Robust N-Glycan Analysis Based on Improved 2-Aminobenzoic Acid Labeling for Recombinant Therapeutic Glycoproteins. AB - N-glycans of therapeutic glycoproteins are critical quality attributes that should be monitored throughout all stages of biopharmaceutical development. To reduce both the time for sample preparation and the variations in analytical results, we have developed an N-glycan analysis method that includes improved 2 aminobenzoic acid (2-AA) labeling to easily remove deglycosylated proteins. Using this analytical method, 15 major 2-AA-labeled N-glycans of Enbrel(r) were separated into single peaks in hydrophilic interaction chromatography mode and therefore could be quantitated. 2-AA-labeled N-glycans were also highly compatible with in-line quadrupole time-of-flight mass spectrometry (MS) for structural identification. The structures of 15 major and 18 minor N-glycans were identified from their mass values determined by quadrupole time-of-flight MS. Furthermore, the structures of 14 major N-glycans were confirmed by interpreting the MS/MS data of each N-glycan. This analytical method was also successfully applied to neutral N-glycans of Humira(r) and highly sialylated N-glycans of NESP(r). Furthermore, the analysis data of Enbrel(r) that were accumulated for 2.5 years demonstrated the high-level consistency of this analytical method. Taken together, the results show that a wide repertoire of N-glycans of therapeutic glycoproteins can be analyzed with high efficiency and consistency using the improved 2-AA labeling-based N-glycan analysis method. PMID- 29574230 TI - Exploring a Kinetic Model Approach in Biopharmaceutics: Estimating the Fraction Absorbed of Orally Administered Drugs in Humans. AB - Increasing costs of research and development in the pharmaceutical industry has necessitated a growing interest in the early prediction of human pharmacokinetics of drug candidates. Of growing interest is the need to understand oral absorption, the most common route of small molecule drug administration. The fraction of dose absorbed (%Fa) is considered a critical yet challenging parameter to predict. A kinetic model has been developed and tested to provide an early prediction of the fraction dose absorbed in humans. Unlike the traditional plug-flow model, this model assumes first-order kinetics to estimate the amount of drug present in the stomach and small intestine as a function of time and calculates the amount of drug released and absorbed during the transit. Other variables can be included in calculation as a function of time to better mimic the physiological condition with this approach. Absorption efficiency is assigned along with %Fa to give a quantitative estimate of the limiting factor for oral absorption. The model was tested with literature and in-house compounds. It was found that this model gives a good prediction of human %Fa with a correction coefficient (R2) of 0.8 and greater between predicted and reported %Fa for all compounds. PMID- 29574231 TI - Reduced pupil dilation during action preparation in schizophrenia. AB - Impairments in cognitive control-the ability to exert control over thoughts and actions and respond flexibly to the environment-are well-documented in schizophrenia. However, the degree to which experimental task performance reflects true cognitive control impairments or more general alterations in effort, arousal and/or task preparedness is unclear. Pupillary responses can provide insight into these latter factors, as the pupil dilates with degree of cognitive effort and response preparation. In the current study, 16 medicated outpatients with schizophrenia (SZP) and 18 healthy controls performed a task that measures the ability to reactively inhibit and modify a planned action-the double-step task. In this task, participants were required to make a saccade to a visual target. Infrequently, the target jumped to a new location and participants were instructed to rapidly inhibit and change their eye movement plan. Applying a race model of performance, we have previously shown that SZP require more time to inhibit a planned action. In the current analysis, we measured pupil dilation associated with task preparation and found that SZP had a shallower increase in pupil size prior to the onset of the trial. Additionally, reduced magnitude of the pupil response was associated with negative symptom severity in patients. Based on primate neurophysiology and cognitive neuroscience work, we suggest that this blunted pupillary response may reflect abnormalities in a general orienting response or reduced motivational significance of a cue signifying the onset of a preparatory period and that these abnormalities might share an autonomic basis with negative symptoms. PMID- 29574232 TI - Individual differences in self-reported reward-approach tendencies relate to resting-state and reward-task-based fMRI measures. AB - In this study, we investigated neural responses during resting-state and reward task-based fMRI and how these related to individual differences in self-reported reward sensitivity. Resting-state fMRI data were collected from 191 college students, and 60 of these individuals further finished a reward-related fMRI task. Self-reported reward-approach tendencies were assessed using the behavioral activation scale. Behavioral activation scale scores were positively correlated with brain activations in the striatum bilaterally during reward processing. During rest, behavioral activation scale scores were positively correlated with functional connectivity between the left and right striatum and with functional connectivity between the right striatum and right middle frontal gyrus. Positive correlations were found between task-based striatal activations and the functional connectivity between the left and right striatum at rest. These results suggest a relationship between striatal task-based reward-related activations and resting connectivity strengths that relate to individual differences in reward-approach tendencies. PMID- 29574234 TI - Reduced distractor interference during vagus nerve stimulation. AB - Suppressing irrelevant information in decision making is an essential everyday skill. We studied whether this ability could be improved in epileptic patients during vagus nerve stimulation (VNS). VNS is known to increase norepinephrine (NE) in the brain. NE is thought to improve several aspects of cognitive control, including the suppression of irrelevant information. Nineteen epileptic VNS patients executed the Eriksen flanker task twice, both during on and off stimulation. Distractor interference was indexed by the congruency effect, a standard empirical marker of cognitive control. We found a reduced congruency effect during stimulation, which indicates an improved ability to suppress distractor interference. This effect was only found in patients that are clinically determined VNS-responders (n = 10). As VNS increases NE in VNS responders, our finding suggests a beneficial role of NE in cognitive control. At the same time, it suggests that VNS does not only reduce seizure frequency in epileptic patients, but also improves cognitive control. PMID- 29574233 TI - Independent contributions of theta and delta time-frequency activity to the visual oddball P3b. AB - A growing body of work suggests that the P300 (P3) event-related potential (ERP) component is better understood as a mixture of task-relevant processes (Polich, 2007). This converges with earlier time-frequency work suggesting that the P3b is primarily composed of centroparietal delta (0.5-3 Hz) and frontocentral theta (3 7 Hz) activity. Within this study (N = 229), we hope to re-affirm these prior ideas and expand upon them in several crucial ways, reassessing how delta and theta contribute to the visual oddball P3b through the lens of several recent decades of additional P3b research. We provide a comprehensive assessment of how theta and delta time-frequency activity contribute to several common variants of the time-domain P3b, specifically measuring the target and non-target P3b, as well as differences between targets and non-targets, target-to-target interval (TTI), and target habituation. Results replicate and extend earlier work indicating that delta and theta account for a majority of variance in both the target and non-target P3b as well as their respective amplitude differences. They also newly indicate that theta and delta activity can have unique contributions to TTI differences and target habituation effects. Results in target habituation particularly demonstrate how time-frequency analyses can disentangle nuanced changes in P3b activity, shedding new light on these complicated phenomena. Findings suggest that delta and theta measures index separable processes occurring during the P3b, and provide additional support for the idea that they index theoretical frontocentral and centroparietal P3 subcomponents. PMID- 29574235 TI - Just rewards: 17-Month-old infants expect agents to take resources according to the principles of distributive justice. AB - Adults expect distributive justice-that rewards are distributed according to the principles of equality and equity. Previous research has demonstrated that preschool-aged children are sensitive to distributive justice, yet the age at which these sensitivities emerge remains unknown. The current research demonstrates that 17-month-old infants (N = 84) expect individuals to distribute shared resources based on the amount of work each partner contributed to attain the resources. These findings provide evidence that sensitivity to two principles of distributive justice, equity and equality, emerges much earlier than has previously been suggested. PMID- 29574236 TI - Equivalent auditory distraction in children and adults. AB - There is an ongoing debate about whether children have more problems ignoring auditory distractors than adults. This is an important empirical question with direct implications for theories making predictions about the development of selective attention. In two experiments, the disruptive effect of to-be-ignored speech on short-term memory performance of third graders, fourth graders, fifth graders, younger adults, and older adults was examined. Three auditory conditions were compared: (a) steady state sequences in which the same distractor was repeated, (b) changing state sequences in which different distractors were presented, and (c) auditory deviant sequences in which a deviant distractor was presented in a sequence of repeated distractors. According to the attentional resource view, children should exhibit larger disruption by changing and deviant sounds due to their poorer attentional control abilities compared with adults. The duplex-mechanism account proposes that the auditory deviant effect is under attentional control, whereas the changing state effect is not, and thus predicts that children should be more susceptible to auditory deviants than adults but equally disrupted by changing state sequences. According to the renewed view of age-related distraction, there should be no age differences in cross-modal auditory distraction because some of the irrelevant auditory information can be filtered out early in the processing stream. Children and adults were equally disrupted by changing and deviant speech sounds regardless of whether task difficulty was equated between age groups or not. These results are consistent with the renewed view of age-related distraction. PMID- 29574237 TI - Ethical considerations in the uptake of influenza vaccination by healthcare workers. AB - OBJECTIVES: The World Health Organization (WHO) recommends annual seasonal influenza vaccination of healthcare workers (HCWs). Under the current voluntary scheme in England, uptake of vaccine in this group remains well below the 75% target. A mandatory scheme may improve rates, but raises the ethical issue of imposed vaccination. However, the existing voluntary scheme could also potentially infringe autonomy if those not wanting to join feel pressured or coerced into vaccination. The aim of this study was to explore HCW views and experiences with the current influenza vaccination programme. STUDY DESIGN: Questionnaire survey. METHODS: Between March 2015 and April 2016, a total of 140 questionnaires were completed across seven HCW groups, with the demographic, vaccination and opinion data statistically analysed using the chi-squared test, Kruskal-Wallis test and Mann-Whitney U-test as appropriate. RESULTS: No staff group met the national influenza vaccination target of 75% and vaccination rates varied between HCW groups. All groups reported some degree of external pressure to be vaccinated and there were mixed views on the concept of mandatory vaccination, with a lack of certainty over the vaccine's efficacy and/or a lack of information the most common reasons for not supporting it. CONCLUSION: The current voluntary influenza vaccination scheme has a number of flaws. Improvements in the quality and availability of information provided to employees may help Trusts increase vaccination rates, or achieve acceptance of any proposed mandatory programme.

PMID- 29574239 TI - Anticancer potential of benzothiazolic derivative (E)-2-((2-(benzo[d]thiazol-2 yl)hydrazono)methyl)-4-nitrophenol against melanoma cells. AB - Malignant melanoma is an important type of cancer worldwide due to its aggressiveness and poor survival rate. Significant efforts to understand the biology of melanoma and approaches to treat the advanced disease are focused on targeted gene inhibitors. Frequently mutated genes, such as NRAS, B-RAF and TP53, significantly exceed the frequency of mutations of other genes, emphasizing their importance for future targeted therapies. Considering the antitumor activity of benzothiazolic derivatives, this study aimed to demonstrate the action of benzothiazolic (E)-2-((2-(benzo[d]thiazol-2-yl)hydrazono)methyl)-4-nitrophenol (AFN01) against three established human melanoma cell lines that recapitulate the molecular landscape of the disease in terms of its genetic alterations and mutations, such as the TP53, NRAS and B-RAF genes. The results presented here indicate that AFN01, as a significant cytostatic and cytotoxic drug due to its induction of DNA fragmentation, causes single and double DNA strand breaks, consequently inhibiting cell proliferation, migration and invasion by promoting apoptosis. Our data suggest that AFN01 might be considered as a future therapeutic option for managing melanoma. PMID- 29574240 TI - Heterocyclic organobismuth (III) compounds containing an eight-membered ring: Inhibitory effects on cell cycle progression. AB - We previously showed that heterocyclic organobismuth compounds have excellent antimicrobial and antitumor potential. These compounds structurally consist of either six- or eight-membered rings. Previous research has shown that bi chlorodibenzo[c,f][1,5]thiabismocine (Compound 3), an eight-membered ring, induced G2/M arrest via inhibition of tubulin polymerization in HeLa cells. Additionally, N-tert-butyl-bi-chlorodi-benzo[c,f][1,5]azabismocine (Compound 1), another eight-membered ring, exhibited higher cytotoxicity than Compound 3 against several cancer cell lines, including HeLa and K562. Finally, bi chlorophenothiabismin-S,S-dioxide (Compound 5), a six-membered ring, exhibited lower antitumor activity than eight-membered ring compounds. In this study, we investigated the antimitotic activity of Compounds 1 and 5 in HeLa cells. At low concentrations, (0.1 and 0.25 MUM), Compound 1 inhibited cell growth and arrested the cell cycle in mitosis. However, 0.5 MUM Compound 1 exhibited no antimitotic activity. Conversely, Compound 5 weakly inhibited cell growth and did not markedly arrest the cell cycle. Flow cytometry showed that Compound 1 arrested the cell cycle at G2/M, resulting in apoptosis. Compound 1 inhibited tubulin polymerization as revealed by a cell-free assay, and both Compounds 1 and 3 inhibited microtubule spindle formation and chromosome alignment during prometaphase. These results suggest that eight-membered ring-containing organobismuth compounds can induce mitotic arrest by perturbing spindle dynamics. PMID- 29574241 TI - Acute disseminated encephalomyelitis, a rare post-malaria neurological complication: Case report and review of the literature. AB - There are four neurological complications that can occur after malaria treatment at a time when the patient is aparasitaemic: delayed cerebellar ataxia, acute inflammatory demyelinating polyneuropathy, post-malaria neurological syndrome and acute disseminated encephalomyelitis (ADEM). The authors describe a case of a 54 year-old male who presented with encephalopathy and generalized seizures forty three days after complete recovery from acute malaria by Plasmodium falciparum. Diagnosis of post-malaria ADEM was made based on the acute onset of the neurological symptoms, characteristic findings in magnetic resonance imaging of the brain and prompt response to steroid therapy. ADEM is an autoimmune demyelinating disease of the central nervous system that usually arises after an infection or vaccination. Its occurrence after malaria infection is relatively rare, and to the best of our knowledge there are only thirteen cases described in the literature. PMID- 29574242 TI - Comparative analysis of core genome MLST and SNP typing within a European Salmonella serovar Enteritidis outbreak. AB - Multi-country outbreaks of foodborne bacterial disease present challenges in their detection, tracking, and notification. As food is increasingly distributed across borders, such outbreaks are becoming more common. This increases the need for high-resolution, accessible, and replicable isolate typing schemes. Here we evaluate a core genome multilocus typing (cgMLST) scheme for the high-resolution reproducible typing of Salmonella enterica (S. enterica) isolates, by its application to a large European outbreak of S. enterica serovar Enteritidis. This outbreak had been extensively characterised using single nucleotide polymorphism (SNP)-based approaches. The cgMLST analysis was congruent with the original SNP based analysis, the epidemiological data, and whole genome MLST (wgMLST) analysis. Combination of the cgMLST and epidemiological data confirmed that the genetic diversity among the isolates predated the outbreak, and was likely present at the infection source. There was consequently no link between country of isolation and genetic diversity, but the cgMLST clusters were congruent with date of isolation. Furthermore, comparison with publicly available Enteritidis isolate data demonstrated that the cgMLST scheme presented is highly scalable, enabling outbreaks to be contextualised within the Salmonella genus. The cgMLST scheme is therefore shown to be a standardised and scalable typing method, which allows Salmonella outbreaks to be analysed and compared across laboratories and jurisdictions. PMID- 29574243 TI - A comparison of the performance of natural hybrids Saccharomyces cerevisiae * Saccharomyces kudriavzevii at low temperatures reveals the crucial role of their S. kudriavzevii genomic contribution. AB - Fermentation performance at low temperature is a common approach to obtain wines with better aroma, and is critical in industrial applications. Natural hybrids S. cerevisiae * S. kudriavzevii, isolated from fermentations in cold-climate European countries, have provided an understanding of the mechanisms of adaptation to grow at low temperature. In this work, we studied the performance of 23 S. cerevisiae * S. kudriavzevii hybrids at low temperature (8, 12 and 24 degrees C) to characterize their phenotypes. Kinetic parameters and spot tests revealed a different ability to grow at low temperature. Interestingly, the genome content of the S. kudriavzevii in hybrids was moderately correlated with a shorter lag phase, and the genetic origin of hybrids influenced their performance at low temperature (8 degrees C). The parental expression of cold marker genes (NSR1, GUT2 and GPD1) showed that the relative expression of the S. kudriavzevii alleles was higher than the expression of the S. cerevisiae alleles in hybrids with a better growth at low-temperatures. These results suggest that the genomic contribution of S. kudriavzevii to hybrids is important for improving the fitness of these strains at low temperature. PMID- 29574244 TI - Alpha-momorcharin enhances Tobacco mosaic virus resistance in tobaccoNN by manipulating jasmonic acid-salicylic acid crosstalk. AB - Alpha-momorcharin (alpha-MMC) is a type-I ribosome inactivating protein (RIP) with a molecular weight of 29 kDa found in plants. This protein has been shown to be effective against a broad range of human viruses and also has anti-tumor activities. However, the mechanism by which alpha-MMC induces plant defense responses and regulates the N gene to promote resistance to the Tobacco mosaic virus (TMV) is still not clear. By using pharmacological and infection experiments, we found that alpha-MMC enhances TMV resistance of tobacco plants containing the N gene (tobaccoNN). Our results showed that plants pretreated with 0.5 mg/ml alpha-MMC could relieve TMV-induced oxidative damage, had enhanced the expression of the N gene and increased biosynthesis of jasmonic acid (JA) and salicylic acid (SA). Moreover, transcription of JA and SA signaling pathway genes were increased, and their expression persisted for a longer period of time in plants pretreated with alpha-MMC compared with those pretreated with water. Importantly, exogenous application of 1-Aminobenzotriazole (ABT, SA inhibitor) and ibuprofen (JA inhibitor) reduced alpha-MMC induced plant resistance under viral infection. Thus, our results revealed that alpha-MMC enhances TMV resistance of tobaccoNN plants by manipulating JA-SA crosstalk.

AB - We employed synchrotron infrared (IR) mapping to resolve forward osmosis (FO) membrane fouling in osmotic membrane bioreactor (OMBR). Synchrotron IR mapping offers a unique perspective to elucidate the fouling mechanisms and associated consequences in OMBR operation. We demonstrated the spatial distribution and relative intensity of carbohydrate and protein longitudinally along of the fouled FO membrane at the conclusion of OMBR operation. Both transmission and attenuated total reflection (ATR) modes were used to map the cross-section and surface of the fouled FO membrane. Micro X-ray computed tomography revealed patchy, "sand dune" features on the membrane surface at the conclusion of OMBR operation. Synchrotron IR-ATR mapping demonstrated that the development of membrane fouling layer in OMBR operation was initiated by polysaccharide-like carbohydrate, followed by layering with protein-like substance, resulting in a characteristic "sand-dune" three dimensional feature. Synchrotron FTIR mapping shed light on foulant occurrence and accumulation in the draw solution. Strong penetration of protein-like substance into membrane matrix was visualised, resulting the detection of protein adsorption in the region of membrane supporting layer. PMID- 29574246 TI - Cell proliferation influenced by matrix compliance of gelatin grafted poly(d,l Lactide) three dimensional scaffolds. AB - Surface and mechanical properties of the biomaterials are determinants of cellular responses. In our previous study, star-shaped poly(d,l-Lactide)-b gelatin (ss-pLG) was reported for possessing improved cellular adhesion and proliferation. Here, we extended our investigation to establish the cellular compatibility of gelatin-grafted PDLLA with respect to mechanical properties of biological tissues. In this view, linear PDLLA-b-gelatin (l-pLG) was synthesized and tissue-level compatibility of 1-pLG and ss-pLG against fibroblasts (L929), myoblasts (C2C12) and preosteoblasts (MG-63) was examined. The cell proliferation of C2C12 was significantly higher within l-pLG scaffolds, whereas L929 showed intensified growth within ss-pLG scaffolds. The difference in cell proliferation may be attributed to the varying mechanical properties of scaffolds; where the stiffness of l-pLG scaffolds was notably higher than ss-pLG scaffolds, most likely due to the variable levels of gelatin grafting on the backbone of PDLLA. Therefore, gelatin grafting can be used to modulate mechanical property of the scaffolds and this study reveals the significance of the matrix stiffness to produce the successful 3D scaffolds for tissue engineering applications. PMID- 29574247 TI - Comparison of intra-articular hyaluronic acid and methylprednisolone for pain management in knee osteoarthritis: A meta-analysis of randomized controlled trials. AB - OBJECTIVE: We performed a meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of intra-articular methylprednisolone and hyaluronic acid (HA) in term of pain reduction and improvements of knee function in patients with knee osteoarthritis (OA). MATERIALS AND METHODS: The PubMed, EMBASE, ScienceDirect, and Cochrane Library databases were systematically searched for literature up to January 2018. RCTs involving HA and methylprednisolone in knee OA were included. Two independent reviewers performed independent data abstraction. The I2 statistic was used to assess heterogeneity. A fixed or random effects model was adopted for meta-analysis. All meta-analyses were performed by using STATA 14.0. RESULTS: Five RCTs with 1004 patients were included in the meta-analysis. The present meta-analysis indicated that there were no significant differences in terms of WOMAC pain, physical function and stiffness at 4 week, 12 weeks and 26 weeks between HA and methylprednisolone groups. No increased risk of adverse events were identified in both groups. CONCLUSION: Both HA and methylprednisolone injections were effective therapies for patients with knee OA. Methylprednisolone showed comparable efficacy in reducing pain and improving functional recovery to HA. And no significant difference was found in long-term of follow-up in terms of adverse effects. PMID- 29574248 TI - Embryonic-only arsenic exposure alters skeletal muscle satellite cell function in killifish (Fundulus heteroclitus). AB - Arsenic is a contaminant found worldwide in drinking water and food. Epidemiological studies have correlated arsenic exposure with reduced weight gain and improper muscular development, while in vitro studies show that arsenic exposure impairs myogenic differentiation. The purpose of this study was to use Fundulus heteroclitus or killifish as a model organism to determine if embryonic only arsenic exposure permanently reduces the number or function of muscle satellite cells. Killifish embryos were exposed to 0, 50, 200, or 800 ppb arsenite (AsIII) until hatching, and then juvenile fish were raised in clean water. At 28, 40, and 52 weeks after hatching, skeletal muscle injuries were induced by injecting cardiotoxin into the trunk of the fish just posterior to the dorsal fin. Muscle sections were collected at 0, 3 and 10 days post-injury. Collagen levels were used to assess muscle tissue damage and recovery, while levels of proliferating cell nuclear antigen (PCNA) and myogenin were quantified to compare proliferating cells and newly formed myoblasts. At 28 weeks of age, baseline collagen levels were 105% and 112% greater in 200 and 800 ppb groups, respectively, and at 52 weeks of age, were 58% higher than controls in the 200 ppb fish. After cardiotoxin injury, collagen levels tend to increase to a greater extent and take longer to resolve in the arsenic exposed fish. The number of baseline PCNA(+) cells were 48-216% greater in 800 ppb exposed fish compared to controls, depending on the week examined. However, following cardiotoxin injury, PCNA is reduced at 28 weeks in 200 and 800 ppb fish at day 3 during the recovery period. By 52 weeks, there are significant reductions in PCNA in all exposure groups at day 3 of the recovery period. Based on these results, embryonic arsenic exposure increases baseline collagen levels and PCNA(+) cells in skeletal muscle. However, when these fish are challenged with a muscle injury, the proliferation and differentiation of satellite cells into myogenic precursors is impaired and instead, the fish appear to be favoring a fibrotic resolution to the injury. PMID- 29574249 TI - Nanostructured silver fabric as a free-standing NanoZyme for colorimetric detection of glucose in urine. AB - Enzyme-mimicking catalytic nanoparticles, more commonly known as NanoZymes, have been at the forefront for the development of new sensing platforms for the detection of a range of molecules. Although solution-based NanoZymes have shown promise in glucose detection, the ability to immobilize NanoZymes on highly absorbent surfaces, particularly on free-standing substrates that can be feasibly exposed and removed from the reaction medium, can offer significant benefits for a range of biosensing and catalysis applications. This work, for the first time, shows the ability of Ag nanoparticles embedded within the 3D matrix of a cotton fabric to act as a free-standing peroxidase-mimic NanoZyme for the rapid detection of glucose in complex biological fluids such as urine. The use of cotton fabric as a template not only allows high number of catalytically active sites to participate in the enzyme-mimic catalytic reaction, the absorbent property of the cotton fibres also helps in rapid absorption of biological molecules such as glucose during the sensing event. This, in turn, brings the target molecule of interest in close proximity of the NanoZyme catalyst enabling accurate detection of glucose in urine. Additionally, the ability to extract the free-standing cotton fabric-supported NanoZyme following the reaction overcomes the issue of potential interference from colloidal nanoparticles during the assay. Based on these unique characteristics, nanostructured silver fabrics offer remarkable promise for the detection of glucose and other biomolecules in complex biological and environmental fluids. PMID- 29574250 TI - A Pre-Clinical Assessment of the Pan-ERBB Inhibitor Dacomitinib in Pediatric and Adult Brain Tumors. AB - Glioblastoma in adults, and medulloblastoma and pineoblastoma that mainly affect children, are aggressive brain tumors. The survival for patients with glioblastoma remains dismal. While the cure rate for medulloblastoma exceeds 70%, this figure has stagnated over the past few decades and survivors still contend with significant long-term debilitating side effects. The prognosis for pineoblastoma is age-dependent, with little chance of a cure for children younger than three years. More effective molecularly targeted strategies are urgently required to treat these cancers. Hyper-activation of epidermal growth factor receptor (EGFR) signaling is characteristic of several different classes of human cancers, including a subset of glioblastoma and medulloblastoma. This has provided the impetus for the development of a suite of EGFR pathway blockers, including second generation irreversible inhibitors, such as dacomitinib. We have developed a comprehensive drug evaluation pipeline, including in vitro interaction analyses and orthotopic xenograft mouse models, to address the efficacy of drugs for brain tumor treatment, enabling the exclusion of potentially ineffective treatments and prioritization of truly beneficial novel treatments for clinical trial. We used this system to examine the effects of dacomitinib as a single agent, or in combination with conventional chemotherapeutics, on the growth of human adult and pediatric brain tumor cell lines. Dacomitinib inhibited EGFR or EGFRvIII activity in vitro in all three tumor types tested, and as a single agent induced a modest increase in survival time for mice bearing glioblastoma, which accurately predicted human clinical trial data. For pediatric medulloblastoma, dacomitinib blocked EGFR/HER signalling in orthotopic xenografts and extended median survival as a single agent, however was antagonistic when used in combination with standard frontline medulloblastoma chemotherapies. The findings caution against the use of dacomitinib for pediatric brain tumor clinical trials. PMID- 29574251 TI - Rituximab Treatment Prevents Lymphoma Onset in Gastric Cancer Patient-Derived Xenografts. AB - Patient-Derived Xenografts (PDXs), entailing implantation of cancer specimens in immunocompromised mice, are emerging as a valuable translational model that could help validate biologically relevant targets and assist the clinical development of novel therapeutic strategies for gastric cancer. More than 30% of PDXs generated from gastric carcinoma samples developed human B-cell lymphomas instead of gastric cancer. These lymphomas were monoclonal, Epstein Barr Virus (EBV) positive, originated tumorigenic cell cultures and displayed a mutational burden and an expression profile distinct from gastric adenocarcinomas. The ability of grafted samples to develop lymphomas did not correlate with patient outcome, nor with the histotype, the lymphocyte infiltration level, or the EBV status of the original gastric tumor, impeding from foreseeing lymphoma onset. Interestingly, lymphoma development was significantly more frequent when primary rather than metastatic samples were grafted. Notably, the development of such lympho proliferative disease could be prevented by a short rituximab treatment upon mice implant, without negatively affecting gastric carcinoma engraftment. Due to the high frequency of human lymphoma onset, our data show that a careful histologic analysis is mandatory when generating gastric cancer PDXs. Such care would avoid misleading results that could occur if testing of putative gastric cancer therapies is performed in lymphoma PDXs. We propose rituximab treatment of mice to prevent lymphoma development in PDX models, averting the loss of human-derived samples. PMID- 29574252 TI - Targeting Long Noncoding RNA HMMR-AS1 Suppresses and Radiosensitizes Glioblastoma. AB - Emergent evidences revealed that long noncoding RNAs (lncRNAs) participate in neoplastic progression. HMMR is an oncogene that is highly expressed in glioblastoma (GBM) and supports GBM growth. Whether lncRNAs regulate HMMR in GBM remains unknown. Herein, we identify that an HMMR antisense lncRNA, HMMR-AS1, is hyperexpressed in GBM cell lines and stabilizes HMMR mRNA. Knockdown of HMMR-AS1 reduces HMMR expression; inhibits cell migration, invasion, and mesenchymal phenotypes; and suppresses GBM cell growth both in vitro and in vivo. Moreover, knockdown of HMMR-AS1 radiosensitizes GBM by reducing DNA repair proteins ATM, RAD51, and BMI1. Our data demonstrate a mechanism of sense-antisense interference between HMMR and HMMR-AS1 in GBM and suggest that targeting HMMR-AS1 is a potential strategy for GBM treatment. PMID- 29574254 TI - Adverse pregnancy outcomes in women with changing patterns of exposure to the emissions of a municipal waste incinerator. AB - Municipal solid waste incinerators emissions contain pollutants that, despite their low concentration, might adversely affect reproductive health. In the present study, we examined rates of miscarriage and birth defects among women who resided or were employed in the vicinity of a municipal solid waste incinerator plant from 2003 to 2013. In 2009, a progressive shutdown of the old incineration lines and operation of a new line caused considerably higher atmospheric release of polycyclic aromatic hydrocarbons, particularly of dioxins, due to these irregular operating conditions, technological renovation, and increased capacity. We used dioxin emission levels, based on a dispersion model, to define exposure status of the residing population to air pollutants emitted by the waste incinerator. In women who resided in areas characterized by higher emission exposures compared with a referent area, the relative risk (RR) of miscarriage was 1.04 (95% confidence interval (CI) 0.80-1.32) based on 62 cases overall, with little evidence of a dose-response relation. RRs were similarly null for both 2003-2008 and 2010-2013 periods (RR 1.12 (95% CI 0.80-1.53) and 0.98 (95% CI 0.63 1.48), respectively). Concerning birth defects in the offspring of women residing in the exposed area, no evidence of increased risk emerged, since the prevalence ratio at birth was 0.64 (95% CI 0.29-1.26), with comparable results in the 2003 2008 and 2010-2013 period. Corresponding analyses carried out in municipal residents who worked in the exposed area confirmed these findings. We also did not detect abnormally high rates of miscarriage and birth defects in the exposed cohorts in the single year 2009. Overall, these results do not suggest an effect of exposure to the emissions of the municipal solid waste incinerator we investigated on two indicators of reproductive health. However, the limited statistical stability of the estimates and the absence of individual-based information on some potential confounders suggest caution in the interpretation of study findings. PMID- 29574256 TI - Residential mobility and childhood leukemia. AB - AIMS: Studies of environmental exposures and childhood leukemia studies do not usually account for residential mobility. Yet, in addition to being a potential risk factor, mobility can induce selection bias, confounding, or measurement error in such studies. Using data collected for California Powerline Study (CAPS), we attempt to disentangle the effect of mobility. METHODS: We analyzed data from a population-based case-control study of childhood leukemia using cases who were born in California and diagnosed between 1988 and 2008 and birth certificate controls. We used stratified logistic regression, case-only analysis, and propensity-score adjustments to assess predictors of residential mobility between birth and diagnosis, and account for potential confounding due to residential mobility. RESULTS: Children who moved tended to be older, lived in housing other than single-family homes, had younger mothers and fewer siblings, and were of lower socioeconomic status. Odds ratios for leukemia among non-movers living <50 meters (m) from a 200+ kilovolt line (OR: 1.62; 95% CI: 0.72-3.65) and for calculated fields >= 0.4 microTesla (OR: 1.71; 95% CI: 0.65-4.52) were slightly higher than previously reported overall results. Adjustments for propensity scores based on all variables predictive of mobility, including dwelling type, increased odds ratios for leukemia to 2.61 (95% CI: 1.76-3.86) for living < 50 m from a 200 + kilovolt line and to 1.98 (1.11-3.52) for calculated fields. Individual or propensity-score adjustments for all variables, except dwelling type, did not materially change the estimates of power line exposures on childhood leukemia. CONCLUSION: The residential mobility of childhood leukemia cases varied by several sociodemographic characteristics, but not by the distance to the nearest power line or calculated magnetic fields. Mobility appears to be an unlikely explanation for the associations observed between power lines exposure and childhood leukemia. PMID- 29574255 TI - Cerium dioxide (CeO2) nanoparticles decrease arsenite (As(III)) cytotoxicity to 16HBE14o- human bronchial epithelial cells. AB - The production and application of engineered nanoparticles (NPs) are increasing in demand with the rapid development of nanotechnology. However, there are concerns that some of these novel materials could lead to emerging environmental and health problems. Some NPs are able to facilitate the transport of contaminants into cells/organisms via a "Trojan Horse" effect which enhances the toxicity of the adsorbed materials. In this work, we evaluated the toxicity of arsenite (As(III)) adsorbed onto cerium dioxide (CeO2) NPs to human bronchial epithelial cells (16HBE14o-) using the xCELLigence real time cell analyzing system (RTCA). Application of 0.5 mg/L As(III) resulted in 81.3% reduction of cell index (CI, an RTCA measure of cell toxicity) over 48 h when compared to control cells exposed to medium lacking As(III). However, when the cells were exposed to 0.5 mg/L As(III) in the presence of CeO2 NPs (250 mg/L), the CI was only reduced by 12.9% compared to the control. The CeO2 NPs had a high capacity for As(III) adsorption (20.2 mg/g CeO2) in the bioassay medium, effectively reducing dissolved As(III) in the aqueous solution and resulting in reduced toxicity. Transmission electron microscopy was used to study the transport of CeO2 NPs into 16HBE14o- cells. NP uptake via engulfment was observed and the internalized NPs accumulated in vesicles. The results demonstrate that dissolved As(III) in the aqueous solution was the decisive factor controlling As(III) toxicity of 16HBE14o- cells, and that CeO2 NPs effectively reduced available As(III) through adsorption. These data emphasize the evaluation of mixtures when assaying toxicity. PMID- 29574253 TI - Probing the role of the vestibular system in motivation and reward-based attention. AB - The vestibular system has widespread connections in the central nervous system. Several activation loci following vestibular stimulations have been notably reported in deep, limbic areas that are otherwise difficult to reach and modulate in healthy subjects. Following preliminary evidence, suggesting that such stimulations might affect mood and affective processing, we wondered whether the vestibular system is also involved in motivation. Evolutionary accounts suggest that visuo-vestibular mismatches might have a role in preventing the search for and exploitation of goods that previously resulted in aversive reactions, as they would be a fine warning signal which follows the contact with or ingestion of noxious neurotoxins. The first question was thus whether vestibular stimulation alters sensitivity to reward. Secondly, we sought to assess whether attention is allocated in space differently when cued by highly motivational stimuli, and if this interplay is further modulated by the vestibular system. In order to evaluate both motivational and attentional assets, we administered a Posner-like cueing task to 30 healthy subjects concurrently receiving sham or galvanic vestibular stimulation (GVS; Left-Anodal and Right-Anodal configurations). The participants had to discriminate targets appearing in either exogenously cued or uncued locations (50% validity); cues predicted the amount of points (0, 2, or 10) and thus money that they could earn for a correct response. The results highlight a robust inhibition of return (IOR) (faster responses for invalidly cued targets) which was not modulated by different levels of reward or GVS. Across all stimulation sessions, rewards exerted a powerful beneficial effect over performance: reaction times were faster when rewards were at stake. However, this effect was largest in sham, but greatly reduced in GVS conditions, most notably with the Right-Anodal configuration. This is the first evidence for a decreased sensitivity to rewards causally induced by a perturbation of the vestibular system. While future studies will shed light on its neural underpinnings and clinical implications, here we argue that GVS could be a safe and promising way to enrich our understanding of reward processes and eventually tackle the management of patients with aberrant sensitivity to rewards. PMID- 29574257 TI - Mechanisms underlying weight status and healthcare avoidance in women: A study of weight stigma, body-related shame and guilt, and healthcare stress. AB - Studies show that women with high BMI are less likely than thinner women to seek healthcare. We aimed to determine the mechanisms linking women's weight status to their healthcare avoidance. Women (N = 313) were surveyed from a U.S. health panel database. We tested a theory-driven model containing multiple stigma and body-related constructs linking BMI to healthcare avoidance. The model had a good fit to the data. Higher BMI was related to greater experienced and internalized weight stigma, which were linked to greater body-related shame. Internalized weight stigma was also related to greater body-related guilt, which was associated with higher body-related shame. Body-related shame was associated with healthcare stress which ultimately contributed to healthcare avoidance. We discuss recommendations for a Weight Inclusive Approach to healthcare and the importance of enhancing education for health professionals in weight bias in order to increase appropriate use of preventive healthcare in higher weight women. PMID- 29574258 TI - Water relation, leaf gas exchange and chlorophyll a fluorescence imaging of soybean leaves infected with Colletotrichum truncatum. AB - Considering the potential of anthracnose to decrease soybean yield and the need to gain more information regarding its effect on soybean physiology, the present study performed an in-depth analysis of the photosynthetic performance of soybean leaflets challenged with Colletotrichum truncatum by combining chlorophyll a fluorescence images with gas-exchange measurements and photosynthetic pigment pools. There were no significant differences between non-inoculated and inoculated plants in leaf water potential, apparent hydraulic conductance, net CO2 assimilation rate, stomatal conductance to water vapor and transpiration rate. For internal CO2 concentration, significant difference between non inoculated and inoculated plants occurred only at 36 h after inoculation. Reductions in the values of the chlorophyll a fluorescence parameters [initial fluorescence (F0), maximal fluorescence (Fm), maximal photosystem II quantum yield (Fv/Fm), quantum yield of regulated energy dissipation (Y(NPQ))] and increases in effective PS II quantum yield (Y(II)), quantum yield of non regulated energy dissipation Y(NO) and photochemical quenching coefficient (qP) were noticed on the necrotic vein tissue in contrast to the surrounding leaf tissue. It appears that the impact of the infection by C. truncatum on the photosynthetic performance of the leaflets was minimal considering the preference of the fungus to colonize the veins. PMID- 29574259 TI - Dorsal root ganglia pulsed radiofrequency treatment alters the spinal immune environment. PMID- 29574260 TI - HLA typing using genome wide data reveals susceptibility types for infections in a psychiatric disease enriched sample. AB - BACKGROUND: The infections Toxoplasma gondii (T. gondii), cytomegalovirus, and Herpes Simplex Virus Type 1 (HSV1) are common persistent infections that have been associated with schizophrenia and bipolar disorder. The major histocompatibility complex (MHC, termed HLA in humans) region has been implicated in these infections and these mental illnesses. The interplay of MHC genetics, mental illness, and infection has not been systematically examined in previous research. METHODS: In a cohort of 1636 individuals, we used genome-wide association data to impute 7 HLA types (A, B, C, DRB1, DQA1, DQB1, DPB1), and combined this data with serology data for these infections. We used regression analysis to assess the association between HLA alleles, infections (individually and collectively), and mental disorder status (schizophrenia, bipolar disorder, controls). RESULTS: After Bonferroni correction for multiple comparisons, HLA C*07:01 was associated with increased HSV1 infection among mentally healthy controls (OR 3.4, p = 0.0007) but not in the schizophrenia or bipolar groups (P > 0.05). For the multiple infection outcome, HLA B* 38:01 and HLA C*12:03 were protective in the healthy controls (OR ~ 0.4) but did not have a statistically significant effect in the schizophrenia or bipolar groups. T. gondii had several nominally-significant positive associations, including the haplotypes HLA DRB*03:01 ~ HLA DQA*05:01 ~ HLA DQB*02:01 and HLA B*08:01 ~ HLA C*07:01. CONCLUSIONS: We identified HLA types that showed strong and significant associations with neurotropic infections. Since some of these associations depended on mental illness status, the engagement of HLA-related pathways may be altered in schizophrenia due to immunogenetic differences or exposure history. PMID- 29574261 TI - The expression of TRPV channels, prostaglandin E2 and pro-inflammatory cytokines during behavioural fever in fish. AB - A fever, or increased body temperature, is a symptom of inflammation, which is a complex defence reaction of the organism to pathogenic infections. After pathogens enter the body, immune cells secrete a number of agents, the functions of which stimulate the body to develop a functional immune and fever response. In mammals it is known that PGE2 is the principal mediator of fever. The extent to which PGE2 and other pro-inflammatory cytokines such as TNF-alpha, IL-6, or IL 1beta could be involved in the induction of behavioural fever in fish remains to be clarified. Several members of the transient receptor potential (TRP) family of ion channels have been implicated as transducers of thermal stimuli, including TRPV1 and TRPV2, which are activated by heat. Here we show that members of the TRP family, TRPV1 and TRPV4, may participate in the coordination of temperature sensing during the behavioural fever. To examine the behavioral fever mechanism in Salmo salar an infection with IPNV, infectious pancreatic necrosis virus, was carried out by an immersion challenge with 10 * 105 PFU/mL-1 of IPNV. Behavioural fever impacted upon the expression levels of both TRPV1 and TRPV4 mRNAs after the viral challenge and revealed a juxtaposed regulation of TRPV channels. Our results suggest that an increase in the mRNA abundance of TRPV1 is tightly correlated with a significant elevation in the expression of pro-inflammatory cytokines (IL-1beta, IL-6, TNF-alpha and PGE2) in the Pre-Optic Area (POA) and cytokine release in plasma. Together, these data indicate that the reduction of TRPV4 expression during behavioural fever may contribute to the onset of behavioural fever influencing movement toward higher water temperatures. Our data also suggest an effect of TRPV channels in the regulation of behavioural fever through activation of EP3 receptors in the central nervous system by PGE2 induced by plasma-borne cytokines. These results highlight for first time in mobile ectotherms the key role of pro-inflammatory cytokines and TRPV channels in behavioural fever that likely involves a complex integration of prostaglandin induction, cytokine recognition and temperature sensing. PMID- 29574262 TI - Enacted stigma and felt stigma experienced by adults who stutter. AB - PURPOSE: The aim of this study was to (1) document the experiences of enacted stigma (external stigma, experienced discrimination) and felt stigma (anticipation and expectation of discrimination or negative treatment by others) in adults who stutter, (2) investigate their relationships to each other, and (3) investigate their relationships to global mental health. METHOD: Participants were 324 adults who stutter recruited from clinicians and self-help group leaders in the United States. Participants completed an anonymous web survey consisting of measures of enacted stigma, felt stigma, and global mental health. Data analysis focused on obtaining descriptive statistics for enacted stigma and felt stigma, and performing correlational analysis between these variables, and also between these variables and global mental health. RESULTS: Most participants reported experiencing several different forms of social devaluation and negative treatment from other people at some point in their lives (i.e., enacted stigma), although they rarely experienced these events during the past year. Most participants agreed that they anticipate future stigmatizing experiences (i.e., felt stigma). Enacted stigma in the past year demonstrated a significant positive relationship to felt stigma. Both enacted stigma in the past year and felt stigma demonstrated significant negative relationships with global mental health. Enacted stigma in the past year and felt stigma were unique predictors of participants' global mental health. CONCLUSIONS: People who stutter experience discrimination and social devaluation, and they anticipate future stigmatizing experiences. Both of these types of stigma, enacted and felt, are associated with reduced mental health in adults who stutter. Assessment and therapy with adults who stutter should address these aspects of stuttering. PMID- 29574263 TI - Evaluation of joint effects of cyprodinil and kresoxim-methyl on zebrafish, Danio rerio. AB - Aquatic organisms are usually exposed to a mixture of pesticides instead of individual chemicals. However, risk assessment of pesticides is traditionally based on toxicity data of individual compounds. In this study, we aimed to examine the joint toxicity of two fungicides cyprodinil (CYP) and kresoxim-methyl (KRM) to zebrafish (Danio rerio) using a systematic experimental approach. Results from 96-h semi-static test indicated that the LC50 values of KRM to D. rerio at multiple life stages (embryonic, larval, juvenile and adult stages) ranged from 0.034 (0.015-0.073) to 0.61 (0.39-0.83) mg a.i. L-1, which were higher than those of CYP ranging from 1.05 (0.88-1.52) to 4.42 (3.24-6.02) mg a.i. L-1. Pesticide mixtures of CYP and KRM exhibited synergistic effect on embryonic zebrafish. The activities of carboxylesterase (CarE) and cytochrome P450 (Cyp450) were significantly altered in most of the individual and combined exposures compared with the control group. The expressions of seven genes (Mnsod, cyp17, crhr 2, crh, gnrhr 4, gnrhr 1 and hmgrb) were significantly altered upon exposure to combined pesticides compared with their individual pesticides. Collectively, these findings suggested joint effects should be considered in the risk assessment of pesticides and development of water quality criteria for the protection of aquatic environment. PMID- 29574264 TI - CO2 switchable hollow nanospheres. AB - HYPOTHESIS: Hollow nanospheres, characterized by a cavity inside a solid shell, have potential applications due to their unique structure, but the unchangeable morphology and permeability of the shell restrain their further practical utilization. While several smart hollow nanospheres that can respond to pH, ion strength, and temperature have been developed, they are inclined to suffer from problems associated with high energy consumption or the difficult removal of residual stimulants. Thus, it is desirable to develop a novel and free-of residual trigger stimulating mode. EXPERIMENTS: In this work, CO2 is used to fabricate smart hollow nanospheres composed of crosslinked poly(diethylamino ethyl methacrylate) (PDEAEMA) network from polystyrene (PS)/PDEAEMA core-shell nanospheres by a template-removal technique. The morphology evolution of the resultant nanospheres during the fabrication process was characterized by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), thermogravimetry analysis (TGA) and dynamic light scattering (DLS) and was visualized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). FINDINGS: Hollow nanospheres can be generated by experiencing a morphology change from a core nanosphere, core-shell, yolk-shell to a final hollow structure. The increase in shell-stiffness can restrain the collapse of hollow spheres. It is demonstrated that CO2 is easy to introduce and remove (via N2 input) without stimulation residues in this system. In addition, mild CO2/N2 purging can only reversibly change the swelling/collapse of hollow particles; violent CO2/N2 bubbling can reversibly regulate both the size and aggregation/re dispersion state of the hollow nanospheres, which can be intuitively observed by atomic force microscopy (AFM). PMID- 29574265 TI - Synthesis of raspberry-like polymer/SiO2 hybrid colloidal spheres grafted by block-copolymer poly(MPC-b-MPS) for underwater superoleophobic anti-biofouling coatings. AB - Raspberry-like polymer/inorganic compound hybrid colloidal spheres have attracted tremendous interest owing to their many potential applications, but most of them are concentrated on synthesis methods, controlling structures and morphologies. Herein, we synthesize raspberry-like poly(ethyl methacrylate)/SiO2 colloidal spheres and further graft a hydrophilic diblock copolymer on the SiO2 nanoparticles. The obtained copolymer-grafted hybrid sphere-based coatings are robust and display excellent underwater superoleophobic and anti-biofouling performances as well as self-repairing ability. PMID- 29574266 TI - Novel Ag-Cu bimetallic alloy decorated near-infrared responsive three-dimensional rod-like architectures for efficient photocatalytic water purification. AB - In this paper, novel silver-copper bimetallic alloy (Ag-Cu) nanoparticles (NPs) decorated beta-NaYF4: Yb3+, Tm3+@TiO2 ("@" means TiO2 supported on NaYF4: Yb3+, Tm3+, marked as NYFT) micro-rods were successfully synthesized through a surfactant-assistant sol-gel method and H2 reduction process for the first time. In NYFT@Ag-Cu composite, efficient energy transfer from beta-NaYF4: Yb3+, Tm3+ (NYF) to TiO2 and metal NPs was confirmed. Under near-infrared (NIR) light irradiation, Ag-Cu alloy supported NYFT exhibited significantly enhanced photocatalytic activity in comparison with other samples, and water disinfection involving 100% inactivation of bacteria was realized within 8 h. The strengthened photocatalytic activity was assigned to the synergistic effect of up-conversion (UC) material and alloy NPs. Some reasons for the improved photocatalytic activity were systematically investigated and a probable mechanism for NIR responsive photocatalysis was elucidated.

AB - A combination of electrospinning technique and hydrothermal process was carried out to fabricate zinc oxide nano-flakes wrapped carbon nanofibers (ZnO/CNFs) composite as an effective electrode material for supercapacitor. The morphology of the as-synthesized composite clearly revealed that the carbon nanofibers were successfully wrapped with ZnO nano-flakes. The electrochemical performance of the as-synthesized nanocomposite electrode was evaluated by the cyclic voltammetry (CV), galvanostatic charge-discharge (GDC), and electrochemical impedance spectroscopy (EIS), and compared with the pristine ZnO nanofibers. It was found that the composite exhibited a higher specific capacitance (260 F/g) as compared to pristine ZnO NFs (118 F/g) at the scan rate of 5 mV/s. Furthermore, the ZnO/CNFs composite also exhibited good capacity retention (73.33%). The obtained results indicated great potential applications of ZnO/CNFs composite in developing energy storage devices with high energy and power densities. The present work might provide a new route for utilizing ZnO based composites for energy storage applications.

AB - HYPOTHESIS: While multiphase flows, particularly droplet dynamics, are ordinary in nature as well as in industrial processes, their mathematical and computational modelling continue to pose challenging research tasks - patent approaches for tackling them are yet to be found. The lack of analytical flow field solutions for non-trivial droplet dynamics hinders validation of computer simulations and, hence, their application in research problems. High-speed videos and computer vision algorithms can provide a viable approach to validate simulations directly against experiments. EXPERIMENTS: Droplets of water (or glycerol-water mixtures) impacting on both hydrophobic and superhydrophobic surfaces were imaged with a high-speed camera. The corresponding configurations were simulated using a lattice-Boltzmann multiphase scheme. Video frames from experiments and simulations were compared, by means of computer vision, over entire droplet impact events. FINDINGS: The proposed experimental validation procedure provides a detailed, dynamic one-on-one comparison of a droplet impact. The procedure relies on high-speed video recording of the experiments, computer vision, and on a software package for the analyzation routines. The procedure is able to quantitatively validate computer simulations against experiments and it is widely applicable to multiphase flow systems in general. PMID- 29574269 TI - A simple way to an ultra-robust superhydrophobic fabric with mechanical stability, UV durability, and UV shielding property. AB - HYPOTHESIS: Development of an ultra-robust superhydrophobic fabric with mechanical stability, UV durability, and UV shielding by a simple method is highly desirable, yet it remains a challenge that current technologies have been unable to fully address. EXPERIMENTS: Herein, the original fabric is immersed into the solution containing ZnO nanoparticle and PDMS (polydimethylsiloxane), and the fiber surfaces are uniformly covered by a ZnO-PDMS layer after thermal treatment at 110 degrees C for 30 min. FINDINGS: Droplets of water and corrosive liquids including strong acid, strong alkali, and saturated salt solution display sphere shape on the ZnO-PDMS coated fabric surface. The stable binding of ZnO PDMS layer onto the fibers allows for the fabric coating with robust superhydrophobicity, and the coated fabric still displays superhydrophobicity after hand twisting, knife scratching, finger touching, and even cycles of sandpaper abrasion. The ZnO-PDMS coated fabric can also keep its superhydrophobic property when exposed to long term UV illumination, demonstrating its UV resistance. Moreover, the uniformly distribution of ZnO nanoparticles on fibers allows the ZnO-PDMS coated fabric to display UV shielding property. PMID- 29574270 TI - Self-assembling behavior of pyrimidine analogues: Unveiling the factors behind morphological diversity. AB - Studying the self-assembly of uracil derivatives has great importance in biochemistry and nanotechnology. Now, in order to architect unique and interesting nucleobase nanostructures, herein, we report a simple, yet robust uracil moiety based platform which is potentially capable to self-assemble into fibrils. The system is validated using eight uracil moiety derivatives and the effect is examined via fluorescence lifetime imaging microscopy (FLIM), field emission scanning electron microscopy (FESEM), steady state DCM fluorescence and fluorescence correlation spectroscopy (FCS). FLIM and FESEM give qualitative information regarding the fibril formation of different morphologies including string, rod, flower, needles etc. Steady state DCM fluorescence and FCS establish a quantitative estimation of the extent of fibril formation. The involvement of hydrogen bonding interaction between NH and CO groups in the fibrillar growth of 5-IU is evoked from the crystallographic study. Again, the key role of different functional groups behind the formation of fibrillar network is investigated through blocking the COO- group of orotic acid with lanthanides. Finally, esterification and N,N'-dimethylation exquisitely explore the role and priority of different groups in the fibril formation of pyrimidine analogues. The results may be useful for understanding the processes of self-assembly of the uracil derivatives and the rationalized design of the uracil based supramolecular structures with specific properties.

AB - Arid biomes are particularly prominent in the Neotropics providing some of its most emblematic landscapes and a substantial part of its species diversity. To understand some of the evolutionary processes underlying the speciation of lineages in the Mexican Deserts, the diversification of Fouquieria is investigated, which includes eleven species, all endemic to the warm deserts and dry subtropical regions of North America. Using a phylogeny from plastid DNA sequences with samples of individuals from populations of all the species recognized in Fouquieria, we estimate divergence times, test for temporal diversification heterogeneity, test for geographical structure, and conduct ancestral area reconstruction. Fouquieria is an ancient lineage that diverged from Polemoniaceae ca. 75.54 Ma. A Mio-Pliocene diversification of Fouquieria with vicariance, associated with Neogene orogenesis underlying the early development of regional deserts is strongly supported. Test for temporal diversification heterogeneity indicates that during its evolutionary history, Fouquieria had a drastic diversification rate shift at ca.12.72 Ma, agreeing with hypotheses that some of the lineages in North American deserts diversified as early as the late Miocene to Pliocene, and not during the Pleistocene. Long-term diversification dynamics analyses suggest that extinction also played a significant role in Fouquieria's evolution, with a very high rate at the onset of the process. From the late Miocene onwards, Fouquieria underwent substantial diversification change, involving high speciation decreasing to the present and negligible extinction, which is congruent with its scant fossil record during this period. Geographic phylogenetic structure and the pattern of most sister species inhabiting different desert nucleus support that isolation by distance could be the main driver of speciation. PMID- 29574272 TI - The Microtus voles: Resolving the phylogeny of one of the most speciose mammalian genera using genomics. AB - Sequential rapid radiations pose some of the greatest difficulties in phylogenetics, especially when analysing only a small number of genetic markers. Given that most of the speciation events occur in quick succession at various points in time, this creates particular challenges in determining phylogenetic relationships, i.e. branching order and divergence times. With the development of high throughput sequencing, thousands of markers can now readily be used to tackle these issues. Microtus is a speciose genus currently composed of 65 species that evolved over the last 2 million years. Although it is a well-studied group, there is still phylogenetic uncertainty at various divergence levels. Building upon previous studies that generally used small numbers of mitochondrial and/or nuclear loci, in this genomic-scale study we used both mitochondrial and nuclear data to study the rapid radiation within Microtus, using partial mitogenomes and genotyping-by-sequencing (GBS) on seven species representing five Microtus subgenera and the main biogeographic ranges where this group occurs. Both types of genome (mitochondrial and nuclear) generated similar tree topologies, with a basal split of the Nearctic (M. ochrogaster) and Holarctic (M. oeconomus) species, and then a subdivision of the five Palearctic species into two subgroups. These data support the occurrence of two European radiations, one North American radiation, and a later expansion of M. oeconomus from Asia to both Europe and North America. We further resolved the positioning of M. cabrerae as sister group of M. agrestis and refute the claim that M. cabrerae should be elevated to its own genus (Iberomys). Finally, the data support ongoing speciation events, especially within M. agrestis, with high levels of genetic divergence between the three Evolutionarily Significant Units (ESUs) previously identified. Similar high levels of divergence were also found among ESUs within M. oeconomus and M. arvalis. PMID- 29574273 TI - Resolving complex phylogeographic patterns in the Balkan Peninsula using closely related wall-lizard species as a model system. AB - The Balkan Peninsula constitutes a biodiversity hotspot with high levels of species richness and endemism. The complex geological history of the Balkans in conjunction with the climate evolution are hypothesized as the main drivers generating this biodiversity. We investigated the phylogeography, historical demography, and population structure of closely related wall-lizard species from the Balkan Peninsula and southeastern Europe to better understand diversification processes of species with limited dispersal ability, from Late Miocene to the Holocene. We used several analytical methods integrating genome-wide SNPs (ddRADseq), microsatellites, mitochondrial and nuclear DNA data, as well as species distribution modelling. Phylogenomic analysis resulted in a completely resolved species level phylogeny, population level analyses confirmed the existence of at least two cryptic evolutionary lineages and extensive within species genetic structuring. Divergence time estimations indicated that the Messinian Salinity Crisis played a key role in shaping patterns of species divergence, whereas intraspecific genetic structuring was mainly driven by Pliocene tectonic events and Quaternary climatic oscillations. The present work highlights the effectiveness of utilizing multiple methods and data types coupled with extensive geographic sampling to uncover the evolutionary processes that shaped the species over space and time. PMID- 29574274 TI - Pharmacokinetics of radiolabeled dimeric sdAbs constructs targeting human CD20. AB - Single-domain antibody fragments (sdAbs) are the smallest functional antigen binding fragments, derived from heavy chain-only camelid antibodies. When designed as radiolabeled monomeric probes for imaging and therapy of cancer, their fast and specific targeting results in high tumor-to-background ratios early after injection. However, their moderate absolute uptake into tumors might not always be sufficient to treat cancerous lesions. We have evaluated the pharmacokinetics of seven constructs derived from a CD20-targeting monomeric sdAb (alphaCD20). The constructs differed in affinity or avidity towards CD20 (dimeric alphaCD20-alphaCD20 and alphaCD20 fused to a non-targeting control sdAb, referred to as alphaCD20-ctrl) and blood half-lives (alphaCD20 fused to an albumin targeting sdAb (alphaAlb) = alphaCD20-alphaAlb). The constructs were radiolabeled with 111In (imaging) and 177Lu (therapy) using the bifunctional chelator CHX-A" DTPA and evaluated in vitro and in vivo. In mice, tumor uptake of 177Lu-DTPA alphaCD20 decreased from 4.82 +/- 1.80 to 0.13 +/- 0.05% IA/g over 72 h. Due to its rapid blood clearance, tumor-to-blood (T/B) ratios of >100 were obtained within 24 h. Although in vitro internalization indicated that dimeric 177Lu-DTPA alphaCD20-alphaCD20 was superior in terms of total cell-associated radioactivity, this was not confirmed in vivo. Blood clearance was slower and absolute tumor uptake became significantly higher for alphaCD20-alphaAlb. Blood levels of 177Lu DTPA-alphaCD20-alphaAlb decreased from 68.30 +/- 10.53 to 3.58 +/- 0.66% IA/g over 120 h, while tumor uptake increased from 6.21 +/- 0.94 to 24.90 +/- 2.83% IA/g, resulting in lower T/B ratios. Taken together, these results indicate that the increased size of dimeric alphaCD20-alphaCD20 or the fusion of monomeric alphaCD20 to an albumin-targeting moiety (alphaAlb) counterbalance their improved tumor targeting capacity compared to monomeric alphaCD20. PMID- 29574275 TI - Anti-CD73 and anti-OX40 immunotherapy coupled with a novel biocompatible enzyme prodrug system for the treatment of recurrent, metastatic ovarian cancer. AB - Approximately 75% of ovarian cancer is diagnosed once metastasis to the peritoneal cavity has occurred. A large proportion of patients eventually develop platinum-resistive tumors, which are considered terminal. In order to provide an alternative a novel fusion protein, mCTH-ANXA5, has been developed for the treatment of recurrent, metastatic ovarian cancer. The fusion protein combines annexin V (ANXA5), an ovarian tumor and tumor vasculature targeting protein, with mutated cystathionine gamma-lyase (mCTH), an enzyme that converts selenomethionine (SeMet) into toxic methylselenol, which generates reactive oxygen species and eventual tumor cell death. In order to further enhance the therapeutic efficacy, anti-CD73 and anti-OX40 immunostimulants were combined with mCTH-ANXA5, resulting in an increase of survival by 100% from 12 to 24 days post therapy and decrease tumor burden in mice with orthotopic metastatic ovarian cancer. Further evaluation of the combination therapy revealed a strong antibody mediated immune response, and an increased infiltration of cytotoxic T-cells along with a decrease in tumor promoting immune cells. This study demonstrates the efficacy of a synergistic, multi-drug system by attacking the tumor as well as enlisting the body's own defense system to treat the patient. PMID- 29574276 TI - CXCR4-mediated signaling regulates autophagy and influences acute myeloid leukemia cell survival and drug resistance. AB - CXCR4 surface expression is considered an independent prognostic factor for disease relapse and survival in acute myeloid leukemia (AML) patients. Herein, we investigated targetable autophagy-related mechanisms of CXCR4 for AML therapy. Our experiments show that activation of CXCR4 signaling in AML cells increases autophagic activity and decreases cytarabine-induced apoptosis. Accordingly, combined use of autophagy inhibitors significantly increased the sensitivity of AML cells to cytarabine in vitro and in vivo. Moreover, expression of autophagy related protein SIRT1 was correlated with SDF-1alpha-CXCR4 signaling, which interacts with autophagy proteins, such as ATG5 and LC3. Furthermore, in primary human AML samples, high CXCR4 expression was associated with elevated expression levels of SIRT1 and other autophagy-related proteins. Collectively, our data suggest new roles of SDF-1alpha-CXCR4 signaling on autophagy induction in AML cells, which further promoted their survival under stress. Targeting the SDF 1alpha-CXCR4-autophagy signaling may contribute to an enhanced efficacy of active treatments. PMID- 29574277 TI - XRCC3 contributes to temozolomide resistance of glioblastoma cells by promoting DNA double-strand break repair. AB - Glioblastoma is the most frequent and aggressive form of high-grade malignant glioma. Due to the dismal prognosis faced by patients suffering from this disease, there is a need for identifying new targets that might improve therapy. The aim of this study was to determine the contribution of the DNA double-strand break (DSB) repair protein X-ray repair cross-complementing 3 (XRCC3) to the resistance of glioma cells to the chemotherapeutic drug temozolomide. Analysis of a publicly available database, E-GEOD-4290, showed that gliomas overexpress XRCC3 (NM_005432) compared to normal brain tissue. Using an isogenic glioma cell system, in which XRCC3 was downregulated by interference RNA, we demonstrate that XRCC3 protects glioma cells against temozolomide-induced reproductive cell death, apoptosis and cell cycle inhibition. Furthermore, XRCC3 knockdown significantly reduced the rate of repair of DSBs following TMZ treatment, which results in increased drug sensitivity. This study confirms the importance of homologous recombination in the resistance of glioma cells to the methylating drug temozolomide and adds XRCC3 to the list of homology-directed DNA repair proteins as possible targets for therapeutic intervention. PMID- 29574278 TI - sjTREC quantification using SYBR quantitative PCR for age estimation of bloodstains in a Japanese population. AB - Individual age is a phenotypic trait that provides useful information in forensic investigations. Levels of signal joint T-cell receptor rearrangement excision circle (sjTREC) in human peripheral blood are known to decline with increasing age. The advantages of sjTREC quantification are the simple procedures and highly accurate age estimation results. Whereas TaqMan quantification PCR (qPCR) is widely used for sjTREC quantification, SYBR qPCR assay is not routinely used for evaluating ethnic data. Therefore, we focused on the advantages of the SYBR qPCR assay, which is cheaper and simpler to set up than the TaqMan probe assay. In this study, we developed a SYBR qPCR assay for sjTREC quantification from bloodstains from a Japanese population and evaluated the strength of correlation between sjTREC levels and actual age. The results were obtained from 194 individuals ranging from 18 to 81 years old, and showed a negative correlation between sjTREC level and individual age (r = -0.786). The equation for age estimation was Age = -6.27 dCt (CtTBP - CtsjTREC) - 25.841 with standard error +/-8.0 years. Furthermore, this formula for the SYBR assay can be applied to not only fresh bloodstains, but also whole blood and bloodstains up to 1 month old. These results indicate that SYBR qPCR is an effective method for age estimation from bloodstains, and its practicality and affordability make it an attractive sjTREC quantification technique. PMID- 29574279 TI - Study on biocompatibility, tribological property and wear debris characterization of ultra-low-wear polyethylene as artificial joint materials. AB - Ultra-low-wear polyethylene (ULWPE) is a new type polyethylene made by experts who are from China petrochemical research institute, which is easy to process and implant. Preliminary test showed it was more resistant to wear than that of Ultra high-molecular weight polyethylene (UHMWPE). The purpose of the research is to study biocompatibility, bio-tribological properties and debris characterization of ULWPE. Cytotoxicity test, hemolysis test, acute/chronic toxicity and muscular implantation test were conducted according to national standard GB/T-16886/ISO 10993 for evaluation requirements of medical surgical implants. We obtained that this novel material had good biocompatibility and biological safety. The wear performance of ULWPE and UHMWPE was evaluated in a pin-on-disc (POD) wear tester within two million cycles and a knee wear simulator within six million cycles. We found that the ULWPE was higher abrasion resistance than the UHMWPE, the wear rate of ULWPE by POD test and knee wear simulator was 0.4 mg/106cycles and (16.9 +/- 1.8)mg/106cycles respectively, while that of UHMWPE was 1.8 mg/106cycles and (24.6 +/- 2.4)mg/106cycles. The morphology of wear debris is also an important factor to evaluate artificial joint materials, this study showed that the ULWPE wear debris gotten from the simulator had various different shapes, including spherical, block, tear, etc. The morphology of worn surface and wear debris analysis showed that wear mechanisms of ULWPE were adhesion wear, abrasive wear and fatigue wear and other wear forms, which were consistent with that of UHMWPE. Thus we conclude that ULWPE is expected to be a lifetime implantation of artificial joint. PMID- 29574280 TI - Glycerol-dimethacrylate as alternative hydrophilic monomer for HEMA replacement in simplified adhesives. AB - OBJECTIVES: Hydroxyethyl-methacrylate (HEMA) is still widely used in simplified adhesives. Indeed, several shortcomings occur with this monomer, such as water uptake and formation of linear polymers. This study aimed to compare the effects of HEMA replacement by glycerol-dimethacrylate (GDMA) on selected physicochemical properties and bonding performance of simplified model adhesives. MATERIALS AND METHODS: Experimental simplified etch-and-rinse and self-etch adhesives were formulated containing 20 wt% HEMA or GDMA. Three-point bending test was used to obtain the elastic modulus of bar-shaped specimens, and water sorption and solubility were attained by ISO-4049 (ISO, 2009) method. Degree of conversion was surveyed by Micro-Raman spectroscopy, and microtensile bond strength was tested after 24 h or 6 months simulated pulpal pressure aging. Statistical analysis was realized with two-way ANOVA and Tukey's test (p < 0.05). RESULTS: GDMA promoted higher elastic modulus to the self-etch adhesive, and GDMA-containing etch-and rinse adhesive achieved overall lower water sorption and solubility. The degree of conversion was statistically higher for GDMA adhesives than for HEMA etch-and rinse one. All bond strengths dropped significantly after aging, except that of GDMA self-etch adhesive. The nanoleakage was higher and gaps were found in the interface of HEMA-containing adhesives, which were less present in GDMA equivalents. CONCLUSIONS: GDMA is a feasible hydrophilic dimethacrylate monomer to replace HEMA in simplified adhesives, thereby providing better polymerization, mechanical properties and dentin adhesion as well as lower water uptake and solubility. PMID- 29574281 TI - The significance of meibomian gland changes in asymptomatic children. AB - PURPOSE: To evaluate meibomian gland morphology and function in children without ocular discomfort. METHOD: A total of 266 eyes of 266 children without signs or symptoms of ocular surface dysfunction were enrolled. Morphology of meibomian glands (MG) and non-invasive break-up time (BUT) was assessed by noncontact meibography. Based on lipid layer thickness (LLT) of the tear film measurements, 66 children were chosen to be assessed by meibomian glands yielding liquid secretion (MGYLS). RESULTS: Based on the presence of physiologic conjunctival follicles (PCF), participants were divided into normal or PCF groups. The distortion and deficiency of MG function was significantly higher in PCF group (P = 0.002, 0.007, respectively). Five different gland duct shapes (vertical, tortuous, overriding, hooked, U-shaped) were observed. MG deficiency was positively correlated with age (R = 0.362, P < 0.001). Distortion and the number of MG showed no correlation with age (P > 0.05). However, distortion and deficiency of MG were negatively correlated with LLT (P < 0.001, P < 0.01). CONCLUSION: Children with PCF had significantly more MG distortion and deficiency which was associated with LLT. These results prompt future studies to determine if changes in MG morphology are congenital or acquired. PMID- 29574282 TI - The anti-inflammatory NHE-06 restores antitumor immunity by targeting NF kappaB/IL-6/STAT3 signaling in hepatocellular carcinoma. AB - The NF-kappaB/IL-6/STAT3 inflammatory axis is highly activated in a variety of inflammation-related cancers and contributes to suppression of antitumor immunity. In this study, we generated a novel herbal formula NHE-06, a water decocting extract from six natural herbals, Ficus carica, Taraxacum mongolicum, Angelica sinensis, Lonicera japonica, Pseudo-ginseng and Folium ginkgo. We investigated the anti-inflammatory properties of NHE-06 and its antitumor efficacy in hepatocellular carcinoma, a typical inflammation-related cancer. We found that NHE-06 effectively suppressed NF-kappaB/IL-6/STAT3 signaling and enhanced antitumor immunity both in vitro and in HCC-bearing mice. In a subcutaneous HCC mouse model, we found that NHE-06 possessed both preventive and therapeutic functions. Moreover, rather than the cytotoxic effects, the antitumor efficacy of NHE-06 was indispensable of intact immunity, since the therapeutic effect was only achieved in immunocompetent mice whereas failed in immunocompromised mice. Taken together, the novel formula of the anti inflammatory NHE-06 effectively restores antitumor immunosurveillance and can be applied for prevention and/or treatment of inflammation-related cancers. PMID- 29574283 TI - VS-5584 as a PI3K/mTOR inhibitor enhances apoptotic effects of subtoxic dose arsenic trioxide via inhibition of NF-kappaB activity in B cell precursor-acute lymphoblastic leukemia. AB - Activation of the phosphoinositide 3-kinase (PI3K)/Akt/mTOR pathway as a survival signaling cascade is a prominent feature of cancers such as acute lymphoblastic leukemia (ALL). In patients with B-cell precursor-ALL (BCP-ALL), the high activity of the pathway correlates with the weak response to anti-leukemic drugs and relapse as a result of downstream prosurvival pathway activation, such as nuclear factor kappa B (NF-kappaB). Recent targeted therapy (PI3K/mTOR inhibitors) in combination with a multifunctional conventional chemotherapeutic drug may be useful for treatment of BCP-ALL patients. In the current study, the potential of a subtoxic dose (0.2 MUM) of arsenic trioxide (ATO) in combination with VS-5584 (a highly potent PI3K/mTOR dual inhibitor) was tested for blocking of the PI3K/Akt/mTOR pathway, inhibition of NF-kappaB activation and induction of apoptosis and cell-cycle arrest. The data indicate that VS-5584 as a PI3K/mTOR inhibitor inhibited cell proliferation and induced apoptosis in NALM-6 cells by means of NF-kappaB transcriptional activity suppression. This apoptotic process markedly increased 72 h after administration of the subtoxic dose of ATO. We also showed that concomitant treatment of VS-5584 and the subtoxic dose of ATO significantly inhibited phosphorylation of NF-kappaB inhibitor alpha (IkappaBalpha) and S6 ribosomal protein (S6) as the downstream proteins of the PI3K/Akt/mTOR pathway. Combining VS-5584 and a subtoxic dose of ATO also resulted in down expression of the NF-kappaB target genes involved in cell proliferation and survival. These results indicate that incorporation of VS-5584/ATO combination into BCP-ALL therapeutic protocols can improve treatment and the survival of patients. PMID- 29574284 TI - Morphology, biology and phylogeny of Phalansterium arcticum sp. n. (Amoebozoa, Variosea), isolated from ancient Arctic permafrost. AB - A new species, Phalansterium arcticum sp. n., was isolated from an 8580-year-old Arctic permafrost layer. This organism typically lives as a sedentary uniflagellated cell enclosed in a thin flexible mucilaginous sheath, but can form naked swimming cells and amoeboid cells with eruptive pseudopodia accompanied with the formation of short, filopodia-like projections. In an SSU rDNA phylogenetic tree, it robustly groups with other species of this genus. Along with a description of the species, we also add new details to the description of the cell division of Phalansterium and the feeding process in this organism. PMID- 29574285 TI - Time course of reversal of valproate-mediated inhibition of lamotrigine. AB - PURPOSE: Conversion to lamotrigine (LTG) monotherapy from sodium valproate (VPA) is complicated by the robust pharmacokinetic interaction between the two AEDs. This study examined changes in LTG serum concentrations immediately following VPA discontinuation. METHODS: Ten healthy female and male adult subjects were initiated on LTG (Lamictal) 10 mg orally every morning for 30 days and VPA (Depakote ER) 500 mg orally every morning for 14 days. Morning trough (pre-dose) venous blood samples were obtained for determination of LTG and VPA concentrations on study days 14, 15, 16, 18, 20, 22, 24, 26, 28, and 30. Following the collection of the blood sample on day 15, VPA was discontinued. RESULTS: Despite stable LTG dosage serum concentrations on study day 20, 22, 24, 26, and 28, all were significantly lower compared to baseline (p < 0.05). CONCLUSIONS: These observations demonstrate that the pharmacokinetic interaction between LTG and VPA is reversible, and that de-inhibition appears to follow a predictable time course. Complete offset, or reversal of this interaction takes place 10-14 days after VPA discontinuation. Our data also confirms the observation that LTG oral clearance may be inhibited by very low concentrations of VPA. These data support the conversion algorithm suggested by the manufacturer, and provide guidance to the clinician. These data provide clinically useful information in developing a dosing algorithm for converting patients to LTG monotherapy.

AB - STUDY OBJECTIVE: Possible advantages and risks associated with ultrasound guided radial artery cannulation in-comparison to digital palpation guided method in adult patients are not fully known. We have compared ultrasound guided radial artery cannulation with digital palpation technique in this meta-analysis. DESIGN: Meta-analysis of randomized controlled trials. SETTING: Trials conducted in operating room, emergency department, cardiac catheterization laboratory. PATIENTS: PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) were searched (from 1946 to 20th November 2017) to identify prospective randomized controlled trials in adult patients. INTERVENTION: Two-dimensional ultrasound guided radial artery catheterization versus digital palpation guided radial artery cannulation. MEASUREMENTS: Overall cannulation success rate, first attempt success rate, time to cannulation and mean number of attempts to successful cannulation. Odds ratio (OR) and standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval (CI) were calculated for categorical and continuous variables respectively. RESULTS: Data of 1895 patients from 10 studies have been included in this meta- analysis. Overall cannulation success rate was similar between ultrasound guided technique and digital palpation [OR (95% CI) 2.01 (1.00, 4.06); p = 0.05]. Ultrasound guided radial artery cannulation is associated with higher first attempt success rate of radial artery cannulation in comparison to digital palpation [OR (95% CI) 2.76 (186, 4.10); p < 0.001]. No difference was seen in time to cannulate [SMD (95% CI) 0.31 (-0.65, 0.04); p = 0.30] and mean number of attempt [MD (95% CI) -0.65 ( 1.32, 0.02); p = 0.06] between USG guided technique with palpation technique. CONCLUSION: Radial artery cannulation by ultrasound guidance may increase the first attempt success rate but not the overall cannulation success when compared to digital palpation technique. However, results of this meta-analysis should be interpreted with caution due presence of heterogeneity. PMID- 29574289 TI - Anaesthetic challenges of Ellis-van Creveld syndrome. PMID- 29574290 TI - Evaluation of in-situ fatty acid extraction protocols for the analysis of staphylococcal cell membrane associated fatty acids by gas chromatography. AB - The composition and integrity of the bacterial cytoplasmic membrane is critical to the survival of staphylococci in dynamic environments and it is important to investigate how the cell membrane responds to changes in the environmental conditions. The staphylococcal membrane differs from eukaryotic and many other bacterial cell membranes by having a high abundance of branch fatty acids and relatively few unsaturated fatty acids. The range of available methods for extraction and efficient analyses of staphylococcal fatty acids was initially appraised to identify the best potential procedures for appraisal. Staphylococcus aureus subsp. aureus Rosenbach (ATCC(r) 29213) was grown under optimal conditions to generate a cell biomass to compare the efficiencies of three approaches to extract and prepare methyl esters of the membrane fatty acids: (1) acidic direct transesterification of lipids, (2) modified basic direct transesterification of membrane lipids with adjusted reaction times and temperatures, and (3) base catalysed hydrolysis followed by acid catalysed esterification in two separate chemical reactions (MIDI process). All methods were able to extract fatty acids from the cell mass effectively where these lipids represented approximately 5% of the cellular dry mass. The acidic transesterification method had the least number of steps, the lowest coefficient of variation at 6.7% and good resistance to tolerating water. Basic transesterification was the least accurate method showing the highest coefficient of variation (26%). The MIDI method showed good recoveries, but had twice the number of steps and a coefficient of variation of 16%. It was also found that there was no need to use an anti-oxidant such as BHT for the protection of polyunsaturated fatty acids when the GC-MS injection liner was clean. It was concluded that the acidic transesterification procedures formed the most efficient and reproducible method for the analyses of staphylococcal membrane fatty acids.

AB - Aneurysmal enlargement of the left atrial appendage is an extremely rare pathology and can predispose to adverse events, including cardiac arrest, respiratory distress, arrhythmia, heart failure, systemic thromboembolism, or rupture. It is usually diagnosed incidentally or after the occurrence of atrial tachyarrhythmias or thrombotic events in the second to fourth decades of life. We describe a rare case of a symptomatic giant congenital left atrial appendage aneurysm (LAAA) in a 26-year-old man presenting with neurologic event, in whom surgical resection of the aneurysm was successfully performed. This is the largest LAAA reported in the literature so far. PMID- 29574292 TI - Does health insurance coverage or improved quality protect better against out-of pocket payments? Experimental evidence from the Philippines. AB - This paper explores whether health insurance coverage or improved quality at the hospital level protect better against out-of-pocket payments. Using data from a randomized policy experiment in the Philippines, we found that interventions to expand insurance coverage and improve provider quality both had an impact on out of-pocket payments. The sample consists of 3121 child-patient patient observations across 30 hospitals either at baseline in 2003/04 or at the follow up in 2007/08. Compared to controls, interventions that expanded insurance and provided performance-based provider payments to improve quality both resulted in a decline in out-of-pocket spending (21% decline, p-value = 0.061; and 24% decline, p-value = 0.017, respectively). With lower out-of-pocket payments for hospital care, monthly household spending on personal hygiene rose by 0.9 (p value = 0.026) and 0.6 US$ (p-value = 0.098) under the expanded insurance and provider payment interventions, respectively, amounting to roughly a 40-60% increase relative to the controls. With the current surge for health insurance expansion in developing countries, our study suggests paying increased and possibly, equal attention to supply-side interventions will have similar impacts with operational simplicity and greater provider accountability.

AB - A method for the preparation of benzene derivatives from myo-inositol, an abundantly available phyto chemical is described. 1,3-Bridged acetals of inososes undergo step-wise elimination leading to the formation of polyoxygenated benzene derivatives. This aromatization reaction proceeds through the intermediacy of a beta-alkoxyenone, which could be isolated. This sequence of reactions starting from myo-inositol, provides a novel route for the preparation of polyoxygenated benzene derivatives including polyoxygenated biphenyl. This scheme of synthesis demonstrates the potential of myo-inositol as a sustainable non-petrochemical resource for aromatic compounds. PMID- 29574294 TI - Examining the utility of a train-the-trainer model for dissemination of sexual violence prevention in schools. AB - Rates of childhood sexual abuse are unacceptably high, with potentially long lasting consequences for those who have been victimized. Currently, there are a number of sexual violence prevention programs that have been developed to lower rates of victimization, increase awareness, and connect victims with resources. Within this area of research, there has been less focus on effective methods of program dissemination. For example, school-based sexual violence prevention programs have had positive outcomes; however, little is known about how these programs are disseminated. The train-the-trainer model of dissemination utilizes master trainers to equip others to implement programs, thereby allowing more adults to teach and subsequently more children to receive the program. This study used survey data from teachers and other school personnel (n = 127) to analyze the utility of a train-the-trainer model of dissemination for a sexual violence prevention program in the state of Hawai'i. Through responses of people who were trained to implement the program (59.8% of whom did implement), aspects of the training, the program itself, and factors affecting whether a person implemented the program were explored. Results suggest that time spent in training, job position, and time in that position predicted whether a person trained to implement the sexual violence prevention program followed through with teaching the program to students. Additionally, 54.7% of people who did implement the program had at least one student disclose sexual violence to them, indicating the importance of sexual violence prevention programming and dissemination of these programs. PMID- 29574296 TI - Novel prodrug PRX-P4-003, selectively activated by gut enzymes, may reduce the risk of iatrogenic addiction and abuse. AB - OBJECTIVES: Prescription stimulants are vulnerable to oral and parenteral abuse. Intravenous forms of abuse may be most detrimental due to an enhanced risk of dependence, overdose, and infectious diseases. Our objective was to discover an orally active prodrug of a stimulant that would not be easily converted to its parent when injected, thus hindering intravenous abuse. METHODS: Following an initial analysis of stimulant structures, the fencamfamine isomer [(-)-FCF; (N ethyl-3-phenylbicyclo[2.2.1]heptan-2-amine)] was chosen as a parent drug due to its favorable biochemical properties. Subsequently, PRX-P4-003 {(-)-N (Octadecanoyloxymethoxycarbonyl)-N-ethyl-3-phenylbicyclo[2.2.1]heptan-2-amine} qualified for further development. Experimental testing of PRX-P4-003 included radioligand binding assays, stability studies, and rodent pharmacokinetic and locomotor assays. RESULTS: Prodrug PRX-P4-003 is a pharmacologically inactive, hydrophobic compound, whereas its parent (-)-FCF is a dopamine reuptake inhibitor with weaker effects on norepinephrine reuptake (Ki = 0.07 and 0.80 MUM, respectively). PRX-P4-003 is metabolized to (-)-FCF in simulated intestinal fluid (with pancreatin) but not in simulated gastric fluid (with pepsin). Finally, PRX P4-003 shows a significant oral but no intravenous increase in locomotion, correlating with its pharmacokinetics by these different routes of administration. CONCLUSIONS: PRX-P4-003 is a novel prodrug stimulant enzymatically activated in the gut. Our data suggest a pancreatic, lipase-based mechanism of activation and as only 1% of this enzyme is found in the systemic circulation, PRX-P4-003 is unlikely to be bioactive if injected intravenously. Enzymatic release of (-)-FCF is needed prior to its systemic absorption, which may discourage oral abuse (e.g., by chewing). PRX-P4-003 is being developed for apathy in Alzheimer's disease and binge eating disorder. PMID- 29574295 TI - Self-reported neglect, amygdala volume, and symptoms of anxiety in adolescent boys. AB - Experiences of psychosocial neglect affect the developing brain and may place individuals at increased risk for anxiety. The majority of research in this area has focused on children who have experienced severe psychosocial deprivation; it is not clear whether typical variation in neglect experienced in community samples would have the same neurobiological consequences as those documented in extreme samples. The present study examined the associations among self-reported childhood neglect, amygdala volume, and anxiety symptoms in a community sample of 138 adolescents ages 9-15 years (43% male). Linear mixed modeling yielded a three way interaction of neglect, sex, and brain hemisphere, reflecting a significant positive association between neglect and right amygdala volume in boys. Additional analyses indicated that right amygdala volume significantly mediated the association between neglect and anxiety symptoms in boys. These findings are consistent with previous reports of larger amygdala volumes in previously institutionalized children, and with documented associations between caregiving deprivation and anxiety symptoms. The results suggest that the effects of childhood neglect on limbic structures are sex-specific and lateralized, and provide support for a neural mechanism relating childhood neglect to later difficulties in emotional functioning. PMID- 29574297 TI - Gender differences in prevalence of psychiatric disorders, levels of alexithymia, and coping strategies in patients with refractory mesial temporal epilepsy and comorbid psychogenic nonepileptic seizures. AB - OBJECTIVE: The objective of this study was to investigate the psychological aspects and psychiatric disorders (PDs) in patients dually diagnosed with refractory temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) with psychogenic nonepileptic seizures (PNES) treated in a tertiary center in order to find any gender differences in psychiatric, clinical, and sociodemographic characteristics. METHOD: Psychiatric assessment was performed through the Diagnostic and Statistical Manual for Psychiatric Disorders - 5th edition (DSM 5). The Brazilian versions of the Medical Outcomes Study 36 (SF-36), Toronto Alexithymia Scale (TAS-20), Hamilton Depression Scale (HAM-D), Hamilton Anxiety Scale (HAM-A), and Ways of Coping Checklist (WCC) were applied. RESULTS: Of the 47 patients enrolled (25 females; 53.2%), females were significantly more likely to have a history of previous psychiatric treatment (P=0.02), family history of epilepsy (P=0.01), and family history of PD (P=0.03). They also presented earlier onset of PNES (P=0.01) and higher PNES duration (P=0.02) compared with males. Major depressive disorder (MDD) was the most frequent PD (24; 51.0%). Females presented more psychiatric diagnoses (P<0.001), more diagnoses of MDD (P<0.001), and posttraumatic stress disorder (PTSD) (P<0.001). Several differences regarding quality of life, levels of alexithymia, anxiety/depressive symptoms, and coping strategies were observed between groups. CONCLUSIONS: There are significant gender differences in psychiatric, clinical, and sociodemographic aspects in a group of patients with TLE-MTS and PNES, as well as in quality of life, levels of alexithymia, anxiety/depressive symptoms, and coping strategies. These gender differences suggest that specific approaches might be adopted depending on the patient's gender and, consequently, their distinct psychological/psychiatric profile. PMID- 29574298 TI - The relevance of timing in nonconvulsive status epilepticus: A series of 38 cases. AB - BACKGROUND: Timing in the management of nonconvulsive status epilepticus (NCSE) seems to be one of the most important modifiable prognostic factors. We aimed to determine the precise relationship between timing in NCSE management and its outcome. METHODS: We performed a cross-sectional study in which clinical data were prospectively obtained from all consecutive adults with NCSE admitted to our hospital from 2014 to 2016. Univariate and multivariable regression analyses were performed to identify clinical and timing variables associated with NCSE prognosis. RESULTS: Among 38 NCSE cases, 59.9% were women, and 39.5% had prior epilepsy history. The median time to treatment (TTT) initiation and the median time to assessment by a neurologist (TTN) were 5h, and the median time to first electroencephalography assessment was 18.5h; in the cases with out-of-hospital onset (n=24), the median time to hospital (TTH) arrival was 2.8h. The median time to NCSE control (TTC) was 16.5h, and it positively correlated with both the TTH (Spearman's rho: 0.439) and the TTT (Spearman's rho: 0.683). In the multivariable regression analyses, the TTC was extended 1.7h for each hour of hospital arrival delay (p=0.01) and 2.7h for each hour of treatment delay (p<0.001). Recognition delay was more common in the episodes with in-hospital onset, which also had longer TTN and TTC, and increased morbidity. CONCLUSIONS: There were pervasive delays in all phases of NCSE management. Delays in hospital arrival or treatment initiation may result in prolonged TTC. Recognition of in-hospital episodes may be more delayed, which may lead to poorer prognosis in these cases. PMID- 29574299 TI - Deep facial analysis: A new phase I epilepsy evaluation using computer vision. AB - Semiology observation and characterization play a major role in the presurgical evaluation of epilepsy. However, the interpretation of patient movements has subjective and intrinsic challenges. In this paper, we develop approaches to attempt to automatically extract and classify semiological patterns from facial expressions. We address limitations of existing computer-based analytical approaches of epilepsy monitoring, where facial movements have largely been ignored. This is an area that has seen limited advances in the literature. Inspired by recent advances in deep learning, we propose two deep learning models, landmark-based and region-based, to quantitatively identify changes in facial semiology in patients with mesial temporal lobe epilepsy (MTLE) from spontaneous expressions during phase I monitoring. A dataset has been collected from the Mater Advanced Epilepsy Unit (Brisbane, Australia) and is used to evaluate our proposed approach. Our experiments show that a landmark-based approach achieves promising results in analyzing facial semiology, where movements can be effectively marked and tracked when there is a frontal face on visualization. However, the region-based counterpart with spatiotemporal features achieves more accurate results when confronted with extreme head positions. A multifold cross-validation of the region-based approach exhibited an average test accuracy of 95.19% and an average AUC of 0.98 of the ROC curve. Conversely, a leave-one-subject-out cross-validation scheme for the same approach reveals a reduction in accuracy for the model as it is affected by data limitations and achieves an average test accuracy of 50.85%. Overall, the proposed deep learning models have shown promise in quantifying ictal facial movements in patients with MTLE. In turn, this may serve to enhance the automated presurgical epilepsy evaluation by allowing for standardization, mitigating bias, and assessing key features. The computer-aided diagnosis may help to support clinical decision making and prevent erroneous localization and surgery. PMID- 29574300 TI - People with epilepsy and their relatives want more information about risks of injuries and premature death. AB - For most people with chronic diseases such as epilepsy, thorough knowledge of the disease is important in order to reduce feelings of insecurity and to enable better management of everyday life. Whether and when to inform patients and their families about all the risks associated with epilepsy is a matter of controversy. Using a web-based survey, patients with epilepsy (PWE) (n=1183) and carers, family members, or guardians of PWE, who could either answer on behalf of the patients (CBP) (n=676) or on their own behalf (CAR) (n=231) were asked whether they wanted information about the risk of epilepsy-related injuries and premature death and also whether they had received such information. Ninety percent or more of PWE, CBP, and CAR reported that they wanted such information, and 50% of CAR, 81% of CBP, and 70% of PWE had received some information about seizure-related injuries. Regarding risk of unexpected death, 31% of PWE, 35% of CBP, and 28% of CAR had received information on this issue. Those with tonic-clonic seizures were most eager to obtain information on these matters, and those best informed about epilepsy-related risks were males and the youngest part of the cohort. The wish for more information or the likelihood of having already received information was independent of the individual's seizure situation. This study demonstrates that there is a considerable gap between what the patients want regarding information and what they are actually given by healthcare providers. PMID- 29574301 TI - A systematic review and meta-synthesis of the impact of becoming parents on the couple relationship. AB - BACKGROUND: the transition to parenthood (TTP) is associated with changes to a couple's relationship. Quantitative evidence shows the TTP is associated with reduced satisfaction and quality of a couples' relationships. Qualitative research provides information on the lived experience of couples in the TTP so can provide a more in-depth understanding of the impact. This review therefore aimed to synthesise qualitative research of the perceived impact of the TTP on a couple's relationship in contemporary Western society. DESIGN: a systematic search was conducted of nine databases and grey literature. Key author, citation and reference searches were also undertaken. Papers were included if they presented qualitative data of romantic partner relationships during the TTP with parents aged 18 or over. Studies were restricted to those conducted from 1996 in Western societies. Analysis was conducted using meta-ethnography. FINDINGS: searches identified 5256 papers. After applying inclusion criteria 12 papers were included in the meta-synthesis. Six main themes were identified: (1) Adjustment Phase (a period of change in the relationship), (2) Focus on the Baby (with a sub theme of feeling unprepared for the relationship impact), (3) Communication (shifts in communication patterns and importance), (4) Intimacy (changes to sexual relations, romance and closeness), (5) Strain on the Relationship (short term or prolonged), and (6) Strengthened Relationships (deepening of connection and new affinity). Except for the themes of Strain on the Relationship and Strengthened Relationships, the findings showed the TTP had positive and negative impacts on couples' relationships. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: the review highlights a range of TTP relationship issues that couples experience and may require help with. Health care professionals working with parents in the TTP may be able to provide support through antenatal education that includes preparation for relationship changes, and provision of postnatal support to identify and overcome problems.

KCh 6651 in transformation of 17alpha-methyltestosterone. AB - In this work, 17alpha-methyltestosterone was effectively hydroxylated by Absidia coerulea KCh 93, Syncephalastrum racemosum KCh 105 and Chaetomium sp. KCh 6651. A. coerulea KCh 93 afforded 6beta-, 12beta-, 7alpha-, 11alpha-, 15alpha-hydroxy derivatives with 44%, 29%, 6%, 5% and 9% yields, respectively. S. racemosum KCh 105 afforded 7alpha-, 15alpha- and 11alpha-hydroxy derivatives with yields of 45%, 19% and 17%, respectively. Chaetomium sp. KCh 6651 afforded 15alpha-, 11alpha-, 7alpha-, 6beta-, 9alpha-, 14alpha-hydroxy and 6beta,14alpha-dihydroxy derivatives with yields of 31%, 20%, 16%, 7%, 5%, 7% and 4%, respectively. 14alpha-Hydroxy and 6beta,14alpha-dihydroxy derivatives were determined as new compounds. Effect of various sources of nitrogen and carbon in the media on biotransformations were tested, however did not affect the degree of substrate conversion or the composition of the products formed. The addition of alpha- or beta-naphthoflavones inhibited 17alpha-methyltestosterone hydroxylation but did not change the percentage composition of the resulting products. PMID- 29574303 TI - Prevalence and correlates of antipsychotic polypharmacy in Hong Kong. AB - BACKGROUND: Antipsychotic polypharmacy (APP) remains a common practice despite inconclusive empirical evidence of additional efficacy and potential exacerbation of side effects. Previous studies suggest APP rate is notably high in East Asia. This paper aims to investigate the prevalence and correlates of APP in Hong Kong. METHOD: This was a cross-sectional study of 728 patients with psychosis. The demographics and clinical information, including age, gender, diagnosis, hospitalization history, and medication were collected. Chi-square tests and logistic regression analyses were used to study correlates of APP. RESULTS: The APP rate for psychosis was 24.2% (n = 728) and that for schizophrenia was 26.0% (n = 611), both considerably lower than our previous local data and that from East Asian regions. The most widely used APP prescription fell within the atypical/atypical combination (i.e., Amisulpride/Clozapine and Paliperidone/Olanzapine), and Olanzapine was the most commonly prescribed antipsychotic. At least 75% of APP patients with psychosis took at least one type of atypical antipsychotics in their medical regimen. Typical/typical polypharmacy was associated with older age and use of antiparkinson drugs. Typical/atypical polypharmacy was associated with the use of antiparkinson drugs and anxiolytics, as well as inpatient status. Atypical/atypical polypharmacy was associated with younger age, inpatient status, and the use of mood stabilizers. CONCLUSION: Overall, our study highlights a relatively low APP rate in Hong Kong when compared to other countries in East Asia. Age, inpatient status and use of antiparkinson drugs, anxiolytics and mood stabilizers were associated with use of APP. PMID- 29574304 TI - An in vitro study on noradrenergic modulation of final oocyte maturation in the catfish Heteropneustes fossilis. AB - This study was aimed to elucidate in vitro the effects of endogenous catecholamines: dopamine (DA), noradrenaline (NA) and adrenaline (A), and the beta-adrenergic blocker propranolol on induction of final oocyte maturation (FOM) in the catfish Heteropneustes fossilis. With this aim, post vitellogenic follicles from sexually mature gravid female catfish were incubated with each of DA, NA and A in a concentration range of 5-250 MUM, and propranolol in a concentration range of 1-200 MUg/mL at time points varying from 0 to 30 h). Translucent follicles without germinal vesicle (GV) and opaque follicles with GV were scored separately for the calculation of percentage germinal vesicle breakdown (GVBD), an index of FOM. Data were analyzed by one-way ANOVA and were considered statistically significant when P values were less than 0.05. The analysis of the data showed that the incubation with NA only stimulated GVBD in a concentration - and time-dependent manner. Though the incubation with propranolol decreased total follicular cAMP level significantly at and above 10 MUg/mL concentrations, a significant effect of the GVBD increase was noticed at 50 MUg/mL or higher. However, the 10 MUg/mL concentration of propranolol was effective to inhibit the NA-induced GVBD significantly albeit at a low level (39%). The present study suggests that final oocyte maturation is modulated by NA through a beta-adrenergic mechanism, implicating a neural control of oocyte maturation and ovulation in teleosts. PMID- 29574305 TI - Proliferative and apoptotic changes in the healthy canine endometrium and in cystic endometrial hyperplasia. AB - Proliferation and apoptosis play an important role in cyclic changes in the healthy canine endometrium. Proteins of the Bcl-2-family are known to be involved in the regulation of apoptosis. However, only few reports mention their expression patterns during cystic endometrial hyperplasia (CEH). In order to correlate proliferative and apoptotic processes, expression of the apoptosis regulatory proteins Bcl-2 (anti-apoptotic) and Bax (pro-apoptotic) in healthy and cystic hyperplastic endometrial tissue as well as in pyometra was investigated. Uteri from 33 bitches were assigned to three groups: group 1 - healthy endometrium (n = 12), group 2 - CEH (n = 17) and group 3 - pyometra (n = 4). Markers for proliferation (Ki-67) and apoptosis (activated caspase-3 and TUNEL method) as well as expression of Bcl-2 and Bax were determined in all endometrial layers. For groups 1 and 2 this was done during endometrial gland secretion in mid and late luteal phase (mLP, lLP), endometrial reparation in early anestrus (eAE) and in the regenerated endometrium in late anestrus (lAE). For group 3 only the late luteal phase was investigated. In group 1, cyclic proliferation patterns were found predominantly in superficial glands (SG) and stroma, whereas progesterone-mediated low expression levels coincided with high apoptosis rates in the basal glands (BG). In eAE, higher apoptotic activity was detected compared to lLP and lAE. Bcl-2 and Bax expression levels showed an inverse cyclic relationship in all tissue layers. In the stroma, in eAE, a rise in proliferative activity and concomitant increase in anti-apoptotic Bcl-2 expression levels was found, indicating that this layer serves as a source for endometrial regeneration. In CEH, no or limited cyclic patterns of proliferation, apoptosis, Bcl-2 and Bax were found. Increased proliferation rates coincided with deregulated apoptosis. Besides the glandular compartments, the stroma played an important role in the pathogenesis of canine CEH. In case of pyometra, both proliferation and apoptosis increased, indicating irreversible damage of the inflamed canine endometrium. In conclusion Bcl-2 and Bax play a role both in the physiological regenerative processes of the cyclic canine endometrium and in deregulating proliferation and apoptosis in CEH and pyometra. PMID- 29574306 TI - Quantifying known and emerging uterine pathogens, and evaluating their association with metritis and fever in dairy cows. AB - Metritis is caused by polymicrobial infection; however, recent metagenomic work challenges the importance of known pathogens such as Escherichia coli and Trueperella pyogenes while identifying potential new pathogens such as Bacteroides pyogenes, Porphyromonas levii and Helcococcus ovis. This study aims to quantify known and emerging uterine pathogens, and to evaluate their association with metritis and fever in dairy cows. Metritis was diagnosed at 6 +/ 2 days postpartum, a uterine swab was collected and rectal temperature was measured. 39 cows were classified into three groups: Healthy (n = 14), Metritis without fever (MNoFever; n = 12), and Metritis with fever (MFever; n = 13). Absolute copy number was determined for total bacteria and for 8 potentially pathogenic bacteria using droplet digital PCR. Both MNoFever and MFever cows had higher copy number of total bacteria, Fusobacterium necrophorum, Prevotella melaninogenica, Bacteroides pyogenes, Porphyromonas levii, and Helcococcus ovis than Healthy cows. MNoFever and MFever groups were similar. There was no difference among groups in copy number of Escherichia coli, Trueperella pyogenes, and Bacteroides heparinolyticus, and they all had low copy numbers. Our work confirms the importance of some bacteria identified by culture-based studies in the pathogenesis of metritis such as Fusobacterium necrophorum and Prevotella melaninogenica; however, it challenges the importance of others such as Escherichia coli and Trueperella pyogenes at the time of metritis diagnosis. Additionally, Bacteroides pyogenes, Porphyromonas levii, and Helcococcus ovis were recognized as emerging pathogens involved in the etiology of metritis. Furthermore, fever was not associated with the total bacterial load or specific bacteria. PMID- 29574307 TI - Immunocastration of goats using anti-gonadotrophin releasing hormone vaccine. AB - The aim of this study was to evaluate the immuno-sterilizing action of anti gonadotrophin-releasing hormone (anti-GnRH) vaccine in goats. Eighteen male goats were randomly distributed to receive three treatments: T1 (control) - whole animals, and T2 and T3 - application of 0.5 and 1.0 mL of anti-GnRH vaccine, respectively, with six replicates and one goat per experimental unit. Vaccine was administered at 8 months of age and 30 days after the first immunization. Testicular biometry was evaluated monthly, along with seminal collections, for the physical and morphological evaluation of semen. At the time of slaughter, the testicle were collected, and fragments were measured and removed for histological evaluation. The data were evaluated for normality by the Shapiro-Wilk test, followed by appropriate statistical tests for each variable. A reduction in width and length of the right and left testicles was observed and, consequently, the scrotal circumference of the immunized animals reduced after the second vaccine application (P < 0.05). Thirty-days after the first vaccine application, there was a negative effect on seminal production and quality; and 60 days after the second application, a pronounced reduction was observed in all seminal parameters in the vaccinated animals, including azoospermia (83.33% of animals; P < 0.05). Vaccine application reduced testicular weight, seminiferous tubule diameter, and gonadosomatic and tubulosomatic index (P < 0.05), but did not influence the proportion of testicular parenchyma components (P > 0.05). Two applications of the anti-GnRH conjugate are effective for the immunological castration of goats, and the 0.5 mL dose is recommended for use in crossbred goats. PMID- 29574308 TI - The influence of hypoxia and IFN-gamma on the proteome and metabolome of therapeutic mesenchymal stem cells. AB - Over the past 15 years, mesenchymal stem cells (MSCs) have been assessed for their capacity to suppress inflammation and promote tissue repair. Regardless of whether the cells are primed (exposed to instructive cues) before administration, their phenotype will respond to environmental signals present in the pathophysiological setting being treated. Since hypoxia and inflammation coexist in the settings of acute injury and chronic disease we sought to explore how the proteome and metabolome of MSCs changes when cells were exposed to 48 h of 1% oxygen, interferon gamma (IFN-gamma), or both cues together. We specifically focused on changes in cell metabolism, immune modulation, extracellular matrix secretion and modification, and survival capacity. IFN-gamma promoted expression of anti-pathogenic proteins and induced MSCs to limit inflammation and fibrosis while promoting their own survival. Hypoxia instead led to cell adaptation to low oxygen, including upregulation of proteins involved in anaerobic metabolism, autophagy, angiogenesis, and cell migration. While dual priming resulted in additive effects, we also found many instances of synergy. These data lend insight to how MSCs may behave after administration to a patient and suggest how priming cells beforehand could improve their therapeutic capacity. PMID- 29574309 TI - Vehicle manoeuvers as surrogate safety measures: Extracting data from the gps enabled smartphones of regular drivers. AB - Network screening is a key element in identifying and prioritizing hazardous sites for engineering treatment. Traditional screening methods have used observed crash frequency or severity ranking criteria and statistical modelling approaches, despite the fact that crash-based methods are reactive. Alternatively, surrogate safety measures (SSMs) have become popular, making use of new data sources including video and, more rarely, GPS data. The purpose of this study is to examine vehicle manoeuvres of braking and accelerating extracted from a large quantity of GPS data collected using the smartphones of regular drivers, and to explore their potential as SSMs through correlation with historical collision frequency and severity across different facility types. GPS travel data was collected in Quebec City, Canada in 2014. The sample for this study contained over 4000 drivers and 21,000 trips. Hard braking (HBEs) and accelerating events (HAEs) were extracted and compared to historical crash data using Spearman's correlation coefficient and pairwise Kolmogorov-Smirnov tests. Both manoeuvres were shown to be positively correlated with crash frequency at the link and intersection levels, though correlations were much stronger when considering intersections. Locations with more braking and accelerating also tend to have more collisions. Concerning severity, higher numbers of vehicle manoeuvres were also related to increased collision severity, though this relationship was not always statistically significant. The inclusion of severity testing, which is an independent dimension of safety, represents a substantial contribution to the existing literature. Future work will focus on developing a network screening model that incorporates these SSMs. PMID- 29574310 TI - High serum IGF-1 levels are associated with pregnancy loss following frozen thawed euploid embryo transfer cycles. AB - An elevated level of insulin growth factor (IGF-1) in rat uterine fluid has been shown to exert detrimental effects of embryo development possibly leading to an increase in pregnancy loss. Interestingly, the administration of somatostatin to rats undergoing superovulation reduced IGF-1 levels in uterine luminal fluid and thus reversed its deleterious effects on embryo development and increased the number of normal embryos. Therefore, we investigated whether serum levels of IGF 1 correlate with the incidence of pregnancy loss following IVF. To account for aneuploidy and the effect of hormonal supplementation on serum IGF levels, we only included natural frozen-thawed euploid embryo transfer (N-FET) cycles. Sera collected in the follicular phase (cycle day 10) were tested for levels of IGF-1, IGF-2, and IGF-binding protein 1 (IGFBP-1) using quantitative ELISA. A total of 156 N-FET cycles were included: 120 resulted in a live birth whereas 36 led to a first trimester pregnancy loss. Women with a pregnancy loss had significantly higher serum IGF-1 levels compared to those who achieved a live birth (18.0 +/- 1.1 vs. 14.6 +/- 0.7 ng/mL, respectively). The two groups had comparable serum IGF-2 and IGFBP-1 levels. There was no significant difference in maternal age, body mass index, gravidity, parity, number of prior miscarriages, peak endometrial thickness, or infertility diagnosis between the two groups. In conclusion, women undergoing euploid blastocyst transfer with elevated serum IGF 1 concentrations may be at increased risk of pregnancy loss. This may constitute a novel molecular explanation of pregnancy loss of euploid conceptus. PMID- 29574311 TI - Fabrication of CDs/CdS-TiO2 ternary nano-composites for photocatalytic degradation of benzene and toluene under visible light irradiation. AB - An efficient cadmium sulfide quantum-dots (CdS QDs) and carbon dots (CDs) modified TiO2 photocatalyst (CdS/CDs-TiO2) was successfully fabricated. The as prepared ternary nano-composites simultaneously improved the photo-corrosion of CdS and amplified its photocatalytic activity. The introduction of CdS QDs and CDs could enhance more absorbance of light, prevent the undesirable electron/hole recombination, and promote charge separation, which was important for the continuous formation of OH and O2- radicals. When the optimal mass ratio of CdS QDs to CDs was 3:1, above 90% degradation efficiencies were achieved for benzene within 1h and toluene in 2h, while that of pure TiO2 (P25), CdS QDs-TiO2, CDs TiO2 nano-composites was around 15%. Owing to the symmetric structure and conjugation of methyl with benzene ring, the degradation of toluene was more difficult than benzene to carry on. The new fabricated nano-composites showed good prospective application of cleaning up refractory pollutants and the resource utilization.

AB - In this work a unique hetero-metallic alkaline earth-transition Ba-Cd luminescent micro-porous metal-organic framework {[BaCd(MU6-tp)1.5(MU2-Cl)(H2O) (DMF)2].0.75H2O}n (H2tp=terephthalic acid) (1) has been prepared under solvo thermal conditions. In 1 infinite 1D {Ba-X-Cd} (X=O, Cl) inorganic chains are linked via these full de-pronated tp2- ligands forming a unique 3D I1O2 type micro-porous coordination framework. PXRD patterns of 1 have been determined confirming pure phases of 1. Luminescence investigations suggested that 1 exhibits highly selective and sensitive sensing for trace amounts of benzaldehyde in ethanol, which provides a facile method for real-time detection of benzaldehyde. Meanwhile 1 also exhibits highly selective and sensitive sensing for Cu2+ over other cations with high quenching efficiency Ksv value 1.15*104L.mol-1. As far as we know, 1 represents the first example of alkaline earth-transition hetero-metallic Ba-Cd micro-porous coordination framework as bi functional luminescent probes for Cu2+ and benzaldehyde.

AB - The removal of nutrients by Scenedesmus sp. in a high-rate algal pond, and subsequent algal separation by coagulation-flocculation or flotation with ozone to recover biomolecules, were evaluated. Cultivation of Scenedesmus sp. in wastewater resulted in complete NH3-H removal, plus 93% total nitrogen and 61% orthophosphate removals. Ozone-flotation obtained better water quality results than coagulation-flocculation for most parameters (NH3-N, NTK, nitrate and nitrite) except orthophosphate. Ozone-flotation, also produced the highest recovery of lipids, carbohydrates and proteins which were 0.32 +/- 0.03, 0.33 +/- 0.025 and 0.58 +/- 0.014 mg/mg of biomass, respectively. In contrast, there was a low lipid extraction of 0.21 mg of lipids/mg of biomass and 0.12-0.23 mg of protein/mg of biomass in the coagulation-flocculation process. In terms of biomolecule recovery and water quality, ozone showed better results than coagulation-flocculation. PMID- 29574314 TI - Correlation between pyrolysis behaviors of the components and the overall pyrolysates from pulping spent liquor. AB - The pyrolysis behaviors of the three major organic components of eucalyptus alkaline peroxide mechanical pulping (APMP) spent liquor including alkali lignin (AL), lignin-carbohydrate complexes (LCC), and polysaccharide (PLS) were studied with emphasis on the effect and contributions of components on the overall pyrolysates of APMP spent liquor solid (ASLS). Profound differences on product properties from each component pyrolysis were illustrated. The results indicated that the bio-oil during ASLS pyrolysis was mainly attributed to AL, while the bio gas and char were mostly affected by PLS. Small molecule hydrocarbons released during ASLS pyrolysis mainly came from AL and LCC, and CO and CO2 mainly produced from PLS. As for bio-oils, AL generated the largest proportion of monomeric phenols and aromatic hydrocarbons (AHs), while PLS and LCC mainly contributed to the production of ketones, furans and acids. The correlation shown here is of interest for further studies on pulping spent liquor grading utilization. PMID- 29574315 TI - Application of alpha-amylase as a novel biodemulsifier for destabilizing amphiphilic polymer-flooding produced liquid treatment. AB - The performance and de-emulsification mechanism of alpha-amylase, a novel environmental friendly biodemulsifier in petroleum industry, was investigated at room temperature. The effects of alpha-amylase on the viscosity of amphiphilic polymer solution and de-emulsification rate were studied by changing the concentration of alpha-amylase, temperature and salinity. Polymer molecular weight, Zeta potential, interfacial film strength and interfacial tension were measured to investigate the de-emulsification mechanism of alpha-amylase. The results show that alpha-amylase is an efficient biodemulsifier to increase the de emulsification rate of amphiphilic polymer emulsions. Hydrolysis of alpha-amylase to amphiphilic polymers destroys the structure of the amphiphilic polymer, thereby reduces the viscosity and the interfacial film strength of the system. Once de-emulsification is completed, the lower layer, i.e. the emulsified layer, will be clear. Thus, alpha-amylase can be applied as an effective de-emulsifier for amphiphilic polymer-stabilized O/W emulsion. PMID- 29574316 TI - Enhancing the robustness of microbial fuel cell sensor for continuous copper(II) detection against organic strength fluctuations by acetate and glucose addition. AB - Microbial fuel cell sensors have shown great promise for continuous monitoring of toxic substances in wastewater, but a persistent problem is the signal interferences due to fluctuations in organic strength. An approach to eliminate the interferences is to saturate the sensor with an added organic substrate. In this study, signal stabilization using acetate and glucose addition (150, 300 and 500 mg COD/L) to domestic wastewater was examined. Addition of acetate (500 mg COD/L) gave the best performance, increasing the robustness of the sensor by reducing signal interference (decrease in baseline current) from 65% to 15% for a sudden 75% decrease in organic strength. The sensor sensitivity remained unchanged at current drop of 0.16%/(mg/L Cu(II)) for a toxicity event (300 mg/L Cu(II)). Addition of acetate (300 mg COD/L) and glucose (150, 300 and 500 mg COD/L) also resulted in increased robustness but led to a reduced sensitivity to Cu(II). PMID- 29574317 TI - Enhancement of TCE removal by a static magnetic field in a fungal biotrickling filter. AB - A fungal biotrickling filter (BTF) was employed to treat trichloroethylene (TCE) gas under different magnetic field intensities (MFIs). When the TCE inlet concentrations were approximately 370, 500-900, and 1000 mg/m3, the removal performances followed the order: MFI 20.0 mT > MFI 60.0 mT > MFI 80.0 mT > MFI 0 mT. In particular, at a TCE inlet concentration of 1000 mg/m3, MFI 20.0 mT was significantly better than MFI 0 mT performance. The corresponding removal efficiencies and maximum elimination capacities were 52.9%, 4854.1 mg/m3 h and 39.4%, 3594.8 mg/m3 h, respectively. BTF was shut down completely for 7 days and rapidly recovered in 6-10 days. High-throughput sequencing indicated that MF significantly affected the fungal community and significantly improved the relative abundance of the phylum Ascomycota, achieving the highest abundance of Ascomycota at MFI 20.0. These results indicated that a lower MFI can efficiently improve TCE removal performance in a fungal BTF. PMID- 29574318 TI - R1 dispersion contrast at high field with fast field-cycling MRI. AB - Contrast agents with a strong R1 dispersion have been shown to be effective in generating target-specific contrast in MRI. The utilization of this R1 field dependence requires the adaptation of an MRI scanner for fast field-cycling (FFC). Here, we present the first implementation and validation of FFC-MRI at a clinical field strength of 3 T. A field-cycling range of +/-100 mT around the nominal B0 field was realized by inserting an additional insert coil into an otherwise conventional MRI system. System validation was successfully performed with selected iron oxide magnetic nanoparticles and comparison to FFC-NMR relaxometry measurements. Furthermore, we show proof-of-principle R1 dispersion imaging and demonstrate the capability of generating R1 dispersion contrast at high field with suppressed background signal. With the presented ready-to-use hardware setup it is possible to investigate MRI contrast agents with a strong R1 dispersion at a field strength of 3 T. PMID- 29574319 TI - Nutrient enrichment during shrimp cultivation alters bacterioplankton assemblies and destroys community stability. AB - Intensive shrimp farming is generally accompanied by nutrient enrichment and gradual eutrophication, which impose major threats to shrimp culture ecosystems. However, little is known about how the bacterioplankton community in a rearing environment responds to increased eutrophication during shrimp culture processes. In this study, we used the MiSeq sequencing technique to explore the impacts of nutrient enrichment on the assembly and stability of the bacterioplankton community. Our results showed that magnitudes of the changes in the bacterioplankton community compositions (BCCs) and diversity were closely associated with eutrophication level. Moreover, a phylogenetic-based mean nearest taxon distance (MNTD) analysis revealed that increased eutrophication significantly (P < 0.01) changed the bacterioplankton ecological processes from deterministic to stochastic. A structural equation model showed that eutrophication indicators affected the BCCs either directly by controlling resources or indirectly by modifying other environmental variables of the shrimp ponds in complex pathways. Furthermore, association network comparisons revealed that nutrient enrichment increased the complexity of interspecies interactions and the proportion of cooperative interactions and decreased the proportion of generalists, which suggest that nutrient enrichment destroyed the community stability. These findings suggest that minimizing nutrient pollution, especially at the end of cultivation, could be an important management tool for establishing a microbially mature water system. PMID- 29574320 TI - Sulfate facilitates cadmium accumulation in leaves of Vicia faba L. at flowering stage. AB - Cadmium (Cd) is a toxic element, and is prevalent all over the world because of industrialization, mining, sewage sludge, or pesticide supply. Sulfur deficiency is also a frequent problem faced in agriculture. To date, information relating to effects of sulfate on Cd toxicity is still limited. To elucidate how sulfate affects Cd accumulation in faba bean, subcellular accumulation of Cd in leaves consisting of apoplastic washing fluid, symplastic fluid and the cell wall under deficient, sufficient and excess sulfate treatments were investigated in the present study. By using stable isotope of Cd (106Cd), we also traced Cd accumulation in young leaves at flowering stage from early and newly uptake of Cd in the same plants as affected by sulfate. We found that excess sulfate supply significantly increased newly uptake of Cd without affecting early uptake of Cd when compared with sufficient sulfate treatment, which resulted in enhanced total Cd in leaves by excess sulfate. Since newly uptake of Cd in leaves was from root uptake directly, we conclude that excess sulfate supply enhanced Cd originated from root uptake directly rather than re-translocation from old leaves, which is related to increased Cd accumulation in young leaves of faba bean. Subcellular analysis showed that the enhanced Cd by excess sulfate addition was a consequence of enhanced Cd in cell walls, while Cd accumulation in the apoplastic washing fluid and symplastic fluid were unchanged. The increased Cd by excess sulfate supply might be related to increased proportion of Cd speciation CdSO40 in the growth medium because of faster diffusion of CdSO40 than Cd2+. To test whether macronutrients, micronutrients, sulfate and non-protein thiol involved in cell wall-Cd accumulation as affected by sulfate, correlations of subcellular Cd with subcellular macronutrients, micronutrients, sulfate, and non-protein thiol were analyzed. We found that cell wall-Cd was negatively correlated with K and Ca concentrations, whereas cell wall-Cd was positively correlated with Cu and symplastic non-protein thiol concentrations. However, when compared with sufficient sulfate, excess sulfate decreased K concentration and increased symplastic non-protein thiol concentration without changing Ca and Cu concentrations. Based on those results, reduction of K concentration and enhancement of symplastic non-protein thiol concentration by sulfate supply might be a reason for increase of cell wall-Cd concentration. Taken together, increased Cd in cell walls of leaves by sulfate supply contributes to enhance Cd accumulation. PMID- 29574321 TI - Gold nanoparticles/4-aminothiophenol interfaces for direct electron transfer of horseradish peroxidase: Enzymatic orientation and modulation of sensitivity towards hydrogen peroxide detection. AB - Hydrogen peroxide electrochemical detection by horseradish peroxidase has been widely studied. The use of gold nanoparticles to prepare electrode/enzyme bioconjugates has attracted attention due to their catalytic properties. In this work, it is reported the use of gold nanoparticles and 4-aminothiophenol as a scaffold to obtain a suitable matrix for enzyme bioconjugation with horseradish peroxidase. A critical factor in biosensors design and development is the enzymatic electrochemical activity understanding. Comparison of voltammetric studies of the heme prosthetic group showed a reversible electrochemical behavior when the enzymes were immobilized in a well-dispersed gold deposit; on the other hand, a discrete redox response was observed on a randomly deposited gold electrode. These results show that the distance between enzymes is essential. Hydrogen peroxide catalysis and the enzymatic behavior were analyzed considering two types of nanoparticles dispositions. The catalytic behavior observed in the well-dispersed nanoparticles configuration suggests a preserved enzyme folding, a decrease of steric impediments, and appears to be a better immobilization strategy. In contrast, the randomly electrodeposited gold electrode decreased the enzyme orientation and the electrochemical activity. The advantages of this methodology are the electrode fabrication affordable cost and the enzymatic direct electron transfer response improvement. PMID- 29574322 TI - Expressional changes in stemness markers post electrochemotherapy in pancreatic cancer cells. AB - Pancreatic cancer is one of the most lethal cancers with high metastatic potential and strong chemoresistance. The capability of a tumor to grow and propagate is dependent on a small subset of cells within a tumor, termed cancer stem cells. Cancer stem cells exhibit great tumorigenicity and are closely correlated with drug resistance and tumor recurrence. The aim of our study was to illustrate electrochemotherapy as an effective treatment for pancreatic cancer along with the expression change in stemness genes (Nanog, Sox2 and Oct3/4) in pancreatic cancer cells post electrochemotherapy with bleomycin, cisplatin and oxaliplatin. Our results showed the enhanced expression of Nanog and decreased expression level of Oct3/4 after electrochemotherpy. We thus propose that these stemness markerS may have important roles in the initiation and/or recurrence of pancreatic cancer, and consequently may serve as important molecular diagnostics and/or therapeutic targets for the development of novel treatment strategies in pancreatic cancer patients. In conclusion, targeting these stemness factors could potentially improve electrochemotherapy as a treatment and preventing recurrence. PMID- 29574323 TI - Deep insights into the mode of ATP-binding mechanism in Zebrafish cyclin dependent protein kinase-like 1 (zCDKL1): A molecular dynamics approach. AB - In eukaryotes, the serine/threonine kinases (STKs) belonging to cyclin-dependent protein kinases (CDKs) play significant role in control of cell division and curb transcription in response to several extra and intra-cellular signals indispensable for enzymatic activity. The zebrafish cyclin-dependent protein kinase-like 1 protein (zCDKL1) shares a high degree of sequence and structural similarity with mammalian orthologs and express in brain, ovary, testis, and low levels in other tissues. Regardless of its importance in the developmental process, the structure, function and mode of ATP recognition have not been investigated yet due to lack of experimental data. Henceforth, to gain atomistic insights in to the structural dynamics and mode of ATP binding, a series of computational techniques involving theoretical modeling, docking, molecular dynamics (MD) simulations and MM/PBSA binding free energies were employed. The modeled bi-lobed zCDKL1 shares a high degree of secondary structure topology with human orthologs where ATP prefers to lie in the central cavity of the bi-lobed catalytic domain enclosed by strong hydrogen bonding, electrostatic and hydrophobic contacts. Long range MD simulation portrayed that catalytic domain of zCDKL1 to be highly rigid in nature as compared to the complex (zCDKL1-ATP) form. Comparative analysis with its orthologs revealed that conserved amino acids i.e., Ile10, Gly11, Glu12, Val18, Arg31, Phe80, Glu 130, Cys143 and Asp144 were crucial for ATP binding mechanism, which needs further investigation for legitimacy. MM/PBSA method revealed that van der Waals, electrostatic and polar solvation energy mostly contributes towards negative free energy. The implications of ATP binding mechanism inferred through these structural bioinformatics approaches will help in understanding the catalytic mechanisms of important STKs in eukaryotic system. PMID- 29574324 TI - Transcript analyses of ethylene pathway genes during ripening of Chinese jujube fruit. AB - The fruit of Chinese jujube (Ziziphus jujuba Mill.) is immensely popular worldwide, while its fleshy fruit has a very short shelf life and suffers serious postharvest damage. The fruit has been controversially classified as non climacteric, though the mechanisms underlying its ripening behavior, particularly the role of ethylene, have remained unclear. In this study, low and stable ethylene production was detected during ripening of Z. jujuba 'Dongzao' fruit, with production increasing at the full maturity stage. To determine potential ripening behavior, the fruit of five cultivars were harvested at the white mature stage, and all exhibited a first decreasing and then moderately increasing respiration rate without concomitant climacteric-like ethylene production during shelf storage. Treatment with 1.0 MUL L-1 1-methylcyclopropene (1-MCP) inhibited respiration and ethylene production in white mature fruit, though the effects of 100 MUL L-1 exogenous ethylene were not significant. The transcript levels of genes involved in ethylene biosynthesis, perception, and signal transduction were not elevated during fruit-ripening onset but substantially increased at the full red ripening stage. Moreover, expression of genes controlling ethylene biosynthesis and perception mainly occurred in an auto-inhibited System-1-like manner, but signaling pathway genes were minimally affected by exogenous ethylene or 1-MCP. These results show that the ripening of Chinese jujube is non climacteric. The basal level of ethylene likely plays a minor role in ripening regulation but is necessary to maintain normal ripening. This study elucidates the effects of ethylene on jujube fruit ripening, characterizing the ripening of this fruit as non-climacteric, and also provides strategies for the improvement and maintenance of fruit quality and the extension of shelf life during postharvest storage. PMID- 29574325 TI - A disturbed auxin signaling affects adventitious root outgrowth in Solanum dulcamara under complete submergence. AB - Flooding negatively affects the growth and even survival of most terrestrial plants. Upon flooding, the excess water quickly decreases the gas exchange between atmosphere and the submerged plant tissues, which leads to oxygen deficiency resulting in a plant cell energy crisis, and eventually plant death. Solanum dulcamara survives flooding by producing aerenchymatous adventitious roots (ARs) from pre-formed primordia on the stem, which replace the original flood-sensitive root system. However, we found that under complete submergence, AR outgrowth was impaired in S. dulcamara. In the present work, we tried to elucidate the mechanisms behind this phenomenon in particular the involvement of the phytohormones auxin, abscisic acid and jasmonic acid. Abscisic acid (ABA) is a negative regulator of AR outgrowth, but surprisingly the ABA content and signaling were decreased to a similar extent under both partial and complete submergence, suggesting that ABA might not be responsible for the difference in AR outgrowth. Auxin, which is necessary for AR outgrowth, was at similar concentrations in either partially or completely submerged primordia, but complete submergence resulted in a decrease of auxin signaling in the primordia. Application of 1-naphthaleneacetic acid (NAA) to completely submerged plants restored AR outgrowth, implying that auxin response in the rooting tissues of completely submerged plants was reduced. Furthermore, jasmonic acid (JA) concentrations did not differ between partial and complete submergence. To conclude, a disruption in the auxin signaling within S. dulcamara AR primordia may result in the abortion of AR outgrowth under complete submergence. PMID- 29574326 TI - Promoter analysis and functional implications of the selenium binding protein (SBP) gene family in Arabidopsis thaliana. AB - Selenium Betainding Protein (SBP, originally termed SBP56) was identified in mouse liver as a cytosolic protein that could bind radioactive selenium. SBPs are highly conserved proteins present in a wide array of species across all kingdoms and are likely to be involved in selenium metabolism. In Arabidopsis, the selenium binding protein (SBP) gene family comprises three genes (AtSBP1, AtSBP2 and AtSBP3). AtSBP1 and AtSBP2 are clustered in a head-to-tail arrangement on chromosome IV, while AtSBP3 is located on chromosome III. In this work, we studied the promoter activity of the Arabidopsis SBP genes, determined their tissue specificity and showed that they are differentially regulated by sodium selenite and sodium selenate. All three SBP genes are upregulated in response to externally applied selenium compounds and the antioxidant NAC selectively downregulates SBP2. Although the effect on SBP2 levels was the most prominent, in all cases, the concurrent exposure of plants to selenite and the antioxidant supressed the expression of the SBP genes. We provide evidence that (at least) SBP1 expression is tightly linked to detoxification processes related to oxidative stress, since it is downregulated in the presence of NAC in selenium treated plants. Furthermore, our results suggest that SBP genes may participate in the mechanisms that sense redox imbalance. PMID- 29574327 TI - Clinical Significance of Peripheral Blood PCA3 Gene Expression in Early Diagnosis of Prostate Cancer. AB - Prostate cancer antigen 3 (PCA3) is one of the most promising genes currently investigated as a specific tumor biomarker for the diagnosis of prostate cancer. The purpose of this study was to investigate PCA3 gene expression in peripheral blood of prostate cancer (PCa) and benign prostate hyperplasia (BPH), and further to assess its clinical significance. We determined the copies of PCA3 mRNA in peripheral blood of PCa and BPH from 115 samples (PCa, n=78; BPH, n=37) using a quantitative reverse transcriptase-quantitative polymerase chain reaction (RT qPCR) with TaqMan assay. The sensitivity and specificity of PCA3 for the diagnosis of prostate cancer was compared with that of prostate-specific antigen (PSA) by receiver operating characteristic (ROC) curve analysis. To evaluate the association between PCA mRNA and disease progression, we analyzed PCA3 levels in connection with Gleason score and TNM stage of PCa. The clinical data revealed that expression of PCA3 gene was significantly higher in PCa than in BPH. Moreover, PCA3 mRNA was significantly higher in PCa patients with a Gleason score >=8 than in those with a Gleason score <=7 (P<.01). The results showed that the area under the curve (AUC) was 0.790, 0.606, and 0.620 for the copy number of PCA3, PSA level, and significantly free PSA (fPSA) level, respectively. Increased PCA3 in peripheral blood is correlated with PCa, and the detection of PCA3 may significantly reduce adverse screening outcomes. PCA3 gene expression in peripheral blood had a promising clinical application in the early diagnosis of PCa. PMID- 29574328 TI - The Modifying Effect of a Functional Variant at the miRNA Binding Site in E2F1 Gene on Recurrence of Oropharyngeal Cancer Patients with Definitive Radiotherapy. AB - Human papillomavirus (HPV) activates E2F1-driven transcription via the E7-RB-E2F1 pathway. A polymorphism in the 3' UTR of E2F1 gene may disrupt a binding site for miRNA and may affect its transcription level, thus modifying the susceptibility to radiotherapy and outcomes through this pathway. We evaluated the association of a polymorphism at the 3'UTR miRNA binding site of E2F1 gene (rs3213180) with risk of recurrence of SCCOP in a cohort of 1008 patients. Log-rank test and univariate and multivariable Cox models were used to evaluate the associations. Compared with patients with E2F1-rs3213180 GG homozygous genotype, the patients with E2F1-rs3213180GC+CC variant genotypes had significantly better disease-free survival (log-rank P<.001) and decreased risk of SCCOP recurrence (HR, 0.4, 95% CI, 0.3-0.5) after multivariable adjustment. Furthermore, among patients with HPV16-positive tumors, the patients with E2F1-rs3213180 GC+CC variant genotypes had significantly better disease-free survival rates (log-rank P<.001) and lower recurrence risk than those with E2F1-rs3213180 GG homozygous genotype (HR, 0.2, 95% CI, 0.1-0.4). Our findings suggest that E2F1-rs3213180 polymorphism may modulate the risk of recurrence in SCCOP patients, particularly for patients with HPV16-positive tumors of SCCOP. However, future larger population and functional studies are warranted to validate these results. PMID- 29574329 TI - In silico modelling of azole derivatives with tyrosinase inhibition ability: Application of the models for activity prediction of new compounds. AB - Tyrosinase is a metal containing multifunctional enzymes found in animals, fruits and vegetables and constitutes the primary cause for diseases resulting from overproduction of melanin as well as for browning of fruits. Inhibitors of the enzyme have thus gained increased importance in food and cosmetic industry. In the present work, a group of azole derivatives with tyrosinase inhibitory activity were explored to analyse the prime structural attributes of the potent inhibitors. In silico models have been developed in order to have a close insight regarding features of the molecular fragments that may affect the activity of the molecules conducively. The biological pharmacophore of the inhibitors that accounts for their interaction with the tyrosinase enzyme has been ascertained based on the development of a 3D pharmacophore model. The models thus developed were subsequently utilised for screening a set of compounds that were previously synthesised in-house and were reported to possess antioxidant activity. The final selection of active molecules in the screening process was done based on the docking interactions of the molecules with the tyrosinase enzyme and assessment of their degree of binding to the protein. Thus the developed models have been successfully utilised for identifying active compounds from a series of untested molecules. PMID- 29574331 TI - Butyrate from pectin fermentation inhibits intestinal cholesterol absorption and attenuates atherosclerosis in apolipoprotein E-deficient mice. AB - Short-chain fatty acids (SCFAs), the major products of dietary fiber fermentation by intestinal microflora, exert beneficial effects on pathogenesis of multiple metabolic diseases. The aim of this study was to determine whether SCFAs from fermentation of pectin (PE), a soluble dietary fiber, prevent the development of atherosclerosis in apolipoprotein E-deficient (apoE-/-) mice. Male apoE-/- mice (8-week-old) were fed a high-fat, high-cholesterol diet (HCD; 21% wt/wt fat, 0.15% wt/wt cholesterol) or HCD supplemented with 20% wt/wt PE (HCD+PE) alone or with antibiotics (HCD+PE + A) in drinking water for 12 weeks. Serum lipids and SCFAs concentrations, atherosclerotic lesion area, and intestinal morphology and function were measured. Caco-2 cells were treated with SCFAs to determine whether they affected the expression of genes involved in cholesterol absorption. HCD+PE treated mice exhibited decreased serum total and low-density lipoprotein cholesterol, and reduced atherosclerotic lesion area compared with HCD mice. These beneficial effects of PE were not observed in the HCD+PE+A group. Incubation of Caco-2 cells with butyrate, but not acetate and propionate, down regulated the expression of Niemann-Pick C1-Like 1 but up-regulated the ATP binding cassette transporters G5 and G8 (ABCG5 and G8) at the mRNA level. Butyrate treatment also increased transcriptional activity of liver X receptor in Caco-2 cells. Our data suggest that butyrate from PE intestinal fermentation protects mice from the progression of diet-induced atherosclerosis in apoE-/- mice. These findings suggest a novel mechanism by which dietary fiber may prevent the development of atherosclerosis. PMID- 29574330 TI - Rational engineering of synthetic microbial systems: from single cells to consortia. AB - One promise of synthetic biology is to provide solutions for biomedical and industrial problems by rational design of added functionality in living systems. Microbes are at the forefront of this biological engineering endeavor due to their general ease of handling and their relevance in many potential applications from fermentation to therapeutics. In recent years, the field has witnessed an explosion of novel regulatory tools, from synthetic orthogonal transcription factors to posttranslational mechanisms for increased control over the behavior of synthetic circuits. Tool development has been paralleled by the discovery of principles that enable increased modularity and the management of host-circuit interactions. Engineered cell-to-cell communication bridges the scales from intracellular to population-level coordination. These developments facilitate the translation of more than a decade of circuit design into applications. PMID- 29574332 TI - Fungal community, Fusarium head blight complex and secondary metabolites associated with malting barley grains harvested in Umbria, central Italy. AB - In recent years, due to the negative impact of toxigenic mycobiota and of the accumulation of their secondary metabolites in malting barley grains, monitoring the evolution of fungal communities in a certain cultivation area as well as detecting the different mycotoxins present in the raw material prior to malting and brewing processes have become increasingly important. In this study, a survey was carried out on malting barley samples collected after their harvest in the Umbria region (central Italy). Samples were analyzed to determine the composition of the fungal community, to identify the isolated Fusarium species, to quantify fungal secondary metabolites in the grains and to characterize the in vitro mycotoxigenic profile of a subset of the isolated Fusarium strains. The fungal community of barley grains was mainly composed of microorganisms belonging to the genus Alternaria (77%), followed by those belonging to the genus Fusarium (27%). The Fusarium head blight (FHB) complex was represented by nine species with the predominance of Fusarium poae (37%), followed by Fusarium avenaceum (23%), Fusarium graminearum (22%) and Fusarium tricinctum (7%). Secondary metabolites biosynthesized by Alternaria and Fusarium species were present in the analyzed grains. Among those biosynthesized by Fusarium species, nivalenol and enniatins were the most prevalent ones. Type A trichothecenes (T-2 and HT-2 toxins) as well as beauvericin were also present with a high incidence. Conversely, the number of samples contaminated with deoxynivalenol was low. Conjugated forms, such as deoxynivalenol-3-glucoside and HT-2-glucoside, were detected for the first time in malting barley grains cultivated in the surveyed area. In addition, strains of F. avenaceum and F. tricinctum showed the ability to biosynthesize in vitro high concentrations of enniatins. The analysis of fungal secondary metabolites, both in the grains and in vitro, revealed also the presence of other compounds, for which further investigations will be required. The combination of microbiological analyses, of molecular biology assays and of multi-mycotoxin screening shed light on the complexity of the fungal community and its secondary metabolites released in malting barley. PMID- 29574333 TI - Isolation and characterization of microorganisms and volatiles associated with Moroccan saffron during different processing treatments. AB - Saffron may be spoiled by a variety of microorganisms during cultivation, harvesting, and post harvesting. As saffron can be dried and stored in different ways, this preliminary study explored the natural microbiota present in Moroccan saffron when subjected to different drying techniques. An analysis of the carotenoid-derived volatiles present in the saffron was also carried out. The culturable microbiota of the saffron samples dried using different methods, namely in the shade (also called natural), in the sun, or in the oven, were studied using classical and molecular approaches. The effect of the drying methods on head-space chemical volatiles was also determined. Eighty-two isolates grown in the different culture media were chosen from the colonies, and genotype analysis grouped the microorganisms into 58 clusters, revealing a wide diversity. Out of the 82 isolates, 75 belonged to the Bacillaceae family. The other isolates were distributed within the Dietziaceae, Paenibacillaceae and Carnobacteriaceae families. The dominant species was Bacillus simplex, which was detected in all samples, regardless of the drying method used. Lysinibacillus macroides was dominant in the sun-dried saffron. No pathogens were isolated, but an isolate belonging to Dietzia maris, a potential human pathogenic species, was detected. The biodiversity indexes were linked to the drying method and generally decreased as the intensity of the treatment increased. The results of this preliminary work show that the different drying methods strongly influenced the microbiota and affect the saffron volatile profile. Further analysis will be needed to determine possible effects of selected microbiota on saffron volatiles. PMID- 29574334 TI - Immuno-oncology in head and neck squamous cell cancers: News from clinical trials, emerging predictive factors and unmet needs. AB - According to the new determinants of cancer immunity, head and neck squamous cell cancer (HNSCC) has to be considered as an immunogenic tumor for the relatively high number of somatic mutations giving rise to neoantigens recognized by T cell. HNSCC develop at a significant rate despite the antitumoral immune response indicating the existence of effective escape mechanisms. The lack of antigen presentation or co-stimulatory molecules required and immunosuppressive phenomena established by the tumor or the host microenvironment impair immune-mediated recognition and cancer control. Echoing the success in melanoma and NSCLC, strategies aimed to reverse this process and enhance the antitumor immunity are rapidly developing in HNSCC, as monotherapies, multidrug immunotherapies or associations with well-recognized treatments, like radiation and systemic therapies. According to the first published data, immunotherapy has shown promising results in the management of recurrent and metastatic (r/m) HNSCC. Anti PD-1 blockers have been recently approved by US and EU regulatory agencies in this setting. The encouraging results in r/m HNSCC prompted the incorporation of this approach also in the treatment of locally advanced disease. However, the strategies for the rational and evidence-based combinations to maximize clinical benefit are only starting to emerge. In this view, knowing in depth the specific properties of HNSCC and the underlying immunological conditions of the bearing hosts is an essential step. The role of immune system in the development and the management of HNSCC, the main mechanisms of tumor escape and the most recent results from clinical trials will be discussed herein.

Previous reports have shown that AXL, a transmembrane receptor tyrosine kinase protein, is essential for ZIKV infection of mammalian cells, but this remains controversial. Here, we have assessed the involvement of AXL in the ability of ZIKV to infect mammalian cells, and also the requirement for endocytosis and acidic pH. We demonstrated that AXL is essential for ZIKV infection of human fibroblast cell line HT1080 as the targeted deletion of the gene for AXL in HT1080 cells made them no longer susceptible to ZIKV infection. Our results also showed that infection was prevented by lysosomotropic agents such as ammonium chloride, chloroquine and bafilomycin A1, which neutralize the normally acidic pH of endosomal compartments. Infection by ZIKV was also blocked by chlorpromazine, indicating a requirement for clathrin-mediated endocytosis. Taken together, our findings suggest that AXL most likely serves as an attachment factor for ZIKV on the cell surface, and that productive infection requires endocytosis and delivery of the virus to acidified intracellular compartments.

AB - The development of influenza vaccines that can provide broad protection against all drifted seasonal virus variants, zoonotic infections and emerging pandemic strains, has been a priority for two decades. Here we propose a strategy of inducing broadly-reactive anti-stalk antibody by sequential immunizations with live attenuated influenza vaccines (LAIVs) expressing chimeric HAs (cHAs). These vaccines are designed to contain identical hemagglutinin stalk domains from H1N1 virus but antigenically unrelated globular head domains from avian influenza virus subtypes H5, H8 and H9. Mouse experiments demonstrated enhanced cross protection of cHA-containing LAIVs compared to the relevant vaccine viruses expressing natural HAs, and this enhanced protection was driven by stalk-HA reactive IgG antibodies. The establishment of fully functional cross-protective immunity after two doses of cHA LAIV vaccination in naive animals suggests that a similar effect might be expected after a single cHA LAIV dose in primed individuals, or after two to three doses in naive children.

AB - BACKGROUND: Transport-related air and noise pollution, exposures linked to adverse health outcomes, varies within cities potentially resulting in exposure inequalities. Relatively little is known regarding inequalities in personal exposure to air pollution or transport-related noise. OBJECTIVES: Our objectives were to quantify socioeconomic and ethnic inequalities in London in 1) air pollution exposure at residence compared to personal exposure; and 2) transport related noise at residence from different sources. METHODS: We used individual level data from the London Travel Demand Survey (n = 45,079) between 2006 and 2010. We modeled residential (CMAQ-urban) and personal (London Hybrid Exposure Model) particulate matter <2.5 MUm and nitrogen dioxide (NO2), road-traffic noise at residence (TRANEX) and identified those within 50 dB noise contours of railways and Heathrow airport. We analyzed relationships between household income, area-level income deprivation and ethnicity with air and noise pollution using quantile and logistic regression. RESULTS: We observed inverse patterns in inequalities in air pollution when estimated at residence versus personal exposure with respect to household income (categorical, 8 groups). Compared to the lowest income group (L75,000) had lower residential NO2 (-1.3 (95% CI -2.1, -0.6) MUg/m3 in the 95th exposure quantile) but higher personal NO2 exposure (1.9 (95% CI 1.6, 2.3) MUg/m3 in the 95th quantile), which was driven largely by transport mode and duration. Inequalities in residential exposure to NO2 with respect to area-level deprivation were larger at lower exposure quantiles (e.g. estimate for NO2 5.1 (95% CI 4.6, 5.5) at quantile 0.15 versus 1.9 (95% CI 1.1, 2.6) at quantile 0.95), reflecting low deprivation, high residential NO2 areas in the city centre. Air pollution exposure at residence consistently overestimated personal exposure; this overestimation varied with age, household income, and area-level income deprivation. Inequalities in road traffic noise were generally small. In logistic regression models, the odds of living within a 50 dB contour of aircraft noise were highest in individuals with the highest household income, white ethnicity, and with the lowest area-level income deprivation. Odds of living within a 50 dB contour of rail noise were 19% (95% CI 3, 37) higher for black compared to white individuals. CONCLUSIONS: Socioeconomic inequalities in air pollution exposure were different for modeled residential versus personal exposure, which has important implications for environmental justice and confounding in epidemiology studies. Exposure misclassification was dependent on several factors related to health, a potential source of bias in epidemiological studies. Quantile regression revealed that socioeconomic and ethnic inequalities in air pollution are often not uniform across the exposure distribution.

AB - Methylmercury can readily cross the human placental barrier and the blood-brain barrier and cause damage to the vulnerable developing brains of the fetus and infants. Most of the previous studies on the maternal transfer of methylmercury to the next generation have focused on the prenatal period. In this study, human physiologically based pharmacokinetic (PBPK) models of methylmercury were established for breastfeeding mothers and suckling infants based on the existing model prototypes of previous studies. Relevant parameters of the models were modified, and the validation was conducted based on measured data in North China. The models could effectively describe the human lactational transfer of methylmercury, including the time-dependent methylmercury levels in different tissues and organs of the breastfeeding mothers and suckling infants. The results indicated that 77.2% and 14.9% of methylmercury were excreted via hair and breast milk, respectively, from breastfeeding mothers during the first year after delivery. Meanwhile, 79.2% was excreted from the suckling infants during the first year after delivery via hair. Lactational transfer of methylmercury was considered an important pathway of methylmercury exposure for the breastfeeding infants, which accounted for approximately 80% of the accumulated adverse impacts at the early stages of human development. PMID- 29574340 TI - Assessing frailty in the intensive care unit: A reliability and validity study. AB - PURPOSE: To describe pre-ICU frailty in critically ill patients using the Clinical Frailty Scale (CFS). METHODS: We included patients >=18years admitted to 2 ICUs in Hamilton, Canada. The ICU Research Coordinator (RC) generated 3 CFS scores using: 1) chart review, 2) family interview, 3) patient interview. Subsequently, an overall impression was captured in a final score. Mean differences were calculated to assess the RC intra-rater reliability and inter rater reliability of chart reviews by the RC, Occupational Therapist (OT), and Geriatrics Resident (GR). Scores were also compared between younger and older patients. We also analyzed the relationship between CFS scores and mortality. RESULTS: We prospectively enrolled 150 patients (mean age 63.8 [SD 15.3] years, APACHE II score 21 [SD 7.3]). CFS were similar between RC, OT, and GR chart reviews (p>0.05 for all comparisons). There was no difference between RC chart review and RC final score, or between RC patient interview and RC final score. Scores following the RC family interview and the RC final score were significantly different (-0.24, 95% CI -0.38, -0.09, p<0.01). Each 1-point increase in the final CFS scored by the RC was weakly associated with ICU mortality (odds ratio 1.18, 95% CI 0.84-1.66, p=0.33), and hospital mortality (OR 1.19, 95% CI 0.89, -1.59, p=0.24). CONCLUSIONS: CFS scores can be generated using medical chart review and can be reliably completed by ICU clinicians and research staff. PMID- 29574339 TI - Indoor black carbon of outdoor origin and oxidative stress biomarkers in patients with chronic obstructive pulmonary disease. AB - OBJECTIVES: We assessed relationships between indoor black carbon (BC) exposure and urinary oxidative stress biomarkers, 8-hydroxy-2'-deoxyguanosine (8-OHdG) and malondialdehyde (MDA), in participants with chronic obstructive pulmonary disease (COPD). METHODS: Eighty-two participants completed in-home air sampling for one week prior to providing urine samples up to four times in a year. Weekly indoor and daily outdoor concentrations were used to estimate indoor daily lags and moving averages. There were no reported in-home BC sources, thus indoor levels closely represented outdoor BC infiltration. Mixed effects regression models with a random intercept for each participant were used to assess relationships between indoor BC and 8-OHdG and MDA, adjusting for age, race, BMI, diabetes, heart disease, season, time of urine collection, urine creatinine, and outdoor humidity and temperature. RESULTS: There were positive effects of BC on 8-OHdG and MDA, with the greatest effect the day before urine collection (6.9% increase; 95% CI 0.9-13.3%, per interquartile range: 0.22 MUg/m3) for 8-OHdG and 1 to 4 days before collection (8.3% increase; 95% CI 0.03-17.3% per IQR) for MDA. Results were similar in models adjusting for PM2.5 not associated with BC and NO2 (10.4% increase, 95% CI: 3.5-17.9 for 8-OHdG; 8.1% increase, 95% CI: -1.1-18.1 for MDA). Effects on 8-OHdG were greater in obese participants. CONCLUSIONS: We found positive associations between BC exposure and 8-OHdG and MDA, in which associations with 8-OHdG were stronger in obese participants. These results suggest that exposure to low levels of traffic-related pollution results in lipid peroxidation and oxidative DNA damage in individuals with COPD. PMID- 29574341 TI - Postural reconfiguration and cycle-to-cycle variability in patients with work related musculoskeletal disorders compared to healthy controls and in relation to pain emerging during a repetitive movement task. AB - BACKGROUND: Movement variability in sustained repetitive tasks is an important factor in the context of work-related musculoskeletal disorders. While a popular hypothesis suggests that movement variability can prevent overuse injuries, pain evolving during task execution may also cause variability. The aim of the current study was to investigate, first, differences in movement behavior between volunteers with and without work-related pain and, second, the influence of emerging pain on movement variability. METHODS: Upper-body 3D kinematics were collected as 22 subjects with musculoskeletal disorders and 19 healthy volunteers performed a bimanual repetitive tapping task with a self-chosen and a given rhythm. Three subgroups were formed within the patient group according to the level of pain the participants experienced during the task. Principal component analysis was applied to 30 joint angle coordinates to characterize in a combined analysis the movement variability associated with reconfigurations of the volunteers' postures and the cycle-to-cycle variability that occurred during the execution of the task. FINDINGS: Patients with no task-related pain showed lower cycle-to-cycle variability compared to healthy controls. Findings also indicated an increase in movement variability as pain emerged, manifesting both as frequent postural changes and large cycle-to-cycle variability. INTERPRETATION: The findings suggested a relationship between work-related musculoskeletal disorders and movement variability but further investigation is needed on this issue. Additionally, the findings provided clear evidence that pain increased motor variability. Postural reconfigurations and cycle-to-cycle variability should be considered jointly when investigating movement variability and musculoskeletal disorders. PMID- 29574342 TI - Three-dimensional kinematics of the cervical spine using an electromagnetic tracking device. Differences between healthy subjects and subjects with non specific neck pain and the effect of age. AB - BACKGROUND: A cross-sectional observational study of three-dimensional cervical kinematics in 35 non-specific neck pain patients and 100 asymptomatic controls. To compare qualitative and quantitative aspects of cervical kinematics between healthy subjects and subjects with non-specific neck pain and to determine the effect of age on cervical kinematics in healthy subjects. METHODS: Three dimensional kinematics of active lateral bending and flexion-extension of 35 patients and 100 controls were registered by means of an electromagnetic tracking system. The means of several kinematic parameters were compared using t-tests. In addition, we assessed the age-dependency of the three-dimensional kinematic parameters by stratifying the 100 control subjects in 6 age categories. FINDINGS: Comparison of the patient group with the control group reveals no statistically significant differences in qualitative and quantitative parameters. Analysis of the effect of age showed that the range of motion decreases significantly (p < 0.01) with increasing age. In lateral bending, the ratio between axial rotation and lateral bending increases significantly (p < 0.01) among older subjects. Differences in acceleration, jerk and polynomial fit are seen between the age categories, but are not significant. INTERPRETATION: This study demonstrates no significant differences in kinematic parameters between healthy subjects and subjects with non-specific neck pain. Healthy subjects in higher age categories demonstrate higher ratios of coupled movements and lower ranges of motion. Future research should focus on classifying patients with non-specific neck pain in order to gain a better insight on possible subgroup specific differences in kinematics. More studies on this subject are warranted. LEVEL OF EVIDENCE: 4. PMID- 29574344 TI - Current and future modalities of dynamic control in metabolic engineering. AB - Metabolic engineering aims to maximize production of valuable compounds using cells as biological catalysts. When incorporating engineered pathways into host organisms, an inherent conflict is presented between maintenance of cellular health and generation of products. This challenge has been addressed through two main modalities of dynamic control: decoupling growth from production via two phase fermentations and autoregulation of pathways to optimize product formation. However, dynamic control can offer even greater potential for metabolic engineering through open-loop and closed-loop control modalities of the production phase. Here we review recent applications of dynamic control strategies in metabolic engineering. We then explore the potential of integrating biosensors and computer-assisted feedback control as a promising future modality of dynamic control. PMID- 29574343 TI - Enhanced colloidal stability and protein resistance of layered double hydroxide nanoparticles with phosphonic acid-terminated PEG coating for drug delivery. AB - Conjugating nanoparticles with polyethylene glycol (PEG) is a useful strategy to improve the colloidal and biological stability of nanoparticles. However, studies on PEGylation of two-dimensional layered double hydroxide (LDH) nanoparticles are very limited. The present work reported two functionalization approaches to synthesize PEG-conjugated LDH nanoparticles by introducing phosphonic acid terminated PEG before and after LDH aging. The successful PEGylation was confirmed and suggested to be via electrostatic interaction and a ligand exchange process. Different functionalization approaches resulted in different binding types of PEG on/in LDH nanoparticles. The PEG coating maintained the dispersity of LDH nanoparticles in water and saline with the feeding mass ratio of 1:1. Further colloidal stability tests of PEGylated LDHs revealed that the PEGylated LDH dispersity was affected by the feeding mass ratio of PEG/LDH, the molar weight of PEG and anions intercalated in the LDHs. In a test to determine the extent of non-specific protein adsorption, the PEGylation was effective at resisting non-specific bovine serum albumin adsorption on LDH nanoparticles with both functionalization methods investigated. Moreover, PEGylated LDH nanoparticles had no effect on cell viability up to 500 ug/mL, and demonstrated enhanced cellular uptake in a SK-MEL-28 cell culture. The results in this work indicate that conjugating phosphonic acid-terminated PEG on LDH nanoparticles is a promising strategy to improve the colloidal and biological stability of LDHs for biomedical applications. PMID- 29574345 TI - Range of therapeutic metformin concentrations in clinical blood samples and comparison to a forensic case with death due to lactic acidosis. AB - Due to a lack of reference values for blood concentration of metformin in the literature, the forensic evaluation of metformin findings in blood samples is difficult. Interpretations with regard to the assessment of blood concentrations as well as an estimation of the ingested metformin amounts are often vague. Furthermore, post mortem evaluation of death due to lactic acidosis because of metformin is difficult since renal performance or lactate concentrations can not always reliably be determined after death. To describe a concentration range in clinical samples after chronic use of metformin, metformin serum concentrations were determined in serum samples of 95 diabetic patients receiving daily doses of 500mg-3000mg of metformin. The analyses of metformin was carried out using a validated high performance liquid chromatograph coupled to triple quadrupole mass spectrometry (LC-QQQ-MS). On average, metformin concentrations were 1846ng/mL (80% for all 3 devices. Ora-Check(r) had poor sensitivities (ketamine 36%, methamphetamine 63%, opiates 53%, cocaine 60%, THC 0%). DrugWipe(r) 6S showed good sensitivities in the methamphetamine (83%) and opiates (93%) tests but performed relatively poorly for ketamine (41%), cocaine (43%) and THC (22%). SalivaScreen(r) also demonstrated good sensitivities in the methamphetamine (83%) and opiates (100%) tests, and had the highest sensitivity for ketamine (76%) and cocaine (71%); however, it failed to detect any of the 28 THC-positive cases. The test completion rate (proportion of tests completed with quality control passed) were: 52% (Ora-Check(r)), 78% (SalivaScreen(r)) and 99% (DrugWipe(r) 6S). PMID- 29574347 TI - Authenticity assessment of banknotes using portable near infrared spectrometer and chemometrics. AB - Spectra recorded using a portable near infrared (NIR) spectrometer, Soft Independent Modeling of Class Analogy (SIMCA) and Linear Discriminant Analysis (LDA) associated to Successive Projections Algorithm (SPA) models were applied to identify counterfeit and authentic Brazilian Real (R$20, R$50 and R$100) banknotes, enabling a simple field analysis. NIR spectra (950-1650nm) were recorded from seven different areas of the banknotes (two with fluorescent ink, one over watermark, three with intaglio printing process and one over the serial numbers with typography printing). SIMCA and SPA-LDA models were built using 1st derivative preprocessed spectral data from one of the intaglio areas. For the SIMCA models, all authentic (300) banknotes were correctly classified and the counterfeits (227) were not classified. For the two classes SPA-LDA models (authentic and counterfeit currencies), all the test samples were correctly classified into their respective class. The number of selected variables by SPA varied from two to nineteen for R$20, R$50 and R$100 currencies. These results show that the use of the portable near-infrared with SIMCA or SPA-LDA models can be a completely effective, fast, and non-destructive way to identify authenticity of banknotes as well as permitting field analysis. PMID- 29574348 TI - Facial soft tissue thickness (FSTT) estimation models-And the strength of correlations between craniometric dimensions and FSTTs. AB - It has been speculated that craniometric dimensions can be used to improve estimations of facial soft tissue thickness (FSTT) in craniofacial identification. Subsequently, linear regression (LR) models have been published, but the practical utility of these models (lower errors than means) has never been tested/demonstrated. Using 71 living subjects measured by B-mode ultrasound, this study calculates and compares standard errors for previously published LR models and untrimmed FSTT means. Correlations between craniometric dimensions and FSTTs were calculated and regression model reproducibility examined by: generating new models using a 61 subject training set; and three-fold cross validation. Published regression models, applied to the above mentioned new individuals of this study, provided substantially worse estimates of ground truth FSTTs than untrimmed arithmetic means (mean Sest=4.0mm compared to 2.8mm, n=61 71). Correlations between craniometrics and FSTTs were generally small (mean of absolute values=0.17, raw interval=-0.24 to 0.48) and only two of 15 previously published LR models were reproducible (mr-mr' and g-g')-i.e., contained the same independent variable with no more than one other different independent variable entering the model. Under three-fold cross-validation (training sets of 40-41 individuals), no LR equation was reproduced across all three validation test runs. Basic craniometric dimensions do not appear to generally improve FSTT estimations and relationships between craniometric dimensions and FSTTs are much weaker and less reliable than previously thought. B-mode ultrasound data for adult Australians were pooled herein to provide larger sampled and updated FSTT statistics for this cohort (n=118-123). PMID- 29574349 TI - Fingermarks in blood: Mechanical models and the color of ridges. AB - This article treats fingermarks in blood on non-porous surfaces and addresses the question of "which came first": the fingermark or the blood. Three mechanical models were systematically examined: (1) A blood-contaminated finger pressed against a clean surface; (2) blood contaminates a latent print that had been placed on a clean surface; (3) A clean finger pressed against a blood contaminated surface. The questions of reliability and limits of all three models were discussed. The relevancy of the approach to "which came first", based solely on the color of ridges was questioned. The first mechanical model most simulated a real situation, when previously cleaned, a blood contaminated finger touched a clean Formica or glass surface with pressure of 100-500g. Concerning the second model, it was observed that in the case of a greasy latent print, placed on an inclined surface and contaminated with appropriate amount of blood, the color of ridges were normally darker than the color of its valleys. As for the third model, it was concluded that it works only in about 25% of cases. While investigating this model, two phenomena were observed: ridge color inversion and valley color inversion. In conclusion the color of ridges can not be the only and ultimate indicator to the question of "which came first", the fingermark or the blood stain. PMID- 29574350 TI - Pilot study of feature-based algorithm for breech face comparison. AB - A novel feature-based method, which is scale invariant feature transform (SIFT) and RANdom SAmple Consensus (RANSAC) integration algorithm, is introduced to promote the automated identification of the breech face impression, the most common mark left on the cartridge used for firearm evidence. SIFT algorithm is employed to extract the local extrema from examined impression as keypoints representing its invariant features, and to build the feature descriptor for each keypoint based on its local gradients in neighborhood. RANSAC is used to improve the matching performance among these keypoints and feature descriptors. With hypothesize-and-verify methods, RANSAC is able to construct the best model fitting initial matching pairs of keypoints and to guarantee the robust comparison result. Validation tests using 40 cartridge cases fired from pistols with 10 consecutively manufactured slides yielded a clear separation result, which strongly supports the effectiveness of the ensemble algorithm of SIFT and RANSAC. This application indicates the practical feasibility of feature-based algorithm and image processing technique in forensic science. PMID- 29574351 TI - Soil chemistry changes beneath decomposing cadavers over a one-year period. AB - Decomposing vertebrate cadavers release large, localized inputs of nutrients. These temporally limited resource patches affect nutrient cycling and soil organisms. The impact of decomposing cadavers on soil chemistry is relevant to soil biology, as a natural disturbance, and forensic science, to estimate the postmortem interval. However, cadaver impacts on soils are rarely studied, making it difficult to identify common patterns. We investigated the effects of decomposing pig cadavers (Sus scrofa domesticus) on soil chemistry (pH, ammonium, nitrate, nitrogen, phosphorous, potassium and carbon) over a one-year period in a spruce-dominant forest. Four treatments were applied, each with five replicates: two treatments including pig cadavers (placed on the ground and hung one metre above ground) and two controls (bare soil and bags filled with soil placed on the ground i.e. "fake pig" treatment). In the first two months (15-59 days after the start of the experiment), cadavers caused significant increases of ammonium, nitrogen, phosphorous and potassium (p<0.05) whereas nitrate significantly increased towards the end of the study (263-367 days; p<0.05). Soil pH increased significantly at first and then decreased significantly at the end of the experiment. After one year, some markers returned to basal levels (i.e. not significantly different from control plots), whereas others were still significantly different. Based on these response patterns and in comparison with previous studies, we define three categories of chemical markers that may have the potential to date the time since death: early peak markers (EPM), late peak markers (LPM) and late decrease markers (LDM). The marker categories will enhance our understanding of soil processes and can be highly useful when changes in soil chemistry are related to changes in the composition of soil organism communities. For actual casework further studies and more data are necessary to refine the marker categories along a more precise timeline and to develop a method that can be used in court. PMID- 29574352 TI - Visual characteristics for sequencing of overlapping bloodstain patterns. AB - The deposition sequence of overlapping bloodstain patterns can be valuable reconstructive information. A formal method for sequencing overlapping bloodstain patterns has yet to be published. We present a method for sequencing overlapping transfer and drip stains using visual characteristics. A survey was held amongst educated bloodstain pattern analysts to determine whether the newly acquired method will assist them in correctly sequencing these overlapping bloodstain patterns. Results showed a significant improvement of expert decisions: the percentage of overlapping stains correctly sequenced by participants increased from 57 to 79% using the visual characteristics defined in this study. These results suggest that a decision support system can be built, which helps investigators at the crime scene to sequence overlapping bloodstain patterns. PMID- 29574353 TI - Preliminary investigation of cognitive function in aged multiple sclerosis patients: Challenges in detecting comorbid Alzheimer's disease. AB - BACKGROUND: Cognitive impairment can be seen in patients of all ages with multiple sclerosis (MS). However, there is limited research on neurocognitive disorder in older adults with MS and how to detect Alzheimer's disease (AD) or its prodromal stage, amnestic mild cognitive impairment (aMCI). Thus, the MS clinician is challenged to discriminate between signs of MS-related cognitive decline versus a secondary neurodegenerative process. OBJECTIVE: Compare cognition in older MS patients to patients with AD and aMCI. METHODS: We evaluated cognitively impaired and unimpaired MS patients, AD patients, aMCI patients, and healthy controls (HCs), all elderly (n = 20 per group). AD and aMCI diagnoses were derived by consensus conference independent of the MS research project. Neuropsychological measures assessed domains commonly affected in AD, including verbal memory and expressive language. RESULTS: Cognitively impaired and unimpaired MS groups did not differ on any measures sensitive to AD. Unimpaired MS patients were comparable to HCs. Impaired MS patients showed decreased semantic fluency, similar to aMCI patients. Lastly, while both AD and aMCI groups had deficient memory retention, there was no evidence of a retention deficit in either MS group. CONCLUSION: Our findings suggest that the cognitive profiles of MS and AD are distinct. In contrast to AD, MS is not associated with impairment of memory consolidation. However, there may be overlap between cognitive deficits related to MS and aMCI. Thus, evidence of poor memory retention, in an older MS patient may merit comprehensive dementia evaluation. The study is preliminary and includes no AD biomarkers (e.g., amyloid imaging) to confirm or rule out AD pathology.

PMID- 29574355 TI - Early prediction of olanzapine-induced weight gain for schizophrenia patients. AB - The aim of this study was to determine whether weight changes at week 2 or other factors predicted weight gain at week 6 for schizophrenia patients receiving olanzapine. This study was the secondary analysis of a six-week trial for 94 patients receiving olanzapine (5 mg/d) plus trifluoperazine (5 mg/d), or olanzapine (10 mg/d) alone. Patients were included in analysis only if they had completed the 6-week trial (per protocol analysis). Weight gain was defined as a 7% or greater increase of the patient's baseline weight. The receiver operating characteristic curve was employed to determine the optimal cutoff points of statistically significant predictors. Eleven of the 67 patients completing the 6 week trial were classified as weight gainers. Weight change at week 2 was the statistically significant predictor for ultimate weight gain at week 6. A weight change of 1.0 kg at week 2 appeared to be the optimal cutoff point, with a sensitivity of 0.92, a specificity of 0.75, and an AUC of 0.85. Using weight change at week 2 to predict weight gain at week 6 is favorable in terms of both specificity and sensitivity. Weight change of 1.0 kg or more at 2 weeks is a reliable predictor. PMID- 29574356 TI - Use of Ecological Momentary Assessment (EMA) in Non-Suicidal Self-Injury (NSSI): A systematic review. AB - Conceptualization and assessment of non-suicidal self-injury (NSSI) has evolved substantially in recent years. In both cross-sectional and longitudinal studies, NSSI and its related variables have traditionally been assessed retrospectively, leading to less precise studies of the mechanisms involved in the maintenance, cessation, or aggravation of this behavior. Ecological momentary assessment (EMA) enables real-time collection of patient states, which can be very useful in the study of the mechanisms implied in this behavior. This systematic review aims to elucidate the current status of EMA use in NSSI investigation. An exhaustive search in PubMed and PsycINFO was conducted up to September 2017. All papers included were focused on the study of NSSI using EMA. Studies with methodological diversity were included, which were afterwards organized according to main topic of studies. There were no ineligibility criteria based on age or diagnosis. Twenty-three papers were studied, the majority of which are short-term studies focused on the study of affect dynamics and the emotion-regulation function of NSSI. Implications of these results and recommendations for future research are discussed. PMID- 29574358 TI - Hormonal changes and folliculogenesis in female offspring of rats exposed to cadmium during gestation and lactation. AB - It has been suggested that the toxic effects of cadmium (Cd) may disrupt ovarian and uterine functions in adults. However, Cd exposure during gestation and lactation and its effects on the reproductive development in female offspring is still not clear, and the mechanisms underlying exposure toxicology remain mostly unexplored. To investigate how Cd exposure of female rats (F0) during gestation and lactation affects the reproductive development of their female offspring, we studied the steroidogenesis, folliculogenesis, puberty onset, and litter size of the first (F1) and second (F2) filial generations following F0 female rats which had been exposed to CdCl2. The mechanisms related to the early onset of puberty induced by such exposure in female offspring were explored. Maternal exposure to Cd dramatically increased the biosynthesis of steroid hormones in F1 female offspring by the activation of cAMP/PKA pathway and up-regulated expression of steroidogenesis related proteins such as StAR, CYP11A1, 3beta-HSD and CYP19A1. The high levels of steroid hormones contributed to an early puberty onset, promoted the differentiation and maturation of follicles, and led to the proliferation of endometrium that resulted in a uterus weight gain. The increased number of antral follicles eventually caused a big litter size. Despite of being free from additional Cd exposure, the levels of CYP11A1 and CYP19A1 in the ovaries of F2 female rats were also high, which resulted in a high concentration of serum progesterone. These results suggested that hormonal changes induced by exposure to Cd in utero might have a lasting effect beyond the first generation. These findings may help to better understand the origin of female sexual dysfunction in the developmental stages in general. PMID- 29574357 TI - Repression of adenosine triphosphate-binding cassette transporter ABCG2 by estrogen increases intracellular glutathione in brain endothelial cells following ischemic reperfusion injury. AB - The adenosine triphosphate-binding cassette efflux transporter ABCG2, which is located in the blood-brain barrier limits the entry of endogenous compounds and xenobiotics into the brain, and its expression and activity are regulated by estrogen. This study was aimed to define the role of ABCG2 in estrogen-mediated neuroprotection against ischemic injury. ABCG2 protein levels before and after ischemic stroke were increased in the brain of female mice by ovariectomy, which were reversed by estrogen replacement. In brain endothelial cell line bEnd.3, estrogen reduced the basal ABCG2 protein level and efflux activity and protected cells from ischemic injury without inducing ABCG2 expression. When bEnd.3 cells were transfected with ABCG2 small interfering RNA, ischemia-induced cell death was reduced, and the intracellular concentration of glutathione, an antioxidant that is transported by ABCG2, was increased. In addition, after ischemic stroke in ovariectomized mice, estrogen prevented the reduction of intracellular glutathione level in brain microvessels. These data suggested that the suppression of ABCG2 by estrogen is involved in neuroprotection against ischemic injury by increasing intracellular glutathione, and that the modulation of ABCG2 activity offers a therapeutic target for brain diseases in estrogen-deficient aged women. PMID- 29574359 TI - Bioavailability and uptake of smelter emissions in freshwater zooplankton in northeastern Washington, USA lakes using Pb isotope analysis and trace metal concentrations. AB - The upper Columbia River and associated valley systems are highly contaminated with metal wastes from nearby smelting operations in Trail, British Columbia, Canada (Teck smelter), and to a lesser extent, Northport, Washington, USA (Le Roi smelter). Previous studies have investigated depositional patterns of airborne emissions from these smelters, and documented the Teck smelter as the primary metal contamination source. However, there is limited research directed at whether these contaminants are bioavailable to aquatic organisms. This study investigates whether smelter derived contaminants are bioavailable to freshwater zooplankton. Trace metal (Zn, Cd, As, Sb, Pb and Hg) concentrations and Pb isotope compositions of zooplankton and sediment were measured in lakes ranging from 17 to 144 km downwind of the Teck smelter. Pb isotopic compositions of historic ores used by both smelters are uniquely less radiogenic than local geologic formations, so when zooplankton assimilate substantial amounts of smelter derived metals their compositions deviate from local baseline compositions toward ore compositions. Sediment metal concentrations and Pb isotope compositions in sediment follow significant (p < 0.001) negative exponential and sigmoidal patterns, respectively, as distance from the Teck smelting operation increases. Zooplankton As, Cd, and Sb contents were related to distance from the Teck smelter (p < 0.05), and zooplankton Pb isotope compositions suggest As, Cd, Sb and Pb from historic and current smelter emissions are biologically available to zooplankton. Zooplankton from lakes within 86 km of the Teck facility display isotopic evidence that legacy ore pollution is biologically available for assimilation. However, without water column data our study is unable to determine if legacy contaminants are remobilized from lake sediments, or erosional pathways from the watershed.

AB - A column leaching study, coupled with acid deposition simulation, was conducted to investigate the leaching of potentially toxic metals (PTM) from zinc smelting slag materials (SSM) after being incubated in an acid Alfisol for 120 days at room temperature. Two SSMs (SSM-A: acidic, 10 yrs exposure with moderate high PTM concentrations versus SSM-B: alkaline, 2 yrs exposure with extremely high PTM concentrations), were used for the incubation at 0.5, 1, 2.5, 5 wt% amendment ratios in triplicate. Five leaching events were conducted at day 1, 3, 7, 14, and 28, and the leaching of PTMs mainly occurred in the first three leaching events, with the highest PTM concentrations in leachate measured from 5 wt% SSM amendments. After leaching, 2.5, 12, 5.5, 14, 11, and 9 wt% of M3 extractable Pb, Zn, Cd, Co, Cr, and Ni could be released from 5 wt% SSM-A amended soils, being respectively 25, 12, 4, 2, 2, and 2 times more than those from 5 wt% SSM-B amended soils. In the leachates, the concentrations of PTMs were mostly affected by leachant pH and were closely correlated to the concentrations of Fe, Al, Ca, Mg and P with Cd, Pb, and Zn showing the most environmental concern. Visual MINTEQ 3.1 modeling suggested metallic ions and sulfate forms as the common chemical species of PTMs in the leachates; whereas, organic bound species showed importance for Cd, Pb, Cu, and Ni, and CdCl+ was observed for Cd. Aluminum hydroxy, phosphate, and sulfate minerals prevailed as the saturated minerals, followed by chloropyromorphite (Pb5(PO4)3Cl) and plumbogummite (PbAl3(PO4)2(OH)5.H2O) in the leachates. This study suggested that incubation of SSMs in acidic soil for a long term can enhance the release of PTMs as the forms of metallic ions and sulfate when subjected to acid deposition leaching.

AB - We analyzed the conjoint effects of sewage inputs and hydrological alteration on the occurrence of teratological forms and on the assemblage composition of stream benthic diatoms. The study was performed in 11 Mediterranean streams which received treated or untreated urban sewage (Impact sites, I), whose composition and morphological anomalies were compared to upstream unaffected (Control, C) sites. The impact sites had high concentrations of ammonium, phosphorus, and pharmaceutical compounds (antibiotics, analgesics, and anti-inflammatories), particularly in those receiving untreated sewage. Impact sites had a higher proportion of teratological forms as well as a prevalence of diatom taxa tolerant to pollution. The differences in the diatom assemblage composition between the paired C and I sites were the largest in the impacted sites that received untreated sewage inputs as well as in the systems with lower dilution capacity. In these sites, the diatom assemblage was composed by a few pollution-tolerant species. Mediterranean river systems facing hydrological stress are highly sensitive to chemical contamination, leading to the homogenization of their diatom assemblages.

AB - Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Nitrogen-enriched rivers are significant sources of atmospheric N2O. This study conducted a one-year field campaign in seven N-enriched rivers draining urban, rural, and agricultural land to determine the link between the production, concentrations, and emissions of N2O and land use. Estimated N2O fluxes varied between 1.30 and 1164.38 MUg N2O-N m-2 h-1 with a mean value of 154.90 MUg N2O-N m-2 h-1, indicating that rivers were the net sources of atmospheric N2O. Concentrations of N2O ranged between 0.23 and 29.21 MUg N2O-N L-1 with an overall mean value of 3.81 MUg N2O-N L-1. Concentrations of ammonium and nitrate in urban and rural rivers were high in the cold season. The concentrations were also high in agricultural rivers in the wet season. N2O concentrations and emissions in rural and urban rivers followed a similar pattern to ammonium and a similar pattern to nitrate in agricultural rivers. A strong link between the concentrations and emissions of N2O and land use was observed. N2O concentrations in and emissions from the rivers draining the urban and rural areas were significantly higher than the rivers draining the agricultural areas (P < 0.01). Stepwise regression analysis indicated that dissolved N2O were primarily influenced by NH4+ in agricultural rivers and by NO3- in rural rivers; while dissolved N2O in urban rivers was primarily predicted by temperature and reflected the integrated impact of sewage input and river hydrology. Nitrate-N and NO3--O isotope data and linear regression of N2O and river water variables strongly indicated that dissolved N2O was mainly derived from nitrification in agricultural rivers and denitrification in rural and urban rivers.

AB - BACKGROUND: The static foot posture has been related to the development of lower limb injuries. RESEARCH QUESTION: This study aimed to investigate the dynamic stiffness of foot joints during gait in the sagittal plane to understand the role of the static foot posture in the development of injuries. METHODS: Seventy healthy adult male subjects with different static postures, assessed by the Foot Posture Index (FPI) (30 normal, 20 highly pronated and 20 highly supinated), were recruited. Kinematic and kinetic data were recorded using an optical motion capture system and a pressure platform, and dynamic stiffness at the different stages of the stance was calculated from the slopes of the linear regression on the flexion moment-angle curves. The effect of foot type on dynamic stiffness and on ranges of motion and moments was analysed using ANOVAs and post-hoc tests, and linear correlation between dynamic stiffness and FPI was also tested. RESULTS: Highly pronated feet showed a significantly smaller range of motion at the ankle and metatarsophalangeal joints and also a larger range of moments at the metatarsophalangeal joint than highly supinated feet. Dynamic stiffness during propulsion was significantly greater at all foot joints for highly pronated feet, with positive significant correlations with the squared FPI. Highly supinated feet showed greater dynamic stiffness than normal feet, although to a lesser extent. Highly pronated feet during normal gait experienced the greatest decrease in the dorsiflexor moments during propulsion, normal feet being the most balanced regarding work generated and absorbed. SIGNIFICANCE: Extreme static foot postures show greater dynamic stiffness during propulsion and greater absorbed work, which increases the risk of developing injuries. The data presented may be used when designing orthotics or prostheses, and also when planning surgery that modifies joint stiffness. PMID- 29574364 TI - Prognostic relevance of distant metastases versus locally advanced disease in soft tissue sarcomas: An EORTC-STBSG database study. AB - INTRODUCTION: In patients with advanced soft tissue sarcoma (STS) treated with chemotherapy, WHO performance status, histologic subtype and histologic grade are known prognostic factors. Although the difference between the subgroups: locally advanced disease only, metastatic disease only and both local and metastatic disease is easily made, its prognostic relevance is thus far unknown. The aim of this EORTC database study was to study the difference in prognosis between these subgroups in patients receiving first-line chemotherapy for advanced STS. METHODS: A retrospective database analysis was performed on 2473 patients receiving first-line chemotherapy for advanced STS from 12 EORTC sarcoma trials to establish the difference in prognosis for the three subgroups. End-points were overall survival, progression-free survival and overall response rate. Factors studied were age, sex, histologic subtype, histologic grade, WHO performance status, treatment and time since initial diagnosis. RESULTS: Overall survival differed significantly between patients with locally advanced disease only, with metastatic disease only and with both locally advanced and metastatic disease with a median overall survival of 15.4, 12.9 and 10.6 months, respectively. Similar differences were seen for progression-free survival (5.8, 4.3 and 3.2 months, respectively). CONCLUSION: This large retrospective database study shows that patients with advanced STSs treated with first-line chemotherapy with locally advanced disease, metastatic disease and both local and metastatic disease have different outcomes. This should be accounted for in future study design, interpretation and comparison of study results and daily practice. PMID- 29574365 TI - Health-related quality of life from the FALCON phase III randomised trial of fulvestrant 500 mg versus anastrozole for hormone receptor-positive advanced breast cancer. AB - BACKGROUND: The phase III randomised FALCON trial (NCT01602380) demonstrated improved progression-free survival with fulvestrant 500 mg versus anastrozole 1 mg in endocrine therapy-naive postmenopausal women with hormone receptor-positive (HR+) locally advanced or metastatic breast cancer (LA/MBC). Furthermore, overall health-related quality of life (HRQoL) was maintained and comparable for fulvestrant and anastrozole. Here, we present additional analyses of patient reported HRQoL outcomes from FALCON. METHODS: Women with endocrine therapy-naive HR+ LA/MBC were randomised 1:1 to fulvestrant (days 0, 14, 28, then every 28 d) or anastrozole (daily) until disease progression or discontinuation. HRQoL was assessed by FACT-B questionnaire (TOI and FACT-B total score) at randomisation and every 12 weeks during treatment. HRQoL data post-treatment (with or without progression) were also collected. RESULTS: In total, 462 patients were randomised (fulvestrant, n = 230; anastrozole, n = 232). Compliance to FACT-B overall ranged from 60.0 to 97.4%. Mean change from baseline in TOI and FACT-B total score remained broadly stable (approximately +/- 3 points to week 132) and was similar between arms during treatment. HRQoL was also maintained in FACT-B subscales. Approximately one-third of patients had improved TOI (>=+6 points) and FACT-B (>=+8 points) total scores from baseline up to week 120 and 132, respectively, of treatment with fulvestrant (ranges 26.4-45.0% and 22.4-35.8%, respectively) and anastrozole (ranges 18.6-32.9%, and 22.7-37.9%, respectively). CONCLUSIONS: Mean change from baseline in TOI and FACT-B total score was maintained for fulvestrant and anastrozole; similar proportions of patients in both arms had improved TOI and FACT-B total scores. CLINICALTRIALS. GOV IDENTIFIER: NCT01602380. PMID- 29574366 TI - Long-term manure application increased greenhouse gas emissions but had no effect on ammonia volatilization in a Northern China upland field. AB - The impacts of manure application on soil ammonia (NH3) volatilization and greenhouse gas (GHG) emissions are of interest for both agronomic and environmental reasons. However, how the swine manure addition affects greenhouse gas and N emissions in North China Plain wheat fields is still unknown. A long term fertilization experiment was carried out on a maize-wheat rotation system in Northern China (Zea mays L-Triticum aestivum L.) from 1990 to 2017. The experiment included four treatments: (1) No fertilizer (CK), (2) single application of chemical fertilizers (NPK), (3) NPK plus 22.5t/ha swine manure (NPKM), (4) NPK plus 33.7t/ha swine manure (NPKM+). A short-term fertilization experiment was conducted from 2016 to 2017 using the same treatments in a field that had been abandoned for decades. The emissions of NH3 and GHGs were measured during the wheat season from 2016 to 2017. Results showed that after long-term fertilization the wheat yields for NPKM treatment were 7105kg/ha, which were higher than NPK (3880kg/ha) and NPKM+ treatments (5518kg/ha). The wheat yields were similar after short-term fertilization (6098-6887kg/ha). The NH3-N emission factors (EFamm) for NPKM and NPKM+ treatments (1.1 and 1.1-1.4%, respectively) were lower than NPK treatment (2.2%) in both the long and short-term fertilization treatments. In the long- and short-term experiments the nitrous oxide (N2O) emission factors (EFnit) for NPKM+ treatment were 4.2% and 3.7%, respectively, which were higher than for the NPK treatment (3.5% and 2.5%, respectively) and the NPKM treatment (3.6% and 2.2%, respectively). In addition, under long and short-term fertilization, the greenhouse gas intensities for the NPKM+ treatment were 33.7 and 27.0kg CO2-eq/kg yield, respectively, which were higher than for the NPKM treatment (22.8 and 21.1kg CO2-eq/kg yield, respectively). These results imply that excessive swine manure application does not increase yield but increases GHG emissions. PMID- 29574367 TI - Effects of topography and soil properties on soil selenium distribution and bioavailability (phosphate extraction): A case study in Yongjia County, China. AB - Selenium (Se) is an essential trace element for humans. In order to investigate how soil Se is influenced by topography and soil properties, we selected Yongjia County, an area with mountainous topography, as a study area. This study used cultivated soil data to comprehensively analyze the effects of topography and soil properties on Se mobility and bioavailability and to identify the key factors influencing Se distribution in the environment. Factors considered in this study were elevation, slope, topographic wetness index, the coefficient of weathering and eluviation, pH, organic matter, and Fe2O3. The concentration of total soil Se (0.382+/-0.123mgkg-1) was far higher than the background value of soil in China, and 98% of the soil samples were classified as having moderate Se levels (>0.175mgkg-1), indicating Yongjia County is a Se-rich region in China. Phosphate extracted Se accounted for an average of 9% of the total Se and was significantly associated with soil total Se, Fe2O3, pH, and the coefficient of weathering and eluviation. Fe2O3 primarily controlled Se adsorption, fixation, and availability in soil. Under the geo-environmental conditions in the study area, the total Se in the soil increased first and then decreased with increases in elevation, slope, and the topographic wetness index, and the phosphate extracted Se showed similar patterns except for the elevation. The findings showed that topographical attributes and soil physicochemical properties synthetically influenced the distribution and bioavailability of Se in soil.

AB - This study aimed to shed further light on the capacity of the seagrass Halophila stipulacea to accumulate and biomonitor the elements As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn, present in water and sediments. Results showed that the organs of H. stipulacea accumulate different levels of trace elements, whose concentrations decrease mainly in the order of roots>rhizomes>leaves. The seagrass H. stipulacea showed levels of trace elements similar to those found in other Mediterranean seagrasses, e.g. Posidonia oceanica and Cymodocea nodosa. This study showed that H. stipulacea could act as a promising bioindicator of several elements, present in sediments, including As, Cd, Cu, Mn, Ni and Zn. PMID- 29574368 TI - Estimation of the consumption of illicit drugs during special events in two communities in Western Kentucky, USA using sewage epidemiology. AB - Sewage epidemiology is a cost-effective, comprehensive, and non-invasive technique capable of determining semi-real-time community usage of drugs utilizing the concentration of drug residues in wastewater, wastewater inflow, and the population size served by a wastewater treatment plant. In this study, semi-real-time consumption rates of ten illicit drugs were determined using sewage epidemiology during special events including Independence Day, the 2017 solar eclipse, and the first week of an academic semester in the Midwestern United States. The average per-capita consumption rate of amphetamine, methamphetamine, cocaine, and THC were significantly different between two similar-sized communities during Independence Day observation week (p<0.046) and a typical week (p<0.001). Compared to a typical day, the consumption rate of amphetamine, methamphetamine, cocaine, morphine, and methadone was significantly higher on Independence Day (p<0.021) and during solar eclipse observation (p=0.020). The estimated percentage of the population that consumed cocaine in a community is similar to the conventionally estimated consumption of cocaine; however, the combined estimated population that consumed amphetamine and methamphetamine based on sewage epidemiology was ~2 to 4 fold higher than the conventional estimates. This study is the first to compare community use of drugs during special events in the USA using sewage epidemiology. PMID- 29574370 TI - Experimental study on the heat transfer characteristics of waste printed circuit boards pyrolysis. AB - In order to study the appropriate and advanced technology for recycling waste printed circuit boards (PCBs), a fixed bed pyrolysis device with stirring function has been designed and developed. The effect of rotating speed on the temperature distribution and mass change in the pyrolysis process of FR-4 PCB has been analyzed. The heat transfer and pyrolysis characteristics of different granular layers with and without stirring have been investigated. The results indicate that the stirring can change the main way of heat transfer from conduction to convection in the PCB layers. As the increase of rotating speed, the temperature rising rate of material at the bottom of the pyrolysis furnace gradually decreases, while the heating rate is increasing at the upper layer, and the temperature difference between the upper and bottom layers is gradually reduced. When the rotating speed varies from 0r/min to 18r/min, the weight loss of the material increases from 3.97% to 6.76%, and the overall pyrolysis degree is improved. During the pyrolysis process, the material layer can be divided into three zones along the vertical direction, namely complete pyrolysis zone, partial pyrolysis zone and non-pyrolysis zone. As the rotating speed is 0r/min, the thickness of each zones is 6cm, 6cm and 3cm, respectively. However, when the rotating speed is increased to 18r/min, the non-pyrolysis zone disappears, and the thickness of complete pyrolysis zone and partial pyrolysis zone increase to 9cm and 6cm, respectively. PMID- 29574371 TI - Identifying efficient agricultural irrigation strategies in Crete. AB - Water scarcity and droughts are a major concern in most Mediterranean countries. Agriculture is a major user of water in the region and releases significant amounts of surface and ground waters, endangering the sustainable use of the available resources. Best Management Practices (BMPs) can mitigate the agriculture impacts on quantity of surface waters in agricultural catchments. However, identification of efficient BMPs strategies is a complex task, because BMPs costs and effectiveness can vary significantly within a basin. In this study, sustainable agricultural practices were studied based on optimal allocation of irrigation water use for dominant irrigated crops in the island of Crete, Greece. A decision support tool that integrates the Soil and Water Assessment Tool (SWAT) watershed model, an economic model, and multi-objective optimization routines, was used to identify and locate optimal irrigation strategies by considering crop water requirements, impact of irrigation changes on crop productivity, management strategies costs, and crop market prices. Three spatial scales (crop type, fields, and administrative regions) were considered to point out different approaches of efficient management. According to the analysis, depending on the spatial scale and complexity of spatial optimization, water irrigation volumes could be reduced by 32%-70% while preserving current agricultural benefit. Specific management strategies also looked at ways to relocate water between administrative regions (4 prefectures in the case of Crete) to optimize crop benefit while reducing global water use. It was estimated that an optimal reallocation of water could reduce irrigation water volumes by 52% (148 Mm3/y) at the cost of a 7% (48 M?) loss of agricultural income, but maintaining the current agricultural benefit (626.9 M?). The study showed how the identification of optimal, cost-effective irrigation management strategies can potentially address the water scarcity issue that is becoming crucial for the viability of agriculture in the Mediterranean region. PMID- 29574372 TI - Post-wildfire management effects on short-term evolution of soil properties (Catalonia, Spain, SW-Europe). AB - Post-fire management practices after wildfires have an important impact on soil properties. Nevertheless, little research has been carried out. The aim of this study is to examine the impact of different post-wildfire forest management practices in a 10-month period immediately after a severe wildfire on soil properties. Two months after a wildfire, three experimental areas were designed, each one with different post-fire management: Cut and Remove (CR) where burned trunks were cut after fire and removed manually from the area; No Treatment (NT) where no intervention was carried out; and, Cut and Leave (CL) where burned trunks were cut and left randomly on topsoil. In each treatment, we collected nine samples (0-5cm deep). In total, we sampled 27 samples in each sampling date, two and ten months after the wildfire. The properties analyzed were aggregate stability (AS), total nitrogen (TN), soil organic matter (SOM), inorganic carbon (IC), C/N ratio, pH, electrical conductivity (EC), extractable calcium (Ca), magnesium (Mg), sodium (Na) and potassium (K). Soil C/N ratio was significantly higher in CR and CL treatments 10months after fire comparing to 2months after. On the other hand, pH, extractable Ca, Mg and K were significantly higher in all the treatments 2months after fire than 10months after. Aggregate stability, TN and SOM were significantly higher in CR comparing to CL, 10months after the fire. IC was significantly higher in CL than in NT treatment, also, 10months after the fire. Electrical conductivity was significantly higher in CR and CL treatments 2months after fire comparing to 10months after. According to the results, CR and CL post-fire management did not differ importantly from the NT scenario, showing that manual wood management does not have detrimental impacts on soil properties compared to mechanical operations. PMID- 29574373 TI - Assessment of lead exposure among automobile technicians in Khyber Pakhtunkhwa, Pakistan. AB - Exposure to Pb among automobile technicians in selected towns of Khyber Pakhtunkhwa Province, Pakistan, was studied using a questionnaire, biological sampling (blood, hair, nails), and analysis of Pb biomonitoring data across various subgroups of occupation, age, and years of exposure. The study population included exposed automobile technicians (n=50) and a control group (n=50). The automobile technicians were further stratified into 4 groups: mechanics, auto body technicians, electricians, and painters. Mean Pb levels in biological samples of the automobile technicians were significantly higher than in the control group (P<0.01). The Pb concentrations (mean+/-standard deviation) in whole blood, hair, and nails of automobile technicians were 65.3+/-41.9MUgdL-1, 23.6+/-11.2mgkg-1 and 29.7+/-14.5mgkg-1, respectively, whereas concentrations in the control group were 21.7+/-17.6MUgdL-1, 4.8+/-3.4mgkg-1 and 7.2+/-3.9mgkg-1. Fifty two percent of the automobile technicians had blood levels >50MUgdL-1, but only 14% of the control group exceeded this level. Considering that Pb blood levels of 50MUgdL-1 exceed maximum concentrations recommended by leading public health organizations, appropriate measures should be taken to protect the welfare of the exposed automobile technicians and their families. PMID- 29574374 TI - Changes in heavy metal bioavailability and speciation from a Pb-Zn mining soil amended with biochars from co-pyrolysis of rice straw and swine manure. AB - Biochar has been utilized as a good amendment to immobilize heavy metals in contaminated soils. However, the effectiveness of biochar in metal immobilization depends on biochar properties and metal species. In this study, the biochars produced from co-pyrolysis of rice straw with swine manure at 400 degrees C were investigated to evaluate their effects on bioavailability and chemical speciation of four heavy metals (Cd, Cu, Pb and Zn) in a Pb-Zn contaminated soil through incubation experiment. Results showed that co-pyrolysis process significantly change the yield, ash content, pH, and electrical conductivity (EC) of the blended biochars compared with the single straw/manure biochar. The addition of these biochars significantly increased the soil pH, EC, and dissolved organic carbon (DOC) concentrations. The addition of biochars at a rate of 3% significantly reduced the CaCl2-extractable metal concentrations in the order of Pb>Cu>Zn>Cd. The exchangeable heavy metals decreased in all the biochar-amended soils whereas the carbonate-bound metal speciation increased. The increase in soil pH and the decrease in the CaCl2 extractable metals indicated that these amendments can directly transform the highly availability metal speciation to the stable speciation in soils. In conclusion, biochar derived from co-pyrolysis of rice straw with swine manure at a mass ratio of 3:1 could most effectively immobilize the heavy metals in the soil. PMID- 29574375 TI - Characterization and health risk assessment of airborne pollutants in commercial restaurants in northwestern China: Under a low ventilation condition in wintertime. AB - Impacts on indoor air quality of dining areas from cooking activities were investigated in eight categories of commercial restaurants including Szechwan Hotpot, Hunan, Shaanxi Noodle, Chinese Barbecue, Chinese Vegetarian, Korean Barbecue, Italian, and Indian, in Northwestern China during December 2011 to January 2012. Chemical characterization and health risk assessment for airborne carbonyls, and particulate-bound polycyclic aromatic hydrocarbons (PAHs) and heavy metals were conducted under low ventilation conditions in wintertime. The highest total quantified carbonyls (Sigmacarbonyls) concentration of 313.6MUgm-3 was found in the Chinese Barbecue, followed by the Szechwan Hotpot (222.6MUgm-3) and Indian (221.9MUgm-3) restaurants. However, the highest Sigmacarbonyls per capita was found at the Indian restaurant (4500MUgcapita-1), suggesting that cooking methods such as stir-fly and bake for spices ingredients released more carbonyls from thermal cooking processes. Formaldehyde, acetaldehyde, and acetone were the three most abundant species, totally accounting for >60% of mass concentrations of the Sigmacarbonyls. Phenanthrene, chrysene, and benzo[a]anthracene were the three most abundant PAHs. Low molecular weight fraction (SigmaPAHs<=178) had the highest contributions accounting for 40.6% 65.7%, much greater than their heaver counterparts. Diagnostic PAHs ratios suggest that cooking fuel and environmental tobacco smoke (ETS) contribute to the indoor PAHs profiles. Lead was the most abundant heavy metal in all sampled restaurants. High quantity of nickel was also found in samples due to the emissions from stainless-steel made kitchen utensils and cookware and ETS. Cancer risk assessments on the toxic substances demonstrate that the working environment of dining areas were hazard to health. Formation of reactive organic species (ROS) from the cooking activities was evidenced by measurement of hydroxyl radical (OH) formed from simulating particulate matter (PM) react with surrogate lung fluid. The highest OH concentration of 294.4ngm-3 was detected in Chinese Barbecue. In addition, the elevation of the concentrations of PM and OH after non dining periods implies that the significance of formation of oxidizing-active species indoor at poor ventilation environments.

AB - An online-coupled regional Weather Research and Forecasting model with chemistry (WRF-Chem) is utilized incorporating 0.1 degrees *0.1 degrees spatial resolution HTAP (Hemispheric Transport of Air Pollution) anthropogenic emissions to investigate the spatial and temporal distribution of a Saharan dust outbreak, which contributed to high levels (>50MUg/m3) of daily PM10 concentrations over Turkey in April 2008. Aerosol optical depth and cloud optical thickness retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on board of Aqua satellite are used to better analyze the synoptic conditions that generated the dust outbreak in April 2008. A "Sharav" low pressure system, which transports the dust from Saharan source region over Turkey along the cold front, tends to move faster in WRF-Chem simulations than observed. This causes the predicted dust event to arrive earlier than observed leading to an overestimation of surface PM10 concentrations in WRF-Chem simulation at the beginning of the event. PMID- 29574377 TI - Atmospheric nitrate export in streams along a montane to urban gradient. AB - Nitrogen (N) emissions associated with urbanization exacerbate the atmospheric N influx to remote ecosystems - like mountains -, leading to well-documented detrimental effects on ecosystems (e.g., soil acidification, pollution of freshwaters). Here, the importance and fate of N deposition in a watershed was evaluated along a montane to urban gradient, using a multi-isotopic tracers approach (Delta17O, delta15N, delta18O of nitrate, delta2H and delta18O of water). In this setting, the montane streams had higher proportions of atmospheric nitrate compared to urban streams, and exported more atmospheric nitrate on a yearly basis (0.35 vs 0.10 kg-Nha-1yr-1). In urban areas, nitrate exports were driven by groundwater, whereas in the catchment head nitrate exports were dominated by surface runoff. The main sources of nitrate to the montane streams were microbial nitrification and atmospheric deposition, whereas microbial nitrification and sewage leakage contributed most to urban streams. Based on the measurement of delta15N and delta18O-NO3-, biological processes such as denitrification or N assimilation were not predominant in any streams in this study. The observed low delta15N and delta18O range of terrestrial nitrate (i.e., nitrate not coming from atmospheric deposition) in surface water compared to literature suggests that atmospheric deposition may be underestimated as a direct source of N. PMID- 29574378 TI - Exploring synergistic benefits of Water-Food-Energy Nexus through multi-objective reservoir optimization schemes. AB - This study proposed a holistic three-fold scheme that synergistically optimizes the benefits of the Water-Food-Energy (WFE) Nexus by integrating the short/long term joint operation of a multi-objective reservoir with irrigation ponds in response to urbanization. The three-fold scheme was implemented step by step: (1) optimizing short-term (daily scale) reservoir operation for maximizing hydropower output and final reservoir storage during typhoon seasons; (2) simulating long term (ten-day scale) water shortage rates in consideration of the availability of irrigation ponds for both agricultural and public sectors during non-typhoon seasons; and (3) promoting the synergistic benefits of the WFE Nexus in a year round perspective by integrating the short-term optimization and long-term simulation of reservoir operations. The pivotal Shihmen Reservoir and 745 irrigation ponds located in Taoyuan City of Taiwan together with the surrounding urban areas formed the study case. The results indicated that the optimal short term reservoir operation obtained from the non-dominated sorting genetic algorithm II (NSGA-II) could largely increase hydropower output but just slightly affected water supply. The simulation results of the reservoir coupled with irrigation ponds indicated that such joint operation could significantly reduce agricultural and public water shortage rates by 22.2% and 23.7% in average, respectively, as compared to those of reservoir operation excluding irrigation ponds. The results of year-round short/long-term joint operation showed that water shortage rates could be reduced by 10% at most, the food production rate could be increased by up to 47%, and the hydropower benefit could increase up to 9.33 million USD per year, respectively, in a wet year. Consequently, the proposed methodology could be a viable approach to promoting the synergistic benefits of the WFE Nexus, and the results provided unique insights for stakeholders and policymakers to pursue sustainable urban development plans. PMID- 29574379 TI - Use of an improved high-throughput absolute abundance quantification method to characterize soil bacterial community and dynamics. AB - High-throughput sequencing has dramatically expanded our understanding of bacterial communities based on the information of the species types and their relative abundances. Recently, researchers have also become aware of a deficiency in not considering the absolute abundance in this technique. Combining two or more different methods has typically been used to achieve absolute quantification of microbial communities. However, making a combination of different methods not only is time-consuming but also involves potential uncertainty due to variations in the experimental conditions. To simplify the experimental procedure and improve the high-throughput absolute abundance quantification (HAAQ) of a soil bacterial community, we propose an HAAQ method that uses an internal standard strain (ISS) HAAQ-GFP to simultaneously obtain both the relative and absolute abundances in the soil bacterial community. The results showed that a soil bacterial community and its dynamics can be better characterized by the HAAQ method when the optimal concentrations of ISS HAAQ-GFP (105 to 107cellsg-1) were used, and a 16S rRNA gene copy number adjustment was applied. Based on the HAAQ method, we first found that soil bacterial absolute abundances at the genus level fitted well to the partial log-normal distribution function, and most genera concentrations were in the range of 103.5 to 106.5cellsg-1 in the test soils. Our case studies also indicated that more comprehensive descriptions of soil bacterial communities and their dynamics can be achieved by both the relative and absolute abundances than by the relative abundance alone. The improved HAAQ method can be potentially applied to other microbial ecological studies and to stimulating the development of quantitative bacterial ecology studies.

AB - A simple, highly sensitive ultra-performance liquid chromatography- electrospray ionization-mass spectrometry (LC-ESI-MS) method has been developed to quantify of withanolide B and obakunone (IS) in guinea pig plasma and tissues, and to compare the pharmacokinetics and tissue distribution of withanolide B in normal and psoriasis guinea pigs. After mixing with IS, plasma and tissues were pretreated by protein precipitation with methanol. Chromatographic separation was performed on a C18 column using aqueous (0.1% formic acid) and acetonitrile (0.1% formic acid) solutions at 0.4 mL/min as the mobile phase. The gradient program was selected (0-4.0 min, 2-98% B; 4.0-4.5 min, 98-2% B; and 4.5-5 min, 2% B). Detection was performed on a 4000 QTRAP UPLC-ESI-MS/MS system from AB Sciex in the multiple reaction monitoring (MRM) mode. Withanolide B and obakunone (IS) were monitored under positive ionization conditions. The optimized mass transition ion-pairs (m/z) for quantitation were 455.1/109.4 for withanolide B and 455.1/161.1 for obakunone.

AB - A patient with a total laryngectomy and tracheoesophageal voice prosthesis presented with tracheobronchial aspiration of a Phillips-head screw that was swallowed inadvertently and aspirated around a loose-fitting prosthesis. A modified esophagram showed a screw in the right lung and free leakage of barium from the cervical esophagus around the prosthesis into the tracheobronchial tree. Chest radiographs and CT confirmed a screw in a right lower lobe bronchus with postobstructive pneumonia. When this complication occurs, it is important to extract the foreign body and, if necessary, to adjust or remove the prosthesis to prevent future aspiration pneumonias or foreign body aspiration. PMID- 29574382 TI - Design for an aberration corrected scanning electron microscope using miniature electron mirrors. AB - Resolution of scanning electron microscopes (SEMs) is determined by aberrations of the objective lens. It is well known that both spherical and chromatic aberrations can be compensated by placing a 90-degree bending magnet and an electron mirror in the beam path before the objective lens. Nevertheless, this approach has not led to wide use of these aberration correctors, partly because aberrations of the bending magnet can be a serious problem. A mirror corrector with two mirrors placed perpendicularly to the optic axis of an SEM and facing each other is proposed. As a result, only small-angle magnetic deflection is necessary to guide the electron beam around the top mirror to the bottom mirror and around the bottom mirror to the objective lens. The deflection angle, in the order of 50 mrad, is sufficiently small to avoid deflection aberrations. In addition, lateral dispersion at the sample plane can be avoided by making the deflection fields symmetric. Such a corrector system is only possible if the incoming beam can pass the top mirror at a distance in the order of millimeters, without being disturbed by the electric fields of electrodes of the mirror. It is proposed that condition can be satisfied with micro-scale electron optical elements fabricated by using MEMS technology. In the proposed corrector system, the micro-mirrors have to provide the exact negative spherical and chromatic aberrations for correcting the aberration of the objective lens. This exact tuning is accomplished by variable magnification between the micro-mirrors and the objective lens using an additional transfer lens. Extensive optical calculations are reported. Aberrations of the micro-mirrors were analyzed by numerical calculation. Dispersion and aberrations of the deflectors were calculated by using an analytical field model. Combination aberrations caused by the off-axis position of dispersive rays in the mirrors and objective lens were also analyzed. It is concluded that the proposed corrector system will be a promising candidate for simple and low-cost aberration correction in low-voltage SEMs. PMID- 29574383 TI - Interplay between COMT Val158Met, childhood adversities and sex in predicting panic pathology: Findings from a general population sample. AB - BACKGROUND: The single nucleotide polymorphism rs4680 of the catechol-O methyltransferase (COMT) gene has been implicated to be involved in the etiopathogenesis of panic. However, it remains unresolved whether rs4680 modifies the risk-association between early life stress and subsequent development of panic pathology. METHODS: The genotype of rs4680 was determined for n = 2242 adults with European ancestry from the Study of Health in Pomerania (SHIP, a regional longitudinal cohort study from northeastern Germany). Lifetime fearful spells, panic attacks and panic disorder were assessed according to DSM-IV in 2007-2010 (when participants were aged 29-89) using the Munich Composite International Diagnostic Interview (DIA-X/M-CIDI). Childhood adversities were assessed with the Childhood Trauma Questionnaire (CTQ). RESULTS: Logistic regressions with interaction terms (adjusted for sex and age) revealed that rs4680 interacted with total childhood adversity, emotional abuse and physical abuse in predicting panic disorder: Respective childhood adversities predicted panic disorder in carriers of the Val/Met or Met/Met genotype, but not Val/Val genotype. Moreover, a 3-way interaction was found between rs4680, emotional abuse and sex in predicting panic attacks: Emotional abuse predicted panic attacks among male carriers of the Val/Val genotype and female carriers of the Val/Met or Met/Met genotype, but not among male carriers of the Val/Met or Met/Met genotype or female carriers of the Val/Val genotype. LIMITATIONS: Genotype data were derived by imputation. Childhood adversities and panic were assessed retrospectively. CONCLUSIONS: Especially (female) carriers of the Val/Met or Met/Met genotype of rs4680 might profit from targeted early interventions to prevent the onset of panic after childhood adversities. PMID- 29574384 TI - Combined effects of temperature and salinity on the demographic response of Proales similis (Beauchamp, 1907) and Brachionus plicatilis (Muller, 1786) (Rotifera) to mercury. AB - The demographic response of the brackish-water rotifers Proales similis and Brachionus plicatilis to mercury (0.5, 2, 8 and 32 MUg L-1 of HgCl2) at different salinity levels (10 and 200/00) and two temperature (25 degrees C and 32 degrees C) regimes were evaluated. Median lethal concentration (LC50) for P. similis and B. plicatilis was 10 and 16 MUg L-1, respectively, showing that Proales similis was more sensitive to mercury than B. plicatilis. The rate of population increase (r) for both species was greater at 100/00 salinity and 32 degrees C (ranged from 0.6 to 0.95 d-1). The r-value decreased as the concentration of mercury in the medium increased. Regardless of the temperature, at lower salinity and higher mercury concentration (32 MUg L-1), P. similis died within six days. The survivorship of P. similis and B. plicatilis was higher at 25 degrees C than at 32 degrees C (ranged from 5 to 8 and 7-13 d, respectively). Fecundity was higher at 32 degrees C than at 25 degrees C for both rotifers species. There was a significant effect of the interaction among salinity, temperature, and mercury in both species on the reproductive variables such as net and gross reproductive rates, generation time and the rate of population increase. Considering the sensitivity of P. similis, we suggest that this species be included in the list of marine bioassay organisms. PMID- 29574385 TI - Effect of reducing agent on catalytic hydrodechlorination of aqueous-phase OCDD/F. AB - Removal/destruction of aqueous-phase octachlorodibenzo-p-dioxin (OCDD) and octachlorodibenzofuran (OCDF) via hydrodechlorination process (HDC) is experimentally evaluated over palladium/activated carbon (Pd/AC) catalyst. Pd catalyst is mainly used as active component for effectiveness in removing dioxin from wastewater. Studies on the removal of PCDD/Fs accomplished with HDC reaction in aqueous phase are limited and the influencing factors have not been clarified. In this study, high-concentration OCDD/F are selected as targets, and the effects of solvent and operating temperature on dechlorination efficiency are investigated via experimental tests. The results indicate that the highest hydrodechlorination efficiency is achieved with isopropanol as solvent. The OCDD/F removal efficiency achieved with the solution of 80% isopropanol is higher than that of 50% isopropanol, whereas the destruction efficiency of OCDD/F reveals the opposite trend. Generally, the removal and destruction efficiencies of PCDFs are higher than those of PCDDs. In addition, the activation energies of OCDD and OCDF are calculated with the Arrhenius equation as 24.8 and 23.1 kJ/mol, respectively. Stability tests are conducted with three cycles. Overall, the results indicate that a high performance (>=99%) can be achieved by combining hydrodechlorination with Pd/AC at a temperature range of 303-353 K, demonstrating that Pd/AC has good potential for removing PCDD/Fs from wastewater. PMID- 29574386 TI - Gender differences in mercury-induced hepatotoxicity: Potential mechanisms. AB - The accumulation of mercury in the liver causes hepatotoxicity. The organic anion transporter 3 (Oat3) and the multidrug-resistance associated protein 2 (Mrp2) are involved in the hepatic excretion of toxins and drugs and in the hepatic handling of mercury. The aim of this work was to study if there are gender-related differences in mercuric chloride (HgCl2)-induced hepatotoxicity in rats. Total mercury levels and protein expressions of Oat3 and Mrp2 in liver samples were also assessed to clarify the mechanisms underlying mercury-induced liver damage in male and female rats. Control and HgCl2-treated male and female Wistar rats were used. Hepatotoxicity was evaluated by plasma activity of transaminases and alkaline phosphatase, as well as by histopathological analysis. Oat3 and Mrp2 expression was assessed by immunoblotting. Female rats displayed a higher HgCl2 induced hepatotoxicity than male rats as demonstrated by the higher alterations in the plasma markers of liver damage and in the histopathology. The sex-related differences observed in the hepatic damage can be explained by the higher accumulation of mercury in liver from female rats. In this connection, after mercury treatment the expression of Mrp2 decreased in both sexes and the expression of Oat3 decreased only in males. The decreased in Oat3 abundance in the hepatocytes membranes in mercury-treated males would limit the uptake of mercuric ions into the liver protecting them from mercury hepatotoxicity. PMID- 29574387 TI - Towards "Precision Mining" of wastewater: Selective recovery of Cu from acid mine drainage onto diatomite supported nanoscale zerovalent iron particles. AB - This paper introduces the concept of 'Precision Mining' of metals which can be defined as a process for the selective in situ uptake of a metal from a material or media, with subsequent retrieval and recovery of the target metal. In order to demonstrate this concept nanoscale zerovalent iron (nZVI) was loaded onto diatomaceous earth (DE) and tested for the selective uptake of Cu from acid mine drainage (AMD) and subsequent release. Batch experiments were conducted using the AMD and nZVI-DE at 4.0-16.0 g/L. Results demonstrate nZVI-DE as highly selective for Cu removal with >99% uptake recorded after 0.25 h when using nZVI-DE concentrations >=12.0 g/L, despite appreciable concentrations of numerous other metals in the AMD, namely: Co, Ni, Mn and Zn. Cu uptake was maintained in excess of 4 and 24 h when using nZVI-DE concentrations of 12.0 and 16.0 g/L respectively. Near-total Cu release from the nZVI-DE was then recorded and attributed to the depletion of the nZVI component and the subsequent Eh, DO and pH recovery. This novel Cu uptake and release mechanism, once appropriately engineered, holds great promise as a novel 'Precision Mining' process for the rapid and selective Cu recovery from acidic wastewater, process effluents and leach liquors. PMID- 29574388 TI - Formation of DBPs and halogen-specific TOX in the presence of iopamidol and chlorinated oxidants. AB - Iopamidol is a known direct precursor to iodinated and chlorinated DBP formation; however, the influence of iopamidol on both iodo/chloro-DBP formation has yet to be fully investigated. This study investigated the effect of iopamidol on the formation and speciation of halogen-specific total organic halogen (TOX), as well as iodo/chloro-DBPs, in the presence of 3 source waters (SWs) from Northeast Ohio and chlorinated oxidants. Chlorination and chloramination of SWs were carried out at pH 6.5-9.0 and, different iopamidol and dissolved organic carbon (DOC) concentrations. Total organic iodine (TOI) loss was approximately equal (22-35%) regardless of SW. Total organic chlorine (TOCl) increased in all SWs and was substantially higher in the higher SUVA254 SWs. Iopamidol was a direct precursor to chloroform (CHCl3), trichloroacetic acid (TCAA), and dichloroiodomethane (CHCl2I) formation. While CHCl3 and TCAA exhibited different formation trends with varying iopamidol concentrations, CHCl2I increased with increasing iopamidol and DOC concentrations. Low concentrations of iodo-acids were detected without discernible trends. Total trihalomethanes (THMs), total haloacetic acids (HAAs), TOCl, and unknown TOCl (UTOCl) were correlated with fluorescence regional volumes and SUVA254. The yields of all these species showed a strong positive correlation with fulvic, humic, and combined humic and fulvic regions, as well as SUVA254. Iopamidol was then compared to the 3 SWs with respect to DBP yield. Although the SUVA254 of iopamidol was relatively high, it did not produce high yields of THMs and HAAs compared to the 3 SWs. However, chlorination of iopamidol did result in high yields of TOCl and UTOCl. PMID- 29574389 TI - Investigation of mercury adsorption and cyclic mercury retention over MnOx/gamma Al2O3 sorbent. AB - In this study mercury sorbent based on manganese oxides impregnated gamma-alumina was synthesized. Mercury retention characteristics were investigated by mercury speciation and thermal desorption experiments. No gaseous mercuric oxide was observed in mercury speciation experiments with a mercury mass balance ratio of 89.11%. Maximum mercury desorption peak at 480 degrees C indicated that mercury was adsorbed in the form of mercuric oxide. Three cycles of mercury retention were tested with different thermal treatment in-between to evaluate the cyclic performance. Changes in surface phase and manganese chemistry before and after thermal treatment were characterized by XRD and XPS. Deterioration in mercury retention capacity was observed after thermal desorption at 500 degrees C, which was interpreted with reduced initial adsorption rate calculated by Pseudo-second order kinetic model. XPS studies suggested that atomic ratios of Mn4+/(Mn4++Mn3+) decreased from 73.2% to 32.3% and 33.9% after thermal desorption in N2 and air, respectively. The reduction of MnO2 to Mn2O3 was irreversible thus the mercury retention capacity could not be restored by thermal desorption at high temperatures. Spent sorbents that were reactivated at 200 degrees C in air without thermal desorption at 500 degrees C possessed considerable cycling performance for mercury retention due to the preserved Mn4+.

AB - Food products such as bread, biscuits, tea, coffee, oils, chocolates, grapes, pepper and fishes belonging to different categories represent a significant part of everyday diet in India and other countries having variable cooking techniques. In this study, we evaluated cancer risks of long term exposure to polycyclic aromatic hydrocarbons (PAHs) through consumption of these products for eight societal groups in India. Total concentrations of PAHs in these products from India ranged from 0.18 to 61967 MUg kg-1 and the cancer risk values for the eight sections of Indian population ranged between 7.63E-10 to 5.05E+00, indicating product specific distribution of risk from non-significant to significant levels. Cereals, vegetables and decoctions contributed majorly to cancer risk and the most susceptible group identified was children. The spread of risk estimates followed Burr and Exponential distributions. To the best of our knowledge, this is the first study to develop information on the health risk faced by Indian population through dietary PAHs. PMID- 29574391 TI - A novel evaluation of the effect of lanthanum exposure on plant populations. AB - : The accumulation of rare earth elements (REEs) in the environment has recently become a new environmental problem. There have been many studies about the effects of REEs on plant at the individual, organ, cellular and genetic levels. Plants exist in populations under natural conditions, but little is known about the effects of REEs on plant populations. In this study, the effects of lanthanum (III) [La(III)] on the root module growth of soybean (Glycine max L) populations at different densities were investigated by simulating La(III) pollution. Results showed that at La(III) concentrations of 0.40 and 1.20 mM, both the root module growth parameters and leaf photosynthesis parameters were decreased, with 1.20 mM of La(III) causing a more significant decrease. In addition, the above parameters in low-density soybean populations decreased more significantly than those in high-density soybean populations. The above results show that the inhibitory effects of 0.40 and 1.20 mM of La(III) on the growth of root modules are closely related to the inhibition of photosynthesis in soybean population. Moreover, the inhibitory effect of La(III) on the growth of root modules of soybean population is enhanced as the La(III) concentration increases, while is weakened as plant population density increases. This study would provide a reference for the further research on the ecotoxicology of REEs, and show a new perspective and basis for the objective assessment of the environmental risks of REEs. ONE SENTENCE SUMMARY: La(III) pollution affects the root module growth and photosynthesis in soybean populations, and the effects vary depending on soybean population densities. PMID- 29574392 TI - The influence of carbon-encapsulated iron nanoparticles on elastic modulus of living human mesenchymal stem cells examined by atomic force microscopy. AB - Nanomaterials and nanoparticles are regarded as promising candidates for various biomedical applications due to their unique physicochemical properties. In this study, three types of carbon-encapsulated iron nanoparticles (CEINs) were synthesized and their impact on cellular changes was investigated by atomic force microscopy (AFM). The AFM experiment was additionally compared with conventional methods, such as colorimetric assay and other microscopic techniques. A significant difference of reduced Young's modulus of the cells was revealed, even at low concentration of nanoparticles in the culture medium. The AFM measurement proved to be a useful tool not only for visualization, but also for identification of local cellular changes at the nanoscale after exposure to carbon-encapsulated iron nanoparticles. PMID- 29574393 TI - The performance of one-step nucleic acid amplification assay for intraoperative detection of sentinel lymph node macrometastasis in breast cancer: An updated meta-analysis. AB - BACKGROUND: One-step nucleic acid amplification (OSNA) assay is a molecular diagnostic method for intraoperative detection of lymph node metastasis by amplifying cytokeratin 19 mRNA. We aim to further evaluate the performance of OSNA assay for the intraoperative diagnosis of sentinel lymph node metastasis in breast cancer. METHODS: PubMed, Cochrane Library, Web of Science databases were searched to retrieve related literature published up until December 2017. This meta-analysis was performed using a random-effects model. Risks of bias and quality assessments of included studies were evaluated and subgroup analysis was performed. RESULTS: Nineteen studies were included in this meta-analysis. For overall metastasis, the pooled sensitivity, specificity and area under the summary receiver-operating characteristic curve (AUC) were 0.90, 0.96 and 0.98, respectively. For macrometastasis, the pooled sensitivity, specificity and AUC were 0.85, 0.98 and 0.94, respectively. CONCLUSION: OSNA assay is an accurate molecular diagnosis for intraoperative detection of sentinel lymph node macrometastasis in breast cancer. PMID- 29574394 TI - Online learning versus blended learning of clinical supervisee skills with pre registration nursing students: A randomised controlled trial. AB - BACKGROUND: The World Health Organisation amongst others recognises the need for the introduction of clinical supervision education in health professional education as a central strategy for improving patient safety and patient care. Online and blended learning methods are growing exponentially in use in higher education and the systematic evaluation of these methods will aid understanding of how best to teach clinical supervision. OBJECTIVE: The purpose of this study was to test whether undergraduate nursing students who received clinical supervisee skills training via a blended learning approach would score higher in terms of motivation and attitudes towards clinical supervision, knowledge of clinical supervision and satisfaction of learning method, when compared to those students who received an online only teaching approach. DESIGN: A post-test-only randomised controlled trial. METHODS: Participants were a total of 122 pre registration nurses enrolled at one United Kingdom university, randomly assigned to the online learning control group (n = 60) or the blended learning intervention group (n = 62). The blended learning intervention group participated in a face-to-face tutorial and the online clinical supervisee skills training app. The online learning control group participated in an online discussion forum and the same online clinical supervisee skills training app. The outcome measures were motivation and attitudes using the modified Manchester Clinical Supervision Scale, knowledge using a 10 point Multiple Choice Questionnaire and satisfaction using a university training evaluation tool. Statistical analysis was performed using independent t-tests to compare the differences between the means of the control group and the intervention group. Thematic analysis was used to analyse responses to open-ended questions. RESULTS: All three of our study hypotheses were confirmed. Participants who received clinical supervisee skills training via a blended learning approach scored higher in terms of motivation and attitudes - mean (m) = 85.5, standard deviation (sd) = 9.78, number of participants (n) = 62 compared to the online group (m = 79.5, sd = 9.69, n = 60) (p = .001). The blended learning group also scored higher in terms of knowledge (m = 4.2, sd = 1.43, n = 56) compared to the online group (m = 3.51, sd = 1.51, n = 57) (p = .015); and in terms of satisfaction (m = 30.89, sd = 6.54, n = 57) compared to the online group (m = 26.49, sd = 6.93, n = 55) (p = .001). Qualitative data supported results. CONCLUSION: Blended learning provides added pedagogical value when compared to online learning in terms of teaching undergraduate nurses clinical supervision skills. The evidence is timely given worldwide calls for expanding clinical skills supervision in undergraduate health professional education to improve quality of care and patient safety. PMID- 29574395 TI - Acute myeloid leukemia induction with cladribine: Outcomes by age and leukemia risk. AB - Acute myeloid leukemia (AML) induction traditionally includes seven days of cytarabine and three days of an anthracycline (7 + 3). Because of evidence of increased efficacy of cladribine combined with this regimen, we conducted a retrospective analysis of 107 AML patients treated with idarubicin, cytarabine and cladribine (IAC) at our institution. Complete remission (CR) occurred in 71%, with overall response of 79%. One-year survival overall was 59%, with 47% (27/57) among patients >=60 years old and 72% (36/50) in those <60 (Relative Risk [RR] 1.9, 95% CI 1.2-3.2). Median overall survival was 17.3 months in all patients and Cox proportional hazard ratio (HR) for death was 2.2 (95% CI 1.3-3.6) for age >=60 years compared to <60 years. One year survival was 100% among favorable NCCN risk patients versus 64% in intermediate-risk and 35% in poor-risk patients (p < 0.001). HR for death in intermediate- risk (4.2, 95% CI 1.5-12) and poor-risk (8.4, 95% CI 3.0-24) compared to favorable risk AML was higher than that associated with age >=60 years (HR 2.2). We conclude that IAC is an effective AML induction regimen, NCCN leukemia risk predicts survival better than age in our population, and high intensity regimens can be justified in selected older patients. PMID- 29574396 TI - Comparison of intensive, pediatric-inspired therapy with non-intensive therapy in older adults aged 55-65 years with Philadelphia chromosome-negative acute lymphoblastic leukemia. AB - BACKGROUND AND OBJECTIVE: The standardization of treatment of older adults with Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) is challenging, especially in the age range of 55-65 years. This study aimed to compare intensive, pediatric-inspired therapy with non-intensive therapy in this population of patients. PATIENTS AND METHODS: The outcomes of 67 patients prospectively included in two consecutive pediatric-inspired intensive protocols (ALL-HR03 and ALL-HR11) from the Spanish PETHEMA Group were compared with those from 44 patients included in a contemporary semi-intensive protocol (ALL-OLD07). RESULTS: Baseline patient and ALL characteristics were similar in both groups, except for a younger median age in the intensive group (medians: 58 vs. 62 years). Patients treated intensively had a higher complete remission rate (85% vs. 64%, p = 0.005), a lower cumulative incidence of relapse (39% [95%CI, 25% to 52%] vs. 60% [95%CI, 38% to 77%], p = .003), a similar cumulative incidence of treatment-related mortality (28% [95% CI, 18%, 40%] vs. 21% [95% CI, 10%, 34%]) and superior event-free survival at 2 years (37% [95%CI, 25%-49%) vs. 21% [8% 34%], p = 0.002). On multivariable analysis the type of protocol was the only variable with independent significance for event-free survival (HR [95% CI]: 2 [1.3, 3], p = .002). CONCLUSIONS: Compared with less intensive chemotherapy, pediatric-inspired intensive chemotherapy significantly improves the outcome of older adults with Ph-negative ALL in the age range of 55-65 years. PMID- 29574397 TI - High frequency of dicentric chromosomes detected by multi-centromeric FISH in patients with acute myeloid leukemia and complex karyotype. AB - Dicentric chromosomes (DCs) are considered markers of cancer in various malignancies. However, they can be overlooked when conventional analysis or multicolor fluorescence in situ hybridization (mFISH) is used to detect complex karyotypes. We analyzed the karyotypes of 114 patients with acute myeloid leukemia (AML) and complex karyotypes and verified the presence of monosomies by FISH using multi-centromeric probes. Monosomy was detected in 63% of patients by G-banding/mFISH and confirmed in 55% of patients by centromeric FISH. FISH analysis indicated a high frequency of DCs that were previously considered monosomies. In some cases, it was apparent that the derivative monocentric chromosome was a primary DC. DCs were formed mostly by chromosomes 17 and 20. In conclusion, chromosome loss and unbalanced translocation suggest the presence of a hidden DC or its previous existence. DCs undergo several stabilizing changes and can induce other chromosomal aberrations and/or the formation of new DCs. This can result in the clonal evolution of abnormal cells, which is considered an independent prognostic marker of an unfavorable disease course and short survival. PMID- 29574398 TI - Heterogeneous Multifrequency Direct Inversion (HMDI) for magnetic resonance elastography with application to a clinical brain exam. AB - A new viscoelastic wave inversion method for MRE, called Heterogeneous Multifrequency Direct Inversion (HMDI), was developed which accommodates heterogeneous elasticity within a direct inversion (DI) by incorporating first order gradients and combining results from a narrow band of multiple frequencies. The method is compared with a Helmholtz-type DI, Multifrequency Dual Elasto-Visco inversion (MDEV), both on ground-truth Finite Element Method simulations at varied noise levels and a prospective in vivo brain cohort of 48 subjects ages 18 65. In simulated data, MDEV recovered background material within 5% and HMDI within 1% of prescribed up to SNR of 20 dB. In vivo HMDI and MDEV were then combined with segmentation from SPM to create a fully automated "brain palpation" exam for both whole brain (WB), and brain white matter (WM), measuring two parameters, the complex modulus magnitude |G*| , which measures tissue "stiffness", and the slope of |G*| values across frequencies, a measure of viscous dispersion. |G*| values for MDEV and HMDI were comparable to the literature (for a 3-frequency set centered at 50 Hz, WB means were 2.17 and 2.15 kPa respectively, and WM means were 2.47 and 2.49 kPa respectively). Both methods showed moderate correlation to age in both WB and WM, for both |G*| and |G*| slope, with Pearson's r >= 0.4 in the most sensitive frequency sets. In comparison to MDEV, HMDI showed better preservation of recovered target shapes, more noise-robustness, and stabler recovery values in regions with rapid property change, however summary statistics for both methods were quite similar. By eliminating homogeneity assumptions within a fast, fully automatic, regularization-free direct inversion, HMDI appears to be a worthwhile addition to the MRE image reconstruction repertoire. In addition to supporting the literature showing decrease in brain viscoelasticity with age, our work supports a wide range of inter-individual variation in brain MRE results.

AB - Surface mapping methods play an important role in various brain imaging studies from tracking the maturation of adolescent brains to mapping gray matter atrophy patterns in Alzheimer's disease. Popular surface mapping approaches based on spherical registration, however, have inherent numerical limitations when severe metric distortions are present during the spherical parameterization step. In this paper, we propose a novel computational framework for intrinsic surface mapping in the Laplace-Beltrami (LB) embedding space based on Riemannian metric optimization on surfaces (RMOS). Given a diffeomorphism between two surfaces, an isometry can be defined using the pullback metric, which in turn results in identical LB embeddings from the two surfaces. The proposed RMOS approach builds upon this mathematical foundation and achieves general feature-driven surface mapping in the LB embedding space by iteratively optimizing the Riemannian metric defined on the edges of triangular meshes. At the core of our framework is an optimization engine that converts an energy function for surface mapping into a distance measure in the LB embedding space, which can be effectively optimized using gradients of the LB eigen-system with respect to the Riemannian metrics. In the experimental results, we compare the RMOS algorithm with spherical registration using large-scale brain imaging data, and show that RMOS achieves superior performance in the prediction of hippocampal subfields and cortical gyral labels, and the holistic mapping of striatal surfaces for the construction of a striatal connectivity atlas from substantia nigra.

AB - INTRODUCTION: Ectopic or heterotopic pancreas is a congenital disorder defined as abnormally located pancreatic tissue found outside the pancreatic frame. It is a rare entity that occasionally causes symptoms depending on its location. PRESENTATION OF CASE: We present the case of an incidental finding of proximal jejunal ectopic pancreas in a middle-aged woman presenting with appendicitis. DISCUSSION AND CONCLUSION: Although rare it is necessary to be aware that jejunal ectopic pancreas can lead to jejunojejunal intussusception.

However, there is few data to support its role in the elderly. The primary aim of this study was to evaluate whether subjects with late life depression (LLD) presented with changes in oxidative stress response in comparison with the non-depressed control group. We then explored how oxidative stress markers associated with specific features of LLD, in particular cognitive performance and age of onset of major depressive disorder in these individuals. METHODS: We included a convenience sample of 124 individuals, 77 with LLD and 47 non-depressed subjects (Controls). We measure the plasma levels of 6 oxidative stress markers: thiobarbituric acid reactive substances (TBARS), protein carbonil content (PCC), free 8-isoprostane, glutathione peroxidase (GPx) activity, glutathione reductase (GR) activity, and glutathione S-transferase (GST) activity. RESULTS: We found that participants with LLD had significantly higher free 8-isoprostane levels (p = 0.003) and lower glutathione peroxidase activity (p = 0.006) compared to controls. Free 8-isoprostane levels were also significantly correlated with worse scores in the initiation/perseverance (r = 0.24, p = 0.01), conceptualization (r = -0.22, p = 0.02) sub-scores, and the total scores (r = -0.21, p = 0.04) on the DRS. CONCLUSIONS: Our study provides robust evidence of the imbalance between oxidative stress damage, in particular lipid peroxidation, and anti-oxidative defenses as a mechanism related to LLD, and cognitive impairment in this population. Interventions aiming to reduce oxidative stress damage can have a potential neuroprotective effect for LLD subjects.

AB - OBJECTIVES: Meta-analyses are considered generally as the highest level of evidence, but concerns have been voiced about their massive, low-quality production. This paper aimed to evaluate the landscape of meta-analyses in the field of occupational and environmental health and medicine. METHODS: Using relevant search terms, all meta-analyses were searched for, but those published in 2015 were assessed for their origin, whether they included randomised trials and individual-level data and whether they had authors from the industry or consultancy firms. RESULTS: PubMed searches (last update February 2017) identified 1251 eligible meta-analyses in this field. There was a rapid increase over time (n=16 published in 1995 vs n=163 published in 2015). Of the 163 eligible meta-analyses published in 2015, 49 were from China, followed at a distance by the USA (n=19). Only 16 considered randomised (intervention) trials and 13 included individual-level data. Only 1 of the 150 meta-analyses had industry authors and none had consultancy firm authors. As an example of conflicting findings, 12 overlapping meta-analyses addressed mobile phones and brain cancer risk and they differed substantially in number of studies included, eligibility criteria and conclusions. CONCLUSIONS: There has been a major increase in the publication of meta-analyses in occupational and environmental health over time, with the majority of these studies focusing on observational data, while a commendable fraction used individual-level data. Authorship is still limited largely to academic and non-profit authors. With massive production of meta-analyses, redundancy needs to be anticipated and efforts should be made to safeguard quality and protect from bias.

PMID- 29574409 TI - A cohort study reporting normal oximetry values in healthy infants under 4 months of age using Masimo technology. AB - OBJECTIVE: To determine sleeping saturation indices in healthy infants using a modern pulse oximeter with motion artefact extraction technology. DESIGN: Prospective cohort. SETTING: Home. SUBJECTS: Healthy term infants. INTERVENTION: Nocturnal pulse oximetry at home at 1 month of age (Recording 1) and repeated at age 3-4 months (Recording 2). Parents documented sleep times. Visi-Download software (Stowood Scientific) analysed data with artefact and wake periods removed. MAIN OUTCOME MEASURES: Saturations (SAT50), desaturation index >4% (DI4) and >3% (DI3) from baseline/hour, delta index 12 s (DI12s), minimum saturations (SATmin), percentage time with saturations below 90% and 92%. RESULTS: Forty-five babies were studied at 1 month and 38 babies at 3-4 months. Mean (CI) SAT50, DI4, DI3, DI12s and SATmin (CI) were 97.05 (96.59 to 97.52), 16.16 (13.72 to 18.59), 25.41 (22.00 to 28.82), 0.96 (0.88 to 1.04) and 80.4% (78.8% to 82.0%) at 1 month, respectively, and 97.65 (97.19 to 98.12), 8.12 (6.46 to 9.77), 13.92 (11.38 to 16.47), 0.72 (0.65 to 0.78) and 84.7% (83.3% to 86.1%) at 3-4 months. Median (CI) percentage times with saturations below 90% and 92% were 0.39 (0.26 to 0.55) and 0.82 (0.60 to 1.23), respectively, at 1 month and 0.11 (0.06 to 0.20) and 0.25 (0.17 to 0.44) at 3-4 months. For paired samples (n=32) DI4 (P=0.006), DI3 (P=0.03), DI12s (P=0.001), percentage time with saturations below 90% (P=0.001) and 92% (P=0.000) all fell significantly and SATmin (P=0.004) rose between the two recordings. CONCLUSION: Desaturation indices are substantially higher in young infants than older children where a DI4 over 4 is considered abnormal. These decrease by 3-4 months of age but still remain elevated compared with older children. PMID- 29574410 TI - Genomics for paediatricians: promises and pitfalls. AB - In recent years, there have been significant advances in genetic technologies, evolving the field of genomics from genetics. This has huge diagnostic potential, as genomic testing increasingly becomes part of mainstream medicine. However, there are numerous potential pitfalls in the interpretation of genomic data. It is therefore essential that we educate clinicians more widely about the appropriate interpretation and utilisation of genomic testing.

AB - OBJECTIVES: We aimed to analyse outcomes of ticagrelor and clopidogrel stratified by estimated glomerular filtration rate (eGFR) in a large unselected cohort of patients with acute myocardial infarction (MI). METHODS: We used follow-up data in MI survivors discharged on ticagrelor or clopidogrel enrolled in the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies registry. The association between ticagrelor versus clopidogrel and the primary composite outcome of death, MI or stroke and the secondary outcome rehospitalisation with bleeding diagnosis at 1 year, was studied using adjusted Cox proportional hazards models, stratifying after eGFR levels. RESULTS: In total, 45 206 patients with MI discharged on clopidogrel (n=33 472) or ticagrelor (n=11 734) were included. The unadjusted 1-year event rate for the composite endpoint of death, MI or stroke was 7.0%, 18.0% and 48.0% for ticagrelor treatment and 11.0%, 33.0% and 64.0% for clopidogrel treatment in patients with eGFR>60 (n=33 668), eGFR30-60 (n=9803) and eGFR<30 (n=1735), respectively. After adjustment, ticagrelor as compared with clopidogrel was associated with a lower 1-year risk of the composite outcome (eGFR>60: HR 0.87, 95% CI 0.76 to 99, eGFR30-60: 0.82 (0.70 to 0.97), eGFR<30: 0.95 (0.69 to 1.29), P for interaction=0.55) and a higher risk of bleeding (eGFR>60: HR 1.10, 95% CI 0.90 to 1.35, eGFR30-60: 1.13 (0.84 to 1.51), eGFR<30: 1.79 (1.00 to 3.21), P for interaction=0.30) across the eGFR strata. CONCLUSIONS: Treatment with ticagrelor as compared with clopidogrel in patients with MI was associated with lower risk for the composite of death, MI or stroke and a higher bleeding risk across all strata of eGFR. Of caution, bleeding events were more abundant in patients with eGFR<30. PMID- 29574414 TI - Lack of standardisation of ANA and implications for drug development and precision medicine.

PMID- 29574408 TI - European evidence-based guidelines on pancreatic cystic neoplasms. AB - Evidence-based guidelines on the management of pancreatic cystic neoplasms (PCN) are lacking. This guideline is a joint initiative of the European Study Group on Cystic Tumours of the Pancreas, United European Gastroenterology, European Pancreatic Club, European-African Hepato-Pancreato-Biliary Association, European Digestive Surgery, and the European Society of Gastrointestinal Endoscopy. It replaces the 2013 European consensus statement guidelines on PCN. European and non-European experts performed systematic reviews and used GRADE methodology to answer relevant clinical questions on nine topics (biomarkers, radiology, endoscopy, intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), serous cystic neoplasm, rare cysts, (neo)adjuvant treatment, and pathology). Recommendations include conservative management, relative and absolute indications for surgery. A conservative approach is recommended for asymptomatic MCN and IPMN measuring <40 mm without an enhancing nodule. Relative indications for surgery in IPMN include a main pancreatic duct (MPD) diameter between 5 and 9.9 mm or a cyst diameter >=40 mm. Absolute indications for surgery in IPMN, due to the high-risk of malignant transformation, include jaundice, an enhancing mural nodule >5 mm, and MPD diameter >10 mm. Lifelong follow-up of IPMN is recommended in patients who are fit for surgery. The European evidence-based guidelines on PCN aim to improve the diagnosis and management of PCN.

PMID- 29574416 TI - Occupational exposures and 20-year incidence of COPD: the European Community Respiratory Health Survey. AB - BACKGROUND: Occupational exposures have been associated with an increased risk of COPD. However, few studies have related objectively assessed occupational exposures to prospectively assessed incidence of COPD, using postbronchodilator lung function tests. Our objective was to examine the effect of occupational exposures on COPD incidence in the European Community Respiratory Health Survey. METHODS: General population samples aged 20-44 were randomly selected in 1991 1993 and followed up 20 years later (2010-2012). Spirometry was performed at baseline and at follow-up, with incident COPD defined using a lower limit of normal criterion for postbronchodilator FEV1/FVC. Only participants without COPD and without current asthma at baseline were included. Coded job histories during follow-up were linked to a Job-Exposure Matrix, generating occupational exposure estimates to 12 categories of agents. Their association with COPD incidence was examined in log-binomial models fitted in a Bayesian framework. FINDINGS: 3343 participants fulfilled the inclusion criteria; 89 of them had COPD at follow-up (1.4 cases/1000 person-years). Participants exposed to biological dust had a higher incidence of COPD compared with those unexposed (relative risk (RR) 1.6, 95% CI 1.1 to 2.3), as did those exposed to gases and fumes (RR 1.5, 95% CI 1.0 to 2.2) and pesticides (RR 2.2, 95% CI 1.1 to 3.8). The combined population attributable fraction for these exposures was 21.0%. INTERPRETATION: These results substantially strengthen the evidence base for occupational exposures as an important risk factor for COPD. PMID- 29574419 TI - Facilitation of IL-22 production from innate lymphoid cells by prostaglandin E2 prevents experimental lung neutrophilic inflammation. AB - Acute lung injury is a neutrophil-dominant, life-threatening disease without effective therapies and better understanding of the pathophysiological mechanisms involved is an urgent need. Here we show that interleukin (IL)-22 is produced from innate lymphoid cells (ILC) and is responsible for suppression of experimental lung neutrophilic inflammation. Blocking prostaglandin E2 (PGE2) synthesis reduces lung ILCs and IL-22 production, resulting in exacerbation of lung neutrophilic inflammation. In contrast, activation of the PGE2 receptor EP4 prevents acute lung inflammation. We thus demonstrate a mechanism for production of innate IL-22 in the lung during acute injury, highlighting potential therapeutic strategies for control of lung neutrophilic inflammation by targeting the PGE2/ILC/IL-22 axis. PMID- 29574420 TI - Fifteen-minute consultation: Developing an advance care plan in partnership with the child and family. AB - An advance care plan (ACP) is the record of a discussion between an individual (where possible), their professional care givers and those close to them about their future care. When performed well, the process provides all those involved with the opportunity to talk honestly about the future allowing children and their families to retain autonomy and to influence how they are looked after. While this may represent a difficult area of practice for healthcare professionals, both staff and families appear to benefit when the process is fully informed and the child and family are actively involved. This article is enriched by the insight of two bereaved parents, who have engaged actively with the process of advance care planning. As a multidisciplinary writing team, we aim to share our experiences, in the context of recent national guidance, on the use of ACPs. PMID- 29574421 TI - Thrombectomy using the EmboTrap device: core laboratory-assessed results in 201 consecutive patients in a real-world setting. AB - BACKGROUND: We studied patients treated with the EmboTrap revascularization device in a prospective registry which is core laboratory evaluated by physicians from external centers. The goal was to determine how the EmboTrap would perform under the everyday conditions of a high-volume stroke center. METHODS: We examined all patients with acute stroke treated with the Embotrap device from October 2013 to March 2017 in our center. Imaging parameters and times were adjudicated by core laboratory personnel blinded to clinical information, treating physician, and clinical outcomes. Clinical evaluation was performed by independent neurologists and entered in a national registry. Evaluated endpoints were: successful revascularization (modified Thrombolysis in Cerebral Infarction (mTICI) 2b-3) and good clinical outcomes at 3 months (modified Rankin Scale (mRS) 0-2). RESULTS: 201 consecutive patients with a median NIH Stroke Scale (NIHSS) score of 15 (range 2-30) were included. 170 patients (84.6%) achieved mTICI 2b-3 reperfusion. The median number of attempts was 2 (range 1-10) with 52.8% of the population achieving good functional outcomes (mRS 0-2) at 3 months. On univariate analysis, good functional outcome was associated with the number of attempts, puncture-to-reperfusion time, anterior circulation occlusion, and NIHSS score. On multivariate analysis, pre-treatment NIHSS (OR 0.845 per point, 95% CI 0.793 to 0.908, P<0.001) and puncture-to-reperfusion time (OR 0.9952 per min, 95% CI 0.9914 to 0.9975, P=0.023) were associated with good functional outcomes at 3 months. CONCLUSION: The Embotrap device has a high rate of successful reperfusion. Our core laboratory-audited single-center experience suggests the technical feasibility and safety of the Embotrap for first-line use in a real world setting. PMID- 29574423 TI - Palliative stenting for oesophagogastric cancer: tumour and host factors and prognosis. AB - OBJECTIVES: Palliative self-expandable metallic stent (SEMS) insertion is common in patients not suitable for resection of oesophagogastric (OG) cancer. Factors which may determine survival, however, are not clear. The present study examined the relationship between tumour and host factors, including the systemic inflammatory response and survival of patients undergoing palliative SEMS insertion. METHODS: Patients with a diagnosis of OG cancer who were considered suitable for palliative SEMS only without systemic therapy were identified. Patient characteristics including Eastern Cooperative Oncology Group performance status, radiological stage and modified Glasgow Prognostic Score (mGPS: 0-C reactive protein (CRP) <=10 mg/L; 1-CRP >10 mg/L; 2-CRP >10 mg/L; albumin <35 g/L) were recorded prospectively. The relationship between such characteristics and 3-month survival was examined. RESULTS: 203 patients were included in the final analysis. All patients died during follow-up, with median survival from diagnosis 75 days (IQR 47-157). 78% of patients were systemically inflamed (mGPS >1). On multivariate analysis, only poor performance status (HR 1.23, p=0.025), metastatic disease (HR 2.27, p<0.001) and mGPS (HR 1.25, p=0.021) were associated with shorter survival. The combination of performance status and mGPS stratified 3-month survival of patients without metastatic disease from 88% to 20% (p<0.001) and patients with metastases from 43% to 6% (p=0.059). Similar results were observed when analysis was restricted to patients with oesophageal and junctional cancer (M0: 83%-20%, p=0.008; M1: 33%-8%, p=0.082). CONCLUSION: Performance status, metastatic disease and mGPS are independent predictors of survival in patients with OG cancer undergoing palliative SEMS insertion. These routinely available markers provide a rational system on which to base decisions regarding prognosis and treatment. PMID- 29574422 TI - Maternal variants in NLRP and other maternal effect proteins are associated with multilocus imprinting disturbance in offspring. AB - BACKGROUND: Genomic imprinting results from the resistance of germline epigenetic marks to reprogramming in the early embryo for a small number of mammalian genes. Genetic, epigenetic or environmental insults that prevent imprints from evading reprogramming may result in imprinting disorders, which impact growth, development, behaviour and metabolism. We aimed to identify genetic defects causing imprinting disorders by whole-exome sequencing in families with one or more members affected by multilocus imprinting disturbance. METHODS: Whole-exome sequencing was performed in 38 pedigrees where probands had multilocus imprinting disturbance, in five of whom maternal variants in NLRP5 have previously been found. RESULTS: We now report 15 further pedigrees in which offspring had disturbance of imprinting, while their mothers had rare, predicted-deleterious variants in maternal effect genes, including NLRP2, NLRP7 and PADI6. As well as clinical features of well-recognised imprinting disorders, some offspring had additional features including developmental delay, behavioural problems and discordant monozygotic twinning, while some mothers had reproductive problems including pregnancy loss. CONCLUSION: The identification of 20 putative maternal effect variants in 38 families affected by multilocus imprinting disorders adds to the evidence that maternal genetic factors affect oocyte fitness and thus offspring development. Testing for maternal-effect genetic variants should be considered in families affected by atypical imprinting disorders. PMID- 29574424 TI - Why we need more poetry in palliative care. AB - OBJECTIVES: Although many well-known poems consider illness, loss and bereavement, medicine tends to view poetry more as an extracurricular than as a mainstream pursuit. Within palliative care, however, there has been a long standing interest in how poetry may help patients and health professionals find meaning, solace and enjoyment. The objective of this paper is to identify the different ways in which poetry has been used in palliative care and reflect on their further potential for education, practice and research. METHODS: A narrative review approach was used, drawing on searches of the academic literature through Medline and on professional, policy and poetry websites to identify themes for using poetry in palliative care. RESULTS: I identified four themes for using poetry in palliative care. These concerned (1) leadership, (2) developing organisational culture, (3) the training of health professionals and (4) the support of people with serious illness or nearing the end of life. The academic literature was mostly made up of practitioner perspectives, case examples or conceptual pieces on poetry therapy. Patients' accounts were rare but suggested poetry can help some people express powerful thoughts and emotions, create something new and feel part of a community. CONCLUSION: Poetry is one way in which many people, including patients and palliative care professionals, may seek meaning from and make sense of serious illnesses and losses towards the end of life. It may have untapped potential for developing person-centred organisations, training health professionals, supporting patients and for promoting public engagement in palliative care. PMID- 29574425 TI - Blood transfusion practice in the UK and Ireland: a survey of palliative care physicians. AB - OBJECTIVES: Red cell (blood) transfusions are used in palliative care to manage patients with symptomatic anaemia or when patients have lost blood. We aimed to understand current blood transfusion practice among palliative medicine doctors and compare this with National Institute for Health and Care Excellence (NICE) guidance. NICE guidance advocates more restrictive transfusion practice but is based on clinical trials in non-palliative care contexts; the extent to which these findings should be applied to palliative care remains unclear. METHODS: Four clinical vignettes of common clinical palliative care scenarios were developed. Members of the Association for Palliative Medicine were invited to complete the survey. Results were compared with acceptable responses based on current NICE recommendations and analysed to determine the influence of respondents' gender, experience or work setting. RESULTS: 27% of 1070 members responded. Overall, ideal or acceptable responses were selected by less than half of doctors to all four vignettes. Doctors were more liberal in prescribing blood transfusions than NICE guidance would advocate. Senior doctors were less likely to choose an acceptable response than junior colleagues. CONCLUSION: Palliative care practice is varied and not consistent with a restrictive blood transfusion policy. More recently trained doctors follow less liberal practices than senior colleagues. More direct evidence of benefits and harms of blood transfusion is needed in palliative care to inform practice. PMID- 29574426 TI - Delayed neurological deficits after endovascular placement of a pipeline embolisation device: clinical manifestation and treatment. AB - Endovascular treatment has been the mainstay of therapy for repair of both ruptured and unruptured cerebral aneurysms. Flow diverter devices offer a new option for the treatment of complex aneurysms that were previously not amenable to coiling. Procedural adverse effects include intracranial haemorrhage and ischaemic stroke, which usually occur on the same day. Delayed complications are rare. We report a case of a patient who underwent placement of a pipeline embolisation device and developed delayed neurological deficits, which were thought to be an inflammatory reaction to the hydrophilic coating used in guidewires and microcatheters. Our patient was treated with a course of steroids, with improvement of her neurological deficits and resolution of MRI findings. As the use of flow diverter devices has increased, variable and delayed complications of such therapy are increasingly being reported in the literature. PMID- 29574427 TI - Septic presentation of a giant fibroepithelial polyp of the vulva. AB - Fibroepithelial stromal polyps are mesenchymal lesions occurring typically in reproductive age women with a predilection for the vulvo-vaginal region. Malignancy may mimic this polyp in morphology, rendering further investigations including detailed histopathology mandatory. Histologically its characteristic features are stellate and multinucleate stromal cells identified near the epithelial-stromal interface. This case report discusses incidental finding of largest fibroepithelial polyp presented in a 31-year-old nulliparous woman. She was initially admitted with sepsis and detailed physical examination revealed a right-sided infected pedunculated labial mass measuring 20*21 cm. After initial resuscitation for sepsis, she was further investigated for the mass. Transabdominal ultrasound was essentially normal apart from a small fibroid 3*2 cm in the anterior wall of the uterus. The vulval mass was removed under local and regional anaesthesia and was confirmed to be a giant fibroepithelial stromal polyp on histopathology. The woman recovered well and was followed up until 1 year. PMID- 29574428 TI - Thyrotoxic crisis as an acute clinical presentation in a child. AB - A previously well, 4-year-old girl presented with a 4-6 weeks' history of increased appetite, weight loss, tiredness, sleep difficulty, excessive sweating, swelling in the neck and new-onset 'prominent, protruding eyes.' Family history revealed paternal grandmother receiving treatment for hyperthyroidism. Clinical assessment demonstrated features of thyrotoxicosis (tachycardia, warm peripheries, small smooth goitre with no nodules, exophthalmos). TFT (Free T4=101 pmol/L, thyroid-stimulating hormone <0.05 mIU/L) with raised thyroid peroxidase antibody levels (TPO=541 IU/mL) confirmed autoimmune hyperthyroidism. Observation on the ward showed features of thyrotoxic crisis with persistent severe tachycardia on ECG (sinus tachycardia with left ventricular hypertrophy (LVH)) and hypertension. Ultrasound thyroid showed diffuse thyroiditis with no focal lesion. Echocardiogram confirmed the above findings. A diagnosis of Graves' disease with thyrotoxic crisis was made. Antithyroid treatment (carbimazole) and beta-blocker (propranolol) was commenced. Thyrotoxic crisis resolved over 2 weeks and the child has continued to respond to carbimazole treatment at 1-year follow up. PMID- 29574429 TI - Placenta accreta complicated with peripartum cardiomyopathy. AB - A 33-year-old G2P1 was referred to our hospital due to placenta accreta. During perioperative preparations, the patient was diagnosed with having a peripartum cardiomyopathy. The patient underwent caesarean hysterectomy at 36 weeks with an associated 2 L blood loss. Haemodynamic maintenance and stabilisation during the operation were challenging, with the combinations of fluid therapy, blood transfusions as well as vasoactive, antifibrinolytic and haemostatic drug. Postoperatively, the patient was managed in the intensive care unit and was subsequently transferred to intermediate care after less than 24 hours' observation. She was stable enough to be moved to the obstetrics ward the next day. PMID- 29574430 TI - Rapidly expanding venous intracerebral haemorrhage with spot sign. AB - A 79-year-old woman was brought to the hospital with an acute-onset left haemiparesis. On initial examination, she had a pure sensorimotor syndrome with left-sided weakness and sensory disturbance. Her mental status was normal. She had normal visual fields to confrontation and no neglect. Her initial CT and CT angiogram revealed cerebral venous thrombosis with associated haemorrhage. A 'spot sign' was visible on CT angiogram. Immediately following the CT scan, the patient had a rapidly progressive decline in level of consciousness, requiring endotracheal intubation. A follow-up CT scan 70 min later showed the haemorrhage had expanded dramatically, with mass effect, midline shift and herniation. After a discussion with the family, the patient was extubated and died the following day. This is the first case of a cerebral venous thrombosis with associated spot sign-positive haemorrhage and published clinical details that the authors are aware of.

PMID- 29574432 TI - Primary male factor infertility due to asthenospermia in maturity-onset diabetes of the young type 5 (MODY 5): uncommon presentation of an uncommon disease. AB - Mutations in hepatocyte nuclear factor-1beta gene result in a multisystemic syndrome where a monogenic form of diabetes (maturity-onset diabetes of young type 5; MODY 5) and renal anomalies, usually bilateral multiple cysts are the most characteristic findings. Many of them have pancreatic structural abnormalities as well. A plethora of extrapancreatic manifestations like altered liver function tests, hypomagnesaemia, hyperuricaemia with/without gout and urogenital malformations, particularly in females are also components of the syndrome. Structural malformation of male urogenital tract is rare in MODY 5, even rarer is asthenospermia. We encountered a young non-obese individual having insulin-requiring diabetes following secondary oral agent failure with primary male factor infertility secondary to asthenospermia. A suggestive family history, lack of acanthosis, negative pancreatic autoimmunity, hypomagnesaemia, bilateral renal and epididymal cysts, and absence of body and tail of pancreas pointed towards underlying MODY 5. PMID- 29574433 TI - Concurrent Sweet's syndrome and myopericarditis following mesalamine therapy. AB - Mesalamine, or 5-aminosalicylic acid, is a frequently used medication for the treatment of inflammatory bowel disease (IBD). We report the case of a 40-year old woman recently diagnosed with IBD and started on mesalamine, who presented with new onset tender skin lesions 3 days following medication administration. One day following the onset of skin lesions, the patient developed acute chest pain, shortness of breath, ECG changes, troponemia, C-reactive protein elevation and pericardial enhancement on cardiac MRI consistent with myopericarditis. Subsequent skin biopsy confirmed the diagnosis of Sweet's syndrome. On cessation of the drug, both the skin lesions and the cardiac symptoms resolved in combination with anti-inflammatory therapy. While mesalamine has been previously associated with myocarditis and pericarditis, to our knowledge this is the first case of coexisting Sweet's syndrome with myopericarditis in the context of mesalamine therapy. PMID- 29574434 TI - Herpes zoster ophthalmicus evolving into headache characterised as hemicrania continua. AB - Postherpetic neuralgia (PHN) is the most common chronic complication of herpes zoster infection. However, a few patients may develop different types of pain after herpetic lesions. We are reporting two patients who developed postherpetic hemicrania continua (HC). Case 1: a 54-year-old woman had a 10-month history of continuous left-sided pain with superimposed exacerbations. The pain started with the onset of herpetic lesions in the ophthalmic division. The lesions subsided in a few weeks. However, the pain persisted and it responded exclusively to indomethacin. Case 2: a 61-year-old woman developed clinical features pertinent to PHN. However, later on, the pattern and associated clinical features changed. The patient fulfilled the criteria of HC and showed a complete response to indomethacin. We suggest that every patient with PHN should be asked for cranial autonomic features and a trial of indomethacin should be given in refractory herpes zoster neuropathy.

AIP can be associated with other autoimmune manifestations, including Sjogren's, inflammatory bowel disease, primary biliary cirrhosis, rheumatoid arthritis, hypothyroidism and sarcoidosis. Rarely, concurrent autoimmune haemolytic anaemia (AIHA) is observed, as seen in our case report of a 33-year-old postpartum woman.

AB - A 68-year-old man presented with rapid swelling of the right forehead 11 days after sustaining a laceration secondary to a fall. Presumed to be an abscess due to retained foreign body, needle aspiration was performed and arterial blood obtained. Doppler ultrasound revealed a 3 cm mixed echogenicity lesion with 'see sawing' internal Doppler flow arising from the superficial temporal artery (STA), in keeping with a pseudoaneurysm. Treatment options including interventional radiology and open surgery were considered. Open operative intervention with direct surgical ligation provided an excellent outcome. Delayed pseudoaneurysm of the STA is a rare complication of trauma but should be considered in the differential of a traumatic lateral forehead swelling to prevent complications and inappropriate investigations and management.

AB - OBJECTIVE: This paper describes the design and methods of a cluster randomised controlled trial (C-RCT) to determine the effectiveness of a community mobilisation intervention that is designed to reduce the perpetration of violence against women (VAW). METHODS AND ANALYSIS: A C-RCT of nine intervention and nine control clusters is being carried out in a periurban, semiformal settlement near Johannesburg, South Africa, between 2016 and 2018. A community mobilisation and advocacy intervention, called Sonke CHANGE is being implemented over 18 months. It comprises local advocacy and group activities to engage community members to challenge harmful gender norms and reduce VAW. The intervention is hypothesised to improve equitable masculinities, reduce alcohol use and ultimately, to reduce VAW. Intervention effectiveness will be determined through an audio computer assisted self-interview questionnaire with behavioural measures among 2600 men aged between 18 and 40 years at baseline, 12 months and 24 months. The primary trial outcome is men's use of physical and/or sexual VAW. Secondary outcomes include harmful alcohol use, gender attitudes, controlling behaviours, transactional sex and social cohesion. The main analysis will be intention-to treat based on the randomisation of clusters. A qualitative process evaluation is being conducted alongside the C-RCT. Implementers and men participating in the intervention will be interviewed longitudinally over the period of intervention implementation and observations of the workshops and other intervention activities are being carried out. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of the Witwatersrand Human Research Ethics Committee and procedures comply with ethical recommendations of the United Nations Multi Country Study on Men and Violence. Dissemination of research findings will take place with local stakeholders and through peer-reviewed publications, with data available on request or after 5 years of trial completion.

PMID- 29574439 TI - Randomised controlled trial of exercise to prevent shoulder problems in women undergoing breast cancer treatment: study protocol for the prevention of shoulder problems trial (UK PROSPER). AB - : Musculoskeletal shoulder problems are common after breast cancer treatment. Early postoperative exercises targeting the upper limb may improve shoulder function. This protocol describes a National Institute for Health Research-funded randomised controlled trial (RCT) to evaluate the clinical and cost-effectiveness of an early supervised structured exercise programme compared with usual care, for women at high risk of developing shoulder problems after breast cancer surgery. METHODS: This pragmatic two-armed, multicentre RCT is underway within secondary care in the UK. PRevention Of Shoulder ProblEms tRial (PROSPER) aims to recruit 350 women from approximately 15 UK centres with follow-up at 6 weeks, 6 and 12 months after randomisation. Recruitment processes and intervention development were optimised through qualitative research during a 6-month internal pilot phase. Participants are randomised to the PROSPER intervention or best practice usual care only. The PROSPER intervention is delivered by physiotherapists and incorporates three main components: shoulder-specific exercises targeting range of movement and strength; general physical activity and behavioural strategies to encourage adherence and support exercise behaviour. The primary outcome is upper arm function assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire at 12 months postrandomisation. Secondary outcomes include DASH subscales, acute and chronic pain, complications, health related quality of life and healthcare resource use. We will interview a subsample of 20 participants to explore their experiences of the trial interventions. DISCUSSION: The PROSPER study is the first multicentre UK clinical trial to investigate the clinical and cost-effectiveness of supported exercise in the prevention of shoulder problems in high-risk women undergoing breast cancer surgery. The findings will inform future clinical practice and provide valuable insight into the role of physiotherapy-supported exercise in breast cancer rehabilitation.

PMID- 29574440 TI - Projecting the effects of tobacco control policies in the USA through microsimulation: a study protocol. AB - INTRODUCTION: Smoking remains the leading cause of preventable death in the USA but can be reduced through policy interventions. Computational models of smoking can provide estimates of the projected impact of tobacco control policies and can be used to inform public health decision making. We outline a protocol for simulating the effects of tobacco policies on population health outcomes. METHODS AND ANALYSIS: We extend the Smoking History Generator (SHG), a microsimulation model based on data from the National Health Interview Surveys, to evaluate the effects of tobacco control policies on projections of smoking prevalence and mortality in the USA. The SHG simulates individual life trajectories including smoking initiation, cessation and mortality. We illustrate the application of the SHG policy module for four types of tobacco control policies at the national and state levels: smoke-free air laws, cigarette taxes, increasing tobacco control programme expenditures and raising the minimum age of legal access to tobacco. Smoking initiation and cessation rates are modified by age, birth cohort, gender and years since policy implementation. Initiation and cessation rate modifiers are adjusted for differences across age groups and the level of existing policy coverage. Smoking prevalence, the number of population deaths avoided, and life years gained are calculated for each policy scenario at the national and state levels. The model only considers direct individual benefits through reduced smoking and does not consider benefits through reduced exposure to secondhand smoke. ETHICS AND DISSEMINATION: A web-based interface is being developed to integrate the results of the simulations into a format that allows the user to explore the projected effects of tobacco control policies in the USA. Usability testing is being conducted in which experts provide feedback on the interface. Development of this tool is under way, and a publicly accessible website is available at http://www.tobaccopolicyeffects.org. PMID- 29574441 TI - Lifestyle and vascular risk effects on MRI-based biomarkers of Alzheimer's disease: a cross-sectional study of middle-aged adults from the broader New York City area. AB - OBJECTIVE: To investigate the effects of lifestyle and vascular-related risk factors for Alzheimer's disease (AD) on in vivo MRI-based brain atrophy in asymptomatic young to middle-aged adults. DESIGN: Cross-sectional, observational. SETTING: Broader New York City area. Two research centres affiliated with the Alzheimer's disease Core Center at New York University School of Medicine. PARTICIPANTS: We studied 116 cognitively normal healthy research participants aged 30-60 years, who completed a three-dimensional T1-weighted volumetric MRI and had lifestyle (diet, physical activity and intellectual enrichment), vascular risk (overweight, hypertension, insulin resistance, elevated cholesterol and homocysteine) and cognition (memory, executive function, language) data. Estimates of cortical thickness for entorhinal (EC), posterior cingulate, orbitofrontal, inferior and middle temporal cortex were obtained by use of automated segmentation tools. We applied confirmatory factor analysis and structural equation modelling to evaluate the associations between lifestyle, vascular risk, brain and cognition. RESULTS: Adherence to a Mediterranean-style diet (MeDi) and insulin sensitivity were both positively associated with MRI based cortical thickness (diet: betas>=0.26, insulin sensitivity betas>=0.58, P<=0.008). After accounting for vascular risk, EC in turn explained variance in memory (P<=0.001). None of the other lifestyle and vascular risk variables were associated with brain thickness. In addition, the path associations between intellectual enrichment and better cognition were significant (betas>=0.25 P<=0.001), as were those between overweight and lower cognition (betas>=-0.22, P<=0.01). CONCLUSIONS: In cognitively normal middle-aged adults, MeDi and insulin sensitivity explained cortical thickness in key brain regions for AD, and EC thickness predicted memory performance in turn. Intellectual activity and overweight were associated with cognitive performance through different pathways. Our findings support further investigation of lifestyle and vascular risk factor modification against brain ageing and AD. More studies with larger samples are needed to replicate these research findings in more diverse, community-based settings. PMID- 29574442 TI - Development of the Combined Assessment of Risk Encountered in Surgery (CARES) surgical risk calculator for prediction of postsurgical mortality and need for intensive care unit admission risk: a single-center retrospective study. AB - INTRODUCTION: Accurate surgical risk prediction is paramount in clinical shared decision making. Existing risk calculators have limited value in local practice due to lack of validation, complexities and inclusion of non-routine variables. OBJECTIVE: We aim to develop a simple, locally derived and validated surgical risk calculator predicting 30-day postsurgical mortality and need for intensive care unit (ICU) stay (>24 hours) based on routinely collected preoperative variables. We postulate that accuracy of a clinical history-based scoring tool could be improved by including readily available investigations, such as haemoglobin level and red cell distribution width. METHODOLOGY: Electronic medical records of 90 785 patients, who underwent non-cardiac and non-neuro surgery between 1 January 2012 and 31 October 2016 in Singapore General Hospital, were retrospectively analysed. Patient demographics, comorbidities, laboratory results, surgical priority and surgical risk were collected. Outcome measures were death within 30 days after surgery and ICU admission. After excluding patients with missing data, the final data set consisted of 79 914 cases, which was divided randomly into derivation (70%) and validation cohort (30%). Multivariable logistic regression analysis was used to construct a single model predicting both outcomes using Odds Ratio (OR) of the risk variables. The ORs were then assigned ranks, which were subsequently used to construct the calculator. RESULTS: Observed mortality was 0.6%. The Combined Assessment of Risk Encountered in Surgery (CARES) surgical risk calculator, consisting of nine variables, was constructed. The area under the receiver operating curve (AUROC) in the derivation and validation cohorts for mortality were 0.934 (0.917-0.950) and 0.934 (0.912-0.956), respectively, while the AUROC for ICU admission was 0.863 (0.848-0.878) and 0.837 (0.808-0.868), respectively. CARES also performed better than the American Society of Anaesthesiologists-Physical Status classification in terms of AUROC comparison. CONCLUSION: The development of the CARES surgical risk calculator allows for a simplified yet accurate prediction of both postoperative mortality and need for ICU admission after surgery. PMID- 29574443 TI - Early initiation of post-sternotomy cardiac rehabilitation exercise training (SCAR): study protocol for a randomised controlled trial and economic evaluation. AB - INTRODUCTION: Current guidelines recommend abstinence from supervised cardiac rehabilitation (CR) exercise training for 6 weeks post-sternotomy. This practice is not based on empirical evidence, thus imposing potentially unnecessary activity restrictions. Delayed participation in CR exercise training promotes muscle atrophy, reduces cardiovascular fitness and prolongs recovery. Limited data suggest no detrimental effect of beginning CR exercise training as early as 2 weeks post-surgery, but randomised controlled trials are yet to confirm this. The purpose of this trial is to compare CR exercise training commenced early (2 weeks post-surgery) with current usual care (6 weeks post-surgery) with a view to informing future CR guidelines for patients recovering from sternotomy. METHODS AND ANALYSIS: In this assessor-blind randomised controlled trial, 140 cardiac surgery patients, recovering from sternotomy, will be assigned to 8 weeks of twice-weekly supervised CR exercise training commencing at either 2 weeks (early CR) or 6 weeks (usual care CR) post-surgery. Usual care exercise training will adhere to current UK recommendations. Participants in the early CR group will undertake a highly individualised 2-3 week programme of functional mobility, strength and cardiovascular exercise before progressing to a usual care CR programme. Outcomes will be assessed at baseline (inpatient), pre-CR (2 or 6 weeks post-surgery), post-CR (10 or 14 weeks post-surgery) and 12 months. The primary outcome will be change in 6 min walk distance. Secondary outcomes will include measures of functional fitness, quality of life and cost-effectiveness. ETHICS AND DISSEMINATION: Recruitment commenced on July 2017 and will complete by December 2019. Results will be disseminated via national governing bodies, scientific meetings and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03223558; Pre-results. PMID- 29574444 TI - Opioid use and harms associated with a sustained-release tapentadol formulation: a postmarketing study protocol. AB - INTRODUCTION: It has been argued that tapentadol may pharmacologically have lower abuse potential than other pharmaceutical opioids currently available. However, there has been no comprehensive triangulation of data regarding use and harms associated with this formulation. A sustained-release formulation (SRF) of tapentadol (Palexia) was released in Australia in 2011 and listed for public subsidy in 2013. We summarise here the methods of a postmarketing study which will measure postintroduction: (1) population level availability, (2) extramedical use and diversion, (3) attractiveness for extramedical use and (4) associated harms, of tapentadol compared against other pharmaceutical opioids. METHODS AND ANALYSIS: We evaluated key sources on pharmaceutical use and harms in Australia. This review indicateddata from four sources that disaggregate pharmaceutical opioid formulations and capture tapentadol SRF could be triangulated. These data sources comprised: (1) national pharmaceutical opioid community sales data from 2011 to 2017, (2) national pharmaceutical opioid poisonings reported to Poison Information Centres (PICs) from 2011 to 2017, (3) number of vendors on online marketplaces listing pharmaceutical opioids for sale and (4) data on pharmaceutical opioid extramedical use, attractiveness and harms from interviews with people who regularly inject drugs in Australia. ETHICS AND DISSEMINATION: Ethics approval is not required for use of pharmaceutical sales data. Ethics approval has been obtained for use of national pharmaceutical opioid poisonings reported to PICs (LNR/16/SCHN/44) and for use of online marketplace data and interview data from people who inject drugs (HC12086). Key findings will be published mid-2018 in a peer-reviewed academic journal, and presented at various conferences and professional meetings. PMID- 29574445 TI - Health outcomes of patients with chronic disease managed with a healthcare kiosk in primary care: protocol for a pilot randomised controlled trial. AB - INTRODUCTION: The rising prevalence of chronic disease is leading to an increase in the demand for primary care services and a shortage of primary care physicians globally. Addressing these challenges calls for innovations in the healthcare delivery model with greater use of healthcare technology tools. We previously examined the feasibility of using an automated healthcare kiosk for the management of patients with stable chronic disease in the primary care setting. The aim of this follow-up study is to evaluate the health outcomes of patients with chronic disease who are on kiosk management compared with patients who are on routine management by nurse clinicians. METHODS AND ANALYSIS: The pilot study will be a two-armed randomised controlled trial of 120 patients with well controlled chronic disease on 4-monthly follow-up visits over a 12-month period. Patients with prior diagnoses of hypertension, hyperlipidaemia and/or diabetes will be included in the study and will be randomly assigned to intervention or control groups to receive kiosk or nurse management, respectively. The main primary outcome measure is the overall chronic disease control of the patients. Other primary outcome measures are the blood pressure and low-density lipoprotein cholesterol levels for patients without diabetes, and blood pressure, low-density lipoprotein cholesterol and haemoglobin A1c levels for patients with diabetes. Secondary outcome measures are visit duration, patient satisfaction with the management process, health-related quality of life and the occurrence of any adverse event. Data will be captured longitudinally at baseline, 4 months, 8 months and 12 months, and will be analysed using multiple regression models. ETHICS AND DISSEMINATION: The study has been approved by the Singapore Health Services (SingHealth) Centralised Institutional Review Board (2017/2715). Findings of the study will be submitted for publication in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: NCT03274089; Pre-results.

PMID- 29574448 TI - E-cigarette initiation and associated changes in smoking cessation and reduction: the Population Assessment of Tobacco and Health Study, 2013-2015. AB - BACKGROUND: The role of electronic cigarettes (e-cigarettes) in product transitions has been debated. METHODS: We used nationally representative data from the Population Assessment of Tobacco and Health Study waves 1 (2013-2014) and 2 (2014-2015) to investigate the associations between e-cigarette initiation and cigarette cessation/reduction in the USA. We limited the sample to current cigarette smokers aged 25+ years who were not current e-cigarette users at wave 1. We modelled 30-day cigarette cessation and substantial reduction in cigarette consumption as a function of e-cigarette initiation between surveys using multivariable logistic regression. RESULTS: Between waves 1 and 2, 6.9% of cigarette smokers who were not current e-cigarette users transitioned to former smokers. After adjusting for covariates, cigarette smokers who initiated e cigarette use between waves and reported they used e-cigarettes daily at wave 2 had 7.88 (95% CI 4.45 to 13.95) times the odds of 30-day cigarette cessation compared with non-users of e-cigarettes at wave 2. Cigarette smokers who began using e-cigarettes every day and did not achieve cessation had 5.70 (95% CI 3.47 to 9.35) times the odds of reducing their average daily cigarette use by at least 50% between waves 1 and 2 compared with e-cigarette non-users. CONCLUSIONS: Daily e-cigarette initiators were more likely to have quit smoking cigarettes or reduced use compared with non-users. However, less frequent e-cigarette use was not associated with cigarette cessation/reduction. These results suggest incorporating frequency of e-cigarette use is important for developing a more thorough understanding of the association between e-cigarette use and cigarette cessation. PMID- 29574449 TI - Price, tax and tobacco product substitution in Zambia. AB - BACKGROUND: In Zambia, the number of cigarette users is growing, and the lack of strong tax policies is likely an important cause. When adjusted for inflation, levels of tobacco tax have not changed since 2007. Moreover, roll-your-own (RYO) tobacco, a less-costly alternative to factory-made (FM) cigarettes, is highly prevalent. DATA AND METHODS: We modelled the probability of FM and RYO cigarette smoking using individual-level data obtained from the 2012 and 2014 waves of the International Tobacco Control (ITC) Zambia Survey. We used two estimation methods: the standard estimation method involving separate random effects probit models and a method involving a system of equations (incorporating bivariate seemingly unrelated random effects probit) to estimate price elasticities of FM and RYO cigarettes and their cross-price elasticities. RESULTS: The estimated price elasticities of smoking prevalence are -0.20 and -0.03 for FM and RYO cigarettes, respectively. FM and RYO are substitutes; that is, when the price of one of the products goes up, some smokers switch to the other product. The effects are stronger for substitution from FM to RYO than vice versa. CONCLUSIONS: This study affirms that increasing cigarette tax with corresponding price increases could significantly reduce cigarette use in Zambia. Furthermore, reducing between-product price differences would reduce substitution from FM to RYO. Since RYO use is associated with lower socioeconomic status, efforts to decrease RYO use, including through tax/price approaches and cessation assistance, would decrease health inequalities in Zambian society and reduce the negative economic consequences of tobacco use experienced by the poor.

PMID- 29574446 TI - Comparison of incidence, rate and length of all-cause hospital admissions between adults with normoglycaemia, impaired fasting glucose and diabetes: a retrospective cohort study in Geelong, Australia. AB - OBJECTIVE: To determine whether adults with normoglycaemia, impaired fasting glucose (IFG) and diabetes differed according to the incidence, rate, length and primary reasons for hospital admission. DESIGN: Retrospective cohort study. SETTING: Barwon Statistical Division, Geelong, Australia. PARTICIPANTS: Cohort included 971 men and 924 women, aged 20+ years, participating in the Geelong Osteoporosis Study. Glycaemic status was assessed at cohort entry using fasting plasma glucose, use of antihyperglycaemic medication and/or self-report. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome measure was any admission to the major tertiary public hospital in the study region over the follow-up period. Secondary outcome measures were admission rate and length (days). RESULTS: Over a median follow-up of 7.4 years (IQR 5.3-9.6), participants with diabetes, compared with those with normoglycaemia, were two times as likely to be hospitalised (OR 2.07, 95% CI 1.42 to 3.02), had a higher admission rate (incidence rate ratio 1.61, 95% CI 1.17 to 2.23) and longer hospital stay (third quartile difference 7.7, 95% CI 1.3 to 14.1 and ninth decile difference 16.2, 95% CI 4.2 to 28.3). IFG group was similar to normoglycaemia for the incidence, rate and length of admission. Cardiovascular disease-related diagnoses were the most common primary reasons for hospitalisation across all glycaemic categories. CONCLUSIONS: Our results show increased incidence, rate and length of all-cause hospital admission in adults with diabetes as compared with normoglycaemia; however, we did not detect any associations for IFG. Interventions should focus on preventing IFG-to diabetes progression and reducing cardiovascular risk in IFG and diabetes.

PMID- 29574451 TI - Patient demographic and surgical characteristics in anterior cruciate ligament reconstruction: a description of registries from six countries. AB - OBJECTIVE: Findings from individual anterior cruciate ligament reconstruction (ACLR) registry studies are impactful, but how various registries from different countries compare with different patient populations and surgical techniques has not been described. We sought to describe six ACLR registry cohorts to understand variation across countries. METHODS: Five European registries and one US registry participated. For each registry, all primary ACLR registered between registry establishment through 31December 2014 were identified. Descriptive statistics included frequencies, proportions, medians and IQRs. Revision incidence rates following primary ACLR were computed. RESULTS: 101 125 ACLR were included: 21 820 in Denmark, 300 in Luxembourg, 17 556 in Norway, 30 422 in Sweden, 2972 in the UK and 28 055 in the US. In all six cohorts, males (range: 56.8%-72.4%) and soccer injuries (range: 14.1%-42.3%) were most common. European countries mostly used autografts (range: 93.7%-99.7%); allograft was most common in the US (39.9%). Interference screw was the most frequent femoral fixation in Luxembourg and the US (84.8% and 42.9%), and suspensory fixation was more frequent in the other countries (range: 43.9%-75.5%). Interference was the most frequent tibial fixation type in all six cohorts (range: 64.8%-98.2%). Three-year cumulative revision probabilities ranged from 2.8% to 3.7%. CONCLUSIONS: Similarities in patient demographics and injury activity were observed between all cohorts of ACLR. However, graft and fixation choices differed. Revision rates were low. This work, including >100 000 ACLR, is the most comprehensive international description of contemporary practice to date. PMID- 29574453 TI - Infographic.

PMID- 29574456 TI - Modeling Short QT Syndrome Using Human-Induced Pluripotent Stem Cell-Derived Cardiomyocytes. AB - BACKGROUND: Short QT syndrome (SQTS), a disorder associated with characteristic ECG QT-segment abbreviation, predisposes affected patients to sudden cardiac death. Despite some progress in assessing the organ-level pathophysiology and genetic changes of the disorder, the understanding of the human cellular phenotype and discovering of an optimal therapy has lagged because of a lack of appropriate human cellular models of the disorder. The objective of this study was to establish a cellular model of SQTS using human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). METHODS AND RESULTS: This study recruited 1 patient with short QT syndrome type 1 carrying a mutation (N588K) in KCNH2 as well as 2 healthy control subjects. We generated hiPSCs from their skin fibroblasts, and differentiated hiPSCs into cardiomyocytes (hiPSC-CMs) for physiological and pharmacological studies. The hiPSC-CMs from the patient showed increased rapidly activating delayed rectifier potassium channel current (IKr) density and shortened action potential duration compared with healthy control hiPSC-CMs. Furthermore, they demonstrated abnormal calcium transients and rhythmic activities. Carbachol increased the arrhythmic events in SQTS but not in control cells. Gene and protein expression profiling showed increased KCNH2 expression in SQTS cells. Quinidine but not sotalol or metoprolol prolonged the action potential duration and abolished arrhythmic activity induced by carbachol. CONCLUSIONS: Patient-specific hiPSC-CMs are able to recapitulate single-cell phenotype features of SQTS and provide novel opportunities to further elucidate the cellular disease mechanism and test drug effects. PMID- 29574457 TI - Characteristics of Phrenic Nerve Injury During Pulmonary Vein Isolation Using a 28-mm Second-Generation Cryoballoon and Short Freeze Strategy. AB - BACKGROUND: The reported incidence of phrenic nerve injury (PNI) varies owing to different definitions, balloon generations, balloon size, freezing regimen, and protective maneuvers. We evaluated the incidence, predictors, and outcome of PNI during cryoballoon pulmonary vein isolation in a large population. METHODS AND RESULTS: Five hundred fifty atrial fibrillation patients underwent pulmonary vein isolation using one 28-mm second-generation cryoballoon and single 3-minute freeze strategy under diaphragmatic compound motor action potential (CMAP) monitoring. A total of 34 (6.2%) patients experienced PNI during the right superior and inferior pulmonary vein ablation in 30 and 4 patients, respectively. Applications were interrupted using double-stop techniques after 136 [104-158] second applications, and a pulmonary vein isolation was already achieved in all but one case. The baseline CMAP amplitude and timing of deflation (CMAPdef) were 0.75+/-0.30 and 0.17+/-0.17 mV, respectively. Persistent atrial fibrillation, larger right superior pulmonary vein ostia, and deeper balloon positions were associated with higher incidences of PNI. The CMAPdef predicted a PNI recovery delay, and the best cutoff value for predicting PNI recovery by the next day was 0.20 mV (sensitivity 57.1%, specificity 100%). Among 6 patients undergoing second procedures 8.5 (6.7-15.0) months later, the right superior pulmonary vein was durable in 3 with >120 second applications. Despite active balloon deflation, no significant pulmonary vein stenosis was observed in 15 right superior pulmonary veins evaluated 6 (5-9) months later. No patients had symptoms, and the PNI recovered 1 day and 1 month postprocedure in 21 and 4 patients, respectively. CONCLUSIONS: PNI resulting from cryoballoon ablation was reversible. The double stop technique is safe, and immediate active deflation following a CMAP decrease appears to be essential for faster PNI recovery. PMID- 29574458 TI - Coffee Consumption and Coronary Artery Calcium Score: Cross-Sectional Results of ELSA-Brasil (Brazilian Longitudinal Study of Adult Health). AB - BACKGROUND: Available evidence for the relationship between coffee intake and subclinical atherosclerosis is limited and inconsistent. This study aimed to evaluate the association between coffee consumption and coronary artery calcium (CAC) in ELSA-Brasil (Brazilian Longitudinal Study of Adult Health). METHODS AND RESULTS: This cross-sectional study is based on baseline data from participants of the ELSA-Brasil cohort. Only participants living in Sao Paulo, Brazil, who underwent a CAC measurement (n=4426) were included. Coffee consumption was collected using a food frequency questionnaire. CAC was detected with computed tomography and expressed as Agatston units. CAC was further categorized as an Agatson score >=100 (CAC >=100). In multiple logistic regression analysis considering intake of coffee and smoking status interaction, significant inverse associations were observed between coffee consumption (>3 cups/d) and CAC>=100 (odds ratio [OR]: 0.85 [95% confidence interval, 0.58-1.24] for <=1 cup/d; OR: 0.73 [95% confidence interval, 0.51-1.05] for 1-3 cups/d; OR: 0.33 [95% confidence interval, 0.17-0.65] for >3 cups/d). Moreover, there was a statistically significant interaction effect for coffee consumption and smoking status (P=0.028 for interaction). After stratification by smoking status, the analysis revealed a lower OR of coronary calcification in never smokers drinking >3 cups/d (OR: 0.37 [95% confidence interval, 0.15-0.91]), whereas among current and former smokers, the intake of coffee was not significantly associated with coronary calcification. CONCLUSIONS: Habitual consumption of >3 cups/d of coffee decreased odds of subclinical atherosclerosis among never smokers. The consumption of coffee could exert a potential beneficial effect against coronary calcification, particularly in nonsmokers. PMID- 29574459 TI - Relation of Insulin Resistance to Longitudinal Changes in Left Ventricular Structure and Function in a General Population. AB - BACKGROUND: Population data on the longitudinal changes of left ventricular (LV) structure and function in relation to insulin resistance are sparse. Therefore, we assessed in a general population whether hyperinsulinemia predicts longitudinal changes in LV and arterial characteristics. METHODS AND RESULTS: In 627 participants (mean age 50.7 years, 51.4% women), we assessed echocardiographic indexes of LV structure and function and carotid-femoral pulse wave velocity by applanation tonometry at baseline and after 4.7 years. We regressed longitudinal changes in these indexes on baseline insulin and its change during follow-up, and reported standardized effect sizes as a percentage of the SD of LV changes associated with a doubling of insulin. After adjustment, higher baseline insulin predicted a greater temporal increase in LV mass index (effect size: +15.1%) and E/e' ratio (+22.1%), and a greater decrease in e' peak and longitudinal strain (-11.2% to -17.1%). A greater increase in insulin during follow-up related to a greater increase in LV mass index (+10.7%) and decline in ejection fraction and longitudinal strain (-11.4% to -15.7%). Participants who became or remained insulin resistant during follow-up experienced worse changes in longitudinal strain, E/e', and LV mass index as compared with participants who did not develop or had improved insulin resistance over time (P<=0.033). Moreover, multivariable-adjusted increase in pulse wave velocity was higher in participants with diabetes mellitus than in participants without diabetes mellitus (+1.46 m/s versus +0.71 m/s; P=0.039). CONCLUSIONS: Hyperinsulinemia at baseline and during follow-up predicted worsening of LV function and remodeling over time. Our findings underline the importance of management of insulin resistance. PMID- 29574460 TI - The Unexpected Role of Calcium-Activated Potassium Channels: Limitation of NO Induced Arterial Relaxation. AB - BACKGROUND: Multiple studies have shown that an NO-induced activation of vascular smooth muscle BK channels contributes to the NO-evoked dilation in many blood vessels. In vivo, NO is released continuously. NO attenuates vessel constrictions and, therefore, exerts an anticontractile effect. It is unknown whether the anticontractile effect of continuously present NO is mediated by BK channels. METHODS AND RESULTS: This study tested the hypothesis that BK channels mediate the vasodilatory effect of continuously present NO. Experiments were performed on rat and mouse tail and rat saphenous arteries using isometric myography and FURA 2 fluorimetry. Continuously present NO donors, as well as endogenous NO, attenuated methoxamine-induced vasoconstrictions. This effect was augmented in the presence of the BK channel blocker iberiotoxin. Moreover, the contractile effect of iberiotoxin was reduced in the presence of NO donors. The effect of the NO donor sodium nitroprusside was abolished by an NO scavenger and by a guanylyl cyclase inhibitor. In addition, the effect of sodium nitroprusside was reduced considerably by a protein kinase G inhibitor, but was not altered by inhibition of H2S generation. Sodium nitroprusside attenuated the intracellular calcium concentration response to methoxamine. Furthermore, sodium nitroprusside strongly reduced methoxamine-induced calcium influx, which depends entirely on L-type calcium channels. It did not affect methoxamine-induced calcium release. CONCLUSIONS: In summary, this study demonstrates the following: (1) continuously present NO evokes a strong anticontractile effect on rat and mouse arteries; (2) the iberiotoxin-induced augmentation of the effect of NO is associated with an NO induced reduction of the effect of iberiotoxin; and (3) NO evoked a reduction of calcium influx via L-type calcium channels.

AB - BACKGROUND: The purpose of this study was to examine associations between several types of police-recorded crime (violent, nonviolent, and homicide) and cardiometabolic health (obesity and elevated blood pressure [BP]), and to determine if associations were modified by age and sex. METHODS AND RESULTS: We analyzed cross-sectional data (N=14 799 patients) from 3 primary care clinics at an academic medical center in Chicago, IL. Patient-level health data were obtained from the electronic health record (June 1, 2014-May 31, 2015), including body mass index and BP, and linked to the City of Chicago Police Data Portal. Geocoded crime counts were aggregated to census tract and calculated as the annual crime rate per 1000 population. Generalized linear mixed models were used to assess obesity and BP status as a function of crime rate quartile, controlling for patient, clinic, and neighborhood characteristics. Median violent crime rates in each quartile ranged from 15 to 84 per 1000 population. Median age was 56 years (interquartile range, 38-72 years); 42% of patients were obese and 33% had elevated BP. Compared with patients living in the lowest quartile, patients living in the highest quartile for violent crime had 53% higher adjusted odds of obesity (95% confidence interval, 1.15-2.03) and 25% higher adjusted odds of elevated BP (95% confidence interval, 1.01-1.56). In subanalyses examining homicide, a relatively rare event, exposure was not associated with obesity and was inconsistently associated with elevated BP. CONCLUSIONS: In a densely populated, high-poverty region in Chicago, recurrent exposure to high rates of violent crime was consistently associated with obesity and elevated BP, but rare exposure to homicide was not.

AB - BACKGROUND: Vasovagal syncope (VVS) is characterized by hypotension and bradycardia followed by lowering of cerebral blood flow. Remote limb ischemic preconditioning (RIPC) is well documented to provide cardio- and neuroprotection as well as to improve cerebral blood flow. We hypothesized that RIPC will provide protection against VVS-induced hypotension, bradycardia, and cerebral hypoperfusion. Second, because endothelial nitric oxide synthase has been reported as a mediator of cerebral blood flow control, we hypothesized that the mechanism by which RIPC primes the vasculature against VVS is via the alpha1 adrenoceptor-protein kinase Cepsilon-endothelial nitric oxide synthase pathway. METHODS AND RESULTS: We utilized sinusoidal galvanic vestibular stimulation in rats as a model of VVS. RIPC attenuated the lowerings of mean arterial pressure, heart rate, and cerebral blood flow caused by sinusoidal galvanic vestibular stimulation, as well as improving behavior during, and recovery after, stimulation. RIPC induced elevated serum norepinephrine, increased expression of brain alpha1-adrenoceptors, and reduced brain expression of norepinephrine transporter 1. Antagonizing adrenoceptors and norepinephrine transporter 1 prevented RIPC protection of cerebral perfusion during sinusoidal galvanic vestibular stimulation. CONCLUSIONS: Taken together, this study indicates that RIPC may be a potential therapy that can prevent VVS pathophysiology, decrease syncopal episodes, and reduce the injuries associated with syncopal falls. Furthermore, the alpha1-adrenoceptor-protein kinase Cepsilon-endothelial nitric oxide synthase pathway may be a therapeutic target for regulating changes in cerebral blood flow.

PMID- 29574464 TI - Weekly variations in feelings of trust predict incident STI within a prospective cohort of adolescent women from a US city. AB - OBJECTIVES: Feelings of intimacy, perceptions of partner concurrency (PPC) and perceptions of risk for an STD (PRSTD) are meaningful and dynamic attributes of adolescent sexual relationships. Our objective was to examine whether variations in these STI-associated feelings and perceptions predicted incident Chlamydia trachomatis and/or Neisseriagonorrhoeae infection within a prospective cohort of urban adolescent women. METHODS: A cohort of clinic-recruited women aged 16-19 completed daily surveys on feelings and risk perceptions about each current sex partner on a smartphone continuously for up to 18 months. Urine was tested for C. trachomatis and N. gonorrhoeae every 3 months. Daily responses were averaged across the week. As overall means for trust, closeness and commitment were high, data were coded to indicate any decrease in feelings from the previous week. PRSTD and PPC were reverse coded to indicate any increase from the previous week. An index was created to examine the cumulative effect of variation in these feelings and perceptions. Generalised linear models were used to account for correlation among repeated measures within relationships. RESULTS: For each week that there was a decrease in trust, there was a 45% increase in the risk of being infected with an STI at follow-up (relative risk (RR) 1.45, 95% CI 1.18 to 1.78, P=0.004). Neither a decrease in closeness or commitment, nor an increase in PRSTD or PPC was associated with an STI outcome. Cumulatively, the index measure indicated that a change in an additional feeling or perception over the week increased the odds of an STI by 14% (RR 1.14, 95% CI 1.02 to 1.29, P=0.026). CONCLUSIONS: A decrease in feelings of trust towards a main partner may be a more sensitive indicator of STI risk than PRSTD, PPC or commitment. The next generation of behavioural interventions for youth will need strategies to address feelings of intimacy within adolescent romantic relationships. PMID- 29574465 TI - Individual-level characteristics associated with oral HIV test acceptability among Peruvian men who have sex with men and transgender women: a cross-sectional study. AB - OBJECTIVES: Peruvian men who have sex with men (MSM) and transgender women (TGW) are highly vulnerable to HIV infection (HIV), but stigma, access issues and fear of venipuncture hamper testing. The oral HIV test-which uses oral fluids and provides results in 20 minutes-could reduce these barriers. The objective of this study was to determine the acceptability of the oral HIV test and the individual level factors associated with its acceptability among MSM and TGW. METHODS: We conducted a cross-sectional secondary analysis among Peruvian MSM and TGW attending a community-based health centre between February 2012 and February 2013 to determine the individual-level factors associated with oral HIV test acceptability. RESULTS: Of 334 participants, 88% were MSM and 12% TGW. Overall, 85% of participants indicated their acceptability of the oral HIV test. Acceptability was higher in MSM than TGW (85.7% vs 80.0%) but this difference was not significant. Factors associated with acceptability in MSM were: tertiary or higher education (prevalence ratio (PR)=1.18, 95% CI 1.06 to 1.32 and PR=1.16, 95% CI 1.03 to 1.30, respectively); sex with drug use (PR=1.19, 95% CI 1.05 to 1.36); believing that HIV is transmitted by saliva (PR=1.20, 95% CI 1.08 to 1.33); and potential use of the oral test at home (PR=1.56, 95% CI 1.32 to 1.85). The only factor associated with lower acceptability was having had first anal intercourse between 14 and 19 years of age (PR=0.89, 95% CI 0.80 to 0.98). CONCLUSIONS: We identified the individual factors associated with oral HIV test acceptability among Peruvian MSM and TGW. Expanded use of the oral HIV test to increase testing rates among Peruvian MSM and TGW is recommended. TRIAL REGISTRATION NUMBER: NCT01387412, post-results. PMID- 29574466 TI - Clinical Significance of Ubiquitin Specific Protease 7 (USP7) in Predicting Prognosis of Hepatocellular Carcinoma and its Functional Mechanisms. AB - BACKGROUND Hepatocellular carcinoma (HCC) accounts for one of the most prevalent cancer types in the world. The ubiquitin specific protease 7 (USP7), a kind of deubiquitylating enzyme, has been reported to play multifaceted roles in different tumor types. The aim of this study was to investigate the expression and function of USP7 in HCC. MATERIAL AND METHODS Immunohistochemical staining and quantitative PCR were performed to explore the expression of USP7 in both HCC tissues and adjacent normal liver tissues. Chi-square test, univariate analysis, and multivariate analysis were conducted to statistically evaluate the clinical significance of USP7 in HCC. Proliferation, migration, and invasion capacities of HCC cells were assessed after overexpressing or silencing USP7. RESULTS Both the RNA and protein levels of USP7 were upregulated in HCC tissues compared to normal liver tissues. High expression of USP7 was correlated with advanced tumor stage and poor overall survival. Moreover, USP7 was identified as a novel independent prognostic factor for HCC patients. Cellular studies showed that USP7 could enhance the proliferation, migration, and invasion capacities of HCC cells, thereby promoting tumor progression. CONCLUSIONS High expression of USP7 is frequent in HCC tissues, which promotes tumor proliferation and invasion, and is correlated with a poor overall survival. Targeting USP7 may be a novel direction for the drug development of HCC therapy. PMID- 29574467 TI - Correlation Between Pigment Epithelium-Derived Factor (PEDF) level and Degree of Coronary Angiography and Severity of Coronary Artery Disease in a Chinese Population. AB - BACKGROUND The role of pigment epithelium-derived factor (PEDF) in protection of coronary artery disease (CAD) remains controversial. The aim of this study was to reassess the value of PEDF in predicting the severity and prognosis of newly diagnosed stable CAD in a Chinese population. MATERIAL AND METHODS Plasma PEDF levels were measured in 259 stable CAD patients undergoing coronary angiography and 116 age- and sex-matched healthy controls. The severity of coronary atherosclerosis was assessed using Gensini score. RESULTS PEDF levels were significantly lower in CAD patients than in healthy subjects (5.856+/-0.790 vs. 6.658+/-1.070 MUg/ml, respectively, p<0.01). Stepwise regression analysis showed a negative correlation between PEDF levels and severity of CAD as quantified by Gensini score value (beta=-0.626, p<0.01). CONCLUSIONS Our study showed that plasma PEDF levels were significantly lower in CAD patients than in controls, and the plasma PEDF levels may be used as a potential predicator for coronary severity. PMID- 29574468 TI - Phenotypic Variability of c.436delC DCAF17 Gene Mutation in Woodhouse-Sakati Syndrome. AB - BACKGROUND Woodhouse-Sakati syndrome (WSS) is a rare autosomal recessive genetic condition that was first described in 1983. Since its original description, approximately 50 cases have been reported with various clinical signs and symptoms. Characteristics include progressive neurologic deterioration with extrapyramidal involvement and polyendocrinopathy most notable for hypogonadism starting in early adolescence. Clinical presentation is variable, and a subset of patients may have additional features, such as premature aging, alopecia, distinctive facial features, cognitive impairment, or deafness. CASE REPORT We illustrate the phenotypic variability of 5 patients with WSS due to the previously reported homozygous single nucleotide deletion c.436delC in the DCAF17 gene, identified in 2008. Despite identical genetic alteration, our 5 patients had various clinical features among them and compared with previously reported cases with the same pathogenic mutation. CONCLUSIONS The phenotypic variability of WSS due to c.436delC founder mutation may have a wider range than previously recognized. PMID- 29574469 TI - Adverse effect of the disturbances of glycemia and insulimemia on model PC12 cells - preliminary report. AB - BACKGROUND: One of the most important worldwide health problems of the 21st century is an increasing incidence of diabetes and insulin resistance. Morover, it is indicated that both these disturbances are connected with an increased incidence of Alzheimer's Disease. The literature data indicate that not only disturbed glucose concentration, especially hyperglycemia, is a crucial factor of the development of dementia but those data also emphasize that hyperphysiological concentrations of insulin and insulin resistance of brain tissue is an increasingly significant factor. The aim of this study was to evaluate the influence of glucose and insulin concentration reached in human carbohydrate metabolism disorders such as i.e. impaired fasting glucose, impaired glucose tolerance and diabetes state as well as averageand high degree hyperinsulinemia, on the survival of PC12 cell line. MATERIAL AND METHODS: Because of the close association indicated between diabetes and neurodegenerative diseases, in the experiment we used PC12 cell line derived from a transplantable rat pheochromocytoma, commonly used as an neurotoxicity and neuroprotection model. These cells were incubated in RPMI 1640 with addition of fetal bovine serum, horse serum, antibiotics and appropriate concentrations of glucose(from 84 to 240 mg/mL) and insulin(0.5 to 7 mg/mL) at 37 degrees C in a humidified atmosphere containing 5% of CO2for 24 h and 48 h. Cell viability was expressed as a percentage of survival (PS [%]) against the negative control after MTT assay execution. RESULTS: The highest mortality was demonstrated for PC12 lines incubated for 24 h with the glucose level reflecting the condition of diabetes mellitus (DM), while after an incubation period of 48 h, the highest mortality was demonstrated for the incubation with insulin concentration corresponding to high levels of hyperinsulinemia (HH). Conclutions. The results suggest the greater susceptibility of PC12 cells to extended hyperinsulinaemia incubation than hyperglycemia,which indicates the increasing importance of insulin disorders in the induction of cell death.The results demonstrated in our experiment are particularly important for the development of a study model for testing the substances with hypoglycaemic, hypoinsulinemic and neuroprotective action. PMID- 29574470 TI - Epidemiological aspects of obesity and systemic hypertension amongschool children of Western Ukraine. AB - INTRODUCTION: Systemic hypertension (SH) is a major long-term health condition and is the leading cause of premature death among adults throughout the world, including developed, developing, and lesser developed countries.In recent years there has been a progressive increase in SH among children and adolescents. Epidemiological studies demonstrated an overall increase in the prevalence of hypertension. SH is rarely recorded isolated and is often combined with obesity or the metabolic syndrome. AIM OF THE STUDY: The aim of our research was to study the prevalence of overweight, obesity, and systemic hypertension in Ukrainian school children aged 10-16 years. MATERIAL AND METHODS: 540 pupils of two secondary schools in the city of Ternopil, aged 10-16 years, were involved. Blood pressure was measured under standard conditions using the standard technique. To assess the physical development of each child, indicators of body weight, height, waist circumferences and body mass index were compared with percentile tables. RESULTS: The study has demonstrated that the prevalence of overweight is 11.1% and obesity 4.8% among pupils of Ternopil. The elevated blood pressure was found in 50 % of overweight or obese pupils. SH was found in 13.3% of children (11.8% of girls and 15.1% of boys), where pre-hypertension (p<0,01) and SH 1st (p<0,01) stages were observed twice as often in boys than in girls, and normal BP was recorded less frequently (p<0,01). CONCLUSIONS: The boys are three times more often obese than girls and 1.4 times more often overweight. The blood pressure is directly correlated with increased BMI, waist and hip circumference in the examined children. The abdominal obesity is a predictor of hypertension in adolescents. The result of the present study has demonstrated the real epidemiology of obesity and systemic hypertension in children and adolescents, and should motivate family doctors and paediatricians to prevent this pathology in Ukraine. PMID- 29574471 TI - Assessing the knowledge of the consequences of uncontrolled diabetesin pregnancy and its effects on fetal development, among femaleadolescents with type 1 diabetes. AB - INTRODUCTION: Two forms of diabetes can be distinguished during pregnancy: gestational diabetes and pregestational diabetes, which exists prior to pregnancy. In young women, the most common form of pregestational diabetes is type 1 diabetes (T1D). Regarding the decreasing age of sexual initiation and health risks for the mother and child related to hyperglycemia, it is essential that adolescents with T1D possess proper knowledge of pregnancy planning and diabetes management in case of pregnancy. Preconception counseling in adolescent patients with T1D remains a challenge for the whole therapeutic team. AIM OF THE STUDY: Assessing the awareness of consequences of uncontrolled diabetes on the course of pregnancy and fetal development among patients with T1D. MATERIAL AND METHODS: The study was carried out in the group of 70 patients with T1D, aaged 15 18 years. The survey was consisted of 25 questions regarding health status, lifestyle, the knowledge of self-management of diabetes and the impact of diabetes on pregnancy and fetal development. Respondents were asked to indicate the sources of information from which they had gianed knowledge about the aforesaid issues. The data obtained were statistically analyzed. RESULTS: 20% (n=14) of respondents declared sexual activity. In the group of sexually active patients, in 50% (n=7) last HbA1c level, reported by subjects, was between 7.5 9%, and in 21.4% (n=3) >9%. The patients were aware of the consequences of uncontrolled diabetes on fetal development, however their knowledge was unsatisfactory. Surveyed adolescents indicated metabolic disorders (61.4 %, n=43), central nervous system malformations (55.7%, n=39) and heart defects (47.1%, n=33) as the most frequent complications. The respondents gathered knowledge mainly from a diabetologist (40%, n=28) and the Internet (40%, n=28). The majority of patients stated that preconception care should be provided by a diabetologist (88.6%, n=62) or a gynecologist (70%, n=49). CONCLUSION: In spite of continuous diabetes care, adolescents with T1D do not possess sufficient knowledge regarding the consequences of hyperglycemia during pregnancy. This study has emphasized the need for including reproductive health issues in diabetes education addressed to adolescent patients. PMID- 29574472 TI - [Effects of oncological therapy on bone disorders]. AB - Due to increasing incidence of cancer disease and the searching for new, aggressive methods of therapy, more attention is focusing on applied treatment consequences. The specificity of oncological drugs allows to destroy cancer cells, simultaneously destroying and disrupting the functioning of healthy tissues. Side effects concern infertility, urolotoxicity, nephrotoxicity, neurotoxicity or bone marrow suppression. Chemotherapy can also be affected on physiological function of movement system and the skeleton construction. Mineral status disorders and skeletal changes lead to secondary forms of osteopenia and osteoporosis and refer oncological patients of any age. The main cause of these conditions is an imbalance between osteoclast and osteoblast activity, occurring as a result of drug interactions, parathyroid hormone-like proteins or interleukins. In addition to the direct effect on bone tissue, disorders in its construction and metabolism are also manifested as a consequence of hypogonadism. The sexual hormones at normal level can inhibit process of bone destruction, increase parathormone level, stimulate active vitamin D3 formation and intestinal calcium absorption. The deficiency of estrogens and androgens indirectly leads to disorder of bone metabolism and homeostasis. Symptoms such as musculoskeletal pain and fractures appear in the late stage of degeneration. Moreover, the appropriate selection of therapy and dosage, compatible with the patient's age and condition are crucial for treatment. Early bone loss should be prevented by supplementing with calcium, vitamin D3, hormone replacement therapy or bisphosphonates. The physical activity and proper diet are important as well. The aim of the study was to characterize the most common oncological treatment regimens, considering the long-term side effect of applied therapy and its influence on the skeletal mineralization and trace element profile. Based on the mechanism of drug action, the disorders observed after pharmacotherapy were described. The processes leading to bone's composition changes were discussed and prevention of their occurrence were estimated. PMID- 29574473 TI - Metabolic disorders in polycystic ovary syndrome. AB - Polycystic ovary syndrome (PCOS) is a complex disease. Depending on the used criteria the prevalence of PCOS ranges from 6 to 20%. It is necessary to exclude diseases leading to androgen excess. The participation of genetic and environmental factors is considered in the etiology of PCOS development. The highest rate of incidence of PCOS is assessed in girls who were born SGA and developed premature adrenarche later in life.The free androgen index (FAI) is concerned as the most sensitive marker of hyperandrogenaemia in PCOS although insulin resistance, anti-Mullerian hormone (AMH),and deficiency of vitamin D may intensify metabolic disturbances. The ultrasound criteria used in adolescent patients prefer the estimation of the ovarian volume or the ratio of ovarian stroma to total ovary, rather than the number of ovarian follicles. PCOS is connected with different metabolic disorders. Post-binding defect in signal transduction is responsible for insulin resistance. This defect results from an impaired activity of the kinase receptor. Moreover, the adipose tissue of PCOS women differs substantially from the tissue of the others according to morphology and function. The adipocytes produce lower amounts of adiponectin, which is an insulin-sensitizing agent. Dyspidemia with high triglycerides and low high density lipoprotein cholesterol concentrations is frequently noticed. Cardio metabolic risk factors, insulin resistance, and endothelial dysfunction accompany PCOS from the very beginning. Oxidative stress plays a role as a link among systemic inflammation and dysfunction of endothelial cells and abnormal thecal cell action. The treatment efforts in PCOS depend on the patient's main problems. Modification of diet and lifestyle is the most important recommended advice to each woman independent of age and weight. PMID- 29574474 TI - Thyroid hormone resistance syndrome - own experiences. AB - Thyroid hormone resistance syndrome, also known as Refetoff syndrome, is a rare disease associated with decreased reaction of body tissues to thyroid hormones (TH). Patients with Refetoff syndrome tend to have elevated free TH concentrations and normal or inadequately elevated TSH (caused by thyrotropic cells in the pituitary gland insensitivity to TH). The cause of the disease is the mutation in TR-beta receptor gene. Depending on the clinical presentation generalised and pituitary resistance to TH are described. The syndrome is often misdiagnosed as hyperthyroidism and unnecessarily treated with anti-thyroid drugs. Some patients receive l-thyroxine treatment for apparent hypothyroidism. In this report, three patients are presented with a long history in our Clinic and Outpatient Clinic. PMID- 29574475 TI - Is growth without IGF1 possible? A case report. AB - According to the growth hormone - insulin-like growth factor 1 axis (GH/IGF1 axis) theory, the actions of GH on promoting growth are mediated by IGF1. In the blood, IGF1, insulin-like growth factor 1 binding protein 3 (IGFBP3) and acid labile subunit (ALS) form ternary complexes, hence the accumulation of IGF1. We report a case of 10-year-old male with short stature due to GH deficiency diagnosed with hypopituitarism. Therapy with recombinant human GH (rhGH) was initiated at 11 years and 4 months. After twenty three months on treatment clinical effects were as follows: increase in the patient's height by 19.2 cm (initial height 12.4 cm vs. 140.6 cm; hSDS -4.35 vs. -2.7; predicted adult height 176 cm vs. 182 cm, respectively). Despite good clinical response to the therapy, serum levels of IGF1 and IGFBP3 remained diminished: IGF1 - 28 ng/ml initially, vs. 23 ng/ml 19 months on therapy and IGFBP3 - 1116 ng/ml initially, vs. 1888 ng/ml after 11 months on therapy. We attempt to justify this phenomenon by reconsidering the IGF1-independent GH actions, assessing the endocrine role of hepatic IGF1 in comparison to the autocrine/paracrine role of its bone tissue fraction, and evaluating the functions of ALS. The exact explanation for the positive response to rhGH treatment without the expected increase in IGF1 in our patient remains unknown. Serum levels of IGF1 and IGFBP3 seem not always to be reliable markers of the response to rhGH treatment in GH-deficient patients. PMID- 29574476 TI - Exposure to traffic noise and air pollution and risk for febrile seizure: a cohort study. AB - Objectives Exposure to traffic noise and air pollution is suspected to increase susceptibility to viral infections - the main triggering factor for febrile seizures. No studies have examined these two exposures in relation to febrile seizures. We aimed to investigate whether exposure to road traffic noise and air pollution are associated with risk of febrile seizures in childhood. Methods From our study base of 51 465 singletons from a national birth cohort, we identified 2175 cases with febrile seizures using a nationwide registry. Residential address history from conception to six years of age were found in national registers, and road traffic noise (L den) and air pollution (NO 2) were modeled for all addresses. Analyses were done using Cox proportional hazard model with adjustment for potential confounders, including mutual exposure adjustment. Results An interquartile range (IQR) increase in childhood exposure to road traffic noise and air pollution was associated with an 11% [incidence rate ratio (IRR) 1.11, 95% confidence interval (CI) 1.04-1.19) and 5% (IRR 1.05, 95% CI 1.02-1.07) higher risk for febrile seizures, respectively, after adjustment for potential confounders. Weaker tendencies were seen for pregnancy exposure. In models with mutual exposure adjustment, the estimates were slightly lower, with IRR of 1.08 (95% CI 1.00-1.16) and 1.03 (95% CI 0.99-1.06) per IQR increase in childhood exposure to road traffic noise and air pollution, respectively. Conclusions This study suggests that residential exposure to road traffic noise and air pollution is associated with higher risk for febrile seizures. PMID- 29574477 TI - Is perception of safety climate a relevant predictor for occupational accidents? Prospective cohort study among blue-collar workers. AB - Objectives The capability of safety climate to predict accidents has been the target of widespread debate in occupational health and safety research. The objective of this prospective cohort study was to employ a shortened five-item safety climate survey to investigate whether safety climate reports in 2012 are predictive for accidents reported within the last 12 months in 2014. Methods In both 2012 and 2014, 3864 blue-collar workers answered the Danish Working Environment and Health Cohort Study. Logistic regression was used to study the association [odds ratio (OR)] of reporting a work-related accident (yes/no) with more than one day of sickness absence (outcome) within the last 12 months in 2014 with the number of safety climate problems (predictor). The analyses were cumulatively adjusted for age, gender (model 1), socioeconomic class, occupational group, lifestyle (model 2), and previous accidents in 2012 (model 3). Results Of the safety climate problems reported in 2012, 1017 (28%) participants reported one problem, 357 (10%) reported two and 614 (17%) reported three or more problems. Using the number of safety climate problems as a continuous variable, all models showed a dose-response relationship between number of safety climate problems in 2012 and at least one accident in 2014 (trend-test, P<0.001). Compared to participants with no safety climate problems, participants reporting two safety climate problems in 2012 had a higher risk for reporting an accident in 2014 [OR 1.84, 95% confidence interval (CI) 1.22-2.77], and the risk was higher for participants reporting three or more safety problems (OR 2.22, 95% CI 1.60-3.09). Conclusions A higher number of safety climate problems progressively increased the OR for reporting at least one accident within the last 12 months at the two-year follow-up. The five-item safety climate survey is a simple and important tool that can be used as part of risk assessment in blue-collar workplaces.

AB - INTRODUCTION AND HYPOTHESIS: Urinary incontinence is a prevalent problem in women with spinal cord injury. The aim of this study was to examine the effect of pelvic floor muscle training (PFMT) alone and combined with intravaginal electrical stimulation (IVES) on urinary incontinence in women with incomplete spinal cord injury. METHODS: In this investigator-blinded randomized clinical trial, we recruited women aged 18-75 with incomplete spinal cord injury and urinary incontinence from a single spinal cord injury clinic in Denmark. Women were randomly assigned to either PFMT or PFMT combined with IVES daily at home for 12 weeks. All women were trained by a physiotherapist using vaginal palpation and electromyography biofeedback. Outcome measures were recorded at baseline (week 0), post-intervention (week 12) and follow-up (week 24) and included change in the total score on the International Consultation on Incontinence Questionnaire urinary incontinence short form (ICIQ-UI-SF) and daily episodes of urinary incontinence. RESULTS: From 27 April 2015-9 September 2016, we randomly assigned 36 women (17 in the PFMT group and 19 in the PFMT+IVES group); 27 completed the interventions (13 in the PFMT group and 14 in the PFMT+IVES group). The results showed no difference between the groups on ICIQ-UI-SF or episodes of urinary incontinence at 12 and 24 weeks. Only the PFMT group had a significant change from baseline on ICIQ-UI-SF [-2.4 (95% CI -4.3--0.5), p = 0.018] and daily episodes of urinary incontinence [-0.4 (95% CI -0.8--0.1), p = 0.026] at 12 weeks. CONCLUSIONS: PFMT+IVES is not superior to PFMT alone in reducing urinary incontinence in women with incomplete spinal cord injury. PMID- 29574483 TI - Prevalence of lower urinary tract symptoms and social determinants in primary care users in Brazil. AB - INTRODUCTION AND HYPOTHESIS: Although lower urinary tract symptoms (LUTS) have considerable clinical relevance, few propose evaluating its association with social conditions. Our study aimed to evaluate LUTS prevalence in primary care and its association with the social determinants of health (SDH). METHODS: This is a cross-sectional study conducted with 322 females in the period of June to October 2016 that carried out consultations and screening to prevent gynecological cancer in a primary care unit. RESULTS: The ages ranged from 18 to 85 years (M = 40.53). Storage symptoms had a higher overall prevalence (64.6%), highlighting nocturia (n = 186, 57.8%) and urinary incontinence (n = 120, 37.3%). Storage symptoms were associated with three layers of SDH. The voiding and postmicturition symptoms were only related to operative vaginal delivery. CONCLUSIONS: The findings of this study suggest a relationship between SDH and LUTS. It is important to emphasize that the results not only imply a causal relationship, but also point to the social inequalities existing at a population level.

METHODS: We carried out a multicenter, 12-week, double-blind, randomized, placebo-controlled, parallel design study. Between 2012 and 2015, a total of 118 women (age 18-89 years) with PVD at least twice/weekly, were randomized to receive solifenacin (5 mg; n = 58) or placebo (n = 60) once daily. The primary outcome was the percentage reduction in PVD episodes. Secondary outcomes included the percentage of patients with >=50% reduction in PVD episodes and changes in quality of life. RESULTS: There were no differences in either the primary or secondary outcome variables. Subgroup analysis, based on those with more severe disease (>10 PVD episodes/week), showed a greater and significant percentage reduction in the frequency of PVD episodes per day (60.3% vs 32.1%; p = 0.035) and a higher percentage of patients showing >=50% reduction in the frequency of PVD episodes with solifenacin (68.1% vs 45.8%; p = 0.0476). A significant solifenacin effect occurred at week 2 and continued through week 12 for the subgroup. For solifenacin, PVD reduction was the same for the entire cohort and subgroup, whereas for placebo, it was 10% lower in the subgroup, declining from 42% to 32%. CONCLUSION: There were no differences in PVD outcomes between the solifenacin and placebo groups. Solifenacin may play a role in treating women with the most severe symptoms. Because of the powerful placebo response seen in this study, behavior-based interventions may be useful for treating PVD. PMID- 29574485 TI - Vaginal hysterectomy with apical fixation and anterior vaginal wall repair for prolapse: surgical technique and medium-term results. AB - INTRODUCTION AND HYPOTHESIS: Stabilization of the vaginal apex (level 1) is an important component of operations to correct pelvic organ prolapse (POP). We report functional and anatomical results and patient-reported outcomes of our technique of vaginal vault fixation at the time of vaginal hysterectomy. METHODS: One hundred and nine patients-mean 69 years, range 50.4-83.8; body mass index (BMI) 26.3, range 17.7-39.5-with symptomatic stage 2-3 uterine prolapse combined with stage 3-4 cystocele underwent vaginal hysterectomy with anterior vaginal wall repair; the apex was formed with high closure of the peritoneum and incorporation of the uterosacral and round ligaments. Only absorbable sutures were used. Follow-up included clinical examination with Pelvic Organ Prolapse Quantification system (POP-Q) scoring, introital ultrasonography, quality of life (QoL) Likert scale, and the German Pelvic Floor Questionnaire. RESULTS: Seventy patients (64%) were available for a follow-up after a mean of 2.8 years (range, 1.6-4.2). At follow-up, point C was stage 0 in 55 (78.6%) women and stage 1 in 15 (21.4%). The anterior vaginal wall was stage 0 or 1 in 35 (50%), stage 2 (no cystocele beyond the hymen) in 34 (49%), and stage 3 in 1 (1.4%). Vaginal length (VL) was 9 cm. Four women (4%) were reoperated for prolapse: two for recurrent anterior compartment prolapse and two for de novo rectocele. Postvoid residuals >150 ml were seen in 21(30%) patients preoperatively and resolved postoperatively in 20. Urgency occurred in nine (13%), stress urinary incontinence (SUI) in ten (14%), and nocturia in 19 (27%). No patient had discomfort at the vaginal vault and 62 patients (87%) reported improved QoL, which did not correlate with anatomical results. Cystocele >= 2 degrees at follow-up was associated with BMI >25 (p = 0.03). CONCLUSIONS: Our surgical technique without permanent material offers good apical support and functional and subjective results. Anatomical improvement was achieved in all cases of cystocele repair. Recurrent cystoceles are often asymptomatic. PMID- 29574486 TI - DELLA proteins negatively regulate dark-induced senescence and chlorophyll degradation in Arabidopsis through interaction with the transcription factor WRKY6. AB - KEY MESSAGE: DELLA proteins' negative regulation of dark-induced senescence and chlorophyll degradation in Arabidopsis is through interaction with WRKY6 and thus repression of its transcriptional activities on senescence-related genes. Senescence is an intricate and highly orchestrated process regulated by numerous endogenous and environmental signals. Gibberellins (GAs) and their signaling components DELLA proteins have been known to participate in the regulation of senescence. However, the mechanism of the GA-DELLA system involved in the senescence process remains largely unclear. Darkness is a known environmental factor that induces plant senescence. In this study, exogenous GA3 (an active form of GA) accelerated but paclobutrazol (a specific GA biosynthesis inhibitor) retarded dark-induced leaf yellowing in Arabidopsis. Moreover, the dark-triggered decrease in chlorophyll content, increase in cell membrane leakage, and upregulation of senescence-associated genes were notably impaired in both endogenous GA-decreased mutants ga3ox1/ga3ox2 and ga20ox1/ga20ox2 compared with those in wild-type Col-0. These effects of darkness were enhanced in the quintuple mutant of DELLA genes gai-t6/rga-t2/rgl1-1/rgl2-1/rgl3-1 and conversely attenuated in the gain-of-function mutant gai and transgenic plant 35S::TAP RGAd17 compared with wild-type Ler. Subsequently, RGA interacted with the transcription factor WRKY6 in a yeast two-hybrid assay, as confirmed by bimolecular fluorescence complementation and pull-down analyses. In addition, mutation and overexpression of WRKY6 retarded and accelerated dark-induced senescence, respectively. Furthermore, transient expression assays in Arabidopsis protoplasts indicated that RGA and GAI weakened the transcriptional activities of WRKY6 on its downstream senescence-related genes, including SAG13 and SGR. Taken together, these results suggest that GAs positively and DELLAs negatively regulate dark-induced senescence and chlorophyll degradation in Arabidopsis. DELLAs function in this process, at least in part, by interacting with WRKY6. PMID- 29574487 TI - Isolation, expression, and functional analysis of developmentally regulated plasma membrane polypeptide 1 (DREPP1) in Sporobolus virginicus grown under alkali salt stress. AB - The plant specific DREPP proteins have been shown to bind Ca2+ and regulate the N myristoylation signaling and microtubule polymerization in Arabidopsis thaliana. The information about DREPP proteins in other plants is, however, scarce. In the present study, we isolated the DREPP gene from a halophytic grass, Sporobolus virginicus, and tested whether the gene was involved in alkaline salt stress responses. The SvDREPP1 was cloned from S. virginicus by RACE methods. The isolated gene showed high homology to DREPP homologs from C4 grasses, Setaria italica, and Panicum hallii as well as rice (OsDREPP1). The encoded protein contained 202 amino acid residues. It was expressed in E. coli, and its biochemical properties were studied. It was observed that SvDREPP1 was not only Ca2+-binding protein, but also bind to calmodulin and microtubules. The SvDREPP1 mRNA expression in plants grown under alkaline salt stress was upregulated by 3.5 times over the control in leaf tissues after 48-h treatment, whereas it was increased for 6.0 times in the root tissues at 36 h. The data suggests the importance of SvDREPP1 in regulating alkali salt stress responses in the leaf tissues. PMID- 29574488 TI - Simpson-Golabi-Behmel syndrome human adipocytes reveal a changing phenotype throughout differentiation. AB - The Simpson-Golabi-Behmel syndrome (SGBS) cell strain is widely considered to be a representative in vitro model of human subcutaneous white pre-adipocytes. These cells achieve a transient expression of classical brown markers, such as uncoupling protein 1, peaking at day 14 of differentiation and decreasing thereafter. Adipocyte browning process involves dynamic changes in lipid droplet (LD) dimension, in mitochondria morphology, and in the expression of brown specific marker genes. This study analyzes SGBS transient phenotypic transformation by quantifying the heterogeneity of LDs, mitochondrial dynamics, and a panel of genes involved in adipocyte differentiation and browning. LDs at 21 days of differentiation were larger than in the previous stages, without any change in the number per cell. The expression of genes such as peroxisome peroxisome proliferator-activated receptor gamma, leptin, and lipase E significantly raised from 0 to 21 days. Adiponectin was significantly upregulated at 14 days of differentiation. Brown-specific marker PR domain containing 16 was highly expressed at D0. The variability of mitochondrial shape and interconnectivity reflects differences in the relative rates of fusion and fission, resulting in a significant shift from a networked shape at D7 to a fragmented and swollen one at D14 and D21. The transient phenotype experienced by this cellular model should be considered whether used in studies involving the stimulation of adipocyte browning and could be an interesting human model to further elucidate the browning process in the absence of any stimulation. PMID- 29574489 TI - Pregnancy outcome after first trimester use of angiotensin AT1 receptor blockers: an observational cohort study. AB - BACKGROUND: Ongoing discussion about the safety of renin-angiotensin inhibitors in the first trimester and limited data on pregnancy outcomes after exposure to angiotensin AT1 receptor blockers (ARBs). METHODS: Observational cohort study compares outcomes of 215 prospectively ascertained pregnancies with first trimester exposure to ARBs with 642 non-hypertensive pregnancies. RESULTS: The rate of major birth defects in the ARB cohort (9/168, 5.4%) was higher than in the comparison group (17/570, 3%), but not significantly increased (ORadj 1.9, 95% CI 0.7-4.9). There was no distinct pattern of anomalies among infants with birth defects. The risk of spontaneous abortions was not increased (HRadj 0.9, 95% CI 0.5-1.6), although the cumulative incidence was in the upper normal range (0.22, 95% CI 0.15-0.32). Higher rates of prematurity (ORadj 3.0; 95% CI 1.7-5.1) and a reduced birth weight after adjustment for sex and gestational age were observed. There was no evidence for an increased risk for major birth defects, spontaneous abortions, or preterm birth in a sensitivity analysis comparing ARB exposed hypertensive women to hypertensive women without ARB exposure during the first trimester. CONCLUSION: Our study supports the hypothesis that ARBs are not major teratogens. Patients inadvertently exposed to ARBs during the early pregnancy may be reassured. Nevertheless, women planning pregnancy should avoid ARBs. In selected cases, ARBs might be continued under careful monitoring of menstrual cycle and discontinued as soon as pregnancy is recognized. PMID- 29574490 TI - Kinetic and thermodynamic studies on the enzymatic synthesis of wax ester catalyzed by lipase immobilized on glutaraldehyde-activated rice husk particles. AB - Commercial lipase from Thermomyces lanuginosus has been immobilized on glutaraldehyde-activated rice husk particles via covalent attachment. It was reached maximum immobilized protein concentration of 27.5 +/- 1.8 mg g-1 of dry support using the initial protein loading of 40 mg g-1 of support. The immobilized biocatalyst was used to synthesize cetyl oleate (wax ester) via direct esterification of oleic acid and cetyl alcohol. The influence of relevant factors on ester synthesis, such as reaction temperature, biocatalyst concentration, presence or lack of hydrophobic organic solvents, acid:alcohol molar ratio, and reaction time has been evaluated. The experimental data were well fitted to a second-order reversible kinetic model to determine apparent kinetic constants. Thermodynamic studies have revealed that the reaction was a spontaneous and endothermic process. Under optimal experimental conditions, it was observed maximum ester conversion of 90.2 +/- 0.6% in 9 h of reaction time in hexane medium using 1 M of each reactant (cetyl alcohol and oleic acid), at 50 degrees C and biocatalyst concentration of 15% m/v of reaction mixture. Similar conversion (91.5 +/- 0.8%) in a solvent-free system was also obtained within 24 h of reaction. The biocatalyst retained 85% of its initial activity after 12 cycles within 9 h of reaction in hexane medium. The physicochemical properties of purified ester have been determined in accordance with ASTM standards. The results indicate that the prepared biocatalyst has great potential for wax ester synthesis due to its satisfactory catalytic activity and operational stability.

AB - The anterior aspect of the knee is host to an array of normal variants and potential pathology. These normal anatomic variants are often encountered and may mimic pathologies, leading to unnecessary work-up and treatments. On the other hand, there are several subtle abnormalities that may be easily overlooked or mistaken for variants or other injuries or diseases. Recognition of these diagnostic challenges is essential for radiologists to make an accurate diagnosis. This article reviews normal anatomical variants of ligaments, tendons, bones, and other important structures of the anterior knee, focusing on magnetic resonance imaging features. Commonly encountered injuries and abnormalities of the anterior knee and their diagnostic pitfalls are also discussed, highlighting findings on magnetic resonance imaging. PMID- 29574493 TI - Immigrant Respiratory Health: a Diverse Perspective in Environmental Influences on Respiratory Health. AB - PURPOSE OF REVIEW: The aim of this review is to examine the prevalence of and impact of environmental exposures in the workplace and home on immigrant respiratory health in the USA. RECENT FINDINGS: Few studies report levels of workplace and home environmental exposures for immigrant children and adults, and documenting these findings is an important first step to addressing their respiratory health concerns. Rates of respiratory disease are lowest upon first arrival and increase with duration of residency in the USA. Community Health Workers may be an efficacious intervention to reducing exposures and improving lung health among immigrant populations. Immigrant children and adults have a high risk of occupational and home environmental exposures that can negatively affect their respiratory health. While limited studies exist, more documentation of these exposures and their impact on immigrant person's respiratory health are needed to begin to tackle these disparities. PMID- 29574494 TI - Motion Correction and Its Impact on Absolute Myocardial Blood Flow Measures with PET. AB - PURPOSE OF REVIEW: Motion artifacts, due to cardiac and respiratory cycles, myocardial cardiac creep, or gross patient movements, have been extensively investigated in the context of relative myocardial perfusion imaging with SPECT and PET. These movements have been identified as a major source of errors in image quantification and diagnosis. Recently, as dynamic PET quantification for myocardial blood flow assessment has entered clinical practice, similar questions have arisen on the impact of motion on final blood flow values. RECENT FINDINGS: While preliminary investigations have underlined the potential impact of these motions on MBF quantification, their correction on dynamic acquisition remains challenging and limited to research studies. Gross patient's body movements occur in a consistent number of cases, particularly during stress acquisition, typically involving a limited number of image frames. If undetected, these movements can lead to great differences in flow values and consequently misdiagnosis. Quality control routines can be applied to automatically inspect the shape of time activity curves and to help identify motion artifacts. Cyclic cardiac and respiratory motion may have a considerable impact on final flow values. Correction of gross body motion represents a priority in the context of optimizing absolute flow clinical routine utilization and protocol standardization. PMID- 29574495 TI - Divergence of Funneliformis mosseae populations over 20 years of laboratory cultivation, as revealed by vegetative incompatibility and molecular analysis. AB - Arbuscular mycorrhizal fungi (AMF) are widespread, important plant symbionts. They absorb and translocate mineral nutrients from the soil to host plants through an extensive extraradical mycelium, consisting of indefinitely large networks of nonseptate, multinucleated hyphae which may be interconnected by hyphal fusions (anastomoses). This work investigated whether different lineages of the same isolate may lose the ability to establish successful anastomoses, becoming vegetatively incompatible, when grown separately. The occurrence of hyphal incompatibility among five lineages of Funneliformis mosseae, originated from the same ancestor isolate and grown in vivo for more than 20 years in different European locations, was assessed by systematic detection of anastomosis frequency and cytological studies. Anastomosis frequencies ranged from 60 to 80% within the same lineage and from 17 to 44% among different lineages. The consistent detection of protoplasm continuity and nuclei in perfect fusions showed active protoplasm flow both within and between lineages. In pairings between different lineages, post-fusion incompatible reactions occurred in 6-48% of hyphal contacts and pre-fusion incompatibility in 2-17%. Molecular fingerprinting profiles showed genetic divergence among lineages, with overall Jaccard similarity indices ranging from 0.85 to 0.95. Here, phenotypic divergence among the five F. mosseae lineages was demonstrated by the reduction of their ability to form anastomosis and the detection of high levels of vegetative incompatibility. Our data suggest that potential genetic divergence may occur in AMF over only 20 years and represent the basis for detailed studies on the relationship between genes regulating anastomosis formation and hyphal compatibility in AMF. PMID- 29574496 TI - Impact of soil pedogenesis on the diversity and composition of fungal communities across the California soil chronosequence of Mendocino. AB - Understanding how soil pedogenesis affects microbial communities and their in situ activities according to ecosystem functioning is a central issue in soil microbial ecology, as soils represent essential nutrient reservoirs and habitats for the biosphere. To address this question, soil chronosequences developed from a single, shared mineralogical parent material and having the same climate conditions are particularly useful, as they isolate the factor of time from other factors controlling the character of soils. In our study, we considered a natural succession of uplifted marine terraces in Mendocino, CA, ranging from highly fertile in the younger terrace (about 100,000 years old) to infertile in the older terraces (about 300,000 years old). Using ITS amplicon pyrosequencing, we analysed and compared the diversity and composition of the soil fungal communities across the first terraces (T1 to T3), with a specific focus in the forested terraces (T2 and T3) on soil samples collected below trees of the same species (Pinus muricata) and of the same age. While diversity and richness indices were highest in the grassland (youngest) terrace (T1), they were higher in the older forested terrace (T3) compared to the younger forested terrace (T2). Interestingly, the most abundant ectomycorrhizal (ECM) taxa that we found within these fungal communities showed high homology with ITS Sanger sequences obtained previously directly from ECM root tips from trees in the same study site, revealing a relative conservation of ECM diversity over time. Altogether, our results provide new information about the diversity and composition of the fungal communities as well as on the dominant ECM species in the soil chronosequence of Mendocino in relation to soil age and ecosystem development. PMID- 29574497 TI - Defining the contribution of chronic kidney disease to all-cause mortality in patients with type 2 diabetes: the Renal Insufficiency And Cardiovascular Events (RIACE) Italian Multicenter Study. AB - AIMS: To define the contribution of chronic kidney disease (CKD) to excess mortality in patients with type 2 diabetes and identify the baseline variables associated with all-cause death in those with and without CKD using the RECursive Partitioning and Amalgamation (RECPAM) method. METHODS: This observational, longitudinal, cohort study enrolled 15,773 consecutive non-dialytic patients with type 2 diabetes in 19 Diabetes Clinics throughout Italy in 2006-2008. Based on the presence of albuminuria >= 30 mg day-1 and/or estimated glomerular filtration rate (eGFR) < 60 mL min-1.1.73 m-2 at baseline, patients were classified as having or not CKD. Vital status was verified on October 31, 2015 for 99.26% of patients. RESULTS: Mortality increased with increasing albuminuria and eGFR category. Excess risk versus the general population was maximal in patients aged < 55 years in the worse albuminuria or eGFR category. Conversely, in subjects aged >= 75 years with albuminuria < 10 mg day-1 or eGFR >= 75 mL min-1.1.73 m-2, excess mortality was no longer detectable. At RECPAM analysis, the main correlates of death in the whole cohort were albuminuria > 44 mg day-1, prevalent CVD, and eGFR < ~ 75 mL min-1.1.73 m-2; gender, prevalent CVD, and higher albuminuria in the normoalbuminuric range, in patients without CKD; and CVD, eGFR ~ < 50 mL min-1.1.73 m-2, and albuminuria > 53 mg day-1, in those with CKD. CONCLUSIONS: CKD is a major contributor to excess mortality in type 2 diabetes, conferring a very high risk in younger patients and fully accounting for excess risk in the older ones. Higher albuminuria and lower eGFR, even in the normal range, identify individuals with increased mortality risk.

PMID- 29574498 TI - Pond bank access as an approach for managing toxic cyanobacteria in beef cattle pasture drinking water ponds. AB - Forty-one livestock drinking water ponds in Alabama beef cattle pastures during were surveyed during the late summer to generally understand water quality patterns in these important water resources. Since livestock drinking water ponds are prone to excess nutrients that typically lead to eutrophication, which can promote blooms of toxigenic phytoplankton such as cyanobacteria, we also assessed the threat of exposure to the hepatotoxin, microcystin. Eighty percent of the ponds studied contained measurable microcystin, while three of these ponds had concentrations above human drinking water thresholds set by the US Environmental Protection Agency (i.e., 0.3 MUg/L). Water quality patterns in the livestock drinking water ponds contrasted sharply with patterns typically observed for temperate freshwater lakes and reservoirs. Namely, we found several non-linear relationships between phytoplankton abundance (measured as chlorophyll) and nutrients or total suspended solids. Livestock had direct access to all the study ponds. Consequently, the proportion of inorganic suspended solids (e.g., sediment) increased with higher concentrations of total suspended solids, which underlies these patterns. Unimodal relationships were also observed between microcystin and phytoplankton abundance or nutrients. Euglenoids were abundant in the four ponds with chlorophyll concentrations > 250 MUg/L (and dominated three of these ponds), which could explain why ponds with high chlorophyll concentrations would have low microcystin concentrations. Based on observations made during sampling events and available water quality data, livestock-mediated bioturbation is causing elevated total suspended solids that lead to reduced phytoplankton abundance and microcystin despite high concentrations of nutrients, such as phosphorus and nitrogen. Thus, livestock could be used to manage algal blooms, including toxic secondary metabolites, in their drinking water ponds by allowing them to walk in the ponds to increase turbidity. PMID- 29574499 TI - The correlation between the quality of oral hygiene and oral HPV infection in adults: a prospective cross-sectional study. AB - OBJECTIVES: Various risk factors for oral human papillomavirus (HPV) infections have been described, including tobacco smoking and sexual behavior. However, less is known about the influence of oral health on such infections. The present study aimed to determine a possible association between the quality of oral hygiene and the presence of oral HPV. METHODS: In a prospective analysis, the approximal plaque index (API), the gingival bleeding index (GBI), and the lifetime number of extracted teeth was determined in 187 patients. Additionally, the presence of oral low-risk and/or high-risk HPV was investigated by brush smear testing in all participants. RESULTS: Seventy-four patients had an API < 20%, 84 participants showed an API of 20-40%, and in 29 cases, an API > 40% was recorded. Ninety-six patients presented a GBI < 20%, 75 had a GBI of 20-40%, and 16 showed a GBI > 40%. One hundred four patients had experienced one to three extractions, and 36 had lost more than three teeth. Thirty-nine participants had a positive oral HPV testing (27 high-risk HPV, 26 low-risk HPV, 14 low- and high-risk HPV). A higher API respectively GBI and a greater number of extracted teeth were significantly correlated with the presence of high-risk HPV. The presence of low-risk HPV was significantly higher in patients with API > 40% and GBI > 40% (OR 7.89). Similar results were found regarding the number of extracted teeth. CONCLUSION: The present analysis confirms a relationship between the quality of oral hygiene, determined by objective markers. Thus, improvement of oral health may reduce the incidence of oral HPV infection. CLINICAL SIGNIFICANCE: The present article investigates the relationship between oral hygiene and the presence of oral HPV. As a significant correlation between these two factors could be recorded, improvement of oral hygiene may reduce actively the incidence of oral HPV. Thereby, good oral hygiene may contribute oral cancer prevention. PMID- 29574500 TI - Meaningful Assessment of Robotic Surgical Style using the Wisdom of Crowds. AB - OBJECTIVE: Quantitative assessment of surgical skills is an important aspect of surgical training; however, the proposed metrics are sometimes difficult to interpret and may not capture the stylistic characteristics that define expertise. This study proposes a methodology for evaluating the surgical skill, based on metrics associated with stylistic adjectives, and evaluates the ability of this method to differentiate expertise levels. METHODS: We recruited subjects from different expertise levels to perform training tasks on a surgical simulator. A lexicon of contrasting adjective pairs, based on important skills for robotic surgery, inspired by the global evaluative assessment of robotic skills tool, was developed. To validate the use of stylistic adjectives for surgical skill assessment, posture videos of the subjects performing the task, as well as videos of the task were rated by crowd-workers. Metrics associated with each adjective were found using kinematic and physiological measurements through correlation with the crowd-sourced adjective assignment ratings. To evaluate the chosen metrics' ability in distinguishing expertise levels, two classifiers were trained and tested using these metrics. RESULTS: Crowd-assignment ratings for all adjectives were significantly correlated with expertise levels. The results indicate that naive Bayes classifier performs the best, with an accuracy of [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] when classifying into four, three, and two levels of expertise, respectively. CONCLUSION: The proposed method is effective at mapping understandable adjectives of expertise to the stylistic movements and physiological response of trainees. PMID- 29574501 TI - Analytical Expressions for the Mixed-Order Kinetics Parameters of TL Glow Peaks Based on the two Heating Rates Method. AB - The two heating rates method (originally developed for first-order glow peaks) was used for the first time to evaluate the activation energy (E) from glow peaks obeying mixed-order (MO) kinetics. The derived expression for E has an insignificant additional term (on the scale of a few meV) when compared with the first-order case. Hence, the original expression for E using the two heating rates method can be used with excellent accuracy in the case of MO glow peaks. In addition, we derived a simple analytical expression for the MO parameter. The present procedure has the advantage that the MO parameter can now be evaluated using analytical expression instead of using the graphical representation between the geometrical factor and the MO parameter as given by the existing peak shape methods. The applicability of the derived expressions for real samples was demonstrated for the glow curve of Li2B4O7:Mn single crystal. The obtained parameters compare very well with those obtained by glow curve fitting and with the available published data. PMID- 29574502 TI - Synthesis and antimicrobial evaluation of novel 1,2,4-triazole thioether derivatives bearing a quinazoline moiety. AB - A series of structurally novel 3-thioether-1-(quinazolin-4-yl)-1H-1,2,4-triazol-5 amine derivatives (7a-7r) were designed and synthesized based on a pharmacophore hybrid approach, and screened for their antibacterial and antifungal activities in vitro. All the target compounds were fully characterized through [Formula: see text]H NMR, [Formula: see text]C NMR and HRMS spectra. Among them, the structure of compound 7b was further confirmed via single-crystal X-ray diffraction analysis. The obtained results indicated that several target compounds demonstrated notable inhibition activities against tested phytopathogenic bacteria, using a turbidimetric method. For example, compounds 7d, 7g and 7i exhibited EC[Formula: see text] (half-maximal effective concentration) values of 46.9, 47.8 and 43.2 ug/mL, respectively, against the bacterium Xanthomonas axonopodis pv. citri (Xac), which were more potent than commercial agrobactericide Bismerthiazol (56.9 ug/mL). Moreover, EC[Formula: see text] values of compounds 7a and 7h were found to be 81.6 and 93.1 ug/mL, respectively, against the bacterium Ralstonia solanacearum (Rs), being over twofold more active than commercial agrobactericide Thiodiazole-copper (189.6 ug/mL). Finally, some compounds displayed a certain degree of inhibition activity against tested phytopathogenic fungi at 50 ug/mL. PMID- 29574503 TI - Evidence, Emotion and Eminence: A Qualitative and Evaluative Analysis of Doctors' Skills in Macroallocation. AB - In this analysis of the ethical dimensions of doctors' participation in macroallocation we set out to understand the skills they use, how they are acquired, and how they influence performance of the role. Using the principles of grounded moral analysis, we conducted a semi-structured interview study with Australian doctors engaged in macroallocation. We found that they performed expertise as argument, bringing together phronetic and rhetorical skills founded on communication, strategic thinking, finance, and health data. They had made significant, purposeful efforts to gain skills for the role. Our findings challenge common assumptions about doctors' preferences in argumentation, and reveal an unexpected commitment to practical reason. Using the ethics of Paul Ricoeur in our analysis enabled us to identify the moral meaning of doctors' skills and learning. We concluded that Ricoeur's ethics offers an empirically grounded matrix for ethical analysis of the doctor's role in macroallocation that may help to establish norms for procedure. PMID- 29574505 TI - Hymenobacter agri sp. nov., a novel bacterium isolated from soil. AB - A bacterial isolate was recovered from a soil sample collected in Jeollabuk-do Province, South Korea, and subjected to polyphasic taxonomic assessment. Cells of the isolate, designated strain S1-2-1-2-1T, were observed to be rod-shaped, pink in color, and Gram-stain negative. The strain was able to grow at temperature range from 10 to 30 degrees C, with an optimum of 25 degrees C, and growth occurred at pH 6-8. Comparative 16S rRNA gene sequence analysis showed that strain S1-2-1-2-1T belongs to the genus Hymenobacter, with closely related type strains being Hymenobacter daeguensis 16F3Y-2T (95.8% similarity), Hymenobacter rubidus DG7BT (95.8%), Hymenobacter soli PBT (95.7%), Hymenobacter terrenus MIMtkLc17T (95.6%), Hymenobacter terrae DG7AT (95.3%), and Hymenobacter saemangeumensis GSR0100T (95.2%). The genomic DNA G+C content of strain S1-2-1-2 1T was 63.0 mol%. The main polar lipid of this strain was phosphatidylethanolamine, the predominant respiratory quinone was menaquinone-7, and the major fatty acids were C15:0 iso (27.3%), summed feature 3 (C16:1 omega7c/C16:1 omega6c) (16.5%), C15:0 anteiso (15.3%), and C16:0 (14.7%), supporting the affiliation of this strain with the genus Hymenobacter. The results of this polyphasic analysis allowed for the genotypic and phenotypic differentiation of strain S1-2-1-2-1T from recognized Hymenobacter species. On the basis of its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain S1-2-1-2-1T is considered to represent a novel species of the genus Hymenobacter, for which the name Hymenobacter agri sp. nov. is proposed. The type strain is S1-2-1-2-1T (=KCTC 52739T = JCM 32194T). PMID- 29574504 TI - Ventilatory and cerebrovascular regulation and integration at high-altitude. AB - Ascent to high-altitude elicits compensatory physiological adaptations in order to improve oxygenation throughout the body. The brain is particularly vulnerable to the hypoxemia of terrestrial altitude exposure. Herein we review the ventilatory and cerebrovascular changes at altitude and how they are both implicated in the maintenance of oxygen delivery to the brain. Further, the interdependence of ventilation and cerebral blood flow at altitude is discussed. Following the acute hypoxic ventilatory response, acclimatization leads to progressive increases in ventilation, and a partial mitigation of hypoxemia. Simultaneously, cerebral blood flow increases during initial exposure to altitude when hypoxemia is the greatest. Following ventilatory acclimatization to altitude, and an increase in hemoglobin concentration-which both underscore improvements in arterial oxygen content over time at altitude-cerebral blood flow progressively decreases back to sea-level values. The complimentary nature of these responses (ventilatory, hematological and cerebral) lead to a tightly maintained cerebral oxygen delivery while at altitude. Despite this general maintenance of global cerebral oxygen delivery, the manner in which this occurs reflects integration of these physiological responses. Indeed, ventilation directly influences cerebral blood flow by determining the prevailing blood gas and acid/base stimuli at altitude, but cerebral blood flow may also influence ventilation by altering central chemoreceptor stimulation via central CO2 washout. The causes and consequences of the integration of ventilatory and cerebral blood flow regulation at high altitude are outlined. PMID- 29574506 TI - Time from colorectal cancer diagnosis to laparoscopic curative surgery-is there a safe window for prehabilitation? AB - BACKGROUND: There is a growing interest in the adoption of formal prehabilitation programmes prior to elective surgery but regulatory targets mandate prompt treatment following cancer diagnosis. We aimed to investigate if time from diagnosis to surgery is linked to short- and long-term outcomes. METHODS: An exploratory analysis was performed utilising a dedicated, prospectively populated database. Inclusion criteria were biopsy-proven colorectal adenocarcinoma undergoing elective laparoscopic surgery with curative intent. Demographics, date of diagnosis and surgery was captured with patients dichotomised using 4-, 8- and 12-week time points. All patients were followed in a standardised pathway for 5 years. Overall survival was assessed with the Kaplan-Meier log-rank method. RESULTS: Six hundred sixty-eight consecutive patients met inclusion criteria. Mean time from diagnosis to surgery was 53 days (95% CI 48.3-57.8). Identified risk factors for longer time to surgery were males (OR 1.92 [1.2-3.1], p = 0.008), age <= 65 (OR 1.9 [1.2-3], p = 0.01), higher ASA scores (p = 0.01) stoma formation (OR 6.9 [4.1-11], p < 0.001) and neoadjuvant treatment (OR 5.06 [3.1 8.3], p < 0.001). There was no association between time to surgery and BMI (p = 0.36), conversion (16.3%, p = 0.5), length of stay (p = 0.33) and readmission or reoperation (p = 0.3). No differences in five-year survival were seen in those operated within 4, 8 and 12 weeks (p = 0.397, p = 0.962 and p = 0.611, respectively). Multivariate analysis showed time from diagnosis to surgery was not associated with five-year overall survival (HR 0.99, p = 0.52). CONCLUSION: Time from colorectal cancer diagnosis to curative laparoscopic surgery did not impact on overall survival. This finding may allow preoperative pathway alteration without compromising safety. PMID- 29574508 TI - Scopoletin intervention in pancreatic endoplasmic reticulum stress induced by lipotoxicity. AB - Endoplasmic reticulum (ER), a dynamic organelle, plays an essential role in organizing the signaling pathways involved in cellular adaptation, resilience, and survival. Impairment in the functions of ER occurs in a variety of nutritive disorders including obesity and type 2 diabetes. Here, we hypothesize that (scopoletin) SPL, a coumarin, has the potential to alleviate ER stress induced in vitro and in vivo models by lipotoxicity. To test this hypothesis, the ability of SPL to restore the levels of proteins of ER stress was analyzed. Rat insulinoma 5f (RIN5f) cells and Sprague Dawley rats were the models used for this study. Groups of control and high-fat, high-fructose diet (HFFD)-fed rats were treated with either SPL or 4-phenylbutyric acid. Status of ER stress was enumerated by quantitative RT-PCR, Western blot, electron microscopic, and immunohistochemical studies. Proximal proteins of ER stress inositol requiring enzyme 1 (IRE1), protein kinase like endoplasmic reticulum kinase (PERK), and activating transcription factor 6 (ATF6) were reduced in the beta-cells by SPL. The subsequent signaling proteins X-box binding protein 1, eukaryotic initiation factor2alpha, activating transcription factor 4, and C/EBP homologous protein were also suppressed in their expression levels when treated with SPL. IRE1, PERK signaling leads to c-Jun-N-terminal kinases phosphorylation, a kinase that interrupts insulin signaling, which was also reverted upon scopoletin treatment. Finally, we confirm that SPL has the ability to suppress the stress proteins and limit pancreatic ER stress which might help in delaying the progression of insulin resistance. PMID- 29574507 TI - New steps for treating alcohol use disorder. AB - Alcohol use disorder is a complex syndrome with multiple treatment points including drug-induced pathology, withdrawal management, behavioral/cognitive strategies, and relapse prevention. These different components may be complicated by genotype and phenotype. A huge milestone for the treatment of alcohol use disorder across several countries in the last 10 years was the introduction of practice guidelines integrating clinical expertise and research evidence. These provide a summary of interventions that have been shown to be effective following rigorous and replicated clinical trials. Inspection of these guidelines reveals good consistency, but little evidence of progress in treatment approaches for alcohol use disorder over the past decade. In this mini-review, we discuss emerging treatments for alcohol use disorder that may supplement or improve the evidence-based treatments that are currently recommended. New medications, the emergence of digital technology, and other novel approaches such as transcranial magnetic stimulation are all discussed with reference to treatments already in practice. We also consider how individual differences in genotype and phenotype may affect outcomes. Together with improvements in technology, this knowledge offers a powerful tool for designing personalized approaches to treatment, and hence improving prognosis for rehabilitation programs. PMID- 29574509 TI - Linkage disequilibrium and functional analysis of PRE1 insertion together with SNPs in the promoter region of IGFBP7 gene in different pig breeds. AB - Polymorphisms in regions upstream of transcription initiation site may modify the transcriptional activity of target genes by changing promoter activity. This study aims to determine whether or not polymorphisms at porcine IGFBP7 promoter region affect gene expression. In this study, eight SNPs and one PRE1 insertion in this region were first confirmed. The PRE1 insertion was widespread in 20 Chinese indigenous breeds, but was not observed in three commercial breeds. A perfect linkage disequilibrium, consisting of six of those SNPs and a PRE1, was observed with two haplotypes (h1 and h2) in five pig breeds. The h1 haplotype had an overwhelming superiority distribution in Large White, Landrace, and Bama mini pig; in turn, the h2 only existed in the PRE1 presence breeds. As the haplotypes and PRE1 were located at gene promoter regions, we further investigated the transfection of plasmids with three different fragments of IGFBP-7 promoter region (H1, H2, RF). The CMV promoter of the pEGFP-N1 was substituted by these three different fragments, respectively. Different transcriptional and translational activities of EGFP in PK-15 cells were observed in these three recombinant plasmids by quantitative real-time PCR and flow cytometric analysis. The results indicated that H1 had the higher transcriptional and translational activities of EGFP as compared to the H2 (P < 0.05, P < 0.05). As compared to the RF group, EGFP mRNA expression level was significantly higher in H1 groups (P < 0.05). The IGFBP-7 promoter polymorphisms detected in this study may be important functional variants and potential genetic markers for pig population genetic study. PMID- 29574510 TI - MicroRNA-499a-5p Promotes Differentiation of Human Bone Marrow-Derived Mesenchymal Stem Cells to Cardiomyocytes. AB - Since the adult mammalian heart has limited regenerative capacity, cardiac trauma, disease, and aging cause permanent loss of contractile tissue. This has fueled the development of stem cell-based strategies to provide the damaged heart with new cardiomyocytes. Bone marrow-derived mesenchymal stem cells (BM-MSCs) are capable of self-renewal and differentiation into cardiomyocytes, albeit inefficiently. MicroRNAs (miRNAs, miRs) are non-coding RNAs that have the potential to control stem cell fate decisions and are employed in cardiac regeneration and repair. In this study, we tested the hypothesis that overexpression of miR-499a induces cardiomyogenic differentiation in BM-MSCs. Human BM-MSCs (hBM-MSCs) were transduced with lentiviral vectors encoding miR 499a-3p or miR-499a-5p and analyzed by immunostaining and western blotting methods 14 days post-transduction. MiR-499a-5p-transduced cells adopted a polygonal/rod-shaped (myocyte-like) phenotype and showed an increase in the expression of the cardiomyocyte markers alpha-actinin and cTnI, as cardiogenic differentiation markers. These results indicate that miR-499a-5p overexpression promotes the cardiomyogenic differentiation of hBM-MSCs and may thereby increase their therapeutic efficiency in cardiac regeneration. PMID- 29574511 TI - Small Ubiquitin-Like Modifier Protein 3 Enhances the Solubilization of Human Bone Morphogenetic Protein 2 in E. coli. AB - Small ubiquitin-like modifier (SUMO) fusion technology is widely used in the production of heterologous proteins from prokaryotic system to aid in protein solubilization and refolding. Due to an extensive clinical application of human bone morphogenetic protein 2 (hBMP2) in bone augmentation, total RNA was isolated from human gingival tissue and mature gene was amplified through RT-PCR, cloned (pET21a), sequence analyzed, and submitted to GenBank (Accession no. KF250425). To obtain soluble expression, SUMO3 was tagged at the N-terminus of hBMP2 gene (pET21a/SUMO3-hBMP2), transferred in BL21 codon+, and ~ 40% soluble expression was obtained on induction with IPTG. The dimerized hBMP2 was confirmed with Western blot, native PAGE analysis, and purified by fast protein liquid chromatography with 0.5 M NaCl elution. The cleavage of SUMO3 tag from hBMP2 converted it to an insoluble form. Computational 3D structural analysis of the SUMO3-hBMP2 was performed and optimized by molecular dynamic simulation. Protein protein interaction of SUMO3-hBMP2 with BMP2 receptor was carried out using HADDOCK and inferred stable interaction. The alkaline phosphatase assay of SUMO3 hBMP2 on C2C12 cells showed maximum 200-ng/ml dose-dependent activity. We conclude that SUMO3-tagged hBMP2 is more suited for generation of soluble form of the protein and addition of SUMO3 tag does not affect the functional activity of hBMP2.

AB - INTRODUCTION: The purpose of this study was to evaluate the results achieved after the use of lateral minimally invasive plate osteosynthesis (MIPO) in oligotrophic humerus nonunions resulting from failed intramedullary nailing (IM). METHOD: We evaluated nine patients with humerus nonunion after failed locked intramedullary nailing, all treated using 3.5-mm locked compression plates (LCP) placed through lateral minimally invasive approaches, between 2010 and 2016. Patient's age averaged 39.7 years. All nonunions were diaphyseal and oligotrophic. All nonunions had previous surgical treatment with static locked nails (seven antegrade and two retrograde). The IM nails were all well inserted in the humerus (none of them protruded or had rotator cuff lesions associated). Pre-operative Disabilities of the Arm, Shoulder and Hand (DASH) score averaged 25.5 points. Pre-operative Constant's score averaged 80.2. Pre-operative visual analog scale of pain averaged 2.4 points. RESULTS: Follow-up averaged 17.7 months. Time between initial surgery and revision procedure averaged 11.7 months. Union was achieved in all cases, after an average of 4.8 months. DASH score at last follow-up averaged 5.1 points, and final Constant's score averaged 93.7 points. The analog scale of pain averaged 0.7 points. Time from definitive surgery to work return averaged 3.9 months. Long 3.5-mm LCPs were used (plate length averaged 16.9 screw holes). In two cases, a third 4-cm incision at the nonunion site was performed and cancellous autologous iliac crest bone graft was associated. CONCLUSION: In our series of nine patients, we achieved union and good objective and subjective results, with high patient satisfaction, using a lateral MIPO technique and placing long 3.5-mm LCPs in selected oligotrophic humerus nonunions after failed IM nailing. PMID- 29574513 TI - Insights into phytase-containing transgenic Lemna minor (L.) as a novel feed additive. AB - This study assessed the effect of supplementation of novel transgenic phytase on growth performance and bone mineralization in Korean native broiler chickens. The experiment was designed using four dietary groups: those with a diet supplemented with (A) recombinant phytase, (B) transgenic phytase from the plant Lemna minor, (C) or wild-type L. minor as well as (D) a control group that was supplemented with commercially available feed. Three hundred 1-day-old Korean native broiler chicks were used and divided into these four dietary treatment groups having three replicates of 25 birds each (n = 75). The results showed increases in growth performance and bone mineralization in Groups B and C; compared with Groups A and D. Hematological analyses revealed notable contrasts in erythrocyte sedimentation rate, red blood cell count, and hemoglobin levels among the experimental groups, whereas no impacts of dietary treatment were observed on total eosinophil, lymphocyte, heterophil, monocyte, and basophil levels. The relative expression profiling of candidate genes showed that the genes involved in growth response, meat quality, and P-Ca metabolism were significantly highly expressed in the phytase-supplemented groups. Hence, it is suggested that dietary supplementation with transgenic phytase plant L. minor for enhancing growth performance is a promising new approach in the broiler feed industry. To the best of our knowledge, we report here the most comprehensive analysis using a broiler model that provides a workable platform for further research on the cost effective production of feed with different compositions that might be beneficial in the livestock feed industry. PMID- 29574514 TI - Longitudinal study for anthelmintic efficacy against intestinal helminths in naturally exposed Lithuanian village dogs: critical analysis of feasibility and limitations. AB - The efficacy of anthelmintic treatment at 1, 3, and 6 month intervals was evaluated in a prospective controlled field study with naturally exposed Lithuanian village dogs by monthly coproscopy during 1 year. A placebo-treated control group (C) (n = 202) and groups treated with two broad-spectrum anthelmintics, febantel/pyrantel-embonate/praziquantel (Drontal(r) Plus, Bayer) (D1, D3, D6; n = 113-117) and emodepside/praziquantel (Profender(r), Bayer) (P1, P3, P6; n = 114-119), were included. At the beginning of the study, eggs of Toxocara canis (4.02%) and T. cati (0.44%) identified morphometrically and/or molecularly and eggs of taeniid- (0.78%) and Capillaria-like eggs (5.03%) were present in the feces without significant differences in prevalence between groups. Significant decreases in excretion of T. canis eggs was found 1 month after the treatment with Drontal(r) Plus in February (D1) and with Profender(r) in October (P1), November (P1), December (P3), February (P1), and March (P1, P3), as compared to controls in the same months. The incidence of egg excretion per dog at least once a year was significantly lower in group P1 for T. canis (4.24%; p < 0.01) and in groups D1, P1 for taeniid eggs (0%; p < 0.01 and p < 0.001), when compared to controls (16.96 and 6.70%, respectively). A critical analyses of factors possibly responsible for intestinal passage of canine helminth eggs revealed that chained dogs excreted T. canis eggs more frequently 1 month after treatment compared to dogs in pens, particularly from November to March (p = 0.01). The incidence of single detection of T. cati eggs was significantly increased in chained dogs (12.46%) as compared to fenced dogs (1.08%; p = 0.0001). PMID- 29574515 TI - A regional algorithm to model mesozooplankton biomass along the southwestern Bay of Bengal. AB - A three-dimensional regression analysis attempted to model mesozooplankton (MSP) biomass using sea surface temperature (SST) and chlorophyll-a (Chl-a). The study was carried out from January 2014 to July 2015 in the southwestern Bay of Bengal (BoB) and sampling was carried out on board Sagar Manjusha and Sagar Purvi. SST ranged from 26.2 to 33.1 degrees C while Chl-a varied from 0.04 to 6.09 MUg L-1. During the course of the study period, there was a weak correlation (r = 0.32) between SST and Chl-a statistically. MSP biomass varied from 0.42 to 9.63 mg C m 3 and inversely related with SST. Two kinds of approaches were adopted to develop the model by grouping seasonal datasets (four seasonal algorithms) and comprising all datasets (one annual algorithm). Among the four functions used (linear, paraboloid, the Lorentzian and the Gaussian functions), paraboloid model was best suited. The best seasonal and annual algorithms were applied in the synchronous MODIS-derived SST and Chl-a data to estimate the MSP biomass in the southwestern BoB. The modelled MSP biomass was validated with field MSP biomass and the result was statistically significant, showing maximum regression coefficient for the seasonal algorithms (R2 = 0.60; p = 0.627; alpha = 0.05), than the annual algorithm (R2 = 0.52; p = 0.015, alpha = 0.05). PMID- 29574517 TI - Impact of switching oral bisphosphonates to denosumab or daily teriparatide on the progression of radiographic joint destruction in patients with biologic-naive rheumatoid arthritis. AB - : In biologic-naive female RA patients, switching oral BPs to DMAb significantly reduced radiographic joint destruction compared to continuing oral BPs or switching to TPTD at 12 months, which were significantly associated with a decrease of a bone resorption marker at 6 months. INTRODUCTION: The aim of this study was to clarify the effects of switching oral bisphosphonates (BPs) to denosumab (DMAb) or daily teriparatide (TPTD) on the progression of radiographic joint destruction in patients with biologic-naive rheumatoid arthritis (RA). METHODS: A retrospective, case-controlled study involving 90 female RA patients (mean age 68.2 years, 96.7% postmenopausal, disease activity score assessing 28 joints with CRP (DAS28-CRP) 2.4, methotrexate treatment 81.1%, prednisolone treatment 68.9%, and prior BP treatment 44.8 months), who were allocated depending on each patient's and physician's wishes, to (1) the BP-continue group (n = 30), (2) the switch-to-DMAb group (n = 30), or (3) the switch-to-TPTD group (n = 30), was conducted. Patients were retrospectively selected to minimize the difference of possible clinical backgrounds that may affect the joint destruction of RA. The primary endpoint was to clarify the change of the modified total Sharp score (mTSS) from baseline to 12 months. RESULTS: After 12 months, the mean changes of the modified Sharp erosion score were significantly lower in the switch-to-DMAb group (0.2 +/- 0.1; mean +/- standard error) than in the switch-to TPTD group (1.3 +/- 0.5; P < 0.05), and mTSS was significantly lower in the switch-to-DMAb group (0.3 +/- 0.2) than in the BP-continue group (1.0 +/- 0.3; P < 0.05) and the switch-to-TPTD group (1.7 +/- 0.6; P < 0.05). The logistic regression analysis showed that mTSS changes were significantly associated with the percent changes of TRACP-5b at 6 months (beta = 0.30, 95% CI = 0.002-0.016; P < 0.01). CONCLUSIONS: Changes of systemic bone turnover induced by switching BPs to DMAb or TPTD may affect not only systemic bone mass, but also local joint destruction, and its clinical relevance should be considered comprehensively. PMID- 29574516 TI - Risk of fragility fracture among patients with late-onset psoriasis: a UK population-based study. AB - : This study aimed to examine fracture risk in patients with late-onset psoriasis. A cohort study was conducted using primary care records from the Clinical Practice Research Datalink. Psoriasis patients had a 10% increased risk of fracture compared to matched controls (hazard ratio (HR) = 1.10; 95% confidence interval (CI) 1.04, 1.16). INTRODUCTION: This study aimed to examine fracture risk in patients with late-onset psoriasis and investigate the effect of methotrexate on fracture risk. METHODS: A cohort study was conducted using primary care records from the UK-based Clinical Practice Research Datalink. Individuals aged 40 years and over, with incident (new onset) diagnoses of psoriasis, were identified from 1990 to 2004 and followed up until 2015. For each exposed individual, up to four age-, gender-, and practice-matched controls were randomly selected. Incidence rates of fragility fracture (hip, vertebral, spine, radius or unspecified site) per 10,000 person-years were calculated and hazard rates were compared to the unexposed using Cox regression models. The risk of fracture was also estimated, within the exposed group for patients receiving/not receiving methotrexate. RESULTS: Twenty-four thousand two hundred nineteen patients with psoriasis and 94,820 controls were identified. The absolute rate of fracture in psoriasis patients was 58 per 10,000 person-years (95% CI 55, 61) and 53 per 10,000 person-years in the matched controls (CI 52, 54). Psoriasis patients had a 10% increased risk of fracture compared to their matched controls (HR = 1.10; 95% CI 1.04, 1.16). Methotrexate use was not associated with increased risk (HR = 0.91; 95% CI 0.72, 1.15). CONCLUSIONS: Identifying additional clinical factors associated with increased fracture risk is important in improving fracture risk stratification. Further work is needed to determine the relationship between age of onset of psoriasis and fracture risk, explore causative explanations, and identify if existing fracture risk stratification tools underestimate fracture risk in patients with psoriasis. PMID- 29574518 TI - Effects of once-monthly minodronate versus risedronate in osteoporosis patients with rheumatoid arthritis: a 12-month randomized head-to-head comparison. AB - : A head-to-head comparison of once-monthly oral bisphosphonates minodronate (MIN) and risedronate (RIS) in patients with rheumatoid arthritis (RA) demonstrated that MIN has the same effect as RIS on increase in bone mineral density (BMD) and a stronger effect on inhibition of bone resorption than RIS, suggesting that MIN is a promising treatment option for osteoporosis patients with RA. INTRODUCTION: To evaluate the effect of once-monthly oral MIN in patients with RA, a prospective, randomized, open-label, head-to-head comparison with once-monthly oral RIS was conducted. METHODS: A total of 83 patients with RA were randomly assigned to either once-monthly oral MIN 50 mg (n = 42) or once monthly oral RIS 75 mg (n = 41). Serial BMD and bone turnover markers were measured and compared between the treatment groups. RESULTS: BMD (lumbar spine, total hip, femoral neck) increased significantly after 12 months of treatment with MIN (3.8, 2.0, and 2.2%, respectively, P < 0.05) and RIS (3.6, 1.9, and 1.9%, respectively, P < 0.05). There were no significant differences between the treatment groups. Percent changes of bone turnover markers from baseline to 12 months in the MIN group were significantly greater than those in the RIS group (TRACP-5b: - 36.3 vs - 19.3%, P < 0.05; NTX: - 27.1 vs - 17.3%, P < 0.05; BAP: 30.2 vs -19.4%, P < 0.05). CONCLUSIONS: The present study of RA patients demonstrated that MIN has the same effect as RIS on increase in BMD and a stronger effect on inhibition of bone resorption than RIS. The results suggest that MIN is a promising treatment option for osteoporosis patients with RA. PMID- 29574519 TI - Thiazide diuretic usage and risk of fracture: a meta-analysis of cohort studies. AB - : Inconsistent findings in regard to association between thiazide diuretic use and the risk of fracture have been reported during the past decade. This updated meta-analysis, which pooled data from 11 qualified prospective designed studies, found that thiazides have a significant protective effect on fracture risk. INTRODUCTION: An updated comprehensive meta-analysis examine the association between thiazide diuretic use and therisk of fracture is needed. METHODS: Cohort studies regarding thiazide diuretic exposure and the risk of fracture, published from inception to May 1 2017, were identified through MEDLINE, EMBASE, SCOPUS, and the Cochrane Database of Systematic Reviews. The literature search, study selection, study appraisal, and data extraction were pre-defined in the protocol and were independently conducted by two investigators. Due to the heterogeneity of the original studies, a random effects model was used to pool the confounder adjusted relative risk (RR). RESULTS: Eleven eligible cohort studies involving 2,193,160 participants were included for analysis. Overall, thiazide diuretic users, as compared with non-users, had a significant 14% reduction in the risk of all fractures (relative risk [RR], 0.86; 95% confidence interval [CI], 0.80-0.93; p = 0.009) and an 18% reduction in the risk of hip fracture (RR, 0.82; 95%CI, 0.80-0.93; p = 0.009). However, the effect size associated with thiazide use became slightly weaker when the analysis was limited to only high-quality original studies (quality score > 8) (RR, 0.89; 95%CI, 0.80-0.99; p = 0.005), studies with a larger sample size (> 10,000) (RR, 0.90; 95%CI, 0.80-1.00; p = 0.002), and studies published after 2007 (RR, 0.92; 95%CI, 0.82-1.02; p = 0.001). CONCLUSION: Our findings indicate that thiazide diuretic use may convey a decreased risk of fracture and as such, the protective effect of this class of medicine should be considered when prescribing thiazide diuretics in clinical practice. PMID- 29574520 TI - Sleep duration and the risk of osteoporosis among middle-aged and elderly adults: a dose-response meta-analysis. AB - It remains unclear how many hours of sleep are associated with the lowest risk of osteoporosis. This meta-analysis was performed to assess the dose-response relationship between sleep duration and risk of osteoporosis. PubMed and Web of Science were searched from inception to December 3, 2017, supplemented by manual searches of the bibliographies of retrieved articles. Data were pooled using fixed- and random-effects models. Restricted cubic spline analysis with four knots was used to model the sleep duration and osteoporosis association. Four cross-sectional studies with eight records were eligible for inclusion in the meta-analysis. A U-shaped dose-response relationship was observed between sleep duration and risk of osteoporosis, with the lowest risk observed at a sleep duration category of 8-9 h per day. Compared with 8-h sleep duration per day, the pooled odds ratio for osteoporosis were 1.03 (95% CI 1.01-1.06) for each 1-h reduction among individuals with shorter sleep duration and 1.01 (95% CI 1.00 1.02) for each 1-h increment among individuals with longer sleep duration. Our dose-response meta-analysis shows a U-shaped relationship between sleep duration and risk of osteoporosis, with the lowest osteoporosis risk at about 8 h per day of sleep duration. Both short and long sleep duration is associated with a significantly increased risk of osteoporosis in the middle-aged and elderly adults, appropriate sleep duration could help for delay or prevention of osteoporosis. PMID- 29574521 TI - Could bioelectric impedance spectroscopy (BIS) measured appendicular intracellular water serve as a lean mass measurement in sarcopenia definitions? A pilot study. AB - : DXA lean mass measurement for sarcopenia diagnosis is not always possible. Bioelectric impedance spectroscopy (BIS), a portable technology, is a potential alternative to DXA-measured lean mass. This pilot study explores the possibility and proposes an arbitrarily chosen potential cut-point for appendicular intracellular water corrected by height (aICW/ht2). INTRODUCTION: Sarcopenia definitions often include DXA lean mass measurement. However, DXA is not always available. We explored the potential of a less-expensive mobile method, bioelectric impedance spectroscopy (BIS), to assess lean mass for sarcopenia determination. We hypothesized that BIS-measured appendicular intracellular water (aICW/ht2) would correlate with DXA-measured appendicular lean mass (ALM)/ht2 and with functional parameters. If so, establishing an aICW/ht2 cut-point in sarcopenia definitions may be feasible. METHODS: Sixty-one community-dwelling women, mean age 79.9, had BIS and DXA lean mass, grip strength, gait speed, and jumping mechanography assessments. BIS aICW was calculated using limb length and intracellular water resistance. aICW/ht2 was compared to DXA-measured ALM/ht2 by linear regression. The European Working Group ALM/ht2 and an exploratory aICW/ht2 cut-point were utilized. RESULTS: In this cohort, ALM/ht2 and aICW/ht2 were moderately correlated, R2 = 0.55, p < 0.0001. Lean mass was low in 7 and normal in 44 by BIS and DXA. Those with low aICW/ht2 had lower grip strength (p = 0.04) and jump power (p = 0.0002) than those with normal aICW/ht2 and ALM/ht2. Subjects with low ALM/ht2 had lower jump power (p = 0.0006) but were not different in gait speed or grip strength. CONCLUSIONS: BIS aICW is correlated with DXA-measured ALM directly, and when height adjusted. An aICW/ht2 cut-point of 6.5 L/m2 identified 70% of women with low ALM/ht2. Women with low lean mass by DXA and BIS had poorer function measured by jump power. These pilot data support further evaluation of BIS measurement inclusion into sarcopenia definitions. PMID- 29574522 TI - Number of acinar cells at the pancreatic stump predicts pancreatic fistula after pancreaticoduodenectomy. AB - PURPOSE: To establish if the number of pancreatic acinar cells at the pancreatic cut end is a predictor of postoperative pancreatic fistula (POPF). METHODS: The number of acinar cells was assessed histologically in 121 consecutive patients who underwent pancreaticoduodenectomy (PD) between April, 2012 and July, 2016. RESULTS: POPF developed in 23 of the 121 patients. Univariate analysis revealed that male sex, long operating time, high volume of blood loss, soft remnant pancreas, large pancreatic duct, and the number of pancreatic acinar cells were significantly associated with POPF. Multivariate analysis revealed that male sex (p = 0.022) and the number of pancreatic acinar cells (p < 0.0001) were independently associated with POPF. In the receiver operating characteristic (ROC) curve analysis, the area under curve was 0.83895 when the cut off value of the number of pancreatic acinar cells to predict POPF was 890. Sensitivity and specificity of the number of pancreatic acinar cells were 82.6 and 77.6%, respectively. CONCLUSIONS: A large number of pancreatic acinar cells at the cut end of the stump is predictive of POPF after PD. Although POPF is associated with multiple factors and the number of acinar cells is only one of these, our study is the first to confirm this common intuition of surgeons, which has not been assessed definitively before. PMID- 29574523 TI - Alcohol consumption and early-onset risk of colorectal cancer in Japanese patients with Lynch syndrome: a cross-sectional study conducted by the Japanese Society for Cancer of the Colon and Rectum. AB - We conducted this study to establish whether drinking alcohol alters the risk of early-onset colorectal cancer (CRC) in Japanese patients with Lynch syndrome (LS). The subjects were 66 LS patients with pathogenic mutation of mismatch repair genes (MLH1, MSH2, and MSH6) from the nationwide Japanese retrospective multicenter study. Cox proportional hazards modeling was used to investigate the factors correlating with early-onset CRC diagnosis, using clinical data such as gender, tobacco use, alcohol consumption, body mass index, gene mutation (MLH1, MSH2 vs MSH6), and family cancer history. Alcohol was significantly correlated with an increased risk of early-onset CRC [HR 2.44, 95% CI 1.13-5.16 (p = 0.02)], but tobacco use was not [HR 0.8, 95%CI 0.38-1.62 (p = 0.53)]. These findings suggest that alcohol consumption is correlated with an earlier onset of CRC in Japanese patients with LS.

AB - PURPOSE OF REVIEW: The objectives of this review were to (1) discuss how multimorbidity and polypharmacy contributes to the complexity of management among individuals with AF and (2) identify any interventions to manage polypharmacy in relation to AF. RECENT FINDINGS: Based on the four landmark clinical trials of novel anticoagulants, the most common comorbidities with AF are hypertension, heart failure, diabetes, stroke and myocardial infarction. Polypharmacy was also found prevalent in 76.5% of patients with AF, with a median of six drugs per patient. Despite the consequences of polypharmacy in AF, there is very little evidence-based intervention designed to manage it. Hence, there is a need for further research to examine interventions to manage polypharmacy in relation to AF. Atrial fibrillation (AF) is the most common type of cardiac arrhythmia requiring treatment in adults. Due to the structural and/or electrophysiological abnormalities that occur in AF, patients are managed through the use of prophylactic anticoagulant and rate and/or rhythm control medications. However, these medications are considered high risk and can increase the chances of medication misadventure. Additionally, AF rarely occurs in isolation and is known to coexist with multiple other medical comorbidities, i.e. multimorbidity. This also increases the number of medications, i.e. polypharmacy and pill burden which results in treatment non-compliance to prescribed therapy. PMID- 29574525 TI - The putative leucine sensor Sestrin2 is hyperphosphorylated by acute resistance exercise but not protein ingestion in human skeletal muscle. AB - PURPOSE: Dietary protein and resistance exercise (RE) are both potent stimuli of the mammalian target of rapamycin complex 1 (mTORC1). Sestrins1, 2, 3 are multifunctional proteins that regulate mTORC1, stimulate autophagy and alleviate oxidative stress. Of this family, Sestrin2 is a putative leucine sensor implicated in mTORC1 and AMP-dependent protein kinase (AMPK) regulation. There is currently no data examining the responsiveness of Sestrin2 to dietary protein ingestion, with or without RE. METHODS: In Study 1, 16 males ingested either 10 or 20 g of milk protein concentrate (MPC) with muscle biopsies collected pre, 90 and 210 min post-beverage consumption. In Study 2, 20 males performed a bout of RE immediately followed by the consumption of 9 g of MPC or carbohydrate placebo. Analysis of Sestrins, AMPK and antioxidant responses was examined. RESULTS: Dietary protein ingestion did not result in Sestrin2 mobility shift. After RE, Sestrin2 phosphorylation state was significantly altered and was not further modified by post-exercise protein or carbohydrate ingestion. With RE, AMPK phosphorylation remained stable, while the mRNA expressions of several antioxidants were upregulated. CONCLUSIONS: Dietary protein ingestion did not affect the signalling by the family of Sestrins. With RE, Sestrin2 was hyperphosphorylated, with no further evidence of a relationship to AMPK signalling. PMID- 29574526 TI - Differential item functioning for items in Berger's HIV Stigma Scale: an analysis of cohorts from the Indian, Swedish, and US contexts. AB - PURPOSE: To examine whether items in Berger's HIV Stigma Scale function differently with persons of different age, gender, and cultural backgrounds. METHODS: Secondary data from cohorts, collected in South India (n = 250), Sweden (n = 193), and the US (n = 603) were reanalyzed to evaluate DIF within, between, and across these cohorts. All participants had answered the revised version of the HIV stigma scale consisting of 32 items forming the subscales Personalized stigma, Disclosure concerns, Concerns about public attitudes, and Negative self image. Differential Item Functioning (DIF) for these items was assessed using hybrid ordinal regression-IRT technique. When DIF was detected, the cumulative impact of DIF on individual subscale scores was evaluated. RESULTS: DIF was detected for 9 items within, between, or across cohorts, but the DIF was negligible in general. Detected DIF between the Swedish and Indian cohorts had a cumulative salient impact on individual scores for the subscale Disclosure Concerns; Disclosure concerns were overestimated in the Swedish cohort and both over- and underestimated in the Indian cohort. CONCLUSIONS: The items in the 32 item version of the HIV stigma scale did not seem to be particularly prone to present DIF. The DIF between the Indian and Swedish cohort for items in the subscale Disclosure Concerns could, however, result in both type I and type II errors if scores should be compared between the Indian and Swedish cohort. PMID- 29574528 TI - MicroRNA expression profile of thyroid nodules in fine-needle aspiration cytology: a confirmatory series. AB - INTRODUCTION: MiRNAs are small endogenous non-coding RNAs implicated with gene expression regulation. Changes in miRNA levels have been reported in thyroid cancer. Fine-needle aspiration cytology (FNAC) is the most reliable tool for differential diagnosis of thyroid nodules. METHODS: We have analyzed 174 FNAC from 168 patients with thyroid nodules for expression levels of 11 miRNAs (miRNA197; -187; -181b-3p; -181b-5p; -224; -181a; 146b; -221; -222; -155 and miRNA183) known to be up-regulated in cancer tissues compared to benign lesions. Expression of miRNAs was analyzed in FNA samples calculating the fold change of miRNA expression relative to normal thyroid tissue after normalization to an endogenous control. RESULTS: In FNAC, miRNA expression was confirmed to be higher in malignant or suspicious for malignancy nodules compared to benign, only for miRNA146b, -222 and -221 (fold change expression >= 5). CONCLUSION: In this study, we confirmed that a limited set of miRNAs can be used for the differential diagnosis of thyroid nodules. PMID- 29574527 TI - Treatment of Allergic Rhinitis as a Strategy for Preventing Asthma. AB - PURPOSE OF REVIEW: To evaluate the impact of allergic rhinitis (AR) on the development of asthma and to update readers on recent literature suggesting that early treatment of allergic subjects with immunotherapy may prevent asthma onset. RECENT FINDINGS: AR is frequently associated with asthma, leading to the concept that these two conditions are different aspects of the same disease. There is increasing evidence that AR precedes the onset of asthmatic symptoms and current treatment strategies are beneficial in symptom control with no impact prevention. There is limited knowledge about the risk factors responsible for the progression of AR to asthma, though recent data supports the notion that it is possible to prevent asthma onset by allergen immunotherapy. Despite significant advances in specific immunotherapy (SIT) therapy strengthening its efficacy in AR and possible prevention of progression to asthma, the adoption of this therapeutic strategy is still restricted in comparison to therapies directed towards treatment of AR symptoms. Unlike corticosteroids and other symptomatic therapies, the benefit of SIT treatment in allergic individuals has been shown to prevent the development of allergic conditions. Hence, large well-conducted randomized clinical trials with long-term efficacy of SIT are required to confirm or refute the concept that SIT may abrogate the progression of AR to asthma in patients. PMID- 29574530 TI - Cutaneous metastases of infantile choriocarcinoma can mimic infantile hemangioma both clinically and radiographically. AB - Infantile metastatic choriocarcinoma is a rare tumor of placental origin that can be observed with or without maternal metastases. A single cutaneous mass may be the only clinically observed sign. Reports of imaging findings are scarce given the extreme rarity of the tumor, and the disease can be rapidly fatal in the absence of prompt diagnosis. In order to promote timely consideration for this malignancy as a differential consideration in the approach to skin lesions in infancy, we present the findings of this neoplasm in an infant. While imaging and clinical characteristics similar to infantile hemangioma were demonstrated at presentation, biopsy and further radiologic investigation revealed multifocal metastatic choriocarcinoma. This case also highlights important differences between these entities, as the T2 hyperintensity and contrast enhancement observed with this choriocarcinoma were predominantly peripheral in location. PMID- 29574529 TI - Predictors of fat-free mass loss 1 year after laparoscopic sleeve gastrectomy. AB - PURPOSE: Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric surgery interventions because of its safety and efficacy. Nevertheless, concerns have been raised on its detrimental effect on patient nutritional state that can ultimately lead to the loss of fat-free mass (FFM). There is interest in identifying predictors for the early identification of patients at risk of this highly unwanted adverse because they could benefit of nutritional preventive interventions. Therefore, we investigated whether anthropometric parameters, body composition or resting energy expenditure (REE) measured before surgery could predict FFM loss 1 year after LSG. METHODS: Study design was retrospective observational. We retrieved data on body weight, BMI, body composition and REE before and 1 year after LSG from the medical files of 36 patients operated on by LSG at our institutions. Simple regression, the Oldham's method and multilevel analysis were used to identify predictors of FFM loss. RESULTS: Averaged percentage FFM loss 1 year after LSG was 17.0 +/- 7.7% with significant differences between sexes (20.8 +/- 6.6 in males and 12.2 +/- 6.1% in females, p < 0.001). FFM loss was strongly predicted by pre-surgery FFM and this effect persisted also after correcting for the contribution of sex. CONCLUSIONS: High FFM values before surgery predict a more severe FFM loss after LSG. This factor could also account for the higher FFM loss in men than in women. Our finding could help in the early identification of patient requiring a nutritional support after LSG. PMID- 29574531 TI - Trauma, Discrimination, and Psychological Distress Across Vietnamese Refugees and Immigrants: A Life Course Perspective. AB - Vietnamese Americans are a heterogeneous group with varied migration histories. The life course perspective (LCP) suggests that different migration histories (immigrant vs. refugee) may affect their psychological health. Using Vietnamese refugee (n = 291) and immigrant (n = 211) subsamples from the National Latino and Asian American Study, selected LCP factors relevant to foreign-born Vietnamese were examined for their associations with psychological distress. Two separate regressions were conducted to examine differential factors across the subgroups. Results showed that sex, age at immigration, and pre- and post-migration traumas were significant factors for refugees. Among immigrants, only racial discrimination was significant factor. The results suggest that applying LCP among Vietnamese Americans helps to discern factors associated with their psychological distress outcomes depending on their initial immigration status. The results also indicate that healthcare professionals should consider the migration background of foreign-born Vietnamese in screening for potential psychological issues, particularly around their trauma history and discriminatory experiences. PMID- 29574532 TI - An Examination of Peer-Delivered Parenting Skills Programs Across New York State. AB - Peers are an important adjunct to the public mental health service system, and are being increasingly utilized across the country as a cost-effective solution to workforce shortages. Despite the tremendous growth of peer-delivered support over the past two decades, it has only been within the past few years that peer programs have been the subject of empirical inquiry. The purpose of this study was to examine the prevalence and characteristics of peer-delivered parenting programs across the New York State public mental health service system. We surveyed 46 family peer organizations across New York State regarding their delivery of structured peer-delivered parenting programs. Thirty-four (76%) completed the questionnaire, and of them, 18 (53%) delivered a parenting program. Subsequent interviews with seven of the 18 organizations revealed peer organizations had been delivering eight unique parenting programs for upwards of two decades. Additionally, organizations offered multiple supports to families to participate. Training, supervision, and issues around fidelity are discussed, as well as the implications of this study for states utilizing a peer workforce.

PMID- 29574534 TI - To die or not to die: death signaling in nonalcoholic fatty liver disease. AB - Non-alcoholic fatty liver disease (NAFLD) is an emerging liver disease worldwide. In subset of patients, NAFLD progresses to its advanced form, nonalcoholic steatohepatitis (NASH), which is accompanied with inflammation and fibrosis. Saturated free fatty acid-induced hepatocyte apoptosis is a feature of NASH. Death signaling in NASH does not always result in apoptosis, but can alternatively lead to the survival of cells presenting signs of pro-inflammatory and pro-fibrotic signals. With the current lack of established treatments for NASH, it is important to understand the molecular mechanisms responsible for disease development and progression. This review focuses on the latest findings in hepatocyte death signaling and discusses possible targets for intervention, including caspases, death receptor and c-Jun N-terminal kinase 1 signaling, oxidative stress, and endoplasmic reticulum stress, as well as epigenomic factors. PMID- 29574535 TI - Epigenetics of Skeletal Diseases. AB - PURPOSE OF REVIEW: Epigenetic mechanisms modify gene activity in a stable manner without altering DNA sequence. They participate in the adaptation to the environment, as well as in the pathogenesis of common complex disorders. We provide an overview of the role of epigenetic mechanisms in bone biology and pathology. RECENT FINDINGS: Extensive evidence supports the involvement of epigenetic mechanisms (DNA methylation, post-translational modifications of histone tails, and non-coding RNAs) in the differentiation of bone cells and mechanotransduction. A variety of epigenetic abnormalities have been described in patients with osteoporosis, osteoarthritis, and skeletal cancers, but their actual pathogenetic roles are still unclear. A few drugs targeting epigenetic marks have been approved for neoplastic disorders, and many more are being actively investigated. Advances in the field of epigenetics underscore the complex interactions between genetic and environmental factors as determinants of osteoporosis and other common disorders. Likewise, they help to explain the mechanisms by which prenatal and post-natal external factors, from nutrition to psychological stress, impact our body and influence the risk of later disease. PMID- 29574536 TI - Does Maternal Exposure to Secondhand Tobacco Smoke During Pregnancy Increase the Risk for Preterm or Small-for-Gestational Age Birth? AB - Introduction While associations between active smoking and various adverse birth outcomes (ABOs) have been reported in the literature, less is known about the impact of secondhand smoke (SHS) on many pregnancy outcomes. Methods We examined the relationship between maternal exposure to SHS during pregnancy and preterm (< 37 weeks gestation) and small-for-gestational age (SGA; assessed using sex-, race/ethnic-, and parity-specific growth curves) singleton births using non smoking controls from the National Birth Defects Prevention Study (1997-2011). Multivariable logistic regression models for household, workplace/school, and combined SHS exposure-controlled for maternal education, race/ethnicity, pre pregnancy body mass index, and high blood pressure-were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Interaction was assessed for maternal folic acid supplementation, alcohol use, age at delivery, and infant sex. Results Infants of 8855 mothers were examined in the preterm birth analysis with 666 (7.5%) categorized as preterm, 574 moderately preterm (32-36 weeks), and 92 very preterm (< 32 weeks). For the SGA analysis, infants of 8684 mothers were examined with 670 (7.7%) categorized as SGA. The aORs for mothers reporting both household and workplace/school SHS were elevated for preterm (aOR 1.99; 95% CI 1.13-3.50) and moderately preterm birth (32-36 weeks) (aOR 2.17; 95% CI 1.22 3.88). No results for the SGA analysis achieved significance, nor was evidence of interaction evident. Conclusion The findings suggest an association between SHS from multiple exposure sources and preterm birth, but no evidence for association with SGA births. Continued study of SHS and ABOs is needed to best inform public health prevention programs.

PMID- 29574539 TI - Cervical Cancer Patients' Willingness and Ability to Serve as Health Care Educators to Advocate for Human Papillomavirus Vaccine Uptake. AB - Human papillomavirus (HPV) causes nearly all cervical cancer. Only half of females and less than half of males receive the recommended HPV vaccine dose. This study explores whether cervical cancer patients may serve as health advocates to adolescents and their parents in encouraging the uptake of the HPV vaccine. The study targeted an opportunity sample of women seen in the gynecology oncology clinic with a diagnosis of cervical cancer. During interviews, patients were asked about the following: provider conversations regarding cervical cancer, knowledge of HPV and the vaccine, discussions with family or friends about the causes or prevention of cervical cancer, and whether they would be willing to talk with others about the HPV vaccine. Twenty-three interviews were conducted in 2016-2017. Patients ranged from 28 to 61 years of age. Four team members developed a coding list, then used these themes to code the interviews. Six themes resulted from the analysis of the transcripts: (1) Expressions of fears, questioning effectiveness of vaccine; (2) Low level of health literacy; (3) Acquiring health information from television, internet; (4) Provider conversations (with patients regarding HPV and the vaccine); (5) Patient stigma surrounding cervical cancer; (6) Patients' willingness to serve as a health care educator. While cervical cancer patients overall expressed a willingness to serve as health care educators, barriers remain. Low health literacy and a lack of understanding of the causes of cervical cancer persist. These issues will need to be addressed in order for cervical cancer patients to be effective advocates. PMID- 29574538 TI - Identifying Factors Underlying the Decision for Sickle Cell Carrier Screening Among African Americans Within Middle Reproductive Age. AB - Guidelines recommend that African Americans know their sickle cell trait status to inform reproductive health decisions. Few studies have applied a behavioral theory to identify factors associated with sickle cell trait screening to inform intervention targets to increase this behavior. We applied a Sickle Cell Trait Screening Framework to identify factors associated with African Americans' intention to ask for sickle cell trait screening. Participants (N = 300), ages 18 to 35, completed a cross-sectional survey. A three-step sequential ordinary least squares regression analysis identified factors influencing intention. Results indicated socio-demographic factors (age, education), knowledge and fear beliefs (screening knowledge, perceived threat), and reasoned action approach (RAA) constructs were associated with intention. RAA constructs influenced intention over knowledge and fear beliefs with an increase in R2 of .468. Perceived behavioral control was more predictive of intention (beta = .576, p < .001). Attitude and perceived norm also had significant weights (beta = .325 and beta = .192, both p < .001, respectively). Findings from this study can inform strategies (e.g., eliminating costs associated with screening, reducing fear of painful tests) to increase sickle cell trait screening among African Americans. Ultimately, more sickle cell carriers will become aware of their trait status and be able to make informed reproductive health decisions. PMID- 29574540 TI - Supporting Latina Breast Health with Community-based Navigation. AB - Latina women continue to face disproportionate breast cancer risk and well documented breast health care barriers in Philadelphia. In response to breast health needs among Latinas in Philadelphia, a health-focused community-based organization, in partnership with a network of social and health service providers, began offering community-based navigation in 2005. Later, through funding from a federal agency, the organization launched the Naveguemos con Salud (NCS) Breast Health Partnership Project from 2010 to 2013. NCS offered breast health awareness and education to a broad audience of Latinas in Philadelphia and community-based navigation services to all interested in accessing a clinical breast exam (CBE) and/or mammogram. A 2017 survey revisited breast health needs among the same core population to inform next steps. Here, we explore how findings and lessons learned from a past program and an assessment of current needs can inform future community-clinical linkage and community-based navigation to improve access to breast cancer screening and a continuum of care for Latinas. PMID- 29574541 TI - Speech Therapy as Treatment for Supragastric Belching. AB - The purpose of this study was to describe a newly developed speech therapy program as an innovating therapeutic approach and to assess the results of this intervention in patients with supragastric belching. This is a retrospective analysis of prospectively gathered data from 73 patients with supragastric belching who were treated with speech therapy between 2007 and 2017. Of these, 48 were included for evaluation of therapy. Thirty patients had supragastric belching proven by 24-h impedance measurements. Eighteen patients were diagnosed by an experienced speech language pathologist as having supragastric belching according to precise criteria. Speech therapy consists of explanation, creating awareness of esophageal air influx and exercises to discontinue the supragastric belching mechanism. Therapy effect was measured by comparing visual analogue scale (VAS) scores on belching and related symptoms. The median symptom duration at the start of therapy was 2 years. Supragastric belching symptoms decreased significantly with a total median VAS score of 406 (291-463) prior to treatment and a median VAS score of 125 (17-197) following treatment. Forty patients (83%) had a sufficient to major result with a median therapy duration of 3 months and ten sessions. Speech therapy was an effective treatment in the majority of patients with supragastric belching. PMID- 29574542 TI - Factors Associated with Assignment of Therapeutic Homework in a Large Public Children's Mental Health System. AB - Therapeutic homework is a fundamental skill-building component of the majority of evidence-based therapies and is associated with better treatment outcomes. However, it is rarely utilized in public mental health settings. To determine barriers to homework use and identify predictors of clinicians' assignment of homework, an online survey was administered to 267 clinicians in a large diverse public mental health system. Clinicians who were younger, licensed, whose supervisors asked about homework and whose clients completed their homework more frequently were predictors of greater homework utilization. The survey results are discussed and a novel idea to increase the use of homework is introduced. PMID- 29574543 TI - Examining Mechanisms and Moderators of the Relationship Between Discriminatory Health Care Encounters and Attempted Suicide Among U.S. Transgender Help-Seekers. AB - This study examined how experiences of service denial and discrimination in three health care settings-doctors' offices, emergency rooms, and mental health clinics might contribute to attempted suicide among transgender adults. Mechanisms of this relationship were examined, including treatment receipt and the use of substances to cope with mistreatment. Perceived emotional social support was also tested as a potential protective factor against the deleterious effects of service denial and discrimination on treatment receipt, substance use, and attempted suicide. The analysis included 4190 respondents from the National Transgender Discrimination Survey. Structural equation modeling was employed to test hypothesized relationships. Being denied a greater number of services and discriminated against in more settings were associated with lower levels of treatment receipt. Service denial was also correlated with increased rates of coping-motivated substance use and elevated rates of attempted suicide. Treatment receipt mediated the relationships between service denial/discrimination and substance use. Substance use mediated the relationship between treatment receipt and attempted suicide. Higher levels of support were protective to treatment receipt when denied services in one setting, but no longer retained protective effects when denied in two or three settings. Results have critical implications for service access and delivery and policies that protect transgender help seekers in the health care system. PMID- 29574544 TI - Preservation of renal function in chronic diabetes by enhancing glomerular glucose metabolism. AB - Diabetic nephropathy (DN) affects approximately 30-40% of patients with type 1 (T1DM) and type 2 diabetes (T2DM). It is a major cause of end-stage renal disease (ESRD) for the developed world. Hyperglycemia and genetics are major causal factors for the initiation and progression of DN. Multiple abnormalities in glucose and mitochondrial metabolism induced by diabetes likely contribute to the severity of DN. Recent clinical studies in people with extreme duration of T1DM (> 50 years, Joslin Medalist Study) have supported the importance of endogenous protective factors to neutralize the toxic effects of hyperglycemia on renal and other vascular tissues. Using renal glomeruli from these patients (namely Medalists) with and without DN, we have shown the importance of increased glycolytic flux in decreasing the accumulation of glucose toxic metabolites, improving mitochondrial function, survival of glomerular podocytes, and reducing glomerular pathology. Activation of a key glycolytic enzyme, pyruvate kinase M2 (PKM2), resulted in the normalization of renal hemodynamics and mitochondrial and glomerular dysfunction, leading to the mitigation of glomerular pathologies in several mouse models of DN. PMID- 29574545 TI - Central sensitization is a risk factor for wound complications after primary total knee arthroplasty. AB - PURPOSE: Postoperative wound complication is a significant risk factor for subsequent deep periprosthetic joint infection after total knee arthroplasty (TKA). Central sensitization is an abnormal enhancement of pain mechanism involving the central nervous system. Although psychological disorder is widely considered as a risk factor, the relationship between central sensitization and wound complication is currently unclear. Therefore, the purpose of this study was to investigate whether central sensitization was associated with high wound complication rate after primary TKA. MATERIALS AND METHODS: Between January and June 2016, 161 patients undergoing unilateral TKA were prospectively divided into two groups based on central sensitization inventory score of 40 points after excluding cases with known risk factors such as physical comorbidities, health related behaviors, and psychological disorders. Group 1 consisted of 112 patients (112 knees) whose central sensitization inventory score was < 40 points and group 2 consisted of 49 patients (49 knees) whose central sensitization inventory score was >= 40 points. Wound complications were defined as wound dehiscence, suture granuloma, prolonged wound oozing after postoperative day 5, significant hematoma formation, or surgical site infection recorded during the initial 90-day postoperative period. Demographic data, visual analog scale (VAS), central sensitization inventory score, and wound complications were compared between the two groups. RESULTS: Wound complications developed in 3 (2.7%) knees in group 1 and 14 (28.6%) knees in group 2 (p < 0.001). Multivariate logistic regression analysis showed that the odds of postoperative wound complications were increased 15.7 times in patients with central sensitization inventory score >= 40 (95% CI 4.1-60.0, p < 0.001). CONCLUSION: Central sensitization is a risk factor for the development of postoperative wound complication after primary TKA. LEVEL OF EVIDENCE: II. PMID- 29574546 TI - Graft bending angle affects allograft tendon maturity early after anterior cruciate ligament reconstruction. AB - PURPOSE: The aim of this study was to clarify the association of the anterior cruciate ligament (ACL) graft bending angle and graft maturity of autograft and allograft tendons using high-resolution MRI. METHODS: Patients with unilateral ACL reconstruction were invited to participate in this study, and they were examined using a 3.0-T MRI scan at 3, 6 and 12 months after the operation. Anatomic single-bundle ACL reconstruction was performed on 48 patients using the trans-portal technique, including 28 with autograft hamstring tendons and 20 with allograft tendons. To evaluate graft healing, the signal/noise quotient (SNQ) was measured in four regions of interest (ROIs) of the femoral tunnel, proximal, midsubstance and distal ACL grafts. The graft bending angle was defined as the angle between the femoral bone tunnel and the line connecting the femoral and tibial tunnel apertures. Graft SNQ and graft bending angle were assessed at 3, 6 and 12 months postoperatively, and the association between SNQ and the average graft bending angle was analyzed. RESULTS: Generally, the mean graft bending angle of this cohort increased gradually with time. The SNQ value of each graft region increased from 3 to 6 months and then decreased from 6 to 12 months. In the whole cohort, the graft bending angle had a significant positive association with graft SNQ in the femoral tunnel or proximal site. In the allograft subgroup, the graft bending angle had a significant positive association with the graft SNQ in the femoral tunnel or proximal site at 6 months after surgery, while there was no association between the graft bending angle and SNQ at 12 months. In the autograft subgroup, the graft bending angle had a significant positive association with graft SNQ in the femoral tunnel or proximal site at 12 months after surgery. CONCLUSION: Generally, the graft bending angle was correlated with a high signal intensity of the proximal graft in the early postoperative period for allograft tendons and in the late postoperative period for allograft tendons. This suggests that the biomechanical effect from the graft bending angle on graft healing may be different for allografts and autografts after ACL reconstruction. LEVEL OF EVIDENCE: III. PMID- 29574547 TI - Hip capsular thickness correlates with range of motion limitations in femoroacetabular impingement. AB - PURPOSE: Femoroacetabular impingement (FAI) is a clinical entity of the hip causing derangements in range of motion, pain, gait, and function. Computer assisted modeling and clinical studies suggest that patients with FAI have increased capsular thickness compared to those without.A retrospective chart review was performed to assess relationships between capsular thickness, hip range of motion, and demographic factors in patients with FAI. METHODS: Local Research Ethics Board approval was obtained to extract electronic medical records for 188 patients at a single institution who had undergone hip arthroscopy. Procedures were performed from 2009 to 2017 by a single, fellowship-trained, board-certified sports medicine orthopaedic surgeon. Inclusion criteria were preoperative hip range of motion testing, positive clinical impingement testing, and magnetic resonance imaging (MRI) of the affected hip. Patient demographics, hip range of motion, and time to surgery were recorded. MRIs were reviewed by a board-certified musculoskeletal radiologist blinded to clinical data. Maximum thickness of the anterior hip capsule was measured in axial, axial oblique, and sagittal oblique sequences. Anterior capsular thickness was also measured at the level of the femoral head-neck junction in axial sequences (axial midline). RESULTS: Axial midline capsular thickness was negatively correlated with hip flexion (r = - 0.196, p = 0.0042) and internal rotation (r = - 0.143, p = 0.0278). Significant differences were seen between genders in axial midline thickness (5.3 +/- 1.4 mm males/4.8 +/- 1.3 mm females, p = 0.0079), flexion (113 degrees +/- 18 degrees males/120 degrees +/- 17 degrees females, p = 0.0029), and internal rotation (23 degrees +/- 13 degrees males/29 degrees +/- 12 degrees females, p = 0.0155). Significant differences also existed between side affected in flexion (116 degrees +/- 17 degrees right/119 degrees +/- 17 degrees left, p = 0.0396) and internal rotation (26 degrees +/- 12 degrees right/29 degrees +/- 13 degrees left, p = 0.0029). Positive correlation was observed between axial oblique capsular thickness and flexion (r = 0.2345) (p = 0.0229). CONCLUSIONS: Increased anterior hip capsular thickness at the femoral head-neck correlates with limitations in hip range of motion in FAI. The strength of this relationship may be affected between pathologies, genders, and affected side. Pathologic thickening of the hip capsule may contribute to restricted hip mobility on clinical examination, and elucidation of this relationship may provide guidance into capsular management during hip arthroscopy.

PMID- 29574548 TI - Low rates of patients meeting return to sport criteria 9 months after anterior cruciate ligament reconstruction: a prospective longitudinal study. AB - PURPOSE: The purpose of the current prospective study was to assess the changes over time in patients tested at 6 months and 9 months after anterior cruciate ligament reconstruction (ACLR) with a return to sport (RTS) test battery. It was hypothesized that more patients passed RTS criteria at 9 months compared to 6 months. METHODS: Sixty-two ACLR patients performed a test battery at an average of 6.5 +/- 0.7 and 9.5 +/- 0.9 months after ACLR. All patients underwent a standardized rehabilitation protocol. The test battery consisted of the following tests: a jump-landing task assessed with the Landing Error Scoring System (LESS), three single-leg hop tasks (single-leg hop test, triple-leg hop test, side hop test), isokinetic quadriceps and hamstring strength at 60, 180 and 300 degrees /s and two questionnaires (IKDC and ACL-RSI). Cut off criteria were set as Limb Symmetry Index (LSI) > 90% (for isokinetic strength and for single-leg hop tasks), LESS < 5, IKDC score within 15th percentage of healthy subjects and ACL RSI > 56 respectively. RESULTS: At 6 months, two patients (3.2%) passed all criteria. At 9 months, seven patients (11.3%) passed all criteria. Patients improved in all RTS criteria over time except for the IKDC score. Twenty-nine patients (46.8%) did not pass the strength criterion at 60 degrees /s at 9 months after ACLR. CONCLUSIONS: The percentages of patients passing all RTS criteria were low at both 6 and 9 months after ACLR. Quadriceps strength revealed persistent deficits and the lack of improvement in the IKDC score questionnaires shows insufficient self-reported knee function for RTS. LEVEL OF EVIDENCE: III.

AB - PURPOSE: The benefits of simultaneous bilateral total knee arthroplasty (SBTKR) include reduced hospital costs, single anaesthetic exposure and in many cases is also the patient's preference. Despite these potential benefits, risk-adversity with respect to assumed complications and mortality make it difficult for the orthopaedic surgeon and patient to make an informed decision. This study aimed to address the inconsistencies and lack of consensus in previous literature regarding the short-term complications and clinical safety of SBTKR in patients with end-stage knee osteoarthritis (OA). METHODS: A cohort of 950 knees (475 patients) undergoing surgery between 2008 and 2013 was extracted from a prospectively collected clinical database and retrospectively linked to the Australian Joint Replacement Registry and hospital records. Patients underwent sequential SBTKR by their treating surgeon under one anaesthetic. Basic demographic data and outcome data including complications and mortality were collected. All data were analyzed using descriptive statistics only. RESULTS: A total of 413 patients and 826 knees were included. The average age of the cohort was 70 years with range between 46 and 88 years. 50% of patients were female. The overall mortality rate during the study follow-up period was 1.9%, with an average time to death postoperatively of 23.8 months. There were no cases of acute postoperative mortality (< 6 weeks). Medical complication rates were low. CONCLUSIONS: In contrast to the higher mortality and complication rates suggested in previous literature, this study has demonstrated that SBTKR is safe, with low mortality and complication rates under the current surgical protocol.

AB - PURPOSE OF REVIEW: Real-time 3-dimensional (3-D) imaging of cardiovascular injury and regeneration remains challenging. We introduced a multi-scale imaging strategy that uses light-sheet illumination to enable applications of cardiovascular injury and repair in models ranging from zebrafish to rodent hearts. RECENT FINDINGS: Light-sheet imaging enables rapid data acquisition with high spatiotemporal resolution and with minimal photo-bleaching or photo toxicity. We demonstrated the capacity of this novel light-sheet approach for scanning a region of interest with specific fluorescence contrast, thereby providing axial and temporal resolution at the cellular level without stitching image columns or pivoting illumination beams during one-time imaging. This cutting-edge imaging technique allows for elucidating the differentiation of stem cells in cardiac regeneration, providing an entry point to discover novel micro circulation phenomenon with clinical significance for injury and repair. These findings demonstrate the multi-scale applications of this novel light-sheet imaging strategy to advance research in cardiovascular development and regeneration. PMID- 29574552 TI - Production systems of Japanese quail (Coturnix coturnix japonica) in the urban communities of southwestern Nigeria. AB - The study was conducted to examine the management practices and constraints associated with quail production in southwestern Nigeria. Data were collected through a survey of 113 quail bird farmers selected by multi-stage sampling technique from three states of southwestern Nigeria. Data were analyzed mainly by descriptive statistics with values compared across states using relevant statistics at certain instances. The results show that quail farming is a relatively new enterprise with farmers' average year of experience estimated as 4.52 years. Production was predominantly for the sale of eggs and table birds (46.90%). They were reared under intensive system (87.61%) and in deep litters (53.10%). Birds were commonly reared with chicken (71.03% of the farmers). Foundation stocks were sourced from commercial farms (33.63%) and hatcheries (25.66%), while birds were fed on compounded feed by 73.45% of the farmers in the morning and evening (55.75%). Veterinary support services were sought occasionally by 76.99% of the farmers while 55.7 and 40.71% of the farmers vaccinated and dewormed their birds, respectively. Disease incidence was generally low across the states with incidence in 13.27% of the farms with associated mortality of 2.05%. Quail eggs and birds were predominantly sold at farm gate (81.42%) at average prices of N632.94 per crate and N584.09 per bird respectively. Notable constraints were inadequate technical knowledge on feed formulation, difficulty in meat processing and marketing, which need to be addressed for upscaling the technology. PMID- 29574553 TI - Time of feeding and predictability of dry matter and water intake of grasscutters fed on grass and supplements containing varying levels of dietary fiber. AB - The study evaluated the feeding behavior of growing male grasscutters (Thryonomys swinderianus) fed freshly cut Panicum maximum, supplemented with pelletized concentrates containing varying levels of dietary fiber. In a two-stage 4 * 4 Latin square arrangement, the relationships between water and dry matter intakes as influenced by dietary characteristics were investigated by offering supplements either at 09:00 h (morning) during the first stage or at 17:00 h (evening) during the second. Each test period lasted for 14 days with a 1-week rest period between changeovers. Time of feeding significantly (P < 0.05) affected total dry matter intake (DMI) and intake of the supplements, with the total DMI increasing by 21% when the diets were offered in the evening relative to when offered in the morning. Regression analyses showed significant (P < 0.05) correlations between dry matter (DM) and water intakes against some dietary characteristics. The current study has shown that crude fiber (CF) inclusion of up to 14% in pelletized supplements for growing grasscutters consuming a basal diet with CF up to 31% may not affect feed and water intake, as well as acceptability of the feed. However, feeding such supplements in the evening could stimulate higher feed intake. Also, dietary DM better predicted DMI compared to the other dietary characteristics. PMID- 29574554 TI - Chimpanzees prioritise social information over pre-existing behaviours in a group context but not in dyads. AB - How animal communities arrive at homogeneous behavioural preferences is a central question for studies of cultural evolution. Here, we investigated whether chimpanzees (Pan troglodytes) would relinquish a pre-existing behaviour to adopt an alternative demonstrated by an overwhelming majority of group mates; in other words, whether chimpanzees behave in a conformist manner. In each of five groups of chimpanzees (N = 37), one individual was trained on one method of opening a two-action puzzle box to obtain food, while the remaining individuals learned the alternative method. Over 5 h of open access to the apparatus in a group context, it was found that 4/5 'minority' individuals explored the majority method and three of these used this new method in the majority of trials. Those that switched did so after observing only a small subset of their group, thereby not matching conventional definitions of conformity. In a further 'Dyad' condition, six pairs of chimpanzees were trained on alternative methods and then given access to the task together. Only one of these individuals ever switched method. The number of observations that individuals in the minority and Dyad individuals made of their untrained method was not found to influence whether or not they themselves switched to use it. In a final 'Asocial' condition, individuals (N = 10) did not receive social information and did not deviate from their first learned method. We argue that these results demonstrate an important influence of social context upon prioritisation of social information over pre-existing methods, which can result in group homogeneity of behaviour. PMID- 29574551 TI - The Dysfunction of the Cerebellum and Its Cerebellum-Reward-Sensorimotor Loops in Chronic Spontaneous Urticaria. AB - Chronic spontaneous urticaria (CSU) is a common itchy skin disease. Despite its prevalence, the neuropathology of CSU is uncertain. In this study, we explored resting state functional connectivity (rs-FC) changes in CSU, as well as how the symptom changes following intervention can modulate rs-FC. Forty patients and 40 healthy controls (HCs) were recruited. Following an intervention, 32 patients participated in a second scan approximately 6 weeks after the first scan. Compared with healthy controls, CSU subjects exhibited higher regional homogeneity (ReHo) values in the cerebellum, which were positively associated with urticaria activity scores over 7 days (UAS7) at baseline. After an intervention accompanied with clinical improvement, we found that ReHo values decreased at the cerebellum and increased at the bilateral primary somatosensory cortex (SI)/primary motor cortex (MI)/supplementary motor area (SMA). Using the cerebellum as a seed, CSU subjects exhibited increased rs-FC with reward regions when compared with HCs and exhibited decreased rs-FC at the right orbitofrontal cortex and right sensorimotor region following the intervention. The improvement rate values were positively associated with reduced rs-FC values in the two regions. Using the cluster of SI/MI/SMA as a seed, CSU patients exhibited decreased rs-FC with the left putamen, caudate, accumbens, and thalamus following the intervention. These results demonstrate the altered cerebellar activity and cerebellum-reward-sensorimotor loops in CSU. PMID- 29574555 TI - Paediatric lateral condyle fractures: a systematic review. AB - INTRODUCTION: Lateral condyle fractures of the humerus are common paediatric fractures. However, no conclusive statement has been made about their risk of complications, the management and epidemiology. MATERIALS AND METHODS: A systematic review was conducted according to PRISMA guidelines. All studies with paediatric lateral condyle fracture were included, with 2440 children. RESULTS: Most fractures had union, with 0.9% delayed union, 1.6% non-union and 1.5% malunion. Complications included valgus deformities (6.1%), varus deformities (7.8%), flexion loss (9.7%), extension loss (11.5%), prominent lateral condyle (27.3%), fishtail deformity (14.3%), avascular necrosis (1.7%), premature epiphyseal closure (5.4%) and neurological deficits (10.6%). Risk factors of complications include concomitant ipsilateral upper limb fractures, classification by Milch or Jakob, fracture displacement, fixation device, and inappropriate diagnosis and management. CONCLUSIONS: It is recommended for fractures that are non-displaced on all radiographic views to be managed conservatively, while displaced fractures of > 2 mm requires surgical intervention. Minimally displaced fractures could be treated conservatively, though follow-up is recommended to detect displacement. Radiographs are also recommended at 1-week follow-up, with serial radiographs having no clinical significance. Kirschner wires or lag screws could be employed, and it is recommended that the Kirschner wires be left exposed and removed when there is clinical and radiographic evidence of fracture consolidation, typically at the 6 week interval. These fractures need close follow-up. PMID- 29574556 TI - Fatigue, as measured using the Modified Fatigue Impact Scale, is a predictor of processing speed improvement induced by exercise in patients with multiple sclerosis: data from a randomized controlled trial. AB - BACKGROUND: Few studies have evaluated the impact of physical activity (PA) on cognition and fatigue, and none have considered the effects of PA on the relationship between cognition and fatigue. OBJECTIVES: We evaluated the effect of PA in people with multiple sclerosis (pwMS) in a 6-month-long single-blind randomized controlled trial. We focused on the impact of exercise on cognition, fatigue, and the relationship between cognition and fatigue. METHODS: We recruited pwMS, who were then randomly assigned 1:1 to either a PA protocol group or a control group (CG). All patients underwent assessments using the Brief International Cognitive Assessment for Multiple Sclerosis including symbol digit modality test (SDMT), Berg Balance Scale (BBS), gait analysis, 6-Minute Walk Test, Timed Up and Go (TUG) test, and the Modified Fatigue Impact Scale (MFIS) at the beginning of the study (T0), at the end of the study (EOS) 24 weeks after T0, and at 24 weeks following the EOS (FU). RESULTS: A Wilcoxon test revealed a significant effect of exercise in the PA group, but not in the CG. Significant differences between T0 and EOS were found in the spatiotemporal parameters of gait, and performance on the SDMT, TUG, BBS, and MFIS. These differences were also present during the FU period. A regression model revealed that the baseline MFIS score predicted processing speed improvement (R2 = 0.65, p < 0.01), as the SDMT T score increased by 0.3 for each one-unit increase in the MFIS score at T0. CONCLUSION: PA affects multiple aspects of the pathology in pwMS. Patients with greater fatigue must not be discouraged from exercise, as they may greatly benefit from PA. Specifically, PA was shown to improve information processing speed. PMID- 29574558 TI - Defining the abdominal radiologist based on the current U.S. job market. AB - PURPOSE: The purpose of the study is to characterize current practice patterns of abdominal radiologists based on work descriptions within job postings on numerous national radiology specialty websites. METHODS: Job postings for either "abdominal" or "body" radiologists were searched weekly on five society websites (SAR, SCBT-MR, ARRS, ACR, RSNA) over a 1-year period. Postings were reviewed for various characteristics. RESULTS: Nine hundred and sixteen total ads for 341 unique abdominal radiologist positions were reviewed (34.6% academic, 64.2% private practice, 1.2% other). Postings occurred most commonly in March (12.3%) and least commonly in November (4.8%). States with most positions were Florida (27), California (26), and New York (24). Of postings delineating expectations of specific abdominal modalities, 67.4% mentioned MRI, 58.5% ultrasound, 41.1% fluoroscopy, 14.3% PET, and 54.0% interventions. Additional non-abdominal expectations included general radiology (28.7%), breast imaging (21.1%), and general nuclear medicine (9.7%). Additional skills included prostate MRI (7.0%), OBGYN ultrasound (5.0%), and CT colonoscopy (2.6%). 79.2% required an abdominal imaging fellowship (specifically a body MRI fellowship in 4.1%). CONCLUSION: By using job postings for abdominal radiologists, we have taken a practical approach to characterizing the current status of this subspecialty, reflecting recent job expectations and requirements. The large majority of positions required a body fellowship, and the positions commonly entailed a variety of skills beyond non invasive diagnostic abdominal imaging. Of note, expectations of considerable minorities of positions included abdominal interventions, general radiology, and breast imaging. These insights may guide the development of abdominal radiology fellowships and mini-fellowships, as well as assist radiologists entering or returning to the job market. PMID- 29574557 TI - miRNAs control HAM1 functions at the single-cell-layer level and are essential for normal embryogenesis in Arabidopsis. AB - KEY MESSAGE: miR171a controls HAM1 functions within the protodermal cells of the embryo, and these controls are essential for normal embryogenesis in Arabidopsis. Arabidopsis thaliana miR171a is known to bind to and cleave mRNAs of three HAIRY MERISTEM (HAM) genes that encode members of the GRAS family transcriptional regulators. The molecular functions of the HAM genes are still being elucidated in Arabidopsis. However, detailed expression patterns of miR171a and the effects of the failure of miR171a to suppress HAM genes were unknown till now. Here, we show the detailed expression patterns of miR171a and HAM1 using green fluorescent protein and confocal scanning microscopy. Our observations revealed that miR171a was expressed in the surface cell layer of the embryo and shoot apical meristem, and it controlled HAM1 functions. To determine the impact of the failure of miR171a to suppress of HAM1, we introduced seven synonymous mutations into the miR171a target site of the HAM1 gene (modified HAM1, mHAM1) and generated transgenic plants that had mHAM1 driven by HAM1 native promoter. The mHAM1 transgenic plants showed organogenic defects. These results indicate that the control of HAM1 functions at the single-cell-layer level by miR171a is essential for proper organ formation in Arabidopsis. PMID- 29574559 TI - How Do Storms Affect Asthma? AB - PURPOSE OF REVIEW: There are observations in various geographical areas that thunderstorms occurring during pollen seasons can induce severe asthma attacks in pollinosis patients. RECENT FINDINGS: An accredited hypothesis explaining the association between thunderstorms and asthma suggests that storms can concentrate pollen grains at ground level, which may then release allergenic particles of respirable size in the atmosphere after their imbibition of water and rupture by osmotic shock. During the first 20-30 min of a thunderstorm, patients affected by pollen allergy may inhale a high quantity of the allergenic material that is dispersed into the atmosphere as a bioaerosol of allergenic particles, which can induce asthmatic reactions, often severe. Subjects without asthma symptoms, but affected by seasonal rhinitis can also experience an asthma attack. A key message is that all subjects affected by pollen allergy should be alerted to the danger of being outdoors during a thunderstorm in the pollen season, as such events may be an important cause of severe asthma exacerbations. In light of these observations, it is useful to predict thunderstorms and thus minimize thunderstorm-related events. Patients with respiratory allergy induced by pollens and molds need to be informed about a correct therapeutic approach of bronchial asthma by inhalation, including the use of bronchodilators and inhaled corticosteroids. The purpose of this review is to focalize epidemiological, etiopathogenetic, and clinical aspects of thunderstorm-related asthma. PMID- 29574560 TI - In-house validation of a rapid and efficient procedure for simultaneous determination of ergot alkaloids and other mycotoxins in wheat and maize. AB - A fundamental step in addressing the global problem of mycotoxins is the development of highly sensitive, multi-class extraction and detection methods. This constitutes a field of research that has in recent years enjoyed a steady advance. Such methods, generally based on liquid chromatography coupled to mass spectrometry, are widely reported successfully detecting various mycotoxins in different food and feed samples. In this work, an innovative approach to multi class mycotoxin control is proposed, offering specific advantages: a broader inclusion of more mycotoxin classes, robust and thorough extraction for all target compounds despite their varied chemical properties, and determination of all analytes from a single injection. The method involved the extraction and quantification of the main mycotoxins produced by Aspergillus, Fusarium, and Penicillium fungi, as well as their reported derivatives, together with 12 other compounds most commonly produced by Claviceps purpurea. The popularly reported QuEChERS technique has been reduced to a simple "salting-out liquid-liquid extraction" (SO-LLE) to obtain the most efficient extraction of the aforementioned mycotoxin classes in a very short time. This is in particular extremely important in ensuring correct determination of individual ergot alkaloids, for which short and robust sample preparation as well as short analytical sequences were key for minimizing the epimerization during analysis. The analyses of wheat and maize samples were performed using ultra-high performance liquid chromatography coupled with tandem mass spectrometry. Matrix matched calibration curves were established and limits of quantification were below the maximum levels established by the EU regulation. The precision (repeatability and intermediate precision) was lower than 13% in all cases and recoveries ranged between 60 and 98% in maize and between 62 and 103% in wheat, fulfilling the current legislation. The method was applied to study the co occurrence of these mycotoxins in wheat (n = 13) and maize (n = 15) samples from six European countries. A successful quantification of 23 different mycotoxins, from all major classes, in 85% of wheat and 93% of maize samples was achieved. PMID- 29574561 TI - Critical assessment of digital PCR for the detection and quantification of genetically modified organisms. AB - The number of genetically modified organisms (GMOs) on the market is steadily increasing. Because of regulation of cultivation and trade of GMOs in several countries, there is pressure for their accurate detection and quantification. Today, DNA-based approaches are more popular for this purpose than protein-based methods, and real-time quantitative PCR (qPCR) is still the gold standard in GMO analytics. However, digital PCR (dPCR) offers several advantages over qPCR, making this new technique appealing also for GMO analysis. This critical review focuses on the use of dPCR for the purpose of GMO quantification and addresses parameters which are important for achieving accurate and reliable results, such as the quality and purity of DNA and reaction optimization. Three critical factors are explored and discussed in more depth: correct classification of partitions as positive, correctly determined partition volume, and dilution factor. This review could serve as a guide for all laboratories implementing dPCR. Most of the parameters discussed are applicable to fields other than purely GMO testing. Graphical abstract There are generally three different options for absolute quantification of genetically modified organisms (GMOs) using digital PCR: droplet- or chamber-based and droplets in chambers. All have in common the distribution of reaction mixture into several partitions, which are all subjected to PCR and scored at the end-point as positive or negative. Based on these results GMO content can be calculated. PMID- 29574563 TI - Change in Health Insurance Coverage After Liver Transplantation Can Be Associated with Worse Outcomes. AB - BACKGROUND: Health insurance coverage changes for many patients after liver transplantation, but the implications of this change on long-term outcomes are unclear. AIMS: To assess post-transplant patient and graft survival according to change in insurance coverage within 1 year of transplantation. METHODS: We queried the United Network for Organ Sharing for patients between ages 18-64 years undergoing liver transplantation in 2002-2016. Patients surviving > 1 year were categorized by insurance coverage at transplantation and the 1-year transplant anniversary. Multivariable Cox regression characterized the association between coverage pattern and long-term patient or graft survival. RESULTS: Among 34,487 patients in the analysis, insurance coverage patterns included continuous private coverage (58%), continuous public coverage (29%), private to public transition (8%) and public to private transition (4%). In multivariable analysis of patient survival, continuous public insurance (HR 1.29, CI 1.22, 1.37, p < 0.001), private to public transition (HR 1.17, CI 1.07, 1.28, p < 0.001), and public to private transition (HR 1.14, CI 1.00, 1.29, p = 0.044), were associated with greater mortality hazard, compared to continuous private coverage. After disaggregating public coverage by source, mortality hazard was highest for patients transitioning from private insurance to Medicaid (HR vs. continuous private coverage = 1.32; 95% CI 1.14, 1.52; p < 0.001). Similar differences by insurance category were found for death-censored graft failure. CONCLUSION: Post-transplant transition to public insurance coverage is associated with higher risk of adverse outcomes when compared to retaining private coverage. PMID- 29574565 TI - Atorvastatin decreases steroid production in H295R cells and in major endocrine tissues of male rats. AB - Obesity is increasing worldwide, and since obesity is associated with dyslipidemia, the consumption of cholesterol-lowering pharmaceuticals has increased. The aim of this study was therefore to study potential endocrine disrupting effects of one of the world's most frequently prescribed drugs, the cholesterol-lowering drug, atorvastatin (ATO) in vitro using the H295R steroidogenesis assay and in vivo using male Sprague-Dawley rats. We analyzed all major steroids in the mammalian steroidogenesis using liquid chromatography tandem mass spectrometry (LC-MS/MS). In vitro, ATO significantly decreased all steroids in the H295R steroidogenesis at concentrations close to human plasma Cmax values, with an IC50 value for testosterone of 0.093 +/- 0.033 uM. Additionally, we determined steroid hormone levels in testis, adrenals, brain and plasma from rats after 14 days of exposure to three therapeutically relevant doses of ATO and observed pronounced decreasing steroid levels in particular in testis and adrenals but also in brain and plasma. In testis, all major steroidogenic enzymes were up-regulated, indicating autocrine and/or paracrine compensation for the decrease in steroid production by this tissue. In adrenals, StAR and CYP11A1 gene expression were decreased, whereas little effects were observed in the brain. Furthermore, we analyzed plasma LH and ACTH levels to investigate feedback via the PT and HPA axes. No effects were observed on LH levels, indicating little compensation via the PT axis. In contrast, ACTH levels increased during ATO exposure, indicating that the HPA axis to some extend compensated for the decrease in adrenal steroid production. Overall, ATO exerted pronounced effects on steroid production both in vitro and in vivo at therapeutically relevant doses. This clearly demonstrates the high potency of ATO to affect steroid homeostasis during therapeutic treatment. Further clinical and epidemiological studies should be conducted to investigate the relevance of these observations in patients treated with cholesterol-lowering pharmaceuticals.

PMID- 29574562 TI - Severe Cutaneous Adverse Drug Reactions: Presentation, Risk Factors, and Management. AB - PURPOSE OF STUDY: Immune-mediated adverse drug reactions occur commonly in clinical practice and include mild, self-limited cutaneous eruptions, IgE mediated hypersensitivity, and severe cutaneous adverse drug reactions (SCAR). SCARs represent an uncommon but potentially life-threatening form of delayed T cell-mediated reaction. The spectrum of illness ranges from acute generalized exanthematous pustulosis (AGEP) to drug reaction with eosinophilia with systemic symptoms (DRESS), to the most severe form of illness, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). RECENT FINDINGS: There is emerging literature on the efficacy of cyclosporine in decreasing mortality in SJS/TEN. The purpose of our review is to discuss the typical presentations of these conditions, with a special focus on identifying the culprit medication. We review risk factors for developing SCAR, including HLA alleles strongly associated with drug hypersensitivity. We conclude by discussing current strategies for the management of these conditions. PMID- 29574567 TI - Two-port robotic hysterectomy: a novel approach. AB - The objective of the study was to demonstrate a novel technique for two-port robotic hysterectomy with a particular focus on the challenging portions of the procedure. The study is designed as a technical video, showing step-by-step a two port robotic hysterectomy approach (Canadian Task Force classification level III). IRB approval was not required for this study. The benefits of minimally invasive surgery for gynecological pathology have been clearly documented in multiple studies. Patients had fewer medical and surgical complications postoperatively, better cosmesis and quality of life. Most gynecological surgeons require 3-5 ports for the standard gynecological procedure. Even though the minimally invasive multiport system provides an excellent safety profile, multiple incisions are associated with a greater risk for morbidity including infection, pain, and hernia. In the past decade, various new methods have emerged to minimize the number of ports used in gynecological surgery. The interventions employed were a two-port robotic hysterectomy, using a camera port plus one robotic arm, with a focus on salpingectomy and cuff closure. We describe a transvaginal and a transabdominal approach for salpingectomy and a novel method for cuff closure. The transvaginal and transabdominal techniques for salpingectomy for two-port robotic-assisted hysterectomy provide excellent tension and exposure for a safe procedure without the need for an extra port. We also describe a transvaginal technique to place the vaginal cuff on tension during closure. With the necessary set of skills on a carefully chosen patient, two-port robotic-assisted total laparoscopic hysterectomy is a feasible procedure. PMID- 29574566 TI - Diagnostic performance of apparent diffusion coefficient parameters for glioma grading. AB - This study was to evaluate the diagnostic performance of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) parameters derived from diffusion tensor imaging in the differentiation between grade II and III gliomas. The records of 60 patients (30 women, 30 men; mean age, 45.4 years) suspected of having gliomas who underwent an ADC image-guided stereotactic biopsy were retrospectively reviewed. The values of FA and ADC were measured, and the sensitivity, specificity, accuracy and area under the curve (AUC) of those parameters were calculated based on the receiver operating characteristic curve analysis. A predictive diagnostic equation was also constructed and evaluated. Significant differences in minimum ADC values were found in the quantitative analysis between the grade III and II glioma groups. The sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), accuracy and AUC for identifying grade III and II gliomas at the optimum cut-off value of 0.895 * 10-3 mm2/s of minimum ADC were 81.0, 89.1, 77.3, 91.1, 86.6 and 0.87, respectively. The predictive diagnostic equation was superior to the single minimum ADC indicator with a sensitivity of 90.5%, a specificity of 84.8%, a PPV of 73.1%, an NPV of 95.1%, and an accuracy of 86.6%, respectively. The study provides evidence that minimum ADC values have a superior diagnostic performance in differentiating grade III and II gliomas, and the predictive diagnostic equation may be helpful in the differentiation. PMID- 29574568 TI - Diffuse large B cell lymphoma (DLBCL): bilateral vanishing tibiae. PMID- 29574569 TI - Internal biliary stenting in liver transplantation. AB - PURPOSE: Internal biliary stenting (IBS) was reported to decrease biliary complications after liver transplantation (LT) but data in literature is scarce. The aim of the present study was to evaluate our experience with end-to-end choledoco-choledocostomy during liver transplantation with special focus on the influence of IBS on patient and biliary outcomes. METHODS: Between 2009 and 2013, 175 patients underwent deceased donor LT with end-to-end choledoco-choledocostomy and were included in the study. Supra-papillary silastic stent was inserted in 67 patients (38%) with small-size (< 5 mm) bile ducts (recipient or donor). Endoscopic retrograde cholangiopancreatography (ERCP) was scheduled for IBS removal, 6 months after LT. Operative outcomes and survival of patients who received internal stenting (IBS group) were compared with those of patients who did not (no-IBS group). Risk factors for biliary anastomotic complications were identified. RESULTS: Ten patients died (6%) and 104 (59%) experienced postoperative complications. Five-year patient and graft survival rates were 77 and 74%, respectively. Biliary complications were recorded in 61 patients (35%) and were significantly decreased by IBS insertion (p = 0.0003). Anastomotic fistulas occurred in 23 patients (13%) and stenoses in 44 patients (25%). On multivariate analysis, high preoperative MELD scores (p = 0.02) and hepatic artery thrombosis (p < 0.0001) were predictors of fistula; absence of IBS was associated with both fistula (p = 0.014) and stricture (p = 0.003) formation. CONCLUSIONS: IBS insertion during LT decreases anastomotic complication. PMID- 29574571 TI - A bony defect of the sphenoid air sinus found in male cadaver: a case report. AB - The sphenoid sinus one of the posterior group of sinus, considered one of the most difficult sinuses due to its deep location in the skull. The interest in the understanding of the anatomy of the sphenoid sinus increased markedly during the last decades due to the development of endoscopic transsphenoidal approaches to the intracranial structures. The important anatomical relations of the sphenoid sinus make it one of the difficult and challenging structures for the surgeons. In this case report, we present one of the anatomical variations that was found during cadaveric dissection of the head. In this case we found abnormal bony defect in the lateral wall of the sinus, the defect closed just by the lining mucosa of the sinus and the dura from its intracranial side. A point may be of clinical importance to the related nearby structures. PMID- 29574570 TI - Identification and validation of genomic regions influencing kernel zinc and iron in maize. AB - KEY MESSAGE: Genome-wide association study (GWAS) on 923 maize lines and validation in bi-parental populations identified significant genomic regions for kernel-Zinc and-Iron in maize. Bio-fortification of maize with elevated Zinc (Zn) and Iron (Fe) holds considerable promise for alleviating under-nutrition among the world's poor. Bio-fortification through molecular breeding could be an economical strategy for developing nutritious maize, and hence in this study, we adopted GWAS to identify markers associated with high kernel-Zn and Fe in maize and subsequently validated marker-trait associations in independent bi-parental populations. For GWAS, we evaluated a diverse maize association mapping panel of 923 inbred lines across three environments and detected trait associations using high-density Single nucleotide polymorphism (SNPs) obtained through genotyping-by sequencing. Phenotyping trials of the GWAS panel showed high heritability and moderate correlation between kernel-Zn and Fe concentrations. GWAS revealed a total of 46 SNPs (Zn-20 and Fe-26) significantly associated (P <= 5.03 * 10-05) with kernel-Zn and Fe concentrations with some of these associated SNPs located within previously reported QTL intervals for these traits. Three double-haploid (DH) populations were developed using lines identified from the panel that were contrasting for these micronutrients. The DH populations were phenotyped at two environments and were used for validating significant SNPs (P <= 1 * 10-03) based on single marker QTL analysis. Based on this analysis, 11 (Zn) and 11 (Fe) SNPs were found to have significant effect on the trait variance (P <= 0.01, R2 >= 0.05) in at least one bi-parental population. These findings are being pursued in the kernel-Zn and Fe breeding program, and could hold great value in functional analysis and possible cloning of high-value genes for these traits in maize.

AB - INTRODUCTION: Treatment with finasteride 1 mg/day represents the therapy of choice for androgenetic alopecia (AGA). We investigated how Italian dermatologists approach use of finasteride for treatment of AGA and common side effects reported by patients. METHODS: A tablet-based survey was conducted from February 2017 to January 2018 in Italy to investigating use of 1 mg/day finasteride in the treatment of AGA. Approximately 1153 Italian dermatologists were surveyed about prescription frequency, therapy duration, treatment practices, and side effects eventually reported. RESULTS: Dermatologists considered treatment with 1 mg/day finasteride to be the most efficacious treatment for AGA, as reflecting by its long-term (5 years) prescription. Data on sexual side effects from our survey are in line with previous scientific evidence, especially regarding loss of libido, erectile dysfunction, and problems with ejaculation, but also in the psychological sphere and regarding physical impairments such as myalgia and loss of muscle tone. CONCLUSIONS: This is the first preliminary observational study on how Italian dermatologists approach use of finasteride to treat AGA. Although side effects have been reported, especially in the sexual sphere, lack of alternative treatments with the same efficacy leads dermatologists to prescribe 1 mg/day finasteride with a tendency to prolong therapy in the long term.

PMID- 29574575 TI - Dimethyl fumarate (DMF) vs. monoethyl fumarate (MEF) salts for the treatment of plaque psoriasis: a review of clinical data. AB - Fumarates (fumaric acid esters, FAEs) are orally administered systemic agents used for the treatment of psoriasis and multiple sclerosis. In 1994, a proprietary combination of FAEs was licensed for psoriasis by the German Drug Administration for use within Germany. Since then, fumarates have been established as one of the most commonly used treatments for moderate-to-severe psoriasis in Germany and other countries. The licensed FAE formulation contains dimethyl fumarate (DMF), as well as calcium, zinc, and magnesium salts of monoethyl fumarate (MEF). While the clinical efficacy of this FAE mixture is well established, the combination of esters on which it is based, and its dosing regimen, was determined empirically. Since the mid-1990s, the modes of action and contribution of the different FAEs to their overall therapeutic effect in psoriasis, as well as their adverse event profile, have been investigated in more detail. In this article, the available clinical data for DMF are reviewed and compared with data for the other FAEs. The current evidence substantiates that DMF is the main active compound, via its metabolic transformation to monomethyl fumarate (MMF). A recent phase III randomized and placebo-controlled trial including more than 700 patients demonstrated therapeutic equivalence when comparing the licensed FAE combination with DMF alone, in terms of psoriasis clearance according to the Psoriasis Area and Severity Index (PASI) and Physician's Global Assessment (PGA). Thus, DMF as monotherapy for the treatment of psoriasis is as efficacious as in combination with MEF, making the addition of such fumarate derivatives unnecessary. PMID- 29574577 TI - Minimally invasive and percutaneous surgery of the forefoot current techniques in 2018. AB - Minimally invasive and percutaneous techniques used to repair deformities of the forefoot have considerably developed recently. Like standard osteotomies, these techniques must take advantage of the mechanical advances made in the restoration of the foot's architecture. Instead of an endpoint, these techniques represent an additional tool implemented towards a rapid functional, post-operative recovery. This review describes the power of this surgery, details its techniques and lists its indications. We also report our own experience and review the recent literature. PMID- 29574578 TI - Bleaching and mortality of a photosymbiotic bioeroding sponge under future carbon dioxide emission scenarios. AB - The bioeroding sponge Cliona orientalis is photosymbiotic with dinoflagellates of the genus Symbiodinium and is pervasive on the Great Barrier Reef. We investigated how C. orientalis responded to past and future ocean conditions in a simulated community setting. The experiment lasted over an Austral summer under four carbon dioxide emission scenarios: a pre-industrial scenario (PI), a present day scenario (PD; control), and two future scenarios of combined ocean acidification and ocean warming, i.e., B1 (intermediate) and A1FI (extreme). The four scenarios also simulated natural variability of carbon dioxide partial pressure and temperature in seawater. Responses of C. orientalis generally remained similar between the PI and PD treatments. C. orientalis under B1 displayed a dramatic increase in lateral tissue extension, but bleached and displayed reduced rates of respiration and photosynthesis. Some B1 sponge replicates died by the end of the experiment. Under A1FI, strong bleaching and subsequent mortality of all C. orientalis replicates occurred at an early stage of the experiment. Mortality arrested bioerosion by C. orientalis under B1 and A1FI. Overall, the absolute amount of calcium carbonate eroded by C. orientalis under B1 or A1FI was similar to that under PI or PD at the end of the experiment. Although bioerosion rates were raised by short-term experimental acidification in previous studies, our findings from the photosymbiotic C. orientalis imply that the effects of bioerosion on reef carbonate budgets may only be temporary if the bioeroders cannot survive long-term in the future oceans. PMID- 29574579 TI - Competition along productivity gradients: news from heathlands. AB - The importance of competition in low productive habitats is still debated. Studies which simultaneously evaluate preemption of resources and consequences for population dynamics are needed for a comprehensive view of competitive outcomes. We cultivated two emblematic species of European heathlands (Calluna vulgaris and Molinia caerulea) in a nursery for 2 years at two fertility levels, reproducing the productivity gradient found in phosphorus (P)-depleted heathlands in southwest France. The second year, we planted Ulex europaeus seedlings, a ubiquitous heathland species, under the cover of the two species to evaluate its ability to regenerate. Half of the seedlings were placed in tubes for exclusion of competitor roots. We measured the development of the competitors aboveground and belowground and their interception of resources (light, water, inorganic P). Ulex seedlings' growth and survival were also measured. Our results on resources interception were consistent with species distribution in heathlands. Molinia, which dominates rich heathlands, was the strongest competitor for light and water in the rich soil. Calluna, which dominates poor heathlands, increased its root allocation in the poor soil, decreasing water and inorganic P availability. However, the impact of total competition and root competition on Ulex seedlings decreased in the poor soil. Other mechanisms, especially decrease of water stress under neighbouring plant cover, appeared to have more influence on the seedlings' response. We found no formal contradiction between Tilman and Grime's theories. Root competition has a primary role in acquisition of soil resources in poor habitats. However, the importance of competition decreases with decreasing fertility. PMID- 29574580 TI - Simulated drought regimes reveal community resilience and hydrological thresholds for altered decomposition. AB - Future climate scenarios forecast a 10-50% decline in rainfall in Eastern Amazonia. Altered precipitation patterns may change important ecosystem functions like decomposition through either changes in physical and chemical processes or shifts in the activity and/or composition of species. We experimentally manipulated hydroperiods (length of wet:dry cycles) in a tank bromeliad ecosystem to examine impacts on leaf litter decomposition. Gross loss of litter mass over 112 days was greatest in continuously submersed litter, lowest in continuously dry litter, and intermediate over a range of hydroperiods ranging from eight cycles of 7 wet:7 dry days to one cycle of 56 wet:56 dry days. The resilience of litter mass loss to hydroperiod length is due to a shift from biologically assisted decomposition (mostly microbial) at short wet:dry hydroperiods to physicochemical release of dissolved organic matter at longer wet:dry hydroperiods. Biologically assisted decomposition was maximized at wet:dry hydroperiods falling within the range of ambient conditions (12-22 consecutive dry days) but then declined under prolonged wet:dry hydroperiods (28 and 56 dry days. Fungal:bacterial ratios showed a similar pattern as biologically assisted decomposition to hydroperiod length. Our results suggest that microbial communities confer functional resilience to altered hydroperiod in tank bromeliad ecosystems. We predict a substantial decrease in biological activity relevant to decomposition under climate scenarios that increase consecutive dry days by 1.6- to 3.2-fold in our study area, whereas decreased frequency of dry periods will tend to increase the physicochemical component of decomposition. PMID- 29574581 TI - New Algorithm for the Prediction of Cardiovascular Risk in Symptomatic Adults with Stable Chest Pain. AB - PURPOSE OF REVIEW: To review the landmark studies in predicting obstructive coronary artery disease (CAD) in symptomatic patients with stable chest pain and identify better prediction tools and propose a simplified algorithm to guide the health care providers in identifying low risk patients to defer further testing. RECENT FINDINGS: There are a few risk prediction models described for stable chest pain patients including Diamond-Forrester (DF), Duke Clinical Score (DCS), CAD Consortium Basic, Clinical, and Extended models. The CAD Consortium models demonstrated that DF and DCS models overestimate the probability of CAD. All CAD Consortium models performed well in the contemporary population. PROMISE trial secondary data results showed that a clinical tool using readily available ten very low-risk pre-test variables could discriminate low-risk patients to defer further testing safely. In the contemporary population, CAD Consortium Basic or Clinical model could be used with more confidence. Our proposed simple algorithm would guide the physicians in selecting low risk patients who can be managed conservatively with deferred testing strategy. Future research is needed to validate our proposed algorithm to identify the low-risk patients with stable chest pain for whom further testing may not be warranted. PMID- 29574583 TI - The Broader Autism Phenotype and Visual Perception in Children. AB - Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a pediatric sample with a range of clinical features. Visual processing was comprehensively characterized using the test of visual perceptual skills (TVPS), a standardized test of visual perception with seven subtests that capture a range of visual processing abilities. The TVPS Figure Ground (TVPS-FG) subtest requires an individual to disembed a smaller figure from a larger scene. TVPS-FG subtest scores were positively correlated with children's autism features as measured by a parental report of the Broader Autism Phenotype Questionnaire (BAP-Q). The correlation with BAP-Q was specific to the TVPS-FG subtest, as the other TVPS subtest scores were not significantly related to the BAP-Q. This adds to the growing body of research documenting that atypical visual processing is associated with the autism phenotype and highlights the importance of capturing quantitative traits in heterogeneous developmental brain disorders. PMID- 29574582 TI - Prion protein cleavage fragments regulate adult neural stem cell quiescence through redox modulation of mitochondrial fission and SOD2 expression. AB - Neurogenesis continues in the post-developmental brain throughout life. The ability to stimulate the production of new neurones requires both quiescent and actively proliferating pools of neural stem cells (NSCs). Actively proliferating NSCs ensure that neurogenic demand can be met, whilst the quiescent pool makes certain NSC reserves do not become depleted. The processes preserving the NSC quiescent pool are only just beginning to be defined. Herein, we identify a switch between NSC proliferation and quiescence through changing intracellular redox signalling. We show that N-terminal post-translational cleavage products of the prion protein (PrP) induce a quiescent state, halting NSC cellular growth, migration, and neurite outgrowth. Quiescence is initiated by the PrP cleavage products through reducing intracellular levels of reactive oxygen species. First, inhibition of redox signalling results in increased mitochondrial fission, which rapidly signals quiescence. Thereafter, quiescence is maintained through downstream increases in the expression and activity of superoxide dismutase-2 that reduces mitochondrial superoxide. We further observe that PrP is predominantly cleaved in quiescent NSCs indicating a homeostatic role for this cascade. Our findings provide new insight into the regulation of NSC quiescence, which potentially could influence brain health throughout adult life. PMID- 29574584 TI - Phase I study of combined indomethacin and platinum-based chemotherapy to reduce platinum-induced fatty acids. AB - PURPOSE: Chemotherapy-resistance remains a major obstacle to effective anti cancer treatment. We previously showed that platinum analogs cause the release of two fatty acids. These platinum-induced fatty acids (PIFAs) induced complete chemoresistance in mice, whereas co-administration of a COX-1 inhibitor, indomethacin, prevented PIFA release and significantly enhanced chemosensitivity. To assess the safety of combining indomethacin with platinum-based chemotherapy, and to explore its efficacy and associated PIFA levels, a multi-center phase I trial was conducted. METHODS: The study was comprised of two arms: oxaliplatin plus capecitabine (CAPOX, arm I) and cisplatin plus gemcitabine, capecitabine or 5FU (arm II) in patients for whom these regimens were indicated as standard care. Indomethacin was escalated from 25 to 75 mg TID, using a standard 3 * 3 design per arm, and was administered orally 8 days around chemo-infusion from cycle two onwards. PIFA levels were measured before and after treatment initiation, with and without indomethacin. RESULTS: Thirteen patients were enrolled, of which ten were evaluable for safety analyses. In arm I, no dose-limiting toxicities were observed, and all indomethacin dose levels were well-tolerated. Partial responses were observed in three patients (30%). Indomethacin lowered plasma levels of 12-S hydroxy-5,8,10-heptadecatrienoic acid (12-S-HHT), whereas 4,7,10,13 hexadecatetraenoic acid (16:4(n-3)) levels were not affected. Only one patient was included in arm II; renal toxicity led to closure of this cohort. CONCLUSIONS: Combined indomethacin and CAPOX treatment is safe and reduces the concentrations of 12-S-HHT, which may be associated with improved chemosensitivity. The recommended phase II dose is 75 mg indomethacin TID given 8 days surrounding standard dosed CAPOX. PMID- 29574585 TI - Direct and indirect nigrofugal projections to the nucleus reticularis pontis caudalis mediate in the motor execution of the acoustic startle reflex. AB - The acoustic startle reflex (ASR) is a short and intense defensive reaction in response to a loud and unexpected acoustic stimulus. In the rat, a primary startle pathway encompasses three serially connected central structures: the cochlear root neurons, the giant neurons of the nucleus reticularis pontis caudalis (PnC), and the spinal motoneurons. As a sensorimotor interface, the PnC has a central role in the ASR circuitry, especially the integration of different sensory stimuli and brain states into initiation of motor responses. Since the basal ganglia circuits control movement and action selection, we hypothesize that their output via the substantia nigra (SN) may interplay with the ASR primary circuit by providing inputs to PnC. Moreover, the pedunculopontine tegmental nucleus (PPTg) has been proposed as a functional and neural extension of the SN, so it is another goal of this study to describe possible anatomical connections from the PPTg to PnC. Here, we made 6-OHDA neurotoxic lesions of the SN pars compacta (SNc) and submitted the rats to a custom-built ASR measurement session to assess amplitude and latency of motor responses. We found that following lesion of the SNc, ASR amplitude decreased and latency increased compared to those values from the sham-surgery and control groups. The number of dopamine neurons remaining in the SNc after lesion was also estimated using a stereological approach, and it correlated with our behavioral results. Moreover, we employed neural tract-tracing techniques to highlight direct projections from the SN to PnC, and indirect projections through the PPTg. Finally, we also measured levels of excitatory amino acid neurotransmitters in the PnC following lesion of the SN, and found that they change following an ipsi/contralateral pattern. Taken together, our results identify nigrofugal efferents onto the primary ASR circuit that may modulate motor responses. PMID- 29574587 TI - Can Nuclear Imaging Techniques Predict Patient Outcome and Guide Medical Management in Hereditary Transthyretin Cardiac Amyloidosis? AB - PURPOSE OF REVIEW: Nuclear imaging recently gained a key role in the diagnosis and prognostic assessment of transthyretin (TTR)-related cardiac amyloidosis. This review aims at summarizing the state-of-the art regarding the implementation of nuclear imaging in the management of hereditary mutated TTR-cardiac amyloidosis (mTTR-CA). RECENT FINDINGS: Although cardiac uptake of bone tracers is acknowledged as a specific marker of TTR amyloid cardiac burden, recent studies validated the implementation of bone scan in the flow chart for non invasive diagnosis and follow-up of CA in multicenter trials. Simultaneously, cardiac denervation evidenced by MIBG scintigraphy proved to be a strong and independent prognostic marker of poor outcome in mTTR-CA. By its unique ability to assess both amyloid burden and cardiac denervation, nuclear imaging may prove useful as part of multimodality imaging tools to trigger treatment initiation and monitoring in patients with mTTR-CA. PMID- 29574586 TI - Precision Medicine in Chronic Rhinosinusitis with Nasal Polyps. AB - PURPOSE OF REVIEW: Chronic rhinosinusitis is a disease with high prevalence, significant impact on health-related quality of life (HRQoL) and it is associated with substantial healthcare and productivity costs. We face an urgent need to improve the level of disease control and achieve higher patient satisfaction and disease prevention. Precision medicine is increasingly recognized as the way forward in optimal patient care. The combination of personalized care, prevention of disease, prediction of success of treatment, and participation of the patient in the elaboration of the treatment plan is expected to guarantee the best possible therapeutic approach for individuals suffering from a chronic disabling condition. RECENT FINDINGS: This is a narrative review on the current state of endotypes, biomarkers, and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses. Different phenotypes of rhinitis and chronic rhinosinusitis (CRS) have been described based on symptom severity and duration, atopy status, level of control, comorbidities, and presence or absence of nasal polyps in CRS. The underlying pathophysiological mechanisms are diverse, with different endotypes being recognized. Novel emerging therapies are targeting specific pathophysiological pathways or endotypes. This endotype-driven treatment approach requires careful selection of the patient population who might benefit from a specific treatment. This review provides a comprehensive overview of the current state of endotypes, biomarkers and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses. PMID- 29574588 TI - Should Primary Prevention ICDs Still Be Placed in Patients with Non-ischemic Cardiomyopathy? A Review of the Evidence. AB - PURPOSE OF REVIEW: Recent evidence has suggested that implantable defibrillator (ICD) in non-ischemic cardiomyopathy (NICM) may not offer mortality benefit in the presence of guideline-directed medical therapy (GDMT) and cardiac resynchronization therapy (CRT). RECENT FINDINGS: Despite significant benefits of GDMT and CRT, current evidence is derived from ICD trials that rely predominantly on reduced left ventricular ejection fraction alone (LVEF). The majority of patients with sudden cardiac death (SCD) have LVEF > 30% indicating that LVEF by itself is an inadequate predictor of SCD. The Danish study to assess the efficacy of ICD in patients with non-ischemic systolic heart failure on mortality (DANISH) highlights the importance of better risk stratifying NICM patients for ICD implantation. Assessment of life expectancy, comorbidities, presence of advanced heart failure, etiology of NICM, and the presence of myocardial fibrosis can help risk stratify ICD beyond LVEF. Genetics and biomarkers can be of further assistance in risk stratification. PMID- 29574589 TI - Complete genome sequence analysis of PS2, a novel T4-like bacteriophage that infects Serratia marcescens clinical isolates. AB - In this study, we isolated and characterized a lytic phage, named vB_SmaM_PS2 (abbreviated as PS2), which can infect Serratia marcescens clinical isolates. Morphologically, phage PS2 can be classified within the Myoviridae family. The 167,276 bp double-stranded DNA genome of PS2 possesses 41.7% GC content. A total of 276 protein-coding genes and 4 tRNA genes were predicted in the PS2 genome. Of the 276 genes, 131 (47%) encoded T4-like genes, most of which are DNA replication and virion structural genes. Therefore, phage PS2 should be a new member of the T4-like Serratia phage. PMID- 29574590 TI - Sequence analysis and genomic organization of a new insect iflavirus, Sogatella furcifera honeydew virus 1. AB - A novel iflavirus, tentatively named "Sogatella furcifera honeydew virus 1" (SFHV1), discovered through transcriptome sequencing analysis of white-backed planthoppers (Sogatella furcifera) collected in southern China, is described here. The full genome of SFHV1 is 10,837 nucleotides (nt) long, including the polyA tail, and shares 65.5% and 64.5% genomic identity with Laodelphax striatellus picorna-like virus 2 and Laodelphax striatella honeydew virus 1, respectively. On the basis of the phylogenetic analysis of the complete genomic sequence and the deduced RdRp amino acid sequence of SFHV1 with other iflaviruses, we suggest that it is a member of a new species in the genus Iflavirus, family Iflaviridae. PMID- 29574591 TI - Capillary cerebral amyloid angiopathy in Alzheimer's disease: association with allocortical/hippocampal microinfarcts and cognitive decline. AB - Cerebral amyloid angiopathy (CAA) is caused by the deposition of the amyloid beta protein (Abeta) in the wall of cerebral and leptomeningeal blood vessels and is related to Alzheimer's disease (AD). Capillary Abeta deposition is observed in a subset of CAA cases and represents a distinct type of CAA named capillary CAA or CAA type 1. This type of CAA is strongly associated with the presence of the apolipoprotein E epsilon4 allele. CAA type 1-associated AD cases often exhibit a more severe Abeta plaque pathology but less widespread neurofibrillary tangle (NFT) pathology. The objective of this study was to analyze whether capillary CAA and its effects on cerebral blood flow have an impact on dementia. To address this objective, we performed neuropathological evaluation of 284 autopsy cases of demented and non-demented individuals. We assessed the presence of CAA and its subtypes as well as for that of hemorrhages and infarcts. Capillary CAA and CAA severity were associated with allocortical microinfarcts, comprising the CA1 region of the hippocampus. Allocortical microinfarcts, capillary CAA and CAA severity were, thereby, associated with cognitive decline. In conclusion, allocortical microinfarcts, CAA severity, and the capillary type of CAA were associated with one another and with the development of cognitive decline. Thus, AD cases with CAA type 1 (capillary CAA) appear to develop dementia symptoms not only due to AD-related Abeta plaque and NFT pathology but also due to hippocampal microinfarcts that are associated with CAA type 1 and CAA severity, and that damage a brain region important for memory function. PMID- 29574593 TI - Longitudinal brain activation changes related to electrophysiological findings in patients with cervical spondylotic myelopathy before and after spinal cord decompression: an fMRI study. AB - BACKGROUND: Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction, potentially leading to severe disability. Abnormal cervical spine magnetic resonance imaging (MRI) and motor evoked potentials (MEPs) are independent predictors of disease progression. Abnormal MRI is accompanied by various activation changes in functional brain MRI (fMRI), whereas preoperative and postoperative fMRI adaptations associated with abnormal preoperative MEP remain unknown. METHODS: Twenty patients (9 males, average age 56.6) with evidence of spinal cord compression on MRI and clinical signs of mild CSM were included. Participants were classified according to their preoperative MEP and underwent three brain fMRI examinations: before surgery, 6, and 12 months after surgery while performing repeated extension-flexion of each wrist. RESULTS: Functional MRI activation was compared between two subsets of patients, with normal and clearly abnormal MEP (right wrist: 8 vs. 8; left wrist: 7 vs. 9). At baseline, abnormal MEPs were associated with hyperactivation in the cerebellum. At the first follow-up, further hyperactivations emerged in the contralateral sensorimotor cortices and persisted for 1 year. In normal baseline MEP, activation mostly decreased in the ipsilateral sensorimotor cortex postoperatively. The ipsilateral sensorimotor activation after 1-year follow-up correlated with baseline MEP. CONCLUSIONS: Abnormal corticospinal MEP findings in cervical spondylotic myelopathy were associated with differences in brain activation, which further increased after spinal cord decompression and did not resolve within 12-month follow-up. In summary, surgery may come too late for those patients with abnormal MEP to recover completely despite their mild clinical signs and symptoms. PMID- 29574592 TI - Ectopic Expression of Rice PYL3 Enhances Cold and Drought Tolerance in Arabidopsis thaliana. AB - Abscisic acid (ABA) plays an important role in plant development and adaptation to abiotic stresses. The pyrabactin resistance-like (PYL) gene family has been characterized as intracellular ABA receptors in Arabidopsis. We describe here the functional characterization of PYL3 ABA receptor from a drought-tolerant rice landrace Nagina 22 (N22). The induced expression level of the PYL3 transcript was observed in the N22 under different stress treatments, including cold, drought, high temperature, salt and ABA. In contrast, the expression of PYL3 was down regulated in drought-susceptible rice cv. IR64 in response to above stresses. C terminal GFP translational fusion of OsPYL3 was localized to both cytosol and nucleus explaining in part functional conservation of PYL protein as ABA receptor. Arabidopsis transgenic lines overexpressing OsPYL3 were hypersensitive to ABA suggesting ABA signaling pathway-dependent molecular response of the OsPYL3. Further, constitutive overexpression of OsPYL3 in Arabidopsis led to improved cold and drought stress tolerance. Thus, OsPYL3 identified in this study could be a good candidate for genetic improvement of cold and drought stress tolerance of rice and other crop plants. PMID- 29574594 TI - Endomyocardial biopsy at the time of ablation or device implantation. AB - PURPOSE: Cardiomyopathies frequently lead to conduction system disease and/or arrhythmias necessitating device therapy, catheter ablation, or both. Endomyocardial biopsy (EMB) is avoided with recent right ventricle (RV) lead implants and optimal timing is uncertain. We determined outcomes of EMB at the time of ablation or device implantation procedures. METHODS: We retrospectively analyzed patients undergoing EMB during their electrophysiological procedure between January 2014 and July 2016. EMB was obtained using cephalic/subclavian access prior to device implants or femoral venous/arterial access after ablation procedures. Sites of electrogram (EGM) abnormality and/or scar on imaging were targeted when possible. RESULTS: Twenty-five patients (23 male, 59.7 +/- 15.1 years) were included. Sixteen had reduced ejection fraction. EMB was performed during device implants in 9, during ablation in 13, and during combined procedures in 3 patients. RV and left ventricle (LV) EMB were obtained in 19 and 6 patients, respectively. 3.9 +/- 1.8 samples/patient (median 4) were obtained. EMB yielded a diagnosis in 7 (28%, all RV) patients (4 cardiac implantable electronic device implantation, 2 ablation, and 1 both): cardiac amyloid in 4, lymphocytic myocarditis in 2, and cardiac sarcoid in 1. All 7 patients had imaging or voltage abnormalities in the chamber biopsied. Abnormal but non diagnostic findings, most commonly fibrotic change, were found in 14 patients. At mean follow-up of 1.1 +/- 0.9 years, 5 other patients received a clinical diagnosis (3 cardiac sarcoid, 1 arrhythmogenic cardiomyopathy, and 1 Brugada syndrome/arrhythmogenic cardiomyopathy overlap syndrome). Two patients developed minor device pocket hematomas and one developed pericardial effusion (underwent concomitant epicardial mapping and ablation for VT). CONCLUSIONS: RV or LV EMB can be performed safely during EP procedures and can assist with diagnosis, influencing management. EGM-guided EMB in patients presenting with scar-related VT was low yield for specific pathologies. PMID- 29574595 TI - High rate of persistent iatrogenic atrial septal defect after single transseptal puncture for cryoballoon pulmonary vein isolation. AB - PURPOSE: Congenital atrial septal defect (ASD) is associated with increased morbidity, whereas little is known about the rate of spontaneous closure, associated clinical and echocardiographic parameters, or complications of iatrogenic atrial septal defect (iASD) beyond 1 year of follow-up. Persistent iASD after transseptal puncture for PVI has been described in up to 38% of small cohorts of patients in short-term follow-up after transseptal puncture. We sought to investigate the course of iASD after single transseptal puncture for first pulmonary vein isolation (PVI) with cryoballoon, along with possible risk factors for persistent iASD. METHODS: After a first PVI with cryoballoon, 102 patients (64 +/- 10 years, 64% male) underwent long-term clinical follow-up and comprehensive transthoracic and transesophageal echocardiographic study. RESULTS: Prevalence of iASD after PVI was 37% after 2.9 (1.6-4.9) years. No clinical complications or deterioration of echocardiographic parameters were associated with iASD. Lower left atrial appendage flow velocity was associated with higher risk of persistence of iASD (3.5% for every 1 cm/s decrease, p = 0.002). CONCLUSIONS: Despite a high rate of iASD after cryoballoon PVI in long-term follow-up, this was not associated with increased clinical complications. Lower LAA velocity was associated with higher risk of persistent iASD. Repeated routine echocardiographic follow-up may not be necessary in these patients. PMID- 29574596 TI - Characterization and modelling of looming-sensitive neurons in the crab Neohelice. AB - Looming-sensitive neurons (LSNs) are motion-sensitive neurons tuned for detecting imminent collision. Their main characteristic is the selectivity to looming (a 2D representation of an object approach), rather than to receding stimuli. We studied a set of LSNs by performing surface extracellular recordings in the optic nerve of Neohelice granulata crabs, and characterized their response against computer-generated visual stimuli with different combinations of moving edges, highlighting different components of the optical flow. In addition to their selectivity to looming stimuli, we characterized other properties of these neurons, such as low directionality; reduced response to sustained excitement; and an inhibition phenomenon in response to visual stimuli with dense optical flow of expansion, contraction, and translation. To analyze the spatio-temporal processing of these LSNs, we proposed a biologically plausible computational model which was inspired by previous computational models of the locust lobula giant motion detector (LGMD) neuron. The videos seen by the animal during electrophysiological experiments were applied as an input to the model which produced a satisfactory fit to the measured responses, suggesting that the computation performed by LSNs in a decapod crustacean appears to be based on similar physiological processing previously described for the LGMD in insects. PMID- 29574597 TI - Reducing post-tonsillectomy haemorrhage rates through a quality improvement project using a Swedish National quality register: a case study. AB - PURPOSE: Tonsillectomy (TE) is one of the most frequently performed ENT surgical procedures. Post-tonsillectomy haemorrhage (PTH) is a potentially life threatening complication of TE. The National Tonsil Surgery Register in Sweden (NTSRS) has revealed wide variations in PTH rates among Swedish ENT centres. In 2013, the steering committee of the NTSRS, therefore, initiated a quality improvement project (QIP) to decrease the PTH incidence. The aim of the present study was to describe and evaluate the multicentre QIP initiated to decrease PTH rates. METHODS: Six ENT centres, all with PTH rates above the Swedish average, participated in the 7-month quality improvement project. Each centre developed improvement plans describing the intended changes in clinical practice. The project's primary outcome variable was the PTH rate. Process indicators, such as surgical technique, were also documented. Data from the QIP centres were compared with a control group of 15 surgical centres in Sweden with similarly high PTH rates. Data from both groups for the 12 months prior to the start of the QIP were compared with data for the 12 months after the QIP. RESULTS: The QIP centres reduced the PTH rate from 12.7 to 7.1% from pre-QIP to follow-up; in the control group, the PTH rate remained unchanged. The QIP centres also exhibited positive changes in related key process indicators, i.e., increasing the use of cold techniques for dissection and haemostasis. CONCLUSIONS: The rates of PTH can be reduced with a QIP. A national quality register can be used not only to identify areas for improvement but also to evaluate the impact of subsequent improvement efforts and thereby guide professional development and enhance patient outcomes. PMID- 29574598 TI - Synchronized roles of pannexin and connexin in nasal mucosal epithelia. AB - BACKGROUND: Nasal mucosal epithelial cells express connexins, the prototypical gap junction proteins, and pannexins, a new family of channel proteins homologous to the invertebrate gap junction proteins. The physiological and pathophysiological roles of these transmembrane proteins in nasal mucosa are largely still unknown. PURPOSE: Pannexins participate in ATP release into the extracellular space in various tissues, and ATP plays important roles in mucociliary clearance, especially by regulating ciliary beat activity. Therefore, we focused on the functional relationship between connexins, pannexin-1, ATP release, and mucociliary clearance in nasal epithelia. RESULTS AND CONCLUSIONS: Connexins participate in the generation of intercellular calcium waves, in which calcium-mediated signaling responses spread to contiguous cells through the gap junction formed by connexins to transmit calcium signaling throughout the airway epithelium. Pannexins in the nasal mucosa may contribute to not only ciliary beat modulation via ATP release, but also regulation of mucus blanket components via H2O efflux. The synchronized roles of pannexin and connexin may provide a new insight into effective mucociliary clearance systems in nasal mucosa. PMID- 29574599 TI - Pharyngeal fistulas after total laryngectomy with and without tracheostoma plasty according to Herrmann. AB - PURPOSE: Pharyngeal fistula (PF) is one of the most common complications after total laryngectomy (TL). The tracheostoma plasty technique according to Herrmann (TPH) represents an alternative surgical technique to shape the tracheostoma. The aim of this study was to determine whether the performance of a TPH affects the incidence of PF after TL. A secondary aim was to identify potential risk factors for the development of PF with regard to TPH. METHODS: Retrospective evaluation of records of 151 consecutive patients at two tertiary care centers with regard to the occurrence and risk factors of PF after TL with and without TPH. RESULTS: 60 patients with TPH and 91 patients without TPH contributed to the results. The overall incidence of PF was 21.2% (32 out of 151). 23.3% (14 out of 60) of patients with TPH and 19.8% (18 of 91) of patients without TPH developed a PF (p = 0.91). Binary logistic regression analysis revealed significant influence of salvage surgery on the risk to develop PF (odds ratio = 2.9; 95% CI 1.16-7.23; p = 0.026). The occurrence of PF was not significantly influenced by any other investigated factors including performance of TPH. CONCLUSIONS: Performance of TPH after TL does not increase the incidence of PF. Thus, TPH can be considered as a safe alternative surgical technique for the shaping of the tracheostoma following TL. PMID- 29574600 TI - Rates and predictors of futile recanalization in patients undergoing endovascular treatment in a multicenter clinical trial. AB - PURPOSE: The phenomenon of futile recanalization, defined as lack of clinical benefit despite angiographic recanalization, is an important limitation of endovascular treatment for acute ischemic stroke. We aim to characterize the occurrence and predictors of futile recanalization in the endovascular arm of the Interventional Management of Stroke (IMS) III trial. METHODS: Patients with near complete or complete recanalization (TICI grades 2b and 3) were divided according to functional outcome at 3 months into "meaningful recanalization," defined as mRS score 0-2, and "futile recanalization," mRS score 3-6. Multivariate analysis was performed to identify predictors of futile recanalization. RESULTS: Futile recanalization was observed in 61 (47%) of 130. Compared to meaningful recanalization group, the futile recanalization group had higher proportion of women (62.3 vs. 43.5%; p = 0.032), higher incidence of diabetes mellitus (29.5 vs. 8.7%; p = 0.004) and coronary artery disease (27.9 vs. 13%; p = 0.05), higher baseline National Institutes of Health Stroke Scale (NIHSS) scores (median [range] 19 [11-31] vs. 15 [8-26], p < 0.001), higher baseline serum glucose (7.6 +/- 2.6 vs. 6.7 +/- 1.7 mmol/L; p = 0.039), and longer onset-to-start of endovascular treatment time (265.8 +/- 48.3 vs. 239.2 +/- 47.7 min; p = 0.007). In multivariate analysis, NIHSS (OR 1.3; 95% CI 1.1-1.4), female gender (OR 3.0; 95% CI 1.1-8.2), and onset-to-start of endovascular treatment time (OR 1.2; 95% CI 1.1-1.3) were independent predictors of futile recanalization. CONCLUSION: In IMS III, futile recanalization was common. Delay in endovascular treatment is the only modifiable risk factor. Additional strategies for non-modifiable risk factors-female gender and high NIHSS-need to be identified. PMID- 29574601 TI - Headache and Its Management in Patients With Multiple Sclerosis. AB - PURPOSE OF REVIEW: The purpose of this review was to discuss the prevalence, impact, pathophysiology, and treatment of headaches (H/As) in patients with multiple sclerosis (MS). RECENT FINDINGS: Headaches and multiple sclerosis are more common in women than in men with the ratio of female to male being 3:1. It is not entirely clear if there is a correlation or an incidental comorbidity of two neurological conditions. A review of the literature shows a variable prevalence of H/As in MS patients. Using the International Classification of Headache Disorders (ICHD) criteria, the primary type of H/As, especially migraine, is the most common type seen in patients with MS. One of the theories of the pathophysiologic mechanisms of migraine in MS patients is inflammation leading to demyelinating lesions in the pain-producing centers in the midbrain. Secondary H/As due to MS medications such as interferons are also frequently present. H/As can be a cause for significant comorbidity in patients with MS. The treatment of H/As in patients with MS should be addressed in the same fashion as in the non-MS population, which is a combination of pharmacological and non pharmacological methods. Preventive medicines for the H/As should be carefully selected because of their side effect profiles. Acute attacks of migraines can be treated with medications such as triptans. Patients with MS who have migraine H/As should be educated about the phenomenon of overuse H/As, keeping headache journals, avoiding stress, and monitoring sleeping habits. The presence of depression in patients with MS and migraine affects quality of life (QOL) and should also be addressed for better outcomes. PMID- 29574602 TI - Enhanced lincomycin production by co-overexpression of metK1 and metK2 in Streptomyces lincolnensis. AB - Streptomyces lincolnensis is generally utilized for the production of lincomycin A (Lin-A), a clinically useful antibiotic to treat Gram-positive bacterial infections. Three methylation steps, catalyzed by three different S adenosylmethionine (SAM)-dependent methyltransferases, are required in the biosynthesis of Lin-A, and thus highlight the significance of methyl group supply in lincomycin production. In this study, we demonstrate that externally supplemented SAM cannot be taken in by cells and therefore does not enhance Lin-A production. Furthermore, bioinformatics and in vitro enzymatic assays revealed there exist two SAM synthetase homologs, MetK1 (SLCG_1651) and MetK2 (SLCG_3830) in S. lincolnensis that could convert L-methionine into SAM in the presence of ATP. Even though we attempted to inactivate metK1 and metK2, only metK2 was deleted in S. lincolnensis LCGL, named as DeltametK2. Following a reduction of the intracellular SAM concentration, DeltametK2 mutant exhibited a significant decrease of Lin-A in comparison to its parental strain. Individual overexpression of metK1 or metK2 in S. lincolnensis LCGL either elevated the amount of intracellular SAM, concomitant with 15% and 22% increase in Lin-A production, respectively. qRT-PCR assays showed that overexpression of either metK1 or metK2 increased the transcription of lincomycin biosynthetic genes lmbA and lmbR, and regulatory gene lmbU, indicating SAM may also function as a transcriptional activator. When metK1 and metK2 were co-expressed, Lin-A production was increased by 27% in LCGL, while by 17% in a high-yield strain LA219X. PMID- 29574603 TI - Nationwide survey of therapy-related leukemia in childhood in Japan. AB - Therapy-related leukemia (t-leukemia) is associated with dismal prognosis. Published pediatric t-leukemia data are somewhat outdated and may not reflect recent advances in treatment. We report a retrospective nationwide survey of patients diagnosed between 2000 and 2013 in Japan. We identified 43 patients with pediatric t-leukemia; 33 had t-acute myeloid leukemia (t-AML), eight had t-acute lymphoblastic leukemia (t-ALL) and two had t-acute undifferentiated leukemia. Median age at onset and latency were 12 years and 3.8 years, respectively, consistent with previous reports. Of t-AML patients, 63.6% harbored topoisomerase II inhibitor (topo II)-related genetic abnormalities, while only 12.5% of t-ALL patients had such alterations, suggesting that topo II is not key to t-ALL leukemogenesis. The 7-year overall survival (OS) for all 43 patients was 39.2 +/- 11.6%. The 5-year OS was 50 +/- 20.4% in t-ALL, and 55.2 +/- 11.0% in t-AML. Allogeneic hematopoietic cell transplantation (allo-HCT) was associated with superior 5-year OS (HCT(+) vs. HCT(-), 78.8 vs. 12.1%; p < 0.001), and 26 of 32 patients received allo-HCT in complete remission (CR). Only allo-HCT was associated with superior OS on multivariate analysis (HR 0.003, 95% CI 0.0001 0.098; p < 0.001). These findings suggest that allo-HCT in CR improves pediatric t-leukemia outcomes. PMID- 29574604 TI - Evolution of Melanoma Antigen-A11 (MAGEA11) During Primate Phylogeny. AB - Melanoma antigen-A11 (MAGE-A11) is an X-linked and primate-specific steroid hormone receptor transcriptional coregulator and proto-oncogenic protein whose increased expression promotes the growth of prostate cancer. The MAGEA11 gene is expressed at low levels in normal human testis, ovary, and endometrium, and at highest levels in castration-resistant prostate cancer. Annotated genome predictions throughout the surviving primate lineage show that MAGEA11 acquired three 5' coding exons unique within the MAGEA subfamily during the evolution of New World monkeys (NWM), Old World monkeys (OWM), and apes. MAGE-A11 in all primates has a conserved FXXIF coactivator-binding motif that suggests interaction with p160 coactivators contributed to its early evolution as a transcriptional coregulator. An ancestral form of MAGE-A11 in the more distantly related lemur has significant amino acid sequence identity with human MAGE-A11, but lacks coregulator activity based on the absence of the three 5' coding exons that include a nuclear localization signal (NLS). NWM MAGE-A11 has greater amino acid sequence identity than lemur to human MAGE-A11, but inframe premature stop codons suggest that MAGEA11 is a pseudogene in NWM. MAGE-A11 in OWM and apes has nearly identical 5' coding exon amino acid sequence and conserved interaction sites for p300 acetyltransferase and cyclin A. We conclude that the evolution of MAGEA11 within the lineage leading to OWM and apes resulted in steroid hormone receptor transcriptional coregulator activity through the acquisition of three 5' coding exons that include a NLS sequence and nonsynonymous substitutions required to interact with cell cycle regulatory proteins and transcription factors. PMID- 29574605 TI - Climate Change and the Impact on Respiratory and Allergic Disease: 2018. AB - PURPOSE OF REVIEW: The purpose of this paper is to review allergic respiratory disease related to indoor and outdoor exposures and to examine the impact of known and projected changes in climate. The global burden of disease directly attributed to climate change is very difficult to measure and becomes more challenging when the capacity of humans to adapt to these changes is taken into consideration. Allergic respiratory disease, such as asthma, is quite heterogenous, though closely associated with environmental and consequently immunologic interaction. Where is the tipping point? RECENT FINDINGS: Our climate has been measurably changing for the past 100 years. It may indeed be the most significant health threat of the twenty-first century, and consequently tackling climate change may be the greatest health opportunity. The impacts of climate change on human health are varied and coming more into focus. Direct effects, such as heatwaves, severe weather, drought, and flooding, are apparent and frequently in the news. Indirect or secondary effects, such as changes in ecosystems and the impact on health, are less obvious. It is these changes in ecosystems that may have the greatest impact on allergic and respiratory diseases. This review will explore some ways that climate change, current and predicted, influences respiratory disease. Discussion will focus on changing pollen patterns, damp buildings with increased mold exposure, air pollution, and heat stress. PMID- 29574607 TI - The effect of bovine colostrum supplementation on intestinal injury and circulating intestinal bacterial DNA following exercise in the heat. AB - PURPOSE: Exercise-induced changes in intestinal permeability are exacerbated in the heat. The aim of this study was to determine the effect of 14 days of bovine colostrum (Col) supplementation on intestinal cell damage (plasma intestinal fatty acid-binding protein, I-FABP) and bacterial translocation (plasma bacterial DNA) following exercise in the heat. METHODS: In a double-blind, placebo controlled, crossover design, 12 males completed two experimental arms (14 days of 20 g/day supplementation with Col or placebo, Plac) consisting of 60 min treadmill running at 70% maximal aerobic capacity (30 degrees C, 60% relative humidity). Blood samples were collected pre-exercise (Pre-Ex), post-exercise (Post-Ex) and 1 h post-exercise (1 h Post-Ex) to determine plasma I-FABP concentration, and bacterial DNA (for an abundant gut species, Bacteroides). RESULTS: Two-way repeated measures ANOVA revealed an arm * time interaction for I FABP (P = 0.005, with greater Post-Ex increase in Plac than Col, P = 0.01: Plac 407 +/- 194% of Pre-Ex vs Col, 311 +/- 134%) and 1 h Post-Ex (P = 0.036: Plac 265 +/- 80% of Pre-Ex vs Col, 229 +/- 56%). There was no interaction (P = 0.904) but there was a main effect of arm (P = 0.046) for plasma Bacteroides/total bacterial DNA, with lower overall levels evident in Col. CONCLUSION: This is the first investigation to demonstrate that Col can be effective at reducing intestinal injury following exercise in the heat, but exercise responses (temporal pattern) of bacterial DNA were not influenced by Col (although overall levels may be lower). PMID- 29574606 TI - Effectiveness of Psycho-Physiological Portable Devices to Analyse Effect of Ergogenic Aids in Military Population. AB - Caffeine is one of the ergogenic substances most used by warfighters in current operation areas, but the effect on the organic response and operational performed is already poor knowledge. This research aimed to study the acute effect of 400 mg of caffeine monohydrate on the psycho-physiological response and rifle marksmanship of warfighters during a close quarter combat simulation. We analysed parameter of heart rate, blood lactate, cortical arousal, state anxiety and marksmanship of 20 Spanish Army veteran warfighters before and after a close quarter combat simulation in a double-blind procedure, also a correlation analysis was conducted between all the study variables. Marksmanship of warfighters did not improve with the caffeine ingestion, but it produced an increase in blood lactate concentration (caffeine: 1.9 +/- 0.5 vs. 9.2 +/- 1.1 mmol.l-1; placebo: 1.8 +/- 0.7 vs. 6.9 +/- 2.2 mmol.l-1), cortical arousal (% of change: caffeine: 2.51; placebo: -1.96) and heart rate (caffeine: 80.0 +/- 7.2 vs. 172.9 +/- 28.2 bpm; placebo: 79.3 +/- 6.4 vs. 154.0 +/- 26.8 bpm). In addition, higher heart rate values correlated negatively with marksmanship in close quarter combat. We concluded that caffeine intake did not improve the warfighters rifle marksmanship in close quarter combat possibly due to the increase in the physiological response. PMID- 29574608 TI - Fish intake interacts with TM6SF2 gene variant to affect NAFLD risk: results of a case-control study. AB - PURPOSE: Non-alcoholic fatty liver disease (NAFLD) is a complex disease, resulting from a variety of genetic and environmental factors. The aim of this case-control study was to evaluate the effect of selected genetic polymorphisms, nutrition aspects and their interaction on the risk of NAFLD. METHODS: The sample consisted of 134 patients with NAFLD and 217 controls. Disease was diagnosed by liver ultrasound and volunteers were clinically and nutritionally assessed. Food groups were extracted from a 172 food-item FFQ questionnaire. Three genetic polymorphisms were assessed: PNPLA3 rs738409, TM6SF2 rs58542926 and GCKR rs780094. RESULTS: We replicated the effect of previously reported risk factors for NAFLD, such as elevated liver enzymes, obesity and metabolic syndrome. Food groups rich in simple sugars, fat and especially saturated fat were positively associated with NAFLD risk, whereas food groups rich in polyunsaturated fatty acids were reversely associated with the possibility of developing the disease (p < 0.05). Only the PNPLA3 genetic variant was statistically significantly associated with the disease (padditive = 0.015). However, it was found that a one portion increase in fish intake increased the risk of NAFLD in carriers of the risk allele of TM6SF2 rs58542926 polymorphism compared to non-carriers, after adjusting for age, gender, energy intake, pack-years, PAL, TM6SF2 genotype and fish consumption (ORdominant = 1.503, 95% CI 1.094-2.064). CONCLUSIONS: Fish intake exerts an additive effect on NAFLD risk for carriers of the TM6SF2 polymorphism. This novel finding provides further rationale on the need for personalized nutritional advice, based on the genetic background of NAFLD patients. PMID- 29574609 TI - Outcome of immature oocytes collection of 119 cancer patients during ovarian tissue harvesting for fertility preservation. AB - PURPOSE: Few clinical options for fertility preservation are available to females with cancer, and data about clinical outcomes is limited. Potential supplementary approaches to fertility preservation include retrieval of immature oocytes followed by in vitro maturation (IVM) and storage. The aim of this study was to evaluate post-thawing outcomes of immature oocytes collected both by transvaginal aspiration and from excised ovarian tissue. METHODS: We conducted a retrospective cohort study of patients treated in a single tertiary center. We reviewed the records of 119 cancer patients who underwent ovarian tissue cryopreservation and immature oocyte harvesting for fertility preservation. All embryos and oocytes that were frozen and thawed were included in the study. Post-thawing outcomes were evaluated. RESULTS: Thirty-five stored embryos from eight patients were thawed. Twenty-nine embryos survived (82% survival rate) and were transferred. Six oocytes were thawed, two oocytes survived, and no oocytes were fertilized. Only one PCOS patient became pregnant, resulting in the normal delivery of a healthy baby. CONCLUSIONS: Although a relatively high number of mature oocytes and embryos can be stored with the combined procedure, the limited rate of pregnancies represents a poor reproductive outcome. Therefore, this approach should be reserved for special groups with limited options. PMID- 29574610 TI - Platelet response to direct thrombin inhibitor or fondaparinux treatment in patients with suspected heparin-induced thrombocytopenia. AB - Making a definitive diagnosis of heparin-induced thrombocytopenia (HIT) can be problematic. A prompt platelet rise following treatment has been proposed as a "post-test" criterion for diagnosis. However, the platelet response following discontinuation of heparin and initiation of a recommended alternative anticoagulant remains largely undefined and unstudied. This study aimed to characterize platelet response to initial treatment in patients with a low, intermediate, or high likelihood of having HIT. This was a multicenter retrospective cohort study. Patients were over 18 years in age, underwent serologic testing for HIT, and received alternative anticoagulation treatment for HIT. Classification of each patient's likelihood of having HIT was based on an empiric, pre-hoc combination of the 4T score and serology results. The primary outcome for this study was a platelet count response after initiation of direct thrombin inhibitor (DTI) or fondaparinux therapy within 48 h. 124 patients were analyzed. The sensitivity and specificity of having an immediate platelet rise of at least 10,000/uL by day 2 after starting treatment among high-likelihood for HIT patients were 0.71 (95% CI 0.55-0.84) and 0.64 (95% CI 0.5-0.76), respectively. The negative predictive value of no platelet rise was 75.5% (95% CI 0.61-0.86). A prompt platelet count rise may be appropriate to consider along with other known criteria for the clinical diagnosis of HIT. The rise should be immediate following discontinuation of heparin and initiation of recommended treatment, with an upward rise within 48 h. PMID- 29574611 TI - Betting on Life: Associations Between Significant Life Events and Gambling Trajectories Among Gamblers with the Intent to Quit. AB - Considerable evidence has suggested that problem gambling may be transitory and episodic, with gamblers routinely moving in and out of clinical thresholds. Findings in qualitative and quantitative studies have converged on identifying preliminary evidence for the role of life events as motivators and contributing factors for gambling changes over time. The aim of this study was to conduct an exploratory analysis of the relationship between life events, their respective experience as positive or negative, and gambling trajectories among problem gamblers intending to quit. Life event occurrence and ratings as positive or negative, and changes in gambling severity were analyzed over a 12-month period for 204 adult problem gamblers intending to reduce or quit their gambling. Overall, mixed effects models revealed several relationships between life events and both the magnitude and direction of gambling change over time. In particular, gamblers who experienced a greater number of positive events or specific events such as legal events, the adoption/loss of a child, or negative changes to their social relationships, finances, work environments or social/health activities were more likely to exhibit greater gambling reductions over time. Conversely, gamblers who experienced a greater number of negative events, such as family bereavement, the dissolution of a marriage, or negative changes to their residence exhibited smaller gambling reductions or increases in gambling severity. Possible mechanisms which may explain the findings and the importance of examining the subjective experience of life events are discussed. Recommendations for future studies examining associations between life events and gambling trajectories are provided. PMID- 29574612 TI - Effect of BMI on allograft function and survival in pediatric renal transplant recipients. AB - OBJECTIVE: To determine whether pre-transplant body mass index (BMI) affects renal allograft function and survival in pediatric renal transplant recipients. STUDY DESIGN: This is a retrospective cohort study using the Organ Procurement and Transplantation Network data from 2000 to 2013 to compare time to total allograft loss (allograft failure or death), prevalence of delayed graft function, prevalence of acute rejection, and estimated glomerular filtration rate (eGFR) post-transplant in pediatric renal transplant recipients categorized by BMI z-score. RESULTS: A total of 8804 kidney transplant recipients met our inclusion criteria, and of those, 6% were underweight, 14% were overweight, and 17% were obese pre-transplant. The adjusted hazard ratio (HR) for allograft failure was significantly higher for obese recipients compared to normal weight recipients (HR 1.25, 95% CI 1.1, 1.42); for every 1 point increase in BMI z score, there was a 7% increased hazard of allograft failure (HR 1.07; 95% CI 1.03 1.1, p < 0.001). The prevalence of delayed graft function and acute rejection increased with higher BMI z-score category; however, this difference did not reach statistical significance. eGFR at 1 and 5 years post-transplant decreased with higher BMI z-score although it was only statistically significant at 1 year. CONCLUSIONS: Obesity is prevalent in pediatric renal transplant recipients, and obese, but not overweight or underweight, pediatric renal transplant recipients have an increased risk of allograft failure. Implementation of effective obesity interventions in pediatric renal transplant recipients is of critical importance to improve longevity of the renal allograft. PMID- 29574613 TI - Expanding tryptophan-containing cyclodipeptide synthase spectrum by identification of nine members from Streptomyces strains. AB - Cyclodipeptide synthases (CDPSs) comprise normally 200-300 amino acid residues and are mainly found in bacteria. They hijack aminoacyl-tRNAs from the ribosomal machinery for cyclodipeptide formation. In this study, nine new CDPS genes from eight Streptomyces strains were cloned into pET28a vector and expressed in Escherichia coli. Structural elucidation of the isolated products led to the identification of one cyclo-L-Trp-L-Leu, two cyclo-L-Trp-L-Pro, and three cyclo-L Trp-L-Trp synthases. Other three CDPSs produce cyclo-L-Trp-L-Ala or cyclo-L-Trp-L Tyr as the major cyclodipeptide. Total product yields of 46 to 211 mg/L E. coli culture were obtained. Our findings represent rare examples of CDPS family derived from actinobacteria that form various tryptophan-containing cyclodipeptides. Furthermore, this study highlights the potential of the microbial machinery for tryptophan-containing cyclodipeptide biosynthesis and provides valid experimental basis for further combination of these CDPS genes with other modification genes in synthetic biology. PMID- 29574614 TI - Two trehalose-hydrolyzing enzymes from Crenarchaeon Sulfolobus acidocaldarius exhibit distinct activities and affinities toward trehalose. AB - Two archaeal trehalase-like genes, Saci1250 and Saci1816, belonging to glycoside hydrolase family 15 (GH15) from the acidophilic Crenarchaeon Sulfolobus acidocaldarius were expressed in Escherichia coli. The gene products showed trehalose-hydrolyzing activities, and the names SaTreH1 and SaTreH2 were assigned to Saci1816 and Saci1250 gene products, respectively. These newly identified enzymes functioned within a narrow range of acidic pH values at elevated temperatures, which is similar to the behavior of Euryarchaeota Thermoplasma trehalases. SaTreH1 displayed high KM and kcat values, whereas SaTreH2 had lower KM and kcat values despite a high degree of identity in their primary structures. A mutation analysis indicated that two glutamic acid residues in SaTreH1, E374 and E574, may be involved in trehalase catalysis because SaTreH1 E374Q and E574Q showed greatly reduced trehalose-hydrolyzing activities. Additional mutations substituting G573 and H575 residues with serine and glutamic acid residues, respectively, to mimic the TVN1315 sequence resulted in a decrease in trehalase activity and thermal stability. Taken together, the results indicated that Crenarchaea trehalases adopt active site structures that are similar to Euryarchaeota enzymes but have distinct molecular features. The identification of these trehalases could extend our understanding of the relationships between the structure and function of GH15 trehalases as well as other family enzymes and will provide insights into archaeal trehalose metabolism. PMID- 29574615 TI - Enhancement of HIV-1 VLP production using gene inhibition strategies. AB - Gag polyprotein from HIV-1 is able to generate virus-like particles (VLPs) when recombinantly expressed in animal cell platforms. HIV-1 VLP production in HEK293 cells can be improved by the use of different strategies for increasing product titers. One of them is the so-called extended gene expression (EGE), based on repeated medium exchanges and retransfections of the cell culture to prolong the production phase. Another approach is the media supplementation with gene expression enhancers such as valproic acid and caffeine, despite their detrimental effect on cell viability. Valproic acid is a histone deacetylase inhibitor while caffeine has a phosphodiesterase inhibition effect. Here, the combination of the EGE protocol with additive supplementation to maximize VLP production is first tested. As an alternative to the direct additive supplementation, the replacement of these chemical additives by iRNA for obtaining the same inhibition action is also tested. The combination of the EGE protocol with caffeine and valproic acid supplementation resulted in a 1.5-fold improvement in HIV-1 VLP production compared with the EGE protocol alone, representing an overall 18-fold improvement over conventional batch cultivation. shRNAs encoded in the expression vector were tested to substitute valproic acid and caffeine. This novel strategy enhanced VLP production by 2.3 fold without any detrimental effect on cell viability (91.7%) compared with the batch cultivation (92.0%). Finally, the combination of shRNA with EGE resulted in more than 15.6 fold improvement compared with the batch standard protocol traditionally used. The methodology developed enables the production of high titers of HIV-1 VLPs avoiding the toxic effects of additives. PMID- 29574616 TI - Transformation techniques for metabolic engineering of diatoms and haptophytes: current state and prospects. AB - Diatoms and haptophytes represent a key segment of the dominant phytoplankton communities that frequently form massive blooms in the photic zone of the ocean and are considered indicators of global climate changes. Diatoms and haptophytes also play a vital role in the biological carbon fixation in the carbon cycles. Carbon partitioning within diatoms and haptophytes possesses a wide range of chemical compounds and storage materials, such as lipids, carbohydrates, and chlorophyll. Among the marine microorganisms, diatoms and haptophytes have been recognized as promising sources of long- and very long-chain polyunsaturated fatty acids (PUFA). So far, a variety of approaches have been employed for genetic modification in the nuclei of diatoms and haptophytes. Studies on transformation and metabolic engineering in various intracellular genomes, such as chloroplast and mitochondria, are scarce. Particle bombardment, Agrobacterium and PEG-mediated gene transfer, and electroporation have been reported for foreign gene transformation into the diatoms and haptophytes. Antibiotics (G418 and chloramphenicol) and herbicides (zeocin, hygromycin, and norflurazon) have been successfully demonstrated as the best selection markers. Despite the availability of a wide range of molecular tools for foreign gene expression in microalgae, very few promoters (lhcf1, nr, h4, ef2, fcp, and pds) have been reported for diatoms and haptophytes. Therefore, in this review, we first summarize the significant progress that has been achieved in transgene expression in diatoms and haptophytes and highlight the importance and availability of recently developed novel tools that are suitable for transgenic expression in diatoms and haptophytes. PMID- 29574617 TI - Mechanical properties of bio self-healing concrete containing immobilized bacteria with iron oxide nanoparticles. AB - Concrete is arguably one of the most important and widely used materials in the world, responsible for the majority of the industrial revolution due to its unique properties. However, it is susceptible to cracking under internal and external stresses. The generated cracks result in a significant reduction in the concrete lifespan and an increase in maintenance and repair costs. In recent years, the implementation of bacterial-based healing agent in the concrete matrix has emerged as one of the most promising approaches to address the concrete cracking issue. However, the bacterial cells need to be protected from the high pH content of concrete as well as the exerted shear forces during preparation and hardening stages. To address these issues, we propose the magnetic immobilization of bacteria with iron oxide nanoparticles (IONs). In the present study, the effect of the designed bio-agent on mechanical properties of concrete (compressive strength and drying shrinkage) is investigated. The results indicate that the addition of immobilized Bacillus species with IONs in concrete matrix contributes to increasing the compressive strength. Moreover, the precipitates in the bio-concrete specimen were characterized using scanning electron microscope (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDS). The characterization studies confirm that the precipitated crystals in bio concrete specimen were CaCO3, while no precipitation was observed in the control sample. PMID- 29574618 TI - Safety and comfort of domestic bortezomib injection in real-life experience. AB - Despite novel agents, multiple myeloma is still an incurable disease, especially for elderly and frail patients, who are difficult to manage for concomitant comorbidities as the therapeutic options are limited and the response to chemotherapy is often short. We report our evaluations upon safety and efficacy of domestic subcutaneous bortezomib in elderly and frail patients candidate to bortezomib-melphalan-prednisone (VMP) regimen. We confirmed that overall incidence of adverse events, including peripheral neuropathy, was low, and in no case required admission to emergency service, contributing to reduce the rate of therapy discontinuation. These results confirm the effectiveness and safety of subcutaneous bortezomib, in a real-life-experience, and define a new possibility of safe auto-administration in a comfortable domestic setting. We suggest that domestic treatment can significantly improve the quality of life of the patients, avoiding unnecessary transfer to the hospital without reducing treatment efficacy. PMID- 29574619 TI - A qualitative analysis of oncology clinicians' perceptions and barriers for physical activity counseling in breast cancer survivors. AB - BACKGROUND: Few breast cancer survivors (BCS) engage in sufficient physical activity (PA) to gain physical and mental health benefits. This may be due to a lack of appropriate PA information and support. While key messengers of PA information could be oncology clinicians, many do not consistently counsel their patients on PA. PURPOSE: To examine factors affecting PA counseling in clinicians and inform future strategies. METHODS: Focus groups were conducted with clinicians (N = 27) at four cancer hospitals to better understand factors that affect PA counseling. Focus group discussions were transcribed verbatim and analyzed using inductive thematic analysis. RESULTS: Clinicians perceived a lack of training and knowledge related to PA and BCS. Clinicians also discussed being unsure of when to integrate PA counseling into different phases of survivorship. Similarly, clinicians experienced barriers from hospital administration to maintain patient flow in-clinic, which decreased opportunities for PA counseling. Additionally, lack of awareness of community-based programs within large areas served by hospitals also decreased clinicians' self-efficacy for counseling. In order to facilitate PA counseling, clinicians wanted resources that promote patient-managed PA, available on multiple platforms (e.g., printed and online). Continued education, highlighting recent research and effective implementation of PA, was noted as an important facilitator. CONCLUSIONS: Researchers are encouraged to develop research agendas and test educational strategies that are integrated into current practice, empirically test barriers that developed from this study with a larger, representative sample to determine salient barriers and develop PA counseling strategies that are clinician-initiated but not dependent on clinicians.

AB - In this study, we propose to develop a geostatistical computational framework to model the distribution of rat bite infestation of epidemic proportion in Peshawar valley, Pakistan. Two species Rattus norvegicus and Rattus rattus are suspected to spread the infestation. The framework combines strengths of maximum entropy algorithm and binomial kriging with logistic regression to spatially model the distribution of infestation and to determine the individual role of environmental predictors in modeling the distribution trends. Our results demonstrate the significance of a number of social and environmental factors in rat infestations such as (I) high human population density; (II) greater dispersal ability of rodents due to the availability of better connectivity routes such as roads, and (III) temperature and precipitation influencing rodent fecundity and life cycle.

AB - INTRODUCTION: In patients with rheumatoid arthritis (RA), combination treatment with methotrexate (MTX) and adalimumab is more effective than MTX monotherapy. From the patients' perspective, the impact of reduced MTX doses upon initiating adalimumab is not known. The objective was to evaluate the effects of low and high MTX doses in combination with adalimumab initiation on patient-reported outcomes (PROs), in MTX-inadequate responders (MTX-IR) with moderate-to-severe RA. METHODS: MUSICA was a randomized, double-blind, controlled trial evaluating the efficacy of 7.5 or 20 mg/week MTX, in combination with adalimumab for 24 weeks in MTX-IR RA patients receiving prior MTX >= 15 mg/week for >= 12 weeks. PROs were recorded at each visit, including physical function, health-related quality-of-life, work productivity, quality-of-sleep, satisfaction with treatment medication, sexual impairment due to RA, patient global assessment of disease activity (PGA), and patient pain. Last observation carried forward was used to account for missing values. RESULTS: At baseline, patients in both MTX dosage groups had similar demographics, disease characteristics, and PRO scores. Overall, initiation of adalimumab led to significant improvements from baseline in the PROs assessed for both MTX dosage groups. Improvements in presenteeism from baseline were strongly correlated with corresponding improvements in SF-36 (vitality), pain, and physical function. Physical and mental well-being had a good correlation with improvement in sleep. Overall, improvements in disease activity from baseline were correlated with improvements in several PROs. CONCLUSIONS: The addition of adalimumab to MTX in MTX-IR patients with moderate to-severe RA led to improvements in physical function, quality-of-life, work productivity, quality of sleep, satisfaction with treatment medication, and sexual impairment due to RA, regardless of the concomitant MTX dosage.

AB - Cytochrome c is known as an electron-carrying protein in the respiratory chain of mitochondria. Over the last 20 years, however, alternative functions of this very versatile protein have become the focus of research interests. Upon binding to anionic lipids such as cardiolipin, the protein acquires peroxidase activity. Multiple lines of evidence suggest that this requires a conformational change of the protein which involves partial unfolding of its tertiary structure. This review summarizes the current state of knowledge of how cytochrome c interacts with cardiolipin-containing surfaces and how this affects its structure and function. In this context, we delineate partially conflicting results regarding the affinity of cytochrome c binding to cardiolipin-containing liposomes of different size and its influence on the structure of the protein and the morphology of the membrane. PMID- 29574623 TI - Genetic Risk Prediction for Primary and Secondary Prevention of Atherosclerotic Cardiovascular Disease: an Update. AB - PURPOSE OF REVIEW: This review aims to summarize the research on genetic risk scores and their ability to improve risk prediction in both a primary and a secondary prevention population. RECENT FINDINGS: Several groups have examined the role of genetic scores in different patient populations. Recent studies have capitalized on the growing number of identified genetic variants to construct polygenic risk scores that include hundreds and sometimes thousands of SNPs. Also, recent studies have demonstrated that individuals with high genetic risk scores can attenuate their risk with lifestyle modifications and with statins, for which the benefit of treatment may be greater in those at highest genetic risk. Genetic risk scores when added to existing clinical models appear to improve risk prediction, particularly in the setting of incident cardiovascular disease and may provide actionable information to optimize prevention early in life. Future research will need to establish how to best use this genetic risk information either as a means to further individualize treatment decisions or to better identify high-risk populations. PMID- 29574624 TI - Mitochondrial POLG related disorder presenting prenatally with fetal cerebellar growth arrest. AB - We report the prenatal findings of severe cerebellar growth arrest in two siblings with POLG1 mutations. The first presented with seizures and lactic acidosis immediately after premature birth and was diagnosed with mitochondrial disease on muscle biopsy. Molecular DNA analysis confirmed homozygous missense mutation in the POLG1 gene. The pregnancy of the second sibling was monitored closely by repeat fetal ultrasounds since the parents declined invasive testing. A detailed fetal ultrasound at 19 weeks gestation showed a small cerebellum with transcerebellar diameter (TCD) on axial cranial imaging, measuring below the 5th centile for gestational age. Molecular analysis confirmed the same homozygous familial mutation in the POLG1gene. This report further delineates the phenotypic features of the POLG related disorders and expands it to the prenatal era. Subsequent pregnancies were monitored by molecular analysis, using chorionic villus sampling (CVS).

AB - Tumorigenic cell lines are more susceptible to [Re6Se8I6]3- cluster-induced death than normal cells, becoming a novel candidate for cancer treatment. Still, the feasibility of using this type of molecules in human patients remains unclear and further pharmacokinetics analysis is needed. Using coupled plasma optical emission spectroscopy, we determined the Re-cluster tissue content in injected mice, as a biodistribution measurement. Our results show that the Re-cluster successfully reaches different tissues, accumulating mainly in heart and liver. In order to dissect the mechanism underlying cluster biodistribution, we used three different experimental approaches. First, we evaluate the degree of lipophilicity by determining the octanol/water partition coefficient. The cluster mostly remained in the octanol fraction, with a coefficient of 1.86 +/- 0.02, which indicates it could potentially cross cell membranes. Then, we measured the biological membrane penetration through a parallel artificial membrane permeability assays (PAMPA) assay. The Re-cluster crosses the artificial membrane, with a coefficient of 122 nm/s that is considered highly permeable. To evaluate a potential application of the Re-cluster in central nervous system (CNS) tumors, we analyzed the cluster's brain penetration by exposing cultured blood-brain-barrier (BBB) cells to increasing concentrations of the cluster. The Re-cluster effectively penetrates the BBB, reaching nearly 30% of the brain side after 24 h. Thus, our results indicate that the Re-cluster penetrates biological membranes reaching different target organs-most probably due to its lipophilic properties-becoming a promising anti-cancer drug with high potential for CNS cancer's diagnosis and treatment. PMID- 29574626 TI - Cardiac computed tomography compared with two-dimensional transesophageal echocardiography for the detection and assessment of atrial septal pouches. AB - The aim of this study is to compare the two-dimensional transesophageal echocardiography (2D-TEE) with multi-slice computed tomography (MSCT) and with autopsied material to evaluate the ability and precision of the imaging methods for the detection and assessment of septal pouch (SP). One hundred and fifty patients that underwent both 2D-TEE and MSCT and 50 autopsied human hearts were investigated. In MSCT, the interatrial septum was classified as a left SP in 37.3%, right SP in 3.3%, and patent foramen ovale (PFO) channel in 3.3%. In 2D TEE, the interatrial septum was classified as a left SP in 39.3%, right SP in 11.3%, double SP in 4.7%, and PFO channel in 2.0%. The weighted kappa coefficient between MSCT and 2D-TEE in assessing the septum morphology was 0.59. The prevalence of the left SP is lower when it is evaluated by MSCT or 2D-TEE than by anatomical study, but this difference is insignificant (37.3% vs. 44.0%, p = 0.40, and 39.3% vs. 44.0%, p = 0.56, respectively). The prevalence of left SPs is lower when detected by MSCT or 2D-TEE than during autopsy, but the difference is statistically insignificant (37.3% vs. 44.0%, p = 0.40, and 39.3% vs. 44.0%, p = 0.56, respectively). Both 2D-TEE and MSCT are comparable techniques for detecting left-sided SPs with the insignificant lower prevalence of detecting left-sided SPs compared to autopsied material. However, TEE with the contrast seems to be superior over MSCT due to the possibility of unambiguous PFO channel detection. Therefore, TEE with contrast should be preferred over MSCT in the identification of left-sided SPs.

AB - PURPOSE: This study aimed to estimate the validity and applicability of Vela laser enucleation of the prostate (VoLEP) in the management of benign prostatic hyperplasia (BPH). METHODS: A retrospective chart review of 112 patients with BPH who underwent VoLEP (n = 60) or holmium laser enucleation of the prostate (HoLEP) (n = 56) was conducted at our institution from January 2015 to June 2015. The general and perioperative characteristics of the patients were collected. The 12 month follow-up data, including the lower urinary tract symptom (LUTS) indexes (International Prostate Symptom Score [I-PSS], quality-of-life [QoL] score and maximum flow rate [Qmax]), as well as rates of perioperative and late complications, were analyzed. RESULTS: No significant differences were observed in pre- and perioperative parameters, including operation time (58.05 +/- 10.14 vs. 60.14 +/- 12.30 min, P = 0.44), serum sodium decrease (3.49 +/- 0.83 vs. 3.48 +/- 0.84 mmol/L, P = 0.97), hemoglobin decrease (1.28 +/- 0.38 vs. 1.24 +/- 0.77 g/dL, P = 0.71), catheterization time (3.63 +/- 1.10 vs. 3.89 +/- 1.11 days, P = 0.21) and hospital stay (4.57 +/- 1.25 vs. 4.68 +/- 1.18 days, P = 0.63) between the two groups of patients. Compared with the HoLEP group, the noise during operation was lower in VoLEP group (47.22 +/- 10.31 vs. 59.45 +/- 9.65 db, P < 0.05). During 1, 6 and 12 months of follow-up visits, the LUTS indexes (I-PSS, QoL score and Qmax) were remarkably improved in both groups when comparing with the baseline values. Furthermore, LUTS indexes were comparable in both groups (P > 0.05). CONCLUSION: Similarly as the holmium laser, the Vela laser is a potent, safe, efficient durable and surgical treatment option for minimally invasive surgery in patients with BPH-induced LUTS. PMID- 29574628 TI - Amyloid-beta Increases Tau by Mediating Sirtuin 3 in Alzheimer's Disease. AB - Increasing evidence indicates that sirtuin 3 (Sirt3) has neuroprotective effects in regulating oxidative stress and energy metabolism, both of which are involved in the pathogenesis of Alzheimer's disease (AD). However, it is unclear whether Sirt3 is associated with cognitive performance and pathological changes in AD. We conducted a case-control study of the postmortem brains of AD (n = 16), mild cognitive impairment (n = 13), and age- and education-matched cognitively normal (CN, n = 11) subjects. We measured the mRNA and protein levels of Sirt3 and assessed their association with cognitive performance and AD pathology. In an ex vivo model of cortical neurons from transgenic mice that carry human tau protein, we modified Sirt3 expression by genetic knockdown and knock-in to investigate the cause-effect relationship between Sirt3 and tau. Sirt3 levels were reduced in the entorhinal cortex, the middle temporal gyrus, and the superior frontal gyrus of AD subjects compared to those of CN. This reduction was associated with poorer test scores of neuropsychological evaluation and the severity of tau pathology. Further study with genetic manipulation of Sirt3 revealed that amyloid-beta increased levels of total tau acetylated tau through its modulation of Sirt3. These data suggest that reduction of Sirt3 is critically involved in pathogenesis of AD. PMID- 29574629 TI - Exercise Rehabilitation Attenuates Cognitive Deficits in Rats with Traumatic Brain Injury by Stimulating the Cerebral HSP20/BDNF/TrkB Signalling Axis. AB - Physical exercise (PE) is an effective method for improving cognitive function among patients with traumatic brain injury (TBI). We previously demonstrated that PE with an infrared-sensing running wheel (ISRW) system provides strong neuroprotection in an experimental animal model of stroke. In this study, we used fluid percussion injury in rats to simulate mild TBI. For rats, we used both passive avoidance learning and the Y-maze tests to evaluate cognitive function. We investigated whether PE rehabilitation attenuated cognitive deficits in rats with TBI and determined the contribution of hippocampal and cortical expression of heat shock protein 20 (HSP20) to PE-mediated cognitive recovery. In addition to increasing hippocampal and cortical expression of HSP20, brain-derived neurotrophic factor (BDNF), and the tropomyosin receptor kinase B (TrkB) ratio, PE rehabilitation significantly attenuated brain contusion and improved cognitive deficits in the rat model. Furthermore, reducing hippocampal and cortical expression of HSP20 with an intracerebral injection of pSUPER hsp20 small interfering RNA significantly diminished the PE-induced overexpression of hippocampal and cortical BDNF and the TrkB ratio and also reversed the beneficial effect of PE in reducing neurotrauma and the cognitive deficits. A positive Pearson correlation was found between HSP20 and BDNF, as well as between HSP20 and TrkB, in the hippocampal and cortical tissues. We thus conclude that post ischaemic ISRW exercise rehabilitation attenuates cognitive deficits, as well as brain contusions, in TBI rats by stimulating the cerebral HSP20/BDNF/TrkB signalling axis. PMID- 29574630 TI - P2Y12 but not P2Y13 Purinergic Receptor Controls Postnatal Rat Retinogenesis In Vivo. AB - Adenine nucleotides through P2Y1 receptor stimulation are known to control retinal progenitor cell (RPC) proliferation by modulating expression of the p57KIP2, a cell cycle regulator. However, the role of Gi protein-coupled P2Y12 and P2Y13 receptors also activated by adenine nucleotides in RPC proliferation is still unknown. Gene expression of the purinergic P2Y12 subtype was detected in rat retina during early postnatal days (P0 to P5), while expression levels of P2Y13 were low. Immunohistochemistry assays performed with rat retina on P3 revealed P2Y12 receptor expression in both Ki-67-positive cells in the neuroblastic layer and Ki-67-negative cells in the ganglion cell layer and inner nuclear layer. Nonetheless, P2Y13 receptor expression could not be detected in any stratum of rat retina. Intravitreal injection of PSB 0739 or clopidogrel, both selective P2Y12 receptor antagonists, increased by 20 and 15%, respectively, the number of Ki-67-positive cells following 24 h of exposure. Moreover, the P2Y12 receptor inhibition increased cyclin D1 and decreased p57KIP2 expression. However, there were no changes in the S phase of the cell cycle (BrdU-positive cells) or in mitosis (phospho-histone-H3-positive cells). Interestingly, an increase in the number of cyclin D1/TUNEL-positive cells after treatment with PSB 0739 was observed. These data suggest that activation of P2Y12 receptors is required for the successful exit of RPCs from cell cycle in the postnatal rat retina. PMID- 29574632 TI - An integrate-and-fire model to generate spike trains with long-range dependence. AB - Long-range dependence (LRD) has been observed in a variety of phenomena in nature, and for several years also in the spiking activity of neurons. Often, this is interpreted as originating from a non-Markovian system. Here we show that a purely Markovian integrate-and-fire (IF) model, with a noisy slow adaptation term, can generate interspike intervals (ISIs) that appear as having LRD. However a proper analysis shows that this is not the case asymptotically. For comparison, we also consider a new model of individual IF neuron with fractional (non Markovian) noise. The correlations of its spike trains are studied and proven to have LRD, unlike classical IF models. On the other hand, to correctly measure long-range dependence, it is usually necessary to know if the data are stationary. Thus, a methodology to evaluate stationarity of the ISIs is presented and applied to the various IF models. We explain that Markovian IF models may seem to have LRD because of non-stationarities. PMID- 29574631 TI - Oxidative stress as a possible mechanism of statin-induced myopathy. AB - Statins, inhibitors of hydroxy methyl glutaryl coenzyme-A (HMG-CoA) reductase, are the most widely used drugs for treating hypercholesterolemia. However, statins can cause disabling myopathy as their main adverse effect. Several molecular mechanisms underlie the statin-induced myopathy including the decrease in the levels of essential mevalonate and cholesterol derivatives. This review discusses a further mechanism involving the loss of other anti-oxidant defenses besides ubiquinone (Co-Q) in skeletal muscles which produce a significant amount of reactive oxygen species (ROS). Therefore, to maintain their function, skeletal muscles need a high level of anti-oxidants. PMID- 29574633 TI - A Network Meta-Analysis Comparing Semaglutide Once-Weekly with Other GLP-1 Receptor Agonists in Japanese Patients with Type 2 Diabetes. AB - INTRODUCTION: Semaglutide once-weekly (QW) is a novel glucagon-like peptide-1 (GLP-1) analogue administered at a 0.5 or 1.0 mg dose. In the absence of head-to head trials between semaglutide QW and other GLP-1 receptor agonists (GLP-1 RAs) in a Japanese population, a network meta-analysis (NMA) was performed. The objective was to assess the relative efficacy and safety of semaglutide QW vs GLP 1 RAs in Japanese patients with type 2 diabetes (T2DM), with a specific focus on the comparison between semaglutide 0.5 mg QW and dulaglutide 0.75 mg QW. METHODS: A systematic review (SR) and supplementary Japanese searches were conducted to identify trials of GLP-1 RAs in Japanese patients on diet and exercise, who have previously received 0-1 oral antidiabetic drugs (OADs). Data at 52-56 weeks were extracted for the following outcomes (feasible for analysis in an NMA): glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), weight, systolic blood pressure (SBP), and overall hypoglycemia. The data were synthesized using an NMA and a Bayesian framework. RESULTS: Four trials, identified from the SR and Japanese specific searches, were relevant for inclusion in the NMA. When compared to dulaglutide 0.75 mg QW, semaglutide 0.5 mg QW was shown to provide significant reductions in HbA1c [- 0.61% (12.3 mmol/mol)], weight (- 1.45 kg), SBP (- 5.03 mmHg), and FPG (- 1.26 mmol/L). No significant differences in the proportion of patients achieving a HbA1c level < 7% (53 mmol/mol) or the risk of overall hypoglycemia were observed between semaglutide 0.5 mg QW and dulaglutide 0.75 mg QW. CONCLUSION: Overall, semaglutide 0.5 mg QW was associated with significant reductions from baseline in HbA1c, weight, SBP, and FPG compared with dulaglutide 0.75 mg QW in Japanese patients with T2DM. These data may provide valuable evidence for clinical decision-making, cost-effectiveness analyses, and health technology appraisal (HTA) requirements. FUNDING: Novo Nordisk Pharma Ltd. PMID- 29574634 TI - Basal Insulin Intensification in Patients with Type 2 Diabetes: A Review. AB - : As the number of people living with type 2 diabetes (T2D) continues to rise, managing their complex needs presents an increasing challenge to physicians. While treatment guidelines provide evidence-based guidance, they are not prescriptive-rather they emphasize individualization of management based on a patient's clinical needs and preferences. Physicians, therefore, need to be fully aware of the advantages and disadvantages of the multiple and increasing treatment options available to them at each stage of the disease. The progressive nature of T2D means that treatment with basal insulin will become inevitable for many patients, while for some patients basal insulin alone will eventually be insufficient for maintaining glycemic targets. Recent guidelines recommend two basic approaches for intensifying basal insulin: the use of rapid-acting insulin, either as additional prandial injections or as part of premix (biphasic) insulin; and the addition of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) to the insulin therapy, which can be administered via subcutaneous injection once or twice daily, or weekly depending on formulation. More recently, two fixed-ratio combinations of basal insulin and a GLP-1 RA that allow for once-daily dosing have been approved. Each of these approaches has potential benefits and drawbacks, particularly in terms of risk for hypoglycemia, weight change, convenience, and side effects. Understanding these differences is central to guiding patient and physician choice. This article discusses the rationale, advantages, disadvantages, and implementation of currently available strategies for basal insulin treatment intensification in patients with T2D.

AB - INTRODUCTION: Few prospective clinical trials have investigated the role of fasting blood glucose (FBG) and/or postprandial glucose (PPG) in assessing overall glycemic control by using different insulin regimens. In the present post hoc analysis, we assessed the contribution of FBG and/or PPG in overall glycemic control in Chinese patients under insulin treatment. METHODS: CLASSIFY is a phase IV, randomized, open-label, 26-week, parallel-arm, treat-to-target, multinational, controlled study in patients with type 2 diabetes mellitus to compare the efficacy and safety of insulin lispro mix 25 (LM25) and insulin lispro mix 50 (LM50) as starter insulins. Insulin was titrated with an aim to target pre-meal blood glucose (BG) levels at > 3.9 and <= 6.1 mmol/L before breakfast and dinner. The primary outcome assessed was the change in HbA1c from baseline. RESULTS: Chinese patients contributed 38.7% (N = 156) of the total population. The majority of patients were male (52.6%). The mean (SD) body mass index was 24.54 (3.04) kg/m2 and mean (SD) HbA1c was 8.54 (1.10) % at baseline. At week 26, LM50 showed a significantly greater reduction from baseline in HbA1c (- 2.03% vs - 1.55%, P < 0.001), average daily BG (- 3.21 vs - 2.34 mmol/L, P < 0.001), average post-meal BG (- 3.58 vs - 2.39 mmol/L, P < 0.001), and average prandial BG excursion (- 1.01 vs - 0.22 mmol/L, P = 0.006) than the LM25 group. The reductions in average pre-meal BG (- 2.59 vs - 2.28 mmol/L, P = 0.137) were not significantly different between the groups. The proportion of patients achieving HbA1c targets (< 7% or <= 6.5%) without nocturnal hypoglycemia or weight gain was greater (P < 0.05) with LM50 compared with LM25. CONCLUSION: LM50 achieved better overall glycemic control than LM25 as a starter insulin in Chinese patients, which may be due to greater improvement in PPG levels.

PMID- 29574636 TI - GPCRs profiling and identification of GPR110 as a potential new target in HER2+ breast cancer. AB - PURPOSE: G protein-coupled receptors (GPCRs) represent the largest family of druggable targets in human genome. Although several GPCRs can cross-talk with the human epidermal growth factor receptors (HERs), the expression and function of most GPCRs remain unknown in HER2+ breast cancer (BC). In this study, we aimed to evaluate gene expression of GPCRs in tumorigenic or anti-HER2 drug-resistant cells and to understand the potential role of candidate GPCRs in HER2+ BC. METHODS: Gene expression of 352 GPCRs was profiled in Aldeflur+ tumorigenic versus Aldeflur- population and anti-HER2 therapy-resistant derivatives versus parental cells of HER2+ BT474 cells. The GPCR candidates were confirmed in 7 additional HER2+ BC cell line models and publicly available patient dataset. Anchorage-dependent and anchorage-independent cell growth, mammosphere formation, and migration/invasion were evaluated upon GPR110 knockdown by siRNA in BT474 and SKBR3 parental and lapatinib+ trastuzumab-resistant (LTR) cells. RESULTS: Adhesion and class A GPCRs were overexpressed in Aldeflur+ and anti-HER2 therapy resistant population of BT474 cells, respectively. GPR110 was the only GPCR overexpressed in Aldeflur+ and anti-HER2 therapy-resistant population in BT474, SKBR3, HCC1569, MDA-MB-361, AU565, and/or HCC202 cells and in HER2+ BC subtype in patient tumors. Using BT474 and SKBR3 parental and LTR cells, we found that GPR110 knockdown significantly reduced anchorage-dependent/independent cell growth as well as migration/invasion of parental and LTR cells and mammosphere formation in LTR derivatives and not in parental cells. CONCLUSION: Our data suggest a potential role of GPR110 in tumorigenicity and in tumor cell dissemination in HER2+ BC. PMID- 29574637 TI - Validation of a personalized risk prediction model for contralateral breast cancer. AB - PURPOSE: Women diagnosed with unilateral breast cancer are increasingly choosing to remove their other unaffected breast through contralateral prophylactic mastectomy (CPM) to reduce the risk of contralateral breast cancer (CBC). Yet a large proportion of CPMs are believed to be medically unnecessary. Thus, there is a pressing need to educate patients effectively on their CBC risk. We had earlier developed a CBC risk prediction model called CBCRisk based on eight personal risk factors. METHODS: In this study, we validate CBCRisk on independent clinical data from the Johns Hopkins University (JH) and MD Anderson Cancer Center (MDA). Women whose first breast cancer diagnosis was either invasive and/or ductal carcinoma in situ and whose age at first diagnosis was between 18 and 88 years were included in the cohorts because CBCRisk was developed specifically for these women. A woman who develops CBC is called a case whereas a woman who does not is called a control. The cohort sizes are 6035 (with 117 CBC cases) for JH and 5185 (with 111 CBC cases) for MDA. We computed the relevant calibration and validation measures for 3- and 5-year risk predictions. RESULTS: We found that the model performs reasonably well for both cohorts. In particular, area under the receiver operating characteristic curve for the two cohorts range from 0.61 to 0.65. CONCLUSIONS: With this independent validation, CBCRisk can be used confidently in clinical settings for counseling BC patients by providing their individualized CBC risk. In turn, this may potentially help alleviate the rate of medically unnecessary CPMs. PMID- 29574638 TI - Long-Chain Omega-3 Polyunsaturated Fatty Acids Modulate Mammary Gland Composition and Inflammation. AB - Studies in rodents have shown that dietary modifications as mammary glands (MG) develop, regulates susceptibility to mammary tumor initiation. However, the effects of dietary PUFA composition on MGs in adult life, remains poorly understood. This study investigated morphological alterations and inflammatory microenvironments in the MGs of adult mice fed isocaloric and isolipidic liquid diets with varying compositions of omega (omega)-6 and long-chain (Lc)-omega3FA that were pair-fed. Despite similar consumption levels of the diets, mice fed the omega-3 diet had significantly lower body-weight gains, and abdominal-fat and mammary fat pad (MFP) weights. Fatty acid analysis showed significantly higher levels of Lc-omega-3FAs in the MFPs of mice on the omega-3 diet, while in the MFPs from the omega-6 group, Lc-omega-3FAs were undetectable. Our study revealed that MGs from omega-3 group had a significantly lower ductal end-point density, branching density, an absence of ductal sprouts, a thinner ductal stroma, fewer proliferating epithelial cells and a lower transcription levels of estrogen receptor 1 and amphiregulin. An analysis of the MFP and abdominal-fat showed significantly smaller adipocytes in the omega-3 group, which was accompanied by lower transcription levels of leptin, IGF1, and IGF1R. Further, MFPs from the omega-3 group had significantly decreased numbers and sizes of crown-like structures (CLS), F4/80+ macrophages and decreased expression of proinflammatory mediators including Ptgs2, IL6, CCL2, TNFalpha, NFkappaB, and IFNgamma. Together, these results support dietary Lc-omega-3FA regulation of MG structure and density and adipose tissue inflammation with the potential for dietary Lc-omega-3FA to decrease the risk of mammary gland tumor formation. PMID- 29574639 TI - Toxicity evaluation of 4,4'-di-CDPS and 4,4'-di-CDE on green algae Scenedesmus obliquus: growth inhibition, change in pigment content, and oxidative stress. AB - Polychlorinated diphenyl sulfides and polychlorinated diphenyl ethers are two types of dioxin-like pollutants, which are prevalent in aquatic environments. However, to date, limited information is available regarding their toxicity to green algae. In this study, growth inhibition, effect on pigment content, and oxidative stress potentials of 4,4'-di-CDPS and 4,4'-di-CDE on green algae Scenedesmus obliquus were investigated. The results indicate that the EC50 values of 4,4'-di-CDPS after 24, 48, 72, and 96 h of exposure were 1.736, 1.172, 0.994, and 0.820 mg/L, while the corresponding values for 4,4'-di-CDE were 0.697, 1.087, 0.833, and 0.327 mg/L. As compared to the control group, most of the measured pigment content in algal cells significantly decreased after 96-h exposure to these two chemicals, suggesting their suppressive capability on the photosynthesis process in algal cells. Additionally, oxidative stress occurred as demonstrated by the significantly inhibited activities of the antioxidant enzymes (total superoxide dismutase (T-SOD), catalase (CAT), and glutathione peroxidase (GPx)), and high increases in malondialdehyde (MDA) content in all 4,4'-di-CDE treated groups and some moderate-dose and high-dose treatments with 4,4'-di-CDPS. Acute toxicity tests and biochemical analysis showed that 4,4'-di-CDE was more toxic than 4,4'-di-CDPS on S. obliquus.

AB - The silicon oil-air partition coefficients (KSiO/A) of hydrophobic compounds are vital parameters for applying silicone oil as non-aqueous-phase liquid in partitioning bioreactors. Due to the limited number of KSiO/A values determined by experiment for hydrophobic compounds, there is an urgent need to model the KSiO/A values for unknown chemicals. In the present study, we developed a universal quantitative structure-activity relationship (QSAR) model using a sequential approach with macro-constitutional and micromolecular descriptors for silicone oil-air partition coefficients (KSiO/A) of hydrophobic compounds with large structural variance. The geometry optimization and vibrational frequencies of each chemical were calculated using the hybrid density functional theory at the B3LYP/6-311G** level. Several quantum chemical parameters that reflect various intermolecular interactions as well as hydrophobicity were selected to develop QSAR model. The result indicates that a regression model derived from logKSiO/A, the number of non-hydrogen atoms (#nonHatoms) and energy gap of ELUMO and EHOMO (ELUMO-EHOMO) could explain the partitioning mechanism of hydrophobic compounds between silicone oil and air. The correlation coefficient R2 of the model is 0.922, and the internal and external validation coefficient, Q2LOO and Q2ext , are 0.91 and 0.89 respectively, implying that the model has satisfactory goodness-of-fit, robustness, and predictive ability and thus provides a robust predictive tool to estimate the logKSiO/A values for chemicals in application domain. The applicability domain of the model was visualized by the Williams plot.

AB - A novel adsorbent, three-dimensional porous graphene/lignin/sodium alginate nanocomposite (denoted as 3D PG/L/SA) was fabricated by hydrothermal polymerization of lignin and sodium alginate in the presence of graphene oxide (GO) in an aqueous system. Fourier transform infrared spectra, thermo-gravimetric analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy were employed to characterize the morphology and structure of this novel functional PG/L/SA nanocomposite. A series of adsorption experiments for cleanup of Cd(II) and Pb(II) were conducted to investigate the effects of lignin and sodium alginate on the graphene structure. It was found that PG/L/SA showed a significant increase in adsorption capacity contrast to porous graphene (PG). The as-prepared material achieved the adsorption capacity for Cd(II) and Pb(II) of 79.88 and 226.24 mg/g, respectively. Meanwhile, the adsorption process matched well with the Langmuir isotherm model and the pseudo-second-order kinetic model. Studies were also conducted to demonstrate the applicability of the sorbent to the removal of heavy metal ions from metal smelting wastewater.

AB - The photocatalytic mineralization efficiency of volatile organic compounds (VOCs) is determined by adsorption of reactants, separation of charge carriers, and reaction activity of catalyst surface. Herein, we provide a strategy to synthesize a novel catalyst, namely, PhPt-Micro, which is characterized by high adsorption ability, charge separation efficiency, and surface reaction activity. Toluene was chosen as the model VOC. The effects of photochemical deposition of Pt on the physical properties of microporous amorphous TiO2 (Micro) and toluene mineralization were studied using N2 adsorption/desorption, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, GC-flame ionization detection, and surface photovoltage spectroscopy (SPS) analyses. After photochemical treatment, the structure of Micro was optimized, and Pt nanoparticles were successfully deposited at the outlet of electrons on the catalyst surface. SPS result proved that the optimized structure enhanced the separation efficiency of charge carriers and the migration of photo-generated electrons to the PhPt-Micro surface. The quasi-equilibrium adsorption amount of toluene over PhPt-Micro was two times higher than that with commercial nano TiO2 (P25). The micropores concentrated toluene on the catalyst surface and hindered intermediate desorption. The mineralization efficiency of toluene over PhPt-Micro was 2.4 and 5.9 times higher than those over Micro and P25, respectively.

AB - The peach fruit fly (PFF), Bactrocera zonata, is a serious insect pest infesting fruits and vegetables. The insecticidal activity of three monoterpenes, namely, (R)-camphor, (R)-carvone, and (1R,2S,5R)-menthol, was evaluated on the second instar larvae of B. zonata. In addition, the latent effects of monoterpenes on pupation, adult emergence, deformation, oviposition, adult longevity, and ovarian development were also examined. The three tested monoterpenes showed pronounced insecticidal activity against B. zonata larvae with (R)-carvone being the most potent toxicant. When the second-instar larvae of B. zonata were treated with monoterpenes at concentrations of 20, 50, and 70 mg/kg for 72 h, significant reduction in pupation and adult emergence was observed. The three monoterpenes caused complete suppression of adult emergence at 100 mg/kg. Moreover, monoterpenes induced complete inhibition of egg deposition at all tested concentrations. Some adult deformations were also noticed at 20, 50, and 70 mg/kg. However, (R)-carvone was more effective than (1R,2S,5R)-menthol and (R) camphor on the examined biological parameters. On the other hand, histological examination of the ovaries of emerged females from larvae that fed on diet treated with (R)-carvone, (1R,2S,5R)-menthol, and (R)-camphor at 20 and 50 mg/L indicated that both concentrations caused retardation in the development of ovarioles. It is clear that all the egg chambers are empty; the germarium region is constricted at base due to the failure of oocyte formation. Many vacant spaces were present between ovarioles. PMID- 29574644 TI - Characteristics of arsenic in humic substances extracted from natural organic sediments. AB - The stability and dispersion of naturally occurring As have been receiving increasing attention, because As is toxic and its contamination is a widespread problem in many countries. This study investigated As fractionation and speciation in organic sediments collected from different depositional settings to elucidate the existence of stable As in humic substances. Eleven organic sediment samples were collected from marine and terrestrial alluvial regions in Hokkaido prefecture, Japan, and the chemical fraction of As and species of humic substances were identified by sequential extraction. In addition, stable As bound in organic matter was evaluated by FT-IR spectroscopy. The As fraction mainly comprised inorganic substances, especially sulfur, iron, and manganese, and terrestrial sediments (lacustrine and inland deposits) were rich in sulfides and Fe and Al (hydr)oxides. When the residual fraction was excluded, the organic fraction of As was higher in seawater sediments than in terrestrial sediments. Among humic substances, cellulose, humic acid, and hydrophilic fulvic acid were clearly associated with As accumulation, and As speciation showed that the As was of organic origin. Cellulose, an organic compound of plant origin, was abundant in As=S and As (III)=O bonds, and As accumulation was higher in sulfur-rich peat sediments, corresponding with the physiological activities of As in plants. Hydrophilic fulvic acid and humic acid in these sediments, originating from small animals and microorganisms in addition to plants, denote higher As contents and abound in As (III, V)=C and C-H, CH3 bonds even in sulfur-rich sediments. The methylated As bonds reflect the ecological transition of organisms.

AB - Asbestos is an environmental carcinogen, and asbestos-related diseases are a global-scale public health issue. We report three cases (one male and two females) of pleural malignant mesothelioma (PMM) caused by environmental asbestos exposure reported by the Apulia Regional Operating Centre (COR) to the National Mesothelioma Registry (ReNaM). The patients revealed no history of asbestos exposure even after detailed assessment. The environmental (neighborhood) asbestos exposure for each of the three cases was due to both the residential history of the subjects and their workplace, close to a military barracks, at a distance of between 45 and 100 m. Moreover, in addition to this new source of pollution, an asbestos cement factory was located in the urban area of Bari municipality, in the Apulia region, southern Italy. Environmental residential/neighborhood asbestos exposure in the city of Bari, a contaminated area classified as a site of national concern for land reclamation, is discussed also with reference to the military barracks. PMID- 29574646 TI - Aliphatic and aromatic biomarkers for fingerprinting of weathered chemically dispersed oil. AB - This study evaluated the applicability of eight types of biomarkers namely, adamantanes, diamantanes, sesquiterpanes, steranes, terpanes, TA-steranes, MA steranes, and alkylated PAHs, to characterize chemically dispersed oil (CDO) after the 60-day weathering. The stability of diagnostic ratios of the selected biomarkers was evaluated and summarized. The results indicated that the concentrations of biomarkers with low molecular weight, such as adamantanes, diamantanes, and sesquiterpanes, in CDO were markedly affected by weathering and the associated diagnostic ratios were changed extensively. Most of the alkylated PAHs were degraded during weathering as well. These biomarkers thus were not recommended for characterizing CDO. The majority of the terpanes, steranes, TA steranes, and MA-steranes could be used for weathered CDO fingerprinting due to the relatively stable diagnostic ratios. The findings could help to identify applicable biomarkers for fingerprinting of weathered dispersed oil. PMID- 29574647 TI - Fine particulate matter (PM2.5) in a compost facility: heavy metal contaminations and health risk assessment, Tehran, Iran. AB - The aim of this study was to evaluate the concentration of PM2.5 particles, potential sources, and determination of health risk assessment of heavy metals in various parts of composting facilities of Tehran's Kahrizak. A total of 60 PM2.5 particle samples were collected every 3 days from January to March 2016. To analyze the heavy metals, inductively coupled plasma atomic emission spectroscopy (ICP-AES) was applied. SEM-EDX analysis indicated that metals of Al, Si, Mg, Na, Au, S, Ca, K, and Co were dominant in the structure of particles. The concentration of PM2.5 was found to be the highest in the final processing site (c), followed by primary processing site (a) and the aerated site (b). The mean concentrations of Al and Fe in all sampling sites of a, b, and c were 7.46 +/- 2.73, 1.48 +/- 0.59, 24.30 +/- 8.23 MUg/m3 and 4.97 +/- 2.83, 1.33 +/- 0.48, 16.48 +/- 7.36, respectively. The enrichment factor order of the trace elements was as follows: Cd > As > Pb > Zn > Cu > V > Cr > Ni > Mn > Fe > Al, with the highest EF value exceeding 10,000 for Cd at the a site. For all sampling sites in composting facilities, the cancer risk was more than > 1 * 10-4 as posed by the total of five carcinogenic metals (Pb, Cr, As, Ni, and Cd), indicating that risk factors were not negligible. PMID- 29574648 TI - Aqueous multivariate phototransformation kinetics of dissociated tetracycline: implications for the photochemical fate in surface waters. AB - Antibiotics are ubiquitous pollutants in aquatic systems and can exist as different dissociated species depending on the water pH. New knowledge of their multivariate photochemical behavior (i.e., the photobehavior of different ionized forms) is needed to improve our understanding on the fate and possible remediation of these pharmaceuticals in surface and waste waters. In this study, the photochemical degradation of aqueous tetracycline (TC) and its dissociated forms (TCH20, TCH-, and TC2-) was investigated. Simulated sunlight experiments and matrix calculations indicated that the three dissociated species had dissimilar photolytic kinetics and photooxidation reactivities. TC2- photodegraded the fastest due to apparent photolysis with a kinetic constant of 0.938 +/- 0.021 min-1, followed by TCH- (0.020 +/- 0.005 min-1) and TCH20 (0.012 +/- 0.001 min-1), whereas TCH- was found to be the most highly reactive toward *OH (105.78 +/- 3.40 M-1 s-1), and TC2- reacted the fastest with 1O2 (344.96 +/- 45.07 M-1 s-1). Water with relatively high pH (e.g., ~ 8-9) favors the dissociated forms of TCH- and TC2- which are most susceptible to photochemical loss processes compared to neutral TC. The calculated corresponding environmental half-lives (t1/2,E) in sunlit surface waters ranged from 0.05 h for pH = 9 in midsummer to 3.68 h for pH = 6 in midwinter at 45 degrees N latitude. The process was dominated by apparent photolysis (especially in summer, 62-91%), followed by 1O2 and *OH oxidation. Adjusting the pH to slightly alkaline conditions prior to UV or solar UV light treatment may be an effective way of enhancing the photochemical removal of TC from contaminated water. Graphical abstract Aqueous multiple photochemical behavior of dissociated tetracycline (TCH20, TCH-, and TC2-) is first comprehensively reported on revealing the phototransformation kinetics and implications for the fate in surface waters. PMID- 29574649 TI - Enhanced effect of EDDS and hydroxylamine on Fe(II)-catalyzed SPC system for trichloroethylene degradation. AB - This study presents a performance comparison of Fe(II)-catalyzed sodium percarbonate (SPC), Fe(II)-EDDS-catalyzed SPC, and of the innovative hydroxylamine hydrochloride (HA)-Fe(II)-EDDS-catalyzed SPC for the degradation of trichloroethylene (TCE) in water. TCE degradation was greater in the Fe(II)-EDDS catalyzed SPC system compared to the Fe(II)-catalyzed SPC system, indicating the effectiveness of adding EDDS as an enhancement factor for the removal of TCE. Moreover, TCE degradation was faster in the HA-Fe(II)-EDDS-catalyzed SPC system compared to the Fe(II)-EDDS-catalyzed SPC system, illustrating that HA can play a synergistic role in TCE degradation. Analysis of iron distribution in the three systems demonstrated that EDDS addition maintained iron in soluble form, and that the generation of soluble ferrous from ferric iron was expedited with addition of HA. Studies using nitrobenzene and carbon tetrachloride probes provided insights on the generation of hydroxyl radical (HO*) and superoxide anion radical (O2*-) in the three systems. A gradual increasing contribution of O2*- to TCE removal in Fe(II)-catalyzed SPC, Fe(II)-EDDS-catalyzed SPC, and HA-Fe(II)-EDDS-catalyzed SPC systems was verified through free-radical scavenger tests. Finally, monitoring of Cl- concentrations manifested the complete dechlorination of TCE. A possible mechanism of TCE degradation involving two pathways of HO* oxidation and O2*- reaction was proposed. PMID- 29574650 TI - Suitable flow pattern increases the removal efficiency of nitrogen in gravity sewers: a suitable anoxic and aerobic environment in biofilms. AB - The sewers have the function of carbon removal, which has been proven. But if the effect of nitrogen removal can be enhanced at the same time of carbon removal, it can lay a foundation for the realization of "sewer's working as a reactor." This paper investigated the effects of shear stress and C/N ratio on nitrogen removal through biofilms on the sewer inner wall and nitrogen transfer. The main conclusions are as follows: (1) nitrogen could be partially removed in sewers after a series of reactions; (2) the anaerobic, anoxic, aerobic environment and some bacteria related to nitrogen metabolism, which exist in the biofilm, promote the nitrification and denitrification; (3) a total of 722 functional genes involved in nitrogen metabolism were detected in the biofilm (C/N ratio of 10, shear stress of 1.4 Pa), accounting for 0.67% of all genes, and the functional genes related to denitrification were dominant.

AB - Patients with immunosuppression from human immunodeficiency virus (HIV) have been traditionally considered poor candidates for extracorporeal membrane oxygenation (ECMO) because of high in-hospital mortality and poor long-term survival. Highly active antiretroviral therapy (HAART) has improved survival rates in compliant HIV patients and reversible severe respiratory failure may warrant ECMO in this group. Immune reconstitution inflammatory syndrome (IRIS) involves excessive inflammatory response to a pathogen with paradoxical clinical deterioration following HAART initiation and may present as severe respiratory failure. Patients with IRIS supported on ECMO have been infrequently reported in literature. We report two HIV-positive patients who developed acute respiratory distress syndrome from IRIS necessitating successful veno-venous ECMO as salvage therapy. PMID- 29574651 TI - D-dimer predicts postoperative recurrence and prognosis in patients with liver metastasis of colorectal cancer. AB - BACKGROUND: Colorectal cancer is common, and its incidence is increasing throughout the world. The liver is a major metastatic site, and colorectal liver metastasis (CRLM) has a poor prognosis. Although liver resection is the most effective therapy for CRLM, postoperative recurrence is common. Thus, prognostic markers for CRLM are greatly needed. D-dimer, a fibrin cleavage product, has been shown to be related to colorectal tumor progression, and is also associated with malignant progression and recurrence in various cancers. Therefore, we evaluated the value of D-dimer in predicting the prognosis in CRLM. METHODS: We retrospectively evaluated 90 cases of resected CRLM to determine the correlation between D-dimer and patient survival. The cut-off value for D-dimer levels was determined using receiver operating characteristic curve analysis. RESULTS: Significant differences occurred in the recurrence group with higher D-dimer levels (P = 0.00736*), while the optimal cut-off value was 0.6 ug/mL. High D dimer levels (>= 0.6 ug/mL) were associated with poor recurrence-free survival (RFS; P = 0.0000841*) and cancer-specific survival (CSS; P = 0.00615*). In the multivariate analysis, D-dimer correlated with CRLM prognosis and independently predicted RFS (P = 0.0179*). CONCLUSION: High D-dimer levels were associated with poor RFS and CSS. D-dimer was an independent prognostic factor of RFS. Therefore, D-dimer may help predict recurrence and prognosis in patients with CRLM. PMID- 29574653 TI - Effect of Soluble Epoxide Hydrolase in Hyperoxic Acute Lung Injury in Mice. AB - Hyperoxic acute lung injury is a serious complication of oxygen therapy that causes high mortality. Inhibition of soluble epoxide hydrolase (sEH) has been reported to have protective effect on lipopolysaccharide-induced acute lung injury (ALI). This study investigates whether sEH plays any role in the pathogenesis of hyperoxic ALI. Wild-type and sEH gene knockout (sEH-/-) mice were exposed to 100% O2 for 72 h to induce hyperoxic ALI. Hyperoxia caused infiltration of inflammatory cells, elevation of interleukin-1beta and interleukin-6 levels, and deterioration of alveolar capillary protein leak as well as wet/dry weight ratio in the lung. The hyperoxia-induced pulmonary inflammation and edema were markedly improved in sEH-/- mice. Survival rate was significantly improved in sEH-/- mice compared with that in wild-type mice. Moreover, the levels of epoxyeicosatrienoic acids and heme oxygenase-1 activity were notably elevated in sEH-/- mice compared with those in wild-type mice after exposure to 100% O2 for 72 h. The nucleotide-binding domains and leucine-rich repeat pyrin domains containing 3 (NLRP3) inflammasome activation and caspase-1 activity induced by hyperoxia were inhibited in sEH-/- mice compared with those in wild-type mice. Inhibition of sEH by an inhibitor, AUDA, dampened hyperoxia induced ALI. sEH plays a vital role in hyperoxic ALI and is a potential therapeutic target for ALI. PMID- 29574654 TI - SERMs Promote Anti-Inflammatory Signaling and Phenotype of CD14+ Cells. AB - Signaling via estrogen receptors (ER) is recognized as an essential part of the immune regulation, and ER-mediated signaling is involved in autoimmune reactions. Especially ERalpha activation in immune cells has been suggested to skew cytokine production toward Th2/M2-type mediators, which can have protective effect on inflammatory diseases and reduce Th1 and Th17 responses. These effects are caused by increased alternative activation of macrophages and changes in the activation of different T cell populations. In humans, hormonal status has been shown to have a major impact on several inflammatory diseases. Selective estrogen receptor modulators (SERMs) are ER ligands that regulate ER actions in a tissue-specific manner mostly lacking the adverse effects of steroid hormones. The impact of SERMs on the immune system is less studied, but it is suggested that certain SERMs may also produce immunoprotective effects. Here, we show that two novel SERMs and raloxifene affect immune cells by promoting M2 macrophage phenotype, alleviating NFkappaB activity, inhibiting T cell proliferation, and stimulating the production of anti-inflammatory compounds such as IL10 and IL1 receptor antagonist. Thus, these compounds have high potency as drug candidates against autoimmune diseases. PMID- 29574655 TI - Musculoskeletal infections caused by Aerococcus urinae: a case-based review. AB - Aerococcus are Gram-positive bacteria that have been historically misidentified using standard techniques. We report a case of a 63-year-old man with septic oligoarthritis caused by Aerococcus urinae (isolated in two ankle synovial fluid cultures and in two blood cultures). Due to the lack of evidence found in a search performed to identify similar cases, a systematic review was conducted with the objective to identify and analyze all documented cases of musculoskeletal infections caused by Aerococcus urinae. A total of 8 cases were selected: 6 spondylodiscitis, 1 periarticular hip abscess, and 1 prosthetic hip infection. Similarly, as in other Aerococcus urinae invasive infections, these were presented predominantly in older males with history of urinary tract disease, being identified mostly by sequencing of the 16S rRNA or by matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), with an increasing incidence in the last years and generally with good sensitivity to beta-lactams (aminoglycosides were associated in some cases due to its synergistic effect). Additionally, 4 cases of musculoskeletal infections caused by Aerococcus viridans and 4 cases of Aerococcus urinae with ammoniacal and pervasive malodorous urine were identified; the last was a symptom also present in our case. In this review, we identify a recent increase of musculoskeletal infections caused by Aerococcus urinae, which as well as in series of other invasive infections could be well correlated with an increasing use of more sensible diagnosis methods in clinical laboratories. Therefore, we suggest that these probably will be more frequently diagnosed in the future. PMID- 29574656 TI - Differences in Type I interferon response in human lung epithelial cells infected by highly pathogenic H5N1 and low pathogenic H11N1 avian influenza viruses. AB - Influenza A virus infection induces type I interferons (IFNs alpha/beta) which activate host antiviral responses through a cascade of IFN signaling events. Herein, we compared highly pathogenic H5N1 and low pathogenic H11N1 avian influenza viruses isolated from India, for their replication kinetics and ability to induce IFN-beta and interferon-stimulating genes (ISGs). The H5N1 virus showed a higher replication rate and induced less IFN-beta and ISGs compared to the H11N1 virus when grown in the human lung epithelial A549 cells, reflecting the generation of differential innate immune responses during infection by these viruses. The non-structural 1 (NS1) protein, a major IFN-antagonist, known to help the virus in evading host innate immune response was compared from both the strains using bioinformatics tools. Analyses revealed differences in the composition of the NS1 proteins from the two strains that may have an impact on the modulation of the innate immune response. Intriguingly, H5N1 virus attenuated IFN-beta response in a non-NS1 manner, suggesting the possible involvement of other viral proteins (PB2, PA, PB1/PB1-F2) of H5N1 in synergy with NS1. Preliminary analyses of the above proteins of the two strains by sequence comparison show differences in charged residues. The insight gained will be useful in designing experimental studies to elucidate a probable role of the polymerase protein(s) in association with NS1 in inhibiting the IFN signaling and understanding the molecular mechanism governing the difference. PMID- 29574657 TI - Shallow groundwater quality and associated non-cancer health risk in agricultural areas (Poyang Lake basin, China). AB - Owing to their accessibility, shallow groundwater is an essential source of drinking water in rural areas while usually being used without control by authorities. At the same time, this type of water resource is one of the most vulnerable to pollution, especially in regions with extensive agricultural activity. These factors increase the probability of adverse health effects in the population as a result of the consumption of shallow groundwater. In the present research, shallow groundwater quality in the agricultural areas of Poyang Lake basin was assessed according to world and national standards for drinking water quality. To evaluate non-cancer health risk from drinking groundwater, the hazard quotient from exposure to individual chemicals and hazard index from exposure to multiple chemicals were applied. It was found that, in shallow groundwater, the concentrations of 11 components (NO3-, NH4+, Fe, Mn, As, Al, rare NO2-, Se, Hg, Tl and Pb) exceed the limits referenced in the standards for drinking water. According to the health risk assessment, only five components (NO3-, Fe, As, rare NO2- and Mn) likely provoke non-cancer effects. The attempt to evaluate the spatial distribution of human health risk from exposure to multiple chemicals shows that the most vulnerable area is associated with territory characterised by low altitude where reducing or near-neutral conditions are formed (lower reaches of Xiushui and Ganjiang Rivers). The largest health risk is associated with the immune system and adverse dermal effects. PMID- 29574658 TI - Colloid mobilization and heavy metal transport in the sampling of soil solution from Duckum soil in South Korea. AB - Colloid mobilization is a significant process governing colloid-associated transport of heavy metals in subsurface environments. It has been studied for the last three decades to understand this process. However, colloid mobilization and heavy metal transport in soil solutions have rarely been studied using soils in South Korea. We investigated the colloid mobilization in a variety of flow rates during sampling soil solutions in sand columns. The colloid concentrations were increased at low flow rates and in saturated regimes. Colloid concentrations increased 1000-fold higher at pH 9.2 than at pH 7.3 in the absence of 10 mM NaCl solution. In addition, those were fourfold higher in the absence than in the presence of the NaCl solution at pH 9.2. It was suggested that the mobility of colloids should be enhanced in porous media under the basic conditions and the low ionic strength. In real field soils, the concentrations of As, Cr, and Pb in soil solutions increased with the increase in colloid concentrations at initial momentarily changed soil water pressure, whereas the concentrations of Cd, Cu, Fe, Ni, Al, and Co lagged behind the colloid release. Therefore, physicochemical changes and heavy metal characteristics have important implications for colloid facilitated transport during sampling soil solutions. PMID- 29574659 TI - The 5alpha-Reductase Inhibitor Finasteride Exerts Neuroprotection Against Ischemic Brain Injury in Aged Male Rats. AB - Progesterone (P4) exerts potent neuroprotection both in young and aged animal models of stroke. The neuroprotection is likely to be mediated by allopregnanolone (ALLO) metabolized from P4 by 5alpha-reductase, since the neuroprotection is attenuated by the 5alpha-reductase inhibitor finasteride, which was done only with young animals though. Thus, we do not know the contribution of ALLO to the P4-induced neuroprotection in aged animals. We examined effects of finasteride on the P4-induced neuroprotection in aged (16-18 month-old) male rats subjected to transient focal cerebral ischemia. Transient focal cerebral ischemia was induced by left middle cerebral artery occlusion (MCAO) and occlusion of the bilateral common carotid arteries. MCAO rats were given an 8 mg/kg P4 6 h after MCAO followed by the same treatment once a day for successive 3 days. Finasteride, a 5alpha-reductase inhibitor, at 20 mg/kg was intraperitoneally injected 30 min prior to the P4-injections. P4 markedly reduced neuronal damage 72 h after MCAO, and the P4-induced neuroprotection was apparently suppressed by finasteride in the aged animals. However, post-ischemic administration of finasteride alone (20 mg/kg) significantly prevented neuronal damage and the impairment of Rotarod performance after MCAO in aged male rats, but not in young ones. The androgen receptor antagonist flutamide markedly suppressed the neuroprotection of finasteride in the cerebral cortex, but not in the striatum, suggesting the androgen receptor-dependent mechanism of the finasteride-induced neuroprotection in the cerebral cortex. Our findings suggested, for the first time, the potential of finasteride as a therapeutic agent in post-ischemic treatment of strokes in aged population. PMID- 29574661 TI - A meta-analysis of consanguinity and breast cancer. AB - BACKGROUND: There have been various publications stating that consanguinity both increases and decreases the risk of breast cancer. AIMS: The objective of this study was to determine the impact of consanguinity upon breast cancer. We conducted a systematic review of the literature and meta-analysis. METHODS: Eligible studies were identified on Medline and EMBASE updated to the 19 of September 2017. Studies with sufficient comparative data were included in a meta analysis. Analyses were carried out using RevMan software. RESULTS: Three comparative studies with a total of 317 individuals with breast cancer and 1459 controls. Reviewing the literature demonstrated conflicting conclusions of the influence of consanguinity upon breast cancer. The meta-analysis showed that there were no statistically significant associations between consanguinity and breast cancer though there was a trend protection from a history of consanguinity. CONCLUSION: Though there is limited literature published on the effects of parental consanguinity, the available data does not demonstrate that it is a risk factor for breast cancer. PMID- 29574660 TI - Site, trigger, quenching mechanism and recovery of non-photochemical quenching in cyanobacteria: recent updates. AB - Cyanobacteria exhibit a novel form of non-photochemical quenching (NPQ) at the level of the phycobilisome. NPQ is a process that protects photosystem II (PSII) from possible highlight-induced photo-damage. Although significant advancement has been made in understanding the NPQ, there are still some missing details. This critical review focuses on how the orange carotenoid protein (OCP) and its partner fluorescence recovery protein (FRP) control the extent of quenching. What is and what is not known about the NPQ is discussed under four subtitles; where does exactly the site of quenching lie? (site), how is the quenching being triggered? (trigger), molecular mechanism of quenching (quenching) and recovery from quenching. Finally, a recent working model of NPQ, consistent with recent findings, is been described. PMID- 29574662 TI - Evaluation of regulatory T lymphocytes and IL2Ra and FOXP3 gene expression in peripheral mononuclear cells from patients with amyotrophic lateral sclerosis. AB - BACKGROUND: Loss of neuroprotective role of CD4+ helper T cells, regulatory T cells, and M2 microglia constitutively results in the rapid neural death in the "rapidly progressive phase" of amyotrophic lateral sclerosis (ALS). AIM: We aimed to investigate relative count of CD4+ and regulatory T lymphocytes and expression level of IL2Ra and FOXP3 genes in peripheral blood mononuclear cells (PBMCs) from patients with ALS. METHOD: We performed a flow cytometric analysis on PBMC from 38 patients with ALS and 32 controls to determine the count of CD4+ and CD4+CD25+ cells. Quantitative real-time PCR analyses were implemented to determine the level of expression of FOXP3 and IL-2Ralpha (CD25) genes in the peripheral blood mononucleated cells. RESULTS: We found a significant higher proportion of CD4+ T cells (p value < 0.001), along with a significantly reduced proportion of CD4+CD25+ Treg cells (p value = 0.001, p value = 0.02), in the peripheral blood of patient's with ALS. CONCLUSION: The results of our study are in line with the hypothesis that in the early phase of ALS, neuroprotective helper T cells infiltrate in the affected areas in the lumbar spinal cord. This was reflected in higher peripheral percentage of CD4+ helper T cells and higher expression of FOXP3 and IL-2Ralpha. The observed demise in the number of active CD4+CD25+ regulatory T cells might indicate early signs of progression to later stages of ALS in our study group. Interestingly, disease duration was the sole independent significant determining factor that predicted CD4+CD25+ regulatory T cell counts in the peripheral blood of patients at various stages of ALS, according to a logistic regression model.

AB - Multiple sclerosis (MS) is a chronic inflammatory disorder with several genetic and environmental factors being implicated in its pathogenesis. Protein prenylation as one of the important posttranslational modifications of proteins has crucial role in immune system regulation. In the current case-control study, we compared expression of five genes coding for the different subunits of proteins implicated in protein prenylation in 50 Iranian MS patients with those of healthy subjects. No significant difference has been found in FNTA and PGGT1B expressions between cases and controls. Spearman correlation analysis between FNTA relative expression and disease duration showed significant correlation in male patients (r = - 0.671, P = 0.024) but not female patients (r = 0.253, P = 0.12). FNTB expression was significantly higher in MS patients compared with healthy subjects. Spearman correlation analysis between FNTB relative expression and disease duration showed significant correlation in male patients (r = -0.876, P = 0.004) but not female patients (r = 0.296, P = 0.06). RABGGTA was significantly upregulated in total MS patients, total male patients, female patients aged between 30 and 40 and male patients aged >40 compared with corresponding control groups. RABGGTB was significantly downregulated in total MS patients, total female patients, and female patients aged > 40 compared with corresponding control groups. Totally, we demonstrated dysregulation of protein prenylation pathway in MS patients compared with healthy subjects. Future studies are needed to find the clinical implication of this pathway in MS patients.

AB - The formation of dorsal-ventral axis of the spinal cord is controlled largely by dorsal signals such as Wnts (which are members of the wingless + MMTV integrants, Int family), besides ventral signals such as sonic hedgehog (Shh). Wnt3a, one of the Wnt family members, is involved in multiple cellular functions, including self-renewal, proliferation, differentiation, and motility. Here, we aim to study the mechanism of the regulation of chicken spinal cord patterning by Wnt3a. In this study, Wnt3a was ectopically expressed in the spinal cord of developing chicken embryos by in ovo electroporation. The results of immunofluorescent staining revealed that Wnt3a ectopic expression caused the abnormality of commissural axonal projection and the formation of nerve fibers was interrupted. It is worth noting that neurons in the ventricular zone, especially motor neurons, could not migrate laterally after the Wnt3a overexpression, which led to the malformation of motor column. In addition, we found that neurons could not protrude axons outwardly after overexpression of Wnt3a in the spinal cord. It was also found that Wnt3a overexpression inhibited the outgrowth of processes in culturing SH-SY5Y cells. In conclusion, we proposed that Wnt3a regulates neuronal morphology, which subsequently disrupts axonal projection and motor neuron positioning during spinal cord development. PMID- 29574665 TI - Exercise Blood Pressure Guidelines: Time to Re-evaluate What is Normal and Exaggerated? AB - Blood pressure responses to graded exercise testing can provide important diagnostic and prognostic information. While published guidelines outline what constitutes a "normal" and "abnormal" (i.e., exaggerated) blood pressure response to exercise testing, the widespread use of exaggerated blood pressure responses as a clinical tool is limited due to sparse and inconsistent data. A review of the original sources from these guidelines reveals an overall lack of empirical evidence to support both the normal blood pressure responses and their upper limits. In this current opinion, we critically evaluate the current exercise blood pressure guidelines including (1) the normal blood pressure responses to graded exercise testing; (2) the upper limits of this normal response; (3) the blood pressure criteria for test termination; and (4) the thresholds for exaggerated blood pressure responses. We provide evidence that exercise blood pressure responses vary according to subject characteristics, and subsequently a re-evaluation of what constitutes normal and abnormal responses is necessary to strengthen the clinical utility of this assessment. PMID- 29574666 TI - Impact of increasing treatment rates on cost-effectiveness of subcutaneous immunotherapy (SCIT) in respiratory allergy: a decision analytic modelling approach. AB - BACKGROUND: Specific immunotherapy is the only causal treatment in respiratory allergy. Due to high treatment cost and possible severe side effects subcutaneous immunotherapy (SCIT) is not indicated in all patients. Nevertheless, reported treatment rates seem to be low. This study aims to analyze the effects of increasing treatment rates of SCIT in respiratory allergy in terms of costs and quality-adjusted life years (QALYs). METHODS: A state-transition Markov model simulates the course of disease of patients with allergic rhinitis, allergic asthma and both diseases over 10 years including a symptom-free state and death. Treatment comprises symptomatic pharmacotherapy alone or combined with SCIT. The model compares two strategies of increased and status quo treatment rates. Transition probabilities are based on routine data. Costs are calculated from the societal perspective applying German unit costs to literature-derived resource consumption. QALYs are determined by translating the mean change in non preference-based quality of life scores to a change in utility. Key parameters are subjected to deterministic sensitivity analyses. RESULTS: Increasing treatment rates is a cost-effective strategy with an incremental cost effectiveness ratio (ICER) of 3484?/QALY compared to the status quo. The most influential parameters are SCIT discontinuation rates, treatment effects on the transition probabilities and cost of SCIT. Across all parameter variations, the best case leads to dominance of increased treatment rates while the worst case ICER is 34,315?/QALY. Excluding indirect cost leads to a twofold increase in the ICER. CONCLUSIONS: Measures to increase SCIT initiation rates should be implemented and also address improving adherence. PMID- 29574668 TI - Cannabidiol Reverses Deficits in Hippocampal LTP in a Model of Alzheimer's Disease. AB - Here we demonstrate for the first time that cannabidiol (CBD) acts to protect synaptic plasticity in an in vitro model of Alzheimer's disease (AD). The non psycho active component of Cannabis sativa, CBD has previously been shown to protect against the neurotoxic effects of beta amyloid peptide (Abeta) in cell culture and cognitive behavioural models of neurodegeneration. Hippocampal long term potentiation (LTP) is an activity dependent increase in synaptic efficacy often used to study cellular mechanisms related to memory. Here we show that acute application of soluble oligomeric beta amyloid peptide (Abeta1-42) associated with AD, attenuates LTP in the CA1 region of hippocampal slices from C57Bl/6 mice. Application of CBD alone did not alter LTP, however pre-treatment of slices with CBD rescued the Abeta1-42 mediated deficit in LTP. We found that the neuroprotective effects of CBD were not reversed by WAY100635, ZM241385 or AM251, demonstrating a lack of involvement of 5HT1A, adenosine (A2A) or Cannabinoid type 1 (CB1) receptors respectively. However in the presence of the PPARgamma antagonist GW9662 the neuroprotective effect of CBD was prevented. Our data suggests that this major component of Cannabis sativa, which lacks psychoactivity may have therapeutic potential for the treatment of AD. PMID- 29574667 TI - Chronic Swimming Exercise Ameliorates Low-Soybean-Oil Diet-Induced Spatial Memory Impairment by Enhancing BDNF-Mediated Synaptic Potentiation in Developing Spontaneously Hypertensive Rats. AB - Exercise and low-fat diets are common lifestyle modifications used for the treatment of hypertension besides drug therapy. However, unrestrained low-fat diets may result in deficiencies of low-unsaturated fatty acids and carry contingent risks of delaying neurodevelopment. While aerobic exercise shows positive neuroprotective effects, it is still unclear whether exercise could alleviate the impairment of neurodevelopment that may be induced by certain low fat diets. In this research, developing spontaneously hypertensive rats (SHR) were treated with chronic swimming exercise and/or a low-soybean-oil diet for 6 weeks. We found that performance in the Morris water maze was reduced and long term potentiation in the hippocampus was suppressed by the diet, while a combination treatment of exercise and diet alleviated the impairment induced by the specific low-fat diet. Moreover, the combination treatment effectively increased the expression of brain-derived neurotrophic factor (BDNF) and N-methyl D-aspartic acid receptor (NMDAR), which were both down-regulated by the low soybean-oil diet in the hippocampus of developing SHR. These findings suggest that chronic swimming exercise can ameliorate the low-soybean-oil diet-induced learning and memory impairment in developing SHR through the up-regulation of BDNF and NMDAR expression. PMID- 29574669 TI - Microglia Polarization and Endoplasmic Reticulum Stress in Chronic Social Defeat Stress Induced Depression Mouse. AB - Inflammation recently has been considered to be participated in the pathogenesis of major depressive disorder (MDD). However, the detailed mechanism of inflammation in depression has not been completely understood yet. In the present study, depression mice model was established by chronic social defeat stress (CSDS) method and confirmed by behavior examinations including forced swimming test and sucrose preference test. The decrease of spine density and postsynaptic density protein 95 (PSD95) in hippocampus further verified the depression model. Then, the microglia polarization state and endoplasmic reticulum (ER) stress were investigated. At transcriptional level, M1 marker (inducible nitric oxide synthase (iNOS), CD16, CD86, CXCL10) in CSDS mice was higher than that in control group while there was no difference in M2 marker (Arginase and CD206) between two groups. And it was observed in the hippocampus of CSDS induced depression mice that increased activated microglia was merged with iNOS instead of arginase by immunofluorescence staining. Furthermore, the M1 marker Interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha were increased in depression mice while the M1 marker IL-6 and M2 marker IL-10 remained unchanged. The expression of ER stress signaling factors, including protein kinase RNA-like ER kinase (PERK), Phosphorylated alpha-subunit of eukaryotic translation initiation factor 2(p eIF2alpha), C/EBP homologous protein (CHOP), and X-box binding protein 1(XBP1) were significantly higher in CSDS-induced depression mice than in control mice. In all, our results suggest that M1 polarization and ER stress play a vital role in MDD pathogenesis. PMID- 29574671 TI - Impact of Prenatal and Postnatal Treatment of Sodium Fluoride and Aluminum Chloride on Some Hormonal and Sensorimotor Aspects in Rats. AB - In most communities, there is a constant exposure to environmental pollutants with probable negative impact on the development of the nervous system. Among these pollutants are the sodium fluoride (NaF) and aluminum chloride (AlCl3) which may represent a real threat to the proper functioning of the brain. This study comprises two fundamentally different strategies; in the first one, pregnant rats were administered a daily dose of NaF (0.15 g /L) or AlCl3 (500 mg/L) in the drinking water either separately or in combination with each other from day 6 of gestation until just after weaning. In the second approach, the male rats born to mothers exposed to the pollutants were divided into two groups. In the first, rats were continued to be treated with the same pollutants administered to them in the drinking water at the same dose level until the age of 70 days. The rats of the second group were supplied with drinking water without either one of the pollutants for a similar period of time. The rats exposed to NaF separately or in combination with AlCl3 during the prenatal life and subsequently through the postnatal stages exhibited disturbance in the locomotor activities. This was concomitant with alterations in plasma, PTH, ACTH, and estradiol levels. Additionally, the serum levels of LH and testosterone were altered in the two groups treated with sodium fluoride during the prenatal and up to the weaning periods or in the group which continued to have the NaF until day 70 after birth. PMID- 29574670 TI - Voltage Gated Potassium Channel Kv1.3 Is Upregulated on Activated Astrocytes in Experimental Autoimmune Encephalomyelitis. AB - Kv1.3 is a voltage gated potassium channel that has been implicated in pathophysiology of multiple sclerosis (MS). In the present study we investigated temporal and cellular expression pattern of this channel in the lumbar part of spinal cords of animals with experimental autoimmune encephalomyelitis (EAE), animal model of MS. EAE was actively induced in female Dark Agouti rats. Expression of Kv1.3 was analyzed at different time points of disease progression, at the onset, peak and end of EAE. We here show that Kv1.3 increased by several folds at the peak of EAE at both gene and protein level. Double immunofluorescence analyses demonstrated localization of Kv1.3 on activated microglia, macrophages, and reactive astrocytes around inflammatory lesions. In vitro experiments showed that pharmacological block of Kv1.3 in activated astrocytes suppresses the expression of proinflammatory mediators, suggesting a role of this channel in inflammation. Our results support the hypothesis that Kv1.3 may be a therapeutic target of interest for MS and add astrocytes to the list of cells whose activation would be suppressed by inhibiting Kv1.3 in inflammatory conditions. PMID- 29574672 TI - Speciation Analysis of Trace Mercury in Sea Cucumber Species of Apostichopus japonicus Using High-Performance Liquid Chromatography Conjunction With Inductively Coupled Plasma Mass Spectrometry. AB - In this paper, a simple and cost-effective method using high-performance liquid chromatography in conjunction with inductively coupled plasma mass spectrometry with a rapid ultrasound-assisted extraction was used for analysis speciation of trace mercury in sea cucumber species of Apostichopus japonicus. The effective separation of inorganic mercury, methylmercury, and ethylmercury was achieved within 10 min using Agilent ZORBAX SB-C18 analytical and guard columns with an isocratic mobile phase consisting of 8% methanol and 92% H2O containing 0.12% L cysteine (m/v) and 0.01 mol/L ammonium acetate. Mercury species were extracted from A. japonicus samples using a solution containing 2-mercaptoethanol, L cysteine, and hydrochloric acid and sonicating for 0.5 h. The limits of detection of inorganic mercury, methylmercury, and ethylmercury were 0.12, 0.08, and 0.20 MUg/L, and the minimum detectable concentrations (measured at 0.500 g sample volume in 10.00 mL) were 2.4, 1.6, and 4.0 MUg/kg, respectively. Analysis of a scallop certified reference material (GBW 10024) revealed accordance between the experimental and certified values. This study provides a reference for the evaluation of mercury speciation in sea cucumber and other seafood. PMID- 29574673 TI - The Association Between Renal Tubular Dysfunction and Zinc Level in a Chinese Population Environmentally Exposed to Cadmium. AB - Studies in vivo and in vitro have shown a protective effect of zinc against renal dysfunction caused by cadmium exposure. However, limited human data is available. In this study, we evaluated the association between renal tubular dysfunction and body zinc burden in a Chinese population exposed to cadmium. A total of 331 subjects (170 women and 161 men) living in control and cadmium-polluted area were included. Blood cadmium (BCd), urinary cadmium (UCd), serum zinc (SZn), zinc in hair (HZn), Zn/Cd ratio, and urinary beta2Microglobulin (UBMG) were measured. The median UCd, BCd, SZn, and HZn were 2.8 and 13.6 MUg/g cr, 1.3 and 12.2 MUg/L, 1.31 and 1.12 mg/L, and 0.14 and 0.12 mg/g in subjects living in control and polluted areas. The UBMG level of subjects living in the polluted area was significantly higher than that of the control (0.27 vs 0.11 mg/g cr, p < 0.01). SZn, HZn, and Zn/Cd ratios were negatively correlated with UBMG (p < 0.05 or 0.01). Subjects with high SZn concentrations (>= 1.62 mg/L) had reduced risks of elevated UBMG [(odds ratio (OR) = 0.26, 95% confidence interval (CI) 0.07-0.99)] after controlling for multiple covariates compared with those with lower zinc levels. A similar result was observed in subjects with high HZn (OR = 0.09, 95% CI 0.02-0.48). The ORs of the second, third, and fourth quartiles of Zn/Cd ratio were 0.40 (95% CI 0.19-0.84), 0.14 (95% CI 0.06-0.37), and 0.01 (95% CI 0.02 0.18) for renal dysfunction compared with those of the first quartile, respectively. For those subjects with high level of UCd, high level of SZn and HZn also had reduced risks of elevated UBMG. The results of the present study show that high zinc body burden is associated with a decrease risk of renal tubular dysfunction induced by cadmium. Zinc nutritional status should be considered in evaluating cadmium-induced renal damage.

PMID- 29574675 TI - Warfarin-related nephropathy with acute kidney injury in a patient with immunoglobulin A nephropathy. AB - A 55-year-old man with Marfan syndrome taking warfarin for anticoagulant therapy after aortic valve replacement developed acute kidney injury (serum creatinine level of 9.01 mg/dL) and gross macrohematuria. Renal biopsy showed red cell casts in the renal tubules, glomerular crescent formation in the glomeruli with immunoglobulin A deposition, and global sclerosis. Based on these findings, the patient was diagnosed with warfarin-related nephropathy with acute kidney injury characterized by immunoglobulin A nephropathy with crescents. The warfarin was withdrawn, and his hematuria and renal function improved without immunosuppressive agents. PMID- 29574676 TI - Ischemic Stroke Risk in Medicare Beneficiaries with Central Retinal Artery Occlusion: A Retrospective Cohort Study. AB - INTRODUCTION: To determine the incidence of ischemic cerebral stroke in the 6 month periods preceding and following acute central retinal artery occlusion (CRAO) among Medicare beneficiaries. METHODS: A retrospective cohort study with comparison group conducted for calendar year 2013. Patients with CRAO were identified through National Medicare limited inpatient and institutional outpatient datasets for emergency services using ICD-9-CM code for CRAO (362.31). Patients with hip fractures (ICD-9-CM 820-820.9) during the same time period served as controls. Interval incident rates of ischemic stroke were determined from time-coded diagnoses of CRAO and hip fracture (index date zero) to date of principal discharge diagnosis of ischemic stroke (ICD-9-CM 434) recorded in the Medicare inpatient dataset. Risk of stroke was examined by comparing incidence among the two cohorts preceding and following the sentinel events. RESULTS: There were 3338 patients with CRAOs during 2013. The incidence of ischemic stroke peaked the second week following CRAO relative to patients with hip fracture (relative incidence = 33.1 [95% confidence interval 9.8-84.6]). CONCLUSIONS: Medicare beneficiaries who present to emergency rooms with CRAO or are hospitalized directly for this condition were at highest risk of ischemic stroke in the first 2 weeks following the ocular diagnosis. Patients with acute CRAO should be promptly evaluated for stroke and stroke prevention. PMID- 29574678 TI - Obstetric synthetic oxytocin use and subsequent hyperactivity/inattention problems in Danish children. AB - INTRODUCTION: The objective was to examine the association between obstetric synthetic oxytocin use and hyperactivity/inattention problems in offspring. MATERIAL AND METHODS: We identified children born in 2000-2003, enrolled in the Danish National Birth Cohort, with data on the Strengths and Difficulties Questionnaire (SDQ) reported by parents at age seven (n = 33 896) and age 11 (n = 27 561) and the children themselves around age 11 (n = 27 251). Information on oxytocin administration was provided in the Medical Birth Register. We estimated mean differences and odds ratios for childhood hyperactivity/inattention problems according to oxytocin exposure. RESULTS: Synthetic oxytocin was administered in 26% of the deliveries. We did not find the use of synthetic oxytocin during birth to be associated with childhood hyperactivity/inattention problems, whether analyzed in linear or logistic regression models. CONCLUSIONS: Our findings do not support any effects of obstetric use of synthetic oxytocin on hyperactivity/inattention problems in children when measured with the SDQ subscale at 7 or 11 years of age. PMID- 29574677 TI - An Integrated Socio-Environmental Model of Health and Well-Being: a Conceptual Framework Exploring the Joint Contribution of Environmental and Social Exposures to Health and Disease Over the Life Span. AB - PURPOSE OF THE REVIEW: Environmental and social determinants of health often co occur, particularly among socially disadvantaged populations, yet because they are usually studied separately, their joint effects on health are likely underestimated. Building on converging bodies of literature, we delineate a conceptual framework to address these issues. RECENT FINDINGS: Previous models provided a foundation for study in this area, and generated research pointing to additional important issues. These include a stronger focus on biobehavioral pathways, both positive and adverse health outcomes, and intergenerational effects. To accommodate the expanded set of issues, we put forward the Integrated Socio-Environmental Model of Health and Well-Being (ISEM), which examines how social and environmental factors combine and potentially interact, via multi factorial pathways, to affect health and well-being over the life span. We then provide applied examples including the study of how food environments affect dietary behavior. The ISEM provides a comprehensive, theoretically informed framework to guide future research on the joint contribution of social and environmental factors to health and well-being across the life span. PMID- 29574679 TI - In silico characterization of functional single nucleotide polymorphisms of folate pathway genes. AB - Folate metabolism genes are pivotal to critical biological processes and are related to several conditions, including developmental, cognitive, and cardiovascular anomalies. A systematic catalog of genetic polymorphisms in protein coding regions, regulatory transcription factor binding sites, and miRNA binding sites associated with folate pathway genes may contribute to personalized medicine. We performed a comprehensive computational survey of single nucleotide polymorphisms (SNPs) of folate pathway genes to highlight functional polymorphisms in the coding region, transcription factor binding sites, and miRNAs binding sites. Folate pathway genes were searched through PubMed and Kyoto Encyclopedia of Genes and Genomes pathway databases. SNPs were identified and characterized using the University of California, Santa Cruz genome browser and SNPnexus tool. Functional characterization of nonsynonymous SNPs (nsSNPS) was performed using bioinformatics tools, and common deleterious nsSNPs were identified. We identified 48 genes of folate pathway containing 287 SNPs in the coding regions. Out of these SNPs, rs5742905, rs45511401, and rs1801133 were predicted to be deleterious through four different bioinformatics tools. Three dimensional structures of two proteins with and without deleterious nsSNPs were predicted by SWISSPDB viewer and SuperPose. Besides, a total of 237 SNPs was identified in transcription factor binding sites using the Genomatix software suite and six miRNA target site SNPs using miRNASNP. This systematic and extensive in silico analysis of functional SNPs of folate pathway may provide a foundation for future targeted mechanistic, structure-function, and genetic epidemiological studies. PMID- 29574680 TI - Quality of both parents' cognitive guidance and quantity of early childhood education: Influences on pre-mathematical development. AB - BACKGROUND: Only a handful of longitudinal studies have explored the effects of both parents in early parenthood on children's cognitive development, and no study has controlled for simultaneous early childhood education and care (ECEC) experiences. AIMS: To examine the similarity of each parent's cognitive guidance and contribution to children's pre-mathematical outcomes across parent gender while controlling for amount of ECEC. SAMPLE: A longitudinal study on 66 Finnish two-parent families and their children. METHODS: Both parents' autonomy support and scaffolding behaviour were observed during play interactions with the child at 2;0. Children's numerical and spatial skills were tested at 3;0 and 4;0. Parental reports on amount of ECEC in months were collected at 2;0, 3;0, and 4;0. RESULTS: The two parenting constructs were conceptually similar across parent gender as demonstrated by fairly strong measurement equivalence. While mothers on average showed more scaffolding and equal amounts of autonomy support compared to fathers during play interaction, they displayed less variability in the former and more variability in the latter behaviour. The contribution of mothers' and fathers' cognitive guidance was more similar for children's numerical than spatial development. Both parents' education positively predicted autonomy support but not amount of ECEC exposure, which was positively related to numerical development. As expected, parents' education did not predict ECEC exposure, and child gender was not related to child outcomes. CONCLUSIONS: The findings are discussed in relation to measurement invariance and gender-neutral parenting in the context of early childhood. PMID- 29574681 TI - Effect of goal-directed haemodynamic therapy in free flap reconstruction for head and neck cancer. AB - BACKGROUND: In free flap reconstruction for head and neck cancer, achieving a haemodynamic target using excessive fluid infusion is associated with decreased flap survival rates and extended hospital stays. We hypothesized that goal directed haemodynamic therapy would improve flap survival rates and shorten hospitalization periods. METHODS: Patients scheduled for free flap reconstruction were randomly assigned to a goal-directed haemodynamic therapy group (n = 31) or a conventional haemodynamic therapy control group (n = 31). The control group received extra bolus fluid and ephedrine or norepinephrine to maintain a mean arterial pressure >= 65 mmHg. The goal-directed haemodynamic therapy group received a colloid solution as the extra bolus fluid to maintain a stroke volume variation < 12%; dobutamine, ephedrine, or norepinephrine was administered to maintain a cardiac index >= 2.5 l/min/m2 and mean arterial pressure >= 65 mmHg. Enhanced recovery after surgery protocols were not used except for fluid therapy. An otolaryngologist blinded to group assignments assessed flap outcomes and classified them as 'survival,' 'at risk' or 'failure.' RESULTS: The hospitalization period was not significantly different between the groups. The goal-directed haemodynamic therapy group had significantly shorter intensive care unit stays and a higher flap survival rate. The crystalloid volume was significantly lower in goal-directed haemodynamic therapy group. Reoperation rates, post-operative complications, and laboratory data including inflammatory markers were similar between the groups. CONCLUSION: Compared to conventional haemodynamic therapy, goal-directed haemodynamic therapy does not reduce hospitalization periods; it may, however, reduce the length of intensive care unit stays and increase flap survival rates. Further studies including multi centre trials with larger sample sizes are warranted. PMID- 29574682 TI - Human hepatocytes and cytochrome P450-selective inhibitors predict variability in human drug exposure more accurately than human recombinant P450s. AB - BACKGROUND AND PURPOSE: Drugs metabolically eliminated by several enzymes are less vulnerable to variable compound exposure in patients due to drug-drug interactions (DDI) or if a polymorphic enzyme is involved in their elimination. Therefore, it is vital in drug discovery to accurately and efficiently estimate and optimize the metabolic elimination profile. EXPERIMENTAL APPROACH: CYP3A and/or CYP2D6 substrates with well described variability in vivo in humans due to CYP3A DDI and CYP2D6 polymorphism were selected for assessment of fraction metabolized by each enzyme (fmCYP ) in two in vitro systems: (i) human recombinant P450s (hrP450s) and (ii) human hepatocytes combined with selective P450 inhibitors. Increases in compound exposure in poor versus extensive CYP2D6 metabolizers and by the strong CYP3A inhibitor ketoconazole were mathematically modelled and predicted changes in exposure were compared with in vivo data. KEY RESULTS: Predicted changes in exposure were within twofold of reported in vivo values using fmCYP estimated in human hepatocytes and there was a strong linear correlation between predicted and observed changes in exposure (r2 = 0.83 for CYP3A, r2 = 0.82 for CYP2D6). Predictions using fmCYP in hrP450s were not as accurate (r2 = 0.55 for CYP3A, r2 = 0.20 for CYP2D6). CONCLUSIONS AND IMPLICATIONS: The results suggest that variability in human drug exposure due to DDI and enzyme polymorphism can be accurately predicted using fmCYP from human hepatocytes and CYP-selective inhibitors. This approach can be efficiently applied in drug discovery to aid optimization of candidate drugs with a favourable metabolic elimination profile and limited variability in patients. PMID- 29574683 TI - Topical application of corticosteroids to tracheal tubes to prevent postoperative sore throat in adults undergoing tracheal intubation: a systematic review and meta-analysis. AB - Postoperative sore throat negatively affects patient satisfaction and recovery. Numerous randomised trials have tested the efficacy of corticosteroids applied to tracheal tubes to prevent postoperative sore throat. We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, Wanfang Database, and the China Academic Journal Network Publishing Database from inception to 7 December 2017. We included randomised controlled trials that assessed the efficacy and safety of corticosteroids applied to tracheal tubes, compared either with non analgesic controls and analgesic agents, in adults undergoing elective surgery under general anaesthesia. We pooled the data using a random-effects model and assessed the risk of random error by applying trial sequential analysis. Our primary outcomes were postoperative sore throat 24 h after surgery/extubation, and adverse events. The evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. We included 20 randomised controlled trials involving 2200 patients. Compared with non-analgesic controls, corticosteroids applied to tracheal tubes were associated with a reduced incidence of postoperative sore throat, risk ratio (95%CI) 0.39 (0.32-0.49) (18 trials, 1506 patients). Two randomised trials reported no adverse events. Compared with lidocaine, corticosteroids applied to tracheal tubes were associated with reduced incidence of postoperative sore throat, risk ratio (95%CI) 0.42 (0.35-0.51) (nine trials, 706 patients). Trial sequential analyses suggested the presence of firm evidence that corticosteroids applied to tracheal tubes were superior both to non-analgesic controls and lidocaine, in preventing postoperative sore throat. Evidence for postoperative sore throat for both comparisons was assessed as high quality. Only two trials sought adverse events; none were recorded. PMID- 29574685 TI - A prospective study of the hypertriglyceridemic waist phenotype and risk of incident ischemic stroke in a Chinese rural population. AB - OBJECTIVES: The hypertriglyceridemic waist phenotype has been reported as a practical tool to screen people with an increased risk of coronary artery disease and type 2 diabetes. The aim of this study was to investigate the relationship between the phenotype and ischemic stroke in a rural population in south China. MATERIALS AND METHODS: A total of 4081 participants aged over 35 years old without a stroke history were surveyed in 2009 and followed up from May 2014 to January 2016. The hypertriglyceridemic waist phenotype was defined as a waist circumference >=90 cm and a triglyceride level >=2.0 mmol/L in males, and a waist circumference >=85 cm and a triglyceride level >=1.5 mmol/L in females. A Cox regression model was used to estimate the association of the phenotype and ischemic stroke. RESULTS: After a mean of 5.16 years of follow-up, 138 individuals developed ischemic stroke. The hypertriglyceridemic waist phenotype was significantly associated with an increased risk of ischemic stroke before and after adjustment for confounding factors; the hazard ratios and 95% confidence intervals were 1.94 (1.27-2.96) and 1.71 (1.05-2.78), respectively. Further stratified analysis confirmed the associations in females (2.37 [1.09-5.14]) and smokers (3.20 [1.30-7.92]). A significant association of the phenotype and ischemic stroke risk was observed in subjects with normal glucose levels (2.94 [1.58-5.47]) but not in subjects with impaired fasting glucose and diabetes. CONCLUSIONS: The hypertriglyceridemic waist phenotype is associated with an increased risk of ischemic stroke and might be a simple tool to screen individuals with a high risk for ischemic stroke. PMID- 29574684 TI - Associations Between Polypharmacy and Cognitive and Physical Capability: A British Birth Cohort Study. AB - OBJECTIVES: To investigate longitudinal associations between polypharmacy and cognitive and physical capability and to determine whether these associations differ with cumulative exposure to polypharmacy. DESIGN: Prospective birth cohort study. SETTING: England, Scotland, and Wales. PARTICIPANTS: An eligible sample of men and women from the Medical Research Council National Survey of Health and Development with medication data at age 69 (N=2,122, 79%). MEASUREMENTS: Cognitive capability was assessed using a word learning test, visual search speed task, and the Addenbrooke's Cognitive Examination, Third Edition (ACE-III). Physical capability was measured using chair rise speed, standing balance time, walking speed, and grip strength. RESULTS: Polypharmacy (5-8 prescribed medications) was present in 18.2% of participants at age 69 and excessive polypharmacy (>=9 prescribed medications) in 4.7%. Both were associated with poorer cognitive and physical capability in models adjusted for sex, education, and disease burden. Stronger associations were found for excessive polypharmacy (e.g., difference in mean ACE-III scores comparing polypharmacy=-2.0, 95% CI=-2.8 to -1.1 and excessive polypharmacy=-2.9, 95% CI=-4.4 to -1.4 with no polypharmacy). Participants with polypharmacy at age 60 to 64 and at age 69 showed stronger Negative associations with cognitive and physical capability were stronger still in participants with polypharmacy at both age 60 to 64 and at age 69 (e.g. difference in mean chair rise speed, comparing polypharmacy with no polypharmacy at both ages=-3.9, 95% CI=-5.2 to -2.6 and at age 60-64 only=-2.5, 95% CI=-4.1 to -0.9). CONCLUSION: Polypharmacy at age 60 to 64 and age 69 was associated with poorer physical and cognitive capability, even after adjusting for disease burden. Stronger negative associations were seen in participants with longstanding polypharmacy, suggesting a cumulative, dose-dependent relationship (where dose is the number of prescribed medications). Future research aiming to improve cognitive and physical capability should consider interventions to reduce the duration and level of polypharmacy at younger ages, in addition to optimizing disease control with appropriate medications. PMID- 29574686 TI - Brassicales phylogeny inferred from 72 plastid genes: A reanalysis of the phylogenetic localization of two paleopolyploid events and origin of novel chemical defenses. AB - PREMISE OF THE STUDY: Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships among 14 of 17 families. Here we report a complete family-level phylogeny estimated using the plastid genome. METHODS: We conducted phylogenetic analyses on a concatenated data set comprising 44,926 bp from 72 plastid genes for species distributed across all 17 families. Our analysis includes three additional families, Tovariaceae, Salvadoraceae, and Setchellanthaceae, that were omitted in the previous phylotranscriptomic study. KEY RESULTS: Our phylogenetic analyses obtained fully resolved and strongly supported estimates for all nodes across Brassicales. Importantly, these findings are congruent with the topology reported in the phylotranscriptomic study. This consistency suggests that future studies could utilize plastid genomes as markers for resolving relationships within some notoriously difficult clades across Brassicales. We used this new phylogenetic framework to verify the placement of the At-alpha event near the origin of Brassicaceae, with median date estimates of 31.8 to 42.8 million years ago and restrict the At-beta event to one of two nodes with median date estimates between 85 to 92.2 million years ago. These events ultimately gave rise to novel chemical defenses and are associated with subsequent shifts in net diversification rates. CONCLUSIONS: We anticipate that these findings will aid future comparative evolutionary studies across Brassicales, including selecting candidates for whole-genome sequencing projects.

PMID- 29574688 TI - Dosing of Ceftriaxone and Metronidazole for Children With Severe Acute Malnutrition. AB - Infants and young children with severe acute malnutrition (SAM) are treated with empiric broad-spectrum antimicrobials. Parenteral ceftriaxone is currently a second-line agent for invasive infection. Oral metronidazole principally targets small intestinal bacterial overgrowth. Children with SAM may have altered drug absorption, distribution, metabolism, and elimination. Population pharmacokinetics of ceftriaxone and metronidazole were studied, with the aim of recommending optimal dosing. Eighty-one patients with SAM (aged 2-45 months) provided 234 postdose pharmacokinetic samples for total ceftriaxone, metronidazole, and hydroxymetronidazole. Ceftriaxone protein binding was also measured in 190 of these samples. A three-compartment model adequately described free ceftriaxone, with a Michaelis-Menten model for concentration and albumin dependent protein binding. A one-compartment model was used for both metronidazole and hydroxymetronidazole, with only 1% of hydroxymetronidazole predicted to be formed during first-pass. Simulations showed 80 mg/kg once daily of ceftriaxone and 12.5 mg/kg twice daily of metronidazole were sufficient to reach therapeutic targets. PMID- 29574689 TI - Targeting glial cannabinoid CB2 receptors to delay the progression of the pathological phenotype in TDP-43 (A315T) transgenic mice, a model of amyotrophic lateral sclerosis. AB - BACKGROUND AND PURPOSE: Cannabinoid CB2 receptors are up-regulated in reactive microglia in the spinal cord of TDP-43 (A315T) transgenic mice, an experimental model of amyotrophic lateral sclerosis. To determine whether this up-regulation can be exploited pharmacologically, we investigated the effects of different treatments that affect CB2 receptor function. EXPERIMENTAL APPROACH: We treated TDP-43 (A315T) transgenic mice with the non-selective agonist WIN55,212-2, alone or combined with selective CB1 or CB2 antagonists, as well as with the selective CB2 agonist HU-308, and evaluated their effects on the pathological phenotype. KEY RESULTS: WIN55,212-2 had modest beneficial effects in the rotarod test, Nissl staining of motor neurons, and GFAP and Iba-1 immunostainings in the spinal cord, which were mediated in part by CB2 receptor activation. HU-308 significantly improved the rotarod performance of the transgenic mice, with complete preservation of Nissl-stained motor neurons in the ventral horn. Reactive astrogliosis labelled with GFAP was also attenuated by HU-308 in the dorsal and ventral horns, in which CB2 receptors colocalize with this astroglial marker. Furthermore, HU-308 reduced the elevated Iba-1 immunostaining in the ventral horn of TDP-43 transgenic mice, but did not affect this immunoreactivity in white matter, in which CB2 receptors also colocalize with this microglial marker. CONCLUSIONS AND IMPLICATIONS: Our study shows an important role for glial CB2 receptors in limiting the progression of the pathological phenotype in TDP-43 (A315T) transgenic mice. Such benefits appear to derive from the activation of CB2 receptors concentrated in astrocytes and reactive microglia located in spinal dorsal and ventral horns. PMID- 29574690 TI - Our Buddies, Ourselves: The Role of Sexual Homophily in Adolescent Friendship Networks. AB - The present study tests the assumption that peers wield sufficient influence to induce sexual homophily (i.e., similarities in sexual experiences). Because girls face greater stigma for their sexual experiences than do boys, sexual homophily may be greater in girls' friendship networks than in boys'. Stochastic actor based models were used to analyze network data (n = 2,566; ages 14-18) from two high schools in the National Longitudinal Study of Adolescent to Adult Health. Sexual homophily was present in friendship networks. Girls and boys were equally susceptible to their friends' influence, but the former exhibited a stronger preference for befriending same sexual debut status peers than the latter. The findings suggest that adolescents-particularly girls-"curate" their networks to minimize peer ostracism. PMID- 29574691 TI - Rapid plasticity attenuation soon after birth revealed by habituation in newborn chicks. AB - Habituation reflects a form of experience-dependent plasticity whereby the organism progressively learns to ignore the irrelevant information repeatedly encountered. Here, we measured the freezing response to a repeated loud noise in three groups of newborn chicks (Gallus gallus) of different ages (1-2 Day old, 2 3 Day old, and 3-4 Day old) to investigate the ontogeny of habituation in this avian species. Habituation was already present 1 Day after hatching, revealing that the neural mechanisms underlying this form of plasticity are immediately active. Unexpectedly, however, we also found that in the second Day of stimulation the amount of learning was significantly attenuated in chicks of 3-4 days of age as compared to the younger animals, thus showing that 24-48 hr of maturation were sufficient to reduce plasticity. While previous findings in other animal species have proved the existence of a precocious critical period of plasticity in early cortical areas by means of sensory deprivation, our results demonstrate that during the initial development of an intact avian brain also the degree of plasticity underlying a learning process like habituation is maximal soon after birth, and then is subject to a rapid attenuation. PMID- 29574692 TI - P2Y12 receptor modulation of ADP-evoked intracellular Ca2+ signalling in THP-1 human monocytic cells. AB - BACKGROUND AND PURPOSE: The Gi -coupled, ADP-activated P2Y12 receptor is well characterized as playing a key role in platelet activation via crosstalk with the P2Y1 receptor in ADP-evoked intracellular Ca2+ responses. However, there is limited knowledge on the role of P2Y12 receptors in ADP-evoked Ca2+ responses in other blood cells. Here, we investigated the role of P2Y12 receptor activation in the modulation of ADP-evoked Ca2+ responses in human THP-1 monocytic cells. EXPERIMENTAL APPROACH: A combination of intracellular Ca2+ measurements, RT-PCR, immunocytochemistry, leukocyte isolation and siRNA-mediated gene knockdown were used to identify the role of P2Y12 receptor activation. KEY RESULTS: ADP-evoked intracellular Ca2+ responses (EC50 2.7 MUM) in THP-1 cells were abolished by inhibition of PLC (U73122) or sarco/endoplasmic reticulum Ca2+ -ATPase (thapsigargin). Loss of ADP-evoked Ca2+ responses following treatment with MRS2578 (IC50 200 nM) revealed a major role for P2Y6 receptors in mediating ADP evoked Ca2+ responses. ADP-evoked responses were attenuated either with pertussis toxin treatment, or P2Y12 receptor inhibition with two chemically distinct antagonists (ticagrelor, IC50 5.3 MUM; PSB-0739, IC50 5.6 MUM). ADP-evoked responses were suppressed following siRNA-mediated P2Y12 gene knockdown. The inhibitory effects of P2Y12 antagonists were fully reversed following adenylate cyclase inhibition (SQ22536). P2Y12 receptor expression was confirmed in freshly isolated human CD14+ monocytes. CONCLUSIONS AND IMPLICATIONS: Taken together, these data suggest that P2Y12 receptor activation positively regulates P2Y6 receptor-mediated intracellular Ca2+ signalling through suppression of adenylate cyclase activity in human monocytic cells. PMID- 29574693 TI - Physiologically Based Pharmacokinetic Modeling to Identify Physiological and Molecular Characteristics Driving Variability in Drug Exposure. AB - Prospectively defining the physiological and molecular characteristics most likely driving between-subject variability (BSV) in drug exposure provides the opportunity to inform the assessment of biomarkers to account for this variability. A physiologically based pharmacokinetic (PBPK) model was constructed and verified for dabrafenib. This model was then used to evaluate the physiological and molecular characteristics driving BSV in dabrafenib exposure. The capacity to discriminate a steady-state dabrafenib trough concentration >48 ng/mL was also evaluated. The mean simulated/observed ratios for the parameters describing dabrafenib exposure in single-dose, multiple-dose, and drug-drug interaction studies were between 0.78 and 1.23. Multivariable analysis indicated that consideration of baseline weight, body mass index, and CYP2C8, CYP3A4, and P gp abundance strongly predicts steady-state dabrafenib trough concentration above 48 ng/mL (ROC AUC = 0.94; accuracy = 86%). This is the first study to use a verified PBPK model to identify baseline physiological and molecular characteristics driving BSV in drug exposure. PMID- 29574694 TI - Comparing Meta-analysis and Individual Person Data Analysis Using Raw Data on Children's Understanding of Equivalence. AB - A prevailing theory of mathematical problem solving predicts that children will be less accurate solving a + b = c + __ problems versus a + b = __ + c. However, this has never been tested directly. Because of low base rates, information combined from multiple studies can help improve estimation accuracy and precision. This study compared meta-analysis and individual person data (IPD) analysis using raw data from 14 studies (N = 1,414; ns = 30-232; Mage reported = 8;7). Substantive results challenge the prevailing theory. Methodological results demonstrate the advantages of using meta-analysis and IPD over single-study analysis. Moreover, IPD can be more powerful than meta-regression for detecting between-study moderation effects. PMID- 29574695 TI - Children and young people's understanding of inherited conditions and their attitudes towards genetic testing: A systematic review. AB - Children and young people are increasingly likely to receive information regarding inherited health risks relevant to their genetic relatives and themselves. We reviewed the literature to determine what children and young people (21 years and younger) understand about inherited conditions and their attitudes towards genetic testing. We screened 1815 abstracts to identify 20 studies representing the perspectives of 1811 children and young people between the ages of 6 and 21 years (1498 children or young people at general population level risk from 9 studies, 313 affected/at risk from 15 studies). Children and young people at general population-level risk demonstrated a basic understanding that disease predisposition can be inherited within families. Those affected by or at risk of genetic conditions inferred their genetic status from observable, relational characteristics within their family and the results of personal genetic testing if it had occurred, but some misunderstandings of important genetic concepts were evident. Children and young people expressed interest in and a willingness to undertake personal genetic testing, but also articulated concerns about the limitations and risks of testing. Paediatric patients require developmentally-sensitive genetic counselling and support in navigating the unique landscape of their condition.

AB - Scaffolds generated from naturally occurring and synthetic polymers have been investigated in several applications because of their biocompatibility and tunable chemo-mechanical properties. Existing methods for generation of 3D polymeric scaffolds typically cannot be parallelized, suffer from low throughputs, and do not allow for quick and easy removal of the fragile structures that are formed. Current molds used in hydrogel and scaffold fabrication using solvent casting and porogen leaching are often single-use and do not facilitate 3D scaffold formation in parallel. Here, we describe a simple device and related approaches for the parallel fabrication of macroporous scaffolds. This approach was employed for the generation of macroporous and non macroporous materials in parallel, in higher throughput and allowed for easy retrieval of these 3D scaffolds once formed. In addition, macroporous scaffolds with interconnected as well as non-interconnected pores were generated, and the versatility of this approach was employed for the generation of 3D scaffolds from diverse materials including an aminoglycoside-derived cationic hydrogel ("Amikagel"), poly(lactic-co-glycolic acid) or PLGA, and collagen. Macroporous scaffolds generated using the device were investigated for plasmid DNA binding and cell loading, indicating the use of this approach for developing materials for different applications in biotechnology. Our results demonstrate that the device-based approach is a simple technology for generating scaffolds in parallel, which can enhance the toolbox of current fabrication techniques. PMID- 29574698 TI - Biphasic effects of THC in memory and cognition. AB - A generally undesired effect of cannabis smoking is a reversible disruption of short-term memory induced by delta-9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis. However, this paradigm has been recently challenged by a group of scientists who have shown that THC is also able to improve neurological function in old animals when chronically administered at low concentrations. Moreover, recent studies demonstrated that THC paradoxically promotes hippocampal neurogenesis, prevents neurodegenerative processes occurring in animal models of Alzheimer's disease, protects from inflammation-induced cognitive damage and restores memory and cognitive function in old mice. With the aim to reconcile these seemingly contradictory facts, this work will show that such paradox can be explained within the framework of hormesis, defined as a biphasic dose-response. PMID- 29574699 TI - Editorial. PMID- 29574700 TI - Genome-wide profiling of normal gastric mucosa identifies Helicobacter pylori- and cancer-associated DNA methylome changes. AB - The large geographic variations in the incidence of gastric cancer (GC) are likely due to differential environmental exposures, in particular to Helicobacter pylori (H. pylori) infection. We aimed to investigate the impact of H. pylori on the epigenome in normal gastric mucosa and methylation changes associated with cancer risk independent of H. pylori. A discovery set of normal gastric mucosa from GC cases (n = 42) and controls (n = 42), nested in a large case-control study and stratified by H. pylori status, were subjected to genome-wide methylation profiling. Single-nucleotide polymorphism arrays from peripheral blood leukocytes were used to conduct methylation quantitative trait loci (mQTL) analysis. A validation set of gastric mucosa samples (n = 180) was used in the replication phase. We found 1,924 differentially methylated positions (DMPs) and 438 differentially methylated regions (DMRs) associated with H. pylori infection, most of which were hypermethylated. Significant methylation alterations identified in the initial set were successfully replicated. Furthermore, the H. pylori-associated DMP/Rs showed marked stability ('epigenetic memory') after H. pylori clearance. Interestingly, we found 152 DMRs associated with cancer risk independent of the H. pylori status in normal gastric mucosa. The methylation score derived from three biomarkers was a strong predictor of GC. Finally, the mQTL analysis indicated that the H. pylori- and cancer-specific methylation signatures were minimally affected by genetic variation. The comprehensively characterized methylome changes associated with H. pylori infection and GC risk in our study might serve as potential biomarkers for early cancer progression in tumour-free gastric mucosa. PMID- 29574701 TI - Final safety, tolerability, and seizure outcomes in patients with focal epilepsy treated with adjunctive perampanel for up to 4 years in an open-label extension of phase III randomized trials: Study 307. AB - OBJECTIVE: To evaluate long-term safety/tolerability and seizure outcomes in patients with focal seizures treated with adjunctive perampanel in the open-label extension (OLEx) Study 307 (ClinicalTrials.gov identifier: NCT00735397). METHODS: Patients could enter the OLEx after completing one of the double-blind, phase III studies. Safety/tolerability and seizure outcomes (median percent reduction in seizure frequency per 28 days, and 50% responder and seizure freedom rates) were analyzed during the OLEx in cohorts with the same minimum perampanel exposure for all focal seizures and secondarily generalized seizures (SGS). An additional sensitivity analysis accounted for early dropouts from the OLEx. RESULTS: Of 1480 patients randomized across the double-blind studies, 1218 enrolled in the OLEx. The majority of patients (65.4%-80.9%) received a last daily dose of perampanel 12 mg and completed long-term assessment on the same, or one fewer, concomitant antiepileptic drug compared with baseline. The long-term safety/tolerability profile was consistent with the double-blind studies. Treatment-emergent adverse events (TEAEs) leading to discontinuation in >1% of patients were dizziness, irritability, and fatigue; TEAEs of clinical interest were stable for 4 years. In all cohorts, seizure outcome improvements were sustained over time. Median percent seizure reductions per 28 days reached 62.0% and 70.6% for patients with >=3 (n = 436) or >=4 (n = 78) years of exposure, respectively; corresponding 50% responder rates were 59.6% and 67.9%. The largest median percent seizure reduction per 28 days occurred in SGS for patients with SGS at baseline: 88.0% and 100.0% for patients with >=3 (n = 190) or >=4 (n = 28) years of exposure, respectively; in these cohorts 40.0% and 53.6% of patients, respectively, attained freedom from SGS. Median percent seizure reductions per 28 days were similar when early dropouts were accounted for. SIGNIFICANCE: Long-term (<=4 years) adjunctive perampanel treatment did not raise new safety/tolerability signals and was associated with markedly improved seizure control, particularly in patients with SGS at baseline.

PMID- 29574704 TI - A non-canonical tumor suppressive role for the long non-coding RNA MALAT1 in colon and breast cancers. AB - Long noncoding RNAs (lncRNAs) constitute one of the largest classes of transcripts and have been widely implicated in various diseases such as cancer. Increasing evidence suggests that several lncRNAs are dysregulated and play critical roles in tumorigenesis. LncRNAs can be regulated by key oncogenes and tumor suppressors, adding complexity to the intricate crosstalk between protein coding genes and the noncoding transcriptome. In our study, we investigated the effect that dysregulation of the key tumor suppressor PTEN has on the noncoding transcriptome. We identified the lncRNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) as a target of PTEN and find that this regulation is conserved in both human and mouse as well as with both chronic and acute PTEN dysregulation. We show that this regulation is at least in part microRNA (miRNA) dependent, and characterize the miRNAs that may be mediating this crosstalk. In summary, we establish and characterize a non-canonical PTEN-microRNA-MALAT1 axis that regulates tumorigenesis and describe for the first time that the MALAT1 lncRNA possesses novel tumor suppressive properties in colon and breast cancers. PMID- 29574703 TI - Genomic alterations in plasma DNA from patients with metastasized prostate cancer receiving abiraterone or enzalutamide. AB - In patients with metastatic castrate-resistant prostate cancer (mCRPC), circulating tumor DNA (ctDNA) analysis offers novel opportunities for the development of non-invasive biomarkers informative of treatment response with novel agents targeting the androgen-receptor (AR) pathway, such as abiraterone or enzalutamide. However, the relationship between ctDNA abundance, detectable somatic genomic alterations and clinical progression of mCRPC remains unexplored. Our study aimed to investigate changes in plasma DNA during disease progression and their associations with clinical variables in mCRPC patients. We analyzed ctDNA in two cohorts including 94 plasma samples from 25 treatment courses (23 patients) and 334 plasma samples from 125 patients, respectively. We conducted whole-genome sequencing (plasma-Seq) for genome-wide profiling of somatic copy number alterations and targeted sequencing of 31 prostate cancer-associated genes. The combination of plasma-Seq with targeted AR analyses identified prostate cancer-related genomic alterations in 16 of 25 (64%) treatment courses in the first cohort, in which we demonstrated that AR amplification does not always correlate with poor abiraterone and enzalutamide therapy outcome. As we observed a wide variability of ctDNA levels, we evaluated ctDNA levels and their association with clinical parameters and included the second, larger cohort for these analyses. Employing altogether 428 longitudinal plasma samples from 148 patients, we identified the presence of bone metastases, increased lactate dehydrogenase and prostate-specific antigen (PSA) as having the strongest association with high ctDNA levels. In summary, ctDNA alterations are observable in the majority of patients with mCRPC and may eventually be useful to guide clinical decision-making in this setting. PMID- 29574705 TI - A comprehensive approach to identifying repurposed drugs to treat SCN8A epilepsy. AB - OBJECTIVE: Many previous studies of drug repurposing have relied on literature review followed by evaluation of a limited number of candidate compounds. Here, we demonstrate the feasibility of a more comprehensive approach using high throughput screening to identify inhibitors of a gain-of-function mutation in the SCN8A gene associated with severe pediatric epilepsy. METHODS: We developed cellular models expressing wild-type or an R1872Q mutation in the Nav 1.6 sodium channel encoded by SCN8A. Voltage clamp experiments in HEK-293 cells expressing the SCN8A R1872Q mutation demonstrated a leftward shift in sodium channel activation as well as delayed inactivation; both changes are consistent with a gain-of-function mutation. We next developed a fluorescence-based, sodium flux assay and used it to assess an extensive library of approved drugs, including a panel of antiepileptic drugs, for inhibitory activity in the mutated cell line. Lead candidates were evaluated in follow-on studies to generate concentration response curves for inhibiting sodium influx. Select compounds of clinical interest were evaluated by electrophysiology to further characterize drug effects on wild-type and mutant sodium channel functions. RESULTS: The screen identified 90 drugs that significantly inhibited sodium influx in the R1872Q cell line. Four drugs of potential clinical interest-amitriptyline, carvedilol, nilvadipine, and carbamazepine-were further investigated and demonstrated concentration-dependent inhibition of sodium channel currents. SIGNIFICANCE: A comprehensive drug repurposing screen identified potential new candidates for the treatment of epilepsy caused by the R1872Q mutation in the SCN8A gene.

AB - Adult-onset neuroblastoma is rare and little is known about its biology and clinical course. There is no established therapy for adult-onset neuroblastoma. Anti-GD2 immunotherapy is now standard therapy in children with high-risk neuroblastoma; however, its use has not been reported in adults. Forty-four adults (18-71 years old) diagnosed with neuroblastoma between 1979 and 2015 were treated at Memorial Sloan Kettering Cancer Center. Five, 1, 5 and 33 patients had INSS stage 1, 2, 3 and 4 diseases, respectively. Genetic abnormalities included somatic ATRX (58%) and ALK mutations (42%) but not MYCN-amplification. In the 11 patients with locoregional disease, 10-year progression-free (PFS) and overall survival (OS) was 35.4 +/- 16.1% and 61.4 +/- 15.3%, respectively. Among 33 adults with stage 4 neuroblastoma, 7 (21%) achieved complete response (CR) after induction chemotherapy and/or surgery. Seven patients with primary refractory neuroblastoma (all with osteomedullary but no soft tissue disease) received anti GD2 antibodies, mouse or humanized 3F8. Antibody-related adverse events were similar to those in children, response rate being 71.4%. In patients with stage 4 disease at diagnosis, 5-year PFS was 9.7+/- 5.3% and most patients who were alive with disease at 5 years died of neuroblastoma over the next 5 years, 10-year OS being only 19.0 +/- 8.2%. Patients who achieved CR after induction had superior PFS and OS (p = 0.006, p = 0.031, respectively). Adult-onset neuroblastoma appeared to have different biology from pediatric or adolescent NB, and poorer outcome. Complete disease control appeared to improve long-term survival. Anti GD2 immunotherapy was well tolerated and might be beneficial. PMID- 29574716 TI - Acceptability of a text message-based fertility awareness application for family planning in Lucknow, India. AB - OBJECTIVE: To assess user satisfaction and acceptability toward a cell phone based short message system (SMS) application for fertility awareness. METHODS: Between July 1 and September 30, 2013, the present observational study recruited women of reproductive age who were presenting for family planning services in Lucknow, India, who were not pregnant, agreed to use the application, and understood basic English. The application collected information on an individual's menstrual cycle and, using the calendar days approach, predicted fertility. Based on an algorithm, the application sent a daily SMS text indicating the participant's fertility status. Participants completed an acceptability survey at the end of the 60-day pilot period. RESULTS: There were 21 participants enrolled. All reported that the application was highly acceptable, and found it to be private, secure, and convenient. All participants were interested in receiving future SMS reminders for tracking fertility. Most participants (20 [95%]) reported being likely or very likely to recommend the family planning application to friends. CONCLUSION: The application, with the aims of helping participants to identify their most fertile days once a month during ovulation and make informed decisions regarding fertility and contraception, was highly acceptable and might be useful in low-resource settings worldwide. Larger studies are needed for software optimization and determination of long-term effectiveness. PMID- 29574717 TI - Dynamic SAP102 expression in the hippocampal subregions of rats and APP/PS1 mice of various ages. AB - The hippocampus is a structurally and functionally complex brain area that plays important and diverse roles in higher brain functions, such as learning and memory, and mounting evidence indicates that different hippocampal subregions play distinctive roles. The hippocampus is also one of the first regions in the brain to suffer damage in Alzheimer's disease (AD). Synaptic dysfunction in the hippocampus, rather than neuronal loss per se, is paralleled by behavioural and functional deficits in AD. The membrane-associated guanylate kinase (MAGUK) family of proteins, including SAP102, PSD-95, PSD-93 and SAP97, have long been recognized as essential components of the postsynaptic density (PSD) at excitatory synapses. Hippocampal spines are the predominant synaptic transmission sites of excitatory glutamatergic synapses. During postnatal brain development, individual MAGUK members show distinct expression patterns. Although SAP102 has been confirmed as the dominant scaffold protein in neonatal synapses, its expression profiles in adult and ageing rodent hippocampi are discrepant. Furthermore, in AD brains, significantly reduced SAP102 protein levels have been found, suggesting that SAP102 may be related to AD progression; however, the precise mechanism underlying this result remains unclear. Herein, we observed distinct SAP102 expression profiles in the hippocampal CA1, CA3 and DG subregions of rats and APPswe/PS1dE9 (APP/PS1) mice at various ages using immunofluorescence. In Wistar rats, SAP102 was not only highly expressed in the hippocampal subregions of neonatal rats but also maintained relatively high expression levels in adult hippocampi and displayed no obvious decreases in the CA1 and DG subregions of aged rats. Surprisingly, we observed abnormally high SAP102 expression levels in the CA1 stratum moleculare and CA3 stratum polymorphum subregions of 2-month-old APP/PS1 mice, but low SAP102 levels in the DG and CA3 subregions of 7-month-old APP/PS1 mice, reflecting the subregion specific reactivity and vulnerability of AD mouse models in different disease stages. Our findings provide fundamental data to support the functional differences of SAP102 in different hippocampal subregions during postnatal periods and may serve as the basis for additional functional studies on SAP102 in normal physiological conditions and different stages of AD. PMID- 29574718 TI - Compromised regulation of the collecting duct ENaC activity in mice lacking AT1a receptor. AB - ENaC-mediated sodium reabsorption in the collecting duct (CD) is a critical determinant of urinary sodium excretion. Existing evidence suggest direct stimulatory actions of Angiotensin II (Ang II) on ENaC in the CD, independently of the aldosterone-mineralocorticoid receptor (MR) signaling. Deletion of the major renal AT1 receptor isoform, AT1a R, decreases blood pressure and reduces ENaC abundance despite elevated aldosterone levels. The mechanism of this insufficient compensation is not known. Here, we used patch clamp electrophysiology in freshly isolated split-opened CDs to investigate how AT1a R dysfunction compromises functional ENaC activity and its regulation by dietary salt intake. Ang II had no effect on ENaC activity in CDs from AT1a R -/- mice suggesting no complementary contribution of AT2 receptors. We next found that AT1a R deficient mice had lower ENaC activity when fed with low (<0.01% Na+ ) and regular (0.32% Na+ ) but not with high (~2% Na+ ) salt diet, when compared to the respective values obtained in Wild type (WT) animals. Inhibition of AT1 R with losartan in wild-type animals reproduces the effects of genetic ablation of AT1a R on ENaC activity arguing against contribution of developmental factors. Interestingly, manipulation with aldosterone-MR signaling via deoxycosterone acetate (DOCA) and spironolactone had much reduced influence on ENaC activity upon AT1a R deletion. Consistently, AT1a R -/- mice have a markedly diminished MR abundance in cytosol. Overall, we conclude that AT1a R deficiency elicits a complex inhibitory effect on ENaC activity by attenuating ENaC Po and precluding adequate compensation via aldosterone cascade due to decreased MR availability. PMID- 29574719 TI - IL-35, a hallmark of immune-regulation in cancer progression, chronic infections and inflammatory diseases. AB - Cytokine members of the IL-12 family have attracted enormous attention in the last few years, with IL-35 being the one of the most attractive-suppressive cytokine. IL-35 is an important mediator of regulatory T cell function. Regulatory T cells play key roles in restoring immune homeostasis after facing challenges such as infection by specific pathogens. Moreover, a crucial role for regulatory T cell populations has been demonstrated in several physiological processes, including establishment of fetal-maternal tolerance, maintenance of self-tolerance and prevention of autoimmune diseases. However, a deleterious involvement of immune regulatory T cells has been documented in specific inhibition of immune responses against tumor cells, promotion of chronic infections and establishment of chronic inflammatory disorders. In this review, we attempt to shed light on the concept of immune-homoeostasis on the aforementioned issues, taking IL-35 as the hallmark of regulatory responses. The dilemma between immune-mediated cancer treatment and inflammation is discussed. Histopathological indications of chronic vs. acute infections are elaborated. Moreover, the evidence that IL-35 requires additional immune-regulatory cytokines, such as IL-10 and TGF-beta, to induce effective and maximal anti inflammatory effects suggest that immune-regulation requires multi-factorial analysis of many immune playmakers rather than a specific immune target.

AB - Osteoarthritis (OA) is the most common disease of joints, which are complex organs where cartilage, bone and synovium cooperate to allow a range of movements. During progression of the disease, the function of all three main components is jeopardized. Nevertheless, the involvement of each tissue in OA development is still not established and is the topic of the present review. The OA therapies available are symptomatic, largely targeting pain management rather than disease progression. The strong need to develop a treatment for cartilage degeneration, bone deformation and synovial inflammation has led to research on the involvement of the endocannabinoid system in the development of OA. The current review discusses the research on this topic to date and notes the advantages of exploiting endocannabinoid system modulation for cartilage, bone and synovium homeostasis, which could prevent the further progression of OA. PMID- 29574721 TI - Folate deficiency inhibits the PCP pathway and alters genomic methylation levels during embryonic development. AB - Folate deficiency results in abnormal embryonic development, but the underlying mechanisms remain to be comprehensively investigated. Mutation of Vangl genes belonging to the planar cell polarity (PCP) pathway is associated with abnormal embryonic development, but the effect of folate deficiency on the PCP pathway is unclear. In this study, we found that folate deficiency inhibited Vangl gene expression and Vangl protein binding to the ligand Dvl. As a methyl donor, folate can chemically alter the DNA methylation levels of genomic sequences. Here, reduced representation bisulfite sequencing (RRBS) was employed to detect the methylation profiles of mouse embryos. The results confirmed that folate deficiency affected the genomic methylation levels of mouse embryos, which resulted in down-regulation of key genes involved in embryonic development. Gene ontology (GO) analysis suggested that the genes located in the differentially methylated regions (DMRs) are primarily involved in biological regulation, cellular processes, development, metabolism, and signaling pathways. The data revealed that folate deficiency inhibits the PCP pathway and alters genomic methylation profiles, which may be the underlying mechanisms through which folate deficiency impairs embryonic development.

AB - Accumulating evidences has shown that tumor suppressor candidate 7 (TUSC7) as a putatively tumor suppressor gene in various tumors. The low-expression of TUSC7 is related to poor prognosis, and increased the proliferation rate of tumor cells. Over-expression of TUSC7 could suppress tumor cell proliferation, migration, invasion, and colony formation, suggesting that TUSC7 might be a diagnostic and prognostic biomarker, as well as therapeutic target. In this review, we summarized the molecular mechanism and clinical significance of TUSC7 in tumorigenesis, tumor progression, and prognosis. PMID- 29574724 TI - Extremely thin layer plastification for focused-ion beam scanning electron microscopy: an improved method to study cell surfaces and organelles of cultured cells. AB - Since the recent boost in the usage of electron microscopy in life-science research, there is a great need for new methods. Recently minimal resin embedding methods have been successfully introduced in the sample preparation for focused ion beam scanning electron microscopy (FIB-SEM). In these methods several possibilities are given to remove as much resin as possible from the surface of cultured cells or multicellular organisms. Here we introduce an alternative way in the minimal resin embedding method to remove excess of resin from two widely different cell types by the use of Mascotte filter paper. Our goal in correlative light and electron microscopic studies of immunogold-labelled breast cancer SKBR3 cells was to visualise gold-labelled HER2 plasma membrane proteins as well as the intracellular structures of flat and round cells. We found a significant difference (p < 0.001) in the number of gold particles of selected cells per 0.6 MUm2 cell surface: on average a flat cell contained 2.46 +/- 1.98 gold particles, and a round cell 5.66 +/- 2.92 gold particles. Moreover, there was a clear difference in the subcellular organisation of these two cells. The round SKBR3 cell contained many organelles, such as mitochondria, Golgi and endoplasmic reticulum, when compared with flat SKBR3 cells. Our next goal was to visualise crosswall associated organelles, septal pore caps, of Rhizoctonia solani fungal cells by the combined use of a heavy metal staining and our extremely thin layer plastification (ETLP) method. At low magnifications this resulted into easily finding septa which appeared as bright crosswalls in the back-scattered electron mode in the scanning electron microscope. Then, a septum was selected for FIB SEM. Cross-sectioned views clearly revealed the perforate septal pore cap of R. solani next to other structures, such as mitochondria, endoplasmic reticulum, lipid bodies, dolipore septum, and the pore channel. As the ETLP method was applied on two widely different cell types, the use of the ETLP method will be beneficial to correlative studies of other cell model systems and multicellular organisms. PMID- 29574725 TI - Personal risk factors associated with burnout among psychotherapists: A systematic review of the literature. AB - OBJECTIVES: Emotionally taxing job demands place psychotherapists at risk for burnout, often to the detriment of the therapist, clients, and the profession of psychotherapy (Maslach, 2007). The aim of the present systematic review was to (a) explore the levels of both burnout and job stress in psychotherapists, (b) identify tools used to measure work-related stress and burnout, and (c) identify personal risk factors for developing burnout among psychotherapists. METHOD: Databases PsycINFO, Medline, EMBASE, ASSIA, and CINHAL were searched. Forty articles met inclusion criteria. RESULTS: Over half of sampled psychotherapists reported moderate-high levels of burnout, with the majority of results based on quantitative cross-sectional self-report surveys. Younger age, having less work experience, and being overinvolved in client problems were the most common personal risk factors for moderate-high levels of stress and burnout among psychotherapists. CONCLUSION: It appears that psychotherapists commonly experience some burnout, and personal factors influence burnout development. PMID- 29574723 TI - Calcium-dependent potassium channels control proliferation of cardiac progenitor cells and bone marrow-derived mesenchymal stem cells. AB - KEY POINTS: Ex vivo proliferated c-Kit+ endogenous cardiac progenitor cells (eCPCs) obtained from mouse and human cardiac tissues have been reported to express a wide range of functional ion channels. In contrast to previous reports in cultured c-Kit+ eCPCs, we found that ion currents were minimal in freshly isolated cells. However, inclusion of free Ca2+ intracellularly revealed a prominent inwardly rectifying current identified as the intermediate conductance Ca2+ -activated K+ current (KCa3.1) Electrical function of both c-Kit+ eCPCs and bone marrow-derived mesenchymal stem cells is critically governed by KCa3.1 calcium-dependent potassium channels. Ca2+ -induced increases in KCa3.1 conductance are necessary to optimize membrane potential during Ca2+ entry. Membrane hyperpolarization due to KCa3.1 activation maintains the driving force for Ca2+ entry that activates stem cell proliferation. Cardiac disease downregulates KCa3.1 channels in resident cardiac progenitor cells. Alterations in KCa3.1 may have pathophysiological and therapeutic significance in regenerative medicine. ABSTRACT: Endogenous c-Kit+ cardiac progenitor cells (eCPCs) and bone marrow (BM)-derived mesenchymal stem cells (MSCs) are being developed for cardiac regenerative therapy, but a better understanding of their physiology is needed. Here, we addressed the unknown functional role of ion channels in freshly isolated eCPCs and expanded BM-MSCs using patch-clamp, microfluorometry and confocal microscopy. Isolated c-Kit+ eCPCs were purified from dog hearts by immunomagnetic selection. Ion currents were barely detectable in freshly isolated c-Kit+ eCPCs with buffering of intracellular calcium (Ca2+i ). Under conditions allowing free intracellular Ca2+ , freshly isolated c-Kit+ eCPCs and ex vivo proliferated BM-MSCs showed prominent voltage-independent conductances that were sensitive to intermediate-conductance K+ -channel (KCa3.1 current, IKCa3.1 ) blockers and corresponding gene (KCNN4)-expression knockdown. Depletion of Ca2+i induced membrane-potential (Vmem ) depolarization, while store operated Ca2+ entry (SOCE) hyperpolarized Vmem in both cell types. The hyperpolarizing SOCE effect was substantially reduced by IKCa3.1 or SOCE blockade (TRAM-34, 2-APB), and IKCa3.1 blockade (TRAM-34) or KCNN4-knockdown decreased the Ca2+ entry resulting from SOCE. IKCa3.1 suppression reduced c-Kit+ eCPC and BM MSC proliferation, while significantly altering the profile of cyclin expression. IKCa3.1 was reduced in c-Kit+ eCPCs isolated from dogs with congestive heart failure (CHF), along with corresponding KCNN4 mRNA. Under perforated-patch conditions to maintain physiological [Ca2+ ]i , c-Kit+ eCPCs from CHF dogs had less negative resting membrane potentials (-58 +/- 7 mV) versus c-Kit+ eCPCs from control dogs (-73 +/- 3 mV, P < 0.05), along with slower proliferation. Our study suggests that Ca2+ -induced increases in IKCa3.1 are necessary to optimize membrane potential during the Ca2+ entry that activates progenitor cell proliferation, and that alterations in KCa3.1 may have pathophysiological and therapeutic significance in regenerative medicine. PMID- 29574726 TI - Browning Index of Anthocyanin-Rich Fruit Juice Depends on pH and Anthocyanin Loss More Than the Gain of Soluble Polymeric Pigments. AB - : Browning index (BI, ABS520 nm /ABS420 nm ) is a measure of anthocyanin-rich fruit juice pigmentation quality. This study sought to determine the extent to which BI describes anthocyanin quality and degradation in fruit juices. Commercial fruit juices were assayed for monomeric anthocyanin (MA) content, percent polymeric color (%PC), pH, and BI. BI varied, 0.29 to 1.72, among cranberry, cherry, grape, aronia, and pomegranate juices. Principal component analysis (PCA) revealed that BI was strongly inversely associated with %PC, and positively correlated with MAs to a lesser extent. The BI of grape and cherry juices varied linearly with pH from 2.0 to 4.0 in pH-adjusted juices. Cherry and grape juices at pH approximately 2.0 to 4.0 were incubated at 50 degrees C to induce juice browning. BI and MA decreased, and %PC increased, but the amount of MA degradation was not explained by %PC. In the aged juices, BI and MA were strongly correlated using PCA. In aged grape juice, chromatographic analysis was used characterize anthocyanins, proanthocyanidins, and anthocyanin scission products. Anthocyanin loss and a gain of unresolved components absorbing at 420 nm decreased BI. Proanthocyanidins and co-eluting pigments with varying BI decreased during aging. Scission products did not account for anthocyanin loss. Thus, MA loss more so than the gain in pigments associated with juice proanthocyanidins contribute to the increase in %PC and decline of the BI during accelerated aging of grape juice. Thus, BI is a useful marker of fruit juice quality within juices of the same pH and anthocyanin composition. PRACTICAL APPLICATION: Fruit juice pigmentation depends on anthocyanins, pH, and other matrix components. Spectrophotometric methods to determine pigmentation include the browning index (ABS520 nm /ABS420 nm ), pH differential method for monomeric anthocyanin (MA) content, and bisulfite bleaching to determine percent polymeric color (%PC). In this study, anthocyanin-rich fruit juice browning index was strongly dependent on pH and MA content. MA loss, and to a lesser extent, a gain in newly-formed pigments at 420 nm contributed to the browning index change during aging. Therefore, browning index is strongly associated with MA content and is useful for assessing fruit juice quality. PMID- 29574727 TI - Distribution of cytochrome oxidase-rich patches in human primary visual cortex. AB - We studied the tangential distribution of cytochrome oxidase (CytOx)-rich patches (blobs) in the striate cortex (V1) of normally sighted Homo sapiens. We analyzed the spatial density and cross-sectional area of patches in CytOx-reacted tangential sections of flat-mounted preparations of V1 and surrounding areas. CytOx-rich patches were most clearly defined in the supragranular cortical layers of V1, particularly at middle levels of layer III. Variations in patch spatial density were subtle across different visual eccentricity representations. Within the binocular representation of V1, the average patch spatial density decreased slightly with increasing cortical eccentricity, from around 1.0 patch/mm2 in the foveal representation to 0.6 patch/mm2 at the representation of ~60 degrees eccentricity, but seemed to increase again at the representation of the monocular crescent. Across the entire sample, the cross-sectional area of patches (i.e., patch size) varied from approximately 0.2-0.8 mm2 , with a mean value of 0.32 mm2 . Notably, there was no significant variation in the mean patch size across eccentricity representations. Human patches are on average larger than those reported for nonhuman primate brains, and analysis of species with different brain sizes suggests an approximately linear relationship between V1 area and patch size. The relative constancy of patch metrics across eccentricities is in stark contrast with the exponential variation in V1 cortical magnification, suggesting a nearly invariant modular organization throughout human V1. PMID- 29574728 TI - Cross-validation of PAI scales for the detection of suspected ADHD in adults. AB - The purpose of this study was to cross-validate scales and subscales of the Personality Assessment Inventory (PAI) identified in previously published research against criterion variables for the identification of Attention Deficit/Hyperactivity Disorder (ADHD) in adults. Performance-based indicators of attention deficits from the Wechsler Adult Intelligence Scale-Fourth Edition were used as criterion variables. In a hierarchical logistic regression analysis, the addition of the PAI scales to the criterion variables did significantly improve the fit of the model, with an overall classification accuracy of 75%. Limitations of this study and implications for future research are discussed. PMID- 29574730 TI - Cigarette smoke modifies neutrophil chemotaxis, neutrophil extracellular trap formation and inflammatory response-related gene expression. AB - BACKGROUND AND OBJECTIVE: Cigarette smoking is a major risk factor for periodontitis, and smoking perturbs neutrophil reactive oxygen species production. This study tested the hypothesis that cigarette smoke extract (CSE) and its components/metabolites nicotine, cotinine and thiocyanate (SCN-), may influence neutrophil functions. MATERIAL AND METHODS: Chemotaxis was assessed in neutrophils pre-treated with CSE using real-time video microscopy. Neutrophil extracellular trap (NET) release in response to CSE, nicotine, cotinine, SCN- as well as to phorbol 12-myristate-13-acetate and hypochlorous acid following pre treatment with CSE, nicotine, cotinine or SCN- was assessed using fluorescence based assays. The impact of CSE and SCN- treatment on neutrophil respiratory burst- and inflammation-related gene expression (NFKBIE, DNAJB1, CXCL8, NCF1, NCF2, CYBB) was determined by real-time polymerase chain reaction. RESULTS: Both CSE and SCN- pre-treatment inhibited phorbol 12-myristate-13-acetate-stimulated NET release. Additionally, SCN- inhibited hypochlorous acid-stimulated NET formation, while SCN- alone stimulated NET release. Overall, neutrophils pre treated with CSE exhibited reduced speed, velocity and directionality relative to untreated neutrophils. Although CSE and SCN- promoted DNAJB1 expression, increased redox-related gene expression was only detected in response to SCN-. CONCLUSION: These results suggest that CSE can alter ex vivo neutrophil activation by mechanisms independent of SCN- and nicotine, and SCN- may contribute to the perturbed innate immune responses observed in smokers.

AB - Parenchymal sparing procedures are gaining interest in pancreatic surgery and recent studies have reported that minimally invasive pancreatic enucleation may be associated with enhanced outcomes when compared with traditional surgery. By meta-analyzing the available data from the literature, minimally invasive surgery is not at higher risk of pancreatic fistula and offers a number of advantages over conventional surgery for pancreatic enucleation. PMID- 29574731 TI - Commentary: A time to reap and a time to sow: reducing the adolescent suicide rate now and in the future: commentary on Cha et al. (2018). AB - Cha and colleagues have provided an erudite, lucid, and comprehensive survey of where research on adolescent suicide has been, and where it should go. Their paper provides a broad global picture of the descriptive epidemiology of adolescent suicide, describes environmental, psychological, social, and biological processes likely to be associated with suicidal risk, reviews extant approaches to the management of adolescent suicidal behavior, and makes recommendations for future research. This editorial will expand on some of their recommendations, and also remind readers, that, regardless of how much we still need to learn, we do possess knowledge that, if applied now, could help to reduce the adolescent suicide rate in the near term. PMID- 29574733 TI - Commentary: Understanding the impact of domestic violence on children, recognizing strengths, and promoting resilience: reflections on Harold and Sellers (2018). AB - Violence and abuse in families occurs frequently with significant impact on children of all ages. However, this type of interpersonal violence is often the least disclosed or discussed. Therefore, the Harold and Sellers paper is important to bring attention to the broad range of both behavioral and neuroscience research in this area and the clinical implications for children and adolescents including risk for later psychopathology. The commentary also expands an understanding of the impact and outcomes for very young children exposed to domestic violence. The authors provide a thorough description of the many prevention and intervention programs and approaches to help children exposed to domestic violence. In conclusion, it is essential to recognize that even at times of adversity for children and families, such as when domestic violence occurs, it is important to recognize strengths and support resilience. PMID- 29574732 TI - Commentary: Biological embedding of childhood adversity: where do we go from here? A reflection on Koss and Gunnar (2018). AB - The review by Koss & Gunna provides a scholarly overview of the role of the hypothalamic-pituitary-adrenal (HPA) axis in mediating the association between childhood adversity and psychopathology. Through their insightful observations, the authors craft a rich framework to critically appraise the current evidence and inform future research in this area. Overall, the review calls for a new generation of studies testing biological embedding hypotheses with greater attention to design, measurement, statistical models, and translational approaches. These new studies are much needed. By uncovering the causal pathways underlying the biological embedding of childhood adversity, we can gain important new tools to prevent the most impairing forms of psychopathology among the most vulnerable individuals in society. PMID- 29574734 TI - Commentary: The neonatal brain and the challenge of imaging biomarkers, reflections on Batalle et al. (2018). AB - This review by Batalle et al. comes at an important time in the field as neonatal imaging has matured to a point that important questions can now be asked in a more definitive way. Identifying imaging biosmarkers that reflect the prenatal and early childhood origins of cognitive ability, behavior, and risk for neuropsychiatric disorders is now possible, and this commentary offers suggestions for addressing some of the challenges that lie ahead. PMID- 29574735 TI - Commentary: Whither the epigenetics of child psychopathology? Some reflections provoked by Barker et al. (2018). AB - Barker et al.'s. () review addresses one of the most fundamental questions in the fields of child psychology and psychiatry - How can adverse experiences shape development to a sufficient degree and in profound and enduring ways to create long term risk for later mental disorder and disability? In particular they discuss the plausibility of differential methylation as an epigenetic mechanism by which such exposures can become neuro-biologically embedded. Our commentary rises six question relating to key issues that need to be addressed as we search for definitive evidence from human studies that such mechanisms actually do make an important causal contribution to abnormal trajectories of development to disorder. PMID- 29574736 TI - Commentary: Randomized controlled trials in autism spectrum disorder: state of the field and challenges for the future. AB - This issue of the Journal includes two articles summarizing the evidence from clinical trials aimed at improving symptoms of autism. French and Kennedy (Journal of Child Psychology and Psychiatry, 2018, xx, xxxx) systematically review randomized controlled trials (RCTs) aimed at an "early intervention" and focus on trials including children with or at risk of autism under age 6 years. Although no type of intervention were excluded from their review, none of the included 48 RCTs employed pharmacological modalities and the overwhelming majority tested psychological/behavioural interventions aimed at modifying aspects of observed behaviours that are abnormal in children with autism. Using the standard Cochrane tool for evaluating risk of bias, French and Kennedy conclude that many RCTs are of low quality, which throws into question the reliance that should be placed on the findings. PMID- 29574737 TI - Annual Research Review: Interparental conflict and youth psychopathology: an evidence review and practice focused update. AB - The quality of the interparental relationship is recognized as an important influence on child and adolescent psychopathology. Historically, clinically oriented research on this topic has focused on the impacts of parental divorce and domestic violence as primary interparental relationship influences on child outcomes, to the relative neglect of dimensional or qualitative features of the couple/interparental relationship for youth (child and adolescent) psychopathology. Recent research has highlighted that children are affected by attributes of interparental conflict, specifically how parents express and manage conflicts in their relationship, across a continuum of expressed severity and negativity - ranging from silence to violence. Furthermore, new evidence highlights that children's emotional, behavioral, social, academic outcomes, and future interpersonal relationships are adversely affected by conflict between parents/carers whether adults are living together or not (i.e. married or separated), or where children are or are not genetically related to their rearing parents (e.g. adoption). We review evidence and present an integrated theoretical model, highlighting how children are affected by interparental conflict and what this evidence base means for effective intervention and prevention program development, as well as the development of possible cost-benefit models. Additionally, we review policy implications of this research and highlight some very recent examples of UK-based policy focusing on addressing the interparental relationship and its impact on youth psychopathology.

AB - Arseneault's review is a timely reminder of the strong evidence for the negative impact of school bullying, especially although not only on the victims of it. It is particularly important in dealing with the evidence for causal links, mechanisms and possible moderating factors. In this Commentary, I raise some issues about the definition of bullying; the importance of separating out the bully/victim category; differing impacts of types of victimisation, and notably cyber victimization, perhaps interacting with gender; and evidence on school antibullying policies and impact of interventions. PMID- 29574739 TI - Reimagining the environment in developmental psychopathology: from molecules to effective interventions. AB - The Journal of Child Psychology and Psychiatry's Annual Research Review (ARR) is a must-read special issue of the journal that presents a series of major reviews of key topics in the field. This year the ARR consists of eight reviews, each accompanied by a commentary from a leading expert in the field, on a diverse range of topics addressing, in complementary ways, the key role of the environment in child psychopathology and in leveraging change in the service of prevention and intervention. Topics include epigenetics, stress physiology, neonatal imaging, interparental conflict, bullying, autism treatments and suicide. The papers considered together represent the very best of contemporary child psychology and psychiatry research. PMID- 29574740 TI - Annual Research Review: The state of autism intervention science: progress, target psychological and biological mechanisms and future prospects. AB - BACKGROUND: There has been recent systematic review of key evidence in psychosocial intervention in autism but little review of biological treatments. METHODS: We analyse the current literature from the perspective of intervention and mechanism targets across social and biological development. RESULTS: The overall quality of trials evidence in autism intervention remains relatively low, despite some recent progress. Many treatments in common use have little or no evidence base. This is very concerning in such an important disorder. A variety of psychosocial interventions can show effect to improve some short-term effects on children's immediate dyadic social interactions, for instance with caregivers. But showing true effectiveness in this developmental disorder requires generalisation of such effects into wider social contexts, on autism symptoms and in long-term progress in development. Only a few interventions so far have begun to show this. A number of early phase interventions on biological targets have shown real promise, but none has yet progressed to larger scale effectiveness trials on behavioural or symptom outcomes. CONCLUSIONS: There has been enough progress in psychosocial intervention research now to be able to begin to identify some evidence-based practice in autism treatment. To consolidate and improve outcomes, the next phase of intervention research needs improved trial design, and an iterative approach building on success. It may also include the testing of potential synergies between promising biological and psychosocial interventions. PMID- 29574741 TI - Rational modification of Corynebacterium glutamicum dihydrodipicolinate reductase to switch the nucleotide-cofactor specificity for increasing l-lysine production. AB - l-lysine is an important amino acid in animals and humans and NADPH is a vital cofactor for maximizing the efficiency of l-lysine fermentation. Dihydrodipicolinate reductase (DHDPR), an NAD(P)H-dependent enzyme, shows a variance in nucleotide-cofactor affinity in bacteria. In this study, we rationally engineered Corynebacterium glutamicum DHDPR (CgDHDPR) to switch its nucleotide-cofactor specificity resulting in an increase in final titer (from 82.6 to 117.3 g L-1 ), carbon yield (from 0.35 to 0.44 g [g glucose]-1 ) and productivity (from 2.07 to 2.93 g L-1 hr-1 ) of l-lysine in JL-6 DeltadapB::Ec dapBC115G,G116C in fed-batch fermentation. To do this, we comparatively analyzed the characteristics of CgDHDPR and Escherichia coli DHDPR (EcDHDPR), indicating that hetero-expression of NADH-dependent EcDHDPR increased l-lysine production. Subsequently, we rationally modified the conserved structure of cofactor-binding motif, and results indicated that introducing the mutation K11A or R13A in CgDHDPR and introducing the mutation R16A or R39A in EcDHDPR modifies the nucleotide-cofactor affinity of DHDPR. Lastly, the effects of these mutated DHDPRs on l-lysine production were investigated. The highest increase (26.2%) in l-lysine production was observed for JL-6 DeltadapB::Ec-dapBC115G,G116C , followed by JL-6 Cg-dapBC37G,G38C (21.4%) and JL-6 DeltadapB::Ec-dapBC46G,G47C (15.2%). This is the first report of a rational modification of DHDPR that enhances the l-lysine production and yield through the modulation of nucleotide cofactor specificity.

AB - The gastrointestinal (GI) tract is unique compared to all other internal organs; it is the only organ with its own nervous system and its own population of intrinsic sensory neurons, known as intrinsic primary afferent neurons (IPANs). How these IPANs form neuronal circuits with other functional classes of neurons in the enteric nervous system (ENS) is incompletely understood. We used a combination of light microscopy, immunohistochemistry and confocal microscopy to examine the topographical distribution of specific classes of neurons in the myenteric plexus of guinea-pig colon, including putative IPANs, with other classes of enteric neurons. These findings were based on immunoreactivity to the neuronal markers, calbindin, calretinin and nitric oxide synthase. We then correlated the varicose outputs formed by putative IPANs with subclasses of excitatory interneurons and motor neurons. We revealed that calbindin immunoreactive varicosities form specialized structures resembling 'baskets' within the majority of myenteric ganglia, which were arranged in clusters around calretinin-immunoreactive neurons. These calbindin baskets directly arose from projections of putative IPANs and represent morphological evidence of preferential input from sensory neurons directly to a select group of calretinin neurons. Our findings uncovered that these neurons are likely to be ascending excitatory interneurons and excitatory motor neurons. Our study reveals for the first time in the colon, a novel enteric neural circuit, whereby calbindin immunoreactive putative sensory neurons form specialized varicose structures that likely direct synaptic outputs to excitatory interneurons and motor neurons. This circuit likely forms the basis of polarized neuronal pathways underlying motility. PMID- 29574745 TI - A new method for selecting auricle positions in skull base reconstruction for temporal bone cancer. AB - OBJECTIVE: In advanced temporal bone carcinoma cases, we attempted to preserve as much of the auricle as possible from a cosmetic and functional perspective. Difficulties are associated with selecting an adequate position for reconstructed auricles intraoperatively. We improved the surgical procedure to achieve a good postoperative auricle position. METHODS: Nine patients were included in this study. All patients underwent subtotal removal of the temporal bone and resection of the external auditory canal while preserving most of the external ear, and lateral skull base reconstruction was performed with anterolateral thigh flaps. We invented a new device, the auricle localizer, to select the correct position for the replaced external ear. The head skin incision line and two points of three-point pin fixation were used as criteria, and a Kirschner wire was shaped as a basic line to match these criteria. Another Kirschner wire was shaped by wrapping it around the inferior edge of the external ear as the positioning line, and these two lines were then combined. To evaluate the postoperative auricle position, the auricle inclination angle was measured using head frontal cephalogram imaging. RESULTS: The external ear on the affected side clearly drooped postoperatively in nonlocalizer cases, whereas this was not obvious in localizer cases. Auricle inclination angles 1 year after surgery significantly differed between these two cases (P = 0.018). CONCLUSION: The surgical device, the auricle localizer, is useful for selecting intraoperative accurate auricle positions. The assessment index, the auricle inclination angle, is useful for quantitatively evaluating postoperative results. LEVEL OF EVIDENCE: 4 Laryngoscope, 2605-2610, 2018. PMID- 29574744 TI - Peptidoglycan induces bradykinin receptor 1 expression through Toll-like receptor 2 and NF-kappaB signaling pathway in human nasal mucosa-derived fibroblasts of chronic rhinosinusitis patients. AB - Numerous studies have demonstrated that Gram-positive microbiomes play an important role in the pathogenesis and in the way of treatment of chronic rhinosinusitis (CRS). Kinins are inflammatory mediators and one of their receptors, namely bradykinin receptor 1 (BKR1 or B1R), is believed to be induced and involved in inflammation in pathophysiological conditions. In the present study, we investigated the effect of peptidoglycan (PGN), a major cell wall component of G(+) bacteria, on BKR expression and its signaling pathway in nasal fibroblasts from CRS without nasal polyp (CRSsNP). The PGN induced increases in B1R mRNA and protein production. The induction was abolished by the NF-kappaB and protein kinase A inhibitor. In parallel, the PGN treatment directly activated IkappaB/NF-kappaB signaling and CREB phosphorylation. Interestingly, a further analysis suggested no involvement of cAMP/PKA/CREB pathway in this induction. The B1R expression and IkappaB/NF-kappaB signaling pathway could be attenuated by Toll-like receptor-2 (TLR2) blocking/neutralizing Ab. In a functional assay, the addition of B1R selective agonist (Des-Arg10 -kallidin) to the fibroblasts after PGN stimulation led to an increase in CXCL8 release and p38 MAPK and ERK1/2 phosphorylation, which could be inhibited by the B1R antagonist. Taken together, our results revealed for the first time that PGN can increase B1R expression in human nasal mucosa-derived fibroblasts through TLR2 activation and NF-kappaB signaling pathway. This induction functionally leads to MAPKs activation and CXCL8 release upon B1R stimulation. Our results also suggest that a major component of G(+) bacteria can participate in B1R upregulation in nasal mucosa during CRSsNP progression. PMID- 29574746 TI - Concentrates of triterpenic acids obtained from crude olive pomace oils: characterization and evaluation of their potential antioxidant activity. AB - BACKGROUND: Pentacyclic triterpenic acids (TA) are phytochemicals of increasing nutritional interest owing to their bioactive properties, such as anti inflammatory, antitumoral, antihyperglycemic and hepatoprotective. Crude olive pomace oils constitute a non-exploited significant source of these compounds. In the present study, concentrates of TA were extracted and characterized from crude olive pomace oils that were obtained by centrifugation and subsequent solvent extraction, respectively. Specifically, the concentrates were obtained from the byproduct generated in the filtration of the oils. The solids were subjected to Soxhlet extractions with hexane to remove the residual oil and then with ethanol for the TA extraction. RESULTS: Concentrates containing 850-980 g kg-1 TA were isolated from the oils obtained by centrifugation, whereas those isolated from oils obtained by hexane extraction presented levels of TA that ranged from 510 to 900 g kg-1 . Oleanolic (OA) and maslinic (MA) acids were the TA found in the concentrates. The relative contents of OA and MA were, respectively, 30:70 (w/w) and 77:23 (w/w). All concentrates also presented phenolic compounds at levels of g kg-1 and displayed slight antioxidant properties. CONCLUSION: Concentrates of TA, containing MA and OA, can be readily obtained from a byproduct generated by filtration of crude olive pomace oils. Concentrates isolated from oils obtained by centrifugation were rich in MA, whereas those from oils extracted with hexane were rich in OA. The concentrates showed slight antioxidant properties that can be mainly attributed to the presence of phenolic compounds and not to TA. (c) 2018 Society of Chemical Industry. PMID- 29574747 TI - Wiedemann-Steiner syndrome as a major cause of syndromic intellectual disability: A study of 33 French cases. AB - Wiedemann-Steiner syndrome (WSS) is a rare syndromic condition in which intellectual disability (ID) is associated with hypertrichosis cubiti, short stature, and characteristic facies. Following the identification of the causative gene (KMT2A) in 2012, only 31 cases of WSS have been described precisely in the literature. We report on 33 French individuals with a KMT2A mutation confirmed by targeted gene sequencing, high-throughput sequencing or exome sequencing. Patients' molecular and clinical features were recorded and compared with the literature data. On the molecular level, we found 29 novel mutations. We observed autosomal dominant transmission of WSS in 3 families and mosaicism in one family. Clinically, we observed a broad phenotypic spectrum with regard to ID (mild to severe), the facies (typical or not of WSS) and associated malformations (bone, cerebral, renal, cardiac and ophthalmological anomalies). Hypertrichosis cubiti that was supposed to be pathognomonic in the literature was found only in 61% of our cases. This is the largest series of WSS cases yet described to date. A majority of patients exhibited suggestive features, but others were less characteristic, only identified by molecular diagnosis. The prevalence of WSS was higher than expected in patients with ID, suggesting than KMT2A is a major gene in ID.

AB - Skeletal muscle fibers are giant multinucleated cells wherein individual nuclei govern the protein synthesis in a finite volume of cytoplasm; this is termed the myonuclear domain (MND). The factors that control MND size remain to be defined. In the present study, we studied the contribution of the NAD+ -dependent deacetylase, sirtuin 1 (SIRT1), to the regulation of nuclear number and MND size. For this, we isolated myofibers from mice with tissue-specific inactivation (mKO) or inducible overexpression (imOX) of SIRT1 and analyzed the 3D organisation of myonuclei. In imOX mice, the number of nuclei was increased whilst the average MND size was decreased as compared to littermate controls. Our findings were the opposite in mKO mice. Muscle stem cell (satellite cell) numbers were reduced in mKO muscles, a possible explanation for the lower density of myonuclei in these mice; however, no change was observed in imOX mice, suggesting that other factors might also be involved, such as the functional regulation of stem cells/muscle precursors. Interestingly, however, the changes in the MND volume did not impact the force-generating capacity of muscle fibers. Taken together, our results demonstrate that SIRT1 is a key regulator of MND sizes, although the underlying molecular mechanisms and the cause-effect relationship between MND and muscle function remain to be fully defined. PMID- 29574749 TI - Targeting EGFR-mediated autophagy as a potential strategy for cancer therapy. AB - Autophagy is a naturally occurring programed cellular catabolic process stimulated by cellular stress for energy homeostasis maintenance and elimination of harmful substances. It mostly works as pro-survival mechanism but on the other hand deregulation of autophagy has been linked to non-apoptotic cell death known as "type II programed cell death." Emerging evidences indicate that EGFR (epidermal growth factor receptor)-mediated RAS/RAF/MEK/ERK signaling pathway plays a critical role in the induction of autophagy in various tumors. It has further been established that this signaling pathway is also involved in several other anti-proliferative events such as apoptosis and senescence. However, the signaling pathway activity and effects are highly dependent on the cell type and the stimulus. It is currently being evident that autophagy induction by RAS/RAF/MEK/ERK pathway through small molecules may be a potential therapeutic strategy for cancer. However, to our best knowledge, the role of EGFR-mediated RAS/RAF/MEK/ERK signaling pathway in autophagy-mediated cell death and survival have not previously been reviewed. In this review, we discuss the current state of knowledge on how RAS/RAF/MEK/ERK signaling pathway regulates autophagy and the role of this EGFR-mediated autophagy in diseases. We further examine the cross talk between this EGFR-mediated autophagy and apoptosis as well as how this process is currently being utilized for cancer treatment and suggest promoting autophagy-related cell death by small molecules may be exploited to design better therapeutic strategies for early stage and locally advanced tumors. PMID- 29574750 TI - Impact of delayed umbilical cord clamping on public cord blood donations: can we help future patients and benefit infant donors? AB - BACKGROUND: Cord blood (CB) is a widely accepted stem cell source and its clinical utilization depends, to a great extent, on its cell content. Birth-to clamping (BTC) time of umbilical cord determines placental transfusion to the newborn, and the remaining blood that can be collected and banked. The 2017 Committee Opinion of the American College of Obstetrics and Gynecologists (ACOG) recommends a delay of "at least 30-60 seconds" before clamping the cord for all newborns to ensure adequate iron stores. The impact of delayed cord clamping (DCC) on public CB banking can be substantial. STUDY DESIGN AND METHODS: Cord blood units (CBUs) collected from 1210 mothers at one hospital were evaluated for total nucleated cells (TNCs) and weight/volume based on time to clamping. Bank staff recorded BTC time in seconds as reported by obstetricians; collections were performed ex utero. Immediate clamping was defined as BTC of less than 30 seconds, whereas DCC was defined as BTC of 30 seconds or more. RESULTS: Cord clamping was immediate in 903 (75%) and delayed in 307 (25%) deliveries. Successful recovery (% clinical CBUs) decreased 10-fold with DCC of more than 60 seconds (22% vs. 2.4%, p < 0.001). CBUs collected after DCC of more than 60 seconds had significantly lower TNC counts than those after DCC of less than 60 seconds (p < 0.0001). Furthermore, 38% to 46% of CBUs after DCC of more than 60 seconds had volume of less than 40 mL. CONCLUSION: Our study indicates that DCC of 30 to 60 seconds has a small negative impact on collection of high-TNC-count CBUs. However, increasing BTC to more than 60 seconds decreases significantly both TNC content and volume, reducing drastically the chances of obtaining clinically useful CBUs. PMID- 29574751 TI - Surgical site infection in immediate breast reconstruction: Does chemotherapy timing make a difference? AB - BACKGROUND AND OBJECTIVES: We aim to analyze the impact of chemotherapy timing on surgical site infections (SSI) after immediate breast reconstruction (IBR). METHODS: A retrospective review of patients undergoing IBR between 2010 and 2015 was performed. Patients were divided into four groups: those with neoadjuvant chemotherapy only, adjuvant chemotherapy only, both adjuvant and neoadjuvant, and those with no chemotherapy. Outcomes of interest included SSI and timing of post operative SSI. RESULTS: A total of 949 reconstructions were performed over the study period. Subgroup breakdown was as follows: A total of 56 (5.9%) neoadjuvant only, 173 (18.2%) adjuvant only, 18 (1.9%) both, and 702 (74.0%) none. Overall infection rates were 10.7%, 10.4%, 22.2%, and 6.1% in the four groups, respectively (P = 0.015). On multivariate analysis, no significant differences were observed when comparing presence or absence of chemotherapy in the overall reconstruction cohort or when subgrouped by reconstruction modality-autologous or alloplastic. There were no significant differences in time from neoadjuvant chemotherapy to surgery date noted between patients who developed a post operative SSI and those who did not (4.40 +/- 1.58 vs 4.72 +/- 1.39 weeks; P = 0.517). CONCLUSION: Chemotherapy timing did not increase the odds of surgical site infections in patients undergoing immediate breast reconstruction. PMID- 29574752 TI - Whole body ARHGAP21 reduction improves glucose homeostasis in high-fat diet obese mice. AB - GTPase activating proteins (GAPs) are ubiquitously expressed, and their role in cellular adhesion and membrane traffic processes have been well described. TBC1D1, which is a Rab-GAP, is necessary for adequate glucose uptake by muscle cells, whereas increased TCGAP, which is a Rho-GAP, decreases GLUT4 translocation, and consequently glucose uptake in adipocytes. Here, we assessed the possible involvement of ARHGAP21, a Rho-GAP protein, in glucose homeostasis. For this purpose, wild type mice and ARHGAP21 transgenic whole-body gene deficiency mice (heterozygous mice, expressing approximately 50% of ARHGAP21) were fed either chow (Ctl and Het) or high-fat diet (Ctl-HFD and Het-HFD). Het HFD mice showed a reduction in white fat storage, reflected in a lower body weight gain. These mice also displayed an improvement in insulin sensitivity and glucose tolerance, which likely contributed to reduced insulin secretion and pancreatic beta cell area. The reduction of body weight was also observed in Het mice and this phenomenon was associated with an increase in brown adipose tissue and reduced muscle weight, without alteration in glucose-insulin homeostasis. In conclusion, the whole body ARHGAP21 reduction improved glucose homeostasis and protected against diet-induced obesity specifically in Het-HFD mice. However, the mechanism by which ARHGAP21 leads to these outcomes requires further investigation. PMID- 29574753 TI - Peeking at a plant through the holes in the wall - exploring the roles of plasmodesmata. AB - Plasmodesmata (PD) are membrane-lined pores that connect neighbouring plant cells and allow molecular exchange via the symplast. Past studies have revealed the basic structure of PD, some of the transport mechanisms for molecules through PD, and a variety of physiological processes in which they function. Recently, with the help of newly developed technologies, several exciting new features of PD have been revealed. New PD structures were observed during early formation of PD and between phloem sieve elements and phloem pole pericycle cells in roots. Both observations challenge our current understanding of PD structure and function. Research into novel physiological responses, which are regulated by PD, indicates that we have not yet fully explored the potential contribution of PD to overall plant function. In this Viewpoint article, we summarize some of the recent advances in understanding the structure and function of PD and propose the challenges ahead for the community. PMID- 29574754 TI - MicroRNA-dependent regulation of KLF4 by glucose in vascular smooth muscle. AB - Diabetes is a major risk factor for cardiovascular disease and this is in part due to the effects of hyperglycemia on vascular smooth muscle cells. Small non coding microRNAs are known to control smooth muscle phenotype and arterial contractility and are dysregulated in diabetes. The effect of microRNAs on smooth muscle differentiation is in part mediated by the transcription factor KLF4 but the role of this mechanism in diabetic vascular disease is not fully understood. Herein, we have investigated the importance of hyperglycemia and diabetes for the expression of KLF4 in vascular smooth muscle and the involvement of miRNAs in this regulation. Hyperglycemia down-regulated KLF4 in vascular smooth muscle cells and similar results were found in arteries of diabetic mice and patients. This correlated with a Foxa2-dependent up-regulation of miR-29c, which targeted KLF4 in vascular smooth muscle cells. Importantly, by preventing downregulation of KLF4, the induction of smooth muscle contractile protein markers by glucose was inhibited. In conclusion, miR-29 mediated inhibition of KLF4 in hyperglycemic conditions contributes to increased expression of contractile markers in vascular smooth muscle cells. Further studies are warranted to determine the therapeutic implications of miR-29 inhibition in diabetic vascular disease. PMID- 29574755 TI - Community health needs assessment: a nurses' global health project in Vietnam. AB - BACKGROUND: Global health has been directed to providing solutions to various health issues cross-nations, and nurses have received wide recognition as a key health workforce to reduce health disparities globally. Nurses involved in global health research are required to implement evidence-based global nursing practices based on the assessments of local health needs. AIM: To assess health needs and to suggest future interventions in rural communities of Vietnam. METHODS: A multifaceted rapid participatory appraisal with information pyramid was used applying mixed methods from six sources: existing record review, surveys of community residents, surveys of healthcare providers, focus group discussions with community leaders, informal discussions with governmental health administrators and observations of community health station (CHS) facilities. RESULTS: The majority used the CHSs as primary health facilities with high satisfaction for services currently provided. However, there were needs for the stations to provide more comprehensive services including chronic diseases, and for healthcare providers to improve their competences. Community leaders showed high interest in health information for chronic diseases and strong commitment to involvement in the activities for health of their communities. The findings suggest future interventions in the areas of the enhancement of CHS' functions, human resources and the self-care capacity of community residents. CONCLUSION AND POLICY IMPLICATIONS: The rapid participatory appraisal approach emphasizing community participation and partnership was a useful tool to compile accurate information about the current needs of the community on health, the preparedness of healthcare services to meet community's demands and about community capacity. This process is fundamental to nurses, who initiate global health projects in resource-limited international countries, to generate evidences regarding practice, research and policy for taking responsibilities in promoting the sustainable development goals. PMID- 29574756 TI - Oxycodone-induced tolerance to respiratory depression: reversal by ethanol, pregabalin and protein kinase C inhibition. AB - BACKGROUND AND PURPOSE: Oxycodone, a prescription opioid, is a major drug of abuse, especially in the USA, and contributes significantly to opioid overdose deaths each year. Overdose deaths result primarily from respiratory depression. We have studied respiratory depression by oxycodone and have characterized how tolerance develops on prolonged exposure to the drug. We have investigated the role of PKC in maintaining tolerance and have examined whether ethanol or pregabalin reverses oxycodone-induced tolerance. EXPERIMENTAL APPROACH: Respiration was measured in male CD-1 mice by whole-body plethysmography. Mice were preinjected with oxycodone then implanted with mini-pumps (s.c.) delivering 20, 45 or 120 mg.kg-1 .day-1 oxycodone for 6 days and subsequently challenged with oxycodone (3 mg.kg-1 , i.p.) or morphine (10 mg.kg-1 , i.p.) to assess the level of tolerance. KEY RESULTS: Oxycodone-treated mice developed tolerance to oxycodone and cross tolerance to morphine-induced respiratory depression. Tolerance was less with 20 mg.kg-1 .day-1 than with 45 or 120 mg.kg-1 .day-1 oxycodone treatment. At doses that do not depress respiration, ethanol (0.3 g.kg 1 ), pregabalin (20 mg.kg-1 ) and calphostin C (45 MUg.kg-1 ) all reversed oxycodone-induced tolerance resulting in significant respiratory depression. Reversal of tolerance was less in mice treated with oxycodone (120 mg.kg-1 .day-1 ). In mice receiving ethanol and calphostin C or ethanol and pregabalin, there was no greater reversal of tolerance than seen with either drug alone. CONCLUSION AND IMPLICATIONS: These data suggest that oxycodone-induced tolerance is mediated by PKC and that reversal of tolerance by ethanol or pregabalin may be a contributory factor in oxycodone overdose deaths. PMID- 29574757 TI - Residue investigation of some phenylureas and tebuthiuron herbicides in vegetables by ultra-performance liquid chromatography coupled with integrated selective accelerated solvent extraction-clean up in situ. AB - BACKGROUND: Some trace amounts of urea herbicide residues can be transferred to humans via the food chain, thereby being potentially harmful to human health. The development of a robust analytical methodology for effective sample preparation and simultaneous determination of herbicide residues in vegetable samples is required for achieving food safety. RESULTS: The diuron-molecularly imprinted polymers (MIPs) synthesized have excellent affinity and high selectivity to phenylureas (monolinuron, isoproturon, diuron and linuron) and tebuthiuron. A novel automated procedure with better selectivity for vegetable sample treatment was developed by integrated matrix solid-phase dispersion-accelerated solvent extraction clean-up in situ. Five herbicides can be baseline separated with runtime down to 5 min by ultra-performance liquid chromatography, and good linearity was obtained with a correlation coefficient (r) of 0.9999. The limit of quantification of the method was in the range of 0.8-2.3 ug kg-1 . Diuron residue in cherry tomato sample was found to be 40 ug kg-1 . CONCLUSION: The developed method has satisfactory selectivity, good linearity, high sensitivity and accuracy as well as speediness, and can ensure rapid selective extraction and sensitive multi-residue analysis at low microgram per kilogram levels of the herbicides in vegetable food.

AB - BACKGROUND: Childhood asthma comprises different phenotypes with complex pathophysiology. Different asthma phenotypes evoke various clinical symptoms and vary in their responses to treatments. METHODS: We applied k-means clustering algorithm of twelve objective laboratory tests among 351 asthmatic children enrolled in the Taiwanese Consortium of Childhood Asthma Study (TCCAS). We constructed gene expression profiles of peripheral blood mononuclear cells (PBMC) from children with different asthma phenotypes. RESULTS: Five distinct phenotypes of childhood asthma were identified and can be characterized by either eosinophil predominant or neutrophil-predominant inflammatory characteristics. In the gene expression profile analysis, significant differences were noted for neutrophil predominant asthma, compared with samples from all the other asthma phenotypes. The vast majority of the differentially expressed genes in neutrophil-predominant asthma was associated with corticosteroid response. From an independent inhaled corticosteroid (ICS) response cohort, we also found neutrophils could be activated in this severe asthma phenotype and neutrophil-predominant asthma may be associated with corticosteroid nonresponsiveness. CONCLUSION: Phenotype clustering of childhood asthma can be helpful to identify clinically relevant patients and reveal different inflammatory characteristics in asthmatic children. Neutrophil-predominant asthma is the most severe asthma phenotype with poor corticosteroid response. Gene expression profile of different asthma phenotypes not only improve our knowledge of childhood asthma, but also can guide asthma precision medicine. PMID- 29574759 TI - Humanizing the mouse immune system to study splanchnic organ inflammation. AB - It is well known that alterations in splanchnic organ perfusion and/or immune regulation may produce inflammatory tissue injury similar to that observed in several human disorders such as ischaemia and reperfusion injury, food allergies, diabetes, inflammatory bowel disease and graft-versus-host disease. Mouse models have been tremendously important in defining the roles of the circulation, leukocyte trafficking, inflammatory mediator generation, immune regulation and the intestinal microbiota in the pathogenesis of acute and chronic inflammation. However, few of the promising interventions or therapeutics reported in mouse models of inflammatory diseases have been translated to clinically effective treatments in patients. There is growing concern that because of the significant differences that exist between the murine and human immune systems, mouse models may not adequately recapitulate the immuno-pathogenesis of inflammatory diseases. This inconvenient reality has prompted a number of investigators to undertake a series of studies to humanize the murine immune system via adoptive transfer of human lymphoid or progenitor cells into a new generation of immuno-deficient recipients. In this review, we summarize the recent advances that have been made in the development of humanized mice and describe how these mouse models are being used to study the pathophysiology of splanchnic organ inflammation. In addition, we discuss the limitations of the different approaches and present potential solutions for the continued improvement of these important animal models.

AB - Experimental games have previously been used to study principles of human interaction. Many such games are characterized by iterated or repeated designs that model dynamic relationships, including reciprocal cooperation. To enable the study of infinite game repetitions and to avoid endgame effects of lower cooperation toward the final game round, investigators have introduced random termination rules. This study extends previous research that has focused narrowly on repeated Prisoner's Dilemma games by conducting a controlled experiment of two player, random termination Centipede games involving probabilistic reinforcement and characterized by the longest decision sequences reported in the empirical literature to date (24 decision nodes). Specifically, we assessed mean exit points and cooperation rates, and compared the effects of four different termination rules: no random game termination, random game termination with constant termination probability, random game termination with increasing termination probability, and random game termination with decreasing termination probability. We found that although mean exit points were lower for games with shorter expected game lengths, the subjects' cooperativeness was significantly reduced only in the most extreme condition with decreasing computer termination probability and an expected game length of two decision nodes. PMID- 29574763 TI - Subgingival glycine powder air-polishing as an additional approach to nonsurgical periodontal therapy in subjects with untreated chronic periodontitis. AB - BACKGROUND AND OBJECTIVE: Glycine powder air-polishing (GPAP) is an alternative approach to removing subgingival plaque biofilms for effective periodontal therapy. This study aimed to investigate the effect of subgingival GPAP as an additional approach to nonsurgical periodontal treatment in subjects with chronic periodontitis. MATERIAL AND METHODS: Twenty-seven nonsmoking subjects were recruited. Two quadrants in each subject were randomly assigned, according to a split-mouth design, to receive scaling and root planing (SRP) and GPAP (Test group) or SRP and air flushing with water (Control group) at sites with probing depth >=5 mm. Clinical parameters, gingival crevicular fluid volumes and the concentrations of interleukin-1beta and interleukin-1ra in gingival crevicular fluid were measured at baseline and 1, 3 and 6 months after the treatments. RESULTS: At baseline, no statistically significant difference in periodontal and gingival crevicular fluid parameters was found between the Test and Control groups. Overall, the periodontal conditions of all subjects showed significant improvement after the treatments. Notably, the Test group showed greater reduction in gingival crevicular fluid volume (0.37 +/- 0.26 MUL) than the Control group (0.23 +/- 0.30 MUL) at 3 months (P < .05). The gingival crevicular fluid levels of interleukin-1beta and interleukin-1ra showed a significant decrease in both groups at 6 months, and no significant difference was found between the groups. CONCLUSION: These preliminary results suggest that GPAP, as an additional approach to nonsurgical periodontal treatment, may be beneficial for the short-term improvement of subclinical inflammation when measured by gingival crevicular fluid volume. Further longitudinal studies with larger sample sizes are required to clarify the exact benefits of GPAP treatment for controlling inflammation and maintaining long-term periodontal health. PMID- 29574762 TI - Deficient arginase II expression without alteration in arginase I expression attenuated experimental autoimmune encephalomyelitis in mice. AB - In the past there have been a multitude of studies that ardently support the role of arginase II (Arg II) in vascular and endothelial disorders; however, the regulation and function of Arg II in autoimmune diseases has thus far remained unclear. Here we report that a global Arg II null mutation in mice suppressed experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. During EAE, both Arg I and Arg II were induced in spinal cords, but only Arg II was induced in spleens and splenic dendritic cells (DCs). DC activation by lipopolysaccharide (LPS), CD40L or TLR8 agonist significantly enhanced Arg II expression without affecting Arg I expression. Conversely, DC differentiating cytokines [IL-4 and granulocyte macrophage-colony-stimulating factor (GM-CSF)] yielded opposite effects. In addition, Arg I and Arg II were regulated differentially during Th1 and Th17 cell polarization. Arg II deficiency in mice delayed EAE onset, ameliorated clinical symptoms and reduced myelin loss, accompanied by a remarkable reduction in the EAE-induced spinal cord expression of Th17 cell markers (IL-17 and RORgammat). The abundance of Th17 cells and IL 23+ cells in relevant draining lymph nodes was significantly reduced in Arg II knockout mice. In activated DCs, Arg II deficiency significantly suppressed the expression of Th17-differentiating cytokines IL-23 and IL-6. Interestingly, Arg II deficiency did not lead to any compensatory increase in Arg I expression in vivo and in vitro. In conclusion, Arg II was identified as a factor promoting EAE likely via an Arg I-independent mechanism. Arg II may promote EAE by enhancing DC production of Th17-differentiating cytokines. Specific inhibition of Arg II could be a potential therapy for multiple sclerosis.

PMID- 29574766 TI - In vitro evaluation of di(2-ethylhexyl)terephthalate-plasticized polyvinyl chloride blood bags for red blood cell storage in AS-1 and PAGGSM additive solutions. AB - BACKGROUND: Di(2-ethylhexyl)phthalate (DEHP) makes polyvinyl chloride flexible for use in blood bags and stabilizes the red blood cell (RBC) membrane preventing excessive hemolysis. DEHP migrates into the blood product and rodent studies have suggested that DEHP exposure may be associated with adverse health effects albeit at high dosages. Although structurally and functionally similar to DEHP, di(2 ethylhexyl)terephthalate (DEHT; or Eastman 168 SG [Eastman Chemical Company]) is metabolically distinct with a comprehensive and benign toxicology profile. This study evaluated RBC stability in DEHT-plasticized bags with AS-1 and PAGGSM compared to conventional DEHP-plasticized bags with AS-1. STUDY DESIGN AND METHODS: Thirty-six whole blood units were collected into CPD solution, leukoreduced, centrifuged, and divided into RBCs and plasma. To limit donor related variability, three ABO-identical RBCs were mixed together and then divided equally and stored among the three different plasticizer and additive solution combinations. RBCs from 12 trios were analyzed for a standard panel of in vitro variables on Day 0 and after storage. RESULTS: No individual bag on Day 42 exceeded the US 1.0% hemolysis criteria. While hemolysis during storage was higher in the DEHT bags, the PAGGSM RBCs were close to the control RBCs (0.38% vs. 0.32%, respectively). ATP retention was higher than 70% and potassium levels were similar regardless of plasticizer. Additional RBC variables exhibited some significant differences but were not viewed as clinically important. CONCLUSION: DEHT/PAGGSM provides similar hemolysis protection to that of DEHP/AS-1. Although hemolysis values with DEHT and AS-1 are higher than that of DEHP, DEHT is a potential DEHP alternative. PMID- 29574765 TI - Direct solid-state evidence of H2 -induced partial U(VI) reduction concomitant with adsorption by extracellular polymeric substances (EPS). AB - Adsorption of hexavalent uranium (U(VI)) by extracellular polymeric substances (EPS) has been studied, but the possibility of simultaneous U(VI) reduction mediated by EPS has not had experimental confirmation, as the reduction products have not yet been directly proven. Here, we reported the first direct evidence of lower-valent products of U(VI) immobilization by loosely associated EPS (laEPS) isolated from a fermenter strain of Klebsiella sp. J1 when the laEPS was exposed to H2 . During the 120-min tests for similarly 86% adsorption under O2 , N2 , and H2 , 8% more U was immobilized through a non-adsorptive pathway by the EPS for H2 than for N2 and O2 . A set of solid-state characterization tools (FT-IR, XPS, EELS, and TEM-EDX) confirmed partial reduction of U(VI) to lower-valence U, with the main reduced form being uraninite (UIV O2 ) nanoparticles, and the results reinforced the role of the reduction in accelerating U immobilization and shaping the characteristics of immobilized U in terms of valency, size, and crystallization. The laEPS, mostly comprised of carbohydrate and protein, contained non-cytochrome enzymes and electron carriers that could be responsible for electron transfer to U(VI). Taken together, our results directly confirm that EPS was able to mediate partial U(VI) reduction in the presence of H2 through non cytochrome catalysis and that reduction enhanced overall U immobilization. Our study fills in some gaps of the microbe-mediated U cycle and will be useful to understand and control U removal in engineered reactors and in-situ bioremediation. PMID- 29574767 TI - Patient-specific estimation of spatially variant image noise for a pinhole cardiac SPECT camera. AB - PURPOSE: New single photon emission computed tomography (SPECT) cameras using fixed pinhole collimation are increasingly popular. Pinhole collimators are known to have variable sensitivity with distance and angle from the pinhole aperture. It follows that pinhole SPECT systems will also have spatially variant sensitivity and hence spatially variant image noise. The objective of this study was to develop and validate a rapid method for analytically estimating a map of the noise magnitude in a reconstructed image using data from a single clinical acquisition. METHODS: The projected voxel (PV) noise estimation method uses a modified forward projector with attenuation effects to estimate the number of photons detected from each voxel in the field-of-view. We approximate the noise for each voxel as the standard deviation of a Poisson distribution with a mean equal to the number of detected photons. An empirical formula is used to address scaling discrepancies caused by image reconstruction. Calibration coefficients are determined for the PV method by comparing it with noise measured from a nonparametrically bootstrapped set of images of a spherical uniformly filled Tc 99m water phantom. Validation studies compare PV noise estimates with bootstrapped measured noise for 31 patient images (5 min, 340 MBq, 99m Tc tetrofosmin rest study). RESULTS: Bland-Altman analysis shows R2 correlations >=70% between the PV-estimated and -measured image noise. For the 31 patient cardiac images, the PV noise estimate has an average bias of 0.1% compared to bootstrapped noise and have a coefficient of variation (CV) <= 17%. The bootstrap approach to noise measurement requires 5 h of computation for each image, whereas the PV noise estimate requires only 64 s. In cardiac images, image noise due to attenuation and camera sensitivity varies on average from 4% at the apex to 9% in the basal posterior region of the heart. The standard deviation between 15 healthy patient study images (including physiological variability in the population) ranges from 6% to 16.5% over the length of the heart. CONCLUSIONS: The PV method provides a rapid estimate for spatially variant patient-specific image noise magnitude in a pinhole-collimated dedicated cardiac SPECT camera with a bias of -0.3% and better than 83% precision. PMID- 29574768 TI - Histone methylation and acetylation in macrophages as a mechanism for regulation of inflammatory responses. AB - Macrophages respond to noxious stimuli and contribute to inflammatory responses by eliminating pathogens or damaged tissue and maintaining homeostasis. Response to activation signals and maintenance of homeostasis require tight regulation of genes involved in macrophage activation and inactivation processes, as well as genes involved in determining their polarization state. Recent evidence has revealed that such regulation occurs through histone modifications that render inflammatory or polarizing gene promoters accessible to transcriptional complexes. Thus, inflammatory and anti-inflammatory genes are regulated by histone acetylation and methylation, determining their activation state. Herein, we review the current knowledge on the role of histone modifying enzymes (acetyltransferases, deacetylases, methyltransferases, and demethylases) in determining the responsiveness and M1 or M2 polarization of macrophages. The contribution of these enzymes in the development of inflammatory diseases is also presented. PMID- 29574769 TI - Crystal structure of exo-rhamnogalacturonan lyase from Penicillium chrysogenum as a member of polysaccharide lyase family 26. AB - Exo-rhamnogalacturonan lyase from Penicillium chrysogenum 31B (PcRGLX) was recently classified as a member of polysaccharide lyase (PL) family 26 along with hypothetical proteins derived from various organisms. In this study, we determined the crystal structure of PcRGLX as the first structure of a member of this family. Based on the substrate-binding orientation and substrate specificity, PcRGLX is an exo-type PL that cleaves rhamnogalacturonan from the reducing end. Analysis of PcRGLX-complex structures with reaction products indicate that the active site possesses an L-shaped cleft that can accommodate galactosyl side chains, suggesting side-chain-bypassing activity in PcRGLX. Furthermore, we determined the residues critical for catalysis by analyzing the enzyme activities of inactive variants. PMID- 29574770 TI - The origin of aliphatic hydrocarbons in olive oil.

AB - OBJECTIVES: Monoclonal antibody-based of cancer therapy has been considered as one of the most successful therapeutic strategies for both haematologic malignancies and solid tumours in the last two decades. Epidermal growth factor receptor (EGFR) family signalling pathways play a key role in the regulation of cell proliferation, survival and differentiation. Hence, anti-EGFR family mAbs is one of the most promising approaches in cancer therapy. KEY FINDINGS: Here, recent advances in anti-EGFR mAb including approved or successfully tested in preclinical and clinical studies have been reviewed. Although we focus on monoclonal antibodies against the EGF receptor, but the mechanisms underlying the effects of EGFR-specific mAb in cancer therapy, to some extend the resistance to existing anti-EGFR therapies and some therapeutic strategies to overcome resistance such as combination of mAbs on different pathways are briefly discussed as well. SUMMARY: The EGFR family receptors, is considered as an attractive target for mAb development to inhibit their consecutive activities in tumour growth and resistance. However, due to resistance mechanisms, the combination therapies may become a good candidate for targeting EGFR family receptors.

AB - Prenatal ultrasonography (US) in a 39 year-old woman revealed massive fetal ascites. A fetal abdomino-amniotic shunting procedure was performed. Subsequently, plain radiographs demonstrated diffuse gaseous distention of the bowel and multiple punctate calcifications in the left upper abdomen. Postnatal US examination showed multiple echogenic foci in the liver and the left upper abdomen, bowel wall thickening in the right-sided abdomen, and undescended testes. There was no intra-abdominal free air or loculated fluid collections. Medical management was instituted secondary to the clinical suspicion of omental calcification, necrotizing enterocolitis, and undescended testes. Follow-up US examination showed resolution of portal vein gas and bowel wall thickening. The neonate recovered fully. PMID- 29574773 TI - Omega-3 fatty acids modulate the lipid profile, membrane architecture, and gene expression of leiomyoma cells. AB - Uterine leiomyomas (fibroids or myomas) are the most common benign tumors of premenopausal women and new medical treatments are needed. This study aimed to determine the effects of omega-3 fatty acids on the lipid profile, membrane architecture and gene expression patterns of extracellular matrix components (collagen1A1, fibronectin, versican, or activin A), mechanical signaling (integrin beta1, FAK, and AKAP13), sterol regulatory molecules (ABCG1, ABCA1, CAV1, and SREBF2), and mitochondrial enzyme (CYP11A1) in myometrial and leiomyoma cells. Myometrial tissues had a higher amount of arachidonic acid than leiomyoma tissues while leiomyoma tissues had a higher level of linoleic acid than myometrial tissues. Treatment of primary myometrial and leiomyoma cells with eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) reduced the monounsaturated fatty acid (MUFA) content and increased the polyunsaturated fatty acid (PUFA) content in both cell types. Myometrial and leiomyoma cell membranes were in the liquid-crystalline phase, but EPA- and DHA-treated cells had decreased membrane fluidity. While we found no changes in the mRNA expression of ECM components, EPA and DHA treatment reduced levels of ABCG1, ABCA1, and AKAP13 in both cell types. EPA and DHA also reduced FAK and CYP11A1 expression in myometrial cells. The ability of omega-3 fatty acids to remodel membrane architecture and downregulate the expression of genes involved in mechanical signaling and lipid accumulation in leiomyoma cells offers to further investigate this compound as preventive and/or therapeutic option.

AB - A rapidly increasing number of HIV-1 infections have been identified among men who have sex with men (MSM) in Fujian province of China since 2010. We aimed to investigate the causative factors underlying this surging epidemic. Using immunoassays for HIV-1 diagnosis and phylogenetic analysis for viral genotyping, we found that the number of MSM infections doubled from 171 in 2011 to 340 in 2013 with a significantly increased prevalent rate from 4.1% to 5.2%. Majority of these increased infections took place in Fuzhou, Xiamen, and Quanzhou, three large cities in Fujian, mainly among youth, unemployed, business, and well educated MSMs. Phylogenetic analysis revealed three major HIV-1 genotypes including CRF01_AE, CRF07_BC, and B/B' yet the surging MSM infections were primarily associated with the rapid sexual spread of CRF07_BC in addition to CRF01_AE. In particular, there was a significant proportional expansion of CRF07_BC infections among recently infected MSMs from 19% in 2012 to 41.9% in 2013. This increase was accompanied by emergence of complex patterns of viral recombination including multiple hybrid variants derived from CRF01_AE and CRF07_BC. Full-genome analysis indicated that CRF07_BC in Fujian was likely originated from similar strains previously found among IDUs in Yunnan province but with unique recombination break points. Our findings indicated that HIV-1 CRF07_BC has adapted for rapid sexual transmission, resulting in the surging HIV 1 epidemic and the emergence of new recombinant strains among MSMs in Fujian. Our findings have implications to vaccine and passive immunization trials in Fujian with emphasis on the induction of cross-subtype protective immunity.

PMID- 29574776 TI - Brain Monitoring Devices in Neuroscience Clinical Research: The Potential of Remote Monitoring Using Sensors, Wearables, and Mobile Devices. AB - The increasing miniaturization and affordability of sensors and circuitry has led to the current level of innovation in the area of wearable and microsensor solutions for health monitoring. This facilitates the development of solutions that can be used to measure complex health outcomes in nonspecialist and remote settings. In this article, we review a number of innovations related to brain monitoring including portable and wearable solutions to directly measure brain electrical activity, and solutions measuring aspects related to brain function such as sleep patterns, gait, cognition, voice acoustics, and gaze analysis. Despite the need for more scientific validation work, we conclude that there is enough understanding of how to implement these approaches as exploratory tools that may provide additional valuable insights due to the rich and frequent data they produce, to justify their inclusion in clinical study protocols. PMID- 29574777 TI - Doppler Renal Resistance Index for the Prediction of Response to Passive Leg Raising Following Cardiac Surgery. AB - PURPOSE: Doppler-based renal resistance index (RI) can be measured at the bedside of critically ill patients. This study was designed to assess if the RI predicted an increase in cardiac output (CO) following passive leg-raising (PLR) in patients admitted to the intensive care unit after cardiac surgery. METHODS: During this single center prospective study, Doppler assessment of RI and measurements of CO using the thermodilution method were performed, after surgery, in the intensive care unit before and after PLR. A positive response to PLR was defined as a >=10% increase in CO. RESULTS: We included 30 patients. The mean RI was higher before (0.694 +/-0.069) than after PLR (0.679 +/- 0.069) (P = .02) with a median change of -0.012 (IQR: -0.042;0.000). Following PLR, 9 patients (30%) had a >10% increase in CO. In patients with a positive PLR response, the decrease in the RI during PLR was more pronounced than in patients who did not respond to PLR (PLR +/- 0.042 (IQR: -0.051; -0.040) vs PLR +/- -0.008 (IQR: 0.032; 0.015) (P = .004). There was a significant negative association between RI change in response to PLR and a 10% increase in CO following PLR (OR: 1.63 (CI:1.07-2.47) (P = .02) per -0.01 change). CONCLUSION: An increase in CO following PLR was associated with a significant decrease in RI. Variations of RI in response to PLR should be further studied as a tool to predict fluid responsiveness. However, their clinical utility could be limited by the small magnitude of the variations.

PMID- 29574779 TI - A DEAD-box RNA helicase, RH8, is critical for regulation of ABA signalling and the drought stress response via inhibition of PP2CA activity. AB - Abscisic acid (ABA) is major plant hormone involved in regulating abiotic stress responses. Several studies have established that an ABA-signalling transduction pathway-from ABA perception to response-functions in plant cells. The group A PP2Cs constitute core components of ABA signalling, and they negatively regulate ABA signalling and stress responses. Recent studies have identified and functionally analysed regulators of PP2C activity; however, the precise regulatory mechanisms remain unclear. In the present study, we used a yeast 2 hybrid (Y2H) screening analysis to identify the DEAD-box RNA helicase RH8, which interacted with PP2CA in the nucleus. rh8 knockout mutants exhibited ABA hyposensitivity and drought-susceptible phenotypes characterized by high levels of transpirational water loss via reduced stomatal closure and decreased leaf temperatures. However, rh8/pp2ca double mutants showed ABA hypersensitivity and drought-tolerant phenotypes, indicating that RH8 and PP2CA function in the same ABA-signalling pathway in the drought stress response; moreover, RH8 functions upstream of PP2CA. In vitro phosphatase and kinase assays revealed that RH8 inhibits PP2CA phosphatase activity. Our data indicate that RH8 and its interacting partner PP2CA modulate the drought stress response via ABA-dependent signalling. PMID- 29574780 TI - Prevalence of depressive symptoms in older nursing home residents with intact cognitive function in Taiwan. AB - The investigators aimed to explore the prevalence of depressive symptoms and associated factors among older residents with intact cognitive function in nursing homes in Taiwan. A cross-sectional descriptive and correlational research design was used. A convenience sample of 178 older residents without cognitive impairment was recruited from 36 nursing homes in Southern Taiwan. The questionnaires included demographic data; the Barthel Index, which assesses the ability to perform activities of daily living; and the Geriatric Depression Scale Short Form. Among older residents in nursing homes with intact cognitive function, 39.3% had depressive symptoms. Age, religion, previous living status, previous working status, being totally dependent in physical function, and being severely dependent in physical function were significant predictors of depressive symptoms among cognitively intact older residents. The findings highlight the critical mental healthcare issues among older residents with intact cognitive function in nursing homes. Practical strategies for preventing the occurrence of depressive symptoms and caring for those who have depressive symptoms should be developed, especially for younger or dependent older residents or residents who have never been employed, have no religious beliefs, or have lived alone before they moved into an institution. PMID- 29574782 TI - Rab9-dependent autophagy is required for the IGF-IIR triggering mitophagy to eliminate damaged mitochondria. AB - Mitochondria dysfunction is the major characteristic of mitophagy, which is essential in mitochondrial quality control. However, excessive mitophagy contributes to cell death in a number of diseases, including ischemic stroke and hepatotoxicity. Insulin-like growth factor II (IGF-II) and its receptor (IGF-IIR) play vital roles in the development of heart failure during hypertension. We found that IGF-II triggers IGF-IIR receptor activation, causing mitochondria dysfunction, resulting in mitophagy, and cardiomyocyte cell death. These results indicated that IGF-IIR activation triggers mitochondria fragmentation, leading to autophagosome formation, and loss of mitochondria content. These results are associated with Parkin-dependent mitophagy. Additionally, autophagic proteins Atg5, and Atg7 deficiency did not suppress IGF-IIR-induced mitophagy. However, Rab9 knockdown reduced mitophagy and maintained mitochondrial function. These constitutive mitophagies through IGF-IIR activation trigger mitochondria loss and mitochondrial ROS accumulation for cardiomyocyte viability decrease. Together, our results indicate that IGF-IIR predominantly induces mitophagy through the Rab9-dependent alternative autophagy. PMID- 29574781 TI - Time course of cytochrome oxidase blob plasticity in the primary visual cortex of adult monkeys after retinal laser lesions. AB - We studied the time course of changes of cytochrome oxidase (CytOx) blob spatial density and blob cross-sectional area of deprived (D) and nondeprived (ND) portions of V1 in four capuchin monkeys after massive and restricted retinal laser lesions. Laser shots at the border of the optic disc produced massive retinal lesions, while low power laser shots in the retina produced restricted retinal lesions. These massive and restricted retinal lesions were intended to simulate glaucoma and diabetic retinopathy, respectively. We used a Neodymium-YAG dual frequency laser to make the lesions. We measured Layer III blobs in CytOx reacted tangential sections of flat-mounted preparations of V1. The plasticity of the blob system and that of the ocular dominance columns (ODC) varied with the degree of retinal lesions. We found that changes in the blob system were different from that of the ODC. Blob sizes changed drastically in the region corresponding to the retinal lesion. Blobs were larger and subjectively darker above and below the non deprived ODC than in the deprived columns. With restricted lesions, blobs corresponding to the ND columns had sizes similar to those from non-lesioned areas. In contrast, blobs corresponding to the deprived columns were smaller than those from nonlesioned areas. With massive lesions, ND blobs were larger than the deprived blobs. Plastic changes in blobs described here occur much earlier than previously described. PMID- 29574783 TI - Management of unrecognized bladder perforation following suburethral tape procedure. PMID- 29574784 TI - New thermomechanically treated NiTi alloys - a review. AB - In the past 10 years, several proprietary processing procedures for nickel titanium (NiTi) alloy were developed to improve the mechanical properties of NiTi endodontic instruments. Beside specific thermal and mechanical treatments, manufacturers introduced several machining procedures (e.g. twisting, electrical discharge machining), as well as techniques for final surface finishing. NiTi alloys used for endodontic instruments can be subdivided into instruments that mainly contain the austenite phase (austenitic: conventional NiTi, M-Wire, R Phase) and those mainly containing the martensite phase (martensitic: CM Wire, Gold and Blue heat-treated NiTi). Thermomechanically treated NiTi alloys have been reported to be more flexible with improved cyclic fatigue resistance and greater angle of deflection at failure when compared to conventional NiTi. These enhanced properties may be attributed to a modified phase composition containing varying amounts of R-phase and martensite. Endodontic instruments made of austenitic alloys possess superelastic properties because of stress-induced martensite transformation and consequently tend to spring-back to their original form after deformation. In contrast, the martensitic instruments can easily be deformed due to the reorientation of the martensite variants and show a shape memory effect when heated. The use of martensitic alloy results in more flexible instruments, with an increased cyclic fatigue resistance compared with austenitic alloy. PMID- 29574785 TI - Resident alveolar macrophages are master regulators of arrested alveolarization in experimental bronchopulmonary dysplasia. AB - Trophic functions for macrophages are emerging as key mediators of developmental processes, including bone, vessel, and mammary gland development. Yolk sac derived macrophages mature in the distal lung shortly after birth. Myeloid lineage macrophages are recruited to the lung and are activated under pathological conditions. These pathological conditions include bronchopulmonary dysplasia (BPD), a common complication of preterm birth characterized by stunted lung development, where the formation of alveoli is blocked. No study has addressed causal roles for immune cells in lung alveolarization. We employed antibody-based and transgenic death receptor-based depletion approaches to deplete or prevent lung recruitment of immune cell populations in a hyperoxia based mouse model of BPD. Neither neutrophils nor exudate macrophages (which might include lung interstitial macrophages) contributed to structural perturbations to the lung that were provoked by hyperoxia; however, cells of the Csf1r-expressing monocyte/macrophage lineage were implicated as causal mediators of stunted lung development. We propose that resident alveolar macrophages differentiate into a population of CD45+ CD11c+ SiglecF+ CD11b+ CD68+ MHCII+ cells, which are activated by hyperoxia, and contribute to disturbances to the structural development of the immature lung. This is the first report that causally implicates immune cells in pathological disturbances to postnatal lung organogenesis. Copyright (c) 2018 Pathological Society of Great Britain and Ireland.

PMID- 29574787 TI - Multiple drug intolerance syndrome and multiple drug allergy syndrome: Epidemiology and associations with anxiety and depression. AB - BACKGROUND: The epidemiology of multiple drug intolerance syndrome (MDIS) and multiple drug allergy syndrome (MDAS) is poorly characterized. We used electronic health record (EHR) data to describe prevalences of MDIS and MDAS and to examine associations with anxiety and depression. METHODS: Patients with >=3 outpatient encounters at Partners HealthCare System from 2008 to 2015 were included. Patients with MDIS had intolerances to >=3 drug classes, and patients with MDAS had hypersensitivities to >=2 drug classes. Psychiatric conditions and comorbidities were defined from the EHR and used in multivariable logistic regression models to assess the relation between anxiety/depression and MDIS/MDAS. RESULTS: Of 746 888 patients, 47 634 (6.4%) had MDIS and 8615 (1.2%) had MDAS; 3171 (0.4%) had both. Anxiety (adjusted odds ratio [aOR] 1.72 [1.65, 1.80]), depression (aOR 1.46 [1.41, 1.52]), and both anxiety and depression (aOR 1.97 [1.86, 2.08]) were associated with increased odds of MDIS. Depression was associated with increased odds of MDAS (aOR 1.41 [1.28, 1.56]), but there were no clear associations with anxiety (aOR 1.13 [0.99, 1.30]) nor both depression and anxiety (aOR 1.13 [0.92, 1.38]). CONCLUSION: While 6% of patients had MDIS, only 1% had MDAS. MDIS was associated with both anxiety and depression; patients with both anxiety and depression had an almost twofold increased odds of MDIS. MDAS was associated with a 40% increased odds of depression, but there was no significant association with anxiety. Psychological assessments may be useful in the evaluation and treatment of patients with MDIS and MDAS; physiologic causes for MDAS warrant further investigation.

AB - It is widely accepted that development of autoimmunity in the central nervous system (CNS) is triggered by autoreactive T cells, that are activated in the periphery and gain the capacity to migrate through endothelial cells at the blood brain barrier (BBB) into the CNS. Upon local reactivation, an inflammatory cascade is initiated, that subsequently leads to a recruitment of additional immune cells ultimately causing demyelination and axonal damage. Even though the interaction of immune cells with the BBB has been in the focus of research for many years, the exact mechanisms of how immune cells enter and exit the CNS remains poorly understood. In this line, the factors deciding immune cell entry routes, lesion formation, cellular composition as well as distribution within the CNS have also not been elucidated. The following factors have been proposed to represent key determinants for lesion evaluation and distribution: (i) presence and density of (auto) antigens in the CNS, (ii) local immune milieu at sites of lesion development and resolution, (iii) trafficking routes and specific trafficking requirements, especially at the BBB and (iv) characteristics and phenotypes of CNS infiltrating cells and cell subsets (e.g. features of T helper subtypes or CD8 cells). The heterogeneity of lesion development within inflammatory demyelinating diseases remains poorly understood until today, but here especially orphan inflammatory CNS disorders such as neuromyelitis optica spectrum disorder (NMOSD), Rasmussen encephalitis or SUSAC syndrome might give important insights in critical determinants of lesion topography. Finally, investigating the interaction of T cells with the BBB using in vitro approaches or tracking of T cells in vivo in animals or even human patients, as well as the discovery of lymphatic vasculature in the CNS are teaching us new aspects during the development of CNS autoimmunity. In this review, we discuss recent findings which help to unravel mechanisms underlying lesion topography and might lead to new diagnostic or therapeutic approaches in neuroinflammatory disorders including multiple sclerosis (MS). PMID- 29574790 TI - The role of enhancer of zeste homolog 2: From viral epigenetics to the carcinogenesis of hepatocellular carcinoma. AB - Nowadays, epigenetics covers a crucial role in different fields of science. The enhancer of zeste homolog 2 (EZH2), the catalytic subunit of the Polycomb Repressive Complex 2 (PRC2), is a big proponent of how epigenetic changes can affect the initiation and progression of several diseases. Through its catalytic activity, responsible for the tri-methylation of lysine 27 of the histone H3 (H3K27me3), EZH2 is a good target for both diagnosis and therapy of different pathologies. A large number of studies have demonstrated its crucial role in cancer initiation and progression. Nevertheless, only recently its function in virus diseases has been uncovered; therefore, EZH2 can be an important promoter of viral carcinogenesis. This review explores the role of EZH2 in viral epigenetics based on recent progress that demonstrated the role of this protein in virus environment. In particular, the review focuses on EZH2 behavior in Hepatitis B Virus, analyzing its role in the rise of Hepatocellular Carcinoma. PMID- 29574791 TI - Inhibition of human prostate smooth muscle contraction by the LIM kinase inhibitors, SR7826 and LIMKi3. AB - BACKGROUND AND PURPOSE: In men with benign prostatic hyperplasia, increased smooth muscle tone in the prostate may lead to bladder outlet obstruction and subsequent lower urinary tract symptoms. Consequently, medical treatment aims to inhibit prostate smooth muscle contraction. However, the efficacy of the treatment options available is limited, and improved understanding of mechanisms of prostate smooth muscle contraction and identification of new targets for medical intervention are mandatory. Several studies suggest that LIM kinases (LIMKs) promote smooth muscle contraction; however, this has not yet been examined. Here, we studied effects of the LIMK inhibitors on prostate smooth muscle contraction. EXPERIMENTAL APPROACH: Human prostate tissues were obtained from radical prostatectomy. Phosphorylation of cofilin, a LIMK substrate, was examined using a phospho-specific antibody. Smooth muscle contractions were studied in organ bath experiments. KEY RESULTS: Real-time PCR, Western blot and immunofluorescence suggested LIMKs are expressed in smooth muscle cells of prostate tissues. Two different LIMK inhibitors, SR7826 (1 MUM) and LIMKi3 (1 MUM), inhibited contractions of prostate strips, which were induced by electrical field stimulation, alpha1 -adrenoceptor agonists phenylephrine and methoxamine and the TXA2 analogue, U46619. LIMK inhibition in prostate tissues and cultured stromal cells (WPMY-1) was confirmed by cofilin phosphorylation, which was reduced by SR7826 and LIMKi3. In WPMY-1 cells, SR7826 and LIMKi3 caused breakdown of actin filaments and reduced viability. CONCLUSIONS AND IMPLICATIONS: Smooth muscle tone in the hyperplastic human prostate may underlie the effects of LIMKs, which promote contraction. Contraction of prostate strips can be inhibited by small molecule LIMK inhibitors. PMID- 29574792 TI - Reduced Variability to Aspirin Antiplatelet Effect by the Coadministration of Statins in High-Risk Patients for Cardiovascular Disease. AB - We studied the influence of cardiovascular (CV) risk factors, previous CV events, and cotreatments with preventive medicines, on residual platelet thromboxane (TX)B2 production in 182 patients chronically treated with enteric coated (EC) aspirin (100 mg/day). The response to aspirin was also verified by assessing arachidonic acid-induced platelet aggregation and urinary 11-dehydro-TXB2 levels. Residual serum TXB2 levels exceeded the upper limit value for an adequate aspirin response in 14% of individuals. This phenomenon was detected at 12 hours after dosing with aspirin. The coadministration of statins (mostly atorvastatin) was an independent predictor of residual serum TXB2 levels, and the percentage of patients with enhanced values was significantly lower in statin users vs. nonusers. We provide evidence in vitro that atorvastatin reduced residual TXB2 generation by increasing the extent of acetylation of platelet COX-1 by aspirin. In conclusion, the coadministration of statins may counter the mechanisms associated with reduced bioavailability of aspirin detected in some individuals with CV disease. PMID- 29574793 TI - Identifying Human Naive Pluripotent Stem Cells - Evaluating State-Specific Reporter Lines and Cell-Surface Markers. AB - Recent reports that human pluripotent stem cells can be captured in a spectrum of states with variable properties has prompted a re-evaluation of how pluripotency is acquired and stabilised. The latest additions to the stem cell hierarchy open up opportunities for understanding human development, reprogramming, and cell state transitions more generally. Many of the new cell lines have been collectively termed 'naive' human pluripotent stem cells to distinguish them from the conventional 'primed' cells. Here, several transcriptional and epigenetic hallmarks of human pluripotent states in the recently described cell lines are reviewed and evaluated. Methods to derive and identify human naive pluripotent stem cells are also discussed, with a focus on the uses and future developments of state-specific reporter cell lines and cell-surface proteins. Finally, opportunities and uncertainties in naive stem cell biology are highlighted, and the current limitations of human naive pluripotent stem cells considered, particularly in the context of differentiation. PMID- 29574794 TI - Acromegalic cardiomyopathy: Epidemiology, diagnosis, and management. AB - Acromegalic cardiomyopathy is the leading cause of morbidity and all-cause mortality in patients with acromegaly. Though acromegaly is a rare condition, the associated derangements are vast and severe. Stemming from an increase in circulating growth hormone (GH) and insulin-like growth factor-1 levels (IGF-1), acromegalic cardiomyopathy results in pathological changes in myocyte growth and structure, cardiac contractility, and vascular function. These molecular changes manifest commonly as biventricular hypertrophy, diastolic and systolic dysfunction, and valvular regurgitation. Early recognition of the condition is paramount, though the insidious progression of the disease commonly results in a late diagnosis. Biochemical testing, based on IGF-1 measurements, is the gold standard of diagnosis. Management should be centered on normalizing serum levels of both IGF-1 and GH. Transsphenoidal resection remains the most cost-effective and permanent treatment for acromegaly, though medical therapy possesses benefit for those who are not surgical candidates. Ultimately, achieving control of hormone levels results in a severe reduction in mortality rate, underscoring the importance of early recognition and treatment. PMID- 29574795 TI - In-vitro evaluation of accuracy of dynamic contrast-enhanced ultrasound (DCEUS) based parametric perfusion imaging with respiratory motion-compensation. AB - PURPOSE: The accuracy of multi-parametric perfusion imaging (PPI) based on dynamic contrast-enhanced ultrasound is disturbed by the respiratory motion in some cases, especially during characterizing hemodynamic features of abdominal tumor angiogenesis. This study aimed to effectively remove those disturbances on PPI and evaluate its accuracy. METHOD: The respiratory motion-compensation (rMoCo) strategy in PPI was modified by employing non-negative matrix factorization combined with phase-by-phase compensation. According to the known and controllable ground truths in in-vitro perfusion experiments, the accuracy of the modified rMoCo strategy was further evaluated from multiple perspectives in a simulated dual-vessel flow phantom. RESULTS: Compared with that of PPIs without rMoCo, the mean correlation coefficient between six PPIs with rMoCo and the corresponding static PPIs was up to 0.98 +/- 0.01 and improved by 0.17 +/- 0.04 (P < 0.05). The estimated error of vascular diameter decreased from 87.85% (P < 0.05) to 7.25% (P < 0.05) after rMoCo. PPIs with rMoCo were significantly consistent with static PPIs without respiratory motion disturbances. CONCLUSIONS: These quantitative results illustrated the disturbances induced by respiratory motion were effectively removed and the accuracy of PPIs was significantly improved. The partial parabolic and bimodal hemodynamic characteristics and the anatomical structures and sizes were accurately quantified and depicted by PPIs with rMoCo. The modified method can benefit physicians in providing accurate diagnoses and in developing appropriate therapeutic strategies for abdominal diseases. PMID- 29574796 TI - Low-cost biotransformation of glycerol to 1,3-dihydroxyacetone through Gluconobacter frateurii in medium with inorganic salts only. AB - : Existing dihydroxyacetone (DHA) production practices require the use of yeast extracts, leading to relatively high production costs. This study explores the use of low-cost media comprising glycerol, inorganic salts and Gluconobacter frateurii BCC 36199 in the production of DHA. The medium components are also quantitatively optimized. Regression models describing the linear correlations between the nutrient concentrations and the generated DHA concentration (p), and between the nutrient concentrations and the yield (ysp ) are developed. Under the optimal conditions according to our regression models, the highest values for p and ysp are 29.36 g l-1 and 97.86% g g-1 respectively. Quantitatively, this study shows positive effects of inorganic salts and adverse effects of excessive amounts of glycerol on DHA production. In particular, the results suggest that low levels of biomass production lead to high levels of DHA production. Consequently, the media containing inorganic nitrogen source from (NH4 )2 SO4 lead to higher yields than organic media containing yeast extract. This study has identified an optimal, low-cost, minimal medium that can effectively enhance DHA production. SIGNIFICANCE AND IMPACT OF THE STUDY: This study illustrates the advantages of inorganic nutrients supplementation over organic nutrient supplementation for a lower media cost and a higher dihydroxyacetone (DHA) production yield through Gluconobacter frateurii BCC 36199 cultivation. The study found that the use of media that contain only glycerol and inorganic salts enhanced DHA production (DHA-Prod) while keeping the production of bacterial biomass at a sufficient level. Most of the starting material, that is, glycerol, is converted into DHA, which is the target of the production process. The cost of the nitrogen supplement in the DHA-Prod process may be reduced by up to 80% through the use of the inorganic culture medium that has been developed in this study. PMID- 29574797 TI - The antimalarial compound ELQ-400 is an unusual inhibitor of the bc1 complex, targeting both Qo and Qi sites. AB - Inhibitors of the mitochondrial respiratory chain cytochrome bc1 complex, such as the antimalarial atovaquone and ELQ-300, and many well-studied compounds, are classified as either Qo or Qi site inhibitors based on their site of action. Here, we investigated the site of action of ELQ-400 that showed an unusual behaviour, being effective against parasites resistant to the Qo site inhibitor atovaquone or to the Qi site inhibitor ELQ-300. Analysis of yeast mutants and comparison with atovaquone and other ELQs strongly suggest that ELQ-400 targets both Qo and Qi sites. Dual site inhibition would be particularly efficient as it would lower the risk of acquired resistance. However, such compounds are seldom found, which could be explained by structural and mechanistic differences between the sites. PMID- 29574798 TI - Modulation of human dendritic cell activity by Giardia and helminth antigens. AB - Giardia duodenalis is a common intestinal protozoan parasite known to modulate host immune responses, including dendritic cell (DC) function. Coinfections of intestinal pathogens are common, and thus, DCs may be concurrently exposed to antigens from multiple parasites. Here, we investigated the effects of G. duodenalis products on human monocyte-derived DC function independently and in combination with helminth antigens (Ascaris suum and Trichuris suis). All antigens individually induced an anti-inflammatory phenotype in DCs, reducing lipopolysaccharide (LPS)-induced interleukin (IL)-6, IL-12p70 and tumour necrosis factor (TNF)-alpha secretion. G. duodenalis and T. suis products also consistently upregulated IL-10 production. Despite a similar modulation of cytokine secretion, additive effects between Giardia and helminth products were not observed, indicating a dominant effect of a single parasite stimulus and limited interactive effects on DC function. G. duodenalis trophozoites induced rapid apoptosis in DCs, which was not observed with the helminth antigens suggesting that the modulatory effects of G. duodenalis may override that of A. suum and T. suis. Thus, G. duodenalis modulates DC activity by modulating cytokine secretion and/or inducing apoptosis, which may be a parasite-driven mechanism to dampen host immunity and establish chronic infections. The differential mechanisms of DC modulation by intestinal parasites warrant further attention.

PMID- 29574800 TI - High salt-induced excess reactive oxygen species production resulted in heart tube malformation during gastrulation. AB - An association has been proved between high salt consumption and cardiovascular mortality. In vertebrates, the heart is the first functional organ to be formed. However, it is not clear whether high-salt exposure has an adverse impact on cardiogenesis. Here we report high-salt exposure inhibited basement membrane breakdown by affecting RhoA, thus disturbing the expression of Slug/E-cadherin/N cadherin/Laminin and interfering with mesoderm formation during the epithelial mesenchymal transition(EMT). Furthermore, the DiI+ cell migration trajectory in vivo and scratch wound assays in vitro indicated that high-salt exposure restricted cell migration of cardiac progenitors, which was caused by the weaker cytoskeleton structure and unaltered corresponding adhesion junctions at HH7. Besides, down-regulation of GATA4/5/6, Nkx2.5, TBX5, and Mef2c and up-regulation of Wnt3a/beta-catenin caused aberrant cardiomyocyte differentiation at HH7 and HH10. High-salt exposure also inhibited cell proliferation and promoted apoptosis. Most importantly, our study revealed that excessive reactive oxygen species(ROS)generated by high salt disturbed the expression of cardiac-related genes, detrimentally affecting the above process including EMT, cell migration, differentiation, cell proliferation and apoptosis, which is the major cause of malformation of heart tubes.

AB - When primates exhibit hair loss and are observed to engage in self or social hair plucking (a rapid jerking away of the hair shaft and follicle by the hand or mouth, often accompanied by inspection, and consumption) the altered appearance, and behavior patterns are thought to reflect individual physiological, and psychological well-being. Hair loss and hair plucking occur in many captive primate species, including all of the great apes. We present the first survey of this behavior among captive bonobos (N = 88; 50 females and 38 males) in seven zoos in the United States. We found that 43% of the population engaged in this behavior pattern and discounting youngsters (who are not observed to hair pluck until the age of five), 58% of individuals hair plucked. Of the individuals who hair plucked, 97% engaged in social plucking, whereas 46% engaged in self directed plucking. We regressed the occurrence of hair plucking with multiple predictor variables using binary logistic regression and multimodel inference to determine which predictors best explained the prevalence of self-directed and social plucking. We also analyzed publicly available data on hair plucking in captive chimpanzees. We found that the occurrence of another abnormal behavior, age, origin, and pelage condition best explained self-directed plucking in bonobos. Social plucking was explained by age, origin, pelage, and sex. Our analysis of chimpanzee hair plucking revealed that plucking is strongly influenced by rearing and sex. This study demonstrates that hair plucking is more prevalent in captive bonobos compared to captive chimpanzees and gorillas, however, the covariates associated with hair plucking for each species are different. Our data suggest a potential link between self-directed plucking and well-being. However, the higher prevalence and etiology of social hair plucking is more difficult to explain.

Conclusions and perspectives 1337 Acknowledgements 1338 Author contributions 1338 References 1338 SUMMARY: High cellular plasticity confers remarkable regeneration capacity to plants. Based on the activity of stem cells and their regulators, higher plants are capable of regenerating new individuals. De novo organogenesis exemplifies the regeneration of the whole plant body and is exploited widely in agriculture and biotechnology. In this Tansley insight article, we summarize recent advances that facilitate our understanding of the molecular mechanisms underlying de novo organogenesis. According to our current knowledge, this process can be divided into three steps, including activation of regeneration-initial cells, acquisition of competency and de novo establishment of apical meristems. The functions of stem cells and their regulators are critical to de novo organogenesis, whereas auxin and cytokinin act as triggers and linkers between different steps. PMID- 29574803 TI - Preventive effect of polynucleotide on post-thyroidectomy scars: A randomized, double-blinded, controlled trial. AB - BACKGROUND AND OBJECTIVE: Polynucleotide (PN) provides a structural scaffold to induce anti-inflammatory and enhanced wound healing properties, and this study aimed to assess the efficacy of PN administration in the prevention of post operative scars after conventional open total thyroidectomy. STUDY DESIGN MATERIALS AND METHODS: Forty-two patients with thyroid carcinoma who underwent total thyroidectomy were randomly assigned to the study (PN administration) or control (normal saline) group. All patients underwent a single session of combined ablative and non-ablative fractional laser. The Vancouver Scar Scale (VSS), global photographic assessment, and objective scar were assessed using three-dimensional (3D) camera at baseline and at 2, 4, 8, and 16 weeks after surgery. RESULTS: Patients who underwent PN injection demonstrated better surgical scar quality outcome. Participants in the PN administration group had lower VSS scores than the control group (2.09 +/- 0.47 vs. 4.01 +/- 0.55, respectively) and lower scar height (0.23 +/- 0.03 vs. 0.29 +/- 0.03, respectively), as measured using 3D imaging. Furthermore, in the PN injected group, the degree of erythema, and pigmentation of the scar were less prominent. No patient developed hypertrophic scar or keloids on the surgical site. No other adverse events, including post-inflammatory hyperpigmentation, scarring, or infection, were observed. CONCLUSION: Adjuvant administration of PN along with conventional fractional laser treatment led to more favorable effect in wound healing and post-operative scar prevention after thyroidectomy.

AB - WHAT IS KNOWN AND OBJECTIVE: In this study, the effect of carvacrol (CAR) on pulmonary function tests (PFT), haematological indices and oxidant/antioxidant biomarkers in patients with sulphur mustard (SM)-induced lung disorders was examined. METHODS: Twenty patients exposed to SM 27-30 years ago were divided into two groups and treated with either placebo (P) or CAR (1.2 mg/kg per day) (n = 10 for each group). Forced vital capacity (FVC), peak expiratory flow (PEF), total and different white blood cell (WBC), haematological parameters and oxidant/antioxidant biomarkers were measured at the baseline (step 0), one and two months (steps I and II, respectively) after starting the treatment. RESULTS AND DISCUSSION: PEF was significantly increased in the CAR-treated group in step II compared to step 0 (P < .01). Total WBC (P < .01) and neutrophil (P < .05) count in the CAR-treated group were significantly decreased in the group in steps I and II (P < .01 for both cases) compared to step 0. The levels of thiol, superoxide dismutase and catalase in the CAR-treated group were significantly increased (P < .05 to P < .001) in steps I and II, but malondialdehyde significantly decreased in step II compared to step 0 (P < .01). The percentage of total and differential WBC, oxidant/antioxidant biomarkers, FVC and PEF values following a two-month treatment period were significantly improved in the CAR treated group compared to the placebo group (P < .05 to P < .001). WHAT IS NEW AND CONCLUSION: Two-month treatment with CAR reduced inflammatory cells and oxidant biomarkers, whereas increased antioxidant biomarkers and improved PFT tests in SM-exposed patients. PMID- 29574805 TI - Investigation of the Relationship Between Electrical Stimulation Frequency and Muscle Frequency Response Under Submaximal Contractions. AB - Neuromuscular electrical stimulation (NMES) is a common tool that is used in clinical and laboratory experiments and can be combined with mechanomyography (MMG) for biofeedback in neuroprostheses. However, it is not clear if the electrical current applied to neuromuscular tissues influences the MMG signal in submaximal contractions. The objective of this study is to investigate whether the electrical stimulation frequency influences the mechanomyographic frequency response of the rectus femoris muscle during submaximal contractions. Thirteen male participants performed three maximal voluntary isometric contractions (MVIC) recorded in isometric conditions to determine the maximal force of knee extensors. This was followed by the application of nine modulated NMES frequencies (20, 25, 30, 35, 40, 45, 50, 75, and 100 Hz) to evoke 5% MVIC. Muscle behavior was monitored by the analysis of MMG signals, which were decomposed into frequency bands by using a Cauchy wavelet transform. For each applied electrical stimulus frequency, the mean MMG spectral/frequency response was estimated for each axis (X, Y, and Z axes) of the MMG sensor with the values of the frequency bands used as weights (weighted mean). Only with respect to the Z (perpendicular) axis of the MMG signal, the stimulus frequency of 20 Hz did not exhibit any difference with the weighted mean (P = 0.666). For the frequencies of 20 and 25 Hz, the MMG signal displayed the bands between 12 and 16 Hz in the three axes (P < 0.050). In the frequencies from 30 to 100 Hz, the muscle presented a higher concentration of the MMG signal between the 22 and 29 Hz bands for the X and Z axes, and between 16 and 34 Hz bands for the Y axis (P < 0.050 for all cases). We observed that MMG signals are not dependent on the applied NMES frequency, because their frequency contents tend to mainly remain between the 20- and 25-Hz bands. Hence, NMES does not interfere with the use of MMG in neuroprosthesis. PMID- 29574806 TI - Intercountry master's degree in nursing: policy implications for the Mozambican health system. AB - PURPOSE: Within an overarching evaluation framework, this study explored the experiences of course participants and administrators of an intercountry master's degree in nursing between South Africa and Mozambique. The lessons learnt were used to inform nursing and health policy for the Mozambican health system. METHODS: Kirkpatrick's four levels of training evaluation and a results-oriented approach to capacity change were integrated to form a hybrid evaluation framework to capture information about course implementation and the context/environment within which it was delivered. The study used quantitative and qualitative methods including a self-administered survey of course participants, document review, in-depth, semi-structured interviews with course administrators and two focus group discussions with course participants. FINDINGS: Participants enrolled in the course primarily to gain new knowledge and to improve health outcomes; course participants and administrators responded positively to the course design, course implementation and the quality of teaching. Knowledge and skills gained help to build graduates' confidence and boost their attitude towards nursing. Paradoxically, graduates felt powerless to transfer knowledge and effect change in practice. CONCLUSION: This collaborative, capacity development project produced postgraduate nurses in two areas of specialization, namely, critical care and trauma nursing and maternal and neonatal health. While course participants gained significant benefits in new skills and knowledge and a higher degree qualification, the rewards available to them in the public health system remain unclear. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Lessons learnt may serve to influence policy decisions about the role of the Ministry of Health and other stakeholders in sustaining the output and quality of postgraduate nurses for the Mozambican health system. A strategic approach informed by multilevel policies at government, organizational and managerial levels should be adopted to systematically minimize and remove barriers to the transfer and utilization of knowledge and skills in the workplace. PMID- 29574808 TI - Oral Cancer. AB - The management of oral cancer is a multidisciplinary endeavour, as each patient presents the treating clinicians with a unique set of challenges the management of which impacts on both survival and quality of life. This article focuses on the management of oral cancer. We highlight the epidemiology and risk factors for oral cancer in Australia, the various clinical presentations that occur and the staging of oral cancer. In the vast majority of cases surgery remains the mainstay of treatment. Radiation and medical oncology is usually used in an adjuvant context. Dental professionals play a critical role in many stages of management from the initial detection, to optimising pre treatment dental health and managing the short and long term sequelae of treatment. Monitouring for recurrence and the development of second primary tumours is a key role. PMID- 29574807 TI - A glycosyl transferase family 43 protein involved in xylan biosynthesis is associated with straw digestibility in Brachypodium distachyon. AB - The recalcitrance of secondary plant cell walls to digestion constrains biomass use for the production of sustainable bioproducts and for animal feed. We screened a population of Brachypodium recombinant inbred lines (RILs) for cell wall digestibility using commercial cellulases and detected a quantitative trait locus (QTL) associated with this trait. Examination of the chromosomal region associated with this QTL revealed a candidate gene that encodes a putative glycosyl transferase family (GT) 43 protein, orthologue of IRX14 in Arabidopsis, and hence predicted to be involved in the biosynthesis of xylan. Arabinoxylans form the major matrix polysaccharides in cell walls of grasses, such as Brachypodium. The parental lines of the RIL population carry alternative nonsynonymous polymorphisms in the BdGT43A gene, which were inherited in the RIL progeny in a manner compatible with a causative role in the variation in straw digestibility. In order to validate the implied role of our candidate gene in affecting straw digestibility, we used RNA interference to lower the expression levels of the BdGT43A gene in Brachypodium. The biomass of the silenced lines showed higher digestibility supporting a causative role of the BdGT43A gene, suggesting that it might form a good target for improving straw digestibility in crops. PMID- 29574809 TI - The contemporary management of third molars. AB - The management of third molars requires a significant assessment and decision process both for the patient and the clinician. The clinician must always identify the indication for third molar surgery, assess the risks of the proposed procedure, and then modify their plan to account for the patient's current and future health, their social and financial setting, and the patient's tolerance of risk. In doing this, the clinician can tailor a solution to meet the individual patient's needs. This decision to remove a third molar is made in the fluid setting of the patient's quality of life and requires regular review. This article gives the clinician the tools, the matrix, and the confidence to guide patients through this process, and outlines some of the pitfalls and common points of bias within the process. PMID- 29574810 TI - Management of temporomandibular joint disorders: A surgeon's perspective. AB - Disorders of the Temporomandibular joint (TMJ) may clinically present with jaw pain and restricted mouth opening that may limit a patient's access to comprehensive dental care. The aim of this article is to provide a general overview of the current treatment strategies available in the management of disorders of the TMJ. Both conservative and surgical treatment options will be discussed as there is no one treatment for temporomandibular disorders (TMD) which encompasses a wide range of diagnoses. A multidisciplinary team approach to management is essential in the fundamental care of all TMD patients so that treatment can be specifically tailored to individual patient needs. PMID- 29574811 TI - Contemporary exodontia. AB - Exodontia is a cardinal skill of all dentists. Patients expect extractions to be skillfully and painlessly accomplished every time. It's not necessarily so simple and can be challenging. In this paper we explore contemporary issues of the full process of exodontia including diagnosis, technique, complication minimization as well as management of medically compromised patients with appropriate post operative care, including pharmacotherapy. PMID- 29574812 TI - The teaching of oral & maxillofacial surgery to dental students in Australia & New Zealand. AB - The teaching of OMS to dental students in Australia & New Zealand was surveyed. Generally the established schools had well developed curricula with good didactic and clinical experience conducted by specialist OMS educators. There was a much greater array of teaching in some of the newer schools with some appearing to barely meet the current minimalist professional competencies of the ADC. The critical element was whether or not the school was associated with a speciality OMS Unit at a Teaching Hospital. Proposals addressing these deficiencies are presented. PMID- 29574813 TI - Paediatric oral & maxillofacial surgery. AB - Children have differences in their physiology, anatomy and they are continuing to grow and develop. The management of pathology, trauma, deformity and upper airway obstruction in the young growing patient has to take into account these factors in the treatment planning for these conditions. It is important for Oral & Maxillofacial Surgeons to understand the potential impact of disease or injury on the developing facial skeleton and dentition. This chapter will provide an overview of the some of the major components of paediatric maxillofacial surgery and their management. PMID- 29574815 TI - Reconstruction of major defects of the jaws. AB - Prosthetic replacements in the 19th and early 20th century were superseded by pedicled flaps and obturators. These have subsequently been superseded by free tissue transfer which currently is the mainstay of reconstructive jaw surgery. Although malignant and benign processes of the jaws are the predominant cause of segmental defects, a significant proportion still occurs due to trauma, or even iatrogenic causes such as radiotherapy. The varied aetiologies demand a nuanced approach to reconstruction and although the techniques remain similar the timing can be quite different. The maxilla and the mandible are both amenable to composite reconstruction with bone. The fibula, iliac crest, scapula, distal radius and medial femoral condyle are the most commonly utilised donor sites for vascularised reconstruction. Each has strengths and weaknesses and the requirements of the defect, and patient preference should outweigh surgeon preference. Osseointegrated implants allow reliable rehabilitation of the dentition by anchoring facial prostheses. Their integration into composite flaps is highly reliable although soft tissue management can be challenging. Virtual surgical planning and 3D printing have already impacted on the surgical workflow and improved the reliability and accuracy of results. If this technology can be applied to tissue typing and human tissue (instead of just plastic and metal) a fully prefabricated and vascularised jaw without donor site morbidity would be the ultimate aim. PMID- 29574814 TI - Extractions to reconstruction: The Development of Oral & Maxillofacial Surgery in Australian and New Zealand. AB - Oral and Maxillofacial Surgery developed initially from Dentistry as exodontia. It then expanded into the surgical management of jaw disorders. As the specialty evolved, it came into increasing conflict with related surgical disciplines. In the 1960s and 1970s these external criticisms were well-founded as training in oral surgery was individual, solely University-based and highly variable. In the 1980s the speciality developed a plan which involved hospital-based surgical training, a mandatory high level college surgical examination and detailed workforce and training studies. These were progressively implemented over the next twenty years with a dual degree (medicine and dentistry) and a final fellowship (FRACDS (OMS)). This resulted in accreditation by the Australian Medical Council and the Australian Dental Council and recognition as a Principal Surgical Speciality by the Commonwealth Department of Health. This development was monitored by published workforce studies over three decades that are important yardsticks to inform the credentialing of dental specialists. PMID- 29574816 TI - Current and evolving trends in the management of facial fractures. AB - The oral and maxillofacial region has a complex regional anatomy including hard and soft tissues. Trauma in this region may affect the airway, cause potentially life threatening bleeding and head injuries. The senses of olfaction, sight and hearing can also be disrupted as well as a profound psychological impact following disfigurement. This oral and maxillofacial trauma update provides information on demographics, incidence, pathophysiology, diagnosis, fracture patterns and management of facial trauma. It also discusses the role of new advancements in the management of facial trauma. PMID- 29574817 TI - Craniofacial disorders. AB - The complexity of the craniofacial patient mandates the cooperation of a multidisciplinary team that can systematically evaluate each individual and ensure that a protocol-driven pathway is undertaken for the best patient care. Oral and maxillofacial surgeons contribute to surgical care in this setting with specific knowledge of growth and development of the face. This enables optimum timing for early skeletal correction where appropriate, and definitive surgery following the cessation of growth to maximize function and aesthetics. This chapter will describe the major principles in managing patients with specific craniofacial anomalies and provide examples of the outcomes possible.

AB - The atrophic and edentulous jaw can pose a number of challenges for the implant clinician. In simple terms, the amount of bone that remains is insufficient for the conventional placement of a dental implant. A variety of treatment strategies can be employed to enable implants to be placed despite the paucity of bone stock in either the mandible or the maxilla. Conceptually these strategies follow one of two pathways: either augmentation of the bone, or the novel utilization of the remaining bone. This article will discuss patient assessment, treatment planning, and the range of contemporary options available to enable fixed implant based rehabilitation of each jaw.

PMID- 29574820 TI - Implantology in oral & maxillofacial surgery. The complexity of 'simple' cases. AB - Dental implants have been a routine part of dental practice for many years and are performed by a variety of practitioners with different backgrounds and training. This paper will outline the principles and practical surgical aspects of 'simple' implant placement against a background of our current understanding of the literature that informs our surgical procedures. Implants need to be placed in a restoratively suitable position surrounded by sufficient bone, draped in adequate keratinised soft tissue and sufficiently separated from one another and the adjacent teeth. Practically, while the above principles apply, there are nuances based on the local situation, adjacent teeth and restorative needs which will be considered in this paper. Surgery for the placement of implants needs a practitioner with adequate surgical training and experience and who understands the biological aspects and restorative needs of each clinical situation.

AB - BACKGROUND: The aim of this study was the investigation of concentration and prevalence of selected periodontal pathogenic bacteria and concentration of active matrix metalloproteinase-8 (aMMP-8) within a group of patients with inflammatory bowel diseases (IBD) and to compare the results with a group of healthy control subjects (HC). METHODS: Fifty-nine IBD patients with Crohn's disease (CD, n = 30) or ulcerative colitis (UC, n = 29) and 59 HC were included in this cross-sectional study. Based on periodontal probing depth (PD) and clinical attachment level (CAL), periodontitis was classified as healthy/mild, moderate, or severe. aMMP-8 was analyzed from gingival crevicular fluid using enzyme linked immunosorbent assay. Eleven selected periodontal pathogenic bacteria were analyzed in subgingival plaque samples using polymerase chain reaction. RESULTS: IBD patients showed higher CAL (P < 0.01), more severe periodontitis (P = 0.04), gingival bleeding (P < 0.01) and aMMP-8 concentration (P < 0.01) than HC. Only in CD, increasing severity of periodontitis was associated with an increase in aMMP-8 concentration (P = 0.02). The prevalences of Eubacterium nodatum and Eikenella corrodens were significantly lower in IBD compared to HC (P = 0.01). Additionally, the prevalence of Eikenella corrodens was significantly higher in CD compared to the UC group (P = 0.04). Further statistically significant differences in selected bacteria between IBD and HC or CD and UC groups could not be found (P > 0.05). CONCLUSIONS: The results reveal changes in host immune response of IBD patients in terms of aMMP-8. Only in CD increasing aMMP-8 was associated with severity of periodontal disease. The role of periodontal pathogenic bacteria in the interrelationship between IBD and periodontitis remains unclear. PMID- 29574824 TI - An LC-MS/MS method for quantification of demethylzeylasteral, a novel immunosuppressive agent in rat plasma and the application to a pharmacokinetic study. AB - In this study, a sensitive liquid chromatography-tandem mass spectrometry (LC MS/MS) method was developed and validated for the quantification of demethylzeylasteral in rat plasma. Electrospray ionization was operated in the negative ion mode while demethylzeylasteral and oleanolic acid (internal standard) were measured by selected reaction monitoring (demethylzeylasteral: m/z 479.2 -> 436.0; oleanolic acid: m/z 454.9 -> 407.2). This LC-MS/MS method had good selectivity, sensitivity, accuracy and precision. The pharmacokinetic profiles of demethylzeylasteral were subsequently examined in Wistar rats after oral or intravenous administration. PMID- 29574825 TI - Risk factors associated with allergic sensitization and asthma phenotypes among poultry farm workers. AB - BACKGROUND: This study investigated the risk factors for occupational allergic sensitization and various asthma phenotypes in poultry-workers. METHODS: A cross sectional study of 230 workers used a modified ECRHS questionnaire, spirometry, FeNO, Phadiatop, and sIgE to poultry farming related allergens. RESULTS: Worker's mean age was 37 +/- 9 years, 68% male, 43% current-smokers, 34% atopic, and 5% casual-workers. The prevalence of non-atopic asthma (NAA = 7%) was higher than atopic-asthma (AA = 5%) and probable allergic occupational-asthma (OA = 3%). Sensitization to at least one poultry farming related allergen was 24%. Workers sensitized to chicken-specific-allergens were more likely to be atopic (ORunadj = 20.9, 95%CI: 4.7-93.2) or employed as casual-workers (ORunadj = 6.0, 95%CI: 1.1-35.9). Work-related chest symptoms were associated the rearing-department (ORadj = 3.2, 95%CI: 1.2-8.4) and exposure to high gas/dust/fumes (ORadj = 4.8, 95%CI: 2.4-9.5). Airflow reversibility (ORadj = 10.9, 95%CI: 2.0-60.3) was significantly associated with casual-work status. CONCLUSION: Allergic and non allergic mechanisms play a role in asthma development among poultry-workers with casual workers demonstrating increased risk. PMID- 29574827 TI - Addressing the estimation of standard errors in fixed effects meta-analysis. AB - Standard methods for fixed effects meta-analysis assume that standard errors for study-specific estimates are known, not estimated. While the impact of this simplifying assumption has been shown in a few special cases, its general impact is not well understood, nor are general-purpose tools available for inference under more realistic assumptions. In this paper, we aim to elucidate the impact of using estimated standard errors in fixed effects meta-analysis, showing why it does not go away in large samples and quantifying how badly miscalibrated standard inference will be if it is ignored. We also show the important role of a particular measure of heterogeneity in this miscalibration. These developments lead to confidence intervals for fixed effects meta-analysis with improved performance for both location and scale parameters.

AB - High-throughput sequencing of the DNA/RNA encoding antibody heavy- and light chains is rapidly transforming the field of adaptive immunity. It can address key questions, including: (i) how the B-cell repertoire differs in health and disease; and (ii) if it does differ, the point(s) in B-cell development at which this occurs. The advent of technologies, such as whole-genome sequencing, offers the chance to link abnormalities in the B-cell antibody repertoire to specific genomic variants and polymorphisms. Here, we discuss the current research using B cell antibody repertoire sequencing in three polygenic autoimmune diseases where there is good evidence for a pathological role for B-cells, namely systemic lupus erythematosus, multiple sclerosis and rheumatoid arthritis. These autoimmune diseases exhibit significantly skewed B-cell receptor repertoires compared with healthy controls. Interestingly, some common repertoire defects are shared between diseases, such as elevated IGHV4-34 gene usage. B-cell clones have effectively been characterized and tracked between different tissues and blood in autoimmune disease. It has been hypothesized that these differences may signify differences in B-cell tolerance; however, the mechanisms and implications of these defects are not clear. PMID- 29574829 TI - A sort of revolution: Systematics and physical anthropology in the 20th century. AB - During the first four decades of the 20th century, a system of ideas about the evolution and systematics of humans and other primates coalesced around the work of George Gaylord Simpson and W. E. Le Gros Clark. Buttressed by the "new physical anthropology" of the 1950s, that system provided an authoritative model a disciplinary matrix or paradigm-for the practice of that aspect of biological anthropology. The Simpson-Le Gros Clark synthesis began to unravel in the 1960s and collapsed in the 1970s under the onslaught of cladistic systematics. The cladistic "revolution" resembles a paradigm shift of the sort proposed by Thomas Kuhn because it was driven, not by new biological discoveries or theories, but by a change in aesthetics.

AB - BACKGROUND: Familial hypercholesterolemia (FH) is a common autosomal dominant disease associated with premature coronary heart disease (CHD). Studies tend to show that patients with FH associated with an identified mutation (mutation+ FH) are at higher risk than patients without an identified mutation (mutation- FH). We compared the clinical and biological profile and the risk of CHD in patients with mutation+ FH and mutation- FH. HYPOTHESIS: In addition to LDL-C, a pathogenic mutation predicts premature CHD in FH. METHODS: We successively included all patients with suspected FH (LDL-C > 190 mg/dL if age > 18 years; LDL C > 160 mg/dL if age < 18 years) and compared patients with a pathogenic mutation with those without an identified pathogenic mutation. RESULTS: We studied 179 patients with mutation+ FH and 147 with mutation- FH. The mean age was 44 (+/- 18) years. The lipid profile was more atherogenic in those with mutation+ FH, who had higher LDL-C (254 +/- 69 mg/dL vs 218 +/- 35 mg/dL; P < 0.01) and lower HDL-C (53 +/- 14 mg/dL vs 58 +/- 17 mg/dL; P < 0.01). Despite the more atherogenic nonlipid cardiovascular profile of patients with mutation- FH, the age of CHD onset was earlier in patients with mutation+ FH (48 vs 56 years; P = 0.026). After multiple adjustment, the presence of a positive mutation was significantly associated with premature CHD (OR: 3.0, 95% CI: 1.38-6.55, P < 0.01). CONCLUSIONS: Patients with mutation+ FH have a more atherogenic lipid profile and a 3-fold higher risk of premature CHD, as well as earlier onset of CHD, than patients with mutation- FH.

AB - WHAT IS KNOWN AND OBJECTIVE: Dexmedetomidine is a selective alpha-2 agonist used for sedation in the intensive care unit (ICU). CASE DESCRIPTION: A 41-year-old woman intubated in the ICU and being treated for acute respiratory distress syndrome (ARDS) received dexmedetomidine following successful extubation to treat increasing agitation thought to be secondary to a history of polysubstance abuse. Following initiation of the dexmedetomidine, the patient became febrile as well as increasingly more agitated and delirious. All potential fever or delirium causes were evaluated. Following discontinuation of dexmedetomidine, her fever, agitation and delirium ceased. WHAT IS NEW AND CONCLUSION: We depict the first known case of dexmedetomidine causing high fevers and delirium. PMID- 29574852 TI - Early and late implant failure of submerged versus non-submerged implant healing: A systematic review, meta-analysis and trial sequential analysis. AB - INTRODUCTION: The aim of this systematic review was to analyse current evidence regarding differences in early and late implant failure as well as in marginal bone level (MBL) changes between submerged and non-submerged healed dental implants. METHODS: PUBMED, SCOPUS, EMBASE and Web of Science databases were searched for prospective randomized and non-randomized controlled studies addressing direct comparison between submerged and non-submerged implant healing, without performing immediate loading. Early and late implant failure (before or after 6 months from implant placement, respectively) together with MBL were the investigated outcomes. Risk of bias assessment was performed using the Cochrane Collaboration Tool for Randomized clinical trials. Meta-analysis was performed and the power of the meta-analytic findings determined by trial sequential analysis (TSA). RESULTS: Eleven studies met the inclusion criteria and were included in the review. Results of this systematic review revealed a small higher rate (2%) of early implant failure when a non-submerged healing approach is performed. Late implant failure appears not to be different in submerged or non submerged healing, but the power of evidence, as determined by TSA, is not high. If we consider MBL changes at 1 year from implant load, it seems that non submerged healing may better preserve marginal bone, although with a small effect size (0.13 mm). CONCLUSIONS: Implants placed with a non-submerged technique have a higher risk (2%) of early failure. The power of the evidence about the effects on MBL is low, but present results seem to favour non-submerged healing, although with a very small effect size. PMID- 29574853 TI - Prevalence and predictive factors of early postpartum diabetes among women with gestational diabetes in a single-center cohort. AB - OBJECTIVE: To determine the prevalence of diabetes at 6-12 weeks postpartum among women with gestational diabetes mellitus (GDM), and to identify prenatal postpartum diabetes predictors. METHODS: In the present prospective cohort study, glucose statuses of consecutive women newly diagnosed with hyperglycemia during pregnancy were evaluated at 6-12 weeks postpartum between November 1, 2015, and November 1, 2016, at Tygerberg Hospital, Cape Town, South Africa. Women with known diabetes were excluded. RESULTS: There were 78 patients included; 36 (46%) patients had abnormal postpartum glucose values (21 [27%] diabetes; 15 [19%] pre diabetes) and 29 (37%) had overt diabetes in pregnancy. In univariate analyses, GDM diagnosis before 24 weeks of pregnancy (P<0.001), degree of hyperglycemia at diagnosis (P=0.001), need for insulin (P=0.001), glycosylated hemoglobin (HbA1c) in the month preceding delivery (P=0.006), older than 36 years (P=0.039), family history of diabetes (P=0.048), and preterm labor (P=0.039) were risk factors for postpartum diabetes. Multivariate analyses confirmed family history of diabetes (OR 7.45, 95% CI 1.05-52.76; P=0.044), HbA1c at diagnosis (OR 5.33, 95% CI 2.25 12.60; P<0.001), and age (OR 8.8, 95% CI 1.35-58.45; P=0.023), as robust predictors of diabetes after GDM. CONCLUSION: The high prevalence of diabetes supports early postpartum oral glucose tolerance testing. Several women had undiagnosed diabetes. The risk factors identified could be useful for prenatal risk stratification.

AB - : The effects of different setting times (15-120 min) on the rheological properties of cold thickened protein-based beverage (PBB) samples prepared with different xanthan gum (XG)-based food thickeners were examined. In this study, four commercial XG-based food thickeners (coded A-D) and three commercial PBB products (whole milk, skim milk, and soybean milk) were used to prepare thickened PBB samples at a 3% thickener concentration. The fastest increases in etaa,50 values of thickened PBB samples were observed at 15 min, and at longer time periods their etaa,50 values gradually increased or remained constant with an increase in setting time (15-120 min). The magnitudes of the rheological parameters (etaa,50 , K, G', and G") of thickened PBB samples with thickener A were significantly higher compared with those with other thickeners (coded B, C, and D). The flow and dynamic rheological properties of thickened PBB samples prepared with different XG-based thickeners were significantly different (p < .05), demonstrating that their rheological properties were greatly affected by the type of PBB and thickener as well as the setting time. PRACTICAL STATEMENTS: Food thickeners have been commonly used in the preparation of various thickened fluids with desirable rheological properties for dysphagic patients to elicit an optimal swallow response. However, among various thickened fluids, there is limited rheological information on cold thickened protein-based beverage (PBB) (e.g., whole milk, skim milk, and soybean milk) prepared with various xanthan gum (XG)-based thickeners. Our flow and dynamic rheological results showed that the flow and viscoelastic properties of the thickened PBB samples prepared with different food thickeners were dependent on the PBB type, thickener type, and setting time. These rheological results presented in this study will provide both thickener manufacturers and clinicians with valuable information for thickened PBB products with desirable rheological properties for safe and easy swallowing. New knowledge of the different rheological characterizations of thickened PBB can be practically applied to develop the commercial dysphagia thickeners suitable for PBB in food industry.

AB - : This study investigated the occurrence of Escherichia coli pathotypes in sanitary wastewater and drinking water in a Bangladeshi urban slum and the potential associations between these sources. We examined 621 E. coli isolates from sanitary wastewater and stored drinking water by multiplex PCR and dual index sequencing, classifying them into eight pathotypes based on 14 virulence genes and additionally evaluating the possession of the human-specific E. coli genetic biomarker H8. The proportions of pathogenic E. coli were significantly different (P < 0.001) between wastewater (18.6%) and drinking water (1.7%). StIb positive enterotoxigenic E. coli (ETEC) were predominant in wastewater, indicating that people in the site carried ETEC. In contrast, no ETEC was present in drinking water and the proportion of H8-positive isolates was significantly smaller (7.8%) than that in wastewater (16.3%) (P = 0.001). Our findings indicate that sanitary wastewater from the slum was heavily contaminated with pathogenic E. coli, posing a great health risk. Furthermore, E. coli contamination of drinking water could be derived from not only human but also other sources. SIGNIFICANCE AND IMPACT OF THE STUDY: Sanitary wastewater from an urban slum was heavily contaminated with pathogenic Escherichia coli. It is worth noting a great health risk of accidental exposure to pathogenically contaminated wastewater improperly discharged in and around urban slums. The distinct difference in pathotypes between wastewater and drinking water and the significantly smaller positive proportion of the human-specific E. coli genetic biomarker (H8) in drinking water indicate that drinking water contamination could be derived from not only human but also other sources. This highlights that pathotyping in association with the H8 marker provides an indication of pathogen contamination sources of environmental transmission media. PMID- 29574856 TI - HU deviation in lung and bone tissues: Characterization and a corrective strategy. AB - INTRODUCTION: In the era of precision medicine, quantitative applications of x ray Computed Tomography (CT) are on the rise. These require accurate measurement of the CT number, also known as the Hounsfield Unit. In this study, we evaluated the effect of patient attenuation-induced beam hardening of the x-ray spectrum on the accuracy of the HU values and a strategy to correct for the resulting deviations in the measured HU values. MATERIALS AND METHODS: A CIRS electron density phantom was scanned on a Siemens Biograph mCT Flow CT scanner and a GE Discovery 710 CT scanner using standard techniques that are employed in the clinic to assess the HU deviation caused by beam hardening in different tissue types. In addition, an anthropomorphic ATOM adult male upper torso phantom was scanned on the GE Discovery 710 scanner. Various amounts of Superflab bolus material were wrapped around the phantoms to simulate different patient sizes. The mean HU values that were measured in the phantoms were evaluated as a function of the water-equivalent area (Aw ), a parameter that is described in the report of AAPM Task Group 220. A strategy by which to correct the HU values was developed and tested. The variation in the HU values in the anthropomorphic ATOM phantom under different simulated body sizes, both before and after correction, were compared, with a focus on the lung and bone tissues. RESULTS: Significant HU deviations that depended on the simulated patient size were observed. A positive correlation between HU and Aw was observed for tissue types that have an HU of less than zero, while a negative correlation was observed for tissue types with HU values that are greater than zero. The magnitude of the difference increases as the underlying attenuation property deviates further away from that of water. In the electron density phantom study, the maximum observed HU differences between the measured and reference values in the cortical bone and lung materials were 426 and 94 HU, respectively. In the anthropomorphic phantom study, the HU difference was as much as -136.7 +/- 8.2 HU (or -7.6% +/- 0.5% of the attenuation coefficient, AC) in the spine region, and up to 37.6 +/- 1.6 HU (or 17.3% +/- 0.8% of AC) in the lung region between scenarios that simulated normal and obese patients. Our HU correction method reduced the HU deviations to 8.5 +/- 9.1 HU (or 0.5% +/- 0.5%) for bone and to -6.4 +/- 1.7 HU (or -3.0% +/- 0.8%) for lung. The HU differences in the soft tissue materials before and after the correction were insignificant. Visual improvement of the tissue contrast was also achieved in the data of the simulated obese patient. CONCLUSIONS: The effect of a patient's size on the HU values of lung and bone tissues can be significant. The accuracy of those HU values was substantially improved by the correction method that was developed for and employed in this study. PMID- 29574857 TI - Accuracy of Medical Students in Detecting Pleural Effusion Using Lung Ultrasound as an Adjunct to the Physical Examination. AB - OBJECTIVES: This study compared the accuracy of medical students in identifying pleural effusion in hospitalized patients using the physical examination versus lung ultrasound (US). METHODS: Fourth-year medical students (n = 14) received 20 hours of general practical US training (including 2 hours of specialized lung US training) plus theoretical and video documentation. The students used the physical examination alone versus the physical examination plus lung US to document the presence or absence of pleural effusion in the right and left hemithoraces of hospitalized patients (n = 11 patients; 22 hemithoraces examined 544 times in total). The reference standard for identification of pleural effusion was a lung US examination by 2 expert point-of-care sonographers. RESULTS: The odds of correctly identifying the presence versus absence of pleural effusion was 5 times greater with lung US as an adjunct to the physical examination compared to the physical examination alone (odds ratio [OR], 5.1 from multivariate logistic regression; 95% confidence interval, 3.3-8.0). The addition of lung US to the physical examination resulted in an increase in sensitivity from 48% to 90%, in specificity from 73% to 86%, and in accuracy from 60% to 88%. The benefits of using US were greater when pleural effusion was present versus absent (OR, 10.8 versus 2.4) and when examining older versus younger patients (OR, 10.2 versus 2.8). CONCLUSIONS: These results demonstrate that medical students' ability to detect the presence or absence of pleural effusion is superior when using lung US as an adjunct to the physical examination than when using the physical examination alone.

PMID- 29574859 TI - Potential improvements of lung and prostate MLC tracking investigated by treatment simulations. AB - PURPOSE/OBJECTIVES: Intrafraction tumor motion during external radiotherapy is a challenge for the treatment accuracy. A novel technique to mitigate the impact of tumor motion is real-time adaptation of the multileaf collimator (MLC) aperture to the motion, also known as MLC tracking. Although MLC tracking improves the dosimetric accuracy, there are still residual errors. Here, we investigate and rank the performance of five prediction algorithms and seven improvements of an MLC tracking system by extensive tracking treatment simulations. MATERIALS AND METHODS: An in-house-developed MLC tracking simulator that has been experimentally validated against an electromagnetic-guided MLC tracking system was used to test the prediction algorithms and tracking system improvements. The simulator requires a Dicom treatment plan and a motion trajectory as input and outputs all motion of the accelerator during MLC tracking treatment delivery. For lung tumors, MLC tracking treatments were simulated with a low and a high modulation VMAT plan using 99 patient-measured lung tumor trajectories. For prostate, tracking was also simulated with a low and a high modulation VMAT plan, but with 695 prostate trajectories. For each simulated treatment, the tracking error was quantified as the mean MLC exposure error, which is the sum of the overexposed area (irradiated area that should have been shielded according to the treatment plan) and the underexposed area (shielded area that should have been irradiated). First, MLC tracking was simulated with the current MLC tracking system without prediction, with perfect prediction (Perfect), and with the following five prediction algorithms: linear Kalman filter (Kalman), kernel density estimation (KDE), linear adaptive filtering (LAF), wavelet-based multiscale autoregression (wLMS), and time variant seasonal autoregression (TVSAR). Next, MLC tracking was simulated using the best prediction algorithm and seven different tracking system improvements: no localization signal latency (a), doubled maximum MLC leaf speed (b), halved MLC leaf width (c), use of Y backup jaws to track motion perpendicular to the MLC leaves (d), dynamic collimator rotation for alignment of the MLC leaves with the dominant target motion direction (e), improvements 4 and 5 combined (f), and all improvements combined (g). RESULTS: All results are presented as the mean residual MLC exposure error compared to no tracking. In the prediction study, the residual MLC exposure error was 47.0% (no prediction), 45.1% (Kalman), 43.8% (KDE), 43.7% (LAF), 42.1% (wLMS), 40.1% (TVSAR), and 36.5% (Perfect) for lung MLC tracking. For prostate MLC tracking, it was 66.0% (no prediction), 66.9% (Kalman), and 63.4% (Perfect). For lung with TVSAR prediction, the residual MLC exposure error for the seven tracking system improvements was 37.2%(1), 38.3%(2), 37.4%(3), 34.2%(4), 30.6%(5), 27.7%(6), and 20.7%(7). For prostate with no prediction, the residual MLC exposure error was 61.7%(1), 61.4%(2), 55.4%(3), 57.2%(4), 47.5%(5), 43.7%(6), and 38.7%(7). CONCLUSION: For prostate, MLC tracking was slightly better without prediction than with linear Kalman filter prediction. For lung, the TVSAR prediction algorithm performed best. Dynamic alignment of the collimator with the dominant motion axis was the most efficient MLC tracking improvement except for lung tracking with the low modulation VMAT plan, where jaw tracking was slightly better. PMID- 29574860 TI - A dietary pattern based on estrogen metabolism is associated with breast cancer risk in a prospective cohort of postmenopausal women. AB - Increased exposure to estrogen is a risk factor for postmenopausal breast cancer, and dietary factors can influence estrogen metabolism. However, studies of diet and breast cancer have been inconclusive. We developed a dietary pattern associated with levels of unconjugated estradiol and the ratio of 2- and 16 hydroxylated estrogen metabolites in a subsample of Prostate, Lung, Colorectal and Ovarian Screening Trial (PLCO) participants (n = 653) using reduced rank regression, and examined its association with postmenopausal breast cancer prospectively in the larger PLCO cohort (n = 27,488). The estrogen-related dietary pattern (ERDP) was comprised of foods with positively-weighted intakes (non-whole/refined grains, tomatoes, cruciferous vegetables, cheese, fish/shellfish high in omega-3 fatty acids, franks/luncheon meats) and negatively weighted intakes (nuts/seeds, other vegetables, fish/shellfish low in omega-3 fatty acids, yogurt, coffee). A 1-unit increase in the ERDP score was associated with an increase in total (HR: 1.09, 95% CI: 1.01-1.18), invasive (HR: 1.13; 95% CI: 1.04-1.24) and estrogen receptor (ER)-positive (HR: 1.13, 95% CI: 1.02-1.24) breast cancer risk after adjustment for confounders. Associations were observed for the fourth quartile of ERDP compared with the first quartile for overall breast cancer (HR: 1.14; 95% CI: 0.98-1.32), invasive cases (HR: 1.20, 95% CI: 1.02-1.42) and ER-positive cases (HR: 1.19; 95% CI: 0.99-1.41). The increased risk associated with increasing ERDP score was more apparent in strata of some effect modifiers (postmenopausal hormone therapy non-users and non-obese participants) where the relative estrogen exposure due to that factor was lowest, although the p values for interaction were not statistically significant. Results suggest a dietary pattern based on estrogen metabolism is positively associated with postmenopausal breast cancer risk, possibly through an estrogenic influence. PMID- 29574861 TI - Updated Retrospective Single-Center Comparative Analysis of Peripheral Nerve Block Complications Using Landmark Peripheral Nerve Stimulation Versus Ultrasound Guidance as a Primary Means of Nerve Localization. AB - OBJECTIVES: The purpose of this study was to perform an updated analysis of complications associated with upper and lower extremity peripheral nerve blocks (PNBs) performed with ultrasound (US) guidance versus the landmark approach. METHODS: We conducted a single-center retrospective cohort analysis to compare the incidence of PNB complications between the techniques. The primary outcome was local anesthetic systemic toxicity (LAST), whereas the secondary outcomes included short- and long-term nerve injuries. The current query included cases performed between 2012 and 2015. A combined analysis included data extending to 2006. The Statistical examination relied on the chi2 test. RESULTS: During this 4 year period, we performed 7789 US-guided and 498 landmark-guided blocks with no statistically significant difference in the incidence of nerve injury or LAST between the groups. Our 10-year analysis, however, revealed a significant increase (P < .01) in the rate of LAST with the landmark technique: 7 of 5932 versus 0 of 16,858 cases. The combined data also revealed a significant increase (P < .01) in short-term injuries associated with the landmark approach (30 of 5932 versus 33 of 16,858) but no significant difference in the incidence of long term injuries. CONCLUSIONS: Our analysis supports a conclusion that the use of US guidance during PNBs leads to a significant reduction in the incidence of LAST, adding to growing evidence from similar investigations. The impact of US on the incidence of nerve injuries remains unclear, considering that the nature of transient deficits is thought to be multifactorial, and the frequency of lasting injuries did not differ significantly in this study. PMID- 29574862 TI - High amplitude and low frequency cyclic mechanical strain promotes degeneration of human nucleus pulposus cells via the NF-kappaB p65 pathway. AB - Disc degeneration alters the structure and function of intervertebral discs and is the basis of spinal degenerative diseases. To establish the molecular mechanism of intervertebral disc degeneration caused by mechanical strain, this study examined the effects of different amplitude (3%, 9%, 19%) cyclic mechanical strain (CMS) at a low frequency (0.01 Hz) on the secretion of cartilage extracellular matrix, expression of inflammatory cytokines and catabolic proteases, and activation of NF-kappaB signaling pathway in human nucleus pulposus cells. We also investigated effects of low frequency and high amplitude (19%) CMS on degeneration of human nucleus pulposus cells in the presence or absence of p65 inhibitor, p65 silencing shRNA, or p65 overexpression. While 3% CMS did not significantly decrease aggrecan or type II collagen expression, or increase TNF-alpha, IL-1beta, IL-6 expression, 9% and 19% CMS showed the significant effects. Low frequency and high amplitude (19%) CMS was found to promote p65 activation in human nucleus pulposus cells, and IL-1beta was found to promote p65 nuclear translocation though IkappaB kinase phosphorylation. Furthermore, degeneration process of nucleus pulposus cells was found attenuated in the presence of p65 inhibitor or p65 silencing shRNA, but promoted with p65 overexpression. These data suggest that high amplitude and low frequency CMS could promote degeneration of human nucleus pulposus cells significantly via the NF-kappaB p65 pathway. Our findings have uncovered the effect of CMS on human nucleus pulposus cell degeneration and have identified a previously unknown intrinsic underlying mechanism.

PMID- 29574863 TI - Deciphering the molecular mechanism and apoptosis underlying the in-vitro and in vivo chemotherapeutic efficacy of vanadium luteolin complex in colon cancer. AB - : The present study is carried out to reveal the chemotherapeutic effects of vanadium luteolin complex against HT-29 human colon carcinoma cell line and chemically induced rat colon carcinoma. Our investigation revealed that the vanadium luteolin complex induces apoptosis in HT-29 cells in a dose-dependent manner. Furthermore, the study also confirmed that the vanadium luteolin complex increased caspase-3 and p53 expression whereas reduced the VEGF, mTOR, Akt expression, and induced DNA fragmentation in HT-29 cells. The oral acute and sub acute toxicity and the DNA binding efficacy of the complex with CT-DNA were investigated. The vanadium luteolin complex showed mortality at a dose of 120 mg/kg dose. The sub-acute toxicity of the complex at the dose of 90 mg/kg presented an increased level of WBC count, total bilirubin, ALT, AST, ALP, creatinine, blood urea nitrogen, and decreased level of total protein compared with the control group. Histopathological alterations in kidney, liver, stomach, and lungs was observed at a dose of 90 mg/kg of the complex. The dose of 45 mg/kg of the complex was found to have better chemotherapeutic activity by significantly reducing the incidences of aberrant crypt foci formation, upregulation in the expression of p53 and Bax, and downregulation of the expression of Bcl2, and cell proliferation was found in the complex at a dose of 45 mg/kg. Our findings from the study support that the complex possesses a potential chemotherapeutic activity against colon cancer and was efficient in reducing aberrant crypt foci formation multiplicity, hyperplastic lesions in the colon tissues of rats by inducing apoptosis. SIGNIFICANCE: The present study demonstrates that the effect of vanadium-luteolin complex in HT-29 cells and dimethylhydrazine challenged rats, curtail cell proliferation through induction of apoptosis mediated via activation of the key proteins involved in the intrinsic pathway like p53, Bax, caspase-3 and downregulating Bcl2, mTOR/Akt, angiogenic factor VEGF along with aberrant crypt foci formation multiplicity, and PCNA in the colon mucosa. Our combinatorial approach shows higher efficacy at considerably lower doses minimizing side effects. Insights into in-vitro and in vivo results provide strong proof that low dose chemotherapeutic regimens can suppress, reverse, or delay the progression of colon cancer by modulating intrinsic apoptotic as well as antiangiogenic pathways. PMID- 29574866 TI - Surgical treatment of peri-implantitis using enamel matrix derivative, an RCT: 3- and 5-year follow-up. AB - OBJECTIVE: To assess the clinical and radiographic outcomes 3 and 5 years after the surgical treatment of peri-implantitis per se or in combination with an enamel matrix derivative (EMD). MATERIALS AND METHODS: At baseline, 29 patients were randomized to surgical treatment with adjunctive EMD or no EMD. One year after the surgical treatment of peri-implantitis, 25 patients remained eligible for survival analyses at the 3- and 5-year follow-up. The primary outcomes were implant loss and bone level (BL) change measured on radiographs, and the secondary outcomes, bleeding on probing, pus and plaque at each implant were analysed in 18 and 14 patients at the 3- and 5-year follow-up, respectively. RESULTS: After exclusion of four patients who discontinued the study, at the 3 year follow-up, 13 (100%) implants survived in the EMD group, and 10 of 12 (83%) in the non-EMD group. At the 5-year follow-up, 11 of 13 (85%) implants in the EMD group and nine of 12 (75%) in the non-EMD group survived. In multivariate modelling, BL changes and EMD treatment were positively associated with implant survival. Similarly, the same trend was seen in univariate analysis. CONCLUSIONS: An exploratory analysis suggests that adjunctive EMD is positively associated with implant survival up to 5 years, but larger studies are needed. PMID- 29574865 TI - Rheumatologic complications in a cohort of 227 patients with common variable immunodeficiency. AB - Common variable immunodeficiency (CVID) is the most prevalent symptomatic type of human primary immunodeficiency diseases (PID). Clinically, CVID is characterized by increased susceptibility to infections and a wide variety of autoimmune and rheumatologic disorders. All patients with CVID registered in Iranian PID Registry (IPIDR) were enrolled in this retrospective cohort study. We investigated the frequency of rheumatologic diseases and its association with immunological and clinical phenotypes in patients with CVID. A total of 227 patients with CVID were enrolled in this study. The prevalence of rheumatologic disorders was 10.1% with a higher frequency in women than men. Most common rheumatologic manifestations were juvenile idiopathic arthritis (JIA) and adult rheumatoid arthritis (RA) followed by juvenile spondyloarthritis (JSpA) and undifferentiated inflammatory arthritis (UIA). Septic arthritis in patients with CVID with a history of RA and JIA was higher than patients without rheumatologic complication. Patients with CVID with a history of autoimmunity (both rheumatologic and non-rheumatologic autoimmunity) had lower regulatory T cells counts in comparison with patients without autoimmune disorders. There was an association between defect in specific antibody responses and negative serologic test results in patients with rheumatologic manifestations. JIA, RA, JSpA and UIA are the most frequent rheumatologic disorders in patients with CVID. Due to antibody deficiency, serologic tests may be negative in these patients. Therefore, these conditions pose significant diagnostic and therapeutic challenges for immunologists and rheumatologists in charge of the care for these patients. PMID- 29574868 TI - Corrigendum.

AB - Irinotecan (CPT11) and Oxaliplatin have been used in combination with fluorouracil and leucovorin for treating colorectal cancer. However, the efficacy of these drugs is reduced due to various side effects and drug resistance. Fisetin, a hydroxyflavone possess anti-proliferative, anti-cancer, anti inflammatory, and antioxidant activity against various types of cancers. Apart from that, fisetin has been shown to induce cytotoxic effects when combined with other known chemotherapeutic drugs. In this study, we aimed to investigate whether Fisetin was capable of sensitizing both Irinotecan and Oxaliplatin resistance colon cancer cells and explored the possible signaling pathways involved using In vitro and In vivo models. The results showed that Fisetin treatment effectively inhibited cell viability and apoptosis of CPT11-LoVo cells than Oxaliplatin (OR) and parental LoVo cancer cells. Western blot assays suggested that apoptosis was induced by fisetin administration, promoting Caspase 8, and Cytochrome-C expressions possibly by inhibiting aberrant activation of IGF1R and AKT proteins. Furthermore, fisetin inhibited tumor growth in athymic nude mouse xenograft model. Overall, our results provided a basis for Fisetin as a promising agent to treat parental as well as chemoresistance colon cancer.

AB - OBJECTIVES: We sought to confirm retrospective studies that measured an approximately 20% reduction in emergency department (ED) length of stay (LOS) in early-gestation pregnant women who receive emergency physician-performed point-of care ultrasound (US) examinations rather than radiology department-performed US examinations for evaluation of intrauterine pregnancy (IUP). METHODS: A randomized controlled clinical trial was performed at an urban academic safety net hospital and 2 Naval medical centers in the United States. The allocation was concealed before enrollment. Clinically stable adult pregnant women at less than 20 weeks' gestation who presented to the ED with abdominal pain or vaginal bleeding were randomized to receive a point-of-care or radiology US to assess for IUP. The primary outcome measure was the ED LOS. RESULTS: A total of 224 patients (point-of-care US, n = 118; radiology US, n = 106) were included for the analysis. The ED LOS was 20 minutes shorter in the point-of-care US arm (95% confidence interval [CI], -54 to 7 minutes). Adjusting for variability due to the location, the ED LOS was calculated to be 31 minutes shorter (95% CI, -64 to 1 minute) than for patients in the radiology US arm. Excluding patients in the point-of-care US arm who crossed over to radiology US after an inconclusive point of-care US examination, the ED LOS was 75 minutes shorter than in the radiology US arm (95% CI, -97 to -53 minutes). CONCLUSIONS: Early-gestation pregnant ED patients requiring pelvic US were discharged earlier when point-of-care US was used rather than radiology US; however, this trial did not achieve our target of 30 minutes. Nevertheless, our data support the routine use of ED point-of-care US for IUP, saving the most time if a conclusive IUP is identified.

AB - A plethora of developmental and physiological processes in land plants is influenced by auxin, to a large extent via alterations in gene expression by AUXIN RESPONSE FACTORs (ARFs). The canonical auxin transcriptional response system is a land plant innovation, however, charophycean algae possess orthologues of at least some classes of ARF and AUXIN/INDOLE-3-ACETIC ACID (AUX/IAA) genes, suggesting that elements of the canonical land plant system existed in an ancestral alga. We reconstructed the phylogenetic relationships between streptophyte ARF and AUX/IAA genes and functionally characterized the solitary class C ARF, MpARF3, in Marchantia polymorpha. Phylogenetic analyses indicate that multiple ARF classes, including class C ARFs, existed in an ancestral alga. Loss- and gain-of-function MpARF3 alleles result in pleiotropic effects in the gametophyte, with MpARF3 inhibiting differentiation and developmental transitions in multiple stages of the life cycle. Although loss-of function Mparf3 and Mpmir160 alleles respond to exogenous auxin treatments, strong miR-resistant MpARF3 alleles are auxin-insensitive, suggesting that class C ARFs act in a context-dependent fashion. We conclude that two modules independently evolved to regulate a pre-existing ARF transcriptional network. Whereas the auxin-TIR1-AUX/IAA pathway evolved to repress class A/B ARF activity, miR160 evolved to repress class C ARFs in a dynamic fashion. PMID- 29574880 TI - Cannabidiol exerts antiepileptic effects by restoring hippocampal interneuron functions in a temporal lobe epilepsy model. AB - BACKGROUND AND PURPOSE: A non-psychoactive phytocannabinoid, cannabidiol (CBD), shows promising results as an effective potential antiepileptic drug in some forms of refractory epilepsy. To elucidate the mechanisms by which CBD exerts its anti-seizure effects, we investigated its effects at synaptic connections and on the intrinsic membrane properties of hippocampal CA1 pyramidal cells and two major inhibitory interneurons: fast spiking, parvalbumin (PV)-expressing and adapting, cholecystokinin (CCK)-expressing interneurons. We also investigated whether in vivo treatment with CBD altered the fate of CCK and PV interneurons using immunohistochemistry. EXPERIMENTAL APPROACH: Electrophysiological intracellular whole-cell recordings combined with neuroanatomy were performed in acute brain slices of rat temporal lobe epilepsy in in vivo (induced by kainic acid) and in vitro (induced by Mg2+ -free solution) epileptic seizure models. For immunohistochemistry experiments, CBD was administered in vivo (100 mg.kg-1 ) at zero time and 90 min post status epilepticus, induced with kainic acid. KEY RESULTS: Bath application of CBD (10 MUM) dampened excitability at unitary synapses between pyramidal cells but enhanced inhibitory synaptic potentials elicited by fast spiking and adapting interneurons at postsynaptic pyramidal cells. Furthermore, CBD restored impaired membrane excitability of PV, CCK and pyramidal cells in a cell type-specific manner. These neuroprotective effects of CBD were corroborated by immunohistochemistry experiments that revealed a significant reduction in atrophy and death of PV- and CCK-expressing interneurons after CBD treatment. CONCLUSIONS AND IMPLICATIONS: Our data suggest that CBD restores excitability and morphological impairments in epileptic models to pre epilepsy control levels through multiple mechanisms to reinstate normal network function. PMID- 29574881 TI - Low-grade intraductal carcinoma of the salivary gland with prominent oncocytic change: a newly described variant. AB - AIMS: Low-grade intraductal carcinoma (LG-IDC) is a clinically indolent malignant tumour of the salivary glands. Because of its rarity, the histological variants of LG-IDC have not been well characterised. Herein, we describe five LG-IDC cases with prominent oncocytic change in the major salivary glands. METHODS AND RESULTS: We examined five cases, three males and two females (mean age = 63 years), of LG-IDC with oncocytic change. The sites affected by LG-IDC were the parotid and submandibular glands. The lesions were macroscopically unilocular or multilocular cysts with a solid tumour arising from the cyst wall. Smaller tumour cell nests were also observed. As with classic LG-IDC, the cyst wall was surrounded by myoepithelial cells with no invasive component. The tumour cells had abundant oncocytic cytoplasm and proliferated in a low-papillary, tubular or cribriform pattern. Immunohistochemically, the tumour cells were diffusely positive for pan-cytokeratin, S100, mammaglobin and antimitochondria antibody, and were negative for androgen receptor and gross cystic disease fluid protein 15. Unlike classic LG-IDC, some of these cases demonstrated focal invagination of myoepithelial cells in the intraductal tumour. CONCLUSION: Oncocytic LG-IDC should be recognised as a histologically unique variant of LG-IDC. Awareness of this entity is important to avoid erroneous diagnosis and inappropriate treatment for histological mimics. PMID- 29574882 TI - Prevalence and risk factors for myopia and other refractive errors in an adult population in southern India. AB - PURPOSE: To investigate prevalence and risk factors for myopia, hyperopia and astigmatism in southern India. METHODS: Randomly sampled villages were enumerated to identify people aged >=40 years. Participants were interviewed for socioeconomic and lifestyle factors and attended a hospital-based ophthalmic examination including visual acuity measurement and objective and subjective measurement of refractive status. Myopia was defined as spherical equivalent (SE) worse than -0.75 dioptres (D), hyperopia as SE >=+1D and astigmatism as cylinder <-0.5. RESULTS: The age-standardised prevalences of myopia, hyperopia and astigmatism were 35.6% (95% CI: 34.7-36.6), 17.0% (95% CI: 16.3-17.8) and 32.6 (29.3-36.1), respectively. Of those with myopia (n = 1490), 70% had advanced cataract. Of these, 79% had presenting visual acuity (VA) less than 6/18 and after best correction, 44% of these improved to 6/12 or better and 27% remained with VA less than 6/18. In multivariable analyses (excluding patients with advanced cataract), increasing nuclear opacity score, current tobacco use, and increasing height were associated with higher odds of myopia. Higher levels of education were associated with increased odds of myopia in younger people and decreased odds in older people. Increasing time outdoors was associated with myopia only in older people. Increasing age and female gender were associated with hyperopia, and nuclear opacity score, increasing time outdoors, rural residence and current tobacco use with lower odds of hyperopia. After controlling for myopia, factors associated with higher odds of astigmatism were age, rural residence, and increasing nuclear opacity score and increasing education with lower odds. CONCLUSIONS: In contrast to high-income settings and in agreement with studies from low-income settings, we found a rise in myopia with increasing age reflecting the high prevalence of advanced cataract. PMID- 29574883 TI - Physiological stress response patterns during a blood donation. AB - BACKGROUND: Donating blood is associated with increased psychological stress. This study investigates whether a blood donation induces physiological stress and if response patterns differ by gender, donation experience and non-acute stress. STUDY DESIGN AND METHODS: In 372 donors, physiological stress [blood pressure, pulse rate, pulse rate variability (PRV)] was measured at seven moments during routine donation. PRV was assessed using time domain [root mean square of successive differences (RMSSD)] and frequency domain [high frequency (HF) and low frequency (LF) power] parameters. Non-acute stress was assessed by questionnaire. Shape and significance of time course patterns were assessed by fitting multilevel models for each stress measure and comparing men and women, first-time and experienced donors, and donors with high and low levels of non-acute stress. RESULTS: Significant response patterns were found for all stress measures, where levels of systolic blood pressure (F(1,1315) = 24.2, P < 0.001), RMSSD (F(1,1315) = 24.2, P < 0.001), LF (F(1,1627) = 14.1, P < 0.001) and HF (F(1,1624) = 34.0, P < 0.001) increased towards needle insertion and then decreased to values lower than when arriving at the donation centre. Diastolic blood pressure (F(1,1326) = 50.9, P < 0.001) increased and pulse rate (F(1,1393) = 507.4, P < 0.001) showed a U-shaped curve. Significant group effects were found, that is, higher systolic blood pressure/pulse rate in women; higher pulse rate in first-time donors; higher RMSSD at arrival and from screening until leaving in first-time donors; and higher LF and HF in first-time donors. CONCLUSION: This study shows an increase in physiological stress related to needle insertion, followed by a decrease when leaving the donation centre. Some group effects were also found. PMID- 29574884 TI - Progress in the genetics of autism spectrum disorder. AB - : A genetic basis for autism spectrum disorder (ASD) is now well established, and with the availability of high-throughput microarray and sequencing platforms, major advances have been made in our understanding of genetic risk factors. Rare, often de novo, copy number and single nucleotide variants are both implicated, with many ASD-implicated genes showing pleiotropy and variable penetrance. Additionally, common variants are also known to play a role in ASD's genetic etiology. These new insights into the architecture of ASD's genetic etiology offer opportunities for the identification of molecular targets for novel interventions, and provide new insight for families seeking genetic counselling. WHAT THE PAPER ADDS: A number of rare genetic variants are implicated in autism spectrum disorder (ASD), with some showing recurrence. Common genetic variants are also important and a number of loci are now being uncovered. Genetic testing for individuals with ASD offers the opportunity to identify relevant genetic etiology. PMID- 29574885 TI - Cholinergic innervation of principal neurons in the cochlear nucleus of the Mongolian gerbil. AB - Principal neurons in the ventral cochlear nucleus (VCN) receive powerful ascending excitation and pass on the auditory information with exquisite temporal fidelity. Despite being dominated by ascending inputs, the VCN also receives descending cholinergic connections from olivocochlear neurons and from higher regions in the pontomesencephalic tegmentum. In Mongolian gerbils, acetylcholine acts as an excitatory and modulatory neurotransmitter on VCN neurons, but the anatomical structure of cholinergic innervation of gerbil VCN is not well described. We applied fluorescent immunohistochemical staining to elucidate the development and the cellular localization of presynaptic and postsynaptic components of the cholinergic system in the VCN of the Mongolian gerbil. We found that cholinergic fibers (stained with antibodies against the vesicular acetylcholine transporter) were present before hearing onset at P5, but innervation density increased in animals after P10. Early in development cholinergic fibers invaded the VCN from the medial side, spread along the perimeter and finally innervated all parts of the nucleus only after the onset of hearing. Cholinergic fibers ran in a rostro-caudal direction within the nucleus and formed en-passant swellings in the neuropil between principal neurons. Nicotinic and muscarinic receptors were expressed differentially in the VCN, with nicotinic receptors being mostly expressed in dendritic areas while muscarinic receptors were located predominantly in somatic membranes. These anatomical data support physiological indications that cholinergic innervation plays a role in modulating information processing in the cochlear nucleus. PMID- 29574886 TI - Patient characteristics associated with peglyated interferon alfa-2a induced neutropenia in chronic hepatitis C patients. AB - Neutropenia is a haematologic disorder commonly reported in patients with chronic hepatitis C virus (HCV) infection treated with pegylated interferon alfa-2a (PEG IFN alpha-2a). The objective of the present project is to identify patient characteristics associated with neutropenia in hepatitis C patients. Demographic, clinical, and genetic data from 715 patients with chronic HCV infection treated with PEG-IFN alpha-2a and ribavirin. The outcome variable was the development of grade 3 or 4 neutropenia, defined as the decrease in neutrophil counts below 1 109 /L anytime during study. Predictors of neutropenia were identified using a 2 stage approach. First, univariate analysis was performed to identify possible predictors of neutropenia. T test was used for continuous variables and Fisher's exact test was used for categorical variables. Second, multiple logistic regression with stepwise addition was then performed using predictors identified in the univariate analysis step to produce final model containing independent predictors at P < .05. Logistic regression identified female gender, absolute neutrophils counts, and cholesterol level as the main predictors of neutropenia. Female gender increases the odds of experiencing neutropenia by 86% compared to male gender. A 1 unit (mmol/L) increase in cholesterol level decreases the odds of developing neutropenia by 13%. A 55% reduction in the likelihood of developing neutropenia for a 1 unit (109 /L) increase in the absolute neutrophils counts. Patients with high risk of developing neutropenia can be identified. Identification of this cohort allows early intervention to prevent neutropenia. Possible intervention is to administer drugs that raise neutrophil count such as filgrastim before neutropenia occurs. PMID- 29574887 TI - Is exercise stress echocardiography useful in patients with suspected obstructive coronary artery disease who have resting left bundle branch block? AB - BACKGROUND: Current guidelines support exercise stress echocardiography (ESE) for evaluation of suspected obstructive coronary artery disease (OCAD) in ambulant patients with left bundle branch block (LBBB). Data regarding the diagnostic utility of ESE in patients with LBBB are limited. HYPOTHESIS: We hypothesized that the diagnostic performance of ESE for the assessment of suspected OCAD is reduced in the context of LBBB. METHODS: We studied 191 consecutive patients with resting LBBB undergoing ESE for the investigation of suspected OCAD between 2008 and 2015 at our center. The studies were categorized as inconclusive, normal, or abnormal. Patients with an abnormal response were subcategorized as regional ischemic response or globally abnormal. RESULTS: Eighty-two patients (43%) demonstrated a normal left ventricular contractile response (LVCR) to exercise; 92 (48%) developed an abnormal LVCR to exercise, including 70 patients with globally abnormal and 22 patients with regional ischemic responses. Of the patients with abnormal responses, 62 patients had anatomic imaging, only 29 of whom had significant OCAD, conferring an overall specificity of ESE for significant OCAD of 21% and accuracy of 52%. Of patients who developed a regionally abnormal response, 89% had significant OCAD. CONCLUSIONS: For patients with LBBB who develop a globally abnormal LVCR during ESE, the specificity of ESE for reliably excluding significant OCAD is significantly reduced. ESE appears to be a suboptimal test for the evaluation of OCAD in patients with resting LBBB, as about 50% of patients will have an abnormal response, the majority due to globally abnormal contraction where OCAD cannot be reliably diagnosed. Alternative testing should be considered for the investigation of suspected OCAD in patients with resting LBBB. PMID- 29574888 TI - Corticosteroid therapy in pneumonia from swine-origin influenza A (H1N1) in China. AB - The first three cases of confirmed infection with the virus in China were documented between May 10 and May 15, 2009. Although the clinical characteristics of the H1N1 pneumonia were described in clinical reports, the therapy has few been described. Therefore, we report our experiences of 53 cases of the H1N1 pneumonia with treatment. We describe clinical characteristic of 53 patients who were hospitalized for laboratory-confirmed H1N1 pneumonia at the 2nd Clinical College of Harbin Medical University. In addition, we measure the role of corticosteroid, mechanical ventilation, and non-corticosteroid antiviral therapy in the management of pneumonia patients with novel H1N1 infection. Real-time reverse-transcriptase-polymerase chain (RT-PCR) testing was used to confirm infection. The outcome of therapy was compared in scores of PaO2 and CT. The data was statistical analyzed by the Shapiro-Wilk, anova, Student-Newman-Keuls Test, and Kruskal-Wallis Test. The most common symptoms were dyspnea. In moderate ill patients, the changes in the increased PaO2 were lower in the non-corticosteroid antiviral therapy group than in the combination of corticosteroid and non corticosteroid antiviral therapy after 5 days' therapy. The therapy protocol of non-corticosteriod + mechanical ventilation played important role in the recovery of severe ill patients. PMID- 29574889 TI - System for image-guided resection of nonpalpable breast lesions: Proof of concept. AB - PURPOSE: In breast-conserving surgery (BCS), the cancer is sometimes incompletely excised, leading to reduced patient survival. To pursue complete excisions, radioactive seed localization (RSL) may be used to insert an iodine-125 seed into the tumor. The seed is used as a marker for the location of the tumor during surgery. RSL does not, however, show the extent of the tumor. Based on RSL, we pursue to visualize the seed location together with the extent from diagnostic images. METHODS: A system with two gamma-camera heads and two parallel-hole collimators was recently proposed to triangulate the location of an iodine-125 seed during BCS. In the present study, this system was extended with a range camera to visualize a sphere centered on the seed in relation to the breast. This sphere contains the entire tumor and thus defines the target volume for BCS. Physical experiments with acrylic block phantoms (thickness ranging from 3.5 to 6.5 cm) were performed to assess the absolute bias and the precision with which this sphere can be visualized. RESULTS: When a 6.5 cm thick phantom was used, along the horizontal plane, the target volume was visualized with an absolute bias and a precision of 2.1 and 0.8 mm, respectively. Along the vertical axis (i.e., z-axis), these values were 4.2 and 2.8 mm, respectively. CONCLUSIONS: The proposed system visualizes the target volume with an absolute bias that may be acceptable for BCS. PMID- 29574890 TI - Revision of Corallinaceae (Corallinales, Rhodophyta): recognizing Dawsoniolithon gen. nov., Parvicellularium gen. nov. and Chamberlainoideae subfam. nov. containing Chamberlainium gen. nov. and Pneophyllum. AB - A multi-gene (SSU, LSU, psbA, and COI) molecular phylogeny of the family Corallinaceae (excluding the subfamilies Lithophylloideae and Corallinoideae) showed a paraphyletic grouping of six monophyletic clades. Pneophyllum and Spongites were reassessed and recircumscribed using DNA sequence data integrated with morpho-anatomical comparisons of type material and recently collected specimens. We propose Chamberlainoideae subfam. nov., including the type genus Chamberlainium gen. nov., with C. tumidum comb. nov. as the generitype, and Pneophyllum. Chamberlainium is established to include several taxa previously ascribed to Spongites, the generitype of which currently resides in Neogoniolithoideae. Additionally we propose two new genera, Dawsoniolithon gen. nov. (Metagoniolithoideae), with D. conicum comb. nov. as the generitype and Parvicellularium gen. nov. (subfamily incertae sedis), with P. leonardi sp. nov. as the generitype. Chamberlainoideae has no diagnostic morpho-anatomical features that enable one to assign specimens to it without DNA sequence data, and it is the first subfamily to possess both Type 1 (Chamberlainium) and Type 2 (Pneophyllum) tetra/bisporangial conceptacle roof development. Two characters distinguish Chamberlainium from Spongites: tetra/biasporangial conceptacle chamber diameter (<300 MUm in Chamberlainium vs. >300 MUm in Spongites) and tetra/bisporangial conceptacle roof thickness (<8 cells in Chamberlainium vs. >8 cells in Spongites). Two characters also distinguish Pneophyllum from Dawsoniolithon: tetra/bisporangial conceptacle roof thickness (<8 cells in Pneophyllum vs. >8 cells in Dawsoniolithon) and thallus construction (dimerous in Pneophyllum vs. monomerous in Dawsoniolithon).

PMID- 29574892 TI - Codability of industry and occupation information from cancer registry records: Differences by patient demographics, casefinding source, payor, and cancer type. AB - INTRODUCTION: Industry and occupation (I&O) information collected by cancer registries is useful for assessing associations among jobs and malignancies. However, systematic differences in I&O availability can bias findings. METHODS: Codability by patient demographics, payor, identifying (casefinding) source, and cancer site was assessed using I&O text from first primaries diagnosed 2011-2012 and reported to California Cancer Registry. I&O were coded to a U.S. Census code or classified as blank/inadequate/unknown, retired, or not working for pay. RESULTS: Industry was codable for 37% of cases; 50% had "unknown" and 9% "retired" instead of usual industry. Cases initially reported by hospitals, covered by preferred providers, or with known occupational etiology had highest codable industry; cases from private pathology laboratories, with Medicaid, or diagnosed in outpatient settings had least. Occupation results were similar. CONCLUSIONS: Recording usual I&O for retirees and improving linkages for reporting entities without patient access would improve I&O codability and research validity. PMID- 29574893 TI - Adverse drug event profile associated with pregabalin among patients with and without cancer: analysis of a spontaneous reporting database. AB - WHAT IS KNOWN AND OBJECTIVE: Pregabalin is used for the relief of neuropathic pain in patients with and without cancer. However, no report has examined whether there is a difference in the adverse drug event (ADE) profile of pregabalin in each context. We aimed to establish whether pregabalin's ADE profile was different between patients with and without cancer. This study was based on the Japanese Adverse Drug Event Report (JADER) database, which is a spontaneous reporting database. METHOD: Reports obtained from the JADER database were analysed from April 2004 to December 2016 for ADEs, using reporting odds ratios (RORs), a method of disproportionality analysis. We evaluated the association between the RORs and ADEs of pregabalin and compared the age, dosage and time at which ADEs occurred in patients with and without cancer. The primary outcome was RORs. Secondary outcomes were expression age and time-to-onset of ADE among patients with and without cancer. RESULTS AND DISCUSSION: In total, 426 216 reports from the JADER database were analysed. The major side effects associated with pregabalin among both patient groups were interstitial pneumonia, renal failure, liver failure, altered consciousness, heart failure and rhabdomyolysis. The pregabalin dose was significantly higher in patients with cancer than in those without cancer. Furthermore, the times to reporting of interstitial pneumonia, altered consciousness and liver failure were significantly shorter in patients with cancer than in those without cancer. WHAT IS NEW AND CONCLUSION: The ADE profiles of pregabalin were broadly similar among patients with and without cancer, but time-to-onset and type of some ADEs may be different. PMID- 29574894 TI - Irreproducible text-book "knowledge": The effects of color bands on zebra finch fitness. AB - Many fields of science-including behavioral ecology-currently experience a heated debate about the extent to which publication bias against null findings results in a misrepresentative scientific literature. Here, we show a case of an extreme mismatch between strong positive support for an effect in the literature and a failure to detect this effect across multiple attempts at replication. For decades, researchers working with birds have individually marked their study species with colored leg bands. For the zebra finch Taeniopygia guttata, a model organism in behavioral ecology, many studies over the past 35 years have reported effects of bands of certain colors on male or female attractiveness and further on behavior, physiology, life history, and fitness. Only eight of 39 publications presented exclusively null findings. Here, we analyze the results of eight experiments in which we quantified the fitness of a total of 730 color-banded individuals from four captive populations (two domesticated and two recently wild derived). This sample size exceeds the combined sample size of all 23 publications that clearly support the "color-band effect" hypothesis. We found that band color explains no variance in either male or female fitness. We also found no heterogeneity in color-band effects, arguing against both context and population specificity. Analysis of unpublished data from three other laboratories strengthens the generality of our null finding. Finally, a meta analysis of previously published results is indicative of selective reporting and suggests that the effect size approaches zero when sample size is large. We argue that our field-and science in general-would benefit from more effective means to counter confirmation bias and publication bias. PMID- 29574895 TI - "Not such a kid thing anymore": Young adults' perspectives on transfer from paediatric to adult cardiology care. AB - BACKGROUND: Transfer of adolescents with congenital heart disease from paediatric cardiology providers to specialized adult congenital heart disease (ACHD) care providers is becoming a standard practice. However, some paediatric cardiologists continue to provide care for their patients into adult life. Little is known about the perspectives of young adult patients who have been transferred to ACHD clinics versus those who continue to receive their cardiology care in paediatric settings. METHODS: Content and thematic analysis of structured telephone interviews with 21 young adults age 18-25 (13 transferred to ACHD clinic and 8 who had not transferred) was conducted to identify similarities and differences in patient characteristics of those in ACHD versus paediatric settings. RESULTS: There were no appreciable differences in gender, age, heart disease type, and independence between those transferred to ACHD care versus those not transferred. Participants in both groups were aware of differences between the paediatric and ACHD care settings and providers, with some favouring the familiarity offered by the paediatric setting and providers. Participants had varying views on parental involvement in their care; most of them had attended clinic appointments on their own. Those who had transferred to ACHD care acknowledged that it would take time to adjust to new relationships. Positive perspectives on actual or anticipated transfer to ACHD care included a growing sense of autonomy and responsibility, as well as access to reproductive information relevant to ACHD patients. CONCLUSIONS: The absence of patient characteristics distinguishing those in ACHD care versus those still followed in paediatric care suggests that system, provider, and parent factors, rather than patient factors, may account for patients' perspectives on transfer to ACHD care. PMID- 29574896 TI - Resident hesitation in the operating room: does uncertainty equal incompetence? AB - CONTEXT: In postgraduate medical programmes, the progressive development of autonomy places residents in situations in which they must cope with uncertainty. We explored the phenomenon of hesitation, triggered by uncertainty, in the context of the operating room in order to understand the social behaviours surrounding supervision and progressive autonomy. METHODS: Nine surgical residents and their supervising surgeons at a Canadian medical school were selected. Each resident-supervisor pair was observed during a surgical procedure and subsequently participated in separate post-observation, semi-structured interviews. Constructivist grounded theory was used to guide the collection and analysis of data. RESULTS: Three hesitation-related themes were identified: the principle of progress; the meaning of hesitation, and the judgement of competence. Supervisors and residents understood hesitation in the context of a core surgical principle we termed the 'principle of progress'. This principle reflects the supervisors' and residents' shared norm that maintaining progress throughout a surgical procedure is of utmost importance. Resident hesitation was perceived as the first indication of a disruption to this principle and was therefore interpreted by supervisors and residents alike as a sign of incompetence. This interpretation influenced the teaching-learning process during these moments when residents were working at the edge of their abilities. CONCLUSIONS: The principle of progress influences the meaning of hesitation which, in turn, shapes judgements of competence. This has important implications for teaching and learning in direct supervision settings such as surgery. Without efforts to change the perception that hesitation represents incompetence, these potential teaching-learning moments will not fully support progressive autonomy. PMID- 29574897 TI - IL-6 increases podocyte motility via MLC-mediated focal adhesion impairment and cytoskeleton disassembly. AB - The disturbance of podocyte motility is an essential pathogenic mechanisms of foot process effacement during proteinuric diseases, and myosin light chain (MLC) is a pivotal component in regulating the motility of podocytes. Inflammatory cytokine interleukin-6 (IL-6) has been reported to induce podocyte abnormalities by various mechanisms, however, whether aberrant cell motility contributes to the IL-6-induced podocyte injury remains unknown. Here, by wound healing, transwell, and cell migration assays, we confirmed that IL-6 accelerates the motility of podocyte. Simultaneously, the phosphorylation of MLC is elevated along with perturbed focal adhesion (FAs) and cytoskeleton. Next, via genetic and pharmacologic interruption of MLC or its phosphorylation we revealed that the activation of MLC is implicated in IL-6-mediated podocyte hypermotility as well as the disassembly of FAs and F-actin. By using stattic, an inhibitor for STAT3 phosphorylation, we uncovered that STAT3 activation is the upstream event for MLC phosphorylation and the following aberrant motility of podocytes. Additionally, we found that calcitriol markedly attenuates podocyte hypermotility via blocking STAT3-MLC. In conclusion, our study demonstrated that IL-6 interrupts FAs dynamic, cytoskeleton organization, and eventually leads to podocyte hypermotility via STAT3/MLC, whereas calcitriol exerts its protective role by inhibiting this pathway. These findings enrich the mechanisms accounting for IL-6 mediated podocyte injury from the standpoint of cell motility and provide a novel therapeutic target for podocyte disorders. PMID- 29574898 TI - The frequency and management of seizures during psychological treatment among patients with psychogenic nonepileptic seizures and epilepsy. AB - OBJECTIVE: Growing evidence suggests that psychological treatments are effective for improving outcomes in both epilepsy and psychogenic nonepileptic seizures (PNES). However, the risk of in-session seizures may cause concerns about safety and about seizures disrupting treatment. This study explores the risk of in session seizures in patients with epilepsy and those with PNES, the timings of seizures during psychological therapy, and the responses of therapists to seizures. METHODS: Consecutive patients with epilepsy or PNES attending 2 neurology centers in the United Kingdom for psychological treatment to help with their seizure disorders were studied. Information about seizures during outpatient psychological therapy sessions was gathered using a 12-item pro forma. RESULTS: Ninety-seven patients with epilepsy and 195 with PNES were evaluated. One in 32 patients with epilepsy and 1 in 8 with PNES had at least 1 in-session seizure. A seizure occurred in 1 in 136 treatment sessions provided to patients with epilepsy, and 1 in 36 sessions provided to those with PNES. The risk of in session seizures was significantly greater in patients with PNES than in patients with epilepsy (odds ratio [OR] 4.4, 95% confidence interval [CI] 1.3-15.2). Seizures tended to occur in the first half of treatment programs and individual sessions and only disrupted sessions briefly. Only one patient with PNES required in-patient observation not involving overnight admission. SIGNIFICANCE: In session seizures do occur and are much more common in patients with PNES than in those with epilepsy. Seizures rarely caused major disruption to psychological treatment, and could almost invariably be managed by the treating therapist without help from additional medical staff. Nonetheless, this research suggests that psychological therapy providers should anticipate the occurrence of in session seizures and have safe management plans in place.

AB - Structure is an important clinical marker of tendon health; however, current standards use qualitative scores that are not strongly reliable. Therefore, the purpose of this study was to establish the reliability of an image-processing technique that quantifies tendon collagen structure using B-mode ultrasound images. Longitudinal images of the Achilles tendon were collected in 12 healthy young adults, and intra- and inter-rater reliability was assessed over multiple image selections and multiple days. Intraclass correlation coefficients were strong (r >= 0.71) for all comparisons. These findings demonstrate that quantitative assessments of tendon structure using B-mode ultrasound are reliable. PMID- 29574901 TI - Effects of organ motion on proton prostate treatments, as determined from analysis of daily CT imaging for patient positioning. AB - PURPOSE: We quantified interfractional movements of the prostate, seminal vesicles (SVs), and rectum during computed tomography (CT) image-guided proton therapy for prostate cancer and studied the range variation in opposed lateral proton beams. MATERIALS/METHODS: We analyzed 375 sets of daily CT images acquired throughout the proton therapy treatment of ten patients. We analyzed daily movements of the prostate, SVs, and rectum by simulating three image-matching strategies: bone matching, prostate center (PC) matching, and prostate-rectum boundary (PRB) matching. In the PC matching, translational movements of the prostate center were corrected after bone matching. In the PRB matching, we performed PC matching and correction along the anterior-posterior direction to match the boundary between the prostate and the rectum's anterior region. In each strategy, we evaluated systematic errors (Sigma) and random errors (sigma) by measuring the daily movements of certain points on each anatomic structure. The average positional deviations in millimeter of each point were determined by the Van Herk formula of 2.5Sigma + 0.7sigma. Using these positional deviations, we created planning target volumes of the prostate and SVs and analyzed the daily variation in the water equivalent length (WEL) from the skin surface to the target along the lateral beam directions using the density converted from the daily CT number. Based on this analysis, we designed prostate cancer treatment planning and evaluated the dose volume histograms (DVHs) for these strategies. RESULTS: The SVs' daily movements showed large variations over the superior inferior direction, as did the rectum's anterior region. The average positional deviations of the prostate in the anterior, posterior, superior, inferior, and lateral sides (mm) in bone matching, PC matching, and PRB matching were (8.9, 9.8, 7.5, 3.6, 1.6), (5.6, 6.1, 3.5, 4.5, 1.9), and (8.6, 3.2, 3.5, 4.5, 1.9) (mm), respectively. Moreover, the ones of the SV tip were similarly (22.5, 15.5, 11.0, 7.6, 6.0), (11.8, 8.4, 7.8, 5.2, 6.3), and (9.9, 7.5, 7.8, 5.2, 6.3). PRB matching showed the smallest positional deviations at all portions except for the anterior portion of the prostate and was able to markedly reduce the positional deviations at the posterior portion. The averaged WEL variations at the distal and proximal sides of planning target volumes were estimated 7-9 mm and 4-6 mm, respectively, and showed the increasing of a few millimeters in PC and PRB matching compared to bone matching. In the treatment planning simulation, the DVH values of the rectum in PRB matching were reduced compared to those obtained with other matching strategies. CONCLUSION: The positional deviations for the prostate on the posterior side and the SVs were smaller by PRB matching than the other strategies and effectively reduced the rectal dose. 3D dose calculations indicate that PRB matching with CT image guidance may do a better job relative to other positioning methods to effectively reduce the rectal complications. The WEL variation was quite large, and the appropriate margin (approx. 10 mm) must be adapted to the proton range in an initial planning to maintain the coverage of target volumes throughout entire treatment. PMID- 29574902 TI - FOXO1 regulates VEGFA expression and promotes angiogenesis in healing wounds. AB - Angiogenesis is a critical aspect of wound healing. We investigated the role of keratinocytes in promoting angiogenesis in mice with lineage-specific deletion of the transcription factor FOXO1. The results indicate that keratinocyte-specific deletion of Foxo1 reduces VEGFA expression in mucosal and skin wounds and leads to reduced endothelial cell proliferation, reduced angiogenesis, and impaired re epithelialization and granulation tissue formation. In vitro FOXO1 was needed for VEGFA transcription and expression. In a porcine dermal wound-healing model that closely resembles healing in humans, local application of a FOXO1 inhibitor reduced angiogenesis. This is the first report that FOXO1 directly regulates VEGFA expression and that FOXO1 is needed for normal angiogenesis during wound healing.

PMID- 29574904 TI - Respiratory disease and sero-epidemiology of respiratory pathogens in the working horses of Ethiopia. AB - BACKGROUND: Pathogens are frequently implicated in equine respiratory disease. In Ethiopia, respiratory disease is a frequent cause for presentation at veterinary clinics and a priority concern for users of working horses. However, there is little existing literature on possible aetiologies. OBJECTIVES: Determine prevalence of respiratory signs and exposure to major respiratory pathogens through a serological survey. STUDY DESIGN: Cross-sectional. METHODS: Systematically selected horses from 19 sites in central Ethiopia were examined clinically and sampled once (August-December 2013). A face-to-face interview collected data on horses' management and history. Serological testing targeted equine influenza virus (EIV), equine herpesviruses-1 (EHV-1) and -4 (EHV-4), equine rhinitis viruses A (ERAV) and B (ERBV), equine arteritis virus (EAV) and Streptococcus equi subspecies equi (S. equi). RESULTS: Owners reported a recent history of coughing in 38% of horses and nasal discharge in 7%. No animals were observed coughing during examination but 6% had a nasal discharge. Antibodies towards S. equi, were most prevalent (8%, 33/350). Antibodies to EAV were confirmed in one animal (0.3%). Low antibody titres to EHV-1/4 and ERA/BV suggested prior exposure but antibodies to EIV were not detected. Multivariable, multilevel logistic regression analysis for risk factors associated with S. equi serostatus showed higher odds of seropositivity in younger animals and those working less frequently. MAIN LIMITATIONS: A single serological sample cannot describe dynamic changes in antibodies. Sampling horses at the place of work may result in healthy-worker bias. CONCLUSIONS: S. equi may be endemic in this population and contributing, in part, to the occurrence of respiratory disease. Low prevalence of antibodies to viruses, with the exception of EIV, indicates these pathogens are present, but unlikely a predominant cause of respiratory signs and noninfectious causes of disease should also be investigated. Working horses in this region would be vulnerable to incursion of equine influenza. PMID- 29574905 TI - Parents' perceptions of the long-term appropriateness of a psychosocial intervention for children with attention deficit hyperactivity disorder. AB - BACKGROUND/AIM: Designing psychosocial interventions that parents perceive as appropriate is essential to enhancing their engagement with the intervention and their long-term use of the intervention strategies. The aim of this study was to explore the long-term appropriateness of a play-based psychosocial intervention for children with Attention Deficit Hyperactivity Disorder (ADHD) from the perspectives of parents. METHODS: Semi-structured phone interviews were conducted with 14 parents of children with ADHD who participated in a randomised controlled trial of the play-based intervention 1 year earlier. RESULTS: Thematic analysis led to the development of three core-themes: (i) Everybody needs a parenting handbook, (ii) No one thing you are dealing with, and (iii) A different approach: Reframing. DISCUSSION: The core-themes related back to a definition of intervention appropriateness that acknowledges the intervention as important/relevant, beneficial, socially and ecologically valid and promotes sustainable change, indicating parents perceived the intervention as appropriate. The core-themes also resembled aspects of the process of family adaptation. Findings highlight the importance of designing interventions that are appropriate from parents' perspectives to enhance their long-term engagement and use of the intervention strategies as well as outcomes for their child in the long term. PMID- 29574906 TI - The in vitro antimicrobial evaluation of commercially essential oils and their combinations against acne. AB - OBJECTIVE: The study investigated the efficacy of commercial essential oil combinations against the two pathogens responsible for acne with the aim to identify synergy and favourable oils to possibly use in a blend. MATERIALS AND METHODS: Antimicrobial activity was assessed using the minimum inhibitory concentration (MIC) assay against Staphylococcus epidermidis (ATCC 2223) and Propionibacterium acnes (ATCC 11827), and the fractional inhibitory concentration index (SigmaFIC) was calculated. Combinations displaying synergistic interactions were further investigated at varied ratios and the results plotted on isobolograms. RESULTS: From the 408 combinations investigated, 167 combinations were identified as displaying noteworthy antimicrobial activity (MIC value <=1.00 mg mL-1 ). Thirteen synergistic interactions were observed against S. epidermidis, and three synergistic combinations were observed against P. acnes. It was found that not one of the synergistic interactions identified were based on the combinations recommended in the layman's aroma-therapeutic literature. Synergy was evident rather from leads based on antimicrobial activity from previous studies, thus emphasizing the importance of scientific validation. Leptospermum scoparium J.R.Forst. and G.Forst (manuka) was the essential oil mostly involved in synergistic interactions (four) against S. epidermidis. Cananga odorata (Lam.) Hook.f. and Thomson (ylang ylang) essential oil was also frequently involved in synergy where synergistic interactions could be observed against both pathogens. The combination with the lowest MIC value against both acne pathogens was Vetiveria zizanioides Stapf (vetiver) with Cinnamomum verum J.Presl (cinnamon bark) (MIC values 0.19-0.25 mg mL-1 ). Pogostemon patchouli Benth. (patchouli), V. zizanioides, C. verum and Santalum spp. (sandalwood) could be identified as the oils that contributed the most noteworthy antimicrobial activity towards the combinations. The different chemotypes of the essential oils used in the combinations predominantly resulted in similar antimicrobial activity. CONCLUSIONS: The investigated essential oil combinations resulted in at least 50% of the combinations displaying noteworthy antimicrobial activity. Most of the synergistic interactions do not necessarily correspond to the recommended layman's aroma-therapeutic literature, which highlights a need for scientific validation of essential oil antimicrobial activity. No antagonism was observed. PMID- 29574907 TI - Inventing a new measurement for inhibitory control in preschoolers. AB - One of the most prominent tasks to measure spatial-conflict inhibitory control in preschoolers is the windows task (Russell et al., 1991, Br. J. Dev. Psychol., 9, 331). However, this task has been criticized given its high demands on abilities other than inhibition. The aim of the current set of studies was to establish the 'car task' as a novel instrument to assess conflict inhibition in children. In this task, children are asked to point at the current location of an occluded object. To do so, they have to inhibit a misleading colour cue in front of the locations in critical trials. In Study 1, we demonstrated that 3- to 6-year-old children's (N = 88) performance in the car task correlated positively with that in the windows task (even after controlling for age). Study 2 investigated whether children's failure in the car task might be caused by their inability to master the basic processes involved in the task rather than a lack of inhibition. We presented a new group of preschoolers (N = 85) with a modified version of the task without any misleading colour cues. Performance significantly improved, indicating that the difficulty of the car task lies in the necessity to inhibit the misleading colour cue leading towards the incorrect location. These findings suggest that the car task is a valid measurement of spatial-conflict inhibition in children. Statement of contribution What is already known on this subject? Inhibitory control (IC) is important for action planning and execution. One of the most prominent measurements of spatial-conflict IC is the windows task. This task has been criticized for additionally requiring rule inference to succeed. What does this study adds? Performance in the novel car task correlates with that in the windows task. Study 2 controls for demands other than IC such as memory or task difficulty. This task can thus be used to measure IC more purely without demanding rule inference. PMID- 29574908 TI - Peroxisome proliferator-activated receptor gamma plays dual roles on experimental periodontitis in rats. AB - AIM: To investigate the effects of peroxisome proliferator-activated receptor gamma (PPARgamma) on inflammation control and bone remodelling in experimental periodontitis in rats. MATERIALS AND METHODS: Experimental periodontitis was induced in rats by thread ligation around cervixes of mandibular first molars. PPARgamma agonist, antagonist and vehicle were intraperitoneally administrated, respectively, into rats. Ninety-six male SD rats were randomly divided into control, ligation + vehicle, ligation + agonist and ligation + antagonist groups. After 1, 4 and 8 weeks, alveolar bone loss was assessed by Micro-CT and HE staining. Inflammation and bone metabolism factors were evaluated by ELISA and immunohistochemical examination. Osteoclasts were quantified by tartrate resistant acid phosphatase (TRAP) staining. RESULTS: Alveolar bone loss was significantly reduced after 1 week, while significantly increased after 8 weeks in agonist group, but antagonist group showed the opposite trend. Agonist decreased some inflammatory cytokines expression after 1 and 4 weeks, downregulated OPG, RUNX2, BMP-2 and upregulated RANKL after 8 weeks, but antagonist brought the opposite effect. PPARgamma agonist significantly reduced osteoclast counting after 1 week, while increased it after 8 weeks. CONCLUSIONS: During periodontitis progression, PPARgamma could inhibit inflammation, prevent bone resorption within a short time, while the long-term PPARgamma activation would lead to increased bone resorption, and PPARgamma repression by antagonist would enhance alveolar bone formation. PMID- 29574909 TI - Iron status in relation to cancer risk and mortality: Findings from a population based prospective study. AB - While experimental evidence suggests potential carcinogenic effects of increased iron load, there is a lack of data on iron status and cancer risk from epidemiological studies. Here, we evaluated prediagnostic serum concentrations of ferritin, iron and transferrin as well as transferrin saturation (TSAT) in relation to cancer risk and mortality in a prospective study by multivariable Cox regression analyses. A case-cohort sample of the population-based EPIC-Heidelberg Study including a random subcohort (n = 2738) and incident cases of breast cancer (n = 627), prostate cancer (n = 554), lung cancer (n = 195), colorectal cancer (n = 256) and cancer death (n = 759) was used. Ferritin levels were inversely associated with breast cancer risk in the multivariable Cox regression model, with a hazard ratio (HR) of 0.67 [95% confidence interval: 0.49, 0.92] for women in the highest quartile compared to those in the lowest quartile. Neither ferritin nor the other markers of iron status were significantly associated with colorectal, prostate or lung cancer risk. An inverse association was observed between ferritin and total cancer mortality (HR: 0.70 [0.53, 0.92]). There were no significant overall associations between serum iron, transferrin or TSAT and cancer mortality. The present findings do not support the notion of increased iron load constituting a cancer risk factor in the general population. By contrast, our analyses revealed inverse associations between ferritin levels and breast cancer risk as well as cancer mortality. PMID- 29574910 TI - Contemporary Definitions of Suicidal Behavior: A Systematic Literature Review. AB - To address the lack of comparability around the world, we conducted a systematic review of existing definitions of suicide and suicidal behaviors. In the literature, four key features appear to cover the vast majority of concepts underpinning definitions: agency, knowledge of a potential fatal outcome, intent, and outcome. Intent and outcome appear to be the most consensual features of definitions of suicide, albeit revealing interesting conceptual variations. The four key features could be used to devise a research tool able to explore the meanings of suicide across different countries and different cultures. PMID- 29574911 TI - Long noncoding RNAs in cancer-immunity cycle. AB - The imbalance of immune status in cancer microenvironment plays an important role in the development and progression of cancer. Immunotherapy based on this has become an important field of cancer research in recent years. Many studies on long noncoding RNA (lncRNA) in cancer have focus on its regulation in cancer development and metastasis. Recent studies have suggested that lncRNAs play crucial roles in different phases of cancer immunity, including antigen releasing, antigen presentation, immune activation, immune cells migration, infiltrating into cancer tissues, and killing cancer cells. The functional studies of lncRNAs in cancer immuntity revealed the complicated molecular mechanisms in cancer immunity from a new point of view, which may provide novel potential targets for cancer immunotherapies. Based on the classical cancer immunity cycle theory, we review the recent studies on the functions and mechanisms of immune-related lncRNAs in different stages of cancer immunity, to summarize the relationship between lncRNAs, and cancer immunity and to provide a framework for further research. PMID- 29574912 TI - Evaluation of the fetal palate at 11 to 13 (+6) weeks of gestation based on an analysis of static ultrasound images using modern IT techniques. AB - OBJECTIVE: To describe a new computer-based technique to isolate the shape of the fetal palate visible in the midsagittal plane from static ultrasound images routinely used to measure nuchal translucency. METHOD: This is a retrospective interpretation of images of the midsagittal view of the fetal face at 11 to 13 (+6) weeks of gestation in 7 cases of cleft lip and palate (CLP) and 7 normal controls. The images were subjected to pattern analysis. RESULTS: Proprietary software was applied and for each CLP case, and palatine bones with different forms from those of fetuses in the control group were recorded. In 4 cases, an image of a continuous palatine bone was observed at a threshold of 180, whereas the remaining 3 images were obtained at 128. A continuous palatine bone structure was not observed in any fetus from the CLP group, even at a level of 128, when the surrounding structures were visible. CONCLUSION: The application of pattern analysis to a 2D frozen image is a new approach for prenatal diagnostics. This technique may be a helpful tool for physicians and could assist in the diagnosis of cleft palate. PMID- 29574913 TI - Shear Wave Elastography to Assess False Vocal Folds in Healthy Adults: A Feasibility Study. AB - OBJECTIVES: The aim of the study was to investigate the feasibility of using ultrasound shear wave elastography to quantify mechanical properties and movement symmetry of false vocal folds positioned in adduction and abduction. METHODS: We prospectively measured the shear wave velocity (SWV) within the bilateral false vocal folds in 10 healthy adults using acoustic radiation force impulse imaging. From a transcutaneous approach at the level of thyroid cartilage, 5 SWV measurements were obtained within each side of the false vocal folds twice in adduction and again in abduction for each participant. Configuration-related differences in the SWV within false vocal folds were compared between adduction and abduction, in addition to differences between the right and left false vocal folds and between men and women, by a paired t test. We developed an SWV index [(SWVgreater - SWVlesser )/SWVgreater ] to assess movement symmetry between the right and left false vocal folds. Intraobserver agreement on repeated measures was examined by the intraclass correlation coefficient. RESULTS: The 10 participants included 5 men and 5 women. We observed that the SWV within false vocal folds was significantly higher in adduction than in abduction (P < .001). The SWV within false vocal folds in adduction was also significantly higher in women compared to men (P < .001). There was no significant difference in the SWV between the right and left false vocal folds in adduction or in abduction or between men and women in abduction (P > .05). The mean SWV index was 0.05 (range, 0.03-0.07). The intraclass correlation coefficient for intraobserver agreement was 0.89 (P < .001). CONCLUSIONS: Shear wave elastography seems to be feasible to quantify mechanical properties and evaluate the symmetry of false vocal folds in healthy adults.

AB - Allogeneic hematopoietic cell transplantation (alloHCT) with myeloablative conditioning based on total body irradiation (TBI) is widely used for the treatment of adults with acute lymphoblastic leukemia (ALL). TBI is most frequently administered in combination with either cyclophosphamide (Cy/TBI) or etoposide (Vp/TBI). The goal of this study was to retrospectively compare these two regimens. Adult patients with Ph-negative ALL treated with alloHCT in first or second complete remission who received Cy/TBI (n = 1346) or Vp/TBI (n = 152) conditioning were included in the analysis. In a univariate analysis, as compared to Cy/TBI, the use of Vp/TBI was associated with reduced incidence of relapse (17% vs. 30% at 5 years, P = .007), increased rate of leukemia-free survival (60% vs. 50%, P = .04), and improved "graft versus host disease (GVHD) and relapse free survival" (GRFS, 43% vs. 33%, P = .04). No significant effect could be observed in terms of the incidence of nonrelapse mortality or acute or chronic GVHD. In a multivariate model, the use of Vp/TBI was associated with reduced risk of relapse (HR = 0.62, P = .04) while the effect on other study end-points was not significant. In conclusion, conditioning regimen based on Vp combined with TBI appears more effective for disease control than the combination of Cy with TBI for adult patients with Ph-negative ALL treated with alloHCT. PMID- 29574916 TI - Determinants of change in home participation among critically ill children. AB - AIM: To estimate changes in home participation among critically ill children in the first 6 months after discharge from a pediatric intensive care unit (PICU), and to explore the effect of child, service, and environmental factors on change in home participation. METHOD: This was a prospective bi-center, longitudinal cohort study. Caregivers of 180 children, aged 1 to 17 years, who were admitted into the PICU for at least 48 hours were included. Patient-reported outcomes were used to capture caregivers' perspectives of their child's participation and environmental supports for participation in home activities. Data were collected at enrollment, and 3 and 6 months after discharge. RESULTS: There were no significant changes in home participation frequency or involvement, but involvement rates across time were moderated by functional status. Age significantly predicted participation frequency. Pre-PICU functional status and capabilities were significant predictors of participation frequency and involvement, and home environmental support significantly predicted home involvement. INTERPRETATION: Results suggest relatively stable participation trajectories in the 6 months after PICU admission. Children with abnormal baseline function experienced a greater increase in home involvement after PICU. Rehabilitation interventions targeting functional capabilities and home environment may be viable approaches during the early phase of recovery. Environmental interventions may be more time-efficient after PICU stay and merit further study. WHAT THIS PAPER ADDS: Children's pre-pediatric intensive care unit (PICU) functional status and capabilities impact their participation after critical illness. Children's trajectories of home involvement may differ over time based on their pre-PICU functional status. Caregiver perceptions of environmental support impact a child's home involvement after discharge from a PICU. PMID- 29574917 TI - The tracheal system in post-embryonic development of holometabolous insects: a case study using the mealworm beetle. AB - The tracheal (respiratory) system is regarded as one of the key elements which enabled insects to conquer terrestrial habitats and, as a result, achieve extreme species diversity. Despite this fact, anatomical data concerning this biological system is relatively scarce, especially in an ontogenetic context. The purpose of this study is to provide novel and reliable information on the post-embryonic development of the tracheal system of holometabolous insects using micro-computed tomography methods. Data concerning the structure of the respiratory system acquired from different developmental stages (larvae, pupae and adults) of a single insect species (Tenebrio molitor) are co-analysed in detail. Anatomy of the tracheal system is presented. Sample sizes used (29 individuals) enabled statistical analysis of the results obtained. The following aspects have been investigated (among others): the spiracle arrangement, the number of tracheal ramifications originating from particular spiracles, the diameter of longitudinal trunks, tracheal system volumes, tracheae diameter distribution and fractal dimension analysis. Based on the data acquired, the modularity of the tracheal system is postulated. Using anatomical and functional factors, the following respiratory module types have been distinguished: cephalo-prothoracic, metathoracic and abdominal. These modules can be unambiguously identified in all of the studied developmental stages. A cephalo-prothoracic module aerates organs located in the head capsule, prothorax and additionally prolegs. It is characterised by relatively thick longitudinal trunks and originates in the first thoracic spiracle pair. Thoracic modules support the flight muscles, wings, elytra, meso- and metalegs. The unique feature of this module is the presence of additional longitudinal connections between the neighbouring spiracles. These modules are concentrated around the second prothoracic and the first abdominal spiracle pairs. An abdominal module is characterised by relatively thin ventral longitudinal trunks. Its main role is to support systems located in the abdomen; however, its long visceral tracheae aerate organs situated medially from the flight muscles. Analysis of changes of the tracheal system volume enabled the calculation of growth scaling among body tissues and the volume of the tracheal system. The data presented show that the development of the body volume and tracheal system is not linear in holometabola due to the occurrence of the pupal stage causing a decrease in body volume in the imago and at the same time influencing high growth rates of the tracheal system during metamorphosis, exceeding that ones observed for hemimetabola. PMID- 29574918 TI - Ginsenoside Rb1 inhibits autophagy through regulation of Rho/ROCK and PI3K/mTOR pathways in a pressure-overload heart failure rat model. AB - OBJECTIVE: This study was designed to explore the relationship between ginsenoside Rb1 (Grb1) and high-load heart failure (HF) in rats. METHODS: The parameters of cardiac systolic function (left ventricular posterior wall thickness (LVPWT), left ventricular internal diastolic diameter (LVID), fraction shortening (FS) and mitral valves (MVs)) of rat hearts in each group were inspected by echocardiogram. The expressions of rat myocardial contractile proteins, autophagy-related proteins and the activation of Rho/ROCK and PI3K/mTOR pathways were detected by Western blot. KEY FINDINGS: LVPWT, FS, MVs and the expression of myocardial contractile proteins alpha-MHC, apoptosis-related proteins Bcl-2 and signalling pathway involved proteins pAkt and mTOR were significantly reduced in the HF, HF+5 mg/kg Grb1 (HF+Grb1-5) and HF+Grb1+arachidonic acid (AA) groups with LVID, beta-MHC, cell apoptosis, cell autophagy and Rho/ROCK significantly increased compared with the control group, of which the tendency was contrary to the HF+20 mg/kg Grb1 (HF+Grb1-20) group compared with the HF group (P < 0.05). In the HF+Grb1+AA group, there was no significant change in the above indexes compared with the HF group. CONCLUSIONS: The results indicated that Grb1 can exert anti-HF function by inhibiting cardiomyocyte autophagy of rats through regulation of Rho/ROCK and PI3K/mTOR pathways.

Why is there environmental variation for genetic effects? 33 IV. Conclusions 35 Acknowledgements 35 References 35 SUMMARY: Phenotypic plasticity is common in nature, yet we lack a comprehensive understanding of the evolutionary forces that shape genetic variation for plasticity. This endeavor is especially important because variation for plasticity will result in genotype-by environment interactions (G * E), a crucial component of variation in quantitative traits. Here, I review our understanding of the evolutionary forces shaping G * E, focusing specifically on: what evolutionary forces maintain variation for plasticity; and what forces maintain different genetic architectures across environments. My specific goal is to show that genomic data can be leveraged to explain the maintenance of G * E by contrasting patterns of genetic variation for plasticity with neutral expectations. PMID- 29574920 TI - Transcutaneous electrical stimulation on the anterior neck region: The impact of pulse duration and frequency on maximum amplitude tolerance and perceived discomfort. AB - Maximum amplitude tolerance (MAT) has been known as a primary factor determining the depth of electrical current penetration. However, the effect of varying transcutaneous electrical stimulation (TES) parameters on MAT and discomfort level is poorly understood. Furthermore, limited information exists regarding the biopsychological factors that may impact MAT and discomfort. The primary aims of this study were to compare the effects TES protocol with varying levels of pulse duration (300 MUs vs 700 MUs) and frequency (30 Hz vs 80 Hz) on the MAT and discomfort in healthy older adults. The exploratory aim of this study was to examine relationships between submental adipose tissue thickness, pain sensitivity and gender with MAT and discomfort. Twenty-four healthy older adults participated in this study. Transcutaneous electrical stimulation was delivered to the submental region. Maximum amplitude tolerance and discomfort were measured for each condition. Furthermore, submental adipose tissue thickness and pain sensitivity were measured for each subject. Maximum amplitude tolerance was significantly increased for the TES protocols with short-pulse duration [F (3, 69) = 38.695, P < .0001]. Discomfort was similar across different TES protocols. Submental adipose tissue thickness (r = .30, P < .003) and pain sensitivity (r = .43, P < .0001) were related to MAT. Pain sensitivity rating was also related to discomfort (r = .45, P < .0001). In conclusion, using TES protocols with short pulse duration may increase the MAT. Higher amplitude stimulation may increase the impact on deep swallowing muscles. In addition, submental adipose tissue thickness and pain sensitivity are potential biopsychological factors that may affect MAT and discomfort. PMID- 29574921 TI - Naturally occurring antiviral drug resistance in HIV patients who are mono infected or co-infected with HBV or HCV in China. AB - Drug resistance mutations (DRMs) may reduce the efficacy of antiviral therapy. However, the studies focused on naturally occurring, pre-existing DRMs among co infected patients in China are limited. To investigate DRMs prevalence in treatment-naive human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) mono- and co-infected patients in China, a total of 570 patients were recruited for this study. DRMs sequences were amplified and successfully sequenced in 481 of these patients, who were grouped into three cohorts: (i) The HBV cohort included 100 HIV/HBV co-infected and 110 HBV mono infected patients who were sequenced for HBV; (ii) The HCV cohort included 91 patients who were HIV/HCV co-infected and 72 who were HCV mono-infected for HCV sequencing; and (iii) The HIV cohort included 39 HIV mono-infected, 22 HIV/HCV, and 47 HIV/HBV co-infected patients for HIV sequencing. Next-generation sequencing and Sanger sequencing were used in this study. The results showed that in the HCV cohort, HCV genotypes 6a (P < 0.001) and 3b (P = 0.004) were more prevalent in HIV/HCV co-infected patients, however, the prevalence of HBV and HIV genotypes were similar within the HBV and HIV cohorts. HBV DRMs prevalence was significantly higher in HIV/HBV co-infected than HBV mono-infected patients (8.0% vs 0.9%, P = 0.015), whereas HCV and HIV DRMs did not differ within the HCV and HIV cohort (P > 0.05). This study revealed that HBV DRMs were more prevalent in HIV/HBV co-infected patients in China, while DRMs in HCV and HIV patients did not differ. Further dynamic surveillance of DRMs may be needed. PMID- 29574923 TI - DNA methylation level of spermatozoa from subfertile and proven fertile and its relation to standard sperm parameters. AB - The epigenetic mechanism plays an important role in spermatogenesis such as DNA methylation where this episode is represented by either switching genes on or off. Twenty-eight samples (14 case and 14 controls) were subjected to Infinium 450K BeadChip arrays to identify genomic regions that differ in sperm DNA methylation patterns in the subfertile compared to the proven fertile group. Then two CpGs were validated by deep bisulphite sequencing on 82 sperm samples. The results screening study revealed eight CpGs were significantly different in their sperm DNA methylation levels between cases and control group. The results of the validation study for the two CpGs (cg19779893 and cg19406113) showed that a significant variation in the methylation level at 2 CpGs of 3 CpGs related to cg19779893 site amplicon in cases compared to the controls. Moreover, six CpGs related to the cg19406113 site amplicon showed significant differences in sperm DNA methylation between the cases and the control group. Furthermore, there was a significant decrease in the sperm parameters in the cases compared to the control group. This study found two CpGs altered in their sperm DNA methylation levels. In addition, a strong association was found between changes in the sperm DNA methylation levels in these CpGs sites and sperm parameters. PMID- 29574922 TI - Transitioning patients with immune thrombocytopenia to second-line therapy: Challenges and best practices. AB - In patients with immune thrombocytopenia who do not adequately respond to first line therapy, there is no clear consensus on which second-line therapy to initiate and when. This situation leads to suboptimal approaches, including prolonged exposure to treatments that are not intended for long-term use (eg, corticosteroids) and overuse of off-label therapies (eg, rituximab) while approved, more efficacious options exist. These approaches may not only fail to address symptoms and burden of disease, but may also worsen health-related quality of life. A better understanding of available second-line treatments may ensure best use of therapeutic options and thereby optimize patient outcomes. PMID- 29574924 TI - The effects of transient receptor potential channel (TRPC) on airway smooth muscle cell isolated from asthma model mice. AB - This study aimed to validate whether transient receptor potential channel1 (TRPC1) and TRPC3 participate in the regulation the proliferation of airway smooth muscle cells (ASMCs) through modulating calcium ion (Ca2+ ) influx in vitro. Chronic model of murine asthma was induced and ASMCs isolated from asthmatic mice were used in this whole study. TRPC1 and TRPC3 were upregulated in asthmatic mouse ASMCs and selected for further investigation. Ca2+ concentration and the cell viability of asthmatic mouse ASMCs were significantly higher than that from non- asthma mice, however, TRPC channels blocker SKF96365 alleviated these effects. Furthermore, TRPC1 or TRPC3 overexpression markedly increased Ca2+ concentration and significantly induced the viability of ASMCs; whereas TRPC1 or TRPC3 knockdown exerted the completely conversed effects. Moreover, knockdown of TRPC1 and TRPC3 also exerted different effects on the protein expression of growth-related proteins p-p38, p-JNK, cleaved caspase-3 and Bcl-2, as well as on cell cycle. Finally, we found Ca2+ chelator EGTA or BAPTA-AM significantly diminished the effects of si-TRPC1 and si-TRPC3 on the cell viability, cell cycle, and the protein expression of p-p38, p-JNK, cleaved caspase-3, and Bcl-2 in asthmatic mouse ASMCs. Our findings demonstrated that the effects of TRPC1 and TRPC3 on the cell viability and cell cycle of ASMCs were, at least partially, through regulating Ca2+ influx.

PMID- 29574925 TI - Low-density lipoprotein-cholesterol lowering in individuals at intermediate cardiovascular risk: Percent reduction or target level? AB - BACKGROUND: Recommendations for blood cholesterol management differ across different guidelines. HYPOTHESIS: Lipid-lowering strategies based on low-density lipoprotein-cholesterol (LDL-c) percent reduction or target concentration may have different effects on the expected cardiovascular benefit in intermediate risk individuals. METHODS: We selected individuals between 40 and 75 years of age with 10-year risk for atherosclerotic cardiovascular disease (ASCVD) between 5.0% and <7.5% who underwent a routine health screening. For every subject, we simulated a strategy based on a 40% LDL-c reduction (S40% ) and another strategy based on achieving LDL-c target <=100 mg/dL (Starget-100 ). The cardiovascular benefit was estimated assuming a 22% relative risk reduction in major cardiovascular events for each 39 mg/dL of LDL-c lowered. RESULTS: The study comprised 1756 individuals (94% men, 52 +/- 5 years old). LDL-c and predicted 10 year ASCVD risk would be slightly lower in S40% compared to Starget-100 . The number needed to treat to prevent 1 major cardiovascular event in 10 years (NNT10 ) would be 56 with S40% and 66 with Starget-100 . S40% would prevent more events in individuals with lower baseline LDL-c, whereas Starget-100 would be more protective in those with higher LDL-c. A dual-target strategy (40% minimum LDL-c reduction and achievement of LDL-c <=100 mg/dL) would be associated with outcomes similar to those expected with the S40% (NNT10 = 55). CONCLUSIONS: In an intermediate-risk population, cardiovascular benefit from LDL-c lowering may be optimized by tailoring the treatment according to the baseline LDL-c or by setting a dual-target strategy (fixed dose statin plus achievement of target LDL c concentration). PMID- 29574927 TI - Parental posttraumatic stress and child behavioral problems in world trade center responders. AB - BACKGROUND: We investigated trans-generational associations between Post Traumatic Stress Disorder (PTSD) symptoms in World Trade Center (WTC) responders and behavioral problems in their children. METHODS: Participants were WTC responders-8034 police and 8352 non-traditional (eg, construction workers)-with one or more children at the time of their first visit to the World Trade Center Health Program (WTC-HP). Self-report questionnaires were administered approximately 4 years after the 9/11 WTC attack. RESULTS: A total of 31.4% of non traditional and 20.0% of police responders reported behavioral problems in their children. Non-traditional responder status, female sex, Hispanic ethnicity, more life stressors, more WTC-related PTSD symptoms, and dysphoric arousal symptoms were significant correlates of behavioral problems in responders' children. CONCLUSIONS: Specific parental sociodemographic, psychosocial and clinical characteristics, as well as PTSD symptom severity, were significant correlates of child behavior problems. Findings encourage monitoring and early intervention for children of disaster responders, particularly those at highest risk. PMID- 29574928 TI - Cell type-dependent functions of microRNA-92a. AB - The role of miR-17/92 family in development and progression of various cancers has been established. The members of this miRNA family have been shown to be over expressed and target various genes within proliferation, metastasis and angiogenesis pathways. Although all members might be overexpressed in a certain cancer type, only certain members of the family may have roles in progression of that cancer. In this study, we have chosen miR-92a, a member of the miR-17/92 family to compare its function in three different cancer cell lines. HL60, MCF7, and Jurkat cell lines were transduced with miR-92a and proliferation and apoptosis was measured in these cells by cell count, MTT, and caspase assays. Although in comparison to pre-miR-17/92, the level of miR-92a is higher in Jurkat cells compared to MCF7 and HL60 cells, here we have shown that increasing miR-92a levels results in apoptosis in Jurkat cells and proliferation in MCF7 and HL60 cells. miR-92a was also microinjected into mice fertilized eggs and after dissection, apoptosis was only observed in white pulp of spleen that is mainly made up of white blood cells. Our results show that miR-92a possesses a cell-type dependent function. PMID- 29574929 TI - Impact of histological subtype on the prognosis of patients undergoing surgery for colon cancer. AB - BACKGROUND: The effect of the histological subtype on the prognosis of patients undergoing surgery for colon cancer (CC) is not completely understood. METHODS: The Surveillance, Epidemiology, and End Results (SEER) 2004-2014 database was used to compare the long-term outcomes of patients undergoing colon resection for classical adenocarcinoma (CA), mucinous adenocarcinoma (MUC), and signet-cell adenocarcinoma (SC). RESULTS: A total of 153 317 (89%) patients had CA, 16 660 (10%) MUC while 1810 (1%) patients had SC subtype. Patients with MUC and SC more frequently had a poorly differentiated CC and were more likely to present with advanced disease compared with CA patients (P < 0.001). Patients with CA had a 5 year OS of 62% versus 55% and 34% for patients with MUC and SC subtypes, respectively (P = 0.001). On multivariable analysis, site of cancer, tumor grade, and TNM stage were associated with prognosis (all P < 0.001). After controlling for these risk factors, patients with MUC (HR, 1.09, P < 0.001) and SC (HR, 1.47, P < 0.001) had a roughly 10% and 50% increased hazard of death, respectively, compared with CA patients. CONCLUSIONS: MUC and SC are distinct subtypes of CC associated with a worse prognosis. These data can help inform discussion about prognosis and possibly direct adjuvant management.

We describe the gross and microscopic features of multicentric cutaneous keratoacanthomas in a free-living marmoset (Callithrix sp.). Immunohistochemistry for human papillomavirus and herpes simplex virus type I and simplex virus type II was negative. Keratoacanthomas should be included in the differential diagnosis for cutaneous masses in non-human primates. PMID- 29574931 TI - An Emerging Group of Membrane Property Sensors Controls the Physical State of Organellar Membranes to Maintain Their Identity. AB - The biological membranes of eukaryotic cells harbor sensitive surveillance systems to establish, sense, and maintain characteristic physicochemical properties that ultimately define organelle identity. They are fundamentally important for membrane homeostasis and play active roles in cellular signaling, protein sorting, and the formation of vesicular carriers. Here, we compare the molecular mechanisms of Mga2 and Ire1, two sensors involved in the regulation of fatty acid desaturation and the response to unfolded proteins and lipid bilayer stress in order to identify their commonalities and specializations. We will speculate on the cellular significance of membrane property sensors in other organelles and discuss their putative mechanisms. Based on these findings, we propose membrane property sensors as an emerging class of proteins with wide implications for organelle communication and function. PMID- 29574932 TI - High-Frame Rate Vector Flow Imaging of the Carotid Bifurcation in Healthy Adults: Comparison With Color Doppler Imaging. AB - OBJECTIVES: To evaluate the carotid bifurcation in healthy adults using a commercial system equipped with high-frame rate vector flow imaging (VFI) based on the plane wave and to compare VFI with color Doppler imaging. METHODS: Carotid bifurcation diameters and flow characteristics of 60 vessels in 60 healthy volunteers were evaluated quantitatively and qualitatively to assess complex flow patterns and their extension and duration. RESULTS: Complex flow in the internal carotid artery (ICA) was associated with a statistically significant difference in the DeltaICA sinus-to-common carotid artery (CCA) diameter ratio (the relative change in diameter between the CCA and ICA sinus.) Vector flow imaging and color Doppler imaging were in accordance when detecting complex flow in 96.7% of cases; in 3.3% of cases, only VFI identified small recirculation areas of short duration. Vector flow imaging highlighted a larger extension of the complex flow (mean +/- SD, 47.7 +/- 28.5 mm2 ; median, 45.5 mm2 ) compared with color Doppler imaging (mean, 29.2 +/- 19.9 mm2 ; median, 29.5 mm2 ) and better depicted different complex flow patterns; a strong correlation (r = 0.84) was found between the DeltaICA sinus-to-CCA diameter ratio and the complex flow extension. Vector flow imaging showed a longer duration of the flow disturbances (mean, 380 +/- 218 milliseconds; median, 352.5 milliseconds) compared with color Doppler imaging (mean, 325 +/- 206 milliseconds; median, 333 milliseconds), and there was a strong correlation (r = 0.92). CONCLUSIONS: Vector flow imaging is as effective as color Doppler imaging in the detection of flow disturbances, but it is more powerful in the assessment of complex flow patterns. PMID- 29574933 TI - The association of serum FGF23 and non-alcoholic fatty liver disease is independent of vitamin D in type 2 diabetes patients. AB - Recent studies have shown that circulating fibroblast growth factor (FGF) 23 and vitamin D levels are closely correlated with insulin resistance. The aim of this study was to investigate the relationship among serum FGF 23 levels, serum 25 hydroxyvitamin D [25(OH)D] levels, and non-alcoholic fatty liver disease (NAFLD) in Chinese patients with type 2 diabetes mellitus (T2DM). This study enrolled 331 hospitalized T2DM patients (209 patients with NAFLD and 122 patients without NAFLD). Serum FGF23 levels were measured using a sandwich enzyme-linked immunosorbent assay. Serum 25(OH)D levels were determined by an electrochemiluminescence immunoassay. NAFLD was diagnosed by hepatic ultrasound, and the fatty liver index (FLI) was calculated to quantify hepatic steatosis. Results showed that T2DM patients with NAFLD had significantly higher serum FGF23 levels (44.17 [37.92-51.30] pg/mL vs 40.21 [34.07-48.33] pg/mL, P = .002), but lower serum 25(OH)D levels (16.43 [12.70-21.37] ng/mL vs 19.59 [13.78-26.26] ng/mL, P = .002) than those without NAFLD. Moreover, the incidence rate of NAFLD increased with increasing serum FGF23 levels and decreased with increasing 25(OH)D levels (both P < .05). Logistic regression analysis showed that both serum FGF23 and 25(OH)D levels were independent factors for NAFLD (both P < .05). Furthermore, a multiple stepwise regression analysis also revealed that both serum FGF23 and 25(OH)D levels were independently correlated with FLI (both P < .01). In conclusion, both high FGF23 and low vitamin D levels showed an independent relationship with NAFLD in Chinese T2DM patients, indicating that FGF23 and vitamin D function via different regulatory pathways in the liver.

PMID- 29574934 TI - The power of precise bioinformatics prediction of miRNA:mRNA interactions:miR 4699 as a potential inducer of Wnt signaling pathway. AB - microRNAs have attracted interest because of their regulatory effects on gene expression. Experimental detection of potential targets of miRNAs is a laborious task. Considering the expensive techniques of detection, computational approaches for miRNA target prediction can be used as the first step in miRNA research. A large number of tools and algorithms have been developed during the last two decades, led to problems such as confusion in selecting an appropriate tool and false positive or negative results. Therefore, one of the most frequent problems and critical issues of miRNA research is finding a reliable miRNA target prediction tool. In this study, we have proposed a research direction and introduced user-friendly and current databases and tools with the highest accuracy. To verify whether our proposed research direction is practical, we have provided a case example of predicting a miRNA which can target negative regulators of osteogenesis and experimentally evaluated the accuracy of the prediction results by Real-Time PCR and Luciferase assay. The results of RT-qPCR and Luciferase assay indicated a significant decline in expression of Dickkopf related protein 1 (DKK1) and tumor necrosis factor ligand superfamily member 11 (TNFSF11) as the key negative regulators of osteogenesis upon overexpression of miR-4699-3p. The results emphasize the validity and importance of accurate in silico investigation as the first step in experimental studies. This is the first report detailing the prediction and validation of miR-4699-3p target genes. We suggest hsa-miR-4699 for further investigation as an osteogenic miRNA for therapeutics purposes. PMID- 29574936 TI - Analysis of tumoral spheres growing in a multichamber microfluidic device. AB - Lab on a Chip (LOC) farming systems have emerged as a powerful tool for single cell studies combined with a non-adherent cell culture substrate and single cell capture chips for the study of single cell derived tumor spheres. Cancer is characterized by its cellular heterogeneity where only a small population of cancer stem cells (CSCs) are responsible for tumor metastases and recurrences. Thus, the in vitro strategy to the formation of a single cell-derived sphere is an attractive alternative to identify CSCs. In this study, we test the effectiveness of microdevices for analysis of heterogeneity within CSC populations and its interaction with different components of the extracellular matrix. CSC could be identify using specific markers related to its pluripotency and self-renewal characteristics such as the transcription factor Oct-4 or the surface protein CD44. The results confirm the usefulness of LOC as an effective method for quantification of CSC, through the formation of spheres under conditions of low adhesion or growing on components of the extracellular matrix. The device used is also a good alternative for evaluating the individual growth of each sphere and further identification of these CSC markers by immunofluorescence. In conclusion, LOC devices have not only the already known advantages, but they are also a promising tool since they use small amounts of reagents and are under specific culture parameters. LOC devices could be considered as a novel technology to be used as a complement or replacement of traditional studies on culture plates. PMID- 29574937 TI - Serologic markers of viral infection and risk of non-Hodgkin lymphoma: A pooled study of three prospective cohorts in China and Singapore. AB - Incidence rates of non-Hodgkin lymphoma (NHL) and distributions of certain viruses differ between East Asian and Western populations. There are limited data on associations between serologic markers of multiple viral infections in pre diagnostic blood and NHL risk in East Asians. We conducted a nested case-control study of 214 NHL cases and 214 matched controls from three population-based prospective cohorts in Shanghai and Singapore. Antibodies against antigens from herpesviruses, Hepatitis B (HBV) and C (HCV) virus and polyomaviruses were measured in plasma or serum using fluorescent bead-based multiplex assays. Conditional logistic regression was used to evaluate associations between antibody levels and NHL risk. An increased risk of NHL was observed for higher compared to lower EA-D (Odds Ratio (OR) = 2.04, 95% Confidence Interval (CI) = 1.10-3.81; ptrend = 0.005) and ZEBRA (OR = 2.17, 95% CI = 0.96-4.89; ptrend = 0.008) Epstein-Barr Virus (EBV) antibodies, as well as for antibody seropositivity against the IE1A human herpesvirus-6 (HHV-6) antigen (OR = 1.85, 95% CI = 1.04-3.29). An increased NHL risk was also observed for higher compared to lower antibodies against the HBV-HBc and HBe antigens. An increased risk of NHL in relation to EBV and HBV infection in East Asians is consistent with findings in several studies of Western populations, suggesting similar viral risk factors for NHL in these diverse populations with distinct patterns of NHL. The association between HHV-6 antibodies and NHL has not previously been reported in a prospective study in this population and will require replication. PMID- 29574938 TI - Resolvin E1 (Rv E1 ) attenuates LPS induced inflammation and subsequent atrophy in C2C12 myotubes. AB - Resolution of inflammation is now known to be an active process which in part is instigated and controlled by specialized pro-resolving lipid mediators (SPM's) derived from dietary omega-3 fatty acids. Resolvin E1 (Rv E1 ) is one of these SPM's derived from the omega-3 fatty acid eicosapentaenoic acid. Using both molecular and phenotypic functional measures we report that in a model of Lipopolysaccharide (LPS) induced inflammation, Rv E1 attenuated mRNA levels of both interlukin-6 and monocyte chemoattractant protein-1 whilst having no effect on tumor necrosis factor-alpha or interlukin-1beta in C2C12 skeletal muscle myotubes. Findings at the molecular level were transferred into similar changes in extracellular protein levels of the corresponding genes with the greatest attenuation being noted in IL-6 protein concentrations. Rv E1 instigated beneficial morphological changes through the prevention of LPS induced skeletal muscle atrophy, in tandem with attenuation of the LPS induced reduction in contractile force in tissue engineered skeletal muscle. These findings demonstrate, in our model of endotoxin induced inflammation in skeletal muscle, that Rv E1 has pro-resolving properties in this cell type. Our data provides rationale for further investigation into the mechanistic action of Rv E1 in skeletal muscle, with the vision of having potential benefits for the prevention/resolution of in-vivo skeletal muscle atrophy. PMID- 29574939 TI - Reconstruction of undersampled radial free-breathing 3D abdominal MRI using stacked convolutional auto-encoders. AB - PURPOSE: Free-breathing three-dimensional (3D) abdominal imaging is a challenging task for MRI, as respiratory motion severely degrades image quality. One of the most promising self-navigation techniques is the 3D golden-angle radial stack-of stars (SOS) sequence, which has advantages in terms of speed, resolution, and allowing free breathing. However, streaking artifacts are still clearly observed in reconstructed images when undersampling is applied. This work presents a novel reconstruction approach based on a stacked convolutional auto-encoder (SCAE) network to solve this problem. METHODS: Thirty healthy volunteers participated in our experiment. To build the dataset, reference and artifact-affected images were reconstructed using 451 golden-angle spokes and the first 20, 40, or 90 golden angle spokes corresponding to acceleration rates of 31.4, 15.7, and 6.98, respectively. In the training step, we trained the SCAE by feeding it with patches from artifact-affected images. The SCAE outputs patches in the corresponding reference images. In the testing step, we applied the trained SCAE to map each input artifact-affected patch to the corresponding reference image patch. RESULT: The SCAE-based reconstruction images with acceleration rates of 6.98 and 15.7 show nearly similar quality as the reference images. Additionally, the calculation time is below 1 s. Moreover, the proposed approach preserves important features, such as lesions not presented in the training set. CONCLUSION: The preliminary results demonstrate the feasibility of the proposed SCAE-based strategy for correcting the streaking artifacts of undersampled free breathing 3D abdominal MRI with a negligible reconstruction time.

AB - AIMS: To evaluate the evidence of the effectiveness and safety of Chinese herbal medicine skin-patches for patients with acute gouty arthritis. BACKGROUND: Acute gouty arthritis is a problem that can limit the level of activity and impair the quality of life. In China, many clinical studies have demonstrated that skin patches of Chinese herbal medicines benefit patients with acute gouty arthritis. However, the reported clinical effects vary. DESIGN: A systematic review and meta analysis of randomized controlled trials. DATA SOURCES: Three English databases including CENTRAL (1993 to February 2017), PubMed (1966 to February 2017) and EMBASE (1974 to February 2017) and four Chinese databases including Chinese National Knowledge Infrastructure, Chinese VIP Information, SinoMed and Wanfang (all, 1949 - February 2017) were searched. Randomized controlled trials that compared skin-patches of Chinese herbal medicine with or without conventional treatments to conventional treatments, no treatment or a placebo treatment for patients with acute gouty arthritis were included. REVIEW METHODS: We conducted a systematic review and meta-analysis following the Cochrane process. Two authors selected the studies, extracted the data and evaluated the risk of bias of the included trials. RESULTS: Nineteen studies met our inclusion criteria. After synthesizing the data, the results showed that skin-patches of CHM combined with Western medicine seemed to be more effective than Western medicine alone for pain relief in patients with acute gouty arthritis and had fewer adverse events. CONCLUSION: Due to the quality of the data, larger and more rigorously designed clinical trials with proper outcome measures are necessary. PMID- 29574942 TI - The contribution of occupation to children's experience of resilience: A qualitative descriptive study. AB - BACKGROUND: This qualitative descriptive study explored what occupations children aged 10-13 years participate in and how participation in occupation contributes to resilience from their perspective. Little is known about how occupations contribute to resilience, and less is known from children's perspectives. Exploring how participation in occupation contributes to resilience is important as children continue to face adverse situations; resilience may help protect their development against uncertainty. METHODS: Following ethics approval eight participants were recruited through schools in a large New Zealand city. Data were collected through semi-structured interviews and one focus group, these were audio recorded and transcribed. The six-phase process of thematic analysis, developed by Braun and Clarke (), was utilised to analyse the data. FINDINGS: Three main themes emerged from the data: what resilience is, occupations children do and how those occupations contribute to resilience and thirdly; building participation and resilience. The study revealed sophisticated descriptions of what resilience meant to the participants from their experience, which included the ideas of bouncing back and staying strong. The participants described what occupations they participate in and how these occupations connect to resilience. The participants also described their experience of how participation in their occupations helped build resilience by fostering support, letting go, experiencing distraction, and experiencing fun and happiness. CONCLUSION: The findings suggest that health professionals, policy makers and educators have much to learn from children. Specifically, the need for children to participate in occupations as a way to build resilience. This indicates that a child-focussed approach is needed to incorporate children's perspectives in practice and policy development. The findings suggest that practitioners working with children should incorporate participation in occupation in social, health and education intervention plans with children, as well as use occupation based coping strategies when teaching children skills to manage challenges in life.

AB - People commonly use the Internet to search for health information and tend to use the information they find without regard to source or credibility. Although regulation plays some role in minimizing false claims made by manufacturers of self-help products, effective communication with health professionals likely offers greater protection to the patient or consumer accessing self-help materials. In order to best serve patients (or healthcare consumers), providers should educate them about their healthcare needs, inquire about self-help product use, understand appropriate use, discuss the risks and benefits of use, monitor the patients' condition during use, and document these conversations. Although some people fear that patient use of brain-themed self-help will undermine the doctor-patient relationship, it is more likely to open another avenue of communication if providers are knowledgeable about self-help products. Given the rise in importance of the Internet as a source of information for people, opting out of these discussions is realistically not an option. PMID- 29574945 TI - Exogenous Cushing syndrome from an unexpected source of systemic steroids. AB - A 12-year-old Hispanic boy with chronic atopic dermatitis and cushingoid features presented to our institution. He was being treated with an unknown quantity of oral prednisolone 15 mg/5 mL, equivalent to 70 mg/m2 /d of oral prednisone, purchased over the counter in El Salvador. Systemic corticosteroids are not recommended for chronic therapy of atopic dermatitis because of their significant adverse effects. Foreign-sourced pharmaceuticals account for almost half of the drugs consumed in the United States, which means that, to protect our patients, medical providers must inquire about and report unsafe medications deemed legal outside the United States to the Food and Drug Administration. PMID- 29574946 TI - Cyclic AMP and glycogen synthase kinase 3 form a regulatory loop in spermatozoa. AB - The multifaceted glycogen synthase kinase (GSK3) has an essential role in sperm and male fertility. Since cyclic AMP (cAMP) plays an important role in sperm function, we investigated whether GSK3 and cAMP pathways may be interrelated. We used GSK3 and soluble adenylyl cyclase (sAC) knockout mice and pharmacological modulators to examine this relationship. Intracellular cAMP levels were found to be significantly lower in sperm lacking GSK3alpha or GSK3beta. A similar outcome was observed when sperm cells were treated with SB216763, a GSK3 inhibitor. This reduction of cAMP levels was not due to an effect on sperm adenylyl cyclase but was caused by elevated phosphodiesterase (PDE) activity. The PDE4 inhibitor RS25344 or the general PDE inhibitor IBMX could restore cAMP levels in sperm lacking GSK3alpha or beta-isoform. PDE activity assay also showed that hyperactivated PDE4 contributes in lowering of cAMP levels in GSK3alpha null sperm suggesting that in wild-type sperm PDE4 activity is kept in check by GSK3. Conversely, PKA being triggered by cAMP, affected GSK3 activity through increasing its phosphorylation. Increased GSK3 phosphorylation also occurred by inhibition of sperm specific protein phosphatase type 1, PP1gamma2. The relationship between cAMP, GSK3, and PP1gamma2 activities was also confirmed in sperm from sAC null mice. Pull-down assay using recombinant PP1gamma2 indicated that PKA, GSK3, and PP1gamma2 could exist as a complex. Pharmacological inhibition of GSK3 in mature spermatozoa resulted in significantly reduced fertilization of eggs in vitro. Our results show that cAMP, PKA, and GSK3 are interrelated in regulation of sperm function. PMID- 29574947 TI - Corrigendum. PMID- 29574948 TI - Editorial: Beyond behavior?

PMID- 29574949 TI - Biological effects of interleukin-6 on Gingival Fibroblasts: Cytokine regulation in periodontitis. AB - Periodontitis is a bacterial infectious disease, and many inflammatory cytokines regulate periodontitis pathophysiology through a crosstalk between tissue cells and immune cells. Interleukin (IL)-6 is an important cytokine involved in the regulation of host response to bacterial infection. Human Gingival Fibroblasts (HGFs) are the most abundant cells in gingival connective tissues. Various HGF responses to periodontal pathogens or inflammatory cytokines contribute to the development of periodontitis. Lipopolysaccharide derived from Porphyromonas gingivalis (Pg LPS) and IL-1beta significantly increase IL-6 production in HGFs. However, IL-6 cannot function in HGFs without the soluble form of the IL-6 receptor (sIL-6R), because HGFs do not express sufficient cell surface IL-6R to bind appreciable levels of IL-6. Importantly, sIL-6R is essential for IL-6 signaling in HGFs, and the sIL-6R is produced by differentiated THP-1 cells treated with IL-6. Calprotectin, a heterodimer of S100A8 and S100A9, is released during inflammation and significantly induces IL-6 production in HGFs via toll like receptor 4 (TLR4)/nuclear factor-kappa B (NF-kappaB) signals. Calprotectin also induces sIL-6R production in differentiated THP-1 cells. IL-6 induces vascular endothelial growth factor (VEGF), matrix-metalloproteinase-1 (MMP-1), and cathepsin L production in HGFs in the presence of sIL-6R. Taken together, calprotectin-induced IL-6 production in HGFs may cause periodontitis progression through a crosstalk of fibroblasts and macrophages. There are many reports that examine how cytokines are released from HGFs to cause beneficial or harmful effects in inflamed periodontal lesions. This review explores the pathophysiology of periodontitis by focusing IL-6-mediated crosstalk of HGFs and macrophages. PMID- 29574950 TI - Automated RBC exchange compared to manual exchange transfusion for children with sickle cell disease is cost-effective and reduces iron overload. AB - BACKGROUND: Chronic transfusion in sickle cell disease (SCD) remains the gold standard therapy for stroke prevention and for patients with severe disease despite adequate hydroxyurea treatment. The aim of our study was to assess the safety and efficacy of automated red blood cell exchange (aRBX) in patients with SCD previously treated with manual exchange transfusion (MET). Costs related to transfusion and chelation overtime were evaluated. STUDY DESIGN AND METHODS: Beginning in January 2012, children with SCD who weighed 30 kg or more on MET could switch to aRBX. Clinical, biological, and procedures' data, including costs, were recorded for the last 6 months on MET and compared to those after the first and the second year on aRBX. RESULTS: Ten patients switched from MET to aRBX at a median age of 11.8 years. After the switch, median hemoglobin S (HbS) increased significantly (33.5% on MET compared to 45% on aRBX; p < 0.001) but remained in the target values for all patients. Median ferritin decreased significantly (663.3 ug/L on MET compared to 126.8 ug/L on aRBX; p < 0.001) and intervals between procedures were significantly longer. The requirements of red blood cells (RBCs)/kg/year were not different on MET (0.88 unit/kg/year) than during the second year on aRBX (1.07 unit/kg/year; p = NS). MET costs were similar compared to aRBX since chelation was stopped in previously treated patients. CONCLUSION: Erythrocytapheresis reduces iron overload and allows a longer interval between procedures without a higher RBC requirement from the second year on aRBX. The cost did not increase as estimated in our Belgian Health Care System. PMID- 29574951 TI - In vitro water resistance testing using SPF simulation based on spectroscopic analysis of rinsed sunscreens. AB - OBJECTIVE: Water resistance retention (WRR) is the third performance attribute of sunscreens. Today, the standardized method for testing WRR is performed in vivo. For screening purposes, an in vitro method is highly preferable. Up to now, however, available methods have failed in accurately predicting in vivo WRR. In this study, we examine a novel in vitro approach aimed at enhancing in vivo prediction of WRR. METHODS: We investigated two approaches, including a traditional procedure referred to as the 'plate method', which involves measuring in vitro sun-protection factor (SPF) before and after water immersion, and a new approach termed the 'solution method'. The latter employed a computational method to calculate the SPF using UV transmittance measurements of a sunscreen solution, obtained by rinsing the substrate without water immersion and with water immersion. It also had a model function for describing film irregularity. The aim was to avoid the effect of substrate-to-product affinity on the film distribution, which impacts the measured absolute value of the in vitro SPF occurring in the conventional approach. For both methodologies, we assessed two substrates for the sunscreen application based on different polymers, the widely used polymethylmethacrylate (PMMA) and the ethylene methacrylate acid copolymer (EMA). RESULTS: The agreement between in vivo and in vitro WRR values obtained from each of the four test conditions was analysed using different sunscreens. No correlation was found between in vivo and in vitro WRR using the plate method, independently of the plate type. In contrast, the solution method, using EMA plates, revealed a significant correlation between in vivo and in vitro results, with an especially high correlation for in vivo non-water-resistant sunscreens. The results of two operators were comparable. The solution method was unsuitable for PMMA plates. CONCLUSION: Despite the small discrepancy remaining between WRR values obtained from the in vitro solution method and in vivo method, which itself shows variability in results, this work provided a new insight into the in vitro testing of water resistance of sunscreens.

AB - BACKGROUND: The beryllium lymphocyte proliferation test (BeLPT), has become the principal clinical test for detecting beryllium sensitization and chronic beryllium disease. Uninterpretable BeLPT results can occur in a small but significant proportion of tests from poor lymphocyte growth (PG) or over proliferation of lymphocytes (OP). The clinical and laboratory causes of uninterpretable results are not known. METHODS: BeLPT data from the US Department of Energy-supported Former Worker Screening Program were analyzed for a 10-year period. Drivers of uninterpretable BeLPTs were investigated using multivariable models and classification techniques. RESULTS: Three participant attributes were significantly associated with PG, while OP showed no significant associations. Serum lot for the lymphocyte growth medium accounted for 21% of the variation in PG and 16% in OP. CONCLUSION: Serum lots influence the likelihood of having uninterpretable BeLPT. To better understand uninterpretable results and possibly reduce their occurrence, additional laboratory-related factors should be addressed. PMID- 29574955 TI - Hepatology Highlights.

PMID- 29574959 TI - Discrimination, harassment and non-reporting in UK medical education. AB - CONTEXT: Discrimination and harassment create a hostile environment with deleterious effects on student well-being and education. In this study, we aimed to: (i) measure prevalences and types of discrimination and harassment in one UK medical school, and (ii) understand how and why students report them. METHODS: The study used a mixed-methods design. A medical school population survey of 1318 students was carried out in March 2014. Students were asked whether they had experienced, witnessed or reported discrimination or harassment and were given space for free-text comments. Two focus group sessions were conducted to elicit information on types of harassment and the factors that influenced reporting. Proportions were analysed using the Wilson score method and associations tested using chi-squared and regression analyses. Qualitative data were subjected to framework analysis. Degrees of convergence between data were analysed. RESULTS: A total of 259 (19.7%) students responded to the survey. Most participants had experienced (63.3%, 95% confidence interval [CI]: 57.3-69.0) or witnessed (56.4%, 95% CI: 50.3-62.3) at least one type of discrimination or harassment. Stereotyping was the form most commonly witnessed (43.2%, 95% CI: 37.4-49.3). In the qualitative data, reports of inappropriate joking and invasion of personal space were common. Black and minority ethnic students had witnessed and religious students had experienced a greater lack of provision (chi2 = 4.73, p = 0.03 and chi2 = 4.38, p = 0.04, respectively). Non-heterosexual students had experienced greater joking (chi2 = 3.99, p = 0.04). Students with disabilities had experienced more stereotyping (chi2 = 13.5, p < 0.01). Female students and students in clinical years had 2.6 (95% CI: 1.3-5.3) and 3.6 (95% CI: 1.9-7.0) greater odds, respectively, of experiencing or witnessing any type of discrimination or harassment. Seven of 140 survey respondents had reported incidents (5.0%, 95% CI: 2.4-10.0). Reporting was perceived as ineffective and as potentially victimising of the reporter. CONCLUSIONS: Harassment and discrimination are prevalent in this sample and associated with gender, ethnicity, sexuality, disability and year group. Reporting is rare and perceived as ineffective. These findings have informed local developments, future strategies and the development of a national prevention policy.

AB - The aim of this study was to assess awake bruxism (AB) behaviours in a sample of healthy young adults using a smartphone-based application for a real-time report (ie, ecological momentary assessment [EMA], also called experience sampling method [ESM]). Forty-six dental students used a smartphone application that sent 15 alerts at random intervals during the day for 1 week to collect AB self reports. They had to answer on time by tapping on the display icon that refers to their current condition of jaw muscles: relaxed; teeth contact; teeth clenching; teeth grinding; jaw clenching without teeth contact (ie, bracing). The average frequency of relaxed jaw muscles, as a percentage of answers over the 7 days, was 71.7%. Teeth contact (14.5%) and jaw clenching (10.0%) were the most frequent AB behaviours. No significant gender differences were detected. Interindividual differences were quite relevant, but the overall frequency was in general only moderately variable from day-to-day. Coefficient of variation (CV) was low for the condition "relaxed jaw muscles" (0.44). At the individual level, teeth contact was the most prevalent behaviour, with a 39.1%-52.2% proportion of subjects reporting it at least once a day. During a 7-day observation period, the frequency of real-time report of AB behaviours in a sample of healthy young adults was 28.3%. The low daily variability in the average frequency value for the relaxed jaw muscles condition suggests that EMA may be a reliable strategy to get deeper into the epidemiology of oral behaviours. This investigation introduced EMA principles to the study of AB and provided data on the frequency of AB behaviours in young adults that could be compared to populations with risk/associated factors and possible clinical consequences.

AB - The aim of this study was to examine variation in suicide ideation and its relationship to risk of suicide attempt in the subsequent 90 days by race and ethnicity. Participants were adults who completed the Patient Health Questionnaire depression module (PHQ9) during an outpatient encounter between January 10, 2010, and December 12, 2012 (N = 509,945 patients; N = 1,228,308 completed PHQ9). Data came from the Virtual Data Warehouse from four health care systems in the Mental Health Research Network. The sample was majority female (73.7%), primarily 30-64 years old (60.1%), healthy (64.5% comorbidity index = 0), and over half were non-Hispanic White (52.9%). Only Asian patients (OR: 1.31; 95% CI: 1.24, 1.39) had higher odds of reporting suicide ideation when compared to non-Hispanic White people. All racial and ethnic groups had increased risk for suicide attempt with increased frequency of suicide ideation. The PHQ9 item 9 can be used as an indicator of suicide ideation and risk for suicide attempt up to 90 days after the reported ideation in racial and ethnic minority patients during routine clinical care.

AB - Epidermolysis bullosa simplex is a group of inherited disorders with allelic and locus heterogeneity in which skin fragility and blistering within the skin occur. Mutations in KRT5 and KRT14 underlie the majority of reported cases. Mutations in KLHL24, a gene that encodes KLHL24 protein, have been reported recently to cause a generalized subtype of epidermolysis bullosa simplex, presumably by increasing the degradation of keratin 14. We describe a case of KLHL24-related epidermolysis bullosa simplex and highlight the burn-like pattern of scars. PMID- 29574967 TI - Is the incidence of advanced-stage breast cancer affected by whether women attend a steady-state screening program? AB - In this cross-sectional population-based study, we assessed the incidence of advanced breast cancer based on screening attendance. Women from the Netherlands Cancer Registry were included if aged >=49 years and diagnosed with breast cancer between 2006 and 2011, and data were linked with the screening program. Cancers were defined as screen-related (diagnosed <24 months after screening) or nonscreened (all other breast cancers). Two cut-offs were used to define advanced breast cancer: TNM-stage (III-IV vs 0-I-II) and T-stage alone (>=15 mm vs <15 mm or DCIS). The incidence rates were adjusted for age and logistic regression was used to compare groups. Of the 72,612 included women diagnosed with breast cancer, 44,246 (61%) had screen-related breast cancer. By TNM stage, advanced cancer was almost three times as likely to be at an advanced TNM stage in the nonscreened group compared with the screen-related group (38 and 94 per 100,000, respectively; OR: 2.86, 95%CI: 2.72-3.00). By T-stage, the incidence of advanced cancer was higher overall, and in nonscreened women was significantly higher than in screened women (210 and 169 per 100,000; OR: 1.85, 95%CI: 1.78-1.93). Data on actual screening attendance showed that the incidence of advanced breast cancer was significantly higher in nonscreened women than in screened women, supporting the expectation that screening would cause a stage shift to early detection. Despite critical evaluations of breast cancer screening programs, our data show that breast cancer screening is a valuable tool that can reduce the disease burden in women. PMID- 29574968 TI - Predictors of childhood trajectories of overt and indirect aggression: An interdisciplinary approach. AB - The aim of this study was to advance our understanding of the development of aggression in boys and girls by testing a model combining insights from both evolutionary theory and developmental psychology. A sample of 744 children (348 girls) between six and 13 years old was recruited in schools with high deprivation indices. Half of the sample (N = 372; 40.1% girls) had received special educational services for behavioral and/or socio-emotional problems. Two trajectories for overt aggression and two trajectories for indirect aggression were identified and binomial logistic regressions were used to identify environmental predictors and sex-specific patterns of these trajectories. Results indicated that peer rejection predicted overt aggression and indirect aggression and that extraversion and male sex predicted overt aggression. The results also showed that interaction between parental practices and some child temperament traits predicted overt aggression (coercion and lack of supervision associated with extraversion or low effortful control) or indirect aggression (coercion and neglect associated with negative affect or low effortful control), and the absence of a father figure predicted high indirect aggression in girls.

PMID- 29574970 TI - Migration Study of Butylated Hydroxytoluene and Irganox 1010 from Polypropylene Treated with Severe Processing Conditions. AB - : Safety concerns have emerged over the increased use of polypropylene (PP) in food-packaging markets. Some antioxidants in PP can migrate to foods and cause undesirable effects in humans. In this study, migration behaviors of butylated hydroxytoluene (BHT) and Irganox 1010 (I-1010) in PP sheets were determined according to the US FDA migration test conditions. In particular, we tested the effects of severe conditions of food processing and storage, such as autoclave heating (sterilization at about 121 degrees C), microwave radiation (700 W), and deep freezing (-30 degrees C) on migration of antioxidants. Migrant concentrations were higher in 95% ethanol as lipid food simulant, because of the hydrophobic nature of both PP and antioxidants. Autoclave heating treatment increased migrant concentrations compared with other processing conditions. Moreover, increased migrant concentrations by deep freezing condition were attributed to the brittleness of PP at freezing temperature. Regardless of processing conditions, BHT which has a lower molecular weight, migrated faster than I-1010. PRACTICAL APPLICATION: The antioxidants with hydrophobic nature such as butylated hydroxytoluene (BHT) and Irganox 1010 (I-1010) in polypropylene sheets would be migrated to foods, which is an important issue for industrial production food packaging materials. Migration behavior was promoted by severe processing conditions such as autoclave heating, microwave radiation, freezing, and especially autoclave heating treatment led the highest migration among them. Therefore, control of chemical additive migration from polypropylene food packaging is needed for safe food processing.

AB - AIMS: To psychometrically evaluate the Impact of Nighttime Urination (INTU) questionnaire, a new patient-reported outcome measure developed to assess the impact of nocturia on health and functioning in a multicenter, behavioral modification (fluid restriction) study. METHODS: Participants aged 50-95 years with at least two voiding episodes/night for >=6 months completed voiding diaries and the INTU on 3 consecutive days during weeks 1 and 2 (same day recall) and completed the Pittsburgh Sleep Quality Index (PSQI) and Nocturia Quality of Life Questionnaire (N-QOL) at baseline and days 8 and 15. Psychometric evaluations of the INTU were conducted. RESULTS: Rasch analysis showed the INTU to be a unidimensional construct, with most items located on the severe end of the symptom severity continuum. In addition to an Overall Impact Score (10 items), exploratory factor analysis affirmed by confirmatory factor analysis identified two domains: Daytime (six items) and Nighttime (four items) Impact Scores (comparative fit index = 0.968; root mean square error of approximation = 0.08). Concurrent validity met prespecified hypotheses, indicating similarity of concepts with the PSQI (correlation [r] = 0.627) and N-QOL (r = -0.784) total scores. The INTU differentiated among patients with different nocturic episode frequencies (P < 0.05 for all three summary scores). Statistically significant decreases were observed in mean Overall and Nighttime Impact Scores at week 2 versus week 1 in responders, indicating that the instrument can detect changes in response to symptom improvements. CONCLUSIONS: The INTU questionnaire demonstrated robust measurement properties and is a suitable tool for assessing the patient-reported impact of nocturia on health and functioning. PMID- 29574973 TI - Adenosine-loaded dissolving microneedle patches to improve skin wrinkles, dermal density, elasticity and hydration. AB - OBJECTIVE: Although dissolving microneedle patches have been widely studied in the cosmetics field, no comparisons have been drawn with the topical applications available for routine use. In this study, two wrinkle-improving products, adenosine-loaded dissolving microneedle patches and an adenosine cream, were evaluated for efficacy, with respect to skin wrinkling, dermal density, elasticity, and hydration, and safety in a clinical test on the crow's feet area. METHODS: Clinical efficacy and safety tests were performed for 10 weeks on 22 female subjects with wrinkles around their eyes. The adenosine-loaded dissolving microneedle patch was applied once every 3 days, in the evening, for 8 weeks to the designated crow's feet area. The adenosine cream was applied two times per day, in the morning and evening, for 8 weeks to the other crow's feet area. Skin wrinkling, dermal density, elasticity, and hydration were measured by using PRIMOS(r) premium, Dermascan(r) C, Cutometer(r) MPA580, and Corneometer(r) CM 825, respectively. In addition, subjective skin irritation was evaluated by self observation, and objective skin irritation was assessed through expert interviews. RESULTS: The adenosine-loaded dissolving microneedle patches had a similar or better efficacy than the adenosine cream. Both groups showed statistically significant efficacy for almost all parameters (P < 0.05). The dissolving microneedle patches had a long-lasting effect on the average wrinkle depth (P < 0.05), only showed efficacy in dermal density (P < 0.05), had an early improving effect on elasticity (P < 0.05), and demonstrated better hydration efficacy (P < 0.001). No adverse effects were observed in either group during the test period. CONCLUSIONS: In the clinical efficacy test of four skin-improvement parameters, adenosine-loaded dissolving microneedle patches showed the same or better effect than the adenosine cream, although the weekly adenosine dose was 140 times lower. The dissolving microneedle patches caused no adverse reactions. These adenosine-loaded dissolving microneedle patches are expected to be safe, effective, and novel cosmetics for skin improvement. PMID- 29574974 TI - A pharmacological rationale for improved everolimus dosing in oncology and transplant patients. AB - AIMS: Everolimus is a drug from the class of mammalian target of rapamycin inhibitors used for both immunosuppressant and oncological indications. We postulate that there is room for improvement of dosing, as the optimal immunosuppressive dose in calcineurin-free regimens is unknown and since the once daily dosing regimen for oncological indications is often associated with treatment-limiting toxicity. METHODS: We developed a mechanistic population pharmacokinetic model for everolimus in cancer and transplant patients and explored alternative dosing regimens. RESULTS: We found that formulation did not influence bioavailability and that use of >20 mg prednisolone daily increased everolimus clearance. In transplant patients, the approved dose of 0.75-1 mg twice daily (BID) results in subtherapeutic trough levels (<6 MUg l-1 ) and that a higher starting dose of 2.25-3 mg BID is required. CONCLUSION: For oncological indications, our results encourage the investigation of dosing everolimus 3.75 mg BID in terms of superiority in safety and noninferiority in efficacy. PMID- 29574975 TI - LncRNA FLVCR1-AS1 acts as miR-513c sponge to modulate cancer cell proliferation, migration, and invasion in hepatocellular carcinoma. AB - In the present study, we aimed to search for dysregulated lnRNAs in Hepatocellular carcinoma (HCC) tissues, and analyze the relationship of its expression level with the clinicopathological feature and patient prognosis. The biological function of FLVCR1-AS1, the identified lncRNA, in the process of HCC development, and progression was investigated in vitro and in vivo. The underlying molecular mechanism was further explored. We determined FLVCR1-AS1 expression in HCC tissues and peri-tumor tissues by bioinformatic analysis, qRT PCR, Northern blot and in situ hybridization. The relationship between FLVCR1-AS1 expression level and prognosis was determined by analyzing clinical samples. The effects of FLVCR1-AS1 knockdown on HCC cell proliferation, apoptosis, migration, and invasion were investigated by CCK8, FACS, and tanswell assay, respectively. Tumor xenograft model was used to determine the influence of down-regulated FLVCR1-AS1 on tumor growth and metastasis. lncRNA FLVCR1-AS1 was extremely up regulated in HCC tissues and cell lines. FLVCR1-AS1 expression level was positively correlated with tumor severity. FLVCR1-AS1 knockdown remarkably inhibited HCC cell proliferation, migration, and invasion in vitro and in vivo while induced cell apoptosis. In mechanism, FLVCR1-AS1 acted as a competitive endogenous RNAs to sponge miR-513c which targeted the mRNA of MET for degradation. By directly sponging miR-513c, FLVCR1-AS1 increased MET expression in HCC, and then promoted HCC progression. It was demonstrated that FLVCR1-AS1 played a positive role in HCC development and progression according to the study in its mechanism, function and clinical manifestation, so that it could be expected to become a new target in HCC prevention and treatment. PMID- 29574977 TI - A systematic review and meta-analysis: Effectiveness of internet empowerment based self-management interventions on adults with metabolic diseases. AB - AIM: To synthesize the effects of Internet empowerment-based self-management interventions on adults with metabolic diseases. BACKGROUND: Metabolic diseases are prevalent and burden healthcare systems; they have become a major health problem worldwide. The effects of IESMIs on lifestyle changes have been shown to improve adults' physiological and psychological conditions. However, we found no systematic review evaluating these effects. DESIGN: Systematic review and meta analysis of randomized and non-randomized controlled trials, conducted according to the Cochrane handbook. DATA RESOURCES: A literature search was conducted using the Airiti Library, Association for Computing Machinery, CINAHL, Cochrane Library, Embase, ProQuest, PubMed/MEDLINE and Index of the Taiwan Periodical Literature System databases (earliest-June 2016). REVIEW METHODS: Two reviewers used the Cochrane Collaboration bias assessment tool to assess the methodological quality of included studies. Extracted data were entered and analysed using RevMan 5.3.5 software. Inverse variance was used to estimate effect sizes. Weighted and standardized mean differences with 95% confidence intervals were calculated using a random effects model. Subgroup and sensitivity analyses were performed. RESULTS: Twenty-one randomized controlled trials were reviewed. Meta analysis showed that the intervention significantly improved adults' exercise habits, glycated haemoglobin (HbA1c) levels, body weight, empowerment levels and quality of life. CONCLUSION: The intervention significantly improve the health status of adults with metabolic diseases, in particular their exercise habits, HbA1c levels, body weight, empowerment and quality of life. The intervention provides more convenient and faster access to healthcare for busy individuals with time constraints. These results suggest that healthcare professionals could develop accessible and friendly interactive online interfaces for patients to expand the use of these interventions in the clinical setting. PMID- 29574976 TI - Database for High Throughput Screening Hits (dHITS): a simple tool to retrieve gene specific phenotypes from systematic screens done in yeast. AB - In the last decade several collections of Saccharomyces cerevisiae yeast strains have been created. In these collections every gene is modified in a similar manner such as by a deletion or the addition of a protein tag. Such libraries have enabled a diversity of systematic screens, giving rise to large amounts of information regarding gene functions. However, often papers describing such screens focus on a single gene or a small set of genes and all other loci affecting the phenotype of choice ('hits') are only mentioned in tables that are provided as supplementary material and are often hard to retrieve or search. To help unify and make such data accessible, we have created a Database of High Throughput Screening Hits (dHITS). The dHITS database enables information to be obtained about screens in which genes of interest were found as well as the other genes that came up in that screen - all in a readily accessible and downloadable format. The ability to query large lists of genes at the same time provides a platform to easily analyse hits obtained from transcriptional analyses or other screens. We hope that this platform will serve as a tool to facilitate investigation of protein functions to the yeast community. PMID- 29574978 TI - Canine total hip replacement using a cementless threaded cup and stem: a review of 55 cases. AB - OBJECTIVES: To determine the long-term results and complications associated with the Helica(r) cementless hip endoprosthesis system. MATERIALS AND METHODS: Retrospective study of 55 consecutive Helica total hip replacements performed between January 2010 and February 2015. RESULTS: A total of 55 total hip replacements were performed in 50 dogs; 45 dogs had unilateral hip replacements, and five had staged bilateral replacements. A total of 23 first-generation short femoral stems were implanted in 22 dogs, of which nine cases (39%) experienced complications and 19 (86%) recovered satisfactorily when revisions were included; 31 second-generation femoral stems were implanted in 28 dogs, of which 10 cases (32%) experienced complications, and 26 (93%) made satisfactory recoveries, including revisions. In 36 dogs for which data were available, postoperative Liverpool Osteoarthritis in Dogs scores were significantly reduced compared to preoperative scores. Complications occurred in a total of 19 cases (34.5%; 95% confidence interval: 22 to 47.1%); the most common was aseptic loosening of the femoral stem [11 cases (20%; 95% confidence interval: 9.4 to 30.6%)]. Following multivariable analysis, no risk factors were identified for overall complications, but there was a significant association of implant type (first generation short stem) with loosening (odds ratio 4.9, 95% confidence interval: 1.1 to 22.1, P=0.034). CLINICAL SIGNIFICANCE: This study found the Helica hip endoprosthesis system to be effective in the management of hip dysplasia and osteoarthritis in dogs. Aseptic loosening of the femoral stem remains the most common complication but appears to have been significantly reduced with the introduction of the second-generation stem.

PMID- 29574980 TI - Blockade of the renin-angiotensin-aldosterone system in patients with arrhythmogenic right ventricular dysplasia: A double-blind, multicenter, prospective, randomized, genotype-driven study (BRAVE study). AB - Arrhythmogenic right ventricular dysplasia (ARVD) is a rare cardiomyopathy characterized by the progressive replacement of cardiomyocytes by fatty and fibrous tissue in the right ventricle (RV). These infiltrations lead to cardiac electrical instability and ventricular arrhythmia. Current treatment for ARVD is empirical and essentially based on treatment of arrhythmia. Thus, there is no validated treatment that will prevent the deterioration of RV function in patients with ARVD. The aim of the BRAVE study is to evaluate the effect of ramipril, an angiotensin-converting enzyme inhibitor, on ventricular myocardial remodeling and arrhythmia burden in patients with ARVD. Despite the fact that myocardial fibrosis is one of the structural hallmarks of ARVD, no study has tested an antifibrotic drug in ARVD patients. The trial is a double-blind, parallel, multicenter, prospective, randomized, phase 4 drug study. Patients will be randomized into 2 groups, ramipril or placebo. The 120 patients (60 per group) will be enrolled by 26 centers in France. Patients will be followed up every 6 months for 3 years. The 2 co-primary endpoints are defined as the difference of telediastolic RV volume measured by magnetic resonance imaging between baseline and 3 years of follow-up, and the change in arrhythmia burden during the 3 years of follow-up. A decrease in RV and/or left ventricular deterioration and in arrhythmia burden are expected in ARVD patients treated with ramipril. This reduction will improve quality of life of patients and will reduce the number of hospitalizations and the risk of terminal heart failure. PMID- 29574981 TI - Phosphatidylcholine 36:1 concentration decreases along with demyelination in the cuprizone animal model and in post-mortem multiple sclerosis brain tissue. AB - Multiple sclerosis is a demyelinating and inflammatory disease. Myelin is enriched in lipids, and more specifically, oleic acid. The goal of this study was to evaluate the concentration of oleic acid following demyelination and remyelination in the cuprizone model, test if these changes occurred in specific lipid species, and whether differences in the cuprizone model correlate with changes observed in post-mortem human brains. Eight-week-old C57Bl/6 mice were fed a 0.2% cuprizone diet for 5 weeks and some animals allowed to recover for 11 days. Demyelination, inflammation, and lipid concentrations were measured in the corpus callosum. Standard fatty acid techniques and liquid chromatography combined with tandem mass spectrometry were performed to measure concentrations of fatty acids in total brain lipids and a panel of lipid species within the phosphatidylcholine (PC). Similar measurements were conducted in post-mortem brain tissues of multiple sclerosis patients and were compared to healthy controls. Five weeks of cuprizone administration resulted in demyelination followed by significant remyelination after 11 days of recovery. Compared to control, oleic acid was decreased after 5 weeks of cuprizone treatment and increased during the recovery phase. This decrease in oleic acid was associated with a specific decrease in the PC 36:1 pool. Similar results were observed in human post-mortem brains. Decreases in myelin content in the cuprizone model were accompanied by decreases in oleic acid concentration and is associated with PC 36:1 suggesting that specific lipids could be a potential biomarker for myelin degeneration. The biological relevance of oleic acid for disease progression remains to be verified. PMID- 29574982 TI - Reduced root cortical burden improves growth and grain yield under low phosphorus availability in maize. AB - Root phenes and phene states that reduce the metabolic cost of soil exploration may improve plant growth under low phosphorus availability. We tested the hypothesis that under low phosphorus, reduced living cortical area (LCA) would increase soil exploration, phosphorus capture, biomass, and grain yield. Maize genotypes contrasting in LCA were grown in the field and in greenhouse mesocosms under optimal and suboptimal phosphorus regimes. Percent LCA in nodal roots ranged from 25% to 67%. Plants with 0.2 mm2 less LCA under low phosphorus had 75% less root segment respiration, 54% less root phosphorus content, rooted 20 cm deeper, allocated up to four times more roots between 60 and 120 cm depth, had between 20% and 150% more biomass, 35-40% greater leaf phosphorus content, and 60% greater grain yield compared with plants with high LCA. Low-LCA plants had up to 55% less arbuscular mycorrhizal colonization in axial roots, but this decrease was not correlated with biomass or phosphorus content. The LCA components cortical cell file number and cortical cell size were important for biomass and phosphorus content under low phosphorus. These results are consistent with the hypothesis that root phenes that decrease the metabolic cost of soil exploration are adaptive under phosphorus stress.

Because antitumor agents are possible to combine with antifungal agents in clinical, it is necessary to study drug-drug interaction between antitumor agents and antifungal agents. The aim of the study was to explore a method for the simultaneous determination of voriconazole and docetaxel in plasma and investigate pharmacokinetic interaction of voriconazole and docetaxel in rats. A precise and reliable method using liquid chromatography tandem mass spectrometry (LC-MS/MS) was established for the simultaneous measure of docetaxel and voriconazole in rat plasma after liquid liquid extraction with ethyl acetate. The method was fully validated and successfully applied to a pharmacokinetic interaction study of docetaxel and voriconazole in rats after single or combined administration. We found that the AUC of each drug after coadministration increased compared with that after the single administration, which might be caused by interaction at the absorption stage or the competitive inhibition on the metabolic enzymes. This established method can be utilized to study the detailed mechanism of the drug-drug interaction and guide rational drug use in the clinic. PMID- 29574984 TI - Endopeptidase inhibition attenuates the contraction induced by big endothelin-1 of isolated human penile erectile tissue. AB - Peptides, such as C-type natriuretic peptide (CNP), vasoactive intestinal polypeptide (VIP) and endothelin 1 (ET-1), are involved in the control of penile erectile tissue (corpus cavernosum = CC). Inhibiting the degradation of CNP and VIP or conversion of Big ET-1 into ET-1 by endopeptidase enzymes should result in an enhancement of CC smooth muscle relaxation. Using the tissue bath technique, responses of isolated CC, challenged by noradrenaline (NA, 1 MUm), to increasing concentrations of the endopeptidase inhibitor KC 12615 (1 nm - 10 MUm), CNP and VIP (0.1 nm - 1 MUm), were investigated. Effects of CNP, VIP and Big ET-1 (0.1 nm - 100 nm) on the tissue tension were also evaluated following pre-exposure to 10 MUm of KC 12615. Big ET-1 induced contraction of the CC amounting to a force generation of 1,200 mg. The contraction was attenuated in the presence of KC 12615 by 35% and 50%, respectively. The tension induced by NA was reversed by VIP and CNP to 38.7% +/- 15.8% and 61% +/- 13%, respectively, of the initial force. The findings might be of significance with regard to future pharmacological treatment options for male ED, where an endothelial dysfunction exists. PMID- 29574986 TI - Outcome of pregnancies in a large cohort of women with acromegaly. AB - OBJECTIVE: To assess the outcome of pregnancies in a large cohort of women with acromegaly. DESIGN AND METHODS: This is a retrospective analysis of 31 pregnancies in 20 patients with acromegaly. RESULTS: Twenty-seven pregnancies resulted in healthy offspring, and 4 resulted in abortion. Three patients underwent transsphenoidal surgery during pregnancy. IGF-1 levels remained elevated during pregnancy in 4 pregnancies and normalized in 23 cases. Fifteen cases were followed during pregnancy without any medical or surgical treatment, and 13 of these exhibited normal IGF-1 levels. Before or during pregnancy, somatostatin receptor ligands usage was not associated with higher risk for adverse outcomes. Arterial hypertension worsening (45%) and impairment of glucose levels (32%) were the most common complications during pregnancies. There were no maternal or neonatal deaths. One woman delivered twins. Two cases of congenital malformations and one with foetal macrosomia were observed. Caesarean delivery was performed in sixteen cases. CONCLUSION: Our study confirms the impact of gestation on IGF-1 levels. However, it also indicates that acromegaly still holds an increased risk for worsening of comorbidities, especially in uncontrolled patients.

PMID- 29574988 TI - Effects of postoperative pain management educational interventions on the outcomes of parents and their children who underwent an inpatient elective surgery: A randomized controlled trial. AB - AIM: To examine the effects of a postoperative pain management educational intervention on the outcomes of parents and their children who underwent inpatient elective surgery. BACKGROUND: Equipping parents with knowledge and skills to manage their children's postoperative pains is essential. Very limited studies have examined the effects of educational interventions on parents' knowledge, attitudes and use of pharmacological and non-pharmacological pain relief methods. DESIGN: Three-group pre- and post-test randomized controlled trial. METHODS: Parent-child pairs (N = 152) were recruited from September 2013 January 2015 and randomly assigned to either the control group or one of the two intervention groups. Valid and reliable instruments and diary entries were used to collect data at the baseline, 6, 12 and 24 hr and 2 weeks after the surgery. IBM SPSS 23.0 was used to analyse the data. RESULTS: Parents reported moderate levels of knowledge, attitudes, pain relief methods used and children's postoperative pain. Except for parents' knowledge, types and frequencies of non pharmacological methods used, there were no statistically significant differences among the three groups in parents' attitudes on pain management and pain medication, their uses of pain relief strategies (questionnaire data), satisfaction with postoperative pain management and children's worst postoperative pain in 2 weeks after surgery. CONCLUSION: Education seemed effective in improving parents' knowledge and use of non-pharmacological methods, but not attitudes, satisfaction with pain management and children's postoperative pain. Future studies are needed to develop modern digitalized ways for educating and supporting parents to optimize their children's postoperative pain management.

PMID- 29574990 TI - The effect of combined pulsed wave low-level laser therapy and mesenchymal stem cell-conditioned medium on the healing of an infected wound with methicillin resistant Staphylococcal aureus in diabetic rats. AB - This study aims to investigate the combined effects of Pulsed wave low-level laser therapy (PW LLLT) and human bone marrow mesenchymal stem cell-conditioned medium (hBM-MSC-CM) on the microbial flora and tensiometrical properties of an infected wound model with methicillin-resistant staphylococcal aureus (MRSA) in an experimental model for Type 1 diabetes mellitus (TIDM). TIDM was induced in rats by streptozotocin (STZ). One full-thickness excision was made on the backs of the rats. Next, the rats were divided into the following groups: Group 1 was the control (placebo) group; Group 2 received hBM-MSCs-CM four times; Group 3 were laser PWLLLT (890 nm, 80 Hz, 0.2 J/cm2 ); and Group 4 received hBM-MSCs-CM +LASER. Wounds were infected with MRSA. Microbiological examinations were performed on days 4, 7, and 15. Tensiometerical examinations were carried out on the 15th day. One-way analysis of variance showed that laser and CM alone and/or in combination significantly increases the tensiomerical properties of the repaired wounds compared with control wounds. A combination of PW laser and CM was statistically more effective than other treated groups. Two-way analysis of variance showed that laser and CM alone and/or in combination significantly decreases the colony-forming units (CFUs) compared with the control group. The application of hBM-MSC-CM and PWlaser alone and/or together significantly accelerates the wound-healing process in MRSA-infected cutaneous wounds in TI DM in rats. Additionally, a combined application of hBM-MSC-CM and PWlaser demonstrates a synergistic effect on the wound-healing process in MRSA-infected cutaneous wounds in Type I DM rats.

AB - Diclofenac is a Non-Steroidal Anti-inflammatory drug which is used as an analgesic. It is known to cause heptotoxicity on over dose and long term usage. Madhuca longifolia is an evergreen tree found widely in India that is known to have several ethnomedical uses. The aim of our study is to evaluate the beneficial effect of the aqueous leaf extract of M. longifolia against diclofenac induced toxicity. Rats were dived into five groups of six rats each. Group-I was normal control. Group-II was administered with diclofenac (50 mg/kg. b.w./day, i.p) on 4th and 5th day. Group-III rats were treated with aqueous leaf extract of M. longifolia (500 mg/kg b.w./day, oral) for 5 consecutive days and diclofenac (50 mg/kg. b.w./day, i.p) was given on 4th and 5th day. Silymarin (25 mg/kg. b.w./day, oral) was used as standard drug which was given to the rats of group-IV along with diclofenac on 4th and 5th day. Aqueous leaf extract of M. longifolia (500 mg/kg b.w./day, oral) alone was administered in group-V. After the study period, the rats were evaluated for liver enzyme markers, antioxidant parameters, histopathological changes, and cytokines levels. The hepatic proinflammatory mediator cytokines like TNF-alpha, IL-6, and IL-1beta were evaluated through ELISA. The protein expression of Caspase-3, COX-2, and NF-kappaB were analysed through Western blotting techniques. Aqueous leaves extract of M. longifolia was able to normalize the changes caused by diclofenac. Current study indicatesthe protective effect of the aqueous leaves extract of M. longifolia against diclofenac-induced toxicity. PMID- 29574992 TI - Altered DNA methyltransferases promoter methylation and mRNA expression are associated with tamoxifen response in breast tumors. AB - Tamoxifen is a standard anti-hormone treatment in estrogen receptor positive breast carcinoma patients. Unfortunately, about 50% of patients relapse during treatment. Promoter hypermethylation contributes to the epigenetic modulation of tamoxifen resistance-related genes. To evaluate the contribution of DNMTs expression and their promoter methylation as diagnostic biomarkers in development of breast malignancy and tamoxifen resistance, the present study was designed and 107 breast tumors and normal breast tissues were recruited. Methylation-specific high-resolution melt curve analysis and quantitative RT-PCR were performed to evaluate DNMTs promoter methylation and mRNA expression, respectively. Our results indicated that DNMT3A and DNMT3B promoters were demethylated in breast tumors as compared to control tissues. The mRNA expression levels of all three DNMTs were significantly increased in tumor specimens in comparison to control tissues (p < 0.05). Among tumor tissues, DNMT3A promoter methylation was significantly higher in tamoxifen sensitive patients (p = 0.001). Overexpression of DNMT3A (p = 0.037) and DNMT3B (p < 0.001) mRNA were observed in tamoxifen resistance group. Multivariate logistic regression analysis indicated that low methylation status of DNMT3A and overexpression of DNMT3B could be as independent predictors of disease recurrence. Multivariate Cox regression analysis, revealed that high methylation status of DNMT3A could be an independent and favorable predictor for disease free survival (p = 0.002) and overall survival (p = 0.026); high expression of DNMT1 (p = 0.03) remained significant and unfavorable predictive factor for overall survival. In conclusion, our data for the first time indicated that low methylation status of DNMT3A promoter and overexpression of DNMT3B could contribute to disease recurrence in tamoxifen-treated breast cancer patients. PMID- 29574993 TI - Marital status and outcomes after myocardial infarction: Observations from the Canadian Observational Antiplatelet Study (COAPT). AB - While divorced or living alone, patients with stable cardiovascular disease are at increased risk for adverse cardiovascular events. The importance of marital status following a myocardial infarction (MI) is less clear. We hypothesized that marital status may affect cardiovascular outcomes following MI. We analyzed outcomes among patients with MI who underwent percutaneous coronary intervention from the Canadian Observational Antiplatelet Study (COAPT). Marital status was categorized into 3 groups: married/common-law patients living together; never married; and divorced, separated, or widowed patients. Patients were followed for 15 months and our primary outcome was the occurrence of a major adverse cardiovascular event (MACE), defined as a composite of mortality, repeat acute MI, stroke, or urgent coronary revascularization. Multivariable logistic regression models were performed, with married/common-law patients living together considered the reference group. Among 2100 patients included in analyses, 1519 (72.3%) were married/common-law patients living together, 358 (17.1%) were separated/divorced/widowed, and 223 (10.6%) patients were never married. Dual antiplatelet therapy use after 15 months was similar across groups (75.4%, 77.8%, and 73.6%, respectively). The risk of MACE after 15 months was similar among married patients living together (12.7%; referent) compared with patients who were never married (13.9%; adjusted odds ratio: 1.09, 95% confidence interval: 0.58-2.07, P = 0.79) and patients separated/divorced/widowed (14.3%; adjusted odds ratio: 0.71, 95% confidence interval: 0.40-1.25, P = 0.23). Similarly, the risk of individual endpoints, including mortality, was similar across the 3 groups. Among patients stabilized following an MI, we found no association between marital status and 15-month outcomes. PMID- 29574994 TI - Worse Health-Related Quality of Life at long-term follow-up in patients with Cushing's disease than patients with cortisol producing adenoma. Data from the ERCUSYN. AB - OBJECTIVE: Hypercortisolism in Cushing's syndrome (CS) is associated with impaired health-related quality of life (HRQoL), which may persist despite remission. We used the data entered into the European Registry on Cushing's syndrome (ERCUSYN) to evaluate if patients with CS of pituitary origin (PIT-CS) have worse HRQoL, both before and after treatment than patients with adrenal causes (ADR-CS). METHODS: Data from 595 patients (492 women; 83%) who completed the CushingQoL and/or EQ-5D questionnaires at baseline and/or following treatment were analysed. RESULTS: At baseline, HRQoL did not differ between PIT-CS (n = 293) and ADR-CS (n = 120) on both EuroQoL and CushingQoL. Total CushingQoL score in PIT-CS and ADR-CS was 41 +/- 18 and 44 +/- 20, respectively (P = .7). At long time follow-up (>1 year after treatment) total CushingQoL score was however lower in PIT-CS than ADR-CS (56 +/- 20 vs 62 +/- 23; P = .045). In a regression analysis, after adjustment for baseline age, gender, remission status, duration of active CS, glucocorticoid dependency and follow-up time, no association was observed between aetiology and HRQoL. Remission was associated with better total CushingQoL score (P < .001), and older age at diagnosis with worse total score (P = .01). Depression at diagnosis was associated with worse total CushingQoL score at the last follow-up (P < .001). CONCLUSION: PIT-CS patients had poorer HRQoL than ADR-CS at long-term follow-up, despite similar baseline scoring. After adjusting for remission status, no interaetiology differences in HRQoL scoring were found. Age and presence of depression at diagnosis of CS may be potential predictors of worse HRQoL regardless of CS aetiology. PMID- 29574996 TI - Effect of NaHCO3 treatments on the activity of cell-wall-degrading enzymes produced by Penicillium digitatum during the pathogenesis process on grapefruit. AB - BACKGROUND: This study was performed to clarify the strategies of Penicillium digitatum during pathogenesis on citrus, assessing, on albedo plugs, the effects of treatment with sodium bicarbonate (NaHCO3 ), at two different pH values (5 and 8.3), on cell-wall-degrading enzyme activity over a period of 72 h. RESULTS: Treatment with NaHCO3 , under alkaline pH, delayed the polygalacturonase activity for 72 h, or 48 h in the case of the pectin lyase, compared with the control or the same treatment at pH 5. In contrast, pectin methyl esterase activity rapidly increased after 24 h, in plugs dipped in the same solution. In this case, the activity remained higher than untreated or pH 5-treated plugs up to 72 h. CONCLUSION: The rapid increase in pectin methyl esterase activity under alkaline conditions is presumably the strategy of the pathogen to lower the pH, soon after the initiation of infection, in order to restore an optimal environment for the subsequent polygalacturonase and pectin lyase action. In fact, at the same time, a low pH delayed the enzymatic activity of polygalacturonase and pectin lyase, the two enzymes that actually cleave the alpha-1,4-linkages between the galacturonic acid residues.

AB - AIM: To investigate whether peer support would reduce diabetes distress and improve glycaemic control when added to usual diabetes education among adults with Type 2 diabetes in China. METHODS: We conducted a cluster randomized trial involving 400 adults with Type 2 diabetes from eight communities in Nanjing. All participants received usual education for an average of 2 h each month from physicians, certified diabetes educators, dieticians, psychologists and podiatric nurses. Peer support was led by trained peer leaders and included diabetes knowledge- and skills-sharing at least once a month, as well as peer-to-peer communication. The primary outcome was diabetes distress measured using the Diabetes Distress Scale at 12 months. Secondary outcomes included fasting plasma glucose, 2-h postprandial glucose and HbA1c concentration. Outcome data were collected from all participants at baseline, 6 months and 12 months. RESULTS: From 2012 to 2013, there were 200 participants in each study arm at baseline. Compared with the usual education arm, the peer support with usual education arm had greater reductions in regimen-related distress (1.4 +/- 0.6 vs 1.2 +/- 0.4; P=0.004) and total distress (1.3 +/- 0.4 vs 1.2 +/- 0.3; P=0.038) at 6 months. At 12 months, the scores for emotional burden (1.2 +/- 0.3 vs 1.4 +/- 0.6; P=0.002), physician-related distress (1.1 +/- 0.3 vs 1.3 +/- 0.4; P=0.001) and total scores (1.2 +/- 0.3 vs 1.3 +/- 0.4; P=0.002) were significantly lower in the peer support with usual education arm than in the usual education arm. Fasting plasma glucose levels were lower in the peer support with usual education arm than in the usual education arm at 6 months (7.5 +/- 1.95 vs 8.0 +/- 2.2; P=0.044) and 12 months (7.0 +/- 2.3 vs 7.6 +/- 1.5; P=0.008). CONCLUSIONS: Beyond the benefits of usual education, peer support was effective in reducing diabetes distress for Type 2 diabetes mellitus. (Clinical Trials Registry no: NCT02119572). PMID- 29574997 TI - Fractional ablative carbon dioxide laser followed by topical sodium stibogluconate application: A treatment option for pediatric cutaneous leishmaniasis. AB - BACKGROUND: Leishmaniasis is a protozoan zoonotic parasitic infection with cutaneous, mucocutaneous, and visceral manifestations. Israel is endemic for cutaneous leishmaniasis, which is a self-limited disease but is associated with scarring, which is often a source of psychological and social burden for patients. Scars can be especially devastating for children and teenagers. A wide range of physical and medical approaches is used to treat cutaneous leishmaniasis, among which intralesional injections of sodium stibogluconate rank among the most frequently used. Unfortunately, despite being effective, this therapeutic modality can be very painful. Fractional ablative laser creates a controlled mesh-like pattern of tissue ablation in the skin that promotes dermal remodeling and collagen production while at the same time facilitating enhanced delivery of topically applied medications. METHODS: Patients were treated with fractional ablative carbon dioxide laser followed by immediate topical application of sodium stibogluconate. All children were diagnosed with cutaneous leishmaniasis prior to treatment initiation.. RESULTS: Ten children were treated. One leishmania tropica-positive girl failed to respond. The other nine patients achieved clinical cure and demonstrated good to excellent final cosmesis. Self rated patient satisfaction and tolerance were high No adverse effects were observed or reported during treatment. CONCLUSION: Fractional ablative carbon dioxide laser followed by topical sodium stibogluconate application appears to be a safe and promising treatment for cutaneous leishmaniasis infection in children. Future controlled studies are required to validate these findings and compare this technique with traditional approaches. PMID- 29574998 TI - Safety and efficacy of enhanced recovery after surgery (ERAS) programs in patients undergoing hepatectomy: A prospective randomized controlled trial. AB - BACKGROUND AND AIM: Enhanced recovery after surgery (ERAS) programs, following a variety of perioperative treatments with evidence-based medical evidence, has indicated its validity to accelerate rehabilitation in a wide variety of surgical procedures. This randomized controlled trial (RCT) study was implemented to verify the safety and efficacy of the perioperative effects in patients undergoing hepatectomy with ERAS or with conventional surgery (CS). METHODS: From August 2016 to November 2017, according to the inclusion criteria, 160 patients with liver diseases were suitable for participating in this experiment. Patients before liver resection were randomized into ERAS group (n = 80) and CS group (n = 80), and then the outcome measures were compared between the two groups. RESULTS: Enhanced recovery after surgery group had significantly less complications than CS group (P = .009). Compared with CS group, patients in ERAS group had low peak of WBCs in postoperative day (POD1), ALT in POD1 and POD3 (P < .05), high value of ALB in POD3 and POD5 (P < .05), less pain and higher patient satisfaction (P < .001), earlier exhaust, oral feeding, ambulation and extubation time (P < .05),and also had less hospital stay and cost (P < .001). There were no significant differences in readmission rate (<30 days) between two groups (P = .772). CONCLUSIONS: Enhanced recovery after surgery programs applied to patients undergoing hepatectomy can safely and effectively relieve stress response, reduce the incidence of complications, improve patient satisfaction, accelerate patient recovery, reduce financial burden, and bring economic benefits. PMID- 29574999 TI - Epidemiological and clinical features of rosacea in Korea: A multicenter cross sectional study. AB - Rosacea is a common chronic inflammatory skin condition. Although several epidemiological and etiologic studies with large sample sizes have been conducted on Caucasians, such data regarding Asian populations are lacking. A total of 580 patients diagnosed with rosacea were enrolled from October 2014 to February 2015 at 14 general hospitals. Questionnaires, including the standard classification and grading system, were used for evaluation. The average age of the patients was 47.9 years. While 83.8% of patients revealed a single subtype, 16.2% of patients revealed mixed subtypes showing two or more subtypes simultaneously. Erythematotelangiectatic rosacea (ETR) was the most prevalent subtype. ETR combined with papulopustular rosacea showed the highest proportion in the mixed subtype group. Mild severity was revealed in 71.9% of patients. The most common aggravating factor was emotional changes (51.7%), followed by stress (48.4%). Approximately half of the patients (47.4%) showed relatively low awareness of rosacea. By identifying the epidemiological and etiologic features in Korea, we can suggest valuable clinical avenues for research, education and awareness among rosacea patients. PMID- 29575000 TI - Validated LC-MS/MS method for the quantification of sciadopitysin in rat plasma and its application to pharmacokinetic and bioavailability studies in vivo. AB - A sensitive and rapid LC-MS/MS method was developed and validated for quantitation of sciadopitysin in rat plasma using amentoflavone as an internal standard. Sample processing was accomplished after deproteinization with 150 MUL aliquot of acetonitrile. Chromatographic separation was achieved using an Agela C18 column with an isocratic mobile phase comprising 2 mm ammonium acetate acetonitrile (35:65, v/v) at a flow rate of 0.4 mL/min. Detection was performed by selection reaction monitoring on a triple-quadrupole mass spectrometer following the transitions m/z 579 -> 547 and 537 -> 375 for sciadopitysin and internal standard, respectively, in the negative ionization mode. The calibration curve was linear from 2.90 to 1160 ng/mL for sciadopitysin. Intra- and inter-day precisions were in the ranges 4.1-11.4 and 5.7-9.1% for sciadopitysin. Sciadopitysin was stable under different stability conditions. The validated assay was applied to pharmacokinetic and bioavailability studies in rats. PMID- 29575001 TI - Aphid (Myzus persicae) feeding on the parasitic plant dodder (Cuscuta australis) activates defense responses in both the parasite and soybean host. AB - Dodders (Cuscuta spp.) are shoot holoparasites, whose haustoria penetrate host tissues to enable fusion between the parasite and host vascular systems, allowing Cuscuta to extract water, nutrients and other molecules from hosts. Aphids are piercing-sucking herbivores that use specialized stylets to feed on phloem sap. Aphids are known to feed on Cuscuta, but how Cuscuta and its host plant respond to aphids attacking the parasite was unknown. Phytohormone quantification, transcriptomic analysis and bioassays were performed to determine the responses of Cuscuta australis and its soybean (Glycine max) hosts to the feeding of green peach aphid (GPA; Myzus persicae) on C. australis. Decreased salicylic acid levels and 172 differentially expressed genes (DEGs) were found in GPA-attacked C. australis, and the soybean hosts exhibited increased jasmonic acid contents and 1015 DEGs, including > 100 transcription factor genes. Importantly, GPA feeding on C. australis increased the resistance of the soybean host to subsequent feeding by the leafworm Spodoptera litura and soybean aphid Aphis glycines, resulting in 21% decreased leafworm mass and 41% reduced aphid survival rate. These data strongly suggest that GPA feeding on Cuscuta induces a systemic signal, which is translocated to hosts and activates defense against herbivores. PMID- 29575002 TI - A defined, plant-based diet utilized in an outpatient cardiovascular clinic effectively treats hypercholesterolemia and hypertension and reduces medications. AB - BACKGROUND: Cardiovascular disease (CVD) is a major economic burden in the United States. CVD risk factors, particularly hypertension and hypercholesterolemia, are typically treated with drug therapy. Five-year efficacy of such drugs to prevent CVD is estimated to be 5%. Plant-based diets have emerged as effective mitigators of these risk factors. HYPOTHESIS: The implementation of a defined, plant-based diet for 4 weeks in an outpatient clinical setting may mitigate CVD risk factors and reduce patient drug burden. METHODS: Participants consumed a plant-based diet consisting of foods prepared in a defined method in accordance with a food classification system. Participants consumed raw fruits, vegetables, seeds, and avocado. All animal products were excluded from the diet. Participant anthropometric and hemodynamic data were obtained weekly for 4 weeks. Laboratory biomarkers were collected at baseline and at 4 weeks. Medication needs were assessed weekly. Data were analyzed using paired-samples t tests and 1-way repeated-measures ANOVA. RESULTS: Significant reductions were observed for systolic (-16.6 mmHg) and diastolic (-9.1 mmHg) blood pressure (P < 0.0005), serum lipids (P <= 0.008), and total medication usage (P < 0.0005). Other CVD risk factors, including weight (P < 0.0005), waist circumference (P < 0.0005), heart rate (P = 0.018), insulin (P < 0.0005), glycated hemoglobin (P = 0.002), and high-sensitivity C-reactive protein (P = 0.001) were also reduced. CONCLUSION: A defined, plant-based diet can be used as an effective therapeutic strategy in the clinical setting to mitigate cardiovascular risk factors and reduce patient drug burden.

PMID- 29575004 TI - A simple and selective LC-MS/MS method for quantification of ikarisoside A in rat plasma and its application to a pharmacokinetic study. AB - Ikarisoside A is a natural flavonoid isolated from Epimedium plants. To further evaluate its medicinal potential, a sensitive and robust LC-MS/MS method was developed and validated for the assay of ikarisoside A in rat plasma. Orientin was used as an internal standard. The electrospray ionization was operated in its negative ion mode while ikarisoside A and IS were measured by selected reaction monitoring using precursor-to-product ion transitions of m/z 499.1 -> 353.0 and m/z 446.9 -> 327.6, respectively. This LC-MS/MS method had good sensitivity (LLOQ = 1.5 ng/mL), accuracy (both intra- and inter-day RE <= +/-11.9%) and precision (both intra- and inter-day RSD <=8.5%). The pharmacokinetics of ikarisoside A was subsequently profiled in Sprague-Dawley rats. Following oral administration (35 mg/kg), ikarisoside A reached maximum plasma concentration (Cmax , 207.6 +/- 96.7 ng/mL) attained at 1.10 +/- 0.42 h. Following oral administration, the clearance and terminal half-life were 42.9 +/- 26.5 L/h/kg and 3.15 +/- 0.80 h by oral route, respectively. PMID- 29575005 TI - Axillary Sonography of the Shoulder: An Adjunctive Approach. AB - Sonography of the shoulder is widely used to assess various disorders, including tendinous diseases of the rotator cuff and the long head of the biceps brachii muscle. The shoulder is commonly explored through anterior, superior, and posterior approaches, but the inferior axillary approach is rarely considered in the literature. However, this technique allows the direct visualization of relevant anatomic structures. The aim of this pictorial essay is, first, to technically describe this approach and the normal musculoskeletal sonographic anatomy of the region and, second, to present the sonographic findings of shoulder disorders that may be helpfully explored this technique. PMID- 29575006 TI - First-in-man-proof of concept study with molidustat: a novel selective oral HIF prolyl hydroxylase inhibitor for the treatment of renal anaemia. AB - AIMS: Insufficient erythropoietin (EPO) synthesis is a relevant cause of renal anaemia in patients with chronic kidney disease. Molidustat, a selective hypoxia inducible factor prolyl hydroxylase (HIF-PH) inhibitor, increases endogenous EPO levels dose dependently in preclinical models. We examined the pharmacokinetics, safety, tolerability and effect on EPO levels of single oral doses of molidustat in healthy male volunteers. METHODS: This was a single-centre, randomized, single blind, placebo-controlled, group-comparison, dose-escalation study. Molidustat was administered at doses of 5, 12.5, 25, 37.5 or 50 mg as a polyethylene glycol based solution. RESULTS: In total, 45 volunteers received molidustat and 14 received placebo. Molidustat was absorbed rapidly, and the mean maximum plasma concentration and area under the concentration-time curve increased dose dependently. The mean terminal half-life was 4.64-10.40 h. A significant increase in endogenous EPO was observed following single oral doses of molidustat of 12.5 mg and above. Geometric mean peak EPO levels were 14.8 IU l-1 (90% confidence interval 13.0, 16.9) for volunteers who received placebo and 39.8 IU l-1 (90% confidence interval: 29.4, 53.8) for those who received molidustat 50 mg. The time course of EPO levels resembled the normal diurnal variation in EPO. Maximum EPO levels were observed approximately 12 h postdose and returned to baseline after approximately 24-48 h. All doses of molidustat were well tolerated and there were no significant changes in vital signs or laboratory safety parameters. CONCLUSIONS: Oral administration of molidustat to healthy volunteers elicited a dose-dependent increase in endogenous EPO. These results support the ongoing development of molidustat as a potential new treatment for patients with renal anaemia.

The anti-malarial 4-aminoquinoline compounds chloroquine and hydroxychloroquine are currently being considered for re purposing as anti-cancer therapies intended to sensitize different tumors by targeting the lysosomal cell death pathway. Here, we describe a novel organometallic chloroquine derivative, cymanquine, that exhibits enhanced bioactivity compared to chloroquine in both normal, and reduced pH tumor microenvironments, thus overcoming a defined limitation of traditional 4 aminoquinolines. In vitro, cymanquine exhibits greater potency than CQ in a diverse panel of human cancer cell lines, including melanoma, in both normal pH and in reduced pH conditions that mimic the tumor microenvironment. Cymanquine treatment results in greater lysosomal accumulation than chloroquine and induces lysosomal dysfunction leading to autophagy blockade. Using a mouse model of vemurafenib-resistant melanoma, cymanquine slowed tumor growth greater than hydroxychloroquine, and when used in combination with vemurafenib, cymanquine partially restored sensitivity to vemurafenib. Overall, we show that cymanquine exhibits superior lysosomal accumulation and autophagy blockade than either chloroquine or hydroxychloroquine in vitro; and in addition to its high level of tolerability in mice, exhibits superior in vivo efficacy in a model of human melanoma.

AB - Climate change can alter species interactions essential for maintaining biodiversity and ecosystem function, such as pollination. Understanding the interactive effects of multiple abiotic conditions on floral traits and pollinator visitation are important to anticipate the implications of climate change on pollinator services. Floral visual and olfactory traits were measured from individuals of four forb species subjected to drought or normal water availability, and elevated or ambient concentrations of CO2 in a factorial design. Pollinator visitation rates and community composition were observed in single-species and multi-species forb assemblages. Drought decreased floral visual traits and pollinator visitation rates but increased volatile organic compound (VOC) emissions, whereas elevated CO2 positively affected floral visual traits, VOC emissions and pollinator visitation rates. There was little evidence of interactive effects of drought and CO2 on floral traits and pollinator visitation. Interestingly, the effects of climate treatments on pollinator visitation depended on whether plants were in single- or multi-species assemblages. Components of climate change altered floral traits and pollinator visitation, but effects were modulated by plant community context. Investigating the response of floral traits, including VOCs, and context-dependency of pollinator attraction provides additional insights and may aid in understanding the overall effects of climate change on plant-pollinator interactions. PMID- 29575009 TI - The efficacy of fluoxetine in BMS-A cross-over study. AB - BACKGROUND: Burning mouth syndrome (BMS) is an intraoral burning or dysaesthetic sensation, recurring daily for more than two hours during the period longer than 3 months. The objective was to evaluate and analyse the efficacy of serotonin reuptake inhibitor fluoxetine on psychological factors, as well as on pain in participants with BMS. METHODS: In a 6-month study, 100 participants with primary and secondary BMS were divided into two groups-fluoxetine and control (placebo) and examined by the dentist and the neurologist. Depression and anxiety were estimated by Hamilton Scale for Depression (HAM-D) and Anxiety (HAM-A) and Beck Depression Inventory (BDI) and the pain intensity by visual analogue scale (VAS). RESULTS: Mean age of the participants was 60.33 in fluoxetine group and 67.4 in control group. Most of the participants were female-74% in the fluoxetine and 78% in the control group. Statistical difference between the fluoxetine and the control group was found in HAM-D results (P < .05). Values of other scales and VAS decreased significantly after the therapy in both groups (P < .05). CONCLUSIONS: Our trial results indicate that fluoxetine therapy not only improves the psychological status of participants with BMS but also fluoxetine decreases the intensity of pain in these patients. PMID- 29575010 TI - Impact of peer support on inpatient and outpatient payments among people with Type 2 diabetes: a prospective cohort study. AB - AIM: To investigate the impact of a low-cost diabetes peer-support intervention, aimed at reducing inpatient and outpatient care utilization and healthcare payments, by conducting a cohort study that followed up a randomized controlled trial. METHODS: A total of 1121 adults with Type 2 diabetes were recruited through general practices in Cambridgeshire and Hertfordshire, UK, and were followed up for 3.25 financial years after 8-12 months of one-to-one, group or combined diabetes peer support and usual care. Use of, and payments for inpatient and outpatient services were fully recorded in the follow-up. Adjusted mean inpatient and outpatient payments per person were estimated using a two-part model after adjusting for baseline characteristics. RESULTS: The mean age of the recruited adults was 65.6+/-11.4 years, 60.4% were male, and 16.8% were insulin treated. Compared with the control group, less healthcare utilization (especially non-elective inpatient care and outpatient consultations) was observed in each of the intervention groups, particularly the combined intervention group. Over the course of 3.25 financial years, significant reductions of 41% (L909.20 per head) were observed for overall inpatient payments (P<0.0001), 51% (L514.67 per head) for non-elective inpatient payments (P=0.005) in the combined intervention group, and 34% (L413.30 per head) and 32% (L388.99 per head) for elective inpatient payments in the one-to-one (P=0.029) and combined intervention (P=0.048) groups, respectively. CONCLUSIONS: Type 2 diabetes peer support, whether delivered using a one-to-one, group or combined approach was associated with reduced inpatient care utilization (particularly non-elective admissions) and payments over 3.25 years. PMID- 29575011 TI - Stroke localization and classification using microwave tomography with k-means clustering and support vector machine. AB - For any chance for stroke patients to survive, the stroke type should be classified to enable giving medication within a few hours of the onset of symptoms. In this paper, a microwave-based stroke localization and classification framework is proposed. It is based on microwave tomography, k-means clustering, and a support vector machine (SVM) method. The dielectric profile of the brain is first calculated using the Born iterative method, whereas the amplitude of the dielectric profile is then taken as the input to k-means clustering. The cluster is selected as the feature vector for constructing and testing the SVM. A database of MRI-derived realistic head phantoms at different signal-to-noise ratios is used in the classification procedure. The performance of the proposed framework is evaluated using the receiver operating characteristic (ROC) curve. The results based on a two-dimensional framework show that 88% classification accuracy, with a sensitivity of 91% and a specificity of 87%, can be achieved. Bioelectromagnetics. 39:312-324, 2018.

AB - Glutamate-ammonia ligase (GLUL), which is also called GS (glutamine synthetase), is the enzyme that catalyzes the synthesis of glutamine from glutamate and ammonia in an ATP-dependent reaction. Here, we found higher expression of GLUL in the ovarian cancer patients was associated with worse disease-free survival (DFS) and overall survival (OS). In addition, GLUL was heterogeneously expressed in various ovarian cancer cells. The mRNA and protein expression levels of GLUL in NIH:OVCAR-3 and ES-2 cells were obviously higher than that in the other types of ovarian cancer cells. Knockdown of GLUL in NIH:OVCAR-3 or ES-2 cells could significantly decrease the proliferation ability. Furthermore, GLUL knockdown markedly inhibited the p38 MAPK signaling pathway in NIH:OVCAR-3 or ES-2 cells. Our findings suggest that decreasing expression of GLUL may be a new approach that can be used for ovarian cancer treatment.

AB - Cervical cancer (CC) remains a highly prevalent cancer and mortality globally among women globally. The aim of the present study was to assess the ability of miR-374b to regulate CC cells through JAM-2, whilst exploring whether the underlying mechanism and its relation to the p38/ERK signaling pathway. During the study, microRNA-374b (miR-374b) was observed to have been expressed at a low level among CC tissues. Hence, a series of miR-374b mimics, miR-374b inhibitors, siRNA against JAM-2, SB202190 (an inhibitor for p38), and PD98059 (an inhibitor for ERK) were introduced to treat CC Siha cells and normal cervical Ect1/E6E7 cells. MTT, flow cytometry, scratch test, and transwell assays were applied to determine cell viability, apoptosis, migration, and invasion. The inhibitory role of the p38/ERK signaling pathway was observed in the CC cells treated with miR 374b mimics or siRNA against JAM-2. miR-374b mimic exposure was found to reduce cell viability, migration, and invasion, but induce apoptosis. MiR-374b inhibitor exposure was observed to have induced effects on the CC cells in a contrary manner to those induced by that of the miR-374b mimics. The key findings of the study demonstrated that miR-374b significantly inhibits cell proliferation, migration, and invasion through the blockade of the p38/ERK signaling pathway activation, as well as negatively binding to JAM-2, highlighting its potential as a therapeutic target for CC.

PMID- 29575015 TI - Duct-to-mucosa versus dunking techniques of pancreaticojejunostomy after pancreaticoduodenectomy: Do we need more trials? A systematic review and meta analysis with trial sequential analysis. AB - BACKGROUND: Pancreaticojejunostomy (PJ is the most widely used reconstruction technique after pancreaticoduodenectomy. Despite several randomized trials, the ideal technique of pancreaticojejunostomy remains debatable. We planned a meta analysis of randomized trials comparing the two most common techniques of PJ (duct-to-mucosa and dunking) to identify the best available evidence in the current literature. METHODS: We searched the Pubmed/Medline, Web of science, Science citation index, Google scholar and Cochrane Central Register of Controlled Trials electronic databases till October 2017 for all English language randomized trials comparing the two approaches. Statistical analysis was performed using Review Manager (RevMan), Version 5.3. Copenhagen: The Nordic Cochrane Center, The Cochrane Collaboration, 2014 and results were expressed as odds ratio for dichotomous and mean difference for continuous variables. P-value <= 0.05 was considered significant. Trial sequential analysis was performed using TSA version 0.9.5.5 (Copenhagen: The Copenhagen Trial Unit, Center for Clinical Intervention Research, 2016). RESULTS: A total of 8 trials were included, with a total of 1043 patients (DTM: 518; Dunking: 525). There was no significant difference between the two groups in terms of overall as well as clinically relevant POPF rate. Similarly, both groups were comparable for the secondary outcomes. Trial sequential analysis revealed that the required information size had been crossed without achieving a clinically significant difference for overall POPF; and though the required information size had not been achieved for CR-POPF, the current data has already crossed the futility line for CR-POPF with a 10% risk difference, 80% power and 5% alpha error. CONCLUSION: This meta analysis found no significant difference between the two techniques in terms of overall and CR-POPF rates. Further, the existing evidence is sufficient to conclude lack of difference and further trials are unlikely to result in any change in the outcome. (CRD42017074886). PMID- 29575016 TI - Simultaneous determination of twelve polar pteridines including dihydro- and tetrahydropteridine in human urine by hydrophilic interaction liquid chromatography with tandem mass spectrometry. AB - Pteridines and their derivatives are important cofactors in the process of cell metabolism, and the level of urinary excretion of these compounds is considered as an important clinical criterion. In this work, a new separation method involving hydrophilic interaction chromatography (HILIC) with tandem mass spectrometric detection has been developed for the simultaneous analysis of 12 pteridines including oxidized, di- and tetrahydroforms, namely neopterin, 7,8 dihydroneopterin, biopterin, 7,8-dihydrobiopterin, 5,6,7,8-tetrahydrobiopterin, dimethylpterin, dimethyltetrahydropterin, pterin, isoxanthopterin, xanthopterin, sepiapterin and pterin-6-carboxylic acid, in human urine without oxidative pretreatments. The stabilizing agent (dithiothreitol) at various concentrations and the stability of oxidized, di- and tetrahydroforms during the sample's short term storage and processing and of the extracts were tested. In the developed method, 12 pteridines were chromatographically separated on an ZIC-HILIC column by gradient elution, and the run time was 20 min. Matrix effect was evaluated and several dilutions of urine were tested in order to study the evolution of signal suppression. Spiked recovery studies demonstrated that the technique was both accurate (83.1-116.7%) and precise (RSD 1.4-15.6%). Finally, several clinical urine specimens without oxidative pretreatments were examined with the new technique and compared with previous reports. PMID- 29575018 TI - The Diversification of Early Emerging Metazoans: A Window into the Evolution of Animal Multicellularity. AB - The biannual international workshop entitled "The diversification of early emerging metazoans: A window into animal evolution?" took place at the Evangelische Akademie Tutzing, Germany, 11-14. September 2017. It was organized by Thomas Bosch (Kiel), Thomas Holstein (Heidelberg), and Ulrich Technau (Vienna), and it was sponsored by the Deutsche Forschungsgemeinschaft (DFG). The meeting gathered over 140 researchers to discuss the contribution of non bilaterian metazoan models (Porifera, Ctenophora, Placozoa, and Cnidaria) to our understanding of: a. The evolution of metazoan developmental processes; b. Fundamental molecular mechanisms underlying metazoan features; and c. The complex interactions that animals establish with their environment. PMID- 29575017 TI - An update on the clinical evidence that supports biosimilar approvals in Europe. AB - AIM: Sponsors and regulators have more than 10 years of experience with the development of biosimilars in Europe. However, the regulatory pathway is still evolving. The present article provides an update on biosimilar development in practice by reviewing the clinical development programmes of recently approved biosimilars in Europe. METHODS: We used the European public assessment reports (EPARs) which are published by the European Medicines Agency (EMA) for a comparison of the clinical development programmes of the 37 approved biosimilars in Europe. Here, we present novel strategies in the development of biosimilars by focusing specifically on the 17 biosimilars that have gained approval in the last year, but we also compare additional key characteristics for all approved biosimilars. RESULTS: The high variability of the clinical development strategies that we found previously was confirmed in the present analysis. Compared with earlier biosimilar applications, more nonstandard development strategies have been used recently. This includes, for example, applications without any studies in patients, and more complex study designs. During this study, we found that the EPARs for biosimilars seem to be improving; however, we identified important details which were still often missing. We provide a proposal for a checklist of the minimum information that should be included in biosimilar EPARs for giving the general public insights into the rationale for the approval of biosimilars. CONCLUSIONS: European regulators still seem to be open to consider approaches that differ from the guidelines or previous applications, as long as justification is provided. PMID- 29575019 TI - Reduced vision, refractive errors and health-related quality of life among adolescents in rural China. AB - BACKGROUND: To determine the associations of reduced presenting visual acuity (VA), refractive errors and health-related quality of life (HRQoL) in healthy adolescents in rural China. METHODS: A total of 2,235 grade 7 students without systemic medical problems from 10 middle schools aged 13-14 years in Mojiang, a small county located in southwestern China, were included in the analysis. Reduced VA was defined as presenting VA of worse than 6/12 in the presence of an ophthalmic aetiology which could be identified. The refractive status of each participant was measured after cycloplegia using an autorefractor. The Pediatric Quality of Life Inventory Version 4.0 Generic Core Scales was used for measuring HRQoL of the participants. RESULTS: Among all the participants included in the data analysis, 279 (12.5 per cent) individuals were affected by reduced VA based on the better-seeing eye data. After adjusting for the effect of gender, body mass index, the education level of the father, and the use of a corrective device, the total (adjusted mean difference: -3.27; 95 per cent confidence interval [CI] -4.95 to -1.59; p = 0.01), social functioning (adjusted mean difference: -3.44; 95 per cent CI -5.87 to -1.01; p = 0.02) and school functioning scores (adjusted mean difference: -3.12; 95 per cent CI -5.89 to 0.35; p = 0.04) of the adolescents with reduced presenting VA were significantly lower compared with those with normal vision. The associations between corrected refractive errors and HRQoL were not significant. CONCLUSIONS: Healthy adolescents with reduced VA reported lower HRQoL scores including total, social functioning and school functioning scores, compared with those with normal vision. PMID- 29575020 TI - The VFH1 (YLL056C) promoter is vanillin-inducible and enables mRNA translation despite pronounced translation repression caused by severe vanillin stress in Saccharomyces cerevisiae. AB - Vanillin, furfural and 5-hydroxymethylfurfural (HMF) are representative fermentation inhibitors generated during the pretreatment process of lignocellulosic biomass in bioethanol production. These biomass conversion inhibitors, particularly vanillin, are known to repress translation activity in Saccharomyces cerevisiae. We have reported that the mRNAs of ADH7 and BDH2 were efficiently translated under severe vanillin stress despite marked repression of overall protein synthesis. In this study, we found that expression of VFH1 (YLL056C) was also significantly induced at the protein level by severe vanillin stress. Additionally, we demonstrated that the VFH1 promoter enabled the protein synthesis of other genes including GFP and ALD6 under severe vanillin stress. It is known that transcriptional activation of VFH1 is induced by furfural and HMF, and we verified that Vfh1 protein synthesis was also induced by furfural and HMF. The null mutant of VFH1 delayed growth in the presence of vanillin, furfural and HMF, indicating the importance of Vfh1 for sufficient tolerance against these inhibitors. The protein levels of Vfh1 induced by the inhibitors tested were markedly higher than those of Adh7 and Bdh2, suggesting the superior utility of the VFH1 promoter over the ADH7 or BDH2 promoter for breeding optimized yeast strains for bioethanol production from lignocellulosic biomass.

PMID- 29575022 TI - Prevalence and sonographic features of ectopic thyroidal thymus in children: A retrospective analysis. AB - PURPOSE: To assess the prevalence of ectopic thyroidal thymus tissue detected by sonography (US) in children and to analyze the US features. METHODS: We retrospectively reviewed images of 216 children who had undergone a thyroid or neck US examination from February 2015 to June 2015. Lesions within or adjacent to the thyroid gland that showed echopatterns consistent with thymic tissue were diagnosed as ectopic thyroidal thymus tissue. Lesions were reviewed according to their side, location, level, size, shape, echo pattern, internal content, and vascularization. RESULTS: A total of 216 children (119 girls, 97 boys) with a mean +/- SD age of 8.6 +/- 5.2 years were enrolled the study.Thirty children (13girls, 17 boys) (13.9%) had 35 lesions compatible with ectopic thyroidal thymus tissue.Nine children had intrathyroidal (4.2%) and 21 children had extrathyroidal (9.7%) ectopic thymus tissue.The mean +/- SD ages of the children with and without ectopic thyroidal thymus tissue were 6.0 +/- 3.6 years and 9.1 +/- 5.2 years, respectively (P = .002). Twenty-five of the lesions were extrathyroidal and 10 were intrathyroidal. All extrathyroidal and most (8/9) intrathyroidal ectopic thymuses had fusiform shape with well demarcated contours. Ectopic thymuses were located either in the midportion (n = 23) or lower portion of the neck (n = 12). Both extrathyroidal and intrathyroidal ectopic thymuses showed typical hypoechoic (n = 22/25, n = 9/10, respectively) or hyperechoic (n = 3/25, n = 1/10, respectively) echo patterns with internal linear and punctate echoes. CONCLUSIONS: Ectopic thyroidal thymic tissue is common in children. Radiologists should be vigilant about the unique US features of ectopic thyroidal thymus, including a hypo- and hyper-echoic echo pattern with multiple linear and punctate echoes, a fusiform shape, well-demarcated contours, and middle or low lying location to differentiate it from other neck or thyroid lesions. PMID- 29575023 TI - Progression and new onset of nonalcoholic fatty liver disease in living kidney donors compared to healthy controls. AB - BACKGROUND: There is growing evidence linking nonalcoholic fatty liver disease (NAFLD) with reduced glomerular filtration rate (GFR). Living kidney donors do not have underlying kidney disease, but have reduced GFR as a result of nephrectomy. Whether kidney donation is associated with a higher risk for development or progression of NAFLD is currently unknown. METHODS: Retrospective evaluation of metabolic parameters and sonographic evidence of NAFLD were performed in 232 living kidney donors and 162 healthy controls. RESULTS: A total of 25 donors and 44 controls had NAFLD at baseline. During a mean follow-up of 6.8 years, 6 donors (24%) and 17 controls (38.6%) (P = .29) had a remission of NAFLD, related with decreased body mass index (BMI). The progression of NAFLD fibrosis score was similar in both groups. New onset of NAFLD was observed in 14 (6.8%) donors and 13 (11.01%) controls (P = .211), and was related to increased BMI and a higher baseline Fatty Liver Index score. Neither eGFR nor urine albumin excretion in the donors were related to new onset or progression of NAFLD. CONCLUSIONS: Reduced kidney function secondary to kidney donation is not associated with increased incidence or progression of NAFLD. PMID- 29575024 TI - Toxicity of silver nanoparticles to Lumbriculus variegatus is a function of dissolved silver and promoted by low sediment pH. AB - Toxicity of silver nanoparticles (AgNPs) to benthic organisms is a major concern. The use of AgNPs in industry and consumer products leads to increasing release of AgNPs into the aquatic environment-sediments being the major sink. Effects of sediment pH on the toxicity of AgNPs to benthic oligochaeta Lumbriculus variegatus were studied in a 23-d toxicity test. Artificially prepared sediments (pH 5 and 7) were spiked with varying concentrations of uncoated AgNP, polyvinylpyrrolidone (PVP)-coated AgNP, and silver nitrate (AgNO3 ) as dissolved Ag reference. Number of individuals and biomass change were used as endpoints for the toxicity. The toxic effects were related to the bioaccessible concentration of dissolved Ag in the sediments, assessed with a 2-step extraction procedure. The toxicity of 2 AgNPs was similar and greatly enhanced in the acidic sediment. Because the toxic effects were well related to the bioaccessible concentration of dissolved Ag in the sediments, the toxicity of sediment-associated AgNPs to L. variegatus is suggested to be a function of dissolved Ag rather than a result from NP-specific modes of toxicity.

AB - OBJECTIVE: To assess long-term clinical and radiological outcomes of surgical treatment of peri-implantitis. MATERIAL AND METHODS: Files and radiographs from 50 patients who had received surgical treatment for peri-implantitis were analyzed. Data on clinical characteristics prior to surgical therapy and at latest follow-up were obtained. In each radiograph, the marginal bone level was assessed at the mesial and distal aspects of the affected implants. The treatment included oral hygiene instruction, professional supra-mucosal instrumentation, and surgical therapy aiming at pocket elimination. Following flap elevation and removal of inflamed tissue, the affected implant was cleaned using gauze soaked in saline. Calculus was removed. When indicated, osseous re-contouring was carried out to facilitate pocket elimination. Flaps were adjusted, sutured, and compressed to the crestal bone. Supportive therapy including oral hygiene control was provided with 4-month intervals. RESULTS: Treatment was effective in resolving the inflammatory condition as documented by marked reduction in peri implant probing depth and bleeding on probing scores together with crestal bone level preservation. Treatment outcome was significantly better at implants with non-modified surfaces than at implants with modified surfaces. The probability of an implant to exhibit no further bone loss or bone gain after treatment was high if the peri-implant mucosa at the site presented with shallow pockets and the absence of bleeding on probing at follow-up. CONCLUSIONS: The results of the study revealed that (i) surgical treatment of peri-implantitis was effective in the long-term, (ii) outcome was better at implants with non-modified than with modified surfaces, and (iii) preservation of crestal bone support was consistent with healthy peri-implant tissue conditions. PMID- 29575026 TI - AG-1031 induced autophagic cell death and apoptosis in C6 glioma cells associated with Notch-1 signaling pathway. AB - Glioma is the most common primary brain tumor with high morbidity and poor prognosis. The effect of AG-1031, which is developed as an antineoplastic drug, on C6 glioma cells is still not clear. The aim of this research was to explore the effect of AG-1031 on C6 cells, and tried to find out its potential mechanism on cytotoxicity of C6 cells. The 3-(4,5-dimethylthiazol -2-yl) -2,5- diphenyltetrazolium bromide (MTT) assay showed that AG-1031 inhibited cell viability in a concentration-dependent manner, whereas 3-methyadenine (3-MA) reduced this effect. Results from hoechst 33342 staining and Western blot assay indicated that AG-1031 induced C6 cell apoptosis. Western blot assay presented that AG-1031 notably increased the LC3-II/LC3-I ratio and decreased the expression of P62. Besides, our results showed that bafilomycin A1 increased the expression of LC3-II in cells treated with AG-1031, which indicated that AG-1031 can increase autophagy in C6 cells. Meanwhile, Western blot assay showed that AG 1031 can inhibit Notch-1 signaling by testing relative protein expressions. The expression of the intracellular domain of Notch (NICD) also decreased according to immunofluorescence assay. Additionally, the activation of Notch-1 signaling alleviated AG-1031-induced autophagic cell death and apoptosis. Furthermore, phosphorylated Akt and its downstream effector mechanistic target of rapamycin (mTOR) were reduced with AG-1031. These results suggest that AG-1031 may induce autophagic cell death through the inhibition of Akt-mTOR signaling pathway by down-regulating Notch-1 signaling pathway and activating apoptosis in C6 cells via Notch-1 signaling, which develops a new target spot to treat glioma in the future.

AB - Ultrasound (US) plays a critical role in the evaluation, treatment, screening, and surveillance of thyroid malignancy in pediatric patients. This review aims to summarize recent advances in this topic. Improvements in imaging technology have amplified the advantage of US and US-guided fine-needle aspiration biopsy for thyroid nodule evaluation, cancer diagnosis, and surgical planning. Ultrasound has a definitive screening role for early cancer detection in high-risk patients, including those with a history of radiation exposure from childhood treatments, environmental radiation disasters, or hereditary/familial cancer syndromes. Finally, US is a key component of lifelong surveillance for recurrence among pediatric thyroid cancer survivors. PMID- 29575029 TI - A Practical Approach to Quantitative Grayscale Ultrasound Analysis of Hepatic Steatosis in Pediatric Patients Using a Picture Archiving and Communication System-Based Tool. AB - OBJECTIVES: To evaluate the efficacy of a picture archiving and communication system (PACS)-based ultrasound (US) quantification technique for diagnosis of hepatic steatosis in a pediatric population. METHODS: Abdominal US images of 49 pediatric patients (<=18 years) with histopathologically proven diagnoses of hepatic steatosis (n = 17), nonsteatotic liver disease (n = 19), and a normal liver (n = 13) were retrospectively reviewed. Patient demographics, the fibrosis stage, and the steatosis grade were obtained from the database. Quantitative grayscale measurements of the echo intensity level of the liver and kidneys were performed on the US images using the PACS measuring tool. The hepatorenal ratio was obtained by dividing mean liver by mean kidney values. The heterogeneity index for the liver was calculated by dividing the liver standard deviation by mean liver values. Hepatorenal ratio and heterogeneity index values of the 3 groups were correlated with pathologic results and compared by a 1-way analysis of variance. A receiver operating characteristic curve analysis was performed, and cutoff values were determined. RESULTS: The hepatorenal ratio of the hepatic steatosis group was significantly greater than those of the control and nonsteatotic liver disease groups (P < .001). The heterogeneity index of the hepatic steatosis group was significantly greater than that of the control group (P = .046). For a hepatorenal ratio cutoff value of 1.5, 88.2% sensitivity, 91.4% specificity, 88.3% positive predictive value, and 94.1% negative predictive value were obtained for predicting hepatic steatosis. CONCLUSIONS: PACS-based quantitative grayscale US quantification is a safe, accurate, and easily applicable objective method for the diagnosis of hepatic steatosis in children. A hepatorenal ratio of greater than 1.5 can be used as a conservative parameter, permitting increased confidence in discriminating hepatic steatosis from other conditions. PMID- 29575030 TI - Shifts in gut microbiota composition in an APP/PSS1 transgenic mouse model of Alzheimer's disease during lifespan. AB - : Alzheimer's disease (AD) is the most common form of dementia and one of the major causes of disability and dependency in older people. Accumulating evidences link gut microbiota with different diseases and its relationship with neurodegenerative diseases is becoming most intriguing. This study was aimed to compare the gut microbiota of transgenic APP/PS1 (TG) mice, a well-established deterministic mouse model of AD, with their C57BL/6 wild-type (WT) littermates. Faecal samples were collected from 3-, 6- and 24-month-old mice and analysed by pyrosequencing of the V1-V3 region of the bacterial 16S rRNA genes. Bacterial profiles were similar in all young mice (3 months old), and started to diverge so that 6-month-old WT and TG mice had different and more diverse microbiota. During ageing, Turicibacteriaceae (typical mice bacterial group) and Rikenellaceae increased in all groups, although total Bacteroidetes remained stable. TG mice were characterized by an increase in Proteobacteria after 6 months, particularly the genus Sutterella (Betaproteobacteria), interestingly also increased in autism disorder. Also, the inflammation related family Erysipelotrichaceae was more abundant in TG mice at 24 months compared to wild-type control. In summary, AD pathology in mice shifts the gut microbiota towards profiles that share features with autism and inflammatory disorders. SIGNIFICANCE AND IMPACT OF THE STUDY: Alzheimer's disease is a neurodegenerative disease and neuroinflammation in the central nervous system appears to have a pivotal role. Using the transgenic APP/PS1 (TG) mouse model, we successfully characterized how AD pathology shifted gut microbiota composition during ageing towards an inflammation related bacterial profile related to Proteobacteria and Erysipelotrichaceae and suggest that these changes could contribute to disease progression and severity. Microbiota-targeted interventions could therefore represent a strategy to postpone disease symptoms.

PMID- 29575031 TI - Parenting style impacts cognitive and behavioural outcomes of former preterm infants: A systematic review. AB - We sought to evaluate published evidence in aggregate regarding the impact of parenting style on the cognitive and behavioural outcomes of former preterm infants. We searched 5 databases using germane MeSH terms. Parenting style was defined as any descriptor of parenting using >=2 dimensions on published parenting axes. We evaluated studies for quality of evidence and strength of recommendations using standardized tools and categorized summative recommendations by parenting axis and child outcome. Twenty-seven articles met our inclusion criteria. Parental responsivity is the only parenting axis strongly associated with both improved child cognition and behaviour. Parental demandingness is associated only with improved child cognition, and parental warmth and rejection are associated only with child behaviour. Parental coercion is not associated with subsequent child outcomes. Parental responsivity may be essential in optimizing neurodevelopment in former preterm infants. More targeted studies are needed to inform this relationship and identify opportunities for intervention. PMID- 29575034 TI - Accommodative accuracy by retinoscopy versus autorefraction spherical equivalent or horizontal meridian power. AB - BACKGROUND: To assess agreement between accommodative lag by monocular estimation method (MEM) retinoscopy and Nott retinoscopy compared to open-field autorefraction using spherical equivalent versus power in the 180 meridian for both children and adults. METHODS: Twenty-six children aged 7-16 years (mean: 9.9 +/- 2.3) and 27 adults aged 22-29 years (mean: 24.2 +/- 1.7) participated. Accommodative lag was measured by examiners with autorefraction and separate examiners using MEM and Nott retinoscopy while subjects viewed 6/18 letters at 33 cm. Five measures of autorefraction were averaged with vector analysis and both power in the 180 meridian and spherical equivalent was determined. Two-factor repeated measures analysis of variance and the mean difference and 95 per cent limits of agreement were calculated. RESULTS: Mean (standard deviation) lag for each technique was: MEM = 0.69 (0.52) D, Nott = 0.62 (0.51) D, autorefraction in 180 = 0.66 (0.50) D and autorefraction spherical equivalent = 0.60 (0.46) D. Lag did not vary across techniques (p = 0.48), but children did have smaller lags than adults (p < 0.001) and greater amounts of uncorrected astigmatism (0.61 +/- 0.09 D versus 0.42 +/- 0.08 D, p = 0.02). There was no significant interaction between age group and technique (p = 0.74). Mean differences between techniques were small, ranging from -0.14 to +0.06 D. Ninety-five per cent limits of agreement ranged from +/-0.80 to +/-1.33 around the mean with the narrowest ranges found for comparisons made to autorefraction in 180. Limits of agreement were also narrowest in children as compared to adults with similar mean differences between age groups. CONCLUSIONS: This study demonstrates the mean agreement between autorefraction and retinoscopic techniques is centred on zero (no bias) in both children and adults. The range of agreement becomes narrower when autorefraction power in the 180 is calculated, even for a sample of subjects with moderately small amounts of uncorrected astigmatism.

AB - OBJECTIVE: To investigate whether early neurochemical abnormalities are detectable by high-field magnetic resonance spectroscopy (MRS) in individuals with spinocerebellar ataxias (SCAs) 1, 2, 3, and 6, including patients without manifestation of ataxia. METHODS: A cohort of 100 subjects (N = 18-21 in each SCA group, including premanifest mutation carriers; mean score on the Scale for the Assessment and Rating of Ataxia [SARA] <10 for all genotypes, and 22 matched controls) was scanned at 7 Tesla to obtain neurochemical profiles of the cerebellum and brainstem. A novel multivariate approach (distance-weighted discrimination) was used to combine regional profiles into an "MRS score." RESULTS: MRS scores robustly distinguished individuals with SCA from controls, with misclassification rates of 0% (SCA2), 2% (SCA3), 5% (SCA1), and 17% (SCA6). Premanifest mutation carriers with estimated disease onset within 10 years had MRS scores in the range of early-manifest SCA subjects. Levels of neuronal and glial markers significantly correlated with SARA and an Activities of Daily Living score in subjects with SCA. Regional neurochemical alterations were different between SCAs at comparable disease severity, with SCA2 displaying the most extensive neurochemical abnormalities, followed by SCA1, SCA3, and SCA6. INTERPRETATION: Neurochemical abnormalities are detectable in individuals before manifest disease, which may allow premanifest enrollment in future SCA trials. Correlations with ataxia and quality-of-life scores show that neurochemical levels can serve as clinically meaningful endpoints in trials. Ranking of SCA types by degree of neurochemical abnormalities indicates that the neurochemistry may reflect synaptic function or density. Ann Neurol 2018;83:816-829. PMID- 29575035 TI - MicroRNA expression profiles of neural stem cells following valproate inducement. AB - Neural stem cells (NSCs) possess self-renewal and multilineage differentiation ability, thus are considered to be a potential source for cell replacement therapy of many nervous system diseases, such as neurodegenerative diseases. Valproate (VPA), a member of histone deacetylase inhibitor family, is an epigenetic regulator and can promote NSCs to differentiate into neurons, nevertheless, the underlying mechanisms of the process remain unclear. MicroRNAs (miRNAs) exert a crucial part in the posttranscriptional regulation of gene expression. Epigenetic mechanisms involve in the regulation of miRNAs expression. Therefore we speculated that miRNAs may be important factors during the promotion of neuronal differentiation by VPA. Here, after selecting appropriate concentration and treatment time of VPA, we conducted microRNA arrays at 24 h on the treatment of 1 mM VPA or vehicle. After validation, we obtained 5 significantly upregulated miRNAs (miR-29a-5p, miR-674-5p, miR-155-5p, miR-652-3p, and miR-210-3p) in VPA group compared with control. We predicted the target genes of these miRNAs on the website. Through gene ontology (GO) and pathway analyses, we obtained preliminary comprehension of the function of these genes. The bioinformatics analyses indicated the involvement of them during neurogenesis. In addition, we observed high expression of miR-210-3p, miR-29a-5p, and miR-674-5p in central nervous system, which suggested that they were likely to play crucial roles in neuronal differentiation. We then defined the upregulation of Map2 by transfecting mimic of miR-674-5p, which indicated the promotion of miR-674-5p on NSCs differentiation. The present study explored the miRNAs potentially mediated the function of VPA on promoting NSCs to differentiate into neurons. PMID- 29575036 TI - The psychological distress and care needs of mesothelioma patients and asbestos exposed subjects: A systematic review of published studies. AB - BACKGROUND: The purpose of this study is to present the results of a systematic review of published research that focuses on psychological aspects of malignant mesothelioma patients and asbestos-exposed people. METHODS: Our research includes primary studies published between 1980 and 2016, using information from the Cochrane Library, the Psychology Behavioral Sciences Collection, PsychINFO, PubMed, PubGet, PubPsych, and Scopus, in compliance with PRISMA guidelines. RESULTS: We identified 12 papers that investigated the psychological distress and care needs of mesothelioma patients, and nine papers for asbestos-exposed subjects. CONCLUSIONS: This paper highlights the paucity of studies on the psychological distress and care needs of mesothelioma patients and asbestos exposed subjects. It confirms that malignant mesothelioma is associated with the physical, emotional, and social functioning of patients, while also suggesting that the risk of developing asbestos-related diseases among asbestos-exposed subjects is associated with high levels of psychological distress, despair, and mental health difficulties. PMID- 29575037 TI - Mechanical bacterial lysate administration prevents exacerbation in allergic asthmatic children-The EOLIA study. AB - BACKGROUND: Despite progress in asthma management, prevention of asthma exacerbation remains challenging in school-aged children with allergic asthma. New therapeutic approaches are needed. Previously, a chemical bacterial lysate has been successfully used in preschool children to reduce wheezing attacks. We assessed the effect of Polyvalent Mechanical Bacterial Lysate (PMBL(r) ) Tablet on asthma clinical course and control in 6- to 16-year-old children with partly controlled or uncontrolled allergic asthma. METHODS: A randomized, double-blind, placebo-controlled, parallel-group study was performed in 152 patients exhibiting allergic asthma assigned to receive Placebo or PMBL(r) . Eligible patients underwent four visits during the 9-month study. Asthma control level was assessed by ACT/C-ACT score. RESULTS: The main criterion was not achieved as ACT/C-ACT changes were similar in both groups at the end of the 3-month treatment period. However, the mean number (+/-SD) of asthma exacerbations was significantly lower with PMBL(r) Tablet than with Placebo at Week 12 (0.3 +/- 0.6 vs 0.8 +/- 1.1, P = .009) and over the total study period (1.1 +/- 1.3 vs 1.9 +/- 2.0, P = .01). Consistently, the mean number of days with exacerbation per patient was significantly lower with PMBL(r) Tablet (13.3 +/- 11.2 vs 19.8 +/- 15.7 over the whole study, P = .009). Treatment with PMBL(r) Tablet prolonged the time to second exacerbation by 55% (Hazard Ratio [HR]=0.45; 95% Confidence Interval [CI] 0.27 to 0.77, P = .002) and to third exacerbation by 74% (HR=0.26; 95% CI 0.12 to 0.58, P < .001). No serious adverse event related to PMBL(r) Tablet administration was recorded. CONCLUSION: Administration of PMBL(r) Tablet represents a safe and effective means for significantly reducing the rate of exacerbations in school-aged allergic asthmatic children.

AB - PURPOSE: To investigate the impact of hospital volume on short-term outcomes after cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC). METHODS: We identified mRCC patients who underwent CN from 2006 to 2013 in the National Cancer Database. Annual hospital CN volume was categorized as high (top 20th percentile) and low. Multivariable logistic regressions were used to compare 30-day mortality, 90-day mortality, prolonged length of stay (PLOS, >=7 days), and 30-day readmission rates. Sensitivity analyses were performed with hospital volume considered as a continuous variable. RESULTS: A total of 9789 patients were included with high-volume (n = 1916) defined as >=8 cases and low-volume (n = 7873) as 1-7 cases annually. Multivariable logistic regression showed that high volume was associated with lower odds of 30-day mortality (OR = 0.69, P = 0.013), 90-day mortality (OR = 0.65, P < 0.001), PLOS (OR = 0.82, P = 0.002), and 30-day readmission (OR = 0.78, P = 0.028). Sensitivity analyses showed that increasing hospital volume (per case) was associated with lower odds of 30-day mortality (OR = 0.965, P = 0.008), 90-day mortality (OR = 0.966, P < 0.001), PLOS (OR = 0.982, P = 0.001), and 30-day readmission (OR = 0.975, P = 0.012). CONCLUSION: Higher hospital volume was associated with better short-term outcomes after CN. Future studies are needed to validate our findings and explore the potential components leading to better outcomes in the higher volume hospitals. PMID- 29575039 TI - Alopecia areata treated with hydroxychloroquine: A retrospective study of nine pediatric cases. AB - BACKGROUND/OBJECTIVES: Alopecia areata is a common hair loss condition that is often emotionally devastating for patients. There is a paucity of effective treatments available. Hydroxychloroquine has been reported as variably effective in inducing significant hair regrowth in adults with alopecia areata. The objective of this retrospective study was to assess the benefit and tolerability of hydroxychloroquine in pediatric alopecia areata. METHODS: We conducted a retrospective review of nine children with a history of alopecia areata treated with hydroxychloroquine. Clinical data were obtained from patients treated at two tertiary care centers in the United States between July 1, 2013, and July 1, 2015. RESULTS: Alopecia scores of five patients improved by 6 months of treatment. Four patients experienced no improvement from baseline evaluation. The most common side effect associated with treatment was gastrointestinal intolerance and headache. CONCLUSION: This retrospective series suggests that hydroxychloroquine can be considered as a treatment option for alopecia areata in children. PMID- 29575041 TI - Remembering Jim Melius. PMID- 29575040 TI - Changes in the mitochondrial proteome of developing maize seed embryos. AB - Mitochondria are required for seed development, but little information is available about their function and role during this process. We isolated the mitochondria from developing maize (Zea mays L. cv. Nongda 108) embryos and investigated the mitochondrial membrane integrity and respiration as well as the mitochondrial proteome using two proteomic methods, the two-dimensional gel electrophoresis (2-DE) and sequential windowed acquisition of all theoretical fragment ion mass spectra (SWATH). Mitochondrial membrane integrity and respiration were maintained at a high level up to 21 days after pollination (DAP) and decreased thereafter, while total mitochondrial number, cytochrome c oxidase activity and respiration per embryo exhibited a bell-shaped change with peaks at 35-45 DAP. A total of 286 mitochondrial proteins changed in abundance during embryo development. During early stages of seed development (up to 21 DAP), proteins involved in energy production, basic metabolism, protein import and folding as well as removal of reactive oxygen species dominated, while during mid or late stages (35-70 DAP), some stress- and detoxification-related proteins increased in abundance. Our study, for the first time, depicted a relatively comprehensive map of energy production by mitochondria during embryo development. The results revealed that mitochondria were very active during the early stages of maize embryo development, while at the late stages of development, the mitochondria became more quiescent, but well-protected, presumably to ensure that the embryo passes through maturation, drying and long-term storage. These results advance our understanding of seed development at the organelle level. PMID- 29575042 TI - Monitoring Morphologic Changes in Male Rowers Using Limited Portable Echocardiography Performed by a Frontline Physician. AB - Athletes' hearts have been studied for adaptive changes in response to exercise. Physiologic changes are normal responses to intense athletic training regimens, whereas pathologic changes predispose athletes to sudden cardiac death. The two alterations overlap in clinical presentation. Research continues to investigate the upper limits of cardiac remodeling to aid clinical decision making. Studying normal changes that occur in response to exercise will advance physicians' understanding of physiologic responses to exercise and potentially improve clinical distinction. To expand this body of knowledge, we present an observational case series that describes morphologic changes in athlete's hearts concurrent with performance measurements. PMID- 29575043 TI - Preventing family transmission of anxiety: Feasibility RCT of a brief intervention for parents. AB - OBJECTIVES: Children of anxious parents are at high risk of anxiety disorders themselves. The evidence suggests that this is due to environmental rather than genetic factors. However, we currently do little to reduce this risk of transmission. There is evidence that supporting parenting in those with mental health difficulties can ameliorate this risk. Therefore, the objective of this study was to test the feasibility of a new one-session, group-based, preventive parenting intervention for parents with anxiety disorders. DESIGN: Feasibility Randomized Controlled Trial. METHODS: A total of 100 parents with anxiety disorders, recruited from adult mental health services in England (and child aged 3-9 years), were randomized to receive the new intervention (a 1-day, group workshop), or to treatment as usual. Children's anxiety disorder and anxiety symptoms were assessed to 12 months by outcome assessors who were blind to group allocation. Exploratory analyses were conducted on an intention to treat basis, as far as possible. RESULTS: A total of 51 participants were randomized to the intervention condition and 49 to the control condition (82% and 80% followed to 12 months, respectively). The attendance rate was 59%, and the intervention was highly acceptable to parents who received it. The RCT was feasible, and 12-month follow-up attrition rates were low. Children whose parents were in the control condition were 16.5% more likely to have an anxiety disorder at follow-up than those in the intervention group. No adverse events were reported. CONCLUSIONS: An inexpensive, light-touch, psycho-educational intervention may be useful in breaking the intergenerational cycle of transmission of anxiety disorders. A substantive trial is warranted. PRACTITIONER POINTS: Anxiety disorders run in families, but we currently do little to help anxious parents to raise confident children. A brief group workshop was highly acceptable to such parents and was very inexpensive to run. Children of parents who took part in the brief intervention were 16.5% less likely to have an anxiety disorder, 1 year later, than children whose parents were in the control group. This was a feasibility study, and while it showed that both the intervention and the research were feasible, the study needs replicating with a much larger sample. Many parents faced barriers to attending the workshop, and future efforts should focus on widening accessibility. We were unable to obtain sufficient self-report data from children, so the outcomes are based on parent report only. PMID- 29575044 TI - Correlation between neutrophil/lymphocyte ratio and Ranson score in acute pancreatitis. AB - BACKGROUND: Acute pancreatitis (AP) is characterized by inflammation of the pancreas, elevated pancreatic enzymes, and abdominal pain. The neutrophil to lymphocyte ratio (NLR) is used as a marker of inflammation. In this retrospective study, we aimed to investigate novel early prognostic predictors of AP, such as NLR and its correlation with the Ranson score. METHODS: A total 435 patients (Male: 152; 34.9%, Age: 63.53 +/- 17.22 years) were included in the study. Data were collected by two clinicians scanning the registered hospital records. RESULTS: Classification of the patients according to the aetiologies revealed gallstone(s) 58.6% (n = 255), hyperlipidaemia 2.2% (n = 9), viruses 0.7% (n = 3), malignancies 0.5% (n = 2), and alcohol 0.2% (n = 1). No reason was discovered in 37.9% (n = 165) of patients. Age, duration in the intensive care unit, serum aspartate aminotransferase (AST) levels, alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin, direct bilirubin, lactate dehydrogenase (LDH), white blood cell (WBC) count, neutrophil count, lymphocyte count, and the NLR were greater in the group with a Ranson score >=3 than the group with a Ranson score <3. DISCUSSION: Quick diagnosis is essential in AP. Current scoring systems for AP diagnosis are complicated, whereas NLP is a simple, practical, and effective marker.

AB - A series of (R,S)-1-{[5-(substituted)sulfanyl-4-substituted-4H-1,2,4-triazole-3 yl]methyl}-1,8-diethyl-1,3,4,9-tetrahydropyrano[3,4-b]indoles (5a-v) were designed and synthesized using a five-step synthetic protocol that involves substituted benzyl chlorides and (R,S)-5-[(1,8-diethyl-1,3,4,9 tetrahydropyrano[3,4-b]indole-1-yl)methyl]-4-substituted-2,4-dihydro-3H-1,2,4 triazole-3-thiones in the final step. The synthesized derivatives were evaluated for cytotoxicity and anticancer activity in vitro using the MTT (3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) colorimetric method against VERO, HEPG2 (human hepatocellular liver carcinoma), SKOV3 (ovarian carcinoma), MCF7 (human breast adenocarcinoma), PC3 and DU145 (prostate carcinoma) cells at 10-5 M (10 MUM) for 24 h. Compounds 5d and 5h showed the best biological potency against the SKOV3 cancer cell line (IC50 = 7.22 and 5.10 MUM, respectively) and did not display cytotoxicity toward VERO cells compared to etodolac. Compounds 5k, 5s, and 5v showed the most potent biological activity against the PC3 cancer cell line (IC50 = 8.18, 3.10, and 4.00 MUM, respectively) and did not display cytotoxicity. Moreover, these compounds were evaluated for caspase-3, -9, and -8 protein expression and activation in the apoptosis pathway for 6, 12, and 24 h, which play a key role in the treatment of cancer. In this study, we also investigated the apoptotic mechanism and molecular modeling of compounds 5k and 5v on the methionine aminopeptidase (type II) enzyme active site in order to get insights into the binding mode and energy. PMID- 29575046 TI - Enhancing integration of articular cartilage grafts via photochemical bonding. AB - The integration of osteochondral grafts to native articular cartilage is critical as the lack of graft integration may lead to continued tissue degradation, poor load transfer and inadequate nutrient transport. Photochemical bonding promotes graft integration by activating a photosensitizer at the interface via a light source and avoids negative effects associated with other bonding techniques. We hypothesized that the bond strength depends on photosensitizer type and concentration in addition to light exposure. Photochemical bonding was evaluated using methylene blue (MB), a cationic phenothiazine photosensitizer, and two phthalocyanine photosensitizers, Al(III) phthalocyanine chloride tetrasulfonic acid (CASPc) and aluminum phthalocyanine chloride (AlPc). Exposure was altered by varying irradiation time for a fixed irradiance or by varying irradiance with a fixed irradiation time. MB was ineffective at producing bonding at the range of concentrations tested while CASPc produced a peak twofold bond strength increase over controls. AlPc produced substantial bonding at all concentrations with a peak 3.9-fold bond strength increase over controls. Parametric tests revealed that bond strength depended primarily on the total energy delivered to the bonding site rather than the rate of light delivery or light irradiance. Bond strength persisted for 1 week of in-vitro culture, which warrants further exploration for clinical applications. These studies indicate that photochemical bonding is a viable strategy for enhancing articular cartilage graft integration. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

AB - This study tested the applicability of the individual and family self-management theory (IFSMT) to self-management (SM) in patients with left ventricular assist devices (LVADs). From an existing data set, we extracted the following variables that correspond to IFSMT's conceptual dimensions: anxiety, depression, and cognition (context dimension); self-efficacy (SM process dimension); adherence and quality of life (QOL; outcome dimensions). Descriptive statistics and partial least squares path modeling procedures were used for data analyses. A total of 100 patients (mean age 52 +/- 13.4 years) with continuous flow LVAD designs comprised the present study. Most patients were White (78%), married (69%), college-educated (72%), and on disability (53%). Their mean anxiety and depression scores were slightly above normal, while their cognitive function scores were slightly lower than normal. LVAD care self-efficacy, adherence, and QOL were within normal ranges. Factor loadings ranged from 0.50 to 1.0, and there were significant forward path relationships among the context, process, and outcome dimensions (beta ranges from 0.02 to 0.60, all P values < 0.05). In conclusion, the IFSMT provides a good fit for SM in LVAD. Further research is needed to clarify how best to improve LVAD SM practice and treatment outcomes. PMID- 29575047 TI - Assessment of MR-based R2* and quantitative susceptibility mapping for the quantification of liver iron concentration in a mouse model at 7T. AB - PURPOSE: To assess the feasibility of quantifying liver iron concentration (LIC) using R2* and quantitative susceptibility mapping (QSM) at a high field strength of 7 Tesla (T). METHODS: Five different concentrations of Fe-dextran were injected into 12 mice to produce various degrees of liver iron overload. After mice were sacrificed, blood and liver samples were harvested. Ferritin enzyme linked immunosorbent assay (ELISA) and inductively coupled plasma mass spectrometry were performed to quantify serum ferritin concentration and LIC. Multiecho gradient echo MRI was conducted to estimate R2* and the magnetic susceptibility of each liver sample through complex nonlinear least squares fitting and a morphology enabled dipole inversion method, respectively. RESULTS: Average estimates of serum ferritin concentration, LIC, R2*, and susceptibility all show good linear correlations with injected Fe-dextran concentration; however, the standard deviations in the estimates of R2* and susceptibility increase with injected Fe-dextran concentration. Both R2* and susceptibility measurements also show good linear correlations with LIC (R2 = 0.78 and R2 = 0.91, respectively), and a susceptibility-to-LIC conversion factor of 0.829 ppm/(mg/g wet) is derived. CONCLUSION: The feasibility of quantifying LIC using MR-based R2* and QSM at a high field strength of 7T is demonstrated. Susceptibility quantification, which is an intrinsic property of tissues and benefits from being field-strength independent, is more robust than R2* quantification in this ex vivo study. A susceptibility-to-LIC conversion factor is presented that agrees relatively well with previously published QSM derived results obtained at 1.5T and 3T. PMID- 29575049 TI - Molecular detection of fungi of public health importance in wild animals from Southern Brazil. AB - Some animals have an important relationship with fungal infections, and searching for pathogens in animal samples may be an opportunity for eco-epidemiological research. Since studies involving wildlife are generally restricted, using samples from road kills is an alternative. The aim of this study was to verify whether pathogenic fungi of public health importance occur in wildlife road kills from Santa Catarina State, Brazil. Organ samples (n = 1063) from 297 animals were analysed according to Polymerase Chain Reaction (PCR) using universal primers to detect fungi in general and, subsequently, using primers specific to Paracoccidioides brasiliensis, Histoplasma capsulatum and Cryptococcus spp. There were 102 samples positive for fungal species. Eight samples were positive for P. brasiliensis, three samples were positive for Cryptococcus spp. and one sample had coinfection by these two fungi. No sample was positive for Histoplasma spp. according to the molecular detection. Genetic sequencing allowed the identification of Fungal sp. in 89 samples, Cryptococcus neoformans in two samples and Aspergillus penicillioides in three samples. This study shows the importance of wild animals in the epidemiology of fungal infections and assists in the mapping of pathogen occurrence in a region that was not previously evaluated. PMID- 29575050 TI - Impact of HIV infection and highly active antiretroviral therapy (HAART) on B cell subpopulations in children. AB - B-cells play an important role in defending children against various infections. In view of scare data, we undertook this prospective cohort study to describe B cell compartment in HIV infected children (<5 years of age) and the effect of HAART on B cell subpopulations. HIV infected children (<5 years) from Pediatric HIV services of the Department of Pediatrics, All India Institute of Medical Sciences, New Delhi, were recruited (April 2012-December 2015). The enrolled HIV 1 infected children (n = 59) were followed up regularly for 12 months; healthy controls (n = 51) included HIV uninfected children with no major illness. Flow cytometry was performed on fresh EDTA-treated blood samples to characterize B cell subpopulations. In HIV-infected children, marked depletion of naive (P = 0.003), non-switched memory (P = 0.02), mature (P = 0.0005), resting memory (P < 0.0001) B cells, and expansion of double negative memory (P < 0.0001), activated memory (P < 0.0001) and tissue like memory (P < 0.0001) B cells were observed as compared to healthy controls. In children started on HAART, at the end of 12 months of therapy, frequencies of non-switched memory (P = 0.04), switched memory (P = 0.01), and resting memory (P = 0.003) B cells were lower; activated memory (P = 0.04), and tissue-like memory (P = 0.0001) B cells were still higher than healthy controls. HIV infection resulted in reduced memory B cells in HIV infected children. Following HAART, there was normalization of some B cell subpopulations. The study emphasizes the need of re-vaccination in HIV infected children to maintain the memory B cell pool and adequate humoral immune response against infections. PMID- 29575051 TI - Relationships between dysphagia and tongue pressure during swallowing in Parkinson's disease patients. AB - Although dysphagia is a life-threatening problem in patients with Parkinson's disease (PD), the pathophysiology of oropharyngeal dysphagia is yet to be understood. This study investigated the tongue motor function during swallowing in relation to dysphagia and the severity of PD. Thirty patients with PD (14 males and 16 females; average age, 69.4 years), Hoehn and Yahr stage II-IV, in Osaka University Hospital are participated in this study. During swallowing 5 ml of water, tongue pressure on the hard palate was measured using a sensor sheet with 5 measuring points. The maximal tongue pressure at each measuring point during swallowing was compared between patients with PD and healthy controls. Subjective assessment of oropharyngeal dysphagia was performed using Swallowing Disturbance Questionnaire-Japanese. The maximal tongue pressure at each measuring point was significantly lower in patients with PD than in healthy controls (8 males and 12 females; average age, 71.6 years). Furthermore, the maximal tongue pressure was significantly lower in dysphagic PD patients than non-dysphagic PD patients. Loss of tongue pressure production at the anterior part of the hard palate was strongly related to dysphagia in the oral phase as well as in the pharyngeal phase. An abnormal pattern of tongue pressure production was more frequently observed in dysphagic PD patients than in non-dysphagic PD patients. The results suggest that tongue pressure measurement might be useful for early and quantitative detection of tongue motor disability during swallowing in patients with PD. PMID- 29575052 TI - Expression profile of pattern recognition receptors in skeletal muscle of SOD1(G93A) amyotrophic lateral sclerosis (ALS) mice and sporadic ALS patients. AB - AIMS: Amyotrophic lateral sclerosis (ALS) is characterized by degeneration of motoneurons and progressive muscle wasting. Inflammatory processes, mediated by non-neuronal cells, such as glial cells, are known to contribute to disease progression. Inflammasomes consist of pattern recognition receptors (PRRs), apoptosis-associated speck-like protein (ASC) and caspase 1 and are essential for interleukin (IL) processing and a rapid immune response after tissue damage. Recently, we described inflammasome activation in the spinal cord of ALS patients and in SOD1(G93A) ALS mice. Since pathological changes in the skeletal muscle are early events in ALS, we hypothesized that PRRs might be abnormally expressed in muscle fibre degeneration. METHODS: Western blot analysis, real-time PCR and immunohistochemistry were performed with muscle tissue from presymptomatic and early-symptomatic male SOD1(G93A) mice and with muscle biopsies of control and sporadic ALS (sALS) patients. Analysed PRRs include nucleotide-binding oligomerization domain-like (NOD-like) receptor protein 1 (NLRP1), NLR protein 3 (NLRP3), NLR family CARD domain-containing 4 (NLRC4) and absent in melanoma 2. Additionally, expression levels of ASC, caspase 1, interleukin 1 beta (IL1beta) and interleukin 18 (IL18) were evaluated. RESULTS: Expression of PRRs and ASC was detected in murine and human tissue. The PRR NLRC4, caspase 1 and IL1beta were significantly elevated in denervated muscle of SOD1(G93A) mice and sALS patients. Furthermore, levels of caspase 1 and IL1beta were already increased in presymptomatic animals. CONCLUSION: Our findings suggest that increased inflammasome activation may be involved in skeletal muscle pathology in ALS. Furthermore, elevated levels of NLRC4, caspase 1 and IL1beta reflect early changes in the skeletal muscle and may contribute to the denervation process. PMID- 29575053 TI - Captive chimpanzee (Pan troglodytes) behavior as a function of space per animal and enclosure type. AB - Space per animal, or animal density, and enclosure type are important elements of functionally appropriate captive environments (FACEs) for chimpanzees. The National Institutes of Health (NIH) recommends that captive chimpanzees be maintained in areas of >250 ft2 /animal. Several studies have investigated chimpanzee behavior in relation to space per animal, but only two studies have examined these variables while attempting to hold environmental complexity constant. Both have found few, if any, significant differences in behavior associated with increased space per animal. The NIH does not provide recommendations pertaining to enclosure type. Although PrimadomesTM and corrals are considered acceptable FACE housing, no studies have investigated chimpanzee behavior in relation to these two common types of enclosures. We examined the NIH space per animal recommendation, and the effects of enclosure type, while maintaining similar levels of environmental complexity. We used focal animal observations to record the behavior of 22 chimpanzees in three social groups following within-facility housing transfers. Chimpanzees that were moved from an area with space below the NIH recommendation to the same type of enclosure with space above the recommendation (dome to double dome) exhibited significantly more locomotion and behavioral diversity post-transfer. Chimpanzees that were moved from an area with space below the recommendation to a different type of enclosure with space above the recommendation (dome to corral) exhibited significant increases in foraging and behavioral diversity, and a decrease in rough scratching. Lastly, chimpanzees that were moved from an area above the recommendation to a different enclosure type with space equal to the recommendation (corral to double dome) exhibited an increase in behavioral diversity. These results add to the body of literature that addresses the concept of specific minimum space requirements per chimpanzee, and highlight the need for more empirical investigation of the relationship between space per chimpanzee, behavior, and welfare.

PMID- 29575055 TI - MicroRNA-190b regulates lipid metabolism and insulin sensitivity by targeting IGF 1 and ADAMTS9 in non-alcoholic fatty liver disease. AB - Nonalcoholic fatty liver disease (NAFLD) is characterized by ectopic lipid accumulation and insulin resistance, yet the underlying molecular mechanisms are poorly understood. MiR-190b is thought to play a role in hepatocellular carcinoma by modulating insulin resistance; however, its role in NAFLD remains unknown. Here, we found that miR-190b expression was significantly increased in the liver tissues of patients with NAFLD, compared to normal tissues. Moreover, miR-190b was upregulated in a high-fat diet NAFLD mouse model and a free fatty acid induced NAFLD cellular model. Knockdown of miR-190b decreased aspartate transaminase (AST), alanine transaminase (ALT), triglyceride (TG), and total cholesterol (TC). It also reduced expression of the lipogenic genes fatty acid synthase (FAS) and 3-hydroxy-3-methylglutarylCoA reductase (HMGCR), alleviated hepatic steatosis, improved glucose tolerance, elevated insulin sensitivity, and activated insulin receptor substrate (IRS)2/Akt signaling in vivo and/or in vitro. Furthermore, we confirmed that miR-190b directly targeted IGF-1 and ADAMTS9. MiR-190b overexpression suppressed expression of IGF-1 and ADAMTS9, which were increased by miR-190b inhibition. Expression of IGF-1 and ADAMTS9 was inversely correlated with miR-190b in liver tissues of patients with NAFLD, respectively. We also found that IGF-1 or ADAMTS9 inhibition partially reversed the effects of miR-190b on lipid metabolism and insulin signaling in vitro. Taken together, the data reveal that miR-190b inhibition suppressed lipid accumulation and improved insulin sensitivity by targeting IGF-1 and ADAMTS9, suggesting that miR-190b inhibition may be a therapeutic strategy against NAFLD. PMID- 29575056 TI - Subgroup analysis with semiparametric models toward precision medicine. AB - In analyzing clinical trials, one important objective is to classify the patients into treatment-favorable and nonfavorable subgroups. Existing parametric methods are not robust, and the commonly used classification rules ignore the fact that the implications of treatment-favorable and nonfavorable subgroups can be different. To address these issues, we propose a semiparametric model, incorporating both our knowledge and uncertainty about the true model. The Wald statistics is used to test the existence of subgroups, while the Neyman-Pearson rule to classify each subject. Asymptotic properties are derived, simulation studies are conducted to evaluate the performance of the method, and then method is used to analyze a real-world trial data. PMID- 29575057 TI - Adiponectin synthesis and secretion by subcutaneous adipose tissue is impaired during obesity by endoplasmic reticulum stress. AB - Subcutaneous (SAT) and visceral (VAT) adipose tissues stores excess energy as triglycerides and synthesize adiponectin to prevent ectopic lipid accumulation and lipotoxicity. During obesity, an impairment in the capacity of SAT to store triglycerides and synthesize adiponectin is associated with increased free fatty acids (FFA) release, leading to VAT hypertrophy and hepatic and skeletal muscle lipotoxicity. Endoplasmic reticulum (ER) stress and the unfolded protein response (UPR) may be involved in SAT dysfunction during obesity. The objectives of this study were to assess UPR activation and adiponectin synthesis in: 1) SAT and VAT from mice exposed to acute pharmacologic or chronic obesity-induced ER stress and in 2) cultured mice primary mature adipocytes or adipocytes differentiated in vitro from SAT and VAT exposed to tunicamycin or thapsigargin. Mice fed a high fat diet developed obesity, increased FFA and lower circulating adiponectin in association with lower adiponectin synthesis and increased UPR markers in SAT. Mice subjected to acute ER stress by pioglitazone administration and a low-dose tunicamycin injection presented a maladaptive UPR activation in SAT along with reduced adiponectin synthesis and secretion and increased lipolysis with respect to VAT, associated with lipid accumulation in skeletal muscle and liver. Primary adipocytes and adipocytes differentiated from SAT exposed to pharmacologic ER stress also developed maladaptive UPR, along with reduced adiponectin synthesis and increased lipolysis with respect to those from VAT. Our results indicate that compared to VAT, SAT is more susceptible to ER stress, leading to increased lipolysis and reduced adiponectin synthesis and secretion. PMID- 29575058 TI - Amino acids as chiral derivatizing agents for antiproliferative substituted N benzyl isoindolinones. AB - The absolute configurations of the diastereomers of novel amino acid ester derivatives of 2,3-substituted isoindolinones, which are known as apoptosis activators due to their ability to inhibit the MDM2-p53 PPI, were assigned using NMR and computational methods. Procedures for diastereomer separation and determining the absolute configuration were developed to perform the study. The high significance of N-benzyl fragment for the determination of the diastereomer absolute configuration by NMR methods was established; it is determined by a number of factors inherent in this fragment and the structural features of the studied substrates. Analysis of the individual isomer activity showed that the target inhibitory effect of S- and R-isoindolinone L-valinates differs by less than 20%. It can be explained by the presence of a flexible linker between the isoindolinone core and amino acid fragment, which provides the optimal arrangement of the molecule in the hydrophobic cavity of MDM2 for both isomers. PMID- 29575059 TI - Simultaneous measurement of glutamate, glutamine, GABA, and glutathione by spectral editing without subtraction. AB - PURPOSE: To simultaneously measure glutamate, glutamine, gamma-aminobutyric acid (GABA), and glutathione using spectral editing without subtraction at 7T. METHODS: A novel spectral editing approach was proposed to simultaneously measure glutamate, glutamine, GABA, and glutathione using a TE of 56 ms at 7T. By numerical optimization of sequence timing in the presence of an editing pulse, the 4 metabolites all form relatively intense pseudo singlets with maximized peak amplitudes and minimized peak linewidths in 1 of the 3 interleaved spectra. For measuring glutamate, glutamine, and glutathione, the editing pulse targets the H3 protons of these metabolites near 2.12 parts per million. Both GABA H2 and H4 resonances are fully utilized in spectral fitting. RESULTS: Concentration levels (/[total creatine]) of glutamate, glutamine, GABA, and glutathione from an 8 mL voxel in the pregenual anterior cingulate cortex of 5 healthy volunteers were found to be 1.26 +/- 0.13, 0.33 +/- 0.06, 0.13 +/- 0.03, and 0.27 +/- 0.03, respectively, with within-subject coefficient of variation at 3.2%, 8.2%, 7.1%, and 10.2%, respectively. The total scan time was less than 4.5 min. CONCLUSIONS: The proposed new technique does not require data subtraction. The 3 major metabolites of the glutamatergic and GABAergic systems and the oxidative stress marker glutathione were all measured in 1 short scan with high precision. PMID- 29575060 TI - Real-life 3D therapy failure: Analysis of NS5A 93H RAS plus 108 K polymorphism in complex with ombitasvir by molecular modeling. AB - We report a real-life 3D therapy failure in a patient treated with ombitasvir (OMV)/paritaprevir/ritonavir and dasabuvir without ribavirin (3D-R). He had therapy failure at week 12 after the end of treatment. We detected resistance associated substitutions (RASs) plus polymorphisms on NS3, NS5A, and NS5B target regions by population sequencing (15% cut-off) at baseline, at relapse and during follow-up. About this, NS5A RASs generally persist longer than resistances in the other target genes and may impact treatment outcome. Therefore, to evaluate OMV drug-resistance mechanism, we studied the acquired RAS plus polymorphisms on NS5A phosphoprotein by computational studies. OMV showed a higher affinity towards baseline and 93H/108 K mutant structure (follow-up) with respect to 93H/R108 mutant structure (relapse) on phosphoprotein. By Molecular Dynamics simulations (MDs), structural information about the protein stability in presence of OMV were observed. According to our data, molecular modeling approach has proved to be a powerful method to evaluate the impact of these RASs plus specific amino acid (AA) changes on phosphoprotein. PMID- 29575062 TI - Restored response to ADP downstream of purinergic P2Y12 receptor in apheresis platelets after pathogen-reducing xenon flash treatment. AB - BACKGROUND: Our previous study revealed that pathogen-reducing filtered xenon flash-treated platelets (fXe-PLTs) showed sustained aggregation in response to adenosine diphosphate (ADP), but apheresis-collected PLTs (Aph-PLTs) showed reversible aggregation. STUDY DESIGN AND METHODS: Aph-PLTs, fXe-PLTs, and freshly prepared PLTs (PRP-PLTs) from whole blood were used to investigate the following responses to ADP: concentration response and effects of ADP receptor antagonists on aggregation, the cytosolic calcium (Ca2+ ) flux downstream of P2Y1 receptor signaling, and phosphorylation of vasodilator-stimulated phosphoprotein (VASP) and signaling intermediate protein Akt downstream of the P2Y12 receptor. RESULTS: The aggregation of Aph-PLTs by ADP (10 uM) changed from reversible to sustained in an fXe flash dose-dependent manner. The concentration-response curve of Aph PLTs showed a fivefold higher 50% effective concentration compared with PRP-PLTs, and fXe treatment decreased it to threefold. While the basal Ca2+ level was higher both in Aph- and fXe-PLTs than in PRP-PLTs, the increase of cytosolic Ca2+ by ADP remained unchanged in Aph- and PRP-PLTs, but was slightly reduced in fXe PLTs. Although the forskolin-induced VASP phosphorylation was significantly reduced in Aph-PLTs, and partially restored by the fXe treatment, ADP stimulation attenuated this phosphorylation to an equivalent extent among the three PLT types. The ADP-stimulated time-dependent Akt phosphorylation was weak in Aph PLTs, whereas fXe-PLTs and PRP-PLTs showed a marked increase. CONCLUSION: These results indicate that the reversible aggregation of Aph-PLTs is the consequence of insufficient Akt phosphorylation. The fXe treatment restores the increase of phosphorylated Akt, resulting in the sustained aggregation of fXe-PLTs similar to those of PRP-PLTs. PMID- 29575061 TI - Association between site-specific bone mineral density and glucose homeostasis and anthropometric traits in healthy men and women. AB - OBJECTIVE: Patients with type 2 diabetes mellitus have an increased risk of fracture despite normal or increased bone mineral density (BMD). Studies on the relationship of glucose homeostasis with BMD phenotypes have been inconclusive because distinguishing the roles of insulin resistance and hyperglycaemia in bone remodelling is challenging. In this study, we sought to define the relationship of site-specific BMD with glucose homeostasis traits and anthropometric traits. DESIGN/PATIENTS/MEASUREMENTS: In a cross-sectional study, we examined 787 subjects from the Mexican-American Coronary Artery Disease (MACAD) cohort who had undergone euglycaemic-hyperinsulinaemic clamps, oral glucose tolerance testing and dual X-ray absorptiometry. Glucose homeostasis traits included insulinogenic index (IGI30), insulin sensitivity (M value), insulin clearance (MCRI), fasting insulin, fasting glucose and 2-hour glucose. Univariate and multivariate analyses were performed to assess the association of glucose homeostasis and anthropometric traits with site-specific BMD. RESULTS: Two-hour glucose was negatively associated with arm BMD in women, which remained significant in multivariate analysis (beta = -.15, P = .0015). Positive correlations between fasting insulin and BMD at weight-bearing sites, including pelvis (beta = .22, P < .0001) and legs (beta = .17, P = .001) in women and pelvis (beta = .33, P < .0001) in men, lost significance after multivariate adjustment. Lean mass exhibited strong independent positive associations with BMD at multiple sites in both sexes. CONCLUSION: Our findings suggest that (i) anabolic effects of insulin might work via mechanical loading from lean mass; (ii) a direct negative effect of increasing glucose might be more prominent at cortical-bone-rich sites in women; and (iii) lean mass is a strong positive predictor of bone mass. PMID- 29575063 TI - A predominantly glial origin of axonal ribosomes after nerve injury. AB - Axonal mRNA transport and local protein synthesis are crucial for peripheral axon regeneration. To date, it remains unclear how ribosomes localize to axons. They may be co-transported with mRNAs or, as suggested by recent studies, transferred from Schwann cells (SC). Here, we generated transgenic "RiboTracker" mice expressing tdTomato-tagged ribosomal protein L4 in specific cell types when crossed with Cre lines. Two neuronal RiboTracker-Cre lines displayed extremely low levels of axonal L4-tdTomato-positive ribosomes. In contrast, two glial RiboTracker-Cre lines revealed tagged ribosomes in sciatic nerve (SN) axons with increasing amounts after injury. Furthermore, non-RiboTracker dorsal root ganglia co-cultured with L4-tdTomato-expressing SCs displayed tagged ribosomes in axons. These data provide unequivocal evidence that SN axons receive ribosomes from SCs upon injury and indicate that glial cells are the main source of axonal ribosomes.

PMID- 29575065 TI - Evidence for the role of INSL3 on sperm production in boars by passive immunisation. AB - Insulin-like factor 3 (INSL3), previously called relaxin-like factor, is essential for foetal testis descent and has been implicated in sperm production in adult males. This study investigated the role of INSL3 in sperm production by examining the effect of neutralising INSL3 by passive immunisation on testicular function and sperm output in boars. Six male Duroc boars were randomly assigned to passive immunisation and control groups (n = 3 each). The immunisation group was intravenously injected with an IgG fraction of anti-INSL3 antibody developed against the B domain of INSL3 at 2-week intervals from 21-40 weeks of age. The control group was treated with normal IgG in the same manner. Antibody administration reduced testis weight and caused a fourfold increase in the frequency of apoptotic germ cells, which was associated with upregulation of the pro-apoptotic caspase 3 and BAX, and downregulation of the anti-apoptotic XIAP and BCL2, and a substantial marked reduction in sperm concentration. Neutralising INSL3 delivered by passive immunisation reduced testis weight and sperm concentration by inducing germ cell apoptosis, suggesting that INSL3 acts as a germ cell survival/anti-apoptotic factor in the maintenance of sperm production. PMID- 29575066 TI - High speed ink aggregates are ejected from tattoos during Q-switched Nd:YAG laser treatments. AB - INTRODUCTION: Dark material has been observed embedded within glass slides following Q-switched Nd:YAG laser treatment of tattoos. It appears that these fragments are ejected at high speed from the skin during the treatment. METHOD: Light microscopic analysis of the slides reveals aggregates of dark fragmented material, presumably tattoo ink, with evidence of fractured/melted glass. Photomicrographs reveal that the sizes of these aggregates are in the range 12 MUm to 0.5 mm. RESULTS: Tattoo ink fragments were clearly observed on the surface and embedded within glass slides. Surface aggregates were observed as a fine dust and were easily washed off while deeper fragments remained in situ. The embedded fragments were not visible to the unaided eye. Some fragments appeared to have melted yielding an "insect-like" appearance. These were found to be located between approximately 0.2 and 1 mm deep in the glass. CONCLUSION: Given the particle masses and kinetic energies attained by some of these aggregates their velocities, when leaving the skin, may be hundreds to thousands of metres per second. However, the masses of the aggregates are minuscule meaning that laser operators may be subjected to these high-speed aggregates without their knowledge. These high-speed fragments of ink may pose a contamination risk to laser operators. Lasers Surg. Med. 9999:1-7, 2018. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND/OBJECTIVES: Despite their ubiquitous use and several recent health controversies involving cosmetics and personal care products for children, the Food and Drug Administration has little oversight of these products and relies on consumer-submitted adverse event reports. We assessed the recently released Center for Food Safety and Applied Nutrition's Adverse Event Reporting System database for adverse event reports submitted to the Food and Drug Administration for baby personal care products and to determine whether useful insights can be derived. METHODS: We extracted the Center for Food Safety and Applied Nutrition's Adverse Event Reporting System data file from 2004 to 2016 and examined the subset classified according to the Food and Drug Administration-designated product class as a baby product. Events were manually categorized into product type and symptom type to assess for trends. RESULTS: Only 166 total adverse events were reported to the Food and Drug Administration for baby products from 2004 to 2016. The majority of reports indicated rash or other skin reaction; 46% of reported events led to a health care visit. CONCLUSION: Pediatric dermatologists should consider submitting cosmetics and personal care product adverse event reports and encouraging consumers to do so likewise in situations in which a product adversely affects a child's health.

AB - Most animals hold the ability to regenerate damaged cells, tissues, and even any lost part of their bodies. To date, there is little known about the precise regulatory mechanism of regeneration and many fundamental questions remain unanswered. To further understand the precise regulatory mechanism of regeneration, we used planarian Dugesia japonica as a model and sequenced the transcriptomes of their regenerated tissues at different regeneration stages. Through de novo assembly and expression profiling, we found that Heat shock protein and MAPK pathway were involved into early response of regeneration in D. japonica. In addition, immune response, cell proliferation, and migration were activated during regeneration. Of notes, our results revealed a specific functional role of programmed cell death (PCD) in regeneration of D. japonica. PCD may not only remove the damaged and superfluous tissues for further patterning with regenerated tissues, but also provide signals to trigger neoblasts proliferation and differentiation directly. Together, our results revealed Heat shock protein and MAPK pathway mediated early response of regeneration and found a dual role of PCD in regeneration D. japonica. Meanwhile, we constructed regulatory networks of apoptosis, autophagy, and related signaling pathways and proposed a schematic model, which provided a global landscape of regeneration. PMID- 29575082 TI - Somatic sprouts of the Purkinje cells in a patient with multiple system atrophy. AB - We describe the post mortem case of a 71-year-old Japanese woman diagnosed as having multiple system atrophy (MSA), showing somatic sprouting formation of Purkinje cells. The patient had suffered from frequent falling episodes and clumsiness of the left hand since the age of 67 years. Orthostatic hypotension and parkinsonism subsequently emerged. Typical neuropathological features of MSA, including degeneration of the striatum, pontine base and cerebellum with abundance of phosphorylated alpha-synuclein-positive neuronal and glial cytoplasmic and nuclear inclusions in the brain, were observed. In addition to gliosis of the cerebellar white matter and notable loss of Purkinje cells, several Purkinje cells showed somatic sprouting. Somatic sprouting of Purkinje cells has been demonstrated in several specific conditions, such as developing brains and several neurodegenerative disorders, including Menkes kinky hair disease, familial spinocerebellar ataxia, acute encephalopathy linked to familial hemiplegic migraine, and Huntington's disease; however, no MSA cases have been reported with sprouting from the soma of Purkinje cells. Axonal damage caused by oligodendroglial dysfunction could be crucial in the development of Purkinje cell loss in MSA. Moreover, no apparent alpha-synuclein accumulation has been described in the Purkinje cells of MSA. We propose that MSA is another degenerative disorder associated with somatic sprouts of Purkinje cells.

AB - : Cronobacter is a ubiquitous Gram-negative pathogen bacterium capable of surviving in low water activity environments, in particular powdered infant formula (PIF). Seven Cronobacter strains representing four different species (C. sakazakii, n = 4; C. malonaticus, n = 1; C. muytjensii, n = 1; C. turicensis, n = 1) were subjected to dry stress and stored in PIF at room temperature. The resulting survivor curves showed that Cronobacter sp. can survive for extended periods of at least 3 months with a significant, but moderate, variability regarding the level of resistance between species; however, no correlation was evident regarding the origin of strains. These results are evaluated with regard to other key characteristics, including genomic profiles and biofilm formation capacities of the strains. SIGNIFICANCE AND IMPACT OF THE STUDY: Cronobacter can survive extended periods of at least 3 months in PIF, with moderately significant interspecific variability in desiccation resistance. Results are evaluated with regard to genomic profiles and biofilm formation capacities of the strains, and contribute to an improved understanding of the environmental persistence of Cronobacter in contaminated PIF, and subsequent risk to infant exposure. PMID- 29575084 TI - Inhibition of PSMD4 alters ZP1 ubiquitination state and sperm-oocyte-binding ability in pigs. AB - The aim of this study was to determine how the duration of culture affects the ubiquitination of zona pellucida (ZP) proteins (ZP1, ZP2 and ZP3) during porcine oocyte maturation in vitro. We analysed the changes in ZP protein ubiquitination under three conditions: (i) during oocyte maturation from stage GV to MII; (ii) in oocytes cultured for different periods of time; and (iii) in oocytes treated with an antibody against PSMD4. Our results show that ZP1 and ZP2 are ubiquitinated at the GV stage, while ZP1, ZP2 and ZP3 are ubiquitinated at the MII stage, and band intensities for these proteins were significantly different between the GV and MII stages (p < .05). We also found that ubiquitination occurs in ZP1, ZP2 and ZP3 after cultured for 46, 52, 58 and 64 hr, and that the level of ubiquitinated ZP1 was significantly different in oocytes that were cultured for different time periods. Finally, treatment with an antibody against PSMD4 resulted in a significant decrease in ZP1 ubiquitination (p < .05), without affecting ZP2 or ZP3. The number of attached sperms per oocyte was also significantly different between control and anti-PSMD4-treated groups. Thus, we concluded that ZP1 and ZP2 are ubiquitinated at the GV stage, and ZP1, ZP2 and ZP3 are ubiquitinated at the MII stage. As the duration of culture increases, the ubiquitination levels of ZP proteins decrease. We also found that PSMD4 improves ZP1 ubiquitination during in vitro culture of porcine oocytes and effectively inhibits sperm-oocyte binding.

AB - AIMS: To investigate the associations of eHealth Literacy with health-promoting behaviours among hospital nurses in South Korea. BACKGROUND: Health-promoting behaviours of nurses are crucial for their own improved health and health-related behaviours of patients. eHealth literacy refers to the ability to search, understand and evaluate health information available online. With the growing use of the Internet, eHealth literacy is emerging as an important factor enhancing health-promoting behaviours. DESIGN: Descriptive cross-sectional design with self reported questionnaires. METHODS: Data were collected between March-May 2016 from five hospitals in South Korea. Health-promoting behaviours and eHealth literacy were assessed using Health Promoting Lifestyle Profile-II and K-eHEALS, respectively. Multiple linear regression models were used to examine the associations of eHealth literacy and health-promoting behaviours. RESULTS: Nurses with high level of eHealth literacy had significantly positive overall health promoting behaviours, stress management, interpersonal relations, self actualization and health responsibility, but not for nutrition and physical activity. CONCLUSION: Improving eHealth literacy through various strategies could be an effective way to boost health-promoting behaviours among nurses. However, improvement of actual health-promoting behaviours such as nutrition and physical activity will require systematic and organizational changes. PMID- 29575086 TI - Application of noninvasive prenatal testing in pregnancies with fetal double bubble sign: Is it feasible? AB - OBJECTIVE: To evaluate the application of noninvasive prenatal testing as an alternative to invasive diagnostic testing in pregnancies with the double bubble sign. METHODS: This was a retrospective analysis of 92 pregnancies with fetal double bubble identified by prenatal ultrasound, in which invasive diagnostic testing was performed for genetic investigations using quantitative fluorescence PCR and chromosomal microarray. Noninvasive prenatal testing was assumed to provide to patients for screening for the common aneuploidies. RESULTS: Fetal trisomy 21 was detected in 8 of the 92 patients with prenatal double bubble. No other chromosomal anomalies or microscopic pathogenic copy-number variations (CNV) were found. Noninvasive prenatal testing could theoretically identified the affected pregnancies with trisomy 21 in this group with decreased number of invasive diagnostic testing. CONCLUSIONS: Noninvasive prenatal testing could be recommended for genetic evaluation of the etiology of prenatal double bubble after thorough pretest counseling. PMID- 29575087 TI - Addressing sexual issues in palliative care: A qualitative study on nurses' attitudes, roles and experiences. AB - AIM: To explore palliative care nurses' attitudes, roles and concrete experience with regard to addressing sexual issues in their daily practice. BACKGROUND: Patients and their partners in palliative care might experience dramatic changes in their sexuality and want nurses to provide the opportunity to address them. Moreover, it is argued that the holistic philosophy of palliative care encourages nurses working in this area to include sexual issues in their daily care. It is, however, unknown how palliative care nurses address sexual issues. DESIGN: A generic qualitative study was performed. METHODS: In total, 21 in-depth interviews were done with nurses from different facilities of palliative care networks in Flanders. Data were collected between September 2014 - September 2016 and thematic analysis was used to analyse the data. RESULTS: It was found that the way palliative care nurses addressed sexual issues was clearly influenced by their own interpretation of the philosophical principles underlying palliative care. The different interpretations of these basic principles create tensions for nurses about how to address sexual issues in the daily practice of palliative care and nurses vary in their reactions to these tensions. The present findings show that palliative care nurses - when they were able to overcome these tensions - use a "sex-positive approach" that fits with their tendency to focus on quality of life. CONCLUSION: Out of the results of this study, we made a list of good practices for palliative care nurses addressing sexual issues. This list can be used in nursing educational programs.

PMID- 29575089 TI - Skin toxicology and 3Rs-Current challenges for public health protection. AB - Driven by the fast paced development of complex test systems in vitro, mass spectrometry and omics, we finally have the tools to unravel the molecular events that underlie toxicological adversity. Yet, timely regulatory adaptation of these new tools continues to pose major challenges even for organs readily accessible such as skin. The reasons for this encompass a need for conservatism as well as the need of tests to serve an existing regulatory framework rather than to produce scientific knowledge. It is important to be aware of this in order to align regulatory skin toxicity with the 3R principles more readily. While most chemical safety testing is still based on animal data, regulatory frameworks have seen a strong push towards non-animal approaches. The endpoints corrosion, irritation, sensitisation, absorption and phototoxicity, for example, can now be covered in vitro with the corresponding test guidelines (TGs) being made available by the OECD. However, in vitro approaches tend to be more reductionist. Hence, a combination of several tests is usually preferable to achieve satisfying predictivity. Moreover, the test systems and their combined use need to be standardised and are therefore subject not only to validation but also to the ongoing development of so-called integrated approaches to testing and assessment (IATAs). Concomitantly, skin models are being refined to deliver the complexity required for increased applicability and predictivity. Given the importance of regulatory applicability for 3R-derived approaches to have a long-lasting impact, this review examines the state of regulatory implementation and perspectives, respectively. PMID- 29575090 TI - Gait mechanics and tibiofemoral loading in men of the ACL-SPORTS randomized control trial. AB - The risk for post-traumatic osteoarthritis is elevated after anterior cruciate ligament reconstruction (ACLR), and may be especially high among individuals with aberrant walking mechanics, such as medial tibiofemoral joint underloading 6 months postoperatively. Rehabilitation training programs have been proposed as one strategy to address aberrant gait mechanics. We developed the anterior cruciate ligament specialized post-operative return-to-sports (ACL-SPORTS) randomized control trial to test the effect of 10 post-operative training sessions consisting of strength, agility, plyometric, and secondary prevention exercises (SAPP) or SAPP plus perturbation (SAPP + PERT) training on gait mechanics after ACLR. A total of 40 male athletes (age 23 +/- 7 years) after primary ACLR were randomized to SAPP or SAPP + PERT training and tested at three distinct, post-operative time points: 1) after impairment resolution (Pre training); 2) following 10 training sessions (Post-training); and 3) 2 years after ACLR. Knee kinematic and kinetic variables as well as muscle and joint contact forces were calculated via inverse dynamics and a validated electromyography-informed musculoskeletal model. There were no significant improvements from Pre-training to Post-training in either intervention group. Smaller peak knee flexion angles, extension moments, extensor muscle forces, medial compartment contact forces, and tibiofemoral contact forces were present across group and time, however the magnitude of interlimb differences were generally smaller and likely not meaningful 2 years postoperatively. Neither SAPP nor SAPP + PERT training appears effective at altering gait mechanics in men in the short-term; however, meaningful gait asymmetries mostly resolved between post training and 2 years after ACLR regardless of intervention group.

AB - We describe the difficulties of treating acne in a series of female-to-male transgender adolescents, including concerns about potential hepatotoxicity with concomitant use of testosterone with isotretinoin or tetracyclines. Acne is a foreseeable adverse effect of testosterone treatment in transgender adolescents, so monitoring for acne is advised. The treatment of acne in transgender adolescents is important given that severe acne and transgenderism are associated with higher rates of depression and suicide.

AB - This study aimed to assess whether T-lymphokine-activated killer cell-originated protein kinase (TOPK) can be a potent novel biomarker to predict the outcome in patients with primary central nervous system lymphoma (PCNSL). This study enrolled 20 patients who were histologically diagnosed as having diffuse large B cell type PCNSL between 2005 and 2015. Using surgical specimens, the expression of TOPK and phosphorylated TOPK (p-TOPK) was analyzed on immunohistochemistry. Clinical features such as age, sex, Karnofsky performance status (KPS), ocular involvement, deep brain structure involvement, the number of lesions, chemotherapy and radiation therapy were also collected. Impacts of TOPK/p-TOPK expression on their progression-free survival (PFS) and overall survival (OS) were examined with multivariate analysis. Median PFS/OS were 24.2 and 39.0 months, respectively. On immunostaining, the mean percentage of TOPK-positive cells was 35.5 +/- 20.8%, and the mean number of p-TOPK-positive cells was 13.7 +/- 15.7 cells/mm2 . The higher expression of p-TOPK was significantly related to multiple lesions (P = 0.003). Multivariate analysis demonstrated that only the higher expression of p-TOPK was an independent predictor to shorten both PFS (P = 0.029; hazard ratio (HR), 5.5; 95% confidential interval (CI), 1.2-25.3) and OS (P = 0.014; HR, 7.7; 95% CI, 1.5-41.3). These findings strongly suggest that p TOPK may be a potent biomarker to determine the outcome of patients with PCNSL and to develop novel drugs to treat PCNSL.

AB - When seeds are exposed to drought and salinity during germination, newly germinated embryos stop growth and enter a quiescent state called postgerminative growth (PGG) arrest. PGG arrest protects embryos from the stress, but it is not known how PGG is restored from the arrest when stress is eased. In this study, we show that under stress- or abscisic acid-induced PGG arrest conditions, Arabidopsis thaliana Raf-type protein kinase 22 (AtRaf22) overexpression accelerated photoautotrophic seedling establishment, whereas atraf22 knockout mutations enhanced the arrest. Furthermore, when the stress intensity was reduced subsequently, AtRaf22 overexpression plants resumed growth and accomplished photoautotrophic transition much faster than the knockout or wild-type plants. These results suggest that AtRaf22 activity is important for maintaining growth capacity during stress-induced PGG arrest, which is most likely critical for competitive growth when the stress subsides and plants resume growth. Such a factor has not been reported before.

PMID- 29575096 TI - Clinical application of endothelial injury marker in hypertensive patients. AB - PURPOSE: Endothelial damages are one of the most important causes of persistent hypertensive complications. The aim of our study was to discuss the relationship between the molecular markers of endothelial damage, thrombomodulin, and complications in hypertension. METHODS: A total 132 cases of hypertensive patients, including 13 patients with damage of target organs, were selected as research subjects. And grouping was based on different levels of blood pressure. The blood pressure and thrombomodulin levels were detected among all cases, and their drinking, smoking, and other medical records were tracked. RESULTS: Higher plasma concentration of thrombomodulin was demonstrated in subjects with hypertensive complications compared with without complications [24.5 (18.1,37.55) vs 12.1 (9.1,22.3) TU/mL, P = .001, respectively]. The optimum thrombomodulin cutoff value was determined to be more than 15.5 TU/mL, with a sensitivity of 92.3% and a specificity of 63%. With the increase in blood pressure level, thrombomodulin levels in three groups gradually raised [6.15(5.475,12.75) vs 9.75(7.725,13.35) vs 16.45 (10.125,23.725) TU/mL, P = .007, respectively]. CONCLUSION: With the increase in blood pressure and the occurrence of complications, thrombomodulin showed an increasing trend, which was caused by an increase in the degree of endothelial injury. So, thrombomodulin may serve as a clinically meaningful marker of the progression of hypertension. PMID- 29575097 TI - Evaluation and Comparison of Hemodynamic Performance of Three ECLS Systems in a Simulated Adult Cardiogenic Shock Model. AB - The objective of this study was to evaluate three commercially available ECLS systems with rotary pumps in terms of circuit pressure, pressure drop, perfusion modes, and hemodynamic energy transmission in a simulated adult cardiogenic shock model. One circuit consisted of a Cardiohelp system, which included a Cardiohelp console and HLS Module Advanced 7.0 tubing set with integrated centrifugal pump and oxygenator. The alternative circuit was composed of a Quadrox-D Adult oxygenator connected in series with either an i-cor diagonal pump and console or a Rotaflow centrifugal pump and console. The circuit was primed with lactated Ringer's solution and packed red blood cells (hematocrit 40%). The trials were conducted at flow rates of 1-5 L/min with pseudo patient pressures of 60 mm Hg and 80 mm Hg. Pulsatile flow was tested when using the i-cor system. Mean pre oxygenator pressure and pressure drop across ECLS circuit (including oxygenator and arterial tubing) were lower when using the Cardiohelp system as compared to the Rotaflow and i-cor systems (P < 0.01). The i-cor system was able to deliver more hemodynamic energy to the pseudo patient because of its ability to produce pulsatile flow (P < 0.01). The Cardiohelp HLS Module Advanced 7.0 integrated oxygenator had a lower resistance than the Quadrox-D oxygenator. Although the compact Cardiohelp system had a better hemodynamic performance when compared to Rotaflow and i-cor systems, the pulsatile flow of the i-cor system delivered more hemodynamic energy to the pseudo patient. This may render more physiological benefits in high-risk patients on ECLS. PMID- 29575094 TI - The relationship between frailty and polypharmacy in older people: A systematic review. AB - AIMS: Frailty is a complex geriatric syndrome resulting in decreased physiological reserves. Frailty and polypharmacy are common in older adults and the focus of extensive studies, although little is known about the impact they may have on each other. This is the first systematic review analysing the available evidence on the relationship between frailty and polypharmacy in older adults. METHODS: Systematic review of quantitative studies. A comprehensive literature search for publications in English or Spanish was performed on MEDLINE, CINAHL, the Cochrane Database and PsycINFO in September 2017 without applying restrictions on the date of publication. Studies reporting any relationship between frailty and polypharmacy in older adults were considered. RESULTS: A total of 25 publications were included, all of them observational studies. Evaluation of Fried's frailty criteria was the most common approach, followed by the Edmonton Frail Scale and FRAIL scale. Sixteen of 18 cross sectional analyses and five of seven longitudinal analyses demonstrated a significant association between an increased number of medications and frailty. The causal relationship is unclear and appears to be bidirectional. Our analysis of published data suggests that polypharmacy could be a major contributor to the development of frailty. CONCLUSIONS: A reduction of polypharmacy could be a cautious strategy to prevent and manage frailty. Further research is needed to confirm the possible benefits of reducing polypharmacy in the development, reversion or delay of frailty.

PMID- 29575099 TI - Lack of association between SLCO1B1 polymorphisms and lipid-lowering response to simvastatin therapy in Thai hypercholesterolaemic patients. AB - WHAT IS KNOWN: SLCO1B1 polymorphisms have been reported to affect the responses to statin therapy. However, the association of these polymorphisms and lipid lowering responses has been inconsistent. OBJECTIVE: To investigate the effect of SLCO1B1 c.388A>G, c.521T>C and g.89595T>C polymorphisms on the lipid-lowering response to simvastatin therapy in Thai hypercholesterolaemic patients. METHODS: Three hundred and 91 hypercholesterolaemic patients in Southern Thailand were enrolled and treated with simvastatin 20 or 40 mg per day. Among them, 191 and 200 patients were treated for 3 and 12 months, respectively. Serum lipids were measured before and after the treatment. SLCO1B1 c.388A>G, c.521T>C and g.89595T>C polymorphisms were analysed using polymerase chain reaction-high resolution melting (PCR-HRM). RESULTS: The allele frequencies of the SLCO1B1 c.388A>G, c.521T>C and g.89595T>C polymorphisms in Thai hypercholesterolaemic patients were 74.9%, 11.8% and 37.2%, respectively. After treatment with 20-40 mg simvastatin daily for 3 and 12 months, TC, TG and LDL-C concentrations were significantly lower than at baseline (P < .05). However, there was no a significant change in serum HDL-C after simvastatin treatment for 3 and 12 months (P > .05). Moreover, there was no association between SLCO1B1 c.388A>G, c.521T>C and g.89595T>C polymorphisms and lipid-lowering response to 3 and 12 months of either 20 or 40 mg/day simvastatin treatment. WHAT IS NEW AND CONCLUSION: SLCO1B1 c.388A>G, c.521T>C and g.89595T>C polymorphisms may not be useful as genetic markers of lipid-lowering response to simvastatin therapy in Thai hypercholesterolaemic patients.

PMID- 29575101 TI - Adherent agarose mold cultures: An in vitro platform for multi-factorial assessment of passaged chondrocyte redifferentiation. AB - Generating the best possible bioengineered cartilage from passaged chondrocytes requires culture condition optimization. In this study, the use of adherent agarose mold (adAM) cultures to support redifferentiation of passaged twice (P2) chondrocytes and serve as a scalable platform to assess the effect of growth factor combinations on proteoglycan accumulation by cells was examined. By 2 days in adAM culture, bovine P2 cells were partially redifferentiated as demonstrated by regression of actin-based dedifferentiation signalling and fibroblast matrix and contractile gene expression. By day 10, aggrecan and type II collagen gene expression were significantly increased in adAM cultured cells. At day 20, a continuous layer of cartilage tissue was observed. There was no evidence of tissue contraction by P2 cells in adAM cultures. The matrix properties of the resultant tissue as well as proteoglycan 4 (PRG4) secreted by the cells were dependent on the initial cell seeding density. AdAM cultures were scalable and culture within small 3 mm diameter adAM allowed for multi-factorial assessment of growth factors on proteoglycan accumulation by human P2 chondrocytes. Although there was a patient specific response in proteoglycan accumulation to the various cocktail combinations, the cocktail consisting of 2 ng/ml TGFbeta1, 10 ng/ml FGF2, and 250 ng/ml FGF18 resulted in a consistent increase in alcian blue tissue staining. Additional studies will be required to identify the optimal conditions to bioengineer articular cartilage tissue for clinical use. However, the results to date suggest that adAM cultures may be suitable to use for high throughput assessment. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

PMID- 29575105 TI - Method for the estimation of genetic merit of animals with uncertain paternity under Bayesian inference. AB - The use of controlled mating or artificial insemination is impracticable in the case of large herds, mainly because of labour costs and the need to delimit areas during the breeding period. However, the exclusion of information from animals with uncertain paternity reduces genetic progress. The objectives of this study were as follows: (i) propose an iterative empirical Bayesian procedure to implement the hierarchical animal model (ITER); (ii) calculate the posterior probabilities of paternity by the maximum likelihood method following the concepts; (iii) compare an average numerator relationship matrix (ANRM), Bayesian hierarchical (HIER) models and ITER. Records of Nellore animals born between 1984 and 2006 from the zootechnical archive of Agropecuaria Jacarezinho Ltda were used. For data consistency, records of contemporary groups (CGs) with fewer than three animals and animals whose records were 3.5 standard deviations above or below the mean of their CG were eliminated. After editing the data, 62,212 animals in the file and 12,876 animals in pedigree file were maintained, respectively. Spearman and Pearson correlations between the posterior mean of the genetic effects of animals were calculated to compare the ranking of animals for selection. Simulated data were used to confirm the veracity of the model. The correlations between ITER and HIER and between ITER and ANRM were similar evaluating different files, which decreased at the same proportion when only high ranked animals were evaluated. In conclusion, the model proposed herein is a suitable computational alternative to improve the prediction of breeding values of animals in genetic evaluations using large databases, including animals with uncertain paternity. PMID- 29575106 TI - Antifungal treatment in haematological and oncological patients: Need for quality assessment in routine care. AB - Invasive fungal infections in haematological and oncological patients have a major impact on morbidity, mortality and treatment costs. Therefore, rational use of antifungal agents is important for optimal patient care and resource use. The study's objective was to analyse antifungal usage in a German tertiary teaching hospital, department of haematology and oncology, to evaluate quality of antifungal treatment and to assess the need for an antifungal stewardship programme. This retrospective observational study included patients >=18 years receiving systemic antifungals for prophylaxis or therapy of invasive fungal infection between January and June 2016. Appropriateness of antifungal prescriptions was evaluated in accordance with guidelines of the German Society of Haematology and Oncology (DGHO) and drug labelling. In total, 104/1278 (8.1%) patients received antifungals. One hundred seventy-one antifungals were prescribed: 48 for prophylaxis, 104 for empirical and 19 for targeted therapy. In 127 (74.3%) prescriptions, indication was appropriate, and in 132 (77.2%), choice of drug. Antifungals were correctly dosed in 131 prescriptions (76.6%). Thirty four antifungals (20.0%) were co-administrated with interacting drugs (5 mild to moderate, 29 severe interactions). Results of this analysis demonstrate that use of systemic antifungals in routine care differs in a substantial number of patients from guideline and labelling recommendations. To optimise antifungal use, the implementation of antifungal stewardship programmes seems to be justified. PMID- 29575107 TI - Nonfullerene Tandem Organic Solar Cells with High Performance of 14.11. AB - Fabricating solar cells with tandem structure is an efficient way to broaden the photon response range without further increasing the thermalization loss in the system. In this work, a tandem organic solar cell (TOSC) based on highly efficient nonfullerene acceptors (NFAs) with series connection type is demonstrated. To meet the different demands of front and rear sub-cells, two NFAs named F-M and NOBDT with a whole absorption range from 300 to 900 nm are designed, when blended with wide bandgap polymer poly[(2,6-(4,8-bis(5-(2 ethylhexyl)thiophen-2-yl)-benzo[1,2-b:4,5-b']dithiophene))-alt-(5,5-(1',3'-di-2 thienyl-5',7'-bis(2-ethylhexyl)benzo[1',2'-c:4',5'-c']dithiophene-4,8-dione))] (PBDB-T) and narrow bandgap polymer PTB7-Th, respectively, the PBDB-T: F-M system exhibits a high Voc of 0.98 V and the PTB7-Th: NOBDT system shows a remarkable Jsc of 19.16 mA cm-2 , which demonstrate their potential in the TOSCs. With the guidance of optical simulation, by systematically optimizing the thickness of each layer in the TOSC, an outstanding power conversion efficiency of 14.11%, with a Voc of 1.71 V, a Jsc of 11.72 mA cm-2 , and a satisfactory fill factor of 0.70 is achieved; this result is one of the top efficiencies reported to date in the field of organic solar cells. PMID- 29575108 TI - Coumarin/BODIPY Hybridisation for Ratiometric Sensing of Intracellular Polarity Oscillation. AB - With different polarity responses, coumarin and 4,4-difluoro-4-bora-3a,4a-diaza-s indacene (BODIPY) were hybridised to construct polarity fluorescent sensors, CBDP and iso-CBDP, to overcome the disadvantages of solvatochromic sensors in ratiometric polarity sensing. Only CBDP displayed an emission ratio (ICou /IBDP , coumarin to BODIPY emissions) that increased with an exponential dependence on medium relative permittivity over a wide polarity range (epsilonr <57.9). This sensing ability of CBDP was not affected by medium pH; viscosity; and most intracellular species, especially reactive oxygen, nitrogen, and sulfur species. Apart from local cytoplasmic polarity quantification through lambda imaging, CBDP enables real-time ratiometric imaging for intracellular polarity oscillation induced by oxidative stimulation. Ratiometric polarity flow cytometry was developed, for the first time, with CBDP, which demonstrated that a high concentration H2 O2 induced cytoplasmic polarity enhancement, whereas pre incubation with N-acetyl-l-cysteine inhibited this effect. PMID- 29575109 TI - Patterns of carer distress over time in mild dementia. AB - OBJECTIVE: To study the level of carer reported distress in mild dementia, over a 3-year period. METHODS: This study is part of the Norwegian DemVest-study and utilises data from carers of people with mild dementia (n = 223). Those diagnosed with dementia with Lewy bodies (DLB, n = 63) and Alzheimer's disease (AD, n = 97) were included together with other dementia types (n = 63). The Relatives' Stress Scale was used to assess the level of reported distress in carers. Descriptive and a linear mixed effects models including diagnosis, time, and the interaction between time and diagnosis were performed. RESULTS: Carer distress in mild dementia increased significantly over time (P = 0.011), particularly from baseline until 2 (P = 0.001) years follow-up. Carer distress in people caring for those with AD increased significantly, from baseline until 2 (P = 0.047) and 3 (P = 0.019) years follow-up. Distress in carers of people with DLB was high at baseline and remained relatively stable across the 3-year period. However, admission to a nursing home during the first year of follow-up was associated with a significantly lower reported carer distress in those caring for a person with DLB (P = 0.002), compared with those caring for a person with DLB living at home. CONCLUSION: Being a carer to a person with mild dementia is associated with increasing distress. However, the burden of distress changes with the diagnosis, time, and situation, which highlights the dynamic nature of the caring role. Findings have important implications for health services for people diagnosed with mild dementia and their carers. PMID- 29575110 TI - Percutaneous coronary intervention: 2017 in review.

PMID- 29575111 TI - Epilobium spp: Pharmacology and Phytochemistry. AB - The Epilobium species and their extracts are very popular in folk medicine, for a wide range of applications. The purpose of this review is the analysis of the pharmacological properties of Epilobium spp, considering whether their effects (e.g., anti-inflammatory, antioxidant, antitumor, antimicrobial, analgesic, and antiandrogenic) could rationally justify the use of Epilobium as a treatment of numerous diseases. Even if numerous preclinical studies have been reported, randomized controlled clinical trials (for the evaluation of safety and efficacy), and eventually cost-effectiveness studies (to estimate the long-term cumulative costs), are still needed to confirm the usefulness of these medicinal plants in human diseases. PMID- 29575112 TI - The what, when, and why of human prostate cancer xenografts. AB - BACKGROUND: Presently, ~85 serially transplantable human prostate cancer xenografts spanning the phenotypic, epigenetic, and genetic heterogeneity seen clinically are available in a variety of laboratories throughout the world. If distributed to the prostate cancer research community, these can provide an experimental platform for resolving the specificity versus generalizability of basic cancer biology principles (eg, credentialing of therapeutic molecular targets) and for validating translational approaches for prevention, diagnosis, and therapy. Thus, there is an urgent need to distribute the already established serially transplantable human prostate cancer xenografts and to develop robust methods for establishing new ones. METHODS: To accelerate the development of such additional xenografts, particularly from patients treated with the newer standard of care agents (ie, abiraterone, enzalutamide, cabazitaxel, alpharadin, etc), a historic review of the field will be presented. RESULTS: Over the last 50 years, multiple groups throughout the world have developed methods for the successful establishment of serially transplantable human prostate cancer xenografts using a variety of immune deficient mice. These are summarized chronologically. CONCLUSIONS AND FUTURE: With the ever growing appreciation of the value of personalized medicine (aka precision medicine), methods need to be developed that allow efficient and timely growth of primary patient derived prostate cancer xenografts (PDXs), which can be used as "avatars" for defining optimal therapy for that specific patient. Such development should be based upon the leads obtained from the successful establishment of serially transplantable prostate cancer xenografts described in this review. PMID- 29575113 TI - Renal volume assessed by magnetic resonance imaging volumetry correlates with renal function in living kidney donors pre- and postdonation: a retrospective cohort study. AB - Renal function of potential living kidney donors is routinely assessed with scintigraphy. Kidney anatomy is evaluated by imaging techniques such as magnetic resonance imaging (MRI). We evaluated if a MRI-based renal volumetry is a good predictor of kidney function pre- and postdonation. We retrospectively analyzed the renal volume (RV) in a MRI of 100 living kidney donors. RV was correlated with the tubular excretion rate (TER) of MAG3-scintigraphy, a measured creatinine clearance (CrCl), and the estimated glomerular filtration rate (eGFR) by Cockcroft-Gault (CG), CKD-EPI, and modification of diet in renal disease (MDRD) formula pre- and postdonation during a follow-up of 3 years. RV correlated significantly with the TER (total: r = 0.6735, P < 0.0001). Correlation between RV and renal function was the highest for eGFR by CG (r = 0.5595, P < 0.0001), in comparison with CrCl, MDRD-GFR, and CKD-EPI-GFR predonation. RV significantly correlated with CG-GFR postdonation and predicted CG-GFR until 3 years after donation. MRI renal volumetry might be an alternative technique for the evaluation of split renal function and prediction of renal function postdonation in living kidney donors. PMID- 29575114 TI - American council on ECP (ACE): Why now? AB - Stimulated by the scientific progress in deciphering the principal elements contributing to the clinical efficacy of extracorporeal photochemotherapy (ECP), the American Council on ECP (ACE) was formed, under the auspices of the American Society for Apheresis (ASFA), to develop a field-guiding Consensus Report. ACE is composed of thirty nationally recognized ECP experts, clinically spanning cancer, transplantation, and autoimmunity and scientifically bridging immunology, bioengineering, and hematology. The two-day meeting took place in Manhattan, April 13-14, 2017, and unanimous consensus on nine pivotal points is herein reported. (1) ECP's clinical evolution must now enter a scientifically driven phase. (2) ECP is currently a bidirectional therapy, both immunizing and tolerizing simultaneously, via a single one-size-fits-all inflexible medical device. (3) To preclude inadvertent tolerization in the cancer setting, or immunization in the transplant rejection setting, polarization of ECP to either immunization or tolerization mode to match the clinical need is now possible and necessary. (4) Cutaneous T cell lymphoma (CTCL) is a genetically driven cancer, whose response to ECP is due to enhanced anti-cancer immunity. (5) ECP is a dendritic antigen-presenting cell (DC) based therapy. (6) ECP's efficacy can now be tested in a broad array of cancers. (7) ECP's capacity to tolerize to allotransplants via processing of donor leukocytes merits expedited human investigation. (8) UVA-8-MOP-impacted ECP-induced DC are potent antigen-specific tolerizing agents, while UVA-8-MOP(8-Methoxypsoralen)-spared ECP-induced DC are potent antigen-specific immunizing agents. (9) Six pilot clinical trial areas (CTCL, graft-vs.-host disease, ovarian carcinoma, anti-graft cytotoxic antibodies, pemphigus vulgaris, and haplotype mismatched stem cell transplants) are advised. ACE will be an ongoing advisory group for the field, with the goal of overseeing coordinated clinical and fundamental research efforts. PMID- 29575115 TI - Lipid profile and incidence of atrial fibrillation: A prospective cohort study in China. AB - BACKGROUND: The association between dyslipidemia, a major risk factor for cardiovascular diseases, and atrial fibrillation (AF) is not clear because of limited evidence. HYPOTHESIS: Dyslipidemia may be associated with increased risk of AF in a Chinese population. METHODS: A total of 88 785 participants free from AF at baseline (2006-2007) were identified from the Kailuan Study. Fasting levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglycerides (TG) were measured at baseline using standard procedures. The study population was stratified based on quartiles of lipid profile. Incident AF was ascertained from electrocardiograms at biennial follow-up visits (2008-2015). The associations between incident AF and the different lipid parameters (TC, LDL-C, HDL-C, and TG) were assessed by Cox proportional hazards regression analysis. RESULTS: Over a mean follow-up period of 7.12 years, 328 subjects developed AF. Higher TC (hazard ratio [HR]: 0.60, 95% confidence interval [CI]: 0.43-0.84) and LDL-C (HR: 0.60, 95% CI: 0.43 0.83) levels were inversely associated with incident AF after multivariable adjustment. HDL-C and TG levels showed no association with newly developed AF. The results remained consistent after exclusion of individuals with myocardial infarction or cerebral infarction, or those on lipid-lowering therapy. Both TC/HDL-C and LDL-C/HDL-C ratios were inversely associated with risk of AF (per unit increment, HR: 0.88, 95% CI: 0.79-0.98 and HR: 0.77, 95% CI: 0.66-0.91, respectively). CONCLUSIONS: TC and LDL-C levels were inversely associated with incident AF, whereas no significant association of AF with HDL-C or TG levels was observed. PMID- 29575116 TI - Making the best use of data not created for research. PMID- 29575117 TI - Postnatal maturation of microglia is associated with alternative activation and activated TGFbeta signaling. AB - Microglia are involved in a widespread set of physiological and pathological processes and further play important roles during neurodevelopmental events. Postnatal maturation of microglia has been associated with the establishment of microglia-specific gene expression patterns. The mechanisms governing microglia maturation are only partially understood but Tgfbeta1 has been suggested to be one important mediator. In the present study, we demonstrate that early postnatal microglia maturation is associated with alternative microglia activation, increased engulfment of apoptotic cells as well as activated microglial Tgfbeta signaling. Interestingly, microglial Tgfbeta signaling preceded the induction of the microglia-specific gene expression indicating the importance of Tgfbeta1 for postnatal microglia maturation. Moreover, we provide evidence that Tgfbeta1 is expressed by neurons in postnatal and adult brains defining neuron-microglia communication via Tgfbeta1 as an important event. Finally, we introduce the recently identified microglia marker Tmem119 as a direct Tgfbeta1-Smad2 target gene. Taken together, the data presented here further increase the understanding of Tgfbeta1-mediated effects in microglia and place emphasis on the importance of Tgfbeta1 for microglia maturation and maintenance.

AB - To achieve high-energy and stable aqueous rechargeable batteries, state-of-the art of anode materials are needed. Bismuth (Bi) has recently emerged as an attractive anode material due to its highly reversible redox reaction and suitable negative operating working window. However, the capacity and durability of currently reported Bi anodes are still far from satisfactory. Here, an in situ activation strategy is reported to prepare a 3D porous high-density Bi nanoparticles/carbon architecture (P-Bi-C) as an efficient anode for nickel bismuth batteries. Taking advantages of the fast channels for charge transfer and ion diffusion, enhanced wettability, and accessible surface area, the highly loaded P-Bi-C electrode delivers a remarkable capacity of 2.11 mA h cm-2 as well as high rate capability (1.19 mA h cm-2 at 120 mA cm-2 ). To highlight, a robust aqueous rechargeable Ni//Bi battery based on the P-Bi-C anode is first constructed, achieving decent capacity (141 mA h g-1 ), impressive durability (94% capacity retention after 5000 cycles), and admirable energy density (16.9 mW h cm-3 ). This work paves the way for designing superfast nickel-bismuth batteries with high energy and long-life and may inspire new development for aqueous rechargeable batteries. PMID- 29575120 TI - Determination of Normal Skin Elasticity by Using Real-time Shear Wave Elastography. AB - OBJECTIVES: To define the reference ranges of normal skin elasticity measurements associated with shear wave elastography (SWE) in healthy volunteers and analyze the factors that may affect SWE. METHODS: Mean skin thickness and elastic modulus values from 90 healthy volunteers were evaluated with B-mode ultrasonography and SWE in the right fingers and forearms, anterior chest, and abdominal walls. Reference ranges of normal skin elasticity were calculated by using lower and upper limits at the 2.5th and 97.5th percentiles. To investigate the effects of potential factors (site, sex, age, body mass index, and skin thickness) on skin elasticity measurements, a 1-way analysis of variance, the Student t test, and the Pearson correlation test were performed. RESULTS: Skin elasticity was significantly different at different sites (P < .05). Mean elastic modulus values were 30.3 kPa for the finger, 14.8 kPa for the forearm, 17.8 kPa for the chest wall, and 9.5 kPa for the abdominal wall, and reference ranges of normal skin elasticity were 12.1 to 48.4kPa for the finger, 3.5 to 26.0 kPa for the forearm, 6.6 to 28.9 kPa for the chest wall, and 3.5 to 15.5 kPa for the abdominal wall. Our study revealed that men had higher skin elasticity measurements than women (P < .05), and they were more elevated in participants aged 20 to 50 years than in the other groups at the finger (P < .05). The body mass index and skin thickness had a negligible impact on skin elasticity measurements (P > .05). CONCLUSIONS: This study revealed that the site, sex, and age should be taken into account when determining the reference ranges of normal skin elasticity by skin elasticity measurements. PMID- 29575121 TI - Manuka honey and methylglyoxal increase the sensitivity of Staphylococcus aureus to linezolid. AB - : The continued emergence and global spread of bacterial antibiotic resistance has fuelled the search for novel antimicrobial agents and resistance-modifying compounds. Manuka honey has both antimicrobial properties and the ability to increase the efficacy of FDA-approved antibiotic drugs. Compared to other types of honey, manuka honey contains elevated levels of methylglyoxal (MGO), a small molecule that contributes to its antibacterial activity. Manuka honey has shown particular promise for the treatment of antibiotic-resistant Gram-positive organisms such as methicillin-resistant Staphylococcus aureus. Linezolid is an oxazolidinone antibiotic used in the treatment of infections caused by a range of Gram-positive pathogens. Here, we demonstrate that manuka honey, as well as MGO in isolation, increases the sensitivity of S. aureus to linezolid in both agar diffusion and broth microdilution assays. This synergistic interaction is mediated in part by increased intracellular accumulation of linezolid in the presence of MGO. SIGNIFICANCE AND IMPACT OF THE STUDY: Manuka honey is widely recognized for its antimicrobial activity. Our study adds to the growing body of evidence that manuka honey and its active ingredient, methylglyoxal (MGO), can also function as antibiotic adjuvants. In this study, we provide the first report of synergy between MGO and linezolid against Staphylococcus aureus. Both manuka honey and purified MGO significantly increased the sensitivity of S. aureus to linezolid. PMID- 29575123 TI - First Japanese case of atypical Spitz tumor exhibiting ROS1 rearrangement.

AB - A Pd/(R)-BINAP-catalyzed enantioselective benzylic sulfonation of diarylmethyl carbonates with sodium sulfinates proceeds to deliver the corresponding chiral diarylmethyl sulfones in good yields with high enantioselectivity. The reaction occurs in a dynamic kinetic asymmetric transformation (DYKAT) manner and thus provides convergent access to optically active benzylic sulfones from racemic secondary benzylic carbonates. Additionally, the addition of H2 O is found to be critical for high enantioselectivity.

AB - Myocardial contractile dysfunction is associated with an increase in mitochondrial fission in patients with diabetes. However, whether mitochondrial fission directly promotes diabetes-induced cardiac dysfunction is still unknown. Melatonin exerts a substantial influence on the regulation of mitochondrial fission/fusion. This study investigated whether melatonin protects against diabetes-induced cardiac dysfunction via regulation of mitochondrial fission/fusion and explored its underlying mechanisms. Here, we show that melatonin prevented diabetes-induced cardiac dysfunction by inhibiting dynamin related protein 1 (Drp1)-mediated mitochondrial fission. Melatonin treatment decreased Drp1 expression, inhibited mitochondrial fragmentation, suppressed oxidative stress, reduced cardiomyocyte apoptosis, improved mitochondrial function and cardiac function in streptozotocin (STZ)-induced diabetic mice, but not in SIRT1-/- diabetic mice. In high glucose-exposed H9c2 cells, melatonin treatment increased the expression of SIRT1 and PGC-1alpha and inhibited Drp1 mediated mitochondrial fission and mitochondria-derived superoxide production. In contrast, SIRT1 or PGC-1alpha siRNA knockdown blunted the inhibitory effects of melatonin on Drp1 expression and mitochondrial fission. These data indicated that melatonin exerted its cardioprotective effects by reducing Drp1-mediated mitochondrial fission in a SIRT1/PGC-1alpha-dependent manner. Moreover, chromatin immunoprecipitation analysis revealed that PGC-1alpha directly regulated the expression of Drp1 by binding to its promoter. Inhibition of mitochondrial fission with Drp1 inhibitor mdivi-1 suppressed oxidative stress, alleviated mitochondrial dysfunction and cardiac dysfunction in diabetic mice. These findings show that melatonin attenuates the development of diabetes-induced cardiac dysfunction by preventing mitochondrial fission through SIRT1-PGC1alpha pathway, which negatively regulates the expression of Drp1 directly. Inhibition of mitochondrial fission may be a potential target for delaying cardiac complications in patients with diabetes. PMID- 29575125 TI - A unified hierarchical oscillatory network model of head direction cells, spatially periodic cells, and place cells. AB - Spatial cells in the hippocampal complex play a pivotal role in the navigation of an animal. Exact neural principles behind these spatial cell responses have not been completely unraveled yet. Here we present two models for spatial cells, namely the Velocity Driven Oscillatory Network (VDON) and Locomotor Driven Oscillatory Network. Both models have basically three stages in common such as direction encoding stage, path integration (PI) stage, and a stage of unsupervised learning of PI values. In the first model, the following three stages are implemented: head direction layer, frequency modulation by a layer of oscillatory neurons, and an unsupervised stage that extracts the principal components from the oscillator outputs. In the second model, a refined version of the first model, the stages are extraction of velocity representation from the locomotor input, frequency modulation by a layer of oscillators, and two cascaded unsupervised stages consisting of the lateral anti-hebbian network. The principal component stage of VDON exhibits grid cell-like spatially periodic responses including hexagonal firing fields. Locomotor Driven Oscillatory Network shows the emergence of spatially periodic grid cells and periodically active border-like cells in its lower layer; place cell responses are found in its higher layer. This model shows the inheritance of phase precession from grid cell to place cell in both one- and two-dimensional spaces. It also shows a novel result on the influence of locomotion rhythms on the grid cell activity. The study thus presents a comprehensive, unifying hierarchical model for hippocampal spatial cells.

PMID- 29575127 TI - Assessing the release of copper from nanocopper-treated and conventional copper treated lumber into marine waters II: Forms and bioavailability. AB - One application of nanocopper is as a wood-preserving pesticide in pressure treated lumber. Recent research has shown that pressure-treated lumber amended with micronized copper azole (MCA), which contains nanosized copper, releases copper under estuarine and marine conditions. The form of copper released (i.e., ionic, nanocopper [1-100 nm in size]) is not fully understood but will affect the bioavailability and toxicity of the metal. In the present study, multiple lines of evidence, including size fractionation, ion-selective electrode electrochemistry, comparative toxicity, and copper speciation were used to determine the form of copper released from lumber blocks and sawdust. The results of all lines of evidence supported the hypothesis that ionic copper was released from MCA lumber and sawdust, with little evidence that nanocopper was released. For example, copper concentrations in size fractionations of lumber block aqueous leachates including unfiltered, 0.1 MUm, and 3 kDa were not significantly different, suggesting that the form of copper released was in the size range operationally defined as dissolved. These results correlated with the ion selective electrode data which detects only ionic copper. In addition, comparative toxicity testing resulted in a narrow range of median lethal concentrations (221-257 MUg/L) for MCA lumber blocks and CuSO4 . We conclude that ionic copper was released from the nanocopper pressure-treated lumber under estuarine and marine conditions. Environ Toxicol Chem 2018;37:1969-1979.

PMID- 29575129 TI - The Generation of Diazo Compounds in Continuous-Flow. AB - Toxic, cancerogenic and explosive-these attributes are typically associated with diazo compounds. Nonetheless, diazo compounds are nowadays a highly demanded class of reagents for organic synthesis, yet the concerns with regards to safe and scalable transformations of these compounds are still exceptionally high. Lately, the research area of the continuous-flow synthesis of diazo compounds attracted significant interest and a whole variety of protocols for their "on demand" preparation have been realized to date. This concept article focuses on the recent developments using continuous-flow technologies to access diazo compounds; thus minimizing risks and hazards when working with this particular class of compounds. In this article we discuss these concepts and highlight different pre-requisites to access and to perform downstream functionalization reaction. PMID- 29575130 TI - Mitochondrial inhibitory factor protein 1 attenuates coupling factor 6-induced aging signal. AB - Coupling factor 6 (CF6) forces a counter-clockwise rotation of plasma membrane F1 Fo complex, resulting in proton import and accelerated aging. Inhibitory factor peptide 1 (IF1) suppresses a unidirectional counter-clockwise rotation of F1 Fo complex without affecting ATP synthesis. We tested the hypothesis that IF1 may attenuate CF6-induced aging signaling in CF6-overexpressing transgenic (TG) cells. In IF1-GFP overexpressing wild type (WT) cells, the diffuse peripheral staining of tubular mitochondria was observed with a dense widely distributed network around the nucleus. In TG cells, however, the only peri-nuclear network of fragmented mitochondria was observed at 24 h, but it was developed to a widely distributed mitochondrial network of tubular mitochondria at 72 h. TG cells displayed aging hallmarks of telomere attrition, epigenetic alterations, defective proteostasis, and genomic instability with a decrease in emerin and lamin and loss of heterochromatin. IF1 induction rescued TG cells from telomere attrition, expression of genomic instability with the increase in emerin and lamin, and that of epigenetic alterations with recovery of heterochromatin. In defective proteostasis, IF1 induction restored a potent peri-nuclear staining of autolysosomes compared with the baseline weak staining. The decrease in Atg7 was restored, whereas the increase in P62 was abolished. We conclude that genetic disruption of proton signals by IF1 induction suppressed CF6-induced expression of aging hallmarks such as telomere attrition, epigenetic alterations, defective proteostasis, and genomic instability. Given the widespread biological actions of CF6, the physiological and pathological actions of IF1 may be complex. PMID- 29575131 TI - Anticoagulation, bleeding, and clotting at donor plasmapheresis. AB - This article is based on a question of a colleague from North America how coagulation could be triggered between a donor's arm and a fistula needle during plasma donation (synonymous with donor plasmapheresis). The technique of venipuncture and citrate anticoagulation are described. Uncommon and rare problems such as prolonged bleeding, scarring, and thrombosis in plasma donors are discussed. If venous puncture and citrate: blood flow ratio at 1:16 are correctly performed, however, there will be no anticoagulation abnormalities due to plasma donation. PMID- 29575132 TI - Complex formation dynamics of native and mutated pyrin's B30.2 domain with caspase-1. AB - Pyrin protein is the product of the MEFV gene, mutations in which cause manifestation of familial Mediterranean fever (FMF). Functions of pyrin are not completely clear. The secondary structure of the pyrin is represented with four domains and two motifs. Mutations p.M680I, p.M694V, p.M694I, p.K695R, p.V726A, and p.A744S, which are located in the B30.2 domain of pyrin protein, are responsible for manifestation of the most common and severe forms of FMF. All the domains and the motifs of pyrin, are directly or indirectly, involved in the protein-protein interaction with proteins of apoptosis and regulate the cascade of inflammatory reactions, which is impaired due to pyrin mutations. It is well known, that malfunction of the pyrin-caspase-1 complex is the main reason of inflammation during FMF. Complete tertiary structure of pyrin and the effects of mutations in it are experimentally not studied yet. The aim of this study was to identify possible effects of the abovementioned mutations in the B30.2 domain tertiary structure and to determine their potential consequences in formation of the B30.2-caspase-1 complex. Using in silico methods, it was found, that these mutations led to structural rearrangements in B30.2 domain tertiary structure, causing shifts of binding sites and altering the interaction energy between B30.2 and caspase-1. PMID- 29575133 TI - Gemcitabine induces apoptosis and autophagy via the AMPK/mTOR signaling pathway in pancreatic cancer cells. AB - Gemcitabine (GEM)-based chemotherapy is a commonly used treatment for pancreatic cancer. However, acquired drug resistance, a major problem in pancreatic cancer treatment, causes a reduction in the survival rate of patients with cancer. In this study, we attempted to reveal the molecular mechanism of GEM resistance. Our data showed that GEM treatment inhibits cell growth, induces apoptosis, and activates autophagy via the AMP-activated protein kinase (AMPK) pathway. The combination of GEM treatment and AMPK knockdown resulted in a dramatic increase of apoptosis and inhibition of autophagy. Additionally, inhibition of mammalian target of Rapamycin induced autophagy. Our findings show the potential therapeutic implications of the combined treatment with GEM and AMPK inhibitors for pancreatic cancer. PMID- 29575134 TI - Glucose alert system improves health professional responses to adverse glycaemia and reduces the number of hyperglycaemic episodes in non-critical care inpatients. AB - AIM: To investigate the effect of a novel glucose alert system, comprising the Melbourne Glucose Alert Pathway and glucose-alert-capable networked blood glucose meters, on nursing and hospital medical officer responses to adverse glycaemia. METHODS: A prospective, pre- and post-observational study was undertaken in non critical care wards of a tertiary hospital over 4 months (n=148 or 660 patient days). The intervention consisted of two components designed to promote a consistent staff response to blood glucose measurements: (1) a clinical escalation pathway, the Melbourne Glucose Alert Pathway, and (2) networked blood glucose meters, which provide a visual alert for out-of-range blood glucose measurement. All consecutive inpatients with diabetes were assessed for diabetes management and capillary blood glucose. The primary outcome was documented nursing and medical staff action in response to episodes of adverse glycaemia (blood glucose >15 mmol/l or <4 mmol/l). Secondary outcomes consisted of glycaemic measures. RESULTS: In response to episodes of adverse glycaemia, nursing action increased (proportion with nursing action: 45% to 73%; P<0.001), and medical action increased (proportion with medical action: 49% to 67%; P=0.011) with the glucose alert system in place. Patient-days with hyperglycaemia (any blood glucose value >15 mmol/l: 24% vs 16%; P=0.012) and patient-days with mean blood glucose >15 mmol/l (7.4% vs 2.6%; P=0.005) decreased. There was no difference in hypoglycaemia incidence. CONCLUSIONS: Use of a novel glucose alert system improved health professional responses to adverse glycaemia and decreased hyperglycaemia in the hospital setting. PMID- 29575135 TI - Comparison of the Diagnostic Efficacy of Ultrasound-Guided Core Needle Biopsy With 18- Versus 20-Gauge Needles for Thyroid Nodules. AB - OBJECTIVES: To compare the diagnostic efficacy, complication rate, and core needle biopsy (CNB) specimen yield in 18- versus 20-gauge ultrasound (US)-guided CNB for diagnosis of thyroid nodules. METHODS: We included 81 consecutive thyroid nodules with US-guided biopsy by a 20-gauge core needle and 86 consecutive thyroid nodules with US-guided biopsy by an 18-gauge core needle during 2 years. The rate of inconclusive results, including nondiagnostic or atypia/follicular lesion of undetermined significance, was compared. The diagnostic performance for malignancy was assessed in nodules with a final diagnosis. The complication rate and CNB specimen yield were also compared. RESULTS: Eighteen-gauge CNB showed a lower rate of nondiagnostic results (1.2% versus 8.6%; P = .024) than 20-gauge CNB; however, the rates of atypia/follicular lesion of undetermined significance and inconclusive results were not significantly different between the groups (P > .05). In addition, 18-gauge CNB showed higher sensitivity (75.0% versus 66.7%), a higher negative predictive value (83.9% versus 75.9%), and higher accuracy (78.3% versus 74.4%) for detecting malignancy than 20-gauge CNB, although the results did not achieve statistical significance. No major complications occurred in either of the CNB groups. The 18-gauge needle group had significantly fewer CNBs and larger specimen diameters (P < .001). CONCLUSIONS: Core needle biopsy with an 18-gauge needle could be more effective for the diagnosis of thyroid nodules than CNB with a 20-gauge needle. PMID- 29575136 TI - Diagnosis of pneumocystis pneumonia in a 2-year-old King Charles Cavalier Spaniel using the polymerase chain reaction. AB - A 2-year-old, female spayed, King Charles Cavalier Spaniel was presented for evaluation of dyspnea, inappetence, and lethargy. Thoracic radiographs revealed a moderate diffuse interstitial lung pattern affecting the perihilar and caudodorsal lung fields, and an echocardiogram revealed severe pulmonary hypertension. A bronchoalveolar lavage (BAL) was performed, and cytology revealed mixed inflammation with cysts and trophozoites consistent with Pneumocystis. Pneumocystis infection was later confirmed with PCR. To the author's knowledge, this report represents the first case of canine pneumocystis pneumonia diagnosed antemortem with PCR from a BAL sample. Pneumocystis represents an important, but uncommon cause of afebrile pneumonia in immunosuppressed dogs. PMID- 29575137 TI - Preparation of canine C-reactive protein serum reference material: A feasibility study. AB - BACKGROUND: The availability of a species-specific reference material is essential for the harmonization of results obtained in different laboratories by different methods. OBJECTIVES: We describe the preparation of a canine C-reactive protein (cCRP) serum reference material containing purified cCRP stabilized in a serum matrix. The material can be used by manufacturers to assign values to their calibrator and control materials. METHODS: The serum matrix was obtained using blood collected from healthy dogs, stabilized and submitted for a delipidation process. The reference material was prepared by diluting purified cCRP in the serum matrix containing 1.0 mol/L HEPES buffer, 3.0 mmol/L calcium chloride, 80,000 kUI/L aprotinin, and 1.0 mmol/L benzamidine hydrochloride monohydrate at a pH of 7.2, and dispensing (0.5 mL) the matrix into vials that were then frozen. RESULTS: The pilot batch of 200 vials was shown to be homogeneous and stable after a stability study at various temperatures and over a total time of 110 days. The prepared material was submitted to an assignment value study. Eight laboratories from different European countries participated by using the same reagents for an immunoturbidimetric method adapted for different analyzers. The obtained cCRP concentration in the reference material was 78.5 mg/L with an expanded uncertainty (k = 2) of 4.2 mg/L. CONCLUSIONS: Canine C-reactive protein serum reference material has been produced that allows harmonization of results obtained by different methods and different laboratories, thus reducing the possibility of errors and misunderstandings.

PMID- 29575140 TI - Validation of a paraoxon-based method for measurement of paraoxonase (PON-1) activity and establishment of RIs in horses. AB - BACKGROUND: Paraoxonase-1 (PON-1) is an antioxidant compound that is considered a negative acute phase protein. No information on the analytic performance of the paraoxon method for measuring PON-1 in horse serum is available. OBJECTIVES: The aim of this study was to validate a paraoxon-based method to measure PON-1 in horses and to establish RIs in healthy horses and foals. METHODS: Horses and foals classified as healthy after physical examination and routine biochemistry were used in the study. Serum PON-1 activity was measured with an automated spectrophotometer and an enzymatic method validated in other species. After the analytic validation (precision, accuracy, interference studies), RIs were determined using the Reference Value Advisor software. The possible sex-, age-, and breed-related differences were statistically investigated. RESULTS: The healthy study population included 120 horses and 55 foals. The paraoxon-based method was precise (CVs < 4.0%) and accurate (P < .001 in linearity under dilution and spike-recovery testing) but was affected by interference from mild bilirubinemia, severe lipemia, and hemoglobinemia. The RIs recorded in the whole population were 38.1-80.8 U/mL. According to the Harris and Boyd test, it would be advisable to use separate RIs only for adult females and for Warmblood and Trotter adults. CONCLUSIONS: This study demonstrated that the analytic performances of the paraoxon-based method for measurement of PON-1 in horses are acceptable. The PON-1 activity is lower in horses than in other domestic species. These results may provide a basis for further studies designed to establish whether healthy and sick horses can be correctly classified by using the PON-1 assay. PMID- 29575142 TI - Plasma biochemistry RIs and age effect in European Strigiformes. AB - BACKGROUND: Blood biochemistry and hematology are essential in the laboratory diagnosis of disease. In Strigiformes, little information regarding reference values and influence of different preanalytic factors is available, while age is known to have an effect on some biochemistry analytes, especially in early life characterized by a rapid growth rate and increase in body mass. OBJECTIVE: The objective of this study was to determine baseline data for 29 blood biochemistry variables in 5 species of Iberian Strigiformes assigned to different age classes. METHODS: Healthy nocturnal birds living in wildlife health centers of Catalonia, Northeastern Spain were assigned to different age classes (chicks, juveniles, adults where possible and available) and their blood was collected and analyzed for different standard biochemistry variables. Species included Tawny owls, Little owls, Long-eared owls, Scop owls, and Barn owls. RESULTS: A total of 276 clinically healthy animals were sampled, including between 179 chicks, 52 juveniles, and 45 adults. The RIs of cholesterol, albumin, and osmolality were the only variables that did not show interspecific variability. Common trends between age class groups were observed in 4 species. Phosphorus and calcium concentrations and ALP activities decreased with increasing age, while concentrations of sodium and gamma-globulins tended to increase in the Strigidae family. Differences were concentrated in chicks and no differences were observed between juveniles and adults in any variable. CONCLUSIONS: Our results demonstrate the importance of defining biochemical RIs specific for certain age classes. PMID- 29575143 TI - Blood gas and serum biochemical RIs for healthy newborn Murrah buffaloes (Bubalus bubalis). AB - BACKGROUND: There is a lack of published work on RIs for newborn buffaloes. Establishing blood gas and serum biochemical RIs for newborn buffaloes is important for monitoring health. OBJECTIVES: This study establishes blood gas and serum biochemical RIs of newborn buffaloes. METHODS: Twenty-eight newborn buffaloes, 10-30 days old, were selected. Thirty blood biochemical variables were analyzed. The Anderson-Darling test was used to assess the normality of the distribution. The Dixon test and the Tukey test were used to identify outliers. The RI and 90% CI were determined using standard and robust methods and the Box Cox transformation. RESULTS: A total of 30 RIs for healthy buffalo calves have been reported in this study. RIs for blood gas variables were reported for pH, partial pressure of oxygen (pO2 ), partial pressure of carbon dioxide (pCO2 ), saturation of O2 (SO2 ), bicarbonate (cHCO3- ), base excess (BE), total carbon dioxide (ctCO2 ), and anion gap (AG). RIs for serum biochemical variables were reported for glucose (GLU), direct bilirubin (DB), total bilirubin (TB), AST, ALP, GGT, CK, LDH, creatinine (CREA), urea, cholesterol (CHOL), triglycerides (TG), Ca, P, Mg, Na, K, iCa, Cl, iron, total protein (TP), and albumin (ALB). CONCLUSIONS: This is the first reported study covering complete serum chemistry and blood gas RIs for healthy 1-month-old Murrah buffaloes. PMID- 29575144 TI - Combined and breed-specific RIs for hematologic, biochemical, and hormonal analytes in Chios and Florina adult rams. AB - BACKGROUND: Clinical pathology investigations are essential to evaluate the health status and practice management of ruminants. Appropriate and accurate RIs are required for the interpretation of laboratory results. Despite substantial phenotypic differences and management-related disparities between male and female sheep, RIs in rams are sparse and limited by small reference populations and outdated methods. OBJECTIVES: The purpose of this study was to establish RIs for hematologic, biochemical, and hormonal analytes in adult rams using controlled preanalytic and analytic procedures, and to investigate whether breed-dependent partitioning of RIs is required. METHODS: Reference individuals were selected by a direct a priori method. Blood was collected from 128 healthy adult rams representing 2 Greek breeds (64 Chios and 64 Florina). Hematologic analysis was performed on the Advia 120, while differential WBC counts were manually performed on Giemsa-stained blood smears. Flexor E, AVL 9180 Electrolyte Analyzer, and Immulite 1000 were used for biochemical and hormonal analyses, respectively. Combined and breed-specific RIs were calculated using nonparametric and robust methods, respectively. RESULTS: Five outliers were detected based on laboratory results. Partitioning of RIs, based on both statistical and nonstatistical criteria, was recommended for some of the analytes. CONCLUSIONS: The RIs are in some agreement with those in the literature. The observed differences may be attributed to preanalytic and analytic factors. The RIs determined in this study can be used as a guide for the interpretation of laboratory results in rams and can potentially be adopted by veterinary laboratories, provided that similar equipment and reagents are used.

PMID- 29575146 TI - Evaluation of inhibitors for development of a selective medium for isolation of Leptospira spp. from clinical samples. AB - : This study was conducted to develop a selective medium for the detection of Leptospira spp. in clinical samples. Serovars of Leptospira spp., environmental bacteria and the fungus from contaminated cultures of patients with suspected leptospirosis were inoculated into EMJH medium containing amphotericin B, 5 fluorouracil (5-FU), furazolidone and neomycin used singly or combined. Medium with 5-FU at the concentration of 200 MUg ml-1 did not show any inhibitory effect against the fungus, Gram-negative bacilli and any of the leptospira strains except serovar Pyrogenes. The highest concentration of neomycin and furazolidone that did not inhibit the growth of leptospires was 4 MUg ml-1 . All strains of Leptospira spp. grew on 5-FU (100 MUg ml-1 ) in combination with neomycin (4 MUg ml-1 ) and on 5-FU (100 MUg ml-1 ) in combination with furazolidone (4 MUg ml-1 ). The highest concentration of amphotericin B (500 MUg ml-1 ) that inhibited the growth of the fungus also inhibited the bacteria and most of serovars of Leptospira spp. The most effective antibiotic combinations that inhibited the majority of environmental bacteria growth without affecting leptospiral growth were EMJH with 5-FU (100 MUg ml-1 ) in combination with neomycin (4 MUg ml-1 ). In conclusion, these findings will help the development of new selective media to isolate leptospires. SIGNIFICANCE AND IMPACT OF THE STUDY: Leptospirosis is one of the most widespread zoonotic diseases in the world. Since certain serovars are often associated with the symptoms and severity of the disease, the isolation and identification of the leptospires usually permits the prediction of sources of infection. Attempts to isolate Leptospira spp. from clinical specimens are often frustrated by overgrowth of the slow-growing bacteria by more rapidly growing contaminants. In this study, we evaluated selective agents to develop a new selective medium to isolate leptospires. The results demonstrated that the association of drugs in concentrations that allowed the growth of leptospires is to be more effective in inhibiting bacterial contaminants.

AB - Organic field-effect transistors (OFETs) with impressively high hole mobilities over 10 cm2 V-1 s-1 and electron mobilities over 1 cm2 V-1 s-1 have been reported in the past few years. However, significant non-ideal electrical characteristics, e.g., voltage-dependent mobilities, have been widely observed in both small molecule and polymer systems. This issue makes the accurate evaluation of the electrical performance impossible and also limits the practical applications of OFETs. Here, a semiconductor-unrelated, charge-trapping-induced non-ideality in OFETs is reported, and a revised model for the non-ideal transfer characteristics is provided. The trapping process can be directly observed using scanning Kelvin probe microscopy. It is found that such trapping-induced non-ideality exists in OFETs with different types of charge carriers (p-type or n-type), different types of dielectric materials (inorganic and organic) that contain different functional groups (?OH, ?NH2 , ?COOH, etc.). As fas as it is known, this is the first report for the non-ideal transport behaviors in OFETs caused by semiconductor independent charge trapping. This work reveals the significant role of dielectric charge trapping in the non-ideal transistor characteristics and also provides guidelines for device engineering toward ideal OFETs. PMID- 29575149 TI - Exercise decreases CLK2 in the liver of obese mice and prevents hepatic fat accumulation. AB - The accumulation of fatty acids in the liver associated with obesity condition is also known as nonalcoholic fatty liver disease (NAFLD). The impaired fat oxidation in obesity condition leads to increased hepatic fat accumulation and increased metabolic syndrome risk. On the other hand, physical exercise has been demonstrated as a potent strategy in the prevention of NAFLD. Also, these beneficial effects of exercise occur through different mechanisms. Recently, the Cdc2-like kinase (CLK2) protein was associated with the suppression of fatty acid oxidation and hepatic ketogenesis. Thus, obese animals demonstrated elevated levels of hepatic CLK2 and decreased fat acid oxidation. Here, we explored the effects of chronic physical exercise in the hepatic metabolism of obese mice. Swiss mice were distributed in Lean, Obese (fed with high-fat diet during 16 weeks) and Trained Obese group (fed with high-fat diet during 16 weeks and exercised (at 60% exhaustion velocity during 1 h/5 days/week) during 8 weeks. In our results, the obese animals showed insulin resistance, increased hepatic CLK2 content and increased hepatic fat accumulation compared to the Lean group. Otherwise, the chronic physical exercise improved insulin resistance state, prevented the increased CLK2 in the liver and attenuated hepatic fat accumulation. In summary, these data reveal a new protein involved in the prevention of hepatic fat accumulation after chronic physical exercise. More studies can evidence the negative role of CLK2 in the control of liver metabolism, contributing to the improvement of insulin resistance, obesity, and type 2 diabetes. PMID- 29575151 TI - Long non-coding RNA NEAT1 mediates the toxic of Parkinson's disease induced by MPTP/MPP+ via regulation of gene expression. AB - Parkinson's disease (PD) is a result of the loss of dopaminergic neurons in the substantia nigra and is expected to increase the economic burden on patients' families and societies. NEAT1, a long non-coding RNA, is known as a cancer related gene, however, the role of it in PD remains unclear. The aims of this study are to detect the NEAT1-mediated effects in PD and explore the mechanism of NEAT1 in PD. One group (n = 6) of C57BL/6 model mice were intraperitoneal injected with 1-Methyl-4-phenyl-2, 3, 6-tetrahydropyridine (MPTP), while another group (n = 6) was treated with saline and served as control. Human neuroblastoma cell line SH-SY5Y was pretreated with 1-Methyl-4-phenylpyridinium (MPP+). Cell viability and apoptosis, as well as gene expression with different treatments were examined. Up-regulated NEAT1 was found in MPTP-induced PD mice. Moreover, the NEAT1 expression was positively correlated with the concentration of MPP+. In SH-SY5Y cells stimulated by MPP+, NEAT1 knockdown dramatically promoted cell viability and suppressed cell apoptosis. Additionally, down-regulation of NEAT1 also decreased the ratio of Bax/Bcl-2, the activity of caspase-3, as well as the expression of alpha-synuclein. Moreover, alpha-synuclein overexpression could significantly reverse the increase in cell viability and the decrease in cell apoptosis induced by NEAT1 knockdown. The results suggested that the knockdown of NEAT1 will have a protective effect on MPTP-induced PD mice. The mechanism may be related to the dysregulation of alpha-synuclein.

AB - Detection of serum galactomannan (GM) and (1,3)-beta-d-glucan (BG) is considered useful for non-culture diagnosis of invasive pulmonary aspergillosis (IPA) in neutropenic patients. Only few studies evaluated these seromarkers in non neutropenic patients suspected of having IPA. The aim of this study was to evaluate both tests together with the Aspergillus fumigatus-specific serum IgG and IgA (IgAG) test for serological IPA diagnosis in non-neutropenic patients. Sera from 87 patients suspected of having IPA were retrospectively analysed. Patients were categorised into groups of proven IPA (n = 10), putative IPA (n = 31) and non-IPA colonisation (n = 46). When the GM, BG and IgAG assays were used for patients included in the study, the sensitivity/specificity/positive predictive value (PPV)/negative predictive value (NPV) were 48.8%/91.3%/83.3%/66.7%, 82.9%/73.9%/73.9%/82.9% and 75.6%/95.7%/93.9%/81.5%, respectively. Thus, the highest specificity and PPV were confirmed for the IgAG assay. Improvements in the sensitivity and NPV were achieved by "at least one positive" analysis with the GM and BG assays, with the sensitivity/specificity/PPV/NPV values being 85.0%/69.6%/71.4%/84.2%. Nevertheless, the highest sensitivity and NPV were achieved by the "at least one positive" analysis combining the GM, BG and IgAG tests (97.6% and 96.8%, respectively). The involvement of the IgAG assay could improve IPA diagnosis in non-neutropenic patients by increasing the sensitivity and NPV when combined with the GM or BG assays. Furthermore, improvement was achieved by combining the GM, BG and IgAG assays using the "at least one positive test" strategy, especially if doubt exists.

AB - Little is known about the release of metal engineered nanomaterials (ENMs) from consumer goods, including lumber treated with micronized copper. Micronized copper is a recent form of antifouling wood preservative containing nanosized copper particles for use in pressure-treated lumber. The present study investigated the concentrations released and the release rate of total copper over the course of 133 d under freshwater, estuarine, and marine salinity conditions (0, 1, 10, and 300/00) for several commercially available pressure treated lumbers: micronized copper azole (MCA) at 0.96 and 2.4 kg/m3 , alkaline copper quaternary (ACQ) at 0.30 and 9.6 kg/m3 , and chromated copper arsenate (CCA) at 40 kg/m3 . Lumber was tested as blocks and as sawdust. Overall, copper was released from all treated lumber samples. Under leaching conditions, total release ranged from 2 to 55% of the measured copper originally in the lumber, with release rate constants from the blocks of 0.03 to 2.71 (units per day). Generally, measured release and modeled equilibrium concentrations were significantly higher in the estuarine conditions compared with freshwater or marine salinities, whereas rate constants showed very limited differences between salinities. Furthermore, organic carbon was released during the leaching and demonstrated a significant relationship with released copper concentrations as a function of salinity. The results indicate that copper is released into estuarine/marine waters from multiple wood treatments including lumber amended with nanoparticle-sized copper.

PMID- 29575153 TI - Validation of the systematic scoring of immunohistochemically stained tumour tissue microarrays using QuPath digital image analysis. AB - AIMS: Output from biomarker studies involving immunohistochemistry applied to tissue microarrays (TMA) is limited by the lack of an efficient and reproducible scoring methodology. In this study, we examine the functionality and reproducibility of biomarker scoring using the new, open-source, digital image analysis software, QuPath. METHODS AND RESULTS: Three different reviewers, with varying experience of digital pathology and image analysis, applied an agreed QuPath scoring methodology to CD3 and p53 immunohistochemically stained TMAs from a colon cancer cohort (n = 661). Manual assessment was conducted by one reviewer for CD3. Survival analyses were conducted and intra- and interobserver reproducibility assessed. Median raw scores differed significantly between reviewers, but this had little impact on subsequent analyses. Lower CD3 scores were detected in cases who died from colorectal cancer compared to control cases, and this finding was significant for all three reviewers (P-value range = 0.002 0.02). Higher median p53 scores were generated among cases who died from colorectal cancer compared with controls (P-value range = 0.04-0.12). The ability to dichomotise cases into high versus low expression of CD3 and p53 showed excellent agreement between all three reviewers (kappa score range = 0.82-0.93). All three reviewers produced dichotomised expression scores that resulted in very similar hazard ratios for colorectal cancer-specific survival for each biomarker. Results from manual and QuPath methods of CD3 scoring were comparable, but QuPath scoring revealed stronger prognostic stratification. CONCLUSIONS: Scoring of immunohistochemically stained tumour TMAs using QuPath is functional and reproducible, even among users of limited experience of digital pathology images, and more accurate than manual scoring. PMID- 29575154 TI - Escherichia coli transcription factor NusG binds to 70S ribosomes. AB - Transcription and translation are coupled processes in bacteria. A role of transcription elongation cofactor NusG in coupling has been suggested by in vitro structural studies. NMR revealed association of the NusG carboxy-terminal domain with S10 (NusE), implying a direct role for NusG as a bridge linking RNAP and the lead ribosome. Here we present the first in vitro and in vivo evidence of full length NusG association with mature 70S ribosomes. Binding did not require accessory factors in vitro. Mutating the NusG:S10 binding interface at NusG F165 or NusE M88 and D97 residues weakened NusG:S10 association in vivo and completely abolished it in vitro, supporting the specificity of this interaction. Mutations in the binding interface increased sensitivity to chloramphenicol. This phenotype was suppressed by rpoB*35, an RNAP mutation that reduces replisome-RNAP clashes. We propose that weakened NusG:S10 interaction leads to uncoupling when translation is inhibited, with resulting RNAP backtracking, replication blocks and formation of lethal DNA double-strand breaks. PMID- 29575156 TI - The overexpression of TcAP1 endonuclease confers resistance to infective Trypanosoma cruzi trypomastigotes against oxidative DNA damage. AB - Trypanosoma cruzi, the causative agent of Chagas' disease survives to DNA damage generated by ROS/RNS inside to their different hosts. In recent eukaryotes, oxidative DNA damage is repaired mainly by the Base Excision Repair (BER) pathway, being essential the apurinic/apyrimidinic endonuclease activity. Using a pTREX-gfp vector, the nucleotide sequence that encodes T. cruzi AP endonuclease TcAP1 (orthologue of human APE1) and a putative TcAP1 dominant negative (TcAP1DN), were transfectedand expressed in T. cruzi epimastigotes. TcAP1-GFP and TcAP1DN-GFP were expressed in those modified epimastigotes and found in the parasite nucleus. The endonucleases were purified under native conditions and the AP endonuclease activity was evaluated. While TcAP1 presents the expected AP endonuclease activity TcAP1DN does not. Moreover, TcAP1DN partially inhibits in vitro TcAP1 enzymatic activity. Transfected epimastigotes expressing TcAP1-GFP and TcAP1DN-GFP were differentiated to infective trypomastigotes. The infective parasites maintained both proteins (TcAP1-GFP and TcAP1DN-GFP) in the nucleus. The overexpression of TcAP1-GFP in epimastigotes and trypomastigotes increases the viability of both parasite forms when exposed to oxidative stress while the expression of TcAP1DN-GFP did not show any in vivo inhibitory effect, suggesting that endogenous TcAP1 constitutive expression overcomes the TcAP1DN inhibitory activity. Our results show that TcAP1 is important for trypomastigote survival under oxidative conditions similar to those found in infected mammalian cells, then increasing its permanence in the infected cells and the possibility of development of Chagas disease. PMID- 29575155 TI - Atypical audiovisual temporal function in autism and schizophrenia: similar phenotype, different cause. AB - Binding across sensory modalities yields substantial perceptual benefits, including enhanced speech intelligibility. The coincidence of sensory inputs across time is a fundamental cue for this integration process. Recent work has suggested that individuals with diagnoses of schizophrenia (SZ) and autism spectrum disorder (ASD) will characterize auditory and visual events as synchronous over larger temporal disparities than their neurotypical counterparts. Namely, these clinical populations possess an enlarged temporal binding window (TBW). Although patients with SZ and ASD share aspects of their symptomatology, phenotypic similarities may result from distinct etiologies. To examine similarities and variances in audiovisual temporal function in these two populations, individuals diagnosed with ASD (n = 46; controls n = 40) and SZ (n = 16, controls = 16) completed an audiovisual simultaneity judgment task. In addition to standard psychometric analyses, synchrony judgments were assessed using Bayesian causal inference modeling. This approach permits distinguishing between distinct causes of an enlarged TBW: an a priori bias to bind sensory information and poor fidelity in the sensory representation. Findings indicate that both ASD and SZ populations show deficits in multisensory temporal acuity. Importantly, results suggest that while the wider TBWs in ASD most prominently results from atypical priors, the wider TBWs in SZ results from a trend toward changes in prior and weaknesses in the sensory representations. Results are discussed in light of current ASD and SZ theories and highlight that different perceptual training paradigms focused on improving multisensory integration may be most effective in these two clinical populations and emphasize that similar phenotypes may emanate from distinct mechanistic causes. PMID- 29575157 TI - Finding meaning in suffering?-Meaning making and psychological adjustment over the course of a breast cancer disease. AB - This study aimed to explore individual meaning systems in the course of a breast cancer disease to test the assumed positive relation between meaning and well being and to investigate the relationship between post-traumatic growth and well being. A total of 65 patients with breast cancer were examined 1 year after initial treatment and another year follow-up. Questionnaires addressed meaning in life (MLQ), anxiety and depression (HADS), satisfaction with life (SWLS), health related quality of life (EQ-5D, EORTC) and post-traumatic growth (PTGI). Personal meaning systems were assessed using a qualitative method. In the personal meaning systems with well-being and relationships as the most frequently named meaning categories, the experienced gains far outweigh the losses sustained as a result of the disease. A stronger sense of meaning was related to lower levels of anxiety and depression, a higher level of satisfaction with life and better health-related functioning. Well-being and post-traumatic growth were mostly independent. Reported losses were strongly related to a poorer well-being. Cancer can induce a process of personal growth, and a strong sense of purpose could facilitate psychological adjustment. The often claimed correlation of post traumatic growth and a better psychological adjustment is still lacking clear evidence, whereas losses proofed to be crucial.

AB - RATIONALE: Protein citrullination (deimination) is a post-translational modification of proteins converting arginine(s) into citrulline(s). "Overcitrullination" could be associated with severe pathological conditions. Mass spectrometric analysis of modified proteins is hindered by several problems. A comprehensive study of the fragmentation of deiminated peptides is not yet available. In this paper we have made an attempt to describe the characteristics of these processes, based on the studies of epitope model oligopeptides derived from clinically relevant proteins. METHODS: Solutions of purified model peptides containing either one or two citrulline residues as well as their native variants were injected directly into the electrospray source of a high accuracy and resolution quadrupole-time-of-flight instrument and were analysed by tandem mass spectrometry using low-energy collision-induced dissociation. RESULTS: Loss of isocyanic acid from citrulline residues is a preferred fragmentation route for deiminated peptides, which yields ornithine residues in the sequence. However, simultaneous detection of both the isocyanic acid loss and sequence fragments is often compromised. A preferential cleavage site was observed between citrulline and any other following amino acids yielding intensive complementary b- and y type ions. Also, citrulline positioned at the C-termini displays a preferential cleavage N-terminal to this residue yielding characteristic y1 ions. These phenomena are described here for the first time and are referred to as the "citrulline effect". CONCLUSIONS: We found that the citrulline effect is very pronounced and could be used as a complementary tool for the confirmation of modification sites in addition to losses of isocyanic acids from the protonated molecules or from fragment ions. Low collision energy applied to peptide ions having partially mobile protons reveals the site of modification by generating specific and intensive fragments of the sequence. On the other hand, fragmenting precursor ions with mobile protons usually allows full sequence coverage, although citrulline-specific fragments may exhibit lower intensities compared to other fragments. PMID- 29575160 TI - Association of serious infections with pemphigus and pemphigoid: analysis of the Nationwide Inpatient Sample. AB - BACKGROUND: Pemphigus and pemphigoid are blistering disorders associated with barrier disruption, immune dysregulation and use of immunosuppressing systemic therapy, all of which may predispose towards serious infections. OBJECTIVES: To determine whether pemphigus and pemphigoid are associated with increased likelihood of serious infections and the impact of such infections on mortality and cost of care. METHODS: We analysed data from the 2002 to 2012 Nationwide Inpatient Sample, including a representative 20% sample of all hospitalizations in the US (total n = 72 108 077 adults). RESULTS: Overall, 54.6% (95% CI: 53.6 55.6%) and 50.4% (49.0-51.8%) of inpatients with either pemphigoid or pemphigus had a diagnosis of serious infection, respectively, compared with 25.4% (25.2 25.6%) in those without either diagnosis. In multivariable logistic regression models controlling for gender, age, race/ethnicity and insurance status, pemphigoid or pemphigus was associated with 26 or 21 of 48 infections examined, respectively. In particular, both pemphigoid and pemphigus were associated with higher odds of infections of the skin, bones, respiratory, gastrointestinal, genitourinary and central nervous system, septicaemia and antibiotic-resistant infections. Pemphigus was also associated with aspergillus, pharyngitis and Pneumocystis Carinii pneumonia. Associations of any serious infection in both pemphigoid and pemphigus patients were older age, non-White race, lower median household income, government or no insurance, higher number of chronic conditions, and those with a diagnosis of Cushing's syndrome, diabetes, cancer or autoimmune disease. The diagnosis of any serious infection vs. no infection was associated with increased inpatient mortality and costs in both pemphigoid (mortality: 7.85% vs. 2.84%; cost: $16 115 vs. $10 653) and pemphigus (mortality: 6.78% vs. 1.88%; cost: $17 707 vs. $11 545) inpatients (P < 0.0001 for all). CONCLUSIONS: Adults with pemphigus or pemphigoid had increased cutaneous, respiratory, multi-organ and systemic infections, which were associated with considerable inpatient mortality and cost burden. Moreover, there were significant clinical and healthcare disparities with respect to infections in patients with pemphigus or pemphigoid. PMID- 29575161 TI - Single-shot spiral imaging at 7 T. AB - PURPOSE: The purpose of this work is to explore the feasibility and performance of single-shot spiral MRI at 7 T, using an expanded signal model for reconstruction. METHODS: Gradient-echo brain imaging is performed on a 7 T system using high-resolution single-shot spiral readouts and half-shot spirals that perform dual-image acquisition after a single excitation. Image reconstruction is based on an expanded signal model including the encoding effects of coil sensitivity, static off-resonance, and magnetic field dynamics. The latter are recorded concurrently with image acquisition, using NMR field probes. The resulting image resolution is assessed by point spread function analysis. RESULTS: Single-shot spiral imaging is achieved at a nominal resolution of 0.8 mm, using spiral-out readouts of 53-ms duration. High depiction fidelity is achieved without conspicuous blurring or distortion. Effective resolutions are assessed as 0.8, 0.94, and 0.98 mm in CSF, gray matter and white matter, respectively. High image quality is also achieved with half-shot acquisition yielding image pairs at 1.5-mm resolution. CONCLUSION: Use of an expanded signal model enables single-shot spiral imaging at 7 T with unprecedented image quality. Single-shot and half-shot spiral readouts deploy the sensitivity benefit of high field for rapid high-resolution imaging, particularly for functional MRI and arterial spin labeling. PMID- 29575162 TI - On-line capillary electrophoresis/laser-induced fluorescence/mass spectrometry analysis of glycans labeled with TealTM fluorescent dye using an electrokinetic sheath liquid pump-based nanospray ion source. AB - RATIONALE: N-linked glycan analysis of recombinant therapeutic proteins, such as monoclonal antibodies, Fc-fusion proteins, and antibody-drug conjugates, provides valuable information regarding protein therapeutics glycosylation profile. Both qualitative identification and quantitative analysis of N-linked glycans on recombinant therapeutic proteins are critical analytical tasks in the biopharma industry during the development of a biotherapeutic. METHODS: Currently, such analyses are mainly carried out using capillary electrophoresis/laser-induced fluorescence (CE/LIF), liquid chromatography/fluorescence (LC/FLR), and liquid chromatography/fluorescence/mass spectrometry (LC/FLR/MS) technologies. N-linked glycans are first released from glycoproteins by enzymatic digestion, then labeled with fluorescence dyes for subsequent CE or LC separation, and LIF or MS detection. Here we present an on-line CE/LIF/MS N-glycan analysis workflow that incorporates the fluorescent TealTM dye and an electrokinetic pump-based nanospray sheath liquid capillary electrophoresis/mass spectrometry (CE/MS) ion source. RESULTS: Electrophoresis running buffer systems using ammonium acetate and ammonium hydroxide were developed for the negative ion mode CE/MS analysis of fluorescence-labeled N-linked glycans. Results show that on-line CE/LIF/MS analysis can be readily achieved using this versatile CE/MS ion source on common CE/MS instrument platforms. CONCLUSIONS: This on-line CE/LIF/MS method using TealTM fluorescent dye and electrokinetic pump-based nanospray sheath liquid CE/MS coupling technology holds promise for on-line quantitation and identification of N-linked glycans on recombinant therapeutic proteins. PMID- 29575163 TI - High-Voltage Lithium-Metal Batteries Enabled by Localized High-Concentration Electrolytes. AB - Rechargeable lithium-metal batteries (LMBs) are regarded as the "holy grail" of energy-storage systems, but the electrolytes that are highly stable with both a lithium-metal anode and high-voltage cathodes still remain a great challenge. Here a novel "localized high-concentration electrolyte" (HCE; 1.2 m lithium bis(fluorosulfonyl)imide in a mixture of dimethyl carbonate/bis(2,2,2 trifluoroethyl) ether (1:2 by mol)) is reported that enables dendrite-free cycling of lithium-metal anodes with high Coulombic efficiency (99.5%) and excellent capacity retention (>80% after 700 cycles) of Li||LiNi1/3 Mn1/3 Co1/3 O2 batteries. Unlike the HCEs reported before, the electrolyte reported in this work exhibits low concentration, low cost, low viscosity, improved conductivity, and good wettability that make LMBs closer to practical applications. The fundamental concept of "localized HCEs" developed in this work can also be applied to other battery systems, sensors, supercapacitors, and other electrochemical systems. PMID- 29575164 TI - Increasing specific immunoglobulin E levels correlate with the risk of anaphylaxis during an oral food challenge. AB - BACKGROUND: Oral food challenges (OFCs) are necessary to diagnose food allergies; however, these tests can cause anaphylaxis. Higher specific immunoglobulin E (sIgE) levels to causative food have been associated with a positive OFC. To date, no data have been found to indicate the factors associated with severe symptoms or anaphylaxis among challenge-positive patients. This study aimed to clarify the association of sIgE with causative foods and anaphylaxis during OFC among the whole study population and challenge-positive patients. METHODS: This cross-sectional study collected symptom and severity data between June 2012 and December 2016 during an open OFC to diagnose food allergy or confirm tolerance acquisition. We analyzed the risk factors for anaphylaxis during OFC. RESULTS: A total of 2272 cases were analyzed (median age: 3.5 years; egg: 1166 cases; milk: 589 cases; wheat: 388 cases; and peanut: 129 cases). Among 979 challenge-positive patients, anaphylactic reactions were observed in 334 cases. A statistically significant association was observed between anaphylaxis during OFC and higher sIgE levels to causative foods (odds ratio: 2.71, 95% confidence interval: 1.94 3.78, for the third compared to the first tertile, P-value for trend <.001). Only gastrointestinal, respiratory, cardiovascular, and neurological symptoms were also statistically significantly associated with higher sIgE levels to causative foods. CONCLUSIONS: The risk of all symptoms, except skin symptoms, during OFCs increased with increasing sIgE levels, and this consequently increased anaphylaxis during OFCs. The mechanism of how sIgE affects the prevalence of gastrointestinal, respiratory, cardiovascular, and neurological symptoms or anaphylaxis is unknown; thus, further study is required. PMID- 29575165 TI - Integrating the fundamentals of care framework in baccalaureate nursing education: An example from a nursing school in Denmark. AB - AIMS AND OBJECTIVES: To describe and discuss the process of integrating the Fundamentals of Care framework in a baccalaureate nursing education at a School of Nursing in Denmark. BACKGROUND: Nursing education plays an essential role in educating nurses to work within healthcare systems in which a demanding workload on nurses results in fundamental nursing care being left undone. Newly graduated nurses often lack knowledge and skills to meet the challenges of delivering fundamental care in clinical practice. To develop nursing students' understanding of fundamental nursing, the conceptual Fundamentals of Care framework has been integrated in nursing education at a School of Nursing in Denmark. DESIGN AND METHODS: Discursive paper using an adjusted descriptive case study design for describing and discussing the process of integrating the conceptual Fundamentals of Care Framework in nursing education. RESULTS: The process of integrating the Fundamentals of Care framework is illuminated through a description of the context, in which the process occurs including the faculty members, lectures, case-based work and simulation laboratory in nursing education. Based on this description, opportunities such as supporting a holistic approach to an evidence based integrative patient care and challenges such as scepticism among the faculty are discussed. CONCLUSION: It is suggested how integration of Fundamentals of Care Framework in lectures, case-based work and simulation laboratory can make fundamental nursing care more explicit in nursing education, support critical thinking and underline the relevance of evidence-based practice. The process relies on a supportive context, a well-informed and engaged faculty, and continuous reflections on how the conceptual framework can be integrated. RELEVANCE TO CLINICAL PRACTICE: Integrating the Fundamentals of Care framework can support nursing students' critical thinking and reflection on what fundamental nursing care is and requires and eventually educate nurses in providing evidence-based fundamental nursing care. PMID- 29575166 TI - Anatomy of medial plantar superficial branch artery perforators: Facilitation of medial plantar superficial branch artery perforator (MPAP) flap harvesting and design for finger pulp reconstruction. AB - BACKGROUND: Medial plantar artery perforator (MPAP) flap was proposed as proper option for finger pulp reconstruction. To provide the previously unavailable vessel information required for this small flap design, this study aimed to gather all necessary anatomy of MPA, MPAP, and their territories of blood supply to apply in clinical MPAP flap reconstruction minimizing perforator injury. METHODS: Dissection of 30 Thai cadaveric feet for visualizing superficial branch of MPA and its perforators (MPAP) using acrylic dye cannulation were performed. Diameter, length, number of branches, course, distributing areas of these vessels, and also their areas of blood supply were recorded in relation to specified landmarks, eg, C-MTH line; medial calcaneal tuberosity to plantar side of the first metatarsal head and S point; emerging point of superficial branch of MPA from deep fasciae into subcutaneous layer. RESULTS: Average diameter of MPA at its origin and total length are 1.63 +/- 0.3 and 52.8 +/- 16.1 mm, respectively. It provides 1-3 perforators, with an average size and length of 0.36 +/- 0.11 and 23.2 +/- 5.47 mm, respectively. Its distribution is mostly in the posteromedial quadrant within 50 and 30 mm from the midpoint of C-MTH line and the S point, respectively. The estimated perforator flap area is 2.5 cm * 1.5 cm and 4.5 cm * 2.5 cm for single and double perforators, respectively. CONCLUSIONS: MPAP flap was proved as another ideal option for finger pulp reconstruction. Its limitation is small size of perforators but this can be overcome by using MPA for microsurgical anastomosis instead. PMID- 29575167 TI - Empirical treatment of outpatients with gastroesophageal reflux disease with proton pump inhibitors: A survey of Chinese patients (the ENLIGHT Study). AB - BACKGROUND AND AIM: Empirical proton pump inhibitor (PPI) treatment is recommended as a diagnostic indicator for gastroesophageal reflux disease (GERD) and as a therapy for symptomatic control, with responses generally seen within 4 weeks. However, there are no real-world data assessing the effectiveness of short term empirical treatment with PPIs in patients with GERD in China. METHODS: The ENLIGHT study was a multicenter, prospective, observational study conducted in China. The primary outcome was the overall response rate after 4 weeks' empirical treatment with PPIs. Adult patients aged between 18 and 65 years of age, with a gastroesophageal reflux disease questionnaire score of >= 8, prescribed empirical PPI treatment by their physicians and with no planned endoscopy were eligible to participate. Statistical analyses were primarily descriptive. RESULTS: Overall, 987 patients were eligible to participate and were included in the full analysis set (FAS); 707 patients were included in the per protocol set. In the FAS, esomeprazole was received by 57.1% of patients and was the most commonly used PPI. After 4-week treatment, 71.1% (95% confidence interval [CI], 67.9% to 74.2%) of patients were considered responders to PPI. The response rate at the end of 2 week PPI treatment reached 57.0% (95% CI, 52.5% to 61.7%). The median time to response was 13 days (95% CI, 12 to 15). Response rates at 2 and 4 weeks of the per protocol set were similar to those of the FAS. CONCLUSIONS: Short-term empirical PPI treatment can provide an effective relief of GERD symptoms in most Chinese patients in real-world practice. PMID- 29575168 TI - Site-level risk predictors of peri-implantitis: A retrospective analysis. AB - AIM: The goal of the present investigation was to identify site-level factors that might allow prognostication of individual implants in partially dentate patients with multiple non-splinted restorations. METHODS: We analysed clinical and radiographic characteristics of 222 non-splinted single implants in function for at least 5 years in 86 partially dentate individuals at the time of functional loading and at follow-up, with the outcome variable being peri implantitis. Principal component analysis identified factors contributing to greatest variability and linear discriminant analysis coupled with Random Forest Classifier used to identify risk predictors. RESULTS: After controlling for patient-level factors, the following characteristics were associated with significantly increased risk for peri-implantitis: Periodontal disease on adjoining teeth at the time of restoration (Odds Ratio (OR): 8.0), implant placement at a depth of 6 mm or more in relation to the CEJ of adjacent tooth (OR: 8.5), asymmetric prosthesis (OR: 4.3), history of tooth loss due to periodontitis (OR: 2.4) and a mean baseline plaque index of 1.6 or more (OR: 7.9). CONCLUSIONS: Our findings suggest that a system that incorporates both subject level and implant-level factors is required to effectively prognosticate the success of individual implants. PMID- 29575169 TI - Laser capture microdissection for detecting the expression of epithelial mesenchymal transition-related genes in epithelial and spindle cells of paraffin embedded formalin-fixed biphasic synovial sarcoma. AB - Synovial sarcoma (SS) is a mesenchymal malignant neoplasm showing characteristics of epithelial-mesenchymal biphasic differentiation. SS is of uncertain cellular origin; however, studies have suggested that SS originates from a somatic stem cell population. In this study, we aim to determine whether differential morphological features of the epithelial-mesenchymal transition (EMT) contributed to the tumourigenesis of SS invasion and metastasis. Twelve paraffin-embedded formalin-fixed tissue (FFPE) SS tissue specimens were obtained, and laser capture microdissection (LCM) with the ArcturusXT system and small chip method (SCM) were used to isolate and purify spindle and epithelial cells from SS specimens. The TRIzol method was used to extract RNA, and the mRNA levels of EMT-related genes in epithelial and spindle cells of SS specimens were measured using real-time fluorescent quantitative reverse transcription polymerase chain reaction (qRT PCR). The results show that collection of about 2 * 104 cells from FFPE samples using LCM was sufficient for qRT-PCR, with an efficiency of 75%. Compared with LCM, 72.2% (13 of 18) RNA samples were successfully extracted using SCM to isolate cells from FFPE SS tissues. In the 16 samples (11 spindle cell samples and 5 epithelial cell samples), Snail mRNA was significantly upregulated in spindle cell areas compared with that in epithelial cell areas (P = .001). Expression levels of the epithelial marker E-cadherin and the mesenchymal marker N-cadherin were not significantly different between epithelial and spindle cell areas. In spindle cells of recurrent SS samples, the mRNA levels of E-cadherin, N cadherin, Snail, and Slug were higher in primary SS samples than in recurrent samples. Taken together, our results indicated that in SS samples, Snail mRNA was upregulated in spindle cell areas compared with that in epithelial cell areas and that the expression of EMT-related genes was increased in primary SS. LCM could be used to isolate and purify RNA from FFPE samples. PMID- 29575170 TI - Random-effects meta-analysis of the clinical utility of tests and prediction models. AB - The use of data from multiple studies or centers for the validation of a clinical test or a multivariable prediction model allows researchers to investigate the test's/model's performance in multiple settings and populations. Recently, meta analytic techniques have been proposed to summarize discrimination and calibration across study populations. Here, we rather consider performance in terms of net benefit, which is a measure of clinical utility that weighs the benefits of true positive classifications against the harms of false positives. We posit that it is important to examine clinical utility across multiple settings of interest. This requires a suitable meta-analysis method, and we propose a Bayesian trivariate random-effects meta-analysis of sensitivity, specificity, and prevalence. Across a range of chosen harm-to-benefit ratios, this provides a summary measure of net benefit, a prediction interval, and an estimate of the probability that the test/model is clinically useful in a new setting. In addition, the prediction interval and probability of usefulness can be calculated conditional on the known prevalence in a new setting. The proposed methods are illustrated by 2 case studies: one on the meta-analysis of published studies on ear thermometry to diagnose fever in children and one on the validation of a multivariable clinical risk prediction model for the diagnosis of ovarian cancer in a multicenter dataset. Crucially, in both case studies the clinical utility of the test/model was heterogeneous across settings, limiting its usefulness in practice. This emphasizes that heterogeneity in clinical utility should be assessed before a test/model is routinely implemented.

AB - Sheep hips have a natural non-spherical head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoroacetabular impingement can be induced experimentally. In sheep, the aspherical portion is located superiorly-exactly matching the region where the superior retinacular vessels enter the femoral head-neck junction in human beings. In order to fully exploit the potential of this experimental FAI model, a safe osteochondroplasty of the superior asphericity would need to be done without the risk of avascular necrosis. The aim of this study was to describe the vascular anatomy of the femoral head in sheep from the aorta to the retinacular vessels in order to perform safe femoral osteochondroplasty of the superior femoral asphericity in sheep. Sixty-two ovine hips were analyzed using CT angiography (30 hips), post mortem intravascular latex injection (6 hips), vascular corrosion casting (6 hips), and analysis of the distribution of vascular foramina around the femoral head-neck junction in macerated ovine femora (20 hips). The ovine femoral head receives its blood supply from anterior retinacular arteries from the lateral femoral circumflex artery, and from posterior retinacular arteries from the medial femoral circumflex artery. The superior aspherical portion is free of vessels. Detailed knowledge about vascular anatomy of sheep hips is of clinical significance since it allows to perform osteochondroplasty of the superior aspherical portion in the experimental ovine FAI model safely without the risk of osteonecrosis.

AB - M[BeSi2 N4 ] (M=Sr,Eu), crystallizing in the hexagonal space group P6? 2c, was synthesized from Sr(NH2 )2 , Be3 N2 , and "Si(NH)2 " in W crucibles under a N2 atmosphere in a radio-frequency furnace. The crystal structure was solved from powder X-ray diffraction data by the charge-flipping method (Sr[BeSi2 N4 ]: a=4.86082(2), c=9.42264(4) A, Z=2; Eu[BeSi2 N4 ]: a=4.85848(1), c=9.41615(4) A). M[BeSi2 N4 ] contains a highly condensed rigid network of trigonal planar [BeN3 ] units that are connected to Si2 N7 double tetrahedra by common vertices. M[BeSi2 N4 ] (M=Sr,Eu) are the first examples of nitridoberyllosilicates and are isotypic to the oxoberyllate Sr[Be3 O4 ]. Eu2+ -doped Sr[BeSi2 N4 ] and Eu[BeSi2 N4 ] show orange-trapped exciton emission (lambdaem =605 nm, fwhm ~126 nm), whereas Ce3+ doped samples of Sr[BeSi2 N4 ] show nontypical yellowish-orange luminescence. Sr[BeSi2 N4 ] has a large band gap of ~4.4 eV and shows high chemical and thermal stability. Eu2+ -doped beryllates with regular 4f6 5d1 ->4f7 -emission could be interesting for future application in LEDs upon doping with Eu2+ or Ce3+ due to large band gaps, rigid networks, and chemical and thermal stability.

In the present study, the anticancer effects of cucurbitacin I on A549 cells were investigated. Cucurbitacin I decreased cell viability, inhibited colony formation, and induced apoptosis in A549 cells. Cucurbitacin I caused accumulation of autophagosome and dose-dependent expression of LC3II protein. Autophagy inhibitors 3-methyladenine (3-MA) inhibited autophagy induced by cucurbitacin I and relieved cucurbitacin I-triggered cell death and apoptosis in A549 Cells. Cucurbitacin I treatment inhibits the ERK activation and the downstream phosphorylation level of mTOR and STAT3, but not the PI3K/Akt pathway. Furthermore, treatment with the mTOR activator MHY-1485, which also suppressed cucurbitacin I-induced LC3II expression, and also reversed cucurbitacin I-induced cell death and apoptosis. Taken together, these results suggest that cucurbitacin I induced pro-death autophagy through ERK/mTOR/STAT3 signaling cascade in A549 cells. PMID- 29575176 TI - Rapid synthesis of maleimide functionalized fluorine-18 labeled prosthetic group using "radio-fluorination on the Sep-Pak" method. AB - Following our recently published fluorine-18 labeling method, "Radio-fluorination on the Sep-Pak", we have successfully synthesized 6-[18 F]fluoronicotinaldehyde by passing a solution (1:4 acetonitrile: t-butanol) of its quaternary ammonium salt precursor, 6-(N,N,N-trimethylamino)nicotinaldehyde trifluoromethanesulfonate (2), through a fluorine-18 containing anion exchange cartridge (PS-HCO3 ). Over 80% radiochemical conversion was observed using 10 mg of precursor within 1 minute. The [18 F]fluoronicotinaldehyde ([18 F]5) was then conjugated with 1-(6 (aminooxy)hexyl)-1H-pyrrole-2,5-dione to prepare the fluorine-18 labeled maleimide functionalized prosthetic group, 6-[18 F]fluoronicotinaldehyde O-(6 (2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)hexyl) oxime, 6-[18 F]FPyMHO ([18 F]6). The current Sep-Pak method not only improves the overall radiochemical yield (50 +/- 9%, decay-corrected, n = 9) but also significantly reduces the synthesis time (from 60-90 minutes to 30 minutes) when compared with literature methods for the synthesis of similar prosthetic groups. PMID- 29575177 TI - A longitudinal study of fractures in 1488 Thoroughbred racehorses receiving intrasynovial medication: 2006-2011. AB - BACKGROUND: There is a need for investigation of associations between intrasynovial medication and fracture risk in racehorses. OBJECTIVES: To document the proportion and type of fracture occurring following intrasynovial medication. STUDY DESIGN: Retrospective longitudinal study. METHODS: Review of clinical records from all Thoroughbred flat racehorses receiving intrasynovial medication under the care of a first-opinion veterinary practice between 2006 and 2011. Fractures pre- and post-medication were categorised by location, type, and severity; analysis of fractures sustained within 56-days of medication was undertaken. Survival analyses using Cox proportional hazards models were conducted for associations between medication used (corticosteroid vs. non corticosteroid), age at first medication, sex and total number of medications and fracture. RESULTS: A total of 1488 horses received intrasynovial medication during the period of study; 8692 synovial spaces were medicated in 3925 sessions. There were 96 fractures that occurred within 56-days of medication, of which 44 were classified as 'serious' (44/1488; 3.0% total population, 95% CI 2.1, 3.8%) and 11 (11/1488, 0.7%, 95% CI 0.3, 1.2%) were euthanased due to severity of injury. Fifty-four of 96 cases (56.4%, 95% CI 46.3, 66.2%) returned to racing. Targeted imaging of the subsequent injury site was undertaken prior to injury in only 7 (7/96, 7.3%) horses that injured post-medication. Horses that had received >=3 previous intrasynovial medication sessions had an increased hazard of sustaining a fracture within 56 days (HR 2.31, 95% CI 1.51, 3.54, P<0.001) compared with those receiving <=3 medication sessions, adjusted for each increasing year of age (HR 0.67, 95% CI 0.53, 0.86, P = 0.001). MAIN LIMITATIONS: Absence of an unexposed cohort of nonmedicated racehorses. CONCLUSIONS: Serious musculoskeletal injury following intrasynovial medication occurred in 3% (44/1488) horses. Reduction in injury rates may be possible through greater use of premedication diagnostic imaging. PMID- 29575179 TI - Sensitization to minor cat allergen components is associated with type-2 biomarkers in young asthmatics. AB - BACKGROUND: Cat allergy is a major trigger of asthma world-wide. Molecular patterns of cat sensitization vary between individuals, but their relationship to inflammation in asthmatics has not been extensively studied. OBJECTIVE: To investigate the prevalence and levels of IgE antibodies against different cat allergen components and their relationship to type-2 inflammation and total IgE among young asthmatic subjects sensitized to furry animals. METHODS: Patients with asthma (age 10-35 years; n = 266) and IgE sensitization to cat, dog or horse extract (ImmunoCAP), were analysed for IgE to the cat allergen components Fel d 1 (secretoglobin), Fel d 2 (serum albumin), Fel d 4 and Fel d 7 (lipocalins). Independent associations between IgE-antibody concentrations, and fraction of exhaled nitric oxide (FeNO), blood eosinophil (B-Eos) count, and total IgE were analysed by multiple linear regression after adjustment for possible confounders. RESULTS: The level of IgE against Fel d 2 was independently related to FeNO (P = .012) and total IgE (P < .001), and IgE against Fel d 4 associated with Beta-Eos count (P = .009) and total IgE (P < .001). IgE antibodies against Fel d 1 or cat extract did not independently relate to these inflammatory markers (P = .23-.51). CONCLUSIONS: Levels of IgE to lipocalin (Fel d 4) and serum albumin (Fel d 2), but not to secretoglobin (Fel d 1) or cat extract, were independently associated with type-2 biomarkers and total IgE in young asthmatics. CLINICAL RELEVANCE: We suggest that measurement of IgE to minor cat allergen components may be useful when investigating asthma morbidity in cat allergic subjects. PMID- 29575180 TI - Sonographic assessment of the anal sphincter after obstetric anal sphincter injury (OASI) using transperineal ultrasound (TPUS). AB - Obstetric anal sphincter injury (OASI) is the most common cause of anal incontinence and ano-rectal symptoms in women1 . Reported rates of anal incontinence following primary repair of OASI range between 15-61%, with a mean of 39%2, 3 . Other possible complications of OASI include perineal pain, dyspareunia, and less commonly, abscess formation, wound breakdown, and rectovaginal fistulae. Symptom onset may occur immediately, several years postpartum, or only late in life when aging of tissues adds to the delivery insult. Having sustained an OASI may impact significantly on women's physical and emotional health. Missed OASI, inadequate repair or lack of follow up are potential sources of litigation4 . The reported incidence of OASI may be as high as 4-6.6%4 , averaging 2.9% in the UK3 . The incidence is higher in primiparae (6.1%) than in multiparae (1.7%) 3 . Recent years are seeing an increased awareness and structured training programs, which appear to have resulted in an increase in the detection rate of OASI3 . The following risk factors have been identified with varying risk rates reported3 : Asian ethnicity (OR 2.27, 95% CI 2.14-2.41), nulliparity (relative risk [RR] 6.97, 95% CI 5.40-8.99), birth weight greater than 4 kg (OR 2.27, 95% CI 2.18-2.36), shoulder dystocia (OR 1.90, 95% CI 1.72-2.08), occipito-posterior position (RR 2.44, 95% CI 2.07-2.89), prolonged second stage of labor (up to RR 2.02, 95% CI 1.62-2.51 after four hours duration). Instrumental deliveries and episiotomy use have been extensively studied resulting in the following evidence: Vacuum delivery without episiotomy (OR 1.89, 95% CI 1.74-2.05); vacuum delivery with episiotomy is protective (OR 0.57, 95% CI 0.51-0.63); forceps delivery without episiotomy carries the highest potential risk (OR 6.53, 95% CI 5.57-7.64); and forceps delivery with episiotomy (OR 1.34, 95% CI 1.21-1.49). Other potential risk factors have been suggested with varying evidence such as advanced maternal age at first birth, Asian race, a vaginal birth after cesarean, and type of obstetrical care provider4 . Possible protective factors include obesity, perineal massage (RR 0.91, 95% CI 0.86-0.96)5 , perineal protection at crowning3 , warm compression during the second stage of labor (RR 0.48, 95% CI 0.28-0.84)3 , mediolateral episiotomy in instrumental deliveries6 , a wide angle of the mediolateral episiotomy (at least 60 degrees away from the midline when the perineum is distended) 7 , and pre-labor cesarean section4 . However, clinicians and patients alike should be aware that risk factors do not allow the accurate prediction of OASI3 . OASI is usually diagnosed in the immediate postpartum period. The classification is based on the extent of lacerations to the external and internal anal sphincter (EAS and IAS, respectively) and epithelium as devised by Sultan 2,3,8 (Figure 1) and adopted by the World Health Organization (WHO). The degree of damage impacts on the development of symptoms, with 3C and 4th degree tears carrying a graver prognosis than 3A and 3B tears9 . It is not unusual for a tear to be missed in the labor ward: the reported rates of missed OASI range from 26-87%10 . Since all women having a vaginal delivery are at risk of sustaining OASI, they should be examined systematically, including a digital rectal examination, to assess the severity of damage, prior to suturing3 . PMID- 29575178 TI - Technique development of 3D dynamic CS-EPSI for hyperpolarized 13 C pyruvate MR molecular imaging of human prostate cancer. AB - PURPOSE: The purpose of this study was to develop a new 3D dynamic carbon-13 compressed sensing echoplanar spectroscopic imaging (EPSI) MR sequence and test it in phantoms, animal models, and then in prostate cancer patients to image the metabolic conversion of hyperpolarized [1-13 C]pyruvate to [1-13 C]lactate with whole gland coverage at high spatial and temporal resolution. METHODS: A 3D dynamic compressed sensing (CS)-EPSI sequence with spectral-spatial excitation was designed to meet the required spatial coverage, time and spatial resolution, and RF limitations of the 3T MR scanner for its clinical translation for prostate cancer patient imaging. After phantom testing, animal studies were performed in rats and transgenic mice with prostate cancers. For patient studies, a GE SPINlab polarizer (GE Healthcare, Waukesha, WI) was used to produce hyperpolarized sterile GMP [1-13 C]pyruvate. 3D dynamic 13 C CS-EPSI data were acquired starting 5 s after injection throughout the gland with a spatial resolution of 0.5 cm3 , 18 time frames, 2-s temporal resolution, and 36 s total acquisition time. RESULTS: Through preclinical testing, the 3D CS-EPSI sequence developed in this project was shown to provide the desired spectral, temporal, and spatial 5D HP 13 C MR data. In human studies, the 3D dynamic HP CS-EPSI approach provided first ever simultaneously volumetric and dynamic images of the LDH-catalyzed conversion of [1-13 C]pyruvate to [1-13 C]lactate in a biopsy-proven prostate cancer patient with full gland coverage. CONCLUSION: The results demonstrate the feasibility to characterize prostate cancer metabolism in animals, and now patients using this new 3D dynamic HP MR technique to measure kPL , the kinetic rate constant of [1 13 C]pyruvate to [1-13 C]lactate conversion. PMID- 29575181 TI - Familial papular epidermal nevus with "skyline" basal cell layer. AB - Papular epidermal nevus with "skyline" basal cell layer is a variant of keratinocytic nevus that usually occurs sporadically but may affect different family members. We report on the fourth family with papular epidermal nevus with "skyline" basal cell layer affecting a 3-month-old girl and her father. PMID- 29575182 TI - Comparison of pre- and post-transplant sun-safe behavior of kidney transplant recipients: What is needed to improve? AB - BACKGROUND: The role of sun exposure in the development of melanoma and nonmelanoma skin cancers is known; however, there are limited data on the contribution of pretransplantation total sun burden (TSB) to the increased skin cancer risk in organ transplant recipients (OTRs). The importance of patient education about sun-safe behaviors is understood, but educations are often unsuccessful in OTRs. METHODS: A questionnaire-based cross-sectional study was performed with kidney transplant patients at a single academic center to assess the pre- and post-transplant sun exposure, sun protection habits, and skin cancers. RESULTS: Two hundred and twenty-one patients participated in the study. 13.1% developed at least one skin cancer. High total sun burden before transplantation was reported by 58.4%, and 65.2% reported education about increased skin cancer risk at the time of transplantation. However, that education did not lead to less sun exposure or better sun protection methods after transplantation. Overall, OTR related but not sun protection-guided lifestyle changes affecting OTRs after transplantation led to reduction in sun exposure. CONCLUSION: Our findings highlight the need for more tailored, population-specific education programmes, even for patients who expect to receive a transplant in the future, and suggest the importance of pretransplantation TSB in determining the post-transplant skin cancer risk. PMID- 29575183 TI - Giant cell tumour of tendon sheath: A 10-year study from a tertiary care centre. AB - INTRODUCTION: Cytology of giant cell tumour of tendon sheath (GCTTS) is often sufficient to diagnose this lesion and has been previously described in small series. The present study was undertaken to evaluate detailed cytomorphological features and differential diagnostic entities and pitfalls in the diagnosis. METHODS: All the cases of GCTTS reported on FNAC were retrieved from July 2007 to June 2017. The cases were reviewed for various cytomorphological features, which were correlated with follow-up histopathology wherever available. RESULTS: A total of 72 cases of GCTTS were retrieved, follow-up histopathology was available in 20 cases. The common sites of involvement were fingers and palm followed by wrists, elbow, knee, ankle and shoulder. The characteristic cytomorphology consisted of mononuclear cells, multinucleated giant cells and pigment laden macrophages in variable numbers. There were four discordant cases that were confirmed on histopathology as sarcoidosis, melanoma, fibrous histiocytoma and eumycetoma. CONCLUSIONS: GCTTS can be confused cytologically with giant cell rich lesions of bone and soft tissue and pigment containing lesions including melanoma. Ladybird cell is a characteristic feature seen in this lesion. Proper clinicoradiological correlation is essential before offering a diagnosis of GCTTS on cytology. PMID- 29575184 TI - A Multifaceted Study of Methane Adsorption in Metal-Organic Frameworks by Using Three Complementary Techniques. AB - Methane is a promising clean and inexpensive energy alternative to traditional fossil fuels, however, its low volumetric energy density at ambient conditions has made devising viable, efficient methane storage systems very challenging. Metal-organic frameworks (MOFs) are promising candidates for methane storage. In order to improve the methane storage capacity of MOFs, a better understanding of the methane adsorption, mobility, and host-guest interactions within MOFs must be realized. In this study, methane adsorption within alpha-Mg3 (HCO2 )6 , alpha-Zn3 (HCO2 )6 , SIFSIX-3-Zn, and M-MOF-74 (M=Mg, Zn, Ni, Co) has been comprehensively examined. Single-crystal X-ray diffraction (SCXRD) experiments and DFT calculations of the methane adsorption locations were performed for alpha-Mg3 (HCO2 )6 , alpha-Zn3 (HCO2 )6 , and SIFSIX-3-Zn. The SCXRD thermal ellipsoids indicate that methane possesses significant mobility at the adsorption sites in each system. 2 H solid-state NMR (SSNMR) experiments targeting deuterated CH3 D guests in alpha-Mg3 (HCO2 )6 , alpha-Zn3 (HCO2 )6 , SIFSIX-3-Zn, and MOF-74 yield an interesting finding: the 2 H SSNMR spectra of methane adsorbed in these MOFs are significantly influenced by the chemical shielding anisotropy in addition to the quadrupolar interaction. The chemical shielding anisotropy contribution is likely due mainly to the nuclear independent chemical shift effect on the MOF surfaces. In addition, the 2 H SSNMR results and DFT calculations strongly indicate that the methane adsorption strength is linked to the MOF pore size and that dispersive forces are responsible for the methane adsorption in these systems. This work lays a very promising foundation for future studies of methane adsorption locations and dynamics within adsorbent MOF materials. PMID- 29575185 TI - Identification of VIM-2 metallo-beta-lactamase-producing Pseudomonas aeruginosa isolated from dogs with pyoderma and otitis in Korea. AB - BACKGROUND: Pseudomonas aeruginosa is a challenging pathogen cultured from cases of acute and chronic canine otitis and sometimes in cases of deep pyoderma. The spread of antimicrobial resistance, especially carbapenem resistance, is a serious therapeutic challenge worldwide. HYPOTHESIS/OBJECTIVES: To investigate the identification and characterization of resistant P. aeruginosa clinical canine isolates. MATERIALS: Clinical isolates (n = 80) were collected from dogs with pyoderma (n = 18) and otitis (n = 62) in Korea. METHODS: Antimicrobial susceptibility was determined using agar dilution and using Clinical and Laboratory Standards Institute guidelines for recording susceptibility for human Pseudomonas isolates; genetic relatedness of isolates was investigated by multilocus sequence typing (MLST) and SpeI macrorestriction analysis. The class 1 integrons were amplified and sequenced using primer walking. RESULTS: Most isolates were susceptible to colistin (97.5%), polymyxin B (96.3%), ciprofloxacin (81.3%) and meropenem (80.0%); whereas resistance to aztreonam (80%), piperacillin (52.5%), piperacillin/tazobactam (41.3%) and cefepime (37.5%) was high; 12 carbapenem-nonsusceptible isolates (15%) were detected. MLST revealed 45 different sequence types (STs) and macrorestriction analysis detected 55 distinct pulsotypes (PTs), which were divided into 25 clonal groups. Among carbapenem nonsusceptible isolates, 10 (83.3%) were VIM-2-producing strains. Nine VIM-2 producing isolates were identified as ST1047 and harboured the same 2.8 kb class 1 integron. One remaining isolate was ST1203 with 2.1 kb class 1 integron. CONCLUSIONS AND CLINICAL IMPORTANCE: This study demonstrated the diversity of the phenotype and genotype of clinical P. aeruginosa isolates from dogs with pyoderma and otitis. The identification of VIM-2-producing P. aeruginosa in dogs is alarming and warrants further surveillance. PMID- 29575187 TI - Culex pipiens sperm motility is initiated by a trypsin-like protease from male accessory glands. AB - In most animals, sperm are stored in a quiescent state in the male reproductive tract and only initiate motility when released into either the female reproductive tract, or, in the case of broadcast spawners, the external environment. Male accessory gland secretions transferred into the female reproductive tract may provide factors that modulate sperm viability and storage, or aid in sperm competition, as well as activate sperm motility. In several insects, serine proteases have been implicated in activating sperm motility. Our previous studies have shown that, in Culex quinquefasciatus, either a male accessory gland extract or purified trypsin is sufficient to initiate sperm motility in vitro. The objective of this study was to identify and characterize trypsin-like enzymes produced in the Culex male accessory glands. Mass spectrometry was used to analyze accessory gland proteins and this preliminary proteomic analysis identified 4 trypsin-like proteases (trypsin, trypsin4, and two trypsin7 isoforms). When measured with the chromogenic trypsin substrate Na benzoyl-L-arginine-ethyl-ester-hydrochloride (BAEE), trypsin-like protease activity in the accessory glands was robust, with a pH optimum of 8. The pH range for the Culex trypsin activity was substantially narrower than a mammalian homologue (porcine pancreatic trypsin). A soybean trypsin inhibitor (SBTI) agarose affinity column was used to independently identify trypsin-like accessory gland proteins. Several proteins were enriched in the eluate, as detected by silver staining of SDS-PAGE gels. Taken together, these data demonstrate the presence of trypsin-like activity and several trypsin-like proteins in the Culex male accessory glands. PMID- 29575186 TI - Nitrogen-Functionalized Hydrothermal Carbon Materials by Using Urotropine as the Nitrogen Precursor. AB - Nitrogen-containing hydrothermal carbon (N-HTC) materials of spherical particle morphology were prepared by means of hydrothermal synthesis with glucose and urotropine as precursors. The molar ratio of glucose to urotropine has been varied to achieve a continuous increase in nitrogen content. By raising the ratio of urotropine to glucose, a maximal nitrogen fraction of about 19 wt % could be obtained. Decomposition products of both glucose and urotropine react with each other; this opens up a variety of possible reaction pathways. The pH has a pronounced effect on the reaction pathway of the corresponding reaction steps. For the first time, a comprehensive analytical investigation, comprising a multitude of analytical tools and instruments, of a series of nitrogen-containing HTC materials was applied. Functional groups and structural motifs identified were analyzed by means of FTIR spectroscopy, thermogravimetric MS, and solid state NMR spectroscopy. Information on reaction mechanisms and structural details were obtained by electronic structure calculations that were compared with vibrational spectra of polyfuran or polypyrrole-like groups, which represent structural motifs occurring in the present samples. PMID- 29575188 TI - Hand fasciae innervation: The palmar aponeurosis. AB - There are few data in the scientific literature about the innervation of fasciae of the hand. The present study first elucidates the density and location of nervous structures in the palmar aponeurosis and, for comparison, in the flexor retinaculum (both can be considered specializations of the deep fascia of the upper limbs). Second, it compares nonpathological with pathological palmar aponeurosis. Samples of nonpathological fascia were taken from the flexor retinaculum and palmar aponeurosis of 16 upper limbs of unembalmed cadavers. Samples of pathological palmar aponeurosis were taken from seven patients with Dupuytren's disease. All samples were stained immunohistochemically with anti S100 and anti-tubulin antibodies, and analyzed quantitatively and qualitatively by microscopy. The palmar aponeurosis showed higher median density than the retinacula of free nerve endings (22 and 20 elements/cm2 , respectively), Pacinian corpuscles (2 and 0 elements/cm2 ) and Golgi-Mazzoni corpuscles (1.0 and 0.5 element/cm2 ). Some corpuscles were located at the intersections of the fibers in the three directions. Free nerve endings were denser in pathological palmar aponeurosis (38 elements/cm2 ). The results indicate that the palmar aponeurosis is central to proprioception of the hand and that surgery should therefore avoid injuring it. The higher density of free nerve endings in pathological samples indicates that the nervous structures are implicated in the amplified fibrosis of Dupuytren's disease. Clin. Anat. 31:677-683, 2018.

AB - AIM: This study aimed to evaluate and compare the performance of two methodological instruments to appraise systematic reviews and to identify potential disagreements of systematic review authors regarding risk of bias (RoB) evaluation of randomized controlled trials (RCTs) included in systematic reviews on peri-implant diseases. MATERIAL/METHODS: We searched Medline, Web of Science, Cochrane Library, PubMed Central, and Google Scholar for systematic reviews on peri-implant diseases published before July 11, 2017. Two authors independently evaluated the RoB and methodological quality of the systematic reviews by applying the Risk of Bias in Systematic Reviews (ROBIS) tool and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) checklist, respectively. We assessed the RoB scores of the same RCTs published in different systematic reviews. RESULTS: Of the 32 systematic reviews identified, 23 reviews addressed the clinical topic of peri-implantitis. A high RoB was detected for most systematic reviews (n=25) using ROBIS, whilst five systematic reviews displayed low methodological quality by AMSTAR. Almost 30% of the RoB comparisons (for the same RCTs) had different RoB ratings across systematic reviews. CONCLUSIONS: The ROBIS tool appears to provide more conservative results than AMSTAR checklist. Considerable disagreement was found among systematic review authors rating the same RCT included in different systematic reviews. PMID- 29575190 TI - Photocatalysis with Quantum Dots and Visible Light for Effective Organic Synthesis. AB - Colloidal semiconductor quantum dots (QDs) have recently attracted widespread interest for diverse applications. Owing to their quantum confinement effects, rich surface binding properties, high surface-to-volume ratios, broad and intense absorption spectra in the visible region, and low cost as well, QDs offer new and versatile ways to serve as photocatalysts for organic synthesis. Most recently, the use of QDs photocatalysts is springing up in organic synthesis. Herein, we highlight the recent advances of QDs used for smart and clean organic transformations. PMID- 29575191 TI - Synergistic anti-oomycete effect of melatonin with a biofungicide against oomycetic black shank disease. AB - Human health, food safety, and agriculture have been threatened by oomycetic diseases caused by notorious pathogenic oomycetes. Chemical oomyceticides are the main approaches in control of pathogenic oomycetes. However, the overused chemical oomyceticides have resulted in serious environmental pollution and drug resistance. The eco-friendly bio-oomyceticides are required for sustainable development through screening synergistic drug combinations. In this study, Phytophthora nicotianae (P. nicotianae), as one of the most destructive oomycetic diseases in agriculture, was used as a model system to screen the novel bio oomyceticides based on drug combination. The results showed that treatment of melatonin or ethylicin (IUPAC Name: 1-ethylsulfonylsulfanylethane) alone displayed similar phenotypes such as the inhibition of the hyphal growth, reduction of the cell viability, and suppression of the virulence of P. nicotianae. Importantly, melatonin and ethylicin shared the same targets of interfering with the amino acid metabolism, overexpressing apoptosis-inducing factor, and dysregulating the virulence-related genes. Furthermore, strong synergism against P. nicotianae was induced by combining melatonin with ethylicin. Under treatment of the combination of melatonin and ethylicin, the expression of genes associated with amino acid, the apoptosis-inducing factor, and the virulence-related genes was much more significantly dysregulated than that of single drug treatment. Thus, the tobacco black shank caused by P. nicotianae can be successfully controlled using the combination of melatonin and ethylicin. These observations suggest that the synergistic effect based on the combination of melatonin and ethylicin is an eco-friendly alternative for the control of the destructive oomycetic diseases. PMID- 29575194 TI - Hidradenitis suppurativa in children: The Henry Ford experience. AB - BACKGROUND: Although recent hidradenitis suppurativa studies have shown that early-onset disease is associated with a positive family history and more widespread disease, research in pediatric hidradenitis suppurativa is limited. METHODS: Thirty-three children diagnosed with hidradenitis suppurativa during an 18-month period were included in this institutional review board-approved, retrospective chart review. Information on demographic characteristic, family history, and timing of onset (prepubescent vs postpubescent) was extracted. The Fisher exact test, Cochran-Armitage exact trend test, and chi-square test were used to examine the association between prepubescent or postpubescent onset of hidradenitis suppurativa and sex, disease severity, and family history. RESULTS: A significantly higher percentage of patients with postpubescent onset were female (85.7%) than male (14.3%), whereas those with prepubescent onset were more likely to be male (58.3%) than female (41.7%; P = .02). Associations between disease onset and positive family history of hidradenitis suppurativa (P = .47) or higher Hurley stage of disease (P = .15) were not statistically significant. CONCLUSION: Boys are more likely to have prepubescent onset of hidradenitis suppurativa and girls to have postpubescent onset. This shift in sex distribution is unexplained, but we hypothesize that, whereas the role of ovarian hormones in the pathogenesis of HS may underlie much of adult-onset disease, it is less important in prepubescent disease. PMID- 29575193 TI - Synaptic organization of the dorsal lateral geniculate nucleus. AB - A half century after Ray Guillery's classic descriptions of cell types, axon types, and synaptic architecture of the dorsal lateral geniculate nucleus, the functional organization of this nucleus, as well as all other thalamic nuclei, is still of enormous interest. This review will focus on two classic papers written by Ray Guillery: 'A study of Golgi preparations from the dorsal lateral geniculate nucleus of the adult cat', and 'The organization of synaptic interconnections in the laminae of the dorsal lateral geniculate nucleus of the cat', as well as the studies that most directly followed from the insights these landmark manuscripts provided. It is hoped that this review will honor Ray Guillery by encouraging further investigations of the synaptic organization of the dorsal thalamus. PMID- 29575195 TI - Ethnopharmacology, phytochemistry, and biotechnological advances of family Apocynaceae: A review. AB - The family Apocynaceae is one of the largest and important families in angiosperm. Several members of this family have medicinal properties and have been in the treatment of various ailments. Most of them are consumed as food by tribal people whereas a few plants are used as source of poison. Members of family Apocynaceae are rich in alkaloids, terpenoids, steroids, flavonoids, glycosides, simple phenols, lactones, and hydrocarbons. Other compounds such as sterols, lignans, sugars, lignans, and lactones have been isolated and systematically studied. Few studies have reported antioxidant, anti-inflammatory, antimicrobial, and cytotoxic activities of crude extracts as well as single compound(s) isolated from various members of the family Apocynaceae. Holarrhena antidysenterica, Rauvolfia serpentina, Carissa carandas, and Tabernaemontana divaricata are the extensively studied plants in this family. The present review provides a detailed outlook on ethnopharmacology, phytochemistry, and biological activities of selected members of this family. Moreover, it also covers the biotechnological advances used for large-scale production of bioactive compounds of therapeutic interest along with plant tissue culture-based approaches for conservation of this medicinally valuable family. PMID- 29575196 TI - Granulocyte and monocyte CD11b expression during plasma separation is dependent on complement factor 5 (C5) - an ex vivo study with blood from a C5-deficient individual. AB - The aim of the study was to investigate the role of complement factor 5 (C5) in reactions elicited by plasma separation using blood from a C5-deficient (C5D) individual, comparing it to C5-deficient blood reconstituted with C5 (C5DR) and blood from healthy donors. Blood was circulated through an ex vivo plasma separation model. Leukocyte CD11b expression and leukocyte-platelet conjugates were measured by flow cytometry during a 30-min period. Other markers were assessed during a 240-min period. Granulocyte and monocyte CD11b expression did not increase in C5D blood during plasma separation. In C5DR samples granulocytes CD11b expression, measured by mean fluorescence intensity (MFI), increased from 10481 +/- 6022 (SD) to 62703 +/- 4936, and monocytes CD11b expression changed from 13837 +/- 7047 to 40063 +/- 713. Granulocyte-platelet conjugates showed a 2.5-fold increase in the C5DR sample compared to the C5D sample. Monocyte platelet conjugates increased independently of C5. In the C5D samples, platelet count decreased from 210 * 109 /L (201-219) (median and range) to 51 * 109 /L (50 51), and C3bc increased from 14 CAU/mL (21-7) to 198 CAU/mL (127-269), whereas TCC formation was blocked during plasma separation. In conclusion, up-regulation of granulocyte and monocyte CD11b during plasma separation was C5-dependent. The results also indicate C5 dependency in granulocyte-platelet conjugates formation. PMID- 29575198 TI - Down-regulation of microRNA-19b in hormone receptor-positive/HER2-negative breast cancer. AB - miR-19b (miR-19b-3p) has been reported to be correlated with either favorable or unfavorable events in several cancers. However, no study has been conducted to evaluate the expression level of miR-19b in patients with breast cancer (BC). This study was aimed to investigate the expression level of miR-19b in human malignant and healthy breast tissues with histopathology of ER+/PR+/HER2-. We performed a miRNA real-time PCR to detect differential expression of miR-19b in 40 BC, including 17 BC with familial background and 23 BC without familial background, and 12 non-tumoral tissues. Moreover, a bioinformatics prediction upon miR-19b functionality in BC cells was performed. The miR-19b expression level was significantly down-regulated in BC, BC with familial background, and BC without familial background compared with its expression in normal tissue (p value, <0.0001; fold change, -7.45; p value, 0.0003; fold change, -6.45; and p value, 0.0005; fold change, -8.41, respectively). Moreover, according to the AUCs (area under curve) of receiver operating characteristic (ROC) curves, miR-19b can significantly distinguish all defined categories. Last, in agreement with our experimental findings, proteoglycans in cancer, pathways in cancer, FoxO signaling pathway, central carbon metabolism in cancer, p53 signaling pathway, transcriptional misregulation in cancer, and prolactin signaling pathway were predicted as miR-19b-related signaling pathways. In summary, down-regulation of miR-19b in BC vs healthy tissue suggests that mir-19b can function as a tumor suppressor. Our results shed additional information on controversial expression pattern of miR-19b depending on different cancer types. PMID- 29575197 TI - PTTG-1 (Securin) immunoexpression in meningiomas correlates with tumor grade and proliferation rate: potential use as a diagnostic marker of malignancy. AB - This study essentially aims to contribute to the immunohistochemical investigation of the use of pituitary tumor transforming gene (PTTG) as a marker of cell proliferation or advanced tumor grade in meningiomas of various WHO grades. In all, 51 cases were recovered in total, 21 Grade-I, 23 Grade-II and 7 Grade-III meningiomas. Mitotic index (MI), Ki-67/MiB-1 positivity percentage and PTTG expression were analyzed in correlation to each other as well as to the tumor WHO grades. All three biomarkers showed a high diagnostic significance and a strong association with WHO grades. In comparison, PTTG expression was on a par with the other two indices, and performed very well regarding identification of advanced grade tumors. PTTG may be considered an important diagnostic tool and serve in the future as a novel prognosticator of the biological behavior of all grade meningiomas as well as a useful high-risk patient selection tool. PMID- 29575199 TI - Effect of matrix metalloproteinase-21 (572C/T) polymorphism on HIV-associated neurocognitive disorder. AB - Remodeling of extracellular matrix (ECM) by matrix metalloproteinases (MMPs) is a presumed reason for the development of HIV-associated neurocognitive disorders (HAND). The coding region polymorphism in MMP-21 572C/T gene may have a potential functional effect on ECM remodeling. Hence, we aimed to examine the association of MMP-21 polymorphism with the modulation of HAND severity and its prevalence in HIV-infected and healthy individuals. Genotyping of MMP-21 572C/T polymorphism was performed by PCR-RFLP in total 150 HIV-infected individuals, 50 with HAND, 100 without HAND and 150 healthy controls. MMP-21 572TT genotype was predominantly higher in HAND patients compared with no HAND (OR = 1.63, p = 0.57). MMP-21 572T allele was associated with reduce risk for HAND severity (OR = 0.50, p = 0.04). Similarly, MMP-21 572TT genotype underrepresented in HIV infected individuals compared to healthy controls (3.0% vs 6.7%, OR = 0.27, p = 0.08). MMP-21 572CT genotype and early HIV disease stage showed a higher risk for the advancement of HIV disease with marginal significance (OR = 1.89, p = 0.07). MMP-21 572CT genotype increased the risk for the modulation of HAND severity in tobacco users (OR = 1.98, p = 0.43). MMP-21 572CT genotype among tobacco and alcohol users showed elevated risk for the development of HAND in HIV-infected individuals (OR = 2.30, p = 0.15; OR = 1.86, p = 0.23). Similarly, MMP-21 572TT genotype enhanced the risk for the development of HAND in tobacco users (OR = 3.48, p = 0.40). In conclusion, the presence of coding region 572T allele may have protection for HAND severity. MMP-21 572C/T polymorphism and tobacco and alcohol usage may facilitate the development of HAND. PMID- 29575200 TI - Oxidative stress in normal hematopoietic stem cells and leukemia. AB - Leukemia is developed following the abnormal proliferation of immature hematopoietic cells in the blood when hematopoietic stem cells lose the ability to turn into mature cells at different stages of maturation and differentiation. Leukemia initiating cells are specifically dependent upon the suppression of oxidative stress in the hypoglycemic bone marrow (BM) environment to be able to start their activities. Relevant literature was identified by a PubMed search (2000-2017) of English-language literature using the terms 'oxidative stress,' 'reactive oxygen species,' 'hematopoietic stem cell,' and 'leukemia.' The generation and degradation of free radicals is a main component of the metabolism in aerobic organisms. A certain level of ROS is required for proper cellular function, but values outside this range will result in oxidative stress (OS). Long-term overactivity of reactive oxygen species (ROS) has harmful effects on the function of cells and their vital macromolecules, including the transformation of proteins into autoantigens and increased degradation of protein/DNA, which eventually leads to the change in pathways involved in the development of cancer and several other disorders. According to the metabolic disorders of cancer, the relationship between OS changes, the viability of cancer cells, and their response to chemotherapeutic agents affecting this pathway are undeniable. Recently, studies have been conducted to determine the effect of herbal agents and cancer chemotherapy drugs on oxidative stress pathways. By emphasizing the role of oxidative stress on stem cells in the incidence of leukemia, this paper attempts to state and summarize this subject. PMID- 29575201 TI - Sebaceous carcinoma of the breast in a patient with a pathogenic BRCA2 (886delGT) mutation - focus on histopathologic and immunohistochemical features. AB - Sebaceous carcinoma of the breast (SCB) is a rare variant of ductal carcinoma arising within the mammary gland and containing at least 50% of malignant cells with sebaceous differentiation. Only 11 cases that adjust to the criteria delineated in the WHO classification have been published in the English literature, to the best of our knowledge. Here, we present the first SCB arising in the context of a deleterious BRCA2 mutation, focusing on the histopathologic and immunohistochemical features of this exceedingly rare tumor. PMID- 29575202 TI - Sliding sign in third-trimester sonographic evaluation of intra-abdominal adhesions in women undergoing repeat Cesarean section: a novel technique. AB - OBJECTIVE: Intra-abdominal adhesions are associated with an increased risk of complications during repeat Cesarean section (CS), such as bladder and bowel injury, hemorrhage, infection and hysterectomy. We present a simple sonographic marker, the 'sliding sign' of the uterus, for the prediction of intra-abdominal adhesions in the third trimester of pregnancy in women undergoing repeat CS. METHODS: This was a prospective observational study of pregnant women with a history of at least one Cesarean delivery evaluated by transabdominal ultrasound during the third trimester of an ongoing pregnancy. In order to diagnose intra abdominal adhesions, we assessed a sonographic sign, the sliding of the uterus under the inner part of the fascia of the abdominal muscles during deep breathing. Women were considered to be at high risk for severe adhesions if uterine sliding was absent and at low risk in the presence of obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions observed during surgery was performed. RESULTS: Of the 63 patients with one or more previous CS examined, 59 completed the study and underwent CS at our institution. In 16 of the 19 cases assigned to the high-risk group for severe adhesions due to absence of sliding of the uterus, the suspicion was confirmed at surgery. The prediction of low risk for adhesions was confirmed in 35 out of 40 patients. The sensitivity and specificity of the sliding sign in predicting presence of intra-abdominal adhesions in women undergoing repeat CS were 76.2% and 92.1%, respectively. Inter- and intraobserver correlation using Cohen's kappa coefficient were 0.52 and 0.77, respectively. CONCLUSION: Our data show that a simple sonographic sign might be able to discriminate between high and low risk for intra-abdominal adhesions in patients with a history of Cesarean delivery. This technique may aid clinical decisions in patients undergoing repeat CS. Copyright (c) 2018 ISUOG. Published by John Wiley & Sons Ltd. PMID- 29575203 TI - Glucocorticoids inhibit notch target gene expression in osteoblasts. AB - Glucocorticoids in excess suppress osteoblast function and cause osteoporosis. We demonstrated that cortisol induces the expression of selected Notch receptors in osteoblasts, revealing a potential mechanism for the skeletal effects of glucocorticoids. However, it remains to be determined whether increased expression of Notch receptors results into enhanced signaling. Following activation of Notch, its intracellular domain (NICD) binds to the DNA-associated protein recombination signal binding protein for immunoglobulin kappa-J region (RBPJ) and induces the expression of target genes such as Hey1, Hey2, and HeyL. To determine whether glucocorticoids modulate Notch signaling in the skeleton, 1 month old wild-type mice were administered prednisolone or placebo and sacrificed after 72 h, and gene expression was analyzed in femoral bone. Prednisolone induced Tsc22d3, a glucocorticoid target gene, and suppressed Hey1 and HeyL expression, which is indicative of inhibited Notch receptor activity or direct Hey downregulation. To determine the mechanisms of Hey suppression, wild-type osteoblast-enriched cells were seeded on the Notch cognate ligand Delta-like (DLL)1 or transfected with constructs expressing the NOTCH1 NICD fragment and exposed to either cortisol or vehicle. Cortisol opposed the induction of mRNA and heterogeneous nuclear RNA for Hey1, Hey2, and HeyL by DLL1, but had no effect on mRNA stability, indicating that glucocorticoids inhibit Hey expression by transcriptional mechanisms. Transactivation studies and electrophoretic mobility shift assays revealed that cortisol did not oppose RBPJ-mediated transcription or RBPJ/DNA interactions, respectively. In conclusion, glucocorticoids suppress expression of Hey1, Hey2, and HeyL in osteoblasts by RBPJ-independent transcriptional mechanisms. PMID- 29575204 TI - The adoption of care robots in home care-A survey on the attitudes of Finnish home care personnel. AB - AIMS AND OBJECTIVES: This article examines the attitudes of Finnish home care registered nurses, licensed vocational nurses and other health and social care personnel towards the introduction and use of care robots in home care. BACKGROUND: The significance of care robotics has been highlighted in recent years. However, personnel-related social psychological barriers to the introduction of care robots have been given very little study. DESIGN: Cross sectional study conducted by questionnaire. The theoretical framework of the study is based on Ajzen's theory of planned behaviour and the research discussion about attitudes towards robots. METHODS: The research data were collected in five municipalities in different parts of Finland in 2016, and the questionnaire was answered by a total of 200 home care workers. The research data were analysed using exploratory factor analysis, Pearson product-moment correlation, one-way analysis of variance and linear regression analysis. RESULTS: The results are consistent with Ajzen's theory and previous studies on the acceptance of information systems in health care. Personnel behavioural intentions related to the introduction of robot applications in home care are influenced by their personal appreciation of the usefulness of robots, the expectations of their colleagues and supervisors, as well as by their own perceptions of their capacity to learn to use care robots. In particular, personnel emphasised the value of care robots in providing reminders and guidance, as well as promoting the safety of the older people. CONCLUSIONS: The study shows that an intimate human-robot relationship can pose a challenge from the perspective of the acceptance of care robots. RELEVANCE TO CLINICAL PRACTICE: From the perspective of the introduction of care robots in home care, personnel training and the construction of a positive working atmosphere play a key role. In addition, the introduction of robots requires further consideration of a number of ethical issues. PMID- 29575205 TI - Estimate of choline nutritional requirements for chicks from 1 to 21 days of age. AB - Choline is an essential nutrient in poultry diets because it performs various important metabolic functions. The objective of this study was to re-evaluate the choline requirements of male broiler chickens from 1 to 21 days of age at two levels of methionine. Two assays using 2,160 Cobb(r) chickens (1,080 in each assay) were conducted. The study design was completely randomized and consisted of six treatments and six replicates, with 30 animals per experimental unit. The semipurified basal diet was formulated with corn, soya bean meal, soya protein concentrate, starch and sugar, providing 390 mg/kg choline and 0.593% digestible methionine (requirement level) in Assay 1 and a reduction of about one-quarter in the requirement level of digestible methionine (0.440%) in Assay 2. Choline chloride (62.5%) was added by a supplementation technique to both basal diets to compose crescent levels of choline supplementation (715, 1,040, 1,365, 1,690 and 2,015 mg/kg). The weight gain responses were fitted using quadratic polynomial (QP) and broken-line (BL) models. The ideal intake of choline (mg/bird.day) was estimated from the first intercept of the QP with the BL plateau (BL + QP). The results showed that the diet with the 25% reduction in digestible methionine limited the maximum weight gain by approximately 10%. The choline requirements of broilers from 1 to 7, 1 to 14 and 1 to 21 days of age were 27,013, 44,458 and 62,535 mg/bird.day, respectively, for the requirement level of digestible methionine and 26,796, 41,820 and 56,578 mg/bird.day for the broilers receiving the diet with the 25% reduction in digestible methionine. PMID- 29575206 TI - The fasciacytes: A new cell devoted to fascial gliding regulation. AB - Hyaluronan occurs between deep fascia and muscle, facilitating gliding between these two structures, and also within the loose connective tissue of the fascia, guaranteeing the smooth sliding of adjacent fibrous fascial layers. It also promotes the functions of the deep fascia. In this study a new class of cells in fasciae is identified, which we have termed fasciacytes, devoted to producing the hyaluronan-rich extracellular matrix. Synthesis of the hyaluronan-rich matrix by these new cells was demonstrated by Alcian Blue staining, anti-HABP (hyaluronic acid binding protein) immunohistochemistry, and transmission electron microscopy. Expression of HAS2 (hyaluronan synthase 2) mRNA by these cells was detected and quantified using real time RT-PCR. This new cell type has some features similar to fibroblasts: they are positive for the fibroblast marker vimentin and negative for CD68, a marker for the monocyte-macrophage lineage. However, they have morphological features distinct from classical fibroblasts and they express the marker for chondroid metaplasia, S-100A4. The authors suggest that these cells represent a new cell type devoted to the production of hyaluronan. Since hyaluronan is essential for fascial gliding, regulation of these cells could affect the functions of fasciae so they could be implicated in myofascial pain. Clin. Anat. 31:667-676, 2018.

PMID- 29575208 TI - The rural mother's experience of caring for a child with a chronic health condition: An integrative review. AB - AIMS AND OBJECTIVES: To identify and review the literature on rural mothers' experiences in caring for a child with a chronic health condition. BACKGROUND: Families living with a child who has a chronic health condition experience many challenges; these are often amplified for families living in rural areas, where issues such as the distance from services add further challenges the family must manage. Like many children, rural children with chronic health conditions are primarily cared for by their mothers. The additional strain of geography creates its own unique experiences for mothers who need to access the high-quality care that their child requires. DESIGN: Integrative literature review using the Equator PRISMA guidelines. METHODS: A search of databases; Cochrane, CINAHL, Ovid, PubMed, ProQuest Health and Medicine, Informit and Scopus for studies published between 2005-2016 using an integrative review approach. A total of 1,484 studies were identified with an additional six studies found through snowballing. The search resulted in seven studies being meeting the inclusion criteria after using the Critical Appraisal Skills Programme. RESULTS: Data from the seven articles were analysed, and the mothers' experiences were synthesised into five themes: "struggling for resources," "barriers in accessing services," "strain of decision-making," "mother's physical and emotional breakdown" and "the daily management of family activities". These five themes formed the basis of this article. CONCLUSIONS: The findings indicate that mothers from rural areas face additional barriers related to their rurality, including transportation difficulties, socioeconomic status and social isolation, and are challenged by limited access to specialty medical services, educators and allied health professionals. The literature review outcome will assist in informing nursing practice through identifying and allocating resources to reduce these barriers; rural mother experience will assist in enabling the child to reach their full developmental potential. RELEVANCE TO CLINICAL PRACTICE: There is a need for health professionals to understand the challenges and barriers rural mothers face in accessing services. Nurses can assist rural mothers to navigate and access the appropriate services in order to reduce health inequity, increase accessibility to services and reduce rural disadvantage for their child. Nurses and health professionals are in an ideal position to develop future models of care that optimise health outcomes and enable equity and access to services for rural children with chronic conditions similar to those experienced by their urban counterparts. PMID- 29575209 TI - Rapid Oligonucleotide Drug Impurity Determination by Direct Spectral Comparison of Ion Pair-Reversed Phase HPLC ESI MS Data. AB - RATIONALE: Quantitative Ion-Pair (IP)-HPLC MS methods are employed to determine the complex impurity profiles of oligonucleotide therapeutics. While impurities that co-elute with the main product are routinely monitored, the large number of early and late eluting impurities makes their individual measurements tedious and time-consuming. An improved method is needed for routine analyses. METHODS: A Combined Ranking (CR) index is developed to provide a composite value for both qualitative and quantitative impurity changes. Positive and Negative Impurity Change (PIC/NIC) indices are developed to determine the degree and direction of change. Optimized experimental conditions are determined for the characterization of trace levels of impurities. Replicate analysis, blank subtraction, and signal processing approaches are used to enhance the S/N. Dot-product and Euclidean distance equations monitor spectral changes. RESULTS: Spiking experiments with individual and complex impurity mixtures show the method can distinguish among samples differing in impurity content by 0.2% wt. The method has been applied to monitor changes in impurity profile among different batches of the same oligonucleotide and changes in the same batch over time (stability analysis). The method permits rapid determination of changes in the types and amounts (increases and decreases) of impurities present. CONCLUSIONS: A novel approach for the rapid determination of changes in the impurity profile of oligonucleotide therapeutics has been developed. The straightforward data treatment and the speed and simplicity of the approach make the method easy to implement and use. Possible quality control applications include drug substance and drug product stability studies, and the assessment of batch-to-batch variability. PMID- 29575210 TI - Delivering cognitive behavioural therapy to advanced cancer patients: A qualitative exploration into therapists' experiences within a UK psychological service. AB - BACKGROUND: Cognitive behavioural therapy (CBT) is commonly used to treat cancer patients with psychological disorders such as depression. There has been little qualitative research exploring the experience of therapists delivering CBT to patients with advanced cancer and long-term health conditions generally. Therapists' views may help identify difficulties in delivering therapy and how these may be overcome. The aim of this study was to inform practice by qualitatively exploring the experiences of therapists delivering CBT to patients with advanced cancer. DESIGN: Sixteen semi-structured interviews were conducted with therapists from Increasing Access to Psychological Therapy (IAPT) services in London, UK, who had delivered CBT to patients enrolled on the CanTalk trial. Interviews were recorded, transcribed, and analysed using framework analysis. RESULTS: Therapists reported positive experiences when working with the target population. Flexibility, adaptability, and a consideration of individual needs were identified as important when delivering CBT, but the rigidity of IAPT policies and demand for services were perceived as problematic. Although therapists reported adequate training, specialist supervision was desired when delivering therapy to this complex population. CONCLUSION: IAPT therapists can deliver CBT to advanced cancer patients, given therapists positive experiences evident in the present study. However, it was concluded that additional service and modifications of therapy may be needed before positive outcomes for both therapists and patients can be achieved. PMID- 29575211 TI - GSEA of mouse and human mitochondriomes reveals fatty acid oxidation in astrocytes. AB - The prevalent view in neuroenergetics is that glucose is the main brain fuel, with neurons being mostly oxidative and astrocytes glycolytic. Evidence supporting that astrocyte mitochondria are functional has been overlooked. Here we sought to determine what is unique about astrocyte mitochondria by performing unbiased statistical comparisons of the mitochondriome in astrocytes and neurons. Using MitoCarta, a compendium of mitochondrial proteins, together with transcriptomes of mouse neurons and astrocytes, we generated cell-specific databases of nuclear genes encoding for mitochondrion proteins, ranked according to relative expression. Standard and in-house Gene Set Enrichment Analyses (GSEA) of five mouse transcriptomes revealed that genes encoding for enzymes involved in fatty acid oxidation (FAO) and amino acid catabolism are consistently more expressed in astrocytes than in neurons. FAO and oxidative-metabolism-related genes are also up-regulated in human cortical astrocytes versus the whole cortex, and in adult astrocytes versus fetal astrocytes. We thus present the first evidence of FAO in human astrocytes. Further, as shown in vitro, FAO coexists with glycolysis in astrocytes and is inhibited by glutamate. Altogether, these analyses provide arguments against the glucose-centered view of energy metabolism in astrocytes and reveal mitochondria as specialized organelles in these cells. PMID- 29575212 TI - Association between cervical lordotic curvature and cervical muscle cross sectional area in patients with loss of cervical lordosis. AB - Disruption of the cervical lordotic curve can cause undesirable symptoms such as neck pain, and cord compression. The purpose of this study was to investigate the biomechanics of loss of cervical lordosis by measuring the cross-sectional area (CSA) of the cervical muscles using magnetic resonance imaging (MRI), and to determine the relationship between cervical lordosis angle and cervical muscle status. The cervical lordosis angle was measured on standing lateral plain radiography using the posterior tangent technique in patients who complained of neck pain. The CSAs of the cervical flexor muscles including the longus cervicis and longus capitis, the cervical extensor muscles including the splenius capitis and semispinalis capitis, and the sternocleidomastoid muscle, were measured at the maximum levels by axial T1-weighted MRI. We compared neck muscle CSAs between the two groups, the correlation with cervical lordosis angle, and muscle status including CSA and imbalance. The CSA of the semispinalis capitis was significantly lower in the loss of cervical lordosis group, and the ratio of cervical flexor to extensor was significantly different between the two groups (P < 0.05). Partial correlation analysis revealed that the cervical lordotic angle was significantly positively correlated with the ratio of flexor to extensor muscle CSAs (P < 0.05). There is a significant relationship between cervical muscle imbalance, including extensor muscle weakness, and loss of cervical lordosis. An exercise program focusing on cervical extensor muscle strengthening and restoring the balance of flexor and extensor muscles is recommended for patients with loss of cervical lordosis. Clin.

AB - BACKGROUND AND AIM: Little is known about the standard care of small (<2 cm in diameter) pancreatic neuroendocrine tumors (PNET). The aim of the present study was to determine the clinical outcomes of small PNET after endoscopic ultrasound (EUS)-guided ethanol-lipiodol ablation (EUS-ELA). METHODS: In this prospective cohort study, consecutive patients who underwent EUS-ELA for PNET were enrolled and were followed for >=3 years. Treatment efficacy was the primary outcome measure. RESULTS: In total, 33 patients who had 40 pathologically confirmed PNET (<2 cm in diameter) were enrolled for final analysis. A total of 63 EUS-ELA sessions were successfully carried out (mean, 1.9 sessions per patient, 1.6 sessions per tumor), which included 40 initial sessions and 23 repeated sessions owing to incomplete ablation. Median actual volume of ethanol-lipiodol mixture injected per session was 1.1 mL (IQR 0.8-1.9 mL). Complete ablation was achieved in 24 of 40 tumors (60%) with one (18 tumors, 45%) or two (24 tumors, 60%) sessions of EUS-ELA. Lipiodol retention within tumor had better treatment outcomes (P = 0.004). Rate of procedure-related adverse events was 3.2%. No malignancy or lymph node metastasis was discovered during a median follow up of 42 months (IQR 39-46 months). CONCLUSIONS: We found that EUS-ELA was a safe and effective alternative option in the management of PNET <2.0 cm in diameter; 60% of patients achieved complete ablation. Lipiodol retention within tumor may be a useful early predictor of treatment effectiveness. Trial registered at ClinicalTrials.gov (NCT 01902238). PMID- 29575214 TI - The relationship between process use and stage of change for sugary drinks. AB - BACKGROUND: Decreasing sugar-sweetened beverage consumption may reduce obesity and obesity-related diseases. To better understand what processes could facilitate a reduction in sugary beverage intake, we examined the relationship between stage-of-change and use of 10 processes of change. Secondarily, reliability of the measure was assessed. METHODS: A cross-sectional study was conducted, using a newly developed stage-of-change and process of change questionnaire. Participants (n = 105; male, n = 28) were aged between 18 and 60 years. A one-way analysis of variance, with Tukey's and Benjamini-Hochberg post hoc tests, was used to compare process use by stages. Paired t-tests were used to compare total cognitive and total behavioural process use within each stage. Cronbach's alpha coefficient and mean inter-item correlation was used to assess internal consistency. Reliability of repeated items was examined using kappa. RESULTS: Cognitive and behavioural processes were used more in the contemplation/preparation and maintenance stages than in precontemplation (all P < 0.05). Compared to precontemplation, process use was significantly higher in contemplation/preparation for five individual processes, action for four processes and maintenance for five processes. The use of dramatic relief and self liberation was lower in maintenance than contemplation/preparation. Across the stages, the use of eight of the 10 processes differed. The use of consciousness raising, self re-evaluation and self liberation differed between stages more frequently than other processes. CONCLUSIONS: The use of many processes differed by stage and could be incorporated into programmes aiming to assist adults in reducing their consumption of sugary drinks. PMID- 29575215 TI - Screening an elderly hearing impaired population for mild cognitive impairment using Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). AB - OBJECTIVES: To determine if there is an association between hearing loss and poorer cognitive scores on Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) and to determine if poor hearing acuity affects scoring on the cognitive screening tests of MMSE and MoCA. METHODS: One hundred fourteen elderly patients (Singapore residents) aged between 55 and 86 years were sampled. Participants completed a brief history questionnaire, pure tone audiometry, and 2 cognitive screening tests-the MMSE and MoCA. Average hearing thresholds of the better ear in the frequencies of 0.5, 1, 2, and 4 kHz were used for data analysis. RESULTS: Hearing loss was significantly associated with poorer cognitive scores in Poisson regression models adjusted for age. Mini-Mental State Examination scores were shown to decrease by 2.8% (P = .029), and MoCA scores by 3.5% (P = .013) for every 10 dB of hearing loss. Analysis of hearing-sensitive components of "Registration" and "Recall" in MMSE and MoCA using chi-square tests showed significantly poorer performance in the hearing loss group as compared to the normal hearing group. Phonetic analysis of target words with high error rates shows that the poor performance was likely contributed by decreased hearing acuity, on top of a possible true deficit in cognition in the hearing impaired. CONCLUSIONS: Hearing loss is associated with poorer cognitive scores on MMSE and MoCA, and cognitive scoring is likely confounded by poor hearing ability. This highlights an important, often overlooked aspect of sensory impairment during cognitive screening. Provisions should be made when testing for cognition in the hearing-impaired population to avoid over-referral and subsequent misdiagnoses of cognitive impairment.

AB - During the early 1970s Denise Kandel and her colleagues documented an 'invariant sequence' in initiation of drug use: starting with alcohol and tobacco, progressing to cannabis and then to other illicit, or 'harder' drugs. This observation, which became known as the 'gateway sequence' of drug use, has been influential in policy debates but remains highly contentious, with the area of greatest controversy focusing upon whether cannabis use increases risk causally for initiation of other illicit drugs. While numerous studies have replicated Kandel's initial findings (sequence of onset) and reported that associations between cannabis use and the use of other illicit drugs remain after controlling for potentially confounding factors, the mechanisms underlying these observed associations remain hotly debated. In particular, it is possible that the observed associations are non-causal but reflect the influence of confounding factors which influence both early-onset drug use and subsequent progressions. However, research employing a range of techniques to address this issue has been unable to discount the possibility that associations between earlier and subsequent drug use reflect causal processes. This paper reviews Kandel's ongoing contributions to this field, which span 45 years, and discusses both the influence of her work and the controversy that it has aroused. PMID- 29575219 TI - The history of the Society of Urodynamics, Female Pelvic Medicine, and Urogenital Reconstruction. AB - AIMS: To review the history of the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (SUFU). METHODS: We reviewed Society meeting minutes, contacted all living former Society presidents, searched the William P. Didusch Center for Urology History records, and asked Society members to share their important Society experiences in order to gather important historical information about the Society. RESULTS: The Society initially formed as the Urodynamics Society in 1969 in the backdrop of a growing passion for scientific research in the country after World War II ended. Since then, Society meetings have provided a pivotal forum for the advancement of science in lower urinary tract dysfunction. Meetings occurred annually until 2004, when the meeting schedule increased to biannual. The journal, Neurourology and Urodynamics, became the official journal of the Society in 2005. SUFU has authored important guidelines on urodynamics (2012), non-neurogenic overactive bladder (2012), and stress urinary incontinence (2017) and has shared important collaborations with other societies, including the American Urological Association (AUA), the International Continence Society (ICS), and the International Society of Pelvic Neuromodulation (ISPiN). SUFU has also been instrumental in trainee education and helped to establish formal fellowship training in the field in addition to holding a yearly educational meeting for urology residents. The Society has been led by 21 presidents throughout its history. CONCLUSION: Throughout the Society's near half-century long existence, the Society has fostered research, published guidelines, and educated trainees in order to improve the care of individuals suffering from lower urinary tract dysfunction.

AB - Disorders affecting the lumbosacral plexus (LSP) can alter root diameter. Our aim was to determine normal LSP nerve root dimensions using magnetic resonance neurography (MRN). Eleven asymptomatic patients (ages: 18-53, mean: 34 years) underwent MRN of the LSP on a 3 T scanner with an 8-channel torso-PA coil. IDEAL T2-weighted images were acquired and nerve root dimensions were measured from the second lumbar (L2) to the first sacral (S1) vertebrae on the coronal plane, 5 mm from the dorsal root ganglion (DRG). Root size was recorded by three separate groups of radiologists with different levels of expertise. Additional LSP-MRN images were acquired from a fresh-frozen cadaver specimen using the same scanner and parameters identical to those described above. Subsequently, two experienced anatomists dissected and measured the LSP roots at exactly the same distance from the DRG, using an electronic caliper. Mean root size values recorded (+/- standard deviation) in the asymptomatic patients were as follows: L2: 3.12 mm (+/ 0.92), L3: 4.29 mm (+/-0.95), L4: 5.13 mm (+/-0.79), L5: 5.29 mm (+/-0.9), and S1: 5.38 mm (+/-0.7). The correlation coefficients were 0.72 between the patient and cadaver MRN results and 0.79 between the patient and dissected cadaver MRN results. Inter-observer agreements were 0.73 among the radiologist groups and 0.87 between the anatomists conducting dissections. We believe MRN provides reliable assessments of LSP root thickness. More extensive studies should be conducted to confirm the results described here. Clin. Anat. 31:782-787, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29575221 TI - Arginine side chain stacking with peptide plane stabilizes the protein helix conformation in a cooperative way. AB - A combined experimental and computational study is performed for arginine side chain stacking with the protein alpha-helix. Theremostability measurements of Aristaless homeodomain, a helical protein, suggest that mutating the arginine residue R106, R137 or R141, which has the guanidino side chain stacking with the peptide plane, to alanine, destabilizes the protein. The R-PP stacking has an energy of ~0.2-0.4 kcal/mol. This stacking interaction mainly comes from dispersion and electrostatics, based on MP2 calculations with the energy decomposition analysis. The calculations also suggest that the stacking stabilizes 2 backbone-backbone h-bonds (i->i-4 and i-3->i-7) in a cooperative way. Desolvation and electrostatic polarization are responsible for cooperativity with the i->i-4 and i-3->i-7 h-bonds, respectively. This cooperativity is supported by a protein alpha-helices h-bond survey in the pdb databank where stacking shortens the corresponding h-bond distances.

AB - A series of linear peptides with the general formula H-Glu(R1)-Glu(R2)-OH was subjected to cyclization under standard conditions. Formation of respective 2,5 diketopiperazines was accompanied by transformation of the N-terminal Glu(R1) to pyroglutamic acid residue. Even in the case R1 is an amino acid residue attached to the N-terminal gamma-carboxyl group, lactamization leads to its elimination. The observed reaction has not been reported so far in the literature. Correspondingly, an alternative route to Glu(R1)-Glu(R2)-containing 2,5 diketopiperazines was applied to improve the overall yields. PMID- 29575224 TI - Oral psoriasis and SIBO: is there a link? PMID- 29575225 TI - Peanut agglutinin specifically binds to a sperm region between the nucleus and mitochondria in tunicates and sea urchins. AB - Peanut agglutinin (PNA) is an established marker of the mammalian acrosome. However, we observed that PNA specifically binds to a unique intracellular structure alongside the nucleus in ascidian sperm. Here, we characterize the PNA binding structure in sperm of marine invertebrates. PNA bound to the region between the mitochondrion and nucleus in spermatozoa of ascidians, sea urchins, and an appendicularian. However, PNA-binding substances were not exposed by the calcium ionophore ionomycin in three ascidian species, indicating that it is a distinct structure from the acrosome. Instead, the ascidian PNA-binding region was shed with the mitochondrion from the sperm head via an ionomycin-induced sperm reaction. The ascidian PNA-binding substance appeared to be solubilized with SDS, but not Triton X-100, describing its detergent resistance. Lectins, PHA L4 , SSA, and MAL-I were detected at an area similar to the PNA-binding region, suggesting that it contains a variety of glycans. The location and some of the components of the PNA-binding region were similar to known endoplasmic reticulum (ER)-derived structures, although the ER marker concanavalin A accumulated at an area adjacent to but not overlapping the PNA-binding region. Therefore, we conclude that ascidian sperm possess a non-acrosomal, Triton-resistant, glycan rich intracellular structure that may play a general role in reproduction of tunicates and sea urchins given its presence across a wide taxonomic range.

AB - PURPOSE: Co-prescription of paroxetine/fluoxetine (a strong CYP2D6 inhibitor) in metoprolol (a CYP2D6 substrate) users is common, but data on the clinical consequences of this drug-drug interaction are limited and inconclusive. Therefore, we assessed the effect of paroxetine/fluoxetine initiation on the existing treatment with metoprolol on the discontinuation and dose adjustment of metoprolol among elderly. METHODS: We performed a cohort study using the University of Groningen IADB.nl prescription database (www.IADB.nl). We selected all elderly (>=60 years) who had ever been prescribed metoprolol and had a first co-prescription of paroxetine/fluoxetine, citalopram (weak CYP2D6 inhibitor), or mirtazapine (negative control) from 1994 to 2015. The exposure group was metoprolol and paroxetine/fluoxetine co-prescription, and the other groups acted as controls. The outcomes were early discontinuation and dose adjustment of metoprolol. Logistic regression was applied to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Combinations of metoprolol paroxetine/fluoxetine, metoprolol-citalopram, and metoprolol-mirtazapine were started in 528, 673, and 625 patients, respectively. Compared with metoprolol citalopram, metoprolol-paroxetine/fluoxetine was not significantly associated with the early discontinuation and dose adjustment of metoprolol (OR = 1.07, 95% CI:0.77-1.48; OR = 0.87, 95% CI:0.57-1.33, respectively). In comparison with metoprolol-mirtazapine, metoprolol-paroxetine/fluoxetine was associated with a significant 43% relative increase in early discontinuation of metoprolol (OR = 1.43, 95% CI:1.01-2.02) but no difference in the risk of dose adjustment. Stratified analysis by gender showed that women have a significantly high risk of metoprolol early discontinuation (OR = 1.62, 95% CI:1.03-2.53). CONCLUSION: Paroxetine/fluoxetine initiation in metoprolol prescriptions, especially for female older patients, is associated with the risk of early discontinuation of metoprolol. PMID- 29575228 TI - Herbal medicines in the treatment of psychiatric disorders: 10-year updated review. AB - This paper provides a 10-year update of the 2007 systematic review of herbal medicines studied in a broad range of psychiatric disorders, including depression, anxiety, obsessive-compulsive, seasonal affective, bipolar, psychotic, phobic, somatoform, and attention-deficit hyperactivity disorders. Ovid Medline, PubMed, and the Cochrane Library were searched for herbal medicines with both pharmacological and clinical evidence of psychotropic activity. This updated review now covers clinical trial evidence for 24 herbal medicines in 11 psychiatric disorders. High-quality evidence was found to exist for the use of Piper methysticum (Kava), Passiflora spp. (passionflower) and Galphimia glauca (galphimia) for anxiety disorders; and Hypericum perforatum (St John's wort) and Crocus sativus (saffron) for major depressive disorder. Other encouraging herbal medicines with preliminary evidence include Curcuma longa (turmeric) in depression, Withania somnifera (ashwagandha) in affective disorders, and Ginkgo biloba (ginkgo) as an adjunctive treatment in Schizophrenia. Although depression and anxiety are commonly researched, many other mental disorders still require further prospective investigation. Although the previous review suggested increasing the adjunctive study of select herbal medicines with pharmaceuticals, this was still only found to sparingly occur in research designs. Aside from this, future focus should involve the incorporation of more biomarker analysis, in particular pharmacogenomics, to determine genetic factors moderating response to herbal medicines. PMID- 29575229 TI - Differential expression and prognostic value of long non-coding RNA in HPV negative head and neck squamous cell carcinoma. AB - BACKGROUND: Long non-coding RNA (lncRNA) has emerged as a new avenue of interest due to its various biological functions in cancer. Abnormal expression of lncRNA has been reported in other malignancies but has been understudied in head and neck squamous cell carcinoma (HNSCC). METHODS: The lncRNA expression was interrogated via quantitative real-time polymerase chain reaction (qRT-PCR) array for 19 human papillomavirus (HPV)-negative HNSCC tumor-normal pairs. The Cancer Genome Atlas (TCGA) was used to validate these results. The association between differentially expressed lncRNA and survival outcomes was analyzed. RESULTS: Differential expression was validated for 5 lncRNA (SPRY4-IT1, HEIH, LUCAT1, LINC00152, and HAND2-AS1). There was also an inverse association between MEG3 expression (not significantly differentially expressed in TCGA tumors but highly variable expression) and 3-year recurrence-free survival (RFS). CONCLUSION: We identified and validated differential expression of 5 lncRNA in HPV-negative HNSCC. Low MEG3 expression was associated with favorable 3-year RFS, although the significance of this finding remains unclear.

PMID- 29575231 TI - Phosphoproteomic profiling reveals ABA-responsive phosphosignaling pathways in Physcomitrella patens. AB - Abscisic acid (ABA) and its signaling system are important for land plants to survive in terrestrial conditions. Here, we took a phosphoproteomic approach to elucidate the ABA signaling network in Physcomitrella patens, a model species of basal land plants. Our phosphoproteomic analysis detected 4630 phosphopeptides from wild-type P. patens and two ABA-responsive mutants, a disruptant of group-A type-2C protein phosphatase (PP2C; ppabi1a/b) and AR7, a defective mutant in ARK, identified as an upstream regulator of SnRK2. Quantitative analysis detected 143 ABA-responsive phosphopeptides in P. patens. The analysis indicated that SnRK2 mediated phosphorylation and target motifs were partially conserved in bryophytes. Our data demonstrate that the PpSnRK2B and AREB/ABF-type transcription factors are phosphorylated in vivo in response to ABA under the control of ARK. On the other hand, our data also revealed the following: (i) the entire ABA-responsive phosphoproteome in P. patens is quite diverse; (ii) P. patens PP2C affects additional pathways other than the known ABA signaling pathway; and (iii) ARK is mainly involved in ABA signaling. Taken together, we propose that the core ABA signaling pathway is essential in all land plants; however, some ABA-responsive phosphosignaling uniquely developed in bryophytes during the evolutionary process. PMID- 29575232 TI - The impact of NarcotrendTM EEG-guided propofol administration on the speed of recovery from pediatric procedural sedation-A randomized controlled trial. AB - BACKGROUND: Propofol is often used for procedural sedation in children undergoing gastrointestinal endoscopy. Reliable assessment of the depth of hypnosis during the endoscopic procedure is challenging. Processed electroencephalography using the Narcotrend Index can help titrating propofol to a predefined sedation level. AIMS: The aim of this trial was to investigate the impact of Narcotrend Index guided titration of propofol delivery on the speed of recovery. METHODS: Children, aged 12-17 years, undergoing gastrointestinal endoscopy under procedural sedation, had propofol delivered via target controlled infusion either based on Narcotrend Index guidance (group NI) or standard clinical parameters (group C). Sedation was augmented with remifentanil in both study groups. The primary endpoint of this study was to compare the speed of fulfilling discharge criteria from the operating room between study groups. Major secondary endpoints were propofol consumption, discharge readiness from the recovery room, hypnotic depth as measured by the Narcotrend Index, and adverse events. RESULTS: Of the 40 children included, data were obtainable from 37. The time until discharge readiness from the operating room was shorter in group NI than in group C, with a difference between medians of 4.76 minutes [95%CI 2.6 to 7.4 minutes]. The same accounts for recovery room discharge times; difference between medians 4.03 minutes [95%CI 0.81 to 7.61 minutes]. Propofol consumption and the percentage of EEG traces indicating oversedation were higher in group C than in group NI. There were no significant adverse events in either study group. CONCLUSION: Narcotrend Index guidance of propofol delivery for deep sedation in children aged 12-17 years, underdoing gastrointestinal endoscopy results in faster recovery, less drug consumption, and fewer episodes of oversedation than dosing propofol according to clinical surrogate parameters of depth of hypnosis. The results of this study provide additional evidence in favor of the safety profile of propofol/remifentanil for procedural sedation in adequately selected pediatric patients.

PMID- 29575234 TI - 3D-Printing Electrolytes for Solid-State Batteries. AB - Solid-state batteries have many enticing advantages in terms of safety and stability, but the solid electrolytes upon which these batteries are based typically lead to high cell resistance. Both components of the resistance (interfacial, due to poor contact with electrolytes, and bulk, due to a thick electrolyte) are a result of the rudimentary manufacturing capabilities that exist for solid-state electrolytes. In general, solid electrolytes are studied as flat pellets with planar interfaces, which minimizes interfacial contact area. Here, multiple ink formulations are developed that enable 3D printing of unique solid electrolyte microstructures with varying properties. These inks are used to 3D-print a variety of patterns, which are then sintered to reveal thin, nonplanar, intricate architectures composed only of Li7 La3 Zr2 O12 solid electrolyte. Using these 3D-printing ink formulations to further study and optimize electrolyte structure could lead to solid-state batteries with dramatically lower full cell resistance and higher energy and power density. In addition, the reported ink compositions could be used as a model recipe for other solid electrolyte or ceramic inks, perhaps enabling 3D printing in related fields. PMID- 29575235 TI - Bone marrow or adipose tissue mesenchymal stem cells: Comparison of the therapeutic potentials in mice model of acute liver failure. AB - Acute liver failure (ALF) is a lethal disease with limited life-saving therapy. Because lack of whole organ donors for liver transplantation, a substitute treatment strategy is needed for these patients. Preclinical and clinical findings have proved that treatment with mesenchymal stem cells (MSCs) is beneficial for recovery from ALF. In this approach, however, the appropriate sources of these cells are unclear. In the present study, we investigated and compared the therapeutic potentials of bone marrow-mesenchymal stem cells (BM MSC) with those of adipose tissue (AT-MSC) in carbon tetrachloride (CCL4)-induced acute liver failure in mice. Murine BM- and AT-MSCs obtained from normal mice were cultured and labelled. The cells were transplanted to CCL4-induced ALF mice models intravenously. After cell transplantation, blood samples and liver tissues were collected daily for 72 h to analyze liver enzymes and liver histopathology, respectively. We found that survival rate of AT-MSC transplanted (AT-TR) mice was significantly higher than that of control (ALF) group. Liver histopathology was superior in the AT-TR mice, but not significantly, compared to that in BM-MSC transplanted (BM-TR) ones. Furthermore, in the AT-TR mice the level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), in some time points were significantly less than those of BM-TR. Taken together, these data suggest that in comparison to BM-MSC, AT-MSCs is an appropriate choice for cell therapy in the case of acute liver failure. PMID- 29575236 TI - DMC is not better than TMZ on intracranial anti-glioma effects. AB - Previous studies showed Demethoxycurcumin (DMC) has stronger anti-glioma and anti GSCs effects both in vitro and in vivo. In addition, DMC seems to be lower toxicity than TMZ on nude mice. However, this conclusion was confirmed to be wrong in this study. We have evaluated the antitumor efficacy of DMC or TMZ treatment by an orthotopic glioblastoma xenograft model. Nude mice were injected with U87MG-luc cells in the caudate nucleus of the brain and treated with DMC (30 mg/kg q.d.) or TMZ (10 mg/kg q.d.) by intraperitoneal injection. Bioluminescence imaging (BLI) was used to monitoring tumor growth and response to therapy. Western blot was used to detect the expression of p-Akt, cleaved-caspase-3 and Bax. The average value of BLI showed TMZ determined a significant tumor regression while DMC had a mild regression effect on tumor growth compared with control group. Immunohistochemistry for Ki67, proliferating cell nuclear antigen (PCNA), and TUNEL demonstrated that TMZ more effectively inhibited the expression of Ki67 and PCNA, and increased the ratio of TUNEL-positive cells in in situ tumor tissue. Western blot analysis also indicated that TMZ but not DMC more significantly decreased p-Akt and increased cleaved-caspase-3 and Bax expression.These findings suggested a fact that TMZ appear to be more effective in controlling the growth of glioblastoma than DMC in an orthotopic glioblastoma xenograft model. PMID- 29575237 TI - Improving Nelumbo nucifera genome assemblies using high-resolution genetic maps and BioNano genome mapping reveals ancient chromosome rearrangements. AB - Genetic and physical maps are powerful tools to anchor fragmented draft genome assemblies generated from next-generation sequencing. Currently, two draft assemblies of Nelumbo nucifera, the genomes of 'China Antique' and 'Chinese Tai zi', have been released. However, there is presently no information on how the sequences are assembled into chromosomes in N. nucifera. The lack of physical maps and inadequate resolution of available genetic maps hindered the assembly of N. nucifera chromosomes. Here, a linkage map of N. nucifera containing 2371 bin markers [217 577 single nucleotide polymorphisms (SNPs)] was constructed using restriction-site associated DNA sequencing data of 181 F2 individuals and validated by adding 197 simple sequence repeat (SSR) markers. Additionally, a BioNano optical map covering 86.20% of the 'Chinese Tai-zi' genome was constructed. The draft assembly of 'Chinese Tai-zi' was improved based on the BioNano optical map, showing an increase of the scaffold N50 from 0.989 to 1.48 Mb. Using a combination of multiple maps, 97.9% of the scaffolds in the 'Chinese Tai-zi' draft assembly and 97.6% of the scaffolds in the 'China Antique' draft assembly were anchored into pseudo-chromosomes, and the centromere regions along the pseudo-chromosomes were identified. An evolutionary scenario was proposed to reach the modern N. nucifera karyotype from the seven ancestral eudicot chromosomes. The present study provides the highest-resolution linkage map, the optical map and chromosome level genome assemblies for N. nucifera, which are valuable for the breeding and cultivation of N. nucifera and future studies of comparative and evolutionary genomics in angiosperms. PMID- 29575238 TI - Additive and synergistic inhibition of mantle cell lymphoma cell growth by combining olaparib with ibrutinib. AB - Mantle cell lymphoma (MCL) presents a therapeutic challenge. The B cell targeting agent, ibrutinib, is currently one of the most effective second-line therapies for MCL, but frequently leads to development of drug resistance, and short overall survival time upon relapse. Olaparib targets tumor cells with deficiencies in single-strand DNA break repair and thus may slow the development of genetic drug resistance. We found that the olaparib-ibrutinib combination significantly inhibits cell culture growth compared to either drug alone in two genetically distinct MCL cell lines. Moreover, these inhibitory effects are either additive or synergistic, depending on genetic background. Culture growth is inhibited due to increases in apoptosis, cell death, and cell cycle arrest, and the magnitude of each is cell line dependent. The additive and synergistic inhibition of this combination additionally supports a therapeutic strategy involving lower dosing of each drug to reduce potential side effects. PMID- 29575239 TI - An evaluation of serum gentamicin concentrations and bacterial susceptibility to gentamicin in equine practice. AB - BACKGROUND: Therapeutic drug monitoring and minimum inhibitory concentration (MIC) data allow more informed use of gentamicin. HYPOTHESIS/OBJECTIVES: To measure peak and trough serum gentamicin concentrations in horses after a 6.6 mg/kg dose of gentamicin given IV and the MIC of gentamicin of bacteria for which gentamicin might be selected. METHODS: Retrospective analysis of hospital records. Peak and trough plasma gentamicin concentrations were measured after 6.6 mg/kg gentamicin IV in 339 hospitalized horses. The MIC of gentamicin was measured for 503 isolates from ambulatory practice and 33 from hospital practice. The distribution of gentamicin concentrations and MIC results were compared to current recommendations for MIC breakpoints. RESULTS: The median serum gentamicin concentration at 60 minutes after administration (C60min ) was 21.4 MUg/mL with a distribution indicating that bacteria with MIC >=2 MUg/mL were unlikely to be exposed to sufficient gentamicin for effective killing. Approximately 90% of isolates from ambulatory practice and 36% of hospital isolates had MICs at or below breakpoints for susceptibility with most of the remainder unlikely to be responsive, even to higher IV doses. CONCLUSIONS AND CLINICAL IMPORTANCE: Gentamicin at a dosage of 6.6 mg/kg IV is likely to be effective against the majority of infections encountered in ambulatory practice, but less effective in an equine hospital. Because there was a dichotomy of most bacteria as being clearly susceptible or clearly resistant to gentamicin, it appears unlikely that higher doses would have been more efficacious, especially in the hospitalized population in our study. PMID- 29575240 TI - Role of p38 MAPK in disease relapse and therapeutic resistance by maintenance of cancer stem cells in head and neck squamous cell carcinoma. AB - AIM: This study aimed to investigate the role of p38 MAPK in maintenance of cancer stem cell (CSC) phenotype, therapy resistance, and DNA damage repair and response in head and neck squamous cell carcinoma (HNSCC). METHODS: In this study, 104 HNSCC patients were included. Western blot, immunohistochemistry, and qPCR analysis were performed to investigate the expression level of p-p38 and CSC markers in cut margin and tumor area of HNSCC patients. The expression level of p p38 and CSC markers was also evaluated in HNSCC cells with or without p38 inhibitor. Chemoresistance, wound healing capacity, and multicellular tumor spheroids (MCTS) formation capacity were evaluated in HNSCC-derived cell lines with or without p38 inhibitor. In addition, DNA damage response and repair capacities were also evaluated in HNSCC cells after p38 inhibition using alkaline comet assay and gamma-H2 AX immunostaining. RESULT: We observed that recurrence could be associated with upregulated status of p-p38 and p38alpha gene in cut margin area of HNSCC patients as compared to tumor region. p38-inhibited cells showed significantly reduced expression of CSC markers, chemosensitivity toward cisplatin, reduced migration potential, and sphere-forming ability along with increased apoptotic population after treatment with increasing concentration of cisplatin. p38-inhibited cells also exhibited significantly increased comet olive tail moment and accumulation of gamma-H2 AX, demonstrating increased DNA damage. CONCLUSION: This study demonstrated that p38 MAPK activation may play a role in therapeutic resistance and disease relapse in HNSCC by maintenance of CSCs phenotype. PMID- 29575241 TI - Randomized controlled feasibility trial of supported self-management in adults with Type 2 diabetes mellitus and an intellectual disability: OK Diabetes. AB - AIMS: To undertake a feasibility randomized controlled trial of supported self management vs treatment as usual in a population of adults with obesity, Type 2 diabetes and an intellectual disability. METHODS: We conducted an individually randomized feasibility trial. Participants were adults aged >18 years with a mild or moderate intellectual disability, living in the community with Type 2 diabetes, on any therapy other than insulin. Participants had mental capacity to consent to research and the intervention. Inclusion criteria included HbA1c > 48 mmol/mol (6.5%), BMI >25 kg/m2 , or self-reported physical activity below national guideline levels. The experimental intervention was standardized supported self-management delivered by diabetes specialist nurses plus treatment as usual, compared with treatment as usual alone. Feasibility outcomes included: recruitment and retention; intervention acceptability and feasibility; data collection and completeness for physiological state and values for candidate primary outcomes (HbA1c and BMI). RESULTS: A total of 82 participants (89% of those contacted and eligible) were randomized. All supported self-management sessions were completed by 35/41 participants (85%); only four completed no sessions. Data on the follow-up candidate primary outcomes HbA1c and BMI were obtained for 75/82 (91%) and 77/82 participants (94%), respectively. The mean baseline HbA1c was 56+/-16.5 mmol/mol (7.3+/-1.5%) and the mean BMI was 34+/-7.6 kg/m2 . CONCLUSIONS: Adherence to supported self-management and willingness to have blood taken for outcome measurement was good. A definitive randomized controlled trial is feasible in this population.

PMID- 29575242 TI - Methodology for computing the burden of disease of adverse events following immunization. AB - PURPOSE: Composite disease burden measures such as disability-adjusted life-years (DALY) have been widely used to quantify the population-level health impact of disease or injury, but application has been limited for the estimation of the burden of adverse events following immunization. Our objective was to assess the feasibility of adapting the DALY approach for estimating adverse event burden. METHODS: We developed a practical methodological framework, explicitly describing all steps involved: acquisition of relative or absolute risks and background event incidence rates, selection of disability weights and durations, and computation of the years lived with disability (YLD) measure, with appropriate estimation of uncertainty. We present a worked example, in which YLD is computed for 3 recognized adverse reactions following 3 childhood vaccination types, based on background incidence rates and relative/absolute risks retrieved from the literature. RESULTS: YLD provided extra insight into the health impact of an adverse event over presentation of incidence rates only, as severity and duration are additionally incorporated. As well as providing guidance for the deployment of DALY methodology in the context of adverse events associated with vaccination, we also identified where data limitations potentially occur. CONCLUSIONS: Burden of disease methodology can be applied to estimate the health burden of adverse events following vaccination in a systematic way. As with all burden of disease studies, interpretation of the estimates must consider the quality and accuracy of the data sources contributing to the DALY computation.

This complexity arises from the rate at which new studies are published and from the terminology that varies widely from study-to-study and even more so from discipline-to-discipline. One way to investigate and manage this problem is to build a "semantic space" that maps the different vocabulary used in functional neuroimaging literature. Such a semantic space will also help identify the primary research domains of neuroimaging and their most commonly reported brain regions. In this work, we analyzed the multivariate semantic structure of abstracts in Neurosynth and found that there are six primary domains of the functional neuroimaging literature, each with their own preferred reported brain regions. Our analyses also highlight possible semantic sources of reported brain regions within and across domains because some research topics (e.g., memory disorders, substance use disorder) use heterogeneous terminology. Furthermore, we highlight the growth and decline of the primary domains over time. Finally, we note that our techniques and results form the basis of a "recommendation engine" that could help readers better navigate the neuroimaging literature.

AB - BACKGROUND: Intrauterine growth restriction (IUGR) has been shown to be associated with increased risk of renal disease or hypertension in later life. Glomerular dysfunction, however, has mainly been reported, and limited information is available to link IUGR with renal tubular damage. The aim of this study was therefore to investigate urinary markers of tubular damage in a rat model of IUGR induced by bilateral uterine artery ligation. METHODS: Pregnant Sprague-Dawley rats underwent bilateral uterine artery ligation, while the control group underwent sham surgery. RESULTS: Birthweight was reduced, and urinary beta2-microglobulin (beta2-MG)-, cystatin C (Cys-C)-, and calbindin-to creatinine ratios were significantly higher at weeks 4 and 8 in the IUGR group compared with the control group. These urinary markers were not significantly different at week 16 between the two groups. Increased excretion of urinary beta2 MG, Cys-C, and calbindin was observed in IUGR rats at >=8 weeks of age. CONCLUSION: Children born with IUGR are at increased risk for renal tubular damage.

AB - To facilitate survival under drug stresses, a small population of Mycobacterium tuberculosis can tolerate bactericidal concentrations of drugs without genetic mutations. These drug-tolerant mycobacteria can be induced by environmental stresses and contribute to recalcitrant infections. However, mechanisms underlying the development of drug-tolerant mycobacteria remain obscure. Herein, we characterized a regulatory pathway which is important for the tolerance to isoniazid (INH) in Mycobacterium smegmatis. We found that the RNA polymerase binding protein RbpA associates with the stress response sigma factor sigmaB , to activate the transcription of ppk1, the gene encoding polyphosphate kinase. Subsequently, intracellular levels of inorganic polyphosphate increase to promote INH-tolerant mycobacteria. Interestingly, sigmaB and ppk1 expression varied proportionately in mycobacterial populations and positively correlated with tolerance to INH in individual mycobacteria. Moreover, sigB and ppk1 transcription are both induced upon nutrient depletion, a condition that stimulates the formation of INH-tolerant mycobacteria. Over-expression of ppk1 in rbpA knockdown or sigB deleted strains successfully restored the number of INH tolerant mycobacteria under both normal growth and nutrient starved conditions. These data suggest that RbpA and sigmaB regulate ppk1 expression to control drug tolerance both during the logarithmic growth phase and under the nutrition starved conditions. PMID- 29575248 TI - A High-yield Fall Risk and Adverse Events Screening Questions From the Stopping Elderly Accidents, Death, and Injuries (STEADI) Guideline for Older Emergency Department Fall Patients. AB - OBJECTIVES: The objectives were to examine whether responses to the Stopping Elderly Accidents, Death, and Injuries (STEADI) questions responses predicted adverse events after an older adult emergency department (ED) fall visits and to identify factors associated with such recurrent fall. METHODS: We conducted a prospective study at two urban, teaching hospitals. We included patients aged >= 65 years who presented to the ED for an accidental fall. Data were gathered for fall-relevant comorbidities, high-risk medications for falls, and the responses to 12 questions from the STEADI guideline recommendation. Our outcomes were the number of 6-month adverse events that were defined as mortality, ED revisit, subsequent hospitalization, recurrent falls, and a composite outcome. RESULTS: There were 548 (86.3%) patients who completed follow-up and 243 (44.3%) patients experienced an adverse event after a fall within 6 months. In multivariate analysis, seven questions from the STEADI guideline predicted various outcomes. The question "Had previous fall" predicted recurrent falls (odds ratio [OR] = 2.45, 95% confidence interval [CI] = 1.52 to 3.97), the question "Feels unsteady when walking sometimes" (OR = 2.34, 95% CI = 1.44 to 3.81), and "Lost some feeling in their feet" predicted recurrent falls. In addition to recurrent falls risk, the supplemental questions "Use or have been advised to use a cane or walker," "Take medication that sometimes makes them feel light-headed or more tired than usual," "Take medication to help sleep or improve mood," and "Have to rush to a toilet" predicted other outcomes. CONCLUSION: A STEADI score of >=4 did not predict adverse outcomes although seven individual questions from the STEADI guidelines were associated with increased adverse outcomes within 6 months. These may be organized into three categories (previous falls, physical activity, and high-risk medications) and may assist emergency physicians to evaluate and refer high-risk fall patients for a comprehensive falls evaluation. PMID- 29575249 TI - Separate neural representations of prediction error valence and surprise: Evidence from an fMRI meta-analysis. AB - Learning occurs when an outcome differs from expectations, generating a reward prediction error signal (RPE). The RPE signal has been hypothesized to simultaneously embody the valence of an outcome (better or worse than expected) and its surprise (how far from expectations). Nonetheless, growing evidence suggests that separate representations of the two RPE components exist in the human brain. Meta-analyses provide an opportunity to test this hypothesis and directly probe the extent to which the valence and surprise of the error signal are encoded in separate or overlapping networks. We carried out several meta analyses on a large set of fMRI studies investigating the neural basis of RPE, locked at decision outcome. We identified two valence learning systems by pooling studies searching for differential neural activity in response to categorical positive-versus-negative outcomes. The first valence network (negative > positive) involved areas regulating alertness and switching behaviours such as the midcingulate cortex, the thalamus and the dorsolateral prefrontal cortex whereas the second valence network (positive > negative) encompassed regions of the human reward circuitry such as the ventral striatum and the ventromedial prefrontal cortex. We also found evidence of a largely distinct surprise-encoding network including the anterior cingulate cortex, anterior insula and dorsal striatum. Together with recent animal and electrophysiological evidence this meta analysis points to a sequential and distributed encoding of different components of the RPE signal, with potentially distinct functional roles.

AB - Light-emitting diodes utilizing perovskite nanocrystals have generated strong interest in the past several years, with green and red devices showing high efficiencies. Blue devices, however, have lagged significantly behind. Here, it is shown that the device architecture plays a key role in this lag and that NiOx , a transport layer in one of the highest efficiency devices to date, causes a significant reduction in perovskite luminescence lifetime. An alternate transport layer structure which maintains robust nanocrystal emission is proposed. Devices with this architecture show external quantum efficiencies of 0.50% at 469 nm, seven times higher than state-of-the-art devices at that wavelength. Finally, it is demonstrated that this architecture enables efficient devices across the entire blue-green portion of the spectrum. The improvements demonstrated here open the door to efficient blue perovskite light-emitting diodes. PMID- 29575251 TI - Treatment for moderate to severe atopic dermatitis in alpine and moderate maritime climates differentially affects helper T cells and memory B cells in children. AB - BACKGROUND: Treatment of atopic dermatitis (AD) is focused on topical anti inflammatory therapy, epidermal barrier repair and trigger avoidance. Multidisciplinary treatment in both moderate maritime and alpine climates can successfully reduce disease activity in children with AD. However, it remains unclear whether abnormalities in B cell and T cell memory normalize and whether this differs between treatment strategies. OBJECTIVE: To determine whether successful treatment in maritime and alpine climates normalizes B- and T lymphocytes in children with moderate to severe AD. METHODS: The study was performed in the context of a trial (DAVOS trial, registered at Current Controlled Trials ISCRTN88136485) in which eighty-eight children with moderate to severe AD were randomized to 6 weeks of treatment in moderate maritime climate (outpatient setting) or in the alpine climate (inpatient setting). Before and directly after treatment, disease activity was determined with SA-EASI and serum TARC, and T cell and B cell subsets were quantified in blood. RESULTS: Both treatment protocols achieved a significant decrease in disease activity, which was accompanied by a reduction in circulating memory Treg, transitional B cell and plasmablast numbers. Alpine climate treatment had a significantly greater effect on disease activity and was accompanied by a reduction in blood eosinophils and increases in memory B cells, CD8+ TemRO, CD4+ Tcm and CCR7+ Th2 subsets. CONCLUSIONS AND CLINICAL RELEVANCE: Clinically successful treatment of AD induces changes in blood B- and T cell subsets reflecting reduced chronic inflammation. In addition, multidisciplinary inpatient treatment in the alpine climate specifically affects memory B cells, CD8+ T cells and Th2 cells. These cell types could represent good markers for treatment efficacy. PMID- 29575252 TI - Decomposition of cyanobacterial light harvesting complexes: NblA-dependent role of the bilin lyase homolog NblB. AB - Phycobilisomes, the macromolecular light harvesting complexes of cyanobacteria are degraded under nutrient-limiting conditions. This crucial response is required to adjust light excitation to the metabolic status and avoid damage by excess excitation. Phycobilisomes are comprised of phycobiliproteins, apo proteins that covalently bind bilin chromophores. In the cyanobacterium Synechococcus elongatus, the phycobiliproteins allophycocyanin and phycocyanin comprise the core and the rods of the phycobilisome, respectively. Previously, NblB was identified as an essential component required for phycocyanin degradation under nutrient starvation. This protein is homologous to bilin lyases, enzymes that catalyze the covalent attachment of bilins to apo-proteins. However, the nblB-inactivated strain is not impaired in phycobiliprotein synthesis, but rather is characterized by aberrant phycocyanin degradation. Here, using a phycocyanin-deficient strain, we demonstrate that NblB is required for degradation of the core pigment, allophycocyanin. Furthermore, we show that the protein NblB is expressed under nutrient sufficient conditions, but during nitrogen starvation its level decreases about two-fold. This finding is in contrast to an additional component essential for degradation, NblA, the expression of which is highly induced under starvation. We further identified NblB residues required for phycocyanin degradation in vivo. Finally, we demonstrate phycocyanin degradation in a cell-free system, thereby providing support for the suggestion that NblB directly mediates pigment degradation by chromophore detachment. The dependence of NblB function on NblA revealed using this system, together with the results indicating presence of NblB under nutrient sufficient conditions, suggests a rapid mechanism for induction of pigment degradation, which requires only the expression of NblA. PMID- 29575253 TI - Conservation of a domestic metapopulation structured into related and partly admixed strains. AB - Preservation of genetic diversity is one of the most pressing challenges in the planetary boundaries concept. Within this context, we focused on genetic diversity in a native, unselected and highly admixed domesticated metapopulation. A set of 1,828 individuals from 60 different cattle breeds was analysed using a medium density SNP chip. Among these breeds, 14 Busa strains formed a metapopulation represented by 350 individuals, while the remaining 46 breeds represented the global cattle population. Genetic analyses showed that the scarcely selected and less differentiated Busa metapopulation contributed a substantial proportion (52.6%) of the neutral allelic diversity to this global taurine population. Consequently, there is an urgent need for synchronized maintenance of this highly fragmented domestic metapopulation, which is distributed over several countries without sophisticated infrastructure and highly endangered by continuous replacement crossing as part of the global genetic homogenization process. This study collected and evaluated samples, data and genomewide information and developed genome-assisted cross-border conservation concepts. To detect and maintain genetic integrity of the metapopulation strains, we designed and applied a composite test that combines six metrics based on additive genetic relationships, a nearest neighbour graph and the distribution of semiprivate alleles. Each metric provides distinct information components about past admixture events and offers an objective and powerful tool for the detection of admixed outliers. The here developed conservation methods and presented experiences could easily be adapted to comparable conservation programmes of domesticated or other metapopulations bred and kept in captivity or under some other sort of human control. PMID- 29575254 TI - Phase II study of adjuvant chemotherapy with paclitaxel and nedaplatin for uterine cervical cancer with lymph node metastasis. AB - The purpose of this phase II trial was to assess the efficacy and toxicity of paclitaxel and nedaplatin (TN) as the initial postoperative adjuvant chemotherapy for uterine cervical cancer with lymph node metastases (LNM). Patients with FIGO stage IB1-IIA2 squamous cell carcinoma of the uterine cervix were enrolled. Histological confirmation of LNM was mandatory. Intravenous paclitaxel at 175 mg/m2 and nedaplatin at 80 mg/m2 were administered every 28-day cycle, of which there were 5 cycles after radical hysterectomy. Sixty-two patients were enrolled in the study from November 2011 to July 2015. Their median age was 48.5 years (range 28-64). The median tumor diameter was 37 mm (5-64). Overall, 30 patients (48.4%) had 1 metastatic lymph node, 11 (17.7%) had 2, 3 (4.8%) had 3, 5 (8.1%) had 4, and 13 (21.0%) had 5 or more. With a median follow-up of 45.7 months (range 23.4-69.5), the 2-year relapse-free survival and 2-year overall survival rates were 79.0% (90% CI, 69.0%-86.2%) and 93.5% (95% CI, 83.7%-97.5%), respectively. Almost all adverse events were relatively mild. Grade 3-4 adverse events (NCI-CTC ver. 4.0) that occurred in 5% or more of patients were neutropenia (60.7%) and infection (6.6%). The proportion of patients who completed 5 cycles of treatment was 90.3%. Postoperative adjuvant chemotherapy with TN for cervical cancer with LNM was demonstrated to be an effective and feasible treatment. A phase III trial is warranted to compare this with concurrent chemoradiotherapy. PMID- 29575255 TI - Multidimensional Synergistic Nanoarchitecture Exhibiting Highly Stable and Ultrafast Sodium-Ion Storage. AB - Conversion-type anodes with multielectron reactions are beneficial for achieving a high capacity in sodium-ion batteries. Enhancing the electron/ion conductivity and structural stability are two key challenges in the development of high performance sodium storage. Herein, a novel multidimensionally assembled nanoarchitecture is presented, which consists of V2 O3 nanoparticles embedded in amorphous carbon nanotubes that are then coassembled within a reduced graphene oxide (rGO) network, this materials is denoted V2 O3 ?C-NTs?rGO. The selective insertion and multiphase conversion mechanism of V2 O3 in sodium-ion storage is systematically demonstrated for the first time. Importantly, the naturally integrated advantages of each subunit synergistically provide a robust structure and rapid electron/ion transport, as confirmed by in situ and ex situ transmission electron microscopy experiments and kinetic analysis. Benefiting from the synergistic effects, the V2 O3 ?C-NTs?rGO anode delivers an ultralong cycle life (72.3% at 5 A g-1 after 15 000 cycles) and an ultrahigh rate capability (165 mAh g-1 at 20 A g-1 , ~30 s per charge/discharge). The synergistic design of the multidimensionally assembled nanoarchitecture produces superior advantages in energy storage.

PMID- 29575257 TI - Variation in proteomics and metabolomics of chicken hepatocytes exposed to medium with or without folic acid. AB - Hepatocytes are suitable models for metabolism study. Combined proteomics and metabolomics approaches should provide a comprehensive understanding for the effect of folic acid on hepatic metabolism in vitro. Primary chicken liver cells were exposed to medium with or without folic acid. The combined analyses uncovered 61 differential proteins and 43 differential metabolites between groups with or without folic acid in culture medium. Further pathway annotations revealed that RNA transport, protein processing, TCA cycle, glycolysis, pyruvate metabolism, and so on were significantly enriched. Meanwhile, lipid metabolism was enhanced in no folic acid group along with higher adipose triglyceride lipase, and 2-hydroxybutyric acid level. Concomitantly, amino acid, and carbohydrates metabolism were disturbed. Some amino acids level were changed as well as sugar-acids and sugar-alcohols. In addition, antioxidant function was altered resulting from perturbation of glutathione metabolism, glutamate, and cysteine metabolism. In conclusion, our results indicated that folic acid might affect antioxidant function and metabolism of lipid, amino acid, and carbohydrates in primary chicken hepatocytes via integrating proteomics, and metabolomics analyses method. These results may provide an insight into the effect of folic acid on hepatic metabolism in future research direction. PMID- 29575258 TI - Excitonic Properties of Chemically Synthesized 2D Organic-Inorganic Hybrid Perovskite Nanosheets. AB - 2D organic-inorganic hybrid perovskites (OIHPs) represent a unique class of materials with a natural quantum-well structure and quasi-2D electronic properties. Here, a versatile direct solution-based synthesis of mono- and few layer OIHP nanosheets and a systematic study of their electronic structure as a function of the number of monolayers by photoluminescence and absorption spectroscopy are reported. The monolayers of various OIHPs are found to exhibit high electronic quality as evidenced by high quantum yield and negligible Stokes shift. It is shown that the ground exciton peak blueshifts by ~40 meV when the layer thickness reduces from bulk to monolayer. It is also shown that the exciton binding energy remains effectively unchanged for (C6 H5 (CH2 )2 NH3 )2 PbI4 with the number of layers. Similar trends are observed for (C4 H9 NH3 )2 PbI4 in contrast to the previous report. Further, the photoluminescence lifetime is found to decrease with the number of monolayers, indicating the dominant role of surface trap states in nonradiative recombination of the electron-hole pairs. PMID- 29575259 TI - Crocin improves renal function by declining Nox-4, IL-18, and p53 expression levels in an experimental model of diabetic nephropathy. AB - Oxidative damage, inflammation and apoptosis play significant roles in diabetic nephropathy. Previous studies demonstrated anti-inflammatory and anti-oxidative effects of crocin, but there is no evidence about its effects on IL-18, NOX-4, and p53 expression in diabetic kidneys. The aim of this study was to evaluate possible effects of crocin on improving main mechanisms underlying diabetic nephropathy. Male Wistar rats were randomly divided into four separate groups as normal (C), normal treated (CC), diabetic (D), and diabetic treated (DC) (n = 6). Diabetes was induced by a single dose of streptozotocin (40 mg/kg/intravenous). Treated groups received crocin (40 mg/kg, intraperitoneal) for 8 weeks. At the end of the 8th week of the study, all rats were sacrificed and urine, blood and tissue were collected. Levels of urea, uric acid, creatinine and glucose were determined collected sera, and proteinuria was measured in urine samples. Moreover, the contents of malondialdehyde (MDA), nitrate, and glutathione (GLT) as well as catalase (CAT) and superoxide dismutase (SOD) enzymes activities were measured. The expression of NOX-4, IL-18, and p53 at both mRNA and protein levels were also assessed. Hyperglycemia significantly increased proteinuria in diabetic rats (D). Also, depressed antioxidant defense system potency, but increased NOX-4 expression and free radicals production resulting in oxidative stress, were observed. Moreover, expressions of IL-18 (as a marker of inflammation) and p53 (as a marker of apoptosis) were increased. These outcomes were accompanied by enhanced histological damages and renal failure but, treatment with crocin improved these deteriorations, and ameliorated renal function. It potentiated renal cells antioxidant defense system and declined inflammation. Also, crocin lowered apoptosis and improved histological damages in renal cells. Oxidative stress, inflammation and apoptosis are considered three main mechanisms underlying diabetic nephropathy. Treatment with crocin prevented these deleterious effects and improved renal function under diabetic conditions. PMID- 29575260 TI - The joint evolution of the Myxozoa and their alternate hosts: A cnidarian recipe for success and vast biodiversity. AB - The relationships between parasites and their hosts are intimate, dynamic and complex; the evolution of one is inevitably linked to the other. Despite multiple origins of parasitism in the Cnidaria, only parasites belonging to the Myxozoa are characterized by a complex life cycle, alternating between fish and invertebrate hosts, as well as by high species diversity. This inspired us to examine the history of adaptive radiations in myxozoans and their hosts by determining the degree of congruence between their phylogenies and by timing the emergence of myxozoan lineages in relation to their hosts. Recent genomic analyses suggested a common origin of Polypodium hydriforme, a cnidarian parasite of acipenseriform fishes, and the Myxozoa, and proposed fish as original hosts for both sister lineages. We demonstrate that the Myxozoa emerged long before fish populated Earth and that phylogenetic congruence with their invertebrate hosts is evident down to the most basal branches of the tree, indicating bryozoans and annelids as original hosts and challenging previous evolutionary hypotheses. We provide evidence that, following invertebrate invasion, fish hosts were acquired multiple times, leading to parallel cospeciation patterns in all major phylogenetic lineages. We identify the acquisition of vertebrate hosts that facilitate alternative transmission and dispersion strategies as reason for the distinct success of the Myxozoa, and identify massive host specification-linked parasite diversification events. The results of this study transform our understanding of the origins and evolution of parasitism in the most basal metazoan parasites known.

AB - There is a burgeoning literature regarding using Internet-based data in employment, university admissions, and healthcare settings, but such pertaining to forensic mental health assessment (FMHA) contexts is only beginning to develop and professional ethics codes have yet to address these issues in depth. We present the first empirical investigation of mental health and related professionals' (n = 139) attitudes and practices regarding using Internet data in forensic and therapeutic contexts. Respondents reported their experiences and levels of agreement with items measuring beliefs and attitudes toward using Internet-based data in various professional situations (e.g., 23% have searched the Internet for information about a therapy client, 39% for a forensic examinee, and only 26% opposed the practice for forensic evaluators). They also reported high levels of collective agreement, including feeling that there is a lack of guidance available from professional resources regarding Internet-related issues. Implications for forensic practice and research are presented. PMID- 29575262 TI - Structural basis for tumor necrosis factor blockade with the therapeutic antibody golimumab. AB - Tumor necrosis factor alpha (TNFalpha) is a proinflammatory cytokine, and elevated levels of TNFalpha in serum are associated with various autoimmune diseases, including rheumatoid arthritis (RA), ankylosing spondylitis (AS), Crohn's disease (CD), psoriasis, and systemic lupus erythaematosus. TNFalpha performs its pleiotropic functions by binding to two structurally distinct transmembrane receptors, TNF receptor (TNFR) 1 and TNFR2. Antibody-based therapeutic strategies that block excessive TNFalpha signaling have been shown to be effective in suppressing such harmful inflammatory conditions. Golimumab (Simponi(r)) is an FDA-approved fully human monoclonal antibody targeting TNFalpha that has been widely used for the treatment of RA, AS, and CD. However, the structural basis underlying the inhibitory action of golimumab remains unclear. Here, we report the crystal structure of the Fv fragment of golimumab in complex with TNFalpha at a resolution of 2.73 A. The resolved structure reveals that golimumab binds to a distinct epitope on TNFalpha that does not overlap with the binding residues of TNFR2. Golimumab exerts its inhibitory effect by preventing binding of TNFR1 and TNFR2 to TNFalpha by steric hindrance. Golimumab does not induce conformational changes in TNFalpha that could affect receptor binding. This mode of action is specific to golimumab among the four anti TNFalpha therapeutic antibodies currently approved for clinical use. PMID- 29575263 TI - Mohs micrographic surgery for cutaneous malignancies: A focus review of its indications in pediatric age groups. AB - Mohs micrographic surgery (MMS) is a highly specialized technique that has been successful in the treatment of a variety of skin tumors. The technique can be performed as an outpatient procedure and encompasses surgical excision and intraoperative assessment of tumor margins in one setting by the same physician. The process ensures precise margin control with maximal preservation of healthy tissues. Mohs micrographic surgery has been practiced worldwide, including in the United States, Europe (United Kingdom, Germany, Spain, Netherlands, Switzerland), and Australia. Although it is commonly performed in adults with greater success, it has been discussed less frequently in children. In this article, we describe several cutaneous tumors in children and the role of Mohs micrographic surgery in their management. A PubMed search was conducted to review the most common cutaneous tumors in children treated using Mohs micrographic surgery. In this review, we discuss indications for Mohs micrographic surgery and pertinent studies examining success rates in children. Mohs micrographic surgery has been used to treat several tumors in children and offers the advantage of high cure rates and tissue conservation. This report emphasizes the benefits of Mohs micrographic surgery in children and highlights several cutaneous tumors for which it has been used to treat successfully. PMID- 29575264 TI - Attachment and adaptation to breast cancer: The mediating role of avoidant emotion processes. AB - Attachment insecurity is associated with difficulties in adapting to cancer. Accumulating evidence points to the influence of avoidant emotion processes in this association. This study explored this pathway by examining the association between attachment insecurity and quality of life in women with breast cancer, and by exploring the mediating role of two avoidant emotion processes in this association. Women with breast cancer (N = 155) completed measures of attachment, emotional suppression, emotional awareness and quality of life. Avoidance of attachment was positively associated with emotional suppression (beta = .29, p < .01) and lack of emotional awareness (beta = .27, p < .01), and negatively associated with quality of life (beta = -.22, p < .05). Lack of emotional awareness partially mediated the relationship between attachment avoidance and quality of life (indirect effect beta = -.12, p = .008). Attachment anxiety was not associated with any variable. Attachment avoidance may hinder the process of adaptation to breast cancer and difficulties in identifying and describing emotions may be partly responsible for this influence. Access to and ability to benefit from social and medical supports is likely to depend on being able to engage with others and recognise and process emotions effectively. Research and clinical implications are discussed.

AB - This study was to test our hypothesis that flexor tendon reconstruction with an allograft revitalized with bone marrow stromal cells (BMSCs) and synovialized with carbodiimide derivatized autologous synovial fluid (cd-SYN) would result in better digit functional restoration than the conventional allograft tendon. A total of 32 flexor digital profundus tendons from the second and fifth digit of 16 dogs were created a repair failure model first. Then, failed-repaired tendons were reconstructed with either a revitalized-synovialized allograft tendon or a clinical standard autograft tendon (control group). The allograft tendon was seeded with autologous BMSCs in multiple slits and the graft surface was coated with cd-SYN. A 6 weeks after tendon reconstruction, the digits were harvested and evaluated for digit function, adhesion status, tendon gliding resistance, attachment strength, cell viability, and histologic factors. The allograft group had significantly improved digit function compared with the control group through decreased work of flexion, increased digit range of motion under 2-Newton force, and less adhesion score (p < .05). However, the distal attachment-site strength and stiffness in the allograft tendon were significantly weaker than the autografts (p < .05). No significant difference was found for gliding resistance. Histologically, allograft tendons coated with allograft had smoother surfaces and showed tendon-to-bone and tendon-to-tendon incorporation. Viable BMSCs were found in the tendon slits 6 weeks after the graft. In conclusion, cellular lubricant based modification of allograft tendons improved digit function and reduced the adhesions compared with autograft for flexor tendon reconstruction. However, improvement of graft-to-host tendon healing is still challenging. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res.

AB - Colorectal cancer (CRC) is one of the most prevalent cancers worldwide with rising mortality rates predicted in the coming decades. In light of this, there is a continued need for improvement in our understanding of CRC biology and the development of novel treatment options. Tumor-derived extracellular vesicles (tEVs) have emerged as both novel cancer biomarkers and functional mediators of carcinogenesis. tEVs are released by tumor cells in abundance and play an important role in mediating tumor cell-immune cell interactions in the tumor microenvironment. Furthermore, tEVs are released into the circulation in humans where they could also interact with circulating immune cells. This review aims to describe CRC-specific tEVs and what is currently known about their role in immunomodulation. In particular, we discuss the ability of CRC-derived tEVs to affect monocyte differentiation into macrophages and dendritic cells, and their effects on T-cell viability and activity. Finally, the potential for tEVs in the development of immunotherapies will be discussed.

AB - The reversible electrostatic adsorption of the cationic dye methylene blue (MB) as a model compound to polydehydroalanine (PDha)-coated magnetic multicore nanoparticles (MCNP) is presented. The pH responsiveness of the zwitterionic coating material enables reversible switching of the net surface charge of the PDha@MCNP hybrid particles by changes in pH and thus allows reversible adsorption of MB at neutral pH and desorption at low pH values. The resulting hybrid materials can be very interesting systems in the context of water purification, and the reversible adsorption is studied using UV-vis spectroscopy under varying surrounding conditions. The particles are characterized using dynamic light scattering, zeta potential measurements, transmission electron microscopy, and thermogravimetric analysis. PMID- 29575271 TI - OCT image atlas of healthy skin on sun-exposed areas. AB - BACKGROUND: Skin cancer represents the most prevalent type of cancer in the United States. Excision of these lesions can leave significant scarring, and a delay in the diagnosis of malignant melanoma could result in metastasis or death. Therefore, developing technology and criteria to accurately diagnose these cancers is of particular importance to the medical community. While biopsy can lead to scarring and infections, dermoscopy and confocal microscopy offer noninvasive imaging methods but are also limited in their ability to determine tumor depth and margins. Optical coherence tomography (OCT) is a promising imaging method that uses near-infrared light backscattering to image structures underneath the surface of the skin. The purpose of this study is to provide examples of variations across different skin locations and to identify common themes that occur with aging and sun exposure, most notably thinning of the epidermis and loss of a distinct dermal-epidermal junction. METHODS: Optical coherence tomography images were taken using the VivoSight swept-source OCT. Images were taken from a 23-year-old man (Subject 1) and an 89-year-old man (Subject 2), both with Fitzpatrick Skin Type I, who did not have any prior skin conditions. We investigated the regions of the body that represent sun-exposed areas. RESULTS: Results including OCT images taken from 19 predominately sun exposed areas are shown in Figure 2-Figure 20. CONCLUSION: The 2 sets of images demonstrate the variety that exists within OCT imaging of healthy skin, and thus, a comprehensive understanding of the variation in normal skin imaging using OCT is critical to be able to distinguish and diagnose skin cancers when present.

AB - This article introduces an analysis-aware microscopy video compression method designed for microscopy videos that are consumed by analysis algorithms rather than by the human visual system. We define the quality of a microscopy video based on the level of preservation of analysis results. We evaluated our method with a bead tracking analysis program. For the same error level in the analysis result, our method can achieve 1,000* compression on certain test microscopy videos. Compared with a previous technique that yields exactly the exact same results by analysis algorithms, our method gives more flexibility for a user to control the quality. A modification to the new method also provides faster compression speed.

AB - Electrochemical conversion of CO2 to value-added chemicals using renewable electricity provides a promising way to mitigate both global warming and the energy crisis. Here, a facile ion-adsorption strategy is reported to construct highly active graphene-based catalysts for CO2 reduction to CO. The isolated transition metal cyclam-like moieties formed upon ion adsorption are found to contribute to the observed improvements. Free from the conventional harsh pyrolysis and acid-leaching procedures, this solution-chemistry strategy is easy to scale up and of general applicability, thus paving a rational avenue for the design of high-efficiency catalysts for CO2 reduction and beyond.

AB - BACKGROUND: Cancer prevention is essential after transplantation (Tx). The use of HE4 and Risk of Ovarian Malignancy Algorithm (ROMA) is recommended as a tool for selective ovarian cancer screening; however, creatinine is a known confounder. This study assessed the reliability of HE4, CA125, and ROMA after Tx. METHODS: We matched a total of 202 women without gynecological malignancies and 236 men by age and serum creatinine. Each pair consisted of a patient after Tx (kidney, liver, heart, and pancreas) and a diseased but non-Tx consecutive patient. Serum HE4, CA125 (Roche Cobas 6000), and creatinine (enzymatic, Abbott Architect) were measured in all patients. RESULTS: Creatinine correlated with HE4 (women: r = .864, P < .0001; men: r = .848, P < .0001). Age correlated slightly with HE4 in women (r = .250, P < .005) and men (r = .240, P < .0005). HE4 in women after Tx (median of 84.8 pmol/L) was significantly higher than non-Tx women (53.7 pmol/L, P < .0001) in the reference range of serum creatinine. Neither HE4 nor CA125 correlated with tacrolimus concentration, but anemia, hyperparathyroidism, kidney, liver, and lung diseases were possible confounders for HE4 after transplantation (P < .05). CONCLUSION: Human epididymis protein 4 (HE4) was significantly increased in women after solid organ transplantation compared to levels without transplants matched by age and serum creatinine. HE4 results may be misleading in these patients. PMID- 29575277 TI - Association study of functional polymorphisms of dopaminergic pathway in epilepsy related factors of temporal lobe epilepsy in Brazilian population. AB - BACKGROUND AND PURPOSE: There are few data about the role of neurotransmission modulated by dopamine in epilepsy, especially temporal lobe epilepsy (TLE). This is the first study that aimed to analyze the dopaminergic polymorphisms in an etiologically homogeneous group of patients with TLE with hippocampal sclerosis. Selected polymorphisms were: (i) the most expressed D2-like receptors in the limbic system (DRD2/ANKK1 TAQ-1A, D4_VNTR and D4_rs1800955); (ii) the dopamine transporter (DAT) 3'-untranslated region and intron 8; and (iii) two degrading enzymes regulating the synaptic activity, i.e. the main metabolizer of dopamine, catechol-O-methyltransferase, and monoamine oxidase A. METHODS: We assessed 119 patients with unequivocal TLE with hippocampal sclerosis and 112 healthy volunteers. Individuals were genotyped for the polymorphisms of the gene encoding dopaminergic pathway transporter DAT haplotype, dopaminergic receptors, catechol O-methyltransferase and monoamine oxidase A. We also evaluated epilepsy-related factors (e.g. seizure frequency, age of onset, duration and status epilepticus). RESULTS: There was no difference between the groups for the studied polymorphisms. The polymorphism DRD4_VNTR was associated with family history of epilepsy (P = 0.003), DRD2_rs1800497 was related to status epilepticus (P = 0.022), and intron 8 VNTR DAT was related to higher seizure frequency (P = 0.019) and family history of epilepsy (P = 0.011). CONCLUSIONS: Our findings demonstrated that polymorphisms of the dopaminergic pathway are associated with significant clinical features of this form of epilepsy, such as seizure frequency, family history of epilepsy and status epilepticus.

The choice of treatment depends on the size of the lesion and on the underlying disease. We present a complex case of severe tracheal injury treated with success with tracheal stent positioning. PMID- 29575279 TI - Enantioselective Catalyst Systems from Copper(II) Triflate and BINOL-Silanediol. AB - Silanediol and copper catalysis are merged, for the first time, to create an enhanced Lewis acid catalyst system for enantioselective heterocycle functionalization. The promise of this silanediol and copper catalyst combination is demonstrated in the enantioselective addition of indoles to alkylidene malonates to give rise to the desirable adducts in excellent yield and high enantiomeric excess. From these studies, 1,1'-bi-2-naphthol (BINOL)-based silanediols emerge as one-of-a-kind cocatalysts. Their potential role in the reaction pathway is also discussed. PMID- 29575280 TI - Renal regeneration after acute kidney injury. AB - Acute kidney injury is common and associated with negative renal and patient outcomes. The human kidney has a real but limited regeneration capacity. Understanding renal regeneration may allow us to manipulate this process and thus develop therapeutic weapons to improve patients' outcome. In the first part of this paper we discuss the clinical factors associated with renal recovery: baseline patient particularities, acute kidney injury characteristics and the medical approach taken in the short and long-term. In the second part, the cellular and molecular mechanisms underlying renal regeneration are explored. The immune system seems to have an important role, first promoting inflammation and then tissue healing. Other players, such as cellular senescence, mitochondrial dysfunction, renal haemodynamics and metabolic reprogramming also have a role in renal regeneration. We aim to develop a short review of renal regeneration, offering a holistic view of this process. PMID- 29575281 TI - Enantioselective Synthesis of 5,5-Disubstituted Hydantoins by Bronsted Base/H Bond Catalyst Assisted Michael Reactions of a Design Template. AB - A new method for the enantioselective synthesis of 5,5-disubstituted (quaternary) hydantoins was developed on the basis of an organocatalytic Michael reaction approach involving the use of 2-benzylthio-3,5-dihydroimidazol-4-ones as key hydantoin surrogates. The method is general with respect to the substitution pattern at the hydantoin N1 (alkyl, aryl, acyl), N3 (aryl), and C5 (linear/branched alkyl, aryl) positions and affords essentially single diastereomeric products with enantioselectivities higher than 95 % ee in most cases. Among the bifunctional Bronsted base/H-bond catalysts examined, a known squaramide-tertiary amine catalyst and a newly prepared squaramide-tertiary amine catalyst provide the highest selectivity so far with either nitroolefins or vinyl ketones as the acceptor components. Kinetic measurements support a first-order rate dependence on both reaction partners, the donor template and the Michael acceptor, whereas competitive 1 H NMR spectroscopy experiments reveal the high ability of the template for catalyst binding. PMID- 29575282 TI - Genetic signatures through space, time and multiple disturbances in a ubiquitous brooding coral. AB - The predominance of self-recruitment in many reef-building corals has fundamental and complex consequences for their genetic diversity, population persistence and responses to climate change. Knowledge of genetic structure over local scales needs to be placed within a broad spatial context, and also integrated with genetic monitoring through time to disentangle these consequences. Here, we examined patterns of genetic diversity over multiple spatio-temporal scales across tropical Australia in the ubiquitous brooding coral, Seriatopora hystrix. We also analysed complimentary environmental and demographic data to elucidate the seascape drivers of these patterns. Large genetic differences were detected between the east vs. west coasts of Australia. In northwest Australia, geographic differentiation dominated genetic structure over multiple scales. However, three sympatric lineages were detected at the largest offshore reef system (Scott Reef). Similar to the differences observed among putative species in eastern Australia, these lineages were associated with different levels of wave exposure. Local genetic structure within the Scott Reef system was relatively stable over 10 years, but temporal differences were observed that reflected small but important genetic changes over a few generations during recovery after severe bleaching. These results highlight the importance of self-recruitment together with occasional longer distance connectivity for the persistence of a metapopulation across spatially and temporally variable environments. Our multidimensional research provides a foundation for further long-term genetic monitoring to inform conservation strategies and highlights that sampling scales, ecological effects and cryptic diversity are important considerations to develop realistic understanding of the evolutionary resilience of corals. PMID- 29575283 TI - Polyacrylonitrile-Derived Sponge-Like Micro/Macroporous Carbon for Selective CO2 Separation. AB - CO2 capture under a dynamical flow situation requires adsorbents possessing balanced proportion of macropores as diffusion path and micropores as adsorption reservoir. However, the construction of interconnected micro-/macropores structure coupled with abundant nitrogen species into one carbon skeleton remains a challenge. Here, we report a new approach to prepare sponge-like carbon with a well-developed micro-/macroporous structure and enriched nitrogen species through aqueous phase polymerization of acrylonitrile in the presence of graphene oxide. The tension stress caused by the uniform thermal shrinkage of polyacrylonitrile during the pyrolysis together with the favorable flexibility of graphene oxide sheets are responsible for the formation of the sponge-like morphology. The synergistic effect of micro-/macroporous framework and rich CO2 -philic site enables such carbon to decrease resistance to mass transfer and show high CO2 dynamic selectivity over N2 (454) and CH4 (11), as well as good CO2 capacity at 298 K under low CO2 partial pressure (0.17 bar, a typical CO2 partial pressure in flue gas). The above attributes make this porous carbon a promising candidate for CO2 capture from flue gas, methane sources and other relevant applications. PMID- 29575284 TI - Nitrogen fertilization raises CO2 efflux from inorganic carbon: A global assessment. AB - Nitrogen (N) fertilization is an indispensable agricultural practice worldwide, serving the survival of half of the global population. Nitrogen transformation (e.g., nitrification) in soil as well as plant N uptake releases protons and increases soil acidification. Neutralizing this acidity in carbonate-containing soils (7.49 * 109 ha; ca. 54% of the global land surface area) leads to a CO2 release corresponding to 0.21 kg C per kg of applied N. We here for the first time raise this problem of acidification of carbonate-containing soils and assess the global CO2 release from pedogenic and geogenic carbonates in the upper 1 m soil depth. Based on a global N-fertilization map and the distribution of soils containing CaCO3 , we calculated the CO2 amount released annually from the acidification of such soils to be 7.48 * 1012 g C/year. This level of continuous CO2 release will remain constant at least until soils are fertilized by N. Moreover, we estimated that about 273 * 1012 g CO2 -C are released annually in the same process of CaCO3 neutralization but involving liming of acid soils. These two CO2 sources correspond to 3% of global CO2 emissions by fossil fuel combustion or 30% of CO2 by land-use changes. Importantly, the duration of CO2 release after land-use changes usually lasts only 1-3 decades before a new C equilibrium is reached in soil. In contrast, the CO2 released by CaCO3 acidification cannot reach equilibrium, as long as N fertilizer is applied until it becomes completely neutralized. As the CaCO3 amounts in soils, if present, are nearly unlimited, their complete dissolution and CO2 release will take centuries or even millennia. This emphasizes the necessity of preventing soil acidification in N-fertilized soils as an effective strategy to inhibit millennia of CO2 efflux to the atmosphere. Hence, N fertilization should be strictly calculated based on plant-demand, and overfertilization should be avoided not only because N is a source of local and regional eutrophication, but also because of the continuous CO2 release by global acidification. PMID- 29575285 TI - Diquats with Robust Chirality: Facile Resolution, Synthesis of Chiral Dyes, and Application as Selectors in Chiral Analysis. AB - Diquats with extremely high racemization barriers with DeltaG?theor of 233 kJ mol 1 at 180 degrees C are described. Reported configurational robustness is due to a combination of two structural features: the rigid o-xylylene tether connecting the nitrogen atoms and the presence of two substituents in the bay region of the bipyridinium scaffold. The straightforward synthesis of diquats, plus facile resolution and derivatization make them attractive for chiral application studies. This is demonstrated by: 1) synthesis of the first non-racemic diquat dyes with pronounced chiroptical properties, and 2) capability of diquats to interact stereospecifically with chiral molecules. This suggests potential for diquat derivatives to be used as chiral selectors in separation methods.

AB - Planar xanthomas in children represent rare dermatologic findings associated with abnormalities in lipid metabolism. While planar xanthomas in Alagille's syndrome have been well described in the literature, there have been no cases reported of eruptive xanthomas in pediatric liver transplant patients. Herein we report a case of a 16-month-old boy status post-liver transplantation who presents with planar xanthomas secondary to cholangiopathy. A brief review of xanthomas and the related literature is also provided. PMID- 29575287 TI - The health of working nurses: Hypertension prevalence, awareness, treatment and control by medication. AB - AIMS: To investigate hypertension awareness, prevalence and treatment in nurses. BACKGROUND: Nurses are the largest health workforce group, currently facing an ageing demographic and the risk of chronic disease such as hypertension. Little is known about hypertension in nurses despite the potential impact on work productivity. METHODS: A cross-sectional online survey was distributed to nurses and midwives via the professional association and nursing directors. Questions were taken from published longitudinal health studies for blood pressure, hypertension and key sociodemographic and health factors. RESULTS: The participants' (n = 5,041) mean age was 47.99 (SD 11.46) years. The majority knew their blood pressure, more so if they were female, of higher body mass index and aged 45-64 years, but less so if they were smokers. Hypertension prevalence increased with age, peaking at the oldest ages and the majority were treated (anti-hypertensive medication), less so if aged <55 years. Many nurses treated for hypertension had poor blood pressure control, were most often aged 45-54 years and were smokers. CONCLUSIONS: Hypertension prevalence is less in nurses than in the general population, however, once diagnosed treatment is not optimized. IMPLICATIONS FOR NURSING MANAGEMENT: The potential impact of hypertension on older nurses' work productivity justifies work-based support for risk reduction behaviours.

AB - AIM: Although most veterans have a successful transition to civilian life when they leave the military, some struggle to cope and adjust to the demands and challenges of civilian life. This study explores how a variety of psychosocial factors influence veteran adjustment to civilian life in Scotland, UK, and which of these factors predict a poor adjustment. METHODS: One hundred and fifty-four veterans across Scotland completed a set of questionnaires that measured veteran adjustment difficulty, quality of life, mental health, stigma, self-stigma, attitude towards help-seeking, likelihood of help-seeking, experiential avoidance, reappraisal and suppression. RESULTS: Veteran adjustment difficulty and quality of life were significantly correlated to a number of psychosocial factors. Mental health, experiential avoidance and cognitive reappraisal were found to be predictors of veteran adjustment difficulty, and experiential avoidance and cognitive reappraisal partially mediated the relationship between mental health and veteran adjustment, with experiential avoidance being the stronger mediator. DISCUSSION: Our findings suggest that early assessment of experiential avoidance and cognitive reappraisal and the provision of relevant emotion regulation skills training could potentially reduce the veteran's need for more complex (and costly) psychological interventions in the future. Implications for veterans, as well as the services and professionals involved with veteran transition and health care are discussed. PMID- 29575288 TI - Shifting patterns of polyribosome accumulation at synapses over the course of hippocampal long-term potentiation. AB - Hippocampal long-term potentiation (LTP) is a cellular memory mechanism. For LTP to endure, new protein synthesis is required immediately after induction and some of these proteins must be delivered to specific, presumably potentiated, synapses. Local synthesis in dendrites could rapidly provide new proteins to synapses, but the spatial distribution of translation following induction of LTP is not known. Here, we quantified polyribosomes, the sites of local protein synthesis, in CA1 stratum radiatum dendrites and spines from postnatal day 15 rats. Hippocampal slices were rapidly fixed at 5, 30, or 120 min after LTP induction by theta-burst stimulation (TBS). Dendrites were reconstructed through serial section electron microscopy from comparable regions near the TBS or control electrodes in the same slice, and in unstimulated hippocampus that was perfusion-fixed in vivo. At 5 min after induction of LTP, polyribosomes were elevated in dendritic shafts and spines, especially near spine bases and in spine heads. At 30 min, polyribosomes remained elevated only in spine bases. At 120 min, both spine bases and spine necks had elevated polyribosomes. Polyribosomes accumulated in spines with larger synapses at 5 and 30 min, but not at 120 min. Small spines, meanwhile, proliferated dramatically by 120 min, but these largely lacked polyribosomes. The number of ribosomes per polyribosome is variable and may reflect differences in translation regulation. In dendritic spines, but not shafts, there were fewer ribosomes per polyribosome in the slice conditions relative to in vivo, but this recovered transiently in the 5 min LTP condition. Overall, our data show that LTP induces a rapid, transient upregulation of large polyribosomes in larger spines, and a persistent upregulation of small polyribosomes in the bases and necks of small spines. This is consistent with local translation supporting enlargement of potentiated synapses within minutes of LTP induction.

When heart transplantation began, patient survival was scarcely past a year[1], and the question of pregnancy for female heart transplant patients was not a significant consideration. Now, since the era of cyclosporine and conventional triple drug therapy, is important to anticipate that women of childbearing age may desire to become pregnant. Since the survival post-transplant for heart patients is an average of 10-12 years (with some surviving 20 years), this is not an unreasonable notion. This article is protected by copyright.

AB - Burning solid fuels to fulfill daily household energy needs results in chronic exposure to household air pollution (HAP), which is among the world's greatest health risks. This paper presents the results of a cross-sectional study of cookstove usage, fuel consumption, and indoor PM2.5 concentrations in rural and urban Honduran homes cooking with the Envirofit HM-5000 metal plancha stove (n = 32) as compared to control households using baseline cooking technologies (n = 33). Temperature-based stove usage measurements showed high HM-5000 acceptance, with significant displacement of the traditional cookstoves at both the urban (99%, P < .05) and rural study sites (75%, P < .05). However, longer-term usage data collected in peri-urban households showed that participants cooked on the HM 5000 more frequently during the 3-day monitoring period than during the following 3 weeks. Average indoor PM2.5 was 66% lower in HM-5000 households as compared to control households (P < .05). Lower indoor PM2.5 concentrations observed in participant homes as compared to control households, supported by high usage and traditional stove displacement, suggest the potential for the HM-5000 to yield health improvements in adopting Honduran households.

AB - Mycobacterium tuberculosis features a unique cell wall that protects the bacterium from the external environment. Disruption of the cell wall assembly is a promising direction for novel anti-tuberculotic drugs. A key component of the cell wall is galactan, a polysaccharide chain composed of galactofuranose (Galf) units connected by alternating beta-(1-5) and beta-(1-6) linkages. The majority of the galactan chain is biosynthesized by a bifunctional enzyme-galactofuranosyl transferase 2 (GlfT2). GlfT2 catalyzes two reactions: the formation of beta-(1-5) and beta-(1-6) linkages. It was suggested that the enzyme acts through a processive mechanism until it adds 30-35 Galf units in a single active site. We applied a QM/MM string method coupled with ab initio molecular dynamics simulations to study the two reactions catalyzed by GlfT2. We showed that both reactions proceed very similarly and feature similar transition-state structures. We also present novel information about the ring puckering behavior of the five membered furanose ring during the glycosyltransferase reaction and a calculated transition-state structure with galactose in a furanose form that may be used as a guide for the rational design of very specific and extremely potent inhibitors, that is, transition-state analogues, for GlfT2. Due to the absence of a furanose form of galactose in humans, transition-state-analogous inhibitors represent an attractive scaffold for the development of novel antibacterial drugs. PMID- 29575295 TI - Physical activity experiences in children post-liver transplant: Developing a foundation for rehabilitation interventions. AB - Physical Activity (PA) plays an important role in the physical and psychosocial health of children and is beneficial in the treatment and prevention of comorbidities associated with transplantation. Despite this, PA participation in pediatric liver transplant recipients remains low compared to healthy peers. This qualitative-focused mixed-methods study explored the PA experiences and parental perception of these experiences, including perceived facilitators and barriers to PA in children post-liver transplant. Eighteen participants (9 children [median age 10.8 years] and 9 parents) took part in semi-structured interviews and completed the PedsQL Multidimensional Fatigue Scale and PAQ. Most children reported they were physically active (PAQ median 3.08 [IQR] 2.60-3.51), participating in PA for its enjoyment, regardless of their level of motor proficiency. Levels of fatigue (median 65.28 [IQR] 56.25-90.97) were higher than healthy norms and impacted PA participation in some children. Children and parents perceived PA as central to post-transplant recovery and valued its social and mental health benefits; however, parents struggled with ongoing uncertainty and perceived physical vulnerability of their child. This study indicates the need for continuing PA support and education and provides valuable information for family-centered interventions to increase PA and improve health outcomes in children post-transplant. PMID- 29575298 TI - Hierarchical Self-Assembly Induced by Dilution-Enhanced Hydrophobic Hydration. AB - Hydrophobic hydration (HH) is crucial in protein chemistry. Its role in the organization of molecules in water, however, remains elusive and difficult to investigate without appropriate model systems. Metal carbonyl vesicles (MCsomes), assembled from hydrophobic Fp(CH2 )6 Azobenzenetrans (Fp head=(PPh3 )(Cp)Fe(CO)(CO-); hydrocarbon tail=(CH2 )6 Azobenzenetrans ; trans:trans configuration) is dispersible in water via HH of the Fp heads. We examined the dependence of this HH on solution conditions by taking advantage of redox activity and fluorescence quenching ability of hydrated Fe elements. A subtle variation in the HH substantially varied the solution behaviour of the MCsomes for hierarchical structural evolutions. This scrutiny resolved a long-standing challenge to explicate the role of HH in self-assembly at molecular levels, an imperative step to understand the biological systems. PMID- 29575296 TI - Modifications generated by fast photochemical oxidation of proteins reflect the native conformations of proteins. AB - Hydroxyl radical footprinting (HRF) is a nonspecific protein footprinting method that has been increasingly used in recent years to analyze protein structure. The method oxidatively modifies solvent accessible sites in proteins, which changes upon alterations in the protein, such as ligand binding or a change in conformation. For HRF to provide accurate structural information, the method must probe the native structure of proteins. This requires careful experimental controls since an abundance of oxidative modifications can induce protein unfolding. Fast photochemical oxidation of proteins (FPOP) is a HRF method that generates hydroxyl radicals via photo-dissociation of hydrogen peroxide using an excimer laser. The addition of a radical scavenger to the FPOP reaction reduces the lifetime of the radical, limiting the levels of protein oxidation. A direct assay is needed to ensure FPOP is probing the native conformation of the protein. Here, we report using enzymatic activity as a direct assay to validate that FPOP is probing the native structure of proteins. By measuring the catalytic activity of lysozyme and invertase after FPOP modification, we demonstrate that FPOP does not induce protein unfolding. PMID- 29575297 TI - Sonodynamic therapy-assisted immunotherapy: A novel modality for cancer treatment. AB - Sonodynamic therapy (SDT), which is based on photodynamic therapy (PDT), is a new cancer treatment modality. Unlike PDT, which has poor tissue penetration, ultrasound can penetrate deeply into tissues and largely target tumor tissue to mediate the cytotoxicity of sonosensitizers. We hypothesize that, similar to PDT, SDT may perform effectively as a cancer vaccine. Thus, we developed a therapeutic strategy to explore whether SDT can eliminate primary tumors, inhibit metastases, and prevent tumor relapse. In the present study, we found that HiPorfin (HPD) induced SDT killed tumor cells, promoted calreticulin expression on the cell surface and elicited immune responses. Meanwhile, we observed that SDT induced functional antitumor vaccination and abscopal effects in H22 tumor-bearing mice. Furthermore, this strategy conferred an immunological memory, which could protect against tumor recurrence after the elimination of the initial tumor. These results showed important effects of SDT on immune responses. PMID- 29575300 TI - The costs and benefits of pollinator dependence: empirically based simulations predict raspberry fruit quality. AB - Globally, agriculture increasingly depends on pollinators to produce many seed and fruit crops. However, what constitutes optimal pollination service for pollinator-dependent crops remains unanswered. We developed a simulation model to identify the optimal pollination service that maximizes fruit quality in crops. The model depicts the pollination (i.e., autonomous self-fertilization, pollen deposition) and post-pollination (i.e., pollen germination, and time from germination to ovule fertilization) processes leading to fruit and seed set and allows for negative flower-pollinator interactions, specifically pistil damage. We parameterized and validated the model based on empirical observations of commercial raspberry in western Argentina. To assess the effects of pollination intensity for fruit production, we conducted simulations over a range of visit number per flower by the two primary managed pollinators worldwide, Apis mellifera and Bombus terrestris. Simulations identified that ~15-35 visits per flower by A. mellifera or ~10-20 visits by B. terrestris provide adequate pollination and maximize raspberry fruit quality (i.e., estimated as the proportion of ovules that develop into drupelets). Visits in excess of these optima reduce simulated fruit quality, and flowers receiving >670 honey bee visits or >470 bumble bee visits would produce fruits of poorer quality than those receiving no bee visits. The simulations generated consistent, unbiased predictions of fruit quality for 12 raspberry fields. This model could be adapted easily to other animal-pollinated crops and used to guide efficient pollinator management in any agro-ecosystem. PMID- 29575299 TI - The PLGF/c-MYC/miR-19a axis promotes metastasis and stemness in gallbladder cancer. AB - Gallbladder cancer (GBC) is the most common malignant tumor of the biliary tract system. Epithelial-mesenchymal transition (EMT) plays a vital role in the process of tumor metastasis. Mesenchymal-like cells can serve as a source of cancer stem cells, which can confer the EMT phenotype. Placental growth factor (PLGF) belongs to the vascular endothelial growth factor family and plays a vital role in cancer. However, the underlying molecular mechanisms about the influence of PLGF on EMT in GBC remain unknown. Here we show that PLGF expression levels were higher in GBC tissues than in normal adjacent tissues and were associated with poor prognosis in GBC patients. Exogenous PLGF enhanced the migration, invasion, and tumorsphere formation of GBC cells. Conversely, knockdown of PLGF decreased the aggressive phenotype of GBC cells. Mechanistically, exogenous PLGF upregulated microRNA-19a (miR-19a) expression through the activation of c-MYC. Moreover, Spearman's correlation analysis showed a positive pairwise correlation among PLGF, c-MYC, and miR-19a expression in GBC tissues. Taken together, these results suggest that PLGF promotes EMT and tumorsphere formation through inducing miR-19a expression by upregulating c-MYC. Thus, PLGF could be a promising molecular therapeutic target for GBC. PMID- 29575301 TI - Position-specific 13 C/12 C analysis of amino acid carboxyl groups - automated flow-injection analysis based on reaction with ninhydrin. AB - RATIONALE: The fundamental level of stable isotopic knowledge lies at specific atomic positions within molecules but existing methods of analysis require lengthy off-line preparation to reveal this information. An automated position specific isotope analysis (PSIA) method is presented to determine the stable carbon isotopic compositions of the carboxyl groups of amino acids (delta13 CCARBOXYL values). This automation makes PSIA measurements easier and routine. METHODS: An existing high-performance liquid chromatography (HPLC) gas handling interface/stable isotope ratio mass spectrometry system was modified by the addition of a post-column derivatisation unit between the HPLC system and the interface. The post-column reaction was optimised to yield CO2 from the carboxyl groups of amino acids by reaction with ninhydrin. RESULTS: The methodology described produced delta13 CCARBOXYL values with typical standard deviations below +/-0.1 0/00 and consistent differences (Delta13 CCARBOXYL values) between amino acids over a 1-year period. First estimates are presented for the delta13 CCARBOXYL values of a number of internationally available amino acid reference materials. CONCLUSIONS: The PSIA methodology described provides a further dimension to the stable isotopic characterisation of amino acids at a more detailed level than the bulk or averaged whole-molecule level. When combined with on-line chromatographic separation or off-line fraction collection of protein hydrolysates the technique will offer an automated and routine way to study position-specific carboxyl carbon isotope information for amino acids, enabling more refined isotopic studies of carbon uptake and metabolism. PMID- 29575302 TI - Underlying maternal and pregnancy-related conditions account for a substantial proportion of neonatal morbidity in late preterm infants. AB - AIM: We studied the impact of maternal and pregnancy-related conditions and the effect of gestational age itself, on the health of infants born late preterm. METHODS: Singletons born in gestational weeks 34 + 0 to 41 + 6 in 1995-2013 in the southern region of Sweden were identified from a perinatal register. We found 14 030 infants born late preterm and 294 814 born at term. A hierarchical system was developed to examine the impact of pregnancy complications. The outcomes studied were as follows: neonatal death, central nervous system (CNS) or respiratory disease, infection, neonatal admission and respiratory support. Odds ratios (OR) and 95% confidence intervals (95% CI) were obtained using logistic regression analyses. RESULTS: Late preterm infants were at increased risk for all outcomes compared to term infants, with adjusted ORs from 13.1 (95% CI: 12.7 13.6) for neonatal admission to 2.3 (95% CI: 1.8-2.9) for infections. Late preterm birth after preterm prelabour rupture of membranes was associated with an overall lower risk compared to late preterm births due to other causes. Exposure to antepartum haemorrhage or maternal diabetes increased the risk for CNS and respiratory morbidity. CONCLUSION: Morbidity decreased in late preterm infants with increasing gestational age. Underlying conditions accounted for a substantial part of the morbidity.

AB - OBJECTIVE: To compare the performance of three placental growth factor (PlGF) based tests in predicting delivery within 14 days from testing in women with suspected preterm pre-eclampsia before 35 weeks' gestation. METHODS: This was a retrospective analysis of samples collected from three prospective pregnancy cohort studies. Participants were pregnant women with suspected preterm pre eclampsia recruited in tertiary maternity units in the UK and Ireland. Samples were analyzed simultaneously according to the manufacturers' directions. The tests compared were the DELFIA Xpress PlGF 1-2-3 test, the Triage PlGF test and the Elecsys immunoassay soluble fms-like tyrosine kinase-1 (sFlt-1)/PlGF ratio. Areas under receiver-operating characteristics curves (AUCs) were compared. The main outcome measure was detection of a difference of 0.05 in AUC between tests for delivery within 14 days of testing. RESULTS: Plasma samples from 396 women and serum samples from 244 women were assayed. In predicting delivery within 14 days secondary to suspected pre-eclampsia prior to 35 weeks' gestation, no significant differences were observed in AUCs (P = 0.795), sensitivities (P = 0.249), positive predictive values (P = 0.765) or negative predictive values (P = 0.920) between the three tests. The specificity of the Elecsys sFlt-1/PlGF ratio test was higher than that of the other two tests (P < 0.001). CONCLUSIONS: The tests perform similarly in their prediction of need for delivery within 14 days in women with suspected pre-eclampsia. The high negative predictive values support the role of PlGF-based tests as 'rule-out' tests for pre-eclampsia. (c) 2018 Authors.

AB - In this Scientific Perspectives we first review the recent advances in our understanding of the functional architecture of basal ganglia circuits. Then we argue that these data can best be explained by a model in which basal ganglia act to control the gain of movement kinematics to shape performance based on prior experience, which we refer to as a history-dependent gain computation. Finally, we discuss how insights from the history-dependent gain model might translate from the bench to the bedside, primarily the implications for the design of adaptive deep brain stimulation. Thus, we explicate the key empirical and conceptual support for a normative, computational model with substantial explanatory power for the broad role of basal ganglia circuits in health and disease.

AB - Multiple functions have been proposed for transcription factor FoxM1, including the regulation of cell proliferation, differentiation, senescence, apoptosis, and tissue homeostasis. However, the role of FoxM1 in muscle satellite cells (SCs) remains unclear. In the present study, we demonstrated that FoxM1 was essential for the proliferation and survival of SCs. Crucially, we found that long noncoding RNAs (lncRNAs) Snhg8 and Gm26917 significantly regulated the proliferation and apoptosis of SCs, respectively, and these lncRNAs were directly regulated by FoxM1 in SCs. Mechanistically, Snhg8 sustained SCs proliferation by promoting the transcription of ribosomal proteins, while Gm26917 acted as a competing endogenous RNA for microRNA-29b, which accelerated apoptosis of SCs. In mice, conditional knockout of FoxM1 in skeletal muscle resulted in decreased proliferation and increased apoptosis of SCs. Thus, our studies revealed a previously unrecognized role of FoxM1 in SCs and uncovered two lncRNAs, Snhg8 and Gm26917, which function as novel targets of FoxM1 in the regulation of SCs proliferation and survival.

AB - BACKGROUND: The few studies that evaluated taste function in Parkinson's disease (PD) showed inconsistent results. The inherited ability to taste the bitter compound of 6-n-propylthiouracil has been considered to be a paradigm of general taste perception. 6-n-propylthiouracil taste perception is mediated by the TAS2R38 receptor, and reduced 6-n-propylthiouracil sensitivity has been associated with several diseases not typically related to taste function. OBJECTIVES: We evaluated the 6-n-propylthiouracil taste perception and the TAS2R38 gene as genetic risk factors for the development of idiopathic PD in PD patients and healthy controls (HC). METHODS: The 6-n-propylthiouracil taste perception was assessed by testing the responsiveness, and the ability to recognize, 6-n-propylthiouracil and sodium chloride. The participants were classified for 6-n-propylthiouracil taster status and genotyped for the TAS2R38 gene. RESULTS: A significant increase in the frequency of participants classified as 6-n-propylthiouracil nontasters and a reduced ability to recognize bitter taste quality of 6-n-propylthiouracil were found in PD patients when compared with healthy controls. The results also showed that only 5% of PD patients had the homozygous genotype for the dominant tasting variant of TAS2R38, whereas most of them carried the recessive nontaster form and a high number had a rare variant. CONCLUSIONS: Our results show that 6-n-propylthiouracil taster status and TAS2R38 locus are associated with PD. The 6-n-propylthiouracil test may therefore represent a novel, simple way to identify increased vulnerability to PD. Moreover, the presence of the nontasting form of TAS2R38 in PD may further substantiate that disease-associated taste disruption may represent a risk factor associated with the disease.

AB - INTRODUCTION: Lung ultrasound is gaining consensus for the diagnosis of some pulmonary conditions. Pulmonary complications are common in pediatric cardiac surgery. However, its use remains limited in this setting. Our aim was to test the feasibility of lung ultrasound following pediatric cardiac surgery and to compare lung ultrasound and chest X-ray findings, assessing whether lung ultrasound may provide additional information. METHODS: One hundred and thirty eight lung ultrasound examinations were performed in 79 children (median age 9.3 months) at different time points after surgery. For each hemithorax, 3 areas (anterior/lateral/posterior) have been evaluated in the upper and lower halves of the chest (for a total of 6 scanning sites per side). Pleural effusion, atelectasis, and the number of B-lines were investigated. RESULTS: Lung ultrasound was feasible in all cases in at least 1 of the 3 areas. Feasibility was different for the lateral, posterior, and anterior areas (100%, 90%, and 78%, respectively). The posterior areas were more sensitive than anterior and lateral ones in the diagnosis of effusion/atelectasis. In 81 cases, lung ultrasound allowed reclassification of chest X-ray findings, including 40 new diagnoses (diagnosis of effusion/atelectasis with negative chest X-ray reports) and 41 changes in diagnosis (effusions reclassified as atelectasis/severe congestion or vice versa). Although new diagnosis of small-to-moderate effusion/atelectasis was of limited clinical value, in 29 cases the new diagnosis changed the therapeutic approach. CONCLUSION: Lung ultrasound is feasible and accurate for the diagnosis of common pulmonary conditions after pediatric cardiac surgery, allowing reclassification of chest X-ray findings in a significant number of patients.

AB - Catalytic hydrodefluorination (HDF) of unactivated fluoroalkanes or CF3 substituted aryl species is performed using the PIII Lewis acids, [(bipy)PPh]2+ (12+ ) and [(terpy)PPh]2+ (22+ ) under mild conditions (25 or 50 degrees C). Mechanistic studies indicate that activation of C-F bond by the PIII center is key. Particularly noteworthy is that the catalyst 2[B(C6 F5 )4 ]2 is air-stable and readily accessible from bench-stable, commercially available reagents in one step and can be used without isolation.

AB - A new hexadecahedron assembled by core-shell CoS2 particles@N-doped carbon (CoS2 @NCH) is prepared successfully through the self-templating method. The CoS2 @NCH hybrid electrode delivers a high lithium-storage capacity of 778 mA h g-1 after 1000 cycles at a high current density of 1 A g-1 , which is the longest cycle lifespan among the reported CoS2 anode materials in lithium-ion batteries. Furthermore, the CoS2 @NCH hybrid electrode shows excellent rate capability with a discharge capacity of 220 mA h g-1 at an extremely high current density of 20 A g-1 , and a charge capacity of 649 mA h g-1 is restored upon returning the current density back to 2 A g-1 . The superior performance is attributed to the unique construction of CoS2 @NCH. The N-doped interconnected porous carbon shells form highly conductive skeletons for quick electron transfer and prevent the electrode from collapsing. Moreover, the porous characteristic of the materials plays a key role: as some effective channels, the mesopores on the porous carbon shells provide greater access for lithium, and the mesopores derived from the particle interspace enables the complete immersion of the electrodes in electrolyte, which alleviates the volume expansion and ensures the integrity of the electrode. In addition, the nanosized CoS2 particles, which shorten the ion transport path and provide extra electroactive sites, also improve the reaction kinetics.

AB - Infection due to species other than Candida albicans is increasing among solid organ transplant recipients. Candida utilis, commonly used in the food industry, is considered as a low-virulence yeast. We report the first case of C. utilis fungaemia involving a solid organ transplant recipient. The infection was triggered by the withdrawal of a ureteral stent and was successfully treated with intravenous micafungin.

AB - Many scientific articles proved that green tea (GT), Camellia sinensis, has a great potential to manage central nervous system, cardiovascular, and metabolic diseases and treat cancer and inflammatory disorders. However, it is important to consider that "natural" is not always "safe." Some relevant articles reported side effects of GT, detrimental effects on health. The aim of this study is to provide a classified report about the toxicity of GT and its main constituents in acute, subacute, subchronic, and chronic states. Furthermore, it discusses on the cytotoxicity, genotoxicity, mutagenicity, carcinogenicity, and developmental toxicity of GT and its main constituents. The most important side effects have been reported hepatotoxicity and gastrointestinal disorders specially while consumed on an empty stomach. GT and its main components are not major teratogen, mutagen, or carcinogen substances. However, there is limited data in using them during pregnancy, and they should be used with caution in pregnancy, breast feeding, and susceptible people. Because GT and its main components have a wide variety of drug interactions, consideration should be taken in coadministration of them with narrow therapeutic indexed drugs. Furthermore, they evoke selective cytotoxicity on cancerous cells that could engage them as an adjuvant substance in cancer therapy. PMID- 29575317 TI - Measuring Spin Relaxation Rates Using Satellite Exchange NMR Spectroscopy. AB - An approach to the indirect measurement of nuclear spin relaxation rates of low magnetogyric ratio (gamma) nuclei using the process of satellite exchange is described. The method does not require the observation of, or even the ability to provide radio-frequency pulses to, the low-gamma nucleus, but requires this to be scalar coupled to an NMR observable nucleus, such as 31 P or 1 H, making it especially attractive for the study of diamagnetic transition metals. In situations where spin relaxation is dominated by chemical shift anisotropy (CSA), the determination of the longitudinal spin relaxation time constant (T1 ) of the metal becomes possible, as illustrated for 195 Pt and 107/109 Ag.

AB - Oncogene c-Src has been found to be a potential target for the treatment of triple-negative breast cancer (TNBC). However, the therapeutic effects of the c Src inhibitor on TNBC patients are controversial compared to those on cell lines. The molecular mechanisms of the inhibitory effects of the c-Src inhibitor on TNBC remain unclear. Herein, we showed that a specific c-Src inhibitor, PP2, was effective in inhibiting phosphorylation of c-Src in 4 cell lines: T-47D, SK-BR-3, SUM1315MO2, and MDA-MB-231, regardless of hormone receptors and human epidermal growth factor receptor 2 (HER2) expression levels. Giving PP2 preferentially reduced the S phase of cell cycles and inhibited colony formation in SUM1315MO2 and MDA-MB-231, but not in SK-BR-3 and T-47D cells. Furthermore, PP2 effectively blocked cell migration/invasion and epithelial-mesenchymal transition (EMT) in TNBC cell lines, SUM1315MO2 and MDA-MB-231. An EMT biomarker, vimentin, was highly expressed in 2 TNBC cell lines when they were compared with SK-BR-3 and T 47D cells. Further depletion of vimentin by shRNA remarkably attenuated the inhibitory effects of the c-Src inhibitor on TNBC cells in vitro and in vivo, indicating a crucial action of vimentin to affect the function of c-Src in TNBC. This study provides an important rationale for the clinic to precisely select TNBC patients who would benefit from c-Src inhibitor treatment. This finding suggests that traditional markers for TNBC are not sufficient to precisely define this aggressive type of cancer. Vimentin is identified as an important biomarker to enable categorization of TNBC.

AB - The objective of this study was to assess the availability and readiness of the primary health care (PHC) services of commune health centers (CHCs) in Quoc Oai, a rural district of Northern Vietnam based on the World Health Organization's Service Availability and Readiness Assessment (SARA) tool. The study was done in 2 steps. First, the heads of the 21 CHCs of Quoc Oai district were interviewed using SARA, a quantitative survey, and the responses were then validated by direct observations of each facility. The results showed that although the average number of health staffs in each CHC met the national standards (at least 5 staffs per CHC), its allocation within each CHC was not properly met because some CHCs had only 2 health staffs. Several health equipment and facilities were not fully available in many CHCs, and although the majority of the PHC services were available at the CHCs, their readiness remained limited. Several significant correlates between the availability of health care workers and the availability of the facilities and the PHC services were observed, suggesting that they depend upon and affect one another in the health system. Using the SARA-based inventory, the study helps health managers and policy makers to prioritize efforts and allocate resources more appropriately. To be effective, attention should be given to how to make facilities, services, and human resources for health ready for PHC activities-more investment and support from the system (from higher to lower level) and the government.

AB - OBJECTIVE: The aim of this study was to compare the global DNA methylation levels in patients under bruxism treatment and a control group. METHODS: Subjects undergoing bruxism treatment were classified in awake bruxism (42 patients), sleep bruxism (32 patients) and both conditions (42 patients). The control group included 42 individuals. A colorimetric assay (MethylFlash Methylated DNA 5-mC Quantification Kit, Epigenetic Group Inc., NY, USA) was used to determine the global DNA methylation levels. RESULTS: Statistically significant differences were found in amounts of methylated DNA in all circadian manifestations of bruxism compared with a control group (sleep bruxism = 0.95% +/- 2.02%; awake bruxism = 0.87% +/- 2.1%; sleep and awake bruxism = 0.17% +/- 0.25%; Control = 1.69% +/- 1.6%; Kruskal-Wallis test [p = .0001] followed by Dunn's test [p < .05]). CONCLUSION: Patients undergoing bruxism treatment exhibited hypomethylated DNA levels when compared to control group. Our results suggest that DNA hypomethylation might be a novel aetiologic factor in bruxism aetiology. Further researches must be performed exploring the role of epigenetics modifications in circadian manifestations of bruxism. PMID- 29575323 TI - Clozapine reduces nicotine self-administration, blunts reinstatement of nicotine seeking but increases responding for food. AB - People with schizophrenia display significantly higher rates of smoking than the general population, which may be due to an interaction between nicotine and antipsychotic medication. While the conventional antipsychotic drug haloperidol sometimes increases cigarette smoking in patients with schizophrenia, there is some evidence suggesting that clozapine, an atypical antipsychotic drug, may reduce nicotine use in these patients. However, the effects of antipsychotic drugs like clozapine on aspects of nicotine self-administration and reinstatement have not been systematically examined. In the current study, we assessed the effect of clozapine on nicotine self-administration under fixed ratio and progressive ratio schedules of reinforcement, as well as reinstatement of nicotine-seeking following a period of abstinence. To determine the specificity of its effect on nicotine reward, we also tested the effect of clozapine on responding for food reinforcement under fixed ratio and progressive ratio schedules. For comparison, we also examined the effects of haloperidol, a first generation antipsychotic drug, under some of the same behavioral conditions as clozapine. We show that clozapine inhibits nicotine self-administration and reinstatement of nicotine-seeking but also increases the amount of effort that rats will exert for food reward. In contrast, haloperidol at a wide range of doses attenuated responding for nicotine and food reward, suggestive of a non specific reduction in reinforcer efficacy. These results show the potential utility of clozapine as a smoking cessation treatment for patients with schizophrenia, in addition to its antipsychotic properties. PMID- 29575325 TI - Neural Stem Cell Grafts Promote Astroglia-Driven Neurorestoration in the Aged Parkinsonian Brain via Wnt/beta-Catenin Signaling. AB - During aging-one the most potent risk factors for Parkinson's disease (PD)-both astrocytes and microglia undergo functional changes that ultimately hamper homoeostasis, defense, and repair of substantia nigra pars compacta (SNpc) midbrain dopaminergic (mDA) neurons. We tested the possibility of rejuvenating the host microenvironment and boosting SNpc DA neuronal plasticity via the unilateral transplantation of syngeneic neural stem/progenitor cells (NSCs) in the SNpc of aged mice with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced experimental PD. Transplanted NSCs within the aged SNpc engrafted and migrated in large proportions to the tegmental aqueduct mDA niche, with 30% acquiring an astroglial phenotype. Both graft-derived exogenous (ex-Astro) and endogenous astrocytes (en-Astro) expressed Wnt1. Both ex-Astro and en-Astro were key triggers of Wnt/beta-catenin signaling in SNpc-mDA neurons and microglia, which was associated with mDA neurorescue and immunomodulation. At the aqueduct-ventral tegmental area level, NSC grafts recapitulated a genetic Wnt1-dependent mDA developmental program, inciting the acquisition of a mature Nurr1+ TH+ neuronal phenotype. Wnt/beta-catenin signaling antagonism abolished mDA neurorestoration and immune modulatory effects of NSC grafts. Our work implicates an unprecedented therapeutic potential for somatic NSC grafts in the restoration of mDA neuronal function in the aged Parkinsonian brain. Stem Cells 2018;36:1179-1197. PMID- 29575326 TI - The CRISPR/Cas revolution reaches the RNA world: Cas13, a new Swiss Army knife for plant biologists. AB - Application of the bacterial CRISPR/Cas systems to eukaryotes is revolutionizing biology. Cas9 and Cas12 (previously called Cpf1) are widely used as DNA nucleases for inducing site-specific DNA breaks for different kinds of genome engineering applications, and in their mutated forms as DNA-binding proteins to modify gene expression. Moreover, histone modifications, as well as cytosine methylation or base editing, were achieved with these systems in plants. Recently, with the discovery of the nuclease Cas13a (previously called C2c2), molecular biologists have obtained a system that enables sequence-specific cleavage of single-stranded RNA molecules. The latest experiments with this and also the alternative Cas13b system demonstrate that these proteins can be used in a similar manner in eukaryotes for RNA manipulation as Cas9 and Cas12 for DNA manipulations. The first application of Cas13a for post-transcriptional regulation of gene expression in plants has been reported. Recent results show that the system is also applicable for combating viral infection in plants. As single-stranded RNA viruses are by far the most abundant class of viruses in plants, the application of this system is of special promise for crops. More interesting applications are imminent for plant biologists, with nuclease dead versions of Cas13 enabling the ability to visualize RNA molecules in vivo, as well as to edit different kinds of RNA molecules at specific bases by deamination or to modify them by conjugation. Moreover, by combining DNA- and RNA-directed systems, the most complex of changes in plant metabolism might be achievable.

AB - Alzheimer's disease (AD) is associated with extensive alterations in grey matter microstructure, but our ability to quantify this in vivo is limited. Neurite orientation dispersion and density imaging (NODDI) is a multi-shell diffusion MRI technique that estimates neuritic microstructure in the form of orientation dispersion and neurite density indices (ODI/NDI). Mean values for cortical thickness, ODI, and NDI were extracted from predefined regions of interest in the cortical grey matter of 38 patients with young onset AD and 22 healthy controls. Five cortical regions associated with early atrophy in AD (entorhinal cortex, inferior temporal gyrus, middle temporal gyrus, fusiform gyrus, and precuneus) and one region relatively spared from atrophy in AD (precentral gyrus) were investigated. ODI, NDI, and cortical thickness values were compared between controls and patients for each region, and their associations with MMSE score were assessed. NDI values of all regions were significantly lower in patients. Cortical thickness measurements were significantly lower in patients in regions associated with early atrophy in AD, but not in the precentral gyrus. Decreased ODI was evident in patients in the inferior and middle temporal gyri, fusiform gyrus, and precuneus. The majority of AD-related decreases in cortical ODI and NDI persisted following adjustment for cortical thickness, as well as each other. There was evidence in the patient group that cortical NDI was associated with MMSE performance. These data suggest distinct differences in cortical NDI and ODI occur in AD and these metrics provide pathologically relevant information beyond that of cortical thinning. PMID- 29575328 TI - Polycarboxylate-Templated Coordination Polymers: Role of Templates for Superprotonic Conductivities of up to 10-1 S cm-1. AB - Three coordination polymers (CPs) have been synthesized based on a [Co(bpy)(H2 O)4 ]2+ chain (bpy=4,4'-bipyridine) by a template approach. The frameworks are neutralized by different templated polycarboxylate anions (furan di-carboxylate (fdc) in Co-fdc, benzene tri-carboxylate (btc) in Co-tri and benzene tetra carboxylate (btec) in Co-tetra). These templates with different degrees of protonation and ionic carrier concentration played significant role on crystal packing as well as formation of well-directed H-bonded networks which made these CPs perform well in proton conduction (PC). The PC value reaches to 1.49*10-1 S cm-1 under 80 degrees C and 98 % relative humidity (R.H.) for Co-tri, which is the highest among CPs/MOFs/COFs and is an example of conductivity in the order of 10-1 S cm-1 . Co-tri and Co-tetra are excellent proton conductors at mild temperature (40 degrees C) and 98 % R.H. (conductivities up to 2.92*10-2 and 1.38*10-2 S cm-1 , respectively). PMID- 29575327 TI - Changes in the proteome of the problem weed blackgrass correlating with multiple herbicide resistance. AB - Herbicide resistance in grass weeds is now one of the greatest threats to sustainable cereal production in Northern Europe. Multiple-herbicide resistance (MHR), a poorly understood multigenic and quantitative trait, is particularly problematic as it provides tolerance to most classes of chemistries currently used for post-emergence weed control. Using a combination of transcriptomics and proteomics, the evolution of MHR in populations of the weed blackgrass (Alopecurus myosuroides) has been investigated. While over 4500 genes showed perturbation in their expression in MHR versus herbicide sensitive (HS) plants, only a small group of proteins showed >2-fold changes in abundance, with a mere eight proteins consistently associated with this class of resistance. Of the eight, orthologues of three of these proteins are also known to be associated with multiple drug resistance (MDR) in humans, suggesting a cross-phyla conservation in evolved tolerance to chemical agents. Proteomics revealed that MHR could be classified into three sub-types based on the association with resistance to herbicides with differing modes of action (MoA), being either global, specific to diverse chemistries acting on one MoA, or herbicide specific. Furthermore, the proteome of MHR plants were distinct from that of HS plants exposed to a range of biotic (insect feeding, plant-microbe interaction) and abiotic (N-limitation, osmotic, heat, herbicide safening) challenges commonly encountered in the field. It was concluded that MHR in blackgrass is a uniquely evolving trait(s), associated with changes in the proteome that are distinct from responses to conventional plant stresses, but sharing common features with MDR in humans. PMID- 29575329 TI - Hunting the main player enabling Chlamydomonas reinhardtii growth under fluctuating light. AB - Photosynthetic organisms have evolved numerous photoprotective mechanisms and alternative electron sinks/pathways to fine-tune the photosynthetic apparatus under dynamic environmental conditions, such as varying carbon supply or fluctuations in light intensity. In cyanobacteria flavodiiron proteins (FDPs) protect the photosynthetic apparatus from photodamage under fluctuating light (FL). In Arabidopsis thaliana, which does not possess FDPs, the PGR5-related pathway enables FL photoprotection. The direct comparison of the pgr5, pgrl1 and flv knockout mutants of Chlamydomonas reinhardtii grown under ambient air demonstrates that all three proteins contribute to the survival of cells under FL, but to varying extents. The FDPs are crucial in providing a rapid electron sink, with flv mutant lines unable to survive even mild FL conditions. In contrast, the PGRL1 and PGR5-related pathways operate over relatively slower and longer time-scales. Whilst deletion of PGR5 inhibits growth under mild FL, the pgrl1 mutant line is only impacted under severe FL conditions. This suggests distinct roles, yet a close relationship, between the function of PGR5, PGRL1 and FDP proteins in photoprotection. PMID- 29575330 TI - Clinician researcher career pathway for registered nurses and midwives: A proposal. AB - AIM: To consider clinician researcher career frameworks and propose a new pathway, integrating university and health service components to support research career progression within nursing and midwifery practice. BACKGROUND: Hospitals with research-active clinicians report fewer adverse events and better patient outcomes. Nursing clinician researcher career development is therefore an international priority, yet positions and expectations associated with this are not always well articulated, with nurses and midwives challenged to accommodate research and clinical careers. DESIGN: This discussion paper describes nurse/midwife clinician researcher career frameworks and a new pathway that aligns academic and nursing role descriptions. DATA SOURCES: The new framework was informed by a brief literature search for international framework documents, three Australian state-based Nurses and Midwives Awards: the Australian Qualifications Framework, publically available University Academic (Research) Award schedules and academic staff descriptions, and state health department and health services publications. IMPLICATIONS FOR NURSING: The implementation of research-based practice is a key element of nursing and midwifery roles and "advanced practice" position descriptions have well-defined research expectations. This paper considers structures to support their achievement. CONCLUSION: This paper provides a blueprint for clinician researcher career development. It elevates the research domain as an equal alongside clinical, managerial and educational clinical career development. PMID- 29575331 TI - Retrospective Case Series on the Treatment of Painful Diabetic Peripheral Neuropathy With Dorsal Root Ganglion Stimulation. AB - BACKGROUND: The dorsal root ganglion (DRG) has been identified as an important neural structure in the development and maintenance of chronic pain. We present a retrospective case series of patients with refractory painful diabetic peripheral neuropathy (PDPN) that underwent electrical stimulation of the DRG and report on changes in their overall perceived pain and complication rates. METHODS: Ten diabetic males (mean age 65.2 [SD 8.8] years) with painful symptoms of the lower limbs were enrolled and trialed with up to four quadripolar percutaneous DRG stimulation leads between L2 and L5 spinal levels. Patients received a fully implantable neurostimulation system (Abbott Laboratories, Sunnyvale, CA, USA) immediately or after a successful trial period (>50% reduction in pain). Overall perceived pain was measured by visual analogue scale (VAS) at baseline, one-week postimplantation and one-, three-, six-, and twelve-month follow-up (n = 5). RESULTS: Ten patients were included in this retrospective study. Seven of these subjects received permanent stimulator implants after successful externalized or intraoperative trials. Two of those patients subsequently required explantation, due to failure to capture primary pain area (n = 1) and personal reasons (n = 1). For the five subjects that proceeded to clinical follow-ups, baseline VAS was reduced by an average of 63.90% (SD 21.39; p < 0.001) postimplantation. For four patients with available 12-month follow-up data, mean relative reduction in overall perceived pain averaged 64.16% (SD 35.8; p< 0.001). CONCLUSION: Early findings from this small retrospective case series, suggest DRG is a safe and effective neuromodulation modality to improve painful symptoms in PDPN patients. Future prospective trials are required to further investigate the use of DRG stimulation for this clinical indication. PMID- 29575332 TI - Outcome after high-dose chemotherapy and autologous stem cell transplantation in patients with aggressive B-cell non-Hodgkin's lymphoma. AB - OBJECTIVE: For more than two decades, high-dose chemotherapy (HDT) and autologous blood stem cell transplantation (ABSCT) were treatment options for patients with aggressive B-cell non-Hodgkin's lymphoma (B-NHL). However, the ideal timing and the collective patient benefits are still being debated. METHOD: We retrospectively analyzed the data of 163 patients with B-NHL who received an HDT protocol followed by ABSCT between 2001 and 2007. Patients were analyzed according to the time point of HDT/ABSCT to compare upfront (directly after induction, n = 72, 44%) versus secondary transplantation (at first relapse, n = 91, 56%). RESULTS: The overall response rate was 100% and 94% after upfront and secondary HDT/ABSCT, respectively. No significant differences were found for hematopoietic recovery and toxicity profile. The progression-free survival (PFS) and overall survival (OS) probability were found to be significantly higher in the upfront HDT/ABSCT treatment group (P = .018 and P = .004). In multivariate analysis, upfront HDT/ABSCT and low IPI risk score had a significant beneficial effect on OS (P = .031 and P = .019). CONCLUSION: HDT and ABSCT directly after induction chemotherapy were confirmed to be feasible with high PFS and OS rates. In addition, for patients with relapse after first-line therapy and consecutively poor prognosis, HDT/ABSCT also offers an effective treatment strategy.

The aim of the study was to investigate the differences in gene expression profiles of IMECs upon glucose toxicity exposure and insulin treatment. METHODS: IMECs were treated with 5.6 mmol L-1 glucose, 35 mmol L-1 glucose, and 35 mmol L-1 glucose plus 10-8 mol L-1 insulin, respectively. Gene expression profiles were determined by microarray and verified by qPCR. GO terms and KEGG analysis were performed to assess the potential roles of differentially expressed genes. The interaction and expression tendency of differentially expressed genes were analyzed by Path-Net algorithm. RESULTS: Compared with glucose toxicity-exposed IMECs, 1574 mRNAs in control group and 2870 mRNAs in insulin-treated IMECs were identified with differential expression, respectively. GO and KEGG pathway analysis revealed that these genes conferred roles in regulation of apoptosis, proliferation, migration, adhesion, and metabolic process etc. Additionally, MAPK signaling pathway and apoptosis were the dominant nodes in Path-Net. IMECs survival and function pathways were significantly changed, and the expression tendency of genes from euglycemia and glucose toxicity exposure to insulin treatment was revealed and enriched in 7 patterns. CONCLUSIONS: Our study provides a microcirculatory framework for gene expression profiles of glucose toxicity-exposed IMECs. PMID- 29575335 TI - Three-dimensional Kendrick mass plots as a tool for graphical lipid identification. AB - RATIONALE: The rising field of lipidomics strongly relies on the identification of lipids in complex matrices. Recent technical advances regarding liquid chromatography (LC) and high-resolution mass spectrometry (HRMS) enable the mapping of the lipidome of an organism with short data acquisition times. However, interpretation and evaluation of resulting multidimensional datasets are challenging and this is still the bottleneck regarding overall analysis times. METHODS: A novel adaption of Kendrick mass plot analysis is presented for a rapid and accurate analysis of lipids in complex matrices. Separation of lipids by their respective head group was achieved via hydrophilic interaction liquid chromatography (HILIC) coupled to HRMS. The resulting LC/HRMS datasets are processed to a list of chromatographically separated features by applying an optimized MZmine 2 workflow. All features are plotted in a three-dimensional Kendrick mass plot, which allows a fast identification of present lipid classes, based on equidistant features with fitting retention times and the same Kendrick mass defect. Suspected lipid classes are used for exact mass database matching to annotate features. A second three-dimensional Kendrick mass plot of annotated features of a single lipid class helps to reveal potential database mismatches, resulting in a curated list of identified lipid species. RESULTS: The use of the novel adaption of the Kendrick mass plot has accelerated the identification of the relevant lipid species in the green alga Chlamydomonas reinhardtii. A total of 106 species were identified within the lipid classes: phosphatidylserine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, monogalactosyldiacylglycerol, digalactosyldiacylglycerol, and sulfoquinovosyldiacylglycerol. CONCLUSIONS: This work shows how the addition of chromatographic information, i.e. the retention time, to a classical two dimensional Kendrick mass plot enables rapid and accurate analysis of LC/HRMS datasets, exemplified on a green alga (C. reinhardtii) sample. Three-dimensional Kendrick mass plots have improved lipid class identification and fast spotting of falsely annotated lipid species. PMID- 29575336 TI - Simultaneously elevated FeNO and blood eosinophils relate to asthma morbidity in asthmatics from NHANES 2007-12. AB - BACKGROUND: Fraction of exhaled nitric oxide (FeNO) and blood eosinophil (B-Eos) count are biomarkers for type 2 inflammation. However, they signal different inflammatory pathways. Simultaneously elevated, they are related to more asthma events in a general population and among younger asthmatics. OBJECTIVE: To investigate if simultaneously elevated FeNO and B-Eos relate to asthma outcomes and lung function among subjects with asthma at a wide age span, and how different cut-offs for the markers affect these relations. METHOD: FeNO, B-Eos and forced expiratory volume in 1 second (FEV1 ) were assessed in 1419 subjects with asthma, aged 6-79 years old, from the National Health and Nutrition Examination Survey (NHANES) 2007-12. Elevated levels were defined as FeNO >=20 p.p.b. for children <12 years and >=25 p.p.b. for subjects >=12 years and B-Eos count >=300 cells/MUL. Additional analyses were performed for the cut-offs FeNO >35/30 and >50/35 p.p.b., and for B-Eos >=400 and >= 500 cells/MUL, as well as for different age subgroups (6-17, 18-44, >44 years old). Asthma events during the past year were self-reported. RESULTS: Subjects with simultaneously elevated FeNO and B-Eos compared with normal levels of both markers had a higher adjusted odds ratio (aOR (95%CI)) for having FEV1 <80% of predicted (2.15 (1.28-3.59), wheeze disturbing sleep (1.88 (1.27, 2.78)) but did not differ regarding asthma attacks past year. Elevated B-Eos, but not FeNO, was related to higher aOR for asthma attack (1.57 (1.14, 2.18) or emergency room (ER) visit due to asthma (1.88 (1.33, 2.64) when elevated FeNO and elevated B-Eos were studied as independent predictors. CONCLUSION: Simultaneously elevated FeNO and B-Eos related to reduced lung function in asthmatics, wheezing symptoms, but not to a history of asthma attacks. Asthma attacks and ER-visit due to asthma were related to increased B Eos levels. PMID- 29575334 TI - Hispidulin suppresses cell growth and metastasis by targeting PIM1 through JAK2/STAT3 signaling in colorectal cancer. AB - Colorectal cancer (CRC) accounts for over 600 000 deaths annually worldwide. The current study aims to evaluate the value of proto-oncogene PIM1 as a therapeutic target in CRC and investigate the anticancer activity of hispidulin, a naturally occurring phenolic flavonoid compound, against CRC. Immunohistochemistry analysis showed that PIM1 was upregulated in CRC tissue. The role of PIM1 as an oncogene was evidenced by the fact that PIM1 knockdown inhibits cell growth, induces apoptosis, and suppresses invasion. Our results showed that hispidulin exerts antitumor activity in CRC through inhibiting the expression of PIM1. Moreover, our findings revealed that hispidulin downregulated the expression of PIM1 by inhibiting JAK2/STAT3 signaling by generating reactive oxygen species. Furthermore, our in vivo studies showed that hispidulin can significantly inhibit tumor growth and metastasis in CRC. Collectively, our results provide an experimental basis for trialing hispidulin in CRC treatment. PIM1 can be considered a potential therapeutic target in CRC. PMID- 29575337 TI - Diurnal periodicity of assimilate transport shapes resource allocation and whole plant carbon balance. AB - Whole-plant carbon balance comprises diurnal fluctuations of photosynthetic carbon gain and respiratory losses, as well as partitioning of assimilates between phototrophic and heterotrophic organs. Because it is difficult to access, the root system is frequently neglected in growth models, or its metabolism is rated based on generalizations from other organs. Here, whole-plant cuvettes were used for investigating total-plant carbon exchange with the environment over full diurnal cycles. Dynamics of primary metabolism and diurnally resolved phloem exudation profiles, as proxy of assimilate transport, were combined to obtain a full picture of resource allocation. This uncovered a strong impact of periodicity of inter-organ transport on the efficiency of carbon gain. While a sinusoidal fluctuation of the transport rate, with minor diel deflections, minimized respiratory losses in Arabidopsis wild-type plants, triangular or rectangular patterns of transport, found in mutants defective in either starch or sucrose metabolism, increased root respiration at the end or beginning of the day, respectively. Power spectral density and cross-correlation analysis revealed that only the rate of starch synthesis was strictly correlated to the rate of net photosynthesis in wild-type, while in a sucrose-phosphate synthase mutant (spsa1), this applied also to carboxylate synthesis, serving as an alternative carbon pool. In the starchless mutant of plastidial phospho-gluco mutase (pgm), none of these rates, but concentrations of sucrose and glucose in the root, followed the pattern of photosynthesis, indicating direct transduction of shoot sugar levels to the root. The results demonstrate that starch metabolism alone is insufficient to buffer diurnal fluctuations of carbon exchange. PMID- 29575338 TI - Polymer-Brush-Grafted Mesoporous Silica Nanoparticles for Triggered Drug Delivery. AB - Mesoporous silica nanoparticles (MSNs) have been demonstrated to be one of the most promising drug-delivery systems (DDSs) to transport a variety of drugs/biomolecules. Functionalization of MSN surfaces with responsive polymer brushes leads to intelligent and controllable drug-delivery properties, that is, the encapsulated drugs/biomolecules will only be released upon certain stimuli including pH, temperature, light, enzyme, ultrasound, or redox, thus maximizing their therapeutic efficiency and minimizing side effects. These polymer brushes can also increase the stability and extend the release period of the loaded cargoes. This Minireview presents an overview of recent research progress on stimuli-responsive controlled DDSs based on polymer-brush-grafted MSNs. Utilizing the switching abilities of the grafted responsive polymer brushes, the smart DDSs show great potential for biomedical applications, especially for cancer therapy. PMID- 29575340 TI - Soil properties and sediment accretion modulate methane fluxes from restored wetlands. AB - Wetlands are the largest source of methane (CH4 ) globally, yet our understanding of how process-level controls scale to ecosystem fluxes remains limited. It is particularly uncertain how variable soil properties influence ecosystem CH4 emissions on annual time scales. We measured ecosystem carbon dioxide (CO2 ) and CH4 fluxes by eddy covariance from two wetlands recently restored on peat and alluvium soils within the Sacramento-San Joaquin Delta of California. Annual CH4 fluxes from the alluvium wetland were significantly lower than the peat site for multiple years following restoration, but these differences were not explained by variation in dominant climate drivers or productivity across wetlands. Soil iron (Fe) concentrations were significantly higher in alluvium soils, and alluvium CH4 fluxes were decoupled from plant processes compared with the peat site, as expected when Fe reduction inhibits CH4 production in the rhizosphere. Soil carbon content and CO2 uptake rates did not vary across wetlands and, thus, could also be ruled out as drivers of initial CH4 flux differences. Differences in wetland CH4 fluxes across soil types were transient; alluvium wetland fluxes were similar to peat wetland fluxes 3 years after restoration. Changing alluvium CH4 emissions with time could not be explained by an empirical model based on dominant CH4 flux biophysical drivers, suggesting that other factors, not measured by our eddy covariance towers, were responsible for these changes. Recently accreted alluvium soils were less acidic and contained more reduced Fe compared with the pre-restoration parent soils, suggesting that CH4 emissions increased as conditions became more favorable to methanogenesis within wetland sediments. This study suggests that alluvium soil properties, likely Fe content, are capable of inhibiting ecosystem-scale wetland CH4 flux, but these effects appear to be transient without continued input of alluvium to wetland sediments. PMID- 29575339 TI - Treatment response and non-response in CBT and Network Support for alcohol disorders: targeted mechanisms and common factors. AB - AIMS: To determine whether mechanisms of drinking behavior change that are targeted by specific treatments mediate the effects of Packaged Cognitive Behavior Therapy (PCBT) and Network Support (NS) on abstinence rates throughout 27 months. DESIGN: Secondary analysis of data from two Network Support Project randomized clinical trials, in which participants were assigned to either a case management control treatment (control) or NS treatment in trial 1, or to PCBT or NS treatment in trial 2. SETTING: An out-patient substance abuse treatment site at a university medical center in the United States. PARTICIPANTS: A total of 249 men and 154 women (n = 403) with alcohol use disorder. MEASUREMENTS: The primary outcome was membership in a treatment responder class determined by growth mixture modeling (GMM) of monthly proportion days abstinent (PDA) to 27 months. Key predictors of responder class membership included network change variables, and changes in coping scores and self-efficacy. FINDINGS: GMM analyses indicated that a three-class solution provided the best fit to the data: a treatment responder class comprising almost 55% of patients, a late relapsing class that showed post-treatment gains followed by a return to baseline drinking (12.7% of patients) and a non-responder class (32% of patients). Analyses indicated that treatment effects on responder class membership were moderated by baseline drinking (P < 0.001). PCBT effects were mediated by changes in coping scores (P < 0.05). NS treatment effects were also mediated by coping change, as well as by increases in self-efficacy and in number of abstinent friends (P < 0.05). CONCLUSIONS: Long-term success in Packaged Cognitive Behavior Therapy and Network Support treatments for alcohol use disorder appears to be mediated by both general mechanisms (developing coping skills and self-efficacy) and treatment targeted mechanisms (developing network strategies that emphasize social support and avoiding friends who drink).

PMID- 29575341 TI - Coexistence of gastrointestinal stromal tumor and leiomyosarcoma of the stomach presenting as a collision tumor: A case report and review of literature. AB - Collision tumor of the stomach is rare. We report a rare case of a gastric collision tumor consisting of gastrointestinal stromal tumors (GISTs) and leiomyosarcoma (LMS). Computed tomography scan revealed a 15 cm sized mass in the posterior wall of the body of the stomach. Gross examination of the wedge resection specimen showed the tumor located in the muscularis propria with extramural protrusion into the peritoneal cavity and the gastric cavity with geographic necrosis, hemorrhage, and mucosal ulceration. Histologically, the majority of the tumor consisted of the GIST component and the minor area in the submucosal region consisted of the LMS component. The tumor showed an abrupt transition between GIST and LMS by histologically and immunohistochemically, suggesting a collision tumor. Furthermore, the GIST components exhibited a c-kit exon 11 mutation. On the other hand, LMS component exhibited neither c-kit nor platelet-derived growth factor receptor-alpha (PDGFRA) mutation. Here we describe a case of the collision tumor consisting of GIST and LMS and its literature review.

PMID- 29575346 TI - The association between gait and physical fitness in adults with intellectual disabilities. AB - BACKGROUND: Gait deviations are often seen in adults with intellectual disabilities (ID). Their low physical fitness levels may be associated with these deviations. Understanding the impact of fitness on gait in this population is important for developing interventions to improve gait. In a cross-sectional study, we assessed the association between multiple physical fitness components and spatiotemporal gait parameters in adults with ID. METHOD: Gait characteristics of 31 adults (42.77 +/- 16.70 years) with ID without Down syndrome were assessed with the GAITRite at comfortable (CS) and fast speed (FS), along with fitness assessments (body composition, muscular endurance, strength, balance, Short Physical Performance Battery). RESULTS: At CS, adults with ID with higher BMI and/or waist circumference spent more time in double support. At FS, those with better muscular endurance took steps faster, those with better balance took bigger steps and strides and those with better Short Physical Performance Battery scores took bigger steps and strides at higher velocity. CONCLUSIONS: Body composition was mostly associated with gait at CS, while the other physical fitness components were mostly associated with gait at FS. Better fitness may therefore be more important in more challenging conditions. These insights are useful for developing interventions to improve gait in adults with ID. PMID- 29575345 TI - Risk factors for multidrug-resistant Gram-negative bacteria infection in intensive care units: A meta-analysis. AB - AIMS: To identify the risk factors for multidrug-resistant Gram-negative bacteria systematically and provide suggestions and an evidence-base for clinical measures. BACKGROUND: With the increase in the social population, changes in human behaviour and ecosystems, as well as economic development, bacteria have gradually produced drug resistance genes. These have swept through intensive care units causing high mortality. METHODS: Relevant literature which included case control and cohort studies published from January 1999 to March 2017 were searched in the Cochrane Library, PubMed, Web of Science, and Medline. Meta analysis was performed by using StataSE version 12.0 software. RESULTS: Eighteen studies of 235 publications were eligible. Male gender (OR 1.40, 95%CI 1.09, 1.80), having an operative procedure (OR 1.31, 95%CI 1.10, 1.56), a central venous catheter (OR 1.22, 95%CI 1.01, 1.48), mechanical ventilation (OR 1.25, 95%CI 1.07, 1.46), previous antibiotic therapy (OR 1.66, 95%CI 1.41, 1.96), length of ICU stay (weighted mean difference 8.18, 95%CI 0.27, 16.10), and types of health-associated infections were the identified risk factors for multidrug resistant Gram-negative bacterial infection in intensive care units; moreover, diabetes mellitus was not. CONCLUSION: Six risk factors were associated with multidrug-resistant Gram-negative bacterial infection in intensive care units. Antimicrobial stewardship, infection control, and medical staff prevention care are needed. PMID- 29575347 TI - Predictive power of food web models based on body size decreases with trophic complexity. AB - Food web models parameterised using body size show promise to predict trophic interaction strengths (IS) and abundance dynamics. However, this remains to be rigorously tested in food webs beyond simple trophic modules, where indirect and intraguild interactions could be important and driven by traits other than body size. We systematically varied predator body size, guild composition and richness in microcosm insect webs and compared experimental outcomes with predictions of IS from models with allometrically scaled parameters. Body size was a strong predictor of IS in simple modules (r2 = 0.92), but with increasing complexity the predictive power decreased, with model IS being consistently overestimated. We quantify the strength of observed trophic interaction modifications, partition this into density-mediated vs. behaviour-mediated indirect effects and show that model shortcomings in predicting IS is related to the size of behaviour-mediated effects. Our findings encourage development of dynamical food web models explicitly including and exploring indirect mechanisms. PMID- 29575349 TI - Rapid divergence of mussel populations despite incomplete barriers to dispersal. AB - Striking genetic structure among marine populations at small spatial scales is becoming evident with extensive molecular studies. Such observations suggest isolation at small scales may play an important role in forming patterns of genetic diversity within species. Isolation-by-distance, isolation-by-environment and historical priority effects are umbrella terms for a suite of processes that underlie genetic structure, but their relative importance at different spatial and temporal scales remains elusive. Here, we use marine lakes in Indonesia to assess genetic structure and assess the relative roles of the processes in shaping genetic differentiation in populations of a bivalve mussel (Brachidontes sp.). Marine lakes are landlocked waterbodies of similar age (6,000-10,000 years), but with heterogeneous environments and varying degrees of connection to the sea. Using a population genomic approach (double-digest restriction-site associated DNA sequencing), we show strong genetic structuring across populations (range FST : 0.07-0.24) and find limited gene flow through admixture plots. At large spatial scales (>1,400 km), a clear isolation-by-distance pattern was detected. At smaller spatial scales (<200 km), this pattern is maintained, but accompanied by an association of genetic divergence with degree of connection. We hypothesize that (incomplete) dispersal barriers can cause initial isolation, allowing priority effects to give the numerical advantage necessary to initiate strong genetic structure. Priority effects may be strengthened by local adaptation, which the data may corroborate by showing a high correlation between mussel genotypes and temperature. Our study indicates an often-neglected role of (evolution-mediated) priority effects in shaping population divergence. PMID- 29575350 TI - Regulatory T cells in autoimmune skin diseases. AB - CD4+ Foxp3+ regulatory T cells (Tregs) are suppressors of immune activation and play a crucial role in the maintenance of peripheral tolerance. Mutations of Foxp3 result in fatal autoimmunity in multiple organs, including the skin, in both humans and mice. Many studies have demonstrated the altered frequency and functions of Tregs, changes in cytokine and chemokine levels related to Tregs and the differences in genetic background regarding Tregs in autoimmune skin disorders. Recent studies have extended our knowledge of certain properties of Tregs, especially skin-resident Tregs. In addition, some novel therapies have been performed by modulating the number and the function of Tregs. This review focuses on the role of Tregs in some autoimmune skin disorders, including alopecia areata, vitiligo, pemphigoid and pemphigus, and systemic sclerosis, and discusses questions that remain to be addressed. PMID- 29575348 TI - The tempo of human childhood: a maternal foot on the accelerator, a paternal foot on the brake. AB - Relative to the life history of other great apes, that of humans is characterized by early weaning and short interbirth intervals (IBIs). We propose that in modern humans, birth until adrenarche, or the rise in adrenal androgens, developmentally corresponds to the period from birth until weaning in great apes and ancestral hominins. According to this hypothesis, humans achieved short IBIs by subdividing ancestral infancy into a nurseling phase, during which offspring fed at the breast, and a weanling phase, during which offspring fed specially prepared foods. Imprinted genes influence the timing of human weaning and adrenarche, with paternally expressed genes promoting delays in childhood maturation and maternally expressed genes promoting accelerated maturation. These observations suggest that the tempo of human development has been shaped by consequences for the fitness of kin, with faster development increasing maternal fitness at a cost to child fitness. The effects of imprinted genes suggest that the duration of the juvenile period (adrenarche until puberty) has also been shaped by evolutionary conflicts within the family. PMID- 29575351 TI - Measuring the impact of pharmacoepidemiologic research using altmetrics: A case study of a CNODES drug-safety article. AB - PURPOSE: To provide an overview of altmetrics, including their potential benefits and limitations, how they may be obtained, and their role in assessing pharmacoepidemiologic research impact. METHODS: Our review was informed by compiling relevant literature identified through searching multiple health research databases (PubMed, Embase, and CIHNAHL) and grey literature sources (websites, blogs, and reports). We demonstrate how pharmacoepidemiologists, in particular, may use altmetrics to understand scholarly impact and knowledge translation by providing a case study of a drug-safety study conducted by the Canadian Network of Observational Drug Effect Studies. RESULTS: A common approach to measuring research impact is the use of citation-based metrics, such as an article's citation count or a journal's impact factor. "Alternative" metrics, or altmetrics, are increasingly supported as a complementary measure of research uptake in the age of social media. Altmetrics are nontraditional indicators that capture a diverse set of traceable, online research-related artifacts including peer-reviewed publications and other research outputs (software, datasets, blogs, videos, posters, policy documents, presentations, social media posts, wiki entries, etc). CONCLUSION: Compared with traditional citation-based metrics, altmetrics take a more holistic view of research impact, attempting to capture the activity and engagement of both scholarly and nonscholarly communities. Despite the limited theoretical underpinnings, possible commercial influence, potential for gaming and manipulation, and numerous data quality-related issues, altmetrics are promising as a supplement to more traditional citation-based metrics because they can ingest and process a larger set of data points related to the flow and reach of scholarly communication from an expanded pool of stakeholders. Unlike citation-based metrics, altmetrics are not inherently rooted in the research publication process, which includes peer review; it is unclear to what extent they should be used for research evaluation. PMID- 29575352 TI - Heart rate variability characteristics of patients with irritable bowel syndrome and associations with symptoms. AB - BACKGROUND: Disturbed brain-gut interactions are assumed to be of importance for symptom generation in patients with irritable bowel syndrome (IBS). The autonomic nervous system (ANS) is part of the bidirectional brain-gut communication, but previous studies in IBS show diverging results. We aimed to identify subgroups of IBS patients with distinct ANS characteristics differentiating them from healthy controls (HC), and to study associations between ANS status and symptoms. METHODS: Heart rate variability (HRV) was measured in IBS patients and HC (Holter monitoring: supine and standing positions with controlled respiration and ambulatory 24-hour period). Frequency (5 minutes, supine, standing) and time domains (24 hours, day, night) were analyzed. Validated questionnaires were used to measure gastrointestinal and psychological symptoms in patients. Patients and HC were compared on a univariate and multivariate level (principal component analysis [PCA] and orthogonal partial least squares discriminatory analysis (OPLS DA)). KEY RESULTS: We analyzed 158 IBS patients (Rome III) and 39 HC. Patients differed significantly from HC in HRV parameters during daytime and in standing position. In the PCA, a majority of patients overlapped with HC, but the weighted means differed (P < .01). A subset of patients (n = 30; 19%) with an aberrant global HRV profile was identified through PCA and OPLS-DA; these patients reported more severe symptoms of frequent (P < .05) and loose stools (P = .03), as well as urgency (P = .01). CONCLUSIONS AND INFERENCES: Altered ANS function was demonstrated in patients with IBS, and this might be of particular relevance for symptoms in a subset of the patients. PMID- 29575353 TI - Scale and direction of adaptive introgression between black cottonwood (Populus trichocarpa) and balsam poplar (P. balsamifera). AB - Introgression can introduce novel genetic variation at a faster rate than mutation alone and result in adaptive introgression when adaptive alleles are maintained in the recipient genome over time by natural selection. A previous study from our group demonstrated adaptive introgression from Populus balsamifera into P. trichocarpa in a target genomic region. Here we expand our local ancestry analysis to the whole genome of both parents to provide a comprehensive view of introgression patterns and to identify additional candidate regions for adaptive introgression genomewide. Populus trichocarpa is a large, fast-growing tree of mild coastal regions of the Pacific Northwest, whereas P. balsamifera is a smaller stature tree of continental and boreal regions with intense winter cold. The species hybridize where they are parapatric. We detected asymmetric patterns of introgression across the whole genome of these two poplar species adapted to contrasting environments, with stronger introgression from P. balsamifera to P. trichocarpa than vice versa. Admixed P. trichocarpa individuals contained more genomic regions with unusually high levels of introgression (19 regions) and also the largest introgressed genome fragment (1.02 Mb) compared with admixed P. balsamifera (nine regions). Our analysis also revealed numerous candidate regions for adaptive introgression with strong signals of selection, notably related to disease resistance, and enriched for genes that may play crucial roles in survival and adaptation. Furthermore, we detected a potential overrepresentation of subtelomeric regions in P. balsamifera introgressed into P. trichocarpa and possible protection of sex-determining regions from interspecific gene flow. PMID- 29575354 TI - Prolonged T-wave peak-end interval in Down syndrome patients with congenitally normal hearts. AB - BACKGROUND: Heterogeneity of ventricular repolarization has been assessed using the QT dispersion in Down syndrome (DS) patients with congenitally normal hearts. Novel repolarization indexes, that is, T-wave peak-end (Tp-e) interval and Tp e/QT ratio, however, have not previously been evaluated in these patients. The aim of this study was therefore to evaluate the Tp-e interval and Tp-e/QT ratio in DS patients without congenital heart defects. METHODS: Tp-e interval, Tp-e dispersion, and Tp-e/QT ratio were compared between 160 DS patients and 110 age- and sex-matched healthy controls on 12-lead surface electrocardiogram. RESULTS: Heart rate, Tp-e interval, Tp-e dispersion, Tp-e/QT and Tp-e/QTc ratios were significantly higher in the DS group than the control group. CONCLUSION: Myocardial repolarization indexes in DS patients with congenitally normal hearts were found to be prolonged compared with those in normal controls. Further evaluation is warranted to elucidate the relationship between prolonged repolarization indexes and arrhythmic events in these patients. PMID- 29575355 TI - Family aggregation of language impairment in an isolated Chilean population from Robinson Crusoe Island. AB - BACKGROUND: It has been reported that the inhabitants of the Chilean Robinson Crusoe Island have an increased frequency of specific language impairment (SLI) or developmental language disorder (DLD). AIMS: To explore the familial aggregation of DLD in this community. METHODS & PROCEDURES: We assessed the frequency of DLD amongst colonial children between the ages of 3 and 8;11 years (50 individuals from 45 nuclear families). Familial aggregation rates of language disorder were calculated by assessing all available first-degree relatives (n = 107, 77 parents, 25 siblings, five half-siblings) of the probands. OUTCOMES & RESULTS: We found that 71% of the child population performed significantly below expected in measures of phonological production or expressive and receptive morphology. The majority of these children presented with severe expressive and/or receptive language difficulties. One-quarter of language-disordered probands primarily had phonological difficulties. Family members of affected probands experienced a higher risk of language disorder than those of typically developing probands. This increased risk was apparent regardless of non-verbal IQ. CONCLUSIONS & IMPLICATIONS: The study substantiates the existence of a familial form of speech and language disorder on Robinson Crusoe Island. Furthermore, we find that the familiarity is stable regardless of non-verbal IQ, supporting the recent movement to reduce the importance of non-verbal IQ criterion in DLD diagnoses. PMID- 29575356 TI - Emerging threat of the 21st century lightscape to global biodiversity. AB - Over the last century the temporal and spatial distribution of light on Earth has been drastically altered by human activity. Despite mounting evidence of detrimental effects of light pollution on organisms and their trophic interactions, the extent to which light pollution threatens biodiversity on a global scale remains unclear. We assessed the spatial extent and magnitude of light encroachment by measuring change in the extent of light using satellite imagery from 1992 to 2012 relative to species richness for terrestrial and freshwater mammals, birds, reptiles, and amphibians. The encroachment of light into previously dark areas was consistently high, often doubling, in areas of high species richness for all four groups. This pattern persisted for nocturnal groups (e.g., bats, owls, and geckos) and species considered vulnerable to extinction. Areas with high species richness and large increases in light extent were clustered within newly industrialized regions where expansion of light is likely to continue unabated unless we act to conserve remaining darkness. Implementing change at a global scale requires global public, and therefore scientific, support. Here, we offer substantial evidence that light extent is increasing where biodiversity is high, representing an emerging threat to global biodiversity requiring immediate attention. PMID- 29575357 TI - RASopathic comedo-like or cystic lesions induced by Vemurafenib: A model of skin lesions similar but not identical to those induced by dioxins (MADISH). AB - BACKGROUND: Patients treated with vemurafenib for metastatic melanoma often develop skin lesions similar to those observed after exposure to dioxin-like compounds. We previously called these lesions MADISH (metabolizing acquired dioxin-induced skin hamartoma) when analysing a case of acute dioxin poisoning. OBJECTIVE: We performed a clinical trial aimed at comparing the skin lesions observed under vemurafenib treatment with MADISH in order to bring to light a possible cross-talk between vemurafenib and dioxin pathways. METHODS: In this case-series study we explored the histological aspect of skin lesions in 10 cases treated with vemurafenib for malignant melanoma. We also analysed the ability of vemurafenib and tyrosine kinase inhibitors to induce dioxin-AhR pathway. RESULTS: All patients had skin lesions diagnosed as "non-inflammatory acneiform eruption" by dermatologists. These were predominantly facial with notable retro-auricular involvement and clinically compatible with chloracne/MADISH when assessed by dioxin expert. Histological analysis showed mostly comedo-like lesions and dermal cysts containing epithelial wall with basal or lateral epithelial projections and lamellar keratinization, and alterations of remaining sebaceous glands. The expression of CYP1A1, a gene highly induced following dioxin exposure, was not observed in these lesions. Vemurafenib and the tyrosine kinase inhibitors erlotinib and gefitinib did not induce CYP1A1 activity. DISCUSSION: Although the skin lesions under vemurafenib treatment were morphologically similar to MADISH, the absence of CYP1A1 expression in dermal cysts of patients and the absence of CYP1A1 activation by vemurafenib led us consider that these skin lesions were different from true MADISH and not mediated by a cross-talk of AhR signalling, but rather to a hyperactivation of PI3K-Akt pathway as a consequence of vemurafenib treatment. A strong expression of CYP1A1 in the epithelial wall of dermal cysts must be required, parallel to the morphology of the lesions, to make the diagnosis of MADISH, the hallmark of an exposure to dioxin-like/chloracnegen compounds.

PMID- 29575359 TI - A retrospective histopathological, immunohistochemical and molecular study of the presence of Leishmania spp. in the skin of cats with head and neck ulcerative dermatitis. AB - BACKGROUND: Head and neck ulcers in cats can arise from allergic and nonallergic disorders, including feline leishmaniosis (FeL). It is important to rule out this aetiological agent in regions that are endemic for canine leishmaniosis, because the drugs used to treat immune-mediated disorders of cats can be contraindicated in the setting of infection. HYPOTHESIS/OBJECTIVES: The aim of this study was to evaluate the skin of cats with ulcerative dermatitis of the head or neck for evidence of Leishmania infection using combined immunohistochemistry (IHC) and Polymerase Chain Reaction (PCR). An IHC for tissue histiocytes was also utilized because leishmaniosis may provoke a histiocytic inflammatory response. ANIMALS: Twenty seven cats with head and/or neck ulcers. METHODS: Skin biopsy specimens were examined for the presence of Leishmania spp. by routine histopathological evaluation and IHC using a polyclonal anti-Leishmania antibody, and by quantitative PCR (qPCR). The ionized calcium-binding adapter molecule-1 (IBA-1) antibody was used to immunolocalize histiocytes. Selected history and clinical data were recorded. RESULTS: All specimens showed a superficial mid-perivascular mixed inflammatory infiltrate. The presence of histiocytes was confirmed in 23 of 27 cases with the IBA-1 antibody. Immunohistochemistry and qPCR techniques confirmed the absence of Leishmania in all cases. CONCLUSIONS AND CLINICAL IMPORTANCE: Leishmania did not seem to play a role in the pathogenesis of feline ulcerative dermatitis of the head and neck in the subjects studied, despite a lifestyle potentially associated with infection. Histiocytic infiltration of tissue is not a specific marker for Leishmania infection in this population.

AB - BACKGROUND: Acute kidney injury (AKI) is common in dogs, but evidence of efficacy of its treatment is lacking. OBJECTIVE: To evaluate the efficacy of fenoldopam in the management of AKI. ANIMALS: Forty dogs with naturally occurring heatstroke. METHODS: Dogs were prospectively enrolled and divided into treatment and the placebo groups (fenoldopam, constant rate infusion [CRI] of 0.1 ug/kg/min or saline, respectively). Urine production (UP) was measured using a closed system. Urinary clearances were performed at 4, 12, and 24 hours after presentation to estimate the effect of fenoldopam on UP, glomerular filtration rate (GFR) and sodium fractional excretion (NaFE). RESULTS: At presentation, severity of heatstroke, based on a previously developed scoring system, was similar between the study groups, but was significantly worse in nonsurvivors compared with survivors. Fenoldopam administration was not associated with hypotension. Overt AKI was diagnosed, based on the International Renal Interest Society guidelines in 22/40 (55%) of the dogs. Overall, 14/40 dogs (35%) died, with no significant (P = .507) mortality rate difference between the fenoldopam (6/20 dogs; 30%) and placebo (8/20; 40%) groups. The proportion of dogs with AKI did not differ between the fenoldopam and the placebo groups (9/20; 45% versus 13/20; 65%, respectively; P = .204). There were no differences in UP, GFR, and NaFE between the fenoldopam and the placebo groups. CONCLUSION AND CLINICAL IMPORTANCE: Fenoldopam CRI at 0.1 ug/kg/min did not have a clinically relevant effect on kidney function parameters in dogs with severe heatstroke-associated AKI.

AB - Chronic osteomyelitis is primarily caused by infection with Staphylococcus aureus (S. aureus). Antibiotics are commonly administered; however, it is a challenge to promote bone healing. The aim of this study was to investigate the in vitro effects of alkaloids from the herbal remedy Sophora flavescens (ASF) on rat calvarial osteoblasts (ROBs) infected with S. aureus and healthy osteoclasts. Cell proliferation and alkaline phosphatase, interleukin-6, and tumour necrosis factor-alpha activity was measured in infected ROBs; tartrate-resistant acid phosphatase was evaluated in osteoclasts via enzyme-linked immunosorbent assay. The mRNA and protein expression levels of bone morphogenetic protein 2, runt related transcription factor 2, osteoprotegerin, and receptor activator of nuclear factor kappa-B ligand were assessed in infected ROBs through reverse transcription-polymerase chain reaction and western blotting analysis, respectively. Results indicated that ASF increased the viability of uninfected ROBs and infected ROBs treated with vancomycin via regulation of bone morphogenetic protein 2, runt-related transcription factor, osteoprotegerin, and receptor activator of nuclear factor kappa-B ligand mRNA and protein expression levels. In addition, the secretion of the inflammatory factor tumour necrosis factor-alpha was decreased and alkaline phosphatase activity was increased, inhibiting the viability of osteoclasts and tartrate-resistant acid phosphatase activity. Therefore, the herbal remedy ASF has potential as a new treatment for chronic osteomyelitis. PMID- 29575362 TI - IgLON5 antibodies are infrequent in patients with isolated sleep apnea.

AB - Systematists and taxonomists have benefited greatly from the emergence of molecular methods. Species identification has become straightforward through DNA barcoding and the rapid build-up of massive DNA barcode reference libraries. In animals, mitonuclear discordance can significantly complicate the process of species identification and delimitation. The causes of mitonuclear discordance are either biological (e.g., introgression, incomplete lineage sorting, horizontal gene transfer androgenesis) or induced by operational factors (e.g., human error with specimen misidentification or incorrect species delimitation). Moreover, endosymbionts may play an important role in promoting fixation of mitochondrial genomes. Here, we study the mitonuclear discordance of wolf spiders species (Lycosidae) (independent cases from Alopecosa aculeata and Pardosa pullata groups) that share identical COI DNA barcodes. We approached the case utilizing double-digest restriction site-associated DNA sequencing (ddRADseq) to obtain and analyse genomic-scale data. Our results suggest that the observed cases of mitonuclear discordance are not due to operational reasons but result from biological processes. Further analysis indicated introgression and that incomplete lineage sorting is unlikely to have been responsible for the observed discrepancy. Additional survey of endosymbionts provided ideas on further research and their role in shaping mitochondrial DNA distribution patterns. Thus, ddRADseq grants an efficient way to study the taxonomy of problematic groups with insight into underlying evolutionary processes.

PMID- 29575369 TI - Drink Less Enjoy More: effects of a multi-component intervention on improving adherence to, and knowledge of, alcohol legislation in a UK nightlife setting. AB - AIMS: To estimate the association between implementation of a community-based multi-component intervention (Drink Less Enjoy More) and sales of alcohol to pseudo-intoxicated patrons and nightlife patron awareness of associated legislation. DESIGN: Cross-sectional pre-intervention and follow-up measurements, including alcohol test purchases (using pseudo-intoxicated patrons) in licensed premises (stratified random sample; 2013, 2015) and a survey with nightlife patrons (convenience sample; 2014, 2015). SETTING: One UK municipality with a large night-time economy. PARTICIPANTS: Licensed premises (pre = 73; follow-up = 100); nightlife patrons (pre = 214; follow-up = 202). INTERVENTION: The Drink Less Enjoy More intervention included three interacting components: community mobilization and awareness-raising; responsible bar server training; and active law enforcement of existing legislation prohibiting sales of alcohol to, and purchasing of alcohol for, a person who appears to be alcohol intoxicated: 'intoxicated', herein for economy. MEASUREMENTS: The primary outcomes were alcohol service refusal to pseudo-intoxicated patrons and nightlife patron knowledge of alcohol legislation (illegal to sell alcohol to, and purchase alcohol for, intoxicated people), adjusted for potential confounders including characteristics of the area, venue, test purchase and nightlife patron. FINDINGS: Pre-intervention, 16.4% of alcohol sales were refused, compared with 74.0% at follow-up (P < 0.001). In adjusted analyses, the odds of service refusal were higher at follow-up [adjusted odds ratio (aOR) = 14.63, P < 0.001]. Service refusal was also associated with server gender and patron drunkenness within the venue. Among drinkers, accurate awareness of alcohol legislation was higher at follow-up (sales: pre = 44.5%; follow-up = 66.0%; P < 0.001/purchase: pre = 32.5%; follow-up = 56.0%; P < 0.001). In adjusted analyses, knowledge of legislation was higher at follow-up (sales: aOR = 2.73, P < 0.001; purchasing: aOR = 2.73, P < 0.001). Knowledge of legislation was also associated with participant age (purchasing) and expectations of intoxication (sales). CONCLUSION: A community-based multi-component intervention concerning alcohol sales legislation in the United Kingdom (UK) was associated with a reduction in sales of alcohol to pseudo-intoxicated patrons in on-licensed premises in a UK nightlife setting and an improvement in nightlife patron awareness of associated legislation. PMID- 29575368 TI - MicroRNA-708-3p mediates metastasis and chemoresistance through inhibition of epithelial-to-mesenchymal transition in breast cancer. AB - Metastasis and chemoresistance remain major challenges in the clinical treatment of breast cancer. Recent studies show that dysregulated microRNAs (miRNAs) play an important role in metastasis and chemoresistance development in breast cancer. Herein, we identified downregulated expression of miR-708-3p in breast cancers. In particular, miR-708-3p expression was significantly decreased in specimens from breast cancer patients with metastasis compared to that in specimens from patients with no metastasis. Consistent with clinical data, our in vitro data show that miR-708-3p was more significantly decreased in invasive breast cancer cell lines. In addition, our data show that inhibition of miR-708-3p significantly stimulated breast cancer cell metastasis and induced chemoresistance both in vitro and in vivo. In contrast, overexpression of miR-708 3p dramatically inhibited breast cancer cell metastasis and enhanced the sensitivity of breast cancer cells to chemotherapy both in vitro and in vivo. Furthermore, we identified that miR-708-3p inhibits breast cancer cell epithelial to-mesenchymal transition (EMT) by directly targeting EMT activators, including ZEB1, CDH2 and vimentin. Taken together, our findings suggest that miR-708-3p acts as a cancer suppressor miRNA and carries out its anticancer function by inhibiting EMT in breast cancer. In addition, our findings suggest that restoration of miR-708-3p may be a novel strategy for inhibiting breast cancer metastasis and overcoming the chemoresistance of breast cancer cells. PMID- 29575370 TI - Atomic Iridium Incorporated in Cobalt Hydroxide for Efficient Oxygen Evolution Catalysis in Neutral Electrolyte. AB - Developing highly efficient catalysts for oxygen evolution reaction (OER) in neutral media is extremely crucial for microbial electrolysis cells and electrochemical CO2 reduction. Herein, a facile one-step approach is developed to synthesize a new type of well-dispersed iridium (Ir) incorporated cobalt-based hydroxide nanosheets (nominated as CoIr) for OER. The Ir species as clusters and single atoms are incorporated into the defect-rich hydroxide nanosheets through the formation of rich Co-Ir species, as revealed by systematic synchrotron radiation based X-ray spectroscopic characterizations combining with high-angle annular dark-field scanning transmission electron microscopy measurement. The optimized CoIr with 9.7 wt% Ir content displays highly efficient OER catalytic performance with an overpotential of 373 mV to achieve the current density of 10 mA cm-2 in 1.0 m phosphate buffer solution, significantly outperforming the commercial IrO2 catalysts. Further characterizations toward the catalyst after undergoing OER process indicate that unique Co oxyhydroxide and high valence Ir species with low-coordination structure are formed due to the high oxidation potentials, which authentically contributes to superior OER performance. This work not only provides a state-of-the-art OER catalyst in neutral media but also unravels the root of the excellent performance based on efficient structural identifications. PMID- 29575371 TI - Practical guide to dynamic pelvic floor MRI. AB - : Pelvic floor dysfunction encompasses a spectrum of functional disorders that result from impairment of the ligaments, fasciae, and muscles supporting the pelvic organs. It is a prevalent disorder that carries a lifetime risk over 10% for undergoing a surgical repair. Pelvic floor weakness presents as a wide range of symptoms, including pain, pelvic pressure or bulging, urinary and fecal incontinence, constipation, and sexual dysfunction. A correct diagnosis by clinical examination alone can be challenging, particularly in cases involving multiple compartments. Magnetic resonance imaging (MRI) allows noninvasive, radiation-free, high soft-tissue resolution evaluation of all three pelvic compartments, and has proved a reliable technique for accurate diagnosis of pelvic floor dysfunction. MR defecography with steady-state sequences allows detailed anatomic and functional evaluation of the pelvic floor. This article provides an overview of normal anatomy and function of the pelvic floor and discusses a practical approach to the evaluation of imaging findings of pelvic floor relaxation, pelvic organ prolapse, fecal incontinence, and obstructed defecation.

PMID- 29575372 TI - Radar plots: A novel modality for displaying disparate data on the efficacy of eluxadoline for the treatment of irritable bowel syndrome with diarrhea. AB - BACKGROUND: Patients with irritable bowel syndrome with diarrhea (IBS-D) experience a range of abdominal and bowel symptoms; successful management requires alleviation of this constellation of symptoms. Eluxadoline, a locally active mixed MU- and kappa-opioid receptor agonist and delta-opioid receptor antagonist, is approved for the treatment of IBS-D in adults based on the results of 2 Phase 3 studies. Radar plots can facilitate comprehensive, visual evaluation of diverse but interrelated efficacy endpoints. METHODS: Two double-blind, placebo-controlled, Phase 3 trials (IBS-3001 and IBS-3002) randomized patients meeting Rome III criteria for IBS-D to twice-daily eluxadoline 75 or 100 mg or placebo. Radar plots were prepared showing pooled Weeks 1-26 response rates for the primary efficacy composite endpoint (simultaneous improvement in abdominal pain and stool consistency), stool consistency, abdominal pain, urgency-free days, and adequate relief, and change from baseline to Week 26 in IBS-D global symptom score, abdominal discomfort, abdominal pain, abdominal bloating, and daily number of bowel movements. KEY RESULTS: The studies enrolled 2428 patients. Eluxadoline increased Weeks 1-26 responder proportions vs placebo for the composite endpoint, stool consistency, abdominal pain, urgency-free days, and adequate relief. Changes from baseline to Week 26 in IBS-D global symptom score, abdominal discomfort, abdominal pain, abdominal bloating, and number of bowel movements were greater with eluxadoline vs placebo. CONCLUSIONS AND INFERENCES: Data presentation in radar plot format facilitates interpretation across multiple domains, demonstrating that eluxadoline treatment led to improvements vs placebo across 13 endpoints representing the range of symptoms experienced by patients with IBS-D.

PMID- 29575373 TI - The anatomical components of the cardiac outflow tract of chondrichthyans and actinopterygians. AB - The outflow tract of the fish heart is the segment interposed between the ventricle and the ventral aorta. It holds the valves that prevent blood backflow from the gill vasculature to the ventricle. The anatomical composition, histological structure and evolutionary changes in the fish cardiac outflow tract have been under discussion for nearly two centuries and are still subject to debate. This paper offers a brief historical review of the main conceptions about the cardiac outflow tract components of chondrichthyans (cartilaginous fish) and actinopterygians (ray-finned fish) which have been put forward since the beginning of the nineteenth century up to the current day. We focus on the evolutionary origin of the outflow tract components and the changes to which they have been subject in the major extant groups of chondrichthyans and actinopterygians. In addition, an attempt is made to infer the primitive anatomical design of the heart of the gnathostomes (jawed vertebrates). Finally, several areas of further investigation are suggested. Recent work on fish heart morphology has shown that the cardiac outflow tract of chondrichthyans does not consist exclusively of the myocardial conus arteriosus as classically thought. A conus arteriosus and a bulbus arteriosus, devoid of myocardium and mainly composed of elastin and smooth muscle, are usually present in cartilaginous and ray-finned fish. This is consistent with the suggestion that both components coexisted from the onset of the gnathostome radiation. There is evidence that the conus arteriosus appeared in the agnathans. By contrast, the evolutionary origin of the bulbus is still unclear. It is almost certain that in all fish, both the conus and bulbus develop from the embryonic second heart field. We suggest herein that the primitive anatomical heart of the jawed vertebrates consisted of a sinus venosus containing the pacemaker tissue, an atrium possessing trabeculated myocardium, an atrioventricular region with compact myocardium which supported the atrioventricular valves, a ventricle composed of mixed myocardium, and an outflow tract consisting of a conus arteriosus, with compact myocardium in its wall and valves at its luminal side, and a non-myocardial bulbus arteriosus that connected the conus with the ventral aorta. Chondrichthyans have retained this basic anatomical design of the heart. In actinopterygians, the heart has been subject to notable changes during evolution. Among them, the following two should be highlighted: (i) a decrease in size of the conus in combination with a remarkable development of the bulbus, especially in teleosts; and (ii) loss of the myocardial compact layer of the ventricle in many teleost species. PMID- 29575375 TI - A re-examination of the BIS/BAS scales: Evidence for BIS and BAS as unidimensional scales. AB - OBJECTIVES: Carver and White's behavioral inhibition system and behavioral activation system (BIS/BAS) scales are the most widely used to assess constructs of the revised reinforcement sensitivity theory. This study provides a re examination of the latent structure of the original BIS/BAS scales. METHODS: The interpretability of the three purported BAS subfactors relative to a "general behavioral activation" factor was assessed using Schmid-Leiman and standard confirmatory factor analysis. Regarding the BIS scale, comparisons were made between (a) Carver and White's unidimensional BIS model, (b) Johnson, Turner, and Iwata's 2-factor BIS model, (c) Heym, Ferguson, and Lawrence's alternative 2 factor BIS model, and (d) a modified Heym et al. model (unidimensional) controlling for method effects of reverse-scored items. RESULTS: Results revealed the majority of variance of individual BAS items was accounted for by a common, general BAS dimension. Additionally, for the BIS scale, results of the chi2 difference statistical test supporting the 1-factor model, as well as the noted theoretical and psychometric difficulties in interpreting a multifactor BIS scale, provide converging support that BIS items actually represent a single, unidimensional factor. CONCLUSIONS: The collective results suggested that the BIS and BAS scales should be conceptualized as separate unidimensional measures, which is consistent with theory behind the original development. PMID- 29575376 TI - Incomplete Hippocampal Inversion and Its Relationship to Hippocampal Subfield Volumes and Aging. AB - BACKGROUND AND PURPOSE: Incomplete hippocampal inversion (IHI) is an atypical anatomical pattern presented by the hippocampus. It is associated with several neuropathological conditions and is thought to be a factor of susceptibility to hippocampal sclerosis and loss of volume. The volume loss of hippocampus is an inevitable consequence of aging, and when accelerated it is commonly considered an imaging biomarker of Alzheimer's disease dementia. METHODS: We have studied the relationship between IHI and hippocampal subfield volumes in a cohort of 60 healthy participants of 49-87 years of age. The presence and severity of IHI and hippocampal subfield volumes were quantified from T2 magnetic resonance (MR) images acquired at 3T. RESULTS: It was found that IHI presented in 23.3% of participants. Right unilateral IHI was rare (two cases, 3.3%) in comparison to left unilateral IHI (nine cases, 15%), with three (5%) of participants showing bilateral IHI. No significant relationships between the whole hippocampal volumes and IHI were observed. Instead, significant relationships between the volumes of the left and right cornu ammonis subfield-1 (CA1) and IHI scores were evident. CONCLUSIONS: The rates of IHI prevalence in the current cohort are similar to those previously reported in healthy cohorts. The IHI severity is related to hippocampal subfield volumes, most notably the CA1, which is a novel finding with potential implications in research on aging and dementia. PMID- 29575377 TI - Site-Selective Cysteine-Cyclooctyne Conjugation. AB - We report a site-selective cysteine-cyclooctyne conjugation reaction between a seven-residue peptide tag (DBCO-tag, Leu-Cys-Tyr-Pro-Trp-Val-Tyr) at the N or C terminus of a peptide or protein and various aza-dibenzocyclooctyne (DBCO) reagents. Compared to a cysteine peptide control, the DBCO-tag increases the rate of the thiol-yne reaction 220-fold, thereby enabling selective conjugation of DBCO-tag to DBCO-linked fluorescent probes, affinity tags, and cytotoxic drug molecules. Fusion of DBCO-tag with the protein of interest enables regioselective cysteine modification on proteins that contain multiple endogenous cysteines; these examples include green fluorescent protein and the antibody trastuzumab. This study demonstrates that short peptide tags can aid in accelerating bond forming reactions that are often slow to non-existent in water. PMID- 29575378 TI - Recent use of medical infrared thermography in skin neoplasms. AB - BACKGROUND: Infrared thermal imaging captures the infrared radiation emitted by the skin surface. The thermograms contain valuable information, since the temperature distribution can be used to characterize physiological anomalies. Thus, the use of infrared thermal imaging (IRT) has been studied as a possible medical tool to aid in the diagnosis of skin oncological lesions. The aim of this review is to assess the current state of the applications of IRT in skin neoplasm identification and characterization. METHODS: A literature survey was conducted using the reference bibliographic databases: Scopus, PubMed and ISI Web of Science. Keywords (thermography, infrared imaging, thermal imaging and skin cancer) were combined and its presence was verified at the title and abstract of the article or as a main topic. Only articles published after 2013 were considered during this search. RESULTS: In total, 55 articles were encountered, resulting in 14 publications for revision after applying the exclusion criteria. It was denoted that IRT have been used to characterize and distinguish between malignant and benign neoplasms and different skin cancer types. IRT has also been successfully applied in the treatment evaluation of these types of lesions. CONCLUSION: Trends and future challenges have been established to improve the application of IRT in this field, disclosing that dynamic thermography is a promising tool for early identification of oncological skin conditions. PMID- 29575380 TI - Polyelectrolyte-Graphene Oxide Multilayer Composites for Array of Microchambers which are Mechanically Robust and Responsive to NIR Light. AB - Development of composite polymer/graphene oxide (GO) materials attracts significant attention due to their unique properties. In this work, highly ordered arrays of hollow microchambers made of composite polyelectrolyte/GO multilayers (PEGOMs) are successfully fabricated via layer-by-layer assembly on sacrificial or sustainable templates having imprinted patterns of microwells on their surface. Mechanical and optical properties of PEGOMs are studied by nanoindentation and near-infrared (NIR) absorption spectroscopy. Incorporation of three GO layers in between the polyelectrolyte multilayer stacks increases Young's modulus and critical stress of the microchambers by a factor of 5.6 and 2.6, respectively. Optical density of this PEGOM film is found to decrease gradually from 0.14 at lambda = 800 nm to 0.06 at lambda = 1500 nm. Remote opening of PEGOM microchambers with NIR laser beam is also demonstrated. One of the possible applications of the developed structures includes micropackaging and delivery systems in biological tissues with remote triggering. PMID- 29575379 TI - Identification of ectopic ovotestis in a dog with XX ovotesticular, SRY-negative, disorder of sexual development. AB - A 1-year-old, previously spayed phenotypic female Poodle/Soft-coated Wheaten Terrier (Whoodle) cross was presented for a suspected ovarian remnant. Serum luteinizing hormone (LH) concentration was below the detection limit (<1 ng/ml Witness(r) LH), and serum progesterone concentration was elevated in the chemiluminescence immunoassay (CLIA; 20 ng/ml), consistent with dioestrus and presence of ovarian tissue. Transabdominal ultrasound revealed a retroperitoneal soft tissue structure suspected to be a gonad. On exploratory laparotomy, a gonad was removed from the cranial retroperitoneum, cranial to the right kidney, after ligation of its primary blood supply. Histological examination proved the gonad to be an ovotestis. Subsequent cytogenetics revealed a 78 XX karyotype, thus confirming the diagnosis of ectopic ovotestis in a XX ovotesticular, SRY negative, disorder of sexual development in a dog.

AB - The Israeli Long Term Care Insurance Law (LTCIL) was one of the first long term care insurances in the world to support older adults and their family members and allow them to stay in their homes for as long as possible. The present study aimed to evaluate the perspectives of older adults, their family members and home care workers regarding the LTCIL. Views of workers of the National Insurance Institute (NII), which is directly responsible for the enactment of the law, are also integrated. Interviews were conducted between June 2016 and June 2017. Thematic qualitative analysis is based on interviews with 15 NII workers, 31 older adults, 31 family members, and 6 paid home care workers. The present study stresses the tension between the LTCIL and older adults' perceived rights and needs. It also demonstrates how even though the NII workers are engaged with various stakeholders, they often lack direct contact with older adults, their family members and paid home care workers: those most directly influenced by the LTCIL. Policy considerations are discussed. PMID- 29575383 TI - Phaeohyphomycosis due to Pleurostomophora richardsiae: an uncommon cutaneous fungal infection. PMID- 29575385 TI - Transcranial Sonography to Differentiate Primary Intracerebral Hemorrhage from Cerebral Infarction with Hemorrhagic Transformation. AB - BACKGROUND AND PURPOSE: The differentiation of primary intracerebral hemorrhage (ICH) from parenchymal hemorrhagic transformation within an ischemic infarction (PHI) is crucial in order to adapt therapeutic measures. We hypothesized that a distinction of ICH and PHI can be made at bedside via transcranial gray-scale and perfusion sonography. METHODS: We prospectively included 14 patients with intracranial hemorrhage on admission imaging in this pilot study. Differentiation between ICH and PHI was made either by cerebral magnetic resonance imaging or follow-up computed tomography scan. All patients were examined via gray-scale and perfusion sonography. RESULTS: Eight patients were diagnosed with ICH, and 6 patients with PHI. Volumes of ICH did not differ between the two groups. However, PHI patients showed a significantly larger perfusion deficit compared to ICH patients (P < .01). At a cutoff value of 1.41 of the mismatch index of perfusion deficit and hyperechogenic lesion, the PHI diagnosis can be made with a 100% sensitivity and 100%-specificity. CONCLUSION: Differentiation of ICH and PHI via multimodal transcranial sonography with mismatch imaging is possible. Since sonographic imaging as a bedside-method is cost- as well as time-efficient, it may be a helpful tool for differentiation between these two entities particularly in critically ill patients with unclear ICH. PMID- 29575384 TI - Drivers of vegetative dormancy across herbaceous perennial plant species. AB - Vegetative dormancy, that is the temporary absence of aboveground growth for >= 1 year, is paradoxical, because plants cannot photosynthesise or flower during dormant periods. We test ecological and evolutionary hypotheses for its widespread persistence. We show that dormancy has evolved numerous times. Most species displaying dormancy exhibit life-history costs of sprouting, and of dormancy. Short-lived and mycoheterotrophic species have higher proportions of dormant plants than long-lived species and species with other nutritional modes. Foliage loss is associated with higher future dormancy levels, suggesting that carbon limitation promotes dormancy. Maximum dormancy duration is shorter under higher precipitation and at higher latitudes, the latter suggesting an important role for competition or herbivory. Study length affects estimates of some demographic parameters. Our results identify life historical and environmental drivers of dormancy. We also highlight the evolutionary importance of the little understood costs of sprouting and growth, latitudinal stress gradients and mixed nutritional modes. PMID- 29575386 TI - Involving private practitioners in the Indian tuberculosis programme: a randomised trial. AB - OBJECTIVES: To assess a multicomponent intervention to improve private practitioners (PPs) involvement in referral of presumptive pulmonary TB (PTB) cases to the Revised National TB Control Programme (RNTCP) for sputum examination. METHODS: Randomised controlled trial. We randomly allocated all 189 eligible PPs in Tumkur city, South India, to intervention or control arm. The intervention, implemented between December 2014 and January 2016, included two sets of activities, one targeted at health system strengthening (building RNTCP staff capacity to collaborate with PPs, provision of feedback on referrals through SMS) and one targeted at intervention PPs (training in RNTCP, provision of referral pads and education materials and monthly visits to PPs by RNTCP staff). Crude and adjusted referral and PTB case-finding rate ratios were calculated with negative binomial regression. RESULTS: PPs referred 836 individuals (548 from intervention and 169 from control arm PPs) of whom 176 were diagnosed with bacteriologically confirmed PTB. The proportion (95% confidence interval) of referring PPs [0.59 (0.49, 0.68) vs. 0.42 (0.32, 0.52) in the intervention and control arm, respectively], mean referral rate per PP-year [(5.7 (3.8, 8.7) vs. 1.8 (1.2, 2.8)] and smear-positive PTB case-finding rate per PP year [(1.5 (0.9, 2.2) vs. 0.6 (0.3, 0.9)] were significantly higher in the intervention than the control arm. Stratifying by qualification, a statistically significant difference in the above indicators remained only among GPs and internists. Overall, surgeons, paediatricians and gynaecologists referred few patients. PP referrals contributed to 20% of the sputum smear positive PTB cases detected by RNTCP in Tumkur city (14% were from intervention arm PPs). CONCLUSIONS: We demonstrated the effectiveness of a health system-oriented intervention to improve PP's referrals of presumptive PTB cases to RNTCP.

AB - BACKGROUND: Early identification of the subgroup of patients with major depressive disorder (MDD) in need of highly specialized care could enhance personalized intervention. This, in turn, may reduce the number of treatment steps needed to achieve and sustain an adequate treatment response. The aim of this study was to identify patient-related indicators that could facilitate the early identification of the subgroup of patients with MDD in need of highly specialized care. METHODS: Initial patient indicators were derived from a systematic review. Subsequently, a structured conceptualization methodology known as concept mapping was employed to complement the initial list of indicators by clinical expertise and develop a consensus-based conceptual framework. Subject matter experts were invited to participate in the subsequent steps (brainstorming, sorting, and rating) of the concept mapping process. A final concept map solution was generated using nonmetric multidimensional scaling and agglomerative hierarchical cluster analyses. RESULTS: In total, 67 subject-matter experts participated in the concept mapping process. The final concept map revealed the following 10 major clusters of indicators: 1-depression severity, 2 onset and (treatment) course, 3-comorbid personality disorder, 4-comorbid substance use disorder, 5-other psychiatric comorbidity, 6-somatic comorbidity, 7 maladaptive coping, 8-childhood trauma, 9-social factors, and 10-psychosocial dysfunction. CONCLUSIONS: The study findings highlight the need for a comprehensive assessment of patient indicators in determining the need for highly specialized care, and suggest that the treatment allocation of patients with MDD to highly specialized mental healthcare settings should be guided by the assessment of clinical and nonclinical patient factors. PMID- 29575389 TI - Optical Sensing of Aromatic Amino Acids and Dipeptides by a Crown-Ether Functionalized Perylene Bisimide Fluorophore. AB - The host-guest binding properties of a fluorescent perylene bisimide (PBI) receptor equipped with crown ether were studied in detail with a series of aromatic amino acids and dipeptides by UV/Vis, fluorescence and NMR spectroscopy. Fluorescence titration experiments showed that electron-rich aromatic amino acids and dipeptides strongly quench the fluorescence of the electron-poor PBI host molecule. Benesi-Hildebrand plots of fluorescence titration data confirmed the formation of host-guest complexes with 1:2 stoichiometry. Binding constants determined by global analysis of UV/Vis and fluorescence titration experiments revealed values between 103 m-1 and 105 m-1 in acetonitrile/methanol (9:1) at 23 degrees C. These data showed that amino acid l-Trp having an indole group and dipeptides containing this amino acid bind to the PBI receptor more strongly than other amino acids and dipeptides investigated here. For dipeptides containing l Trp or l-Tyr, the binding strength is dependent on the distance between the ammonium group and the aromatic unit of the amino acids and dipeptides leading to a strong sensitivity for Ala-Trp dipeptide. 1D and 2D NMR experiments also corroborated 1:2 host-guest complexation and indicated formation of two diastereomeric species of host-guest complexes. The studies have shown that a properly functionalized PBI fluorophore functions as a molecular probe for the optical sensing of aromatic amino acids and dipeptides. PMID- 29575388 TI - The ecology of patient and caregiver participation in consultations involving advanced cancer. AB - OBJECTIVE: To identify predictors of participation of patients with advanced cancer in clinical encounters with oncologists and to assess the impact of patient and caregiver participation on perceptions of physician support. METHODS: This is a secondary data analysis from the Values and Options in Cancer Care study, a cluster randomized clinical trial of a patient-centered communication intervention. Patients and caregivers completed pre-visit and post-visit health and communication measures. Audio recorded patient-caregiver (when present) physician encounters were coded for active patient/caregiver participation behaviors (eg, question asking, expressing concern) and for physicians' facilitative communication (eg, partnership-building, support). Mixed linear regression models were used to identify patient, physician, and situational factors predicting patient and patient plus caregiver communication behaviors and post-visit outcomes. RESULTS: Physician partnership building predicted greater expressions of concern and more assertive responses from patients and patient caregiver pairs. Patients' perceptions of greater connectedness with their physician predicted fewer patient expressions of concern. Patient perceptions of physician respect for their autonomy were lower among patients accompanied by caregivers. Caregiver perceptions of physician respect for patient autonomy decreased with increasing patient age and varied by site. CONCLUSIONS: In advanced cancer care, patient and caregiver communication is affected by ecological factors within their consultations. Physicians can support greater patient participation in clinical encounters through facilitative communication such as partnership-building and supportive talk. The presence of a caregiver complicates this environment, but partnership building techniques may help promote patient and caregiver participation during these visits. PMID- 29575391 TI - Surface-Doped Polystyrene Microsensors Containing Lipophilic Solvatochromic Dye Transducers. AB - Ion-selective optical microsensors based on surface-modified polystyrene (PS) beads with positively charged lipophilic solvatochromic dye (SD) on the surface were studied with K+ as model ion. Water-soluble SDs are expelled into the aqueous phase by ion exchange with the cationic analyte of interest, resulting in a detectable color change. In contrast, lipophilic SDs are more attractive, as they appear to remain anchored to the surface after expulsion from the sensing phase. This transfers just the ionic chromophore functionality into the aqueous phase and allows the system to act as a reversible, truly self-contained sensor. In this work this mechanism was evaluated with zeta-potential measurements on microsensor suspensions. It indeed provides experimental evidence for the mechanism of SD transfer, as a reversal of the zeta-potential of the PS microsensors was observed for higher potassium concentrations with valinomycin doped microspheres. For a discriminated ion such as sodium, the zeta-potential change occurs at much higher electrolyte concentrations, in agreement with sensor selectivity. Undoped microspheres showed no apparent dependence of zeta-potential on electrolyte concentration. The study also shows that the effective range of microsensor surface charge is tunable and depends on the concentration of the SD on the coating phase. PMID- 29575390 TI - Metabolome analysis for pancreatic cancer risk in nested case-control study: Japan Public Health Center-based prospective Study. AB - Discovery of a high-risk group for pancreatic cancer is important for prevention of pancreatic cancer. The present study was conducted as a nested case-control study including 170 pancreatic cancer cases and 340 matched controls of our population-based cohort study involving 30 239 subjects who answered a baseline questionnaire and supplied blood samples. Twelve targeted metabolites were quantitatively analyzed by gas chromatography/tandem mass spectrometry. Odds ratios (OR) and their corresponding 95% confidence intervals (CI) were calculated using conditional logistic regression models. Statistically significant P-value was defined as P < .05. Increasing 1,5-anhydro-d-glucitol (1,5-AG) levels were associated with a decreasing trend in pancreatic cancer risk (OR of quartile 4 [Q4], 0.50; 95% CI, 0.27-0.93; P = .02). Increasing methionine levels were also associated with an increasing trend of pancreatic cancer risk (OR of Q4, 1.79; 95% CI, 0.94-3.40: P = .03). Additional adjustment for potential confounders attenuated the observed associations of 1,5-AG and methionine (P for trend = .06 and .07, respectively). Comparing subjects diagnosed in the first 0-6 years, higher levels of 1,5-AG, asparagine, tyrosine and uric acid showed a decreasing trend for pancreatic cancer risk (P for trend = .04, .04, .04 and .02, respectively), even after adjustment for potential confounders. We found that the 12 target metabolites were not associated with pancreatic cancer risk. However, metabolic changes in the subjects diagnosed in the first 0-6 years showed a similar tendency to our previous reports. These results might suggest that these metabolites are useful for early detection but not for prediction of pancreatic cancer. PMID- 29575392 TI - Enhancement of teaching outcome through neural prediction of the students' knowledge state. AB - The neural mechanism for the dyadic process of teaching is poorly understood. Although theories about teaching have proposed that before any teaching takes place, the teacher will predict the knowledge state of the student(s) to enhance the teaching outcome, this theoretical Prediction-Transmission hypothesis has not been tested with any neuroimaging studies. Using functional near-infrared spectroscopy-based hyperscanning, this study measured brain activities of the teacher-student pairs simultaneously. Results showed that better teaching outcome was associated with higher time-lagged interpersonal neural synchronization (INS) between right temporal-parietal junction (TPJ) of the teacher and anterior superior temporal cortex (aSTC) of the student, when the teacher's brain activity preceded that of the student. Moreover, time course analyses suggested that such INS could mark the quality of the teaching outcome at an early stage of the teaching process. These results provided key neural evidence for the Prediction Transmission hypothesis about teaching, and suggested that the INS plays an important role in the successful teaching. PMID- 29575393 TI - Photodynamic inactivation of foodborne bacteria by eosin Y. AB - AIMS: The aim of this study was evaluate the effect of photodynamic inactivation mediated by eosin Y in Salmonella enterica serotype Typhimurium ATCC 14028, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923 and Bacillus cereus ATCC 11778. METHODS AND RESULTS: Bacteria (107 CFU per ml) were incubated with eosin Y at concentrations ranging from 0.1 to 10 MUmol l-1 , irradiated by green LED (lambdamax 490-570 nm) for 5, 10 and 15 min and the cellular viability was determined. Pseudomonas aeruginosa was completely inactivated when treated with 10 MUmol l-1 eosin Y for 10 min. Treatments reduced B. cereus and Salm. Typhimurium counts to 2.7 log CFU per ml and 1.7 log CFU per ml, respectively. Escherichia coli counts were slightly reduced. Staphylococcus aureus presented the highest sensitivity, being completely inactivated by eosin Y at 5 MUmol l-1 and 5 min of illumination. The reduction of cellular viability of photoinactivated Staph. aureus was also demonstrated by flow cytometry and morphological changes were observed by scanning electron microscopy. CONCLUSIONS: Eosin Y in combination with LED produced bacterial inactivation, being a potential candidate for photodynamic inactivation. SIGNIFICANCE AND IMPACT OF THE STUDY: This study evidenced the efficacy of photodynamic inactivation as a novel and promising alternative to bacterial control. PMID- 29575394 TI - Islandinium minutum subsp. barbatum subsp. nov. (Dinoflagellata), a New Organic Walled Dinoflagellate Cyst from the Western Arctic: Morphology, Phylogenetic Position Based on SSU rDNA and LSU rDNA, and Distribution. AB - A study of modern sediment from the Western Arctic has revealed the presence of a distinctive brown-colored cyst with a spherical central body bearing unbranched processes that are usually solid with a small basal pericoel. Distinctive barbs project from some processes, and process tips are usually minutely expanded into conjoined barbs. The archeopyle is apical and saphopylic. This cyst corresponds to Islandinium? cezare morphotype 2 of Head et al. (2001, J. Quat. Sci., 16:621). Phylogenetic analyses based on the small and large subunit rRNA genes infer close relationship with Islandinium minutum, the type of which is that of the genus. Re examination of specimens of I. minutum reveals the presence of minute barbs on its processes, but differences with Islandinium? cezare morphotype 2 remain based on size, process distribution, and barb development. Furthermore, the internal transcribed spacer shows I. minutum to be distinct from this morphotype. On the basis of these small but discrete differences, we propose the new subspecies Islandinium minutum subsp. barbatum subsp. nov. Molecular sequencing of other cysts encountered, namely Echinidinium karaense, an unidentified flattened cyst, and "Polykrikos quadratus", places them in the Monovela clade, the latter showing greater morphological variability than previously thought. PMID- 29575395 TI - Cost-effectiveness of endobronchial valve treatment in patients with severe emphysema compared to standard medical care. AB - BACKGROUND AND OBJECTIVE: Bronchoscopic lung volume reduction using endobronchial valves (EBV) is an effective new treatment option for severe emphysema patients without interlobar collateral ventilation. The objective of this study was to perform an economic evaluation including the costs and cost-effectiveness of EBV treatment compared with standard medical care (SoC) from the hospital perspective in the short term and long term. METHODS: For the short-term evaluation, incremental cost-effectiveness ratios (ICER) were calculated based on the 6-month end point data from the STELVIO randomized trial. For the long-term evaluation, a Markov simulation model was constructed based on STELVIO and literature. The clinical outcome data were quality-adjusted life-years (QALY) based on the EuroQol5-Dimensions (EQ5D) questionnaire, the 6-min walking distance (6MWD) and the St George's Respiratory Questionnaire (SGRQ). RESULTS: The mean difference between the EBV group and controls was ?16 721/patient. In the short-term (6 months), costs per additional QALY was ?205 129, the ICER for 6MWD was ?160 and for SGRQ was ?1241. In the long term, the resulting cost-effectiveness ratios indicate additional costs of ?39 000 per QALY gained with a 5-year time horizon and ?21 500 per QALY gained at 10 years. In comparison, historical costs per additional QALY 1 year after the coil treatment are ?738 400, 5 years after lung volume reduction surgery are ?48 415 and 15 years after double-lung transplantation are ?29 410. CONCLUSION: The positive clinical effects of EBV treatment are associated with increased costs compared with SoC. Our results suggest that the EBV treatment has a favourable cost-effectiveness profile, also when compared with other treatment modalities for this patient group. PMID- 29575397 TI - Localizing Antifungal Drugs to the Correct Organelle Can Markedly Enhance their Efficacy. AB - A critical aspect of drug design is optimal target inhibition by specifically delivering the drug molecule not only to the target tissue or cell but also to its therapeutically active site within the cell. This study demonstrates, as a proof of principle, that drug efficacy can be increased considerably by a structural modification that targets it to the relevant organelle. Specifically, by varying the fluorescent dye segment an antifungal azole was directed from the fungal cell mitochondria to the endoplasmic reticulum (ER), the organelle that harbors the drug target. The ER-localized azole displayed up to two orders of magnitude improved antifungal activity and also dramatically reduced the growth of drug-tolerant fungal subpopulations in a panel of Candida species, which are the most prevalent causes of serious human fungal infections. The principle underlying the "target organelle localization" approach provides a new paradigm to improve drug potency and replenish the limited pipeline of antifungal drugs. PMID- 29575396 TI - Changes in left ventricular strain parameters following pediatric heart transplantation. AB - STE is increasingly utilized to assess strain in a variety of pathologies. Strain measurements have demonstrated utility following HTx and may aid in the detection of rejection and CAV. Strain parameters have not been well defined in the pediatric HTx population. This study aimed to describe strain in pediatric HTx recipients compared to controls and assess changes over time. All pediatric HTx recipients with available echocardiograms (2004-2015) without rejection or CAV were identified. Longitudinal and circumferential strain was measured at <1 month, 1 year, 3 years, and 5 years post-transplant and compared to controls. A total of 218 echocardiograms were analyzed in 79 HTx recipients. At <1 month post transplant, there was a significant decrement in longitudinal strain (GLS -14.6 vs -19.2, P < .001) with concurrent augmentation of circumferential strain (GCS 27.3 vs -24.3, P = .005). By 1 year post-HTx, all strain parameters normalized and were not significantly different from the control population. In the absence of graft complications, strain parameters did not change up to 5 years post transplant. Abnormal longitudinal strain parameters are present in the early post HTx period with a compensatory increase in circumferential strain. These changes normalize by 1 year post-transplant and do not change over time in the absence of graft complications. PMID- 29575398 TI - Strong Photonic-Band-Gap Effect on the Spontaneous Emission in 3D Lead Halide Perovskite Photonic Crystals. AB - Stimulated emission in perovskite-embedded polymer opal structures is investigated. A polymer opal structure is filled with a perovskite, and perovskite photonic crystals are prepared. The spontaneous emission of the perovskite embedded in the polymer opal structures exhibits clear signatures of amplified spontaneous emission (ASE) via gain modulation. The difference in refractive-index contrast between the perovskite and the polymer opal is large enough for retaining photonic-crystals properties. The photonic band gap has a strong effect on the fluorescence emission intensity and lifetime. The stimulated emission spectrum exhibits a narrow ASE rather than a wide fluorescence peak in the thin film. PMID- 29575399 TI - Unique application of awake tracheoscopy and endobronchial ultrasound in the management of tracheal mucoepidermoid carcinoma. AB - BACKGROUND: Mucoepidermoid carcinoma of the trachea is a rare pediatric malignancy that presents unique challenges in diagnosis, operative management, and surveillance. METHODS AND RESULTS: We present a 17-year-old girl with primary tracheal mucoepidermoid carcinoma presenting in acute respiratory distress due to near-total occlusion of the tracheal airway. An algorithmic approach to preoperative planning was developed to evaluate and remove the tumor endoscopically without compromising oxygenation. After initial palliative resection, endobronchial ultrasound was uniquely applied to evaluate depth of tumor invasion, and subsequent tracheal resection with primary anastomosis was performed as curative treatment. CONCLUSION: Removal of distal tracheal masses can be performed safely with the implementation of an algorithmic approach to tumor visualization and resection. Endobronchial ultrasound can be used to evaluate the extent of tumor invasion and plan for definitive resection. PMID- 29575400 TI - Regression of left atrial diameter after kidney transplantation is associated with prolonged survival: an observational study. AB - Renal transplantation reduces the dramatically elevated risk of cardiovascular death in dialysis patients. We previously showed that left atrial diameter before transplantation predicts cardiovascular and overall mortality. Now, we investigated the association of changes in cardiac morphology after transplantation and mortality. We retrospectively analyzed data from the Austrian transplant repository using multivariable Cox and competing risk models and multivariable logistic regression for the prediction of changes in cardiac morphology. We identified 414 patients with a median follow-up of 8 years and observed a significant progression of mean diameter of left atrium (LA), right atrium and right ventricle and a significant regression of left ventricle. Complete case analysis of 243 patients with a regression of initially enlarged LA diameter had a significantly lower risk of adjusted overall and cardiovascular mortality; hazard ratio (HR 0.45, 95% CI 0.30-0.69, P < 0.001, 124 deaths), and HR of 0.43 [95% CI 0.21-0.92, P = 0.029, 48 cardiovascular (CV) deaths], respectively. Only age at transplantation was significantly associated with regression of LA (OR 0.75, 95% CI 0.60-0.93, P = 0.007). Patients with regression of LA after kidney transplantation exhibited a lower overall and CV mortality risk. Besides age, peritoneal dialysis and antihypertensive therapy were mediators of LA regression. PMID- 29575401 TI - Previously undiagnosed attention-deficit/hyperactivity disorder associated with poor metabolic control in adolescents with type 1 diabetes. AB - BACKGROUND: Managing modern diabetes treatment requires efficient executive functions. Patients with attention-deficit/hyperactivity disorder (ADHD) and type 1 diabetes have poor metabolic control and present with ketoacidosis more often than patients without ADHD. OBJECTIVE: To assess whether patients with type 1 diabetes and with indications of executive problems met criteria for ADHD, and to investigate whether these patients had difficulties achieving metabolic control. METHODS: In a hospital-based study, including 3 pediatric departments at hospitals in Stockholm and Uppsala, Sweden, questionnaires regarding executive problems had been filled out by 12- to 18-year-old patients with type 1 diabetes and their parents. Out of 166 patients with completed questionnaires, 49 were selected for a clinical study due to reported executive problems/ADHD symptoms. However, 7 already had a diagnosis of ADHD, 21 denied follow-up, 8 did not respond, leaving 13 adolescents for the clinical assessment. RESULTS: Of the clinically assessed adolescents, 9 (6 girls) met criteria for ADHD. Patients who did not respond to the follow-up and patients who were diagnosed with ADHD within the study, showed to a larger extent than the other study groups high HbA1c levels (>70 mmol/mol, 8,6%). HbA1c >70 mmol/mol (8.6%) was associated with diagnosed ADHD (prior to or within the study), odds ratio 2.96 (95% confidence interval 1.02-8.60). CONCLUSION: Patients with type 1 diabetes and poor metabolic control should be assessed with regard to ADHD. There is a need for paying special attention to girls with poor metabolic control. PMID- 29575402 TI - Mechanical Switching of Aromaticity and Homoaromaticity in Molecular Optical Force Sensors for Polymers. AB - The sensing of mechanical stress in polymers is indispensable for investigating the origin and propagation of cracks that lead to material failure and for designing mechanically responsive polymers. Here the unique approaches of using the force-induced switching of aromaticity and homoaromaticity in molecular optical force sensors for the real-time measurement of mechanical forces acting in stretched polymers are suggested. The mechanical switching of aromaticity in Dewar benzene is an irreversible event, whereas the degree of pi-orbital overlap in homoaromatic compounds like homotropylium can be adjusted progressively over a wide range of forces. Using computational methods, it is demonstrated that both approaches lead to significant changes in the visible part of the UV/Vis spectra of the force sensors upon application of weak forces (pN-nN). Polymers that incorporate such molecular force sensors therefore change their color well before material failure occurs.

PMID- 29575404 TI - Frequency and intensity of pyrethroid resistance through the CDC bottle bioassay and their association with the frequency of kdr mutations in Aedes aegypti (Diptera: Culicidae) from Mexico. AB - BACKGROUND: The control of Aedes aegypti (L.), the main urban vector that causes arboviral diseases such as dengue, Chikungunya and Zika, has proved to be a challenge because of a rapid increase in insecticide resistance. Therefore, adequate monitoring of insecticide resistance is an essential element in the control of Ae. aegypti and the diseases it transmits. We estimated the frequency and intensity (Resistance Frequency Rapid Diagnostic Test [F-RDT] and Resistance Intensity Rapid Diagnostic Test [I-RDT]) of pyrethroid resistance in populations of Ae. aegypti from Mexico using the bottle bioassay and results were related to the frequencies of knockdown resistance (kdr) mutations V1016I and F1534C. RESULTS: All populations under study were resistant to the pyrethroids: bifenthrin (99%), d-(cis-trans)-phenothrin (6.3% cis, 91.7% trans) and permethrin (99.5%) according to F-RDT, and showed moderate to high-intensity resistance at 10* the diagnostic dose (DD) in I-RDT. Frequencies of the kdr mutation V1016I in Ae. aegypti populations were correlated with moderate permethrin resistance at 10* DD, whereas F1534C mutation frequencies were correlated with high bifenthrin resistance at 5* DD. Both I1016 and C1535 were highly correlated with high intensity phenothrin resistance at 1* to 10* DD. CONCLUSIONS: This study showed that high frequencies of kdr mutations V1016I and F1534C are reflected in the results of F-RDT and I-RDT tests. Bioassays in conjunction with the characterization of genetic resistance mechanisms are indispensable in the strategic and rational management of resistance in mosquitoes.

PMID- 29575405 TI - In vitro differentiation of bovine bone marrow-derived mesenchymal stem cells into male germ cells by exposure to exogenous bioactive factors. AB - Mesenchymal stem cells (MSC) are multipotent progenitor cells defined by their ability to self-renew and give rise to differentiated progeny. Previous studies have reported that MSC may be induced in vitro to develop into different types of specialized cells including male gametes. In vitro gamete derivation technology has potential applications as an alternative method for dissemination of elite animal genetics, production of transgenic animals and conservation of endangered species. This study aimed at investigating the in vitro effect of BMP4, TGFbeta1 and RA on the potential for germ cell (GC) differentiation of bovine foetal MSC (bfMSC) derived from bone marrow (BM). The effect of BMP4, TGFbeta1 and RA was analysed on the expression of pluripotent, GC and male GC markers on bfMSC during a 21-day culture period. bfMSC cultured under in vitro conditions expressed OCT4, NANOG and DAZL, but lacked expression of mRNA of VASA, STELLA, FRAGILIS, STRA8 and PIWIL2. Treatment with exogenous BMP4 and TGFbeta1 induced a transient increase (p < .05) in DAZL and NANOG mRNA levels, respectively. However, exposure to RA was more effective in increasing (p < .05) expression of DAZL and regulating expression of OCT4 and mRNA levels of NANOG. These data suggest that bfMSC may possess potential for early GC differentiation, where OCT4, NANOG and specially DAZL may play significant roles in controlling progression along the GC lineage. PMID- 29575406 TI - Knee-high compression socks minimize head-up tilt-induced cerebral and cardiovascular responses following dynamic exercise. AB - In healthy individuals during a non-exercised state, knee-high compression socks (CS) may reduce the magnitude of lower limb venous pooling during orthostasis but are not effective at minimizing the incidence of pre-syncopal symptoms. However, exaggerated reductions in cerebral blood flow velocity (CBV) and cardiac stroke volume (SV) occur during passive head-up tilt (HUT) testing following dynamic exercise. It is unknown if CS can minimize post-exercise HUT-induced decrements in CBV and SV in this population. To test the hypothesis that CS will attenuate the reductions in SV and CBV during 60 degrees HUT following 60 minutes of moderate-intensity (60% VO2 peak) cycling exercise. Ten healthy volunteers (22.6 +/- 2.1 years, 24.1 +/- 2.5 kg/m2 ) completed pre- and post-exercise 15-minute HUT tests during randomized CS and Control (no CS) conditions. Changes in blood pressure (finger plethysmography), SV (Modelflow(r) method), and CBV (Transcranial Doppler) were measured during HUT and preceding supine rest periods. Pre-exercise HUT-induced similar (all, P > .47) reductions in SV (Control; -23.1 +/- 11.5%, CS; -20.5 +/- 10.9%) and CBV (Control; -18.1 +/- 6.3%, CS; -15.3 +/- 9.0%). However, larger post-exercise decreases in SV and CBV during HUT were observed in the Control versus CS condition. Specifically, CS attenuated the drop in SV (Control: -32.9 +/- 5.6%, CS: -24.3 +/- 11.6%; P = .01) and CBV (Control: -25.1 +/- 5.8%, CS: -17.6 +/- 7.8%; P = .02) during the post-exercise HUT test. These results indicate that CS attenuated HUT-induced reductions in SV and CBV following moderate-intensity cycling exercise and suggest that CS may be an effective countermeasure to reduce the incidence of post-exercise syncope in vulnerable populations. PMID- 29575407 TI - The evolution of individuality revisited. AB - Evolutionary theory is formulated in terms of individuals that carry heritable information and are subject to selective pressures. However, individuality itself is a trait that had to evolve - an individual is not an indivisible entity, but a result of evolutionary processes that necessarily begin at the lower level of hierarchical organisation. Traditional approaches to biological individuality focus on cooperation and relatedness within a group, division of labour, policing mechanisms and strong selection at the higher level. Nevertheless, despite considerable theoretical progress in these areas, a full dynamical first principles account of how new types of individuals arise is missing. To the extent that individuality is an emergent trait, the problem can be approached by recognising the importance of individuating mechanisms that are present from the very beginning of the transition, when only lower-level selection is acting. Here we review some of the most influential theoretical work on the role of individuating mechanisms in these transitions, and demonstrate how a lower-level, bottom-up evolutionary framework can be used to understand biological complexity involved in the origin of cellular life, early eukaryotic evolution, sexual life cycles and multicellular development. Some of these mechanisms inevitably stem from environmental constraints, population structure and ancestral life cycles. Others are unique to specific transitions - features of the natural history and biochemistry that are co-opted into conflict mediation. Identifying mechanisms of individuation that provide a coarse-grained description of the system's evolutionary dynamics is an important step towards understanding how biological complexity and hierarchical organisation evolves. In this way, individuality can be reconceptualised as an approximate model that with varying degrees of precision applies to a wide range of biological systems.

AB - BACKGROUND AND OBJECTIVE: The St George's Respiratory Questionnaire (SGRQ) is a self-administered questionnaire used to assess health-related quality of life (HRQoL) in various chronic respiratory diseases. Few studies have assessed the performance of the SGRQ in patients with connective tissue disease-associated interstitial lung disease (CTD-ILD). We aimed to examine the SGRQ's performance characteristics and generate data to support its reliability and validity in patients with CTD-ILD. METHODS: We used data from 193 CTD-ILD patients evaluated at Tosei General Hospital from May 2007 to July 2016 to assess the cross sectional and longitudinal validity of the SGRQ. RESULTS: The mean age of the patients was 64.2 years and 122 (63.2%) were women. There were no significant differences in SGRQ scores between any of the CTD groups. Internal consistency (Cronbach's alpha = 0.905) and repeatability (intraclass correlation coefficient (ICC) = 0.873) for the SGRQ total score were excellent. At baseline, SGRQ total score was significantly associated with clinically meaningful measures of physiological function, exercise capacity and dyspnoea. Change in SGRQ total score over 6 months was also associated with change in other measures. Cox proportional hazards models showed that higher baseline SGRQ total score was a significant predictor of mortality. The estimated minimal clinically important difference of SGRQ total score was 4-13 points. CONCLUSION: These data support the validity and reliability of SGRQ as a sensitive measure for capturing HRQoL in patients with CTD-ILD.

Direct analysis of drug detection in intact tissue sections provides distribution information that can impact drug development. MALDI-IMS capabilities of uncovering drug transport across the blood-brain barrier are demonstrated. METHODS: Successful peptide detection using MALDI-IMS was achieved using a MALDI TOF/TOF system. Upon optimization of sample preparation procedures for dipeptide ZP1609, an additional tissue acidification procedure was found to greatly enhance signal detection. The imaging data acquired was able to determine successful transport of ZP1609 across the blood-brain barrier. Data obtained from MALDI-IMS can help shape our understanding of biological functions, disease progression, and effects of drug delivery. RESULTS: Direct detection of ZP1609 throughout the brain tissue sections was observed from MALDI-MS images. However, in cases where there was induction of stroke, a peak of lower signal intensity was also detected in the target m/z region. Although distinct differences in signal intensity can be seen between control and experimental groups, fragments and adducts of ZP1609 were investigated using MALDI-IMS to verify detection of the target analyte. CONCLUSIONS: Overall, the data reveals successful penetration of ZP1609 across the blood-brain barrier. The benefits of tissue acidification in the enhancement of detection sensitivity for low-abundance peptides were demonstrated. MALDI-IMS has been shown to be a useful technique in the direct detection of drugs within intact brain tissue sections.

AB - Along the western margin of North America, the winter expression of the North Pacific High (NPH) strongly influences interannual variability in coastal upwelling, storm track position, precipitation, and river discharge. Coherence among these factors induces covariance among physical and biological processes across adjacent marine and terrestrial ecosystems. Here, we show that over the past century the degree and spatial extent of this covariance (synchrony) has substantially increased, and is coincident with rising variance in the winter NPH. Furthermore, centuries-long blue oak (Quercus douglasii) growth chronologies sensitive to the winter NPH provide robust evidence that modern levels of synchrony are among the highest observed in the context of the last 250 years. These trends may ultimately be linked to changing impacts of the El Nino Southern Oscillation on midlatitude ecosystems of North America. Such a rise in synchrony may destabilize ecosystems, expose populations to higher risks of extinction, and is thus a concern given the broad biological relevance of winter climate to biological systems.

AB - As nursing professionals, we believe access to healthcare is fundamental to health and that it is a determinant of health. Therefore, evidence suggesting access to healthcare is problematic for many Indigenous peoples is concerning. While biomedical perspectives underlie our current understanding of access, considering alternate perspectives could expand our awareness of and ability to address this issue. In this paper, we critique how access to healthcare is understood through a biomedical lens, how a postcolonial theoretical lens can extend that understanding, and the subsequent implications this alternative view raises for the nursing profession. Drawing on peer-reviewed published and gray literature concerning healthcare access and Indigenous peoples to inform this critique, we focus on the underlying theoretical lens shaping our current understanding of access. A postcolonial analysis provides a way of understanding healthcare as a social space and social relationship, presenting a unique perspective on access to healthcare. The novelty of this finding is of particular importance for the profession of nursing, as we are well situated to influence these social aspects, improving access to healthcare services broadly, and among Indigenous peoples specifically. PMID- 29575415 TI - Gastrointestinal dysmotility: A qualitative exploration of the journey from symptom onset to diagnosis. AB - BACKGROUND: Gastrointestinal dysmotility (GID) covers a spectrum of disorders disrupting enteric neuromuscular co-ordination which, when severe, causes intractable gastrointestinal symptoms and malnutrition and is a recognized cause of chronic intestinal failure. To date, no study has provided an in-depth account of the experiences of patients with severe GID and their psychosocial needs. This study aimed to explore patients' experiences from symptom onset and the process of seeking and receiving a diagnosis. It specifically explored the psychological effect of this process and the effect on relationships. METHODS: Participants (n = 20, mean age = 47.9, female n = 16, parenteral nutrition = 13) were recruited from a UK center with tertiary Neurogastroenterology and Intestinal Failure services. A qualitative exploratory design with semi-structured in-depth interviews was used. Data were analyzed using thematic analysis. KEY RESULTS: Significant delays were experienced in obtaining a diagnosis. Participants reported having their mental health questioned and felt that they had to fight to prove their symptoms had a physical basis to access appropriate treatment. Although a diagnosis helped legitimize symptoms, the condition remained poorly understood by participants themselves, relatives, and health professionals. Participants discussed the impact that "feeling delegitimized" and the "lack of coherent understanding of GID" had on their relationships and mental health. CONCLUSIONS & INFERENCES: The distressing experience of GID symptoms are compounded by a delay in validating symptoms and lack of coherent understanding. More knowledge of GID is needed by health professionals to speed up diagnosis and offer more coherent information. The psychological impact of a GID diagnosis should be acknowledged early to help facilitate adjustment. PMID- 29575414 TI - Evidence for the Role of Intracellular Water Lifetime as a Tumour Biomarker Obtained by In Vivo Field-Cycling Relaxometry. AB - It was established through in vivo T1 measurements at low magnetic fields that tumour cells display proton T1 values that are markedly longer than those shown by healthy tissue. Moreover, it has been found that the elongation of T1 parallels the aggressiveness of the investigated tumour. The T1 lengthening is associated with an enhanced water exchange rate across the transcytolemmal membrane through an overexpression/upregulation of GLUT1 and Na+ /K+ ATPase transporters. It follows that the intracellular water lifetime represents a hallmark of tumour cells that can be easily monitored by measuring T1 at different magnetic field strengths ranging from 0.2 to 200 mT.

AB - The controlled synthesis and structure determination of a bimetallic nanocluster Au57 Ag53 (C=CPh)40 Br12 (Au57 Ag53 ) is presented. The metal core has a four shell Au2 M3 @Au34 @Ag51 @Au20 (M=1/3 Au+2/3 Ag) architecture. In contrast to the previously reported large nanoclusters that have highly symmetric kernel structures, the metal atoms in Au57 Ag53 are arranged in an irregular manner with C1 symmetry. This cluster exhibits excellent thermal stability and is robust under oxidative or basic conditions. The silver precursors play a key role in dictating the structures of the nanoclusters, which suggests the importance of the counteranions used.

AB - BACKGROUND: Self-efficacy has been shown to play an important role in rehabilitation outcomes of stroke patients. AIM: This study aimed to determine the validity and reliability of a Turkish translation of the Stroke Self-Efficacy Questionnaire. METHODS: This methodological study was conducted in a private acute stroke unit in Istanbul, Turkey. After obtaining the Institutional Review Board's approval and site consent, a translated version of the 13-item Likert type scaled questions was tested for language and content validity. A pilot study with 10 patients was followed by recruitment of 130 stroke patient participants, with 50 patients retested after 3 weeks. RESULTS: The Stroke Self-Efficacy Questionnaire-Turkish had excellent content validity index and face validity index scores. Confirmatory factor analysis findings revealed a single factor structure that offered good model suitability. Cronbach alpha was 0.93 for the scale and its subgroups. There was no statistically significant difference between the items according to test-retest scores (P > 0.05), and a reliability index was over 0.80. CONCLUSION: The Turkish version of the Stroke Self-Efficacy Questionnaire is a valid and reliable tool, recommended for use in clinical rehabilitation and stroke self-management/self-efficacy interventions. PMID- 29575419 TI - Forty-nine cases of acute lymphoblastic leukaemia/lymphoma in pleural and pericardial effusions: A cytological-histological correlation. AB - INTRODUCTION: Acute lymphoblastic leukaemia/lymphoma (ALL/LBL) is an aggressive entity of precursor lymphoid neoplasm and may cause malignant serous effusion (SE). The current study aimed to analyse the characteristics of SE cytology of ALL/LBL including cytomorphology, immunophenotyping, clonality and evaluate the effectiveness of SE cytology as a diagnostic method for ALL/LBL. METHODS: SE specimens with final diagnosis of ALL/LBL from 2006 to 2016 were reviewed for clinical data, cytomorphological features and ancillary studies. Cytodiagnoses were compared with histodiagnoses, and the discordant cases were analysed. RESULTS: A total of 49 specimens including 47 pleural fluids and 2 pericardial fluids from 49 patients were evaluated. Cytomorphology revealed lymphoblasts varied from small size with scant cytoplasm, condensed nuclear chromatin and indistinct nucleoli to large size with dispersed nuclear chromatin and multiple variably prominent nucleoli. Nuclear clefts and hand mirror-shaped blasts were demonstrated. The positive rates of CD99 and terminal deoxynucleotidyl transferase were 90.9% and 81.6%, respectively. Both monoclonal immunoglobulin (Ig)H and T-cell receptor-gamma gene rearrangements were demonstrated in 1 of 3 cases. Monoclonal T-cell receptor-gamma gene rearrangement was found in 10 of 11 cases. Monoclonal IgH and/or Ig? gene rearrangements were revealed in 2 of 3 cases. Cytodiagnoses included 4 ALL/LBL, 3 B-ALL/LBL and 42 T-ALL/LBL. Histodiagnoses were available in 24 cases including 2 ALL/LBL, 2 B-ALL/LBL and 20 T-ALL/LBL. The concordance rates of cytological-histological diagnoses were 66.7%, 0% and 95.2% in the three categories, respectively. There were 3 cases with discrepancies of cell lineages. CONCLUSIONS: SE cytological evaluation is a reliable and effective method for the diagnosis of ALL/LBL.

AB - PURPOSE: In conventional cytology, preparation of a specimen by wet fixation for Papanicolaou stain is potentially subject to dry effect or cell loss which may make cytologic interpretation difficult or even impossible. We have been routinely making an additional smear for rehydration with normal saline (rehydration method) before wet fixation to overcome the above shortcomings. METHODS: We reviewed malignant pleural effusion and ascites 15 cases each in our cytology laboratory over the past 1 year. Four slides of each specimen were made. Two were air-dried for Liu's stain (a Romanowsky stain) and the other two were wet-fixed for Papanicolaou stain. The air-dried smears were also served as retained cellularity control. One of the two wet-fixed smears was processed as a control of preservation of nuclear detail whereas the other one stayed air-dried for 10 minutes and then covered with normal saline (rehydration method) for 80 seconds before wet fixation. RESULTS: There was minor cell loss (P = .032). The cells appeared larger with good preservation of nuclear detail (P < .0001 by two sided Wilcoxon rank sum test) but no red blood cells retained on the slide after rehydration. CONCLUSION: The rehydration method can effectively minimise cell loss, enlarge and preserve the cytological features of malignant cells with haemolysis. This method is simple, practical and good for cytological screening for tumour cells and interpretation especially in a bloody smear. We recommend that the rehydration method be part of traditional cytopreparatory work of wet fixation for Papanicolaou stain in conventional body fluid cytology. PMID- 29575422 TI - Differentiated cervical intraepithelial neoplasia-associated invasive cervical squamous cell carcinoma as a source of major cytopathological and surgical pathological discrepancy in Papanicolaou smear screening tests. AB - INTRODUCTION: Differentiated cervical intraepithelial neoplasia (dCIN) analogous to differentiated squamous intraepithelial neoplasia of the vulva is characterised by the proliferation of atypical cells limited to the basal/parabasal layers. Exfoliative cytology of dCIN has not been investigated. METHODS AND RESULTS: A 46-year-old woman, with a history of normal Papanicolaou (Pap) smear up to 2 years prior to the occurrence of postcoital vaginal bleeding had two consecutive Pap smears, which only revealed atypical squamous cells of unknown significance (ASCUS). The subsequent cervical biopsy revealed dCIN. The cone biopsy showed the invasive cervical squamous cell carcinoma (ICC) that developed from the overlying dCIN. Review of 32 consecutive cases of ICC revealed a second case of dCIN-associated ICC (Group 1) preceded by ASCUS suspicious for high-grade neoplastic cells. In both cases, the ASCUS were keratinised atypical cells without koilocytosis. In addition, there were another seven cases showing focal dCIN associated with extensive usual CIN (Group 2). In comparison with the remaining 24 cases with usual CIN (Group 3), Group 2 lesions occurred in younger patients (mean ages of 36 +/- 3 vs 47 +/- 9 years) and were associated with shorter intervals after the last normal Pap smears. Pap smears in Group 2 occasionally consisted only of ASCUS cells. CONCLUSIONS: dCIN may occur in the cervix and accounts for a short interval of normal Pap smears and false negative or low-grade Pap smears in ICC. PMID- 29575423 TI - Cytological preparations for molecular analysis: A review of technical procedures, advantages and limitations for referring samples for testing. AB - Minimally invasive procedures such as endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) must yield not only good quality and quantity of material for morphological assessment, but also an adequate sample for analysis of molecular markers to guide patients to appropriate targeted therapies. In this context, cytopathologists worldwide should be familiar with minimum requirements for refereeing cytological samples for testing. The present manuscript is a review with comprehensive description of the content of the workshop entitled Cytological preparations for molecular analysis: pre-analytical issues for EBUS TBNA, presented at the 40th European Congress of Cytopathology in Liverpool, UK. The present review emphasises the advantages and limitations of different types of cytology substrates used for molecular analysis such as archival smears, liquid-based preparations, archival cytospin preparations and FTA (Flinders Technology Associates) cards, as well as their technical requirements/features. These various types of cytological specimens can be successfully used for an extensive array of molecular studies, but the quality and quantity of extracted nucleic acids rely directly on adequate pre-analytical assessment of those samples. In this setting, cytopathologists must not only be familiar with the different types of specimens and associated technical procedures, but also correctly handle the material provided by minimally invasive procedures, ensuring that there is sufficient amount of material for a precise diagnosis and correct management of the patient through personalised care. PMID- 29575424 TI - Microarray Analysis of Oligosaccharide-Mediated Multivalent Carbohydrate-Protein Interactions and Their Heterogeneity. AB - Carbohydrate-protein interactions (CPIs) are involved in a wide range of biological phenomena. Hence, the characterization and presentation of carbohydrate epitopes that closely mimic the natural environment is one of the long-term goals of glycosciences. Inspired by the multivalency, heterogeneity and nature of carbohydrate ligand-mediated interactions, we constructed a combinatorial library of mannose and galactose homo- and hetero-glycodendrons to study CPIs. Microarray analysis of these glycodendrons with a wide range of biologically important plant and animal lectins revealed that oligosaccharide structures and heterogeneity interact with each other to alter binding preferences.

AB - Understanding the neuronal basis of disorders of consciousness can help improve the accuracy of their diagnosis, indicate potential targets for therapeutic interventions, and provide insights into the organization of normal conscious information processing. Measurements of brain activity have been used to find associations of the levels of consciousness with brain complexity, topological features of functional connectomes, and disruption of resting-state networks. However, obtainment of a detailed picture of activity patterns underlying the vegetative state/unresponsive wakefulness syndrome and the minimally conscious state remains a work in progress. We here aimed at finding the aspects of fMRI based functional connectivity that differentiate these states from each other and from the normal condition. A group of 22 patients was studied (9 minimally conscious state and 13 vegetative state/unresponsive wakefulness syndrome). Patients were shown to have reduced connectivity in most resting-state networks and disrupted patterns of relative connection strengths as compared to healthy subjects. Differences between the unresponsive wakefulness syndrome and the minimally conscious state were found in the patterns formed by a relatively small number of strongest positive correlations selected by thresholding. These differences were captured by measures of functional connectivity disruption that integrate area-specific abnormalities over the whole brain. The results suggest that the strong positive correlations between the functional activities of specific brain areas observed in healthy individuals may be critical for consciousness and be an important target of disruption in disorders of consciousness. PMID- 29575426 TI - Satisfaction guaranteed? Forensic consumer satisfaction survey. AB - Despite many people being forensically hospitalized worldwide, there is limited research reporting on their views of the care they receive. To describe consumer satisfaction and areas for improvement, we utilized our forensic psychiatric hospital's consumer survey. Eleven years of surveys, including a total of 541 surveys, were analysed both quantitatively and qualitatively. The majority of the forensic inpatients believed that their views were valued in their care and treatment. Most felt physically and emotionally safe at the hospital and believed that staff knew how to support them in times of distress. The majority felt that their culture and spirituality were respected. However, some areas for improvement were also noted, such as regarding staff attitudes. This consumer survey demonstrated a reasonably high level of satisfaction with forensic inpatient care, over the course of eleven years, despite this population of people being subject to lengthy hospitalisations. Satisfaction surveys of people in forensic inpatient units can be a regular part of forensic care and can help guide improvements in their care.

AB - A novel type of multimodal, magnetic resonance imaging/optical imaging (MRI/OI) contrast agent was developed, based on core-shell lanthanide fluoride nanoparticles composed of a beta-NaHoF4 core plus a beta-NaGdF4:Yb3+ , Tm3+ shell with an average size of ~24 nm. The biocompatibility of the particles was ensured by a surface modification with poly acrylic acid (PAA) and further functionalization with an affinity ligand, folic acid (FA). When excited using 980 nm near infrared (NIR) radiation, the contrast agent (CA) shows intense emission at 802 nm with lifetime of 791+/-3 MUs, due to the transition 3 H4 ->3 H6 of Tm3+ . Proton nuclear magnetic relaxation dispersion (1 H-NMRD) studies and magnetic resonance (MR) phantom imaging showed that the newly synthesized nanoparticles, decorated with poly(acrylic acid) and folic acid on the surface (NP-PAA-FA), can act mainly as a T1 -weighted contrast agent below 1.5 T, a T1 /T2 dual-weighted contrast agent at 3 T, and as highly efficient T2 -weighted contrast agent at ultrahigh fields. In addition, NP-PAA-FA showed very low cytotoxicity and no detectable cellular damage up to a dose of 500 MUg mL-1 . PMID- 29575428 TI - Identification of Candida albicans regulatory genes governing mucosal infection. AB - The fungus Candida albicans thrives on a variety of human mucosae, yet the fungal determinants that contribute to fitness on these surfaces remain underexplored. Here, by screening a collection of C. albicans deletion strains in a mouse model of oral infection (oropharyngeal candidiasis), we identify several novel regulatory genes that modulate the fitness of the fungus in this locale. We investigate in detail the interplay between the host mucosa and one of the identified mutants and establish that the C. albicans transcription regulator CUP9 is a key determinant of mucosal colonisation. Deletion of cup9 resulted in the formation of more foci of colonisation and heightened persistence in infected tongues. Furthermore, the cup9 mutant produced longer and denser filaments in the oral mucosa without eliciting an enhanced local immune response. Consistent with its role in oral colonisation, we show that CUP9's top target of regulation is a major effector of Candida's adherence to buccal cells. Finally, we establish that CUP9 also governs the interplay of the fungus with vaginal epithelial cells and has a role in vaginal infections, another common mucosal disease associated with Candida. Thus, our findings reveal a mechanism whereby C. albicans can regulate proliferation on mucosal surfaces.

AB - A new protocol for the deoxygenation of alcohols and the hydrogenation of alkenes under Bronsted acid catalysis has been developed. The method is based on the use of either a benzyl or isopropyl ether as a traceless hydrogen-atom donor, and involves an intramolecular hydride transfer as a key step, which is achieved in a regio- and stereoselective manner. PMID- 29575430 TI - Improvement of mimetic peroxidase activity of gold nanoclusters on the luminol chemiluminescence reaction by surface modification with ethanediamine. AB - Peroxidase is a commonly used catalyst in luminol-H2 O2 chemiluminescence (CL) reactions. Natural peroxidase has a sophisticated separation process, short shelf life and unstable activity, therefore it is important to develop peroxidases that have both high catalytic activity and good stability as alternatives to the natural enzyme. Gold nanoclusters (Au NCs) are an alternative peroxidase with catalytic activity in the luminol-H2 O2 CL reaction. In the present study, ethanediamine was modified on the surface of Au NCs forming cationic Au NCs. The zeta potential of the cationic Au NCs maintained its positive charge when the pH of the solution was between 4 and 9. The cationic Au NCs showed higher catalytic activity in the luminol-H2 O2 CL reaction than did unmodified Au NCs. A mechanism study showed that the better performance of cationic Au NCs may be attributed to the generation of 1 O2 on the surface of cationic Au NCs and a positive surface charge, for better affinity to luminol. Cationic Au NC, acting as a peroxidase mimic, has much better stability than horseradish peroxidase over a wide range of temperatures. We believe that cationic Au NCs may be useful as an artificial peroxidase for a wide range of potential applications in CL and bioanalysis. PMID- 29575431 TI - Integrated transcriptomic and proteomic analyses reveal alpha-lipoic acid regulated cell proliferation via Grb2-mediated signalling in hepatic cancer cells. AB - Hepatocellular carcinoma is the most frequent primary liver cancer worldwide. The use of antioxidants as cancer prevention and treatment agents has become a focus of research in recent years due to their limited adverse effects. Alpha lipoic acid (alpha-LA) is synthesized in the liver and is considered a naturally occurring antioxidant. In this study, a total of 4446 differentially expressed genes (2097 down-regulated and 2349 up-regulated) were identified via RNA-Seq in HepG2 cells after exposure to alpha-LA for 24 hrs. Moreover, GO and KEGG pathway analyses showed that cancer-relevant cell membrane proteins were significantly affected. An interaction network analysis predicted that Grb2 might mediate the key target pathways activated by exposure to alpha-LA. Verification of the RNA Seq and iTRAQ results confirmed that Grb2 mediated the alpha-LA-induced inhibition of cell proliferation in vitro. Furthermore, the analysis of human hepatocellular carcinoma specimens obtained from the GEO database showed that the expression of EGFR and Met correlated with that of Grb2. These findings provide a novel mechanism through which alpha-LA regulates cell proliferation via the down regulation of growth factor-stimulated Grb2 signalling. PMID- 29575432 TI - Efficacy of Percutaneous Posterior Tibial Nerve Stimulation for the Management of Fecal Incontinence in Multiple Sclerosis: A Pilot Study. AB - BACKGROUND: Fecal incontinence is a debilitating and highly prevalent problem among multiple sclerosis patients. Conservative therapies often fail to provide benefit. Posterior tibial nerve stimulation is a minimally invasive neuromodulatory therapy with proven efficacy for fecal incontinence in non neurological settings. OBJECTIVE: To evaluate the efficacy of posterior tibial nerve stimulation in treating multiple sclerosis-related fecal incontinence. METHODS: Consecutive multiple sclerosis patients with fecal incontinence that had failed conservative therapy received posterior tibial nerve stimulation between 2012 and 2015. All patients had previously undergone anorectal physiology tests and endoanal ultrasound. Patients whose Wexner incontinence score reduced below 10 post-therapy or halved from baseline were deemed responders. RESULTS: Thirty three patients (25 female, median age 43 years) were included. Twenty-three (70%) had urge, 4 (12%) passive, and 9 (27%) mixed fecal incontinence. Twenty-six (79%) were classified as responders. The majority of subjects had relapsing-remitting multiple sclerosis (67%); those had a significantly higher response rate (95% vs. 67% and 50% in primary and secondary progressive respectively, P < 0.05). Responders tended to be more symptomatic at baseline and had greater improvements in bowel symptom scores and quality of life scores with therapy. CONCLUSION: Posterior tibial nerve stimulation demonstrates potential as an effective therapy for fecal incontinence in multiple sclerosis. These findings provide the basis for future more definitive controlled studies. PMID- 29575433 TI - Gold(III) Complexes for Antitumor Applications: An Overview. AB - Gold(III) complexes have emerged as a versatile and effective class of metal based anticancer agents. The development of various types of ligands capable of stabilizing the AuIII cation and preventing its reduction under physiological conditions, such as chelating nitrogen-donors, dithiocarbamates and C^N cyclometalled ligands, has opened the way for the exploration of their potential intracellular targets and action mechanisms. At the same time, the bioconjugation of AuIII complexes has emerged as a promising strategy for improving the selectivity of this class of compounds for cancer cells over healthy tissues, and recent developments have shown that combining gold complexes with molecular structures that are specifically recognized by the cell can exploit the cell's own transport mechanisms to improve selective metal uptake. PMID- 29575434 TI - March 2018 at a glance: clinical trials, co-morbidities and treatment of mitral regurgitation. PMID- 29575435 TI - Implication of pulmonary hypertension in patients undergoing MitraClip therapy: results from the German transcatheter mitral valve interventions (TRAMI) registry. AB - AIMS: We sought to evaluate the impact of pulmonary hypertension on outcomes following MitraClip therapy. METHODS AND RESULTS: The 643 patients in the TRAnscatheter Mitral valve Interventions (TRAMI) registry were divided into three groups according to echocardiographically graded systolic pulmonary artery pressure (sPAP) (Group 1: patients with sPAP of <=36 mmHg; Group 2: patients with sPAP of 37-50 mmHg; Group 3: patients with sPAP of >50 mmHg) and followed for 1 year. Recent cardiac decompensation, aortic valve disease and tricuspid valve insufficiency were observed more frequently in patients with higher sPAP. Furthermore, logEuroSCORE, Society of Thoracic Surgeons score and age were higher with rising sPAP values. No differences were observed in mitral regurgitation (MR) severity, co-morbidities or clinical findings (New York Heart Association class, 6-min walking distance). Reduction to MR of grade 1 or lower was achieved more often in patients with lower sPAP levels (P = 0.01). In Groups 2 and 3, sPAP was reduced significantly. Major adverse cardiac or cardiovascular events (MACCEs) occurring in hospital (death, myocardial infarction, stroke; <4% in each group), as well as 30-day rates of MACCEs (6.1% in Group 1, 11.9% in Group 2, 12.4% in Group 3) and rehospitalization (18.9% in Group 1, 24.8% in Group 2, 24.8% in Group 3) did not differ significantly. At 1 year, differences in rates of mortality and MACCEs (20.3% in Group 1, 33.1% in Group 2, 34.7% in Group 3; P < 0.01) were significant. Both Groups 2 [hazard ratio (HR) 1.81, P = 0.0122] and 3 (HR 1.85, P = 0.0092) were independently predictive of death. Rehospitalization rates did not differ during follow-up. CONCLUSIONS: Despite higher mortality in patients with elevated sPAP, these data suggest the safety, feasibility and benefit of MitraClip therapy even in advanced stages of disease. An early approach might prevent the progress of pulmonary hypertension and improve outcomes. PMID- 29575436 TI - Letter from Taiwan. PMID- 29575437 TI - Meal composition influences postprandial sensations independently of valence and gustation. AB - BACKGROUND: Palatability of meals with identical composition has been shown to influence postprandial sensations. Our aim was to determine to what extent meal composition influences postprandial sensations independently of palatability. METHODS: Randomized, crossover, double-blind trial comparing the postprandial responses to a low-fat vs a high-fat test meal, with the same physical and organoleptic characteristics (taste, smell, texture, color, and temperature). The test meal consisted in 150 g hummus containing either 17.7 g fat (low-fat) or 22.3 g fat (high-fat), 19.8 g toasts, 120 mL water and 50 g apple puree. In 12 non-obese healthy men, palatability, homeostatic sensations (hunger/satiety, fullness) and hedonic sensations (digestive well-being, mood) were measured on 10 cm scales before and during the 60-min postprandial period. Comparisons between meals were performed with a two-way repeated measures ANCOVA with premeal data as co-variate. KEY RESULTS: Both test meals were rated equally palatable (palatability scores 3.8 +/- 0.3 low-fat, 3.3 +/- 0.2 high-fat; P = .156). As compared to the high-fat meal, the low-fat meal induced more satisfaction (meal effect on well-being F(1,21) = 4.92; P = .038) and tended to improve mood (meal effect F(1,21) = 3.02; P = .064), and this was associated with a non-significant decrease in satiety (meal effect F(1,21) = 2.29; P = .145) and fullness (meal effect F(1,21) = 1.57; P = .224). CONCLUSIONS AND INFERENCES: The composition of meals with equal palatability influences postprandial satisfaction, even without significant impact on homeostatic sensations, although an effect on homeostatic sensations has not been excluded. These conditioning factors may have clinical implications in patients with impaired meal tolerance or meal-related symptoms.

PMID- 29575440 TI - Facile One-Step Assembly of Bona Fide SUMO Conjugates by Chemoenzymatic Ligation. AB - The post-translational conjugation of the small ubiquitin-like modifiers (SUMOs) to target proteins occurs through a complex machinery that involves sequential action of at least three enzymes. SUMOylation performs crucial regulatory functions in several cellular processes. The availability of well-defined SUMO conjugates is necessary for untangling the mechanism of SUMOylation. However, assembly of homogeneous SUMO conjugates represents a challenge because of the multi-step synthesis involved and the unwieldiness of the reconstituted biosynthetic systems. Here we describe a simple one-step chemoenzymatic strategy for conjugating engineered SUMO (eSUMO) proteins to a prefabricated isopeptide linked SUMO target peptide. Notably, the eSUMOs were efficiently recognized by the enzymes of the SUMOylation machinery and the SUMO conjugates served as bona fide substrates for DeSUMOylating enzymes. PMID- 29575438 TI - Anti-epidermal growth factor receptor therapy concurrently with induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma. AB - Little is known about the efficacy and toxicity of anti-epidermal growth factor receptor therapy concurrently with induction chemotherapy (IC) in locoregionally advanced nasopharyngeal carcinoma (LA-NPC). The present study aimed to address this question. We identified 2848 patients with newly diagnosed LA-NPC receiving IC between January 2012 and May 2015. The propensity score matching (PSM) method was used to balance various factors and to match patients. Survival outcomes and toxicities between different groups were compared. In total, 596 patients were selected at a 1:3 ratio, with 149 in the IC + CTX/NTZ group and 447 in the IC alone group. The 3-year disease-free survival, overall survival, distant metastasis-free survival and locoregional relapse-free survival rates for IC + CTX/NTZ vs IC alone were 84.3% vs 75.2% (P = .059), 94.0% vs 87.9% (P = .053), 88.0% vs 84.9% (P = .412) and 93.3% vs 88.2% (P = .242). Multivariate analysis established a treatment group (IC vs IC + CTX/NTZ) as a prognostic predictor for DFS (hazard ratio [HR], 1.497; 95% confidence interval [CI], 1.016-2.206; P = .041) and OS (HR, 1.984; 95%, CI, 1.023-3.848; P = .043). Grade 3-4 skin reaction (15.4% vs 0.4%, P < .001) and mucositis (10.1% vs 2.7%, P < .001) were more common in the IC + CTX/NTZ group than that in the IC alone group. Our findings suggested that CTX/NTZ in combination with IC may be a more effective and promising strategy for patients with LA-NPC treated with intensity-modulated radiotherapy. PMID- 29575441 TI - Lactobacillus plantarum MTCC 9510 supplementation protects from chronic unpredictable and sleep deprivation-induced behaviour, biochemical and selected gut microbial aberrations in mice. AB - AIM: Here, we evaluated any beneficial effects of a potential probiotic bacterial strain (Lactobacillus plantarum MTCC 9510) in two different stress paradigms in mice. METHODS AND RESULTS: Lactobacillus plantarum MTCC 9510 (2 * 1010 CFU per mice) was supplemented to male Swiss albino mice either subjected to chronic unpredictable mild stress or sleep deprivation (SD) stress. Various behavioural and biochemical tests along with selected gut bacterial abundances were determined. Lactobacillus plantarum MTCC 9510 supplementation prevented stress induced behavioural despair (depression, anxiety, learning and memory, stereotypic behaviour), oxidative stress markers and inflammatory cytokines in brain and serum. Its supplementation also improved gut and blood brain barrier integrity. It also affected caecal short-chain fatty acids along with the promotion of Lactobacillus sp. and reduction in Enterobacteriaceae abundances. We also observed that two different stresses variably affected various behavioural and biochemical changes but L. plantarum MTCC 9510 supplementation most effectively prevented all these changes. CONCLUSION: We provide evidence that positive modulation of the selected beneficial gut microbial population could serve as a viable strategy to neutralize day-to-day and SD stress-induced pathological alterations. SIGNIFICANCE AND IMPACT OF THE STUDY: Therapeutic potential of this/other probiotic strains in tackling the deleterious neurobiological effects on exposure to various stress-related conditions can be explored.

AB - Ghost cell odontogenic carcinoma (GCOC) is a rare malignant neoplasm characterized by the presence of ghost cells. It is considered to arise either de novo or from a preexisting benign precursor, calcifying odontogenic cyst (COC), or dentinogenic ghost cell tumor (DGCT). We report a case of a 44-year-old Japanese male with a left maxillary tumor. The patient received treatment to resect the left maxillary cyst 25 years prior; however, the details were uncertain. The tumor was resected with clear margins. Taken together with the results of histological and immunohistochemical examinations, the tumor was categorized between GCOC and DGCT, and we diagnosed the tumor as GCOC suggesting similarity to DGCT. Further, we focused on CTNNB1, which encodes beta-catenin and is frequently mutated in COCs. In this tumor, we identified CTNNB1 Ser33Cys, one of the mutations typically found in COCs. This finding suggests that CTNNB1 is a common target for the pathogenesis of tumors accompanied by ghost cells. PMID- 29575442 TI - High temporal resolution gastric emptying breath tests in mice. AB - BACKGROUND: Gastric emptying is a complex physiological process regulating the division of a meal into smaller partitions for the small intestine. Disrupted gastric emptying contributes to digestive disease, yet current measures may not reflect different mechanisms by which the process can be altered. METHODS: We have developed high temporal resolution solid and liquid gastric emptying breath tests in mice using [13 C]-octanoic acid and off axis- integrated cavity output spectroscopy (OA-ICOS). Stretched gamma variate and 2-component stretched gamma variate models fit measured breath excretion data. KEY RESULTS: These assays detect acceleration and delay using pharmacological (7.5 mg/kg atropine) or physiological (nutrients, cold exposure stress, diabetes) manipulations and remain stable over time. High temporal resolution resolved complex excretion curves with 2 components, which was more prevalent in mice with delayed gastric emptying following streptozotocin-induced diabetes. There were differences in the gastric emptying of Balb/c vs C57Bl6 mice, with slower gastric emptying and a greater occurrence of two-phase gastric emptying curves in the latter strain. Gastric emptying of C57Bl6 could be accelerated by halving the meal size, but with no effect on the occurrence of two-phase gastric emptying curves. A greater proportion of two-phase gastric emptying was induced in Balb/c mice with the administration of PYY (8-80 nmol) 60 min following meal ingestion. CONCLUSIONS AND INFERENCES: Collectively, these results demonstrate the utility of high temporal resolution gastric emptying assays. Two-phase gastric emptying is more prevalent than previously reported, likely involves intestinal feedback, but contributes little to the overall rate of gastric emptying.

AB - Despite the high synthetic potential of nonstabilized diazo compounds, their utilization has always been hampered by stability, toxicity, and safety issues. The present method opens up access to the most reactive nonstabilized diazoalkanes. Among diazo compounds, nonstabilized alkyl diazo compounds are the least represented because of their propensity to degrade during preparation. The continuous flow oxidation process of hydrazones on a silver oxide column afforded an output stream of base- and metal-free pure diazo solution in dichloromethane. Starting from innocuous ketones and aldehydes, this methodology allows the production of a broad range of unprecedented diazoalkanes compounds in excellent yields, while highlighting their synthetic potential and the possibility of safe large-scale diazo production. PMID- 29575445 TI - Length-Dependent Manifestation of Vibration Modes Regulates a Specific Intermediate Morphology of Abeta17-42 in Different Environments. AB - Various cytotoxic mechanisms for neurodegenerative disease are induced by specific conformations of Abeta intermediates. The efforts to understand the diverse intermediate forms of amyloid oligomers have been focused on understanding the aggregation mechanism of specific morphologies for Abeta intermediates. However, these are still not easy tasks to be accomplished because the diverse conformations of Abeta intermediates can be altered during the aggregation process, even though the same Abeta monomers are present. Thus, efforts to reveal the conformational change mechanism could be a fundamental process to understand the formation of diverse Abeta intermediate conformations. Here, we evaluate the conformational characteristics of Abeta17-42 fibrillar oligomers in different environments according to the length. We observed that Abeta fibrillar oligomers optimize their inherent hydrogen bonds and configurational entropy to stabilize their structure according to the simulation time and their length increase. In addition, we revealed the role of the expressed vibration mode shape in the fibrillar oligomers' elongation and deformation processes. Our results suggest that limitations in amyloid oligomer growth and transformations of their morphologies can be regulated and controlled by modifying the vibration features. PMID- 29575447 TI - Relations of mindfulness facets with psychological symptoms among individuals with a diagnosis of obsessive-compulsive disorder, major depressive disorder, or borderline personality disorder. AB - OBJECTIVES: To explore differences in mindfulness facets among patients with a diagnosis of either obsessive-compulsive disorder (OCD), major depressive disorder (MDD), or borderline personality disorder (BPD), and healthy controls (HC), and their associations with clinical features. DESIGN AND METHOD: One hundred and fifty-three patients and 50 HC underwent a clinical assessment including measures of mindfulness (Five Facets Mindfulness Questionnaire - FFMQ), psychopathological symptoms (Symptom Check List-90-R), dissociation (Dissociative Experience Scale), alexithymia (Alexithymia Scale 20), and depression (Beck Depression Inventory-II). Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were performed to assess differences in mindfulness scores and their associations with clinical features. RESULTS: The three diagnostic groups scored lower on all mindfulness facets (apart from FFMQobserving) compared to the HC group. OCD group had a significant higher FFMQ total score (FFMQ-TS) and FFMQacting with awareness compared to the BPD group, and scored higher on FFMQdescribing compared to BPD and MDD groups. The scores in non-judging facet were significantly lower in all the three diagnostic groups compared to the HC group. Interestingly, higher FFMQ-TS was inversely related to all psychological measures, regardless of diagnostic group. CONCLUSIONS: Deficits in mindfulness skills were present in all diagnostic groups. Furthermore, we found disease specific relationships between some mindfulness facets and specific psychological variables. Clinical implications are discussed. PRACTITIONER POINTS: The study showed deficits in mindfulness scores in all diagnostic groups compared to a healthy control group. Overall, mindfulness construct has a significantly negative association with indexes of global distress, dissociative symptoms, alexithymia, and depression. Mindfulness-based interventions in clinical settings should take into account different patterns of mindfulness skills and their impact on disease-specific maladaptive cognitive strategies or symptomatology. PMID- 29575446 TI - Medication safety challenges in primary care: Nurses' perspective. AB - AIMS AND OBJECTIVES: To identify the issues surrounding medication error reporting in community nursing and improvement strategies related to medication safety. BACKGROUND: Medication-related problems have been identified from various sources in the literature. Examples of these include incident reporting by healthcare professionals, medico-legal and patient complaints and systematic identification of organisational structure. Only a few studies report on the clinicians' perceptions of medication safety in community nursing and the challenges they face within their workplace to implement medication safety initiatives. DESIGN: Qualitative design, using conversation-style interviews with experienced registered nurses in primary care roles. METHODS: Using a general iterative approach of semantic analysis, our qualitative research study was guided by an essentialist paradigm. Our method for understanding included semi structured in-depth interviews with 10 clinicians from a large community care organisation in rural Victoria in Australia. We developed an interview guide, which included open-ended questions on clinicians' experiences, perceived barriers and facilitators, and strategies to improve medication safety. RESULTS: Several barriers have been identified by healthcare practitioners that hinder medication safety in primary care including culture differences between community and hospital setting, politics within the healthcare system, lack of clarity around the nurses' roles and lack of error reporting. Other sources of errors cited by the participants were the lack of clarity or awareness of the processes and procedures of medication incidents reporting for staff within the organisation experience. Lack of education regarding medication safety, the dilemmas associated with reporting and documentation are also significant barriers. PMID- 29575448 TI - Comparison of closely related, uncultivated Coxiella tick endosymbiont population genomes reveals clues about the mechanisms of symbiosis. AB - Understanding the symbiotic interaction between Coxiella-like endosymbionts (CLE) and their tick hosts is challenging due to lack of isolates and difficulties in tick functional assays. Here we sequenced the metagenome of a CLE population from wild Rhipicephalus sanguineus ticks (CRs) and compared it to the previously published genome of its close relative, CLE of R. turanicus (CRt). The tick hosts are closely related sympatric species, and their two endosymbiont genomes are highly similar with only minor differences in gene content. Both genomes encode numerous pseudogenes, consistent with an ongoing genome reduction process. In silico flux balance metabolic analysis (FBA) revealed the excess production of L proline for both genomes, indicating a possible proline transport from Coxiella to the tick. Additionally, both CR genomes encode multiple copies of the proline/betaine transporter, proP gene. Modelling additional Coxiellaceae members including other tick CLE, did not identify proline as an excreted metabolite. Although both CRs and CRt genomes encode intact B vitamin synthesis pathway genes, which are presumed to underlay the mechanism of CLE-tick symbiosis, the FBA analysis indicated no changes for their products. Therefore, this study provides new testable hypotheses for the symbiosis mechanism and a better understanding of CLE genome evolution and diversity. PMID- 29575449 TI - Population and evolutionary dynamics in spatially structured seasonally varying environments. AB - Increasingly imperative objectives in ecology are to understand and forecast population dynamic and evolutionary responses to seasonal environmental variation and change. Such population and evolutionary dynamics result from immediate and lagged responses of all key life-history traits, and resulting demographic rates that affect population growth rate, to seasonal environmental conditions and population density. However, existing population dynamic and eco-evolutionary theory and models have not yet fully encompassed within-individual and among individual variation, covariation, structure and heterogeneity, and ongoing evolution, in a critical life-history trait that allows individuals to respond to seasonal environmental conditions: seasonal migration. Meanwhile, empirical studies aided by new animal-tracking technologies are increasingly demonstrating substantial within-population variation in the occurrence and form of migration versus year-round residence, generating diverse forms of 'partial migration' spanning diverse species, habitats and spatial scales. Such partially migratory systems form a continuum between the extreme scenarios of full migration and full year-round residence, and are commonplace in nature. Here, we first review basic scenarios of partial migration and associated models designed to identify conditions that facilitate the maintenance of migratory polymorphism. We highlight that such models have been fundamental to the development of partial migration theory, but are spatially and demographically simplistic compared to the rich bodies of population dynamic theory and models that consider spatially structured populations with dispersal but no migration, or consider populations experiencing strong seasonality and full obligate migration. Second, to provide an overarching conceptual framework for spatio-temporal population dynamics, we define a 'partially migratory meta-population' system as a spatially structured set of locations that can be occupied by different sets of resident and migrant individuals in different seasons, and where locations that can support reproduction can also be linked by dispersal. We outline key forms of within individual and among-individual variation and structure in migration that could arise within such systems and interact with variation in individual survival, reproduction and dispersal to create complex population dynamics and evolutionary responses across locations, seasons, years and generations. Third, we review approaches by which population dynamic and eco-evolutionary models could be developed to test hypotheses regarding the dynamics and persistence of partially migratory meta-populations given diverse forms of seasonal environmental variation and change, and to forecast system-specific dynamics. To demonstrate one such approach, we use an evolutionary individual-based model to illustrate that multiple forms of partial migration can readily co-exist in a simple spatially structured landscape. Finally, we summarise recent empirical studies that demonstrate key components of demographic structure in partial migration, and demonstrate diverse associations with reproduction and survival. We thereby identify key theoretical and empirical knowledge gaps that remain, and consider multiple complementary approaches by which these gaps can be filled in order to elucidate population dynamic and eco-evolutionary responses to spatio-temporal seasonal environmental variation and change. PMID- 29575450 TI - Influence of room temperature on magnesium isotope measurements by multi collector inductively coupled plasma mass spectrometry. AB - RATIONALE: We observed that the accuracy and precision of magnesium (Mg) isotope analyses could be affected if the room temperature oscillated during measurements. To achieve high-quality Mg isotopic data, it is critical to evaluate how the unstable room temperature affects Mg isotope measurements by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). METHODS: We measured the Mg isotopes for the reference material DSM-3 using MC ICP-MS under oscillating room temperatures in spring. For a comparison, we also measured the Mg isotopes under stable room temperatures, which were achieved by the installation of an improved temperature control system in the laboratory. RESULTS: The delta26 Mg values measured under oscillating room temperatures have a larger deviation (delta26 Mg from -0.09 to 0.080/00, with average delta26 Mg = 0.00 +/- 0.080/00) than those measured under a stable room temperature (delta26 Mg from -0.03 to 0.030/00, with average delta26 Mg = 0.00 +/- 0.020/00) using the same MC-ICP-MS system. CONCLUSIONS: The room temperature variation can influence the stability of MC-ICP-MS. Therefore, it is critical to keep the room temperature stable to acquire high-precision and accurate isotopic data when using MC-ICP-MS, especially when using the sample-standard bracketing (SSB) correction method.

AB - Misfolding of the protein alpha-synuclein (alphaSyn) into amyloid fibrils plays a central role in the development of Parkinson's disease. Most approaches for the inhibition of alphaSyn fibril formation are based on stabilizing the native monomeric form of the protein or destabilizing the fibrillized misfolded form. They require high concentrations of inhibitor and therefore cannot be easily used for therapies. In this work, we designed an inhibitor (Inh-beta) that selectively binds the growing ends of alphaSyn fibrils and creates steric hindrance for the binding of monomeric alphaSyn. This approach permits the inhibition of fibril formation at Inh-beta concentrations (IC50 =850 nm) much lower than the concentration of monomeric alphaSyn. We studied its kinetic mechanism in vitro and identified the reactions that limit inhibition efficiency. It is shown that blocking of alphaSyn fibril ends is an effective approach to inhibiting fibril growth and provides insights for the development of effective inhibitors of alphaSyn aggregation. PMID- 29575452 TI - Bioactivity of novel functionally structured titanium-ceramic composites in contact with human osteoblasts. AB - The aim of this study was to analyze the osteogenic cell behavior on the surface of novel functionally graded titanium-based composites containing bioactive ceramics. Titanium grade V discs (8 * 3 mm) embedding gradual content of hydroxyapatite (TiAlV-HA) or beta-tricalcium phosphate (TiAlV-betaTCP) were produced by hot-pressing technique. Titanium-ceramic composite discs and Ti grade V (control group) were placed in contact with human osteoblast culture assays. The morphology and adhesion of osteoblasts were inspected by field emission guns scanning electron microscopy (FEGSEM) while cell viability was assessed by fluorometric method. Alkaline phosphatase (ALP) activity and fluorescent microscopic analyses were used to evaluate mineralization on the test and control discs. FEGSEM images showed cells adhered to Ti6Al4V-ceramic and Ti6Al4V surfaces over a period of 24 h, and therefore, an intense proliferation of osteoblasts and spreading cells was noticed for 7 days. Cell viability increased with time on all the surfaces although TiAlV-betaTCP revealed significant higher percentage of cell viability than that recorded for TiAlV-HA (p < 0.01). TiAlV-betaTCP also showed the highest hydrophilic character. ALP levels increased on the Ti6Al4V ceramic surfaces when compared to the control group. Also, a qualitative analysis of mineralization evidenced an increase in mineral content on TiAlV-HA or TiAlV betaTCP groups. Novel functionally graded composites based on Ti grade V and hydroxyapatite or betaTCP showed a higher bioactivity in presence of osteoblasts than that recorded on Ti grade V. Also, such functionally graded materials can prevent risks of failures by detachment of bioactive ceramic materials during implant placement. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: There is a certain number of subjects that consider themselves to be constipated (self diagnosed constipation; SDC). The Rome Criteria separate FC from IBS-C, but some SDC patients do not meet the Rome criteria (no Rome Constipation; NRC). Our aims were to evaluate the percentage of SDC subjects with a diagnosis of FC and IBS-C and to compare demographic and clinical features, symptoms, and quality of life in the different SDC groups (FC, IBS-C, NRC). METHODS: During a 2-month period, 934 patients and 980 accompanying persons (AP) were asked to complete a survey. The presence of FC or IBS-C was assessed. SDC subjects were invited to record the stool consistency (Bristol scale) and to fill in the Constipation Severity Index (CSI), obstructed defecation syndrome (ODS) and patient assessment of constipation-quality of life (PAC-QoL). The use of laxatives and enemas was evaluated. KEY RESULTS: The probability of the ROME III criteria being present was higher in SDC compared with no-SDC (OR 20.5). NRC was present in 13.5% of the SDC. In the patients' group the agreement between a diagnosis of Rome III and SDC was good (K 0.62), whereas in the AP it was moderate (K 0.56). NRC showed lower mean values of ODS, CSI and PAC-QoL, higher Bristol scale and a lower use of laxatives and enemas compared to IBS-C and FC. No differences were found between IBS-C and FC. CONCLUSIONS AND INFERENCES: The Rome III criteria identify subjects with a greater clinical impact, but separation of FC and IBS-C does not seem justified. PMID- 29575455 TI - Cephalosporin-resistant Escherichia coli isolated from farm workers and pigs in northern Vietnam. AB - OBJECTIVE: Antimicrobial-resistant bacteria may be transmitted between farm workers and livestock. This study aimed to determine and compare the prevalence and the genetic determinants of cefotaxime-resistant and ESBL-producing Escherichia coli in faecal isolates from workers and pigs at 100 farms in northern Vietnam. METHODS: Farmers were interviewed about antimicrobial usage in livestock. Escherichia coli isolated on MacConkey agar containing 2 mg/l of cefotaxime (CTX) were tested for susceptibility to different cephalosporins by disc diffusion and screened for occurrence of ESBL-encoding genes by PCR. RESULTS: Antimicrobial usage was widespread and included classes regarded of critical or high importance in human medicine. Dosages were 0.5-2 times higher than recommended, and antimicrobials were often administered right until slaughter. Prevalence of CTX-resistant E. coli was 86% in farm workers and 89% in pigs. In 76% of farms, CTX-resistant E. coli were shared by pigs and farm workers. ESBL-producing E. coli were detected from pigs and workers at 66 and 69 farms, respectively. The ESBL phenotype was mainly mediated by CTX-M and to a lesser extent by TEM. Occurrence of blaCTX-M was similar in E. coli from pigs (66.7%) and humans (68.5%). CONCLUSION: The high occurrence of ESBL-producing E. coli in pig farmers and pigs could present a risk for spillover of these bacteria from pig farms into the community. Genomic studies are needed to elucidate reservoirs and transmission routes of ESBL-producing E. coli at livestock farms.

AB - The neuroprotective effect of ceria nanoparticles in the context of brain disorders has been explained by their antioxidant effect. However, the in-depth mechanism remains unknown. As resident immune cells in the brain, microglia exert a variety of functional reprogramming termed as polarization in response to stress stimuli. Herein, custom-made ceria nanoparticles were developed and found to scavenge multiple reactive oxygen species with extremely high efficiency. These nanoparticles drove microglial polarization from a pro-inflammatory phenotype to an anti-inflammatory phenotype under pathological conditions. Pretreatment of these nanoparticles changed the microglial function from detrimental to protective for the neuronal cells by blocking the pro-inflammatory signaling. This work not only helps to elucidate the mechanism of ceria nanoparticle-mediated neuroprotection but also provides a new strategy to rebalance the immuno-environment by switching the equilibrium of the phenotypic activation of microglia. PMID- 29575462 TI - The challenge of the biosciences in nurse education: A literature review. AB - AIMS AND OBJECTIVES: To review relevant literature that addresses the challenges of the biosciences in nurse education. More precisely, the review aims to explore the literature, concerning students' learning, learning contexts and methodological issues and identify any significant gaps. BACKGROUND: Knowledge of anatomy, physiology and biochemistry is essential for the understanding of human beings and for full appreciation of the concepts of illness and disease. The current status would seem to be that the required competencies within bioscience subjects are difficult to acquire and students have high rates of failure. DESIGN: Integrative review. METHODS: The research was performed on CINAHL, ERIC, Medline and British Nursing Index databases in a period from 2013-2017. Descriptive analytical methods were used for the initial research trawl. FINDINGS: The search strategy resulted in 23 papers. The results of this review shed light on certain deficiencies in the research field looking at the biosciences in nurse education. There is a distinct lack of intervention studies and, thereby, knowledge of how best to support students' learning in effective ways. Of note is that there are no field study approaches identified in the review sample. CONCLUSION: Many of the papers are single studies and course evaluations which may be seen as too narrow and inadequate as perspective. Students appear satisfied with the courses in the biosciences, but there seems to be no correlation between satisfaction and achievement. RELEVANCE TO CLINICAL PRACTICE: Understanding and being able to give coherent rationales for the bioscience content in the nursing curricula are crucial and must be established in relation to its relevance to the dynamic nature of patient care, technological advances and demographic realities. Only on that basis can the primacy of this content be seen as relevant to the aspiring student nurse. PMID- 29575463 TI - Environmental microbiology to the rescue of planet earth. AB - Environmental Microbiology has undergone a dramatic transition from being a somewhat marginal branch of Life Sciences to becoming one of the most vibrant and visible areas of contemporary research. The homonymous journal has not only borne witness of the growing interest in environmental microbes that bloomed since the mid-1980s but it has helped also to give visibility to the field and nucleate an active and influential community of authors and readers. During the past 20 years the focus has shifted from individual isolates to communities and microbiomes, from single genomes to metagenomes and from small/medium-scale experimental systems to large/very large scenarios. New challenges that were somewhat marginal when the journal was founded have acquired an unanticipated relevance owing to their impact on the global Earth's homeostasis. They include the unacceptably high atmospheric levels of greenhouse gases, the worrying pollution of the oceans with very recalcitrant plastics and microplastics and the noxious effects of micropollutants on many ecosystems. Global problems ask for global solutions and the environmental microbiome - because of its dimension and its amazing activities - may end up being out best instrument to both counter the impact of industrial development and enable a new, sustainable partnership with Nature. PMID- 29575464 TI - Tumor necrosis factor-alpha induces prostate cancer cell migration in lymphatic metastasis through CCR7 upregulation. AB - Understanding the mechanism of lymph node metastasis, a poor prognostic sign for prostate cancer, and the further dissemination of the disease is important to develop novel treatment strategies. Recent studies have reported that C-C chemokine receptor 7 (CCR7), whose ligand is CCL21, is abundantly expressed in lymph node metastasis and promotes cancer progression. Tumor necrosis factor alpha (TNF-alpha) is chronically produced at low levels within the tumor microenvironment. The aim of this study was to determine whether TNF-alpha promotes prostate cancer dissemination from metastatic lymph nodes through activation of the CCL21/CCR7 axis. First, human prostate cancer cells were determined to express both TNF-alpha and CCR7. Second, low concentrations of TNF alpha were confirmed to induce CCR7 in prostate cancer cells through phosphorylation of ERK. Finally, CCL21 was found to promote the migration of prostate cancer cells through phosphorylation of the protein kinase p38. Our results suggest that TNF-alpha leads to the induction of CCR7 expression and that the CCL21/CCR7 axis might increase the metastatic potential of prostate cancer cells in lymph node metastasis. PMID- 29575465 TI - Reversible Switching between Highly Porous and Nonporous Phases of an Interpenetrated Diamondoid Coordination Network That Exhibits Gate-Opening at Methane Storage Pressures. AB - Herein, we report that a new flexible coordination network, NiL2 (L=4-(4-pyridyl) biphenyl-4-carboxylic acid), with diamondoid topology switches between non-porous (closed) and several porous (open) phases at specific CO2 and CH4 pressures. These phases are manifested by multi-step low-pressure isotherms for CO2 or a single-step high-pressure isotherm for CH4 . The potential methane working capacity of NiL2 approaches that of compressed natural gas but at much lower pressures. The guest-induced phase transitions of NiL2 were studied by single crystal XRD, in situ variable pressure powder XRD, synchrotron powder XRD, pressure-gradient differential scanning calorimetry (P-DSC), and molecular modeling. The detailed structural information provides insight into the extreme flexibility of NiL2 . Specifically, the extended linker ligand, L, undergoes ligand contortion and interactions between interpenetrated networks or sorbate sorbent interactions enable the observed switching.

AB - Polycarbazoles with rigid skeletons and electron-rich conjugated systems are beneficial to form permanent porous materials with intrinsic photoelectric properties. In recent years, the research related to porous polycarbazoles becomes a hot topic in the field of porous organic polymers. The preparation methods for porous polycarbazoles are diverse, commonly represented by the oxidation coupling reaction and the Friedel-Crafts reaction. Other methods such as nitrile-based trimerization, electrochemical polymerization, and classic C-C coupling reactions are also reported. Porous polycarbazoles generally possess large specific surface area, permanent pore structure, and high thermal and chemical stability, which show potential applications in gas storage and separation, catalysis, sensors, and electronics. In this review, the recent research progress on the synthetic methods, functions, and applications of porous polycarbazoles is summarized.

Comparison of mouse to human impact on cellular senescence in the colon. AB - Calorie restriction (CR) is an effective strategy to delay the onset and progression of aging phenotypes in a variety of organisms. Several molecular players are involved in the anti-aging effects of CR, but mechanisms of regulation are poorly understood. Cellular senescence-a cellular state of irreversible growth arrest-is considered a basic mechanism of aging. Senescent cells accumulate with age and promote a number of age-related pathologies. Whether environmental conditions such as diet affect the accumulation of cellular senescence with age is still unclear. Here, we show that a number of classical transcriptomic markers of senescent cells are reduced in adult but relatively young mice under CR. Moreover, we demonstrate that such senescence markers are not induced in the colon of middle-age human volunteers under CR in comparison with age-matched volunteers consuming normal Western diets. Our data support the idea that the improvement in health span observed in different organisms under CR might be partly due to a reduction in the number of senescent cells. PMID- 29575470 TI - Mechanism of bisphenol AF-induced progesterone inhibition in human chorionic gonadotrophin-stimulated mouse Leydig tumor cell line (mLTC-1) cells. AB - Bisphenol AF (BPAF) has been shown to inhibit testicular steroidogenesis in male rats. However, the precise mechanisms related to the toxic effects of BPAF on reproduction remain poorly understood. In the present study, a mouse Leydig tumor cell line (mLTC-1) was used as a model to investigate the mechanism of steroidogenic inhibition and to identify the molecular target of BPAF. Levels of progesterone and the concentration of cyclic adenosine monophosphate (cAMP) in cells exposed to BPAF were detected, and expression of key genes and proteins in steroid biosynthesis was assessed. The results showed that BPAF exposure decreased human chorionic gonadotrophin (hCG)-stimulated progesterone production in a dose-dependent manner. The 24-h IC50 (half maximal inhibitory concentration) value for BPAF regarding progesterone production was 70.2 uM. A dramatic decrease in cellular cAMP concentration was also observed. Furthermore, BPAF exposure inhibited expression of genes and proteins involved in cholesterol transport and progesterone biosynthesis. Conversely, the protein levels of steroidogenic acute regulatory protein (StAR) were not altered, and those of progesterone were still decreased upon 22R-hydroxycholesterol treatment of cells exposed to higher doses of BPAF. Together, these data indicate that BPAF exposure inhibits progesterone secretion in hCG-stimulated mLTC-1 cells by reducing expression of scavenger receptor class B type I (SR-B1) and cytochrome P450 (P450scc) due to the adverse effects of cAMP. However, StAR might not be the molecular target in this process. PMID- 29575472 TI - Placement of Single Proteins within the SERS Hot Spots of Self-Assembled Silver Nanolenses.

A robust coating protocol enabled the functionalization of differently sized silver nanoparticles with DNA single strands of orthogonal sequence. Coated particles 10 nm, 20 nm, and 60 nm in diameter were self-assembled by DNA origami scaffolds to form silver nanolenses. Single molecules of the protein streptavidin were selectively placed in the gap of highest electric field enhancement. Streptavidin labelled with alkyne groups served as model analyte in surface-enhanced Raman scattering (SERS) experiments. By correlated Raman mapping and atomic force microscopy, SERS signals of the alkyne labels of a single streptavidin molecule, from a single silver nanolens, were detected. The discrete, self-similar aggregates of solid silver nanoparticles are promising for plasmonic applications.

Traditional testing typically requires multiple experimental settings, captures only snapshots of behavior and involves human intervention. The recent development of automated home cage monitoring offers an alternative method to study mouse behavior in their familiar and social environment, and over weeks. Here, we used the IntelliCage system to test this approach for mouse phenotyping, and studied mice lacking Gpr88 that have been extensively studied using standard testing. We monitored mouse behavior over 22 days in 4 different phases. In the free adaptation phase, Gpr88 -/- mice showed delayed habituation to the home cage, and increased frequency of same corner returns behavior in their alternation pattern. In the following nose-poke adaptation phase, non-habituation continued, however, mutant mice acquired nose-poke conditioning similar to controls. In the place learning and reversal phase, Gpr88-/- mice developed preference for the water/sucrose corner with some delay, but did not differ from controls for reversal. Finally, in a fixed schedule-drinking phase, control animals showed higher activity during the hour preceding water accessibility, and reduced activity after access to water was terminated. Mutant mice did not show this behavior, showing lack of anticipatory behavior. Our data therefore confirm hyperactivity, non-habituation and altered exploratory behaviors that were reported previously. Learning deficits described in other settings were barely detectable, and a novel phenotype was discovered. Home cage monitoring therefore extends previous findings and shows yet another facet of GPR88 function that deserves further investigation. PMID- 29575473 TI - Molecular Modeling Approach to Determine the Flory-Huggins Interaction Parameter for Polymer Miscibility Analysis. AB - In this work, we present a thorough procedure for estimating the Flory-Huggins chi-parameter for use in atomistic and mesoscale molecular simulations in computational materials science. In particular, we propose improvements upon traditional Flory-Huggins theory by implementing a Connolly volume normalization (CVN). We apply this technique to several test systems, including a blend of poly (epichlorohydrin) and poly (methyl acrylate), a blend of polyethylene glycol and poly (methyl methacrylate), a blend of polystyrene and deuterated polystyrene, and three molecular-weight variants (monomer, dimer, and trimer) of a triblock copolymer for use in multicompartment micelle applications. Our results demonstrate that the newly developed procedure offers high accuracy and efficiency in predicting the Flory-Huggins chi-parameter for miscibility analysis compared to traditional experimental and computational methods. There are still several factors that cause the magnitude of the chi-parameter to vary between simulations performed on molecular species with the same identity but different degrees of polymerization; although we discuss possible explanations for these factors, this is nonetheless a primary focus for further exploration into this new methodology.

AB - Neonatal abstinence syndrome (NAS) due to in-utero opioid exposure has significant variability of severity. Preliminary studies have suggested that epigenetic variation within the MU-opioid receptor (OPRM1) gene impacts NAS. We aimed to determine if DNA methylation in OPRM1 within opioid-exposed mother infant dyads is associated with differences in NAS severity in an independent cohort. Full-term opioid-exposed newborns and their mothers (N = 68 pairs) were studied. A DNA sample was obtained and then assessed for level of DNA methylation at 20 CpG sites within the OPRM1 promoter region by next-generation sequencing. Infants were monitored for NAS and treated with replacement opioids according to institutional protocol. The association between DNA methylation level at each CpG site with NAS outcome measures was evaluated using linear and logistic regression models. Higher methylation levels within the infants at the -18 (11.4% vs 4.4%, P = .0001), -14 (46.1% vs 24.0%, P = .002) and +23 (26.3% vs 12.9%, P = .008) CpG sites were associated with higher rates of infant pharmacologic treatment. Higher levels of methylation within the mothers at the -169 (R = 0.43, P = .008), -152 (R = 0.40, P = .002) and +84 (R = 0.44, P = .006) sites were associated point wise with longer infant length of stay. Maternal associations remained significant point-wise for -169 (beta = 0.07, P = .007) and on an experiment-wise level for +84 (beta = -0.10, P = .003) using regression models. These results suggest an association of higher levels of OPRM1 methylation at specific CpG sites and increased NAS severity, replicating prior findings. These findings have important implications for personalized treatment regimens for infants at high risk for severe NAS.

AB - The incorporation of C-glycosides in drug design has become a routine practice for medicinal chemists. These naturally occurring building blocks exhibit attractive pharmaceutical profiles, and have become an important target of synthetic efforts in recent decades. Described herein is a practical, scalable, and versatile route for the synthesis of non-anomeric and unexploited C-acyl glycosides through a Ni/photoredox dual catalytic system. By utilizing an organic photocatalyst, a range of glycosyl-based radicals are generated and efficiently coupled with highly functionalized carboxylic acids at room temperature. Distinctive features of this transformation include its mild conditions, impressive compatibility with a wide array of functional groups, and most significantly, preservation of the anomeric carbon: a handle for further, late stage derivatization. PMID- 29575476 TI - Quality of head and neck radiotherapy reporting in randomized controlled trials. AB - BACKGROUND: The purpose of this clinical review was to determine the quality reporting of radiotherapy (RT) in randomized controlled trials (RCTs) of head and neck cancer and its impact on reporting of the trial primary efficacy and toxicity outcomes. METHODS: We searched MEDLINE for eligible RCTs published between 1994 and 2015. We assessed the quality of RT reporting and bias in the reporting of trial outcomes using published criteria. RESULTS: We found 67 eligible trial reports. There was significant variability in the quality of RT treatment reporting among the included trials. Thirty-two trials had adequate quality RT reporting. Cooperative group trials were more likely to have adequate quality reporting (odds ratio [OR] 3.02; 95% confidence interval [CI] 1.04-9.85). The quality of RT reporting did not influence the bias in the reporting of trial outcomes. CONCLUSION: The quality of head and neck RT reporting in RCTs is variable and did not impact on bias in reporting of trial outcomes. PMID- 29575477 TI - Ribosome display and selection of single-chain variable fragments effectively inhibit growth and progression of microspheres in vitro and in vivo. AB - Distinguishing the surface markers of cancer stem cells (CSCs) is a useful method for early diagnosis and treatment of tumors, as CSCs may participate in tumorigenesis and metastasis by migrating into the circulatory system. However, the potential targets of CSCs are expressed at low levels in the natural state and are always changing. Thus, dynamic screening has been reported to be an effective measure for exploring CSC markers. In recent years, diverse single chain variable fragments (scFvs) have been widely used in immunotherapy. In this study, we determined that the scFvs, screened using RD, had a high affinity to microspheres and could inhibit their progression. We also observed that the selected scFvs underwent evolution in vitro, and antitumor-associated proteins were successfully expressed. Combined with chemotherapy, the scFvs had a synergistic effect on the inhibition of the microspheres' progression in vitro and in vivo, which could be ascribed to their high affinity for stem-like cells and the inhibition of the microspheres' collective behaviors. In addition, proteins inhibiting CD44+ /CD24+ and MAPK were involved. Our data indicated that dynamic screening of the scFvs in a natural state was of great significance in the inhibition of the microspheres in vitro and in vivo. PMID- 29575478 TI - Vesicle Tubulation with Self-Assembling DNA Nanosprings. AB - A major goal of nanotechnology and bioengineering is to build artificial nanomachines capable of generating specific membrane curvatures on demand. Inspired by natural membrane-deforming proteins, we designed DNA-origami curls that polymerize into nanosprings and show their efficacy in vesicle deformation. DNA-coated membrane tubules emerge from spherical vesicles when DNA-origami polymerization or high membrane-surface coverage occurs. Unlike many previous methods, the DNA self-assembly-mediated membrane tubulation eliminates the need for detergents or top-down manipulation. The DNA-origami design and deformation conditions have substantial influence on the tubulation efficiency and tube morphology, underscoring the intricate interplay between lipid bilayers and vesicle-deforming DNA structures. PMID- 29575479 TI - Increasing autophagy and blocking Nrf2 suppress laminopathy-induced age-dependent cardiac dysfunction and shortened lifespan. AB - Mutations in the human LMNA gene cause a collection of diseases known as laminopathies. These include myocardial diseases that exhibit age-dependent penetrance of dysrhythmias and heart failure. The LMNA gene encodes A-type lamins, intermediate filaments that support nuclear structure and organize the genome. Mechanisms by which mutant lamins cause age-dependent heart defects are not well understood. To address this issue, we modeled human disease-causing mutations in the Drosophila melanogaster Lamin C gene and expressed mutant Lamin C exclusively in the heart. This resulted in progressive cardiac dysfunction, loss of adipose tissue homeostasis, and a shortened adult lifespan. Within cardiac cells, mutant Lamin C aggregated in the cytoplasm, the CncC(Nrf2)/Keap1 redox sensing pathway was activated, mitochondria exhibited abnormal morphology, and the autophagy cargo receptor Ref2(P)/p62 was upregulated. Genetic analyses demonstrated that simultaneous over-expression of the autophagy kinase Atg1 gene and an RNAi against CncC eliminated the cytoplasmic protein aggregates, restored cardiac function, and lengthened lifespan. These data suggest that simultaneously increasing rates of autophagy and blocking the Nrf2/Keap1 pathway are a potential therapeutic strategy for cardiac laminopathies. PMID- 29575480 TI - Activation of PhoBR under phosphate-rich conditions reduces the virulence of Xanthomonas oryzae pv. oryzae. AB - The two-component signal transduction system PhoBR regulates the adaptation to phosphate limitation and the virulence of many animal bacterial pathogens. However, PhoBR in phytopathogens has rarely been investigated. In this study, we found that PhoBR in Xanthomonas oryzae pv. oryzae (Xoo), the pathogen of rice bacterial leaf blight, also regulates the adaptation to phosphate starvation. Unexpectedly, rice leaves infected by the phoBR-deleted mutant and wild-type PXO99A showed similar lesions, indicating that PhoBR is unnecessary for the virulence of Xoo. phoBR was found to be silenced during host infection, whereas artificially constitutive PhoBR expression attenuated virulence on host rice and growth in phosphate-rich media. RNA-sequencing (RNA-seq) was then performed to investigate the global effect caused by constitutive PhoBR activation. RNA-seq and further experiments revealed that the PhoBR regulon in Xoo comprised a wide range of genes. Nutrient transport and metabolism readjustments that resulted from PhoBR regulon activation may be responsible for growth attenuation. Our findings suggest that growth reduction regulated by PhoBR is a fitness cost of adaptation to phosphate starvation. PhoBR in Xoo is activated under phosphate limited conditions, which could exist in epiphytic and saprophytic surviving phases, and is strictly repressed within phosphate-rich host plants to minimize fitness costs. PMID- 29575481 TI - Counterion Specificity of Polyelectrolyte Brushes: Role of Specific Ion-Pairing Interactions. AB - We demonstrate here that the properties of poly (2-(methacryloyloxy) ethyl trimethylammonium chloride) brushes can be tuned by counterion species. When the brushes are exposed to external chloride (Cl- ) counterions, obvious dehydration and collapse are only observed at high salt concentrations. In the presence of very strongly chaotropic perchlorate (ClO4- ), the brushes strongly dehydrate and collapse at a very low salt concentration. For the strongly chaotropic thiocyanate ion (SCN- ), the changes in hydration and conformation of the brushes are similar to those observed for ClO4- but at a smaller extent at very low salt concentrations. With the addition of kosmotropic acetate (Ac- ), hydration of the brushes increases, accompanied by a swelling of the brushes in the low-salt concentration regime. In contrast, the brushes dehydrate and collapse with increasing concentration of Ac- in the high-salt-concentration regime. The counterion specificity of the brushes demonstrated here is determined by specific ion-pairing interactions through modulating the osmotic pressure within the brushes and the hydrophobicity of the ion pairs. PMID- 29575483 TI - Psychosis and sexual abuse: An interpretative phenomenological analysis. AB - OBJECTIVES: This study aimed to investigate the first-person perspective of psychosis sufferers who survived childhood sexual abuse. METHODS: Interpretative phenomenological analysis was employed to explore the experiences of 7 women with a history of sexual abuse and psychosis. RESULTS: Analysis generated six themes: (a) degradation of self, interlinking shame, guilt, and sometimes disgust; (b) body-self entrapment, experiencing bodily constraint and distortion; (c) a sense of being different to others, involving interpersonal problems; (d) unending struggle and depression, a pervasive sense of defeat; (e) psychotic condemnations and abuse, describing psychotic phenomena related to harm and sexual abuse; and (f) perception of links to the past, the links made from past abuse to current functioning. CONCLUSION: Participants suffered extreme psychological, physical, and interpersonal difficulties past and present. Psychotic experiences reported exhibited themes of condemnation by external entities and reflected the topic of sexual abuse. Participants did not generally link psychosis to their past abusive experiences. PMID- 29575484 TI - Shared decision-making in tinnitus care - An exploration of clinical encounters. AB - OBJECTIVES: This study examined clinical encounters between clinicians and patients to determine current practice for the diagnosis and treatment of tinnitus. The objective was to develop an understanding of the ideal clinical encounter that would facilitate genuine shared decision-making. DESIGN: Video ethnography was used to examine clinical encounters for the diagnosis and treatment of tinnitus. METHODS: Clinical encounters were video-recorded. Patients were interviewed individually following their clinic appointment. Data were analysed using constant comparison techniques from Grounded Theory. Initial inductive analyses were then considered against theoretical conceptualizations of the clinician-patient relationship and of the clinical encounter. RESULTS: Alignment between clinician and patient was found to be essential to a collaborative consultation and to shared decision-making. Clinician groups demonstrated variation in behaviour in the encounter; some asked closed questions and directed the majority of the consultation; others asked open questions and allowed patients to lead the consultation. CONCLUSIONS: A shift away from aetiology and physiological tests is needed so that tinnitus is managed as a persistent unexplained set of symptoms. This uncertainty is challenging for the medical professionals; lessons could be learned from the use of therapeutic skills. Further research is required to test techniques, such as the use of decision aids, to determine how we might create the ideal clinical encounter. Statement of contribution What is already known on this subject? Tinnitus is a condition in which sound is heard in the absence of an external source. Current approaches to managing tinnitus vary depending on clinical site (Hoare & Hall, ). In most instances, tinnitus does not have a straightforward medical cause. Tinnitus care is challenging to traditional biomedical encounters because the process of diagnosis may not lead to a defined treatment. Clinicians are required to consider not only what the tinnitus sounds like but more importantly, what it means for the affected individual. This requires a careful and skilled approach to eliciting a patient's current behaviour, coping, and preferences for both outcomes and treatment approaches. What does this study add? We provide the first in-depth description of decision-making in clinical services for tinnitus. Findings suggest a shift in focus is required to move away from the current prioritization of the biomedical treatment of tinnitus. There is variation to the extent different clinicians were able to deal with the uncertainty presented by the symptoms of tinnitus. PMID- 29575485 TI - Impact of a fatigue management in work programme on meeting work demands of individuals with rheumatic diseases: A pilot study. AB - INTRODUCTION: Work disability and job loss are serious consequences of rheumatic diseases (RDs), and fatigue is a symptom of RDs commonly reported to have an impact on work performance. A FAtigue ManagEment in Work (FAME-W) programme was developed to facilitate the self-management of fatigue in work. The present pilot study explored if FAME-W could facilitate individuals with RDs to manage fatigue in work and improve their ability to meet work demands. METHODS: Twenty-seven individuals with a variety of rheumatic diagnoses completed a 4-week, 2-h occupational therapy-led self-management programme. Each week focused on fatigue related topics, including fatigue and activity management, pain management and joint protection, mental well-being, effective communication with employers and work colleagues, and employment legislation. Individual workplace ergonomic assessments were also offered. Study measures (work function, fatigue, pain, mood and self-efficacy) were completed prior to starting FAME-W, immediately post intervention and 12 weeks post-intervention. RESULTS: Participants (56% male) had a mean age of 43 years. No significant improvements were observed immediately post-programme. However, at the 12-week follow-up, significant improvements were reported in meeting work demands (scheduling [p = 0.046], output [p = 0.002], physical [p = 0.003], mental [p = 0.016]), fatigue [p = 0.001], pain [p = 0.01], anxiety [p = 0.001], depression [p < 0.001], self-efficacy [p < 0.001] and Arthritis Impact Measurement Scales 2-Short Form (physical: p = 0.005; symptoms: p = 0.010; affect: p = 0.010; social: p = 0.001). CONCLUSIONS: Significant improvements were reported in participants' ability to meet various demands of their work 3 months post-FAME-W. These findings suggest that FAME-W has the potential to assist individuals with RDs to meet the demands of their work, although further research is required to test the effectiveness of this intervention. PMID- 29575486 TI - The Myosin5-mediated actomyosin motility system is required for Verticillium pathogenesis of cotton. AB - The vascular wilt fungus Verticillium dahliae is one of the most destructive pathogens of cotton (Gossypium hirsutum) and many other economically important dicot plants. Fungal pathogens require Myosin-mediated actomyosin motility system for colonization of their host plants; however, the mechanisms underlying this process have not been fully characterized for V. dahliae. Here, in a knock-out experiment, we characterized the role of VdMyo5, a member of the Myosin V family, before and during infection of cotton and Arabidopsis thaliana. The VdMyo5 deletion mutant (DeltaVdmyo5) fungi showed obvious defects in the development of conidia and the polarized elongation of vegetative hyphae, but no inhibition of host root penetration. Overall, the DeltaVdmyo5 fungi exhibited dramatically reduced virulence in cotton and Arabidopsis, with almost no colonization in sections of host vascular tissue. We found labelled Myosin5-GFP to be specifically enriched at the hyphal tip, co-localized with FM4-64 labelled Spitzenkorper, which is the vesicle supply centre in filamentous fungi. Comparative secretome analysis revealed that proteins associated with cell wall modification and degradation of reactive oxygen species were significantly altered in mutant strains. Our results indicate that Myosin5 is required for vegetative growth and full virulence, possibly by regulating vesicle transport. The findings provide important insight into the cellular mechanisms of Verticillium pathogenesis. PMID- 29575488 TI - A randomized controlled clinical trial to assess crestal bone remodeling of four different implant designs. AB - BACKGROUND: It is claimed that bone remodeling is limited when the implant neck has microthreads and an internal abutment connection. However, comparative studies, excluding confounding factors, are scarce. AIM: This RCT aims to assess whether a coronal microthreaded design and an internal abutment connection affects crestal bone loss, up to one year of function. MATERIALS AND METHODS: Twenty-one maxillary edentulous patients were consecutively treated for a bar supported maxillary overdenture on four different implants with respectively: internal connection and microthreads on the implant neck (I MT); internal connection, no microthreads (I NMT), external connection, with microthreads (E MT), and external connection, without microthreads (E NMT). Other design features, s.a. width, surface topography, platform switch as well as surgical placement and prosthetic protocol were consistent. Implant survival and crestal bone loss in relation to the implant type were considered the main variables and a Friedman test for ordered alternatives was used to assess the difference in crestal bone loss between the different study implants. RESULTS: Twenty-one patients received 83 study implants. Three implants failed within three months and required replacement. The total survival rate was 96.39% after one year and based on 21 patients and 80 implants a mean crestal bone loss of 0.25 mm (SD: 0.38; range: 0-1.48) was measured. After a follow-up of 3, 6, 12, and 21 months no statistically significant differences in crestal bone loss between the different study implants or the different time intervals could be identified. CONCLUSIONS: From this RCT, it is concluded that the implant-abutment connection and a microthreaded external thread configuration have limited influence on crestal bone remodeling. The latter can be considered a multifactorial process and is more dependent on other factors such as biologic considerations than on implant design. PMID- 29575487 TI - PDK1 governs thromboxane generation and thrombosis in platelets by regulating activation of Raf1 in the MAPK pathway. AB - : Essentials Phosphoinositide 3-kinase and MAPK pathways crosstalk via PDK1. PDK1 is required for adenosine diphosphate-induced platelet activation and thromboxane generation. PDK1 regulates RAF proto-oncogene Ser/Thr kinase (Raf1) activation in the MAPK pathway. Genetic ablation of PDK1 protects against platelet-dependent thrombosis in vivo. SUMMARY: Background Platelets are dynamic effector cells with functions that span hemostatic, thrombotic and inflammatory continua. Phosphoinositide-dependent protein kinase 1 (PDK1) regulates protease-activated receptor 4-induced platelet activation and thrombus formation through glycogen synthase kinase3beta. However, whether PDK1 also signals through the ADP receptor and its functional importance in vivo remain unknown. Objective To establish the mechanism of PDK1 in ADP-induced platelet activation and thrombosis. Methods We assessed the role of PDK1 on 2MeSADP-induced platelet activation by measuring aggregation, thromboxane generation and phosphorylation events in the presence of BX-795, which inhibits PDK1, or by using platelet-specific PDK1 knockout mice and performing western blot analysis. PDK1 function in thrombus formation was assessed with an in vivo pulmonary embolism model. Results PDK1 inhibition with BX-795 reduced 2-methylthio-ADP (2MeSADP)-induced aggregation of human and murine platelets by abolishing thromboxane generation. Similar results were observed in pdk1-/- mice. PDK1 was also necessary for the phosphorylation of mitogen activated protein kinase kinase 1/2 (MEK1/2), extracellular signal-regulated kinase 1/2, and cytosolic phospholipase A2, indicating that PDK1 regulates an upstream kinase in the mitogen-activated protein kinase (MAPK) pathway. We next determined that this upstream kinase is Raf-1, a serine/threonine kinase that is necessary for the phosphorylation of MEK1/2, as pharmacological inhibition and genetic ablation of PDK1 were sufficient to prevent Raf1 phosphorylation. Furthermore, in vivo inhibition or genetic ablation of PDK1 protected mice from collagen/epinephrine-induced pulmonary embolism. Conclusion PDK1 governs thromboxane generation and thrombosis in platelets that are stimulated with 2MeSADP by regulating activation of the MAPK pathway.

AB - Bimetallic nanoparticle encapsulation in microporous zeolite crystals is a promising route for producing catalysts with unprecedented reaction selectivities. Herein, a novel synthetic approach was developed to produce PtZnx nanoclusters encapsulated inside zeolite micropores by introducing Pt2+ cations into a zincosilicate framework via ion exchange, and subsequent controlled demetallation and alloying with framework Zn. The resulting zeolites featured nanoclusters with sizes of approximately 1 nm, having an interatomic structure corresponding to a PtZnx alloy as confirmed by pair distribution function (PDF) analysis. These materials featured simultaneous shape and substrate specificity demonstrated by the selective production of p-chloroaniline from the competitive hydrogenation of p-chloronitrobenzene and 1,3-dimethyl-5-nitrobenzene. PMID- 29575491 TI - Optimization of reprogramming culture conditions for the generation of induced pluripotent stem cells from Col1a1 4F2A-Oct4-GFP mice with high efficiency. AB - A reprogrammable transgenic mouse strain, called Col1a1 4F2A-Oct4-GFP, was bred for the present study. Because the somatic cells of this mouse strain contain only two copies of each Yamanaka factor, these animals are inefficient at producing induced pluripotent stem cells (iPSCs; approx. 0.005%) under traditional culture conditions. With an optimized culture condition, the iPSC production rate of mouse embryonic fibroblasts (MEFs) of Col1a1 4F2A-Oct4-GFP mice (MEFCol1a14F2A-Oct4-GFP ) was increased to approximately 8%. Further, promotion of cell proliferation by serum supplementation did not enhance iPSC production. Inhibition of transforming growth factor beta (TGF-beta) in the serum by SB431542 neither affected the growth rate of MEFCol1a14F2A-Oct4-GFP nor promoted iPSC production. However, the use of the gamma-irradiated STO-NEO-LIF (gammaSNL) cells to serve as feeders for iPSC production resulted in a 5-fold higher rate of iPSC production than the use of gammaMEFICR feeders. Interestingly, the use of SB431542 with the gammaMEFICR -adopted system could eliminate this difference. RT-PCR-based comparative analysis further demonstrated that TGF-beta expression was 10-fold higher in gammaMEFICR than in gammaSNL cells. Consistent with previous reports, mesenchymal to epithelial transition was found to participate in the initial steps of reprogramming in the specific context of MEFCol1a14F2A-Oct4-GFP . Moreover, we found that the initial seeding density is one of the pivotal factors for determining a high efficiency of iPSC generation. The iPSCs efficiently generated from our MEFCol1a14F2A-Oct4-GFP resembled mouse embryonic stem cells (mESCs) in aspects of teratoma formation and germline transmission. Depending on the culture conditions, our Col1a1 4F2A-Oct4 GFP mouse system can generate bona fide iPSCs with variable efficiencies, which can serve as a tool for interrogating the route taken by cells during somatic reprogramming. PMID- 29575493 TI - Duplex Healing of Selectively Thiolated Guanosine Mismatches through a Cd2+ Chemical Stimulus. AB - The on-column selective conversion of guanosine to thioguanosine (tG) yields modified oligomers that exhibit destabilisation over the fully complementary duplex. Restoration to a stabilised duplex is induced through thio-directed Cd2+ coordination; a route for healing DNA damage. Short oligomers are G-specifically thiolated through a modified on-column protocol without the need for costly thioguanosine phosphoramidites. Addition of Cd2+ ions to a duplex containing a highly disrupted tG central mismatch sequence, 3'-A6 tG4 T6 -5', suggests a (tG)8 Cd2 central coordination regime, resulting in increased base stacking and duplex stability. Equilibrium molecular dynamic calculations support the hypothesis of metal-induced healing of the thiolated duplex. The 2 nm displacement of the central tG mismatched region is dramatically reduced after the addition of a chemical stimuli, Cd2+ ions, returning to a minimized fluctuational state comparable to the unmodified fully complementary oligomer. PMID- 29575494 TI - Cortical depth profiles of luminance contrast responses in human V1 and V2 using 7 T fMRI. AB - Neural activity in early visual cortex is modulated by luminance contrast. Cortical depth (i.e., laminar) contrast responses have been studied in monkey early visual cortex, but not in humans. In addition to the high spatial resolution needed and the ensuing low signal-to-noise ratio, laminar studies in humans using fMRI are hampered by the strong venous vascular weighting of the fMRI signal. In this study, we measured luminance contrast responses in human V1 and V2 with high-resolution fMRI at 7 T. To account for the effect of intracortical ascending veins, we applied a novel spatial deconvolution model to the fMRI depth profiles. Before spatial deconvolution, the contrast response in V1 showed a slight local maximum at mid cortical depth, whereas V2 exhibited a monotonic signal increase toward the cortical surface. After applying the deconvolution, both V1 and V2 showed a pronounced local maximum at mid cortical depth, with an additional peak in deep grey matter, especially in V1. Moreover, we found a difference in contrast sensitivity between V1 and V2, but no evidence for variations in contrast sensitivity as a function of cortical depth. These findings are in agreement with results obtained in nonhuman primates, but further research will be needed to validate the spatial deconvolution approach. PMID- 29575495 TI - Wheat streak mosaic virus: a century old virus with rising importance worldwide. AB - Wheat streak mosaic virus (WSMV) causes wheat streak mosaic, a disease of cereals and grasses that threatens wheat production worldwide. It is a monopartite, positive-sense, single-stranded RNA virus and the type member of the genus Tritimovirus in the family Potyviridae. The only known vector is the wheat curl mite (WCM, Aceria tosichella), recently identified as a species complex of biotypes differing in virus transmission. Low rates of seed transmission have been reported. Infected plants are stunted and have a yellow mosaic of parallel discontinuous streaks on the leaves. In the autumn, WCMs move from WSMV-infected volunteer wheat and other grass hosts to newly emerged wheat and transmit the virus which survives the winter within the plant, and the mites survive as eggs, larvae, nymphs or adults in the crown and leaf sheaths. In the spring/summer, the mites move from the maturing wheat crop to volunteer wheat and other grass hosts and transmit WSMV, and onto newly emerged wheat in the fall to which they transmit the virus, completing the disease cycle. WSMV detection is by enzyme linked immunosorbent assay (ELISA), reverse transcription-polymerase chain reaction (RT-PCR) or quantitative RT-PCR (RT-qPCR). Three types of WSMV are recognized: A (Mexico), B (Europe, Russia, Asia) and D (USA, Argentina, Brazil, Australia, Turkey, Canada). Resistance genes Wsm1, Wsm2 and Wsm3 have been identified. The most effective, Wsm2, has been introduced into several wheat cultivars. Mitigation of losses caused by WSMV will require enhanced knowledge of the biology of WCM biotypes and WSMV, new or improved virus detection techniques, the development of resistance through traditional and molecular breeding, and the adaptation of cultural management tactics to account for climate change. PMID- 29575496 TI - Assessing canopy performance using carbonyl sulfide measurements. AB - Carbonyl sulfide (COS) is a tracer of ecosystem photosynthesis that can advance carbon cycle research from leaf to global scales; however, a range of newly reported caveats related to sink/source strength of various ecosystem components hinder its application. Using comprehensive eddy-covariance and chamber measurements, we systematically measure ecosystem contributions from leaf, stem, soil, and litter and were able to close the ecosystem COS budget. The relative contributions of nonphotosynthetic components to the overall canopy-scale flux are relatively small (~4% during peak activity season) and can be independently estimated based on their responses to temperature and humidity. Converting COS to photosynthetic CO2 fluxes based on the leaf relative uptake of COS/CO2 , faces challenges due to observed daily and seasonal changes. Yet, this ratio converges around a constant value (~1.6), and the variations, dominated by light intensity, were found unimportant on a flux-weighted daily time-scale, indicating a mean ratio of daytime gross-to-net primary productivity of ~2 in our ecosystem. The seasonal changes in the leaf relative uptake ratio may indicate a reduction in mesophyll conductance in winter, and COS-derived canopy conductance permitted canopy temperature estimate consistent with radiative skin temperature. These results support the feasibility of using COS as a powerful and much-needed means of assessing ecosystem function and its response to change.

AB - Pediatric hypertension guidelines recommend Doppler renal ultrasonography as a screening study for the evaluation of possible renal artery stenosis (RAS) in normal-weight children >= 8 years of age who are suspected of having RAS and who will cooperate with the procedure. Obese children are excluded because of technical and vascular concerns. There are no data on RI in obese children. This is a retrospective review of children aged 1.5-18 who received Doppler imaging studies over a 10-year period. A total of 174 patients were studied. There was no significant difference between the RI values based on BMI. Of the 174 individuals in the study 22 obtained follow-up CT/MRA after abnormal Doppler ultrasounds. On advanced imaging 3 were confirmed to have RAS. Obesity does not seem to influence RI.RI alone should not be used as a screening tool for RAS. An approach toward diagnosis is suggested based on BMI, renin levels, and ultrasound. PMID- 29575499 TI - Keeping secrets: Leslie E. Keeley, the gold cure and the 19th-century neuroscience of addiction. AB - BACKGROUND AND AIMS: Dr Leslie E. Keeley was perhaps the world's most famous addiction cure doctor at the turn of the 20th century, but mainstream medicine dismissed him as a quack because he dispensed a secret cure. This paper aims to describe Keeley's now largely forgotten story and to draw attention to the role of contextual issues in the acceptance or rejection of any theory of addiction, particularly the neuroscientific theories of the early 21st century. METHODS: This study is a qualitative assessment and contextualization of historical documents. Its main sources are archival and are, for the most part, unknown to historians. The paper also offers intellectual and historical context that is drawn from leading historical and sociological analyses. RESULTS: Keeley's addiction cure was dismissed as quackery because it failed to meet the changing standards of late 19th-century professional medicine. This begs us to consider contextual issues in any assertion of the viability of addiction therapeutics, in the present as well the past. CONCLUSIONS: Keeley's near erasure from the historical record was a consequence of a broader, late 19th-century medical power struggle that took precedence over the testimony of tens of thousands of satisfied patients who claimed that Keeley's cure worked. Context matters in the assessment of the viability of theories of addiction from the past, but also from the present. Historians and social scientists are well placed to make those assessments.

AB - Coralline algae are a crucial component of reef systems, stabilising reef substrate, providing habitat and contributing to accretion. Coralline algae and their surface microbial biofilms are also important as settlement cues for marine invertebrates, yet few studies address the impact of future environmental conditions on interactions between coralline algae, reef microbes and settlement by larvae of marine invertebrates. We exposed the temperate coralline algal species Amphiroa gracilis to warming and/or acidification scenarios for 21 days. Algae became bleached but photosystem II function was not measurably impacted. Settlement by larvae of the sea urchin Heliocidaris erythrogramma was reduced and the structure of the prokaryotic community associated with A. gracilis was altered. Coralline algae in ambient conditions were dominated by Alphaproteobacteria from the Rhodobacteraceae including Loktonella; those under warming were dominated by Bacteroidetes and Verrucomicrobia; acidification resulted in less Loktonella and more Planctomycetes and a combination of warming and acidification caused increases in Bacteroidetes, Verrucomicrobia and the Alphaproteobacteria family Hyphomonadaceae. These experiments indicate that predicted future environmental change may reduce the ability of some temperate reef coralline algae and associated reef microbes to facilitate settlement of invertebrate larvae as well as having a direct impact to algae via bleaching.

AB - RATIONALE: Halogenated benzoic acids occur in the environment due to their widespread agricultural and pharmaceutical use. Compound-specific stable isotope analysis (CSIA) has developed over the last decades for investigation of in situ transformation and reaction mechanisms of environmental pollutants amenable by gas chromatography (GC). As polar compounds are unsuitable for GC analysis we developed a method to perform liquid chromatography (LC)/CSIA for halogenated benzoates. METHODS: LC/isotope ratio mass spectrometry (IRMS) utilizing a LC Surveyor pump coupled to a MAT 253 isotope ratio mass spectrometer via a LC Isolink interface was applied. For chromatographic separation a YMC-Triart C18 column and a potassium hydrogen phosphate buffer (150 mM, pH 7.0, 40 degrees C, 200 MUL mL-1 ) were used, followed by wet oxidation deploying 1.5 mol L-1 ortho phosphoric acid and 200 g L-1 sodium peroxodisulfate at 75 MUL mL-1 . RESULTS: Separation of benzoate and halogenated benzoates could be achieved in less than 40 min over a concentration range of 2 orders of magnitude. Under these conditions the dehalogenation reaction of Thauera chlorobenzoica 3CB-1T using 3 chloro-, 3-bromo- and 4-chlorobenzoic acid was investigated resulting in inverse carbon isotope fractionation for meta-substituted benzoic acids and minor normal fractionation for para-substituted benzoic acids. Together with the respective growth rates this led to the assumption that dehalogenation of para-halobenzoic acids follows a different mechanism from that of meta-halobenzoic acids. CONCLUSIONS: A new LC/IRMS method for the quantitative determination of halogenated benzoates was developed and used to investigate the in vivo transformation pathways of these compounds, providing some insights into degradation and removal of these widespread compounds by T. chlorobenzoica 3CB-1T .

AB - BACKGROUND: Despite efforts in the last few decades to prevent biological invasions, agricultural pests continue to spread as a result of globalization and international trade. This study was conducted to identify suitable areas for the occurrence of four Diabrotica species and to assess the potential impact of these species in a scenario of invasion followed by spread throughout the estimated suitable regions. RESULTS: Our findings reveal that a large proportion of the suitable areas for Diabrotica species overlap with cultivated areas. Niche analyses also demonstrated that these species occupy a small proportion of the suitable habitats available to them, indicating that, if new areas are invaded, there is a risk of spread throughout adjacent regions. CONCLUSION: Most of the suitable areas for Diabrotica species overlap with highly productive agricultural areas, suggesting that a potential spread of these species may cause economic loss. Our study provides a valuable contribution to the development of tools aiming to predict the potential spread of these species throughout the world. (c) 2018 Society of Chemical Industry.

PMID- 29575504 TI - A Building Brick Principle to Create Transparent Composite Films with Multicolor Emission and Self-Healing Function. AB - A cellulose paper is used impregnated with light-emitting CdTe nanocrystals and carbon dots, and filled with a polyurethane to fabricate uniform transparent composite films with bright photoluminescence of red (R), green (G), and blue (B) (RGB) colors. A building brick-like assembly method is introduced to realize RGB multicolor emission patterns from this composite material. By sectioning out individual pixels from monochrome-emissive composite sheets, the advantage of the self-healing properties of polyurethane is taken to arrange and weld them into a RGB patterned fabric by brief exposure to ethanol. This provides an approach to form single layer RGB light-emitting pixels, such as potentially required in the display applications, without the use of any lithographic or etching processing. The method can utilize a wide range of different solution-based kinds of light emitting materials. PMID- 29575505 TI - The psychosocial impact of 22q11 deletion syndrome on patients and families: A systematic review. AB - The 22q11 deletion syndrome (22q11DS) is one of the most common genomic disorders in humans, affecting around 1:2,000 to 1: 4,000 people. 22q11DS affects multiple body systems and is associated with multiple physical problems. Given the high rate of physical morbidity associated with the 22q11DS, it was hypothesized that it would exert a high psychosocial impact on patients and their relatives. To investigate this, a systematic review of the literature and narrative synthesis was performed. Three major themes emerged. First, the complex and conflicting emotions experienced by family members resulting from the diagnosis. Second, the pervasive educational and health-care challenges associated with the diagnosis and third that people affect by 22q11DS strived for individualism. The results of this review help to inform clinical management of families with 22q11DS. PMID- 29575506 TI - Hydrido Complexes of Calcium: A New Family of Molecular Alkaline-Earth-Metal Compounds. AB - The application of solid calcium hydride CaH2 has been mostly confined to its use as a desiccant, although its catalytic activity has long been known. Since the first isolation of a well-defined molecular calcium hydride in 2006, the past decade has witnessed a gradual emergence of this new family of compounds. Although the detrimental Schlenk equilibrium has kept the number of examples low, the novelty of their reactivity, especially in small-molecule activation, holds great promise. This Minireview gives an overview of the molecular calcium hydrides reported to date, highlighting their synthesis, structure, and reactivity. PMID- 29575507 TI - Effects of clinical parameters on patient-reported outcome in cataract patients: a multicentre study. AB - PURPOSE: Ophthalmologists tend to evaluate the results of cataract surgery by focusing on the clinical visual and refractive outcomes and the incidence of complications, where patients' main interest might be their ability to perform daily activities. Therefore, there appears to be a need for optimizing effective communication between patients and ophthalmologist about the outcome of cataract surgery. The aim of this multicentre study was to determine the effects of whether the surgery was performed in one or two eyes, ocular comorbidity and per- and postoperative complications on visual function experienced by patients measured with the Catquest-9SF. METHODS: To measure patient-reported outcomes, Catquest-9SF data were collected between 2014 and 2015 in five Dutch hospitals. Data from 870 pairs of questionnaires - completed before and after cataract surgery - were compared with clinical data. Clinical data, retrieved from patients' medical files, consisted of one or two eye surgery, ocular comorbidity and per- and postoperative complications. RESULTS: Quality of vision improved more in patients who had surgery in both eyes and had fewer postoperative complications (both p < 0.001). We found a nonsignificant trend that quality of vision was worse when ocular comorbidity was present. No significant effect of peroperative complications was observed. CONCLUSION: Our results emphasize the added value of the Catquest-9SF as a tool for visual function experienced by patients; the additional information can complement clinical parameters to improve patient-centred approaches in clinical practice. PMID- 29575508 TI - Roles of pH in control of cell proliferation. AB - Precise spatiotemporal regulation of intracellular pH (pHi ) is a prerequisite for normal cell function, and changes in pHi or pericellular pH (pHe ) exert important signalling functions. It is well established that proliferation of mammalian cells is dependent on a permissive pHi in the slightly alkaline range (7.0-7.2). It is also clear that mitogen signalling in nominal absence of HCO3- is associated with an intracellular alkalinization (~0.3 pH unit above steady state pHi ), which is secondary to activation of Na+ /H+ exchange. However, it remains controversial whether this increase in pHi is part of the mitogenic signal cascade leading to cell cycle entry and progression, and whether it is relevant under physiological conditions. Furthermore, essentially all studies of pHi in mammalian cell proliferation have focused on the mitogen-induced G0-G1 transition, and the regulation and roles of pHi during the cell cycle remain poorly understood. The aim of this review is to summarize and critically discuss the possible roles of pHi and pHe in cell cycle progression. While the focus is on the mammalian cell cycle, important insights from studies in lower eukaryotes are also discussed. We summarize current evidence of links between cell cycle progression and pHi and discuss possible pHi - and pHe sensors and signalling pathways relevant to mammalian proliferation control. The possibility that changes in pHi during cell cycle progression may be an integral part of the checkpoint control machinery is explored. Finally, we discuss the relevance of links between pH and proliferation in the context of the perturbed pH homoeostasis and acidic microenvironment of solid tumours. PMID- 29575509 TI - Patient Selection by Tumor Markers in Liver Transplantation for Advanced Hepatocellular Carcinoma. AB - Although far advanced hepatocellular carcinoma (HCC) is generally considered a contraindication for liver transplantation (LT), biologically favorable tumors among them could show acceptable results. However, it is still unclear which tumors can be treated with LT. Data were collected on adult patients who underwent LT for HCC beyond the Milan criteria in 8 Korean LT centers between January 2000 and June 2013. Far advanced HCC was defined as HCC with the largest tumor >= 10 cm, 10 or more tumor nodules, or accompanying macrovascular invasion. A total of 688 patients, including 169 with far advanced HCC, were enrolled in this study. The 5-year overall and recurrence-free survival rates were 60.4% and 55.1%, respectively, for all patients but only 28.7% and 24.8%, respectively, for patients with far advanced HCC (P < 0.001). Both preoperative alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist II (PIVKA-II) were significant risk factors for HCC recurrence after LT. In particular, AFP + PIVKA II combined was a better predictor than either marker alone. Of all far advanced HCC patients with available AFP and PIVKA-II levels, 45 (30.8%) had low AFP + PIVKA-II (<=300) and their 5-year overall and recurrence-free survival rate were 47.8% and 53.4%, respectively, which were acceptable and significantly superior to those of patients with AFP (ng/mL) + PIVKA-II (nAU/mL) > 300 (21.0% and 10.8%, respectively; P < 0.001). In conclusion, patients with favorable HCC had acceptable outcomes after LT even when their tumors were extremely advanced. AFP + PIVKA-II gave reliable information about the tumor biology of far advanced HCC. Liver Transplantation 00 000-000 2018 AASLD.

AB - Intestinal T-cell lymphoma is being more frequently diagnosed in dogs owing to the wide availability of endoscopy and clonality analysis in veterinary medicine. However, no epidemiological study on intestinal T-cell lymphoma has been previously performed, and hence, information about dog breed, age and sex distributions of intestinal T-cell lymphoma has largely remained unclear. In this study, breed predisposition to canine intestinal T-cell lymphoma was determined by calculating odds ratios and 95% confidential intervals. Of the 43 breeds identified, 7 appeared to have an increased risk of developing intestinal T-cell lymphoma, including Shiba dogs, German shepherds, Cairn terriers, Boston terriers, Papillons, Pugs and Maltese. Immunohistochemistry of representative Shiba cases revealed ubiquitous cytotoxic immunophenotype in both large and small cell lymphomas. Interestingly, CD20 co-expression was observed in 11% of cases. It could potentially be aberrant expression of CD20 or neoplastic transformation of a normal subset of CD20-positive T-cells. A comparison of mean age between representative breeds revealed that Shiba dogs were slightly younger than Miniature Dachshunds (P < .05). However, there was no difference in survival between the 2 breeds. As Shiba dogs are predisposed to chronic enteropathy, there may be underlying inflammatory process contributing to lymphomagenesis of intestinal T-cell lymphoma in this breed. Our findings provide insights into the underlying pathogenesis of breed-specific canine intestinal T-cell lymphoma. PMID- 29575511 TI - Triplex Formation by Oligonucleotides Containing Organomercurated Base Moieties. AB - Homothymine oligonucleotides with a single 5-mercuricytosine or 5-mercuriuracil residue at their termini have been synthesized and their capacity to form triplexes has been examined with an extensive array of double-helical targets. UV and circular dichroism (CD) melting experiments revealed the formation and thermal denaturation of pyrimidine?purine*pyrimidine-type triple helices with all oligonucleotide combinations studied. Nearly all triplexes were destabilized upon mercuration of the 3'-terminal residue of the triplex-forming oligonucleotide, in all likelihood due to competing intramolecular HgII -mediated base pairing. Two exceptions from this general pattern were, however, observed: 5-mercuricytosine was stabilizing when placed opposite to a T?A or A?T base pair. The stabilization was further amplified in the presence of 2-mercaptoethanol (but not hexanethiol, thiophenol or cysteine), suggesting a stabilizing interaction other than HgII mediated base pairing. PMID- 29575512 TI - The role of unregulated care providers in Canada-A scoping review. AB - AIMS AND OBJECTIVES: This scoping review explored: (i) the role of unregulated care providers in the healthcare system; (ii) their potential role on interprofessional teams; (iii) the impact of unregulated care provider's role on quality of care and patient safety; and (iv) education and employment standards. BACKGROUND: Unregulated care providers in Canada assist older adults with personal support and activities of daily living in a variety of care settings. As the care needs of an aging population become increasingly complex, the role of unregulated care providers in healthcare delivery has also evolved. Currently, many unregulated care providers are performing tasks previously performed by regulated health professionals, with potential implications for quality of care and patient safety. Information is fragmented on the role, education and employment standards of unregulated care providers. METHODS: A scoping review was conducted following the methods outlined by Arksey and O'Malley (International Journal of Social Research Methodology, 8, 2005, 19) and Levac, Colquhoun, and O'Brien (Implementation Science, 5, 2010, 69). An iterative search of published and grey literature was conducted from January 2000 to September 2016 using Medline, CINAHL, SCOPUS and Google. Inclusion and exclusion criteria were applied to identify relevant studies published in English. RESULTS: The search yielded 63 papers for review. Results highlight the evolving role of unregulated care providers, a lack of recognition and a lack of authority for unregulated care provider decision-making in patient care. Unregulated care providers do not have a defined scope of practice. However, their role has evolved to include activities previously performed by regulated professionals. Variations in education and employment standards have implications for quality of care and patient safety. CONCLUSIONS: Unregulated care providers are part of an important workforce in the long-term care and community sectors in Canada. Their evolving role should be recognised and efforts made to leverage their experience on interprofessional teams and reduce variations in education and employment standards. IMPLICATIONS FOR PRACTICE: This study highlights the evolving role of unregulated care providers in Canada and presents a set of recommendations for implementation at micro, meso, and macro policy levels. PMID- 29575513 TI - Nosema ceranae in Apis mellifera: a 12 years postdetection perspective. AB - Nosema ceranae is a hot topic in honey bee health as reflected by numerous papers published every year. This review presents an update of the knowledge generated in the last 12 years in the field of N. ceranae research, addressing the routes of transmission, population structure and genetic diversity. This includes description of how the infection modifies the honey bee's metabolism, the immune response and other vital functions. The effects on individual honey bees will have a direct impact on the colony by leading to losses in the adult's population. The absence of clear clinical signs could keep the infection unnoticed by the beekeeper for long periods. The influence of the environmental conditions, beekeeping practices, bee genetics and the interaction with pesticides and other pathogens will have a direct influence on the prognosis of the disease. This review is approached from the point of view of the Mediterranean countries where the professional beekeeping has a high representation and where this pathogen is reported as an important threat. PMID- 29575514 TI - A 20-year trends in renal disease mortality in Ghana: A review of autopsies. AB - AIM: Data on the changing levels in renal morbidity and mortality are scant globally. We sought to assess trends in renal disease mortality and attributable causes over a twenty-year period in Ghana. METHODS: A retrospective analysis of 20-year autopsy records of the Pathology Departments of leading teaching hospitals in Ghana, (Korle-Bu Teaching Hospital (KBTH) in Accra and Komfo Anokye Teaching Hospital (KATH) in Kumasi) from January 1994 to December 2013. Data comprising of autopsies from in-patients, community cases and coroners' cases were used. We defined primary cause of death as death directly due to renal disease and secondary cause of death as death in which renal disease was a comorbid or contributing factor. RESULTS: Over the period, there were a total of 94,309 deaths of which 5608 were attributed to renal disease (5.9/100). Mortality rate remained fairly the same from 1994 to 2009 (5.0%), but doubled from 2010 to 2013 (10.8%). Similar trends were observed among males and females during the same period. However, males had slightly higher mortality rates (6.6%; 95% C.I. 46.1%-6.8%) compared to females (5.6%; 95% C.I. 5.4%-5.8%; p=0.271). The major leading attributable causes of renal disease death include end stage renal disease 45.0% and acute pyelonephritis accounting for 20.9% of the cases. Hypertensive heart disease accounted for 30.0% of all secondary cause of death while congestive heart disease and septicaemia accounted for 13.0% and 12.0% respectively. CONCLUSIONS: We observed marked increase in renal disease mortality rate during the last few years predominantly driven by chronic and infectious related renal diseases as main cause, and hypertensive heart disease and congestive heart failure as main secondary causes. Measures geared towards prevention, treatment and managing such conditions may impact on the reduction of renal disease mortality rate among Ghanaian populations. PMID- 29575515 TI - Conserved structural features anchor biofilm-associated RTX-adhesins to the outer membrane of bacteria. AB - Repeats-in-toxin (RTX) adhesins are present in many Gram-negative bacteria to facilitate biofilm formation. Previously, we reported that the 1.5-MDa RTX adhesin (MpIBP) from the Antarctic bacterium, Marinomonas primoryensis, is tethered to the bacterial cell surface via its N-terminal Region I (RI). Here, we show the detailed structural features of RI. It has an N-terminal periplasmic retention domain (RIN), a central domain (RIM) that can insert into the beta barrel of an outer-membrane pore protein during MpIBP secretion, and three extracellular domains at its C terminus (RIC) that transition the protein into the extender region (RII). RIN has a novel beta-sandwich fold with a similar shape to betagamma-crystallins and tryptophan RNA attenuation proteins. Because RIM undergoes fast and extensive degradation in vitro, its narrow cylindrical shape was rapidly measured by small-angle X-ray scattering before proteolysis could occur. The crystal structure of RIC comprises three tandem beta-sandwich domains similar to those in RII, but increasing in their hydrophobicity with proximity to the outer membrane. In addition, the key Ca2+ ion that rigidifies the linkers between RII domains is not present between the first two of these RIC domains. This more flexible RI linker near the cell surface can act as a 'pivot' to help the 0.6-MUm-long MpIBP sweep over larger volumes to find its binding partners. Since the physical features of RI are well conserved in the RTX adhesins of many Gram-negative bacteria, our detailed structural and bioinformatic analyses serve as a model for investigating the surface retention of biofilm-forming bacteria, including human pathogens. PMID- 29575516 TI - Diabetes impacts prediction of cirrhosis and prognosis by non-invasive fibrosis models in non-alcoholic fatty liver disease. AB - BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) patients with diabetes are at increased risk of cirrhosis and liver-related death, and thus accurate fibrosis assessment in these patients is important. We examined the ability of non-invasive fibrosis models to determine cirrhosis and outcomes in NAFLD patients with and without diabetes. METHODS: Non-alcoholic fatty liver disease patients diagnosed between 2006 and 2015 had Hepascore, NAFLD fibrosis score (NFS), APRI and FIB-4 scores calculated at baseline and were followed up for outcomes of overall and liver-related mortality/liver transplantation, hepatic decompensation and hepatocellular carcinoma (HCC). Model accuracy was determined by Harrell's C-index and by Kaplan-Meier analysis. RESULTS: A total of 284 patients (53% diabetic, 15% cirrhotic) were followed up for a median of 51.4 months, (range 6.1-146). During follow-up, diabetic patients had a greater risk of liver-related death/transplantation, HR 3.4 (95% CI 1.2-9.1) decompensation, HR 4.7 (95% CI 2.0-11.3) and HCC, HR 2.9 (95% CI 1.2-7.3). Among 241 subjects with a baseline liver biopsy, the accuracy of Hepascore, APRI and FIB-4 for predicting cirrhosis was lower amongst diabetics compared to non-diabetics (P < .005 for all). Model accuracy apart from Hepascore, was also significantly lower for predicting liver death/transplantation in patients with diabetes. No patient with a low fibrosis score and without diabetes developed liver decompensation or HCC, whereas up to 21% of diabetic patients with a low fibrosis score developed liver decompensation and up to 27% developed HCC at 5 years. CONCLUSIONS: Non invasive scoring systems are less accurate at predicting cirrhosis and liver related outcomes in patients with NAFLD and diabetes. PMID- 29575517 TI - Genetic counseling among minority populations in the era of precision medicine. AB - Precision medicine includes the use of genetic variation to determine the prevention, pathology, management, and treatment of disease, which has the potential to significantly change the practice of healthcare. As such, its success depends on (a) having reliable information about the effects of genetic variation on disease processes; and (b) the patient's understanding of their own genetic makeup such that they can use that information to affect their lifestyle and diet. Given the history of low engagement of under-represented minority populations in both clinical genetic services and genetic research, both of these aspects will be challenged and must be addressed before the benefits of precision medicine will be fully realized. Reflecting on lessons learned in the field of cancer genetic counseling, we present key issues to consider as we look forward to providing genetic counseling to minority communities in the context of precision medicine. PMID- 29575518 TI - Narrative insight in psychosis: The relationship with spiritual and religious explanatory frameworks. AB - OBJECTIVE: When considering psychosis, the concept of narrative insight has been offered as an alternative to clinical insight in determining individuals' responses to their difficulties, as it allows for a more holistic and person centred framework to be embraced within professional practice. This study aims to explore the validity of the narrative insight construct within a group of people who have experienced psychosis. DESIGN: Inductive qualitative methods were used to explore how eight participants utilized spiritual or religious explanatory frameworks for their experiences of psychosis and to consider these in relation to the construct of narrative insight. METHODS: Semi-structured interviews were undertaken with individuals who identified themselves as interested in spiritual or religious ideas and whose self-reported experiences which were identified as akin to psychosis by experienced academic clinicians. Transcriptions from these interviews were subject to interpretative phenomenological analysis within a broader research question; a selection of themes and data from the resultant phenomenological structure are explored here for their relevance to narrative insight. RESULTS: Participants discussed spiritual and biological explanations for their experiences and were able to hold alternative potential explanations alongside each other. They were reflective regarding the origins of their explanations and would describe a process of testing and proof in relation to them. CONCLUSIONS: These findings suggest that the narrative insight construct has the potential to be a valid approach to understanding experiences of psychosis, and challenge the dominance of the clinical insight construct within clinical practice. PRACTITIONER POINTS: Clinicians should value the explanatory framework for experiences which are provided by individuals experiencing psychosis, and encourage them to develop a framework which is coherent to their own world view rather than predominantly pursuing a biomedical explanation. Assessments of psychosis should be adapted to include an understanding of the cohesiveness of the individual's explanatory framework and personal value to them, with a reduced focus on their acceptance of biomedical models of 'illness'. Care and care research for individuals experiencing psychosis should consider the value of narrative insight within future developments. PMID- 29575519 TI - Presence of koilocytosis in low-grade smears of high-risk HPV-positive women is a negative predictor for cervical intraepithelial neoplasia grade 3 or more. AB - OBJECTIVE: The Netherlands converted to high-risk (hr)HPV-based screening in 2017. An increase in referral of hrHPV-positive women with low risk for cervical intraepithelial neoplasia grade 3 or more (CIN3+) is anticipated and reduction of unjustified referrals will have priority. The relevance of koilocytosis in relation to the underlying risk of high-grade CIN in a primary HPV screening setting is unclear. The aim was to investigate whether the risk for CIN3+ differs between hrHPV-positive atypical squamous cells of undetermined significance (ASC US)/low-grade squamous intraepithelial lesion (LSIL) with or without koilocytosis. METHODS: Retrospective cohort study, using data from the Dutch national pathology database (PALGA). The population was 1201 hrHPV-positive women with cytological diagnosis of ASC-US/LSIL. Reporting of koilocytosis was assessed as well as detection rates of CIN1 or less, CIN2 and CIN3+ for ASC-US/LSIL cytology stratified by presence or absence of koilocytosis. Crude and adjusted odds ratios were determined. RESULTS: Koilocytosis was present in 40.1% of ASC-US and 45.9% of LSIL cases. CIN3+ is significantly less often found when koilocytosis is present (7.8% for hrHPV-positive ASC-US with- vs 15.8% without koilocytosis). For hrHPV-positive LSIL this was 11.7% vs 20.2%. The crude and adjusted odds ratios for CIN3+ was 0.45 for hrHPV-positive ASC-US and 0.52 for hrHPV-positive LSIL. CONCLUSIONS: The presence of koilocytosis is a negative predictor of CIN3+. The risk of hrHPV-positive ASC-US with koilocytosis is in the same range as hrHPV-positive/cytology negative cases and in a setting of primary hrHPV screening these cases could be followed conservatively by repeat cytology. The results should be confirmed by the first data from the Dutch HPV-based screening programme. PMID- 29575520 TI - Sulfoximidations of Benzylic C-H bonds by Photocatalysis. AB - An efficient photocatalytic functionalization of compounds with benzylic C-H bonds by sulfoximidation in visible light is described. The mild reaction conditions allow the use of a broad array of substrates, including diarylmethane, alkyl arenes, arylacetonitrile, 2-arylacetate, and alkynyl aryl methanes. The sulfoximidation process is highly chemoselective and leads to the corresponding sulfoximines in generally good yields. Mechanistic investigations suggested the intermediacy of sulfoximidoyl radicals. PMID- 29575521 TI - Nickel Fluorocarbene Metathesis with Fluoroalkenes. AB - Alkene metathesis with directly fluorinated alkenes is challenging, limiting its application in the burgeoning field of fluoro-organic chemistry. A new nickel tris(phosphite) fluoro(trifluoromethyl)carbene complex ([P3 Ni]=CFCF3 ) reacts with CF2 =CF2 (TFE) or CF2 =CH2 (VDF) to yield both metallacyclobutane and perfluorocarbene metathesis products, [P3 Ni]=CF2 and CR2 =CFCF3 (R=F, H). The reaction of [P3 Ni]=CFCF3 with trifluoroethylene also yields metathesis products, [P3 Ni]=CF2 and cis/trans-CFCF3 =CFH. However, unlike reactions with TFE and VDF, this reaction forms metallacyclopropanes and fluoronickel alkenyl species, resulting presumably from instability of the expected metallacyclobutanes. DFT calculations and experimental evidence established that the observed metallacyclobutanes are not intermediates in the formation of the observed metathesis products, thus highlighting a novel variant of the Chauvin mechanism enabled by the disparate four-coordinate transition states. PMID- 29575522 TI - Phosphate starvation response controls genes required to synthesize the phosphate analog arsenate. AB - Environmental arsenic poisoning affects roughly 200 million people worldwide. The toxicity and mobility of arsenic in the environment is significantly influenced by microbial redox reactions, with arsenite (AsIII ) being more toxic than arsenate (AsV ). Microbial oxidation of AsIII to AsV is known to be regulated by the AioXSR signal transduction system and viewed to function for detoxification or energy generation. Here, we show that AsIII oxidation is ultimately regulated by the phosphate starvation response (PSR), requiring the sensor kinase PhoR for expression of the AsIII oxidase structural genes aioBA. The PhoRB and AioSR signal transduction systems are capable of transphosphorylation cross-talk, closely integrating AsIII oxidation with the PSR. Further, under PSR conditions, AsV significantly extends bacterial growth and accumulates in the lipid fraction to the apparent exclusion of phosphorus. This could spare phosphorus for nucleic acid synthesis or triphosphate metabolism wherein unstable arsenic esters are not tolerated, thereby enhancing cell survival potential. We conclude that AsIII oxidation is logically part of the bacterial PSR, enabling the synthesis of the phosphate analog AsV to replace phosphorus in specific biomolecules or to synthesize other molecules capable of a similar function, although not for total replacement of cellular phosphate.

The western Mexican allelic frequencies (frequency of the "C" allele = 0.18) differ from some American, East Asian and European populations. PMID- 29575525 TI - Mesoporous Hollow Sb/ZnS@C Core-Shell Heterostructures as Anodes for High Performance Sodium-Ion Batteries. AB - Combining the advantage of metal, metal sulfide, and carbon, mesoporous hollow core-shell Sb/ZnS@C hybrid heterostructures composed of Sb/ZnS inner core and carbon outer shell are rationally designed based on a robust template of ZnS nanosphere, as anodes for high-performance sodium-ion batteries (SIBs). A partial cation exchange reaction based on the solubility difference between Sb2 S3 and ZnS can transform mesoporous ZnS to Sb2 S3 /ZnS heterostructure. To get a stable structure, a thin contiguous resorcinol-formaldehyde (RF) layer is introduced on the surface of Sb2 S3 /ZnS heterostructure. The effectively protective carbon layer from RF can be designed as the reducing agent to convert Sb2 S3 to metallic Sb to obtain core-shell Sb/ZnS@C hybrid heterostructures. Simultaneously, the carbon outer shell is beneficial to the charge transfer kinetics, and can maintain the structure stability during the repeated sodiation/desodiation process. Owing to its unique stable architecture and synergistic effects between the components, the core-shell porous Sb/ZnS@C hybrid heterostructure SIB anode shows a high reversible capacity, good rate capability, and excellent cycling stability by turning the optimized voltage range. This novel strategy to prepare carbon-layer-protected metal/metal sulfide core-shell heterostructure can be further extended to design other novel nanostructured systems for high performance energy storage devices.

AB - Inhibition of fatty acid amide hydrolase (FAAH) potentiates endocannabinoid activity and is hypothesized to have therapeutic potential for mood and anxiety disorders and pain. The clinical profile of JNJ-42165279, an oral selective FAAH inhibitor, was assessed by investigating the pharmacokinetics, pharmacodynamics, safety, and binding to FAAH in the brain of healthy human volunteers. Concentrations of JNJ-42165279 (plasma, cerebrospinal fluid (CSF), urine) and fatty acid amides (FAA; plasma, CSF), and FAAH activity in leukocytes was determined in a phase I multiple ascending dose study. A positron emission tomography study with the FAAH tracer [11 C]MK3168 was conducted to determine brain FAAH occupancy after single and multiple doses of JNJ-42165279. JNJ 42165279 administration resulted in an increase in plasma and CSF FAA. Significant blocking of brain FAAH binding of [11 C]MK3168 was observed after pretreatment with JNJ-42165279. JNJ-42165279 produces potent central and peripheral FAAH inhibition. Saturation of brain FAAH occupancy occurred with doses >=10 mg of JNJ-42165279. No safety concerns were identified. PMID- 29575527 TI - Inhibition of yes-associated protein suppresses brain metastasis of human lung adenocarcinoma in a murine model. AB - Yes-associated protein (YAP) is a main mediator of the Hippo pathway and promotes cancer development and progression in human lung cancer. We sought to determine whether inhibition of YAP suppresses metastasis of human lung adenocarcinoma in a murine model. We found that metastatic NSCLC cell lines H2030-BrM3(K-rasG12C mutation) and PC9-BrM3 (EGFRDeltaexon19 mutation) had a significantly decreased p YAP(S127)/YAP ratio compared to parental H2030 (K-rasG12C mutation) and PC9 (EGFRDeltaexon19 mutation) cells (P < .05). H2030-BrM3 cells had significantly increased YAP mRNA and expression of Hippo downstream genes CTGF and CYR61 compared to parental H2030 cells (P < .05). Inhibition of YAP by short hairpin RNA (shRNA) and small interfering RNA (siRNA) significantly decreased mRNA expression in downstream genes CTGF and CYR61 in H2030-BrM3 cells (P < .05). In addition, inhibiting YAP by YAP shRNA significantly decreased migration and invasion abilities of H2030-BrM3 cells (P < .05). We are first to show that mice inoculated with YAP shRNA-transfected H2030-BrM3 cells had significantly decreased metastatic tumour burden and survived longer than control mice (P < .05). Collectively, our results suggest that YAP plays an important role in promoting lung adenocarcinoma brain metastasis and that direct inhibition of YAP by shRNA suppresses H2030-BrM3 cell brain metastasis in a murine model. PMID- 29575528 TI - Global remodeling of the mouse DNA methylome during aging and in response to calorie restriction. AB - Aging is characterized by numerous molecular changes, such as accumulation of molecular damage and altered gene expression, many of which are linked to DNA methylation. Here, we characterize the blood DNA methylome across 16 age groups of mice and report numerous global, region- and site-specific features, as well as the associated dynamics of methylation changes. Transition of the methylome throughout lifespan was not uniform, with many sites showing accelerated changes in late life. The associated genes and promoters were enriched for aging-related pathways, pointing to a fundamental link between DNA methylation and control of the aging process. Calorie restriction both shifted the overall methylation pattern and was accompanied by its gradual age-related remodeling, the latter contributing to the lifespan-extending effect. With age, both highly and poorly methylated sites trended toward intermediate levels, and aging was accompanied by an accelerated increase in entropy, consistent with damage accumulation. However, the entropy effects differed for the sites that increased, decreased and did not change methylation with age. Many sites trailed behind, whereas some followed or even exceeded the entropy trajectory and altered the developmental DNA methylation pattern. The patterns we observed in certain genomic regions were conserved between humans and mice, suggesting common principles of functional DNA methylome remodeling and its critical role in aging. The highly resolved DNA methylome remodeling provides an excellent model for understanding systemic changes that characterize the aging process.

AB - Ertugliflozin, a sodium glucose cotransporter-2 inhibitor, is approved in the United States for treatment of type 2 diabetes mellitus. A novel two-period study design with 14 C microtracer dosing in each period was used to determine absolute oral bioavailability (F) and fraction absorbed (Fa ) of ertugliflozin. Eight healthy adult men received 100-MUg i.v. 14 C-ertugliflozin (400 nCi) dose 1 h after a 15-mg oral unlabeled ertugliflozin dose (period 1), followed by 100 MUg 14 C-ertugliflozin orally along with 15 mg oral unlabeled ertugliflozin (period 2). Unlabeled ertugliflozin plasma concentrations were determined using high performance liquid-chromatography tandem mass spectrometry (HPLC-MS/MS). 14 C ertugliflozin plasma concentrations were determined using HPLC-accelerator mass spectrometry (AMS) and 14 C urine concentrations were determined using AMS. F ((area under the curve (AUC)p.o. /14 C-AUCi.v. )*(14 C-Dosei.v. /Dosep.o. )) and Fa ((14 C_Total_Urinep.o. /14 C_Total_Urinei.v. )* (14 C-Dosei.v. /14 C-Dosep.o. )) were estimated. Estimates of F and Fa were 105% and 111%, respectively. Oral absorption of ertugliflozin was complete under fasted conditions and F was ~100%. Ertugliflozin was well tolerated. PMID- 29575529 TI - Podoplanin: An emerging cancer biomarker and therapeutic target. AB - Podoplanin (PDPN) is a transmembrane receptor glycoprotein that is upregulated on transformed cells, cancer associated fibroblasts and inflammatory macrophages that contribute to cancer progression. In particular, PDPN increases tumor cell clonal capacity, epithelial mesenchymal transition, migration, invasion, metastasis and inflammation. Antibodies, CAR-T cells, biologics and synthetic compounds that target PDPN can inhibit cancer progression and septic inflammation in preclinical models. This review describes recent advances in how PDPN may be used as a biomarker and therapeutic target for many types of cancer, including glioma, squamous cell carcinoma, mesothelioma and melanoma. PMID- 29575531 TI - Metabolic potential and in situ transcriptomic profiles of previously uncharacterized key microbial groups involved in coupled carbon, nitrogen and sulfur cycling in anoxic marine zones. AB - Anoxic marine zones (AMZs) impact biogeochemical cycles at the global scale, particularly the nitrogen cycle. Key microbial players from AMZs have been identified, but the majority remains unrecognized or uncharacterized. Thirty-one single-cell amplified genomes (SAGs) from the eastern tropical North and South Pacific AMZs were sequenced to gain insight into the distribution, metabolic potential and contribution to the community transcriptional profile of these uncharacterized bacterial and archaeal groups. Detailed analyses focused on SAG bins assigned to three of these groups that presented 79%-100% estimated genome completeness: the putative sulphur-oxidizing Gamaproteobacteria EOSA II clade, a Marinimicrobia member of the recently recognized PN262000N21 clade found to be abundant in AMZ anoxic cores, and a representative of the Marine Benthic Group A Thaumarchaeota. Community-based analyses revealed that these three groups are significantly more abundant and transcriptionally more active in the AMZ microbial communities than previously described phylogenetically related microbial groups. Collectively, these groups have the potential to link biogeochemically relevant processes by coupling the carbon, nitrogen and sulfur cycles. Together, these results increase our understanding of key microbial components inhabiting AMZs and other oxygen-deficient marine environments, enhancing our capacity to predict the impact of the expansion of these ecosystems due to climate change. PMID- 29575532 TI - Printing 1D Assembly Array of Single Particle Resolution for Magnetosensing. AB - Magnetosensing is a ubiquitous ability for many organism species in nature. 1D assembly, especially that arranged in single-particle-resolution regulation, is able to sense the direction of magnetic field depending on the enhanced dipolar interaction in the linear orientation. Inspired by the magnetosome structure in magnetotactic bacteria, a 1D assembly array of single particle resolution with controlled length and well-behaved configuration is prepared via inkjet printing method assisted with magnetic guiding. In the fabrication process, chains in a "tip-to-tip" regulation with the desired number of particles are prepared in a confined tiny inkjet-printed droplet. By adjusting the receding angle of the substrate, the assembled 1D morphology is kept/deteriorated depending on the pinning/depinning behavior during ink evaporation, which leads to the formation of well-behaved 1D assembly/aggregated dot assembly. Owing to the high-aspect ratio characteristic of the assembled structure, the as-prepared 1D arrays can be used for magnetic field sensing with anisotropic magnetization M// /M? up to 6.03.

Further reduction with a mixture of potassium and [2.2.2]crypt affords the InI N-heterocyclic indyl anion [In(NONAr )]- , which crystallizes with a non-contacted [K([2.2.2]crypt)]+ cation. The indyl anion can also be isolated as the indyllithium compound In(NONAr )(Li{THF}3 ), which contains an In Li bond. Density functional theory calculations show that the HOMO of the indyl anion is a metal-centred lone pair, and preliminary reactivity studies confirm its nucleophilic behaviour. PMID- 29575534 TI - Perioperative management of children with glycogen storage disease type II-Pompe disease. AB - BACKGROUND: Pompe disease is a rare metabolic disorder caused by a deficiency of the lysosomal enzyme acid alpha-glucosidase. Glycogen accumulation damages skeletal, cardiac, and smooth muscles, causing a progressive and debilitating muscle weakness and cardiomyopathy. As life expectancy has much improved since the introduction of enzyme replacement therapy an increasing number of patients are referred for surgical procedures. Due to the potential cardiopulmonary complications, these patients form a high-risk group for the anesthesiologist. AIMS: In this study, we investigated the incidence of perioperative complications in children with Pompe disease treated in our hospital since the introduction of enzyme replacement therapy. METHODS: Anesthetic and perioperative data of children with Pompe disease treated between 1999 and 2015 in the Erasmus MC Sophia Children's Hospital, University Medical Centre, Rotterdam, The Netherlands, were collected, retrospectively. RESULTS: Of the 65 children with Pompe disease, 34 patients underwent in total 77, mostly low-risk, surgical procedures. Twenty-one children had the classic infantile form and 13 had a nonclassic presentation of Pompe disease. In 13 (16.8%) procedures, 1 or more perioperative complications occurred. Perioperative desaturation was the main complication (12.9%), followed by arrhythmia (3.8%) and heart failure requiring diuretic treatment (2.6%). One child died 2 days postoperatively, but this was considered unrelated to the procedure. CONCLUSION: Despite the potentially high anesthetic risk for children with Pompe disease under enzyme replacement therapy, the incidence of perioperative complications in our study was relatively low. Our data suggest that with proper precautionary measures and a critical choice of timing of the operation, general anesthesia in children with Pompe disease could be relatively safe nowadays. PMID- 29575535 TI - Inhibition of yes-associated protein down-regulates PD-L1 (CD274) expression in human malignant pleural mesothelioma. AB - Although tumour PD-L1 (CD274) expression had been used as a predictive biomarker in checkpoint immunotherapy targeting the PD1/PD-L1 axis in various cancers, the regulation of PD-L1 (CD274) expression is unclear. Yes-associated protein (YAP), an important oncogenic protein in Hippo signalling pathway, reportedly promotes cancer development. We investigated whether inhibition of YAP down-regulates PD L1 (CD274) in human malignant pleural mesothelioma (MPM). Western blotting showed that 2 human MPM cell lines (H2052 and 211H) had increased PD-L1 protein expression compared to H290, MS-1 and H28 cells. In H2052 and 211H cells, PD-L1 mRNA expression was significantly increased compared to other MPM cell lines; YAP knockdown by small interfering RNA decreased PD-L1 protein and mRNA expression. Forced overexpression of the YAP gene increased PD-L1 protein expression in H2452 cells. Chromatin immunoprecipitation (ChIP) assay showed the precipitation of PD L1 enhancer region encompassing 2 putative YAP-TEAD-binding sites in H2052 cells. We found that, in human MPM tissue microarray samples, YAP and PD-L1 concurrently expressed in immunohistochemistry stain (n = 70, P < .05, chi-square). We conclude that PD-L1 is correlated with YAP expression, and inhibition of YAP down regulates PD-L1 expression in human MPM. Further study of how YAP regulates PD-L1 in MPM is warranted.

PMID- 29575536 TI - Mutation analysis of adenomas and carcinomas of the colon: Early and late drivers. AB - Colorectal cancer (CRC) accounts for about 8% of all new cancer cases diagnosed in the US. We used whole exome sequence data from triplet samples (colon carcinoma, colon adenoma, and normal tissue) from 18 individuals to assess gene mutation rates. Of the 2 204 genes that were mutated, APC, TTN, TP53, KRAS, OBSCN, SOX9, PCDH17, SIGLEC10, MYH6, and BRD9 were consistent with genes being an early driver of carcinogenesis, in that they were mutated in multiple adenomas and multiple carcinomas. Fifty-two genes were mutated in >=12.5% of microsatellite stable (MSS) carcinomas but not in any of the adenomas, in line with the profile of a late driver event involved in tumor progression. Thirty eight genes were sequenced in a larger independent set of 148 carcinoma/normal tissue pairs to obtain more precise mutation frequencies. Eight of the genes, APC, TP53, ATM, CSMD3, LRP1B, RYR2, BIRC6, and MUC17, contained mutations in >20% of the carcinomas. Interestingly, mutations in four genes in addition to APC that are associated with dysregulation of Wnt signaling, were all classified as early driver events. Most of the genes that are commonly associated with colon cancer, including APC, TP53, and KRAS, were all classified as being early driver genes being mutated in both adenomas and carcinomas. Classifying genes as potential early and late driver events points to candidate genes that may help dissect pathways involved in both tumor initiation and progression.

AB - AIMS AND OBJECTIVES: To explore healthcare provider perspectives and experiences of perceived barriers and facilitators of compassion. BACKGROUND: Compassion is considered a component of quality health care that healthcare providers are increasingly expected to provide. While there have been some studies exploring facets of healthcare providers' perspectives on the barriers and facilitators to providing compassion, a comprehensive understanding based on direct reports from healthcare providers is lacking. DESIGN: Data were collected via focus groups and semi-structured interviews. Data was analyzed in accordance with Straussian grounded theory. METHODS: Semistructured focus groups with frontline healthcare providers and individual interviews with peer-nominated exemplary compassionate care providers were audio-recorded, professionally transcribed and analysed. Fifty-seven participants were recruited from three healthcare settings within both rural and urban settings in Alberta, Canada, using convenience, snowball and theoretical sampling. RESULTS: Qualitative analysis of the data generated two categories and associated themes and subthemes delineating perceived barriers and facilitators to compassion. The first category, challenges to compassion, reflects participants' discomfort associating the notion of barriers to compassion and contained several themes participants conceptualised as challenges: personal challenges, relational challenges, systemic challenges and maladaptive responses. The second category, facilitators of compassion, included the themes of personal facilitators, relational facilitators, systemic facilitators and adaptive responses of intentional action. CONCLUSION: Although participants described certain factors such as system and time constraints along with interaction styles of patients and families that can challenge healthcare provider compassion, these challenges were not considered insurmountable. While acknowledging these as challenges, participants identified healthcare providers themselves, including their responses towards the identified challenges of compassion, as significant factors in this process-a novel finding from this study. This study provides insight into healthcare providers' perspectives on the notion of barriers and facilitators in the provision of compassion. RELEVANCE TO CLINICAL PRACTICE: This study provides a blueprint for optimising compassion on a personal, relational and system level. PMID- 29575540 TI - Genomewide mechanisms of chronological longevity by dietary restriction in budding yeast. AB - Dietary restriction is arguably the most promising nonpharmacological intervention to extend human life and health span. Yet, only few genetic regulators mediating the cellular response to dietary restriction are known, and the question remains which other regulatory factors are involved. Here, we measured at the genomewide level the chronological lifespan of Saccharomyces cerevisiae gene deletion strains under two nitrogen source regimens, glutamine (nonrestricted) and gamma-aminobutyric acid (restricted). We identified 473 mutants with diminished or enhanced extension of lifespan. Functional analysis of such dietary restriction genes revealed novel processes underlying longevity by the nitrogen source quality, which also allowed us to generate a prioritized catalogue of transcription factors orchestrating the dietary restriction response. Importantly, deletions of transcription factors Msn2, Msn4, Snf6, Tec1, and Ste12 resulted in diminished lifespan extension and defects in cell cycle arrest upon nutrient starvation, suggesting that regulation of the cell cycle is a major mechanism of chronological longevity. We further show that STE12 overexpression is enough to extend lifespan, linking the pheromone/invasive growth pathway with cell survivorship. Our global picture of the genetic players of longevity by dietary restriction highlights intricate regulatory cross-talks in aging cells. PMID- 29575541 TI - Simultaneous detection of ABL1 mutation and IKZF1 deletion in Philadelphia chromosome-positive acute lymphoblastic leukemia using a customized target enrichment system panel. AB - INTRODUCTION: Recent clinical outcomes of pediatric Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ALL) vastly improved owing to tyrosine kinase inhibitor (TKI). However, the genetic status would be different in each case with ABL1 gene mutation or copy number variants (CNVs) such as IKZF1 deletion. In particular, the TKI resistant clone with ABL1 kinase mutation remains problematic. The comprehensive assessment of genetic status including mutation, insertion and deletion (indel) and CNVs is necessary. METHODS: We evaluated a next-generation sequencing (NGS)-based customized HaloPlex target enrichment system panel to simultaneously detect coding mutations, indel and CNVs. We analysed approximately 160 known genes associated with hematological disorders in 5 pediatric Ph+ALL patients. RESULTS: Mono-allelic IKZF1 deletions were found in 4 patients at diagnosis. Furthermore, the mono-allelic deletions were found in exons of RB1, EBF1, PAX5 and ETV6 genes. Bi-allelic deletions were detected in CDKN2A and CDKN2B genes in 1 patient. ABL1 mutation was also detected in 1 patient at relapse. These results were almost comparable with the results of the multiplex ligation-dependent probe amplification (MLPA) method or Sanger sequence. CONCLUSION: Next-generation sequencing-based custom HaloPlex target enrichment system panel allows us to detect the coding mutations, indel, and CNVs in pediatric Ph+ALL simultaneously, and its results seem comparable with those of other methods. PMID- 29575542 TI - The stressed brain of humans and rodents. AB - After stress, the brain is exposed to waves of stress mediators, including corticosterone (in rodents) and cortisol (in humans). Corticosteroid hormones affect neuronal physiology in two time-domains: rapid, non-genomic actions primarily via mineralocorticoid receptors; and delayed genomic effects via glucocorticoid receptors. In parallel, cognitive processing is affected by stress hormones. Directly after stress, emotional behaviour involving the amygdala is strongly facilitated with cognitively a strong emphasis on the "now" and "self," at the cost of higher cognitive processing. This enables the organism to quickly and adequately respond to the situation at hand. Several hours later, emotional circuits are dampened while functions related to the prefrontal cortex and hippocampus are promoted. This allows the individual to rationalize the stressful event and place it in the right context, which is beneficial in the long run. The brain's response to stress depends on an individual's genetic background in interaction with life events. Studies in rodents point to the possibility to prevent or reverse long-term consequences of early life adversity on cognitive processing, by normalizing the balance between the two receptor types for corticosteroid hormones at a critical moment just before the onset of puberty. PMID- 29575543 TI - Identifying Off-Label Prescriptions Through Data Mining in Danish Community Pharmacy Servers: An Exploratory Study on Desmopressin, Diclofenac, Fucidin, Mirtazapine and Quetiapine. AB - The term off-label use describes the prescription and administration of medicines outside of the terms for which it officially has been approved, including age, dose and indication. Off-label data can be generated from the Danish National Prescription Registry through combinations with diagnoses; however, the community pharmacy servers provide equal, local, albeit less data through a faster and less constrained collection process. The data collection for this exploratory study took place at five community pharmacies in Denmark. Five drugs were chosen for the investigation and collection of prescription data across a 2-year period. Off label use by age was observed to be 1.9% for diclofenac, 1.7% for desmopressin and 2.3% for quetiapine. The percentages were based on total number of 3881, 925, 2712 prescriptions, respectively. Off-label monitored by dosage appeared to be 75% for quetiapine; by box label text analysis, off-label indication was found to be 10-15% and 15-23% for quetiapine and mirtazapine (from a total number of 3178 prescriptions), respectively. By route of administration where fucidin ointment was applied to the nose in 60 patients, 83% were prescribed off-label (non dermatological). This exploratory study revealed that pharmacy servers represent a reliable and up-to-date source to collect a substantial amount of raw prescription data. The method gives straightforward and simple access to analysis of off-label use by age and dose, whereas it is possible but difficult to interpret off-label indications and route of administration from the box label text. PMID- 29575544 TI - Adverse reactions of sorafenib, sunitinib, and imatinib in treating digestive system tumors. AB - BACKGROUND: This study was conducted to assess the adverse reactions caused by multi-target tyrosine kinase inhibitor treatment of gastrointestinal tumors. METHODS: We carried out a retrospective study of drug-related adverse reactions in 115 patients who were treated with sorafenib, sunitinib, and imatinib for primary hepatocellular carcinoma or gastrointestinal stromal tumors from October 2003 to March 2012 at the Peking University International Hospital. RESULTS: The total incidence of adverse reactions of sorafenib, sunitinib, and imatinib in patients with hepatocellular carcinoma and gastrointestinal stromal tumors was > 80%. The main adverse reactions of sorafenib were hypertension in 38 patients (33.3%) and diarrhea in 28 patients (24.4%). Sunitinib was associated with higher incidence and greater grade 3-4 toxicity. The common toxicities were skin color changes in 105 patients (90.9%), hand-foot skin reactions in 65 patients (54.6%), and leukopenia (63.6%), hypertension (22.7%), proteinuria (22.7%), liver function impairment (22.7%), and hypomagnesemia (27.3%). While imatinib was well tolerated, it was associated with the highest number of adverse reactions, including skin color change (55.6%) and edema (38.9%). Hypophosphatemia (4.4%) and hoarseness (2.2%) only occurred in the sorafenib treatment group. CONCLUSIONS: The adverse reactions of multi-target tyrosine kinase inhibitor treatments are generally mild to moderate, and most patients can tolerate these without the need for further intervention. Some serious adverse reactions may be alleviated by discontinuing the drugs or by administering symptomatic treatment.

AB - Iron is an indispensable micronutrient for plant growth and development. Limited bioavailability of Fe in the soil leads to iron deficiency chlorosis in plants and yield loss. In this study, two soybean basic helix-loop-helix transcription factors, GmbHLH57 and GmbHLH300, were identified in response to Fe-deficiency. Both transcription factors are expressed in roots and nodules, and are induced by Fe deficiency; these patterns were confirmed in transgenic hairy roots expressing constructs of the endogenous promoters fused to a GUS reporter gene. Bimolecular fluorescence complementation, yeast two-hybrid and coimmunoprecipitation (co-IP) assays indicated a physical interaction between GmbHLH57 and GmbHLH300. Studies on transgenic soybeans overexpressing GmbHLH57 and GmbHLH300 revealed that overexpression of each transcription factor, alone, results in no change of the responses to Fe deficiency, whereas overexpression of both transcription factors upregulated the downstream Fe uptake genes and increased the Fe content in these transgenic plants. Compared to wild type, these double overexpression transgenic plants were more tolerant to Fe deficiency. Taken together, our findings establish that GmbHLH57 and GmbHLH300 are important transcription factors involved in Fe homeostasis in soybean. PMID- 29575547 TI - Guided maxillary sinus floor elevation using deproteinized bovine bone versus graftless Schneiderian membrane elevation with simultaneous implant placement: Randomized clinical trial. AB - OBJECTIVE: The aim of this study is to evaluate the analytical difference between the use of xenograft (control group) and graftless tenting (test group) technique after sinus lift procedure with simultaneous implant placement. MATERIALS AND METHODS: Seventeen patients and 20 sinuses where operated for sinus lift procedures using lateral window approach with simultaneous implant placement. Deproteinized bovine bone (Xenograft) was used as a filling material in control group while nongrafted sinus lifting was performed in the test group. Multislice CT was obtained preoperatively and CBCT were obtained immediately postoperative and 6 months after operation. Osstell readings were taken at the time of implant placement and implant exposure (6 months) RESULTS: Mean bone height gain in the xenograft group was 8.59 +/- 0.74 while that of the tenting group was 4.85 +/- 0.5 and it was statistically significant (P < .05). Mean bone density values in the xenograft group was 375.59 +/- 49.38 while that of the tenting group was 269.08 +/- 16.27 and it was statistically significant (P < .05). Mean ISQ values for the xenograft group was 78.3 +/- 5.08 while that of the tenting group was 74 +/- 3.19 and it was statistically significant (P < .05). CONCLUSIONS: Within the limitation of this study, sinus lift procedures with simultaneous implant placement using xenograft as a filling material or graftless technique are considered reliable procedures, however, the use of xenograft provide better results in all aspects regarding (bone height gain, bone density, and implant stability). PMID- 29575549 TI - Role of artemin in non-small cell lung cancer. AB - BACKGROUND: In this study, we investigated the role of artemin, a member of the glial cell-derived neurotrophic factor of ligands, in the malignant phenotype of lung cancer. METHODS: Artemin expression was examined in various types of lung cancer and normal lung tissues, as well as in lung cancer cell lines by immunohistochemistry and semi-quantitative PCR. Functional studies were performed using artemin overexpression or knockdown vectors in lung cancer cell lines. Methyl thiazolyl tetrazolium, flow cytometry, wound healing, and transwell assays were conducted to evaluate the contribution of artemin on tumor cell proliferation, migration, and invasion. RESULTS: Artemin is broadly expressed in lung cancer tissues, and is associated with tumor staging. Overexpression of artemin in NL9980 large cell lung cancer cells increased proliferating cells and enhanced migrating capability in wound healing and transwell assays, as well as demonstrating enhanced invasion capability. Silencing artemin in LTEP-alpha-2 adenocarcinoma cell lines decreased cellular proliferation, migration, and invasion capabilities. CONCLUSION: Artemin could promote the proliferation and invasiveness of lung cancer cells in vitro and therefore could be a new potential target to combat lung cancer. PMID- 29575548 TI - Evidence that miR-146a attenuates aging- and trauma-induced osteoarthritis by inhibiting Notch1, IL-6, and IL-1 mediated catabolism. AB - Primary osteoarthritis (OA) is associated with aging, while post-traumatic OA (PTOA) is associated with mechanical injury and inflammation. It is not clear whether the two types of osteoarthritis share common mechanisms. We found that miR-146a, a microRNA-associated with inflammation, is activated by cyclic load in the physiological range but suppressed by mechanical overload in human articular chondrocytes. Furthermore, miR-146a expression is decreased in the OA lesions of human articular cartilage. To understand the role of miR-146a in osteoarthritis, we systemically characterized mice in which miR-146a is either deficient in whole body or overexpressed in chondrogenic cells specifically. miR-146a-deficient mice develop early onset of OA characterized by cartilage degeneration, synovitis, and osteophytes. Conversely, miR-146a chondrogenic overexpressing mice are resistant to aging-associated OA. Loss of miR-146a exacerbates articular cartilage degeneration during PTOA, while chondrogenic overexpression of miR-146a inhibits PTOA. Thus, miR-146a inhibits both OA and PTOA in mice, suggesting a common protective mechanism initiated by miR-146a. miR-146a suppresses IL-1beta of catabolic factors, and we provide evidence that miR-146a directly inhibits Notch1 expression. Therefore, such inhibition of Notch1 may explain suppression of inflammatory mediators by miR-146a. Chondrogenic overexpression of miR-146a or intra-articular administration of a Notch1 inhibitor alleviates IL-1beta-induced catabolism and rescues joint degeneration in miR-146a-deficient mice, suggesting that miR-146a is sufficient to protect OA pathogenesis by inhibiting Notch signaling in the joint. Thus, miR-146a may be used to counter both aging associated OA and mechanical injury-/inflammation-induced PTOA.

AB - Nurses in mental health settings avoid talking to consumers about sexual health concerns. It is unclear whether this avoidance prevents the provision of sexual healthcare. The present study gathered information about how mental health nurses respond to sexual health issues within their routine practice, what issues they address, and their view on their role in promoting sexual health for consumers. A cross-sectional study using an electronic survey questionnaire, originally generated from a previous study in the united kingdom, was employed. The study occurred in four National Health Service Trusts in England and a national call for participants in Australia. Participants were nurse clinicians (n = 303) who self-selected by completing surveys available via email and newsletters containing links to the survey. The results demonstrated that mental health nurses do not routinely include sexual health in their practice and are poorly prepared in knowing what to do with a sexual health issue, and what services to assist consumers to use. In conclusion, it has been well established in the literature that mental health consumers experience high sexual health needs that potentially impact on health and recovery. Mental health nurses are ideally placed to promote sexual health and refer consumers to sexual health and family planning services. Training to improve the confidence and responsiveness of mental health nurses to sexual health is an urgent need.

AB - Garcinielliptone FC (GFC) is a polyisoprenylated benzophenone isolated from Platonia insignis Mart (Clusiaceae) with promising anticonvulsant properties. However, its safe use and other effects on the central nervous system require assessment. This study assessed the toxicological effects of GFC using the comet assay and the micronucleus test in mice treated for 28 days. A behavioural model was employed to detect possible injuries on the central nervous system. Mice treated with GFC (2, 10 and 20 mg/kg; i.p.) daily for 28 days were submitted to rotarod test, open-field test and tail suspension test (TST). After the behaviour tasks, biological samples were assessed to evaluate genotoxic and mutagenic effects using the comet assay and the micronucleus test. Garcinielliptone FC did not impair the performance of the animals in the rotarod and open-field tests, with no antidepressant-like effect in TST. No genotoxic effects in blood and cerebral cortex were observable in the comet assay; however, there was a significant increase in index and frequency of damage in liver after treatment with GFC 20 mg/kg. Garcinielliptone FC did not increase micronucleus frequency in bone marrow. At the tested doses, GFC was not toxic to the CNS and did not induce genotoxic damage to blood or bone narrow cells. DNA damage to liver tissue was caused only by the highest dose, although no mutagenic potential was observed.

AB - Recent metagenomic analyses have revealed a high diversity of viruses in the pelagic ocean and uncovered clear habitat-specific viral distribution patterns. Conversely, similar insights into the composition, host specificity and function of viruses associated with marine organisms have been limited by challenges associated with sampling and computational analysis. Here, we performed targeted viromic analysis of six coral reef invertebrate species and their surrounding seawater to deliver taxonomic and functional profiles of viruses associated with reef organisms. Sponges and corals' host species-specific viral assemblages with low sequence identity to known viral genomes. While core viral genes involved in capsid formation, tail structure and infection mechanisms were observed across all reef samples, auxiliary genes including those involved in herbicide resistance and viral pathogenesis pathways such as host immune suppression were differentially enriched in reef hosts. Utilising a novel OTU based assessment, we also show a prevalence of dsDNA viruses belonging to the Mimiviridae, Caudovirales and Phycodnaviridae in reef environments and further highlight the abundance of ssDNA viruses belonging to the Circoviridae, Parvoviridae, Bidnaviridae and Microviridae in reef invertebrates. These insights into coral reef viruses provide an important framework for future research into how viruses contribute to the health and evolution of reef organisms.

AB - Cutaneous aging is a complex biological process consisting of 2 elements: intrinsic aging, which is primarily determined by genetics, and extrinsic aging, which is largely caused by atmospheric factors, such as exposure to sunlight and air pollution, and lifestyle choices, such as diet and smoking. The role of the solar spectrum, comprised of ultraviolet light, specifically UVB (290-320 nm) and UVA (320-400) in causing skin damage, including skin cancers, has been well documented. In recent years, the contribution of visible light (400-700 nm) and infrared radiation (above 800 nm) in causing skin damage, similar to the photodamage caused by UV light, is also being elucidated. In addition, other atmospheric factors such as air pollution (smog, ozone, particulate matter, etc.) have been implicated in premature skin aging. The skin damage caused by environmental exposure is largely attributable to a complex cascade of reactions inside the skin initiated by the generation of reactive oxygen species (ROS), which causes oxidative damage to cellular components such as proteins, lipids, and nucleic acids. These damaged skin cells initiate inflammatory responses leading to the eventual damage manifested in chronically exposed skin. Novel therapeutic strategies to combat ROS species generation are being developed to prevent the skin damage caused by atmospheric factors. In addition to protecting skin from solar radiation using sunscreens, other approaches using topically applied ingredients, particularly antioxidants that penetrate the skin and protect the skin from within, have also been well documented. This review summarizes current knowledge of atmospheric aggressors, including UVA, UVB, visible light, infrared radiation (IR), and ozone on skin damage, and proposes new avenues for future research in the prevention and treatment of premature skin aging caused by such atmospheric factors. New therapeutic modalities currently being developed are also discussed. PMID- 29575555 TI - In vitro and in vivo effects of a novel bioactive glass-based cement used as a direct pulp capping agent. AB - Direct pulp capping is an important procedure for preserving pulp viability. The pulp capping agent must possess several properties, including usability, biocompatibility, and the ability to induce reparative dentin formation. In this study, a novel bioactive glass-based cement was examined to determine whether the cement has the necessary properties to act as a direct pulp capping agent. Physicochemical properties of the bioactive glass-based cement and in vitro effects of the cement on odontoblast-like cells, as well as in vivo effects on the exposed dental pulp, were analyzed. The cement immersed in water stabilized at pH10, and hydroxyapatite-like precipitation was induced on the surface of the cement in simulate body fluid. There were no cytotoxic effects on the viability, alkaline phosphatase activity, or calcium deposition ability of odontoblast-like cells. In the in vivo rat study of an exposed dental pulp model, the cement induced a sufficient level of reparative dentin formation by odontoblast-like cells expressing odontoblastic markers at the exposed area of the dental pulp. These results suggest that the newly developed bioactive glass-based cement provides favorable biocompatibility with the dental pulp and may be useful as a direct pulp capping agent.

PMID- 29575557 TI - Reliable sonographic features for nodal thyroglobulin to diagnose recurrent lymph node metastasis from papillary thyroid carcinoma. AB - OBJECTIVES: Ultrasound-guided aspiration cytology (US-FNAC) was previously used to diagnose lymph node metastasis of papillary thyroid carcinoma (PTC). Combined US-FNAC with nodal thyroglobulin (LN-FNA-Tg) significantly improved the diagnostic rate. However, diagnostic accuracy depends on proper node selection. Therefore, it is crucial to choose the nodes with reliable sonographic features to guide clinician for confirmation. DESIGN AND SETTING: Retrospective cohort study was carried out in one medical centre from 2011 to 2014. PARTICIPANTS: A total of 148 patients with PTC, being treated by total thyroidectomy and radioiodine, were assessed for potential nodal metastases by ultrasound. MAIN OUTCOME MEASURES: Lymph nodes with cystic content, peripheral hypervascularity, calcification, hyperechoic content, the absence of hilum and Solbiati index < 2 indicated risk of malignancy. US-FNAC and LN-FNA-Tg were both performed. Positive nodal metastasis was further confirmed by dissection. Risk impact of these sonographic features on LN-FNA-Tg to diagnose nodal metastasis was tested by logistic regression analysis based on the significance in both univariate and multivariate models. RESULTS: Overall, 49 lymph nodes were documented as recurrent nodal metastasis. LN-FNA-Tg greater than serum thyroglobulin and higher than 1 ng/mL achieved 100% of diagnostic rate for recurrent nodal metastasis. The malignant sonographic features that significantly cohered with positive LN-FNA-Tg were cystic and hyperechoic content and lack hilum, in sequence. CONCLUSIONS: LN FNA-Tg is an excellent tool to quantitatively diagnose nodal metastasis. To achieve ideal diagnosis, the most reliable sonographic features were cystic content, hyperechoic content and the absence of hilum in lymph nodes, but not calcification or Solbiati index < 2. PMID- 29575556 TI - Development of a vaccine based on bacteria-mimicking tumor cells coated with novel engineered toll-like receptor 2 ligands. AB - For a successful tumor vaccine, it is necessary to develop effective immuno adjuvants and identify specific tumor antigens. Tumor cells obtained from surgical or biopsy tissues are a good source of tumor antigens but, unlike bacteria, they do not induce strong immune responses. Here, we designed 2 novel lipopeptides that coat tumor cell surfaces and mimic bacterial components. Tumor cells coated with these lipopeptides (called bacteria-mimicking tumor cells [BMTC]) were prepared and their efficacy as a tumor vaccine examined. Natural bacterial lipopeptides act as ligands for toll-like receptor 2 (TLR2) and activate dendritic cells (DC). To increase the affinity of the developed lipopeptides for the negatively charged plasma membrane, a cationic polypeptide was connected to Pam2Cys (P2C), which is the basic structure of the TLR2 ligand. This increased the non-specific binding affinity of the peptides for the cell surface. Two such lipopeptides, P2CSK11 (containing 1 serine and 11 lysine residues) and P2CSR11 (containing 1 serine and 11 arginine residues) bound to irradiated tumor cells via the long cationic polypeptides more efficiently than the natural lipopeptide MALP2 (P2C-GNNDESNISFKEK) or a synthetic lipopeptide P2CSK4 (a short cationic polypeptide containing 1 serine and 4 lysines). BMTC coated with P2CSR11 or P2CSK11 were efficiently phagocytosed by DC and induced antigen cross-presentation in vitro. They also induced effective tumor-specific cytotoxic T cell responses and inhibited tumor growth in in vivo mouse models. P2CSR11 activated DC but induced less inflammation-inducing cytokines/interferons than other lipopeptides. Thus, P2CSR11 is a strong candidate antigen-specific immuno-adjuvant, with few adverse effects. PMID- 29575558 TI - Dispersing male Parnassius smintheus butterflies are more strongly affected by forest matrix than are females. AB - Dispersal is a central aspect of the ecology, evolution, and conservation of species. Predicting how species will respond to changing environmental conditions requires understanding factors that produce variation in dispersal. We explore one source of variation, differences between sexes within a spatial population network. Here, we compare the dispersal patterns of male and female Parnassius smintheus among 18 subpopulations over 8 years using the Virtual Migration Model. Estimated dispersal parameters differed between males and females, particularly with respect to movement through meadow and forest matrix habitat. The estimated dispersal distances of males through forest were much less than for females. Observations of female movement showed that, unlike males, females do not avoid forest nor does forest exert an edge effect. We explored whether further forest encroachment in this system would have different effects for males and females by fitting mean parameter estimates to the landscape configuration seen in 1993 and 2012. Despite differences in their dispersal due presumably to both habitat and physiological differences, males and females are predicted to respond in similar ways to reduced meadow area and increased forest isolation. PMID- 29575559 TI - Renal nerve ablation reduces blood pressure in resistant hypertension: Long-term clinical outcomes in a single-center experience. AB - Approximately 10% of patients with hypertension have resistant hypertension, even if adequate pharmacological therapy is established. In this regard, renal nerve ablation (RNA) could represent a valid alternative treatment option. In a retrospective analysis with a follow-up of 6, 12, and 24 months, the authors investigated the efficacy and safety of catheter-based renal artery ablation in 57 patients undergoing RNA with multiple renal nerve ablation in both renal arteries. In addition to medical antihypertensive therapy (4.2 +/- 1.4 drugs per patient), RNA using three different ablation systems was performed in patients with confirmed resistant hypertension (systolic blood pressure >140 mm Hg in spite of three drugs including a diuretic). The primary end point was the change in office ambulatory systolic blood pressure from baseline to 6, 12, and 24 months of follow-up after RNA. The primary safety end point was the change in plasma creatinine levels after 12 and 24 months compared with baseline. The mean office systolic blood pressure at baseline was 167.6 +/- 22.4 and after 6, 12, and 24 months averaged 143.5 +/- 21.1 (P < .05), 141.1 +/- 21.1 (P < .05), and 139.4 +/- 19.6 mm Hg (P < .05) respectively, with an average of 15.1 +/- 5.3 nerve ablations performed. No significant changes in plasma creatinine levels were observed at 12 months (P = .421) and at 24 months (P = .217). There were no complications after RNA nor any relevant adverse vascular, renal, or cardiovascular events observed except in one patient in whom a covered stent had to be placed at the femoral puncture site. In this study, in all patients with resistant hypertension, RNA, if performed adequately in the number of ablations and energy delivery, is an efficient and safe treatment option to lower office and 24-hour blood pressure. Whether these blood pressure-lowering effects will lead to a reduction of cardiovascular morbidity and mortality will require further studies. PMID- 29575561 TI - Sex-specific functional adaptation of the femoral diaphysis to body composition. AB - OBJECTIVES: The human femoral diaphysis is often used to reconstruct loading histories (mobility, activity, body mass). The proximal femur is known to be differentially affected by changes in total fat-mass (FM), fat-free mass (FFM), and body fat percentage (BF%), but the adaptation of the entire diaphysis to body composition has not been thoroughly characterized to date. Understanding how the femoral diaphysis adapts to body components would benefit biomechanical interpretations of the femoral variation and nutrition-related studies. METHODS: Combining various methods from clinical nutrition, biological anthropology, and geometric morphometrics, we evaluated the correlation of measures taken on the entire femoral diaphysis with estimated FM, FFM, and BF% from 61 CT scans (17 females, 44 males). The sample was predominantly composed of people with obesity. RESULTS: Cortical area of the cross-sections and local cortical thickness showed high correlation with BF% in particular, in females only. The curvature significantly decreased with FM and BF% in both sexes. The lowest correlations are found with FFM. CONCLUSIONS: The observed sexual dimorphism is consistent with differing aging processes; cortical bone decreases in females through endosteal resorption while it remains almost constant in males who compensate for endosteal resorption by periosteal apposition on the diaphyseal surface. The functional adaptation to compressive forces indicates a systemic endosteal apposition of bone material with increased BF% and FM in females only. FM and BF% are linked to a straighter femur in both sexes, suggesting an optimization of the resistance to compressive loads by distributing them more linearly along the entire diaphysis. PMID- 29575560 TI - Attempts to reduce alcohol intake and treatment needs among people with probable alcohol dependence in England: a general population survey. AB - AIMS: To compare the proportion of people in England with probable alcohol dependence [Alcohol Use Disorders Identification Test (AUDIT) score >= 20] with those with other drinking patterns (categorized by AUDIT scores) in terms of motivation to reduce drinking and use of alcohol support resources. DESIGN: A combination of random probability and simple quota sampling to conduct monthly cross-sectional household computer-assisted interviews between March 2014 and August 2017. SETTING: The general population in all nine regions of England. PARTICIPANTS: Participants in the Alcohol Toolkit Study (ATS), a monthly household survey of alcohol consumption among people aged 16 years and over in England (n = 69 826). The mean age was 47 years [standard deviation (SD) = 18.78; 95% confidence interval (CI) = 46.8-47] and 51% (n = 35 560) were female. MEASUREMENTS: chi2 tests were used to investigate associations with demographic variables, motivation to quit drinking, attempts to quit drinking, general practitioner (GP) engagement and types of support accessed in the last 12 months across AUDIT risk zones. FINDINGS: A total of 0.6% were classified as people with probable alcohol dependence (95% CI = 0.5-0.7). Motivation to quit (chi2 = 1692.27, P < 0.001), current attempts (chi2 = 473.94, P < 0.001) and past-year attempts (chi2 = 593.67, P < 0.001) differed by AUDIT risk zone. People with probable dependence were more likely than other ATS participants to have a past year attempt to cut down or quit (51.8%) and have received a specialist referral from their GP about drinking (13.7%), and less likely to report no motivation to reduce their drinking (26.2%). Those with probable dependence had higher use of self-help books and mobile applications (apps) than other ATS participants; however, 27.7% did not access any resources during their most recent attempt to cut down. CONCLUSIONS: Adults in England with probable alcohol dependence, measured through the Alcohol Use Disorders Identification Test, demonstrate higher motivation to quit drinking and greater use of both specialist treatment and self-driven support compared with those in other Alcohol Use Disorders Identification Test zones, but most do not access treatment resources to support their attempts. PMID- 29575562 TI - An evaluation of fetal heart rate characteristics associated with neonatal encephalopathy: a case-control study. AB - OBJECTIVE: We sought to identify fetal heart rate (FHR) characteristics that are associated with neonatal encephalopathy (NE). DESIGN: Retrospective case-control study. SETTING: A single medical centre in Shanghai, China, 2006-2015. SAMPLE: Women delivering a singleton, non-anomalous infant at >=36 weeks' gestation diagnosed with NE (cases, n = 109) were compared with a group of women with unaffected infants (controls, n = 233). METHODS: Two physicians blinded to the outcome independently reviewed FHR tracings during the last 30 minutes of tracing prior to delivery. FHR characteristics were compared in the two groups and multivariable logistic regression was used to adjust for confounding. MAIN OUTCOME MEASURES: Adjusted odds ratio (aOR) and 95% confidence interval (CI) for the presence of specific FHR categories and characteristics. RESULTS: Category II FHR tracings were observed in 89% of women prior to delivery and were not independently associated with NE. Notably, a category III FHR was observed in 17.4% of women in the NE group compared with 0.9% of women in the control group (aOR 44.99, 95% CI 7.23-279.97). Bradycardia, minimal/absent variability, late decelerations and prolonged decelerations were independently associated with NE, whereas accelerations were protective. Similar findings were found when the cases were limited to NE with arterial cord pH <7.1 and in a subgroup analysis of women with category II tracings. CONCLUSIONS: Category III tracings, while infrequent, are not uncommon prior to delivery among fetuses who develop NE. In contrast, most FHR tracings are category II prior to delivery; however, individual FHR characteristics within this category are associated with NE. FUNDING: This research was supported by the Interdisciplinary Programme of Shanghai Jiao Tong University. TWEETABLE ABSTRACT: Category III tracings are not uncommon prior to delivery among fetuses who develop neonatal encephalopathy. PMID- 29575563 TI - Orbito-frontal cortex mechanism of inhibition of return in current and remitted depression. AB - Deficient inhibition of return (IOR) for emotional materials is an important cognitive biomarker of depression. However, its neural mechanism and role in depression remission remain largely unknown. Using functional magnetic resonance imaging (fMRI), this study observed the neural foundation of inhibition of return in individuals with current (n = 30) and remitted (n = 27) depression and in healthy controls (n = 33), by using a cue-target task. The results showed that individuals with remitted depression (RMD) possessed a nonavoidant attention model for sad faces, which indicated a cue validity and was correlated with enhanced task- and resting-state activation and function connectivity in orbitofrontal cortex (OFC). The patients with major depressive disorder (MDD), in contrast, displayed an IOR effect for all faces, which indicated a strategy of attention avoidance due to the high cognitive burden in the cue-target task, and was correlated with decreased resting-state activation and function connectivity in OFC. Moreover, the hippocampus, a less-known cortex in IOR, showed a contrary model, that is, lower activation in depression remission and higher task- and resting-state activation in depressive episodes. The results suggest the OFC mechanism of the IOR effect in remitted depression and the hippocampus mechanism of the IOR effect in depressive episodes, which offer potential biomarkers for the clinical treatment of depression. PMID- 29575564 TI - Xanthomonas arboricola pv. pruni, causal agent of bacterial spot of stone fruits and almond: its genomic and phenotypic characteristics in the X. arboricola species context. AB - BACKGROUND: Xanthomonas arboricola pv. pruni (Xap) causes bacterial spot of stone fruits and almond, an important disease that may reduce the yield and vigour of the trees, as well as the marketability of affected fruits. Xap lies within the Xanthomonas genus, which has been intensively studied because of its strain specialization and host range complexity. Here, we summarize the recent advances in our understanding of the complexities of Xap, including studies of the molecular features that result after comparative phenotypic and genomic analyses, in order to obtain a clearer overview of the bacterial behaviour and infection mechanism in the context of the X. arboricola species. TAXONOMIC STATUS: Bacteria; Phylum Proteobacteria; Class Gammaproteobacteria; Order Xanthomonadales; Family Xanthomonadaceae; Genus Xanthomonas; Species X. arboricola; Pathovar pruni. HOST RANGE AND SYMPTOMS: Xap infects most Prunus species, including apricot, peach, nectarine, plum and almond, and occasionally cherry. Symptoms are found on leaves, fruits, twigs and branches or trunks. In severe infections, defoliation and fruit dropping may occur. DISTRIBUTION: Bacterial spot of stone fruits and almond is worldwide in distribution, with Xap being isolated in Africa, North and South America, Asia, Europe and Oceania. It is a common disease in geographical areas in which stone fruits and almonds are grown. Xap is listed as a quarantine organism in several areas of the world. GENOME: The genomes of six isolates from Xap have been publicly released. The genome consists of a single chromosome of around 5 000 000 bp with 65 mol% GC content and an extrachromosomal plasmid element of around 41 000 bp with 62 mol% GC content. Genomic comparative studies in X. arboricola have allowed the identification of putative virulence components associated with the infection process of bacterial spot of stone fruits and almond. DISEASE CONTROL: Management of bacterial spot of stone fruits and almond is based on an integrated approach that comprises essential measures to avoid Xap introduction in a production zone, as well as the use of tolerant or resistant plant material and chemical treatments, mainly based on copper compounds. Management programmes also include the use of appropriate cultivation practices when the disease is already established. Finally, for the effective control of the disease, appropriate detection and characterization methods are needed for use in symptomatic or asymptomatic samples as a first approach for pathogen exclusion.

PMID- 29575565 TI - Beta-peripapillary atrophy of the optic disc and its determinants in Japanese eyes: a population-based study. AB - PURPOSES: To assess beta-zone of peripapillary atrophy (beta-PPA) and its relationship between systemic and ocular factors, especially glaucoma, in a Japanese population. METHODS: Fundus photographs obtained from 2129 normal, 84 primary open-angle glaucoma (POAG) and 10 primary angle closure glaucoma subjects from 3021 participants aged 40 years or older in the Tajimi Study were analysed planimetrically. If both eyes of a subject met inclusion criteria, one eye was randomly chosen. RESULTS: The presence rates of beta-PPA were 54.7 and 77.4% (p < 0.001) and beta-PPA area averaged 0.67 and 1.06 mm2 (p < 0.001), in normal and POAG eyes, respectively. Myopia was closely related to disc ovality and beta-PPA. In normal eyes, logistic analysis showed that the presence of beta-PPA was correlated with older age, female gender, myopic refraction, thicker central corneal thickness (CCT), greater disc ovality and disc centre to fovea (disc fovea) distance and lower intraocular pressure (IOP) (p = 0.039 ~ <0.001); and multiple regression analysis showed that beta-PPA area was correlated with older age, myopic refraction, greater disc area and ovality, disc-fovea distance and lower IOP (p = 0.004 ~ <0.001) after adjusting other factors. CONCLUSIONS: The presence and size of beta-PPA in normal eyes were correlated with older age, greater disc ovality and disc-fovea distance and lower IOP. Further, its presence was associated with female gender, thicker CCT and its size with greater disc area. beta-zone of peripapillary atrophy (beta-PPA) was also associated with POAG. These results provide reference data of the beta-PPA in a Japanese population and possibly indicate clinical importance of beta-PPA in glaucoma clinic. PMID- 29575567 TI - A 16S rRNA gene sequencing and analysis protocol for the Illumina MiniSeq platform. AB - High-throughput sequencing of the 16S rRNA gene on the Illumina platform is commonly used to assess microbial diversity in environmental samples. The MiniSeq, Illumina's latest benchtop sequencer, enables more cost-efficient DNA sequencing relative to larger Illumina sequencing platforms (e.g., MiSeq). Here we used a modified custom primer sequencing approach to test the fidelity of the MiniSeq for high-throughput sequencing of the V4 hypervariable region of 16S rRNA genes from complex communities in environmental samples. To this end, we designed additional sequencing primers that enabled application of a dual-index barcoding method on the MiniSeq. A mock community was sequenced alongside the environmental samples in four different sequencing runs as a quality control benchmark. We were able to recapture a realistic richness of the mock community in all sequencing runs, and identify meaningful differences in alpha and beta diversity in the environmental samples. Furthermore, rarefaction analysis indicated diversity in many environmental samples was close to saturation. These results show that the MiniSeq can produce similar quantities of high-quality V4 reads compared to the MiSeq, yet is a cost-effective option for any laboratory interested in performing high-throughput 16S rRNA gene sequencing. PMID- 29575566 TI - Assessing glycation-mediated changes in human cortical bone with Raman spectroscopy. AB - Establishing a non-destructive method for spatially assessing advanced glycation end-products (AGEs) is a potentially useful step toward investigating the mechanistic role of AGEs in bone quality. To test the hypothesis that the shape of the amide I in the Raman spectroscopy (RS) analysis of bone matrix changes upon AGE accumulation, we incubated paired cadaveric cortical bone in ribose or glucose solutions and in control solutions for 4 and 16 weeks, respectively, at 37 degrees C. Acquiring 10 spectra per bone with a 20X objective and a 830 nm laser, RS was sensitive to AGE accumulation (confirmed by biochemical measurements of pentosidine and fluorescent AGEs). Hyp/Pro ratio increased upon glycation using either 0.1 M ribose, 0.5 M ribose or 0.5 M glucose. Glycation also decreased the amide I sub-peak ratios (cm-1 ) 1668/1638 and 1668/1610 when directly calculated using either second derivative spectrum or local maxima of difference spectrum, though the processing method (eg, averaged spectrum vs individual spectra) to minimize noise influenced detection of differences for the ribose-incubated bones. Glycation however did not affect these sub-peak ratios including the matrix maturity ratio (1668/1690) when calculated using indirect sub-band fitting. The amide I sub-peak ratios likely reflected changes in the collagen I structure. PMID- 29575568 TI - Association Between Serotonin Syndrome and Second-Generation Antipsychotics via Pharmacological Target-Adverse Event Analysis. AB - Case reports suggest an association between second-generation antipsychotics (SGAs) and serotonin syndrome (SS). The US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) was analyzed to generate hypotheses about how SGAs may interact with pharmacological targets associated with SS. FAERS was integrated with additional sources to link information about adverse events with drugs and targets. Using Proportional Reporting Ratios, we identified signals that were further investigated with the literature to evaluate mechanistic hypotheses formed from the integrated FAERS data. Analysis revealed common pharmacological targets perturbed in both SGA and SS cases, indicating that SGAs may induce SS. The literature also supported 5-HT2A antagonism and 5-HT1A agonism as common mechanisms that may explain the SGA-SS association. Additionally, integrated FAERS data mining and case studies suggest that interactions between SGAs and other serotonergic agents may increase the risk for SS. Computational analysis can provide additional insights into the mechanisms underlying the relationship between SGAs and SS. PMID- 29575570 TI - Engineering 3D Ru/Graphene Aerogel Using Metal-Organic Frameworks: Capture and Highly Efficient Catalytic CO Oxidation at Room Temperature. AB - Noble metals (Au, Pt, and Ru) loaded into carbon supports show excellent performance for CO oxidation. Herein, a tunable metal-organic framework (MOF) coating is applied to a macroscopic 3D Ru/graphene aerogel (Ru/GA) composite, using a facial step-by-step method. The open macroporous structure of the Ru/GA provides pathways for the access and diffusion of reactant and product molecules. The resulting HK (HKUST-1)-containing MOF composite exhibits good performance for CO adsorption. It can simultaneously adsorb and oxidize CO, which improves the reaction rate. In this work, the catalytic efficiency of the resulting catalyst is higher than that (~48.4%) of the Ru/GA. These findings provide a simple method for increasing the instantaneous concentration of reactants around the catalyst, which in turn increases the reaction rate. The catalytic performances of composites subjected to different pretreatment conditions are also investigated. Hopefully, this finding may provide a feasible direction for the effective management of the diverse environment issues. PMID- 29575571 TI - Tissue oximetry by diffusive reflective visible light spectroscopy: Comparison of algorithms and their robustness. AB - It is essential to measure tissue oxygen saturation (StO2 ) locally and in thin layers of tissue, for example, the bronchial mucosa, skin flaps and small bones. Visible light spectroscopy (VLS) with a shallow penetration depth is suitable method. Although several VLS algorithms have been developed and described, they have not yet been compared to each other. This hinders attempts to compare the clinical results obtained by different algorithms. To address this issue, we compared the algorithms of Harrison, Knoefel, Pittman-Duling, Sato and our OxyVLS oximeter, which applies the algorithm from Wodick and Lubbers, in a liquid phantom with optical properties of human tissue. We generally observed considerable differences between the algorithms, which were StO2 dependent. Exceptions were OxyVLS and Sato, showing a high level of agreement with negligible StO2 dependency. In spite of the considerable deviation between the other algorithms, the difference of StO2 between them in clinically normal StO2 was <10%. We did not observe any dependency of the algorithms on hemoglobin content of the phantom or temperature. PMID- 29575569 TI - Clinical, biochemical, and genetic features of four patients with short-chain enoyl-CoA hydratase (ECHS1) deficiency. AB - Short-chain enoyl-CoA hydratase (SCEH or ECHS1) deficiency is a rare inborn error of metabolism caused by biallelic mutations in the gene ECHS1 (OMIM 602292). Clinical presentation includes infantile-onset severe developmental delay, regression, seizures, elevated lactate, and brain MRI abnormalities consistent with Leigh syndrome (LS). Characteristic abnormal biochemical findings are secondary to dysfunction of valine metabolism. We describe four patients from two consanguineous families (one Pakistani and one Irish Traveler), who presented in infancy with LS. Urine organic acid analysis by GC/MS showed increased levels of erythro-2,3-dihydroxy-2-methylbutyrate and 3-methylglutaconate (3-MGC). Increased urine excretion of methacrylyl-CoA and acryloyl-CoA related metabolites analyzed by LC-MS/MS, were suggestive of SCEH deficiency; this was confirmed in patient fibroblasts. Both families were shown to harbor homozygous pathogenic variants in the ECHS1 gene; a c.476A > G (p.Gln159Arg) ECHS1variant in the Pakistani family and a c.538A > G, p.(Thr180Ala) ECHS1 variant in the Irish Traveler family. The c.538A > G, p.(Thr180Ala) ECHS1 variant was postulated to represent a Canadian founder mutation, but we present SNP genotyping data to support Irish ancestry of this variant with a haplotype common to the previously reported Canadian patients and our Irish Traveler family. The presence of detectable erythro-2,3-dihydroxy-2 methylbutyrate is a nonspecific marker on urine organic acid analysis but this finding, together with increased excretion of 3-MGC, elevated plasma lactate, and normal acylcarnitine profile in patients with a Leigh-like presentation should prompt consideration of a diagnosis of SCEH deficiency and genetic analysis of ECHS1. ECHS1 deficiency can be added to the list of conditions with 3-MGA. PMID- 29575572 TI - Functional expansion pharyngoplasty: Technical update by unidirectional barbed sutures.

PMID- 29575575 TI - Endostar (rh-endostatin) versus placebo in combination with vinorelbine plus cisplatin chemotherapy regimen in treatment of advanced non-small cell lung cancer: A meta-analysis. AB - BACKGROUND: This meta-analysis was conducted to investigate the efficacy and safety of Endostar (rh-endostatin) versus a placebo in combination with a vinorelbine plus cisplatin (NP) chemotherapy regimen for the treatment of advanced non-small cell lung cancer (NSCLC). METHODS: Two reviewers independently searched Medline, PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, ASCO, ESMO, the Web of Science, and CNKI databases to locate relevant controlled clinical trials. The treatment efficacy and drug-related toxicity of NP + Endostar (NPE) and NP groups were pooled through meta-analysis according to random or fixed effect models. RESULTS: Fifteen prospective clinical studies were included in this meta-analysis. The pooled risk ratio (RR) for objective response rate was 1.74 (95% confidence interval [CI] 1.43-2.11); the objective response rate in the NPE group was significantly higher than in the NP group (P < 0.05). Nine publications evaluated the incidence of leucopenia between Endostar versus a placebo in combination with an NP chemotherapy regimen. The pooled results showed no statistically significant difference between NPE and NP chemotherapy regimens for leucopenia, thrombocytopenia, and nausea/vomiting risk (P > 0.05). The one-year survival rate in the NPE group was higher than in the NP group, with a statistically significant difference (RR = 1.70, 95% CI 1.07-2.89; P < 0.05). CONCLUSION: Endostar combined with an NP chemotherapy regimen can improve the prognosis of patients with advanced NSCLC without increasing the risk of toxicity. PMID- 29575576 TI - The mitochondrial unfolded protein response is activated upon hematopoietic stem cell exit from quiescence. AB - The mitochondrial unfolded protein response (UPRmt ), a cellular protective program that ensures proteostasis in the mitochondria, has recently emerged as a regulatory mechanism for adult stem cell maintenance that is conserved across tissues. Despite the emerging genetic evidence implicating the UPRmt in stem cell maintenance, the underlying molecular mechanism is unknown. While it has been speculated that the UPRmt is activated upon stem cell transition from quiescence to proliferation, the direct evidence is lacking. In this study, we devised three experimental approaches that enable us to monitor quiescent and proliferating hematopoietic stem cells (HSCs) and provided the direct evidence that the UPRmt is activated upon HSC transition from quiescence to proliferation, and more broadly, mitochondrial integrity is actively monitored at the restriction point to ensure metabolic fitness before stem cells are committed to proliferation. PMID- 29575578 TI - Direct-Patterning SWCNTs Using Dip Pen Nanolithography for SWCNT/Silicon Solar Cells. AB - Dip pen nanolithography (DPN) is used to pattern single-walled carbon nanotube (SWCNT) lines between the n-type Si and SWCNT film in SWCNT/Si solar cells. The SWCNT ink composition, loading, and DPN pretreatment are optimized to improve patterning. This improved DPN technique is then used to successfully pattern >1 mm long SWCNT lines consistently. This is a 20-fold increase in the previously reported direct-patterning of SWCNT lines using the DPN technique, and demonstrates the scalability of the technique to pattern larger areas. The degree of the uniformity of SWCNTs in these lines is further characterized by Raman spectroscopy and scanning electron microscopy. The patterned SWCNT lines are used as thin conductive pathways in SWCNT/Si solar cells, similar to front contact electrodes. The critical parameters of these solar cells are measured and compared to control cells without SWCNT lines. The addition of SWCNT lines increases power conversion efficiency by 40% (relative). Importantly, the SWCNT lines reduce average series resistance by 44%, and consequently increase average fill factor by 24%.

AB - To maintain iron homoeostasis, the iron regulatory hormone hepcidin is tightly controlled by BMP-Smad signalling pathway, but the physiological role of Smad7 in hepcidin regulation remains elusive. We generated and characterized hepatocyte specific Smad7 knockout mice (Smad7Alb/Alb ), which showed decreased serum iron, tissue iron, haemoglobin concentration, up-regulated hepcidin and increased phosphor-Smad1/5/8 levels in both isolated primary hepatocytes and liver tissues. Increased levels of hepcidin lead to reduced expression of intestinal ferroportin and mild iron deficiency anaemia. Interestingly, we found no difference in hepcidin expression or phosphor-Smad1/5/8 levels between iron-challenged Smad7Alb/Alb and Smad7flox/flox , suggesting other factors assume the role of iron-induced hepcidin regulation in Smad7 deletion. We performed RNA-seq to identify differentially expressed genes in the liver. Significantly up-regulated genes were then mapped to pathways, revealing TGF-beta signalling as one of the most relevant pathways, including the up-regulated genes Smad6, Bambi and Fst (Follistatin). We found that Smad6 and Bambi-but not Follistatin-are controlled by the iron-BMP-Smad pathway. Overexpressing Smad6, Bambi or Follistatin in cells significantly reduced hepcidin expression. Smad7 functions as a key regulator of iron homoeostasis by negatively controlling hepcidin expression, and Smad6 and Smad7 have non-redundant roles. Smad6, Bambi and Follistatin serve as additional inhibitors of hepcidin in the liver. PMID- 29575579 TI - Continuing Professional Development. PMID- 29575580 TI - Editorial Profiles.

PMID- 29575583 TI - Global effects of plant litter alterations on soil CO2 to the atmosphere. AB - Soil respiration (Rs) is the largest terrestrial carbon (C) efflux to the atmosphere and is predicted to increase drastically through global warming. However, the responses of Rs to global warming are complicated by the fact that terrestrial plant growth and the subsequent input of plant litter to soil are also altered by ongoing climate change and human activities. Despite a number of experiments established in various ecosystems around the world, it remains a challenge to predict the magnitude and direction of changes in Rs and its temperature sensitivity (Q10 ) due to litter alteration. We present a meta analysis of 100 published studies to examine the responses of Rs and Q10 to manipulated aboveground and belowground litter alterations. We found that 100% aboveground litter addition (double litter) increased Rs by 26.1% (95% confident intervals, 18.4%-33.7%), whereas 100% aboveground litter removal, root removal and litter + root removal reduced Rs by 22.8% (18.5%-27.1%), 34.1% (27.2%-40.9%) and 43.4% (36.6%-50.2%) respectively. Moreover, the effects of aboveground double litter and litter removal on Rs increased with experimental duration, but not those of root removal. Aboveground litter removal marginally increased Q10 by 6.2% (0.2%-12.3%) because of the higher temperature sensitivity of stable C substrate than fresh litter. Estimated from the studies that simultaneously tested the responses of Rs to aboveground litter addition and removal and assuming negligible changes in root-derived Rs, "priming effect" on average accounted for 7.3% (0.6%-14.0%) of Rs and increased over time. Across the global variation in terrestrial ecosystems, the effects of aboveground litter removal, root removal, litter + root removal on Rs as well as the positive effect of litter removal on Q10 increased with water availability. Our meta-analysis indicates that priming effects should be considered in predicting Rs to climate change-induced increases in litterfall. Our analysis also highlights the need to incorporate spatial climate gradient in projecting long-term Rs responses to litter alterations. PMID- 29575584 TI - The effect of implant-abutment junction position on crestal bone loss: A systematic review and meta-analysis. AB - PURPOSE: To investigate the effect of the apico-coronal implant position on early and late crestal bone loss (CBL), in bone and tissue level implants. MATERIALS AND METHODS: Electronic and manual literature searches were conducted for controlled clinical trials reporting on CBL before and after functional loading of implants. Random effects meta-analyses were applied to analyze the weighted mean difference (WMD) and meta-regression was conducted to investigate any potential influences of select confounding factors. RESULTS: Fourteen articles were included in the systematic review and 12 were included in the quantitative synthesis. For bone level implants, WMD comparing early CBL in equi and subcrestal placement was 0.15 mm (P = .18). For analyses of late CBL in bone level implants, equi and subcrestal placement revealed a 0.03 mm WMD (P = .88). Where in supra and subcrestal placement, WMD was 0.04 mm (P = .86). The comparison presented considerable heterogeneity between these two arms, where the P value for chi-square test presented as .006. Finally, for CBL between supra and equicrestal placement, WMD was -0.64 mm (P < .0001), favoring the supracrestal group. For tissue level implants, WM of early and late CBL in implants placed equi-crestally was 0.68 +/- 0.12 mm and 0.69 +/- 0.54 mm, respectively, where for implants placed sub-crestally, the WM of CBL was 1.72 +/- 0.15 mm and 2.26 +/- 0.63 mm, respectively. CONCLUSION: Within the limitations of this study, it is recommended to place tissue level implants equicrestally, and bone level implants subcrestally. PMID- 29575585 TI - Clinical genetic counselors: An asset in the era of precision medicine. AB - Trying to predict what genetic counseling will look like in the era of precision medicine is a continuous challenge. According to the National Institutes of Health, precision medicine is an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle. In order to explore the future of genetic counseling practice in this era, this article examines the current genetic counseling practice, internal and external forces that most likely will continue to shape the genetic counseling profession, and discusses the most important aspects of what genetic counselors have to offer in the era of precision medicine. PMID- 29575586 TI - Correlation between observation task performance and visual acuity, contrast sensitivity and environmental light in a simulated maritime study. AB - PURPOSE: To examine the relevance of visual acuity (VA) and index of contrast sensitivity (ICS) as predictors for visual observation task performance in a maritime environment. METHODS: Sixty naval cadets were recruited to a study on observation tasks in a simulated maritime environment under three different light settings. Their ICS were computed based on contrast sensitivity (CS) data recorded by Optec 6500 and CSV-1000E CS tests. The correlation between object identification distance and VA/ICS was examined by stepwise linear regression. RESULTS: The object detection distance was significantly correlated to the level of environmental light (p < 0.001), but not to the VA or ICS recorded in the test subjects. Female cadets had a significantly shorter target identification range than the male cadets. CONCLUSION: Neither CS nor VA were found to be significantly correlated to observation task performance. This apparent absence of proven predictive value of visual parameters for observation tasks in a maritime environment may presumably be ascribed to the normal and uniform visual capacity in all our study subjects. PMID- 29575588 TI - Exercise on-transition uncoupling of ventilatory, gas exchange and cardiac hemodynamic kinetics accompany pulmonary oxygen stores depletion to impact exercise intolerance in human heart failure. AB - AIM: In contrast to knowledge that heart failure (HF) patients demonstrate peak exercise uncoupling across ventilation, gas exchange and cardiac haemodynamics, whether this dyssynchrony follows that at the exercise on-transition is unclear. This study tested whether exercise on-transition temporal lag for ventilation relative to gas exchange and oxygen pulse (O2 pulse) couples with effects from abnormal pulmonary gaseous oxygen store (O2store ) contributions to VO2 to interdependently precipitate persistently elevated ventilatory demand and low oxidative metabolic capacity in HF. METHODS: Beat-to-beat HR and breath-to-breath ventilation and gas exchange were continuously acquired in HF (N = 9, ejection fraction = 30 +/- 9%) and matched controls (N = 10) during square-wave ergometry at 60% VO2peak (46 +/- 14 vs 125 +/- 54-W, P < .001). Temporal responses across VE , VO2 and O2 pulse were assessed for the exercise on-transition using single exponential model Phase II on-kinetic time constants (tau = time to reach 63% steady-state rise). Breath-to-breath gas fractions and respiratory flows were used to determine O2stores . RESULTS: HF vs controls: tau for VE (137 +/- 93 vs 74 +/- 40-seconds, P = .03), VO2 (60 +/- 40 vs 23 +/- 5-seconds, P = .03) and O2 pulse (28 +/- 18 vs 23 +/- 15-seconds, P = .59). Within HF, tau for VE differed from O2 pulse (P < .02), but not VO2 . Exercise VE rise (workload indexed) differed in HF vs controls (545 +/- 139 vs 309 +/- 88-mL min-1 W-1 , P < .001). Exercise on-transition O2store depletion in HF exceeded controls, generally persisting to end-exercise. CONCLUSION: These data suggest HF demonstrated exercise on-transition O2store depletion (high O2store contribution to VO2 ) coupled with dyssynchronous VE , VO2 and O2 pulse kinetics-not attributable to prolonged cardiac haemodynamics. Persistent high ventilatory demand and low oxidative metabolic capacity in HF may be precipitated by physiological uncoupling occurring within the exercise on-transition. PMID- 29575587 TI - Outcomes of Patients With Syncope and Suspected Dementia. AB - OBJECTIVES: Syncope and near-syncope are common in patients with dementia and a leading cause of emergency department (ED) evaluation and subsequent hospitalization. The objective of this study was to describe the clinical trajectory and short-term outcomes of patients who presented to the ED with syncope or near-syncope and were assessed by their ED provider to have dementia. METHODS: This multisite prospective cohort study included patients 60 years of age or older who presented to the ED with syncope or near-syncope between 2013 and 2016. We analyzed a subcohort of 279 patients who were identified by the treating ED provider to have baseline dementia. We collected comprehensive patient-level, utilization, and outcomes data through interviews, provider surveys, and chart abstraction. Outcome measures included serious conditions related to syncope and death. RESULTS: Overall, 221 patients (79%) were hospitalized with a median length of stay of 2.1 days. A total of 46 patients (16%) were diagnosed with a serious condition in the ED. Of the 179 hospitalized patients who did not have a serious condition identified in the ED, 14 (7.8%) were subsequently diagnosed with a serious condition during the hospitalization, and an additional 12 patients (6.7%) were diagnosed postdischarge within 30 days of the index ED visit. There were seven deaths (2.5%) overall, none of which were cardiac-related. No patients who were discharged from the ED died or had a serious condition in the subsequent 30 days. CONCLUSIONS: Patients with perceived dementia who presented to the ED with syncope or near-syncope were frequently hospitalized. The diagnosis of a serious condition was uncommon if not identified during the initial ED assessment. Given the known iatrogenic risks of hospitalization for patients with dementia, future investigation of the impact of goals of care discussions on reducing potentially preventable, futile, or unwanted hospitalizations while improving goal-concordant care is warranted. PMID- 29575589 TI - Clinical and esthetic outcome with immediate insertion and provisionalization with or without connective tissue grafting in presence of mucogingival recessions: A retrospective analysis with follow-up between 1 and 8 years. AB - BACKGROUND: Recessions following immediate implant insertion are frequently reported in the literature. Data regarding implant installation in presence of mucogingival recessions are rare. PURPOSE: This study observes soft tissue level changes following immediate implant insertion and provisionalization of implants with or without connective tissue grafts in the anterior maxilla in patients with initial mucogingival recession within a follow-up period between one and eight years. MATERIALS AND METHODS: Twenty-six patients with marginal gingival recessions, which were designated for extraction and immediate implant insertion in the anterior zone of the maxilla (13-23), were included. Out of a larger group of immediate implants only single tooth replacements with 1 to 3 mm recession and a pre- and post-op CB-CT were selected. Facial bone deficiencies were grafted flaplessly with autologous bone in all sites. In a group of 13 patients the recessions (mean 2.3 +/- 0.7 mm, range 1.0-3.0 mm) were grafted additionally by connective tissue (ABG + CTG), in the remaining 13 patients no soft tissue grafting (mean recession 1.8 +/- 0.6 mm, range 1.0-3.0 mm) was performed (ABG). The marginal hard and soft tissue level, the width of the keratinized mucosa, the PES, and implant success were evaluated. RESULTS: After a mean follow-up period of 45 months the recessions were significantly reduced in the ABG group from 1.8 to 0.9 mm. The improvement was even more pronounced in the ABG + CTG group (from 2.3 to 0.5 mm). The PES improved significantly in both groups. At final examination all implants were still in function. Within the observational period, in 5 of 13 implants a marginal bone loss of more than 1 mm was noticed in the ABG, but in none of the ABG + CTG group. CONCLUSIONS: These clinical results provide evidence that immediate implant placement might improve the facial soft tissue level. This was more evident in cases with a greater recession and an additional treatment with connective tissue grafts. PMID- 29575591 TI - Improved clonality detection in Hodgkin lymphoma using a semi-nested modification of the BIOMED-2 PCR assay for IGH and IGK rearrangements: A paraffin-embedded tissue study. AB - The BIOMED-2 PCR protocols targeting IGH and IGK genes may be useful for detecting clonality in Hodgkin lymphoma (HL). The clonality detection rates, however, have not been very high with these methods using paraffin-embedded tumor sections. We previously described the usefulness of the semi-nested BIOMED-2 IGH assay in B-cell malignancies. In this study, we devised a novel semi-nested BIOMED-2 IGK assay. Employing 58 cases of classical HL, we carried out the standard BIOMED-2, BIOMED-2 followed by BIOMED-2 re-amplification, and BIOMED-2 followed by semi-nested BIOMED-2, all targeting IGH and IGK, using paraffin embedded tissues. In both IGH and IGK assays, semi-nested assays yielded significantly higher clonality detection rates than the standard assays and re amplification assays. Clonality was detected in 13/58 (22.4%) classical HL cases using the standard IGH/IGK assays while it was detected in 38/58 (65.5%) cases using semi-nested IGH/IGK assays. The detection rates were not associated with the HL subtypes, CD30-positive cell density, CD20-positive cell density, or Epstein-Barr virus (EBV) positivity. In conclusion, tumor clonality was detected in nearly two-thirds of classical HL cases using semi-nested BIOMED-2 IGH/IGK assays using paraffin tumor sections. These semi-nested assays may be useful when the standard IGH/IGK assays fail to detect clonality in histopathologically suspected HLs. PMID- 29575590 TI - Resistance to discontinuing breast cancer screening in older women: A qualitative study. AB - OBJECTIVE: Screening mammography is associated with reduced breast cancer specific mortality; however, among older women, evidence suggests that the potential harms of screening may outweigh the benefits. We used a qualitative approach to examine the willingness of older women from different racial/ethnic groups to discontinue breast cancer screening. METHODS: Women >=70 years of age who reported having a screening mammogram in the past 3 years and/or reported that they intended to continue screening in the future were recruited for in depth interviews. Participants who intended to continue screening were asked to describe how the following hypothetical scenarios would impact a decision to discontinue screening: health concerns or limited life expectancy, a physician's recommendation to discontinue, reluctance to undergo treatment, and recommendations from experts or governmental panels to stop screening. Semi structured, face-to-face interviews were audio-recorded. Data coding and analysis followed inductive and deductive approaches. RESULTS: Regardless of the scenario, participants (n = 29) expressed a strong intention to continue screening. Based on the hypothetical physician recommendations, intentions to continue screening appeared to remain strong. They did not envision a change in their health status that would lead them to discontinue screening and were skeptical of expert/government recommendations. There were no differences observed according to age, race/ethnicity, or education. CONCLUSIONS: Among older women who planned to continue screening, intentions to continue breast cancer screening appear to be highly resilient and resistant to recommendations from physicians or expert/government panels. PMID- 29575592 TI - Connectivity of the ventral visual cortex is necessary for object recognition in patients. AB - The functional profiles of regions in the ventral occipital-temporal cortex (VTC), a critical region for object visual recognition, are associated with the VTC connectivity patterns to nonvisual regions relevant to the corresponding object domain. However, whether and how whole-brain connections affect recognition behavior remains untested. We directly examined the necessity of VTC connectivity in object recognition behavior by testing 82 patients whose lesion spared relevant VTC regions but affected various white matter (WM) tracts and other regions. In these patients, we extracted the whole-brain anatomical connections of two VTC domain-selective (large manmade objects and animals) clusters with probabilistic tractography, and examined whether such connectivity pattern can predict recognition performance of the corresponding domains with support vector regression (SVR) analysis. We found that the whole-brain anatomical connectivity of large manmade object-specific cluster successfully predicted patients' large object recognition performance but not animal recognition or control tasks, even after we excluded connections with early visual regions. The contributing connections to large object recognition included tracts between VTC-large object cluster and distributed regions both within and beyond the visual cortex (e.g., putamen, superior, and middle temporal gyrus). These results provide causal evidence that the VTC whole-brain anatomical connectivity is necessary for at least certain domains of object recognition behavior. PMID- 29575593 TI - Utility of autopsy brain imprint and squash cytology for detection of lymphoma/leukemia emboli in select patients presenting with rapid decline in mental status. AB - Central nervous system (CNS) hematologic malignancies, whether primary or secondary, are uncommon and their clinical presentations vary. Intravascular lymphoma (IVL) is a very rare, aggressive systemic malignancy that is often difficult to diagnose and susceptible to early CNS involvement. Blast crisis in myeloid leukemias can cause widespread neoplastic emboli. Here, we report two adult patients (72 years and 22 years of age) who presented with altered mental status followed by rapid decline in their conditions leading to death. No prior significant medical history was present for either patient, while acute myeloid leukemia was diagnosed in the younger patient immediately before death. During autopsy, we performed imprint and squash preparations, and frozen sections of representative cerebral cortex, cerebellum, leptomeninges, and the pituitary gland. In the older patient, presence of IVL was readily detected on cytologic preparations. Diffuse involvement of brain vasculature and perivascular parenchyma with acute myeloid leukemia was identified in the other patient. Although examination of the fresh brain is not routinely performed during autopsy, these cases are presented to illustrate that imprint and squash preparations can provide a rapid and reliable provisional autopsy diagnosis in select patients. PMID- 29575594 TI - Preoperative weight loss program involving a 20-day very low-calorie diet for obesity before laparoscopic gastrectomy for gastric cancer. AB - INTRODUCTION: The increased visceral fat in patients with obesity can increase the technical difficulty of surgery. This study was performed to evaluate a preoperative 20-day very low-calorie diet for obesity before laparoscopic gastrectomy for gastric cancer. METHODS: This prospective single-center study involved patients with obesity who were planning to undergo laparoscopic gastrectomy for gastric cancer. Obesity was defined according to the Japanese criteria: BMI >=25 kg/m2 or waist circumference >=85 cm in men and >=90 cm in women. The patients underwent a preoperative 20-day very low-calorie diet and received nutritional counseling. Weight loss, body composition, visceral fat mass, and operative outcomes were evaluated. RESULTS: Thirty-three patients were enrolled from September 2013 to August 2015. Their median age was 71 years, and 78.8% were men. Their median bodyweight and BMI were 72.3 kg (range, 53.8-82.5 kg) and 26.0 kg/m2 (range, 23.5-31.0 kg/m2 ), respectively. The patients achieved a mean weight loss of 4.5% (95% confidence interval [CI]: 3.8-5.1), corresponding to 3.2 kg (95%CI: 2.7-3.7 kg). Body fat mass was significantly decreased by a mean of 2.5 kg (95%CI: 1.9-3.1), whereas skeletal muscle mass was unaffected (mean: -0.20 kg [95%CI: -0.55-0.15]). The visceral fat mass reduction rate was high as 16.8% (range, 11.6%-22.0%). All patients underwent laparoscopic gastrectomy as planned. Severe postoperative morbidity (Clavien-Dindo grade >=III) was seen in only one patient (3.0%). CONCLUSION: The preoperative 20-day very low-calorie diet weight loss program is promising for the treatment of obesity before laparoscopic gastrectomy for gastric cancer. PMID- 29575595 TI - Ultraviolet Photoluminescence of Carbon Nanospheres and its Surface Plasmon Induced Enhancement. AB - Ultraviolet (UV) light can be used in versatile applications ranging from photoelectronic devices to biomedical imaging. In the development of new UV light sources, in this study, stable UV emission at ~350 nm is unprecedentedly obtained from carbon nanospheres (CNSs). The origin of the UV fluorescence is comprehensively investigated via various characterization methods, including Raman and Fourier transform infrared analyses, with comparison to the visible emission of carbon nanodots. Based on the density functional calculations, the UV fluorescence is assigned to the carbon nanostructures bonded to bridging O atoms and dangling -OH groups. Moreover, a twofold enhancement in the UV emission is acquired for Au-carbon core-shell nanospheres (Au-CNSs). This remarkable modification of the UV emission is primarily ascribed to charge transfer between the CNSs and the Au surface. PMID- 29575574 TI - No effects without causes: the Iron Dysregulation and Dormant Microbes hypothesis for chronic, inflammatory diseases. AB - Since the successful conquest of many acute, communicable (infectious) diseases through the use of vaccines and antibiotics, the currently most prevalent diseases are chronic and progressive in nature, and are all accompanied by inflammation. These diseases include neurodegenerative (e.g. Alzheimer's, Parkinson's), vascular (e.g. atherosclerosis, pre-eclampsia, type 2 diabetes) and autoimmune (e.g. rheumatoid arthritis and multiple sclerosis) diseases that may appear to have little in common. In fact they all share significant features, in particular chronic inflammation and its attendant inflammatory cytokines. Such effects do not happen without underlying and initially 'external' causes, and it is of interest to seek these causes. Taking a systems approach, we argue that these causes include (i) stress-induced iron dysregulation, and (ii) its ability to awaken dormant, non-replicating microbes with which the host has become infected. Other external causes may be dietary. Such microbes are capable of shedding small, but functionally significant amounts of highly inflammagenic molecules such as lipopolysaccharide and lipoteichoic acid. Sequelae include significant coagulopathies, not least the recently discovered amyloidogenic clotting of blood, leading to cell death and the release of further inflammagens. The extensive evidence discussed here implies, as was found with ulcers, that almost all chronic, infectious diseases do in fact harbour a microbial component. What differs is simply the microbes and the anatomical location from and at which they exert damage. This analysis offers novel avenues for diagnosis and treatment. PMID- 29575596 TI - Verification of Acuros XB dose algorithm using 3D printed low-density phantoms for clinical photon beams. AB - The transport-based dose calculation algorithm Acuros XB (AXB) has been shown to accurately account for heterogeneities primarily through comparisons with Monte Carlo simulations. This study aims to provide additional experimental verification of AXB for clinically relevant flattened and unflattened beam energies in low density phantoms of the same material. Polystyrene slabs were created using a bench-top 3D printer. Six slabs were printed at varying densities from 0.23 to 0.68 g/cm3 , corresponding to different density humanoid tissues. The slabs were used to form different single and multilayer geometries. Dose was calculated with EclipseTM AXB 11.0.31 for 6MV, 15MV flattened and 6FFF (flattening filter free) energies for field sizes of 2 * 2 and 5 * 5 cm2 . EBT3 film was inserted into the phantoms, which were irradiated. Absolute dose profiles and 2D Gamma analyses were performed for 96 dose planes. For all single slab configurations and energies, absolute dose differences between the AXB calculation and film measurements remained <3% for both fields in the high-dose region, however, larger disagreement was seen within the penumbra. For the multilayered phantom, percentage depth dose with AXB was within 5% of discrete film measurements. The Gamma index at 2%/2 mm averaged 98% in all combinations of fields, phantoms and photon energies. The transport-based dose algorithm AXB is in good agreement with the experimental measurements for small field sizes using 6MV, 6FFF and 15MV beams adjacent to various low-density heterogeneous media. This work provides preliminary experimental grounds to support the use of AXB for heterogeneous dose calculation purposes.

AB - To investigate the effects of polyphenolic extract from Eucommia ulmoides Oliver leaf (PEEU) on growth performance, digestibility, rumen fermentation and antioxidant status of fattening lambs, 30 weaned male Huzhou lambs were equally divided into three treatments and fed the basal diet supplemented with 0 (CON), 5 (PEEU5) or 10 (PEEU10) g/kg PEEU. Dietary PEEU supplementation did not affect growth performance and apparent digestibility of nutrients. Compared with the CON group, lambs in the PEEU10 group had lower ammonia nitrogen concentration (p < .01) and acetic acid to propionic acid ratio (p < .05) and higher the molar proportion of propionate (p < .05) in rumen fluid. Ammonia nitrogen concentration (p < .01) and the molar proportion of propionate (p < .05) were affected by an interaction between PEEU and sampling day. Dietary PEEU supplementation at 10 g/kg increased total antioxidant capacity (p < .05), superoxide dismutase (p < .05) and glutathione peroxidase (p < .01) activities in serum and glutathione peroxidase activity (p < .05) in liver and decreased (p < .05) malondialdehyde content in serum and liver compared with the CON group. In conclusion, dietary PEEU supplementation affected rumen fermentation patterns and improved antioxidant status of fattening lambs. PMID- 29575597 TI - Anti-HLA alloantibodies of the IgA isotype in re-transplant candidates part II: Correlation with graft survival. AB - We reported previously on the widespread occurrence of anti-HLA alloantibodies of the IgA isotype (anti-HLA IgA) in the sera of solid-organ re-transplantation (re tx) candidates (Arnold et al., ). Specifically focussing on kidney re-tx patients, we now extended our earlier findings by examining the impact of the presence and donor specificity of anti-HLA IgA on graft survival. We observed frequent concurrence of anti-HLA IgA and anti-HLA IgG in 27% of our multicenter collective of 694 kidney re-tx patients. This subgroup displayed significantly reduced graft survival as evidenced by the median time to first dialysis after transplantation (TTD 77 months) compared to patients carrying either anti-HLA IgG or IgA (TTD 102 and 94 months, respectively). In addition, donor specificity of anti-HLA IgA had a significant negative impact on graft survival (TTD 74 months) in our study. Taken together, our data strongly indicate that presence of anti HLA IgA, in particular in conjunction with anti-HLA-IgG, in sera of kidney re-tx patients is associated with negative transplantation outcome.

AB - PURPOSE: To evaluate the relationship between subjective and objective measurements of lens density and the energy of phacoemulsification. SETTING: University Eye Clinic, Maastricht University Medical Centre, Maastricht, the Netherlands. DESIGN: Cross-sectional study. METHODS: The study population included 69 patients. Nuclear opalescence (NO) was graded with the Lens Opacities Classification System III (LOCS III). Thereafter, lens density was measured objectively with Scheimpflug imaging, anterior segment optical coherent tomography and spectral fundus reflectometry (SFR). Cumulative dissipative energy (CDE) and total ultrasound time (US t.t.) of the phacoemulsification were noted. The relationship between the different measurement techniques and energy of phacoemulsification was assessed using Spearman's correlation coefficients. RESULTS: We found moderate to strong correlations between LOCS III and objective measurements of the lens density (rho's from 0.53 to 0.78, p < 0.05) and a moderate correlation between three objective measurement techniques (rho's between 0.29 and 0.57, p < 0.05). There was a moderate correlation between CDE, US t.t. and lens density measurements (rho's from 0.29 to 0.55, p < 0.05), and the highest correlation was found between CDE and NO scores. Exclusion of patients with advanced cortical and posterior subcapsular opacities improved the correlation between SFR and lens density measurements but not the correlation with the energy of phacoemulsification. CONCLUSION: Lens Opacities Classification System III has shown the highest correlation with phacoemulsification energy and may be a preferred technique for prediction of use of phacoemulsification energy. Advanced cortical and posterior opacities may interfere with the quality of objective measurements but do not affect the correlation between lens density measurements and phacoemulsification energy. PMID- 29575600 TI - Genetic counseling globally: Where are we now? AB - The genetic counseling profession is continuing to develop globally, with countries in various stages of development. In some, the profession has been in existence for decades and is increasingly recognized as an important provider of allied health, while in others it is just beginning. In this article, we describe the current global landscape of the genetic counseling specialty field's professional development. Using examples of the United States, United Kingdom, Canada, Australia, South Africa, and various countries in Asia, we highlight the following: (a) status of genetic counseling training programs, (b) availability of credentialing through government and professional bodies (certification, registration, and licensure), and potential for international reciprocity, (c) scope of clinical practice, and (d) health-care system disparities and cultural differences impacting on practice. The successful global implementation of precision medicine will require both an increased awareness of the importance of the profession of "genetic counselor" and flexibility in how genetic counselors are incorporated into each country's health-care market. In turn, this will require more collaboration within and across nations, along with continuing engagement of existing genetic counseling professional societies.

AB - BACKGROUND: Intramedullary nail (IMN) fixation improves functional outcomes for the diaphyseal fractures of long bones. However, locking the distal holes of the IMN is challenging. Although several navigation methods have been proposed, an intuitive, radiation-free and accurate navigation method that does not suffer from problems of hand-eye coordination has not yet been described. METHODS: This paper proposes an augmented reality (AR) surgical navigation method with hybrid optical and electromagnetic (EM) tracking for distal IMN interlocking. Model experiments are designed to evaluate the AR-guided distal interlocking method. RESULTS: AR-guided drilling procedures were performed on 5 tibia models and a leg phantom. The accuracy (hit or miss) was evaluated using fluoroscopy. The experimental results demonstrated that all 18 drills successfully hit the distal holes at a rate of 100%. CONCLUSIONS: Our results indicate that the AR-guided distal interlocking method is feasible and has many potential applications in clinic after further evaluation. PMID- 29575602 TI - Exosomal tetraspanins as regulators of cancer progression and metastasis and novel diagnostic markers. AB - Exosomes are cell-cell communicators emerging as a new paradigm for noninvasive diagnosis and prognosis of treatment response. Exosomal tetraspanin proteins like CD63, CD9 and CD81 play a critical role in sorting, selective recruitment of biomolecules, target selection, cell-specific entry, capturing, angiogenesis and vasculogenesis. These tetraspanins are being used as markers for oral, colorectal and colon cancers and glioblastoma. However, exosomal markers with robust specificity for early detection of carcinomas are the furthest along. EXO CARTA database shows the presence of CD151 in exosomes of colorectal, melanoma, ovarian and prostate cancers. CD151 preferentially targets exosomes to lung, lymph node and stroma cells. The present review discussed the possible role of tetraspanins in the formation, cargo selection, target selection and uptake of exosomes and suggests exciting new directions for future research. PMID- 29575603 TI - The Arabidopsis catalase triple mutant reveals important roles of catalases and peroxisome-derived signaling in plant development. AB - Hydrogen peroxide (H2 O2 ) is generated in many metabolic processes. As a signaling molecule, H2 O2 plays important roles in plant growth and development, as well as environmental stress response. In Arabidopsis, there are three catalase genes, CAT1, CAT2, and CAT3. The encoded catalases are predominately peroxisomal proteins and are critical for scavenging H2 O2 . Since CAT1 and CAT3 are linked on chromosome 1, it has been almost impossible to generate cat1/3 and cat1/2/3 mutants by traditional genetic tools. In this study, we constructed cat1/3 double mutants and cat1/2/3 triple mutants by CRISPR/Cas9 to investigate the role of catalases. The cat1/2/3 triple mutants displayed severe redox disturbance and growth defects under physiological conditions compared with wild type and the cat2/3 double mutants. Transcriptome analysis showed a more profound transcriptional response in the cat1/2/3 triple mutants compared to the cat2/3 mutants. These differentially expressed genes are involved in plant growth regulation as well as abiotic and biotic stress responses. In addition, expression of OXI1 (OXIDATIVE SIGNAL INDUCIBLE 1) and several MAPK cascade genes were changed dramatically in the catalase triple mutant, suggesting that H2 O2 produced in peroxisomes could serve as a peroxisomal retrograde signal. PMID- 29575604 TI - Synthesis of Branched DNA Scaffolded Super-Nanoclusters with Enhanced Antibacterial Performance. AB - Metal nanoclusters (NCs) possess unique optical properties, and exhibit a wide variety of potential applications. DNA with robust molecular programmability is demonstrated as an ideal scaffold to regulate the formation of NCs, offering a rational approach to precisely tune the spatial structures of NCs. Herein, the first use of branched DNA as scaffold to regulate the formation of silver nanoclusters (super-AgNC) is reported, in which the spatial structures are precisely designed and constructed. Super-AgNC with tunable shapes and arm lengths including Y-, X-, and (Y-X)- shaped super-AgNC is achieved. The molecular structures and optical properties of super-AgNCs are systemically studied. As a proof of application, remarkably, super-AgNCs exhibit superior antibacterial performance. In addition, super-AgNCs show excellent biocompatibility with three types of tissue cells including 293T (human embryonic kidney cells), SMCs (vascular smooth muscle cells), and GLC-82 (lung adenocarcinoma cells). These performances enable the super-AgNCs adaptable in a variety of applications such as biosensing, bioimaging, and antibacterial agents. PMID- 29575605 TI - Impact of Cavitation, High Shear Stress and Air/Liquid Interfaces on Protein Aggregation. AB - The reported impact of shear stress on protein aggregation has been contradictory. At high shear rates, the occurrence of cavitation or entrapment of air is reasonable and their effects possibly misattributed to shear stress. Nine different proteins (alpha-lactalbumin, two antibodies, fibroblast growth factor 2, granulocyte colony stimulating factor [GCSF], green fluorescence protein [GFP], hemoglobin, human serum albumin, and lysozyme) are tested for their aggregation behavior on vapor/liquid interfaces generated by cavitation and compared it to the isolated effects of high shear stress and air/liquid interfaces generated by foaming. Cavitation induced the aggregation of GCSF by +68.9%, hemoglobin +4%, and human serum albumin +2.9%, compared to a control, whereas the other proteins do not aggregate. The protein aggregation behaviors of the different proteins at air/liquid interfaces are similar to cavitation, but the effect is more pronounced. Air-liquid interface induced the aggregation of GCSF by +94.5%, hemoglobin +35.5%, and human serum albumin (HSA) +31.1%. The results indicate that the sensitivity of a certain protein toward cavitation is very similar to air/liquid-induced aggregation. Hence, hydroxyl radicals cannot be seen as the driving force for protein aggregation when cavitation occurs. Further, high shear rates of up to 108 s-1 do not affect any of the tested proteins. Therefore, also within this study generated extremely high isolated shear rates cannot be considered to harm structural integrity when processing proteins. PMID- 29575606 TI - Gelatin/nano-hydroxyapatite hydrogel scaffold prepared by sol-gel technology as filler to repair bone defects. AB - This study reports on the development of a scaffold with a gradient of bioactive solid signal embedded in the biodegradable polymer matrix by combining a sol-gel approach and freeze-drying technology. The chemical approach based on the sol-gel transition of calcium phosphates ensures the particles dispersion into the gelatin matrix and a direct control of interaction among COOHgelatin /Ca2+ ions. Morphological analysis demonstrated that on the basis of the amount of inorganic component and by using specific process conditions, it is possible to control the spatial distribution of nanoparticles around the gelatin helix. In fact, methodology and formulations were able to discriminate between the different hydroxyapatite concentrations and their respective morphology. The good biological response represented by good cell attachment, proliferation and increased levels of alkaline phosphatase as an indicator of osteoblastic differentiation of human mesenchymal stem cells toward the osteogenic lineage, demonstrating the effect of bioactive solid signals on cellular behavior. Furthermore, the inhibition of reactive oxygen species production by composite materials predicted potential anti-inflammatory properties of scaffolds thus confirming their biocompatibility. Indeed, these interesting biological results suggest good potential application of this scaffold as filler to repair bone defects. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: Corrected QT interval (QTc) on electrocardiography (ECG) at rest and after exercise in a short daytime recording period may be insufficient for the diagnosis and management of long QT syndrome (LQTS), especially for LQTS type 2 and 3. Therefore, examination of QTc on Holter ECG is important. We designed a method of analyzing QTc on Holter ECG that can be performed in daily clinical practice by combining automatic and manual measurements. METHODS: We reviewed the charts of healthy children (n = 210) and LQTS patients (n = 35) aged <16 years and analyzed QTc at rest and after exercise, and the maximum QTc on Holter ECG. RESULTS: The QTc (Fridericia's correction) of most controls and LQTS patients reached the maximum at night or early in the morning. QTc differed according to sex and age. In the control group, QTc on ECG of all three types tended to lengthen with age. QTc after exercise was slightly longer than QTc at rest, and the maximum QTc on Holter ECG was much longer than both, reaching >450 ms in boys and 500 ms in girls. In most LQTS type 1 patients, QTc after exercise and that on Holter ECG tended to be long. In most LQTS type 2 and 3 patients, QTc at rest and that after exercise was long, and that on Holter ECG tended to be much longer. CONCLUSIONS: The present method of analyzing QTc on Holter ECG, in which automatic and manual measurements are combined, is practical and may be useful for diagnosis and risk stratification of LQTS. PMID- 29575608 TI - The association between reading abilities and visual-spatial attention in Hong Kong Chinese children. AB - A growing body of research suggests that visual-spatial attention is important for reading achievement. However, few studies have been conducted in non alphabetic orthographies. This study extended the current research to reading development in Chinese, a logographic writing system known for its visual complexity. Eighty Hong Kong Chinese children were selected and divided into poor reader and typical reader groups, based on their performance on the measures of reading fluency, Chinese character reading, and reading comprehension. The poor and typical readers were matched on age and nonverbal intelligence. A Posner's spatial cueing task was adopted to measure the exogenous and endogenous orienting of visual-spatial attention. Although the typical readers showed the cueing effect in the central cue condition (i.e., responses to targets following valid cues were faster than those to targets following invalid cues), the poor readers did not respond differently in valid and invalid conditions, suggesting an impairment of the endogenous orienting of attention. The two groups, however, showed a similar cueing effect in the peripheral cue condition, indicating intact exogenous orienting in the poor readers. These findings generally supported a link between the orienting of covert attention and Chinese reading, providing evidence for the attentional-deficit theory of dyslexia. PMID- 29575610 TI - A red cell preservation strategy reduces postoperative transfusions in pediatric heart surgery patients. AB - BACKGROUND: Blood transfusion has well-documented adverse effects. As part of a blood conservation initiative at our center, we began routine use of cell saver for all congenital heart surgery performed on cardiopulmonary bypass since 2014. AIMS: This study aimed to compare transfusion rates prior to, and in the first and second year after this initiative. We hypothesized that cell saver use would decrease transfusion requirements in second year after use of the cell saver compared to the pre cell saver group. METHODS: Consecutive patients under 18 years undergoing congenital heart surgery on cardiopulmonary bypass were retrospectively analyzed as 3 one-year cohorts defined above. We excluded patients who required mechanical support or reoperation at index admission. Baseline characteristics, and use of blood intraoperatively and postoperatively were compared between groups. RESULTS: The 3 groups had similar baseline characteristics. Blood use was significantly lower in year 2 after cell saver initiation as compared to the pre cell saver group both intra- and postoperatively. The median difference in volume of intraoperative blood transfusion was lower by 138 mL/m2 (-266, -10 mL/m2 ) in year 2 when compared to the pre cell saver group. Similarly, the proportion of subjects requiring red blood cell transfusion postoperatively on day of surgery was lower by 10% (-15%, 6%). CONCLUSION: Standardized use of cell saver significantly decreased perioperative blood use in children undergoing cardiac surgery at our center. A risk-adjusted transfusion threshold for children undergoing heart surgery needs to be developed to further decrease exposure to blood products and associated costs. PMID- 29575609 TI - Long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 promotes lung adenocarcinoma by directly interacting with specificity protein 1. AB - Metastasis-associated lung adenocarcinoma transcript 1 (malat1) is an oncogenic long non-coding RNA (lncRNA) which has been proven to be associated with various types of tumors. Transcription factor specificity protein 1 (SP1) is overexpressed in many types of cancers. Previously, we observed that malat1 expression level is regulated by SP1 in lung cancer. In the present study, we found that transfection of expression construct of malat1 5' end fragment M5 enhances stability and transcriptional activity of SP1. Various SP1 target genes are also upregulated following overexpression of malat1 M5 in lung adenocarcinoma cells. We also showed that malat1 M5 interacts with the C-terminal domain of SP1 by RNA immunoprecipitation (RIP) assay coupled with UV cross-linking. Malat1-SP1 association results in increase of SP1 stability. In turn, SP1 promotes malat1 transcription, thus forming a positive feedback loop. In conclusion, our data show that in lung adenocarcinoma cells, malat1 interacts with SP1 protein and promotes SP1-mediated transcriptional regulation of SP1 target genes. PMID- 29575611 TI - A Mathematical Model for Predicting Obesity Transmission with Both Genetic and Nongenetic Heredity. AB - OBJECTIVE: Obesity is transmissible across generations through both genetic and nongenetic routes, but distinguishing between these factors is challenging. This study aimed to quantitatively examine the contribution of these genetic and nongenetic effects to assess their influence on obesity prevalence. METHODS: A mathematical model was proposed that incorporated both the genetic and nongenetic effects of obesity. Model parameters were estimated by using observational data. Model simulations were used to assess the sensitivity of model parameters. To strengthen the study's approach, parameter estimation and simulation using data from the United Kingdom were also performed. RESULTS: Individuals homozygous for a "hypothetical obesogenic gene" were suggested to be more susceptible to both socially contagious risk and spontaneous weight gain risk. The model predicted that obesity prevalence would reach 41.03% (39.28, 44.31) and 26.77% (25.62, 28.06) at 2030 in the United States and United Kingdom, respectively. The socially contagious risk factor had a greater overall impact on the distribution of the population with obesity than did spontaneous weight gain risk or mother-to child obesity transmission risk. CONCLUSIONS: Although the proposed "first approximation" model captured the complex interactions between the genetic and nongenetic effects on obesity, this framework remains incomplete. Future work should incorporate other key features driving the obesity epidemic. PMID- 29575612 TI - Assessment of the metabolism and morphology of the porcine cornea, lens and retina by 2-photon imaging. AB - Two-photon imaging is a noninvasive imaging technique with increasing importance in the biological and medical fields since it allows intratissue cell imaging with high resolution. We demonstrate the feasibility of using a single 2-photon instrument to evaluate the cornea, the crystalline lens and the retina based on their autofluorescence (AF). Image acquisition was performed using a custom-built 2-photon microscope for 5-dimensional microscopy with a near infrared broadband sub-15 femtosecond laser centered at 800 nanometers. Signals were detected using a spectral photomultiplier tube. The spectral ranges for the analysis of each tissue/layer AF were determined based on the spectra of each tissue as well as of pure endogenous fluorophores. The cornea, lens and retina are characterized at multiple depths with subcellular resolution based on their morphology and AF lifetime. Additionally, the AF lifetime of NAD(P)H was used to assess the metabolic activity of the cornea epithelium, endothelium and keratocytes. The feasibility to evaluate the metabolic activity of lens epithelial cells was also demonstrated, which may be used to further investigate the pathogenesis of cataracts. The results illustrate the potential of multimodal multiphoton imaging as a novel ophthalmologic technique as well as its potential as a diagnostic tool. PMID- 29575613 TI - Humanization of fibroblast growth factor 1 single-chain antibody and validation for its antitumorigenic efficacy in breast cancer and glioma cells. AB - Single-chain variable fragment (scFv) antibodies are the smallest immunoglobulins with high antigen-binding affinity. We have previously reported that fibroblast growth factor 1 played pivotal roles in cancer development and generated a mouse scFv (mscFv1C9) could effectively prohibit cancer cell proliferation in vitro and in vivo. Here, we further humanized this scFv (hscFv1C9) using a structure-guided complementarity determining region grafting strategy. The purified hscFv1C9 maintained similar antigen-binding affinity and specificity as mscFv1C9, and it was capable of inhibiting growth of different tumours in vitro and in vivo. These data strongly suggested that hscFv1C9 has antitumour potentials. PMID- 29575614 TI - Combination of RIZ1 Overexpression and Radiotherapy Contributes to Apoptosis and DNA Damage of HeLa and SiHa Cervical Cancer Cells. AB - Although radiotherapy has been widely applied to treating cervical cancer in the clinic, its therapeutic efficacy is often restricted to the radioresistance of cancer cells. Retinoblastoma protein-interacting zinc finger gene 1 (RIZ1) has been suggested as a tumour suppressor gene, whereas its role in cervical cancer with or without radiotherapy has been unclear. In this study, two cervical cancer cell lines, HeLa and SiHa cells, stably transfected with RIZ1 overexpression plasmid were subjected to ionizing radiation, and their survival fractions were calculated by assessing their clonogenic abilities. Our results showed that the forced overexpression of RIZ1 significantly reduced the clonogenic survival rates of both HeLa and SiHa cells exposed to ionizing radiation. By analysing the cell apoptotic status, we found that the RIZ1-overexpressed cervical cancer cells under ionizing radiation were more vulnerable to damage, and more gamma-H2AX foci were found in these cells. Furthermore, the volumes of tumour xenografts formed by the RIZ1-overexpressed cells in nude mice under ionizing radiation were smaller than those generated by the control cells. There were more morphological changes, apoptosis cells and lower expression of PCNA in RIZ1-overexpressed tumour tissues of mice after exposure to ionizing radiation. Taken together, our study demonstrates that the overexpression of RIZ1 combined with radiotherapy facilitates apoptosis and DNA damage of cervical cancer cells. PMID- 29575615 TI - Spectrum of hemostatic disorders in Indian females presenting with bleeding manifestations. AB - INTRODUCTION: Hemostatic disorders are often missed in women with bleeding particularly menorrhagia. Preexisting hemostatic disorders are now known as common risk factor for postpartum hemorrhage and prolonged bleeding in puerperium. Females with bleeding complaints constitute an important population referred to hematology clinic. Hence, we aim to evaluate the type and frequency of hemostatic disorders among females presenting with bleeding in a tertiary care hospital and a basic hemostatic laboratory. METHODS: Three-year data were retrospectively analyzed for 200 females with various bleeding complaints. Due to resource constraints, a hemostatic workup was done with prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen assay, clot solubility test, mixing studies, specific factor assays, platelet function test, and von Willebrand factor antigen level. RESULTS: A total of 200 females were investigated to identify the cause of their bleeding. Thirty-five of 200 (17.5%) females were found with an underlying bleeding disorder. Of these 35 females, 65.7% presented with bleeding from more than 1 site. Most common bleeding manifestation was spontaneous bruising in 18 of 35 (51.4%) patients followed by petechiae (48.6%). Inherited bleeding disorders were noted in majority. The most common inherited bleeding disorder identified was von Willebrand disease (VWD) in 34.3% females. Second most common disorder was Glanzmann's thrombasthenia accounting for 22.8%. Rare coagulation factor deficiency, such as factors VII, X, and XIII deficiencies, was noted. Three cases revealed acquired causes of coagulation defects. CONCLUSION: Underlying hemostatic defects should be searched for in women with unexplained bleeding complaints. This will not only help in diagnosis but also in proper management for future hemostatic challenges. PMID- 29575616 TI - Autosomal dominant Robinow syndrome associated with a novel DVL3 splice mutation. AB - Robinow syndrome is a clinically and genetically heterogeneous disorder characterized by mesomelic limb shortening, distinctive facial features, and variable oral, cardiac, vertebral, and urogenital malformations. We identified the novel de novo splice acceptor mutation c.1715-2A > C in DVL3 in a 15-year-old female patient with typical features of Robinow syndrome. By studying DVL3 transcripts in this patient, we confirmed expression of both wild-type and mutant alleles. Mutant DVL3 mRNAs were found to harbor a deletion of four nucleotides at the beginning of exon 15 and encode a protein product with a distinct -1 reading frame C-terminus. The data demonstrate that mutant DVL3 proteins associated with Robinow syndrome show truncation of the C-terminus and share 83 novel amino acid residues before the stop codon confirming highly specific DVL3 alterations to be associated with this syndrome. The phenotype of the Robinow syndrome-affected female reported here is typical as she shows mesomelia and mild hand anomalies as well as characteristic facial anomalies. She also exhibited a supraumbilical midline abdominal raphe which has not been observed in other patients with Robinow syndrome. In contrast to the clinical data of four previously reported individuals with DVL3-related Robinow syndrome, short stature was not present in this individual at the age of 15 years. These findings expand the clinical spectrum of Robinow syndrome associated with DVL3 mutations. To date, comparison of clinical data of DVL3 mutation-positive individuals with those of patients with genetically different forms did not allow delineation of gene-specific phenotypes. PMID- 29575617 TI - Novel RSPO1 mutation causing 46,XX testicular disorder of sex development with palmoplantar keratoderma: A review of literature and expansion of clinical phenotype. AB - Palmoplantar hyperkeratosis with squamous cell carcinoma of skin and sex reversal (MIM # 610644) is a clinically distinctive form of SRY-negative 46,XX disorder of sex development. It is a rare autosomal recessive disorder caused due to biallelic loss of function mutations in RSPO1 gene. RSPO1 acts by activating the canonical beta-catenin pathway and is one of the most important genes controlling female gonadal differentiation. RSPO1-associated disorders of sex development have been described only in three instances in the past. We report fourth such case with additional findings and perform a comparative review of previous phenotypic descriptions, thereby expanding the clinical phenotype of this syndrome. PMID- 29575618 TI - A homozygous TTN gene variant associated with lethal congenital contracture syndrome. AB - Pathogenic variants in the TTN gene have been reported to cause various cardiomyopathies and a range of skeletal muscle diseases, collectively known as titinopathies. We evaluated a consanguineous family multiple members affected with a lethal congenital contracture syndrome. Using exome sequencing, we identified a homozygous c.36122delC (p. P12041Lfs*20) variant in exon 167 in the fetal IC isoform of TTN. The finding expands the phenotypes that can be caused by pathogenic variants TTN, which should be considered in lethal congenital contracture syndromes, arthrogryposis multiplex congenita, congenital myopathies, and hydrops fetalis.

PMID- 29575623 TI - Low serum fatty acid levels in pregnancies with fetal gastroschisis: A prospective study. AB - Fetal gastroschisis is a paraumbilical abdominal wall defect with herniation of abdominal organs. The underlying cause of the disease remains unknown; however, studies suggest that nutritional factors may play a role in its development. This prospective case-control study explored the association of serum fatty acid levels of pregnant women and occurrence of gastroschisis. Gastroschisis group comprised 57 pregnant women with fetuses with gastroschisis, and the control group comprised 114 pregnant women with normal fetuses. Serum fatty acids levels were compared between the groups for the overall pregnancy at <34 weeks; <=25 weeks, and >25 and <34 weeks; and at delivery. Total fatty acids (p = .008), unsaturated fatty acids (p = .002), and the C18:1n9/C18:00 ratio (p = .021) were lower in the gastroschisis group than in the control group during the overall pregnancy; however, the C16:00/C18:2n6 ratio (p = .018) was higher in the gastroschisis group than in the control group during the same period. Total fatty acids (p = .044) and unsaturated fatty acids (p = .024) were lower in the gastroschisis group at <=25 weeks, and unsaturated fatty acid (p = .025) and the C18:1n9/C18:00 ratio (p = .013) were lower in the gastroschisis group than in the control group at >25 and <34 weeks. Pregnant women with fetuses with gastroschisis have low serum fatty acids levels during pregnancy. These findings suggest that fatty acids levels may be involved in the pathogenesis of fetal gastroschisis. PMID- 29575622 TI - Elucidating the diagnostic odyssey of 22q11.2 deletion syndrome. AB - Clinical molecular testing has been available for 22q11.2 deletion syndrome (22q11.2DS) for over two decades yet under-recognition and diagnostic delays are common. To characterize the "diagnostic odyssey" in 22q11.2DS we studied 202 well characterized unrelated adults, none ascertained through an affected relative. We used a regression model to identify clinical and demographic factors associated with length of time to molecular diagnosis. Kaplan-Meier analysis compared time to diagnosis for the molecular testing era (since 1994) and earlier birth cohorts. The results showed that the median time to molecular diagnosis of the 22q11.2 deletion was 4.7 (range 0-20.7) years. Palatal and cardiac anomalies, but not developmental delay/intellectual disability, were associated with a shorter time to molecular diagnosis. Non-European ethnicity was associated with longer time to diagnosis. Inclusion of a cohort from another 22q11.2DS center increased power to observe a significantly earlier diagnosis for patients born in the molecular testing era. Nonetheless, only a minority were diagnosed in the first year of life. On average, patients were seen in seven (range 2-15) different clinical specialty areas prior to molecular diagnosis. The findings indicate that even for those born in the molecular testing era, individuals with 22q11.2DS and their families face a diagnostic odyssey that is often prolonged, particularly in the absence of typical physical congenital features or for those of non-European ancestry. The results support educational efforts to improve clinical recognition and testing, and ultimately newborn screening as a means of maximizing early detection that would provide the best opportunity to optimize outcomes. PMID- 29575624 TI - First-year growth in children with Noonan syndrome: Associated with feeding problems? AB - Children with Noonan syndrome show rapid decline of growth in the first year of life and feeding problems are present in over 50%. The aim of this study was to explore whether growth decelerates because of feeding problems or other Noonan syndrome-related factors. We performed a retrospective, longitudinal cohort study of clinically and genetically diagnosed subjects with Noonan syndrome (n = 143). Questionnaires about the phenotypic-genotypic profile and reported feeding problems were sent to eligible subjects. Data on first-year growth was obtained from growth charts. Ninety-one participants were excluded because of different criteria. A total of 52 subjects with Noonan syndrome were included. The largest decline in weight and length standard deviation score (SDS) occurred in the first 2.5 months after birth (-1.93 and -1.15, respectively), with feeding problems causing a decline of 0.57 SDS in the remaining months. At 1 year, children with feeding problems were on average 290 g lighter and 0.8 cm shorter than children without feeding problems. Weight gain was also negatively influenced by having a PTPN11 mutation (n = 39) and a higher gestational age, whereas children of parents with Noonan syndrome and with a higher birth weight gained more weight. Growth in length was reduced by having cardiac surgery and a higher gestational age, but positively influenced by birth length and maternal height. Growth in children with Noonan syndrome is impaired right after birth and only partially associated with feeding problems. In addition, several specific Noonan syndrome related factors seem to influence growth in the first year. PMID- 29575626 TI - Challenges associated with parenting youth with neurofibromatosis: A qualitative investigation. AB - Parents of children with the neurofibromatoses (NF; neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis) are at an increased risk for emotional and physical health problems. This study aimed to determine parents' perceptions of stressors associated with parenting a child with NF in order to inform the development of a resiliency intervention. We conducted three live video semi structured focus groups with parents of youth with NF (N = 30), which were subsequently transcribed and coded using qualitative content analysis. Parents reported heightened stress associated with the child's educational, medical, and social needs, as well as concerns about their child's physical and mental health. They also reported stress associated with managing finances, multiple medical appointments, role challenges (i.e., being a parent or partner), and managing the uncertainty/unpredictability of their child's NF diagnosis. These stressors reportedly affected employment status (i.e., work scale backs), relationships (i.e., social, familial, with partner, other children), and the parents' physical and mental health. All participants expressed interest in a mind body program aimed at improving resiliency by teaching coping skills (e.g., mindfulness, adaptive thinking, positive psychology skills) and enhancing social support. Results show parents' enthusiasm for a resiliency intervention targeting stress associated with parenting a child with NF, and provide valuable information for the content of the intervention and its delivery modality. PMID- 29575627 TI - A recurrent mutation causing Melnick-Needles syndrome in females confers a severe, lethal phenotype in males. AB - Melnick-Needles syndrome (MNS; MIM 309350) is an X-linked skeletal dysplasia caused by mutations in FLNA. Females with the condition present with characteristic facial features, short stature, skeletal anomalies, including poorly modeled and sclerotic bones, and structural abnormalities such as cardiac and urological defects. Previously males were thought to present with either a mild phenotype compatible with life or a severe lethal presentation depending on the maternal phenotype. The discovery of a limited number of mutations in FLNA as the cause of the condition has clarified the molecular basis of the disorder, but only a very small number of severely affected males have been reported with MNS. Furthermore, no mildly affected males have been described with a molecular confirmation of the condition. In this report, we describe the clinical and molecular findings of a mildly affected mother with MNS and her severely affected son. They shared a well-documented disease-causing variant in FLNA, p.(Ala1188Thr), one of two highly recurrent mutations leading to the disorder. This is only the fourth report of a male with perinatal lethal MNS and a molecular confirmation; it is the first description of this specific mutation in a male. PMID- 29575628 TI - Congenital sodium diarrhea and chorioretinal coloboma with optic disc coloboma in a patient with biallelic SPINT2 mutations, including p.(Tyr163Cys). AB - Congenital sodium diarrhea is a rare and life-threatening disorder characterized by a severe, secretory diarrhea containing high concentrations of sodium, leading to hyponatremia and metabolic acidosis. It may occur in isolation or in association with systemic features such as facial dysmorphism, choanal atresia, imperforate anus, and corneal erosions. Mutations in the serine protease inhibitor, Kunitz-Type 2 (SPINT2) gene have been associated with congenital sodium diarrhea and additional syndromic features. We present a child with congenital sodium diarrhea, cleft lip and palate, corneal erosions, optic nerve coloboma, and intermittent exotropia who was found to have biallelic mutations in SPINT2. One mutation, c.488A > G, predicting p.(Tyr163Cys), has been previously associated with a syndromic form of congenital sodium diarrhea. The other mutation, c.166_167dupTA, predicting p.(Asn57Thrfs*24) has not previously been reported and is likely a novel pathogenic variant for this disorder. We found only one other report of an optic nerve coloboma associated with SPINT2 mutations and this occurred in a patient with congenital tufting enteropathy. Our patient confirms an association of ocular coloboma with presumed loss of SPINT2 function. PMID- 29575629 TI - Three novel GJB2 (connexin 26) variants associated with autosomal dominant syndromic and nonsyndromic hearing loss. AB - Connexin 26 (Cx26), encoded by the GJB2 gene, is a key protein involved in the formation of gap junctions in epithelial organs including the inner ear and palmoplantar epidermis. Pathogenic variants in GJB2 are responsible for approximately 50% of inherited sensorineural deafness. The majority of these variants are associated with autosomal recessive inheritance; however, rare reports of dominantly co-segregating variants have been published. Since we began offering GJB2 testing in 2003, only about 2% of detected GJB2 variants from our laboratory have been classified as dominant. Here we report three novel dominant GJB2 variants (p.Thr55Ala, p.Gln57_Pro58delinsHisSer, and p.Trp44Gly); two associated with syndromic sensorineural hearing loss and one with nonsyndromic hearing loss. In the kindred with the p.Thr55Ala variant, the proband and his father present with only leukonychia as a cutaneous finding of their syndromic hearing loss. This phenotype has been previously documented in conjunction with palmoplantar hyperkeratosis, but isolated leukonychia is a novel finding likely associated with the unique threonine to alanine change at codon 55 (other variants at this codon have been reported in cases of nonsyndromic hearing loss). This report contributes to the short list of GJB2 variants associated with autosomal dominant hearing loss, highlights the variability of skin and nail findings associated with such cases, and illustrates the occurrence of both syndromic and nonsyndromic presentations with changes in the same gene. PMID- 29575630 TI - Isosorbide dinitrate in nephronophthisis treatment. AB - Nephronophthisis is a progressive disease that affects development of the renal tubules and leads to end stage renal disease. Many affected children have isolated renal disease; however, there can be additional manifestations including heart defects, liver fibrosis, brain malformations, and situs inversus. There is no way to slow or modify the disease. We describe a patient who presented at birth with cholestatic jaundice and decreased kidney function, found by exome sequencing to have two NPHP3 variants. Her clinical status deteriorated rapidly, and two disease-modifying agents were given in hopes of slowing disease progression, the arginine vasopressin type II receptor antagonist tolvaptan to stabilize her renal function and isosorbide dinitrate to manage her poorly controlled hypertension. Tolvaptan therapy initiated at 82 days of life had limited effect on the rate of decline in renal function and was insufficient to abrogate the need for dialysis; however, isosorbide dinitrate therapy led to a dramatic improvement in blood pressure control and allowed for the discontinuation of multiple anti-hypertensive agents. This is the first report of the use of tolvaptan and isosorbide dinitrate for nephronophthisis management. We suggest that isosorbide dinitrate may represent a disease-modifying agent in nephronophthisis treatment. PMID- 29575631 TI - Biallelic loss-of-function WNT5A mutations in an infant with severe and atypical manifestations of Robinow syndrome. AB - Robinow syndrome (RS) is a well-recognized Mendelian disorder known to demonstrate both autosomal dominant and autosomal recessive inheritance. Typical manifestations include short stature, characteristic facies, and skeletal anomalies. Recessive inheritance has been associated with mutations in ROR2 while dominant inheritance has been observed for mutations in WNT5A, DVL1, and DVL3. Through trio whole genome sequencing, we identified a homozygous frameshifting single nucleotide deletion in WNT5A in a previously reported, deceased infant with a unique constellation of features comprising a 46,XY disorder of sex development with multiple congenital malformations including congenital diaphragmatic hernia, ambiguous genitalia, dysmorphic facies, shortened long bones, adactyly, and ventricular septal defect. The parents, who are both heterozygous for the deletion, appear clinically unaffected. In conjunction with published observations of Wnt5a double knockout mice, we provide evidence for the possibility of autosomal recessive inheritance in association with WNT5A loss-of function mutations in RS.

AB - We describe a neonatal patient with fixed dilated pupils and pulmonary, bladder, and bowel dysfunction suspicious for the presence of ACTA2 R179 mediated multisystemic smooth muscle dysfunction syndrome. Whole exome sequencing revealed compound heterozygous mutations in MYH11 after ACTA2 specific testing revealed no abnormalities. The child lived until 18 months of age and represents the only reported case of an MYH11 compound heterozygote with widespread smooth muscle dysfunction.

PMID- 29575634 TI - Impact of intravenous thrombolysis and emergent carotid stenting on reperfusion and clinical outcomes in patients with acute stroke with tandem lesion treated with thrombectomy: a collaborative pooled analysis. AB - BACKGROUND AND PURPOSE: Tandem anterior circulation lesions in the setting of acute ischemic stroke (AIS) are a complex endovascular situation that has not been specifically addressed in trials. We determined the predictors of successful reperfusion and good clinical outcome at 90 days after mechanical thrombectomy (MT) in patients with AIS with tandem lesions in a pooled collaborative study. METHODS: This was a retrospective analysis of consecutive patients presenting to 18 comprehensive stroke centers with AIS due to tandem lesion of the anterior circulation who underwent MT. RESULTS: A total of 395 patients were included. Successful reperfusion (modified thrombolysis in cerebral infarction score 2b-3) was achieved in 76.7%. At 90 days, 52.2% achieved a good outcome (modified Rankin Scale score 0-2), 13.8% suffered a parenchymal hematoma and 13.2% were dead. Lower National Institutes of Health Stroke Scale score [odds ratio (OR), 1.26; 95% confidence intervals (CI), 1.07-1.48, P = 0.004], Alberta Stroke Program Early CT Score >=7 (OR, 2.00; 95% CI, 1.07-3.43, P = 0.011), intravenous thrombolysis (OR, 1.47; 95% CI, 1.01-2.12, P = 0.042) and stenting of the extracranial carotid lesion (OR, 1.63; 95% CI, 1.04-2;53, P = 0.030) were independently associated with successful reperfusion. Lower age (OR, 1.58; 95% CI, 1.26-1.97, P < 0.001), absence of hypercholesterolemia (OR, 1.77; 95% CI, 1.10-2.84, P = 0.018), lower National Institutes of Health Stroke Scale scores (OR, 2.04; 95% CI, 1.53-2.72, P < 0.001), Alberta Stroke Program Early CT Score >=7 (OR, 2.75; 95% CI, 1.24-6.10, P = 0.013) and proximal middle cerebral artery occlusion (OR, 1.59; 95% CI, 1.03-2.44, P = 0.035) independently predicted a good 90-day outcome. CONCLUSIONS: Intravenous thrombolysis and emergent stenting of the extracranial carotid lesion were predictors of a successful reperfusion after MT of patients with AIS with tandem lesion of the anterior circulation. PMID- 29575636 TI - Interactions of Fullerene-Polyglycerol Sulfates at Viral and Cellular Interfaces. AB - Understanding the mechanism of interactions of nanomaterials at biointerfaces is a crucial issue to develop new antimicrobial vectors. In this work, a series of water-soluble fullerene-polyglycerol sulfates (FPS) with different fullerene/polymer weight ratios and varying numbers of polyglycerol sulfate branches are synthesized, characterized, and their interactions with two distinct surfaces displaying proteins involved in target cell recognition are investigated. The combination of polyanionic branches with a solvent exposed variable hydrophobic core in FPS proves to be superior to analogs possessing only one of these features in preventing interaction of vesicular stomatitis virus coat glycoprotein (VSV-G) with baby hamster kidney cells serving as a model of host cell. Interference with L-selectin-ligand binding is dominated by the negative charge, which is studied by two assays: a competitive surface plasmon resonance (SPR)-based inhibition assay and the leukocyte cell (NALM-6) rolling on ligands under flow conditions. Due to possible intrinsic hydrophobic and electrostatic effects of synthesized compounds, pico- to nanomolar half maximal inhibitory concentrations (IC50 ) are achieved. With their highly antiviral and anti-inflammatory properties, together with good biocompatibility, FPS are promising candidates for the future development towards biomedical applications. PMID- 29575637 TI - Effect of rosuvastatin on risk markers for venous thromboembolism in cancer. AB - : Essentials Statins lower venous thromboembolism risk in general but have not been studied in cancer patients. We completed a randomized trial of rosuvastatin vs. placebo among cancer patients on chemotherapy. Rosuvastatin did not significantly lower prothrombotic biomarkers including D-dimer. The role of statins in venous thrombosis prevention in cancer patients remains unknown. SUMMARY: Background Statin therapy is associated with lower risk of venous thromboembolism (VTE) but has not been prospectively evaluated in patients with advanced cancer. Objectives We determined if statin administration in this high risk population reduces the risk of VTE, based on established and emerging biomarkers. Patients/Methods This double-blind, crossover, randomized controlled trial among patients with advanced cancer receiving systemic therapy allocated participants to rosuvastatin 20 mg daily or placebo for 3-4 weeks prior to crossover to the alternative therapy, with a 3-5-week washout. D-dimer, C reactive protein (CRP), soluble (s)P-selectin, factor VIII (FVIII), thrombin generation and exploratory biomarkers focusing on endogenous thrombin potential, including tissue factor (TF), activated factor IX (FIXa) and activated factor XI (FXIa), were measured at the start and end of both treatment periods. The primary outcome was change in D-dimer with rosuvastatin compared with placebo. Results Of 38 enrolled participants, 24 (63%) completed the study. Rosuvastatin did not cause statistically significant changes in D-dimer levels or any other biomarker. CRP levels decreased by 40%; 4.3 mg L-1 (95% confidence interval, -11.0 to +2.5 mg L-1 ) compared with placebo. In post-hoc analysis, participants who received rosuvastatin initially during their first line of treatment had a 13% decrease in D-dimer. Circulating TF, FIXa and FXIa were detected in 26%, 68% and 71% of cancer patients despite not being found in healthy individuals. Conclusions Rosuvastatin did not cause favorable changes in biomarkers of VTE risk in advanced cancer patients receiving chemotherapy. The role of statin therapy as thromboprophylaxis in the cancer population remains uncertain. PMID- 29575635 TI - Biomarkers as Common Data Elements for Symptom and Self-Management Science. AB - PURPOSE: Biomarkers as common data elements (CDEs) are important for the characterization of biobehavioral symptoms given that once a biologic moderator or mediator is identified, biologically based strategies can be investigated for treatment efforts. Just as a symptom inventory reflects a symptom experience, a biomarker is an indicator of the symptom, though not the symptom per se. The purposes of this position paper are to (a) identify a "minimum set" of biomarkers for consideration as CDEs in symptom and self-management science, specifically biochemical biomarkers; (b) evaluate the benefits and limitations of such a limited array of biomarkers with implications for symptom science; (c) propose a strategy for the collection of the endorsed minimum set of biologic samples to be employed as CDEs for symptom science; and (d) conceptualize this minimum set of biomarkers consistent with National Institute of Nursing Research (NINR) symptoms of fatigue, depression, cognition, pain, and sleep disturbance. DESIGN AND METHODS: From May 2016 through January 2017, a working group consisting of a subset of the Directors of the NINR Centers of Excellence funded by P20 or P30 mechanisms and NINR staff met bimonthly via telephone to develop this position paper suggesting the addition of biomarkers as CDEs. The full group of Directors reviewed drafts, provided critiques and suggestions, recommended the minimum set of biomarkers, and approved the completed document. Best practices for selecting, identifying, and using biological CDEs as well as challenges to the use of biological CDEs for symptom and self-management science are described. Current platforms for sample outcome sharing are presented. Finally, biological CDEs for symptom and self-management science are proposed along with implications for future research and use of CDEs in these areas. FINDINGS: The recommended minimum set of biomarker CDEs include pro- and anti-inflammatory cytokines, a hypothalamic-pituitary-adrenal axis marker, cortisol, the neuropeptide brain derived neurotrophic factor, and DNA polymorphisms. CONCLUSIONS: It is anticipated that this minimum set of biomarker CDEs will be refined as knowledge regarding biologic mechanisms underlying symptom and self-management science further develop. The incorporation of biological CDEs may provide insights into mechanisms of symptoms, effectiveness of proposed interventions, and applicability of chosen theoretical frameworks. Similarly, as for the previously suggested NINR CDEs for behavioral symptoms and self-management of chronic conditions, biological CDEs offer the potential for collaborative efforts that will strengthen symptom and self-management science. CLINICAL RELEVANCE: The use of biomarker CDEs in biobehavioral symptoms research will facilitate the reproducibility and generalizability of research findings and benefit symptom and self-management science. PMID- 29575638 TI - Improving bone marrow biopsy quality through peer discussion and data comparisons: A single institution experience. AB - INTRODUCTION: Bone marrow biopsy (BMB) is crucial for the diagnosis, staging, and monitoring of a variety of hematologic diseases. Obtaining an adequate BMB can be challenging given the need to balance patient comfort with acquisition of high quality specimens. We had observed variable BMB quality at our institution with poor quality specimens sometimes affecting diagnosis. We thus undertook this quality improvement (QI) project to improve the quality of diagnostic BMB specimens. METHODS: We used an A3 QI process to identify factors possibly influencing BMB quality. We collected baseline data on 211 BMB, with short and long-term follow-up data on a further 382 cases. We used clinical conferences to discuss data, perform peer comparisons and identify strategies to create a sustainable improvement in BMB quality. RESULTS: Baseline data showed that BMB length was influenced most by the individual performer, with some influence of needle gauge. Other factors such as sedation, BMB indication were noncontributory. BMB lengths improved following performer education and individual performer data comparisons (15.2 mm post vs 12.8 mm baseline, P < .0001) and with use of an 8- rather than 11-gauge needle (18.3 mm 8-gauge vs 13.3 mm 11-gauge P < .0001), and were sustained over the long term. CONCLUSIONS: Education on BMB standards, sharing of performer data, and changing needle gauge are relatively straightforward methods to improve BMB quality, leading to easier pathology diagnosis. PMID- 29575639 TI - Recurrent inhibition is higher in eccentric compared to isometric and concentric maximal voluntary contractions. AB - AIM: This study was designed to investigate the influence of muscle contraction type on spinal recurrent inhibition during maximal voluntary contractions (MVC) of the plantar flexor muscles. METHODS: To that purpose, the paired Hoffmann reflex (H-reflex) technique permitted to assess changes in recurrent pathway by comparing the modulations of test, reference and conditioning H-reflexes (H', Href and H1 respectively) in the soleus muscle during isometric, concentric and eccentric MVC. Twenty-five subjects participated in an experimental session designed to assess the activity of the recurrent inhibition pathway. RESULTS: The results indicate that both the electromyographic activity and the amplitude of H1 normalized to the maximal M-wave (Mmax ) were similar regardless of the muscle contraction type while the ratio between H' and H1 amplitudes was significantly smaller during eccentric compared with isometric and concentric MVC. Furthermore, Href and H' amplitudes did not differ significantly during both isometric and concentric MVCs while H' amplitude was significantly lower than Href amplitude during eccentric MVC. In addition, the V/Mmax ratio was similar for all muscle contraction type and greater H' amplitude was significantly correlated with greater V-wave amplitude regardless of the muscle contraction type. CONCLUSION: Together, the current results indicate that recurrent inhibition is elevated for the soleus muscle during eccentric compared to isometric and concentric MVC. Data further suggest that the Renshaw cell activity is specifically controlled by the descending neural drive and/or peripheral neural mechanisms during eccentric MVC. PMID- 29575640 TI - Potentially traumatic events in youth with and at clinical high risk for psychosis. AB - AIM: Previous research has demonstrated a strong association between early trauma exposure and the development of psychotic symptoms. However, few of these studies have included young adolescents and children. This study investigated rates and number of potentially traumatic experiences (PTEs) among typically developing youth (TD; n = 21), youth at clinical high risk for psychosis (CHR; n = 38), and youth with a psychotic disorder (PD; n = 28) between 7 and 18 years of age. CHR participants were further evaluated to determine whether a history of PTEs was associated with prodromal symptom severity. METHODS: Study group inclusion was determined by structured interviews. Trauma history was assessed using the post traumatic stress disorder module of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. CHR participants with vs without a history of PTEs were compared on severity of prodromal symptoms. RESULTS: CHR and PD participants reported significantly higher rates and numbers of PTEs than TD participants. Contrary to expectations and prior research, CHR participants with vs without a history of PTEs did not differ in prodromal symptom severity. Explanations and implications for the findings are discussed. CONCLUSIONS: These findings suggest that the relationship between trauma and the development of psychotic symptoms extends to children and adolescents as young as 7 years of age. This study underscores the importance of screening for trauma exposure among youth seeking treatment for psychotic symptoms. PMID- 29575641 TI - NT-pro BNP-A marker for worsening respiratory status and mortality in infants and young children with pulmonary hypertension. AB - AIM: To evaluate predictors of morbidity and mortality in pediatric patients with pulmonary hypertension (PH), laboratory and echocardiographic measures of PH were analyzed. METHODS: A retrospective review of all infants and children < 2 years of age with PH from January 2011 to August 2016 was conducted. Correlations were determined using Spearman's rank correlation coefficients. Differences in characteristics between survivors and nonsurvivors were analyzed and Kaplan-Meier survival curves were generated. RESULTS: Of 56 patients, the majority were extremely premature; of African American ethnicity; and had bronchopulmonary dysplasia. Patients who died were more likely to have underlying congenital heart disease; have a higher increase in the concentration of carbon dioxide in the blood (pCO2 ) with a corresponding greater mean percentage decrease in pH and percentage rise in NT-pro BNP during PH exacerbations; more likely to have been on medications for pulmonary hypertension; and have a higher RVSP/SBP (%) ratio and S/D ratio. There were positive correlations between percentage rise in NT-pro BNP and pCO2 ; NT-pro BNP and RVSP/SBP (%) ratio; and RVSP/SBP (%) ratio and S/D ratio. CONCLUSIONS: Infants and young children with pulmonary hypertension have increased morbidity and mortality. NT-pro BNP is a useful biomarker for both respiratory exacerbations and mortality, and RVSP/SBP (%) ratio and S/D ratio are echocardiographic identifiers for increased mortality.

AB - We report the first total synthesis of (-)-17-nor-excelsinidine, a zwitterionic monoterpene indole alkaloid that displays an unusual N4-C16 connection. Inspired by the postulated biosynthesis, we explored an oxidative coupling approach from the geissoschizine framework to forge the key ammonium-acetate connection. Two strategies allowed us to achieve this goal, namely an intramolecular nucleophilic substitution on a 16-chlorolactam with the N4 nitrogen atom or a direct I2 mediated N4-C16 oxidative coupling from the enolate of geissoschizine. PMID- 29575643 TI - Creating a framework for the prioritization of biosecurity risks to the New Zealand dairy industry. AB - The New Zealand dairy sector relies on robust biosecurity measures to control and mitigate a wide range of threats to the industry. To optimize the prioritization of organisms and manage the risk they pose to the sector in a transparent and credible way, the Dairy Biosecurity Risk Evaluation Framework (D-BRiEF) was developed. This comprehensive framework was specifically designed for decision support, using a standardized approach to address the full spectrum of biosecurity threats to the sector, including exotic and endemic animal disease organisms, pest plants and insects. D-BRiEF is underpinned by three main processes, namely (i) hazard identification; (ii) multicriteria risk assessment; and (iii) communication for risk management. Expert knowledge and empirical data, including associated uncertainty, are harnessed in a standardized format. Results feed into a probability-impact model that was developed in close collaboration with dairy sector economists to provide overall comparative 10-year quantitative economic impact estimates for each assessed risk organism. A description of the overarching framework, which applies to diverse organism groups, is presented with detailed methodology on both endemic and exotic animal disease risk organisms. Examples of visual outputs are included, although actual ranking results are not reported due to industry confidentiality. D-BRiEF can provide a decision advantage to DairyNZ biosecurity risk managers and sector stakeholders by creating a transparent process that can be interrogated and updated at multiple levels to fully understand the layers of risk posed by different organisms. PMID- 29575644 TI - HLA-A*02:07 Allele Associates with Clarithromycin-Induced Cutaneous Adverse Drug Reactions in Chinese Patients. AB - Genetic risk factors could cause cutaneous adverse drug reactions (cADRs) in patients after treatment with clarithromycin. This study explored the association of HLA class I genes with clarithromycin-cADRs in Han Chinese patients. A total of 12 clarithromycin-cADR patients and 34 clarithromycin-tolerant controls were recruited for the high-resolution genotyping of HLA class I genes (HLA-A, HLA-B and HLA-C). The population controls consisted of 283 Han Chinese retrieved from the MHC database for validated comparison. A molecular docking analysis of HLA A*02:07 protein and clarithromycin was conducted using glide module with Schrodinger Suite. Among all tested HLA alleles, the carrier frequencies of HLA A*02:07 (58% versus 5.9%, OR = 22.40, 95% CI = 3.58-139.98, p = 8.20 * 10E-5, pc = 1.1 * 10E-3) and HLA-B*46:01 (50% versus 5.9%, OR = 16.00, 95% CI = 2.59-98.99, p = 0.002, pc = 0.03) were significantly higher in clarithromycin-cADRs than in clarithromycin-tolerant controls. However, when compared to population controls, only HLA-A*02:07, and not HLA-B*46:01, reached statistical significance (58% versus 15.5%, OR = 7.61, 95% CI = 2.31-25.04, p = 1.2 * 10E-4, pc = 1.7 * 10E-3). Furthermore, molecular docking data revealed that clarithromycin could bind to and interact with HLA-A*02:07 in two possible binding situations. These data suggest that HLA-A*02:07 might be a genetic risk factor for developing clarithromycin-cADRs in Han Chinese and serve as a useful biomarker for personalized medicine to prevent clarithromycin-cADRs. PMID- 29575645 TI - MiR-330-5p negatively regulates ovine preadipocyte differentiation by targeting branched-chain aminotransferase 2. AB - The differentiation of preadipocytes into adipose tissues is tightly regulated by various factors including microRNAs and cytokines. This article aims to study the effect of miR-330-5p on expression of BCAT2 in ovine preadipocytes. Ovine preadipocytes were isolated, and we found that the miR-330-5p expression decreased gradually during the early differentiation of ovine preadipocytes, while BCAT2 expression increased. BCAT2 was identified as a direct target of miR 330-5p, ectopic expression of miR-330-5p could change the expression of both BCAT2 mRNA and protein. Silencing BCAT2 had the same inhibition effects as overexpressing miR-330-5p on the preadipocyte differentiation, but overexpressing BCAT2 had the converse effects. Taken together, we demonstrated that miR-330-5p is a negative regulator of differentiation by targeting BCAT2, and clarified the role of BCAT2 and miR-330-5p during preadipocyte differentiation. PMID- 29575646 TI - Parental body mass index and blood pressure are associated with higher body mass index and blood pressure in their adult offspring: a cross-sectional study in a resource-limited setting in northern Peru. AB - OBJECTIVES: High body mass index (BMI) and blood pressure (BP) are major contributors to the high burden of non-communicable diseases in adulthood. Individual high-risk and population approaches for prevention require newer strategies to target these risk factors and focusing on the family to introduce prevention initiatives appears as a promising scenario. Characterisation of the relationship between BMI and BP among the adult members of a given family merits evaluation. We conducted a secondary analysis of an implementation study in Tumbes, Peru, benefiting from data derived from families with at least one adult offspring. METHODS: The exposures of interest were the BMI, systolic BP (SBP) and diastolic BP (DBP) of the mother and father. The outcomes were the BMI, SBP and DBP of the offspring. Mixed-effects linear regression models were conducted. RESULTS: The mean age of the offspring, mothers and fathers was 29 (SD: 9.5), 54 (SD: 11.8) and 59 (SD: 11.6) years, respectively. Father's BMI was associated with a quarter-point increase in offspring BMI, regardless of the sex of the offspring. Mother's BMI had a similar effect on the BMI of her sons, but had no significant effect on her daughters'. Mother's SBP was associated with almost one tenth of mmHg increase in the SBP of the adult offspring. There was no evidence of an association for DBP. CONCLUSIONS: In families with adult members, the higher the parents' BMI and SBP, the higher their adult offspring's levels will be. PMID- 29575647 TI - The influence of insurance type on stage at presentation, treatment, and survival between Asian American and non-Hispanic White lung cancer patients. AB - The effect of insurance type on lung cancer diagnosis, treatment, and survival in Asian patients living in the United States is still under debate. We have analyzed this issue using the Surveillance, Epidemiology, and End Results database. There were 102,733 lung cancer patients age 18-64 years diagnosed between 2007 and 2013. Multilevel regression analysis was performed to identify the association between insurance types, stage at diagnosis, treatment modalities, and overall mortality in Asian and non-Hispanic White (NHW) patients. Clinical characteristics were significantly different between Asian and NHW patients, except for gender. Asian patients were more likely to present with advanced disease than NHW patients (ORadj = 1.12, 95% CI = 1.06-1.19). Asian patients with non-Medicaid insurance underwent lobectomy more than NHW patients with Medicaid or uninsured; were more likely to undergo mediastinal lymph node evaluation (MLNE) (ORadj = 1.98, 95% CI = 1.72-2.28) and cancer-directed surgery and/or radiation therapy (ORadj = 1.41, 95% CI = 1.20-1.65). Asian patients with non-Medicaid insurance had the best overall survival. Uninsured or Medicaid covered Asian patients were more likely to be diagnosed with advanced disease, less likely to undergo MLNE and cancer-directed treatments, and had shorter overall survival than their NHW counterpart. PMID- 29575649 TI - Detection and pharmacokinetics of grapiprant following oral administration to exercised Thoroughbred horses. AB - Traditional therapeutic options for the treatment of lameness associated with inflammation in performance horses include administration of cyclooxygenase enzyme inhibiting non-steroidal anti-inflammatory drugs (NSAID). As long-term use of these drugs can adversely impact the health of the horse, anti-inflammatories with a more favorable safety profile are warranted. Grapiprant is a newly approved non-cyclooxygenase inhibiting NSAID that has demonstrated efficacy and safety in other species and which may be a valuable alternative to traditional NSAIDs used in the horse. The objectives of the current study were to describe drug concentrations and the pharmacokinetics of grapiprant in exercised Thoroughbred horses and to develop an analytical method that could be used to regulate its use in performance horses. To that end, grapiprant, at a dose of 2 mg/kg was administered orally to 12 exercised Thoroughbred horses. Blood and urine samples were collected prior to and for up to 96 hours post drug administration. Drug concentrations were measured using liquid chromatography tandem mass spectrometry. Grapiprant remained above the LOQ of the assay (0.005 ng/mL) in serum for 72 hours post administration and urine concentrations were above the LOQ until 96 hours. The Cmax , Tmax and elimination half-life were 31.9 +/- 13.9 ng/mL, 1.5 +/- 0.5 hours and 5.86 +/- 2.46 hours, respectively. The drug was well tolerated in all horses at a dose of 2 mg/kg. Results support further study of this compound in horses. Furthermore, development of a highly sensitive analytical method demonstrate that this compound can be adequately regulated in performance horses.

The Sleeping Beauty (SB) transposon-based glioma mouse model allows for effective in vivo analysis of candidate genes. In the present study, we developed a transposon vector that encodes the triple combination of platelet-derived growth factor subunit A (PDGFA), and shRNAs against Nf1 and Trp53 (shNf1/shp53). Initiation and progression of glioma in the brain were monitored by expression of a fluorescent protein. Transduction of the vector into neural progenitor and stem cells (NPC) in the subventricular zone (SVZ) of the neonatal brain induced proliferation of oligodendrocyte precursor cells, and promoted formation of highly penetrant malignant gliomas within 2-4 months. Cells isolated from the tumors were capable of forming secondary tumors. Two transposon vectors, encoding either PDGFA or shNf1/shp53 were co-electroporated into NPC. Cells expressing PDGFA or shNf1/shp53 were labeled with unique fluorescent proteins allowing visualization of the spatial distribution of cells with different genetic alterations within the same tumor. Tumor cells located at the center of tumors expressed PDGFA at higher levels than those located at the periphery, indicating that intratumoral heterogeneity in PDGFA expression levels spontaneously developed within the same tumor. Tumor cells comprising the palisading necrosis strongly expressed PDGFA, suggesting that PDGFA signaling is involved in hypoxic responses in glioma. The transposon vectors developed are compatible with any genetically engineered mouse model, providing a useful tool for the functional analysis of candidate genes in glioma.

AB - Precise replacement of an existing allele in commercial cultivars with an elite allele is a major goal in crop breeding. A single nucleotide polymorphism in the NRT1.1B gene between japonica and indica rice is responsible for the improved nitrogen use efficiency in indica rice. Herein, we precisely replaced the japonica NRT1.1B allele with the indica allele, in just one generation, using CRISPR/Cas9 gene-editing technology. No additional selective pressure was needed to enrich the precise replacement events. This work demonstrates the feasibility of replacing any genes with elite alleles within one generation, greatly expanding our ability to improve agriculturally important traits. PMID- 29575651 TI - C-reactive protein is an independent prognostic marker in patients with tongue carcinoma - A retrospective study. AB - OBJECTIVES: Reliable prognostic markers are lacking for tongue carcinoma. C reactive protein (CRP) and a ratio from neutrophils/lymphocytes (NLR) are biomarkers, associated with prognosis in solid cancers. Aim of this work was to investigate the role of CRP and NLR in prognosis of patients with tongue carcinoma. DESIGN: Retrospective cohort study. SETTING: We retrospectively analysed data of patients treated for tongue carcinoma at our institution. Levels of CRP, Neutrophils and Lymphocytes were measured pretherapeutic. PARTICIPANTS: 197 patients treated for squamous cell carcinoma of the tongue between 2002 and 2015. MAIN OUTCOME MEASURES: Overall survival, disease-free survival. RESULTS: Elevated CRP was significantly associated with shorter overall survival in our cohort in uni- and multivariate analysis. NLR was not associated with prognosis. CONCLUSION: In the present study we could confirm the role of CRP as an independent prognostic marker in patients with tongue carcinoma. Incorporating this marker in prognostication could represent a valuable and moreover inexpensive tool for improved decisions making concerning therapy in the future. PMID- 29575652 TI - Noninvasive evaluation of cerebrospinal fluid pressure in ocular hypertension: a preliminary study. AB - PURPOSE: To compare the orbital cerebral spinal fluid pressure (CSFP) and trans lamina cribrosa pressure difference (TLCPD) determined noninvasively in ocular hypertensive (OH) subjects and controls. METHODS: Cross-sectional observational study. Magnetic resonance imaging was used to measure orbital subarachnoid space width (OSASW). The CSFP (mm Hg) was estimated from a published formula as 17.54 * MRI derived OSASW at 15 mm behind the globe + 0.47 * body mass index + 0.13 * mean arterial blood pressure -21.52. Estimated TLCPD was calculated as IOP- CSFP. RESULTS: The orbital subarachnoid space width was significantly wider (p = 0.01) in the OH group than in the control group at all three measurement locations. The MRI derived CSFP value in OH (14.9 +/- 2.9 mm Hg) was significantly higher than in the normal group (12.0 +/- 2.8 mm Hg; p < 0.01). The estimated TLCPD value in OH (9.0 +/- 4.2 mm Hg) was significantly higher than in controls (3.6 +/- 3.0 mm Hg; p < 0.01). CONCLUSION: The wider OSASW and higher estimated CSFP in OH subjects suggest a higher orbital CSFP. Despite a higher orbital CSFP that could be protective, the higher TLCPD in OH may play a significant role in the risk of developing glaucoma. PMID- 29575653 TI - Transition-Metal-Based Electrocatalysts as Cocatalysts for Photoelectrochemical Water Splitting: A Mini Review. AB - Converting solar energy into hydrogen via photoelectrochemical (PEC) water splitting is one of the most promising approaches for a sustainable energy supply. Highly active, cost-effective, and robust photoelectrodes are undoubtedly crucial for the PEC technology. To achieve this goal, transition-metal-based electrocatalysts have been widely used as cocatalysts to improve the performance of PEC cells for water splitting. Herein, this Review summarizes the recent progresses of the design, synthesis, and application of transition-metal-based electrocatalysts as cocatalysts for PEC water splitting. Mo, Ni, Co-based electrocatalysts for the hydrogen evolution reaction (HER) and Co, Ni, Fe-based electrocatalysts for the oxygen evolution reaction (OER) are emphasized as cocatalysts for efficient PEC HER and OER, respectively. Particularly, some most efficient and robust photoelectrode systems with record photocurrent density or durability for the half reactions of HER and OER are highlighted and discussed. In addition, the self-biased PEC devices with high solar-to-hydrogen efficiency based on earth-abundant materials are also addressed. Finally, this Review is concluded with a summary and remarks on some challenges and opportunities for the further development of transition-metal-based electrocatalysts as cocatalysts for PEC water splitting. PMID- 29575654 TI - Spermidine promotes nucleus pulposus autophagy as a protective mechanism against apoptosis and ameliorates disc degeneration. AB - Spermidine has therapeutic effects in many diseases including as heart diastolic function, myopathic defects and neurodegenerative disorders via autophagy activation. Autophagy has been found to mitigate cell apoptosis in intervertebral disc degeneration (IDD). Accordingly, we theorize that spermidine may have beneficial effects on IDD via autophagy stimulation. In this study, spermidine's effect on IDD was evaluated in tert-butyl hydroperoxide (TBHP)-treated nucleus pulposus cells of SD rats in vitro as well as in a puncture-induced rat IDD model. We found that autophagy was actuated by spermidine in nucleus pulposus cells. In addition, spermidine treatment weakened the apoptotic effects of TBHP in nucleus pulposus cells. Spermidine increased the expression of anabolic proteins including Collagen-II and aggrecan and decreased the expression of catabolic proteins including MMP13 and Adamts-5. Additionally, autophagy blockade using 3-MA reversed the beneficial impact of spermidine against nucleus pulposus cell apoptosis. Autophagy was thus important for spermidine's therapeutic effect on IDD. Spermidine-treated rats had an accentuated T2-weighted signal and a diminished histological degenerative grade than vehicle-treated rats, showing that spermidine inhibited intervertebral disc degeneration in vivo. Thus, spermidine protects nucleus pulposus cells against apoptosis through autophagy activation and improves disc, which may be beneficial for the treatment of IDD. PMID- 29575655 TI - Potential implications of a more timely living kidney donor evaluation. AB - Living donor kidney transplantation is the most promising way to avoid or minimize the amount of time a recipient spends on dialysis before transplantation. We studied 887 living kidney donors at 5 transplant centers in Ontario, Canada, who started their evaluation and donated between April 2006 and March 2014. Using a series of hypothetical scenarios, we estimated the impact of an earlier living donor evaluation completion and donation on the number pre emptive transplants, the time spent on dialysis, healthcare cost savings from averted dialysis costs (CAD $2016), and the number of additional transplants. During the study period, if the donor transplants occurred 3 months earlier, the healthcare system would save on average $12 055 (standard deviation [SD] $13 594) per recipient; 21 recipients could have avoided dialysis altogether, and 57 additional transplants (a 26% increase) could have occurred each year. For the 220 living kidney donor transplants performed in Ontario, Canada, each year, this translates to a total annual cost savings of $2.7M. In conclusion, a more timely evaluation of living donor candidates and their intended recipients may increase the supply of kidneys for transplantation. Improved evaluation efficiency may also yield more pre-emptive transplants and substantial healthcare cost savings through averted dialysis costs. PMID- 29575656 TI - Comparison of Power, Prognosis, and Extrapolation Properties of Four Population Pharmacodynamic Models of HbA1c for Type 2 Diabetes. AB - Reusing published models saves time; time to be used for informing decisions in drug development. In antihyperglycemic drug development, several published HbA1c models are available but selecting the appropriate model for a particular purpose is challenging. This study aims at helping selection by investigating four HbA1c models, specifically the ability to identify drug effects (shape, site of action, and power) and simulation properties. All models could identify glucose effect nonlinearities, although for detecting the site of action, a mechanistic glucose model was needed. Power was highest for models using mean plasma glucose to drive HbA1c formation. Insulin contribution to power varied greatly depending on the drug target; it was beneficial only if the drug target was insulin secretion. All investigated models showed good simulation properties. However, extrapolation with the mechanistic model beyond 12 weeks resulted in drug effect overprediction. This investigation aids drug development in decisions regarding model choice if reusing published HbA1c models. PMID- 29575657 TI - Consensus on procedures to include in a simulation-based curriculum in ophthalmology: a national Delphi study. AB - PURPOSE: The number of available simulation-based models for technical skills training in ophthalmology is rapidly increasing, and development of training programmes around these procedures should follow a structured approach. The aim of this study was to identify all technical procedures that should be integrated in a simulation-based curriculum in ophthalmology. METHODS: Key opinion leaders involved in the education of ophthalmologists in Denmark including heads of departments, heads of clinical education, professors and board members of the society were invited to participate in a three-round Delphi process. Round 1 aimed at identifying technical procedures that physicians should be able to perform competently when completing specialty training; round 2 involved characterization of each procedure including frequency, number of operators, risk and/or discomfort for patients associated with an inexperienced physician, and feasibility of simulation-based training; round 3 included a priority ranking of procedures. RESULTS: The response rate for each round was 71%, 64% and 64%, respectively. Sixty-five procedures were reduced to 25 prioritized procedures during the three rounds. Two-thirds of the procedures that were identified and highly prioritized were therapeutic procedures such as intravitreal injection therapy, yttrium-aluminium-garnet laser iridotomy/capsulotomy, minor ocular surface procedures and retinal argon laser therapy. The diagnostic procedures that were prioritized were ocular ultrasound, superficial keratectomy and optical coherence tomography (OCT). CONCLUSION: The Delphi process identified and prioritized 25 procedures that should be practised in a simulation-based environment to achieve competency before working with patients. The list may be used to guide the development of future training programmes for ophthalmologists. PMID- 29575658 TI - Metabolic traits predict the effects of warming on phytoplankton competition. AB - Understanding how changes in temperature affect interspecific competition is critical for predicting changes in ecological communities with global warming. Here, we develop a theoretical model that links interspecific differences in the temperature dependence of resource acquisition and growth to the outcome of pairwise competition in phytoplankton. We parameterised our model with these metabolic traits derived from six species of freshwater phytoplankton and tested its ability to predict the outcome of competition in all pairwise combinations of the species in a factorial experiment, manipulating temperature and nutrient availability. The model correctly predicted the outcome of competition in 72% of the pairwise experiments, with competitive advantage determined by difference in thermal sensitivity of growth rates of the two species. These results demonstrate that metabolic traits play a key role in determining how changes in temperature influence interspecific competition and lay the foundation for mechanistically predicting the effects of warming in complex, multi-species communities.

PMID- 29575660 TI - Subthreshold social cognitive deficits may be a key to distinguish 22q11.2DS from schizophrenia. AB - AIM: Social cognitive impairments are core features in 22q11.2 deletion syndrome (22q11.2DS) and schizophrenia (SCZ). Indeed, adults with 22q.11.2 DS often have poorer social competence as well as poorer performance on measures of social cognitive skills (emotion recognition and theory of mind, ToM) compared with typically developing people. However, studies comparing specific social cognitive components in 22q11.2DS and SCZ have not yet been widely conducted. METHODS: In this study we compared performances of 22q11.2DS and SCZ on both facial emotion recognition and ToM. Patients with 22q11.2DS (n = 18) and matched SCZ patients were recruited. After neuropsychological testing, the facial emotion recognition test assessed the patients' ability to recognize six basic, universal emotions (joy, anger, sadness, fear, disgust, and contempt). The Versailles-situational intentional reading evaluated ToM with six scenes from movies showing characters in complex interactions (involving hints, lies, and indirect speech). RESULTS: We show that 22q11.2DS exhibited significantly lower performance in emotion recognition than SCZ patients did, especially for disgust, contempt, and fear. This impairment seems to be a core cognitive phenotype in 22q11.2DS, regardless of the presence of SCZ symptoms. Concerning ToM, our results may highlight the same impairment level in 22q11.2DS and SCZ but require to be replicated in a larger cohort. CONCLUSION: Our results document the existence of threshold social cognitive deficits distinguishing 22q11.2DS from SCZ. PMID- 29575661 TI - Early diagnosis of infection occurs in burned patients and verification in vitro. AB - OBJECTIVE: To explore the trend of CD64+ neutrophils being present in the peripheral blood of patients with burns and verification in vitro. METHOD: We isolated and purified CD64+ neutrophils from healthy people, stimulated cells with inactivated Staphylococcus aureus in vitro to make them proliferate and analyzed them with Modfit 2 analysis software. Patients with burns were divided into two groups, depending on whether there was a complicated infection or not, and 35 healthy participants were enrolled as blank group. WBC and CD64+ neutrophil counts were detected and then analyzed the specificity and sensitivity according to the ROC curve. RESULTS: The proliferation index of the CD64+ cells in the experimental wells was significantly higher than that in the control wells (P < .05). The CD64+ cell counts in the peripheral blood of patients in the infection group were significantly higher than patients without infection, but also higher than the healthy people (P < .05). The sensitivity and specificity of CD64+ cellular diagnosis for burn infection were 94.2% and 76.8%, respectively, according to the ROC curve, which were significantly better than those of the WBCs. CONCLUSION: CD64+ cells in the peripheral blood of patients with burns complicated by infection increased significantly, and thus, it can be regarded as an early diagnostic indicator of burns with a concurrent infection.

AB - This paper, on writing research questions, is the first in a series that aims to support novice researchers within clinical education, particularly those undertaking their first qualitative study. Put simply, a research question is a question that a research project sets out to answer. Most research questions will lead to a project that aims to generate new insights, but the target audience and the methodology will vary widely. The term 'evaluation question' is used less commonly, but the same principles apply. The key difference is that evaluation questions are typically more focused on the immediate context: for example, the effectiveness of an educational intervention in a particular setting. Whether your ambition is for research or evaluation, we hope that you will find this paper helpful for designing your own educational projects. A research question is a question that a research project sets out to answer. PMID- 29575668 TI - Early management of patients with medication-overuse headache: results from a multicentre clinical study. AB - BACKGROUND AND PURPOSE: Educational intervention has proved to be effective in reducing drug abuse in uncomplicated medication-overuse headache (MOH). This ancillary of the SAMOHA multicentre study aimed to assess any differences in phenotypic characteristics, type and amount of drugs overused, and comorbidities between patients with MOH who responded to simple advice and those who did not. METHODS: Demographic and clinical headache data of the last 3 months before enrollment of patients were collected and patients were then asked to fill out a daily headache diary for 4 weeks. Patients were then divided into two subgroups, i.e. those with confirmed MOH continued in the study [randomized (R) group], whereas those who did not still show any features of MOH dropped out of the study. RESULTS: A total of 88 (67.7%) patients still met the inclusion criteria after the baseline 4 weeks (R group). Conversely, 42 (32.3%) patients dropped out of the study. A detailed analysis of those who dropped out revealed that only 34 were not randomized at visit 2 because they no longer satisfied the inclusion criteria for MOH [screening failures (SF) group]. The SF group was significantly younger and had fewer years of migraine history than the R group. Moreover, the SF group had a significantly shorter history of chronicity compared with the R group. CONCLUSIONS: Our findings suggest that in MOH trials, after an educational session, an observational period is needed in order to confirm the diagnosis of MOH and to avoid overestimation of the effect of other treatments used to manage MOH. Future research should focus mainly on those patients with MOH who do not respond to simple advice and with unsuccessful withdrawal. PMID- 29575669 TI - Comparison of a prepCheck-supported self-assessment concept with conventional faculty supervision in a pre-clinical simulation environment. AB - OBJECTIVES: This study aimed to evaluate the educational outcome of a digitally based self-assessment concept (prepCheck; DentsplySirona, Wals, Austria) for pre clinical undergraduates in the context of a regular phantom-laboratory course. MATERIALS AND METHODS: A sample of 47 third-year dental students participated in the course. Students were randomly divided into a prepCheck-supervised (self assessment) intervention group (IG; n = 24); conventionally supervised students constituted the control group (CG; n = 23). During the preparation of three surface (MOD) class II amalgam cavities, each IG participant could analyse a superimposed 3D image of his/her preparation against the "master preparation" using the prepCheck software. In the CG, several course instructors performed the evaluations according to pre-defined assessment criteria. After completing the course, a mandatory (blinded) practical examination was taken by all course participants (both IG and CG students), and this assessment involved the preparation of a MOD amalgam cavity. Then, optical impressions by means of a CEREC-Omnicam were taken to digitalize all examination preparations, followed by surveying and assessing the latter using prepCheck. RESULTS: The statistical analysis of the digitalized samples (Mann-Whitney U test) revealed no significant differences between the cavity dimensions achieved in the IG and CG (P = .406). Additionally, the sum score of the degree of conformity with the "master preparation" (maximum permissible 10% of plus or minus deviation) was comparable in both groups (P = .259). CONCLUSION: The implemented interactive digitally based, self-assessment learning tool for undergraduates appears to be equivalent to the conventional form of supervision. Therefore, such digital learning tools could significantly address the ever-increasing student to faculty ratio. PMID- 29575670 TI - Special Issue: Cheminformatics in Drug Discovery.

PMID- 29575671 TI - Rituximab May Cause Increased Hepatitis C Virus Viremia in Rheumatoid Arthritis Patients Through Declining Exosomal MicroRNA-155. AB - OBJECTIVE: Several studies have shown that rituximab may enhance hepatitis C virus (HCV) activity. MicroRNAs (miRNAs) have been implicated in modulating the host immune response in HCV infection; miRNAs can be packaged into the exosomes and then shuttled by the exosomes to aid biologic functions. However, the role of exosomal miRNAs (exo-miRNAs) in rituximab-related HCV activity enhancement remains unclear. METHODS: The association between rituximab and increased HCV activity was examined using an in vitro cell-based assay. Purified exosomes were confirmed using immunoblotting and flow cytometry and quantified using enzyme linked immunosorbent assay. Exosomal miRNA-155 (exo-miR-155) levels were measured using quantitative reverse transcription-polymerase chain reaction. RESULTS: In vitro data showed that B cell-derived miR-155 could inhibit HCV replication in hepatocytes through exosome transmission. Rituximab could both induce B cell depletion and affect intracellular miR-155 production as well as exo-miR-155 transmission and then enhance HCV activity in hepatocytes (P < 0.005). Serum exosome levels were increased in rheumatoid arthritis (RA) patients with HCV infection compared with the levels in RA patients without HCV infection (P < 0.01). The exo-miR-155 levels were significantly increased in RA patients with HCV infection compared with those without infection (P < 0.01). A significantly greater decrement of exo-miR-155 expression was observed after rituximab therapy compared with those observed before therapy (P < 0.01), and hepatitis C viral loads increased simultaneously (P < 0.05). CONCLUSION: Circulating exo-miR-155 levels were negatively correlated with hepatitis C viral loads and subsequently associated with rituximab-related HCV activity enhancement in RA patients. Exo miR-155 may become a potential diagnostic biomarker or therapeutic target. PMID- 29575672 TI - Serological evidence of widespread exposure of Grenada fruit bats to chikungunya virus. AB - Antibody detection against selected potentially zoonotic vector-borne alphaviruses and flaviviruses was conducted on sera from bats from all six parishes in Grenada, West Indies. Sera were tested for (i) antibodies to flaviviruses West Nile virus, St. Louis encephalitis virus, Ilheus virus, Bussuquara virus (BSQV), Rio Bravo virus and all four serotypes of dengue virus (DENV) by plaque reduction neutralization test (PRNT); (ii) antibodies to alphaviruses western equine encephalitis virus, Venezuelan equine encephalitis virus and eastern equine encephalitis virus by epitope-blocking enzyme-linked immunosorbent assay (ELISA); and (iii) antibodies to the alphavirus chikungunya (CHIKV) by PRNT. Two species of fruit bats were sampled, Artibeus jamaicensis and Artibeus lituratus, all roosting in or within 1,000 m of human settlements. Fifteen (36%) of the 42 bats tested for neutralizing antibodies to CHIKV were positive. The CHIKV-seropositive bats lived in localities spanning five of the six parishes. All 43 bats tested for epitope-blocking ELISA antibody to the other alphaviruses were negative, except one positive for Venezuelan equine encephalitis virus. All 50 bats tested for neutralizing antibody to flaviviruses were negative, except one that had a BSQV PRNT80 titre of 20. The CHIKV serology results indicate that bats living close to and within human settlements were exposed to CHIKV in multiple locations. Importantly, bats for this study were trapped a year after the introduction and peak of the human CHIKV epidemic in Grenada. Thus, our data indicate that bats were exposed to CHIKV possibly during a time of marked decline in human cases. PMID- 29575673 TI - Determining One-Year Trajectories of Low-Back-Related Leg Pain in Primary Care Patients: Growth Mixture Modeling of a Prospective Cohort Study. AB - OBJECTIVE: The clinical presentation and outcome of patients with back and leg pain in primary care are heterogeneous and may be better understood by identification of homogeneous and clinically meaningful subgroups. Subgroups of patients with different back pain trajectories have been identified, but little is known about the trajectories for patients with back-related leg pain. This study sought to identify distinct leg pain trajectories, and baseline characteristics associated with membership of each group, in primary care patients. METHODS: Monthly data on leg pain intensity were collected over 12 months for 609 patients participating in a prospective cohort study of adult patients seeking health care for low-back and leg pain, including sciatica, of any duration and severity, from their general practitioner. Growth mixture modeling was used to identify clusters of patients with distinct leg pain trajectories. Trajectories were characterized using baseline demographic and clinical examination data. Multinomial logistic regression was used to predict latent class membership, with a range of covariates. RESULTS: Four patient clusters were identified: improving mild pain (58%), persistent moderate pain (26%), persistent severe pain (13%), and improving severe pain (3%). Clusters showed statistically significant differences in a number of baseline characteristics. CONCLUSION: Four trajectories of leg pain were identified. Clusters 1, 2, and 3 were generally comparable to back pain trajectories, while cluster 4, with major improvement in pain, is infrequently identified. Awareness of such distinct patient groups improves understanding of the course of leg pain and may provide a basis of classification for intervention. PMID- 29575674 TI - Dentin dysplasia type I-A dental disease with genetic heterogeneity. AB - Hereditary dentin disorders include dentinogenesis imperfecta (DGI) and dentin dysplasia (DD), which are autosomal dominant diseases characterized by altered dentin structure such as abnormality in dentin mineralization and the absence of root dentin. Shields classified DGI into three subgroups and DD into two subtypes. Although they are all hereditary dentin diseases, they do not share the same causative genes. To date, the pathogenic genes of DGI type I, which is considered a clinical manifestation of syndrome osteogenesis imperfecta, include COL1A1 and COL1A2. Mutations of the DSPP gene, which encodes the dentin sialophosphoprotein, a major non-collagenous protein, are responsible for three isolated dentinal diseases: DGI-II, DGI-III, and DD-II. However, DD-I appears to be special in that researchers have found three pathogenicity genes-VPS4B, SSUH2, and SMOC2-in three affected families from different countries. It is believed that DD-I is a genetically heterogeneous disease and is distinguished from other types of dentin disorders. This review summarizes the DD-I literature in the context of clinical appearances, radiographic characteristics, and functions of its pathogenic genes and aims to serve clinicians in further understanding and diagnosing this disease. PMID- 29575675 TI - Novel oral anticoagulant use in adult Fontan patients: A single center experience. AB - OBJECTIVE: Adult Fontan patients are at increased risk for thrombosis and thromboembolic complications leading to increased morbidity and mortality. Most are prescribed antiplatelet or anticoagulant therapy for thromboprophylaxis; novel oral anticoagulants (NOACs) are uncommonly used given lack of data on their use in this population and generalized concerns regarding Fontan patients' abnormal coagulation. We report the largest single-center experience with the use of NOACs for treatment and prophylaxis of thrombosis and thromboembolism in adult Fontan patients. RESULTS: A retrospective chart review identified 21 patients (11 female, 10 male), median age 33 years (18-50) at first initiation, who were prescribed a NOAC on 27 different occasions. The main indications for anticoagulation were arrhythmia (N = 12), thrombosis (N = 8), and persistent right to left shunts (N = 2); one patient was initially on anticoagulation for arrhythmia but restarted for thrombosis. The most common indications for initiation of a NOAC over warfarin were patient/provider preference (N = 11), labile international normalized ratio (INR) (N = 5), initiation of therapy elsewhere (N = 3), and history of poor clinical follow-up (N = 2). Over a cumulative 316 months of patient therapy, one new thrombotic event was noted. No major or nonmajor bleeding events occurred, and 10 patients experienced minor bleeding that did not require the cessation of therapy. One patient died from multiorgan system failure following an unwitnessed, out of hospital arrest. At present, 10 patients remain on NOAC therapy in the setting of ongoing arrhythmia (N = 4), history of stroke (N = 2), history of pulmonary embolism (N = 2), history of deep vein thrombosis (N = 1), and history of right ventricle thrombus (N = 1). CONCLUSIONS: While our study is limited by size, our results suggest that NOACs may be a non-inferior alternative to traditional anticoagulation and that further study is warranted. PMID- 29575676 TI - Ocular microcirculation measurement with laser speckle flowgraphy and optical coherence tomography angiography in glaucoma. AB - PURPOSE: To compare glaucoma severity with ocular microcirculation, measured with either laser speckle flowgraphy (LSFG) or optical coherence tomography angiography (OCTA). METHODS: We retrospectively studied 82 eyes of 82 open-angle glaucoma (OAG) patients who underwent same-day LSFG and OCTA examinations, with 20 eyes of 20 healthy subjects as controls. In OCTA images, vessel density (VD) (%) was calculated in concentric regions (regions 1, 2 and 3: R1, R2 and R3, respectively) defined by 1.6-, 3.2- and 3.6-mm-diameter circles around the optic nerve head (ONH). In R3, the large vessels were automatically masked to calculate pure capillary density (auto R3 VD). LSFG-measured mean blur rate (MBR) was examined in the overall ONH (MA), vessel-area ONH (MV) and tissue-area ONH (MT). RESULTS: Auto R3 VD had high reproducibility (coefficient of variation: 1.65 3.88%) and accurately reflected manual R3 VD [mean bias: -0.0087% (auto R3 VD - manual R3 VD)]. MA and MT decreased significantly with OAG severity, especially in the early OAG stages (control vs. mild: p = 0.003 and p < 0.001, respectively). R1 VD did not change with severity. R2 and auto R3 VD decreased significantly with OAG severity, especially in the severe stages (R2, mild vs. severe: p = 0.008; auto R3 VD, mild vs. severe: p < 0.001, moderate vs. severe: p = 0.028). CONCLUSION: Optical coherence tomography angiography-derived auto R3 VD is novel, reproducible and accurately reflects manual measurements. It is useful for differentiating moderate and advanced glaucoma, while LSFG-derived MT is useful for identifying early glaucoma. PMID- 29575677 TI - Vitamin D Analogues Tacalcitol and Calcipotriol Inhibit Proliferation and Migration of T98G Human Glioblastoma Cells. AB - The active form of vitamin D (1alpha,25-dihydroxyvitamin D) acts as a steroid hormone and binds to the vitamin D receptor. This receptor is expressed in most cell types including cells in the central nervous system (CNS). Vitamin D has several functions in the body including effects on brain development, neuroprotection and immunological regulation. It has been shown that vitamin D has antiproliferative activities in different cancer cell lines. Tacalcitol and calcipotriol are synthetic analogues of 1alpha,25-dihydroxyvitamin D with reduced effect on calcium metabolism. The aim of this study was to analyse the effects of tacalcitol and calcipotriol on cell viability, proliferation and migration in the human glioblastoma cell line T98G. Glioblastoma is the most lethal type of primary tumours in the CNS. Both analogues decreased cell viability and/or growth, dose-dependently, in concentrations between 1 nM and 10 MUM. Manual counting indicated suppressive effects by the vitamin D analogues on proliferation. Treatment with tacalcitol strongly suppressed thymidine incorporation, indicating that the vitamin D analogues mainly inhibit proliferation. Also, effects on cell migration were measured with wound-healing assay. Both calcipotriol and tacalcitol reduced the migration rate of T98G cells compared to vehicle-treated cells. However, they had no effect on caspase-3 and 7 activities, suggesting that their mechanism of action does not involve induction of apoptosis. The current results indicate that the vitamin D analogues tacalcitol and calcipotriol strongly reduce proliferation and migration of human glioblastoma T98G cells, suggesting a potential role for this type of compounds in treatment of brain cancer. PMID- 29575678 TI - Impact of percutaneous femoral arteriotomy closure using the MANTATM device on vascular and bleeding complications after transcatheter aortic valve replacement. AB - OBJECTIVES: To evaluate the feasibility of fully percutaneous closure using a novel collagen-based vascular closure device after transfemoral aortic valve replacement (TAVR). BACKGROUND: TAVR is utilized increasingly for the treatment of severe symptomatic aortic stenosis. Vascular complications related to access and closure dominate the adverse event profile of the procedure despite progressively reducing arteriotomy caliber. The advent of a novel collagen-based device (MANTATM ) and preliminary data suggest this could be used as a routine percutaneous closure device. METHODS: A prospective observational study of unselected consecutive patients undergoing TAVR in a single center. Data were collected via hospital electronic records and the SWEDEHEART registry. The primary clinical outcome was closure success and time to hemostasis. Secondary outcomes included VARC-2 defined major and minor vascular and bleeding complications within 30 days using suture-based closure with Prostar-XL within the same center. RESULTS: A consecutive cohort of 346 patients underwent TAVR via the transfemoral approach. Vascular closure with MANTATM was successful in all with a mean time to hemostasis of 42 sec (SD 115.5, range 0-600). The composite of all-cause mortality and major complications related to the main access site was similar between the groups (1.1% vs 1.9%, P = .61). Major bleeding occurred less frequently with MANTA TM (1.1% vs 7.8%, P = .02). CONCLUSION: The novel use of a collagen-based vascular closure device for large caliber arteriotomy is feasible in an unselected population undergoing transfemoral TAVR and appears efficacious compared to percutaneous suture-based closure. These data should prompt larger studies to evaluate efficacy and safety.

AB - Phosphorus (P) cycling is a fundamental process driven by microorganisms, and plants can regulate P cycling directly or via their influence on the soil microbial community. However, the differential P cycling patterns associated with legumes and grass are largely unknown. Therefore, we investigated the microbial community involved in P cycling in subtropical soil grown with stylo (Stylosanthes guianensis, legume) or bahiagrass (Paspalum notatum, grass) using metagenomic sequencing. P fractionation indicated that sparingly soluble inorganic P (Pi) accounted for approximately 75% of P pool. Bacteria involved in sparingly soluble Pi solubilization (pqq, gad, JEN) were more abundant in bahiagrass soil, with Candidatus Pelagibacter, Trichodesmium, Neorickettsia, Nitrobacter, Paraburkholderia, Candidatus Solibacter, Burkholderia as major contributors. In contrast, bacteria involved in organic P (Po) mineralization (php, glpQ, phn) were more abundant in stylo soil, consistent with phosphatase activity and Frankia, Kyrpidia, Thermobispora, Streptomyces, Rhodococcus were major contributors. Bacteria taking up low molecular-weight Po were more abundant in stylo soil than in bahiagrass soil, while those taking up Pi were less abundant. These data suggest that bacterial communities associated with legumes and grass develop contrasting P acquisition strategies, highlighting the possibility of intercropping with legumes and grass for better P cycling.

AB - The projected rise in global mean sea levels places many freshwater turtle species at risk of saltwater intrusion into freshwater habitats. Freshwater turtles are disproportionately more threatened than other taxa; thus, understanding the role of salinity in determining their contemporary distribution and evolution should be a research priority. Freshwater turtles are a slowly evolving lineage; however, they can adapt physiologically or behaviourally to various levels of salinity and, therefore, temporarily occur in marine or brackish environments. Here, we provide the first comprehensive global review on freshwater turtle use and tolerance of brackish water ecosystems. We link together current knowledge of geographic occurrence, salinity tolerance, phylogenetic relationships, and physiological and behavioural mechanisms to generate a baseline understanding of the response of freshwater turtles to changing saline environments. We also review the potential origins of salinity tolerance in freshwater turtles. Finally, we integrate 2100 sea level rise (SLR) projections, species distribution maps, literature gathered on brackish water use, and a phylogeny to predict the exposure of freshwater turtles to projected SLR globally. From our synthesis of published literature and available data, we build a framework for spatial and phylogenetic conservation prioritization of coastal freshwater turtles. Based on our literature review, 70 species (~30% of coastal freshwater turtle species) from 10 of the 11 freshwater turtle families have been reported in brackish water ecosystems. Most anecdotal records, observations, and descriptions do not imply long-term salinity tolerance among freshwater turtles. Rather, experiments show that some species exhibit potential for adaptation and plasticity in physiological, behavioural, and life-history traits that enable them to endure varying periods (e.g. days or months) and levels of saltwater exposure. Species that specialize on brackish water habitats are likely to be vulnerable to SLR because of their exclusive coastal distributions and adaptations to a narrow range of salinities. Most species, however, have not been documented in brackish water habitats but may also be highly vulnerable to projected SLR. Our analysis suggests that approximately 90% of coastal freshwater turtle species assessed in our study will be affected by a 1-m increase in global mean SLR by 2100. Most at risk are freshwater turtles found in New Guinea, Southeast Asia, Australia, and North and South America that may lose more than 10% of their present geographic range. In addition, turtle species in the families Chelidae, Emydidae, and Trionychidae may experience the greatest exposure to projected SLR in their present geographic ranges. Better understanding of survival, growth, reproductive and population-level responses to SLR will improve region-specific population viability predictions of freshwater turtles that are increasingly exposed to SLR. Integrating phylogenetic, physiological, and spatial frameworks to assess the effects of projected SLR may improve identification of vulnerable species, guilds, and geographic regions in need of conservation prioritization. We conclude that the use of brackish and marine environments by freshwater turtles provides clues about the evolutionary processes that have prolonged their existence, shaped their unique coastal distributions, and may prove useful in predicting their response to a changing world.

AB - OBJECTIVE: While long-term outcome following a first psychotic episode is well studied in schizophrenia (SZ), schizoaffective disorder (SA), and bipolar disorder (BD), major depressive disorder with psychotic features (MDDP) has received less investigation. This study compares MDDP with SZ, SA, and BD at 6 year follow-up. METHODS: At 6 years after a first psychotic episode, follow-up data on psychopathology, functioning, quality of life, and service engagement were obtained for 27 cases of MDDP in comparison to 60 SZ, 27 SA, and 35 BD. RESULTS: Positive psychotic symptoms were less prominent in MDDP and BD than in SZ and SA. Negative symptoms, impaired functioning, and reduction in objectively determined quality of life were less prominent in MDDP and BD, intermediate in SA and most prominent in SZ. However, subjectively determined quality of life was indistinguishable across diagnoses. Service engagement was highest for MDDP, intermediate for SA and BD, and lowest for SZ. CONCLUSIONS: At 6-year follow-up, these diagnoses are characterized by quantitative rather than qualitative differences in psychopathology, functionality, quality of life, and service engagement, with considerable overlap between them. These findings suggest that MDDP should join SZ, SA, and BD in a milieu of psychosis that transcends arbitrary boundaries.

PMID- 29575684 TI - New mutations and an updated database for the patched-1 (PTCH1) gene. AB - BACKGROUND: Basal cell nevus syndrome (BCNS) is an autosomal dominant disorder characterized by multiple basal cell carcinomas (BCCs), maxillary keratocysts, and cerebral calcifications. BCNS most commonly is caused by a germline mutation in the patched-1 (PTCH1) gene. PTCH1 mutations are also described in patients with holoprosencephaly. METHODS: We have established a locus-specific database for the PTCH1 gene using the Leiden Open Variation Database (LOVD). We included 117 new PTCH1 variations, in addition to 331 previously published unique PTCH1 mutations. These new mutations were found in 141 patients who had a positive PTCH1 mutation analysis in either the VU University Medical Centre (VUMC) or Maastricht University Medical Centre (MUMC) between 1995 and 2015. RESULTS: The database contains 331 previously published unique PTCH1 mutations and 117 new PTCH1 variations. CONCLUSION: We have established a locus-specific database for the PTCH1 gene using the Leiden Open Variation Database (LOVD). The database provides an open collection for both clinicians and researchers and is accessible online at http://www.lovd.nl/PTCH1. PMID- 29575685 TI - High sensitivity and negative predictive value of sentinel lymph node biopsy in a retrospective early stage oral cavity cancer cohort in the Northern Netherlands. AB - OBJECTIVES: In cT1-2N0, oral squamous cell carcinoma (OSCC) occult metastases are detected in 23%-37% of cases. Sentinel lymph node biopsy (SLNB) was introduced in head and neck cancer as a minimally invasive alternative for an elective neck dissection in neck staging. Meta-analyses of SLNB accuracy show heterogeneity in the existing studies for reference standards, imaging techniques and pathological examination. The aim of this study was to assess the sensitivity and negative predictive value (NPV) of the SLNB in detecting occult metastases in cT1-2N0 OSCC in a well-defined cohort. DESIGN: Retrospective study. The SLNB procedure consisted of lymphoscintigraphy, SPECT/CT-scanning and gamma probe detection. Routine follow-up was the reference standard for the SLNB negative neck. Histopathological examination of sentinel lymph nodes (SLN) consisted of step serial sectioning, haematoxylin-eosin and cytokeratin AE1/3 staining. SETTING: Two comprehensive oncology centres. PARTICIPANTS: A total of 91 consecutive patients with primary cT1-2N0 OSCC treated by primary resection and neck staging by SLNB procedure between 2008 and 2016. MAIN OUTCOME MEASURES: Sensitivity and negative predictive value. RESULTS: In all cases, SLNs were harvested. A total of 25 (27%) patients had tumour-positive SLNs. The median follow-up was 32 months (range 2-104). Four patients were diagnosed with an isolated regional recurrence in the SLNB negative neck side resulting in an 85% sensitivity and a 94% NPV. CONCLUSION: In our cohort, the SLNB detected occult metastases in early OSCC with 85% sensitivity and 94% NPV. This supports that SLNB is a reliable procedure for surgical staging of the neck in case of oral cT1-2N0 SCC. PMID- 29575686 TI - Photoinduced Copper-Catalyzed Coupling of Terminal Alkynes and Alkyl Iodides. AB - We have developed a photoinduced copper-catalyzed alkylation of terminal alkynes with primary, secondary, or tertiary alkyl iodides as electrophiles. The reaction has a broad substrate scope and can be successfully performed in the presence of ester, nitrile, aryl halide, ketone, sulfonamide, epoxide, alcohol, and amide functional groups. The alkylation is promoted by blue light (lambda~450 nm) and proceeds at room temperature in the absence of any additional metal catalysts. The use of a terpyridine ligand is essential for the success of the reaction and is shown to prevent photoinduced copper-catalyzed polymerization of the starting materials. PMID- 29575687 TI - An outbreak of Getah virus infection among pigs in China, 2017. AB - A Getah virus (GETV) outbreak occurred in a swine farm in Hunan, China, between June and July 2017. Approximately 200 piglets died 5-10 days after birth, and more than 150 pregnant sows had stillbirths or foetal mummies in this outbreak. GETV HuN1, isolated from the cerebrum of an infected piglet, shared a close evolutionary relationship with the Kochi/01/2005 strain, isolated from pigs in Japan. GETV was detected in the cerebral cortices of a dead foetus and in various organs of two infected piglets, thereby demonstrating that GETV can be transmitted through the placenta to infected newborn piglets with multiple tissue tropisms. Seroepizootiologic investigation of GETV revealed that a wide infection of GETV had been persisting in the farm between June 1 and July 17. In conclusion, clinical and laboratory diagnostics of the diseased pigs in this outbreak were consistent with GETV being the causative agent. To the best of our knowledge, this is the first unequivocal report of GETV in pigs in China. PMID- 29575688 TI - Piriformospora indica inoculation alleviates the adverse effect of NaCl stress on growth, gas exchange and chlorophyll fluorescence in tomato (Solanum lycopersicum L.). AB - Salinity is now an increasingly serious environmental issue that affects the growth and yield of many plants. In the present work, the influence of inoculation with the symbiotic fungus, Piriformospora indica, on gas exchange, water potential, osmolyte content, Na/K ratio and chlorophyll fluorescence of tomato plants under three salinity levels (0, 50, 100 and 150 mm NaCl) and three time periods (5, 10 and 15 days after exposure to salt) was investigated. Results indicate that P. indica inoculation improved growth parameters of tomato under salinity stress. This symbiotic fungus significantly increased photosynthetic pigment content under salinity, and more proline and glycine betaine accumulated in inoculated roots than in non-inoculated roots. P. indica further significantly improved K+ content and reduced Na+ level under salinity treatment. After inoculation with the endophytic fungus, leaf physiological parameters, such as water potential, net photosynthesis, stomatal conductance and transpiration, were all higher under the salt concentrations and durations compared with controls without P. indica. With increasing salt level and salt treatment duration, values of F0 and qP increased but Fm , Fv /Fm , F'v /F'm and NPQ declined in the controls, while inoculation with P. indica improved these values. The results indicate that the negative effects of NaCl on tomato plants were alleviated after P. indica inoculation, probably by improving physiological parameters such as water status and photosynthesis. PMID- 29575689 TI - Tunable Confinement for Bridging Single-Cell Manipulation and Single-Molecule DNA Linearization. AB - DNA linearization by nanoconfinement has offered a new avenue toward large-scale genome mapping. The ability to smoothly interface the widely different length scales from cell manipulation to DNA linearization is critical to the development of single-cell genomic mapping or sequencing technologies. Conventional nanochannel technologies for DNA analysis suffer from complex fabrication procedures, DNA stacking at the nanochannel entrance, and inefficient solution exchange. In this work, a dynamic and tunable confinement strategy is developed to manipulate and linearize genomic-length DNA molecules from a single cell. By leveraging pneumatic microvalve control and elastomeric collapse, an array of nanochannels with confining dimension down to 20 nm and length up to sub millimeter is created and can be dynamically tuned in size. The curved edges of the microvalve form gradual transitions from microscale to nanoscale confinement, smoothly facilitating DNA entry into the nanochannels. A unified micro/nanofluidic device that integrates single-cell trapping and lysis, DNA extraction, purification, labeling, and linearization is developed based on dynamically controllable nanochannels. Mbp-long DNA molecules are extracted directly from a single cell and in situ linearized in the nanochannels. The device provides a facile and promising platform to achieve the ultimate goal of single-cell, single-genome analysis. PMID- 29575691 TI - Individual factors influencing the duration of untreated psychosis. AB - AIM: Duration of untreated psychosis (DUP), or the time between onset of psychosis and treatment initiation, is a prognostic factor of schizophrenia. However, few studies evaluated the relative influence of individual-related factors on this duration. The objective of this study was to evaluate the influence of socio-demographic, clinical and cannabis use on DUP. METHODS: This study was part of a large prospective study in help-seeking individuals referred to our specialized early detection / intervention clinic in the Service Hospitalo Universitaire of Sainte-Anne Hospital in Paris (ICAAR study). We explored 33 consecutive patients who crossed the CAARMS' threshold of psychosis. The DUP and cannabis consumption history were explored during the baseline comprehensive assessment using all available sources (direct interviews of patients, parents, practitioners). Correlations between socio-demographic, clinical and cannabis use, and DUP were studied. A multiple linear regression model was used to determine the variables that could significantly predict DUP. RESULTS: When considered individually, none of the socio-demographic and disease characteristic factors was associated with DUP, with the exception of level of education. In the multivariate analysis, age at inclusion, negative symptoms and history of cannabis use significantly influenced DUP. CONCLUSION: The determinants of DUP are multi-factorial and include individual centred factors, such as age, cannabis and negative symptoms. The identification of factors resulting in delayed access to care may promote the development of effective strategies to reduce DUP in early psychosis and target effective early intervention. PMID- 29575690 TI - Clarification of the Innervation of the Bladder, External Urethral Sphincter and Clitoris: A Neuronal Tracing Study in Female Mongrel Hound Dogs. AB - Many studies examining the innervation of genitourinary structures focus on either afferent or efferent inputs, or on only one structure of the system. We aimed to clarify innervation of the bladder, external urethral sphincter (EUS) and clitoris. Retrograde dyes were injected into each end organ in female dogs. Spinal cord, mid-bladder, and spinal, caudal mesenteric, sympathetic trunk and pelvic plexus ganglia were examined for retrograde dye-labeled neurons. Neurons retrogradely labeled from the bladder were found primarily in L7-S2 spinal ganglia, spinal cord lateral zona intermedia at S1-S3 levels, caudal mesenteric ganglia, T11-L2 and L6-S2 sympathetic trunk ganglia, and pelvic plexus ganglia. The mid-bladder wall contained many intramural ganglia neurons labeled anterogradely from the pelvic nerve, and intramural ganglia retrogradely labeled from dye labeling sites surrounding ureteral orifices. Neurons retrogradely labeled from the clitoris were found only in L7 and S1 spinal ganglia, L7-S3 spinal cord lateral zona intermedia, and S1 sympathetic trunk ganglia, and caudal mesenteric ganglia. Neurons retrogradely labeled from the EUS were found in primarily at S1 and S2 spinal ganglia, spinal cord lamina IX at S1-S3, caudal mesenteric ganglia, and S1-S2 sympathetic trunk ganglia. Thus, direct inputs from the spinal cord to each end organ were identified, as well as multisynaptic circuits involving several ganglia, including intramural ganglia in the bladder wall. Knowledge of this complex circuitry of afferent and efferent inputs to genitourinary structures is necessary to understand and treat genitourinary dysfunction. Anat Rec, 2018.

AB - Granulocyte colony-stimulating factor (G-CSF) has been widely used in the field of allogeneic haematopoietic stem cell transplantation (allo-HSCT) for priming donor stem cells from the bone marrow (BM) to peripheral blood (PB) to collect stem cells more conveniently. Donor-derived natural killer (NK) cells have important antitumour functions and immune regulatory roles post-allo-HSCT. The aim of this study was to evaluate the effect of G-CSF on donors' NK cells in BM and PB. The percentage of NK cells among nuclear cells and lymphocyte was significantly decreased and led to increased ratio of T and NK cells in BM and PB post-G-CSF in vivo application. Relative expansion of CD56bri NK cells led to a decreased ratio of CD56dim and CD56bri NK subsets in BM and PB post-G-CSF in vivo application. The expression of CD62L, CD54, CD94, NKP30 and CXCR4 on NK cells was significantly increased in PB after G-CSF treatment. G-CSF treatment decreased the IFN-gamma-secreting NK population (NK1) dramatically in BM and PB, but increased the IL-13-secreting NK (NK2), TGF-beta-secreting NK (NK3) and IL-10 secreting NK (NKr) populations significantly in BM. Clinical data demonstrated that higher doses of NK1 infused into the allograft correlated with an increased incidence of chronic graft-vs-host disease post-transplantation. Taken together, our results show that the in vivo application of G-CSF can modulate NK subpopulations, leading to an increased ratio of T and NK cells and decreased ratio of CD56dim and CD56bri NK cells as well as decreased NK1 populations in both PB and BM. PMID- 29575693 TI - Interaction of isolated cross-linked short actin oligomers with the skeletal muscle myosin motor domain. AB - The cyclical interaction between F-actin and myosin in muscle cells generates contractile force. The myosin motor domain hydrolyses ATP, resulting in conformational changes that are amplified by the myosin lever arm that links the motor domain to the rod domain. Recent cryo-electron microscopic data have provided a clear picture of the myosin-ATP-F-actin complex, but structural insights into other stages of the myosin-actin interaction have been less forthcoming. To address this issue, we cross-linked F-actin subunits between Cys374 and Lys191, and separated them by gel filtration. Purified actin-dimers, trimers and -tetramers retained the ability to polymerize and to stimulate myosin subfragment 1 (myosin-S1) ATPase activity. To generate stable actin oligomer:myosin-S1 complexes, we blocked actin polymerization with gelsolin and Clostridium botulinum iota toxin-mediated ADP-ribosylation. After polymerization inhibition, actin-trimers and -tetramers retained the ability to stimulate the myosin-S1-ATPase, whereas the actin-dimer showed very little ATPase stimulation. We then analysed the stoichiometry and binding affinity of myosin-S1 to actin oligomers. Actin-trimers and -tetramers bound myosin-S1 in the absence of nucleotide; the trimer contains one myosin-S1 binding site. We calculated a dissociation constant (Kd ) of 1.1 * 10-10 m and 1.9 * 10-10 m for binding of native F-actin and the actin-trimer to myosin-S1, respectively. EM of the actin trimer:myosin-S1 complex demonstrated the presence of single particles of uniform size. Image reconstruction allowed a reasonable fit of the actin-trimer and myosin-S1 into the obtained density clearly showing binding of one myosin-S1 molecule to the two long-pitch actins of the trimer, supporting the kinetic data.

AB - Various hydrogels made from natural or synthetic polymers have been widely used in biologic tissues, drug delivery, and artificial implants due to their good biocompatibility, indicating a promising perspective in regenerative medicine. In the present study, a composite hydrogel named polyacrylamide/graphene oxide/gelatin/sodium alginate (PAM/GO/Gel/SA) for accelerating peripheral nerve regeneration was fabricated through in situ free radical polymerization for the first time. A series of physicochemical properties including morphology, porosity, swelling behaviors, component, mechanical properties, and in vitro degradation behavior of the prepared composite hydrogel were characterized. The effects of the composite hydrogel on Schwann cells growth were evaluated and the related molecular mechanism was further penetrated. The results showed that the prepared PAM/GO/Gel/SA composite hydrogels displayed different color appearance as the function of component variations. The surface morphology, components, swelling ratio, mechanical properties, and porosity were all changed with the concentration alteration of each ingredient, while no obvious degradation behavior was observed, indicating a controllable physicochemical property. The culture of cells exhibited that the composite hydrogels could well support the attachment and proliferation of Schwann cells. The gene expression levels of Sox10, GAP43, and myelin basic protein (MBP) in PGG0.5 SYR1 and PGG1 SYR0.5 were higher than those of NC. This study may provide important theoretical and experimental basis for the design and development of hydrogel scaffolds for nerve tissue engineering application. (c) 2018 Wiley Periodicals, Inc.

AB - OBJECTIVE: Aging is a significant risk factor for the development of obesity and hepatic steatosis associated with insulin and leptin resistance. Food restriction (FR) is commonly used for reducing body weight (BW), adiposity, and liver steatosis. Thus, this study aimed to determine whether FR in middle-aged rats can recover the central leptin antisteatotic effects observed in the liver in young animals. METHODS: Two groups of 4-month-old Wistar rats were fed ad libitum (AL) or were on FR for 3 months. At 7 months of age, both groups were centrally treated with rat leptin (0.2 MUg/d, 7 days) or saline. RESULTS: Central leptin reduced food intake and BW, but not the hepatic triglyceride content, in 7-month old rats fed AL. However, in 7-month-old FR rats, leptin did not affect BW but markedly reduced serum leptin, serum and hepatic triglyceride levels, and the expression of hepatic lipogenic genes. In addition, central leptin decreased serum and hepatic endogenous norepinephrine levels of FR rats, exerting a homeostatic effect beyond its antisteatotic actions. CONCLUSIONS: These findings suggest that in middle-aged rats, moderate FR is required for both preserving the antisteatotic actions of central leptin and avoiding excessive weight loss. PMID- 29575697 TI - Fetal Development of Fasciae around the Arm and Thigh Muscles: A Study Using Late Stage Fetuses. AB - To obtain a better understanding of multi-laminar deep fascia covering skeletal muscles, we examined nondecalcified histological sections of the arm and thigh of 20 human fetuses aged 25-33 weeks. Morphologies of the fasciae varied between sites and specimens, but the initial morphology was most likely to be a thin and loose sheet on the external surface of the muscles (fascia-1 or F1). When the F1 became wavy, thick and tight, it was detached from the muscle surface. Beneath the F1, the second lamina of fascia (F2) appeared on the muscle surface and it was also detached. In this manner at 25-33 weeks' gestation, fasciae covering the triceps and vastus lateralis muscles had a three-layered configuration (F1, F2, and F3). Due to significant individual variations, this process was not correlated to the ages and sizes of specimens. Muscle contractions might facilitate the detachment. In these muscles, the intramuscular tendon joined the F2 or F3 and the latter became thick and aponeurotic. Along the finally developed lamina, muscle fibers carried a desmin-positive spot for insertion. Increased laminae were accompanied by a reduced number of CD68-positive macrophages and, nerves were absent, near the developing fascia. In contrast to skin ligaments or superficial fasciae showing de novo development in loose tissue, a deep or muscle covering fascia seemed to originate from the skeletal muscle itself at the surface, and this process was repeated to produce multi-layered fascia. Depending on sites, collagen fibers were added by the intramuscular tendon. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29575698 TI - Effects of Short-Term Normobaric Hypoxic Walking Training on Energetics and Mechanics of Gait in Adults with Obesity. AB - OBJECTIVE: The aim of this study was to compare the effects of short-term hypoxic versus normoxic training at preferred walking speed (PWS) on energetics, mechanics, efficiency, and metabolic risk markers in individuals with obesity. METHODS: Twenty-three subjects with obesity performed nine 1-hour sessions at PWS under hypoxia (3,000 m, n = 12; BMI: 34.0 +/- 0.8 kg/m2 ) or normoxia (360 m, n = 11; BMI: 32.9 +/- 0.8 kg/m2 ). Participants performed six 5-minute walking trials at different speeds (PWS, 0.56, 0.83, 1.11, 1.39, and 1.67 m/s). The net energy cost, external mechanical work, and rated perceived exertion (RPE) were measured at these speeds. Body composition and blood samples were collected. RESULTS: PWS tended to be slower under hypoxia than normoxia (-6.7%; P = 0.092) during the training, and this difference reached significance the third week (-8.9%; P = 0.05). After training, PWS significantly increased (+ 8.2%; P <= 0.001), while RPE decreased (P = 0.005). Ankle range of motion (P = 0.03) and vertical displacement of the center of mass (P = 0.02) significantly increased in both groups. CONCLUSIONS: A walking training program under hypoxia at slower PWS than in normoxia elicited similar responses in metabolic risk factors, energetics, and mechanics of walking in individuals with obesity. Both programs increased PWS, decreased RPE, and induced gait-pattern adaptations, which protected against orthopedic injury in these individuals. PMID- 29575699 TI - Natural Polyphenols Selectively Inhibit beta-Carbonic Anhydrase from the Dandruff Producing Fungus Malassezia globosa: Activity and Modeling Studies. AB - Around 50 % of the worldwide population is affected by dandruff, which is triggered by a variety of factors. The yeast Malassezia globosa has been labeled as the most probable causative agent for the onset of dandruff. The beta-carbonic anhydrase (CA) of MgCA was recently validated as an anti-dandruff target, with its inhibition being responsible for in vivo growth defects in the fungus. As classical CA inhibitors of the sulfonamide type give rise to permeability problems through biological membranes, finding non-sulfonamide alternatives for MgCA inhibition is of considerable interest in the cosmetic field. We recently screened a large library of human (h) CA inhibitors for MgCA inhibition, including different chemotypes, such as monothiocarbamates, dithiocarbamates, phenols, and benzoxaboroles. Herein, we expanded the research toward new MgCA inhibitors by considering a set of natural polyphenols (including flavones, flavonols, flavanones, flavanols, isoflavones, and depsides) that exhibited MgCA inhibitory activity in the micromolar range, as well as selectivity for the fungal isozyme over off-target human isoforms. The binding mode of representative derivatives within the MgCA catalytic cleft was investigated by docking studies using a homology-built model. PMID- 29575700 TI - Antimicrobial-resistant Enterobacteriaceae recovered from companion animal and livestock environments. AB - Antimicrobial-resistant bacteria represent an important concern impacting both veterinary medicine and public health. The rising prevalence of extended-spectrum beta-lactamase (ESBL), AmpC beta-lactamase, carbapenemase (CRE) and fluoroquinolone-resistant Enterobacteriaceae continually decreases the efficiency of clinically important antibiotics. Moreover, the potential for zoonotic transmission of antibiotic-resistant enteric bacteria increases the risk to public health. Our objective was to estimate the prevalence of specific antibiotic-resistant bacteria on human contact surfaces in various animal environments. Environmental surface samples were collected from companion animal shelters, private equine facilities, dairy farms, livestock auction markets and livestock areas of county fairs using electrostatic cloths. Samples were screened for Enterobacteriaceae expressing AmpC, ESBL, CRE or fluoroquinolone resistance using selective media. Livestock auction markets and county fairs had higher levels of bacteria expressing both cephalosporin and fluoroquinolone resistance than did equine, dairy, and companion animal environments. Equine facilities harboured more bacteria expressing cephalosporin resistance than companion animal shelters, but less fluoroquinolone resistance. The regular use of extended spectrum cephalosporins in livestock populations could account for the increased levels of cephalosporin resistance in livestock environments compared to companion animal and equine facilities. Human surfaces, as well as shared human and animal surfaces, were contaminated with resistant bacteria regardless of species environment. Detecting these bacteria on common human contact surfaces suggests that the environment can serve as a reservoir for the zoonotic transmission of antibiotic-resistant bacteria and resistance genes. Identifying interventions to lower the prevalence of antibiotic-resistant bacteria in animal environments will protect both animal and public health.

AB - Silver staining, which exploits the special bioaffinity and the chromogenic reduction of silver ions, is an indispensable visualization method in biology. It is a most popular method for in-gel protein detection. However, it is limited by run-to-run variability, background staining, inability for protein quantification, and limited compatibility with mass spectroscopic (MS) analysis; limitations that are largely attributed to the tricky chromogenic visualization. Herein, we reported a novel water-soluble fluorogenic Ag+ probe, the sensing mechanism of which is based on an aggregation-induced emission (AIE) process driven by tetrazolate-Ag+ interactions. The fluorogenic sensing can substitute the chromogenic reaction, leading to a new fluorescence silver staining method.

AB - An asymmetric aza-Friedel-Crafts alkylation reaction between indoles and indolenines that were derived in situ from 3-indolinone-2-carboxylates has been developed by using 3,3'-bis(triphenylsilyl)-1,1'-binaphthyl-2,2'-diyl hydrogen phosphate as a catalyst. The reaction proceeded under mild conditions and provided chiral indol-3-yl-3-indolinone-2-carboxylate derivatives in good yields with excellent ee values (up to 98.6 %). Similarly, the Mannich-type addition of indoline-3-ones to indolenines provided heterodimers with vicinal chiral quaternary centers. This method was successfully applied to the construction of the core structure of trigonoliimine C.

AB - Rpd3 is a class I histone deacetylase that reverses lysine acetylation thus influencing cellular processes and functions. However, its role in fungal insect pathogens has not been explored yet. Here we show that Rpd3-dependent lysine modification and gene expression orchestrate growth, conidiation and virulence in Beauveria bassiana. Deletion of Rpd3 resulted in severe growth defects on various carbon/nitrogen sources, 97% reduction in conidiation capacity and drastic attenuation in virulence. These phenotypes concurred with differential expression of 1479 proteins and hyperacetylation or hypoacetylation of 2227 lysine residues on 1134 proteins. Many of these proteins fell into carbon/nitrogen metabolism and cell rescue/defence/virulence, indicating vital roles of Rpd3-dependent protein expression and lysine modification in the fungal growth and virulence. Intriguingly, lysine residues of four core histones (H2A, H2B, H3 and H4) and many histone acetyltransferases were also hyper- or hypoacetylated in Deltarpd3, suggesting direct and indirect roles for Rpd3 in genome-wide lysine modification. However, crucial development activators were transcriptionally repressed and not found in either proteome or acetylome. Single/double-site-directed H3K9/K14 mutations for hyper/hypoacetylation exerted significant impacts on conidiation and dimorphic transition crucial for fungal virulence. Altogether, Rpd3 mediates growth, asexual development and virulence through transcriptional/translational regulation and posttranslational lysine modification in B. bassiana.

AB - A facile access to optically active cyclic ureas was developed through palladium catalyzed asymmetric hydrogenation of pyrimidines containing tautomeric hydroxy group with up to 99 % ee. Mechanistic studies indicated that reaction pathway proceed through hydrogenation of C=N of the oxo tautomer pyrimidin-2(1H)-one, acid-catalyzed isomerization of enamine-imine, and hydrogenation of imine pathway. In addition, the chiral cyclic ureas are readily converted into useful chiral 1,3-diamine and thiourea derivatives without loss of optical purity.

AB - Organic-inorganic lead halide perovskite phases segregate (and their structures degrade) under illumination, exhibiting a poor stability with hysteresis and producing halide accumulation at the surface.In this work, we observed structural and interfacial dissociation in methylammonium lead iodide (CH3 NH3 PbI3 ) perovskites even under dark and vacuum conditions. Here, we investigate the origin and consequences of self-degradation in CH3 NH3 PbI3 perovskites stored in the dark under vacuum. Diffraction and photoelectron spectroscopic studies reveal the structural dissociation of perovskites into PbI2 , which further dissociates into metallic lead (Pb0 ) and I2- ions, collectively degrading the perovskite stability. Using TOF-SIMS analysis, AuI2- formation was directly observed, and it was found that an interplay between CH3 NH3+ , I3- , and mobile I- ions continuously regenerates more I2- ions, which diffuse to the surface even in the absence of light. Besides, halide diffusion causes a concentration gradient between Pb0 and I2- and creates other ionic traps (PbI2- , PbI- ) that segregate as clusters at the perovskite/gold interface. A shift of the onset of the absorption band edge towards shorter wavelengths was also observed by absorption spectroscopy, indicating the formation of defect species upon aging in the dark under vacuum. PMID- 29575707 TI - Predictors of student use of an electronic record. AB - BACKGROUND: Little is known on ambulatory clerkship students' use of an electronic medical record (EMR). We investigated students' use of recommended EMR tasks across different types of sites and studied the predictors of these recommended tasks. METHODS: Students documented how often they performed recommended EMR tasks and suggested improvements to enhance EMR use. We compared student performance of recommended tasks across different types of sites using chi2 tests and the Fisher's exact test. We performed regression analyses to investigate factors predicting students' performance of EMR tasks. Two faculty members read all of the suggested improvements and agreed on themes. RESULTS: From January 2014 to June 2015, 263 of 295 Family and Community Medicine Clerkship (FCMC) students (89.2%) were at sites that used an EMR. Of the 263 students, 68.4% typed their own note into the EMR, but only 31.2% entered orders and 27.8% entered prescriptions for their teacher to sign. Students' rating of the orientation to the EMR predicted their use of all EMR tasks. The number of years that the teaching site used an EMR predicted the students' use of some tasks. Suggested improvements included a better orientation to the EMR, more use of the EMR, and access to a computer and the EMR. Little is known on ambulatory clerkship students' use of an electronic medical record DISCUSSION: Many students did not perform recommended EMR tasks. To help more students learn EMR tasks, clinical teachers can offer students a detailed orientation to their EMR, provide them with access to a computer and the EMR, and give them the opportunity to perform recommended EMR tasks, including typing their own note and entering orders and prescriptions. PMID- 29575708 TI - The impact of aerobic exercise training with vascular occlusion in patients with chronic heart failure. AB - AIMS: This study aimed to evaluate the impact of aerobic exercise training with vascular occlusion in patients with chronic heart failure. METHODS AND RESULTS: Thirty patients with post-infarction heart failure were randomized to an interventional exercise group (IG; n = 15) or a control exercise group (CG; n = 15). Exercise was performed at an intensity of 40-70% of the peak VO2 /W for 6 months. Patients in the IG remained seated on the saddle of the cycle ergometer with their feet on the pedals. Pneumatic tourniquets were applied to the proximal ends of their thighs with appropriate pressure resulting in a 40-80 mmHg increase in the systolic blood pressure that is required for vascular occlusion (208.7 +/- 7.4 mmHg). We evaluated the safety and efficacy of the intervention and its effect on exercise capacity and serum BNP levels. There were no significant differences between the IG and CG in patient characteristics at study entry. Peak VO2 /W in the IG significantly increased compared with that in the CG; the change in the serum BNP levels was significantly larger in the IG than in the CG. CONCLUSIONS: These results suggest that aerobic exercise training with vascular occlusion can improve exercise capacity and serum BNP levels in patients with chronic heart failure.

AB - The search for nonprecious-metal-based catalysts for the synthesis of gamma valerolactone (GVL) through hydrogenation of levulinic acid and its derivatives in an efficient fashion is of great interest and importance, as GVL is an important a sustainable liquid. We herein report a pincer iron complex that can efficiently catalyze the hydrogenation of levulinic acid and methyl levulinate into GVL, achieving a turnover number of up to 23 000 and a turnover frequency of 1917 h-1 . This iron-based catalyst also enabled the formation of GVL from various biomass-derived carbohydrates in aqueous solution, thus paving a new way toward a renewable chemical industry. PMID- 29575710 TI - Divergently Seeking Clarification: The Emergence of Clarification Interaction. AB - Clarification requests, queries posed in response to a "problematic" (misheard, misunderstood, etc.) utterance, are a challenge to mainstream semantic theories because they call into question notions such as "shared content" or "the context." Given their strong parallelism requirements, elliptical clarification requests introduce in addition significant complexities concerning the need for long-term maintenance of non-semantic information in context. In this paper, we consider a puzzle concerning the emergence of elliptical clarification requests in child English: Data from the Belfast and Manchester corpora from CHILDES demonstrate that reprise fragments, the highest frequency clarification request construction among adults, emerges with significant delay in comparison with reprise sluices, bare wh-phrases used to request clarification. This is a puzzling finding a priori: first, since reprise fragments are by most plausible measures the most readily available clarification request form in that it involves mere repetition of material primed by the previous utterance and children have the ability to repeat parts of the previous utterance from the earliest stages of speech. Moreover, as we show, reprise fragments predominate-in some cases vastly so, over sluicing in the input of fragmentary clarification requests available to the child-and it would, therefore, be difficult to construct an explanation for order of emergence primarily based on frequency of the construction in the children's input. Our account is based on grammatical explication of the difference between the constructions, how constructional difference is represented in a hierarchy of constructions, and in terms of a notion of semantic complexity that suggests reprise sluicing is, in fact, less complex than reprise fragments.

AB - OBJECTIVE: Hearing loss subsequent to a unilateral vestibular schwannoma (VS) has an impact on the social life of non-operated patients. We investigated the utility of auditory brainstem responses (ABRs) for predicting the results of auditory rehabilitation in such patients. DESIGN: Prospective study. SETTING: University tertiary medical centre. PARTICIPANTS: We collected the demographic, audiometric, ABR and imaging data of non-operated patients with unilateral VS. A hearing aid trial was performed over 1 month. We assessed auditory performance following the auditory rehabilitation according to the ABR results. Patients with distinct waves (I, III and V) were included in the "distinct ABR" group and patients with no ABR were included in the "desynchronised ABR" group. MAIN OUTCOME MEASURES: Following the trial, audiometric performance and quality of life were evaluated with the Glasgow Benefit Inventory (GBI). SUBJECTS AND METHOD: We collected the demographic, audiometric, ABR and imaging data of non operated patients with unilateral VS. A hearing aid trial was performed over 1 month. Following the trial, audiometric performance and quality of life were evaluated with the Glasgow Benefit Inventory (GBI). We assessed auditory performance following the auditory rehabilitation according to the ABR results. Patients with distinct waves (I, III and V) were included in the "distinct ABR" group and patients with no ABR were included in the "desynchronised ABR" group. RESULTS: In total, 25 patients were included in this prospective study; 15 in the "distinct ABR" group and 10 in the "desynchronised ABR" group. The speech recognition threshold (SRT, P < .0001; W = -120) and speech discrimination score (P = .0005; W = 78) were significantly improved in the aided vs unaided conditions. These improvements were not observed in the "desynchronised ABR" group for the SRT (P = .48; W = -10) and word recognition score (P = .06; W = 15). Ninety-three per cent of the patients in the "distinct ABR" group kept significantly (P = .04) the hearing aids following the trial compared to 20% in the "desynchronised ABR" group. CONCLUSIONS: Auditory brainstem responses can help to predict the auditory performance following auditory rehabilitation in unilateral non-operated VS patients. PMID- 29575712 TI - Structure Elucidation of the Main Tetrahydroxyxanthones of Hypericum Seeds and Investigations into the Testa Structure. AB - Seeds from Hypericum species have recently been identified as an interesting source of xanthone derivatives. Extraction of seeds from H. perforatum with MeOH and subsequent concentration via polyamide adsorption yielded a fraction enriched in tetrahydroxyxanthones (THX), which were further semipurified by silica gel chromatography. Based on tentative structure assignment of the two main THX X1 and X2 by NMR a total synthesis was performed for both compounds (THX 1 and 2, respectively), starting with an Ullmann ether synthesis. The synthesized 1 and 2 were characterized via 1D- and 2D-NMR methods as well as by LC/HR-MS analysis and proven to be 1,4,6,7-THX (1) and 1,2,6,7-THX (2). Final structure assignment of the natural Hypericum THX constituents was accomplished by comparing chromatographic and spectroscopic data (LC/MSn and GC/MS) with those of 1 and 2 which were obtained by synthesis. Beyond, investigations into the seeds of H. perforatum and H. tetrapterum by scanning electron microscopy (SEM) provided insights of the structure of the testa (seed coat), which is established by two cell layers, with the lignified sclerenchyma presumably being the depository of the xanthones.

PMID- 29575713 TI - Functional transcriptomic annotation and protein-protein interaction analysis identify EZH2 and UBE2C as key upregulated proteins in ovarian cancer. AB - Although early stage ovarian cancer is in most cases a curable disease, some patients relapse even with appropriate adjuvant treatment. Therefore, the identification of patient and tumor characteristics to better stratify risk and guide rational drug development is desirable. Using transcriptomic functional annotation followed by protein-protein interacting (PPI) network analyses, we identified functions that were upregulated and associated with detrimental outcome in patients with early stage ovarian cancer. Some of the identified functions included cell cycle, cell division, signal transduction/protein modification, cellular response to extracellular stimuli or transcription regulation, among others. Genes within these functions included AURKA, AURKB, CDK1, BIRC5, or CHEK1 among others. Of note, the histone-lysine N methyltransferase (EZH2) and the ubiquitin-conjugating enzyme E2C (UBE2C) genes were found to be upregulated and amplified in 10% and 6% of tumors, respectively. Of note, EZH2 and UBE2C were identified as principal interacting proteins of druggable networks. In conclusion, we describe a set of genes overexpressed in ovarian cancer with potential for therapeutic intervention including EZH2 and UBE2C. PMID- 29575716 TI - Standardization of extracellular vesicle measurements by flow cytometry through vesicle diameter approximation. AB - : Essentials Platelet extracellular vesicles (EVs) concentrations measured by flow cytometers are incomparable. A model is applied to convert ambiguous scatter units to EV diameter in nanometer. Most included flow cytometers lack the sensitivity to detect EVs of 600 nm and smaller. The model outperforms polystyrene beads for comparability of platelet EV concentrations. SUMMARY: Background Detection of extracellular vesicles (EVs) by flow cytometry has poor interlaboratory comparability, owing to differences in flow cytometer (FCM) sensitivity. Previous workshops distributed polystyrene beads to set a scatter based diameter gate in order to improve the comparability of EV concentration measurements. However, polystyrene beads provide limited insights into the diameter of detected EVs. Objectives To evaluate gates based on the estimated diameter of EVs instead of beads. Methods A calibration bead mixture and platelet EV samples were distributed to 33 participants. Beads and a light scattering model were used to set EV diameter gates in order to measure the concentration of CD61-phycoerythrin-positive platelet EVs. Results Of the 46 evaluated FCMs, 21 FCMs detected the 600-1200-nm EV diameter gate. The 1200-3000-nm EV diameter gate was detected by 31 FCMs, with a measured EV concentration interlaboratory variability of 81% as compared with 139% with the bead diameter gate. Part of the variation in both approaches is caused by precipitation in some of the provided platelet EV samples. Flow rate calibration proved essential because systems configured to 60 MUL min-1 differed six-fold in measured flow rates between instruments. Conclusions EV diameter gates improve the interlaboratory variability as compared with previous approaches. Of the evaluated FCMs, 24% could not detect 400-nm polystyrene beads, and such instruments have limited utility for EV research. Finally, considerable differences were observed in sensitivity between optically similar instruments, indicating that maintenance and training affect the sensitivity. PMID- 29575717 TI - Benefits of antifungal therapy in asthma patients with airway mycosis: A retrospective cohort analysis. AB - INTRODUCTION: Fungal airway infection (airway mycosis) is increasingly recognized as a cause of asthma and related disorders. However, prior controlled studies of patients treated with antifungal antibiotics have produced conflicting results. Our objective is to measure the effect of antifungal therapy in moderate to severe adult asthmatics with positive fungal sputum cultures in a single center referral-based academic practice. METHODS: We retrospectively evaluated 41 patients with asthma and culture-proven airway mycosis treated with either terbinafine, fluconazole, itraconazole, voriconazole, or posaconazole for 4 to >12 weeks together with standard bronchodilator and anti-inflammatory agents. Asthma control (1 = very poorly controlled; 2 = not well controlled; and 3 = well controlled), peak expiratory flow rates (PEFR), serum total IgE, and absolute blood eosinophil counts before and after antifungal therapy were assessed. In comparison, we also studied nine patients with airway mycosis and moderate to severe asthma who received standard therapy but no antifungals. RESULTS: Treatment with azole-based and allylamine antifungals was associated with improved asthma control (mean change in asthma control 1.72-2.25; p = 0.004), increased PEFR (69.4% predicted to 79.3% predicted, p = 0.0011) and markedly reduced serum IgE levels (1,075 kU/L to 463 kU/L, p = 0.0005) and blood eosinophil counts (Mean absolute count 530-275, p = 0.0095). Reduction in symptoms, medication use, and relapse rates decreased as duration of therapy increased. Asthmatics on standard therapy who did not receive antifungals showed no improvement in asthma symptoms or PEFR. Antifungals were usually well tolerated, but discontinuation (12.2%) and relapse (50%) rates were relatively high. CONCLUSION: Antifungals help control symptoms in a subset of asthmatics with culture-proven airway mycosis. Additional randomized clinical trials are warranted to extend and validate these findings. PMID- 29575719 TI - Significance and indications for reoperative portoenterostomy in biliary atresia in light of long-term outcome. AB - BACKGROUND: Among biliary atresia (BA) patients undergoing revision following failed portoenterostomy, long-term native liver survival (NLS), physical condition, and indications for revision were explored. METHODS: From 1977-2015, 33 of 95 BA patients (35%) at our institution underwent revision. Ten- and 20 year NLS rates (NLSRs) and biochemical statuses of 20-year-old native liver survivors were compared between post-portoenterostomy BA patients with and without history of revision. Factors associated with 10-year NLS following revision and optimal cut-offs for potential predictors were analyzed. RESULTS: Overall 10- and 20-year NLSRs were 57% and 54%, respectively. Ten- and 20-year NLSRs were 49% and 45% in the revision group and 63% and 61% in the non-revision group, respectively. Among 20-year-old native liver survivors, differences in admission rates between ages 10-20 years were not significant for cholangitis (revision, 46%; non-revision, 40%; P = 0.30) or portal hypertension (revision, 38%; non-revision, 15%; P = 0.21). Differences in hepatobiliary function associated blood tests between these groups at 20 years old were only significant for aspartate aminotransferase (P = 0.02) and gamma-glutamyl transpeptidase (P = 0.047). Among potential predictors of 10-year NLS that we investigated, rate of change in total bilirubin (TB) over the first month post-portoenterostomy was best (P = 0.0019), and the receiver operating characteristic curve revealed an optimal cut-off for this first-month change in TB of -3.7 mg/dl (area under the curve, 0.85; sensitivity, 0.79; specificity, 0.83). CONCLUSIONS: In approximately half of the patients, revision provided 10- and 20-year NLS, and biochemical status at 20 years old was comparable across revision and non-revision patients. Rate of change in TB during the first month post-portoenterostomy offers a sensitive predictor of revision. PMID- 29575718 TI - Germline MLH1, MSH2 and MSH6 variants in Brazilian patients with colorectal cancer and clinical features suggestive of Lynch Syndrome. AB - Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by germline mutations in one of the major genes involved in mismatch repair (MMR): MLH1, MSH2, MSH6 and more rarely, PMS2. Recently, germline deletions in EPCAM have been also associated to the syndrome. Most of the pathogenic MMR mutations found in LS families occur in MLH1 or MSH2. Gene variants include missense, nonsense, frameshift mutations, large genomic rearrangements and splice-site variants and most of the studies reporting the molecular characterization of LS families have been conducted outside South America. In this study, we analyzed 60 unrelated probands diagnosed with colorectal cancer and LS criteria. Testing for germline mutations and/or rearrangements in the most commonly affected MMR genes (MLH1, MSH2, EPCAM and MSH6) was done by Sanger sequencing and MLPA. Pathogenic or likely pathogenic variants were identified in MLH1 or MSH2 in 21 probands (35.0%). Of these, approximately one-third were gene rearrangements. In addition, nine variants of uncertain significance (VUS) were identified in 10 (16.6%) of the sixty probands analyzed. Other four novel variants were identified, only in MLH1. Our results suggest that MSH6 pathogenic variants are not common among Brazilian LS probands diagnosed with CRC and that MMR gene rearrangements account for a significant proportion of the germline variants in this population underscoring the need to include rearrangement analysis in the molecular testing of Brazilian individuals with suspected Lynch syndrome. PMID- 29575720 TI - Polydopamine Particle-Filled Shape-Memory Polyurethane Composites with Fast Near Infrared Light Responsibility. AB - A new kind of fast near-infrared (NIR) light-responsive shape-memory polymer composites was prepared by introducing polydopamine particles (PDAPs) into commercial shape-memory polyurethane (SMPU). The toughness and strength of the polydopamine-particle-filled polyurethane composites (SMPU-PDAPs) were significantly enhanced with the addition of PDAPs due to the strong interface interaction between PDAPs and polyurethane segments. Owing to the outstanding photothermal effect of PDAPs, the composites exhibit a rapid light-responsive shape-memory process in 60 s with a PDAPs content of 0.01 wt%. Due to the excellent dispersion and convenient preparation method, PDAPs have great potential to be used as high-efficiency and environmentally friendly fillers to obtain novel photoactive functional polymer composites. PMID- 29575721 TI - Synthesis, Pharmacological Evaluation, and Docking Studies of Novel Pyridazinone Based Cannabinoid Receptor Type 2 Ligands. AB - In recent years, cannabinoid type 2 receptors (CB2 R) have emerged as promising therapeutic targets in a wide variety of diseases. Selective ligands of CB2 R are devoid of the psychoactive effects typically observed for CB1 R ligands. Based on our recent studies on a class of pyridazinone 4-carboxamides, further structural modifications of the pyridazinone core were made to better investigate the structure-activity relationships for this promising scaffold with the aim to develop potent CB2 R ligands. In binding assays, two of the new synthesized compounds [6-(3,4-dichlorophenyl)-2-(4-fluorobenzyl)-cis-N-(4-methylcyclohexyl)-3 oxo-2,3-dihydropyridazine-4-carboxamide (2) and 6-(4-chloro-3-methylphenyl)-cis-N (4-methylcyclohexyl)-3-oxo-2-pentyl-2,3-dihydropyridazine-4-carboxamide (22)] showed high CB2 R affinity, with Ki values of 2.1 and 1.6 nm, respectively. In addition, functional assays of these compounds and other new active related derivatives revealed their pharmacological profiles as CB2 R inverse agonists. Compound 22 displayed the highest CB2 R selectivity and potency, presenting a favorable in silico pharmacokinetic profile. Furthermore, a molecular modeling study revealed how 22 produces inverse agonism through blocking the movement of the toggle-switch residue, W6.48. PMID- 29575722 TI - Differential effects of transient and sustained activation of BDNF-TrkB signaling. AB - Brain-derived neurotrophic factor (BDNF) serves a pleiotropic role in the central nervous system, ranging from promoting neuronal survival and differentiation during development and synaptic modulation in the adult. An important, yet unanswered question is how BDNF could serve such diverse functions, sometimes in the same cell. At least two modes of BDNF actions have been elucidated so far based on BDNF signaling kinetics and/or the activity status of the responding neurons. Acute and gradual increases in extracellular BDNF concentrations elicit, respectively, transient and sustained activation of TrkB receptor and its downstream signaling, leading to differential molecular and cellular functions. In cultured neurons, sustained TrkB activation promotes neuronal dendritic arborization and spinogenesis, whereas transient TrkB activation facilitates dendritic growth and spine morphogenesis. In hippocampal slices, slow delivery of BDNF facilitates LTP, whereas fast application of BDNF enhances basal synaptic transmission in schaffer collateral synapses. High-frequency stimulation of neurons converts BDNF-induced TrkB signaling from a transient to a sustained mode. These initial insights lay the foundation for future investigation of the BDNF-TrkB pathway, and analogous signaling pathways to gain a comprehensive understanding to enable translational research.

AB - Bimetallic ion exchange on a zeolite often impacts its catalytic properties compared to its monometallic counterparts. Here, we address the synergistic effect of simultaneous copper and zinc ion exchange on mordenite (MOR), as found earlier for dimethyl ether (DME) carbonylation. Samples with various Cu/Zn ratios were characterized by diffuse-reflectance infrared Fourier-transform spectroscopy (DRIFTS) in the 3600 and 720 cm-1 regions, pore distribution analysis through Ar physisorption, X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), and transmission electron microscopy (TEM). When ion-exchanged alone, copper preferentially occupies 12-membered rings, whereas zinc occupies 8 membered rings. In bimetallic combinations, the zinc addition was found to prevent the copper from sintering into nanoparticles and to increase its coordination strength to the zeolite. At a Cu/Zn ratio of 0.25 (for MOR with Si/Al=6.5), copper promotes zinc ion exchange into 12-membered rings, more specifically, into T4 sites that are known for the formation of the coke precursor in DME carbonylation on a MOR. The sites became blocked during the bimetallic ion exchange, leading to suppressed catalyst deactivation. The study contributes to the understanding of mutual ion effects in bimetallic exchanged zeolites and highlights the major role of copper as a governing factor in determining the location of co-exchanged zinc on a MOR.

AB - Molecular structures for three oxidation forms (anion, radical, and cation) of terbium(III) bis(porphyrinato) double-decker complexes have been systematically studied. We found that the redox state controls the azimuthal rotation angle (phi) between the two porphyrin macrocycles. For [TbIII (tpp)2 ]n (tpp: tetraphenylporphyrinato, n=-1, 0, and +1), phi decreases at each stage of the oxidation process. The decrease in phi is due to the higher steric repulsion between the phenyl rings on the porphyrin macrocycle and the beta hydrogen atoms on the other porphyrin macrocycle, which results from the shorter interfacial distance between the two porphyrin macrocycles. Conversely, phi=45 degrees for both [TbIII (oep)2 ]-1 and [TbIII (oep)2 ]0 (oep: octaethylporphyrinato), but phi=36 degrees for [TbIII (oep)2 ]+1 . Theoretical calculations suggest that the smaller azimuthal rotation angle of the cation form is due to the electronic interaction in the doubly oxidized ligand system. PMID- 29575724 TI - Cross-sectional survey of biosimilar insulin utilization in Asia: The Joint Asia Diabetes Evaluation Program. AB - AIMS/INTRODUCTION: Biosimilar insulin can reduce treatment costs, although the extent of its use is largely unknown. We examined biosimilar insulin use and its associations with the quality of glycemic control using the Joint Asia Diabetes Evaluation register. MATERIALS AND METHODS: We carried out a cross-sectional analysis in 81,531 patients with type 1 and type 2 diabetes enrolled into the Joint Asia Diabetes Evaluation Program from 2007 to 2014. All insulin related terms are extracted from the Joint Asia Diabetes Evaluation portal, and compared clinical profiles between biosimilar and originator insulin users. Multivariate analysis was performed to assess the association of biosimilar insulin compared with originator insulin with dosage, glycated hemoglobin and hypoglycemia events. RESULTS: Amongst 81,531 patients, 20.5% (n = 16,738) were insulin-treated. In four countries with high use of biosimilar insulin, 4.7% (n = 719) of insulin users (n = 10,197) were treated with biosimilar insulin (India n = 507, 70.3%; the Philippines n = 90, 12.5%; China n = 62, 8.6%; Vietnam n = 60, 8.3%). Biosimilar insulin users were younger and had higher body mass index, glycated hemoglobin, insulin dosage and more frequent hypoglycemia than originator insulin users. These associations were non-significant after adjustment for confounders. Only age, college education, diabetes education, lipid control, physical activity and history of cardiovascular complications were independently associated with these quality measures. CONCLUSIONS: Biosimilar insulin use is not uncommon in Asia. Data exclusion due to incomplete capturing of brand names suggests possibly higher use. The multiple determinants of the quality of glycemic control call for establishment of prospective cohorts and diabetes registers to monitor the safety and efficacy of different brands of biosimilar insulin and their impacts on clinical outcomes. PMID- 29575726 TI - p53 mediated regulation of coactivator associated arginine methyltransferase 1 (CARM1) expression is critical for suppression of adipogenesis. AB - Coactivator-associated arginine methyltransferase 1 (CARM1/PRMT4) is a type I arginine methyltransferase that mediates transcriptional activation via methylation of histone H3 on R17, R26, and R42. CARM1 is also a coactivator of transcription of various transcription factors such as NF-kB, MEF2C, beta catenin, p53, PPAR-gamma etc. CARM1 has been functionally implicated in maintenance of pluripotency, cellular differentiation, and tumorigenesis; where its expression status plays an important role. Although its expression has been shown to be regulated by a few miRNAs in different contexts at post transcriptional level, transcriptional regulation of CARM1 gene is still unexplored. In this report we demonstrate that CARM1 is a p53 responsive gene, where p53 could suppress CARM1 promoter-driven luciferase expression. CARM1 gene expression was found to be repressed by p53 in 3T3L1 preadipocytes when activated with Nutlin-3a treatment. Ectopic overexpression of CARM1 could rescue inhibitory effect of p53 on adipogenesis, suggesting a role of p53-CARM1 axis of regulation operational in the context of adipocyte differentiation. p53 and CARM1 showed antagonistic regulatory influence on PPAR-gamma expression; which suggests that p53-mediated suppression of adipogenesis could be partly via repression of CARM1 expression. Taken together these observations provide convincing mechanistic explanation for p53 function in the context of adipocyte differentiation process.

As a result, four points can be summarized: Firstly, some of compounds exhibited excellent cytotoxicity activity and selectivity with the IC50 values in single-digit MUm level. In particular, the most promising compound 16d showed equal activity to lead compound foretinib against A549, HepG2, and MCF-7 cell lines, with the IC50 values of 4.79 +/- 0.82, 2.03 +/- 0.39, and 2.90 +/- 0.43 MUm, respectively. Secondly, the SARs and docking studies indicated that the in vitro antitumor activity of pyrrolo[2,3 d]pyrimidine derivatives bearing 1,2,3-triazole moiety was superior to the pyrazolo[3,4-d]pyrimidine derivatives bearing 1,2,3-triazole moiety. Thirdly, three selected compounds (16d, 18d, and 20d) were further evaluated for inhibitory activity against the c-Met kinase, and the 16d could inhibit the c-Met kinase selectively by experiments of enzyme-based selectivity. What is more, 16d could induce apoptosis of HepG2 cells and inhibitor the cell cycle of HepG2 on G2/M phase by acridine orange staining and cell cycle experiments, respectively.

PMID- 29575737 TI - The Impact of Ultrasound on the Use and Efficacy of Intraarticular Glucocorticoid Injections in Early Rheumatoid Arthritis: Secondary Analyses From a Randomized Trial Examining the Benefit of Ultrasound in a Clinical Tight Control Regimen. AB - OBJECTIVE: Intraarticular glucocorticoid injections are common in rheumatoid arthritis (RA) treatment. This study was undertaken to investigate whether ultrasound in combination with clinical examination is better than clinical examination alone at identifying joints that will benefit from intraarticular injections, and to compare the efficacy of ultrasound-guided versus palpation guided procedures. METHODS: In the treat-to-target Aiming for Remission in Rheumatoid Arthritis: a Randomised Trial Examining the Benefit of Ultrasonography in a Clinical Tight Control Regimen (ARCTIC), patients with early RA were randomized 1:1 to follow-up with or without ultrasound. In addition to disease modifying antirheumatic drugs, intraarticular glucocorticoids were used to treat inflamed joints. The distribution of injections was assessed in both study groups. The relationship of clinical and ultrasound findings at the time of injection with treatment efficacy was examined, with non-swollen joint at the next visit as the outcome measure. Treatment success was compared across study groups to evaluate ultrasound-guided versus palpation-guided procedures. RESULTS: More injections were administered in the ultrasound group than in the conventional strategy group (n = 770 versus 548), especially in intercarpal joints (n = 58 versus 5) and metatarsophalangeal joints (n = 200 versus 104). Injecting clinically swollen joints without power Doppler (PD) activity on ultrasound was not efficacious compared to not injecting (odds ratio [OR] 1.3; P = 0.59). Efficacy was best in swollen joints (OR 9.0; P = 0.001) and non-swollen joints (OR 8.4; P = 0.016) with moderate PD activity. Treatment success was similar for the ultrasound-guided and palpation-guided procedures. CONCLUSION: Our findings indicate that the efficacy of intraarticular glucocorticoid injections varies according to ultrasound findings at the time of injection, supporting the use of ultrasound as a tool to select joints that will benefit from intraarticular injections. However, ultrasound needle guidance was not superior to palpation guidance. PMID- 29575738 TI - First live birth after uterus transplantation in the United States. AB - Uterus transplantation has proven to be a successful treatment for women with absolute uterine infertility, caused either by the absence of a uterus or the presence of a nonfunctioning uterus. We report the first birth of a healthy child following uterus transplantation in the United States, from a recipient of a uterus allograft procured from an altruistic living donor. Two major modifications from the previously reported live births characterized this uterus transplant. First, the transplanted uterus relied upon and sustained the pregnancy while having only the utero-ovarian vein as venous outflow. The implication is a significantly simplified living donor surgery that paves the way for minimally invasive laparoscopic or robot-assisted techniques for the donor hysterectomy. Second, the time from transplantation to embryo transfer was significantly shortened from prior protocols, allowing for an overall shorter exposure to immunosuppression by the recipient and lowering the risk for potential adverse effects from these medications. PMID- 29575739 TI - Numerical zero-dimensional hepatic artery hemodynamics model for balloon-occluded transarterial chemoembolization. AB - Balloon-occluded transarterial chemoembolization (B-TACE) is a valuable treatment option for patients with inoperable malignant tumors in the liver. Balloon occluded transarterial chemoembolization consists of the transcatheter infusion of an anticancer drug mixture and embolic agents. Contrary to conventional TACE, B-TACE is performed via an artery-occluding microballoon catheter, which makes the blood flow to redistribute due to the intra- and extrahepatic arterial collateral circulation. Several recent studies have stressed the importance of the redistribution of blood flow in enhancing the treatment outcome. In the present study, the geometries of a representative hepatic artery and the communicating arcades (CAs) are modeled. An in silico zero-dimensional hemodynamic model is created by characterizing the geometry and the boundary conditions and then is validated in vitro. The role of CAs is assessed by combining 2 cancer scenarios and 2 catheter locations. The importance of the diameter of the CAs is also studied. Results show that occluding a main artery leads to collateral circulation and CAs start to play a role in blood-flow redistribution. In summary, numerical zero-dimensional simulations permit a fast and reliable approach for exploring the blood-flow redistribution caused by the occlusion of a main artery, and this approach could be used during B-TACE planning. PMID- 29575740 TI - Stable pneumorectum using an inline glove - a cost-effective technique to facilitate transanal total mesorectal excision. AB - AIM: Transanal total mesorectal excision (taTME) is a novel approach for resection of the rectum. Use of a standard insufflator to create pneumorectum, however, results in bellowing-large heaving motions from insufflation of air that can frustrate surgery. We report the successful application of our technique, stable pneumorectum using an inline glove (SPRING), for the performance of transanal rectal excision in a series of 17 patients using a standard laparoscopic insufflator. METHOD: A retrospective review of 17 patients using the SPRING technique was performed between October 2015 and October 2016. Characteristics of these patients were evaluated, and technique-related short term outcome was reviewed. RESULTS: The SPRING technique was successfully used in patients who underwent both minimally invasive (n = 14) and open (n = 3) approaches in the abdominal stage of the surgery. In the 12 patients who had rectal cancer for whom SPRING was used to facilitate taTME there were no conversions to an alternative access for rectal resection, the median duration of the TME part of the operation was 95 min (62-147) and there was one R1 resection (8%). Billowing was not a significant problem in any of the 17 patients during the surgery. CONCLUSION: In this case series we have successfully shown the feasibility of the SPRING technique as a practical and cost-effective solution to the problem of billowing during taTME.

PMID- 29575743 TI - Potential of Lactobacillus plantarum IBB3036 and Lactobacillus salivarius IBB3154 to persistence in chicken after in ovo delivery. AB - The aim of this study was to characterize and compare selected Lactobacillus strains originating from different environments (cow milk and hen feces) with respect to their applicative potential to colonize gastrointestinal track of chickens before hatching from an egg. In vitro phenotypic characterization of lactobacilli strains included the investigation of the important prerequisites for persistence in gastrointestinal tract, such as a capability to survive in the presence of bile salts and at low pH, enzymatic and sugar metabolic profiles, adhesion abilities, and resistance to osmolytes, temperature, and antibiotics. Regarding the resistance of lactobacilli to most of the various stress factors tested, the milk isolate Lactobacillus plantarum IBB3036 showed better abilities than the chicken feces isolate Lactobacillus salivarius IBB3154. However, regarding the acidification tolerance and adherence ability, L. salivarius IBB3154 revealed better characteristics. Use of these two selected lactobacilli isolates together with proper prebiotics resulted in the preparation of two S1 and S2 bioformulations, which were injected in ovo into hen Cobb500 FF fertilized eggs. Furthermore, in vivo tests assessing the persistence of L. plantarum IBB3036 and L. salivarius IBB3154 in the chicken gastrointestinal tract was monitored by PCR-based classical and quantitative techniques and revealed the presence of both strains in fecal samples collected 3 days after hatching. Subsequently, the number of L. salivarius IBB3154 increased significantly in the chicken intestine, whereas the presence of L. plantarum IBB3036 was gradually decreased. PMID- 29575742 TI - Deregulation of secondary metabolism in a histone deacetylase mutant of Penicillium chrysogenum. AB - The Pc21 g14570 gene of Penicillium chrysogenum encodes an ortholog of a class 2 histone deacetylase termed HdaA which may play a role in epigenetic regulation of secondary metabolism. Deletion of the hdaA gene induces a significant pleiotropic effect on the expression of a set of polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS)-encoding genes. The deletion mutant exhibits a decreased conidial pigmentation that is related to a reduced expression of the PKS gene Pc21 g16000 (pks17) responsible for the production of the pigment precursor naphtha-gamma-pyrone. Moreover, the hdaA deletion caused decreased levels of the yellow pigment chrysogine that is associated with the downregulation of the NRPS-encoding gene Pc21 g12630 and associated biosynthetic gene cluster. In contrast, transcriptional activation of the sorbicillinoids biosynthetic gene cluster occurred concomitantly with the overproduction of associated compounds . A new compound was detected in the deletion strain that was observed only under conditions of sorbicillinoids production, suggesting crosstalk between biosynthetic gene clusters. Our present results show that an epigenomic approach can be successfully applied for the activation of secondary metabolism in industrial strains of P. chrysogenum. PMID- 29575744 TI - Evaluation of information presented within soft tissue sarcoma histopathology reports in the United States: 2012-2015. AB - Despite the existence of the American College of Veterinary Pathology guidelines for tumour biopsy specimens, anecdotally the authors' have seen inconsistency of reporting of information on the pathology report for canine soft tissue sarcomas (STSs). If crucial aspects are not reported this can result in slower or impeded patient care. This retrospective study evaluated 255 STS histopathology reports submitted from across the United States. Reports were evaluated by a single observer to assess for information contained in 5 main categories: patient history and signalment, gross and microscopic description, grading, histologic margins and the comments section. Inclusion criteria for histopathology reports included a final diagnosis of STS, having a microscopic description and resulting from the initial surgical resection. The majority of the reports stated the patient signalment (91.2%) and clinical history (90.8%). However, only 64.8% of the reports had a gross description of the specimen. Histologic margin description was present in 229 reports (91.6%), however, only 149 reports (59.6%) stated an objective measurement of these margins. Histologic classification was stated in 50.0% of the reports, while grade was given on 97.2% of the reports. Variability in histopathologic reporting including histologic margin description for resected canine STS was identified. Given surgical treatment is the mainstay for STS and histopathological assessment plays an important role in determination of whether additional surgery, radiation or chemotherapy is needed. Standardization or checklists like the American College of Pathology utilize may be helpful to ensure histopathologic characteristics are reported that may guide further treatment recommendations. PMID- 29575745 TI - Evaluation of two-dimensional Bruch's membrane opening minimum rim area for glaucoma diagnostics in a large patient cohort. AB - PURPOSE: To characterize the two-dimensional parameter Bruch's membrane opening minimum rim area (BMO-MRA) in spectral domain optical coherence tomography (SD OCT) of the optic nerve head (ONH) compared to minimum rim width (BMO-MRW) and retinal nerve fibre layer (RNFL) thickness in a large patient cohort. METHODS: Case-control, cross-sectional study of 705 eyes of 445 participants. A total of 449 eyes with glaucoma, 67 eyes with ocular hypertension and 189 healthy controls, underwent SD-OCT and confocal laser scanning tomography (CSLT), visual field testing and clinical examination. Morphometric ONH parameters, visual field function and diagnostic power were compared. Main outcome measures were SD-OCT derived BMO-MRA, BMO-MRW, RNFL thickness and CSLT-derived rim area (DM-RA). RESULTS: Mean ONH area was 2.11 +/- 0.57 mm2 ; mean BMO area was 1.89 +/- 0.45 mm2 . Correlation of mean deviation in visual field to morphometric parameters was rho = 0.70, (p < 0.001) for RNFL thickness, rho = 0.68 (p < 0.001) for BMO MRA, rho = 0.66 (p < 0.001) for BMO-MRW. These correlations were not significantly different (p > 0.05), while DM-RA correlated significantly worse (rho = 0.55; p < 0.001). In receiver operating characteristics, the calculated area under the curve (AUC) and sensitivity at 90% specificity to differentiate glaucoma were 0.87% and 70.1% for BMO-MRA, 0.86% and 68.1% for RNFL thickness, 0.84% and 66.0% for BMO-MRW, 0.82% and 51.3% for DM-RA. CONCLUSIONS: In a heterogenous clinical cohort of glaucoma patients, all analysed SD-OCT parameters excel DM-RA of CSLT. The two-dimensional parameter BMO-MRA shows comparable levels of diagnostic power to detect glaucoma compared to established parameters BMO-MRW and RNFL thickness. Given higher comparability between ONH sizes, BMO-MRA might become an additional standard tool in SD-OCT imaging for glaucoma. PMID- 29575746 TI - Experience of associative stigma in parents of adolescents at risk for psychosis. AB - AIM: This qualitative study examined the lived experience of associative stigma for parents of adolescents at clinical high risk for psychosis. A central goal was to empower families to tell their stories and to use the themes that emerge from this narrative data to make recommendations that might support families coping with a loved one being diagnosed with risk for psychosis. METHODS: Twelve parents of adolescents diagnosed with the clinical high risk for psychosis syndrome were interviewed using a semi-structured approach. The qualitative study employed Interpretative Phenomenological Analysis (IPA) to focus on experiences of associative stigma and the way parents make sense of these experiences. RESULTS: From these interviews, the researcher identified themes and subthemes categorized into major domains that represent topics particularly relevant to these 12 parents. Two main domains emerged as particularly salient to parents' experiences with associative stigma: perceptions of stigma and coping with stigma. CONCLUSIONS: Participants' insights demonstrated increased experience of stigma associated with psychotic-like symptoms as compared to other psychiatric symptoms, attempts to balance fighting against stigma with the privacy needs of adolescents, and participation in research as less stigmatizing than non specialty care. Stigma impacted treatment-seeking and participation in family groups that were seen as both potentially supportive and threatening. The interviews provided an opportunity for these families to voice their unique experiences, which expands the literature on the topic of caregivers of adolescents at risk for psychosis as treatment programs for the clinical high risk syndrome expand across the United States. PMID- 29575748 TI - Porous Cobalt Oxynitride Nanosheets for Efficient Electrocatalytic Water Oxidation. AB - Exploring efficient and cheap oxygen evolution reaction (OER) electrocatalysts is of great significance for electrochemical water splitting. Herein, we successfully prepared an efficient ternary electrocatalyst of porous cobalt oxynitride (Co3 Ox Ny ) nanosheets by a simple nitridation strategy. Specifically, CoON PNS-400 (cobalt oxynitride with porous nanosheet structure obtained at 400 o C) offered a low OER overpotential of 0.23 V to achieve the catalytic current density of 10 mA cm-2 and a small Tafel slope of 48 mV dec-1 in alkali media, outperforming most of the first-row transition-metal-based OER electrocatalysts. The calculated density of states (DOS) analysis and electron spin resonance (ESR) measurements revealed that the introduction of foreign N atoms into pristine Co3 O4 nanosheets can optimize the electronic structure and create more oxygen vacancies, thus leading to enhanced electrical conductivity. Density functional theory (DFT) calculations demonstrated that the foreign N atoms can also improve the energetics for OER by modulating the free energy for adsorbed intermediates (OOH*, OH*, O*), further improving the OER electrocatalytic activity of CoON PNS-400. This work provides a possibility for rationally designing ternary transition-metal compounds as advanced OER electrocatalysts.

PMID- 29575750 TI - Let's talk about sex: A rigorous statistical framework to assign the sex of individuals from reduced-representation sequencing data. AB - Molecular markers have been used to identify the sex of sampled individuals for several decades, but the time-consuming development phase prevented their application in many systems. Recently, a growing number of papers have applied reduced-representation sequencing (RRS) protocols to the identification of sex specific markers without the use of test crosses or prior genomic information. While such an approach has great advantages in terms of versatility and ease of use, the "shotgun sequencing" nature of RRS data sets leads to a high amount of missing data, which results in statistical challenges to the confident assignment of sex to individuals. In this issue of Molecular Ecology Resources, Stovall et al. (Molecular Ecology Resources, 18, 2018) provide a statistical framework to answer two questions: (1) how many individuals of one sex only must possess a genotype for this locus to be considered significantly sex-specific? and (2) How many sex-specific loci must an individual of unknown sex possess (in a given data set) to be confidently assigned a sex? The statistical pipeline introduced, and applied to samples of New Zealand fur seal (Arctocephalus forsteri) to identify 90 sex-specific loci, should be broadly applicable to a large number of species and constitutes a nice addition to the molecular ecology toolkit in the genomics era. PMID- 29575751 TI - Numerical approximation of the electromechanical coupling in the left ventricle with inclusion of the Purkinje network. AB - In this work, we consider the numerical approximation of the electromechanical coupling in the left ventricle with inclusion of the Purkinje network. The mathematical model couples the 3D elastodynamics and bidomain equations for the electrophysiology in the myocardium with the 1D monodomain equation in the Purkinje network. For the numerical solution of the coupled problem, we consider a fixed-point iterative algorithm that enables a partitioned solution of the myocardium and Purkinje network problems. Different levels of myocardium-Purkinje network splitting are considered and analyzed. The results are compared with those obtained using standard strategies proposed in the literature to trigger the electrical activation. Finally, we present a numerical study that, although performed in an idealized computational domain, features all the physiological issues that characterize a heartbeat simulation, including the initiation of the signal in the Purkinje network and the systolic and diastolic phases. PMID- 29575752 TI - Rapid on-site evaluation using telecytology: A major cancer center experience. AB - BACKGROUND: Rapid on-site evaluation (ROSE) with cytology preparations plays a critical role in minimally invasive procedures. The time spent by a pathologist performing ROSE is unpredictable and could be used for more cost-effective activities. The solution encountered by several institutions to address this issue is the use of telecytology (TC). This study analyzes the experience of using telecytology for ROSE in a major cancer center over a period of over 2 years. METHODS: A retrospective analysis of all remote TC evaluations for adequacy on fine needle aspiration (FNA) and touch preparations (TP) of core biopsies (CB) performed at a major cancer center was performed. The preliminary adequacy assessment was then compared to the adequacy assessment at final diagnosis. RESULTS: A total of 12 949 adequacy assessments were analyzed. The most common sites biopsied in our institution were lymph node, lung, and liver. There were 7725 adequacy assessments for CB (59.7%), while adequacy assessment for FNA specimens represented 40.3% (n = 5224) of the total number of specimens evaluated by ROSE. Perfect concordance between initial adequacy assessment and the adequacy assessment at final cytologic diagnosis was 93% (12 049/12 949). The final diagnosis adequacy upgrade rate was 6.7% (n = 863), and the adequacy downgrade (a specimen considered adequate on-site that was determined to be nondiagnostic on final examination) was 0.3% (n = 37). CONCLUSIONS: TC can be easily implemented with the current technologies available. It is cost-effective and allows for better patient care with a more efficient use of the pathologist's time and laboratory resources. PMID- 29575753 TI - A graphical method for comparing nocturnal oxygen saturation profiles in individuals and populations: Application to healthy infants and preterm neonates. AB - STUDY OBJECTIVES: Pulse-oximetry (SpO2 ) allows the identification of important clinical physiology. However, summary statistics such as mean values and desaturation incidence do not capture the complexity of the information contained within continuous recordings. The aim of this study was to develop an objective method to quantify important SpO2 characteristics; and assess its utility in healthy infant and preterm neonate cohorts. METHODS: An algorithm was developed to calculate the desaturation incidence, depth, and duration. These variables are presented using three plots: SpO2 cumulative-frequency relationship; desaturation depth versus incidence; desaturation-duration versus incidence. This method was applied to two populations who underwent nocturnal pulse-oximetry: (1) thirty four healthy term infants studied at 2-weeks, 3, 6, 12, and 24-months of age and (2) thirty-seven neonates born <26 weeks and studied at discharge from NICU (37 44 weeks post-conceptual age). RESULTS: The maturation in healthy infants was characterized by reduced desaturation index (27.2/h vs 3.3/h at 2-weeks and 24 months, P < 0.01), and increased percentage of desaturation events >=6-s in duration (27.8% vs 43.2% at 2-weeks and 3-months, P < 0.01). Compared with term infants, preterm infants had a greater desaturation incidence (54.8/h vs 27.2/h, P < 0.01), and these desaturations were deeper (52.9% vs 37.6% were >=6% below baseline, P < 0.01). The incidence of longer desaturations (>=14-s) in preterm infants was correlated with healthcare utilization over the first 24-months (r = 0.63, P < 0.01). CONCLUSIONS: This tool allows the objective comparison of extended oximetry recordings between groups and for individuals; and serves as a basis for the development of reference ranges for populations. PMID- 29575754 TI - Optimization of Pyrazoles as Phenol Surrogates to Yield Potent Inhibitors of Macrophage Migration Inhibitory Factor. AB - Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that is implicated in the regulation of inflammation, cell proliferation, and neurological disorders. MIF is also an enzyme that functions as a keto-enol tautomerase. Most potent MIF tautomerase inhibitors incorporate a phenol, which hydrogen bonds to Asn97 in the active site. Starting from a 113-MUm docking hit, we report results of structure-based and computer-aided design that have provided substituted pyrazoles as phenol alternatives with potencies of 60-70 nm. Crystal structures of complexes of MIF with the pyrazoles highlight the contributions of hydrogen bonding with Lys32 and Asn97, and aryl-aryl interactions with Tyr36, Tyr95, and Phe113 to the binding. PMID- 29575755 TI - Peri-implant parameters, tumor necrosis factor-alpha, and interleukin-1 beta levels in vaping individuals. AB - BACKGROUND: To the author's knowledge, there has been no study that has assessed clinical, radiographic, and immunological peri-implant parameters among individuals vaping e-cigarette (e-cig). PURPOSE: This pilot study aimed to compare clinical and radiographic peri-implant parameters and levels of tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-1beta levels among individuals vaping e-cigs and never smoker (NS). MATERIALS AND METHODS: Forty seven individuals vaping e-cigs (group-1) and 45 NS (group-2) were included. Demographic and implant-related data were collected using a structured baseline questionnaire. Peri-implant plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were recorded and peri-implant bone loss (PIBL) were assessed using standardized digital radiographs. Enzyme-linked immunosorbent assay was used to assess the levels of TNF-alpha and IL-1beta in peri-implant sulcular fluid. RESULTS: Bleeding on probing showed statistically significantly higher values in group-2 patients as compared to group-1 patients (P < .01). Probing depth >= 4 mm and PIBL was statistically significantly higher in group-1 patients as compared to group-2 patients (P < .05). Mean concentrations of TNF-alpha (P < .001) and IL-1beta (P < .01) were statistically significantly increased in individuals in group 1 as compared with group 2. A significant positive correlations were found between TNF-alpha levels and BOP (P = .024) and PIBL (P = .016); and significant positive correlation was found between IL-1beta and PIBL (P = .018) in group 1, respectively. CONCLUSIONS: Clinical and radiographic peri implant parameters are compromised among vaping individuals. Increased levels of proinflammatory cytokines in peri-implant sulcular fluid may suggest greater local inflammatory response in vaping individuals for peri-implant inflammation.

AB - The renin-angiotensin system (RAS), a crucial regulator of systemic blood pressure (circulatory RAS), plays distinct roles in pathological angiogenesis and inflammation in various organs (tissue RAS), such as diabetic microvascular complications. Using ocular clinical samples and animal disease models, we elucidated molecular mechanisms in which tissue RAS excites the expression of vascular endothelial growth factor (VEGF)-A responsible for retinal inflammation and angiogenesis, the two major pathological events in diabetic retinopathy (DR). Furthermore, we showed the involvement of (pro)renin receptor [(P)RR] in retinal RAS activation and its concurrent intracellular signal transduction (e.g., extracellular signal-regulated kinase); namely, the (P)RR-induced dual pathogenic bioactivity referred to as the receptor-associated prorenin system. Indeed, neovascular endothelial cells in the fibrovascular tissue collected from eyes with proliferative DR were immunoreactive for the receptor-associated prorenin system components including prorenin, (P)RR, phosphorylated extracellular signal regulated kinase and VEGF-A. Protein levels of soluble (P)RR increased with its positive correlations with prorenin, renin enzymatic activity and VEGF in the vitreous of proliferative DR eyes, suggesting a close link between (P)RR and VEGF A-driven angiogenic activity. Furthermore, we revealed an unsuspected, PAPS independent role of (P)RR in glucose-induced oxidative stress. Recently, we developed an innovative single-strand ribonucleic acid interference molecule selectively targeting human and mouse (P)RR, and confirmed its efficacy in suppressing diabetes-induced retinal inflammation in mice. Our data using clinical samples and animal models suggested the significant implication of (P)RR in the pathogenesis of DR, and the potential usefulness of the ribonucleic acid interference molecule as a therapeutic agent to attenuate ocular inflammation and angiogenesis. PMID- 29575758 TI - A selenoprotein T-derived peptide protects the heart against ischaemia/reperfusion injury through inhibition of apoptosis and oxidative stress. AB - AIM: Selenoprotein T (SelT or SELENOT) is a novel thioredoxin-like enzyme whose genetic ablation in mice results in early embryonic lethality. SelT exerts an essential cytoprotective action during development and after injury through its redox-active catalytic site. This study aimed to determine the expression and regulation of SelT in the mammalian heart in normal and pathological conditions and to evaluate the cardioprotective effect of a SelT-derived peptide, SelT43 52(PSELT) encompassing the redox motif which is key to its function, against ischaemia/reperfusion(I/R) injury. METHODS: We used the isolated Langendorff rat heart model and different analyses by immunohistochemistry, Western blot and ELISA. RESULTS: We found that SelT expression is very abundant in embryo but is undetectable in adult heart. However, SelT expression was tremendously increased after I/R. PSELT (5 nmol/L) was able to induce pharmacological post-conditioning cardioprotection as evidenced by a significant recovery of contractility (dLVP) and reduction of infarct size (IS), without changes in cardiac contracture (LVEDP). In contrast, a control peptide lacking the redox site did not confer cardioprotection. Immunoblot analysis showed that PSELT-dependent cardioprotection is accompanied by a significant increase in phosphorylated Akt, Erk-1/2 and Gsk3alpha-beta, and a decrement of p38MAPK. PSELT inhibited the pro apoptotic factors Bax, caspase 3 and cytochrome c and stimulated the anti apoptotic factor Bcl-2. Furthermore, PSELT significantly reduced several markers of I/R-induced oxidative and nitrosative stress. CONCLUSION: These results unravel the role of SelT as a cardiac modulator and identify PSELT as an effective pharmacological post-conditioning agent able to protect the heart after ischaemic injury. PMID- 29575759 TI - Assessment of acute toxicity tests and rhizotron experiments to characterize lethal and sublethal control of soil-based pests. AB - BACKGROUND: Characterizing lethal and sublethal control of soil-based pests with plant protection products is particularly challenging due to the complex and dynamic interplay of the system components. Here, we present two types of studies: acute toxcity experiments (homogenous exposure of individuals in soil) and rhizotron experiments (heterogeneous exposure of individuals in soil) to investigate their ability to strengthen our understanding of mechanisms driving the effectivness of the plant protection product. Experiments were conducted using larvae of the western corn rootworm Diabrotica virgifera LeConte and three pesticide active ingredients: clothianidin (neonicotinoid), chlorpyrifos (organophosphate) and tefluthrin (pyrethroid). RESULTS: The order of compound concentrations needed to invoke a specific effect intensity (EC50 values) within the acute toxicity tests was chlorpyrifos > tefluthrin > clothianidin. This order changed for the rhizotron experiments because application type, fate and transport of the compounds in the soil profile, and sublethal effects on larvae also influence their effectiveness in controlling larval feeding on corn roots. CONCLUSION: Beyond the pure measurement of efficacy through observing relative changes in plant injury to control plants, the tests generate mechanistic understanding for drivers of efficacy apart from acute toxicity. The experiments have the potential to enhance efficacy testing and product development, and might be useful tools for assessing resistance development in the future.

PMID- 29575760 TI - Analysis of the activity and safety of weekly low-dose bevacizumab-based regimens in heavily pretreated patients with metastatic breast cancer. AB - BACKGROUND: Currently, there are no standard regimens for metastatic breast cancer patients (MBC) who have failed >= 3 chemotherapy treatments. The aim of this study was to assess whether weekly low-dose bevacizumab-based regimens were well tolerated and would improve efficacy in MBC patients who had failed numerous therapies. METHODS: Seventeen patients with MBC who were heavily pretreated with a median of five regimens of therapy (range 1-10) between 2012 and 2016 were included in the analysis. Bevacizumab was administered at a dose of 100 mg intravenously once a week combined with one or two types of chemotherapeutic drugs until confirmed disease progression or an intolerable adverse event was observed. Patient characteristics, objective response rate, clinical benefit rate, progression-free survival, and toxicity were assessed. RESULTS: All 17 patients had been pretreated with taxane-based and anthracycline-based chemotherapy. Weekly low-dose bevacizumab combined with one or two types of chemotherapeutic drugs, which had usually not been previously used (e.g. etoposide, irinotecan, pemetrexed, methotrexate, and nab-paclitaxel), was administered. Three patients achieved a partial response, while one had stable disease for > 24 weeks, and the clinical benefit rate was 23.5%. Median progression-free survival was 3.4 months (95% confidence interval 2.0-4.8). The most common hematological adverse events were neutropenia, anemia, and thrombocytopenia. Bevacizumab-related adverse events included grade 1 bleeding (17.6%) and grade 2 hypertension (5.9%). CONCLUSIONS: Weekly low-dose bevacizumab combined with chemotherapy shows a relatively favorable clinical response and tolerable toxicity, providing a feasible option for heavily pretreated MBC patients.

PMID- 29575763 TI - DNA methylation profiling reveals a pathological signature that contributes to transcriptional defects of CD34+ CD15- cells in early chronic-phase chronic myeloid leukemia. AB - Despite the high efficiency of tyrosine kinase inhibitors (TKI), some patients with chronic myeloid leukemia (CML) will display residual disease that can become resistant to treatment, indicating intraclonal heterogeneity in chronic-phase CML (CP-CML). To determine the basis of this heterogeneity, we conducted the first exhaustive characterization of the DNA methylation pattern of sorted CP-CML CD34+ CD15- (immature) and CD34- CD15+ (mature) cells at diagnosis (prior to any treatment) and compared it to that of CD34+ CD15- and CD34- CD15+ cells isolated from healthy donors (HD). In both cell types, we identified several hundreds of differentially methylated regions (DMRs) showing DNA methylation changes between CP-CML and HD samples, with only a subset of them in common between CD34+ CD15- and CD34- CD15+ cells. This suggested DNA methylation variability within the same CML clone. We also identified 70 genes that could be aberrantly repressed upon hypermethylation and 171 genes that could be aberrantly expressed upon hypomethylation of some of these DMRs in CP-CML cells, among which 18 and 81, respectively, were in CP-CML CD34+ CD15- cells only. We then validated the DNA methylation and expression defects of selected candidate genes. Specifically, we identified GAS2, a candidate oncogene, as a new example of gene the hypomethylation of which is associated with robust overexpression in CP-CML cells. Altogether, we demonstrated that DNA methylation abnormalities exist at early stages of CML and can affect the transcriptional landscape of malignant cells. These observations could lead to the development of combination treatments with epigenetic drugs and TKI for CP-CML. PMID- 29575765 TI - Combination therapy of apatinib with icotinib for primary acquired icotinib resistance in patients with advanced pulmonary adenocarcinoma with EGFR mutation. AB - Multi-targeted agents represent the next generation of targeted therapies for solid tumors, and patients with acquired resistance to EGFR-tyrosine kinase inhibitors (TKIs) may also benefit from their combination with TKI therapy. Third generation targeted drugs, such as osimertinib, are very expensive, thus a more economical solution is required. The aim of this study was to explore the use of apatinib combined with icotinib therapy for primary acquired resistance to icotinib in three patients with advanced pulmonary adenocarcinoma with EGFR mutations. We achieved favorable oncologic outcomes in all three patients, with progression-free survival of four to six months. Unfortunately, the patients ultimately had to cease combination therapy because of intolerable adverse effects of hand and foot syndrome and oral ulcers. Combination therapy of apatinib with icotinib for primary acquired resistance to icotinib may be an option for patients with advanced pulmonary adenocarcinoma with EGFR mutations, but physicians must also be aware of the side effects caused by such therapy.

AB - Plaque modification devices are used to treat heavily calcified coronary artery lesions during percutaneous coronary artery interventions. As these devices have unique risk profiles, clinicians need to be aware of potential complications associated with their use. A case of a contained rupture (i.e., pseudoaneurysm) of the proximal left main coronary artery following orbital atherectomy is presented. This lesion was managed with coronary artery bypass grafting and oversewing of the left main coronary artery ostium. This case illustrates that lesion location and configuration may influence tracking of these devices, as well as the actual site of tissue ablation. This case underscores the importance of concurrent imaging during treatment and concern for potential unintended consequences of atherectomy. PMID- 29575767 TI - Structure and Bonding in CE5- (E=Al-Tl) Clusters: Planar Tetracoordinate Carbon versus Pentacoordinate Carbon. AB - The structure, bonding, and stability of clusters with the empirical formula CE5- (E=Al-Tl) have been analyzed by means of high-level computations. The results indicate that, whereas aluminum and gallium clusters have C2v structures with a planar tetracoordinate carbon (ptC), their heavier homologues prefer three dimensional C4v forms with a pentacoordinate carbon center over the ptC one. The reason for such a preference is a delicate balance between the interaction energy of the fifth E atom with CE4 and the distortion energy. Moreover, bonding analysis shows that the ptC systems can be better described as CE4- , with 17 valence electrons interacting with E. The ptC core in these systems exhibits double aromatic (both sigma and pi) behavior, but the sigma contribution is dominating.

AB - : An open-label, single-dose, randomized, two-period, crossover study comparing the pharmacokinetics of factor VIII activity in plasma (FVIII:C) after administration of an albumin-free presentation of moroctocog alfa (test) and moroctocog alfa manufactured using the previous technique (reference) was conducted in 30 (25 evaluable) male subjects who had severe hemophilia A (FVIII:C < 1 IU/dL). Blood samples were collected for 48 h after administration of each dose. FVIII: C was assayed using a chromogenic substrate assay. The FVIII:C pharmacokinetic parameters were calculated using noncompartmental analysis. The presentations would be bioequivalent if the 90% confidence limits of the ratio of the geometric mean values of AUCinf and recovery fell within the interval of 80 125%. The bioequivalence criteria were met. A total of 10 treatment-related adverse events were observed in a total of nine subjects. All were mild and none was determined to be related to administration of study medication. PMID- 29575772 TI - LncRNA SNHG1 functions as a ceRNA to antagonize the effect of miR-145a-5p on the down-regulation of NUAK1 in nasopharyngeal carcinoma cell. AB - How lncRNA SNHG1 influences the aggressiveness of nasopharyngeal carcinoma cells as well as the underlying mechanism was studied. The lncRNA differences were analysed by GSE12452 gene microarray. The expression of SNHG1, MiR-145-5p and NUAK1 was identified by qRT-PCR and western blot. Transfection was conducted to construct nasopharyngeal carcinoma cells with different expressions of SNHG1, miR 145-5p and NUAK1. Dual-luciferase reporter assay was performed to explore the relationship between SNHG1, miR-145-5p and NUAK1. Wound-healing assay and transwell invasion experiments were employed to study changes in cell migration capacity and cell invasion, respectively. Tumour xenografts were performed to observe lung metastasis of nude mice inoculated with transfected CNE cells. SNHG1 is highly expressed in nasopharyngeal carcinoma tissues and in cell lines. Down regulation of SNHG1 facilitated the expression of miR-145-5p and further suppressed the level of NAUK1 in CNE and HNE-1 cells. Silencing of SNHG1, up regulation of miR-145-5p and inhibition of NAUK1 by relative transfection all attenuated the aggressiveness of CNE and HNE-1 cells both in vivo and in vitro. Moreover, the impaired cell migration and invasion by SNHG1 siRNA could be rescued by cotransfection of miR-145-5p in CNE and HNE-1 cells. LncRNA SNHG1 promoted the expression of NUAK1 by down-regulating miR-145-5p and thus promoted the aggressiveness of nasopharyngeal carcinoma cells through AKT signalling pathway and induced epithelial-mesenchymal transition (EMT). PMID- 29575771 TI - The habenula as a novel link between the homeostatic and hedonic pathways in cancer-associated weight loss: a pilot study. AB - BACKGROUND: Little is known about the brain mechanisms underlying cancer associated weight loss (C-WL) in humans despite this condition negatively affecting their quality of life and survival. We tested the hypothesis that patients with C-WL have abnormal connectivity in homeostatic and hedonic brain pathways together with altered brain activity during food reward. METHODS: In 12 patients with cancer and 12 healthy controls, resting-state functional connectivity (RSFC, resting brain activity observed through changes in blood flow in the brain which creates a blood oxygen level-dependent signal that can be measured using functional magnetic resonance imaging) was used to compare three brain regions hypothesized to play a role in C-WL: the hypothalamus (homeostatic), the nucleus accumbens (hedonic), and the habenula (an important regulator of reward). In addition, the brain reward response to juice was studied. Participants included 12 patients with histological diagnosis of incurable cancer (solid tumours), a European Cooperative Oncology Group performance status of 0-2, and a >=5% involuntary body weight loss from pre illness over the previous 6 months and 12 non-cancer controls matched for age, sex, and race. RSFC between the hypothalamus, nucleus accumbens, and habenula and brain striatum activity as measured by functional MRI during juice reward delivery events were the main outcome measures. RESULTS: After adjusting for BMI and compared with matched controls, patients with C-WL were found to have reduced RSFC between the habenula and hypothalamus (P = 0.04) and between the habenula and nucleus accumbens (P = 0.014). Patients with C-WL also had reduced juice reward responses in the striatum compared with controls. CONCLUSIONS: In patients with C-WL, reduced connectivity between both homeostatic and hedonic brain regions and the habenula and reduced juice reward were observed. Further research is needed to establish the relevance of the habenula and striatum in C-WL. PMID- 29575773 TI - Non-invasive ventilation practices in children across Europe. AB - OBJECTIVES: To describe the diversity in practice in non-invasive ventilation (NIV) in European pediatric intensive care units (PICUs). WORKING HYPOTHESIS: No information about the use of NIV in Pediatrics across Europe is currently available, and there might be a wide variability regarding the approach. STUDY DESIGN: Cross-sectional electronic survey. METHODOLOGY: The survey was distributed to the ESPNIC mailing list and to researchers in different European centers. RESULTS: One hundred one units from 23 countries participated. All respondent units used NIV. Almost all PICUs considered NIV as initial respiratory support (99.1%), after extubation (95.5% prophylactically, 99.1% therapeutically), and 77.5% as part of palliative care. Overall NIV use outside the PICUs was 15.5% on the ward, 20% in the emergency department, and 36.4% during transport. Regarding respiratory failure cause, NIV was delivered in pneumonia (97.3%), bronchiolitis (94.6%), bronchospasm (75.2%), acute pulmonary edema (84.1%), upper airway obstruction (76.1%), and in acute respiratory distress syndrome (91% if mild, 53.1% if moderate, and 5.3% if severe). NIV use in asthma was less frequent in Northern European units in comparison to Central and Southern European PICUs (P = 0.007). Only 47.7% of the participants had a written protocol about NIV use. Bilevel NIV was applied mostly through an oronasal mask (44.4%), and continuous positive airway pressure through nasal cannulae (39.8%). If bilevel NIV was required, 62.3% reported choosing pressure support (vs assisted pressure-controlled ventilation) in infants; and 74.5% in older children. CONCLUSIONS: The present study shows that NIV is a widespread technique in European PICUs. Practice across Europe is variable. PMID- 29575774 TI - Silk fibroin enhances peripheral nerve regeneration by improving vascularization within nerve conduits. AB - Silk fibroin (SF)-based nerve conduits have been widely used to bridge peripheral nerve defects. Our previous study showed that nerve regeneration in a SF-blended poly (l-lactide-co-E-caprolactone) [P(LLA-CL)] nerve conduit is better than that in a P(LLA-CL) conduit. However, the involved mechanisms remain unclarified. Because angiogenesis within a nerve conduit plays an important role in nerve regeneration, vascularization of SF/P(LLA-CL) and P(LLA-CL) conduits was compared both in vitro and in vivo. In the present study, we observed that SF/P(LLA-CL) nanofibers significantly promoted fibroblast proliferation, and vascular endothelial growth factor secreted by fibroblasts seeded in SF/P(LLA-CL) nanofibers was more than seven-fold higher than that in P(LLA-CL) nanofibers. Conditioned medium of fibroblasts in the SF/P(LLA-CL) group stimulated more human umbilical vein endothelial cells (HUVEC) to form capillary-like networks and promoted faster HUVEC migration. The two kinds of nerve conduits were used to bridge 10-mm-length nerve defects in rats. At 3 weeks of reparation, the blood vessel area in the SF/P(LLA-CL) group was significantly larger than that in the P(LLA-CL) group. More regenerated axons and Schwann cells were also observed in the SF/P(LLA-CL) group, which was consistent with the results of blood vessels. Collectively, our data revealed that the SF/P(LLA-CL) nerve conduit enhances peripheral nerve regeneration by improving angiogenesis within the conduit. (c) 2018 Wiley Periodicals, Inc.

AB - Deletions and duplications, called reciprocal CNVs when they occur at the same locus, are implicated in neurodevelopmental phenotypes ranging from morphological to behavioral. In this article, we propose three models of how differences in gene expression in deletion and duplication genotypes may result in deleterious phenotypes. To explore these models, we use examples of the similarities and differences in clinical phenotypes of five reciprocal CNVs known to cause neurodevelopmental disorders: 1q21.1, 7q11.23, 15q13.3, 16p11.2, and 22q11.2. These models and examples may inform some insights into better understanding of gene-phenotype relationships. (c) 2018 Wiley Periodicals, Inc. Develop Neurobiol 78: 519-530, 2018. PMID- 29575776 TI - Quantitative Analysis of Multiple Proteins of Different Invasive Tumor Cell Lines at the Same Single-Cell Level. AB - Tumor cell invasion is pivotal to the development, metastasis, and prognosis of tumors. It is reported that the invasive ability of tumor cells is mainly dependent on the expression levels of membrane type-1 matrix metalloproteinase (MT1-MMP) and integrin alphaV beta3 proteins on cell membranes. To precisely distinguish between tumor cells with different invasive abilities, it is important to establish a highly sensitive and precise quantification method to differentiate the expression levels of MT1-MMP and integrin alphaV beta3 in the same single tumor cell at the same time. Herein, two functional peptides to construct red-emissive Au26 clusters and green-emissive Ag12 clusters are reported. Moreover, the Au26 clusters and Ag12 clusters have the ability to specifically target MT1-MMP and integrin alphaV beta3 , respectively, in the same single cell at the same time. By utilizing the fluorescent properties and metallic compositions of metal clusters, the MT1-MMP and integrin alphaV beta3 levels of the more invasive SiHa cells or the less invasive HeLa cells are simultaneously and quantitatively differentiated via laser ablation inductively coupled plasma mass spectrometry. This method of quantitatively detecting multiple invasive proteins on the same cell is of great value for accurately diagnosing aggressive tumors and monitoring the invasiveness of these tumors. PMID- 29575777 TI - Phylogeography of Diaphorina citri (Hemiptera: Liviidae) and its primary endosymbiont, 'Candidatus Carsonella ruddii': an evolutionary approach to host endosymbiont interaction. AB - BACKGROUND: In insects, little is known about the co-evolution between their primary endosymbionts and hosts at the intraspecific level. This study examined co-diversification between the notorious agricultural pest Diaphorina citri and its primary endosymbionts (P-endosymbiont), 'Candidatus Carsonella ruddii' at the population level. RESULTS: Maximum likelihood, haplotype network, principal components and Bayesian clustering identified three lineages for D. citri and its P-endosymbiont: a Western clade containing individuals from Pakistan, Bhutan (Phuentsholing), Vietnam (Son La), USA, Myanmar and China (Ruili, Yunnan); a Central clade, with accessions originating from Southwest China, Bhutan (Tsirang) and Bangladesh; and an Eastern clade containing individuals from Southeast Asia, and East and South China. A more diverse genetic structure was apparent in the host mitochondrial DNA than their P-endosymbionts; however, the two sets of data were strongly congruent. CONCLUSION: This study provides evidence for the co diversification of D. citri and its P-endosymbiont during the migration from South Asia to East and Southeast Asia. We also suggest that the P-endosymbiont may facilitate investigations into the genealogy and migration history of the host. The biogeography of D. citri and its P-endosymbiont indicated that D. citri colonized and underwent a secondary dispersal from South Asia to East and Southeast Asia.

PMID- 29575778 TI - Signal transducer and activator of transcription 3 overexpression promotes lymph node micrometastasis in early-stage non-small cell lung cancer. AB - BACKGROUND: Signal transducer and activator of transcription 3 (STAT3) is constitutively activated in several malignancies. Here, we define the correlation between STAT3 expression and lymph node micrometastasis of early-stage non-small cell lung cancer. Then we highlight some possibilities associated with developing a way to detect tumor micrometastasis and an anticancer drug that might therapeutically inhibit the STAT3 signaling pathway. METHODS: The samples were collected from 50 patients with early-stage non-small cell lung cancer and 50 patients with benign lung tumors. Mucin 1 mRNA expression was evaluated to determine lymph node micrometastasis status. STAT3 mRNA, STAT3 protein, and phosphorylated STAT3 protein expression were evaluated through reverse transcription polymerase chain reaction, western blot, and immunohistochemistry, respectively. Measurement data was represented as mean +/- standard deviation, and the t-rest or F-test were used. The chi2 -test was used in enumeration data. Logistic regression analysis was carried out to determine the independent risk factors influencing lymph node micrometastasis. RESULTS: STAT3 mRNA and proteins expression were correlated with lymph node micrometastasis (P < 0.05). Logistic regression analysis revealed STAT3 protein overexpression and the differentiation degree of tumors were independent risk factors for lymph node micrometastasis. CONCLUSION: Overexpression of STAT3 might promote lymphatic micrometastasis of early-stage non-small cell lung cancer and might be a clinical predictor of lymph node micrometastasis. PMID- 29575779 TI - Accumulating Data to Optimally Predict Obesity Treatment (ADOPT) Core Measures: Environmental Domain. AB - BACKGROUND: There is growing interest in how environment is related to adults' weight and activity and eating behaviors. However, little is known about whether environmental factors are related to the individual variability seen in adults' intentional weight loss or maintenance outcomes. OBJECTIVES: The environmental domain subgroup of the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project sought to identify a parsimonious set of objective and perceived neighborhood and social environment constructs and corresponding measures to include in the assessment of response to adult weight-loss treatment. SIGNIFICANCE: Starting with the home address, the environmental domain subgroup recommended for inclusion in future weight-loss or maintenance studies constructs and measures related to walkability, perceived land use mix, food outlet accessibility (perceived and objective), perceived food availability, socioeconomics, and crime-related safety (perceived and objective) to characterize the home neighborhood environment. The subgroup also recommended constructs and measures related to social norms (perceived and objective) and perceived support to characterize an individual's social environment. The 12 neighborhood and social environment constructs and corresponding measures provide a succinct and comprehensive set to allow for more systematic examination of the impact of environment on adults' weight loss and maintenance. PMID- 29575780 TI - The Accumulating Data to Optimally Predict Obesity Treatment (ADOPT) Core Measures Project: Rationale and Approach. AB - BACKGROUND: Individual variability in response to multiple modalities of obesity treatment is well documented, yet our understanding of why some individuals respond while others do not is limited. The etiology of this variability is multifactorial; however, at present, we lack a comprehensive evidence base to identify which factors or combination of factors influence treatment response. OBJECTIVES: This paper provides an overview and rationale of the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project, which aims to advance the understanding of individual variability in response to adult obesity treatment. This project provides an integrated model for how factors in the behavioral, biological, environmental, and psychosocial domains may influence obesity treatment responses and identify a core set of measures to be used consistently across adult weight-loss trials. This paper provides the foundation for four companion papers that describe the core measures in detail. SIGNIFICANCE: The accumulation of data on factors across the four ADOPT domains can inform the design and delivery of effective, tailored obesity treatments. ADOPT provides a framework for how obesity researchers can collectively generate this evidence base and is a first step in an ongoing process that can be refined as the science advances. PMID- 29575781 TI - Accumulating Data to Optimally Predict Obesity Treatment (ADOPT) Core Measures: Psychosocial Domain. AB - BACKGROUND: Within the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project, the psychosocial domain addresses how psychosocial processes underlie the influence of obesity treatment strategies on weight loss and weight maintenance. The subgroup for the psychosocial domain identified an initial list of high-priority constructs and measures that ranged from relatively stable characteristics about the person (cognitive function, personality) to dynamic characteristics that may change over time (motivation, affect). OBJECTIVES: This paper describes (a) how the psychosocial domain fits into the broader model of weight loss and weight maintenance as conceptualized by ADOPT; (b) the guiding principles used to select constructs and measures for recommendation; (c) the high-priority constructs recommended for inclusion; (d) domain-specific issues for advancing the science; and (e) recommendations for future research. SIGNIFICANCE: The inclusion of similar measures across trials will help to better identify how psychosocial factors mediate and moderate the weight loss and weight maintenance process, facilitate research into dynamic interactions with factors in the other ADOPT domains, and ultimately improve the design and delivery of effective interventions.

PMID- 29575782 TI - Accumulating Data to Optimally Predict Obesity Treatment (ADOPT) Core Measures: Behavioral Domain. AB - BACKGROUND: The ability to identify and measure behaviors that are related to weight loss and the prevention of weight regain is crucial to understanding the variability in response to obesity treatment and the development of tailored treatments. OBJECTIVES: The overarching goal of the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project is to provide obesity researchers with guidance on a set of constructs and measures that are related to weight control and that span and integrate obesity-related behavioral, biological, environmental, and psychosocial domains. This article describes how the behavioral domain subgroup identified the initial list of high-priority constructs and measures to be included, and it describes practical considerations for assessing the following four behavioral areas: eating, activity, sleep, and self-monitoring of weight. Challenges and considerations for advancing the science related to weight loss and maintenance behaviors are also discussed. SIGNIFICANCE: Assessing a set of core behavioral measures in combination with those from other ADOPT domains is critical to improve our understanding of individual variability in response to adult obesity treatment. The selection of behavioral measures is based on the current science, although there continues to be much work needed in this field. PMID- 29575784 TI - Accumulating Data to Optimally Predict Obesity Treatment (ADOPT): Recommendations from the Biological Domain. AB - BACKGROUND: The responses to behavioral, pharmacological, or surgical obesity treatments are highly individualized. The Accumulating Data to Optimally Predict obesity Treatment (ADOPT) project provides a framework for how obesity researchers, working collectively, can generate the evidence base needed to guide the development of tailored, and potentially more effective, strategies for obesity treatment. OBJECTIVES: The objective of the ADOPT biological domain subgroup is to create a list of high-priority biological measures for weight-loss studies that will advance the understanding of individual variability in response to adult obesity treatments. This list includes measures of body composition, energy homeostasis (energy intake and output), brain structure and function, and biomarkers, as well as biobanking procedures, which could feasibly be included in most, if not all, studies of obesity treatment. The recommended high-priority measures are selected to balance needs for sensitivity, specificity, and/or comprehensiveness with feasibility to achieve a commonality of usage and increase the breadth and impact of obesity research. SIGNIFICANCE: The accumulation of data on key biological factors, along with behavioral, psychosocial, and environmental factors, can generate a more precise description of the interplay and synergy among them and their impact on treatment responses, which can ultimately inform the design and delivery of effective, tailored obesity treatments. PMID- 29575785 TI - Extended-spectrum beta-lactamase-producing Escherichia coli in common vampire bats Desmodus rotundus and livestock in Peru. AB - Antibiotic resistance mediated by bacterial production of extended-spectrum beta lactamase (ESBL) is a global threat to public health. ESBL resistance is most commonly hospital-acquired; however, infections acquired outside of hospital settings have raised concerns over the role of livestock and wildlife in the zoonotic spread of ESBL-producing bacteria. Only limited data are available on the circulation of ESBL-producing bacteria in animals. Here, we report ESBL producing Escherichia coli in wild common vampire bats Desmodus rotundus and livestock near Lima, Peru. Molecular analyses revealed that most of this resistance resulted from the expression of blaCTX-M-15 genes carried by plasmids, which are disseminating worldwide in hospital settings and have also been observed in healthy children of Peru. Multilocus sequence typing showed a diverse pool of E. coli strains carrying this resistance that were not always host species-specific, suggesting sharing of strains between species or infection from a common source. This study shows widespread ESBL resistance in wild and domestic animals, supporting animal communities as a potential source of resistance. Future work is needed to elucidate the role of bats in the dissemination of antibiotic-resistant strains of public health importance and to understand the origin of the observed resistance. PMID- 29575787 TI - Sequential Coating of Insulin Secreting Beta Cells within Multilayers of Polysaccharide Nanogels. AB - Pancreatic islet transplantation has emerged as a promising treatment for type-1 diabetes (T1D); however, its clinical application is still limited by the life long use of immunosuppressive drugs, insufficient number of islets to achieve normoglycemia, and large transplantation volume. This paper reports a unique approach for nanothin coating of insulin secreting beta cell aggregates. The coating is based on hydrophobic and covalent interactions between natural acrylate modified cholesterol bearing pullulan (CHPOA) nanogels and MIN6 beta cell aggregates. Beta cell aggregates are prepared as spheroids through hanging drop method, which is optimized with respect to hanging drop volume and initial number of beta cells. These aggregates, defined as pseudoislets, are coated with sequential layers of nanogels and are evaluated as viable and functional for insulin secretion. Coating experiments are carried out using physiologically compatible medium, where pseudoislets are not brought in contact with toxic prepolymer solutions used in existing approaches. This study offers new opportunities through coating of islets with advanced functional materials under completely physiological conditions for clinical translation of cell transplantation technology. The technique developed here will establish a new paradigm for creating tolerable grafts for other chronic diseases such as anemia, cancer, central nervous system (CNS) diseases. PMID- 29575786 TI - Lactation and progression to type 2 diabetes in patients with gestational diabetes mellitus: A systematic review and meta-analysis of cohort studies. AB - AIMS/INTRODUCTION: To explore the association between lactation and type 2 diabetes incidence in women with prior gestational diabetes. MATERIALS AND METHODS: We searched PubMed, Embase and the Cochrane Library for cohort studies published through 12 June 2017 that evaluated the effect of lactation on the development of type 2 diabetes in women with prior gestational diabetes. A random effects model was used to estimate relative risks (RRs) with 95% confidence intervals (CIs). RESULTS: A total of 13 cohort studies were included in the meta analysis. The pooled result suggested that compared with no lactation, lactation was significantly associated with a lower risk of type 2 diabetes (RR 0.66, 95% CI 0.48-0.90, I2 = 72.8%, P < 0.001). This relationship was prominent in a study carried out in the USA (RR 0.66, 95% CI 0.43-0.99), regardless of study design (prospective design RR 0.56, 95% CI 0.41-0.76; retrospective design RR 0.63, 95% CI 0.40-0.99), smaller sample size (RR 0.52, 95% CI 0.30-0.92, P = 0.024) and follow-up duration >1 years (RR 0.75, 95% CI 0.56-1.00), and the study used adjusted data (RR 0.69, 95% CI 0.50-0.94). Finally, by pooling data from three studies, we failed to show that compared with no lactation, long-term lactation (>1 to 3 months postpartum) was associated with the type 2 diabetes risk (RR 0.69, 95% CI 0.41-1.17). CONCLUSIONS: The present meta-analysis showed that lactation was associated with a lower risk of type 2 diabetes in women with prior gestational diabetes. Furthermore, no significant relationship between long-term lactation and type 2 diabetes risk was detected. The impact of long-term lactation and the risk of type 2 diabetes should be verified in further large scale studies.

The present study compares the outcome of AKI in intensive care unit (ICU) patients randomized to treatment with tidal PD (TPD) or continuous venovenous hemodiafiltration (CVVHDF). One hundred and twenty-five ICU patients with AKI were randomly allotted to CVVHDF, (Group A, N = 62) or TPD, (group B, N = 63). Cause and severity of renal injury were assessed at the time of initiating dialysis. The primary outcome was hospital mortality at 28 days, and secondary outcomes were time to recovery of renal function, duration of stay in the ICU, metabolic and fluid control, and improvement of sensorial and hemodynamic parameters. No statistically significant differences were observed between groups in regard to patients' characteristics. The survival at 28 days was significantly better in the patients treated with TPD when compared to CVVHDF (69.8% vs. 46.8%, P < 0.01). Infectious complications were significantly less (P < 0.01) in the TPD group (9.5%) when compared to the CVVHDF group (17.7%). Recovery of kidney function (60.3% vs. 35.5%), median time to resolution of AKI and the median duration of ICU stay of 9 days (7-11) vs. 19 days (13-20) were all in favor of TPD (P < 0.01). This study suggests that there are better outcomes with TPD compared to CRRT in the treatment of critically ill patients with AKI.

AB - Total flavonoid content (TFC) and cyanidin-3-glucoside (Cyd-3-glu) of seed and seed coat extract of 16 genotypes from five species of Carthamus were studied, and their major polyphenolic compounds and antioxidant activity of the seed coat extracts were determined using HPLC analysis and DPPH assay, respectively. Additionally, fatty acids composition of the seed oil was analyzed by GC. In general, TFC and Cyd-3-glu content of seed coat extracts were higher than those of seed extracts. A novel breeding line with black seed coat (named A82) depicted lower TFC (3.79 mg QUE/g DW) but higher Cyd-3-glu (24.64 mg/g DW) compared to the white and other seed-pigmented genotypes. DPPH radical scavenging activity showed a strong association with Cyd-3-glu content (r = 0.84), but no correlation with TFC (r = -0.32). HPLC analysis of seed coat extracts revealed that four compounds were dominant constituents including rutin (7.23 - 117.95 mg/100 g DW), apigenin (4.37 - 64.88 mg/100 g DW), quercetin (3.09 - 14.10 mg/100 g DW), and ferulic acid (4.49 - 30.41 mg/100 g DW). Interestingly, the genotype A82 with an appropriate polyunsaturated/saturated fatty acids index (5.46%) and a moderate linoleic fatty acid content (64.70%) had higher nutritional and pharmaceutical value than all the other genotypes. PMID- 29575790 TI - Salt induction and activation of MtlD, the key enzyme in the synthesis of the compatible solute mannitol in Acinetobacter baumannii. AB - Mannitol is the major compatible solute, next to glutamate, synthesized by the opportunistic human pathogen Acinetobacter baumannii under low water activities. The key enzyme for mannitol biosynthesis, MtlD, was identified. MtlD is highly similar to the bifunctional mannitol-1-phosphate dehydrogenase/phosphatase from Acinetobacter baylyi. After deletion of the mtlD gene from A. baumannii ATCC 19606T cells no longer accumulated mannitol and growth was completely impaired at high salt. Addition of glycine betaine restored growth, demonstrating that mannitol is an important compatible solute in the human pathogen. MtlD was heterologously produced and purified. Enzyme activity was strictly salt dependent. Highest stimulation was reached at 600 mmol/L NaCl. Addition of different sodium as well as potassium salts restored activity, with highest stimulations up to 41 U/mg protein by sodium glutamate. In contrast, an increase in osmolarity by addition of sugars did not restore activity. Regulation of mannitol synthesis was also assayed at the transcriptional level. Reporter gene assays revealed that expression of mtlD is strongly dependent on high osmolarity, not discriminating between different salts or sugars. The presence of glycine betaine or its precursor choline repressed promoter activation. These data indicate a dual regulation of mannitol production in A. baumannii, at the transcriptional and the enzymatic level, depending on high osmolarity.

AB - Significantly effective therapies need to be developed for chronic nonhealing diabetic wounds. In this work, the topical transplantation of mesenchymal stem cell (MSC) seeded on an acellular dermal matrix (ADM) scaffold is proposed as a novel therapeutic strategy for diabetic cutaneous wound healing. GFP-labeled MSCs were cocultured with an ADM scaffold that was decellularized from normal mouse skin. These cultures were subsequently transplanted as a whole into the full thickness cutaneous wound site in streptozotocin-induced diabetic mice. Wounds treated with MSC-ADM demonstrated an increased percentage of wound closure. The treatment of MSC-ADM also greatly increased angiogenesis and rapidly completed the reepithelialization of newly formed skin on diabetic mice. More importantly, multiphoton microscopy was used for the intravital and dynamic monitoring of collagen type I (Col-I) fibers synthesis via second harmonic generation imaging. The synthesis of Col-I fibers during diabetic wound healing is of great significance for revealing wound repair mechanisms. In addition, the activity of GFP-labeled MSCs during wound healing was simultaneously traced via two-photon excitation fluorescence imaging. Our research offers a novel advanced nonlinear optical imaging method for monitoring the diabetic wound healing process while the ADM and MSCs interact in situ.

AB - Inflammation and metabolic disorder are common pathophysiological conditions, which play a vital role in the development of obesity and type 2 diabetes. The purpose of this study was to explore the effects of caspase recruitment domain (CARD) 9 in the high fat diet (HFD)-treated mice and attempt to find a molecular therapeutic target for obesity development and treatment. Sixteen male CARD9-/- and corresponding male WT mice were fed with normal diet or high fat diet, respectively, for 12 weeks. Glucose tolerance, insulin resistance, oxygen consumption and heat production of the mice were detected. The CARD9/MAPK pathway related gene and protein were determined in insulin-responsive organs using Western blotting and quantitative PCR. The results showed that HFD-induced insulin resistance and impairment of glucose tolerance were more severe in WT mice than that in the CARD9-/- mice. CARD9 absence significantly modified O2 consumption, CO2 production and heat production. CARD9-/- mice displayed the lower expression of p38 MAPK, JNK and ERK when compared to the WT mice in both HFD- and ND-treated groups. HFD induced the increase of p38 MAPK, JNK and ERK in WT mice but not in the CARD9-/- mice. The results indicated that CARD9 absence could be a vital protective factor in diet-induced obesity via the CARD9/MAPK pathway, which may provide new insights into the development of gene knockout to improving diet-induced obesity and metabolism disorder. PMID- 29575793 TI - Influence of beverages and surface roughness on the color change of resin composites. AB - AIM: The aim of the present study was to determine the degree of surface staining and roughness of resin composites (RC) after finishing and polishing with different methods and immersion in three soft drinks. METHODS: A microhybrid, a nanohybrid, and a hybrid composite were selected. The specimens were prepared and divided into three groups of 36 after 24 hours, and designated as either unpolished or polished using Sof-Lex discs or Enhance point. Each group was further divided into three subgroups, immersed in distilled water, coffee, or cola for 1 week (N = 12). Color change (?E) was measured by a spectrophotometer after each treatment. The ?E was calculated using the following formula: ?E = ([?L]2+[?a]2+[?b]2)1/2. Surface roughness (Ra) was measured after 24 hours and 1 week. To observe the Ra, a scanning electron microscope was used. RESULTS: A moderate correlation between Ra and ?E was determined. Only coffee caused perceptible ?E. The effect of Ra on staining was statistically significant (P < .05), but immersion in solutions for 7 days did not increase the Ra of RC. CONCLUSIONS: The highest Ra values were obtained from hybrid RC. The Enhance point created the greatest roughness. Coffee was associated with the greatest ?E for all materials and polishing methods. PMID- 29575794 TI - Morphological and Biochemical Features of Cerebellar Cortex After Exposure to Zinc Oxide Nanoparticles: Possible Protective Role of Curcumin. AB - Zinc oxide nanoparticles (ZnONPs) are widely used in the last decades. Therefore, investigation of its neurotoxic effect is important. This work aimed to investigate the potential adverse effects of ZnONPs on rat's cerebellar cortex and the possible neuroprotective role of curcumin (Cur). Forty male albino rats were randomly divided into four equal groups. Two groups were injected with ZnONPs and one group was previously received Cur before ZnONPs. At the end of the experiment, cerebellar tissue samples were prepared for histological, morphometric, immunohistochemical study, and tissue levels of oxidative stress markers and cytokine analysis. cerebellar damage is clearly visible with ZnONPs. Degeneration, loss, disorganization of cerebellar neurons was observed. Histopathological degeneration of Purkinje and granular cells together with loss of Nissl substance, astrocyte gliosis, and affection of cerebellar blood brain barrier were detected. Moreover, an apoptotic marker (caspase-3) was significantly expressed in Purkinje and granular layers together with elevated gene expression of P53 and COX-2 in cerebellar tissue of ZnONPs intoxicated group. Astrocyte gliosis and inflammatory markers IL-1, IL-6, and TNF-alpha were expressed significantly in ZnONPs intoxicated cerebellum. These changes were associated with evidence of cerebellar oxidative stress. Strikingly, treatment with Cur together with ZnONPs recorded morphological improvement, with increased number of Purkinje cells and decreased caspase +ve cells. These findings were confirmed by morphometric and statistical analysis. Cur ameliorates the deterious effect of ZnONPs on the cerebellar cortex through its antioxidant, antiapoptotic, and anti-inflammatory efficacies. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29575795 TI - Synthesis and effect of a new Terbium gibberellic complex on the histopathological alteration induced by Gibberellic acid on liver and kidney of mice Mus musculus. AB - The objective of this study was to synthesize Gibberellic lanthanide complex and evaluate its biological activity to reduce the Gibberellic acid toxicity on liver and kidney. The new bis(Gibberellic)-nitro-terbium(III) complex was characterized by different analytical methods: elemental analyses, UV-Vis, molar ratio, fluorescence, FT-IR, and TGA-DTA measurements. Thirty newborns were classified into three groups control, Gibberellic acid, and Terbium gibberellic acid complex. Livers and kidneys of studied groups proceed for general histology and immunohistochemical staining of Cyr61, cytochrome C, and TNFR2. From the absorption titration measurements, the binding constants of DNA with Tb(III) (GA)2 complex and free ligand were found to be 3.9 * 104 and 2.1 * 103 m-1 , respectively, with the stoichiometry of 1:1. Hypochromism was observed from the absorption titration experiment which indicates the intercalation of Tb(III) (GA)2 complex between the base pairs of DNA. Gibberellic acid-treated group showed alteration in the histological picture of livers and kidneys that accompanied with the reduction in the expression of Cyr61, cyt C, and TNFR2. The amelioration was observed in Gibberellic acid complex with Terbium group. The study concluded that Terbium gibberellic complex is less dangerous effects than Gibberellic acid alone.

PMID- 29575797 TI - Airway cells from protracted bacterial bronchitis and bronchiectasis share similar gene expression profiles. AB - AIM: Protracted bacterial bronchitis (PBB) is a common cause of prolonged cough in young children, and may be a precursor of bronchiectasis. Bacteria are often present in the lower airways in both PBB and bronchiectasis and may cause persistent infections. However, there is a paucity of information available on the pathogenesis of PBB and the factors associated with persistent bacterial infection and progression to bronchiectasis. This study hypothesised that lung immune cells in recurrent PBB and bronchiectasis differentially express genes related to immune cell dysfunction compared to lung immune cells from control subjects. METHOD: Cells isolated from bronchoalveolar lavage (adult-control and PBB BAL cells) were stimulated with nontypeable Haemophilus influenzae (NTHi), and expression of genes involved in various inflammatory pathways was assessed. RESULT: NTHi induced production of large amounts of IL-1beta, IL-6, and IL-8 in adult-control BAL cells, however BAL cells from PBB airways appeared refractory to NTHi stimulation. BAL cells from PBB and bronchiectasis showed differential expression of several genes relative to control cells, including CCL20, MARCO, CCL24, IL-10, PPAR-gamma, CD200R, TREM2, RelB. Expression of genes involved in resolution of inflammation and anti-inflammation response, such as CD200R and IL 10, was associated with the number of pathogenic bacteria found in the airways. CONCLUSION: In summary, we have shown that the expression of genes related to macrophage function and resolution of inflammation are similar in PBB and bronchiectasis. Lung immune cell dysfunction in PBB and bronchiectasis may contribute to poor bacterial clearance and prolonged resolution of inflammation. PMID- 29575798 TI - Structural and functional characterisation of multi-copper oxidase CueO from lignin-degrading bacterium Ochrobactrum sp. reveal its activity towards lignin model compounds and lignosulfonate. AB - : The identification of enzymes responsible for oxidation of lignin in lignin degrading bacteria is of interest for biotechnological valorization of lignin to renewable chemical products. The genome sequences of two lignin-degrading bacteria, Ochrobactrum sp., and Paenibacillus sp., contain no B-type DyP peroxidases implicated in lignin degradation in other bacteria, but contain putative multicopper oxidase genes. Multi-copper oxidase CueO from Ochrobactrum sp. was expressed and reconstituted as a recombinant laccase-like enzyme, and kinetically characterized. Ochrobactrum CueO shows activity for oxidation of beta aryl ether and biphenyl lignin dimer model compounds, generating oxidized dimeric products, and shows activity for oxidation of Ca-lignosulfonate, generating vanillic acid as a low molecular weight product. The crystal structure of Ochrobactrum CueO (OcCueO) has been determined at 1.1 A resolution (PDB: 6EVG), showing a four-coordinate mononuclear type I copper center with ligands His495, His434 and Cys490 with Met500 as an axial ligand, similar to that of Escherichia coli CueO and bacterial azurin proteins, whereas fungal laccase enzymes contain a three-coordinate type I copper metal center. A trinuclear type 2/3 copper cluster was modeled into the active site, showing similar structure to E. coli CueO and fungal laccases, and three solvent channels leading to the active site. Site directed mutagenesis was carried out on amino acid residues found in the solvent channels, indicating the importance for residues Asp102, Gly103, Arg221, Arg223, and Asp462 for catalytic activity. The work identifies a new bacterial multicopper enzyme with activity for lignin oxidation, and implicates a role for bacterial laccase-like multicopper oxidases in some lignin-degrading bacteria.

PMID- 29575800 TI - Membrane-Based SDS Depletion Ahead of Peptide and Protein Analysis by Mass Spectrometry. AB - SDS interferes with both bottom-up and top-down MS analysis, requiring removal prior to detection. Filter-aided sample preparation (FASP) is favored for bottom up proteomics (BUP) while acetone precipitation is popular for top-down proteomics (TDP). We recently demonstrated acetone precipitation in a membrane filter cartridge. Alternatively, our automated electrophoretic device, termed transmembrane electrophoresis (TME), depletes SDS for both TDP and BUP studies. Here TME is compared to these two alternative methods of SDS depletion in both BUP and TDP workflows. To do so, a modified FASP method is described applicable to the SDS purification and recovery of intact proteins, suitable for LC/MS. All three methods reliably deplete >99.8% SDS. TME provide higher sample yields (average 90%) than FASP (55%) or acetone precipitation (57%), translating into higher total protein identifications (973 vs 877 FASP or 890 acetone) and higher spectral matches (2.5 times) per protein. In a top down workflow, each SDS depletion method yields high-quality MS spectra for intact proteins. These results show each of these membrane-based strategies is capable of depleting SDS with high sample recovery and high spectra quality for both BUP and TDP studies. PMID- 29575801 TI - Drug abuse screening with exhaled breath and oral fluid in adults with substance use disorder. AB - In the treatment of substance use disorder, regular laboratory-based testing has the dual purpose of monitoring compliance with the prescribed medication and abstention from medically non-motivated substances (ie, drug abuse screening). The principal specimen for testing is urine, but collection of urine has some disadvantages, for example being more time-consuming and more intrusive compared to other matrices. There is also the risk of adulteration. This project compared exhaled breath and oral fluid as alternative matrices for drug abuse screening in patients with substance use disorder. All 51 subjects included in the study were enrolled at the Drug Addiction Emergency Unit in Stockholm. Exhaled breath, oral fluid, and urine samples were collected together with a self-report. Of all 117 self-reported drug intakes during the previous week, 72% were confirmed in urine, 73% in oral fluid and 39% in exhaled breath. In 31% of the subjects, additional substances other than those self-reported were detected analytically. For substance abuse screening, urine had the highest detection rate for buprenorphine, cannabis, and benzodiazepines, while oral fluid had the highest detection rate for amphetamines and methadone. Exhaled breath showed the highest detection rate of all matrices for cocaine. To identify significant differences in detection rates between the matrices future studies with larger sampling sizes are needed. Both oral fluid and exhaled breath are viable alternative specimens to urine, depending on the circumstances and purpose of the testing.

PMID- 29575803 TI - Sustained Response Following Discontinuation of Methotrexate in Patients With Rheumatoid Arthritis Treated With Subcutaneous Tocilizumab: Results From a Randomized, Controlled Trial. AB - OBJECTIVE: To evaluate whether tocilizumab (TCZ) monotherapy is noninferior to treatment with TCZ plus methotrexate (MTX) for maintaining clinical responses in patients with rheumatoid arthritis (RA) in whom low disease activity is achieved with TCZ plus MTX. METHODS: Patients with RA who experienced an inadequate response to MTX received MTX plus TCZ 162 mg subcutaneously. At 24 weeks, patients who achieved a Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR) of <=3.2 were randomized to receive TCZ monotherapy or to continue treatment with TCZ plus MTX until week 52. The primary outcome measure was the comparison of the mean change in the DAS28-ESR from week 24 to week 40 between the TCZ monotherapy and TCZ plus MTX arms (noninferiority margin of 0.6). Secondary outcome measures included worsening of the DAS28-ESR by >=1.2, achievement of a DAS28-ESR of <2.6 and <=3.2, and safety and immunogenicity. RESULTS: Among the 718 patients enrolled, 296 were randomized at week 24 to receive TCZ monotherapy (n = 147) or TCZ plus MTX (n = 147). The mean changes in the DAS28-ESR from week 24 to week 40 were 0.46 and 0.14 in the TCZ monotherapy arm and the TCZ plus MTX arm, respectively (weighted difference between the groups, 0.318 [95% confidence interval 0.045, 0.592]); discontinuing MTX in TCZ responders was noninferior to continuing MTX. Safety events were broadly similar between the randomized treatment groups; the most common serious adverse event was infection, which occurred in 2.1% of patients in the TCZ monotherapy group and 2.2% of patients receiving TCZ plus MTX. CONCLUSION: Patients with RA receiving TCZ plus MTX who achieve low disease activity can discontinue MTX without significant worsening of disease activity during the 16 weeks following MTX discontinuation. PMID- 29575804 TI - Clinical and functional correlates of financially deprived women with first episode psychosis. AB - BACKGROUND: Women, especially those with low-socio-economic status and financial deprivation, are found to be affected by mental illnesses disproportionately. We compared the clinical, functioning and cognitive characteristics between the financially deprived women with first-episode psychosis and their non-deprived women counterparts. METHOD: A cross-sectional analysis of consecutively recruited first-episode psychosis women patients was conducted. A total of 93 financially deprived women patients and 105 non-deprived women patients aged 25 to 55 years were compared in terms of demographic, premorbid and help-seeking characteristics, baseline clinical characteristics, baseline functioning and baseline cognitive functioning. RESULTS: Financially deprived women were older (P = .005), had received less education (P = .001), more likely to live alone (P < .001) and with a higher proportion of immigrants (P = .001). Whereas there was no significant difference found in duration of untreated psychosis, deprived women had more severe depressive symptoms (P = .021) and more severe negative symptoms, in terms of avolition-apathy (P = .003) and anhedonia-asociality (P = .008). They also perform worse in social and occupational functioning (P = .002) and a range of cognitive abilities. CONCLUSIONS: Nearly half of the adult female patients with first-episode psychosis in Hong Kong encountered persistent financially difficulties. The fact that they suffer from more severe symptoms and worsened functioning and cognitive abilities at an early stage of illness shows that this subgroup of patients warrant assistance and attention. PMID- 29575805 TI - Optic disc-fovea distance and myopia progression in school children: the Beijing Children Eye Study. AB - PURPOSE: To assess changes in the optic disc-fovea distance (DFD) with progressing myopia in school children. METHODS: The school-based, prospective, longitudinal study included grade-1 children in 2011 who were yearly re-examined until 2016. We measured DFD, optic disc diameters and width of parapapillary gamma zone (parapapillary region without Bruch's membrane (BM)) on fundus photographs. RESULTS: Of 382 grade-1 children examined in 2011, 294 (77.0%) children (mean age in 2011: 6.4 +/- 0.5 years) returned to be examined in 2016. In relative terms, the increase in DFD (1.15 +/- 0.33 mm) was more due to an increase in gamma zone width (+300% or 0.29 +/- 0.30 mm) than an increase in macular BM length (+18% or 0.74 +/- 0.21 mm). In multivariate regression analysis, longer increase in DFD was correlated (regression coefficient r2 = 0.79) with longer axial elongation during the study period (p < 0.001; standardized regression coefficient beta: 0.61; non-standardized regression coefficient B: 0.30; 95% confidence interval (CI): 0.26, 0.33), larger increase in gamma zone width (p < 0.001; beta: 0.35; B: 0.40; 95%CI: 0.32, 0.48) and longer axial length in 2011 (p = 0.01; beta:0.07; B:0.03; 95%CI:0.01, 0.06). Larger increase in gamma zone width was associated (r2 = 0.73) with larger increase in DFD (p < 0.001; beta: 0.51; B: 0.46; 95%CI: 0.39, 0.53), larger increase in the vertical-to-horizontal disc diameter ratio (p < 0.001; beta: 0.43; B:1.21; 95%CI: 1.00, 1.42) and longer vertical disc diameter (p < 0.001; beta: 0.15; B:0.24; 95%CI: 0.14, 0.34). CONCLUSION: In adolescent school children, axial elongation-associated increase in DFD was mainly due to an enlargement (+300%) of parapapillary gamma zone, while macular BM length increased to minor degree (+18%). Gamma zone enlargement was correlated with axial elongation-associated vertical optic disc rotation, potentially due to an increased backward pull of the optic nerve on the temporal optic disc border. PMID- 29575806 TI - Success and failure in replication of genotype-phenotype associations: How does replication help in understanding the genetic basis of phenotypic variation in outbred populations? AB - Recent developments in sequencing technologies have facilitated genomewide mapping of phenotypic variation in natural populations. Such mapping efforts face a number of challenges potentially leading to low reproducibility. However, reproducible research forms the basis of scientific progress. We here discuss the options for replication and the reasons for potential nonreproducibility. We then review the evidence for reproducible quantitative trait loci (QTL) with a focus on natural animal populations. Existing case studies of replication fall into three categories: (i) traits that have been mapped to major effect loci (including chromosomal inversion and supergenes) by independent research teams; (ii) QTL fine-mapped in discovery populations; and (iii) attempts to replicate QTL across multiple populations. Major effect loci, in particular those associated with inversions, have been successfully replicated in several cases within and across populations. Beyond such major effect variants, replication has been more successful within than across populations, suggesting that QTL discovered in natural populations may often be population-specific. This suggests that biological causes (differences in linkage patterns, allele frequencies or context-dependencies of QTL) contribute to nonreproducibility. Evidence from other fields, notably animal breeding and QTL mapping in humans, suggests that a significant fraction of QTL is indeed reproducible in direction and magnitude at least within populations. However, there is also a large number of QTL that cannot be easily reproduced. We put forward that more studies should explicitly address the causes and context-dependencies of QTL signals, in particular to disentangle linkage differences, allele frequency differences and gene-by environment interactions as biological causes of nonreproducibility of QTL, especially between populations. PMID- 29575807 TI - 3-Aminomethyl pyridine chalcone derivatives: Design, synthesis, DNA binding and cytotoxic studies. AB - Herein we report design, synthesis, and anticancer activity of compounds 6a-h and 11a-j. Compounds 6a-f were designed based on 3-aminomethyl pyridine attached to different acetamide derivatives and in compounds 6g-h it was attached to coumarin moiety. Coumarin containing compounds 6g-h showed very poor anticancer activity against both A549 (Lungs cancer cell line), and MCF-7 (Breast cancer cell line) cell lines in MTT assay. Compounds 11a-j were designed as derivatives of 3 aminomethyl pyridine and 4-amino chalcones. A series of chalcone derivatives of 3 aminomethyl pyridine 11a-j have been synthesized and screened for their in vitro anticancer activity and DNA binding affinity. Most of the compounds showed very good antimitotic activity against A549 cell line as compared to fluorouracil. Compounds 11g and 11i were selected for DNA-binding studies as they showed excellent activity against cancer cell lines in MTT assay. CT-DNA binding affinity of compounds 11g and 11i have been investigated by UV based DNA titration and fluorescence emission study against DNA-EtBr complex. Interestingly, compound 11i has displayed excellent antiproliferative activity, with IC50 0.0067 +/- 0.0002 MUm, against MCF-7 cell line. Compound 11i has been studied for its cytotoxicity using MTT, LDH, as well as EtBr/AO assay and was found to induce apoptosis in the cancerous cell line. PMID- 29575808 TI - Intraoperative difficulties, complications and self-assessed visual function in cataract surgery. AB - PURPOSE: To study associations between intraoperative difficulties and changes in patient-perceived and postoperative visual function and visual satisfaction after cataract surgery. METHODS: Swedish multicenter, prospective, cross-sectional, nonrandomized, National Cataract Register study. A total of 10 979 patients (n = 10 979) who underwent cataract surgery from 2008 to 2011 completed the Catquest 9SF questionnaire before and 3 months postoperatively. Using Rasch analysis, we converted the nonparametric grading of the answers to parametric data and performed parametric statistical analyses. Multiple regression models were used to examine possible predictors associated with self-assessed visual function after cataract surgery. RESULTS: Greater improvement in self-assessed visual function was seen in patients in whom trypan blue dye was used; those without a posterior capsular tear or an ocular comorbidity; and those who were younger, female and had low preoperative corrected distance visual acuity (CDVA) or high postoperative CDVA compared with their counterparts. Significantly higher self assessed postoperative visual function was seen in patients in whom trypan blue dye was used and those with no posterior capsular tear or ocular comorbidity and no use of capsular hooks; and those who were younger and had low preoperative or high postoperative CDVA compared with their counterparts. The risk of general dissatisfaction after cataract surgery was significantly greater in patients with a posterior capsule tear, ocular comorbidity or low postoperative CDVA, and those in whom mechanical pupillary stretching was performed. CONCLUSION: Several intraoperative difficulties, posterior capsular tear, ocular comorbidity, age, gender, and preoperative and postoperative CDVAs affect patient improvement and self-assessed visual function after cataract surgery.

PMID- 29575809 TI - IL-37 inhibits invasion and metastasis in non-small cell lung cancer by suppressing the IL-6/STAT3 signaling pathway. AB - BACKGROUND: IL-37 has been identified as a fundamental inhibitor of inflammatory and immunity responses. It plays a crucial protective role in several cancers, but its anti-tumor activity and the potential regulatory mechanism of IL-37 in non-small cell lung cancer (NSCLC) is largely unclear. METHODS: Enzyme-linked immunosorbent assay was used to detect plasma IL-37 expression in NSCLC patients and healthy controls. The NSCLC cell line A549 was cultured with recombinant human IL-37 or recombinant human IL-6 protein. A549 invasion and metastasis were detected using Transwell invasion and scratch wound healing assays, respectively. Protein expression of STAT3, pSTAT3, E-cadherin, vimentin, and N-cadherin were detected using Western blotting, and messenger RNA expression of STAT3, E cadherin, vimentin, and N-cadherin was assessed in each group using real time PCR. RESULTS: IL-37 plasma expression was decreased in NSCLC patients, and the downregulation of IL-37 was correlated with tumor stage. In vitro, IL-37 inhibited invasion and migration in A549 cells, while IL-6 promoted invasion and migration in A549 cells. pSTAT3, vimentin, and N-cadherin expression was increased. E-cadherin expression was lower in the IL-6 group than in the control group; however, the opposite pattern was observed in the IL-37 + IL-6 group. CONCLUSION: Our results showed that IL-37 plays an inhibitory role in NSCLC progression, possibly by suppressing STAT3 activation and decreasing epithelial to-mesenchymal transition by inhibiting IL-6 expression. IL-37 could serve as a potential novel tumor suppressor in NSCLC.

AB - Selenadiazole derivatives (SeDs) have been found to show promise in chemo /radiotherapy applications by activating various downstream signaling pathways. However, the functional role of SeDs on angiogenesis, which is pivotal for tumor progression and metastasis, has not yet been elucidated. In the present study, we have examined the antiangiogenic activities of SeDs and elucidated their underlying mechanisms. The results showed that the as-synthesized SeDs not only enhanced their anticancer activities against several human cancer cells but also showed more potent inhibition on human umbilical vein endothelial cells (HUVECs). The in vitro results suggested that SeDs, especially 1 a, dose-dependently inhibited the vascular endothelial growth factor (VEGF)-induced cell migration, invasion, and capillary-like structure formation of HUVECs. Compound 1 a also significantly suppressed VEGF-induced angiogenesis in a Matrigel plug assay as part of a C57/BL6 mice assay by means of down regulation of VEGF. Furthermore, we found that 1 a significantly inhibited MCF-7 human breast tumor growth in nude mice without severe systematic cytotoxicity. Compound 1 a was more effective in inhibiting cell proliferation and induced a much more pronounced apoptosis effect in endothelial cells than MCF-7 cells, which implies that endothelial cells might be the primary target of 1 a. Further mechanistic studies on tumor growth inhibition effects and neovessel formation suppression demonstrated that 1 a inhibited cell viability of MCF-7 and HUVECs by induction of cell apoptosis, accompanied by poly(adenosine diphosphate ribose)polymerase (PARP) cleavage and caspase activation. Additionally, the 1 a-induced antiangiogenesis effect was achieved by abolishing the VEGF-VEGFR2-ERK/AKT (ERK=extracellular signal regulated kinases; AKT=protein kinease B) signal axis and enhanced the apoptosis effect by triggering reactive oxygen species (ROS)-mediated DNA damage. Taken together, these results clearly demonstrate the antiangiogenic potency of SeDs and the underlying molecular mechanisms.

AB - All-inorganic CsPbX3 (X=I, Br) perovskite solar cells are regarded as cost effective and stable alternatives for next-generation photovoltaics. However, sluggish charge extraction at CsPbX3 /charge-transporting material interfaces, which arises from large interfacial energy differences, have markedly limited the further enhancement of solar cell performance. In this work, the work function (WF) of the back electrode is tuned by doping alloyed PtNi nanowires in carbon ink to promote hole extraction from CsPbBr3 halides, while an intermediate energy by setting carbon quantum dots (CQDs) at TiO2 /CsPbBr3 interface bridges electron transportation. The preliminary results demonstrate that the matching WFs and intermediate energy level markedly reduce charge recombination. A power conversion efficiency of 7.17 % is achieved for the WF-tuned all-inorganic perovskite solar cell, in comparison with 6.10 % for the pristine device, and this is further increased to 7.86 % by simultaneously modifying with CQDs. The high efficiency and improved stability make WF-controlled all-inorganic perovskite solar cells promising to develop advanced photovoltaic platforms. PMID- 29575812 TI - Branched Chain Amino Acids, Androgen Hormones, and Metabolic Risk Across Early Adolescence: A Prospective Study in Project Viva. AB - OBJECTIVE: This study aimed to examine the associations of two obesity-related metabolite patterns with changes in metabolic biomarkers during early adolescence. METHODS: Multivariable linear regression was used to examine associations of branched chain amino acid (BCAA) and androgen hormone patterns with changes in glycemia (fasting glucose, insulin, homeostatic model assessment of insulin resistance), adipokines (leptin, adiponectin), inflammation (C reactive protein, interleukin-6), lipid profile, and blood pressure during ~5 years of follow-up among 213 children aged 6 to 10 years at baseline. Covariates included baseline age, pubertal status, biomarker level, and BMI percentile, and age at follow-up. Interactions with sex and baseline BMI percentile were also considered. RESULTS: The median age at baseline was 7.7 years; 48.8% were boys. In adjusted models, each 1 unit of the BCAA pattern corresponded with a 4.82 (95% CI: 0.92 to 8.71) mg/dL decrease in fasting glucose in boys. In girls, the BCAA pattern was associated with an increase in triglycerides (4.17 [0.03 to 8.32] mg/dL). The androgen pattern was associated with decreased leptin (-2.35 [-4.34 to -0.35] ng/dL) and increased C-reactive protein (0.28 [0.03 to 0.54] mg/dL) in girls. These relationships did not differ by baseline BMI percentile. CONCLUSIONS: The BCAA and androgen hormone metabolite patterns are related to changes in metabolic parameters in a sex-specific manner during early adolescence. PMID- 29575814 TI - Seed phytochemicals shape the community structures of cultivable actinobacteria inhabiting plant interiors of Thai pigmented rice. AB - We examined abundance, bioactivity, and endophytism of cultivable actinobacteria isolated from plant interiors of two Thai pigmented rice cultivars: Hom Nin (HN) rice and Luem Pua (LP) glutinous rice. Both rice cultivars housed the same amount of endophytic actinobacteria (33 isolates each). Microbispora (76%) and Streptomyces (73%) were the predominant endophytic actinobacteria of LP glutinous rice and HN rice, respectively. Sphaerisporangium (9%) was found only in LP glutinous rice. Twelve percent of endophytic actinobacteria was the possibility of discovering novel species from both rice cultivars. Most endophytic actinobacteria exhibited plant growth-promoting potentials, including antimicrobial activity against test bacteria and phytopathogenic fungi, solubilization of phosphate, and production of biostimulants (i.e., ammonia, indole-3-acetic acid, and siderophore) and biocatalysts (i.e., amylase, cellulase, chitinase, lipase, and protease). Our findings revealed that seed phytochemicals of pigmented rice (e.g., anthocyanin, gamma-oryzanol, phytate, antioxidants, and content of amylose) were effectors, shaping the community structures and biofunctions of endophytic actinobacteria. We conclude that pigmented rice is yet a challenging source for discovery of bioactive and novel actinobacteria. This study also provides new insights into the plant-endophyte interactions by which seed phytochemicals act as a primary checkpoint in the natural selection for establishing unique plant endophytomes. PMID- 29575815 TI - Impact of age at menarche on obesity and glycemic control in Japanese patients with type 2 diabetes: Fukuoka Diabetes Registry. AB - AIMS/INTRODUCTION: A younger age at menarche is associated with obesity and type 2 diabetes in adult life. The impact of early-onset menarche on obesity and glycemic control in type 2 diabetes has not been investigated. The present study examined the relationship between age at menarche and obesity and glycemic control in type 2 diabetes. MATERIALS AND METHODS: A total of 2,133 patients with type 2 diabetes aged >=20 years were divided into groups according to age at menarche (<=11, 12, 13, 14 and >=15 years). A retrospective cohort study examined the association of menarcheal age with adiposity and hemoglobin A1c . RESULTS: Age at menarche was inversely associated with body mass index (BMI) and abdominal circumference (P < 0.001). Each 1-year decrease in age at menarche was associated with a 0.25-kg/m2 and 0.6-cm increase in BMI and abdominal circumference, respectively, using a multivariate-adjusted model. Odds ratios for obesity and abdominal obesity significantly increased in participants with age at menarche <=11 years after multivariable adjustments when age at menarche of 13 years was used as the reference (odds ratio 1.95, 95% CI 1.33-2.88, odds ratio 1.95, 95% CI 1.32-2.87, respectively). Younger age at menarche was significantly associated with higher hemoglobin A1c (P < 0.001); however, the association was not statistically significant after adjusting for BMI. CONCLUSIONS: Age at menarche of <=11 years was associated with obesity after adjusting for confounding factors, and poor glycemic control associated with high BMI in type 2 diabetes. Age at menarche should be considered during clinical assessments. PMID- 29575817 TI - Postfolate spina bifida lesion level change. AB - BACKGROUND: Spina bifida accounts for a large proportion of birth defects in the United States. Studies have evaluated the decrease in prevalence at birth after folate fortification of food grains, but little is known about neurologic functional changes related to fortification. This study assesses the functional level of lesions in the prefortification and postfortification eras. METHODS: Data were collected through retrospective review of medical records from a regional multispecialty clinic in Arizona. This study included individuals born between 1981-1995 (prefortification) and 1999-2013 (postfortification). Patients were included if they had a primary diagnosis of spina bifida with or without hydrocephalus. RESULTS: There was a significant difference in functional lesion level with an 85% reduction in thoracic level lesions in the postfortification era (p < .005). There were no differences in gender or ethnicity across eras; however, Hispanic ethnicity had a higher number of cases overall (51.7%). The most common lesion level in both eras was mid-lumbar, accounting for 35.7 and 34.4% of cases in the prefolate and postfolate eras, respectively. CONCLUSIONS: This study demonstrates a significant difference in the distribution of lesion level of spina bifida patients born in the postfortification era, based on neurologic function. Further research with a larger sample size is needed to determine if this observation holds true nationally. PMID- 29575816 TI - Kidney-Derived c-Kit+ Cells Possess Regenerative Potential. AB - Kidney-derived c-Kit+ cells exhibit progenitor/stem cell properties in vitro (self-renewal capacity, clonogenicity, and multipotentiality). These cells can regenerate epithelial tubular cells following ischemia-reperfusion injury and accelerate foot processes effacement reversal in a model of acute proteinuria in rats. Several mechanisms are involved in kidney regeneration by kidney-derived c Kit+ cells, including cell engraftment and differentiation into renal-like structures, such as tubules, vessels, and podocytes. Moreover, paracrine mechanisms could also account for kidney regeneration, either by stimulating proliferation of surviving cells or modulating autophagy and podocyte cytoskeleton rearrangement through mTOR-Raptor and -Rictor signaling, which ultimately lead to morphological and functional improvement. To gain insights into the functional properties of c-Kit+ cells during kidney development, homeostasis, and disease, studies on lineage tracing using transgenic mice will unveil their fate. The results obtained from these studies will set the basis for establishing further investigation on the therapeutic potential of c-Kit+ cells for treatment of kidney disease in preclinical and clinical studies.

AB - BACKGROUND: Rheumatoid arthritis is characterized by chronic polyarticular synovitis and presents systemic changes that impact quality of life, such as impaired muscle function, seen in up to 66% of the patients. This can progress to severely debilitating state known as rheumatoid cachexia-without loss of fat mass and body weight-for which there is little consensus in terms of diagnosis or treatment. This study aims to evaluate whether the collagen-induced arthritis (CIA) animal model also develops clinical and functional features characteristic of rheumatoid cachexia. METHODS: Male DBA1/J mice were randomly divided into 2 groups: healthy animals (CO, n = 11) and CIA animals (n = 13). The clinical score and edema size, animal weight and food intake, free exploratory locomotion, grip strength, and endurance exercise performance were tested 0, 18, 35, 45, 55, and 65 days after disease induction. After euthanasia, several organs, visceral and brown fat, and muscles were dissected and weighed. Muscles were used to assess myofiber diameter. Ankle joint was used to assess arthritis severity by histological score. Statistical analysis were performed using one-way and two-way analyses of variance followed by Tukey's and Bonferroni's test or t-test of Pearson and statistical difference were assumed for a P value under 0.05. RESULTS: The CIA had significantly higher arthritis scores and larger hind paw edema volumes than CO. The CIA had decreased endurance exercise performance total time (fatigue; 23, 22, 24, and 21% at 35, 45, 55, and 65 days, respectively), grip strength (27, 55, 63, 60, and 66% at 25, 35, 45, 55, and 65 days, respectively), free locomotion (43, 57, 59, and 66% at 35, 45, 55, and 65 days, respectively), and tibialis anterior and gastrocnemius muscle weight (25 and 24%, respectively) compared with CO. Sarcoplasmic ratios were also reduced in CIA (TA: 23 and GA: 22% less sarcoplasmic ratio), confirming the atrophy of skeletal muscle mass in these animals than in CO. Myofiber diameter was also reduced 45% in TA and 41% in GA in CIA when compared with the CO. Visceral and brown fat were lighter in CIA (54 and 39%, respectively) than CO group. CONCLUSIONS: The CIA model is a valid experimental model for rheumatoid cachexia given that the clinical changes observed were similar to those described in patients with rheumatoid arthritis. PMID- 29575820 TI - Laser imaging polarimetry of nacre. AB - Nacre is a complex biomaterial made of aragonite-tablet bricks and organic mortar that is considerably resilient against breakage. Nacre has been studied with a wide range of laboratory techniques, leading to understanding key fundamentals and informing the creation of bio-inspired materials. In this article, we present an optical polarimetric technique to investigate nacre, taking advantage of the translucence and birefringence of its microcomponents. We focus our study on 3 classes of mollusks that have nacreous shells: bivalve (Pinctada fucata), gastropod (Haliotis asinina and Haliotis rufescens) and cephalopod (Nautilus pompilius). We sent polarized light from a laser through thin samples of nacre and did imaging polarimetry of the transmitted light. We observed clear distinctions between the structures of bivalve and gastropod, due to the spatial variation of their birefringence. The patterns for cephalopod were more similar to bivalve than gastropod. Bleaching of the samples disrupted the transmitted light. Subsequent refilling of the bivalve and gastropod nacre samples with oil produced optical patterns similar to those of unbleached samples. In cephalopod samples, we found that bleaching produced irreversible changes in the optical pattern. PMID- 29575819 TI - PIK3CA mutations and their response to neoadjuvant treatment in early breast cancer: A systematic review and meta-analysis. AB - BACKGROUND: PIK3CA mutations frequently occur in breast cancer patients. This study was conducted to evaluate the relationship between PIK3CA mutations and neoadjuvant treatment response and to analyze the clinical implications. METHODS: PubMed, Embase, and the Cochrane database were searched for relevant studies in September 2017. The pooled risk ratio (RR) was estimated using fixed effects or random effects models according to heterogeneity among studies. RESULTS: This meta-analysis included 20 studies with 4392 patients. The pooled RR showed that PIK3CA mutation is correlated to lower pathological complete response (pCR) in unselected HER2+ patients (RR = 0.73; 95% confidence interval [CI] 0.66-0.81), thus the predictive value of PIK3CA status may be stronger in HER2+/HR+ patients (RR = 0.50; 95% CI 0.27-0.93) and those administered dual-targeting treatment (RR = 0.55; 95% CI 0.39-0.78). In contrast with wild type, either exon 9 (RR = 0.55; 95% CI 0.39-0.78) or exon 20 (RR = 0.71; 95% CI 0.58-0.89) mutations were significantly associated with lower pCR. The predictive value of exon 9 mutations was not significantly greater than exon 20 mutations (RR = 0.76; 95% CI 0.51 1.13). CONCLUSION: In early breast cancer, PIK3CA mutations seem to identify HER2+ patients who are less likely to reach pCR. The clinical implications of PIK3CA mutations tend to vary between exon 9 and exon 20. This mechanism should be explored in further studies. PMID- 29575821 TI - Peripheral retinal changes in highly myopic young Asian eyes. AB - PURPOSE: To determine the type and prevalence of peripheral retinal changes and its relationship with axial length (AL) in a population of young Asian adult males. METHODS: This was a cross-sectional study of male subjects aged between 19 and 25 years old. High myopes [spherical equivalent refraction, (SER) < -6.00 D] were recruited and underwent further ocular investigations including dilated retinal photography and binocular indirect ophthalmoscopy by two trained ophthalmologists. The frequency of peripheral retinal changes within high myopes was correlated with axial length and also compared with a group of emmetropes (SER between -0.50 D and +1.00 D). RESULTS: A total of 593 high myopes and 156 emmetropes were recruited. White without pressure (WWOP; n = 458, 46.5%) and lattice degeneration (LD; n = 109, 14.6%) were the commonest findings, and their prevalence was significantly higher among high myopes (LD, 16.9% versus 5.8%; WWOP, 57.2% versus 5.8%; both p < 0.001). Among high myopes, temporal LD was more common (71%) and 35% had more than one area in the same eye. Increasing AL was associated with LD (odds ratio 1.28, p = 0.01) and retinal holes (odd's ratio 1.44, p = 0.02) on multivariate analysis. CONCLUSION: White without pressure (WWOP) and LD were the commonest peripheral retinal changes. One-third of high myopes with LD had more than one area in the same eye. Increasing AL was associated with LD and retinal holes. Studies in older adults should be conducted to develop clinical guidelines for the management of high myopes. PMID- 29575822 TI - Antimicrobial activity of selected essential oils against Streptococcus suis isolated from pigs. AB - The inhibitory potential by contact and vapor of basil, cinnamon, clove, peppermint, oregano, rosemary, common thyme, and red thyme essential oils (EOs) against 20 strains of Streptococcus suis was determined by the disk diffusion test. The broth microdilution method was used to determine the minimal inhibitory and minimal bactericidal concentration (MIC and MBC) of the four selected oils. Furthermore, the bactericidal power (ratio MBC/MIC) was calculated. The EOs with the major potential in the disk diffusion method were red thyme, common thyme, oregano, and cinnamon (? mean 16.5-34.2 mm), whereas cinnamon did not show vapor activity. In the microdilution test, all the EOs showed notable antimicrobial activity (MIC90 and MBC90 312.5-625 MUg.ml-1 ) and a strong bactericidal power (ratio = 1). This is the first study that selects essential oils against S. suis. New studies about the possible synergic effect of EOs with antibiotics and about toxicity and efficacy in in vivo conditions are recommended. PMID- 29575823 TI - Directing-Group-mediated C-H-Alkynylations. AB - C-C triple bonds are amongst the most versatile functional groups in synthetic chemistry. Complementary to the Sonogashira coupling the direct metal-catalyzed alkynylation of C-H bonds has emerged as a highly promising approach in recent years. To guarantee a high regioselectivity suitable directing groups (DGs) are necessary to guide the transition metal (TM) into the right place. In this Focus Review we present the current developments in DG-mediated C(sp2 )-H and C(sp3 )-H modifications with terminal alkynes under oxidative conditions and with electrophilic alkynylation reagents. We will discuss further modifications of the alkyne, in particular subsequent cyclizations to carbo- and heterocycles and modifications of the DG in the presence of the alkyne. PMID- 29575824 TI - Complex Bayesian Modeling Workflows Encoding and Execution Made Easy With a Novel WinBUGS Plugin of the Drug Disease Model Resources Interoperability Framework. AB - The Drug Disease Model Resources (DDMoRe) Interoperability Framework (IOF) enables pharmacometric model encoding and execution via Model Description Language (MDL) and R language, through the ddmore package. Through its components and converter plugins, the IOF can execute pharmacometric tasks using different target tools, starting from a single MDL-encoded model. In this article, we present the WinBUGS plugin and show how its integration in the IOF enables an easy implementation of complex Bayesian workflows. We selected a published diabetes-linked study as a real-world example, in which two inter-related models are used to estimate insulin secretion rate in response to a glucose stimulus from intravenous glucose tolerance test (IVGTT) data. This model was implemented following different approaches to propagate uncertainty, via diverse IOF target tools (NONMEM, WinBUGS, PsN, and Xpose). The developed software supports a plethora of pharmacokinetic/pharmacodynamic (PK/PD) modeling features. It provides solutions to reproducibility and interoperability issues in Bayesian modeling, and facilitates the difficult encoding of complex PK/PD models in WinBUGS. PMID- 29575825 TI - Effect of lactulose intervention on gut microbiota and short chain fatty acid composition of C57BL/6J mice. AB - Gut microbiota have strong connections with health. Lactulose has been shown to regulate gut microbiota and benefit host health. In this study, the effect of short-term (3 week) intervention of lactulose on gut microbiota was investigated. Gut microbiota were detected from mouse feces by 16S rRNA high-throughput sequencing, and short chain fatty acids (SCFAs) were detected by gas chromatography-mass spectrometry (GC-MS). Lactulose intervention enhanced the alpha-diversity of the gut microbiota; increased the abundance of hydrogen producing bacteria Prevotellaceae and Rikenellaceae, probiotics Bifidobacteriaceae and Lactobacillaceae, and mucin-degrading bacteria Akkermansia and Helicobacter; decreased the abundance of harmful bacteria Desulfovibrionaceae and branched-chain SCFAs (BCFAs). These results suggest that lactulose intervention effectively increased the diversity and improved the structure of the intestinal microbiota, which may be beneficial for host health. PMID- 29575827 TI - Upcoming events of interest. PMID- 29575826 TI - Paraganglioma: Cytomorphologic features, radiologic and clinical findings in 12 cases. AB - BACKGROUND: The cytologic diagnosis of paraganglioma can be challenging because of its rarity, wide anatomic distribution, and variable cytomorphological features. DESIGN: The Johns Hopkins Hospital pathology archives were searched for fine-needle aspiration (FNA) specimens confirmed as paraganglioma on histology (2003-2015). RESULTS: Twelve specimens from 10 patients (6 males and 4 females) with an age range of 16-81 years (mean = 47) were included. Anatomic location included neck (n = 4), paraspinal (n = 2), retroperitoneum (n = 2), and peripancreatic (n = 2). Cellularity of cytological specimens ranged from scant to hypercellular. The cells were arranged in clusters (n = 7), single cells (n = 6), acini (n = 3), and syncytium (n = 1). Plasmacytoid (n = 5) and spindled cells (n = 6) were often present. Nuclear details included anisonucleosis (n = 8), marked pleomorphism (n = 8), scattered binucleation and/or multinucleation, nuclear knobbing (n = 2), speckled (n = 3), coarse (n = 2), hyperchromatic chromatin (n = 3), nuclear grooves (n = 6), intranuclear pseudoinclusions (n = 2), prominent nucleoli (n = 1), naked nuclei (n = 7), and rare nuclear streaking artifact (n = 2). Cytoplasm was delicate, abundant, and granular (n = 9). Necrosis (n = 1) was rare. Synaptophysin, chromogranin, CD56, and S100 (only in sustentacular cells) were positive in tested cases. Three cases showed loss of Succinate Dehydrogenase Subunit B (SDHB). Two patients developed metachronous lesions at different sites. Three patients developed recurrence at the surgical site. Metastatic paraganglioma to the lymph nodes (n = 2), bone (n = 1), and lung (n = 1) also occurred. CONCLUSION: An accurate diagnosis of paraganglioma on FNA specimens is crucial for proper treatment. SDH status should be considered for all patients with paraganglioma as it may be important for patients' lifelong follow-up as well as for familial considerations. Paraganglioma is a rare entity with wide age and anatomic distribution and variable cytomorphological features that often overlap with those of malignant neoplasms. Possible aggressive behavior such as recurrence and metastasis to lymph nodes, bone, and lung as well as Succinate Dehydrogenase complex mutations warrant an accurate diagnosis on aspirated material for appropriate clinical management.

PMID- 29575829 TI - Optical coherence tomography retinal image reconstruction via nonlocal weighted sparse representation. AB - We present a nonlocal weighted sparse representation (NWSR) method for reconstruction of retinal optical coherence tomography (OCT) images. To reconstruct a high signal-to-noise ratio and high-resolution OCT images, utilization of efficient denoising and interpolation algorithms are necessary, especially when the original data were subsampled during acquisition. However, the OCT images suffer from the presence of a high level of noise, which makes the estimation of sparse representations a difficult task. Thus, the proposed NWSR method merges sparse representations of multiple similar noisy and denoised patches to better estimate a sparse representation for each patch. First, the sparse representation of each patch is independently computed over an overcomplete dictionary, and then a nonlocal weighted sparse coefficient is computed by averaging representations of similar patches. Since the sparsity can reveal relevant information from noisy patches, combining noisy and denoised patches' representations is beneficial to obtain a more robust estimate of the unknown sparse representation. The denoised patches are obtained by applying an off-the-shelf image denoising method and our method provides an efficient way to exploit information from noisy and denoised patches' representations. The experimental results on denoising and interpolation of spectral domain OCT images demonstrated the effectiveness of the proposed NWSR method over existing state-of the-art methods. PMID- 29575831 TI - In vivo high-resolution cortical imaging with extended-focus optical coherence microscopy in the visible-NIR wavelength range. AB - Visible light optical coherence tomography has shown great interest in recent years for spectroscopic and high-resolution retinal and cerebral imaging. Here, we present an extended-focus optical coherence microscopy system operating from the visible to the near-infrared wavelength range for high axial and lateral resolution imaging of cortical structures in vivo. The system exploits an ultrabroad illumination spectrum centered in the visible wavelength range (lambdac = 650 nm, Deltalambda ~ 250 nm) offering a submicron axial resolution (~0.85 MUm in water) and an extended-focus configuration providing a high lateral resolution of ~1.4 MUm maintained over ~150 MUm in depth in water. The system's axial and lateral resolution are first characterized using phantoms, and its imaging performance is then demonstrated by imaging the vasculature, myelinated axons, and neuronal cells in the first layers of the somatosensory cortex of mice in vivo. PMID- 29575830 TI - Quantitative real-time optical imaging of the tissue metabolic rate of oxygen consumption. AB - The tissue metabolic rate of oxygen consumption (tMRO2) is a clinically relevant marker for a number of pathologies including cancer and arterial occlusive disease. We present and validate a noncontact method for quantitatively mapping tMRO2 over a wide, scalable field of view at 16 frames / s. We achieve this by developing a dual-wavelength, near-infrared coherent spatial frequency-domain imaging (cSFDI) system to calculate tissue optical properties (i.e., absorption, MUa, and reduced scattering, MUs', parameters) as well as the speckle flow index (SFI) at every pixel. Images of tissue oxy- and deoxyhemoglobin concentration ( [ HbO2 ] and [HHb]) are calculated from optical properties and combined with SFI to calculate tMRO2. We validate the system using a series of yeast-hemoglobin tissue-simulating phantoms and conduct in vivo tests in humans using arterial occlusions that demonstrate sensitivity to tissue metabolic oxygen debt and its repayment. Finally, we image the impact of cyanide exposure and toxicity reversal in an in vivo rabbit model showing clear instances of mitochondrial uncoupling and significantly diminished tMRO2. We conclude that dual-wavelength cSFDI provides rapid, quantitative, wide-field mapping of tMRO2 that can reveal unique spatial and temporal dynamics relevant to tissue pathology and viability. PMID- 29575832 TI - [Circulating tumor DNA and targeted therapy in colorectal cancer]. AB - The detection of circulating tumor DNA is a quick, low cost and reliable approach of liquid biopsy of cancer. It has a wide range of applications for tumor screening because of its noninvasive, convenient and highly repeatable features. In terms of the targeted therapy in patients with colorectal cancer, serial monitoring of circulating tumor DNA, especially for the specific genetic alterations, can be used for prognosis, monitoring resistance, evaluation of therapeutic effects and screening combined targeted therapy. Therefore, it will guide more precise treatment of colorectal cancer. PMID- 29575833 TI - [Incidence and mortality of female breast cancer in China, 2014]. AB - Objective: To estimate the incidence and mortality of female breast cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for breast cancer prevention and control in China. Methods: There were 449 cancer registries submitting female breast cancer incidence and deaths data occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of female breast cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas) in 2014. The morphology verified cases (MV%) accounted for 87.42% and 0.59% of incident cases were identified through death certifications only (DCO%), with mortality to incidence ratio of 0.24. The estimates of new breast cancer cases were about 278 900 in China in 2014, accounting for 16.51% of all new cases in female. The crude incidence rate, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of breast cancer were 41.82/100 000, 30.69/100 000, and 28.77/100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 3.12%. The crude incidence rates and ASRIC in urban areas were 49.94 per 100 000 and 34.85 per 100 000, respectively, whereas those were 31.72 per 100 000 and 24.89 per 100 000 in rural areas. The estimates of breast cancer deaths were about 66 000 in China in 2014, accounting for 7.82% of all the cancer-related deaths in female. The crude mortality rate, age-standardized rate of mortality by Chinese standard population(ASRMC) and age-standardized rate of mortality by world standard population (ASRMW) of breast cancer were 9.90/100 000, 6.53/100 000, and 6.35/100 000, respectively, with a cumulative mortality rate of 0.69%. The crude mortality rates and ASRMC in urban areas were 11.48 per 100 000 and 7.04 per 100 000, respectively, whereas those were 7.93 per 100 000 and 5.79 per 100 000 in rural areas. The incidence and mortality rates of breast cancer were higher in areas than those in rural areas. The age-specific incidence rates of breast cancer increased greatly after 20 years old and peaked at the age group of 55-60. The age-specific mortality rates increased rapidly with age, particularly after 25 years old. They remained at a relative stable level from 55 to 65 years of age, and then increased dramatically and peaked in the age group of 85 and above. Conclusions: Breast cancer is still one of the most common malignant tumor threatening to famale health in China. The disease is more prevalent in urban areas at the age group of 55-60. Comprehensive prevention and control strategies referring to local status and age groups should be carried out to reduce the burden of breast cancer.

AB - Objective: To investigate the effect and mechanism of the antibacterial peptide cathelicidin secreted by tumor associated macrophages on the growth of colorectal cancer in mice. Methods: Azoxymethane (AOM)/ dextran sodium sulfate (DSS) method was used to establish a mouse model of colitis associated colon cancer. To induce tumor formation, cathelicidin antibody, IgG antibody (positive control) or PBS (negative control) was respectively injected into mice once every 3 days and lasted one month. Then the pictures of mice colon were taken, and the numbers of tumor were counted and evaluated. Expressions of cathelicidin in tumor associated macrophages isolated from tumor and adjacent normal tissues of mice were examined by quantitative RT-PCR (qRT-PCR) and Western blot. Expressions of the tumor proliferating antigen Ki-67, macrophage marker CD68 and cathelicidin in tumor and non-tumor tissues were determined by immunohistochemistry analysis. Apoptosis of cells from tumor tissues was analyzed by using TdT-mediated dUTP nick-end labeling (TUNEL). Results: In colon tumor tissues, cathlicidin strongly expressed in inflammatory cells (macrophages), but weakly expressed in tumor cells. The tumor number and size in mice injected with cathelicidin neutralizing antibody were 4.50+/-1.18 and (1.74+/-0.18) mm, respectively, significantly lower than 13.88+/-1.98 and (3.74+/-0.38) mm of mice injected with PBS (t=4.07, t=4.72; P< 0.01) and 15.25+/-1.82 and (3.40+/-0.36) mm of mice injected with IgG antibody (t=4.96, t=4.08; P<0.01). The Ki-67 positive rate of cells in tumor tissues of mice injected with cathelicidin neutralizing antibody was (28.20+/-3.44) %, significantly lower than (68.20+/-3.51) % of mice injected with PBS (t=8.135, P<0.01) and (69.20+/-3.41) % of mice injected with IgG antibody (t=8.461, P<0.01). Immunohistochemistry analyses showed that the expression of CD68 in tumor tissues of mice injected with cathelicidin antibody was significantly lower than that of mice injected with IgG antibody or PBS. TUNEL result showed that treatment with cathelicidin neutralizing antibody had negligible effect on the apoptosis of tumor cells. Conclusions: Cathelicidin secreted by tumor associated macrophages can promote the growth of colorectal cancer in mice, and neutralizing cathelicidin activity can inhibit the growth and proliferation of colorectal cancer. Cathelicidin mediated promotion of colon cancer proliferation may mainly be exerted by recruiting inflammatory cells such as macrophages into the tumor microenvironment.

AB - Objective: To evaluate the oncolytic effect of herpes simplex virus type 1 which carried recombined human granulocyte-macrophage colony-stimulating factor (HSV1 hGM-CSF) on the mouse breast cancer cell line 4T1 and compare the anticancer effects of HSV1-hGM-CSF, doxorubicin alone or combination on the breast cancer in mice. Methods: We investigated the cytotoxic effect on 4T1 cells in vitro, the cell growth, cell apoptosis and cell cycle of 4T1 cells treated with oncolytic HSV1-hGM-CSF at different MOIs (0, 0.5, 1 and 2) and doxorubicin at different concentrations (0, 2, 4 and 8 MUg/ml). The effects of oncolytic HSV1-hGM-CSF and doxorubicin on the tumor growth, survival time and their side effects on the mouse breast cancer model were observed. Results: Both oncolytic HSV1-hGM-CSF and doxorubicin significantly inhibited the proliferation of 4T1 cells in vitro. Doxorubicin induced the G(2)/M phase arrest of 4T1 cells, while the cytotoxicity of oncolytic HSV1-hGM-CSF was no cell cycle-dependent.At day 16 after treatment with doxorubicin and HSV1-hGM-CSF, the tumor volume of 4T1 tumor bearing mice were (144.40+/-27.68)mm(3,) (216.80+/-57.18)mm(3,) (246.10+/-21.90)mm(3,) (327.50+/-44.24)mm(3,) (213.30+/-32.31)mm(3) and (495.80+/-75.87)mm(3) in the groups of doxorubicin combined with high dose HSV1-hGM-CSF, doxorubicin combined with low dose HSV1-hGM-CSF, doxorubicin alone, high dose HSV1-hGM-CSF alone, low dose HSV1-hGM-CSF alone and control, respectively.Compared with the control group, both doxorubicin and HSV1-hGM-CSF treatment exhibited significant reduction of primary tumor volume in vivo (P<0.001). The median survival times were 48, 50, 40, 42, 43 and 37 days in the six groups mentioned above, respectively. The median survival period of doxorubicin alone, high dose HSV1-hGM CSF alone and low dose HSV1-hGM-CSF alone were significantly longer than that of control (P<0.05). Conclusion: Synergistic effect of sequential treatment with doxorubicin and oncolytic HSV1-hGM-CSF is observed in 4T1 mouse breast cancer. PMID- 29575836 TI - [Expression level and clinical significance of LncRNA HOXA11-AS in esophageal squamous cell carcinoma patients]. AB - Objective: To explore the expression of long noncoding RNA (lncRNA) HOXA11-AS in esophageal squamous cell carcinoma tissues and the relationship of HOXA11-AS level with clinical outcomes. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression level of HOXA11-AS in cell lines HET-1A, EC9706, EC109, and in tumor tissue and paired adjacent tissue samples from 73 ESCC patients who received surgical resection.The correlations of the expression level of HOXA11-AS with clinicopathological features and prognosis were also analyzed. Results: The relative expression levels of HOXA11-AS in tumor tissue and paired adjacent tissue were 0.832+/-0.387 and 2.486+/-1.087, respectively, with significant difference (P<0.001). The expression of HOXA11-AS was upregulated in 63.0%(46/73)ESCC tissues. The relative expression levels of HOXA11-AS in HET-1A, EC-9706 and EC-109 cells were 1.000, 23.553+/-3.221 and 17.217+/-1.968, respectively. The expression level of HOXA11-AS was upregulated in ESCC cell lines (P<0.001). High expression level of HOXA11-AS was correlated with histological grade and lymph node metastasis of ESCC patients (P<0.05). However, it was not associated with the age, gender, depth of infiltration and TNM staging (P>0.05). The median overall survival (OS) and median disease-free survival (DFS) of patients with low HOXA11-AS expression were 43 months and 42 months, respectively, significantly longer than 37 months and 28 months of patients with HOXA11-AS high expression (P<0.05). Cox model multivariate analysis showed that the expression of HOXA11-AS and lymph node metastasis were independent factors of poor prognosis of ESCC patients. Conclusions: The expression of HOXA11-AS is upregulated in esophageal cancer cell lines and tissues. High expression of HOXA11-AS is associated with poor prognosis of ESCC patients.Therefore, LncRNA HOXA11-AS may serve as a predictive marker of postoperative ESCC patients. PMID- 29575837 TI - [Clinical value of endoscopicultrsaonography and multi-slice spiral CT in Siewert IIand III type adenocarcinoma of esophagogastric junction]. AB - Objective: To investigate the clinical value of endoscopic ultrasonography (EUS) and Multi-slice Spiral CT (MSCT) in the preoperativestaging of tumor(T) and lymph node (N) metastasis in patients with SiewertIIand III typeadenocarcinoma of esophagogastric junction(AEG). Methods: Clinical data of 145 Siewert II and III type AEG patientswithout preoperative chemoradiotherapy were retrospectively reviewed. Theyall received preoperative EUS and MSCT examination and underwent surgical resection, and the results of EUS and MSCT were compared with their postoperative pathologic staging. Results: The sensitivity, specificity, and accuracy of EUS for T stage in Siewert II and III type AEG were higher than those of MSCT. The total accuracy of EUS and MSCT were 90.3% and 63.5%, respectively, and the difference was statistically significant (chi(2)=29.52, P<0.01). The sensitivity of EUS for T1, T2 and T3 were 89.5%, 91.1% and 85.2%, respectively, which were significantly higher than 42.1%, 66.7% and 29.6% of MSCT (chi(2)=9.47, P<0.01 for T1; chi(2)=8.07, P<0.01 for T2; chi(2)=17.40, P<0.01 for T3). In addition, the total accuracy of EUS and MSCT for lymph node metastasis status of Siewert II and III type AEG were 75.9% and 64.8%, respectively, showing a statistically significant difference(chi(2)=4.23, P=0.04). The sensitivity of EUS for N1 and N2 were 82.1% and 79.2%, respectively, which were significantly higher than 53.6% and 60.4% of MSCT (chi(2)=5.24, P=0.02; chi(2)=4.48, P=0.03). There was no statistical significance for sensitivity of EUS and MSCT in N0 and N3 (P>0.05). Conclusion: EUS diagnosis of T and N staging in Siewert II/III type AEG showed significantly greater performance than MSCT. PMID- 29575838 TI - [Study on the relationship between ultrasonographic features of papillary thyroid carcinoma and central cervical lymph node metastasis]. AB - Objective: To investigate the correlation between ultrasonographic features of papillary thyroid carcinoma and central cervical lymph node metastasis. Methods: We retrospectively analyzed 486 patients with papillary thyroid carcinoma(PTC), pathologically confirmed after surgery in Tianjin Medical University Cancer Institute & Hospital. All patients were divided into central cervical lymph node metastasis group and non-metastasis group. No lateral cervical lymph node metastasis was found in preoperative ultrasonography and postoperative pathology. The characteristics of the ultrasound was observed and analyzed. Results: 297 out of 486 patients with papillary thyroid carcinomahad central metastasis, and the other 189 cases did not. Take pathology results as a standard, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of preoperative ultrasound diagnosis in PTC patients with central cervical lymph node metastasis were 35.3%, 88.6%, 83.2%, 47.4%, 56.6%, respectively. Univariate analysis showed that multi-focus, taller-than-wide, diameter>1 cm, located in the lower pole, ill-defined margin, hypoechogenicity, micro calcification, capsule invasion more than 1/4 perimeter of papillary thyroid carcinoma were significantly associated with central cervical lymph node metastasis (all P<0.05). Multivariate analysis showed that diameter>1 cm, micro calcification, capsule invasion more than 1/4 perimeter of papillary thyroid carcinoma became independent risk factors of central cervical neck lymph node metastasis (all P<0.05). Conclusions: Preoperative description of ultrasonographical features has important value to assess central cervical lymph node metastasis in patients with papillary thyroid carcinoma. More information could be provided for clinical treatment. When the papillary thyroid carcinoma presented as diameter>1 cm, micro-calcification, and capsule invasion more than 1/4 perimeter of, there will be a greater risk of central cervical lymph node metastasis, and we shall suggest prophylactic central lymph cervical node dissection. PMID- 29575839 TI - [Clinicopathological features of second primary lung cancer and pulmonary metastasisin patients with breast cancer]. AB - Objective: To compare the clinicopathological characteristics of second primary lung cancer following breast cancer and lung metastases from breast cancer, and then to analyze the risk factors in breast cancer patients with second primary lung tumor. Methods: Clinical data of 55 breast cancer patients with second primary lung tumor and 205 breast cancer patients with solitary pulmonary metastasis in Shandong Cancer Hospital from January 2006 to January 2017 were retrospectively analyzed. The risk factors of primary lung cancer following breast cancer were analyzed using logistic regression model. Results: Second primary lung cancer in patients with first breast cancer accounted for approximately 21.2%(55/260) of pulmonary malignant solitary nodules, and 0.84%(55/6 580) of all breast cancer patients. The median intervals between the diagnosis of second primary lung cancer or lung metastasis and first breast cancer were 52 months and 42 months, respectively. These two groups showed significant difference between age, time interval between diagnoses, breast tumor size, axillary lymph node metastasis, estrogen receptor, molecular subtype (luminal B and triple-negative) and history of radiotherapy (P<0.05 for all). A multivariate logistic regression model confirmed that age (OR=1.088, P<0.001), breast tumor size(OR=0.480, P<0.001), and radiotherapy history (OR=3.460, P=0.004) were all independent factors for second primary lung cancer. Conclusions: For isolated pulmonary nodules in patients with breast cancer, especially for those with elder age, larger tumor size and radiotherapy history, we should distinguish the second primary lung cancer from pulmonary metastasis. The treatment regimen for lung metastasis and primary lung cancer in patients with breast cancer are entirely distinct. The timely histopathology examinations for pulmonary nodes in patients with breast cancer are recommended.

The hospitalization after operation is 8 days. No patient underwent abdomen hemorrhage or anastomotic leakage. Conclusion: Laparoscopic rectal cancer surgery with transanal natural orifice specimen extraction and resection appears to be feasible, safe and with promising efficacy for selected patients. PMID- 29575841 TI - [Clinical application of LDLT after reconstruction of IVC using artificial blood vessel in the treatment of HCC beyond Milan Criteria]. AB - Objective: To assess application of reconstruction of retrohepatic inferior vena cava using artificial blood vessel in right lobe living donor liver transplantation (LDLT) in the treatment of hepatocellular carcinoma (HCC) beyond Milan Criteria. Methods: The clinical data of 9 HCC patients who underwent right lobe liver transplantation after reconstruction of retrohepatic inferior vena cava using artificial blood vessel between June 2015 and Nov 2016 at Liver Transplantation Center of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. The liver of the patients was removed with retrohepatic inferior vena cava, and then the right donor graft was implanted by conventional orthotopic liver transplantation. Results: All 9 liver transplantations were performed successfully. The time of reconstruction of hepatic venous outflow of the donor graft was (22.6+/-3.0) min, anhepatic time was (45.0+/-7.1) min, and total operation time was (321.9+/-52.5) min. All patients recovered uneventfully, ICU and hospital stay day were (1.2+/-0.4) days and (18.4+/-3.0) days. 2 patients suffered from thrombosis of artificial blood vessel, one recovered after conservative treatment and another was treated by placement of vein stent. No abdominal/pulmonary infection and non-artificial blood vascular complications were found, and none died in perioperative period. Postoperative pathological results showed that all patients were hepatocellular carcinomas and vascular tumor thrombosis was found in 5 cases. All patients were follow up, 1 patient died of pulmonary and brain metastasis 10 months after operation. One patient survived with local recurrence of tumor in liver. The other patients had no tumor recurrence and metastasis. Conclusion: Replacement of retrohepatic inferior vena cava using artificial blood vessel in right lobe living donor liver transplantation is safe and feasible in the treatment of HCC beyond Milan Criteria, and might improve the resection rate of diseased liver and the prognosis of HCC patients after living donor liver transplantation.

PMID- 29575843 TI - [Application value of real-time three-dimensional contrast-enhanced ultrasound for morphological assessing of hepatocellular carcinoma before radiofrequency ablation treatment]. AB - Objective: To investigate the evaluating ability of real-time three-dimensional contrast-enhanced ultrasound (RT-3D-CEUS) for morphology of hepatocellular carcinoma (HCC) before radiofrequency ablation (RFA) treatment. Methods: Sixty patients with 88 targeted lesions were enroll in this study, who have received RFA in Hangzhou Xiasha Hospital. The pretreatment imaging data of CEUS and RT-3D CEUS were retrospective analysis. Morphological features were assessed according to the size and shape of the lesions, and were compared between two modalities with the post-treatment response as the reference standard. Results: The size of lesion measured by CEUS and RT-3D-CEUS was similar in 70 out of 88 lesions (group A). In the other 18 lesions, the size measured by RT-3D-CEUS was larger than that by CEUS (group B). For the shape analysis, 38 lesions were spheroid by CEUS and 34 lesions by RT-3D-CEUS; 47 lesions were oval by CEUS and 41 lesions by RT-3D CEUS; 3 lesions were irregular by CEUS and 13 lesions by RT-3D-CEUS. There were 78 lesions which shape assessed by two modalities consistently (group A'), and the other 10 lesions with inconsistent shape by two modalities (group B'). Three months follow-up results showed that 4 lesions appeared tumor residue (5.7%) in group A' and 6 lesions (33.3%) in group B'. There was significant difference between these two groups (P=0.004). In the group A', there were 6 lesions (7.7%) showed tumor residue, and 4 lesions (40.0%) in group B'. The difference between these two groups was also significant (P=0.012). Conclusion: RT-3D-CEUS could be used to assess the size and shape of HCC accurately which is associated with the response of RFA. PMID- 29575844 TI - [Multi-variated analysis of differential diagnosis in ultrasonography of idiopathic granulomatous mastitis and invasive ductal carcinoma]. AB - Objective: To evaluate the differential diagnosis of idiopathic granulomatous mastitis (IGM) and invasive ductal carcinoma. Methods: The ultrasonographic data of 37 IGM patients and 50 cases of IDC were analyzed retrospectively. The shape, growth direction, margin, internal echo, posterior echo, calcification, Adler blood flow classification, PSV(peak sestolic velocity), RI (resistance index)and elasticity scores were analyzed by chi(2) test and independent sample t test. The optimal cutoff values of age, PSV and RI were calculated by receiver operating characteristic (ROC) curve. Logistic regression analysis was used to calculate the odds ratio (OR) of ultrasonic variates in the diagnosis of both diseases. Results: There were no significant differences in the shape, margin, internal echo and blood flow grading between the two groups. The age, lesion growth direction, posterior echo, calcification, PSV, RI and elasticity were statistically different. The cut-of value of Age, PSV and RI were 38.5 years old, 13.20 cm/s, and 0.655. Logistic regression multi-variated analysis revealed that elastic score (OR=9.806) had the best value of the differential diagnosis, as well as calcification (OR=6.937), posterior echo decay (OR=4.613), RI (OR=3.257), lesion growth orientation (OR=3.198), and PSV (OR=1.202). Lesion shape, margin, internal echo, and Adler blood flow classification did not help in differential diagnosis. Conclusion: Ultrasound multi-parameter analysis has high value in IGM and IDC differential diagnosis.

AB - Objective: To investigate the clinical factors that affect the prognosis of patients with primary vaginal cancer. Methods: Clinical data of 118 primary vaginal cancer patients with pathological diagnosis and clinical follow-up data from the Department of Gynecology of Liaoning Cancer Hospital & Institute from 1999 to 2014 were collected and retrospectively analyzed. The relationship of prognosis and factors including age, history of hysterectomy, pathological types, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor size, tumor location and therapeutic methods were analyzed, respectively. Results: The median survival time of the 118 patients was 93 months. The survival rates of 1, 3, 5, 10 and 15-year were 89.7%, 68.1%, 60.4%, 37.3% and 19.0%, respectively.The results of univariate analysis showed that the FIGO stage, pathological types, tumor size, therapeutic methods and tumor location were related to the prognosis of patients with primary vaginal cancer (all P<0.05), while the patients' age, history of hysterectomy were not (all P>0.05). The results of Cox multivariate regression analysis indicated that FIGO stage (P=0.008), tumor location (P=0.001) and therapeutic methods (P=0.007) were independent prognostic factors of the patients with primary vaginal cancer. Conclusions: Prognostic factorsofpatients with primary vaginal cancer include FIGO stage, pathological types, tumor size, therapeutic methods and tumor location. Among them, therapeutic methods and tumor location are the independent prognostic factors.

PMID- 29575848 TI - Does learning style preferences influence academic performance among dental students in Isfahan, Iran? AB - PURPOSE: The present study aimed to identify the learning preferences of dental students and to characterize their relationship with academic performance at a dental school in Isfahan, Iran. METHODS: This cross-sectional descriptive study included 200 undergraduate dental students from October to November 2016. Data were collected using a 2-part questionnaire. The first part included demographic data, and the second part was a Persian-language version of the visual, aural, read/write, and kinesthetic questionnaire. Data analysis was conducted with the chi-square test, 1-way analysis of variance, and multiple linear regression. RESULTS: The response rate was 86.6%. Approximately half of the students (51.5%) had multimodal learning preferences. Among the unimodal group (48.5%), the most common mode was aural (24.0%), followed by kinesthetic (15.5%), reading-writing (8.0%), and visual (1.0%). There was a significant association between academic performance and the reading/writing learning style preference (P< 0.01). CONCLUSION: Multimodal learning styles were the most preferred. Among single-mode learning styles, the aural style was most common, followed by the kinesthetic style. Students with a reading/writing preference had better academic performance. The results of this study provide useful information for preparing a more problem-based curriculum with active learning strategies. PMID- 29575849 TI - Components of the item selection algorithm in computerized adaptive testing. AB - Computerized adaptive testing (CAT) greatly improves measurement efficiency in high-stakes testing operations through the selection and administration of test items with the difficulty level that is most relevant to each individual test taker. This paper explains the 3 components of a conventional CAT item selection algorithm: test content balancing, the item selection criterion, and item exposure control. Several noteworthy methodologies underlie each component. The test script method and constrained CAT method are used for test content balancing. Item selection criteria include the maximized Fisher information criterion, the b-matching method, the a-stratification method, the weighted likelihood information criterion, the efficiency balanced information criterion, and the Kullback-Leibler information criterion. The randomesque method, the Sympson-Hetter method, the unconditional and conditional multinomial methods, and the fade-away method are used for item exposure control. Several holistic approaches to CAT use automated test assembly methods, such as the shadow test approach and the weighted deviation model. Item usage and exposure count vary depending on the item selection criterion and exposure control method. Finally, other important factors to consider when determining an appropriate CAT design are the computer resources requirement, the size of item pools, and the test length. The logic of CAT is now being adopted in the field of adaptive learning, which integrates the learning aspect and the (formative) assessment aspect of education into a continuous, individualized learning experience. Therefore, the algorithms and technologies described in this review may be able to help medical health educators and high-stakes test developers to adopt CAT more actively and efficiently.

PMID- 29575851 TI - Molecular Screening of Small Biopsy Samples Using Next-Generation Sequencing in Korean Patients with Advanced Non-small Cell Lung Cancer: Korean Lung Cancer Consortium (KLCC-13-01). AB - BACKGROUND: Non-small cell lung cancer (NSCLC) is a common type of cancer with poor prognosis. As individual cancers exhibit unique mutation patterns, identifying and characterizing gene mutations in NSCLC might help predict patient outcomes and guide treatment. The aim of this study was to evaluate the clinical adequacy of molecular testing using next-generation sequencing (NGS) for small biopsy samples and characterize the mutational landscape of Korean patients with advanced NSCLC. METHODS: DNA was extracted from small biopsy samples of 162 patients with advanced NSCLC. Targeted NGS of genomic alterations was conducted using Ion AmpliSeq Cancer Hotspot Panel v2. RESULTS: The median age of patients was 64 years (range, 32 to 83 years) and the majority had stage IV NSCLC at the time of cancer diagnosis (90%). Among the 162 patients, 161 patients (99.4%) had novel or hotspot mutations (range, 1 to 21 mutated genes). Mutations were found in 41 genes. Three of the most frequently mutated genes were TP53 (151, 93.2%), KDR (104, 64.2%), and epidermal growth factor receptor (EGFR; 69, 42.6%). We also observed coexistence of EGFR and other oncogene (such as KRAS, PIC3CA, PTEN, and STK11) mutations. Given that 69.6% (48/69) of EGFR mutant patients were treated with EGFR tyrosine kinase inhibitors, EGFR mutant status had higher prognostic ability in this study. CONCLUSIONS: These results suggest that targeted NGS using small biopsy samples is feasible and allows for the detection of both common and rare mutations in NSCLC. PMID- 29575852 TI - Streptococcus suis: a re-emerging pathogen associated with occupational exposure to pigs or pork products. Part II - Pathogenesis. AB - Streptococcus suis is a re-emerging zoonotic pathogen that may cause severe disease, mostly meningitis, in pigs and in humans having occupational contact with pigs and pork, such as farmers, slaughterhose workers and butchers. The first stage of the pathogenic process, similar in pigs and humans, is adherence to and colonisation of mucosal and/or epithelial surface(s) of the host. The second stage is invasion into deeper tissue and extracellular translocation of bacterium in the bloodstream, either free in circulation or attached to the surface of monocytes. If S. suis present in blood fails to cause fatal septicaemia, it is able to progress into the third stage comprising penetration into host's organs, mostly by crossing the blood-brain barrier and/or blood-cerebrospinal fluid barrier to gain access to the central nervous system (CNS) and cause meningitis. The fourth stage is inflammation that plays a key role in the pathogen esis of both systemic and CNS infections caused by S. suis. The pathogen may induce the overproduction of pro-inflammatory cytokines that cause septic shock and/or the recruitment and activation of different leukocyte populations, causing acute inflammation of the CNS. Streptococcus suis can also evoke - through activation of microglial cells, astrocytes and possibly other cell types - a fulminant inflammatory reaction of the brain which leads to intracranial complications, including brain oedema, increased intracranial pressure, cerebrovascular insults, and deafness, as a result of cochlear sepsis. In all stages of the pathogenic process, S. suis interacts with many types of immunocompetent host's cells, such as polymorphonuclear leukocytes, mononuclear macrophages, lymphocytes, dendritic cells and microglia, using a range of versatile virulence factors for evasion of the innate and adaptive immune defence of the host, and for overcoming environmental stress. It is estimated that S. suis produces more than 100 different virulence factors that could be classified into 4 groups: surface components or secreted elements, enzymes, transcription factors or regulatory systems and transporter factors or secretion systems. A major virulence factor is capsular polysaccharide (CPS) that protects bacteria from phagocytosis. However, it hampers adhesion to and invasion of host's cells, release of inflammatory cytokines and formation of the resistant biofilm which, in many cases, is vital for the persistence of bacteria. It has been demonstrated that the arising by mutation unencapsulated S. suis clones, which are more successful in penetration to and propagation within the host's cells, may coexist in the organism of a single host together with those that are encapsulated. Both 'complementary' clones assist each other in the successful colonization of host's tissues and persistence therein. S. suis has an open pan-genome characterized by a frequent gene transfer and a large diversity. Of the genetic determinants of S. suis pathogenicity, the most important are pathogenicity islands (PAI), in particular, a novel DNA segment of 89 kb length with evident pathogenic traits that has been designated as 89K PAI. It has been estimated that more than one-third of the S. suis virulence factors is associated with this PAI. It has been proved that the virulent S. suis strains possess smaller genomes, compared to avirulent ones, but more genes associated with virulence. Overall, the evolution of the species most probably aims towards increased pathogenicity, and hence the most significant task of the current research is an elaboration of a vaccine, efficient both for humans and pigs. PMID- 29575853 TI - Paget disease of bone among hospitalized patients in Poland. AB - INTRODUCTION: Paget's disease (PDB) is a focal disorder of bone remodeling that occurs commonly in older people with decreasing prevalence reported in European countries. This disease is most often asymptomatic, but it can cause a variety of medical complications resulting in considerable morbidity and reduced quality of life. There is little information regarding the epidemiology of PDB in Poland. To the best of the authors' knowledge, this is the first large epidemiological analysis of this disease in Poland. OBJECTIVE: The aim of this study was to analyze factors that may be related to the PDB epidemiology among hospitalized patients in Poland. MATERIAL AND METHODS: The analysis was conducted on the basis of population-based administrative data, taken from a Polish hospital morbidity study carried out by the National Institute of Public Health between January 2008 - December 2014. RESULTS: Analyzed data covered 662 hospitalization records. The final study sample comprised 94 (41.8%) male and 131 (58.2%) female patients with first-time hospitalizations for PDB, with a significant predominance of females (P<0.02), and the predominance of patients living in urban (73%) than in rural areas (27%), P<0.001. The average age of the sample was 56.8 years (CI: 54.3 59.3; SD 18.8; range 1-93 years). The number of PDB cases hospitalized in Poland significantly decreased during the analyzed period of time. CONCLUSIONS: PDB is a rare disease with decreasing trends observed among hospitalized patients in Poland. The study results may suggest the existence of environmental risk factors for the development of PDB. PMID- 29575854 TI - Differences in physical activity and nutritionand silhouette-related behaviours in male and female students in selected European countries. AB - INTRODUCTION: As indicated by the WHO, lifestyle plays a unique role in human health, which in turn is determined to a great extent by physical activity and nutrition. It must be borne in mind that physical activity should be systematic and regulated by an age-appropriate exercise intensity. All this indicates that learning about students' lifestyle, with a particular focus on physical activity is vital as it these young people who aspire to the role of the future elites. OBJECTIVE: The aim of the study is to evaluate the level of physical activity, nutrition- and silhouette-related behaviours of male and female students to assess the relationships between these variables in students from the Visegrad Group countries. MATERIAL AND METHODS: The study was conducted in 2015 and involved 2,497 students attending three undergraduate levels aged - x - 21,76, (SD-1,80) - 1,211 males (48.5%) and 1,286 females (51.5%). The IPAQ long-form and a questionnaire by the Polish Chief Sanitary Inspector were used. RESULTS: Physical activity was significantly higher in male than female students. An important relationship was observed among the larger number of consumed meals, level of physical activity, and silhouette-related behaviours in male students, which was not the case with females. However, there was an important correlation between physical activity in males and females who exercised to increase or decrease body weight (musculature), and took medications to increase body weight (musculature). CONCLUSIONS: Both males and females showed pro-health attitudes related to the level of physical activity and nutrition- and silhouette-related behaviours. PMID- 29575855 TI - Forms of expressing anger in hospitalised Ukrainian post-deployedTM service members. AB - INTRODUCTION: Military actions and injuries sustained make returning to ordinary life and everyday routine a challenge which soldiers need to face. Research on this subject shows that the consequences of post-traumatic stress extends further, beyond the victim's everyday life, resulting in health problems and problems with social relationships. OBJECTIVE: The aim was to gather knowledge of the ways of expressing anger in a group of hospitalized Ukrainian post-deployed servicemen. A research study was conducted concentrating on the two forms of managing anger, i.e. releasing or suppressing anger, and posing the following question: 'How are they manifested in the hospitalized Ukrainian combat veterans? MATERIALS AND METHOD: The study included 35 hospitalized soldiers who had taken part in military operations in Ukraine (age: 34.61+/-9.23; age range: 21-56 years of age). The research was conducted in the hospitals in Lutsk. Measurements were conducted with the use of certified psychological tests, i.e. Anger Expression Scale (AES), medical documentation and oral reports given by the persons conducting the study. RESULTS: The average value of the suppressed anger indicator was 31.57+/-6.23 (p<0.05); respective value of the released anger 24.37 +/-6.34 (p<0.05). For released anger, results at the level of the upper quartile (Q3=28) and above were obtained by 28.57 % of the soldiers in the study, while in the case of repressed anger, the results obtained at the level of the upper quartile (Q3 = 36) and above that value were obtained by 34.27% of the soldiers/patients. CONCLUSIONS: The results obtained show that in the group of hospitalized patients/soldiers there is a higher level of repressed anger intensity than in the case of released anger. The study survey suggests that in their case expressing anger is usually a reaction to somebody's inappropriate-in their-eyes behaviour. Curbing anger takes on various forms, from trying not to express annoyance and/or rage, to trying to keep calm in spite of growing anger caused by other people's behaviours. PMID- 29575856 TI - Acceptance of illness by women with breast cancer. AB - INTRODUCTION: Despite great progress in the diagnostics and treatment, breast cancer still remains the most frequently diagnosed malignant cancer in women. The outcomes of cancer treatment depend, to a considerable extent, on the degree of acceptance of the illness. The objective of the study was determination of the level of acceptance of the disease among the examined women with breast cancer. MATERIAL AND METHODS: The study covered a group of 231 women who received treatment for breast cancer in the Rev. Bronislaw Markiewicz Subcarpathian Oncology Centre in Brzozow, south-eastern Poland, and conducted by the method of a diagnostic survey, using an author constructed questionnaire and the standard Acceptance of Illness Scale, adapted by Z. Juczynski. Statistical analyses were performed using the software IBM SPSS v. 21.0.0.1. The p values p<=0.05 were considered statistically significant. RESULTS: The mean level of acceptance of the illness in the examined group of women was 26.53 (SD = 7.71; Me = 26). The largest number of respondents (50.6%) obtained scores within the range of 20-29, according to the AIS Scale. From among the adopted variables, the level of acceptance of the illness significantly varied according to age and occupational activity. However, no such differences were confirmed according to the place of residence, marital status, education level, or the type of occupation performed. CONCLUSIONS: In the examined group of women, a mediocre level of acceptance of cancer was observed. The respondents' age and occupational situation exerted a significant effect on the level of acceptance of the illness. The results of the study should be considered as satisfactory because the number of women with a high level of acceptance of breast cancer was more than twice as high as those ones with a low acceptance of the disease. PMID- 29575857 TI - Ischemic cardiovascular disease in workers occupationally exposed to urban air pollution - A systematic review. AB - INTRODUCTION: Cardiovascular disease is the first cause of morbidity and mortality worldwide. Among several known risk factors, researchers also focus their attention on the chronic exposure to air pollution. There is much evidence that exposure to air pollution, especially to ultrafine particles, can damage the endothelium and can favour cardiovascular diseases in the general population. Occupational exposition could be an additive risk factor for the cardiovascular system. This article presents a scientific review of the linkage between occupational exposure to air pollution and ischemic heart disease. MATERIAL AND METHODS: A scientific review was undertaken, followed by PRISMA Statements. Observational studies were selected from several scientific databases, likesuch as Pubmed, Google Scholar, Nioshtic-2 and Reserchgate, searching for selected key words: police workers, professional drivers, mail carriers, filling station attendants, road cleaners, garage workers, motor vehicles and engine maintenance. All the key words were combined with "Boolean Operators" with the following words: cardiovascular (or cardiac) disease, cardiovascular function, cardiovascular system, ischemic heart disease, coronary disease, myocardial infarction. During the systematic research, the focus was on retrospective and prospective studies from January 1990 - December 2014. RESULTS: Both the retrospective and prospective studies showed an increased risk of ischemic heart disease in occupationally occupied people exposed to air pollution. Only one study presented a ly minor risk. CONCLUSIONS: The findings of this systematic review suggest a possible linkage between occupational exposure to urban air pollution, especially to motor exhaust and particulate, and ischemic heart disease. PMID- 29575858 TI - Effects of environmental pollution with aromatic hydrocarbons on endocrine and metabolic functions of the human placenta. AB - INTRODUCTION: Phenol and 1-hydroxypyrene are biological markers of exposure to polycyclic aromatic hydrocarbons (PAH) that have certain negative effects on parenchymal organs such as the human placenta. The literature presents only few reports regarding the effects of elevated PAH levels on the functions of the human placenta. OBJECTIVE: The aim of the work is to assess the effects of elevated PAH levels in excreted urine on the endocrine and metabolic functions of the human placenta obtained from a normal pregnancy. MATERIAL AND METHODS: Tissue material from 50 afterbirths from Plock constituted a study group, whereas 50 afterbirths from Kutno constituted a control group. Immunohistochemical reactions with the peroxidase method using LSAB kits (DAKO, Denmark) were performed. The extent and intensity of reactions were analysed. The levels of phenols and 1 hydroxypyrene in the excreted urine of pregnant women (undergoing delivery) were detected using gas chromatography and colorimetry. The statistical analysis used the PQStat v.1.6.2 software; moreover, t-student and chi-square tests were used. Differences were considered to be significant at the significance level of 95% (p<0.05). RESULTS: The levels of phenol and 1-hydroxypyrene in the excreted urine were demonstrated to be statistically significantly higher in patients living in the area of Plock. Statistically lower expression of placental glutathione transferase and lower immunohistochemical demonstration of the placental phosphatase activity were observed in placentas from Plock. It has been demonstrated that the expression of the oestrogen receptor activity and placental gonadotropin is significantly higher in placentas from areas not contaminated with aromatic hydrocarbons (Kutno). CONCLUSIONS: The course of pregnancy in the environment with elevated levels of aromatic hydrocarbons leads to impaired placental functioning and reduced endocrine and metabolic activity of the placenta. PMID- 29575859 TI - Prevalence and socioeconomic determinants of leisure time physical activity among Polish farmers. AB - INTRODUCTION AND OBJECTIVE: The aim of this study is to evaluate the leisure time physical activity of Polish farmers in the context of meeting health-related recommendations, and to diagnose the social and economic determinants. The analysis concerned leisure and transportation activities of various intensity and sedentary time. MATERIAL AND METHODS: Farmers (n=153) aged over 18 were selected from a representative sample of Polish society (n=2039). In order to evaluate LTPA, the long version of the IPAQ was used. Statistically significant differences between the variables were tested using non-parametric tests. The relationship between the amount of exercise recommended by the WHO and studied socio-demographic criteria was assessed using log-linear analysis. RESULTS: The WHO health recommendations were met by 33.3% of farmers. Shares in LTPA (19.1%) and transportation (19.2%) significantly increased the chance of achieving these norms (OR=12.54 and 0.07, respectively). Along with age (>=40 years) and income (>=3000 PLN/?750) of Polish farmers, the risk of insufficient physical activity increased. Average MET-min/week for LTPA was 299.8+/-583.4 and transportation - 521.2+/-1973.9. The average time of sitting during working days was 4.4+/-2.9, while it was 4.5+/-3.2 hrs/day during weekends. CONCLUSIONS: Health-promoting changes are necessary among Polish farmers, including an increase in the awareness of health benefits and the necessity of undertaking physically active ways of spending leisure time. It seems to be a legitimate action to develop a mini-tourist trail in the rural environment as a means of promoting physical activity also among women aged over 40, and from lower income groups, who are especially threatened by inactivity. PMID- 29575860 TI - Severity of work in opinions of rural women living in the Bieszczady region of south-eastern Poland. AB - OBJECTIVE: The objective of the study was recognition of the opinions of rural women living in the Bieszczady region of south-eastern Poland, concerning their perception of the degree of severity of work. The study was conducted among the inhabitants of the Cisna commune. MATERIAL AND METHODS: The basic research instrument was a questionnaire form containing 15 items. The study covered 101 women living in the Cisna commune in the Bieszczady. The self-reported degree of work load on a farm was analyzed among women who were occupationally active, and those who were not occupationally active. The effect of assistance from family members on the severity of work perceived by women was considered. RESULTS: The women in the study focused on agro-tourism, a few of them were engaged in agricultural work and the majority worked in household gardens. The study showed that occupationally active women work considerably longer, on average, and are the most loaded, compared to those not engaged in occupational activity. The mean daily time devoted to duties on a farm did not significantly differ between occupationally active and non-active women, and amounted to 380 and 320 minutes, respectively. The majority of women who were non-active occupationally evaluated their household chores as the highest work load. In turn, the women who undertook occupational activity assessed them as most burdensome, despite great help from their family. The body positions assumed while performing field work were: standing, standing-bent-over, and walking. The mean evaluations of work load while standing and standing-bent-over did not significantly differ, but affected the work load among women who, however, could not assess the severity of their work resulting from the body position assumed. PMID- 29575861 TI - Study on changing patterns of reproductive behaviours due to maternal features and place of residence in Poland during 1995-2014. AB - INTRODUCTION: The sharp decline in the total fertility rate in Poland coincided with broader socio-economic changes, which resulted in its reduction to the lowest level observed among the countries of Central and Eastern Europe. Objective. The aim of the study was to investigate and evaluate the changing patterns of reproductive behaviour in rural and urban areas, depending on the demographic and socio-economic features in Poland. MATERIAL AND METHODS: Information about live births in Poland in the years 1995-2014 were obtained from the Central Statistical Office. Registered cases of live births in rural and urban areas were analyzed considering the maternal features (age, marital status, main source of income). To evaluate the changes in fertility and comparisons between rural and urban areas, Joinpoint Regresssion was used. RESULTS: In 1995 2014, a shift in the age of highest fertility from 20-24 years to 25-29 years was observed. This occurred at the same time as a reduction in the fertility rate per 1,000 women aged 15-29 years, more pronounced in rural areas (95.8 to 60.0) than in urban areas (63.4 to 51.5), while in women aged 30-49 years, a faster increase in fertility was observed in urban areas (16.4 to 32.0) than in rural areas (27.5 29.2). Fertility trends between rural and urban areas differed significantly. A significant increase in live births for employed mothers was shown mainly in 2005 2009; later, the growth rate in rural areas was slower and in urban areas the growth trend stopped. CONCLUSIONS: The postponement of births and reduction of fertility in women aged 15-29 requires active measures aimed at creating favourable conditions for achieving economic independence for the younger generation, as well as combining work with raising children, especially in rural areas. ABBREVIATIONS: APC - annual percentage change; AAPC - average annual percentage change; CSO - Central Statistical Office; TFR - total fertility rate. PMID- 29575862 TI - Dietary intake of antioxidants and fats in the context of coronary heart disease prevention among elderly people. AB - INTRODUCTION: Some literature data indicate that the proper intake of exogenic antioxidants from food and the proper intake of fats can offer significant protection against coronary heart disease. OBJECTIVES: The estimation of total antioxidant capacity of food intake on the basis of Dietary Antioxidant Index (DAI), together with an assessment of the contribution of particular food products in DAI, and the evaluation of consumption of all dietary fats and frequency of consumption of products that are a source of fats among elderly people in Krakow, Poland. MATERIAL AND METHODS: 143 persons (73 women and 70 men) aged 65-80 were studied. None of them was under specialist medical control, including cardiological control. DAI was investigated on the basis of the Food Frequency Questionnaire (FFQ) which included 145 food items. DAI was measured using the method by Benzi and expressed as FRAP (the ability to reduce Fe3+ to Fe2+, measured in mMol/l). The daily intake of fats was estimated using the 24-h nutritional recall. The frequency of fats consumption was estimated with the usage of FFQ. For statistical analysis, chi2 test was used. RESULTS: The mean value of DAI of all studied persons was 34.27 + 11.72 mMol/l. The largest percentage of those studied had FRAP values in the range 25-35 mMol/l. The highest contribution in the total DAI value was found in fruit (36.2%), grains and cereal-based products (23.6%), and beverages (24.0%). The consumption of vegetables was on the fourth position (7.1%). The contribution of the remaining food products was low. The consumption of total fats (about 70g/24h) and saturated fatty acids (14% of energetic value) exceeded the recommendations. The participation of mono-and polyunsaturated fatty acids in the diets was not in accordance with recommendations. The most frequently consumed fats were animal fats (sausages, butter) and cakes, but the consumption of vegetable oils, fish, nuts and seeds of oil plants was too low. CONCLUSIONS: The majority of elderly people made mistakes in their nutrition. The enrichment in natural antioxidants of the diets of elderly people and the normalization of their fats consumption should become an important element of primary and secondary prophylaxis of cardiovascular diseases. PMID- 29575863 TI - Assessment of health, functioning and disability of a population aged 60-70 in south-eastern Poland using the WHO Disability Assessment Schedule (WHODAS 2.0). AB - INTRODUCTION: There is a growing number of older people in Poland. This phenomenon results in the need to assess their problems related with functioning in everyday life. This is the first study conducted in Polish society which evaluates the prevalence of disability and limitations in functioning by means of WHODAS 2.0 questionnaire. OBJECTIVE: Evaluation of the health, functioning and disability of people aged 60-70 years living in south-eastern Poland. MATERIAL AND METHODS: The researched material was a randomly- selected sample of 1,000 inhabitants of south-eastern Poland. The study was conducted by use of direct interviews applying the WHODAS 2.0. For the purpose of statistical analysis, measures of descriptive statistics and non-parametric tests of significance were used. RESULTS: Limitations in functioning were reported by 67.00% of participants aged 60-70 years, including 46.20% with a mild disability, 14.50% - moderate, 6.30% - significant and extremely large disability. The highest level of disability occurred in areas related to participation in social life (mean = 20.77), performing activities of daily living (mean = 17.42) and mobility (mean = 17.23). A significantly higher level of disability (p <0.0001)was observed among unmarried people, the elderly and those with a greater number of chronic diseases. Higher level of physical activity was associated with lower disability level in the studied population (p<0.009). CONCLUSIONS: Regarding the studied population, it was found that many health problems become worse over the years. The state of health that deteriorates with age causes limitations in daily functioning, which lead to disability, activity limitations and participation in everyday life. The progressive ageing of the Polish population will cause an increasing demand for medical care and on the social services. PMID- 29575864 TI - Demographic characteristics and AMH levels in rural and urban women participating in an IVF programme. AB - OBJECTIVE: The primary aim of this preliminary study was to compare the IVF results of couples living in rural and urban areas. Additionally, the ovarian reserve parameters, such as AMH concentrations, were compared for the same groups. MATERIAL AND METHODS: The database of 1,265 women undergoing in vitro fertilization at the Invicta Fertility Center between May 2011-July 2012 were retrospectively analyzed. Women undergoing their first assisted reproductive technology cycle with ICSI, stimulated according to the long protocol, and whose AMH levels were measured using the same DSL kit, were selected. Ultimately, 651 women were included in the study. All participants were categorized based on the area where they live: rural areas, small towns (<100,000 inhabitants) and large cities (>100,000). RESULTS: The mean age of the patients living in large cities was significantly higher in comparison to those from rural areas and small towns. A significantly higher pregnancy body mass index (BMI) was found in women from rural areas in comparison to the women living in small and large towns. Serum AMH and inhibin B concentrations, number of ampules of gonadotropins, and antral follicle count (AFC), did not differ significantly among the groups. The study showed no significant differences among the groups in terms of clinical pregnancy rate, both per started cycle and per embryo transfer. CONCLUSIONS: No significant differences were found in IVF outcomes among the groups inhabiting rural areas, small and large cities. PMID- 29575865 TI - Parity does not affect diabetes complications in women with type 1 diabetes. AB - INTRODUCTION: The problem concerning the impact of pregnancy on diabetic complications is a matter for discussion as there is some evidence suggesting that pregnancy may trigger development or progression of diabetic chronic complications. However, currently available data concerning this issue is still controversial. OBJECTIVE: The aim of the study was to evaluate the impact of obstetric history on the development of chronic microangiopatic and macroangiopatic complications in type 1 diabetic women. MATERIAL AND METHODS: The retrospective study comprised 226 white Caucasian type 1 diabetic women, including 190 parous and 36 nulliparous women. Anthropometric data, information concerning the course of the disease, including metabolic control and chronic complications, together with obstetric history, were registered. RESULTS: Parous women were older (p<0.001), but did not differ significantly regarding metabolic control in the course of the disease (p>0.05) and diabetes duration (p>0.05) from nulliparous subjects. There were no significant differences in the incidence (p>0.05) nor onset (p>0.05) of chronic diabetes complications between the groups. The number of deliveries did not correlate with either the incidence nor the onset of chronic complications. Longer DM duration at the moment of first delivery was related to the higher incidence of retinopathy (p<0.01), nephropathy (p<0.05) and neuropathy (p<0.001). CONCLUSIONS: The incidence of chronic diabetic complications does not differ between parous women and the subjects that were never pregnant, and is not related to the number of pregnancies. PMID- 29575866 TI - Gender, age, social disadvantage and quitting smoking in Argentina and Uruguay. AB - INTRODUCTION: Cessation of tobacco use has the potential to provide the greatest immediate benefits for tobacco control. Understanding the social determinants of smoking cessation is an essential requirement for increasing smoking cessation at the population level. The purpose of this study was to analyze the socio-economic dimensions associated with cessation success among adults in Argentina and Uruguay. MATERIAL AND METHODS: Data from the Global Adult Tobacco Survey (GATS), a cross-sectional, population-based, nationally representative survey conducted in Argentina (n=5,383) and Uruguay (n=4,833) was utilized. Univariable and multivariable logistic regression analyses with results being presented as odds ratios (OR) with 95% confidence intervals were applied to study differences among those respondents who sustained smoking abstinence (>=1 year) and those who continued smoking. RESULTS: The GATS study revealed that social gradients in tobacco quitting exist in Argentina and Uruguay. Being aged 25-34, particularly men in Uruguay, women in Argentina, low educated men in Argentina and having a lower asset index were associated with reduced odds for quitting. CONCLUSIONS: Factors that are driving differences in smoking cessation between diverse social groups in Latin America countries need to be considered when implementing relevant interventions to ensure tobacco control strategies work effectively for all population segments. PMID- 29575867 TI - Pregnancy planning and risk behaviours - a survey of women's experiences in selected European countries. AB - Pregnancy, a special period in a woman's life, should be preceded by proper preparation: a positive attitude to procreation, selection of optimum time for becoming pregnant, starting prevention of neural tube defects, restriction of the use of drugs, smoking, etc. The aim of this study was to determine the effect of pregnancy planning and antenatal classes on the use of stimulants during pregnancy. The study group included 877 women living in 7 European countries, and their experiences of planning pregnancy and substance abuse during pregnancy were investigated. In about a half (50.3%) of respondents the pregnancy was planned. The highest percentage of mothers who planned pregnancy was recorded in Poland and Bulgaria (about 76%). By contrast, in Germany the proportion of mothers who planned pregnancy was the lowest (46.2%). Surprisingly, they became pregnant despite very frequent use of birth control (96.7%). On average, 17.3% of respondents disclosed that they drank alcohol or coffee, smoked cigarettes or used psychoactive drugs during pregnancy. Among women who did not plan to be pregnant, the use of stimulants was recorded more often. However, pregnancy planning only slightly inclined women to stop the consumption of stimulants. Attendance at antenatal classes did not have any significant effect on the use of stimulants. PMID- 29575868 TI - How do patients perceive ambulatory psychiatric care and what are their needs? AB - INTRODUCTION AND OBJECTIVE: The quality of a doctor-patient relationship plays a vital role in all fields of medicine. In the case of psychiatry, this role is special as it provides the foundation for the whole therapeutic process. The aim of this study was to investigate the patient's perspective on psychiatric visits: patient's attitudes towards the psychiatrist, patient's view of the patient psychiatrist relationship, and the patient's needs and expectations from this relationship. MATERIAL AND METHODS: 615 psychiatric outpatients responded to the anonymous questionnaires connected with their attitudes towards the psychiatrist, evaluation of the doctor, and expectations from psychiatric care. The study was conducted in 10 out of 30 public centres for psychiatric care in north-eastern Poland. RESULTS: Generally, the patients liked and positively evaluated their psychiatrists. Patient's liking for the doctor was connected with the feeling that the doctor also liked the patient, as well as with perceiving the doctor as competent and willing to meet the patient. The longer the treatment with a particular psychiatrist and the rarer need to consult the doctor, the more positive attitude and evaluation of the doctor patients had. According to the patients, the most significant expectations were associated with both conversation with the doctor and receiving emotional support. CONCLUSIONS: The key phase for forming the patient-psychiatrist relationship was the first stage of cooperation in which patients created their attitudes towards the doctor without modifying them at further stages. Thus, further studies on learning and developing the ability to establish the relationship with the patient, inspiring the patient's trust and making psychiatric appointments comfortable from the first meeting, will be highly valuable. PMID- 29575869 TI - Volatile oil composition of Carthamus Tinctorius L. flowers grown in Kazakhstan. AB - INTRODUCTION: Carthamus tinctorius L. is commonly known as Safflower. C. tinctorius extracts and oil are important in drug development with numerous pharmacological activities in the world. This plant is cultivated mainly for its seed which is used as edible oil. For a long time, C. tinctorius has been used in traditional medicines as a purgative, analgesic, antipyretic and an antidote to poisoning. It is a useful plant in painful menstrual problems, post-partum haemorrhage and osteoporosis. OBJECTIVE: The subject of this study is the seeds of Kazakhstan species of 'Akmai' safflower, collected in the flowering stage in Southern Kazakhstan. Volatile oil was carry out to study the component composition of Kazakhstan 'AkMai' safflower flowers. MATERIALS AND METHOD: Pale yellow oily extracts were obtain by varying the process parameters. The volatile oil obtained by hydrodistillation of the petals Carthamus tinctorius L. was analyzed by gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.175 % (v/w). 20 compounds representing 99.81% of the oil were characterized. The volatile oil was found to be rich in undecanoic acid, octane, 2-nonen -1-ol, hexadecanal, dodecanal, dec-2-en-1-ol, nonanoic acid, tetradecanoic acid, 2 pentadecanone, 6,10,14-trimethyl, 1,2-benzenedicarboxylic acid, isobutyl-beta-phenylpropionate, 1.3-cyclohexadiene, myrtenoic acid, octadecanoic acid, heneicosanoic acid, 2(3H)-furanone, 4,4-dipropylheptane, hexcosane,1-eicosanol, as well as heptocosane. RESULTS: Volatile oil from the flowers of the Kazakhstan safflower species 'Ak-Mai' were investigated by GC/MS which allowed the detection of 20 compounds. Biologically active complex of the flower of the Kazakhstan safflower species 'Ak-Mai' was released for the first time by using this oil. PMID- 29575870 TI - How is the process of setting micronutrients recommendations reflected in nutrition policies in Poland? The case study of folate. AB - INTRODUCTION AND OBJECTIVE: Ensuring the adequate intake of micronutrients by populations is an important aspect of public health. This study aims to elucidate the process of setting nutrition recommendations and the development of subsequent policies associated with micronutrients in Poland by using the case study of folate. MATERIAL AND METHODS: The study was based on 13 interviews conducted between October 2010 - February 2011, and desk research comprising a review of the associated scientific literature and relevant documents, such as scientific opinions and reports of the meetings of scientific committees. The interviews were conducted within the EURRECA (EURopean micronutrient RECommendations Aligned) Network of Excellence in the frame of the European Union's 6th Framework Programme. RESULTS: Since 1997, the Experts Group of the Ministry of Health recommended that all women of childbearing age should consume folic acid as a supplement to prevent neural tube defects in their offspring. The fortification of foodstuffs with folic acid is not obligatory. This study describes the revision of the folate nutrient recommendation and the process by which strategies to increase the intake of this vitamin by the Polish population were identified. The institution responsible for the choice and implementation of folate policy is the Ministry of Health and the National Food and Nutrition Institute is responsible for setting/updating the nutrient recommendations. CONCLUSIONS: The current Polish nutrition recommendations for folate are consistent with the levels set by most other countries. The constant improvement of nutritional knowledge on folate among consumers, especially young women, is necessary. PMID- 29575871 TI - Regional differences in access to health care in Poland from the perspective of health care resources. AB - OBJECTIVE: To examine disparities in access to the public in Poland, in association of the resources of health care, socio-economic development of Provinces and their level of urbanization. MATERIAL AND METHODS: The Provinces were divided into four groups, using the quartile method, according to the urbanization and level of socio-economic development. The socio-economic development level was identified by the Human Development Index (HDI) for each Province. The urbanization level of each Province was determined by the Index of Urbanization (URBI). Disparities level to access to public health care was identified by taxonomic measure of accessibility (TMA), calculated using resources of health care data. TMA index was compared in the different regions, depending on the level of HDI and URBI. RESULTS: There was no linear relationship between accessibility to public healthcare and socio-economic development of each tested region, nor between accessibility to public health care in the Provinces and their urbanization level. During the study, the correlation between the TMA and HDI and URBI alsdo produced a negative result. CONCLUSIONS: An insufficient number of physicians and the limited value of contracts within the public health service may cause a drop in the availability of the public medical service sector, regardless of regional level of urbanization and socio-economic development. PMID- 29575872 TI - Premature atherosclerosis after treatment for acute lymphoblastic leukemia in childhood. AB - INTRODUCTION: Late cardiovascular complications are the leading causes of morbidity and mortality in patients treated for common malignancies of childhood. Late cardiotoxicity include increased development of atherosclerosis and atherosclerosis - related diseases. An evaluation of the endothelium can be made based on the measurement of endothelium-derived blood vasoactive factors, such as cytokines and adhesion molecules. Their elevated serum levels may serve as sensitive indicators of early atherosclerotic lesions in high risk patients. Currently, assessment of common carotid intima-media thickness has emerged as one of the more powerful tools for evaluation of subclinical atherosclerosis. The purpose of this study was to compare these parameters between patients after antineoplatic treatment compared to persons not exposed to such factors. MATERIAL AND METHODS: Early progression of atherosclerotic disease was evaluated in 64 survivors treated for Acute Lymphoblastic Leukaemia (ALL) in childhood, and in a control group of 36 healthy volunteers. Blood serum concentrations of selected new biomarkers, indicative of endothelial damage and inflammatory activity, were measured, including intercellular adhesion molecule-1 (sICAM-1), endothelial leukocyte adhesion molecule-1 (E-selectin), thrombomodulin (TM), interleukin 6 (IL-6), and high-sensitivity C-reactive protein (hs-CRP). The common carotid intima-media thickness (IMT) was also assessed via ultrasound examination. RESULTS: Significantly higher blood concentrations of sICAM-1 adhesive molecule (229.3+/-62.2 ng/mL vs. 199.9 +/- 63.3 ng/ mL, p=0.0072) and IL-6 (2.1 +/- 2.7 pg/mL vs. 1.9 +/- 3.6 pg/mL, p=0.0414) were found in ALL survivors compared with control subjects. Concentration of hs-CRP was also higher in the ALL group: 1.3 +/- 2.2 ug/mL vs. 0.6 +/- 0.9 ug/mL. This difference was close to statistical significance (p=0.0599). The mean IMT values for right and left carotid arteries were higher in ALL patients after antineoplastic therapy, compared with healthy subjects (IMT-R 0.056+/-0.008 mm vs. 0.052+/-0.003 mm; p=0.0021; IMT-L 0.057+/ 0.009 mm vs. 0.052+/-0.003 mm; p=0.0051). CONCLUSIONS: Survivors of childhood ALL in the examined group demonstrated elevated concentrations of selected new biomarkers and increased IMT values, compared to controls, which may confirm the occurrence of endothelial injuries in blood vessels. This study indicates that subjects treated for childhood malignancy are at a higher risk of prematurely developing atherosclerosis. PMID- 29575873 TI - Prevalence of dental erosion among 18-year-old adolescents in the borderland districts of Lviv (Ukraine) and Lublin (Poland). AB - INTRODUCTION AND OBJECTIVE: Recent epidemiological studies have shown an association between dental erosion occurrence and changes in lifestyle and dietary habits in both developed and developing countries, and now affects different regions of the world. Furthermore, in current literature, studies have shown that the prevalence of erosive tooth wear has increased particularly among the younger population. The aim of the study was to assess the prevalence and severity of erosive tooth wear among 18-year-old adolescents in the districts of Lviv (Ukraine) and Lublin (Poland). MATERIAL AND METHODS: College students (254 subjects) aged 18, living in the Lviv and Lublin districts were examined. Erosive lesions presented in the teeth were assessed on the basis of the BEWE (Basic Erosive Wear Examination) index. RESULTS: Among the 137 patients living in the Lublin district, 70 were females and 67 were males, while in the Lviv district, 60 women and 57 men were examined. In both districts, the following numbers of rural patients were examined: 66 in Lublin district and 56 in Lviv district; for urban inhabitants, the numbers were 71 in Lublin and 61 in Lviv. Analysing the BEWE values, it was noted that higher BEWE values, and resulting from them significant differences were observed in both male and female groups living in Lublin, compared with Lviv inhabitants. Based on clinical examination and statistical analysis, the occurrence of lesions of an erosive character in at least one sextant were observed in 59.85% of patients from Lublin district, and in 42.74% of patients from Lviv district. CONCLUSIONS: On the basis of the conducted study in the Polish and Ukrainian groups of 18-year-old adolescents living on the borderland, it can be stated that dental erosion is a problem noticeable in both groups of cohorts, but with higher prevalence in the Lublin district. PMID- 29575874 TI - Influence of growth hormone therapy on selected dental and skeletal system parameters. AB - INTRODUCTION: Growth hormone deficiency (GHD) is one of the main indications for growth hormone therapy. One characteristic of this disease is bone age delay in relation to the chronological age. Pituitary dysfunction negatively affects the growth and development of the jaws and teeth of the child. The secretion of endocrine glands regulates growth, development, and gender differentiation. It also controls the growth of bones and teeth, regulates metabolism of calcium and phosphate, proteins, lipids and carbohydrates. The primary role in the endocrine system is played by the pituitary gland which is responsible for the production of somatotropin [1]. Dysfunction of the pituitary gland has a negative effect on the growth and development of long bones in the body, and may have an adverse effect on the development of maxilla, mandible and dentition of a child. There is some information in the literature that dental age is delayed in short stature children; the replacement of deciduous teeth by permanent teeth is also delayed, and newly erupted permanent teeth often require orthodontic treatment. Applying hormonal therapy positively affects the process of replacement of dentition [2, 3, 4, 5, 6]. OBJECTIVES: The aim of the study was to assess bone and dental age, as well as analyze the state of dentition in children diagnosed with GH deficiency treated with growth hormone, depending on the duration of treatment. MATERIAL AND METHODS: The study material consisted of 110 children (27 males, 83 females), hospitalized for somatotropin hypopituitarism in the Department of Paediatric Endocrinology and Diabetology at the Medical University of Lublin, Poland. The mean birth age was 13 years (156 months) with a standard deviation of 2 years and 6 months (30 months). 47 children (43%) started treatment with the growth hormone (group starting treatment) and 63 children (57%) whose treatment was started 2-3 years previously (group in the course of treatment). The control group consisted of 41 generally healthy children (15males, 25 females) with ENT problems, such as hypoacusis and a condition after nasal injury, hospitalized in the Department of Paediatric Otolaryngology at the Medical University of Lublin, Poland. The mean age was 11 years and 5 months (137 months) with standard deviation of 2 years and 5 months (29 months). Informed consent was obtained from the parents. The study was approved by the Bioethical Committee at the Medical University of Lublin (Resolution No. KE-0254 /216 /2012). PMID- 29575875 TI - Assessment of the efficacy of ofatumumab in patients with chronic lymphocytic leukaemia treated in the Department of Haematooncology and Bone Marrow Transplantation of the Medical University in Lublin - Prelimary results. AB - INTRODUCTION: Despite significant recent advances in the treatment of chronic lymphocytic leukaemia (CLL), most cases of the disease are still incurable. Treatment with monoclonal antibodies, such as ofatumumab, is one of the new therapeutic options. OBJECTIVE: Retrospective analysis of the efficacy of ofatumumab in patients with chronic lymphocytic leukaemia (CLL) treated in the Haematooncology and Bone Marrow Transplantation Department of the Medical University of Lublin, Poland, during 2011-2013. MATERIAL AND METHODS: The analysis included 5 patients (3 women and 2 men), aged 47-65, with Rai stage II IV CLL, after a few lines of treatment. Three patients received ofatumumab in monotherapy and 2 patients received ofatumumab in combination with cyclophosphamide (50 mg/day) and dexamethasone (40 mg/day). All patients included in the study were diagnosed with an active form of leukaemia with symptoms such as lymphocytosis or massive lymphadenopathy. RESULTS: All patients responded to the treatment. Within the first 8 weeks of the treatment, levels of white blood cells returned to normal in patients with baseline lymphocytosis (3 patients). An increase in platelet levels was reported in 3 patients. Haemoglobin levels were higher or comparable to the baseline values in all studied patients after the completion of immunotherapy. In the patient with massive lymphadenopathy and hepato- and splenomegaly, the size of the lymph nodes, spleen and liver decreased and neutrophil levels increased. Time of progression was 5-12 months, and in one patient partial remission has been maintained. The treatment was well-tolerated in most cases. Asymptomatic neutropenia and an infection with Candida glabrata were observed. CONCLUSIONS: Ofatumumab may be a new and safe therapeutic option for patients with CLL after a few lines of treatment. PMID- 29575876 TI - The effect of MLS laser radiation on cell lipid membrane. AB - INTRODUCTION: Authors of numerous publications have proved the therapeutic effect of laser irradiation on biological material, but the mechanisms at cellular and subcellular level are not yet well understood. OBJECTIVE: The aim of this study was to assess the effect of laser radiation emitted by the MLS M1 system (Multiwave Locked System) at two wavelengths (808 nm continuous and 905 nm pulsed) on the stability and fluidity of liposomes with a lipid composition similar to that of human erythrocyte membrane or made of phosphatidylocholine. MATERIAL AND METHODS: Liposomes were exposed to low-energy laser radiation at surface densities 195 mW/cm2 (frequency 1,000 Hz) and 230 mW/cm2 (frequency 2,000 Hz). Different doses of radiation energy in the range 0-15 J were applied. The surface energy density was within the range 0.46 - 4.9 J/cm 2. RESULTS: The fluidity and stability of liposomes subjected to such irradiation changed depending on the parameters of radiation used. CONCLUSIONS: Since MLS M1 laser radiation, depending on the parameters used, affects fluidity and stability of liposomes with the lipid content similar to erythrocyte membrane, it may also cause structural and functional changes in cell membranes. PMID- 29575877 TI - Social functioning and the quality of life of patients diagnosed with schizophrenia. AB - INTRODUCTION: Schizophrenia to a considerably great degree impairs the social functioning of the persons affected in the spheres of interpersonal and occupational contacts, as well as self-care. It brings about serious cognitive, perceptual, motor and emotional deficits, inevitably leading to the social withdrawal of patients. This phenomenon may assume various forms, from the limitations in interpersonal relations, through narrowing these relations to only some circumstances, to the total cessation of social contacts. OBJECTIVE: The objective of the study is presentation of the most important problems related with social functioning and quality of life of patients diagnosed with schizophrenia, based on scientific studies conducted in Poland and worldwide. STATE OF KNOWLEDGE: The family of a schizophrenia patient exerts a great effect on the social functioning. While undertaking proper actions the family may become a co-therapist and significantly facilitate the patient's adjustment to life in society and his/her playing a specified role. Analysis of disorders in social functioning of patients with schizophrenia, in the context of social cognition, indicates the fact that these disorders have their source in the lack of capabilities for identification of own and other people's internal states, whereas mentalization is the essence of social cognition. CONCLUSIONS: Therapy, any psychosocial impact as well as rehabilitation, neutralizes the causes for patients' withdrawal from social life. Training of social skills is necessary which teaches patients to return to the situation when they would be able to function properly in their environment. PMID- 29575878 TI - Solec Spa - worldwide unique properties of Polish health resort in the service of rural medicine. AB - Solec Spa is health resort in south-eastern Poland.

The effectiveness of the Solec waters is proven in: inflammatory and autoimmunological locomotor system diseases, degenerative joint disorders (osteoarthritis), post-traumatic and post-operative orthopedic diseases, skin diseases and allergic disorders. One of the main indications for balneotherapy in Solec Spa and Busko Spa is chronic brucellosis. PMID- 29575879 TI - Influence of socio-economic factors on emotional changes during the postnatal period. AB - OBJECTIVES: The aim of the study was to identify socio-economic factors that may influence the emotional changes which occur among new mothers in the first days postpartum. MATERIAL AND METHODS: A group of 541 women completed a questionnaire consisting of 30 multiple-choice questions, Edinburgh Postnatal Depression Scale (EPDS), and Hospital Anxiety and Depression Scale (HADS). Statistical calculations were performed with the use of Statistica v.10 and Cytel Studio v. 9.0.0. RESULTS: The findings revealed the presence of factors which might increase the risk of mood disorders during the postpartum period. CONCLUSIONS: Women who demonstrate warning symptoms should be screened for postnatal emotional changes and mood swings during their hospitalization after delivery. EPDS seems to be a suitable tool for early detection of emotional disturbances. PMID- 29575880 TI - Modifiable lifestyle factors and ovarian cancer incidence in women. AB - INTRODUCTION: A correct diet plays an important role in the prevention of malignant tumours. The risk of the disease may be reduced by introducing a number of changes to the daily diet. The most important changes concern the amount of fat in the diet, dietary fibre, antioxidants in the food and the reduction of substances having a significant impact on the development of malignant tumours. OBJECTIVE: The aim of the study is to analyse the role of selected modifiable lifestyle factors affecting the development of ovarian cancer. MATERIAL AND METHODS: The study covered healthy women and women with diagnosed ovarian cancer. A total of 850 women aged between 21-84 were studied. The study included women visiting the Gynaecology and Obstetrics Hospital of the University of Medical Sciences in Poznan, Poland, between 2011-2013. Patients recognized with malignant ovarian cancer were qualified into the study based on the histopathological examination of the material obtained during surgery. RESULTS: Respondents who consumed fruit and vegetables several times a week have the odds ratio OR = 0.29 level; 95% CI 0.04-2.01 (p =.2085), compared to women not consuming fruit and vegetables at all. Consumption of 100 g of French fries and potato chips several times a week, results in a 2-fold increase in ovarian cancer. The OR for this group of women amounts to 2.06; 95% CI 0.53-7.99 (p=.2966). CONCLUSIONS: A diet rich in fruit and vegetables, including bulb vegetables, and grain products containing whole grains, should be introduced. It is recommended that the consumption of popular fast foods be eliminated. PMID- 29575881 TI - Prevalence of Borrelia burgdorferi in ticks removed from skin of people and circumstances of being bitten - research from the area of Poland, 2012-2014. AB - INTRODUCTION: During feeding, the tick sucks blood from the host along with the pathogens that are in the blood, simultaneously exchanging its own pathogens with the host. Humans can also be a host. It is important to understand the most typical circumstances in which people might become infected with Borrelia burgdorferi. This knowledge will help to prepare health education programmes aimed at the prevention of Lyme disease and other tick-borne diseases. OBJECTIVE: The aim of the study was to determine the percentage of ticks infected with Borrelia burgdorferi sensu lato, depending on the circumstances of getting bitten. MATERIAL AND METHODS: The research material consisted of ticks acquired from people who had been bitten, and questionnaires completed by these people. 510 ticks were acquired from 257 females and 253 males. Following delivery of a tick for testing, the stage of its development was determined and a molecular assay of Borrelia burgdorferi DNA performed. RESULTS: A positive result of the nested-PCR test was obtained in 78 ticks, which represents 15.30% of all ticks. The infected ticks were collected from male (41 ticks - 52.56%) and female subjects (37 ticks - 47.44%). The biggest number of infected ticks were collected in autumn (54 ticks - 69.23%) and from people who had been into forests (44 ticks - 56.41%). Among the people from whom the infected ticks were acquired, the dominating group included persons over 16 years of age (53 persons - 67.95%) and children aged 0-5 years (16 persons - 20.51%). One in four infected ticks were acquired from the southwestern (20 ticks - 25.64%) and eastern regions of Poland (21 ticks - 26.92%). CONCLUSIONS: Infestation of ticks infected with Lyme disease spirochete in this study proved to be variable and depend on the season, the area of tick attack and the region in Poland. The results of the study clearly show that ticks infected with Borrelia burgdorferi inhabit all regions of Poland. The results are consistent with National Institute of Hygiene data which indicates that Lyme disease cases are recorded in all regions of Poland. PMID- 29575882 TI - Evaluation of the frequency of childhood hospitalization due to thermal injuries in the Provincial Polyclinical Hospital in Torun, Poland, 2007-2011. AB - INTRODUCTION: Burns constitute the most common and severe injuries suffered in childhood. OBJECTIVE: The study was aimed at providing a retrospective analysis of the etiology, location, extent and depth of burns, as well as treatment methods and length of hospital stay. MATERIAL AND METHODS: A retrospective analysis of 508 cases of children treated due to a thermal injury between 1 January 2007 31 December 2011 was conducted at the Department of Paediatrics, Urology and Paediatric Surgery, Children's Hospital, L. Rydygier Provincial Hospital in Torun, Poland. RESULTS: The sample group included more boys (58.9%) than girls (41.1%). The most numerous group comprised children aged 1-2 years (44.5%). Burns were largely suffered at home (91.9%). Injuries were largely caused by thermal burns (99.2%). Half of the children sustained injury to one body area (51.4%), while every third sufferer (37.9%) was affected by burns to body parts prone to trigger shock. Burns up to 5% of the Total Body Surface Area (TBSA) were suffered by half (51.2%) of the children. Most of the patients underwent conservative treatment (89.4%). CONCLUSIONS: Burns were mostly suffered by children at 1-2 years of age, with boys prevailing over girls. Injuries were largely suffered at the child's family home, in the afternoon or evening, while the child was in the care of the parents. Scalds, caused by hot liquid, constituted the most frequent type of injury. The most numerous group of affected children comprised burns to limb areas, and thorax with limbs, with the TBSA of up to 5%. The great majority of the patients underwent conservative treatment, with a hospitalization period of up to 3 days. PMID- 29575883 TI - Relationships between bone mineral density and new indices of body composition in young, sedentary men and women. AB - INTRODUCTION: Data concerning the relationship between body fat and BMD are equivocal since both positive and negative effects have been noted. Recently, the index of fat mass (IFM) representing subjects with different body fat and similar lean mass and index of lean mass (ILM) representing subjects with different lean body mass and similar body fat, have been used to evaluate body composition effect on BMD in middle-aged women. This study aimed at determination of ILM and IFM association with BMD in young men and women. MATERIAL AND METHODS: A total of 212 university students of Public Health (125 women and 87 men) participated in the study. Body composition was determined by the bioelectrical impedance method (BIA) using BC 418 MA equipment (Tanita Co., Japan). Fat mass and fat free mass were used to calculate ILM and IFM. Bone mineral density was measured on the wrist of the non-dominant hand using the DEXA method and EXA 3000 equipment (HFS Ltd., Korea). BMD was evaluated using Z-score, with values lower than -2.0 indicating inadequate BMD for subject chronological age. RESULTS: Exclusively in women, IFM was markedly and positively correlated with Z-score (r=0.366, P<0.001). In both genders, a significant relationship was found between ILM and Z scores (r=0.420; p<0.001 and r=0.220; p<0.02 in men and women, respectively). Women with lower than median IFM but similar ILM, were characterized by significantly lower Z-scores vs. women with higher IFM (-1.016 vs. -0.512; p<0.001). Irrespective of gender, participants with higher ILM but similar IFM, were characterized by markedly higher Z-score vs. their counterparts with low ILM. CONCLUSIONS: The use of IFM and ILM in the present study, allowed the observation that in young adults lean body mass was associated with BMD, regardless of gender, while fat mass is significant for bone mineral density only in women. PMID- 29575884 TI - Responsiveness of people with moderate and significant intellectual disability to physical stimulation. AB - OBJECTIVE: The aim of the research was to verify whether intellectually disabled people are responsive to motor stimulation, and whether the specific physical exercises, besides traditional rehabilitation and occupational therapy, would result in physical fitness enhancement. MATERIAL AND METHODS: The research was carried out on 259 persons with moderate and significant intellectual disability, participants of occupational therapy workshops. They were divided into two groups: a control group that underwent traditional rehabilitation treatment and occupational therapy, and an experimental group that additionally performed feasible physical exercises for 10 months. Participants' body mass and height were measured to calculate their body mass index (BMI). Physical fitness was assessed with the Eurofit Special test and additional balance tests, at the beginning and at the end of the experiment. RESULTS: The results showed that the body mass of both men and women increased in the control group, and was reduced in the experimental group. The results of the physical fitness tests were more varied, in which the control group obtained similar results in the repeated measurements, and the experimental group significantly improved the initial results after 10 months of performing the feasible physical exercises. CONCLUSIONS: The applied physical exercises performed in the experimental group were effective because they caused body mass loss and significant improvement in physical fitness. PMID- 29575885 TI - Periodontal condition in patients of the specialist Outpatient Clinics at the Institute of Rural Health in Lublin, Poland. AB - INTRODUCTION: Periodontal disease is a chronic inflammation which, if remains untreated, can lead to the loss of teeth and supporting structures. Evidence data support the relationship of periodontal disease with the development and course of diseases such as heart attack, stroke, hypertension, chronic renal diseases, rheumatoid arthritis or diabetes. OBJECTIVE: The aim of the study was to conduct an assessment of periodontal status and periodontal needs in people from the rural environment who were patients of selected specialist outpatient clinics at the Institute of Rural Health in Lublin, Poland. MATERIAL AND METHODS: The examined population included 450 patients. The Community Periodontal Index of Treatment Needs, which is a measure of the assessment of the selected periodontal symptoms incidence, was used. The obtained data was discussed and analyzed with Chi-square test. RESULTS: The data obtained revealed that a healthy periodontium occurred only in 5.1% of respondents, tartar in 41.6%, pathological pockets of 3.5-5.5 mm in 23.6%, and pockets deeper than 5.5 mm in 5.8% of patients. Most people with healthy periodontium were in the youngest age group. In the analyzed group, 7.1% of patients required specialized comprehensive periodontal treatment, and only 6.5% of the examined persons did not show any need for periodontal treatment. CONCLUSIONS: Patients of specialist clinics of the Institute of Rural Health who formed the analyzed group, had affected periodontium which required comprehensive periodontal treatment. The alarmingly high percentage of people over 55 years of age with advanced periodontopathy may translate into an increased risk of cause-and-effect incidence of systemic diseases. PMID- 29575886 TI - Health inequalities among students of lower secondary schools in Bytom, Poland. AB - INTRODUCTION AND OBJECTIVE: Poverty and low level of education pose the biggest threats to public health. Moreover, they generate inequalities in public healthThe aim of the study was to check if there are any inequalities in health among teenagers living in Bytom, Poland. MATERIAL AND METHODS: In 2011 and 2012, an epidemiological cross-sectional study was conducted on 1,099 students from lower secondary schools from Bytom. The students completed a questionnaire which was based on an earlier Health Behaviour in School-aged Children study (HBSC). Socio-Economic Status of teenagers (SES) was determined according to the Family Affluence Scale (FAS), the intensity of possible problems in the place of residence and on parents' education. Impact of SES on health self-assessment, asthma, pneumonia, bronchitis with addition to spinal deformities were also investigated. RESULTS: A good or very good level of health was declared by students from families representing a high level of FAS and residing in a more peaceful, less troubled neighbourhood. The highest level of asthma prevalence (10.9%) occurred among students from families with a low level of FAS. The students from families with high FAS were less affected by spinal deformities (34.6%). Students living in a troubled neighbourhood more often suffered from bronchial asthma, pneumonia, bronchitis and spinal deformities. CONCLUSIONS: The level of family affluence depends on the parents' education and all the analysed health problems occurred more frequently in children whose parents had completed at least general secondary education. A high economic standard of living and a peaceful neighbourhood determined good or very good health self-assessment among the surveyed students. PMID- 29575887 TI - Alcohol intoxication among adolescents and children in urban and rural environments - a retrospective analysis. AB - INTRODUCTION AND OBJECTIVE: Drinking alcohol by adolescents and children poses a risk of long-term psychological and sociological consequences, often leading to addiction in adulthood. A steady increase in the number of young people reaching for alcohol is worrying. The study analyzes the age and gender of the children, concentration of alcohol in the blood, depending on the origin of the youth (urban or rural). MATERIAL AND METHODS: The study was a retrospective analysis of 402 patients hospitalized due to alcohol intoxication in the Department of Paediatrics at Medical University in Lublin, Poland between 2004 - 2013. RESULTS: During the study period a continuous increase in admissions of patients after alcohol consumption was observed: from 27 children in 2004 to 53 in 2012 and 2013. The youngest patient hospitalized after drinking was 7.6 years old and came from the rural environment, the oldest 18 years old and came from the urban environment. In 2004 - 2007, boys dominated among children intoxicated with alcohol; since 2008, a slight prevalence of girls has been observed, especially in the urban environment. Among patients coming from the country, boys always predominated. In the study period there was noted a similar number of children consuming alcohol from rural and urban environments. CONCLUSIONS: The results suggest the need to introduce appropriate educational programmes in schools to prevent the consumption of alcohol at a young age. PMID- 29575888 TI - Encapsulation of OZ439 into Nanoparticles for Supersaturated Drug Release in Oral Malaria Therapy. AB - Malaria poses a major burden on human health and is becoming increasingly difficult to treat due to the development of antimalarial drug resistance. The resistance issue is further exacerbated by a lack of patient adherence to multi day dosing regimens. This situation motivates the development of new antimalarial treatments that are less susceptible to the development of resistance. We have applied Flash NanoPrecipitation (FNP), a polymer-directed self-assembly process, to form stable, water-dispersible nanoparticles (NPs) of 50-400 nm in size containing OZ439, a poorly orally bioavailable but promising candidate for single dose malaria treatment developed by Medicines for Malaria Venture (MMV). During the FNP process, a hydrophobic OZ439 oleate ion paired complex was formed and was encapsulated into NPs. Lyophilization conditions for the NP suspension were optimized to produce a dry powder. The in vitro release rates of OZ439 encapsulated in this powder were determined in biorelevant media and compared with the release rates of the unencapsulated drug. The OZ439 NPs exhibit a sustained release profile and several-fold higher release concentrations compared to that of the unencapsulated drug. In addition, XRD suggests the drug was stabilized into an amorphous form within the NPs, which may explain the improvement in dissolution kinetics. Formulating OZ439 into NPs in this way may be an important step toward developing a single-dose oral malaria therapeutic, and offers the possibility of reducing the amount of drug required per patient, lowering delivery costs, and improving dosing compliance. PMID- 29575889 TI - Layered Halide Double Perovskites: Dimensional Reduction of Cs2AgBiBr6. AB - We investigate the consequences of dimensional confinement on halide double perovskites by synthesizing two-dimensional analogues of the recently reported three-dimensional double perovskite Cs2AgBiBr6. The layered perovskites (BA)4AgBiBr8 (1) and (BA)2CsAgBiBr7 (2) (BA = CH3(CH2)3NH3+) feature metal-halide sheets of mono and bilayer thickness, respectively, where the ordered double perovskite lattice is partitioned by organic cations. Electronic structure calculations indicate that the indirect bandgap of Cs2AgBiBr6 becomes direct when the infinitely thick inorganic lattice is reduced to monolayer thickness. Calculations on model systems allow us to separate the effects of dimensional reduction from those of the accompanying structural distortions in the inorganic sublattice. Detailed optical characterization shows that the photophysical properties of 1 and 2 are markedly different than those of their well-studied lead-halide analogs. Hybrid layered derivatives of double perovskites substantially expand on the substitutional flexibility of halide perovskites to encompass greater compositional and electronic diversity. PMID- 29575890 TI - Molecular Oxygen Formation in Interstellar Ices Does Not Require Tunneling. AB - The formation of molecular oxygen in and on amorphous ice in the interstellar medium requires oxygen diffusion to take place. Recent experiments suggest that this process involves quantum tunneling of the oxygen atoms at sufficiently low temperatures. Fitting experimental diffusion rates between 6 and 25 K to an expression that accounts for the roughness of the surface yields excellent agreement. The molecular dynamics of adsorbed oxygen is characterized by rapid intrasite dynamics, followed by intersite transitions over distances of ~10 A. Explicit simulations using a realistic free-energy surface for oxygen diffusion on amorphous ice down to 10 K show that quantum tunneling is not required for mobility of adsorbed oxygen. This is confirmed by comparing quantum and classical simulations using the same free-energy surface. The ratio of diffusional and desorption energy Edif/ Edes = 275/1082 ~ 0.3 is at the lower end of typically used values but is still consistent with the assumptions made in models for interstellar chemistry. PMID- 29575891 TI - A New Anisotropic Dirac Cone Material: A B2S Honeycomb Monolayer. AB - Different from the isotropic Dirac cones existing in other two-dimensional (2D) materials, anisotropic Dirac cones have the merit of anisotropic carrier mobility for applications in direction-dependent quantum devices. Motivated by the recent experimental finding of an anisotropic Dirac cone in borophene, here we report a new 2D anisotropic Dirac cone material, B2S monolayer, identified by using a global structure search method and first-principles calculation combined with a tight-binding model. The B2S monolayer is found to be stable mechanically, thermally, and dynamically and exhibits an anisotropic Dirac cone exactly at the Fermi level, showing a Fermi velocity of 106 m/s in the same order of magnitude as that of graphene. Moreover, B2S monolayer is the first anisotropy Dirac cone material with a pristine honeycomb structure stabilized by S in free-standing conditions where each atom has four valence electrons on average being isoelectronic to C. This study would expand the Dirac cone material family with new features. PMID- 29575892 TI - Hidden Gratings in Holographic Liquid Crystal Polymer-Dispersed Liquid Crystal Films. AB - Dynamic diffraction gratings that are hidden in the field-off state are fabricated utilizing a room-temperature photocurable liquid crystal (LC) monomer and nematic LC (NLC) using holographic photopolymerization techniques. These holographic LC polymer-dispersed LCs (HLCPDLCs) are hidden because of the refractive index matching between the LC polymer and the NLC regions in the as formed state (no E-field applied). Application of a moderate E-field (5 V/MUm) generates a refractive index mismatch because of the NLC reorientation (along the E-field) generating high-diffraction efficiency transmission gratings. These dynamic gratings are characterized by morphological, optical, and electrooptical techniques. They exhibit a morphology made of oriented LC polymer regions (containing residual NLC) alternating with a two-phase region of an NLC and LC polymer. Unlike classic holographic polymer-dispersed LC gratings formed with a nonmesogenic monomer, there is index matching between the as-formed alternating regions of the grating. These HLCPDLCs exhibit broad band and high diffraction efficiency (~90%) at the Bragg angle, are transparent to white light across the visible range because of the refractive index matching, and exhibit fast response times (1 ms). The ability of HLCPDLCs not to consume electrical power in the off state opens new possibilities for the realization of energy-efficient switchable photonic devices.

AB - Grain-batch variation in xylanase-inhibitor levels may account for variations in the efficacy of feed xylanase supplementation. This would make inhibition an important quality parameter in the routine analysis of feedstuffs. Two analytical procedures for testing feedstuffs against specific xylanases were researched: the high-throughput viscosity-pressure assay (ViPr) and the extraction-free remazol brilliant-blue-beechwood-xylan (RBBX) assay. Thirty-two wheat cultivars were analyzed for inhibition of a commercial xylanase, Ronozyme WX. Four cultivars were selected for a feeding experiment in which the growth of 1440 broilers from ages 7-33 days was monitored. The treatments resulted up to 7 % difference (day 14) in broiler weight . The cultivar choice had an effect throughout the experiment ( p < 0.05). The performance ranking of the treatments corresponded better to xylanase inhibition than to crude-protein content or nonstarch polysaccharide content. Wheat-grain xylanase-inhibitor content is therefore a highly relevant quality parameter when broiler diets are supplemented with feed xylanase.

AB - Carborane cage chirality is an outstanding issue of great interest as the icosahedral carboranes have wide applications in medicinal and materials chemistry. The synthesis of optically active carborane derivatives, whose chirality is associated with the substitution patterns on the polyhedron, will open new avenues to carborane chemistry. We report herein an efficient method to achieve chiral-at-cage arylation of o-carboranes with high regio- and enantioselectivities by a strategy of palladium-catalyzed asymmetric intramolecular B-H arylation and cyclization. This represents the first example of the enantioselective reaction on carboranes, providing an efficient way for the construction of chiral-at-cage compounds with new skeletons.

In this study, key volatile compounds in this traditional Polish meat product were determined using gas chromatography-olfactometry and aroma extract dilution analysis (AEDA). In total, 27 odor-active volatile compounds were identified, with flavor dilution (FD) factors ranging from 4 to 1024, with the highest FD factors noted for 2-methoxyphenol, 2-methoxy-4-(prop-2-enyl)phenol, and 2-methoxy 4-( E)-(prop-1-en-1-yl)phenol. Results of the quantitative analyses based on determinations with stable isotope dilution assays (SIDAs) and standard addition (SA), followed by calculations of the odor activity value (OAV), enabled identifying 24 of the volatile compounds responsible for flavor development in the analyzed smoked cooked loin. The highest OAVs were obtained for 2 methoxyphenol, 2-methyl-3-furanthiol, 1-octen-3-one, and 2-methyl-3 (methyldithio)furan. PMID- 29575896 TI - Free-Energy Landscape of the Dissolution of Gibbsite at High pH. AB - The individual elementary reactions involved in the dissolution of a solid into solution remain mostly speculative due to a lack of direct experimental probes. In this regard, we have applied atomistic simulations to map the free-energy landscape of the dissolution of gibbsite from a step edge as a model of metal hydroxide dissolution. The overall reaction combines kink formation and kink propagation. Two individual reactions were found to be rate-limiting for kink formation, that is, the displacement of Al from a step site to a ledge adatom site and its detachment from ledge/terrace adatom sites into the solution. As a result, a pool of mobile and labile adsorbed species, or adatoms, exists before the release of Al into solution. Because of the quasi-hexagonal symmetry of gibbsite, kink site propagation can occur in multiple directions. Overall, our results will enable the development of microscopic mechanistic models of metal oxide dissolution. PMID- 29575897 TI - Directional Transport of a Liquid Drop between Parallel-Nonparallel Combinative Plates. AB - Liquids confined between two parallel plates can perform the function of transmission, support, or lubrication in many practical applications, due to which to maintain liquids stable within their working area is very important. However, instabilities may lead to the formation of leaking drops outside the bulk liquid, thus it is necessary to transport the detached drops back without overstepping the working area and causing destructive leakage to the system. In this study, we report a novel and facile method to solve this problem by introducing the wedgelike geometry into the parallel gap to form a parallel nonparallel combinative construction. Transport performances of this structure were investigated. The criterion for self-propelled motion was established, which seemed more difficult to meet than that in the nonparallel gap. Then, we performed a more detailed investigation into the drop dynamics under squeezing and relaxing modes because the drops can surely return in hydrophilic combinative gaps, whereas uncertainties arose in gaps with a weak hydrophobic character. Therefore, through exploration of the transition mechanism of the drop motion state, a crucial factor named turning point was discovered and supposed to be directly related to the final state of the drops. On the basis of the theoretical model of turning point, the criterion to identify whether a liquid drop returns to the parallel part under squeezing and relaxing modes was achieved. These criteria can provide guidance on parameter selection and structural optimization for the combinative gap, so that the destructive leakage in practical productions can be avoided. PMID- 29575898 TI - Hydride Conformers of the Nitrogenase FeMo-cofactor Two-Electron Reduced State E2(2H), Assigned Using Cryogenic Intra Electron Paramagnetic Resonance Cavity Photolysis. AB - Early studies in which nitrogenase was freeze-trapped during enzymatic turnover revealed the presence of high-spin ( S = 3/2) electron paramagnetic resonance (EPR) signals from the active-site FeMo-cofactor (FeMo-co) in electron-reduced intermediates of the MoFe protein. Historically denoted as 1b and 1c, each of the signals is describable as a fictitious spin system, S' = 1/2, with anisotropic g' tensor, 1b with g' = [4.21, 3.76, ?] and 1c with g' = [4.69, ~3.20, ?]. A clear discrepancy between the magnetic properties of 1b and 1c and the kinetic analysis of their appearance during pre-steady-state turnover left their identities in doubt, however. We subsequently associated 1b with the state having accumulated 2[e-/H+], denoted as E2(2H), and suggested that the reducing equivalents are stored on the catalytic FeMo-co cluster as an iron hydride, likely an [Fe-H-Fe] hydride bridge. Intra-EPR cavity photolysis (450 nm; temperature-independent from 4 to 12 K) of the E2(2H)/1b state now corroborates the identification of this state as storing two reducing equivalents as a hydride. Photolysis converts E2(2H)/1b to a state with the same EPR spectrum, and thus the same cofactor structure as pre-steady-state turnover 1c, but with a different active-site environment. Upon annealing of the photogenerated state at temperature T = 145 K, it relaxes back to E2(2H)/1b. This implies that the 1c signal comes from an E2(2H) hydride isomer of E2(2H)/1b that stores its two reducing equivalents either as a hydride bridge between a different pair of iron atoms or an Fe-H terminal hydride. PMID- 29575899 TI - Sequential Hybrid Three-Dimensional Gas Chromatography with Accurate Mass Spectrometry: A Novel Tool for High-Resolution Characterization of Multicomponent Samples. AB - A novel sequential three-dimensional gas chromatography-high-resolution time-of flight mass spectrometry (3D GC-accTOFMS) approach for profiling secondary metabolites in complex plant extracts is described. This integrated system incorporates a nonpolar first-dimension (1Dnp) separation step, prior to a microfluidic heart-cut (H/C) of a targeted region(s) to a cryogenic trapping device, directly followed by the rapid reinjection of a trapped solute into a polar second-dimension (2DPEG) column for multidimensional separation (GCnp GCPEG). For additional separation, the effluent from 2DPEG can then be modulated according to a comprehensive 2D GC process (GC*GC), using an ionic liquid phase as a third-dimension (3DIL) column, to produce a sequential GCnp-GCPEG*GCIL separation. Thus, the unresolved or poorly resolved components, or regions that require further separation, can be precisely selected and rapidly transferred for additional separation on 2D or 3D columns, based on the greater separation realized by these steps. The described integrated system can be used in a number of modes, but one useful approach is to target specific classes of compounds for improved resolution. This is demonstrated through the separation and detection of the oxygenated sesquiterpenes in hop ( Humulus lupulus L.) essential oil and agarwood ( Aquilaria malaccensis) oleoresin. Improved resolution and peak capacity were illustrated through the progressive comparison of the tentatively identified components for GCnp-GCPEG and GCnp-GCPEG*GCIL methods. Relative standard deviations of intraday retentions (1 tR, 2 tR,, and 3 tR) and peak areas of <=0.01, 0.07, 0.71, and 7.5% were achieved. This analytical approach comprising three GC column selectivities, hyphenated with high-resolution TOFMS detection, should be a valuable adjunct for the improved characterization of complex plant samples, particularly in the area of plant metabolomics. PMID- 29575900 TI - Critical Factors in Determining the Heterolytic versus Homolytic Bond Cleavage of Terminal Oxidants by Iron(III) Porphyrin Complexes. AB - Heterolytic versus homolytic cleavage of the metal-bound terminal oxidant is the key for determining the nature of reactive intermediates in metalloenzymes and metal catalyzed oxygenation reactions. Here, we study the bond cleavage process of hypochlorite by iron(III) porphyrin complexes having 4-methoxy-2,6 dimethylphenyl (1), 2,4,6-trimethylphenyl (2), 4-fluoro-2,6-dimethylphenyl (3), 2 chloro-6-methylphenyl (4), 2,6-dichlorophenyl (5), and 2,4,6-trichlorophenyl (6) groups at the meso position. Oxoiron(IV) porphyrin pi-cation radical complexes (CompI) are characterized from the reactions of 1-4 with tetra- n-butylammonium hypochlorite (TBA-OCl) in dichloromethane at -80 degrees C, while oxoiron(IV) porphyrin complexes (CompII) are characterized for 5 and 6 under the same conditions. For all of 1-6, we find the formation of an epoxidation product in good yields from the catalytic reactions with TBA-OCl, suggesting heterolytic cleavages of the O-Cl bonds. CompI of 5 and 6 are reduced to the corresponding CompII by both chloride and hypochlorite, while CompI of 1-4 are not. The reduction reactions with hypochlorite are much faster than those with chloride. These results provide a mechanism where the O-Cl bond of the iron-bound hypochlorite is cleaved heterolytically to form CompI for all of 1-6, but the subsequent reduction reaction with remaining hypochlorite affords CompII for 5 and 6. The E(OCl*/OCl-) value is the boundary to discriminate the identity of the final product: CompI or CompII. Thermodynamic analysis based on the redox potential is successfully applied for explaining the bond cleavage processes of the hypochlorite, hydroperoxide, and tert-butyl peroxide complexes.

AB - Recent research has shown that the biosynthesis of several key odorants is controlled by genes whose expression is altered or even induced by biotic or abiotic stress. These new findings provide a roadmap for improvement of flavor quality by the application of moderate, well-controlled stress. This strategy aims at reducing the flavor deficiencies in modern commercial varieties as a "green" alternative to genetic engineering. The workflow for a successful implementation of this approach, from the identification of key odorants by molecular science techniques to the investigation of mechanisms controlling their biosynthesis, is complex and calls for interdisciplinary research.

AB - The objective of this feature article is to coalesce our recent advancements on different expressions of tailor-made supramolecular self-assemblies and to explore them as a function of molecular architecture. In the last decade, we have developed a library of elegant and simple functional amphiphilic small molecules, which have very interesting abilities to form diverse manifestations of supramolecular self-assemblies such as micelles, reverse micelles, vesicles, fibers, supramolecular gels, and so on. Each of the expressions of the self aggregated structures has its individual prominence and finds important applications in the fields of chemistry, physics, biology, and others. In this feature article, the major emphasis is mostly on how to attain precise control over the development of various well-defined supramolecular self-assemblies through the judicious design of low-molecular-weight amphiphiles. By tuning only the functional moieties of the amphiphilic structure, diverse supramolecular architectures can be constructed with task-specific applications. We expect that this article will provide a general and conceptual demonstration of various approaches to the development of different functional supramolecular systems and their prospective applications in numerous domains. PMID- 29575903 TI - Selective Enrichment and Direct Analysis of Protein S-Palmitoylation Sites. AB - S-Fatty-acylation is the covalent attachment of long chain fatty acids, predominately palmitate (C16:0, S-palmitoylation), to cysteine (Cys) residues via a thioester linkage on proteins. This post-translational and reversible lipid modification regulates protein function and localization in eukaryotes and is important in mammalian physiology and human diseases. While chemical labeling methods have improved the detection and enrichment of S-fatty-acylated proteins, mapping sites of modification and characterizing the endogenously attached fatty acids are still challenging. Here, we describe the integration and optimization of fatty acid chemical reporter labeling with hydroxylamine-mediated enrichment of S-fatty-acylated proteins and direct tagging of modified Cys residues to selectively map lipid modification sites. This afforded improved enrichment and direct identification of many protein S-fatty-acylation sites compared to previously described methods. Notably, we directly identified the S-fatty acylation sites of IFITM3, an important interferon-stimulated inhibitor of virus entry, and we further demonstrated that the highly conserved Cys residues are primarily modified by palmitic acid. The methods described here should facilitate the direct analysis of protein S-fatty-acylation sites and their endogenously attached fatty acids in diverse cell types and activation states important for mammalian physiology and diseases. PMID- 29575904 TI - Degradation Chemistry and Stabilization of Exfoliated Few-Layer Black Phosphorus in Water. AB - Exfoliated black phosphorus (BP), as a monolayer or few-layer material, has attracted tremendous attention owing to its unique physical properties for applications ranging from optoelectronics to photocatalytic hydrogen production. Approaching intrinsic properties has been, however, challenged by chemical reactions and structure degradation of BP under ambient conditions. Surface passivation by capping agents has been proposed to extend the processing time window, yet contamination or structure damage rise challenges for BP applications. Here, we report experiments combined with first-principle calculations that address the degradation chemistry of BP. Our results show that BP reacts with oxygen in water even without light illumination. The reaction follows a pseudo-first-order parallel reaction kinetics, produces PO23-, PO33-, and PO43- with reaction rate constants of 0.019, 0.034, and 0.023 per day, respectively, and occurs preferentially from the P atoms locating at BP edges, which yields structural decay from the nanoflake edges in water. In addition, a negligible decay ratio (0.9 +/- 0.3 mol %) and preserved photocatalytic activity of BP are observed after storage in deoxygenated water for 15 days without surface passivation under ambient light. Our results reveal the chemistry of BP degradation and provide a practical approach for exfoliation, delivery, and application of BP.

AB - We reported a simple genome editing approach that can generate human immunodeficiency virus-1 (HIV) coreceptor defective cells, which may be useful for latent viral eradication treatment. Samples of bone marrow leftover after diagnostic procedures and crude bone marrow from aviremic HIV patients were subjected to zinc finger nuclease-mediated stop codon insertion into chemokine receptor 5 (CCR5) loci. Locked nucleic acid-based polymerase chain reaction was used to estimate the amount of insertion in the expandable CD34+ cells. The results showed that about 0.5% of CD34+ cells carried stop codon insertions in CCR5 loci. Cells edited using this simple protocol have the potential to be infused back into the bone marrow.

AB - BACKGROUND/RATIONALE: This study tested the psychometric properties of the Quality of Life in Late-Stage Dementia (QUALID) Scale using Rasch analysis. The QUALID includes 11 items with a 5-point response scale. Scores range from 11 to 55, and lower scores indicate higher quality of life (QoL). METHODS: Baseline data from a randomized clinical trial including 137 residents from 14 nursing homes were used. Psychometric testing included item mapping, evaluation of response categories, item reliability, construct validity based on INFIT and OUTFIT statistics, and convergent validity based on correlations between QoL and pain, agitation, depression, and function. RESULTS: The Cronbach alpha was .89. All the items except "appears physically uncomfortable" fit the model. There was a significant relationship between QoL and depressive symptoms ( r = .71, P = .001), pain ( r = .26, P = .01), physical function ( r = -.19, P = .03), and agitation ( r = .56, P = .001). The categories were appropriately used. Item mapping suggested a need for easier items.

AB - AIM: To comprehensively evaluate the diagnostic value of serum matrix metalloproteinase-9 (MMP-9) level for colorectal cancer (CRC). METHODS: Both of the relationships between MMP-9 level and CRC and the diagnostic value were evaluated from 12 eligible papers. RESULTS: The high MMP-9 level increased CRC risk. The estimated sensitivity and specificity were 69 and 68%, respectively, which signified that the diagnostic value was medium. Diagnostic odds ratio and the area under the receiver operating characteristic curve suggested MMP-9 level has a moderate diagnostic value in CRC. Additionally, the likelihood matrix indicated MMP-9 levels could be considered as a biomarker for the diagnosis of CRC. CONCLUSION: Patients with CRC have elevated MMP-9 levels, which is a potential biomarker for CRC diagnosis.

AB - Second-line therapy randomized trials with lopinavir/ritonavir question the value of resistance testing to guide nucleoside reverse transcriptase inhibitor (NRTI) selection. In this study, we investigated the association between baseline drug resistance and treatment outcome after 104 weeks of second-line therapy with NRTIs and either darunavir/ritonavir or lopinavir/ritonavir in West-central Africa. We did an observational analysis of data from 387 individuals in a randomized, open-label 2LADY trial in Burkina Faso, Cameroon, and Senegal. We modeled the association between RTI drug resistance mutations (DRMs) and virological failure (VF) (viral load [VL] <50 copies/mL) at week 104 using logistic regressions. Covariates included baseline VL and CD4+ count, demographic, and adherence data. Overall, 193 (49.9%), 150 (38.8%), and 44 (11.4%) individuals had, respectively, low/none (genotypic susceptibility score [GSS] <1), intermediate (GSS = 1), and high predicted NRTI activity (GSS >1) in their prescribed second-line regimen. The average number of DRMs by drug class, the proportion of individuals by GSS category, and the duration of first-line therapy were not associated with VF (p > .05). High VL at switch was the only consistent prognostic factor for VF after multivariate adjustment (p < .01). Suboptimal adherence, high predicted RTI activity, or low NRTI mutations were associated with VF (p < .05) when using higher end points for VF or in the intention-to-treat analysis. In conclusion, the use of RTIs with predicted reduced activity does not impair second-line protease inhibitor-based therapy. Therefore, HIV care in resource-limited settings should prioritize strategies to improve adherence and targeted VL testing over drug resistance testing for selecting NRTIs during a protease-based second-line switch.

AB - HIV-1 group N (HIV-1/N) remains rare and mainly restricted to Cameroon. In this study, we report a new HIV-1/N infected case identified during routine HIV screening activities in Yaounde. The genetic characterization of the near full length genome of this virus strain revealed that it is genetically distinct to all HIV-1/N described to date. However, the Vpu protein responsible for tetherin antagonism displayed the same amino acid substitutions (E15A, V19A, I25L, and V26L) as other HIV-1/N from Cameroon. PMID- 29575911 TI - T-2 mycotoxin treatment of newborn rat pups does not significantly affect nervous system functions in adulthood. AB - T-2 toxin is primarily produced by Fusarium sp. abundant under temperate climatic conditions. Its main harmful effect is the inhibition of protein synthesis. Causing oxidative stress, it also promotes lipid peroxidation and changes plasma membrane phospholipid composition; this may lead to nervous system alterations. The aim of the present study was to examine whether a single dose of T-2 toxin administered at newborn age has any long-lasting effects on nervous system functions. Rat pups were treated on the first postnatal day with a single intraperitoneal dose of T-2 toxin (0.2 mg/bwkg). Body weight of treated pups was lower during the second and third week of life, compared to littermates; later, weight gain was recovered. At young adulthood, behavior was tested in the open field, and no difference was observed between treated and control rats. Field potential recordings from somatosensory cortex and hippocampus slices did not reveal any significant difference in neuronal network functions. In case of neocortical field EPSP, the shape was slightly different in treated pups. Long term synaptic plasticity was also comparable in both groups. Seizure susceptibility of the slices was not different, either. In conclusion, T-2 toxin did not significantly affect basic nervous system functions at this dose. PMID- 29575912 TI - Intrathalamic connections shape spindle activity - a modelling study. AB - Spindle oscillations are generated predominantly during sleep state II, through cyclical interactions between thalamocortical and reticular neurons. Inhibition from reticular cells is critical for this activity; it enables burst firing by the de-inactivation of T-type Ca2+ channels. While the effect of different channelopathies on spindling is extensively investigated, our knowledge about the role of intrathalamic connections is limited. Therefore, we explored how the connection pattern and the density of reticular inhibitory synapses affect spindle activity in a thalamic network model. With more intrareticular connections, synchronous firing of reticular cells, and intraspindle burst frequency decreased, spindles lengthened. In models with strong intrareticular inhibition spindle activity was impaired, and a sustained 6-8 Hz oscillation was generated instead. The strength of reticular innervation onto thalamocortical cells played a key role in the generation of oscillations; it determined the amount of thalamocortical cell bursts, and consequently spindle length. Focal inputs supported bursts but affected only a few cells thus barely reinforced network activity, while diffuse contacts aided bursts only when a sufficient number of reticular cells fired synchronously. According to our study, alterations in the connection pattern influence thalamic activities and may contribute to pathological conditions, or alternatively, they serve as a compensatory mechanism. PMID- 29575913 TI - Age-related and function-dependent regional alterations of free L- and D aspartate in postembryonic chick brain. AB - D-aspartate (D-Asp) modulates adult neural plasticity and embryonic brain development by promoting cell proliferation, survival and differentiation. Here, developmental changes of the excitatory amino acids (EAAs) L-Glu, L-Asp and D-Asp were determined during the first postembryonic days, a time window for early learning, in selected brain regions of domestic chickens after chiral separation and capillary electrophoresis. Extracellular concentration (ECC) of EAAs was measured in microdialysis samples from freely moving chicks. ECC of D-Asp (but not L-EAAs) decreased during the first week of age, with no considerable regional or learning-related variation. ECC of L-Asp and L-Glu (but not of D-Asp) were elevated in the mSt/Ac in response to a rewarding stimulus, suggesting importance of Asp-Glu co-release in synaptic plasticity of basal ganglia. Potassium-evoked release of D-Asp, with a protracted transient, was also demonstrated. D-Asp constitutes greater percentage of total aspartate in the extracellular space than in whole tissue extracts, thus the bulk of D-Asp detected in tissue appears in the extracellular space. Conversely, only a fraction of tissue L-EAAs can be detected in extracellular space. The lack of changes in tissue D-Asp following avoidance learning indicates a tonic, rather than phasic, mechanism in the neuromodulatory action of this amino acid.

AB - This research was conducted in a greenhouse to evaluate the effects of exogenous application of salicylic acid (SA) (1 mM) and 6-benzylaminopurine (BAP) (50 MUM) on physiological performance of faba bean (Vicia faba) under different levels of NaCl salinity (0, 4, 8 and 12 dS/m). The experiment was arranged as factorial on the bases of randomized complete block design in three replications. Leaf Na+ content, root and leaf soluble sugars, antioxidant enzymes activities such as catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD) and lipid peroxidation increased, but K+, K+/Na+ and membrane stability index (MSI) decreased as a result of salt stress. However, foliar sprays of BAP and particularly SA reduced Na+ content and lipid peroxidation, while enhanced the K+ content, K+/Na+, soluble sugars, antioxidant enzymes activities and MSI under different levels of salinity. It was, therefore, concluded that exogenous application of these growth regulators (GR) can considerably improve salt tolerance and physiological performance of faba bean. PMID- 29575915 TI - Transfer of egg white proteins and activation of proteases during the development of Anas platyrhynchos domestica embryo. AB - The route of egg white transfer into the yolk and the mechanisms underlying the digestion of egg proteins are unexplored in the fertilized egg of the duck, Anas platyrhynchos domestica. Here, we investigated the route(s) of egg white transfer and we determined the type of activated proteases during duck embryo development. Initially, we tested the electrophoretic patterns of egg proteins throughout development. Then, we used lysozyme as a reference protein to follow egg white transfer and we measured its activity. After that, we determined the type of activated proteases by employing different types of protease inhibitors. Several presumptive egg white protein bands appeared in different egg compartments. Also, lysozyme activity was detected chronologically on day 15 in the extraembryonic fluid, on day 17 in the amniotic and intestinal fluids and on day 19 in the yolk. Furthermore, acidic aspartic proteases seemed to be activated at hatch in the intestine and late in development in the yolk. Our results suggest that the main route of egg white transfer into the yolk is through the amniotic cavity and intestinal lumen. Also, the transferred egg white and endogenous yolk proteins are probably digested by the activated acidic proteases in the intestine and yolk. PMID- 29575916 TI - Factors affecting synonymous codon usage of housekeeping genes in Drosophila melanogaster. AB - Housekeeping genes (HK genes) are required for cell survival and the maintenance of basic cellular functions. The investigation of factors affecting codon usage patterns in HK genes of insects can help in understanding the molecular evolution of insects and aid the development of insect pest management strategies. In this study, we employed bioinformatics approaches to analyze the codon usage bias (CUB) of HK genes in the insect model organism, Drosophila melanogaster. A comparison of CUB between 1107 HK genes and 1084 high tissue specificity genes suggested that HK genes have higher CUB in D. melanogaster. In addition, we found that CUB inversely correlates with the non-synonymous substitution rate of HK genes. Therefore, we attempted to identify the factors that potentially influence the codon usage pattern of HK genes. Our results suggest that mutation pressure and natural selection highly correlate with CUB in the HK genes of D. melanogaster and that two topological properties of HK proteins (proportion of protein interacting length and protein connectivity) also correlate with CUB in the HK genes of D. melanogaster. This study provides insight into CUB in the HK genes of D. melanogaster, and the results can support future investigations of potential applications in agricultural and biomedical field.

AB - The aim of the study was to describe the morphology and the development of the extraocular muscles (EOMs) in the pre-hatchling and post-hatchling African black ostrich. The study involved 50 birds aged between 28 days and 3 years. The EOMs were analyzed morphologically with respect to the location and length of the straight and oblique muscles and the third eyelid muscles, the length and breadth of their tendons as well as the distance and shape of the muscle tendon insertions at the corneal limbus. A histological and histometric analysis were also carried out. The greatest increase in the length of the EOMs was noted in groups III-V. A marked increase in the length of the tendons of the dorsal straight muscle was found in groups II and III, in the tendons of the nasal straight muscle in groups IV and V, in the tendons of the dorsal oblique muscle in groups III to V and in the tendons of the ventral oblique muscle in groups IV and V. There was a significant increase in the breadth of the dorsal straight and ventral oblique muscle tendons in groups IV and V and the tendons of the pyramidal muscle in groups III and V. The distance of the distal insertion of the tendon at the corneal limbus increased steadily with age in all the examined groups. The number of fascicles and muscle fibres, their diameter and length in all the studied EOMs were different in the different groups.

Here, we report the identification of the smallest lectin-like peptide (odorranalectin HYba) from the skin secretion of Hydrophylax bahuvistara which is being the shortest lectin-like peptide identified so far from the frog skin secretion, with 15 amino acid residues. The peptide is the first report from an Indian frog and lacks antimicrobial activity but strongly agglutinate intact human erythrocytes. The sequences at the L-fucose recognizing region is conserved as in other lectins reported from frog skin secretion and could be exploited for specificity and drug targeting properties. PMID- 29575919 TI - Effect of silver nanoparticles on phenolic compounds production and biological activities in hairy root cultures of Cucumis anguria. AB - The present study describes the elicitor effect of silver ion (Ag+) and biologically synthesized silver nanoparticles (AgNPs) to enhance the biomass accumulation and phenolic compound production as well as biological activities (antioxidant, antimicrobial and anticancer) in genetically transformed root (hairy root) cultures of Cucumis anguria. The biomass of hairy root cultures was significantly increased by AgNPs whereas decreased in Ag+ elicitation at 1 and 2 mg/L. AgNPs-elicited hairy roots produced a significantly higher amount of individual phenolic compounds (flavonols, hydroxycinnamic and hydroxybenzoic acids), total phenolic and flavonoid contents than Ag+-elicited hairy roots. Moreover, antioxidant, antimicrobial and anticancer activities were significantly higher following AgNPs-elicitation compared with that in Ag+-elicited hairy roots. We suggest that AgNPs could be an efficient elicitor in hairy root cultures to increase the phytochemical production. PMID- 29575921 TI - TK1 overexpression is associated with the poor outcomes of lung cancer patients: a systematic review and meta-analysis. AB - AIM: The study aimed to unveil the effect of TK1 expression on the clinicopathological significance and prognosis in patients with lung cancer. Results & methodology: Studies for meta-analysis were selected according to a thorough literature search in databases (PubMed, EMBASE and Chinese databases). Ten studies containing 1393 lung cancer patients were investigated in our analysis. The TK1 overexpression was associated with poorer overall survival(OS) in lung cancer patients (hazard ratio = 1.881; 95% CI:1.318-2.684, Z = 3.48; p = 0.001). Furthermore, The TK1 expression is associated with the clinicopathological features of lung cancer patients (tumor type, age, lymph node metastasis, distant metastasis and tumor, node, metastasis [TNM] stages). Discussion & conclusion: The TK1 expression might have a supportive implication in assessing biological behavior and prognosis of lung cancer patients. PMID- 29575922 TI - Evaluation of the Area of the Lisfranc Ligament Damaged by Screw Fixation. AB - BACKGROUND: A cannulated screw is currently the standard fixation method to reduce and stabilize diastasis at the lisfranc joint following injury. Currently, there is no literature examining the area of the lisfranc ligament damaged by screw placement. The objective of this investigation is to define the area of the ligament damaged by fixation with a 3.5-mm cannulated screw. MATERIALS AND METHODS: Twelve cadaveric feet were dissected to identify the Lisfranc ligament metatarsal insertion site and origin on the medial cuneiform. A 3.5-mm cannulated screw was then passed over the course of the ligament and removed. The Lisfranc joint was then dissected to measure the dimensions of the ligament and damage from screw passage at the origin and insertion using imaging software. RESULTS: Mean injury area on the metatarsal was 3.49 mm2 and the area of injury for the cuneiform was 3.33 mm2. The mean percent of the area damaged was calculated to be 1.75% and 2.43% at the cuneiform and metatarsal, respectively. CONCLUSION: A proportionally small area of the Lisfranc ligament is disrupted following screw fixation, but the implications of this on ligament healing and outcomes remain to be elucidated. LEVELS OF EVIDENCE: Level V: Cadaveric study. PMID- 29575923 TI - Microfluidic-based screening of resveratrol and drug-loading PLA/Gelatine nano scaffold for the repair of cartilage defect. AB - Cartilage defect is common in clinical but notoriously difficult to treat for low regenerative and migratory capacity of chondrocytes. Biodegradable tissue engineering nano-scaffold with a lot of advantages has been the direction of material to repair cartilage defect in recent years. The objective of our study is to establish a biodegradable drug-loading synthetic polymer (PLA) and biopolymer (Gelatine) composite 3D nano-scaffold to support the treatment of cartilage defect. We designed a microfluidic chip-based drug-screening device to select the optimum concentration of resveratrol, which has strong protective capability for chondrocyte. Then biodegradable resveratrol-loading PLA/Gelatine 3D nano-scaffolds were fabricated and used to repair the cartilage defects. As a result, we successfully cultured primary chondrocytes and screened the appropriate concentrations of resveratrol by the microfluidic device. We also smoothly obtained superior biodegradable resveratrol-loading PLA/Gelatine 3D nano scaffolds and compared the properties and therapeutic effects of cartilage defect in rats. In summary, our microfluidic device is a simple but efficient platform for drug screening and resveratrol-loading PLA/Gelatine 3D nano-scaffolds could greatly promote the cartilage formation. It would be possible for materials and medical researchers to explore individualized pharmacotherapy and drug-loading synthetic polymer and biopolymer composite tissue engineering scaffolds for the repair of cartilage defect in future. PMID- 29575924 TI - What Can We Learn From Point-of-Care Blood Glucose Values Deleted and Repeated by Nurses? AB - BACKGROUND: Hospitals rely on point-of-care (POC) blood glucose (BG) values to guide important decisions related to insulin administration and glycemic control. Evaluation of POC BG in hospitalized patients is associated with measurement and operator errors. Based on a previous quality improvement (QI) project we introduced an option for operators to delete and repeat POC BG values suspected as erroneous. The current project evaluated our experience with deleted POC BG values over a 2-year period. METHOD: A retrospective QI project included all patients hospitalized at two regional academic medical centers in the Pacific Northwest during 2014 and 2015. Laboratory Medicine POC BG data were reviewed to evaluate all inpatient episodes of deleted and repeated POC BG. RESULTS: Inpatient operators choose to delete and repeat only 0.8% of all POC BG tests. Hypoglycemic and extreme hyperglycemic BG values are more likely to be deleted and repeated. Of initial values <40 mg/dL, 58% of deleted values (18% of all values) are errors. Of values >400 mg/dL, 40% of deleted values (5% of all values) are errors. Not all repeated POC BG values are first deleted. Optimal use of the option to delete and repeat POC BG values <40 mg/dL could decrease reported rates of severe hypoglycemia by as much as 40%. CONCLUSIONS: This project demonstrates that operators are frequently able to identify POC BG values that are measurement/operator errors. Eliminating these errors significantly reduces documented rates of severe hypoglycemia and hyperglycemia, and has the potential to improve patient safety. PMID- 29575925 TI - Standards for Medical Device Cybersecurity in 2018. PMID- 29575926 TI - Device and Method for Noninvasive Glucose Assessment. AB - BACKGROUND:: Intensive monitoring of blood glucose levels is crucial in diabetes management. This article presents a new device, the TensorTip Combo Glucometer (CoG), developed by Cnoga Medical Ltd, which enables to predict capillary tissue glucose concentration noninvasively. METHODS:: Noninvasive glucose readings usually provide irregular or disordered mathematical manifold over the measurement space. To establish a transfer function, which correctly correlates the noninvasive raw data and the actual invasive glucose level, we suggest a mathematical concept that employs a personal calibration procedure to associate glucose pattern and multiple optical signals derived from tissue response to light emission in the range of visible to IR. The traversed light is detected by a color image sensor to predict the tissue glucose concentration at the fingertip. This article presents the mathematical concept underlying the technology and the requirements for device operation. RESULTS:: The device was clinically evaluated and compared to standard invasive blood glucose monitoring devices in few medical centers and by home users. Based on consensus error grid analysis, more than 98% of the measurements of each study were in zones A (more than 81%) and B (more than 11%). Postmarketing evaluations showed high correlations comparing the CoG to other invasive reference devices. CONCLUSIONS:: The CoG device employs a unique mathematical approach to predict glucose concentrations based on multiple optical signals. The first clinical results indicate that the device may show appropriate agreement with reference methods to be used for pain-free glucose assessment in daily routine. PMID- 29575927 TI - On-treatment platelet reactivity in peripheral and coronary blood in patients undergoing primary PCI for ST-segment elevation myocardial infarction (STEMI). AB - Dual antiplatelet therapy is recommended in patients undergoing primary percutaneous coronary intervention (p-PCI) for ST-segment elevation myocardial infarction (STEMI). Pre-analytical variables may influence platelet function analysis results. Our aim was to evaluate the on-treatment platelet reactivity in peripheral artery vs coronary blood in patients with STEMI. We enrolled one hundred and nine patients who consecutively underwent p-PCI at Cardiology Unit of Padua University Hospital between June 2014 and June 2015. Before the procedure, all patients received intravenous aspirin 250 mg and either of the thienopyridines; clopidogrel 600 mg, prasugrel 60 mg or ticagrelor 180 mg. ASPI test and ADP-test using multiple electrode aggregometry (MEA) were performed in samples collected from both a peripheral artery and the culprit coronary artery. 'Low responders' were patients with an ASPI-test or ADP-test value greater than or equal to a pre-established normal range. No significant differences were observed in ASPI-test values between peripheral (19 (median) [3-49 (10-90 percentiles)] U) vs coronary (12 [1-40] U, p = .06) blood and in ADP-test (40 [14 82] U vs 33 [7-79] U, p =.68) blood. In peripheral blood, fifteen (14%) patients were 'low aspirin' and forty-one (38%) 'low thienopyridines' responders. The prevalence of 'low clopidogrel' responders was higher (45%) than prasugrel (36%) and ticagrelor (33%). Similar results were observed in coronary blood. In patients undergoing p-PCI for STEMI, MEA platelet function observed in coronary arteries was consistent with peripheral artery blood's independently of the antiplatelet drug used. The clinical significance of peripheral and coronary on aspirin/thienopyridines platelet reactivity needs further clarification. PMID- 29575928 TI - Health-Related Quality of Life and Psychological Aspects of Adults With Hemophilia in Iran. AB - Hemophilia causes bleeding that may affect patients' psychological aspects and quality of life. This study aims to evaluate the impact of psychological aspects and pain on health-related quality of life (HRQoL) in adult patients with hemophilia. This cross-sectional study was conducted on 103 patients with hemophilia. Data were collected using hemophilia-specific quality of life, Depression Anxiety Stress Scales, and pain visual analogue scales. Data were analyzed using correlation coefficients, analysis of covariance, and regression analysis. The results showed that 71.7% of patients with hemophilia experienced pain on the study day. The mean score of HRQoL of patients with hemophilia was 51.09 (standard deviation = 19.37). Moreover, 57.4%, 64.6%, and 44.6% of the patients had mild to severe depression, anxiety, and stress, respectively. In addition, a significant association was observed between HRQoL and depression, anxiety, and severity of pain. In the regression model, 48% of changes in HRQOL were explained by the study variables, with the severity of pain and depression being significant predictors. Therefore, attention should be paid to these aspects to improve patients' quality of life and psychosocial health. PMID- 29575929 TI - Short-term effect of kinesiology taping on temperature distribution at the site of application. AB - The aim of the study was to assess skin temperature after short-term kinesiology tape application. Seventy-four healthy volunteers with no history of lower back pain participated in the study. Kinesiology tape was applied in the experimental group, and Matopat Classic adhesive tape was applied in the placebo group. Study participants wore the tape for four consecutive days and were then thermographically analyzed for changes in skin temperature. Examination of skin surface temperature distribution revealed a significantly lower temperature (mean decrease, 1.3 degrees C P = .001 area1, 1.5 degrees C P = .001 area2, 1.6 P = .008 area3) immediately after kinesiology tape the removal. One hour after removal of the tape, a statistically significant increase in temperature was observed over all three areas (mean increase, 0.9 degrees C P = .025 area1, 1.0 degrees C P = .0008 area2, 1.0 P = .011 area3). In group 2, there were no statistically significant temperature changes. Based on the findings, we determined that kinesiology taping may affect skin temperature at the site of application. PMID- 29575930 TI - In response to: fewer adverse effects with a modified two-bag acetylcysteine protocol in paracetamol overdose. PMID- 29575931 TI - Development of novel biotinylated chitosan-decorated docetaxel-loaded nanocochleates for breast cancer targeting. AB - The motive of study was to develop biotinylated chitosan (BI-CHI) decorated docetaxel (DTX) loaded nanocochleates (BI-CHI-DTX-NC) to achieve controlled drug release, improve bioavailability, targeted delivery and enhanced anticancer potency with the reduced systemic toxicity of DTX. The development involved the loading of DTX to nanocochleates (DTX-NC) through conversion of dimyristoylphosphatidylglycerol-sodium (DMPG-Na) and cholesterol bearing liposome on addition of calcium ions, followed by encapsulated DTX-NC with BI-CHI (BI-CHI DTX- NC) and compared with DTX and DTX-NC. The release of DTX indicated strong pH dependence and implies strong hydrogen-bonding between nanocochleates and DTX. Formulated BI-CHI-DTX-NC demonstrated higher in-vitro anticancer activity in biotin over expressed human breast cancer MCF-7 cells. The targeting effect for the BI-CHI-DTX-NC was also demonstrated. The concentration of the drug needed for growth inhibition of 50% of cells in a designed time period (GI50) was 1.8 MUg/ml for free DTX while it was decreased by 33.34% for the DTX-NC (1.2 MUg/ml). Furthermore, the GI50 value of BI-CHI-DTX-NC was 0.2 MUg/ml, i.e. an 88.89% decrease was observed as compared to DTX solution. Moreover, bioavailability of DTX from BI-CHI-DTX-NC was increased by 10-folds with longer circulation time and slower plasma elimination with low tissue distribution as compared to DTX solution. The results indicate that the BI-CHI-DTX- NC has the potential to be applied for targeting anticancer drug delivery. PMID- 29575932 TI - ECM based injectable thermo-sensitive hydrogel on the recovery of injured cartilage induced by osteoarthritis. AB - Intra-articular injection of anti-inflammatory drugs can be a promising strategy for recovery of injured articular cartilage. We prepared a series of injectable thermo-sensitive composite hydrogels, composed of Pluronic F127, glycosaminoglycan (GAG) and bone morphogenetic protein (BMP-2), which was designed to mimic extracellular matrix (ECM). The rheological properties and dissolution rate of composite hydrogels containing chondroitin sulfate or with different hyaluronic acid molecular mass (10k, 90k, 800k) were investigated. Meanwhile, bovine serum albumin (BSA) or FITC-BSA was chosen as model drug loaded into PF/GAG hydrogels to study their sustained release behavior in vitro. The results showed that hydrogels could maintain shapes for more than 16 days and the release rate of BSA in PF/GAG composite gels was much slower than in PF127 gels, due to the affinity between BSA and GAG. Furthermore, increasing the molecular weight of hyaluronic acid correspondingly increased hydrogel dissolution rate and BSA release in the hydrogels. Subsequently, MTT experiments were performed to investigate the toxicity of the hydrogels on mouse pre-osteoblast cell MC3T3-E1. In vivo anti-inflammation results showed that PF/GAG@BMP-2 composite hydrogels had the most efficient efficacy on recovery of injured cartilage, which is induced by osteoarthritis, compared to the control groups (PF127@BMP-2 or BMP-2 saline solution). PMID- 29575933 TI - Comparison of the everolimus concentrations measured in whole blood with everolimus QMS or sirolimus CMIA. AB - Few years ago, it was proposed that everolimus blood levels could be determined with the commercially available sirolimus chemiluminescence magnetic microparticle immunoassay (CMIA). More recently, a highly specific microsphere system (QMS) has been approved by FDA for therapeutic drug monitoring in humans. Aim of the present study was to compare the results of everolimus assay performed with everolimus QMS and with sirolimus CMIA. The two methods were compared with Passing-Bablok regression and Bland-Altman plot analysis. The Passing-Bablok regression analysis showed that although the results obtained with the two techniques were significantly correlated, CMIA-measured differed from QMS measured everolimus concentrations by both a systematic and a proportional error. Specifically, at blood levels lower than 5 ng/mL CMIA were lower than QMS measured everolimus concentrations. On the opposite, at everolimus blood concentrations higher than 10 ng/mL CMIA-estimated values became progressively higher than QMS-measured everolimus concentrations. The analysis of the Bland Altman plot showed a less than optimal agreement of the two tests (5.59% of the data point outside the +/-1.96 SD interval). Moreover, the relationship between the difference between EveroQMS and EveroCMIA and their average was clearly concentration dependent with positive and negative values at concentration values lower and higher than 5 ng/mL respectively. In conclusion, our finding showed that the values of everolimus concentrations measured with sirolimus CMIA differ from those detected with the FDA-approved everolimus QMS further suggesting that sirolimus CMIA should not be used anymore for everolimus therapeutic drug monitoring. PMID- 29575934 TI - Work-family spillover and metabolic syndrome indicators: Findings from a national sample. AB - This study examines the link between negative work-family spillover and metabolic risk factors over a 9-year period. Data from two waves of the Midlife in the United States Survey were used to explore relationships between negative work family spillover and four indicators of metabolic syndrome-blood pressure, triglycerides, body mass index, and glucose levels. In a sample of full-time working men and women ( N = 630), increased negative spillover at baseline significantly predicted higher body mass index nearly a decade later, with a marginally significant effect for triglyceride levels. Increases in spillover also body mass index and glucose levels at follow-up. This study extends research tying work-life spillover to health and suggests that further investigation is needed to fully understand the long-term effects of work stress. PMID- 29575935 TI - Pathways linking family stress to youth delinquency and substance use: Exploring the mediating roles of self-efficacy and future orientation. AB - African American adolescents in poorer neighborhoods experience significant sanctions related to drug use and delinquency. Parental stress (i.e. substance use, mental distress, and incarceration) is associated with youth drug use and delinquency. We examined whether high self-esteem and positive future orientation mediated parental stress and youth substance use and delinquency. Demographic, family stress, future orientation, self-esteem, and drug use data were collected from 578 youths. Major findings indicated that self-esteem mediated the relationship between family stress and both drug use and delinquency. Future mediated the relationship between family stress and delinquency. Resiliency factors may promote positive development for low-income youth. PMID- 29575936 TI - Bilateral simultaneous primary choroidal melanomas: Treated with palladium-103 plaque radiation. AB - PURPOSE: To provide a clinical description of a case of bilateral choroidal melanoma in a patient treated with palladium-103 (103Pd) plaque brachytherapy. METHODS: An 81-year-old man presented with choroidal melanoma in both eyes. In consideration of tumor sizes and locations, treatment involved insertion of 103Pd radioactive plaque in the right eye followed by the left at an interval of 2 months. RESULTS: At 1-year follow-up, bilateral local control has been associated with apical tumor height regression, and visual acuity has been preserved (20/20 in the right eye and 20/25 in the left). Exudative subretinal fluid has resolved. There has been no metastasis. CONCLUSION: Bilateral choroidal melanomas are rare, reported to be either simultaneous or sequential as well as treatable. In this case, we were able to achieve tumor regression and preserve visual acuity in both eyes after plaque brachytherapy. PMID- 29575937 TI - BP1, a potential biomarker for breast cancer prognosis. AB - Homeobox genes are critical in tumor development. An isoform protein of DLX4 called BP1 is expressed in 80% of invasive ductal breast carcinomas. BP1 overexpression is implicated in an aggressive phenotype and poor prognosis. BP1 upregulation is associated with estrogen receptor negativity so those tumors do not respond to antiestrogens. Breast cancer is the second leading cause of death in women. BP1 could serve as both a novel prognostic biomarker for breast cancer and a therapeutic target. In this review, we address the role of BP1 protein in tumorigenesis of breast cancer and four other malignancies. A number of functions of BP1 in cancer are also discussed. PMID- 29575938 TI - Factors associated with post-treatment E. coli contamination in households practising water treatment: a study of rural Cambodia. AB - The purpose of this study was to assess factors associated with Escherichia coli (E. coli) contamination in rural households in Cambodia that have adopted household water treatment. The following factors were significantly associated (alpha < 0.05) with apparent E. coli contamination: cleaning the drinking vessel with untreated water, not drying the cup (with a cloth), accessing treated water by the use of a scoop (ref: using a tap), having more than one untreated water storage container, having an untreated water storage container that appeared dirty on the outside, and cows living within 10 m of the household. This study provides further evidence confirming previous studies reporting an association between inadequate cleanliness of water storage containers and household drinking water contamination, and identifies practical recommendations statistically associated with reduced post-treatment E. coli contamination in the household setting in rural Cambodia. PMID- 29575939 TI - Mechanism of MALAT1 preventing apoptosis of vascular endothelial cells induced by oxygen-glucose deficiency and reoxidation. AB - BACKGROUND: Cerebral ischemia/reperfusion (I/R) injury leads to cerebrovascular dysfunction characterized by endothelial cell injury or death. Metastasis associated lung adenocarcinoma transcript 1(MALAT1) has been reported to be associated with endothelial dysfunction. Our study aimed to investigate the effect of MALAT1 on vascular endothelium. METHODS: In this study, oxygen-glucose deprivation and reoxygenation (OGD-R) were used as in vitro studies to investigate the role of MALAT1 in I/R-induced apoptosis of cerebrovascular endothelial cells in an I/R injury model. Primary human brain microvascular endothelial cells were cultured on the condition of OGD-R and MALAT1 expression levels and apoptosis were measured at 6, 9, 12, 24 and 36 h after reoxygenation. The expression of MALAT1 and the apoptosis rate of cells exposed to OGD-R showed the trend of reoxygenation. The kit detected the expression of ROS and PI3K, and the change of Akt signal was detected by Western-blot. RESULTS: After OGD-R, over expression of MALAT1 lentivirus increased phosphatidylinositol 3-kinase (PI3K) activity and activation of Akt phosphorylation, while decreased apoptosis and caspase 3 activity. Moreover, these effects could be successfully eliminated by treating with a PI3K inhibitor (wortmannin). In contrast, knockdown of MALAT1 lentivirus reduced PI3K activity and Akt phosphorylation, while increased apoptosis and caspase 3 activity. Overexpression or knockdown of MALAT1 had no significant effect on that OGD-R-induced reactive oxygen species (ROS) production. CONCLUSIONS: This study first proposed that lncRNA MALAT1 can protect human cerebrovascular endothelial cells from OGD-R-induced apoptosis through a PI3K-dependent mechanism. These findings suggest that MALAT1 may be a potential new therapeutic target for brain I/R injury. PMID- 29575940 TI - A Tablet-Based Educational Tool: Toward More Comprehensive Pediatric Patient Education. AB - There is a paucity of data on the impact of mobile technology on physician-led education in the pediatric population. We performed a prospective pilot study in a pediatric diabetes clinic to evaluate the impact of tablet-based patient education. A total of 106 patients and caregivers completed postclinic surveys, 64 (60%) in the intervention group and 42 (40%) in the control group. The majority of the intervention group patients (86%) liked tablet use and felt it was better or similar (99%) to baseline. Moreover, a majority receiving tablet based education perceived an increase in diabetes knowledge (57%) compared with baseline (39%), though the difference did not reach statistical significance ( P = .059). Those who received tablet-based education felt they were educated on more diabetes-related topics. As the use of mobile technology in medicine grows, additional research is needed to compare mobile technology with traditional methods in providing education to the pediatric population. PMID- 29575941 TI - Treatment outcomes of conventional or high-dose ranibizumab for vascularized pigment epithelial detachment based on lesion subtypes. AB - INTRODUCTION:: A post hoc study was conducted to compare visual and anatomic outcomes of vascularized serous pigment epithelial detachment (Group 1) with fibrovascular pigment epithelial detachment (Group 2) due to age-related macular degeneration treated with either 0.5 or 2.0 mg ranibizumab injections. METHODS:: A prospective, randomized trial was performed with the following regimens for 12 months: (1) 0.5 mg monthly, (2) 0.5 mg monthly for 4 months followed by pro re nata injections, (3) 2.0 mg monthly, and (4) 2.0 mg monthly for 4 months followed by pro re nata injections. Primary measure was best-corrected standardized vision. Secondary measures included central subfield, thickness surface area A2, greatest linear diameter, heights of pigment epithelial detachment and choroidal neovascularization (CNV), subretinal fluid, cystoid macular edema, and adverse events. RESULTS:: For 36 eyes (8 in Group 1 and 28 in Group 2), follow-up time was 12 months. There were no differences in baseline features between groups except for pigment epithelial detachment A2 (Group 2 > Group 1). Two-way analysis of variance showed comparable improvements in anatomic and vision outcomes. Three way analysis of variance also showed similar responses for both lesion subtypes with high-dose treatment. There was a trend toward greater pigment epithelial detachment resolution in Group 1 eyes. There were no differences in retinochoroidal angiomatous proliferation (Type-3 CNV) and cataracts between groups, although greater percentages of eyes in Group 1 developed retinal pigment epithelial tears (25% vs 10.7%). CONCLUSION:: There were no differences in vision and anatomic outcomes between lesion subtypes, and similarly, more rapid responses to high-dose than conventional-dose ranibizumab occurred for eyes with both lesion subtypes. More retinal pigment epithelial tears may develop in eyes with vascularized serous pigment epithelial detachment. PMID- 29575942 TI - Effects of Plantago lanceolata L. extract on full-thickness excisional wound healing in a mouse model. AB - Wound healing requires cells that increase both collagen production as a result of inflammatory events and regeneration of epithelial tissue. The Plantago species of herbs have been used in traditional treatment of skin disorders and infectious diseases, and digestive, respiratory, reproductive and circulatory conditions. We investigated the efficacy of different concentrations of Plantago lanceolata L. extract (PLE) for wound healing owing to its anti-inflammatory, anti-bacterial, anti-fungal, anti-oxidant, anti-ulcerative, analgesic and immunomodulatory properties. We used 72 mice in four groups of 18. An excisional 1 cm wound was created in the skin on the back of the mice in all groups. An ointment containing 10% PLE was applied to the wound in group 1, an ointment containing 20% PLE was applied in group 2 and vaseline was applied in group 3. In group 4, no treatment was applied to the wound. On days 7, 14, and 21 of the experiment, six animals in each group were sacrificed after the wounds were photographed and specimens from the wound sites were examined. On day 14, epithelialization was more prominent in group 2, while vascularization and collagen deposition was more advanced in groups 1 and 2 compared to the other groups. Immunohistochemical examination revealed that TGF-beta1 expression was elevated on day 14 in all groups; however, this elevation was more limited in groups 1 and 2 than in groups 3 and 4. Although ANGPT-2 expression increased in groups 1 and 4 on day 14, it decreased significantly in groups 2 and 3. We found that different concentrations of PLE exhibited positive effects on wound healing. Application of 10% PLE ointment may be a useful strategy for wound healing. PMID- 29575943 TI - Prevalence of prenatal and postpartum depression and associated factors among HIV infected women in public primary care in rural South Africa: a longitudinal study. AB - This study aimed to assess the longitudinal prevalence of prenatal and postnatal depression and associated factors among HIV-infected women in rural South Africa. In a longitudinal, cluster-randomized, prevention of mother to child transmission (PMTCT) intervention trial, 681 HIV-infected prenatal women in 12 community health centres in Mpumalanga province, South Africa, were recruited in 2015 by consecutive sampling at 8-24 weeks pregnancy and followed up at 32 weeks prenatally, and 6 and 12 months postpartum (retention rate = 59.2%). Results indicate that at baseline, 48.7% of the women screened positive for depression (scores of >=13 on the "Edinburgh Postnatal Depression Scale 10"), while postnatally (at 12 months) the prevalence was 35.6%. Mothers who did not have depression before or after were 205 (50.1%), those who had depression before and after were 58 (14.4%), those who had depression only before were 81 (20.1%), and those who had depression only after were 59 (14.6%). In multinominal logistic regression analyses, less education and physical and psychological intimate partner violence were associated with sustained perinatal depression. Participation in the PMTCT intervention was associated with remitting depression while alcohol use was associated with the onset of postnatal depression. Using generalized linear mixed models in longitudinal analyses, psychological partner violence, lack of male involvement during pregnancy and non-adherence to antiretroviral treatment were associated with depression. In conclusion, a high pre- and postnatal prevalence of depression was found highlighting the utility of interventions to address prevention and treatment of perinatal depression. PMID- 29575944 TI - The diagnosis and management of extramammary Paget's disease. AB - INTRODUCTION: Extramammary Paget's disease (EMPD) is a rare neoplastic condition that commonly affects the anogenital area in the elderly. Owing to its low incidence, limited data regarding EMPD's diagnosis and treatment have been available. This review article aims to explore the current knowledge of EMPD to improve the management of this disease. Areas covered: This review outlines the diagnosis and management of EMPD. Articles on this issue that had been published in PubMed were identified and surveyed. We provide an overview of the reported studies, focusing on the recent advances in this field. Expert commentary: A new TNM staging system specific for EMPD has been proposed in Japan; the T category was classified by tumor thickness and lymphovascular invasion, the N category by the number of metastatic lymph nodes, and the M category by systemic metastases. As new diagnostic tools for EMPD, dermoscopy and reflectance confocal microscopy have emerged. Recent reports about Mohs micrographic surgery, mapping biopsy, radiation therapy, photodynamic therapy, topical imiquimod, conventional chemotherapy, and targeted therapy are also discussed. Despite the increasing publications of EMPD, limited information on this condition is available and the accumulation of more data is required. PMID- 29575945 TI - Current approaches to challenging scenarios in myeloproliferative neoplasms. AB - INTRODUCTION: The Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) including polycythemia vera, essential thrombocythemia and primary myelofibrosis are clonal hematological malignancies that originate at the level of the hematopoietic stem cell, and are characterized by excessive proliferation of cells belonging to one or more of the myeloid lineages. Central to the pathogenesis of the MPNs is constitutive activation of the JAK/STAT signaling pathway due to a family of driver mutations affecting JAK2, CALR or MPL. These disorders share common clinical and laboratory features, a significant burden of systemic symptoms, increased risk of developing arterial and venous thrombotic events, and the potential to progress to myelofibrosis and acute leukemia. Areas covered: We identified four clinical situations which represent challenging management dilemmas for patients with MPNs. Our conclusions and recommendations are based on a literature search using MEDLINE and recent meeting abstracts using the keywords, focusing on publications directly addressing these scenarios and on recent contributions to the field. Expert commentary: Multi-center efforts to study large cohorts of MPN patients have led to more uniform and evidence-based approaches to key aspects in MPN management. However, treatment strategies to deal with specific clinical scenarios are lacking. PMID- 29575946 TI - The use of immunotherapy for the treatment of tuberculosis. AB - INTRODUCTION: Tuberculosis (TB) is the first cause of mortality by a single infectious agent in the world, causing more than one million deaths worldwide as reported by the World Health Organization (WHO). For the optimal control of TB infection, a protective immune response that limits bacterial spread without causing damage to the host is essential. Although most healthy individuals are capable of generating protective responses, patients who suffer pulmonary TB commonly present a defective immune function. Areas covered: We intend to highlight the potential of novel immunotherapeutic strategies that enhance and promote effective immune responses. The following methodology was undertaken for establishing a literature search: the authors used PubMed to search for 'Pulmonary Tuberculosis' and keywords that denoted the novel immunotherapeutic strategies discussed in length in the text including antibodies, antimicrobial peptides, cell therapy, cytokines and gene therapy. Expert commentary: The current therapeutic regimens for this disease are complex and involve the prolonged use of multiple antibiotics with diverse side effects that lead to therapeutic failure and bacterial resistance. The standard appliance of immunotherapy and its deployment to vulnerable populations will require coordinated work and may serve as a powerful tool to combat the ensuing threat of TB. PMID- 29575947 TI - The utility of 25-question Geriatric Locomotive Function Scale for evaluating functional ability and disease activity in Japanese rheumatoid arthritis patients: A cross-sectional study using NinJa database. AB - OBJECTIVES: To investigate the distribution of 25-question Geriatric Locomotive Function Scale (GLFS-25) scores in Japanese rheumatoid arthritis (RA) patients and evaluate relationships with clinical variables. METHODS: Among 15,115 patients registered in the NinJa database for fiscal year 2015, 1710 with complete GLFS-25 and disease activity score-28 (DAS28) data were analyzed. Correlations between GLFS-25 score and clinical variables were assessed by Spearman coefficients. Mean GLFS-25 scores were compared among DAS28 groups (<2.6, 2.6-3.1, 3.2-5.0, >=5.1) using the Kruskal-Wallis test. To evaluate the performance of the GLFS-25 and Health Assessment Questionnaire Disability Index (HAQ-DI) for predicting DAS28 >= 3.2 (moderate/high disease activity), receiver operator characteristic (ROC) curves were constructed. RESULTS: GLFS-25 score was significantly correlated with age, disease duration, DAS28, and HAQ-DI. GLFS-25 score increased in parallel with DAS28. The proportion of patients with locomotive syndrome stage 2 also increased with DAS28. Area under the curve values for HAQ-DI and GLFS-25 score were 0.739 and 0.768, respectively. At a GLFS 25 positive cutoff score >=16, sensitivity was 0.716 and specificity was 0.661 for predicting DAS28 >= 3.2. CONCLUSION: This study documents the GLFS-25 score distribution in Japanese RA patients and demonstrates that GLFS-25 is a useful measure for evaluating functional ability in RA. PMID- 29575948 TI - Blood biomarkers in chronic airways diseases and their role in diagnosis and management. AB - INTRODUCTION: The complexity and heterogeneous nature of asthma and chronic obstructive pulmonary disease (COPD) results in difficulties in diagnosing and treating patients. Biomarkers that can identify underlying mechanisms, identify patient phenotypes and to predict treatment response could be of great value for adequate treatment. Areas covered: Biomarkers play an important role for the development of novel targeted therapies in airways disease. Blood biomarkers are relatively non-invasive, easy to obtain and easy to apply in routine care. Several blood biomarkers are being used to diagnose and monitor chronic airways diseases, as well as to predict response to treatment and long-term prognosis. Blood eosinophils are the best studied biomarker, the most applied in clinical practice, and until now the most promising of all blood biomarkers. Other blood biomarkers, including serum periostin, IgE and ECP and plasma fibrinogen are less studied and less relevant in clinical practice. Recent developments include the use of antibody assays of many different cytokines at the same time, and 'omics' techniques and systems medicine. Expert commentary: With the exception of blood eosinophils, the use of blood biomarkers in asthma and COPD has been rather disappointing. Future research using new technologies like big-data analysis of blood samples from real-life patient cohorts will probably gain better insight into underlying mechanisms of different disease phenotypes. Identification of specific molecular pathways and associated biomarkers will then allow the development of new targets for precision medicine. PMID- 29575949 TI - Detailed Magnetic Resonance Imaging (MRI) Analysis in Infantile Spasms. AB - PURPOSE: To evaluate initial magnetic resonance imaging (MRI) abnormalities in infantile spasms, correlate them to clinical characteristics, and describe repeat imaging findings. METHODS: A retrospective review of infantile spasm patients was conducted, classifying abnormal MRI into developmental, acquired, and nonspecific subgroups. RESULTS: MRIs were abnormal in 52 of 71 infantile spasm patients (23 developmental, 23 acquired, and 6 nonspecific) with no correlation to the clinical infantile spasm characteristics. Both developmental and acquired subgroups exhibited cortical gray and/or white matter abnormalities. Additional abnormalities of deep gray structures, brain stem, callosum, and volume loss occurred in the structural acquired subgroup. Repeat MRI showed better definition of the extent of existing malformations. CONCLUSION: In structural infantile spasms, developmental/acquired subgroups showed differences in pattern of MRI abnormalities but did not correlate with clinical characteristics. PMID- 29575950 TI - Discourses of professionalism: Metaphors, theory and practice. AB - : Professionalism is a contested concept and different discourses have differed by scope and epistemology. The theory of communicative action integrates epistemology (knowledge interests) with that of scope (lifeworld). AIM: To pragmatically inform learning of professionalism. METHODS: apply the theory of communicative action to professionalism discourses. RESULTS: Previous professionalism discourses translated into four frames: technical; communicative; improvement, and critical. These can be viewed as four metaphors the scale; conversation; consensus conference, and protest. The theory of communicative action demonstrated that a critical frame was often lacking from discussions of professionalism and emphasized critiquing the assumptions made, the way power was utilized, and the ends to which actions were directed. Using these frameworks connected discourses on professionalism to other key medical discourses particularly quality improvement, patient centeredness, social justice, and the professional well-being. CONCLUSION: The theory of communicative action adds value by introducing criteria for the evaluation of individual truth claims that expands the discussion beyond accuracy to include sincerity, ethics and coherence; and it emphasizes promoting free speech and the inclusion of diverse views and stakeholders. The theory of communicative action provides a coherent and useful framework for viewing professionalism that integrates with broader discussions about philosophy, truth claims, and post-modern society. PMID- 29575951 TI - Concurrent training protocol for men with androgen deficiency in the aging male: a randomized clinical trial. AB - BACKGROUND: The androgen deficiency in the aging male (ADAM) affects physical, sexual, and psychological aspects with characteristics symptoms of middle-aged men. The practice of regular physical activity and physical exercise can attenuate these symptoms. The aim of this randomized clinical trial is to propose a physical exercise protocol based on concurrent training for middle-aged men with ADAM. METHOD: Randomized clinical trial with a 6-month intervention will randomly divided into two groups: experimental group (EG) and control group (CG). Four evaluations will be carried out, (1) pre-intervention; (2) in the first month of intervention; (3) in the third month of intervention; (4) post intervention, evaluating: physical, psychological, sexual, and hormonal aspects. The intervention protocol with concurrent training will have duration of 6 months; frequency of 3 times weekly, with 60 min per session. The two-way ANOVA test will be used for the inter-group and intra-group comparisons with repeated measurements, and also Sydak's comparison test. CONCLUSION: This protocol was developed with the intent of easing the symptoms of ADAM. In addition, it is believed that the concurrent training protocol could be capable to recover hormonal, physical, psychological, and sexual aspect of middle-aged men with ADAM. PMID- 29575952 TI - Association between dietary flavonoids intake and obesity in a cohort of adults living in the Mediterranean area. AB - Dietary polyphenols, including flavonoids, are abundantly present in a healthy and balanced diet. Evidence for their role in preventing non-communicable diseases is emerging. We examined the association between estimated habitual intake of dietary flavonoid and obesity in a cohort study. After adjusting for potential confounding factors, inverse association between total flavonoid intake and excess weight (BMI >=25) was found (OR = 0.66, 95% CI: 0.45, 0.99); among individual classes of flavonoids, only flavanones were inversely associated with excess body weight (OR = 0.68, 95% CI: 0.48, 0.97). However, when considering adjustment for dietary factors (adherence to the Mediterranean diet), the associations were no more significant. When considering obesity as the outcome (BMI >=30), individuals with high intake of total flavonoids and flavonols resulted less likely to be obese (OR = 0.38, 95% CI: 0.21, 0.66 and OR = 0.63, 95% CI: 0.39, 0.99, respectively), even after adjustment for confounding factors. The results of the present study add to the current literature further evidence of the association between higher flavonoid intake and decreased body weight. Further studies are needed to confirm retrieved association. PMID- 29575954 TI - Ototoxicity: The Radical Drum Beat and Rhythm of Cochlear Hair Cell Life and Death. AB - The function and structure of the auditory information processing system establishes a unique sensory environment for the "perfect storm." The battle between life and death pits the cascade of an apoptotic storm, programmed cell death cascades, against simple cell death (necrosis) pathways. Live or die, the free radical biology of oxygen and hydroxylation, and the destruction of transition metal migration through the mechanical gate sensory processes of the hair cell lead to direct access to the cytoplasm, cytoplasmic reticulum, and mitochondria of the inner workings of the hair cells. These lead to subsequent interactions with nuclear DNA resulting in permanent hearing loss. The yin and yang of pharmaceutical product development is to document what kills, why it kills, and how do we mitigate it. This review highlights the processes of cell death within the cochlea. PMID- 29575953 TI - Comparison of accepted and unaccepted living kidney donors: one-center experience. AB - BACKGROUND: Kidney transplantation from living donors (LD) has stagnated in many countries. This study aimed to check whether correction of LD selection practice could increase the number of kidney transplantations. METHODS: From January 2003 to December 2012, 241 potential adult LD were evaluated in our hospital. Outcome (mortality and end-stage renal disease-ESRD) of accepted LD (182) was compared with unaccepted (59) donors. RESULTS: Mortality of LD was comparable with that for the standardized Serbian population (SMR = 1.104; 95% CI (0.730-1.606). Among evaluated potential LD, almost every fourth had been unaccepted, but reasons were modifiable in 42.4% of them. In pre-donation period unaccepted donors were significantly older, measured glomerular filtration rate was lower, with higher 15-year and lifelong projected ESRD risks than accepted donors. Despite this, ten years outcome of both groups LD was similar: none of LD developed ESRD, 9.8% of accepted and 11.8% of unaccepted LD died (p = .803). CONCLUSIONS: During an average of 101 months of follow-up mortality of accepted LD did not differ significantly as compared to the age standardized Serbian population and none of them developed ESRD. In examination of potential LD, the use of accurate and precise methods for kidney function estimation and the evaluation of risk for ESRD and mortality as well as treatment of modifiable contraindications for kidney donation are necessary. PMID- 29575955 TI - Biofeedback in patients with ileoanal pouch dysfunction: a specialist centre experience. AB - OBJECTIVES: To report outcomes following biofeedback for functional problems associated with an ileoanal pouch. Incontinence and evacuatory disorders associated with the ileoanal pouch can be particularly problematic and difficult to treat using conventional therapies. Biofeedback therapy is a behavioural treatment that offers a non-surgical approach as an alternative or adjunct for patients. MATERIALS AND METHODS: This was a retrospective single centre study. We reviewed the notes of all patients attending for biofeedback at our institution between January 2012 and October 2017 and identified all those that did so for ileoanal pouch related problems. We recorded patient reported subjective improvements following biofeedback. The validated International Consultation on Incontinence Questionnaire was used to assess improvement in incontinent symptoms and the evacuatory disorder questionnaire was used to assess improvement in evacuatory disorders. RESULTS: Twenty-six patients with ileoanal pouch related problems underwent biofeedback. Based on patients' feedback at next clinical encounter following biofeedback, nine reported much improvement, 11 reported some improvement and six reported no improvement. In the group treated for incontinence, quality of life improved significantly from a median pre-treatment score of 80 to a post-treatment score of 41 (p = .01). Biofeedback reduced pain, bloating straining and laxative use in patients with evacuatory disorders. CONCLUSIONS: Biofeedback may be associated with significant improvement in quality of life as well as possible improvements in symptoms related to both incontinence and evacuatory disorders. It is probably an underused service. Further larger prospective studies are required to properly assess the efficacy of biofeedback in ileoanal pouch related dysfunction. PMID- 29575956 TI - Relation of locus 1p13 rs646776 polymorphism with the risk of preeclampsia. AB - OBJECTIVE: This study aimed to assess the relation of locus 1p13 rs646776 (T/C) polymorphism with preeclampsia in Egyptian women. METHODS: The study included 100 healthy pregnant female subjects and 100 preeclampsia patients. The genotypes of the polymorphisms were assessed. Endothelin-1 level was determined in plasma. RESULTS: The major T allele of the 1p13.3 genomic region rs646776 polymorphism had a higher frequency in preeclampsia patients. Carriers of C allele had significantly lower endothelin-1 levels, lower systolic and diastolic blood pressure, decreased proteinuria, and increased HDL-C in the patients. CONCLUSION: The rare C allele of rs646776 polymorphism in chromosomal locus 1p13.3 is associated with decreased risk of preeclampsia. PMID- 29575957 TI - Ventilator-induced lung injury during controlled ventilation in patients with acute respiratory distress syndrome: less is probably better. AB - INTRODUCTION: Mechanical ventilation is required to support respiratory function in the acute respiratory distress syndrome (ARDS), but it may promote lung damage, a phenomenon known as ventilator-induced lung injury (VILI). Areas covered: Several mechanisms of VILI have been described, such as: inspiratory and/or expiratory stress inducing overdistension (volutrauma); interfaces between collapsed or edema-filled alveoli with surrounding open alveoli, acting as stress raisers; alveoli that repetitively open and close during tidal breathing (atelectrauma); and peripheral airway dynamics. In this review, we discuss: the definition and classification of ARDS; ventilatory parameters that act as VILI determinants (tidal volume, respiratory rate, positive end-expiratory pressure, peak, plateau, driving and transpulmonary pressures, energy, mechanical power, and intensity); and the roles of prone positioning and muscle paralysis. We seek to provide an up-to-date overview of the evidence in the field from a clinical perspective. Expert commentary: To prevent VILI, mechanical ventilation strategies should minimize inspiratory/expiratory stress, dynamic/static strain, energy, mechanical power, and intensity, as well as mitigate the hemodynamic consequences of positive-pressure ventilation. In patients with moderate to severe ARDS, prone positioning can reduce lung damage and improve survival. Overall, volutrauma seems to be more harmful than atelectrauma. Extracorporeal support should be considered in selected cases. PMID- 29575958 TI - Overall benefits provided by orthopedic surgical intervention in patients with rheumatoid arthritis. AB - OBJECTIVES: To clarify systemic effects of orthopedic surgical intervention in patients with rheumatoid arthritis (RA). METHODS: A prospective observational cohort study was performed in RA patients who were scheduled to have primary elective orthopedic surgeries. Assessments were performed at baseline, 6 and 12 months after surgery using J-HAQ, General Health, EQ-5D, BDI-II, DAS28-CRP(4) and CRP for all registered patients, DASH and grip power for patients with upper extremity surgeries, TUG for patients with lower-extremity surgeries, and JSSF for patients with ankle and forefoot surgeries. RESULTS: There were 294 sites in 276 patients whose average age was 64 (19-89) years and average disease duration was 16 (1-60) years. Surgical site was shoulder in six patients, elbow in 26, wrist in 74, hand in 63, hip in 13, knee in 50, ankle in 12, and forefoot in 50. In total, physical function (J-HAQ, grip power, DASH, TUG, JSSF), quality of life (J-HAQ, General Health, EQ-5D) and depression (BDI-II) improved and disease activity (CRP, DAS28-CRP(4)) decreased significantly 6 and 12 months after surgery (p<.01), despite some differences in their outcomes by the preoperative disease activity and the surgical site. CONCLUSION: Overall benefits were provided by orthopedic surgical intervention generally in patients with RA. PMID- 29575959 TI - Pharmacological management of interstitial cystitis /bladder pain syndrome and the role cyclosporine and other immunomodulating drugs play. AB - INTRODUCTION: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a symptomatic disorder characterized by pelvic pain and urinary frequency. Immunological responses are considered as one of the possible etiologies of IC/BPS. In this review, we focused on emerging targets, especially on those modulating immunological mechanisms for the treatments of IC/BPS. Area covered: This review was based on the literature search of PubMed/MEDLINE, for which key words following bladder pain syndrome, interstitial cystitis, and/or cyclosporine A (CyA) were used. We discussed current treatments and the drugs targeting the immune responses including CyA and other drugs with different mechanisms including NGF antibodies and P2X3 antagonists. Expert commentary: IC/BPS is often difficult to treat by current treatments. Immunosuppression agents, especially CyA are considered as effective treatments for IC/BPS with Hunner's lesion because these drugs suppress the inflammatory responses in the bladder underlying urinary symptoms of the disease. Base on the previous literatures, we should use CyA for the refractory IC/BPS, especially that with Hunner's lesion due to its side effects. New drugs targeting other mechanisms such as urothelial or afferent nerve dysfunction or new delivery systems such as sustained drug releasing devices or gene therapy techniques may be promising for the future treatments of IC/BPS. PMID- 29575961 TI - Effect of magnetic field on haemodynamic perturbations in atherosclerotic coronary arteries. AB - Haemodynamic perturbations including elevated blood viscosity, low and oscillatory shear stress are understood to be important pathogenic mediators in atherosclerosis. These haemodynamic abnormalities are influenced by the presence of a magnetic field. This study conducted computational fluid dynamics (CFD) analysis in 4 coronary artery models, derived from authentic human coronaries, with mild and moderate and severe stenosis severity. The aim was to investigate the effect of a static magnetic field of varying intensities on blood viscosity, areas of low wall shear stress (ALWSS), maximum wall shear stress (MWSS) and length and volume of flow recirculation zones. The results showed that the magnetic field results in both beneficial and detrimental changes in haemodynamics. The beneficial effects are lowered viscosity, decreased size of ALWSS and flow recirculation zones whereas the detrimental effect is increased MWSS. With increasing stenosis severity the effect of magnetic field becomes more prominent. An externally applied magnetic field can improve haemodynamics perturbations in human coronary arteries, especially in the setting of moderate to-severe stenosis severity. PMID- 29575960 TI - Connective tissue growth factor expression after angiotensin II exposure is dependent on transforming growth factor-beta signaling via the canonical Smad dependent pathway in hypertensive induced myocardial fibrosis. AB - INTRODUCTION: Transforming growth factor-beta (TGF-beta) and connective tissue growth factor (CTGF) are often described as the initial pro-fibrotic mediators upregulated early in fibrosis models dependent on angiotensin II (Ang-II). In the present study, we explore the mechanistic link between TGF-beta and CTGF expression by using a novel TGF-beta trap. MATERIALS AND METHODS: NIH/3T3 fibroblasts were subjected to TGF-beta with or without TGF-beta trap or 1D11 antibody, CTGF or CTGF plus TGF-beta for six or 24 hours, and then used for quantitative real-time polymerase chain reaction (qRT-PCR) or immunocytochemistry. Male C57BL/6 mice were infused with Ang-II and randomly assigned TGF-beta trap for six or 24 hours. Hearts were harvested for histological analyses, qRT-PCR and western blotting. RESULTS: Exogenous TGF-beta induced fibroblasts resulted in significant upregulation of CTGF, TGF-beta and type I collagen transcript levels in vitro. Additionally, TGF-beta promoted the differentiation of fibroblasts into alpha-SMA+ myofibroblasts. CTGF expression was reduced by the addition of TGF-beta trap or neutralizing antibody, confirming that its expression is dependent on TGF-beta signaling. In contrast, exogenous CTGF did not appear to have an effect on fibroblast production of pro-fibrotic transcripts or fibroblast differentiation. Ang-II infusion in vivo led to a significant increase in TGF-beta and CTGF mRNA expression at six and 24 hours with corresponding changes in Smad2 phosphorylation (pSmad2), indicative of increased TGF-beta signaling. Ang-II animals that received the TGF-beta trap demonstrated reduced CTGF mRNA levels and pSmad2 at six hours, suggesting that early CTGF expression is dependent on TGF-beta signaling. CONCLUSIONS: We demonstrated that CTGF expression is dependent on TGF-beta signaling both in vitro and in vivo in a model of myocardial fibrosis. This also suggests that early myocardial CTGF mRNA expression (six hours) after Ang-II exposure is likely dependent on latent TGF-beta activation via the canonical Smad-dependent pathway in resident cardiac cells. PMID- 29575962 TI - Inhospital and delayed mortality after upper gastrointestinal bleeding: an analysis of risk factors in a prospective series. AB - BACKGROUND: Detailed analyses of mortality after upper gastrointestinal (GI) bleeding are lacking. Follow-up rarely extends beyond 30 days. AIMS: Our aim was to analyze in-hospital and delayed 6-months mortality, identifying risk factors. METHODS: This was a prospective study on patients with upper GI bleeding over 36 months. Clinical outcomes were in-hospital and delayed-6 month-mortality. RESULTS: Four hundred and forty-none patients were included. Overall inpatient mortality was 9.8% but mortality directly related to bleeding was 5.1%. Patients who died presented lower systolic blood pressures, platelet recounts, prothrombin times and lower levels of hemoglobin, calcium, albumin, urea, creatinine and total proteins. Cirrhosis and neoplasms determined a higher in-hospital mortality. Albumin levels were protective, whereas creatinine and an active bleeding were risk factors for in-hospital death in multivariate analysis. Up to 12.6% of patients discharged died in the first 6 months. Neoplasms, chronic kidney disease, coronary disease and esophageal varices were related to delayed mortality. Coronary disease and neoplasms were independent risk factors for mortality, but albumin levels were protective in multivariate analysis. CONCLUSION: Comorbidities were risk factors for delayed mortality, whereas albumin levels were a protective factor for in-hospital and delayed deaths. Six months mortality is proportionately as important as in-hospital mortality. Half of the delayed deaths might be preventable.

AB - INTRODUCTION: Atrial fibrillation (AF) is the commonest persistent cardiac arrhythmia with an estimated incidence rate of between 1.5-2% and an important cause of strokes. Few epidemiological studies and clinical trials on the management of AF have been conducted outside Europe and North America. These gaps in our understanding of AF likely lead to sub-optimal management of patients with AF in the rest of the world. Areas covered: We discuss the epidemiology, treatment and clinical outcomes for AF in the Middle East after systematic review of published work for AF from the Middle East. We also discuss important clinical trials on AF conducted in the West in the same period to help contextualize our findings. Expert commentary: The few available Middle East studies suggest important epidemiological differences between Middle Eastern and Western AF populations. In particular, the Middle Eastern AF population is younger and have more co-morbidities than patients in the West. We find that significant numbers of moderate to high risk patients with AF are either undertreated or untreated placing them at increased risk of complications such as stroke. More studies in the Middle Eastern population are required to aid the development of region specific clinical guidelines to improve patient care. PMID- 29575963 TI - Innovations in asthma therapy: is there a role for inhaled statins? AB - INTRODUCTION: Asthma manifests as chronic airflow obstruction with persistent inflammation and airway hyperresponsiveness. The immunomodulatory and anti inflammatory properties of the HMG-CoA reductase (HMGCR) inhibitors (a.k.a. statins), suggest a therapeutic role in chronic inflammatory lung diseases. However, despite positive laboratory investigations and promising epidemiological data, clinical trials using statins for the treatment of asthma have yielded conflicting results. Inadequate statin levels in the airway compartment could explain these findings. Areas covered: HMGCR is in the mevalonate (MA) pathway and MA signaling is fundamental to lung biology and asthma. This article will discuss clinical trials of oral statins in asthma, review lab investigations relevant to the systemic versus inhaled administration of statins, address the advantages and disadvantages of inhaled statins, and answer the question: is there a role for inhaled statins in the treatment of asthma? Expert commentary: If ongoing investigations show that oral administration of statins has no clear clinical benefits, then repurposing statins for delivery via inhalation is a logical next step. Inhalation of statins bypasses first-pass metabolism by the liver, and therefore, allows for delivery of significantly lower doses to the airways at greater potency. Statins could become the next major class of novel inhalers for the treatment of asthma. PMID- 29575966 TI - An Unusual Case of Extensive Osseous Metaplasia in Fibroma of Ovary.

AB - In light of official reports indicating a still prevalent tendency to masculinized obesity and overweight in Japan (Ministry of Health Labour and Welfare, 2015), this article explores the experiences of 28 Japanese men grappling with bodyweight control. Aged between 24 and 67, 3 of the men were postgraduate or undergraduate students, 7 self-employed, 17 company workers and 1 retired. Fourteen hold a university degree, 1 completed senior high school and 10 finished 3-year junior college. Twelve were married and 16 were single. Ten of the participants have been requested to lose weight because of being at risk of developing metabolic diseases, the rest have been called "chubby" ( debu) and all of them have unsuccessfully tried to lose weight. A set of two, in-depth semi structured interviews were conducted with each participant in Tokyo and Osaka in June and July 2015, 2016, and 2017. Grounded in symbolic interactionism, the interview analysis allows for a reading of the participants' embodied subjectivity in line with three axes: autodidact self, gendered self, and emotional self. The article highlights how the feminization of care has an effect on the participant's daily interactions. In conclusion, the article underscores the salience of "emotional attachment" to food (Lupton, 1998, p. 158), the "emotionalization" of food consumption and the emotionalization of the "fat body" in understanding their experiences dealing with corpulence in a country where slimness appears to be "ethnicized." PMID- 29575969 TI - The Effect of Testosterone Replacement Therapy on Penile Hemodynamics in Hypogonadal Men With Erectile Dysfunction, Having Veno-Occlusive Dysfunction. AB - Hypogonadism may cause veno-occlusive dysfunction (VOD) by structural and biochemical alterations in the cavernosal tissue. The aim of the study was to investigate the effect of testosterone replacement therapy (TRT) on penile hemodynamics in hypogonadal men with erectile dysfunction and VOD. The study included 32 hypogonadal men with erectile dysfunction, having VOD. All patients underwent penile color Doppler ultrasonography (PCDU) at the beginning and 6 months after the initial evaluation. Erectile function was evaluated with the 5 item version of the International Index of Erectile Function (IIEF-5); hypogonadism was evaluated by testosterone measurement and the Aging Male Symptoms (AMS) scale. All patients received transdermal testosterone 50 mg/day for 6 months. Clinical and radiological findings were compared before and 6 months after the TRT. The mean age was 58.81 +/- 4.56 (52-69) years. Mean total testosterone levels were 181.06 +/- 39.84 ng/dL and 509.00 +/- 105.57 ng/dL before and after the therapy, respectively ( p < .001). While all patients had physiological serum testosterone levels (>320 ng/dL) after the therapy, three cases (9.3%) had no clinical improvement of hypogonadism symptoms. Cavernosal artery peak systolic velocity (PSV) and resistive index (RI) significantly increased, and end diastolic velocity (EDV) significantly decreased after TRT. VOD no longer existed in 21 (65.6%) of the cases. This study demonstrated that TRT may restore penile hemodynamics in hypogonadal men with VOD. PMID- 29575970 TI - Medical Management of Endocarditis Caused by Stenotrophomonas maltophilia: A Case Report. AB - A 44-year-old female was found to be systemically ill at dialysis and admitted to the hospital. Days into the hospitalization, her blood cultures from dialysis were positive with Stenotrophomonas maltophilia bacteremia with a levofloxacin minimum inhibitory concentration (MIC) of 1. She was discharged on ciprofloxacin 500 mg orally (PO) daily on hospital day 2 to complete a 14-day course. Weeks later, she was again found to be bacteremic at dialysis and sent back to the hospital. She was started on empiric antibiotics upon admission until further identification. Blood cultures again revealed S. maltophilia with a levofloxacin MIC of 32. Antibiotics were tailored to trimethoprim/sulfamethoxazole (TMP-SMX) until susceptibilities for additional agents were available. Further workup revealed mitral valve endocarditis. She was subsequently discharged on both minocycline 100 mg PO every 12 hours and TMP-SMX 1 DS PO daily with a planned duration of 6 weeks. Due to ongoing readmissions for hyperkalemia, TMP-SMX was discontinued and her regimen was modified to ceftazidime 1 g intravenously (IV) after HD plus minocycline 100 mg PO every 12 hours. She was deemed clinically and microbiologically cleared based on follow-up assessments. To our knowledge, this is the first case of S. maltophilia endocarditis treated with oral minocycline in combination with another antibiotic. PMID- 29575971 TI - Prognosis and related factors of HPV infections in postmenopausal Uyghur women. AB - With the aim to explore the characteristics of persistent HPV infections in postmenopausal Uyghur women and analyse the possible related risk factors, from September 2012 to September 2013; postmenopausal Uyghur women with HPV positive and pathologically diagnosed as non-cervical intraepithelial neoplasia (CIN) lesions and non-cervical cancer were recruited. Their clinical course was closely followed up for 24-36 months, and the risk factors were analysed by a logistic regression model. One hundred and sixteen positive women were followed for 36 months. The total persistent HPV infection rate was 67.9%, and the type-specific persistent infection rate was 73.7% at 36 months. Nine (32.1%) women were naturally cleared of their HPV infection at 36 months. We found that an HPV16 infection and an HPV58 infection, and time since menopause over 2 years were closely related with a persistent HPV infection. More attention should be paid to the women above 2 years of menopause who were infected with HPV16 and HPV58 in their further cervical carcinoma screening. Impact statement What is already known on this subject? Previous study revealed that menopause was a risk factor for a persistent HPV infection in Uyghur women. What do the results of this study add? The present study presented the characteristics of HPV persistent infection and the risk factors in Uyghur postmenopausal women. More attention should be paid to the women above 2 of years of menopause who are infected with HPV16 and HPV58. What are the implications of these findings for clinical practice and/or further research? This study would offer a theoretical basis for a better screening design, especially the women above 2 years' menopause who have been infected with HPV16 and HPV58 in the Xinjiang region. PMID- 29575973 TI - Mental Health Among Help-Seeking Urban Women: The Relationships Between Adverse Childhood Experiences, Sexual Abuse, and Suicidality. AB - Adverse childhood experiences (ACEs) and adult mental health were explored in a sample of urban Aboriginal ( n = 83) and non-Aboriginal ( n = 89) women. Childhood sexual abuse (CSA) was associated with negative home environments, teenage pregnancy, lifetime suicide attempts, and treatment seeking. Aboriginal women with CSA witnessed higher levels of physical/sexual abuse of family members. The severity of current psychological distress was associated with a history of childhood neglect. The results indicate that CSA rarely occurs in isolation, and that multiple ACEs are strongly associated with suicide attempts and treatment seeking in adulthood. Future studies should focus on the role of CSA in suicidality, as well as familial, community, and cultural protective factors.

AB - Atrial arrhythmia (AA) occurrence in pulmonary arterial hypertension (PAH) may determine clinical deterioration and affect prognosis. In this study we assessed AA incidence in idiopathic (IPAH) and systemic sclerosis related PAH (SSc-PAH) and evaluated risk factors, management, and impact on mortality. We collected baseline data from consecutive IPAH or SSc-PAH patients prospectively enrolled in the Johns Hopkins Pulmonary Hypertension Registry between January 2000 and July 2016. During follow-up AA onset, treatment, and outcome were recorded. Among 317 patients (201 SSc-PAH, 116 IPAH), 42 developed AA (19 atrial fibrillation, 10 flutter-fibrillation, 9 atrial flutter, and 4 atrial ectopic tachycardia) with a 13.2% cumulative incidence. Most events were associated with hospitalization (90.5%). Electrical or pharmacological cardioversion was attempted in most cases. Patients with AA had higher right atrial pressure, pulmonary wedge pressure ( P < 0.005), NT-proBNP ( P < 0.05), and thyroid disease prevalence ( P < 0.005). Higher mortality was observed in patients with AA, though not statistically significant (LogRank P = 0.323). Similar long-term mortality between IPAH with AA and SSc-PAH without AA was observed (LogRank P = 0.098). SSc-PAH with AA had the worst prognosis. In PAH patients AA occurrence is a matter of significant concern. Therapeutic strategies aimed at restoring sinus rhythm may represent an important goal. PMID- 29575974 TI - Minority healthcare providers experience challenges, trust, and interdependency in a multicultural team. AB - BACKGROUND: The nursing community in the Nordic countries has become multicultural because of migration from European, Asian and African countries. In Norway, minority health care providers are recruited in to nursing homes which have become multicultural workplaces. They overcome challenges such as language and strangeness but as a group they are vulnerable and exposed to many challenges. PURPOSE: The aim is to explore minority healthcare providers, trained nurses and nurses' assistants, and their experiences of challenges when working in a multicultural team in a Norwegian context. RESEARCH METHOD: The study has a qualitative design, using narrative interviews, and a phenomenological hermeneutic analysis method to explore the experiences of challenges in dementia care. Ethical considerations: The study was approved by The Norwegian Regional Ethics Committee, and the Norwegian Social Science Data Services. Participation and research context: Five informants from different African, Asian and European countries participated in the study. The study was conducted in a Norwegian nursing home, in a dementia care unit. FINDINGS: The results show that minority health care providers experience and find meaning in being a member of a team, they overcome challenges, characterized by the interdependency in the team, appreciating new cultural experiences and striving to belong. They must overcome challenges such as language problems and the feeling of strangeness. DISCUSSION: The findings are discussed considering Logstrup's ethic of proximity, the ethical demand of trust, and interdependency. The ethical demand is an answer to a common, transparent, unspoken agreement to be met, seen, and understood. CONCLUSION: The study shows that cooperation in a multi-professional and multi ethnic team is important, and secures the quality of care to persons with dementia. Further research is necessary to examine the relation between a multi ethnic staff and the patients experiencing dementia. Further research is necessary to examine ethnicity, the relation between a multi-ethnic staff, the patients experiencing dementia and next of kin.

AB - Using a controlled parallel group longitudinal trial design, we investigated the effects of different training interventions on the prooxidant/antioxidant status of elite athletes: living and training at moderate altitude for 3 (Hi-Hi3) and 4 weeks (Hi-Hi), and for 4 weeks too, living high and training high and low (Hi HiLo) and living and training at sea level (Lo-Lo). From 61 swimmers, 54 completed the study. Nitrites, carbonyls, and lipid peroxidation (LPO) levels were assessed in plasma. Enzymatic antioxidants glutathione peroxidase (GPx) and glutathione reductase (GRd), and non-enzymatic antioxidants total glutathione (GST), reduced glutathione (GSH) and oxidized glutathione (GSSG) were analysed in the erythrocyte fraction. At the end of the intervention, nitrites levels were similar in all altitude groups but higher than in the Lo-Lo controls (P = .02). Hi-HiLo had greater GPx activity than Hi-Hi and Hi-Hi3 during most of the intervention (P <= .001). GRd activity was higher in Lo-Lo than in Hi-Hi at the end of the training camp (P <= .001). All groups showed increased levels of LPO, except Lo-Lo, and carbonyls at the end of the study (P <= .001). Training at altitude for 3 or 4 weeks drives oxidative stress leading to cellular damage mainly by worsening the antioxidant capacities. The GSSG/GSH ratio appears to be related to perceived exertion and fatigue. The stronger antioxidant defence showed by the Hi-HiLo group suggests an inverse relationship between redox alterations and performance. Further studies are required to investigate the role of oxidative stress in acclimatization, performance, and health. PMID- 29575976 TI - The effects of autobiographical memory and visual perspective on working memory. AB - The present research aims to explore whether recalling and writing about autobiographical memory from different perspectives (first-person perspective vs. third-person perspective) could affect cognitive function. The participants first performed a working memory task to evaluate their working memory capacity as a baseline and then were instructed to recall (Study 1) or write about (Study 2) personal events (failures vs. successes) from the first-person perspective or the third-person perspective. Finally, they performed the working memory task again. The results suggested that autobiographical memory and perspective influence working memory interactively. When recalling a success, the participants who recalled from the third-person perspective performed better than those who recalled from the first-person perspective on the working memory capacity task; when recalling a failure, the opposite was true. PMID- 29575978 TI - Decreasing dialysis catheter rates by creating a multidisciplinary dialysis access program. AB - INTRODUCTION:: Centers for Medicare and Medicaid Services have determined that chronic dialysis units should have <12% of their patients utilizing central venous catheters for hemodialysis treatments. On the Eastern Shore of Maryland, the central venous catheter rates in the dialysis units averaged >45%. A multidisciplinary program was established with goals of decreasing catheter rates in order to decrease central line-associated bloodstream infections, decrease mortality associated with central line-associated bloodstream infection, decrease hospital days, and provide savings to the healthcare system. METHODS:: We collected the catheter rates within three dialysis centers served over a 5-year period. Using published data surrounding the incidence and related costs of central line-associated bloodstream infection and mortality per catheter day, the number of central line-associated bloodstream infection events, the costs, and the related mortality could be determined prior to and after the initiation of the dialysis access program. RESULTS:: An organized dialysis access program resulted in a 82% decrease in the number of central venous catheter days which lead to a concurrent reduction in central line-associated bloodstream infection and deaths. As a result of creating an access program, central venous catheter rates decreased from an average rate of 45% to 8%. The cost savings related to the program was calculated to be over US$5 million. The decrease in the number of mortalities is estimated to be between 13 and 27 patients. CONCLUSION:: We conclude that a formalized access program decreases catheter rates, central line associated bloodstream infection, and the resultant hospitalizations, mortality, and costs. Areas with high hemodialysis catheter rates should develop access programs to better serve their patient population. PMID- 29575977 TI - Endothelial biomarkers in human sepsis: pathogenesis and prognosis for ARDS. AB - Experimental models of sepsis in small and large animals and a variety of in vitro preparations have established several basic mechanisms that drive endothelial injury. This review is focused on what can be learned from the results of clinical studies of plasma biomarkers of endothelial injury and inflammation in patients with sepsis. There is excellent evidence that elevated plasma levels of several biomarkers of endothelial injury, including von Willebrand factor antigen (VWF), angiopoietin-2 (Ang-2), and soluble fms-like tyrosine kinase 1 (sFLT-1), and biomarkers of inflammation, especially interleukin-8 (IL-8) and soluble tumor necrosis factor receptor (sTNFr), identify sepsis patients with a higher mortality. There are also some data that elevated levels of endothelial biomarkers can identify which patients with non-pulmonary sepsis will develop acute respiratory distress syndrome (ARDS). If ARDS patients are divided among those with indirect versus direct lung injury, then there is an association of elevated levels of endothelial biomarkers in indirect injury and markers of inflammation and alveolar epithelial injury in patients with direct lung injury. New research suggests that the combination of biologic and clinical markers may make it possible to segregate patients with ARDS into hypo- versus hyper-inflammatory phenotypes that may have implications for therapeutic responses to fluid therapy. Taken together, the studies reviewed here support a primary role of the microcirculation in the pathogenesis and prognosis of ARDS after sepsis. Biological differences identified by molecular patterns could explain heterogeneity of treatment effects that are not explained by clinical factors alone. PMID- 29575979 TI - Importance of the integrated test in the Down's syndrome screening algorithm. AB - OBJECTIVE: In the Czech Republic, over 97% of all pregnant women undergo some type of antenatal screening for Down's syndrome. In about 95% of cases with a confirmed fetal chromosomal abnormality, the pregnancy is terminated. The most commonly used test is the first trimester combined test. We investigated the impact of implementing an integrated sequential test to improve the detection of Down's syndrome pregnancies. METHODS: Data on the incidence of congenital defects, number of births, and affected pregnancies terminated are recorded in the National Registry of Congenital Anomalies. Anonymous data on cases of Down's syndrome diagnosed antenatally or postnatally between 2010 and 2015 in one of the large antenatal care centers were analyzed. RESULTS: There were 600 diagnoses of Down's syndrome (5.7 per 1000 births), 90% of which were made antenatally. Of antenatally detected cases, 80% were indicated for diagnostic procedure by multimarker screening results. In the multimarker screen positive group, 75% cases were first trimester positive and 25% second trimester positive (most of these had positive integrated test results). Among Down's syndrome cases indicated for antenatal diagnosis by multimarker screening results 6.25% (n = 26) were first trimester negative, and became positive after integration with the second trimester screening results. CONCLUSIONS: Results from five major Czech antenatal centers confirm that an integrated sequential test would detect 80-85% of Down's syndrome fetuses in the first trimester and at least an extra 5-10% of Down's syndrome pregnancies in the second trimester of pregnancy. These are important data that should be considered in implementing the national antenatal screening program. PMID- 29575980 TI - Atrazine affects craniofacial chondrogenesis and axial skeleton mineralization in zebrafish ( Danio rerio). AB - Atrazine is a commonly used herbicide that has previously been implicated as an endocrine-disrupting compound. Previous studies have shown that estrogenic endocrine-disrupting compounds affect the development of the heart, cartilage, and bone in zebrafish ( Danio rerio). To determine whether atrazine has effects similar to other endocrine disruptors, zebrafish embryos were treated with a range of atrazine concentrations. Atrazine treatment at a low concentration of 0.1 uM resulted in significant differences in craniofacial cartilage elements, while concentrations >=1 uM led to decreased survival and increased heart rates. Fish treated with >=1 uM atrazine also developed with delayed vertebrae mineralization. Higher concentrations of atrazine caused gross craniofacial defects and decreased hatching rates. Further studies into the molecular pathways disrupted in these developmental processes could shed light on a link between endocrine-disrupting compounds and developmental abnormalities.

AB - Our report aims to alert physicians performing endovascular aneurysm sealing with the Nellix endoprosthesis to the risk of rupture when endobag separation is noticed on computed tomography. Endobag separation when observed with acute presentation of abdominal pain is an indicator of imminent rupture and prompt interventional treatment should be undertaken. PMID- 29575982 TI - A Diabetes Mobile App With In-App Coaching From a Certified Diabetes Educator Reduces A1C for Individuals With Type 2 Diabetes. AB - Purpose There are currently many diabetes apps available, but there is limited evidence demonstrating clinical impact. The purpose of this study is to evaluate the impact of a diabetes mobile app with in-app coaching by a certified diabetes educator on glycemic control for individuals with type 2 diabetes. Methods A 12 week-long single-arm intent-to-treat trial evaluated the impact of a diabetes mobile app and coaching program (One Drop | Mobile With One Drop | Experts), which facilitated tracking of self-care and included an in-app diabetes education program, on A1C for individuals with type 2 diabetes and an A1C >=7.5% (58 mmol/mol). An online study platform (Achievement Studies, Evidation Health Inc, San Mateo, CA) was used to screen, consent, and enroll participants; collect study data; and track participants' progress throughout the study. Baseline and study end A1C measurements as well as questionnaire data from participants were collected. Results Participants (n = 146) were 52 +/- 9 years old, 71% female, 25% black or Hispanic, diagnosed with diabetes for 11 +/- 7 years, and with a mean baseline A1C of 9.87% +/- 2.0 (84 mmol/mol). In adjusted repeated measures models, mean A1C improved by -0.86% among study completers (n = 127), -0.96% among active users of the app and coaching program (n = 93), and -1.32% among active users with a baseline A1C >=9.0% (75 mmol/mol) (n = 53). Conclusions This program was associated with a clinically meaningful and significant reduction in A1C and can potentially increase access to effective diabetes self-management education and support for individuals with diabetes. PMID- 29575983 TI - Associative Attitude Learning: A Closer Look at Evidence and How It Relates to Attitude Models. AB - Associative attitude learning is typically viewed as a low-level process that automatically registers mere co-occurrences between stimuli, independent of their validity and relational meaning. This view invites to critically examine how attitude formation conforms to four operating conditions (i.e., unawareness, efficiency, goal independence, and uncontrollability) and two operating principles (i.e., unqualified registration of mere co-occurrences between stimuli and formation of direct stimulus-response links), which is the main purpose of the present contribution. The general discussion examines how contemporary attitude models endorse these conditions and principles. Overall, this contribution calls for (a) a nuanced understanding of the nature and scope of associative attitude learning, (b) a fine-grained understanding of how contemporary attitude models endorse conditions and principles reviewed here and find them relevant to their theorization of attitude formation, PMID- 29575984 TI - Population modification of Anopheles mosquitoes for malaria control: pathways to implementation. PMID- 29575985 TI - Successful treatment of severe combined post- and pre-capillary pulmonary hypertension in a patient with idiopathic restrictive cardiomyopathy. AB - Restrictive cardiomyopathy (RCM) is a rare form of cardiomyopathy that is characterized by restrictive ventricular filling. Elevated filling pressure leads to pulmonary hypertension (PH), which often progresses to combined post- and pre capillary PH (Cpc-PH) with increased diastolic pulmonary vascular pressure gradient (DPG) and pulmonary vascular resistance (PVR) caused by longstanding backward hemodynamic consequences of left heart disease (LHD) leading to morphological changes in the pulmonary vasculature. Patients with high PVR undergoing left ventricular assist device (LVAD) implantation are at increased risk of postoperative right-sided heart failure requiring concomitant implantation of a right ventricular assist device (RVAD). We report a case of RCM with severe Cpc-PH due to extremely elevated DPG and PVR. The patient presented recurrent syncope caused by severe PH. Right heart catheterization (RHC) revealed highly elevated DPG 30 mmHg and PVR 25.3 Wood units (WU) and subsequent significant reduction of right ventricular afterload during vasoreactivity testing with inhaled nitric oxide (NO) to DPG 5 mmHg and PVR 10.5 WU. During the administration of pulmonary vasodilators, pulmonary congestion worsened. Second RHC revealed elevated pulmonary arterial wedge pressure (PAWP) and modest decrease of pulmonary arterial pressure (PAP) 87 mmHg and PVR 9.6 WU. Therefore, an inotropic agent and systemic vasodilator were added for the treatment of left sided heart failure. Targeting elevated filling pressures with both PAH-specific and heart failure treatment, a further decrease of right ventricular afterload with DPG of 5 mmHg and PVR of 3.8 WU was achieved. In a next step, LVAD was successfully implanted, without need for RVAD, as a bridge to transplantation. This is the first reported case of Cpc-PH that revealed the potential reversibility of extremely elevated DPG and PVR, and suggests the importance of preoperative RHC-guided optimized medical PAH-specific and heart failure treatment before LVAD implantation. PMID- 29575986 TI - Nutrient salt removal by steel-making slag in sediment microbial fuel cells. AB - Applying sediment microbial fuel cells (SMFCs) into sediment can remediate the sediment; however, nutrient salts cannot be removed by SMFCs effectively. In this study, sediment mixed with steel-making slag is used a fuel in SMFCs for understanding the potential of steel-making slag in nutrient salt removal in SMFCs. To the best of our knowledge, no report related to the use of steel-making slag in SMFCs is found in the literature. The combination of SMFCs with steel making slag is expected to make the individual efficiency of SMFCs and steel making slag more reactive, and is another way to increase the benefit of using steel-making slag. Experimental results showed that steel-making slag was more effective for adsorbing nutrient salts in SMFCs. Interestingly, the combination of SMFCs with steel-making slag can increase the individual efficiency of SMFCs and steel-making slag. PMID- 29575987 TI - Network meta-analysis in health psychology and behavioural medicine: a primer. AB - Progress in the science and practice of health psychology depends on the systematic synthesis of quantitative psychological evidence. Meta-analyses of experimental studies have led to important advances in understanding health related behaviour change interventions. Fundamental questions regarding such interventions have been systematically investigated through synthesising relevant experimental evidence using standard pairwise meta-analytic procedures that provide reliable estimates of the magnitude, homogeneity and potential biases in effects observed. However, these syntheses only provide information about whether particular types of interventions work better than a control condition or specific alternative approaches. To increase the impact of health psychology on health-related policy-making, evidence regarding the comparative efficacy of all relevant intervention approaches - which may include biomedical approaches - is necessary. With the development of network meta-analysis (NMA), such evidence can be synthesised, even when direct head-to-head trials do not exist. However, care must be taken in its application to ensure reliable estimates of the effect sizes between interventions are revealed. This review paper describes the potential importance of NMA to health psychology, how the technique works and important considerations for its appropriate application within health psychology. PMID- 29575988 TI - Mycotoxins in infant/toddler foods and breakfast cereals in the US retail market. AB - The objective of this study was to conduct a mycotoxin survey of commercial infant/toddler foods (cereals and teething biscuits) and breakfast cereals in the United States. A total of 215 retail samples were collected from three geographical locations and analysed for aflatoxins, fumonisins, deoxynivalenol, HT-2 toxin, ochratoxin A, T-2 toxin, and zearalenone using a stable isotope dilution liquid-chromatography tandem mass spectrometry (LC-MS/MS) method. One or more mycotoxins were found in 69% (101/147) of the infant/toddler foods and 50% (34/68) of breakfast cereals. Mycotoxin co-occurrence was observed in 12% of infant/toddler foods and 32% of breakfast cereals. However, the concentrations of detected mycotoxins were lower than the current FDA action and guidance levels. Aflatoxins and HT-2 toxin were not detected in any of the samples, while deoxynivalenol was the most frequently detected mycotoxin. Rice-based cereals appeared to be less susceptible to mycotoxin contamination than other cereal types. PMID- 29575989 TI - Financial impact of oral chemotherapy wastage on society and the patient. AB - Background Targeted oral agents are now increasingly being utilized in cancer treatment, but are expensive. Changing the dose of these medications due to toxicity or discontinuation secondary to disease progression or death causes waste from unused medication. Limiting waste is an important goal, as waste has a substantial financial impact on patients and insurance companies. Methods Patients started on oral targeted agents' sunitinib, everolimus, axitinib, or vemurafenib between January 2012 and February 2015 who obtained their medications at Holden Comprehensive Cancer Center specialty pharmacy were included in the analysis. We acquired dispensing data retrospectively for each of the agents and reviewed patient charts. Wasted tablets/capsules were calculated from their last fill to the dates of stoppage or dose adjustment. The amount associated with the wastage was calculated using the average wholesale price. Repository drug usage data during the same time period was obtained. Results Eighty-eight patients had their prescriptions filled at Holden Comprehensive Cancer Center during the study time period. Waste occurred in 41% of all patients with primary reasons attributed to cancer progression in 25 patients, death in five patients, toxicity in five patients and increase in dosage of targeted therapy in two patients. A total of 1179 tablets or capsules were wasted from all causes, priced at a total of $248,595.69. Conclusion Oral chemotherapy medications are associated with wastage, which is a significant financial burden to society. Progression of disease emerged as the single most important factor accounting for wastage. Novel ideas are needed to prevent wastage, thereby reducing healthcare costs.

PMID- 29575990 TI - The effectiveness of cortico-cortical evoked potential in detecting seizure onset zones. AB - Objective The aim of the study was to evaluate the parameters for localizing the seizure onset zone in refractory epilepsy patients using cortico-cortical evoked potentials (CCEP). Methods Fifteen patients (nine females) with medically refractory partial epilepsy underwent stereo electro encephalography (SEEG) in Tsinghua University Yu-Quan Hospital from 2015 to 2016. Clinical semiology and, scalp electroencephalography (EEG) findings were analyzed during phase I preoperative evaluation. During phase II evaluation, localization of seizure onset zone (SOZ) was analyzed using SEEG by experienced epileptologists. Meanwhile, the cortico-cortical evoked potential (CCEP) paradigm was tested in all patients in phase II. The value of root-mean-square (RMS) of CCEPs amplitude from 7 ms to 300 ms after stimulation was analyzed to quantify the response. Results RMS of CCEPs amplitude in SOZ was higher than in seizure propagation zone (SPZ) (P < 0.05) and non-seizure onset zone (NSOZ) (P < 0.05). RMS of CCEPs amplitude in SOZ was higher than in NSOZ in epilepsy patients with secondary generalized tonic-clonic seizures (SGTCS) (N = 6, P < 0.05); The RMS of CCEPs amplitude in SOZ was strikingly higher than SPZ in the repetitive spiking (RS) onset pattern, and the difference was significant (N = 5, P < 0.01). Conclusions This data indicated that CCEP response is enhanced in SOZ despite different seizure types (with or without SGTCS). CCEP may be an effective method to locate SOZ. PMID- 29575992 TI - Below-the-Knee Retrograde Access for Peripheral Interventions: A Systematic Review. AB - PURPOSE: To investigate the hypothesis that interventions involving retrograde below-the-knee (BTK) vessel punctures have an acceptably low complication rate and high procedural success. METHODS: A systematic review was performed of the MEDLINE and Scopus databases for articles describing the results of BTK retrograde access for peripheral interventions. Outcome measures were access success, procedure success, and complications. A predefined subgroup analysis was performed of prospective studies to reduce the influence of possible reporting bias on outcomes. RESULTS: Nineteen articles, including 3 prospective studies, were selected, including a total of 1905 interventions in 1395 patients (mean age 69.5 years; 918 men). The BTK vessels were punctured in 1168 (61.3%) of these interventions. Access was successful in 94.0% of BTK attempts, 86.0% of all lesions were successfully crossed using a retrograde access, and 84.0% of interventions achieved technical success. Forty-eight (4.1%) distal access site complications were reported. Vessel perforations were seen in 13 (1.1%) interventions, vasospasm in 5 (0.4%), and acute distal occlusions in 5 (0.4%). Predefined subgroup analysis of prospective studies showed similar results (p=0.24). CONCLUSION: A retrograde approach to facilitate peripheral endovascular interventions is a safe and successful technique and should be considered when an antegrade approach is not possible or fails to cross the lesion. Because of missing data on long-term outcomes and methodological shortcomings, real world data of retrograde access in nonexpert centers remains necessary before this technique can be advised to all interventionists dealing with peripheral artery disease. PMID- 29575993 TI - Determination of Endograft Apposition, Position, and Expansion in the Aortic Neck Predicts Type Ia Endoleak and Migration After Endovascular Aneurysm Repair. AB - PURPOSE: To describe the added value of determining changes in position and apposition on computed tomography angiography (CTA) after endovascular aneurysm repair (EVAR) to detect early caudal displacement of the device and to prevent type Ia endoleak. METHODS: Four groups of elective EVAR patients were selected from a dataset purposely enriched with type Ia endoleak and migration (>10 mm) cases. The groups included cases of late type Ia endoleak (n=36), migration (n=9), a type II endoleak (n=16), and controls without post-EVAR complications (n=37). Apposition of the endograft fabric with the aortic neck, shortest distance between the fabric and the renal arteries, expansion of the main body (or dilatation of the aorta in the infrarenal sealing zone), and tilt of the endograft toward the aortic axis were determined on the first postoperative and the last available CTA scan without type Ia endoleak or migration. Differences in these endograft dimensions were compared between the first vs last scan and among the 4 groups. RESULTS: No significant differences in endograft configurations were observed among the groups on the first postoperative CTA scan. On the last CTA scan before a complication arose, the position of the fabric relative to the renal arteries, expansion of the main body, and apposition of the fabric with the aortic neck were significantly different between the type Ia endoleak (median follow-up 15 months) and migration groups (median follow-up 23 months) compared with the control group (median follow-up 19 months). Most endograft dimensions had changed significantly compared with the first postoperative CTA scan for all groups. Apposition had increased in the control group but had decreased significantly in the type Ia endoleak and migration groups. CONCLUSION: Progressive changes in dimensions of the endograft within the infrarenal neck could be detected on regular CTA scans before the complication became urgent in many patients. PMID- 29575996 TI - Soleus H-Reflex and Its Modulation With Vibration in Idiopathic Toe Walkers and Typically Developing Children. AB - Idiopathic toe walking is a relatively common developmental condition often leading to secondary problems such as pain and muscle contractures in the lower extremities. The cause of idiopathic toe walking is unknown, which hinders the development of treatment strategies. To test whether children with idiopathic toe walking have functional alterations in their spinal motor circuits, we studied the properties of the soleus H-reflex and its modulation with vibration in 26 idiopathic toe walkers and 16 typically developing children. At the group level, the H-reflex properties did not differ, but at the individual level, in 7 of 25 idiopathic toe walkers, some of the H-reflex parameters fell out of normal limits of typically developing children. However, the H-reflex was suppressed by vibration to the Achilles tendon similarly in both the idiopathic toe walkers and typically developing children. In conclusion, idiopathic toe walking in some children can be associated with functional alterations in their spinal motor circuits. PMID- 29575995 TI - Large Vessel Arteriopathy After Cranial Radiation Therapy in Pediatric Brain Tumor Survivors. AB - Among childhood cancer survivors, increased stroke risk after cranial radiation therapy may be caused by radiation-induced arteriopathy, but limited data exist to support this hypothesis. Herein, we assess the timing and presence of cerebral arteriopathy identified by magnetic resonance angiography (MRA) after cranial radiation therapy in childhood brain tumor survivors. In a cohort of 115 pediatric brain tumor survivors, we performed chart abstraction and prospective annual follow-up to assess the presence of large vessel cerebral arteriopathy by MRA. We identified 10 patients with cerebral arteriopathy. The cumulative incidence of arteriopathy 5 years post-cranial radiation therapy was 5.4% (CI 0.6%-10%) and 10 years was 16% (CI 4.6%-26%). One patient had an arterial ischemic stroke 2.4 years post-cranial radiation therapy in the distribution of a radiation-induced stenotic artery. We conclude that large vessel arteriopathies can occur within a few years of cranial radiation therapy and can become apparent on MRA in under a year. PMID- 29575997 TI - 1,25(OH)2D3 Protects Trophoblasts Against Insulin Resistance and Inflammation Via Suppressing mTOR Signaling. AB - Gestational diabetes mellitus (GDM) is the primary cause of maternal and fetal morbidity and mortality. Insulin resistance (IR) is pivotal to GDM pathogenesis, and mammalian target of rapamycin (mTOR) is a critical regulator of GDM. An increasing amount of evidence indicates that vitamin D deficiency is a risk factor for GDM. However, there are few reports on the effect of IR on GDM placentas. The present study aims to verify that 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) can ameliorate trophoblast IR by suppressing mTOR signaling. An IR BeWo cell model was established in the presence of high insulin and glucose medium. The IR level and mTOR activation with or without 1,25(OH)2D3 treatment were evaluated. The IR cells exhibited excessive mTOR signaling activation, upregulated inflammatory factor levels, and extensive lipid infiltration. However, 1,25(OH)2D3 reversed mTOR activation and reduced the IR level and lipid infiltration. In addition, 1,25(OH)2D3 treatment in GDM placental explants blocked the aberrant, increased levels of leptin, TNF-alpha, and IL-6. Therefore, 1,25(OH)2D3 treatment protects trophoblasts against high IR mainly through suppressing mTOR signaling, and this mechanism may serve as a potential therapy for patients with GDM. PMID- 29575998 TI - Human Endometrial Reconstitution From Somatic Stem Cells: The Importance of Niche Like Cells. AB - Endometrial regeneration has long been proposed to be mediated by stem cells, but the isolation of endometrial stem cells has been hampered by a lack of validated markers. Specific markers would enable isolation of these stem cells, thereby promoting advancements in regenerative medicine for the treatment of endometrial diseases and dysfunctions. We sought to investigate the regenerative ability of human endometrial positive for sushi domain containing 2/intercellular adhesion molecule 1 (SUSD2+/ICAM1+) cells and Side Population cell lines in a xenograft mice model. The injection of total endometrial cell suspensions and Side Population cell lines under kidney capsules induced neoformation of human endometrium verified by the presence of typical endometrial markers (vimentin, cytokeratin 18, and progesterone receptor) by immunofluorescence. Total endometrial cell types promoted a better reconstitution in comparison to injecting ICAM1+ and SUSD2+ cells alone. The endometrial fraction is probably acting as a niche, resulting in increased reconstruction efficiency of pure fractions. Human engrafted cells were localized near blood vessels and induced the proliferation of surrounding cells. Our results suggest that human endometrial Side Population, a heterogeneous population possibly harboring endometrial stem cells, has the optimum capacity to regenerate endometrial-like tissue. In contrast, cells positive for single stem cell markers SUSD2 and ICAM1 have minimally functional regenerative capacities in the absence of niche-like cells. PMID- 29575999 TI - Epigenetic Drugs in the Treatment of Endometriosis. PMID- 29576000 TI - Uterine Autotransplantation in the Nonhuman Primate With Preservation of the Uterine and Ovarian Vascular Pedicles. AB - PURPOSE: To evaluate the technical feasibility of performing a uterine autotransplantation in the nonhuman primate while preserving the uterine and ovarian vascular pedicles. METHODS: Eight (n = 8) female baboons at a primate research facility underwent a uterine autotransplant procedure with preservation of the vascular pedicles. The uterine arteries were separated from their amorphous tissue and skeletonized toward the internal iliac arteries bilaterally. A segment of the internal iliac artery was removed bilaterally along with both uterine arteries. Both ovarian veins were preserved to assist with the reperfusion of the uterine organ. Due to larger vascular pedicles in one of the primates, the uterine arteries were separated and reattached directly via end-to end anastomosis. In another baboon, the deep uterine vein was used as a vascular pedicle rather than the ovarian vein on the left side due to adequate size and visualization. RESULTS: Immediate tissue reperfusion occurred intraoperatively in 5 of the animals, with slower perfusion in 3 of the animals. Average warm ischemia time was 43.8 minutes while the average cold ischemia time was 174 minutes (2 hours, 54 minutes). Average total surgical time was 5.9 hours. All animals were sheltered into separate cages and monitored for behavior changes and food and drink consumption. Three of the primates expired immediately postoperatively, 2 from severe dehydration and 1 from gastric aspiration. CONCLUSIONS: This pilot study describes a modified surgical approach for uterine transplants in the nonhuman primate. This surgical technique may be applicable to living and deceased donor uterine transplantation.

AB - OBJECTIVES: To evaluate the impact of metformin on in vitro fertilization (IVF) outcomes in overweight and obese women with polycystic ovary syndrome (PCOS). METHODS: This was a randomized double-blind placebo-controlled study ( ClinicalTrials.gov : NCT 02910817) carried out in a University IVF Center. The study included 102 overweight and obese women (body mass index [BMI] >24 kg/m2) with PCOS who underwent their first fresh autologous IVF-embryo transfer cycle and agreed to participate in the study. The study participants were randomized into 2 groups: metformin group received metformin (1000 mg per day) at the start of controlled ovarian stimulation (COH) until the day of the pregnancy check, and placebo group received placebo tablets in the same duration. The primary outcome measure was the total number of retrieved oocytes. RESULTS: Both groups were homogenous in baseline demographic characteristics. Metformin group versus the placebo group demonstrated decrease in the mean number of the retrieved oocytes (9.06 +/- 4.23 vs 16.86 +/- 8.3, P < .01) and similar live birth rate (LBR; 25.5% vs 17.6%, P = .34). The number of fertilized oocytes was lower in the metformin group (5.65 +/- 2.66 vs 9 +/- 4.55, P < .01). However, the fertilization rate was similar in both groups (62.3% vs 53.4%, P = .10). There was no difference in the implantation rate (15.7% vs 11.8%, P = .32), multiple pregnancy rate (13.4% vs 3.9%, P = .08), or miscarriage rate (23.5% vs 35.7%, P = .46). No cases of ovarian hyperstimulation syndrome (OHSS) were observed in both groups. CONCLUSION: Short-term administration of metformin to overweight or obese women with PCOS undergoing IVF decreased number of the retrieved oocytes but did not improve the LBR. Synopsis Metformin use could decrease the number of retrieved oocytes in overweight and obese women with polycystic ovary syndrome undergoing IVF.

AB - Systemic monitoring of immune system may not precisely outline the local immune status in the uterus. This survey is a continuation of our previous studies on potential usefulness of menstrual blood (MB) immunophenotyping as a tool for investigation of immunological disturbances in pregnancy-related disorders. Peripheral blood (PB) and MB from healthy fertile (n = 15), unexplained recurrent spontaneous abortion (URSA; n = 15), and unexplained infertile women (n = 8) were collected simultaneously in the second day of their menstrual cycle and frequency of natural killer T (NKT)-like cell subpopulations were assessed by flow cytometry. Menstrual blood of all experimental groups contained higher percentage of TCRalphabeta+, CD45RO+, and CD16- NKT-like cells compared to corresponding PB. Frequency of MB NKT-like cells in unexplained infertile participants was lower than fertile and URSA groups. Compared to normal participants, patients with URSA had lower frequency of PB TCRalphabeta+ and higher CD16+, while in infertile woman frequencies of PB CD45RO+, CD45RO-, CD16-, IL17+, and MB CD45RO+ NKT-like cells were lower. Although, PB and MB seemingly have the same histological nature, our results showed that MB contained different composition of NKT-like subsets with different cytokine profiles and could be viewed as one potential biological sample for evaluation of patients with infertility and URSA.

AB - INTRODUCTION: Chronic kidney disease (CKD) is a predictor of poor outcomes for patients undergoing endovascular aortic aneurysm repair (EVAR). Anatomic severity grade (ASG) represents a quantitative mechanism for assessing anatomical suitability for endovascular aortic repair. Anatomic severity grade has been correlated with repair outcomes and resource utilization. The purpose of this study was to identify a novel renal perfusion metric as a way to assist ASG with predicting EVAR outcomes. METHODS: Retrospective review of a prospectively maintained database identified elective infrarenal aortic aneurysm repair cases. Anatomic grading was undertaken by independent reviewers. Using volumetric software, kidney volume, and a novel measure of kidney functional volume, the volumetric nephrogram (VN) was recorded. Systematic evaluation of the relationship of kidney volume and VN to CKD and ASG was undertaken using linear regression and receiver-operator statistical tools. RESULTS: A total of 386 cases with patient and anatomic data were identified and graded. Mean age was 72.9 +/- 0.4 years. Renal volume <281 mL correlated with CKD (area under the curve [AUC] = .708; P <= .0001). Volumetric nephrogram <22.5 HU.L correlated with CKD (AUC = 0.764; P <= .0001). High (>=15) ASG scores correlated with both renal volume (AUC = .628; P <= .0001) and VN (AUC = .628; P <= .0001). Regression analysis demonstrated a strong, inverse relationship between ASG and VN ( R2 = .95). CONCLUSION: These data demonstrate that VN is a strong predictor of CKD in a large database of patients undergoing elective aneurysm repair. We demonstrate an inverse relationship between renal function and ASG that has not been previously described in the literature. Additionally, we have shown that VN complements ASG as a model of overall cardiovascular health and atherosclerotic burden. Outcomes in patients with poor renal function may be related to anatomical issues in addition to well-described systemic ramifications.

PMID- 29576007 TI - The Evaluation of Aortic Diameter Changes During Long-Term Follow-Up After Endovascular Treatment of Acute Blunt Traumatic Thoracic Aortic Injuries. AB - PURPOSE: To evaluate the variations in aortic diameters and long-term results in patients who underwent thoracic endovascular aortic repair (TEVAR) for acute blunt traumatic thoracic aortic injuries (BTTAIs). MATERIALS AND METHODS: We retrospectively evaluated 23 patients with a mean age of 39 years (range: 17-74 years) who underwent TEVAR for BTTAI between October 2000 and November 2014. All of the patients underwent computed tomography angiography (CTA) before hospital discharge as a baseline imaging for the subsequent follow-up examinations. The technical success, overall survival, and complications were evaluated. Furthermore, the aortic diameters outside of the stent-graft (1 cm proximal and 1 cm distal to the stent-graft) and the aortic diameters within the stent-graft (2 cm distal to the proximal end and 2 cm proximal to the distal end) were assessed. The diameters at baseline on CTA were compared with those of the latest available follow-up examination. RESULTS: Technical success was 100% with a mean follow-up of 65.4 months (range: 12-171 months). No death was registered, and 2 (8.7%) of 23 endograft-related complications (1 stent-graft distal infolding and 1 endoleak 2 and 4 months after the procedure, respectively) were observed. An increase in aortic diameter either proximal or distal to the stent-graft (mean value 0.7 and 0.5 mm, respectively) or within the stent-graft (mean value of 0.5 mm for both proximal and distal diameters) was registered (mean follow-up at 65.4 months, range: 12-171 months). CONCLUSION: Aortic dilatation following TEVAR for BTTAI is minimal during long-term follow-up. Endovascular treatment represents a durable and safe option in acute BTTAIs. PMID- 29576010 TI - Geographic origin as a determinant of left ventricular mass and diastolic function - the Cardiovascular Risk in Young Finns Study. AB - AIMS: Eastern Finns have higher risk of coronary heart disease (CHD) and carotid intima-media thickness than western Finns although current differences in CHD risk factors are minimal. Left ventricular (LV) mass and diastolic function predict future cardiovascular events but their east-west differences are unknown. We examined the association of eastern/western baseline origin with LV mass and diastolic function. METHODS: The study population included 2045 subjects of the Cardiovascular Risk in Young Finns Study with data from the baseline survey (1980) and the latest follow-up (2011) when echocardiography was performed at the age of 34-49 years. RESULTS: Subjects with eastern baseline origin had in 2011 higher LV mass (139+/-1.0 vs. 135+/-1.0 g, p=0.006) and E/e'-ratio indicating weaker LV diastolic function (4.86+/-0.03 vs. 4.74+/-0.03, p=0.02) than western subjects. Results were independent of age, sex, area of examination and CHD risk factors such as blood pressure and BMI (LV mass indexed with height: p<0.0001; E/e'-ratio: p=0.01). LV end-diastolic volume was higher among subjects with eastern baseline origin (135+/-0.9 vs. 131+/-0.9 ml, p=0.0011) but left atrial end-systolic volume, also indicating LV diastolic function, was not different between eastern and western subjects (43.4+/-0.5 vs. 44.0+/-0.5 ml, p=0.45). Most of the subjects were well within the normal limits of these echocardiographic measurements. CONCLUSIONS: In our healthy middle-aged population, geographic origin in eastern Finland associated with higher LV mass compared to western Finland. Higher E/e'-ratio suggests that subjects with eastern baseline origin might have higher prevalence of diastolic dysfunction in the future than western subjects.

AB - AIM: This study investigated time trend and regional disparities in hospitalisations due to osteoarthritis (OA) among people aged >=20 years in Sweden from 1998 through 2015. METHODS: National and regional data on hospital admissions with a primary diagnosis of OA were collected from the National Patient Register. The absolute and relative regional disparities were assessed using the absolute weighted mean difference from overall mean and the index of disparity. We applied joinpoint regression for temporal trend analysis of hospitalisations and the Mann-Kendall trend test for disparity measures. Changes in number of OA hospitalisations between 1998-2000 and 2013-2015 were analysed using two counterfactual scenarios. RESULTS: During 1998-2015, OA hospitalisations constituted 2.0% of all hospitalisations, with higher proportions among women (58.7%) and those aged 70-74 years (18.0%). The age standardised rate of OA hospitalisation and its proportions from all and musculoskeletal disorders hospitalisations rose, on average, by >2.0% per year during the study period. OA hospitalisation rates rose statistically significantly in all age groups except for the youngest and oldest age groups. The proportion of hip OA from all OA hospitalisations declined, while the opposite was observed for knee OA. The relative regional disparities declined in men, and the absolute regional disparities rose among women over time. The population growth and ageing could explain only about one third of the observed increases in the absolute number of OA hospitalisations between 1998-2000 and 2013-2015. CONCLUSIONS: OA hospitalisations have increased substantially, suggesting the need to improve OA prevention and primary-care management in Sweden. PMID- 29576012 TI - Output-oriented analysis of the wet mechanical processing of polyolefin-rich waste for feedstock recycling. AB - In recent years, an increasing number of studies have revealed that plastics and their components (e.g. plasticisers) pose an environmental risk. However, it is hard to imagine how our industrialised society could do without these materials, since the fields of application are manifold. One possible approach to tackle this mounting problem is the implementation of a comprehensive and well functioning collection and recycling system. An international comparison shows that only a small proportion of the total plastics in circulation is collected and recycled. The investigations conducted under the present research project, 'Plastic Reborn', focused on both identification and analysis of the discharge paths of polyolefin-rich waste streams, under the Austrian waste management system. Another objective was determining the utilisation potential of the output fractions of these polyolefin-rich waste streams, generated from a wet mechanical processing pilot plant. Experiments have shown that the polyolefins are successfully separated from the waste streams and that a total polyolefin potential of 429,000 t y-1 remains unexploited in the Austrian waste management system. Thus, these separated plastic fractions can make a significant contribution to the implementation of the European Circular Economy Directive. The residual fractions meet the legal and company-specific requirements for their use as solid recovered fuels in co-combustion plants. PMID- 29576013 TI - Omega-3 fatty acid supplement reduces activation of NADPH oxidase in intracranial atherosclerosis stenosis. AB - Objectives Intracranial atherosclerotic stenosis (ICAS) is one of the most common causes of stroke worldwide. We adapted a rat model of atherosclerosis to study brain intracranial atherosclerosis, and further investigated how omega-3 fatty acids (O3FA) attenuated the development of ICAS by reducing the generation of reactive oxygen species (ROS) and the activation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) activity. Methods Adult male Sprague Dawley rats were divided into control normal-cholesterol or high-cholesterol diet groups with or without O3FA for up to 6 weeks. NG-nitro-L-arginine methyl ester (L-NAME, 3 mg/mL), a nitric oxide synthase inhibitor, was added to the drinking water of the high-cholesterol groups during the first 2 weeks. The rats received supplementation with O3FA (5 mg/kg/day) by gavage. At 3 and 6 weeks, we measured blood lipid levels, including low-density lipoprotein (LDL), cholesterol (CHO), triglycerides (TG), and high-density lipoprotein (HDL) as atherosclerotic blood markers. The lumen of middle cerebral artery (MCA) and the thickness of the vessel wall were assessed histologically. ROS production was measured. NOX activity and mRNA and protein expression of NOX subunits (p47phox, gp91phox, p22phox, and p67phox) were measured. Results A high-cholesterol diet exhibited a significant increase in the classic blood markers (LDL, CHO, and TG) for atherosclerosis, as well as a decrease in HDL. These markers were found to be progressively more severe with time. Additionally, increased lumen stenosis and intimal thickening were observed in the MCA for this group. Rats given O3FA demonstrated attenuation of blood lipid levels with an absence of morphological changes.O3FA significantly reduced ROS production and NOX activity in the brain. Moreover, O3FA decreased the mRNA and protein expression of the NOX subunits p47phox, gp91phox, and p67phox. Conclusions Long-term O3FA dietary supplementation prevents the development of intracranial atherosclerosis. This O3FA effect appears to be mediated by its attenuation of NOX subunit expression and NOX activity, therefore reducing ROS production. O3FA dietary supplement shows promising results in the prevention of ICAS. PMID- 29576014 TI - Eigen decomposition expedites longitudinal genome-wide association studies for milk production traits in Chinese Holstein. AB - BACKGROUND: Pseudo-phenotypes, such as 305-day yields, estimated breeding values or deregressed proofs, are usually used as response variables for genome-wide association studies (GWAS) of milk production traits in dairy cattle. Computational inefficiency challenges the direct use of test-day records for longitudinal GWAS with large datasets. RESULTS: We propose a rapid longitudinal GWAS method that is based on a random regression model. Our method uses Eigen decomposition of the phenotypic covariance matrix to rotate the data, thereby transforming the complex mixed linear model into weighted least squares analysis. We performed a simulation study that showed that our method can control type I errors well and has higher power than a longitudinal GWAS method that does not include time-varied additive genetic effects. We also applied our method to the analysis of milk production traits in the first three parities of 6711 Chinese Holstein cows. The analysis for each trait was completed within 1 day with known variances. In total, we located 84 significant single nucleotide polymorphisms (SNPs) of which 65 were within previously reported quantitative trait loci (QTL) regions. CONCLUSIONS: Our rapid method can control type I errors in the analysis of longitudinal data and can be applied to other longitudinal traits. We detected QTL that were for the most part similar to those reported in a previous study in Chinese Holstein. Moreover, six additional SNPs for fat percentage and 13 SNPs for protein percentage were identified by our method. These additional 19 SNPs could be new candidate quantitative trait nucleotides for milk production traits in Chinese Holstein. PMID- 29576015 TI - Management of a giant retroperitoneal leiomyoma: a case report. AB - BACKGROUND: Leiomyomas are benign tumors observed mainly in adult women. The retroperitoneum is a rare location for leiomyomas; almost 100 cases have been reported. Because retroperitoneal leiomyomas are paucisymptomatic and the tumor size at diagnosis is relatively large, surgical management is challenging. Regular follow-up is required because recurrence and malignant sarcomatous transformation have been described in a few cases. CASE PRESENTATION: We report a case of a 52-year-old North African woman with a 22-cm retroperitoneal leiomyoma. A preoperative embolization was performed 2 days before surgery. The clinical, therapeutic, and evolutive aspects of this rare entity are discussed. CONCLUSIONS: Despite its benignity, retroperitoneal leiomyoma is a challenging diagnostic, therapeutic, and evolutive condition. Surgeons must consider mainly the tumor's vascularization. Regular follow-up is mandatory because malignant transformation cannot be excluded.

PMID- 29576017 TI - Diagnostic double strike in the emergency room - two cases of complete pancreatic ruptures due to bicycle handlebar injuries on two consecutive days. AB - BACKGROUND: Pancreatic injuries are rare in cases of blunt abdominal trauma and therefore easily misdiagnosed at time of hospital admission. They are associated with a significantly elevated morbidity and lethality. Bicycle handlebar injuries are the most common cause of pancreatic trauma in children and adolescents. CASE PRESENTATION: We report two cases of a 23-year-old Caucasian woman and a 15-year old Caucasian boy who presented to our clinic with a similar history of a bicycle accident on 2 consecutive days. Both suffered from a fall from a bicycle with bicycle handlebar injury 4 and 6 days prior to admission in our clinic. Emergency distal pancreatectomies were performed in both cases. CONCLUSIONS: Pancreatic injuries must be highly suspected in bicycle handlebar injuries, even if amylase/lipase levels or ultrasound findings seem unremarkable. The best initial strategies are early computed tomography and a quick referral to a level 1 trauma center. Distal pancreatectomy is the treatment of choice in cases of complete rupture of the pancreatic body.

PMID- 29576018 TI - The ctenophore Mnemiopsis leidyi regulates egg production via conspecific communication. AB - BACKGROUND: Communication between individuals of the same species is an important aspect of mating and reproduction in most animals. In simultaneously hermaphroditic species with the ability to self-fertilize, communication with conspecifics can be essential to avoid inbreeding depression. One such behavioral adaptation observed in some simultaneous hermaphrodites is gamete trading. This behavior involves individual hermaphrodites in pairs alternating between reproducing as the male and female, and, as such, necessarily requires communication and coordination between mates. Little is known about communication in ctenophores and conspecific communication has not been described in this group; however, our previous work suggested that the ctenophore Mnemiopsis leidyi might engage in gamete trading. We tested for this possibility by constructing divided arenas (both sealed and permeable) that allowed us to measure individual egg output for paired M. leidyi. RESULTS: We found that, when not allowed to interact, size-matched individuals produced similar numbers of eggs on each side of the arena. However, if allowed to interact and exchange water, size-matched pairs produce significantly different numbers of eggs on each side of the arena, suggesting that these pairs use chemical communication to modulate reproduction in the presence of conspecifics as would be expected in gamete trading. CONCLUSION: This finding presents exciting new possibilities for future investigations into the nature of signaling in M. leidyi. Furthermore, this first evidence of conspecific communication in Ctenophora, a group that branched off from the rest of animals more than 600 million years ago, has significant implications for the signaling ability of the last common ancestor of all animals. PMID- 29576020 TI - New mastitis phenotypes suitable for genomic selection in meat sheep and their genetic relationships with udder conformation and lamb live weights. AB - Mastitis can prove expensive in sheep reared for meat production due to costs associated with treatment methods, poor lamb growth and premature culling of ewes. The most commonly used method to detect mastitis, in dairy systems, is somatic cell counts. However, in many meat-producing sheep flocks ewes are not routinely handled, thus regular milk sampling is not always possible. It is, therefore, worthwhile to investigate alternative phenotypes, such as those associated with udder conformation and methods of evaluating somatic cell counts in the milk, such as the California Mastitis Test. The main objectives of this study were therefore: (a) to estimate genetic parameters of traits relating to mastitis and udder conformation in a meat sheep breed; (b) estimate the level of association between somatic cell counts and the California Mastitis Test and (c) assess the relationships between mastitis and both udder conformation and lamb live weights. Data were collected from Texel ewes based on 29 flocks, throughout the UK, during 2015 and 2016. The ewes were scored twice each year, at mid- and late-lactation. Eight different conformation traits, relating to udder and teat characteristics, and milk samples were recorded. The data set comprised of data available for 2957 ewes. The pedigree file used contained sire and dam information for 31 775 individuals. The animal models used fitted relevant fixed and random effects. Heritability estimates for traits relating to mastitis (somatic cell score and the California Mastitis Test), ranged from 0.08 to 0.11 and 0.07 to 0.11, respectively. High genetic correlations were observed between somatic cell score and the California Mastitis Test (0.76 to 0.98), indicating the California Mastitis Test to be worthwhile for assessing infection levels, particularly at mid-lactation. The strongest correlations observed between the mastitis traits and the udder conformation traits were associated with udder depth (0.61 to 0.75) also at mid-lactation. Negative phenotypic correlations were estimated between mastitis and the weight of lamb reared by the ewe (-0.15 to 0.23), suggesting that lamb weights fell as infection levels rose. Genetic correlations were not significantly different from zero. Reducing mastitis will lead to improvements in flock productivity and the health and welfare of the animals. It will also improve the efficiency of production and the resilience to disease challenge. The economic benefits, therefore, of these results combined could be substantial not only in this breed but also in the overall meat sheep industry. PMID- 29576022 TI - Genetic risk for neuroticism predicts emotional health depending on childhood adversity. AB - BACKGROUND: Existing evidence for gene * environment interaction (G * E) in neuroticism largely relies on candidate gene studies, although neuroticism is highly polygenic. This study aimed to investigate the long-term associations between polygenic risk scores for neuroticism (PRSN), objective childhood adversity and their interplay on emotional health aspects such as neuroticism itself, depressive symptoms, anxiety symptoms, loneliness and life satisfaction. METHODS: The sample consisted of reared-apart (TRA) and reared-together (TRT) middle- and old age twins (N = 699; median age at separation = 2). PRSN were created under nine p value cut-off thresholds (p T-s) and the p T with the highest degree of neuroticism variance explained was chosen for subsequent analyses. Linear regressions were used to assess the associations between PRSN, childhood adversity (being reared apart) and emotional health. G * E was further investigated using a discordant twin design. RESULTS: PRSN explained up to 1.7% (p T < 0.01) of phenotypic neuroticism in the total sample. Analyses across two separation groups revealed substantial heterogeneity in the variance explained by PRSN; 4.3% was explained in TRT, but almost no effect was observed in TRA. Similarly, PRSN explained 4% and 1.7% of the variance in depressive symptoms and loneliness, respectively, only in TRT. A significant G * E interaction was identified for depressive symptoms. CONCLUSIONS: By taking advantage of a unique sample of adopted twins, we demonstrated the presence of G * E in neuroticism and emotional health using PRSN and childhood adversity. Our results may indicate that genome-wide association studies are detecting genetic main effects associated with neuroticism, but not those susceptible to early environmental influences. PMID- 29576021 TI - Caregiver perceptions of children's linear growth in Bangladesh: a qualitative analysis. AB - OBJECTIVE: To understand caregivers' perceptions of children's linear growth and to identify the cultural meanings and perceptions of risk associated with poor height attainment. DESIGN: Three investigators from Bangladesh conducted twelve focus group discussions. SETTING: The study was conducted in rural and slum settings in Bangladesh. SUBJECTS: Participants included mothers and alternative caregivers (n 81) who were recruited by household screening. No eligible, recruited subjects refused participation. RESULTS: Caregivers reported limited experience with growth monitoring services from the health system. Caregivers mainly use visual cues and developmental milestones to understand if children are growing properly, and recognize that children normally experience both weight gain and linear growth with age. Mothers expressed concern over children's malnutrition and short stature, but did not discuss children's failure to attain a 'growth potential' or distinguish inherited short stature from stunting. Caregivers interpret the consequences of poor height attainment as primarily social and economic and cite few health risks. CONCLUSIONS: Linear growth interpretation is determined more by community norms than by guidance from nutrition programming or the health system. Interventions to prevent or reduce linear growth failure may be perceived to have limited value where appropriate linear growth in children is determined by comparison to peers and siblings. Such perceptions may be significant barriers to programmes addressing stunting prevention in settings where many children are stunted. Efforts to raise awareness about the risks of linear growth faltering may need to consider delivering messages to caregivers that emphasize the social and economic consequences of stunting. PMID- 29576023 TI - A successful Charter challenge to medicare? Policy options for Canadian provincial governments. AB - In September 2016, a case went to trial in British Columbia that seeks to test the constitutionality of provincial laws that (1) ban private health insurance for medically necessary hospital and physician services; (2) ban extra-billing (physicians cannot charge patients more than the public tariff); and (3) require physicians to work solely for the public system or 'opt-out' and practice privately. All provinces have similar laws that have been passed to meet the requirements of federal legislation, the Canada Health Act (and thus qualify for federal funds). Consequently, a finding of unconstitutionality of one or more of these laws could have a very significant impact on the future of Canada's single payer system ('medicare'). However, should the court find that a particular law is not in compliance with the Canadian Charter of Rights and Freedoms, the baton is then passed back to the government which may respond with other laws or policies that they believe to be constitutionally compliant. The ultimate impact of any successful Charter challenge to laws protecting medicare from privatization will thus significantly depend on how Canadian governments respond. Provincial governments could allow privatization to undercut equity and access, or they could respond creatively with new legal and policy solutions to both improve equity and access and tackle some of the problems that have long bedeviled Canadian medicare. This paper provides an understanding - grounded in comparative health systems evidence - of law and policy options available to Canadian lawmakers for limiting two-tier care in the wake of any successful challenge to existing laws. The paper presents the results of a large inter disciplinary, comparative study, started in 2015, that systematically reviewed the legal and broader regulatory schemes used to regulate the public/private divide in 15 Organization for Economic Co-Operation and Development countries with a particular eye to what the effect of such regulations would be upon wait times. PMID- 29576024 TI - Source of bias in sugar-sweetened beverage research: a systematic review. AB - OBJECTIVE: Financial conflicts of interest involving the food industry have been reported to bias nutrition studies. However, some have hypothesized that independently funded studies may be biased if the authors have strong a priori beliefs about the healthfulness of a food product ('white hat bias'). The extent to which each source of bias may affect the scientific literature has not been examined. We aimed to explore this question with research involving sugar sweetened beverages (SSB) as a test case, focusing on a period during which scientific consensus about the adverse health effects of SSB emerged from uncertainty. DESIGN: PubMed search of worldwide literature was used to identify articles related to SSB and health risks published between 2001 and 2013. Financial relationships and article conclusions were classified by independent groups of co-investigators. Associations were explored by Fischer's exact tests and regression analyses, controlling for covariates. RESULTS: A total of 133 articles published in English met inclusion criteria. The proportion of industry related scientific studies decreased significantly with time, from approximately 30 % at the beginning of the study period to <5 % towards the end (P=0.003). A 'strong' or 'qualified' scientific conclusion was reached in 82 % of independent v. 7 % of industry-related SSB studies (P<0.001). Industry-related studies were overwhelmingly more likely to reach 'weak/null' conclusions compared with independent studies regarding the adverse effects of SSB consumption on health (OR=57.30, 95 % CI 7.12, 461.56). CONCLUSION: Industry-related research during a critical period appears biased to underestimate the adverse health effects of SSB, potentially delaying corrective public health action. PMID- 29576025 TI - When health technology assessment is confidential and experts have no power: the case of Hungary. AB - Health technology assessment (HTA) is not simply a mechanistic technical exercise as it takes place within a specific institutional context. Yet, we know little about how this context influences the operation of HTA and its ability to influence policy and practice. We seek to demonstrate the importance of considering institutional context, using a case study of Hungary, a country that has pioneered HTA in Central and Eastern Europe. We conducted 26 in-depth, semi structured interviews with public- and private-sector stakeholders. We found that while the HTA Department, the Hungarian HTA organisation, fulfilled its formal role envisaged in the legislation, its potential for supporting evidence-based decision-making was not fully realised given the low levels of transparency and stakeholder engagement. Further, the Department's practical influence throughout the reimbursement process was perceived as being constrained by the payer and policy-makers, as well as its own limited organisational capacity. There was also scepticism as to whether the current operational form of the HTA process delivered 'good value for money'. Nevertheless, it still had a positive impact on the development of a broader institutional HTA infrastructure in Hungary. Our findings highlight the importance of considering institutional context in analysing the HTA function within health systems. PMID- 29576026 TI - Developmental trends of hot and cool executive function in school-aged children with and without autism spectrum disorder: Links with theory of mind. AB - The development of executive function (EF) in autism spectrum disorder (ASD) has been investigated using only "cool"-cognitive EF tasks while there is limited knowledge regarding the development of "hot"-affective EF. Although cool EF development and its links to theory of mind (ToM) have been widely examined, understanding of the influence of hot EF to ToM mechanisms is minimal. The present study introduced a longitudinal design to examine the developmental changes in cool and hot EF of children with ASD (n = 45) and matched (to age and IQ) controls (n = 37) as well as the impact of EF on ToM development over a school year. For children with ASD, although selective cool (working memory and inhibition) and hot (affective decision making) EF domains presented age-related improvements, they never reached the performance level of the control group. Early cool working memory predicted later ToM in both groups but early hot delay discounting predicted later ToM only in the ASD group. No evidence was found for the reverse pattern (early ToM predicting later EF). These findings suggest that improvements in some EF aspects are evident in school age in ASD and highlight the crucial role that both cool and hot EF play in ToM development. PMID- 29576027 TI - Automatic food detection in egocentric images using artificial intelligence technology. AB - OBJECTIVE: To develop an artificial intelligence (AI)-based algorithm which can automatically detect food items from images acquired by an egocentric wearable camera for dietary assessment. DESIGN: To study human diet and lifestyle, large sets of egocentric images were acquired using a wearable device, called eButton, from free-living individuals. Three thousand nine hundred images containing real world activities, which formed eButton data set 1, were manually selected from thirty subjects. eButton data set 2 contained 29 515 images acquired from a research participant in a week-long unrestricted recording. They included both food- and non-food-related real-life activities, such as dining at both home and restaurants, cooking, shopping, gardening, housekeeping chores, taking classes, gym exercise, etc. All images in these data sets were classified as food/non-food images based on their tags generated by a convolutional neural network. RESULTS: A cross data-set test was conducted on eButton data set 1. The overall accuracy of food detection was 91.5 and 86.4 %, respectively, when one-half of data set 1 was used for training and the other half for testing. For eButton data set 2, 74.0 % sensitivity and 87.0 % specificity were obtained if both 'food' and 'drink' were considered as food images. Alternatively, if only 'food' items were considered, the sensitivity and specificity reached 85.0 and 85.8 %, respectively. CONCLUSIONS: The AI technology can automatically detect foods from low-quality, wearable camera-acquired real-world egocentric images with reasonable accuracy, reducing both the burden of data processing and privacy concerns. PMID- 29576028 TI - Anomalous Brain Development Is Evident in Preschoolers With Attention Deficit/Hyperactivity Disorder. AB - OBJECTIVES: Attention-deficit/hyperactivity disorder (ADHD) is a common neurological disorder with symptom onset early in childhood. Growing evidence suggests anomalous brain development across multiple brain regions is evident in school-aged children; however, few studies have examined whether such differences are notable in the preschool years when symptom onset typically occurs. METHODS: High resolution anatomical (MPRAGE) images and cognitive and behavioral measures were analyzed in a total of 90 medication-naive preschoolers, ages 4-5 years (52 with ADHD, 38 controls; 64.4% boys). RESULTS: Results revealed reductions in bilateral frontal, parietal, and temporal lobe gray matter volumes in children with ADHD relative to typically developing children, with largest effect sizes noted for right frontal and left temporal lobe volumes. Examining frontal lobe sub-regions, the largest between group effect sizes were evident for left orbitofrontal cortex, left primary motor cortex (M1), and left supplementary motor complex (SMC). ADHD-related reductions in specific sub-regions (left prefrontal, left premotor, left frontal eye field, left M1, and right SMC) were significantly correlated with symptom severity, such that higher ratings of hyperactive/impulsive symptoms were associated with reduced cortical volumes. CONCLUSIONS: These findings represent the first comprehensive examination of cortical volume in preschool children with ADHD, providing evidence that anomalous brain structure in ADHD is evident very early in development. Furthermore, findings set the stage for developing our understanding of the way in which developmental trajectories of anomalous brain development are associated with the unfolding of symptoms in childhood ADHD.

AB - BACKGROUND: Encounters play an important role in the relationship between healthcare personnel and the close relatives of people with a long-term illness.AimThe aim of this study was to elucidate the meanings of encounters for close relatives of people with a long-term illness within a primary healthcare setting. METHODS: Interviews using a narrative approach were conducted with seven women and three men, and the phenomenological hermeneutic method was used to interpret the interview texts. RESULTS: The structural analysis revealed three major themes: being confirmed as a family, being informed of the care, and being respected as a valuable person. Close relatives stated that they wanted to be confirmed as a family and have a familiar and trusting relationship with healthcare personnel. They valued being informed concerning the care of the ill person so that they could give support at home. It was also important to be compassionately viewed as an important person in a welcoming atmosphere based on respect and dignity. PMID- 29576029 TI - A review of guidance on fish consumption in pregnancy: is it fit for purpose? AB - OBJECTIVE: Public health messages to reduce Hg exposure for pregnant women have focused exclusively on advice on fish consumption to limit Hg exposure, with little account being taken of the positive contribution of fish to nutritional quality. The aim of the present review was to compare and contrast the content and presentation of national guidelines on fish consumption in pregnancy, and comment on their evidence base and impact on consumption. DESIGN: We searched for national and international guidelines on fish consumption in pregnancy using Internet search strategies. The detailed content and style of presentation of the guidelines were compared. The evidence base for the guidelines, and evidence for the impact of the guidelines on fish consumption levels, were assessed. RESULTS: We identified nineteen national guidelines and three international guidelines. There was great variation in the content, complexity and presentation style. The guidelines were based largely on the Hg content of fish with far less consideration being given to the positive beneficial effects of nutrients provided by fish. The complexity of the guidelines may lead to pregnant women reducing their fish intake, or not eating fish at all. CONCLUSIONS: Guidelines on fish consumption in pregnancy should take the beneficial effects of fish into account. Guidelines need to be clear and memorable, and appropriately disseminated, to achieve impact. Guidelines could include visual rather than narrative content. Use of technology, for example apps, could enable women to record their fish consumption in real time and log compliance with guidance over a week or other time period.

AB - OBJECTIVE: Excess meat consumption, particularly of red and processed meats, is associated with nutritional and environmental health harms. While only a small portion of the population is vegetarian, surveys suggest many Americans may be reducing their meat consumption. To inform education campaigns, more information is needed about attitudes, perceptions, behaviours and foods eaten in meatless meals. DESIGN: A web-based survey administered in April 2015 assessed meat reduction behaviours, attitudes, what respondents ate in meatless meals and sociodemographic characteristics. SETTING: Nationally representative, web-based survey in the USA. SUBJECTS: US adults (n 1112) selected from GfK Knowledgeworks' 50 000-member online panel. Survey weights were used to assure representativeness. RESULTS: Two-thirds reported reducing meat consumption in at least one category over three years, with reductions of red and processed meat most frequent. The most common reasons for reduction were cost and health; environment and animal welfare lagged. Non-meat reducers commonly agreed with statements suggesting that meat was healthy and 'belonged' in the diet. Vegetables were most often consumed 'always' in meatless meals, but cheese/dairy was also common. Reported meat reduction was most common among those aged 45-59 years and among those with lower incomes. CONCLUSIONS: The public and environmental health benefits of reducing meat consumption create a need for campaigns to raise awareness and contribute to motivation for change. These findings provide rich information to guide intervention development, both for the USA and other high-income countries that consume meat in high quantities. PMID- 29576033 TI - Child neglect and its relation to emotional and behavioral problems: A cross sectional study of primary school-aged children in Tanzania. AB - Child maltreatment is known to engender negative emotional and behavioral consequences. Although neglect is the most frequent form of maltreatment, it has thus far only received little attention, especially when looking at low-resource countries. The current study investigated possible associations between neglect and internalizing and externalizing problems. As neglect and abuse often co occur, the latter was controlled for. In total, 409 Tanzanian primary school students (52% boys, M = 10.5 years, range = 6-15) participated in the cross sectional study. Structured clinical interviews were conducted assessing maltreatment, internalizing problems, and externalizing problems. Overall, 31% (n = 128) of the children reported at least one type of physical neglect and 31% (n = 127) of emotional neglect. Using structural equation modeling, we found a significant association between neglect and internalizing (beta = 0.59, p < .01) and externalizing problems (beta = 0.35, p < .05). However, these associations could only be detected in younger children (ages 6-9), whereas in older children (ages 10-15), mental health problems were significantly related to violence and abuse. Our findings suggest that the current age may influence the association between maltreatment type and the development of internalizing and/or externalizing problems. PMID- 29576034 TI - Science and self-assessment: phrenological charts 1840-1940. AB - This paper looks at phrenological charts as mediators of (pseudo-)scientific knowledge to individual clients who used them as a means of self-assessment. Phrenologists propagated the idea that the human mind could be categorized into different mental faculties, with each particular faculty represented in a different area of the brain and by bumps on the head. In the US and the UK popular phrenologists examined individual clients for a fee. Drawing on a collection of phrenological charts completed for individual clients, this paper shows how charts aspired to convey new ideals of selfhood by using the authority of science in tailor-made certificates, and by teaching clients some of the basic practices of that science. Hitherto historians studying phrenology have focused mainly on the attraction of the content of phrenological knowledge for the wider public, but in this paper I show how the charts enabled clients to participate actively in creating knowledge of their own bodies and selves. PMID- 29576035 TI - Cortisol, cortisone, and BDNF in amniotic fluid in the second trimester of pregnancy: Effect of early life and current maternal stress and socioeconomic status. AB - The prenatal environment shapes the offspring's phenotype; moreover, transgenerational stress and stress during pregnancy may play a role. Brain derived neurotrophic factor (BDNF) and glucocorticoids influence neurodevelopment during pregnancy, and there is evidence that BDNF in amniotic fluid is mainly of fetal origin, while the source of glucocorticoids is maternal. We tested the hypothesis that maternal early life stress, psychiatric diagnoses, anxiety, perceived stress, and socioeconomic status influence BDNF and glucocorticoid concentrations in amniotic fluid in the second trimester. We studied 79 pregnant women who underwent amniocentesis in the early second trimester and analyzed BDNF, cortisol, and cortisone concentrations in amniotic fluid. The endocrine data were related to maternal early life adversities (Childhood Trauma Questionaire), perceived stress (Perceived Stress Scale), anxiety, socioeconomic status (family income), and the presence of psychiatric diseases. We found BDNF in amniotic fluid to be positively related to maternal early adversity (Childhood Trauma Questionaire). Low family income (socioeconomic status) was related to high amniotic fluid glucocorticoid concentrations. Neither glucocorticoid concentrations nor hydroxy steroid dehydrogenase (HSD2) activity could be related to BDNF concentrations in amniotic fluid. Early maternal adverse events may be reflected in the fetal BDNF regulation, and it should be tested whether this relates to differences in neurodevelopment.

PMID- 29576037 TI - The Mediating Role of Coping between Competitive Anxiety and Sport Commitment in Adolescent Athletes. AB - Framed in cognitive-motivational-relational theory of emotions (Lazarus, 1999), this study aimed to test how coping mediated the relationship between competitive anxiety and sport commitment in a sample of adolescent athletes. Five-hundred adolescents (M = 16.42; SD = 1.54) participated in our study. Participants completed competitive anxiety, coping, and sport commitment measures. We defined the measurement model using confirmatory factor analysis and exploratory structural equation modeling; and compared two different models of mediation (i.e., total and partial mediation) using structural equation modeling. Results favored partial mediation model where cognitive anxiety factors predicted sport commitment. Results from this model suggest direct and mediated structural relations between concepts. Somatic anxiety had a weak influence on sport commitment (total effects = 0.090 [-.131, .311]). Worry showed a positive influence on sport commitment (total effects = .375 [.262, .486]) through direct and mediated effects. Concentration disruption showed a negative impact on sport commitment (total effects = -.544 [-.724, -.363]) trough mediated effects only, showing a negative path on task-oriented coping and a positive path on disengagement-oriented coping. As a whole, our findings identify task coping efforts undertaken by adolescent athletes as a key element in the relationship between competitive anxiety and sport commitment. These findings provide preliminary evidence for the design of coping interventions in adolescents. PMID- 29576038 TI - Predictors of Suicide Behavior Relapse in Pediatric Population. AB - Identifying patients at increased risk of suicide remains a challenge today. It has been reported that 10% of patients committing a suicide attempt end up dying and that both the risk and the severity of clinical symptomatology increase with the number of attempts. Within the framework of selective and indicated prevention, it is essential to identify the group of patients with an increased risk of recurrence. The objective of this study is to identify factors predicting suicide attempt relapse to improve the decision making process in the therapeutic approach to suicidal behavior. The methodology employed was a longitudinal design aimed at identifying factors, in a binary logistic regression model (stepwise), predicting the repetition of suicidal behavior among a sample of 417 participants aged between 8 and 17 years old, at the six months follow-up. A statistically significant model chi2(3, N = 417) = 18.610; p < .001; Nagelkerke R 2 = .096 including the following factors was obtained: current diagnosis of personality disorder/maladaptive personality OR = .806, p = .028, 95% CI [1.091, 4.595], personal history of self-injury OR = .728, p = .043, 95% CI [1.023, 4.192], and family history of psychopathological diagnosis OR = .925, p = .021, 95% CI [1.151, 5.530]. Considering these results, having a diagnosis of personality disorder or maladaptive personality traits, presence or history of self-harm and family history of psychopathology draws a predictive profile of autolytic attempt recurrence during the six months after the initial intervention at the emergency room. PMID- 29576039 TI - Performance, health and physiological responses of newly weaned feedlot cattle supplemented with feed-grade antibiotics or alternative feed ingredients. AB - With increased regulations regarding the use of feed-grade antimicrobials in livestock systems, alternative strategies to enhance growth and immunity of feedlot cattle are warranted. Hence, this experiment compared performance, health and physiological responses of cattle supplemented with feed-grade antibiotics or alternative feed ingredients during the initial 60 days in the feedlot. Angus*Hereford calves (63 steers+42 heifers) originating from two cow-calf ranches were weaned on day -3, obtained from an auction yard on day -2 and road transported (800 km; 12 h) to the feedlot. Upon arrival on day -1, shrunk BW was recorded. On day 0, calves were ranked by sex, source and shrunk BW, and allocated to one of 21 pens. Pens were assigned to receive (7 pens/treatment) a free-choice total mixed ration containing: (1) lasalocid (360 mg/calf daily of Bovatec; Zoetis, Florham Park, NJ, USA)+chlortetracycline (350 mg/calf of Aureomycin at cycles of 5-day inclusion and 2-day removal from diet; Zoetis) from days 0 to 32, and monensin only (360 mg/calf daily of Rumensin; Elanco Animal Health, Greenfield, IN, USA) from days 33 to 60 (PC), (2) sodium saccharin-based sweetener (Sucram at 0.04 g/kg of diet dry matter; Pancosma SA; Geneva, Switzerland)+plant extracts containing eugenol, cinnamaldehyde and capsicum (800 mg/calf daily of XTRACT Ruminants 7065; Pancosma SA) from days 0 to 32 and XTRACT only (800 mg/calf daily) from days 33 to 60 (EG) or (3) no supplemental ingredients (CON; days 0 to 60). Calves were assessed for bovine respiratory disease (BRD) signs and dry matter intake was recorded from each pen daily. Calves were vaccinated against BRD pathogens on days 0 and 22. Shrunk BW was recorded on day 61, and blood samples collected on days 0, 6, 11, 22, 33, 43 and 60. Calf ADG was greater (P=0.04) in PC v. EG and tended (P=0.09) to be greater in PC v. CON. Feed efficiency also tended (P=0.09) to be greater in PC v. CON, although main treatment effect for this response was not significant (P=0.23). Mean serum titers against bovine respiratory syncytial virus were greater in EG v. PC (P=0.04) and CON (tendency; P=0.08). Collectively, the inclusion of alternative feed ingredients prevented the decrease in feed efficiency when chlortetracycline and ionophores were not added to the initial feedlot diet, and improved antibody response to vaccination against the bovine respiratory syncytial virus in newly weaned cattle. PMID- 29576040 TI - Genome-wide identification of runs of homozygosity islands and associated genes in local dairy cattle breeds. AB - Runs of homozygosity (ROH) are widely used as predictors of whole-genome inbreeding levels in cattle. They identify regions that have an unfavorable effect on a phenotype when homozygous, but also identify the genes associated with traits of economic interest present in these regions. Here, the distribution of ROH islands and enriched genes within these regions in four dairy cattle breeds were investigated. Cinisara (71), Modicana (72), Reggiana (168) and Italian Holstein (96) individuals were genotyped using the 50K v2 Illumina BeadChip. The genomic regions most commonly associated with ROHs were identified by selecting the top 1% of the single nucleotide polymorphisms (SNPs) most commonly observed in the ROH of each breed. In total, 11 genomic regions were identified in Cinisara and Italian Holstein, and eight in Modicana and Reggiana, indicating an increased ROH frequency level. Generally, ROH islands differed between breeds. The most homozygous region (>45% of individuals with ROH) was found in Modicana on chromosome 6 within a quantitative trail locus affecting milk fat and protein concentrations. We identified between 126 and 347 genes within ROH islands, which are involved in multiple signaling and signal transduction pathways in a wide variety of biological processes. The gene ontology enrichment provided information on possible molecular functions, biological processes and cellular components under selection related to milk production, reproduction, immune response and resistance/susceptibility to infection and diseases. Thus, scanning the genome for ROH could be an alternative strategy to detect genomic regions and genes related to important economic traits. PMID- 29576041 TI - The prevalence of depression in general hospital inpatients: a systematic review and meta-analysis of interview-based studies. AB - BACKGROUND: Comorbid depression in the medically ill is clinically important. Admission to a general hospital offers an opportunity to identify and initiate treatment for depression. However, we first need to know how common depression is in general hospital inpatients. We aimed to address this question by systematically reviewing the relevant literature. METHODS: We reviewed published prevalence studies in any language which had used diagnostic interviews of general hospital inpatients and met basic methodological quality criteria. We focussed on interview-based studies in order to estimate the proportion of patients with a diagnosis of depressive illness. RESULTS: Of 158 relevant articles, 65 (41%) describing 60 separate studies met our inclusion criteria. The 31 studies that focussed on general medical and surgical inpatients reported prevalence estimates ranging from 5% to 34%. There was substantial, highly statistically significant, heterogeneity between studies which was not materially explained by the covariates we were able to consider. The average of the reported prevalences was 12% (95% CI 10-15), with a 95% prediction interval of 4-32%. The remaining 29 studies, of a variety of specific clinical populations, are described. CONCLUSIONS: The available evidence suggests a likely prevalence high enough to make it worthwhile screening hospital inpatients for depression and initiating treatment where appropriate. Further, higher quality, research is needed to clarify the prevalence of depression in specific settings and to further explore the reasons for the observed heterogeneity in estimates. PMID- 29576042 TI - A Generalizable, Data-Driven Approach to Predict Daily Risk of Clostridium difficile Infection at Two Large Academic Health Centers. AB - OBJECTIVE An estimated 293,300 healthcare-associated cases of Clostridium difficile infection (CDI) occur annually in the United States. To date, research has focused on developing risk prediction models for CDI that work well across institutions. However, this one-size-fits-all approach ignores important hospital specific factors. We focus on a generalizable method for building facility specific models. We demonstrate the applicability of the approach using electronic health records (EHR) from the University of Michigan Hospitals (UM) and the Massachusetts General Hospital (MGH). METHODS We utilized EHR data from 191,014 adult admissions to UM and 65,718 adult admissions to MGH. We extracted patient demographics, admission details, patient history, and daily hospitalization details, resulting in 4,836 features from patients at UM and 1,837 from patients at MGH. We used L2 regularized logistic regression to learn the models, and we measured the discriminative performance of the models on held out data from each hospital. RESULTS Using the UM and MGH test data, the models achieved area under the receiver operating characteristic curve (AUROC) values of 0.82 (95% confidence interval [CI], 0.80-0.84) and 0.75 ( 95% CI, 0.73-0.78), respectively. Some predictive factors were shared between the 2 models, but many of the top predictive factors differed between facilities. CONCLUSION A data driven approach to building models for estimating daily patient risk for CDI was used to build institution-specific models at 2 large hospitals with different patient populations and EHR systems. In contrast to traditional approaches that focus on developing models that apply across hospitals, our generalizable approach yields risk-stratification models tailored to an institution. These hospital-specific models allow for earlier and more accurate identification of high-risk patients and better targeting of infection prevention strategies.

AB - Mobile applications (apps) are promising tools to support chronic disease screening and linkage to health services. They have the potential to increase healthcare access for vulnerable populations. The HealthNavigator app was developed to provide chronic disease risk assessments, linkage to local general practitioners (GPs) and lifestyle programs, and a personalised health report for discussion with a GP. Assessments were either self-administered or facilitated by community health workers through a Primary Health Network (PHN) initiative targeting ethnically diverse communities. In total, 1492 assessments (80.4% self administered, 19.6% facilitated) were conducted over a 12-month period in Queensland, Australia. Of these, 26% of people screened came from postcodes representing the lowest quartile of socioeconomic disadvantage. When compared against self-administered assessments, subjects screened by the facilitated program were more likely to be born outside Australia (80.5 v. 33.2%, P<0.001), and to fall within a high risk category based on cardiovascular risk scores (19.8 v. 13.7%, P<0.01) and type 2 diabetes mellitus risk scores (58.0 v. 40.1%, P<0.001). Mobile apps embedded into PHN programs may be a useful adjunct for the implementation of community screening programs. Further research is needed to determine their effect on health service access and health outcomes. PMID- 29576045 TI - Current perspectives of CASA applications in diverse mammalian spermatozoa. AB - Since the advent of computer-aided sperm analysis (CASA) some four decades ago, advances in computer technology and software algorithms have helped establish it as a research and diagnostic instrument for the analysis of spermatozoa. Despite mammalian spermatozoa being the most diverse cell type known, CASA is a great tool that has the capacity to provide rapid, reliable and objective quantitative assessment of sperm quality. This paper provides contemporary research findings illustrating the scientific and commercial applications of CASA and its ability to evaluate diverse mammalian spermatozoa (human, primates, rodents, domestic mammals, wildlife species) at both structural and functional levels. The potential of CASA to quantitatively measure essential aspects related to sperm subpopulations, hyperactivation, morphology and morphometry is also demonstrated. Furthermore, applications of CASA are provided for improved mammalian sperm quality assessment, evaluation of sperm functionality and the effect of different chemical substances or pathologies on sperm fertilising ability. It is clear that CASA has evolved significantly and is currently superior to many manual techniques in the research and clinical setting.

AB - PURPOSE: To determine the prevalence of hepatitis C virus (HCV) and identify related risk factors among inmates in Quebec provincial prisons. METHODS: Anonymous cross-sectional data were collected between May 2014 and March 2015 for 1315 men and 250 women who completed a questionnaire and provided oral fluid samples. RESULTS: The global prevalence of HCV infection was 11.9% in male participants and 19.2% in female participants (P = .003). Among people who inject drugs (PWID), the prevalence was much higher compared to that in persons who does not: 51.0% versus 2.4% in men (P < .001) and 61.4% versus 2.8% in women (P < .001). In the multivariable analysis, lifetime history of injection drug use was the most important risk factor for HCV infection (adjusted odds ratio [AOR]: 14.2; 95% confidence interval [95% CI]: 9.5-21.4), with needle sharing significantly associated with HCV among PWID (AOR: 1.4; 95% CI: 1.1-1.7). Tattooing in prison was frequent, especially among men (37.2%), and independently associated with HCV infection among non-PWID (AOR: 2.8; 95% CI: 1.4-5.6). CONCLUSION: Inmates are at high risk for HCV infection especially because of a high proportion of active or past PWID among them. In addition, tattooing while in prison seems to contribute to HCV infection among non-PWID. PMID- 29576050 TI - Illustrating a "consequential" shift in the study of health inequalities: a decomposition of racial differences in the distribution of body mass. AB - PURPOSE: We present a conceptual introduction to "distributional inequalities" differences in distributions of risk factors or other outcomes between social groups-as a consequential shift for research on health inequalities. We also review a companion analytical methodology, "distributional decomposition", which can assess the population characteristics that explain distributional inequalities. METHODS: Using the 1999-2012 U.S. National Health and Nutrition Examination Survey, we apply statistical decomposition to (a) document gender specific, black-white inequalities in the distribution of body mass index (BMI) and, (b) assess the extent to which demographic (age), socioeconomic (family income, education), and behavioral predictors (caloric intake, physical activity, smoking, alcohol consumption) are associated with broader distributional inequalities in BMI. RESULTS: Black people demonstrate favorable or no different caloric intake, smoking, or alcohol consumption than whites, but worse levels of physical activity. Racial inequalities extend beyond the obesity threshold to the broader BMI distribution. Demographic, socioeconomic, and behavioral characteristics jointly explain more of the distributional inequality among men than women. CONCLUSIONS: Black-white distributional inequalities are present both among men and women, although the mechanisms may differ by gender. The notion of "distributional inequalities" offers an additional purchase for studying social inequalities in health. PMID- 29576051 TI - Editorial note. PMID- 29576052 TI - Norisoboldine, a natural aryl hydrocarbon receptor agonist, alleviates TNBS induced colitis in mice, by inhibiting the activation of NLRP3 inflammasome. AB - Although the etiology of inflammatory bowel disease is still uncertain, increasing evidence indicates that the excessive activation of NLRP3 inflammasome plays a major role. Norisoboldine (NOR), an alkaloid isolated from Radix Linderae, has previously been demonstrated to inhibit inflammation and IL-1beta production. The present study was to examine the effect of NOR on colitis and the underlying mechanism related to NLRP3 inflammasome activation. Our results showed that NOR alleviated colitis symptom in mice induced by 2, 4, 6-trinitrobenzene sulfonic acid (TNBS). Moreover, it significantly reduced expressions of cleaved IL-1beta, NLRP3 and cleaved Caspase-1 but not ASC in colons of mice. In THP-1 cells, NOR suppressed the expressions of NLRP3, cleaved Caspase-1 and cleaved IL 1beta but not ASC induced by lipopolysaccharide (LPS) and adenosine triphosphate (ATP). Furthermore, NOR could activate aryl hydrocarbon receptor (AhR) in THP-1 cells, inducing CYP1A1 mRNA expression, and promoting dissociation of AhR/HSP90 complexes, association of AhR and ARNT, AhR nuclear translocation, XRE reporter activity and binding activity of AhR/ARNT/XRE. Both siAhR and alpha naphthoflavone (alpha-NF) markedly diminished the inhibition of NOR on NLRP3 inflammasome activation. In addition, NOR elevated Nrf2 level and reduced ROS level in LPS- and ATP-stimulated THP-1 cells, which was reversed by either siAhR or alpha-NF treatment. Finally, correlations between activation of AhR and attenuation of colitis, inhibition of NLRP3 inflammasome activation and up regulation of Nrf2 level in colons were validated in mice with TNBS-induced colitis. Taken together, NOR ameliorated TNBS-induced colitis in mice through inhibiting NLRP3 inflammasome activation via regulating AhR/Nrf2/ROS signaling pathway.

AB - Given the limited studies and conflicting findings, the transport character of ginsenosides crossing the blood-brain barrier (BBB) remains unclear. The present study was designed to qualitatively determine the distribution of ginsenosides in brain tissues after oral administration of ginseng total saponins, using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) combined with immunohistochemistry. In brain tissue homogenates, ginsenoside Rg1 was detectable and no other ginsenosides or their metabolites were found. No ginsenosides were detected in cerebrospinal fluid. Immunohistochemistry staining of brain tissue sections by using anti-ginsenoside polyclonal antibodies revealed the localization of ginsenosides in brain tissues. Furthermore, immunofluorescence double staining revealed that ginsenosides widely existed in vascular endotheliocytes and astrocytes, and in few neurons. These results indicated that Rg1 was the main component that entered the brain after oral administration of ginseng total saponins and that ginsenosides could cross the BBB, although the transport capability of ginsenosides through the BBB may be poor. PMID- 29576054 TI - Salvianolic acid A attenuates ischemia reperfusion induced rat brain damage by protecting the blood brain barrier through MMP-9 inhibition and anti inflammation. AB - Salvianolic acid A (SAA) is a water-soluble component from the root of Salvia Miltiorrhiza Bge, a traditional Chinese medicine, which has been used for the treatment of cerebrovascular diseases for centuries. The present study aimed to determine the brain protective effects of SAA against cerebral ischemia reperfusion injury in rats, and to figure out whether SAA could protect the blood brain barrier (BBB) through matrix metallopeptidase 9 (MMP-9) inhibition. A focal cerebral ischemia reperfusion model was induced by middle cerebral artery occlusion (MCAO) for 1.5-h followed by 24-h reperfusion. SAA was administered intravenously at doses of 5, 10, and 20 mg.kg-1. SAA significantly reduced the infarct volumes and neurological deficit scores. Immunohistochemical analyses showed that SAA treatments could also improve the morphology of neurons in hippocampus CA1 and CA3 regions and increase the number of neurons. Western blotting analyses showed that SAA downregulated the levels of MMP-9 and upregulated the levels of tissue inhibitor of metalloproteinase 1 (TIMP-1) to attenuate BBB injury. SAA treatment significantly prevented MMP-9-induced degradation of ZO-1, claudin-5 and occludin proteins. SAA also prevented cerebral NF-kappaB p65 activation and reduced inflammation response. Our results suggested that SAA could be a promising agent to attenuate cerebral ischemia reperfusion injury through MMP-9 inhibition and anti-inflammation activities.

AB - Buyang Huanwu Decoction (BYHWD) is a well-known traditional Chinese medicine prescription which is used to treat ischaemic stroke and stroke-induced disabilities. However, the exact mechanism underlying BYHWD's amelioration of ischaemic stroke and its effective constituents remain unclear. The present study aimed to identify the effective constituents of BYHWD and to further explore its action mechanisms in the amelioration of ischaemic stroke by testing the activities of 15 absorbable chemical constituents of BYHWD with the same methods under the same conditions. The following actions of these 15 compounds were revealed: 1) Ferulic acid, calycosin, formononetin, astrapterocarpan-3-O-beta-D glucoside, paeonol, calycosin-7-O-beta-D-glucoside, astraisoflavan-7-O-beta-D glucoside, ligustrazine, and propyl gallate significantly suppressed concanavalin A (Con A)-induced T lymphocyte proliferation; 2) Propyl gallate, calycosin-7-O beta-D-glucoside, paeonol, and ferulic acid markedly inhibited LPS-induced apoptosis in RAW264.7 cells; 3) Propyl gallate and formononetin significantly inhibited LPS-induced NO release; 4) Hydroxysafflor yellow A and inosine protected PC12 cells against the injuries caused by glutamate; and 5) Formononetin, astragaloside IV, astraisoflavan-7-O-beta-D-glucoside, inosine, paeoniflorin, ononin, paeonol, propyl gallate, ligustrazine, and ferulic acid significantly suppressed the constriction of the thoracic aorta induced by KCl in rats. In conclusion, the results from the present study suggest that BYHWD exerts its ischaemic stroke ameliorating activities by modulating multiple targets with multiple components. PMID- 29576056 TI - Brazilin and Caesalpinia sappan L. extract protect epidermal keratinocytes from oxidative stress by inducing the expression of GPX7. AB - Caesalpinia sappan L., belonging to the family Leguminosae, is a medicinal plant that is distributed in Southeast Asia. The dried heartwood of this plant is used as a traditional ingredient of food, red dyes, and folk medicines in the treatment of diarrhea, dysentery, tuberculosis, skin infections, and inflammation. Brazilin is the major active compound, which has exhibited various pharmacological effects, including anti-platelet activity, anti-hepatotoxicity, induction of immunological tolerance, and anti-inflammatory and antioxidant activities. The present study aimed to evaluate the antioxidant activity and expression of antioxidant enzymes of C. sappan L. extract and its major compound, brazilin, in human epidermal keratinocytes exposed to UVA irradiation. Our results indicated that C. sappan L. extract reduced UVA-induced H2O2 production via GPX7 activation. Moreover, brazilin exhibited antioxidant effects that were similar to those of C. sappan L. via glutathione peroxidase 7 (GPX7), suggesting that C. sappan L. extract and its natural compound represent potential treatments for oxidative stress-induced photoaging of skin. PMID- 29576057 TI - Construction of a mutant of Actinoplanes sp. N902-109 that produces a new rapamycin analog. AB - In the present study, we introduced point mutations into Ac_rapA which encodes a polyketide synthase responsible for rapamycin biosynthesis in Actinoplanes sp. N902-109, in order to construct a mutant with an inactivated enoylreductase (ER) domain, which was able to synthesize a new rapamycin analog. Based on the homologous recombination induced by double-strand breaks in chromosome mediated by endonuclease I-SceI, the site-directed mutation in the first ER domain of Ac_rapA was introduced using non-replicating plasmid pLYERIA combined with an I SceI expression plasmid. Three amino acid residues of the active center, Ala-Gly Gly, were converted to Ala-Ser-Pro. The broth of the mutant strain SIPI-027 was analyzed by HPLC and a new peak with the similar UV spectrum to that of rapamycin was found. The sample of the new peak was prepared by solvent extraction, column chromatography, and crystallization methods. The structure of new compound, named as SIPI-rapxin, was elucidated by determining and analyzing its MS and NMR spectra and its biological activity was assessed using mixed lymphocyte reaction (MLR). An ER domain-deficient mutant of Actinoplanes sp. N902-109, named as SIPI 027, was constructed, which produced a novel rapamycin analog SIPI-rapxin and its structure was elucidated to be 35, 36-didehydro-27-O-demethylrapamycin. The biological activity of SIPI-rapxin was better than that of rapamycin. In conclusion, inactivation of the first ER domain of rapA, one of the modular polyketide synthase responsible for macro-lactone synthesis of rapamycin, gave rise to a mutant capable of producing a novel rapamycin analog, 35, 36-didehydro 27-O-demethylrapamycin, demonstrating that the enoylreductase domain was responsible for the reduction of the double bond between C-35 and C-36 during rapamycin synthesis. PMID- 29576058 TI - Antioxidant xanthones and anthraquinones isolated from a marine-derived fungus Aspergillus versicolor. AB - Chemical examination of an EtOAc extract of cultured Aspergillus versicolor fungus from deep-sea sediments resulted in the isolation of four xanthones, eight anthraquinones and five alkaloids, including a new xanthone, oxisterigmatocystin D (1) and a new alkaloid, aspergillusine A (13). High resolution electron impact mass spectrometry (HR-EI-MS), FT-IR spectroscopy, and NMR techniques were used to elucidate the structures of these compounds, and the absolute configuration of compound 1 was established by its NMR features and coupling constant. Furthermore, the biosynthesis pathway of these xanthones and anthraquinones were deduced, and their antioxidant activity and cytotoxicity in human cancer cell lines (HTC-8, Bel-7420, BGC-823, A549, and A2780) were evaluated. The trolox equivalent antioxidant capacity (TEAC) assay indicated most of the xanthones and anthraquinones possessing moderate antioxidant activities. The Nrf2-dependent luciferase reporter gene assay revealed that compounds 6, 7, 9, and 12 potentially activated the expression of Nrf2-regulated gene. In addition, compounds 5 and 11 showed weak cytotoxicity on A549 with the IC50 values of 25.97 and 25.60 MUmol.L-1, respectively. PMID- 29576059 TI - Sedative and antinociceptive activities of two new sesquiterpenes isolated from Ricinus communis. AB - Two new sesquiterpenes, trivially named ricinusoids A (1) and ricinusoids B (2), were isolated from ethyl acetate fraction of Ricinus communis. The structures of new compounds were elucidated by detailed spectroscopic techniques, including 1D- and 2D-NMR, UV, IR spectroscopy, and mass spectrometry. The compounds (1-2) were also assessed for in-vivo sedative and analgesic like effects in open field and acetic acid induced writhing tests respectively at 5, 10, and 20 mg.kg-1 i.p. Pretreatment of both test compounds caused significant (P <= 0.05) reduction in locomotive activity like sedative agents and abdominal constrictions like analgesics. Both compounds (1-2) possessed marked sedative and antinociceptive effects in animal models. PMID- 29576060 TI - Discovery of novel limonin derivatives as potent anti-inflammatory and analgesic agents. AB - Novel series of limonin derivatives (V-A-1-V-A-8, V-B-1-V-B-8) were synthesized by adding various tertiary amines onto the C (7)-position of limonin. The synthesized compounds possessed favorable physicochemical property, and the intrinsic solubility of the novel compounds were significantly improved, compared with limonin. Different pharmacological models were used to evaluate the analgesic and anti-inflammatory activities of the target compounds. Compound V-A 8 exhibited the strongest in vivo activity among the novel limonin analogs; its analgesic activity was more potent than aspirin and its anti-inflammatory activity was stronger than naproxen under our testing conditions.

(2016) 120-127.]. PMID- 29576062 TI - Phytic acid transport in Phaseolus vulgaris: A new low phytic acid mutant in the PvMRP1 gene and study of the PvMRPs promoters in two different plant systems. AB - Phytic acid (InsP6) is the main storage form of phosphate in seeds. In the plant it plays an important role in response to environmental stress and hormonal changes. InsP6 is a strong chelator of cations, reducing the bioavailability of essential minerals in the diet. Only a common bean low phytic acid (lpa1) mutant, affected in the PvMRP1 gene, coding for a putative tonoplastic phytic acid transporter, was described so far. This mutant is devoid of negative pleiotropic effects normally characterising lpa mutants. With the aim of isolating new common bean lpa mutants, an ethyl methane sulfonate mutagenized population was screened, resulting in the identification of an additional lpa1 allele. Other putative lpa lines were also isolated. The PvMRP2 gene is probably able to complement the phenotype of mutants affected in the PvMRP1 gene in tissues other than the seed. Only the PvMRP1 gene is expressed at appreciable levels in cotyledons. Arabidopsis thaliana and Medicago truncatula transgenic plants harbouring 1.5 kb portions of the intergenic 5' sequences of both PvMRP genes, fused upstream of the GUS reporter, were generated. GUS activity in different organs suggests a refined, species-specific mechanisms of regulation of gene expression for these two PvMRP genes. PMID- 29576063 TI - Review on the significance of chlorine for crop yield and quality. AB - The chloride concentration in the plant determines yield and quality formation for two reasons. First, chlorine is a mineral nutrient and deficiencies thereof induce metabolic problems that interfere with growth. However, due to low requirement of most crops, deficiency of chloride hardly appears in the field. Second, excess of chloride, an event that occurs under chloride-salinity, results in severe physiological dysfunctions impairing both quality and yield formation. The chloride ion can effect quality of plant-based products by conferring a salty taste that decreases market appeal of e.g. fruit juices and beverages. However, most of the quality impairments are based on physiological dysfunctions that arise under conditions of chloride-toxicity: Shelf life of persimmon is shortened due to an autocatalytic ethylene production in fruit tissues. High concentrations of chloride in the soil can increase phyto-availability of the heavy metal cadmium, accumulating in wheat grains above dietary intake thresholds. When crops are cultivated on soils that are moderately salinized by chloride, nitrate fertilization might be a strategy to suppress uptake of chloride by means of an antagonistic anion-anion uptake competition. Overall, knowledge about proteins that catalyse chloride-efflux out of the roots or that restrict xylem loading is needed to engineer more resistant crops. PMID- 29576064 TI - A comparison between genotyping-by-sequencing and array-based scoring of SNPs for genomic prediction accuracy in winter wheat. AB - The utilization of DNA molecular markers in plant breeding to maximize selection response via marker-assisted selection (MAS) and genomic selection (GS) has revolutionized plant breeding. A key factor affecting GS applicability is the choice of molecular marker platform. Genotyping-by-sequencing scored SNPs (GBS scored SNPs) provides a large number of markers, albeit with high rates of missing data. Array scored SNPs are of high quality, but the cost per sample is substantially higher. The objectives of this study were 1) compare GBS-scored SNPs, and array scored SNPs for genomic selection applications, and 2) compare estimates of genomic kinship and population structure calculated using the two marker platforms. SNPs were compared in a diversity panel consisting of 299 hard winter wheat (Triticum aestivum L.) accessions that were part of a multi-year, multi-environments association mapping study. The panel was phenotyped in Ithaca, Nebraska for heading date, plant height, days to physiological maturity and grain yield in 2012 and 2013. The panel was genotyped using GBS-scored SNPs, and array scored SNPs. Results indicate that GBS-scored SNPs is comparable to or better than Array-scored SNPs for genomic prediction application. Both platforms identified the same genetic patterns in the panel where 90% of the lines were classified to common genetic groups. Overall, we concluded that GBS-scored SNPs have the potential to be the marker platform of choice for genetic diversity and genomic selection in winter wheat. PMID- 29576065 TI - Facilitated citrate-dependent iron translocation increases rice endosperm iron and zinc concentrations. AB - Iron deficiency affects one third of the world population. Most iron biofortification strategies have focused on genes involved in iron uptake and storage but facilitating internal long-distance iron translocation has been understudied for increasing grain iron concentrations. Citrate is a primary iron chelator, and the transporter FERRIC REDUCTASE DEFECTIVE 3 (FRD3) loads citrate into the xylem. We have expressed AtFRD3 in combination with AtNAS1 (NICOTIANAMINE SYNTHASE 1) and PvFER (FERRITIN) or with PvFER alone to facilitate long-distance iron transport together with efficient iron uptake and storage in the rice endosperm. The citrate and iron concentrations in the xylem sap of transgenic plants increased two-fold compared to control plants. Iron and zinc levels increased significantly in polished and unpolished rice grains to more than 70% of the recommended estimated average requirement (EAR) for iron and 140% of the recommended EAR for zinc in polished rice grains. Furthermore, the transformed lines showed normal phenotypic growth, were tolerant to iron deficiency and aluminum toxicity, and had grain cadmium levels similar to control plants. Together, our results demonstrate that deploying FRD for iron biofortification has no obvious anti-nutritive effects and should be considered as an effective strategy for reducing human iron deficiency anemia. PMID- 29576066 TI - OsERF71 confers drought tolerance via modulating ABA signaling and proline biosynthesis. AB - Plants have evolved multiple protective strategies to adapt to adverse environmental conditions. Upland rice (UR) has evolved as a "drought-resistant type". However, little is known about genes or mechanisms in UR that underlying drought tolerance at the molecular level. Here we report isolation and functional characterization of the ERF gene, OsERF71, from the UR variety, IRAT109. The expression of OsERF71 was induced by abscisic acid (ABA) and various abiotic stresses preferentially in IRAT109 under ABA, dehydration, and polyethyleneglycol (PEG) treatments. OsERF71 was verified as a nuclear-localized protein and had transcriptional activity in yeast cells. Overexpression of the OsERF71 in Nipponbare demonstrated a significant increase in tolerance to drought stress and a reduced rate of water loss. In contrast, OsERF71 interference lines were sensitive to drought stress and exhibited a higher rate of water loss. OsERF71 overexpressing lines also showed enhanced tolerance to high salinity. Moreover, OsERF71 regulated the expression of several ABA- responsive and proline biosynthesis genes under drought stress, resulting in enhanced sensitivity to exogenous ABA treatment and proline accumulation. Accordingly, we suggest that OsERF71 plays a positive role in drought stress tolerance by increasing the expression of genes associated with ABA signaling and proline biosynthesis under stress. PMID- 29576067 TI - ShCIGT, a Trihelix family gene, mediates cold and drought tolerance by interacting with SnRK1 in tomato. AB - Abiotic stress, such as drought and cold stress, have a major impact on plant growth and development. The trihelix transcription factor family plays important roles in plant morphological development and adaptation to abiotic stresses. In this study, we isolated a cold-induced gene named ShCIGT from the wild tomato species Solanum habrochaites and found that it contributes to abiotic stress tolerance. ShCIGT belongs to the GT-1 subfamily of the trihelix transcription factors. It was constitutively expressed in various tissues. Its expression was induced by multiple abiotic stresses and abscisic acid (ABA). Overexpression of ShCIGT in cultivated tomato enhanced cold and drought stress tolerance. In addition, the transgenic plants displayed a reduced sensitivity to ABA during post-germination growth. We found that ShCIGT interacts with SnRK1, an energy sensor in the metabolic signaling network, which controls plant metabolism, growth and development, and stress tolerance. Based on these data, we conclude ShCIGT may improve abiotic-stress tolerance in tomato by interacting with SnRK1. PMID- 29576068 TI - Control of Aspergillus flavus growth and aflatoxin production in transgenic maize kernels expressing a tachyplesin-derived synthetic peptide, AGM182. AB - Aspergillus flavus is an opportunistic, saprophytic fungus that infects maize and other fatty acid-rich food and feed crops and produces toxic and carcinogenic secondary metabolites known as aflatoxins. Contamination of maize with aflatoxin poses a serious threat to human health in addition to reducing the crop value leading to a substantial economic loss. Here we report designing a tachyplesin1 derived synthetic peptide AGM182 and testing its antifungal activity both in vitro and in planta. In vitro studies showed a five-fold increase in antifungal activity of AGM182 (vs. tachyplesin1) against A. flavus. Transgenic maize plants expressing AGM182 under maize Ubiquitin-1 promoter were produced through Agrobacterium-mediated transformation. PCR products confirmed integration of the AGM182 gene, while RT-PCR of maize RNA confirmed the presence of AGM182 transcripts. Maize kernel screening assay using a highly aflatoxigenic A. flavus strain (AF70) showed up to 72% reduction in fungal growth in the transgenic AGM182 seeds compared to isogenic negative control seeds. Reduced fungal growth in the AGM182 transgenic seeds resulted in a significant reduction in aflatoxin levels (76-98%). The results presented here show the power of computational and synthetic biology to rationally design and synthesize an antimicrobial peptide against A. flavus that is effective in reducing fungal growth and aflatoxin contamination in an economically important food and feed crop such as maize. PMID- 29576069 TI - Effects of GhWUS from upland cotton (Gossypium hirsutum L.) on somatic embryogenesis and shoot regeneration. AB - The WUSCHEL (WUS) gene encodes a plant-specific homeodomain-containing transcriptional regulator, which plays important roles during embryogenesis, as well as in the formation of shoot and flower meristems. Here, we isolated two homologues of Arabidopsis thaliana WUS (AtWUS), GhWUS1a_At and GhWUS1b_At, from upland cotton (Gossypium hirsutum). Domain analysis suggested that the two putative GhWUS proteins contained a highly conserved DNA-binding HOX domain and a WUS-box. Expression profile analysis showed that GhWUSs were predominantly expressed during the embryoid stage. Ectopic expression of GhWUSs in Arabidopsis could induce somatic embryo and shoot formation from seedling root tips. Furthermore, in the absence of exogenous hormone, overexpression of GhWUSs in Arabidopsis could promote shoot regeneration from excised roots, and in the presence of exogenous auxin, excised roots expressing GhWUS could be induced to produce somatic embryo. In addition, expression of the chimeric GhWUS repressor in cotton callus inhibited embryogenic callus formation. Our results show that GhWUS is an important regulator of somatic embryogenesis and shoot regeneration. PMID- 29576070 TI - Reactive oxygen species triggering systemic programmed cell death process via elevation of nuclear calcium ion level in tomatoes resisting tobacco mosaic virus. AB - Programmed cell death (PCD) plays a positive role in the systemic response of plants to pathogen resistance. It has been confirmed that local tobacco mosaic virus (TMV) infecting tomato leaves can induce systemic PCD process in root-tip tissues. But up to now the underlying physiological mechanisms are poorly understood. This study focused on the detailed investigation of the physiological responses of root-tip cells during the initiation of systemic PCD. Physiological, biochemical examination and cytological observation showed that 1 day post inoculation (dpi) of TMV inoculation there was an increase in calcium fluorescence intensity in root tip tissue cells. Then at 2 dpi, 4 dpi, 8 dpi and 15 dpi, the fluorescence intensity of calcium ion continued to increase. However, at 5 dpi, the reactive oxygen species (ROS) began to accumulate in the root-tip cells. And finally at 20 dpi, the obvious PCD reaction was detected. In addition, the experimental results also showed that the above process involved the elevation of two types of intracellular Ca2+, including cytoplasmic calcium ([Ca2+]cyt) and nuclear calcium ([Ca2+]nuc). The [Ca2+]cyt, as a pilot signal could lead to the subsequent elevation of intracellular ROS concentration. Then, the high levels of ROS stimulated an increase of [Ca2+]nuc and eventually caused PCD reactions in the root-tip tissues. In particular, the high level of nuclear calcium is an essential mediator in systemic PCD of plants. PMID- 29576071 TI - Boron deficiency inhibits root growth by controlling meristem activity under cytokinin regulation. AB - Significant advances have been made in the last years trying to identify regulatory pathways that control plant responses to boron (B) deficiency. Still, there is a lack of a deep understanding of how they act regulating growth and development under B limiting conditions. Here, we analyzed the impact of B deficit on cell division leading to root apical meristem (RAM) disorganization. Our results reveal that inhibition of cell proliferation under the regulatory control of cytokinins (CKs) is an early event contributing to root growth arrest under B deficiency. An early recovery of QC46:GUS expression after transferring B deficient seedlings to control conditions revealed a role of B in the maintenance of QC identity whose loss under deficiency occurred at later stages of the stress. Additionally, the D-type cyclin CYCD3 overexpressor and triple mutant cycd3;1-3 were used to evaluate the effect on mitosis inhibition at the G1-S boundary. Overall, this study supports the hypothesis that meristem activity is inhibited by B deficiency at early stages of the stress as it does cell elongation. Likewise, distinct regulatory mechanisms seem to take place depending on the severity of the stress. The results presented here are key to better understand early signaling responses under B deficiency. PMID- 29576072 TI - Strigolactones affect the translocation of nitrogen in rice. AB - Strigolactones (SLs) are involved in the nutrient-dependent control of plant root and shoot architecture. The total sufficient uptake of nitrogen (N), and also its appropriate distribution, is essential for the normal growth and development of plants; however, the effect of SLs on N translocation in plants remains unknown. Here, the SL-signaling mutant dwarf 3 (d3), the biosynthesis mutant dwarf 10 (d10), and wild-type (WT) rice (Oryza sativa ssp. Japonica cv. Nipponbare) were used to investigate the relationship between N nutrition and the regulatory role of SLs. Relative to WT, the d10 mutant had a higher N concentration in older leaves but a lower N concentration in younger leaves, while the d3 mutant showed a considerably lower N concentration, especially in its younger leaves under normal N levels. By contrast, both d3 and d10 mutants contained higher N in their leaves under N-deficient conditions. The 15N uptake and distribution analysis revealed that the significantly different N concentrations among the d3, d10, and WT plants only occurred in their leaves, not in their roots. Moreover, when provided with an external supply of GR24, the synthetic SLs altered the leaf N distribution of the d10 mutant but not those of the d3 mutant and WT. Together, these results suggested that the effect of SLs on plant growth and development may be linked to N translocation to different shoot tissues. PMID- 29576073 TI - Unraveling the transcriptional complexity of compactness in sistan grape cluster. AB - Yaghooti grape of Sistan is the earliest ripening grape in Iran, harvested every May annually. It is adapted to dry conditions in Sistan region and its water requirement is less than the other grape cultivars. The transcriptional complexity of this grape was studied in three stages of cluster development. Totally, 24121 genes were expressed in different cluster development steps (step 1: cluster formation, step 2: berry formation, step 3: final size of cluster) of which 3040 genes in the first stage, 2381 genes in the second stage and 2400 genes in the third stage showed a significant increase in expression. GO analysis showed that when the clusters are ripening, the activity of the nucleus, cytoplasmic, cytosol, membrane and chloroplast genes in the cluster architecture cells decreases. In contrast, the activity of the endoplasmic reticulum, vacuole and extracellular region genes enhances. When Yaghooti grape is growing and developing, some of metabolic pathways were activated in the response to biotic and abiotic stresses. Gene co-expression network reconstruction showed that AGAMOUS is a key gene in compactness of Sistan grape cluster, because it influences on expression of GA gene which leads to increase cluster length and berries size. PMID- 29576075 TI - Ectopic expression of StCBF1and ScCBF1 have different functions in response to freezing and drought stresses in Arabidopsis. AB - Solanum tuberosum potato species constitute the bulk of economically and agronomically important potato production. However, S. tuberosum is a drought- and frost-sensitive species that is incapable of acclimating to the cold. Solanum commersonii is a tuber-bearing wild potato species that exhibits greater frost and drought resistance than S. tuberosum. CBF/DREB (C-REPET BINDING FACTOR/DROUGHT RESPONSE ELEMENT BINGING FACTOR) transcription factors play important roles in response to a variety of abiotic stresses, such as cold, drought and salt stresses. To explore different functions between S. tuberosum CBF1 (StCBF1) and S. commersonii CBF1 (ScCBF1), Arabidopsis was transformed with the ScCBF1 and StCBF1 genes driven by a constitutive CaMV35S promoter. Our results reveal that the ScCBF1 transgenic lines are much more tolerant to freezing and drought than the StCBF1 transgenic lines. The development of transgenic plants was altered, resulting in dwarf phenotype with delayed flowering and thicker and additional rosette leaves. The expression levels of several COR (COLD-RESPONSIVE) genes and development-related genes, including genes that inhibited plant growth (GA2ox7, RGL3) and delayed flowering (FLC) were higher in transgenic plants. These results suggest that these two potato CBF1 play important roles in the plant response to abiotic stress and can influence plant growth and development, and ScCBF1 plays a more pronounced function than StCBF1. PMID- 29576074 TI - CsMYB5a and CsMYB5e from Camellia sinensis differentially regulate anthocyanin and proanthocyanidin biosynthesis. AB - Tea is one of the most widely consumed nonalcoholic beverages worldwide. Polyphenols are nutritional compounds present in the leaves of tea plants. Although numerous genes are functionally characterized to encode enzymes that catalyze the formation of diverse polyphenolic metabolites, transcriptional regulation of those different pathways such as late steps of the proanthcoyanidin (PA) pathway remains unclear. In this study, using different tea transcriptome databases, we screened at least 140 R2R3-MYB transcription factors (TFs) and grouped them according to the basic function domains of the R2R3 MYB TF superfamily. Among 140 R2R3 TFs, CsMYB5a and CsMYB5e were chosen for analysis because they may be involved in PA biosynthesis regulation. CsMYB5a overexpressing tobacco plants exhibited downregulated anthocyanin accumulation but a high polymeric PA content in the flowers. Overexpression of CsMYB5e in tobacco plants did not change the anthocyanin content but increased the dimethylaminocinnamaldehyde-stained PA content. RNA-seq and qRT-PCR analyses revealed that genes related to PA and anthocyanin biosynthesis pathways were markedly upregulated in both CsMYB5a- and CsMYB5e-overexpressing flowers. Three UGTs and four GSTs were identified as involved in PA and anthocyanin glycosylation and transportation in transgenic plants. These results provide new insights into the regulation of PA and anthocyanin biosynthesis in Camellia sinensis. PMID- 29576076 TI - GmHMA3 sequesters Cd to the root endoplasmic reticulum to limit translocation to the stems in soybean. AB - A single point-mutation in GmHMA3 (Glycine max heavy metal-associated ATPase; a wild type allele cloned from a low Cd-accumulated soybean) is closely associated with seed cadmium (Cd) concentration. It is linked to Cd transportation in yeast, and is primarily expressed in the roots of plants. We hypothesized that the function of GmHMA3w in soybean would be akin to that of OsHMA3 in rice, which expresses in the root tonoplast and sequestrates Cd into the root vacuole to reduce Cd translocation to the shoots and limit its accumulation in the seeds. In this study, the transient expression of the GmHMA3w-GFP fusion protein in rice mesophyll protoplasts indicated that the subcellular localization of GmHAM3w was in the endoplasmic reticulum (ER). Overexpression of GmHMA3w increased the Cd concentration in the roots, decreased the Cd concentration in the stems, and did not affect the Cd concentration in the leaves. Additionally, its overexpression did not alter the Cd concentration across the whole plant. These findings indicated that GmHMA3w does not influence the Cd uptake, but limits the translocation of Cd from the roots to the stems. GmHMA3w thus acts in metal transportation. Assessment of the subcellular distribution of Cd indicated that GmHMA3w facilitated transport of Cd from the cell wall fraction to the organelle fraction, and then sequestrated Cd into the root ER, thus limiting its translocation to the stems. Additionally, the results also suggested that the ER constitutes a site of particularly high Cd sensitively in plants. PMID- 29576077 TI - CYSTATHIONINE GAMMA-SYNTHASE activity in rice is developmentally regulated and strongly correlated with sulfate. AB - An important goal of rice cultivar development is improvement of protein quality, especially with respect to essential amino acids such as methionine. With the goal of increasing seed methionine content, we generated Oryza sativa ssp. japonica cv. Taipei 309 transgenic lines expressing a feedback-desensitized CYSTATHIONINE GAMMA-SYNTHASE from Arabidopsis thaliana (AtD-CGS) under the control of the maize ubiquitin promoter. Despite persistently elevated cystathionine gamma-synthase (CGS) activity in the AtD-CGS transgenic lines relative to untransformed Taipei, sulfate was the only sulfur-containing compound found to be elevated throughout vegetative development. Accumulation of methionine and other sulfur-containing metabolites was limited to the leaves of young plants. Sulfate concentration was found to strongly and positively correlate with CGS activity across vegetative development, irrespective of whether the activity was provided by the endogenous rice CGS or by a combination of endogenous and AtD-CGS. Conversely, the concentrations of glutathione, valine, and leucine were clearly negatively correlated with CGS activity in the same tissues. We also observed a strong decrease in CGS activity in both untransformed Taipei and the AtD-CGS transgenic lines as the plants approached heading stage. The mechanism for this downregulation is currently unknown and of potential importance for efforts to increase methionine content in rice. PMID- 29576078 TI - Wheat expansin gene TaEXPA2 is involved in conferring plant tolerance to Cd toxicity. AB - Cadmium (Cd) is a severe and toxic heavy metal pollutant that affects plant growth and development. In this study, we found that the expression of an expansin gene, TaEXPA2, was upregulated in wheat leaves under CdCl2 toxicity. We characterized the involvement of TaEXPA2 in conferring Cd tolerance. Tobacco plants overexpressing TaEXPA2 showed higher germination rate, root elongation, and biomass accumulation compared to the wild-type (WT) plants upon CdCl2 treatment. The improved photosynthetic parameters and lesser cellular damage in transgenic plants exposed to Cd compared to that in the WT plants suggest that TaEXPA2 overexpression improves Cd tolerance in plants. Furthermore, we noticed that Cd was efficiently effluxed out of the cytoplasm in the transgenic plants owing to the enhanced activities of H+-ATPase, V-ATPase, and PPase, which helped in conferring Cd tolerance. Moreover, Cd concentration and ROS accumulation were lower in the transgenic plants than in WT plants as a consequence of enhanced antioxidant enzyme activities in the former. In addition, atexpa2, an Arabidopsis mutant, exhibited lower biomass and shorter primary root compared to its WT under Cd toxicity; however, the phenotype was recovered upon expression of TaEXPA2 in these mutants. Our results demonstrate that TaEXPA2 confers tolerance to Cd toxicity. The changed absorption/transportation of Cd and the antioxidative capacity may be involved in the improved tolerance of the transgenic plants with overexpression of TaEXPA2 to CdCl2 toxicity. PMID- 29576079 TI - Genome-wide identification and expression analysis of chitinase gene family in Brassica rapa reveals its role in clubroot resistance. AB - Chitinases, a category of pathogenesis-related proteins, are responsible for catalyzing the hydrolysis of chitin into the N-acetyl-d-glucosamine. Therefore, chitinases are believed to function as a guardian against chitin-containing pathogens. Here, we examined the role of the Brassica rapa chitinase family genes in clubroot disease. A total of 33 chitinase genes were identified and grouped into five classes based on their conserved domain. They were distributed unevenly across eight chromosomes in B. rapa, and 31 of them contained few introns (<=2). In addition, the expression of these genes was organ-specific, and 14 genes were expressed differentially in response to Plasmodiophora brassicae challenge of clubroot-susceptible (CS NIL) and resistant (CR NIL) lines. Furthermore, reduced pathogen DNA content and clubroot symptoms were observed in the CS NILs after their treatment with chitin oligosaccharides 24 h prior to inoculation with P. brassicae. The findings indicate that chitinases play a crucial role in pathogen resistance of the host plants. The results offer an insight into the role of chitinase in B. rapa-P. brassicae interaction. PMID- 29576080 TI - Seasonal nitrogen cycling in temperate trees: Transport and regulatory mechanisms are key missing links. AB - Nutrient accumulation, one of the major ecosystem services provided by forests, is largely due to the accumulation and retention of nutrients in trees. This review focuses on seasonal cycling of nitrogen (N), often the most limiting nutrient in terrestrial ecosystems. When leaves are shed during autumn, much of the N may be resorbed and stored in the stem over winter, and then used for new stem and leaf growth in spring. A framework exists for understanding the metabolism and transport of N in leaves and stems during winter dormancy, but many of the underlying genes remain to be identified and/or verified. Transport of N during seasonal N cycling is a particularly weak link, since the physical pathways for loading and unloading of amino N to and from the phloem are poorly understood. Short-day photoperiod followed by decreasing temperatures are the environmental cues that stimulate dormancy induction, and nutrient remobilization and storage. However, beyond the involvement of phytochrome, very little is known about the signal transduction mechanisms that link environmental cues to nutrient remobilization and storage. We propose a model whereby nutrient transport and sensing plays a major role in source-sink transitions of leaves and stems during seasonal N cycling. PMID- 29576081 TI - SELENOPROTEIN O is a chloroplast protein involved in ROS scavenging and its absence increases dehydration tolerance in Arabidopsis thaliana. AB - The evolutionary conserved family of Selenoproteins performs redox-regulatory functions in bacteria, archaea and eukaryotes. Among them, members of the SELENOPROTEIN O (SELO) subfamily are located in mammalian and yeast mitochondria, but their functions are thus far enigmatic. Screening of T-DNA knockout mutants for resistance to the proline analogue thioproline (T4C), identified mutant alleles of the plant SELO homologue in Arabidopsis thaliana. Absence of SELO resulted in a stress-induced transcriptional activation instead of silencing of mitochondrial proline dehydrogenase, and also high elevation of Delta(1) pyrroline-5-carboxylate dehydrogenase involved in degradation of proline, thereby alleviating T4C inhibition and lessening drought-induced proline accumulation. Unlike its animal homologues, SELO was localized to chloroplasts of plants ectopically expressing SELO-GFP. The protein was co-fractionated with thylakoid membrane complexes, and co-immunoprecipitated with FNR, PGRL1 and STN7, all involved in regulating PSI and downstream electron flow. The selo mutants displayed extended survival under dehydration, accompanied by longer photosynthetic activity, compared with wild-type plants. Enhanced expression of genes encoding ROS scavenging enzymes in the unstressed selo mutant correlated with higher oxidant scavenging capacity and reduced methyl viologen damage. The study elucidates SELO as a PSI-related component involved in regulating ROS levels and stress responses. PMID- 29576082 TI - Emerging themes in heterotrimeric G-protein signaling in plants. AB - Heterotrimeric G-proteins are key signaling components involved during the regulation of a multitude of growth and developmental pathways in all eukaryotes. Although the core proteins (Galpha, Gbeta, Ggamma subunits) and their basic biochemistries are conserved between plants and non-plant systems, seemingly different inherent properties of specific components, altered wirings of G protein network architectures, and the presence of novel receptors and effector proteins make plant G-protein signaling mechanisms somewhat distinct from the well-established animal paradigm. G-protein research in plants is getting a lot of attention recently due to the emerging roles of these proteins in controlling many agronomically important traits. New findings on both canonical and novel G protein components and their conserved and unique signaling mechanisms are expected to improve our understanding of this important module in affecting critical plant growth and development pathways and eventually their utilization to produce plants for the future needs. In this review, we briefly summarize what is currently known in plant G-protein research, describe new findings and how they are changing our perceptions of the field, and discuss important issues that still need to be addressed. PMID- 29576083 TI - Sugar metabolism in the desiccation tolerant grass Oropetium thomaeum in response to environmental stresses. AB - Oropetium thomaeum is a desiccation tolerant grass and acquisition of desiccation tolerance is correlated with changes in carbohydrate metabolism. Here we address the question whether the changes in carbohydrate metabolism are specific to the dehydration process or whether other environmental factors such as high temperature, low temperature, hypoxia, salinity or exogenous ABA application trigger the same or different changes in the sugar metabolism. Fifteen different sugar metabolites were identified by GC/MS, including erythritol, arabinose, fructose, galactose, glucose, myo-inositol, sedoheptulose, sucrose, trehalose, galactinol, maltose, raffinose, manninotriose and stachyose. Together with starch, these sugars were placed into the pathways of sucrose metabolism and raffinose family oligosaccharides (RFOs) metabolism, as well as into the group of rare sugars. By comparing the changes of sugars under various stresses, we concluded that the changes in the sugar metabolism are both convergent and divergent in response to different stresses. Except for the general response to stress, such as starch degradation, the changes of specific sugar metabolites reflect a stress-specific response of O. thomaeum. Erythritol seems to be specific for dehydration, myo-inositol for salt stress and trehalose for hypoxia stress. Similar as dehydration, low temperature, salt stress and ABA application resulted in the accumulation of sucrose and RFOs in O. thomaeum, which indicates that these stresses share high similarity with dehydration. Thus it is proposed that sucrose and RFOs have a general protective role under these stresses. In contrast sucrose and RFOs did not accumulate in response to high temperature or hypoxia whose effects tend to be consumptive and destructive. The accumulation of galactose, melibiose and manninotriose demonstrate that RFOs are degraded under stress. The accumulation of these sugar metabolites might result from the reaction of RFOs and stress-produced hydroxyl radicals, which supports a possible role of RFOs in stress defense. In addition, ABA application led to substantial synthesis of stachyose which occurs only in response to dehydration, indicating that stachyose synthesis is possibly closely related to ABA in O. thomaeum. PMID- 29576084 TI - Mechanism of freeze-thaw injury and recovery: A cool retrospective and warming up to new ideas. AB - Understanding cellular mechanism(s) of freeze-thaw injury (FTI) is key to the efforts for improving plant freeze-tolerance by cultural methods or molecular/genetic approaches. However, not much work has been done in the last 25+ years to advance our understanding of the nature and cellular loci of FTI. Currently, two FTI lesions are predominantly implicated: 1) structural and functional perturbations in plasma membrane; 2) ROS-induced oxidative damage. While both have stood the test of time, many questions remain unresolved and other potentially significant lesions need to be investigated. Additionally, molecular mechanism of post-thaw recovery (PTR), a critical component of frost survival, has not been well investigated. Mechanistic understanding of repair after reversible injury could expand the options for strategies to improve frost hardiness. In this review, without claiming to be exhaustive, I have attempted to synthesize major discoveries from last several decades on the mechanisms of FTI and the relatively little research conducted thus far on PTR mechanisms. It is followed by proposing of hypotheses for mechanism(s) for irreversible FTI or PTR involving cytosolic calcium and ROS signaling. Perspective is presented on some unresolved questions and research on new ideas to fill the knowledge gaps and advance the field. PMID- 29576085 TI - SsSm1, a Cerato-platanin family protein, is involved in the hyphal development and pathogenic process of Sclerotinia sclerotiorum. AB - The filamentous fungus Sclerotinia sclerotiorum is an important plant pathogen with a worldwide distribution. It can infect a wide variety of plants, causing serious disease in many types of crops, such as rapeseed, sunflower and soybean. Sclerotinia stem rot caused by this fungus affects main crops and has led to great economic loss. Elicitors are a group of compounds that inspire the host plant to produce an immune response against invading pathogens. This study describes a protein that has high homology with the Trichoderma elicitor Sm1 and was found in the genome of S. sclerotiorum. We named this protein SsSm1. To determine whether this protein has an elicitor function like its homology protein, we constructed a heterologous expression vector for SsSm1 and expressed it in Escherichia coli. The protein of heterologous expression led to the formation of lesions in tobacco that closely resemble hypersensitive response lesions. Transient expression of the encoding gene of SsSm1 in tobacco leaves also caused hypersensitive response. Then, RNA silencing was used to identify the function of SsSm1. The hyphal growth and pathogenicity of silenced transformants were shown to be obviously lagging and branched abnormally. Transformants produced less infection cushions and deformed sclerotiorum. In addition, SsSm1 silencing caused weak tolerance to NaCl, sorbitol and SDS, and the sensitivity of mutants to carbendazim was also significantly decreased. Based on the above results, we speculate that this protein may be related to the development of hyphae, infection cushions and sclerotiorum, but the specific molecular mechanism needs to be studied further. PMID- 29576086 TI - PAMP-responsive ATL gene StRFP1 and its orthologue NbATL60 positively regulate Phytophthora infestans resistance in potato and Nicotiana benthamiana. AB - Ubiquitination is a post-translational modification that plays a crucial role during the regulation of plant immune signalling. The plant ATL family consists of a large number of putative RING type ubiquitin ligases. We show that potato ATL family gene StRFP1 and its orthologue NbATL60 from N. benthamiana both respond to Phytophthora infestans culture filtrate (CF) and flg22 induction. StRFP1 positively regulates immunity against P. infestans in potato. Ectopic transient expression of StRFP1 or expression of NbATL60 in N. benthamiana also enhances late blight resistance. By contrast, silencing NbATL60 in N. benthamiana reduces late blight resistance and leads to plant growth inhibition. Both StRFP1 and NbATL60 localize to the plasma membrane and intracellular puncta and possess E3 Ligase activity in vitro. Furthermore we demonstrate that the RING finger domain mutants of StRFP1 and NbATL60 lost E3 ligase activity and fail to suppress P. infestans colonization in N. benthamiana, indicating that E3 ligase activity is critical for StRFP1 and NbATL60 to regulate immunity. Overexpression or RNA interference of StRFP1 in transgenic potato led to increased or decreased expression of PTI maker genes (WRKY7, WRKY8, ACRE31 and Pti5) respectively. Similarly silencing of NbATL60 in N. benthamiana decreases expression of these PTI marker genes. Moreover, VIGS of NbATL60 in N. benthamiana did not compromise P. infestans PAMP INF1 or R2/Avr2, R3a/AVR3a, Rx/Cp and Pto/AvrPto triggered cell death. These results indicate that ATL genes StRFP1 and NbATL60 contribute to basal immunity (PTI) in Solanaceous plants. PMID- 29576087 TI - Expression of OsWNK9 in Arabidopsis conferred tolerance to salt and drought stress. AB - With No Lysine (WNK) kinase belongs to ser/thr protein kinase group in which conserved catalytic lysine (K) residue of subdomain II is shifted to subdomain I. In this study, we cloned full-length coding region of WNK9 from Oryza sativa (OsWNK9) and performed in silico studies to confirm the presence of all kinase signature regulatory elements. The transcript analysis revealed that OsWNK9 was strongly down regulated under salinity, drought and ABA stress in shoots. Constitutive expression of OsWNK9 in Arabidopsis thaliana imparted increased tolerance to salt, drought, and ABA stress. Transgenic lines showed healthy phenotypes such as green leaves, achieved higher fresh weight and longer roots under salt, drought and ABA stress as compared to wild-type (WT). Transgenic plants showed better seed germination, higher chlorophyll retention and less water loss under salt and drought stress compared to WT. Promoter/gene expression studies revealed that OsWNK9 were expressed throughout plant tissues with higher expression in roots. Subcellular localization studies of OsWNK9 showed their presence in the nucleus. The transcript analysis of abiotic stress marker genes and ABA dependent genes showed they were highly expressed in transgenic lines compared to WT in response to salt and drought stress. The endogenous ABA level under salt and drought stress in transgenic lines was higher than WT. The results indicated that OsWNK9 may regulate salt and drought response in ABA dependent manner. PMID- 29576088 TI - Review: Potential biotechnological assets related to plant immunity modulation applicable in engineering disease-resistant crops. AB - This review emphasizes the biotechnological potential of molecules implicated in the different layers of plant immunity, including, pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI), effector-triggered susceptibility (ETS), and effector-triggered immunity (ETI) that can be applied in the development of disease-resistant genetically modified (GM) plants. These biomolecules are produced by pathogens (viruses, bacteria, fungi, oomycetes) or plants during their mutual interactions. Biomolecules involved in the first layers of plant immunity, PTI and ETS, include inhibitors of pathogen cell-wall-degrading enzymes (CWDEs), plant pattern recognition receptors (PRRs) and susceptibility (S) proteins, while the ETI-related biomolecules include plant resistance (R) proteins. The biomolecules involved in plant defense PTI/ETI responses described herein also include antimicrobial peptides (AMPs), pathogenesis-related (PR) proteins and ribosome-inhibiting proteins (RIPs), as well as enzymes involved in plant defensive secondary metabolite biosynthesis (phytoanticipins and phytoalexins). Moreover, the regulation of immunity by RNA interference (RNAi) in GM disease-resistant plants is also considered. Therefore, the present review does not cover all the classes of biomolecules involved in plant innate immunity that may be applied in the development of disease-resistant GM crops but instead highlights the most common strategies in the literature, as well as their advantages and disadvantages. PMID- 29576089 TI - OsDSSR1, a novel small peptide, enhances drought tolerance in transgenic rice. AB - Small signaling peptides play important roles in plant development and responses to abiotic and biotic stresses. We have identified a novel small peptide gene in rice, OsDSSR1, which is expressed mainly in the root, stem, node, leaf, and panicle. OsDSSR1 expression is also induced by drought, salinity, ABA, and H2O2 treatment. OsDSSR1 is localized in the nucleus and cytoplasm. Transgenic plants overexpressing OsDSSR1 exhibited enhanced drought stress tolerance and decreased ABA sensitivity as compared to the wild type. Overexpression of OsDSSR1 promoted the accumulation of compatible osmolytes, such as free proline and soluble sugars. OsDSSR1-overexpressing plants displayed enhanced OsSodCc2 and OscAPX expression and superoxide dismutase and ascorbate peroxidase activities under drought stress. RNA-sequencing data revealed that the expression of 72 abiotic stress-responsive genes was significantly altered in homozygous transgenic plants. These stress-responsive candidate genes will aid in expanding our understanding of the mechanisms by which small peptides mediate tolerance in crop species.

PMID- 29576090 TI - Morphological, transcriptomics and biochemical characterization of new dwarf mutant of Brassica napus. AB - Plant height is a key trait of plant architecture, and is responsible for both yield and lodging resistance in Brassica napus. A dwarf mutant line (bnaC.dwf) was obtained by chemical mutagenesis of an inbred line T6. However, the molecular mechanisms and changed biological processes of the dwarf mutant remain to be determined. In this study, a comparative transcriptome analysis between bnaC.dwf and T6 plants was performed to identify genome-wide differentially expressed genes (DEGs) and possible biological processes that may explain the phenotype variations in bnaC.dwf. As a result of this analysis, 60,134,746-60,301,384 clean reads were aligned to 60,074 genes in the B. napus genome, and accounted for 60.03% of the annotated genes. In total, 819 differentially expressed genes were used for GO (Gene Ontology) term and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment analyses with a FDR (false discovery rate) criterion of <0.001, |log2Ratio| >= 1. We focused on plant hormone signal transduction pathways, plant-pathogen interaction pathway, protein phosphorylation and degradation pathways and sugar metabolism pathways. Taken together, the decrease in local auxin (IAA) levels, the variation in BnTCH4, BnKAN1, BnERF109, COI1-JAZ9 MYC2, auxin response genes (BnGH3.11, BnSAUR78, and AUX/IAA19), and ABA (abscisic acid) signaling genes (BnADP5, BnSnRK2.1, BnABF3.1) partially accounted for variations of cell proliferation in internodes, shoot and root apical meristem maintenance, abiotic and biotic stress resistance, and pre-harvest sprouting. As a comprehensive consequence of the cross-talk between plant hormones, sugar metabolism, plant-pathogen interactions and protein metabolism, bnaC.dwf presents distinct phenotypes from T6. These results will be helpful for shedding light on molecular mechanisms in the dwarf mutant, and give insight into further molecular breeding of semi-dwarf B. napus. PMID- 29576092 TI - Position of the Academy of Nutrition and Dietetics: Individualized Nutrition Approaches for Older Adults: Long-Term Care, Post-Acute Care, and Other Settings. AB - It is the position of the Academy of Nutrition and Dietetics that the quality of life and nutritional status of older adults in long-term care, post-acute care, and other settings can be enhanced by individualized nutrition approaches. The Academy advocates that as part of the interprofessional team, registered dietitian nutritionists assess, evaluate, and recommend appropriate nutrition interventions according to each individual's medical condition, desires, and rights to make health care choices. Nutrition and dietetic technicians, registered assist registered dietitian nutritionists in the implementation of individualized nutrition care, including the use of least restrictive diets. Health care practitioners must assess risks vs benefits of therapeutic diets, especially for frail older adults. Food is an essential component of quality of life; an unpalatable or unacceptable diet can lead to poor food and fluid intake, resulting in malnutrition and related negative health effects. Including older individuals in decisions about food can increase the desire to eat and improve quality of life. PMID- 29576093 TI - Academy of Nutrition and Dietetics: Revised 2017 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent, Proficient, and Expert) in Oncology Nutrition. AB - Oncology nutrition encompasses nutrition care for individuals along the cancer care continuum. Nutrition is a vital component of prevention, treatment, and healthy survivorship. The practice of an oncology registered dietitian nutritionist (RDN) reflects the setting and population served with diverse cancer diagnoses, including expanded roles and responsibilities reflecting the RDN's interests and organization's activities. Provision of nutrition services in oncology requires that RDNs have advanced knowledge in the focus area of oncology nutrition. Thus, the Oncology Nutrition Dietetic Practice Group, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, has developed Standards of Practice and Standards of Professional Performance as tools for RDNs currently in practice or interested in working in oncology nutrition, to address their current skill level and to identify areas for additional professional development in this practice area. The Standards of Practice address and apply the Nutrition Care Process and workflow elements, which are screening, assessment, diagnosis, intervention, evaluation/monitoring, and discharge planning and transitions of care. The Standards of Professional Performance consist of the following six domains of professionalism including: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements and describe three skill levels (competent, proficient, and expert) for RDNs working in oncology nutrition.

AB - QT prolongation can be attributable to various causes that can be categorised as acquired or congenital. Arrhythmias related to QT prolongation can result in clinical presentations, such as syncope and sudden cardiac death. The perioperative period presents a number of issues that may affect a patient's risk of developing polymorphic ventricular tachycardia or torsades de pointes. Although most patients may have an unremarkable perioperative course, some may have complications; this review article aims to help clinicians avoid potential complications, and to help them address treatment for perioperative issues that may occur. PMID- 29576106 TI - Emergency care of patients receiving non-vitamin K antagonist oral anticoagulants. AB - Non-vitamin K antagonist oral anticoagulants (NOACs), which inhibit thrombin (dabigatran) and factor Xa (rivaroxaban, apixaban, edoxaban) have been introduced in several clinical indications. Although NOACs have a favourable benefit-risk profile and can be used without routine laboratory monitoring, they are associated-as any anticoagulant-with a risk of bleeding. In addition, treatment may need to be interrupted in patients who need surgery or other procedures. The objective of this article, developed by a multidisciplinary panel of experts in thrombosis and haemostasis, is to provide an update on the management of NOAC treated patients who experience a bleeding episode or require an urgent procedure. Recent advances in the development of targeted reversal agents are expected to help streamline the management of NOAC-treated patients in whom rapid reversal of anticoagulation is required. PMID- 29576107 TI - Steroids in cardiac surgery: a systematic review and meta-analysis. AB - BACKGROUND: Cardiopulmonary bypass (CPB) induces a systemic inflammatory reaction that may contribute to postoperative complications. Preventing this reaction with steroids may improve outcomes. We performed a systematic review to evaluate the impact of prophylactic steroids on clinical outcomes in patients undergoing on pump cardiac surgery. METHODS: We searched MEDLINE, EMBASE, and Cochrane CENTRAL for randomised controlled trials (RCTs) comparing perioperative corticosteroid administration with a control group in adults undergoing CPB. Outcomes of interest included mortality, myocardial infarction, and new onset atrial fibrillation. We assessed the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Fifty six RCTs published between 1977 and 2015 were included in this meta-analysis. Mortality was not significantly different between groups [3.0% (215/7258 patients) in the steroid group and 3.5% (252/7202 patients) in the placebo group; relative risk (RR), 0.85; 95% confidence interval (CI), 0.71-1.01; P=0.07; I2 = 0%]. Myocardial injury was more frequent in the steroid group [8.0% (560/6989 patients), compared with 6.9% (476/6929 patients); RR, 1.17, 95% CI, 1.04-1.31; P=0.008; I2=0%]. New onset atrial fibrillation was lower in the steroid group [25.7% (1792/6984 patients) compared with 28.3% (1969/6964 patients), RR, 0.91, 95% CI, 0.86-0.96, P=0.0005, I2=43%]; this beneficial effect was limited to small trials (P for interaction <0.00001). CONCLUSIONS: After randomising 16 013 patients, steroid administration at the time of cardiac surgery had an unclear impact on mortality, increased the risk of myocardial injury, and the impact on atrial fibrillation should be viewed with caution given that large trials showed no effect. PMID- 29576108 TI - Efficacy and adverse effects of buprenorphine in acute pain management: systematic review and meta-analysis of randomised controlled trials. AB - Buprenorphine appears to have a ceiling effect on respiratory depression, but not analgesia in healthy young patients. However, the efficacy and side-effects of buprenorphine in the setting of acute pain are poorly characterized. The aim of this study was to characterize the analgesic efficacy and adverse effects of buprenorphine compared with morphine in the acute pain setting. A systematic review of five databases was performed. Randomised controlled trials (RCTs) comparing buprenorphine with morphine in acute pain management were included. Studies performed outside of the hospital setting were excluded. The a priori primary outcomes included pain, respiratory depression, and sedation. Secondary outcomes included requirement for rescue analgesia, time to rescue analgesia, nausea, vomiting, dizziness, hypotension, and pruritus. Twenty-eight RCTs with 2210 patients met the inclusion criteria. There was no difference in pain [visual analogue scale weighted mean difference (WMD)=-0.29; 95% confidence interval (CI)=-0.62 to 0.03; I2=99%; P=0.07], incidence of respiratory depression [odds ratio (OR)=2.07; 95% CI=0.78-5.51; I2=30%; P=0.14], or sedation (OR=1.44; 95% CI=0.76-2.74; I2=23%; P=0.26). There was only one secondary outcome with an overall significant difference; buprenorphine use was associated with significantly less pruritus (OR=0.31; 95% CI=0.12-0.84; I2=6%; P=0.02). Whilst a theoretical ceiling effect may exist with respect to buprenorphine and respiratory depression, in a clinical setting, it can still cause significant adverse effects on respiratory function. However, given that buprenorphine is an equally efficacious analgesic agent, it is a useful alternative opioid because of its ease of administration and reduced incidence of pruritus. PMID- 29576109 TI - Should continuous rather than single-injection interscalene block be routinely offered for major shoulder surgery? A meta-analysis of the analgesic and side effects profiles. AB - BACKGROUND: Major shoulder surgery is associated with moderate-to-severe pain, but consensus on the optimal analgesic approach is lacking. Continuous catheter based interscalene block (CISB) prolongs the analgesic benefits of its single injection counterpart (SISB), but concerns over CISB complications and difficulties in interpreting comparative evidence examining major and minor shoulder procedures simultaneously, despite their differences in postoperative pain, have limited CISB popularity. This meta-analysis evaluates the CISB analgesic role and complications compared with SISB for major shoulder surgery. METHODS: We retrieved randomised controlled trials (RCTs) comparing the effects of CISB to SISB on analgesic outcomes and side-effects after major shoulder surgery. Postoperative opioid consumption at 24 h was designated as the primary outcome. Secondary outcomes included 24-48 h opioid consumption, postoperative rest and dynamic pain scores up to 72 h, time-to-first analgesic, recovery room and hospital stay durations, patient satisfaction, postoperative nausea and vomiting, respiratory function, and block-related complications. RESULTS: Data from 15 RCTs were pooled using random-effects modelling. Compared with SISB, CISB reduced 24- and 48-h oral morphine consumption by a weighted mean difference [95% confidence interval] of 50.9 mg [-81.6, -20.2], (P=0.001) and 44.7 mg [-80.9, 8.7], (P<0.0001), respectively. Additionally, CISB provided superior rest and dynamic pain control beyond 48 h, prolonged time-to-first analgesic, enhanced satisfaction, and reduced postoperative nausea and vomiting without complications. CISB caused an 11.0-11.7% decrease in respiratory indices. Result heterogeneity was successfully explained. CONCLUSIONS: High-level evidence indicates that CISB provides superior analgesia up to 48 h after major shoulder surgery, without increasing side-effects, compared with SISB. The importance of CISB-related changes in respiratory indices is questionable. PMID- 29576110 TI - Haematoma and abscess after neuraxial anaesthesia: a review of 647 cases. AB - Although rare, spinal haematoma and abscess after central neuraxial blocks may cause severe permanent neurological injury. Optimal treatment and outcome remain unclear. In order to identify possible predisposing patient characteristics and describe the ensuing clinical course, we searched Medline, Embase, and the Cochrane Library for reports of spinal haematomas and abscesses associated with central neuraxial blocks. Extracted data included patient characteristics, symptoms, treatment, and outcome. We analysed 409 reports, including 647 patients (387 patients with spinal haematoma and 260 patients with spinal abscess). Spinal haematoma and abscess occurred predominantly after epidural anaesthesia (58% and 83%, respectively). Neurological recovery was correlated with the severity of initial neurological deficit. When decompression of spinal haematoma was delayed for >12 h after clinical diagnosis, neurological outcome was worse compared with earlier decompression (odds ratio 4.5, 95% confidence interval 2.1-9.9, P<0.001, n=163). After spinal haematoma, 47% of published patients had full recovery, 28% had partial recovery, and in 25% no recovery was observed. Good outcome after conservative management was observed in patients with mild symptoms or with spontaneous recovery during the diagnostic and therapeutic workup. After spinal abscess, 68% of reported patients recovered fully, 21% showed partial recovery, and no recovery was reported in 11%. Persistent neurological symptoms after spinal haematoma and abscess are common and correlate with the severity of initial neurological deficit. Neurological outcome seems worse when decompressive surgery of haematoma is delayed. Notwithstanding the considerable risk of selection bias and publication bias, conservative management may be feasible in patients with mild symptoms or spontaneous recovery. PMID- 29576111 TI - Systematic review and consensus definitions for the Standardised Endpoints in Perioperative Medicine (StEP) initiative: patient comfort. AB - BACKGROUND: Maximising patient comfort during and after surgery is a primary concern of anaesthetists and other perioperative clinicians, but objective measures of what constitutes patient comfort in the perioperative period remain poorly defined. The Standardised Endpoints in Perioperative Medicine initiative was established to derive a set of standardised endpoints for use in perioperative clinical trials. METHODS: We undertook a systematic review to identify measures of patient comfort used in the anaesthetic, surgical, and other perioperative literature. A multi-round Delphi consensus process that included up to 89 clinician researchers was then used to refine a recommended list of outcome measures. RESULTS: We identified 122 studies in a literature search, which were the basis for a preliminary list of 24 outcome measures and their definitions. The response rates for Delphi Rounds 1, 2, and 3 were 100% (n=22), 90% (n=79), and 100% (n=13), respectively. A final list of six defined endpoints was identified: pain intensity (at rest and during movement) at 24 h postoperatively, nausea and vomiting (0-6 h, 6-24 h, and overall), one of two quality-of-recovery (QoR) scales (QoR score or QoR-15), time to gastrointestinal recovery, time to mobilisation, and sleep quality. CONCLUSIONS: As standardised outcomes will support benchmarking and pooling (meta-analysis) of trials, one or more of these recommended endpoints should be considered for inclusion in clinical trials assessing patient comfort and pain after surgery. PMID- 29576112 TI - Videolaryngoscopy versus direct laryngoscopy for emergency orotracheal intubation outside the operating room: a systematic review and meta-analysis. AB - Videolaryngoscopy (VL) may improve the success of orotracheal intubation compared with direct laryngoscopy (DL). We performed a systematic search of PubMed, Embase, and CENTRAL databases for studies comparing VL and DL for emergency orotracheal intubations outside the operating room. The primary outcome was rate of first-pass intubation, with subgroup analyses by location, device used, clinician experience, and clinical scenario. The secondary outcome was complication rates. Data are presented as [odds ratio (95% confidence intervals); P-values]. We identified 32 studies with 15 064 emergency intubations. There was no difference in first-pass intubation with VL compared with DL [OR=1.28, (0.99 1.65); P=0.06]. First-pass intubations were increased with VL compared with DL in the intensive care unit (ICU) [2.02 (1.43-2.85); P<0.001], and similar in the emergency department or pre-hospital setting. First-pass intubations were similar with GlideScope(r), but improved with the CMAC(r) [1.32 (1.08-1.62); P=0.007] compared with DL. There was greater first-pass intubation with VL compared with DL amongst novice/trainee clinicians [OR=1.95 (1.45-2.64); P<0.001], but not amongst experienced clinicians or paramedics/nurses. There was no difference in first-pass intubation with VL compared with DL during cardiopulmonary resuscitation or trauma. VL compared with DL was associated with fewer oesophageal intubations [OR=0.32 (0.14-0.70); P=0.003], but more arterial hypotension [OR=1.49 (1.00-2.23); P=0.05]. In summary, VL compared with DL is associated with greater first-pass emergency intubation in the ICU and amongst less experienced clinicians, and reduces oesophageal intubations. However, VL is associated with greater incidence of arterial hypotension. Further trials investigating the utility of VL over DL in specific situations are required. PMID- 29576113 TI - Incidence of thrombosis in perioperative and non-operative myocardial infarction. AB - BACKGROUND: The contribution of thrombosis to the aetiology of perioperative myocardial infarction (MI) is uncertain. We used optical coherence tomography (OCT) to determine the presence of thrombus and plaque morphology in patients experiencing a perioperative MI and matched patients experiencing a non-operative MI using OCT. METHODS: We conducted a single-centre, prospective, cohort study. Thirty patients experiencing a perioperative MI and 30 matched patients experiencing a non-operative MI, without ST elevation, underwent OCT to determine the presence of thrombus and culprit lesion plaque morphology. Angiography and OCT were performed a mean of 1.93(1.09) days and 1.53(0.68) days after the onset of perioperative and non-operative MI, respectively. OCT images were evaluated by an independent core laboratory without knowledge of whether the patient had suffered a perioperative or non-operative MI. RESULTS: We identified thrombus at the culprit lesion in four of 30 patients (13.3%) who experienced a perioperative MI and in 20 of 30 patients (66.7%) who experienced a non-operative MI, P<0.01. The only non-culprit lesion with thrombus was in a perioperative MI patient who also had a culprit lesion thrombus. Perioperative and non-operative MI culprit lesions demonstrated fibroatheroma in 18 patients (60.0%) us 20 patients (66.7%), respectively (P=0.52) and thin cap fibroatheroma in one patient (3.3%) us five patients (16.7%), respectively (P=0.11). One perioperative MI patient (3.3%) suffered a cardiac death and no non-operative MI patient died during the 30-day follow-up. CONCLUSIONS: Thrombosis was less common in perioperative than non operative MI, despite similar underlying plaque morphology. PMID- 29576114 TI - Effect of goal-directed haemodynamic therapy on postoperative complications in low-moderate risk surgical patients: a multicentre randomised controlled trial (FEDORA trial). AB - BACKGROUND: The aim of this study was to evaluate postoperative complications in patients having major elective surgery using oesophageal Doppler monitor-guided goal-directed haemodynamic therapy (GDHT), in which administration of fluids, inotropes, and vasopressors was guided by stroke volume, mean arterial pressure, and cardiac index. METHODS: The FEDORA trial was a prospective, multicentre, randomised, parallel-group, controlled patient- and observer-blind trial conducted in adults scheduled for major elective surgery. Randomization and allocation were carried out by a central computer system. In the control group, intraoperative fluids were given based on traditional principles. In the GDHT group, the intraoperative goals were to maintain a maximal stroke volume, with mean arterial pressure >70 mm Hg, and cardiac index >=2.5 litres min-1 m-2. The primary outcome was percentage of patients with moderate or severe postoperative complications during the first 180 days after surgery. RESULTS: In total, 450 patients were randomized to the GDHT group (n=224) or control group (n=226). Data from 420 subjects were analysed. There were significantly fewer with complications in the GDHT group (8.6% vs 16.6%, P=0.018). There were also fewer complications (acute kidney disease, pulmonary oedema, respiratory distress syndrome, wound infections, etc.), and length of hospital stay was shorter in the GDHT group. There was no significant difference in mortality between groups. CONCLUSIONS: Oesophageal Doppler monitor-guided GDHT reduced postoperative complications and hospital length of stay in low-moderate risk patients undergoing intermediate risk surgery, with no difference in mortality at 180 days.

PMID- 29576116 TI - Persistent alteration in behavioural reactivity to a mild social stressor in rhesus monkeys repeatedly exposed to sevoflurane in infancy. AB - BACKGROUND: Socio-emotional development is the expression and management of emotions, which in non-human primates can be examined using responses toward increasing levels of threat. Damage to the limbic system alters socio-emotional development in primates. Thus, neuronal and glial cell loss caused by exposure to general anaesthesia early in infancy might also impact socio-emotional development. We recently reported that repeated sevoflurane exposure in the first month of life alters emotional behaviours at 6 months of age and impairs visual recognition memory after the first year of life in rhesus monkeys. The present study evaluated socio-emotional behaviour at 1 and 2 yr of age in those same monkeys to determine the persistence of altered emotional behaviour. METHODS: Rhesus monkeys of both sexes were exposed to sevoflurane anaesthesia three times for 4 h each time in the first 6 weeks of life. At 1 and 2 yr of age, they were tested on the human intruder task, a well-established mild acute social stressor. RESULTS: Monkeys exposed to sevoflurane as infants exhibited normal fear and hostile responses, but exaggerated self-directed (displacement) behaviours, a general indicator of stress and anxiety in non-human primates. CONCLUSIONS: Early repeated sevoflurane exposure in infant non-human primates results in an anxious phenotype that was first detected at 6 months, and persists for at least 2 yr of age. This is the first demonstration of such a prolonged impact of early anaesthesia exposure on emotional reactivity. PMID- 29576115 TI - Inhibition of RhoA reduces propofol-mediated growth cone collapse, axonal transport impairment, loss of synaptic connectivity, and behavioural deficits. AB - BACKGROUND: Exposure of the developing brain to propofol results in cognitive deficits. Recent data suggest that inhibition of neuronal apoptosis does not prevent cognitive defects, suggesting mechanisms other than neuronal apoptosis play a role in anaesthetic neurotoxicity. Proper neuronal growth during development is dependent upon growth cone morphology and axonal transport. Propofol modulates actin dynamics in developing neurones, causes RhoA-dependent depolymerisation of actin, and reduces dendritic spines and synapses. We hypothesised that RhoA inhibition prevents synaptic loss and subsequent cognitive deficits. The present study tested whether RhoA inhibition with the botulinum toxin C3 (TAT-C3) prevents propofol-induced synapse and neurite loss, and preserves cognitive function. METHODS: RhoA activation, growth cone morphology, and axonal transport were measured in neonatal rat neurones (5-7 days in vitro) exposed to propofol. Synapse counts (electron microscopy), dendritic arborisation (Golgi-Cox), and network connectivity were measured in mice (age 28 days) previously exposed to propofol at postnatal day 5-7. Memory was assessed in adult mice (age 3 months) previously exposed to propofol at postnatal day 5-7. RESULTS: Propofol increased RhoA activation, collapsed growth cones, and impaired retrograde axonal transport of quantum dot-labelled brain-derived neurotrophic factor, all of which were prevented with TAT-C3. Adult mice previously treated with propofol had decreased numbers of total hippocampal synapses and presynaptic vesicles, reduced hippocampal dendritic arborisation, and infrapyramidal mossy fibres. These mice also exhibited decreased hippocampal-dependent contextual fear memory recall. All anatomical and behavioural changes were prevented with TAT-C3 pre-treatment. CONCLUSION: Inhibition of RhoA prevents propofol-mediated hippocampal neurotoxicity and associated cognitive deficits. PMID- 29576118 TI - Association between mode of anaesthesia and severe maternal morbidity during admission for scheduled Caesarean delivery: a nationwide population-based study in Japan, 2010-2013. AB - BACKGROUND: Although the incidence of maternal mortality during Caesarean delivery remains very low, the rate of severe maternal morbidity is increasing. Improvements in obstetric anaesthetic practice have resulted in a dramatic reduction in the risk of maternal death from general anaesthesia. Less clear is whether the risk of severe maternal morbidity differs according to mode of anaesthesia for women undergoing Caesarean delivery. We analysed the association between the mode of anaesthesia and severe maternal morbidity during Caesarean delivery using a nationally representative inpatient database. METHODS: We identified 89 225 women undergoing scheduled Caesarean delivery from the Diagnosis Procedure Combination database in Japan, 2010-2013. We defined severe maternal morbidity as the presence of any life-threatening complications and identified women with severe maternal morbidity from the database. Propensity score-matched analysis was carried out to compare the odds of severe maternal morbidity between women who underwent general vs neuraxial anaesthesia. RESULTS: Of 89 225 women, 10 058 received general anaesthesia and 79 167 received neuraxial anaesthesia. In the propensity score-matched analysis with 10 046 pairs, a higher incidence of severe maternal morbidity was observed among patients receiving general (2.00%) rather than neuraxial anaesthesia (0.76%). The odds ratio of severe maternal morbidity was 2.68 (95% CI, 1.97-3.64) among women receiving general compared with neuraxial anaesthesia. CONCLUSIONS: For scheduled Caesarean delivery, general anaesthesia compared with neuraxial anaesthesia is associated with greater odds for severe maternal morbidity. However, we should be cautious with interpretation of these findings because they may be explained by confounding indications. PMID- 29576117 TI - A neurosteroid analogue with T-type calcium channel blocking properties is an effective hypnotic, but is not harmful to neonatal rat brain. AB - BACKGROUND: More than 4 million children are exposed annually to sedatives and general anaesthetics (GAs) in the USA alone. Recent data suggest that common GAs can be detrimental to brain development causing neurodegeneration and long-term cognitive impairments. Challenged by a recent US Food and Drug Administration (FDA) warning about potentially neurotoxic effects of GAs in children, there is an urgent need to develop safer GAs. METHODS: Postnatal Day 7 (P7) rat pups of both sexes were exposed to six (repeated every 2 h) injections of equipotent hypnotic doses of ketamine or the neuroactive steroid (3beta,5beta,17beta)-3 hydroxyandrostane-17-carbonitrile (3beta-OH) for 12 h. Loss of righting reflex was used to assess hypnotic properties and therapeutic index; quantitative caspase-3 immunohistochemistry was used to assess developmental neuroapoptosis; patch-clamp recordings in acute brain slices were used to assess the effects of 3beta-OH on neuronal excitability and synaptic transmission. Cognitive abilities of rats exposed to ketamine, 3beta-OH, or vehicle at P7 were assessed in young adulthood using the radial arm maze. RESULTS: The neuroactive steroid 3beta-OH has a therapeutic index similar to ketamine, a commonly used clinical GA. We report that 3beta-OH is safe and, unlike ketamine, does not cause neuroapoptosis or impair cognitive development when administered to P7 rat pups. Interestingly, 3beta-OH blocks T-type calcium channels and presynaptically dampens synaptic transmission at hypnotically-relevant brain concentrations, but it lacks a direct effect on gamma-aminobutyric acid A or glutamate-gated ion channels. CONCLUSIONS: The neurosteroid 3beta-OH is a relatively safe hypnotic that warrants further consideration for paediatric anaesthesia. PMID- 29576119 TI - Pain after orthopaedic surgery: differences in patient reported outcomes in the United States vs internationally. An observational study from the PAIN OUT dataset. AB - BACKGROUND: A previous PAIN OUT study found that American orthopaedic-surgical patients rated 'worst pain' higher than did similar European patients. This study aims to confirm these findings in a larger, international patient sample, explore whether risk factors for greater postoperative pain exist disproportionately in the American population, and confirm the findings for one procedure. METHODS: Surveyors collected patient reported outcomes (PROs) and perioperative pain management practices using PAIN OUT methodology. Most PROs used 11-point numerical rating scales (0=null, 10=worst possible). Risk factors included: female gender, younger age, high BMI, chronic pain, and opioid use before surgery. Initial analysis used a mixed patient cohort. A secondary analysis used only patients undergoing total knee replacement (TKR). Inference was based primarily on effect size using Cohen's d. RESULTS: 13,770 patients in 13 European and non-European countries (international ) and 564 patients from the United States (US) contributed data on the 1st postoperative day. Three of 11 PROs differed between the cohorts: 'worst pain' {US 7.5 (2.5) vs international 5.6 (2.8); d=0.66 [confidence interval (CI) 0.58-0.75]}; proportion 'receiving information about treatment options' [US 0.86 vs international 0.66; d=0.53 (CI 0.39-0.66)]; reporting adverse effects and their severity [US 0.87 vs international 0.73; d=0.52 (CI 0.38-0.66)]. Risk factors did not differ between the two cohorts. PROs and management patterns in TKR patients were similar to the mixed cohort. CONCLUSIONS: Three PROs differed between international and US patients, with higher 'worst pain' for US patients. Neither risk factors, nor patient mix accounted for the observed differences for 'worst pain'. CLINICAL TRIAL REGISTRATION: NCT 02083835. PMID- 29576120 TI - Pattern of perioperative gabapentinoid use and risk for postoperative naloxone administration. AB - BACKGROUND: Single preoperative gabapentinoid (gabapentin and pregabalin) administration has been associated with respiratory depression during Phase I anaesthesia recovery. In this study, we assess for associations between chronic (home) use and perioperative administration (preoperative and postoperative) of gabapentinoids, and risk for severe over-sedation or respiratory depression as inferred from the use of naloxone. METHODS: From 2011 to 2016, we identified patients undergoing general anaesthesia discharged to standard postoperative wards and administered naloxone within 48 h of surgery in a single centre. These patients were 2:1 matched on age, sex, and type of procedure. Patient and perioperative characteristics were abstracted and compared to assess for risk for naloxone administration. RESULTS: We identified 128 patients that received naloxone after operation [odds ratio 1.2; 95% confidence interval (CI) 1.0, 1.4 per 1000 general anaesthetics]. Patients on chronic or postoperative gabapentinoid therapy were at significantly higher risk for receiving naloxone after operation. Multivariable analysis detected significant interactions between chronic and postoperative use of gabapentinoids, where continuation of chronic gabapentinoid medications into the postoperative period was associated with an increased rate of naloxone administration (6.30, 95% CI 2.4, 16.7; P=0.001). Obstructive sleep apnoea (P=0.005) and preoperative disability (P=0.003) were also associated with an increased risk for postoperative naloxone administration. Patients who received naloxone had longer hospital stays and higher rates of postoperative delirium. CONCLUSIONS: Continuation of chronic gabapentinoid medications into the postoperative period is associated with the increased use of naloxone to reverse over-sedation or respiratory depression. Such patients requiring this therapy warrant high levels of postoperative monitoring. PMID- 29576121 TI - Anti-nociceptive effects of caloric restriction on neuropathic pain in rats involves silent information regulator 1. AB - BACKGROUND: Caloric restriction (CR) increases both average and maximum lifespan, retards physiological signs of ageing, and delays the onset of several diseases and may mediate neuropathic pain. Neuropathic pain seriously affects the quality of life of patients. In this study, we investigated whether CR exerts anti nociceptive effects on neuropathic pain, and probed its potential mechanisms. METHODS: Adult rats were divided into two dietary groups: an ad libitum (AL)-fed group and a CR group, which was provided with 60% of the food intake of AL rats for 6 weeks. The effects of 6-week CR on pain behaviour and neuro-inflammation induced by chronic constriction injury of the sciatic nerve were evaluated. RESULTS: Rats subjected to a CR diet had reduced hypersensitivity to mechanical and thermal stimuli after nerve-constriction injury. CR increased the silent information regulator 1 (SIRT1) expression, and suppressed the nerve-constriction induced production of mitochondrial-derived reactive oxygen species and activation of nuclear factor kappa B accompanied by suppression of mature interleukin-1beta production in the ipsilateral spinal cord dorsal horn. The inhibition of SIRT1 reversed the effects of caloric restriction on pain behaviours. Moreover, CR decreased the phosphorylation of N-methyl-d-aspartate receptor subunits and the mitogen-activated protein kinase family, decreased the sensory neurone excitability, and inhibited the nerve-constriction-induced glial cell activation. CONCLUSIONS: These results suggest that the effects of CR on pain behaviours in a rat model of nerve injury are via inhibition of excessive neuro-inflammation induced by the injury. CR may be of benefit in patients with neuropathic pain. PMID- 29576122 TI - Ketamine and norketamine attenuate oxycodone tolerance markedly less than that of morphine: from behaviour to drug availability. AB - BACKGROUND: Ketamine attenuates morphine tolerance by antagonising N-methyl-d aspartate receptors. However, a pharmacokinetic interaction between morphine and ketamine has also been suggested. The interaction between oxycodone and ketamine is unclear. We studied the effects of ketamine and norketamine on the attenuation of morphine and oxycodone tolerance focusing on both the pharmacodynamic and pharmacokinetic interactions. METHODS: Morphine 9.6 mg day-1 or oxycodone 3.6 mg day-1 was delivered to Sprague-Dawley rats by subcutaneous pumps. Once tolerance had developed, the rats received subcutaneous injections of ketamine or norketamine. Tail-flick, hot-plate, and rotarod tests were performed. Drug concentrations were measured with high-performance liquid chromatography-tandem mass spectrometry. RESULTS: Anti-nociceptive tolerance to morphine and oxycodone developed similarly by Day 6. Acute ketamine 10 mg kg-1 and norketamine 30 mg kg 1 attenuated morphine tolerance for 120 and 150 min, respectively, whereas in oxycodone-tolerant rats the effect lasted only 60 min. Both ketamine and norketamine increased the brain and serum concentrations of morphine, and inhibited its metabolism to morphine-3-glucuronide, whereas oxycodone concentrations were not changed. Morphine, but not oxycodone, pretreatment increased the brain and serum concentrations of ketamine and norketamine. Ketamine, but not norketamine, significantly impaired the motor coordination. CONCLUSIONS: Ketamine and norketamine attenuated morphine tolerance more effectively than oxycodone tolerance. Ketamine and norketamine increased morphine, but not oxycodone brain concentrations, which may partly explain this difference. Norketamine is effective in attenuating morphine tolerance with minor effects on motor coordination. These results warrant pharmacokinetic studies in patients who are co-treated with ketamine and opioids. PMID- 29576124 TI - Cutaneous innervation of the hand: clinical testing in volunteers shows high intra- and inter-individual variability. AB - BACKGROUND: Many clinicians require a solid understanding of the anatomical areas supplied by specific peripheral nerves. Virtually all pertinent medical textbooks claim that the entire (palmar and dorsal) surface of the hand is supplied by three (median, radial, and ulnar) nerves and that each of these covers a well defined area. This study was designed to evaluate the sensory-distribution pattern of peripheral nerves in the hand. METHODS: Twelve volunteers were enrolled and randomly allocated to have median, ulnar, or radial nerve blocks to each hand on three successive days. All blocks were performed using ultrasound guidance. A neurologist carried out pinprick testing to define the sensory distribution area of each procedure. The hand surface was then scanned, and the sensory-distribution area of the blocked nerve was traced, measured, and quantified in relation to the entire hand surface for descriptive and comparative statistical analyses. RESULTS: The sensory-distribution areas of the three nerves revealed a high degree of inter-individual and intra-individual variabilities. Sizeable areas were not covered by any of the three nerves, again involving great variability. Conversely, 15 of the 24 hands showed areas of overlapping supply from more than one nerve. CONCLUSIONS: Our findings suggest that the anatomical areas supplied by peripheral nerves are characterised by much greater variability than is routinely claimed. CLINICAL TRIAL REGISTRATION: DRKS00010707. PMID- 29576123 TI - Role of spinal cyclooxygenase-2 and prostaglandin E2 in fentanyl-induced hyperalgesia in rats. AB - BACKGROUND: Accumulated evidence suggests that spinal cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) may be implicated in the development of opioid induced hyperalgesia. METHODS: Rats received subcutaneous fentanyl injections at different doses (20-80 MUg kg-1), four separate times at 15-min intervals. Some rats only received fentanyl (60 MUg kg-1 * 4 doses) with or without surgical incision. Fentanyl-induced hyperalgesia was evaluated via a tail-pressure or paw withdrawal test. The concentrations of spinal COX-2, EP-1 receptor (EP-1R) mRNA, and PGE2 were measured. The effects of the COX-2 inhibitor, parecoxib (intraperitoneal 10 mg kg-1), or the EP-1R antagonist, SC51089 (intraperitoneal 100 MUg kg-1), on hyperalgesia and spinal PGE2 were examined. RESULTS: Acute repeated injections of fentanyl dose-dependently induced mechanical hyperalgesia, which reached a peak at the 1st day and persisted for 1-4 days postinjection. This hyperalgesia could be partly or totally prevented by the pretreatment of either parecoxib or SC51089. Consistently, the levels of spinal COX-2 mRNA and PGE2 were also dose-dependently increased, reaching a peak at the first day and persisting for 2 days postinjection. Pretreatment with parecoxib could block the increase in spinal PGE2 and had no effects on spinal COX-2 and EP-1R mRNA. Fentanyl injection enhanced incision-induced mechanical and thermal hyperalgesia. CONCLUSIONS: Acute repeated fentanyl administration dose-dependently produced mechanical hyperalgesia and augmented surgery induced postoperative hyperalgesia. This behavioural change was paralleled with an increase in spinal COX-2 mRNA and PGE2 after fentanyl administration. Inhibition of COX-2 or blockade of EP-1R can partly or totally prevent hyperalgesia. PMID- 29576125 TI - Single-shot pectoral plane (PECs I and PECs II) blocks versus continuous local anaesthetic infusion analgesia or both after non-ambulatory breast-cancer surgery: a prospective, randomised, double-blind trial. AB - BACKGROUND: Pectoral plane blocks (PECs) are increasingly used in analgesia for patients undergoing breast surgery, and were recently found to be at least equivalent to single-shot paravertebral anaesthesia. However, there are no data comparing PECs with the popular practice of continuous local anaesthetic wound infusion (LA infusion) analgesia for breast surgery. Therefore, we compared the efficacy and safety of PECs blocks with LA infusion, or a combination of both in patients undergoing non-ambulatory breast-cancer surgery. METHODS: This single centre, prospective, randomised, double-blind trial analysed 45 women to receive either PECs blocks [levobupivacaine 0.25%, 10 ml PECs I and levobupivacaine 0.25%, 20 ml PECs II (PECs group); LA infusion catheter (levobupivacaine 0.1% at 10 ml h-1 for 24 h (LA infusion group); or both (PECs and LA infusion)]. The primary outcome measure was area under the curve of the pain verbal rating score whilst moving vs time (AUC) over 24 h. Secondary outcomes included total opioid consumption at 24 h. RESULTS: AUC moving was mean (SD) 71 (34) mm h-1vs 58 (41) vs 23 (20) in PECs, LA infusion, and both, respectively; P=0.002. AUC at rest was also significantly lower in patients receiving both. The total 24 h opioid consumption [median (25-75%)] was 14 mg (9-26) vs 11 (8-24) vs 9 (5-11); P=0.4. No adverse events were observed. CONCLUSIONS: The combination of both pre incisional PECs blocks and postoperative LA infusion provides better analgesia over 24 h than either technique alone after non-ambulatory breast-cancer surgery. CLINICAL TRIAL REGISTRATION: NCT 03024697. PMID- 29576126 TI - Investigation into the visual perceptive ability of anaesthetists during ultrasound-guided interscalene and femoral blocks conducted on soft embalmed cadavers: a randomised single-blind study. AB - BACKGROUND: Errors may occur during regional anaesthesia whilst searching for nerves, needle tips, and test doses. Poor visual search impacts on decision making, clinical intervention, and patient safety. METHODS: We conducted a randomised single-blind study in a single university hospital. Twenty trainees and two consultants examined the paired B-mode and fused B-mode and elastography video recordings of 24 interscalene and 24 femoral blocks conducted on two soft embalmed cadavers. Perineural injection was randomised equally to 0.25, 0.5, and 1.0 ml volumes. Tissue displacement perceived on both imaging modalities was defined as 'target' or 'distractor'. Our primary objective was to test the anaesthetists' perception of the number and proportion of targets and distractors on B-mode and fused elastography videos collected during femoral and sciatic nerve block on soft embalmed cadavers. Our secondary objectives were to determine the differences between novices and experts, and between test-dose volumes, and to measure the area and brightness of spread and strain patterns. RESULTS: All anaesthetists recognised perineural spread using 0.25 ml volumes. Distractor patterns were recognised in 133 (12%) of B-mode and in 403 (38%) of fused B-mode and elastography patterns; P<0.001. With elastography, novice recognition improved from 12 to 37% (P<0.001), and consultant recognition increased from 24 to 53%; P<0.001. Distractor recognition improved from 8 to 31% using 0.25 ml volumes (P<0.001), and from 15 to 45% using 1 ml volumes (P<0.001). CONCLUSIONS: Visual search improved with fusion elastography, increased volume, and consultants. A need exists to investigate image search strategies. PMID- 29576127 TI - Evaluation of lung and chest wall mechanics during anaesthesia using the PEEP step method. AB - BACKGROUND: Postoperative pulmonary complications are common. Between patients there are differences in lung and chest wall mechanics. Individualised mechanical ventilation based on measurement of transpulmonary pressures would be a step forward. A previously described method evaluates lung and chest wall mechanics from a change of DeltaPEEP and calculation of change in end-expiratory lung volume (DeltaEELV). The aim of the present study was to validate this PEEP-step method (PSM) during general anaesthesia by comparing it with the conventional method using oesophageal pressure (PES) measurements. METHODS: In 24 lung healthy subjects (BMI 18.5-32), three different sizes of PEEP steps were performed during general anaesthesia and DeltaEELVs were calculated. Transpulmonary driving pressure (DeltaPL) for a tidal volume equal to each DeltaEELV was measured using PES measurements and compared to DeltaPEEP with limits of agreement and intraclass correlation coefficients (ICC). DeltaPL calculated with both methods was compared with a Bland-Altman plot. RESULTS: Mean differences between DeltaPEEP and DeltaPL were <0.15 cm H2O, 95% limits of agreements -2.1 to 2.0 cm H2O, ICC 0.6-0.83. Mean differences between DeltaPL calculated by both methods were <0.2 cm H2O. Ratio of lung elastance and respiratory system elastance was 0.5-0.95. CONCLUSIONS: The large variation in mechanical properties among the lung healthy patients stresses the need for individualised ventilator settings based on measurements of lung and chest wall mechanics. The agreement between DeltaPLs measured by the two methods during general anaesthesia suggests the use of the non-invasive PSM in this patient population. CLINICAL TRIAL REGISTRATION: NCT 02830516. PMID- 29576128 TI - Non-invasive positive-pressure ventilation with positive end-expiratory pressure counteracts inward air leaks during preoxygenation: a randomised crossover controlled study in healthy volunteers. AB - BACKGROUND: During preoxygenation, the lack of tight fit between the mask and the patient's face results in inward air leak preventing effective preoxygenation. We hypothesized that non-invasive positive-pressure ventilation and positive end expiratory pressure (PEEP) could counteract inward air leak. METHODS: Healthy volunteers were randomly assigned to preoxygenated through spontaneous breathing without leak (SB), spontaneous breathing with a calibrated air leak (T-shaped piece between the mouth and the breathing system; SB-leak), or non-invasive positive inspiratory pressure ventilation (inspiratory support +6 cm H2O; PEEP +5 cm H2O) with calibrated leak (PPV-leak). The volunteers breathed through a mouthpiece connected to an anaesthesia ventilator. The expired oxygen fraction (FeO2) and air-leak flow (ml s-1) were measured. The primary end point was the proportion of volunteers with FeO2 >90% at 3 min. The secondary end points were FeO2 at 3 min, time to reach FeO2 of 90%, and the inspiratory air-leak flow. RESULTS: Twenty healthy volunteers were included. The proportion of volunteers with FeO2 >90% at 3 min was 0% in the SB-leak group, 95% in the SB group, and 100% in the PPV-leak group (P<0.001). At 3 min, the mean [standard deviation (sd)] FeO2 was 89 (1)%, 76 (1)%, and 90 (0)% in the SB, SB-leak, and PPV-leak groups, respectively (P<0.001). The mean (sd) inward air leak was 59 (12) ml s-1 in the SB-leak group, but 0 (0) ml s-1 in the PPV-leak group (P<0.001). CONCLUSIONS: Preoxygenation through non-invasive positive-pressure ventilation and PEEP provided effective preoxygenation despite an inward air leak. CLINICAL TRIAL REGISTRATION: NCT03087825.

It is a benign and usually self-limiting infection, but its treatment in children can be challenging, particularly when the patient presents multiple lesions or when lesions are symptomatic or highly visible. Several treatment options exist. Choice of treatment depends on the number and location of lesions, the prior experience of the treating physician, and the preferences of the child's parents or carers. This article provides an update on treatment options for molluscum contagiosum, with a particular focus on immunocompetent pediatric patients.

AB - BACKGROUND: Optimal cardiovascular risk factors control among individuals with diabetes remains a challenge. We evaluated changes in glucose, lipid, and blood pressure control among diabetes patients after implementation of a large-scale population management program, known as Preventing Heart Attacks and Strokes Everyday, at Kaiser Permanente Northern California (KPNC), during 2004-2013. METHODS: We used National Committee for Quality Assurance Healthcare Effectiveness Data and Information Set cut points to identify prevalence of poor glycemic (hemoglobin A1c > 9%) control, good lipid control (low-density lipoprotein cholesterol < 100 mg/dL), and good blood pressure control (blood pressure < 140/90 mm Hg) in each year (N range = 98,345 to 122,177 over the entire period). We assessed trends in risk factor control based on Joinpoint regression and average annual percentage change (AAPC) compared with published National Committee for Quality Assurance Healthcare Effectiveness Data and Information Set commercial rates. RESULTS: We found that the prevalence of poor glycemic control (hemoglobin A1c > 9%) declined in both KPNC and nationally, but was statistically significant only in KPNC (AAPC = -4.8; P < .05). The prevalence of good lipid control (low-density lipoprotein cholesterol < 100 mg/dL) increased significantly in KPNC (47% to 71%; AAPC = +4.3; P < .05), but there was no significant improvement nationally (40% to 44%; AAPC = +1.4; P = .2). The prevalence of blood pressure control (<140/90 mm Hg) was higher in KPNC (77% to 82%; AAPC = +1.1; P < .05) versus nationally (57% to 62%; AAPC = +1.9; P < .05) during the reported years 2007-2013. CONCLUSIONS: Relative to national benchmarks, a substantially greater improvement in risk factor control among adults with diabetes was observed after implementation of a comprehensive population management program. PMID- 29576193 TI - Role of Salt Valency in the Switch of H-NS Proteins between DNA-Bridging and DNA Stiffening Modes. AB - This work investigates the interactions of H-NS proteins and bacterial genomic DNA through computer simulations performed with a coarse-grained model. The model was developed specifically to study the switch of H-NS proteins from the DNA stiffening to the DNA-bridging mode, which has been observed repeatedly upon addition of multivalent cations to the buffer but is still not understood. Unraveling the corresponding mechanism is all the more crucial, as the regulation properties of H-NS proteins, as well as other nucleoid proteins, are linked to their DNA-binding properties. The simulations reported here support a mechanism, according to which the primary role of multivalent cations consists in decreasing the strength of H-NS/DNA interactions compared to H-NS/H-NS interactions, with the latter ones becoming energetically favored with respect to the former ones above a certain threshold of the effective valency of the cations of the buffer. Below the threshold, H-NS dimers form filaments, which stretch along the DNA molecule but are quite inefficient in bridging genomically distant DNA sites (DNA stiffening mode). In contrast, just above the threshold, H-NS dimers form three dimensional clusters, which are able to connect DNA sites that are distant from the genomic point of view (DNA-bridging mode). The model provides clear rationales for the experimental observations that the switch between the two modes is a threshold effect and that the ability of H-NS dimers to form higher order oligomers is crucial for their bridging capabilities.

AB - BACKGROUND: The ureteral disinsertion with bladder cuff technique continues to evolve. We present the endoscopic laser transurethral technique combined with a transperitoneal and retroperitoneal laparoscopic approach in lateral decubitus, without patient repositioning, for treating urothelial carcinomas of the upper urinary tract. MATERIALS AND METHODS: We present 3 laparoscopic nephroureterectomies: 1 transperitoneal and 2 retroperitoneal. Disinsertion was performed in lateral decubitus using a flexible cystoscope and a 365-MUm holmium laser fiber. The endoscopic technique was progressively adapted to 3-port and single-port retroperitoneoscopic approaches. Before laparoscopic handling of the kidney, ureter was clamped below the tumour. The endoscopic technique was then started. Both approaches were simultaneously employed. RESULTS: Nephroureterectomies were achieved performing en bloc endoscopic disinsertion of the bladder cuff and ensuring a closed system comparable to open technique. The second case required reconversion due to technical problems and extension of the surgical time. No relapses were diagnosed during follow-up. CONCLUSION: Results are comparable to open surgery, technique ensured compliance to oncology principles, enabled disinsertion in lateral decubitus and avoid patient repositioning saving surgical time. The results reflect the benefits of minimally invasive surgery in all cases. PMID- 29576195 TI - [The Script Concordance Test: A multimodal teaching tool]. AB - In recent years, there has been a major interest in assessing learners during their medical education. The core of medical competence is the clinical reasoning that should be acquired by all medical actors. Its assessment includes the ability to integrate and apply different types of knowledge, weigh critical evidence and think about the process used to have a diagnosis. French faculties of medicine will have to include it in the training and evaluation of students during 2017. It should therefore be part of the new docimological modalities of the computerized "Epreuves Classantes Nationales" from 2020 onwards. In this article, we did a specific review of the literature concerning the theoretical foundations, methodology and use of Script Concordance Test (SCT) in the field of health. To do so, we used the PubMed, EMBASE and PsycINFO databases and selected articles in English and French language using the following keywords alone or in combination: script, concordance, script concordance test, medical studies, validity, fidelity, psychometric properties. We have found 62 articles that matched our search. Built on a well-targeted methodology, the SCT is a reliable and valid pedagogical tool. It can discriminate the levels of practice between medical students, residents and medical doctors, evaluate the progression and skills of clinical reasoning. It can be administered online, in multicentric centers, at a national or international level. There are, however, limitations that teachers must take into account.

AB - This work describes a micellar liquid chromatographic method which was developed and validated to determine simultaneously three structurally-related antiepileptic drugs; namely carbamazepine (CMZ), oxcarbazepine (OCZ) and eslicarbazepine acetate (ECZ). The analysis was achieved using a phenyl column (250mm*4.6mm i.d., 5MUm particle size), a mobile phase consisting of a mixture of 0.3% triethylamine and 10% n-butanol in a solution of 0.05M sodium dodecyl sulphate adjusted to pH 7.0 using 0.02M orthophosphoric acid. The mobile phase was pumped at a flow rate of 1.5mLmin-1 and detection was adjusted at 215nm. The method showed good linearity (r2>0.998) over the concentration ranges of 0.1-10 for CMZ and OCZ and 0.2-20MUgmL-1 for ECZ. The suggested method was successfully applied for the analysis of the studied drugs in their dosage forms and for the determination of CMZ and OCZ in spiked human urine and plasma without prior extraction. The proposed method was further extended to the analysis of real samples of plasma and urine of volunteers receiving therapy of CMZ and OCZ. Furthermore, the method was successfully applied to tablets dissolution-rate testing, and the results were satisfactory.

AB - OBJECTIVE: (1) To compare the results of graft take-up and audiological outcome of temporalis fascia versus island cartilage graft in type 1 tympanoplasty. (2) To compare the rate of postoperative retraction of neotympanum in both. METHODS: A prospective study was conducted on 70 patients of ages ranging from 11 to 50 years with dry subtotal perforation. 35 underwent island cartilage tympanoplasty and 35 underwent type 1 tympanoplasty using temporalis fascia graft. Graft acceptance rates and post-operative audiograms were compared. RESULTS: At one year follow up, the graft take-up rate for temporalis fascia and island cartilage graft were found to be 82.9% and 97.1% respectively, which was found to be statistically significant (p<0.05). In the temporalis fascia group, two out of 35 patients (5.7%) had retraction of the neo tympanum. There was no incidence of retraction using island cartilage graft. There was no significant difference in the postoperative air-bone gap gain between temporalis fascia graft and island cartilage graft. CONCLUSION: Island cartilage tympanoplasty shows a high degree of reliability in high risk cases. It has a higher graft take-up rate with no incidence of retraction of neotympanum. Moreover, it provided significant hearing improvement in our patients. PMID- 29576203 TI - ? PMID- 29576204 TI - [The image and status of the child over the centuries]. AB - Children have not always held the privileged position within the family that they enjoy today. In the predominantly rural society of the past, they belonged as much to a lineage as they did to their parents. The frailty of life was such that the need to carry on the line of descent overrode any other considerations. From the 18th century, a new concept of the family appeared, in which the child, more autonomous, became an object of attention and affection. PMID- 29576205 TI - [The evolution of places of birth]. AB - Since the beginning of the 19th century, medical advances have drastically cut the number of deaths at birth, ensuring a maximum level of safety of childbirth today. However, there is increasing demand for alternative forms of childbirth which take into account more the expectations of the future parents as well as the psychological and relational dimensions. The current experimentation involving birth centres could lead the way for the development of such possibilities from 2018. PMID- 29576206 TI - [The challenges of preparing for birth and parenthood]. AB - Pregnancy and the birth of a child represents, for the new parents, a radical change in their lives.

AB - There are a thousand and one ways of preparing to be a parent. Specific support is offered to pregnant women or the couple in order to take the time to prepare for this personal transformation. Haptonomy, sophrology, shiatsu and massage, acupuncture or gestalt therapy are some of the methods helping parents to prepare to welcome their future child with peace of mind.

AB - The arrival of a newborn in the delivery room is a precious and unique moment which caregivers support by seeing to the comfort and wellbeing of the baby and his or her parents. Developmental care is introduced early, skin-to-skin contact is favoured and invasive treatment is only performed if strictly necessary. At the same time, the teams are ready to intervene in the event of a complication. PMID- 29576209 TI - [Intervention and role of the paediatrician in the delivery room]. AB - Some newborns require the presence of a paediatrician in the delivery room, for emergency care. This generally leads to hospitalisation in neonatal intensive care or neonatology. Prematurity and respiratory distress are the main causes. These unexpected situations are a source of anxiety for the parents. It is essential that the multidisciplinary team draws on both its technical and relational expertise, in order to provide optimal treatment to the infant while supporting the parents with the necessary empathy.

AB - Upon discharge from the maternity hospital, the newborn is welcomed not only in a home but also within a family. The postnatal follow-up over the first few weeks can take several forms: a programme to support the return home, hospital at home service or follow-up by a private practice midwife or professionals from the mother and infant welfare protection service. The aim is to meet the needs of the baby, favour the establishment of the parent-baby bond and to support the construction of parenthood.

PMID- 29576217 TI - Bi-allelic Mutations in EPRS, Encoding the Glutamyl-Prolyl-Aminoacyl-tRNA Synthetase, Cause a Hypomyelinating Leukodystrophy. AB - Hypomyelinating leukodystrophies are genetic disorders characterized by insufficient myelin deposition during development. They are diagnosed on the basis of both clinical and MRI features followed by genetic confirmation. Here, we report on four unrelated affected individuals with hypomyelination and bi allelic pathogenic variants in EPRS, the gene encoding cytoplasmic glutamyl prolyl-aminoacyl-tRNA synthetase. EPRS is a bifunctional aminoacyl-tRNA synthetase that catalyzes the aminoacylation of glutamic acid and proline tRNA species. It is a subunit of a large multisynthetase complex composed of eight aminoacyl-tRNA synthetases and its three interacting proteins. In total, five different EPRS mutations were identified. The p.Pro1115Arg variation did not affect the assembly of the multisynthetase complex (MSC) as monitored by affinity purification-mass spectrometry. However, immunoblot analyses on protein extracts from fibroblasts of the two affected individuals sharing the p.Pro1115Arg variant showed reduced EPRS amounts. EPRS activity was reduced in one affected individual's lymphoblasts and in a purified recombinant protein model. Interestingly, two other cytoplasmic aminoacyl-tRNA synthetases have previously been implicated in hypomyelinating leukodystrophies bearing clinical and radiological similarities to those in the individuals we studied. We therefore hypothesized that leukodystrophies caused by mutations in genes encoding cytoplasmic aminoacyl-tRNA synthetases share a common underlying mechanism, such as reduced protein availability, abnormal assembly of the multisynthetase complex, and/or abnormal aminoacylation, all resulting in reduced translation capacity and insufficient myelin deposition in the developing brain. PMID- 29576218 TI - Mutations in PMPCB Encoding the Catalytic Subunit of the Mitochondrial Presequence Protease Cause Neurodegeneration in Early Childhood. AB - Mitochondrial disorders causing neurodegeneration in childhood are genetically heterogeneous, and the underlying genetic etiology remains unknown in many affected individuals. We identified biallelic variants in PMPCB in individuals of four families including one family with two affected siblings with neurodegeneration and cerebellar atrophy. PMPCB encodes the catalytic subunit of the essential mitochondrial processing protease (MPP), which is required for maturation of the majority of mitochondrial precursor proteins. Mitochondria isolated from two fibroblast cell lines and induced pluripotent stem cells derived from one affected individual and differentiated neuroepithelial stem cells showed reduced PMPCB levels and accumulation of the processing intermediate of frataxin, a sensitive substrate for MPP dysfunction. Introduction of the identified PMPCB variants into the homologous S. cerevisiae Mas1 protein resulted in a severe growth and MPP processing defect leading to the accumulation of mitochondrial precursor proteins and early impairment of the biogenesis of iron sulfur clusters, which are indispensable for a broad range of crucial cellular functions. Analysis of biopsy materials of an affected individual revealed changes and decreased activity in iron-sulfur cluster-containing respiratory chain complexes and dysfunction of mitochondrial and cytosolic Fe-S cluster dependent enzymes. We conclude that biallelic mutations in PMPCB cause defects in MPP proteolytic activity leading to dysregulation of iron-sulfur cluster biogenesis and triggering a complex neurological phenotype of neurodegeneration in early childhood. PMID- 29576219 TI - Bi-allelic Mutations in the Mitochondrial Ribosomal Protein MRPS2 Cause Sensorineural Hearing Loss, Hypoglycemia, and Multiple OXPHOS Complex Deficiencies. AB - Biogenesis of the mitochondrial oxidative phosphorylation system, which produces the bulk of ATP for almost all eukaryotic cells, depends on the translation of 13 mtDNA-encoded polypeptides by mitochondria-specific ribosomes in the mitochondrial matrix. These mitoribosomes are dual-origin ribonucleoprotein complexes, which contain mtDNA-encoded rRNAs and tRNAs and ~80 nucleus-encoded proteins. An increasing number of gene mutations that impair mitoribosomal function and result in multiple OXPHOS deficiencies are being linked to human mitochondrial diseases. Using exome sequencing in two unrelated subjects presenting with sensorineural hearing impairment, mild developmental delay, hypoglycemia, and a combined OXPHOS deficiency, we identified mutations in the gene encoding the mitochondrial ribosomal protein S2, which has not previously been implicated in disease. Characterization of subjects' fibroblasts revealed a decrease in the steady-state amounts of mutant MRPS2, and this decrease was shown by complexome profiling to prevent the assembly of the small mitoribosomal subunit. In turn, mitochondrial translation was inhibited, resulting in a combined OXPHOS deficiency detectable in subjects' muscle and liver biopsies as well as in cultured skin fibroblasts. Reintroduction of wild-type MRPS2 restored mitochondrial translation and OXPHOS assembly. The combination of lactic acidemia, hypoglycemia, and sensorineural hearing loss, especially in the presence of a combined OXPHOS deficiency, should raise suspicion for a ribosomal subunit-related mitochondrial defect, and clinical recognition could allow for a targeted diagnostic approach. The identification of MRPS2 as an additional gene related to mitochondrial disease further expands the genetic and phenotypic spectra of OXPHOS deficiencies caused by impaired mitochondrial translation. PMID- 29576220 TI - Fusion of Three-Dimensional Echocardiographic Regional Myocardial Strain with Cardiac Computed Tomography for Noninvasive Evaluation of the Hemodynamic Impact of Coronary Stenosis in Patients with Chest Pain. AB - BACKGROUND: Combined evaluation of coronary stenosis and the extent of ischemia is essential in patients with chest pain. Intermediate-grade stenosis on computed tomographic coronary angiography (CTCA) frequently triggers downstream nuclear stress testing. Alternative approaches without stress and/or radiation may have important implications. Myocardial strain measured from echocardiographic images can be used to detect subclinical dysfunction. The authors recently tested the feasibility of fusion of three-dimensional (3D) echocardiography-derived regional resting longitudinal strain with coronary arteries from CTCA to determine the hemodynamic significance of stenosis. The aim of the present study was to validate this approach against accepted reference techniques. METHODS: Seventy eight patients with chest pain referred for CTCA who also underwent 3D echocardiography and regadenoson stress computed tomography were prospectively studied. Left ventricular longitudinal strain data (TomTec) were used to generate fused 3D displays and detect resting strain abnormalities (RSAs) in each coronary territory. Computed tomographic coronary angiographic images were interpreted for the presence and severity of stenosis. Fused 3D displays of subendocardial x-ray attenuation were created to detect stress perfusion defects (SPDs). In patients with stenosis >25% in at least one artery, fractional flow reserve was quantified (HeartFlow). RSA as a marker of significant stenosis was validated against two different combined references: stenosis >50% on CTCA and SPDs seen in the same territory (reference standard A) and fractional flow reserve < 0.80 and SPDs in the same territory (reference standard B). RESULTS: Of the 99 arteries with no stenosis >50% and no SPDs, considered as normal, 19 (19%) had RSAs. Conversely, with stenosis >50% and SPDs, RSAs were considerably more frequent (17 of 24 [71%]). The sensitivity, specificity, and accuracy of RSA were 0.71, 0.81, and 0.79, respectively, against reference standard A and 0.83, 0.81, and 0.82 against reference standard B. CONCLUSIONS: Fusion of CTCA and 3D echocardiography-derived resting myocardial strain provides combined displays, which may be useful in determination of the hemodynamic or functional impact of coronary abnormalities, without additional ionizing radiation or stress testing. PMID- 29576221 TI - [Desmoplastic small round cell tumor in children, adolescents and young adults]. AB - Desmoplastic small round cell tumor (DSRCT) is a rare sarcoma that typically affects pediatric and young adult patients with a median age in the general and in the pediatric population of 24.6 years (range 4-58 years) and 15.0 years (range 0-21 years) respectively, with a strong male predominance. This tumor is characterized by a specific t(11;22)(p13;q12) that results in fusion of EWS and WT1 genes which can be demonstrated by RT-PCR or by FISH. DSRCT most frequently presents as an intra-abdominal primary mass associated with peritoneal seeding and a highly aggressive pattern of spread. Generally, all tumors showed the typical histologic findings of variably sized clusters of poly-phenotypic small, round, or spindled cells lying in a desmoplastic stroma. Treatment of this malignancy remains a challenge. The combination of polychemotherapy regimens and aggressive surgery followed by whole abdomen radiation therapy represents nowadays a classical protocol for DSRCT. The survival rate of DSRCT patients is still disappointing around 20 %. However, the survival of patients who had complete resection of the tumor appears better. Hopes are turning to targeted therapeutics against this simple genomic sarcoma. Authors summarize medical knowledge of this rare tumor. PMID- 29576222 TI - Blocking Tim-3 or/and PD-1 reverses dysfunction of tumor-infiltrating lymphocytes in HBV-related hepatocellular carcinoma. AB - BACKGROUND: The immunosuppression of tumor-infiltrating lymphocytes (TILs) is associated with rapid progression of hepatitis B virus-related hepatocellular carcinoma (HBV-HCC). T cell Ig- and mucin-domain-containing molecule-3 (Tim-3) and programmed cell death 1 (PD-1) are important inhibitory molecules expressed on the surface of T cells, but their roles in the function of TILs in HBV-HCC are poorly understood. We aimed to study the roles of these two markers in HBV-HCC. METHODS: Ninety patients with pathologically confirmed HBV-associated HCC were enrolled in our study. Blood samples, paired fresh tumor tissues and adjacent tissues were collected, and isolating peripheral blood mononuclear cells, TILs and adjacent-infiltrating lymphocytes were isolated from these samples. The patients were followed-up to allow survival analysis. RESULTS: Tim-3 or/and PD-1 was up-regulated expressed on CD4+ and CD8+ TILs in HBV-HCC patients and a higher proportion of TILs expressed PD-1 alone. Tim-3+ and PD-1+ TILs greatly decreased secretion of IFN-? and TNF-a. Expression of Tim-3 and PD-1 on TILs negatively correlated with disease-free survival of HCC patients. Direct blockade of Tim-3 and PD-1 in vitro significantly enhanced TILs proliferation and secretion of IFN ? and TNF-a. CONCLUSION: Expression of Tim-3 and/or PD-1 on TILs impairs their function and correlates negatively with disease-free survival in HBV-HCC. Direct blockade of Tim-3 and PD-1 restores anti-tumor effects of TILs, which suggests a potential target for novel immunotherapy in HBV-HCC. PMID- 29576223 TI - Gadolinium-based relative contrast enhancement in primary sclerosing cholangitis: additional benefit for clinicians? AB - AIM: To evaluate the benefit of extracellular gadolinium-based contrast agent (GBCA) enhanced magnetic resonance imaging (MRI) in addition to conventional non enhanced T2-weighted imaging (WI) for quantification of inflammatory or fibrotic alterations in the liver parenchyma of patients with primary sclerosing cholangitis (PSC). MATERIAL AND METHODS: MRI (3 T) examinations were reviewed retrospectively by two radiologists in 27 PSC patients (age 42.9+/-15.6 years), and 19 controls. Regions of interest (ROIs) were drawn onto T2 hyperintense and T2 isointense areas and copied to section position matched non-enhanced and delayed-phase contrast-enhanced T1WI. Signal intensities (SI) obtained from ROIs of the multiphase T1WI were used to calculate relative liver enhancement (RLE). The interobserver agreement of RLE and quantified T2 signal was calculated using Bland-Altman analysis. RLE assessed for both T2 hyperintense (RLEhyper) and T2 isointense (RLEiso) areas were compared in patients and controls (RLEhealthy). RESULTS: The interobserver agreement of RLE in affected hyperintense areas (bias 0.77, limits of agreement -51.7 to 50.1) was superior to the quantification of T2 signal only in these areas (bias -3.35, limits of agreement -162.4 to 155.7). The RLEhyper (86.2+/-9.7%) was higher than the RLEiso (59.8+/-6.2%, p=0.03) and the RLEhealthy (53.2+/-2.7%, p=0.002). The mean RLEiso was not significantly different from the RLEhealthy (p=0.3). CONCLUSION: The extracellular gadolinium based RLE of T2 hyperintense areas could be a useful add-on for routine follow up MRI in the detection of early inflammatory changes, possibly preceding formation of fibrotic scarring in PSC patients, if validated in larger cohorts.

AB - AIM: To compare standard (SD-) and reduced-dose computed tomography (RD-CT) in combination with iterative reconstruction (IR) in emergency patients with suspected lumbar spine fracture. MATERIAL AND METHODS: Forty emergency patients with suspected lumbar spinal disorder who underwent RD-CT and 40 body mass index matched patients undergoing SD-CT were enrolled in this retrospective study. Raw data for RD-CT were reconstructed using two increasing IR levels (IRL) 4 and 6, while SD-CT was reconstructed with IRL3. Two radiologists assessed image quality, image noise, and reader confidence in interpreting findings of spinal fractures in a blinded manner. RESULTS: Effective radiation dose was reduced by 50% using RD-CT. Overall subjective image quality (SIQ) was high for both protocols and slightly superior in the RD-CT protocol for both IRL compared to SD-CT. The detection rate of spinal disorders was high for both protocols with a high interobserver agreement. CONCLUSION: RD-CT with higher levels of IR results in substantial dose reduction of 50% in lumbar spine CT while maintaining an excellent subjective image quality resulting in a high diagnostic confidence.

Selective lobar blockade has been described in patients that do not tolerate one-lung ventilation, and is usually achieved using endobronchial blockers. However, it depends on endobronchial blocker availability, its complexity regarding proper positioning, and the need for constant monitoring to ensure the correct placement of the bronchial seal. In the clinical case to be described, a new method was used to increase the available surface for oxygen exchange. This was accomplished by means of direct supply of oxygen through the bronchoscope's working channel to one of the not-to-be operated-on, non ventilated lung lobes. With this technique, the surgeon had an optimal operating field, oxygenation from one-lung ventilation improved and no perioperative complications were found.

AB - OBJECTIVES: To examine the effects of early comprehensive interventions on home environment and child neurodevelopment among children younger than 3 years in poor rural areas of China, as well as the underlying mediating and moderating mechanisms. STUDY DESIGN: Non-randomized intervention study was conducted among 216 children aged 0-3 years in Shanxi province of China. Based on a 2 * 2 factor design, children in Lin and Fenxi County were assigned to an intervention group with duration less than 1 year (n = 26) or an intervention group with duration longer than 1 year (n = 82), while children in Fangshan County served as a control group with duration less than 1 year (n = 30) or a control group with duration longer than 1 year (n = 78). METHODS: The control group received national public health services (NPHS), while the intervention group received NPHS plus comprehensive interventions covering health, nutrition, early psychosocial stimulation, and child protection. Home environment (Infant-Toddler Home Observation for Measurement of the Environment [HOME]) and child neurodevelopment (Ages and Stages Questionnaire [ASQ]) were measured by observation and interview with mothers after the intervention program. RESULTS: The intervention group showed significantly higher overall HOME, organization, learning materials, and involvement than the control group, only for a duration longer than 1 year. Children in the intervention group performed better in overall ASQ, fine motor, problem-solving, and personal-social than children in the control group. Moderated mediation analyses indicated that there were significantly indirect effects of treatment on overall ASQ through overall HOME, organization, and involvement only when the duration was longer than 1 year. CONCLUSIONS: Early comprehensive interventions longer than 1 year improve home environment and promote child neurodevelopment among children younger than 3 years in poor rural areas. What is more, effects of early comprehensive interventions longer than 1 year on child neurodevelopment were mediated by home environment. PMID- 29576228 TI - Reason for immigration and immigrants' health. AB - OBJECTIVES: The existing literature on the health trajectories of the UK immigrants has mainly focussed on the relationship between ethnicity and health. There is little information on the role of immigration status and no previous information on the role of reason for immigration to the country. This study fills this gap in the literature by analysing the heterogeneity of immigrant native differences in health by reason for immigration. STUDY DESIGN: Analysis of cross-sectional quarterly data from the UK Labour Force Survey covering the period of 2010 (quarter 1) to 2017 (quarter 2). The sample includes 345,086 observations. The dependent variables of interest include suffering from a long lasting condition, the link between long-lasting conditions and labour market performance and the prevalence of 12 specific health conditions. METHODS: Data were analysed using linear probability models to adjust for differences in age, education, gender, ethnicity, local authority of residence and year of survey. The analysis also explores the role of length of stay in the UK and the percentage of current lifetime spent in the UK (duration in the UK/age). RESULTS: Results indicate that, in general, immigrants are less likely than natives to report suffering from a long-lasting (1 year or more) health problem. This pattern generally remains the same when we consider the specificity of the long lasting health problem. However, there are key differences across the immigrant groups by reason for immigration. Those who migrated for employment, family and study reasons report better health outcomes than natives, while those who migrated to seek asylum report worse health outcomes than natives. There is convergence to natives' health outcomes over time for those who migrated for non asylum reasons, but not for those who migrated to seek asylum. CONCLUSIONS: The findings show that the prevalence of health problems differs not only between natives and immigrants but also across groups of immigrants who moved to the UK for different reasons. PMID- 29576229 TI - Are Post-Acute Patients with Behavioral Health Disorders Admitted to Lower Quality Nursing Homes? AB - OBJECTIVES: We measured the proportion of new post-acute nursing home admissions with behavioral health diagnoses and examined whether patients with these disorders (schizophrenia/psychosis, bipolar, depression/anxiety, personality disorder, and substance abuse) faced disparities in access to high quality facilities. SETTING/PARTICIPANTS: The analytical sample included 3,729,282 admissions to 15,600 facilities nationwide for 2012-2014. MEASUREMENT: Quality was measured for overall and staffing domains reported by the Centers for Medicare and Medicaid Services in the Five-Star Quality Rating System. Multinomial logistic regression models were used. The base model included the diagnostic groups of interest and state dummies. Patient sociodemographics, functional and cognitive status, and comorbid conditions were sequentially added to the base model to determine the independent effect of having a behavioral health diagnosis at admission. RESULTS: Patients with these conditions experienced disparities accessing to high-quality homes compared to patients without. For example, patients with depression/anxiety had lower access to five star homes, for the staffing quality domain (Model 3 ORs = 0.88, 0.93, 0.92 in years 1 through 3, respectively) compared to patients with no behavioral health diagnosis. Access disparities were faced not only by patients with serious mental illness, as previously demonstrated, but also patients with substance abuse and with depression/anxiety who account for one-third of all new admissions. CONCLUSIONS: Our findings demonstrate persistence of disparities in access to high quality facilities over time and for patients with a broad range of behavioral health conditions. Further research is needed to understand the impact of these disparities on outcomes of patients with behavioral disorders. PMID- 29576230 TI - Is the 8th edition of the Union for International Cancer Control staging of oral cancer good enough? AB - Depth of invasion is an important predictor of survival. A study by the International Consortium (ICOR) for Outcome Research proposed incorporation of it (together with the greatest surface dimension, or the anatomical criteria, or both) into the T stage. This has been adopted in part by the 8th edition of the Union for International Cancer Control (UICC) TNM 8 classification of malignant tumours for oral squamous cell carcinoma (SCC). Our aim was to verify depth of invasion as an independent prognostic factor, and to validate the staging by comparing it with that specified in the 7th edition (TNM 7) and the T-staging model proposed by the International Consortium. We retrospectively studied 449 patients who had had operations for a previously untreated primary oral cancer between 2006 and 2014 at a single centre, and analysed the independent predictive value of depth of invasion for both disease-specific and overall survival. It was an independent predictor of disease-specific survival as were sex, perineural invasion, and N stage. It was also an independent predictor of overall survival together with sex and N status. Staging in TNM 8 gave a better balance of distribution than that in TNM 7, but did not discriminate between prognosis in patients with T3 and T4 disease. The proposed International Consortium rules for T-staging gave an improved balance in distribution and hazard discrimination. The incorporation of depth of invasion into the T-staging rules for oral SCC improved prognostic accuracy and is likely to influence the selection of patients for adjuvant treatment. Our findings suggest that the TNM 8 staging lacks hazard discrimination in patients with locally-advanced disease because its T4 staging is restricted to anatomical criteria. PMID- 29576231 TI - Incidence of Heart Failure Observed in Emergency Departments, Ambulatory Clinics, and Hospitals. AB - Reports on the burden of heart failure (HF) have largely omitted HF diagnosed in outpatient settings. We quantified annual incidence rates ([IR] per 1,000 person years) of HF identified in ambulatory clinics, emergency departments (EDs), and during hospital stays in a national probability sample of Medicare beneficiaries from 2008 to 2014, by age and race/ethnicity. A 20% random sample of Medicare beneficiaries ages >=65 years with continuous Medicare Parts A, B, and D coverage was used to estimate annual IRs of HF identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Of the 681,487 beneficiaries with incident HF from 2008 to 2014, 283,451 (41%) presented in ambulatory clinics, 76,919 (11%) in EDs, and 321,117 (47%) in hospitals. Overall, incidence of HF in ambulatory clinics decreased from 2008 (IR 22.2, 95% confidence interval [CI] 22.0, 22.4) to 2014 (IR 15.0, 95% CI 14.8, 15.1). Similarly, incidence of HF-related ED visits without an admission to the hospital decreased somewhat from 2008 (IR 5.5, 95% CI 5.4, 5.6) to 2012 (IR 4.2, 95% CI 4.1, 4.3) and stabilized from 2013 to 2014. Similar to previous reports, HF hospitalizations, both International Classification of Diseases, Ninth Revision, Clinical Modification code 428.x in the primary and any position, decreased over the study period. More than half of all new cases of HF in Medicare beneficiaries presented in an ambulatory clinic or ED. The overall incidence of HF decreased from 2008 to 2014, regardless of health-care setting. In conclusion, consideration of outpatient HF is warranted to better understand the burden of HF and its temporal trends. PMID- 29576232 TI - Controversies and Challenges of Ventricular Assist Device Therapy. AB - Left ventricular assist device (LVAD) therapy has emerged as an increasingly vital facet of the treatment algorithm for advanced heart failure. Growing experience with LVAD support has led to substantial improvements in outcomes, with 1-year survival rates approaching that of cardiac transplantation. These therapeutic refinements have engendered growing interests in the potential for expanding the clinical indications for LVAD therapy to patients with less advanced heart failure. The primary obstacles to this evolution of care center largely on the prevention and/or management of the adverse events associated with LVAD therapy along with patient preference. Many programs also face the mounting difficulty of balancing quality outcomes with the increased volume of implants. During the recently assembled Users Meeting organized by St. Jude Medical, heart failure clinicians from nearly 50 LVAD implanting centers discussed these and other challenges and controversies impacting the field. The present review summarizes the key insights gleaned from this meeting. PMID- 29576233 TI - Cardiac Ventricular Contractile Responses to Chronically Increased Afterload Secondary to Right Ventricular Outflow Obstruction in Patients With Tetralogy of Fallot. AB - We examined the adaptive mechanism of the pulmonary ventricle (PV) in response to increased afterload secondary to pulmonary stenosis in tetralogy of Fallot (TOF, n = 47) and congenitally corrected transposition of the great arteries (cCTGA, n = 18), where the PV is morphologically different. We also elucidated the effects of such adaptation on systemic ventricular (SV) function. PV contractility, assessed by dp/dtmax, showed significant positive correlations with PV pressure (r = 0.82, p <0.01 for TOF and r = 0.78, p <0.01 for cCTGA) and pulmonary-to systemic ventricular pressure ratio (r = 0.70, p <0.01 for TOF and r = 0.76, p <0.01 for cCTGA) in patients with both TOF and cCTGA. Notably, the slopes of these correlations were significantly higher in cCTGA than in TOF (p <0.01), suggesting enhanced contractile responses in cCTGA. Moreover, SV dp/dtmax showed significant positive correlations with PV dp/dtmax in patients with both TOF and cCTGA (r = 0.67, p <0.01 and r = 0.61, p <0.01, respectively), indicating positive ventricular-ventricular interaction. In this relationship, the slopes of correlations were significantly higher in TOF than in cCTGA (p = 0.024). These results, indicating different behaviors of PV contractile physiology and its interaction with the SV, may have important therapeutic implications when considering medical, catheter, and surgical interventions for pulmonary stenosis in these diseases. The results may also offer the potential for a new approach for improvement of prognosis, especially in cCTGA. PMID- 29576234 TI - Usefulness of Statins for Prevention of Venous Thromboembolism. AB - Venous thromboembolism (VTE), including deep venous thrombosis and pulmonary embolism, is common with an annual incidence of 1 to 5 per 1,000, resulting in major morbidity, mortality, and increased health care costs. It is more common in the elderly, obese, those with cancer, those undergoing surgery, and those with previous VTE. Strategy to reduce its occurrence has important public health implications. Pleotropic effects of statins may have beneficial effects on a number of potential targets associated with VTE. Statins have excellent safety profile and seem to be associated with beneficial effects in VTE in case-control studies, large observational studies, meta-analyses, and a randomized trial. In conclusion, after critically reviewing the clinical data supporting statin use in the prevention of VTE, we presented clinical recommendations for the use of statins in reducing VTE occurrence, especially in high-risk situations. PMID- 29576235 TI - Meta-Analysis Comparing Neurohumoral Antagonist Use in Patients >=75 Years Versus <75 Years Receiving Cardiac Resynchronization Therapy. AB - Neurohumoral antagonists are the foundation of heart failure therapy in patients with reduced left ventricular ejection fraction. Cardiac resynchronization therapy (CRT) has also been associated with improved outcomes in these patients. We aimed to evaluate the use of neurohumoral antagonists in patients >=75 years compared with <75 years of age receiving CRT. We searched electronic databases, up to December 20, 2016 for all studies reporting medication use in patients >=75 years and <75 years of age who received CRT. We used random-effects meta-analysis models to summarize the studies. We retained 12 studies (1 randomized trial and 11 observational studies) enrolling 5,728 >=75 years old and 9,549 patients of <75 years old. There were lower use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers in patients >=75 years compared with patients <75 years (odds ratio [OR] 0.59, 95% confidence interval [CI] 0.47 to 0.74, p < 0.0001). In addition, there were lower use of mineralocorticoid receptor antagonists in patients >=75 years compared with patients <75 years (OR 0.48, 95% CI 0.40 to 0.57, p < 0.0001). The use of beta blockers was nonsignificantly lower in patients >=75 years compared with patients <75 years (OR 0.70, 95% CI 0.47 to 1.03, p = 0.07). In conclusion, neurohumoral antagonists appeared to be underused in patients >=75 years compared with patients <75 years receiving CRT. Consideration should be given to increase neurohumoral antagonism in patients >=75 years referred for CRT. PMID- 29576237 TI - Errata. PMID- 29576236 TI - Relation of Resting Heart Rate to Incident Atrial Fibrillation (From ARIC [Atherosclerosis Risk in Communities] Study). AB - The evidence on the association between resting heart rate (HR) and incident atrial fibrillation (AF) is conflicting. Whether change in resting HR is associated with incident AF is unknown. We evaluated 11,545 participants (mean [+/-standard deviation] age: 57 +/- 5.7 years) free of AF at baseline (1990 to 1992). Resting HR was obtained from 10-second electrocardiograms at baseline and 3 years later. AF diagnosis was ascertained from visit electrocardiograms, hospital discharge records, and death certificates through 2013. High and low resting HR were defined as >=80 and <55 beats/min, respectively. Increase and decrease in HR were defined as a 3-year HR difference >15 and <-15 beats/min, respectively. Over a median follow-up of 22.5 years, 1,746 (15%) participants developed AF. Both baseline high resting HR and increase in HR were independently associated with incident AF (hazard ratio = 1.2, 95% confidence interval = 1.0 to 1.5 and hazard ratio = 1.4, 95% confidence interval = 1.1 to 1.9). Increase in HR was no longer associated with incident AF after additional adjustment for incident heart failure. In stratified analyses, increase in HR was associated only with AF in participants <60 years, with bachelor's degree or above, without diabetes, and without hypertension (p values for interaction <=0.05). In conclusion, in a middle-aged population, high resting HR is associated with higher AF risk. Increase in resting HR is also associated with higher AF risk, especially in individuals without traditional AF risk factors. Whether interventions to decrease HR can prevent AF remain to be examined. PMID- 29576238 TI - Erratum. PMID- 29576239 TI - Epidemiology and outcomes of traumatic knee dislocations: Isolated vs multi trauma injuries. AB - BACKGROUND AND PURPOSE: Traumatic dislocation of the knee (TKD) is a rare injury, accounting for approximately 0.02% of orthopaedic injuries. They are a challenging entity for orthopaedic surgeons to manage, and can have devastating consequences. The aim of this study was to describe the epidemiology of traumatic knee dislocations (TKD'S) and contrast the incidence of neurovascular injury between isolated and multi-trauma dislocations as well as key patient reported outcomes achieved between these groups. MATERIAL AND METHODS: Patients who had a traumatic disruption of the tibiofemoral articulation between March 1 2007 and February 31, 2015 were identified from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Data was cross-checked with medical records and radiological reports to confirm true multi-ligamentous dislocation. VOTOR collects information pertaining to orthopaedic injuries, treatment, complications and outcomes from four adult hospitals in Victoria, Australia, including the major trauma centers. Patient-reported outcomes are collected by VOTOR at 12 months post-injury including the EQ-5D-3L (EQ-5D) and Glasgow Extended Outcome Scores (GOS-E) and return to work status. Patient reported functional and quality of life outcomes at 12 months after injury were analysed. RESULTS: A cohort of 88 patients were identified that fit the inclusion criteria for the study, and at 12 months post injury there was data available for 80 patients (90.9%). There were 38 (42.9%) patients who experienced an isolated traumatic knee dislocation and 52 (57.1%) who experienced a traumatic knee dislocation in association with another injury. Of the 88 patients identified as eligible for the study, two had bilateral knee dislocations, hence there were 90 multi-ligamentous knee injuries. Those who were injured at a higher velocity were more likely to have additional injuries. Dislocations that occurred at a lower velocity were shown to have better overall outcomes, as did dislocations that occurred in isolation. CONCLUSIONS: Traumatic knee dislocations that occur in isolation typically result in better outcomes than those that occur with associated injuries. TKD's are a rare but severe injury that requires further research in order for functional outcomes to be optimized. PMID- 29576240 TI - Question 1: Why do children still die from asthma? AB - Asthma is one of the commonest chronic conditions in children and can occasionally be fatal. Little has changed regarding the risk factors for children dying from asthma in the last 30 years. The majority of deaths from asthma occur in children from socio-economically disadvantaged backgrounds. These should be preventable with better education of families, oversight of medication adherence and improved communication between health care professionals and families. More needs to be done to deliver basic messages more effectively about asthma management to the most vulnerable in communities around the world. PMID- 29576241 TI - Synthesis, characterization and DNA interactions of [Pt3(TPymT)Cl3], the trinuclear platinum(II) complex of the TPymT ligand. AB - The triplatinum complex of the 2,4,6-Tris(2-pyrimidyl)-1,3,5-triazine ligand, Pt3TPymT hereafter, has been prepared and characterized for the first time. NMR studies point out that the three platinum(II) centers possess an identical coordination environment. The interactions of Pt3TPymT with DNA were explored in comparison to the free ligand. Specifically, fluorescence, mass spectrometry, viscometry and melting measurements were carried out. In contrast to expectations, the obtained data reveal that no intercalative binding takes place; we propose that binding of Pt3TPymT to DNA mainly occurs through external/groove binding.

PMID- 29576242 TI - Interactions of iron-bound frataxin with ISCU and ferredoxin on the cysteine desulfurase complex leading to Fe-S cluster assembly. AB - Frataxin (FXN) is involved in mitochondrial iron-sulfur (Fe-S) cluster biogenesis and serves to accelerate Fe-S cluster formation. FXN deficiency is associated with Friedreich ataxia, a neurodegenerative disease. We have used a combination of isothermal titration calorimetry and multinuclear NMR spectroscopy to investigate interactions among the components of the biological machine that carries out the assembly of iron-sulfur clusters in human mitochondria. Our results show that FXN tightly binds a single Fe2+ but not Fe3+. While FXN (with or without bound Fe2+) does not bind the scaffold protein ISCU directly, the two proteins interact mutually when each is bound to the cysteine desulfurase complex ([NFS1]2:[ISD11]2:[Acp]2), abbreviated as (NIA)2, where "N" represents the cysteine desulfurase (NFS1), "I" represents the accessory protein (ISD11), and "A" represents acyl carrier protein (Acp). FXN binds (NIA)2 weakly in the absence of ISCU but more strongly in its presence. Fe2+-FXN binds to the (NIA)2-ISCU2 complex without release of iron. However, upon the addition of both l-cysteine and a reductant (either reduced FDX2 or DTT), Fe2+ is released from FXN as consistent with Fe2+-FXN being the proximal source of iron for Fe-S cluster assembly. PMID- 29576244 TI - Exploring the training and scope of practice of GPs in England, Germany and Spain. AB - OBJECTIVE: To explore general practitioner (GP) training, continuing professional development, scope of practice, ethical issues and challenges in the working environment in three European countries. METHOD: Qualitative study of 35 GPs from England, Germany and Spain working in urban primary care practices. Participants were recruited using convenience and snowball sampling techniques. Semi structured interviews were recorded, transcribed and analysed by four independent researchers adopting a thematic approach. RESULTS: Entrance to and length of GP training differ between the three countries, while continuing professional development is required in all three, although with different characteristics. Key variations in the scope of practice include whether there is a gatekeeping role, whether GPs work in multidisciplinary teams or singlehandedly, the existence of appraisal processes, and the balance between administrative and clinical tasks. However, similar challenges, including the need to adapt to an ageing population, end-of-life care, ethical dilemmas, the impact of austerity measures, limited time for patients and gaps in coordination between primary and secondary care are experienced by GPs in all three countries. CONCLUSION: Primary health care variations have strong historical roots, derived from the different national experiences and the range of clinical services delivered by GPs. There is a need for an accessible source of information for GPs themselves and those responsible for safety and quality standards of the healthcare workforce. This paper maps out the current situation before Brexit is being implemented in the UK which could see many of the current EU arrangements and legislation to assure professional mobility between the UK and the rest of Europe dismantled.

PMID- 29576246 TI - Autoantibodies targeting TLR and SMAD pathways define new subgroups in systemic lupus erythematosus. AB - OBJECTIVES: The molecular targets of the vast majority of autoantibodies in systemic lupus erythematosus (SLE) are unknown. We set out to identify novel autoantibodies in SLE to improve diagnosis and identify subgroups of SLE individuals. METHODS: A baculovirus-insect cell expression system was used to create an advanced protein microarray with 1543 full-length human proteins expressed with a biotin carboxyl carrier protein (BCCP) folding tag, to enrich for correctly folded proteins. Sera from a discovery cohort of UK and US SLE individuals (n = 186) and age/ethnicity matched controls (n = 188) were assayed using the microarray to identify novel autoantibodies. Autoantibodies were validated in a second validation cohort (91 SLE, 92 controls) and a confounding rheumatic disease cohort (n = 92). RESULTS: We confirmed 68 novel proteins as autoantigens in SLE and 11 previous autoantigens in both cohorts (FDR<0.05). Using hierarchical clustering and principal component analysis, we observed four subgroups of SLE individuals associated with four corresponding clusters of functionally linked autoantigens. Two clusters of novel autoantigens revealed distinctive networks of interacting proteins: SMAD2, SMAD5 and proteins linked to TGF-beta signalling; and MyD88 and proteins involved in TLR signalling, apoptosis, NF-kappaB regulation and lymphocyte development. The autoantibody clusters were associated with different patterns of organ involvement (arthritis, pulmonary, renal and neurological). A panel of 26 autoantibodies, which accounted for four SLE clusters, showed improved diagnostic accuracy compared to conventional antinuclear antibody and anti-dsDNA antibody assays. CONCLUSIONS: These data suggest that the novel SLE autoantibody clusters may be of prognostic utility for predicting organ involvement in SLE patients and for stratifying SLE patients for specific therapies. PMID- 29576248 TI - Ultrasound-Guided Percutaneous Core Needle Biopsy for the Diagnosis of Pancreatic Disease. AB - Few studies have evaluated the performance of percutaneous core needle biopsies of the pancreas. This article is an overview of the advantages, disadvantages, predictive power and complications associated with percutaneous ultrasound-guided core needle biopsies of pancreatic lesions. A comprehensive literature search of Medline (using PubMed as the search engine) and EMBASE was done to identify suitable studies up to March 2017. A study of quantitative pre-operative pancreatic biopsy data was reported. Lesion location, mean or median number of passes, inadequate tissue or technical failures and complications were assessed for all cases by reviewing clinical notes and post-procedural imaging. The analysis included 13 studies, mostly of a retrospective nature. The sensitivity (mean: 94.42%, range: 90%-100%) and specificity (mean: 97.94%, range: 94.7%-100%) of the procedure were high, and the mean accuracy of diagnosis was 95.76 (range: 91-100). Furthermore, the procedure had a high negative predictive value of approximately 76.26%. Of the 13 reported studies, 7.3% were inadequate or technical failure cases. The mean rate of complications was 2.08%, which seemed similar to the lower limit of this rate for endoscopic ultrasound-guided fine needle aspirations. The risk of tumor seeding with ultrasound-guided core needle biopsies was not reported in the included articles. With the development of technology, ultrasound-guided percutaneous core needle biopsy for pancreatic lesions is increasingly available and has optimal diagnostic power in pancreatic neoplasms. PMID- 29576247 TI - "Tweet"-Format Writing Is an Effective Tool for Medical Student Reflection. AB - OBJECTIVE: Reflective writing during medical education allows for professional growth through retrospective analysis of experiential knowledge. However, these writing assignments can pose a challenge to millennial medical students who are more likely to assimilate knowledge through the use of innovative technology and who prefer their data in a concise format. Here, we present a novel, tweet-style reflective writing assignment to better engage the unique skill set of today's medical students. We analyzed the written content partway through the year to determine whether or not the format retains the impact of longer, more structured reflective writing assignments. DESIGN: Surgical clerkship students were required to reflect on 3 distinct experiences through a 140-character written reflection, or tweet. Students were able to submit these assignments at any point during their rotation through a platform available on their smartphone or computer. There were no specifications with regard to content. These reflections were analyzed using modified grounded theory methods. Each tweet was analyzed by 2 individuals to ensure intercoder reliability. Codes were created a priori with respect to positive and negative domains, and type of experience. STETTING: Department of Surgery, Warren Alpert School of Medicine, Brown University, Third Year Medical Student Surgical Clerkship. PARTICIPANTS: Third year medical students at the Warren Alpert School of Medicine, Brown University. Fifty-six medical students were included in this study. RESULTS: During the first 4 blocks of the 2016-2017 academic year, 56 students rotated through the third year surgical clerkship. One hundred and sixty-eight tweets were collected and coded. Sixty-nine tweets (42%) had a positive valence. Students reflected on the following experiences: patient interaction (54%), surgical education (34%), physician/resident interaction (27%), and career decisions (11%). Overall, 87 (52%) tweets were reflective. Many tweets included emotional reactions to specific experiences. CONCLUSIONS: Using tweet-style reflective writing, students identified and reacted to multiple salient experiences from their surgical clerkship. They reflected on both positive and negative emotions, mostly related to personal interactions with patients, but also associated with their education, their team, and their future career. Based on early analysis of the data, we believe that short format writing can be an effective format for reflection.

PMID- 29576250 TI - Dietary inflammatory index or Mediterranean diet score as risk factors for total and cardiovascular mortality. AB - BACKGROUND AND AIMS: Dietary patterns are associated with risk of cardiovascular disease (CVD). We aimed to examine associations of the Dietary Inflammatory Index (DII) and the Mediterranean Diet Score (MDS) with total, cardiovascular disease (CVD) and coronary heart disease (CHD) mortality in the Melbourne Collaborative Cohort Study; and compare the strengths of the associations. METHODS AND RESULTS: In our prospective cohort study of 41,513 men and women aged 40-69 years, a food frequency questionnaire was completed at baseline and mortality data were obtained via linkage with local and national registries over an average of 19 years follow up. At baseline, questionnaires were completed and physical measures and blood samples taken. Cox proportional hazards models, adjusting for age, alcohol consumption, sex, region of origin, personal history of CVD or diabetes and family history of CVD, were used to assess associations between dietary scores and mortality. More Mediterranean or less inflammatory diets were associated with lower total, CVD and CHD mortality. The hazard ratio for total mortality comparing the highest and lowest quintiles was 1.16 (95%CI: 1.08-1.24) for DII; and 0.86 (95%CI: 0.80-0.93) comparing the highest and lowest three categories of MDS. Using the Bayesian information criterion, there was no evidence that the DII score was more strongly associated with total and CVD mortality than was the MDS. CONCLUSIONS: The MDI and the DII show similar associations with total and cardiovascular mortality, consistent with the consensus that plant-based diets are beneficial for health.

AB - We describe how Photovoice-a participatory method in which people express and share ideas via images-has been used in research with people living with HIV (PLWH). Four databases, reference lists, and journal tables of content were searched to identify peer-reviewed original research, in English, using Photovoice with a sample of PLWH, between 1994 and 2016. Of 1,898 citations identified, 22 studies were included. Studies included a mean of 18 (range 4-38) participants. Studies were of strong quality but lacked consistent procedures. Goals varied and projects included different combinations of introductory, photo training, ethics, group, individual, and exhibit sessions. Descriptions of the researcher-participant relationship were uneven. Photovoice allowed PLWH to inform research and practice priorities through their own visual perspectives. Continued use of Photovoice with PLWH is recommended with greater emphasis on consistent methods and detailed reporting; more studies should be undertaken resulting in actions or advocacy.

Cow's milk allergy (CMA) involves immunoglobulin E (IgE)- and non-IgE mediated reactions, the latter being both variable and nonspecific. Guidelines thus emphasize the need for physicians to recognize the specific syndromes of CMA and to respect strict diagnostic modalities. Whatever the clinical pattern of CMA, the mainstay of treatment is the elimination from the diet of cow's milk proteins. The challenge is that both the disease and the elimination diet may result in insufficient height and weight gain and bone mineralization. If, during CMA, the mother is not able or willing to breastfeed, the child must be fed a formula adapted to CMA dietary management, during infancy and later, if the disease persists. This type of formula must be adequate in terms of allergic efficacy and nutritional safety. In older children, when CMA persists, the use of cow's milk baked or heated at a sufficient temperature, frequently tolerated by children with CMA, may help alleviate the stringency of the elimination diet. Guidance on the implementation of the elimination diet by qualified healthcare professionals is always necessary. This guidance should also include advice to ensure adequate bone growth, especially relating to calcium intake. Specific attention should be given to children presenting with several risk factors for weak bone mineral density, i.e., multiple food allergies, vitamin D deficiency, poor sun exposure, steroid use, or severe eczema. When CMA is outgrown, a prolonged elimination diet may negatively impact the quality of the diet over the long term.

AB - INTRODUCTION: The receptor CD36 has been reported to play an important role in atherogenicity. The aim of this study was to gain insight into the relationship between CD36 gene polymorphisms or the plasma concentration of sCD36 and clinical or biochemical parameters in children. PATIENTS AND METHODS: The study groups comprised Caucasian children with and without hypercholesterolemia. The alterations in the CD36 gene were detected by DHPLC and the plasma concentrations of sCD36 were measured by ELISA. RESULTS: The data presented suggest that the IVS4-10A allele of CD36 (rs3211892) is associated with a lower risk of hypercholesterolemia. We observed a negative correlation of the sCD36 concentration with uric acid and insulin concentrations, the HOMA-IR ratio, weight, waist and hip circumference, systolic blood pressure, body mass index, waist-hip ratio and mean arterial pressure ratio, but a positive correlation with HDL cholesterol and ApoA1 concentrations. Female gender was a significant independent predictor of a higher plasma sCD36 concentration. CONCLUSIONS: The data presented suggest a possible protective effect of a higher sCD36 concentration in relation to metabolic syndrome components.

PMID- 29576257 TI - Mortality outcomes based on ED qSOFA score and HIV status in a developing low income country. AB - OBJECTIVE: To evaluate the utility of the quick Sepsis-related Organ Failure Assessment (qSOFA) score to predict risks for emergency department (ED) and hospital mortality among patients in a sub-Saharan Africa (SSA) setting. METHODS: This retrospective cohort study was carried out at a tertiary-care hospital, in Kigali, Rwanda and included patients >=15years, presenting for ED care during 2013 with an infectious disease (ID). ED and overall hospital mortality were evaluated using multivariable regression, with qSOFA scores as the primary predictor (reference: qSOFA=0), to yield adjusted relative risks (aRR) with 95% confidence intervals (CI). Analyses were performed for the overall population and stratified by HIV status. RESULTS: Among 15,748 cases, 760 met inclusion (HIV infected 197). The most common diagnoses were malaria and intra-abdominal infections. Prevalence of ED and hospital mortality were 12.5% and 25.4% respectively. In the overall population, ED mortality aRR was 4.8 (95% CI 1.9 12.0) for qSOFA scores equal to 1 and 7.8 (95% CI 3.1-19.7) for qSOFA scores >=2. The aRR for hospital mortality in the overall cohort was 2.6 (95% 1.6-4.1) for qSOFA scores equal to 1 and 3.8 (95% 2.4-6.0) for qSOFA scores >=2. For HIV infected cases, although proportional mortality increased with greater qSOFA score, statistically significant risk differences were not identified. CONCLUSION: The qSOFA score provided risk stratification for both ED and hospital mortality outcomes in the setting studied, indicating utility in sepsis care in SSA, however, further prospective study in high-burden HIV populations is needed.

AB - BACKGROUND: The optimal management and prognostic factors of postsurgical pulmonary vein stenosis remain controversial. We sought to determine current postsurgical pulmonary vein stenosis outcomes and prognostic factors in a multicentric study in the current era. METHODS: Seventy-five patients with postsurgical pulmonary vein stenosis who underwent 103 procedures in 14 European/North American centers (2000-2012) were included retrospectively. A specific pulmonary vein stenosis severity score was developed on the basis of the assessment of each pulmonary vein. End points were death, pulmonary vein reintervention, and restenosis. A univariate and multivariate risk analysis was performed. RESULTS: Some 76% of postsurgical pulmonary vein stenosis occurred after repair of a total anomalous pulmonary venous return. Sutureless repair was used in 42 of 103 procedures (41%), patch veinoplasty was used in 28 procedures (27%), and endarterectomy was used in 16 procedures (16%). Overall pulmonary vein restenosis, reintervention, and mortality occurred in 56% (n = 58/103), 49% (n = 50/103), and 27% (n = 20/75), respectively. Sutureless repair was associated with less restenosis (40% vs 67%; P = .007) and less reintervention (31% vs 61%; P = .003). Mortality after sutureless repair (20%; 7/35) tends to be lower than after nonsutureless repair (33%; 13/40) (P = .22). A high postoperative residual pulmonary vein stenosis score at the time of hospital discharge was an independent risk factor for restenosis (hazard ratio [HR], 1.55; P < 10-4), reintervention (HR, 1.33; P < 10-4), and mortality (HR, 1.37; P < 10-4). The sutureless technique was an independent protective factor against restenosis (HR, 0.27; P = .006). CONCLUSIONS: Postsurgical pulmonary vein stenosis still has a guarded prognosis in the current era. The sutureless technique is an independent protective factor against restenosis. The severity of the residual disease evaluated by a new severity score is an independent risk factor for poor outcomes regardless of surgical technique.

PMID- 29576265 TI - Cost-effectiveness of Pembrolizumab in Second-line Advanced Bladder Cancer. AB - BACKGROUND: Immune-modulating drugs have recently been introduced to the second line setting of advanced bladder cancer. Pembrolizumab increases overall survival and is associated with less toxicity compared with chemotherapy in this setting based on the Keynote 045 study. The high cost of immunotherapy necessitates an assessment of its value by considering both efficacy and cost. OBJECTIVE: To estimate the cost-effectiveness of pembrolizumab for the second-line treatment of advanced bladder cancer from the perspective of payers in multiple countries. DESIGN, SETTING, AND PARTICIPANTS: We developed a Markov model to compare the cost and effectiveness of pembrolizumab with those of chemotherapy in the second line treatment of advanced bladder cancer based on the Keynote 045 study. Drug costs were acquired for the United States (US), United Kingdom (UK), Canada, and Australia. All costs were converted from local currency to US dollars at the exchange rates in September 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Health outcomes were measured in quality-adjusted life-years (QALYs). RESULTS AND LIMITATIONS: Pembrolizumab generated a gain of 0.36-0.37 QALYs compared with chemotherapy. Our analysis established the following incremental cost effectiveness ratios (ICERs) for pembrolizumab versus chemotherapy in second-line advanced bladder cancer treatment: US $122 557/QALY; UK $91 995/QALY; Canada $90 099/QALY; and Australia $99 966/QALY. The willingness-to-pay (WTP) thresholds per QALY are considered to be around 100 000-150 000 US dollars for the US, 20 000-50 000 pounds for the UK (US$25 000-65 000), 20 000-100 000 CAD for Canada (US$16 000-80 000), and 40 000-75 000 AUD for Australia (US$32 000-60 000). CONCLUSIONS: Cost-effectiveness and WTP thresholds vary between countries. Compared with the other countries examined, US drug prices were found to be the highest, leading to the highest ICER. With standard WTP thresholds, pembrolizumab may be considered cost-effective in the US but not in the other countries examined. PATIENT SUMMARY: This article assessed the cost-effectiveness of pembrolizumab for the treatment of patients with metastatic bladder cancer who had previously failed one treatment regimen. It would cost $122 557 in the United States, $91 995 in the United Kingdom, $90 099 in Canada, and $99 966 in Australia to gain one quality-adjusted life-year with pembrolizumab versus chemotherapy in these patients, which may be considered cost-effective only in the United States because of the differences in willingness-to-pay thresholds. PMID- 29576266 TI - Exploring lipid markers of the quality of coix seeds with different geographical origins using supercritical fluid chromatography mass spectrometry and chemometrics. AB - BACKGROUND: Lipids, a group of primary metabolites, could be used as quality markers of Traditional Chinese medicine. PURPOSE: The present study was designed to develop a research method to explore lipid markers of the quality of coix seeds with different geographical origins. STUDY DESIGN: The geographical origins of coix seeds were divided into three regions based on the latitude. A central composite design (CCD test) was used to optimize the chromatographic parameters of supercritical fluid chromatography to obtain optimal lipid profile of coix seed. METHODS: An untargeted method based on ultra-performance convergence chromatography - quadrupole/time-of-flight hybrid mass spectrometry (UPC2-QTOF) was developed. Four chromatographic parameters were optimized using CCD test, and a fusion index established by Derringer function was used to evaluate. The lipid profile of 27 batches of coix seeds were acquired and processed by Progenesis QI software, and the MS/MS spectrums were obtained to identify, simultaneously. The difference lipids were explored by orthogonal partial least squares discriminant analysis (OPLS-DA). The lipids that showed differences depending on their seeds' geographical origin were selected as markers of the quality of coix seeds from the three regions. RESULTS: A Torus 2-PIC (1.7 um, 100 mm * 3.0 mm) was selected as the optimal column of the untargeted method which the run time was only 8 minutes. From the CCD test, the interaction of chromatographic parameters between column temperature and backpressure was founded which the optimal parameters were 55 degrees C and 2600 psi, respectively. Thirty-two peaks in the lipid profile of coix seed were tentatively identified, of which 20 were triglyceride, and 12 were diglyceride. Nine features that could potentially be used to distinguish the coix seeds by their geographical origin were identified, most of which were diglycerides, such as OP. CONCLUSIONS: Our findings confirm that UPC2-QTOF combined with chemometrics could be used as an efficient method for exploring potential lipid markers of the quality of herbal medicine. PMID- 29576267 TI - Interaction between the Opioid Receptor OPRM1 Gene and Mother-Child Language Style Matching Prospectively Predicts Children's Separation Anxiety Disorder Symptoms. AB - Recent research suggests that lower mother-child language style matching (LSM) is associated with greater physiological reactivity and insecure attachment in school-aged children, but to date no studies have explored this measure of parent child behavioral matching for its association with children's anxiety symptoms, a well-known correlate of attachment insecurity and heightened physiological reactivity. There is also considerable evidence of genetic risk for anxiety, including possession of the OPRM1 minor allele, 118G. In the current study (N = 44), we expand upon what is known about children's genetic and environmental risk for anxiety by examining the unique and interactive effects of mother-child LSM and the OPRM1 polymorphism A118G on school-aged children's separation anxiety disorder (SAD) symptoms. SAD symptoms were measured both concurrently with LSM and OPRM1 genotype and two years later through self-report. No significant associations emerged between LSM or OPRM1 and concurrent Time 1 SAD symptoms. However, lower LSM and 118G minor allele possession were both associated with greater SAD symptoms at Time 2; further, the interaction between LSM and OPRM1 genotype significantly predicted SAD symptoms beyond the main effects of the two variables. Possession of the minor allele was only associated with greater SAD symptoms among children in low LSM dyads, whereas children with the minor allele in high LSM dyads showed non-significantly lower SAD symptoms. These findings and a proportion affected analysis provide support for a differential susceptibility model of gene by environment interactions for the OPRM1 gene. We discuss the implications for predicting children's separation anxiety across development. PMID- 29576268 TI - Corrections. PMID- 29576269 TI - The risk of prostate cancer mortality and cardiovascular mortality of nonmetastatic prostate cancer patients: A population-based retrospective cohort study. AB - PURPOSE: To assess the risk of prostate cancer (PCa) specific mortality (PCSM) compared to cardiovascular disease mortality (CVDM), or other-cause mortality (OCM) of men with nonmetastatic PCa according to PCa risk groups, primary treatment, and age. PATIENTS AND METHODS: This retrospective population-based cohort study identified 1,908 nonmetastatic PCa patients in the cancer registry Zurich and Zug, diagnosed between 2000 and 2009 living in the City of Zurich. Multiple imputation methods were applied to handle missing PCa information. Fine and Gray competing risk regression analysis was used to estimate subdistribution hazard ratios for the outcomes PCSM, CVDM, or OCM RESULTS: Ten years after diagnosis the cumulative probability of PCSM and CVDM was 16.4% and 10.0%, respectively. We observed an increased adjusted risk of PCSM in men treated with androgen deprivation therapy (ADT) compared to surgery, but could not observe an association between ADT and CVDM. The probability of PCSM was significantly higher for patients on active surveillance or watchful waiting, compared to surgery. Age and PCa risk categories were positively associated with risk of PCSM, whereas there was no evidence for an association with CVDM or OCM based on risk groups. CONCLUSIONS: Overall, men with PCa were more likely to die from non PCa related outcomes. Nevertheless, the analyses showed a high proportion of PCSM among men on ADT, older men and men with a high-risk tumor. However, further research is needed to understand comprehensively the benefits of the respective treatments. PMID- 29576270 TI - Synthesis and biological evaluation of pyrimidine derivatives as novel human Pin1 inhibitors. AB - Pin1 (Protein interacting with NIMA1) is a cis-trans isomerase and promotes the amide bond rotation of phosphoSer/Thr-Pro motifs in its substrates. Inhibition of Pin1 might be a novel strategy for developing anticancer agents. Herein, a series of pyrimidine derivatives were synthesized and their Pin1 inhibitory activities were evaluated. Among them, four compounds (2a, 2f, 2h and 2l) displayed potent inhibitory activities against Pin1 with IC50 values lower than 3 uM. This series of pyrimidine-based inhibitors presented time-dependent inhibition against Pin1. The structure-activity relationships on the 2-, 4- and 5-positions of the pyrimidine ring were analyzed in details, which would facilitate further exploration of new Pin1 inhibitors. PMID- 29576271 TI - 2,4-Diamino-8-quinazoline carboxamides as novel, potent inhibitors of the NAD hydrolyzing enzyme CD38: Exploration of the 2-position structure-activity relationships. AB - Starting from 4-amino-8-quinoline carboxamide lead 1a and scaffold hopping to the chemically more tractable quinazoline, a systematic exploration of the 2 substituents of the quinazoline ring, utilizing structure activity relationships and conformational constraint, resulted in the identification of 39 novel CD38 inhibitors. Eight of these analogs were 10-100-fold more potent human CD38 inhibitors, including the single digit nanomolar inhibitor 1am. Several of these molecules also exhibited improved therapeutic indices relative to hERG activity. A representative analog 1r exhibited suitable pharmacokinetic parameters for in vivo animal studies, including moderate clearance and good oral bioavailability. These inhibitor compounds will aid in the exploration of the enzymatic functions of CD38, as well as furthering the study of the therapeutic implications of NAD enhancement in metabolic disease models. PMID- 29576272 TI - Synthesis and evaluation of 2,9-disubstituted 8-phenylthio/phenylsulfinyl-9H purine as new EGFR inhibitors. AB - In present study, we described the synthesis and biological evaluation of a new class of EGFR inhibitors containing 2,9-disubstituted 8-phenylthio/phenylsulfinyl 9H-purine scaffold. Thirty-one compounds were synthesized. Among them, compound C9 displayed the IC50 of 29.4 nM against HCC827 cell line and 1.9 nM against EGFRL858R. Compound C12 showed moderate inhibitory activity against EGFRL858R/T790M/C797S (IC50 = 114 nM). Western bolt assay suggested that compound C9 significantly inhibited EGFR phosphorylation. In vivo test, compound C9 remarkably exhibited inhibitory effect on tumor growth at 5.0 mg/kg by oral administration in established nude mouse HCC827 xenograft model. These results indicate that the 2,9-disubstituted 8-phenylsulfinyl/phenylsulfinyl-9H-purine derivatives can act as potent EGFR(L858R) inhibitors and effective anticancer agents. Additionally, optimization of compound C12 may result in discovering the fourth-generation EGFR-TKIs. PMID- 29576273 TI - Knowledge translation and the health of people with disability.

PMID- 29576275 TI - Liquid chromatography - high resolution mass spectrometry method for monitoring of 17 mycotoxins in human plasma for exposure studies. AB - Mycotoxins are secondary metabolites produced by filamentous fungi. Primary route of human exposure to mycotoxins is the intake of the contaminated food. Minimizing mycotoxin exposure is important for population health, as their chronic toxic effects have been associated with kidney and liver diseases, some types of cancer and immunosuppression. The objective of this work was to develop and validate a multi-class mycotoxin method suitable for exposure monitoring of mycotoxins in human plasma. A sensitive liquid chromatography - mass spectrometry method was developed for 17 mycotoxins: nivalenol (NIV), deoxynivalenol, fusarenon X, 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol, T-2 toxin, HT-2 toxin, aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, zearalenone, alpha zearalenol (alpha-ZOL), beta-zearalenol, zearalanone, alpha-zeranol and, and beta zeranol. The method relies on three-step liquid-liquid extraction with ethyl acetate to eliminate the need for immunoaffinity extraction and minimize ionization matrix effects. Chromatographic separation of mycotoxins, including all isomers, was achieved with pentafluorophenyl column and water/methanol mobile phase. Mycotoxin detection and quantitation were performed using high-resolution mass spectrometry on LTQ Velos Orbitrap, in both positive and negative electrospray ionization (ESI(+) and (ESI(-)). The use of 0.02% acetic acid as mobile phase additive for ESI(-) resulted in significant increase in ionization efficiency ranging from 1.7 to 26 times for mycotoxins that ionize better in ESI( ). The optimized method was validated according to FDA guidance procedures. LOQs of all mycotoxins ranged from 0.1 to 0.5 ng/ml, except NIV which resulted in LOQ of 3 ng/ml because of low extraction recovery of this highly polar mycotoxin. Mean intra-day accuracy ranged from 85.8% to 116.4%, and intra-day precision (n = 6) ranged from 1.6% to 12.5% RSD for all mycotoxins except alpha-ZOL where mean accuracy ranged from 72.9% to 97.2%. Inter-day accuracy and precision were 85.6% 111.5% and 2.7-15.6% RSD respectively, showing good analytical performance of the method for biomonitoring. PMID- 29576276 TI - Liquid chromatography with alkylammonium formate ionic liquid mobile phases and fluorescence detection. AB - Fluorescence detection of various pharmaceuticals and the amino acid tryptophan (low molecular weight organic compounds) as well as the enzyme lactate dehydrogenase LDH (high molar mass compound) has been studied in aqueous solutions using alkyl ammonium formate ionic liquids as the primary solvent component. It was expected that the high viscosity of such ionic liquid-water mixtures would enhance fluorescence. Pharmaceuticals such as riboflavin and naproxen showed no such enhancement in the presence of ethylammonium formate (EAF) or isopropylammonium formate (IPAF) but the fluorescence of warfarin was substantially enhanced by a factor of 4 with 80% EAF and a factor of 7 with 70% IPAF. However, this improved fluorescence using alkylammonium formates did not seem to be general for other coumarin compounds except for bromadiolone which showed a similar fluorescence enhancement using EAF. Enhancement of tryptophan fluorescence was also seen for both EAF and IPAF. During the reversed phase elution of LDH on a polymeric HPLC column, remarkable enhancements in LDH peak intensity and activity were observed by incorporating 6% PEG 8000 in the organic mobile phase that contained either 20% acetonitrile or IPAF. Using higher concentrations of PEG 8000 is not recommended, not only because of the high viscosity, but also because the stabilizing effect of PEG 8000 is gradually reduced at higher concentrations. PMID- 29576277 TI - The clinicopathological and prognostic significance of PD-L1 expression in pancreatic cancer: A meta-analysis. AB - BACKGROUND: Immunotherapy has shown promise against solid tumors. However, the clinical significance of programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) in pancreatic ductal adenocarcinoma (PDAC) remains unclear. This meta-analysis aimed to analyze the prognostic effect of PD-L1 in PDAC. DATA SOURCES: Electronic search of the PubMed, Cochrane Library and Web of Science was performed until December 2016. Through database searches, we identified articles describing the relationship between PD-L1 status and PDAC patient prognosis. Meta analysis was performed to investigate the relationship between PD-1 and overall survival (OS). RESULTS: Nine studies with 989 PDAC patients were included for PD L1 expression analysis. And 5 studies with 688 PDAC patients were included in the prognostic analysis. The PD-L1 positive rate measured by immunohistochemistry (IHC) was higher than that measured by polymerase chain reaction (PCR) (P < 0.001). PDAC patients with high expression levels of PD-L1 had significantly reduced OS (HR = 2.34; 95% CI: 1.78-3.08). Subgroup analysis showed that the prognostic effect of PD-L1 levels was similar between the IHC and PCR methods. The PD-L1 positive rate was associated with PDAC T stages; the PD-L1 positive rate in the T3-4 group was higher than that in the T1-2 group (OR = 0.37; P = 0.001). CONCLUSIONS: High PD-L1 expression levels predicted a poor prognosis in PDAC patients. Thus, PD-L1 status helps determine treatment in PDAC patients. PMID- 29576278 TI - A comparison of desensitization methods: Rituximab with/without plasmapheresis in ABO-incompatible living donor liver transplantation. AB - BACKGROUND: Plasmapheresis is a desensitization method used prior to ABO incompatible (ABO-I) living donor liver transplantation. However, studies on its usefulness in the rituximab era are lacking. METHODS: Fifty-six adult patients underwent ABO-I living donor liver transplantation between January 2012 and October 2015. A single dose of rituximab (300 mg/m2) was administered 2 weeks before surgery with plasmapheresis in all patients until February 2014 (RP group, n = 26). Patients were administered rituximab only, without plasmapheresis between March 2014 and October 2015 (RO group, n = 30). RESULTS: The 6-, 12- and 18-month overall survival rates were 92.3%, 80.8% and 76.9% in the RP group and 96.6%, 85.4% and 85.4% in the RO group, respectively (P = 0.574). When the initial isoagglutinin titers < 16, neither group showed a rebound rise of isoagglutinin titers. For patients with initial isoagglutinin titers >= 16, the rebound rise of isoagglutinin titers was more prominent in the RP group. There was no difference in time-dependent changes in B cell subpopulations and ABO-I related complications. CONCLUSIONS: Sufficient desensitization for ABO-I living donor liver transplantation can be achieved using rituximab alone. This desensitization strategy does not affect the isoagglutinin titers, ABO-I-related complications and patient survival. PMID- 29576279 TI - Prognostic factors and survival after surgical resection of pancreatic neuroendocrine tumor with validation of established and modified staging systems. AB - BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) display wide heterogeneity with highly variable prognosis. This study aimed to identify variables related to survival after surgical resection of PNET. METHODS: A total of 143 patients were identified from a prospectively maintained database. Patient characteristics were analyzed and prognostic factors for overall survival and progression-free survival were evaluated. The WHO, ENETS and AJCC scoring systems were applied to the cohort, and their ability to predict patient outcomes were compared. RESULTS: Multivariate analysis found that female gender, lymph node metastases and increasing WHO 2010 grade to be independently associated with reduced overall survival (P < 0.05). Patients requiring multi-visceral resection or debulking surgery found to be associated with shortest survival. ROC analysis found the ENETS and AJCC scoring systems to be similarly predictive of 5-year overall survival. Modified Ki67 significantly improved its accuracy in predicting 5-year overall survival (AUROC: 0.699 vs 0.605; P < 0.01). CONCLUSIONS: Multi-visceral or debulking surgery is associated with poor outcomes. There seems to be no significant difference between enucleation and anatomical segmental resection. Available scoring systems have reasonable accuracy in stratifying disease severity, with no system identified as being superior. Prognostic stratification with modified grading systems needs further validation before applied in clinical practice.

PMID- 29576281 TI - Public Health since the beginning: Neonatal incubators safety in a clinical setting. AB - BACKGROUND: The role of environmental cleaning as an effective measure to contain the diffusion of Healthcare Associated Infections (HAIs) has already been demonstrated. Among medical devices, neonatal incubators have been recognized as a source of pathogens involved in the spread of HAIs. Aim of the study was to assess the efficacy of a disinfection protocol for neonatal incubators. METHODS: The cross sectional study took place in the "Neonatal Pediatric Unit" of the Teaching Hospital of Siena: twenty incubators, used for critical newborns, were swabbed in 13 sampling points before and after the implementation of the disinfection protocol. Sanitation procedures were performed by trained staff, implementing the product Umonium38(r) Neutralis as disinfectant. Different culture media for the identification of the microbial contamination were adopted: plates were incubated for the proper time and the results were referred to Colony Forming Units (CFUs)/swab per point. Descriptive statistical analysis was performed. It was also evaluated the 95% confidence interval (C.I.) of the mean and the percentage of CFUs reduction by the bootstrap bias corrected and accelerated resampling method. RESULTS: Matched points analyzed were 313. The average CFUs percentage of reduction was 93.5% [C.I. 90.6-95.9%]: it was higher, 97.0% [C.I. 94.1-99.1%], in points placed inside the incubators structure compared to the 88.4% [C.I. 83.6-93.0%] obtained outside. CONCLUSION: The disinfection protocol achieved good results. Routine surveillance and supervision of the various aspects of the disinfection processes (procedures, staff and disinfectants) could guarantee a safe environment during the first days of babies' life, avoiding harmful conditions for the newborns' health. PMID- 29576282 TI - Engineering nanoparticle strategies for effective cancer immunotherapy. AB - Cancer immunotherapy has been emerging in recent years, due to the inherent nature of the immune system. Although recent successes of immunotherapeutics in clinical application have attracted development of a novel immunotherapeutics, the off-target side effect and low immunogenicity of them remain challenges for the effective cancer immunotherapy. Theranostic nanoparticle system may one of key technology to address these issues by offering targeted delivery of various types of immunotherapeutics, resulting in significant improvements in the tumor immunotherapy. However, appropriate design or engineering of nanoparticles will be needed to improve delivery efficiency of antigen, adjuvant and therapeutics, resulting in eliciting antitumor immunity. Here, we review the current state of the art of cancer immunotherapeutic strategies, mainly based on nanoparticles (NPs). This includes NP-based antigen/adjuvant delivery vehicles to draining lymph nodes, and tumor antigen-specific T-lymphocytes for cancer immunotherapy. Several NP-based examples are shown for immune checkpoint modulation and immunogenic cell death. These overall studies demonstrate the great potential of NPs in cancer immunotherapy. Finally, engineering NP strategies will provide great opportunities to improve therapeutic effects as well as optimization of treatment processes, allowing to meet the individual needs in the cancer immunotherapy. PMID- 29576283 TI - Armed oncolytic viruses: A kick-start for anti-tumor immunity. AB - Oncolytic viruses (OVs), viruses that specifically result in killing tumor cells, represent a promising class of cancer therapy. Recently, the focus in the OV therapy field has shifted from their direct oncolytic effect to their immune stimulatory effect. OV therapy can function as a "kick start" for the antitumor immune response by releasing tumor associated antigens and release of inflammatory signals. Combining OVs with immune modulators could enhance the efficacy of both immune and OV therapies. Additionally, genetic engineering of OVs allows local expression of immune therapeutics, thereby reducing related toxicities. Different options to modify the tumor microenvironment in combination with OV therapy have been explored. The possibilities and obstacles of these combinations will be discussed in this review. PMID- 29576284 TI - Type I interferon and HIV: Subtle balance between antiviral activity, immunopathogenesis and the microbiome. AB - Type I interferon (IFN) response initially limits HIV-1 spread and may delay disease progression by stimulating several immune system components. Nonetheless, persistent exposure to type I IFN in the chronic phase of HIV-1 infection is associated with desensitization and/or detrimental immune activation, thereby hindering immune recovery and fostering viral persistence. This review provides a basis for understanding the complexity and function of IFN pleiotropic activity in HIV-1 infection. In particular, the dichotomous role of the IFN response in HIV-1 immunopathogenesis will be discussed, highlighting recent advances in the dynamic modulation of IFN production in acute versus chronic infection, expression signatures of IFN subtypes, and viral and host factors affecting the magnitude of IFN response during HIV-1 infection.

AB - Hepatitis C virus (HCV) infection is a major public health problem despite effectual direct-acting antivirals (DAAs) therapy. Development of a prophylactic vaccine is essential to block spread of HCV infection. The HBV small surface antigen (HBsAg-S) can self-assemble into virus-like particles (VLPs), has higher immunogenicity and is used as a vaccine against HBV infections. Chimeric HBsAg-S proteins with foreign epitopes allow VLP formation and induce the specific humoral and cellular immune responses against the foreign proteins. In this study, we investigated the immune responses induced by chimeric VLPs with HCV neutralizing epitopes and HBV S antigen in mice. The chimeric HCV-HBV VLPs expressing neutralizing epitopes were prepared and purified. BALB/c mice were immunized with purified chimeric VLPs and the serum neutralizing antibodies were analyzed. We found that these chimeric VLPs induced neutralizing antibodies against HCV in mice. Additionally, the murine serum neutralized infections with HCV pseudoparticles and cell-cultured viruses derived from different heterologous 1a, 1b and 2a genotypes. We also found that immunization with chimeric VLPs induced anti-HBsAg antibodies. This study provides a novel strategy for development of a HCV prophylactic neutralizing epitope vaccine and a HCV-HBV bivalent prophylactic vaccine. PMID- 29576304 TI - A phase III, open-label, randomised multicentre study to evaluate the immunogenicity and safety of a booster dose of two different reduced antigen diphtheria-tetanus-acellular pertussis-polio vaccines, when co-administered with measles-mumps-rubella vaccine in 3 and 4-year-old healthy children in the UK. AB - AIM: To evaluate the immunogenicity and safety of a reduced antigen diphtheria tetanus-acellular pertussis-inactivated poliovirus (dTap-IPVB) vaccine (Boostrix IPV, GSK) as a pre-school booster in 3-4 year old children as compared to dTap IPVR (Repevax, Sanofi Pasteur), when co-administered with mumps-measles-rubella vaccine (MMRV). METHODS: This phase III, open label, randomised study was conducted in the UK between April 2011 and April 2012. Children due their pre school dTap-IPV booster vaccination were randomised 2:1 to receive one of two different dTap-IPV vaccines (dTap-IPVB or dTap-IPVR) with blood sample for immunogenicity assessment just prior and one month after vaccination. Immune responses to diphtheria, tetanus and polio antigens were compared between the study vaccines (inferential comparison). In the absence of an accepted pertussis correlate of protection, the immunogenicity of dTap-IPVB vaccine against pertussis was compared with historical pertussis efficacy data (inferential comparison). Safety and reactogenicity of both study vaccines were evaluated. RESULTS: 387 children were randomised and 385 vaccinated: 255 in the dTap-IPVB group and 130 in the dTap-IPVR group. Prior to vaccination, >=76.8% of children had anti-diphtheria and >=65.5% had anti-tetanus titres above the protection threshold; for pertussis, the pre-vaccination seropositivity rate ranged between 18.1 and 70.6%. Both vaccines were immunogenic with 99.2-100% of children achieving titres above the pre-specified seroprotection/seropositivity thresholds. One serious adverse event not considered as causally related to the study vaccination by the study investigator was reported in the dTap-IPVB group. CONCLUSION: Non-inferiority of dTap-IPVB to dTap-IPVR was demonstrated. Both vaccines had a clinically acceptable safety and reactogenicity profile when co administered with MMRV to children 3-4 years old. TRIAL REGISTRATION: NCT01245049 (ClinicalTrials.gov). PMID- 29576305 TI - A bibliometric analysis of systematic reviews on vaccines and immunisation. AB - INTRODUCTION: SYSVAC is an online bibliographic database of systematic reviews and systematic review protocols on vaccines and immunisation compiled by the London School of Hygiene & Tropical Medicine and hosted by the World Health Organization (WHO) through their National Immunization Technical Advisory Groups (NITAG) resource centre (www.nitag-resource.org). Here the development of the database and a bibliometric review of its content is presented, describing trends in the publication of policy-relevant systematic reviews on vaccines and immunisation from 2008 to 2016. MATERIALS AND METHODS: Searches were conducted in seven scientific databases according to a standardized search protocol, initially in 2014 with the most recent update in January 2017. Abstracts and titles were screened according to specific inclusion criteria. All included publications were coded into relevant categories based on a standardized protocol and subsequently analysed to look at trends in time, topic, area of focus, population and geographic location. RESULTS: After screening for inclusion criteria, 1285 systematic reviews were included in the database. While in 2008 there were only 34 systematic reviews on a vaccine-related topic, this increased to 322 in 2016. The most frequent pathogens/diseases studied were influenza, human papillomavirus and pneumococcus. There were several areas of duplication and overlap. DISCUSSION: As more systematic reviews are published it becomes increasingly time consuming for decision-makers to identify relevant information among the ever increasing volume available. The risk of duplication also increases, particularly given the current lack of coordination of systematic reviews on vaccine-related questions, both in terms of their commissioning and their execution. The SYSVAC database offers an accessible catalogue of vaccine-relevant systematic reviews with, where possible access or a link to the full-text. CONCLUSIONS: SYSVAC provides a freely searchable platform to identify existing vaccine-policy relevant systematic reviews. Systematic reviews will need to be assessed adequately for each specific question and quality. PMID- 29576306 TI - Porcine epidemic diarrhea vaccine efficacy evaluation by vaccination timing and frequencies. AB - Porcine epidemic diarrhea (PED) virus is a causative agent of enteric disease characterized by watery diarrhea and dehydration. Because PED has high morbidity and mortality, especially in suckling piglets, it causes a great economic loss to swine farms worldwide. Although various PED vaccines have been developed and commercialized, their efficacies are still controversial. In particular, current PED vaccination protocol (vaccination at 2 and 4 weeks before farrowing) may cause stress in pregnant sows. In this study, we compared the effects of PED vaccination timing and frequency for its efficacy by measuring the PED virus specific antibodies. We found that vaccination at early stages of pregnancy induces similar levels of serum and colostrum antibodies with those at late stages of pregnancy. As the number of vaccinations increased, the amounts of antibody in serum and colostrum, and neutralizing activities increased. Our results provide important information for establishing a more efficient PED vaccination protocol. PMID- 29576307 TI - Immunogenicity and safety of the quadrivalent meningococcal ACWY-tetanus toxoid conjugate vaccine (MenACWY-TT) in splenectomized or hyposplenic children and adolescents: Results of a phase III, open, non-randomized study. AB - BACKGROUND: Individuals with functional or anatomic asplenia are at high risk for meningococcal disease. We evaluated the immunogenicity and safety of 1 and 2 doses of the quadrivalent meningococcal serogroups A, C, W, Y tetanus toxoid conjugate vaccine (MenACWY-TT) in this high-risk population. METHODS: This phase III, open-label, controlled, non-randomized study (NCT01641042) enrolled 1-17 year-olds with impaired splenic activity (high-risk group) and age-matched healthy controls (control group). We measured immune responses to MenACWY-TT by serum bactericidal activity assays using rabbit (rSBA) and human (hSBA) complement and in terms of antibodies against polysaccharides of the 4 vaccine serogroups. We evaluated vaccine response rates (VRRs) as 4-fold increases from pre-vaccination levels or titers >=1:32 (rSBA)/>=1:8 (hSBA). We recorded solicited and unsolicited adverse events (AEs) during 4 and 31 days post vaccination, and serious AEs (SAEs) and new onset of chronic illnesses (NOCIs) throughout the study. RESULTS: The according-to-protocol cohort for immunogenicity included 40 participants per group. In both groups, the first MenACWY-TT dose induced rSBA VRRs of 92.5-100% and hSBA VRRs of 55.6-77.1% across vaccine serogroups. Following the second MenACWY-TT dose, all participants had high responses, with rSBA and hSBA VRRs of 73.0-100% across vaccine serogroups. rSBA and hSBA geometric mean titers for each serogroup increased in both groups (with different magnitudes, but >=13.1-fold) compared with baseline levels. Polysaccharide antibody concentrations >=2.0 MUg/ml were detected in >=84.4% of participants and were similar between groups. Incidences of solicited and unsolicited AEs were comparable between groups. We recorded SAEs in 4/43 participants in the high-risk group and 1/43 participants in the control group (none vaccine-related). No NOCIs were reported. CONCLUSION: In this descriptive study, MenACWY-TT induced similar functional and humoral immune responses and had a clinically acceptable safety profile in children and adolescents with impaired splenic activity and in healthy controls. PMID- 29576308 TI - A review of recommendations for rotavirus vaccination in Europe: Arguments for change. AB - BACKGROUND: More than 10 years after the authorisation of two rotavirus vaccines of demonstrated efficacy and with a strongly positive benefit-risk profile, uptake in Europe remains low. Only 13 countries in Europe provide a fully-funded rotavirus universal mass vaccination (UMV) programme, three provide a partially funded programme, and one provides full funding for a reduced programme targeting at-risk infants. Around 40% of countries in Europe currently have no existing recommendations for rotavirus vaccine use in children from the national government. METHODS: We provide an overview of the status of rotavirus vaccine recommendations across Europe and the factors impeding uptake. We consider the evidence for the benefits and risks of vaccination, and argue that cost effectiveness and cost-saving benefits justify greater access to rotavirus vaccines for infants living in Europe. RESULTS: Lack of awareness of the direct and indirect burden caused by rotavirus disease, potential cost-saving from rotavirus vaccination including considerable benefits to children, families and society, and government/insurer cost constraints all contribute to complacency at different levels of health policy in individual countries. CONCLUSIONS: More than 10 years after their introduction, available data confirm the benefits and acceptable safety profile of infant rotavirus UMV programmes. Europe serves to gain considerably from rotavirus UMV in terms of reductions in healthcare resource utilization and related costs in both vaccinated subjects and their unvaccinated siblings through herd protection. PMID- 29576309 TI - Preventive effect of oral hangeshashinto (TJ-14) on the development of reflux induced esophageal cancer. AB - BACKGROUND: Prostaglandin E2 is one of the potential products that promotes development of tumors and also is a strong inducer of M2 phenotype macrophages, which contribute to tumor development in the immunosuppressed microenvironment. Hangeshashinto (TJ-14), a Japanese traditional medicine (Kampo medicine), has been reported to be effective in preventing chemotherapy-induced oral mucositis through the reduction of prostaglandin E2. We previously developed a surgical rat reflux model of esophageal cancer and used this well-established animal model to investigate the action of TJ-14 in preventing esophageal cancer. We also assessed the effect of TJ-14 on the downregulation of prostaglandin E2 production, utilizing esophageal squamous cell carcinoma cell line exposed to bile acid. METHODS: An end-to-side esophagojejunostomy was performed for the reflux model. A daily oral diet was subsequently administered, consisting of either diet incorporated TJ-14 or standard diet as a control group. The rats were killed at 40 weeks after surgery. The incidence of esophageal cancer, Barrett's metaplasia, and proliferative hyperplasia were assessed histologically. CD163, a M2 phenotype macrophage marker, was assessed with immunohistochemistry. Prostaglandin E2 enzyme immunoassay and lactate dehydrogenase assay were performed on chenodeoxycholic acid or gastroesophageal reflux contents exposed to esophageal squamous cell carcinoma cell line. RESULTS: Sixty-seven percent of the controls (n = 12) developed esophageal cancer, but animals that received TJ-14 (n = 10) had a cancer incidence of 10% (P=.007). Barrett's metaplasia was found in 83% of the rats in the control group and 50% of the rats in the TJ-14 indicating a protective tendency of TJ-14 (P=.095). All of the rats developed proliferative hyperplasia. The number of M2 phenotype macrophage were significantly decreased in the TJ-14 group compared to the control group in both Barrett's metaplasia and esophageal cancer lesions. TJ-14 inhibited chenodeoxycholic acid or gastroesophageal reflux content-induced prostaglandin E2 production in esophageal squamous cell carcinoma cell. CONCLUSION: TJ-14 reduced the incidence of reflux induced esophageal cancer and the infiltration of M2 macrophages in a surgical rat model or suppressed prostaglandin E2 production in esophageal squamous cell carcinoma cell. Further investigation is required regarding the potential clinical use of TJ-14 as an esophageal cancer chemopreventive agent. PMID- 29576310 TI - Controlled drug release to the inner ear: Concepts, materials, mechanisms, and performance. AB - Progress in drug delivery to the ear has been achieved over the last few years. This review illustrates the main mechanisms of controlled drug release and the resulting geometry- and size-dependent release kinetics. The potency, physicochemical properties, and stability of the drug molecules are key parameters for designing the most suitable drug delivery system. The most important drug delivery systems for the inner ear include solid foams, hydrogels, and different nanoscale drug delivery systems (e.g., nanoparticles, liposomes, lipid nanocapsules, polymersomes). Their main characteristics (i.e., general structure and materials) are discussed, with special attention given to underlining the link between the physicochemical properties (e.g., surface areas, glass transition temperature, microviscosity, size, and shape) and release kinetics. An appropriate characterization of the drug, the excipients used, and the formulated drug delivery systems is necessary to achieve a deeper understanding of the release process and decrease variability originating from the drug delivery system. This task cannot be solved by otologists alone. The interdisciplinary cooperation between otology/neurotology, pharmaceutics, physics, and other disciplines will result in improved drug delivery systems for the inner ear. PMID- 29576311 TI - Inter-joint coordination of kinematics and kinetics before and after total hip arthroplasty compared to asymptomatic subjects. AB - While differences in joint kinematics and kinetics between control subjects and patients before and after total hip arthroplasty (THA) has often been studied, inter-joint coordination has not been fully characterized. We hypothesized that in patients undergoing THA, inter-joint coordination (i) is different from control subjects before surgery, (ii) changes from pre-operative to post operative, and (iii) remains different from control subjects after surgery. Seventy-eight subjects underwent gait analysis before and ~1 year after primary unilateral THA. 109 control subjects were age, sex, and BMI matched to the THA group. We selected a representative trial at each subjects' self-selected walking speed from a motion analysis data repository. To assess kinematic coordination, we constructed sagittal plane hip-knee angle cyclograms, and calculated total, stance, and swing phase plot area (deg2). To assess kinetic coordination, we calculated the support moment (MS, %wt * ht), the time-integral of support moment (MS impulse, %wt * ht * t), and the relative contribution of each joint to MS impulse (%Hip, %Knee, %Ankle). We used t-tests to compare groups. Total and swing phase cyclogram area was smaller preoperatively, but improved to control values after THA. Swing-phase area was smaller than control values after THA. MS impulse was larger in THA subjects than controls both before and after surgery. While, the relative contribution of the hip to MS impulse was not different from control values, the contributions of the knee and ankle were smaller. Inter-joint coordination, as measured by hip-knee angle cyclograms and MS impulse, may be used to distinguish differences in gait mechanics between osteoarthritis and THA. Future work focusing on coordination among joints may be needed to fully restore gait function. PMID- 29576312 TI - Directional bias of soft-tissue artifacts on the acromion during recording of 3D scapular kinematics. AB - Scapular kinematics during sports performances can be recorded using skin-mounted trackers attached to the skin overlying the acromion for continuous data collection without restricting natural motions of the subject relative to medical imaging analyses limiting its use for wide-range or high-speed motions. This study aimed to describe the existence of a directional bias in the translational and rotational errors of skin-mounted trackers using a 3D magnetic resonance imaging (3D-MRI) protocol. 3D-MRI scans of the healthy right shoulders of 19 males were acquired in 12 arm positions. The relative transformation of the scapular configuration determined to be the measurement error, as recorded by the configuration of the small cuboid imitating a skin-mounted tracker relative to the actual scapular configuration measured by the voxel-based registration. These measurement errors were expressed with either positive or negative values to describe the bias. Overall translational errors in the lateral, anterior, and superior directions were 3.7 +/- 8.4 mm, 9.5 +/- 6.4 mm, and 6.2 +/- 4.6 mm, respectively. Overall rotational errors in protraction, upward rotation, and posterior tilt were 7.8 +/- 8.4 degrees , 0.2 +/- 7.4 degrees , and - 4.0 +/- 7.5 degrees , respectively. The skin-mounted tracker displayed a high probability of displacement in antero-superior (93% and 91%) directions and rotates in a protracting manner (82%) relative to the position of the underlying bone with the gradual nature of its change. The existence of the directional bias with its gradual change suggests a statistical predictability in measurement errors, which can be used to predict accurate scapular translation and rotation. PMID- 29576313 TI - Training induced changes in quadriceps activation during maximal eccentric contractions. AB - Despite full voluntary effort, neuromuscular activation of the quadriceps group of muscles appears inhibited during eccentric contractions. A nerve stimulation protocol during dynamic contractions of the quadriceps was developed that employed triplets of supramaximal pulses to assess suppressed eccentric activation. Subsequently the effects of a short training intervention, performed on a dynamometer, on eccentric strength output and neural inhibition were examined. Torque-angular velocity (T-omega) and experimental voluntary neural drive-angular velocity (%VA-omega; %VA, obtained via the interpolated twitch technique) datasets, were obtained from pre- and post-training testing sessions. Non-linear regression fits of a seven parameter torque function and of a 3rd degree polynomial were performed on the pre- and post-training T-omega and %VA omega datasets respectively. T-test showed a significant (p < 0.05) increase in the overall torque output post-training for the group, with three out of the six subjects demonstrating a significant (p < 0.05) increase in the torque output across the range of angular velocities as shown by the extra-sum-of-squares F test. A significant increase (p < 0.05) in the %VA post-training was also observed as well as a reduction in the plateauing of the torque output during fast eccentric contractions. PMID- 29576314 TI - Position of the quadriceps actuator influences knee loads during simulated squat testing. AB - The "Oxford Rig" cadaveric simulator permits researchers and clinicians to study knee mechanics during a simulated squatting motion. The motion of the lower limb in the Oxford Rig is typically controlled by a single actuator that applies tension to the quadriceps tendon. The location of the quadriceps actuator, however, has differed across published descriptions of the Oxford Rig. Actuators have been placed on the femur and pelvis, and on "grounded" locations external to the specimen, but the consequences of this placement for knee kinematics and kinetics are unknown. The purpose of this study was to examine these effects using a validated computational musculoskeletal model. When the actuator was placed on the femur or pelvis, forces realistically increased with knee flexion, with quadriceps and patellofemoral contact forces exceeding 2000 N and 3000 N, respectively, at 100 degrees flexion. When the actuator was grounded, however, forces were substantially reduced and did not monotonically increase with flexion. Articular joint contact forces were not strongly influenced by changing the location of the actuator from the femur to the pelvis, with small RMS differences in quadriceps forces (48.2 N), patellofemoral forces (83.6 N), and tibiofemoral forces (58.9 N) between these conditions. The location of the actuator did not substantially affect knee kinematics. The results of this study suggest that the quadriceps actuator of the Oxford Rig should be attached to either the femur or the pelvis when the goal is to make realistic estimates of quadriceps forces and articular contact forces within the knee joint. PMID- 29576316 TI - Glycosylation in cancer: Selected roles in tumour progression, immune modulation and metastasis. AB - Tumour metastasis is the main cause of cancer related deaths. Metastasis is an intricate multi-step process that requires the acquisition of several cancer cell features, including the modulation of tumour cell migration, adhesion, invasion, and immune evasion. Changes in the cellular glycosylation are associated with malignant transformation of cancer cells, tumour progression and ultimately, metastasis formation. Glycans have major impact on cellular signalling and on the regulation of tumour cell-cell adhesion and cell-matrix interaction. Glycans drive the interplay between the cancer cells and the tumour microenvironment. In this review, we summarize the roles of glycan alterations in tumour progression, such as acquisition of oncogenic features due to modulation of receptor tyrosine kinases, proteoglycans, cadherins and integrins. We also highlight the importance of key glycan binding proteins such as selectins, siglecs and galectins, which are pivotal in the modulation of immune response. An overview on glycans as cancer biomarkers is also presented. PMID- 29576315 TI - Liver induced transgene tolerance with AAV vectors. AB - Immune tolerance is a vital component of immunity, as persistent activation of immune cells causes significant tissue damage and loss of tolerance leads to autoimmunity. Likewise, unwanted immune responses can occur in inherited disorders, such as hemophilia and Pompe disease, in which patients lack any expression of protein, during treatment with enzyme replacement therapy, or gene therapy. While the liver has long been known as being tolerogenic, it was only recently appreciated in the last decade that liver directed adeno-associated virus (AAV) gene therapy can induce systemic tolerance to a transgene. In this review, we look at the mechanisms behind liver induced tolerance, discuss different factors influencing successful tolerance induction with AAV, and applications where AAV mediated tolerance may be helpful. PMID- 29576317 TI - Structures of the Gasdermin D C-Terminal Domains Reveal Mechanisms of Autoinhibition. AB - Pyroptosis is an inflammatory form of programmed cell death that plays important roles in immune protection against infections and in inflammatory disorders. Gasdermin D (GSDMD) is an executor of pyroptosis upon cleavage by caspases 1/4/5/11 following canonical and noncanonical inflammasome activation. GSDMD N terminal domain assembles membrane pores to induce cytolysis, whereas its C terminal domain inhibits cell death through intramolecular association with the N domain. The molecular mechanisms of autoinhibition for GSDMD are poorly characterized. Here we report the crystal structures of the human and murine GSDMD C-terminal domains, which differ from those of the full-length murine GSDMA3 and the human GSDMB C-terminal domain. Mutations of GSDMD C-domain residues predicted to locate at its interface with the N-domain enhanced pyroptosis. Our results suggest that GSDMDs may employ a distinct mode of intramolecular domain interaction and autoinhibition, which may be relevant to its unique role in pyroptosis downstream of inflammasome activation. PMID- 29576318 TI - A Structural Model of the Urease Activation Complex Derived from Ion Mobility Mass Spectrometry and Integrative Modeling. AB - The synthesis of active Klebsiella aerogenes urease via an 18-subunit enzyme apoprotein-accessory protein pre-activation complex has been well studied biochemically, but thus far this complex has remained refractory to direct structural characterization. Using ion mobility-mass spectrometry, we characterized several protein complexes between the core urease apoprotein and its accessory proteins, including the 610-kDa (UreABC)3(UreDFG)3 complex. Using our recently developed computational modeling workflow, we generated ensembles of putative (UreABC)3(UreDFG)3 species consistent with experimental restraints and characterized the structural ambiguity present in these models. By integrating structural information from previous studies, we increased the resolution of the ion mobility-mass spectrometry-derived models substantially, and we observe a discrete population of structures consistent with all of the available data for this complex. PMID- 29576319 TI - Structure-Function Relationship of the Bik1-Bim1 Complex. AB - In budding yeast, the microtubule plus-end tracking proteins Bik1 (CLIP-170) and Bim1 (EB1) form a complex that interacts with partners involved in spindle positioning, including Stu2 and Kar9. Here, we show that the CAP-Gly and coiled coil domains of Bik1 interact with the C-terminal ETF peptide of Bim1 and the C terminal tail region of Stu2, respectively. The crystal structures of the CAP-Gly domain of Bik1 (Bik1CG) alone and in complex with an ETF peptide revealed unique, functionally relevant CAP-Gly elements, establishing Bik1CG as a specific C terminal phenylalanine recognition domain. Unlike the mammalian CLIP-170-EB1 complex, Bik1-Bim1 forms ternary complexes with the EB1-binding motifs SxIP and LxxPTPh, which are present in diverse proteins, including Kar9. Perturbation of the Bik1-Bim1 interaction in vivo affected Bik1 localization and astral microtubule length. Our results provide insight into the role of the Bik1-Bim1 interaction for cell division, and demonstrate that the CLIP-170-EB1 module is evolutionarily flexible. PMID- 29576320 TI - The Helix Rearrangement in the Periplasmic Domain of the Flagellar Stator B Subunit Activates Peptidoglycan Binding and Ion Influx. AB - The stator of the bacterial flagellar motor couples ion flow with torque generation. The ion-conducting stator channel opens only when incorporated into and anchored around the rotor via the peptidoglycan (PG) binding domain of the B subunit (MotBC). However, no direct evidence of PG binding coupled with channel activation has been presented. Here, we report the structural rearrangements of MotBC responsible for this coupling process. A MotBC fragment with the L119P replacement, which is known to cause channel activation, was able to bind PG. Nuclear magnetic resonance analysis of MotBC and the crystal structure of the MotBC-L119P dimer revealed major structural changes in helix alpha1. In vivo crosslinking results confirm that a major rearrangement occurs. Our results suggest that, upon stator incorporation into the motor, helix alpha1 of MotBC changes into an extended non-helical structure. We propose that this change allows the stator both to bind PG and to open its proton channel. PMID- 29576321 TI - An Intracellular Allosteric Modulator Binding Pocket in SK2 Ion Channels Is Shared by Multiple Chemotypes. AB - Small conductance potassium (SK) ion channels define neuronal firing rates by conducting the after-hyperpolarization current. They are key targets in developing therapies where neuronal firing rates are dysfunctional, such as in epilepsy, Parkinson's, and amyotrophic lateral sclerosis (ALS). Here, we characterize a binding pocket situated at the intracellular interface of SK2 and calmodulin, which we show to be shared by multiple small-molecule chemotypes. Crystallization of this complex revealed that riluzole (approved for ALS) and an analog of the anti-ataxic agent (4-chloro-phenyl)-[2-(3,5-dimethyl-pyrazol-1-yl) pyrimidin-4-yl]-amine (CyPPA) bind to and allosterically modulate via this site. Solution-state nuclear magnetic resonance demonstrates that riluzole, NS309, and CyPPA analogs bind at this bipartite pocket. We demonstrate, by patch-clamp electrophysiology, that both classes of ligand interact with overlapping but distinct residues within this pocket. These data define a clinically important site, laying the foundations for further studies of the mechanism of action of riluzole and related molecules. PMID- 29576322 TI - Evidence for association of STAT4 and IL12RB2 variants with Myasthenia gravis susceptibility: What is the effect on gene expression in thymus? AB - Myasthenia gravis (MG) is an autoimmune disease mediated by the presence of autoantibodies that bind mainly to the acetylcholine receptor (AChR) in the neuromuscular junction. In our case-control association study, we analyzed common variants located in genes of the IL12/STAT4 and IL10/STAT3 signaling pathways. A total of 175 sporadic MG patients of Greek descent, positively detected with anti AChR autoantibodies and 84 ethnically-matched, healthy volunteers were enrolled in the study. Thymus samples were obtained from 16 non-MG individuals for relative gene expression analysis. The strongest signals of association were observed in the cases of rs6679356 between the late-onset MG patients and controls and rs7574865 between early-onset MG and controls. Our investigation of the correlation between the MG-associated variants and the expression levels of each gene in thymus did not result in significant differences. PMID- 29576323 TI - Immunomodulatory treatment with systemic GM-CSF augments pulmonary immune responses and improves neurological outcome after experimental stroke. AB - Stroke-induced immunodepression is an independent risk factor for stroke associated pneumonia (SAP). Granulocyte-macrophage colony stimulating factor (GM CSF) has neuroprotective properties in experimental stroke and been demonstrated to reverse immunodepression in sepsis patients. However, whether GM-CSF restores immune function after stroke preventing SAP and improving outcome is unknown. Here, we demonstrated that GM-CSF treatment improved peripheral and pulmonary leukocyte numbers, peripheral cytokine responses, lowered lung bacterial burden in the early course and improved long-term functional outcome after experimental stroke. These data suggest that GM-CSF is promising for stroke treatment since it not only acts neuroprotective in the ischemic brain but may also protect against detrimental post-stroke infections. PMID- 29576324 TI - Prevalence of Nail Scabies: A French Prospective Multicenter Study. AB - INTRODUCTION: To assess the prevalence of nail involvement in children <16 years old with a confirmed diagnosis of scabies. STUDY DESIGN: Observational, prospective study in 7 French dermatology departments between June 2015 and January 2017. Children were included if they had scabies confirmed by dermoscopy and/or microscopy and if nails could be sampled. The first toenails and thumbnails as well as clinically affected nails were systematically sampled for microscopic examination. Individual data were recorded via a standardized questionnaire. RESULTS: A total of 47 children with scabies were included (26 females [55.3%], mean age 3.6 +/- 4.0 years). Pruritus was present in 42 children (89.3%); the relapse rate was 38.3% (n = 18). In 3 infants (6.4%), Sarcoptes mites were revealed by dermoscopy or microscopy of the first toenails (2 cases) and a thumbnail (1 case), but nails were normal in 2 children. Two of the 3 infants had already received treatment for scabies in the previous weeks. CONCLUSION: Prevalence of nail involvement in children with confirmed scabies was 6.4%. Nails should not be overlooked during scabies treatment. PMID- 29576325 TI - Adjunct Targeted Biologic Inhibition Agents to Treat Aggressive Multivessel Intraluminal Pediatric Pulmonary Vein Stenosis. AB - OBJECTIVE: To evaluate the use of imatinib mesylate with or without bevacizumab targeting neoproliferative myofibroblast-like cells with tyrosine kinase receptor expression, as adjuncts to modern interventional therapies for the treatment of multivessel intraluminal pulmonary vein stenosis (PVS). We describe the 48- and 72-week outcomes among patients receiving imatinib mesylate with or without bevacizumab for multivessel intraluminal PVS. STUDY DESIGN: This single-arm, prospective, open-label US Food and Drug Administration approved trial enrolled patients with >=2 affected pulmonary veins after surgical or catheter-based relief of obstruction between March 2009 and December 2014. Drug therapy was discontinued at 48 weeks, or after 24 weeks of stabilization, whichever occurred later. RESULTS: Among 48 enrolled patients, 5 had isolated PVS, 26 congenital heart disease, 5 lung disease, and 12 both. After the 72-week follow-up, 16 patients had stabilized, 27 had recurred locally without stabilization, and 5 had progressed. Stabilization was associated with the absence of lung disease (P = .03), a higher percentage of eligible drug doses received (P = .03), and was not associated with age, diagnosis, disease laterality, or number of veins involved. Survival to 72 weeks was 77% (37 of 48). Adverse events were common (n = 1489 total), but only 16 were definitely related to drug treatment, none of which were serious. CONCLUSION: Survival to 72 weeks was 77% in a referral population with multivessel intraluminal PVS undergoing multimodal treatment, including antiproliferative tyrosine kinase blockade. Toxicity specific to tyrosine kinase blockade was minimal. PMID- 29576326 TI - Remission in CBT for adult anxiety disorders: A meta-analysis. AB - Currently there is no universally accepted definition of remission in anxiety disorders. This may be causing significantly different estimates of treatment efficacy across anxiety disorders. The aim of this paper was to determine not only the overall remission rate in cognitive-behavioral therapy (CBT) for anxiety disorders, but also to examine whether the different definitions of remission lead to significantly different remission rates. From the initial 228 abstracts reviewed by the authors, 100 articles were retained. The overall mean remission rate was 51.0%. Remission rates were highest when remission was defined as good end state functioning or no longer meeting criteria for the primary diagnosis. Studies of posttraumatic stress disorder had the highest remission rates, while those of obsessive-compulsive disorder and social anxiety disorder had the lowest remission rates. Rates of remission differed by certain demographic (e.g., older age) and clinical (e.g., medication use) characteristics. Although CBT is an empirically supported treatment for anxiety disorders, it is clear that there is room for improvement, as many patients do not achieve remission status. PMID- 29576327 TI - Parental mosaicism in RYR1-related Central Core Disease. AB - Myopathies due to mutations in the skeletal muscle ryanodine receptor (RYR1) gene are amongst the most common non-dystrophic neuromuscular disorders and have been associated with both dominant and recessive inheritance. Several cases with apparently de novo dominant inheritance have been reported. Here we report two siblings with features of Central Core Disease (CCD) born to unaffected parents. Genetic testing revealed a heterozygous dominant RYR1 c.14582G>A (p. Arg4861His) mutation previously identified in other CCD pedigrees. The variant was absent in blood from the asymptomatic mother but detected at low but variable levels in blood- and saliva-derived DNA from the unaffected father, suggesting that this mutation has arisen as a paternal post-zygotic de novo event. These findings suggest that parental mosaicism should be considered in RYR1-related myopathies, and may provide one possible explanation for the marked intergenerational variability seen in some RYR1 pedigrees. PMID- 29576328 TI - Mitophagy: A Mechanism for Plant Growth and Survival. AB - Mitophagy is a conserved cellular process that is important for autophagic removal of damaged mitochondria to maintain a healthy mitochondrial population. Mitophagy also appears to occur in plants and has roles in development, stress response, senescence, and programmed cell death. However, many of the genes that control mitophagy in yeast and animal cells are absent from plants, and no plant proteins marking defunct mitochondria for autophagic degradation are yet known. New insights implicate general autophagy-related proteins in mitophagy, affecting the senescence of plant tissues. Mitophagy control and its importance for energy metabolism, survival, signaling, and cell death in plants are discussed. Furthermore, we suggest mitochondrial membrane proteins containing ATG8 interacting motifs, which might serve as mitophagy receptor proteins in plant mitochondria. PMID- 29576329 TI - Climate Change and Insect Pests: Resistance Is Not Futile? AB - Chemical signals produced by plants when attacked by herbivores play a crucial role in efficient plant defence. A recent study suggests that herbivore-specific R-gene resistance may be enhanced by elevated atmospheric CO2 concentrations. Understanding how climate change affects plant resistance to herbivorous pests could be essential for future food security. PMID- 29576331 TI - [Punctal agenesis with fusion of the two canaliculi: A very rare congenital malformation]. PMID- 29576330 TI - Intralacrimal migration of Masterka(r) stents. AB - BACKGROUND: Tearing and conjunctivitis in children are commonly due to lacrimal drainage system obstruction. Congenital nasolacrimal obstruction is a common pathology treated by probing with or without silicone stent insertion, depending upon the age of the child. The silicone stent is self-retaining and placed for at least one month. Masterka(r) is a recent version of Monoka(r), which may lead to the same surgical complications, such as intralacrimal migration. SUBJECTS AND METHODS: The medical records of two patients surgically treated with the Masterka(r) probe for nasolacrimal duct obstruction, who developed intralacrimal migration of the stent, were retrospectively reviewed and analyzed. A 41-month old child and an 18-month-old child presented with disappearance of the silicone tube after 7 days and 2 years respectively. In the first case, the tube migrated completely within the lacrimal system and became externalized through the nose at 2 years, while in the second case, the Masterka(r) was retrieved through a canalicular approach. In both cases, infants had no further tearing. DISCUSSION: The frequency self-retaining stent disappearance is estimated at 15%. Among these cases, intralacrimal migration is only reported in 0.5% of cases. To prevent intralacrimal migration, the surgical technique must follow a certain number of rules. Management, based on residual epiphora, is discussed. CONCLUSION: Prevention of intralacrimal migration of self-retaining stents involves a rigorous analysis of the relationship between the meatus and the fixation head at the time of placement. After lacrimal intubation, scheduled monitoring is necessary to screen for stent disappearance. Management is based on clinical findings, anterior rhinoscopy and even exploratory canaliculotomy. PMID- 29576332 TI - Ultrasound-guided embryo transfer: summary of the evidence and new perspectives. A systematic review and meta-analysis. AB - Despite the purported advantages of ultrasound guidance during embryo transfer, and the large number of clinical trials published on this topic, recommendations for the use of this technique in daily clinical practice are still under debate. We designed a meta-analysis based exclusively on evidence from published randomized controlled trials, with the aim of analysing the effect of trans abdominal ultrasound guidance during embryo transfer versus clinical touch and of transvaginal ultrasound guidance (TV-US) versus the trans-abdominal approach on IVF outcomes. On the basis of 14 randomized trials, we found a moderate quality of evidence supporting the beneficial effects of transabdominal guidance during embryo transfer compared with conventional clinical touch in clinical pregnancy and ongoing or live birth rates. No significant differences were found in miscarriage and ectopic pregnancy rate, with low or very low quality of evidence, respectively. On the basis of three randomized trials, we found the quality of evidence supporting the equivalence of transvaginal versus transabdominal approach in clinical pregnancy and ongoing or live birth rates to be low. Finally, larger randomized controlled trials are necessary to explore the possible benefits of TV-US, three-dimensional ultrasound imaging modality, and uterine length measurement before transfer. PMID- 29576333 TI - Enhancing Participation in Cardiac Rehabilitation: A Question of Proximity and Integration of Outpatient Services. AB - Numerous investigations have established the strong clinical utility of cardiac rehabilitation, while clinical guidelines continually call for a high level of referral and participation. Historically, medical facilities have faced challenges referring eligible patients to cardiac rehabilitation, enrolling only a small portion of those receiving referral. Consequently, less than ~10% of qualifying patients receive any amount of cardiac rehabilitation. This sobering figure has prompted many efforts to identify barriers to referral as well as enrollment and accordingly propose strategies to bolster participation rates. Although reports have highlighted improvements through focused approaches, enrollment rates still lag behind the goal of reaching 70% by 2022, proposed by the Million Hearts Cardiac Rehabilitation Collaborative. An area of inquiry that has received little to no attention in this effort has been the influence of proximity between physician-driven outpatient clinics and cardiac rehabilitation facilities. In this report we outline the development and design of a clinical faculty practice aimed to maintainclose geographical proximity between our physicianclinic and the cardiac rehabilitation area. We also propose that our impressive enrollment rates of 57% within our facility and 73% when including patients that started alternative exercise programs were likely due to establishing a close proximity between the respective practices. PMID- 29576334 TI - A cost-effectiveness analysis of lowering residential radon levels in Sweden Results from a modelling study. AB - PURPOSE: Residential exposure to radon is considered as the second leading cause of lung cancer after smoking. The purpose of this study was to conduct a cost effectiveness analysis of reducing the indoor radon levels in Sweden from the current reference level of 200 Bq/m3 to the WHO suggested reference level of maximum 100 Bq/m3. METHODS: We constructed a decision-analytic cost-effectiveness model using input data from published literature and administrative records. The model compared the increase in economic costs to the health benefits of lower indoor radon-levels in a Swedish policy context. We estimated the cost per life year and quality adjusted life year (QALY) gained and assessed the robustness of the results using both deterministic and probabilistic sensitivity analysis. RESULTS: Including (excluding) costs of added life years the cost per QALY for existing homes was ?130,000 (?99,000). For new homes the cost per QALY including (excluding) costs of added life years was ?39,000 (?25,000). CONCLUSIONS: The results indicate that it is not cost-effective to reduce indoor radon levels from 200 Bq/m3 to a maximum of 100 Bq/m3 in existing homes, whereas it is cost effective for new homes. PMID- 29576335 TI - Limited Adherence to Peripheral Arterial Disease Guidelines and Suboptimal Ankle Brachial Index Reliability in Dutch Primary Care. AB - OBJECTIVE/BACKGROUND: The Dutch College of General Practitioners' guideline on peripheral arterial disease (PAD) provides clear recommendations on the management of PAD. An ankle brachial index (ABI) measurement, prescription of antiplatelet drugs and statins, and supervised exercise therapy (SET) for intermittent claudication (IC) are advised. The aims of this study were to determine the adherence of general practitioners (GPs) to their own guideline on PAD and to evaluate the reliability of primary care ABI measurements. METHODS: This was a cross-sectional study. All patients suspected of having symptomatic PAD who were referred by GPs to a large hospital in 2015 were evaluated regarding three of the guideline criteria: (i) ABI measurement; (ii) prescription of secondary prevention; (iii) initiation of SET. ABI values obtained in primary care and the hospital's vascular laboratory were compared using correlation coefficients and regression analysis. An abnormal ABI was defined as a value <.9 (normal ABI >=.9). RESULTS: Of 308 potential patients with new onset PAD, 58% (n = 178) had undergone ABI measurement prior to referral. A modest correlation between ABI values obtained in primary care and the vascular laboratory was found (r = .63, p < .001). Furthermore, a moderate reliability was calculated (intraclass correlation coefficient 0.60, 95% confidence interval 0.49-0.69, p < .001). Of the new patients with an abnormal ABI, 59% used antiplatelet drugs and 55% used statins. A referral for SET was initiated by a GP in 10% of new PAD patients with IC symptoms. CONCLUSIONS: Adherence by Dutch GPs to their own society's PAD guideline has room for improvement. The reliability of ABI measurements is suboptimal, whereas rates of prescription of secondary prevention and initiation of SET as primary treatment for IC need upgrading. PMID- 29576336 TI - The Impact of Suprarenal Fixation on Renal Function Following Endovascular Abdominal Aortic Aneurysm Repair: Meta-analysis Based on Estimated Glomerular Filtration Rate. AB - BACKGROUND: Endovascular abdominal aortic aneurysm (AAA) repair (EVAR) is currently used routinely to treat AAA. Suprarenal fixation (SRF) of EVAR grafts can lead to renal dysfunction. A meta-analysis of studies using estimated glomerular filtration rate (eGFR) as a measure of renal injury to assess the effect of SRF on renal function was performed. METHODS: An electronic search was carried out to identify all articles that reported on renal injury following SRF versus infrarenal fixation (IRF) EVAR, and 24 studies were identified. Formal meta-analysis was used to assess eGFR drop at 1 and 5 years. The primary outcome measure was a drop in eGFR >20% at 1 year; secondary measures included eGFR drop >20% at 5 years and "renal dysfunction" based on the definition used in each publication. RESULTS: Five series reported eGFR reduction >20% at 1 year. The weighted odds ratio (OR) was 1.53 (95% CI 0.67-3.51, p = .31, I2 = 53.2%); 9.3% for SRF versus 7.4% for IRF. One study reported eGFR based renal dysfunction at 5 years: OR 1.77 (95% CI 1.04-3.02, p = .03); 16.9% for SRF versus 10.3% for IRF. Nineteen series reported some form of renal dysfunction (5287 SRF vs. 4386 IRF patients, mean follow up: 20.5 months, range 72 h to 5 years). The weighted OR was 1.32 (95% CI 1.01-1.71, p = .03, I2 = 28.4%); 5.1% for SRF versus 4.6% for IRF. "Renal dysfunction" definitions varied greatly and were based on creatinine or other inaccurate methods. CONCLUSION: EVAR using SRF does not lead to a significant drop in renal function at 1 year, based on eGFR. Long-term results are limited. Authors should report long-term renal injury using eGFR and not inaccurate arbitrary measures, which are currently common in the literature. PMID- 29576337 TI - A Feasibility Study of a New Unibody Branched Stent Graft Applied to Reconstruct the Canine Aortic Arch. AB - OBJECTIVES: The aim was to evaluate the feasibility and safety of a new unibody branched stent graft for the reconstruction of the canine aortic arch. METHODS: The unibody branched stent grafts included single branched stent grafts and double branched stent grafts. The main stent graft and branched limbs were sutured together. The branched stent grafts were folded into the introducer system, which consisted of a double channel catheter, a detachable sleeve, and an introducer sheath. The branched stent grafts were introduced and deployed into the aortic arch by the delivery system. Twenty adult mongrel dogs were used for the experiments. Ten dogs were implanted with single branched stent grafts; the other 10 were implanted with double branched stent grafts. The surviving animals were followed up for 3 months. Computed tomography angiography (CTA) was performed to observe the status of the branched stent grafts. RESULTS: All the unibody branched stent grafts were successfully implanted into the canine aortic arches. The technical success rate was 100%. There was no cerebral infarction, paraplegia or incision infection. CTA showed that all the branched stent grafts were patent; there was no endoleak or stent migration. CONCLUSIONS: The unibody branched stent graft system could be used to reconstruct the aortic arch. The animal experimental procedures demonstrated the safety and feasibility of the unibody branched stent graft system. PMID- 29576338 TI - Following ulnar collateral ligament reconstruction, professional baseball position players return to play faster than pitchers, but catchers return less frequently. AB - BACKGROUND: Although much as been done to characterize trends of medial ulnar collateral ligament (UCL) reconstruction in pitchers, outcomes in position players (PPs) (non-pitchers) remain undefined in the current literature. METHODS: Three resources were combined to identify all known Major League Baseball and Minor League Baseball (MiLB) PPs who have ever undergone UCL reconstruction. A multitude of player and surgical variables were included. Trends over time were analyzed collectively, based on level of play, revision status (primary vs revision), and position. Additional comparisons were made with a known cohort of professional baseball pitchers having undergone UCL reconstruction. RESULTS: We identified 168 UCL reconstructions in professional PPs. The annual rate of primary UCL reconstruction rose significantly from 1984 to 2015 (P < .001), and the proportion of cases performed in MiLB PPs (vs Major League Baseball PPs) increased steadily (P < .001). Of PPs, 75.5% returned to play at any level at a mean of 342 days. Catchers demonstrated the lowest return-to-play (RTP) rate (58.6%) compared with infielders (75.6%) and outfielders (88.9%). The overall revision rate was low, at 4.8%. Compared with pitchers, PPs demonstrated a lower rate of RTP (75.5% for PPs vs 83.7% for pitchers, P = .040) but shorter RTP times for those able to return (342 days for PPs vs 435 days for pitchers, P < .001). CONCLUSIONS: The incidence of UCL reconstruction in PPs continues to rise, a trend that is significantly more pronounced at the MiLB level. Although PPs (particularly catchers) are less likely to return to professional baseball compared with pitchers, those who are able to RTP do so more rapidly. PMID- 29576339 TI - Early return to baseline range of motion and strength after anterior shoulder instability surgery: a Multicenter Orthopaedic Outcomes Network (MOON) shoulder group cohort study. AB - BACKGROUND: Patients often return to higher-level activities and sports at 4 to 8 months after anterior shoulder stabilization procedures. It is unknown what percentage of patients have regained normal function at this time frame and what factors predict residual deficits, range of motion (ROM), and strength after anterior shoulder instability surgery. METHODS: Ten participating sites throughout the United States enrolled patients in a prospective cohort study including primary, revision, arthroscopic, and open anterior stabilization procedures. Baseline demographic data and patient outcomes questionnaires were collected with initial physical examination, treatment, surgical findings, and surgical repair details. At the 6-month follow-up visit, ROM and strength measurements were collected and compared with preoperative measurements. RESULTS: There were 348 patients identified who underwent surgical treatment for anterior shoulder instability. Of these, 259 patients (74.0%) returned to baseline, and 89 (26.0%) did not return to baseline shoulder ROM (>=20 degrees loss of ROM) or strength. A higher Beighton score (P = .01) and number of dislocations (P < .01) were associated with failure to regain baseline ROM and strength at early follow up. No surgical variables were found to influence return to baseline function, including open vs. arthroscopic surgery, primary vs. revision surgery, and number of suture anchors. CONCLUSIONS: By 4 to 8 months postoperatively, 76% of patients return to baseline ROM, 98% return to baseline strength, and 74% return to both baseline ROM and strength. An increased number of dislocations and generalized joint laxity were associated with failure to return to baseline ROM and strength at early follow-up after anterior shoulder instability surgery. PMID- 29576340 TI - Superior glenoid inclination and rotator cuff tears. AB - BACKGROUND: The objectives of this study were to determine whether glenoid inclination (1) could be measured accurately on magnetic resonance imaging (MRI) using computed tomography (CT) as a gold standard, (2) could be measured reliably on MRI, and (3) whether it differed between patients with rotator cuff tears and age-matched controls without evidence of rotator cuff tears or glenohumeral osteoarthritis. METHODS: In this comparative retrospective radiographic study, we measured glenoid inclination on T1 coronal MRI corrected into the plane of the scapula. We determined accuracy by comparison with CT and inter-rater reliability. We compared glenoid inclination between patients with full-thickness rotator cuff tears and patients aged >50 years without evidence of a rotator cuff tear or glenohumeral arthritis. An a priori power analysis determined adequate power to detect a 2 degrees difference in glenoid inclination. RESULTS: (1) In a validation cohort of 37 patients with MRI and CT, the intraclass correlation coefficient was 0.877, with a mean difference of 0 degrees (95% confidence interval, -1 degrees to 1 degrees ). (2) For MRI inclination, the inter-rater intraclass correlation coefficient was 0.911. (3) Superior glenoid inclination was 2 degrees higher (range, 1 degrees -4 degrees , P < .001) in the rotator cuff tear group of 192 patients than in the control cohort of 107 patients. CONCLUSIONS: Glenoid inclination can be accurately and reliably measured on MRI. Although superior glenoid inclination is statistically greater in those with rotator cuff tears than in patients of similar age without rotator cuff tears or glenohumeral arthritis, the difference is likely below clinical significance. PMID- 29576341 TI - Fertility rescue and ovarian follicle growth promotion by bone marrow stem cell infusion. AB - OBJECTIVE: To assess if infusion of human bone marrow-derived stem cells (BMDSCs) could promote follicle development in patients with impaired ovarian functions. DESIGN: Experimental design. SETTING: University research laboratories. ANIMAL(S): Immunodeficient NOD/SCID female mice. INTERVENTION(S): Human BMDSCs were injected into mice with chemotherapy-induced ovarian damage and into immunodeficient mice xenografted with human cortex from poor-responder patients (PRs). MAIN OUTCOME MEASURE(S): Follicle development, ovulation, and offspring. Apoptosis, proliferation, and vascularization were evaluated in mouse and human ovarian stroma. RESULT(S): Fertility rescue and spontaneous pregnancies were achieved in mice ovaries mimicking PRs and ovarian insufficiency, induced by chemotherapy, after BMDSC infusion. Furthermore, BMDSC treatment resulted in production of higher numbers of preovulatory follicles, metaphase II oocytes, 2 cell embryos, and healthy pups. Stem cells promoted ovarian vascularization and cell proliferation, along with reduced apoptosis. In xenografted human ovarian tissues from PRs, infusion of BMDSCs and their CD133+ fraction led to their engraftment close to follicles, resulting in promotion of follicular growth, increases in E2 secretion, and enhanced local vascularization. CONCLUSION(S): Our results raised the possibility that promoting ovarian angiogenesis by BMDSC infusion could be an alternative approach to improve follicular development in women with impaired ovarian function. CLINICAL TRIAL REGISTRATION NUMBER: NCT02240342. PMID- 29576342 TI - RETRACTED: Letter to the editor "[Toxicology (2017) 159 -159]. PMID- 29576343 TI - Chemical burn assaults: Is the media coverage representative? PMID- 29576344 TI - Genital burns in the United States: Disproportionate prevalence in the pediatric population. AB - INTRODUCTION AND OBJECTIVES: To describe the epidemiology of genital burns in the U.S. and investigate the underlying etiology. METHODS: The National Electronic Injury Surveillance System database was queried for individuals who sustained genital burns from 2000 to 2016. We collected data on age, gender, injury diagnosis, disposition, and causative agents. Multivariate analysis was performed to determine predictors of hospitalization. RESULTS: We estimate 17,026 (95% CI 16,649-17,404) cases of genital burns presented to emergency departments nationally. Genital burns occurred more in males than females (12,295 vs 4,731). Scalding (57.9%) was the most common mechanism of injury and hot water (35.7%) the most common causative agent. Significant predictors of hospitalization on multivariate analysis were multi-surface (OR 4.4), scalding (OR 11.5) and thermal burns (OR 27.9). Children ages 0-2 had the highest prevalence of genital burns, and children ages 0-12 comprised 37.1% of the study. For children <5years of age, majority of the burns were caused by hot water in the bathroom. In age group 6 12, the most common causes of genital burns were cooking-related scalds due to hot foods and water. CONCLUSIONS: Children sustain genital burns at a higher rate than adults and many appear to have a preventable mechanism. Improved product design for safety and educating caregivers about potential hazardous situations are needed. PMID- 29576345 TI - A review of the validity of malnutrition screening tools used in older adults in community and healthcare settings - A MaNuEL study. AB - BACKGROUND: Older adults are at increased risk of malnutrition compared to their younger counterparts. Malnutrition screening should be conducted using a valid malnutrition screening tool. An aim of the Healthy Diet for a Healthy Life (HDHL) Joint Programming Initiative (JPI) 'Malnutrition in the Elderly Knowledge Hub' (MaNuEL) was to review the reported validity of existing malnutrition screening tools used in older adults. METHODS: A literature search was conducted to identify validation studies of malnutrition screening tools in older populations in community, rehabilitation, residential care and hospital settings. A database of screening tools was created containing information on how each tool was validated. RESULTS: Seventy-four articles containing 119 validation studies of 34 malnutrition screening tools used in older adults were identified across the settings. Twenty-three of these tools were designed for older adults. Sensitivity and specificity ranged from 6 to 100% and 12-100% respectively. Seventeen different reference standards were used in criterion validation studies. Acceptable reference standards were used in 68 studies; 38 compared the tool against the Mini Nutritional Assessment-Full Form (MNA-FF), 16 used clinical assessment by a nutrition-trained professional and 14 used the Subjective Global Assessment (SGA). Twenty-five studies used inappropriate reference standards. Predictive validity was measured in 14 studies and was weak across all settings. CONCLUSIONS: Validation results differed significantly between tools, and also between studies using the same tool in different settings. Many studies have not been appropriately conducted, leaving the true validity of some tools unclear. Certain tools appear to be more valid for use in specific settings. PMID- 29576346 TI - Patients' experiences with home parenteral nutrition: A grounded theory study. AB - BACKGROUND & AIMS: Parenteral nutrition (PN) provides nourishment and hydration as an intravenous infusion to patients with intestinal failure (IF). The aim of the study is to generate theory that explains the experiences of adult patients living with home parenteral nutrition (HPN) and complex medication regimens. METHODS: A grounded theory methodology was used to explore the experiences of twelve patients receiving HPN. A semi-structured interview was conducted and recorded in each participant's home setting. Each interview was transcribed verbatim. The simultaneous process of data collection and analysis was followed reflecting the principles of the constant comparative approach. RESULTS: A total of 15 patients gave written consent, with 12 of them agreeing to be interviewed. All the participants had previously undergone surgery as a result of chronic ill health or sudden illness. Analysis revealed two core categories: stoma and HPN, and these were supported by the subcategories: maintaining stoma output, access to toilets, managing dietary changes, maintaining the HPN infusion routine, access to technical help to set up an HPN infusion, mobility with HPN equipment and general health changes. The strategy of living with loss was demonstrated by all the participants, and this was supported by the action strategies of maintaining daily activities and social interactions. CONCLUSIONS: This study generates new understanding and insight into the views and experiences of patients receiving HPN in the UK. The findings from these participants have been shown to resonate with the Kubler-Ross Model [1] of the five stages of grief. The theory of living with loss was generated by the use of a grounded theory methodology. This small scale exploratory study reveals opportunities for improvements in practice to be considered by the nutrition support team (NST) and other healthcare professionals involved in the patient's hospital stay prior to discharge on HPN. PMID- 29576347 TI - Intestinal pathogen clearance in children with severe acute malnutrition is unrelated to inpatient morbidity. AB - BACKGROUND & AIMS: Children with Severe Acute Malnutrition (SAM) often suffer from diarrhea, which is associated with increased mortality. The contribution of intestinal bacteria, parasites and viruses to morbidity such as diarrhea in SAM remains poorly understood. To evaluate their association with clinical outcomes, we detected stool pathogens in children with SAM at hospital admission and after clinical stabilization prior to discharge. METHODS: 15 intestinal pathogens, fecal calprotectin and C-reactive protein (CRP) were determined at admission and after clinical stabilization in children aged 8-59 months (n = 47) hospitalized in Malawi for complicated SAM. Differences in fecal pathogens, intestinal and systemic inflammation, and clinical outcomes between time points were evaluated using the Wilcoxon Signed-Rank test or Wilcoxon rank-sum test. RESULTS: On admission pathogens were present in nearly all children and after clinical stabilization many were cleared with only 55% of children still harboring a pathogen (89% vs. 55%, p = 0.001). Nosocomial infections were infrequent. The pathogens Giardia lamblia and Shigella spp. were most likely to persist. After clinical stabilization, fecal calprotectin was higher in children harboring a pathogen (median (IQR): 383 mg/kg (903-149 mg/kg) vs 140 mg/kg (300-71 mg/kg), p = 0.03). CRP did not correlate with fecal calprotectin levels nor was it associated with pathogen detection. Presence of stool pathogens was not associated with clinical outcomes such as diarrhea. CONCLUSIONS: Fecal pathogens were very common and cleared in most children with complicated SAM treated with antibiotics. The presence of stool pathogens after stabilization was associated with increased intestinal inflammation but not with clinical outcomes. (http://www.isrctn.com/ISRCTN13916953). PMID- 29576348 TI - Value of sarcopenia assessed by computed tomography for the prediction of postoperative morbidity following oncological colorectal resection: A comparison with the malnutrition screening tool. AB - BACKGROUND: Computed tomography (CT) can be used for accurate estimation of whole body muscle mass and muscle density and for detection of sarcopenia. The goal of this study was to evaluate the additional value of CT measured sarcopenia and muscle attenuation alongside the Malnutrition Universal Screening Tool (MUST) for the prediction of post-operative morbidity after oncological colorectal resection, whilst correcting for known risk factors. METHODS: A prospective cohort study of 80 patients undergoing elective colorectal surgery in the Netherlands. Patients were screened for nutritional risk upon admission using the MUST. Additionally, preoperative CT scans were used to determine skeletal muscle mass for the detection of sarcopenia and muscle attenuation. Univariate and multivariable analyses were performed to evaluate associations between the MUST, muscle attenuation and sarcopenia on the one hand and post-operative complications measured by the Clavien-Dindo score on the other hand. RESULTS: American Society of Anesthesiology-classification (ASA) >=3, age >=70, MUST >=2 and lower than median muscle attenuation were significantly associated with a higher risk for postoperative complications (Clavien-Dindo score >=2) (p <= 0.05), whereas sarcopenia was not (p = 0.59). Multivariate analyses showed that only MUST >=2 remained significantly associated with postoperative complications when corrected for age (p = 0.03, OR 5.8, 95%CI 1.1-29.6), but not when corrected for age >=70 and ASA >=3. Muscle attenuation and sarcopenia were not significantly associated with postoperative complications. CONCLUSION: Our results suggest that using CT measured sarcopenia may have only little additional value over the MUST for the prediction of increased short-term post-operative morbidity after oncological colorectal surgery. It also underlines the importance of currently implemented easy-to-use nutritional screening tools (MUST) and raises the question of the evaluation of muscle quality versus quantity in body composition imaging. However, further research is needed to investigate the role of sarcopenia for predicting outcome after colorectal surgery, and investigate the role of muscle attenuation measurements for the prediction of muscle function. CATEGORY OF SUBMISSION: observational study. PMID- 29576349 TI - Use of both quantitative and qualitative methods to improve assessment of resting energy expenditure equation performance in hospitalized adults. AB - OBJECTIVE: To introduce the use of qualitative assessment in energy expenditure (EE) equation research to improve the understanding of performance of the equations in the clinical setting. PATIENTS AND METHODS: Hospitalized individuals who had an indirect calorimetry (IC) measurement during their hospital stay from 2010 to 2012 were included in the study (n = 59). An additional 1000 patients hospitalized during this time were used to limit the IC cohort to a more "clinically relevant" BMI range (n = 46). The following estimation equations were assessed: Harris-Benedict, 25 kcal/kg using actual body weight, Mifflin St. Jeor, Ireton-Jones, Penn State, and Owen. Bland-Altman plots with Loess curves were generated to compare estimated basal caloric needs between EE equations and IC values. RESULTS: This study found a large amount of variability with all EE equations. As the mean calorie level increased, the Harris Benedict, Mifflin St. Jeor, Penn State, and Owen equations all tended to increasingly under-predict caloric need. CONCLUSION: In a research setting a qualitative assessment of EE equations can provide a more comprehensive understanding of equation performance by complementing traditional quantitative methods. The addition of a Loess curve to the Bland-Altman plot further enhances qualitative assessment. PMID- 29576350 TI - Differential effects of leucine and leucine-enriched whey protein on skeletal muscle protein synthesis in aged mice. AB - BACKGROUND & AIMS: It has been suggested that anabolic resistance, or a blunted protein synthetic response to anabolic stimuli, contributes to the failure of muscle mass maintenance in older adults. The amino acid leucine is one of the most prominent food-related anabolic stimuli. However, data on muscle protein synthesis (MPS) after administration of a single bolus of leucine in aged populations is lacking and long-term single leucine supplementation has not been shown to increase muscle mass. This study aimed to determine the MPS response to the administration of a single bolus of leucine or to leucine combined with whey protein, in aged mice. METHODS: Overnight fasted C57/BL6RJ mice at 25-mo of age received an oral gavage with leucine or whey-protein enriched with leucine (0.75 g/kg bodyweight total leucine in both) or 0.5 mL water (fasted control). Subsequently, mice were s.c. injected with puromycin (0.04 MUmol/g bw at t = 30, 45 or 60 min) and were sacrificed 30 min thereafter. Amino acid concentrations were determined in plasma and right muscle tibialis anterior (TA). Left TA was used to analyse MPS by SUnSET method and phosphorylation rate of Akt, 4E-BP1 and p70S6k by western blot. RESULTS: In aged mice, leucine administration failed to increase MPS, despite a 6-fold increase in plasma leucine and elevated muscle free leucine levels (P < 0.05). In contrast, leucine-enriched whey protein significantly stimulated MPS in aged mice at 60 min after gavage (P < 0.05). Muscle free EAA, NEAA and the phosphorylation rate of Akt, 4E-BP1 and p70S6k increased significantly (P < 0.05), only after administration of leucine-enriched whey protein. CONCLUSIONS: MPS is stimulated in aged mice by leucine-enriched whey protein but not by leucine administration only. Administration of other amino acids may be required for leucine administration to stimulate muscle protein synthesis in aged mice. PMID- 29576351 TI - Transthyretin levels: Potential biomarker for monitoring nutritional support efficacy and clinical complications risk in patients receiving parenteral nutrition. AB - : Nutritional support is an effective strategy to restore or maintain nutritional status, to reduce clinical complications, hospitalization period and the morbidity/mortality risk of hospitalized patients. So, a good marker is important to evaluate the nutritional support. OBJECTIVES: This study aims to evaluate the evolution of transthyretin levels in patients receiving parenteral nutrition (PN) during 14 days. DESIGN & METHODS: Longitudinal study of 88 hospitalized patients. The assessments and samples were taken during the first 72 h (T0), on the 7th day (T7) and 14th day (T14) of PN. This study was approved by the Ethics Committee of the School of Medical Sciences at UNICAMP (No 538/2011). RESULTS: The C-reactive protein (CRP) levels were high and albumin and transthyretin levels were low at baseline. From T0 to T14, only transthyretin increased (p = 0.03). According to the receiver operation characteristic (ROC) curve, we found that the transthyretin had some improvement when the CRP levels were less than 10.4 mg/dl (T7). According to the CRP/albumin ratio, all patients classified as without risk for complications were discharged from the hospital. In addition, we observed that patients with transthyretin reduction had a concomitant higher risk for complications according to their ratio CRP/albumin (p = 0.03). CONCLUSIONS: CRP/albumin ratio was associated with the evolution of transthyretin levels. Transthyretin values showed significant improvement in the 14 days of PN. Especially, less inflamed patients (ie CRP less than 10.4 mg/dl) improved their transthyretin levels. So, CRP value at day 7 that predicts the transthyretin and transthyretin is a good biomarker for classification of nutritional support and clinical complications risk in patients receiving PN. PMID- 29576352 TI - Impact of intermittent fasting on the lipid profile: Assessment associated with diet and weight loss. AB - Intermittent fasting, whose proposed benefits include the improvement of lipid profile and the body weight loss, has gained considerable scientific and popular repercussion. This review aimed to consolidate studies that analyzed the lipid profile in humans before and after intermittent fasting period through a detailed review; and to propose the physiological mechanism, considering the diet and the body weight loss. Normocaloric and hypocaloric intermittent fasting may be a dietary method to aid in the improvement of the lipid profile in healthy, obese and dyslipidemic men and women by reducing total cholesterol, LDL, triglycerides and increasing HDL levels. However, the majority of studies that analyze the intermittent fasting impacts on the lipid profile and body weight loss are observational based on Ramadan fasting, which lacks large sample and detailed information about diet. Randomized clinical trials with a larger sample size are needed to evaluate the IF effects mainly in patients with dyslipidemia. PMID- 29576353 TI - Improving nutrition care and intake for older hospital patients through system level dietary and mealtime interventions. AB - BACKGROUND & AIMS: Interventions such as oral nutritional supplements (ONS), fortified meals and mid-meals, feeding assistants and Protected Mealtimes have shown some impact on nutritional intake in research studies, but embedding them in practise remains challenging. This study monitored nutritional intake of older medical inpatients as dietary and mealtime interventions were progressively implemented into routine practise. METHODS: Series of three prospectively evaluated patient cohorts allowed comparison of nutritional intake of 320 consented medical inpatients aged 65 + years: cohort 1 (2007-8), cohort 2 (2009) and cohort 3 (2013-14) as nutrition care interventions were progressively introduced and embedded. Interventions focused on 'assisted mealtimes', fortified meals and mid-meals, and ONS. Energy and protein intake were calculated from visual plate waste of individual meal and mid-meal components on day 5 of admission. Nutrition care processes were evaluated by mealtime audits of diet type, assistance and interruptions on the same day. One-way ANOVA and chi square tests were used for comparison between cohorts. RESULTS: Significant, progressive improvements in energy and protein intake were seen between cohorts (energy: cohort 1: 5073 kJ/d; cohort 2: 5403 kJ/d; cohort 3: 5989 kJ/d, p = 0.04; protein: cohort 1: 48 g/d, cohort 2: 50 g/d, cohort 3: 57 g/d, p = 0.02). Greater use of fortified meals and mid-meals and sustained improvements in mealtime assistance likely contributed to these improvements. CONCLUSIONS: Multi-faceted system-level approach to nutrition care, including changes to dietary and mealtime care processes, was associated with measureable and sustained improvements in nutritional intake of older inpatients over a seven year period. PMID- 29576354 TI - Aged garlic extract supplementation modifies inflammation and immunity of adults with obesity: A randomized, double-blind, placebo-controlled clinical trial. AB - BACKGROUND: Obesity is a serious global health issue and often results in low grade systemic inflammation, increasing the risk for several chronic diseases. If obesity-induced inflammation could be reduced, fewer complications and co morbidities might occur. OBJECTIVE: To investigate whether daily supplementation with aged garlic extract (AGE) could reduce chronic inflammation and improve immune function in adults with obesity. METHODS: Fifty-one healthy adults with obesity (mean age 45.6 +/- 1.6 years, mean BMI 36.1 +/- 0.9 kg/m2) were recruited to participate in a parallel, double-blind, placebo-controlled, randomized study. After being matched by BMI, participants were randomized into the AGE supplementation or placebo group. Participants were asked to take a divided daily dose of 3.6 g AGE or placebo, with food for 6 weeks. Blood lipid and inflammatory markers were assessed at baseline and after 6 weeks of supplementation. Additionally, peripheral blood mononuclear cells (PBMC) were isolated from whole blood and used to detect changes in immune cell populations and levels of cytokine secretion. A one-way ANCOVA was performed to evaluate differences between the two groups, controlling for respective baseline values. RESULTS: At the end of study, serum IL-6 (p = 0.04) and TNF-alpha (p = 0.05) of participants consuming AGE were significantly lower than those consuming the placebo capsules. PBMC flow cytometry results showed that participants from the AGE group had a higher proportion of gammadelta-T cells (p = 0.03) and a lower proportion of NKT cells (p = 0.02) in the total population of lymphocytes. There was no difference in percentage of NK cells between the two groups. A significant difference in blood LDL concentration was also observed (p = 0.05). Total cholesterol and non HDL cholesterol tended to differ between participants from the AGE group and those from the placebo group, although values did not achieve statistical significance. CONCLUSION: Six weeks of AGE consumption modulated immune cell distribution, prevented the increase of serum TNF-alpha and IL-6 concentrations and reduced blood LDL concentration in adults with obesity. AGE, taken consistently, may be beneficial in preventing the development of chronic diseases associated with low-grade inflammation in adults with obesity.

PMID- 29576355 TI - Nutrition therapy for critically ill patients across the Asia-Pacific and Middle East regions: A consensus statement. AB - BACKGROUND & AIMS: Guidance on managing the nutritional requirements of critically ill patients in the intensive care unit (ICU) has been issued by several international bodies. While these guidelines are consulted in ICUs across the Asia-Pacific and Middle East regions, there is little guidance available that is tailored to the unique healthcare environments and demographics across these regions. Furthermore, the lack of consistent data from randomized controlled clinical trials, reliance on expert consensus, and differing recommendations in international guidelines necessitate further expert guidance on regional best practice when providing nutrition therapy for critically ill patients in ICUs in Asia-Pacific and the Middle East. METHODS: The Asia-Pacific and Middle East Working Group on Nutrition in the ICU has identified major areas of uncertainty in clinical practice for healthcare professionals providing nutrition therapy in Asia-Pacific and the Middle East and developed a series of consensus statements to guide nutrition therapy in the ICU in these regions. RESULTS: Accordingly, consensus statements have been provided on nutrition risk assessment and parenteral and enteral feeding strategies in the ICU, monitoring adequacy of, and tolerance to, nutrition in the ICU and institutional processes for nutrition therapy in the ICU. Furthermore, the Working Group has noted areas requiring additional research, including the most appropriate use of hypocaloric feeding in the ICU. CONCLUSIONS: The objective of the Working Group in formulating these statements is to guide healthcare professionals in practicing appropriate clinical nutrition in the ICU, with a focus on improving quality of care, which will translate into improved patient outcomes. PMID- 29576356 TI - Thickness of the adductor pollicis muscle: Accuracy in predicting malnutrition and length of intensive care unit stay in critically ill surgical patients: Thickness of the adductor pollicis muscle in surgical critically patients. AB - BACKGROUNDS & AIMS: new techniques for assessment of nutritional status of critically ill and surgical patients have been investigated to overcome inherent limitations of conventional method. The current study aimed to evaluate the ability of thickness of the adductor pollicis muscle (TAPM) in detecting malnutrition and predicting morbidity and mortality in critically ill surgical patients. METHODS: cohort study of adult patients, assessed within the 48 h of admission to the surgical intensive care unit (ICU) of a public hospital. TAPM measurements of the non-dominant hand were performed with patients lying supine. TAPM values lower than the 5th percentile for age and sex were adopted to identify malnutrition. Patients were followed up until discharge for measurement of the following parameters: length of ICU stay, time on mechanical ventilation, length of hospital stay, and hospital mortality. RESULTS: fifty-nine surgical ICU patients, with mean age of 60.0 +/- 17.4 years were included in the current study. There was a positive, weak-to-moderate correlation between TAPM and anthropometric indicators (r = 0.338 to r = 0.579; p < 0.01). The ability of TAPM in identifying patients with malnutrition (diagnosed by global subjective assessment) was assessed by ROC curve analysis, and an area under the ROC curve of 0.611 (95%CI: 0.459-0.762; p = 0.151) was found. TAPM < p5 increased the risk of ICU length of stay >3 days (RR = 2.92; 95%CI 1.09-7.81; p = 0.032). Relative frequencies of malnourished and well-nourished patients according to TAPM were not different between survivors and non-survivors (p = 0.814). CONCLUSION: TAPM showed unsatisfactory accuracy in predicting malnutrition. Although TAPM was not a good mortality predictor, reduced TAPM (< p5) values increased the risk of a prolonged ICU stay (>3 days). PMID- 29576357 TI - Longitudinal changes in phase angle by bioimpedance in intensive care patients differ between survivors and non-survivors. AB - BACKGROUND & AIMS: Intensive care (ICU) patients suffer from metabolic stress, creating a catabolic state which might disturb nutritional status and body composition. Alterations in body fluid compartments by disease or massive volume resuscitation could invalidate bioimpedance hydrometry. Still bioimpedance might give other information. METHODS: 52 ICU patients (35 male, 17 female, mean age 66 years), BMI 29,2 were assessed by bioimpedance spectroscopy. Phase angle (PhA) at 50 kHz was assessed. RESULTS: On first assessment PhA was 3.7 +/- 1.0 degrees . In 26 patients reassessed after median 5 days PhA was not significantly changed, although R 50 kHz and Xc 50 kHz both increased (p = 0.047), indicating diminishing overhydration. Body weight and body cell mass decreased by 1.8 +/- 5.7 and 2.8 +/- 7.5 kg (p = 0.13). Fat free mass and extracellular water decreased 4.5 +/- 8.9 kg (p = 0.032) and 1.5 +/- 3.5 kg (p = 0.031), while CRP decreased 63 mg/l (p = 0.002). In 17 survivors PhA increased 0.62 +/- 1.24 degrees (NS), while in 9 non-survivors PhA decreased 0.24 +/- 0.82 degrees (p = 0.06), with 0.86 degrees difference (p = 0.049) between groups. CONCLUSION: Phase angle by bioimpedance is very low in ICU patients and positive changes in PhA seems to reflect more favorable outcome. Bioimpedance by Body Scout appears unsuitable for the assessment of fat free mass or overhydration in ICU patients. PMID- 29576358 TI - A lecithin phosphatidylserine and phosphatidic acid complex (PAS) reduces symptoms of the premenstrual syndrome (PMS): Results of a randomized, placebo controlled, double-blind clinical trial. AB - BACKGROUND & AIMS: Many women experience emotional and physical symptoms around the time of ovulation and more so before menstruation interfering with their daily normal life also known as premenstrual syndrome (PMS). Recent observational data suggest that supplementation with Lipogen's phosphatidylserine (PS) and phosphatidic acid (PA) complex (PAS) alleviates these PMS symptoms. The aim of this study was to confirm these observations on the effects of PAS on PMS symptom severity within a controlled clinical trial setting. METHODS: Forty women aged 18 45 years with a diagnosis of PMS were assigned to either take PAS (containing 400 mg PS & 400 mg PA per day) or a matching placebo. The study comprised 5 on-site visits including 1 baseline menstrual cycle followed by 3 treatment cycles. Treatment intake was controlled for by using an electronic device, the Medication Event Monitoring System (MEMS(r)). Primary outcome of the study was the PMS symptoms severity as assessed by using the Daily Record of Severity of Problems (DRSP). Further, SIPS questionnaire (a German version of the Premenstrual Symptoms Screening Tool (PSST)), salivary hormone levels (cortisol awakening response (CAR) and evening cortisol levels) as well as serum levels (cortisol, estradiol, progesterone and corticosteroid binding globulin (CBG)) were assessed. RESULTS: PMS symptoms as assessed by the DRSP Total score showed a significantly better improvement (p = 0.001) over a 3 cycles PAS intake as compared to placebo. In addition, PAS treated women reported a greater improvement in physical (p = 0.002) and depressive symptoms (p = 0.068). They also reported a lower reduction of productivity (p = 0.052) and a stronger decrease in interference with relationships with others (p = 0.099) compared to the placebo group. No other DRSP scale or item showed significant results. Likewise, the reduction in the number of subjects fulfilling PMS or premenstrual dysphoric disorder (PMDD) criteria as classified by the SIPS did not differ between the PAS and the placebo group. For the biomarkers, the salivary cortisol percentage increase of the CAR was significantly less pronounced in the follicular phase of cycle 4 than in the follicular phase of cycle 1 for subjects taking PAS when compared to subjects taking placebo (p = 0.018). Furthermore, the change of serum cortisol levels between visit 1 and visit 5 differed significantly between groups (p = 0.043). While serum cortisol levels of PAS treated females slightly decreased between visit 1 and visit 5, cortisol levels of females treated with placebo increased. For all other biomarkers, no treatment effects were observed over the 4 cycles study period. Overall, this study confirms that a daily intake of PAS, containing 400 mg PS and 400 mg PA, can be considered as safe. CONCLUSIONS: Results substantiate the efficacy of PAS in reducing symptoms of PMS. In view of the recent inclusion of severe PMS symptoms (PMDD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the positive results of this clinical study merits consideration of developing the PAS complex as a botanical drug for treatment of PMDD. CLINICAL TRIAL REGISTRATION: The study is registered at Deutsches Register Klinischer Studien with the registration number DRKS00009005. PMID- 29576359 TI - Correlation of symptoms to serum vitamin D levels? AB - BACKGROUND AND OBJECTIVE: Recent studies have shown that vitamin D plays an important role in many disease processes. However, data is lacking which correlates the common symptoms attributed with vitamin D levels. This study was undertaken to find the correlation of symptoms and Vitamin D levels among ethnic Saudi Arabian population. METHODS: A structured questionnaire was made and translated in the Arabic language, which included, age, weight and height, ethnicity and marital status. Patients who were visiting orthopaedic clinics for the first time were included after a detailed history, which ruled out any associated metabolic conditions. Patient's biometric data and the answering of the questionnaire were conducted by one of the senior members of the research group. The symptoms which were included in the questionnaire were fatigue, muscle cramps, joint and back pain, blood sugar levels, recurrent infections, hair loss, mood swings, weight gain, irritable bowel, fractures and history of malignancy. All the scores were graded between 1 and 9 (mildest 1 and severe 9) and only for fracture and malignancy it was yes/no answer. A score of <=4 was accepted as no impact of the vitamin D levels on symptoms and answer of >=5 was accepted as impact on the symptoms. Residents whose mother tongue was Arabic conducted all interviews. Blood was collected for 25 OHD levels, calcium and parathyroid hormone levels. Deficiency of vitamin D was defined as <=20 ng/ml, insufficiency 21-29 ng/ml and normal level >=30 ng/ml. The data was entered in the data base and analyzed using SPSS Inc Version 20. RESULTS: Two hundred one patients completed the questionnaire but for final analysis the data of 187 was available for analysis as in 14 patients some of the data was missing. All were females and the average age was 55.9 +/- 12.4 years, weight 78.9 +/- 14.2 kg and height was 1.56 +/- 7.01 m. The mean calcium level was 9.12 +/- 0.33 mg/dl and, parathyroid hormone was 8.1 +/- 6.06 pc/ml. The average 25 hydroxy vitamin D3 (25OHD) level was 21.8 +/- 10.22 ng/ml. Forty-four (23.5%) of women had a normal vitamin D level, 51 (27.27%) had insufficiency and 92 (49.19%) had deficiency. Patients who complained of muscle cramps had 25OHD level of 18.86 +/- 8.73 compared to patients who had no complains of cramps, 23.45 +/- 9.2 ng/ml (p < 0.001) and symptom severity score (SSC) p value of p < 0.000. The results were similar for fatigue, Back pain, hair loss, mood swings and weight gain of P < 0.04, p < 0.07, p < 0.05, <0.03 and p < 0.09 for vitamin D levels and p < 0.001 for SSS. Forty eight (25.6%) had a previous fracture in their history. CONCLUSIONS: This study shows that many symptoms, which have been attributed to low vitamin D levels, are not true. Muscle Cramps, fatigue, mood swings, hair loss, back pain and weight gains appears to be more common in patients with low 25OHD levels. PMID- 29576360 TI - The impact of Home Parenteral Nutrition on the lives of adults with Type 3 Intestinal Failure. AB - BACKGROUND & AIMS: Several studies have been published reporting on the impact of Home Parenteral Nutrition (HPN) on the lives of people with Type 3 Intestinal Failure. These studies focused on symptoms and functional limitations resulting from the treatment. The aim of this study was to determine how dependence on HPN affects individuals' ability to fulfil their human needs. METHODS: Unstructured qualitative interviews were conducted with people dependent on HPN, who were asked to explain how their lives were affected by the treatment. Theoretical thematic analysis was conducted on the interview transcripts to identify statements describing aspects of human needs that were left unfulfilled. Care was taken to separate the impact of HPN from that of the underlying disease. RESULTS: Interviews were conducted with 30 patients (53% female; mean age, 55.9 (range 35 76) years). Most of the sample (87%) had short bowel syndrome. Major aspects of need affected by HPN were related to: autonomy, cognition, relationships, role fulfilment, socialisation, appearance and self-esteem, appetite and perceived vulnerability. CONCLUSIONS: The study illustrates how patients' lives are affected by HPN. Statements generated from this qualitative study were used to produce the Parenteral Nutrition Impact Questionnaire (PNIQ), a patient-centric measure of quality of life specific to people using HPN. PMID- 29576361 TI - Can energy intake alter clinical and hospital outcomes in PICU? AB - BACKGROUND & AIMS: Energy is essential for the treatment and recovery of children admitted to Pediatric Intensive Care Units (PICU). There are significant immediate and long-term health consequences of both under- and over-feeding in this population. Energy requirements of critically ill children vary depending on age, nutritional status, sepsis, fever, pharmacotherapy, and duration and stage of critical illness. This study aimed to determine the incidence of over- and under-feeding and to compare hospital outcomes between these feeding categories. Secondary outcomes were collected to describe the association between feeding categories and biochemistries (serum lactate, triglycerides, C-reactive protein). METHODS: An ethics approved retrospective study of children admitted to PICU was performed. All intubated patients admitted to PICU (2008-2013) were included, except those in which an IC test was not feasible. Data collection included demographics, the primary outcome variable reported as under feeding (<90%MREE), appropriate (MREE +/-10%) or overfeeding (>110% MREE) determined through comparison of measured resting energy expenditure (MREE) using indirect calorimetry (IC) to actual energy intake based on predicted basal metabolic rate (PBMR) and clinical outcomes mechanical ventilation and PICU length of stay (LOS). Data were analysed with descriptive methods, ANOVA and linear regression models. RESULTS: A total of 139 patients aged 10 (range 0.03-204) months were included. Sixty (43%) were female and 77 (55%) were admitted after a surgical procedure. A total of 210 IC tests were conducted showing a statistically significant difference between MREE measurements and PBMR (p = 0.019). Of the 210 measurements, only 26 measures (12.4%) demonstrated appropriate feeding, while 72 (34.3) were underfed and 112 (53.3%) were overfed. Children who were overfed had significantly longer PICU LOS (median 45.5, IQR 47.8 days) compared to those children in the appropriately fed (median 21.0, IQR 54.5 days), and underfed groups (median 16.5, IQR 21.3 days). There was a mean difference between the over and under feeding category and ventilation days after adjusting for age and PRISM score (p = 0.026), suggesting decreased mechanical ventilation days for underfed. Children who were underfed had significantly higher CRP (median 75.5, IQR 152.8 mg/L) compared to those children in the appropriately fed (median 57.8, IQR 90.9 mg/L) and overfed groups (median 22.4, IQR 56.2 mg/L). CONCLUSIONS: This retrospective study confirms that estimations of energy expenditure in critically ill children are inaccurate leading to unintended under and overfeeding. Importantly under feeding seems to be associated with fewer mechanical ventilation days and PICU LOS. Further research is required to elucidate the role of optimal nutrition in altering clinical variables in this population. PMID- 29576362 TI - The impact of body mass index on post resuscitation survival after cardiac arrest: A meta-analysis. AB - BACKGROUND: Observational studies examining the association between body mass index (BMI) and the outcome of cardiac arrest (CA) shows controversial results. METHODS: We reviewed literature for studies assessing the impact of BMI on survival and neurological outcome following CA. Eligible studies were subsequently meta-analyzed and pooled odds ratios and their corresponding 95% confidence intervals for post CA survival and neurological status were derived. RESULTS: A total of 7 studies with 24,651 patients were evaluable for this meta analysis. The studies were also categorized by location of the CA and the use of therapeutic hypothermia. Our results suggested that BMI between 25 and 29.9 kgr/m2 had a favorable impact on survival after CA (OR = 1.172, 95% CI, 1.109 1.236) in comparison to normal weight subjects. Likewise, overweight patients presented increased odds for a favorable neurological outcome after CA (OR = 1.112, 95% CI, 1.020-1.213). On the contrary, underweight subjects presented decreased odds of surviving after CA as compared to normal BMI subjects (OR = 0.781, 95% CI, 0.652-0.935). Finally, BMI >30 kgr/m2 was not associated with improved survival or neurological outcome as compared to BMI 18.5-24.9 kgr/m2. CONCLUSIONS: Overweight patients have a favorable prognosis after CA in terms of both survival and neurological outcome. This effect was amplified when the analysis is restricted in in-hospital cardiac arrest and in patients non-treated with therapeutic hypothermia. PMID- 29576363 TI - Hyperlipidemia secondary to acitretin therapy for lamellar ichthyosis associated with a NIPAL4 mutation improves on a plant-based diet and relapses on a standard Western diet. AB - Oral retinoids are commonly prescribed for many dermatological conditions and may induce hyperlipidemia. We document the case of a 35-year-old man taking acitretin for congenital lamellar ichthyosis associated with a homozygous deleterious mutation in NIPAL4 who developed retinoid-induced hyperlipidemia that responded dramatically to a whole-food plant-based (WFPB) diet. On presentation, his diet consisted of chicken, fish, low fat meats and dairy, grains, and some fruits and vegetables. He then adopted a WFPB diet without making changes to his medications. His serum lipid levels dropped and his exercise capacity improved. Five months later, after discontinuing the plant-based diet and returning to his baseline diet, his hyperlipidemia returned and persisted despite adjustments to his medications. After a year and a half, the patient again adopted a plant-based diet and his lipid levels fell sharply again. A WFPB diet helped improve and control serum lipid levels in a patient with retinoid-induced hyperlipidemia. Future interventions should focus on ways to help patients successfully adopt and maintain a WFPB diet, as increased adherence to a healthy lifestyle is associated with greater health benefits. PMID- 29576364 TI - Anthropometric and demographic predictors of handgrip strength and lean mass quality in hospitalized individuals. AB - BACKGROUND AND AIM: Low strength and/or lean mass quality are associated with higher hospitalization and mortality. The aim of this study was to evaluate the main demographic and anthropometric predictors of strength and lean mass quality in hospitalized patients. METHODS: We evaluated 136 patients (18-86 years) of both sexes, admitted in a public hospital. Waist circumference (WC) was measured using an inelastic tape, lean mass (LM) was assessed by bioimpedance, and handgrip strength (HGS) was performed using a dynamometer. Lean mass quality (HGS/LM) was also calculated. RESULTS: We noted that LM predicted 33.1% of HGS, whereas WC was not associated with HGS. Evaluating LM and WC in the same statistical model, WC (beta = -0.249, p = 0.001) increased the prediction of HGS by 4.7% when compared to LM alone. Accessing LM, WC, age, and sex in the same model an increase in the prediction of HGS by 7.3% was noted when compared to LM alone, but only LM and sex were significant. In addition, WC predicted the lean mass quality by 4% (beta = -0.205, p = 0.016) and when WC, sex, and age were placed in the same model; WC (beta = -0.172, p = 0.035) and sex (beta = 0.332, p < 0.001) explained the variations in lean mass quality by 15%. CONCLUSION: The main predictor of lower HGS was lower LM, whereas sex showed a low association. Furthermore, although a low association was found, higher abdominal obesity and sex predicted lower lean mass quality. PMID- 29576365 TI - Comparison of predictive equations of lean mass in young and postmenopausal women. AB - BACKGROUND AND AIM: The lean mass (LM) is a predictor of functional capacity, quality of life, and mortality. In this way, the LM should be measured by reliable methods. However, it presents high cost and generally predictive equations are used in clinical practice, but little is known which is the best predictive equation of LM in women. The purpose of the present study was to verify which predictive equation of LM correctly estimates the LM in young and postmenopausal women. METHODS: Eighty-one women aged 19-81 years were evaluated. Body weight, height, waist circumference, and skin folds (bicipital, tricipital, subscapular and suprailiac) were measured. The LM was evaluated by DXA and also estimated using the predictive equations of Hume I, Hume II, Salamat, Kulkarni I, and Kulkarni II. Bland-Altman analysis was performed to evaluate the over/underestimation of the LM by predictive equations. RESULTS: The equations of Salamat, Kulkarni II, Hume I and Kulkarni I overestimated the LM by 0.0 (7.0; 6.9) kg; 2.3 (7.5; -3.0) kg; 5.1 (9.0; 0.4) kg; and 9.7 (16.3, 3.1) kg, respectively; whereas Hume II equation underestimated the LM by -16.9 (-11.5; 22.2) kg. CONCLUSIONS: The equation that presented a better prediction of LM was Salamat. However, it should be used with caution in clinical practice since this equation showed elevated confidence intervals and limits of agreements, and can lead to significant errors for some individuals. PMID- 29576366 TI - Low caloric and protein intake is associated with mortality in patients with acute kidney injury. AB - BACKGROUND: Acute renal injury (AKI) interferes greatly with nutritional status, affecting the metabolism of all macronutrients and increased mortality rates in hospitalized patients. Our objective was to evaluate the association of nutritional parameters (albumin, cholesterol, caloric and protein intake and nitrogen balance (NB)) with mortality in patients with AKI. METHODS: This is a prospective observational study that evaluated 595 consecutive patients over the age of 18 years with AKI, requiring enteral or parenteral feeding. At the time of the patient's enrollment, demographic and laboratorial data, caloric and protein supply and NB were recorded on the first day of referral to the nephrologist. All patients were followed throughout the hospital stay and mortality rate was also recorded. RESULTS: The medium age of patients with AKI was 64 (54-75) years, 64.5% male, 62% admitted to intensive care unit (ICU), 52% on dialysis and the majority (48%) were at stage 3 by AKIN. Length of stay and hospital mortality were 18 (10-31) days and 46%, respectively. Superior age, AKI severity, lower body weight and body mass index (BMI), higher need for dialysis, ICU admission and shorter hospital stay were associated with higher mortality. At logistic regression, caloric (OR: 0.946; CI:95%: 0.901-0.994; p:0.029) and protein intake (OR: 0.947; CI:95%: 0.988-0.992; p = 0.028) and serum albumin (OR: 0.545; CI:95%: 0.401-0741; p < 0.001) were associated with hospital mortality. Cholesterol (OR: 0.995; CI:95%: 0.991-1.000; p = 0.052) was not associated with increased mortality in the adjusted analysis. Analysis of the receiver operating characteristic (ROC) curve showed that calorie intake < 12 kcal/kg (AUC: 0.745; CI:95%: 0.684-0.765; p < 0.001) and protein intake < 0.5 g/kg (AUC: 0.726; CI:95%: 0.686-0.767; p < 0.001) were predictors of hospital mortality, as well as a negative NB < -6.47 g N/day (AUC: 0.745; CI:95%: 0.704-0.786; p < 0.001). CONCLUSIONS: In conclusion, low caloric and protein intake, negative NB and low albumin value are conditions associated with higher hospital mortality in patients with AKI.

AB - BACKGROUND & AIMS: Magnesium may play an important role in cardio-metabolic abnormalities, including type 2 diabetes, but epidemiological evidence linking magnesium status to glucose metabolism is limited among Asians. We cross sectionally examined the association of dietary and serum magnesium with markers of glucose metabolism among Japanese subjects. METHODS: Subjects were 1796 workers, aged 18-78 years, who participated in a health survey. Dietary magnesium intake was assessed with a validated brief diet history questionnaire. Serum magnesium concentrations were measured using an enzymatic method. Multivariable linear regression models were used to estimate means of fasting insulin, fasting plasma glucose, homeostatic model assessment of insulin resistance (HOMA-IR), homeostatic model assessment of beta-cell function (HOMA-beta), and glycated hemoglobin (HbA1c), with adjustments made for potential confounding variables. RESULTS: Dietary magnesium was inversely associated with HOMA-IR (Ptrend = 0.01). Multivariable-adjusted means (95% confidence intervals) of HOMA-IR for the lowest to highest quartiles of dietary magnesium were 0.94 (0.89-0.99), 0.92 (0.88 0.97), 0.88 (0.83-0.92), and 0.86 (0.81-0.90). Serum magnesium concentrations were also inversely associated with HOMA-IR (Ptrend = 0.04) and HbA1c (Ptrend <0.01). Multivariable-adjusted means (95% confidence intervals) for the lowest to highest quartiles of serum magnesium were 0.94 (0.90-0.98), 0.87 (0.83-0.91), 0.90 (0.85-0.95), and 0.86 (0.81-0.92) for HOMA-IR and 5.41 (5.36-5.45), 5.33 (5.28-5.37), 5.30 (5.25-5.36), and 5.28 (5.22-5.35) for HbA1c. Excluding subjects with diabetes did not materially change the association between dietary magnesium and HOMA-IR (Ptrend <0.01), while it attenuated the association of serum magnesium with HOMA-IR (Ptrend = 0.27) and HbA1c (Ptrend = 0.15). CONCLUSIONS: The present findings suggest that lower dietary magnesium, but not serum magnesium, is associated with IR in apparently healthy adults.

AB - PURPOSE: Reliability of arm muscle thickness measurement using ultrasonography (USG) by operators of varied experience is unknown. Hence, we planned this study to determine the reliability of arm muscle thickness measured using USG by 5 observers with variable experience. MATERIALS AND METHOD: This was a cross sectional observational study which included critically ill patients with sepsis. Arm muscle thickness was measured in triplicate on Siemens ACUSON X300TM USG machine by each of 5 observers. Intra-class correlation coefficient (ICC) was computed to assess intra-observer and inter-observer variability of multiple observations. RESULTS: This study included 45 (30 - male) patients. Mean (+/-SD) age, APACHE and SAPS score of the participants were 54.95 (+/-15.97) years, 14.66 (+/-4.57) and 2.6 (+/-1.37), respectively. There were 135 observations by each observer. ICC (95%CI) for intra-observer reliability study for observer 1, 2, 3, 4, and 5 were 0.997 (0.995-0.998), 0.996 (0.993-0.998), 0.997 (0.996-0.998), 0.997 (0.994-0.998) and 0.998 (0.986-0.999), respectively. ICC (95%CI) for inter observer reliability study for 1st, 2nd and 3rd reading were 0.963 (0.943-0.977), 0.992 (0.988-0.995) and 0.992 (0.988-0.995), respectively. CONCLUSIONS: There was an excellent intra- and inter-observer agreement among 5 observers for measurement of arm muscle thickness using bedside USG among patients with sepsis. PMID- 29576370 TI - Small intestinal absorption in patients with chronic obstructive pulmonary disease complicated by cor pulmonale - A pilot study. AB - BACKGROUND: Cor pulmonale is a common complication to Chronic Obstructive Pulmonary Disease (COPD), and may result in increased pressure in the inferior caval vein and stasis of the liver. The chronic pulmonary hypertension may lead to stasis in the veins from the small intestine and thereby compromise absorption of nutrients. AIM: To investigate whether patients with pulmonary hypertension have reduced absorption capacity compared to COPD patients without cor pulmonale. METHODS: Absorption of d-xylose (25 g) and zinc (132 mg), administered as a single dose, was tested in 14 COPD patients, seven with and seven without cor pulmonale. The presence of cor pulmonale was determined by echocardiography. The concentration of d-xylose and zinc were measured in peripheral blood one, two and three hours after ingestion and used as markers of absorption. Furthermore, urine was collected for five hours to determine the amount of excreted d-xylose. RESULTS: No significant difference in absorption of d-xylose (p = 0.28) or zinc (p = 0.51) was found between the two groups. However, a trend towards a delay in d-xylose absorption, as assessed by time-to-peak concentration, was observed in patients with cor pulmonale (p = 0.08). There was no significant difference in the amount of excreted d-xylose in the urine between the groups (p = 0.52). No correlation was found between the tricuspid regurgitation gradient and the absorption of both test-markers (rs = 0.34 and rs = -0.25). Likewise, no correlations were found between the inferior caval pressure during the in- and expiration phases and the absorption of d-xylose (rs = -0.09 rs = 0.23) or zinc (rs = -0.39, rs = -0.39). CONCLUSION: We found no indications that small intestinal absorption is affected in a clinically relevant degree in patients with cor pulmonale. PMID- 29576369 TI - The effect of long-term weight-loss intervention strategies on the dynamics of pancreatic-fat and morphology: An MRI RCT study. AB - BACKGROUND & AIMS: The ability to mobilize pancreatic-fat and the meaning of decreased fat in the pancreas remain controversial. We followed the dynamics of pancreatic-fat and its morphology during various long weight-loss induced lifestyle-interventions. METHODS: In isolated workplace with monitored/provided lunch, we randomly assigned healthy persons with abdominal obesity or dyslipidemia for one of two 18-month equal-caloric diets: low-fat (LF) or Mediterranean/low-carbohydrate (Med/LC, with provided 1oz walnuts/day), with or without added moderate exercise (supervised gym membership). We used magnetic resonance-imaging to quantify pancreatic-fat and morphology. RESULTS: At baseline, 277 eligible participants (mean age = 48 years; 88% men; pancreatic-fat = 17.4 +/- 5.1%) had higher pancreatic-fat in men (17.7 +/- 4.9% vs 14.9 +/- 5.5% in women; p = 0.004). Following 18-month intervention (adherence = 86.3%) and moderate weight-loss (mean = -3.0 +/- 5.5 kg), pancreatic-fat decreased moderately but significantly (-0.26 +/- 2.18% units; p = 0.049). Med/LC diet induced a greater decrease in pancreatic-fat compared to LF (p = 0.043), and the combination of Med/LC diet + exercise exhibited the highest reduction (-0.69% units) as compared to LF diet without exercise (+0.12%units; p = 0.027 between groups). In multivariate regression models, after further adjusted for visceral adipose-tissue (DeltaVAT), pancreatic-fat loss associated with both decreases in pancreatic-morphology ratio (perimeter divided by area; beta = 0.361; p < 0.001) and superficial-subcutaneous adipose-tissue loss (beta = 0.242; p = 0.001), but not with changes in intrahepatic-fat (beta = -0.034; p = 0.638). Pancreatic-fat loss associated with increased intake of polyunsaturated-fat (beta = -0.137; p = 0.032), as with improved high-density lipoprotein-cholesterol (HDL; beta = 0.156; p = 0.023) and triglycerides/HDL ratio (beta = 0.162; p = 0.015), independently of DeltaVAT, but not with glycemic-control parameters (e.g. HbA1c, HOMA-IR and HOMA-beta; p > 0.2 for all). CONCLUSIONS: Pancreatic-fat loss is mainly associated with improved lipid, rather than glycemic profiles. Med/LC diet, mostly with exercise, may benefit pancreatic-fat loss. Pancreatic morphology could serve as a biomarker of pancreatic-fat state. (ClinicalTrials.gov identifier: NCT01530724). PMID- 29576371 TI - Evaluation of water balance in a population of older adults. A case control study. AB - Older adults are at risk for dehydration and its' potentially life-threatening consequences. Unrecognized dehydration can complicate chronic medical problems and increase morbidity. The objective of the study was to estimate water balance, intake and loss in elderly people living in Greece using the Water Balance Questionnaire (WBQ). WBQ was administered in winter to 108 independents (65 81yrs) (Group A), 94 independents (82-92yrs) (Group B) and 51 hospitalized (65 92yrs) (Group C). A database from previous study of 335 adults (18-65yrs) (Control Group) used for comparison. Mean estimates of water balance, intake and loss were, respectively, for Group A -749 +/- 1386 mL/day, 2571 +/- 739 mL/day and 3320 +/- 1216 mL/day, for Group B -38 +/- 933 mL/day, 2571 +/- 739 mL/day and 3320 +/- 1216 mL/day, for Group C 64 +/- 1399 mL/day, 2586 +/- 1071 mL/day and 2522 +/- 1048 mL/day and for Control Group -253 +/- 1495 mL/day, 2912 +/- 1025 mL/day and 3492 +/- 2099 mL/day. Significant differences were detected in water balance, intake and loss (p < 0.01). Water balance and water intake in Group A was the lowest. For Groups A, B, C and Control, contribution of solid foods to water intake was 36%, 29%, 32%, 25%, of drinking water was 32%, 48%, 45%, 47%, of beverages was 32%, 23%, 23% and 28% respectively. Significant differences observed in the contribution of drinking water and beverages (p < 0.01). Group A had lower water balance and water intake. Groups B and C had lower water intake from beverages. PMID- 29576372 TI - A novel composite adaptive flap controller design by a high-efficient modified differential evolution identification approach. AB - The optimal tuning of adaptive flap controller can improve adaptive flap control performance on uncertain operating environments, but the optimization process is usually time-consuming and it is difficult to design proper optimal tuning strategy for the flap control system (FCS). To solve this problem, a novel adaptive flap controller is designed based on a high-efficient differential evolution (DE) identification technique and composite adaptive internal model control (CAIMC) strategy. The optimal tuning can be easily obtained by DE identified inverse of the FCS via CAIMC structure. To achieve fast tuning, a high efficient modified adaptive DE algorithm is proposed with new mutant operator and varying range adaptive mechanism for the FCS identification. A tradeoff between optimized adaptive flap control and low computation cost is successfully achieved by proposed controller. Simulation results show the robustness of proposed method and its superiority to conventional adaptive IMC (AIMC) flap controller and the CAIMC flap controllers using other DE algorithms on various uncertain operating conditions. The high computation efficiency of proposed controller is also verified based on the computation time on those operating cases. PMID- 29576373 TI - Dual-stage periodic event-triggered output-feedback control for linear systems. AB - This paper proposes an event-triggered control framework, called dual-stage periodic event-triggered control (DSPETC), which unifies periodic event-triggered control (PETC) and switching event-triggered control (SETC). Specifically, two period parameters h1 and h2 are introduced to characterize the new event triggering rule, where h1 denotes the sampling period, while h2 denotes the monitoring period. By choosing some specified values of h2, the proposed control scheme can reduce to PETC or SETC scheme. In the DSPETC framework, the controlled system is represented as a switched system model and its stability is analyzed via a switching-time-dependent Lyapunov functional. Both the cases with/without network-induced delays are investigated. Simulation and experimental results show that the DSPETC scheme is superior to the PETC scheme and the SETC scheme.

AB - BACKGROUND: Vesicoureteral reflux (VUR) is an important urologic anomaly that causes renal injury in children with febrile urinary tract infection (UTI). The present study aimed to evaluate the associations of abnormalities detected on technetium-99m-labeled dimercaptosuccinic acid (DMSA) scans, focusing on the association with VUR of the levels of relative decrease in kidney function and cortical defects after a first febrile UTI in children. METHODS: All 171 children underwent ultrasonography, DMSA scan and voiding cystourethrography (VCUG). The features of ultrasound and DMSA scans were compared between patients with (n = 48) and without VUR (n = 123). The relative uptake (RU) by each kidney was derived from the absolute value of the differences between the value for RU of radionuclide in the right kidney and that in the left kidney. The extent of cortical defects (ECD) was graded according to the number of compartments that contained cortical defect in both kidneys (right upper/right lower, left upper/left lower). Receiver operating characteristic curves were constructed to examine the diagnostic value of these parameters of ultrasound and DMSA scans for predicting VUR. RESULTS: The ratio of patients having hydronephrosis on ultrasound or cortical defects on DMSA scan did not differ significantly between VUR and non-VUR groups. However, the absolute values of the RU and the scores for ECD were significantly higher in the VUR group than in the non-VUR group. The area under the curves for these two parameters were higher than those for the presence of hydronephrosis or the presence of cortical defects or both. CONCLUSION: Decreased relative function and increased extents of cortical defects on DMSA scan may be associated with the presence of VUR. These findings may assist pediatricians to decide whether febrile UTI children need to undergo VCUG. PMID- 29576377 TI - Corrections. PMID- 29576378 TI - How far away the cornfield. Dennis Spencer's journey. PMID- 29576376 TI - Complex Interplay between Epitope Specificity and Isotype Dictates the Biological Activity of Anti-human CD40 Antibodies. AB - Anti-CD40 monoclonal antibodies (mAbs) that promote or inhibit receptor function hold promise as therapeutics for cancer and autoimmunity. Rules governing their diverse range of functions, however, are lacking. Here we determined characteristics of nine hCD40 mAbs engaging epitopes throughout the CD40 extracellular region expressed as varying isotypes. All mAb formats were strong agonists when hyper-crosslinked; however, only those binding the membrane-distal cysteine-rich domain 1 (CRD1) retained agonistic activity with physiological Fc gamma receptor crosslinking or as human immunoglobulin G2 isotype; agonistic activity decreased as epitopes drew closer to the membrane. In addition, all CRD2 4 binding mAbs blocked CD40 ligand interaction and were potent antagonists. Thus, the membrane distal CRD1 provides a region of choice for selecting CD40 agonists while CRD2-4 provides antagonistic epitopes.

AB - The present study examines how both between group (i.e., ethnic group membership) and within group cultural factors (i.e., nativity status, age of immigration, and perceived discrimination) may contribute to anxiety and related symptoms in Latinx with anxiety disorders. Baseline data were examined from patients who participated in one of the largest intervention studies for adults with anxiety disorders in primary care settings; 196 Latinx and 568 NLW (non-Latinx White) patients participated. Proportions of anxiety disorders were similar between Latinx and NLWs; however, Latinx, on average, had a greater number of anxiety disorders than NLWs. Levels of anxiety and depression symptom severity, anxiety sensitivity, and mental functional impairment were similar between the ethnic groups. Latinx expressed greater somatization and physical functional impairment than NLWs. Among Latinx, perceived discrimination, but not other cultural variables, was predictive of mental health symptoms while controlling for age, gender, education, and poverty. Overall, these findings suggest more similarities than differences in types and levels of anxiety and anxiety-related impairment, with some important exceptions, including greater levels of somatization and physical functional impairment among Latinx patients. Further, perceived discrimination may be an important factor to consider when examining risk for greater symptom burden among Latinx with anxiety. PMID- 29576375 TI - Fc Effector Function Contributes to the Activity of Human Anti-CTLA-4 Antibodies. AB - With the use of a mouse model expressing human Fc-gamma receptors (FcgammaRs), we demonstrated that antibodies with isotypes equivalent to ipilimumab and tremelimumab mediate intra-tumoral regulatory T (Treg) cell depletion in vivo, increasing the CD8+ to Treg cell ratio and promoting tumor rejection. Antibodies with improved FcgammaR binding profiles drove superior anti-tumor responses and survival. In patients with advanced melanoma, response to ipilimumab was associated with the CD16a-V158F high affinity polymorphism. Such activity only appeared relevant in the context of inflamed tumors, explaining the modest response rates observed in the clinical setting. Our data suggest that the activity of anti-CTLA-4 in inflamed tumors may be improved through enhancement of FcgammaR binding, whereas poorly infiltrated tumors will likely require combination approaches. PMID- 29576383 TI - Ifosfamide and doxorubicin in the treatment of advanced leiomyosarcoma. AB - Leiomyosarcomas (LMS) are rare tumors with poor prognosis owing to the high rate of recurrent and metastatic disease. The combination of doxorubicin (Adriamycin) plus ifosfamide and mesna (AIM) results in moderate response rates of 10%-30%. The aim of this study was to assess the efficacy of the AIM regimen along with multimodality treatment including surgery and radiotherapy in patients with LMS. The clinicopathologic characteristics and outcomes of 51 patients with recurrent or metastatic LMS diagnosed between 2000 and 2014 who received the AIM regimen were analyzed retrospectively. Treatment consisted of ifosfamide 2500mg/m2 on days 1-3 (with mesna 2500mg/m2 days 1-3, 4-hour i.v. infusion), and doxorubicin 60mg/m2 on day 1 (2-hour i.v. infusion), which was repeated every 21 days. The mean age of the patients at diagnosis was 48.9 +/- 11.2 years. A total of 42 patients were females (82.4%). The primary tumor site was the uterus in 30 (58.8%) patients. The most common metastatic sites were lung and liver. The median follow-up was 27.9 months (min: 4.3 max: 164.8). The median progression free survival was 6.7 months (95% CI: 4.1-9.2). The median overall survival (OS) was 24.6 months (95% CI: 16.2-33.0). The overall response rate was 12% (6/51 pts). Response rates were higher in patients with uterine LMS (17%) compared with those with nonuterine LMS (5%); however, the OS times were similar. Surgical intervention for local or distant recurrence was associated with improved median OS (41 vs 16.6 months, P < 0.001). Myelosuppression was the major toxicity of this combination. In our study, the AIM regimen was effective in patients with LMS. Resection of local or distant recurrence was found to improve survival in our study. PMID- 29576384 TI - Assessing social-pragmatic inferencing skills in children with autism spectrum disorder. AB - By utilizing the Pragma test this study investigated how sixteen five- to ten year-old children with autism spectrum disorder (ASD) and sixteen typically developing (TD) children comprehended contextually challenging scenarios demanding 1) contextual inference with theory of mind (ToM), 2) contextual inference without ToM, 3) relevant use of language, 4) recognition of feelings, and 5) understanding false beliefs. The study also compared children's ability to explain their own correct answers. In addition, this study evaluated the sensitivity of three different methods for discriminating the children with ASD from the TD children: 1) the Pragma test, 2) the Social Interaction Deviance Composite (SIDC) of Children's Communication Checklist-2 (CCC-2), and 3) the Theory of Mind subtest of the Developmental Neuropsychological Assessment, Second edition (NEPSY-II). The results showed that children with ASD differed from TD children in questions demanding context utilization. However, the demand of mind reading in utterance interpretation increased the difference between groups. Compared to TD children, children with ASD had more difficulties in explaining how they had used context to arrive at the correct answer. The discrimination power for detecting children with ASD from TD children was excellent in the Pragma test, good in the SIDC CCC-2 and fair in the Theory of Mind subtest of NEPSY-II. This study showed that by using contextually sensitive materials, such as the Pragma test, it is possible to detect the social-pragmatic inferencing difficulties of high-functioning children with ASD in structured test situations and not only in real-life situations or by using parental reports. PMID- 29576385 TI - Analysis of morphological variability and heritability in the head of the Argentine Black and White Tegu (Salvator merianae): undisturbed vs. disturbed environments. AB - The heterogeneity of biotic and abiotic factors influencing fitness produce selective pressures that promote local adaptation and divergence among different populations of the same species. In order for adaptations to be maintained through evolutionary time, heritable genetic variation controlling the expression of the morphological features under selection is necessary. Here we compare morphological shape variability and size of the cephalic region of Salvator merianae specimens from undisturbed environments to those of individuals from disturbed environments, and estimated heritability for shape and size using geometric morphometric and quantitative genetics tools. The results of these analyzes indicated that there are statistically significant differences in shape and size between populations from the two environments. Possibly, one of the main determinants of cephalic shape and size is adaptation to the characteristics of the environment and to the trophic niche. Individuals from disturbed environments have a cephalic region with less shape variation and also have a larger centroid size when compared to individuals from undisturbed environments. The high heritability values obtained for shape and size in dorsal view and right side view indicate that these phenotypic characters have a great capacity to respond to the selection pressures to which they are subjected. Data obtained here could be used as an important tool when establishing guidelines for plans for the sustainable use and conservation of S. merianae and other species living in disturbed areas.

AB - The novel clinical data for myeloma that were presented in the 2017 Annual Meeting of the American Society of Hematology are summarized here. Studies with curative approach (CESAR) or prolonging progression-free survival (CENTAURUS) for patients with high-risk smoldering multiple myeloma (SMM) are described. Updated data from large phase III studies for patients with newly diagnosed MM (NDMM) who are eligible for autologous stem cell transplantation (ASCT) (EMN02, MRC XI) are described, along with the results of studies using novel anti-myeloma drug combinations for induction, consolidation, and maintenance as first-line therapy. The role of minimal residual disease for patients with MM is also discussed. We also present the results of novel phase III studies in patients with NDMM who are not eligible for ASCT (ALCYONE) and new data for their treatment. Recent updates of important studies in the field of relapsed/refractory MM (ASPIRE, POLLUX) along with novel immunotherapy approaches (anti-BCMA monoclonal antibodies, CART cells) are also reported. Finally, levofloxacin prophylaxis reduces febrile episodes and death events in NDMM, whereas 2 doses of high-dose influenza vaccine seem to maintain higher rates of seroprotection compared with those who received standard vaccination. All these data provide the basis for possible changes in the way we manage myeloma in the near future trying to "cure" the disease in many patients. PMID- 29576387 TI - Functional Divergence of Delta and Mu Opioid Receptor Organization in CNS Pain Circuits. AB - Cellular interactions between delta and mu opioid receptors (DORs and MORs), including heteromerization, are thought to regulate opioid analgesia. However, the identity of the nociceptive neurons in which such interactions could occur in vivo remains elusive. Here we show that DOR-MOR co-expression is limited to small populations of excitatory interneurons and projection neurons in the spinal cord dorsal horn and unexpectedly predominates in ventral horn motor circuits. Similarly, DOR-MOR co-expression is rare in parabrachial, amygdalar, and cortical brain regions processing nociceptive information. We further demonstrate that in the discrete DOR-MOR co-expressing nociceptive neurons, the two receptors internalize and function independently. Finally, conditional knockout experiments revealed that DORs selectively regulate mechanical pain by controlling the excitability of somatostatin-positive dorsal horn interneurons. Collectively, our results illuminate the functional organization of DORs and MORs in CNS pain circuits and reappraise the importance of DOR-MOR cellular interactions for developing novel opioid analgesics. PMID- 29576389 TI - Inter-areal Balanced Amplification Enhances Signal Propagation in a Large-Scale Circuit Model of the Primate Cortex. AB - Understanding reliable signal transmission represents a notable challenge for cortical systems, which display a wide range of weights of feedforward and feedback connections among heterogeneous areas. We re-examine the question of signal transmission across the cortex in a network model based on mesoscopic directed and weighted inter-areal connectivity data of the macaque cortex. Our findings reveal that, in contrast to purely feedforward propagation models, the presence of long-range excitatory feedback projections could compromise stable signal propagation. Using population rate models as well as a spiking network model, we find that effective signal propagation can be accomplished by balanced amplification across cortical areas while ensuring dynamical stability. Moreover, the activation of prefrontal cortex in our model requires the input strength to exceed a threshold, which is consistent with the ignition model of conscious processing. These findings demonstrate our model as an anatomically realistic platform for investigations of global primate cortex dynamics. PMID- 29576388 TI - Glycinergic Inhibitory Plasticity in Binaural Neurons Is Cumulative and Gated by Developmental Changes in Action Potential Backpropagation. AB - Utilization of timing-based sound localization cues by neurons in the medial superior olive (MSO) depends critically on glycinergic inhibitory inputs. After hearing onset, the strength and subcellular location of these inhibitory inputs are dramatically altered, but the cellular processes underlying this experience dependent refinement are unknown. Here we reveal a form of inhibitory long-term potentiation (iLTP) in MSO neurons that is dependent on spiking and synaptic activation but is not affected by their fine-scale relative timing at higher frequencies prevalent in auditory circuits. We find that iLTP reinforces inhibitory inputs coactive with binaural excitation in a cumulative manner, likely well suited for networks featuring persistent high-frequency activity. We also show that a steep drop in action potential size and backpropagation limits induction of iLTP to the first 2 weeks of hearing. These intrinsic changes would deprive more distal inhibitory synapses of reinforcement, conceivably establishing the mature, soma-biased pattern of inhibition.

PMID- 29576390 TI - Role for Wnt Signaling in Retinal Neuropil Development: Analysis via RNA-Seq and In Vivo Somatic CRISPR Mutagenesis. AB - Screens for genes that orchestrate neural circuit formation in mammals have been hindered by practical constraints of germline mutagenesis. To overcome these limitations, we combined RNA-seq with somatic CRISPR mutagenesis to study synapse development in the mouse retina. Here synapses occur between cellular layers, forming two multilayered neuropils. The outer neuropil, the outer plexiform layer (OPL), contains synapses made by rod and cone photoreceptor axons on rod and cone bipolar dendrites, respectively. We used RNA-seq to identify selectively expressed genes encoding cell surface and secreted proteins and CRISPR-Cas9 electroporation with cell-specific promoters to assess their roles in OPL development. Among the genes identified in this way are Wnt5a and Wnt5b. They are produced by rod bipolars and activate a non-canonical signaling pathway in rods to regulate early OPL patterning. The approach we use here can be applied to other parts of the brain. PMID- 29576392 TI - Clinical outcome and cerebrospinal fluid profiles in patients with tick-borne encephalitis and prior vaccination history. AB - BACKGROUND: Tick-borne encephalitis (TBE) is endemic in southern and eastern districts of Germany. Approximately 10-14% of the infected individuals suffer from long-term disability and in 1.5-3.6% the course is fatal. Two well-tolerated vaccines are available, which provide high protection and which have been confirmed in several field studies. Here we investigate clinical course, long term outcome and cerebrospinal fluid (CSF) characteristics of TBE cases with a prior history of any vaccination as well as real vaccination breakthrough (VBT). METHODS: A case series of 11 patients with a prior history of vaccination, part of a recently published lager cohort of 111 TBE cases. Evaluation included clinical data, degree of disability (modified RANKIN scale, mRS) and analysis of CSF and serum samples. Furthermore, metadata for extended analysis on clinical outcome of TBE with VBT were analysed. RESULTS: One patient had a clear VBT and ten of them had irregular vaccinations schedules (IVS). Infection severity did not differ in patients with IVS as compared to a non-vaccinated control cohort (median mRS: both 3.0) but these patients showed a stronger cellular immune response as measured by CSF pleocytosis (IVS, 205 cells/MUL versus non-vaccinated control, 114 cell/MUL, P < 0.05) and by differential pattern of CSF (intrathecal) immunoglobulin synthesis. However, shift analysis of VBT metadata using linear-by linear association revealed a more serious course of TBE in patients with VBT than in a non-vaccinated control cohort (chi2 = 9.95, P = 0.002). Furthermore, ordinal logistic regression analysis showed that VBT patients had an age corrected, 2.65 fold (CI: 1.110-6.328; chi2 = 4.813; p = 0.028) significant higher risk to suffer from moderate or severe infections, respectively. CONCLUSION: A history of IVS surprisingly seems to have no impact on the clinical course of TBE but may leave marks in the specific brain immune response. VBT patients, however, carry an age-independent, significant risk to experience a severe infection. PMID- 29576393 TI - Peroxiredoxins are important for the regulation of hydrogen peroxide concentrations in ticks and tick cell line. AB - Ticks are obligate hematophagous ectoparasites, as they need to feed blood from vertebrate hosts for development. Host blood contains high levels of iron. Host derived iron may lead to high levels of reactive oxygen species (ROS), including hydrogen peroxide (H2O2). Since a high concentration of H2O2 causes serious damage to organisms, this molecule is known to be a harmful chemical compound for aerobic organisms. On the other hand, the transparent method is compatible with chemical fluorescent probes. Therefore, we tried to establish the visualizing method for H2O2 in unfed tick tissues. The combination method of a chemical fluorescent probe (BES-H2O2-Ac) with the transparent method, Scale, demonstrated in unfed tick tissues that H2O2 and paraquat could induce oxidative stress in the tissues, such as the midgut and ovary. In addition, an H2O2 detection method using BES-H2O2-Ac was established in Ixodes scapularis embryo-derived cell line (ISE6) in vitro to evaluate the antioxidant activity of peroxiredoxins (PRXs), H2O2 scavenging enzymes, against H2O2 in the cells. The effects of paraquat in ISE6 cells were also observed in the PRXs gene-silenced ISE6 cells. A high intensity of H2O2 fluorescence induced by paraquat was observed in the PRX gene knockdowned cells. These results suggest that H2O2 and paraquat act as an H2O2 inducer, and PRX genes are important for the regulation of the H2O2 concentration in unfed ticks and ISE6 cells. Therefore, this study contributes to the search for H2O2 visualization in ticks and tick cell line and furthers understanding of the tick's oxidative stress induced by H2O2. PMID- 29576394 TI - Characterization of a beta2 adrenergic receptor protein precursor in the European eel (Anguilla anguilla) and its tissue distribution across silvering. AB - This study provides the characterization and tissue distribution of a beta2-AR in the female European eel during silvering, aiming to better understand the adrenergic system involvement in this critical maturation event. A putative beta2 AR (ADRB2) mRNA was cloned and sequenced. Amino acid residues and motifs important for ligand binding are generally conserved across fish and between fish and mammals, although the occurrence of some sequence variabilities may explain the noted peculiarities of eel AR interaction with pharmacological ligands. The tissue distribution of the ADRB2 gene product was analyzed in five tissues of the eel at different silvering stages and compared with that of the ADRA1 mRNA encoding an alpha1-AR subtype. On the whole, data suggested that relative ADRA1/ADRB2 tissue expression across silvering is part of the preparatory (molecular) adjustments required to face changes in habitats and migration efforts. PMID- 29576395 TI - Effect of an acrylic terpolymer barrier film beneath transparent catheter dressings on skin integrity, risk of dressing disruption, catheter colonisation and infection. AB - OBJECTIVES: We assessed the effect of a skin-protective terpolymer barrier film around the catheter insertion site on frequency of dressing disruptions and skin integrity issues (hyperaemia, skin irritation, residues of adhesives and moisture under the dressing). Secondary outcomes included colonisation of the central venous catheter (CVC) and rates of central line-associated bloodstream infection. RESEARCH METHODOLOGY: A monocentric, open-label, randomised controlled trial was performed comparing a control group receiving standard transparent catheter dressings without the skin-protecting barrier film and an intervention group receiving a transparent chlorhexidine-impregnated dressing with use of the skin protective acrylic terpolymer barrier film (3MTM CavilonTM No - Sting Barrier Film, 3 M Health Care, St. Paul, MN, USA). RESULTS: Sixty patients were enrolled and randomised in the study accounting for 60 central venous catheters and a total of 533 catheter days. Dressing disruptions occurred more frequently and at sooner time point in the control group. Skin integrity issues were significantly less observed in the intervention group. No differences in CVC colonisation or central line-associated bloodstream infection were observed. CONCLUSIONS: The application of a barrier film creating a skin-protective polymer layer beneath transparent catheter dressings is associated with less dressing disruptions and skin integrity issues without altering the risk of infectious complications if used in combination with a chlorhexidine-impregnated catheter dressing. PMID- 29576396 TI - Ancestry estimation of three Mediterranean populations based on cranial metrics. AB - The estimation of ancestry is an essential benchmark for positive identification of heavily decomposed bodies that are recovered in a variety of death and crime scenes. This is especially true when reconstructing the biological profile of the deceased as most methods for sex, age and stature estimation are population specific. Ancestry estimation methods vary from traditional morphological assessment of cranial features and biometric quantification to computer-aided shape analysis and classification with specialised software. The current paper aims to explore population differences between three neighbouring countries (Greece, Cyprus and Turkey) that have been in constant interaction through conflicts and population movements from the ancient past to the present day, through cranial measurements. The sample consists of 160 dry crania of Greek origin, 137 dry crania of Greek-Cypriot of origin Cyprus and 380 CT scans from Turks individuals. Twelve measurements were taken in both dry and virtual skulls. Data were submitted to principal component analysis and discriminant function analysis. Intra- and inter-observer error as well as the measurement error between virtual and physical measurements were quantified using TEM, rTEM and R. Measurement error was very low in all cases. Classification accuracy for cross validated data ranged from 74.1 to 97.9%. The highest accuracy was obtained for the Turks sample both in males and females. The results are in accordance with genetic data on the three populations. These results create great confidence in the application of the produced functions in forensic cases requiring ancestry estimation in Cyprus, specifically to unidentified individuals from the 1974 conflict. In addition, these standards can be applied in other forensic situations where ethnicity is an issue but the geographic area of origin is limited to the area encompassing Turkey, Cyprus and Greece. PMID- 29576397 TI - Visual Rating Scales of White Matter Hyperintensities and Atrophy: Comparison of Computed Tomography and Magnetic Resonance Imaging. AB - GOAL: Magnetic resonance imaging (MRI) is the preferred modality for research on structural age-related brain changes. However, computed tomography (CT) is widely available and has practical and cost advantages over MRI for large-scale brain imaging research studies in acutely unwell patients. However, the relationships between MRI and CT measures of white matter hyperintensities (WMH) and atrophy are unclear. We examined the relationships between visual ratings of WMH, atrophy, and old infarcts in patients who had both CT and MRI scans. MATERIALS AND METHODS: Patients who had both CT and MRI scans in the International Stroke Trial-3 were studied. In both modalities, 2 raters independently completed standardized visual rating scales for WMH, and for central and superficial atrophy using a 5-point scale. In addition, 1 rater recorded old infarcts according to size and location. FINDINGS: Seventy patients with a mean age of 69 years were studied. There were moderate to substantial intrarater CT-MRI agreements for periventricular components of WMH scales (weighted Kappaappa = .55 .75). Agreements for basal ganglia ratings were lower (weighted Kappaappa = .18 .44), partly because of the misclassification of prominent perivascular spaces. Atrophy scales showed moderate to substantial CT-MRI agreements (weighted Kappaappa = .44-.70). MRI was more sensitive in the detection of smaller infarcts and cavitated lesions. CONCLUSIONS: Standardized visual rating scales of white matter lesions and atrophy mostly show substantial agreement between CT and MRI. Clinical CT scans have a strong potential for wider exploitation in research studies, particularly in acutely unwell populations. PMID- 29576398 TI - Early Recovery of Aphasia through Thrombolysis: The Significance of Spontaneous Speech. AB - BACKGROUND: Aphasia is one of the most devastating stroke-related consequences for social interaction and daily activities. Aphasia recovery in acute stroke depends on the degree of reperfusion after thrombolysis or thrombectomy. As aphasia assessment tests are often time-consuming for patients with acute stroke, physicians have been developing rapid and simple tests. The aim of our study is to evaluate the improvement of language functions in the earliest stage in patients treated with thrombolysis and in nontreated patients using our rapid screening test. MATERIALS AND METHODS: Our study is a single-center prospective observational study conducted at the Stroke Unit of the University Medical Hospital of Trieste (January-December 2016). Patients treated with thrombolysis and nontreated patients underwent 3 aphasia assessments through our rapid screening test (at baseline, 24 hours, and 72 hours). The screening test assesses spontaneous speech, oral comprehension of words, reading aloud and comprehension of written words, oral comprehension of sentences, naming, repetition of words and a sentence, and writing words. RESULTS: The study included 40 patients: 18 patients treated with thrombolysis and 22 nontreated patients. Both groups improved over time. Among all language parameters, spontaneous speech was statistically significant between 24 and 72 hours (P value = .012), and between baseline and 72 hours (P value = .017). CONCLUSIONS: Our study demonstrates that patients treated with thrombolysis experience greater improvement in language than the nontreated patients. The difference between the 2 groups is increasingly evident over time. Moreover, spontaneous speech is the parameter marked by the greatest improvement. PMID- 29576399 TI - Chemical Diversity in the G Protein-Coupled Receptor Superfamily. AB - G protein-coupled receptors (GPCRs) are the largest family of cell signaling transmembrane proteins that can be modulated by a plethora of chemical compounds. Systematic cheminformatics analysis of structurally and pharmacologically characterized GPCR ligands shows that cocrystallized GPCR ligands cover a significant part of chemical ligand space, despite their limited number. Many GPCR ligands and substructures interact with multiple receptors, providing a basis for polypharmacological ligand design. Experimentally determined GPCR structures represent a variety of binding sites and receptor-ligand interactions that can be translated to chemically similar ligands for which structural data are lacking. This integration of structural, pharmacological, and chemical information on GPCR-ligand interactions enables the extension of the structural GPCR-ligand interactome and the structure-based design of novel modulators of GPCR function. PMID- 29576400 TI - Asymptomatic congenital lung malformations: Is nonoperative management a viable alternative? AB - INTRODUCTION: The purpose of this study was to evaluate clinical outcomes in children with asymptomatic congenital lung malformations (CLM) who were initially managed nonoperatively. METHODS: An IRB-approved retrospective review was performed on all CLMs at a single tertiary care referral center (Jan 2006-Dec 2016, n=140). Asymptomatic cases that did not undergo elective resection were evaluated for subsequent CLM-related complications based on clinical records and a telephone quality of life survey. RESULTS: Out of 39 (27.9%) who were initially managed nonoperatively, 13 (33%) developed CLM-related symptoms and underwent surgical intervention at a median age of 6.8years (range, 0.7-19.8years). The most common indication for conversion to operative management was pneumonia (78%). Larger lesions, as measured by CT scan, were significantly associated with the need for subsequent surgical intervention (mean maximal diameter, 5.7 vs. 2.9cm; p=0.005). Based on survey data with a median follow up of 3.9years (range, 0.2-13.2years), 17% developed chronic pulmonary symptoms, including cough (11%) and asthma requiring bronchodilators (12%). CONCLUSION: Although these data support nonoperative management as a viable alternative to surgical resection, at least one-third of CLM children eventually develop pneumonia or other pulmonary symptoms. Larger lesions are correlated with an increased risk for eventual surgical resection. LEVEL OF EVIDENCE: Level IV. PMID- 29576401 TI - Longitudinal analysis of hospital charges following injury in a level 1 pediatric trauma system. AB - BACKGROUND: The treatment of injured children contributes substantially to the financial burden of a health care system. The purpose of this study was to characterize these charges at a level-1 pediatric trauma center. METHODS: Financial data for children (<14 years) admitted for traumatic injury from 1/2009 to 12/2014 were analyzed. The charges of the index admission and first two years following discharge were evaluated. RESULTS: 5853 trauma patients were included with average annual charges of $11,128,730. The most common mechanisms of injury were fall (44%), sports (12%), and bike (9%). The median ISS was 6 (IQR 4-10) with a mortality rate of 1.8% and Z-score of 13.04 (p<0.001). The overall total charges per patient during the index admission were $9513. Spinal cord and major abdominal injuries had the greatest charges per patient ($55,560 and $23,618 respectively) primarily owing to hospital LOS. During the first year after discharge, the total charges per patient were $1733, of which spinal cord injury resulted in highest overall ($19,426), owing to inpatient rehabilitation. For all other injury patterns, mean total charges per patient were $2376 (range $791 $3573). CONCLUSIONS: The value proposition in health care requires us to define outcomes relative to costs. Injury severity, major injury location, and hospital length of stay are the highest contributors for the financial burden of pediatric traumatic injury, while inpatient readmissions and inpatient rehabilitation drove higher charges in the years following discharge. TYPE OF STUDY: Clinical Research Paper. LEVEL OF EVIDENCE: II - Cohort Study. PMID- 29576403 TI - A Survey of Wilderness Medicine Analgesia Practice Patterns. AB - INTRODUCTION: In 2014, the Wilderness Medical Society (WMS) published guidelines for the treatment of acute pain in remote settings. We surveyed wilderness medicine providers on self-reported analgesia prescribing practices. METHODS: We conducted a prospective, anonymous survey. Respondents were recruited from the WMS annual symposium in 2016. All willing attendees were included. RESULTS: During the symposium, we collected a total of 124 surveys (68% response rate). Respondent age was 42+/-12 (24-79) years (mean+/-SD with range), 58% were male, and 69% reported physician-level training. All respondents had medical training of varying levels. Of the physicians reporting a specialty, emergency medicine (59%, n=51), family medicine (13%, n=11), and internal medicine (8%, n=7) were reported most frequently. Eighty-one (65%) respondents indicated they prefer a standardized pain assessment tool, with the 10-point numerical rating scale being the most common (54%, n=67). Most participants reported preferring oral acetaminophen (81%, n=101) or nonsteroidal anti-inflammatory drugs (NSAID) (91%, n=113). Of those preferring NSAID, most reported administering acetaminophen as an adjunct (82%, n=101). Ibuprofen was the most frequently cited NSAID (71%, n=88). Of respondents who preferred opioids, the most frequently preferred opioid was oxycodone (26%, n=32); a lower proportion of respondents reported preferring oral transmucosal fentanyl citrate (9%, n=11). Twenty-five (20%, n=25) respondents preferred ketamine. CONCLUSIONS: Wilderness medicine practitioners prefer analgesic agents recommended by the WMS for the treatment of acute pain. Respondents most frequently preferred acetaminophen and NSAIDs. PMID- 29576402 TI - Genomic insight into the taxonomy of Rhizobium genospecies that nodulate Phaseolus vulgaris. AB - Due to the wide cultivation of bean (Phaseolus vulgaris L.), rhizobia associated with this plant have been isolated from many different geographical regions. In order to investigate the species diversity of bean rhizobia, comparative genome sequence analysis was performed in the present study for 69 Rhizobium strains mainly isolated from root nodules of bean and clover (Trifolium spp.). Based on genome average nucleotide identity, digital DNA:DNA hybridization, and phylogenetic analysis of 1,458 single-copy core genes, these strains were classified into 28 clusters, consistent with their species definition based on multilocus sequence analysis (MLSA) of atpD, glnII, and recA. The bean rhizobia were found in 16 defined species and nine putative novel species; in addition, 35 strains previously described as Rhizobium etli, Rhizobium phaseoli, Rhizobium vallis, Rhizobium gallicum, Rhizobium leguminosarum and Rhizobium spp. should be renamed. The phylogenetic patterns of symbiotic genes nodC and nifH were highly host-specific and inconsistent with the genomic phylogeny. Multiple symbiovars (sv.) within the Rhizobium species were found as a common feature: sv. phaseoli, sv. trifolii and sv. viciae in Rhizobium anhuiense; sv. phaseoli and sv. mimosae in Rhizobium sophoriradicis/R. etli/Rhizobium sp. III; sv. phaseoli and sv. trifolii in Rhizobium hidalgonense/Rhizobium acidisoli; sv. phaseoli and sv. viciae in R. leguminosarum/Rhizobium sp. IX; sv. trifolii and sv. viciae in Rhizobium laguerreae. Thus, genomic comparison revealed great species diversity in bean rhizobia, corrected the species definition of some previously misnamed strains, and demonstrated the MLSA a valuable and simple method for defining Rhizobium species. PMID- 29576404 TI - Treatment outcomes in diabetic patients with chronic limb-threatening ischemia. AB - OBJECTIVE: There are conflicting reports about outcomes after infrainguinal bypass for chronic limb-threatening ischemia (CLTI) in patients with diabetes. We compared perioperative outcomes between patients with and patients without diabetes in the current era. METHODS: The National Surgical Quality Improvement Program vascular module, 2011 to 2014, was used to identify patients undergoing infrainguinal revascularization for CLTI. Patients with and without diabetes were compared in terms of presentation, comorbidities, operative approach, and 30-day outcomes. Major adverse limb events (MALEs) included 30-day major reintervention or amputation, and major adverse cardiovascular events (MACEs) included 30-day myocardial infarction, cardiac arrest, stroke, or death. Multivariable logistic regression was used to adjust for baseline differences. RESULTS: We identified 8887 patients undergoing open (5744; 50% diabetic) or endovascular (3143; 62% diabetic) treatment for CLTI. Patients with diabetes were younger and more often nonwhite, nonsmokers, and obese. Patients with diabetes presented more often with tissue loss (71% vs 47%; P < .001) and were more likely to be treated with endovascular intervention (41% vs 29%; P < .001). The 30-day mortality was similar before (open, 3.1% vs 2.8% [P = .53]; endovascular, 2.6% vs 2.1% [P = .37]) and after adjustment for baseline differences (open: odds ratio [OR], 1.1 [95% confidence interval (CI), 0.7-1.5]; endovascular: OR, 1.2 [95% CI, 0.7 2.0]). Patients with diabetes had longer lengths of stay (open, 8 vs 6 days [P < .001]; endovascular, 3 vs 2 days [P < .001]) and higher 30-day readmission rates (open, 21% vs 18% [P < .01]; endovascular, 20% vs 15% [P < .01]); however, these differences were no longer significant after adjustment for baseline differences. Patients with diabetes had a higher rate of MACEs (7.0% vs 5.1%; P < .01) and lower rate of MALEs (8.1% vs 10%; P < .01) after bypass. After adjustment, patients with diabetes still had a lower rate of MALEs (OR, 0.7; 95% CI, 0.6-0.9) but no longer had a higher rate of MACEs (OR, 1.2; 95% CI, 0.9-1.6). CONCLUSIONS: CLTI patients with diabetes undergoing revascularization have similar 30-day outcomes compared with those without diabetes, although they appear to be at lower risk for MALEs after bypass. Prolonged length of stay and readmission in patients with diabetes is not due to underlying diabetic disease but likely secondary to other baseline comorbidities, such as higher rates of tissue loss. Concern for worse perioperative outcomes in patients with diabetes after lower extremity bypass is unsubstantiated and should not discourage a physician from performing an open bypass. PMID- 29576405 TI - A propensity-matched comparison of fenestrated endovascular aneurysm repair and open surgical repair of pararenal and paravisceral aortic aneurysms. AB - OBJECTIVE: This study investigated the outcomes of a current series of patients treated with fenestrated and branched endovascular aneurysm repair (F-BEVAR) or open surgical repair (OSR) for pararenal abdominal aortic aneurysms (pr-AAAs), including juxtarenal, suprarenal, and type IV thoracoabdominal aneurysms. This study compares the outcomes of these procedures from two high-volume centers without the bias induced by a learning curve. METHODS: All patients with pr-AAAs undergoing repair at two centers between January 2010 and June 2016 were included in a prospective database. Patients undergoing F-BEVAR and OSR were propensity matched for age, sex, anatomic criteria (aortic clamp site), coronary artery disease, chronic obstructive pulmonary disease, diabetes, smoking, chronic kidney disease, aneurysm diameter, and previous aortic surgery. The primary end points were mortality and dialysis. Secondary end points included any myocardial ischemia, respiratory and early procedural complications, acute kidney injury (AKI) according to RIFLE criteria (Risk, Injury, Failure, Loss of kidney function, and End-stage renal failure), spinal cord ischemia, a composite of these complications, and postoperative intensive care unit length of stay. During follow-up, all-cause survival and freedom from reintervention were compared, as was the patency of stented vessels and renal and visceral bypasses. Late renal function deterioration was evaluated. RESULTS: In this period, 157 F-BEVAR patients and 119 OSR patients were operated on. After 1:1 propensity matching, the study cohort consisted of 102 F-BEVARs and 102 OSRs. In the matched population, an average of 2.5 vessels were treated per patient. Univariate analysis demonstrated no significant difference in 30-day mortality (2.9% vs 2.0%; P = .68), dialysis (4.9% vs 3.9%; P = 1), cardiac ischemic complications (3.8% vs 5.9%; P = .52), pulmonary complications (5.9% vs 5.9%; P = 1), or any complications (28.4% vs 30.4%; P = .63) in the F-BEVAR and OSR groups, respectively. AKI was significantly lower in the F-BEVAR group than in the OSR group (19.6% vs 52%; P < .001), as was severe AKI (>50% decrease in glomerular filtration rate, 6.9% vs 16.7%; P = .03). There was no spinal cord ischemia. The median intensive care unit length of stay was 1 day in both groups (P = .33). During follow-up, we found occlusions of five stented vessels and three surgical bypasses. Late renal function deterioration was comparable between the two groups. According to Kaplan-Meier estimates, all-cause survival at 24, 48, and 72 months was 85.6%, 66.8%, and 55.8% after F-BEVAR and 90.5%, 82.9%, and 68.5% after OSR (P = .04). Rates of freedom from reintervention were 97.6% vs 97.5% at 24 months, 90.1% vs 93.4% at 48 months, and 63.9% vs 93.4% at 72 months in the F BEVAR and OSR groups (P = .05), respectively. Thus, both all-cause survival and freedom from reintervention were lower in the F-BEVAR group. CONCLUSIONS: This propensity score analysis in patients with pr-AAA undergoing F-BEVAR or OSR suggests no difference in terms of 30-day mortality, dialysis, or organ-specific postoperative complications, with the exception of AKI. Postoperative AKI was significantly higher after OSR, although most patients had recovered before discharge. Our data suggest similar outcomes after F-BEVAR or OSR for pr-AAA. PMID- 29576406 TI - Screening of LDLR and APOB gene mutations in Mexican patients with homozygous familial hypercholesterolemia. AB - BACKGROUND: Familial hypercholesterolemia (FH) is an autosomal dominant disorder that causes accumulation of serum low-density lipoprotein cholesterol and premature cardiovascular disease. It is mainly related to mutations in the LDLR gene. Homozygous FH (HoFH) patients have the most severe form of the disease accounting for a worldwide prevalence of 1:1,000,000. In Mexico, at least 5 cases of HoFH have been reported. OBJECTIVE: The aim of this study was to describe the clinical, biochemical, and molecular data observed in patients with HoFH phenotype. METHODS: We included 13 patients, belonging to 11 families, with clinical and biochemical diagnoses suggestive of HoFH. Molecular analyses of the LDLR and APOB genes were performed by means of polymerase chain reaction followed by Sanger sequencing. RESULTS: The causal mutation of HoFH was found in 8 of 11 unrelated patients. Excepting 1, all were true homozygotes. Six different variants in LDLR were identified: c.-139delCTCCCCCTGC, p.Glu140Lys, p.Asp360His, p.Asn405Lys, p.Ala755Glyfs*7, and p.Leu759Serfs*6. Of these, p.Asp360His and p.Asn405Lys were detected for the first time in Mexico; p.Leu759Serfs*6 showed to be the most frequent (43.7% of the alleles 7/16), and c.-139delCTCCCCCTGC is a new variant located in the promoter region. CONCLUSIONS: This work increases knowledge of biochemical and genetic features in Mexican patients with HoFH. A novel mutation in the LDLR gene promoter was detected: c.-139delCTCCCCCTGC, which possibly inhibits its expression. PMID- 29576407 TI - Treatment Patterns and Clinical Outcomes Among Metastatic Non-Small-Cell Lung Cancer Patients Treated in the Community Practice Setting. AB - INTRODUCTION: Multiple therapeutic options now exist for metastatic non-small cell lung cancer (mNSCLC). In this study we evaluated treatment patterns and outcomes in mNSCLC patients who received first-line (1L), second-line (2L), and third-line (3L) therapy. PATIENTS AND METHODS: A retrospective, observational cohort study was conducted using an electronic health record database of mNSCLC patients who received initial treatment from January 2012 through April 2016, with follow-up through June 2016. Patient characteristics and treatment patterns were characterized. Overall survival (OS) was assessed using the Kaplan-Meier method. RESULTS: We identified 10,689 1L patients. Median age was 68 years, and 5816 (54%) were male. Most patients (6337; 59%) had a performance status of 1, and 8282 (77%) had nonsquamous histology. 1L treatment was chemotherapy in 9969 (93%) patients, and targeted therapy in 685 (6%). Median OS (mOS) for all patients in 1L was 12.3 months (95% confidence interval [CI], 11.9-12.7), and 24.3 months in 1L patients receiving targeted therapy. Among patients who received 2L therapy (n = 4235), 2790 (66%), 718 (17%), and 727 (17%) received chemotherapy, targeted therapy, and immunotherapy, respectively. mOS from 2L therapy was 9.6 months (95% CI, 9.1-10.1). In patients receiving 3L therapy (n = 1580), 921 (58%), 355 (22%), and 304 (19%) received chemotherapy, targeted therapy, and immunotherapy, respectively. mOS from 3L therapy was 8.2 months (95% CI, 7.3-8.7). CONCLUSION: Targeted therapy and immunotherapy was most frequently used in the 2L and 3L setting during the study time frame. Survival differences observed according to treatment types are likely because of biologic differences, and suggest that patients with actionable mutations have a survival advantage. PMID- 29576408 TI - Insomnia and hypertension: A systematic review. AB - Insomnia is a prevalent sleep disorder that is associated with a multitude of health consequences. Particularly, insomnia has been associated with cardiovascular disease and its precursors, such as hypertension and blood pressure (BP) non-dipping. The present systematic review aimed to summarize the evidence on the concurrent and prospective associations between insomnia and hypertension and/or BP. Using electronic search engines (PubMed, SCOPUS, PsycINFO), 5,618 articles published from January 1970 to December 2017 were identified, and 64 met the inclusion criteria (26 to 162,121 participants; age range: 18-100; 46.4% male). Insomnia was based on diagnostic or non-diagnostic criteria. Hypertension was based on self-or physician-reports, antihypertensive medication use, and/or measured BP. Findings indicate that when insomnia is frequent, chronic, and/or accompanied with short sleep duration or objective markers of arousal, there is a strong association with hypertension/BP. Based on limited studies, hypertension did not significantly predict future insomnia in middle-aged adults, but did in older adults. Based on a majority of case-control studies, no differences in BP were found between participants with and without insomnia. Further research is needed to identify putative pathophysiological mechanisms underlying the link between insomnia and hypertension. The impact of insomnia therapy on BP should also be further examined in the future. PMID- 29576409 TI - The Impact of Sex on Alloimmunity. AB - Transplantation outcomes are known to be affected by multiple factors, including donor and recipient sex. Aside from the physiological characteristics of male and female donor allografts, accumulating evidence suggests that additional features underlie sex-specific immune responses that affect graft survival. We discuss here aspects of innate and adaptive alloimmunity that are specific to males and females in the context of underlying genetic and hormonal factors. These differences likely contribute to the observed disparities in graft survival. Understanding these features in more detail may lead to improved strategies for optimizing the results of organ transplantation. PMID- 29576410 TI - The effects of early trauma and the FKBP5 gene on PTSD and the HPA axis in a clinical sample of Gulf War veterans. AB - Previous research indicates that interactions between FKBP5 single nucleotide polymorphisms (SNPs) and child abuse are associated with posttraumatic stress disorder (PTSD) in adulthood. We examined the relationship between the T-allele of the rs1360780 FKBP5 SNP and child abuse on PTSD and the HPA axis in a clinical sample of Gulf War veterans. Genotyping was completed on 266 veterans and 174 veterans additionally participated in a low dose dexamethasone suppression test (DST). The CAPS was used to determine PTSD status and the THQ was used to determine child abuse operationalized as either childhood physical or sexual abuse. Hierarchical regression models were used to assess FKBP5 * child abuse interactions on PTSD, basal cortisol levels, and post DST cortisol levels. The FKBP5 risk allele and child abuse were separately associated with PTSD diagnosis. The risk allele was also associated with significantly lower cortisol levels at baseline. However, no significant FKBP5 * child abuse interaction on PTSD diagnosis, basal cortisol levels, or greater cortisol suppression was observed. Our results suggest that FKBP5 may be a viable biomarker for PTSD. Nonetheless, further work will be required to reconcile our findings with previous reports of an FKBP5 * child abuse interaction on posttraumatic stress response. PMID- 29576411 TI - Are emotional action tendencies and attentional bias related to temperament dimensions in patients with borderline personality disorder? AB - Disturbances in emotion regulation have been identified as a core feature of patients with a borderline personality disorder (BPD). Findings of studies using experimental measures of emotion processing are mixed, which may be partially explained by the heterogeneity of the BPD population. To address this issue, we investigated differences in experimental measures of emotional action tendencies (approach-avoidance behaviour) and attentional bias to emotional stimuli in BPD subtypes. Data of the Approach-Avoidance Task (AAT) and the Emotional Stroop Task (EST) were collected in 140 BPD patients, previously clustered into four BPD subtypes based on temperament dimensions. We investigated (1) the relationship between temperament dimensions and the performance on the AAT and EST and (2) compared performance on these tasks in previous defined BPD subtypes. The results of the present study demonstrated a positive relationship between effortful control (EC) and AAT effect-scores. A higher level of EC was positively associated with a general emotional action tendency towards faces with directed gaze, even when controlling for gender, age and BPD severity. Preliminary results on the comparison of the BPD subtypes demonstrated no significant differences in AAT and EST performance. These findings emphasize the relevance of EC in emotional action tendencies in BPD patients. PMID- 29576413 TI - The effects of antipsychotics on the density of cannabinoid receptors in selected brain regions of male and female adolescent juvenile rats. AB - Antipsychotic drugs have been increasingly prescribed to children and adolescents for treating various mental disorders, such as childhood-onset schizophrenia. The abnormality of endocannabinoid system is involved in the pathophysiology of these disorders in juveniles. This study investigated the effect of antipsychotics on the cannabinoid (CB) receptors in the brain of both male and female juvenile rats. The postnatal rats (PD23+/-1) were administered aripiprazole (1 mg/kg), olanzapine (1 mg/kg), risperidone (0.3 mg/kg) or vehicle (control) for 3 weeks. Quantitative autoradiography was used to investigate the binding densities of [3H]CP-55940 (an agonist for CB1R and CB2R) and [3H]SR141716A (a selective CB1R antagonist) in the rat brains. Risperidone significantly upregulated the [3H]CP55940 and [3H]SR141716A bindings in the prefrontal cortex (PFC), nucleus accumbens core (NAcC), nucleus accumbens shell (NAcS), cingulate cortex (Cg), and the caudate putamen (CPu) in male rats. Moreover, aripiprazole significantly elevated the [3H]SR141716A binding in the Cg and NAcS of female rats. Furthermore, there is an overall higher [3H]SR141716A binding level in the brain of female rats than male rats. Therefore, treatment with aripiprazole, olanzapine and risperidone could induce differential and gender specific effects on the binding density of cannabinoid receptors in the selected brain regions of childhood/adolescent rats. PMID- 29576412 TI - Oppositional behavior and longitudinal predictions of early adulthood mental health problems in chronic tic disorders. AB - Chronic tic disorders (TD) are associated with a number of psychological problems such as attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive behavior (OCB), oppositional-defiant disorder (ODD) as well as anxious and depressive symptoms. ODD is often considered a risk factor for many psychological symptoms and recent work suggests that different ODD dimensions show independent predictions of later psychological problems. This study examined the longitudinal predictions between ODD dimensions of Irritability and Defiance and the most frequent comorbidities in TD from childhood to early adulthood. From an initial sample of 135, parent reports were obtained on 58 participants with TD using standard clinical questionnaires and semi-structured interviews. Defiance symptoms decreased from baseline to follow-up whereas Irritability symptoms were more stable over time. In multiple regressions, Irritability in childhood predicted anxiety and OCB in early adulthood while Defiance in childhood predicted ADHD and conduct disorder symptoms in early adulthood. No developmental link was found for depressive symptoms. Results indicate that ODD dimensions are developmentally linked to both internalizing and externalizing adult mental health symptoms in TD. PMID- 29576414 TI - Imaging and Pathologic findings of Hepatic Small Vessel Hemangioma. AB - Hepatic small vessel hemangioma represents a distinct yet very rare pathologic entity of the liver. The entity has also been in the past referred to as adult capillary hemangioma of the liver and congenital noninvoluting hemangioma. Imaging findings are not definitive and biopsy or resection is ultimately necessary. Pathologically these represent vasoformative abnormalities with infiltrative margins that can potentially mimic hepatic angiosarcoma. Immunohistochemistry can help differentiate hepatic small vessel hemangioma from angiosarcoma. Given the infiltrative growth pattern and unknown outcomes, resection and or close follow up has been recommended. Recently the term hepatic small vessel neoplasm has been coined in view of the unknown outcomes and some concerning findings on molecular analysis. We report 2 cases of this unusual entity and describe its imaging, gross pathologic, histopathologic, and immunohistochemical features.

PMID- 29576415 TI - Prevalence and Severity of Off-Centering During Diagnostic CT: Observations From 57,621 CT scans of the Chest, Abdomen, and/or Pelvis. AB - PURPOSE: To determine distances between patient centroid and gantry isocenter during CT imaging of the chest, abdomen, and/or pelvis, and to evaluate differences based on patient gender, scan region, patient position, and gantry aperture. MATERIALS AND METHODS: A water phantom and an anthropomorphic phantom were imaged in the centered position in the CT gantry and at several off-centered positions. Additionally, data from 57,621 adult chest, abdomen, and/or pelvic CT acquisitions were evaluated. Data were analyzed with an analysis of variance using the centroid-to-isocenter data as the dependent variable and the other parameters as independent variables. RESULTS: The majority of patient acquisitions (83.7% (48271/57621)) were performed with the patient's centroid positioned below isocenter (mean 1.7 cm below isocenter (SD 1.8 cm); range 12.1 cm below to 7.8 cm above isocenter). Off-centering in the x-axis was less severe (mean 0.01 cm left of isocenter (SD 1.6 cm)). Distance between centroid and isocenter in the y-axis did not differ as a function of sex but did differ based on scan region, patient position, and gantry aperture. CONCLUSION: Off-centering is common during CT imaging and has been previously demonstrated to impact dose and image quality. PMID- 29576417 TI - TACE plus external beam radiotherapy in liver cancer. PMID- 29576418 TI - Major health-care companies merge in the USA. PMID- 29576419 TI - Patterns of care and outcomes for glioblastoma in patients with poor performance status. AB - PURPOSE/OBJECTIVES: While treatment with tumor resection followed by chemoradiation is generally the accepted standard of care for glioblastoma (GBM), the treatment for patients with poor performance status remains uncertain. Therefore we sought to examine patterns of care and survival outcomes among patients with poor performance status utilizing a large hospital database. METHODS/MATERIALS: We queried the National Cancer Database (NCDB) for patients with GBM and Karnofsky performance status (KPS) <60 between 2010 and 2013. Data was collected regarding surgery, radiation therapy and chemotherapy. Logistic regression was used to analyze predictors for utilization of chemoradiation. The Kaplan-Meier method was used to compare survival between those who received chemoradiation to radiation alone and Cox regression was performed to assess covariates associated with survival. RESULTS: There were 488 patients included in the analysis of which 51.2% received chemoradiation and 46.1% underwent subtotal or gross total resection. None of the factors analyzed were significantly associated with increased likelihood of receiving chemoradiation over radiation alone. Survival data was available for 236 patients that received radiation therapy with and without combination chemotherapy. The median overall survival for those receiving radiation alone was 3.6 months and 8.7 months in those who received chemoradiation (p < 0.001). On multivariable Cox regression, increasing age (HR 1.80-2.10, p = 0.001) was associated with worse survival while subtotal/gross total resection (HR 0.60, p = 0.003) and chemoradiation (HR 0.57, CI 0.40-0.83, p = 0.003) were associated with improved survival. CONCLUSION: Even patients with poor performance status had better survival outcomes when they received treatment with chemoradiation over radiation alone.

PMID- 29576422 TI - Late characterisation of cardiac effects following anthracycline and trastuzumab treatment in breast cancer patients. AB - BACKGROUND: Anthracycline (A) and trastuzumab (T) chemotherapy have well recognized cardiac toxicity, potentially leading to significant morbidity and mortality. Our previous work in 46 prospectively enrolled breast cancer patients showed early left ventricular (LV) and right ventricular (RV) function decline at 1 and 3 months, but only persistent RV dysfunction at 12 months which correlated with myocardial oedema observed early (1 and 3 months) after administration of chemotherapy regimes. METHOD: To investigate late cardiac effects, the same cohort were re-imaged with advanced Cardiovascular Magnetic Resonance (CMR) imaging including T1 mapping 5 +/- 1 year post chemotherapy. RESULTS: Twenty-six out of 46 (50%) patients underwent follow-up imaging. A statistical but non clinically significant decrease was observed in LV ejection fraction (EF) from baseline to 5 years (72.2 +/- 6.6 to 65.4 +/- 9.3, p < 0.005). Subjects with initial drop of LVEF by >10% at 3 months (n = 5) or at 12 months (n = 3) did not demonstrate any difference in LV or RVEF at 5 years. No correlation was observed between myocardial oedema and LV or RVEF at 5 years. At 5 years, T1 values were within normal limits overall (935 +/- 48 ms). One patients had significantly elevated (>1000 ms) T1 values with no correlation to LV or RVEF. No subjects demonstrated replacement myocardial fibrosis at 5 years. CONCLUSION: Using advanced CMR, contemporary chemotherapy regimes demonstrate minimal long-term cardiac toxicity. There is minimal diffuse and no replacement fibrosis as demonstrated by LGE, following chemotherapy. This study suggests limiting serial imaging in these patients at 12 months post chemotherapy. PMID- 29576423 TI - Iatrogenic pathology of the urinary bladder. AB - Intravesical immunotherapy, chemotherapy, and neoadjuvant systemic chemotherapy are among the most frequent therapeutic procedures to treat malignancies of the urinary bladder. These treatment modalities produce reactive morphologic changes in the urothelium that can mimic urothelial carcinoma in situ, urothelial dysplasia or true invasive urothelial neoplasia. Mitomycin C used after transurethral resection of bladder tumor to reduce recurrences, BCG intravesical immunotherapy to treat high risk non-muscle invasive bladder cancer and urothelial carcinoma in situ, and platinum-based systemic chemotherapy to improve post-cystectomy disease-specific survival some of the causes of therapy related atypia in urinary bladder. In addition, a number of systemic drugs in use to treat other systemic diseases, such as cyclophosphamide used to treat certain auto-immune disorders or hematologic malignancies, or the anesthetics ketamine increasingly used as illegal recreational drug, may produce similarly relevant atypical changes in the urothelium, and therefore, need to be differentiated from intraepithelial neoplasia. Immunohistochemical approach to reactive urothelium from CIS using CK20, p53, and CD44 may also be of utility in the pos-therapy scenario. PMID- 29576424 TI - A Temporal Transcriptional Switch Governs Stem Cell Division, Neuronal Numbers, and Maintenance of Differentiation. AB - The importance of producing the correct numbers of neurons during development is illustrated by both evolutionary enhancement of cognitive capacities in larger brains, and developmental disorders of brain size. In humans, increased neuronal numbers during development is speculated to partly derive from a unique subtype of neural stem cells (NSCs) that undergo a phase of expansion through symmetric self-amplifying divisions before generating neurons. Symmetric amplification also appears to underlie adult neural stem maintenance in the mouse. However, the mechanisms regulating this behavior are unclear. We report the discovery of self amplifying NSCs in Drosophila and show that they arise by a spatiotemporal conversion of classical self-renewing NSCs. This conversion is regulated by a temporal transition in the expression of proneural transcription factors prior to cell division. We find a causal link between stem cell self-amplification and increased neuronal numbers. We further show that the temporal transcriptional switch controls both stem cell division and subsequent neuronal differentiation. PMID- 29576425 TI - The Circadian Clock Sets the Time of DNA Replication Licensing to Regulate Growth in Arabidopsis. AB - The circadian clock and cell cycle as separate pathways have been well documented in plants. Elucidating whether these two oscillators are connected is critical for understanding plant growth. We found that a slow-running circadian clock decelerates the cell cycle and, conversely, a fast clock speeds it up. The clock component TOC1 safeguards the G1-to-S transition and controls the timing of the mitotic cycle at early stages of leaf development. TOC1 also regulates somatic ploidy at later stages of leaf development and in hypocotyl cells. The S-phase is shorter and delayed in TOC1 overexpressing plants, which correlates with the diurnal repression of the DNA replication licensing gene CDC6 through binding of TOC1 to the CDC6 promoter. The slow cell-cycle pace in TOC1-ox also results in delayed tumor progression in inflorescence stalks. Thus, TOC1 sets the time of the DNA pre-replicative machinery to control plant growth in resonance with the environment. PMID- 29576426 TI - A Pilot Study of Apatinib as Third-Line Treatment in Patients With Heavily Treated Metastatic Colorectal Cancer. AB - BACKGROUND: Antiangiogenic therapy has shown improved clinical outcome in metastatic colorectal cancer (mCRC). After the failure of standard treatments, regorafenib and TAS-102 would be recommended for patients with mCRC, however, they have not been approved in China during this study period. PATIENTS AND METHODS: This pilot study aimed to assess the efficacy and safety of apatinib, a novel oral inhibitor targeting vascular endothelial growth factor receptor 2, as third-line treatment for patients with mCRC refractory to standard therapies. In this retrospective study, all patients received apatinib treatment until progressive disease (PD), death, unacceptable toxicity, and curative surgery. The dose or treatment schedule was modified according to the physician's discretion according to the toxicity profiles. RESULTS: Between March 2015 and June 2017, 36 patients were enrolled and eligible for evaluation of the safety and efficacy. One patient (2.8%) achieved complete response, 3 (8.3%) achieved partial response, 24 (66.7%) achieved stable disease, and 8 (22.2%) PD. The objective response rate and the disease control rate were 11.1% (4 of 36), and 77.8% (28 of 36), respectively. Moreover, the median overall survival (OS) since the initiation of first-line treatment was 33.2 months. The median progression-free survival (PFS) and median OS from apatinib treatment were 4.8 and 10.1 months, respectively. Intergroup analysis showed that there was no significant difference in median PFS and median OS between patients who were previously treated with and without bevacizumab. The most common Grade 3 to 4 adverse reactions were hand foot syndrome, hypertension, and proteinuria. CONCLUSION: Our results suggested that apatinib was active as a third-line treatment of refractory mCRC with a manageable tolerability profile. In addition, preliminary data suggested that the efficacy of apatinib would not be affected by previous bevacizumab treatment. Further prospective randomized controlled clinical trials are urgently needed. PMID- 29576427 TI - Dermatologic Toxicity Occurring During Anti-EGFR Monoclonal Inhibitor Therapy in Patients With Metastatic Colorectal Cancer: A Systematic Review. AB - Monoclonal antibody inhibitors of the epidermal growth factor receptor (EGFR) have been shown to improve outcomes for patients with metastatic colorectal cancer (mCRC) without RAS gene mutations. However, treatment with anti-EGFR agents can be associated with toxicities of the skin, nails, hair, and eyes. Because these dermatologic toxicities can result in treatment discontinuation and affect patient quality of life, their management is an important focus when administering anti-EGFR monoclonal antibodies. The present systematic review describes the current data reporting the nature and incidence of, and management and treatment options for, dermatologic toxicities occurring during anti-EGFR treatment of mCRC. A search of the National Library of Medicine PubMed database from January 1, 2009, to August 18, 2016, identified relevant reports discussing dermatologic toxicity management among patients with mCRC receiving anti-EGFR therapy. The studies were grouped by type and rated by level of evidence using the GRADE approach developed by the Agency for Healthcare Research and Quality. Overall, 269 reports were reviewed (nonrandomized trials, n = 120; randomized trials, n = 31; retrospective studies, n = 15; reviews, n = 39). Dermatologic toxicity of any grade occurs in most patients who receive anti-EGFR therapy; approximately 10% to 20% of patients experienced grade 3/4 toxicity. The most common dermatologic toxicities include papulopustular/acneiform rash, xerosis, and pruritus; however, nail changes, hair abnormalities, and ocular conditions also occur. Guidance for managing these toxicities includes the use of inexpensive emollient ointments and moisturizers, avoidance of sun exposure, avoidance of irritants, and the use of short showers. Several studies also found that preemptive treatment was more effective than reactive treatment at limiting the incidence and severity of skin toxicity. With appropriate treatment, the dermatologic toxicities associated with anti-EGFR monoclonal antibody therapy can be managed, minimizing patient discomfort and the need for therapy interruption and/or discontinuation. Additionally, preemptive treatment can reduce dermatologic toxicity severity, ultimately yielding better quality of life. PMID- 29576428 TI - c-MET Overexpression in Colorectal Cancer: A Poor Prognostic Factor for Survival. AB - INTRODUCTION: Increased mesenchymal-epithelial transition factor gene (c-MET) expression in several human malignancies is related to increased tumor progression and is a new potential drug target for several types of cancers. In the present study, we investigated the incidence of c-MET overexpression and its prognostic significance in patients with colorectal cancer (CRC). PATIENTS AND METHODS: We retrospectively reviewed the data from 255 stage IV CRC patients who had results from a c-MET immunohistochemical test at Samsung Medical Center. We explored the relationships between c-MET overexpression and clinicopathological features and survival. RESULTS: Primary tumor sites were 67 right-sided colon, 98 left-sided colon, and 90 rectum. Forty-two patients (16.7%) had poorly differentiated or mucinous carcinoma. Among the 255 patients, 39 (15.3%) exhibited c-MET overexpression. There was no significant difference in the prevalence of c-MET overexpression according to primary site, histologic differentiation, molecular markers, or metastatic sites. In a comparison of the tumor response to first-line chemotherapy according to the level of c-MET expression, we found no significant difference in either partial response or disease control rate. In the survival analysis, patients with c-MET overexpression had significantly shorter overall survival (39 vs. 27 months; P = .018) and progression-free survival (PFS) during bevacizumab treatment (10 vs. 7 months; P = .024). CONCLUSION: c-MET overexpression, which was detected in 39 CRC patients (15.3%) irrespective of primary sites or molecular markers, indicated a poor survival prognosis and predicted shorter PFS during bevacizumab treatment in patients with CRC. Further studies are warranted to elucidate the value of c-MET targeted therapy in CRC patients. PMID- 29576429 TI - Continuous Variation within Cell Types of the Nervous System. AB - The brain is an organ of immense complexity. Next-generation RNA sequencing (RNA seq) is becoming increasingly popular in the deconstruction of this complexity into distinct classes of 'cell types'. Notably, in addition to revealing the organization of this distinct cell-type landscape, the technology has also begun to illustrate that continuous variation can be found within narrowly defined cell types. Here we summarize the evidence for graded transcriptomic heterogeneity being present, widespread, and functionally relevant in the nervous system. We explain how these graded differences can map onto higher-order organizational features and how they may reframe existing interpretations of higher-order heterogeneity. Ultimately, a multimodal approach incorporating continuously variable cell types will facilitate an accurate reductionist interpretation of the nervous system. PMID- 29576430 TI - Erectile Dysfunction and Associated Risk Factors in Chinese Males of Infertile Couples. AB - BACKGROUND: Knowledge on the occurrence of erectile dysfunction (ED) and timely ovulatory intercourse failure (TOIF) in Chinese men of infertile couples is limited. AIM: To obtain representative estimates of ED and TOIF in Chinese men of infertile couples and to analyze potential risk factors associated with ED. METHODS: 4,299 Chinese men of infertile couples with an average age of 32.85 +/- 5.98 years were surveyed using the 5-item International Index of Erectile Function (IIEF-5) questionnaire for their ED occurrence. Multiple logistic regression analysis was used to disclose risk factors associated with ED. OUTCOMES: The occurrence of ED was 57.8% and that of TOIF was up to 26.2% in Chinese men of infertile couples. RESULTS: Based on IIEF-5 criteria, 34.9% of men had mild ED and only 2.6% had severe ED. Secondary infertility, infertility with known causes, and chronic prostatitis were significant risk factors associated with ED. TOIF was significantly higher (23.3%) in men of infertile couples with ED than in those without ED (8.6%), indicating that TOIF is likely a contributing factor to male infertility. CLINICAL IMPLICATIONS: Understanding the occurrence and types of ED and TOIF in men of infertile couples and their associated risk factors will help physicians treat clinical cases of male infertility more effectively. STRENGTHS AND LIMITATIONS: Large numbers of infertile outpatients from multiple hospital clinics across the country were included in this study. The concept of TOIF was raised for the 1st time and studied preliminarily in Chinese men of infertile couples. The lack of participants' psychological status, a control group of men of fertile couples, and measurement of testosterone levels was a limitation in this clinic-based study. CONCLUSION: The occurrence of ED was higher in Chinese men of infertile couples than in the general Chinese male population. Yang B, Xu P, Shi Y, et al.

AB - BACKGROUND: Sexual distress is an important component of sexual dysfunction and quality of life and many different measures have been developed for its assessment. AIM: To conduct a literature review of measures for assessing sexual distress and to list, compare, and highlight their characteristics and psychometric properties. METHODS: A systematic review was conducted using Scopus and PubMed databases to identify studies that developed and validated measures of sexual distress. The main characteristics and psychometric properties of each measure were extracted and examined. OUTCOMES: Psychometrically validated measures of sexual distress and a summary of relative strengths and limitations. RESULTS: We found 17 different measures for the assessment of sexual distress. 4 were standalone questionnaires and 13 were subscales included in questionnaires that assessed broader constructs. Although 5 measures were developed to assess sexual distress in the general population, most were developed and validated in very specific clinical groups. Most followed adequate steps in the development and validation process and have strong psychometric properties; however, several limitations were identified. CLINICAL TRANSLATION: This literature review offers researchers and clinicians a list of sexual distress measures and relevant characteristics that can be used to select the best assessment tool for their objectives. STRENGTHS AND LIMITATIONS: A thorough search procedure was used; however, there is still a chance that relevant articles might have been missed owing to our search methodology and inclusion criteria. CONCLUSION: This is a novel and state-of-the-art review of assessment tools for sexual distress that includes valuable information measure selection in the study of sexual distress and sexual dysfunction.

PMID- 29576433 TI - Cognitive and clinical variables associated with interictal dysphoric disorder in patients with epilepsy. AB - PURPOSE: The relationship between interictal dysphoric disorder (IDD) and cognitive impairment in adult patients with epilepsy (PWE) is poorly studied. METHODS: The Interictal Dysphoric Disorder Inventory (IDDI) with cognitive and clinical aspects was compared with Quality of Life in Epilepsy Inventory (QOLIE 31) and Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) scores of 117 PWE at significance level p<0.05. RESULTS: Interictal dysphoric disorder occurred in 25 (21.4%) PWE, and it was significantly associated with the presence of psychiatric disorders (PD) (alpha2; p=0.007), presence of major depressive episodes (p=0.03), lower educational level, older individuals, and those with a lower performance in the category fluency test (VF) (9.7+/-5.1 vs. 12.2+/-4.2; t test; p=0.037). There was a negative correlation between QOLIE-31 and IDD. The predictive factors for the occurrence of IDD were the presence of PD (p=0.014) and lower performance in the VF (p=0.013). CONCLUSION: The occurrence of IDD was high. Interictal dysphoric disorder was found in different epileptic syndromes, and it was associated with the presence of PD, depressive episodes, lower performance in VF, and lower quality of life (QoL). PMID- 29576434 TI - Surgical versus medical treatment of drug-resistant epilepsy: A systematic review and meta-analysis. AB - OBJECTIVE: Surgery and drug therapy are the two main treatments for refractory epilepsy. However, to date, there has not been an adequate comparison of the outcomes of these two treatments. This systematic review compared the overall outcome of surgery and medical treatment in patients with drug-resistant epilepsy. METHODS: Articles published in Embase, Medline, Pubmed, and the Cochrane library were searched from their inception until June 2016. RESULTS: Twenty of the eighty-one (24.7%) full-text articles reviewed fulfilled the eligibility criteria and were included in the meta-analysis. Of 1800 patients with drug-resistant epilepsy, 526 of 923 patients (57.0%) in the surgery group were seizure-free compared with 134 of 877 patients (15.3%) in the medical treatment group (19 studies, risk ratio (RR)=3.72, 95% confidence interval (CI) [2.75-5.03]; P<0.00001, I2=53%). In addition, more patients were off antiepileptic drugs (AEDs) in the surgical group (3 studies, n=438, RR=4.76, 95% CI [2.21, 10.28], P<0.0001, I2=0%). Although different studies used different questionnaires to assess patient quality of life (QOL) in both treatment groups, the overall postintervention QOL scores were higher in the surgery than in the medical treatment group, by SMD (6 studies, n=459, SMD=0.61, 95% CI [0.23, 0.98], P=0.002, I2=66%). CONCLUSION: As the complications of interventions, declines in memory, and word recall/naming were not assessed in the meta-analysis, the conclusions are limited to seizure-free, AED use, and QOL. The current evidence indicate that compared with medical treatment, surgery is more likely to achieve seizure-free, off AEDs, and better QOL.

AB - : Dysphotopsia affects a significant number of patients, particularly after visual correction with multifocal optical designs. PURPOSE: Evaluate light distortion (LD) in two modalities of contact lens (CL) wear: multifocal (MF) and monofocal (MV). METHODS: This was a randomized, double-masked, crossover study involving 20 presbyopic patients. Patients were randomized first into either MF or MV for 15 days of use with a 1 week wash-out period between each lens type. The LD was evaluated with the Light Distortion Analyzer (LDA, University of Minho) under monocular and binocular conditions. The light distortion index (LDI, %), among other parameters were analyzed. Subjective quality of vision was assessed with the Quality of Vision (QoV). RESULTS: The LD showed an increase in all parameters in both CL modalities being significant for MV in the non-dominant eye (p < 0.030, for all LD parameters). For the MF, there was also a significant increase in LDI (p = 0.016) and in BFCrad (p = 0.022) in the non-dominant eye. After 15 days of MF lens wear, there was a significant decrease in all LD parameters (p < 0.002) in the dominant eye. Binocularly, a significant improvement from 1 to 15 days was observed for LDI (p = 0.009) and BFCrad (p = 0.0013) with MF. The QoV questionnaire showed no significant changes with neither CL. CONCLUSIONS: Adaptation to light disturbances induced by MF CL is more effective compared to MV. Practitioners will have greater success if they prepare their patients for the adaptation required as their vision will get better and have less of an issue with light disturbance. PMID- 29576437 TI - Enterochromaffin 5-HT cells - A major target for GLP-1 and gut microbial metabolites. AB - OBJECTIVES: 5-HT storing enterochromaffin (EC) cells are believed to respond to nutrient and gut microbial components, and 5-HT receptor-expressing afferent vagal neurons have been described to be the major sensors of nutrients in the GI tract. However, the molecular mechanism through which EC cells sense nutrients and gut microbiota is still unclear. METHODS AND RESULTS: TPH1, the 5-HT generating enzyme, and chromogranin A, an acidic protein responsible for secretory granule storage of 5-HT, were highly enriched in FACS-purified EC cells from both small intestine and colon using a 5-HT antibody-based method. Surprisingly, EC cells from the small intestine did not express GPCR sensors for lipid and protein metabolites, such as FFAR1, GPR119, GPBAR1 (TGR5), CaSR, and GPR142, in contrast to the neighboring GLP-1 storing enteroendocrine cell. However, the GLP-1 receptor was particularly highly expressed and enriched in EC cells as judged both by qPCR and by immunohistochemistry using a receptor antibody. GLP-1 receptor agonists robustly stimulated 5-HT secretion from intestinal preparations using both HPLC and a specific amperometric method. Colonic EC cells expressed many different types of known and potential GPCR sensors of microbial metabolites including three receptors for SCFAs, i.e. FFAR2, OLF78, and OLF558 and receptors for aromatic acids, GPR35; secondary bile acids GPBAR1; and acyl-amides and lactate, GPR132. CONCLUSION: Nutrient metabolites apparently do not stimulate EC cells of the small intestine directly but through a paracrine mechanism involving GLP-1 secreted from neighboring enteroendocrine cells. In contrast, colonic EC cells are able to sense a multitude of different metabolites generated by the gut microbiota as well as gut hormones, including GLP-1. PMID- 29576439 TI - LRRK2 protective haplotype and full sequencing study in REM sleep behavior disorder. AB - BACKGROUND: Individuals with rapid eye movement (REM)-sleep behavior disorder (RBD) are likely to progress to synucleinopathies, mainly Parkinson's disease (PD), dementia with Lewy-bodies (DLB) and multiple system atrophy (MSA). The genetics of RBD only partially overlaps with PD and DLB, and the role of LRRK2 variants in risk for RBD is still not clear. METHODS: The full coding sequence, exon-intron boundaries and 5' and 3' untranslated regions of LRRK2 were sequenced using targeted next-generation sequencing. A total of 350 RBD patients and 869 controls were sequenced, and regression and burden models were used to examine the association between LRRK2 variants and RBD. RESULTS: No pathogenic mutations that are known to cause PD were identified in RBD patients. The p.N551K-p.R1398H p.K1423K haplotype was associated with a reduced risk for RBD (OR = 0.66, 95% CI 0.44-0.98, p = 0.0055 for the tagging p.N551K substitution). A common variant, p.S1647T, was nominally associated with risk for RBD (OR = 1.28, 95% CI 1.05 1.56, p = 0.029). Burden analysis identified associations with domains and exons that were derived by the variants of the protective haplotype, and no burden of other rare variants was identified. CONCLUSIONS: Carriers of the LRRK2 p.N551K p.R1398H-p.K1423K haplotype have a reduced risk for developing RBD, yet PD causing mutations probably have minor or no role in RBD. Additional work is needed to confirm these results and to identify the mechanism associated with reduced risk for RBD. PMID- 29576440 TI - Evolution of dietary preferences and the innate urge to heal: Drug discovery lessons from Ayurveda. AB - Highly specialized and functionally integrated cognitive systems facilitate hedonistic and healthy food preferences. Guided by survival needs, flavor preferences not only select safe, nutritious dietary components, but also those with negligible calorific value but significant health benefits, for example, spices. Feeding behavior, both innate and acquired, is guided not only by taste receptors on the tongue but also visceral organs. The gustatory cortex receives information from all senses, not just taste, suggesting multiple checkpoints in predicting and evaluating healthy foods. Ayurvedic interpretation of 'rasa' as chemistry is compatible with medicinal value of diets because, taste and odor are chemosensory perceptions. As flavor and taste are linked to the chemical structure of compounds, taste might offer clues about pharmacological activity. Ayurvedic idea of vipaka, or post digestive perception of taste, recognizes the extended role of taste receptors beyond the tongue and stretching into the viscera. Ayurvedic wisdom is consistent with evolutionary guideposts that suggest three successive stages of nutritional appraisal: before, during, and after ingesting food. While olfaction induces affinity or revulsion even before ingestion, gustatory receptors on the tongue evaluates nutritional value upon contact, and the chemoreceptors in the deeper metabolic systems probably pronounce the final verdict on the nutritive and health benefits of ingested substances. Alliesthesia, neophobia, and the extreme variation in human T2R genes (coding for bitterness receptors) illustrate the importance of adaptive learning of dietary preferences. These evolutionary clues are compatible with the Ayurvedic principle of 'rasa', in facilitating the process of drug discovery. PMID- 29576441 TI - Low-Intensity Shockwave Therapy for Erectile Dysfunction. AB - BACKGROUND: Vasculogenic erectile dysfunction (ED) is one of the leading causes of male sexual dysfunction. In the past decade, multiple studies have examined the use of low-intensity extracorporeal shockwave therapy (Li-ESWT) for the treatment of ED. AIM: Investigate the efficacy of Li-ESWT for the treatment of ED. METHODS: We reviewed the published literature, including randomized controlled trials (RCTs), meta-analyses, and select single-arm studies on the use of Li-ESWT for the treatment of ED. OUTCOMES: Changes in International Index of Erectile Function scores were evaluated in patients undergoing Li-ESWT. RESULTS: There is no consensus from RCTs on the efficacy of Li-ESWT for the treatment of ED. Published meta-analyses have shown significant improvement in International Index of Erectile Function-erectile function domain scores in men undergoing Li ESWT, especially when compared to men receiving sham treatment. However, differences in treatment protocols limit the generalizability of these findings. Li-ESWT may be more beneficial in cases of mild ED or when combined with phosphodiesterase type 5 inhibitors in men with moderate to severe ED. The role of Li-ESWT in the treatment of non-vasculogenic ED remains poorly defined. CONCLUSIONS: Li-ESWT could be beneficial in specific sub-sets of men with vasculogenic ED. However, future RCTs should attempt to optimize treatment protocols and have more stringent inclusion criteria to confirm these findings. Rizk PJ, Krieger JR, Kohn TP, et al.

PMID- 29576443 TI - Modifiable risk factors for acute skin toxicity in adjuvant breast radiotherapy: Dosimetric analysis and review of the literature. AB - Acute skin toxicity in adjuvant breast radiation can be reduced with modern radiotherapy (RT) techniques. However, having reviewed the literature, we found no dosimetric constraint for acute skin toxicity that would be applicable to modern RT planning. This study aimed to identify dosimetric factors that are associated with higher rates of acute skin toxicity. A retrospective review was carried out including women who received adjuvant forward-planned intensity modulated radiotherapy (IMRT) after breast-conserving surgery. Acute skin toxicity grade was prospectively recorded. A total of 131 patients were analyzed. On multivariate analysis, the V105% > 30 cc (p = 0.013) and the use of conventional fractionation (CF) (p = 0.001) were statistically significant for acute skin toxicity. On literature review, current quantitative dosimetric parameters that have shown statistical significance include a V107% > 3 cc in hypofractionation (HF), V107% > 9 cc in CF, treated volume 110% > 5.13%, and V107% > 28.6%. There is little evidence on the predictive value of clinically applicable dosimetric factors in acute skin toxicity. Given the recent improvements in RT planning, we would consider a V107% or a V110% too high a dosimetric value to be useful for the majority of patients. We have shown that a V105% of greater than 30 cc is significantly associated with acute skin toxicity, controlling for other variables. We suggest that this is currently the most useful modifiable parameter available to reduce skin toxicity and is applicable to modern RT planning. We also suggest that consideration be given to hypofractionated schedules to further reduce acute skin toxicity. PMID- 29576442 TI - Effect Size in Efficacy Trials of Women With Decreased Sexual Desire. AB - BACKGROUND: Regarding hypoactive sexual desire disorder (HSDD) in women, some reviewers judge the effect size small for medications vs placebo, but substantial for cognitive behavior therapy (CBT) or mindfulness meditation training (MMT) vs wait list. However, we lack comparisons of the effect sizes for the active intervention itself, for the control treatment, and for the differential between the two. AIM: For efficacy trials of HSDD in women, compare effect sizes for medications (testosterone/testosterone transdermal system, flibanserin, and bremelanotide) and placebo vs effect sizes for psychotherapy and wait-list control. METHODS: We conducted a literature search for mean changes and SD on main measures of sexual desire and associated distress in trials of medications, CBT, or MMT. Effect size was used as it measures the magnitude of the intervention without confounding by sample size. OUTCOMES: Cohen d was used to determine effect sizes. RESULTS: For medications, mean (SD) effect size was 1.0 (0.34); for CBT and MMT, 1.0 (0.36); for placebo, 0.55 (0.16); and for wait list, 0.05 (0.26). CLINICAL TRANSLATION: Recommendations of psychotherapy over medication for treatment of HSDD are premature and not supported by data on effect sizes. Active participation in treatment conveys considerable non-specific benefits. Caregivers should attend to biological and psychosocial elements, and patient preference, to optimize response. CONCLUSIONS: Few clinical trials of psychotherapies were substantial in size or utilized adequate control paradigms. Medications and psychotherapies had similar, large effect sizes. Effect size of placebo was moderate. Effect size of wait-list control was very small, about one quarter that of placebo. Thus, a substantial non-specific therapeutic effect is associated with receiving placebo plus active care and evaluation. The difference in effect size between placebo and wait-list controls distorts the value of the subtraction of effect of the control paradigms to estimate intervention effectiveness.

PMID- 29576444 TI - Biparametric Prostate Imaging Reporting and Data System version2 and International Society of Urological Pathology Grade Predict Biochemical Recurrence after Radical Prostatectomy. AB - BACKGROUND: We retrospectively assessed the clinical significance of the Prostate Imaging Reporting and Data System (PI-RADS), version 2, criteria based on biparametric magnetic resonance imaging (bp-MRI), together with the International Society of Urological Pathology (ISUP) grade, for predicting biochemical recurrence (BCR) after radical prostatectomy. MATERIALS AND METHODS: The data from 126 patients who had undergone radical prostatectomy were retrospectively analyzed. The prognostic significance of the PI-RADS v2 score based on bp-MRI was assessed with other clinical factors, including the ISUP grade. We defined a positive PI-RADS and ISUP score as >= 4 and >= 3, respectively. Statistical analysis was performed using Cox proportional hazard models, logistic regression analysis, and the Kaplan-Meier method. RESULTS: The median age and median prostate-specific antigen level were 66 years and 7.96 ng/mL, respectively. The number of positive PI-RADS scores was 106 (84.1%) and the number of positive ISUP grade scores was 71 (56.3%). PI-RADS >= 4 (P = .0031) and ISUP >= 3 (P = .070) were the 2 independent prognostic factors predictive of BCR. A positive PI-RADS score was related to tumor volume (P = .014), and a positive ISUP score was related to prostate-specific antigen level (P = .043), extraprostatic extension (P = .029), and Gleason upgrading (P < .0001). After stratifying patients into risk groups according to PI-RADS and ISUP positivity, the poor-risk group (PI RADS and ISUP grade positive) showed significantly worse BCR-free survival compared with that of the favorable- and intermediate-risk groups (P < .0001), with a median survival difference of 21 months. CONCLUSION: Biparametric PI-RADS v2 and ISUP grade criteria predicted for BCR after radical prostatectomy. PI-RADS v2 combined with the ISUP grade might be helpful in choosing the treatment modality of patients with localized prostate cancer. PMID- 29576445 TI - Feasibility of Cisplatin-Based Neoadjuvant Chemotherapy in Muscle-Invasive Bladder Cancer Patients With Diminished Renal Function. AB - BACKGROUND: Cisplatin-based neoadjuvant chemotherapy (NAC) before radical cystectomy is the standard of care in muscle-invasive bladder cancer. There are limited data regarding chemotherapy tolerability and outcomes for patients with low glomerular filtration rate (GFR) who receive cisplatin-based NAC. PATIENTS AND METHODS: A retrospective analysis of patients who received cisplatin-based NAC at Cleveland Clinic (2005-2016) was undertaken. Patients with pre-NAC GFR < 60 mL/min by either Cockcroft-Gault (CG) or Modification of Diet in Renal Disease (MDRD) formula were compared to patients with GFR >= 60 mL/min for NAC tolerability, pathologic complete and partial response (pPR), and the ability to undergo radical cystectomy. RESULTS: Thirty patients with low GFR (34-59 mL/min) and 94 patients with normal GFR (>= 60 mL/min) were identified. Low GFR patients were older (median, 71 vs. 65 years), but other demographic and transurethral resection of bladder tumor characteristics were comparable. Low GFR patients more frequently had early NAC discontinuation (30% vs. 13%), NAC modifications (delays, dose reduction, or discontinuation, 66% vs. 40%), and cisplatin-based NAC administered in split doses (37% vs. 16%). No differences in NAC tolerability or outcomes were noted among low GFR patients receiving split-dose versus standard regimens. No differences were noted between low and normal GFR patients in NAC cycles (median, 3 for each), cystectomy rates (93% for each), time to cystectomy, and GFR change from baseline to after NAC. Pathologic complete response was higher among normal GFR patients (24% vs. 14%). CONCLUSION: Patients with low GFR had more NAC discontinuations and modifications, but most completed planned NAC cycles. For carefully selected patients with GFR < 60 mL/min, cisplatin-based NAC remains a treatment option. PMID- 29576446 TI - Online Sales of Marijuana: An Unrecognized Public Health Dilemma. PMID- 29576447 TI - [Telephone support for breastfeeding by primary care: a randomised multicentre trial]. AB - OBJECTIVE: To evaluate a telephone support programme for mothers who breastfeed for the first 6 months. METHODS: A randomised unmasked clinical trial was conducted in 5 urban Primary Care centres that included mothers with healthy newborns who were breastfeeding exclusively (EBF) or partially (PBF). The control group received the usual care. The intervention group also received telephone support for breastfeeding on a weekly basis for the first 2months and then every 2weeks until the sixth month. The type of breastfeeding was recorded in the usual check-up visit (1, 2, 4 and 6 months). RESULTS: The study included 193 patients in the intervention group, and 187 in a control group. The greatest increase in the percentage of EBF was observed at 6 months: 21.4% in the control group compared to 30.1% in the intervention group. However, in the adjusted odds ratios analysis, confidence intervals did not show statistical significance. The odds ratio at 1 month, 2 months, 4 months, and 6 months for EBF were 1.45 (0.91-2.31), 1.35 (0.87-2.08), 1.21 (0.80-1.81), and 1.58 (0.99-2.53), respectively. The odds ratio in the same age groups for any type of breastfeeding (EBF + PBF) were 1.65 (0.39-7.00), 2.08 (0.94-4.61), 1.37 (0.79-2.38), and 1.60 (0.98-2.61), respectively. CONCLUSIONS: Telephone intervention was not effective enough to generalise it. PMID- 29576448 TI - Dual inhibition of PI3K/mTOR signaling in chemoresistant AML primary cells. AB - A main cause of treatment failure for AML patients is resistance to chemotherapy. Survival of AML cells may depend on mechanisms that elude conventional drugs action and/or on the presence of leukemia initiating cells at diagnosis, and their persistence after therapy. MDR1 gene is an ATP-dependent drug efflux pump known to be a risk factor for the emergence of resistance, when combined to unstable cytogenetic profile of AML patients. In the present study, we analyzed the sensitivity to conventional chemotherapeutic drugs of 26 samples of primary blasts collected from AML patients at diagnosis. Detection of cell viability and apoptosis allowed to identify two group of samples, one resistant and one sensitive to in vitro treatment. The cells were then analyzed for the presence and the activity of P-glycoprotein. A comparative analysis showed that resistant samples exhibited a high level of MDR1 mRNA as well as of P-glycoprotein content and activity. Moreover, they also displayed high PI3K signaling. Therefore, we checked whether the association with signaling inhibitors might resensitize resistant samples to chemo-drugs. The combination showed a very potent cytotoxic effect, possibly through down modulation of MDR1, which was maintained also when primary blasts were co-cultured with human stromal cells. Remarkably, dual PI3K/mTOR inactivation was cytotoxic also to leukemia initiating cells. All together, our findings indicate that signaling activation profiling associated to gene expression can be very useful to stratify patients and improve therapy. PMID- 29576449 TI - Expanding Actin Rings Zipper the Mouse Embryo for Blastocyst Formation. AB - Transformation from morula to blastocyst is a defining event of preimplantation embryo development. During this transition, the embryo must establish a paracellular permeability barrier to enable expansion of the blastocyst cavity. Here, using live imaging of mouse embryos, we reveal an actin-zippering mechanism driving this embryo sealing. Preceding blastocyst stage, a cortical F-actin ring assembles at the apical pole of the embryo's outer cells. The ring structure forms when cortical actin flows encounter a network of polar microtubules that exclude F-actin. Unlike stereotypical actin rings, the actin rings of the mouse embryo are not contractile, but instead, they expand to the cell-cell junctions. Here, they couple to the junctions by recruiting and stabilizing adherens and tight junction components. Coupling of the actin rings triggers localized myosin II accumulation, and it initiates a tension-dependent zippering mechanism along the junctions that is required to seal the embryo for blastocyst formation. PMID- 29576450 TI - Common PIEZO1 Allele in African Populations Causes RBC Dehydration and Attenuates Plasmodium Infection. AB - Hereditary xerocytosis is thought to be a rare genetic condition characterized by red blood cell (RBC) dehydration with mild hemolysis. RBC dehydration is linked to reduced Plasmodium infection in vitro; however, the role of RBC dehydration in protection against malaria in vivo is unknown. Most cases of hereditary xerocytosis are associated with gain-of-function mutations in PIEZO1, a mechanically activated ion channel. We engineered a mouse model of hereditary xerocytosis and show that Plasmodium infection fails to cause experimental cerebral malaria in these mice due to the action of Piezo1 in RBCs and in T cells. Remarkably, we identified a novel human gain-of-function PIEZO1 allele, E756del, present in a third of the African population. RBCs from individuals carrying this allele are dehydrated and display reduced Plasmodium infection in vitro. The existence of a gain-of-function PIEZO1 at such high frequencies is surprising and suggests an association with malaria resistance. PMID- 29576451 TI - IRF8 Regulates Transcription of Naips for NLRC4 Inflammasome Activation. AB - Inflammasome activation is critical for host defenses against various microbial infections. Activation of the NLRC4 inflammasome requires detection of flagellin or type III secretion system (T3SS) components by NLR family apoptosis inhibitory proteins (NAIPs); yet how this pathway is regulated is unknown. Here, we found that interferon regulatory factor 8 (IRF8) is required for optimal activation of the NLRC4 inflammasome in bone-marrow-derived macrophages infected with Salmonella Typhimurium, Burkholderia thailandensis, or Pseudomonas aeruginosa but is dispensable for activation of the canonical and non-canonical NLRP3, AIM2, and Pyrin inflammasomes. IRF8 governs the transcription of Naips to allow detection of flagellin or T3SS proteins to mediate NLRC4 inflammasome activation. Furthermore, we found that IRF8 confers protection against bacterial infection in vivo, owing to its role in inflammasome-dependent cytokine production and pyroptosis. Altogether, our findings suggest that IRF8 is a critical regulator of NAIPs and NLRC4 inflammasome activation for defense against bacterial infection. PMID- 29576453 TI - Flavin Monooxygenase-Generated N-Hydroxypipecolic Acid Is a Critical Element of Plant Systemic Immunity. AB - Following a previous microbial inoculation, plants can induce broad-spectrum immunity to pathogen infection, a phenomenon known as systemic acquired resistance (SAR). SAR establishment in Arabidopsis thaliana is regulated by the Lys catabolite pipecolic acid (Pip) and flavin-dependent-monooxygenase1 (FMO1). Here, we show that elevated Pip is sufficient to induce an FMO1-dependent transcriptional reprogramming of leaves that is reminiscent of SAR. In planta and in vitro analyses demonstrate that FMO1 functions as a pipecolate N-hydroxylase, catalyzing the biochemical conversion of Pip to N-hydroxypipecolic acid (NHP). NHP systemically accumulates in plants after microbial attack. When exogenously applied, it overrides the defect of NHP-deficient fmo1 in acquired resistance and acts as a potent inducer of plant immunity to bacterial and oomycete infection. Our work has identified a pathogen-inducible L-Lys catabolic pathway in plants that generates the N-hydroxylated amino acid NHP as a critical regulator of systemic acquired resistance to pathogen infection. PMID- 29576454 TI - Profound Tissue Specificity in Proliferation Control Underlies Cancer Drivers and Aneuploidy Patterns. AB - Genomics has provided a detailed structural description of the cancer genome. Identifying oncogenic drivers that work primarily through dosage changes is a current challenge. Unrestrained proliferation is a critical hallmark of cancer. We constructed modular, barcoded libraries of human open reading frames (ORFs) and performed screens for proliferation regulators in multiple cell types. Approximately 10% of genes regulate proliferation, with most performing in an unexpectedly highly tissue-specific manner. Proliferation drivers in a given cell type showed specific enrichment in somatic copy number changes (SCNAs) from cognate tumors and helped predict aneuploidy patterns in those tumors, implying that tissue-type-specific genetic network architectures underlie SCNA and driver selection in different cancers. In vivo screening confirmed these results. We report a substantial contribution to the catalog of SCNA-associated cancer drivers, identifying 147 amplified and 107 deleted genes as potential drivers, and derive insights about the genetic network architecture of aneuploidy in tumors. PMID- 29576452 TI - iPSCs from a Hibernator Provide a Platform for Studying Cold Adaptation and Its Potential Medical Applications. AB - Hibernating mammals survive hypothermia (<10 degrees C) without injury, a remarkable feat of cellular preservation that bears significance for potential medical applications. However, mechanisms imparting cold resistance, such as cytoskeleton stability, remain elusive. Using the first iPSC line from a hibernating mammal (13-lined ground squirrel), we uncovered cellular pathways critical for cold tolerance. Comparison between human and ground squirrel iPSC derived neurons revealed differential mitochondrial and protein quality control responses to cold. In human iPSC-neurons, cold triggered mitochondrial stress, resulting in reactive oxygen species overproduction and lysosomal membrane permeabilization, contributing to microtubule destruction. Manipulations of these pathways endowed microtubule cold stability upon human iPSC-neurons and rat (a non-hibernator) retina, preserving its light responsiveness after prolonged cold exposure. Furthermore, these treatments significantly improved microtubule integrity in cold-stored kidneys, demonstrating the potential for prolonging shelf-life of organ transplants. Thus, ground squirrel iPSCs offer a unique platform for bringing cold-adaptive strategies from hibernators to humans in clinical applications. VIDEO ABSTRACT. PMID- 29576455 TI - Development of Concurrent Retinotopic Maps in the Fly Motion Detection Circuit. AB - Understanding how complex brain wiring is produced during development is a daunting challenge. In Drosophila, information from 800 retinal ommatidia is processed in distinct brain neuropiles, each subdivided into 800 matching retinotopic columns. The lobula plate comprises four T4 and four T5 neuronal subtypes. T4 neurons respond to bright edge motion, whereas T5 neurons respond to dark edge motion. Each is tuned to motion in one of the four cardinal directions, effectively establishing eight concurrent retinotopic maps to support wide-field motion. We discovered a mode of neurogenesis where two sequential Notch-dependent divisions of either a horizontal or a vertical progenitor produce matching sets of two T4 and two T5 neurons retinotopically coincident with pairwise opposite direction selectivity. We show that retinotopy is an emergent characteristic of this neurogenic program and derives directly from neuronal birth order. Our work illustrates how simple developmental rules can implement complex neural organization. PMID- 29576457 TI - The effect of template-based sequential (TBS) coding on an NHS plastic surgical practice. AB - INTRODUCTION: Clinical coding is often a mystery to us surgeons, but in actuality, it has a huge bearing on the financial sustainability of our services. Given the rapid innovations in plastic surgical procedures, clinical coders often struggle to decipher the extent of surgery. Meeting midway is the way forward here. METHODS: In a prospective audit over a six-month period, we analysed data from 2586 patients in our practice: a combination of general plastic surgery and specialist facial reanimation services. This involved comparing data from the first three months where coding was performed by clinical coders based on operating notes per se (phase I) and the subsequent three months when the operating surgeon filled in the OPCS 4.7 (version 2014) codes at the time of completing the operating notes; the clinical coders then vetted this information (phase II) as part of a sequential TBS coding system. RESULTS: In terms of outpatient income, there was a 3% increase in facial palsy income and 6% increase in general plastic services, but the most significant improvement was in terms of procedural income per case. General plastic surgery cases saw an increase of 49%, while facial palsy income increased by 58% over the same period. Greater insight into OPCS and HRG codes also allowed for the calculation of the actual tariffs for specific procedures. CONCLUSIONS: Having the operating surgeon as the primary coder, using a template, with subsequent vetting by the clinical coders, improves data capture, and this in turn increases income. Future recommendations include the use of proforma-based operating notes for workhorse procedures. PMID- 29576456 TI - Phase Transitions in the Assembly and Function of Human miRISC. AB - miRISC is a multi-protein assembly that uses microRNAs (miRNAs) to identify mRNAs targeted for repression. Dozens of miRISC-associated proteins have been identified, and interactions between many factors have been examined in detail. However, the physical nature of the complex remains unknown. Here, we show that two core protein components of human miRISC, Argonaute2 (Ago2) and TNRC6B, condense into phase-separated droplets in vitro and in live cells. Phase separation is promoted by multivalent interactions between the glycine/tryptophan (GW)-rich domain of TNRC6B and three evenly spaced tryptophan-binding pockets in the Ago2 PIWI domain. miRISC droplets formed in vitro recruit deadenylation factors and sequester target RNAs from the bulk solution. The condensation of miRISC is accompanied by accelerated deadenylation of target RNAs bound to Ago2. The combined results may explain how miRISC silences mRNAs of varying size and structure and provide experimental evidence that protein-mediated phase separation can facilitate an RNA processing reaction. PMID- 29576458 TI - Encapsulation of mesenchymal stem cells in chitosan/beta-glycerophosphate hydrogel for seeding on a novel calcium phosphate cement scaffold. AB - Due to its moldability, biocompatibility, osteoconductivity and resorbability, calcium phosphate cement (CPC) is a highly promising scaffold material for orthopedic applications. However, pH changes and ionic activity during the CPC setting reaction may adversely affect cells seeded directly on CPC. Moreover, a lack of macropores in CPC limits ingrowth of new bone. The objectives of this study were to prepare macroporous CPC scaffolds via porogen leaching, using mannitol crystals as the porogen and to evaluate the in vitro proliferation and osteogenic differentiation of mesenchymal stem cells (MSCs) encapsulated in chitosan/beta-glycerophosphate (C/GP) hydrogel prior to exposure to the novel CPC scaffold. MSCs were found to be adhered to the surfaces of CPC macropores via scanning electron microscopy. The viability and osteogenic differentiation of MSCs in C/GP hydrogel with or without exposure to CPC constructs containing mannitol crystals indicated that coating with C/GP hydrogel protected the cells during cement mixing and setting. In conclusion, novel, macroporous CPC scaffolds were prepared, and our data indicate that a hydrogel encapsulation-based strategy can be used to protect cells during scaffold formation. Thus, the MSC-laden CPC scaffolds show promise for the delivery of stem cells to promote bone regeneration. PMID- 29576459 TI - Simple and efficient thermal calibration for MEMS gyroscopes. AB - Gyroscopes are now becoming one of the most sold MEMS sensors, given that the many applications that require their use are booming. In the medical field, gyroscopes can be found in Inertial Measurement Units used for the development of clinical tools that are dedicated to human-movement monitoring. However, MEMS gyroscopes are known to suffer from a drift phenomenon, which is mainly due to temperature variations. This drift dramatically affects measurement capability, especially that of cheap MEMs gyroscopes. Calibration is therefore a key factor in achieving accurate measurements. However, traditional calibration procedures are often complex and require costly equipment. This paper therefore proposes an easy protocol for performing a thermal gyroscope calibration. In this protocol, accuracy over the angular velocity is evaluated by referring to an optoelectronic measurement, and is compared with the traditional calibration performed by the manufacturer. The RMSE between the reference angular velocity and that obtained with the proposed calibration was of 0.7 degrees /s, which was slightly smaller than the RMSE of 1.1 degrees /s achieved by the manufacturer's calibration. An analysis of uncertainty propagation shows that offset variability is the major source of error over the computed rate of rotation from the tested sensors, since it accounts for 97% of the error. It can be concluded that the proposed simple calibration method leads to a similar degree of accuracy as that achieved by the manufacturer's procedure. PMID- 29576460 TI - Shape-memory-alloy-based smart knee spacer for total knee arthroplasty: 3D CAD modelling and a computational study. AB - This study introduced a shape memory alloy (SMA)-based smart knee spacer for total knee arthroplasty (TKA). Subsequently, a 3D CAD model of a smart tibial component of TKA was designed in Solidworks software, and verified using a finite element analysis in ANSYS Workbench. The two major properties of the SMA (NiTi), the pseudoelasticity (PE) and shape memory effect (SME), were exploited, modelled, and analysed for a TKA application. The effectiveness of the proposed model was verified in ANSYS Workbench through the finite element analysis (FEA) of the maximum deformation and equivalent (von Mises) stress distribution. The proposed model was also compared with a polymethylmethacrylate (PMMA)-based spacer for the upper portion of the tibial component for three subjects with body mass index (BMI) of 23.88, 31.09, and 38.39. The proposed SMA -based smart knee spacer contained 96.66978% less deformation with a standard deviation of 0.01738 than that of the corresponding PMMA based counterpart for the same load and flexion angle. Based on the maximum deformation analysis, the PMMA-based spacer had 30 times more permanent deformation than that of the proposed SMA-based spacer for the same load and flexion angle. The SME property of the lower portion of the tibial component for fixation of the spacer at its position was verified by an FEA in ANSYS. Wherein, a strain life-based fatigue analysis was performed and tested for the PE and SME built spacers through the FEA. Therefore, the SMA based smart knee spacer eliminated the drawbacks of the PMMA-based spacer, including spacer fracture, loosening, dislocation, tilting or translation, and knee subluxation. PMID- 29576461 TI - A patient specific finite element simulation of intramedullary nailing to predict the displacement of the distal locking hole. AB - Distal locking is a challenging subtask of intramedullary nailing fracture fixation due to the nail deformation that makes the proximally mounted targeting systems ineffective. A patient specific finite element model was developed, based on the QCT data of a cadaveric femur, to predict the position of the distal hole of the nail postoperatively. The mechanical interactions of femur and nail (of two sizes) during nail insertion was simulated using ABAQUS in two steps of dynamic pushing and static equilibrium, for the intact and distally fractured bone. Experiments were also performed on the same specimen to validate the simulation results. A good agreement was found between the model predictions and the experimental observations. There was a three-point contact pattern between the nail and medullary canal, only on the proximal fragment of the fractured bone. The nail deflection was much larger in the sagittal plane and increased for the larger diameter nail, as well as for more distally fractured or intact femur. The altered position of the distal hole was predicted by the model with an acceptable error (mean: 0.95; max: 1.5 mm, in different tests) to be used as the compensatory information for fine tuning of proximally mounted targeting systems. PMID- 29576462 TI - Laparoscopic surgery in the treatment of stage I adult granulosa cells tumors of the ovary: Results from the MITO-9 study. AB - OBJECTIVE: Surgery represents the mainstay of treatment of stage I adult type granulosa cell tumors of the ovary (AGCTs). Because of the rarity and indolent course of the disease, no prospective trials are available. Open surgery has long been considered the traditional approach; oncological safety of laparoscopy is only supported by small series or case reports. The aim of this study was to compare the oncological outcomes between laparoscopic and open surgery in stage I AGCTs treated within the MITO (Multicenter Italian Trials in Ovarian cancer) Group. METHODS: Data from patients with stage I AGCTs were retrospectively collected. Clinicopathological features were evaluated for association with relapse and death. Survival curves were calculated using the Kaplan-Meier method and compared with the log-rank test. The role of clinicopathological variables as prognostic factors for survival was evaluated using Cox's regression model. RESULTS: 223 patients were identified. Stage 1A, 1B and 1C were 61.5%, 1.3% and 29.6% respectively. 7.6% were apparently stage I. Surgical approach was laparoscopic for 93 patients (41.7%) and open for 130 (58.3%). 5-years DFS was 84% and 82%, 10-years DFS was 68% and 64% for the laparoscopic and open-group (p = 0.6).5-years OS was 100% and 99%, 10 years OS was 98% and 97% for the laparoscopic and open-surgery group (p = 0.8). At multivariate analyses stage IC, incomplete staging, site of primary surgery retained significant prognostic value. CONCLUSION: The present study suggests that surgical route does not affect the oncological safety of patients with stage I AGCTs, with comparable outcomes between laparoscopic and open approach.

This study aimed to identify risk factors for appendiceal, colon and rectal PM. METHODS: Data were retrieved from the Swedish Colorectal Cancer Registry for all patients undergoing bowel resection of appendiceal and colorectal tumours, in Sweden, 2007-2015. Risk factors for synchronous and metachronous PM were analysed with multivariate logistic and Cox proportional hazard regression models. RESULTS: Synchronous PM was most common in appendiceal cancer (23.5%), followed by colon (3.1%) and rectal (0.6%) cancer. The 5-year cumulative incidence was 9.0% for appendiceal, 2.5% for right colon, 1.8% for left colon and 1.2% for rectal cancer. In appendiceal cancer (n = 327), T4, N2, mucinous tumour, and non-radical surgery were associated with PM. In colon cancer (n = 24,399), synchronous PM were primarily associated with T4 (OR 18.37, 95% CI 8.12-41.53), T3 and N2 but also with N1, right-sided tumour, mucinous tumour, vascular and perineural invasion, female gender, age <60 and emergency surgery. These factors were also associated with metachronous PM. In rectal cancer (n = 10,394), T4 (OR 19.12, 95% CI 5.52-66.24), proximal tumour and mucinous tumour were associated with synchronous PM and T4 and mucinous tumour with metachronous PM. CONCLUSIONS: This study shows that appendiceal cancer, right-sided colon cancer, advanced tumour and node stages and mucinous histopathology are the main high-risk features for PM and should increase the awareness of current or future PM. PMID- 29576464 TI - Normalization and the Cholinergic Microcircuit: A Unified Basis for Attention. AB - Attention alters three key properties of population neural activity - firing rate, rate variability, and shared variability between neurons. All three properties are well explained by a single canonical computation - normalization - that acts across hierarchically integrated brain systems. Combining data from rodents and nonhuman primates, we argue that cortical cholinergic modulation originating from the basal forebrain closely mimics the effects of directed attention on these three properties of population neural activity. Cholinergic modulation of the cortical microcircuit underlying normalization may represent a key biological basis for the rapid and flexible changes in population neuronal coding that are required by directed attention.

AB - In London, November 1915, a telegram was received at the home of William Henry Bragg from the secretary of the Academy of Science in Stockholm announcing the award of the Nobel Prize in Physics for "the analysis of crystal structures by means of X-rays". A second similar telegram was addressed to his 25 year old son William Lawrence Bragg (Jenkin, 2008). This article commemorates the centenary of that event and the unveiling of a bust of Sir William Bragg alongside that of his son, Sir Lawrence Bragg, on North Terrace in Adelaide where he spent 23 years of his early career. PMID- 29576467 TI - Apelin and apelin receptor at different stages of corpus luteum development and effect of apelin on progesterone secretion and 3beta-hydroxysteroid dehydrogenase (3beta-HSD) in pigs. AB - Recent studies have suggested that apelin has a role in controlling female reproduction. The aims of the present study were, firstly, to investigate the gene expression (mRNA and protein) and immunolocalization of apelin and its receptor APJ in corpora lutea (CL) of pigs collected during the early (CL1), middle (CL2) and late (CL3) luteal phase. Using real time PCR and immunoblotting techniques, it was observed that apelin gene expression was similar in CL1 and CL2, and less in CL3, while relative abundance APJ mRNA and abundance of the protein were similar in CL1 and CL3 and greater in CL2. There was apelin staining in the cytoplasm of both small (SC) and large (LC) luteal cells with the greatest intensity in CL2. In the cytoplasm of CL1, only a few SC cells stained for APJ; in CL2, APJ was located in the cell membrane of LC and in the cytoplasm of SC; and in CL3 was located in the membrane with moderate cytoplasmic APJ staining. Intense APJ staining was noted in epithelium of blood vessels of CL2-3. Secondly, there was an effect of apelin on progesterone (P4) secretion in CL2 and on the molecular mechanisms of these cells. Stimulatory effects of apelin on P4 secretion, 3beta-hydroxysteroid dehydrogenase (HSD) activity and protein abundance were observed and this was inhibited in response to APJ and adenosine 5'-monophosphate-activated protein kinase (AMPKalpha) kinase blockers. In conclusion, the presence of apelin/APJ in the CL of pigs and stimulatory effects of apelin on P4 secretion and 3beta-HSD levels suggest potential auto/paracrine regulation by apelin in the luteal phase of the estrous cycle. Moreover, the involvement of APJ and AMPKalpha kinase in apelin activity in CL was confirmed. PMID- 29576468 TI - Retrieval and cryopreservation of sperm in spermatophores from cadaveric Indian white shrimp, Fenneropenaeus indicus (H. Milne Edwards, 1837). AB - This study focused on the quality of sperm obtained from spermatophores of cadaveric shrimp after long-term storage. Spermatophores were collected using the stripping method, which has resulted in maximum sperm viability when this approach was previously used. Cryoprotectants toxicity assessment of samples was conducted using dimethyl sulfoxide (DMSO), methanol (MeOH), ethylene glycol (EG), glycerol (Gly), dimethyl acetamide (DMA) and propylene glycol (PG) at different concentrations (5%, 10% and 30% v/v), prepared in Ca-F saline. Based on the results from the cryoprotectant toxicity assay, DMSO and MeOH were used individually as well as in combination for the subsequent study. Samples along with cryoprotectants were subjected to slow and fast freezing protocols (i.e. 0.5, and -10 degrees C/min to a final temperature of -80 degrees C) and were subsequently stored in LN2 (196 degrees C). Similarly, vitrification was performed by plunging the samples directly in to LN2. Samples of control and cryopreserved spermatophores that were stored for 45 days had sperm viabilities of 91.4 +/- 3.6% and 53.9 +/- 4.7%, respectively. Further observations with HOST and DNA integrity analyses of the cryopreserved sperm, resulted in percentages of 45.6 +/- 4.2%; 58.1 +/- 1.7% compared to control values of 82.3 +/- 4.8%; 94.3 +/ 1.9%, respectively. Use of the one-step slow freezing protocol at the rate of 0.5 degrees C/min between 4 degrees C and -80 degrees C in LN2 with DMSO (5%) + MeOH (5%) was a desirable preservation strategy of spermatophores, compared to other freezing protocols. Unlike sperm viability, the HOST results affirm the fertility potential of the sperm that have the capacity to participate in the fertilization process. Thus, the results of this study demonstrate that long term storage of sperm in spermatophores of Fenneropenaeus indicus collected from cadaveric specimens can result in viable sperm after cryopreservation if extender (Ca-F saline) containing DMSO and MeOH are used. PMID- 29576469 TI - Pathogenesis of endometriosis: Interaction between Endocrine and inflammatory pathways. AB - Despite an estimated prevalence of 11% in women and plausible historical descriptions dating back to the 17th century, the etiology of endometriosis remains poorly understood. Classical theories of the histological origins of endometriosis are reviewed below. Clinical presentations are variable, and signs and symptoms do not correlate well with the extent of disease. In this summary, we have attempted to synthesize the growing evidence that hormonal and immune factors conspire to activate a local inflammatory microenvironment that encourages endometriosis to persist and elaborate mediators of its two cardinal symptoms: pain and infertility. Surprisingly, in the search for novel therapeutics for medical treatment of endometriosis, some compounds appear to have dual pharmacological functions, simultaneously modifying the endocrine and immune system facets of this complex gynecologic syndrome. We predict that these lead drugs will provide more therapeutic choices for patients in the future. PMID- 29576470 TI - Building consensus and standards in fetal growth restriction studies. AB - Fetal growth restriction is a pathologic condition in which the fetus fails to reach its biologically based growth potential. There is inconsistency in terminology, definition, monitoring, and management, both in clinical practice and in the existing literature. This hampers interpretation and comparison of cohorts and studies. Standardization is essential. With the lack of a golden standard, or the opportunity to come to empirical evidence, consensus procedures can help to establish standardization. Consensus procedures provide no new information but formulate an agreement (as second best in the absence of robust evidence) for clinical and/or research practice on the basis of existing data. Consensus agreements need to be updated when new evidence becomes available and can change over time. In this chapter, we address the different issues that lack uniformity in FGR studies and management. Furthermore, we discuss several consensus methods and recent consensus procedures regarding fetal growth restriction. PMID- 29576471 TI - Extremely Divergent Haplotypes in Two Toxin Gene Complexes Encode Alternative Venom Types within Rattlesnake Species. AB - Natural selection is generally expected to favor one form of a given trait within a population. The presence of multiple functional variants of traits involved in activities such as feeding, reproduction, or the defense against predators is relatively uncommon within animal species. The genetic architecture and evolutionary mechanisms underlying the origin and maintenance of such polymorphisms are of special interest. Among rattlesnakes, several instances of the production of biochemically distinct neurotoxic or hemorrhagic venom types within the same species are known. Here, we investigated the genetic basis of this phenomenon in three species and found that neurotoxic and hemorrhagic individuals of the same species possess markedly different haplotypes at two toxin gene complexes. For example, neurotoxic and hemorrhagic Crotalus scutulatus individuals differ by 5 genes at the phospholipase A2 (PLA2) toxin gene complex and by 11 genes at the metalloproteinase (MP) gene complex. A similar set of extremely divergent haplotypes also underlies alternate venom types within C. helleri and C. horridus. We further show that the MP and PLA2 haplotypes of neurotoxic C. helleri appear to have been acquired through hybridization with C. scutulatus-a rare example of the horizontal transfer of a potentially highly adaptive suite of genes. These large structural variants appear analogous to immunity gene complexes in host-pathogen arms races and may reflect the impact of balancing selection at the PLA2 and MP complexes for predation on different prey. PMID- 29576472 TI - Metabolic Costs of Feeding Predictively Alter the Spatial Distribution of Individuals in Fish Schools. AB - Group living is ubiquitous among animals [1, 2], but the exact benefits of group living experienced by individual groupmates is related to their spatial location within the overall group [3-5]. Individual variation in behavioral traits and nutritional state is known to affect interactions between individuals and their social group [6, 7], but physiological mechanisms underpinning collective animal behavior remain largely unexplored [8]. Here, we show that while fish at the front of moving groups are most successful at capturing food items, these individuals then show a systematic, post-feeding movement toward the rear of groups. Using observations of fish feeding in groups coupled with estimates of metabolic rate in fish consuming different meal sizes, we demonstrate that the magnitude of this shift in spatial position is directly related to the aerobic metabolic scope remaining after accounting for energetic costs of digestion. While previous work has shown that hungry individuals occupy anterior positions in moving groups [9, 10], our results show that the metabolic demand of food processing reduces the aerobic capacity available for locomotion in individuals that eat most, thus preventing them from maintaining leading positions. This basic trade-off between feeding and locomotor capacity could fundamentally dictate the spatial position of individuals within groups, perhaps obviating the role of individual traits in determining spatial preferences over shorter timescales (e.g., hours to days). This may be a general constraint for individuals within animal collectives, representing a key, yet overlooked, mediator of group functioning that could affect leadership, social information transfer, and group decision making. PMID- 29576473 TI - Host-Polarized Cell Growth in Animal Symbionts. AB - To determine the fundamentals of cell growth, we must extend cell biological studies to non-model organisms. Here, we investigated the growth modes of the only two rods known to widen instead of elongating, Candidatus Thiosymbion oneisti and Thiosymbion hypermnestrae. These bacteria are attached by one pole to the surface of their respective nematode hosts. By incubating live Ca. T. oneisti and T. hypermnestrae with a peptidoglycan metabolic probe, we observed that the insertion of new cell wall starts at the poles and proceeds inward, concomitantly with FtsZ-based membrane constriction. Remarkably, in Ca. T. hypermnestrae, the proximal, animal-attached pole grows before the distal, free pole, indicating that the peptidoglycan synthesis machinery is host oriented. Immunostaining of the symbionts with an antibody against the actin homolog MreB revealed that it was arranged medially-that is, parallel to the cell long axis-throughout the symbiont life cycle. Given that depolymerization of MreB abolished newly synthesized peptidoglycan insertion and impaired divisome assembly, we conclude that MreB function is required for symbiont widening and division. In conclusion, our data invoke a reassessment of the localization and function of the bacterial actin homolog. PMID- 29576474 TI - The Tyrosine Phosphatase STEP Is Involved in Age-Related Memory Decline. AB - Cognitive disabilities that occur with age represent a growing and expensive health problem. Age-associated memory deficits are observed across many species, but the underlying molecular mechanisms remain to be fully identified. Here, we report elevations in the levels and activity of the striatal-enriched phosphatase (STEP) in the hippocampus of aged memory-impaired mice and rats, in aged rhesus monkeys, and in people diagnosed with amnestic mild cognitive impairment (aMCI). The accumulation of STEP with aging is related to dysfunction of the ubiquitin proteasome system that normally leads to the degradation of STEP. Higher level of active STEP is linked to enhanced dephosphorylation of its substrates GluN2B and ERK1/2, CREB inactivation, and a decrease in total levels of GluN2B and brain derived neurotrophic factor (BDNF). These molecular events are reversed in aged STEP knockout and heterozygous mice, which perform similarly to young control mice in the Morris water maze (MWM) and Y-maze tasks. In addition, administration of the STEP inhibitor TC-2153 to old rats significantly improved performance in a delayed alternation T-maze memory task. In contrast, viral-mediated STEP overexpression in the hippocampus is sufficient to induce memory impairment in the MWM and Y-maze tests, and these cognitive deficits are reversed by STEP inhibition. In old LOU/C/Jall rats, a model of healthy aging with preserved memory capacities, levels of STEP and GluN2B are stable, and phosphorylation of GluN2B and ERK1/2 is unaltered. Altogether, these data suggest that elevated levels of STEP that appear with advancing age in several species contribute to the cognitive declines associated with aging. PMID- 29576475 TI - Comprehensive Identification and Spatial Mapping of Habenular Neuronal Types Using Single-Cell RNA-Seq. AB - The identification of cell types and marker genes is critical for dissecting neural development and function, but the size and complexity of the brain has hindered the comprehensive discovery of cell types. We combined single-cell RNA seq (scRNA-seq) with anatomical brain registration to create a comprehensive map of the zebrafish habenula, a conserved forebrain hub involved in pain processing and learning. Single-cell transcriptomes of ~13,000 habenular cells with 4* cellular coverage identified 18 neuronal types and dozens of marker genes. Registration of marker genes onto a reference atlas created a resource for anatomical and functional studies and enabled the mapping of active neurons onto neuronal types following aversive stimuli. Strikingly, despite brain growth and functional maturation, cell types were retained between the larval and adult habenula. This study provides a gene expression atlas to dissect habenular development and function and offers a general framework for the comprehensive characterization of other brain regions. PMID- 29576476 TI - Unravelling the Molecular Determinants of Bee Sensitivity to Neonicotinoid Insecticides. AB - The impact of neonicotinoid insecticides on the health of bee pollinators is a topic of intensive research and considerable current debate [1]. As insecticides, certain neonicotinoids, i.e., N-nitroguanidine compounds such as imidacloprid and thiamethoxam, are as intrinsically toxic to bees as to the insect pests they target. However, this is not the case for all neonicotinoids, with honeybees orders of magnitude less sensitive to N-cyanoamidine compounds such as thiacloprid [2]. Although previous work has suggested that this is due to rapid metabolism of these compounds [2-5], the specific gene(s) or enzyme(s) involved remain unknown. Here, we show that the sensitivity of the two most economically important bee species to neonicotinoids is determined by cytochrome P450s of the CYP9Q subfamily. Radioligand binding and inhibitor assays showed that variation in honeybee sensitivity to N-nitroguanidine and N-cyanoamidine neonicotinoids does not reside in differences in their affinity for the receptor but rather in divergent metabolism by P450s. Functional expression of the entire CYP3 clade of P450s from honeybees identified a single P450, CYP9Q3, that metabolizes thiacloprid with high efficiency but has little activity against imidacloprid. We demonstrate that bumble bees also exhibit profound differences in their sensitivity to different neonicotinoids, and we identify CYP9Q4 as a functional ortholog of honeybee CYP9Q3 and a key metabolic determinant of neonicotinoid sensitivity in this species. Our results demonstrate that bee pollinators are equipped with biochemical defense systems that define their sensitivity to insecticides and this knowledge can be leveraged to safeguard bee health. PMID- 29576477 TI - Depletion of Maternal Cyclin B3 Contributes to Zygotic Genome Activation in the Ciona Embryo. AB - Most animal embryos display a delay in the activation of zygotic transcription during early embryogenesis [1]. This process is thought to help coordinate rapid increases in cell number during early development [2]. The timing of zygotic genome activation (ZGA) during the maternal-to-zygotic transition (MZT) remains uncertain despite extensive efforts. We explore ZGA in the simple protovertebrate, Ciona intestinalis. Single-cell RNA sequencing (RNA-seq) assays identified Cyclin B3 (Ccnb3) as a putative mediator of ZGA. Maternal Ccnb3 transcripts rapidly diminish in abundance during the onset of zygotic transcription at the 8-cell and 16-cell stages. Disruption of Ccnb3 activity results in precocious activation of zygotic transcription, while overexpression abolishes normal activation. These observations suggest that the depletion of maternal Cyclin B3 products is a critical component of the MZT and ZGA. We discuss evidence that this mechanism might play a conserved role in the MZT of other metazoans, including mice and humans. PMID- 29576479 TI - Mixed methods formative evaluation of a collaborative care program to decrease risky opioid prescribing and increase non-pharmacologic approaches to pain management. AB - INTRODUCTION: Opioid prescribing and subsequent rates of serious harms have dramatically increased in the past two decades, yet there are still significant barriers to reduction of risky opioid regimens. This formative evaluation utilized a mixed-methods approach to identify barriers and factors that may facilitate the successful implementation of Primary Care-Integrated Pain Support (PIPS), a clinical program designed to support the reduction of risky opioid regimens while increasing the uptake of non-pharmacologic treatment modalities. METHODS: Eighteen Department of Veterans Affairs (VA) employees across three sites completed a survey consisting of the Organizational Readiness for Implementing Change (ORIC) scale; a subset of these individuals (n = 9) then completed a semi-structured qualitative phone interview regarding implementing PIPS within the VA. ORIC results were analyzed using descriptive statistics while interview transcripts were coded and sorted according to qualitative themes. RESULTS: Quantitative analysis based on ORIC indicated high levels of organizational readiness to implement PIPS. Interview analysis revealed several salient themes: system-level barriers such as tension among various pain management providers; patient-level barriers such as perception of support and tension between patient and provider; and facilitating factors of PIPS, such as the importance of the clinical pharmacist role. CONCLUSIONS: While organizational readiness for implementing PIPS appears high, modifications to our implementation facilitation strategy (e.g., establishing clinical pharmacists as champions; marketing PIPS to leadership as a way to improve VA opioid safety metrics) may improve capacity of the sites to implement PIPS successfully. PMID- 29576478 TI - Mammalian Oocytes Locally Remodel Follicular Architecture to Provide the Foundation for Germline-Soma Communication. AB - Germ cells develop in a microenvironment created by the somatic cells of the gonad [1-3]. Although in males, the germ and somatic support cells lie in direct contact, in females, a thick extracellular coat surrounds the oocyte, physically separating it from the somatic follicle cells [4]. To bypass this barrier to communication, narrow cytoplasmic extensions of the follicle cells traverse the extracellular coat to reach the oocyte plasma membrane [5-9]. These delicate structures provide the sole platform for the contact-mediated communication between the oocyte and its follicular environment that is indispensable for production of a fertilizable egg [8, 10-15]. Identifying the mechanisms underlying their formation should uncover conserved regulators of fertility. We show here in mice that these structures, termed transzonal projections (TZPs), are specialized filopodia whose number amplifies enormously as oocytes grow, enabling increased germ-soma communication. By creating chimeric complexes of genetically tagged oocytes and follicle cells, we demonstrate that follicle cells elaborate new TZPs that push through the extracellular coat to reach the oocyte surface. We further show that growth-differentiation factor 9, produced by the oocyte, drives the formation of new TZPs, uncovering a key yet unanticipated role for the germ cell in building these essential bridges of communication. Moreover, TZP number and germline-soma communication are strikingly reduced in reproductively aged females. Thus, the growing oocyte locally remodels follicular architecture to ensure that its developmental needs are met, and an inability of somatic follicle cells to respond appropriately to oocyte-derived cues may contribute to human infertility. PMID- 29576480 TI - Nutritional Support from the Intestinal Microbiota Improves Hematopoietic Reconstitution after Bone Marrow Transplantation in Mice. AB - Bone marrow transplantation (BMT) offers curative potential for patients with high-risk hematologic malignancies, but the post-transplantation period is characterized by profound immunodeficiency. Recent studies indicate that the intestinal microbiota not only regulates mucosal immunity, but can also contribute to systemic immunity and hematopoiesis. Using antibiotic-mediated microbiota depletion in a syngeneic BMT mouse model, here we describe a role for the intestinal flora in hematopoietic recovery after BMT. Depletion of the intestinal microbiota resulted in impaired recovery of lymphocyte and neutrophil counts, while recovery of the hematopoietic stem and progenitor compartments and the erythroid lineage were largely unaffected. Depletion of the intestinal microbiota also reduced dietary energy uptake and visceral fat stores. Caloric supplementation through sucrose in the drinking water improved post-BMT hematopoietic recovery in mice with a depleted intestinal flora. Taken together, we show that the intestinal microbiota contribute to post-BMT hematopoietic reconstitution in mice through improved dietary energy uptake. PMID- 29576481 TI - The Monocot-Specific Receptor-like Kinase SDS2 Controls Cell Death and Immunity in Rice. AB - Programmed cell death (PCD) plays critical roles in plant immunity but must be regulated to prevent excessive damage. The E3 ubiquitin ligase SPL11 negatively regulates PCD and immunity in plants. We show that SPL11 cell-death suppressor 2 (SDS2), an S-domain receptor-like kinase, positively regulates PCD and immunity in rice by engaging and regulating SPL11 and related kinases controlling defense responses. An sds2 mutant shows reduced immune responses and enhanced susceptibility to the blast fungus Magnaporthe oryzae. Conversely, SDS2 over expression induces constitutive PCD accompanied by elevated immune responses and enhanced resistance to M. oryzae. SDS2 interacts with and phosphorylates SPL11, which in turn ubiquitinates SDS2, leading to its degradation. In addition, SDS2 interacts with related receptor-like cytoplasmic kinases, OsRLCK118/176, that positively regulate immunity by phosphorylating the NADPH oxidase OsRbohB to stimulate ROS production. Thus, a plasma membrane-resident protein complex consisting of SDS2, SPL11, and OsRLCK118/176 controls PCD and immunity in rice.

PMID- 29576482 TI - Lung Epithelial Cells Coordinate Innate Lymphocytes and Immunity against Pulmonary Fungal Infection. AB - Lung epithelial cells (LECs) are strategically positioned in the airway mucosa to provide barrier defense. LECs also express pattern recognition receptors and a myriad of immune genes, but their role in immunity is often concealed by the activities of "professional" immune cells, particularly in the context of fungal infection. Here, we demonstrate that NF-kappaB signaling in LECs is essential for immunity against the pulmonary fungal pathogen Blastomyces dermatitidis. LECs orchestrate innate antifungal immunity by augmenting the numbers of interleukin 17A (IL-17A)- and granulocyte-macrophage colony-stimulating factor (GM-CSF) producing innate lymphocytes, specifically "natural" Th17 (nTh17) cells. Innate lymphocyte-derived IL-17A and GM-CSF in turn enable phagocyte-driven fungal killing. LECs regulate the numbers of nTh17 cells via the production of chemokines such as CCL20, a process dependent on IL-1alpha-IL-1 receptor (IL-1R) signaling on LECs. Therefore, LECs orchestrate IL-17A- and GM-CSF-mediated immunity in an IL-1R-dependent manner and represent an essential component of innate immunity to pulmonary fungal pathogens.

PMID- 29576485 TI - Preoperative Glycemic Control Predicts Perioperative Serum Glucose Levels in Patients Undergoing Total Joint Arthroplasty. AB - BACKGROUND: Diabetic patients undergoing total joint arthroplasty (TJA) with postoperative hyperglycemia >200 mg/dL have increased the risk of prosthetic joint infection (PJI). We investigated the correlation between preoperative hemoglobin A1c (A1c) and postoperative hyperglycemia in diabetic patients undergoing TJA. METHODS: A retrospective review of 773 diabetic patients undergoing TJA was conducted. A Youden's J computational analysis determined the A1c where postoperative glucose levels >200 mg/dL were statistically more likely. Patients were then stratified into 3 groups: A1c <7%, A1c 7.0-8.0%, and A1c >8.0%. Outcomes included the highest postoperative in-hospital serum glucose level and PJI. RESULTS: We determined an A1c >7.45% resulted in a greater chance of postoperative hyperglycemia >200 mg/dL. Average postoperative serum glucose increased with A1c (A1c < 7 = 167 mg/dL, A1c 7.0-8.0 = 240 mg/dL, and A1c > 8 = 276 mg/dL, P < .0001). PJI did not statistically increase with A1c (2.25%, 1.99%, and 4.55%, respectively, P = .4319). CONCLUSION: Preoperative hemoglobin A1c levels correlate with postoperative glucose levels. We recommend using an A1c cutoff of 7.45% for patients undergoing TJA and suggest that caution should be exercised in patients with elevated A1c levels undergoing TJA. PMID- 29576486 TI - Characterization of Outcomes of 2-Stage Exchange Arthroplasty in the Treatment of Prosthetic Joint Infections. AB - BACKGROUND: Two-stage revision is the preferred treatment for prosthetic hip and knee infections in the United States. Recent studies have questioned the true success rate of this treatment. The purpose of this study is to investigate outcomes of prosthetic hip and knee infections undergoing resection arthroplasty and spacer insertion at a single institution. METHODS: We identified 103 patients who underwent prosthesis resection and spacer placement for infection over a 10 year period. Twenty-three cases were excluded based on preset exclusion criteria leaving 80 cases (56 knees, 24 hips). A retrospective review was performed to examine the outcomes of these patients. RESULTS: Following spacer placement but before reimplantation, 9 (11.25%) of the 80 joints underwent repeat debridement and spacer exchange for persistent infection. Twenty-four (30.00%) patients had a serious complication during their treatment course. Fourteen (17.50%) patients never underwent reimplantation. Of these, 10 continued with spacer retention, 2 had resection arthroplasty, and 1 each had an amputation and an arthrodesis. Of the 66 patients with successful reimplantation, 48 (72.70%) remained infection free at most recent follow-up. CONCLUSIONS: Two-stage revision does not result in the high rates of cure reported previously, when taking into account the substantial number of patients who never undergo the subsequent reimplantation surgery. Of those who underwent reimplantation in our study, many required additional spacer exchange or had complications. Surgeons and patients should consider these outcomes when discussing the treatment of prosthetic hip and knee infections. PMID- 29576487 TI - Total Knee Arthroplasty With Patellar Retention: The Severity of Patellofemoral Osteoarthritis Did Not Affect the Clinical and Radiographic Outcomes. AB - BACKGROUND: The purpose of this study is to compare the clinical and radiographic outcomes of total knee arthroplasty (TKA) with patellar retention in accordance with the severity of patellofemoral arthritis. METHODS: We retrospectively reviewed patients who underwent TKA with patellar retention using the NexGen LPS or LPS-flex system between September 2010 and May 2015. The radiographic severity of patellofemoral arthritis was categorized according to the Iwano classification system, and subjects were divided into mild (stage 0-I) and moderate to severe (stage II-IV) groups. Clinical outcomes were evaluated using the Hospital for Special Surgery score, Knee Society Score, function score, Western Ontario and McMaster Universities Osteoarthritis Index, and Feller score. Radiographic outcomes were assessed using the congruence angle, patellar tilt angle, and lateral patellar displacement. The minimum follow-up for clinical and radiographic evaluation was 2 years. Clinical and radiographic outcomes were compared between the 2 groups preoperatively and at the time of the last follow up. RESULTS: Four hundred seventy-four knees were enrolled and assigned to mild (n = 208) or moderate to severe (n = 266) groups. The preoperative Feller score was significantly lower in the moderate to severe group (P = .030), whereas the postoperative clinical and radiographic results did not differ significantly between the 2 groups. CONCLUSION: Clinical and radiographic outcomes did not differ in accordance with the severity of patellofemoral arthritis after a minimum 2 years of follow-up of patients treated with TKA with patellar retention. Good outcomes were obtained with patellar retention in TKA, even in patients with advanced patellofemoral osteoarthritis. PMID- 29576488 TI - Can a Single-Use and Patient-Specific Instrumentation Be Reliably Used in Primary Total Knee Arthroplasty? A Multicenter Controlled Study. AB - BACKGROUND: The aim of this controlled multicenter study is to evaluate the clinical and radiologic outcomes of primary total knee arthroplasty (TKA) using single-use fully disposable and patient-specific cutting guides (SU) and compare the results to those obtained with traditional patient-specific cutting guides (PSI) vs conventional instrumentation (CI). METHODS: Seventy consecutive patients had their TKA performed using SU. They were compared to 140 historical patients requiring TKA that were randomized to have the procedure performed using PSI vs CI. The primary measure outcome was mechanical axis as measured on a standing long-leg radiograph using the hip-knee-ankle angle. Secondary outcome measures were Knee Society and Oxford knee scores, operative time, need for postoperative transfusion, and length of hospital stay. RESULTS: The mean hip-knee-ankle value was 179.8 degrees (standard deviation [SD] 3.1 degrees ), 179.2 degrees (SD 2.9 degrees ), and 178.3 degrees (SD 2.5 degrees ) in the CI, PSI and SU groups, respectively (P = .0082). Outliers were identified in 16 of 65 (24.6%), 15 of 67 (22.4%), and 14 of 70 (20.0%) knees in the CI, PSI, and SU group, respectively (P = .81). There was no significant difference in the clinical results (P = .29 and .19, respectively). Operative time, number of unit transfusion, and length of hospital stay were not significantly different between the 3 groups (P = .45, .31, and 0.98, respectively). CONCLUSION: The use of an SU in TKA provided similar clinical and radiologic results to those obtained with traditional PSI and CI. The potential economic advantages of single-use instrumentation in primary TKA require further investigation. PMID- 29576489 TI - Outcomes of Primary Total Knee Arthroplasty in Patients With Parkinson's Disease. AB - BACKGROUND: Parkinson's disease is a degenerative disorder causing rigidity, bradykinesia, and tremor of the motor system. There is significant paucity of evidence regarding whether total knee arthroplasty (TKA) is of benefit in patients with both Parkinson's disease and osteoarthritis. We aimed to compare outcomes and complications of TKA between patients with Parkinson's disease and those without. METHODS: A cohort of 43 knees from 35 patients with Parkinson's disease who received a primary TKA between January 2004 and December 2015 were retrospectively extracted from a private clinical database held by 2 surgeons and compared to an age and gender-matched control group of 50 knees from 41 patients. TKAs were performed by 2 surgeons at 1 tertiary private hospital.The indication for TKA in both groups was osteoarthritis. Difference between preoperative and 1 year range of movement (ROM) and 12-point Oxford Knee Score (OKS) was assessed using Student's unpaired t-test. Postoperative complications and revision procedures were also recorded during the follow-up period. The minimal clinically important difference for OKS at 1-year follow-up, defined as improvement of >=6, was also assessed. RESULTS: In the Parkinson's group, mean ROM improvement was 14 degrees (100 degrees preoperatively to 114 degrees at 12 months), compared to 12 degrees in the control group (102 degrees -114 degrees , respectively). Mean OKS improvement was 15 in the Parkinson's group (23 preoperatively to 38 at 12 months) compared to 17 in the control group (23 and 40, respectively.) No significant difference was identified between the 2 groups for either ROM (P = .96) or OKS (P = .45.) All Parkinson's patients achieved the minimal clinically important difference at 1-year follow-up. There were no mortalities during the study follow-up period and no significant difference in complication rates between the 2 groups (P = .41). CONCLUSION: Parkinson's disease was not associated with poorer functional outcomes or increased complications compared to controls in our study. We suggest that Parkinson's disease is not an absolute contraindication to TKA. PMID- 29576490 TI - Is the inclinometer a valid measure of thoracic kyphosis? A cross-sectional study. AB - BACKGROUND: Radiographs are used to monitor thoracic kyphosis in individuals with certain pathologies (e.g. osteoporosis), exposing patients to potentially harmful radiation. Thus, other measures for monitoring the progression of thoracic kyphosis are desirable. The gravity-dependent inclinometer has been shown to be reliable but its validity as a measure of thoracic kyphosis has not been investigated. OBJECTIVES: To determine the validity of the gravity-dependent (analogue) inclinometer for measuring thoracic kyphosis. DESIGN: Cross-sectional study. METHOD: Participants (n=78) were recruited as part of a larger study of shoulder impingement syndrome. Healthy participants (n=39) were age and gender matched to the shoulder impingement syndrome group (n=39). Measurements of thoracic kyphosis using a gravity-dependent inclinometer were compared with modified Cobb angle results obtained from a sagittal view of lateral radiographs. A Bland-Altman plot assessed agreement. The Pearson correlation coefficient and linear regression was used to determine the association between modified Cobb angles and inclinometer measurements. RESULTS: The Bland-Altman plot demonstrated good agreement. The Pearson correlation coefficient, r=0.62 (p<0.001), and linear regression model established a strong association between the thoracic kyphosis angle from the inclinometer readings and the modified Cobb angle measured from the radiographs (beta=0.47, 95% CI 0.29, 0.65, p<0.001, R2=0.52, n=78). Age as a confounder was included in the model (beta=0.35, 95% CI 0.19, 0.51, p<0.001). CONCLUSIONS: The gravity-dependent (analogue) inclinometer produces angles that are comparable to the modified Cobb angle obtained from radiographs, establishing its criterion validity as a safe clinical tool for measuring thoracic kyphosis.

PMID- 29576492 TI - Hippocampal sparing in stereotactic radiotherapy for brain metastases: To contour or not contour the hippocampus? AB - PURPOSE: The aim of our study was to evaluate hippocampal irradiation in patients treated with fractionated stereotactic brain radiotherapy. PATIENTS AND METHODS: Retrospective hippocampal dosimetric analysis performed on 22 patients with one to four brain metastases treated with fractionated stereotactic radiotherapy using volumetric intensity-modulated arc therapy. Original plans did not include hippocampus as avoidance structure in optimization criteria; hippocampus was retrospectively delineated on magnetic resonance coregistered with planning CT and using as reference the RTOG 0933 atlas. Hippocampus was defined both as a single and as pair organ. Constraints analysed were: Dmax<16Gy, D40%<7.3Gy, D100%=Dmin<9Gy. Assuming a alpha/beta ratio of 2Gy, biologically equivalent dose in 2Gy fractions was calculated. Hippocampal-sparing plans were developed in cases where hippocampal constraints were not respected in the original plan. RESULTS: Among constraints analysed Dmax and D40% have been exceeded in ten out of 22 cases. The constraints were not respected in patients with more than one metastatic lesion and in three patients with only one lesion. Considering all exceeded constraints values in non-hippocampal sparing plans, the 50% of them was respected after replanning. No significant differences were found among conformity and homogeneity index between non-hippocampal sparing and hippocampal sparing plans. CONCLUSION: Volumetric intensity-modulated arc therapy hippocampal sparing plans significantly decreases dose to hippocampus assuring an equal target coverage and organs at risk avoiding. PMID- 29576493 TI - Aspiration Thrombectomy versus Conventional Catheter-Directed Thrombolysis as First-Line Treatment for Noniatrogenic Acute Lower Limb Ischemia. AB - PURPOSE: To examine the efficacy, safety, and procedural costs of percutaneous aspiration thrombectomy (PAT) as a first-line treatment for noniatrogenic acute lower limb ischemia (ALI) compared with conventional catheter-directed thrombolysis (CDT). MATERIALS AND METHODS: All patients who underwent endovascular intervention for ALI from January 2015 to August 2017 were included. Fifteen patients were treated with the use of primary PAT and 27 patients were treated with the use of primary CDT. The primary end point was complete thrombus clearance with improvement in Thrombolysis in Myocardial Infarction (TIMI) score. Adjunctive treatment for thrombus removal was considered to indicate technical failure. Treatment of underlying chronic disease was not considered to indicate technical failure. Procedural costs for each patient were calculated by itemizing all disposable equipment, facility overheads, and staff costs. RESULTS: Of the 15 primary PAT patients, technical success was achieved in 8 (53%); the remaining 7 (47%) required adjunctive CDT. Of the 27 primary CDT patients, technical success was achieved in 25 (89%); the remaining 2 (11%) required adjunctive PAT. There were 4 complications in the primary PAT group: 2 were procedure related and of a minor grade. There were 8 complications in the primary CDT group: All were procedure-related, including 2 major groin/retroperitoneal hemorrhage and 1 death from intracranial hemorrhage. Limb salvage was attained in all patients. There were no significant differences in average procedural costs per patient between the 2 groups. CONCLUSIONS: First-line use of PAT for endovascular treatment of ALI can reduce the need for CDT, with no significant cost difference. PMID- 29576494 TI - Combined Fluoroscopy and Ultrasound-Guided Transjugular Kidney Biopsy in Cirrhotic Patients. AB - PURPOSE: To evaluate the safety and diagnostic yield of combined fluoroscopy and ultrasound-guided transjugular kidney biopsy (TJKB) in cirrhotic patients with suspected renal parenchymal disease. MATERIALS AND METHODS: A retrospective review was made of 27 patients (21 men; overall mean age 44.7 y) who underwent TJKB from June 2013 to June 2016; 21 patients had coagulopathy and/or thrombocytopenia, 4 underwent simultaneous TJKB with transjugular liver biopsy, and 1 patient each had severe obesity and gross ascites. All procedures were performed with the use of fluoroscopy and simultaneous transabdominal ultrasound guidance. The data were analyzed for number of passes taken, number of glomeruli in the tissue cores, adequacy of tissue core for histopathologic diagnosis, and incidence and severity of complications. RESULTS: The average number of passes per case was 3.6 (range 2-6). The total length of tissue cores ranged from 0.4 cm to 2.5 cm. The mean numbers of glomeruli per procedure on light microscopy were 6.7 (range 0-17). Diagnostic biopsy specimens were obtained in 23 out of 27 patients (85%). Eleven patients had minor complications. One patient had major complication in the form of hemoglobin drop of 2.1 mg/dL which required embolization and blood transfusion. CONCLUSIONS: Combined use of fluoroscopy and ultrasound guidance for TJKB yielded adequate tissue samples with fewer passes and a low rate of complications in high-risk patients with cirrhosis. PMID- 29576495 TI - The real-world effectiveness of vedolizumab on intestinal and articular outcomes in inflammatory bowel diseases. AB - BACKGROUND: The effectiveness of vedolizumab in real-world practice is under evaluation, while its role in inflammatory bowel disease-associated spondyloarthritis is still unclear. AIMS: To report real-world data about the effectiveness of vedolizumab on intestinal and articular symptoms after 10 and 22 weeks of treatment. METHODS: Web-based data from the cohort of the Sicilian Network for Inflammatory Bowel Disease (SN-IBD) were extracted to perform a prospective multicentre observational study. RESULTS: 163 patients (84 with Crohn's disease and 79 with ulcerative colitis) were included. At week 10, a steroid-free remission was achieved in 71 patients (43.6%), while at week 22 a steroid-free remission was obtained in 40.8% of patients. A response on articular symptoms was reported after 10 weeks of treatment in 17 out of 43 (39.5%) patients with active spondyloarthritis at baseline, and in 10 out of 22 (45.4%) patients at week 22. The only factor associated with articular response was the coexistence of clinical benefit on intestinal symptoms (at week 10: OR 8.471, p = 0.05; at week 22: OR 5.600, p = 0.08). CONCLUSIONS: Vedolizumab showed good effectiveness after 10 and 22 weeks of treatment. A subset of patients reported improvement also on articular symptoms, probably as a consequence of the concomitant control of gut inflammation.

PMID- 29576497 TI - Urine Proteome Profiling Predicts Lung Cancer from Control Cases and Other Tumors. AB - Development of noninvasive, reliable biomarkers for lung cancer diagnosis has many clinical benefits knowing that most of lung cancer patients are diagnosed at the late stage. For this purpose, we conducted proteomic analyses of 231 human urine samples in healthy individuals (n=33), benign pulmonary diseases (n=40), lung cancer (n=33), bladder cancer (n=17), cervical cancer (n=25), colorectal cancer (n=22), esophageal cancer (n=14), and gastric cancer (n=47) patients collected from multiple medical centers. By random forest modeling, we nominated a list of urine proteins that could separate lung cancers from other cases. With a feature selection algorithm, we selected a panel of five urinary biomarkers (FTL: Ferritin light chain; MAPK1IP1L: Mitogen-Activated Protein Kinase 1 Interacting Protein 1 Like; FGB: Fibrinogen Beta Chain; RAB33B: RAB33B, Member RAS Oncogene Family; RAB15: RAB15, Member RAS Oncogene Family) and established a combinatorial model that can correctly classify the majority of lung cancer cases both in the training set (n=46) and the test sets (n=14-47 per set) with an AUC ranging from 0.8747 to 0.9853. A combination of five urinary biomarkers not only discriminates lung cancer patients from control groups but also differentiates lung cancer from other common tumors. The biomarker panel and the predictive model, when validated by more samples in a multi-center setting, may be used as an auxiliary diagnostic tool along with imaging technology for lung cancer detection. PMID- 29576499 TI - A response to comments by Dr. Mohammad Alwardat on "Safety of repeated sessions of transcranial direct current stimulation: A systematic review". PMID- 29576498 TI - Evidence of transcranial direct current stimulation-generated electric fields at subthalamic level in human brain in vivo. AB - BACKGROUND: Transcranial direct current stimulation (tDCS) is a promising brain modulation technique for several disease conditions. With this technique, some portion of the current penetrates through the scalp to the cortex and modulates cortical excitability, but a recent human cadaver study questions the amount. This insufficient intracerebral penetration of currents may partially explain the inconsistent and mixed results in tDCS studies to date. Experimental validation of a transcranial alternating current stimulation-generated electric field (EF) in vivo has been performed on the cortical (using electrocorticography, ECoG, electrodes), subcortical (using stereo electroencephalography, SEEG, electrodes) and deeper thalamic/subthalamic levels (using DBS electrodes). However, tDCS generated EF measurements have never been attempted. OBJECTIVE: We aimed to demonstrate that tDCS generates biologically relevant EF as deep as the subthalamic level in vivo. METHODS: Patients with movement disorders who have implanted deep brain stimulation (DBS) electrodes serve as a natural experimental model for thalamic/subthalamic recordings of tDCS-generated EF. We measured voltage changes from DBS electrodes and body resistance from tDCS electrodes in three subjects while applying direct current to the scalp at 2 mA and 4 mA over two tDCS montages. RESULTS: Voltage changes at the level of deep nuclei changed proportionally with the level of applied current and varied with different tDCS montages. CONCLUSIONS: Our findings suggest that scalp-applied tDCS generates biologically relevant EF. Incorporation of these experimental results may improve finite element analysis (FEA)-based models. PMID- 29576500 TI - Dualistic effect of pallidal deep brain stimulation on motor speech disorders in dystonia. AB - BACKGROUND: Although pallidal deep brain stimulation (GPi-DBS) is an effective treatment for dystonia, it may cause important stimulation-induced side-effects such as hypokinetic dysarthria or stuttering. However, the reasons behind the occurrence of these side-effects remain unknown. OBJECTIVE: To objectively investigate the impact of GPi-DBS on patients with dystonia on speech fluency, intelligibility, and key aspects of hyperkinetic and hypokinetic dysarthria. METHODS: Speech was systematically evaluated in 19 dystonic patients with GPi DBS. Each patient was tested twice within one day in both the GPi-DBS ON and GPi DBS OFF stimulation conditions. A control sample of 19 matched healthy speakers underwent the same speech assessment. RESULTS: We observed an improvement of hyperkinetic dysarthria symptoms in 47% and an aggravation of hypokinetic dysarthria symptoms in 26% of patients with the GPi-DBS switched ON. A higher stimulus intensity was found in a group of patients in whom the hypokinetic dysarthria worsened with the GPi-DBS ON when compared to other dystonic patients (p = 0.02). Furthermore, we revealed a significant increase of dysfluent words in the GPi-DBS ON when compared to OFF condition (p = 0.001) associated with the shorter distance of the active contact localization along the medio-lateral direction (r = -0.70, p = 0.005). CONCLUSION: This study provides evidence of dualistic effects of GPi-DBS on speech in dystonia manifested as an improvement of hyperkinetic or a deterioration of hypokinetic dysarthria. Our findings suggest that lower stimulation parameters and placement of active contacts more laterally in the internal globus pallidus should be preferred to avoid the possible side effects of hypokinetic dysarthria and dysfluency. PMID- 29576501 TI - Intrastriatal transplantation of stem cells from human exfoliated deciduous teeth reduces motor defects in Parkinsonian rats. AB - BACKGROUND: This study explored the neural differentiation and therapeutic effects of stem cells from human exfoliated deciduous teeth (SHED) in a rat model of Parkinson's disease (PD). METHODS: The SHED were isolated from fresh dental pulp and were induced to differentiate to neurons and dopamine neurons by inhibiting similar mothers against dpp (SMAD) signaling with Noggin and increase conversion of dopamine neurons from SHED with CHIR99021, Sonic Hedgehog (SHH) and FGF8 in vitro. The neural-primed SHED were transplanted to the striatum of 6 hydroxydopamine (6-OHDA)-induced PD rats to evaluate their neural differentiation and functions in vivo. RESULTS: These SHED were efficiently differentiated to neurons (62.7%) and dopamine neurons (42.3%) through a newly developed method. After transplantation, the neural-induced SHED significantly improved recovery of the motor deficits of the PD rats. The grafted SHED were differentiated into neurons (61%), including dopamine neurons (22.3%), and integrated into the host rat brain by forming synaptic connections. Patch clamp analysis showed that neurons derived from grafted SHED have the same membrane potential profile as dopamine neurons, indicating these cells are dopamine neuron-like cells. The potential molecular mechanism of SHED transplantation in alleviating motor deficits of the rats is likely to be mediated by neuronal replacement and immune modulation as we detected the transplanted dopamine neurons and released immune cytokines from SHED. CONCLUSION: Using neural-primed SHED to treat PD showed significant restorations of motor deficits in 6-OHDA-induced rats. These observations provide further evidence that SHED can be used for cell-based therapy of PD. PMID- 29576502 TI - The healthy donor profile of immunoregulatory soluble mediators is altered by stem cell mobilization and apheresis. AB - BACKGROUND: Peripheral blood stem cells from healthy donors mobilized by granulocyte colony-stimulating factor (G-CSF) and thereafter harvested by leukapheresis are commonly used for allogeneic stem cell transplantation. METHODS: Plasma levels of 38 soluble mediators (cytokines, soluble adhesion molecules, proteases, protease inhibitors) were analyzed in samples derived from healthy stem cell donors before G-CSF treatment and after 4 days, both immediately before and after leukapheresis. RESULTS: Donors could be classified into two main subsets based on their plasma mediator profile before G-CSF treatment. Seventeen of 36 detectable mediators were significantly altered by G CSF; generally an increase in mediator levels was seen, including pro inflammatory cytokines, soluble adhesion molecules and proteases. Several leukocyte- and platelet-released mediators were increased during apheresis. Both plasma and graft mediator profiles were thus altered and showed correlations to graft concentrations of leukocytes and platelets; these concentrations were influenced by the apheresis device used. Finally, the mediator profile of the allotransplant recipients was altered by graft infusion, and based on their day +1 post-transplantation plasma profile our recipients could be divided into two major subsets that differed in overall survival. DISCUSSION: G-CSF alters the short-term plasma mediator profile of healthy stem cell donors. These effects together with the leukocyte and platelet levels in the graft determine the mediator profile of the stem cell grafts. Graft infusion also alters the systemic mediator profile of the recipients, but further studies are required to clarify whether such graft-induced alterations have a prognostic impact. PMID- 29576503 TI - Effective treatment of progressive MS remains elusive. PMID- 29576504 TI - Multiple sclerosis. AB - Multiple sclerosis continues to be a challenging and disabling condition but there is now greater understanding of the underlying genetic and environmental factors that drive the condition, including low vitamin D levels, cigarette smoking, and obesity. Early and accurate diagnosis is crucial and is supported by diagnostic criteria, incorporating imaging and spinal fluid abnormalities for those presenting with a clinically isolated syndrome. Importantly, there is an extensive therapeutic armamentarium, both oral and by infusion, for those with the relapsing remitting form of the disease. Careful consideration is required when choosing the correct treatment, balancing the side-effect profile with efficacy and escalating as clinically appropriate. This move towards more personalised medicine is supported by a clinical guideline published in 2018. Finally, a comprehensive management programme is strongly recommended for all patients with multiple sclerosis, enhancing health-related quality of life through advocating wellness, addressing aggravating factors, and managing comorbidities. The greatest remaining challenge for multiple sclerosis is the development of treatments incorporating neuroprotection and remyelination to treat and ultimately prevent the disabling, progressive forms of the condition. PMID- 29576506 TI - Overexpressing dominant-negative FGFR2-IIIb impedes lung branching morphogenesis in pigs. AB - Genetic studies with mouse models have shown that fibroblast growth factor receptor 2-IIIb (FGFR2-IIIb) plays crucial roles in lung development and differentiation. To evaluate the effect of FGFR2-IIIb in pig lung development, we employed somatic cell nuclear transfer (SCNT) technology to generate transgenic pig fetuses overexpressing the transmembrane (dnFGFR2-IIIb-Tm) and soluble (dnFGFR2-IIIb-HFc) forms of the dominant-negative human FGFR2-IIIb driven by the human surfactant protein C (SP-C) promoter, which was specifically expressed in lung epithelia. Eight dnFGFR2-IIIb-Tm transgenic and twelve dnFGFR2-IIIb-HFc transgenic pig fetuses were collected from three and two recipient sows, respectively. Repression of FGFR2-IIIb in lung epithelia resulted in smaller lobes and retardation of alveolarization in both forms of dnFGFR2-IIIb transgenic fetuses. Moreover, the dnFGFR2-IIIb-HFc transgenic ones showed more deterioration in lung development. Our results demonstrate that disruption of FGFR2-IIIb signaling in the epithelium impedes normal branching and alveolarization in pig lungs, which is less severe than the results observed in transgenic mice. The dnFGFR2-IIIb transgenic pig is a good model for the studies of blastocyst complementation as well as the mechanisms of lung development and organogenesis. PMID- 29576507 TI - A novel lncRNA, Lnc-OC1, promotes ovarian cancer cell proliferation and migration by sponging miR-34a and miR-34c. AB - Long non-coding RNAs (lncRNAs) have been reported to be of great importance in tumorigenesis and progression of a variety of cancers. However, the role of lncRNAs in ovarian cancer (OC) remains largely unknown. In the present study, we identified a novel lncRNA, LOC100288181 (named as Lnc-OC1), which acted as a key regulator in the development and progression of OC. The combined Gene Expression Omnibus (GEO) database analysis revealed that Lnc-OC1 was significantly upregulated in OC tissues and Kaplan-Meier survival analysis confirmed that high Lnc-OC1 expression was associated with poor prognosis of OC patients. Importantly, we also demonstrated that knockdown of Lnc-OC1 suppressed cell proliferation, colony formation, invasion and migration in vitro and inhibited tumorigenicity in vivo. Mechanistically, Lnc-OC1 repressed the expression of endogenous miR-34a and miR-34c as a sponge and vice versa. Moreover, rescue experiments demonstrated that the oncogenic function of Lnc-OC1 at least partially depended on suppressing miR-34a and miR-34c. In conclusion, our results suggest that the Lnc-OC1-miR-34a/34c axis may play a pivotal role in OC, and may serve as a potential diagnostic biomarker and a powerful therapeutic target for OC. PMID- 29576508 TI - The desumoylating enzyme sentrin-specific protease 3 contributes to myocardial ischemia reperfusion injury. AB - Sentrin-specific protease 3 (SENP3), a member of the desumoylating enzyme family, is known as a redox sensor and could regulate multiple cellular signaling pathways. However, its implication in myocardial ischemia reperfusion (MIR) injury is unclear. Here, we observed that SENP3 was expressed and upregulated in the mouse heart depending on reactive oxygen species (ROS) production in response to MIR injury. By utilizing siRNA-mediated cardiac specific gene silencing, SENP3 knockdown was demonstrated to significantly reduce MIR-induced infarct size and improve cardiac function. Mechanistic studies indicated that SENP3 silencing ameliorated myocardial apoptosis mainly via suppression of endoplasmic reticulum (ER) stress and mitochondrial-mediated apoptosis pathways. By contrast, adenovirus-mediated cardiac SENP3 overexpression significantly exaggerated MIR injury. Further molecular analysis revealed that SENP3 promoted mitochondrial translocation of dynamin-related protein 1 (Drp1) in reperfused myocardium. In addition, mitochondrial division inhibitor-1 (Mdivi-1), a pharmacological inhibitor of Drp1, significantly attenuated the exaggerated mitochondrial abnormality and cardiac injury by SENP3 overexpression after MIR injury. Taken together, we provide the first direct evidence that SENP3 upregulation pivotally contributes to MIR injury in a Drp1-dependent manner, and suggest that SENP3 suppression may hold therapeutic promise for constraining MIR injury. PMID- 29576509 TI - Synthesis of new 4-aryloxy-N-arylanilines and their inhibitory activities against succinate-cytochrome c reductase. AB - Succinate-cytochrome c reductase (SCR) is composed of a mixture of mitochondrial complex II (succinate-ubiquinone oxidoreductase) and complex III (cytochrome bc1 complex). Meanwhile, complexes II and III are two promising targets of numerous antibiotics and fungicides. With an aim to identify new lead structures for SCR, complex II or III, a new series of 4-aryloxy-N-arylanilines were synthesized by introducing a 4-aryloxy phenyl group as one of the aryl groups in diaryl amines. With the economic Cu(OAc)2.H2O as the optimal copper promoter, a simple and facile protocol was utilized to afford 24 target products in 56-93% yields. Furthermore, extensive screening results suggested variable inhibitory activities of these compounds against SCR. Exceptionally, compounds 7k-7n showed excellent inhibition potency with their IC50 values in the nanomolar range, demonstrating higher potency than the commercial controls (penthiopyrad and azoxystrobin) by over one order of magnitude. PMID- 29576510 TI - Probing cytochrome P450 bioactivation and fluorescent properties with morpholinyl tethered anthraquinones. AB - Structural features from the anticancer prodrug nemorubicin (MMDX) and the DNA binding molecule DRAQ5TM were used to prepare anthraquinone-based compounds, which were assessed for their potential to interrogate cytochrome P450 (CYP) functional activity and localisation. 1,4-disubstituted anthraquinone 8 was shown to be 5-fold more potent in EJ138 bladder cancer cells after CYP1A2 bioactivation. In contrast, 1,5-bis((2-morpholinoethyl)amino) substituted anthraquinone 10 was not CYP-bioactivated but was shown to be fluorescent and subsequently photo-activated by a light pulse (at a bandwidth 532-587 nm), resulting in punctuated foci accumulation in the cytoplasm. It also showed low toxicity in human osteosarcoma cells. These combined properties provide an interesting prospective approach for opto-tagging single or a sub-population of cells and seeking their location without the need for continuous monitoring. PMID- 29576511 TI - Thermal decomposition mechanisms of poly(vinyl chloride): A computational study. AB - The studies on the pyrolysis mechanisms of waste PVC contribute to development and application of pyrolysis technology for mixed waste plastics. In the article, the thermal decomposition mechanisms of model compound of poly(vinyl chloride) (PVC) have been investigated by employing density functional theory methods at M06-2X/6-31++G(d,p) level in order to illuminate the elimination of HCl and the formation of hydrocarbons. Various possible pyrolysis paths for the formation of main products were proposed, and the thermodynamic and kinetic parameters in every path were calculated. The calculation results show that the HCl elimination can occur through the concerted reaction and the energy barrier of HCl elimination changes from 167.4 to 243.3 kJ/mol; allyl group can obviously reduce the activation energy of HCl elimination, and the branched-chain can lower the energy barrier of HCl elimination at the carbon sites near the branch chain; a free radical is more easily converted into aromatic compound through a series of isomerizations, cyclization and dehydrogenation; the conjugated polyene could be decomposed in parallel reaction channels: one is the evolution of aromatics, another is the formation of small molecule products. The above analysis is consistent with previous experimental results and analysis. PMID- 29576512 TI - What gets measured gets managed: A new method of measuring household food waste. AB - The quantification of household food waste is an essential part of setting policies and waste reduction goals, but it is very difficult to estimate. Current methods include either direct measurements (physical waste surveys) or measurements based on self-reports (diaries, interviews, and questionnaires). The main limitation of the first method is that it cannot always trace the waste source, i.e., an individual household, whereas the second method lacks objectivity. This article presents a new measurement method that offers a solution to these challenges by measuring daily produced food waste at the household level. This method is based on four main principles: (1) capturing waste as it enters the stream, (2) collecting waste samples at the doorstep, (3) using the individual household as the sampling unit, and (4) collecting and sorting waste daily. We tested the feasibility of the new method with an empirical study of 192 households, measuring the actual amounts of food waste from households as well as its composition. Household food waste accounted for 45% of total waste (573 g/day per capita), of which 54% was identified as avoidable. Approximately two thirds of avoidable waste consisted of vegetables and fruit. These results are similar to previous findings from waste surveys, yet the new method showed a higher level of accuracy. The feasibility test suggests that the proposed method provides a practical tool for policy makers for setting policy based on reliable empirical data and monitoring the effectiveness of different policies over time. PMID- 29576513 TI - Areas on which to focus when seeking to reduce the greenhouse gas emissions of commercial waste management. A case study of a hypermarket, Finland. AB - This study focuses on commercial waste, which has received less attention than household waste in regards to greenhouse gas emission research. First, the global warming potential (GWP) of commercial waste management was calculated. Second, the impacts of different waste fractions and the processes of waste management were recognised. Third, the key areas on which to focus when aiming to reduce the greenhouse gas emissions of commercial waste management were determined. This study was conducted on the waste generated by a real hypermarket in South-East Finland and included eight different waste fractions. The waste treatment plants were selected based on the actual situation. Three different scenarios were employed to evaluate the environmental impact of managing mixed waste: landfilling, combustion and more accurate source separation. The GaBi software and impact assessment methodology CML 2001 were used to perform a life cycle assessment of the environmental impacts associated with the waste management. The results indicated that the total GWP of commercial waste management could be reduced by 93% by directing the mixed waste to combustion instead of landfill. A further 5% GWP reduction could be achieved by more accurate source separation of the mixed waste. Utilisation of energy waste had the most significant influence (41-52%) on the total GWP (-880 to -860 kgCO2-eq./t), followed by landfilling of mixed waste (influence 15-23% on the total GWP, 430 kgCO2-eq./t), recycling polyethylene (PE) plastic (influence 18-21% on the total GWP, -1800 kgCO2-eq./t) and recycling cardboard (influence 11-13% on the total GWP, 51 kgCO2-eq./t). A key focus should be placed on treatment processes and substitutions, especially in terms of substitutions of energy waste and PE plastic. This study also clarified the importance of sorting PE plastic, even though the share of this waste fraction was not substantial. The results of this paper were compared to those of previous studies. The output of this analysis indicated that the total GWP can be significantly reduced by identifying an alternative recycling or incineration location for cardboard where it is used to substitute virgin material or replace fossil fuels respectively. In conclusion, it is essential to note that waste management companies have a notable influence on the emissions of commercial waste management because they choose the places at which the waste fractions are treated and utilised. PMID- 29576514 TI - Toward zero waste events: Reducing contamination in waste streams with volunteer assistance. AB - Public festivals and events generate a tremendous amount of waste, especially when they involve food and drink. To reduce contamination across waste streams, we evaluated three types of interventions at a public event. In a randomized control trial, we examined the impact of volunteer staff assistance, bin tops, and sample 3D items with bin tops, on the amount of contamination and the weight of the organics, recyclable containers, paper, and garbage bins at a public event. The event was the annual Apple Festival held at the University of British Columbia, which was attended by around 10,000 visitors. We found that contamination was the lowest in the volunteer staff condition among all conditions. Specifically, volunteer staff reduced contamination by 96.1% on average in the organics bin, 96.9% in the recyclable containers bin, 97.0% in the paper bin, and 84.9% in the garbage bin. Our interventions did not influence the weight of the materials in the bins. This finding highlights the impact of volunteers on reducing contamination in waste streams at events, and provides suggestions and implications for waste management for event organizers to minimize contamination in all waste streams to achieve zero waste goals. PMID- 29576515 TI - Pyrolysis of polystyrene waste in the presence of activated carbon in conventional and microwave heating using modified thermocouple. AB - Pyrolysis process was experimented using two types of heating source, namely conventional and microwave. Polystyrene (PS) plastic waste was used as feedstock in a batch reactor for both the conventional (slow pyrolysis) and microwave pyrolysis. The effect of activated carbon to polystyrene ratio on (i) yield of oil, gas and residues (ii) reaction temperature (iii) reaction time were studied. Quality of oil from pyrolysis of polystyrene were assessed for the possible applicability in fuel production. Microwave power of 450 W and polymer to activated carbon ratio of 10:1, resulted in the highest oil yield of 93.04 wt.% with a higher heating value of 45 MJ kg-1 and a kinematic viscosity of 2.7 cSt. Microwave heating when compared to conventional heating method, exhibits a reaction temperature and time of 330 degrees C in 5.5 min, whereas in conventional heating system it was 418 degrees C in 60 min. The gas chromatography-mass spectrometry analysis of liquid oil from microwave pyrolysis predominantly yields alkenes of 8.44 wt.%, alpha-methyl styrene 0.96 wt.%, condensed ring aromatics 23.21 wt.% and benzene derivatives 26.77 wt.% when the polystyrene to activated carbon ratio was 10:1. Significant factor of using microwave heating is the amount of energy converted (kWh) is lesser than conventional heating. PMID- 29576505 TI - Siponimod versus placebo in secondary progressive multiple sclerosis (EXPAND): a double-blind, randomised, phase 3 study. AB - BACKGROUND: No treatment has consistently shown efficacy in slowing disability progression in patients with secondary progressive multiple sclerosis (SPMS). We assessed the effect of siponimod, a selective sphingosine 1-phosphate (S1P) receptor1,5 modulator, on disability progression in patients with SPMS. METHODS: This event-driven and exposure-driven, double-blind, phase 3 trial was done at 292 hospital clinics and specialised multiple sclerosis centres in 31 countries. Using interactive response technology to assign numbers linked to treatment arms, patients (age 18-60 years) with SPMS and an Expanded Disability Status Scale score of 3.0-6.5 were randomly assigned (2:1) to once daily oral siponimod 2 mg or placebo for up to 3 years or until the occurrence of a prespecified number of confirmed disability progression (CDP) events. The primary endpoint was time to 3 month CDP. Efficacy was assessed for the full analysis set (ie, all randomly assigned and treated patients); safety was assessed for the safety set. This trial is registered with ClinicalTrials.gov, number NCT01665144. FINDINGS: 1651 patients were randomly assigned between Feb 5, 2013, and June 2, 2015 (1105 to the siponimod group, and 546 to the placebo group). One patient did not sign the consent form, and five patients did not receive study drug, all of whom were in the siponimod group. 1645 patients were included in the analyses (1099 in the siponimod group and 546 in the placebo). At baseline, the mean time since first multiple sclerosis symptoms was 16.8 years (SD 8.3), and the mean time since conversion to SPMS was 3.8 years (SD 3.5); 1055 (64%) patients had not relapsed in the previous 2 years, and 918 (56%) of 1651 needed walking assistance. 903 (82%) patients receiving siponimod and 424 (78%) patients receiving placebo completed the study. 288 (26%) of 1096 patients receiving siponimod and 173 (32%) of 545 patients receiving placebo had 3-month CDP (hazard ratio 0.79, 95% CI 0.65 0.95; relative risk reduction 21%; p=0.013). Adverse events occurred in 975 (89%) of 1099 patients receiving siponimod versus 445 (82%) of 546 patients receiving placebo; serious adverse events were reported for 197 (18%) patients in the siponimod group versus 83 (15%) patients in the placebo group. Lymphopenia, increased liver transaminase concentration, bradycardia and bradyarrhythmia at treatment initiation, macular oedema, hypertension, varicella zoster reactivation, and convulsions occurred more frequently with siponimod than with placebo. Initial dose titration mitigated cardiac first-dose effects. Frequencies of infections, malignancies, and fatalities did not differ between groups. INTERPRETATION: Siponimod reduced the risk of disability progression with a safety profile similar to that of other S1P modulators and is likely to be a useful treatment for SPMS.

AB - To mark the centenary of the 1918 influenza pandemic, the broadcasting network BBC have put together a 75-min documentary called 'Contagion! The BBC Four Pandemic'. Central to the documentary is a nationwide citizen science experiment, during which volunteers in the United Kingdom could download and use a custom mobile phone app called BBC Pandemic, and contribute their movement and contact data for a day. As the 'maths team', we were asked to use the data from the app to build and run a model of how a pandemic would spread in the UK. The headline results are presented in the TV programme. Here, we document in detail how the model works, and how we shaped it according the incredibly rich data coming from the BBC Pandemic app. We have barely scratched the depth of the volunteer data available from the app. The work presented in this article had the sole purpose of generating a single detailed simulation of a pandemic influenza-like outbreak in the UK. When the BBC Pandemic app has completed its collection period, the vast dataset will be made available to the scientific community (expected early 2019). It will take much more time and input from a broad range of researchers to fully exploit all that this dataset has to offer. But here at least we were able to harness some of the power of the BBC Pandemic data to contribute something which we hope will capture the interest and engagement of a broad audience. PMID- 29576517 TI - Transmission dynamics of influenza in two major cities of Uganda. AB - In this paper, we report the epidemic characteristics of the three co-circulating influenza viruses (i.e., A/H1N1, A/H3N2, and B) in two tropical African cities Kampala and Entebbe, Uganda-over an eight-year period (2008-2015). Using wavelet methods, we show that influenza epidemics recurred annually during the study period. In most months, two or more influenza viruses co-circulated at the same time. However, the epidemic timing differed by influenza (sub)type. Influenza A/H3N2 caused epidemics approximately every 2 years in both cities and tended to alternate with A/H1N1 or B. Influenza A/H1N1 and B produced smaller but more frequent epidemics and biennial epidemics of these two viruses tended to be synchronous. In addition, epidemics of A/H3N2 were more synchronized in the two cities (located ca.37 km apart) than that of A/H1N1 or influenza B. PMID- 29576518 TI - A critical review on anaerobic digestion of microalgae and macroalgae and co digestion of biomass for enhanced methane generation. AB - Biogas production using algal resources has been widely studied as a green and alternative renewable technology. This review provides an extended overview of recent advances in biomethane production via direct anaerobic digestion (AD) of microalgae, macroalgae and co-digestion mechanism on biomethane production and future challenges and prospects for its scaled-up applications. The effects of pretreatment in the preparation of algal feedstock for methane generation are discussed briefly. The role of different operational and environmental parameters for instance pH, temperature, nutrients, organic loading rate (OLR) and hydraulic retention time (HRT) on sustainable methane generation are also reviewed. Finally, an outlook on the possible options towards the scale up and enhancement strategies has been provided. This review could encourage further studies in this area, to intend and operate continuous mode by designing stable and reliable bioreactor systems and to analyze the possibilities and potential of co-digestion for the promotion of algal-biomethane technology. PMID- 29576519 TI - Percutaneous closure of patent foramen ovale vs. medical treatment for patients with history of cryptogenic stroke: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Patients with history of cryptogenic stroke are more likely to have a patent foramen ovale (PFO) and should be managed with antithrombotic agents, while the alternative option is percutaneous closure of PFOs. Our aim was to perform a meta-analysis of randomized controlled trials (RCTs) comparing percutaneous closure vs. medical treatment for patients with PFO and prior cryptogenic stroke. METHODS: Medline, Scopus and Cochrane databases were reviewed. A random-effect model meta-analysis was used and I-square was utilized to assess the heterogeneity. New ischemic stroke was defined as the primary endpoint. A sensitivity analysis was performed for Amplatzer device. Subgroup analyses were performed for different patient and PFO characteristics for the composite endpoints as defined by the included RCTs. RESULTS: In total of 3440 patients were included in this meta-analysis. Closure devices were superior to medical therapy for prevention of recurrent ischemic strokes (HR = 0.29; CI: 0.02 0.56), but were associated with increased risk of new onset of atrial fibrillation (AF) and atrial flutter (RR = 4.67; CI: 2.22-9.81). However, in the sensitivity analysis for Amplatzer device, there was no difference between the two groups in new onset of atrial arrhythmias. Closure devices were superior across all different subgroups when compared to medical treatment with the exception of patients with a small shunt. CONCLUSION: This meta-analysis shows that closure devices for patients with PFO and history of cryptogenic stroke can significantly decrease the risk of a new ischemic stroke. The use of Amplatzer device was not associated with increased risk of newly diagnosed atrial arrhythmias. PMID- 29576520 TI - Allergic recurrent coronary stent thrombosis: A mini-review of Kounis syndrome. AB - Kounis syndrome (KS) consists of an association between hypersensitivity reactions triggered by various environmental and pharmacological factors and acute coronary syndromes. Blood supply may be compromised by either vasospasm (type I), native plaque destabilization (type II) or stent thrombosis (type III). Although the prognosis is generally favorable, treatment should include aggressive anti-thrombotic and anti-allergic therapies. A case compatible with type III KS, manifested as a macular rash followed by two episodes of stent thrombosis after primary angioplasty (PCI) of the right coronary artery is presented, and complemented by a review on the topic. PMID- 29576521 TI - Relationship between serum levels of oxidative stress and metabolic syndrome components. AB - AIMS: This study aimed to investigate the relationship between the total antioxidant capacity (TAC) and Malondialdehyde (MDA) with number of metabolic syndrome (Mets) components on the personnel working in Shahroud University of Medical Sciences. METHODS: This cross-sectional study was conducted on 167 personnel aged 30-60 years old. ATP III criteria were used to diagnose patients with MetS. Oxidative stress indicators were measured. The data was analyzed via one-way ANOVA, and Pearson and Spearman correlation coefficients. RESULTS: The result showed that TAC had a significant positive correlation with HDL and a significant negative correlation with abdominal obesity. In addition, there was a significant positive association between the level of MDA and age, BMI, abdominal obesity, diastolic blood pressure, triglycerides, and LDL; however, it had a negative significant correlation with HDL. CONCLUSIONS: The measurement of TAC and MDA biomarkers can increase the early diagnosis of patients at risk of developing Mets. PMID- 29576522 TI - Dietary pattern in pregnancy and risk of gestational diabetes mellitus (GDM). AB - AIM: Among the most common metabolic disorders during pregnancy is gestational diabetes mellitus (GDM). This research was conducted to examine the dietary pattern in women with GDM. MATERIAL AND METHODS: In this case-study, 204 pregnant women (104 cases and 100 control women) were chosen through convenient sampling and random sampling. The subjects' food intakes were assessed using semi quantitative food frequency questionnaire, while their activities evaluated by physical activity questionnaire. Anthropometric indices were measured based on standard instructions, and the body mass index was calculated. The dietary patterns were determined using principal component analysis and its relationship with preeclampsia was tested using logistic regression method. RESULTS: Unhealthy and healthy dietary patterns were found among the pregnant women. In the unhealthy group, after modifying the effect of confounding variables, a significant relationship was observed between dietary pattern and having gestational diabetes (OR = 2.838,95% CI:1.039-7.751). In the healthy group, on the other hand, the people in the fourth quartile had 149% and 184% higher chance not to catch gestational diabetes before and after modification with confounders, respectively (OR = 0.284,95% CI:0.096-0.838), when compared with people in the first quartile. CONCLUSION: The findings indicated that selection of foods including fruits, vegetables, low-fat dairies, etc. as healthy dietary pattern is associated with diminished risk of GDM among pregnant women. Determining healthy dietary pattern during pregnancy, considering the foods consumed among pregnant women, as a useful and practical guide during this period can be publicized for training and nutritional interventions. PMID- 29576523 TI - Predictors of metformin failure in gestational diabetes mellitus (GDM). AB - INTRODUCTION AND OBJECTIVE: The role of metformin in gestational diabetes mellitus (GDM) is also increasing. However, almost half of metformin-treated women required additional insulin. Therefore, identifying the characteristics of these women may help define optimal therapeutic strategy. METHODS: This is a retrospective cohort study done in a District General Hospital, UK. GDM was diagnosed by 75 g OGTT test between 24 and 28 weeks of gestation with fasting levels of >=6.1 mmol/l and/or 2 h postprandial (PP) level of >=7.8 mmol/l. Logistic regression and receiver operator curves (ROC) were performed to identify the predictors of metformin failure. RESULTS: Out of 228 women with GDM included, 46/228 (20.2%) and 151/228 (66.2%) received insulin and metformin as first-line medication respectively. Among the metformin-treated, 13 stopped treatment and were excluded from analysis. Of the included 138 metformin-treated women, 77 (55.8%) required supplementary insulin (metformin failure). Metformin failure group had higher maternal age and fasting glucose level at OGTT, HbA1c at OGTT and earlier gestational age (GA) at medication initiation. Metformin failure was predicted if fasting OGTT level >4.8 mmol/l (69% sensitivity and 62% specificity). If the fasting levels of IADPSG (International Association of Diabetes and Pregnancy Study Groups) criteria and NICE (National Institute of Health and Care Excellence) were used, the positive predictive value was 78% and 77% respectively. CONCLUSION: As women with higher fasting glucose levels have higher chance of necessitating insulin in later pregnancies, appropriate addition of insulin at metformin initiation for these women could help better glycaemic control throughout pregnancy.

PMID- 29576524 TI - Association between vitamin D status and metabolic syndrome risk factors. AB - BACKGROUND: The concern with the incidence of chronic-degenerative diseases is increasing worldwide, and many studies have shown that insufficiency of vitamin D (VD) can be linked to several metabolic disorders. AIMS: Thus, the objective of this study was to evaluate the association of the metabolic syndrome risk factors, atherogenic indices and VD in a group of patients attended at a Cardiology Center. METHODS: For this study, we invited 200 patients of both sexes attended in a Cardiology Center (Medical School of Marilia - Sao Paulo - Brazil). Most were female (n = 111) and aged between 41 and 70 years (from march to august, 2017). RESULTS: Our results showed that only 20.0% of the patients presented normal levels of VD. Patients with altered values for this vitamin presented significantly higher values for glycemia, HbA1c, Total cholesterol, LDL c, triglycerides, Castelli Index I, Castelli Index II, Body Mass Index, waist circumference, non-HDL-c and the estimative of the size of the LDL-c particle. Vitamin D correlated negatively with glycemia, HbA1C, triglycerides, atherogenic indices, Body Mass Index, and blood pressure. Multiple Regression Model showed that for an individual to maintain metabolic parameters, at least at borderline values, the levels of VD should be 37.64 that is not in accordance with the reference values. CONCLUSIONS: These results showed a remarkable prevalence of low concentrations of Vitamin D in patients with cardiovascular risk factors. PMID- 29576526 TI - Systematic Characterization of Stress-Induced RNA Granulation. AB - Upon stress, cytoplasmic mRNA is sequestered to insoluble ribonucleoprotein (RNP) granules, such as the stress granule (SG). Partially due to the belief that translationally suppressed mRNAs are recruited to SGs in bulk, stress-induced dynamic redistribution of mRNA has not been thoroughly characterized. Here, we report that endoplasmic reticulum (ER) stress targets only a small subset of translationally suppressed mRNAs into the insoluble RNP granule fraction (RG). This subset, characterized by extended length and adenylate-uridylate (AU)-rich motifs, is highly enriched with genes critical for cell survival and proliferation. This pattern of RG targeting was conserved for two other stress types, heat shock and arsenite toxicity, which induce distinct responses in the total cytoplasmic transcriptome. Nevertheless, stress-specific RG-targeting motifs, such as guanylate-cytidylate (GC)-rich motifs in heat shock, were also identified. Previously underappreciated, transcriptome profiling in the RG may contribute to understanding human diseases associated with RNP dysfunction, such as cancer and neurodegeneration. PMID- 29576528 TI - ZUFSP Deubiquitylates K63-Linked Polyubiquitin Chains to Promote Genome Stability. AB - Deubiquitylating enzymes (DUBs) enhance the dynamics of the versatile ubiquitin (Ub) code by reversing and regulating cellular ubiquitylation processes at multiple levels. Here we discovered that the uncharacterized human protein ZUFSP (zinc finger with UFM1-specific peptidase domain protein/C6orf113/ZUP1), which has been annotated as a potentially inactive UFM1 protease, and its fission yeast homolog Mug105 define a previously unrecognized class of evolutionarily conserved cysteine protease DUBs. Human ZUFSP selectively interacts with and cleaves long K63-linked poly-Ub chains by means of tandem Ub-binding domains, whereas it displays poor activity toward mono- or di-Ub substrates. In cells, ZUFSP is recruited to and regulates K63-Ub conjugates at genotoxic stress sites, promoting chromosome stability upon replication stress in a manner dependent on its catalytic activity. Our findings establish ZUFSP as a new type of linkage selective cysteine peptidase DUB with a role in genome maintenance pathways. PMID- 29576527 TI - Discovery and Characterization of ZUFSP/ZUP1, a Distinct Deubiquitinase Class Important for Genome Stability. AB - Deubiquitinating enzymes (DUBs) are important regulators of ubiquitin signaling. Here, we report the discovery of deubiquitinating activity in ZUFSP/C6orf113. High-resolution crystal structures of ZUFSP in complex with ubiquitin reveal several distinctive features of ubiquitin recognition and catalysis. Our analyses reveal that ZUFSP is a novel DUB with no homology to any known DUBs, leading us to classify ZUFSP as the seventh DUB family. Intriguingly, the minimal catalytic domain does not cleave polyubiquitin. We identify two ubiquitin binding domains in ZUFSP: a ZHA (ZUFSP helical arm) that binds to the distal ubiquitin and an atypical UBZ domain in ZUFSP that binds to polyubiquitin. Importantly, both domains are essential for ZUFSP to selectively cleave K63-linked polyubiquitin. We show that ZUFSP localizes to DNA lesions, where it plays an important role in genome stability pathways, functioning to prevent spontaneous DNA damage and also promote cellular survival in response to exogenous DNA damage. PMID- 29576529 TI - Sequential Enhancer Sequestration Dysregulates Recombination Center Formation at the IgH Locus. AB - Immunoglobulin heavy-chain (IgH) genes are assembled by DNA rearrangements that juxtapose a variable (VH), a diversity (DH), and a joining (JH) gene segment. Here, we report that in the absence of intergenic control region 1 (IGCR1), the intronic enhancer (EMU) associates with the next available CTCF binding site located close to VH81X via putative heterotypic interactions involving YY1 and CTCF. The alternate EMU/VH81X loop leads to formation of a distorted recombination center and altered DH rearrangements and disrupts chromosome conformation that favors distal VH recombination. Cumulatively, these features drive highly skewed, EMU-dependent recombination of VH81X. Sequential deletion of CTCF binding regions on IGCR1-deleted alleles suggests that they influence recombination of single proximal VH gene segments. Our observations demonstrate that EMU interacts differently with IGCR1- or VH-associated CTCF binding sites and thereby identify distinct roles for insulator-like elements in directing enhancer activity. PMID- 29576530 TI - Latest Evidence on the Impact of Smoking, Sports, and Sexual Activity as Modifiable Lifestyle Risk Factors for Prostate Cancer Incidence, Recurrence, and Progression: A Systematic Review of the Literature by the European Association of Urology Section of Oncological Urology (ESOU). AB - CONTEXT: Smoking, sexual activity, and physical activity (PA) are discussed as modifiable lifestyle factors associated with prostate cancer (PCa) development and progression. OBJECTIVE: To evaluate the available evidence concerning the association of smoking, sexual activity, and sports and exercise on PCa risk, treatment outcome, progression, and cancer-specific mortality. EVIDENCE ACQUISITION: A systematic review of studies published between 2007 and 2017 using MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials, and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement criteria was conducted. EVIDENCE SYNTHESIS: While data concerning the impact of smoking on PCa development remain conflicting, there is robust evidence that smoking is associated with aggressive tumor features and worse cancer-related outcome, which seems to be maintained for 10 yr after smoking cessation. Less convincing and limited evidence exists for the association of sexual activity with PCa risk. The findings related to PA and PCa support the inference that exercise might be a useful factor in the prevention of PCa and tumor progression, while it is not finally proved under which specific conditions PA might be protective against disease development. CONCLUSIONS: Smoking is associated with aggressive tumor features and worse cancer-related prognosis; as this negative impact seems to be maintained for 10yr after smoking cessation, urologists should advise men to quit smoking latest at PCa diagnosis to improve their prognosis. As several studies indicate a positive impact of exercise on tumor development, progression, and treatment outcome, it is certainly reasonable to advocate an active lifestyle. Least convincing evidence is available for the interaction of sexual activity and PCa, and well conducted and longitudinal studies are clearly necessary to evaluate whether the suggested associations between PCa risk and sexual behavior are real or spurious. PATIENT SUMMARY: In this systematic review, we looked at the impact of smoking, sexual activity, and sports and exercise on prostate cancer risk and outcome after treatment. While the evidence for sexual activity is not overall clear, we found that smoking might lead to more aggressive cancers and result in worse treatment outcome. Physical activity might prevent prostate cancer and improve cancer-related outcomes as well. Hence, it is certainly reasonable to advocate an active lifestyle and advise men to quit smoking. PMID- 29576531 TI - Copper-Binding Small Molecule Induces Oxidative Stress and Cell-Cycle Arrest in Glioblastoma-Patient-Derived Cells. AB - Transition metals are essential, but deregulation of their metabolism causes toxicity. Here, we report that the compound NSC319726 binds copper to induce oxidative stress and arrest glioblastoma-patient-derived cells at picomolar concentrations. Pharmacogenomic analysis suggested that NSC319726 and 65 other structural analogs exhibit lethality through metal binding. Although NSC319726 has been reported to function as a zinc ionophore, we report here that this compound binds to copper to arrest cell growth. We generated and validated pharmacogenomic predictions: copper toxicity was substantially inhibited by hypoxia, through an hypoxia-inducible-factor-1alpha-dependent pathway; copper bound NSC319726 induced the generation of reactive oxygen species and depletion of deoxyribosyl purines, resulting in cell-cycle arrest. These results suggest that metal-induced DNA damage may be a consequence of exposure to some xenobiotics, therapeutic agents, as well as other causes of copper dysregulation, and reveal a potent mechanism for targeting glioblastomas. PMID- 29576532 TI - Structural Insights into the Forward and Reverse Enzymatic Reactions in Human Adenine Phosphoribosyltransferase. AB - Phosphoribosyltransferases catalyze the displacement of a PRPP alpha-1' pyrophosphate to a nitrogen-containing nucleobase. How they control the balance of substrates/products binding and activities is poorly understood. Here, we investigated the human adenine phosphoribosyltransferase (hAPRT) that produces AMP in the purine salvage pathway. We show that a single oxygen atom from the Tyr105 side chain is responsible for selecting the active conformation of the 12 amino acid long catalytic loop. Using in vitro, cellular, and in crystallo approaches, we demonstrated that Tyr105 is key for the fine-tuning of the kinetic activity efficiencies of the forward and reverse reactions. Together, our results reveal an evolutionary pressure on the strictly conserved Tyr105 and on the dynamic motion of the flexible loop in phosphoribosyltransferases that is essential for purine biosynthesis in cells. These data also provide the framework for designing novel adenine derivatives that could modulate, through hAPRT, diseases-involved cellular pathways. PMID- 29576534 TI - The Homeostatic Force of Ghrelin. AB - Ghrelin, a gastric-derived acylated peptide, regulates energy homeostasis by transmitting information about peripheral nutritional status to the brain, and is essential for protecting organisms against famine. Ghrelin operates brain circuits to regulate homeostatic and hedonic feeding. Recent research advances have shed new light on ghrelin's multifaceted roles in cellular homeostasis, which could maintain the internal environment and overcome metaflammation in metabolic organs. Here, we highlight our current understanding of the regulatory mechanisms of the ghrelin system in energy metabolism and cellular homeostasis and its clinical trials. Future studies of ghrelin will further elucidate how the stomach regulates systemic homeostasis. PMID- 29576533 TI - Dual Modifications of alpha-Galactosylceramide Synergize to Promote Activation of Human Invariant Natural Killer T Cells and Stimulate Anti-tumor Immunity. AB - Glycosylceramides that activate CD1d-restricted invariant natural killer T (iNKT) cells have potential therapeutic applications for augmenting immune responses against cancer and infections. Previous studies using mouse models identified sphinganine variants of alpha-galactosylceramide as promising iNKT cell activators that stimulate cytokine responses with a strongly proinflammatory bias. However, the activities of sphinganine variants in mice have generally not translated well to studies of human iNKT cell responses. Here, we show that strongly proinflammatory and anti-tumor iNKT cell responses were achieved in mice by a variant of alpha-galactosylceramide that combines a sphinganine base with a hydrocinnamoyl ester on C6" of the sugar. Importantly, the activities observed with this variant were largely preserved for human iNKT cell responses. Structural and in silico modeling studies provided a mechanistic basis for these findings and suggested basic principles for capturing useful properties of sphinganine analogs of synthetic iNKT cell activators in the design of immunotherapeutic agents. PMID- 29576535 TI - Metabolic Slowing and Reduced Oxidative Damage with Sustained Caloric Restriction Support the Rate of Living and Oxidative Damage Theories of Aging. AB - Calorie restriction (CR) is a dietary intervention with potential benefits for healthspan improvement and lifespan extension. In 53 (34 CR and 19 control) non obese adults, we tested the hypothesis that energy expenditure (EE) and its endocrine mediators are reduced with a CR diet over 2 years. Approximately 15% CR was achieved over 2 years, resulting in an average 8.7 kg weight loss, whereas controls gained 1.8 kg. In the CR group, EE measured over 24 hr or during sleep was approximately 80-120 kcal/day lower than expected on the basis of weight loss, indicating sustained metabolic adaptation over 2 years. This metabolic adaptation was accompanied by significantly reduced thyroid axis activity and reactive oxygen species (F2-isoprostane) production. Findings from this 2-year CR trial in healthy, non-obese humans provide new evidence of persistent metabolic slowing accompanied by reduced oxidative stress, which supports the rate of living and oxidative damage theories of mammalian aging. PMID- 29576536 TI - gamma-Secretase Inhibition Lowers Plasma Triglyceride-Rich Lipoproteins by Stabilizing the LDL Receptor. AB - Excess plasma triglycerides (TGs) are a key component of obesity-induced metabolic syndrome. We have shown that gamma-secretase inhibitor (GSI) treatment improves glucose tolerance due to inhibition of hepatic Notch signaling but found additional Notch-independent reduction of plasma TG-rich lipoproteins (TRLs) in GSI-treated, as well as hepatocyte-specific, gamma-secretase knockout (L-Ncst) mice, which suggested a primary effect on hepatocyte TRL uptake. Indeed, we found increased VLDL and LDL particle uptake in L-Ncst hepatocytes and Ncst-deficient hepatoma cells, in part through reduced gamma-secretase-mediated low-density lipoprotein receptor (LDLR) cleavage and degradation. To exploit this novel finding, we generated a liver-selective Nicastrin ASO, which recapitulated glucose and lipid improvements of L-Ncst mice, with increased levels of hepatocyte LDLR. Collectively, these results identify the role of hepatic gamma secretase to regulate LDLR and suggest that liver-specific GSIs may simultaneously improve multiple aspects of the metabolic syndrome. PMID- 29576537 TI - Retinal Ganglion Cell Diversity and Subtype Specification from Human Pluripotent Stem Cells. AB - Retinal ganglion cells (RGCs) are the projection neurons of the retina and transmit visual information to postsynaptic targets in the brain. While this function is shared among nearly all RGCs, this class of cell is remarkably diverse, comprised of multiple subtypes. Previous efforts have identified numerous RGC subtypes in animal models, but less attention has been paid to human RGCs. Thus, efforts of this study examined the diversity of RGCs differentiated from human pluripotent stem cells (hPSCs) and characterized defined subtypes through the expression of subtype-specific markers. Further investigation of these subtypes was achieved using single-cell transcriptomics, confirming the combinatorial expression of molecular markers associated with these subtypes, and also provided insight into more subtype-specific markers. Thus, the results of this study describe the derivation of RGC subtypes from hPSCs and will support the future exploration of phenotypic and functional diversity within human RGCs. PMID- 29576538 TI - A Critical Role of TET1/2 Proteins in Cell-Cycle Progression of Trophoblast Stem Cells. AB - The ten-eleven translocation (TET) proteins are well known for their role in maintaining naive pluripotency of embryonic stem cells. Here, we demonstrate that, jointly, TET1 and TET2 also safeguard the self-renewal potential of trophoblast stem cells (TSCs) and have partially redundant roles in maintaining the epithelial integrity of TSCs. For the more abundantly expressed TET1, we show that this is achieved by binding to critical epithelial genes, notably E cadherin, which becomes hyper-methylated and downregulated in the absence of TET1. The epithelial-to-mesenchymal transition phenotype of mutant TSCs is accompanied by centrosome duplication and separation defects. Moreover, we identify a role of TET1 in maintaining cyclin B1 stability, thereby acting as facilitator of mitotic cell-cycle progression. As a result, Tet1/2 mutant TSCs are prone to undergo endoreduplicative cell cycles leading to the formation of polyploid trophoblast giant cells. Taken together, our data reveal essential functions of TET proteins in the trophoblast lineage. PMID- 29576539 TI - A Humanized Mouse Model Generated Using Surplus Neonatal Tissue. AB - Here, we describe the NeoThy humanized mouse model created using non-fetal human tissue sources, cryopreserved neonatal thymus and umbilical cord blood hematopoietic stem cells (HSCs). Conventional humanized mouse models are made by engrafting human fetal thymus and HSCs into immunocompromised mice. These mice harbor functional human T cells that have matured in the presence of human self peptides and human leukocyte antigen molecules. Neonatal thymus tissue is more abundant and developmentally mature and allows for creation of up to ~50-fold more mice per donor compared with fetal tissue models. The NeoThy has equivalent frequencies of engrafted human immune cells compared with fetal tissue humanized mice and exhibits T cell function in assays of ex vivo cell proliferation, interferon gamma secretion, and in vivo graft infiltration. The NeoThy model may provide significant advantages for induced pluripotent stem cell immunogenicity studies, while bypassing the requirement for fetal tissue. PMID- 29576541 TI - Cold stress tolerance in rice: physiological changes, molecular mechanism, and future prospects. AB - Low temperature is a major factor affecting rice geographical distribution growth, development, and productivity. Cold stress mediates a series of physiological and metabolite changes, such as alterations in chlorophyll fluorescence, electrolyte leakage, reactive oxygen species (ROS), malondialdehyde (MAD), sucrose, lipid peroxides, proline, and other metabolites, plant endogenous hormones abscisic acid (ABA) and gibberellin (GA) also changes. In this review, we summarize the recent research progress on physiological and metabolic changes under low temperature, cold stress related loci and QTL reported by map-based cloning and genome-wide association analysis (GWAS), and some molecular mechanisms in response to low temperature in rice. We also discuss the future prospects on breeding cold tolerance varieties of rice. PMID- 29576542 TI - Histone variant H3.3 and its functions in reprogramming. AB - Histones are a class of evolutionarily conserved nuclear proteins. Histone octamer wrapped by DNA sequence forms the nucleosome, the basic building blocks of eukaryotic chromatin. The nucleosomes keep the DNA in a condensed state, maintain the integrity of the genome, and ensure proper DNA replication, transcription, recombination and repair. Nucleosomes can regulate the biological processes of the cell through a number of distinct post-translational modifications (PTMs) and turnovers of histone variants. Although the histone H3 variant H3.3 differs from the canonical histone H3 by only a few amino acids, it could be incorporated into distinct chromatin regions by specific chaperones and exert diverse functions on the chromatin. Importantly, H3.3 is also an essential maternal factor, and plays a key role in cellular reprogramming during fertilization and somatic cell nuclear transfer. In this review, we summarize the structural properties and enrichment pattern of H3.3, and explore the specific chaperones involved in the H3.3-mediated cellular reprogramming. We hope to provide some insights on new means to improve the efficiency of somatic cell reprogramming and lay the foundation for its potential applications.

AB - Human stem cell-derived models of development and neurodegenerative diseases are challenged by cellular immaturity in vitro. Microengineered organ-on-chip (or Organ-Chip) systems are designed to emulate microvolume cytoarchitecture and enable co-culture of distinct cell types. Brain microvascular endothelial cells (BMECs) share common signaling pathways with neurons early in development, but their contribution to human neuronal maturation is largely unknown. To study this interaction and influence of microculture, we derived both spinal motor neurons and BMECs from human induced pluripotent stem cells and observed increased calcium transient function and Chip-specific gene expression in Organ-Chips compared with 96-well plates. Seeding BMECs in the Organ-Chip led to vascular neural interaction and specific gene activation that further enhanced neuronal function and in vivo-like signatures. The results show that the vascular system has specific maturation effects on spinal cord neural tissue, and the use of Organ-Chips can move stem cell models closer to an in vivo condition.

Mammalian spermatozoa undergo a series of complex structural and functional changes in the epididymis to mature and achieve fertilization capacity. Sperm cell maturation is mediated by a complex physiological process, which is synergistically regulated by a large number of transcription factors, hormones and other signaling molecules. In recent years, there is increasing evidence supporting the notion that functional proteins and sRNA (small RNAs) in epididymosomes participate in sperm maturation and fertilization process. In this review, we summarize the biological roles of functional proteins and two major sRNAs (tRNAs and miRNAs) in sperm maturation in epididymosomes, and provide some theoretical guidance and new ideas for treatments of low fertility, infertility and other reproductive diseases in men. PMID- 29576544 TI - The genetic background and application of Down syndrome mouse models. AB - Down syndrome (DS), trisomy chromosome 21 (Hsa21), is the most common genetic disease caused by chromosome aberration in the human genome. Modeling DS in mice has been challenging since the orthologs of Hsa21 genes map to separate segments of three mouse chromosomes, Mmu16, Mmu17, and Mmu10. Although the early Ts65Dn mouse model exhibited various DS phenotypes, the duplicated fragments were randomly generated by ionizing radiation and did not include all Hsa21 orthologs. In 2004, the successful use of the Cre/LoxP recombination technique in chromosomal engineering in the construction of the Ts1Rhr mouse strain solved the problem of duplication of specific chromosome segment, resulting in the establishment of specific DS mouse models with accurate triplication of particular genes and associated phenotypes. In this review, we briefly introduce the different DS mouse models and discuss their advantages and limitations by focusing on the triplication of Hsa21 orthologs and manifestations of DS phenotypes, thereby providing some references for the selection of specific mouse models in DS research. PMID- 29576545 TI - Research progress in machine learning methods for gene-gene interaction detection. AB - Complex diseases are results of gene-gene and gene-environment interactions. However, the detection of high-dimensional gene-gene interactions is computationally challenging. In the last two decades, machine-learning approaches have been developed to detect gene-gene interactions with some successes. In this review, we summarize the progress in research on machine learning methods, as applied to gene-gene interaction detection. It systematically examines the principles and limitations of the current machine learning methods used in genome wide association studies (GWAS) to detect gene-gene interactions, such as neural networks (NN), random forest (RF), support vector machines (SVM) and multifactor dimensionality reduction (MDR), and provides some insights on the future research directions in the field. PMID- 29576546 TI - Co-amplification at lower denaturation temperature-PCR: methodology and applications. AB - Co-amplification at lower denaturation temperature-polymerase chain reaction (COLD-PCR) is a novel form of PCR that selectively denatures and amplifies low abundance mutations from mixtures of wild-type and mutation-containing sequences, enriching the mutation 10 to 100 folds. Due to the slightly altered melting temperature (Tm) of the double-stranded DNA and the formation of the mutation/wild-type heteroduplex DNA, COLD-PCR methods are sensitive, specific, accurate, cost-effective and easy to maneuver, and can enrich mutations of any type and at any position, even unknown mutations within amplicons. COLD-PCR and its improved methods are now applied in cancer, microorganisms, prenatal screening, animals and plants. They are extremely useful for early diagnosis, monitoring the prognosis of disease and the efficiency of the treatment, drug selection, prediction of prognosis, plant breeding and etc. In this review, we introduce the principles, key techniques, derived methods and applications of COLD-PCR. PMID- 29576547 TI - Expression specificity and compensation effect of Ash2l-1/Ash2l-2 in mouse embryonic stem cells. AB - H3K4me3 is an important epigenetic modification that plays a critical role in maintaining self-renewal of mouse embryonic stem cells (mESCs). H3K4me3 is catalyzed mainly by the mixed lineage leukemia (MLL) methyl-transferase complex. ASH2L, a core subunit of the MLL complex, participates in regulating the open state of chromatin in mESCs. There are two isoforms of the ASH2L protein: ASH2L-1 (80 kDa), which only exists in mouse embryonic fibroblasts and ASH2L-2 (65 kDa), which is the predominant isoform in mESCs. The roles of Ash2l-1 and Ash2l-2 in mESCs have not yet been elucidated. In this study, we established Ash2l-1 -/- and Ash2l-2 -/- knockout mESCs using CRISPR/Cas9. Alkaline phosphatase (AP) staining, immunofluorescence staining, and qRT-PCR showed that there were no obvious differences on the expression level of AP and pluripotent transcription factors (Nanog, Oct4, sox2 and Klf4) among Ash2l-1 -/- mESCs, Ash2l-2 -/- mESCs and wild type (WT) mESCs. However, analysis of embryoid body (EB) differentiation showed that the expression level of Snai2 (ectoderm gene) and Gata4 (endoderm gene) in Ash2l-1 -/- EBs was significantly lower than that in WT EBs (P<0.01). Western blotting assay revealed that the expression of ASH2L-2 was significantly increased (P<0.01) in Ash2l-1 -/- mESCs and vice versa. However, there were no obvious differences on the genomic H3K4me3 level among Ash2l-1 -/- mESCs, Ash2l-2 -/- mESCs and WT mESCs. These results indicate that there exist compensation effects between Ash2l-1 and Ash2l-2. Bioinformatic analysis predicted that there were three and 16 potential binding sites for pluripotency transcription factors located in the promoter of Ash2l-1 and Ash2l-2, respectively. Theses transcription factors may mediate the compensation effect between Ash2l-1 and Ash2l-2. Collectively, these results indicate that the compensation effects between Ash2l-1 and Ash2l-2 may be involved in the maintenance of mESCs pluripotency and the regulation of genomic H3K4me3.

AB - With the implementation of the "Education and Training Program for Outstanding Agricultural and Forestry Talents" in our country, our university established the "Outstanding Class" for students majoring in the animal science. We also carried out a series of educational management and curriculum reforms to cultivate students' systematic model of thinking and the ability of technology innovation. In this paper, we designed a comprehensive experiment that focused on analyzing early and late feather genetic traits of chicken. The students initially observed the phenotype of chickens and gradually were led into genetics analysis. We introduced the breeding practice, and guided the students to use genetic theories to breed chick strains of early and late feather traits. The experiment is not only based on the sex-linkage theory and sex determination mechanism, but also molecular genetics technologies, such as genomic DNA extraction, amplification, enzyme digestion and electrophoresis. Conducting this experiment can enhance students' comprehensive analysis ability and professional skills, as well as be beneficial to cultivate their scientific research interests and curiosity on animal sciences. Thus, we integrated the genetics theories into animal breeding practice that meet the requirement of comprehensive applied talents of animal science specialty. The teaching ideas and methods described in this paper can be applied to other biological experiment teaching practice. PMID- 29576549 TI - Incorporation of the delta-subunit into the epithelial sodium channel (ENaC) generates protease-resistant ENaCs in Xenopus laevis. AB - The epithelial sodium channel (ENaC) is a critical regulator of vertebrate electrolyte homeostasis. ENaC is the only constitutively open ion channel in the degenerin/ENaC protein family, and its expression, membrane abundance, and open probability therefore are tightly controlled. The canonical ENaC is composed of three subunits (alpha, beta, and gamma), but a fourth delta-subunit may replace alpha and form atypical deltabetagamma-ENaCs. Using Xenopus laevis as a model, here we found that mRNAs of the alpha- and delta-subunits are differentially expressed in different tissues and that delta-ENaC predominantly is present in the urogenital tract. Using whole-cell and single-channel electrophysiology of oocytes expressing Xenopus alphabetagamma- or deltabetagamma-ENaC, we demonstrate that the presence of the delta-subunit enhances the amount of current generated by ENaC due to an increased open probability, but also changes current into a transient form. Activity of canonical ENaCs is critically dependent on proteolytic processing of the alpha- and gamma-subunits, and immunoblotting with epitope-tagged ENaC subunits indicated that, unlike alpha-ENaC, the delta-subunit does not undergo proteolytic maturation by the endogenous protease furin. Furthermore, currents generated by deltabetagamma-ENaC were insensitive to activation by extracellular chymotrypsin, and presence of the delta-subunit prevented cleavage of gamma-ENaC at the cell surface. Our findings suggest that subunit composition constitutes an additional level of ENaC regulation, and we propose that the Xenopus delta-ENaC subunit represents a functional example that demonstrates the importance of proteolytic maturation during ENaC evolution. PMID- 29576551 TI - Symptoms of Anxiety and Depression in Obese Singaporeans: a Preliminary Study. AB - BACKGROUND: Obesity is a major component of metabolic syndrome and an independent risk factor for various chronic diseases. It is also closely associated with mental illness, and the interaction is complex and multifactorial. This study aimed to estimate the prevalence of anxiety and depressive symptoms among obese Singaporeans. METHODS: Cross-sectional data of 36 male and 47 female obese Singaporeans who had been referred to the weight management clinic of National University Hospital, Singapore, between January 2010 and November 2011 were collected. Obesity was classified according to criteria of the World Health Organization. The extents of anxiety and depressive symptoms were measured using the Hospital Anxiety and Depression Scale. RESULTS: In obese Singaporeans attending the weight management clinic, the prevalence of anxiety symptoms was higher than that of depressive symptoms (28% vs 11%). There was no major socioeconomic difference between obese patients with and without anxiety, or with and without depressive symptoms. CONCLUSION: In obese Singaporeans, anxiety symptoms may be more common than depressive symptoms. Weight management programmes should incorporate anxiety management as part of standard treatment. Early detection and pharmacological and psychological interventions should be implemented. PMID- 29576550 TI - Apolipoprotein-defined lipoprotein subclasses, serum apolipoproteins, and carotid intima-media thickness in T1D. AB - Circulating apolipoprotein-defined lipoprotein subclasses (ADLS) and apolipoproteins predict vascular events in the general and type 2 diabetes populations, but data in T1D are limited. We examined associations of ADLS, serum apolipoproteins, and conventional lipids with carotid intima-media thickness (IMT) measured contemporaneously and 6 years later in 417 T1D participants [men: n = 269, age 42 +/- 6 y (mean +/- SD); women: n = 148, age 39 +/- 8 y] in the Epidemiology of Diabetes Interventions and Complications study, the follow-up of the Diabetes Control and Complications Trial (DCCT). Date were analyzed by multiple linear regression stratified by sex, and adjusted for time-averaged hemoglobin A1C, diabetes duration, hypertension, BMI, albuminuria, DCCT randomization, smoking, statin treatment, and ultrasound devices. In cross sectional analyses, lipoprotein B (Lp-B), Lp-B:C, Lp-B:E+Lp-B:C:E, Apo-A-II, Apo B, Apo-C-III-HP (heparin precipitate; i.e., Apo-C-III in Apo-B-containing lipoproteins), and Apo-E were positively associated with common and/or internal carotid IMT in men, but only Apo-C-III (total) was (positively) associated with internal carotid IMT in women. In prospective analyses, Lp-B, Apo-B, and Apo-C III-HP were positively associated with common and/or internal carotid IMT in men, while Lp-A1:AII and Apo-A1 were inversely associated with internal carotid IMT in women. The only significant prospective association between conventional lipids and IMT was between triacylglycerols and internal carotid IMT in men. ADLS and apolipoprotein concentrations may provide sex-specific biomarkers and suggest mechanisms for IMT in people with T1D. PMID- 29576552 TI - Frontal Theta Asymmetry as a Biomarker of Depression. AB - INTRODUCTION: Electroencephalography (EEG) has been used extensively to study affective disorders. Quantitative spectral analysis of an EEG scan has been used to assess the biological basis of emotional disorders such as depression as well as to investigate biomarkers of affective disorders. Inter-hemispheric asymmetries in both baseline and stimulus-evoked frequencies (alpha, beta, theta, and delta) are potential biomarkers of depression. The role of frontal alpha asymmetry has been established, but other spectral frequencies such as frontal theta remain elusive. We compared the hemispheric differences in frontal theta power in depressed patients and controls before and during listening to music to study the correlation of frontal theta asymmetry with depression. METHODS: To determine whether stimulus-evoked frontal theta asymmetry is a biomarker of depression, we compared 23 patients with mild depression (based on the Hamilton Depression Rating Scale) with 17 age- and sex-matched controls by conducting EEG at rest and after listening to Indian classical music. RESULTS: In controls without depression, the mean frontal theta power of the left hemisphere and frontal theta asymmetry increased significantly during music listening. In depressed patients, frontal theta asymmetry was reversed during music listening. CONCLUSION: Frontal theta asymmetry is a potential biomarker of depression. PMID- 29576553 TI - Self-harm and Suicide Attempts in a Japanese Psychiatric Hospital. AB - OBJECTIVE: Self-harm and attempted suicide are risk factors for suicide in psychiatric hospital in-patients. This study aimed to analyse the circumstances of self-harm and suicide attempts in a Japanese psychiatric hospital so as to improve management and care. METHODS: Incident reports of self-harm and suicide attempts during a 12.4-year period from November 2000 to March 2013 were reviewed. A descriptive analysis was conducted in terms of age, sex, and diagnosis of patients, as well as level, ward, situations, and causes of incidents. RESULTS: During the study period, 90 cases of self-harm and attempted suicide involving 58 patients were reported. The rate of self-harm and suicide attempts was 0.05 per 1000 patient-days. The types of selfharm and suicide attempts included hanging (n = 25), wrist cutting (n = 19), ingestion of foreign objects (n = 17), and others (n = 29). The single case of completed suicide involved hanging, in a patient with schizophrenia. Among 55 patients with relevant data, the most common clinical diagnosis was mood disorder (41.8%), followed by schizophrenia (36.4%). Mood disorder was 3.5 times as prevalent in females as in males (14 vs. 4). Fourteen patients with mood disorder (n = 8) or schizophrenia (n = 6) were repeatedly involved in 46 of 89 cases of self-harm or attempted suicide; 11 were female. One woman with mood disorder attempted suicide 9 times within the same year. The top 3 management and care factors related to self-harm and suicide attempts were failure to adhere to preventive procedures (28%), insufficient therapeutic communication (28%), and difficulty in predicting suicide (20%). CONCLUSION: Self-harm and suicide attempts at this psychiatric hospital occurred at a rate of 0.05 per 1000 patient-days between late 2000 and early 2013. Efforts are needed to increase compliance with suicide prevention procedures and therapeutic communication, so as to improve management and care of psychiatric in-patients and prevent them from committing suicide. PMID- 29576554 TI - Electrocardiographic Monitoring of Psychiatric In-patients Taking Antipsychotic Medications. AB - OBJECTIVE: To assess the adherence to guidelines for electrocardiographic (ECG) monitoring in Hong Kong psychiatric in-patients who have been prescribed antipsychotic medications. METHODS: In-patients who had been prescribed antipsychotic drugs on hospital admission during the baseline audit period of 15 April 2015 to 16 July 2015 and the re-audit period of 28 January 2016 to 30 April 2016 were included. Quality improvement interventions were delivered after the baseline audit. ECG monitoring adherence was categorised as full adherence (ECG before taking antipsychotics), partial adherence (ECG after taking antipsychotics), or non-adherence (no ECG during hospital stay). Overall compliance was defined as full adherence plus partial adherence. RESULTS: The baseline audit and re-audit included 378 and 422 patients, respectively. Overall compliance with ECG monitoring increased significantly from the baseline audit to re-audit (40.2% vs. 69.9%; p < 0.001). Case-doctors having the grade of resident was associated with stronger adherence to ECG monitoring in both audits. CONCLUSION: Adherence to ECG monitoring guidelines for in-patients who are prescribed antipsychotic drugs is low in Hong Kong, and junior doctors (residents) demonstrate stronger adherence than moresenior doctors. PMID- 29576555 TI - A systematic experimental study of parameters influencing 131-iodine in vivo spectroscopic measurements using age-specific thyroid phantoms. AB - In case of nuclear accident, the internal exposure monitoring of the population will preferably focus on the detection of 131I in the thyroid by in vivo monitoring. In most cases, the calibration of in vivo monitoring is performed with an adult thyroid phantom, which raises doubts regarding the relevance of child exposure assessment. In this study, the influence on the calibration of the thyroid volume, the counting distance and the positioning variations are studied experimentally in a systematic way. A NaI and a germanium detector along with a realistic age-specific set of four thyroid phantoms were used to carry out this study. The thyroid phantom volumes correspond to the following ages: 5, 10, 15 and adult. It was found that the counting efficiency varies linearly with the thyroid volumes for both detectors and whatever the phantom-detector distance is. The variation in counting distance strongly influences the measurement. Whatever the thyroid volume, a 30% difference in efficiency was found between the measurement at the contact and 1 cm for the NaI detector. A mathematical model giving the variation of the counting efficiency as a function of phantom-detector distance is provided. The study of positioning uncertainty has shown that the lateral/vertical displacements induce negligible efficiency variations and that it is relatively independent of the thyroid volume. The counting distance is a major parameter, which must be considered to assess the uncertainty of the subjects' measurements. The data reported here might serve to extract useful orders of magnitude when similar detectors are used. For other detectors, a similar trend might be expected and the information provided here could reduce the amount of experimental work needed to obtain it.

AB - As human beings we live our lives simultaneously in two realms: the realm of problems, and the realm of mysteries. Each of these realms is associated with a different way of seeing, interpreting, and responding to the phenomena we encounter and experience in our lives, including the phenomenon of aging. This essay elaborates on the distinction between problems and mysteries as realms of thinking, feeling, and acting in the world, and applies this distinction to three aspects of the care of the elderly: delaying the aging process, dementia, and managing dying. PMID- 29576558 TI - Primary Prevention with a Capital P. AB - The survival of large segments of human populations to advanced ages is a crowning achievement of improvements in public health and medicine, but in the 21st century, our continued desire to extend life brings forth a unique dilemma. The risk of death from chronic fatal diseases has declined, but even if it continues to do so in the future, the resulting longevity benefits are likely to diminish. It is even possible that unhealthy life expectancy could rise in the future as major fatal diseases wane. The reason for this is that the longer we live, the greater the influence of biological aging on the expression of fatal and disabling diseases. Research in gerontology has already demonstrated that aging is inherently modifiable, and that a therapeutic intervention that slows aging in people is a plausible target for science and public health. Given the speed with which population aging is progressing and chronic fatal and disabling conditions are challenging health-care costs across the globe, the case is now being made that delayed aging could be one of the most efficient and promising ways to combat disease, extend healthy life, compress morbidity, and reduce health-care costs.

AB - Along with many others who have done research and writing on aging over the years, I was drawn to the topic by its social and economic importance. I could not help realizing in some vague way that I would one day become old myself. That thought tended to get brushed away, pushed under the rug along with other stray musings. All that began to change when I hit my 80s, intensifying even more as I went from 85 to 87. I was given an intensified introduction to doctors, disease, operations, and scans-and fear and anxiety. I also lost all interest in writing, my favorite activity. This is my story, which fortunately required writing. PMID- 29576560 TI - Serving the Very Sick, Very Frail, and Very Old: Geriatrics, Palliative Care, and Clinical Ethics. AB - How can we provide the best care for growing numbers of very frail, very sick, or very old people? The disciplines of geriatrics, palliative care, and clinical ethics each have a good deal to offer to improve care for elders, yet each field is saddled with heavy historical baggage. Using a case as a springboard, we address specific strengths and shortcomings of each field, and what these disciplines can learn from each other. Geriatrics is currently largely focused on prevention of disability, cognitive impairment, and death; it should reorganize around a palliative approach to providing care for elders living with multiple chronic conditions, disability, and dementia. Palliative care, while paying some attention to the spectrum of advanced illness, concentrates primarily on cancer; it should expand its central purpose to include providing supportive care to elders with serious illness and their caregivers. Ethics committee members and consultants principally stress individual autonomy; they need to expand their approach and develop longitudinal relationships with patients and family members, routinely incorporating them in deliberations and the crafting of recommendations. However, improving these three disciplines will only go so far toward improving the care of very frail, very sick, or very old people. What is most needed is longitudinal care provided by interdisciplinary primary care teams steeped in the core principles of all three disciplines. PMID- 29576561 TI - Organizing Eldercare for Geographic Communities. AB - The dramatically increasing prevalence of elderly persons disabled by conditions associated with aging could motivate reexamination of service delivery and financing for this population, seeking quality, reliability, and efficiency. Research and innovation have established many components of effective reforms, such as patient-directed care planning, encouragement of volunteer networks and family caregiving, mobilizing services to the home, adhering to patient goals and priorities, limiting poly-pharmacy, reducing the risk of falls, and providing adequate support services for people with disabilities. However, none have become widespread and rarely, if ever, are all of the evidence-based improvements available to a particular disabled elder. This essay argues that reform for disabled elders should be anchored in geographic communities, with a new organizational entity having responsibility for measuring performance and implementing improvements. This entity would use data and public input to set priorities, test improvement strategies, and take steps to assure adequate workforce and service supply. In this MediCaring Community, sustaining finances could come from local taxes or capturing the savings in Medicare that arise with optimal comprehensive services. Generating a new structure to monitor and manage eldercare services for a geographic community would be readily accomplished in some communities and would be worth testing. PMID- 29576562 TI - Merchants of Health: Shaping the Experience of Illness Among Older People. AB - Despite nearly universal health-care coverage for older Americans, the quality of care for the sickest and frailest remains sub-optimal. Understanding why requires analysis of the medical ecosystem. This paper considers the role of four of the principal actors in this system: physicians, hospitals, drug companies, and Medicare. Physicians spend more time in the office addressing diabetes and hypertension than they do evaluating falls and impaired cognition because of their training and their interests. Hospital administrators affect the hospital experience by investing in procedural specialties at the expense of low-tech, high-touch care. Pharmaceutical companies affect the medications older patients take by direct-to-consumer advertising and marketing to physicians. Medicare affects the patient's experience by prospective payment for hospitals, resulting in the burgeoning of post-acute care to accommodate early hospital discharges. Determining how to improve the quality of care for older people requires identifying a lever that affects the entire system. Medicare is uniquely positioned to serve this role. Reforming Medicare by introducing cost effectiveness criteria for reimbursement of expensive devices, by instituting requirements that medical resident training programs include exposure to multidisciplinary team care, and by introducing a new benefit package for the frail elderly could improve American geriatric care. PMID- 29576563 TI - "Losing My Self": A Poet's Ironies and a Daughter's Reflections on Dementia. AB - What can we learn about the experience of dementia and about ways of being human when a poet describes her forgetting? My mother, the poet Shirley Kaufman, died in 2016 at the age of 93. She had dementia for many years. By her mid-80s, many of her poems probed the experience of forgetting, including questions about the nature of self, memory, and thought, and the location of the past and the future. Her experience of forgetting revealed in her ninth and last collection, the widely acclaimed Ezekiel's Wheels (2009), serves as my entry point for an exploration of the self as it becomes dislocated in time yet remains attuned to and consciously aware of that dislocation. That dual quality of my mother's experience is the central, ironic tension explored in this essay. An intimate ethnography, this essay connects my mother's late-life poetry with my own experience, both as a daughter who watched her mother's state of mind unfold and as an anthropologist with extensive experience studying aging, late-life identity, illness, and the culture of medicine. Through the insights of my mother's poetic language I show how dementia can expose ironic features of selfhood, communication, and life itself that are worth our discernment. My hope is that my analysis may focus our gaze on the inherent tension in this form of life and teach us something new about identity, memory, and what is shared among us, those with and without the condition we call dementia. PMID- 29576564 TI - Cognitive Aging: What We Fear and What We Know. AB - Advances in the scientific understanding of the aging brain have led to the concept of cognitive aging. Physicians lag in their understanding of cognitive aging, and the public fear of mental deterioration is disproportionate to its true risk. Understanding cognitive aging requires recognition of its biological underpinnings and the functional changes which may result, as well as the variability across individuals through time and within individuals across different cognitive functions such as memory, knowledge, and reaction time. While there is no magic pill such as a vitamin that has been shown to improve our cognition in later life, several factors that are important well before the age of 65 impact subsequent cognitive aging, including education and a lifelong interest in cognitive stimulating activities. Sufficient evidence exists to recommend three interventions in later life: exercise, reducing cardiovascular risk factors, and careful attention to medications. Acceptance of the new paradigm of cognitive aging is essential to promote the quality of life of older people and will have repercussions throughout society.

PMID- 29576566 TI - Social Determinants of Health at Older Ages: The Long Arm of Early and Middle Adulthood. AB - This article discusses the impacts of midlife social exposures on health in later life, especially for women. Of particular interest is the period of early adulthood. Social epidemiology and life course frameworks help reveal how workplace exposures, family dynamics, and public policies related to work and family shape opportunities in midlife that have long-run health consequences. This is especially important for American women, who have experienced health disadvantages over the last decades compared to women in similarly advanced industrialized countries. In most countries, single women are especially at high risk for poor health at older ages, and job strain can elevate future risks particularly for this subpopulation. Public policies such as maternity leave can reduce risks for poor mental health outcomes among working mothers 30 to 40 years after childbirth, suggesting that the period of early and middle adulthood may influence health trajectories well into old age.

As the plot unfolds, Bell is an aging, increasingly ineffectual cowboy lawman who retires, renounces the violence that sustained his male dominance, and loses the moral certainty that ensured his identity. Like Bell, most old men struggle with four interrelated challenges as they move along the ever-lengthening journey of life: relevance, masculinity, love, and meaning.

AB - Accurate impressions are essential in fabri-cating dental restorations and fixed dental prostheses. During the last decade, digital impression systems have improved substantially. This review discusses the accuracy of digital impression systems for fabrication of dental restorations and fixed dental prostheses. A literature search in PubMed was performed for the period from July 2010 through June 2017. The search keywords were Cerec, digital impression, direct digitalization, indirect digitalization, and intraoral scanner. Only relevant studies are summarized and discussed in this review. In general, the latest systems have considerably reduced the time required for impression making, and the accuracy and marginal fit of digital impression systems have recently improved. Restorations and fixed dental prostheses fabricated with currently available digital impression systems and intraoral scanners exhibit clinically acceptable ranges of marginal gap in both direct and indirect procedures.

AB - The purpose of the present study was to evaluate periodontal health status in children with sickle cell disease (SCD). Forty-nine children with SCD and 39 systemically healthy sex- and age-matched children were enrolled in the study. Plaque index, gingival index, bleeding on probing, pocket depth, salivary volume, and hyperplastic index were recorded. In addition, the histopathological evaluation of gingiva was made in a child with SCD. There were significant differences between the groups with regard to hyperplastic index (P < 0.05), whereas there were no differences in other parameters. Gingival enlargement was detected in 27 children (55.1%) in the SCD group and 6 children (15.4%) in the control group (P < 0.001). However, there were no differences in periodontal health status of children in the SCD and control groups, the most important finding of this study that the gingival enlargement was more prevalent in children with SCD. Sickling and chronic inflammation seen in SCD may affect gingival tissues. Therefore, physicians and dentists must be aware of the effects of SCD on gingival tissues.

AB - The aim of the present cohort study was to compare oral carriage of Candida in waterpipe smokers (WS), cigarette smokers (CS), and non-smokers (NS). A total of 141 individuals (46 WS, 45 CS, and 50 NS) were included. A questionnaire was used to gather demographic information and data on the daily frequency and duration of smoking habits, the reasons for smoking, and daily oral hygiene maintenance habits. Oral Candida (C.) samples were cultured and yeast species were identified using polymerase chain reaction. Unstimulated whole salivary flow rate (UWSFR) was also recorded. The numbers of missing teeth (MT) were counted and tongue lesions were clinically identified. C. albicans was the most prevalent yeast species isolated from all groups. Oral C. albicans carriage was higher among WS (P < 0.05) and CS (P < 0.05) than among NS. Oral C. tropicalis carriage, age, UWSFR and the number of MT were comparable among the groups. Oral Candida carriage was significantly higher among WS and CS than among NS. Therefore it appears that WS and CS are at an increased risk of developing oral candida infections. PMID- 29576572 TI - Effect of demineralization time on the mineral composition and mechanical properties of remineralized dentin. AB - The aim of this study was to determine whether recovery of mineral levels restored the mechanical properties of dentin subjected to different durations of demineralization. Dentin at the floor of class 1 cavities (n = 12) was demineralized for 1, 2, and 3 weeks. Half the demineralized cavity floor was coated (control side), and a Fuji IX restoration was placed. The remaining half was therefore in contact with the Fuji IX restoration (test side). Simulated dentin tubular fluid was then supplied to each pulp chamber for 6 weeks. After remineralization, the teeth were detached from the system and sectioned. Concentrations of calcium, phosphorus, fluorine, and strontium and mechanical properties (hardness and Young's modulus) of the test and control sides were determined by electron probe microanalysis and nano-indentation, respectively. For remineralized dentin demineralized for 1 week, the substantial uptake of mineral elements restored hardness and Young's modulus at depths of 50 to 200 MUm from the lesion front. For longer periods of demineralization (2 and 3 weeks), structural damage to the demineralized dentin was severe and impeded recovery of mechanical properties, despite mineral uptake. PMID- 29576573 TI - Diagnostic reliability of 3.0-T MRI for detecting osseous abnormalities of the temporomandibular joint. AB - We compared the diagnostic reliability of 3.0-T magnetic resonance imaging (MRI) for detection of osseous abnormalities of the temporomandibular joint (TMJ) with that of the gold standard, cone-beam computed tomography (CBCT). Fifty-six TMJs were imaged with CBCT and MRI, and images of condyles and fossae were independently assessed for the presence of osseous abnormalities. The accuracy, sensitivity, and specificity of 3.0-T MRI were 0.88, 1.0, and 0.73, respectively, in condyle evaluation and 0.91, 0.75, and 0.95 in fossa evaluation. The McNemar test showed no significant difference (P > 0.05) between MRI and CBCT in the evaluation of osseous abnormalities in condyles and fossae. The present results indicate that 3.0-T MRI is equal to CBCT in the diagnostic evaluation of osseous abnormalities of the mandibular condyle. PMID- 29576574 TI - Efficiency of light curing units in a government dental school. AB - The light intensity of a light-curing unit is a crucial factor that affects the clinical longevity of resin composites. This study aimed to investigate the efficiency of light-curing units in use at a local governmental dental school for curing conventional and bulk-fill resin materials. A total of 166 light-curing units at three locations were examined, and the brand, type, clinic location, diameter of curing tip, tip cleanliness (using a visual score), and the output (in mW/cm2 using a digital radiometer) were recorded. Only 23.5% of the units examined had clean tips, with the graduate student clinical area containing the highest percentage of clean tips. Further, tips with poor cleanliness score values were associated with significantly lower output intensities. A small percentage (9.4%) of units was capable of producing intensities higher than 1,200 mW/cm2 and lower than 600 mW/cm2 (7.6%). The majority of the low intensity units were located in the undergraduate student area, which also contained the highest number of units with intensities between 900 and 1,200 mW/cm2. The output of all the units in service was satisfactory for curing conventional resin composites, and most units were capable of curing bulk-fill resin materials. PMID- 29576575 TI - Cone-beam computed tomographic evaluation of changes in maxillary alveolar bone after orthodontic treatment. AB - This study examined the relationship of vertical and horizontal changes in the alveolar bone crest with upper incisor movement after orthodontic treatment. Tooth movement was measured on lateral cephalograms. Vertical and horizontal changes in the median alveolar crest and distance from the cementoenamel junction and anterior nasal spine to the alveolar crest were measured with cone-beam computed tomography. The incisal edge moved distally, and the cervical point intruded significantly and moved distally. The median alveolar crest decreased by 3.80 +/- 2.05 mm. The distance from the labial cementoenamel increased significantly, by 0.35 +/- 0.38 mm. The vertical distance from the anterior nasal spine decreased significantly, and the alveolar crest moved distally. Vertical tooth movement was positively associated with change in the distance from the labial cementoenamel junction and inversely associated with vertical change in the distance from the anterior nasal spine on the labial and palatal sides. Lingual tooth movement was positively and negatively correlated with horizontal changes in the labial and palatal alveolar crest and vertical change in the palatal alveolar crest. The lingual movement of incisors was related to labial bone resorption. Greater lingual and extrusive movement of incisors led to a greater decrease in the alveolar bone crest. PMID- 29576576 TI - Successful conservative treatment of jaw osteonecrosis caused by denosumab in patients with multiple bone metastasis. AB - We report a case of osteonecrosis of the jaw (ONJ) associated with denosumab therapy in a 62-year-old female patient being treated for bone metastases from breast cancer. Upon initial presentation at the Department of Oral Medicine, Hokkaido University Hospital, the patient's mandibular molar teeth were extracted because of severe periodontal disease. Two months later, epithelialization of the sockets was observed and treatment with anti-resorptive drugs was started for bone metastases. One year after tooth extraction, bone exposure in the right lower first molar region was observed, and stage 2 medication-related ONJ (MRONJ) was diagnosed. Up to this time, the patient had received zoledronic acid twice and denosumab 22 times. Denosumab was discontinued by the oncologist, and oral antibiotics with rinsing of the exposed bone area were prescribed. By 36 weeks after discontinuation of denosumab, a sequestrum in the posterior part of the mandible was naturally shed, and the site was healed. Bisphosphonate is deposited in bones, whereas denosumab functions extracellularly and circulates in the blood. The effect of denosumab on bone remodeling is reversed shortly after the drug has been discontinued.

PMID- 29576578 TI - Release of antimicrobial compounds from a zinc oxide-chelate cement. AB - This study examined the release of cetylpyridinium chloride and benzalkonium chloride from fatty acid chelate temporary dental cement and their antimicrobial effects. The cement was Cavex Temporary, and either cetylpyridinium chloride or benzalkonium chloride was added (1% or 5% by mass), incorporating into the base paste. Release of the additives was determined by reverse-phase high-performance liquid chromatography. Possible chemical interactions between the cement components and additives were examined by Fourier transform infrared (FTIR) spectroscopy. Antimicrobial effects were assessed by measuring the zone of inhibition around sample discs after 24 h in a Streptococcus mutans culture. FTIR spectroscopy showed no interaction with cement components. For both additives, release was by diffusion for approximately the first 6 hours, with equilibration after about 2 weeks. Diffusion coefficients were 1.76 m2 s1/2 to 8.05 * 10-12 m2 s1/2 and total release was 10.3 to 44.7% of additive loading. Zones of inhibition with additive were significantly larger than those for control discs. In conclusion, the antimicrobial properties of Cavex temporary cement are improved by the addition of the antimicrobial compounds cetylpyridium chloride and benzalkonium chloride, which are released by a diffusion process. PMID- 29576579 TI - Resonance frequency analysis of miniscrew implant stability. AB - This study used resonance frequency (RF) analysis to assess miniscrew implant (MSI) stability during wound healing in a sample of 68 patients (41 women, 27 men; mean age, 27.7 years). The 104 MSIs included 66 placements in the buccal shelf (BS; 2.0 * 12 mm) and 38 placements in interradicular (IR; 1.5 * 8 mm) sites. Thirteen (12.5%) of the MSIs failed. A new RF detection device was used to measure RF at baseline (T0) and at 3 (T1), 6 (T2), 9 (T3), 12 (T4), and 15 (T5) weeks after placement. A linear mixed-effects model was fitted to change in RF values. As compared with the BS group, the IR group had significantly lower RF values on the right side from T0 through T4 and on the left side from T0 through T2. Insertion site and time of visit were significantly associated with RF value. The effects of time of visit significantly differed between the BS and IR sites. Starting from T0, the MSIs placed at both sites had significantly lower RF values at all intervals, except for T0-T1. Future studies should examine how the present clinical protocols can optimize timing of MSI loading to maximize the success rate. PMID- 29576580 TI - In vitro cytotoxic evaluation of novel fast-setting calcium silicate cement compositions and dental materials using colorimetric methyl-thiazolyl-tetrazolium assay. AB - A novel fast-setting calcium silicate cement with fluoride (CSC) has been developed for potential application in tooth crowns. This study compared the cytotoxicity of CSC compositions and a variety of dental materials. We tested CSC compositions (Protooth), MTA, Biodentine, Ketac Molar, Fuji II LC, Vitrebond, DeTrey Zinc, Dycal, and IRM, DMEM (negative control) and 1% NaOCl (positive control). After setting of cements for 24 h, specimens were immersed in DMEM for 24 h to obtain material elutes. The elutes were serially diluted in serum-free DMEM to obtain three dilutions. L929 mouse fibroblast cells (1 * 104 cells per well) were treated for 24 h with elute dilutions (n = 3). Cytotoxicity was determined using methyl-thiazolyl-tetrazolium assay in triplicate. CSC compositions, MTA, and Biodentine showed no significant reduction in cell viability compared to DMEM. There was no significant difference in cell viability, at any of three dilutions, between CSC compositions and either MTA or Biodentine. Cytotoxicity was significantly lower for CSC compositions than for Vitrebond, DeTrey Zinc, Dycal, IRM, and 1% NaOCl, at all three dilutions, and undiluted Fuji II LC elute. In contrast to resin-modified glass ionomers, zinc phosphate cements, Dycal, and IRM, the CSC compositions showed no cytotoxic potential. PMID- 29576581 TI - Aggressive periodontitis presents a higher degree of bilateral symmetry in comparison with chronic periodontitis. AB - The purpose of this cross-sectional study was to evaluate the occurrence of bilateral symmetry in the distribution of clinical parameters in subjects with generalized aggressive periodontitis (GAP) and severe chronic periodontitis (SCP). The sample comprised 53 subjects with GAP and 33 with SCP. Probing depth (PD) and clinical attachment loss (CAL) were recorded from both buccal and lingual interproximal sites of incisors and molars. The symmetry of periodontal destruction was analyzed in terms of intraclass coefficient correlations (ICC) for pairs of contralateral sites at which PD and/or CAL was >=5 mm at one of the sites of the subjects in each group. GAP patients had a higher proportion of both PD and CAL >= 5 mm and also a higher mean proportion of subjects having PD and/or CAL >= 5 mm at one or both sites. The GAP group had 20 pairs of contralateral sites with PD (ICC = 0.22-0.63) and 26 pairs with CAL (ICC = 0.20-0.63), the correlation being statistically significant, while the SCP group had only 2 pairs (ICC = 0.36-0.48) with PD and 5 pairs with CAL (ICC = 0.33-0.58) showing a significant correlation. It can be concluded that GAP shows more symmetric periodontal destruction than SCP. PMID- 29576582 TI - The Reliability of Reduced Field-of-view DTI for Highly Accurate Quantitative Assessment of Cervical Spinal Cord Tracts. AB - PURPOSE: To compare the accuracy of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values between reduced FOV or so-called zonally oblique multislice (ZOOM) and conventional diffusion tensor imaging (DTI) in the cervical spinal cord. METHODS: Both ZOOM and conventional DTI were performed on 10 healthy volunteers. Intraclass correlation coefficient (ICC) was used to evaluate the reliability of the measurements obtained. Four radiologists evaluated the FA and ADC values at each cervical cord level and classified the visibility by 4 ranks. The geometric distortion ratios of the long axis and short axis were compared between ZOOM and conventional DTI. The imaging parameters were as follows: b-value = 600 s/mm2; TR = 4500 ms; TE = 81 ms; FOV = 70 * 47 mm2 / 200 * 200 mm2; matrix = 80 * 51 / 128 * 126 (ZOOM and conventional DTI, respectively). The region of interest was carefully drawn inside the spinal cord margin to exclude the spinal cord component, without excluding the white matter fiber tracts. RESULTS: The average FA value decreased in both ZOOM and conventional DTI in lower spinal cord levels; in contrast, the ADC value increased in lower spinal cord levels. Zonally oblique multislice DTI was superior to conventional DTI with regard to inter-rater and intra-rater reliability; further, visibility was better and the standard deviation was smaller in ZOOM DTI. On both the long and short axis, the geometric distortion ratio was lower in ZOOM DTI at all cervical spinal cord levels compared with the conventional DTI. There was a significant difference in the distortion ratios of the long and short axis between ZOOM and conventional DTI. CONCLUSION: Conventional DTI is unreliable owing to its susceptibility to the surrounding magnetic field. ZOOM DTI is reliable for performing highly accurate evaluations. PMID- 29576583 TI - Clinofibrate improved canine lipid metabolism in some but not all breeds. AB - The objectives of this study were to assess if Clinofibrate (CF) treatment improved lipid metabolism in dogs, and to clarify whether its efficacy is influenced by canine characteristics. We collected medical records of 306 dogs and performed epidemiological analyses. Lipid values of all lipoproteins were significantly decreased by CF medication, especially VLDL triglyceride (TG) concentration (mean reduction rate=54.82%). However, 17.65% of dogs showed drug refractoriness in relation to TG level, and Toy Poodles had a lower CF response than other breeds (OR=5.36, 95% CI=2.07-13.90). Therefore, our study suggests that genetic factors may have an effect on CF response, so genetic studies on lipid metabolism-related genes might be conducted to identify variations in CF efficacy. PMID- 29576584 TI - Oral Fat Sensitivity Is Associated with Social Support for Stress Coping in Young Adult Men. AB - Oral fat sensitivity (OFS), the ability to taste fat, is associated with eating habits in humans, including daily fatty food consumption; namely, proper OFS is important for health. In addition, lifestyle factors, such as stress and sleep, may affect fat intake. However, correlations between OFS, stress management, and sleep are largely unknown. Thus, we investigated the associations of OFS with lifestyle factors regarding stress management and daytime sleepiness in healthy young adult men. We measured OFS, sensitivities for three prototypical tastes (sweet, salty, and sour), and BMI in 22 subjects (27.2 +/- 6.0 years), who also completed a self-reported questionnaire on health, including lifestyle-related questions. The correlations of taste sensitivities with stress management and daytime sleepiness were analyzed. We thus found that the number of mentors for personal concerns (a question regarding stress management, social support) was positively associated with OFS (P = 0.041), but not the other taste sensitivities. In contrast, other lifestyle factors related to stress management (frequency of relaxation, frequency of eating when irritated or worried, and degree of satisfaction with one's sleep) and daytime sleepiness were not significantly associated with OFS, similar to that observed for other tested taste sensitivities. These results characterize the unique association of OFS with the degree of social support in healthy young men and provide novel insights into the nature of individual OFS differences. Thus, measuring the degree of social support may be helpful for the evaluation of OFS impairment, thereby contributing to the prevention of stress-induced overeating. PMID- 29576585 TI - Interleukin-35 as a New Biomarker of Renal Involvement in Lupus Nephritis Patients. AB - Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease with a wide range of clinical presentations. Lupus nephritis (LN) is the most serious manifestation of SLE. Interleukin-35 (IL-35), a member of the interleukin 12 family, has been identified as a novel anti-inflammatory cytokine. In the past ten years, the role of IL-35 in inflammatory and autoimmune diseases has been studied extensively. Serum IL-35 levels, however, have not been studied in LN patients. The aim of the study was to determine serum IL-35 levels in SLE patients with and without nephritis, and their clinical values. The study was carried out on 120 SLE patients, which comprised 80 LN patients and 40 SLE patients without nephritis. SLE disease activity was measured according to Systemic Lupus Erythematosus Disease Activity Index-2 k (SLEDAI-2 k). Statistical evaluation was based on Mann-Whitney U-test, t-test, chi-square test, Spearman rank correlation test and Pearson's correlation test. The result showed that active SLE patients (n = 65) have lower serum IL-35 levels, compared to inactive SLE patients (n = 55, P < 0.001). Furthermore, serum IL-35 levels were significantly lower in LN patients (n = 80) than SLE patients without nephritis (n = 40, P = 0.013). Serum IL-35 levels had significant correlations with SLEDAI 2k (r = -0.626, P < 0.001) in SLE patients and estimated glomerular filtration rate (eGFR) (r = 0.348, P = 0.002) in LN patients. These results indicate that IL 35 is a potential biomarker of renal involvement in LN patients. PMID- 29576586 TI - Local Flow Patterns After Implantation of Bioresorbable Vascular Scaffold in Coronary Bifurcations - Novel Findings by Computational Fluid Dynamics. AB - BACKGROUND: Development of methods for accurate reconstruction of bioresorbable scaffolds (BRS) and assessing local hemodynamics is crucial for investigation of vascular healing after BRS implantation.Methods and Results:Patients with BRS that crossed over in a coronary bifurcation were included for analysis. Reconstructions of the coronary lumen and BRS were performed by fusion of optical coherence tomography and coronary angiography generating a tree model (TM) and a hybrid model with BRS (TM-BRS). A virtual BRS model with thinner struts was created and all 3 models were analyzed using computational fluid dynamics to derive: (1) time-average shear stress (TASS), (2) TASS gradient (TASSG), which represents SS heterogeneity, and (3) fractional flow reserve (FFR). Reconstruction of the BRS was successful in all 10 patients. TASS and TASSG were both higher by TM-BRS than by TM in main vessels (difference 0.27+/-4.30 Pa and 10.18+/-27.28 Pa/mm, P<0.001), with a remarkable difference at side branch ostia (difference 13.51+/-17.40 Pa and 81.65+/-105.19 Pa/mm, P<0.001). With thinner struts, TASS was lower on the strut surface but higher at the inter-strut zones, whereas TASSG was lower in both regions (P<0.001 for all). Computational FFR was lower by TM-BRS than by TM for both main vessels and side branches (P<0.001). CONCLUSIONS: Neglecting BRS reconstruction leads to significantly lower SS and SS heterogeneity, which is most pronounced at side branch ostia. Thinner struts can marginally reduce SS heterogeneity. PMID- 29576589 TI - Contributions of UBE2C and UBE2S to meiotic progression of porcine oocytes. AB - Vertebrate oocytes arrested at the first meiotic prophase must proceed to the second meiotic metaphase (MII) before fertilization. This meiotic process requires the precise control of protein degradation. Part of the protein degradation in oocytes is controlled by members of the ubiquitin-conjugating enzyme family, UBE2C and UBE2S, which are known to participate in mono ubiquitination and poly-ubiquitination, respectively. Although UBE2 enzymes have been well studied in mitosis, their contribution to mammalian oocyte meiosis is relatively unknown and has been studied only in mice. Here, we investigated the contribution of UBE2C and UBE2S to porcine oocyte maturation using an RNA injection method. Overexpression of UBE2S prevented MII arrest of oocytes and led to the formation of a pronucleus (PN) at 48 h of culture. This effect was also observed for prolonged cultures of UBE2C-overexpressing oocytes, suggesting the effectiveness of poly-ubiquitination in the rapid escape from M-phase in porcine oocytes. Although the inhibition of either UBE2C or UBE2S by antisense RNA (asRNA) injection had no effect on oocyte maturation, asRNA-injected oocytes showed inhibited PN formation after parthenogenetic activation. These results indicated that ubiquitination of certain factors by UBE2S and UBE2C plays a role in the escape from MII arrest in porcine oocytes. Further investigations to identify the factors and how mono- and/or poly-ubiquitination contributes to protein degradation could provide a better understanding of UBE2 roles in oocyte maturation. PMID- 29576590 TI - Characterization of the Axillary Microbiota of Japanese Male Subjects with Spicy and Milky Odor Types by Pyrosequencing. AB - Malodorants in the human axilla are produced from human biogenic precursors by axillary bacterial enzymes. In the present study, we used pyrosequencing analysis to identify the axillary bacterial microbiota of 13 Japanese male subjects with cumin-like, spicy body odor (C type), and 9 with milky, skin-based body odor (M type). Anaerococcus, Corynebacterium, and Staphylococcus predominated in both C- and M-type subjects, followed by Moraxella and Peptoniphilus. These genera accounted for 96.2-99.9% of the total bacterial population, except in the microbiota of one C-type subject. However, the axillary bacteria in C-type subjects were more abundant than that in M-type subjects. These results suggest that the level of colonization by axillary bacteria is important for the production of malodorants. PMID- 29576591 TI - Role of Phage Shock Protein in Recovery of Heat-injured Salmonella. AB - Sublethally heat-injured cells of Salmonella in food can recover under favorable conditions, leading to foodborne illness. To elucidate the molecular mechanism of recovery from heat injury, the global changes in gene transcription of Salmonella Typhimurium were investigated in previous study. In this study, the functions of genes involved in phage shock response (viz., phage shock protein (psp) genes), the transcription levels of which were found in previous study to be increased during recovery from heat injury, were investigated in recovering cells. The increase in pspABCDEFG transcription levels during the recovery process was confirmed by qRT-PCR. To understand the role of psp genes in heat injury recovery, a pspA deletion mutant (DeltapspA) and a pspA-overexpressing strain (S. Typhimurium pBAD30/pspA (+) ) were constructed. DeltapspA showed slightly lower viable counts and membrane potential than those of the wild-type strain during recovery. On the other hand, there was no significant difference in the viable counts between S. Typhimurium pBAD30/pspA (+) and the control strains S. Typhimurium pBAD30/pspA (-) and S. Typhimurium pBAD30 (+) during recovery. It would seem that a lack of PspA protein alone somewhat affects the recovery of S. Typhimurium from heat injury, but overexpression of PspA alone is not sufficient to overcome this effect. PMID- 29576592 TI - Comparison of Chromogenic Selective Media for the Detection of Cronobacter spp. (Enterobacter sakazakii). AB - The four types of chromogenic selective media that are commercially available in Japan were compared for establishing a Japanese standard method for detecting Cronobacter spp. based on ISO/TS 22964:2006. When assessed using 9 standard Cronobacter spp. strains and 29 non-Cronobacter strains, Enterobacter sakazakii isolation agar, ChromocultTM Enterobacter sakazakii agar, CHROMagarTM E. sakazakii, and XM-sakazakii agar demonstrated excellent inclusivity and exclusivity. Using the ISO/TS 22964:2006 method, the recovered numbers of 38 Cronobacter spp. strains, including 29 C. sakazakii isolates obtained from each medium, were equivalent, indicating that there was no significant difference (p > 0.05) among the four types of chromogenic selective media. Thus, we demonstrated that these four chromogenic selective media are suitable alternatives when using the standard method for detecting Cronobacter spp. in Japan, based on the ISO/TS 22964:2006. PMID- 29576593 TI - In vitro Inhibitory Effects of Two Bornean Medicinal Wild Gingers against Pathogenic Lagenidium thermophilum Infected Mud Crab Scylla tranquebarica. AB - The antifungal activity of two Bornean medicinal wild gingers Plagiostachys megacarpa and Zingiber phillippsiae were examined against Lagenidium thermophilum. The most active extract was P. megacarpa at concentration of 320 ug/mL inhibiting both hyphal growth and zoospore production of L. thermophilum in 24 h. Toxicity tests were conducted using mud crab (Scylla tranquebarica) larva. Bath treatment of P. megacarpa at concentrations of 320 and 640 ug/mL for 24 h were highly effective against hyphae and zoospores of the strain and it is non toxic to mud crab larva. Therefore, crude extracts P. megacarpa may be used as alternative treatment for marine Oomycete infection of mud crab. PMID- 29576594 TI - Advanced Analysis to Distinguish between Physical Decrease and Inactivation of Viable Phages in Aerosol by Quantitating Phage-Specific Particles. AB - Recent studies have investigated the efficacy of air-cleaning products against pathogens in the air. A standard method to evaluate the reduction in airborne viruses caused by an air cleaner has been established using a safe bacteriophage instead of pathogenic viruses; the reduction in airborne viruses is determined by counting the number of viable airborne phages by culture, after operating the air cleaner. The reduction in the number of viable airborne phages could be because of "physical decrease" or "inactivation". Therefore, to understand the mechanism of reduction correctly, an analysis is required to distinguish between physical decrease and inactivation. The purpose of this study was to design an analysis to distinguish between the physical decrease and inactivation of viable phi-X174 phages in aerosols. We established a suitable polymerase chain reaction (PCR) system by selecting an appropriate primer-probe set for PCR and validating the sensitivity, linearity, and specificity of the primer-probe set to robustly quantify phi-X174-specific airborne particles. Using this quantitative PCR system and culture assay, we performed a behavior analysis of the phage aerosol in a small chamber (1 m3) at different levels of humidity, as humidity is known to affect the number of viable airborne phages. The results revealed that the reduction in the number of viable airborne phages was caused not only by physical decrease but also by inactivation under particular levels of humidity. Our study could provide an advanced analysis to differentiate between the physical decrease and inactivation of viable airborne phages. PMID- 29576596 TI - Effect of Side Branch Predilation in Coronary Bifurcation Stenting With the Provisional Approach - Results From the COBIS (Coronary Bifurcation Stenting) II Registry. AB - BACKGROUND: Whether side branch (SB) predilation before main vessel (MV) stenting is beneficial is uncertain, so we investigated the effects of SB predilation on procedural and long-term outcomes in coronary bifurcation lesions treated using the provisional approach.Methods and Results:A total of 1,083 patients with true bifurcation lesions undergoing percutaneous coronary intervention were evaluated. The primary outcome was a major adverse cardiovascular event (MACE): cardiac death, myocardial infarction, or target lesion revascularization. SB predilation was performed in 437 (40.4%) patients. Abrupt (10.5% vs. 11.3%; P=0.76) or final SB occlusion (2.7% vs. 3.9%; P=0.41) showed no differences between the predilation and non-predilation groups. The rates of angiographic success (69.1% vs. 52.9%, P<0.001) and SB stent implantation (69.1% vs. 52.9%, P<0.001) were significantly higher in the predilation group. During a median follow-up of 36 months, we found no significant difference between the groups in the rate of MACE (9.4% vs. 11.5%; P=0.67) in a propensity score-matched population. In subgroup analysis, patients with minimal luminal diameter of the parent vessel <=1 mm benefited from SB predilation in terms of preventing abrupt SB occlusion (P for interaction=0.04). CONCLUSIONS: For the treatment of true bifurcation lesions, SB predilation improved acute angiographic and procedural outcomes, but could not improve long-term clinical outcomes. It may benefit patients with severe stenosis in the parent vessel. PMID- 29576595 TI - Therapeutic Efficacy of Autologous Non-Mobilized Enriched Circulating Endothelial Progenitors in Patients With Critical Limb Ischemia - The SCELTA Trial. AB - BACKGROUND: The therapeutic efficacy of bone marrow mononuclear cells (BM-MNC) autotransplantation in critical limb ischemia (CLI) has been reported. Variable proportions of circulating monocytes express low levels of CD34 (CD14+CD34lowcells) and behave in vitro as endothelial progenitor cells (EPCs). The aim of the present randomized clinical trial was to compare the safety and therapeutic effects of enriched circulating EPCs (ECEPCs) with BM-MNC administration.Methods and Results:ECEPCs (obtained from non-mobilized peripheral blood by immunomagnetic selection of CD14+and CD34+cells) or BM-MNC were injected into the gastrocnemius of the affected limb in 23 and 17 patients, respectively. After a mean of 25.2+/-18.6-month follow-up, both groups showed significant and progressive improvement in muscle perfusion (primary endpoint), rest pain, consumption of analgesics, pain-free walking distance, wound healing, quality of life, ankle-brachial index, toe-brachial index, and transcutaneous PO2. In ECEPC treated patients, there was a positive correlation between injected CD14+CD34lowcell counts and the increase in muscle perfusion. The safety profile was comparable between the ECEPC and BM-MNC treatment arms. In both groups, the number of deaths and major amputations was lower compared with eligible untreated patients and historical reference patients. CONCLUSIONS: This study supports previous trials showing the efficacy of BM-MNC autotransplantation in CLI patients and demonstrates comparable therapeutic efficacy between BM-MNC and EPEPCs. PMID- 29576597 TI - Anticoagulation Therapy for Venous Thromboembolism in the Real World - From the COMMAND VTE Registry. AB - BACKGROUND: Venous thromboembolism (VTE) has a long-term risk of recurrence, which can be prevented by anticoagulation therapy.Methods and Results:The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive patients with acute symptomatic VTE between January 2010 and August 2014. The entire cohort was divided into the transient risk (n=855, 28%), unprovoked (n=1,477, 49%), and cancer groups (n=695, 23%). The rate of anticoagulation discontinuation was highest in the cancer group (transient risk: 37.3% vs. unprovoked: 21.4% vs. cancer: 43.5% at 1 year, P<0.001). The cumulative 5-year incidences of recurrent VTE, major bleeding and all-cause death were highest in the cancer group (recurrent VTE: 7.9% vs. 9.3% vs. 17.7%, P<0.001; major bleeding: 9.0% vs. 9.4% vs. 26.6%, P<0.001; and all-cause death: 17.4% vs. 15.3% vs. 73.1%, P<0.001). After discontinuation of anticoagulation therapy, the cumulative 3-year incidence of recurrent VTE was lowest in the transient risk group (transient risk: 6.1% vs. unprovoked: 15.3% vs. cancer: 13.2%, P=0.001). The cumulative 3-year incidence of recurrent VTE beyond 1 year was lower in patients on anticoagulation than in patients off anticoagulation at 1 year in the unprovoked group (on: 3.7% vs. off: 12.2%, P<0.001), but not in the transient risk and cancer groups (respectively, 1.6% vs. 2.5%, P=0.30; 5.6% vs. 8.6%, P=0.44). CONCLUSIONS: The duration of anticoagulation therapy varied widely in discordance with current guideline recommendations. Optimal duration of anticoagulation therapy should be defined according to the risk of recurrent VTE and bleeding as well as death. PMID- 29576598 TI - Clinical Characteristics, Management, and Outcomes of Japanese Patients Hospitalized for Heart Failure With Preserved Ejection Fraction - A Report From the Japanese Heart Failure Syndrome With Preserved Ejection Fraction (JASPER) Registry. AB - BACKGROUND: Despite the specific characteristics of heart failure with preserved ejection fraction (HFpEF) having been demonstrated predominantly from registries in Western countries, important international differences exist in terms of patient characteristics, management and medical infrastructure between Western and Asian countries.Methods and Results:We performed nationwide registration of consecutive Japanese hospitalized HFpEF patients with left ventricular EF >=50% from 15 sites between November 2012 and March 2015. Follow-up data were obtained up to 2 years post-discharge. A total of 535 patients were registered. The median age was 80 years and 50% were female. The most common comorbid conditions were hypertension (77%) and atrial fibrillation (AF: 62%), but body mass index was relatively low. In-hospital mortality rate was 1.3% and the median length of hospitalization was 16 days. By 2 years post-discharge, 40.8% of patients had all cause death or HF hospitalization. Approximately one-half of deaths had a cardiac cause. Lower serum albumin on admission was one of the strongest independent determinants of worse clinical outcome. CONCLUSIONS: Japanese HFpEF patients were less obese, but had a substantially higher prevalence of AF and lower incidence of subsequent events compared with previous reports. Our findings indicated that specific preventative and therapeutic strategies focusing on AF and nutritional status might need to be considered for Japanese hospitalized patients with HFpEF. PMID- 29576599 TI - New diagnostic criteria of adrenal subclinical Cushing's syndrome: opinion from the Japan Endocrine Society. AB - New diagnostic criteria and the treatment policy for adrenal subclinical Cushing's syndrome (SCS) are proposed on behalf of the Japan Endocrine Society. The Japanese version has been published, and the essential contents are presented in this English-language version. The current diagnostic criteria for SCS have elicited two main problems: (i) the relatively low reliability of a low range of serum cortisol essential for the diagnosis by an overnight 1-mg dexamethasone suppression test (DST); (ii) different cutoff values for serum cortisol after a 1 mg DST compared with those of other countries. Thus, new criteria are needed. In the new criteria, three hierarchical cortisol cutoff values, 5.0, 3.0 and 1.8 MUg/dL, after a 1-mg DST are presented. Serum cortisol >=5 MUg/dL after a 1-mg DST alone is considered sufficient to judge autonomous cortisol secretion for the diagnosis of SCS, and the current criterion based on serum cortisol >=3 MUg/dL after a 1-mg DST can continue to be used. Clinical evidence suggests that serum cortisol >=1.8-2.9 MUg/dL after a 1-mg DST is not always normal, so cases who meet the cutoff value as well as a basal adrenocorticotropic hormone (ACTH) level <10 pg/mL (or poor ACTH response to corticotropin-releasing hormone (CRH)) and nocturnal serum cortisol >=5 MUg/dL are proposed to have SCS. We suggest surgery if cases show serum cortisol >=5 MUg/dL after a 1-mg DST (or are disheartened by treatment-resistant problems) or suspicious cases of adrenal cancer according to tumor imaging. PMID- 29576600 TI - Tumor necrosis factor alpha improves glucose homeostasis in diabetic mice independent with tumor necrosis factor receptor 1 and tumor necrosis factor receptor 2. AB - Type 2 diabetes is a serious threat to human health all over the world. It is particularly important to look for the pathogenesis of type 2 diabetes. Researchers have found that obesity was associated with a broad chronic inflammatory response and type 2 diabetes. And tumor necrosis factor alpha (TNF alpha) is one of the most important cytokines related with obesity. To explore the functional role of TNF-alpha in the regulation of glucose homeostasis, TNF alpha receptor 1 and TNF-alpha receptor 2 double knockout (TNFR1/R2 DKO) mouse model were used in our study. After high fat diet (HFD) feeding, we detected that the insulin resistance was dramatically improved and circulated TNF-alpha was upregulated in TNFR1/R2 DKO mice. Surprisingly, glucose homeostasis was worsened, when we down regulate the levels of plasma TNF-alpha in TNFR1/R2 DKO mice by administering Adeno associated virus-shRNA-TNF-alpha (AAV-shTNF-alpha). Subsequently, in ob/ob mice, we confirmed that the glucose homeostasis could be improved when we up regulate the levels of plasma TNF-alpha by administering Adeno associated virus-TNF-alpha (AAV-TNF-alpha). Our findings suggested that TNFR1 and TNFR2 may not be the only receptors for TNF-alpha and TNF-alpha probably plays a positive role in reducing insulin resistance via a TNFRs independent way in diabetic mice. PMID- 29576601 TI - Genome Database of the Latvian Population (LGDB): Design, Goals, and Primary Results. AB - BACKGROUND: The Genome Database of the Latvian Population (LGDB) is a national biobank that collects, maintains, and processes health information, data, and biospecimens collected from representatives of the Latvian population. These specimens serve as a foundation for epidemiological research and prophylactic and therapeutic purposes. METHODS: Participant recruitment and biomaterial and data processing were performed according to specifically designed standard protocols, taking into consideration international quality requirements. Legal and ethical aspects, including broad informed consent and personal data protection, were applied according to legal norms of the Republic of Latvia. RESULTS: Since its start in 2006, the LGDB is comprised of biosamples and associated phenotypic and clinical information from over 31,504 participants, constituting approximately 1.5% of the Latvian population. The LGDB represents a mixed-design biobank and includes participants from the general population as well as disease-based cohorts. The standard set of biosamples stored in the LGDB consists of DNA, plasma, serum, and white blood cells; in some cohorts, these samples are complemented by cancer biopsies and microbiome and urine samples. The LGDB acts as a core structure for the Latvian Biomedical Research and Study Centre (BMC), representing the national node of Latvia in Biobanking and BioMolecular resources Research Infrastructure - European Research Infrastructure Consortium (BBMRI ERIC). CONCLUSIONS: The development of the LGDB has enabled resources for biomedical research and promoted genetic testing in Latvia. Further challenges of the LGDB are the enrichment and harmonization of collected biosamples and data, the follow-up of selected participant groups, and continued networking and participation in collaboration projects. PMID- 29576603 TI - Socioeconomic Inequalities in Oral Health Among Unmarried and Married Women: Evidence From a Population-Based Study in Japan. AB - BACKGROUND: Socioeconomic inequalities in oral health have been reported in developed countries, but the influence of marital status has rarely been considered. Our aim was to examine marital status differentials in the association between socioeconomic status (SES) and oral health among community dwelling Japanese women. METHODS: From 2010 to 2011, a questionnaire survey was conducted among residents aged 25-50 years in Japanese metropolitan areas. Valid responses were received from 626 unmarried women and 1,620 married women. Women's own and husbands' educational attainment and equivalent income were used to assess SES. Self-rated "fair" or "poor" oral health was defined as poor oral health. Multiple logistic regression analysis was conducted to examine which SES indicators were associated with oral health. RESULTS: The prevalence of poor oral health was 21.1% among unmarried women and 23.8% among married women. Among unmarried women, equivalent income was not associated with oral health, but women's own education was significantly associated with oral health; the multivariate-adjusted odds ratio of poor oral health among those with high school education or lower compared to those with university education or higher was 2.14 (95% confidence interval, 1.19-3.87). Among married women, neither women's own nor husbands' education was associated with oral health, but equivalent income was significantly associated with oral health, particularly among housewives; the multivariate-adjusted odds ratio of poor oral health among those in the lowest compared with highest income quartile was 1.57 (95% confidence interval, 1.08 2.27). CONCLUSIONS: These findings indicate that marital status should be considered when examining associations between SES and oral health among Japanese women. PMID- 29576604 TI - Parental Internet Use and Lifestyle Factors as Correlates of Prolonged Screen Time of Children in Japan: Results From the Super Shokuiku School Project. AB - BACKGROUND: Prolonged screen time (ST), which includes TV viewing and gaming on smartphones and computers, is linked to poor health. Our aim was to explore the associations between school children with prolonged ST and parental internet use (IU) and lifestyles in Japan. METHODS: Children aged 6 to 13 years from the Super Shokuiku School Project, were surveyed using questionnaires in 2016. The survey assessed the grade, sex, and lifestyle of 1,659 children and parental internet use (IU) and lifestyle using Breslow's seven health behaviors. IU consisted of internet surfing and gaming on personal computers (PC), smartphones, or consoles. Three or more hours of ST was defined as prolonged ST, and its correlates were analyzed using logistic regression. RESULTS: Of all, 643 (38.8%) children spent >=2 hours/day of ST on a week day, whilst 153 (9.2%) children spent >=3 hours/day. Prolonged ST was significantly associated with children in higher grade (odds ratio [OR] 1.74; 95% confidence interval [CI], 1.20-2.51), boys (OR 2.16; 95% CI, 1.49-3.14), skipping breakfast (OR 1.88; 95% CI, 1.05-3.35), late bedtime (OR 1.80; 95% CI, 1.15-2.82), physical inactivity (OR 1.79; 95% CI, 1.12 2.87), father's IU >=2 hours/day (OR 2.35; 95% CI, 1.52-3.63), mother's prolonged IU >=2 hours/day (OR 2.55; 95% CI, 1.43-4.52), mothers with unhealthy behaviors (OR 1.81; 95% CI, 1.05-3.13), no rule setting governing screen time (OR 2.41; 95% CI, 1.63-3.58), and mothers with full-time employment (OR 1.95; 95% CI, 1.06 3.64). CONCLUSIONS: Prolonged ST among Japanese children was strongly associated with parental IU, no set rules for ST, and mother's unhealthy lifestyles. To reduce children's ST, parental engagement is warranted in the intervention strategy. PMID- 29576602 TI - Association of Adiponectin With Cancer and All-Cause Mortality in a Japanese Community-Dwelling Elderly Cohort: A Case-Cohort Study. AB - BACKGROUND: Most studies of plasma adiponectin (APN) and mortality among community-dwelling elderly focus on cardiovascular disease, but data on the relationship between plasma APN and cancer mortality is exiguous. We investigated whether APN is associated with cancer mortality in community-dwelling elderly people. METHODS: We conducted a case-cohort study within the New Integrated Suburban Seniority Investigation (NISSIN) Project using a randomly drawn sub cohort of 697 subjects (351 men and 346 women; mean age 64.5 [standard deviation, 0.5] years) among whom we compared cases of all-cause death (n = 269) and cancer death (n = 149) during a mean follow-up duration of 10.8 (standard deviation, 3.7) years. Associations between APN and mortality were assessed using weighted Cox regression analyses. RESULTS: We observed significant positive associations between the APN concentration and cancer death in the first and third APN tertiles compared with the second APN tertile (hazard ratio [HR]T1 vs T2, 1.67; 95% confidence interval [CI], 1.00-2.79 and HRT3 vs T2, 2.10; 95% CI, 1.30-3.40). Further adjustment for possible confounders attenuated the association (HRT1 vs T2, 1.63; 95% CI, 0.93-2.84 and HRT3 vs T2, 2.10; 95% CI, 1.26-3.50). A similar but weaker association was seen for all-cause mortality (multivariate HRT1 vs T2, 1.45; 95% CI, 0.95-2.21 and HRT3 vs T2, 1.51; 95% CI, 1.01-2.25). CONCLUSION: Plasma APN and cancer mortality have a significant relationship among community dwelling elderly people, which warrants further study. PMID- 29576605 TI - MAP Kinase-Interacting Kinase 1 Promotes Proliferation and Invasion of Hepatocellular Carcinoma and Is an Unfavorable Prognostic Biomarker. AB - BACKGROUND Hepatocellular carcinoma (HCC) accounts for one of the most prevalent tumor types in the world. The MAP kinase-interacting kinase 1 (MNK1) functions downstream of MAP kinases such as p38 and ERK, and its potential role in cancer development is being uncovered. The aim of this study was to investigate the expression and function of MNK1 in HCC. MATERIAL AND METHODS Immunohistochemical staining and quantitative PCR were performed to explore the expression of MNK1 in both HCC tissues and adjacent normal liver tissues. Chi-square test, univariate analysis, and multivariate analysis were conducted to statistically evaluate clinical significance of MNK1 in HCC. Proliferation, migration, and invasion capacities of HCC cells were assessed after overexpressing or silencing MNK1. RESULTS Both the RNA and protein levels of MNK1 were upregulated in HCC tissues compared to normal liver tissues. High expression of MNK1 was correlated with advanced tumor stage and poor overall survival. Moreover, MNK1 was identified as a novel independent prognostic factor for HCC patients. Cellular studies showed that MNK1 can enhance the proliferation, migration, and invasion capacities of HCC cells, thereby promoting tumor progression. CONCLUSIONS High expression of MNK1 is frequent in HCC tissues, which promotes tumor proliferation and invasion, and is correlated with a poor overall survival. Targeting MNK1 may be a novel direction for the drug development of HCC therapy. PMID- 29576606 TI - Gastric Metastasis as the First Presentation One Year Before Diagnosis of Primary Breast Cancer. AB - BACKGROUND Metastasis to the stomach can be found as the first presentation of breast cancer, although it is very rare. The authors report an unusual case of metastasis to the stomach as the first presentation of breast cancer, which had a good prognosis. CASE REPORT A 51-year-old female underwent radical subtotal gastrectomy and chemotherapy because of gastric cancer with distant metastasis. At the time of diagnosis of gastric cancer, she had a negative result from routine mammography. One year later, a newly detected lesion on routine mammography was confirmed as breast cancer. Initial diagnosis of gastric cancer was changed to metastatic carcinoma from breast cancer through immunohistochemistry after bilateral mastectomy. After the completion of chemotherapy, she is currently receiving treatment with letrozole, without recurrence for 66 months. CONCLUSIONS Considering metastasis from breast cancer might be needed when unusual presentation of gastric cancer is observed even though gastric cancer is still one of the most common malignancies in Korea. Immunohistochemical analysis is helpful for diagnosis. Surgery for metastatic carcinoma of the stomach could be another option for treatment.

PMID- 29576608 TI - Evaluating major curriculum change: the effect on student confidence. PMID- 29576609 TI - Initiating research in a private dental practice. AB - Research is an intrinsic part of both academia and clinical best practice. Within an academic environment, this can include access to advice and guidance from trained professionals. Similarly, while sometimes overly risk-averse, within the NHS there is a structured and systematic approach to healthcare research. However, in the UK, a large number of specialist dental procedures take place within the private healthcare system, which does not have access to such support and guidance. How, then, can we generate our own dental research from private dental primary care settings? With a number of phrases becoming part of everyday vocabulary in dental primary care, such as practice-based research, patient centred outcomes, evidence-based dentistry, it is time to consider this. From research ethics to writing papers, via GCP, IRAS, HEIs and MOOCs, this article summarises the experiences of one non-affiliated (non-academic, non-NHS) private dental practice attempting to enter the world of research. The authors discuss their experiences, share the multiple sources of support encountered along the way, and demonstrate the benefits to everyday practice gained by initiating research studies.

PMID- 29576612 TI - Protein kinase A-mediated phosphorylation regulates STAT3 activation and oncogenic EZH2 activity. AB - Polycomb repressive complex 2 (PRC2) member enhancer of zeste homolog 2 (EZH2) trimethylates histone H3 lysine 27 (H3K27me3), alters chromatin structure and contributes to epigenetic regulation of gene expression in normal and disease processes. Phosphorylation of EZH2 augmented EZH2 oncogenic activity in cancer but observations have been limited to threonine 350 (T350) and serine 21 (S21) residues by cyclin-dependent kinase 1 and protein kinase B, respectively. In addition, phosphorylation of the evolutionarily conserved T372 motif of EZH2 by p38 resulted in EZH2 interaction with Ying Yang 1 and promoted muscle stem cell differentiation. In the present study, we used epithelial ovarian cancer (OC) cells as a model to demonstrate that phosphorylation of EZH2 at T372 by protein kinase A (PKA) induced a dominant-negative EZH2 phenotype, inhibited OC cell proliferation and migration in vitro and decreased ovarian xenograft tumor growth in vivo. Phosphorylation of T372 by PKA enhanced the interaction between EZH2 and signal transducer and activator of transcription 3 (STAT3), and STAT3 binding to pT372-EZH2 reduced cellular levels of pSTAT3 and downregulated interleukin 6 receptor expression in OC. Furthermore, PKA-mediated pT372-EZH2 decreased ATP levels and altered mitochondrial gene expression, resulting in mitochondrial dysfunction and reduced OC cell growth. These findings demonstrate that PKA mediated T372 phosphorylation reduces oncogenic EZH2 activity and reveal a novel role for pT372 in regulating EZH2 in OC and possibly other cancers. PMID- 29576613 TI - HOXB7 overexpression in lung cancer is a hallmark of acquired stem-like phenotype. AB - HOXB7 is a homeodomain (HOX) transcription factor involved in regional body patterning of invertebrates and vertebrates. We previously identified HOXB7 within a ten-gene prognostic signature for lung adenocarcinoma, where increased expression of HOXB7 was associated with poor prognosis. This raises the question of how HOXB7 overexpression can influence the metastatic behavior of lung adenocarcinoma. Here, we analyzed publicly available microarray and RNA-seq lung cancer expression datasets and found that HOXB7-overexpressing tumors are enriched in gene signatures characterizing adult and embryonic stem cells (SC), and induced pluripotent stem cells (iPSC). Experimentally, we found that HOXB7 upregulates several canonical SC/iPSC markers and sustains the expansion of a subpopulation of cells with SC characteristics, through modulation of LIN28B, an emerging cancer gene and pluripotency factor, which we discovered to be a direct target of HOXB7. We validated this new circuit by showing that HOXB7 enhances reprogramming to iPSC with comparable efficiency to LIN28B or its target c-MYC, which is a canonical reprogramming factor.

AB - Mutations, the fuel of evolution, are first manifested as rare DNA changes within a population of cells. Although next-generation sequencing (NGS) technologies have revolutionized the study of genomic variation between species and individual organisms, most have limited ability to accurately detect and quantify rare variants among the different genome copies in heterogeneous mixtures of cells or molecules. We describe the technical challenges in characterizing subclonal variants using conventional NGS protocols and the recent development of error correction strategies, both computational and experimental, including consensus sequencing of single DNA molecules. We also highlight major applications for low frequency mutation detection in science and medicine, describe emerging methodologies and provide our vision for the future of DNA sequencing. PMID- 29576617 TI - What do we know about the macular pigment in AMD: the past, the present, and the future. AB - Carotenoids are lipophilic isoprenoid pigments with a common C40H56 core chemical structure that are naturally synthesized by many plants, algae, bacteria, and fungi. Humans and animals cannot synthesize carotenoids de novo and must obtain them solely through dietary sources. Among the more than 750 carotenoids in nature, only lutein, zeaxanthin, meso-zeaxanthin, and their oxidative metabolites selectively accumulate in the foveal region of the retina where they are collectively referred to as the macular pigment (MP) of the macula lutea. MP serves an ocular protective role through its ability to filter phototoxic blue light radiation and also via its antioxidant activity. These properties have led to the hypothesis that carotenoids may protect against the development of age related macular degeneration (AMD), the most common cause of blindness in the aged population >60 years old. Epidemiological studies have supported this by showing that patients with lower concentrations of serum carotenoids and macular pigment optical density (MPOD) measurements are at a higher risk of developing AMD. Conversely, nutritional supplementation and diets rich in lutein and zeaxanthin readily impact MP concentrations and reduce the risk of progression to advanced AMD, and the AREDS2 supplement formulation containing 10 mg of lutein and 2 mg of zeaxanthin is the standard-of-care recommendation for individuals at risk for visual loss from advanced AMD. This article reviews the rich history of research on the MP dating back to the 1700s and outlines their potential for further therapeutic improvements for AMD in the future.

AB - PURPOSE: Keratoconus (KC) is a multifactorial, ectatic corneal disease. Metabolic changes in the corneal stroma with alterations in collagen fibril stability, oxidative stress, and urea cycle, have previously been reported as key players in KC pathobiology. Recently, corneal collagen cross-linking (CXL) has been introduced as a treatment that can address the progressive nature of KC. While the treatment has been successful in the early days, it is not without clinical ramifications. In this study, we investigated the alterations in KC metabolic profiles due to CXL. METHODS: Primary human corneal fibroblasts (HCFs) from healthy donors and human KC fibroblasts (HKCs) from KC donor patients were plated on transwell polycarbonate membranes and stimulated by a stable vitamin C. At 4 weeks, riboflavin was added to the cultures followed by UVA irradiation (365 nm). Using mass spectrometry, we measured the major differences in metabolites in HKCs compared to HCFs pre- and post CXL. RESULT: The analysis of 276 metabolites in HCFs and HKCs revealed that the most affected metabolites due to CXL were glutathione disulfide, ascorbic acid, proline, and lysine. A significant decrease in the pro-inflammatory biomarkers (myo-inositol and histidine) was also observed. Furthermore, a significant downregulation of many amino acids, lactate levels, and other water-soluble metabolites was noted in HKCs following CXL. CONCLUSION: CXL is a KC treatment available to patients within certain criteria. Surprisingly, the cellular and molecular mechanisms are considerably understudied limiting our ability for more precise and targeted CXL treatments. In this study, for the first time, we report the effects of CXL on KC metabolism. PMID- 29576620 TI - Marine microbiology: Carbon export into the deep ocean. PMID- 29576621 TI - The mechanism study of lentiviral vector carrying methioninase enhances the sensitivity of drug-resistant gastric cancer cells to Cisplatin. AB - BACKGROUND: To investigate the mechanism of lentiviral vector carrying methioninase enhances the sensitivity of drug-resistant gastric cancer cells to Cisplatin. METHODS: Death receptors, anti-apoptotic protein, NF-kappaB, and TRAIL pathway-related factors were detected. The influence of LV-METase transfection on cell viability and pathway-related proteins were assessed by MTT method and western blot, respectively. Different treatments (NF-kappaB or caspase-3 inhibitor induction, TRAIL supplement, etc.) were performed in gastric cancer cells and the above parameters were analysed. Moreover, the connection between miR-21 and NF-kappaB or caspase-8 was determined by Chip and luciferase assay, respectively. LV-METase transfection drug-resistant gastric cancer cells were injected subcutaneously into mice. RESULTS: The expression of free MET, miR-21 5p, MDR1, P-gp, and DR5 was significantly increased in drug-resistant gastric cancer cell lines. When cells were transfected with LV-METase, intracellular TRAIL signalling was activated while NF-kappaB pathway was inhibited. Besides, enhanced TRAIL signalling or repressed NF-kappaB pathway can promote the sensitivity of drug-resistant strains to Cisplatin, and the combination shows more sensitive to sensitisation. LV-METase promoted TRAIL expression by reducing NF-kappaB, thereby contributing to the downregulation of P-gp and enhancing the susceptibility of drug-resistant gastric cancer cells to Cisplatin. Furthermore, miR-21 regulated by NF-kappaB mediated the expression of P-gp protein via inhibiting caspase-8, thus regulating Cisplatin-induced cell death. CONCLUSIONS: Our results suggest that LV-METase has potential as a therapeutic agent for gastric cancer treatment. PMID- 29576622 TI - Predicting cumulative incidence of adverse events in older patients with cancer undergoing first-line palliative chemotherapy: Korean Cancer Study Group (KCSG) multicentre prospective study. AB - BACKGROUND: Older patients have increased risk of toxicity from chemotherapy. Current prediction tools do not provide information on cumulative risk. METHODS: Patients aged >= 70 years with solid cancer were prospectively enrolled. A prediction model was developed for adverse events (AEs) >= Grade 3 (G3), based on geriatric assessment (GA), laboratory, and clinical variables. RESULTS: 301 patients were enrolled (median age, 75 years). Median number of chemotherapy cycles was 4. During first-line chemotherapy, 53.8% of patients experienced AEs >= G3. Serum protein < 6.7 g/dL, initial full-dose chemotherapy, psychological stress or acute disease in the past 3 months, water consumption < 3 cups/day, unable to obey a simple command, and self-perception of poor health were significantly related with AEs >= G3. A predicting model with these six variables ranging 0-8 points was selected with the highest discriminatory ability (c statistic= 0.646), which could classify patients into four risk groups. Predicted cumulative incidence of AEs >= G3 was discriminated according to risk groups. CONCLUSIONS: This prediction tool could identify the risk of AEs >= G3 after chemotherapy and provide information on the cumulative incidence of AEs in each cycle. CLINICAL TRIAL ID: WHO ICTRP number, KCT0001071. PMID- 29576623 TI - Optoacoustics delineates murine breast cancer models displaying angiogenesis and vascular mimicry. AB - BACKGROUND: Optoacoustic tomography (OT) of breast tumour oxygenation is a promising new technique, currently in clinical trials, which may help to determine disease stage and therapeutic response. However, the ability of OT to distinguish breast tumours displaying different vascular characteristics has yet to be established. The aim of the study is to prove OT as a sensitive technique for differentiating breast tumour models with manifestly different vasculatures. METHODS: Multispectral OT (MSOT) was performed in oestrogen-dependent (MCF-7) and oestrogen-independent (MDA-MB-231) orthotopic breast cancer xenografts. Total haemoglobin (THb) and oxygen saturation (SO2MSOT) were calculated. Pathological and biochemical evaluation of the tumour vascular phenotype was performed for validation. RESULTS: MCF-7 tumours show SO2MSOT similar to healthy tissue in both rim and core, despite significantly lower THb in the core. MDA-MB-231 tumours show markedly lower SO2MSOT with a significant rim-core disparity. Ex vivo analysis revealed that MCF-7 tumours contain fewer blood vessels (CD31+) that are more mature (CD31+/aSMA+) than MDA-MB-231. MCF-7 presented higher levels of stromal VEGF and iNOS, with increased NO serum levels. The vasculogenic process observed in MCF-7 was consistent with angiogenesis, while MDA-MB-231 appeared to rely more on vascular mimicry. CONCLUSIONS: OT is sensitive to differences in the vascular phenotypes of our breast cancer models. PMID- 29576624 TI - Long-term follow-up of overall survival for cabozantinib versus everolimus in advanced renal cell carcinoma. AB - BACKGROUND: In the phase 3 METEOR trial (NCT01865747), cabozantinib significantly improved progression-free survival, overall survival, and objective response rate compared with everolimus in patients with advanced renal cell carcinoma (RCC) after prior antiangiogenic therapy. A statistically significant improvement in overall survival was observed at a second interim analysis with 320 recorded deaths. METHODS: 658 patients with advanced RCC who had received at least one prior VEGFR tyrosine kinase inhibitor were randomised 1:1 to cabozantinib (60 mg daily) or everolimus (10 mg daily). Survival follow-up continued to reach the 408 deaths that were pre-specified for the final analysis. RESULTS: With 430 deaths (198 for cabozantinib and 232 for everolimus), median overall survival was 21.4 months with cabozantinib and 17.1 months with everolimus (HR 0.70, 95% CI 0.58 0.85; P = 0.0002). Safety profiles of cabozantinib and everolimus were consistent with those reported previously. CONCLUSIONS: Cabozantinib significantly improved overall survival compared with everolimus in previously treated patients with advanced RCC with consistent results after long-term follow-up. PMID- 29576626 TI - A message for 2018. PMID- 29576625 TI - Targeting glutaminolysis in chondrosarcoma in context of the IDH1/2 mutation. AB - INTRODUCTION: Chondrosarcoma is a malignant cartilage-forming bone tumour in which mutations in IDH1 and IDH2 frequently occur. Previous studies suggest an increased dependency on glutaminolysis in IDH1/2 mutant cells, which resulted in clinical trials with the drugs CB-839, metformin and chloroquine. In this study, the preclinical rationale for using these drugs as a treatment for chondrosarcoma was evaluated. METHODS: Expression of glutaminase was determined in 120 cartilage tumours by immunohistochemistry. Ten chondrosarcoma cell lines were treated with the metabolic compounds CB-849, metformin, phenformin (lipophilic analogue of metformin) and chloroquine. RESULTS: A difference in glutaminase expression levels between the different tumour grades (p = 0.001, one-way ANOVA) was identified, with the highest expression observed in high-grade chondrosarcomas. Treatment with CB-839, metformin, phenformin or chloroquine revealed that chondrosarcoma cell lines are sensitive to glutaminolysis inhibition. Metformin and phenformin decreased mTOR activity in chondrosarcoma cells, and metformin decreased LC3B-II levels, which is counteracted by chloroquine. CONCLUSION: Targeting glutaminolysis with CB-839, metformin, phenformin or chloroquine is a potential therapeutic strategy for a subset of high-grade chondrosarcomas, irrespective of the presence or absence of an IDH1/2 mutation.

PMID- 29576628 TI - Photoacoustic technique to measure temperature effects on microbubble viscoelastic properties. AB - Phospholipid-coated microbubbles are being developed for several biomedical applications, but little is known about the effect of temperature on the viscoelastic properties of the shell. Here, we report on the use of a photoacoustic technique to study the shell properties of individual microbubbles as a function of temperature. The microbubbles were driven into small-amplitude oscillations by ultrasound waves generated from the absorption of an intensity modulated infrared laser, and these oscillations were detected by forward-light scattering of a second blue laser. The drive laser modulation frequency was swept to determine the resonant response of 2-4 MUm radius microbubbles. Lipid shell elasticity and viscosity were determined by modeling the microbubble response as a linear harmonic oscillator. The results from slow heating showed a linear decrease in elasticity and viscosity between 21 and 53 degrees C and a corresponding increase in the maximum oscillation amplitude. Rapid heating to 38 degrees C, on the other hand, showed a transient response in the viscoelastic properties, suggesting shell rupture and reformation during microbubble growth and subsequent dissolution. These effects are important for biomedical applications, which require warming of the microbubbles to body temperature.

AB - This summary provides an overview of how new therapies or new aspects of established therapies relate to the latest findings. Neoadjuvant therapy, local therapy, new aspects of systemic therapy, and prognostic and predictive factors are presented. In the neoadjuvant setting, the association between pathological complete response (pCR) and prognosis is still of interest as is the identification of new molecular predictors for new therapies such as CDK4/6 inhibitors. As regards surgical treatment, the target is still to reduce the aggressiveness of surgery. To achieve this, a better understanding particularly of ductal carcinoma in situ is required. With regard to systemic therapy, more data on the best combinations and therapy sequences for existing therapies is available. Finally, the use of prognostic and predictive factors may help to avoid overtreatment and ensure that patients only receive therapies which have been shown to be effective for their specific condition and have fewer side effects. PMID- 29576630 TI - Update Breast Cancer 2018 (Part 2) - Advanced Breast Cancer, Quality of Life and Prevention. AB - The treatment of metastatic breast cancer has become more complicated due to increasing numbers of new therapies which need to be tested. Therapies are now being developed to treat special clinical or molecular subgroups. Even though intrinsic molecular subtypes play a major role, more and more new therapies for subgroups and histological subtypes are being developed, such as the use of PARP inhibitors to treat patients with BRCA mutations (breast and ovarian cancer). Supportive therapies are also evolving, allowing problems such as alopecia or nausea and vomiting to be treated more effectively. Treatment-related side effects have a direct impact on the prognosis of patients with metastatic breast cancer, and supportive therapy can improve compliance. Digital tools could be useful to establish better patient management systems. This overview provides an insight into recent trials and how the findings could affect routine treatment. Current aspects of breast cancer prevention are also presented. PMID- 29576631 TI - Active Immunisation with Partner Lymphocytes in Female Patients Who Want to Become Pregnant - Current Status. AB - Around 1 - 3% of all couples who try to have a child are affected by recurrent miscarriage. According to the WHO, recurrent miscarriage is defined as the occurrence of three or more consecutive miscarriages up to the 20th week of pregnancy. There are various causes of recurrent miscarriage; in many cases, the causes remain unclear, with the result that immunological factors are one of the possible causes discussed. For the mother's immune system, the embryo represents a semi-allogeneic transplant, as half of the embryo's genes are of paternal origin. In place of a conventional immune response, the embryo induces a secondary protection mechanism, which contributes to the successful implantation. When performing immunisation with partner lymphocytes, the patient receives an intradermal injection of her partner's prepared lymphocytes into the volar side of the forearm in order to induce immunomodulation with a consequently increased rate of pregnancy and live birth. A prerequisite for this procedure is that all other possible causes of sterility have been ruled out in advance. Due to the highly heterogeneous nature of the data, a significant benefit as a result of the immunisation cannot yet be clearly proven. However, there are signs that the therapy may be effective when using lymphocytes that have been extracted as short a time beforehand as possible. Overall, the treatment represents a safe, low-risk procedure. Following a detailed informative discussion with the couple regarding the chances of success and following a detailed review of the indication and contraindications, immunisation with partner lymphocytes can be discussed with the couple on a case-by-case basis - provided that all other possible causes of sterility have been ruled out in advance.

PMID- 29576632 TI - Maternal Thrombophilia and Recurrent Miscarriage - Is There Evidence That Heparin is Indicated as Prophylaxis against Recurrence? AB - Background: Recurrent miscarriage, also referred to as recurrent spontaneous abortion (RSA), affects 1 - 5% of couples and has a multifactorial genesis. Acquired and congenital thrombophilia have been discussed as hemostatic risk factors in the pathogenesis of RSA. Method: This review article was based on a selective search of the literature in PubMed. There was a special focus on the current body of evidence studying the association between RSA and antiphospholipid syndrome and hereditary thrombophilia disorders. Results: Antiphospholipid syndrome (APS) is an acquired autoimmune thrombophilia and recurrent miscarriage is one of its clinical classification criteria. The presence of lupus anticoagulant has been shown to be the most important serologic risk factor for developing complications of pregnancy. A combination of low-dose acetylsalicylic acid and heparin has shown significant benefits with regard to pregnancy outcomes and APS-related miscarriage. Some congenital thrombophilic disorders also have an increased associated risk of developing RSA, although the risk is lower than for APS. The current analysis does not sufficiently support the analogous administration of heparin as prophylaxis against miscarriage in women with congenital thrombophilia in the same way as it is used in antiphospholipid syndrome. The data on rare, combined or homozygous thrombophilias and their impact on RSA are still insufficient. Conclusion: In contrast to antiphospholipid syndrome, the current data from studies on recurrent spontaneous abortion do not support the prophylactic administration of heparin to treat women with maternal hereditary thrombophilia in subsequent pregnancies. Nevertheless, the maternal risk of thromboembolic events must determine the indication for thrombosis prophylaxis in pregnancy. PMID- 29576634 TI - Psst, Can You Keep a Secret?

PMID- 29576636 TI - Drug-resistant Spinal Tuberculosis. AB - Drug-resistant spinal tuberculosis (TB) is an emerging health problem in both developing and developed countries. In this review article, we aim to define management protocols for suspicion, diagnosis, and treatment of such patients. Spinal TB is a deep-seated paucibacillary lesion, and the demonstration of acid fast bacilli on Ziehl-Neelsen staining is possible only in 10%-30% of cases. Drug resistance is suspected in patients showing the failure of clinicoradiological improvement or appearance of a fresh lesion of osteoarticular TB while on anti tubercular therapy (ATT) for a minimum period of 5 months. The conventional culture of Mycobacterium tuberculosis remains the gold standard for both bacteriological diagnosis and drug sensitivity testing (DST); however, the high turn around time of 2-6 weeks for detection with added 3 weeks for DST is a major limitation. To overcome this problem, rapid culture methods and molecular methods have been introduced. From a public health perspective, reducing the period between diagnosis and treatment initiation has direct benefits for both the patient and the community. For all patients of drug-resistant spinal TB, a complete Drug-O-Gram should be prepared which includes details of all drugs, their doses, and duration. Patients with confirmed multidrug-resistant TB strains should receive a regimen with at least five effective drugs, including pyrazinamide and one injectable. Patients with resistance to additional antitubercular drugs should receive individualized ATT as per their DST results. PMID- 29576637 TI - Complications Associated with Locking Plate of Proximal Humerus Fractures. AB - Proximal humerus fractures constitute a significant percentage of fragility fractures. The growing use of locking plate has helped treat this problem, but at the same time has brought about complications. Past systematic reviews have documented these complications, however a large number of recent studies have been published since, reporting their own complication rates with different techniques. This study reviews the current complications associated with locking plate of proximal humerus fractures as well as methods to reduce them. A systematic review, following the PRISMA guidelines, was conducted in November 2013 and repeated in March 2015, using PubMed, Scopus, and Cochrane databases, to evaluate locking plate fixation (and complications) of traumatic proximal humerus fractures. Inclusion criteria included adults (>18 years), minimum of 12-month postoperative followup, articles within the last 5 years, and studies with >10 participants. Exclusion criteria included pathologic fractures, cadaveric studies, and nonhuman subjects. Eligible studies were graded using a quality scoring system. Articles with a minimum of 7/10 score were included and assessed regarding their level of evidence per the Journal of Bone and Joint Surgery and Centre for Evidence-Based Medicine guidelines. The initial query identified 51,206 articles from multiple databases. These records were thoroughly screened and resulted in 57 articles, consisting of seven Level 1, three Level 2, 10 Level 3, and 37 Level 4 studies, totaling 3422 proximal humerus fractures treated with locking plates. Intraarticular screw penetration was the most reported complication (9.5%), followed by varus collapse (6.8%), subacromial impingement (5.0%), avascular necrosis (4.6%), adhesive capsulitis (4.0%), nonunion (1.5%), and deep infection (1.4%). Reoperation occurred at a rate of 13.8%. Collapse at the fracture site contributed to a majority of the implant-related complications, which in turn were the main reasons for reoperation. The authors of these studies discussed different techniques that could be used to address these issues. Expanding use of locking plate in the proximal humerus fractures leads to improvements and advancements in surgical technique. Further research is necessary to outline indications to decrease complications, further. PMID- 29576638 TI - Is Combined Administration of Tranexamic Acid Better than Both Intravenous and Topical Regimes for Total Loss, Hidden Loss and Post-operative Swelling? A Randomized Control Trial. AB - Background: Bleeding is one of the unavoidable complications of total knee arthroplasty (TKA). Tranexamic acid (TXA) in last decade has emerged as an effective and safe way to decrease postoperative bleeding and transfusion rates. Although there is little doubt on the efficacy of the drug, the debate on ideal mode is more recent. We undertook this study to find out the most effective and yet safest way of TXA administration. Materials and Methods: A single institution - two hospital-based, double-blinded, prospective, randomized control trial was conducted from January 2015 to December 2015. One hundred and fifty patients were randomly divided in one of the three groups using computer-generated tables - intravenous (IV), intraarticular and combined. Evident loss through drain, total loss based on gross method and hemoglobin balance method, hidden blood losses, hemoglobin, and hematocrit drop, all possible complications related to TXA were evaluated and compared among groups. The analysis of variance and Tukey's post hoc were used for continuous outcome variables and Chi-square test for binary outcome variables. Results: Evident loss in combined group was 574.25 +/- 209.8 ml, significantly less than IV (685.4 +/- 289.9 ml) and intraarticular group (724.3 +/- 246.8 ml). Total loss was similarly least for combined group (930.1 +/ 262.2 ml) compared to IV (1208.3 +/- 368.8 ml) and intraarticular group (1198.1 +/- 356.8 ml). There were no transfusions in combined group compared to five in IV and four in intraarticular group. Combined group also had least hidden losses after surgery. No patients in any group developed symptomatic deep venous thrombosis. Conclusion: Combined administration of drug is most effective way to decrease postoperative bleeding and requirement of transfusion in unilateral TKA without increasing any risk of complications. PMID- 29576639 TI - Total Hip Arthroplasty by the Direct Anterior Approach Using a Neck-preserving Stem: Safety, efficacy and learning curve. AB - Background: The concept of femoral neck preservation in total hip replacement (THR) was introduced in 1993. It is postulated that retaining cortical bone of the femoral neck offers triplanar stability, uniform stress distribution, and accommodates physiological anteversion. However, data on safety, efficacy and learning curve are lacking. Materials and Methods: We prospectively assessed all patients who were operated for a THR with a short neck preserving stem (MiniHip) between 2012 and 2014. The safety and learning curve were assessed by recording operative time; stem size; and adverse events including periprosthetic fracture; paresthesia; and limb length discrepancy (LLD). The cohort was divided into equal groups to assess the learning curve effect, and the cumulative sums (CUSUM) test was performed to monitor intraoperative neck fractures. For assessment of efficacy, Oxford Hip Score (OHS) and Short Form-36 (SF-36) scores were compared preoperatively and postoperatively. Results: 138 patients with median age 62 years (range 35-82 years) were included with a median followup of 42 months (range 30-56 months). The minimum followup was 2.5 years. The OHS, SF-36 (physical and mental component) scores improved by a mean score of 26, 28, and 27 points, respectively. All patients had LLD of <10 mm (1.9 mm +/- 1.3). Adverse events included intraoperative neck fracture (n = 6), subsidence (n = 1), periprosthetic fracture (n = 1), paresthesia (n = 12), and trochanteric bursitis (n = 2). After early modification of the technique to use a smaller finishing broach, the CUSUM test demonstrated acceptable intraoperative neck fracture risk. The second surgery group had a reduced risk of intraoperative neck fracture (5/69 vs. 1/69 P = 0.2), reduced operative time (66 vs. 61 min, P = 0.06), and increased stem size (5 vs. 6, P = 0.09) although these differences were not statistically significant. Conclusions: The MiniHip stem is safe alternative to standard THR with good functional outcomes but with a learning curve for the surgical technique, implants sizing, and the risk of intraoperative neck fractures. PMID- 29576640 TI - Short Term Outcome of Varus Derotation Osteotomy in Late Presenting Perthes Disease. AB - Background: Untreated Perthes disease can lead to osteoarthritis by the fourth decade. The treatment is conservative for children <6 years, operative within the age group of 6-9 years. Late onset Perthes, older than 9 years or more, are notorious with the aggressive course with poor outcome. However, literature do not come to a consensus between conservative and operative management. This study evaluates the clinical and radiological outcome of varus derotation osteotomy (VDRO) in Perthes disease presenting late with age 8 years or more. Materials and Methods: 15 children (13 males and 2 females) with the mean age of 9.4 years belonging to modified Elizabethtown classification Stage IB, IIA, IIB treated with open wedge VDRO between 2008 and 2014 were included in this study. Seven patients (46.67%) were of >10 years of age at presentation. All patients had limitation of abduction and internal rotation. Eight patients (53.33%) had pain at the hip and 12 patients (80%) had limp. Mean time between diagnosis and corrective surgery was 3 weeks. Results: The evaluation was done using caput index (CI) and epiphyseal quotient (EQ) and articulotrochanteric distance radiologically, range of motion and Harris Hip Score for clinical outcome. All the measurements were carried out on pre- and postoperative X-rays after 3 years followup and compared with the contralateral normal hip. After a mean followup period of 3.4 years, we noted the statistically significant difference between pre- and postoperative values. We noted that all (100%) children in Stage IB, IIA and 50% children in Stage IIB achieved satisfactory results. There was a significant change (P = 0.000) in CI among all the patients after surgery. The final EQ after 3 years of VDRO was 0.606 and was significant (P = 0.0000). Conclusion: In our opinion, based on the encouraging short term radiological and clinical outcomes, VDRO may be regarded as a treatment procedure for late presenting Perthes disease in stage IB, IIA, IIB. PMID- 29576641 TI - Epidemiological Profile of Femoral Head Osteonecrosis in the North Indian Population. AB - Background: There are limited studies on the epidemiology of femoral head osteonecrosis in Indian population. This study was designed to look for the risk factors of osteonecrosis hip and to assess the severity as per radiological staging (Association Research Circulation Osseous [ARCO]) and clinical score (Harris hip score [HHS]). Materials and Methods: 249 patients (382 hips) of osteonecrosis femoral head (ONFH) who were evaluated at our center between January 1, 2005, and June 30, 2013, were included in this retrospective study. The details of history, clinical examination, radiological grading, and HHS were entered into a proforma. Results: The mean age was 34.71 years (range 14-70 years) and 70.28% (n=175) patients were between 20 and 40 years. Male to female ratio was 5:1. Bilateral ONFH was observed in 53.41% (n=133) patients. In atraumatic conditions, bilateral involvement was seen in 61.61% (130/211) patients. Steroid administration (37.3%, 93/249) was most commonly observed in the patients followed by idiopathic in 21.3% (53/249) patients, chronic alcohol consumption in 20.1% (50/249) patients, and trauma in 15.3% (38/249) patients. There were 48% (185/382) hips in ARCO Stage 2 followed by 33% (125/382) in Stage 3 and 16% (61/382) in Stage 4. The mean HHS was 80.97 +/- 14.35 in unilateral ONFH. The mean HHS was 72.79 +/- 14.43 and 80.07 +/- 13.52 in more involved hip and in less involved hip, respectively, in bilateral ONFH. The ARCO staging had statistically significant correlation with HHS (Pearson's correlation coefficient r = -0.783, P < 0.01) in unilateral ONFH patients and more severely affected hip in bilateral (Pearson's correlation coefficient r = -0.654, P < 0.01) ONFH, but it did not show any association with less involved hip in bilateral cases. Conclusion: ONFH in the North Indian patients is a disease of young individuals with male predominance. Steroid intake is most commonly observed in these patients followed by idiopathic, chronic alcohol consumption, and trauma. PMID- 29576642 TI - Comparative Study for Evaluating Efficacy of Fascia Iliaca Compartment Block for Alleviating Pain of Positioning for Spinal Anesthesia in Patients with Hip and Proximal Femur Fractures. AB - Background: Patient positioning for performing spinal blockade causes severe pain in hip and femur fracture. Adequate pain relief before administrating spinal blockade will increase patient's cooperation. This study was done to assess analgesic effect of fascia iliaca compartment block (FICB) for positioning for spinal anesthesia. Materials and Methods: This was a randomized, double blind, controlled prospective study that included 100 patients of the American Society of Anesthesiologists physical statuses I to III, of either sex, between 30 and 90 years, posted for hip or proximal femoral surgery, with visual analogue scale (VAS) >3 in preoperative period. The two groups were assigned randomly. In Group 1, FICB was given half an hour before shifting the patients in operation theater with 30 ml of 0.25% ropivacaine, and in Group 2, sham block was given with 30 ml normal saline. Each group included 50 patients. Thirty minutes after FICB, spinal anesthesia was given and patients' vitals were monitored before and after block, at the time of positioning for spinal anesthesia, intraoperative and postoperative periods. Results: In Group 1, mean VAS before FICB was 8.02 which reduced to 2.28, which is statistically significant (P = 7.8813E-50), whereas in Group 2, mean VAS before sham block was 7.98 which reduced to 7.90, which is statistically nonsignificant (P = 0.6694). Mean total duration of analgesia in Group 1 was 428.3 min after spinal anesthesia, whereas in Group 2, mean total duration of analgesia was 240.1 min. Conclusion: FICB effectively provides analgesia for positioning for spinal anesthesia to patients in hip and proximal femur surgeries. It also provides analgesia in postoperative period without having significant alteration in the hemodynamic profile of patients. PMID- 29576643 TI - Total Knee Arthroplasty Using Patient-specific Blocks after Prior Femoral Fracture without Hardware Removal. AB - Background: The options to perform total knee arthroplasty (TKA) with retained hardware in femur are mainly - removal of hardware, use of extramedullary guide, or computer-assisted surgery. Patient-specific blocks (PSBs) have been introduced with many potential advantages, but their use in retained hardware has not been adequately explored. The purpose of the present study was to outline and assess the usefulness of the PSBs in performing TKA in patients with retained femoral hardware. Materials and. Materials and Methods: Nine patients with retained femoral hardware underwent TKA using PSBs. All the surgeries were performed by the same surgeon using same implants. Nine cases (7 males and 2 females) out of total of 120 primary TKA had retained hardware. The average age of the patients was 60.55 years. The retained hardware were 6 patients with nails, 2 with plates and one patient had screws. Out of the nine cases, only one patient needed removal of a screw which was hindering placement of pin for the PSB. Results: All the patients had significant improvement in their Knee Society Score (KSS) which improved from 47.0 to postoperative KSS of 86.77 (P < 0.00). The mechanical axis was significantly improved (P < 0.03) after surgery. No patient required blood transfusion and the average tourniquet time was 41 min. Conclusion: TKA using PSBs is useful and can be used in patients with retained hardware with good functional and radiological outcome. PMID- 29576644 TI - Complex Tibial Plateau Fractures Treated by Hybrid External Fixation System: A correlation of followup computed tomography derived quality of reduction with clinical results. AB - Background: Tibial plateau fractures are common due to high energy injuries. The principles of treatment include respect for the soft tissues, restoring the congruity of the articular surface and reduction of the anatomic alignment of the lower limb to enable early movement of the knee joint. There are various surgical fixation methods that can achieve these principles of treatment. Recognition of the particular fracture pattern is important, as this guides the surgical approach required in order to adequately stabilize the fracture. This study evaluates the results of the combined treatment of external fixator and limited internal fixation along with the advantages using postoperative computed tomography (CT) scan after implant removal. Materials and. Methods: 55 patients with a mean age of 42 years (range 17-65 years) with tibial plateau fracture, were managed in our institution between October 2010 and September 2013., Twenty fractures were classified as Schatzker VI and 35 as Schatzker V. There were 8 open fractures (2 Gustilo Anderson 3A and 6 Gustilo Anderson 2). All fractures were treated with closed reduction and hybrid external fixation (n = 21/38.2%) or with minimal open reduction internal fixation and a hybrid system (n = 34/61.8%). After the removal of the fixators, CT-scan was programmed for all the cases, for correlation with the results. At final followup, the American Knee Society Score (AKSS) was administered. Results: All patients were evaluated with a minimum of 12 months (range 12-21 months) followup. Average time to union was 15.5 weeks (range 13-19 weeks). The postoperative joint congruity as evaluated in the postoperative CT-scan was <2 mm of articular step-off in 8 patients (14.5%), between 2 and 4 mm in 18 patients (32.7%) and over 4 mm in 29 (52.7%). The injured limb mechanical axis was restored within 5 degrees compared to the contralateral limb in 36 cases (65%) and with an angulation >5 degrees in 19 cases (35%). Patients with residual joint depression <3.5 mm had a 95% chance of having excellent AKSS knee score results and 80% chance of having excellent AKSS function scores. On the other hand, residual joint depression of >4.5 mm displayed a 100% chance of getting poor-fair scores both in AKSS knee and AKSS function score. The association of a postoperative mechanical axis within 5 degrees of the contralateral limb and improved knee scores was statistically significant for the AKSS function and total scores but not for the AKSS knee score. The AKSS was negatively correlated with postoperative joint depression magnitude which was statistically significant. Only the amount of joint collapse was verified as a prognostic factor in a multivariate logistic regression analysis. Conclusions: The postoperative CT-scan shows important information about bone healing, and an exact image of the reduction and the shaft alignment. Postoperative radiographs may have led to an underestimation of the degree of residual displacement. On the contrary, CT-scan demonstrates the exact grade of articular displacement and depending on CT-scan results one can better manage the postoperative rehabilitation. PMID- 29576645 TI - Anterior Cruciate Ligament Reconstruction with Tibial Attachment Preserving Hamstring Graft without Implant on Tibial Side. AB - Background: Tibial attachment preserving hamstring graft could prevent potential problems of free graft in anterior cruciate ligament (ACL) reconstruction such as pull out before graft-tunnel healing or rupture before ligamentization. Different implants have been reportedly used for tibial side fixation with this technique. We investigated short-term outcome of ACL reconstruction (ACLR) with tibial attachment sparing hamstring graft without implant on the tibial side by outside in technique. Materials and Methods: Seventy nine consecutive cases of ACL tear having age of 25.7 +/- 6.8 years were included after Institutional Board Approval. All subjects were male. The mean time interval from injury to surgery was of 7.5 +/- 6.4 months. Hamstring tendons were harvested with open tendon stripper leaving the tibial insertion intact. The free ends of the tendons were whip stitched, quadrupled, and whip stitched again over the insertion site of hamstring with fiber wire (Arthrex). Single bundle ACLR was done by outside in technique and the femoral tunnel was created with cannulated reamer. The graft was pulled up to the external aperture of femoral tunnel and fixed with interference screw (Arthrex). The scoring was done by Lysholm, Tegner, and KT 1000 by independent observers. All cases were followed up for 2 years. Results: The mean length of quadrupled graft attached to tibia was 127.65 +/- 7.5 mm, and the mean width was 7.52 +/- 0.78 mm. The mean preoperative Lysholm score of 47.15 +/- 9.6, improved to 96.8 +/- 2.4 at 1 year. All cases except two returned to the previous level of activity after ACLR. There was no significant difference statistically between preinjury (5.89 +/- 0.68) and postoperative (5.87 +/- 0.67) Tegner score. The anterior tibial translation (ATT) (KT 1000) improved from 11.44 +/- 1.93 mm to 3.59 +/- 0.89 mm. The ATT of operated knee returned to nearly the similar value as of the opposite knee (3.47 +/- 1.16 mm). The Pivot shift test was negative in all cases. None had a failure of graft till final followup. Conclusion: Attachment sparing hamstring graft without a tibial implant is a simple, cost-effective technique that provides a consistently satisfactory outcome. PMID- 29576646 TI - Sloppy Hinge Prosthetic Replacement in Old Healed Side Swipe Injuries of Elbow - Long term Results. AB - Background: Sideswipe injuries of elbow often poses significant functional loss resulting from devastating injuries involving osseoligamentous structures as well as multilevel soft tissue injuries around the elbow. Inspite of treatment, no conscientious treatment opinion is available in the literature to provide optimum functional outcome. The objective of this study is to evaluate the results of prosthetic replacement of old healed sideswipe injuries of elbow with gross dysfunctional disabilities resulting from loss of bones and muscles around the joint. Materials and Methods: Fourteen patients of 2-3 years old healed sideswipe injuries of the elbow, treated by Baksi sloppy hinge (original version in seven and recent version in seven) prosthetic replacement were evaluated. All had normal neurovascular status except two; one having ulnar nerve deficit the other median nerve in another. The mean age was 42.7 years (range 32-61 years). Results: The average followup period was 13.5 years (range 5.11-23.11 years). Ten patients regained stable 0 degrees to 130 degrees elbow flexion, and four had restricted terminal flexion with arc 10 degrees -115 degrees following V-Y plasty of contracted triceps. Mean supination was 22 degrees and mean pronation was 35 degrees . According to Mayo Elbow Performance Score (MEPS), excellent results were in five (35.7%), good in six (42.8%), and fair in one (7.1%). Two patients (14.2%) needed removal of prosthesis due to intractable delayed infection and considered failure. Following removal, the resected elbow retained relatively stable motions due to mature fibrous tissues connecting the adjacent bone ends and reorientation of muscle balance. Postoperative improvement of MEPS (mean 84) was significant (P = 0.0037) compared to preoperative value (mean 41.7). Two patients had superficial wound infection and five aseptic loosening of which one was symptomatic. Conclusion: Prosthetic replacement of elbow is an effective salvage procedure in old healed sideswipe injuries. PMID- 29576647 TI - A Scoring System to Demonstrate the Risk for Bone Injury in Patients with Clinically Suspected or Occult Scaphoid Fracture. AB - Background: It is important to diagnose a scaphoid fracture accurately and start the correct treatment in the shortest time possible. However, the fracture of bone may not be visible on x-ray. In such cases, patients are clinically diagnosed with suspected or occult scaphoid fractures. The aim of this study was to define a scoring system based on physical examination to demonstrate the risk for bone injury in patients with clinically suspected and occult scaphoid fractures with negative radiographs and anatomical snuff box tenderness and to decrease the costs and workforce loss due to unnecessary treatment and magnetic resonance imaging (MRI). Materials and Methods: Patients were initially evaluated by the attendant orthopedic physician in the emergency service with X-ray of the wrist, and ten wrist physical examination techniques were used. The X-rays of patients were evaluated by three orthopedic surgeons. Finally sixty patients, who were diagnosed as having no fracture by all three orthopedic surgeon, were included in the study. The wrists of these patients were evaluated with MRI. Results: There were 46 male (77%) and 14 female (23%) patients with a mean age of 21.5 years (range 7-61 years). About 3.3% had triquetrum fracture, 15% had bone edema in the scaphoid and radius, 18.3% had distal radius fracture, 31.6% had scaphoid fracture, and 31.8% had no bone injury. A scoring system was also proposed. It can be predicted that in the physical examination of the wrist if the total score is higher than 6.5, the probability of fracture is 2.87 (positive likelihood ratio) fold compared to scores below 6.5. Conclusions: Proposal of this new scoring system was thought to be useful for predicting the risk for bone injury in patients with clinically suspected scaphoid fractures and making decision regarding therapeutic options.

AB - Background: Irreducible atlantoaxial dislocation (IAAD) is a disorder of atlantoaxial joint instability with various causes. The diagnostic criteria for IAAD are variable. The diagnosis of IAAD is mainly based on preoperative and intraoperative traction results, as well as the physician's experience, with no relatively uniform guidelines for the selection of treatment. This study evaluates sagittal atlantoaxial joint inclination (SAAJI) and reduction index (RI) values for diagnosis and treatment of IAAD. Materials and Methods: 24 IAAD patients treated in our hospital from January 2008 to July 2014 were retrospectively analysed. Patients included were 13 males and 11 females, with a mean age of 43 years. The various causes for IAAD were atlantoaxial transverse ligament rupture (n=3), old dens fracture (n=15), occipitalization of the atlas (n=6). The patients were divided into two groups. group A underwent anterior release with posterior reduction and fixation; Group B underwent posterior reduction and fixation; 12 healthy individuals served as controls. SAAJI and atlas-dens interval (ADI) values before and after traction were measured, and RI was calculated. Imaging data were analyzed. Results: The mean SAAJI values were as follows: left, 5.6 +/- 1.9 degrees and right, 5.1 +/- 2.1 degrees in the control group; right, 39.5 +/- 6.0 degrees and left, 38.8 +/- 5.8 degrees in Group A; and right, 23.1 +/- 7.0 degrees and left, 23.9 +/- 6.1 degrees in Group B. There was no significant difference in the SAAJI values of the three groups (P < 0.05). The mean RIs in Groups A and B were 17.6 +/- 9.3% and 34.4 +/- 5.2%, respectively, and the difference was statistically significant (P < 0.05). There were obvious negative correlations between the SAAJI and RI values in Groups A and B. Conclusions: SAAJI and RI can be used as important imaging indicators to determine the reversibility of IAAD. If the RI value is >27.9% and SAAJI value is <32.5 degrees , reduction and fixation can be achieved by the posterior approach alone; otherwise, a combination of anterior and posterior approaches would be necessary.

AB - Background: Rapid prototyping (RP) is used widely in dental and faciomaxillary surgery with anecdotal uses in orthopedics. The purview of RP in orthopedics is vast. However, there is no error analysis reported in the literature on bone models generated using office-based RP. This study evaluates the accuracy of fused deposition modeling (FDM) using standard tessellation language (STL) files and errors generated during the fabrication of bone models. Materials and Methods: Nine dry bones were selected and were computed tomography (CT) scanned. STL files were procured from the CT scans and three-dimensional (3D) models of the bones were printed using our in-house FDM based 3D printer using Acrylonitrile Butadiene Styrene (ABS) filament. Measurements were made on the bone and 3D models according to data collection procedures for forensic skeletal material. Statistical analysis was performed to establish interobserver co relation for measurements on dry bones and the 3D bone models. Statistical analysis was performed using SPSS version 13.0 software to analyze the collected data. Results: The inter-observer reliability was established using intra-class coefficient for both the dry bones and the 3D models. The mean of absolute difference is 0.4 that is very minimal. The 3D models are comparable to the dry bones. Conclusions: STL file dependent FDM using ABS material produces near anatomical 3D models. The high 3D accuracy hold a promise in the clinical scenario for preoperative planning, mock surgery, and choice of implants and prostheses, especially in complicated acetabular trauma and complex hip surgeries. PMID- 29576650 TI - Histological Observation of the Retinacula of Weitbrecht and Its Clinical Significance: A cadaveric study. AB - Background: The retinacular arteries provide major supply to the femoral head, their injuries may lead to the femoral head necrosis (FHN) in femoral neck fractures. Although the femoral neck fracture was seriously displaced in some patients, FHN did not occur, which suggests that the blood supply is not fully blocked. This study was aimed to find the association between the structure of the retinacula of Weitbrecht and the mechanism of protecting retinacular arteries from being injured. Materials and Methods: Fourteen formalin-fixed cadaveric specimens (in 28 hips) with no significant vascular disease were observed. The retinacula were cut longitudinally and then cut into three parts: medial, middle, and lateral. These specimens were stained using hematoxylin and eosin and improved Masson Trichrome stain. The microstructure and tightness of the retinacula fixed to the bone and the distribution of vessels were examined under a stereoscope, an optical microscope, and a scanning electron microscope. Results: The microstructure and compactness in each part of retinacula were different, and the tightness of the fibers of the retinacula fixed to the bone in each part were different. A particular structure which resembled a Sandwich panels was observed, and it may be an effective mechanism of protecting retinacular arteries. Conclusion: The Sandwich panels structure existed generally in the retinacula of Weitbrecht, and this sandwich panelture may play very important role in protecting the retinaculum artery from being injured, which show the importance of protecting the retinacular artery in the treatment of femoral neck fractures.

AB - This paper develops the notion of "energy precarity" in order to uncover the governance practices and material conditions that drive and reproduce the inability of households to secure socially- and materially-necessitated levels of energy services in the home. The overarching aim is to foreground a geographical approach towards the study of domestic energy deprivation, by emphasizing the complex socio-spatial and material embeddedness of fuel poverty. The paper operationalizes these ideas via a field-based study of a group that has received limited attention in research and policy on fuel poverty: young adults living in privately rented accommodation. In evoking the experiences of such individuals, I employ energy precarity as a means of unpacking the spaces where energy deprivation is produced, experienced and contested. Among other findings, I highlight that people's fluid lifestyles and specific end-use energy demand patterns mean that energy deprivation metaphorically and physically overflows the limits of home, creating multiple performativities of precarity that have received very little attention to date.

AB - This study examines differences in the amount of economic support or mutual benefit derived from extended family living arrangements by studying differences in monetary contributions to essential household expenditures across family units in extended family households. Using the 2008 Survey of Income and Program Participation, multivariate regression and selection models are estimated to assess racial differences in family contributions toward household expenses in extended family households. Extended family households have very unequal monetary contributions towards household rent and utilities, although Hispanics have less unequal monetary contributions compared to other racial groups. Hispanic and Asians extended family households experience decreasing inequality in financial contributions as the income of each family increases whereas no relationship between financial contributions and income is found for whites or blacks. This suggests a different cultural orientation to extended family living arrangements for Asians and Hispanics compared to non-Hispanic whites.

AB - Unintended pregnancies disproportionately occur among teenage women, yet little is known about the determinants of pregnancy desire among this group. We use a comprehensive baseline survey and weekly data on pregnancy desires to investigate which unmarried 18-20 year-old women want a pregnancy, want to avoid pregnancy, and report consistent pregnancy desire and disinclination. Variables that positively predict pregnancy desire generally negatively predict desire to avoid pregnancy. While most young women have no desire and strong disinclination in most weeks, childhood receipt of public assistance is a strong predictor of wanting pregnancy and not wanting to avoid it. Comparing nested models suggests that the effects of childhood disadvantage operate through social environments where early pregnancy is less stigmatized. Young women in serious relationships, who are depressed, and who are not pursuing post-secondary education have more desire for pregnancy and less disinclination, but little of childhood disadvantage is mediated by these factors.

AB - Abstract: In this contribution, we present new insights and a critical discussion in the optical detection of saxitoxin using fluorophores with crown ethers. Fluorescence enhancement is caused by the reduction of photoinduced electron transfer upon complexation with the analyte. Our attempts to improve this detection method neither did yield a functioning sensor nor were the attempts to reproduce published data in this area successful. Due to the fact that only low concentrations of saxitoxin are available, multiple surrogates were investigated at high concentrations. However, no turn on response was observed. Moreover, a fluorescent decomposition product of saxitoxin that forms under UV light was discovered which was in our opinion misinterpreted as a sensor response by previous publications.

AB - Abstract: We have investigated the photo-induced reduction of Cu2+-Cu0 using benzil/triethylamine mixtures. The formation of elemental Cu is indicated by the appearance of its characteristic plasmon absorption peaks at 515 nm and 620 nm. Importantly, the nature of the counterion of the Cu2+ salt affects the reduction process. In the presence of Cl-, the reduction proceeds faster than with SO42-. Photo-induced electron transfer between excited benzil and triethylamine leads to the benzil radical anion, which acts as the reducing agent for Cu2+ and generates Cu0.

AB - Our quest to isolate and characterize natural products with in vitro solid tumor selectivity is driven by access to repositories of Indo-Pacific sponge extracts. In this project an extract of a species of Haplosclerida sponge obtained from the US NCI Natural Products Repository displayed, by in vitro disk diffusion assay (DDA) and IC50 determinations, selective cytotoxicity with modest potency to a human pancreatic cancer cell line (PANC-1) relative to the human lymphoblast leukemia cell line (CCRF-CEM). Two brominated indoles, the known 6-bromo conicamin (1) and the new derivative, 6-Br-8-keto-conicamin A (2), were identified and 2 (IC50 1.5 MUM for the natural product vs 4.1 MUM for the synthetic material) was determined to be responsible for the cytotoxic activity of the extract against the PANC-1 tumor cell line. The new natural product and ten additional analogs were prepared for further SAR testing. PMID- 29576662 TI - Situating Green Infrastructure in Context: A Framework for Adaptive Socio Hydrology in Cities. AB - Management of urban hydrologic processes using green infrastructure (GI) has largely focused on stormwater management. Thus, design and implementation of GI usually rely on physical site characteristics and local rainfall patterns, and do not typically account for human or social dimensions. This traditional approach leads to highly centralized stormwater management in a disconnected urban landscape, and can deemphasize additional benefits that GI offers, such as increased property value, greenspace aesthetics, heat island amelioration, carbon sequestration, and habitat for biodiversity. We propose a Framework for Adaptive Socio-Hydrology (FrASH) in which GI planning and implementation moves from a purely hydrology-driven perspective to an integrated socio-hydrological approach. This allows for an iterative, multifaceted decision-making process that would enable a network of stakeholders to collaboratively set a dynamic, context-guided project plan for the installation of GI, rather than a 'one-size-fits-all' installation. We explain how different sectors (e.g., governance, non governmental organizations, academia, and industry) can create a connected network of organizations that work towards a common goal. Through a graphical Chambered Nautilus model, FrASH is experimentally applied to contrasting GI case studies and shows that this multi-stakeholder, connected, de-centralized network with a co-evolving decision-making project plan results in enhanced multi functionality, potentially allowing for the management of resilience in urban systems at multiple scales.

AB - Distributing subsidized health products through existing health infrastructure could substantially and cost-effectively improve health in sub-Saharan Africa. There is, however, widespread concern that poor governance - in particular, limited health worker accountability - seriously undermines the effectiveness of subsidy programs. We audit targeted bednet distribution programs to quantify the extent of agency problems. We find that around 80% of the eligible receive the subsidy as intended, and up to 15% of subsidies are leaked to ineligible people. Supplementing the program with simple financial or monitoring incentives for health workers does not improve performance further and is thus not cost effective in this context.

AB - Selective laser sintering (SLS) is an efficient process in additive manufacturing that enables rapid part production from computer-based designs. However, SLS is limited by its notable lack of in-situ process monitoring when compared to other manufacturing processes. We report the incorporation of optical coherence tomography into an SLS system in detail and demonstrate access to surface and sub surface features. Video frame rate cross-sectional imaging reveals areas of sintering uniformity and areas of excessive heat error with high temporal resolution. We propose a set of image processing techniques for SLS process monitoring with OCT and report the limitations and obstacles for further OCT integration with SLS systems.

AB - We report Magnetospheric Multiscale observations of electron pressure gradient electric fields near a magnetic reconnection diffusion region using a new technique for extracting 7.5 ms electron moments from the Fast Plasma Investigation. We find that the deviation of the perpendicular electron bulk velocity from E * B drift in the interval where the out-of-plane current density is increasing can be explained by the diamagnetic drift. In the interval where the out-of-plane current is transitioning to in-plane current, the electron momentum equation is not satisfied at 7.5 ms resolution. PMID- 29576667 TI - Multimodel Evidence for an Atmospheric Circulation Response to Arctic Sea Ice Loss in the CMIP5 Future Projections. AB - Previous single-model experiments have found that Arctic sea ice loss can influence the atmospheric circulation. To evaluate this process in a multimodel ensemble, a novel methodology is here presented and applied to infer the influence of Arctic sea ice loss in the CMIP5 future projections. Sea ice influence is estimated by comparing the circulation response in the RCP8.5 scenario against the circulation response to sea surface warming and CO2 increase inferred from the AMIPFuture and AMIP4xCO2 experiments, where sea ice is unperturbed. Multimodel evidence of the impact of sea ice loss on midlatitude atmospheric circulation is identified in late winter (January-March), when the sea ice-related surface heat flux perturbation is largest. Sea ice loss acts to suppress the projected poleward shift of the North Atlantic jet, to increase surface pressure in northern Siberia, and to lower it in North America. These features are consistent with previous single-model studies, and the present results indicate that they are robust to model formulation. PMID- 29576668 TI - Urban Greenspace is Associated with Reduced Psychological Stress among Adolescents: A Geographic Ecological Momentary Assessment (GEMA) Analysis of Activity Space. AB - This study investigates the momentary association between urban greenspace, captured using Normalized Difference Vegetation Index (NDVI) derived from Landsat imagery, and psychological stress, captured using Geographic Ecological Momentary Assessment (GEMA), in the activity spaces of a sample of primarily African American adolescents residing in Richmond, Virginia. We employ generalized estimating equations (GEE) to estimate the effect of exposure to urban greenspace on stress and test for moderation by sex, emotional dysregulation, season, neighborhood disadvantage, and whether the observation occurs at home or elsewhere. Results indicate that urban greenspace is associated with lower stress when subjects are away from home, which we speculate is due to the properties of stress reduction and attention restoration associated with exposure to natural areas, and to the primacy of other family dynamics mechanisms of stress within the home. Subjects may also seek out urban greenspaces at times of lower stress or explicitly for purposes of stress reduction. The greenspace-stress association away from home did not differ by sex, emotional dysregulation, neighborhood disadvantage, or season, the latter of which suggests that the observed greenspace-stress relationship is associated with being in a natural environment rather than strictly exposure to abundant green vegetation. Given the association of urban greenspace with lower stress found here and in other studies, future research should address the mediated pathways between greenspace, stress, and stress-related negative health outcomes for different population subgroups as a means toward understanding and addressing health disparities. PMID- 29576669 TI - Parent-reported stigma and child anxiety: A mixed methods research study. AB - Background: Stigma has been frequently cited as a barrier to service use for various mental health problems. Studies suggest that stigma may be greater for childhood mental health problems that are perceived as more atypical. Aims: This study utilized a mixed methods research design (qual + QUAN) to examine parental endorsement of stigma and its impact on service utilization among children with significant anxiety-a common childhood problem frequently perceived as normative. Methods: Semi-structured qualitative interviews were conducted with 29 parents of anxious children. Qualitative data were coded using a grounded theory approach, and stigma-related responses were examined for emergent themes. Quantitative data was analyzed with frequency counts and chi-square analysis. Results: Stigma related to children's anxiety symptoms and seeking mental health services was reported by 41.3% (n = 12) of parents. Emergent themes included: 1) Parental Concern for Negative Consequences, 2) Parent Internalized Stigma, and 3) Negative Associations with Mental Health Treatment. Latino parents discussed stigma more frequently than non-Latino White parents (70% vs. 17.6%, respectively, X2(1, N = 27) = 5.33, p < 0.05). Conclusions: Although anxiety is a common childhood problem, stigma is still frequently reported by parents and may be an important barrier to mental health service use, especially among Latino youth.

AB - The natural radioactivities of five characteristic igneous rocks of the eastern foreland of the Opava Mountains (Eastern Sudetes, Poland), obtained in the laboratory and under in situ conditions, are presented. The activity concentrations of 232Th, 238U, and 40K were measured using an HPGe gamma-ray spectrometry system. The ranges of the activity concentrations of 232Th were 7-71 Bq kg-1 in the laboratory and 6-68 Bq kg-1 for the in situ measurements. For 238U, the ranges of the activity concentrations were 5-52 Bq kg-1 in the laboratory and 9-48 Bq kg-1 for the in situ measurements, and for 40K, the ranges were 520-1560 Bq kg-1 in the laboratory and 537-1700 Bq kg-1 for the in situ measurements. These determined activity concentrations were compared with the average activity concentrations of the radionuclides in similar types of rocks and with data from the Sudetes available in the literature. No significant differences were found between the in situ and laboratory measurements. PMID- 29576671 TI - First identification and characterization of Borrobol-type tephra in the Greenland ice cores: new deposits and improved age estimates. AB - Contiguous sampling of ice spanning key intervals of the deglaciation from the Greenland ice cores of NGRIP, GRIP and NEEM has revealed three new silicic cryptotephra deposits that are geochemically similar to the well-known Borrobol Tephra (BT). The BT is complex and confounded by the younger closely timed and compositionally similar Penifiler Tephra (PT). Two of the deposits found in the ice are in Greenland Interstadial 1e (GI-1e) and an older deposit is found in Greenland Stadial 2.1 (GS-2.1). Until now, the BT was confined to GI-1-equivalent lacustrine sequences in the British Isles, Sweden and Germany, and our discovery in Greenland ice extends its distribution and geochemical composition. However, the two cryptotephras that fall within GI-1e ice cannot be separated on the basis of geochemistry and are dated to 14358 +/- 177 a b2k and 14252 +/- 173 a b2k, just 106 +/- 3 years apart. The older deposit is consistent with BT age estimates derived from Scottish sites, while the younger deposit overlaps with both BT and PT age estimates. We suggest that either the BT in Northern European terrestrial sequences represents an amalgamation of tephra from both of the GI-1e events identified in the ice-cores or that it relates to just one of the ice-core events. A firm correlation cannot be established at present due to their strong geochemical similarities. The older tephra horizon, found within all three ice cores and dated to 17326 +/- 319 a b2k, can be correlated to a known layer within marine sediment cores from the North Iceland Shelf (ca. 17179-16754 cal a BP). Despite showing similarities to the BT, this deposit can be distinguished on the basis of lower CaO and TiO2 and is a valuable new tie-point that could eventually be used in high-resolution marine records to compare the climate signals from the ocean and atmosphere. PMID- 29576672 TI - Cumulative stress restricts niche filling potential of habitat-forming kelps in a future climate. AB - Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.Here, we explore the stress physiology of two coexisting kelps undergoing opposing range shifts in the Northeast Atlantic and discuss what differences in stress physiology may mean for future niche filling.We used chlorophyll florescence (Fv/Fm) and differentiation of the heat shock response (HSR) to determine the capacity of the expanding kelp, Laminaria ochroleuca, to move into the higher shore position of the retreating kelp, Laminaria digitata. We applied both single and consecutive exposures to immersed and emersed high and low temperature treatments, replicating low tide exposures experienced in summer and winter.No interspecific differences in HSR were observed which was surprising given the species' different biogeographic distributions. However, chlorophyll florescence revealed clear differences between species with L. ochroleuca better equipped to tolerate high immersed temperatures but showed little capacity to tolerate frosts or high emersion temperatures.Many patterns observed were only apparent after consecutive exposures. Such cumulative effects have largely been overlooked in tolerance experiments on intertidal organisms despite being more representative of the stress experienced in natural habitats. We therefore suggest future experiments incorporate consecutive stress into their design.Climate change is predicted to result in fewer ground frosts and increased summer temperatures. Therefore, L. ochroleuca may be released from its summer cold limit in winter but still be prevented from moving up the shore due to desiccation in the summer. Laminaria ochroleuca will, however, likely be able to move into tidal pools. Therefore, only partial niche filling by L. ochroleuca will be possible in this system as climate change advances.

PMID- 29576673 TI - Trophic consequences of introduced species: Comparative impacts of increased interspecific versus intraspecific competitive interactions. AB - Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on resident species, results are equivocal. In addition, quantifying the relative strength of impacts from non-native species (interspecific competition) versus the release of native conspecifics (intraspecific competition) is important but rarely completed.Two model non-native fishes, the globally invasive Cyprinus carpio and Carassius auratus, and the model native fish Tinca tinca, were used in a pond experiment to test how increased intra- and interspecific competition influenced trophic niches and somatic growth rates. This was complemented by samples collected from three natural fish communities where the model fishes were present. The isotopic niche, calculated using stable isotope data, represented the trophic niche.The pond experiment used additive and substitutive treatments to quantify the trophic niche variation that resulted from intra- and interspecific competitive interactions. Although the trophic niche sizes of the model species were not significantly altered by any competitive treatment, they all resulted in patterns of interspecific niche divergence. Increased interspecific competition caused the trophic niche of T. tinca to shift to a significantly higher trophic position, whereas intraspecific competition caused its position to shift towards elevated delta13C. These patterns were independent of impacts on fish growth rates, which were only significantly altered when interspecific competition was elevated.In the natural fish communities, patterns of trophic niche partitioning between the model fishes was evident, with no niche sharing. Comparison of these results with those of the experiment revealed the most similar results between the two approaches were for the niche partitioning between sympatric T. tinca and C. carpio.These results indicate that trophic niche divergence facilitates the integration of introduced species into food webs, but there are differences in how this manifests between introductions that increase inter- and intraspecific competition. In entirety, these results suggest that the initial ecological response to an introduction appears to be a trophic re-organisation of the food web that minimises the trophic interactions between competing species.

AB - Despite considerable field-based innovation and academic scrutiny, the nexus between conservation approaches, local support for parks and park effectiveness remains quite puzzling. Common approaches to understanding notions of environmental justice are to understand distributional and procedural issues, representation in decision making, and recognition of authorities and claims. We took a different approach and analysed environmental justice claims through institutional, ideational and psychological lenses. We sought to understand how the national park could have such broad support from local communities despite their acknowledgement that it severely curtailed their livelihoods. We conducted 100 household interviews in three villages that border Nam Et-Phou Louey National Protected Area. Our study found that villagers 1) hold on to broken promises by the State for agricultural activities and alternative revenues without fully changing forest use behaviours; 2) were influenced heavily by the 'educational' programmes by the State; 3) accepted the authority of the State and lack of participation in decision-making based on historical experiences and values; 4) justified their burdens by over-emphasising the positive aspects of the park. Our findings present a complementary framework to explain environmental justice claims, allowing for a nuanced analysis of how people respond to justices and injustices, and specifically how injustices can be identified through proven social science concepts.

AB - Why are some youth more likely to think of themselves as a science kind of person than others? In this paper, we use a cognitive social-theoretical framework to assess disparities in science identity among middle school-age youth in the United States. We investigate how discovery orientation is associated with science interest, perceived ability, importance, and reflected appraisal, and how they are related to whether youth see themselves, and perceive that others see them, as a science kind of person. We surveyed 441 students in an ethnically diverse, low-income middle school. Gender and race/ethnicity are associated with science identity but not with discovery orientation. Structural equation model results show that the positive association between discovery orientation and science identity is mediated by science interest, importance, and reflected appraisal. These findings advance understanding of how science attitudes and recognition may contribute to the underrepresentation of girls and/or minorities in science.

PMID- 29576679 TI - Comparing Different Approaches for Subtyping Children with Conduct Problems: Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct. AB - The aim of this study was to compare two youth psychopathy models (i.e., callous unemotional versus multidimensional model) in their ability to predict future and stable conduct problems (CP). At baseline, mothers and fathers of 321 boys and 369 girls (ages 7-12) completed measures that tap callous-unemotional and other psychopathic traits. Parent-reported CP was collected at baseline and at 6- and 12 month follow-ups. Children were assigned to mutually exclusive groups based on their levels of CP and psychopathic traits. Children with CP who manifested callous-unemotional traits (Callous-Unemotional + CP) were occasionally at risk for future and stable CP. Yet, across gender, children with CP scoring high on all psychopathic trait dimensions (Psychopathic Personality + CP) showed the most robust and highest risk for future and stable CP. Also, Callous-Unemotional + CP children, and children who were only high in CP, often were at similar risk for future CP. The findings suggest that the callous-unemotional model is less sufficient than the multidimensional model in predicting future and stable CP. This can be concluded for both boys and girls and calls for more research reconsidering the multidimensional nature of psychopathy for CP subtyping purposes. PMID- 29576676 TI - Evolution of sex-specific pace-of-life syndromes: genetic architecture and physiological mechanisms. AB - Sex differences in life history, physiology, and behavior are nearly ubiquitous across taxa, owing to sex-specific selection that arises from different reproductive strategies of the sexes. The pace-of-life syndrome (POLS) hypothesis predicts that most variation in such traits among individuals, populations, and species falls along a slow-fast pace-of-life continuum. As a result of their different reproductive roles and environment, the sexes also commonly differ in pace-of-life, with important consequences for the evolution of POLS. Here, we outline mechanisms for how males and females can evolve differences in POLS traits and in how such traits can covary differently despite constraints resulting from a shared genome. We review the current knowledge of the genetic basis of POLS traits and suggest candidate genes and pathways for future studies. Pleiotropic effects may govern many of the genetic correlations, but little is still known about the mechanisms involved in trade-offs between current and future reproduction and their integration with behavioral variation. We highlight the importance of metabolic and hormonal pathways in mediating sex differences in POLS traits; however, there is still a shortage of studies that test for sex specificity in molecular effects and their evolutionary causes. Considering whether and how sexual dimorphism evolves in POLS traits provides a more holistic framework to understand how behavioral variation is integrated with life histories and physiology, and we call for studies that focus on examining the sex specific genetic architecture of this integration. PMID- 29576680 TI - Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct as Predictors of Various Antisocial Outcomes During Early Adolescence. AB - The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12 year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1-3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality + CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional + CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes. PMID- 29576681 TI - Psychopathic Personality Works Better than CU Traits for Predicting Fearlessness and ADHD Symptoms among Children with Conduct Problems. AB - Children with early-onset conduct problems (CP) are at great risk for future behavior problems, and this risk seems to increase when CP co-occur with psychopathic traits. Even though studies are indicating that the entire psychopathic personality construct may be more useful in designating a meaningful subgroup of children with CP, research on psychopathic traits and CP in childhood have mainly focused on the role of callous unemotional (CU) traits. Prospective longitudinal data of 1867 3- to 5-year-olds (47% girls) followed annually for two years was used to compare groups of children with different combinations of CP and psychopathic traits on fearlessness and Attention-Deficit Hyperactivity Disorder (ADHD) symptoms. Children with CP and psychopathic personality had higher baseline and stable levels of ADHD symptoms than children with CP only or children with CP and concurrent CU traits, while baseline levels of fearlessness did not differ. They were also more likely to display stable levels of the risky combination of CP and ADHD symptoms. Results were similar for boys and girls. Findings indicate that there are reasons to consider other traits and behaviors as specifiers for subgroups of children with CP over and above CU traits, in order to optimize both diagnostic practice and treatment outcomes.

AB - Geographically isolated wetlands, those entirely surrounded by uplands, provide numerous landscape-scale ecological functions, many of which are dependent on the degree to which they are hydrologically connected to nearby waters. There is a growing need for field-validated, landscape-scale approaches for classifying wetlands on the basis of their expected degree of hydrologic connectivity with stream networks. This study quantified seasonal variability in surface hydrologic connectivity (SHC) patterns between forested Delmarva bay wetland complexes and perennial/intermittent streams at 23 sites over a full-water year (2014-2015). Field data were used to develop metrics to predict SHC using hypothesized landscape drivers of connectivity duration and timing. Connection duration was most strongly related to the number and area of wetlands within wetland complexes as well as the channel width of the temporary stream connecting the wetland complex to a perennial/intermittent stream. Timing of SHC onset was related to the topographic wetness index and drainage density within the catchment. Stepwise regression modelling found that landscape metrics could be used to predict SHC duration as a function of wetland complex catchment area, wetland area, wetland number, and soil available water storage (adj-R 2 = 0.74, p < .0001). Results may be applicable to assessments of forested depressional wetlands elsewhere in the U.S. Mid-Atlantic and Southeastern Coastal Plain, where climate, landscapes, and hydrological inputs and losses are expected to be similar to the study area.

AB - Coccolithophores are a critical component of global biogeochemistry, export fluxes, and seawater optical properties. We derive globally significant relationships to estimate integrated coccolithophore and coccolith concentrations as well as integrated concentrations of particulate inorganic carbon (PIC) from their respective surface concentration. We also examine surface versus integral relationships for other biogeochemical variables contributed by all phytoplankton (e.g., chlorophyll a and particulate organic carbon) or diatoms (biogenic silica). Integrals are calculated using both 100 m integrals and euphotic zone integrals (depth of 1% surface photosynthetically available radiation). Surface concentrations are parameterized in either volumetric units (e.g., m-3) or values integrated over the top optical depth. Various relationships between surface concentrations and integrated values demonstrate that when surface concentrations are above a specific threshold, the vertical distribution of the property is biased to the surface layer, and when surface concentrations are below a specific threshold, the vertical distributions of the properties are biased to subsurface maxima. Results also show a highly predictable decrease in explained-variance as vertical distributions become more vertically heterogeneous. These relationships have fundamental utility for extrapolating surface ocean color remote sensing measurements to 100 m depth or to the base of the euphotic zone, well beyond the depths of detection for passive ocean color remote sensors. Greatest integrated concentrations of PIC, coccoliths, and coccolithophores are found when there is moderate stratification at the base of the euphotic zone.

AB - The Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) updates NASA's previous satellite era (1980 - onward) reanalysis system to include additional observations and improvements to the Goddard Earth Observing System, Version 5 (GEOS-5) Earth system model. As a major step towards a full Integrated Earth Systems Analysis (IESA), in addition to meteorological observations, MERRA-2 now includes assimilation of aerosol optical depth (AOD) from various ground- and space-based remote sensing platforms. Here, in the first of a pair of studies, we document the MERRA-2 aerosol assimilation, including a description of the prognostic model (GEOS-5 coupled to the GOCART aerosol module), aerosol emissions, and the quality control of ingested observations. We provide initial validation and evaluation of the analyzed AOD fields using independent observations from ground, aircraft, and shipborne instruments. We demonstrate the positive impact of the AOD assimilation on simulated aerosols by comparing MERRA-2 aerosol fields to an identical control simulation that does not include AOD assimilation. Having shown the AOD evaluation, we take a first look at aerosol-climate interactions by examining the shortwave, clear-sky aerosol direct radiative effect. In our companion paper, we evaluate and validate available MERRA-2 aerosol properties not directly impacted by the AOD assimilation (e.g. aerosol vertical distribution and absorption). Importantly, while highlighting the skill of the MERRA-2 aerosol assimilation products, both studies point out caveats that must be considered when using this new reanalysis product for future studies of aerosols and their interactions with weather and climate.

AB - The representation of extratropical cyclones (ETCs) precipitation in general circulation models (GCMs) and a weather research and forecasting (WRF) model is analyzed. This work considers the link between ETC precipitation and dynamical strength and tests if parameterized convection affects this link for ETCs in the North Atlantic Basin. Lagrangian cyclone tracks of ETCs in ERA-Interim reanalysis (ERAI), the GISS and GFDL CMIP5 models, and WRF with two horizontal resolutions are utilized in a compositing analysis. The 20-km resolution WRF model generates stronger ETCs based on surface wind speed and cyclone precipitation. The GCMs and ERAI generate similar composite means and distributions for cyclone precipitation rates, but GCMs generate weaker cyclone surface winds than ERAI. The amount of cyclone precipitation generated by the convection scheme differs significantly across the datasets, with GISS generating the most, followed by ERAI and then GFDL. The models and reanalysis generate relatively more parameterized convective precipitation when the total cyclone-averaged precipitation is smaller. This is partially due to the contribution of parameterized convective precipitation occurring more often late in the ETC life cycle. For reanalysis and models, precipitation increases with both cyclone moisture and surface wind speed, and this is true if the contribution from the parameterized convection scheme is larger or not. This work shows that these different models generate similar total ETC precipitation despite large differences in the parameterized convection, and these differences do not cause unexpected behavior in ETC precipitation sensitivity to cyclone moisture or surface wind speed. PMID- 29576686 TI - How do Rumination and Social Problem Solving Intensify Depression? A Longitudinal Study. AB - In order to examine how rumination and social problem solving intensify depression, the present study investigated longitudinal associations among each dimension of rumination and social problem solving and evaluated aspects of these constructs that predicted subsequent depression. A three-wave longitudinal study, with an interval of 4 weeks between waves, was conducted. Japanese university students completed the Beck Depression Inventory-Second Edition, Ruminative Responses Scale, Social Problem-Solving Inventory-Revised Short Version, and Interpersonal Stress Event Scale on three occasions 4 weeks apart (n = 284 at Time 1, 198 at Time 2, 165 at Time 3). Linear mixed models were analyzed to test whether each variable predicted subsequent depression, rumination, and each dimension of social problem solving. Rumination and negative problem orientation demonstrated a mutually enhancing relationship. Because these two variables were not associated with interpersonal conflict during the subsequent 4 weeks, rumination and negative problem orientation appear to strengthen each other without environmental change. Rumination and impulsivity/carelessness style were associated with subsequent depressive symptoms, after controlling for the effect of initial depression. Because rumination and impulsivity/carelessness style were not concurrently and longitudinally associated with each other, rumination and impulsive/careless problem solving style appear to be independent processes that serve to intensify depression. PMID- 29576687 TI - Glyphosate dose modulates the uptake of inorganic phosphate by freshwater cyanobacteria. AB - The usefulness of glyphosate [N-(phosphonomethyl)glycine] as a source of nutritive phosphorus for species of halophilic cyanobacteria has been postulated for years. Our results indicate a stimulating effect of glyphosate on the growth of four out of five examined freshwater species, Anabaena variabilis (CCALA 007), Chroococcus minutus (CCALA 055), Fischerella cf. maior (CCALA 067) and Nostoc cf. muscorum (CCALA 129), in a manner dependent on the applied concentration. The most significant stimulation was observed at a dose of 0.1 mM glyphosate. The decrease in the amount of phosphonate, which correlated with microbial growth, demonstrated that glyphosate may play an important role in cyanobacterial nourishment. Surprisingly, the consumption of organic phosphorus did not start when concentrations of inorganic phosphate (PO43-) had fallen dramatically; instead, the assimilation of both types of phosphorus occurred simultaneously. The greatest decrease in the amount of glyphosate was observed during the first week. The uptake of the standard nutrient-phosphate (PO43-), was strongly dependent on the xenobiotic concentration. When a concentration of 0.1 mM glyphosate was used, the consumption of phosphate decreased in favour of glyphosate assimilation. Our study revealed for the very first time that the presence of inorganic phosphate significantly enhances the bioavailability of glyphosate. Statistical analysis confirmed that the nutritive usage of glyphosate and the absorption of phosphate are features associated with the herbicide concentration rather than features related to the species of freshwater cyanobacterium. This finding supports the thesis of an important role of organic phosphorus in the formation of cyanobacterial blooms and creates the opportunity of using these cyanobacteria to bind both organic and inorganic forms of phosphorus in microalgal biomasses. PMID- 29576688 TI - Valuable natural products from marine and freshwater macroalgae obtained from supercritical fluid extracts. AB - The biologically active compounds (fatty acids, pigments, phenolics, and flavonoid content) were studied in supercritical fluid extracts from the biomass of marine (Ulva clathrata, Cladophora glomerata, Polysiphonia fucoides, and their multi-species mixture) and freshwater (C. glomerata) macroalgae. Different extraction techniques were used in order to compare differences in the biologically active compound composition of the macroalgal extracts. The results indicated that the saturated and unsaturated fatty acids ranged from C9:0 to C22:0. The analysis of differences in the composition of unsaturated to saturated fatty acids in extracts showed that palmitic acid (C16:0) and oleic acid (C18:1, n-9) reached the highest value not only in marine monospecies and multi-species biomass but also in the freshwater macroalga C. glomerata. When comparing the similarity between the concentration of fatty acids and the ratio of the concentration of unsaturated fatty acids to saturated in macroalgal extracts, we found small but not statistically significant variations in values between years (up to 10%). This is acceptable for applications as a stable raw material for industrial purposes. Significantly higher values of fatty acids, carotenoids, and chlorophylls were obtained in the case of SC-CO2 extraction. The active ingredients of polyphenols, possessing antioxidant activity ranged from approximately 2-4%. Moreover, flavonoids represented less than 10% of the total content of polyphenolic compounds. The extraction efficiency of polyphenols was higher from a mixture of marine algae for the ultrasound-assisted extraction compared to freshwater. All these findings show that marine and freshwater macroalgae, as a raw material, have the optimal biologically active compounds composition for cosmetics. PMID- 29576689 TI - Application of feature selection methods for automated clustering analysis: a review on synthetic datasets. AB - The effective modelling of high-dimensional data with hundreds to thousands of features remains a challenging task in the field of machine learning. This process is a manually intensive task and requires skilled data scientists to apply exploratory data analysis techniques and statistical methods in pre processing datasets for meaningful analysis with machine learning methods. However, the massive growth of data has brought about the need for fully automated data analysis methods. One of the key challenges is the accurate selection of a set of relevant features, which can be buried in high-dimensional data along with irrelevant noisy features, by choosing a subset of the complete set of input features that predicts the output with higher accuracy comparable to the performance of the complete input set. Kohonen's self-organising neural network map has been utilised in various ways for this task, such as with the weighted self-organising map (WSOM) approach and this method is reviewed for its efficacy. The study demonstrates that the WSOM approach can result in different results on different runs on a given dataset due to the inappropriate use of the steepest descent optimisation method to minimise the weighted SOM's cost function. An alternative feature weighting approach based on analysis of the SOM after training is presented; the proposed approach allows the SOM to converge before analysing the input relevance, unlike the WSOM that aims to apply weighting to the inputs during the training which distorts the SOM's cost function, resulting in multiple local minimums meaning the SOM does not consistently converge to the same state. We demonstrate the superiority of the proposed method over the WSOM and a standard SOM in feature selection with improved clustering analysis. PMID- 29576690 TI - Deep imitation learning for 3D navigation tasks. AB - Deep learning techniques have shown success in learning from raw high-dimensional data in various applications. While deep reinforcement learning is recently gaining popularity as a method to train intelligent agents, utilizing deep learning in imitation learning has been scarcely explored. Imitation learning can be an efficient method to teach intelligent agents by providing a set of demonstrations to learn from. However, generalizing to situations that are not represented in the demonstrations can be challenging, especially in 3D environments. In this paper, we propose a deep imitation learning method to learn navigation tasks from demonstrations in a 3D environment. The supervised policy is refined using active learning in order to generalize to unseen situations. This approach is compared to two popular deep reinforcement learning techniques: deep-Q-networks and Asynchronous actor-critic (A3C). The proposed method as well as the reinforcement learning methods employ deep convolutional neural networks and learn directly from raw visual input. Methods for combining learning from demonstrations and experience are also investigated. This combination aims to join the generalization ability of learning by experience with the efficiency of learning by imitation. The proposed methods are evaluated on 4 navigation tasks in a 3D simulated environment. Navigation tasks are a typical problem that is relevant to many real applications. They pose the challenge of requiring demonstrations of long trajectories to reach the target and only providing delayed rewards (usually terminal) to the agent. The experiments show that the proposed method can successfully learn navigation tasks from raw visual input while learning from experience methods fail to learn an effective policy. Moreover, it is shown that active learning can significantly improve the performance of the initially learned policy using a small number of active samples. PMID- 29576691 TI - Structural reliability calculation method based on the dual neural network and direct integration method. AB - Structural reliability analysis under uncertainty is paid wide attention by engineers and scholars due to reflecting the structural characteristics and the bearing actual situation. The direct integration method, started from the definition of reliability theory, is easy to be understood, but there are still mathematics difficulties in the calculation of multiple integrals. Therefore, a dual neural network method is proposed for calculating multiple integrals in this paper. Dual neural network consists of two neural networks. The neural network A is used to learn the integrand function, and the neural network B is used to simulate the original function. According to the derivative relationships between the network output and the network input, the neural network B is derived from the neural network A. On this basis, the performance function of normalization is employed in the proposed method to overcome the difficulty of multiple integrations and to improve the accuracy for reliability calculations. The comparisons between the proposed method and Monte Carlo simulation method, Hasofer-Lind method, the mean value first-order second moment method have demonstrated that the proposed method is an efficient and accurate reliability method for structural reliability problems.

However, the extract of Psidium guajava leaf is not yet evaluated on changes of lipid profile in hepatic disease affected rats. Objective: The present study was aimed to evaluate the mitigation effect of the ethanolic extract of P. guajava leaf and its isolated quercetin fraction on hepatotoxic rats. Materials and Methods: Carbon tetrachloride (CCl4) was injected to rats for hepatic disease induction and silymarin drug was used as positive control to compare plant ethanolic extract. The lipid profiles were assessed in both plasma and liver tissue of diseased and control rats. Results: Levels of total cholesterol, triglycerides, free fatty acids, phospholipids, and low-density lipoprotein cholesterol were increased and the level of high-density lipoprotein cholesterol (HDL-C) was decreased in CCl4-induced hepatotoxic rats. The treatment of P. guajava (100, 200, and 300 mg/kg, bw) and isolated quercetin fraction (20 mg/kg, bw) doses decreased the elevated levels of all these parameters in diseased rats and restored the normal concentration of HDL-C. Conclusion: The results of the present study concluded that the P. guajava leaf and its isolated quercetin fraction can significantly regulate lipid metabolism in CCl4-induced hepatotoxic rats and decrease the disease rate.

PMID- 29576695 TI - Demethoxycurcumin, a Natural Derivative of Curcumin Abrogates Rotenone-induced Dopamine Depletion and Motor Deficits by Its Antioxidative and Anti-inflammatory Properties in Parkinsonian Rats. AB - Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder (NDD) associated with the loss of dopaminergic neurons in the substantia nigra and subsequently has an effect on motor function and coordination. The pathology of PD is multifactorial, in which neuroinflammation and oxidative damage are the two of the main protagonists. Objectives: The present study aims to assess the potential antioxidant and anti-inflammatory effects of demethoxycurcumin (DMC), a natural derivative of curcumin, against rotenone-induced PD in rats. Materials and Methods: Rats were randomized and divided into six groups: control, rotenone (0.5 mg/kg/day, intraperitoneal in sunflower oil) treated for 7 days, rotenone and DMC (5, 10, and 20 mg/kg b.w) cotreated, and DMC (20 mg/kg b.w) alone treated groups. Results: Based on the dopamine concentration and biochemical estimations, the effective dose of DMC was selected and the chronic study was performed. At the end of the experimental period, behavioral studies and protein expression patterns of inflammatory markers were analyzed. Rotenone treatment led to motor dysfunctions, neurochemical deficits, and oxidative stress and enhanced expressions of inflammatory markers, whereas oral administration of DMC attenuated all the above. Conclusion: Even though further research is needed to prove its efficacy in clinical trial, the results of our study showed that DMC may offer a promising and new therapeutic lead for the treatment of NDDs including PD.

AB - Background: "Decocting later" is important procedure for the extraction of herbal medicines containing volatile compounds. Objective: This study was performed to investigate optimal conditions for "Decocting later" of Menthae herba in Eungyo san (EGS) and correlation between extraction variables and the yields of d/l menthol, a marker compound of Menthae herba. Materials and Methods: The decocting temperature, total decocting time, and decocting later time were chosen as individual variables, and the yield of d/l-menthol was set as the response value which were calculated by using a Box-Behnken design (BBD). The amount of d/l menthol was quantified using gas chromatography/mass spectrometry. Results: Response surface methodology (RSM) was used to predict optimal conditions for decocting later of Menthae herba into the formula. Optimal conditions for "Decocting later" from RSM were as follows: 100.63 degrees C of decocting temperature; 82.95 min of total decocting time; 19.11 min of decocting later time. Both decocting temperature and total decocting time showed significant correlation with the yield of d/l-menthol.

AB - Background: Silybum marianum, a member of the Aster family, is a well-known Chinese herb and the source of a popular antioxidant that is extensively used in Asia. The abundant S. marianum straws are still underutilized and wastefully discarded to pollute the environment. Objective: To solve the above problem and better utilize S. marianum straws, the objective of this study was to optimize the conditions for extraction of silymarin from S. marianum straws. Materials and Methods: A combination of microwave-assisted extraction and response surface methodology (RSM) was used for silymarin from S. marianum straws and yield assessment by high-performance liquid chromatography method. The RSM was based on a five-level, four-variable central composite design (CCD).

PMID- 29576698 TI - Ameliorative Effect of Camel's Milk and Nigella Sativa Oil against Thioacetamide induced Hepatorenal Damage in Rats. AB - Background: Camel milk (CM) and Nigella sativa (NS) have been traditionally claimed to cure wide range of diseases and used as medicine in different part of world, particularly in Saudi Arabia. Several research studies have been published that proved beneficial effects of CM and NS. Objective: This study was undertaken to investigate the antihepatotxic potential of CM and NS oil (NSO) against thioacetamide (TAA)-induced hepato and nephrotoxicity in rats. Materials and Methods: Thirty female Albino Wistar rats were randomly divided in to six groups having five rats in each group. A single subcutaneous injection of TAA (100 mg/kg b. w.) was administered to all the rats in Group-II to VI on 1st day to induce hepatorenal damage. Group I served as a normal control while Group II served as toxic control for comparison purpose. Experimental animals in Group III, IV, and V were supplemented with fresh CM, (250 mL/24 h/cage), NSO (2 mL/kg/day p. o.), and NSO + fresh CM, respectively. Group VI was treated with a polyherbal hepatoprotective Unani medicine Jigreen (2 mL/kg/day p. o.) for 21 days. TAA induced hepatorenal damage and protective effects of CM and NSO were assessed by analyzing liver and kidney function tests in the serum. Histopathology of liver and kidney tissues was also carried out to corroborate the findings of biochemical investigation. Results: The results indicated that the TAA intoxicated rats showed significant increase in the alanine transaminase, aspartate transaminase, gamma-glutamyl transpeptidase, alkaline phosphatase, lipid profile, urea, creatinine, uric acid, sodium, and potassium levels in serum. Treatment of rats with CM, NSO, and CM plus NSO combination and Jigreen significantly reversed the damage and brought down the serum biochemical parameters and lipid profile toward the normal levels. The histopathological studies also support the hepato and nephroprotective effects of CM and NSO. Conclusion: This study demonstrated the ameliorative effects of CM, NSO, and CM plus NSO combination against TAA-induced hepatorenal toxicity in rats. SUMMARY: The antihepatotxic potential of Camel's Milk (CM) and Nigella sativa oil (NSO) against thioacetamide (TAA) induced hepatorenal toxicity was evaluated in ratsThe oral administration of fresh CM (250 mL/24h/cage), NSO (2 mL/kg/day) and NSO+fresh CM and Jigreen (2 mL/kg/day) for 21 days significantly decreased the hepatorenal toxicity as evidenced from analyzed biochemical parameters in serum and histopathological studies of liver and kidney tissuesThis study demonstrated the ameliorative effects of CM and NSO against TAA induced hepatorenal toxicity.

PMID- 29576699 TI - Modeling and Optimum Extraction of Multiple Bioactive Exopolysaccharide from an Endophytic Fungus of Crocus sativus L. AB - Background: Crocus sativus L. (saffron) is a scarce plant that has been used as food flavoring agent, coloring agent, and traditional herbal medicine. Methods: The bioactivity of exopolysaccharide (EPS) extracted from an endophytic fungus of C. sativus was examined for the first time by antioxidative, antitumor, and antibacterial assays. The extraction conditions for EPS were optimized by combining the response surface methodology with Box-Behnken design. Results: EPS exhibited excellent scavenging activities against 1,1-diphenyl-2-picrylhydrazyl, hydroxyl and superoxide anion radicals, and moderate cytotoxicities against K562, A549, HL-60, and HeLa cells. The optimum extraction conditions for EPS were as follows: precipitation time of 16 h, precipitation temperature of 3.7 degrees C, pH 7.2, and ratio of ethanol to fermented broth of 5:1 (L/L). Under the optimized conditions, the yield of EPS reached 162 +/- 6 MUg/L which was close to the predicted one (165 MUg/L). Moreover, high-performance liquid chromatography of monosaccharide composition showed that EPS comprised mannose, glucose, galactose xylose, and arabinose in a molar ratio of 25.6:16.5:1.0:3.8:5.4. Conclusion: EPS may be an eligible substitute for C. sativus and a potential bioactive source applicable to pharmaceutical and food industries.

PMID- 29576700 TI - Combined Antihypertensive Effect of Paeoniflorin Enriched Extract and Metoprolol in Spontaneously Hypertensive Rats. AB - Background: Hypertension is a great global health challenge and it mostly requires drug combination therapy with the various advantages. Metoprolol (MP) and paeoniflorin are both commonly used for the treatment of hypertension. However, whether they exert synergistic effects on antihypertension or not remains unclear, especially on vascular endothelial function. Objective: The purpose of the study is to investigate the advantages of the combined antihypertensive effects of paeoniflorin enriched extract from Radix Paeoniae Alba (RE) and MP in spontaneously hypertensive rats (SHR). Materials and Methods: SHR divided into six groups (n = 8 each group), animals in each group were administrated orally with distilled water, MP (6 and 20 mg/kg), RE (30 and 90 mg/kg), and MP (6 mg/kg) combined with RE (30 mg/kg) (MP + RE), respectively, daily for 6 weeks. Blood pressure (BP) and microcirculation were assessed. The organ bath experiment and hematoxylin and eosin staining were, respectively, performed for the functional and pathological vascular function analysis. Immunohistochemistry was applied to detect endothelial nitric oxide synthase (eNOS) expression in aorta, heart, and kidney. Further, high-performance liquid chromatography was employed to quantitatively determine paeoniflorin in RE and MP + RE sample solvent, as well as in plasma of Sprague-Dawley rats (SD) after single-dose administration of them. Results: The results showed that MP + RE significantly reduced BP, increased microcirculation, improved vascular function and pathological changes, and upregulated eNOS expression. MP was also found to increase the blood concentration of paeoniflorin in SD.

AB - Background: In traditional folk medicine, Limonium tetragonum is used in the treatment of uterine hemorrhage, tinnitus, and oligomenorrhea. Objective: This study aimed to identify the therapeutic effect of L. tetragonum EtOAc extract (EALT) on liver of mice with chronic alcohol poisoning. Materials and Methods: C57BL/6J mice were administered 100 mg/kg of EALT with a single binge ethanol/Lieber-DeCarli liquid diet for 8 weeks. Results: The chronic-binge ethanol diet induced a significant increase in liver marker enzyme activities. Coadministration of EALT reversed the elevation of serum total cholesterol and triglyceride as well as aspartate aminotransferase and alanine aminotransferase due to chronic alcohol consumption. Histologic findings including markedly attenuated fat accumulation in hepatocytes were observed in EALT-treated mice. EALT supplementation prevented alcoholic liver injury through attenuation of inflammatory mediators such as toll-like receptor-4, cytochrome P4502E1, and cyclooxygenase-2, and inflammatory cytokine interleukin-6. Conclusion: Results provided direct experimental evidence for the hepatoprotective effect of EALT in the NIAAA mouse model. Therapeutic attempts with the L. tetragonum extract might be useful in the management of alcoholic liver disease. SUMMARY: Halophyte Limonium tetragonum has recently been of interest in Korea for its nutritional value and salty taste which made it an ideal vegetablePhytochemical analysis of L. tetragonum EtOAc extract (EALT) resulted in nine compounds including catechins and myricetin glycosides as main componentsAdministration of EALT for 8 weeks showed hepatoprotective effect on Lieber-DeCarli diet-fed mouse modelA significant decrease in liver marker enzymes and inflammatory mediators was also detected.

AB - Background: Citri Reticulatae Pericarpium is the dried mature pericarp of Citrus reticulata Blanco which can be divided into "Chenpi" and "Guangchenpi." "Guangchenpi" is the genuine Chinese medicinal material in Xinhui, Guangdong province; based on the greatest quality and least amount, it is most expensive among others. Hesperidin is used as the marker to identify Citri Reticulatae Pericarpium described in the Chinese Pharmacopoeia 2010. However, both "Chenpi" and "Guangchenpi" contain hesperidin so that it is impossible to differentiate them by measuring hesperidin. Objective: Our study aims to develop an efficient and accurate method to separate and identify "Guangchenpi" from other Citri Reticulatae Pericarpium. Materials and Methods: The genomic deoxyribonucleic acid (DNA) of all the materials was extracted and then the internal transcribed spacer 2 was amplified, sequenced, aligned, and analyzed. The secondary structures were created in terms of the database and website established by Jorg Schultz et al. High-performance liquid chromatography-diode array detection-electrospray Ionization/mass spectrometry (HPLC-DAD-ESI-MS)/MS coupled with chemometric analysis was applied to compare the differences in chemical profiles of the three kinds of Citri Reticulatae Pericarpium. Results: A total of 22 samples were classified into three groups. The results of DNA barcoding were in accordance with principal component analysis and hierarchical cluster analysis. Eight compounds were deduced from HPLC-DAD-ESI-MS/MS. Conclusions: This method is a reliable and effective tool to differentiate the three Citri Reticulatae Pericarpium. SUMMARY: The internal transcribed spacer 2 regions and the secondary structure among three kinds of Citri Reticulatae Pericarpium varied considerablyAll the 22 samples were analyzed by high-performance liquid chromatography (HPLC) to obtain the chemical profilesPrincipal component analysis and hierarchical cluster analysis were used in the chemometric analysisdeoxyribonucleic acid barcoding and HPLC-diode array detection electrospray ionization/mass spectrometry/MS coupled with chemometric analysis provided an accurate and strong proof to identify these three herbs.

PMID- 29576705 TI - Antibacterial Activity of Azadirachta indica, Pongamia pinnata, Psidium guajava, and Mangifera indica and their mechanism of action against Streptococcus mutans. AB - Background: Curative plants have reportedly been used to make chewing sticks/toothbrushes intended for the treatment of oral diseases. Objective: The in vitro antibacterial activities of Azadirachta indica, Pongamia pinnata, Psidium guajava, and Mangifera indica were evaluated against Streptococcus mutans, along with the cytotoxicity and antioxidant and synergistic potentials. The effect of M. indica on the expression of crucial virulence genes spaP and gtfB of S. mutans was determined. Materials and Methods: The antibacterial activity was determined using a modified microdilution method. The antioxidant potential was evaluated using diphenyl picrylhydrazyl (DPPH), Griess reagent, and nitroblue tetrazolium calorimetric assays. The synergistic activity was investigated using a modified checkerboard method, while the cytotoxicity was determined according to a cell proliferation 2,3-Bis-(2-methoxy-4-nitro-5 sulfophenyl)-2H-tetrazolium-5-carboxanilide salt assay. Reverse transcription was the chosen method for determining the difference in expression of the spaP and gtfB genes after treatment with the plant sample. Results: M. indica and A. indica had the highest antibacterial activity at concentrations of 0.3 mg/ml and 6.25 mg/ml, respectively. A. indica had the best free radical scavenging of DPPH, exhibiting 50% inhibition at 28.72 MUg/ml; while M. indica showed better superoxide scavenging potential than the positive control quercetin. Both M. indica and A. indica had adequate activity against the nitric oxide-free radical (12.87 and 18.89 MUg/ml, respectively). M. indica selectively reduced the expression of the gtfB gene, indicating a mechanism involving Glucotranferases, specifically targeting bacterial attachment. SUMMARY: Mangifera indica and Azadirachta indica had very good antibacterial activity against Streptococcus mutans and moderate toxicity against Vero cellsM. indica had the best antioxidant capacity overallM. indica reduced the expression of gtfB gene at 0.5 mg/ml.

PMID- 29576706 TI - Rhynchophylline Downregulates Phosphorylated cAMP Response Element Binding Protein, Nuclear Receptor-related-1, and Brain-derived Neurotrophic Factor Expression in the Hippocampus of Ketamine-induced Conditioned Place Preference Rats. AB - Background: Addiction to ketamine is becoming a serious public health issues, for which there exists no effective treatment. Rhynchophylline (Rhy) is an alkaloid extracted from certain Uncaria species that is well known for both its potent anti-addictive and neuroprotective properties. Increasing evidence supports the contributions of cAMP response element binding protein (CREB), nuclear receptor related-1 (Nurr1), and brain-derived neurotrophic factor (BDNF) in modulating neural and behavioral plasticity which was induced by addictive drugs. Objective: To investigate the effects of Rhy on the behavior and the levels of phosphorylated CREB (p-CREB), Nurr1, and BDNF in the hippocampus of ketamine induced conditioned place preference (CPP) rats. Materials and Methods: CPP paradigm was used to establish the model of ketamine-dependent rats and to evaluate the effect of Rhy on ketamine dependence. The expressions of p-CREB, Nurr1, and BDNF were tested by Western blotting and immunohistochemistry. Results: We observed that Rhy can reverse the behavior preference induced by ketamine CPP training. At the same time, expression of p-CREB, Nurr1, and BDNF, which was significantly increased by ketamine, was restored in the Rhy -treated group. Conclusion: This study indicates that Rhy can reverse the reward effect induced by ketamine in rats and the mechanism can probably be related to regulate the hippocampal protein expression of p-CREB, Nurr1, and BDNF. SUMMARY: P-CREB, Nurr1 and BDNF play an important role in the formation of ketamine-induced place preference in ratsRhynchophylline reversed the expression of p-CREB, Nurr1 and BDNF which was activated by ketamine in the hippocampusRhynchophylline demonstrates the potential effect of mediates ketamine induced rewarding effect.

PMID- 29576708 TI - Further Study of Influence of Panax notoginseng on Intestinal Absorption Characteristics of Triptolide and Tripterine in Rats with Tripterygium wilfordii. AB - Background: Tripterygium wilfordii (TW) is widely employed to treat rheumatoid arthritis and autoimmune disorders clinically, which, however, accompany with disturbing hepatotoxicity and nephrotoxicity. The previous research showed that Panax notoginseng (PN) compatibly and significantly reduces the TW-induced hepatotoxicity. Objective: To explore the underlying mechanism, the present study was designed to reveal the influence of PN on the intestinal absorption process of TW-derived active components in rat. Materials and Methods: An in situ single pass intestinal perfusion technique was established and preformed to obtain the perfusate samples of triptolide (TP), tripterine (TE), TW extract, and TW-PN extract. A rapid and sensitive ultra-performance liquid-chromatography tandem mass spectrometry method was subsequently developed and validated to determine the concentrations of TP and TE in the perfusate samples. Then, the absorption parameters, effective permeability, absorption rate constant, and percentage of 10 cm intestinal absorption were calculated strictly. Results: The final data indicated that both TP and TE have no special absorption site in the intestine and are primarily absorbed in a passive manner. Otherwise, the absorption of TP was decreased from compatibility of PN, but the absorption of TE was enhanced. Conclusion: The absorption reduction of TP and absorption elevation of TE from TW initiated by the combination of PN are contributed to attenuate the toxicity and reinforce the therapeutic efficacy of TW. It is practically reasonable of usage of TW compatibility with PN clinically. SUMMARY: Panax notoginseng (PN) regulated the absorption process of Tripterygium wilfordii (TW) in intestineBoth triptolide (TP) and tripterine (TE), two typical components of TW, have no special absorption site in the intestine and are primarily absorbed in a passive mannerPN decreased the absorption of TP and enhanced the absorption of TE in the intestine.

PMID- 29576707 TI - Novel Method of Preparation and Activity Research on Arctigenin from Fructus Arctii. AB - Background: Arctigenin has many pharmacological activities with clinical significance and is derived from Arctium lappa L. However, the present extraction method is inefficient and does not have meaningful industrial production. Objective: A new method to directly prepare arctigenin was established by combining enzyme-assisted extraction and central composite design. Arctigenin's further pharmacological activity was also surveyed in vitro. Materials and Methods: beta-D-Glucosidase, a food-grade enzyme, was added directly to the fruits of A. lappa L. to hydrolyze the arctiin to arctigenin, and the obtained samples were subsequently subjected to ethanol (30%, v/v) extraction. The pharmacological activity of the extraction and arctigenin was determined by inhibiting acetylcholinesterase (AChE) and scavenging nitrite. Results: The factors investigated include the enzyme concentration (0.5%-2.5%), ultrasound time (10 min-3 0 min), and extraction temperature (30 degrees C-50 degrees C). From the analysis of the results by Design-Expert (V8.0.6), the optimal extraction conditions were obtained: enzyme concentration (1.4%), ultrasound time (25 min), and extraction temperature (45 degrees C). The highest yield of arctigenin, obtained under the optimal conditions was 6.39%, representing an increase of 28.15% compared to the reference extraction without enzyme processing. The IC50 values of the extraction and arctigenin, respectively, for inhibiting AChE were 0.572 mg/ml and 0.462 mg/ml, and those for nitrite scavenging were 34.571 mg/ml and 17.49 mg/ml. Conclusions: The results demonstrate that using an enzyme directly in the production is an effective means for extracting arctigenin from Fructus arctii. The extraction has the activities of inhibiting AChE and scavenging nitrite, probably because there has arctigenin in it. It is implied that the extraction and arctigenin could contribute to human health in clinical applications. SUMMARY: The new method of adding enzyme directly to the preparation of arctigenin was carried out instead of preparing arctigenin by two-step methodThree factors affecting the efficiency of preparation were analyzed and discussed include the enzyme concentration, ultrasound time, and extraction temperature by central composite designThis new method of preparing arctigenin improved the yield significantly than other methodsArctigenin has remarkable pharmacological activities of inhibiting acetylcholinesterase and scavenging nitrite.

PMID- 29576709 TI - Antioxidant and Hemolysis Protective Effects of Polyphenol-Rich Extract from Mulberry Fruits. AB - Background: Mulberry fruits are a superior source of polyphenol, especially anthocyanins that contribute potentially to the beneficial effects which include reducing the risk of cardiovascular diseases and cancers with antioxidant, anti inflammatory, and chemoprotective properties. Objectives: In this study, purification of the polyphenol-rich extract from mulberry fruit (MPE) was purified and assessed the activities of antioxidant and hemolysis protective in vivo and in vitro. Materials and Methods: Antioxidant activities in vitro was measured by quantifying its 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, reducing power and Fe2+-chelating ability. MPE was purified by high pressure liquid chromatography (HPLC) and analyzed individual polyphenols using liquid chromatography-mass spectrometry (LC-MS)/MS. Results: The total polyphenol content was 147.69 +/- 0.02 mg gallic acid equivalents (GAE)/g dried weight (DW) in the extract and 403.55 +/- 0.02 mg GAE/g DW in the purified extract. Further identification by HPLC-ultraviolet-visible and LC-MS/MS analysis indicated in MPE, an anthocyanin compound, cyanidin-3-O-glucoside. With regard to in vitro assays, MPE possessed antioxidant effect, especially in Fe2+ chelating ability with an IC50 value of 1.016 mg/mL. The protective effects on mouse red blood cell hemolysis and lipid peroxidation ex vivo were dose and time dependent. Conclusion: It indicates that MPE could be a good candidate for future biomedical applications to promote human health with limited side effects. SUMMARY: Mulberry fruit is an excellent source of polyphenols, in particular, anthocyanins, which has infinite health benefits. This study determined the predominant anthocyanin, cyanidin-3-glucoside, could possibly be the rationale behind the antioxidant and antihemolytic effect of MPE. Results indicate that MPE could be a good candidate for future biomedical applications to promote human health with limited side effects.

PMID- 29576710 TI - Capsaicin reverses the inhibitory effect of licochalcone A/beta-Arbutin on tyrosinase expression in b16 mouse melanoma cells. AB - Introduction: Melanin is synthesized by melanocytes, which are located in the basal layer of the skin. After synthesis, melanin is further deposited on the surface of the skin to form black spots or chloasma. Tyrosinase is a rate limiting enzyme that plays an important role in melanogenesis. Currently, there are many drugs that inhibit tyrosinase expression to further reduce melanogenesis. Nevertheless, some of these could reverse the pharmacological effect of other drugs, when used simultaneously. Materials and Methods: B16 mouse melanoma cells were treated with the tyrosinase inhibitors licochalcone A and beta-arbutin, alone or in combination with capsaicin, an alkaloid found in peppers. Cytotoxicity, melanin content, and tyrosinase activity and expression were determined. Results: Licochalcone A/beta-arbutin inhibited tyrosinase expression and further hindered melanin synthesis when applied individually to B16 mouse melanoma cells. However, licochalcone A/beta-arbutin combined with 50 MUmol/L capsaicin enhanced the expression of tyrosinase in these cells and further increased melanin content. Conclusion: Our data implied that capsaicin could reverse the inhibitory effect of licochalcone A/beta-arbutin on tyrosinase expression in B16 mouse melanoma cells. SUMMARY: B16 mouse melanoma cells were treated with the tyrosinase inhibitors licochalcone A and beta-arbutin, alone or in combination with capsaicin, an alkaloid found in peppers.

PMID- 29576711 TI - Cordyceps militaris Fraction induces apoptosis and G2/M Arrest via c-Jun N Terminal kinase signaling pathway in oral squamous carcinoma KB Cells. AB - Background: Cordyceps militaris fraction (CMF) has been shown to possess in vitro antitumor activity against human chronic myeloid leukemia K562 cells in our previous research. Materials and Methods: The in vitro inhibitory activities of CMF on the growth of KB cells were evaluated by viability assay. The apoptotic and cell cycle influences of CMF were detected by 4',6-diamidino-2-phenylindole staining and flow cytometry assay. The expression of different apoptosis associated proteins and cell cycle regulatory proteins was examined by Western blot assay. The nuclear localization of c-Jun was observed by fluorescence staining. Objective: The objective of this study was to investigate the antiproliferative effect of CMF as well as the mechanism underlying the apoptosis and cell cycle arrest it induces in KB cells. Results: CMF suppressed KB cells' proliferation in a dose- and time-dependent manner. Flow cytometric analysis indicated that CMF induced G2/M cell cycle arrest and apoptosis. Western blot analysis revealed that CMF induced caspase-3, caspase-9, and PARP cleavages, and increased the Bax/Bcl-2 ratio. CMF also led to increased expression of p21, decreased expression of cyclin B1, mitotic phosphatase cdc25c, and mitotic kinase cdc2, as well as unchanged expression of p53. In addition, CMF stimulated c-Jun N terminal kinases (JNK) protein phosphorylations, resulting in upregulated expression of c-Jun and nuclear localization of c-Jun. Pretreatment with JNK inhibitor SP600125 suppressed CMF-induced apoptosis and G2/M arrest. Conclusions: CMF is capable of modulating c-Jun caspase and Bcl-2 family proteins through JNK dependent apoptosis, which results in G2/M phase arrest in KB cells. CMF could be developed as a promising candidate for the new antitumor agents. SUMMARY: CMF exhibited strong anticancer activity against oral squamous carcinoma KB cellsCMF inhibited KB cells' proliferation via induction of apoptosis and G2/M cell cycle arrestCMF activated JNK signaling pathway and promoted the nuclear localization of c-JunCMF regulated the apoptosis- and cell cycle-related proteins in a manner dependent on JNK/c-Jun pathway.

PMID- 29576712 TI - Computational tool for immunotoxic assessment of pyrethroids toward adaptive immune cell receptors. AB - Background: Pyrethroids have prominently known for their insecticidal actions worldwide, but recent reports as anticancer and antiviral applications gained a lot of interest to further understand their safety and immunotoxicity. Objective: This encouraged us to carry out our present study to evaluate the interactions of pyrethroids toward adaptive immune cell receptors. Materials and Methods: Type 1 and Type 2 pyrethroids were tested on T (CD4 and CD8) and B (CD28 and CD45) immune cell receptors using Maestro 9.3 (Schrodinger, LLC, Cambridge, USA). In addition, top-ranked tested ligands were too explored for toxicity prediction in rodents using ProTOX tool. Results: Pyrethroids (specifically type 2) such as fenvalerate (-5.534 kcal/mol: CD8), fluvalinate (-4.644 and - 4.431 kcal/mol: CD4 and CD45), and cypermethrin (-3.535 kcal/mol: CD28) have outcome in less energy or more affinity for B-cell and T-cell immune receptors which may later result in the immunosuppressive and hypersensitivity reactions. Conclusion: The current findings have uncovered that there is a further need to assess the Type 2 pyrethroids with wet laboratory experiments to understand the chemical nature of pyrethroid-induced immunotoxicity. SUMMARY: Fenvalerate showed apex glide score toward CD8 immune receptor, while fluvalinate confirmed top-ranked binding with CD4 and CD45 immune proteinsIn addition, cypermethrin outcame in top glide score against CD28 immune receptorTop dock hits (Type 2) pyrethroids have shown probable toxicity targets toward AOFA: Amine oxidase (flavin-containing) A and PGH1: Prostaglandin G/H synthase 1, respectively.

AB - Aim: The aim of this study is to establish a method for determination of eupatilin in Folium artemisiae Argyi and observe the inhibitory effect of Folium artemisiae Argyi extract on human hepatoma SMMC-7721 cells. Methods: High performance liquid chromatograph system with 2910 pump, 2930 UV detector, and N2000 workstation was used for determination of eupatilin in Folium artemisiae Argyi. Human hepatoma SMMC-7721 cells were cultured and cell proliferation was measured using the MTT assay. The expression protein levels of p53, Topo II, and bcl-2 were detected using Western blotting. Results: Eupatilin exhibited a linearity range of 0.5-3.0 MUg/mL and a recovery of 100.72%, relevant standard derivation = 2.28%. Folium artemisiae Argyi extract had marked cytostatic and cytotoxic effects on SMMC-7721 cells, inhibited the SMMC-7721 colony formation in a dose-dependent manner. Folium artemisiae Argyi extract already possessed delayed effect after treating SMMC-7721 cells for 8 h, which became obvious at 12 h from treatment. After drug withdrawal, cells still tended to apoptosis. Folium artemisiae Argyi extract could inhibit p53, Topo II, and bcl-2 expressions in tumor cells. The present method for determination of eupatilin is simple, fast, accurate, sensitive, and reproducible. Conclusion: Hepatoma SMMC-7721 cells are quite sensitive to Folium artemisiae Argyi extract, which may be associated with its suppression of p53, Topo II, and bcl-2 expressions. SUMMARY: The study aimed to establish a method for determination of eupatilin in Folium artemisiae Argyi and observe the inhibitory effect of Folium artemisiae Argyi extract on human hepatoma SMMC-7721 cells.

PMID- 29576716 TI - Sparse signals recovered by non-convex penalty in quasi-linear systems. AB - The goal of compressed sensing is to reconstruct a sparse signal under a few linear measurements far less than the dimension of the ambient space of the signal. However, many real-life applications in physics and biomedical sciences carry some strongly nonlinear structures, and the linear model is no longer suitable. Compared with the compressed sensing under the linear circumstance, this nonlinear compressed sensing is much more difficult, in fact also NP-hard, combinatorial problem, because of the discrete and discontinuous nature of the [Formula: see text]-norm and the nonlinearity. In order to get a convenience for sparse signal recovery, we set the nonlinear models have a smooth quasi-linear nature in this paper, and study a non-convex fraction function [Formula: see text] in this quasi-linear compressed sensing. We propose an iterative fraction thresholding algorithm to solve the regularization problem [Formula: see text] for all [Formula: see text]. With the change of parameter [Formula: see text], our algorithm could get a promising result, which is one of the advantages for our algorithm compared with some state-of-art algorithms. Numerical experiments show that our method performs much better than some state-of-the-art methods.

AB - Background: Rhubarb is a traditional Chinese medicine for treating traumatic brain injury (TBI). Purpose: The purpose of this study is to elucidate the potential mechanism of rhubarb by suppressing extracellular signal-regulated kinase (ERK) to ameliorate brain edema. Materials and Methods: Sprague-Dawley rats were separated into four groups at random. One group received 3 g/kg rhubarb, and another group received 12 g/kg rhubarb, and the vehicle group and sham group were administered the same dose of saline solution. The blood-brain barrier disruption and edema were detected by Evans blue extravasation and water content, respectively. ERK, Matrix metalloproteinase 9 (MMP-9), and zonula occluden-1 (ZO-1) in the damaged tissue were measured by western blot analysis and quantitative real-time polymerase chain reaction. Results: Rhubarb attenuated the brain edema after TBI, especially at the dose of 12 g/kg. Rhubarb significantly suppressed ERK, down-regulated MMP-9, and up-regulated ZO-1. Rhubarb might be a prospective therapeutic regimen to decrease edema in TBI. Conclusions: Rhubarb alleviates the edema by restraining the ERK signaling pathway. Our results contribute to the validation of the traditional use of rhubarb in the treatment of TBI and its mechanism. SUMMARY: The aim of this study was to explore the potential mechanism of rhubarb by suppressing extracellular signal-regulated kinase to ameliorate brain edema. Results: Rhubarb ameliorates edema caused by traumatic brain injury by inhibiting the ERK/Matrix metalloproteinase 9/zonula occluden-1 signaling pathway.

AB - The Schwarz algorithm for a class of elliptic quasi-variational inequalities with nonlinear source terms is studied in this work. The authors prove a new error estimate in uniform norm, making use of a stability property of the discrete solution. The domain is split into two sub-domains with overlapping non-matching grids. This approach combines the geometrical convergence of solutions and the uniform convergence of variational inequalities. PMID- 29576718 TI - Approximation properties of lambda-Bernstein operators.

AB - Synthesis, characterization, and investigation of antiproliferative activities against human cancer cell lines (MV4-11, MCF-7, and A549) and Toxoplasma gondii parasite of twelve novel 2,4-diaminotriazine-thiazoles are presented. The toxicity of the compounds was studied at three different cell types, normal mouse fibroblast (Balb/3T3), mouse fibroblast (L929), and human VERO cells. The structures of novel compounds were determined using 1H and 13C NMR, FAB(+)-MS, and elemental analyses. Among the derivatives, 4a-k showed very high activity against MV4-11 cell line with IC50 values between 1.13 and 3.21 ug/ml. Additionally, the cytotoxic activity of compounds 4a-k against normal mouse fibroblast Balb/3T3 cells is about 20-100 times lower than against cancer cell lines. According to our results, compounds 4a, 4b, 4d, and 4i have very strong activity against human breast carcinoma MCF-7, with IC50 values from 3.18 to 4.28 ug/ml. Moreover, diaminotriazines 4a-l showed significant anti-Toxoplasma gondii activity, with IC50 values 9-68 times lower than those observed for sulfadiazine. Molecular docking studies indicated DNA-binding site of hTopoI and hTopoII as possible anticancer targets and purine nucleoside phosphorylase as possible anti toxoplasmosis target. Our UV-Vis spectroscopic results indicate also that diaminotriazine-thiazoles tends to interact with DNA by intercalation. Additionally, the structure and the interaction and binding energies of a model complex formed by compound 4a and two thymine molecules are investigated using quantum mechanical methods.

AB - The Program for the Evaluation of the Enrichment of Relational Skills (PEERS), a social skills intervention for high functioning adolescents with autism spectrum disorder (ASD), has been proven efficacious in randomized control trials. However, the effectiveness of the PEERS program in community settings has not been studied. The present small-scale pilot study examined the effectiveness of the PEERS program in a community setting. Five adolescents and their caregivers participated in the PEERS intervention. Results indicated that the adolescents showed significant improvement in their social engagement, social cognition, social communication, social motivation, and knowledge of PEERS skills and concepts from pre- to post-intervention. Furthermore, adolescents showed significant reductions in their internalizing and autistic symptoms from pre- to post-intervention. The findings from this small-scale pilot study support the effectiveness of the PEERS program in community-based settings. PMID- 29576721 TI - Comparative molecular field analysis and molecular dynamics studies of the dopamine D2 receptor antagonists without a protonatable nitrogen atom. AB - The dopaminergic hypothesis of schizophrenia is the main concept explaining the direct reasons of schizophrenia and the effectiveness of current antipsychotics. All antipsychotics present on the market are potent dopamine D2 receptor antagonists or partial agonists. In this work we investigate a series of dopamine D2 receptor antagonists which do not fulfill the criteria of the classical pharmacophore model as they do not possess a protonatable nitrogen atom necessary to interact with the conserved Asp(3.32). Such compounds are interesting, inter alia, due to possible better pharmacokinetic profile when compared to basic, ionizable molecules. By means of homology modeling, molecular docking and molecular dynamics we determined that the compounds investigated interact with Asp(3.32) via their amide nitrogen atom. It was found that the studied compounds stabilize the receptor inactive conformation through the effect on the ionic lock, which is typical for GPCR antagonists. We constructed a CoMFA model for the studied compounds with the following statistics: R2 = 0.95, Q2 = 0.63. The quality of the CoMFA model was confirmed by high value of R2 of the test set, equal 0.96. The CoMFA model indicated two regions where bulky substituents are favored and two regions where bulky substituents are not beneficial. Two red contour regions near carbonyl groups were identified meaning that negative charge would be favored here. Furthermore, the S-oxide group is connected with blue contour region meaning that positive charge is favored in this position. These findings may be applied for further optimization of the studied compound series. PMID- 29576724 TI - Internationalized at work and localistic at home: The 'split' Europeanization behind Brexit. AB - This paper looks at the results of the referendum on the United Kingdom membership to the European Union in order to test the link between the internationalization of the local economy and the openness of the local society as factors associated with the Leave vote (Brexit). The paper compares a number of alternative explanations put forward in the public debate after the referendum. The empirical analysis suggests that the outcome of the referendum can be linked to an increasing tension between the ever increasing internationalization of local firms and the 'localistic' attitude of their employees. Brexit can be seen as the result of a process of 'split Europeanization' whereby Euroscepticism is triggered by the increasing mismatch between internationalized economies (and corporate economic interests) and localistic societies (and workers' attitudes and cultural preferences). PMID- 29576725 TI - Are There Gender Differences in Emotion Comprehension? Analysis of the Test of Emotion Comprehension. AB - This article examines whether there are gender differences in understanding the emotions evaluated by the Test of Emotion Comprehension (TEC). The TEC provides a global index of emotion comprehension in children 3-11 years of age, which is the sum of the nine components that constitute emotion comprehension: (1) recognition of facial expressions, (2) understanding of external causes of emotions, (3) understanding of desire-based emotions, (4) understanding of belief-based emotions, (5) understanding of the influence of a reminder on present emotional states, (6) understanding of the possibility to regulate emotional states, (7) understanding of the possibility of hiding emotional states, (8) understanding of mixed emotions, and (9) understanding of moral emotions. We used the answers to the TEC given by 172 English girls and 181 boys from 3 to 8 years of age. First, the nine components into which the TEC is subdivided were analysed for differential item functioning (DIF), taking gender as the grouping variable. To evaluate DIF, the Mantel-Haenszel method and logistic regression analysis were used applying the Educational Testing Service DIF classification criteria. The results show that the TEC did not display gender DIF. Second, when absence of DIF had been corroborated, it was analysed for differences between boys and girls in the total TEC score and its components controlling for age. Our data are compatible with the hypothesis of independence between gender and level of comprehension in 8 of the 9 components of the TEC. Several hypotheses are discussed that could explain the differences found between boys and girls in the belief component. Given that the Belief component is basically a false belief task, the differences found seem to support findings in the literature indicating that girls perform better on this task. PMID- 29576726 TI - Evaluation of a Train-The-Trainers Model for Family Peer Advocates in Children's Mental Health. AB - Standardized training and credentialing is increasingly important to states and healthcare systems. Workforce shortages in children's mental health can be addressed through training and credentialing of professional peer parents (called family peer advocates or FPAs), who deliver a range of services to caregivers. A theory-based training program for FPAs targeting skills and knowledge about childhood mental health services (Parent Empowerment Program, or PEP) was developed through a partnership among a statewide family-run organization, state policy leaders, and academic researchers. Prior studies by this team using highly experienced family peer advocates (who were also co-developers of the training program) as trainers found improvements in knowledge about mental health services and self-efficacy. In 2010, to meet demands and scale the model, a training of trainers (TOT) model was developed to build a cohort of locally-trained FPAs to deliver PEP training. A pre/post design was used to evaluate the impact of TOT model on knowledge and self-efficacy among 318 FPAs across the state. Participants showed significant pre-post (6 month) changes in knowledge about mental health services and self-efficacy. There were no significant associations between any FPA demographic characteristics and their knowledge or self-efficacy scores. A theory-based training model for professional peer parents working in the children's mental health system can be taught to local FPAs, and it improves knowledge about the mental health system and self-efficacy. Studies that evaluate the effectiveness of different training modalities are critical to ensure that high-quality trainings are maintained. PMID- 29576727 TI - Similarities and Differences in the Psychosocial Development of Children Placed in Different 24-h Settings. AB - Similarities and differences in the (short-term) psychosocial development of children in foster care, family-style group care, and residential care were investigated in a sample of 121 Dutch children (M age = 8.78 years; SD = 2.34 years; 47% female; 59% Caucasian) one year after their initial placement. Pretest and posttest measurements were carried out at the substitute caregivers using the CBCL. The results were examined at group level and case level. At group level, the findings showed no evidence for higher effectiveness in favor to the family oriented settings (foster care, and family-style group care), as hypothesized. By contrast, some small differences were found between foster care and family-style group care, in favor of the latter. At individual level, a more or less equal number of children (18%) with a clinical pretest score on psychosocial functioning clinically significant improved (behavioral normalization). An important concern is that a number of children without clinical psychosocial problems at the time of admission clinically significant deteriorated (behavioral aberration) in psychosocial functioning (20%). This might indicate a poor match between the risks, needs and responsivity of the child on the one hand and the chosen intervention on the other. Future research on factors that (prior and during placement) positively as well as negatively affect the child's psychosocial development is needed to further clarify this finding. PMID- 29576728 TI - Psychosocial Needs of Children in Foster Care and the Impact of Sexual Abuse. AB - Children in family foster care, especially those who have experienced sexual abuse, require a safe and nurturing environment in which their psychosocial needs are met. However, there is limited knowledge on how youth prioritize various needs and what impact previous experiences have on these needs. In this study, we asked youth (formerly) in family foster care to indicate their psychosocial needs, and analyzed if youth with a history of sexual abuse have different needs. A Q methodological study was conducted with 44 youth (age 16-28). Fifteen of them reported sexual abuse during their childhood. Using by-person factor analyses, respondents who share similar subjective views were grouped together. Qualitative interpretations of the factors show differences and similarities between and within the two groups, related to help from others, being independent, processing the past, and working toward the future. Although the needs of youth with and without experiences of sexual abuse seem mostly similar, one group of sexually abused youth specifically indicated not wanting an emotional connection to foster parents, but instead a strictly instrumental, professional relationship. This study captured the diverse perspectives of youth themselves, revealing that children in foster care differ with regard to what they consider as (most) important safety, belonging, self-esteem and self-actualization needs. PMID- 29576729 TI - Likelihood-based confidence intervals for a parameter with an upper or lower bound. AB - The precision of estimates in many statistical models can be expressed by a confidence interval (CI). CIs based on standard errors (SE) are common in practice, but likelihood-based CIs are worth consideration. In comparison to SEs, likelihood-based CIs are typically more difficult to estimate, but are more robust to model (re)parameterization. In latent variable models, some parameters may take on values outside of their interpretable range. Therefore, it is desirable to place a bound to keep the parameter interpretable. For likelihood based CI, a correction is needed when a parameter is bounded. The correction is known (Wu & Neale, 2012), but is difficult to implement in practice. A novel automatic implementation that is simple for an applied researcher to use is introduced. A simulation study demonstrates the accuracy of the correction using a latent growth curve model and the method is illustrated with a multilevel confirmatory factor analysis. PMID- 29576730 TI - Developing a Multi-Dimensional Early Elementary Mathematics Screener and Diagnostic Tool: The Primary Mathematics Assessment. AB - There is a critical need to identify primary level students experiencing difficulties in mathematics to provide immediate and targeted instruction that remediates their deficits. However, most early math screening instruments focus only on the concept of number, resulting in inadequate and incomplete information for teachers to design intervention efforts. We propose a mathematics assessment that screens and provides diagnostic information in six domains that are important to building a strong foundation in mathematics. This article describes the conceptual framework and psychometric qualities of a web-based assessment tool, the Primary Math Assessment (PMA). The PMA includes a screener to identify students at risk for poor math outcomes and a diagnostic tool to provide a more in-depth profile of children's specific strengths and weaknesses in mathematics. The PMA allows teachers and school personnel to make better instructional decisions by providing more targeted analyses. PMID- 29576732 TI - HIV-related sexual decisions made by African-American adolescents living in different family structures: study from an ecodevelopmental perspective. AB - Purpose: The purpose of this study was to explore the association between the dynamics of family structure and sexual behaviors of African-American adolescents using the ecodevelopmental theory. Methods: This study stratified data from 1,617 African-American adolescents of the Add Health Wave I respondents with an identified family composition. It examined the associations between family structure, parenting function, and adolescents' sexual decision-making: age of first sexual intercourse, sexual initiation before age 16, and using a condom during the first and last sexual intercourse. Results: Emotional connection between parents and children (feeling more love from the father: beta=0.17, P=0.0312; feeling more love from the mother: beta=0.3314, P=0.0420) and mothers' less permissive attitude toward adolescents' sexual experience in their teens (beta=0.33, P=0.0466) are positively associated with late age of sexual initiation of adolescents living in two-parent households. School-level factors (beta=0.07, P=0.0008) and the adolescents' characteristics (being older: 0.42, P=0.0002; heterosexuality: beta=2.28, P=0.0091) are the factors most positively related to the age of sexual initiation for those living with a single parent. Immediate social determinants, other than family factors (such as land use of immediate area [rural]: beta=9.84, P<0.0001; the condition of living unit: beta=1.55, P=0.0011; and safety of neighborhood: beta=4.46, P=0.004), are related to late age of sexual initiation among those living with other relatives/alone. A higher tendency of condom use consistency was present in adolescents living with two parents compared to those living in other family structures. Conclusion: Less parent/child connection and parent/family influence were found in African American adolescents living with other relatives or alone, suggesting that living with two residential parents plays an essential role in their late sexual initiation and could account for an important element to combat high HIV incidence of African-American adolescents. PMID- 29576731 TI - Aggressiveness, violence, homicidality, homicide, and Lyme disease. AB - Background: No study has previously analyzed aggressiveness, homicide, and Lyme disease (LD). Materials and methods: Retrospective LD chart reviews analyzed aggressiveness, compared 50 homicidal with 50 non-homicidal patients, and analyzed homicides. Results: Most aggression with LD was impulsive, sometimes provoked by intrusive symptoms, sensory stimulation or frustration and was invariably bizarre and senseless. About 9.6% of LD patients were homicidal with the average diagnosis delay of 9 years. Postinfection findings associated with homicidality that separated from the non-homicidal group within the 95% confidence interval included suicidality, sudden abrupt mood swings, explosive anger, paranoia, anhedonia, hypervigilance, exaggerated startle, disinhibition, nightmares, depersonalization, intrusive aggressive images, dissociative episodes, derealization, intrusive sexual images, marital/family problems, legal problems, substance abuse, depression, panic disorder, memory impairments, neuropathy, cranial nerve symptoms, and decreased libido. Seven LD homicides included predatory aggression, poor impulse control, and psychosis. Some patients have selective hyperacusis to mouth sounds, which I propose may be the result of brain dysfunction causing a disinhibition of a primitive fear of oral predation. Conclusion: LD and the immune, biochemical, neurotransmitter, and the neural circuit reactions to it can cause impairments associated with violence. Many LD patients have no aggressiveness tendencies or only mild degrees of low frustration tolerance and irritability and pose no danger; however, a lesser number experience explosive anger, a lesser number experience homicidal thoughts and impulses, and much lesser number commit homicides. Since such large numbers are affected by LD, this small percent can be highly significant. Much of the violence associated with LD can be avoided with better prevention, diagnosis, and treatment of LD. PMID- 29576733 TI - Spotlight on daytime napping during early childhood. AB - Daytime napping undergoes a remarkable change in early childhood, and research regarding its relationship to cognitive development has recently accelerated. In this review, we summarize our current understanding of this relationship focusing on children aged <5 years. First, we evaluate different studies on the basis of the experimental design used and the specific cognitive processes they investigate. Second, we analyze how the napping status of children may modulate the relationship between learning and napping. Third, the possible role of sleep spindles, ie, specific electroencephalographic components during sleep, in cognitive development is explored. We conclude that daytime napping is crucial in early memory development. PMID- 29576734 TI - Impact of preferential sampling on exposure prediction and health effect inference in the context of air pollution epidemiology. AB - Preferential sampling has been defined in the context of geostatistical modeling as the dependence between the sampling locations and the process that describes the spatial structure of the data. It can occur when networks are designed to find high values. For example, in networks based on the U.S. Clean Air Act monitors are sited to determine whether air quality standards are exceeded. We study the impact of the design of monitor networks in the context of air pollution epidemiology studies. The effect of preferential sampling has been illustrated in the literature by highlighting its impact on spatial predictions. In this paper, we use these predictions as input in a second stage analysis, and we assess how they affect health effect inference. Our work is motivated by data from two United States regulatory networks and health data from the Multi-Ethnic Study of Atherosclerosis and Air Pollution. The two networks were designed to monitor air pollution in urban and rural areas respectively, and we found that the health analysis results based on the two networks can lead to different scientific conclusions. We use preferential sampling to gain insight into these differences. We designed a simulation study, and found that the validity and reliability of the health effect estimate can be greatly affected by how we sample the monitor locations. To better understand its effect on second stage inference, we identify two components of preferential sampling that shed light on how preferential sampling alters the properties of the health effect estimate. PMID- 29576735 TI - Functional inverted Wishart for Bayesian multivariate spatial modeling with application to regional climatology model data. AB - Modern environmental and climatological studies produce multiple outcomes at high spatial resolutions. Multivariate spatial modeling is an established means to quantify cross-correlation among outcomes. However, existing models typically suffer from poor computational efficiency and lack the flexibility to simultaneously estimate auto- and cross-covariance structures. In this article, we undertake a novel construction of covariance by utilizing spectral convolution and by imposing an inverted Wishart prior on the cross-correlation structure. The cross-correlation structure with this functional inverted Wishart prior flexibly accommodates not only positive but also weak or negative associations among outcomes while preserving spatial resolution. Furthermore, the proposed model is computationally efficient and produces easily interpretable results, including the individual autocovariances and full cross-correlation matrices, as well as a partial cross-correlation matrix reflecting the outcome correlation after excluding the effects caused by spatial convolution. The model is examined using simulated data sets under different scenarios. It is also applied to the data from the North American Regional Climate Change Assessment Program, examining long-term associations between surface outcomes for air temperature, pressure, humidity, and radiation, on the land area of the North American West Coast. Results and predictive performance are compared with findings from approaches using convolution only or coregionalization. PMID- 29576736 TI - Testing for Marginal Linear Effects in Quantile Regression. AB - This paper develops a new marginal testing procedure to detect the presence of significant predictors associated with the conditional quantiles of a scalar response. The idea is to fit the marginal quantile regression on each predictor one at a time, and then base the test on the t-statistics associated with the most predictive predictors. A resampling method is devised to calibrate this test statistic, which has non-regular limiting behavior due to the selection of the most predictive variables. Asymptotic validity of the procedure is established in a general quantile regression setting in which the marginal quantile regression models can be misspecified. Even though a fixed dimension is assumed to derive the asymptotic results, the proposed test is applicable and computationally feasible for large-dimensional predictors. The method is more flexible than existing marginal screening test methods based on mean regression, and has the added advantage of being robust against outliers in the response. The approach is illustrated using an application to an HIV drug resistance dataset. PMID- 29576737 TI - Subnanogram proteomics: impact of LC column selection, MS instrumentation and data analysis strategy on proteome coverage for trace samples. AB - One of the greatest challenges for mass spectrometry (MS)-based proteomics is the limited ability to analyze small samples. Here we investigate the relative contributions of liquid chromatography (LC), MS instrumentation and data analysis methods with the aim of improving proteome coverage for sample sizes ranging from 0.5 ng to 50 ng. We show that the LC separations utilizing 30-MUm-i.d. columns increase signal intensity by >3-fold relative to those using 75-MUm-i.d. columns, leading to 32% increase in peptide identifications. The Orbitrap Fusion Lumos MS significantly boosted both sensitivity and sequencing speed relative to earlier generation Orbitraps (e.g., LTQ-Orbitrap), leading to a ~3-fold increase in peptide identifications and 1.7-fold increase in identified protein groups for 2 ng tryptic digests of the bacterium S. oneidensis. The Match Between Runs algorithm of open-source MaxQuant software further increased proteome coverage by ~ 95% for 0.5 ng samples and by ~42% for 2 ng samples. Using the best combination of the above variables, we were able to identify >3,000 proteins from 10 ng tryptic digests from both HeLa and THP-1 mammalian cell lines. We also identified >950 proteins from subnanogram archaeal/bacterial cocultures. The present ultrasensitive LC-MS platform achieves a level of proteome coverage not previously realized for ultra-small sample loadings, and is expected to facilitate the analysis of subnanogram samples, including single mammalian cells. PMID- 29576738 TI - Functionalized TiO2 nanoparticles labelled with 225Ac for targeted alpha radionuclide therapy. AB - The 225Ac radioisotope exhibits very attractive nuclear properties for application in radionuclide therapy. Unfortunately, the major challenge for radioconjugates labelled with 225Ac is that traditional chelating moieties are unable to sequester the radioactive daughters in the bioconjugate which is critical to minimize toxicity to healthy, non-targeted tissues. In the present work, we propose to apply TiO2 nanoparticles (NPs) as carrier for 225Ac and its decay products. The surface of TiO2 nanoparticles with 25 nm diameter was modified with Substance P (5-11), a peptide fragment which targets NK1 receptors on the glioma cells, through the silan-PEG-NHS linker. Nanoparticles functionalized with Substance P (5-11) were synthesized with high yield in a two step procedure, and the products were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and thermogravimetric analysis (TGA). The obtained results show that one TiO2-bioconjugate nanoparticle contains in average 80 peptide molecules on its surface. The synthesized TiO2-PEG-SP(5-11) conjugates were labelled with 225Ac by ion-exchange reaction on hydroxyl (OH) functional groups on the TiO2 surface. The labelled bioconjugates almost quantitatively retain 225Ac in phosphate-buffered saline (PBS), physiological salt and cerebrospinal fluid (CSF) for up to 10 days. The leaching of 221Fr, a first decay daughter of 225Ac, in an amount of 30% was observed only in CSF after 10 days. The synthesized 225Ac-TiO2-PEG-SP(5-11) has shown high cytotoxic effect in vitro in T98G glioma cells; therefore, it is a promising new radioconjugate for targeted radionuclide therapy of brain tumours. PMID- 29576739 TI - Tests of chameleon gravity. AB - Theories of modified gravity, where light scalars with non-trivial self interactions and non-minimal couplings to matter-chameleon and symmetron theories dynamically suppress deviations from general relativity in the solar system. On other scales, the environmental nature of the screening means that such scalars may be relevant. The highly-nonlinear nature of screening mechanisms means that they evade classical fifth-force searches, and there has been an intense effort towards designing new and novel tests to probe them, both in the laboratory and using astrophysical objects, and by reinterpreting existing datasets. The results of these searches are often presented using different parametrizations, which can make it difficult to compare constraints coming from different probes. The purpose of this review is to summarize the present state-of-the-art searches for screened scalars coupled to matter, and to translate the current bounds into a single parametrization to survey the state of the models. Presently, commonly studied chameleon models are well-constrained but less commonly studied models have large regions of parameter space that are still viable. Symmetron models are constrained well by astrophysical and laboratory tests, but there is a desert separating the two scales where the model is unconstrained. The coupling of chameleons to photons is tightly constrained but the symmetron coupling has yet to be explored. We also summarize the current bounds on f(R) models that exhibit the chameleon mechanism (Hu and Sawicki models). The simplest of these are well constrained by astrophysical probes, but there are currently few reported bounds for theories with higher powers of R. The review ends by discussing the future prospects for constraining screened modified gravity models further using upcoming and planned experiments.

Here we demonstrate the difficulties, which arise in doing so and report development of a process for derivation of free-glucaric acid from its Ca2+/K+ glucarate salts, which are both commercially available. Employing Amberlyst-15 (H+) exchange resin and azeotrope drying, powdered glucaric acid is prepared at > 99.96 % purity in 98.7 % dry yield. PMID- 29576741 TI - f(R) gravity modifications: from the action to the data. AB - It is a very well established matter nowadays that many modified gravity models can offer a sound alternative to General Relativity for the description of the accelerated expansion of the universe. But it is also equally well known that no clear and sharp discrimination between any alternative theory and the classical one has been found so far. In this work, we attempt at formulating a different approach starting from the general class of f(R) theories as test probes: we try to reformulate f(R) Lagrangian terms as explicit functions of the redshift, i.e., as f(z). In this context, the f(R) setting to the consensus cosmological model, the [Formula: see text]CDM model, can be written as a polynomial including just a constant and a third-order term. Starting from this result, we propose various different polynomial parameterizations f(z), including new terms which would allow for deviations from [Formula: see text]CDM, and we thoroughly compare them with observational data. While on the one hand we have found no statistically preference for our proposals (even if some of them are as good as [Formula: see text]CDM by using Bayesian Evidence comparison), we think that our novel approach could provide a different perspective for the development of new and observationally reliable alternative models of gravity. PMID- 29576742 TI - High life expectancy and reversed socioeconomic gradients of elderly people in Mexico and Costa Rica. AB - Background: Some existing estimates suggest, controversially, that life expectancy at age 60 (LE60) of Latin American males is exceptionally high. Knowledge of adult mortality in Latin America is often based on unreliable statistics or indirect demographic methods. Objectives: This study aimed to gather direct estimates of mortality at older ages in two Latin American countries (Mexico and Costa Rica) using recent longitudinal surveys and to determine the socioeconomic status (SES) gradients for LE60. Methods: Data were collected from independent panels of approximately 7,000 older adults followed over more than a decade-the MHAS and CRELES surveys. The age-specific death rates were modeled with Gompertz regression, and thousands of life tables were simulated to estimate LE60 and its confidence interval. Results: LE60 estimates obtained from MHAS and CRELES are similar to those obtained from traditional statistics, confirming the exceptionally high LE60 of men in the two countries. The expected gradients of higher LE60 with higher SES are not present, especially among males, who even show reverse gradients (some exaggerated by data issues). Conclusions: Vital statistics correctly estimate elderly mortality in Mexico and Costa Rica. The higher-than-expected LE60 among Latin American males in general, and particularly among low-SES individuals, seems to be real; their determinants should be thoroughly investigated. Contribution: This study shows with hard, reliable data, independent of traditional statistics, that elderly males in tropical Latin America enjoy an exceptionally high life expectancy and that SES gradients are absent or even reverse.

AB - Several studies suggest that curcumin and related compounds possess antioxidant and anti-inflammatory properties including modulation of lipopolysaccharide- (LPS ) mediated signalling in macrophage cell models. We here investigated the effects of curcumin and the two structurally unrelated analogues GG6 and GG9 in primary human blood-derived macrophages as well as the signalling pathways involved. Macrophages differentiated from peripheral blood monocytes for 7 days were activated with LPS or selective Toll-like receptor agonists for 24 h. The effects of test compounds on cytokine production and immunophenotypes evaluated as CD80+/CCR2+ and CD206+/CD163+ subsets were examined by ELISA and flow cytometry. Signalling pathways were probed by Western blot. Curcumin (2.5-10 MUM) failed to suppress LPS-induced inflammatory responses. While GG6 reduced LPS-induced IkappaB-alpha degradation and showed a trend towards reduced interleukin-1beta release, GG9 prevented the increase in proinflammatory CD80+ macrophage subset, downregulation of the anti-inflammatory CD206+/CD163+ subset, increase in p38 phosphorylation, and increase in cell-bound and secreted interleukin-1beta stimulated by LPS, at least in part through signalling pathways not involving Toll-like receptor 4 and nuclear factor-kappaB. Thus, the curcumin analogue GG9 attenuated the LPS-induced inflammatory response in human blood-derived macrophages and may therefore represent an attractive chemical template for macrophage pharmacological targeting.

AB - The PB1-F2 protein of influenza A virus has been considered a virulence factor, but its function in inducing apoptosis may be of disadvantage to viral replication. Host mechanisms to regulate PB1-F2-induced apoptosis remain unknown. We generated a PB1-F2-deficient avian influenza virus (AIV) H9N2 and found that the mutant virus replicated less efficiently in human lung epithelial cells. The PB1-F2-deficient virus produced less apoptotic cells, indicating that PB1-F2 of the H9N2 virus promotes apoptosis, occurring at the early stage of infection, in the lung epithelial cells. To understand how host cells regulate PB1-F2-induced apoptosis, we explored to identify cellular proteins interacting with PB1-F2 and found that HCLS1-associated protein X-1 (HAX-1), located mainly in the mitochondria as an apoptotic inhibitor, interacted with PB1-F2. Increased procaspase-9 activations, induced by PB1-F2, could be suppressed by HAX-1. In HAX 1 knockdown A549 cells, the replication of AIV H9N2 was suppressed in parallel to the activation of caspase-3 activation, which increased at the early stage of infection. We hypothesize that HAX-1 promotes AIV replication by interacting with PB1-F2, resulting in the suppression of apoptosis, prolonged cell survival, and enhancement of viral replication. Our data suggest that HAX-1 may be a promoting factor for AIV H9N2 replication through desensitizing PB1-F2 from its apoptotic induction in human lung epithelial cells.

AB - The "long-life elixir" has long represented for humans a dream, a vanity's sin for remaining young and to long survive. Today, because of ageing population phenomenon, the research of antiageing interventions appears to be more important than ever, for preserving health in old age and retarding/or delaying the onset of age-related diseases. A hope is given by experimental data, which evidence the possibility of retarding ageing in animal models. In addition, it has been also demonstrated in animal life-extending studies not only the possibility of increasing longevity but also the ability to retard the onset of age-related diseases. Interestingly, this recent evidence is leading to promise of obtaining the same effects in humans and resulting in benefits for their health in old ages. In order to achieve this goal, different approaches have been used ranging from pharmacological targeting of ageing, basic biological assays, and big data analysis to the recent use of young blood, stem cells, cellular, genetic, and epigenetic reprogramming, or other techniques of regenerative medicine. However, only a little fraction of these approaches has the features for being tested in clinical applications. Here, new emerging molecules, drugs, and procedures will be described, by evidencing potential benefits and limitations. PMID- 29576746 TI - Asymmetric Dimethyl Arginine as a Biomarker of Atherosclerosis in Rheumatoid Arthritis. AB - Cardiovascular disease is the main cause of morbidity and mortality in rheumatoid arthritis (RA). Despite the advent on new drugs targeting the articular manifestations, the burden of cardiovascular disease is still an unmet need in the management of RA. The pathophysiology of accelerated atherosclerosis associated to RA is not yet fully understood, and reliable and specific markers of early cardiovascular involvement are still lacking. Asymmetric dimethylarginine is gaining attention for its implication in the pathogenesis of endothelial dysfunction and as biomarkers of subclinical atherosclerosis. Moreover, the metabolic pathway of methylarginines offers possible targets for therapeutic interventions to decrease the cardiovascular risk. The purpose of this review is to describe the main causes of increased methylarginine levels in RA, their implication in accelerated atherosclerosis, the possible role as biomarkers of cardiovascular risk, and finally the available data on current pharmacological treatment.

AB - Asthma is an inflammatory disease in which proinflammatory cytokines have a role in inducing abnormalities of airway smooth muscle function and in the development of airway hyperresponsiveness. Inflammatory cytokines alter calcium (Ca2+) signaling and contractility of airway smooth muscle, which results in nonspecific airway hyperresponsiveness to agonists. In this context, Ca2+ regulatory mechanisms in airway smooth muscle and changes in these regulatory mechanisms encompass a major component of airway hyperresponsiveness. Although dynamic Ca2+ regulation is complex, phospholipase C/inositol tris-phosphate (PLC/IP3) and CD38 cyclic ADP-ribose (CD38/cADPR) are two major pathways mediating agonist-induced Ca2+ regulation in airway smooth muscle. Altered CD38 expression or enhanced cyclic ADP-ribosyl cyclase activity associated with CD38 contributes to human pathologies such as asthma, neoplasia, and neuroimmune diseases. This review is focused on investigations on the role of CD38-cyclic ADP-ribose signaling in airway smooth muscle in the context of transcriptional and posttranscriptional regulation of CD38 expression. The specific roles of transcription factors NF-kB and AP-1 in the transcriptional regulation of CD38 expression and of miRNAs miR 140-3p and miR-708 in the posttranscriptional regulation and the underlying mechanisms of such regulation are discussed. PMID- 29576750 TI - Infant-Mother and Infant-Caregiver Emotional Relationships: Process Analyses of Interactions in Three Contemporary Childcare Arrangements. AB - Emotional relationships in infant-mother dyads in families where mothers provided full-time (MC) childcare were compared with those of families where mothers used in-home childcare (IHC) providers and family childcare (FCC) providers (N = 245). Infant relationships with childcare providers were also studied. Emotional relationships were adequate in all 3 childcare arrangements, but infant-mother dyads in IHC arrangements displayed healthier emotional relationships than infant mother dyads in MC arrangements; no differences in the health of emotional relationships with infants emerged among the three types of childcare providers (MC, IHC, FCC). Infant-mother dyads in IHC arrangements also displayed healthier emotional relationships than infant-IHC caregiver dyads, but infant-mother and infant-caregiver dyads were comparable in FCC families. Emotional relationships in infant-mother and infant-caregiver dyads were not correlated, regardless of the type of childcare. PMID- 29576748 TI - The Role of Toll-Like Receptor Signaling in the Progression of Heart Failure. AB - Medical systems worldwide are being faced with a growing need to understand mechanisms behind the pathogenesis of heart failure (HF) that is considered as a leading cause of morbidity and mortality around the world. Elevated levels of inflammatory mediators have been identified in patients with HF, which are primarily manifestations of innate immune responses mediated by pattern recognition receptors (PRRs). Toll-like receptors (TLRs), which belong to PRRs, are subjected to the release of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) to generate innate immune responses. More and more emerging data indicate that TLR signaling pathway molecules are involved in the progression of HF. Herein, we present new data with regard to the activation of TLRs in the failing heart, focusing on TLR2, TLR3, TLR4, and TLR9, and suggest the potential use of TLRs in target therapy. PMID- 29576751 TI - Mother-Toddler Cortisol Synchrony Moderates Risk of Early Internalizing Symptoms. AB - Cortisol synchrony is the degree to which mother-toddler cortisol levels are mutually regulated within a dyad. Synchrony's impact on toddler development is not well understood, so this study investigated how synchronous cortisol levels (reactivity and total concentration) in mother-toddler dyads moderates the association between risk factors (i.e., maternal worry, toddler inhibition) and early internalizing symptoms. Seventy mothers and their 2-year-old toddlers provided interpretable saliva samples. Behavioral observations were made to assess the toddler's temperament at age 2, and mothers reported on their toddler's internalizing symptoms when toddlers were 2- and 3-years-old. Results suggest that mother-toddler synchrony in total cortisol concentration moderates the relation between risk factors and internalizing symptoms. Specifically, toddler inhibition and maternal worry were less associated with concurrent toddler internalizing symptoms when dyads demonstrated greater cortisol synchrony in total concentration. Further, synchrony in total cortisol levels marginally moderated the association between toddler inhibition and future internalizing symptoms, such that inhibited toddlers were less likely to demonstrate internalizing symptoms at age 3 when dyads demonstrated more cortisol synchrony. This suggests that cortisol synchrony may serve as an advantageous context that reduces the risk of developing of internalizing symptoms and augments the field's understanding of the implications of shared physiological responses within mother toddler dyads. PMID- 29576752 TI - Nutrient and Antinutrient Compositions and Heavy Metal Uptake and Accumulation in S. nigrum Cultivated on Different Soil Types. AB - Solanum nigrum cultivated on different soil texture types, sandy clay loam, silty clay loam, clay loam, loam, and control soils, were evaluated for proximate compositions, antinutrients, vitamins, and mineral composition with plant age using standard analytical methods. Accumulation of trace elements using translocation factor was studied to determine their toxic levels in plant tissues. Data were analysed by ANOVA and results expressed as means and standard deviation. Ash content, crude fibre, protein, alkaloid, phytate, and saponin ranged between 11.4 and 12%, 19.24 and 19.95%, 34.23 and 38.98, 42.08 and 45.76 mg/ml, 0.84 and 1.17%, and 94.10 and 97.00%, respectively. Vitamins A, C, and B were present in high quantity. Macro- and micronutrients recorded showed that S. nigrum is a potential reservoir of minerals. Accumulation of micronutrients was observed to be the highest at the flowering stage between the 4th and 5th weeks after transplanting. Plants cultivated on clay loam, silty clay loam, and loam soils accumulated elevated nutritional compositions and abundant antinutrients. However, the accumulated trace metals in the plants are within the recommended safe levels. All nutrient values are in the recommended requirements for daily consumption. PMID- 29576753 TI - Autoimmune Retinopathy: Current Concepts and Practices (An American Ophthalmological Society Thesis). AB - Purpose: To elicit and evaluate opinions in the diagnosis and management of nonparaneoplastic autoimmune retinopathy (npAIR) among members of the American Uveitis Society (AUS) and to further the development of consensus and criteria in the diagnosis and management of npAIR. We hypothesize that despite lack of any clear guidelines, a general consensus in the clinical diagnosis and treatment of npAIR exists among uveitis experts. Methods: A literature review was performed and a panel of uveitis experts was consulted to formulate a survey regarding the diagnosis and management of npAIR. An online survey of 10 questions was developed, and a link was distributed through the AUS membership discussion list. We defined "general consensus" as meaning that a majority (>50%) of the respondents provided the same answer to a question. Results: Fifty-four members of the AUS responded to the survey. Thirty-eight members (70.4%) see one to three AIR patients per year. Greater than 50% consensus was reached on most items, particularly items relating to diagnostic features and tests (up to 96% consensus). Conclusions: The diagnosis and management of npAIR is challenging, as standardized clinical and laboratory diagnostic criteria have yet to be established. The results of this study support the presence of consensus regarding certain aspects of npAIR, but also indicate the need for developing clear clinical diagnostic criteria and treatment guidelines.

AB - A simple scheme for dynamically switching the quality factor, Q, of a Loop-Gap Resonator (LGR); working at 250 MHz is presented. The addition of this Q modulator resulted in 30% improvement in Electron Paramagnetic Resonance imager signal-to-noise ratio. During pulse excitation, this scheme lowered the Q, while higher Q was obtained during signal detection. These conditions favored the image acquisition. The Q-modulator is passive; the transition between different states was actuated by the radio frequency power itself. PMID- 29576755 TI - Watch-and-Wait as a Therapeutic Strategy in Rectal Cancer. AB - Purpose of Review: Pathological complete response is seen in approximately one fifth of rectal cancer patients following neoadjuvant chemoradiation. Since these patients have excellent oncological outcomes, there has been a rapidly growing interest in organ preservation for those who develop a clinical complete response. We review the watch-and-wait strategy and focus on all aspects of this hot topic, including who should be considered for this approach, how should we identify treatment response and what are the expected outcomes. Recent Findings: The major challenges in interpreting the data on watch-and-wait are the significant heterogeneity of patients selected for this approach and of methods employed to identify them. The evidence available comes mostly from retrospective cohort studies, but has shown good oncological outcomes, including the rate of successful salvage surgery, locoregional control and overall survival. Summary: There is currently not enough and not robust enough evidence to support watch-and wait as a standard approach, outside a clinical trial, for patients achieving clinical complete response following neoadjuvant chemoradiation. Furthermore, there is a lack of data on long-term outcomes. However, the results we have so far are promising, and there is therefore an urgent need for randomised control studies such as the TRIGGER trial to confirm the safety of this strategy. PMID- 29576756 TI - The importance of thermodynamics for molecular systems, and the importance of molecular systems for thermodynamics. AB - Improved understanding of molecular systems has only emphasised the sophistication of networks within the cell. Simultaneously, the advance of nucleic acid nanotechnology, a platform within which reactions can be exquisitely controlled, has made the development of artificial architectures and devices possible. Vital to this progress has been a solid foundation in the thermodynamics of molecular systems. In this pedagogical review and perspective, we discuss how thermodynamics determines both the overall potential of molecular networks, and the minute details of design. We then argue that, in turn, the need to understand molecular systems is helping to drive the development of theories of thermodynamics at the microscopic scale. PMID- 29576757 TI - Chemical reaction network designs for asynchronous logic circuits. AB - Chemical reaction networks (CRNs) are a versatile language for describing the dynamical behaviour of chemical kinetics, capable of modelling a variety of digital and analogue processes. While CRN designs for synchronous sequential logic circuits have been proposed and their implementation in DNA demonstrated, a physical realisation of these devices is difficult because of their reliance on a clock. Asynchronous sequential logic, on the other hand, does not require a clock, and instead relies on handshaking protocols to ensure the temporal ordering of different phases of the computation. This paper provides novel CRN designs for the construction of asynchronous logic, arithmetic and control flow elements based on a bi-molecular reaction motif with catalytic reactions and uniform reaction rates. We model and validate the designs for the deterministic and stochastic semantics using Microsoft's GEC tool and the probabilistic model checker PRISM, demonstrating their ability to emulate the function of asynchronous components under low molecular count. PMID- 29576758 TI - Programming discrete distributions with chemical reaction networks. AB - We explore the range of probabilistic behaviours that can be engineered with Chemical Reaction Networks (CRNs). We give methods to "program" CRNs so that their steady state is chosen from some desired target distribution that has finite support in [Formula: see text], with [Formula: see text]. Moreover, any distribution with countable infinite support can be approximated with arbitrarily small error under the [Formula: see text] norm. We also give optimized schemes for special distributions, including the uniform distribution. Finally, we formulate a calculus to compute on distributions that is complete for finite support distributions, and can be compiled to a restricted class of CRNs that at steady state realize those distributions. PMID- 29576759 TI - Petri-net-based 2D design of DNA walker circuits. AB - We consider localised DNA computation, where a DNA strand walks along a binary decision graph to compute a binary function. One of the challenges for the design of reliable walker circuits consists in leakage transitions, which occur when a walker jumps into another branch of the decision graph. We automatically identify leakage transitions, which allows for a detailed qualitative and quantitative assessment of circuit designs, design comparison, and design optimisation. The ability to identify leakage transitions is an important step in the process of optimising DNA circuit layouts where the aim is to minimise the computational error inherent in a circuit while minimising the area of the circuit. Our 2D modelling approach of DNA walker circuits relies on coloured stochastic Petri nets which enable functionality, topology and dimensionality all to be integrated in one two-dimensional model. Our modelling and analysis approach can be easily extended to 3-dimensional walker systems.

AB - Introduction: Data processing is one of the biggest problems in metabolomics, given the high number of samples analyzed and the need of multiple software packages for each step of the processing workflow. Objectives: Merge in the same platform the steps required for metabolomics data processing. Methods: KniMet is a workflow for the processing of mass spectrometry-metabolomics data based on the KNIME Analytics platform.

AB - Background: Pelvic endometriosis is often mentioned as one of the variables influencing surgical outcomes of laparoscopic hysterectomy (LH). However, its additional surgical risks have not been well established. The aim of this study was to analyze to what extent concomitant endometriosis influences surgical outcomes of LH and to determine if it should be considered as case-mix variable. Results: A total of 2655 LH's were analyzed, of which 397 (15.0%) with concomitant endometriosis. For blood loss and operative time, no measurable association was found for stages I (n = 106) and II (n = 103) endometriosis compared to LH without endometriosis. LH with stages III (n = 93) and IV (n = 95) endometriosis were associated with more intra-operative blood loss (p = < .001) and a prolonged operative time (p = < .001) compared to LH without endometriosis. No significant association was found between endometriosis (all stages) and complications (p = .62). Conclusions: The findings of our study have provided numeric support for the influence of concomitant endometriosis on surgical outcomes of LH, without bowel or bladder dissection. Only stages III and IV were associated with a longer operative time and more blood loss and should thus be considered as case-mix variables in future quality measurement tools. PMID- 29576762 TI - A bioclimatic characterization of high elevation habitats in the Alborz mountains of Iran. AB - The Alborz mountains in N-Iran at 36 degrees N rise from the Caspian Sea to 5671 m a.s.l., with warm-temperate, winter-deciduous forests in the lower montane belt in northern slopes, and vast treeless terrain at higher elevation. A lack of rainfall (ca. 550 mm at high elevations) cannot explain the absence of trees. Hence, it is an open question, which parts of these mountains belong to the alpine belt. Here we use bioclimatic data to estimate the position of the potential climatic treeline, and thus, define bioclimatologically, what is alpine and what is not. We employed the same miniature data loggers and protocol that had been applied in a Europe-wide assessment of alpine climates and a global survey of treeline temperatures. The data suggest a potential treeline position at ca. 3300 m a.s.l., that is ca. 900 m above the upper edge of the current oak forest, or 450 m above its highest outposts. The alpine terrain above the climatic treeline position shows a temperature regime comparable to sites in the European Alps. At the upper limit of angiosperm life, at 4850 m a.s.l., the growing season lasted 63 days with a seasonal mean root zone temperature of 4.5 degrees C. We conclude that (1) the absence of trees below 2850 m a.s.l. is clearly due to millennia of land use. The absence of trees between 2850 and 3300 m a.s.l. is either due to the absence of suitable tree taxa, or the only potential regional taxon for those elevations, Juniperus excelsa, had been eradicated by land use as well. (2) These continental mountains provide thermal life conditions in the alpine belt similar to other temperate mountains. (3) Topography and snow melt regimes play a significant role for the structure of the alpine vegetation mosaics.

PMID- 29576766 TI - Use of NSAIDs via the Rectal Route for the Prevention of Pancreatitis after ERCP in All-Risk Patients: An Updated Meta-Analysis. AB - The aim of this study was to assess the efficacy of the rectal administration of nonsteroidal anti-inflammatory drugs (NSAIDs) in preventing post-ERCP pancreatitis (PEP). We searched database for randomized controlled trials (RCTs) comparing periprocedural rectal administration of NSAIDs with placebo for the prevention of PEP. The rectal administration of NSAIDs significantly decreased the incidence of PEP in the whole patient population (odds ratio (OR): 0.44, 95% confidence interval (CI): 0.30-0.64, P < 0.0001), high-risk patients (OR: 0.34, 95% CI: 0.19-0.58, P = 0.0001), and all-risk patients (OR: 0.51, 95% CI: 0.31 0.84, P = 0.008). The incidence of PEP was reduced by indomethacin (OR: 0.54, 95% CI: 0.36-0.82, P = 0.004) and diclofenac (OR: 0.27, 95% CI: 0.15-0.46, P < 0.00001). The administration of NSAIDs before (OR: 0.42, 95% CI: 0.25-0.73, P = 0.002) or after (OR: 0.39, 95% CI: 0.27-0.56, P < 0.00001) ERCP reduced PEP. The NSAIDs were associated with a reduction in mild PEP (OR: 0.55, 95% CI: 0.36-0.83, P = 0.004) and moderate-to-severe PEP (OR: 0.47, 95% CI: 0.28-0.79, P = 0.004). The rectal administration of NSAIDs reduced the incidence of PEP in high-risk and all-risk patients. PMID- 29576767 TI - Comparison of Concomitant Mesalamine and Immunomodulator Therapy and Immunomodulator Monotherapy for Crohn's Disease. AB - Background: Although immunomodulators are increasingly used in Crohn's disease (CD), a significant number of gastroenterologists still use 5-aminosalicylate (5 ASA) in combination with azathioprine (AZA) or 6-mercaptopurine (6-MP); there is limited evidence regarding the benefit of concomitant 5-ASA with AZA/6-MP compared with AZA/6-MP monotherapy for the treatment of CD. Study Design: A total of 106 patients who received AZA/6-MP for more than 3 months between January 1991 and May 2014 were identified retrospectively. Each patient was matched with 3 randomly selected controls who were treated with concomitant therapy during the same period. Results: The cumulative probabilities of steroid use at 5 and 10 years were 24.9% and 75.8% in the 5-ASA + AZA/6-MP group and 31.2% and 87.8% in the AZA/6-MP group, respectively (P = 0.187). The cumulative probabilities of anti-TNF use, resectional surgery, and disease-related hospitalization were comparable between the groups. The younger age and the use of lower doses of immunomodulators were associated with higher requirement of rescue therapy. Conclusions: This study did not demonstrate that the concomitant use of 5-ASA with AZA/6-MP showed the proof or effect in terms of steroid requirements, anti TNF use, resectional surgery, or disease-related hospitalization compared with that of AZA/6-MP alone. PMID- 29576769 TI - Favorable Effect of Anti-TNF Therapy on Insulin Sensitivity in Nonobese, Nondiabetic Patients with Inflammatory Bowel Disease. AB - Background: The aim of this study was to investigate the effect of anti-TNF therapy on glucose and lipid metabolism in nondiabetic, nonobese patients with inflammatory bowel disease (IBD). Patients and Methods: We studied 44 patients with IBD, without a known history of diabetes. Three of the patients were diagnosed with overt diabetes and were excluded. Eighteen of the remaining patients (9 M/9 F, 33.6 +/- 8.8 years) were on anti-TNF therapy for longer than 1 year, while 23 patients (16 M/7 F, 38.7 +/- 12.5 years) were treated with aminosalicylates (AMSs). Twelve of the patients from the second group were then treated with anti-TNF and reassessed 6 months later. Fasting glucose, insulin, c peptide, HbA1c, lipid, CRP, and fibrinogen levels were determined, and HOMA-IR index was calculated in all patients. Results: Patients from the two therapy groups were matched for age and BMI and were not obese. We did not find any differences between patients from the two therapy groups regarding fasting glucose, c-peptide, HbA1c, total cholesterol, HDL, LDL, triglycerides, CRP, and HOMA-IR index. In patients who were treated for 6 months with anti-TNF, a statistically significant decrease in insulin (before 15.5 +/- 5.9 versus after 9.9 +/- 2.9 MUIU/ml, p = 0.042) and c-peptide (before 2.4 +/- 1 versus after 1.3 +/- 0.4 ng/ml, p = 0.030) levels as well as the HOMA-IR index (before 4.2 +/- 1.9 versus after 2.2 +/- 0.9, p = 0.045) was observed, without any changes in weight, BMI, glucose, HbA1c, lipid, CRP, and fibrinogen levels. Conclusion: Anti-TNF therapy exerts a favorable effect on insulin sensitivity, while it has no effect on lipid levels in nondiabetic, nonobese patients with inflammatory bowel disease. PMID- 29576768 TI - Effect of Endotoxemia in Suckling Rats on Pancreatic Integrity and Exocrine Function in Adults: A Review Report. AB - Background. Endotoxin (LPS), the component of Gram-negative bacteria, is responsible for sepsis and neonatal mortality, but low concentrations of LPS produced tissue protection in experimental studies. The effects of LPS applied to the suckling rats on the pancreas of adult animals have not been previously explored. We present the impact of neonatal endotoxemia on the pancreatic exocrine function and on the acute pancreatitis which has been investigated in the adult animals. Endotoxemia was induced in suckling rats by intraperitoneal application of LPS from Escherichia coli or Salmonella typhi. In the adult rats, pretreated in the early period of life with LPS, histological manifestations of acute pancreatitis have been reduced. Pancreatic weight and plasma lipase activity were decreased, and SOD concentration was reversed and accompanied by a significant reduction of lipid peroxidation products (MDA + 4 HNE) in the pancreatic tissue. In the pancreatic acini, the significant increases in protein signals for toll-like receptor 4 and for heat shock protein 60 were found. Signal for the CCK1 receptor was reduced and pancreatic secretory responses to caerulein were diminished, whereas basal enzyme secretion was unaffected. These pioneer studies have shown that exposition of suckling rats to endotoxin has an impact on the pancreas in the adult organism. PMID- 29576770 TI - The cold ceramic material. AB - The purpose of this paper was to review the composition, sealing ability, biocompatibility and various physical properties of cold ceramic (CC) material that potentially used as a root filling material. The review of the articles was performed by electronic and manual searching methods regarding the properties of CC from November 2000 to May 2016. The results revealed that there were many published reports carried out on the properties of CC. Only one article had extensively studied the composition of CC, five studies had investigated the sealing ability of CC, three articles had studied the biocompatibility, and some studies had investigated the radiopacity, setting time, pH value, and solubility of CC. It was concluded that CC material had good potential for endodontic use. Furthermore, clinical studies are needed in these areas. PMID- 29576771 TI - Effects of artifact removal on cone-beam computed tomography images. AB - Background: Dental implants and metal fillings may cause artifacts in cone-beam computed tomography (CBCT) images and reduce image quality and anatomic accuracy. The purposes of this study are a subjective evaluation of anatomic landmarks and linear bone measurements after applying artifact removal (low-medium) option on CBCT images. Materials and Methods: In this cross-sectional study, thirty CBCT images from thirty qualified patients were selected in a private radiology center. Low and medium artifact removal was applied to images. Three radiologists assessed the visibility of the mandibular canal, mental foramen, and lamina dura in images. Crestal width and bone length were also measured in three groups of images and was compared by exact McNemar test. ICC test (two-way random model, absolute agreement types) was calculated for comparison of linear bone measurements in three images groups. P <= 0.05 was considered statistically significant. Results: Percent agreement of determining mental foramen (outline and location), mandibular canal (outline and location), and lamina dura between three groups of images were 100%, 100%, 83.3%, 96.7%, and 56.6%, respectively. The results of exact McNemar test revealed that medium artifact removal group had a statistical difference in lamina dura observation with none and low artifact removal groups (P < 0.001). Intraclass correlation coefficient showed no statistical differences in crestal width and bone length between groups (P < 0.001). Conclusion: Applying artifact removal does not affect the visibility of large anatomical structures and linear bone measurements, but delicate structures such as lamina dura may become less clear after artifact removal.

AB - Background: This clinical trial investigated the effectiveness of two remineralizing creams on regression of white spot lesions (WSLs) after orthodontic therapy. Materials and Methods: The study included patients with WSLs on their upper anterior teeth who recently completed orthodontic treatment at the Department of Orthodontics of Mashhad Dental School and two private offices. The participants were randomly assigned into three groups by treatment: (1) a 12-week regimen of a cream containing casein phosphopeptide-amorphous calcium phosphate and fluoride (MI Paste Plus); (2) a 12-week regimen of a cream containing hydroxyapatite and fluoride (Remin Pro); and (3) usual home care (control). Thirty-nine patients participated and three withdrew. The main outcomes including area, mineral content, and color of WSLs were measured at enrolment and 4, 8, and 12 weeks later, respectively. Blinding was applied for outcome assessment only. The data were analyzed by analysis of variance and repeated measures analysis at the statistical significance of P < 0.05. Results: Over a 3-month period, the application of both MI Paste Plus and Remin Pro caused significantly greater reduction in area and significantly higher increase in mineral content of WSLs compared to the control group (P < 0.05). The appearance of WSLs improved significantly in both experimental groups (P < 0.05), but not in the control group. No side effect was observed throughout the experiment. Conclusion: The application of either MI Paste Plus or Remin Pro was effective in reducing the area, increasing the mineral content and improving the appearance of demineralized enamel, indicating that these products could be recommended for managing postorthodontic WSLs.

AB - Background: Visfatin, also known as nicotinamide phosphoribosyltransferase, has been suggested as a pro-inflammatory and immunomodulating marker for periodontitis. The aim of this study was an immunohistochemical analysis of visfatin in gingival tissues of patients with chronic periodontitis and aggressive periodontitis. Materials and Methods: In this cross-sectional study based on clinical evaluation and inclusion and exclusion criteria. Twenty patients with generalized chronic periodontitis, 13 patients with generalized aggressive periodontitis, and 20 periodontally healthy individuals enrolled. Gingival tissue samples were obtained during periodontal flap surgery and crown lengthening surgery in periodontal patients and healthy group, respectively. Tissue samples were transferred to a pathology laboratory to determine the degree of inflammatory infiltration by hematoxylin and eosin staining and the level of visfatin expression by immunohistochemistry. The data were analyzed using SPSS version 20 statistical software and paired t-test, Mann-Whitney test, and Spearman rank correlation coefficient. P < 0.05 was considered statistically significant. Results: Inflammation grading and visfatin expression were significantly higher in periodontally diseased gingiva compared to the control group (P < 0.05). However, no significant difference was found between two diseased groups. The relationship between inflammation grading and visfatin expression in aggressive periodontitis group was statistically significant, positive and relatively strong (P = 0.025, r = 0.617). However, no significant relationship has been found between visfatin expression and inflammation grading in the chronic periodontitits and control groups (P > 0.05). Conclusion: Visfatin expression was increased in gingival tissues of chronic periodontitis and aggressive periodontitis patients. Hence, visfatin may have a role in the etiopathogenesis of chronic periodontitis and aggressive periodontitis.

AB - Background: Different irrigating solutions with high antimicrobial activity have been introduced for cleaning of the root canal system. However, effects of Prangos ferulacea (PF), Ziziphora tenuior (ZT), Dracocephalum moldavica (DM), and Ferula gummosa (FG) on oral and dental pathogens have not been extensively evaluated due to their optimal biocompatibility and insignificant side effects. The aim of this study was to evaluate the antibacterial effects of essential oils of mentioned plants on Enterococcus faecalis. Materials and Methods: In this in vitro study the plants were collected from Zanjan Province, Iran. Analysis of the essential oil was carried out by gas chromatography/mass chromatography. Micro broth dilution and disc diffusion methods were used for assessment of the antimicrobial activity, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were evaluated. Results: All the four essential oils had antibacterial effects on E. faecalis, and ZT had the greatest antibacterial activity. Assessment of the mean diameter of the growth inhibition zone showed higher antibacterial activity of PF and ZT than that of chlorhexidine. The MIC and MBC of ZT showed that the antimicrobial activity of ZT against E. faecalis was greater than that of other plants evaluated in this study. Conclusion: The results of this study indicated significant antibacterial effects of the mentioned plants on E. faecalis. The greatest antimicrobial activity belonged to ZT. The current study suggests extraction of effective compounds in these medicinal plants to use them in the clinical setting. PMID- 29576775 TI - A comparative evaluation of Morinda citrifolia, green tea polyphenols, and Triphala with 5% sodium hypochlorite as an endodontic irrigant against Enterococcus faecalis: An in vitro study. AB - Background: Endodontic infections require effective removal of microorganisms from the root canal system for long-term prognosis. Sodium hypochlorite (NaOCl) is the most effective irrigant currently, but potential complications due to its toxicity warrant search for newer alternatives. In this study, the antimicrobial efficacy of Morinda citrifolia (MC), green tea polyphenols and Triphala was compared with 5% NaOCl against Enterococcus faecalis. Materials and Methods: In this in vitro study sixty extracted human premolar teeth were infected with E. faecalis, a Group D Streptococci for 48 h. At the end of 48 h, the vital bacterial population was assessed by counting the number of colony-forming units (CFUs) on blood agar plate. Samples were divided into five groups; Group I (distilled water), Group II (NaOCl), Group III (MC), Group IV (Triphala), and Group V (green tea polyphenols). The samples were irrigated with individual test agents and CFUs were recorded. Kruskal-Wallis test was performed as the parametric test to compare different groups. Student's t-test was used to compare mean values between groups before and after treatment with test agents (P < 0.001). Results: NaOCl was the most effective irrigant the elimination of E. faecalis reinforcing its role as the best irrigant available currently and a gold standard for comparison of the experimental groups. Its antibacterial effect was comparable to Triphala. Among the experimental groups, MC showed the minimum antibacterial effect. Conclusion: The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of NaOCl. PMID- 29576776 TI - Feasibility of micro-computed tomography to detect and classify proximal caries lesions in vitro. AB - Background: Micro-computed tomography (micro-CT) has been widely described as a nondestructive in vitro imaging method although its accuracy for caries detection is still unclear. The aim of this study was to investigate the feasibility of micro-CT to detect and classify proximal caries lesions in posterior teeth, using different protocols. Materials and Methods: In this in vitro study, crowns of 122 human teeth were scanned with Skyscan 1174 (Bruker, Kontich, Belgium) using the full-scan mode (360 degrees ). Reconstruction of 900 basis images was performed using NRecon Software (Bruker, Kontich, Belgium) for the protocol 1 (full-scan mode 360 degrees ), and 450 basis images were used to reconstruct the protocol 2 (half-scan mode 180 degrees ). Three observers analyzed the reconstructed images concerning the presence and depth of proximal caries lesions (244 surfaces). To determine the presence/absence and depth of caries lesions, histological examination was conducted as reference standard level of significance McNemar and McNemar-Bowker tests compared the methods studied and the gold standard (P < 0.05). Results: The intra- and inter-observer agreement for both methods ranged from moderate to excellent. There was no difference between both micro-CT methods and histology for the presence of lesions (P > 0.05). However, both methods differed with the reference standard for depth (P < 0.05). The disagreement occurred mostly in cases of enamel lesions. The highest diagnostic values were found for 180 degrees rotation. Micro-CT performed well in detecting caries lesions compared to histology, meanwhile the classification of their depth presented lower values. Scan mode did not influence the detection. Conclusion: Both protocols of micro-CT tested presented an overall satisfactory performance in detecting proximal caries lesions; however, for the depth classification, the method was not accurate. PMID- 29576777 TI - Evaluation of the wettability of a resin-based sealer in contact with some herbal irrigants. AB - Background: An ideal root canal irrigant should be able to enhance the wettability of sealer to dentin walls. The aim of this study was to survey the contact angle between AH 26 sealer and dentin surface irrigated by four herbal essential oils, compared with normal saline and 5.25% sodium hypochlorite (NaOCl). Materials and Methods: In this in vitro study, 60 longitudinal dentin slices were obtained from thirty extracted single-rooted human mandibular first premolars. After smear layer removal, the samples were divided into six groups of 10 samples and irrigated for 1 min with the experimental solutions followed by distilled water: G1: Myrtus communis, G2: Cinnamomum zeylanicum, G3: Zataria multiflora (ZM), G4: Cuminum cyminum (CC), G5: normal saline, and G6: NaOCl 5.25%. The contact angle between AH 26 and the samples was measured using Motic Images Plus 2.0 software. Data were analyzed statistically using one-way analysis of variance (P < 0.05 consider significant). Results: All the herbal irrigants, except CC, increased the contact angle of AH 26 sealer (P <= 0.05). The least value of contact angle was seen in the samples treated with CC, and the maximum value was observed in samples treated with ZM. 5.25% NaOCl showed a slightly increased contact angle compared to normal saline; however, it was not statistically significant (P > 0.05). Conclusion: Under the experimental condition of this study, CC was able to increase dentin wettability and therefore may be regarded as a promising irrigant after careful evaluation of other properties of this irrigant. PMID- 29576778 TI - Cytotoxicity assessment of polyhydroxybutyrate/chitosan/nano- bioglass nanofiber scaffolds by stem cells from human exfoliated deciduous teeth stem cells from dental pulp of exfoliated deciduous tooth. AB - Background: The aim of this study was to compare the cytotoxicity and the biocompatibility of three different nanofibers scaffolds after seeding of stem cells harvested from human deciduous dental pulp. Given the importance of scaffold and its features in tissue engineering, this study demonstrated the construction of polyhydroxybutyrate (PHB)/chitosan/nano-bioglass (nBG) nanocomposite scaffold using electrospinning method. Materials and Methods: This experimental study was conducted on normal exfoliated deciduous incisors obtained from 6-year-old to 11-year-old healthy children. The dental pulp was extracted from primary incisor teeth which are falling aseptically. After digesting the tissue with 4 mg/ml of type I collagenase, the cells were cultured in medium solution. Identification of stem cells from human exfoliated deciduous teeth was performed by flowcytometry using CD19, CD14, CD146, and CD90 markers. Then, 1 * 104 stem cells were seeded on the scaffold with a diameter of 10 mm * 0.3 mm. Cell viability was evaluated on days 3, 5, and 7 through methyl thiazol tetrazolium techniques (P < 0.05) on different groups that they are groups included (1) PHB scaffold (G1), (2) PHB/chitosan scaffold (G2), (3) the optimal PHB/chitosan/nBG scaffold (G3), (4) mineral trioxide aggregate (MTA), and (5) the G3 + MTA scaffold (G3 + MTA). Data were analyzed with two-way ANOVA at significance level of P < 0.05. Results: The results indicated that the PHB/chitosan/nBG scaffold and PHB/chitosan/nBG scaffold + MTA groups showed significant difference compared with the PHB/chitosan scaffold and PHB scaffold groups on the 7th day (P < 0.05). Conclusion: Thus, it can be concluded that the scaffold with nBG nanoparticles is more biocompatible than the other scaffolds and can be considered as a suitable scaffold for growth and proliferation of stem cells. PMID- 29576779 TI - Effect of containing silica fume on cytotoxicity of white mineral trioxide aggregate. AB - Background: Mineral trioxide aggregate (MTA) has a high biocompatibility and its physical properties could be improved by adding the containing silica fume an amorphous silicon dioxide (condensed silica fume [CSF]). The aim of this study was to evaluate the cytotoxicity of MTA mixed with CSF on the viability of L929 mouse fibroblast cell using 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide reduction assay (MTT assay). Materials and Methods: In this in vitro study white MTA was mixed with distilled water according to the manufacturer's instructions. Mixtures of White MTA with 10%, 15%, and 20% CSF by weight were prepared and mixed with distilled water. Cytotoxicity of mixtures was compared with MTT assay on L929 mouse fibroblast cell line after 24, 48, and 72 h. Differences in cytotoxicity were assessed by one-way analysis of variance (ANOVA). Results: Mean +/- SD of vital cell counts cultured in MTA, MTA + 10% CSF, MTA + 15% CSF, and MTA + 20% CSF were 98% +/- 6%, 97% +/- 6%, 94% +/- 4%, and 98% +/- 4%, respectively. One-way ANOVA did not reveal any statistically significant difference between the groups (P > 0.05). Conclusion: It may be concluded that addition of CSF to MTA may not influence its cytotoxicity. PMID- 29576780 TI - Chair time saving method for treatment of an impacted maxillary central incisor with 15-month follow-up. AB - Maxillary permanent incisors have a major role in facial esthetics. Impaction of them has great adverse effect on smile and causes serious concerns in patient and parents. Physical barriers (e.g., overretained primary teeth, supernumerary teeth, and pathologic lesions), space problems, developmental abnormalities, altered eruption sequence, trauma, palatal clefts, and genetics can act as etiologic factors. Currently, the conventional technique to treatment of impacted teeth consists of a combined orthodontic and surgical approach, to guide the impacted teeth in a constant position and surrounded by normal hard and soft tissues. Treatment is challenging because of some limitations such as patient's age, cooperation, anchorage, and mechanotherapy possibilities. Hence, sophisticated treatment planning is crucial. A 9-year-old girl with horizontally impacted maxillary left central incisor treated with surgical exposure and closed orthodontic forced eruption with 2 * 4 partial setup fixed appliances. Force was applied with 0.014 inch nickel-titanium wire as elastic overlay and handmade ligated bracket. To save chair time in each appointment, the overlay was activated by twisting of ligature wire extensions around it. After 16-month treatment, impacted incisor emerged in oral cavity, with accepted alignment and inclination. Handmade ligated bracket with ligature wire extensions is useful for the treatment of impacted teeth. Due to easy activation of overlay in this method, chair time become short in each appointment. PMID- 29576781 TI - The New Mayo Clinic Risk Score Characteristics in Acute Coronary Syndrome in Patients Following Percutaneous Coronary Intervention. AB - Background: Mortality and major adverse cardiac events (MACE) frequently occur after percutaneous coronary intervention (PCI). Therefore, the ability to predict such events through an established risk stratification method is of great importance. The present study was aimed at determining the risk stratification of mortality and MACE in post-PCI patients at the intensive cardiac care unit of Cipto Mangunkusumo Hospital (CMH) using 7 variables of the New Mayo Clinic Risk Score (NMCRS). Method: This cross-sectional study drew upon secondary data gathered from the medical records of 313 patients that underwent PCI at the intensive cardiac care unit (ICCU) of CMH between August 1st, 2013, and August 31st, 2014. The primary end point was all-cause mortality and MACE. Seven variables in the NMCRS, namely age, left ventricular ejection fraction, serum creatinine, preprocedural cardiogenic shock, myocardial infarction, and peripheral arterial disease, were evaluated. Results: The mortality and MACE incidence rates in the post-PCI patients were 3.8% (95%CI: 2.6-5.0) and 8.3% (95% CI: 6.6-10.0), respectively. Regarding the NMCRS stratification, elderly patients with lower left ventricular ejection fraction, increased serum creatinine, preprocedural cardiogenic shock, myocardial infarction, and peripheral arterial disease had higher mortality and MACE incidence rates among the post-PCI patients. The mortality and MACE incidence rates significantly increased in the post-PCI patients with a higher NMCRS. Conclusion: Patients with a higher NMCRS had a tendency toward higher mortality and MACE incidence rates following PCI. PMID- 29576782 TI - Extent of Coronary Stenosis and Anxiety Symptoms among Patients Undergoing Coronary Angiography. AB - Background: The association between coronary angiographic findings and the level of anxiety symptoms among patients who undergo coronary angiography is not known. The aim of this study was to investigate the association between the extent of coronary stenosis and anxiety symptoms in patients who undergo coronary angiography. Methods: In a cross-sectional study, 106 patients who underwent coronary angiography and had varying degrees of coronary artery disease were enrolled. Demographic characteristics (i.e., age and gender), socioeconomic status (i.e., educational attainment, income, and marital status), and traditional risk factors (i.e., hypertension, diabetes mellitus, hyperlipidemia, and smoking) were measured. The independent variable was the extent of coronary stenosis shown by coronary angiography, coded as single-vessel disease (n = 19), 2-vessel disease (n = 28), or 3-vessel disease (n = 59). The main outcome was symptoms of anxiety measured using the Hospital Anxiety Depression Scale (HADS). The Kruskal-Wallis test was used for bivariate analysis, and linear regression was applied for multivariable analysis. Results: Participants were mostly men (n = 78, 73%), at a mean age of 50.14 +/- 10.60 years. We found an inverse association between the extent of coronary stenosis and anxiety symptoms in our samples. Anxiety symptoms were lowest in the patients with 3-vessel disease and highest in those with single-vessel disease. The above association remained significant in a linear regression model, controlled for the demographic, socioeconomic, and traditional risk factors. Conclusion: An inverse association may exist between the extent of coronary stenosis and the severity of anxiety symptoms in patients who undergo coronary angiography. Patients who undergo angiography and have fewer angiographic findings require screening for anxiety symptoms. PMID- 29576783 TI - Nigerian Children with Acquired Heart Disease: The Experience in Lagos. AB - Background: Most of the recent reports on acquired heart diseases (AHDs) among Nigerian children are either retrospective or cover a short period of time with fewer subjects. The last report on AHDs among children in Lagos was about a decade ago; it was, however, not specific to children with AHDs but was part of a report on structural heart diseases among children in Lagos. The present study was carried out to document the prevalence and profile of different AHDs in children and to compare the findings with those previously reported. Methods: We conducted a quantitative, nonexperimental, prospective, and cross-sectional review of all consecutive cases of AHDs diagnosed with echocardiography at the Lagos State University Teaching Hospital between January 2007 and June 2016. Comparisons between the normally distributed quantitative data were made with the Student t test, while the chi2 test was applied for the categorical data. Results: The subjects with AHDs were 73 males and 52 females, with a male-to female ratio of 1.4:1. The children were aged 15 days to 14 years, with a mean of 6.61 +/- 4.26 years. Rheumatic heart disease was the most common AHD, documented in a quarter of the children, followed by dilated cardiomyopathy and pericardial effusion in 20.8% and 17.3%, respectively. Less common lesions encountered were Kawasaki disease, mitral valve prolapse, hyperdynamic circulation, and supraventricular tachycardia. Conclusion: Rheumatic heart disease was still the most common AHD in the children in the present study. Dilated cardiomyopathy and pericardial effusion are on the increase as has been reported earlier. PMID- 29576784 TI - Congenital Aortico-Left Ventricular Tunnel: A Case Report of a Rare Cause of Aortic Regurgitation in Adults. AB - The aortico-left ventricular tunnel is a rare congenital abnormality resulting in a pathologic connection between the aorta and the left ventricle. It often presents during infancy or early childhood as a cardiac failure symptom or an incidental finding of a cardiac murmur due to severe aortic regurgitation. It is, however, also occasionally found in asymptomatic adults. We describe a 20-year old female presenting with palpitations in whom clinical evaluations with echocardiography and computed tomography angiography led to the diagnosis of severe aortic regurgitation caused by a tunnel connecting the right sinus of the aorta to the left ventricle. The patient underwent successful obstruction of the tunnel with an autologous pericardial patch and the repair of the dilated aortic root via the reduction aortoplasty technique. She was discharged on the 5th postoperative day with no complications. At 1 month's follow-up, she remained asymptomatic and echocardiography showed aortic valve competence with no residual regurgitation. PMID- 29576785 TI - Incidental Finding of a Large Mobile Aortic Arch Mass during Conventional Angiography. AB - Thromboembolism occurs commonly in general practice and leads to significant health burden. Apart from cardiac sources, aortic atherosclerotic plaques contribute considerably to thromboembolism. A 63-year-old diabetic hypertensive woman referred to our center due to exertional chest pain unresponsive to optimal medical therapy and underwent coronary angiography. Owing to resistance during guide-wire advancement, an aortography was performed. Aortic arch injection demonstrated a large suspended mass distal to the left subclavian artery with free movement in the descending thoracic aorta. Echocardiography revealed widespread atherosclerotic changes in the aortic arch with a large hypermobile mass. Dual-source multi-slice (2 * 128:256) computed tomography angiography of the whole aorta revealed a large floating mass (in favor of a thrombus) in the distal portion of the arch. The patient underwent coronary artery bypass grafting due to severe coronary artery disease. The intra-aortic mass, which was actually a large atherosclerotic plaque, was resected at the same session. She was discharged uneventfully and during a 1-year follow-up, she had no embolic events. PMID- 29576786 TI - Malignant Hyperthermia: Report of Two Cases with a Neglected Complication in Cardiac Surgery. AB - Malignant hyperthermia (MH) can develop after contact with volatile anesthetics (halothane, enflurane, isoflurane, sevoflurane, and desflurane) as well as succinylcholine and cause hypermetabolism during anesthesia, which is associated with high mortality when untreated. Early diagnosis and treatment could be life saving. During cardiac surgery, hypothermia and cardiopulmonary bypass make the diagnosis of MH extremely challenging compared with other settings such as general surgery. We herein report 2 cases of MH, graded as "very likely" or "almost certain" based on the MH clinical grading scale. A 14-month-old infant and a 53-year-old male underwent surgery for severe pulmonary valve stenosis and mitral valve replacement, respectively. Both of them were extubated on the operation day, but they deteriorated with the development of high-grade fever, hypotension, renal failure, and acidosis. The first case had muscle spasms. Unfortunately, the delayed symptoms of MH in the early postoperative course were not diagnosed in these 2 cases, which caused permanent neurologic damage in the first case and death in the second one. However, the infant was discharged from the hospital after 2 months. PMID- 29576787 TI - Management of Cardiovascular Disorders in Patients with Noonan Syndrome: A Case Report. AB - The Noonan syndrome is a rare disorder, one of whose major complications is cardiovascular involvement. A wide spectrum of congenital heart diseases has been observed in this syndrome. The most common cardiac disorder is pulmonary valve stenosis, which has a progressive nature. Hypertrophic cardiomyopathy is less common, but its morbidity and mortality rates are high. We herein introduce a 12 year-old boy with the typical findings of the Noonan syndrome. His symptoms began from infancy, and there was a gradual exacerbation in his respiratory and cardiac manifestations with age. The cardiac involvement included right ventricular outflow tract and pulmonary valve stenosis, hypertrophic cardiomyopathy, and subaortic valve stenosis. Due to the progressive course of the disease, surgical repair was done. Although the patient had a difficult postoperative period, his general condition improved and he was discharged. At 3 months' follow-up, his symptoms showed improvement. Additionally, there was a reduction in the echocardiographic parameters of the outflow tract stenosis gradient as well as a significant improvement in the cardiac hemodynamic indices. PMID- 29576788 TI - Successful Treatment of a Catheter-Induced Superior Vena Cava Syndrome through Catheter-Directed Thrombolysis: A Case Report. AB - Superior vena cava (SVC) syndrome is a medical condition resulting from the obstruction of the blood flow through the large central veins. Recently, central venous catheters have been reported as the increasingly common cause of this syndrome. We describe a 56-year-old woman with previous history of metastatic colon cancer, who had recently undergone central venous catheter insertion for her second chemotherapy course. Eight days following port insertion, she presented with signs and symptoms suggestive of acute SVC syndrome, which was successfully managed with catheter-directed thrombolysis. The pre-discharge transesophageal echocardiography and conventional angiography showed a patent SVC. The patient was discharged and remained asymptomatic over a 6-month follow up. This case shows that catheter-directed thrombolysis may be used as a safe treatment for catheter-induced acute SVC syndrome in patients who have undergone catheter insertion in the central vein.

AB - Tripterygium wilfordii Hook.f. (TWHF) is a traditional Chinese herb long used for rheumatoid arthritis (RA) treatment, in modern times, often in the form of various Tripterygium wilfordii Hook.f. preparations (TWPs). This systematic review and meta-analysis focuses on analyzing the clinical efficacy and safety of TWPs in the treatment of RA. Databases were searched to collect the randomized controlled trials (RCTs) on TWPs treating RA published on or before April 10, 2017. Data from 11 studies were included in this meta-analysis. Compared with the control group, TWPs can increase effectiveness, while decreasing erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP), and risk of adverse events. TWPs treatment was also more effective than treatment by conventional western medicine (CWM) and Chinese patent medicine or placebo (COP). TWPs significantly decreased the risk of adverse events compared with the CWM group, but not compared with the COP group. Current evidence shows that TWPs are more effective than other western or Chinese medicines we included in this meta analysis for RA treatment with relatively lower toxicity. PMID- 29576792 TI - Cannabis Essential Oil: A Preliminary Study for the Evaluation of the Brain Effects. AB - We examined the effects of essential oil from legal (THC <0.2% w/v) hemp variety on the nervous system in 5 healthy volunteers. GC/EIMS and GC/FID analysis of the EO showed that the main components were myrcene and beta-caryophyllene. The experiment consisted of measuring autonomic nervous system (ANS) parameters; evaluations of the mood state; and electroencephalography (EEG) recording before treatment, during treatment, and after hemp inhalation periods as compared with control conditions. The results revealed decreased diastolic blood pressure, increased heart rate, and significant increased skin temperature. The subjects described themselves as more energetic, relaxed, and calm. The analysis EEG showed a significant increase in the mean frequency of alpha (8-13 Hz) and significant decreased mean frequency and relative power of beta 2 (18,5-30 Hz) waves. Moreover, an increased power, relative power, and amplitude of theta (4-8 Hz) and alpha brain waves activities and an increment in the delta wave (0,5-4 Hz) power and relative power was recorded in the posterior region of the brain. These results suggest that the brain wave activity and ANS are affected by the inhalation of the EO of Cannabis sativa suggesting a neuromodular activity in cases of stress, depression, and anxiety. PMID- 29576793 TI - What Factors Guide the Selection of Medicinal Plants in a Local Pharmacopoeia? A Case Study in a Rural Community from a Historically Transformed Atlantic Forest Landscape. AB - The criteria that local people use for selecting medicinal plants have been a recurrent topic in pharmacology and ethnobotany. Two of the current hypotheses regarding this phenomenon, ecological apparency and diversification, attempt to explain the inclusion of "apparent" and "non-apparent" and native and exotic taxa, respectively, in local pharmacopoeia. This study addresses the following questions: Do "apparent" and "non-apparent" medicinal plants have the same importance in local pharmacopoeia? Do "non-apparent" plants occupy more local categories of diseases than "apparent" plants? Do native and exotic medicinal plants have the same importance? Do exotic and native plants occupy different local categories of diseases? This study was conducted with householders of a community from Northeastern Brazil. Out of the 66 plant species cited, most were herbs (39 species), followed by trees and shrubs (27). Herbaceous species also occupied more local categories of diseases (51) than tree and shrub species (28). Furthermore, most of the species cited by the informants were exotic (42). Out of the 94 therapeutic applications cited in this research, 65 were treated with exotic species and 29 with native species, distributed among 13 body systems. These results support both the hypotheses of ecological apparency and diversification. PMID- 29576794 TI - The Therapeutic Effects of a Traditional Chinese Medicine Formula Wuzi Yanzong Pill for the Treatment of Oligoasthenozoospermia: A Meta-Analysis of Randomized Controlled Trials. AB - Oligoasthenozoospermia is a crucial factor in male infertility. Wuzi Yanzong (WZYZ) pill is a popular traditional Chinese medicine (TCM) formula which has been used for male infertility treatment for years. However, its effects on semen quality remain controversial. We conducted a preregistered meta-analysis to assess the effect of WZYZ pill for the therapeutic effects on oligoasthenozoospermia. Five randomized controlled trials including 960 participants were selected from databases of domains in North-East Asian regions, PubMed, Embase, and Cochrane Library. WZYZ pill group yielded a greater mean increment on sperm concentration (5 trials: MD 5.99, 95% CI 2.12-9.85, P = 0.002), sperm motility (5 trials: MD 4.57, 95% CI 0.47-8.68, P = 0.03), sperm morphology (2 trials: MD -1.93, 95% CI -4.87-1.01, P = 0.20), activity of acrosomal enzyme (2 trials: MD 28.27, 95% CI 12.41-44.14, P < 0.01), volume of semen (2 trials: MD 0.56, 95% CI 0.21-0.91, P = 0.002), and a decrement of sperm DNA fragmentation index (2 trials: MD -3.82, 95% CI -6.45--1.19, P = 0.004). However, qualities of selected studies were generally unsatisfactory, and there was inherent heterogeneity among some of the outcomes. Despite these limitations, the WZYZ pill improved sperm quality by improving several semen parameters and decreasing DNA damage in oligoasthenozoospermia patients. PMID- 29576795 TI - Effects of Qingshen Granules on the Oxidative Stress-NF/kB Signal Pathway in Unilateral Ureteral Obstruction Rats. AB - Background. The activation of NF-kappa B (NF/kB) signaling pathway plays an important role in the process of epithelial-mesenchymal transition (EMT) and renal interstitial fibrosis (RIF) in renal tubules. The process of oxidative stress reaction in kidney is via excessive reactive oxygen species (ROS) production to activate NF/kB signaling pathway. Qingshen Granule (QSG) is an effective Chinese formula utilized to treat chronic renal failure. Previous studies confirmed that QSG could inhibit RIF in unilateral ureteral obstruction (UUO) rats. In this study, we used UUO rats to investigate the effects of QSG on oxidative stress and the activation of NF/kB signaling. Seventy male Sprague Dawley (SD) rats were randomly divided into a sham group, UUO model group, Qingshen Granules (QSG) high-dose, medium-dose, and low-dose groups, PDTC group, and candesartan group (10 rats in each group). Our study demonstrated that oxidative stress-NF/kB signal pathway contributed to the formation of UUO renal interstitial fibrosis.

AB - We investigated the effects of Apocynum venetum leaf extract (AVLE) on depressive behaviors and neuronal apoptosis in a chronic unpredictable mild stress (CUMS) rat model of depression. Rats were randomly divided into six groups: control, chronic unpredictable mild stress, fluoxetine, AVLE30, AVLE60, and AVLE120. Except for the control group, all rats were submitted to chronic unpredictable mild stress paradigms for four weeks to induce depressive behavior. Neuronal apoptosis was assessed by the terminal deoxynucleotidyl transferase- (TDT-) mediated dUTP-biotin nick end-labeling (TUNEL) method. The expression levels of apoptosis-related proteins, such as B-cell lymphoma 2 (Bcl-2), Bcl-2 Associated X Protein (Bax), cysteine-aspartic acid protease-3 and protease-9 (caspase-3 and caspase-9), cytochrome c (cyt-C), brain-derived neurotrophic factor (BDNF), and cAMP-response element binding (CREB) protein, were evaluated by western blot. Treatment with AVLE (60 or 120 mg/kg/day) significantly improved depressive behavior. Increased apoptosis of hippocampus and cortical neurons were observed in CUMS rats, while 120 mg/kg/day of AVLE significantly reversed these changes and achieved the best antidepressant-like effects among the doses tested. Moreover, AVLE (120 mg/kg) significantly increased Bcl-2, BDNF, and CREB protein expression and decreased Bax, cyt-C, and caspase family protein expression. Our results indicate that AVLE has potent antidepressant activity, likely due to its ability to suppress neuronal apoptosis.

AB - Arctium lappa (A. lappa), Compositae, is considered a potential source of nutrition and is used as a traditional medicine in East Asian countries for centuries. Although several studies have shown its biological activities as an anti-inflammatory agent, there have been no reports on A. lappa with regard to regulatory role in inflammasome activation. The purpose of this study was to investigate the inhibitory effects of A. lappa extract (ALE) on NLRP3 inflammasome activation and explore the underlying mechanisms. We found that ALE inhibited IL-1beta secretion from NLRP3 inflammasome activated bone marrow derived macrophages but not that secreted by NLRC4 and AIM2 inflammasomes activation. Mechanistic studies revealed that ALE suppressed the ATPase activity of purified NLRP3 and reduced mitochondrial reactive oxygen species (mROS) generated during NLRP3 activation. Therefore, the inhibitory effect of ALE on NLRP3 inflammasome might be attributed to its ability to inhibit the NLRP3 ATPase function and attenuated the mROS during inflammasome activation. In addition, ALE significantly reduced the LPS-induced increase of plasma IL-1beta in mouse peritonitis model. These results provide evidence of novel anti-inflammatory mechanisms of A. lappa, which might be used for therapeutic applications in the treatment of NLRP3 inflammasome-associated inflammatory disorders.

AB - The aim of the study was to investigate the effects and underlying mechanism of JKSQP in a rat model of asthma with kidney-yang deficiency (KYD). Materials and Methods. Hydrocortisone (HYD) was used to establish the rat model of KYD; rats were then sensitized and challenged with ovalbumin (OVA). JKSQP was administered to OVA-challenged rats, and the changes in signs and symptoms of KYD were observed. The leukocyte number and subpopulations in bronchoalveolar lavage fluid (BALF) were counted and the cells were stained with Wright-Giemsa dye. Serum adrenocorticotropic hormone (ACTH), corticosterone (CORT), corticotropin releasing hormone (CRH), total immunoglobulin E (IgE), and OVA-specific IgE levels were determined using relevant enzyme-linked immunosorbent assays (ELISA) kits. Results. JKSQP not only reversed the phenomenon of KYD but also significantly inhibited the number of leukocyte and eosinophils in the BALF, increasing the level of interferon (IFN)-gamma and decreasing the levels of interleukin-4 (IL-4) and IgE in the serum compared with the OVA-challenged groups. Conclusions. Taken together, the antiasthma effects of JKSQP were likely mediated by the enhancement of the function of the hypothalamic-pituitary-adrenal axis and the reversal of T helper 1/2 imbalance.

AB - This study was conducted to determine if topical application of Moringa oleifera extracts and its bioconversion product fermented by Rhizopus oligosporus has therapeutic properties enhancement for treatment of atopic dermatitis. Rhizopus oligosporus (KCCM 11232P) was used to ferment Moringa leaves' extracts in this study. Comparison of organic acids and flavonols in Moringa simple extracts and their fermented product by HPLC analysis revealed that concentration of organic acids and flavonols of bioconversion product was lower than that of hot water extracts. The fermentation process is used as a nutrient for isolation of each component by microorganisms and growth of microorganisms. The results demonstrated that MF extracts effectively reduced clinical features based on macrography, scratching count, and severity scores, as well as model's serum IgE level, including histopathological analyses. PMID- 29576800 TI - Effects of Huanglian Jiedu Decoration in Rat Gingivitis. AB - Gingivitis is an inflammatory disease that affects gingival tissues through a microbe-immune interaction. Huanglian Jiedu decoction (HLJD) is used traditionally for clearing and detoxifying in China, which had been reported to possess many pharmacological effects. Rat gingival inflammation model was established by lipopolysaccharide (LPS) injection for 3 consecutive days, and HLJD was given by gavage before LPS injection. After 3 days rats were sacrificed and tissue samples were evaluated. Serum cytokine levels such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured by enzyme-linked immunoabsorbent assay (ELISA). Oxidative stress related molecules such as total antioxidant capacity (T-AOC), malondialdehyde (MDA), and reactive oxygen species (ROS) were determined. Expression of AMP-activated protein kinase (AMPK) and extracellular signal-regulated kinases 1/2 (ERK1/2) signaling pathway were inspected by western blotting. Histological changes of gingival tissues were tested with hematoxylin-eosin (HE) staining. HLJD significantly decreased serum levels of IL-6 and TNF-alpha, suppressed generation of MDA and ROS, and enhanced T-AOC creation. Moreover, HLJD inhibited expressions of AMPK and ERK1/2. The inflammation severity of gingival tissue by HE staining was severe in model group but relieved in HLJD group obviously. HLJD exhibited protective effects against gingival damage through suppressing inflammation reaction and elevating antioxidation power.

This study provided theoretical basement for producing new Chinese medicine against chronic bronchitis. PMID- 29576802 TI - Antiosteoarthritic Effects of ChondroT in a Rat Model of Monosodium Iodoacetate Induced Osteoarthritis. AB - Ganghwaljetongyeum is a traditional Korean herbal medicine used to treat joint pain, limited motion, fever, and swelling; it also inhibits inflammatory processes associated with arthritis. ChondroT, a water extract of Ganghwaljetongyeum, is a new complex herbal medicine. This study investigated the effects of ChondroT using a rat model of monosodium iodoacetate- (MIA-) induced osteoarthritis. Thirty-six rats were randomly divided into three ChondroT groups and a normal, control, and positive control group. Changes in paw edema volume, histopathology, and plantar withdrawal response were analyzed. Further, inflammatory cytokines, arachidonic acids, liver and kidney function, and hematological features were measured. ChondroT significantly decreased paw edema by the 5th day and notably improved articular cartilage damage; it also significantly improved the plantar withdrawal response in terms of both reaction time and force intensity. Moreover, treatment with ChondroT significantly decreased the serum levels of tumor necrosis factor alpha, interleukin-1beta, interleukin-6, and prostaglandin E2 and significantly increased serum aspartate aminotransferase and alanine aminotransferase levels. This study demonstrates that ChondroT has anti-inflammatory and analgesic effects in a MIA-induced osteoarthritis rat model. These results support the clinical relevance of ChondroT for future use in patients with osteoarthritis. However, further studies are required to elucidate the corresponding mechanisms. PMID- 29576803 TI - Materials library collections as tools for interdisciplinary research. AB - This paper examines how materials libraries are used as tools for interdisciplinary collaboration in 3 research projects that inhabit a disciplinary triangle between materials research, design and user needs: PhysFeel, which explores how materials collections can be used in psychological therapies; Light.Touch.Matters, a design-led project to develop new smart materials; and Hands of X, which uses materials collections to develop a bespoke prosthetics service. The paper analyses and contrasts these case studies to better understand the affordances and limitations of materials collections when used as research, translational and design tools. We conclude that in collaborations between materials researchers, designers and end users, tensions arise as a result of the primacy that each partner gives to creativity, the development of new knowledge and to solving societal problems. The use of a materials library addresses many of these issues but is not a panacea for all the problems associated with interdisciplinary working. PMID- 29576804 TI - Nanofibre optic force transducers with sub-piconewton resolution via near-field plasmon-dielectric interactions. AB - Ultrasensitive nanomechanical instruments, including the atomic force microscope (AFM)1-4 and optical and magnetic tweezers5-8, have helped shed new light on the complex mechanical environments of biological processes. However, it is difficult to scale down the size of these instruments due to their feedback mechanisms9, which, if overcome, would enable high-density nanomechanical probing inside materials. A variety of molecular force probes including mechanophores10, quantum dots11, fluorescent pairs12,13 and molecular rotors14-16 have been designed to measure intracellular stresses; however, fluorescence-based techniques can have short operating times due to photo-instability and it is still challenging to quantify the forces with high spatial and mechanical resolution. Here, we develop a compact nanofibre optic force transducer (NOFT) that utilizes strong near-field plasmon-dielectric interactions to measure local forces with a sensitivity of <200 fN. The NOFT system is tested by monitoring bacterial motion and heart-cell beating as well as detecting infrasound power in solution. PMID- 29576805 TI - Dietary Compound Proanthocyanidins from Chinese bayberry (Myrica rubra Sieb. et Zucc.) leaves inhibit angiogenesis and regulate cell cycle of cisplatin-resistant ovarian cancer cells via targeting Akt pathway. AB - Ovarian cancer is the leading cause of death from gynecological malignancy and natural products have drawn great attention for cancer treatment. Chinese bayberry leaves proanthocyanidin (BLPs) with epigallocatechin-3-O-gallate (EGCG) as its terminal and major extension units is unusual in the plant kingdom. In the present study, BLPs showed strong growth inhibitory effects on cisplatin resistant A2780/CP70 cells by inhibiting angiogenesis and inducing G1 cell cycle arrest. BLPs reduced the tube formation in HUVECs and attenuated the wound healing ability in A2780/CP70 cells. BLPs further reduced the level of ROS and targeted Akt/mTOR/p70S6K/4E-BP-1 pathway to reduce the expression of HIF-1alpha and VEGF, and thus inhibited angiogenesis. Furthermore, BLPs induced G1 cell cycle arrest by reducing the expressions of c-Myc, cyclin D1 and CDK4, which was also in accordance with the flow cytometry analysis. Overall, these results indicated that BLPs could be a valuable resource of natural compounds for cancer treatment. PMID- 29576806 TI - Genomic Analysis of Propane Metabolism in Methyl Tert-Butyl Ether-Degrading Mycobacterium Sp. Strain ENV421. AB - Methyl tert-butyl ether (MTBE) is a ground water contaminant with plausible carcinogenic properties. Mycobacterium sp. strain ENV421 cometabolically degrades MTBE and other ethers during the growth on propane as a carbon source. In this study, the 6.2 Mb genome of strain ENV421 was deciphered. The genome sequence revealed the presence of numerous putative propane catabolic genes including genes encoding hydrocarbon oxygenases and short chain alcohol dehydrogenases. These data provide the basis for the elucidation of propane metabolic pathways in strain ENV421 and its application for the remediation of ground water contaminated with toxic ethers. PMID- 29576807 TI - Complete Genome Sequence of Microcystis aeruginosa NIES-2481 and Common Genomic Features of Group G M. aeruginosa. AB - Microcystis aeruginosa is a freshwater bloom-forming cyanobacterium that is distributed worldwide. M. aeruginosa can be divided into at least 8 phylogenetic groups (A-G and X) at the intraspecific level. Here, we report the complete genome sequence of M. aeruginosa NIES-2481, which was isolated from Lake Kasumigaura, Japan, and is assigned to group G. The complete genome sequence of M. aeruginosa NIES-2481 comprises a 4.29-Mbp circular chromosome and a 147,539-bp plasmid; the circular chromosome and the plasmid contain 4,332 and 167 protein coding genes, respectively. Comparative analysis with the complete genome of M. aeruginosa NIES-2549, which belongs to the same group with NIES-2481, showed that the genome size is the smallest level in previously sequenced M. aeruginosa strains, and the genomes do not contain a microcystin biosynthetic gene cluster in common. Synteny analysis revealed only small-scale rearrangements between the two genomes. PMID- 29576808 TI - Important parameters for optimized metal nanoparticles-aided electromagnetic field (EMF) effect on cancer. AB - Background: A number of experimental research findings for the metal nanoparticles (NPs)-mediated EMF photothermal therapy of cancer cells show an intriguing trend of the NPs' size-dependent efficacy. This is a phenomenon we find to trend with the light absorption bandwidth behavior (full width at half maximum) of the NPs and the accompanying electric field enhancement. We find that the nanoparticle sizes that have been reported to produce the optimized effect on cancer cells are of minimum absorption bandwidth and optimized electric field magnitude. While the death of cancer cells under the NPs-aided EMF effect has in the past attracted varied interpretations, either as a thermal or non-thermal effect, photothermal effect has gained a wide acceptance due to the exhibited hyperthermia. However, the exhibited trend of the NPs' size-dependent efficacy is beginning to feature as a possible manifestation of other overlooked underlying or synergistic phenomenal conditions. Method: We present a theoretical model and analysis which reveal that the contribution and efficacy of the metal NPs in the destruction of cancer depend partly but significantly on the accompanying electric field intensity enhancement factor and partly on their absorption cross section. Results: This paper finds that, other than the expected hyperthermia, the metal NPs' sizes for the optimized therapy on cancer cells seem to fulfill other synergistic conditions which need to come to the fore. We find interplay between electric field and thermal effects as independent energy channels where balancing may be important for the optimized EMF effect, in the ratio of about 5:1. The required balancing depends on the absorption bandwidth and absorption cross-section of the NPs, the frequency of EMF used and the relative permittivity of the cancer cells. The NPs' size-dependent efficacy decreases away from the NPs' size of minimum absorption bandwidth, which is around 20 nm for Au NPs or other shapes of equivalent surface area-volume ratio. While the absorption wavelength peak for metal NPs would change with the change of shape, the responsible condition(s) for optimizing the efficacy remains relatively invariable. Conclusion: From the modeling and the analysis of the NPs' size for optimizing the EMF therapy on cancer cells, the ratio of electric field enhancement by metal NPs to the associated thermal effect is a very important factor for efficacy.

AB - Background: Recent studies have shown that there is an increased risk of Epithelial Ovarian Cancer (EOC) with Organochlorine Pesticides (OCPs). However, the alteration in the gene expression profile has not been explored so far. The goal of the present study is to understand the probable molecular mechanism of OCPs toxicity towards discovery of dysregulation of signaling pathway associated with differential gene expression and candidate transcriptomic set of markers in the pathophysiology of EOC in OCPs exposed population. Methods: The OCP levels were estimated by gas chromatography and whole genome differential expression study was carried out using expression microarray and candidate genes were validated using Real time RT-PCR. Results: Significant level of OCP residues such as beta-hexachlorocyclohexane (beta-HCH), Heptachlor, Heptachlor epoxide B (HTEB), dichlorodiphenyldichloroethylene (p'p'-DDE) and endosulfan-I was found between healthy and EOC patients. The transcriptome profile of several genes revealed regulation of various important cellular processes such as metabolism, inflammation, cytoskeleton dysregulation of TGF and WNT pathway in EOC cases with high OCPs. Conclusion: This study provides the first evidence showing that differentially expressed genes and dysregulation of signaling pathways might be associated with significant level of OCPs exposure in ovary tissue of epithelial ovarian cancer patients. Moreover, significant correlation of these genes with OCPs revealed that OCPs exposure played vital role in dysregulation of related pathways in the etiology of EOC. PMID- 29576812 TI - Cognitive and Language Deficits in Multiple Sclerosis: Comparison of Relapsing Remitting and Secondary Progressive Subtypes. AB - Objective: The objective of this study was to investigate the pattern and severity of cognitive and language impairment in Greek patients with Relapsing remitting (RRMS) and Secondary Progressive Multiple Sclerosis (SPMS), relative to control participants. Method: A prospective study was conducted in 27 patients with multiple sclerosis (PwMS), (N= 15) with RRMS, (N= 12) with SPMS, and (N= 12) healthy controls. All participants were assessed with a flexible comprehensive neuropsychological - language battery of tests that have been standardized in Greece and validated in Greek MS patients. They were also assessed on measures of disability (Expanded Disability Status Scale; EDSS), fatigue (Fatigue Severity Scale; FSS) and depression (Beck Depression Inventory - fast screen; BDI-FS). Results: Our results revealed that groups were well matched on baseline demographic and clinical characteristics. The two clinical groups (RRMS; SPMS) did not differ on overall global cognitive impairment but differed in the initial encoding of verbal material, mental processing speed, response inhibition and set shifting. RRMS patients differed from controls in the initial encoding of verbal material, learning curve, delayed recall of verbal information, processing speed, and response inhibition. SPMS patients differed in all utilized measures compared to controls. Moreover, we noted increased impairment frequency on individualized measures in the progressive SPMS group. Conclusion: We conclude that MS patients, irrespective of clinical subtype, have cognitive deficits compared to healthy participants, which become increasingly worse when they convert from RRMS to SPMS.On the contrary,the pattern of impairment remains relatively stable. PMID- 29576813 TI - Determining the Actual Prevalence of Hepatitis B in Khyber Pakhtunkhwa-Pakistan: A Meta-Analysis. AB - Background: Hepatitis B is considered the most dangerous among the five types of Hepatitis, as it is clinically asymptomatic. It can silently damage the liver over many years without being diagnosed. Hepatitis B is one of the top risks of liver complications in Khyber Pakhtunkhwa (KP), a province of Pakistan, with an average prevalence rate of 2.70%. Aims: We aimed to carefully review the previously published data on prevalence of Hepatitis B Virus (HBV) in KP-Pakistan and use the statistical approach to obtain more precise estimate of the prevalence of HBV in KP-Pakistan. This study on one hand will provide a more reliable and consolidated estimate (pooled estimate) of HBV in the stated region, on the other hand, it enabled us to judge the heterogeneity among the estimates found from these studies. The study is intended to provide more authentic prevalence record and help government/ non-government organizations and health professionals, which plan to initiate HBV prevention programs in KP-Pakistan. Methods: A meta-analysis was performed based on studies found in literature search from electronic databases and bibliography on the prevalence of HBV in KP Pakistan from 2007 to 2017. Abstracts and results of twenty papers were thoroughly studied and the data were extracted. The findings from these studies were distributed in two groups (general and population at high risk) constituting 15 and 5 studies respectively. Results: The combined prevalence by considering random model for the general population of KP-Pakistan was observed to be 2.71%, while population at high risk was reasonably high i.e. 5.64%. By comparing this prevalence rate to the highest global prevalence of HBV in the adult population of Western Pacific Region (6.2%), significant (p-value= 0.000) heterogeneity was observed among the estimates in each group. However, the funnel plot provides a symmetric look, eliminating the effect of publication bias. We can say that HBV has an alarming prevalence rate in KP-Pakistan. However, HBV is thrice more prevalent in male population of KP-Pakistan than the female population. Conclusion: The above results lead that HBV infection has reached an alarming state in KP-Pakistan, though projects like Prime Minister's Program for Prevention & Control of Hepatitis which are contributing in improving the health of the people of KP by trying to prevent and control the incidence of HBV. More massive vaccination and awareness programs should be initiated to prevent the spread of HBV on urgent basis. Provision of diagnostics and treatment facilities against HBV in healthcare units of KP-Pakistan should be assured. PMID- 29576814 TI - Preliminary Data From the Study of Coagulative Profile of HIV Infected Individuals Suggest a Role For Point Mutations in the Gene in Protein S Deficiency in Individuals Undergoing Highly Antiretroviral Therapy. AB - Background: HIV infection is a known prothrombotic condition but factors involved are still controversial. A role for antiretrovirals, especially protease inhibitors, was advocated. Objectives: The study aimed to analyze the levels of anticoagulant proteins in virally suppressed HIV-infected subjects treated with different anti-retroviral regimens. Materials and Methods: Forty-four patients were included in the study. C and PS, D-Dimers and Fibrinogen levels were determined as well as APC-resistance. PROS1 gene was sequenced in a group of patient. Results: Twelve of the 44 subjects (27%) showed reduced levels of PS, while lower levels of PC were found only in 2 patients (4,5%). No difference in the mean values of PC and PS was found stratifying the study population by antiretroviral regimen administrated (p>0.05).Three patients had higher levels of D-Dimer concentrations and in two of these patients, an association between higher D-Dimer values and lower levels of PS was observed; but however no correlation was found by statistical analysis.PROS1 gene analysis was performed in 26 of the 44 HIV-1 patients and the subjects with low levels of PS had mutation in the fifteen exon of PROS 1 gene. While among individuals with normal levels, this mutation was observed only in 8/18 (44%) of the cases (p=0,0072). Conclusion: The majority of patients with low PS levels also had mutations in the fifteen exon of PROS 1 gene. Genetic determinants, deserving further investigations, rather than antiretrovirals might cause PS deficiency in HIV-1 positive patients. PMID- 29576815 TI - Modification of Initial Highly Active Antiretroviral Therapy (HAART) Regimen in Paediatric HIV Patients. AB - Background: Treatment options among Human Immunodeficiency Virus (HIV)-infected children are limited as only a few Highly Active Antiretroviral Therapy (HAART) are approved worldwide for paediatric use. Among children, frequent changes in HAART regimen can rapidly exhaust treatment options, and information addressing this issue is scarce. Objective: The aim of the study was to determine factors associated with the modification of initial HAART regimen modification among HIV infected children. Method: A retrospective study was performed among HIV-infected children aged 18 and below, that received HAART for at least six months in a tertiary hospital in Malaysia. Factors associated with modification of initial HAART regimen were investigated. Results: Out of 99 patients, 71.1% (n=71) required initial HAART regime modification. The most common reason for HAART modification was treatment failure (n=39, 54.9%). Other reasons included drug toxicity (n=14, 19.7%), change to fixed-dose products (n=11, 15.5%), product discontinuation (n=4, 5.6%) and intolerable taste (n=3, 4.2%). The overall mean time retention on initial HAART before regimen modification was 3.32 year +/- 2.24 years (95% CI, 2.79-3.85). Patient's adherence was the only factor associated with initial regimen modification in this study. Participants with poor adherence showed a five-fold risk of having their initial HAART regimen modified compared to those with good adherence (adjusted OR [95% CI], 5.250 [1.614 - 17.076], p = 0.006). Conclusion: Poor adherence was significantly associated with initial regimen modification, intervention to improve patient's adherence is necessary to prevent multiple regimen modification among HIV infected children. PMID- 29576816 TI - Why it Worked: Participants' Insights into an mHealth Antiretroviral Therapy Adherence Intervention in China. AB - Background: Few Antiretroviral Therapy (ART) adherence trials investigate the reasons for intervention success or failure among HIV-positive individuals. Objectives: To conduct qualitative research to explore the reasons for effectiveness of a 6-month mHealth (mobile health) trial that improved adherence among ART patients in China. The intervention utilized Wireless Pill Containers (WPCs) to provide, real-time SMS reminders, WPC-generated adherence reports, and report-informed counseling. Methods: We conducted in-depth interviews with 20 intervention-arm participants immediately following the trial. Sampling was purposeful to ensure inclusion of participants with varied adherence histories. Questions covered adherence barriers and facilitators, and intervention experiences. We analyzed data in nVivo using a thematic approach. Results: Of participants, 14 (70%) were male; 7 (35%) had used injectable drugs. Pre intervention, 11 were optimal adherers and 9 were suboptimal adherers, using a 95% threshold. In the final intervention month, all but 3 (85%) attained optimal adherence. Participants identified a range of adherence barriers and facilitators, and described various mechanisms for intervention success. Optimal adherers at baseline were motivated by positive adherence reports at monthly clinic visits-similar to receiving A+ grades. For suboptimal adherers, reminders facilitated the establishment of adherence-promoting routines; data-guided counseling helped identify strategies to overcome specific barriers. Conclusion: Different behavioral mechanisms appear to explain the success of an mHealth adherence intervention among patients with varying adherence histories. Positive reinforcement was effective for optimal adherers, while struggling patients benefitted from reminders and data-informed counseling. These findings are relevant for the design and scalability of mHealth interventions and warrant further investigation.

AB - It is now known unambiguously that wind-driven bedform activity is occurring on the surface of Mars today, including early detections of active sand dunes in Meridiani Planum's Endeavour crater. Many of these reports are only based on a few sets of observations of relatively isolated bedforms and lack regional context. Here, we investigate aeolian activity across central Meridiani Planum and test the hypothesis that dune sites surrounding Endeavour crater are also active and part of region-wide sediment migration driven by northwesterly winds. All 13 dune fields investigated clearly showed evidence for activity and the majority exhibited dune migration (average rates of 0.6 m/Earth-year). Observations indicate substantial geographic and temporal heterogeneity of dune crest fluxes across the area and per site. Locations with multiple time steps indicate dune sand fluxes can vary by a factor of five, providing evidence for short periods of rapid migration followed by near-stagnation. In contrast, measurements at other sites are nearly identical, indicating that some dunes are in a steady-state as they migrate. The observed sediment transport direction was consistent with a regional northeasterly-to-northwesterly wind regime, revealing more variations than were appreciated from earlier, more localized studies. Craters containing shallow, degraded, flat-floored interiors tended to have dunes with high sediment fluxes/activity, whereas local kilometer-scale topographic obstructions (e.g., central peaks, yardangs) were found to be inversely correlated with dune mobility. Finally, the previous, more limited detections of dune activity in Endeavour crater have been shown to be representative of a broader, region-wide pattern of dune motion. PMID- 29576819 TI - Effect of angioembolisation versus surgical packing on mortality in traumatic pelvic haemorrhage: A systematic review and meta-analysis. AB - BACKGROUND: The management of complex pattern of bleeding associated with pelvic trauma remains a big challenge for trauma surgeons. We aimed to conduct a comprehensive meta-analysis to compare the outcomes of angioembolisation and pelvic packing in patients with pelvic trauma. METHODS: We conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the CENTRAL; the World Health Organization International Clinical Trials Registry; ClinicalTrials.gov; ISRCTN Register, and bibliographic reference lists. The primary outcome was defined as mortality. Combined overall effect sizes were calculated using random-effects models. Results are reported as the odds ratio (OR) and 95% confidence interval (CI). RESULTS: We identified 3 observational studies reporting a total of 120 patients undergoing angioembolisation (n=60) or pelvic packing (n=60) for pelvic trauma. Reporting of the Injury Severity Score (ISS) was variable, with higher ISS in the pelvic packing group. The risk of bias was low in two studies, and moderate in one. The pooled analysis demonstrated that angioembolisation did not significantly reduce mortality in patients with pelvic trauma compared to surgery (OR=1.99; 95% CI= 0.83-4.78, P=0.12). There was mild between-study heterogeneity (I2=0%, P=0.65). CONCLUSION: Our analysis found no significant difference in mortality between angioembolisation and pelvic packing in patients with traumatic pelvic haemorrhage. The current level of evidence in this context is very limited and insufficient to support the superiority of a treatment modality. Future research is required. PMID- 29576820 TI - The Emergency Department Crash Cart: A systematic review and suggested contents. AB - BACKGROUND: As the field of Emergency Medicine grows worldwide, the importance of an Emergency Department Crash Cart (EDCC) has long been recognized. Yet, there is paucity of relevant peer-reviewed literature specifically discussing EDCCs or proposing detailed features for an EDCC suitable for both adult and pediatric patients. METHODS: The authors performed a systematic review of EDCC-specific literature indexed in Pubmed and Embase on December 20, 2016. In addition, the authors reviewed the 2015 American Heart Association (AHA) guidelines for cardiopulmonary resuscitation and emergency cardiovascular care, the 2015 European Resuscitation Council (ERC) guidelines for resuscitation, and the 2013 American College of Surgeons (ACS) Advanced Trauma Life Support (ATLS) 9th edition. RESULTS: There were a total of 277 results, with 192 unique results and 85 duplicates. After careful review by two independent reviewers, all but four references were excluded. None of the four included articles described comprehensive contents of equipment and medications for both the adult and pediatric populations. This article describes in detail the final four articles specific to EDCC, and proposes a set of suggested contents for the EDCC. CONCLUSION: Our systematic review shows the striking paucity of such a high impact indispensable item in the ED. We hope that our EDCC content suggestions help enhance the level of response of EDs in the resuscitation of adult and pediatric populations, and encourage the implementation of and adherence to the latest evidence-based resuscitation guidelines.

AB - BACKGROUND: Airway management in intensive care unit (ICU) patients is challenging. The aim of this study was to compare the rate of successful first pass intubation in the ICU by using the direct laryngoscopy (DL) and that by using the video laryngoscopy (VL). METHODS: A randomized, non-blinded trial comparing first-pass success rate of intubation between VL and DL was performed. Patients were recruited in the period from August 2014 to August 2016. All physicians working at ICU received hands-on training in the use of the video and direct laryngoscope. The primary outcome measure was the first-pass intubation success. RESULTS: A total of 163 ICU patients underwent intubation during the study period (81 patients in VL group and 82 in DL group). The rate of successful first-pass intubation was not significantly different between the VL and the DL group (67.9% vs. 69.5%, P=0.824). Moreover, the overall intubation success and total number of attempts to achieve intubation success did not differ between the two groups. In patients with successful first-pass intubation, the median duration of the intubation procedure did not differ between the two groups. The Cormack-Lehane grades and the percentage of glottic opening score were similar, and no significant differences were found between the two groups. There were no statistical differences between the VL and the DL group in intubation complications (all P>0.05). CONCLUSION: Among ICU patients requiring intubation, there was no significant difference in the rate of successful first-pass intubation between VL and DL. PMID- 29576822 TI - Predisposing factors, clinical assessment, management and outcomes of agitation in the trauma intensive care unit. AB - BACKGROUND: Agitation occurs frequently among critically ill patients admitted to the intensive care unit (ICU). We aimed to evaluate the frequency, predisposing factors and outcomes of agitation in trauma ICU. METHODS: A retrospective analysis was conducted to include patients who were admitted to the trauma ICU between April 2014 and March 2015. Data included patient's demographics, initial vitals, associated injuries, Ramsey Sedation Scale, Glasgow Coma Scale, head injury lesions, use of sedatives and analgesics, head interventions, ventilator days, and ICU length of stay. Patients were divided into two groups based on the agitation status. RESULTS: A total of 102 intubated patients were enrolled; of which 46 (45%) experienced agitation. Patients in the agitation group were 7 years younger, had significantly lower GCS and sustained higher frequency of head injuries (P<0.05). Patients who developed agitation were more likely to be prescribed propofol alone or in combination with midazolam and to have frequent ICP catheter insertion, longer ventilatory days and higher incidence of pneumonia (P<0.05). On multivariate analysis, use of propofol alone (OR=4.97; 95% CI=1.35 18.27), subarachnoid hemorrhage (OR=5.11; 95% CI=1.38-18.91) and ICP catheter insertion for severe head injury (OR=4.23; 95% CI=1.16-15.35) were independent predictors for agitation (P<0.01). CONCLUSION: Agitation is a frequent problem in trauma ICU and is mainly related to the type of sedation and poor outcomes in terms of prolonged mechanical ventilation and development of nosocomial pneumonia. Therefore, understanding the main predictors of agitation facilitates early risk-stratification and development of better therapeutic strategies in trauma patients. PMID- 29576823 TI - Outcomes of severe sepsis and septic shock patients after stratification by initial lactate value. AB - BACKGROUND: In the setting of severe sepsis and septic shock, mortality increases when lactate levels are >= 4 mmol/L. However, the consequences of lower lactate levels in this population are not well understood. The study aimed to determine the in-hospital mortality associated with severe sepsis and septic shock when initial lactate levels are < 4 mmol/L. METHODS: This is a retrospective cohort study of septic patients admitted over a 40-month period. Totally 338 patients were divided into three groups based on initial lactate values. Group 1 had lactate levels < 2 mmol/L; group 2: 2-4 mmol/L; and group 3: >= 4 mmol/L. The primary outcome was in-hospital mortality. RESULTS: There were 111 patients in group 1, 96 patients in group 2, and 131 in group 3. The mortality rates were 21.6%, 35.4%, and 51.9% respectively. Univariate analysis revealed the mortality differences to be statistically significant. Multivariate logistic regression demonstrated higher odds of death with higher lactate tier group, however the findings did not reach statistical significance. CONCLUSION: This study found that only assignment to group 3, initial lactic acid level of >= 4 mmol/L, was independently associated with increased mortality after correcting for underlying severity of illness and organ dysfunction. However, rising lactate levels in the other two groups were associated with increased severity of illness and were inversely proportional to prognosis. PMID- 29576824 TI - Ventilator management for acute respiratory distress syndrome associated with avian influenza A (H7N9) virus infection: A case series. AB - BACKGROUND: Data on the mechanical ventilation (MV) characteristics and radiologic features for the cases with H7N9-induced ARDS were still lacking. METHODS: We describe the MV characteristics and radiologic features of adult patients with ARDS due to microbiologically confirmed H7N9 admitted to our ICU over a 3-month period. RESULTS: Eight patients (mean age 57.38+/-16.75; 5 male) were diagnosed with H7N9 in the first quarter of 2014. All developed respiratory failure complicated by acute respiratory distress syndrome (ARDS), which required MV in ICU. The baseline APACHE II and SOFA score was 11.77+/-6.32 and 7.71+/ 3.12. The overall CT scores of the patients was 247.68+/-34.28 and the range of CT scores was 196.3-294.7. The average MV days was 14.63+/-6.14, and 4 patients required additional rescue therapies for refractory hypoxemia. Despite these measures, 3 patients died. CONCLUSION: In H7N9-infected patients with ARDS, low tidal volume strategy was the conventional mode. RM as one of rescue therapies to refractory hypoxemia in these patients with serious architectural distortion and high CT scores, which could cause further lung damage, may induce bad outcomes and requires serious consideration. Prone ventilation may improve mortality, and should be performed at the early stage of the disease, not as a rescue therapy. PMID- 29576825 TI - Comparison of sedative effectiveness of thiopental versus midazolam in reduction of shoulder dislocation. AB - BACKGROUND: Various sedative drugs have been proposed to control anxiety and agitation in shoulder dislocation, but none of them has been diagnosed as the best sedative and relaxant agent. The study aimed to compare the sedative effectiveness of thiopental versus midazolam in reduction of shoulder dislocation. METHODS: A randomized double-blind controlled trail was performed in 80 patients with shoulder dislocation recruited from the emergency department. Ten patients were excluded and 70 patients were enrolled in the study. Case group received intravenous thiopental 2 mg/kg+2 ug/kg fentanyl while control group received intravenous midazolam 0.1 mg/kg+2 ug/kg fentanyl. Number of times, patients and physician's satisfaction, difficulty of procedure, degree of muscle relaxation, time of sedation and complete recovery, number of patients with apnea episode, O2 saturation, patient's pain score and adverse events were all recorded. RESULTS: Muscular tone had significant difference between the two groups (P-value=0.014) and thiopental was more muscle relaxant than midazolam. Replacement of shoulder dislocation in thiopental group was easier than midazolam group (P-value=0.043). There was no need to use multiple methods of reduction in either group. Before drug infusion the mean+/-SD VAS scores were 8.37+/-2.21 in the midazolam group (A) and 8.94+/-1.78 in the thiopental group (B); mean difference 0.57, 95% CI= -0.38 to 1.52. After completion of the procedure, the mean+/-SD VAS scores in group (A) and (B) were 3.20+/-1.30 vs. 3.65+/-1.30; mean difference -0.45, 95% CI= -1.07 to 0.16. CONCLUSION: Thiopental might be more effective and relaxant than midazolam for reduction of shoulder dislocation. PMID- 29576826 TI - The relative value of education of emergency physicians in patient outcome: A retrospective analysis at a single center in developing India. AB - BACKGROUND: There is a considerable paucity with regards to the research available on the quality and quantity of clinical teaching in the national emergency department (ED) setups. With the onset of the age of modern medicine, the outlook towards to the time worn tradition of triage and detailed medical evaluation must be revoked. Despite the variety of programs being conducted in the country, a comparable entity common to all is patients' clinical outcomes which can be measured using simple parameters which can be easily acquired compiling hospital registry entries. METHODS: A retrospective observational study was conducted in the emergency department of Max Hospital, Saket, New Delhi. A period of 22 months prior to the start of the program and like-wise 22 months after initiation of the program was collected from the hospital registry. The Emergency Medicine program in consideration was the Masters in emergency Medicine (MEM) Program affiliated with George Washington University, NY, USA. Patients of all age groups and gender registering in the Emergency Department and so were all the doctors working in the ED before and after initiation of the program. RESULTS: An improvement was noted in terms of total admissions through the ED per month, average length of stay of admitted as well as discharged patients; return to ED within 24 hours; leave against medical advice and patient complaints. A reduction was noted in number of discharges from the ED. Despite a numerical worsening on the patient's death in ED a graphical improvement can be noted considering the month wise representation of data. CONCLUSION: We can make a coherent conclusion that there is an improvement in the outcome of the entire patient related aspects in the Emergency Department considering the all two time frames included in the study. The difference can be very well attributed to the integration of the structural Academic Program in the development of the Emergency Physicians. This leads us to make a conclusive analysis regarding a positive impact of the Relative Value of Education of Emergency Physicians not only in patient outcome but also in physicians and administrative outlook towards an overall better emergency care. PMID- 29576827 TI - Impact of an educational intervention on medical records documentation. AB - BACKGROUND: Inaccurate and incomplete documentation can lead to poor treatment and medico-legal consequences. Studies indicate that teaching programs in this field can improve the documentation of medical records. The study aimed to evaluate the effect of an educational workshop on medical record documentation by emergency medicine residents in the emergency department. METHODS: An interventional study was performed on 30 residents in their first year of training emergency medicine (PGY1), in three tertiary referral hospitals of Tehran University of Medical Sciences. The essential information that should be documented in a medical record was taught in a 3-day-workshop. The medical records completed by these residents before the training workshop were randomly selected and scored (300 records), as was a random selection of the records they completed one (300 records) and six months (300 records) after the workshop. RESULTS: Documentation of the majority of the essential items of information was improved significantly after the workshop. In particular documentation of the patients' date and time of admission, past medical and social history. Documentation of patient identity, requests for consultations by other specialties, first and final diagnoses were 100% complete and accurate up to 6 months of the workshop. CONCLUSION: This study confirms that an educational workshop improves medical record documentation by physicians in training.

AB - In this article, we report on a new experimental methodology to enable reliable formation of droplet interface bilayer (DIB) model membranes with two types of unsaturated lipids that have proven difficult for creating stable DIBs. Through the implementation of a simple evaporation technique to condition the spontaneously assembled lipid monolayer around each droplet, we increased the success rates of DIB formation for two distinct unsaturated lipids, namely 1,2 dioleoyl-sn-glycero-3-phosphocholine (DOPC) and 1-palmitoyl-2-oleoyl-sn-glycero-3 phosphocholine (POPC), from less than 10% to near 100%. Separately, using a pendant drop tensiometer, we learned that: (a) DOPC and POPC monolayers do not spontaneously assemble into their tightest possible configurations at an oil water interface, and (b) reducing the surface area of a water droplet coated with a partially packed monolayer leads to a more tightly packed monolayer with an interfacial tension lower than that achieved by spontaneous assembly alone. We also estimated from Langmuir compression isotherms obtained for both lipids that the brief droplet evaporation procedure prior to DIB formation resulted in a 6% 16% reduction in area per lipid for DOPC and POPC, respectively. Finally, the increased success rates of formation for DOPC and POPC DIBs enabled quantitative characterization of unsaturated lipid membrane properties including electrical resistance, rupture potential, and specific capacitance. PMID- 29576834 TI - Microfluidic platform for selective microparticle parking and paired particle isolation in droplet arrays. AB - Immobilizing microscale objects (e.g., cells, spheroids, and microparticles) in arrays for direct observation and analysis is a critical step of many biological and chemical assays; however, existing techniques are often limited in their ability to precisely capture, arrange, isolate, and recollect objects of interest. In this work, we present a microfluidic platform that selectively parks microparticles in hydrodynamic traps based on particle physical characteristics (size, stiffness, and internal structure). We present an accompanying scaling analysis for the particle parking process to enable rational design of microfluidic traps and selection of operating conditions for successful parking of desired particles with specific size and elastic modulus. Our platform also enables parking of encoded particle pairs in defined spatial arrangements and subsequent isolation of these pairs in aqueous droplets, creating distinct microenvironments with no cross-contamination. In addition, we demonstrate the ability to recollect objects of interest (i.e., one particle from each pair) after observation within the channel. This integrated device is ideal for multiplexed assays or microenvironment fabrication for controlled biological studies. PMID- 29576835 TI - A rapid and meshless analytical model of acoustofluidic pressure fields for waveguide design. AB - Acoustofluidics has a strong pedigree in microscale manipulation, with particle and cell separation and patterning arising from acoustic pressure gradients. Acoustic waveguides are a promising candidate for localizing force fields in microfluidic devices, for which computational modelling is an important design tool. Meshed finite element analysis is a popular approach for this, yet its computation time increases rapidly when complex geometries are used, limiting its usefulness. Here, we present an analytical model of the acoustic pressure field in a microchannel arising from a surface acoustic wave (SAW) boundary condition that computes in milliseconds and provide the simulation code in the supplementary material. Unlike finite element analysis, the computation time of our model is independent of microchannel or waveguide shape, making it ideal for designing and optimising microscale waveguide structures. We provide experimental validation of our model with cases including near-field acoustic patterning of microparticles from a travelling SAW and two-dimensional patterning from a standing SAW and explore the design of waveguides for localised particle or cell capture. PMID- 29576836 TI - Hairpins in the conformations of a confined polymer. AB - If a semiflexible polymer confined to a narrow channel bends around by 180 degrees , the polymer is said to exhibit a hairpin. The equilibrium extension statistics of the confined polymer are well understood when hairpins are vanishingly rare or when they are plentiful. Here, we analyze the extension statistics in the intermediate situation via experiments with DNA coated by the protein RecA, which enhances the stiffness of the DNA molecule by approximately one order of magnitude. We find that the extension distribution is highly non Gaussian, in good agreement with Monte-Carlo simulations of confined discrete wormlike chains. We develop a simple model that qualitatively explains the form of the extension distribution. The model shows that the tail of the distribution at short extensions is determined by conformations with one hairpin. PMID- 29576837 TI - Enhanced separation of aged RBCs by designing channel cross section. AB - Prolonged storage will alter the biophysical properties of red blood cells (RBCs), and it decreases the quality of stored blood for blood transfusion. It has been known that less deformable aged RBCs can be separated by margination, but the recognition of the storage time from the separation efficiency of the stiff RBCs is still a challenge. In this study, we realized enhanced separation of aged RBCs from normal RBCs by controlling the channel cross section and demonstrated that the storage time can be deduced from the percentage of the separated RBCs in the stored RBCs. This separation technology helps to reveal the regulation of time on the RBC aging mechanism and offer a new method to separate stiffened cells with high efficiency. PMID- 29576838 TI - A low cost, membranes based serum separator modular. AB - To fulfill the requirement of sample preparation in a microfluidic analysis system designed for "sample in, answer out" testing which was urgently needed by resource limited clinical facilities, we proposed a critical low cost, membrane based serum separator design in this article. With a specially designed microchip, this device can easily separate serum from the whole blood sample in 5 min. Different from techniques which have been reported earlier, this approach does not require either centrifugation or sample dilution which may cause hemolysis or decreased testing sensitivity. By applying 300 MUl of the whole blood sample, 50-70 MUl of serum can be recovered from each device, and the serum volume recovery rate compared with centrifuged control is around 73% which is sufficient for most of the microfluidic-based assays. The protein recovery rate ranged from 70% to 95% which was compared with centrifuged control. The evaluation results indicate that this sample preparation device can offer sufficient amount of purified serum sample for any kind of diagnostic assays such as immunoassay and serum nucleic acid assay. PMID- 29576839 TI - Simultaneous detection of multiple HPV DNA via bottom-well microfluidic chip within an infra-red PCR platform. AB - Portable Polymerase Chain Reaction (PCR) devices combined with microfluidic chips or lateral flow stripes have shown great potential in the field of point-of-need testing (PoNT) as they only require a small volume of patient sample and are capable of presenting results in a short time. However, the detection for multiple targets in this field leaves much to be desired. Herein, we introduce a novel PCR platform by integrating a bottom-well microfluidic chip with an infra red (IR) excited temperature control method and fluorescence co-detection of three PCR products. Microfluidic chips are utilized to partition different samples into individual bottom-wells. The oil phase in the main channel contains multi-walled carbon nanotubes which were used as a heat transfer medium that absorbs energy from the IR-light-emitting diode (LED) and transfers heat to the water phase below. Cyclical rapid heating and cooling necessary for PCR are achieved by alternative power switching of the IR-LED and Universal Serial Bus (USB) mini-fan with a pulse width modulation scheme. This design of the IR-LED PCR platform is economic, compact, and fully portable, making it a promising application in the field of PoNT. The bottom-well microfluidic chip and IR-LED PCR platform were combined to fulfill a three-stage thermal cycling PCR for 40 cycles within 90 min for Human Papilloma Virus (HPV) detection. The PCR fluorescent signal was successfully captured at the end of each cycle. The technique introduced here has broad applications in nucleic acid amplification and PoNT devices. PMID- 29576840 TI - Molecular-Fluorescence Enhancement via Blue-Shifted Plasmon-Induced Resonance Energy Transfer. AB - We report molecular-fluorescence enhancement via the blue-shifted plasmon-induced resonance energy transfer (PIRET) from single Au nanorods (AuNRs) to merocyanine (MC) dye molecules. The blue-shifted PIRET occurs when there is a proper spectral overlap between the scattering of AuNRs and the absorption of MC molecules. Along with the quenching of scattering from AuNRs, the blue-shifted PIRET enhances the fluorescence of nearby molecules. On the basis of the fluorescence enhancement, we conclude that AuNRs can be used as donors with clear advantages to excite the fluorescence of molecules as acceptors in AuNR-molecule hybrids. On the one hand, compared to conventional molecular donors in Forster resonance energy transfer (FRET), AuNRs have much larger absorption cross sections at the plasmon resonance frequencies. On the other hand, energy-transfer efficiency of PIRET decreases at a lower rate than that of FRET when the donor-acceptor distance is increased. Besides, the blue-shifted PIRET allows excitation with incident light of lower energy than the acceptor's absorption, which is difficult to achieve in FRET because of the Stokes shift. With the capability of enhancing molecular fluorescence with excitation light of low intensity and long wavelength, the blue shifted PIRET will expand the applications of nanoparticle- molecule hybrids in biosensing and bioimaging by increasing signal-to-noise ratio and by reducing photodamage to biological cells and organelles at the targeted areas. PMID- 29576841 TI - Different Setting Conditions Affect Surface Characteristics and Microhardness of Calcium Silicate-Based Sealers. AB - Objective: To investigate the effect of different setting conditions on surface microhardness and setting properties of calcium silicate-based sealers. Methods: Three sealers, EndoSequence Bioceramic (BC; Brasseler USA, Savannah, GA, USA), Endoseal MTA (ES; Maruchi, Wonju, Korea), and Well-Root ST (WR; Vericom, Chuncheon, Korea), were compared. Specimens were exposed to either butyric acid (pH 5.4) or phosphate-buffered saline (PBS [pH 7.4]) for 48 h and stored at 100% humidity for 12 days. The control specimens were stored at 100% humidity for 14 days. Surface microhardness was measured, topographic changes were observed, and phase analysis was performed using X-ray diffraction. Microhardness according to storage conditions was compared using one-way analysis of variance and Tukey's multiple comparison tests (P < .05). Results: The BC and ES sealers exhibited decreased microhardness when stored in acid or PBS compared with control (P < .05). In the WR group, acid exposure lowered microhardness of the specimens compared with control (P < .05). Scanning electron microscopy revealed different topographies in specimens from all tested sealers exposed to acid or PBS. Conclusion: The surface microhardness of calcium silicate-based sealers was reduced by exposure to either acid or PBS. Acid solutions, however, had a more detrimental effect than PBS. PMID- 29576842 TI - Baseline Air Quality Assessment of Goods Movement Activities before the Port of Charleston Expansion: A Community-University Collaborative. AB - As the demand for goods continues to increase, a collective network of transportation systems is required to facilitate goods movement activities. This study examines air quality near the Port of Charleston before its expansion and briefly describes the establishment and structure of a community-university partnership used to monitor existing pollution. Particulate matter (PM) concentrations (PM2.5 and PM10) were measured using the Thermo Fisher Scientific Partisol 2000i-D Dichotomous Air Sampler, Thermo Scientific Dichotomous Sequential Air Sampler Partisol-Plus 2025-D, and Rupprecht & Patashnick TEOM Series 1400 Sampler at neighborhood (Union Heights, Rosemont, and Accabee) and reference (FAA2.5 and Jenkins Street) sites. Descriptive statistics were performed and an ANOVA (analysis of variance) was calculated to find the difference in overall mean 24-hour PM average concentrations in communities impacted by environmental injustice. PM2.5 (15.2 MUg/m3) and PM10 (27.2 MUg/m3) maximum concentrations were highest in neighborhoods such as Union Heights neighborhoods due to more goods movement activities. Nevertheless, there was no statistically significant difference in mean concentrations of PM2.5 and PM10 across neighborhood sites. In contrast, mean PM10 neighborhood concentrations were significantly lower than mean PM10 reference concentrations for Union Heights (p = 0.00), Accabee (p <= 0.0001), and Rosemont (p = 0.01). Although PM concentrations were lower than current National Ambient Air Quality Standards, this study demonstrated how community-university partners can work collectively to document baseline PM concentrations that will be used to examine changes in air quality after the port expansion brings additional goods movement activities to the area.

PMID- 29576843 TI - Modulation of Adipocyte Differentiation and Proadipogenic Gene Expression by Sulforaphane, Genistein, and Docosahexaenoic Acid as a First Step to Counteract Obesity. AB - Obesity is characterized by excess body fat accumulation due to an increase in the size and number of differentiated mature adipocytes. Adipocyte differentiation is regulated by genetic and environmental factors, and its inhibition could represent a strategy for obesity prevention and treatment. The current study was designed with two aims: (i) to evaluate the changes in the expression of adipogenic markers (C/EBPalpha, PPARgamma variant 1 and variant 2, and GLUT4) in 3T3-L1 murine preadipocytes at four stages of the differentiation process and (ii) to compare the effectiveness of sulforaphane, genistein, and docosahexaenoic acid in reducing lipid accumulation and modulating C/EBPalpha, PPARgamma1, PPARgamma2, and GLUT4 mRNA expression in mature adipocytes. All bioactive compounds were shown to suppress adipocyte differentiation, although with different effectiveness. These results set the stage for further studies considering natural food constituents as important agents in preventing or treating obesity. PMID- 29576845 TI - Immunomodulatory Effects of Diterpene Quinone Derivatives from the Roots of Horminum pyrenaicum in Human PBMC. AB - Several phytochemicals were shown to interfere with redox biology in the human system. Moreover, redox biochemistry is crucially involved in the orchestration of immunological cascades. When screening for immunomodulatory compounds, the two interferon gamma- (IFN-gamma-) dependent immunometabolic pathways of tryptophan breakdown via indoleamine 2,3-dioxygenase-1 (IDO-1) and neopterin formation by GTP-cyclohydrolase 1 (GTP-CH-I) represent prominent targets, as IFN-gamma-related signaling is strongly sensitive to oxidative triggers. Herein, the analysis of these pathway activities in human peripheral mononuclear cells was successfully applied in a bioactivity-guided fractionation strategy to screen for anti inflammatory substances contained in the root of Horminum (H.) pyrenaicum L. (syn. Dragon's mouth), the only representative of the monophyletic genus Horminum. Four abietane diterpene quinone derivatives (horminone, 7-O acetylhorminone, inuroyleanol and its 15,16-dehydro-derivative, a novel natural product), two nor-abietane diterpene quinones (agastaquinone and 3 deoxyagastaquinone) and two abeo 18 (4 -> 3) abietane diterpene quinones (agastol and its 15,16-dehydro-derivative) could be identified. These compounds were able to dose-dependently suppress the above mentioned pathways with different potency. Beside the description of new active compounds, this study demonstrates the feasibility of integrating IDO-1 and GTP-CH-I activity in the search for novel anti-inflammatory compounds, which can then be directed towards a more detailed mode of action analysis. PMID- 29576846 TI - Proscillaridin A Promotes Oxidative Stress and ER Stress, Inhibits STAT3 Activation, and Induces Apoptosis in A549 Lung Adenocarcinoma Cells. AB - Cardiac glycosides are natural compounds used for the treatment of cardiovascular disorders. Although originally prescribed for cardiovascular diseases, more recently, they have been rediscovered for their potential use in the treatment of cancer. Proscillaridin A (PSD-A), a cardiac glycoside component of Urginea maritima, has been reported to exhibit anticancer activity. However, the cellular targets and anticancer mechanism of PSD-A in various cancers including lung cancer remain largely unexplored. In the present study, we found that PSD-A inhibits growth and induces apoptosis in A549 lung adenocarcinoma cells. The anticancer activity of PSD-A was found to be associated with the activation of JNK, induction of ER stress, mitochondrial dysfunction, and inhibition of STAT3 activation. PSD-A induces oxidative stress as evidenced from ROS generation, GSH depletion, and decreased activity of TrxR1. PSD-A-mediated ER stress was verified by increased phosphorylation of eIF2alpha and expression of its downstream effector proteins ATF4, CHOP, and caspases-4. PSD-A triggered apoptosis by inducing JNK (1/2) activation, increasing bax/bcl-2 ratio, dissipating mitochondrial membrane potential, and inducing cleavage of caspases and PARP. Further study revealed that PSD-A inhibits both constitutive and inducible STAT3 activations and decreases STAT3 DNA-binding activity. Moreover, PSD-A-mediated inhibition of STAT3 activation was found to be associated with increased SHP-1 expression, decreased phosphorylation of Src, and binding of PSD-A with STAT3 SH2 domain. Finally, STAT3 knockdown by shRNA inhibited growth and enhanced apoptotic efficacy of PSD-A. Taken together, the data suggest that PSD-A could be developed into a potential therapeutic agent against lung adenocarcinoma. PMID- 29576847 TI - Differentiation of Promonocytic U937 Cells to Monocytes Is Associated with Reduced Mitochondrial Transport of Ascorbic Acid. AB - Growth of promonocytic U937 cells in the presence of DMSO promotes their differentiation to monocytes. After 4 days of culture in differentiating medium, these cells ceased to proliferate, displayed downregulated ryanodine receptor expression, and responded to specific stimuli with enhanced NADPH-oxidase-derived superoxide formation or cytosolic phospholipase A2-dependent arachidonic acid release. We found that the 4-day differentiation process is also associated with downregulated SVCT2 mRNA expression, in the absence of apparent changes in SVCT2 protein expression and transport rate of ascorbic acid (AA). Interestingly, under the same conditions, these cells accumulated lower amounts of the vitamin in their mitochondria, with an ensuing reduced response to external stimuli sensitive to the mitochondrial fraction of AA. Further analyses demonstrated an unexpected increase in mitochondrial SVCT2 protein expression, however, associated with reduced SVCT2-dependent AA uptake in isolated mitochondria. A decrease in the transporter Vmax, with no change in affinity, was found to account for this response. Differentiation of promonocytic cells to monocytes is therefore characterized by decreased SVCT2 mRNA expression that, even prior to the onset of SVCT2 protein downregulation or apparent changes in plasma membrane transport activity, impacts on the mitochondrial accumulation of the vitamin through a decreased Vmax of the transporter. PMID- 29576848 TI - The Ratio of Plasma and Urinary 8-oxo-Gsn Could Be a Novel Evaluation Index for Patients with Chronic Kidney Disease. AB - Nucleic acid oxidation plays an important role in the pathophysiology progress of a variety of diseases. 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGsn) and 8-oxo 7,8-dihydroguanosine (8-oxo-Gsn), which originate from DNA and RNA oxidation, were the most widely used indicators for oxidative stress. The study investigated the relation between 8-oxo-dGsn, 8-oxo-Gsn, and CKD. 146 patients with CKD were divided into five disease stages, and their fasting blood and morning urine were collected. The levels of 8-oxo-dGsn and 8-oxo-Gsn in plasma and urine were quantified by LC-MS/MS. The ratio of urinary 8-oxo-Gsn to creatinine increased from stages 1 to 4 corresponding to the increased severity of CKD, but it decreased in stage 5. And plasma 8-oxo-Gsn gradually increased with the decline of renal function. In particular, the increased ratio of plasma and urine 8-oxo Gsn in stage 5 exceeded the concentration of creatinine. This trend was similar to the estimated glomerular filtration rate (eGFR), which indicates that 8-oxo Gsn could be an appropriate indicator for renal function. Our finding indicates that as the disease progresses, RNA oxidation is increased. The significant increase in the ratio of plasma and urinary 8-oxo-Gsn is a novel evaluation index of end-stage renal disease. PMID- 29576849 TI - Palmitoylethanolamide Dampens Reactive Astrogliosis and Improves Neuronal Trophic Support in a Triple Transgenic Model of Alzheimer's Disease: In Vitro and In Vivo Evidence. AB - Alzheimer's disease (AD) is a neurodegenerative disorder responsible for the majority of dementia cases in elderly people. It is widely accepted that the main hallmarks of AD are not only senile plaques and neurofibrillary tangles but also reactive astrogliosis, which often precedes detrimental deposits and neuronal atrophy. Such phenomenon facilitates the regeneration of neural networks; however, under some circumstances, like in AD, reactive astrogliosis is detrimental, depriving neurons of the homeostatic support, thus contributing to neuronal loss. We investigated the presence of reactive astrogliosis in 3*Tg-AD mice and the effects of palmitoylethanolamide (PEA), a well-documented anti inflammatory molecule, by in vitro and in vivo studies. In vitro results revealed a basal reactive state in primary cortical 3*Tg-AD-derived astrocytes and the ability of PEA to counteract such phenomenon and improve viability of 3*Tg-AD derived neurons. In vivo observations, performed using ultramicronized- (um-) PEA, a formulation endowed with best bioavailability, confirmed the efficacy of this compound. Moreover, the schedule of treatment, mimicking the clinic use (chronic daily administration), revealed its beneficial pharmacological properties in dampening reactive astrogliosis and promoting the glial neurosupportive function. Collectively, our results encourage further investigation on PEA effects, suggesting it as an alternative or adjunct treatment approach for innovative AD therapy. PMID- 29576850 TI - Transcriptome Remodeling of Differentiated Cells during Chronological Ageing of Yeast Colonies: New Insights into Metabolic Differentiation. AB - We present the spatiotemporal metabolic differentiation of yeast cell subpopulations from upper, lower, and margin regions of colonies of different ages, based on comprehensive transcriptomic analysis. Furthermore, the analysis was extended to include smaller cell subpopulations identified previously by microscopy within fully differentiated U and L cells of aged colonies. New data from RNA-seq provides both spatial and temporal information on cell metabolic reprogramming during colony ageing and shows that cells at marginal positions are similar to upper cells, but both these cell types are metabolically distinct from cells localized to lower colony regions. As colonies age, dramatic metabolic reprogramming occurs in cells of upper regions, while changes in margin and lower cells are less prominent. Interestingly, whereas clear expression differences were identified between two L cell subpopulations, U cells (which adopt metabolic profiles, similar to those of tumor cells) form a more homogeneous cell population. The data identified crucial metabolic reprogramming events that arise de novo during colony ageing and are linked to U and L cell colony differentiation and support a role for mitochondria in this differentiation process.

AB - RNA-binding protein dysregulation and altered expression of proteins involved in the autophagy/proteasome pathway play a role in many neurodegenerative disease onset/progression, including age-related macular degeneration (AMD). HuR/ELAVL1 is a master regulator of gene expression in human physiopathology. In ARPE-19 cells exposed to the proteasomal inhibitor MG132, HuR positively affects at posttranscriptional level p62 expression, a stress response gene involved in protein aggregate clearance with a role in AMD. Here, we studied the early effects of the proautophagy AICAR + MG132 cotreatment on the HuR-p62 pathway. We treated ARPE-19 cells with Erk1/2, AMPK, p38MAPK, PKC, and JNK kinase inhibitors in the presence of AICAR + MG132 and evaluated HuR localization/phosphorylation and p62 expression. Two-hour AICAR + MG132 induces both HuR cytoplasmic translocation and threonine phosphorylation via the Erk1/2 pathway. In these conditions, p62 mRNA is loaded on polysomes and its translation in de novo protein is favored. Additionally, for the first time, we report that JNK can phosphorylate HuR, however, without modulating its localization. Our study supports HuR's role as an upstream regulator of p62 expression in ARPE-19 cells, helps to understand better the early events in response to a proautophagy stimulus, and suggests that modulation of the autophagy-regulating kinases as potential therapeutic targets for AMD may be relevant. PMID- 29576852 TI - ZP2495 Protects against Myocardial Ischemia/Reperfusion Injury in Diabetic Mice through Improvement of Cardiac Metabolism and Mitochondrial Function: The Possible Involvement of AMPK-FoxO3a Signal Pathway. AB - Coronary heart disease patients with type 2 diabetes were subject to higher vulnerability for cardiac ischemia-reperfusion (I/R) injury. This study was designed to evaluate the impact of ZP2495 (a glucagon-GLP-1 dual-agonist) on cardiac function and energy metabolism after myocardial I/R injury in db/db mice with a focus on mitochondrial function. C57BLKS/J-lepr+/lepr+ (BKS) and db/db mice received 4-week treatment of glucagon, ZP131 (GLP-1 receptor agonist), or ZP2495, followed by cardiac I/R injury. The results showed that cardiac function, cardiac glucose metabolism, cardiomyocyte apoptosis, cardiac mitochondrial morphology, and energetic transition were improved or ameliorated by ZP2495 to a greater extent than that of glucagon and ZP131. In vitro study showed that ZP2495, rather than glucagon, alleviated mitochondrial depolarization, cytochrome C release, and mitochondria ROS generation in neonatal rat ventricular myocytes subjected to high-glucose and simulated I/R injury conditions, the effects of which were weaker in the ZP131 group. Furthermore, the expressions of Akt, FoxO3a, and AMPK phosphorylation were elevated by ZP2495 to a greater extent than that of ZP131. In conclusion, ZP2495 may contribute to the improvement of cardiac function and energy metabolism in db/db mice after myocardial I/R injury by improving mitochondrial function possibly through Akt/FoxO3a and AMPK/FoxO3a signal pathways. PMID- 29576853 TI - Quercetin Prevents Diastolic Dysfunction Induced by a High-Cholesterol Diet: Role of Oxidative Stress and Bioenergetics in Hyperglycemic Rats. AB - Alterations in cardiac energy metabolism play a key role in the pathogenesis of diabetic cardiomyopathy. Hypercholesterolemia associated with bioenergetic impairment and oxidative stress has not been well characterized in the cardiac function under glycemic control deficiency conditions. This work aimed to determine the cardioprotective effects of quercetin (QUE) against the damage induced by a high-cholesterol (HC) diet in hyperglycemic rats, addressing intracellular antioxidant mechanisms and bioenergetics. Quercetin reduced HC induced alterations in the lipid profile and glycemia in rats. In addition, QUE attenuated cardiac diastolic dysfunction (increased E:A ratio), prevented cardiac cholesterol accumulation, and reduced the increase in HC-induced myocyte density. Moreover, QUE reduced HC-induced oxidative stress by preventing the decrease in GSH/GSSG ratio, Nrf2 nuclear translocation, HO-1 expression, and antioxidant enzymatic activity. Quercetin also counteracted HC-induced bioenergetic impairment, preventing a reduction in ATP levels and alterations in PGC-1alpha, UCP2, and PPARgamma expression. In conclusion, the mechanisms that support the cardioprotective effect of QUE in rats with HC might be mediated by the upregulation of antioxidant mechanisms and improved bioenergetics on the heart. Targeting bioenergetics with QUE can be used as a pharmacological approach to modulate structural and functional changes of the heart under hypercholesterolemic and hyperglycemic conditions. PMID- 29576854 TI - Oxygen Concentration and Oxidative Stress Modulate the Influence of Alzheimer's Disease Abeta1-42 Peptide on Human Cells. AB - Reactive oxygen species (ROS) generated after exposure to ionizing radiation and toxic peptides, in mitochondrial metabolism and during aging contribute to damage of cell's structural and functional components and can lead to diseases. Monomers and small oligomers of amyloid beta (Abeta) peptide, players in Alzheimer's disease, are recently suggested to be involved in damaging of neurons, instead of extracellular Abeta plaques. We demonstrate that externally applied disaggregated Abeta1-42 peptide interacts preferentially with acidic compartments (lysosomes). We compared standard cell cultivation (21% O2) to more physiological cell cultivation (5% O2). Cells did not exhibit a dramatic increase in ROS and change in glutathione level upon 4 MUM Abeta peptide treatment, whereas exposure to 2 Gy X-rays increased ROS and changed glutathione level and ATP concentration. The occurrence of the 4977 bp deletion in mtDNA and significant protein carbonylation were specific effects of IR and more pronounced at 21% O2. An increase in cell death after Abeta peptide treatment or irradiation was unexpectedly restored to the control level or below when both were combined, particularly at 5% O2. Therefore, Abeta peptide at low concentration can trigger neuroprotective mechanisms in cells exposed to radiation. Oxygen concentration is an important modulator of cellular responses to stress. PMID- 29576855 TI - Tetrahydroxystilbene Glucoside Produces Neuroprotection against 6-OHDA-Induced Dopamine Neurotoxicity. AB - Parkinson's disease (PD) was one of the most common neurodegenerative diseases with a slow and progressive loss of dopamine (DA) neurons in the midbrain substantia nigra (SN). Neuroinflammation was identified to be an important contributor to PD pathogenesis with the hallmark of microglia activation. Tetrahydroxystilbene glucoside (TSG) was the main active component extracted from Polygonum multiflorum and held amounts of pharmacological activities including antioxidant, free radical-scavenging, anti-inflammation, and cardioprotective properties. Recent studies demonstrated that TSG exerted neuroprotection from several neurodegenerative disease models. However, the underlying mechanisms were not completely elucidated. In the present study, rat nigral stereotaxic injection of 6-hydroxydopamine- (6-OHDA-) elicited DA neuronal injury was performed to investigate TSG-mediated neuroprotection on DA neurons. In addition, primary rat midbrain neuron-glia cocultures were applied to explore the mechanisms underlying TSG-exerted neuroprotection. Results showed that daily intraperitoneal injection of TSG for 14 consecutive days significantly protected DA neurons from 6-OHDA induced neurotoxicity and suppressed microglia activation. Similar neuroprotection was shown in primary neuron-glia cocultures. In vitro studies further demonstrated that TSG inhibited microglia activation and subsequent release of proinflammatory factors. Moreover, TSG-mediated neuroprotection was closely related with the inactivation of mitogen-activated protein kinase (MAPK) signaling pathway. Together, TSG protects DA neurons from 6-OHDA-induced neurotoxicity via the inhibition of microglia-elicited neuroinflammation. These findings suggest that TSG might hold potential therapeutic effects on PD. PMID- 29576858 TI - Cardioprotective and Metabolomic Profiling of Selected Medicinal Plants against Oxidative Stress. AB - In this research work, the antioxidant and metabolomic profiling of seven selected medicinally important herbs including Rauvolfia serpentina, Terminalia arjuna, Coriandrum sativum, Elettaria cardamom, Piper nigrum, Allium sativum, and Crataegus oxyacantha was performed. The in vivo cardioprotective potential of these medicinal plants was evaluated against surgically induced oxidative stress through left anterior descending coronary artery ligation (LADCA) in dogs. The antioxidant profiling of these plants was done through DPPH and DNA protection assay. The C. oxyacantha and T. arjuna showed maximum antioxidant potential, while the E. cardamom showed poor antioxidative strength even at its high concentration. Different concentrations of extracts of the said plants exhibited the protection of plasmid DNA against H2O2 damage as compared to the plasmid DNA merely treated with H2O2. The metabolomic profiling through LC-MS analysis of these antioxidants revealed the presence of active secondary metabolites responsible for their antioxidant potential. During in vivo analysis, blood samples of all treatment groups were drawn at different time intervals to analyze the cardiac and hemodynamic parameters. The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs. PMID- 29576857 TI - Citrus aurantium Naringenin Prevents Osteosarcoma Progression and Recurrence in the Patients Who Underwent Osteosarcoma Surgery by Improving Antioxidant Capability. AB - Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS). Three main components (naringin, naringenin, and hesperetin) were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n = 47) and control group (CG, received 20 mg placebo daily, n = 48). After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P > 0.01). The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability. PMID- 29576860 TI - Preoperative short-course radiotherapy in rectal cancer patients: results and prognostic factors. AB - Objective: The purpose of this study was to evaluate the clinical outcome of preoperative short-course radiotherapy for rectal cancer patients. Methods: The study group comprised 210 patients with pathologically proven resectable rectal cancer. Between 2001 and 2013, they were treated preoperatively with short-course radiotherapy (25 Gy delivered in five fractions), followed by total mesorectal excision. Adjuvant 5-fluorouracil-based chemotherapy was administered at the discretion of the treating physician, depending on the pathological stage. Results: After a median follow-up of 57 months, the following 5-year survival rates were observed: overall survival-66.4%, disease-free survival-67.2%, locoregional relapse-free survival-91.7%, and distant metastases-free survival 71.5%. The local failure was observed in 15 patients. Ten patients (4.8%) achieved pathologic complete response. The multivariate analysis demonstrated the regional lymph node involvement to be statistically significant for unfavorable outcomes in terms of all estimated survival rates. Lymphovascular invasion was found to be a strong predictor of survival (HR = 1.68; 95% CI 1.29-3.55) and treatment failure (HR = 1.54; 95% CI 1.08-3.34). The presence of positive surgical circumferential margin was related to six times higher risk of locoregional recurrence. Early and late severe treatment-induced toxicity was reported in 1 and 7.6% patients, respectively. Conclusions: Preoperative short course radiotherapy followed by total mesorectal excision and adjuvant chemotherapy allows to achieve excellent local control and favorable survival rates. The treatment-induced toxicity is acceptable. PMID- 29576861 TI - A Subband-Specific Deconvolution Model for MTF Improvement in CT. AB - The purpose of this research is to achieve uniform spatial resolution in CT (computed tomography) images without hardware modification. The main idea of this study is to consider geometry optics model, which can provide the approximate blurring PSF (point spread function) kernel, which varies according to the distance from X-ray tube to each pixel. The FOV (field of view) was divided into several band regions based on the distance from X-ray source, and each region was deconvolved with different deconvolution kernels. Though more precise calculation for the PSF for deconvolution is possible as the number of subbands increases, we set the number of subbands to 11. 11 subband settings seem to be a balancing point to reduce noise boost, while MTF (modulation transfer function) increase still remains. As the results show, subband-wise deconvolution makes image resolution (in terms of MTF) relatively uniform across the FOV. The results show that spatial resolution in CT images can be uniform across the FOV without using additional equipment. The beauty of this method is that it can be applied to any CT system as long as we know the specific system parameters and determine the appropriate PSF for deconvolution maps of the system. The proposed algorithm shows promising result in improving spatial resolution uniformity while avoiding the excessive noise boost. PMID- 29576856 TI - Macroautophagy and Chaperone-Mediated Autophagy in Heart Failure: The Known and the Unknown. AB - Cardiac diseases including hypertrophic and ischemic cardiomyopathies are increasingly being reported to accumulate misfolded proteins and damaged organelles. These findings have led to an increasing interest in protein degradation pathways, like autophagy, which are essential not only for normal protein turnover but also in the removal of misfolded and damaged proteins. Emerging evidence suggests a previously unprecedented role for autophagic processes in cardiac physiology and pathology. This review focuses on the major types of autophagic processes, the genes and protein complexes involved, and their regulation. It discusses the key similarities and differences between macroautophagy, chaperone-mediated autophagy, and selective mitophagy structures and functions. The genetic models available to study loss and gain of macroautophagy, mitophagy, and CMA are discussed. It defines the markers of autophagic processes, methods for measuring autophagic activities, and their interpretations. This review then summarizes the major studies of autophagy in the heart and their contribution to cardiac pathology. Some reports suggest macroautophagy imparts cardioprotection from heart failure pathology. Meanwhile, other studies find macroautophagy activation may be detrimental in cardiac pathology. An improved understanding of autophagic processes and their regulation may lead to a new genre of treatments for cardiac diseases. PMID- 29576859 TI - Effectiveness and toxicity of conventional radiotherapy treatment for painful spinal metastases: a detailed course of side effects after opposing fields versus a single posterior field technique. AB - Background: Conventional radiotherapy for painful spinal metastases can be delivered with a single posterior-anterior (PA) or two opposed anterior-posterior (APPA) fields. We studied the effectiveness and toxicity of both techniques and studied whether treatment technique was predictive for abdominal and skin toxicity. Patients and methods: Within the Dutch Bone Metastasis Study, 343 patients received 8 Gray in a single fraction or 24 Gray in six fractions for painful spinal metastases. Treatment technique was not randomized. At baseline and weekly during follow-up, patients reported pain and other physical complaints. Any complaint increasing within 4 weeks after treatment was noted as a side effect. Pain response was calculated according to international standards, taking into account changes in pain score and medication. Repeated measurement analyses and multivariate logistic analyses were performed. Results: Patients were mainly treated on the thoracic (34%) and lumbar (53%) spine and 73% received a PA field. Pain response was similar between both techniques (74%). In patients treated at the thoraco-lumbar and lumbar spine, with multiple fractions, significantly more abdominal complaints were noticed. In multivariate analysis, radiotherapy technique did not predict for side effects. Conclusion: Conventional radiotherapy of painful spinal metastases provides limited toxicity. Radiotherapy technique is not an independent predictor of abdominal and skin toxicity of irradiation. PMID- 29576862 TI - A method for analysing small samples of floral pollen for free and protein-bound amino acids. AB - Pollen provides floral visitors with essential nutrients including proteins, lipids, vitamins and minerals. As an important nutrient resource for pollinators, including honeybees and bumblebees, pollen quality is of growing interest in assessing available nutrition to foraging bees. To date, quantifying the protein bound amino acids in pollen has been difficult and methods rely on large amounts of pollen, typically more than 1 g. More usual is to estimate a crude protein value based on the nitrogen content of pollen, however, such methods provide no information on the distribution of essential and non-essential amino acids constituting the proteins.Here, we describe a method of microwave-assisted acid hydrolysis using low amounts of pollen that allows exploration of amino acid composition, quantified using ultra high performance liquid chromatography (UHPLC), and a back calculation to estimate the crude protein content of pollen.Reliable analysis of protein-bound and free amino acids as well as an estimation of crude protein concentration was obtained from pollen samples as low as 1 mg. Greater variation in both protein-bound and free amino acids was found in pollen sample sizes <1 mg. Due to the variability in recovery of amino acids in smaller sample sizes, we suggest a correction factor to apply to specific sample sizes of pollen in order to estimate total crude protein content.The method described in this paper will allow researchers to explore the composition of amino acids in pollen and will aid research assessing the available nutrition to pollinating animals. This method will be particularly useful in assaying the pollen of wild plants, from which it is difficult to obtain large sample weights. PMID- 29576863 TI - Curious case of a calcified food bolus. AB - Authors present an 80-year-old male attending with obstructive food bolus. Lateral soft tissue neck x-ray demonstrated a suspected calcified foreign body at the level of the larynx. Subsequent senior radiological input reported the findings as incidental calcification of carotid arteries. ENT surgeons should demonstrate increased awareness for potentially calcified soft tissues on interpreting such x-rays. PMID- 29576864 TI - Factors Influencing Maternal Behavioral Adaptability: Maternal Depressive Symptoms and Child Negative Affect. AB - In early childhood, parents play an important role in children's socioemotional development. As such, parent training is a central component of many psychological interventions for young children (Reyno & McGrath, 2006). Maternal depressive symptoms have consistently been linked to maladaptive parenting behaviors (e.g., disengagement, intrusiveness), as well as to lower parent training efficacy in the context of child psychological intervention, suggesting that mothers with higher symptomatology may be less able to be adapt their behavior according to situational demands. The goal of the current study was to examine both maternal and child factors that may influence maternal behavioral adaptability. Ninety-one mothers and their toddlers (M =23.93 months, 59% male) participated in a laboratory visit during which children engaged in a variety of novelty episodes designed to elicit individual differences in fear/withdrawal behaviors. Mothers also completed a questionnaire battery. Maternal behavioral adaptability was operationalized as the difference in scores for maternal involvement, comforting, and protective behavior between episodes in which mothers were instructed to refrain from interaction and those in which they were instructed to act naturally. Results indicated that when children displayed high levels of negative affect in the restricted episodes, mothers with higher levels of depressive symptoms were less able to adapt their involved behavior because they exhibited low rates of involvement across episodes regardless of instruction given. The current study serves as an intermediary step in understanding how maternal depressive symptoms may influence daily interactions with their children as well as treatment implementation and outcomes, and provides initial evidence that maternal internalizing symptoms may contribute to lower behavioral adaptability in the context of certain child behaviors due to consistent low involvement. PMID- 29560250 TI - exprso: an R-package for the rapid implementation of machine learning algorithms. AB - Machine learning plays a major role in many scientific investigations. However, non-expert programmers may struggle to implement the elaborate pipelines necessary to build highly accurate and generalizable models. We introduce exprso, a new R package that is an intuitive machine learning suite designed specifically for non-expert programmers. Built initially for the classification of high dimensional data, exprso uses an object-oriented framework to encapsulate a number of common analytical methods into a series of interchangeable modules. This includes modules for feature selection, classification, high-throughput parameter grid-searching, elaborate cross-validation schemes (e.g., Monte Carlo and nested cross-validation), ensemble classification, and prediction. In addition, exprso also supports multi-class classification (through the 1-vs-all generalization of binary classifiers) and the prediction of continuous outcomes. PMID- 29576865 TI - HCC with low- and normal-serum alpha-fetoprotein levels. AB - A large database of 1773 HCC patients in Turkey was examined. 41.9% had alpha fetoprotein (AFP) levels <20 IU/ml and an additional 16.123% had values between 20-100 IU/ml. This 58% of the cohort (<100 IU/ml AFP levels) was examined in detail. 66% of patients with small (<5 cm) HCCs had low AFP, compared to 49% of patients with larger (>5 cm) HCCs. The mean diameter (MTD) of larger MTD, low AFP tumors was 8.4cm. Therefore, factors other than AFP must contribute to HCC tumor growth. Larger tumors in low AFP patients had both higher platelet levels and increased PVT percent. Linear regression analysis for both MTD and multifocality showed that platelet numbers and presence of PVT were significant variables; whereas for PVT, significant variables were albumin, alkaline phosphatase and MTD. Comparisons between patients with AFP levels <20, 20-<100, 100-<1000 and >1000 IU/ml showed the most significant tumor finding was an increase in PVT percent between each group, and to a lesser extent, MTD. Thus, low- or normal-AFP HCCs constitute the majority of patients and have slightly lower MTD and much lower PVT percent than HCCs associated with elevated blood AFP levels. New, non AFP markers are thus needed, especially for small HCCs. PMID- 29568492 TI - Using regulatory genomics data to interpret the function of disease variants and prioritise genes from expression studies. AB - The identification of therapeutic targets is a critical step in the research and developement of new drugs, with several drug discovery programmes failing because of a weak linkage between target and disease. Genome-wide association studies and large-scale gene expression experiments are providing insights into the biology of several common diseases, but the complexity of transcriptional regulation mechanisms often limits our understanding of how genetic variation can influence changes in gene expression. Several initiatives in the field of regulatory genomics are aiming to close this gap by systematically identifying and cataloguing regulatory elements such as promoters and enhacers across different tissues and cell types. In this Bioconductor workflow, we will explore how different types of regulatory genomic data can be used for the functional interpretation of disease-associated variants and for the prioritisation of gene lists from gene expression experiments. PMID- 29576868 TI - A rare cause of primary adrenal insufficiency due to a homozygous Arg188Cys mutation in the STAR gene. AB - : Steroidogenic acute regulatory protein (STAR) is a key protein for the intracellular transport of cholesterol to the mitochondrium in endocrine organs (e.g. adrenal gland, ovaries, testes) and essential for the synthesis of all steroid hormones. Several mutations have been described and the clinical phenotype varies strongly and may be grouped into classic lipoid congenital adrenal hyperplasia (LCAH), in which all steroidogenesis is disrupted, and non classic LCAH, which resembles familial glucocorticoid deficiency (FGD), which affects predominantly adrenal functions. Classic LCAH is characterized by early and potentially life-threatening manifestation of primary adrenal insufficiency (PAI) with electrolyte disturbances and 46,XY disorder of sex development (DSD) in males as well as lack of pubertal development in both sexes. Non-classic LCAH manifests usually later in life with PAI. Nevertheless, life-long follow-up of gonadal function is warranted. We describe a 26-year-old female patient who was diagnosed with PAI early in life without detailed diagnostic work-up. At the age of 14 months, she presented with hyperpigmentation, elevated ACTH and low cortisol levels. As her older brother was diagnosed with PAI two years earlier, she was put on hydrocortisone and fludrocortisone replacement therapy before an Addisonian crisis occurred. Upon review of her case in adulthood, consanguinity was noted in the family. Genetic analysis for PAI revealed a homozygous mutation in the STAR gene (c.562C>T, p.Arg188Cys) in both siblings. This mutation has been previously described in non-classic LCAH. This case illustrates that early onset, familial PAI is likely due to autosomal recessive genetic mutations in known genes causing PAI. Learning points: In childhood-onset PAI, a genetic cause is most likely, especially in families with consanguinity.Adult patients with an etiologically unsolved PAI should be reviewed repeatedly and genetic work-up should be considered.Knowing the exact genetic diagnosis in PAI is essential for genetic counselling and may allow disease-specific treatment.Young men and women with NCLAH due to homozygous STAR Arg188Cys mutation should be investigated for their gonadal function as hypogonadism and infertility might occur during puberty or in early adulthood. PMID- 29576869 TI - Low carbohydrate diet and improved glycaemic control in a patient with type one diabetes. AB - : We present the case of an adult female with type 1 diabetes, whose HbA1c was trending at 58 mmol/mol (7.5%) for the past 3 years. In August 2016, she reduced her total daily carbohydrate intake to 30-50 g and adjusted her other macronutrients to compensate for the calorific deficit. Her HbA1c fell to 34 mmol/mol (5.3%) by January 2017 and average daily blood glucose readings decreased significantly from 10.4 to 6.1 mmol/L. Moreover, she observed a marked reduction of average daily glucose variability. Notably, there were no significant episodes of hypo- or hyperglycaemia and her lipid profile remained static. Subjectively, she described an improvement in her quality of life and the dietary transition was extremely well tolerated. We discuss these findings in detail and the potential clinical benefits for patients with type 1 diabetes that can be gained by following a low carbohydrate diet. Learning points: A low carbohydrate diet was found to substantially reduce HbA1c values and blood glucose (BG) variability, as well as causing a significant reduction in average daily glucose values in a patient with T1DM.Although further research is warranted, low carbohydrate diets in patients with T1DM have the potential to positively impact long-term morbidity and mortality through reduction of BG variability and average daily BG values.The diet was well tolerated and not associated with any adverse effects within this study. PMID- 29576870 TI - Nivolumab-induced fulminant diabetic ketoacidosis followed by thyroiditis. AB - : Five days following the 3rd cycle of nivolumab, a monoclonal antibody, which acts as immune checkpoint inhibitor against the programmed cell death protein-1, for metastatic lung adenocarcinoma, a 56-year-old woman presented at the hospital critically ill. On admission, she had severe diabetic ketoacidosis (DKA), as evidenced by venous glucose of 47 mmol/L, blood ketones of 7.5 mmol/L, pH of 6.95 and bicarbonate of 6.6 mmol/L. She has had no personal or family history of diabetes mellitus (DM), while random venous glucose, measured 1 week prior to hospitalisation, was 6.1 mmol/L. On admission, her HbA1c was 8.2% and anti-GAD antibodies were 12 kIU/L (0-5 kU/L), while islet cell antibodies and serum C peptide were undetectable. Nivolumab was recommenced without the development of other immune-mediated phenomena until 6 months later, when she developed hypothyroidism with TSH 18 U/L and low free T4. She remains insulin dependent and has required levothyroxine replacement, while she has maintained good radiological and clinical response to immunotherapy. This case is notable for the rapidity of onset and profound nature of DKA at presentation, which occurred two months following commencement of immunotherapy. Despite the association of nivolumab with immune-mediated endocrinopathies, only a very small number of patients developing type 1 DM has been reported to date. Patients should be closely monitored for hyperglycaemia and thyroid dysfunction prior to and periodically during immunotherapy. Learning points: Nivolumab can induce fulminant type 1 diabetes, resulting in DKA.Nivolumab is frequently associated with thyroid dysfunction, mostly hypothyroidism.Nivolumab-treated patients should be monitored regularly for hyperglycaemia and thyroid dysfunction.Clinicians should be aware and warn patients of potential signs and symptoms of severe hyperglycaemia. PMID- 29576871 TI - De novo HNF1 homeobox B mutation as a cause for chronic, treatment-resistant hypomagnesaemia. AB - : 29-year-old female presenting with an 8-year history of unexplained hypomagnesaemia, which was severe enough to warrant intermittent inpatient admission for intravenous magnesium. Urinary magnesium was inappropriately normal in the context of hypomagnesaemia indicating magnesium wasting. Ultrasound imaging demonstrated unilateral renal cysts and computed tomography of kidneys, ureters and bladder showed a bicornuate uterus. Referral to genetic services and subsequent testing revealed a de novo HNF1B deletion. Learning points: HNF1B loss of-function mutations are one of the most common monogenic causes of congenital anomalies of the kidney and urinary tract.Those with HNF1B mutations may have some of a constellation of features (renal and hepatic cysts, deranged liver function tests, maturity onset diabetes of the young type 5 (MODY5), bicornuate uterus, hyperparathyroidism, hyperuricaemic gout, but presenting features are highly heterogeneous amongst patients and no genotype/phenotype correlation exists. HNF1B mutations are inherited in an autosomal dominant pattern but up to 50% of cases are de novo.HNF1B mutations can be part of the Chr17q12 deletion syndrome, a contiguous gene deletion syndrome.Inorganic oral magnesium replacements are generally poorly tolerated with side effects of diarrhoea. Organic magnesium compounds, such as magnesium aspartate, are better absorbed oral replacement therapies. PMID- 29576872 TI - PFO closure in high-risk patient with paradoxical arterial embolism, deep vein thrombosis, pulmonary embolism and factor V Leiden genetic mutation. AB - Occurrence of paradoxical arterial embolism may cause the first symptoms in patients with a coexisting hypercoagulable state and patent foramen ovale (PFO). This can result in significant morbidity and mortality depending on the location of the embolism. The risks and benefits of closure of small PFOs have not been well elucidated in prior studies. We describe a patient with a history of Factor V Leiden heterozygosity who presented with left arm pain secondary to arterial embolism. The patient was a 51-year-old male who initially presented to the emergency department after awaking from sleep with progressive, severe, burning left arm pain. He had also noted intermittent shortness of breath over the 2 weeks prior to admission. Temperature was 97.4 F, pulse 86, respiratory rate 20 and blood pressure 121/87. Oxygen saturation was 94% on supplemental oxygen. He had a cool left upper extremity and the patient described subjective paresthesias in this extremity. Left radial pulse was difficult to palpate. Physical exam was otherwise unremarkable. Troponin I was mildly elevated at 0.217 ng/l. White blood cell count was 11.8 and INR 1.1. EKG showed sinus tachycardia with non-specific T abnormalities in the anterior leads. His past medical history was notable for only hypertension and hyperlipidemia. Current recommendation is for antiplatelet or anticoagulation for those with hypercoaguable states who suffer a stroke; there is currently no absolute indication for closure device. We describe the case of a 51-year-old male who had presented with left arm pain and shortness of breath. The computed tomography (CT) angiography of chest showed pulmonary emboli with heavy clot burden bilaterally. Heparin was started, but patient was found to have occlusion along large arteries of the left arm. Emergent left axillary, brachial, radial and ulnar embolectomy for acute critical arm ischemia were performed. The transthoracic echocardiogram done the next day with bubble study was positive for patent foramen ovale. Hypercoaguability showed factor V Leiden heterozygosity. Decision was made for the patient to initiate long-term anticoagulation with rivaroxaban and closure was performed. Patient was advised that closure is off label but opted to proceed with closure in light of hypercoaguable state. PMID- 29576873 TI - Systematic review of innovation design contests for health: spurring innovation and mass engagement. AB - We undertook a systematic review evaluating the effectiveness and cost of health focused innovation design contests. We followed Cochrane guidance and systematically searched eight databases. Articles were included if they reported an open contest focused on improving health, required participants submit finished design solutions and contained a prize structure. We searched 3579 citations, identifying 29 health-focused innovation design contests which collectively received 15494 contest submissions. Contests solicited submissions worldwide (7) and exclusively from North America (13), Asia (4), Africa (2), Australia (2) and Europe (1). Submissions per contest ranged from 3 to 11354 (median of 73). Contest entrants were tasked with helping develop health promotion messages (HPM) (25) and improve predictive clinical models, protocols and/or algorithms (4). Two types of contests emerged-those focused on high quality, innovative outcomes and those focused on the process of mass community engagement. All outcome-oriented contests had innovation design contest solutions equivalent or superior to the comparator (100%; 7/7). Two of two studies found that innovation design contests saved money (100%; 2/2). Five of seven process oriented contests concluded the contest improved at least one health indicator (71%; 5/7). Innovation design contests are an effective way to solicit innovative solutions to health problems and spur mass community engagement.

AB - To understand mental self-government of the developing reading and writing brain, correlations of clustering coefficients on fMRI reading or writing tasks with BASC 2 Adaptivity ratings (time 1 only) or working memory components (time 1 before and time 2 after instruction previously shown to improve achievement and change magnitude of fMRI connectivity) were investigated in 39 students in grades 4 to 9 who varied along a continuum of reading and writing skills. A Philips 3T scanner measured connectivity during six leveled fMRI reading tasks (subword letters and sounds, word-word-specific spellings or affixed words, syntax comprehension-with and without homonym foils or with and without affix foils, and text comprehension) and three fMRI writing tasks-writing next letter in alphabet, adding missing letter in word spelling, and planning for composing. The Brain Connectivity Toolbox generated clustering coefficients based on the cingulo opercular (CO) network; after controlling for multiple comparisons and movement, significant fMRI connectivity clustering coefficients for CO were identified in 8 brain regions bilaterally (cingulate gyrus, superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus, superior temporal gyrus, insula, cingulum cingulate gyrus, and cingulum-hippocampus). BASC2 Parent Ratings for Adaptivity were correlated with CO clustering coefficients on three reading tasks (letter sound, word affix judgments and sentence comprehension) and one writing task (writing next letter in alphabet). Before instruction, each behavioral working memory measure (phonology, orthography, morphology, and syntax coding, phonological and orthographic loops for integrating internal language and output codes, and supervisory focused and switching attention) correlated significantly with at least one CO clustering coefficient. After instruction, the patterning of correlations changed with new correlations emerging. Results show that the reading and writing brain's mental government, supported by both CO Adaptive Control and multiple working memory components, had changed in response to instruction during middle childhood/early adolescence. PMID- 29576876 TI - Corneal Biomechanical Properties after FS-LASIK with Residual Bed Thickness Less Than 50% of the Original Corneal Thickness. AB - Background: The changes in corneal biomechanical properties after LASIK remain an unknown but important topic for surgical design and prognostic evaluation. This study aims to observe the postoperative corneal biomechanical properties one month after LASIK with amount of corneal cutting (ACC) greater than 50% of the central corneal thickness (CCT). Methods: FS-LASIK was performed in 10 left rabbit eyes with ACC being 60% (L60) and 65% (L65) of the CCT, while the right eyes (R) were the control. After 4 weeks, rabbits were executed and corneal strip samples were prepared for uniaxial tensile tests. Results: At the same strain, the stresses of L65 and L60 were larger than those of R. The elastic moduli of L60 and L65 were larger than those of R when the stress was 0.02 MPa, while they began to be less than those of R when stress exceeds the low-stress region. After 10 s relaxation, the stress of specimens L65, L60, and R increased in turn. Conclusion: The elastic moduli of the cornea after FS-LASIK with ACC greater than 50% of the CCT do not become less under normal rabbit IOP. The limit stress grows with the rise of ACC when relaxation becomes stable. PMID- 29576877 TI - Effect of Hemodialysis on Eye Coats, Axial Length, and Ocular Perfusion Pressure in Patients with Chronic Renal Failure. AB - Purpose: To investigate changes in eye coats, axial length, and ocular perfusion pressure (OPP) in hemodialysis (HD) patients with chronic renal failure (CRF). Methods: We included HD patients who were diagnosed with CRF in our hospital from January to December 2015. Fifty-two patients met the inclusion criteria; all right eyes were used for observation. Systolic and diastolic blood pressures were recorded to calculate OPP. Approximately 30 minutes before and after HD, we recorded multiple parameters, including lens thickness (LT), axial length of vitreous (VAL), axial length of eye (EAL), ciliary body thickness (CBT), choroidal thickness (CT), and retinal thickness (RT). Results: After HD, OPP significantly decreased (P < 0.01, F = 7.023) and CBT became significantly thinner (P < 0.01, t = 3.461). CT was significantly thinner and differed among measurement locations (P < 0.01, t = 6.240; P < 0.01, t = 6.169; P < 0.01, t = 3.405, respectively, fovea, nasal, and temporal side 1500 MUm beside the fovea). Further, RT thickened and differed among measurement locations (P < 0.05, t = 2.265; P < 0.05, t = -2.624; P < 0.05, t = -2.220, respectively, fovea, nasal, and temporal side 1500 MUm beside fovea), whereas LT, VAL, and EAL significantly increased after HD (P < 0.05, t = -2.076; P < 0.01, t = -3.817; P < 0.01, t = 4.010). Conclusions: HD impacts the thickness of the eye coats and VAL, particularly affecting CBT, CT, and RT. OPP transiently decreases during HD, which may contribute to an ischemic state. PMID- 29576875 TI - Current Advances in Pharmacotherapy and Technology for Diabetic Retinopathy: A Systematic Review. AB - Diabetic retinopathy (DR) is classically defined by its vascular lesions and damage in the neurons of the retina. The cellular and clinical elements of DR have many features of chronic inflammation. Understanding the individual cell specific inflammatory changes in the retina may lead to novel therapeutic approaches to prevent vision loss. The systematic use of available pharmacotherapy has been reported as a useful adjunct tool to laser photocoagulation, a gold standard therapy for DR. Direct injections or intravitreal anti-inflammatory and antiangiogenesis agents are widely used pharmacotherapy to effectively treat DR and diabetic macular edema (DME). However, their effectiveness is short term, and the delivery system is often associated with adverse effects, such as cataract and increased intraocular pressure. Further, systemic agents (particularly hypoglycemic, hypolipidemic, and antihypertensive agents) and plants-based drugs have also provided promising treatment in the progression of DR. Recently, advancements in pluripotent stem cells technology enable restoration of retinal functionalities after transplantation of these cells into animals with retinal degeneration. This review paper summarizes the developments in the current and potential pharmacotherapy and therapeutic technology of DR. Literature search was done on online databases, PubMed, Google Scholar, clinitrials.gov, and browsing through individual ophthalmology journals and leading pharmaceutical company websites. PMID- 29576879 TI - The Balance of Th1/Th2 and LAP+Tregs/Th17 Cells Is Crucial for Graft Survival in Allogeneic Corneal Transplantation. AB - Purpose: CD4+LAP+ T cells are newly discovered regulatory T cells (Tregs). The aim of this study is to investigate the balance of Th1/Th2 and LAP+Tregs/Th17 in mice after allogeneic corneal transplantation. Methods: A total of 65 mice received orthotopic penetrating transplantation. According to the survival scores of the grafts, the mice were divided into the rejection group and the survival group 3 weeks after transplantation. Th1, Th2, Th17, and regulatory T cells in the ipsilateral drainage lymph nodes and spleens were measured with flow cytometry. The related cytokines in aqueous humor were also analyzed. Results: The frequencies of Foxp3+Tregs, GARP+Tregs, and LAP+Tregs in the survival group were significantly higher than those in the rejection group. And the expression trend of CD4+LAP+ T cells and CD4+GARP+ T cells was consistent. The level of IFN gamma, TNF, IL-6, and IL-17A markedly increased in aqueous humor during corneal allograft rejection. The ratio of Th1/Th2 and Th17/LAP+Tregs significantly increased in the rejection group at the 3rd week after corneal transplantation. Conclusion: LAP+Tregs might be regarded as substitute for Foxp3+Tregs. The balance of Th1/Th2 and LAP+Tregs/Th17 is crucial for corneal allograft survival. PMID- 29576878 TI - Early Intervention and Nonpharmacological Therapy of Myopia in Young Adults. AB - Myopia is a condition of the eye where parallel rays focus in front of, instead of on, the retina, which results in excessive refractive power of the cornea or the lens or eyeball elongation. Studies carried out in recent years show that the etiology of myopia is complex with genetic and environmental factors playing a role. Refraction defects decrease the quality of vision, while progressing myopia can lead to partial loss of vision, which can be particularly dramatic in young adults. Therefore, it is so crucial to take appropriate actions aimed at preventing myopia progression. This is a review of nonpharmacological therapeutic possibilities of refraction defect prevention in young adults, with special regard to myofascial therapy, osteopathy, and massage of acupuncture points surrounding the eye. PMID- 29576880 TI - Three-Year Outcomes of Cross-Linking PLUS (Combined Cross-Linking with Femtosecond Laser Intracorneal Ring Segments Implantation) for Management of Keratoconus. AB - Purpose: To analyze the results of three-year outcomes of combined epithelium-on cross-linking with femtosecond laser ICRS (cross-linking PLUS) for keratoconus management. Design: A retrospective multicenter clinical study. Methods: 43 eyes of 38 patients were subjected to preoperative and postoperative UCVA, BCVA, refraction, Pentacam pachymetry, and keratometry examinations at 3-, 6-, 12-, 24 , and 36-month follow-up period. Results: The preoperative and postoperative mean UCVA was 1.30 +/- 0.48 (logMAR +/- SD) and 0.82 +/- 0.22 respectively. The preoperative and postoperative mean BCVA was 0.90 +/- 0.40 and 0.60 +/- 0.30, respectively. The preoperative and postoperative mean K average was 50.63 +/- 0.87 (D +/- SD) and 45.56 +/- 0.98, respectively. The preoperative and postoperative mean pachymetry was 471 +/- 92.36 (MUm +/- SD) and 423 +/- 39.58, respectively. The preoperative and postoperative mean astigmatism was 7.55 +/- 1.75 and 3.39 +/- 1.26, respectively. One eye showed ICRS edge exposure while 6 eyes showed progression of keratoconus. Conclusion: CXL PLUS was proved to be a successful procedure to halt progression (mainly by CXL) and to correct the refractive status of the keratoconic eye (mainly by ICRS). CXL PLUS performed a synergistic action correcting and maintaining the correction of both myopic and astigmatic components of keratoconus. PMID- 29576881 TI - Combined Phacoemulsification and Goniosynechialysis under an Endoscope for Chronic Primary Angle-Closure Glaucoma. AB - Purpose: To investigate the clinical efficacy and safety of combined phacoemulsification with goniosynechialysis (GSL) under an ophthalmic endoscope for chronic primary angle-closure glaucoma and coexisting cataract. Methods: This is a retrospective study. The intraocular pressure (IOP), best-corrected visual acuity (BCVA), and number of glaucoma medications at baseline and each postoperative follow-up visit were recorded. Other measurements included supraciliochoroidal fluid measured by anterior segment optical coherence tomography, corneal endothelial cell density (ECD), and peripheral anterior synechia (PAS). All patients were followed for more than a year. Results: Thirty eight eyes of 31 patients were included. The mean follow-up duration was 16.3 +/- 3.9 months. The IOP decreased from 22.2 +/- 9.3 mmHg at baseline to 15.4 +/- 4.2 mmHg at the last follow-up (P < 0.001). The mean number of glaucoma medications (0.1 +/- 0.6) at the last follow-up was significantly lower than the preoperative number (2.3 +/- 1.1) (P < 0.001). All patients achieved improved or stable visual acuity after surgery. All patients achieved a complete opened angle after GSL. The postoperative complications included hyphema (7.9%), exudation (5.3%), transiently elevated IOP (55.3%), and supraciliochoroidal fluid (40%). Conclusions: Combined phacoemulsification and GSL under an endoscope can completely reopen PAS and is an effective and safe method for patients with chronic primary angle-closure glaucoma and coexisting cataract. PMID- 29576882 TI - Effect of Atropine Eye Drops on Choroidal Thinning Induced by Hyperopic Retinal Defocus. AB - Purpose: To investigate the effects of atropine on choroidal thinning induced by hyperopic retinal defocus. Methods: Ten young adults with myopia (-1.00 D to 5.00 D) viewed a video at 6 metres for 60 minutes on successive days. On day 1, one eye (control) was distance corrected with a contact lens; the other (experimental) eye wore a contact lens imposing 2.00 D of hyperopic retinal defocus. Sub- and perifoveal choroidal thickness (SFCT, PFCT) were monitored with optical coherence tomography. On day 2, the procedure was repeated but the experimental eye had received one drop of 0.5% atropine 22 hours earlier. Results: On day 1, eyes exposed to hyperopic defocus developed progressively thinner choroids (SFCT (baseline) = 253 +/- 32 MUm versus SFCT (40 mins) = 244 +/ 31 MUm, p = 0.004), whereas SFCT and PFCT in control eyes did not change (p > 0.17). On day 2 (22 hours after instilling atropine), baseline SFCT and PFCT were not different to day 1 (p > 0.05) and hyperopic defocus failed to thin the choroid (max change in SFCT = +2 +/- 2 MUm, p = 0.36). Conclusions: Atropine abolished choroidal thinning induced by hyperopic defocus without changing baseline choroidal thickness. The results suggest that atropine inhibits signals associated with hyperopic defocus, for example, from lag of accommodation during near work. This trial is registered with ACTRN12617001519347. PMID- 29576883 TI - Rate of Clinical Complete Response for 1 Year or More in Bone-Metastatic Breast Cancer after Comprehensive Treatments including Autologous Formalin-Fixed Tumor Vaccine. AB - Introduction: No effective treatment has been developed for bone-metastatic breast cancer. We found 3 cases with clinical complete response (cCR) of the bone metastasis and longer overall survival of the retrospectively examined cohort treated comprehensively including autologous formalin-fixed tumor vaccine (AFTV). Patients and Methods: AFTV was prepared individually for each patient from their own formalin-fixed and paraffin-embedded breast cancer tissues. Results: Three patients maintained cCR status of the bone metastasis for 17 months or more. Rate of cCR for 1 year or more appeared to be 15% (3/20) after comprehensive treatments including AFTV. The median overall survival time (60.0 months) and the 3- to 8-year survival rates after diagnosis of bone metastasis were greater than those of historical control cohorts in Japan (1988-2002) and in the nationwide population-based cohort study of Denmark (1999-2007). Conclusion: Bone-metastatic breast cancer may be curable after comprehensive treatments including AFTV, although larger scale clinical trial is required.

PMID- 29576885 TI - Revising Reverse-Phase Chromatographic Behavior for Efficient Differentiation of Both Positional and Geometrical Isomers of Dicaffeoylquinic Acids. AB - Dicaffeoylquinic acids (diCQAs) are plant metabolites and undergo trans-cis isomerization when exposed to UV irradiation. As such, diCQAs exist in both trans and cis-configurations and amplify the already complex plant metabolome. However, analytical differentiation of these geometrical isomers using mass spectrometry (MS) approaches has proven to be extremely challenging. Exploring the chromatographic space to develop possible conditions that would aid in differentially separating and determining the elution order of these isomers is therefore imperative. In this study, simple chromatographic parameters, such as column chemistry (phenyl versus alkyl), mobile phase composition (methanol or acetonitrile), and column temperature, were investigated to aid in the separation of diCQA geometrical isomers. The high-performance liquid chromatography photodiode array (HPLC-PDA) chromatograms revealed four isomers post UV irradiation of diCQA authentic standards. The elution profile/order was seen to vary on different reverse-phase column chemistries (phenyl versus alkyl) using different mobile phase composition. Here, the elution profile/order on the phenyl derived column matrices (with methanol as the mobile phase composition) was observed to be relatively reproducible as compared to the alkyl (C18) columns. Chromatographic resolution of diCQA geometrical isomers can be enhanced with an increase in column temperature. Lastly, the study highlights that chromatographic elution order/profile cannot be relied upon to fathom the complexity of isomeric plant metabolites. PMID- 29576886 TI - A Localized Surface Plasmon Resonance Sensing Method for Simultaneous Determination of Atenolol and Amiloride in Pharmaceutical Dosage Forms and Urine Samples. AB - This contribution describes a simple, fast, and sensitive application of localized surface plasmon resonance effect of silver nanoparticles for simultaneous determination of antihypertensive drugs' mixture atenolol and amiloride in both pharmaceutical dosage forms and in biological samples (urine). Silver nanoparticles were prepared by chemical reduction of silver nitrate using hydroxylamine HCL in an alkaline medium. Application of silver-hydroxylamine nanoparticles (SH NPs) provides many advantages including reproducibility, sensitivity, and cost effective way of analyte determination. Amiloride has four amino groups which act as attachment points on the surface of silver nanoparticles resulting in a synergistic effect on the absorption intensity of atenolol, leading to increase the sensitivity of the determination of both compounds. This method shows excellent advantages comparing with the previously reported methods, including accuracy, precision, and selectivity. The linear range of atenolol is 1 * 10-5-1 * 10-4 mol.L-1 and of amiloride is 1 * 10-6-1 * 10-5 mol.L-1. The limit of detection (LOD) values of atenolol and amiloride are 0.89 * 10-5 and 0.42 * 10-6 mol.L-1, respectively. PMID- 29576887 TI - Two-color multiphoton in vivo imaging with a femtosecond diamond Raman laser. AB - Two-color multiphoton microscopy through wavelength mixing of synchronized lasers has been shown to increase the spectral window of excitable fluorophores without the need for wavelength tuning. However, most currently available dual output laser sources rely on the costly and complicated optical parametric generation approach. In this report, we detail a relatively simple and low cost diamond Raman laser pumped by a ytterbium fiber amplifier emitting at 1055 nm, which generates a first Stokes emission centered at 1240 nm with a pulse width of 100 fs. The two excitation wavelengths of 1055 and 1240 nm, along with the effective two-color excitation wavelength of 1140 nm, provide an almost complete coverage of fluorophores excitable within the range of 1000-1300 nm. When compared with 1055 nm excitation, two-color excitation at 1140 nm offers a 90% increase in signal for many far-red emitting fluorescent proteins (for example, tdKatushka2). We demonstrate multicolor imaging of tdKa-tushka2 and Hoechst 33342 via simultaneous two-color two-photon, and two-color three-photon microscopy in engineered 3D multicellular spheroids. We further discuss potential benefits and applications for two-color three-photon excitation. In addition, we show that this laser system is capable of in vivo imaging in mouse cortex to nearly 1 mm in depth with two-color excitation.

AB - Long non-coding RNAs (lncRNAs) are comprised of RNA transcripts exceeding 200 nucleotides in length but lacking identifiable open reading frames (with rare exceptions). Herein, we highlight emerging evidence demonstrating that lncRNAs are critical regulators of liver metabolic function and diseases. We summarize current knowledges about dysregulated lncRNAs and outline the underlying molecular mechanisms by which lncRNAs control hepatic lipid ad glucose metabolism, as well as cholestatic liver disease. lncLSTR, Lnc18q22.2, SRA, HULC, MALAT1, lncLGR, MEG3, and H19, lncHR1, lnc-HC, APOA1-AS, DYNLRB2-2, and LeXis are included in the discussion. PMID- 29576889 TI - Recent development and gene therapy for glycogen storage disease type Ia. AB - Glycogen storage disease type Ia (GSD-Ia) is an autosomal recessive metabolic disorder caused by a deficiency in glucose-6-phosphatase-alpha (G6Pase-alpha or G6PC) that is expressed primarily in the liver, kidney, and intestine. G6Pase alpha catalyzes the hydrolysis of glucose-6-phosphate (G6P) to glucose and phosphate in the terminal step of gluconeogenesis and glycogenolysis, and is a key enzyme for endogenous glucose production. The active site of G6Pase-alpha is inside the endoplasmic reticulum (ER) lumen. For catalysis, the substrate G6P must be translocated from the cytoplasm into the ER lumen by a G6P transporter (G6PT). The functional coupling of G6Pase-alpha and G6PT maintains interprandial glucose homeostasis. Dietary therapies for GSD-Ia are available, but cannot prevent the long-term complication of hepatocellular adenoma that may undergo malignant transformation to hepatocellular carcinoma. Animal models of GSD-Ia are now available and are being exploited to both delineate the disease more precisely and develop new treatment approaches, including gene therapy. PMID- 29576890 TI - Long-term Results in Pediatric Developmental Cataract Surgery with Primary Intraocular Lens Implantation. AB - Objectives: The aim of this study was to evaluate the outcomes of pediatric developmental cataract surgery with primary intraocular lens (IOL) implantation. Materials and Methods: Patients between 2 and 16 years old who underwent cataract surgery with primary IOL implantation were retrospectively evaluated. Age at time of surgery, pre- and postoperative best corrected visual acuities, postoperative ocular complications, and any accompanying ocular pathologies were obtained from the patients' charts. Mean refractive changes and degree of myopic shift were analyzed according to the age groups. Operated eyes were also compared with the fellow eyes in unilateral cases. Results: A total of 101 eyes of 65 patients were included. The average age at time of surgery was 76+/-40 months and the average follow-up period was 44+/-30 months. Among the 78 eyes that could be assessed for visual acuity improvement, 66 (84.6%) of them showed >=2 lines of improvement. The difference in the mean refractive change between the 2-5 years old and 8-16 years old age groups was found to be statistically significant. However, the mean refractive change per year was not found to be significant between the same age groups. In unilateral cases, the operated eyes showed a greater myopic change than the fellow eyes, with no statistically significant difference. The most common postoperative complication was visual axis opacity. Conclusion: Good visual outcomes can be achieved following pediatric cataract surgery with primary IOL implantation. Optic axis opacities were the most common postoperative complications. Overall, refractive changes following surgery are inevitable, and more prominent in younger age groups. PMID- 29576891 TI - Visual Results Following Implantation of a Refractive Multifocal Intraocular Lens in One Eye and a Diffractive in the Contralateral Eye. AB - Objectives: To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a "mix and match" approach. Materials and Methods: Twenty patients (40 eyes) were involved in this prospective, nonrandomized study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients' dominant eyes and diffractive multifocal IOLs (Tecnis ZMA00) were implanted in their non-dominant eyes. Monocular and binocular uncorrected distance, intermediate and near visual acuity (logMAR), and contrast sensitivity levels were measured at 1, 3, and 6 months after cataract surgery. Defocus curves, reading speeds, patient satisfaction, spectacle dependence, and halo and glare symptoms were also evaluated at 6 months after the surgery. Postoperative quality of life was assessed with the Turkish version of National Eye Institute Visual Function Questionnaire-25. Results: The study group comprised 8 females and 12 males with a mean age of 69.45+/-10.76 years (range, 31-86 years). The uncorrected distance and intermediate visual acuity levels were significantly better in the ReZoom-implanted eyes at postoperative 6 months (p=0.026 and p=0.037, respectively). There was no statistically significant difference in uncorrected near visual acuity (p>0.05). There was no statistically significant difference in contrast sensitivity, reading speed, halos, or glare between the groups (p<0.05). Mild glare/halo was reported by 40% of the subjects. The mean patient satisfaction was 95% and all patients were spectacle independent. Conclusion: Mixing and matching multifocal IOLs in selected cataract patients provides excellent visual outcome, a high level of patient satisfaction, and spectacle independency. PMID- 29576892 TI - Amniotic Membrane Transplantation in Surgical Treatment of Conjunctival Melanoma: Long-term Results. AB - Objectives: To investigate the long-term efficacy and results of surgical management of conjunctival melanoma reconstructed with amniotic membrane transplantation. Materials and Methods: Conjunctival melanoma in 10 patients (5 female, 5 male) was totally excised with adjunctive cryotherapy to the surgical margins, corneal epitheliectomy with absolute alcohol in cases of corneal involvement, lamellar sclerectomy in cases with episcleral involvement, and ocular surface grafting with cryopreserved amniotic membrane. Complications and tumor control rates were evaluated. Results: The mean age of the patients was 57.4+/-15.2 (range, 37-84) years. The mean diameter of the tumors was 15.5+/-4.9 (range, 10-25) mm and histopathologically confirmed complete excision was performed in all cases. Mild limbal stem cell deficiency (2 eyes) and subclinical symblepharon (3 eyes) were observed as long-term complications. In a mean follow up of 56.7+/-40.4 (range, 30-132) months, only one local tumor recurrence was detected. Despite retreatment, exenteration was performed in this patient due to re-recurrence. One patient died due to disseminated metastasis despite the absence of local recurrence. Conclusion: In large conjunctival melanomas, reconstruction of the ocular surface is usually very challenging. The use of cryopreserved amniotic membrane for conjunctival defect repair is safe and effective with mild complications, and allows the excision of wider margins around the tumor. PMID- 29576893 TI - The Profile and Management of Glaucoma in Adult Aphakic Patients Following Complicated Cataract Surgery. AB - Objectives: To determine the profile and clinical course of glaucoma in adult aphakic patients following complicated cataract surgery. Materials and Methods: Retrospective chart review of 22 adult aphakic patients (29 eyes) with glaucoma. Results: Mean age was 57.69+/-14.18 years when aphakia occurred. Mean age at time of presentation to our glaucoma clinic was 62.57+/-12.47 years. Mean follow-up time was 42.83+/-57.04 months. Changes between the first and last follow-up visits were as follows: mean intraocular pressure decreased from 26.21+/-13.86 mmHg to 18.14+/-9.63 mmHg (p=0.003); mean number of glaucoma medications used increased from 1.41+/-1.27 to 2.07+/-1.04 (p=0.005); and mean vertical cup/disc ratio increased from 0.69+/-0.25 to 0.78+/-0.24 (p=0.024). Glaucoma was managed using medications in 26 eyes (89.7%), whereas 3 eyes underwent surgical treatment. However, surgery alone was not sufficient to control intraocular pressure and additional glaucoma medications were needed. Conclusion: Prevention of glaucomatous optic neuropathy in aphakic patients is challenging both medically and surgically. Although a significant decrease in intraocular pressure can be achieved with glaucoma medications, glaucomatous disc changes may progress. PMID- 29576894 TI - Characteristics of Anisometropic Patients with and without Strabismus. AB - Objectives: To evaluate the risk factors for strabismus in patients with anisometropia by comparing degree of anisometropia, depth of amblyopia, and binocular visual function in anisometropic patients with and without strabismus. Materials and Methods: Sixty-five anisometropic patients older than 5 years with amblyopia in one eye who were followed in the Ankara University Faculty of Medicine, Department of Ophthalmology, Pediatric Ophthalmology and Strabismus Unit between May 2009 and April 2010 were included in this study. There were 27 cases of strabismus. The depth of amblyopia, degree of anisometropia, and binocular visual function were assessed in anisometropic cases with and without strabismus. Results: The 65 patients with anisometropia were divided into two groups: 27 patients with strabismus (group 1) and 38 patients without (group 2). Depth of amblyopia was greater in patients with strabismus compared to those without (p=0.006). In patients with strabismus, there was no correlation between angle of deviation and depth of amblyopia (p=0.453). In anisometropic amblyopia patients without strabismus, there was a positive correlation between depth of anisometropia and depth of amblyopia (p=0.35, Pearson's correlation coefficient=0.343). Comparison in terms of anisometropia showed that patients with strabismus had significantly larger spherical difference between the two eyes than in patients without strabismus (p=0.000, Mann-Whitney U test). There was no significant difference in terms of cylindrical values (p=0.146, Mann Whitney U test). There was no statistically significant difference in the presence of fusion between anisometropic patients with and without strabismus. Conclusion: The risk of developing strabismus increased as degree of anisometropia increased in anisometropic cases. In addition, depth of amblyopia was greater in anisometropic patients with strabismus.

AB - Objectives: The aim was to quantify the direct medical cost of neovascular age related macular degeneration (AMD) versus gained or preserved vision. Materials and Methods: Data of patients treated for neovascular AMD between January 2009 to January 2014 were reviewed. Patients with complete follow-up for two years, treated with only intravitreal ranibizumab injections and with no intraocular surgery were included. Demographics, diagnostic investigations, the number of visits and injections, changes in visual acuity (VA) at one year and two years from baseline were noted. Total cost was calculated for the first and second years, and the cost of improving or preserving initial vision level was determined with subgroup analysis. Results: Two-hundred eyes of 175 patients (86 male and 89 female) with a mean age of 72.3+/-7.8 years were included. Mean VA was 0.67 logMAR at baseline, 0.60 logMAR at the end of the first year, and 0.67 logMAR at the end of the second year. At the end of the 2 years, VA increased in 82 eyes (41%), remained the same in 42 eyes (21%), and decreased in 76 eyes (38%). The mean number of visits in the first and second years were 6.56 (3-12) and 5.74 (3-10), respectively. An average of 4.42 (1-8) injections were performed in the first year and 2.25 (0-7) in the second. The total direct medical cost for AMD was 9,628 TL (Turkish Lira) per patient for 2 years, which consisted of 529 TL in visit costs, 115 TL in fluorescein and indocyanine angiography costs, 611 TL in injection procedure costs, and 8,371 TL in drug costs. The cost of one line of VA gain was 11,911 TL in the first year. Conclusion: This study showed that treatment increased or stabilized vision in a reasonable proportion of patients, that cost of management decreases in the second year, and that drug expenses are the leading item in reimbursement. PMID- 29576896 TI - Stem Cell Treatment in Retinal Diseases: Recent Developments. AB - Stem cells are undifferentiated cells which have the ability to self-renew and differentiate into mature cells. They are highly proliferative, implying that an unlimited number of mature cells can be generated from a given stem cell source. On this basis, stem cell replacement therapy has been evaluated in recent years as an alternative for various pathologies. Degenerative retinal diseases cause progressive visual decline which originates from continuing loss of photoreceptor cells and outer nuclear layers. Theoretically, this therapy will enable the generation of new retinal cells from stem cells to replace the damaged cells in the diseased retina. In addition, stem cells are able to perform multiple functions, such as immunoregulation, anti-apoptosis of neurons, and neurotrophin secretion. With recent progress in experimental stem cell applications, phase I/II clinical trials have been approved. These latest stem cell transplantation studies showed that this therapy is a promising approach to restore visual function in eyes with degenerative retinal diseases such as retinitis pigmentosa, Stargardts' macular dystrophy, and age-related macular degeneration. This review focuses on new developments in stem cell therapy for degenerative retinal diseases. PMID- 29576897 TI - Primary Conjunctival Tuberculosis. AB - A 12-year-old girl was referred to our clinic because of unilateral conjunctivitis not responding to treatment. In the left eye, lower bulbar and tarsal conjunctiva had a polypoidal appearance due to micronodules and there was a subconjunctival nodular mass in the inferior fornix. Systemic examination was unremarkable except for a left preauricular lymphadenopathy. Excision biopsy of the subconjunctival mass revealed a granulomatous inflammation with caseation necrosis, but acid-fast bacilli (AFB) was negative. Fine needle-aspiration biopsy of the preauricular lymph node was performed. In microbiological examination, both AFB and mycobacterial culture were positive. The isolated mycobacteria strains were identified as Mycobacterium tuberculosis complex and full remission was achieved with 6 months of anti-tuberculosis treatment. Although primary tuberculous conjunctivitis is a very rare condition, it should be considered in the differential diagnosis of treatment-resistant unilateral conjunctivitis. For definitive diagnosis, microbiological and histopathological examinations should be performed both in conjunctiva and regional lymph node. PMID- 29576898 TI - Orbital Apex Syndrome Secondary to Herpes Zoster Ophthalmicus. AB - Orbital apex syndrome is a rare complication of herpes zoster ophthalmicus. A patient being followed in our clinic for herpes zoster ophthalmicus developed orbital apex syndrome in the second week of treatment. Clinical diagnosis was supported by magnetic resonance imaging. Treatment with systemic steroid and antiviral therapy resulted in total regression of ophthalmoplegia at 2 months. However, optic neuropathy-induced vision loss was permanent. This case report examines orbital apex syndrome secondary to herpes zoster ophthalmicus, which has rarely been documented in the ophthalmic literature. PMID- 29576899 TI - Goldmann-Favre Syndrome: Case Series. AB - Goldmann-Favre syndrome, which is caused by mutation of the NR2E3 gene, is a retinal degenerative disease with a wide spectrum of phenotypic properties. Variations in clinical presentation result in difficulties in differential diagnosis. In this article, Goldmann-Favre syndrome cases with different clinical findings are presented. Clinical characteristics of our cases were reviewed and discussed in light of the literature. PMID- 29576900 TI - Three Cases of Congenital Retinal Macrovessel, One Coexisting with Cilioretinal Artery. AB - In this report, we describe three cases of retinal macrovessel. Two of the three patients presented to our clinic for annual eye exam and had no visual complaints. The third patient presented because of vision loss in the left eye. Two patients had 20/20 best corrected visual acuity in both eyes and the third patient had 20/20 in the right eye, 20/25 in the left eye. Pupillary exams were normal. Slit-lamp examinations of the anterior segment were unremarkable. Fundus examination revealed macrovessels in the left eyes of two patients and in the right eye of one patient. The patients underwent complete ophthalmological examinations including color fundus photography for all three patients and optic coherence tomography, fundus autoflorescence, and fundus fluorescein angiography for two of the patients. Cilioretinal artery coexisting with macrovessel was seen angiography in one case. Congenital retinal macrovessel is a rare vascular condition. It is often unilateral and the vessel is an aberrantly large branch of the retinal arteries or veins. They may cross the fovea and their visual impact is minimal. The coexistence of congenital retinal macrovessel and cilioretinal artery is very rare. Visual impairment may occur in congenital retinal macrovessel due to retinal cavernous hemangioma, foveal cysts, central serous retinopathy, and other retinal vascular abnormalities. PMID- 29576901 TI - Rhabdomyolysis following minimally invasive transforaminal lumbar interbody fusion: Case report. AB - Background: Rhabdomyolysis results from the release of large quantities of muscle cell contents into plasma resulting in a classic triad of symptoms - muscle pain, weakness, and brown urine. Only a handful of rhabdomyolysis cases occurring after spinal surgery have been reported. Case Description: A 36-year-old male underwent an uneventful right-sided, minimally invasive transforaminal lumbar interbody fusion (miTLIF) for intractable lower back pain and right lower extremity radiculopathy attributed to L4-S1 degenerative spondylosis (DS). Postoperatively, the patient complained of intractable lower extremity pain resistant to medical management. He was subsequently diagnosed with rhabdomyolysis, and aggressive intravenous fluid resuscitation resulted in complete recovery. Conclusions: Rhabdomyolysis should be diagnosed and treated promptly with aggressive intravenous fluid resuscitation to avoid acute kidney injury following miTLIF surgery. PMID- 29576902 TI - Maladjustment of programmable ventricular shunt valves by inadvertent exposure to a common hospital device. AB - Background: Programmable ventricular shunt valves are commonly used to treat hydrocephalus. They can be adjusted to allow for varying amounts of cerebrospinal fluid (CSF) flow using an external magnetic programming device, and are susceptible to maladjustment from inadvertent exposure to magnetic fields. Case Description: We describe the case of a 3-month-old girl treated for hydrocephalus with a programmable StrataTM II valve found at the incorrect setting on multiple occasions during her hospitalization despite frequent reprogramming and surveillance. We found that the Vocera badge, a common hands-free wireless communication system worn by our nursing staff, had a strong enough magnetic field to unintentionally change the shunt setting. The device is worn on the chest bringing it into close proximity to the shunt valve when care providers hold the baby, resulting in the maladjustment. Conclusion: Some commonly used medical devices have a magnetic field strong enough to alter programmable shunt valve settings. Here, we report that the magnetic field from the Vocera hands free wireless communication system, combined with the worn position, results in shunt maladjustment for the StrataTM II valve. Healthcare facilities using the Vocera badges need to put protocols in place and properly educate staff members to ensure the safety of patients with StrataTM II valves. PMID- 29576903 TI - Ruptured posterior cerebral artery aneurysm presenting with a contralateral cranial nerve III palsy: A case report. AB - Background: Posterior cerebral artery aneurysms can frequently present with an ipsilateral cranial nerve III palsy. Case Description: We report the first case of a posterior cerebral artery aneurysm associated with a contralateral cranial nerve III palsy. A 64-year-old male presented with acute subarachnoid hemorrhage, Hunt and Hess grade 3, and a left-sided fixed and dilated pupil. Computed tomography scan showed hemorrhage, mainly within the left basal cisterns. Digital subtraction angiography revealed a right-sided P1-P2 junction aneurysm. Conclusions: This case demonstrates that, although the neurological exam can help pinpoint the location of a lesion, false localizing signs should be recognized. PMID- 29576904 TI - Noninvasive measures of brain edema predict outcome in pediatric cerebral malaria. AB - Background: Increased brain volume (BV) and subsequent herniation are strongly associated with death in pediatric cerebral malaria (PCM), a leading killer of children in developing countries. Accurate noninvasive measures of BV are needed for optimal clinical trial design. Our objectives were to examine the performance of six different magnetic resonance imaging (MRI) BV quantification measures for predicting mortality in PCM and to review the advantages and disadvantages of each method. Methods: Receiver operator characteristics were generated from BV measures of MRIs of children admitted to an ongoing research project with PCM between 2009 and 2014. Fatal cases were matched to the next available survivor. A total of 78 MRIs of children aged 5 months to 13 years (mean 4.0 years), of which 45% were males, were included. Results: Areas under the curve (AUC) with 95% confidence interval on measures from the initial MRIs were: Radiologist-derived score = 0.69 (0.58-0.79; P = 0.0037); prepontine cistern anteroposterior (AP) dimension = 0.70 (0.56-0.78; P = 0.0133); SamKam ratio [Rt. parietal lobe height/(prepontine AP dimension + fourth ventricle AP dimension)] = 0.74 (0.63 0.83; P = 0.0002); and global cerebrospinal fluid (CSF) space ascertained by ClearCanvas = 0.67 (0.55-0.77; P = 0.0137). For patients with serial MRIs (n = 37), the day 2 global CSF space AUC was 0.87 (0.71-0.96; P < 0.001) and the recovery factor (CSF volume day 2/CSF volume day 1) was 0.91 (0.76-0.98; P < 0.0001). Poor prognosis is associated with radiologist score of >=7; prepontine cistern dimension <=3 mm; cisternal CSF volume <=7.5 ml; SamKam ratio >=6.5; and recovery factor <=0.75. Conclusion: All noninvasive measures of BV performed well in predicting death and providing a proxy measure for brain volume. Initial MRI assessment may inform future clinical trials for subject selection, risk adjustment, or stratification. Measures of temporal change may be used to stage PCM. PMID- 29576905 TI - Treatment of glenohumeral arthritis pain utilizing spinal cord stimulation. AB - Background: Dorsal column stimulation may be utilized to treat non-neuropathic pain attributed to glenohumeral arthritis. Case Description: An 84-year-old female presented with right shoulder pain for 3 years. She was diagnosed with glenohumeral arthritis and a complete loss of the joint space. She was treated with a dorsal column stimulator, requiring the electrodes to be placed from the inferior aspect of C3 to the superior aspect of T1. Six weeks postoperatively, she reported >90% coverage of her shoulder pain, demonstrated increased right arm function, and a reduction in her use of narcotics. Conclusion: Dorsal column stimulation of C3-T1 proved to be an effective alternative treatment for drug resistant glenohumeral arthritis in an 84-year-old female with a complete loss of the joint space. PMID- 29576907 TI - Spinal case of the month with short perspective: How would you treat this L3-L4 synovial cyst? AB - Background: In this new section, Case of the Month with Short Perspective from Surgical Neurology International, we want to see how various spine surgeons would approach different spinal pathologies. In this first case, an elderly male presented with 3 years of lower back pain and progressive neurogenic claudication with bilateral radiculopathy that had exacerbated over the prior 6 months. An outside physician performed a magnetic resonance (MR) study of the lumbar spine that showed a massive synovial cyst filling the spinal canal (e.g., large bilateral cysts) at the L3-L4 level with grade I spondylolisthesis. The MR and CT studies also both demonstrated moderate L2-L3, and severe L3-L4 stenosis. Methods: Despite the massive synovial cyst filling the spinal canal at the L3-L4 level, pain management (anesthesia training) spent 3 months performing three successive epidural steroid injections accompanied by attempts at percutaneous synovial cyst aspiration/rupture. Results: By the time the patient presented to neurosurgery, he had developed severe neurogenic claudication, radiculopathy, myelopathy, and a cauda equina syndrome. Dynamic X-rays revealed a mild grade I degenerative spondylolisthesis at the L3-L4 level without active motion, while both computed tomography (CT) and MR studies confirmed moderate stenosis stenosis/ossification of the yellow ligament at the L2-L3 level, severe stenosis at L3-L4 level with spondylolisthesis, and massive bilateral synovial cysts at the L3-L4 level filling the spinal canal. Conclusions: Following an L2-L4 decompressive laminectomy without fusion (note the absence of motion intraoperatively at the L3-L4 level), the patient's symptoms resolved, and he regained normal function. How would you have managed this patient? PMID- 29576906 TI - Lower complication and reoperation rates for laminectomy rather than MI TLIF/other fusions for degenerative lumbar disease/spondylolisthesis: A review. AB - Background: Utilizing the spine literature, we compared the complication and reoperation rates for laminectomy alone vs. instrumented fusions including minimally invasive (MI) transforaminal lumbar interbody fusion (TLIF) for the surgical management of multilevel degenerative lumbar disease with/without degenerative spondylolisthesis (DS). Methods: Epstein compared complication and reoperation rates over 2 years for 137 patients undergoing laminectomy alone undergoing 2-3 level (58 patients) and 4-6 level (79 patients) Procedures for lumbar stenosis with/without DS. Results showed no new postoperative neurological deficits, no infections, no surgery for adjacent segment disease (ASD), 4 patients (2.9%) who developed intraoperative cerebrospinal fluid (CSF) fistulas, no readmissions, and just 1 reopereation for a (postoperative day 7). These rates were compared to other literature for lumbar laminectomies vs. fusions (e.g. particularly MI TLIF) addressing pathology comparable to that listed above. Results: Some studies in the literature revealed an average 4.8% complication rate for laminectomy alone vs. 8.3% for decompressions/fusion; at 5 postoperative years, reoperation rates were 10.6% vs. 18.4%, respectively. Specifically, the MI TLIF literature complication rates ranged from 7.7% to 23.0% and included up to an 8.3% incidence of wound infections, 6.1% durotomies, 9.7% permanent neurological deficits, and 20.2% incidence of new sensory deficits. Reoperation rates (1.6-6%) for MI TLIF addressed instrumentation failure (2.3%), cage migration (1.26-2.4%), cage extrusions (0.8%), and misplaced screws (1.6%). The learning curve (e.g. number of cases required by a surgeon to become proficient) for MI TLIF was the first 33-44 cases. Furthermore, hospital costs for lumbar fusions were 2.6 fold greater than those for laminectomy alone, with overall neurosurgeon reimbursement quoted in one study as high as $142,075 per year. Conclusions: The spinal literature revealed lower complication and reoperation rates for lumbar laminectomy alone vs. higher rates for instrumented fusion, including MI TLIF, for degenerative lumbar disease with/without DS. PMID- 29576908 TI - Rare case of a rapidly enlarging symptomatic arachnoid cyst of the posterior fossa in an infant: A case report and review of the literature. AB - Background: Intracranial arachnoid cysts are space-occupying lesions that typically remain stable or decrease in size over time. Cysts in infants younger than 1 year of age are remarkably different from those in older children and adults in terms of cyst localization and enlargement. Arachnoid cysts of the posterior fossa (PFACs) are very rare in infants and do not typically grow or present with clinical symptoms, such that surgical treatment is generally considered to be unnecessary. Here, we describe an extremely rare case of an infant with a rapidly enlarging symptomatic PFAC that was successfully treated with surgery. Case Description: A 4-month-old boy presented with increasing head circumference and a rapidly enlarging arachnoid cyst in the left posterior fossa with ventriculomegaly, which was documented using serial imaging over the preceding 2 months. We performed a microscopic resection of the cyst membrane to remove the mass effect as soon as possible and facilitate normal development. To confirm dural closure and prevent cerebrospinal fluid leakage, we also performed short-term (7 days) percutaneous long-tunneled external ventricle drainage after the surgery. Magnetic resonance imaging over a 4-year follow-up period revealed adequate reduction of the ventricle and cyst. The patient no longer exhibited progressive macrocrania and showed normal development. Conclusion: To our knowledge, this is the second successful case of surgical treatment of an enlarging symptomatic PFAC in an infant. Our surgical strategy for the treatment of this rare case can serve as a guide for surgeons in similar future cases. PMID- 29576909 TI - Deep brain stimulation for Alzheimer's Disease: An update. AB - Background: Dementia is among the leading causes of severe and long-term disability worldwide, decreasing the quality of life of individuals and families. Moreover, it induces an enormous economic burden on societies. The most prevalent cause of dementia is Alzheimer's disease (AD). Because current treatment options for AD are limited, deep brain stimulation (DBS) has been considered. Methods: The aim of this review is to survey the current understanding regarding the effects of DBS in AD and possibly shed light on the mechanisms of DBS in AD. We searched PubMed and Cochrane for various studies in English literature describing DBS in patients with AD and relevant preclinical studies. All related studies published from December 2013 to March 2017 were included in this review. Results: Our understanding of the neural circuitry underlying learning and memory in both rodent models and human patients has grown over the past years and provided potential therapeutic targets for DBS such as the fornix and the nucleus basalis of Meynert. Clinical results indicate that DBS is most beneficial for patients who are in the early stages of AD. Potential mechanisms of action of DBS in AD comprise long-term structural plasticity, including hippocampal enlargement as well as enhanced neurotransmitter release. Conclusion: It is still premature to conclude that DBS can be used in the treatment of AD, and the field will wait for the results of ongoing and future clinical trials. PMID- 29576910 TI - Does Race Matter in Addressing Homelessness? A Review of the Literature. AB - Since the 1980s, black persons have been overrepresented in the United States homeless population. Given that morbidity and mortality is elevated among both the black population and the homeless population in comparison to the general U.S. population, this overrepresentation has important implications for health policy. However, the racial demographics of homelessness have received little attention from policymakers. This article reviews published social and behavioral science literature that addresses the relationship between race and contemporary homelessness in the United States. This literature points to substantial differences between racial subgroups of the U.S. homeless population in vulnerabilities, health risks, behaviors, and service outcomes. Such observed differences suggest that policies and programs to prevent and end homelessness must explicitly consider race as a factor in order to be of maximum effectiveness. The limited scope of these findings also suggests that more research is needed to better understand these differences and their implications. PMID- 29576912 TI - Current Concept in the Treatment of Scaphoid Nonunion. PMID- 29576911 TI - Stereoselective olefin cyclopropanation under aerobic conditions with an artificial enzyme incorporating an iron-chlorin e6 cofactor. AB - Myoglobin has recently emerged as a promising biocatalyst for catalyzing carbene mediated cyclopropanation, a synthetically valuable transformation not found in nature. Having naturally evolved for binding dioxygen, the carbene transferase activity of this metalloprotein is severely inhibited by it, imposing the need for strictly anaerobic conditions to conduct these reactions. In this report, we describe how substitution of the native heme cofactor with an iron-chlorin e6 complex enabled the development of a biocatalyst capable of promoting the cyclopropanation of vinylarenes with high catalytic efficiency (up to 6,970 TON), turnover rate (>2,000 turnovers/min), and stereoselectivity (up to 99% de and ee) in the presence of oxygen. The artificial metalloenzyme can be recombinantly expressed in bacterial cells, enabling its application also in the context of whole-cell biotransformations. This work makes available a robust and easy-to-use oxygen-tolerant biocatalyst for asymmetric cyclopropanations and demonstrates the value of porphyrin ligand substitution as a strategy for tuning and enhancing the catalytic properties of hemoproteins in the context of abiological reactions. PMID- 29576913 TI - Current Management of Scaphoid Nonunion Based on the Biomechanical Study. AB - Scaphoid nonunion causes abnormal wrist kinematics and typically leads to carpal collapse and subsequent degenerative arthritis of the wrist. However, the natural history, including carpal collapse and degenerative arthritis of scaphoid nonunion, may vary at different fracture locations. This article reviews recent biomechanical studies related to the natural history of scaphoid nonunion. In the distal-type fractures (type B2 in Herbert classification), where the fracture located distal to the scaphoid apex, the proximal scaphoid fragment and lunate, which are connected through the dorsal scapholunate interosseous ligament (DSLIL) and dorsal intercarpal ligament (DIC), extend together, and the distal fragment of the scaphoid flexes individually. Therefore, untreated type B2 fractures normally show the humpback deformity, resulting in dorsal intercalated segment instability deformity relatively earlier after the injury. In the proximal-type fractures (type B1), where the fracture is located proximal to the scaphoid apex, the connection between the distal fragment and lunate is preserved through the DSLIL and DIC so that the scaphoid-lunate complex remains stable and the carpal collapse is less severe than that in distal-type fractures. The fracture location relative to the apex of the dorsal scaphoid ridge is a reliable landmark in the determination of the natural history of scaphoid nonunion. PMID- 29576914 TI - Biomechanics of an Articulated Screw in Acute Scapholunate Ligament Disruption. AB - Background An injury to the scapholunate interosseous ligament (SLIL) leads to instability in the scapholunate joint. Temporary fixation is used to protect the ligament during reconstruction or healing of the repair. Rigid screw fixation-by blocking relative physiological motion between the scaphoid and lunate-can lead to screw loosening, pullout, and fracture. Purpose This study aims to evaluate changes in scaphoid and lunate kinematics following SLIL injury and the effectiveness of an articulating screw at restoring preinjury motion. Materials and Methods The kinematics of the scaphoid and lunate were measured in 10 cadaver wrists through three motions driven by a motion simulator. The specimens were tested intact, immediately following SLIL injury, after subsequent cycling, and after fixation with a screw. Results Significant changes in scaphoid and lunate motion occurred following SLIL injury. Postinjury cycling increased motion changes in flexion-extension and radial-ulnar deviation. The motion was not significantly different from the intact scapholunate joint after placement of the articulating screw. Conclusion In agreement with other studies, sectioning of the SLIL led to significant kinematic changes of the scaphoid and lunate in all motions tested. Compared with intact scapholunate joint, no significant difference in kinematics was found after placement of the screw indicating a correction of some of the changes produced by SLIL transection. These findings suggest that the articulating screw may be effective for protecting a SLIL repair while allowing the physiological rotation to occur between the scaphoid and lunate. Clinical Relevance A less rigid construct, such as the articulating screw, may allow earlier wrist rehabilitation with less screw pullout or failure. PMID- 29576915 TI - A New Wrist Clinical Evaluation Score. AB - Background The number of available wrist scoring systems is limited; some of them do not include forearm rotation criteria. Purpose To describe a new electronic wrist clinical score and to present a new patient's generated wrist evaluation criterion, the subjective wrist value (SWV). Materials and Methods A new electronic wrist clinical score, the Lyon wrist score (LWS) including wrist VAS pain and function, active range of motion and strength was built into an excel file. VAS flexion-extension pain and function were evaluated independently from pronation-supination pain and function. A new patient's generated wrist evaluation criterion, SWV was described. Results The LWS is available in two versions, standard and full (the latter including forearm rotation strength). Both standard and full LWS are displayed into an automatically generated diamond shaped graph providing a comprehensive visual display of the clinical status of most osteoarticular wrist disorders. The graph also includes SWV. The LWS, combined with SWV into a graph that may be directly exported to a PowerPoint presentation, provide a new practical and comprehensive tool for following/comparing wrist osteoarticular clinical status/outcomes. Both standard and full LWS charts are available in colored versions on a related website for free download. Conclusion A comprehensive updated electronic display of osteoarticular wrist clinical status including forearm rotation criteria is provided and displayed into a graph which may be exported as such into a PowerPoint presentation for clinical analysis/comparisons.

AB - Background Obtaining wrist radiographs prior to surgeon evaluation may be wasteful for patients ultimately diagnosed with de Quervain tendinopathy (DQT). Questions/Purpose Our primary question was whether radiographs directly influence treatment of patients presenting with DQT. A secondary question was whether radiographs influence the frequency of injection and surgical release between cohorts with and without radiographs evaluated within the same practice. Patients and Methods Patients diagnosed with DQT by fellowship-trained hand surgeons at an urban academic medical center were identified retrospectively. Basic demographics and radiographic findings were tabulated. Clinical records were studied to determine whether radiographic findings corroborated history or physical examination findings, and whether management was directly influenced by radiographic findings. Frequencies of treatment with injection and surgery were separately tabulated and compared between cohorts with and without radiographs. Results We included 181 patients (189 wrists), with no differences in demographics between the 58% (110 wrists) with and 42% (79 wrists) without radiographs. Fifty (45%) of imaged wrists demonstrated one or more abnormalities; however, even for the 13 (12%) with corroborating history and physical examination findings, wrist radiography did not directly influence a change in management for any patient in this series. No difference was observed in rates of injection or surgical release either upon initial presentation, or at most recent documented follow-up, between those with and without radiographs. No differences in frequency, types, or total number of additional simultaneous surgical procedures were observed for those treated surgically. Conclusion Wrist radiography does not influence management of patients presenting DQT. Level of Evidence This is a level III, diagnostic study. PMID- 29576917 TI - Results of the Universal 2 Prosthesis in Noninflammatory Osteoarthritic Wrists. AB - Background/Purpose Many treatment options are available for wrist osteoarthritis, with the objective of decreasing pain and preserving function. In later stages when midcarpal and radiocarpal osteoarthritis occur, two choices remain: total wrist arthrodesis or total wrist arthroplasty. The purpose of this study is to present the short-term functional changes following total wrist arthroplasty with the Universal 2 total wrist system (Integra Life Sciences) in patients with noninflammatory wrist osteoarthritis. Patients and Methods Patients with severe noninflammatory wrist osteoarthritis were assessed preoperatively, 6 and 12 months after surgery using a range of motion, grip strength, pain, and the disabilities of the arm, shoulder, and hand (DASH) score. The additional assessment was performed after 1 year for a range of motion using a biaxial electrogoniometer, grip strength, DASH, and the Michigan hand questionnaire. Results All range of motion directions and grip strength did not change from preoperative values. The DASH score improved from 53 preoperatively to 14 during latest follow-up. Median patients' satisfaction score decreased with approximately 20 points during the last follow-up. Conclusion The relatively good DASH score combined with the partly maintained wrist range of motion indicates that reconstruction with the Universal 2 total wrist prosthesis should be considered in patients with end-stage noninflammatory wrist osteoarthritis. Level of Evidence Level IV, therapeutic study. PMID- 29576918 TI - Nonspanning Total Wrist Arthrodesis with a Low-Profile Locking Plate. AB - Purpose This study aims to compare the outcomes and complications of our technique for nonspanning total wrist arthrodesis using a locking plate with the standard carpometacarpal spanning technique. Methods A retrospective review of charts was performed to identify patients who underwent total wrist arthrodesis by the senior author (S.W.W.). We compared the outcomes of 15 cases of nonspanning wrist fusion with a 2.4/2.7 mm locking T plate to 11 cases of spanning wrist fusion with a 2.7/3.5 mm locking compression plate. Minimum follow up was 3 months. Indications for fusion included rheumatoid arthritis, posttraumatic arthritis, Kienbock's disease, primary osteoarthritis, juvenile inflammatory arthropathy, psoriasis, brachial plexopathy, failed hemi or total wrist arthroplasty, failed four-corner fusion, and failed proximal row carpectomy. The primary outcome was fusion. Secondary outcomes included time to union, patient-rated wrist evaluation score, numerical rating scale pain score, grip strength, and complications. Results All the wrists got fused. There were no significant differences in objective and subjective outcomes between cohorts. There were three complications (27%) in the spanning group, including tendon rupture and peri-implant fracture at the third metacarpal. This was compared with three complications (20%) in the nonspanning group, consisting of hardware removal. Discussion We achieved similar fusion rates employing both spanning and nonspanning total wrist arthrodesis techniques, without necessitating carpometacarpal arthrodesis in the latter. Complications associated with our method were comparably less severe than those reported in the literature. We advocate nonspanning arthrodesis as an alternative method for total wrist fusion with a high union rate and minimal risk of complications at the carpometacarpal joint.

AB - Background Arthroscopic debridement of the triangular fibrocartilage (TFC) is well accepted in patients with ulnar impaction syndrome with central TFC lesions. Treatment remains controversial, however, when there is no such lesion from radiocarpal view. Purpose This study assessed the clinical outcome of arthroscopic central TFC resection and debridement and secondary ulnar shortening in patients with ulnar impaction with central TFC lesion compared with patients without TFC lesion. Patients and Methods Thirty-two consecutive patients with ulnar impaction syndrome were arthroscopically treated, 16 of whom had a central lesion of the TFC that was debrided. In the 16 patients with no lesion from the radiocarpal view, the TFC was centrally resected and debrided to decompress the ulnocarpal joint. Persisting symptoms necessitated ulnar shortening in four patients in each group. Two patients underwent repeat arthroscopic TFC debridement. All patients were examined at 3, 6, and 12 months, and at final follow-up (mean: 1.7 years) following arthroscopy, respectively ulnar shortening or hardware removal. Results In both groups, pain, Krimmer, and DASH scores significantly improved. Improvements of DASH scores were significantly higher in patients without lesion at 12 months and at final follow-up. For other parameters, no significant difference was found between the two groups. Conclusion In both situations, with and without central TFC lesion, resection and debridement sufficiently reduced the ulnar-sided wrist pain and improved function in three out of four patients, and therefore qualified as the first-line treatment of ulnar impaction syndrome as arthroscopy is performed, anyway. Those patients who complained of persisting or recurrent ulnar-sided wrist pain finally benefitted from ulnar shortening osteotomy as the secondary procedure. Level of Evidence Therapeutic III, case-control study. PMID- 29576920 TI - Cadaveric Testing of a Novel Scapholunate Ligament Reconstruction. AB - Background Existing scapholunate interosseous ligament (SLIL) reconstruction techniques include fixation spanning the radiocarpal joint, which do not reduce the volar aspect of the scapholunate interval and may limit wrist motion. Questions/Purpose This study tested the ability of an SLIL reconstruction technique that approximates both the volar and dorsal scapholunate intervals, without spanning the radiocarpal joint, to restore static scapholunate relationships. Materials and Methods Scapholunate interval, scapholunate angle, and radiolunate angle were measured in nine human cadaveric specimens with the SLIL intact, sectioned, and reconstructed. Fluoroscopic images were obtained in six wrist positions. The reconstruction was performed by passing tendon graft through bone tunnels from the dorsal surface toward the volar corner of the interosseous surface. After reduction of the scapholunate articulation, the graft was tensioned within the lunate bone tunnel, secured with an interference screw in the scaphoid, and sutured to the dorsal SLIL remnant. Differences among testing states were evaluated using repeated measures ANOVA. Results There was a significant increase in the scapholunate interval in all wrist positions after complete SLIL disruption. Compared with the disrupted state, there was a significant decrease in scapholunate interval in all wrist positions after reconstruction using a tendon graft and interference screw. Conclusion Our SLIL reconstruction technique reconstructs the volar and dorsal ligaments of the scapholunate joint and adequately restores static measures of scapholunate stability. This technique does not tether the radiocarpal joint and aims to optimize volar reduction. Clinical Relevance Our technique offers an alternative option for SLIL reconstruction that successfully restores static scapholunate relationships. PMID- 29576921 TI - Morphological Associations between the Distal Radioulnar Joint and the Lunate. AB - Background Variations in morphology of the carpal bones have been described. Their implication in wrist disease and specific kinematic features has been recognized, and a better knowledge of these variations is essential. Questions/Purpose To radiographically determine any association between the morphological variations of the distal radioulnar joint (DRUJ) and the lunate bone. Materials and Methods Radiographs of 100 wrists of patients presenting to the emergency department with wrist pain and referred to our outpatient clinic were retrospectively reviewed for DRUJ inclination, ulnar variance, and radiocarpal and midcarpal morphology of the lunate. Results There were 51 females and 49 males, mean age 51.2 years (range: 21-94). There was a statistically significant association between the DRUJ inclination and the morphology of the radiocarpal side of the lunate ( p < 0.001). The mean values of ulnar variance changed according to DRUJ inclination and the radiocarpal side of the lunate ( p < 0.001) but not according to the midcarpal side of the lunate. There was no significant association between the morphology of the DRUJ and the midcarpal side of the lunate or between the midcarpal and the radiocarpal morphology of the lunate. Conclusion This study demonstrated a statistically significant association at the radiocarpal level between the DRUJ inclination, ulnar variance, and the morphology of the lunate. No association was found with the morphology of the midcarpal side of the lunate. Accordingly, a classification of these carpal associations is proposed, highlighting seven main wrist configurations. Clinical Relevance These associations can guide future studies of wrist kinematics. PMID- 29576922 TI - Botox and Thumb MCP Radial Collateral Ligament Reconstruction. AB - Background We report the use of botulinum toxin to aid in the treatment of chronic radial collateral ligament insufficiency of the thumb. Case Description Treatment included autograft tendon reconstruction and cast immobilization. Six weeks postoperatively, prior to hand therapy, the patient underwent an ultrasound guided botulinum neurotoxin A injection into the adductor pollicis muscle to negate its deforming forces on the reconstruction. The patient made an excellent recovery and 1 year postoperatively was pain free and had a stable radial collateral ligament (RCL) upon examination. Literature Review The outcomes of RCL repair and reconstruction are unpredictable, in part, due to the strong opposing forces of the adductor pollicis. Clinical Relevance The use of Botox injection may enhance the outcomes of RCL repair or reconstruction by neutralizing the deforming forces of the adductor muscle. PMID- 29576923 TI - Ulnar Lengthening/Reconstruction of Interosseous Membrane in Treatment of Osteochondroma. AB - Background: We aim to measure the quality of life and clinical and functional outcomes of a patient who had undergone ligament reconstruction of the forearm interosseous membrane, using brachioradialis tendon more ulna distraction osteogenesis in treatment with multiple cartilaginous exostosis. Case Description: We present a 11-year-old boy with congenital deformity in his right, dominant forearm,Type IIb by Masada classification. Distraction of the ulna, resection of exostosis, and reconstruction of the distal part of the interosseous membrane was performed. One year later, the patient experienced good evaluation. Wrist flexion was 70 degrees, extension was 60 degrees, radial deviation was 20 degrees, and ulnar deviation was 30 degrees. Forearm pronation was 60 degrees and supination was 90 degrees. Elbow flexion was 120 degrees, extension was -5 degrees, and digit motion was full. DASH score of 5, VAS of 0, and grip strength of 92% compared to the unaffected side were obtained. Forearm radiographic aspects showed healing of the distraction, articular congruency, the distal radioulnar joint (DRUJ), and radiocapitellum joint. The distraction distance was 28 mm, the distraction period was 67 days, the consolidation period was 96 days, and the period of fixator treatment was 92 days. The distraction speed was 0.5 mm/day. Good stability and joint congruency of the DRUJ and elbow were obtained. Good radiographic, clinical, and functional results were obtained improving the life quality of that patient. Literature Review: The treatment of forearm deformities is difficult and complicated. There is no consensus to the overall management. As there is still a lack of long-term results, the indications for surgery, various surgical options, and the timing of the intervention have been a matter of controversy in the literature. Would DRUJ be stable when ulnar lengthening is combined with excision of exostosis? Is it possible to reduce the radial head with this technique? Clinical Relevance: We would like to suggest an interosseous membrane (distal oblique band) reconstruction to improve this treatment. We believe this suggestion could maintain DRUJ and elbow more stable and functional. We agree that the best time to perform the corrections is early and gradually. We prefer to correct the ulna, radius, DRUJ and elbow in many steps than in only one procedure. PMID- 29576924 TI - Arthroscopic Synovectomy Combined with Autologous Fat Grafting in Early Stages of CMC Osteoarthritis of the Thumb. AB - Background Minimal invasive treatments such as arthroscopic techniques may be adequate to restore the anatomy and functional integrity of the thumb CMC (carpometacarpal) joint. In this paper, we reported the interposition of autologous fat tissue in combination with arthroscopic synovectomy/debridement for early stage of the thumb CMC joint osteoarthritis. Patients and Methods Twelve patients with a mean age of 46 years with early radiological stages of thumb CMC joint osteoarthritis were included. Evaluation of outcome was measured prior and 3, 12, and 24 months after surgery including, Visual Analog Scale (VAS), QuickDASH, grip and pinch strength, range of motion (ROM), and patient satisfaction. Results Pain at rest (or with load) was reduced from preoperative 4,7 (8,7) to 2 (5,9) at 3 to 6 months; 1,4 (4,3) at 12 months; and 0,75 (2,7) at 2 years after the surgery. Initial preoperative QuickDASH value of 52 points reduced to 33 (17-65) at 6 months, 23 (2-70) at 12 months, and 20 (11-29) at 24 months after the surgery. Grip strength and thumb pinch with respect to the contralateral untreated thumb was reduced in the first 12 months but recovered subsequently. ROM was equal to the contralateral thumb. Three patients suffered from tendinitis and required surgical treatment. One patient indicated prolonged pain symptoms. No infections were noted and no donor-site morbidity or side effects were detected. Conclusion Arthroscopic synovectomy combined with autologous fat graft is a reliable surgical option for early thumb CMC joint osteoarthritis and that effect continues for more than 24 months.

AB - Purpose In this literature review, functional outcomes such as Disability of Arm, Shoulder and Hand (DASH) score and the visual analog scale (VAS) of pain along with clinical outcomes such as range of movement and grip strength of treated distal radius fractures (DRF) accompanied with ulnar styloid fractures (USF) will be compared with those with isolated DRF. Materials and Methods We analyzed articles from MEDLINE, Embase, and CINAHL that met our predetermined inclusion and exclusion criteria as per the Preferred Reporting Items for Systematic Reviews and Meta-analysis statements. This resulted in the identification of 464 articles with 18 potentially eligible studies of which 6 were included at the full-text screening stage. The primary outcomes were wrist pain, range of motion, functional outcome and satisfaction, such as VAS, and the DASH questionnaire along with radiological assessment and incidence of complications. Results These studies involved 796 participants with DRF and 806 wrists with DRF; 444 (55%) of DRF had an associated USF. Three studies did not report any statistically significant difference in DASH scores between the DRF patients with or without USF. Two studies reported worse DASH scores in the group with associated USF. Wrist pain was reported to be statistically significantly worse in patients with associated USF in two studies. Grip strength did not exhibit a statistically significant difference in any groups in four studies. On assessing the range of motion of the wrist and forearm, only one study reported a statistically significant difference in flexion at 2 years follow-up, with less flexion in patients with USF. Conclusion This review suggests that there is no significant correlation between a USF and the functional and clinical outcomes of DRF treatment, albeit wrist pain and less flexion were reported in some studies to be associated with USF. There is a need for more robust evidence from large randomized controlled trials to specifically look at the effects of fixation versus nonfixation of USF on DRF, or large prospective cohort studies assessing DRF with and without USF, with a minimum of 12 months follow-up.

PMID- 29576927 TI - Encapsulated Cell Technology-Based Delivery of a Complement Inhibitor Reduces Choroidal Neovascularization in a Mouse Model. AB - Purpose: Age-related macular degeneration (AMD) is a slowly progressing disease, and risk appears to be tied to an overactive complement system. We have previously demonstrated that mouse choroidal neovascularization (CNV) and smoke induced ocular pathology can be reduced with an alternative pathway (AP) inhibitor fusion protein consisting of a complement receptor-2 fragment linked to the inhibitory domain of factor H (CR2-fH) when delivered systemically. Here we developed an experimental approach with genetically engineered encapsulated ARPE 19 cells to produce CR2-fH intravitreally. Methods: ARPE-19 cells were generated to stably express CR2 or CR2-fH, microencapsulated using sodium alginate, and injected intravitreally into 2-month-old C57BL/6J mice. CNV was induced using argon laser photocoagulation 4 weeks postinjection. Presence of capsules and progression of CNV was analyzed using optical coherence tomography. Bioavailability of CR2-fH was evaluated in retina sections by immunohistochemistry, and efficacy as an AP inhibitor by C3a ELISA. Results: Secretion of CR2-fH or CR2 from encapsulated ARPE-19 cells was confirmed. An efficacious concentration of CR2-fH capsules to reduce CNV was identified. Bioavailability studies showed that CR2-fH was present in capsules and retinas of injected mice, and reduced CNV-associated ocular C3a production. Conclusions: These findings indicate that the AP inhibitor CR2-fH, when generated intravitreally, can reduce CNV in mouse. Translational Relevance: Encapsulated ARPE-19 cells secreting CR2-fH or perhaps other antiangiogenic or prosurvival factors might be useful as a potential therapeutic tool to treat age-related macular degeneration. PMID- 29576928 TI - Interindividual Variations in Foveal Anatomy and Artifacts Seen on Inner Retinal Probability Maps from Spectral Domain OCT Scans of the Macula. AB - Purpose: We tested the hypothesis that variations in foveal morphology can account for artifacts seen on optical coherence tomography (OCT) retinal ganglion cell (RGC) layer probability maps. Methods: A total of 126 healthy subjects were tested with spectral domain (sd) OCT. Thickness and probability maps of the macular RGC plus inner plexiform layer (RGC+) were obtained with customized software. Macular b-scans were analyzed to derive three foveal anatomic parameters: width, depth, and slope. The distribution of these parameters was compared between eyes with and without circumfoveal artifacts seen in the central 4 degrees of macular RGC+ probability maps. Results: Of 126 healthy subjects, 12 (9.5%) had an abnormal circumfoveal region (artifact) on RGC+ probability maps. Based upon the normal distribution of the three anatomic parameters, only three of the 12 eyes (25%) fell outside the 95% confidence interval of one or more of the three foveal morphologic parameters. Multivariable logistic regression revealed that the parameter slope was significantly associated with the presence of these artifacts (odds ratio = 0.26; P = 0.019). However, the combination of these parameters and age explained only 11% of the total variance of these artifacts. Conclusions: Fovea morphology, as measured based upon width, depth, and slope, has a minor role in explaining artifacts seen on macular scans. Variations in the distribution of RGC+ thickness that are not reflected in our measures warrant further investigation as potential sources of artifacts. Translational Relevance: A small proportion of circumfoveal artifacts seen on RGC+ probability maps can be explained by variations in foveal anatomy. PMID- 29576929 TI - Customizing Perimetric Locations Based on En Face Images of Retinal Nerve Fiber Bundles With Glaucomatous Damage. AB - Purpose: Prior studies suggested the use of customized perimetric locations in glaucoma; these studies were limited by imaging only the superficial depths of the retinal nerve fiber layer (RNFL) and by prolonged perimetric testing. We aimed to develop a rapid perimetric test guided by high-resolution images of RNFL bundles. Methods: We recruited 10 patients with glaucoma, ages 56 to 80 years, median 68 years, and 10 controls, ages 55 to 77 years, median 68 years. The patients were selected based on discrepancies between locations of glaucomatous damage for perimetric and structural measures. Montaging was used to produce optical coherence tomography en face images of the RNFL covering much of the 24-2 grid locations. In experiment 1, we presented the Goldmann size III stimulus at preselected retinal locations of glaucomatous damage, using just two contrasts. In experiment 2, we developed an elongated sinusoidal stimulus, aligned within the defect, to measure contrast sensitivities; abnormalities were defined based on lower 95% reference limits derived from the controls. Results: The percentage of predicted locations where size III was not seen at 28 dB ranged from 16% to 80%, with a median of 48%. Contrast sensitivity for the sinusoidal stimulus was below the 95% reference range for 37 of 44 stimuli aligned within the defects. Conclusions: We developed methods for rapid perimetric testing guided by en face images of the RNFL bundles in patients with glaucoma. Results indicated ganglion cell damage under all of the visible RNFL defects. Translational Relevance: Customized perimetric locations have potential to improve clinical assessment of glaucoma. PMID- 29576930 TI - Retinal Vessel Diameters Change Within 1 Hour of Intracranial Pressure Lowering. AB - Purpose: We tested the hypotheses that retinal venule diameter (Dv) is associated with baseline intracranial pressure (ICP) level and that Dv is reduced shortly after ICP lowering. Methods: Dv and arteriole diameter (Da) were extracted from scanning laser ophthalmoscopic images in 40 eyes of 20 adult human subjects (10 with and 10 without papilledema) immediately before and after measurement of ICP (range, 10-55 cm H2O) and ICP lowering by cerebrospinal fluid (CSF) drainage via lumbar puncture (LP). Generalized estimating equations (GEE) modeled the relationship between baseline ICP, Da and Dv before LP. Additional GEE modeled the relationship between initial ICP and change in Da and Dv (post-LP - pre-LP) following ICP lowering. Results: Test-retest variability of diameter measurements ranged from 0.1 to 2.9 MUm (0.1%-2.72%). Neither Da nor Dv pre-LP was associated with baseline ICP level (P = 0.140 Dv, P = 0.914 Da, GEE). Da and Dv change after ICP lowering was associated with baseline ICP, with vessel diameters increasing with lower baseline ICP and decreasing with elevated initial ICP (P = 0.030 baseline ICP vs. Dv change, P = 0.012 baseline ICP vs. Da change, GEE models). Conclusions: Retina arteriole and venule diameters change immediately following ICP lowering. The direction of change is dependent on the initial ICP; both increased in subjects with high ICP and both decreased in subjects with normal ICP. Translational Relevance: The relationship between initial ICP and direction of retinal vessel size change following ICP lowering suggests a potential effect of ICP on cerebral and ocular hemodynamics that is relevant when considering the use of retinal vessel measurements as a clinical marker of ICP change. PMID- 29576931 TI - Gaze Following is Related to the Broader Autism Phenotype in a Sex-Specific Way: Building the Case for Distinct Male and Female Autism Phenotypes. AB - The search for a female autism phenotype is difficult, given the low diagnostic rates in females. Here, we studied potential sex differences in a core feature of autism, difficulty with eye gaze processing, among typically developing individuals who vary in the broad autism phenotype, which includes autistic-like traits that are common, continuously distributed, and similarly heritable in males and females. Participants viewed complex images of an actor in a naturalistic scene looking at one of many possible objects and had to identify the target gazed-at object. Among males, those high in autistic-like traits exhibited worse eye gaze following performance than did those low in these traits. Among females, eye gaze following behavior did not vary with autistic like traits. These results suggest that deficient eye gaze following behavior is part of the broader autism phenotype for males, but may not be a part of the female autism phenotype. PMID- 29576932 TI - Anticipatory Postural Adjustments and kinematic arm features when postural stability is manipulated. AB - Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements. The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulated. Three postures were applied: Standing (Up), Sit without feet support (SitUnsup) and Sit with feet support (SitSup). We found that challenging postural stability induced an increase of the reaction time and movement duration (observed for the SitUnsup compared to SitSUp and Up) as well as modified the upper-limb velocity profile. Indeed, a greater max velocity and a shorter deceleration time were observed under the highest stability (SitSup). Thus, these Kinematics features reflect less challenging task and simple motor plan when the body is stabilized. Concerning the APAs, we observed the presence of them independently of the postural stability. Such a result strongly suggests that APAs act to facilitate the limb movement and to counteract perturbation forces. In conclusion, the degree of stability seems particularly tuned to the motor planning of the upper-limb during a pointing task whereas the postural chain (sitting vs. standing) was also determinant for APAs. PMID- 29576933 TI - Strong genetic differentiation in tropical seagrass Enhalus acoroides (Hydrocharitaceae) at the Indo-Malay Archipelago revealed by microsatellite DNA. AB - The Indo-Malay Archipelago is regarded as a barrier that separates organisms of the Indian and Pacific Oceans. Previous studies of marine biota from this region have found a variety of biogeographic barriers, seemingly dependent on taxon and methodology. Several hypotheses, such as emergence of the Sunda Shelf and recent physical oceanography, have been proposed to account for the genetic structuring of marine organisms in this region. Here, we used six microsatellite loci to infer genetic diversity, population differentiation and phylogeographic patterns of Enhalus acoroides across the Indo-Malay Archipelago. Heterozygosities were consistently high, and significant isolation-by-distance, consistent with restricted gene flow, was observed. Both a neighbour joining tree based on DA distance and Bayesian clustering revealed three major clusters of E. acoroides. Our results indicate that phylogeographic patterns of E. acoroides have possibly been influenced by glaciation and deglaciation during the Pleistocene. Recent physical oceanography such as the South Java Current and the Seasonally Reversing Current may also play a role in shaping the genetic patterns of E. acoroides. PMID- 29576934 TI - Out of Asia: mitochondrial evolutionary history of the globally introduced supralittoral isopod Ligia exotica. AB - The native ranges and invasion histories of many marine species remain elusive due to a dynamic dispersal process via marine vessels. Molecular markers can aid in identification of native ranges and elucidation of the introduction and establishment process. The supralittoral isopod Ligia exotica has a wide tropical and subtropical distribution, frequently found in harbors and ports around the globe. This isopod is hypothesized to have an Old World origin, from where it was unintentionally introduced to other regions via wooden ships and solid ballast. Its native range, however, remains uncertain. Recent molecular studies uncovered the presence of two highly divergent lineages of L. exotica in East Asia, and suggest this region is a source of nonindigenous populations. In this study, we conducted phylogenetic analyses (Maximum Likelihood and Bayesian) of a fragment of the mitochondrial 16S ribosomal (r)DNA gene using a dataset of this isopod that greatly expanded previous representation from Asia and putative nonindigenous populations around the world. For a subset of samples, sequences of 12S rDNA and NaK were also obtained and analyzed together with 16S rDNA. Our results show that L. exotica is comprised of several highly divergent genetic lineages, which probably represent different species. Most of the 16S rDNA genetic diversity (48 haplotypes) was detected in East and Southeast Asia. Only seven haplotypes were observed outside this region (in the Americas, Hawai'i, Africa and India), which were identical or closely related to haplotypes found in East and Southeast Asia. Phylogenetic patterns indicate the L. exotica clade originated and diversified in East and Southeast Asia, and only members of one of the divergent lineages have spread out of this region, recently, suggesting the potential to become invasive is phylogenetically constrained. PMID- 29576935 TI - Homology modeling and docking studies of a Delta9-fatty acid desaturase from a Cold-tolerant Pseudomonas sp. AMS8. AB - Membrane-bound fatty acid desaturases perform oxygenated desaturation reactions to insert double bonds within fatty acyl chains in regioselective and stereoselective manners. The Delta9-fatty acid desaturase strictly creates the first double bond between C9 and 10 positions of most saturated substrates. As the three-dimensional structures of the bacterial membrane fatty acid desaturases are not available, relevant information about the enzymes are derived from their amino acid sequences, site-directed mutagenesis and domain swapping in similar membrane-bound desaturases. The cold-tolerant Pseudomonas sp. AMS8 was found to produce high amount of monounsaturated fatty acids at low temperature. Subsequently, an active Delta9-fatty acid desaturase was isolated and functionally expressed in Escherichia coli. In this paper we report homology modeling and docking studies of a Delta9-fatty acid desaturase from a Cold tolerant Pseudomonas sp. AMS8 for the first time to the best of our knowledge. Three dimensional structure of the enzyme was built using MODELLER version 9.18 using a suitable template. The protein model contained the three conserved histidine residues typical for all membrane-bound desaturase catalytic activity. The structure was subjected to energy minimization and checked for correctness using Ramachandran plots and ERRAT, which showed a good quality model of 91.6 and 65.0%, respectively. The protein model was used to preform MD simulation and docking of palmitic acid using CHARMM36 force field in GROMACS Version 5 and Autodock tool Version 4.2, respectively. The docking simulation with the lowest binding energy, -6.8 kcal/mol had a number of residues in close contact with the docked palmitic acid namely, Ile26, Tyr95, Val179, Gly180, Pro64, Glu203, His34, His206, His71, Arg182, Thr85, Lys98 and His177. Interestingly, among the binding residues are His34, His71 and His206 from the first, second, and third conserved histidine motif, respectively, which constitute the active site of the enzyme. The results obtained are in compliance with the in vivo activity of the Delta9 fatty acid desaturase on the membrane phospholipids.

AB - Background: Green synthesis is an ecological technique for the production of well characterized metallic nanoparticles using plants. This study investigated the synthesis of silver nanoparticles (AgNPs) using a Caesalpinia ferrea seed extract as a reducing agent. Methods: The formation of AgNPs was identified by instrumental analysis, including ultraviolet-visible (UV-Vis) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) of the AgNPs, and surface-enhanced Raman scattering (SERS) spectra of rhodamine-6G (R6G). We studied the physicochemical characterization of AgNPs, evaluated them as an antifungal agent against Candida albicans, Candida kruzei, Candida glabrata and Candida guilliermondii, and estimated their minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values. Lastly, this study evaluated the cytotoxicity of the AgNPs in murine L929 fibroblasts cells using an MTT assay. Results: The UV-Vis spectroscopy, SERS, SEM and XRD results confirmed the rapid formation of spheroidal 30-50 nm AgNPs. The MIC and MFC values indicated the antifungal potential of AgNPs against most of the fungi studied and high cell viability in murine L929 fibroblasts. In addition, this study demonstrated that C. ferrea seed extracts may be used for the green synthesis of AgNPs at room temperature for the treatment of candidiasis. PMID- 29576937 TI - Phylogenetic surveys on the newt genus Tylototriton sensu lato (Salamandridae, Caudata) reveal cryptic diversity and novel diversification promoted by historical climatic shifts. AB - Global climatic transitions and Tibetan Plateau uplifts are hypothesized to have profoundly impacted biodiversity in southeastern Asia. To further test the hypotheses related to the impacts of these incidents, we investigated the diversification patterns of the newt genus Tylototriton sensu lato, distributed across the mountain ranges of southeastern Asia. Gene-tree and species-tree analyses of two mitochondrial genes and two nuclear genes revealed five major clades in the genus, and suggested several cryptic species. Dating estimates suggested that the genus originated in the early-to-middle Miocene. Under different species delimitating scenarios, diversification analyses with birth death likelihood tests indicated that the genus held a higher diversification rate in the late Miocene-to-Pliocene era than that in the Pleistocene. Ancestral area reconstructions indicated that the genus originated from the northern Indochina Peninsula. Accordingly, we hypothesized that the Miocene Climatic Transition triggered the diversification of the genus, and the reinforcement of East Asian monsoons associated with the stepwise uplifts of the Tibetan Plateau promoted the radiation of the genus in southeastern Asia during the Miocene-to Pliocene period. Quaternary glacial cycles likely had limited effects on speciation events in the genus, but mainly had contributions on their intraspecific differentiations. PMID- 29576938 TI - Evolutionary persistence in Gunnera and the contribution of southern plant groups to the tropical Andes biodiversity hotspot. AB - Several studies have demonstrated the contribution of northern immigrants to the flora of the tropical Andes-the world's richest and most diverse biodiversity hotspot. However, much less is known about the biogeographic history and diversification of Andean groups with southern origins, although it has been suggested that northern and southern groups have contributed roughly equally to the high Andean (i.e., paramo) flora. Here we infer the evolutionary history of the southern hemisphere plant genus Gunnera, a lineage with a rich fossil history and an important ecological role as an early colonising species characteristic of wet, montane environments. Our results show striking contrasts in species diversification, where some species may have persisted for some 90 million years, and whereas others date to less than 2 Ma since origination. The outstanding longevity of the group is likely linked to a high degree of niche conservatism across its highly disjunct range, whereby Gunnera tracks damp and boggy soils in cool habitats. Colonisation of the northern Andes is related to Quaternary climate change, with subsequent rapid diversification appearing to be driven by their ability to take advantage of environmental opportunities. This study demonstrates the composite origin of a mega-diverse biota. PMID- 29576939 TI - Detection of linear features including bone and skin areas in ultrasound images of joints. AB - Identifying the separate parts in ultrasound images such as bone and skin plays a crucial role in the synovitis detection task. This paper presents a detector of bone and skin regions in the form of a classifier which is trained on a set of annotated images. Selected regions have labels: skin or bone or none. Feature vectors used by the classifier are assigned to image pixels as a result of passing the image through the bank of linear and nonlinear filters. The filters include Gaussian blurring filter, its first and second order derivatives, Laplacian as well as positive and negative threshold operations applied to the filtered images. We compared multiple supervised learning classifiers including Naive Bayes, k-Nearest Neighbour, Decision Trees, Random Forest, AdaBoost and Support Vector Machines (SVM) with various kernels, using four classification performance scores and computation time. The Random Forest classifier was selected for the final use, as it gives the best overall evaluation results. PMID- 29576940 TI - Fuel-cell breathalyser use for field research on alcohol intoxication: an independent psychometric evaluation. AB - Background: Several field studies have used fuel-cell breathalysers (FCB) to investigate the prevalence of alcohol intoxication. However, there is a lack of evidence evaluating the psychometric properties of these breathalysers outside of the forensic disciplines. Methods: The current research describes four studies designed that assess the reliability and validity of portable platinum FCBs for research on alcohol intoxication. Utilising the Alcolizer LE5 breathalyser and, to a lesser degree, the Lifeloc FC-20 and the Lion Intoxilyzer 8000, each study sampled patrons frequenting popular night-time entertainment districts with varying levels of alcohol intoxication. Results: Study one and two found excellent test-retest reliability and inter-instrument reliability for FCBs. Study three and four provided evidence to support the convergent validity of the two FCBs (the LE5 with the FC20), and with an evidential breathalyser (i.e., the Lion Intoxilyzer 8000; EB). Discussion: A 93-97% agreement rate between breathalyser readings was found across the four studies. Portable FCB are recommended as a reliable and valid instrument for research designs requiring quick alcohol intoxication estimations in large populations. Strategies to enhance reliable and valid readings are provided for field researchers.

AB - Virus-induced gene silencing (VIGS) is an attractive tool for determining gene function in plants. The present study constitutes the first application of VIGS in S. pseudocapsicum, which has great ornamental and pharmaceutical value, using tobacco rattle virus (TRV) vectors. Two marker genes, PHYTOENE DESATURASE (PDS) and Mg-chelatase H subunit (ChlH), were used to test the VIGS system in S. pseudocapsicum. The photobleaching and yellow-leaf phenotypes of the silenced plants were shown to significantly correlate with the down-regulation of endogenous SpPDS and SpChlH, respectively (P <= 0.05). Moreover, the parameters potentially affecting the efficiency of VIGS in S. pseudocapsicum, including the Agrobacterium strain and the inoculation method (leaf syringe-infiltration, sprout vacuum-infiltration and seed vacuum-infiltration), were compared. The optimized VIGS parameters were the leaf syringe-infiltration method, the Agrobacterium strain GV3101 and the growth of agro-inoculated plants at 25 degrees . With these parameters, the silencing efficiency of SpPDS and SpChlH could reach approximately 50% in S. pseudocapsicum. Additionally, the suitability of various reference genes was screened by RT-qPCR using three candidate genes, and the results demonstrated that glyceraldehyde 3-phosphate dehydrogenase (GAPDH) can serve as a suitable reference for assessing the gene expression levels of VIGS systems in S. pseudocapsicum. The proven application of VIGS in S. pseudocapsicum and the characterization of a suitable reference gene in the present work will expedite the functional characterization of novel genes in S. pseudocapsicum.

AB - Introduction: Using spatial-temporal analyses to understand coverage and trends in elimination of mother-to-child transmission of HIV (e-MTCT) efforts may be helpful in ensuring timely services are delivered to the right place. We present spatial-temporal analysis of seven years of HIV early infant diagnosis (EID) data collected from 12 districts in western Kenya from January 2007 to November 2013, during pre-Option B+ use. Methods: We included in the analysis infants up to one year old. We performed trend analysis using extended Cochran-Mantel-Haenszel stratified test and logistic regression models to examine trends and associations of infant HIV status at first diagnosis with: early diagnosis (<8 weeks after birth), age at specimen collection, infant ever having breastfed, use of single dose nevirapine, and maternal antiretroviral therapy status. We examined these covariates and fitted spatial and spatial-temporal semiparametric Poisson regression models to explain HIV-infection rates using R-integrated nested Laplace approximation package. We calculated new infections per 100,000 live births and used Quantum GIS to map fitted MTCT estimates for each district in Nyanza region. Results: Median age was two months, interquartile range 1.5-5.8 months. Unadjusted pooled positive rate was 11.8% in the seven-years period and declined from 19.7% in 2007 to 7.0% in 2013, p < 0.01. Uptake of testing <=8 weeks after birth was under 50% in 2007 and increased to 64.1% by 2013, p < 0.01. By 2013, the overall standardized MTCT rate was 447 infections per 100,000 live births. Based on Bayesian deviance information criterion comparisons, the spatial temporal model with maternal and infant covariates was best in explaining geographical variation in MTCT. Discussion: Improved EID uptake and reduced MTCT rates are indicators of progress towards e-MTCT. Cojoined analysis of time and covariates in a spatial context provides a robust approach for explaining differences in programmatic impact over time. Conclusion: During this pre-Option B+ period, the prevention of mother to child transmission program in this region has not achieved e-MTCT target of <=50 infections per 100,000 live births. Geographical disparities in program achievements may signify gaps in spatial distribution of e-MTCT efforts and could indicate areas needing further resources and interventions.

AB - As a subfamily of the APETALA 2/ethylene response element binding protein (AP2/EREBP) transcription factor superfamily, the ethylene response factor (ERF) is widely involved in the regulation of growth and response to various abiotic stresses in plants, and has been shown to be the main transcription factor regulating transcription of the genes related to hypoxia and waterlogging stress. In this study, three ThERF genes, with significant differences in expression profile in response to flooding stress, were identified from the transcriptomics data acquired from Taxodium hybrid 'Zhongshanshan 406' (T. mucronatum Tenore * T. distichum (L.) Rich) under waterlogging stress: ThERF15, ThERF39 and ThRAP2.3 (GenBank ID: KY463467, KY463468 and KY463470, respectively).The full-length cDNA of each of the three ERFs was obtained using the RACE (rapid amplification cDNA ends) method, and all three were intron-free. Multiple protein sequence alignments indicated that ThERF15, ThERF39 and ThRAP2.3 proteins all had only one AP2-ERF domain and belonged to the ERF subfamily. A transient gene expression assay demonstrated that ThERF15, ThERF39 and ThRAP2.3 were all localized to the nucleus. Real-time quantitative PCR (qPCR) revealed that the expression of ThERF15, ThERF39 and ThRAP2.3 exhibited significant differences, compared with the control, in response to two levels of flooding treatment (half-flooding or total-submergence) of 'Zhongshanshan 406'. Quantification of ethylene concentration revealed that ethylene was more relevant to the level of expression than the period of flooding treatment. Based on the experimental results above, ThERF15, ThERF39 and ThRAP2.3 were identified as being related to the regulation of downstream flooding- responsive gene expression in 'Zhongshanshan 406'. ThRAP2.3 is most likely to be a key downstream-response ERF gene to respond to the output of the ethylene signal generated by flooding stress.

AB - Quinoa cultivation has been expanded around the world in the last decade and is considered an exceptional crop with the potential of contributing to food security worldwide. The exceptional nutritional value of quinoa seeds relies on their high protein content, their amino acid profile that includes a good balance of essential amino acids, the mineral composition and the presence of antioxidants and other important nutrients such as fiber or vitamins. Although several studies have pointed to the influence of different environmental stresses in certain nutritional components little attention has been paid to the effect of the agroecological context on the nutritional properties of the seeds what may strongly impact on the consumer food's quality. Thus, aiming to evaluate the effect of the agroecological conditions on the nutritional profile of quinoa seeds we analyzed three quinoa cultivars (Salcedo-INIA, Titicaca and Regalona) at different locations (Spain, Peru and Chile). The results revealed that several nutritional parameters such as the amino acid profile, the protein content, the mineral composition and the phytate amount in the seeds depend on the location and cultivar while other parameters such as saponin or fiber were more stable across locations. Our results support the notion that nutritional characteristics of seeds may be determined by seed's origin and further analysis are needed to define the exact mechanisms that control the changes in the seeds nutritional properties. PMID- 29576945 TI - Establishment and quality evaluation of a glioma biobank in Beijing Tiantan Hospital. AB - Background: We established a glioma biobank at Beijing Tiantan Hospital in November, 2010. Specialized residents have been trained to collect, store and manage the biobank in accordance with standard operating procedures. Methods: One hundred samples were selected to evaluate the quality of glioma samples stored in the liquid nitrogen tank during different periods (from 2011 to 2015) by morphological examination, RNA integrity determination, DNA integrity determination and housekeeping gene expression determination. Results: The majority of samples (95%) had high RNA quality for further analysis with RIN >=6. Quality of DNA of all samples were stable without significant degradation. Conclusion: Storage conditions of our biobank are suitable for long-term (at least five years) sample preservation with high molecular quality. PMID- 29576946 TI - Difficulties when using video playback to investigate social cognition in California scrub-jays (Aphelocoma californica). AB - Previous research has suggested that videos can be used to experimentally manipulate social stimuli. In the present study, we used the California scrub jays' cache protection strategies to assess whether video playback can be used to simulate conspecifics in a social context. In both the lab and the field, scrub jays are known to exhibit a range of behaviours to protect their caches from potential pilferage by a conspecific, for example by hiding food in locations out of the observer's view or by re-caching previously made caches once the observer has left. Here, we presented scrub-jays with videos of a conspecific observer as well as two non-social conditions during a caching period and assessed whether they would cache out of the observer's "view" (Experiment 1) or would re-cache their caches once the observer was no longer present (Experiment 2). In contrast to previous studies using live observers, the scrub-jays' caching and re-caching behaviour was not influenced by whether the observer was present or absent. These findings suggest that there might be limitations in using video playback of social agents to mimic real-life situations when investigating corvid decision making. PMID- 29576947 TI - Characterization of shifts of koala (Phascolarctos cinereus) intestinal microbial communities associated with antibiotic treatment. AB - Koalas (Phascolarctos cinereus) are arboreal marsupials native to Australia that eat a specialized diet of almost exclusively eucalyptus leaves. Microbes in koala intestines are known to break down otherwise toxic compounds, such as tannins, in eucalyptus leaves. Infections by Chlamydia, obligate intracellular bacterial pathogens, are highly prevalent in koala populations. If animals with Chlamydia infections are received by wildlife hospitals, a range of antibiotics can be used to treat them. However, previous studies suggested that koalas can suffer adverse side effects during antibiotic treatment. This study aimed to use 16S rRNA gene sequences derived from koala feces to characterize the intestinal microbiome of koalas throughout antibiotic treatment and identify specific taxa associated with koala health after treatment. Although differences in the alpha diversity were observed in the intestinal flora between treated and untreated koalas and between koalas treated with different antibiotics, these differences were not statistically significant. The alpha diversity of microbial communities from koalas that lived through antibiotic treatment versus those who did not was significantly greater, however. Beta diversity analysis largely confirmed the latter observation, revealing that the overall communities were different between koalas on antibiotics that died versus those that survived or never received antibiotics. Using both machine learning and OTU (operational taxonomic unit) co occurrence network analyses, we found that OTUs that are very closely related to Lonepinella koalarum, a known tannin degrader found by culture-based methods to be present in koala intestines, was correlated with a koala's health status. This is the first study to characterize the time course of effects of antibiotics on koala intestinal microbiomes. Our results suggest it may be useful to pursue alternative treatments for Chlamydia infections without the use of antibiotics or the development of Chlamydia-specific antimicrobial compounds that do not broadly affect microbial communities. PMID- 29576948 TI - Characterization of the salivary microbiome in people with obesity. AB - Background: The interactions between the gut microbiome and obesity have been extensively studied. Although the oral cavity is the gateway to the gut, and is extensively colonized with microbes, little is known about the oral microbiome in people with obesity. In the present study, we investigated the salivary microbiome in obese and normal weight healthy participants using metagenomic analysis. The subjects were categorized into two groups, obesity and normal weight, based on their BMIs. Methods: We characterized the salivary microbiome of 33 adults with obesity and 29 normal weight controls using high-throughput sequencing of the V3-V4 region of the 16S rRNA gene (Illumina MiSeq). None of the selected participants had systemic, oral mucosal, or periodontal diseases. Results: The salivary microbiome of the obesity group was distinct from that of the normal weight group. The salivary microbiome of periodontally healthy people with obesity had both significantly lower bacterial diversity and richness compared with the controls. The genus Prevotella, Granulicatella, Peptostreptococcus, Solobacterium, Catonella, and Mogibacterium were significantly more abundant in the obesity group; meanwhile the genus Haemophilus, Corynebacterium, Capnocytophaga, and Staphylococcus were less abundant in the obesity group. We also performed a functional analysis of the inferred metagenomes, and showed that the salivary community associated with obesity had a stronger signature of immune disease and a decreased functional signature related to environmental adaptation and Xenobiotics biodegradation compared with the normal weight controls. Discussion: Our study demonstrates that the microbial diversity and structure of the salivary microbiome in people with obesity are significantly different from those of normal weight controls. These results suggested that changes in the structure and function of salivary microbiome in people with obesity might reflect their susceptibility to oral diseases. PMID- 29576950 TI - Assessing the disturbance potential of small unoccupied aircraft systems (UAS) on gray seals (Halichoerus grypus) at breeding colonies in Nova Scotia, Canada. AB - The use of small unoccupied aircraft systems (UAS) for ecological studies and wildlife population assessments is increasing. These methods can provide significant benefits in terms of costs and reductions in human risk, but little is known if UAS-based approaches cause disturbance of animals during operations. To address this knowledge gap, we conducted a series of UAS flights at gray seal breeding colonies on Hay and Saddle Islands in Nova Scotia, Canada. Using a small fixed-wing UAS, we assessed both immediate and short-term effects of surveys using sequential image analysis and between-flight seal counts in ten, 50 m2 random quadrats at each colony. Counts of adult gray seals and young-of-the-year animals between first and second flights revealed no changes in abundance in quadrats (matched pair t-test p > 0.69) and slopes approaching 1 for linear regression comparisons (r2 > 0.80). Sequential image analysis revealed no changes in orientation or posture of imaged animals. We also assessed the acoustic properties of the small UAS in relation to low ambient noise conditions using sound equivalent level (Leq) measurements with a calibrated U-MIK 1 and a 1/3 octave band soundscape approach. The results of Leq measurements indicate that small fixed-wing UAS are quiet, with most energy above 160 Hz, and that levels across 1/3 octave bands do not greatly exceed ambient acoustic measurements in a quiet field during operations at standard survey altitudes. As such, this platform is unlikely to acoustically disturb gray seals at breeding colonies during population surveys. The results of the present study indicate that the effects of small fixed-wing UAS on gray seals at breeding colonies are negligible, and that fixed-wing UAS-based approaches should be considered amongst best practices for assessing gray seal colonies. PMID- 29576949 TI - An overview on the interplay between nutraceuticals and gut microbiota. AB - Background: Nowadays, growing attention was being given to the alternative ways to prevent or treat diseases. Nutraceuticals are used increasingly for this purpose. Many of these are being used as alternative therapy. Classic therapy with synthetic drugs, although very effective, has many side effects. The term "nutraceuticals" refers to the link between the nutritional and pharmaceutical domains. Also, lately, many studies have been done to investigate the role of microbiota in maintaining health. There is the hypothesis that some of the health benefits of nutraceuticals are due to their ability to change the microbiota. The aim of this review was to emphasize the link between the most commonly used nutraceuticals, the microbiota and the health benefits. Methods: We selected the articles in PubMed, published up to July 2017, that provided information about most used nutraceuticals, microbiota and health benefits. In this review, we incorporate evidence from various types of studies, including observational, in vitro and in vivo, clinical studies or animal experiments. Results: The results demonstrate that many nutraceuticals change the composition of microbiota and can interfere with health status of the patients. Discussion: There is evidence which sustains the importance of nutraceuticals in people's health through microbiota but further studies are needed to complete the assessment of nutraceuticals in health benefit as a consequence of microbiota's changing. PMID- 29576951 TI - Change in skeletal muscle stiffness after running competition is dependent on both running distance and recovery time: a pilot study. AB - Long-distance running competitions impose a large amount of mechanical loading and strain leading to muscle edema and delayed onset muscle soreness (DOMS). Damage to various muscle fibers, metabolic impairments and fatigue have been linked to explain how DOMS impairs muscle function. Disruptions of muscle fiber during DOMS exacerbated by exercise have been shown to change muscle mechanical properties. The objective of this study is to quantify changes in mechanical properties of different muscles in the thigh and lower leg as function of running distance and time after competition. A custom implementation of Focused Comb-Push Ultrasound Shear Elastography (F-CUSE) method was used to evaluate shear modulus in runners before and after a race. Twenty-two healthy individuals (age: 23 +/- 5 years) were recruited using convenience sampling and split into three race categories: short distance (nine subjects, 3-5 miles), middle distance (10 subjects, 10-13 miles), and long distance (three subjects, 26+ miles). Shear Wave Elastography (SWE) measurements were taken on both legs of each subject on the rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), soleus, lateral gastrocnemius (LG), medial gastrocnemius (MG), biceps femoris (BF) and semitendinosus (ST) muscles. For statistical analyses, a linear mixed model was used, with recovery time and running distance as fixed variables, while shear modulus was used as the dependent variable. Recovery time had a significant effect on the soleus (p = 0.05), while running distance had considerable effect on the biceps femoris (p = 0.02), vastus lateralis (p < 0.01) and semitendinosus muscles (p = 0.02). Sixty-seven percent of muscles exhibited a decreasing stiffness trend from before competition to immediately after competition. The preliminary results suggest that SWE could potentially be used to quantify changes of muscle mechanical properties as a way for measuring recovery procedures for runners. PMID- 29576953 TI - pcr: an R package for quality assessment, analysis and testing of qPCR data. AB - Background: Real-time quantitative PCR (qPCR) is a broadly used technique in the biomedical research. Currently, few different analysis models are used to determine the quality of data and to quantify the mRNA level across the experimental conditions. Methods: We developed an R package to implement methods for quality assessment, analysis and testing qPCR data for statistical significance. Double Delta CT and standard curve models were implemented to quantify the relative expression of target genes from CT in standard qPCR control group experiments. In addition, calculation of amplification efficiency and curves from serial dilution qPCR experiments are used to assess the quality of the data. Finally, two-group testing and linear models were used to test for significance of the difference in expression control groups and conditions of interest. Results: Using two datasets from qPCR experiments, we applied different quality assessment, analysis and statistical testing in the pcr package and compared the results to the original published articles. The final relative expression values from the different models, as well as the intermediary outputs, were checked against the expected results in the original papers and were found to be accurate and reliable. Conclusion: The pcr package provides an intuitive and unified interface for its main functions to allow biologist to perform all necessary steps of qPCR analysis and produce graphs in a uniform way. PMID- 29576952 TI - Squeezing water from a stone: high-throughput sequencing from a 145-year old holotype resolves (barely) a cryptic species problem in flying lizards. AB - We used Massively Parallel High-Throughput Sequencing to obtain genetic data from a 145-year old holotype specimen of the flying lizard, Draco cristatellus. Obtaining genetic data from this holotype was necessary to resolve an otherwise intractable taxonomic problem involving the status of this species relative to closely related sympatric Draco species that cannot otherwise be distinguished from one another on the basis of museum specimens. Initial analyses suggested that the DNA present in the holotype sample was so degraded as to be unusable for sequencing. However, we used a specialized extraction procedure developed for highly degraded ancient DNA samples and MiSeq shotgun sequencing to obtain just enough low-coverage mitochondrial DNA (721 base pairs) to conclusively resolve the species status of the holotype as well as a second known specimen of this species. The holotype was prepared before the advent of formalin-fixation and therefore was most likely originally fixed with ethanol and never exposed to formalin. Whereas conventional wisdom suggests that formalin-fixed samples should be the most challenging for DNA sequencing, we propose that evaporation during long-term alcohol storage and consequent water-exposure may subject older ethanol fixed museum specimens to hydrolytic damage. If so, this may pose an even greater challenge for sequencing efforts involving historical samples. PMID- 29576954 TI - A comparative modeling study on non-climatic and climatic risk assessment on Asian Tiger Mosquito (Aedes albopictus). AB - Aedes albopictus, the Asian Tiger Mosquito, vector of Chikungunya, Dengue Fever and Zika viruses, has proven its hardy adaptability in expansion from its natural Asian, forest edge, tree hole habitat on the back of international trade transportation, re-establishing in temperate urban surrounds, in a range of water receptacles and semi-enclosures of organic matter. Conventional aerial spray mosquito vector controls focus on wetland and stagnant water expanses, proven to miss the protected hollows and crevices favoured by Ae. albopictus. New control or eradication strategies are thus essential, particular in light of potential expansions in the southeastern and eastern USA. Successful regional vector control strategies require risk level analysis. Should strategies prioritize regions with non-climatic or climatic suitability parameters for Ae. albopictus? Our study used current Ae. albopictus distribution data to develop two independent models: (i) regions with suitable non-climatic factors, and (ii) regions with suitable climate for Ae. albopictus in southeastern USA. Non climatic model processing used Evidential Belief Function (EBF), together with six geographical conditioning factors (raster data layers), to establish the probability index. Validation of the analysis results was estimated with area under the curve (AUC) using Ae. albopictus presence data. Climatic modeling was based on two General Circulation Models (GCMs), Miroc3.2 and CSIRO-MK30 running the RCP 8.5 scenario in MaxEnt software. EBF non-climatic model results achieved a 0.70 prediction rate and 0.73 success rate, confirming suitability of the study site regions for Ae. albopictus establishment. The climatic model results showed the best-fit model comprised Coldest Quarter Mean Temp, Precipitation of Wettest Quarter and Driest Quarter Precipitation factors with mean AUC value of 0.86. Both GCMs showed that the whole study site is highly suitable and will remain suitable climatically, according to the prediction for 2055, for Ae. albopictus expansion. PMID- 29576955 TI - Measuring short distance dispersal of Alliaria petiolata and determining potential long distance dispersal mechanisms. AB - Introduction: Alliaria petiolata, an herbaceous plant, has invaded woodlands in North America. Its ecology has been thoroughly studied, but an overlooked aspect of its biology is seed dispersal distances and mechanisms. We measured seed dispersal distances in the field and tested if epizoochory is a potential mechanism for long-distance seed dispersal. Methods: Dispersal distances were measured by placing seed traps in a sector design around three seed point sources, which consisted of 15 second-year plants transplanted within a 0.25 m radius circle. Traps were placed at intervals ranging from 0.25-3.25 m from the point source. Traps remained in the field until a majority of seeds were dispersed. Eight probability density functions were fitted to seed trap counts via maximum likelihood. Epizoochory was tested as a potential seed dispersal mechanism for A. petiolata through a combination of field and laboratory experiments. To test if small mammals transport A. petiolata seeds in their fur, experimental blocks were placed around dense A. petiolata patches. Each block contained a mammal inclusion treatment (MIT) and control. The MIT consisted of a wood-frame (31 * 61* 31 cm) covered in wire mesh, except for the two 31 * 31 cm ends, placed over a germination tray filled with potting soil. A pan filled with bait was placed in the center of the tray. The control frame (11 * 31 * 61 cm) was placed over a germination tray and completely covered in wire mesh to exclude animal activity. Treatments were in the field for peak seed dispersal. In March, trays were moved to a greenhouse and A. petiolata seedlings were counted and then compared between treatments. To determine if A. petiolata seeds attach to raccoon (Procyon lotor) and white-tailed deer (Odocoileus virginianus) fur, wet and dry seeds were dropped onto wet and dry fur. Furs were rotated 180 degrees and the seeds that remained attached were counted. To measure seed retention, seeds were dropped on furs and rotated as before, then the furs were agitated for one hour. The seeds retained in the fur were counted. Results: For the seed dispersal experiment, the 2Dt function provided the best fit and was the most biologically meaningful. It predicted that seed density rapidly declined with distance from the point source. Mean dispersal distance was 0.52 m and 95% of seeds dispersed within 1.14 m. The epizoochory field experiment showed increased mammal activity and A. petiolata seedlings in germination trays of the MIT compared to control. Laboratory studies showed 3-26% of seeds were attached and retained by raccoon and deer fur. Retention significantly increased if either seed or fur were wet (57-98%). Discussion: Without animal seed vectors, most seeds fall within a short distance of the seed source; however, long distance dispersal may be accomplished by epizoochory. Our data are consistent with A. petiolata's widespread distribution and development of dense clusters of the species in invaded areas. PMID- 29576956 TI - Phylogeographic structure in three North American tent caterpillar species (Lepidoptera: Lasiocampidae): Malacosoma americana, M. californica, and M. disstria. AB - While phylogeographic structure has been examined in many North American vertebrate species, insects have received much less attention despite their central ecological roles. The moth genus Malacosoma (Hubner, 1820), is an important group of forestry pests responsible for large-scale defoliation across much of the Nearctic and Palearctic. The present study uses sequence variation in the mitochondrial cytochrome c oxidase 1 (COI) gene to examine the population genetic structure of the three widespread Malacosoma species (M. americana, M. californica, and M. disstria). Populations of all three species showed highest diversity in the south, suggesting that modern populations derived from southern refugia with loss of variation as these lineages dispersed northwards. However, despite similar life histories and dispersal abilities, the extent of regional variation varied among the taxa. M. americana, a species restricted to eastern North America, showed much less genetic structure than the western M. californica or the widespread M. disstria. The regional differentiation in the latter reflects the likely derivation of modern lineages from several refugia, as well as taxonomic uncertainty in M. californica. In these respects, the three species of Malacosoma share phylogeographic patterns similar to those detected in vertebrates which are characterised by greater phylogeographic breaks in the western half of the continent and limited structure in the east. PMID- 29576957 TI - The anatomy of the foveola reinvestigated. AB - Objective: In the foveola of the eye, photoreceptors and Muller cells with a unique morphology have been described, but little is known about their 3D structure and orientation. Considering that there is an angle-dependent change in the foveolar photoreceptor response for the same light beam, known as the Stiles Crawford Effect of the first kind (SCE I), which is still not fully understood, a detailed analysis of the anatomy of the foveolar cells might help to clarify this phenomenon. Methods: Serial semithin and ultrathin sections, and focused ion beam (FIB) tomography were prepared from 32 foveolae from monkeys (Macaca fascicularis) and humans. Foveolae were also analyzed under the electron microscope. Serial sections and FIB analysis were then used to construct 3D models of central Muller and photoreceptor cells. In addition, we measured the transmission of collimated light under the light microscope at different angles after it had passed through human foveae from flat mounted isolated retinae. Results: In monkeys, outer segments of central foveolar cones are twice as long as those from parafoveal cones and do not run completely parallel to the incident light. Unique Muller cells are present in the central foveolae (area of 200 um in diameter) of humans and monkeys. Light entering the fovea center, which is composed only of cones and Muller cells, at an angle of 0 degrees causes a very bright spot after passing through this area. However, when the angle of the light beam is changed to 10 degrees , less light is measured after transpasssing through the retina, the foveolar center becomes darker and the SCE-like phenomenon is directly visible. Measurements of the intensities of light transmission through the central foveola for the incident angles 0 and 10 degrees resemble the relative luminance efficiency for narrow light bundles as a function of the location where the beam enters the pupil as reported by Stiles and Crawford. The effect persisted after carefully brushing away the outer segments. Conclusion: We show that unique cones and Muller cells with light fibre like properties are present in the center of the fovea. These unique Muller cells cause an angle dependent, SCE-like drop in the intensity of light guided through the foveola. Outer segments from the foveolar cones of monkeys are not straight. PMID- 29576958 TI - Ecosystem functional response across precipitation extremes in a sagebrush steppe. AB - Background: Precipitation is predicted to become more variable in the western United States, meaning years of above and below average precipitation will become more common. Periods of extreme precipitation are major drivers of interannual variability in ecosystem functioning in water limited communities, but how ecosystems respond to these extremes over the long-term may shift with precipitation means and variances. Long-term changes in ecosystem functional response could reflect compensatory changes in species composition or species reaching physiological thresholds at extreme precipitation levels. Methods: We conducted a five year precipitation manipulation experiment in a sagebrush steppe ecosystem in Idaho, United States. We used drought and irrigation treatments (approximately 50% decrease/increase) to investigate whether ecosystem functional response remains consistent under sustained high or low precipitation. We recorded data on aboveground net primary productivity (ANPP), species abundance, and soil moisture. We fit a generalized linear mixed effects model to determine if the relationship between ANPP and soil moisture differed among treatments. We used nonmetric multidimensional scaling to quantify community composition over the five years. Results: Ecosystem functional response, defined as the relationship between soil moisture and ANPP, was similar among irrigation and control treatments, but the drought treatment had a greater slope than the control treatment. However, all estimates for the effect of soil moisture on ANPP overlapped zero, indicating the relationship is weak and uncertain regardless of treatment. There was also large spatial variation in ANPP within-years, which contributes to the uncertainty of the soil moisture effect. Plant community composition was remarkably stable over the course of the experiment and did not differ among treatments. Discussion: Despite some evidence that ecosystem functional response became more sensitive under sustained drought conditions, the response of ANPP to soil moisture was consistently weak and community composition was stable. The similarity of ecosystem functional responses across treatments was not related to compensatory shifts at the plant community level, but instead may reflect the insensitivity of the dominant species to soil moisture. These species may be successful precisely because they have evolved life history strategies that buffer them against precipitation variability. PMID- 29576959 TI - The use of nutritional supplements to induce ketosis and reduce symptoms associated with keto-induction: a narrative review. AB - Background: Adaptation to a ketogenic diet (keto-induction) can cause unpleasant symptoms, and this can reduce tolerability of the diet. Several methods have been suggested as useful for encouraging entry into nutritional ketosis (NK) and reducing symptoms of keto-induction. This paper reviews the scientific literature on the effects of these methods on time-to-NK and on symptoms during the keto induction phase. Methods: PubMed, Science Direct, CINAHL, MEDLINE, Alt Health Watch, Food Science Source and EBSCO Psychology and Behavioural Sciences Collection electronic databases were searched online. Various purported ketogenic supplements were searched along with the terms "ketogenic diet", "ketogenic", "ketosis" and ketonaemia (/ ketonemia). Additionally, author names and reference lists were used for further search of the selected papers for related references. Results: Evidence, from one mouse study, suggests that leucine doesn't significantly increase beta-hydroxybutyrate (BOHB) but the addition of leucine to a ketogenic diet in humans, while increasing the protein-to-fat ratio of the diet, doesn't reduce ketosis. Animal studies indicate that the short chain fatty acids acetic acid and butyric acid, increase ketone body concentrations. However, only one study has been performed in humans. This demonstrated that butyric acid is more ketogenic than either leucine or an 8-chain monoglyceride. Medium-chain triglycerides (MCTs) increase BOHB in a linear, dose-dependent manner, and promote both ketonaemia and ketogenesis. Exogenous ketones promote ketonaemia but may inhibit ketogenesis. Conclusions: There is a clear ketogenic effect of supplemental MCTs; however, it is unclear whether they independently improve time to NK and reduce symptoms of keto-induction. There is limited research on the potential for other supplements to improve time to NK and reduce symptoms of keto induction. Few studies have specifically evaluated symptoms and adverse effects of a ketogenic diet during the induction phase. Those that have typically were not designed to evaluate these variables as primary outcomes, and thus, more research is required to elucidate the role that supplementation might play in encouraging ketogenesis, improve time to NK, and reduce symptoms associated with keto-induction. PMID- 29576960 TI - Effect of fatigue and gender on kinematics and ground reaction forces variables in recreational runners. AB - The presence of fatigue has been shown to modify running biomechanics. Overall in terms of gender, women are at lower risk than men for sustaining running-related injuries, although it depends on the factors taken into account. One possible reason for these differences in the injury rate and location might be the dissimilar running patterns between men and women. The purpose of this study was to determine the effect of fatigue and gender on the kinematic and ground reaction forces (GRF) parameters in recreational runners. Fifty-seven participants (28 males and 29 females) had kinematic and GRF variables measured while running at speed of 3.3 m s-1 before and after a fatigue test protocol. The fatigue protocol included (1) a running Course-Navette test, (2) running up and down a flight of stairs for 5 min, and (3) performance of alternating jumps on a step (five sets of 1 minute each with 30 resting seconds between the sets). Fatigue decreased dorsiflexion (14.24 +/- 4.98 degrees in pre-fatigue and 12.65 +/- 6.21 degrees in fatigue condition, p < 0.05) at foot strike phase in females, and plantar flexion (-19.23 +/- 4.12 degrees in pre-fatigue and -18.26 +/- 5.31 degrees in fatigue condition, p < 0.05) at toe-off phase in males. These changes led to a decreased loading rate (88.14 +/- 25.82 BW/s in pre fatigue and 83.97 +/- 18.83 BW/s in fatigue condition, p < 0.05) and the impact peak in females (1.95 +/- 0.31 BW in pre-fatigue and 1.90 +/- 0.31 BW in fatigue condition, p < 0.05), and higher peak propulsive forces in males (-0.26 +/- 0.04 BW in pre-fatigue and -0.27 +/- 0.05 BW in fatigue condition, p < 0.05) in the fatigue condition. It seems that better responses to impact under a fatigue condition are observed among women. Further studies should confirm whether these changes represent a strategy to optimize shock attenuation, prevent running injuries and improve running economy. PMID- 29576961 TI - Clinical impact of albumin in advanced head and neck cancer patients with free flap reconstruction-a retrospective study. AB - Background: Poor nutritional status among patients with advanced stage head and neck squamous cell carcinoma (HNSCC) is common. Albumin is a common indicator of nutritional status and has been shown to be a predictor of oncological outcomes and perioperative morbidity. This study aims to determine the prognostic value of the serum albumin level among patients with advanced HNSCC undergoing surgery with simultaneous free flap reconstruction. Methods: A total of 233 patients with advanced head and neck cancer undergoing tumor resection and immediate microvascular free flap reconstruction in a tertiary referral center were enrolled retrospectively between January 2009 and December 2011. Statistical analyses including Pearson's chi-squared test were used to determine whether there was a significant difference between each selected clinical factors and postoperative major wound infection. Multiple regression analysis was performed to reveal the relationship between postoperative major wound infection and clinical factors. Kaplan-Meier curves and multivariate Cox regression were applied to analyse survival outcome for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). Results: Postoperative serum albumin level (p < 0.001) and tumor location were both significantly associated with postoperative major wound infection (p = 0.018) in univariate analysis. Multiple regression analysis showed a higher risk of postoperative major wound infection among patients with postoperative hypoalbuminemia than in their counterparts (odds ratio [OR] 9.811, 95% CI [2.288-42.065], p = 0.002). Patients with a tumor located over the hypopharynx experienced increased risk of postoperative major wound infection (OR 2.591, 95% CI [1.095-6.129], p = 0.030). With respect to oncological outcomes, preoperative serum albumin level is a significant independent prognostic factor for overall survival (OS), disease specific survival (DSS) and disease-free survival (DFS). Conclusions: Postoperative hypoalbuminemia is a useful indicator for the development of postoperative complications. In addition, preoperative hypoalbuminemia is a negative prognostic factor for patients who have undergone tumor excision and free flap reconstruction for the advanced stage of HNSCC.

AB - We review the taxonomy and ecology of Chloropidae (Diptera) associated with pitcher plants (Sarraceniaceae) in North America. Tricimba wheeleri Mlynarek sp.n. is described from the pitchers of Sarracenia alata Alph.Wood and S. leucophylla Raf. in the southeastern United States (Alabama, Mississippi). Aphanotrigonum darlingtoniae (Jones) associated with Darlingtonia californica Torr. in northern California is redescribed, including the first description of male genitalic characters. A lectotype is designated for A. darlingtoniae. Published records of other species of Tricimba Lioy in pitcher plants in North America are considered accidental or facultative occurrences; published records of Aphanotrigonum Duda as pitcher plant associates in eastern North America are probably errors in identification. PMID- 29576963 TI - Electroencephalographic modulations during an open- or closed-eyes motor task. AB - There is fundamental knowledge that during the resting state cerebral activity recorded by electroencephalography (EEG) is strongly modulated by the eyes-closed condition compared to the eyes-open condition, especially in the occipital lobe. However, little research has demonstrated the influence of the eyes-closed condition on the motor cortex, particularly during a self-paced movement. This prompted the question: How does the motor cortex activity change between the eyes closed and eyes-open conditions? To answer this question, we recorded EEG signals from 15 voluntary healthy subjects who performed a simple motor task (i.e., a voluntary isometric flexion of the right-hand index) under two conditions: eyes closed and eyes-open. Our results confirmed strong modulation in the mu rhythm (7 13 Hz) with a large event-related desynchronisation. However, no significant differences have been observed in the beta band (15-30 Hz). Furthermore, evidence suggests that the eyes-closed condition influences the behaviour of subjects. This study gives us greater insight into the motor cortex and could also be useful in the brain-computer interface (BCI) domain. PMID- 29576964 TI - Saccadic inhibition in a guided saccade task. AB - The eye movement system reacts very systematically to visual transients that are presented during the planning phase of a saccade. About 50 to 70 ms after the onset of a transient, the number of saccades that are started decreases, a phenomenon that has been termed saccadic inhibition. Saccades started just before this time window are hypometric compared to regular saccades, presumably because the presentation of the transient stops them in mid-flight. Recent research investigating the properties of repeated saccades to fixed locations found that these early saccades were additionally faster than expected from the main sequence relation, suggesting that a saccadic dead time during which saccades can no longer be modified does not exist. The present study investigated the properties of saccades to random locations in a guided saccade task. As expected, early saccades starting just before the saccadic inhibition dip in frequency were hypometric. Their velocity profiles implied that these saccades were actively stopped after reaching peak velocity. However, the peak velocities of these saccades did not generally deviate from the main sequence relation. The question whether an active stop of early saccades is incompatible with the idea of a saccadic dead time is open to debate. PMID- 29576965 TI - A genome-wide investigation of microsatellite mismatches and the association with body mass among bird species. AB - Mutation rate is usually found to covary with many life history traits of animals such as body mass, which has been readily explained by the higher number of mutation opportunities per unit time. Although the precise reason for the pattern is not yet clear, to determine the universality of this pattern, we tested whether life history traits impact another form of genetic mutation, the motif mismatches in microsatellites. Employing published genome sequences from 65 avian species, we explored the motif mismatches patterns of microsatellites in birds on a genomic level and assessed the relationship between motif mismatches and body mass in a phylogenetic context. We found that small-bodied species have a higher average mismatches and we suggested that higher heterozygosity in imperfect microsatellites lead to the increase of motif mismatches. Our results obtained from this study imply that a negative body mass trend in mutation rate may be a general pattern of avian molecular evolution. PMID- 29576966 TI - Distribution and seasonal differences in Pacific Lamprey and Lampetra spp eDNA across 18 Puget Sound watersheds. AB - Lampreys have a worldwide distribution, are functionally important to ecological communities and serve significant roles in many cultures. In Pacific coast drainages of North America, lamprey populations have suffered large declines. However, lamprey population status and trends within many areas of this region are unknown and such information is needed for advancing conservation goals. We developed two quantitative PCR-based, aquatic environmental DNA (eDNA) assays for detection of Pacific Lamprey (Entosphenus tridentatus) and Lampetra spp, using locked nucleic acids (LNAs) in the probe design. We used these assays to characterize the spatial distribution of lamprey in 18 watersheds of Puget Sound, Washington, by collecting water samples in spring and fall. Pacific Lamprey and Lampetra spp were each detected in 14 watersheds and co-occurred in 10 watersheds. Lamprey eDNA detection rates were much higher in spring compared to fall. Specifically, the Pacific Lamprey eDNA detection rate was 3.5 times higher in spring and the Lampetra spp eDNA detection rate was 1.5 times higher in spring even though larval lamprey are present in streams year-round. This significant finding highlights the importance of seasonality on eDNA detection. Higher stream discharge in the fall likely contributed to reduced eDNA detection rates, although seasonal life history events may have also contributed. These eDNA assays differentiate Pacific Lamprey and Lampetra spp across much of their range along the west coast of North America. Sequence analysis indicates the Pacific Lamprey assay also targets other Entosphenus spp and indicates the Lampetra spp assay may have limited or no capability of detecting Lampetra in some locations south of the Columbia River Basin. Nevertheless, these assays will serve as a valuable tool for resource managers and have direct application to lamprey conservation efforts, such as mapping species distributions, occupancy modeling, and monitoring translocations and reintroductions. PMID- 29576967 TI - Prognostic value of new-onset right bundle-branch block in acute myocardial infarction patients: a systematic review and meta-analysis. AB - Background: Patients with acute myocardial infarction (AMI) and bundle-branch block have poor prognoses. The new European Society of Cardiology guideline suggests a primary percutaneous coronary intervention strategy when persistent ischemic symptoms occur in patients with persistent ischemic symptoms and right bundle-branch block (RBBB), but the level of evidence is not high. In fact, the presence of RBBB may lead to the misdiagnosis of transmural ischemia and mask the early diagnosis of ST-elevation myocardial infarction. Moreover, new-onset RBBB is occasionally caused by AMI. Our study aims to investigate the prognostic value of new-onset RBBB in AMI. Methods and Results: We conducted a meta-analysis of studies to evaluate the prognostic value of RBBB in AMI patients. Of 914 primary records, five studies and 874 MI patients were included for meta-analysis. Compared with previous RBBB, AMI patients with new-onset RBBB had a higher risk of long-term mortality (RR, 1.66, 95% CI [1.31-2.09], I2 = 0.0%, p = 0.000, n = 2), ventricular arrhythmia (RR, 4.86, 95% CI [2.10-11.27], I2 = 0.0%, p = 0.000, n = 3), and cardiogenic shock (RR, 2.76, 95% CI [1.66-4.59], I2 = 0.0%, p = 0.000, n = 3), but a lower risk of heart failure (RR, 0.66, 95% CI [0.52-0.85], I2 = 2.50%, p = 0.001, n = 4). Compared with AMI patients with new-onset permanent RBBB, patients with new-onset transient RBBB had a lower risk of short term mortality (RR, 0.20, 95% CI [0.11-0.37], I2 = 44.1%, p = 0.000, n = 4). Conclusion: New-onset RBBB is likely to increase long-term mortality, ventricular arrhythmia, and cardiogenic shock, but not heart failure in AMI patients. AMI patients with new-onset transient RBBB have a lower risk of short-term mortality than those with new-onset permanent RBBB. Revascularization therapies should be considered when persistent ischemic symptoms occur in patients with RBBB, especially new-onset RBBB. PMID- 29576968 TI - Assessing universality of DNA barcoding in geographically isolated selected desert medicinal species of Fabaceae and Poaceae. AB - In pursuit of developing fast and accurate species-level molecular identification methods, we tested six DNA barcodes, namely ITS2, matK, rbcLa, ITS2+matK, ITS2+rbcLa, matK+rbcLa and ITS2+matK+rbcLa, for their capacity to identify frequently consumed but geographically isolated medicinal species of Fabaceae and Poaceae indigenous to the desert of Cholistan. Data were analysed by BLASTn sequence similarity, pairwise sequence divergence in TAXONDNA, and phylogenetic (neighbour-joining and maximum-likelihood trees) methods. Comparison of six barcode regions showed that ITS2 has the highest number of variable sites (209/360) for tested Fabaceae and (106/365) Poaceae species, the highest species level identification (40%) in BLASTn procedure, distinct DNA barcoding gap, 100% correct species identification in BM and BCM functions of TAXONDNA, and clear cladding pattern with high nodal support in phylogenetic trees in both families. ITS2+matK+rbcLa followed ITS2 in its species-level identification capacity. The study was concluded with advocating the DNA barcoding as an effective tool for species identification and ITS2 as the best barcode region in identifying medicinal species of Fabaceae and Poaceae. Current research has practical implementation potential in the fields of pharmaco-vigilance, trade of medicinal plants and biodiversity conservation. PMID- 29576969 TI - Identification of circularRNAs and their targets in Gossypium under Verticillium wilt stress based on RNA-seq. AB - Circular RNAs (circRNAs), a class of recently discovered non-coding RNAs, play a role in biological and developmental processes. A recent study showed that circRNAs exist in plants and play a role in their environmental stress responses. However, cotton circRNAs and their role in Verticillium wilt response have not been identified up to now. In this study, two CSSLs (chromosome segment substitution lines) of G.barbadense introgressed into G. hirsutum, CSSL-1 and CSSL-4 (a resistant line and a susceptible line to Verticillium wilt, respectively), were inoculated with V. dahliae for RNA-seq library construction and circRNA analysis. A total of 686 novel circRNAs were identified. CSSL-1 and CSSL-4 had similar numbers of circRNAs and shared many circRNAs in common. However, CSSL-4 differentially expressed approximately twice as many circRNAs as CSSL-1, and the differential expression levels of the common circRNAs were generally higher in CSSL-1 than in CSSL-4. Moreover, two C-RRI comparisons, C-RRI vs-C-RRM and C-RRI-vs-C-RSI, possessed a large proportion (approximately 50%) of the commonly and differentially expressed circRNAs. These results indicate that the differentially expressed circRNAs may play roles in the Verticillium wilt response in cotton. A total of 280 differentially expressed circRNAs were identified. A Gene Ontology analysis showed that most of the 'stimulus response' term source genes were NBS family genes, of which most were the source genes from the differentially expressed circRNAs, indicating that NBS genes may play a role in Verticillium wilt resistance and might be regulated by circRNAs in the disease resistance process in cotton. PMID- 29576970 TI - Repetitive low intensity magnetic field stimulation in a neuronal cell line: a metabolomics study. AB - Low intensity repetitive magnetic stimulation of neural tissue modulates neuronal excitability and has promising therapeutic potential in the treatment of neurological disorders. However, the underpinning cellular and biochemical mechanisms remain poorly understood. This study investigates the behavioural effects of low intensity repetitive magnetic stimulation (LI-rMS) at a cellular and biochemical level. We delivered LI-rMS (10 mT) at 1 Hz and 10 Hz to B50 rat neuroblastoma cells in vitro for 10 minutes and measured levels of selected metabolites immediately after stimulation. LI-rMS at both frequencies depleted selected tricarboxylic acid (TCA) cycle metabolites without affecting the main energy supplies. Furthermore, LI-rMS effects were frequency-specific with 1 Hz stimulation having stronger effects than 10 Hz. The observed depletion of metabolites suggested that higher spontaneous activity may have led to an increase in GABA release. Although the absence of organised neural circuits and other cellular contributors (e.g., excitatory neurons and glia) in the B50 cell line limits the degree to which our results can be extrapolated to the human brain, the changes we describe provide novel insights into how LI-rMS modulates neural tissue. PMID- 29576972 TI - Recalibrating the body: visuotactile ventriloquism aftereffect. AB - Visuotactile ventriloquism is a recently reported effect showing that somatotopic tactile representations (namely, representation of location along the surface of one's arm) can be biased by simultaneous presentation of a visual stimulus in a spatial localization task along the surface of the skin. Here we investigated whether the exposure to discrepancy between tactile and visual stimuli on the skin can induce lasting changes in the somatotopic representations of space. We conducted an experiment investigating this question by asking participants to perform a localization task that included unisensory and bisensory trials, before and after exposure to spatially discrepant visuotactile stimuli. Participants localized brief flashes of light and brief vibrations that were presented along the surface of their forearms, and were presented either individually (unisensory conditions) or were presented simultaneously at the same location or different locations. We then compared the localization of tactile stimuli in unisensory tactile conditions before and after the exposure to discrepant bisensory stimuli. After exposure, participants exhibited a shift in their tactile localizations in the direction of the visual stimulus that was presented during the exposure block. These results demonstrate that the somatotopic spatial representations are capable of rapidly recalibrating after a very brief exposure to visually discrepant stimuli. PMID- 29576971 TI - Characterization of the basic helix-loop-helix gene family and its tissue differential expression in response to salt stress in poplar. AB - The basic helix-loop-helix (bHLH) transcription factor gene family is one of the largest gene families and extensively involved in plant growth, development, and stress responses. However, limited studies are available on the gene family in poplar. In this study, we focused on 202 bHLH genes, exploring their DNA and protein sequences and physicochemical properties. According to their protein sequence similarities, we classified the genes into 25 groups with specific motif structures. In order to explore their expressions, we performed gene expression profiling using RNA-Seq and identified 19 genes that display tissue-differential expression patterns without treatment. Furthermore, we also performed gene expression profiling under salt stress. We found 74 differentially expressed genes (DEGs), which are responsive to the treatment. A total of 18 of the 19 genes correspond well to the DEGs. We validated the results using reverse transcription quantitative real-time PCR. This study lays the foundation for future studies on gene cloning, transgenes, and biological mechanisms. PMID- 29576973 TI - Gender disparities in the association between socio-demographics and non communicable disease risk factors among adults with disabilities in Shanghai, China. AB - Background: Non-communicable disease (NCD) risk factors can co-exist with disability and cause a greater burden on the health status of adults with disabilities. A lack of egalitarian social policies in China may result in gender disparities in the NCD risk factors of adults with disabilities. However, little is known about the gender disparities in the association between socio demographics and NCD risk factors among adults with disabilities in China; consequently, we examined this association among adults with disabilities in Shanghai, China. Methods: We used the health examination data of 44,896 adults with disabilities in Shanghai in 2014. Descriptive analyses and logistic regression models were conducted to estimate gender disparities in the association between socio-demographics, disability characteristics, and four selected NCD risk factors among adults with disabilities-including high blood pressure, high blood glucose, high blood lipids, and being overweight. We estimated marginal effects (MEs) on NCD risk factors between gender and other confounders. Results: Women with disabilities were about 11.6 percentage points more likely to suffer from high blood lipids and less likely to develop the other three risk factors than men were. The association of age group, residence permit, education level, marital status, and disability type with health outcomes varied by gender among adults with disabilities. The difference in age effects between men and women was more pronounced in older age groups. Urban residence was associated with less risk of high blood pressure risk among women (DeltaME = - 0.035, p < 0.01), but no significant difference in other NCD risk factors. Education remained a major protective factor against high blood pressure, high blood glucose and being overweight among women with disabilities (MEs < 0, p < 0.05); however, this did not hold for men. The difference in marriage effects between men and women was observed in high blood lipids (DeltaME = - 0.048 for the married group and -0.054 for the divorced or widowed group) and overweight individuals (DeltaME = - 0.091 for the married group and -0.114 for the divorced or widowed group). Women with intellectual disabilities or mental disabilities reported worse health conditions than men did. Discussion: Preventive strategies and interventions on NCD risk factors for adults with disabilities should take into account gender disparities in these socio-demographic effects. Rural women or poorly educated women with disabilities can be a vulnerable population that requires more health education and promotion strategies. Health education for caregivers of women with intellectual or mental disabilities may also play a vital role in preventing their NCD risk factors. PMID- 29576974 TI - Searching the Internet for psychiatric disorders among Arab and Jewish Israelis: insights from a comprehensive infodemiological survey. AB - Israel represents a complex and pluralistic society comprising two major ethno national groups, Israeli Jews and Israeli Arabs, which differ in terms of religious and cultural values as well as social constructs. According to the so called "diversification hypothesis", within the framework of e-health and in the era of new information and communication technologies, seeking online health information could be a channel to increase health literacy, especially among disadvantaged groups. However, little is known concerning digital seeking behavior and, in particular, digital mental health literacy. This study was conducted in order to fill in this gap. Concerning raw figures, unadjusted for confounding variables (time, population size, Internet penetration index, disease rate), "depression" searched in Hebrew was characterized by 1.5 times higher search volumes, slightly declining throughout time, whereas relative search volumes (RSVs) related to "depression" searched in Arabic tended to increase over the years. Similar patterns could be detected for "phobia" (in Hebrew 1.4-fold higher than in Arabic) and for "anxiety" (with the searches performed in Hebrew 2.3 times higher than in Arabic). "Suicide" in Hebrew was searched 2.0-fold more than in Arabic (interestingly for both languages search volumes exhibited seasonal cyclic patterns). Eating disorders were searched more in Hebrew: 8.0 times more for "bulimia", whilst "anorexia" was searched in Hebrew only. When adjusting for confounding variables, association between digital seeking behavior and ethnicity remained statistically significant (p-value < 0.0001) for all psychiatric disorders considered in the current investigation, except for "bulimia" (p = 0.989). More in details, Israeli Arabs searched for mental health disorders less than Jews, apart from "depression". Arab and Jewish Israelis, besides differing in terms of language, religion, social and cultural values, have different patterns of usage of healthcare services and provisions, as well as e-healthcare services concerning mental health. Policy- and decision-makers should be aware of this and make their best efforts to promote digital health literacy among the Arab population in Israel. PMID- 29576977 TI - Seasonal temperature acclimatization in a semi-fossorial mammal and the role of burrows as thermal refuges. AB - Small mammals in habitats with strong seasonal variation in the thermal environment often exhibit physiological and behavioral adaptations for coping with thermal extremes and reducing thermoregulatory costs. Burrows are especially important for providing thermal refuge when above-ground temperatures require high regulatory costs (e.g., water or energy) or exceed the physiological tolerances of an organism. Our objective was to explore the role of burrows as thermal refuges for a small endotherm, the pygmy rabbit (Brachylagus idahoensis), during the summer and winter by quantifying energetic costs associated with resting above and below ground. We used indirect calorimetry to determine the relationship between energy expenditure and ambient temperature over a range of temperatures that pygmy rabbits experience in their natural habitat. We also measured the temperature of above- and below-ground rest sites used by pygmy rabbits in eastern Idaho, USA, during summer and winter and estimated the seasonal thermoregulatory costs of resting in the two microsites. Although pygmy rabbits demonstrated seasonal physiological acclimatization, the burrow was an important thermal refuge, especially in winter. Thermoregulatory costs were lower inside the burrow than in above-ground rest sites for more than 50% of the winter season. In contrast, thermal heterogeneity provided by above-ground rest sites during summer reduced the role of burrows as a thermal refuge during all but the hottest periods of the afternoon. Our findings contribute to an understanding of the ecology of small mammals in seasonal environments and demonstrate the importance of burrows as thermal refuge for pygmy rabbits. PMID- 29576976 TI - Proteomic identification of galectin-11 and 14 ligands from Haemonchus contortus. AB - Haemonchus contortus is the most pathogenic nematode of small ruminants. Infection in sheep and goats results in anaemia that decreases animal productivity and can ultimately cause death. The involvement of ruminant-specific galectin-11 (LGALS-11) and galectin-14 (LGALS-14) has been postulated to play important roles in protective immune responses against parasitic infection; however, their ligands are unknown. In the current study, LGALS-11 and LGALS-14 ligands in H. contortus were identified from larval (L4) and adult parasitic stages extracts using immobilised LGALS-11 and LGALS-14 affinity column chromatography and mass spectrometry. Both LGALS-11 and LGALS-14 bound more putative protein targets in the adult stage of H. contortus (43 proteins) when compared to the larval stage (two proteins). Of the 43 proteins identified in the adult stage, 34 and 35 proteins were bound by LGALS-11 and LGALS-14, respectively, with 26 proteins binding to both galectins. Interestingly, hematophagous stage-specific sperm-coating protein and zinc metalloprotease (M13), which are known vaccine candidates, were identified as putative ligands of both LGALS-11 and LGALS-14. The identification of glycoproteins of H. contortus by LGALS-11 and LGALS-14 provide new insights into host-parasite interactions and the potential for developing new interventions. PMID- 29576975 TI - Half-lives of PAHs and temporal microbiota changes in commonly used urban landscaping materials. AB - Background: Polycyclic aromatic hydrocarbons (PAHs) accumulate in urban soils, and PAH contamination can change soil microbial community composition. Environmental microbiota is associated with human commensal microbiota, immune system and health. Therefore, studies investigating the degradation of PAHs, and the consequences of soil pollution on microbial communities in urban landscaping materials, are crucial. Methods: Four landscaping materials (organic matter 1, 2, 13 and 56%) were contaminated with PAHs commonly found at urban sites (phenanthrene, fluoranthene, pyrene, chrysene and benzo(b)fluoranthene) in PAH concentrations that reflect urban soils in Finland (2.4 ug g -1 soil dry weight). PAHs were analyzed initially and after 2, 4, 8 and 12 weeks by gas chromatography mass spectrometry. Half-lives of PAHs were determined based on 12-weeks degradation. Bacterial communities were analyzed at 1 and 12 weeks after contamination using Illumina MiSeq 16S rRNA gene metabarcoding. Results: Half lives ranged from 1.5 to 4.4 weeks for PAHs with relatively low molecular weights (phenanthrene, fluoranthene and pyrene) in landscaping materials containing 1-2% organic matter. In contrast, in materials containing 13% and 56% organic matter, the half-lives ranged from 2.5 to 52 weeks. Shorter half-lives of phenanthrene and fluoranthene were thus associated with low organic matter content. The half life of pyrene was inversely related to the relative abundance of Beta-, Delta- and Gammaproteobacteria, and diversity of Bacteroidetes and Betaprotebacteria. Compounds with higher molecular weights followed compound-specific patterns. Benzo(b)fluoranthene was resistant to degradation and half-life of chrysene was shorter when the relative abundance of Betaproteobacteria was high. Temporal microbiota changes involved increase in the relative abundance of Deltaproteobacteria and decrease in genera Flavobacterium and Rhodanobacter. Exposure to PAHs seems to adjust microbial community composition, particularly within class Beta- and Deltaproteobacteria. Conclusions: In this study, PAH degradation depended on the organic matter content and bacterial community composition of landscaping materials. Contamination seems to alter bacterial community composition in landscaping materials depending on material type. This alteration includes changes in bacterial phyla associated with human health and immune system. This may open new possibilities for managing urban environments by careful selection of landscaping materials, to benefit health and wellbeing. PMID- 29576978 TI - Escaping and repairing behaviors of the termite Odontotermes formosanus (Blattodea: Termitidae) in response to disturbance. AB - The escaping behavior of termites has been documented under laboratory conditions; however, no study has been conducted in a field setting due to the difficulty of observing natural behaviors inside wood or structures (e.g., nests, tunnels, etc.). The black-winged termite, Odontotermes formosanus (Shiraki), is a subterranean macrotermitine species which builds extensive mud tubes on tree trunks. In the present study, 41 videos (totaling ~2,700 min) were taken on 22 colonies/subcolonies of O. formosanus after their mud tubes were partially damaged by hand. In general, termites consistently demonstrated three phases of escape, including initiation (wandering near the mud-tube breach), individual escaping (single termites moving downward), and massive, unidirectional escaping flows (groups of termites moving downward). Downward moving and repairing were the dominant behavioral activities of individuals and were significantly more frequent than upward moving, turning/backward moving, or wandering. Interestingly, termites in escaping flows moved significantly faster than escaping individuals. Repairing behavior was observed shortly after the disturbance, and new mud tubes were preferentially constructed from the bottom up. When predators (i.e., ants) were present, however, termites stopped moving and quickly sealed the mud-tube openings by capping the broken ends. Our study provides an interesting example that documents an animal (besides humans) simultaneously carrying out pathway repairs and emergency evacuation without congestion. PMID- 29576979 TI - Assessing soil bacterial community and dynamics by integrated high-throughput absolute abundance quantification. AB - Microbial ecological studies have been remarkably promoted by the high-throughput sequencing approach with explosive information of taxonomy and relative abundance. However, relative abundance does not reflect the quantity of the microbial community and the inter-sample differences among taxa. In this study, we refined and applied an integrated high-throughput absolute abundance quantification (iHAAQ) method to better characterize soil quantitative bacterial community through combining the relative abundance (by high-throughput sequencing) and total bacterial quantities (by quantitative PCR). The proposed iHAAQ method was validated by an internal reference strain EDL933 and a laboratory strain WG5. Application of the iHAAQ method to a soil phenanthrene biodegradation study showed that for some bacterial taxa, the changes of relative and absolute abundances were coincident, while for others the changes were opposite. With the addition of a microbial activity inhibitor (NaN3), the absolute abundances of soil bacterial taxa, including several dominant genera of Bacillus, Flavobacterium, and Paenibacillus, decreased significantly, but their relative abundances increased after 28 days of incubation. We conclude that the iHAAQ method can offer more comprehensive information to reflect the dynamics of soil bacterial community with both relative and absolute abundances than the relative abundance from high-throughput sequencing alone. PMID- 29576980 TI - The right thalamus may play an important role in anesthesia-awakening regulation in frogs. AB - Background: Previous studies have shown that the mammalian thalamus is a key structure for anesthesia-induced unconsciousness and anesthesia-awakening regulation. However, both the dynamic characteristics and probable lateralization of thalamic functioning during anesthesia-awakening regulation are not fully understood, and little is known of the evolutionary basis of the role of the thalamus in anesthesia-awakening regulation. Methods: An amphibian species, the South African clawed frog (Xenopus laevis) was used in the present study. The frogs were immersed in triciane methanesulfonate (MS-222) for general anesthesia. Electroencephalogram (EEG) signals were recorded continuously from both sides of the telencephalon, diencephalon (thalamus) and mesencephalon during the pre anesthesia stage, administration stage, recovery stage and post-anesthesia stage. EEG data was analyzed including calculation of approximate entropy (ApEn) and permutation entropy (PE). Results: Both ApEn and PE values differed significantly between anesthesia stages, with the highest values occurring during the awakening period and the lowest values during the anesthesia period. There was a significant correlation between the stage durations and ApEn or PE values during anesthesia-awakening cycle primarily for the right diencephalon (right thalamus). ApEn and PE values for females were significantly higher than those for males. Discussion: ApEn and PE measurements are suitable for estimating depth of anesthesia and complexity of amphibian brain activity. The right thalamus appears physiologically positioned to play an important role in anesthesia-awakening regulation in frogs indicating an early evolutionary origin of the role of the thalamus in arousal and consciousness in land vertebrates. Sex differences exist in the neural regulation of general anesthesia in frogs. PMID- 29576981 TI - Large-scale assessment of commensalistic-mutualistic associations between African birds and herbivorous mammals using internet photos. AB - Birds sitting or feeding on live large African herbivorous mammals are a visible, yet quite neglected, type of commensalistic-mutualistic association. Here, we investigate general patterns in such relationships at large spatial and taxonomic scales. To obtain large-scale data, an extensive internet-based search for photos was carried out on Google Images. To characterize patterns of the structural organization of commensalistic-mutualistic associations between African birds and herbivorous mammals, we used a network analysis approach. We then employed phylogenetically-informed comparative analysis to explore whether features of bird visitation of mammals, i.e., their mean number, mass and species richness per mammal species, are shaped by a combination of host mammal (body mass and herd size) and environmental (habitat openness) characteristics. We found that the association web structure was only weakly nested for commensalistic as well as for mutualistic birds (oxpeckers Buphagus spp.) and African mammals. Moreover, except for oxpeckers, nestedness did not differ significantly from a null model indicating that birds do not prefer mammal species which are visited by a large number of bird species. In oxpeckers, however, a nested structure suggests a non random assignment of birds to their mammal hosts. We also identified some new or rare associations between birds and mammals, but we failed to find several previously described associations. Furthermore, we found that mammal body mass positively influenced the number and mass of birds observed sitting on them in the full set of species (i.e., taking oxpeckers together with other bird species). We also found a positive correlation between mammal body mass and mass of non-oxpecker species as well as oxpeckers. Mammal herd size was associated with a higher mass of birds in the full set of species as well as in non-oxpecker species, and mammal species living in larger herds also attracted more bird species in the full set of species. Habitat openness influenced the mass of birds sitting on mammals as well as the number of species recorded sitting on mammals in the full set of species. In non-oxpecker species habitat openness was correlated with the bird number, mass and species richness. Our results provide evidence that patterns of bird-mammal associations can be linked to mammal and environmental characteristics and highlight the potential role of information technologies and new media in further studies of ecology and evolution. However, further study is needed to get a proper insight into the biological and methodological processes underlying the observed patterns. PMID- 29576982 TI - The effect of tides on nearshore environmental DNA. AB - We can recover genetic information from organisms of all kinds using environmental sampling. In recent years, sequencing this environmental DNA (eDNA) has become a tractable means of surveying many species using water, air, or soil samples. The technique is beginning to become a core tool for ecologists, environmental scientists, and biologists of many kinds, but the temporal resolution of eDNA sampling is often unclear, limiting the ecological interpretations of the resulting datasets. Here, in a temporally and spatially replicated field study using ca. 313 bp of eukaryotic COI mtDNA as a marker, we find that nearshore organismal communities are largely consistent across tides. Our findings suggest that nearshore eDNA from both benthic and planktonic taxa tends to be endogenous to the site and water mass sampled, rather than changing with each tidal cycle. However, where physiochemical water mass characteristics change, we find that the relative contributions of a broad range of organisms to eDNA communities shift in concert.

AB - Background: There is a lack of research considering acute fatigue responses to high- and low-load resistance training as well as the comparison between male and female responses. Furthermore, limited studies have considered fatigue response testing with the inclusion of perceptions of discomfort and exertion. Methods: The present study included males (n = 9; 23.8 +/- 6.4 years; 176.7 +/- 6.2 cm; 73.9 +/- 9.3 kg) and females (n = 8; 21.3 +/- 0.9 years; 170.5 +/- 6.1 cm; 65.5 +/- 10.8 kg) who were assessed for differences in fatigue (i.e., loss of torque at maximal voluntary contraction (MVC)) immediately following isolated lumbar extension (ILEX) exercise at heavy- (HL) and light-(LL) loads (80% and 50% MVC, respectively). Participants also reported perceptual measures of effort (RPE-E) and discomfort (RPE-D) between different resistance training protocols. Results: Analysis of variance revealed significantly greater absolute and relative fatigue following LL compared to HL conditions (p < 0.001). Absolute fatigue significantly differed between males and females (p = 0.012), though relative fatigue was not significantly different (p = 0.160). However, effect sizes for absolute fatigue (HL; Males = -1.84, Females = -0.83; LL; Males = -3.11, Females = -2.39) and relative fatigue (HL; Males = -2.17, Females = -0.76; LL; Males = 3.36, Females = -3.08) were larger for males in both HL and LL conditions. RPE-E was maximal for all participants in both conditions, but RPE-D was significantly higher in LL compared to HL (p < 0.001) with no difference between males and females. Discussion: Our data suggests that females do not incur the same degree of fatigue as males following similar exercise protocols, and indeed that females might be able to sustain longer exercise duration at the same relative loads. As such females should manipulate training variables accordingly, perhaps performing greater repetitions at a relative load, or using heavier relative loads than males. Furthermore, since lighter load exercise is often prescribed in rehabilitation settings (particularly for the lumbar extensors) it seems prudent to know that this might not be necessary to strengthen musculature and indeed might be contraindicated to avoid the increased fatigue and discomfort associated with LL exercise.

AB - The Hawaiian Islands offer a unique opportunity to test how changes in the properties of an isolated ecosystem are propagated through the organisms that occur within that ecosystem. The age-structured arrangement of volcanic-derived substrates follows a regular progression over space and, by inference, time. We test how well documented successional changes in soil chemistry and associated vegetation are reflected in organisms at higher trophic levels-specifically, predatory arthropods (spiders)-across a range of functional groups. We focus on three separate spider lineages: one that builds capture webs, one that hunts actively, and one that specializes on eating other spiders. We analyze spiders from three sites across the Hawaiian chronosequence with substrate ages ranging from 200 to 20,000 years. To measure the extent to which chemical signatures of terrestrial substrates are propagated through higher trophic levels, we use standard stable isotope analyses of nitrogen and carbon, with plant leaves included as a baseline. The target taxa show the expected shift in isotope ratios of delta15N with trophic level, from plants to cursorial spiders to web-builders to spider eaters. Remarkably, organisms at all trophic levels also precisely reflect the successional changes in the soil stoichiometry of the island chronosequence, demonstrating how the biogeochemistry of the entire food web is determined by ecosystem succession of the substrates on which the organisms have evolved. PMID- 29576985 TI - Influence of allelic variations in relation to norepinephrine and mineralocorticoid receptors on psychopathic traits: a pilot study. AB - Background: Past findings support a relationship between abnormalities in the amygdala and the presence of psychopathic traits. Among other genes and biomarkers relevant to the amygdala, norepinephrine and mineralocorticoid receptors might both play a role in psychopathy due to their association with traits peripheral to psychopathy. The purpose is to examine if allelic variations in single nucleotide polymorphisms related to norepinephrine and mineralocorticoid receptors play a role in the display of psychopathic traits and executive functions. Methods: Fifty-seven healthy participants from the community provided a saliva sample for SNP sampling of rs5522 and rs5569. Participants then completed the Psychopathic Personality Inventory-Short Form (PPI-SF) and the Tower of Hanoi. Results: Allelic variations of both rs5522 and rs5569 were significant when compared to PPI-SF total score and the fearless dominance component of the PPI-SF. A significant result was also obtained between rs5522 and the number of moves needed to complete the 5-disk Tower of Hanoi. Conclusion: This pilot study offers preliminary results regarding the effect of allelic variations in SNPs related to norepinephrine and mineralocorticoid receptors on the presence of psychopathic traits. Suggestions are provided to enhance the reliability and validity of a larger-scale study. PMID- 29576986 TI - The systematic position of the enigmatic thyreophoran dinosaur Paranthodon africanus, and the use of basal exemplifiers in phylogenetic analysis. AB - The first African dinosaur to be discovered, Paranthodon africanus was found in 1845 in the Lower Cretaceous of South Africa. Taxonomically assigned to numerous groups since discovery, in 1981 it was described as a stegosaur, a group of armoured ornithischian dinosaurs characterised by bizarre plates and spines extending from the neck to the tail. This assignment has been subsequently accepted. The type material consists of a premaxilla, maxilla, a nasal, and a vertebra, and contains no synapomorphies of Stegosauria. Several features of the maxilla and dentition are reminiscent of Ankylosauria, the sister-taxon to Stegosauria, and the premaxilla appears superficially similar to that of some ornithopods. The vertebral material has never been described, and since the last description of the specimen, there have been numerous discoveries of thyreophoran material potentially pertinent to establishing the taxonomic assignment of the specimen. An investigation of the taxonomic and systematic position of Paranthodon is therefore warranted. This study provides a detailed re description, including the first description of the vertebra. Numerous phylogenetic analyses demonstrate that the systematic position of Paranthodon is highly labile and subject to change depending on which exemplifier for the clade Stegosauria is used. The results indicate that the use of a basal exemplifier may not result in the correct phylogenetic position of a taxon being recovered if the taxon displays character states more derived than those of the basal exemplifier, and we recommend the use, minimally, of one basal and one derived exemplifier per clade. Paranthodon is most robustly recovered as a stegosaur in our analyses, meaning it is one of the youngest and southernmost stegosaurs. PMID- 29576987 TI - Conserving relics from ancient underground worlds: assessing the influence of cave and landscape features on obligate iron cave dwellers from the Eastern Amazon. AB - The degradation of subterranean habitats is believed to represent a serious threat for the conservation of obligate subterranean dwellers (troglobites), many of which are short-range endemics. However, while the factors influencing cave biodiversity remain largely unknown, the influence of the surrounding landscape and patterns of subterranean connectivity of terrestrial troglobitic communities have never been systematically assessed. Using spatial statistics to analyze the most comprehensive speleological database yet available for tropical caves, we first assess the influence of iron cave characteristics and the surrounding landscape on troglobitic communities from the Eastern Amazon. We then determine the spatial pattern of troglobitic community composition, species richness, phylogenetic diversity, and the occurrence of frequent troglobitic species, and finally quantify how different landscape features influence the connectivity between caves. Our results reveal the key importance of habitat amount, guano, water, lithology, geomorphology, and elevation in shaping iron cave troglobitic communities. While mining within 250 m from the caves influenced species composition, increasing agricultural land cover within 50 m from the caves reduced species richness and phylogenetic diversity. Troglobitic species composition, species richness, phylogenetic diversity, and the occurrence of frequent troglobites showed spatial autocorrelation for up to 40 km. Finally, our results suggest that the conservation of cave clusters should be prioritized, as geographic distance was the main factor determining connectivity between troglobitic communities. Overall, our work sheds important light onto one of the most overlooked terrestrial ecosystems, and highlights the need to shift conservation efforts from individual caves to subterranean habitats as a whole. PMID- 29576989 TI - The contribution of Earth observation technologies to the reporting obligations of the Habitats Directive and Natura 2000 network in a protected wetland. AB - Background: Wetlands are highly productive systems that supply a host of ecosystem services and benefits. Nonetheless, wetlands have been drained and filled to provide sites for building houses and roads and for establishing farmland, with an estimated worldwide loss of 64-71% of wetland systems since 1900. In Europe, the Natura 2000 network is the cornerstone of current conservation strategies. Every six years, Member States must report on implementation of the European Habitats Directive. The present study aims to illustrate how Earth observation (EO) technologies can contribute to the reporting obligations of the Habitats Directive and Natura 2000 network in relation to wetland ecosystems. Methods: We analysed the habitat changes that occurred in a protected wetland (in NW Spain), 13 years after its designation as Natura 2000 site (i.e., between 2003 and 2016). For this purpose, we analysed optical multispectral bands and water-related and vegetation indices derived from data acquired by Landsat 7 TM, ETM+ and Landsat 8 OLI sensors. To quantify the uncertainty arising from the algorithm used in the classification procedure and its impact on the change analysis, we compared the habitat change estimates obtained using 10 different classification algorithms and two ensemble classification approaches (majority and weighted vote). Results: The habitat maps derived from the ensemble approaches showed an overall accuracy of 94% for the 2003 data (Kappa index of 0.93) and of 95% for the 2016 data (Kappa index of 0.94). The change analysis revealed important temporal dynamics between 2003 and 2016 for the habitat classes identified in the study area. However, these changes depended on the classification algorithm used. The habitat maps obtained from the two ensemble classification approaches showed a reduction in habitat classes dominated by salt marshes and meadows (24.6-26.5%), natural and semi-natural grasslands (25.9-26.5%) or sand dunes (20.7-20.9%) and an increase in forest (31 34%) and reed bed (60.7-67.2%) in the study area. Discussion: This study illustrates how EO-based approaches might be particularly useful to help (1) managers to reach decisions in relation to conservation, (2) Member States to comply with the requirements of the European Habitats Directive (92/43/EEC), and (3) the European Commission to monitor the conservation status of the natural habitat types of community interest listed in Annex I of the Directive. Nonetheless, the uncertainty arising from the large variety of classification methods used may prevent local managers from basing their decisions on EO data. Our results shed light on how different classification algorithms may provide very different quantitative estimates, especially for water-dependent habitats. Our findings confirm the need to account for this uncertainty by applying ensemble classification approaches, which improve the accuracy and stability of remote sensing image classification. PMID- 29576988 TI - Tea saponin reduces the damage of Ectropis obliqua to tea crops, and exerts reduced effects on the spiders Ebrechtella tricuspidata and Evarcha albaria compared to chemical insecticides. AB - Background: Tea is one of the most economically important crops in China. However, the tea geometrid (Ectropis obliqua), a serious leaf-feeding pest, causes significant damage to tea crops and reduces tea yield and quality. Spiders are the most dominant predatory enemies in the tea plantation ecosystem, which makes them potentially useful biological control agents of E. obliqua. These highlight the need for alternative pest control measures. Our previous studies have shown that tea saponin (TS) exerts insecticidal activity against lepidopteran pests. Here, we investigate whether TS represents a potentially new alternative insecticide with no harm to spiders. Methods: We investigated laboratory bioactivities and the field control properties of TS solution against E. obliqua. (i) A leaf-dip bioassay was used to evaluate the toxicity of TS to 3rd-instar E. obliqua larvae and effects of TS on the activities of enzymes glutathione-S-transferase (GST), acetylcholinesterase (AChE), carboxylesterase (CES) and peroxidase (POD) of 3rd-instar E. obliqua larvae in the laboratory. (ii) Topical application was used to measure the toxicity of 30% TS (w/v) and two chemical insecticides (10% bifenthrin EC and 50% diafenthiuron SC) to two species of spider, Ebrechtella tricuspidata and Evarcha albaria. (iii) Field trials were used to investigate the controlling efficacy of 30% TS against E. obliqua larvae and to classify the effect of TS to spiders in the tea plantation. Results: The toxicity of TS to 3rd-instar E. obliqua larvae occurred in a dose-dependent manner and the LC50 was 164.32 mg/mL. Activities of the detoxifying-related enzymes, GST and POD, increased in 3rd-instar E. obliqua larvae, whereas AChE and CES were inhibited with time by treatment with TS. Mortalities of E. tricuspidata and E. albaria after 48 h with 30% TS treatment (16.67% and 20%, respectively) were significantly lower than those with 10% bifenthrin EC (80% and 73.33%, respectively) and 50% diafenthiuron EC (43.33% and 36.67%, respectively). The highest controlling efficacy of 30% TS was 77.02% at 5 d after treatment, which showed no difference to 10% bifenthrin EC or 50% diafenthiuron SC. 30% TS was placed in the class N (harmless or slightly harmful) of IOBC (International Organization of Biological Control) categories for natural enemies, namely spiders. Conclusions: Our results indicate that TS is a botanical insecticide that has a good controlling efficacy in E. obliqua larvae, which suggests it has promise as application in the integrated pest management (IPM) envisaged for tea crops. PMID- 29576990 TI - Necessity of electrically conductive pili for methanogenesis with magnetite stimulation. AB - Background: Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments. Although magnetite-mediated DIET has been documented in defined co cultures reducing fumarate or nitrate as the electron acceptor, the effects of magnetite have only been inferred in methanogenic systems. Methods: Concentrations of methane and organic acid were analysed with a gas chromatograph and high-performance liquid chromatography, respectively. The concentration of HCl-extractable Fe(II) was determined by the ferrozine method. The association of the defined co-cultures of G. metallireducens and M. barkeri with magnetite was observed with transmission electron micrographs. Results: Magnetite stimulated ethanol metabolism and methane production in defined co-cultures of G. metallireducens and M. barkeri; however, magnetite did not promote methane production in co-cultures initiated with a culture of G. metallireducens that could not produce electrically conductive pili (e-pili), unlike the conductive carbon materials that facilitate DIET in the absence of e-pili. Transmission electron microscopy revealed that G. metallireducens and M. barkeri were closely associated when magnetite was present, as previously observed in G. metallireducens/G. sulfurreducens co-cultures. These results show that magnetite can promote DIET between Geobacter and Methanosarcina species, but not as a substitute for e-pili, and probably functions to facilitate electron transfer from the e-pili to Methanosarcina. Conclusion: In summary, the e-pili are necessary for the stimulation of not only G. metallireducens/G. sulfurreducens, but also methanogenic G. metallireducens/M. barkeri co-cultures with magnetite. PMID- 29576991 TI - Cenozoic aridization in Central Eurasia shaped diversification of toad-headed agamas (Phrynocephalus; Agamidae, Reptilia). AB - We hypothesize the phylogenetic relationships of the agamid genus Phrynocephalus to assess how past environmental changes shaped the evolutionary and biogeographic history of these lizards and especially the impact of paleogeography and climatic factors. Phrynocephalus is one of the most diverse and taxonomically confusing lizard genera. As a key element of Palearctic deserts, it serves as a promising model for studies of historical biogeography and formation of arid habitats in Eurasia. We used 51 samples representing 33 of 40 recognized species of Phrynocephalus covering all major areas of the genus. Molecular data included four mtDNA (COI, ND2, ND4, Cytb; 2,703 bp) and four nuDNA protein-coding genes (RAG1, BDNF, AKAP9, NKTR; 4,188 bp). AU-tests were implemented to test for significant differences between mtDNA- and nuDNA-based topologies. A time-calibrated phylogeny was estimated using a Bayesian relaxed molecular clock with nine fossil calibrations. We reconstructed the ancestral area of origin, biogeographic scenarios, body size, and the evolution of habitat preference. Phylogenetic analyses of nuDNA genes recovered a well-resolved and supported topology. Analyses detected significant discordance with the less supported mtDNA genealogy. The position of Phrynocephalus mystaceus conflicted greatly between the two datasets. MtDNA introgression due to ancient hybridization best explained this result. Monophyletic Phrynocephalus contained three main clades: (I) oviparous species from south-western and Middle Asia; (II) viviparous species of Qinghai-Tibetan Plateau (QTP); and (III) oviparous species of the Caspian Basin, Middle and Central Asia. Phrynocephalus originated in late Oligocene (26.9 Ma) and modern species diversified during the middle Miocene (14.8-13.5 Ma). The reconstruction of ancestral areas indicated that Phrynocephalus originated in Middle East-southern Middle Asia. Body size miniaturization likely occurred early in the history of Phrynocephalus. The common ancestor of Phrynocephalus probably preferred sandy substrates with the inclusion of clay or gravel. The time of Agaminae radiation and origin of Phrynocephalus in the late Oligocene significantly precedes the landbridge between Afro-Arabia and Eurasia in the Early Miocene. Diversification of Phrynocephalus coincides well with the mid-Miocene climatic transition when a rapid cooling of climate drove progressing aridification and the Paratethys salinity crisis. These factors likely triggered the spreading of desert habitats in Central Eurasia, which Phrynocephalus occupied. The origin of the viviparous Tibetan clade has been associated traditionally with uplifting of the QTP; however, further studies are needed to confirm this. Progressing late Miocene aridification, the decrease of the Paratethys Basin, orogenesis, and Plio Pleistocene climate oscillations likely promoted further diversification within Phrynocephalus. We discuss Phrynocephalus taxonomy in scope of the new analyses. PMID- 29576992 TI - High resolution crystal structures of the receptor-binding domain of Clostridium botulinum neurotoxin serotypes A and FA. AB - The binding specificity of botulinum neurotoxins (BoNTs) is primarily a consequence of their ability to bind to multiple receptors at the same time. BoNTs consist of three distinct domains, a metalloprotease light chain (LC), a translocation domain (HN) and a receptor-binding domain (HC). Here we report the crystal structure of HC/FA, complementing an existing structure through the modelling of a previously unresolved loop which is important for receptor binding. Our HC/FA structure also contains a previously unidentified disulphide bond, which we have also observed in one of two crystal forms of HC/A1. This may have implications for receptor-binding and future recombinant toxin production. PMID- 29576993 TI - New Insights about Cloud Vertical Structure from CloudSat and CALIPSO observations. AB - Active cloud observations from A-Train's CloudSat and CALIPSO satellites offer new opportunities to examine the vertical structure of hydrometeor layers. We use the 2B-CLDCLASS-LIDAR merged CloudSat-CALIPSO product to examine global aspects of hydrometeor vertical stratification. We group the data into major Cloud Vertical Structure (CVS) classes based on our interpretation of how clouds in three standard atmospheric layers overlap, and provide their global frequency of occurrence. The two most frequent CVS classes are single-layer (per our definition) low and high clouds which represent ~53% of cloudy skies, followed by high clouds overlying low clouds, and vertically extensive clouds that occupy near-contiguously a large portion of the troposphere. The prevalence of these configurations changes seasonally and geographically, between daytime and nighttime, and between continents and oceans. The radiative effects of the CVS classes reveal the major radiative warmers and coolers from the perspective of the planet as a whole, the surface, and the atmosphere. Single-layer low clouds dominate planetary and atmospheric cooling, and thermal infrared surface warming. We also investigate the consistency between passive and active views of clouds by providing the CVS breakdowns of MODIS cloud regimes for spatiotemporally coincident MODIS-Aqua (also on the A-Train) and CloudSat-CALIPSO daytime observations. When the analysis is expanded for a more in-depth look at the most heterogeneous of the MODIS cloud regimes, it ultimately confirms previous interpretations of their makeup that did not have the benefit of collocated active observations. PMID- 29576995 TI - Surface Connectivity and Interocean Exchanges From Drifter-Based Transition Matrices. AB - Global surface transport in the ocean can be represented by using the observed trajectories of drifters to calculate probability distribution functions. The oceanographic applications of the Markov Chain approach to modeling include tracking of floating debris and water masses, globally and on yearly-to centennial time scales. Here we analyze the error inherent with mapping trajectories onto a grid and the consequences for ocean transport modeling and detection of accumulation structures. A sensitivity analysis of Markov Chain parameters is performed in an idealized Stommel gyre and western boundary current as well as with observed ocean drifters, complementing previous studies on widespread floating debris accumulation. Focusing on two key areas of interocean exchange-the Agulhas system and the North Atlantic intergyre transport barrier-we assess the capacity of the Markov Chain methodology to detect surface connectivity and dynamic transport barriers. Finally, we extend the methodology's functionality to separate the geostrophic and nongeostrophic contributions to interocean exchange in these key regions. PMID- 29576994 TI - Gravity Wave Dynamics in a Mesospheric Inversion Layer: 1. Reflection, Trapping, and Instability Dynamics. AB - An anelastic numerical model is employed to explore the dynamics of gravity waves (GWs) encountering a mesosphere inversion layer (MIL) having a moderate static stability enhancement and a layer of weaker static stability above. Instabilities occur within the MIL when the GW amplitude approaches that required for GW breaking due to compression of the vertical wavelength accompanying the increasing static stability. Thus, MILs can cause large-amplitude GWs to yield instabilities and turbulence below the altitude where they would otherwise arise. Smaller-amplitude GWs encountering a MIL do not lead to instability and turbulence but do exhibit partial reflection and transmission, and the transmission is a smaller fraction of the incident GW when instabilities and turbulence arise within the MIL. Additionally, greater GW transmission occurs for weaker MILs and for GWs having larger vertical wavelengths relative to the MIL depth and for lower GW intrinsic frequencies. These results imply similar dynamics for inversions due to other sources, including the tropopause inversion layer, the high stability capping the polar summer mesopause, and lower frequency GWs or tides having sufficient amplitudes to yield significant variations in stability at large and small vertical scales. MILs also imply much stronger reflections and less coherent GW propagation in environments having significant fine structure in the stability and velocity fields than in environments that are smoothly varying. PMID- 29576996 TI - Scaling Properties of Arctic Sea Ice Deformation in a High-Resolution Viscous Plastic Sea Ice Model and in Satellite Observations. AB - Sea ice models with the traditional viscous-plastic (VP) rheology and very small horizontal grid spacing can resolve leads and deformation rates localized along Linear Kinematic Features (LKF). In a 1 km pan-Arctic sea ice-ocean simulation, the small-scale sea ice deformations are evaluated with a scaling analysis in relation to satellite observations of the Envisat Geophysical Processor System (EGPS) in the Central Arctic. A new coupled scaling analysis for data on Eulerian grids is used to determine the spatial and temporal scaling and the coupling between temporal and spatial scales. The spatial scaling of the modeled sea ice deformation implies multifractality. It is also coupled to temporal scales and varies realistically by region and season. The agreement of the spatial scaling with satellite observations challenges previous results with VP models at coarser resolution, which did not reproduce the observed scaling. The temporal scaling analysis shows that the VP model, as configured in this 1 km simulation, does not fully resolve the intermittency of sea ice deformation that is observed in satellite data. PMID- 29576997 TI - 5-Point programme for sustainable plant protection. AB - This position paper intends to stimulate a profound rethinking of contemporary agricultural practice. We criticise the current intensity of chemical plant protection in Germany as ecologically unsustainable and thus threatening the achievement of key targets of environmental protection and nature conservation policies. In the first part of the paper, we provide background information on the use of plant protection products (PPP) in German agriculture, the role of agricultural policy, European pesticide legislation, the principles of and framework for environmental risk assessment and risk management of PPP, as well as environmental effects of PPP. The second part is presented against the backdrop of the European "Sustainable Use Directive" (2009/128/EC). This directive requires that "Member States shall adopt National Action Plans to set up their quantitative objectives, targets, measures, and timetables to reduce risks and impacts of pesticide use on human health and the environment and to encourage the development and introduction of integrated pest management and of alternative approaches or techniques to reduce dependency on the use of pesticides." Reflecting on the corresponding debate in Germany, we suggest the following five key principles for a sustainable use of PPP and provide recommendations for their implementation: (1) minimising use; (2) identifying, quantifying, and communicating risks; (3) optimising risk management; (4) compensating for unavoidable effects; (5) internalising external costs. PMID- 29576998 TI - Integral approach of sorption coupled with biodegradation for treatment of azo dye using Pseudomonas sp.: batch, toxicity, and artificial neural network. AB - The present study investigated the removal of azo dye (crystal violet) by adsorption (using a low-cost adsorbent fly ash), biodegradation (using bacterial species, Pseudomonas sp.), and an integrated approach of sorption coupled with biodegradation (using fly ash immobilized with Pseudomonas sp.) on a comparative scale. To ascertain immobilization of bacteria on fly ash, immobilized bacterial cells were characterized by energy-dispersive X-ray spectroscopy, scanning electron microscopy, Fourier-transform-infrared spectroscopy, and fluorescence microscopy. Batch studies were conducted for optimization of the process parameters for ensuring maximum dye removal. The optimum pH, temperature, and initial dye concentration for the highest percentage of dye removal were found to be pH 7, 37 degrees C, and 50 mg/L in all the three cases. Under optimized conditions, the highest percentage of dye removal was found to be 89.24, 79.64, and 99.04% for biodegradation, sorption, and integrated approach of sorption and biodegradation, respectively. Finally, phytotoxicity studies carried out with the treated water on Cicer arietinum seeds also carried proved that these processes and the adsorbent did not exert any toxic effects on the seeds. Artificial neural network modeling revealed a close interaction between theoretically predicted and experimentally obtained results and with an error of around 1.1%. Thus, this novel, environmentally sustainable and economically viable technique may be applied for effective removal of crystal violet from industrial wastewater. PMID- 29576999 TI - The effect of chitosan-PMAA-NPK nanofertilizer on Pisum sativum plants. AB - The use of chitosan (CS) as a carrier for slow fertilizer release is a novel trend. The potential effect of this system in agriculture is still debatable. Here, chitosan (CS) nanoparticles were obtained by polymerizing methacrylic acid (PMAA) for the entrapment of nitrogen, phosphorous and potassium (NPK) nanoparticles (NP), each at a time to form CS-PMAA-NPK NPs complex. The impact of this complex was evaluated using garden pea (Pisum sativum var. Master B) plants. Five-day-old pea seedlings were treated through their root system with CS-PMAA NPK NPs at concentrations of 1, 0.5, 0.25, 0.125 and 0.0625 of the stock solution (R) for 1, 2, 4 and 7 days. In general, CS-PMAA-NPK NP complex reduced root elongation rate and resulted in the accumulation of starch at the root tip in a dose-dependent manner within the treated plants. Interestingly, the lowest concentrations of 0.0625 and 0.125 R had induced mitotic cell division (MI = 22.45 +/- 2.68 and 19.72 +/- 3.48, respectively) compared with the control (MI = 9.09 +/- 3.28). In addition, some of major proteins such as convicilin, vicilin and legumin beta were upregulated in plants treated with these low concentrations too. However, all concentrations used exhibited genotoxic effect on DNA based on the comet assay data after 48 h of treatment. Thus, it is highly recommended to consider the negative effects of this carrier system on plants and environment that may arise due to its accumulation in the agricultural fields.

AB - Significant efforts are being directed towards the improvement of rice using genetic manipulations. A good and reproducible system for recovering fertile Indica rice plants is imperative. The aim of this study was to study the influence of initial cell density on growth dynamics of suspension cultures. The cultures were initiated from 3-week-old embryogenic calli derived from mature seeds of Indica rice cultivars ASD16 and Pusa basmati. Growth kinetics of the rice cell suspensions were measured and the obtained data reveal that viable cells at 3% PCV using 20 ml liquid (N6D) medium and sub-culturing at 7-day intervals resulted in rapid increase in fresh and dry weights and the embryogenic competency of the cells were found to be high. The growth kinetics analysis revealed that ASD16 showed better efficiency for high frequency and viable somatic embryo formation as compared to Pusa basmati. The technique was found to be suitable for developing somatic embryos for both cultivars ASD16 and Pusa basmati, which can be used for many important applications including micropropagation and secondary metabolites production.

AB - A 5-year-old girl was referred to our unit with an incidental finding of a lesion on the right hemithorax situated within the right atrial shadow. Computed tomography thorax showed a well-defined soft tissue lesion felt to be consistent with a bronchogenic cyst. The lesion was located in the posterior mediastinum, adherent to the diaphragm and inferior vena cava, but did not extend within the wall of the esophagus. It was entirely excised via video-assisted thoracoscopy converted to open thoracotomy. Histopathology confirmed an encapsulated nodular tissue measuring 2.5 * 2.5 * 2 cm lined by squamous type epithelium. Chronic inflammatory cells and foreign body giant cell reaction were found in the cyst wall. The appearances were that of a benign epidermoid cyst.

AB - Thoracoscopic prosthetic repair of congenital diaphragmatic hernia (CDH) is a well-established and safe technique in experienced hands but the patching procedure is technically demanding and time consuming. To address the challenges associated with this process (confined working space and restricted time), the aim of this article is to assess the potential improvements in feasibility, efficacy, and safety of patch fixation by using nonabsorbable helicoidal tacks in neonates and infants for the repair of large CDH by thoracoscopy. The new technique has all the advantages of minimal invasive surgery in very young children combined with the advantages of reduced operating time and increased simplicity, and may be a good option in cases of recurrence.

AB - A 63-year-old female with a history of kidney transplantation was admitted for emergency repair of a perforated mycotic aneurysm of the right subclavian artery (RSA) in combination with a paravertebral and posterior mediastinal abscess. After resection of the aneurysm and after radical local debridement, orthotopic repair was performed with a self-made pericardial tube graft from the brachiocephalic bifurcation to the thoracic outlet. The paravertebral and posterior mediastinal abscess was drained. The postoperative course was uneventful. Using a self-made readily available pericardial neo-tube enlarges the armamentarium of handling complex infective surgical scenarios and presents a smart alternative to alloplastic vascular reconstruction.

AB - Background Factor X deficiency (also known as Stuart-Prower factor deficiency) is an autosomal recessive extremely rare hereditary hematologic disorder, affecting around 1:1,000,000 of the general population. Case Presentation This case report describes a patient with hypoplastic left heart syndrome and severe factor X deficiency, who underwent staged surgical palliation. From stage 1 Norwood palliation, through superior cavopulmonary anastomosis and ending with total cavopulmonary connection with satisfactory hemostasis and no significant perioperative bleeding complication. Conclusion The need to maintain hemostasis while aiming to prevent intracardiac thrombosis requires multidisciplinary team approach including hematologist, cardiac surgeon, pediatric cardiac intensivist, and anesthesiologist along with meticulous hemostasis during surgery and careful monitoring of coagulation profile in the postoperative period. PMID- 29577005 TI - Transposition of Great Arteries with Left Main Coronary Artery Atresia-Case Report. AB - Background The coronary artery anatomy in patients with transposition of the great artery (TGA) is a contributing factor for outcome in arterial switch procedure. Case Presentation A full-term, 7-day-old baby boy diagnosed as dextro TGA (dTGA) with intact ventricular septum. Intraoperatively, the left coronary sinus had a blind indentation from which a firm cord-like left main coronary artery originates. Procedure completed as usual for a routine arterial switch operation. Conclusion About 5% of patients with D-TGA have a single coronary artery. Assessment of blood flow to all branches intraoperatively is mandatory to choose between either transfer of single ostium or bypass grafting to the other coronary system. PMID- 29577006 TI - Immittance Data Validation using Fast Fourier Transformation (FFT) Computation - Synthetic and Experimental Examples. AB - Exact data of an electric circuit (EC) model of RLC (resistor, inductor, capacitor) elements representing rational immittance of LTI (linear, time invariant) systems are numerically Fourier transformed to demonstrate within error bounds applicability of the Hilbert integral tranform (HT) and Kramers Kronig (KK) integral tranform (KKT) method. Immittance spectroscopy (IS) data are validated for their HT (KKT) compliance using non-equispaced fast Fourier transformation (NFFT) computations. Failing of HT (KKT) testing may not only stem from non-compliance with causality, stability and linearity which are readily distinguished using anti HT (KKT) relations. It could also indicate violation of uniform boundedness to be overcome either by using singly or multiply subtracted KK transform (SSKK or MSKK) or by seeking KKT of the same set of data at a complementary immit- tance level. Experimental IS data of a fuel cell (FC) are also numerically HT (KKT) validated by NFFT assessing whether LTI principles are met. Figures of merit are suggested to measure success in numerical validation of IS data. PMID- 29577007 TI - Immittance Data Validation by Kramers-Kronig Relations - Derivation and Implications. AB - Explicitly based on causality, linearity (superposition) and stability (time invariance) and implicit on continuity (consistency), finiteness (convergence) and uniqueness (single valuedness) in the time domain, Kramers-Kronig (KK) integral transform (KKT) relations for immittances are derived as pure mathematical constructs in the complex frequency domain using the two-sided (bilateral) Laplace integral transform (LT) reduced to the Fourier domain for sufficiently rapid exponential decaying, bounded immittances. Novel anti KK relations are also derived to distinguish LTI (linear, time invariant) systems from non-linear, unstable and acausal systems. All relations can be used to test KK transformability on the LTI principles of linearity, stability and causality of measured and model data by Fourier transform (FT) in immittance spectroscopy (IS). Also, integral transform relations are provided to estimate (conjugate) immittances at zero and infinite frequency particularly useful to normalise data and compare data. Also, important implications for IS are presented and suggestions for consistent data analysis are made which generally apply likewise to complex valued quantities in many fields of engineering and natural sciences. PMID- 29577008 TI - Improved Performance of Ionic Liquid Supercapacitors by using Tetracyanoborate Anions. AB - Supercapacitors are energy storage devices designed to operate at higher power densities than conventional batteries, but their energy density is still too low for many applications. Efforts are made to design new electrolytes with wider electrochemical windows than aqueous or conventional organic electrolytes in order to increase energy density. Ionic liquids (ILs) with wide electrochemical stability windows are excellent candidates to be employed as supercapacitor electrolytes. ILs containing tetracyanoborate anions [B(CN)4] offer wider electrochemical stability than conventional electrolytes and maintain a high ionic conductivity (6.9 mS cm-1). Herein, we report the use of ILs containing the [B(CN)4] anion for such an application. They presented a high maximum operating voltage of 3.7 V, and two-electrode devices demonstrate high specific capacitances even when operating at relatively high rates (ca. 20 F g-1 @ 15 A g 1). This supercapacitor stored more energy and operated at a higher power at all rates studied when compared with cells using a commonly studied ILs. PMID- 29577009 TI - Intrusive Memories of Trauma in the Laboratory: Methodological Developments and Future Directions. AB - Purpose of the Review: Intrusive memories are those that spring to mind unbidden, e.g. sensory recollections of stressful/traumatic events. We review recent methods to monitor intrusions of a stressor (a trauma film) within the laboratory. Recent Findings: Recent studies suggest three main methodologies after viewing a trauma film by which to monitor intrusions in the laboratory: during post-film rest periods, after exposure to trigger cues, and while performing an ongoing task. These approaches allow factors to be tested (e.g. psychological or pharmacological) that may influence the frequency of occurrence of intrusions. Summary: We raise methodological considerations to guide trauma film studies using intrusion monitoring in the laboratory to complement monitoring approaches in daily life (e.g. diaries). Intrusion monitoring in the laboratory also confers greater experimental control and may open novel research avenues, to advance intervention development to mitigate problematic intrusive memory symptoms. PMID- 29577010 TI - Developmental Aspects of Schizotypy and Suspiciousness: a Review. AB - Purpose of the Review: This review identifies the early developmental processes that contribute to schizotypy and suspiciousness in adolescence and adulthood. It includes the most recent literature on these phenomena in childhood. Recent Findings: The early developmental processes that affect schizotypy and paranoia in later life are complex. In contrast to existing studies of psychiatric patients and clinical/nonclinical adult populations, the study of schizotypy and suspiciousness in young children and adolescents is possible due to new child appropriate dimensional assessments. New assessments and the advancement of technology (e.g., virtual reality in mental health) as well as statistical modeling (e.g., mediation and latent-class analyses) in large data have helped identified the developmental aspects (e.g., psychosocial, neurocognitive and brain factors, nutrition, and childhood correlates) that predict schizotypy and suspiciousness in later life. Summary: Prospective longitudinal designs in community youths can enhance our understanding of the etiology of schizophrenia spectrum disorders and, in the future, the development of preventive interventions by extending adult theories and interventions to younger populations. PMID- 29577011 TI - Current Understanding of the Neural Mechanisms of Dissociation in Borderline Personality Disorder. AB - Purpose of Review: In this article, we aim to give an overview over recent neuroimaging research on dissociation in borderline personality disorder (BPD). Stress-related dissociation is highly prevalent in BPD, while so far only little is known about its neural underpinnings. Recent Findings: Based on research in depersonalization and the dissociative subtype of posttraumatic stress disorder, it has been proposed that dissociation involves alterations in a cortico-limbic network. In BPD, neuroimaging research explicitly focusing on dissociation is still scarce. Summary: Functional neuroimaging studies have provided preliminary evidence for an altered recruitment and interplay of fronto-limbic regions (amygdala, anterior cingulate, inferior frontal gyrus, medial and dorsolateral prefrontal cortices) and temporoparietal areas (superior temporal gyrus, inferior parietal lobule, fusiform gyrus), which may underlie disrupted affective cognitive processing during dissociation in BPD. More neuroimaging research with larger samples, clinical control groups, and repeated measurements is needed to deepen the understanding of dissociation in BPD. PMID- 29577012 TI - Strongyloides stercoralis and relatives: recent advances in general and molecular biology. AB - Human strongyloidiasis is a threat to global health, presenting significant challenges in diagnosis and clinical management. The imperative to incorporate strongyoidiasis more fully into control programs for soil-transmitted helminths is increasingly recognized. The unique life cycles of S. stercoralis and congeneric species contain both free-living and parasitic generations, and transcriptomic methods have recently identified genes of potential importance to parasitism in these parasites. Proteomics recently revealed stage-specific secreted proteins that appear crucial to the host-parasite interaction. A comprehensive genome sequencing project for Strongyloides spp. is now nearing completion. Recent technical advances in transgenesis for S. stercoralis and S. ratti, including the first establishment of stable transgenic lines, promise to advance functional evaluations of genes expressed in conjunction with crucial life cycle events. Studies employing these methods recently bolstered the hypothesis that S. stercoralis uses cellular signaling pathways homologous to three that regulate dauer larval development in Caenorhabditis elegans to regulate morphogenesis and development of its infective third-stage larva. The free-living generation of Strongyloides makes classical genetics formally possible. Recent advances, such as a genetic map of S. ratti and a molecular genetic and karyotypic analysis of sex determination in S. papillosus, will greatly facilitate this approach. Advanced methods for study of chemosensation in C. elegans were recently applied to discover numerous host attractant molecules that mediate host finding and contact by infective third-stage larvae of Strongyloides spp. Finally, nucleic acid-based diagnostic methods have recently come to the fore as alternatives to parasitological and immunodiagnostic techniques. PMID- 29577013 TI - Effect of ribbon width on electrical transport properties of graphene nanoribbons. AB - There has been growing interest in developing nanoelectronic devices based on graphene because of its superior electrical properties. In particular, patterning graphene into a nanoribbon can open a bandgap that can be tuned by changing the ribbon width, imparting semiconducting properties. In this study, we report the effect of ribbon width on electrical transport properties of graphene nanoribbons (GNRs). Monolayer graphene sheets and Si nanowires (NWs) were prepared by chemical vapor deposition and a combination of nanosphere lithography and metal assisted electroless etching from a Si wafer, respectively. Back-gated GNR field effect transistors were fabricated on a heavily p-doped Si substrate coated with a 300 nm-thick SiO2 layer, by O2 reactive ion etching of graphene sheets using etch masks based on Si NWs aligned on the graphene between the two electrodes by a dielectrophoresis method. This resulted in GNRs with various widths in a highly controllable manner, where the on/off current ratio was inversely proportional to ribbon width. The field-effect mobility decreased with decreasing GNR widths due to carrier scattering at the GNR edges. These results demonstrate the formation of a bandgap in GNRs due to enhanced carrier confinement in the transverse direction and edge effects when the GNR width is reduced. PMID- 29577014 TI - The impact of violence, perceived stigma, and other work-related stressors on depressive symptoms among women engaged in sex work. AB - While the physical health risks of sex work have been well documented, fewer studies have explored mental health risks associated with sex work. This study examined rates of depressive symptoms and associated risk factors among women engaged in sex work in Mongolia (n=222), a country experiencing significant economic and social development and where mental health infrastructure is in its infancy. A linear regression analysis indicated that significant risk factors for depressive symptoms included paying partner sexual violence, perceived occupational stigma, less social support, and higher harmful alcohol use. As one of the first studies to examine depression among sex workers, this study holds important social welfare implications for this marginalized population in Mongolia and other low-resource settings globally. PMID- 29577015 TI - Multifunctional PEGylated Albumin/IR780/Iron Oxide Nanocomplexes for Cancer Photothermal Therapy and MR Imaging. AB - A multifunctional albumin/superparamagnetic iron oxide nanoparticle (SPIO) nanocomplex system to deliver IR780, a photothermal agent, for cancer theranostic applications was proposed in this study. Single emulsion method was utilized to fabricate the human albumin/IR780/SPIO (HISP) nanocomplexes with a hydrophobic core (SPIO and IR780) and a hydrophilic shell (human serum albumin (HSA) and poly (ethylene glycol) (PEG)). Effects of PEGylation on the size and surface potential of nanocomplexes were analyzed. Nanospheres containing uniformly dispersed SPIO was observed using Transmission Electron Microscopy (TEM) imaging. As a potential magnetic resonance (MR) imaging agent, the HISP displayed dose-dependent T2 weighted imaging contrast (R2 = 81.6 mM-1s-1). Good colloidal stability was verified from the nanocomplexes under difference circumstances. The nanocomplexes were taken up by cancer cells efficiently and led to significant photothermal mediated cancer cell death upon short-term near infrared (NIR) irradiation in vitro. Via intravenous injection, PEG-HISP can efficiently deliver IR780 to tumor sites and showed strong photothermal effect compared to free drug on the mice model. Significant tumor suppression by the photothermal treatments using PEG HISP was demonstrated from the mice CT26 xenograft model. Good safety profile of the PEG-HISP was confirmed from histological examination and liver functional analysis. Taken together, the results suggest that PEG-HISP is a safe and robust nano-theranostic platform for advanced anti-cancer treatment. PMID- 29577016 TI - Iodinated Echogenic Glycol Chitosan Nanoparticles for X-ray CT/US Dual Imaging of Tumor. AB - Development of biopolymer-based imaging agents which can access rapidly and provide detailed information about the diseases has received much attention as an alternative to conventional imaging agents. However, development of biopolymer based nanomaterials for tumor imaging still remains challenging due to their low sensitivity and image resolution. To surmount of these limitations, multimodal imaging agents have been developed, and they were widely utilized for theranostic applications. Herein, iodine containing echogenic glycol chitosan nanoparticles are developed for x-ray computed tomography (CT) and ultrasound (US) imaging of tumor diagnosis. X-ray CT/US dual-modal imaging probe was prepared by following below two steps. First, iodine-contained diatrizoic acid (DTA) was chemically conjugated to the glycol chitosan (GC) for the CT imaging. DTA conjugated GC (GC DTA NPs) formed stable nanoparticles with an average diameter of 315 nm. Second, perfluoropentane (PFP), a US imaging agent, was physically encapsulated into GC DTA NPs by O/W emulsion method yielding GC-DTA-PFP nanoparticles (GC-DTA-PFP NPs). The GC-DTA-PFP NPs formed nanoparticles in physiological condition, and they presented the strong x-ray CT, and US signals in phantom test in vitro. Importantly, GC-DTA-PFP NPs were effectively accumulated on the tumor site by enhanced permeation and retention (EPR) effects. Moreover, GC-DTA-PFP NPs showed x-ray CT, and US signals in tumor tissues after intratumoral and intravenous injection, respectively. Therefore, GC-DTA-PFP NPs indicated that x-ray CT/US dual-modal imaging using iodinated echogenic nanoparticles could be provided more comprehensive and accurate diagnostic information to diagnosis of tumor. PMID- 29577017 TI - High-density human mesenchymal stem cell rings with spatiotemporally-controlled morphogen presentation as building blocks for engineering bone diaphyseal tissue. AB - Emerging biomimetic tissue engineering strategies aim to partially recapitulate fundamental events that transpire during embryonic skeletal development; namely, cellular self-organization and targeted morphogenetic pathway activation. Here, we describe self-assembled, scaffold-free human mesenchymal stem cell (hMSC) rings featuring microparticle-mediated presentation of transforming growth factor beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2). We tested the hypothesis that spatiotemporally-controlled dual presentation of TGF-beta1 and BMP-2 is superior in modulating in vitro endochondral ossification of high density cellular constructs compared to single morphogen delivery. hMSC rings were engineered by seeding cells with microparticles presenting (1) TGF-beta1, (2) BMP-2, or (3) TGF-beta1 + BMP-2 in custom agarose wells to facilitate self assembly within 2 d, followed by horizontal culture on glass tubes for 5 weeks. At day 2, hMSC rings across groups revealed homogenous cellular organization mimetic of early mesenchymal condensation with no evidence of new matrix or mineral deposition. Significant early chondrogenic and osteogenic priming occurred with TGF-beta1 + BMP-2 presentation compared to single morphogen-loaded groups. By week 5, TGF-beta1-loaded hMSC rings had undergone chondrogenesis, while presentation of BMP-2 alone or in conjunction with TGF-beta1 stimulated chondrogenesis, chondrocyte hypertrophy, and osteogenesis indicative of endochondral ossification. Importantly, tissue mineralization was most compelling with TGF-beta1 + BMP-2 loading. Lastly, hMSC ring 'building blocks' were shown to efficiently fuse into tubes within 6 d post self-assembly. The resulting tubular tissue units exhibited structural integrity, highlighting the translational potential of this advanced biomimetic technology for potential early implantation in long bone defects. PMID- 29577018 TI - Ternary Aligned Nanofibers of RGD Peptide-Displaying M13 Bacteriophage/PLGA/Graphene Oxide for Facilitated Myogenesis. AB - Recently, there have been tremendous efforts to develop the biofunctional scaffolds by incorporating various biochemical factors. In the present study, we fabricated poly(lactic-co-glycolic acid) (PLGA) nanofiber sheets decorated with graphene oxide (GO) and RGD peptide. The decoration of GO and RGD peptide was readily achieved by using RGD peptide-displaying M13 bacteriophage (RGD-M13 phage) and electrospinning. Furthermore, the aligned GO-decorated PLGA/RGD peptide (GO-PLGA/RGD) ternary nanofiber sheets were prepared by magnetic field assisted electrospinning, and their potentials as bifunctional scaffolds for facilitating myogenesis were explored. We characterized the physicochemical and mechanical properties of the sheets by scanning electron microscopy, Raman spectroscopy, contact angle measurement, and tensile test. In addition, the C2C12 skeletal myoblasts were cultured on the aligned GO-PLGA/RGD nanofiber sheets, and their cellular behaviors, including initial attachment, proliferation and myogenic differentiation, were evaluated. Our results revealed that the GO PLGA/RGD nanofiber sheets had suitable physicochemical and mechanical properties for supporting cell growth, and could significantly promote the spontaneous myogenic differentiation of C2C12 skeletal myoblasts. Moreover, it was revealed that the myogenic differentiation was further accelerated on the aligned GO PLGA/RGD nanofiber sheets due to the synergistic effects of RGD peptide, GO and aligned nanofiber structure. Therefore, , it is suggested that the aligned GO PLGA/RGD ternary nanofiber sheets are one of the most promising approaches for facilitating myogenesis and promoting skeletal tissue regeneration. PMID- 29577019 TI - Fabrication of Positively Charged Fluorescent Polymer Nanoparticles for Cell Imaging and Gene Delivery. AB - Development of efficient non-viral gene delivery vector has aroused great attention in the past few decades. In this study, we reported a new gene delivery vector, positively charged fluorescent conjugated polymer nanoparticles (CPNPs), for efficient gene transfection and in-situ intracellular fluorescence imaging. The microscopic and spectroscopic characterizations demonstrated that these CPNPs possess decent fluorescence performance (e.g. with fluorescence quantum yield of 70.7+/-0.3%) and small size dimension of ~3.6+/-0.3 nm (DLS result). Fast and efficient cellular translocation capability was observed according to the time dependent living cell imaging experiments. Nearly all of the cells were loaded with CPNPs after co-incubation for 2 h regardless of the cell type. In comparison with the commonly used gene delivery vector, lipofectamine 2000 (with gene transfection efficiency of 55+/-5% for pEGFP), the gene expression efficiency with the positively charged CPNPs (70+/-3% for pEGFP) was improved significantly. Intracellular fluorescence imaging results demonstrated that the CPNPs could actively assemble close to the periphery of nuclei. Disassembly was not observed even 36 h later, which greatly facilitates releasing of pDNA close to the periphery of nuclei and thus promotes the gene transfection efficiency. PMID- 29577020 TI - Functionalised Carbon Nanotubes Enhance Brain Delivery of Amyloid-Targeting Pittsburgh Compound B (PiB)-Derived Ligands. AB - Alzheimer's disease (AD) is a neurodegenerative disorder characterised by brain accumulation of toxic protein aggregates, including extracellular amyloid beta (Abeta) plaques, inflammation, neuronal death and progressive cognitive dysfunction. Current diagnostic modalities, based on cognitive tests, fail to detect early AD onset, thus emphasising the need to develop improved methods for pre-symptomatic disease detection. Building on the properties of the Pittsburgh Compound B (PiB), an Abeta-binding molecule suitable to use as positron emission tomography (PET) imaging agent, and aiming at using a more clinically available modality (like magnetic ressonance imaging, MRI), PiB derivatives have been conjugated to the macrocyclic chelator 1,4,7-tris(carboxymethyl)-1,4,7,10 tetraazacyclododecane (DO3A) monoamide. However, these derivatives do not readily cross the highly selective blood-brain barrier (BBB). Taking advantage of the capacity of functionalised carbon nanotubes (f-CNTs) to cross biological barriers, including the BBB, this manuscript reports on the conjugation of two PiB derivative Gd3+ complexes - Gd(L2) and Gd(L3) - to multi-walled f-CNTs (f MWNTs) and assessment of their in vivo biodistribution and brain uptake. It is shown that Gd(L2) and Gd(L3) can be efficiently loaded onto different f-MWNTs, with significant improvement in brain accumulation of the conjugates compared to the free metal complexes. Overall, this study demonstrates that f-MWNTs have potential to be used as carriers in theranostic applications involving brain delivery of BBB impermeable compounds. PMID- 29577022 TI - Writing a review article - Are you making these mistakes? AB - An explosion of scientific publications over the last decades has increased the need for review articles: Carefully crafted scientific review articles can provide the novice reader with an overview of a new subject and provide the expert with a synthesis of scientific evidence, proof of reproducibility of published data and pooled estimates of common truth through meta-analyses. Unfortunately, while there are ample presentations and published guidelines for the preparation of scientific articles available, detailed information about how to properly prepare scientific review articles is relatively scarce. This perspective summarizes possible mistakes that can lead to misinformation in scientific review articles with the goal to help authors to improve the scientific contribution of their review article and thereby, increase the respective value of these articles for the scientific community. PMID- 29577021 TI - Penicillin Detection by Tobacco Mosaic Virus-Assisted Colorimetric Biosensors. AB - The presentation of enzymes on viral scaffolds has beneficial effects such as an increased enzyme loading and a prolonged reusability in comparison to conventional immobilization platforms. Here, we used modified tobacco mosaic virus (TMV) nanorods as enzyme carriers in penicillin G detection for the first time. Penicillinase enzymes were conjugated with streptavidin and coupled to TMV rods by use of a bifunctional biotin-linker. Penicillinase-decorated TMV particles were characterized extensively in halochromic dye-based biosensing. Acidometric analyte detection was performed with bromcresol purple as pH indicator and spectrophotometry. The TMV-assisted sensors exhibited increased enzyme loading and strongly improved reusability, and higher analysis rates compared to layouts without viral adapters. They extended the half-life of the sensors from 4 - 6 days to 5 weeks and thus allowed an at least 8-fold longer use of the sensors. Using a commercial budget-priced penicillinase preparation, a detection limit of 100 uM penicillin was obtained. Initial experiments also indicate that the system may be transferred to label-free detection layouts. PMID- 29577023 TI - Geostatistical estimation and prediction for censored responses. AB - Spatially-referenced geostatistical responses that are collected in environmental sciences research are often subject to detection limits, where the measures are not fully quantifiable. This leads to censoring (left, right, interval, etc), and various ad hoc statistical methods (such as choosing arbitrary detection limits, or data augmentation) are routinely employed during subsequent statistical analysis for inference and prediction. However, inference may be imprecise and sensitive to the assumptions and approximations involved in those arbitrary choices. To circumvent this, we propose an exact maximum likelihood estimation framework of the fixed effects and variance components and related prediction via a novel application of the Stochastic Approximation of the Expectation Maximization (SAEM) algorithm, allowing for easy and elegant estimation of model parameters under censoring. Both simulation studies and application to a real dataset on arsenic concentration collected by the Michigan Department of Environmental Quality demonstrate the advantages of our method over the available naive techniques in terms of finite sample properties of the estimates, prediction, and robustness. The proposed methods can be implemented using the R package CensSpatial. PMID- 29577024 TI - Healthcare-resource utilization associated with radiation to bone across eight European countries: Results from a retrospective study. AB - Background: Bone metastases and lytic lesions due to multiple myeloma are common in advanced cancer and can lead to debilitating complications (skeletal-related events [SREs]), including requirement for radiation to bone. Despite the high frequency of radiation to bone in patients with metastatic bone disease, our knowledge of associated healthcare resource utilization (HRU) is limited. Methods: This retrospective study estimated HRU following radiation to bone in Austria, the Czech Republic, Finland, Greece, Poland, Portugal, Sweden and Switzerland. Eligible patients were >= 20 years old, had bone metastases secondary to breast, lung or prostate cancer, or bone lesions associated with multiple myeloma, and had received radiation to bone between 1 July 2004 and 1 July 2009. HRU data were extracted from hospital patient charts from 3.5 months before the index SRE (radiation to bone preceded by a SRE-free period of >= 6.5 months) until 3 months after the last SRE that the patient experienced during the study period. Results: In total, 482 patients were included. The number of inpatient stays increased from baseline by a mean of 0.52 (standard deviation [SD] 1.17) stays per radiation to bone event and the duration of stays increased by a mean of 7.8 (SD 14.8) days. Outpatient visits increased by a mean of 4.24 (SD 6.57) visits and procedures by a mean of 8.51 (SD 7.46) procedures. Conclusion: HRU increased following radiation to bone across all countries studied. Agents that prevent severe pain and delay the need for radiation have the potential to reduce the burden imposed on healthcare resources and patients. PMID- 29577025 TI - A simulations approach for meta-analysis of genetic association studies based on additive genetic model. AB - Meta-analysis of genetic association studies is being increasingly used to assess phenotypic differences between genotype groups. When the underlying genetic model is assumed to be dominant or recessive, assessing the phenotype differences based on summary statistics, reported for individual studies in a meta-analysis, is a valid strategy. However, when the genetic model is additive, a similar strategy based on summary statistics will lead to biased results. This fact about the additive model is one of the things that we establish in this paper, using simulations. The main goal of this paper is to present an alternate strategy for the additive model based on simulating data for the individual studies. We show that the alternate strategy is far superior to the strategy based on summary statistics. PMID- 29577026 TI - Consensus on Pegylated Interferon Alpha in Treatment of Chronic Hepatitis B. PMID- 29577027 TI - Upgrade Combination Response Is Limited by Prolonged Nucelos(t)ide Analogue Therapy in HBeAg-positive Chronic Hepatitis B: A Real-life Study. AB - Background and Aims: Few previous studies have reported on a combination response (hepatitis B virus (HBV) DNA undetected, alanine aminotransferase normalization and hepatitis B e antigen (HBeAg) seroconversion) following nucleos(t)ide analogue (NAs) long-term therapy in patients with chronic hepatitis B (CHB). This study aimed to investigate the combination response on long-term NAs therapy in patients with HBeAg-positive CHB and to determine whether prolonged therapy is beneficial for combination response, particularly in optimal patients (baseline alanine aminotransferase level >=5 upper limit of normal and HBV DNA level <109 copies/mL). Methods: In total, 280 HBeAg-positive CHB patients were enrolled in this study. Among them, 190 were treated with entecavir and 90 were treated with telbivudine. Results: The cumulative rates of combination response in the total number of patients were 8.6% at 1 year, 13.2% at 2 years, 19.1% at 3 years, 24.2% at 4 years and 26.0% at 5 years. In optimal patients, the cumulative rate of combination response was significantly higher than that in the non-optimal patients at 3 years (p = 0.043); the trend of the cumulative rate was not strong at the later time. Interestingly, in optimal patients, combination response mainly occurred in the first 3 years. Multivariate analysis identified HBeAg/anti HBe seroconversion at 1 year as the only factor for combination response in optimal patients (hazard ratio: 16.321; p = 0.000). During the 3 years, the proportion with aspartate aminotransaminase to platelet ratio index <=0.5 increased from 15.6% at baseline to 71.3% at year 3. Conclusions: Upgrading the rate of combination response is limited by prolonging the treatment duration of NAs from 3 years to 5 years in HBeAg-positive CHB patients; a new switch treatment strategy modification should be considered, particularly in optimal patients. PMID- 29577028 TI - Sustained Responses in Chronic Hepatitis B Patients with Nucleos(t)ide Analogue Drug-resistance after Peg-interferon Alfa-2a Add-on Treatment: A Long-term Cohort Study. AB - Background and Aims: The use of additional nucleos(t)ide analogues (NAs) without cross-resistance to previously used NAs as a rescue therapy is recommended by most international guidelines for chronic hepatitis B patients with NA resistance. We aimed to investigate the efficacy and safety of combination therapy of peg-interferon (PegIFN) alfa-2a and NA in these patients, comparing to those who switch to an alternative NA therapy without cross-resistance. Methods: In this prospective, comparative and cohort study, data were collected from the patients' hospital records. Eligible patients were those with hepatitis B e antigen (HBeAg) positivity and resistance to one or more NAs. All patients were treated with alternative NA alone or in combination with PegIFN alfa-2a for 52 weeks or 72 weeks, respectively. HBeAg seroconversion was measured at the end of follow-up (EOF; more than 104 weeks after the end of treatment). Results: Sixty three patients were recruited to the cohort study (NA-therapy group = 31 patients; combination therapy group of NA and PegIFN alfa-2a = 32 patients). At the EOF, significantly more patients in the combination therapy group (13/27, 48.2%) achieved primary outcome of HBeAg seroconversion than those in the NA therapy group (4/32, 12.5%) (p = 0.003). Four patients (14.8%) in the combination therapy group achieved hepatitis B surface antigen (HBsAg) loss and HBsAg seroconversion, but none in the NA therapy group did (p = 0.039). In the combination therapy group, 16 patients (51.6%) achieved HBeAg seroconversion at the end of treatment, of which, 11 patients (68.8%) maintained the response until EOF. Conclusions: Adding on PegIFN alfa-2a in combination with NA therapy might be an appropriate rescue treatment option for patients who have prior NA resistance. In addition, combination therapy induced sustained off-treatment biochemical responses in these patients.

AB - Background and Aims: Acute calculous cholecystitis with impending gall bladder perforation in severe liver diseases including decompensated cirrhosis and acute on-chronic liver failure (ACLF) is difficult to manage, due to the procedures such as cholecystectomy and per cutaneous cholecystostomy being associated with high risk and complications in these patients. Methods: Four cases of severe liver disease with acute calculous cholecystitis who presented to the Institute of Liver and Biliary Sciences (New Delhi, India) for further management were included in the study if they underwent endoscopic ultrasound-guided gall bladder drainage (EUS-GBD). The patients were followed up for a minimum of 3 months and outcomes were recorded. Results: Four cases of severe liver disease (three ACLF and one decompensated cirrhosis), with model for end-stage liver disease scores of 24, 26, 23 and 25 respectively, presented with acute calculous cholecystitis (Tokyo grade III) and systemic sepsis (high total leukocyte counts). Their international normalized ratios were 2.3, 2.6, 2.2 and 2.9 respectively, and two were in shock, requiring inotropes at presentation. Ultrasonography of the abdomen confirmed hugely distended gall bladder with stone impacted at the neck and moderate ascites. All these cases underwent EUS-GBD by linear echo endoscope, and had the gastric wall punctured in the antrum using a 19G access needle followed by dilatation of the tract using controlled radial expansion balloon and Sohendra dilator. In three cases, the plastic stents were placed. In the fourth case, a Nagi stent was placed. All the patients recovered and were discharged within a week. Conclusions: EUS-GBD is challenging in severe liver disease but represents a life-saving procedure, and hence can be attempted in such critically ill patients with utmost care and precaution.

AB - Background and Aims: Hepatitis B surface antigen (HBsAg) loss is seldom achieved with nucleos(t)ide analog (NA) therapy in chronic hepatitis B patients but may be enhanced by switching to finite pegylated-interferon (Peg-IFN) alfa-2a. We assessed HBsAg loss with 48- and 96-week Peg-IFN alfa-2a in chronic hepatitis B patients with partial response to a previous NA. Methods: Hepatitis B e antigen (HBeAg)-positive patients who achieved HBeAg loss and hepatitis B virus DNA <200 IU/mL with previous adefovir, lamivudine or entecavir treatment were randomized 1:1 to receive Peg-IFN alfa-2a for 48 (n = 153) or 96 weeks (n = 150). The primary endpoint of this study was HBsAg loss at end of treatment. The ClinicalTrials.gov identifier is NCT01464281. Results: At the end of 48 and 96 weeks' treatment, 14.4% (22/153) and 20.7% (31/150) of patients, respectively, who switched from NA to Peg-IFN alfa-2a cleared HBsAg. Rates were similar irrespective of prior NA or baseline HBeAg seroconversion. Among those who cleared HBsAg by the end of 48 and 96 weeks' treatment, 77.8% (14/18) and 71.4% (20/28), respectively, sustained HBsAg loss for a further 48 weeks. Baseline HBsAg <1500 IU/mL and week 24 HBsAg <200 IU/mL were associated with the highest rates of HBsAg loss at the end of both 48- and 96-week treatment (51.4% and 58.7%, respectively). Importantly, extending treatment from 48 to 96 weeks enabled 48.3% (14/29) more patients to achieve HBsAg loss. Conclusions: Patients on long-term NA who are unlikely to meet therapeutic goals can achieve high rates of HBsAg loss by switching to Peg-IFN alfa-2a. HBsAg loss rates may be improved for some patients by extending treatment from 48 to 96 weeks, although the differences in our study cohort were not statistically significant. Baseline and on-treatment HBsAg may predict HBsAg loss with Peg-IFN alfa-2a. PMID- 29577031 TI - Hepatitis E: Still Waters Run Deep. AB - Hepatitis E is an infectious inflammatory disease of the liver caused by the hepatitis E virus (HEV), a single-stranded RNA virus. Today, it is estimated that there are more than 20 million HEV infections every year, leading to 3.3 million symptomatic cases and more than 56,000 deaths. For a long time it was believed that HEV was a travel-associated disease, endemic in developing countries with poor hygienic standards and unsafe water supply. However, over the past years, publications have demonstrated that autochthonous HEV infections in industrialized countries are far more common than previously thought. Awareness for HEV amongst health care practitioners in industrialized countries is still limited. This relatively rare disease is of great importance, especially in immunocompromised patients where it can cause chronic liver disease. This article comprehensively reviews current literature to give an overview on clinically important topics. It will focus on epidemiological aspects, acute and chronic HEV infection as well as extra-hepatic manifestations, diagnostic approach and treatment options. Furthermore, the article is concluded with a brief outlook on perspectives and urgent problems to be addressed in the future. PMID- 29577032 TI - Autoimmune Hepatitis in the Asia-Pacific Area. AB - Autoimmune hepatitis has been considered as a relatively rare immunological liver disease, especially in the Asia-Pacific area. Although the diagnosis criteria and immunosuppressive treatment regimens have been established, there are still some challenges. According to the different presentations, the personalized management of patients who suffer from this disease, including those with chronic or acute severe onset, the autoantibody-negative phenotype and cirrhosis are necessarily descriptive. Each subgroup of patients should receive an individualized therapy. Here, we review the recent studies of autoimmune hepatitis, mainly focusing on the epidemiology and genetics, personalized diagnostics, individualized treatment strategies, special subgroups and outcomes. Most of the research in the literature is based on Japanese and Chinese populations. PMID- 29577034 TI - Activation of Anti-tumor Immune Response by Ablation of HCC with Nanosecond Pulsed Electric Field. AB - Locoregional therapy is playing an increasingly important role in the non surgical management of hepatocellular carcinoma (HCC). The novel technique of non thermal electric ablation by nanosecond pulsed electric field has been recognized as a potential locoregional methodology for indicated HCC. This manuscript explores the most recent studies to indicate its unique anti-tumor immune response. The possible immune mechanism, termed as nano-pulse stimulation, was also analyzed. PMID- 29577033 TI - Traditional Chinese Medicine and Herb-induced Liver Injury: Comparison with Drug induced Liver Injury. AB - Cases of suspected herb-induced liver injury (HILI) caused by herbal Traditional Chinese Medicines (TCMs) and of drug-induced liver injury (DILI) are commonly published in the scientific literature worldwide. As opposed to the multiplicity of botanical chemicals in herbal TCM products, which are often mixtures of several herbs, conventional Western drugs contain only a single synthetic chemical. It is therefore of interest to study how HILI by TCM and DILI compare with each other, and to what extent results from each liver injury type can be transferred to the other. China is among the few countries with a large population using synthetic Western drugs as well as herbal TCM. Therefore, China is well suited to studies of liver injury comparing drugs with TCM herbs. Despite some concordance, recent analyses of liver injury cases with verified causality, using the Roussel Uclaf Causality Assessment Method, revealed major differences in HILI caused by TCMs as compared to DILI with respect to the following features: HILI cases are less frequently observed as compared to DILI, have a smaller proportion of females and less unintentional rechallenge events, and present a higher rate of hepatocellular injury features. Since many results were obtained among Chinese residents who had access to and had used Western drugs and TCM herbs, such ethnic homogeneity supports the contention that the observed differences of HILI and DILI in the assessed population are well founded. PMID- 29577035 TI - Alcoholic Hepatitis: Lost in Translation. AB - Alcoholic hepatitis is the most severe and acute form of alcoholic liver disease. The mortality rate associated with alcoholic hepatitis is high, largely due to the lack of suitable pharmacological interventions. While there has been substantial research in the area, generating pharmacological interventions has been plagued by the lack of a robust mouse model both for testing and for understanding the underlying pathology. A number of major notable advances have been made in this area recently, with the goal of generating a mouse model of alcoholic hepatitis. The purpose of this article is to review recent advances in modeling alcoholic liver disease both in vitro and in vivo in the mouse, and place them in the context of the greater spectrum of alcoholic liver disease, with a focus on how we can translate current advances into a high-fidelity model of alcoholic hepatitis. In addition, we will review the basic mechanisms of alcoholic hepatitis as it is currently understood, focusing on recent advancements in diagnosis, prognosis and current pathophysiology, especially as it relates to the profound immune dysfunction present during alcoholic hepatitis. PMID- 29577036 TI - Update on Liver Failure Following Hepatic Resection: Strategies for Prediction and Avoidance of Post-operative Liver Insufficiency. AB - Liver resection is increasingly used for a variety of benign and malignant conditions. Despite advances in preoperative selection, surgical technique and perioperative management, posthepatectomy liver failure (PHLF) is still a leading cause of morbidity and mortality following liver resection. Given the devastating physiological consequences of PHLF and the lack of effective treatment options, identifying risk factors and preventative strategies for PHLF is paramount. In the past, a major limitation to conducting high quality research on risk factors and prevention strategies for PHLF has been the absence of a standardized definition. In this article, we describe relevant definitions for PHLF, discuss risk factors and prediction models, and review advances in liver assessment tools and PHLF prevention strategies. PMID- 29577037 TI - Chylous Ascites: A Review of Pathogenesis, Diagnosis and Treatment. AB - Chylous ascites (CA) is a rare form of ascites that results from the leakage of lipid-rich lymph into the peritoneal cavity. This usually occurs due to trauma and rupture of the lymphatics or increased peritoneal lymphatic pressure secondary to obstruction. The underlying etiologies for CA have been classified as traumatic, congenital, infectious, neoplastic, postoperative, cirrhotic or cardiogenic. Since malignancy and cirrhosis account for about two-thirds of all the cases of CA in Western countries, in this article we have attempted to reclassify CA based on portal and non-portal etiologies. The diagnosis of CA is based on the distinct characteristic of the ascitic fluid which includes a milky appearance and a triglyceride level of >200 mg/dL. The management consists of identifying and treating the underlying disease process, dietary modification, and diuretics. Some studies have also supported the use of agents such as orlistat, somatostatin, octreotide and etilefrine. Paracentesis and surgical interventions in the form of transjugular intrahepatic portosystemic shunt (commonly known as TIPS), peritoneal shunt, angiography with embolization of a leaking vessel, and laparotomy remain as treatment options for cases refractory to medical management. PMID- 29577038 TI - Searching for Bacterial Biofilm in Recurrent Cholangitis in Primary Sclerosing Cholangitis: A Case Presentation and Introduction of an Unexplored Disease Mechanism. AB - Inflammation and fibrosis of the bile ducts are the defining pathological characteristics of primary sclerosing cholangitis (PSC). A previously unexplored mechanism for recurrent cholangitis, one of PSC's most common presentations, is bacterial colonization of the biliary epithelium in the form of biofilm, which may confer resistance to antibiotics and host phagocytic machinery. The aim of the current study was to assess whether bacteria could be seen on the liver explant and whether they organized in the form of biofilm. An explanted PSC liver from a 60-year-old male who suffered from recurrent cholangitis was formalin fixed, paraffin-embedded and Gram stained. The specimens were observed under light microscopy. Neither bacteria nor biofilm were detected. We did not detect bacteria or biofilm in the liver explant of a single PSC patient with recurrent cholangitis using standard light microscopy. We suspect this may be in part due to techniques related to tissue preservation and microscopy. PMID- 29577039 TI - Let research leave you breathless, not physical exercise!

PMID- 29577042 TI - Physicians' perspectives on communication and decision making in clinical encounters for treatment of latent tuberculosis infection. AB - The aim of the study was to explore the views of tuberculosis (TB) physicians on treatment of latent TB infection (LTBI), focusing on decision making and communication in clinical practice. 20 Australian TB physicians participated in a semistructured interview in person or over the telephone. Interviews were recorded, transcribed and analysed thematically. The study identified challenges that physicians face when discussing treatment for LTBI with patients. These included difficulties explaining the concept of latency (in particular to patients from culturally and linguistically diverse backgrounds) and providing guidance to patients while still framing treatment decisions as a choice. Tailored estimates of the risk of developing TB and the risk of developing an adverse effect from LTBI treatment were considered the most important information for decision making and discussion with patients. Physicians acknowledged that there is a significant amount of unwarranted treatment variation, which they attributed to the lack of evidence about the risk-benefit balance of LTBI treatment in certain scenarios and guidelines that refer to the need for case-by case decision making in many instances. In order to successfully implement LTBI treatment at a clinical level, consideration should be given to research on how to best address communication challenges arising in clinical encounters. PMID- 29577043 TI - Multidimensional fatigue in pulmonary hypertension: prevalence, severity and predictors. AB - Pulmonary hypertension is a potentially fatal disease. Despite pharmacological advances in pulmonary hypertension, fatigue remains common in patients with pulmonary hypertension. A convenience sample of 120 participants at an international patient conference completed the Multidimensional Fatigue Inventory (MFI)-20 scale. Data on New York Heart Association Functional Class, body mass index, oxygen use and medication type/use were also collected. There was a high prevalence of "severe" to "very severe" fatigue for each dimension: General Fatigue (60%), Physical Fatigue (55.8%), Reduced Activity (41.7%), Reduced Motivation (32.5%) and Mental Fatigue (27.5%). The mean+/-sd overall MFI-20 score was 58+/-5.1. Dimensions with the highest averaged levels were General Fatigue (13.40+/-3.61), Physical Fatigue (13.23+/-3.67) and Reduced Activity (11.33+/ 4.16). Body mass index correlated with higher fatigue scores. Phosphodiesterase inhibitor plus endothelin receptor antagonist combination negatively predicted General Fatigue, Physical Fatigue, Reduced Motivation and Reduced Activity. Triple therapy was a significant predictor of General Fatigue, Physical Fatigue and Reduced Activity. There were no significant predictors of Mental Fatigue. Multidimensional fatigue is common and severe in patients with pulmonary hypertension. Phosphodiesterase inhibitor plus endothelin receptor antagonist combination resulted in lower scores in most fatigue dimensions. Comprehensive assessment of fatigue should be considered in the clinical care of patients with pulmonary hypertension and clinical research to develop formal interventions that target this disabling symptom. PMID- 29577044 TI - Tubulointerstitial Biomarkers for Diabetic Nephropathy. AB - Patients with diabetic nephropathy have a higher risk of mortality, mostly from cardiovascular complications. Standard biomarkers including serum creatinine, estimated glomerular filtration rate, and albuminuria are imprecise, do not directly measure renal tissue injury, and are relatively insensitive to small changes in renal function. Thus, availability of novel biomarkers that are sensitive, specific, and precise as well as able to detect kidney injury and predict clinically significant outcomes would be widely useful in diabetic nephropathy. Novel biomarkers of the processes that induce tubulointerstitial changes may ultimately prove to better predict renal progression and prognosis in type 2 diabetes. Recently, certain biomarkers, which were initially identified in acute kidney injury, also have been reported to confer value in evaluating patients with chronic kidney disease. Biomarkers such as cystatin C, kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), angiotensinogen, periostin, and monocyte chemoattractant protein-1 (MCP-1) reflect tubular injury. In this article, we focused on the potential applications of these biomarkers in diabetic nephropathy. PMID- 29577045 TI - Pycnogenol(r) Induces Browning of White Adipose Tissue through the PKA Signaling Pathway in Apolipoprotein E-Deficient Mice. AB - Beige adipocytes in white adipose tissue (WAT) have received considerable recognition because of their potential protective effect against obesity. Pycnogenol (PYC), extracted from French maritime pine bark, has anti-inflammatory and antioxidant properties and can improve lipid profiles. However, the effect of PYC on obesity has never been explored. In this study, we investigated the effects of PYC on obesity and WAT browning in apolipoprotein E- (ApoE-) deficient mice. The results showed that PYC treatment clearly reversed body weight and the mass of eWAT gain resulting from a high-cholesterol and high-fat diet (HCD), but no difference in food intake. The morphology results showed that the size of the adipocytes in the PYC-treated mice was obviously smaller than that in the HCD-fed mice. Next, we found that PYC upregulated the expression of genes related to lipolysis (ATGL and HSL), while it decreased the mRNA level of PLIN1. PYC significantly increased the expression of UCP1 and other genes related to beige adipogenesis. Additionally, PYC increased the expression of proteins related to the protein kinase A (PKA) signaling pathway. The findings suggested that PYC decreased obesity by promoting lipolysis and WAT browning. Thus, PYC may be a novel therapeutic target for obesity. PMID- 29577046 TI - Beneficial Effects of Human Mesenchymal Stromal Cells on Porcine Hepatocyte Viability and Albumin Secretion. AB - Porcine hepatocytes transplanted during acute liver failure might support metabolic functions until the diseased liver recovers its function. Here, we isolated high numbers of viable pig hepatocytes and evaluated hepatocyte functionality after encapsulation. We further investigated whether coculture and coencapsulation of hepatocytes with human multipotent mesenchymal stromal cells (MSC) are beneficial on hepatocyte function. Livers from 10 kg pigs (n = 9) were harvested, and hepatocytes were isolated from liver suspensions for microencapsulation using alginate and poly(ethylene-glycol)- (PEG-) grafted alginate hydrogels, either alone or in combination with MSC. Viability, albumin secretion, and diazepam catabolism of hepatocytes were measured for one week. 9.2 +/- 3.6 * 109 hepatocytes with 95.2 +/- 3.1% viability were obtained after isolation. At day 3, free hepatocytes displayed 99% viability, whereas microencapsulation in alginate and PEG-grafted alginate decreased viability to 62% and 48%, respectively. Albumin secretion and diazepam catabolism occurred in free and microencapsulated hepatocytes. Coencapsulation of hepatocytes with MSC significantly improved viability and albumin secretion at days 4 and 8 (p < 0.05). Coculture with MSC significantly increased and prolonged albumin secretion. In conclusion, we established a protocol for isolation and microencapsulation of high numbers of viable pig hepatocytes and demonstrated that the presence of MSC is beneficial for the viability and function of porcine hepatocytes. PMID- 29577047 TI - How Hippo Signaling Pathway Modulates Cardiovascular Development and Diseases. AB - Cardiovascular disease remains the leading cause of death around the globe. Cardiac deterioration is associated with irreversible cardiomyocyte loss. Understanding how the cardiovascular system develops and the pathological processes of cardiac disease will contribute to finding novel and preventive therapeutic methods. The canonical Hippo tumor suppressor pathway in mammalian cells is primarily composed of the MST1/2-SAV1-LATS1/2-MOB1-YAP/TAZ cascade. Continuing research on this pathway has identified other factors like RASSF1A, Nf2, MAP4Ks, and NDR1/2, further enriching our knowledge of the Hippo-YAP pathway. YAP, the core effecter of the Hippo pathway, may accumulate in the nucleus and initiate transcriptional activity if the pathway is inhibited. The role of Hippo signaling has been widely investigated in organ development and cancers. A heart of normal size and function which is critical for survival could not be generated without the proper regulation of the Hippo tumor suppressor pathway. Recent research has demonstrated a novel role of Hippo signaling in cardiovascular disease in the context of development, hypertrophy, angiogenesis, regeneration, apoptosis, and autophagy. In this review, we summarize the current knowledge of how Hippo signaling modulates pathological processes in cardiovascular disease and discuss potential molecular therapeutic targets. PMID- 29577048 TI - Leaf-Encapsulated Vaccines: Agroinfiltration and Transient Expression of the Antigen Staphylococcal Endotoxin B in Radish Leaves. AB - Transgene introgression is a major concern associated with transgenic plant-based vaccines. Agroinfiltration can be used to selectively transform nonreproductive organs and avoid introgression. Here, we introduce a new vaccine modality in which Staphylococcal enterotoxin B (SEB) genes are agroinfiltrated into radishes (Raphanw sativus L.), resulting in transient expression and accumulation of SEB in planta. This approach can simultaneously express multiple antigens in a single leaf. Furthermore, the potential of high-throughput vaccine production was demonstrated by simultaneously agroinfiltrating multiple radish leaves using a multichannel pipette. The expression of SEB was detectable in two leaf cell types (epidermal and guard cells) in agroinfiltrated leaves. ICR mice intranasally immunized with homogenized leaves agroinfiltrated with SEB elicited detectable antibody to SEB and displayed protection against SEB-induced interferon-gamma (IFN-gamma) production. The concept of encapsulating antigens in leaves rather than purifying them for immunization may facilitate rapid vaccine production during an epidemic disease. PMID- 29577049 TI - The Influence of Genetic Variations in the CD86 Gene on the Outcome after Allogeneic Hematopoietic Stem Cell Transplantation. AB - CD86 molecule is the ligand for both costimulatory (CD28) and coinhibitory (CTLA 4) molecules, and it regulates immune response after allogeneic hematopoietic stem cell transplantation (alloHSCT). Therefore, we postulate that CD86 gene variations might influence the outcome after alloHSCT. Altogether, 295 adult patients (pts) undergoing related (105 pts) and unrelated (190 pts) donor-matched HSCT were genotyped for the following CD86 gene polymorphisms: rs1129055, rs9831894, and rs2715267. Moreover, the donors' rs1129055 polymorphism was determined. None of the investigated SNPs alone were associated with aGvHD and rate of relapse. However, we showed that rs2715267 SNP influenced overall survival (OS) after alloHSCT. The 24-month OS for the rs271526GG recipients was worse than that for the recipients possessing T allelle (TT or GT genotypes) (p = 0.009). Moreover, analysis of gene-gene interaction between CD86 and CTLA-4 showed that having both the A allele for CD86 rs1129055 and the CTLA-4 CT60GG genotype in recipients increased the risk of aGvHD about 3.5 times. Interestingly, the donors' rs1129055GG genotype and the recipients' CT60GG genotype also increased the risk of aGvHD about 2.7-fold. We postulate that recipients' CD86 gene polymorphisms influence the overall survival after alloHSCT and, together with CTLA-4 polymorphisms, might be considered a risk factor for aGvHD. PMID- 29577050 TI - Anticancer Drugs Induced Severe Adverse Cutaneous Drug Reactions: An Updated Review on the Risks Associated with Anticancer Targeted Therapy or Immunotherapies. AB - Cutaneous adverse drug reactions are commonly seen in patients with anticancer drug treatment. Anticancer drugs, including chemotherapy, target therapy, and recent immunotherapy causing skin reactions ranging from mild skin rash to life threatening severe cutaneous adverse reactions (SCARs), such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrosis (TEN) with increase morbidity and mortality while they are receiving cancer treatments, have been proposed to be a result of direct skin toxicity or drug hypersensitivity reactions (these are proposed mechanism, not definite). Differentiating SCARs from other more commonly seen reactions with a better outcome help prevent discontinuation of therapy and inappropriate use of systemic immunosuppressants for presumable allergic reactions, of which will affect the clinical outcome. In this article, we have reviewed published articles from 1950 to August 2017 for SJS/TEN associated with anticancer drugs, including chemotherapy, targeted therapy, and immunotherapy. We aimed to provide an overview of SJS/TEN associated with anticancer drugs to increase clinician recognition and accelerate future studies on the pathomechanism and managements. PMID- 29577051 TI - Aspergillus fumigatus Infection-Induced Neutrophil Recruitment and Location in the Conducting Airway of Immunocompetent, Neutropenic, and Immunosuppressed Mice. AB - Susceptibility to fungal infection is commonly associated with impaired neutrophil responses. To study the mechanisms underlying this association, we investigated neutrophil recruitment to the conducting airway wall after Aspergillus fumigatus conidium inhalation in mouse models of drug-induced immunosuppression and antibody-mediated neutrophil depletion (neutropenia) by performing three-dimensional confocal laser-scanning microscopy of whole-mount primary bronchus specimens. Actin staining enabled visualization of the epithelial and smooth muscle layers that mark the airway wall. Gr-1+ or Ly6G+ neutrophils located between the epithelium and smooth muscles were considered airway wall neutrophils. The number of airway wall neutrophils for immunocompetent, immunosuppressed, and neutropenic mice before and 6 h after A. fumigatus infection were analyzed and compared. Our results show that the number of conducting airway wall neutrophils in immunocompetent mice significantly increased upon inflammation, while a dramatic reduction in this number was observed following immunosuppression and neutropenia. Interestingly, a slight increase in the infiltration of neutrophils into the airway wall was detected as a result of infection, even in immunosuppressed and neutropenic mice. Taken together, these data indicate that neutrophils are present in intact conducting airway walls and the number elevates upon A. fumigatus infection. Conducting airway wall neutrophils are affected by both neutropenia and immunosuppression. PMID- 29577052 TI - Frequency of Interferon-Resistance Conferring Substitutions in Amino Acid Positions 70 and 91 of Core Protein of the Russian HCV 1b Isolates Analyzed in the T-Cell Epitopic Context. AB - Amino acid substitutions R70Q/H and L91M in HCV subtype 1b core protein can affect the response to interferon and are associated with the development of hepatocellular carcinoma. We found that the rate of R70Q/H in HCV 1b from Russia was 31.2%, similar to that in HCV strains from Asia (34.0%), higher than that in the European (18.0%, p = 0.0010), but lower than that in the US HCV 1b strains (62.8%, p < 0.0001). Substitution L91M was found in 80.4% of the Russian HCV 1b isolates, higher than in Asian isolates (43.8%, p < 0.0001). Thus, a significant proportion of Russian HCV 1b isolates carry the unfavorable R70Q/H and/or L91M substitution. In silico analysis of the epitopic structure of the regions of substitutions revealed that both harbor clusters of T-cell epitopes. Peptides encompassing these regions were predicted to bind to a panel of HLA class I molecules, with substitutions impairing peptide recognition by HLA I molecules of the alleles prevalent in Russia. This indicates that HCV 1b with R70Q/H and L91M substitutions may have evolved as the immune escape variants. Impairment of T cell recognition may play a part in the negative effect of these substitutions on the response to IFN treatment. PMID- 29577053 TI - Hsa_circ_0001859 Regulates ATF2 Expression by Functioning as an MiR-204/211 Sponge in Human Rheumatoid Arthritis. AB - Background: circRNAs are part of the competitive endogenous RNA network, which putatively function as miRNA sponges and play a crucial role in the development of numerous diseases. However, studies of circRNAs in rheumatoid arthritis (RA) disease are limited. This work aims to identify the expression pattern of circRNAs in synovial tissues and their inflammatory regulation mechanism. Methods: We first compared the mRNA expression in rheumatoid arthritis patients with that in healthy volunteers by GEO database mining to identify gene loci specifically expressed in synovial tissues. Functional enrichment algorithms were then used to draw the interactome diagram of circRNAs-miRNAs-mRNAs. Finally, loss of-function and rescue assays of the candidate circRNAs were performed in vitro. Results: A total of 29 differentially expressed circRNAs related to rheumatoid arthritis were discovered. Silencing of hsa_circ_0001859 suppressed ATF2 expression and decreased inflammatory activity in SW982 cells. Hsa_circ_0001859 could compete with ATF2 for miR-204/211. Discussion: These findings indicate that hsa_circ_0001859 participates deeply in the process of chronic inflammatory disease in synovial tissue. PMID- 29577055 TI - Perianal Mucinous Adenocarcinoma Diagnosed by Histological Study of Anorectal Abscess with Fistula. AB - Perianal mucinous adenocarcinoma (PMA) is an oncologic rarity that poses a diagnostic and therapeutic dilemma for treating clinicians because there are few reported cases and an absence of definitive guidelines. We report a patient who had been treated with local surgery for recurrent perianal abscess with fistula for 3 years. Biopsy of the indurated tissue overlying his surgical scars revealed PMA. Neoadjuvant concurrent chemoradiotherapy followed by abdominoperineal resection was planned to address the locally advanced disease and ongoing sepsis. Our case is unique in that the fistula preceded carcinoma by only 3 years instead of the typical 10 years. PMID- 29577054 TI - Successful Treatment of Bleeding Rectal Varices with Balloon-Occluded Antegrade Transvenous Obliteration. AB - We report the first described case in the United States of balloon-occluded antegrade transvenous obliteration (BATO) performed in a cirrhotic patient with recurrent bleeding from large rectal varices. This is a novel interventional radiology approach to treat bleeding rectal varices. Our patient was a poor candidate for transjugular intrahepatic portosystemic shunt and endoscopic band ligation. Successful BATO produced complete resolution of rectal varices and no further rectal bleeding. There are no established guidelines for the management of rectal varices. We demonstrate that the BATO technique is a viable option to treat recurrent bleeding due to rectal varices. PMID- 29577056 TI - An Overt, Obscure Gastrointestinal Bleed Caused by a Primary Small Bowel Fibroblastic Reticular Cell Sarcoma. AB - Small bowel bleeding should be considered in patients who continue to bleed despite a negative upper endoscopy and colonoscopy. The differential diagnosis of small bowel bleeding can include infection, inflammatory conditions, vascular malformations, and, rarely, malignancy. This report demonstrates a rare, primary, small bowel, reticular cell sarcoma presenting as an overt gastrointestinal bleed. These tumors are difficult to diagnose because they are rarely seen on traditional cross-sectional imaging and can present with multiple synchronous lesions throughout the intestinal tract. PMID- 29577057 TI - Malignant Peritoneal Mesothelioma Presenting as Mucinous Ascites. AB - We present a rare case of a 46-year-old man presenting with mucinous ascites secondary to malignant peritoneal mesothelioma (MPM) that was diagnosed via colonoscopy with biopsies. Both our findings and the clinical presentation were unique. While it is widely known that asbestos exposure is commonly associated with pleural mesothelioma, 6-10% of malignant mesotheliomas arise from the peritoneum. To date, only 4 cases of MPM with the primary tumor site in the colon have been described in the literature. PMID- 29577058 TI - Infectious Diseases Consultation Reduces 30-Day and 1-Year All-Cause Mortality for Multidrug-Resistant Organism Infections. AB - Background: Multidrug-resistant organism (MDRO) infections are associated with high mortality and readmission rates. Infectious diseases (ID) consultation improves clinical outcomes for drug-resistant Staphylococcus aureus bloodstream infections. Our goal was to determine the association between ID consultation and mortality following various MDRO infections. Methods: This study was conducted with a retrospective cohort (January 1, 2006-October 1, 2015) at an academic tertiary referral center. We identified patients with MDROs in a sterile site or bronchoalveolar lavage/bronchial wash culture. Mortality and readmissions within 1 year of index culture were identified, and the association of ID consultation with these outcomes was determined using Cox proportional hazards models with inverse weighting by the propensity score for ID consultation. Results: A total of 4214 patients with MDRO infections were identified. ID consultation was significantly associated with reductions in 30-day and 1-year mortality for resistant S. aureus (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.36 0.63; and HR, 0.73, 95% CI, 0.61-0.86) and Enterobacteriaceae (HR, 0.41; 95% CI, 0.27-0.64; and HR, 0.74; 95% CI, 0.59-0.94), and 30-day mortality for polymicrobial infections (HR, 0.51; 95% CI, 0.31-0.86) but not Acinetobacter or Pseudomonas. For resistant Enterococcus, ID consultation was marginally associated with decreased 30-day mortality (HR, 0.81; 95% CI, 0.62-1.06). ID consultation was associated with reduced 30-day readmission for resistant Enterobacteriaceae. Conclusions: ID consultation was associated with significant reductions in 30-day and 1-year mortality for resistant S. aureus and Enterobacteriaceae, and 30-day mortality for polymicrobial infections. There was no association between ID consultation and mortality for patients with resistant Pseudomonas, Acinetobacter, or Enterococcus, possibly due to small sample sizes. Our results suggest that ID consultation may be beneficial for patients with some MDRO infections.

AB - Housing instability negatively impacts outcomes in people [living] with human immunodeficiency virus (PLHIV), yet the effect of diverse living arrangements has not previously been evaluated. Using 6 dwelling types to measure housing status, we found a strong inverse association between housing instability and viral suppression across a spectrum of unstable housing arrangements.

We describe 3 cases of splenic infarction attributed to infectious mononucleosis that we encountered within a 2-month period. We underscore the awareness of this potential complication of infectious mononucleosis and discuss the differential diagnosis of splenic infarction, including infectious etiologies. While symptomatic management is usually sufficient for infectious mononucleosis associated splenic infarction, close monitoring for other complications, including splenic rupture, is mandated. PMID- 29577061 TI - Spatial Control of Bacteria Using Screen Printing. AB - Synthetic biology has led to advances in both our understanding and engineering of genetic circuits that affect spatial and temporal behaviors in living cells. A growing array of native and synthetic circuits such as oscillators, pattern generators, and cell-cell communication systems has been studied, which exhibit spatiotemporal properties. To better understand the design principles of these genetic circuits, there is a need for versatile and precise methods for patterning cell populations in various configurations. In this study, we develop a screen printing methodology to pattern bacteria on agar, glass, and paper surfaces. Initially, we tested three biocompatible resuspension media with appropriate rheological properties for screen printing. Using microscopy, we characterized the resolution and bleed of bacteria screen prints on agar and glass surfaces, obtaining resolutions as low as 188 MUm. Next, we engineered bacterial strains producing visible chromoproteins analogous to the cyan, magenta, and yellow subtractive color system for the creation of multicolored bacteria images. Using this system, we printed distinct populations in overlapping or interlocking designs on both paper and agar substrates. These proof-of-principle experiments demonstrated how the screen printing method could be used to study microbial community interactions and pattern formation of biofilms at submillimeter length scales. Overall, our approach allows for rapid and precise prototyping of patterned bacteria species that will be useful in the understanding and engineering of spatiotemporal behaviors in microbial communities. PMID- 29577062 TI - Conformal Robotic Stereolithography. AB - Additive manufacturing by layerwise photopolymerization, commonly called stereolithography (SLA), is attractive due to its high resolution and diversity of materials chemistry. However, traditional SLA methods are restricted to planar substrates and planar layers that are perpendicular to a single-axis build direction. Here, we present a robotic system that is capable of maskless layerwise photopolymerization on curved surfaces, enabling production of large area conformal patterns and the construction of conformal freeform objects. The system comprises an industrial six-axis robot and a custom-built maskless projector end effector. Use of the system involves creating a mesh representation of the freeform substrate, generation of a triangulated toolpath with curved layers that represents the target object to be printed, precision mounting of the substrate in the robot workspace, and robotic photopatterning of the target object by coordinated motion of the robot and substrate. We demonstrate printing of conformal photopatterns on spheres of various sizes, and construction of miniature three-dimensional objects on spheres without requiring support features. Improvement of the motion accuracy and development of freeform toolpaths would enable construction of polymer objects that surpass the size and support structure constraints imparted by traditional SLA systems. PMID- 29577063 TI - Association between Metabolic Syndrome and Recurrence of Nonmuscle Invasive Bladder Cancer following bacillus Calmette-Guerin Treatment. AB - Introduction: Intravesical bacillus Calmette-Guerin (BCG) therapy is the gold standard adjuvant treatment for patients with high-grade non-muscle-invasive bladder cancer (NMIBC). Despite the association between metabolic syndrome (MetS) and bladder cancer, the association between MetS and BCG failure is unknown. The objective of this study was to characterize disease recurrence following BCG in patients with and without MetS. Methods: We retrospectively evaluated the records of patients undergoing TURBT at our institution in 2012-2015 for NMIBC and identified those who received adjuvant BCG therapy. MetS was defined as having three of four components: diabetes mellitus, hyperlipidemia, hypertension, or body mass index (BMI)>=30kg/m2. The primary outcome was recurrence or progression. Descriptive statistics, chi-squared analysis, Kaplan-Meier survival analysis, and Cox multivariable regression analyses were performed. Results: High grade was present in 83/90 (92.2%) patients. MetS was present in 27/90 (30%) patients. Median follow-up was 20 months. On Kaplan-Meier analysis, patients with MetS had worse DFS compared with patient without MetS. On multivariable analysis, BMI>=30 kg/m2 was a significant predictor of recurrence or progression (HR 2.94, 95% CI: 1.43-6.03). Presence of MetS did not significantly affect the type of BCG failure. Conclusions: The association between MetS and failure to respond to BCG therapy is multifactorial but is in part associated with obesity. Elevated BMI is strongly associated with recurrence or progression. Further studies are warranted to investigate the relationship between increased adiposity and response to BCG, especially as other novel immunotherapeutic agents are likely to enter the NMIBC space. PMID- 29577064 TI - Functionalization of PCL-3D Electrospun Nanofibrous Scaffolds for Improved BMP2 Induced Bone Formation. AB - Bone morphogenic protein 2 (BMP2) is a key growth factor for bone regeneration, possessing FDA approval for orthopedic applications. BMP2 is often required in supratherapeutic doses clinically, yielding adverse side effects and substantial treatment costs. Considering the crucial role of materials for BMPs delivery and cell osteogenic differentiation, we devote to engineering an innovative bone matrix mimicking niche to improve low dose of BMP2-induced bone formation. Our previous work describes a novel technique, named thermally induced nanofiber self agglomeration (TISA), for generating 3D electrospun nanofibrous (NF) polycaprolactone (PCL) scaffolds. TISA process could readily blend PCL with PLA, leading to increased osteogenic capabilities in vitro, however, these bio-inert synthetic polymers produced limited BMP2-induced bone formation in vivo. We therefore hypothesize that functionalization of NF 3D PCL scaffolds with bone like hydroxyapatite (HA) and BMP2 signaling activator phenamil will provide a favorable osteogenic niche for bone formation at low doses of BMP2. Compared to PCL-3D scaffolds, PCL/HA-3D scaffolds demonstrated synergistically enhanced osteogenic differentiation capabilities of C2C12 cells with phenamil. Importantly, in vivo studies showed this synergism was able to generate significantly increased new bone in an ectopic mouse model, suggesting PCL/HA-3D scaffolds act as a favorable synthetic extracellular matrix for bone regeneration. PMID- 29577065 TI - Docking-based inverse virtual screening: methods, applications, and challenges. AB - Identifying potential protein targets for a small-compound ligand query is crucial to the process of drug development. However, there are tens of thousands of proteins in human alone, and it is almost impossible to scan all the existing proteins for a query ligand using current experimental methods. Recently, a computational technology called docking-based inverse virtual screening (IVS) has attracted much attention. In docking-based IVS, a panel of proteins is screened by a molecular docking program to identify potential targets for a query ligand. Ever since the first paper describing a docking-based IVS program was published about a decade ago, the approach has been gradually improved and utilized for a variety of purposes in the field of drug discovery. In this article, the methods employed in docking-based IVS are reviewed in detail, including target databases, docking engines, and scoring function methodologies. Several web servers developed for non-expert users are also reviewed. Then, a number of applications are presented according to different research purposes, such as target identification, side effects/toxicity, drug repositioning, drug-target network development, and receptor design. The review concludes by discussing the challenges that docking-based IVS needs to overcome to become a robust tool for pharmaceutical engineering. PMID- 29577066 TI - AIM interneurons mediate feeding suppression through the TYRA-2 receptor in C. elegans. AB - Feeding behavior is the most fundamental behavior in C. elegans. Our previous results have dissected the central integration circuit for the regulation of feeding, which integrates opposing sensory inputs and regulates feeding behavior in a nonlinear manner. However, the peripheral integration that acts downstream of the central integration circuit to modulate feeding remains largely unknown. Here, we find that a Galphai/o-coupled tyramine receptor, TYRA-2, is involved in peripheral feeding suppression. TYRA-2 suppresses feeding behavior via the AIM interneurons, which receive tyramine/octopamine signals from RIM/RIC neurons in the central integration circuit. Our results reveal previously unidentified roles for the receptor TYRA-2 and the AIM interneurons in feeding regulation, providing a further understanding of how biogenic amines tyramine and octopamine regulate feeding behavior. PMID- 29577067 TI - PI4KIIalpha regulates insulin secretion and glucose homeostasis via a PKD dependent pathway. AB - Insulin release by pancreatic beta cells plays a key role in regulating blood glucose levels in humans, and to understand the mechanism for insulin secretion may reveal therapeutic strategies for diabetes. We found that PI4KIIalpha transgenic (TG) mice have abnormal glucose tolerance and higher serum glucose levels than wild-type mice. Glucose-stimulated insulin secretion was significantly reduced in both PI4KIIalpha TG mice and PI4KIIalpha-overexpressing pancreatic beta cell lines. A proximity-based biotin labeling technique, BioID, was used to identify proteins that interact with PI4KIIalpha, and the results revealed that PI4KIIalpha interacts with PKD and negatively regulates its activity. The effect of PI4KIIalpha on insulin secretion was completely rescued by altering PKD activity. PI4KIIalpha overexpression also worsened glucose tolerance in streptozotocin/high-fat diet-induced diabetic mice by impairing insulin secretion. Our study has shed new light on PI4KIIalpha function and mechanism in diabetes and identified PI4KIIalpha as an important regulator of insulin secretion. PMID- 29577068 TI - Identification of small ORF-encoded peptides in mouse serum. AB - Identification of the coding elements in the genome is fundamental to interpret the development of living systems and species diversity. Small peptides (length < 100 amino acids) have played an important role in regulating the biological metabolism, but their identification has been limited by their size and abundance. Serum is the most important body fluid and is full of small peptides. In this study, we have established a small ORF-encoded peptides (SEPs) database from mouse GENCODE release. This database provides about half a million putative translated SEPs in mouse. We also extract serum proteins from wild type and ob/ob mice, and collect the low molecular weight proteins for mass spectrometric analysis. More than 50 novel SEPs have been discovered. Several SEPs are further verified by biochemical method with newly raised antibodies. These novel SEPs enhance the knowledge about the complexity of serum and provide new clues for the annotation and functional analysis of genes, especially the noncoding elements in the genome. PMID- 29577069 TI - Identification of natural products as novel ligands for the human 5-HT2C receptor. AB - G protein-coupled receptors (GPCRs) constitute the largest human protein family with over 800 members, which are implicated in many important medical conditions. Serotonin receptors belong to the aminergic GPCR subfamily and play important roles in physiological and psychological activities. Structural biology studies have revealed the structures of many GPCRs in atomic details and provide the basis for the identification and investigation of the potential ligands, which interact with and modulate the receptors. Here, an integrative approach combining a focused target-specific natural compound library, a thermal-shift-based screening method, affinity mass spectrometry, molecular docking, and in vitro as well as in vivo functional assay, was applied to identify (-)-crebanine and several other aporphine alkaloids as initial hits for a human serotonin receptor subtype, the 5-HT2C receptor. Further studies illuminated key features of their binding affinity, downstream signaling and tissue reaction, providing a molecular explanation for the interaction between (-)-crebanine and human 5-HT2C receptor. PMID- 29577070 TI - A new two-strip TLC method for the quality control of technetium-99m mercaptoacetyl-triglycine (99mTc-MAG3). AB - Background: 99mTc-mercaptoacetyl-triglycine (99mTc-MAG3) has been used for dynamic renal imaging since about 30 years. Free pertechnetate (99mTcO4), colloidal 99mTc ((99mTcO2)n), 99mTc-tartrate (precursor), precomplexes (99mTc (MAG3)x) and lipophilic 99mTc-MAG2 are the main radiochemical impurities that may occur in the preparation. The total amount of these impurities has to be identified before release of the product for patient administration to guarantee patient safety and good image quality. The European Pharmacopoeia suggests a method based on high-pressure liquid chromatography analysis in combination with a paper chromatography. This analytical method is time consuming, expensive and requires specially trained technicians. As a consequence, it is not widely applied in nuclear medicine radiopharmacies. Results: We developed a simple method for radiochemical purity testing of 99mTc-MAG3. The method is based on thin layer chromatography with two strips to be developed in parallel. Method validation was carried out in comparison to the official methods of the companies and to the European Pharmacopoeia method. It was tested on specificity, accuracy, robustness and precision. Conclusion: The proposed method is able to identify and quantify the sum of all impurities occurring in the preparation, respecting the acceptance criteria for the radiochemical purity defined by the official methods. Hydrophilic and lipophilic compounds are identified separately and results are obtained within less than 20 minutes. Our method is simple, cost effective, fast and is suitable for employing dose calibrators or radiometric scanners. PMID- 29577071 TI - Temporal fractals in movies and mind. AB - Fractal patterns are seemingly everywhere. They can be analyzed through Fourier and power analyses, and other methods. Cutting, DeLong, and Nothelfer (2010) analyzed as time-series data the fluctuations of shot durations in 150 popular movies released over 70 years. They found that these patterns had become increasingly fractal-like and concluded that they might be linked to those found in the results of psychological tasks involving attention. To explore this possibility further, we began by analyzing the shot patterns of almost twice as many movies released over a century. The increasing fractal-like nature of shot patterns is affirmed, as determined by both a slope measure and a long-range dependence measure, neither of which is sensitive to the vector lengths of their inputs within the ranges explored here. But the main reason for increased long range dependence is related to, but not caused by, the increasing vector length of the shot-series samples. It appears that, in generating increasingly fractal like patterns, filmmakers have systematically explored dimensions that are important for holding our attention-shot durations, scene durations, motion, and sound amplitude-and have crafted fluctuations in them like those of our endogenous attention patterns. Other dimensions-luminance, clutter, and shot scale-are important to film style but their variations seem not to be important to holding viewers' moment-to-moment attention and have not changed in their fractional dimension over time. PMID- 29577072 TI - Theoretical vs. empirical discriminability: the application of ROC methods to eyewitness identification. AB - Receiver operating characteristic (ROC) analysis was introduced to the field of eyewitness identification 5 years ago. Since that time, it has been both influential and controversial, and the debate has raised an issue about measuring discriminability that is rarely considered. The issue concerns the distinction between empirical discriminability (measured by area under the ROC curve) vs. underlying/theoretical discriminability (measured by d' or variants of it). Under most circumstances, the two measures will agree about a difference between two conditions in terms of discriminability. However, it is possible for them to disagree, and that fact can lead to confusion about which condition actually yields higher discriminability. For example, if the two conditions have implications for real-world practice (e.g., a comparison of competing lineup formats), should a policymaker rely on the area-under-the-curve measure or the theory-based measure? Here, we illustrate the fact that a given empirical ROC yields as many underlying discriminability measures as there are theories that one is willing to take seriously. No matter which theory is correct, for practical purposes, the singular area-under-the-curve measure best identifies the diagnostically superior procedure. For that reason, area under the ROC curve informs policy in a way that underlying theoretical discriminability never can. At the same time, theoretical measures of discriminability are equally important, but for a different reason. Without an adequate theoretical understanding of the relevant task, the field will be in no position to enhance empirical discriminability. PMID- 29577073 TI - An assigned responsibility system for robotic teleoperation control. AB - This paper proposes an architecture that explores a gap in the spectrum of existing strategies for robot control mode switching in adjustable autonomy. In situations where the environment is reasonably known and/or predictable, pre planning these control changes could relieve robot operators of the additional task of deciding when and how to switch. Such a strategy provides a clear division of labour between the automation and the human operator(s) before the job even begins, allowing for individual responsibilities to be known ahead of time, limiting confusion and allowing rest breaks to be planned. Assigned Responsibility is a new form of adjustable autonomy-based teleoperation that allows the selective inclusion of automated control elements at key stages of a robot operation plan's execution. Progression through these stages is controlled by automatic goal accomplishment tracking. An implementation is evaluated through engineering tests and a usability study, demonstrating the viability of this approach and offering insight into its potential applications. PMID- 29577074 TI - An enhanced teaching interface for a robot using DMP and GMR. AB - This paper develops an enhanced teaching interface tested on both a Baxter robot and a KUKA iiwa robot. Movements are collected from a human demonstrator by using a Kinect v2 sensor, and then the data is sent to a remote PC for the teleoperation with Baxter. Meanwhile, data is saved locally for the playback process of the Baxter. The dynamic movement primitive (DMP) is used to model and generalize the movements. In order to learn from multiple demonstrations accurately, dynamic time warping (DTW), is used to pretreat the data recorded by the robot platform and Gaussian mixture model (GMM), aiming to generate multiple patterns after the teaching process, are employed for the calculation of the DMP. Then the Gaussian mixture regression (GMR) algorithm is applied to generate a synthesized trajectory with smaller position errors in 3D space. This proposed approach is tested by performing two tasks on a KUKA iiwa and a Baxter robot. PMID- 29577075 TI - Understanding Two Different Structures in the Dark Stable State of the Oxygen Evolving Complex of Photosystem II: Applicability of the Jahn-Teller Deformation Formula. AB - Tanaka et al. (J. Am. Chem. Soc., 2017, 139, 1718) recently reported the three dimensional (3D) structure of the oxygen evolving complex (OEC) of photosystem II (PSII) by X-ray diffraction (XRD) using extremely low X-ray doses of 0.03 and 0.12 MGy. They observed two different 3D structures of the CaMn4O5 cluster with different hydrogen-bonding interactions in the S1 state of OEC keeping the surrounding polypeptide frameworks of PSII the same. Our Jahn-Teller (JT) deformation formula based on large-scale quantum mechanics/molecular mechanics (QM/MM) was applied for these low-dose XRD structures, elucidating important roles of JT effects of the MnIII ion for subtle geometric distortions of the CaMn4O5 cluster in OEC of PSII. The JT deformation formula revealed the similarity between the low-dose XRD and damage-free serial femtosecond X-ray diffraction (SFX) structures of the CaMn4O5 cluster in the dark stable state. The extremely low-dose XRD structures were not damaged by X-ray irradiation. Implications of the present results are discussed in relation to recent SFX results and a blue print for the design of artificial photocatalysts for water oxidation. PMID- 29577076 TI - Neoadjuvant Chemotherapy Considerations in Triple-Negative Breast Cancer. AB - The optimal neoadjuvant chemotherapy (NACT) regimen in triple-negative breast cancer (TNBC) has not been clearly defined. Achieving a pathologic complete response (pCR) provides important prognostic information, and, especially in TNBC, is considered a surrogate endpoint for event-free survival. Thus, many neoadjuvant studies in TNBC focus on this as a primary endpoint, and such information may be used for accelerated US Food and Drug Administration approval. Current controversies in the field include: (1) the role of platinum-based compounds; (2) the optimal chemotherapy backbone; and (3) the benefits of additional therapy after surgery. Conflicting results of 2 major studies adding carboplatin to NACT have highlighted the need to balance potential benefits to disease outcomes against increased toxicity. While the PROGECT study suggests efficacy of a nonanthracycline-containing regimen, this is observational data, and evidence in the form of a clinical trial remains to be seen. Data surrounding optimal taxane use support the use of nab-paclitaxel in place of paclitaxel in limited clinical situations. Although bevacizumab may increase pCR rates, this has not translated into survival benefit. Capecitabine shows promise in patients who have not achieved pCR after NACT. The neoadjuvant setting remains an important model for drug development. This review will focus on the most important and most current neoadjuvant trials in women with TNBC. PMID- 29577077 TI - ACO2 homozygous missense mutation associated with complicated hereditary spastic paraplegia. AB - Objective: To identify the clinical characteristics and genetic etiology of a family affected with hereditary spastic paraplegia (HSP). Methods: Clinical, genetic, and functional analyses involving genome-wide linkage coupled to whole exome sequencing in a consanguineous family with complicated HSP. Results: A homozygous missense mutation was identified in the ACO2 gene (c.1240T>G p.Phe414Val) that segregated with HSP complicated by intellectual disability and microcephaly. Lymphoblastoid cell lines of homozygous carrier patients revealed significantly decreased activity of the mitochondrial aconitase enzyme and defective mitochondrial respiration. ACO2 encodes mitochondrial aconitase, an essential enzyme in the Krebs cycle. Recessive mutations in this gene have been previously associated with cerebellar ataxia. Conclusions: Our findings nominate ACO2 as a disease-causing gene for autosomal recessive complicated HSP and provide further support for the central role of mitochondrial defects in the pathogenesis of HSP. PMID- 29577078 TI - Rare ABCA7 variants in 2 German families with Alzheimer disease. AB - Objective: The aim of this study was to identify variants associated with familial late-onset Alzheimer disease (AD) using whole-genome sequencing. Methods: Several families with an autosomal dominant inheritance pattern of AD were analyzed by whole-genome sequencing. Variants were prioritized for rare, likely pathogenic variants in genes already known to be associated with AD and confirmed by Sanger sequencing using standard protocols. Results: We identified 2 rare ABCA7 variants (rs143718918 and rs538591288) with varying penetrance in 2 independent German AD families, respectively. The single nucleotide variant (SNV) rs143718918 causes a missense mutation, and the deletion rs538591288 causes a frameshift mutation of ABCA7. Both variants have previously been reported in larger cohorts but with incomplete segregation information. ABCA7 is one of more than 20 AD risk loci that have so far been identified by genome-wide association studies, and both common and rare variants of ABCA7 have previously been described in different populations with higher frequencies in AD cases than in controls and varying penetrance. Furthermore, ABCA7 is known to be involved in several AD-relevant pathways. Conclusions: We conclude that both SNVs might contribute to the development of AD in the examined family members. Together with previous findings, our data confirm ABCA7 as one of the most relevant AD risk genes.

PMID- 29577081 TI - Pharmacogenetic Associations with ADME Variants and Virologic Response to an Initial HAART Regimen in HIV-Infected Women. AB - Background: Clinical response to highly active antiretroviral therapy (HAART) varies among different populations. A portion of this variability may be due to variation in genes involved in the absorption, distribution, metabolism, and excretion (ADME) of HAART. Design: To identify genetic factors involved in virologic responses to HAART, 13 genes in ADME pathways were analyzed in a cohort of HIV-infected women on HAART. A total of 569 HIV-positive participants from the Women's Interagency HIV Study who initiated HAART from 1994-2012 and had genotype data were included in these analyses. Methods: Admixture maximum likelihood burden testing was used to evaluate gene-level associations between common genetic variation and virologic response (achieving <80 viral copies/mL) to HAART overall and with specific drug classes. Results: Six statistically significant (P<0.05) gene-level burden tests were observed with response to specific regimen types. CYP2B6, CYP2C19 and CYP2C9 were significantly associated with response to protease inhibitor (PI)-based regimens. CYP2C9, ADH1A and UGT1A1 were significantly associated with response to triple nucleoside reverse transcriptase inhibitor (NRTI) treatment. Conclusions: Although no genome-wide associations with virologic response to HAART overall were detected in this cohort of HIV infected women, more statistically significant gene-level burden tests were observed than would be expected by chance (two and a half expected, six observed). It is likely that variation in one of the significant genes is associated with virologic response to certain HAART regimens. Further characterization of the genes associated with response to PI-based treatment is warranted. PMID- 29577082 TI - Talaromyces marneffei simA Encodes a Fungal Cytochrome P450 Essential for Survival in Macrophages. AB - Fungi are adept at occupying specific environmental niches and often exploit numerous secondary metabolites generated by the cytochrome P450 (CYP) monoxygenases. This report describes the characterization of a yeast-specific CYP encoded by simA ("survival in macrophages"). Deletion of simA does not affect yeast growth at 37 degrees C in vitro but is essential for yeast cell production during macrophage infection. The DeltasimA strain exhibits reduced conidial germination and intracellular growth of yeast in macrophages, suggesting that the enzymatic product of SimA is required for normal fungal growth in vivo. Intracellular DeltasimA yeast cells exhibit cell wall defects, and metabolomic and chemical sensitivity data suggest that SimA may promote chitin synthesis or deposition in vitro. In vivo, DeltasimA yeast cells subsequently lyse and are degraded, suggesting that SimA may increase resistance to and/or suppress host cell biocidal effectors. The results suggest that simA synthesizes a secondary metabolite that allows T. marneffei to occupy the specific intracellular environmental niche within the macrophage. IMPORTANCE This study in a dimorphic fungal pathogen uncovered a role for a yeast-specific cytochrome P450 (CYP) encoding gene in the ability of T. marneffei to grow as yeast cells within the host macrophages. This report will inspire further research into the role of CYPs and secondary metabolite synthesis during fungal pathogenic growth. PMID- 29577083 TI - Human Antibody Responses to Emerging Mayaro Virus and Cocirculating Alphavirus Infections Examined by Using Structural Proteins from Nine New and Old World Lineages. AB - Mayaro virus (MAYV), Venezuelan equine encephalitis virus (VEEV), and chikungunya virus (CHIKV) are vector-borne alphaviruses that cocirculate in South America. Human infections by these viruses are frequently underdiagnosed or misdiagnosed, especially in areas with high dengue virus endemicity. Disease may progress to debilitating arthralgia (MAYV, CHIKV), encephalitis (VEEV), and death. Few standardized serological assays exist for specific human alphavirus infection detection, and antigen cross-reactivity can be problematic. Therefore, serological platforms that aid in the specific detection of multiple alphavirus infections will greatly expand disease surveillance for these emerging infections. In this study, serum samples from South American patients with PCR- and/or isolation-confirmed infections caused by MAYV, VEEV, and CHIKV were examined by using a protein microarray assembled with recombinant capsid, envelope protein 1 (E1), and E2 from nine New and Old World alphaviruses. Notably, specific antibody recognition of E1 was observed only with MAYV infections, whereas E2 was specifically targeted by antibodies from all of the alphavirus infections investigated, with evidence of cross-reactivity to E2 of o'nyong-nyong virus only in CHIKV-infected patient serum samples. Our findings suggest that alphavirus structural protein microarrays can distinguish infections caused by MAYV, VEEV, and CHIKV and that this multiplexed serological platform could be useful for high-throughput disease surveillance. IMPORTANCE Mayaro, chikungunya, and Venezuelan equine encephalitis viruses are closely related alphaviruses that are spread by mosquitos, causing diseases that produce similar influenza-like symptoms or more severe illnesses. Moreover, alphavirus infection symptoms can be similar to those of dengue or Zika disease, leading to underreporting of cases and potential misdiagnoses. New methods that can be used to detect antibody responses to multiple alphaviruses within the same assay would greatly aid disease surveillance efforts. However, possible antibody cross reactivity between viruses can reduce the quality of laboratory results. Our results demonstrate that antibody responses to multiple alphaviruses can be specifically quantified within the same assay by using selected recombinant protein antigens and further show that Mayaro virus infections result in unique responses to viral envelope proteins. PMID- 29577084 TI - Aggregative Adherence and Intestinal Colonization by Enteroaggregative Escherichia coli Are Produced by Interactions among Multiple Surface Factors. AB - Enteroaggregative Escherichia coli (EAEC) bacteria are exceptional colonizers that are associated with diarrhea. The genome of EAEC strain 042, a diarrheal pathogen validated in a human challenge study, encodes multiple colonization factors. Notable among them are aggregative adherence fimbriae (AAF/II) and a secreted antiaggregation protein (Aap). Deletion of aap is known to increase adherence, autoaggregation, and biofilm formation, so it was proposed that Aap counteracts AAF/II-mediated interactions. We hypothesized that Aap sterically masks heat-resistant agglutinin 1 (Hra1), an integral outer membrane protein recently identified as an accessory colonization factor. We propose that this masking accounts for reduced in vivo colonization upon hra1 deletion and yet no colonization-associated phenotypes when hra1 is deleted in vitro. Using single and double mutants of hra1, aap, and the AAF/II structural protein gene aafA, we demonstrated that increased adherence in aap mutants occurs even when AAF/II proteins are genetically or chemically removed. Deletion of hra1 together with aap abolishes the hyperadherence phenotype, demonstrating that Aap indeed masks Hra1. The presence of all three colonization factors, however, is necessary for optimal colonization and for rapidly building stacked-brick patterns on slides and cultured monolayers, the signature EAEC phenotype. Altogether, our data demonstrate that Aap serves to mask nonstructural adhesins such as Hra1 and that optimal colonization by EAEC is mediated through interactions among multiple surface factors. IMPORTANCE Enteroaggregative Escherichia coli (EAEC) bacteria are exceptional colonizers of the human intestine and can cause diarrhea. Compared to other E. coli pathogens, little is known about the genes and pathogenic mechanisms that differentiate EAEC from harmless commensal E. coli. EAEC bacteria attach via multiple proteins and structures, including long appendages produced by assembling molecules of AafA and a short surface protein called Hra1. EAEC also secretes an antiadherence protein (Aap; also known as dispersin) which remains loosely attached to the cell surface. This report shows that dispersin covers Hra1 such that the adhesive properties of EAEC seen in the laboratory are largely produced by AafA structures. When the bacteria colonize worms, dispersin is sloughed off, or otherwise removed, such that Hra1-mediated adherence occurs. All three factors are required for optimal colonization, as well as to produce the signature EAEC stacked-brick adherence pattern. Interplay among multiple colonization factors may be an essential feature of exceptional colonizers. PMID- 29577085 TI - Evolution of Bacterial Global Modulators: Role of a Novel H-NS Paralogue in the Enteroaggregative Escherichia coli Strain 042. AB - Bacterial genomes sometimes contain genes that code for homologues of global regulators, the function of which is unclear. In members of the family Enterobacteriaceae, cells express the global regulator H-NS and its paralogue StpA. In Escherichia coli, out of providing a molecular backup for H-NS, the role of StpA is poorly characterized. The enteroaggregative E. coli strain 042 carries, in addition to the hns and stpA genes, a third gene encoding an hns paralogue (hns2). We present in this paper information about its biological function. Transcriptomic analysis has shown that the H-NS2 protein targets a subset of the genes targeted by H-NS. Genes targeted by H-NS2 correspond mainly with horizontally transferred (HGT) genes and are also targeted by the Hha protein, a fine-tuner of H-NS activity. Compared with H-NS, H-NS2 expression levels are lower. In addition, H-NS2 expression exhibits specific features: it is sensitive to the growth temperature and to the nature of the culture medium. This novel H-NS paralogue is widespread within the Enterobacteriaceae. IMPORTANCE Global regulators such as H-NS play key relevant roles enabling bacterial cells to adapt to a changing environment. H-NS modulates both core and horizontally transferred (HGT) genes, but the mechanism by which H-NS can differentially regulate these genes remains to be elucidated. There are several instances of bacterial cells carrying genes that encode homologues of the global regulators. The question is what the roles of these proteins are. We noticed that the enteroaggregative E. coli strain 042 carries a new hitherto uncharacterized copy of the hns gene. We decided to investigate why this pathogenic E. coli strain requires an extra H-NS paralogue, termed H-NS2. In our work, we show that H-NS2 displays specific expression and regulatory properties. H-NS2 targets a subset of H-NS-specific genes and may help to differentially modulate core and HGT genes by the H-NS cellular pool.

AB - Microbiome analyses of low-biomass samples are challenging because of contamination and inefficiencies, leading many investigators to employ low throughput methods with minimal controls. We developed a new automated protocol, KatharoSeq (from the Greek katharos [clean]), that outperforms single-tube extractions while processing at least five times as fast. KatharoSeq incorporates positive and negative controls to reveal the whole bacterial community from inputs of as few as 50 cells and correctly identifies 90.6% (standard error, 0.013%) of the reads from 500 cells. To demonstrate the broad utility of KatharoSeq, we performed 16S rRNA amplicon and shotgun metagenome analyses of the Jet Propulsion Laboratory spacecraft assembly facility (SAF; n = 192, 96), 52 rooms of a neonatal intensive care unit (NICU; n = 388, 337), and an endangered abalone-rearing facility (n = 192, 123), obtaining spatially resolved, unique microbiomes reproducible across hundreds of samples. The SAF, our primary focus, contains 32 sOTUs (sub-OTUs, defined as exact sequence matches) and their inferred variants identified by the deblur algorithm, with four (Acinetobacter lwoffii, Paracoccus marcusii, Mycobacterium sp., and Novosphingobium) being present in >75% of the samples. According to microbial spatial topography, the most abundant cleanroom contaminant, A. lwoffii, is related to human foot traffic exposure. In the NICU, we have been able to discriminate environmental exposure related to patient infectious disease, and in the abalone facility, we show that microbial communities reflect the marine environment rather than human input. Consequently, we demonstrate the feasibility and utility of large-scale, low biomass metagenomic analyses using the KatharoSeq protocol. IMPORTANCE Various indoor, outdoor, and host-associated environments contain small quantities of microbial biomass and represent a niche that is often understudied because of technical constraints. Many studies that attempt to evaluate these low-biomass microbiome samples are riddled with erroneous results that are typically false positive signals obtained during the sampling process. We have investigated various low-biomass kits and methods to determine the limit of detection of these pipelines. Here we present KatharoSeq, a high-throughput protocol combining laboratory and bioinformatic methods that can differentiate a true positive signal in samples with as few as 50 to 500 cells. We demonstrate the application of this method in three unique low-biomass environments, including a SAF, a hospital NICU, and an abalone-rearing facility. PMID- 29577087 TI - Fecal Microbiota Transplantation in Gestating Sows and Neonatal Offspring Alters Lifetime Intestinal Microbiota and Growth in Offspring. AB - Previous studies suggest a link between intestinal microbiota and porcine feed efficiency (FE). Therefore, we investigated whether fecal microbiota transplantation (FMT) in sows and/or neonatal offspring, using inocula derived from highly feed-efficient pigs, could improve offspring FE. Pregnant sows were assigned to control or FMT treatments and the subsequent offspring to control treatment, FMT once (at birth), or FMT four times (between birth and weaning). FMT altered sow fecal and colostrum microbiota compositions and resulted in lighter offspring body weight at 70 and 155 days of age when administered to sows and/or offspring. This was accompanied by FMT-associated changes within the offspring's intestinal microbiota, mostly in the ileum. These included transiently higher fecal bacterial diversity and load and numerous compositional differences at the phylum and genus levels (e.g., Spirochaetes and Bacteroidetes at high relative abundances and mostly members of Clostridia, respectively), as well as differences in the abundances of predicted bacterial pathways. In addition, intestinal morphology was negatively impacted, duodenal gene expression altered, and serum protein and cholesterol concentrations reduced due to FMT in sows and/or offspring. Taken together, the results suggest poorer absorptive capacity and intestinal health, most likely explaining the reduced body weight. An additive effect of FMT in sows and offspring also occurred for some parameters. Although these findings have negative implications for the practical use of the FMT regime used here for improving FE in pigs, they nonetheless demonstrate the enormous impact of early-life intestinal microbiota on the host phenotype. IMPORTANCE Here, for the first time, we investigate FMT as a novel strategy to modulate the porcine intestinal microbiota in an attempt to improve FE in pigs. However, reprogramming the maternal and/or offspring microbiome by using fecal transplants derived from highly feed-efficient pigs did not recapitulate the highly efficient phenotype in the offspring and, in fact, had detrimental effects on lifetime growth. Although these findings may not be wholly attributable to microbiota transplantation, as antibiotic and purgative were also part of the regime in sows, similar effects were also seen in offspring, in which these interventions were not used. Nonetheless, additional work is needed to unravel the effects of each component of the FMT regime and to provide additional mechanistic insights. This may lead to the development of an FMT procedure with practical applications for the improvement of FE in pigs, which could in turn improve the profitability of pig production.

AB - Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, emits nitrogen (N) oxide gases (NO, NO2, and N2O), which are potentially hazardous compounds that contribute to global warming. To better understand the dynamics of nitrification-derived N oxide production, we conducted culturing experiments and used an integrative genome-scale, constraint-based approach to model N oxide gas sources and sinks during complete nitrification in an aerobic coculture of two model nitrifying bacteria, the ammonia-oxidizing bacterium Nitrosomonas europaea and the nitrite-oxidizing bacterium Nitrobacter winogradskyi. The model includes biotic genome-scale metabolic models (iFC578 and iFC579) for each nitrifier and abiotic N oxide reactions. Modeling suggested both biotic and abiotic reactions are important sources and sinks of N oxides, particularly under microaerobic conditions predicted to occur in coculture. In particular, integrative modeling suggested that previous models might have underestimated gross NO production during nitrification due to not taking into account its rapid oxidation in both aqueous and gas phases. The integrative model may be found at https://github.com/chaplenf/microBiome-v2.1. IMPORTANCE Modern agriculture is sustained by application of inorganic nitrogen (N) fertilizer in the form of ammonium (NH4+). Up to 60% of NH4+-based fertilizer can be lost through leaching of nitrifier-derived nitrate (NO3-), and through the emission of N oxide gases (i.e., nitric oxide [NO], N dioxide [NO2], and nitrous oxide [N2O] gases), the latter being a potent greenhouse gas. Our approach to modeling of nitrification suggests that both biotic and abiotic mechanisms function as important sources and sinks of N oxides during microaerobic conditions and that previous models might have underestimated gross NO production during nitrification. PMID- 29577089 TI - Mrgprs activation is required for chronic itch conditions in mice. AB - Introduction: Chronic itch has been drawing much attention due to its clinical significance and the complexity of its mechanisms. To facilitate the development of anti-itch strategies, it is necessary to investigate the key players in itch sensation under chronic itch conditions. Several members of the Mrgpr family were identified as itch receptors that detect cutaneous pruritogens in primary sensory neurons. However, the role of Mrgprs in chronic itch conditions has not been well described. Methods: Scratching behaviors of WT and Mrgpr-clusterDelta-/- mice were examined in dry skin model and contact dermatitis model to examine the role of Mrgpr genes in mediating chronic itch sensation. Scratching behaviors of the mice were also examined in allergic itch model. Real-time PCR were performed to examine the expression level of MrgprA3 and MrgprC11 under naive and dry skin conditions. The MrgprA3+ itch-sensing fibers were labeled by tdTomato fluorescence in Mrgpra3GFP-Cre; ROSA26tdTomato mice, and the morphology and density of those fibers in the epidermis were analyzed under dry skin condition. Results: We showed that deleting a cluster of Mrgpr genes in mice reduced scratching behavior severely under two chronic itch conditions, namely dry skin and contact dermatitis, and the allergic itch condition. Moreover, the gene expressions of itch receptors MrgprA3 and MrgprC11 in dorsal root ganglia (DRG) were upregulated significantly under dry skin condition. Consistently, the percentage of MrgprA3+ itch-sensing neurons was increased as well. We also observed hyperinnervation of MrgprA3+ itch-sensing fibers in the epidermis of the skin under dry skin condition. Discussion: We demonstrate that Mrgprs play important roles in mediating chronic itch and allergic itch. These findings enrich our knowledge of itch mechanism and may lead to the development of novel therapeutic approach to combat itch. PMID- 29577090 TI - A Hybrid Neural Network - World Cup Optimization Algorithm for Melanoma Detection. AB - One of the most dangerous cancers in humans is Melanoma. However, early detection of melanoma can help us to cure it completely. This paper presents a new efficient method to detect malignancy in melanoma via images. At first, the extra scales are eliminated by using edge detection and smoothing. Afterwards, the proposed method can be utilized to segment the cancer images. Finally, the extra information is eliminated by morphological operations and used to focus on the area which melanoma boundary potentially exists. To do this, World Cup Optimization algorithm is utilized to optimize an MLP neural Networks (ANN). World Cup Optimization algorithm is a new meta-heuristic algorithm which is recently presented and has a good performance in some optimization problems. WCO is a derivative-free, Meta-Heuristic algorithm, mimicking the world's FIFA competitions. World cup Optimization algorithm is a global search algorithm while gradient-based back propagation method is local search. In this proposed algorithm, multi-layer perceptron network (MLP) employs the problem's constraints and WCO algorithm attempts to minimize the root mean square error. Experimental results show that the proposed method can develop the performance of the standard MLP algorithm significantly. PMID- 29577091 TI - Early Administration of Venovenous Extracorporeal Life Support for Status Asthmaticus during Anaesthetic Induction: Case Report and Literature Review. AB - Here we report a case of a 40-year-old man who visited the emergency room with severe chest pain. He showed a Stanford type B aortic dissection on chest computed tomography. Despite medical treatment and malperfusion of lower extremities, acute renal failure developed; hence thoracic endovascular aortic repair (TEVAR) was considered under general anaesthesia. After endotracheal intubation, ventilation with low tidal volume required high inspiratory airway pressure. An arterial blood gas analysis showed PaCO2 of 61.8mmHg and PaO2 of 26.4mmHg, indicating a status asthmaticus of hypoxaemia and hypercarbia, which did not respond to bronchodilator or mechanical ventilation. Impending cardiac arrest was treated using venovenous extracorporeal life support, which was administered by percutaneous femoral cannulation. Surgical procedure was completed without any complications. Extracorporeal life support was weaned at one day after the operation. The patient was discharged without any complications. PMID- 29577092 TI - Assessment of Maximal Isometric Hand Grip Strength in School-aged Children. AB - Background: Hand grip strength (HGS) test is commonly used as an indicator of overall muscle strength in medical and sport practices. Recently, several studies have proposed that the measurement of the maximal HGS depends on dynamometer's handle position. The aim of the present study was to identify the optimal handle position to obtain maximal HGS using the hand grip dynamometer (HGD) for school aged children. Methods: HGS was assessed with the Jamar digital HGD. Each participant performed three maximum contractions of each hand on three handle positions progressing from first to third position. Results: A total of 135 healthy children aged 5-9 years participated in the study. Participants obtained significantly higher results using position 2 than using positions 1 or 3. The maximal mean (+/- SD) HGS achieved was 9.9 (+/- 3.1) kg with position 1, 10.4 (+/ 3.1) kg with position 2, and 9.0 (+/- 3.2) kg with position 3. Handle position 2 was the most comfortable position for 73% of participants. Conclusions: Our results provide useful methodological information indicating that the second handle position of the Jamar digital HGD is optimal to measure maximal HGS in non athletic healthy pediatric participants aged 5-9 years. PMID- 29577093 TI - Evaluation of a Neurokinin-1 Antagonist in Preventing Multiple-day Cisplatin induced Nausea and Vomiting. AB - Objective: To perform a prospective non-randomized comparison of the effectiveness and safety of combined neurokinin-1 antagonist aprepitant treatment with the standard multiple-day cisplatin regimen for the prevention of cisplatin induced nausea and vomiting (CINV). Methods: Patients being administered 3-day cisplatin-based chemotherapy (25 mg/m2/d) who had never received aprepitant were given either the standard regimen (tropisetron and dexamethasone) or the aprepitant regimen (aprepitant plus tropisetron and dexamethasone). The primary endpoint was the complete response (CR) in the overall phase (OP, 0-120 h) between the combined aprepitant triple regimen group and the standard group. Secondary endpoints were the CR in the acute phase (AP, 0-24 h) and delay phase (DP, 25-120 h) between the two groups. The first time of vomiting was also compared by Kaplan-Meier curves. The impact of CINV on the quality of life was assessed by the Functional Living Index-Emesis (FLIE). Aprepitant-related adverse effects (AEs) were also recorded. Results: A CR was achieved by 80.0% in the aprepitant group compared with 56.0% in the standard group during the OP (P =0.018)as well as during the DP. However, during the AP, the aprepitant and standard therapy groups achieved identical CR rates (98.0%, P =1.000). A longer time to first emesis was documented for the aprepitant group than for the standard group. No effect of CINV on quality of life as assessed by FLIE was reported by 44.7% of aprepitant therapy patients and 24.0% of standard therapy patients (P=0.035). The main aprepitant-related AEs were fatigue and constipation, but there was no significant difference between groups. Conclusion: Combined aprepitant therapy is recommended for the prevention of multiple-day CINV because of its improved CINV control rate and safety. PMID- 29577094 TI - Value of Continuous Video EEG and EEG Responses to Thermesthesia Stimulation in Prognosis Evaluation of Comatose Patients after Cardiopulmonary Resuscitation. AB - Objective: To investigate the clinical value of video-electroencephalography (VEEG) and thermal stimulus on evaluating the prognosis of comatose patients after cardiopulmonary resuscitation. Methods: Twenty eight comatose patients with cardiopulmonary resuscitation were included in the department of ICU of the First Teaching Hospital of Fujian Medical University from February 2013 to March 2016. Of the included 28 patients, 20 cases died (death group) and 8 cases survived (survival group) after cardiopulmonary resuscitation. The VEEG, Glasgow Coma Scale (GCS) and APACHE II score were recorded and compared between the death and survival group. The prediction value of death for VEEG, GCS and APACHE II were evaluated through sensitivity, specificity and area under the receiver operating characteristic (ROC) curve (AUC). Results: GCS and APACHEH II score were statistical different between the death and survival group (P<0.05). With the increase of VEEG grading, the mortality rate of patients increased significantly (P<0.05). Predicting value of mortality for GCS, VEEG and APACHEH II were 57.69%, 61.54% and 71.43% respectively without statistical difference (P>0.05). The death prediction sensitivity and specificity for GCS were 67.0% and 85.0%, for APACHEH II were 95.1% and 85.0%, for VEEG were 100.0% and 85.2%. VEEG has the highest sensitivity, Specificity, coincidence rate and Kappa vale compared to GCS, and APACHEH II. Conclusion: Video-electroencephalography is a useful tool for predicting the death risk for patients who received cardiopulmonary resuscitation. PMID- 29577095 TI - Rapid neuroadaptation to surgically-induced aniseikonia in a 17-year-old patient with high preoperative anisometropia: A case report. AB - Purpose: To report a case of rapid neuroadaptation to surgically-induced aniseikonia in a 17-year-old with preoperative anisometropia of 9.5 D. Observations: A 17-year-old female with a history of retinopathy of prematurity (ROP) and progressive high myopia with resulting anisometropia secondary to conventional laser photocoagulation in her right eye was found to have diplopia after undergoing cataract surgery in that eye. Other etiologies of diplopia were ruled out and reversal of anisometropia remained the only viable diagnosis. Her diplopia fully resolved without intervention within one month of the surgery. Conclusion and Importance: In cases of neuroadaptation to long standing anisometropia, even if that anisometropia develops in infancy, abrupt reversal following surgery can be surprisingly well tolerated. PMID- 29577096 TI - Intravitreal rituximab for the treatment of a secondary intraocular relapse of a large B-cell lymphoma. AB - Purpose: To report a rare case of secondary intraocular lymphoma treated with intravitreal rituximab, following pars plana vitrectomy. Observations: A 74-year old female with history of parotid gland large B-cell lymphoma presented bilateral intraocular recurrence 10 years after the onset of the primary malignancy. Systemic work-up including PET/CT Scan, bone marrow biopsy, brain MRI and CSF analysis were unremarkable, and the patient declined to undergo systemic chemotherapy. Vision loss in her left eye was severe due to significant sub retinal pigment epithelium (RPE) infiltration involving the macula; this eye was treated with external beam radiation therapy. On the right eye, the relapse manifested with vitreous involvement and fovea-sparing multifocal, sub-RPE infiltration for which the patient received monthly intravitreal rituximab injections, following pars plana vitrectomy. Through the course of therapy, the patient achieved good local control and maintained 20/20 visual acuity on her right eye. Brain magnetic resonance imaging (MRI) surveillance, every 3 months, was performed and revealed a cerebellar recurrence 24 months into the course of therapy. Conclusions and importance: Our case illustrates how intravitreal immunotherapy with rituximab may provide local control of CD-20 positive secondary intraocular lymphoma; particularly in cases where systemic therapy is not amenable. In our case, a prior vitrectomy, did not appear to interfere with the therapeutic effect of intravitreal rituximab. Close quarterly surveillance with Brain MRI may help disclose central nervous system recurrences in such cases. PMID- 29577097 TI - Traumatic subhyaloid macular hemorrhage with complete resolution following Neodymium-Doped Yttrium Aluminium Garnet Laser. AB - Purpose: To report a case of traumatic subhyaloid macular hemorrhage with severe sudden vision loss treated successfully with Neodymium-Doped Yttrium Aluminium Garnet Laser (Nd:YAG laser). Observations: A 16-year-old boy presented to the eye clinic with acute vision loss secondary to blunt trauma by a stone to his left eye 3 days prior to consultation that caused subhyaloid macular hemorrhage. Nd:YAG laser was performed to open the hyaloid membrane and allow the blood to diffuse into the vitreous cavity and be absorbed. The patient demonstrated complete recovery as his visual acuity went from counting fingers to 20/20 within 20 days. No complications due to the treatment were reported. Conclusions and importance: To the best of our knowledge, there have been no reported cases of subhyaloid macular hemorrhage treated with Nd:YAG laser in which the etiology was trauma and showed full, rapid recovery with no sequelae. PMID- 29577098 TI - Pericentral hydroxychloroquine retinopathy in a Caucasian female. AB - Purpose: To report a rare presentation of the pericentral pattern of hydroxychloroquine (HCQ) retinal toxicity in a Caucasian female. Observations: The patient presented with 20 years of exposure to HCQ, at a daily dose of 5.2mg/kg of actual body weight, and manifested a pericentral-only phenotype of HCQ toxicity, as demonstrated with detailed structural and functional testing. Conclusions and importance: Although rare, the pericentral pattern of HCQ toxicity may occur in Caucasian patients in the absence of paracentral changes. PMID- 29577099 TI - Bilateral superior rectus transposition and medial rectus recession for bilateral sixth nerve palsy. AB - Purpose: To present the results of bilateral superior rectus transposition with medial rectus recession in a case of chronic bilateral sixth nerve palsy. Observation: Bilateral superior rectus transposition with medial rectus recession resulted in full correction of esotropia with resolution of horizontal diplopia, improvement in abduction, and regain of stereoacuity in our case. There was minimal limitation of adduction, with no abnormal vertical or torsional changes. Conclusion and importance: Bilateral superior rectus transposition with medial rectus recession appears to be a useful procedure for surgical treatment of bilateral sixth nerve palsy with minimal side effects. Given its potential for reduced risk of anterior segment ischemia (ASI), it may have especially good value in the select group of patients at risk for ASI. Studies with larger sample size and longer follow up are needed to further evaluate this procedure and elucidate the variables in surgical technique for superior rectus transposition. PMID- 29577100 TI - Lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to orbital roof: A case report. AB - Purpose: To report a case of lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to the orbital roof. Observations: A 23-year-old female was presented with right lagophthalmos. Five months prior to consult at our clinic, she suffered from a penetrating trauma to the frontal lobe of the brain through the right orbital roof with cerebrospinal fluid leakage. Decompressive craniectomy was performed immediately after the injury using a coronal incision, which was followed by reconstruction with an artificial bone 1 month later. On examination at our clinic, she showed right exposure keratopathy with best corrected visual acuity of 20/100 due to corneal opacity. The palpebral contracted scar was first elongated using Z-plasty technique but excursion of the upper eyelid under a finger force assistance was insufficient to eliminate lagophthalmos. However, complete eyelid closure under a finger force assistance was achieved after sharp dissection of the cicatrized adipose tissue from the orbital roof. An autogenous dermis-fat was grafted on the orbital roof and superior orbital rim to avoid adhesion of orbital adipose tissue onto the bone again. Conclusion and importance: Cicatricial adhesion of an orbital adipose tissue to the orbital roof is one of the possible causes of posttraumatic lagophthalmos in patients with an orbital roof fracture. Surgeons need to be aware of this condition in planning of surgical repair when such a fracture is encountered. PMID- 29577101 TI - Management of recalcitrant polypoidal choroidal vasculopathy by feeder vessel laser photocoagulation. AB - Purpose: To describe management of residual branch vascular network (BVN) in polypoidal choroidal vasculopathy (PCV) by thermal laser photocoagulation of feeder vessel. Observations: Case report of sixty-four year old female with polypoidal choroidal vaculopathy (PCV) with moderate response to seven doses of intravitreal ranibizumab, six doses of intravitreal bevacizumab and one session of photodynamic therapy (PDT). The patient has resolved polyps but persistence of disease activity due to residual BVN and large pigment epithelial detachment (PED). Patient underwent thermal laser photocoagulation of feeder vessel of BVN identified on indocyanine green angiography (ICGA). There was complete resolution of residual BVN and large PED, which was confirmed on ICGA. Conclusions and Importance: Recalcitrant cases of PCV without polyps but having BVN with feeder vessel can be managed by ICGA guided thermal laser photocoagulation. The case report illustrates the importance of utilizing multimodal imaging such as video indocyanine green angiography (ICGA) for identification of feeder vessel and its deployment for optimal management of refractory PCV. PMID- 29577102 TI - A case with corneal perforation due to bacterial concretion derived from lacrimal canaliculitis. AB - Purpose: To report a case with corneal perforation, presumably due to ocular cicatricial pemphigoid (OCP) and bacterial concretion derived from lacrimal canaliculitis. Observations: A patient with OCP demonstrated adherence of concretion to the cornea of her right eye. She also demonstrated canaliculitis in this eye. We removed a whitish precipitate from the bottom of the corneal ulcer. When we flushed her lacrimal pathway, a marked amount of bacterial concretion and dense mucosa were refluxed from both puncta on the right side. On the next day, corneal perforation was visible from the area where concretion was removed. We performed punctoplasty and removed the bacterial concretion from the lacrimal canaliculus and sac. After the operation, her symptoms improved and corneal perforation recovered. Conclusions and Importance: Both lacrimal canaliculitis and OCP can cause corneal perforation, and adherence of bacterial concretion onto the cornea is very rare. However, once it occurs, corneal perforation can rapidly follow. OCP sometimes causes corneal epithelial damage, which may influence adherence to concretion. Canaliculitis in patients with OCP should be managed carefully. PMID- 29577103 TI - Traumatic chiasmal syndrome: A meta-analysis. AB - Purpose: To report a case presenting with bitemporal hemianopia due to traumatic chiasmal syndrome after head injury, and to compare the findings with individual case reports published in the literature. Methods: A detailed search was made in PubMed, MedIND, Taylor and Francis online and Wiley online library databases for individual case reports of traumatic chiasmal syndrome. All the case reports were read in full and the findings summarized in a table, which included details of the case who presented with bitemporal hemianopia as an index case. Results: All published cases of traumatic chiasmal syndrome appear to share some common features, such as injury to the frontal bone and fracture of the anterior skull base. Bitemporal hemianopia and visual acuity have a variable presentation, and do not appear to correlate with severity of injury. Isolated bitemporal hemianopia is rare and clinical improvement may or may not occur. Conclusions and importance: Traumatic chiasmal syndrome should be considered as a differential diagnosis in patients presenting with bitemporal hemianopia after head injury causing frontal and anterior skull base fracture. PMID- 29577104 TI - A new worm infiltrating the human cornea: A report of three cases. AB - Purpose: To characterize a new species of parasitic nematode that triggers uveitis. Observations: Three previously healthy, relatively young people each contracted a corneal stromal nematode that, upon surgical removal and examination, did not match any known nematodes. Clinical ocular findings included corneal opacification, visible corneal worms, conjunctival injection, and uveitis. Conclusions and Importance: The three cases presented here represent a previously undescribed parasitic infection of the cornea by an unidentified nematode. These findings may represent a previously unrecognized zoonotic infection from wildlife sources and potentially a newly documented nematode requiring description. Future clinical findings regarding this newly described nematode are needed to further develop our understanding of the disease. PMID- 29577105 TI - Immune responses to engineered nanomaterials: current understanding and challenges. AB - Engineered nanomaterials (ENM) are utilized in many applications due to their unique physicochemical properties. The increasing use of ENMs in consumer products raises concerns of potential adverse effects in humans and the environment. A common outcome of exposure (intentional, environmental or occupational) to ENMs is altered immune responses including inflammation, hypersensitivity, and immunosuppression. ENMs have been shown to interact with the immune system through key effector cells (i.e. mast cells and antigen presenting cells) or via complement activation leading to consequences to both innate and adaptive immunity. Further, upon introduction into a biological system, ENMs are rapidly coated with proteins, lipids and other macromolecules forming a biocorona which impacts immune cell and complement responses. In this current opinion, we highlight key studies and challenges in understanding cellular mechanisms of ENM-mediated immunomodulation and toxicity. PMID- 29577106 TI - Modeling Bloch oscillations in nanoscale Josephson junctions. AB - Bloch oscillations in nanoscale Josephson junctions with a Coulomb charging energy comparable to the Josephson coupling energy are explored within the context of a model previously considered by Geigenmuller and Schon that includes Zener tunneling and treats quasiparticle tunneling as an explicit shot-noise process. The dynamics of the junction quasicharge are investigated numerically using both Monte Carlo and ensemble approaches to calculate voltage-current characteristics in the presence of microwaves. We examine in detail the origin of harmonic and subharmonic Bloch steps at dc biases I = (n/m)2ef induced by microwaves of frequency f and consider the optimum parameters for the observation of harmonic (m = 1) steps. We also demonstrate that the GS model allows a detailed semiquantitative fit to experimental voltage-current characteristics previously obtained at the Chalmers University of Technology, confirming and strengthening the interpretation of the observed microwave-induced steps in terms of Bloch oscillations. PMID- 29577107 TI - Vitamin D Supplementation in Patients With Type 2 Diabetes: The Vitamin D for Established Type 2 Diabetes (DDM2) Study. AB - Context: Observational data support a role for vitamin D in type 2 diabetes, but evidence from trials is inconclusive. Objective: To evaluate the effect of vitamin D supplementation on beta-cell function and hemoglobin A1c (HbA1c) in patients with well-controlled type 2 diabetes. Design: Double-blind, randomized, placebo-controlled clinical trial. Setting: Tufts Medical Center, Boston, MA; VA Medical Center, Cincinnati, OH. Participants: A total of 127 patients (mean age, 60 years) with stable (HbA1c <=7.5%) diabetes managed with lifestyle only or lifestyle plus metformin. Intervention: Subjects were given 4000 units of vitamin D3 (cholecalciferol) daily or placebo for 48 weeks. Main Outcome Measure: Insulin secretion rate (ISR) was estimated from peripheral plasma C-peptide levels after a 3-hour 75-g oral glucose tolerance test done at baseline and week 24. Changes in HbA1c were assessed at 16, 24, 36, and 48 weeks. Results: Baseline mean plasma 25-hydroxyvitamin D [25(OH)D] concentration was 26.6 ng/mL, mean HbA1c was 6.6%, and 78% of patients were on metformin. At week 24, mean 25(OH)D changed by 20.5 and -1.6 ng/mL in the vitamin D and placebo groups, respectively (P < 0.001). The vitamin D and placebo groups did not differ in change in ISR or HbA1c. Among patients treated with lifestyle only (n = 28), vitamin D supplementation reduced HbA1c compared with placebo (-0.1% vs 0.3%, respectively; P = 0.034) at week 24. This result was not observed at the other time points and could be due to chance. Conclusion: Vitamin D3 at 4000 IU/d did not change ISR or HbA1c in patients with well-controlled type 2 diabetes on metformin not selected for vitamin D deficiency. PMID- 29577108 TI - Testosterone and All-Cause Mortality in Older Men: The Role of Metabolic Syndrome. AB - Previous studies have shown controversial results about the role of testosterone in all-cause mortality in elderly men. We hypothesized that metabolic syndrome (MetS) could partly explain this discrepancy. We therefore examined the association of all-cause mortality with total and bioavailable testosterone, taking into account the MetS. We used data from the Three-City Cohort (3C) study with 12-year follow-up. The 3C study included 3650 men aged >65 years in three French cities. Hormone was measured in a random subsample of 444 men, and MetS was determined as stated by the International Diabetes Federation criteria. We used inverse-probability-weighted Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs). Of 444 men included in the analysis, 106 (23.9%) had MetS at baseline, and 166 died over the follow-up. There was a significant interaction between testosterone level and MetS for all-cause mortality (P = 0.002 and P = 0.008 for total and bioavailable testosterone, respectively). Among men with MetS, a decrease in one standard deviation of testosterone was associated with higher mortality risk [HR 1.78 (95% CI 1.13 to 2.78) and HR 1.83 (95% CI 1.17 to 2.86) for total and bioavailable testosterone, respectively]. By contrast, there was no association of testosterone with mortality risk among men without MetS. Our results suggest that MetS modifies the association between testosterone and mortality in older men. If confirmed, these findings could contribute to improve risk stratification and better manage the health of older men.

AB - Nod-like receptor (NLR)X1 is an NLR family protein that localizes to the mitochondrial matrix and modulates reactive oxygen species production, possibly by directly interacting with the electron transport chain. Recent work demonstrated that cells lacking NLRX1 have higher oxygen consumption but lower levels of adenosine triphosphate, suggesting that NLRX1 might prevent uncoupling of oxidative phosphorylation. We therefore hypothesized that NLRX1 might regulate whole-body energy metabolism through its effect on mitochondria. Male NLRX1 whole body knockout (KO) mice and wild-type (WT) C57BL/6N controls were fed a low-fat or a high-fat (HF) diet for 16 weeks from weaning. Contrary to this hypothesis, there were no differences in body weight, adiposity, energy intake, or energy expenditure between HF-fed KO and WT mice, but instead HF KO mice were partially protected from the development of diet-induced hyperglycemia. Additionally, HF KO mice did not present with hyperinsulinemia during the glucose tolerance test, as did HF WT mice. There were no genotype differences in insulin tolerance, which led us to consider a pancreatic phenotype. Histology revealed that KO mice were protected from HF-induced pancreatic lipid accumulation, suggesting a potential role for NLRX1 in pancreatic dysfunction during the development diet-induced type 2 diabetes mellitus. Hence, NLRX1 depletion partially protects against postabsorptive hyperglycemia in obesity that may be linked to the prevention of pancreatic lipid accumulation. Although the actual mechanisms restoring glucose and insulin dynamics remain unknown, NLRX1 emerges as a potentially interesting target to inhibit for the prevention of type 2 diabetes mellitus. PMID- 29577110 TI - Health and Cardiometabolic Disease in Transgender Adults in the United States: Behavioral Risk Factor Surveillance System 2015. AB - Context: Little is known about the health of transgender adults in the United States, a growing population. There have been no large reports examining differences in health status and cardiometabolic disease in subgroups of transgender adults [female-to-male (FTM), male-to-female (MTF), and gender nonconforming (GNC)] in the United States. Objective: Compare the health status and prevalence of cardiometabolic disease among specific subgroups of transgender adults (FTM, MTF, GNC) with those of cisgender adults in the United States. Design: Secondary data analysis based on the 2015 Behavioral Risk Factor Surveillance System survey. Setting: The 22 states in the United States that asked about transgender identity. Participants: Noninstitutionalized adults age >=18 years who reside in the United States, identified through telephone-based methods. Main Outcome Measures: Data were extracted for respondents who answered the transgender identity question. Weighted percentages are given for all measures. Adjusted odds ratios (ORs) are reported for health status and cardiometabolic disease measures. Results: FTM adults have a higher odds of being uninsured than both cisgender women [OR 3.8; 95% confidence interval (CI), 2.1 to 7.1] and cisgender men (OR 2.5; 95% CI, 1.4 to 4.7). MTF adults have a higher odds of reporting myocardial infarction than cisgender women (OR 2.9; 95% CI, 1.6 to 5.3) but not cisgender men. Conclusions: There are significant differences in health status measures and cardiometabolic health between subgroups of transgender adults and cisgender adults. There is a need for additional research to understand the societal and medical (e.g., hormone therapy) effects on these outcomes. PMID- 29577111 TI - Phosphorus Balance in Adolescent Girls and the Effect of Supplemental Dietary Calcium. AB - There are limited data on phosphorus balance and the effect of dietary calcium supplements on phosphorus balance in adolescents. The purpose of this study was to determine phosphorus balance and the effect of increasing dietary calcium intake with a supplement on net phosphorus absorption and balance in healthy adolescent girls. This study utilized stored urine, fecal, and diet samples from a previously conducted study that focused on calcium balance. Eleven healthy girls ages 11 to 14 years participated in a randomized crossover study, which consisted of two 3-week periods of a controlled diet with low (817 +/- 19.5 mg/d) or high (1418 +/- 11.1 mg/d) calcium, separated by a 1-week washout period. Phosphorus intake was controlled at the same level during both placebo and calcium supplementation (1435 +/- 23.5 and 1453 +/- 28.0 mg/d, respectively, p = 0.611). Mean phosphorus balance was positive by about 200 mg/d and was unaffected by the calcium supplement (p = 0.826). Urinary phosphorus excretion was lower with the calcium supplement (535 +/- 42 versus 649 +/- 41 mg/d, p = 0.013), but fecal phosphorus and net phosphorus absorption were not significantly different between placebo and calcium supplement (553 +/- 60 versus 678 +/- 63 versus mg/d, p = 0.143; 876 +/- 62 versus 774 +/- 64 mg/d, p = 0.231, respectively). Dietary phosphorus underestimates using a nutrient database compared with the content measured chemically from meal composites by ~40%. These results show that phosphorus balance is positive in girls during adolescent growth and that a calcium dietary supplement to near the current recommended level does not affect phosphorus balance when phosphorus intake is at 1400 mg/d, a typical US intake level.

AB - This study explores the perspectives of business college graduates, how technology has shaped the structures of their jobs, and the role of non-technical skills as they navigate the changing career path. Three overlapping themes emerged from the data analysis: (1) influence of increased technology capabilities on job structures and careers; (2) participation in job-related training and formal education as means of adapting to the new work environment; and (3) the role of non-technical skills in the workplace amidst the intensification of technology change. This research provides higher education practitioners and labor market researchers qualitative perspectives on work structure changes. PMID- 29577113 TI - STAT1 Is Required for Suppression of Type 17 Immunity during Influenza and Bacterial Superinfection. AB - Influenza is an annual, global health care concern. Secondary bacterial pneumonia is a severe complication associated with primary influenza virus infection, often resulting in critical morbidity and mortality. Our laboratory has identified influenza-induced suppression of anti-bacterial Type 17 immunity as a mechanism for enhanced susceptibility to bacterial super-infection. We have shown that influenza-induced type I interferon impairs Type 17 activation. STAT1 is a transcription factor involved in interferon signaling, shared by type I, II, and III interferon. In this work, we investigated the role of STAT1 signaling during influenza, methicillin-resistant Staphylococcus aureus (MRSA) super-infection. STAT1-/- mice had increased morbidity and airway inflammation compared to control mice during influenza mono-infection. Despite this worsened anti-viral response, STAT1-/- mice were protected from super-infection bacterial burden and mortality compared to controls. Type 17 immune activation was increased in lymphocytes in STAT1-/- mice during super-infection. The elevation in Type 17 immunity was not related to increased IL-23 production, as type I interferon could inhibit IL-23 expression in a STAT1 independent manner. STAT1-/- antigen presenting cells were inherently biased towards Type 17 polarization compared to control cells. Further, STAT1-/- dendritic cells produced attenuated IL-6 and TNFalpha upon heat killed S. aureus stimulation compared to control. Overall, these data indicate that STAT1 signaling plays a detrimental role in influenza, MRSA super-infection by controlling the magnitude of Type 17 immune activation. PMID- 29577114 TI - Patterns of Statin Use in Older Medicare Beneficiaries With Traumatic Brain Injury. AB - Background: In addition to lowering lipids, statins also may be beneficial for older adults sustaining a traumatic brain injury (TBI), as statin use prior to and following trauma may decrease mortality following injury. However, despite statins' potential to reduce mortality, there is limited research regarding statin use among older adults. Objective: To characterize and investigate factors associated with statin use among older adults with TBI. Methods: A retrospective drug utilization study was used to characterize statin use among Medicare beneficiaries 65 and older hospitalized with a TBI during 2006 to 2010 and with continuous Medicare Parts A, B, and D coverage 6 months prior and 12 months following TBI. Logistic regression was used to investigate the factors associated with statin use. The exposure of interest was statin use prior to and following TBI. Results: Of the 75 698 beneficiaries included in the study, 37 874 (~50%) of beneficiaries used a statin at least once during the study period. The most common statin used was simvastatin, while fluvastatin was the least used statin. Statin users were more likely to have cardiovascular diseases when compared to nonusers. Hyperlipidemia was a major factor associated with statin use and had the greatest impact on statin use compared to nonuse (odds ratio = 9.54; 95% confidence interval = 9.07, 10.03). Conclusions: This national sample of older adults with TBI suggests that statins are commonly used. Future studies must next examine the impact of statin use on mortality and secondary injury in order to shape pharmacological therapy guidelines following TBI. PMID- 29577115 TI - Neighborhood Matching for Curved Domains with Application to Denoising in Diffusion MRI. AB - In this paper, we introduce a strategy for performing neighborhood matching on general non-Euclidean and non-flat domains. Essentially, this involves representing the domain as a graph and then extending the concept of convolution from regular grids to graphs. Acknowledging the fact that convolutions are features of local neighborhoods, neighborhood matching is carried out using the outcome of multiple convolutions at multiple scales. All these concepts are encapsulated in a sound mathematical framework, called graph framelet transforms (GFTs), which allows signals residing on non-flat domains to be decomposed according to multiple frequency subbands for rich characterization of signal patterns. We apply GFTs to the problem of denoising of diffusion MRI data, which can reside on domains defined in very different ways, such as on a shell, on multiple shells, or on a Cartesian grid. Our non-local formulation of the problem allows information of diffusion signal profiles of drastically different orientations to be borrowed for effective denoising. PMID- 29577116 TI - Probing the swelling-dependent mechanical and transport properties of polyacrylamide hydrogels through AFM-based dynamic nanoindentation. AB - Hydrogels are composed of a crosslinked polymer network and water. The constitutive behaviors of hydrogels have been modeled based on Flory-Huggins theory. Within this model, the thermodynamic and kinetic parameters are assumed to be of constant values and are typically characterized through swelling tests. Since most hydrogels can absorb a large amount of solvent from the dry state to the swollen state, and the network size and solvent concentration of the hydrogels change significantly, the assumption of constant values of the thermodynamic and kinetic properties as the network swells is questionable. In this work, we have experimentally shown that even for the simple neutral polyacrylamide (PAAm) hydrogels, their mechanical responses cannot be fully described by the Flory-Huggins theory with constant thermodynamic parameters: N (number of chains per unit volume of dry polymers) and chi (polymer-solvent interaction parameter). For a more complete and precise characterization of the hydrogels, we measure the evolving properties of the gels as the network swells. Here, we use dynamic indentation to measure the poroelastic properties (shear modulus G, Poisson's ratio nu and diffusivity D) of the hydrogels under a wide range of swelling ratios. We also use linear perturbation to build the link between G, nu and N, chi, and plot the thermodynamic parameters in the Flory Huggins theory as a function of the hydrogel swelling ratio. Consequently, the validity of the hydrogel models based on Flory-Huggins theory can be quantitatively examined. PMID- 29577117 TI - Modulation of whey protein-kappa carrageenan hydrogel properties via enzymatic protein modification. AB - Treatment of whey protein isolate (WPI; 1 to 25% w/w) in heated kappa-carrageenan (KC; 2% w/w) slurries with protease and/or transglutaminase modulated the properties of the hydrogels formed after cooling. Observation of peak compression stress and strain at gel rupture showed WPI incorporation at 1, 5 and 10% (w/w) significantly reduced the strength and deformability of 2% (w/w) KC gels. Treatment of WPI solutions in KC slurries with Alcalase 2.4L was shown by both SDS-Page and size exclusion HPLC to reduce protein/peptide molecular weight distributions below 10 kDa, with large portions below 1 kDa. This peptide size reduction within the KC matrix produced more translucent gels with a more organized wall and cell structure as observed by SEM, which resulted in gels with observed rupture stress/strain levels similar to 2% KC alone. Transglutaminase treatment of WPI-KC slurries showed the reverse behavior, reducing gel translucency, strength and deformability. At these loadings, WPI-KC gel strength/deformability appears to relate decreasing peptide size to gel behavior trending towards KC-only gels; suggesting peptide size modulation in protein carbohydrate complexes will allow significant tailoring of texture for the delivery of protein/peptide rich gelled products.

AB - A novel nanohybrid catalyst was developed by assembling copper ferrite nanoparticles on carbon nanotubes. The supramolecular catalyst was applied to the one-pot azidation/1,3-dipolar cycloaddition of various substrates, at room temperature, and in an aqueous medium. The nanohybrid could also be recycled and reused by means of magnetic recovery. PMID- 29577119 TI - Apoptosis effects of imperatorin on synoviocytes in rheumatoid arthritis through mitochondrial/caspase-mediated pathways. AB - Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease associated with a potential imbalance between the growth and death of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLSs). Imperatorin (IPT) is a naturally occurring furanocoumarin found in umbelliferous vegetables, citrus fruits, and some herbs. The effects of IPT on the proliferation and apoptosis of RA-FLSs and its potential underlying mechanisms have remained unclear. RA-FLSs obtained from RA patients were induced by interleukin-1beta (IL-1beta) and treated with IPT. Cell viability was determined by MTT assay. Apoptotic cell death was analyzed by Annexin V-FITC/PI double staining and Hoechst 33342 staining. The loss in the mitochondrial membrane potential (DeltaPsim) was visualized on the basis of JC-1 staining via fluorescence microscopy, and protein expression changes were assessed by western blot, whereas in vivo studies were conducted in male Wistar rats followed by histopathological assessment via TUNEL assay and HE staining of tissues. The results showed that IPT significantly reduced cell viability, accelerated cell apoptosis and decreased matrix metalloproteinases-1/-3 expression in IL-1beta-induced RA-FLSs. Furthermore, IPT exposure was found to disrupt the DeltaPsim compared to the IL-1beta-induced treatment. Moreover, IPT increased the release of mitochondrial cytochrome C, the ratio of Bax/Bcl-2, and the cleavage of caspase-9, caspase-3 and poly (ADP-ribose) polymerase. In vivo studies showed that IPT not only significantly reduced the collagen induced arthritis by reducing synovial hyperplasia, and pannus formation but also enhanced the apoptotic index of ankle joint cells. Conclusively, our findings suggest that IPT inhibits cell proliferation and induces apoptosis in RA-FLSs that may be associated with mitochondrial/caspase-mediated signalling pathways. PMID- 29577120 TI - In vitro and environmental toxicity of reduced graphene oxide as an additive in automotive lubricants. AB - Despite the ground-breaking potential of nanomaterials, their safe and sustainable incorporation into an array of industrial markets prompts a deep and clear understanding of their potential toxicity for both humans and the environment. Among the many materials with great potential, graphene has shown promise in a variety of applications; however, the impact of graphene based products on living systems remains poorly understood. In this paper, we illustrate that via exploiting the tribological properties of graphene nanosheets, we can successfully improve both the frictional behaviour and the anti-wear capacity of lubricant oil for mechanical transmission. By virtue of reducing friction and enhancing lubricant lifetimes, we can forecast a reduction in friction based energy loss, in addition to a decrease in the carbon footprint of vehicles. The aforementioned positive environmental impact is further strengthened considering the lack of acute toxicity found in our extensive in vitro investigation, in which both eukaryotic and prokaryotic cells were tested. Collectively, our body of work suggests that by the use of safe nanoadditives we could contribute to reducing the environmental impact of transportation and therein take a positive step towards a more sustainable automotive sector. The workflow proposed here for the evaluation of human and environmental toxicity will allow for the study of nanosized bare graphene material and can be broadly applied to the translation of graphene-based nanomaterials into the market. PMID- 29577121 TI - Evaluation of the nutrition and function of cow and goat milk based on intestinal microbiota by metagenomic analysis. AB - Milk contains nutrients needed by the body, and the main components of different animal milk vary. Accordingly, we evaluated cow and goat milk's nutrition and their effects on the gut microbiota in mice models using a high-throughput 16S rRNA sequencing technology. The intestinal microbiota of mice changed significantly after the intake of cow and goat milk, and the goat milk had a greater effect on the intestinal microbial community than the cow milk. Bifidobacterium, Allobaculum, Olsenella and Akkermansia grew significantly in both cow and goat milk groups compared with the control group, indicating that milk positively affected their growth. We also found that the citrate cycle (TCA cycle), pyruvate metabolism, and amino sugar and nucleotide sugar metabolism, as well as lipoic acid metabolism, were higher in the goat milk group than in the cow milk group. Association analysis of milk components and their representative intestinal microbiota showed that casein, alphas1-casein, and beta + kappa-casein were positively correlated with Enterococcus and Allobaculum, and negatively correlated with Roseburia. Protein and alphas2-casein were positively associated with Akkermansia, Bifidobacterium and Eubacterium. PMID- 29577122 TI - CO oxidation activity of Pt, Zn and ZnPt nanocatalysts: a comparative study by in situ near-ambient pressure X-ray photoelectron spectroscopy. AB - The investigation of nanocatalysts under ambient pressure by X-ray photoelectron spectroscopy gives access to a wealth of information on their chemical state under reaction conditions. Considering the paradigmatic CO oxidation reaction, a strong synergistic effect on CO catalytic oxidation was recently observed on a partly dewetted ZnO(0001)/Pt(111) single crystal surface. In order to bridge the material gap, we have examined whether this inverse metal/oxide catalytic effect could be transposed on supported ZnPt nanocatalysts deposited on rutile TiO2(110). Synchrotron radiation near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) operated at 1 mbar of O2 : CO mixture (4 : 1) was used at a temperature range between room temperature and 450 K. To tackle the complexity of the problem, we have also studied the catalytic activity of nanoparticles (NPs) of the same size, consisting of pure Pt and Zn nanoparticles (NPs), for which, moreover, NAP-XPS studies are a novelty. The comparative approach shows that the CO oxidation process is markedly different for the pure Pt and pure Zn NPs. For pure Pt NPs, CO poisoned the metallic surfaces at low temperature at the onset of CO2 evolution. In contrast, the pure Zn NPs first oxidize into ZnO, and trap carbonates at low temperature. Then they start to release CO2 in the gas phase, at a critical temperature, while continuously producing it. The pure Zn NPs are also immune to support encapsulation. The bimetallic nanoparticle borrows some of its characteristics from its two parent metals. In fact, the ZnPt NP, although produced by the sequential deposition of platinum and zinc, is platinum terminated below the temperature onset of CO oxidation and poisoned by CO. Above the CO oxidation onset, the nanoparticle becomes Zn-rich with a ZnO shell. Pure Pt and ZnPt NPs present a very similar activity towards CO oxidation, in contrast with what is reported in a single crystal study. The present study demonstrates the effectiveness of NAP-XPS in the study of complex catalytic processes at work on nanocatalysts under near-ambient pressures, and highlights once more the difficulty of transposing single crystal surface observations to the case of nanoobjects. PMID- 29577123 TI - Recent advances in functionalized micro and mesoporous carbon materials: synthesis and applications. AB - Functionalized nanoporous carbon materials have attracted the colossal interest of the materials science fraternity owing to their intriguing physical and chemical properties including a well-ordered porous structure, exemplary high specific surface areas, electronic and ionic conductivity, excellent accessibility to active sites, and enhanced mass transport and diffusion. These properties make them a special and unique choice for various applications in divergent fields such as energy storage batteries, supercapacitors, energy conversion fuel cells, adsorption/separation of bulky molecules, heterogeneous catalysts, catalyst supports, photocatalysis, carbon capture, gas storage, biomolecule detection, vapour sensing and drug delivery. Because of the anisotropic and synergistic effects arising from the heteroatom doping at the nanoscale, these novel materials show high potential especially in electrochemical applications such as batteries, supercapacitors and electrocatalysts for fuel cell applications and water electrolysis. In order to gain the optimal benefit, it is necessary to implement tailor made functionalities in the porous carbon surfaces as well as in the carbon skeleton through the comprehensive experimentation. These most appealing nanoporous carbon materials can be synthesized through the carbonization of high carbon containing molecular precursors by using soft or hard templating or non-templating pathways. This review encompasses the approaches and the wide range of methodologies that have been employed over the last five years in the preparation and functionalisation of nanoporous carbon materials via incorporation of metals, non metal heteroatoms, multiple heteroatoms, and various surface functional groups that mostly dictate their place in a wide range of practical applications. PMID- 29577124 TI - First characterization of a biphasic, switch-like DNA amplification. AB - We report the first DNA amplification chemistry with switch-like characteristics: the chemistry is biphasic, with an expected initial phase followed by an unprecedented high gain burst of product oligonucleotide in a second phase. The first and second phases are separated by a temporary plateau, with the second phase producing 10 to 100 times more product than the first. The reaction is initiated when an oligonucleotide binds and opens a palindromic looped DNA template with two binding domains. Upon loop opening, the oligonucleotide trigger is rapidly amplified through cyclic extension and nicking of the bound trigger. Loop opening and DNA association drive the amplification reaction, such that reaction acceleration in the second phase is correlated with DNA association thermodynamics. Without a palindromic sequence, the chemistry resembles the exponential amplification reaction (EXPAR). EXPAR terminates at the initial plateau, revealing a previously unknown phenomenon that causes early reaction cessation in this popular oligonucleotide amplification reaction. Here we present two distinct types of this biphasic reaction chemistry and propose dominant reaction pathways for each type based on thermodynamic arguments. These reactions create an endogenous switch-like output that reacts to approximately 1 pM oligonucleotide trigger. The chemistry is isothermal and can be adapted to respond to a broad range of input target molecules such as proteins, genomic bacterial DNA, viral DNA, and microRNA. This rapid DNA amplification reaction could potentially impact a variety of disciplines such as synthetic biology, biosensors, DNA computing, and clinical diagnostics.

PMID- 29577127 TI - White zein colloidal particles: synthesis and characterization of their optical properties on the single particle level and in concentrated suspensions. AB - Growing interest in using natural, biodegradable ingredients for food products leads to an increase in research for alternative sources of functional ingredients. One alternative is zein, a water-insoluble protein from corn. Here, a method to investigate the optical properties of white zein colloidal particles is presented in both diluted and concentrated suspensions. The particles are synthesized, after purification of zein, by anti-solvent precipitation. Mean particle diameters ranged from 35 to 135 nm based on dynamic light scattering. The value of these particles as white colorant is examined by measuring their optical properties. Dilute suspensions are prepared to measure the extinction cross section of individual particles and this was combined with Mie theory to determine a refractive index (RI) of 1.49 +/- 0.01 for zein particles dispersed in water. This value is used to further model the optical properties of concentrated suspensions. To obtain full opacity of the suspension, comparable to 0.1-0.2 wt% suspensions of TiO2, concentrations of 2 to 3.3 wt% of zein particles are sufficient. The optimal size for maximal scattering efficiency is explored by modeling dilute and concentrated samples with RI's matching those of zein and TiO2 particles in water. The transport mean free path of light was determined experimentally and theoretically and the agreement between the transport mean free path calculated from the model and the measured value is better than 30%. Such particles have the potential to be an all-natural edible alternative for TiO2 as white colorant in wet food products. PMID- 29577128 TI - A high-response transparent heater based on a CuS nanosheet film with superior mechanical flexibility and chemical stability. AB - Transparent heaters are widely used in technologies such as window defrosting/defogging, displays, gas sensing, and medical equipment. Apart from mechanical robustness and electrical and optical reliabilities, outstanding chemical stability is also critical to the application of transparent heaters. In this regard, we first present a highly flexible and large-area CuS transparent heater fabricated by a colloidal crackle pattern method with an optimized sheet resistance (Rs) as low as 21.5 Omega sq-1 at a ~80% transmittance. The CuS transparent heater exhibits remarkable mechanical robustness during bending tests as well as high chemical stability against acid and alkali environments. In the application as a transparent heater, the CuS heater demonstrates a high thermal resistance of 197 degrees C W-1 cm2 with a fast switching time (<30 s), requiring low input voltages (<4.5 V) to achieve uniform temperatures of ~110 degrees C across large areas. The temperature of the wearable CuS heater, which is stuck on the skin, can be real-time controlled through a Bluetooth device in a cell phone wirelessly. Based on the wireless control system, we demonstrated an application of the CuS heater in snow removal for solar panels. These CuS network TCEs with high flexibility, transparency, conductivity, and chemical stability could be widely used in wearable electronic products.

PMID- 29577130 TI - Static and dynamic properties of a semiflexible polymer in a crowded environment with randomly distributed immobile nanoparticles. AB - Molecular dynamic simulations are performed for semiflexible polymers in a crowded environment with randomly distributed immobile nanoparticles (NPs). Herein, the effects of chain stiffness (ktheta), polymer-NP interaction (epsilonPN), and concentration of NPs (CNP) on the static and dynamic properties of the polymers have been studied. The mean square radius of gyration RG2 can be increased, decreased, or unchanged depending on these three variables. For a fully flexible polymer (ktheta = 0), RG2 changes non-monotonously with epsilonPN and CNP. However, for a semiflexible polymer (ktheta = 10 with its persistence length larger than the inter-particle distance of the NPs), RG2 decreases monotonously or remains unchanged with an increase in epsilonPN or CNP; this indicates the softening of polymer by the NPs. Moreover, the translational diffusion and rotation of the polymer are retarded by the NPs. Subdiffusion is observed for both the fully flexible polymer and semiflexible polymer at a sufficiently large epsilonPN. The effect of NPs on the translational diffusion is more obvious for the fully flexible polymer because more monomers are in contact with the NPs in the fully flexible polymer. In contrast, the effect of NPs on rotation is more obvious for the semiflexible polymer because it is in contact with more NPs. Furthermore, the rotational relaxation time tauR of the semiflexible polymer increases faster with an increase in epsilonPN or CNP than that of the fully flexible polymer. PMID- 29577131 TI - Bright monolayer tungsten disulfide via exciton and trion chemical modulations. AB - Atomically thin transition metal dichalcogenides (TMDCs) with exceptional electrical and optical properties have drawn tremendous attention for use in novel optoelectronic applications as photodetectors, transistors, light emitters, etc. However, electron bound trions formed through the combination of neutral excitons and electrons significantly decrease the photoluminescence (PL) efficiency of TMDCs. In this study, we report a simple yet efficient chemical doping strategy to modulate the optical properties of monolayer tungsten disulfide (WS2). As a demonstrative example, a chemically doped monolayer of WS2 exhibits remarkable PL enhancement of about one order of magnitude higher than that of pristine WS2. This outstanding PL enhancement is attributed to the fact that excess electrons, which promote the formation of electron-bound trions, are reduced in number through charge transfer from WS2 to the chemical dopant. Furthermore, an improved degree of circular polarization from ~9.0% to ~41.5% was also observed in the chemically doped WS2 monolayer. This work describes a feasible strategy to manipulate the optical properties of TMDCs via exciton modulation, making TMDCs promising candidates for versatile semiconductor-based photonic devices. PMID- 29577132 TI - Full-color capable light-emitting diodes based on solution-processed quantum dot layer stacking. AB - To date, most of the studies on quantum dot-light-emitting diodes (QLEDs) have been dedicated to the fabrication of high-efficiency monochromatic devices. However, for the ultimate application of QLEDs to the next-generation display devices, QLEDs should possess a full-color emissivity. In this study, we report the fabrication of all-solution-processed full-color-capable white QLEDs with a standard device architecture, where sequentially stacked blue (B)/green (G)/red (R) quantum dot (QD)-emitting layers (EMLs) are sandwiched by poly(9 vinylcarbazole) as the hole transport layer and ZnO nanoparticles (NPs) as the electron transport layer. To produce interlayer mixing-free, well-defined B/G/R QD layering assemblies via successive spin casting, an ultrathin ZnO NP buffer is inserted between different-colored QD layers. The present full-color-capable white QLED exhibits high device performance with the maximum values of 16 241 cd m-2 for luminance and 6.8% for external quantum efficiency. The promising results indicate that our novel EML design of ZnO NP buffer-mediated QD layer stacking may afford a viable means towards bright, efficient full-color-capable white devices. PMID- 29577133 TI - Cross dehydrogenative coupling of sugar enol ethers with terminal alkenes in the synthesis of pseudo-disaccharides, chiral oxadecalins and a conjugated triene. AB - An efficient strategy for the synthesis of C-2 and C-3 branched sugar dienes via cross dehydrogenative coupling of sugar enol ethers with terminal alkenes was developed. Both pyran and furan based enol ethers coupled smoothly with electron rich as well as deficient alkene sources yielding sugar dienes with complete E stereoselectivity. This coupling reaction was applied successfully for the synthesis of orthogonally protected pseudo-C-saccharides as an alternative to olefin metathesis. Substrate scope was further enhanced by reacting exoglycals with methyl acrylate to generate C-5 branched sugars with moderate diastereoselectivity. These diene subunits were reacted with maleic anhydride under [4 + 2] cycloaddition conditions to generate highly functionalised chiral oxadecalin cores. Finally, utilizing this C-C bond formation, a sugar based conjugated triene was synthesized in excellent yield and selectivity.

AB - An effective dehydrochlorination of bis(phenylsulfonyl)alkane to prepare alkene building blocks is developed.

AB - Optimized catalysts show great potential for renewable energy storage and conversion. Herein, we report metallic CuCo2S4 nanosheets (NSs) of atomic thickness as efficient bifunctional electrocatalysts for use in portable, flexible Zn-air batteries. The metallic CuCo2S4 NSs of atomic thickness with 4 atom-thick to 6-atom-thick layers are confirmed by temperature-dependent electrical resistance measurements and atomic force microscopy. Furthermore, extended X-ray absorption fine structure spectroscopy confirms that CuCo2S4 NSs with sulfur vacancies can further increase the OER activity. Due to high electrical conductivity and ultrathin nanosheet structure with abundant defects, CuCo2S4 NSs exhibit excellent reversible oxygen catalytic performance with an overpotential of 287 mV (at j = 10 mA cm-2) for the oxygen evolution reaction (OER) and an onset potential of 0.90 V for the oxygen reduction reaction (ORR). Additionally, the portable, flexible Zn-air battery using CuCo2S4 NSs as the air cathode displays a high open circuit voltage and strong rechargeable capacity for 18 h. The present study highlights the importance of designing metallic catalysts having atomic thickness with surface defects for highly efficient and stable renewable energy storage and conversion.

These binary ions, Aun+Hem, were produced by electron ionization of helium nanodroplets doped with neutral gold clusters and were detected using mass spectrometry. For a given value of n, the distribution of ions as a function of the number of added helium atoms, m, has been recorded. Peaks with anomalously high intensities, corresponding to so-called magic number ions, are identified and interpreted in terms of the geometric structures of the underlying Aun+ ions. These features can be accounted for by planar structures for Aun+ ions with n <= 7, with the addition of helium having no significant effect on the structures of the underlying gold cluster ions. According to ion mobility studies and some theoretical predictions, a 3-D structure is expected for Au8+. However, the findings for Au8+ in this work are more consistent with a planar structure.

AB - A fast and efficient route for the introduction of a methylene bridged-amine (morpholinomethyl) functionality in the C5 position of the sulfonylated cytosine nucleobase has been developed. First, novel N1-sulfonylcytosine derivatives 3-6 were prepared by the condensation of silylated cytosine with selected sulfonyl chlorides. They were subsequently transformed to 5-morpholinomethyl-N1 sulfonylcytosine derivatives (8, 12-15) using microwave irradiation. As a result of cytosine ring opening in N1-tosylcytosine, depending on the reaction conditions, peculiar tosyl-urea derivative 9 has been isolated, which provided additional insight into the reaction pathway. The influence of the C5-substituent on the antiproliferative activity has been evaluated by performing the MTT test on U251, MCF-7 and MOLT-4 tumor cell-lines. PMID- 29577138 TI - The modeling of the absorption lineshape for embedded molecules through a polarizable QM/MM approach. AB - We present a computational strategy to simulate the absorption lineshape of a molecule embedded in a complex environment by using a polarizable QM/MM approach. This strategy is presented in two alternative formulations, one based on a molecular dynamics simulation of the structural fluctuations of the system and the other using normal modes and harmonic frequencies calculated on optimized geometries. The comparison for the case of a chromophore within a strongly inhomogeneous and structured environment, namely the intercalation pocket of DNA, shows that the MD-based approach is able to reproduce the experimental spectral bandshape. In contrast, the static approach overestimates the vibronic coupling, resulting in a much broader band. PMID- 29577139 TI - Improving Luttinger-liquid plasmons in carbon nanotubes by chemical doping. AB - We realized the real-space imaging of Luttinger-liquid plasmons in semiconducting single-walled carbon nanotubes (s-SWCNTs) and studied the effects of chemical doping-induced charge carrier density modulation on plasmons. Using scattering type scanning near-field optical microscopy (s-SNOM), we compared the Luttinger liquid plasmonic behavior in pre- and post-HNO3-doped SWCNTs. Raman measurements revealed that the physical mechanism is P-type doping. Through HNO3 doping, we effectively increased the charge carrier density in s-SWCNTs and achieved quantum plasmons simultaneously with strong confinement (lambda0/lambdap ~ 70) and high quality factor (Q ~ 20). The combination of high quality factor and strong subwavelength confinement in Luttinger-liquid plasmons is critical to the future application of plasmonic devices. PMID- 29577140 TI - Bilayers of Janus and homogeneous particle mixtures trapped at an air/water interface. AB - We study mixtures of amphiphilic Janus and homogeneous hydrophobic particles trapped at an air/water interface. In contrast to an expected monolayer formation, bilayers of colloidal particles are produced. Despite their strong interfacial adsorption, Janus particles form the upper layer. They are not placed on top of the other particles but rather shifted about one-third of the particle diameter. To understand the mechanism of bilayer formation, particle behaviour at the surface and in the bulk of the spreading solvent is considered. The vertical shift and the bilayer formation are assisted by the momentous formation of two interfaces during spreading. PMID- 29577141 TI - The heat capacities and critical behaviors of binary ionic solutions. AB - The heat capacities of nine binary room temperature ionic solutions {[C4mim][BF4] + 1,2-butandiol}, {[C8mim][BF4] + 1-pentanol}, {[C8mim][BF4] + 2-pentanol}, {[C8mim][BF4] + 1-hexanol}, {[C8mim][BF4] + 1-heptanol}, {[C8mim][PF6] + 1 propanol}, {[C8mim][PF6] + 1-butanol}, {[C8mim][PF6] + 2-butanol} and {[C8mim][PF6] + tert-butanol} are reported herein. The combination of the data obtained with the corresponding measured coexistence curves infers that the critical asymmetry parameter of the coexistence curves linearly varies with the molar volume ratio of the two components for each of the studied binary ionic solutions after the heat capacity contribution is considered. This indicates the importance of the heat capacity contribution to the critical asymmetry. For further analysis of the critical characteristics of the ionic solutions, a large amount of experimental data was collected and systematically discussed in detail regarding which critical character is important in the binary ionic solutions. A general increasing tendency for the RPM (restricted primitive model)-rescaled critical parameters with the relative permittivity epsilonr,c of the solvent at the critical temperature of the corresponding system was found. This is attributed not only to the screening effect of the solvent medium, but also to solvophobic interactions, which both increase with epsilonr,c. This study also demonstrates that the critical amplitudes increased, while the relative contribution of the heat capacity to the asymmetry of the coexistence curve decreased with an increase in epsilonr,c. PMID- 29577142 TI - X-Ray diffraction and resonance shear measurement of nano-confined ionic liquids. AB - X-ray diffraction measurement at the SPring-8 synchrotron was employed to investigate the structures of two types of imidazolium-based ionic liquids (ILs), 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C4mim][NTF2]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([C4mim][BF4]), confined between silica surfaces by varying the surface separation distances of ca. 500 nm (bulk liquid), ca. 10 nm, and ca. 2 nm (hard wall thickness). The obtained diffraction profiles and intensities were discussed by considering the structures and properties of the nano-confined ILs between the silica surfaces investigated by resonance shear measurement (RSM) and molecular dynamics simulation (MD) in our previous reports. [C4mim][NTf2] showed two diffraction peaks at q = 8.8 nm-1 (spacing d = 0.71 nm) and at q = 14.0 nm-1 (spacing d = 0.45 nm) at the greatest distance (D = ca. 500 nm), which were assigned to the interval between the same ions (anion-anion or cation-cation) within the polar network of [C4mim][NTf2] and the interval between the neighboring anion-cation, respectively. The positions of these two peaks remained the same at D = ca. 10 nm and at the hard wall (D = ca. 2 nm) and their intensity factor increased, indicating that both the cation and anion existed in the same layer. This result was consistent with the checkerboard structure of [C4mim][NTf2] on the silica surface computer simulated in our previous studies. On the other hand, [C4mim][BF4] showed a peak at q = 15.4 nm-1 (spacing d = 0.41 nm) corresponding to the anion-cation interval at the greatest distance (D = ca. 500 nm). This peak became broader and weaker at D = ca. 12 nm and at D = ca. 2 nm. PMID- 29577143 TI - The art in science of MicroTAS: 10 years of miniaturized art. PMID- 29577144 TI - Scan-rate and vacuum pressure dependence of the nucleation and growth dynamics in a spin-crossover single crystal: the role of latent heat. AB - Using optical microscopy we studied the vacuum pressure dependence (0.1-1000 mbar) of the nucleation and growth dynamics of the thermally induced first-order spin transition in a single crystal of the spin-crossover compound [Fe(HB(tz)3)2] (tz = 1,2,4-triazol-1-yl). A crossover between a quasi-static hysteresis regime and a temperature-scan-rate-dependent kinetic regime is evidenced around 5 mbar due to the change of the heat exchange coupling between the crystal and its external environment. Remarkably, the absorption/dissipation rate of latent heat was identified as the key factor limiting the switching speed of the crystal. PMID- 29577145 TI - Dual effects of water vapor on ceria-supported gold clusters. AB - Atomically precise nanocatalysts are currently being intensely pursued in catalysis research. Such nanocatalysts can serve as model catalysts for gaining fundamental insights into catalytic processes. In this work we report a discovery that water vapor provokes the mild removal of surface long-chain ligands on 25 atom Au25(SC12H25)18 nanoclusters in a controlled manner. Using the resultant Au25(SC12H25)18-x/CeO2 catalyst and CO oxidation as a probe reaction, we found that the catalytic activity of cluster/CeO2 is enhanced from nearly zero conversion of CO (in the absence of water) to 96.2% (in the presence of 2.3 vol% H2O) at the same temperature (100 degrees C). The cluster catalysts exhibit high stability during the CO oxidation process under moisture conditions (up to 20 vol% water vapor). Water vapor plays a dual role in gold cluster-catalyzed CO oxidation. FT-IR and XPS analyses in combination with density functional theory (DFT) simulations suggest that the "-SC12H25" ligands are easier to be removed under a water vapor atmosphere, thus generating highly active sites. Moreover, the O22- peroxide species constitutes the active oxygen species in CO oxidation, evidenced by Raman spectroscopy analysis and isotope experiments on the CeO2 and cluster/CeO2. The results also indicate the perimeter sites of the interface of Au25(SC12H25)18-x/CeO2 to be active sites for catalytic CO oxidation. The controlled exposure of active sites under mild conditions is of critical importance for the utilization of clusters in catalysis.

AB - Ultralight benzoxazine-derived porous nitrogen self-doped carbon aerogels with good yield can be prepared by direct polymerization of trifunctional benzoxazine monomers under acid catalysis using concentrated hydrochloric acid. This allows for a significantly widened density range (0.8-4.5 mg cm-3) and avoids any sacrificial etching. When serving as electrode materials for supercapacitors, the resulting hierarchical porous carbon aerogels show ultrahigh specific capacitance, excellent rate performance and good cycling stability (retention of 97.3% even after 10 000 continuous charge-discharge cycles). Besides energy storage devices, the interconnected nanoporous carbon aerogels can also find applications in oil/water separation, heavy metal removal, catalyst supports, and so forth. PMID- 29577147 TI - Functional and stability orientation synthesis of materials and structures in aprotic Li-O2 batteries. AB - The lithium-O2 battery is one of most promising energy storage and conversion devices due to its ultrahigh theoretical energy density and hence has broad application potential in electrical vehicles and stationary power systems. However, the present Li-O2 battery suffers from a series of challenges for its practical application, such as its low capacity and rate capability, poor round trip efficiency and short cycle life. These challenges mainly arise from the sluggish and unsustainable discharge and charge reactions at lithium and oxygen electrodes, which determine the performance and durability of a battery. In this review, we first provide insights on the present understanding of the discharge/charge mechanism of such a battery and follow up with establishing a correlation between the specific materials/structures of the battery modules and their functionality/stability within the recent progress in electrodes, electrolytes and redox mediators. Considerable emphasis is paid to the importance of functional orientation design and the synthesis of materials/structures towards accelerating and sustaining the electrode reactions of Li-O2 batteries. Moreover, the future directions and perspectives of rationally constructed material and surface/interface structures, as well as their optimal combinations are proposed for enhancement of the electrode reaction rate and sustainability, and consequently for a better performance and durability of such batteries.

AB - A dual luminescence resonance energy transfer system is developed based on aptamer-functionalized upconversion nanoparticles as the energy donor and a synthetic dye derivative as the acceptor, which can be applied in the simultaneous profiling and relative quantification of phosphorylation and ubiquitination on a specific protein, even at low levels of protein expression. PMID- 29577149 TI - Sulfur-driven switching of the Ullmann coupling on Au(111). AB - We demonstrate a method to selectively switch the Ullmann coupling reaction of 2,8-dibromodibenzothiophene on a Au(111) support. The Ullmann coupling reaction is effective already at low temperature, but the complete inhibition of the same reaction can be achieved on Au(111) pre-exposed to H2S. The marked difference in reactivity of pretreated Au(111) is explained by the S-passivation of free Au atoms emerging from reconstruction sites. The inhibited state can be fully lifted by removing the S via hydrogen gas post-exposure.

AB - Perovskite-phase cesium bismuth halide (Cs3Bi2X9; X = Cl, Br, I) nanocrystals were synthesized using a hot-injection approach. These nanocrystals adopted ordered-vacancy perovskite crystal structures and demonstrated composition tunable optical properties. Growth occurred by initial formation of Bi0 seeds, and morphology was controlled by precursor and seed concentration. The Cs3Bi2I9 nanocrystals demonstrated excellent stability under ambient conditions for several months. Contrary to previous reports, we find that photoluminescence originates from the precursor material as opposed to the Cs3Bi2X9 nanocrystals.

The probe was successfully applied for the detection of both exogenous and endogenous HClO in living cells. Using the probe-based tool, we could observe the H2S-induced HClO biogenesis in living cells for the first time.

AB - Triphenyleneethynylene (TPE) monolayers at the solution-HOPG interface are oligomerized by the oxidation of pendant thioethers to form disulfide cross links. The oligomerized TPE monolayer adheres strongly to HOPG. Disulfide reduction unzips the oligomers to form a monomeric TPE monolayer with pendant thiols. Subsequent oxidation and reduction treatments zip and unzip the monolayer. PMID- 29577153 TI - Time dependence of NMR observables reveals salient differences in the accumulation of early aggregated species between human islet amyloid polypeptide and amyloid-beta. AB - Type 2 diabetes mellitus and Alzheimer's disease are characterized by the accumulation of fibrillar amyloid deposits consisting mainly of islet amyloid polypeptide (IAPP) and amyloid-beta (Abeta), respectively. Fibril formation is a multi-step nucleation process that involves the transient build-up of oligomeric species that are thought to be the most toxic components. To gain more insight into the molecular mechanism of early IAPP aggregated species formation, we performed a combination of direct and indirect biophysical approaches on IAPP and also on Abeta42 for the sake of comparison. Thioflavin T fluorescence kinetics measurements revealed a stronger autocatalytic behaviour of IAPP and a weaker concentration dependence of fibrillization half-time t1/2, as compared to Abeta42. Our NMR experiments highlight the absence of micelle reservoir or supercritical regime in the studied concentration range, indicating that the low concentration dependence of IAPP fibril formation can be ascribed to saturable pathways. IAPP and Abeta42 displayed marked differences in formation of oligomeric species, as observed by 1D 1H, pulsed-field gradient (PFG) diffusion and saturation transfer difference (STD) NMR experiments. A fast equilibrium between monomer and oligomeric species was detected in the case of Abeta42 but not IAPP, with a significant build-up of aggregated species, as shown by the time dependence of diffusion coefficient and STD magnetization transfer efficiency during the aggregation process. Altogether our data show significant differences between IAPP and Abeta42 regarding the microscopic events of amyloid species formation. PMID- 29577154 TI - Noninvasive and prospective diagnosis of coronary heart disease with urine using surface-enhanced Raman spectroscopy. AB - A prospective diagnosis method for coronary heart disease (CHD) using human urine based on surface-enhanced Raman spectroscopy (SERS) is proposed, and could provide valuable information for judging whether to perform percutaneous coronary intervention (PCI) in clinics. Here, urine samples from 87 patients with CHD, including patients with PCI before operation (degree of cardiovascular congestion above 70%) and without PCI (degree of cardiovascular congestion under 70%), and 20 healthy humans were measured using SERS. Principal component analysis (PCA) combined with linear discriminant analysis (LDA) was employed to analyze the SERS spectra, revealing that the classification sensitivity and specificity were 90% and 78.9%, respectively, and the absolute value for loading of PC1 at 1509 cm-1 was the largest. Since platelet-derived growth factor-BB (PDGF-BB) is closely related to CHD, PDGF-BB aqueous solutions with various concentrations (1, 0.5, 0.1, 0.05 and 0.01 ppm) and a mixture of healthy human urine and PDGF-BB aqueous solutions were then investigated in this work, and it was found that the Raman peak at 1509 cm-1 may be attributed to PDGF-BB. Moreover, the measured SERS spectra of all the urine samples from the 87 patients with CHD were compared with the clinical data provided by a hospital, and it was revealed that the appearance of a peak at 1509 cm-1 in the SERS spectra was in good agreement with the results of coronary angiography tests when cardiovascular congestion was above 70%. This indicated that the classification sensitivity and specificity were 87.9% and 87.0%, respectively, through identification of the Raman peak at 1509 cm-1.

AB - Luminescent thermometers based on transition metal and lanthanide ion codoped nanocrystals have become a group of non-contact thermometers which are gaining importance due to their high sensitivity upon temperature changes. Here we present two types of luminescent thermometers, namely, bandshape and lifetime temperature sensors based on Y3Al5O12:Mn3+,Mn4+,Nd3+ nanocrystals. Their ability for temperature sensing was investigated as a function of Mn concentration. It was found that both sensitivity and usable temperature range depend on the Mn concentration. The highest sensitivity (S = 2.69%/K) was found for the lifetime luminescent thermometer with 0.01%Mn concentration and its value is gradually reduced with Mn content. Similarly, in the case of the bandshape luminescent thermometer, the sensitivity decreases from 1.69%/K for 0.01%Mn to 0.54%/K for 1%Mn. On the other hand the usable temperature range extends with dopant concentration. The concentration effect on the temperature dependent optical parameters is discussed in terms of interionic interactions facilitated for shorter Mn-Mn distances. PMID- 29577157 TI - 2D carbon sheets with negative Gaussian curvature assembled from pentagonal carbon nanoflakes. AB - Despite the good progress made in materials fabrication, it remains a big challenge to synthesize 2D sheets by assembling nanoflakes that are usually produced in experiments, and few theoretical studies have explored this topic. Based on the recent experimental synthesis of pentagonal graphene nanoflakes and the novel properties of penta-graphene, we report a series of 2D assembled carbon allotropes (CG568-80, CG568-180 and CG568-320) that have the following unusual properties: different from most other 2D carbon allotropes, the assembled carbon sheets have negative Gaussian curvatures, and exhibit ultra-softness and better chemical reactivity due to the curvature-induced misalignment of pi-orbitals as compared with pristine graphene; all three studied carbon sheets are highly stable with binding energies comparable to those of phagraphene and psi-graphene, and are semiconductors with tunable band gaps, displaying size-dependent carrier mobilities: ~105 cm2 V-1 s-1 (CG568-80 and CG568-320) and ~104 cm2 V-1 s-1 (CG568 180). These features indicate that assembling nanoflakes can effectively tune the structural morphology and properties to expand the family of 2D carbon materials for future applications. PMID- 29577158 TI - Determination of accurate backbone chemical shift tensors in microcrystalline proteins by integrating MAS NMR and QM/MM. AB - Chemical shifts are highly sensitive probes of local conformation and overall structure. Both isotropic shifts and chemical shift tensors are readily accessible from NMR experiments but their quantum mechanical calculations remain challenging. In this work, we report and compare accurately measured and calculated 15NH and 13Calpha chemical shift tensors in proteins, using the microcrystalline agglutinin from Oscillatoria agardhii (OAA). Experimental 13Calpha and 15NH chemical tensors were obtained by solid-state NMR spectroscopy, employing tailored recoupling sequences, and for their quantum mechanics/molecular mechanics (QM/MM) calculations different sets of functionals were evaluated. We show that 13Calpha chemical shift tensors are primarily determined by backbone dihedral angles and dynamics, while 15NH tensors mainly depend on local electrostatic contributions from solvation and hydrogen bonding. In addition, the influence of including crystallographic waters, the molecular mechanics geometry optimization protocol, and the level of theory on the accuracy of the calculated chemical shift tensors is discussed. Specifically, the power of QM/MM calculations in accurately predicting the unusually upfield shifted 1HN G26 and G93 resonances is highlighted. Our integrated approach is expected to benefit structure refinement of proteins and protein assemblies.

AB - Self-organization processes of a gear-shaped amphiphile molecule (1) to form a hexameric structure (nanocube, 16) were inferred from sequential dissociation processes by using molecular dynamics (MD) simulations. Our MD study unveiled that programed dynamic ordering exists in the dissociation processes of 16. According to the dissociation processes, it is proposed that triple pi-stacking among three 3-pyridyl groups and other weak molecular interactions such as CH-pi and van der Waals interactions, some of which arise from the solvophobic effect, were sequentially formed in stable and transient oligomeric states in the self organization processes, i.e.12, 13, 14, and 15. By subsequent analyses on structural stabilities, it was found that 13 and 14 are stable intermediate oligomers, whereas 12 and 15 are transient ones. Thus, the formation of 13 from three monomers and of 16 from 14 and two monomers via corresponding transients is time consuming in the self-assembly process.

AB - High-grade ovarian serous cancer is known for its high rates of invasion and metastasis, and resultant high mortality rate. Therefore, research concerning biomarkers and underlying molecular mechanisms of high-grade ovarian serous cancer progression and prognosis are urgently required. Long non-coding RNAs (lncRNAs) have been the subject of an increasing number of studies, and certain lncRNAs have been demonstrated to serve an important function in the development and progression of various cancers, including HOX transcript antisense RNA, competing endogenous lncRNA 2 for microRNA let-7b, urothelial cancer associated 1, and H19, imprinted maternally expressed transcript (non-protein coding). However, few studies have investigated the differential expression of lncRNAs in high-grade ovarian serous cancer. In the present study, differences in lncRNA and mRNA expression profiles between high-grade ovarian serous cancer tissue samples and healthy fallopian tube tissue samples were investigated using microarray analysis, and the differential expression of lncRNAs and mRNAs was confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Then, five abnormally expressed lncRNAs were selected, and the associations between these lncRNAs and ovarian cancer clinicopathological parameters were examined using RT-qPCR. The expression profiles of certain lncRNAs and mRNAs were confirmed to be altered between high-grade ovarian serous cancer tissues and healthy fallopian tube tissues. Furthermore, the expression levels of selected lncRNAs were associated with International Federation of Gynecology and Obstetrics stage and lymph node metastasis. These lncRNAs and mRNAs may therefore be involved in the pathogenesis of high-grade ovarian serous cancer. The results of the present study provide an experimental foundation for further exploration of the value of these lncRNAs and mRNAs in the early diagnosis and treatment of high-grade ovarian serous cancer.

AB - beta-Catenin exerts multiple functions in several neoplasms, playing a major role in cell signaling and tumor progression. This study analyzed possible CTNNB1 mutations in salivary gland pleomorphic adenomas (PAs) and adenoid cystic carcinomas (ACCs), and determined possible differences in beta-catenin immunoexpression in relation to these mutations, as well as histopathological aspects of these tumors. Twenty-four PAs (15 cell-rich and 9 cell-poor tumors) and 24 ACCs (10 tubular, 8 cribriform, and 6 solid tumors) were selected for the analysis of beta-catenin distribution and cellular localization. Furthermore, beta-catenin expression was evaluated using the H-score scoring system. Mutations in CTNNB1 exon 3 were investigated by the single-strand conformational polymorphism test. Diffuse beta-catenin expression was more frequently observed in ACCs compared to PAs (P = 0.008). No significant difference in beta-catenin cellular localization was observed between these tumors (P = 0.098). Comparisons between PA and ACC cases revealed a higher median H-score in the latter (P = 0.036). Cell-rich PAs exhibited a trend for higher H-score than cell-poor tumors (P = 0.060), whereas lower H-scores were observed in cribriform ACCs when compared to tubular and solid ACCs (P = 0.042). Mutations in CTNNB1 were observed in 6 PAs and 7 ACCs, with no significant difference in H-scores for beta-catenin according to mutation status (P = 0.135). beta-Catenin is important in the pathogenesis of salivary gland PAs and ACCs. In addition, CTNNB1 exon 3 mutations do not seem to significantly influence beta-catenin cytoplasmic/membranous expression or nuclear translocation in these tumors.

AB - D-Allose is a rare monosaccharide, which rarely appears in the natural environment. D-Allose has an 80% sweetness relative to table sugar but is ultra low calorie and non-toxic and is thus an ideal candidate to take the place of table sugar in food products. It displays unique health benefits and physiological functions in various fields, including food systems, clinical treatment, and the health care fields. However, it is difficult to produce chemically. The biotechnological production of D-allose has become a research hotspot in recent years. Therefore, an overview of recent studies on the physiological functions, applications, and biotechnological production of D allose is presented. In this review, the physiological functions of D-allose are introduced in detail. In addition, the different types of D-allose-producing enzymes are compared for their enzymatic properties and for the biotechnological production of D-allose. To date, very little information is available on the molecular modification and food-grade expression of D-allose-producing enzymes, representing a very large research space yet to be explored. PMID- 29577168 TI - Spatial factors of white-tailed deer herbivory assessment in the central Appalachian Mountains. AB - Because moderate to over-abundant white-tailed deer (Odocoileus virginianus) herbivory impacts biodiversity and can alter community function, ecological benchmarks of herbivory impact are needed to assess deer impacts. We evaluated spatial patterns of deer herbivory and their relation to herbivory assessment by evaluating woody vegetation along 20 transects at each of 30 sites spread across a wide range of deer herd densities and vegetative condition throughout the biodiverse Appalachian Mountains of Virginia, USA. Surprisingly, herbivory patterns and the availability of woody forage generally were unchanged among physiographic regions and land use diversity classes. However, some relationships between browsing pattern and vegetation varied with scale. The total quantity of vegetation browsed on a given site and at the transect scale were related positively to the availability of forage, as the proportion of stems browsed decreased as stem density increased. However, this was only true when all stems were considered equally. When stem densities by species were weighted for deer preference, the proportion of stems browsed had no relationship or increased with stem density. Compared to the value from all transects sampled, on average, the mean of >= 3 transects within a site was within 0.1 of the browsing ratio and stem densities were within 0.5 stems m-2. Our results suggest that one transect per square kilometer with a minimum of three transects may be sufficient for most browsing intensity survey requirements to assess herbivory impacts in the Appalachian region of Virginia. Still, inclusion of spatial factors to help partition variation of deer herbivory potentially may allow for improved precision and accuracy in the design of field herbivory impact assessment methods and improve their application across various landscape contexts. PMID- 29577166 TI - An international Urogynecological association (IUGA)/international continence society (ICS) joint report on the terminology for the assessment of sexual health of women with pelvic floor dysfunction. AB - INTRODUCTION AND HYPOTHESIS: The terminology in current use for sexual function and dysfunction in women with pelvic floor disorders lacks uniformity, which leads to uncertainty, confusion, and unintended ambiguity. The terminology for the sexual health of women with pelvic floor dysfunction needs to be collated in a clinically-based consensus report. METHODS: This report combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA), and the International Continence Society (ICS), assisted at intervals by many external referees. Internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). Importantly, this report is not meant to replace, but rather complement current terminology used in other fields for female sexual health and to clarify terms specific to women with pelvic floor dysfunction. RESULTS: A clinically based terminology report for sexual health in women with pelvic floor dysfunction encompassing over 100 separate definitions, has been developed. Key aims have been to make the terminology interpretable by practitioners, trainees, and researchers in female pelvic floor dysfunction. Interval review (5-10 years) is anticipated to keep the document updated and as widely acceptable as possible. CONCLUSIONS: A consensus based terminology report for female sexual health in women with pelvic floor dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

AB - Alzheimer's disease (AD) is a progressive brain disease. The goal of this study is to provide a new computer-vision based technique to detect it in an efficient way. The brain-imaging data of 98 AD patients and 98 healthy controls was collected using data augmentation method. Then, convolutional neural network (CNN) was used, CNN is the most successful tool in deep learning. An 8-layer CNN was created with optimal structure obtained by experiences. Three activation functions (AFs): sigmoid, rectified linear unit (ReLU), and leaky ReLU. The three pooling-functions were also tested: average pooling, max pooling, and stochastic pooling. The numerical experiments demonstrated that leaky ReLU and max pooling gave the greatest result in terms of performance. It achieved a sensitivity of 97.96%, a specificity of 97.35%, and an accuracy of 97.65%, respectively. In addition, the proposed approach was compared with eight state-of-the-art approaches. The method increased the classification accuracy by approximately 5% compared to state-of-the-art methods. PMID- 29577170 TI - Robotic rectal cancer surgery in obese patients may lead to better short-term outcomes when compared to laparoscopy: a comparative propensity scored match study. AB - PURPOSE: Laparoscopic rectal surgery in obese patients is technically challenging. The technological advantages of robotic instruments can help overcome some of those challenges, but whether this translates to superior short term outcomes is largely unknown. The aim of this study is to compare the short term surgical outcomes of obese (BMI >= 30) robotic and laparoscopic rectal cancer surgery patients. METHODS: All consecutive obese patients receiving laparoscopic and robotic rectal cancer resection surgery from three centres, two from the UK and one from Portugal, between 2006 and 2017 were identified from prospectively collated databases. Robotic surgery patients were propensity score matched with laparoscopic patients for ASA grade, neoadjuvant radiotherapy and pathological T stage. Their short-term outcomes were examined. RESULTS: A total of 222 patients were identified (63 robotic, 159 laparoscopic). The 63 patients who received robotic surgery were matched with 61 laparoscopic patients. Cohort characteristics were similar between the two groups. In the robotic group, operative time was longer (260 vs 215 min; p = 0.000), but length of stay was shorter (6 vs 8 days; p = 0.014), and thirty-day readmission rate was lower (6.3% vs 19.7%; p = 0.033). CONCLUSIONS: In this study population, robotic rectal surgery in obese patients resulted in a shorter length of stay and lower 30-day readmission rate but longer operative time when compared to laparoscopic surgery. Robotic rectal surgery in the obese may be associated with a quicker post operative recovery and reduced morbidity profile. Larger-scale multi-centre prospective observational studies are required to validate these results.

AB - OBJECTIVES: To analyse social inequalities in the association between ambient temperature and mortality by sex, age and educational level, in the city of Barcelona for the period 1992-2015. METHODS: Mortality data are represented by daily counts for natural mortality. As a measure of socioeconomic position, we used the educational level of the deceased. We also considered age group and sex. We considered, as a measure of exposure, the daily maximum temperatures. Time series Poisson regression with distributed lag non-linear models was fitted for modelling the relationship between temperature and mortality. RESULTS: Women had higher risk of mortality by hot temperatures than men. Temperature-mortality association (heat and cold) was evident for the elderly, except for heat-related mortality in women which was present in all age groups. Men with primary education or more were more vulnerable to moderate or extreme temperatures than those without studies. Finally, women were vulnerable to heat-related mortality in all educational levels while women without studies were more vulnerable to cold temperatures. CONCLUSIONS: Social and economic individual characteristics play an important role in vulnerability to high and low temperatures. It is important that decision-making groups consider identified vulnerable subgroups when redacting and implementing climate change resilience and adaptation plans. PMID- 29577172 TI - Parafoveal and optic disc vessel density in patients with obstructive sleep apnea syndrome: an optical coherence tomography angiography study. AB - AIMS: To compare optic disc perfusion, radial peripapillary capillaries (RPC) and macular vascular density, between normal subjects and subjects with obstructive sleep apnea syndrome (OSAS) using spectral-domain OCT angiography (OCTA). METHODS: Sixteen eyes of patients with mild OSAS, 17 eyes with moderate OSAS, 20 eyes with severe OSAS on polygraphy and 28 controls were evaluated with OCTA RT XR Avanti (AngioVue software, Optovue Inc., Fremont, CA). Optic nerve head (ONH), RPC and macular vessel density were measured. Clinical data, visual field parameters, and Spectral Domain OCT evaluation (retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC) thickness) were recorded for all patients. RESULTS: ONH vascular flow (p = 0,396), RPC vascular density (automatized data "whole" p = 0,913, "peripapillary" p = 0,539, and segmented analysis with a topographic grid) and macular vascular density (foveal p = 0,484, parafoveal p = 0,491) were not significantly different between the four groups. FDT-MatrixTM and Humphrey 24/2 mean deviation were significantly lower in eyes with severe OSAS and were correlated to the apnea-hypopnea index. Retinal nerve fiber layer (RNFL) thickness, Cup/Disc ratio, rim area, and ganglion cell complex (GCC) were not significantly modified. CONCLUSIONS: OCTA did not detect reduced ONH, RPC, neither macular blood vessel density in eyes with OSAS. The precise mechanisms that link OSAS with optic nerve pathologies remain unclear: our study was not able to demonstrate a vascular impact by OCTA examination. PMID- 29577173 TI - Effect of replacing concentrate feed with leaves of Oldman saltbush (Atriplex nummularia) on feed intake, weight gain, and carcass parameters of highland sheep fed on wheat straw in northern Ethiopia. AB - Atriplex nummularia (oldman saltbush) is widely planted on salt-affected land to provide a vegetative cover, which can be used as an alternative feed resource. The study was conducted to evaluate the replacement of commercial concentrate with oldman saltbush (SB) leaf on the feed intake, live weight gain, and carcass parameters of local sheep. Twenty-five sheep with an age of 6 months and weighting 14.60 +/- 2.47 kg were used in randomized complete block design and distributed into five equal groups, with five animals each. The selected sheep were fed with the dietary treatments for 2 weeks for adaptation and continued until the end of the study, which lasted for 90 days. In the control treatment (SB-0), sheep were fed 100% concentrate mix, while in SB-5, SB-10, SB-15, and SB 20, 5, 10, 15, and 20% of the concentrate mix was replaced by SB, respectively. Wheat straw and water were given at ad libitum throughout the experiment period. Data on feed intake and live weight gain were recorded daily and weekly, respectively, for 90 days. Three animals from each treatment were slaughtered for carcass analysis. Atriplex nummularia leaf (Oldman saltbush) contained 92.02% dry matter (DM), 21.99% crude protein (CP), 24.77% ash, 58.27% neutral detergent fiber (NDF), and 26.56% acid detergent fiber (ADF). Dry matter intake, live weight gain, and carcass parameter were not statistically different among the treatments. Result indicated that concentrate feed can be replaced with Atriplex nummularia leaf up to 20% in sheep diet without negative effect on growth performance and carcass characteristics.

AB - Simple non-associative learning processes, habituation and sensitization, are known to be systemically involved in different neurotransmissions, and these processes in the vestibular nucleus (VN) often show opposite responding patterns to repeated stimuli. However, their roles and mechanisms of the reciprocal responses at the cellular level are still elusive. Here, we conducted an electrophysiological experiment to investigate the neuronal responses to repeated stimuli in the VN, characterizing the neuronal responding patterns of habituation and sensitization. Based on our results, we also suggested an alternative hypothesis that these non-associative neuronal responses generated biased neural information based on simple linear addition. Sixty-seven neuronal responses to repeated stimuli were recorded from 23 guinea pigs, and the habituated and the sensitized responses were 37 (range of slopes - 3.66~- 0.02 spks/s/trial) and 30 (0.01~1.51 spks/s/trial), respectively. Unlike previous study, the general neuronal responding shapes were not exponential, but most (94%, 63/67) responding profiles were linear. Although no strong relation between the irregular and the high sensitivity in our population, the neuronal irregularity and sensitivity could be the core factors to cause the biased results to more habituated side. In conclusion, we found that a biased neural response (mean +/- STD - 0.22 +/- 0.89 spks/s/trial) was constructed by two non-associative neuronal responses based on a linear addition of the slopes. Graphical abstract Hypothesized and calculated neural mediation by non-associative learning processes. PMID- 29577176 TI - Glutamate receptors of the A5 region modulate cardiovascular responses evoked from the dorsomedial hypothalamic nucleus and perifornical area. AB - To assess the possible function of glutamate in the interaction between the dorsomedial hypothalamic nucleus-perifornical area (DMH-PeF) and the A5 pontine region (A5), cardiovascular and respiratory changes were studied in response to electrical stimulation of the DMH-PeF (1 ms pulses, 30-50 MUA given at 100 Hz for 5 s) before and after the microinjection of kynurenic acid (non-specific glutamate receptor antagonist; 50 nl, 5 nmol), MK-801 (NMDA receptor antagonist; 50 nl, 50 nmol), CNQX (non-NMDA receptor antagonist; 50 nl, 50 nmol) or MCPG (metabotropic glutamate receptor antagonist; 50 nl, 5 nmol) within the A5 region. DMH-PeF electrical stimulation elicited a pressor (p < 0.001) and tachycardic response (p < 0.001) which was accompanied by an inspiratory facilitation characterised by an increase in respiratory rate (p < 0.001) due to a decrease in expiratory time (p < 0.01). Kynurenic acid within the A5 region decreased the tachycardia (p < 0.001) and the intensity of the blood pressure response (p < 0.001) to DMH-PeF stimulation. After the microinjection of MK-801 and CNQX into the A5 region, the magnitude of the tachycardia and the pressor response were decreased (p < 0.05 and p < 0.01; p < 0.001 and p < 0.05, respectively). After MCPG microinjection into the A5 region, a decrease in the tachycardia (p < 0.001) with no changes in the pressor response was observed during DMH-PeF stimulation. The respiratory response elicited by DMH-PeF stimulation was not changed after the microinjection of kynurenic acid, MK-801, CNQX or MCPG within the A5 region. These results suggest that A5 region glutamate receptors play a role in the cardiovascular response elicited from the DMH-PeF. The possible mechanisms involved in these interactions are discussed.

PMID- 29577177 TI - Ocular Pharmacokinetics of 25-Hydroxyvitamin D3 After Weekly Supplementation in Rabbits Using Ultra Performance Liquid Chromatography-Tandem Mass Spectrometer. AB - BACKGROUND AND OBJECTIVES: The protective role of vitamin D supplementation has recently been shown to be present in various ocular inflammatory diseases. The oral supplementation of vitamin D may take time to achieve adequate levels in intraocular fluids. Therefore, the present study was performed to understand the ocular pharmacokinetics of 25-hydroxyvitamin D3 (25D3) in aqueous humor after weekly supplementation of 25D3 in rabbits. METHODS: A total of 21 rabbits were fed orally with 25D3 (7.22 ug/kg/week) for 8 weeks and 9th dose was given at the end of 8 weeks. The blood and aqueous humor samples were collected from ear vein and though anterior chamber paracentesis, respectively. The serum and aqueous humor samples were spiked with deuterium labeled internal standard and were extracted using liquid extraction method. Furthermore, the samples were derivatized and 25D3 estimation was performed using ultra performance liquid chromatography-tandem mass spectrometer (UHPLC-MS/MS). RESULTS: The 25D3 supplementation significantly increased the 25D3 levels in serum (78.5 +/- 21.6 ng/ml) (mean +/- SD) (p < 0.0001) and in aqueous humor (991.3 +/- 180.6 pg/ml) (mean +/- SD) (p < 0.0001) compared to baseline levels. The maximum concentration was achieved in serum after the 10th hour of supplementation of 1st and 9th dose, while the same was observed at the 24th hour in aqueous humor. CONCLUSION: The oral supplementation of 25D3 was found to significantly increase 25D3 levels in aqueous humor; however, the time required to achieve 25D3 concentration in aqueous humor was higher as compared to that in serum. Therefore, weekly oral supplementation of 25D3 may have a beneficial role in ocular diseases.

AB - INTRODUCTION: The aim of this study was to survey the nucleotide changes and copy number variations (CNV) in the CDH1 gene in Iranian patients with sporadic diffuse gastric cancer (SDGC). MATERIALS AND METHODS: In this study, 28 patients were examined who upon gastrectomy had been diagnosed with SDGC according to the familial history and histopathological criteria which was confirmed by the pathologist. DNA extraction was performed from formalin-fixed paraffin-embedded tissues using a phenol-chloroform method following xylene deparaffinization. Determination of DNA sequence by Sanger was performed using PCR amplification of 16 exons and boundaries of intron/exon of CDH1 gene. Multiplex ligation-dependent probe amplification (MLPA) was performed on patients with pathogenic disorders in the sequence. RESULTS: In total, patients included 20 males and 8 females. Of all patients, 12 patients were under 45 years old (early onset gastric cancer, EODC) and 16 patients were older. The tumor was diagnosed in the early TNM stage (I, II) in six patients and in late stages (III, IV) in 19 cases. Altogether, 16 variants (three exonic with one new variant and 13 intronic with nine new variants) were found in DNA sequencing of the CDH1 gene in five samples. Also, using MLPA, a new duplication in exon 9 and one deletion in exon 2 were detected in two other patients. Altogether, CDH1 variants were identified in seven out of 28 patients (25%). CONCLUSION: Our study revealed several novel somatic variants in the CDH1 gene in Iranian patients with sporadic diffuse GC. Our data supports the hypothesis that mutations in CDH1 gene, and particularly the mutations we describe, should be considered, even in sporadic cases of gastric cancer. The presence of these mutations in patients raises important issues regarding genetic counseling and diagnostic test in DGC patients.

AB - The objectives of this study were to study the clinical and biochemical profile of neonates with sepsis and to evaluate the diagnostic role of presepsin and its comparison with C-reactive protein (CRP) and Procalcitonin (PCT). This study was conducted from March 2015 through October 2016 in Neonatal intensive care unit (NICU) at S N Medical College, Agra. Neonates with >=1 clinical features of sepsis and/or two risk factors were included. A total of 41 cases and 41 controls were taken. Blood sample was taken for all investigations. ROC curve analysis was performed. Out of 41 cases, 19 were blood culture positive, majority were males (68.3%), low birth weight (LBW: 70.7%) and preterms (53.6%). At chosen cut-off values, sensitivity of CRP, PCT and presepsin was 80.5%, 80.5%, 97.6% and specificity was 97.5%, 80.5%, 95.1% respectively. PCT and CRP were comparable as diagnostic markers of neonatal sepsis. Presepsin, in comparison with CRP and PCT has better sensitivity and negative predictive value (NPV). PMID- 29577182 TI - Mercury Bioaccumulation in Tropical Mangrove Wetland Fishes: Evaluating Potential Risk to Coastal Wildlife. AB - The present study, aimed at observing the total concentration of mercury (Hg) in edible finfish species with an implication to human health risk, was carried out from the Setiu mangrove wetlands on the east coast of Peninsular Malaysia. Out of 20 species observed, the highest Hg concentrations were found among carnivores fish/invertebrate-feeders, followed by omnivores and carnivores-invertebrate feeders, while the lowest concentrations in herbivores. The Hg concentrations varied widely with fish species and body size, from 0.12 to 2.10 mg/kg dry weight. A positive relationship between body weight and Hg concentration was observed in particular for Toxotes jaculatrix and Tetraodon nigroviridis. Besides the permissible range of Hg concentration up to 0.3 mg/kg (cf. United States Environmental Protection Agency (USEPA)) in majority of species, the carnivore feeders such as Acanthopagrus pacificus, Gerres filamentosus, and Caranx ignobilis have shown excess amounts (> 0.40 mg/kg flesh weight) that raising concerns over the consumption by local people. However, the weekly intake of mercury-estimated through the fish consumption in all three trophic levels suggests that the present Hg concentrations are still within the range of Provisional Tolerable Weekly Intake (PTWI) reported by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Perhaps, a multi-species design for Hg monitoring at Setiu wetlands would be able to provide further insights into the level of toxicity transfer among other aquatic organisms and thereby a strong health risk assessment for the local communities. PMID- 29577184 TI - Endogenous Regulators of the Immune System (sCD100, Malonic Dialdehyde, and Arginase). AB - Tissue damage in various diseases, hypoxic conditions, and some pathologies are associated with production of endogenous factors such as the soluble form of the surface receptor CD100, malonic dialdehyde, and arginase and their release into circulation. These factors modulate functional state of lymphocytes in the immune system: potentiate activation of B lymphocytes, activate synthesis and secretion of IL-25 and IL-17 cytokines, and suppress proliferative activity of T lymphocytes, thus modulating immunological reactivity of the organism. Reactions of innate and adaptive immunity develop against the background of changed immunological reactivity, which should be taken into account in the development of pathogenetically substantiated therapy. PMID- 29577183 TI - Developing novel methods to image and visualize 3D genomes. AB - To investigate three-dimensional (3D) genome organization in prokaryotic and eukaryotic cells, three main strategies are employed, namely nuclear proximity ligation-based methods, imaging tools (such as fluorescence in situ hybridization (FISH) and its derivatives), and computational/visualization methods. Proximity ligation-based methods are based on digestion and re-ligation of physically proximal cross-linked chromatin fragments accompanied by massively parallel DNA sequencing to measure the relative spatial proximity between genomic loci. Imaging tools enable direct visualization and quantification of spatial distances between genomic loci, and advanced implementation of (super-resolution) microscopy helps to significantly improve the resolution of images. Computational methods are used to map global 3D genome structures at various scales driven by experimental data, and visualization methods are used to visualize genome 3D structures in virtual 3D space-based on algorithms. In this review, we focus on the introduction of novel imaging and visualization methods to study 3D genomes. First, we introduce the progress made recently in 3D genome imaging in both fixed cell and live cells based on long-probe labeling, short-probe labeling, RNA FISH, and the CRISPR system. As the fluorescence-capturing capability of a particular microscope is very important for the sensitivity of bioimaging experiments, we also introduce two novel super-resolution microscopy methods, SDOM and low-power super-resolution STED, which have potential for time-lapse super-resolution live cell imaging of chromatin. Finally, we review some software tools developed recently to visualize proximity ligation-based data. The imaging and visualization methods are complementary to each other, and all three strategies are not mutually exclusive. These methods provide powerful tools to explore the mechanisms of gene regulation and transcription in cell nuclei.

AB - We analyzed variability of the expression of three reference genes in biopsy samples of the olfactory epithelium obtained from healthy volunteers. The expression of B2M, HPRT1, and CASC3 genes was analyzed by real-time PCR. The pairs of genes B2M-HPRT1 and B2M-CASC3 were found to possess minimum individual variability of expression and can be reliable candidates for the reference genes in analysis of gene expression in neural cells. PMID- 29577186 TI - Antitumor Activity of Fascaplysin Derivatives on Glioblastoma Model In Vitro. AB - Antitumor efficiency of fascaplysin synthetic derivatives (7-phenylfascaplysin, 3 chlorofascaplysin, 3-bromofascaplysin, and 10-bromofascaplysin) was compared out in vitro on C6 glioma cells. The cytotoxic efficiency of all tested compounds was higher than that of unsubstituted fascaplysin; 3-bromofascaplysin and 7 phenylfascaplysin exhibited the best capacity to kill glioma C6 cells. Apoptosis was the main mechanism of glioma cell death. The cytotoxic activity of these compounds increased with prolongation of exposure to the substance and increase of its concentration. Fascaplysin derivatives modified all phases of glioma cell vital cycle. The count of viable tumor cell in G0 phase remained minimum by the end of experiment under the effects of 3-bromofascaplysin and 7 phenylfascaplysin.

AB - We studied the effect of PGRPs-Hsp70 cytotoxic complex that is analogous to natural complex secreted by cytotoxic lymphocytes and the antitumor drug paclitaxel on the development of M3 melanoma in DBA mice. Significant inhibition of tumor growth was observed in all experimental groups by days 20 and 35 of observation; paclitaxel monotherapy was less effective than administration of PGRPs-Hsp70 cytotoxic complex and its combination with paclitaxel. Pairwise comparison of Kaplan-Meier curves showed that survival was maximum in the group receiving combined therapy with PGRPs-Hsp70 cytotoxic complex and paclitaxel in comparison with groups receiving monotherapy. PMID- 29577188 TI - Decrease in Bcl-2 Protein Level during the Development of Lewis Carcinosarcome. AB - We studied the development of Lewis carcinoma and possible antitumor effect of preliminary administered antioxidant anphen. The tumor was intramuscularly transplanted to C57Bl*DBA mice (7*106 cells per mouse). According to immunoblotting results, the content of anti-apoptotic Bcl-2 protein steadily decreased starting from post-transplantation day 11. In few days, its content decreased by 15-20% and soon the animals died. After administration of anphen, the content of Bcl-2 decreased more rapidly than in the control. Atomic force microscopy revealed a decrease in the mean volume of erythrocytes and then increase in this parameter at the terminal stage of tumor growth. These findings suggest that anphen does not affect the tumor growth rate and mouse lifespan, but enhances apoptosis of blood cells of animals with Lewis carcinoma at the terminal stages of tumor growth.

AB - The effects of various treatment modes on the morphology of anterior mediastinal lymph nodes were examined in female Wistar rats with chemically provoked breast cancer. Adjuvant chemotherapy impaired filtration barrier potential of the anterior mediastinal lymph nodes, which manifested in increased volume of sinuses, reduced volumes of lymphoid nodules with germinal centers and thymus dependent regions, down-regulated proliferative activity of lymphoid cells in B cell zone and paracortex, and diminished macrophage score in all zones. Intraperitoneal injection of double-stranded DNA preparation (5 mg/kg) activated the humoral and cellular immune responses manifested by morphological alterations in anterior mediastinal lymph nodes observed in parallel with a decrease of medullary sinuses volume: enhancement of lymphocyte volume and lymphocyte score in paracortex, mantle zone expansion, and an increase of volume of the light centers in lymphoid nodules paralleled with diminished proliferative activity in them.

AB - Studies of the molecular mechanisms of esophageal cancer development have to be carried out on sufficient amount of tumor material, obtained under conditions of controlled exposure to carcinogenic factors. Esophageal cancer models on laboratory animals serve an indispensable source of this material. One of these models is esophageal cancer induction in rats by N-nitroso compound precursors. Despite adequate reproduction of human esophageal cancer, this model in fact has not been used since the 1990ies. Re-examination of esophageal cancer model, induced by N-nitrososarcosine ethyl ester precursors, is carried out and its efficiency in induction of squamous cell carcinoma is confirmed.

AB - Experimental validation of the method for regulation of stem cell proliferation and differentiation is carried out. The method consists in exposure to ultrahigh frequency electromagnetic radiation, modulated by infralow frequencies with variable parameters. A specially designed programmer, setting up the parameters of exposure, is connected to the source of radiation. The zones of anatomical location of the red bone marrow of rats were exposed for 15 min to the amplitude modulated electromagnetic radiation of ultrahigh frequency range. The parameters of exposure were determined in previous studies. The red bone marrow was collected from the sternum and head of the femur. The cellular composition of the red bone marrow was evaluated 1, 2, 3, and 6 days after the exposure. The optimal therapeutic mode of irradiation was then chosen, leading to stem cell activation with subsequent proliferation and differentiation into mature red bone marrow cells.

AB - Functional interactions of sympathetic fibers innervating the iris with the neurons of central origin in intraocular transplants of the rat hippocampus were studied by optic, confocal, and electron microscopy. After formaldehyde fixation, fluorescent dye Dil was applied to the upper cervical ganglion; the dye migrated to the transplant by lateral diffusion via axons. Sympathetic nerves labeled with fluorescent dye grew into the neurotransplants along perivascular membranes of blood vessels. In addition, some fluorescent axons were identified in the transplant parenchyma. Electron microscopy showed large bundles of the peripheral type axons in the vascular adventitia and Schwann-axonal complexes in the transplant neuropil. Autonomic axons formed synaptic contacts with transplanted neurons. PMID- 29577193 TI - Changes in the Expression of Immune Proteasomes in the Liver after the Induction of Portal Tolerance Depending on Donor-Recipient Differences in Rats. AB - Induction of donor-specific tolerance in outbred Wistar rats (RT1u) and inbred August rats (RT1c) increased the expression of immune proteasome subunits in liver with a peak on day 7 after beginning of the induction. The increase in the level of immune subunits LMP2 and LMP7 was more pronounced in the liver of August rats in comparison with Wistar rats (by 2 and 6 times, respectively), which was associated with higher concentrations of monoamines in the CNS of August rats. After induction of donor-specific tolerance in August and Wistar rats, the immune subunits were in cells of sinusoidal lining and in cells located in sinusoid lumens. It can be suggested that immune proteasomes in these cells producing antigenic peptides for presentation to immunocompetent participate in the suppression of their activity and form the molecular basis for the development of donor-specific tolerance at very early stages of this process. PMID- 29577194 TI - Cytokine Production by Splenic Cells in C57BL/6J Mice with Depression-Like Behavior Depends on the Duration of Social Stress. AB - We studied the influence of depression-like behavior developed in C57BL/6J mice under conditions of social stress of different duration on cytokine production by splenic cells. Imbalance of the pro- and anti-inflammatory cytokines was detected at the early stage of depression-like behavior (10-day experience of defeats): increased production of proinflammatory IL-2 and IL-6 cytokines along with a decrease in anti-inflammatory IL-10 level; the levels of IL-1beta, TNFalpha, IFNgamma, and IL-4 remained unaffected. At later terms (20 days of confrontations), we revealed more pronounced changes in spontaneous production of proinflammatory cytokines that were not detected after shorter social stress. These findings suggest that cytokine profile depends on duration of social stress. Possible mechanisms of cytokine production during formation of depression like state are discussed.

AB - Protein IGFBP6 plays an important role in the pathogenesis of many malignant tumors, including breast cancer. The relationship between IGFBP6 protein and the expression of genes associated with the epithelial-mesenchymal transition is studied. Gene IGFBP6 knockdown does not trigger the epithelial-mesenchymal transition in MDA-MB-231 cells, but modifies significantly the expression of many genes involved in this process. A decrease of IGFBP6 expression can involve a decrease in the expression of N-cadherin and transcription factor Slug. PMID- 29577196 TI - Modulation of GABA- and Glycine-Activated Ionic Currents with Semax in Isolated Cerebral Neurons. AB - The concentration-clamp experiments with neurons isolated from the rat brain showed that nootropic and neuroprotective drug Semax added to perfusion solution at concentration of 1 MUM augmented the amplitude of GABA-activated ionic currents in cerebellum Purkinje cells by 147+/-13%. In addition, Semax in perfusion solution (0.1 and 1 MUM) diminished the amplitude of glycine-activated chloride currents in hippocampal pyramidal neurons down to 68 and 43% control level, respectively. Both potentiating and inhibitory effects developed slowly, and they were poorly reversible, which indicated a probable implication of second messengers in the observed phenomena. Semax accelerated the falling edge of glycine-activated current both after a short-term co-application with agonist and after addition of this peptide into perfusion solution.

AB - In culture of THP-1 cells differentiated into macrophages with PMA (THP-PMA macrophages) infected with influenza viruses of subtypes H1, H5 and H9, we measured the expression of TLR7 and RIG1 receptor genes, sensors of viral RNA and ribonucleoprotein, and the levels of production of inflammatory cytokines IL 1beta, TNFalpha, IL-10, and IFNalpha. The sensitivity and inflammatory response of THP-PMA macrophages to pandemic influenza A virus H1N1pdm09 and avian influenza H5N2 and H9N2 viruses correlate with the intracellular level of their viral RNA and activation of the RIG1 gene. Abortive infection is accompanied by intensive macrophage secretion of TNFalpha, IL-1beta, and toxic factors inducing cell death. Activity of endosomal TLR7 receptor gene changed insignificantly in 24 h after infection and significantly decreased in 48 and 72 h under the action of H5N2 and H9N2, which correlated with manifestation of the cytopathogenic effect of these viruses. H5N2 and H9N2 avian viruses in THP-PMA macrophages are strong activators of the expression of the gene of the cytoplasmic RIG1 receptor 24 and 48 h after infection, and the pandemic virus H1N1pdm09 is a weak stimulator of RIG1 gene. Avian influenza H5N2 and H9N2 viruses are released by rapid induction of the inflammatory response in macrophages. At the late stages of infection, we observed a minor increase in IL-10 secretion in macrophages and, probably, the polarization of a part of the population in type M2. The studied influenza A viruses are weak inductors of IFN in THP-PMA macrophages. In the culture medium of THP-PMA macrophages infected with H9N2 and H5N2 viruses, MTT test revealed high levels of toxic factors causing the death of Caco-2 cells. In contrast to avian viruses, pandemic virus H1N1pdm09 did not induce production of toxic factors. PMID- 29577198 TI - Study of the Oxime-induced Reactivation of Acetyl- and Butyrylcholinesterase of Human with Inhibition of Organophosphorus Insecticide In Vitro. AB - The efficiency of different reactivators of cholinesterase (toxogonin, dipiroxime, pralidoxime, carboxim, HI-6, and methoxime) at inhibition of butyrylcholinesterase and human acetylcholinesterase by organophosphate insecticide malathion was evaluated in in vitro experiments. Most reactivators increased inhibition of butyrylcholinesterase in comparison with the control, but HI-6 in a concentration of 10-3 mol/liter partially (10%) restored activity of the enzyme. Oxime-induced reactivation of acetylcholinesterase was most pronounced in dipyroxime and toxogonin: parameters of the kinetics of reduction of the phosphorylated enzyme differed by more than 2 times from the values received with the use of other reactivators. PMID- 29577199 TI - Experimental Analysis of the Efficacy of Dihydroquercetin on the Model of Chronic Nonbacterial Inflammation of the Prostatic Gland. AB - We studied the efficiency of dihydroquercetin on the model of chronic nonbacterial inflammation of the prostatic gland in rats. It was found that administration of dihydroquercetin was followed by a significant decrease in the area of the connective tissue in the prostatic gland to initial levels, which attested to antifibrotic properties of this oxidant. Additionally, the substance prevented the development of atrophy of acinus epithelium. After administration of reference drug Prostamol Uno, only moderate antifibrotic effects were observed. PMID- 29577200 TI - Role of Copper Dyshomeostasis in the Pathogenesis of Parkinson's Disease. AB - Serum concentration of copper, immunoreactive polypeptides of ceruloplasmin and its oxidase activity, and the number of copper atoms per ceruloplasmin molecule were decreased in patients with Parkinson's disease in comparison with the corresponding parameters in age-matched healthy individuals, but the ratio of apoceruloplasmin to holoceruloplasmin in patients with Parkinson's disease was similar in both groups. Treatment of blood serum with Helex 100, a high-affinity copper chelator, revealed reduced content of labile copper atoms per ceruloplasmin molecule in patients with Parkinson's disease in comparison with that in healthy controls. The mechanism underlying impaired metabolic incorporation of labile copper atoms into CP molecule is discussed as a possible cause of copper dyshomeostasis associated with Parkinson's disease.

AB - We compared the effect of a new potential antidepressant 8-trifluoromethyl 1,2,3,4,5-benzopentathiepine-6-amine hydrochloride (TC-2153) and classical antidepressant fluoxetine in a dose of 0.25 mg/liter on the behavior of Danio rerio in the "novel tank" test and content of biogenic amines and their metabolites in the brain. Fluoxetine alone and TC-2153 alone significantly increased the time spent in the upper part of the tank and insignificantly reduced motor activity. Combined exposure of fishes in the solution containing potential and classical antidepressants potentiated their effects on both parameters. The compounds did not affect brain contents of serotonin, dopamine, and norepinephrine. At the same time, fluoxetine, but not TC-2153, reduced brain content of the main serotonin metabolite 5-hydroxyindole acetic acid. PMID- 29577202 TI - Compounds of IL-6 Receptor Complex during Acute Lung Injury. AB - Soluble receptor of IL-6 (sIL-6R) and antagonist of the receptor complex, soluble glycoprotein 130 (sgp130) mediate opposite effects during inflammation. We measured the levels of these cytokines and their ratio in rat blood on the model of acute lung injury. The injury was modeled by the intratracheal administration of LPS. The levels of sgp130 and sIL-6R increased during the inflammatory process in the injured lungs. The sgp130/sIL-6R ratio increased or decreased depending on the intensity of the inflammatory process. sgp130/sIL-6R ratio might reflect the intensity of inflammation during lung injury.

PMID- 29577204 TI - fMRI Responses in Healthy Individuals and in Patients with Mild Depression to Presentation of Pleasant and Unpleasant Images. AB - Patients with mild depression and apparently healthy individuals were presented images and asked to sort them into "pleasant" and "unpleasant" subsets. In both groups, the main differences between brain activation patterns during presentation of pleasant and unpleasant images were localized in the motor regions (precentral and postcentral gyrus) and in the cerebellum (p<0.05 with FWE correction). Most likely, these clusters are associated with motion (pressing a button in accordance with the instruction). According to the data of intergroup contrasts, patients with depression had less pronounced activation of frontal structures (middle frontal gyrus and other areas, including the white matter) in response to both positive and negative images (p<0.001). In healthy subjects, the response of the temporo-occipital areas (lingual and fusiform gyrus) to unpleasant stimuli was more intensive than in patients (p<0.001). This can be due to differences in the semantic image processing. Thus, in case of mild depression, the response of the amygdaloid complex, the key structure in the development in affective disorder, was not always observed. At the same time, the response of frontal and temporo-occipital regions has a certain potential as a biomarker of mild depression, although the reliability of the obtained data requires additional confirmation. PMID- 29577205 TI - Influence of "Enriched Environment" on Behavior and Neurogenesis in Mice Selected by Cognitive Trait. AB - Mice selected for high score in the extrapolation test (EX line) and kept under conditions of "enriched environment" for 3 months demonstrated changes in locomotor and exploratory activity and enhanced reaction to novelty. The relative brain weight was higher and neurogenesis in the hippocampal fascia dentate was more intensive in this group. In non-selected mice, the changes were similar, but insignificant in many cases. PMID- 29577206 TI - Stress Response to Physical Exercise in Rats with Alimentary Obesity. AB - Stress response to physical exercise was studied in rats with alimentary obesity with and without caloric diet restriction. Daily excretion of corticosterone, progesterone, and testosterone, weights of internal organs, and serum levels of glucose, free fatty acids, triglycerides, corticosterone, and testosterone were estimated. Stress response to moderate exercise in rats with alimentary obesity was associated with predominance of anabolic influence of testosterone over the catabolic effects of corticosterone, which promoted the increase in the weight of reproductive organs. Exposure to physical loads against the background of restricted ration potentiated the response of the adrenocortical system and reduced the concentration and anabolic effects of testosterone. PMID- 29577207 TI - Assessment of Cardiac Vegetative Control during Acute Graduated Exogenous Normobaric Hypoxia in Rats. AB - The effects of exogenous normobaric hypoxic hypoxia on vegetative control of the heart and BP were examined in Wistar rats. The reference ranges of variation pulsometry parameters were determined in rats with normoxemia for 3 physiological variants of autonomic homeostasis: eutony, sympathicotony, and vagotony. Most rats (80%) demonstrated autonomic eutony. The study showed that saturation of arterial blood with oxygen is the most adequate assessment of severity of acute exogenous normobaric hypoxic hypoxia progressing within a closed hypoxic chamber, which standardizes this method and minimizes inaccuracies resulting from individual sensitivity to hypoxic stress. The changes in functional activity of systems that control the heart rhythm closely correlated with the drop in arterial blood oxygenation. While a small arterial hypoxemia activated the ergotropic elements of autonomic nervous system central subdivision accompanied by elevation of systolic BP, the moderate hypoxemia augmented the cholinergic influences and moderated the adrenergic ones under maintaining mobilization of the central autonomic nervous system-control loop and normotension. Severe hypoxemia was manifested by augmented influences from autonomic nervous system central subdivisions on the heart rate, disadaptation of the control systems, and systolic-diastolic arterial hypotension. PMID- 29577208 TI - Hematopoietic Stem Cell Transplantation for Adult Philadelphia-Negative Acute Lymphoblastic Leukemia in the First Complete Remission in the Era of Minimal Residual Disease. AB - PURPOSE OF REVIEW: The purpose of this review is to discuss the potential role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for Philadelphia negative (Ph-) adult acute lymphoblastic leukemia (ALL) in first complete remission (CR1) in the era of minimal residual disease (MRD). RECENT FINDINGS: Allo-HSCT continues to have a role in the therapy of a selected group of high risk adult patients with ALL in CR1. Although the clinical significance of MRD has been studied less extensively in adults with ALL than in children, recent studies support its role as the strongest prognostic factor that can identify patients that are unlikely to be cured by standard chemotherapy and benefit from undergoing allo-HSCT. In addition, MRD status both pre- and post-HSCT has been found to correlate directly with the risk of relapse. Currently, the clinical challenge consists on applying MRD and molecular failure to integrate novel agents and immunotherapy to lower MRD before allo-HSCT and to modulate the graft versus leukemia (GVL) effect after transplant. PMID- 29577209 TI - [The necessary perseverance of surgery for the treatment of locally advanced colorectal cancer]. AB - Colorectal cancer, a malignant tumor arising from the colon or rectum, is a common cancer in China, with most patients diagnosed at the advanced stage or locally advanced stage. Large tumor size results in the invasion of adjacent organs and the multiple organ involvement, which poses certain challenges for clinical treatment. When facing advanced stage colorectal cancer, some surgeons do not consider surgery, a reasonable option. However, in fact, multi disciplinary treatment can achieve relatively good treatment outcomes in patients with advanced stage or locally advanced stage colorectal cancer. Therefore, reasonable surgery should not be hastily abandoned. For patients with large tumors without distant metastases but with multiple organ involvement, directly surgical resection is difficult, therefore, preoperative adjuvant therapy can be considered. The basic principle of surgical treatment is to accomplish maximum protection of organ functions and to perform reasonable regional lymph node dissection on the basis of achieving R0 resection. Common surgical procedures for locally advanced colorectal cancer are as follows: (1)Right-sided colon cancer with duodenal invasion: first, the colon must be freed from three directions, namely the right posterior surface of the colon, the left side of the tumor, and the upper side of the tumor inferior to the pylorus, so as to expose and assess the spatial relationship between the tumor and the duodenum; the actual tumor invasion depth in the duodenum may be shallow. (2) Splenic flexure colon cancer with invasion of the cauda pancreatis and hilum lienis: multivisceral resection must be performed without separating the attachment between the tumor and spleen. The tumor border can be found more easily through manipulations starting from the descending colon. (3) Giant sigmoid colorectal cancer with bladder invasion: invasion usually occurs at the bladder fundus. Therefore, during surgery, the attachment between the rectum and the bladder must not be separated first, but instead, an assessment must be made to determine if the bladder trigone is involved. (4) Rectal cancer with invasion of the sacrum: sacral invasion below S3 can be resected. The proximal end of the rectum to the point where it joins the sacrum is freed, and the rectum is severed. A permanent colostomy is made at the proximal end, while a h-shaped incision is made in the sacrum. The sacrum is then resected along pre-determined resection lines. (5) Rectal cancer with invasion of the uterus, adnexa, vagina, or prostate and seminal vesicles: it is usually observed in low rectal cancer. For unilateral ovarian involvement, combined resection of the bilateral adnexa should be performed. For vaginal involvement, combined resection of the vagina should be performed. For prostatic involvement, partial resection of the prostate can be performed. In general, when facing relatively complicated advanced or locally advanced colorectal cancer, clinical surgeons must adopt a positive attitude and strive zealously against the odds. With the support of multi-disciplinary treatment, the option of surgery must not be hastily abandoned in order to increase the survival chances of patients. PMID- 29577210 TI - [Transanal conformal resection for super low rectal cancer]. AB - Intersphincteric resection(ISR) is a valuable anus-preserving operation that avoids the need for permanent stoma in patients with super low rectal cancer. Recently, with the application and promotion of ISR, the rate of anus preservation has been greatly elevated, however, some patients following ISR had poor anal function. Based on the knowledge of anal canal anatomical features for better anal function, we propose conformal sphincter-preserving operation (CSPO) for super low rectal cancer, which is a new integrated anus-preservation procedure with total mesorectal excision (TME), coloanal anastomosis, pull through resection, anal canal dissection, local resection and natural orifice transluminal endoscopic surgery technology. CSPO includes pull through conformal resection (PTCR) and transanal conformal resection (TaCR). This article focuses on the problems about TaCR for very low rectal cancer and introduces TaCR combined with our practical experience. The indications for the TaCR operation should be according to the conventional laparoscopic surgery. In addition, the TaCR operation has its special indications: the tumor location is within 2 cm of the dental line; the tumor is well differentiation (moderately to well differentiation); the diameter of the tumor is not more than 3 cm or no more than the 1/3 circle of intestinal wall; and the depth of invasion is T1-T2. Patients with a clinical complete remission after neoadjuvant radiochemotherapy can receive TaCR. The laparoscopic five hole method is used to carry out the abdominal operation with TME technique. It is unnecessary to dissection intersphincter space. The incisional line is made according to the tumor location and shape to preserve the opposite normal rectal wall, internal sphincter and dentate line as more as possible via transanal resection. After closing the rectal stump by interrupted sutures, a circular stapler or hand suture is use to perform the anastomosis as far from the dentate line as possible. Protective loop ileostomy is performed. Postoperative complications, including anastomotic leakage, abdominal infection, and anastomotic bleeding, should be remembered. If there is any signs of these complications, intervention should be done as soon as possible. PMID- 29577211 TI - [Transanal total mesorectal excision for low rectal cancer: pros and cons]. AB - Colorectal cancer is the 3rd most commonly diagnosed cancer, with rectal cancer specifically accounting for 1/3 of new cases. Despite advances in care, there is still a lack of standardization in diagnosis, staging, and treatment, with associated high rates of positive margins, recurrence, and mortality. The gold standard for curative resection remains a total mesorectal excision(TME), and the quality of the TME is one of the most important prognostic factors for local recurrence. The proper TME specimen with negative resection margins is inherently challenging due to patient and tumour-related factors. These difficulties have not been overcome with the laparoscopic approach. Transanal TME (taTME) is an innovative surgical technique developed to overcome the limitations in exposure and instrumentation in low pelvic surgery by approaching the rectum from below. Interest in taTME continues to grow worldwide, and structured training programs and case registries have been developed to aid safe implementation of this new technique in clinical practice. As the utilization of taTME and indications for the procedure continue to expand, structured programs to standardize teaching, training, and safe expansion will aid the safe spread of the taTME technique. With the growing popularity, a review of the pros and cons of the taTME is timely. PMID- 29577212 TI - [Associated vessel heteromorphosis in laparoscopic complete mesocolic excision and solutions to intraoperative hemorrhage]. AB - Vessel identification and dissection are the key processes of laparoscopic complete mesocolic excision (CME). Vascular injury will lead to complications such as prolonged operative time, intraoperative hemorrhage and ischemia of anastomotic stoma. Superior mesenteric artery (SMA), superior mesenteric vein(SMV), gastrointestinal trunk, left colic artery(LCA), sigmoid artery and marginal vessels in the mesentery have been found with possibility of heteromorphosis, which requires better operative techniques. Surgeons should recognize those vessel heteromorphosis carefully during operations and adjust strategies to avoid intraoperative hemorrhage. Preoperative abdominal computed tomography angiography(CTA) with three-dimensional reconstruction can find vessel heteromorphosis within surgical area before operation. Adequate dissection of veins instead of violent separation will decrease intraoperative bleeding and be helpful for dealing with the potential hemorrhage. When intraoperative hemorrhage occurs, surgeons need to control the bleeding by simple compression or vascular clips depending on the different situations. When the bleeding can not be stopped by laparoscopic operation, surgeons should turn to open surgery without hesitation. PMID- 29577213 TI - [Key vessels assessment and operation highlights in laparoscopic extended right hemicolectomy]. AB - Laparoscopic radical colectomies have been more widely used gradually, among which laparoscopic extended right hemicolectomy is considered as the most difficult procedure. The difficulty of extended right hemicolectomy lies in the need to dissect lymph nodes along the superior mesenteric vein (SMV) and disconnect numerous and possible aberrant vessels. To address this problem, we emphasize two points in key vessel assessment: getting familiar with the anatomy along the medial-to-lateral approach and having a good understanding about the preoperative imaging presentations. An accurately preoperative imaging assessment by abdominal enhanced CT can help the surgeon understand the relative position of the key vessels to be dealt with during operation and the situation of the possible aberrant vessels so as to guide the procedure more effectively and facilitate the prevention and management of the intraoperative complications. During operation, the operator should pay special attention to the management of the vessels in the ileocolic vessel region, Henle's trunk and middle colon vessels. The operation highlights of the key vessels are as follows: (1) The ileocolic vessels: identifying the Toldt's gap correctly and opening the vascular sheath of the SMV securely; making sure that the duodenum is well protected. (2) Henle's trunk: dissecting along the surface of the Henle's trunk; preserving the anterior superior pancreaticoduodenal vein (ASPDV) and main trunk of the Henle's trunk; disconnecting the roots of the right colic vein (RCV) and right gastroepiploic vein (RGEV), and then dissecting lymph nodes along the surface of the pancreas. (3) The middle colon vessels: identifying the root of the middle colon vessel along the lower edge of the pancreas; avoiding entering behind the pancreas; mobilizing the transverse mesocolon sufficiently along the surface of the pancreas. Finally, we discuss and analyze the disputes currently existing in laparoscopic extended right hemicolectomy, including dissection of No.6 lymph nodes, naking the SMA and dissecting lymph nodes around the roots of the branches of SMA. This article shares our experience about laparoscopic extended right hemicolectomy, hoping that it could help beginners master the technique more safely and skillfully. PMID- 29577214 TI - [Significance of the preservation of left colic artery in laparoscopic resection of rectal cancer]. AB - Controversy remains on how to manage left colic artery (LCA) when it comes to laparoscopic proctectomy. With regard to the level of detachment, a high tie of inferior mesenteric artery (IMA) is meant as a ligation at the origin of aorta, while the low tie is the ligation of IMA below the initiation part of left colic artery which is left. Several key points of LCA preservation, including clinical value, oncologic safety and the difficulty of operation, have always been debated. Some scholars hold the point of view that the preservation of LCA will hamper the lymph nodes dissection around the inferior mesenteric artery, resulting in incorrect pathological staging and dismal outcome. Of note, low tie prolongs the duration of operation and increases the anastomotic tension. However, increasing research results have established its clinical values. The value for reducing the risk of anastomotic leakage and the effect on the lymph nodes dissection at the root of inferior mesenteric artery will be discussed based on previous studies and our clinical practice. We came up with a novel concept of "the lymph nodes in the triangular domain of inferior mesenteric artery which consists of abdominal aorta, inferior mesenteric vein(IMV)/LCA and IMA" instead of traditional No.235 lymph nodes. In our innovative approach of total mesorectal excision guided by vessel, a crack was made at the root of aorta and the dissection was performed along IMA, reaching the origin of LCA. The lymph nodes will be harvested as a whole. After achieving process standardization, vessel-oriented approach and left colic artery preservation makes this region susceptible to lymphadenectomy, protecting submesenteric plexus and guarantying the oncological safety without increasing operative difficulty. PMID- 29577215 TI - [Current status in surgical treatment of constipation]. AB - Chronic constipation is a polysymptomatic heterogeneous disorder with the incidence rising in many countries, and becomes a common disease affecting the quality of life and financial burden. In China surgical guideline, the primary constipation is divided into 3 types: slow transit constipation, outlet obstructive constipation, mixed constipation. The Rome IIII( criteria is usually referred to diagnosis, considering with clinical features and patient complaints. Through detail interrogation, physical examination and various detections, the secondary causes should be excluded, and etiological treatment is worth to try. Surgery is generally recommended as the second-line therapy, and finally only few patients require operation. There are still several controversies over the choice of surgical procedures and the mode of anastomosis in patients with slow transit constipation. Common surgical procedures include total colectomy with ileorectal anastomosis (TAC-IRA), subtotal colectomy with ileosigmoid anastomosis, ileorectal anastomosis or cecal-rectal anastomosis. Now laparoscopic operations have been widely applied to these patients, and have achieved good efficacy, and the application of robots is also under exploration. With the outlet obstructive constipation complicated pathogeny, the mechanisms currently involved include paradoxical puborectalis contraction, increased perineal descent, rectal intussusception, rectocele and rectal prolapse. In recent years, aiming at the above mechanisms, variety of surgical methods has been explored, including bilateral partial resection of puborectalis (PDPR) for paradoxical puborectalis contraction, rectal mucosa longitudinal plication plus sclerosing agent injection, procedure for prolapse and hemorrhoids (PPH), rectal mucosal resection and muscle plication procedure (Delorme), stapled transanal rectal resection (STARR) and laparoscopic ventral mesh rectopexy (LVR) etc for rectal prolapse. However, there is still no long-term large sample study to prove the advantages and disadvantages of these operations, so operative procedure should be chosen according to the actual situation of the patient. With the integration of the pathogenesis and the diversification of the treatment methods, the constipation still needs the precise treatment combined with multidisciplinary support in the future. PMID- 29577216 TI - [Application of inner figure-of-eight suture to laparoscopic colorectal surgery]. AB - Regardless of laparoscopic or open colorectal surgeries, intestinal anastomosis is usually an important operative procedure. Even if stapler is widely used in different intestinal surgery nowadays, hand sewn suture is an indispensable procedure in clinical practice, meanwhile after stapled anastomosis, additional hand sewn suture is usually performed to ensure the safety of anastomosis. The inner figure-of-eight suture is a single layer suture technique which has been widely used in skin, tendon, rectus and uterus for quick and secure approximation. We describe our innovative application of inner figure-of-eight suture technique for intestinal anastomosis and/or reinforcement after stapled anastomosis in laparoscopic colorectal surgery. Main steps of inner figure-of eight suture for intestinal anastomosis on posterior wall are as follows: (1) At 4 mm from cut edge of bowel, needle enters vertically from one side and courses mucosa-serosa-opposite serosa-mucosa in parallel to the entry point. (2) The needle is brought back to first entry side of bowel at 45 degree to enter the mucosa 5 mm below the first entry point and out on opposite side mucosa horizontally. (3) Both lose ends of the suture are pulled to approximate bowel edges and knots are tied on mucosal surface, in which suture line presents figure of-eight on mucosal surface and two parallel suture lines are seen on serosal surface. When inner figure-of-eight suture is performed on anterior wall, the procedure is similar, but needle passes from serosa-mucosa-opposite mucosa-serosa and repeated to complete the inner figure-8 suture and knots are tied on serosa. The final look is two parallel sutures at 0.5 mm in between and the figure-of eight remains inside the lumen. We did not deliberately try to invert the bowel edges, and if anastomosis is not satisfactory at final examination, simple interrupted seromuscular suture can be carried out. From 2015 till now, we have successfully completed inner figure-of-eight sutures in 38 cases receiving intestinal anastomosis reinforcement procedure and in 24 cases receiving hand sewn anastomosis. Comparison study revealed inner figure-of-eight suture presented shorter anastomotic time and less medical cost without anastomotic leakage, stump leakage or bleeding. No anastomotic stenosis was found at enteroscopy examination during follow up. We think that inner figure-of-eight suture possesses safe and simple advantages and is a manual suture technique worthy of promotion. PMID- 29577217 TI - [Impact of previous abdominal surgery on the outcomes of laparoscopic resection for colorectal cancer]. AB - OBJECTIVE: To investigate the effect of previous abdominal surgery(PAS) on laparoscopic resection of colorectal cancer. METHODS: The retrospective cohort study was adopted.Clinical data of consecutive colorectal cancer patients with PAS history (past history of at least one abdominal surgery, exclusion of previous inguinal hernia repair, simple laparoscopic approach, appendectomy of the right lower quadrant and endoscopic therapy) undergoing laparoscopic surgery at the Cancer Hospital of Chinese Academy of Medical Sciences between 2010 and 2015 were collected, meanwhile other colorectal cancer patients without PAS history were selected according to 1 to 1 match in age, sex, body mass index, American Society of Anesthesiologists score, tumor location, type of surgery, and staging of tumor. A total of 464 pairs were successfully matched. Intraoperative and postoperative conditions, perioperative complications and prognosis were compared between the two groups. RESULTS: In PAS group, there were 341 males (73.5%) and 123 females (26.5%) with a median age of 62 (24-85) years; 317(68.3%) cases with only one previous abdominal surgery and 147(31.7%) with more than one; 389(83.8%) cases with abdominal midline incisions, 37(8.0%) with transverse incisions, 34(7.3%) with right subcostal incision and 4(0.9%) with left subcostal incision; 146(31.5%) cases undergoing gynecologic surgery, 84(18.1%) cholecystectomy, 52(11.2%) gastroduodenal surgery, 89(19.2%) colorectal surgery, 11(2.4%) small intestine surgery, 23(5.0%) hapatectomy, 16(3.4%) pancreatic surgery, 8(1.7%) urological surgery, 18(3.9%) retroperitoneal tumor resection and 1(0.2%) other surgery. In no PAS group, there were 328 males (70.7%) and 136 females (29.3%) with a median age of 62(24-86) years. No significant differences in baseline data were found between the two groups (all P>0.05). As compared to no PAS group, PAS group had longer mean operative time [(208.0+/-27.0) minutes vs. (179.0+/-15.3) minutes, t=4.695, P=0.003] and higher rate of conversion to laparotomy [18.1%(84/464) vs. 11.6%(54/464), chi2=7.217, P=0.003]. In the PAS group, conversion to laparotomy was more common due to adhesion reaction [8.8%(41/464) vs. 4.5%(21/464), chi2=4.886, P=0.007]. There were no significant differences between the two groups in intraoperative bleeding and transfusion, lymph node dissection, circumferential margin and surgical margin, time to the first diet and postoperative hospital stay(all P>0.05). No significant differences in intraoperative and postoperative morbidity of complication were found between PAS group and no PAS group [3.7%(17/464) vs. 2.8%(13/464), P=0.346; 20.3%(94/464) vs. 18.5%(86/464), P=0.739]. Median follow-up of the whole patients was 32.0(0.5-79.0) months, and there was no significant difference between the two groups [PAS group 31.0(0.5-79.0) months vs. no PAS group 33.0(1.0-75.0) months, P=0.391]. In PAS and no PAS group, the 3-year disease-free survival rate was 68.1%(95%CI: 62.0%-74.2%) and 68.5%(95%CI: 63.0%-74.0%)(P=0.764), and 3-year overall survival rate was 78.5%(95%CI: 72.8%-81.4%) and 80.2%(95%CI:74.3% 86.1%)(P=0.528) respectively, whose differences were not significant. CONCLUSION: Except higher risk of conversion to laparotomy due to adhesion reaction, laparoscopic resection of colorectal cancer is safe and feasible in patients with PAS, and the prognosis is not affected by PAS. PMID- 29577218 TI - [Application of Overlap method to digestive tract reconstruction of totally laparoscopic left colectomy]. AB - OBJECTIVE: To investigate the application value of the Overlap method in digestive tract reconstruction of totally laparoscopic left colectomy(TLLC) and its potential advantage. METHODS: The retrospective cohort study was adopted. Clinicopathological data of 16 patients with left colon cancer who underwent TLLC and Overlap anastomosis between August 2016 and August 2017 at Tangdu Hospital were retrospectively collected as Overlap group. Twenty-one patients who underwent laparoscopic assisted left colectomy (LALC) between January 2015 and July 2016 at Tangdu Hospital were used as control (traditional group). The intraoperative and postoperative data were compared between the two groups. During digestive tract reconstruction in the Overlap group, the proximal colon and distal colon were lined up side by side; a side-to-side anastomosis was conducted on colic band with a 60 mm linear stapler; and the common entry hole was closed using running suture. While in traditional group, the bowel was pulled out of abdominal wall through the assisted incision; the sample was resected and a proximal and distal end-to-end anastomosis was performed. RESULTS: In Overlap group, 10 cases were male and 6 cases were female, with a mean age of (66.4+/ 4.8) years and a BMI of (23.6+/-2.3) kg/m2; the tumor located in distal transverse colon in 1 case, in splenic flexure in 2 cases, in descending colon in 4 cases, in upper sigmoid colon in 9 cases. TLLC was successfully completed in all the cases without conversion to laparotomy. In traditional group, 12 cases were male and 9 cases were female, with mean age of (65.9+/-5.8) years and BMI of (22.7+/-2.8) kg/m2; the tumor located in the distal transverse colon in 1 case, in the splenic flexure in 3 cases, in the descending colon in 6 cases, in the upper sigmoid colon in 11 cases. No statistically significant differences in baseline data were found between the two groups (all P>0.05). Compared to the traditional group, the total operation time was shorter [(143.4+/-11.1) minutes vs. (166.4+/-16.5) minutes, t=4.792, P=0.000], the anastomosis time was prolonged [(44.3+/-3.3) minutes vs. (22.4+/-3.0) minutes, t=-20.948, P=0.000], the amount of bleeding was reduced [(46.6+/-13.6) ml vs. (70.5+/-20.0) ml, t=4.106, P=0.000], and the incision length was shorter [(3.9+/-0.9) cm vs. (6.7+/-1.3) cm, t=7.056, P=0.000] in the Overlap group. There were no significant differences in lymph nodes harvested (17.3+/-2.9 vs. 15.5+/-3.0), time to flatus [(2.8+/-1.3) days vs. (2.6+/-1.0)days], postoperative complications [6.2%(1/16) vs. 9.5%(2/21)] and postoperative hospitalization [(4.6+/-1.4) days vs.(4.7+/-1.2) days] between the two groups (all P>0.05). CONCLUSION: The Overlap reconstruction method in totally laparoscopic left colectomy is a safe and feasible procedure, and provides less injury and better cosmetic outcome of abdominal wall.

AB - OBJECTIVE: To compare the surgical safety and short-term efficacy of minilaparotomy and laparoscopic approach for curative resection of rectal cancer. METHODS: The retrospective cohort study was adopted. A review of patients scheduled to undergo a curative resection of rectal cancer via minilaparotomy or laparoscopic approach at Department of Colorectal Surgery of Changhai Hospital from June 2016 to May 2017 was carried out. All the patients were confirmed as rectal cancer by postoperative pathology. The following patients were excluded from the study: patients who had acute complete obstruction or perforation; patients underwent Miles or Hartmann procedure; patients who required an elongation of the skin incision in minilaparotomy or a conversion from laparoscopic to open surgery. Finally, 216 patients were enrolled in this study, of whom 143 were performed with minilaparotomy approach (minilaparotomy group) and 73 with laparoscopic approach (laparoscopic group) for curative resection of rectal cancer. For the minilaparotomy technique, a 7 cm longitudinal midline incision was made between the pubic symphysis and umbilicus; a wound retractor was applied to the edge of the wound; lymph node dissection around the inferior mesenteric and artery high ligation of inferior mesenteric artery were performed; by moving the minilaparotomy wound laterally and caudad or cephalad with the S shaped hook, cautious mobilization of the relevant segment of the bowel loop was performed; bowel anastomosis was achieved by using the double-stapled technique; the gap of the pelvic floor peritoneum and mesentery were routinely closed by the absorbable surgical suture in cases with middle and low position rectal cancer. The surgical safety, the condition of resuming and the morbidity of postoperative complication were compared between the two groups. RESULTS: There were 145 men and 71 women. Age ranged from 26 to 87 years, with of mean age of 61 years. According to the TNM stage grouping, there were 61 patients with stage I(, 62 with stage II(, 85 with stage III(, and 8 with stage IIII( disease, respectively. These two groups did not differ significantly in terms of age, sex, body mass index, site of tumor, TNM stage(all P>0.05). All the patients completed the operation successfully. The median operation time of minilaparotomy group was significantly shorter than that of laparoscopic group [164(80-296) minutes vs. 230(90-665) minutes, Z=4.410, P=0.000]. The intraoperative medical consumable expense [11000(7000-22000) yuan vs. 23000(12000-47000) yuan, Z=11.759, P=0.000] and the total hospitalization expense [44000(22000-146000) yuan vs. 57000(45000 126000) yuan, Z=9.637, P=0.000] were significantly lower in the minilaparotomy group. There were no significant differences between the two groups in terms of operative blood loss, number of harvested lymph nodes, distance of distal resection margin, positive rate of circumferential resection margin (all P>0.05). The rate of postoperative complication in minilaparotomy group was 7.0%(10/143) and in laparoscopic group was 9.6%(7/73) without significant difference (chi2=0.449, P=0.503). There were 2 patients in each group who required readmission to the hospital within postoperative 30 days. The cause of readmission was ileus or acute hyponatremia in minilaparotomy group, and ileus or pevic infection in laparoscopic group. One patient died of brain death caused by acute pulmonary embolism during the perioperative period in minilaparotomy group. CONCLUSIONS: The minilaparotomy approach for curative resection of rectal cancer is safe and feasible. As compared with laparoscopic approach, it is advantageous to achieve minimal invasiveness and early recovery, but much cheaper and less time consuming.

AB - OBJECTIVE: To compare the short-term safety and costs between laparoscopic assisted or totally laparoscopic uncut Roux-en-Y and Billroth II((BII() + Braun reconstruction after radical gastrectomy of distal gastric cancer. METHODS: Clinical data from our prospective database of radical gastrectomy were systematically analyzed. The patients who underwent laparoscopic gastrectomy with uncut Roux-en-Y or BII(+ Braun reconstruction between March 1st, 2015 and June 30th, 2017 were screened out for further analysis. Both the reconstructions were completed by linear staplers. Uncut Roux-en-Y reconstruction was performed with a 45 mm no-knife linear stapler (ATS45NK) on the afferent loop below the gastrojejunostomy. Continuous variables were compared using independent samples t test or Mann-Whitney U. The frequencies of categorical variables were compared using Chi-squared or Fisher exact test. RESULTS: Eighty-one patients were in uncut Roux-en-Y group and 58 patients were in BII(+Braun group. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in median age (56.0 years vs. 56.5 years, P=0.757), gender (male/female, 52/29 vs. 46/12, P=0.054), history of abdominal surgery (yes/no, 10/71 vs. 4/54, P=0.293), neoadjuvant chemotherapy (yes/no, 21/60 vs. 11/47, P=0.336), BMI (thin/normal/overweight/obesity, 2/49/26/3 vs. 3/39/14/2, P=0.591), NRS 2002 score (1/2/3/4, 58/15/5/3 vs. 47/5/3/3, P=0.403), pathological stage (0/I(/II(/III(, 3/41/20/17 vs. 1/28/13/16, P=0.755), median tumor diameter in long axis (2.5 cm vs. 3.0 cm, P=0.278), median tumor diameter in short axis (2.0 cm vs. 2.0 cm, P=0.126) and some other clinical and pathological characteristics. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in morbidity of postoperative complication more severe than grade I([12.3% (10/81) vs. 17.2% (10/58), P=0.417], morbidity of anastomotic complication [1.2%(1/81) vs. 0, P=1.000] or hospitalization costs [(94000+/ 14000) yuan vs.(95000+/-16000) yuan, P=0.895]. The median first time to liquid diet (57.1 hours vs. 70.8 hours, P=0.017) and median postoperative hospital stay (9 days vs. 11 days, P=0.003) of the patients in uncut Roux-en-Y group were shorter than those in BII(+Braun group. CONCLUSION: Laparoscopic assisted or totally laparoscopic uncut Roux-en-Y reconstruction after radical gastrectomy of distal gastric cancer is safe and feasible with better recovery than BII(+Braun reconstruction. PMID- 29577221 TI - [Application of robotic and laparoscopic radical total gastrectomy to gastric cancer patients with body mass index >=24 kg/m2]. AB - OBJECTIVE: To compare the short-term outcomes between robotic and laparoscopic radical total gastrectomy in gastric cancer patients with BMI index >=24 kg/m2. METHOD: Clinical data of 93 gastric cancer patients who underwent robotic and laparoscopic radical total gastrectomy at PLA General Hospital from April 2016 to April 2017 were retrospectively analyzed. The retrospective cohort study was adopted. INCLUSION CRITERIA: preoperatively definite diagnosis of primary gastric cancer by endoscopy and biopsy; preoperative BMI >=24 kg/m2; no previous abdominal surgery; no previous chemotherapy and radiotherapy; no distant metastasis or invasion into adjacent organs before operation or during operation; receiving radical gastrectomy; Roux-en-Y reconstruction of digestive tract in open procedure. According to approaches of minimally invasive surgery, 24 patients underwent robotic surgery and 69 underwent laparoscopic surgery. The intraoperative parameters (overall operative time, pneumoperitoneal time, open procedure time, intraoperative blood loss, transfusion rate, number of total retrieved lymph nodes and metastatic lymph nodes) and postoperative parameters (drainage in the first postoperative day, the first defecation time, morbidity of postoperative complication and hospital stay) were compared between two groups. Correlation of the above parameters were analyzed. RESULTS: Of 93 patients, 77 were male and 16 female with an average age of (60.0+/-10.6) years. The average BMI was (26.8+/-1.3) kg/m2 in whole patients, (26.9+/-1.6) kg/m2 in robotic group and (26.8+/-1.7) kg/m2 in laparoscopic group. No significant differences in age, gender, BMI, preoperative ASA class, postoperative pathological findings and clinical classification were observed between two groups, which made short-term parameters between two groups comparable. The robotic group had a significantly longer overall operative time [(301.2+/-68.9) minutes vs. (247.3+/-59.6) minutes, P=0.000], longer open procedure time [(141.5+/-26.3) minutes vs. (92.5+/-36.7) minutes, P=0.029] and higher cost than laparoscopy group[(17.5*104 +/- 9.7*104) yuan vs. (10.0*104 +/- 2.3*104) yuan, P=0.001]. Pneumoperitoneal operative time, intraoperative blood loss, transfusion rate, number of total retrieved lymph nodes, number of harvested metastatic lymph nodes and postoperative short-term efficacy were similar between the two groups (all P>0.05). In robotic group, pneumoperitoneal operative time was positively correlated with overall operative time (r=0.708, P=0.010); total cost was positively correlated with postoperative hospital stay (r=0.493, P=0.000) and open procedure time was negatively correlated with the first defecation time (r=-0.962, P=0.038). In laparoscopy group, total cost was positively correlated with overall operative time (r=0.411, P=0.046), drainage volume in the first postoperative day was positively correlated with the number of total dissected lymph node (r=0.540, P=0.006), postoperative hospital stay was positively correlated with intraoperative blood loss (r=0.574, P=0.003), total cost was positively correlated with intraoperative blood loss and hospital stay (r=0.609, P=0.002; r=0.865, P=0.000), drainage volume in the first postoperative day was positively correlated with BMI (r=0.533, P=0.007). CONCLUSION: For gastric cancer patients with BMI >=24 kg/m2, robotic radical total gastrectomy is associated with longer operative time and higher cost, but is less vulnerable to the change of BMI and more in favor of the realization of enhanced recovery after surgery (ERAS) than laparoscopic radical total gastectomy. PMID- 29577222 TI - [Establishment of comprehensive prediction model of acute gastrointestinal injury classification of critically ill patients]. AB - OBJECTIVE: To develop the comprehensive prediction model of acute gastrointestinal injury (AGI) grades of critically ill patients. METHODS: From April 2015 to November 2015, the binary channel gastrointestinal sounds (GIS) monitor system which has been developed and verified by the research group was used to gather and analyze the GIS of 60 consecutive critically ill patients who were admitted in Critical Care Medicine of Chinese PLA General Hospital. Also, the AGI grades (Grande I(-IIII(, the higher the level, the heavier the gastrointestinal dysfunction) were evaluated. Meanwhile, the clinical data and physiological and biochemical indexes of included patients were collected and recorded daily, including illness severity score (APACHE II( score, consisting of the acute physiology score, age grade and chronic health evaluation), sequential organ failure assessment (SOFA score, including respiration, coagulation, liver, cardioascular, central nervous system and kidney) and Glasgow coma scale (GCS); body mass index, blood lactate and glucose, and treatment details (including mechanical ventilation, sedatives, vasoactive drugs, enteral nutrition, etc.) Then principal component analysis was performed on the significantly correlated GIS (five indexes of gastrointestinal sounds were found to be negatively correlated with AGI grades, which included the number, percentage of time, mean power, maximum power and maximum time of GIS wave from the channel located at the stomach) and clinical factors after standardization. The top 5 post-normalized main components were selected for back-propagation (BP) neural network training, to establish comprehensive AGI grades models of critically ill patients based on the neural network model. RESULTS: The 60 patients aged 19 to 98 (mean 54.6) years and included 42 males (70.0%). There were 22 cases of multiple fractures, 15 cases of severe infection, 7 cases of cervical vertebral fracture, 7 cases of aortic repair, 5 cases of post-toxicosis and 4 cases of cerebral trauma. There were 33 emergency operation, 10 cases of elecoperectomy and 17 cases of drug treatment. There were 56 cases of diabetes(93.3%). Forty-five cases (75.0%) used vasoactive drugs, 37 cases (61.7%) used mechanical ventilation and 44 cases (73.3%) used enteral nutrition. APACHE II( score were 4.0 to 28.0(average 16.8) points. Four clinical factors were significantly positively related with AGI grades, including lactic acid level (r=0.215, P=0.000), SOFA score (r=0.383, P=0.000), the use of vascular active drugs (r=0.611, P=0.000) and mechanical ventilation (r=0.142, P=0.014). In addition to the five indexes of gastric bowel sounds which were found to be negatively correlated with AGI grades, the characteristics of 333 by 9 were composed of these nine indexes with high correlation of AGI grades. Five main components were selected after principal component analysis of these nine correlated indexes. A comprehensive AGI grades model of critically ill patients with a fitting degree of 0.967 3 and an accuracy rate of 82.61% was built by BP artificial neural network. CONCLUSION: The comprehensive model to classify AGI grades with the GIS is developed, which can help further predicting the classification of AGI grades of critically ill patients. PMID- 29577223 TI - [Effect of neoadjuvant chemotherapy on nutritional status of locally advanced gastric cancer]. AB - OBJECTIVE: To study the effect of neoadjuvant chemotherapy on nutritional status in patients with locally advanced gastric cancer. METHODS: Cases inclusion criteria: (1)18-65 years old; (2) Gastric cancer confirmed by gastroscopic biopsy; (3) Preoperative TNM stage III( according to the AJCC stage 2000 standard; (4) Kamosfsky functional status score> 60 points; (5)Receiving neoadjuvant chemotherapy voluntarily and signing the informed consent form. Case exclusion criteria: (1)Having contraindications of chemotherapy and surgery; (2) Suffering from heart, liver and kidney and other underlying diseases; (3) Concurrent with malignant diseases, wasting disease or other digestive diseases. According to the above criteria, clinical data of 73 patients of stage III( gastric cancer receiving neoadjuvant chemotherapy at Weifang People's Hospital from May 2015 to March 2017 were prospectively collected. The cohort study was adopted. After removing 3 patients who did not complete the chemotherapy, a total of 70 patients who completed the chemotherapy were included in the study. All the patients received SOX chemotherapy without nutritional support during chemotherapy. Changes of body composition and nutritional indicators were analyzed before and after chemotherapy, and according to the tumor regression after chemotherapy, patients were divided into response group (complete or sub total tumor regression) and non-response group (tumor part, with or without a small amount of retreat) for stratified analysis. RESULTS: Of 70 gastric cancer patients, 40 were male and 30 were female with a age of (53.8+/-6.4) (28 to 64) years. There were 26 cases (37.1%) of stage III(a, 35 cases (50.0%) of stage III(b and 9 cases (12.9%) of stage III(c. There were 41 cases in response group and 29 cases in non-response group. Three patients (4.3%) were complete remission (CR) and 38 patients (54.3%) were partial remission (PR) in response group, while 23 cases (32.9%) were stable disease (SD) and 6 cases (8.6%) were progressive disease (PD). After neoadjuvant chemotherapy, the extracellular fluid of the whole patients increased from (13.3+/-1.7) L to (13.5+/-1.6) L (t=-2.044, P=0.045); the intracellular fluid decreased from (21.4+/-2.5) L to (21.1+/-2.4) L (t=2.369, P=0.021); the lymphocyte count decreased from (0.31+/-0.10)*109/L to (0.29+/-0.10)*109/L (t=1.706, P=0.009); the other indexes were not significantly different (all P>0.05). Stratified analysis showed that after neoadjuvant chemotherapy in response group, body mass increased from (60.1+/-8.8) kg to (61.0+/-8.3) kg (t=-2.773, P=0.008); body mass index increased from (21.9+/-2.4) kg/m2 to (22.3+/-1.9) kg/m2(t=-3.479, P=0.001), while above two parameters did not differ significantly in non-response group. No significant differences in body mass, body mass index, skeletal muscle, inorganic salt, extracellular fluid, body fat, protein, upper arm circumference and intracellular fluid were found between two groups before and after neoadjuvant chemotherapy(all P>0.05). Except slight decrease in hemoglobin and lymphocyte, the other nutritional indicators were slightly elevated in response group, while the differences were not statistically significant(all P>0.05). All nutritional indicators in non-response group were slightly decreased without significant differences as well (all P>0.05). CONCLUSION: Neoadjuvant chemotherapy does not aggravate malnutrition in patients with locally advanced gastric cancer. PMID- 29577224 TI - [Relationship between the expression of DDX39 protein and prognosis of colorectal cancer]. AB - OBJECTIVE: To investigate the relationship between the expression of DDX39 protein and prognosis in colorectal cancer. METHODS: Clinical data and paraffin specimens of postoperative tumor tissue from 824 patients with primary colorectal cancer who received first surgical treatment at the Department of Colorectal Surgery of Changhai Hospital of Navy Military Medical University from January 2010 to December 2011 were collected. Paraffin samples of paracancerous tissues of 38 patients were served as controls. At the same time, samples of normal rectal mucous membrane from 37 cases after procedure of prolapse and hemorrhoids, and samples of colorectal adenoma from 33 cases after endoscopic treatment were enrolled in this study. All the specimens were made as the tissue microarray, and the expression of DDX39 protein was detected by immunohistochemistry. The expression of DDX39 in the epithelium and stroma was evaluated with the average staining intensity (H-Score) and the number of positive cells. It was defined as high expression in the epithelium that the H-Score was greater than or equal to 200. It was defined as high expression in the stroma that the number of positive cells was greater than or equal to 50 in 200 times the field of vision. Relationship of different DDX39 expression levels with clinicopathological parameters and prognosis of colorectal cancer was analyzed. RESULTS: The expression of DDX39 in colorectal cancer tissues was lower than that in normal tissues, paracancerous tissues and adenomatous tissues, whether it is in the epithelium or in the stroma [DDX39 expression in the epithelium: normal tissues 253.2+/-64.1, paracancerous tissues 238.8+/-79.2, adenomatous tissues 259.4+/ 51.6, colorectal cancer tissues 194.2+/-76.5 (P=0.000, P=0.005, P=0.000, respectively); DDX39 expression in the stroma: normal tissues 110.1+/-64.8, paracancerous tissues 106.0+/-49.2, adenomatous tissues 108.5+/-79.1, colorectal cancer tissues 54.1+/-34.7(all P=0.000)]. Among the cases of colorectal cancer, there were 541 cases of high DDX39 expression and 283 cases of low DDX39 expression in the epithelium; there were 424 cases of high DDX39 expression of and 400 cases of low DDX39 expression in the stroma. The high DDX39 expression and low DDX39 expression in epithelial and stromal of colorectal cancer were related respectively with tumor location (P=0.006, P=0.016), degree of tumor differentiation (P=0.002, P=0.064), TNM stage (P=0.021, P=0.000), serum CEA level (P=0.003, P=0.005), serum CA199 level (P=0.040, P=0.005) and tumor recurrence and metastasis (P=0.000, P=0.000). All the colorectal cancer cases were followed up for (41.6+/-15.7) months after operation. The 5-year overall survival (OS) and disease-free survival (DFS) rates of the cases with epithelial low DDX39 expression were 84.1% and 61.5%, and both were significantly lower as compared to those with epithelial high DDX39 expression (95.4% and 88.2%, P=0.000, P=0.000). The 5-year OS and DFS rates of the stroma low DDX39 expression were 86.8% and 66.8%, and both were significantly lower as compared to those with stroma high DDX39 expression (96.1% and 90.6%, P=0.000, P=0.000). Cox multivariate analysis showed that tumor differentiation (OS:HR=0.252, 95%CI: 0.128 to 0.497, P=0.000; DFS:HR=0.266, 95%CI: 0.134 to 0.530, P=0.000), DDX39 expression level in epithelium (OS: HR =0.229, 95%CI: 0.138 to 0.382, P=0.000; DFS: HR =0.266, 95%CI: 0.158 to 0.446, P=0.000), and DDX39 expression level in stroma (OS: HR =0.331, 95%CI: 0.188 to 0.582, P=0.000; DFS:HR=0.326, 95%CI: 0.184 to 0.578, P=0.000) were independent influencing factors of overall or disease-free survival in patients with colorectal cancer. CONCLUSION: The low expression of DDX39 protein suggests poor prognosis and DDX39 is expected to be a new prognostic marker of colorectal cancer. PMID- 29577225 TI - [Progress in the treatment of surgical procedures for slow transit constipation]. AB - Slow transit constipation (STC) is the most common type of chronic constipation, and surgical treatment is one of the most important means for the treatment of slow transit constipation. With the introduction of the concept of STC and the normalization of STC treatment, development of surgical treatment in slow transit constipation is continuous, and the innovation of the operation method in slow transit constipation is continuous as well from partial colectomy, total colectomy (including ileorectal anastomosis, anorectal anastomosis and ileum bag anal canal anastomosis) to subtotal colectomy (including ileosigmoid colon anastomosis, isoperistaltic cecum rectal anastomosis and antiperistaltic cecum rectal anastomosis). Among these procedures, total colectomy ileorectal anastomosis is the ideal surgical procedure for the treatment of STC. Recent studies revealed that subtotal colectomy cecum rectal anastomosis could also achieve good efficacy. In addition, the other procedures for the treatment of STC include ileostomy, anterograde colonic lavage and colon exclusion, but it is necessary to strictly grasp the indications. With the development of minimally invasive technology, the application of laparoscopic technology in STC has been emphasized gradually. In general, the operation method has experienced from simple to complex and individual choice; from single surgical approach to multiple surgical methods; from abdominal open surgery to laparoscopic minimally invasive surgery. Relieving constipation symptoms and reducing the incidence of complications is the goal of surgical treatment that has always been the pursuit of STC surgery. The surgical method with good efficacy, small trauma, quick recovery and less complications must be designed to meet the individualized needs of patients with different constipations. In this paper, the efficacy and progress of surgical treatment of slow transit constipation from the generation and development are reviewed. PMID- 29577226 TI - Neuronal nitric oxide synthase phosphorylation induced by docosahexaenoic acid protects dopaminergic neurons in an experimental model of Parkinson's disease. AB - INTRODUCTION: Docosahexaenoic acid (DHA) has been shown to have beneficial effects on Parkinson's disease (PD). The aim of this study was to investigate if the DHA acts on neurons of substantia nigra (SN) by phosphorylation of neuronal nitric oxide synthase (nNOS) in an experimental mouse model of PD. MATERIAL AND METHODS: An experimental model of PD was created by intraperitoneal injections (4 * 20 mg/kg) of the neurotoxin 1-methyl-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP). Three-month-old male C57BL/6 mice were randomly divided into four groups as follows: control (C), DHA-treated (DHA), MPTP-injected (MPTP) and DHA-treated and MPTP-injected (DHA + MPTP). DHA (36 mg/kg/day) was administered daily by gavage for four weeks. Motor activity of the mice was evaluated with pole, locomotor activity and rotarod tests. Caspase-3 activity, nitrate/nitrite and 4 hydroxynonenal (4-HNE) levels were determined by spectrophotometric assays. Immunohistochemistry was used to localize and assess the expressions of tyrosine hydroxylase (TH), nNOS and phospho-nNOS (p-nNOS) in SN. RESULTS: An increased return and total down time in the MPTP group was observed in the pole test, while DHA treatment decreased both parameters. The ambulatory activity, total distance and total locomotor activities were decreased in the MPTP group, whereas they were increased by DHA treatment. MPTP-treated animals exhibited shorter time on the rod test which was significantly increased by DHA treatment. DHA administration significantly decreased 4-HNE and nitrate/nitrite levels of SN supernatants and protected the TH (+) dopaminergic neurons of SN in the DHA + MPTP group compared to the MPTP group. DHA treatment significantly decreased nNOS and increased p-nNOS immunoreactivities in the DHA + MPTP group compared to the MPTP group. CONCLUSIONS: These results indicate that DHA treatment protects dopaminergic neurons in SN via increasing nNOS serine 852 phosphorylation in the experimental mice model of PD. PMID- 29577228 TI - Large pragmatic randomised controlled trials in peri-operative decision making: are they really the gold standard? PMID- 29577227 TI - Pathological study of pulmonary toxicity induced by intratracheally instilled Asian sand dust (Kosa): effects of lowered serum zinc level on the toxicity. AB - : I: NTRODUCTION: We have previously reported that Asian sand dust (ASD) induced acute and chronic inflammatory changes in the lung of mice. Zinc (Zn) is reported to influence inflammation and wound healing. The purpose of the study was to assess the effects of lowered serum Zn levels on the lung toxicity induced by ASD. MATERIAL AND METHODS: Mice that were fed diets containing normal (group 1) or low (group 2) content of Zn for 8 weeks were intratracheally instilled with 3.0 mg of ASD, followed by sacrifice at 24 hours, 2 weeks, and 1, 2 and 3 months after instillation. Paraffin sections of lung tissues were stained by hematoxylin and eosin and by immunohistochemistry to detect tumor necrosis factor (TNF) and interleukin (IL)-1beta as well as inflammasome (NALP3), autophagy (LC-3) and lysosome (LAMP-1) markers. Selected samples of lung tissue were examined by electron microscopy. RESULTS: Following histological examination of the lung, similar patterns of inflammatory changes were observed in mice with normal and low serum Zn concentrations; however, they were more prominent and persistent in mice with low serum Zn level. These changes were both purulent (acute) and pyogranulomatous (chronic) in nature. In the lung lesions of group 2 mice the changes within the cytoplasmic vacuoles of enlarged ASD-containing macrophages (Mo) were clearly visible. The macrophages expressed TNF and IL-1beta, and semi quantitative analysis revealed a larger number of TNF-positive Mo in mice with normal level of serum Zn and a larger number of IL-1beta-positive Mo in mice with low level of serum Zn. Decreased positive LC-3 staining and dilated lysosomes containing ASD particles were observed in the cytoplasm of Mo in mice with low serum Zn concentration. CONCLUSIONS: These findings suggest that low serum zinc concentration may induce the modulation of cytokine expression and lysosomal malfunction by phagocytotic and/or autophagic mechanisms, and may result in interstitial pyogranulomatous inflammation in the lungs of mice treated with ASD. PMID- 29577229 TI - Comparison of guidelines for the treatment of unipolar depression: a focus on pharmacotherapy and neurostimulation. AB - OBJECTIVE: To determine the level of agreement across a set of evidence-based guidelines for management of the unipolar depressive disorders and with a focus on physical treatments. METHOD: A literature search was undertaken using the terms 'depression', 'depressive' and 'guidelines', using PubMed, Cochrane Database of Systematic Reviews and the National Guideline Clearinghouse. Twelve national psychiatric or professional guideline-producing organizations were identified from the period 2007-2017, with guidelines qualitatively reviewed by two assessors. RESULTS: For major depressive disorder (MDD), there was general consensus to use an antidepressant (AD) in cases of greater severity, although disagreement on AD use in mild to moderate depression. There was some agreement on choice of AD class in first-line treatment recommendations, though great variability in second- and third-line management particularly in recommended augmentation and combined AD strategies. Electroconvulsive therapy was considered in all but one guideline, with other neurostimulation treatments being less consistently covered and with variable recommendations. Finally, there was low consistency in the management of dysthymia, persistent depressive disorder and treatment resistant depression. CONCLUSION: Our review identifies varying levels of consistency in guideline recommendations. Strategies to improve reliability in guideline formulation should also improve their validity. PMID- 29577230 TI - Neutron-based computed microtomography: Pliobates cataloniae and Barberapithecus huerzeleri as a test-case study. AB - OBJECTIVES: High-resolution imaging of fossils with X-ray computed microtomography (MUCT) has become a very powerful tool in paleontological research. However, fossilized bone, embedding matrix, and dental tissues do not always provide a distinct structural signal with X-rays. We demonstrate the benefits of high-resolution neutron radiation in three different specimens showing problematic contrasts with X-ray MUCT. MATERIALS AND METHODS: We compare neutron with X-ray MUCT scans of fossils from two Miocene catarrhines from the Valles-Penedes Basin: the cranium (IPS58443.1, holotype) of the putative stem hominoid Pliobates cataloniae, to discriminate between bone and matrix; and two lower molars (IPS1724n,o, holotype) of Barberapithecus huerzeleri, to discriminate among dental tissues. RESULTS: X-ray MUCT scans of these specimens fail to retrieve any contrast between matrix/bone and enamel/dentine, whereas neutron MUCT scans deliver high-contrast images, enabling a proper evaluation of the specimens' internal anatomy. DISCUSSION: Low bone/matrix intensity difference with X-ray MUCT scans in IPS58443.1 is due to the extreme similarity in chemical composition between the matrix and the fossilized tissues, and the presence of high-density elements. In IPS1724, it is attributable to the convergence of enamel and dentine compositions during fossilization. On the contrary, neutron radiation returns very different contrasts for different isotopes of the same element and easily penetrates most metals. Neutron-based MUCT scans therefore enable a correct definition of the bone/sediment and enamel/dentine interfaces, and hence a better segmentation of the images stack. We conclude that neutron radiation represents a successful alternative for high-resolution uCT of small sized fossils that are problematic with X-rays.

PMID- 29577231 TI - Morphological variation in the genus Chlorocebus: Ecogeographic and anthropogenically mediated variation in body mass, postcranial morphology, and growth. AB - OBJECTIVES: Direct comparative work in morphology and growth on widely dispersed wild primate taxa is rarely accomplished, yet critical to understanding ecogeographic variation, plastic local variation in response to human impacts, and variation in patterns of growth and sexual dimorphism. We investigated population variation in morphology and growth in response to geographic variables (i.e., latitude, altitude), climatic variables (i.e., temperature and rainfall), and human impacts in the vervet monkey (Chlorocebus spp.). METHODS: We trapped over 1,600 wild vervets from across Sub-Saharan Africa and the Caribbean, and compared measurements of body mass, body length, and relative thigh, leg, and foot length in four well-represented geographic samples: Ethiopia, Kenya, South Africa, and St. Kitts & Nevis. RESULTS: We found significant variation in body mass and length consistent with Bergmann's Rule in adult females, and in adult males when excluding the St. Kitts & Nevis population, which was more sexually dimorphic. Contrary to Rensch's Rule, although the South African population had the largest average body size, it was the least dimorphic. There was significant, although very small, variation in all limb segments in support for Allen's Rule. Females in high human impact areas were heavier than those with moderate exposures, while those in low human impact areas were lighter; human impacts had no effect on males. CONCLUSIONS: Vervet monkeys appear to have adapted to local climate as predicted by Bergmann's and, less consistently, Allen's Rule, while also responding in predicted ways to human impacts. To better understand deviations from predicted patterns will require further comparative work in vervets. PMID- 29577233 TI - An assessment of the tolerability of the Cook staged extubation wire in patients with known or suspected difficult airways extubated in intensive care. AB - The Cook staged extubation set (Cook Medical) has been developed to facilitate management of the difficult airway. A guidewire inserted before tracheal extubation provides access to the subglottic airway should re-intubation be required. This prospective cohort study examines patients' tolerance of the guidewire and its impact on clinical status around tracheal extubation in the intensive care unit. Vital signs, incidence of symptoms and patient tolerance of the wire were recorded. Twenty-three patients were enrolled and 17 (73%) tolerated the wire for 4 h. Nasendoscopy was performed in 11 of these patients and revealed one wire was in the oesophagus. The most common symptom was a mild intermittent cough in 13 patients. There was no impact of the guidewire on nursing care in 16 patients, tolerable impact in five and severe impact necessitating removal of the wire in one patient.

PMID- 29577236 TI - Recurrence and chronicity of major depressive disorder and their risk indicators in a population cohort. AB - OBJECTIVE: The naturalistic course of major depressive disorder (MDD) and risk indicators for recurrence and chronicity are best studied using a population sample without clear selection bias. However, such studies are scarce. This limits clinical decision-making concerning monitoring and maintenance treatment. METHOD: Data were used from the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological cohort study among a representative adult population. Two groups at baseline were selected to study recurrence and chronicity of MDD at follow-up. Diagnoses were assessed with the Composite International Diagnostic Interview 3.0. RESULTS: Among remitted MDD cases (n = 746), the cumulative recurrence rate was 4.3% at 5 years, 13.4% at 10 years and 27.1% at 20 years. Time to recurrence was predicted by vulnerability characteristics (childhood abuse, negative life events, parental psychopathology), physical health, functioning, clinical characteristics of depression (previous episodes, severity, medication use), psychiatric comorbidity and mental health use. Among current MDD cases (n = 242), 12% developed a chronic depressive episode over 6 years. Chronic course was predicted by similar risk indicators as recurrence, except for vulnerability characteristics and physical health. CONCLUSION: These risk indicators may help to identify patients requiring monitoring and who could benefit from preventive interventions or maintenance treatment.

PMID- 29577238 TI - Stress ulcer prophylaxis in adult intensive care unit patients - a protocol for a systematic review. AB - BACKGROUND: In the intensive care unit (ICU), stress ulcer prophylaxis with proton pump inhibitors or histamine-2-receptor antagonists is standard of care although gastrointestinal bleeding remains uncommon. It remains unknown whether its use is associated with benefits or harms and the quality of evidence supporting the use of stress ulcer prophylaxis has been questioned. Accordingly, the objective of this systematic review was to critically assess the evidence from randomized clinical trials on the benefits and harms of stress ulcer prophylaxis vs. placebo or no prophylaxis in adult ICU patients. METHODS: We will systematically search for randomized clinical trials in major international databases. Two authors will independently screen and select trials for inclusion, extract data and assess the methodological quality using the Cochrane risk of bias tool. Any disagreement will be resolved by consensus. We will perform conventional meta-analyses using Review Manager, and STATA 15, and we will assess the risk of random errors using Trial Sequential Analysis. Also, we will assess and report the overall quality of evidence for all outcomes according to GRADE. DISCUSSION: The evidence on the benefits and harms of stress ulcer prophylaxis in adult ICU patients is unclear and an updated systematic review is warranted as new trials have been published. To control risks of systematic and random errors, we will use Cochrane and GRADE methodology and Trial Sequential Analysis. Our ambition with this systematic review is to provide updated, reliable and precise data to better inform decision makers on the use of stress ulcer prophylaxis in adult ICU patients.

PMID- 29577244 TI - Treatment of scalp dysesthesia utilising simple exercises and stretches: A pilot study. AB - BACKGROUND/OBJECTIVES: Scalp dysesthesia is characterised by abnormal cutaneous sensations such as burning, stinging or itching of the scalp in the absence of objective dermatological findings. We hypothesised that the unpleasant sensations are the result of a sensory neuropathy secondary to cervical spine dysfunction and chronic tension of the pericranial muscles. The aim of this pilot study was to evaluate the use of an exercise protocol consisting of cervical spine range of movement exercises, gentle mobilisation and muscle stretches over 4 weeks. The exercise protocol was designed to relieve cervical nerve compression through the restoration of cervical homeostasis. METHODS: In total, 16 participants, aged 18 71 (average 45 years), diagnosed with scalp dysesthesia were recruited from an outpatient dermatology clinic and given instructions on how to perform a specifically designed exercise protocol twice daily for 4 weeks. Baseline characteristics and a visual analogue scale (VAS) for pruritus were recorded prior to commencement and a VAS for pruritus recorded weekly thereafter. RESULTS: At week 4, 10 participants experienced a satisfactory reduction in their symptoms, four experienced complete resolution and two experienced no benefit, with no adverse effects reported. We conclude that a programme of simple exercises and stretches is an effective treatment for scalp dysesthesia. CONCLUSIONS: This low-risk treatment is easily implemented, non-invasive and non pharmacological. Within the limits of this small pilot study, benefits are shown, and we believe further research is warranted. PMID- 29577245 TI - Longitudinal Associations Among Child Maltreatment, Resting Frontal Electroencephalogram Asymmetry, and Adolescent Shyness. AB - Child maltreatment is linked to distinct neurophysiological patterns and social emotional vulnerability. Relations among maltreatment, relative resting frontal alpha asymmetry, shyness, and psychopathology were examined prospectively. Adolescent girls (age 14-16) who experienced child maltreatment (N = 55) were compared to nonmaltreated controls (N = 25), and returned for 6- and 12-month follow-ups. Among participants exhibiting relative right frontal asymmetry, maltreated adolescents reported higher shyness than controls at Time 1. Low stable and high-stable shyness trajectories were observed for maltreated participants. Compared to low shy, participants in high-shy trajectory reported at Time 3: higher neuroticism and generalized anxiety; and lower extraversion if they also exhibited relative right frontal asymmetry. Thus, right frontal brain activity and shyness are involved in social-emotional vulnerability of adolescents who experienced child maltreatment. PMID- 29577246 TI - Labels or Concepts? The Development of Semantic Networks in Bilingual Two-Year Olds. AB - The adult lexicon links concepts and labels with related meanings (e.g., dog cat). How do children's encounters with concepts versus labels contribute to semantic development? Three studies investigated semantic priming in 40 monolinguals and 32 bilinguals, who have similar experience with concepts but different experience with labels (i.e., monolinguals hear "dog," bilinguals hear "dog" and "chien"). Similarities in performance across monolinguals and bilinguals at age 24 months, as well as across bilinguals' two languages at age 30 months, support the position that encounters with concepts contribute more to early semantic development than encounters with labels. Findings also suggest that the effects of semantic priming are challenging to observe at 24 months but are strong in bilinguals by age 30 months. PMID- 29577247 TI - Accelerated barrier recovery and enhancement of the barrier integrity and properties by topical application of a pH 4 vs. a pH 5.8 water-in-oil emulsion in aged skin. AB - BACKGROUND: Increased skin-surface pH is an important host-related factor for deteriorated barrier function in aged skin. OBJECTIVES: We investigated whether restoration of skin pH through topical application of a water-in-oil emulsion with pH 4 improved the barrier homeostasis in aged skin, and compared the effects with an identical galenic formulation with pH 5.8. METHODS: The effects of the test formulations on barrier recovery were investigated by repeated measurements of transepidermal water loss (TEWL) and skin pH 3 h, 6 h and 24 h after acetone induced impairment of barrier function in aged skin. The long-term effects of the pH 4 and pH 5.8 emulsions were analysed by investigation of the barrier integrity and cohesion, the skin-surface pH and the skin roughness and scaliness before and after a 4-week, controlled application of the formulations. RESULTS: The application of the pH 4 emulsion accelerated barrier recovery in aged skin: 3 h and 6 h after acetone-induced barrier disruption the differences in the TEWL recovery between the pH 4 treated and acetone control fields were significant. Furthermore, long-term application of the pH 4 formulation resulted in significantly decreased skin pH, enhanced barrier integrity and reduced skin surface roughness and scaliness. At the same time points, the pH 5.8 formulation exerted only minor effects on the barrier function parameters. CONCLUSIONS: Exogenous acidification through topical application of a water-in-oil emulsion with pH 4 leads to improvement of the skin barrier function and maintenance of the barrier homeostasis in aged skin. PMID- 29577248 TI - Behavioural repertoire of free-range laying hens indoors and outdoors, and in relation to distance from the shed. AB - BACKGROUND: Access to an outdoor area is believed to allow free-range hens to express a greater behavioural repertoire. However, very little research has been done in this area. We hypothesised that the type and frequency of behaviours would differ between areas that vary in their characteristics and distance from the shed. METHODS: This preliminary study investigated the behaviour of free range laying hens in indoor and outdoor areas on one commercial free-range farm, through video recordings and scan sampling of focal hens, with the aim of determining their behavioural repertoire and time budget. RESULTS: While ranging, hens spent most of their time foraging. Indoors, hens preened and rested. Behaviour in the wintergarden showed similarities to both the indoor and outdoor areas, with preening, resting and foraging behaviours. Differences were not in the main behavioural repertoire, but rather in terms of time budget, with access to the range and wintergarden encouraging exploration. CONCLUSION: There was no difference in the types of behaviours that hens performed in the outdoor range compared with inside the shed, but access to a wintergarden and the outdoor range were favoured by the hens for foraging. PMID- 29577249 TI - A survey of northern Victorian dairy farmers to investigate dairy calf management: colostrum feeding and management. AB - OBJECTIVES: To describe colostrum management practices carried out in northern Victorian dairy herds and to identify weaknesses in these areas that may affect calf health and welfare by comparing the results with the current industry recommendations METHODS: A questionnaire to obtain information about colostrum management and calf-rearing practices was sent to commercial dairy farming clients of Rochester Veterinary Practice between June and September 2013. The questionnaire consisted of a general herd overview and colostrum harvesting practices. RESULTS: The response rate was 39% (58/150). Many dairy producers were not meeting the current industry recommendations in the following areas: (1) time of removal calf from the dam, (2) relying on calf suckling colostrum from the dam to achieve adequate passive transfer, (3) failing to supplement calves with colostrum, (4) feeding inadequate volumes of colostrum, (5) delayed colostrum harvesting, (6) pooling of colostrum, (7) failing to objectively assess colostrum quality or relying on visual assessment and (8) storing colostrum for a prolonged periods of time at ambient temperatures. CONCLUSION: The results from this survey highlight the need for greater awareness of industry standards for colostrum management and feeding hygiene. PMID- 29577251 TI - Reproductive performance of cows after fixed-time artificial insemination with ovulation synchronisation and re-synchrony in southern Australian dairy herds. AB - OBJECTIVE: To describe reproductive performance of lactating dairy cows after fixed-time artificial insemination (FTAI) with ovulation synchronisation and re synchrony in Australian dairy herds, and to compare reproductive outcomes with those of conventional mating programs. METHODS: The study was conducted in two seasonally calving dairy herds in which lactating dairy cows (n = 675) were enrolled into three treatment groups: group 1, oestrus detection and AI for 34 days followed by a natural service period; group 2, FTAI on day 1 followed by re synchrony of all cows prior to ultrasound pregnancy diagnosis at day 31 and FTAI of cows diagnosed not pregnant at day 34, then a natural service period; group 3, FTAI on day 1 followed by oestrus detection and AI for 34 days, then a natural service period. First-service conception rate (FSCR), 6-week in-calf (6WIC) rate and proportions pregnant at the end of mating were compared using logistic regression with farm fitted as a fixed effect. Times from mating start date to conception were described using survival analysis with Kaplan-Meier failure functions. RESULTS: FSCRs (45.3%, 49.1% and 45.6% for groups 1, 2 and 3, respectively) and proportions pregnant at the end of mating (77.6%, 76.0% and 76.8% for groups 1, 2 and 3, respectively) were similar for all groups. The 6WIC rate in group 2 was similar to that in group 3 (70.4% vs. 67.2%; P = 0.486), but tended to be higher than in group 1 (70.4% vs. 62.0%, P = 0.066). The median days to pregnancy for cows that conceived was 1 day in groups 2 and 3 and 10 days in group 1. CONCLUSION: Mating plans that use FTAI with ovulation synchronisation and re-synchrony during the AI period can achieve comparable reproductive performance to conventional mating programs in seasonally calving dairy herds. PMID- 29577252 TI - A survey of northern Victorian dairy farmers to investigate dairy calf management: calf-rearing practices. AB - OBJECTIVES: To describe the calf-rearing practices carried out in northern Victorian dairy herds and to identify weaknesses that may affect calf health and welfare by comparing the results with current industry recommendations. METHODS: Survey of dairy farms from Rochester and the surrounding farming area. RESULTS: The response rate was 39% (58/150). Many dairy producers were not meeting the current industry recommendations in the following areas: (1) delayed access to pellets and roughage, (2) failing to provide access to water from birth, (3) delayed disbudding of calves, (4) delayed timing of booster vaccinations, (5) weaning based on age alone, (6) failing to isolate sick calves and (7) early sale age of excess calves. CONCLUSION: The results from this survey highlight the need for greater awareness of industry standards for calf husbandry and weaning. PMID- 29577253 TI - Antimicrobial susceptibility testing by Australian veterinary diagnostic laboratories. AB - BACKGROUND: The national strategy for tackling antimicrobial resistance highlights the need for antimicrobial stewardship in veterinary practice and for surveillance of antimicrobial susceptibility in veterinary pathogens. Diagnostic laboratories have an important role in facilitating both of these processes, but it is unclear whether data from veterinary diagnostic laboratories are similar enough to allow for compilation and if there is consistent promotion of appropriate antimicrobial use embedded in the approaches of different laboratories to susceptibility testing. METHODS: A cross-sectional study of antimicrobial susceptibility testing and reporting procedures by Australian veterinary diagnostic laboratories was conducted in 2017 using an online questionnaire. All 18 veterinary diagnostic laboratories in Australia completed the questionnaire. RESULTS: Kirby-Bauer disc diffusion was the method predominantly used for antimicrobial susceptibility testing and was used to evaluate 86% of all isolates, although two different protocols were used across the 18 laboratories (CLSI 15/18, CDS 3/18). Minimum inhibitory concentrations were never reported by 61% of laboratories. Common isolates were consistently reported on across all species, except for gram-negative isolates in pigs, for which there was some variation in the approach to reporting. There was considerable diversity in the panels of antimicrobials used for susceptibility testing on common isolates and no consistency was apparent between laboratories for any bacterial species. CONCLUSION: We recommend that nationally agreed and consistent antimicrobial panels for routine susceptibility testing should be developed and a uniform set of guidelines should be adopted by veterinary diagnostic laboratories in Australia. PMID- 29577256 TI - Corrigendum. PMID- 29577254 TI - Prevalence and risk factors for medical events following exercise at Australian Greyhound race meetings. AB - AIM: A prospective, observational study to determine the prevalence of post exercise conditions at Australian Greyhound race meetings and to assess association with race performance and other environmental, race- and dog-related factors was undertaken. METHODS: A total of 4020 starters were observed (2813 Greyhounds, 1009 trainers, 536 races, 52 race meets, 48 race dates and 11 race tracks) following a race. The presence of diaphragmatic flutter (DF), ataxia, seizure, collapse or sudden death was recorded. Risk factors were screened by univariable logistic regression prior to multivariable backward stepwise model building. RESULTS: In this study, 962 starters (n = 768 dogs) had DF (23.9%), 16 starters were ataxic (0.4%) and there were no observed cases of collapse, seizure or sudden death. Race track location, increasing race distance, race grade based on increasing 1st place prize value, lower (earlier) race number at the meeting, age, a previous observation of DF at the last start, females, colour (white) and better finishing position were all associated with an increased risk of a Greyhound being observed with DF. However, when logistic regression assessing the random effect of dog was performed, the presence of previous DF was not significant. In this cohort, DF was common following strenuous exercise in Greyhounds and on its own does not appear to result in reduced performance or distress to the animal. CONCLUSION: The incidence of ataxia was low and collapse, seizure and sudden death were not observed. However, even though uncommon, ataxia has welfare concerns for racing Greyhounds that warrants further investigation. PMID- 29577257 TI - Pharmacogenetics of vitamin K antagonists and bleeding risk prediction in atrial fibrillation. AB - BACKGROUND: Polymorphisms in the vitamin K epoxide reductase complex 1 (VKORC1) and cytochrome P450 2C9 (CYP2C9) genes increase the bleeding risk in anticoagulated atrial fibrillation (AF) patients. Here, we aimed to investigate whether VKORC1 and CYP2C9 polymorphisms improved the predictive performance for major bleeding using the HAS-BLED score. MATERIAL AND METHODS: We recruited 652 consecutive AF patients stable on vitamin K antagonist (INR 2.0-3.0) during at least the previous 6 months. A baseline venous blood sample was obtained for DNA extraction. We gave an extra point to the HAS-BLED score if the patient was a simultaneous carrier of the VKORC1 and CYP2C9 polymorphisms related to bleeding, and we called this modified score "GEN|HAS-BLED." During a median follow-up of 7.6 years (IQR 5.6-8.0), all major bleeding events were recorded. RESULTS: During follow-up, 106 (16.2%) patients experienced a major bleeding (2.81%/y; 42 intracranial haemorrhages and 44 gastrointestinal bleeding) and 24 (3.7%) died from major bleeding (0.48%/y). Cox regression analyses demonstrated a significant association between HAS-BLED or GEN|HAS-BLED and major bleeds, both as continuous or categorical scores. Comparison of receiver operating characteristic (ROC) curves shows that original HAS-BLED clinical score had better predictive ability than GEN|HAS-BLED (0.660, 95% CI 0.622-0.696 vs 0.645, 95% CI 0.607-0.682; P = .030). Discrimination and reclassification analyses showed that GEN|HAS-BLED did not improve sensitivity compared with the original score and even showed significant negative reclassification. CONCLUSION: Adding pharmacogenetic factors (ie polymorphisms of the VKORC1 and CYP2C9 genes) to the HAS-BLED score does not improve the prediction or discrimination performance for major bleeding. PMID- 29577259 TI - Elevated high-sensitive troponin T in negative stress test individuals. AB - BACKGROUND: The exercise ECG stress test (EST) is still the first step of work-up in intermediate risk patients in many clinical scenarios. High-sensitive cardiac troponin T (hs-cTnT) elevation is related to future cardiovascular events in the general population and in patients with ischaemic heart disease. The relation between these 2 tests is not well described. MATERIALS AND METHODS: A total of 2780 participants from the Tel-Aviv Medical Center Inflammation Survey cohort (mean age 49 years, 79% men) were analysed. Multiple physiologic and metabolic parameters including hs-cTnT were collected. All participants completed an EST manually reviewed by a cardiologist. RESULTS: A positive EST was documented in 224 subjects (8%). The majority (91%) of participants with hs-cTnT levels of 5-14 ng/L had a negative EST as well as 89.3% of subjects with levels >14 ng/L. The proportion of subjects with a positive EST and detectable hs-cTnT levels (>5 ng/L) was not significantly greater compared to those with a negative EST (53.1% vs 46.2%, respectively, P = .09). CONCLUSION: Among subjects referred for EST as part of an annual health survey, we found no significant association between EST results to hs-cTnT detection. PMID- 29577258 TI - Gamma-aminobutyric acid levels in cerebrospinal fluid in neuropaediatric disorders. AB - AIM: Gamma-aminobutyric acid (GABA) is a major modulator in brain maturation and its role in many different neurodevelopmental disorders has been widely reported. Although the involvement of GABA in different disorders has been related to its regulatory function as an inhibitory neurotransmitter in the mature brain, co transmitter, and signalling molecule, little is known about its role as a clinical biomarker in neuropaediatric disorders. The aim of this study is to report the cerebrospinal fluid (CSF) free-GABA concentrations in a large cohort of patients (n=85) with different neurological disorders. METHOD: GABA was measured in the CSF of neuropaediatric patients using capillary electrophoresis with laser-induced fluorescence detection. Other neurotransmitters (amino acids and monoamines) were also analysed. RESULTS: GABA concentrations in CSF were abnormal, with a greater frequency (44%) than monoamines (20%) in neuropaediatric patients compared with our reference values. Although we included a few patients with inborn errors of metabolism, GABA levels in CSF were more frequently abnormal in metabolic disorders than in other nosological groups. INTERPRETATION: Our work suggests further research into brain GABAergic status in neuropaediatric disorders, which could also lead to new therapeutic strategies. WHAT THIS PAPER ADDS: Homeostasis of GABA seems more vulnerable than that of monoamines in the developing brain. The highest GABA levels are found in the primary GABA neurotransmitter disorder SSADH deficiency. GABA alterations are not specific for any clinical or neuroimaging presentation. PMID- 29577260 TI - Usefulness of The C-Reactive Protein/Albumin Ratio for Predicting No-Reflow in ST elevation myocardial infarction treated with primary percutaneous coronary intervention. AB - BACKGROUND: The ratio of serum C-reactive protein (CRP) to albumin has been proven to be a more accurate indicator than albumin and CRP levels alone in determining the prognosis of patients with cancer and critical illness. The aim of this study was to determine whether the CRP/albumin ratio (CAR) can be linked to imperfect reperfusion that can worsen the prognosis of ST-elevation myocardial infarction (STEMI) in patients treated with primary percutaneous coronary intervention (pPCI). MATERIALS AND METHODS: A total of 1217 consecutive STEMI patients who achieved epicardial vessel patency with pPCI were recruited to this study. RESULTS: The study population was divided into 2 groups: reflow (n = 874) and no-reflow (NR) (n = 343) groups. The white blood cell count (WBC), neutrophil to-lymphocyte ratio (NLR) and CAR (0.03 [0.01-0.04] vs 0.06 [0.03-0.12] (P < .001) were significantly higher in the NR group than in the reflow group, and these factors were found to be independent predictors of NR development. The best cut-off value of CAR predicting NR was 0.59 with a sensitivity of 54.7% and specificity of 86.7. The predictive power of CAR surpassed that of CRP, albumin, WBC count and NLR in the receiver operator curve (ROC) curve comparison. CONCLUSION: No-reflow can be predicted by systemic inflammation markers including WBC count, NLR and CAR measured from the blood sample obtained on admission. CAR has a higher clinical value than CRP, albumin level, WBC count and NLR in NR prediction. PMID- 29577262 TI - Galli-Galli disease responsive to isotretinoin treatment. PMID- 29577261 TI - Clock genes alterations and endocrine disorders. AB - BACKGROUND: Various endocrine signals oscillate over the 24-hour period and so does the responsiveness of target tissues. These daily oscillations do not occur solely in response to external stimuli but are also under the control of an intrinsic circadian clock. DESIGN: We searched the PubMed database to identify studies describing the associations of clock genes with endocrine diseases. RESULTS: Various human single nucleotide polymorphisms of brain and muscle ARNT like 1 (BMAL1) and Circadian Locomotor Output Cycles Kaput (CLOCK) genes exhibited significant associations with type 2 diabetes mellitus. ARNTL2 gene expression and upregulation of BMAL1 and PER1 were associated with the development of type 1 diabetes mellitus. Thyroid hormones modulated PER2 expression in a tissue-specific way, whereas BMAL1 regulated the expression of type 2 iodothyronine deiodinase in specific tissues. Adrenal gland and adrenal adenoma expressed PER1, PER2, CRY2, CLOCK and BMAL1 genes. Adrenal sensitivity to adrenocorticotrophin was also affected by circadian oscillations. A significant correlation between the expression of propio-melanocorticotrophin and PER 2, as well as between prolactin and CLOCK, was found in corticotroph and lactosomatotroph cells, respectively, in the pituitary. Clock genes and especially BMAL1 showed an important role in fertility, whereas oestradiol and androgens exhibited tissue-specific effects on clock gene expression. Metabolic disorders were also associated with circadian dysregulation according to studies in shift workers. CONCLUSIONS: Clock genes are associated with various endocrine disorders through complex mechanisms. However, data on humans are scarce. Moreover, clock genes exhibit a tissue-specific expression representing an additional level of regulation. Their specific role in endocrine disorders and their potential implications remain to be further clarified.

AB - The objective of this study was to use the Biobehavioral Family Model (BBFM) to delineate which psychophysiological variables link romantic and family relationship satisfaction variables to health outcomes. Data from individuals who reported being partnered from the second wave of the National Survey of Midlife Development in the United States (MIDUS II), Project 4 (n = 812) were used to test a structural equation model which explored which psychophysiological variables potentially mediated associations between positive and negative family emotional climate variables and disease activity. This model found that current and past family variables had larger associations with the psychophysiological variables than romantic partner variables; depressive symptoms, anxiety, and inflammation partially mediated associations between family relationships and health; and, contrary to the hypotheses, romantic partner and family support were linked to worse health outcomes. However, the findings should be viewed with regard to the cross-sectional design of the study. Overall, the findings support the use of the BBFM as a model that can guide clinical interventions. PMID- 29577265 TI - Specificity of the Association between Marital Discord and Longitudinal Changes in Symptoms of Depression and Generalized Anxiety Disorder in the Irish Longitudinal Study on Ageing. AB - This longitudinal study was conducted to evaluate actor and partner effects of marital discord on changes in symptoms of depression and generalized anxiety disorder (GAD) in a large population sample of Irish adults (N = 1,445 couples), adjusting for the potential confounds of quality of other social relationships and other psychopathology symptoms. The Actor-Partner Interdependence Model was used to examine actor and partner effects of marital discord on changes in symptoms of depression and GAD at a 2-year follow-up. Additional models examined these associations adjusting for family and friend discord and symptoms of the other type of psychopathology (depressive or GAD symptoms). Actor effects of marital discord on depressive and anxiety symptoms were greater for men than for women. There were significant, positive actor effects of marital discord on depressive symptoms for husbands and wives, which remained significant when adjusting for family and friend discord and GAD symptoms. There were significant, positive actor effects of marital discord on GAD symptoms for husbands, which remained significant when adjusting for family and friend discord and depressive symptoms. Results demonstrate that longitudinal associations between marital discord and depressive symptoms (for wives and husbands) and GAD symptoms (for husbands) are incremental to other rival explanations (family and friend discord and the other set of symptoms). Findings provide evidence for a potential causal association leading from marital discord to symptoms of depression and GAD. PMID- 29577266 TI - Knowledge, attitudes and practices regarding methicillin-resistant Staphylococcus aureus (MRSA) infection control and nasal MRSA carriage rate among dental health care professionals. AB - BACKGROUND: Dental health-care professionals (DHCPs) with nasal colonisation of methicillin-resistant Staphylococcus aureus (MRSA) can serve as a reservoir for MRSA transmission to others and be exposed to self-contamination with MRSA. Evaluating the knowledge, attitudes and actual practice of DHCPs is imperative for appropriate infection control. METHODS: Dentists, dental hygienists and dental technologists from Seoul National University Dental Hospital were recruited to participate in a cross-sectional survey and undergo nasal sampling of MRSA. The survey included demographic questions, six questions about knowledge, eight questions about attitudes/perceptions and six questions about practices/behaviours regarding MRSA infection control. Nasal samples from the participants were analysed for MRSA presence, antimicrobial susceptibility and staphylococcal cassette chromosome mec (SCCmec) typing. MRSA carriers underwent decolonisation with topical mupirocin. RESULTS: Among 139 DHCPs, four (2.9%) were nasal MRSA carriers. Decolonisation was successful in three participants. One participant was decolonised with topical fusidic acid after failure to decolonise with mupirocin. Dentists had a higher knowledge score compared with the other professionals (P < 0.05). Dental hygienists scored higher on practice questions compared with the other professionals (P < 0.05). There was a significant, positive correlation between attitude and practice scores (P < 0.01). CONCLUSIONS: The nasal MRSA carriage rate among DHCPs is 2.9%, which is higher than that in the general population but lower than that in other health-care professionals. Further education of DHCPs on MRSA, especially regarding its seriousness, is needed to improve MRSA infection control in a dental hospital setting. PMID- 29577267 TI - Parental Perceptions of Individual and Dyadic Adjustment as Predictors of Observed Coparenting Cohesion: A Cross-National Study. AB - : Over the past 20 years, systemically guided approaches to understanding early family processes have helped to provide greater clarity concerning the interplay among individual, dyadic, and family level processes. Parental depression, marital functioning, and child adjustment in particular appear to be reliable predictors of coparental and family level functioning. Indeed, cohesion at the level of the family group covaries in theoretically meaningful ways with these indicators of individual and dyadic adjustment. In this study, two collaborating research groups (one in Switzerland, the second in the United States) partnered to examine whether similar patterns of relationships exist among individual and marital adjustment and coparenting processes in families of 4-year-old children. Using similar constructs but disparate and occasionally dissimilar measures, both groups measured parent-reported depression, marital satisfaction, and child behavior problems. Coparenting cooperation and warmth were observed during family interactions. Despite differences between samples and evaluation tools, similar results were found for the Swiss and U.S. SAMPLES: A model with depression, marital satisfaction, and child symptoms as predictors of a latent factor of observed coparenting cooperation and warmth showed good fit to data in both samples, suggesting the model was relevant for each. Parameter estimation showed that higher coparenting cooperation and warmth was predicted by lower maternal depression and higher child internalizing symptoms. The common significant effects despite differences in assessment paradigms and instrumentation are of substantive interest. Future directions pertinent to the coparenting questions addressed in this research are discussed. PMID- 29577268 TI - Associations of Army Fathers' PTSD Symptoms and Child Functioning: Within- and Between-Family Effects. AB - This study examined the within-family and between-family associations between fathers' military-related PTSD symptoms and parent ratings of children's behavioral and emotional problems. The sample included married couples (N = 419) with children composed of a civilian wife and an active-duty husband serving in the U.S. Army. Results indicate that changes in fathers' PTSD symptoms over time were associated with corresponding changes in both mothers' and fathers' reports of child behavioral and emotional problems. These within-family findings were independent from between-family effects, which showed that higher average PTSD symptomatology was associated with more overall behavioral and emotional problems for children. This study uses advances in statistical methodologies to increase knowledge about how PTSD symptoms and child problems are related, both across different families and over time within families. PMID- 29577269 TI - PME-1 is regulated by USP36 in ERK and Akt signaling pathways. AB - Deubiquitinating enzymes (DUBs) play an important role in the ubiquitin proteasome system (UPS) by eliminating ubiquitins from substrates and inhibiting proteasomal degradation. Protein phosphatase methylesterase 1 (PME-1) inactivates protein phosphatase 2A (PP2A) and enhances the ERK and Akt signaling pathways, which increase cell proliferation and malignant cell transformation. In this study, we demonstrate that USP36 regulates PME-1 through its deubiquitinating enzyme activity. USP36 increases PME-1 stability, and depletion of USP36 decreases the PME-1 expression level. Furthermore, we demonstrate that USP36 promotes the ERK and Akt signaling pathways. In summary, it is suggested that USP36 regulates PME-1 as a DUB and participates in the ERK and Akt signaling pathways. PMID- 29577270 TI - Cardiovascular Reactivity During Marital Conflict in Laboratory and Naturalistic Settings: Differential Associations with Relationship and Individual Functioning Across Contexts. AB - Cardiovascular reactivity during spousal conflict is considered to be one of the main pathways for relationship distress to impact physical, mental, and relationship health. However, the magnitude of association between cardiovascular reactivity during laboratory marital conflict and relationship functioning is small and inconsistent given the scope of its importance in theoretical models of intimate relationships. This study tests the possibility that cardiovascular data collected in laboratory settings downwardly bias the magnitude of these associations when compared to measures obtained in naturalistic settings. Ambulatory cardiovascular reactivity data were collected from 20 couples during two relationship conflicts in a research laboratory, two planned relationship conflicts at couples' homes, and two spontaneous relationship conflicts during couples' daily lives. Associations between self-report measures of relationship functioning, individual functioning, and cardiovascular reactivity across settings are tested using multilevel models. Cardiovascular reactivity was significantly larger during planned and spontaneous relationship conflicts in naturalistic settings than during planned relationship conflicts in the laboratory. Similarly, associations with relationship and individual functioning variables were statistically significantly larger for cardiovascular data collected in naturalistic settings than the same data collected in the laboratory. Our findings suggest that cardiovascular reactivity during spousal conflict in naturalistic settings is statistically significantly different from that elicited in laboratory settings both in magnitude and in the pattern of associations with a wide range of inter- and intrapersonal variables. These differences in findings across laboratory and naturalistic physiological responses highlight the value of testing physiological phenomena across interaction contexts in romantic relationships.

PMID- 29577272 TI - Effect of a tissue selective estrogen complex on breast cancer: Role of unique properties of conjugated equine estrogen. AB - The Women's Health Initiative studies reported that the menopausal hormone therapy (MHT) regimen containing conjugated equine estrogen (CEE) and medroxyprogesterone acetate increased, whereas CEE alone reduced breast cancer incidence. These observations suggest the possibility that CEE might exert unique actions on breast and also suggest the need to eliminate the progestogen from MHT regimens. A MHT regimen called a tissue selective estrogen complex (TSEC), containing CEE plus bazedoxifene (BZA), to avoid the need for a progestogen, was developed and FDA approved. Our study addressed two questions regarding this TSEC: (i) whether CEE exert effects on breast cancer which differ from those of estradiol (E2 ) and (ii) whether BZA antagonize the effects of E2 and CEE on breast cancer? Two rodent models (NMU and ACI) were used to compare the effect of CEE with E2 on mammary tumor formation, proliferation and apoptosis. In both the NMU and ACI models, E2 significantly increased tumor incidence and multiplicity whereas in striking contrast CEE did not, even though the estrogenic effects of CEE and E2 on uterine weight were identical. Mechanistically E2 blocked whereas CEE stimulated apoptosis (cleaved caspase-3) in ACI animals and only E2 stimulated proliferation (Ki67). BZA exerted highly potent anti-estrogenic effects on tumors by completely blocking palpable tumor formation. These data suggest that the CEE/BZA TSEC may be a safer, breast-antagonistic, MHT agent for women and might have potential to prevent breast cancer while relieving menopausal symptoms. PMID- 29577273 TI - Impact of introducing specific measures to reduce the frequency of cesarean delivery for non-obstetric indications. AB - OBJECTIVE: To identify the frequency of cesarean delivery for non-obstetric indications before and after the introduction of specific measures to lower the rate of elective cesarean, and to evaluate the effectiveness of the introduced measures. METHODS: In the present single-center retrospective cohort study at University Hospital Trnava, Trnava, Slovak Republic, the frequency of elective cesarean was evaluated before (January 1, 2010, to December 31, 2014) and after (January 1, 2015, to December 31, 2016) the implementation of specific measures applied in January 2015 to confirm the indications for primary cesarean delivery. The frequency of elective cesarean delivery for non-obstetric indications was compared between the two periods. RESULTS: Before the intervention in 2015, 229 (2.9%) of 7768 women had elective cesarean deliveries for non-obstetric indications. After implementation of the intervention, the frequency decreased to 27 (0.8%) of 3203 women (P<0.001). CONCLUSION: The frequency of cesarean delivery for non-obstetric indications was reduced significantly by introducing specific reasonable measures. These included all non-obstetric indications for cesarean delivery being approved by a leading specialist of the related department, close cooperation with professionals from other specialties, and, additionally, staff attending professional educational lectures. PMID- 29577274 TI - Disentangling the effects of multiple environmental drivers on population changes within communities. AB - The effects of different environmental drivers on the changes in species' population abundances can be difficult to disentangle as they often act simultaneously. Researchers have built statistical models that include environmental variables (such as annual temperature) or species attributes (such as a species' temperature preference), which are assumed to detect the impacts of specific drivers (such as climate change). However, these approaches are often applied separately or, if combined, not explicitly compared. We show the complementary insights gained by applying both these approaches to a community dataset on Danish terrestrial birds. We use our analysis to compare the relative importance of climate change and agricultural land-use change for the abundance changes within the community between 1983 and 2013. Population models were fitted to the community data of species' annual abundances with predictors comprising: species attributes (species' temperature and habitat preferences), environmental variables (climatic and agricultural land-use change variables) or both. Relationships between species' abundances and environmental variables were used to identify the drivers associated with average abundance changes of species in the community. Relationships between species' abundances and their attributes were used to understand the drivers causing interspecific variation in abundance changes. Warmer winters were positively associated with community-level abundances, and warm-adapted species had more positive abundance changes than cold-adapted ones. Agricultural land-use area was negatively associated with community-level abundances, and birds using a high proportion of meadow and habitat specialists had more negative abundance changes than birds using other habitats and habitat generalists. Effect sizes of environmental variables were larger for agricultural land-use change while those of species attributes were larger for climate change. The environmental data approach suggested that agricultural land-use change has decreased the average abundances of species in the community, affecting total community size while the species attribute-based approach suggested that climate change has caused variation in abundance among species, affecting community composition. Environmental variables and species attributes that are hypothesized to link to specific drivers can be used together to provide complementary information on the impacts of different drivers on communities. PMID- 29577275 TI - Central place foragers and moving stimuli: A hidden-state model to discriminate the processes affecting movement. AB - Human activities can influence the movement of organisms, either repelling or attracting individuals depending on whether they interfere with natural behavioural patterns or enhance access to food. To discern the processes affecting such interactions, an appropriate analytical approach must reflect the motivations driving behavioural decisions at multiple scales. In this study, we developed a modelling framework for the analysis of foraging trips by central place foragers. By recognising the distinction between movement phases at a larger scale and movement steps at a finer scale, our model can identify periods when animals are actively following moving attractors in their landscape. We applied the framework to GPS tracking data of northern fulmars Fulmarus glacialis, paired with contemporaneous fishing boat locations, to quantify the putative scavenging activity of these seabirds on discarded fish and offal. We estimated the rate and scale of interaction between individual birds and fishing boats and the interplay with other aspects of a foraging trip. The model classified periods when birds were heading out to sea, returning towards the colony or following the closest boat. The probability of switching towards a boat declined with distance and varied depending on the phase of the trip. The maximum distance at which a bird switched towards the closest boat was estimated around 35 km, suggesting the use of olfactory information to locate food. Individuals spent a quarter of a foraging trip, on average, following fishing boats, with marked heterogeneity among trips and individuals. Our approach can be used to characterise interactions between central place foragers and different anthropogenic or natural stimuli. The model identifies the processes influencing central place foraging at multiple scales, which can improve our understanding of the mechanisms underlying movement behaviour and characterise individual variation in interactions with a range of human activities that may attract or repel these species. Therefore, it can be adapted to explore the movement of other species that are subject to multiple dynamic drivers. PMID- 29577276 TI - Soluble gammac receptor attenuates anti-tumor responses of CD8+ T cells in T cell immunotherapy. AB - Previous studies have shown that soluble common gamma-chain (sgammac) modulates CD4+ T cell immunity with antagonistic functions in gammac cytokine signaling. However, the role of sgammac in functional properties of effector CD8+ T cells has not been fully defined. In this study, we report a new mechanism by which the anti-tumor activity of mouse CD8+ T cells is suppressed in sgammac of their own producing. While sgammac significantly inhibits cytotoxicity of CD8+ T cells, blocking sgammac production by genetic modification leads to potentiated effector function of CD8+ T cells, establishing persistent CD8+ T cells. This is due to the modulation of IL-2 and IL-15 signaling, which is required for expansion and survival of CD8+ T cells as well as for optimal cytotoxic activity. More efficient management of tumor growth was achieved by an adoptive transfer of sgammac-deficient CD8+ T cells than that of wild-type or sgammac-overexpressing CD8+ T cells. Blocking of IL-2 and IL-15 signaling by sgammac attenuates the capacity of CD8+ T cells to mount an optimal response to the tumor, with both quantitative and qualitative effects on antigen-specific CD8+ T cells. These results could have a critical implication for the generation and survival of optimal effector T cells for adoptive immunotherapy of cancer. PMID- 29577277 TI - Alternative splice variants of DCLK1 mark cancer stem cells, promote self-renewal and drug-resistance, and can be targeted to inhibit tumorigenesis in kidney cancer. AB - Renal cell carcinoma (RCC) is a common and devastating disease characterized by a hypoxic microenvironment, epithelial-mesenchymal transition and potent resistance to therapy evidencing the presence of cancer stem cells (CSCs). Various CSC markers have been studied in RCC, but overall there is limited data on their role and most markers studied have been relatively nonspecific. Doublecortin-like kinase 1 (DCLK1) is a validated CSC marker in the gastrointestinal tract and evidence for an equivalent role in other cancers is accumulating. We used bioinformatics, immunohistochemistry, flow cytometry, spheroid self-renewal and chemoresistance assays in combination with overexpression and siRNA-knockdown to study the stem cell-supportive role of DCLK1 alternative splice variants (DCLK1 ASVs) in RCC. To target tumor cells expressing DCLK1 ASVs directly, we developed a novel monoclonal antibody (CBT-15) and delivered it systemically to RCC tumor xenografts. DCLK1 ASVs were overexpressed, enriched together with CSC markers and predictive of overall and recurrence-free survival in RCC patients. In vitro, DCLK1 ASVs were able to directly stimulate essential molecular and functional characteristics of renal CSCs including expression of aldehyde dehydrogenase, self-renewal and resistance to FDA-approved receptor tyrosine kinase and mTOR inhibitors, while targeted downregulation of DCLK1 reversed these characteristics. Finally, targeting DCLK1 ASV-positive cells with the novel CBT 15 monoclonal antibody blocked RCC tumorigenesis in vivo. These findings establish DCLK1 as a CSC marker with implications for therapy, disease progression and survival in RCC and demonstrate the therapeutic value of DCLK1 targeted monoclonal antibodies against renal CSCs. PMID- 29577278 TI - Evaluation of Enterococcus faecium NRRL B-2354 as a Surrogate for Salmonella During Extrusion of Low-Moisture Food. AB - : Salmonella in low-moisture foods is an emerging challenge due to numerous food product recalls and foodborne illness outbreaks. Identification of suitable surrogate is critical for process validation at industry level due to implementation of new Food Safety Modernization Act of 2011. The objective of this study was to evaluate Enterococcus faecium NRRL B-2354 as a surrogate for Salmonella during the extrusion of low-moisture food. Oat flour, a low-moisture food, was adjusted to different moisture (14% to 26% wet basis) and fat (5% to 15% w/w) contents and was inoculated with E. faecium NRRL B-2354. Inoculated material was then extruded in a lab-scale single-screw extruder running at different screw speeds (75 to 225 rpm) and different temperatures (75, 85, and 95 degrees C). A split-plot central composite 2nd order response surface design was used, with the central point replicated six times. The data from the selective media (m-Enterococcus agar) was used to build the response surface model for inactivation of E. faecium NRRL B-2354. Results indicated that E. faecium NRRL B 2354 always had higher heat resistance compared to Salmonella at all conditions evaluated in this study. However, the patterns of contour plots showing the effect of various product and process parameters on inactivation of E. faecium NRRL B-2354 was different from that of Salmonella. Although E. faecium NRRL B 2354 may be an acceptable surrogate for extrusion of low-moisture products due to higher resistance than Salmonella, another surrogate with similar inactivation behavior may be preferred and needs to be identified. PRACTICAL APPLICATION: Food Safety Modernization Act requires the food industry to validate processing interventions. This study validated extrusion processing and demonstrated that E. faecium NRRL B-2354 is an acceptable surrogate for extrusion of low-moisture products. The developed response surface model allows the industry to identify process conditions to achieve a desired lethality for their products based on composition. PMID- 29577279 TI - Partitioning of the primate intraparietal cortex based on connectivity pattern and immunohistochemistry for Cat-301 and SMI-32. AB - We propose a partitioning of the primate intraparietal sulcus (IPS) using immunoarchitectural and connectivity criteria. We studied the immunoarchitecture of the IPS areas in the capuchin monkey using Cat-301 and SMI-32 immunohistochemistry. In addition, we investigated the IPS projections to areas V4, TEO, PO, and MT using retrograde tracer injections in nine hemispheres of seven animals. The pattern and distribution of Cat-301 and SMI-32 immunostaining revealed multiple areas in the IPS, in the adjoining PO cleft and in the annectant gyrus, with differential staining patterns found for areas V3d, DM, V3A, DI, PO, POd, CIP-1, CIP-2, VIPa, VIPp, LIPva, LIPvp, LIPda, LIPdp, PIPv, PIPd, MIPv, MIPd, AIPda, AIPdp, and AIPv. Areas V4, TEO, PO, MT, which belong to different cortical streams of visual information processing, receive projections from at least twenty different areas within the IPS and adjoining regions. In six animals, we analyzed the distribution of retrogradely labeled cells in tangential sections of flat-mount IPS preparations. The lateral bank of the IPS projects to regions belonging both to the ventral (V4 and TEO) and dorsal (PO and MT) streams. The region on the floor of the IPS (i.e., VIP) projects predominantly to dorsal stream areas. Finally, the medial bank of the IPS (i.e., MIP) projects solely to the dorsalmedial stream (PO). Therefore, our data suggest that ventral and dorsal streams remain segregated within the IPS, and that its projections to the dorsal stream can be further segregated based on those targeting the dorsolateral versus the dorsomedial subdivisions. PMID- 29577281 TI - Effects of therapist-worn protective equipment during functional analysis of aggression. AB - The effects of therapist-worn protective equipment (PE) on functional analysis (FA) outcomes for aggression were evaluated. Independent FAs with and without PE were conducted concurrently. Both FAs showed the same function of aggression for all participants. These results suggest that therapists may wear PE during FAs of aggression to reduce risk without altering the interpretation of the analysis. PMID- 29577280 TI - Emerging depression in adolescence coincides with accelerated frontal cortical thinning. AB - BACKGROUND: Adolescence is a transition period characterized by heightened emotional reactivity, which for some sets the stage for emerging depressive symptoms. Prior studies suggest that adolescent depression is associated with deviant cortical and subcortical brain structure. Longitudinal studies are, however, currently scarce, but critical to detect which adolescents are at risk for developing depressive symptoms. METHODS: In this longitudinal study, a community sample of 205 participants underwent magnetic resonance imaging (MRI) in three biennial waves (522 scans) spanning 5 years across ages 8-25 years. Depressive symptomatology was assessed using self-report at the third time point. Mixed models were used to examine the relations between structural brain development, specifically regional change in cortical thickness, surface area and subcortical volumes (hippocampus and amygdala), and depressive symptoms. RESULTS: Accelerated frontal lobe cortical thinning was observed in adolescents who developed depressive symptoms at the third time point. This effect remained after controlling for parent-reported affective problems at the first time point. Moreover, the effect was driven by specific lateral orbitofrontal and precentral regions. In addition, differential developmental trajectories of parietal cortical thickness and surface area in several regions were found for participants reporting higher depressive symptomatology, but these results did not survive correction for multiple comparisons. Volumes or developmental volume changes in hippocampus or amygdala were not related to depressive symptoms. CONCLUSIONS: This study showed that emerging depression is associated with cortical thinning in frontal regions within individuals. These findings move beyond detecting cross-sectional correlations and set the stage for early detection, which may inform future intervention. PMID- 29577282 TI - Tag retention and mortality of adult Atlantic salmon Salmo salar gastrically tagged with different sized telemetry transmitters. AB - A batch of 1 sea winter pre-spawning adult Salmo salar from the Bush river in Northern Ireland, U.K., were gastrically tagged with large (13 mm diameter) and small (9 mm diameter) dummy acoustic telemetry tags alongside untagged control fish. Survival differed between control and tagged fish and the estimated probability of survival by the end of the study for control fish with no tag was 0.94, small tags was 0.90 and large tags was 0.72. Tag loss through regurgitation was slightly higher for fish tagged with larger tags than for fish tagged with smaller tags and the estimated probability of tag loss for fish with a small tag was 0.10 and for large tags was 0.14. PMID- 29577283 TI - Morphological characterization of HVC projection neurons in the zebra finch (Taeniopygia guttata). AB - Singing behavior in the adult male zebra finch is dependent upon the activity of a cortical region known as HVC (proper name). The vast majority of HVC projection neurons send primary axons to either the downstream premotor nucleus RA (robust nucleus of the arcopallium, or primary motor cortex) or Area X (basal ganglia), which play important roles in song production or song learning, respectively. In addition to these long-range outputs, HVC neurons also send local axon collaterals throughout that nucleus. Despite their implications for a range of circuit models, these local processes have never been completely reconstructed. Here, we use in vivo single-neuron Neurobiotin fills to examine 40 projection neurons across 31 birds with somatic positions distributed across HVC. We show that HVC(RA) and HVC(X) neurons have categorically distinct dendritic fields. Additionally, these cell classes send axon collaterals that are either restricted to a small portion of HVC ("local neurons") or broadly distributed throughout the entire nucleus ("broadcast neurons"). Overall, these processes within HVC offer a structural basis for significant local processing underlying behaviorally relevant population activity. PMID- 29577284 TI - Regulation of eye and jaw colouration in three-spined stickleback Gasterosteus aculeatus. AB - Fish can change their skin and eye colour for background matching and signalling. Males of Gasterosteus aculeatus develop ornamental blue eyes and a red jaw during the reproductive season, colours that are further enhanced during courtship. Here, the effects of different hormones on physiological colour changes in the eyes and jaws of male and female G. aculeatus were investigated in vitro. In an in vivo experiment, G. aculeatus were injected with a receptor blocker of a pivotal hormone (noradrenaline) that controls colour change. In males, noradrenaline had aggregating effects on melanophore and erythrophore pigments resulting in blue eyes and a pale jaw, whereas melanocyte-concentrating hormone (MCH) and melatonin resulted in a pale jaw only. When noradrenalin was combined with melanocyte stimulating hormone (MSH) or prolactin, the jaw became red, while the eyes remained blue. In vivo injection of yohimbine, an alpha-2 adrenoreceptor blocker, resulted in dispersion of melanophore pigment in the eyes and inhibited the blue colouration. Altogether, the data suggest that noradrenalin has a pivotal role in the short-term enhancement of the ornamental colouration of male G. aculeatus, potentially together with MSH or prolactin. This study also found a sex difference in the response to MCH, prolactin and melatonin, which may result from different appearance strategies in males, versus the more cryptic females. PMID- 29577285 TI - Application of Lactobacillus plantarum in Functional Products Based on Fermented Buckwheat. AB - In this work, 12 plant-based potential probiotic mashes were produced by fermenting buckwheat with lactic acid cocci of the Fresco DVS 1010 culture and the human-derived isolate Lactobacillus plantarum HM1. The effect of single and coculture fermentation was studied at 30 and 37 +/- 0.5 degrees C for 8 hr (5% CO2 ), followed by a storage period of 21 days (6 +/- 0.5 degrees C). Although milk is the typical growth medium for lactic acid bacteria (LAB), presumably viable counts of Fresco reached levels of 108 to 109 CFU/mL (specific growth rates ranging from 1.07 to 1.40 hr-1 ) with higher counts in coculture fermentation (13%) that differed statistically significantly (P < 0.05). After storage, 194 to 4700 mg/kg lactic acid was found in the mashes, with significantly higher contents after cocultivation (11% to 96%). Based on the overall acceptance of the designed products, milk-based mashes right after the fermentation were evaluated as the most satisfactory (3.3 to 3.6). Those after the storage period (21 days) exhibited an attractive sensory acceptability (2.2 to 3.2). PMID- 29577286 TI - Antimicrobial Carvacrol in Solution Blow-Spun Fish-Skin Gelatin Nanofibers. AB - : Carvacrol is a volatile monoterpenic phenol and main component of oregano essential oil that shows nonspecific antimicrobial activity against foodborne pathogenic bacteria. Fish-skin gelatin (FSG) nanofibers encapsulating carvacrol (15%, 20%, 25%, and 30%, w/w FSG) were successfully prepared via solution blow spinning (SBS) technique using lecithin (2.475% wb) as the surfactant. FSG emulsions with lower carvacrol ratios (5% and 10%) showed higher values in particle size and surface tension as well as lower values in viscosity and modulus, which led to failure of maintaining nanofibers shape. The formed carvacrol-FSG nanofibers showed round and smooth morphologies with average fiber diameters ranging from 103.2 to 138.1 nm as the carvacrol ratio increased from 15% to 30%. Carvacrol was evenly dispersed within the interior of nanofiber matrix. All carvacrol-FSG nanofibers showed inhibitive effects against the growth of Escherichia coli, Salmonella enterica, and Listeria monocytogenes. Moreover, nanofibers with lower carvacrol ratios showed bigger inhibition zones for E. coli and L. monocytogenes (20 mm compared with 12.5 mm for lowest to highest carvacrol ratios, respectively). Nanofibers stored at 20 degrees C (51% RH) showed better retention (40% to 60%) for carvacrol during the first 4 weeks of storage, while nanofibers stored at 2 degrees C (70% RH) showed better retention (10% to 30%) at the end of storage. PRACTICAL APPLICATION: Results obtained in the study may help with antimicrobial carvacrol addition levels for gelatin fiber preparation using solution blow spinning (SBS) method. SBS gelatin fibers with added antimicrobials have potential applications for food packaging and medical wound dressing. PMID- 29577287 TI - Evaluation of Models for Temperature-Dependent Viscosity Changes in Dairy Protein Beverage Formulations During Thermal Processing. AB - : Rheological modeling as a function of temperature is a useful tool for describing products undergoing thermal processing. The rheological behavior of a range of dairy-based (4%, w/w) protein beverages was investigated for applicability to semi-empirical temperature-dependent viscosity equations. The viscosity at 16.8 rad/s of the beverages was measured during heating, holding, and cooling over a temperature range of 25 to 90 o C using a rheometer with starch pasting cell geometry. Five established fitting methods were applied based on the Arrhenius and Williams-Landel-Ferry (WLF) equations using nonlinear regression analysis. A two-parameter WLF (WLF2 ) model, using viscosity at a reference temperature of 25 o C resulted in high R2 values (0.974 to 0.988) and a statistically superior fit compared to the Arrhenius, Generalized Arrhenius, and exponential equations (P < 0.001). Deviation from the WLF2 modeled equation was used to describe and investigate the effect formulation had on the changes in viscosity during thermal heating. This study successfully applied the WLF equation to a liquid protein system, proving that a consistent and close fit can be achieved across a range of formulations. A rapid, quantitative method for viscosity-temperature profile evaluation is presented, which can ease product development and optimization of product processing stability. PRACTICAL APPLICATION: This study validated the use of the Williams-Landel-Ferry equation to describe the behavior of dairy beverages during thermal processing, providing a better fit to rheological data than the widely used Arrhenius-based equations. In conjunction with the WLF equation, a method was presented which reduced the complex rheological data to a single value, which can aid in the comparison of formulations for product development and optimization in both research and industry. PMID- 29577288 TI - Development of Anti-Insect Microencapsulated Polypropylene Films Using a Large Scale Film Coating System. AB - : Films containing microencapsulated cinnamon oil (CO) were developed using a large-scale production system to protect against the Indian meal moth (Plodia interpunctella). CO at concentrations of 0%, 0.8%, or 1.7% (w/w ink mixture) was microencapsulated with polyvinyl alcohol. The microencapsulated CO emulsion was mixed with ink (47% or 59%, w/w) and thinner (20% or 25%, w/w) and coated on polypropylene (PP) films. The PP film was then laminated with a low-density polyethylene (LDPE) film on the coated side. The film with microencapsulated CO at 1.7% repelled P. interpunctella most effectively. Microencapsulation did not negatively affect insect repelling activity. The release rate of cinnamaldehyde, an active repellent, was lower when CO was microencapsulated than that in the absence of microencapsulation. Thermogravimetric analysis exhibited that microencapsulation prevented the volatilization of CO. The tensile strength, percentage elongation at break, elastic modulus, and water vapor permeability of the films indicated that microencapsulation did not affect the tensile and moisture barrier properties (P > 0.05). The results of this study suggest that effective films for the prevention of Indian meal moth invasion can be produced by the microencapsulation of CO using a large-scale film production system. PRACTICAL APPLICATION: Low-density polyethylene-laminated polypropylene films printed with ink incorporating microencapsulated cinnamon oil using a large-scale film production system effectively repelled Indian meal moth larvae. Without altering the tensile and moisture barrier properties of the film, microencapsulation resulted in the release of an active repellent for extended periods with a high thermal stability of cinnamon oil, enabling commercial film production at high temperatures. This anti-insect film system may have applications to other food-packaging films that use the same ink-printing platform.

AB - : Roasted peanuts are a popular snack in Europe, but their drivers of liking and perceived freshness have not been previously studied with European consumers. Consumer research to date has been focused on U.S. consumers, and only on specific peanut cultivars. In this study, 26 unique samples were produced from peanuts of different types, cultivars, origins, and with different process technologies (including baking, frying, and maceration). The peanut samples were subjected to sensory (expert panel, SpectrumTM ) and instrumental analysis (color, headspace volatiles, sugar profile, large deformation compression tests, and graded by size) and were hedonically rated by consumers in The Netherlands, Spain, and Turkey (n > 200 each). Preference Mapping (PREFMAP) on mean liking models revealed that the drivers of liking are similar across the three countries. Sweet taste, roasted peanut, dark roast, and sweet aromas and the color b* value were related to increased liking, and raw bean aroma and bitter taste with decreased liking. Further partial least square regression (PLSR) modeling of liking and perceived freshness against instrumental attributes showed that the color coordinates in combination with sucrose content and a select few headspace volatiles were strong predictors of both preference and perceived freshness. Finally, additional PLSR models focusing on the headspace volatiles only showed that liking and ''fresh'' attributes were correlated with the presence of several pyrroles in the volatile fraction, and inversely related to ''stale'' and to hexanal and 2-heptanone. PRACTICAL APPLICATION: This study provides insight into which flavor, taste, and appearance attributes drive liking and disliking of roasted peanuts for European consumers. The drivers are linked back to analytical attributes that can be measured instrumentally, thereby reducing the reliance on costly sensory panels. Particular emphasis is placed on color as a predictor of preference, because of the low cost of the measuring equipment, it is available to even smaller producers. In addition to preference, the study also examines whether product attributes that drive perceived freshness exist. The results can be used to design products with high acceptability across several countries within Europe. PMID- 29577290 TI - Aluminum and Heavy Metal Accumulation in Tea Leaves: An Interplay of Environmental and Plant Factors and an Assessment of Exposure Risks to Consumers. AB - : Environmental and plant factors (soil condition, variety, season, and maturity) and exposure risks of aluminum (Al), manganese (Mn), lead (Pb), cadmium (Cd), and copper (Cu) in tea leaves were investigated. The concentrations of these metals in tea leaves could not be predicted by their total concentrations in the soil. During any one season, there were differences in Al, Mn, and Cd levels between tea varieties. Seasonally, autumn tea and/or summer tea had far higher levels of Al, Mn, Pb, and Cd than did spring tea. Tea leaf maturity positively correlated with the concentrations of Al, Mn, Pb, and Cd, but negatively with Cu. The calculated average daily intake doses (mg/ [kg*d]) for these metal elements were 0.14 (Al), 0.11 (Mn), 2.70 * 10-3 (Cu), 2.80 * 10-4 (Pb), and 2.88 * 10-6 (Cd). The hazard quotient values of each metal were all significantly lower than risk level (=1), suggesting that, for the general population, consumption of tea does not result in the intake of excessive amounts of Al, Mn, Pb, Cd, or Cu. This study identified the factors that can be monitored in the field to decrease consumer exposure to Al and Mn through tea consumption. PRACTICAL APPLICATION: Environmental and plant factors influence aluminum and heavy metal accumulation in tea leaves. Consumers of tea are not ingesting excessive Al, Mn, Pb, Cd, or Cu. Trackable factors were identified to manage exposure levels. PMID- 29577291 TI - Validation of a QuEChERS-Based Gas Chromatography-Mass Spectrometry (GC-MS) Method for Analysis of Phthalate Esters in Grain Sorghum. AB - : A modified QuEChERS method coupled with gas chromatography-mass spectrometry (GC-MS) was developed for analysis of 14 phthalate esters (PAEs) in grain sorghum (GS). Chemical extraction was done with acetonitrile followed by dispersive-solid phase extraction technique with a mixture of sorbents including primary secondary amine and octadecyl silica. Under the optimized condition, the matrix-matched calibration curves for all PAEs showed good linear relationship in the concentration range between 5 and 500 MUg/L with correlation coefficients (R2 ) better than 0.99. Mean recoveries were between 82.0% and 120.2% at spiking levels of 0.06, 0.6, and 2.0 mg/kg with RSD of 0.3% to 7.8% (n = 5) for intra-day precision and 1.2% to 7.6% (n = 5) for inter-day precision. The LODGS and LOQGS for 14 PAEs were between 0.4 and 10.0 MUg/kg and 0.5 and 20.0 MUg/kg, respectively. Analysis of 32 commercial GS samples revealed that dimethyl-, diethyl-, diisobutyl-, dibutyl-, and di- (2-ethylhexyl) phthalate esters were detected in all of the analytes. In addition, content-color scale model was applied to visualize the concentration differences of PAEs in real GS samples. Principal component analysis of PAEs revealed that the GS samples did not have a distinctive cluster based on their geographic origins. The established method was proven to be simple, accurate, and effective for analysis of PAEs in GS, which might also be applied for analysis of PAEs in other matrices. PRACTICAL APPLICATION: A modified QuEChERS-based GC-MS method was developed for the determination of phthalate esters (PAEs) in grain sorghum (GS). The ubiquitous presence of PAEs can migrate into GS. Therefore, evaluation of the total content of PAEs in GS is helpful to understand its impact of overall pollution level on other foods. This study has provided some basic information in terms of the content and contamination of PAEs in GS, which is helpful to establish relevant standards and risk assessment of GS for the government. PMID- 29577292 TI - Consequences of electroshock-induced narcosis in fish muscle: from mitochondria to swim performance. AB - Adult zebrafish Danio rerio were exposed to an electric shock of 3 V and 1A for 5 s delivered by field backpack electrofishing gear, to induce a taxis followed by a narcosis. The effect of such electric shock was investigated on both the individual performances (swimming capacities and costs of transport) and at cellular and mitochondrial levels (oxygen consumption and oxidative balance). The observed survival rate was very high (96.8%) independent of swimming speed (up to 10 body length s-1 ). The results showed no effect of the treatment on the metabolism and cost of transport of the fish. Nor did the electroshock trigger any changes on muscular oxidative balance and bioenergetics even if red muscle fibres were more oxidative than white muscle. Phosphorylating respiration rates rose between (mean 1 s.e.) 11.16 +/- 1.36 pmol O2 s-1 mg-1 and 15.63 +/- 1.60 pmol O2 s-1 mg-1 for red muscle fibres whereas phosphorylating respiration rates only reached 8.73 +/- 1.27 pmol O2 s-1 mg-1 in white muscle. Such an absence of detectable physiological consequences after electro-induced narcosis both at organismal and cellular scales indicate that this capture method has no apparent negative post-shock performance under the conditions of this study. PMID- 29577293 TI - Evaluation of Enzymatically Modified Soy Protein Isolate Film Forming Solution and Film at Different Manufacturing Conditions. AB - : The effects of transglutaminase on soy protein isolate (SPI) film forming solution and films were investigated by rheological behavior and physicochemical properties based on different manufacturing conditions (enzyme treatments, enzyme incubation times, and protein denaturation temperatures). Enzymatic crosslinking reaction and changes in molecular weight distribution were confirmed by viscosity measurement and SDS-PAGE, respectively, compared to 2 controls: the nonenzyme treated and the deactivated enzyme treated. Films treated with both the enzyme and the deactivated enzyme showed significant increase in tensile strength (TS), percent elongation (%E), and initial contact angle of films compared to the nonenzyme control film due to the bulk stabilizers in the commercial enzyme. Water absorption property, protein solubility, Fourier transform infrared (FTIR) and X-ray diffraction (XRD) spectroscopy revealed that enzyme treated SPI film matrix in the molecular structure level, resulted in the changes in physicochemical properties. Based on our observation, the enzymatic treatment at appropriate conditions is a practical and feasible way to control the physical properties of protein based biopolymeric film for many different scientific and industrial areas. PRACTICAL APPLICATION: Enzymes can make bridges selectively among different amino acids in the structure of protein matrix. Therefore, protein network is changed after enzyme treatment. The behavior of biopolymeric materials is dependent on the network structure to be suitable in different applications such as bioplastics applied in food and pharmaceutical products. In the current research, transglutaminase, as an enzyme, applied in soy protein matrix in different types of forms, activated and deactivated, and different preparation conditions to investigate its effects on different properties of the new bioplastic film. PMID- 29577294 TI - Caffeine Extraction from Raw and Roasted Coffee Beans. AB - : Coffee is a stimulant, psychoactive, popular daily beverage, and its caffeine affects human physiological health and behavior. These important issues prompted us to study caffeine extraction from both the raw and roasted coffee beans of 3 types at different temperatures. A hemispheric model is developed to simulate the extraction process of the caffeine from the coffee beans of hemisphere is proposed. The experimental data are in good agreement with the predicted model. The effective diffusivities of caffeine in both the raw and roasted beans increase with temperature in all 3 types. An incubation period, decreasing with increasing temperature, is observed in all samples studied. Caffeine extraction in roasted beans is more rapid than that for the raw beans and the time difference is significant at low temperatures. In both the raw and roasted samples, caffeine diffusion in the raw beans and the incubation behavior are thermally activated processes. Single activation energies are obtained for diffusion within the extraction temperature range for all beans tested with the exception of one type of the coffee beans, Mandheling, which exhibits 2 activation energies in raw samples. The surface energies of the epidermis of the raw beans and roasted beans obtained from the contact angle measurements are used to interpret the difference of incubation periods. PRACTICAL APPLICATION: This study has a potential application to the decaffeinated coffee industry.Caffeine affects human physiological health and behavior so that caffeine extraction from coffee beans of different types at different temperatures is important for product refining and customers. PMID- 29577295 TI - UHPLC/MS Identifying Potent alpha-glucosidase Inhibitors of Grape Pomace via Enzyme Immobilized Method. AB - : alpha-Glucosidases have been a major target in controlling and managing postprandial blood glucose and therefore diabetes treatment. This study aims to further identify and purify active compounds from the most active ethyl acetate fraction collected previously in Tinta Cao grape pomace extract (TCEE) using a newly developed and highly effective immobilization method, including obtaining compounds previously shown to inhibit the enzyme. Purification used crosslinked chitosan beads with alpha-glucosidases bound to polymer, which acted as immobilized enzyme vehicle to collect inhibitors. Compounds absorbed into the beads were eluded using methanol, where collected fraction was subjected to UHPLC MS analysis to identify active compounds. Results presented 5 major compounds: viniferifuran (amurensin H), p-coumaroyl-6-O-D-glucopyranoside, p-coumaroyl-6-O hexoside, (epi)catechin-hexoside, 10-carboxyl-pyranopeonidin 3-O-(6''-O-p coumaroyl)-glucoside. These findings indicated the particular molecules can be utilized as potent alpha-glucosidases inhibitors, and may be further tested for postprandial glucose control. PRACTICAL APPLICATION: A potential approach enriched and identified alpha-glucosidase inhibitors of grape pomace. Set-up of UHPLC/MS detection and identification of active compounds provide qualify assessment in developing grape pomace extract into potent dietary supplement and new drug for diabetes. PMID- 29577296 TI - Oral prebiotics and the influence of environmental conditions in vitro. AB - BACKGROUND: Only recently the concept of prebiotics has been introduced in oral health. Few potential oral prebiotics have already been identified in dual species competition assays, showing a stimulatory effect on beneficial bacteria and by this suppressing the outgrowth of pathogenic species. This study aimed to validate the effect of previously identified potential prebiotic substrates on multispecies cultures by shifting the biofilm composition towards a more beneficial species dominated microbiota. METHODS: A chemostat culture containing 14 model oral bacterial species was used to grow biofilms for 24 hours which subsequently were treated with prebiotic solutions three times a day for 3 consecutive days. Further the influence of environmental factors such as pH, nutrient availability, oxygen concentration and prebiotic dose on the efficacy of the prebiotic substances was investigated. RESULTS: Three potential prebiotic substrates N-acetyl-D-mannosamine, succinic acid and Met-Pro were able to bring the beneficial proportion to > 95%. While the pH of the prebiotic solution did not have an influence on the prebiotic effect, the interplay of nutrient availability, oxygen concentration and prebiotic treatment resulted in significant changes of the microbial composition identifying N-acetyl-D mannosamine as the most promising oral prebiotic substrate. Showing a clear dose dependent effect, concentrations of N-acetyl-D-mannosamine of 1.0 and 1.5 M resulted in a biofilm composition of 97% beneficial species. CONCLUSION: Introducing the prebiotic concept in oral health might reveal a valid approach for treatment and prevention of oral diseases and promote oral health.

PMID- 29577298 TI - Individual self > relational self > collective self-But why? Processes driving the self-hierarchy in self- and person perception. AB - OBJECTIVE: The self has three parts: individual, relational, and collective. Typically, people personally value their individual self most, their relational self less, and their collective self least. This self-hierarchy is consequential, but underlying processes have remained unknown. Here, we propose two process accounts. The content account draws upon selves' agentic-communal content, explaining why the individual self is preferred most. The teleology account draws upon selves' instrumentality for becoming one's personal ideal, explaining why the collective self is preferred least. METHOD: In Study 1 (N = 200, 45% female, Mage = 32.9 years, 79% Caucasian), participants listed characteristics of their three selves (individual, relational, collective) and evaluated those characteristics in seven preference tasks. Additionally, we analyzed the characteristics' agentic-communal content, and participants rated their characteristics' teleological instrumentality. Study 2 (N = 396, 55% female, Mage = 34.5 years, 76% Caucasian) used identical methodology and featured an additional condition, where participants evaluated the selves of a friend. RESULTS: Study 1 reconfirmed the self-hierarchy and supported both process accounts. Study 2 replicated and extended findings. As hypothesized, when people evaluate others' selves, a different self-hierarchy emerges (relational > individual > collective). CONCLUSIONS: This research pioneers process-driven explanations for the self-hierarchy, establishing why people prefer different self-parts in themselves than in others. PMID- 29577299 TI - Amplification and adaptation of centromeric repeats in polyploid switchgrass species. AB - Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats from a single satellite repeat family. Why centromeres are dominated by a single satellite repeat and how the satellite repeats originate and evolve are among the most intriguing and long-standing questions in centromere biology. We identified eight satellite repeats in the centromeres of tetraploid switchgrass (Panicum virgatum). Seven repeats showed characteristics associated with classical centromeric repeats with monomeric lengths ranging from 166 to 187 bp. Interestingly, these repeats share an 80-bp DNA motif. We demonstrate that this 80-bp motif may dictate translational and rotational phasing of the centromeric repeats with the cenH3 nucleosomes. The sequence of the last centromeric repeat, Pv156, is identical to the 5S ribosomal RNA genes. We demonstrate that a 5S ribosomal RNA gene array was recruited to be the functional centromere for one of the switchgrass chromosomes. Our findings reveal that certain types of satellite repeats, which are associated with unique sequence features and are composed of monomers in mono-nucleosomal length, are favorable for centromeres. Centromeric repeats may undergo dynamic amplification and adaptation before the centromeres in the same species become dominated by the best adapted satellite repeat. PMID- 29577300 TI - Prevalence of Virulence Genes in Extended-Spectrum beta-lactamases (ESBLs) Producing Salmonella in Retail Raw Chicken in China. AB - Extended-spectrum beta-lactamases (ESBLs)-producing Salmonella is a tremendous hazard to food safety and public health. The objective of this study was to determine the prevalence of 30 virulence genes (avrA, sipA, sseC, marT, rhuM, siiE, pipA, pipD, envR, gogB, gtgA, sodC1, sseI, irsA, sopE2, spvC, rck, spvR, fhuA, msgA, pagK, srfj, stkc, fimA, lpfD, pefA, stcC, steB, stjB, and tcfA) in 156 ESBLs-producing Salmonella isolates that belonged to 21 serotypes. These isolates were recovered from retail raw chicken samples collected from 5 provinces and 2 national cities in China between 2007 and 2012. The results indicated that 154 (98.7%) ESBLs-producing Salmonella isolates carried at least 1 virulence gene, 138 (88.5%) simultaneously carried at least 5 virulence genes, 107 (68.6%) carried 10 or more, and 20 (12.8%) carried 15 or more virulence genes. The most frequently detected virulence genes were marT (n = 127, 81.4%), siiE (n = 126, 80.8%), msgA (n = 121, 77.6%), and sipA (n = 121, 77.6%). Significant difference was identified between detection percentages of virulence genes of rhuM, pipD, envR, sopE2, pagK, lpfD, steB, and stjB in S. Indiana, S. Thompson, S. Enteritidis, S. Typhimurium, S. Shubra, S. Edinburg, and S. Agona isolates. Distribution of virulence genes were significantly influenced by sampling districts (P < 0.01), especially for sodC1 and pipD, and then were msgA and sopE2. The heatmap showed the frequencies of virulence genes in ESBLs producing isolates from retail chickens in southern, central, and northern regions of China were completely different from each other. Based on our findings, ESBLs-producing Salmonella of retail chicken origin were common carriers of multiple virulence genes and were regionally distributed. PMID- 29577301 TI - Effect of Different Heat Treatments on In Vitro Digestion of Egg White Proteins and Identification of Bioactive Peptides in Digested Products. AB - : Chicken eggs are ingested by people after a series of processes, but to date, only a few studies have explored the nutrient variations caused by different heat treatments. In this work, the impacts of different heat treatments (4, 56, 65, and 100 degrees C on the in vitro digestibility of egg white proteins were investigated by hydrolysis with pepsin or pepsin + pancreatin to simulate human gastrointestinal digestion, and the digested products were identified using Nano LC-ESI-MS/MS. Egg white proteins treated at 65 degrees C had the highest in vitro pepsin digestibility value whereas the pepsin + pancreatin digestibility increased significantly (P < 0.05) as the cooking temperature was raised. The molecular weight distribution of the digested products indicated that, when compared to pepsin-treated samples, pepsin + pancreatin-treated samples contained more low-molecular-weight peptides (m/z < 849.2) with higher signal intensities. The number of unique peptides identified in every digestion product showed a positive correlation with their in vitro digestibility. Additionally, bioactive peptides such as antioxidant, antimicrobial and antihypertensive peptides were found present in egg white digested products, especially in samples treated at 4 and 100 degrees C. PRACTICAL APPLICATION: These findings may facilitate a better understanding of nutritive values of egg white proteins and their digested products under different cooking temperatures, such as antibacterial and antioxidant peptides identified in the digestion samples treated, respectively at 4 and 100 degrees C. This study also provided information for improving the applications of eggs in the food industry as well as a theoretical basis for egg consumption. PMID- 29577302 TI - Flow cytometry for assessing the efficacy of interspecific gynogenesis induction in sturgeon. AB - The efficacy of ploidy analysis for separating progeny of Siberian sturgeon Acipenser baerii after induced gynogenesis was demonstrated using sperm of a paternal species differing in ploidy level from the maternal species. Gynogenesis was induced in tetraploid A. baerii with UV-C irradiated sperm from the diploid sterlet Acipenser ruthenus and vice-versa. The success of sperm UV irradiation and diploidy restoration by heat-shock was estimated based on the ploidy level of progeny, confirmed by microsatellite parentage assignment. Hatching rates of interspecific gynogenotes were comparable with rates reported for gynogenesis induction using sperm and eggs of the same species. Juvenile mortality was similar to that observed in the control hybrids. The efficiency and reliability of this method may foster its use for production of gynogenotes in aquaculture, potentially allowing interspecific gynogenesis to replace intraspecific. PMID- 29577303 TI - CT findings in Pneumocystis carinii pneumonia in five dogs. AB - Pneumocystis carinii pneumonia is a rare disease in dogs. It is primarily reported in cavalier King Charles spaniels and miniature dachshunds with suspected underlying immunodeficiency. This case series reports the findings in five dogs (four cavalier King Charles spaniels and one Bedlington terrier) with confirmed P. carinii pneumonia. Thoracic (CT) revealed ground glass opacity of the pulmonary parenchyma with a diffuse or multifocal distribution. The severity of this pattern was variable. Less consistent imaging findings included parenchymal bands, bronchial dilation and signs consistent with pulmonary hypertension. Four dogs recovered well with treatment and there was resolution of CT abnormalities in all dogs with follow-up.

PMID- 29577306 TI - Clinical safety of percutaneous ultrasound-guided fine-needle aspiration of adrenal gland lesions in 19 dogs. AB - OBJECTIVE: To evaluate the safety of fine-needle aspiration of adrenal gland lesions in dogs and to characterise the risks in a subset of patients with cytologically or histopathologically diagnosed phaeochromocytoma. MATERIALS AND METHODS: Retrospective review of medical records of dogs that underwent percutaneous ultrasound-guided fine-needle aspiration of adrenal gland lesions between August 2014 and December 2016. Nineteen dogs were identified, with three undergoing bilateral adrenal gland aspiration and one dog undergoing aspiration twice, yielding 23 cytology samples in total. Data collected included signalment, concurrent medical conditions, current medications, blood pressure and heart rate before adrenal fine-needle aspiration, imaging characteristics of the adrenal gland lesions and any clinically apparent procedure-related complications. RESULTS: Phaeochromocytoma was diagnosed in nine of 19 dogs, including one dog with bilateral phaeochromocytoma. One dog developed ventricular tachycardia following aspiration of an adrenal gland lesion cytologically consistent with a phaeochromocytoma. CLINICAL SIGNIFICANCE: Percutaneous ultrasound-guided fine needle aspiration of adrenal gland lesions appears to be relatively safe, even in phaeochromocytoma, but further data are required to lend more weight to this finding. Minimally invasive aspirates could be considered as part of the diagnostic algorithm in the investigation of an incidentally detected adrenal gland lesion of uncertain clinical significance. PMID- 29577305 TI - Aberrant cortical excitability reflects the loss of hand dexterity in musician's dystonia. AB - KEY POINTS: Dystonia is a movement disorder characterized by abnormalities at multifaceted aspects of motor dexterity and neural functions. Evidence bridging between pathophysiology and movement abnormalities is limited. A novel finding was that in focal task-specific dystonia (FTSD), an aberrantly reduced inhibition at the motor cortex was related to the temporal imprecision of the dexterous finger movements, whereas an elevated facilitation was associated with an abnormally sluggish transition of finger movements from flexion to extension. We newly identified two sets of behavioural-physiological covariations as hallmarks of hand FTSD, which is clinically significant because these findings provide novel evidence connecting distinct types of malfunctions within the motor cortex at rest with distinct aspects of motor dexterity degradation in FTSD patients. ABSTRACT: Focal task-specific dystonia (FTSD) compromises dexterous movements. A proposed pathophysiological mechanism of FTSD involves malfunction of the motor cortex (M1). However, no evidence is yet available regarding whether and how malfunctions of M1 are responsible for the loss of motor dexterity. Here, we addressed this issue by assessing both M1 excitability and detailed movement parameters, as well as their relationships. Transcranial magnetic stimulation was applied over M1 in 20 pianists with FTSD, 20 healthy pianists and 20 non musicians. The patients demonstrated both reduced short-interval intracortical inhibition (SICI) and elevated intracortical facilitation (ICF) compared with the healthy controls. This indicates that the abnormal cortical excitability reflects pathophysiology but not current skills. Hand motor dexterity was evaluated by position sensors during piano playing at two tempi. The patients showed delayed transition from finger flexion to extension at the fastest tempo and greater timing variability of the finger movements. Furthermore, multivariate analyses identified distinct sets of covariation between cortical excitability and dexterity measures. Namely, the SICI measure and ICF measure were associated with the temporal variability of the movements and the quickness of the transition from flexion to extension, respectively. Specifically, the reduced inhibition and elevated facilitation at M1 in pianists was related to the temporal imprecision and impairment of quick transitions in the sequential finger movements. The present study provides novel evidence associating M1 malfunctions with dexterity loss. PMID- 29577307 TI - Importance of weather monitoring for agricultural decision-making - an exploratory behavioral study for Oklahoma Mesonet. AB - BACKGROUND: The Oklahoma Mesonet (the statewide environmental and weather monitoring network) has monitored changes in weather patterns since 1994 to provide accurate and timely mesoscale weather information to farmers and other groups. Studies are still scarce that would quantitatively assess farmers' perceptions about the value of the Oklahoma Mesonet contributions to agricultural operations, profitability of land management, and decision making. This paper aims to analyze those questions by means of an exploratory empirical study in Oklahoma for two groups of Mesonet users and non-users. RESULTS: Familiarity with and application of Mesonet information determines farmers' profitability assessments and decision making. Farmers' perceptions are also influenced by the degree of previous exposure to weather-related losses. The median estimate of the economic value of Mesonet information is $1000 per year. Mesonet users perceive higher profitability from the application of Mesonet data at 7.6/10, whereas Mesonet non-users provided an average assessment of 2.6/10. CONCLUSIONS: Consistent use of Mesonet information results in a higher assessment of the importance of Mesonet. This research provides some initial insights into farmers' perceptions about the value of Oklahoma Mesonet information, which could guide stakeholders in developing measures to better serve farmers with environmental monitoring data for improved farm decisions.

AB - The seventh and last chapter of Vygotsky's Thinking and Speech (1934) is generally considered as his final word in psychology. It is a long chapter with a complex argumentative structure in which Vygotsky gives his view on the relationship between thinking and speech. Vygotsky's biographers have stated that the chapter was dictated in the final months of Vygotsky's life when his health was rapidly deteriorating. Although the chapter is famous, its structure has never been analyzed in any detail. In the present article we reveal its rhetorical structure and show how Vygotsky drew on many hitherto unrevealed sources to convince the reader of his viewpoint. PMID- 29577309 TI - Determination of changes in the concentration and distribution of elements within olive drupes (cv. Leccino) from Se biofortified plants, using laser ablation inductively coupled plasma mass spectrometry. AB - BACKGROUND: Biofortification of food crops has been used to increase the intake of Se in the human diet, even though this may change the concentration of other elements and modify the nutritional properties of the enriched food. Selenium biofortification programs should include routine assessment of the overall mineral composition of enriched plants. RESULTS: Laser ablation inductively coupled plasma mass spectrometry (LA ICP-MS) was used for the assessment of mineral composition of table olives. Olive trees were fertilized with sodium selenate before flowering. At harvest, the edible parts of drupes proved to be significantly enriched in Se, delivering 6.1 MUg g-1 (39% of the RDA for five olives). Such enrichment was followed by significant changes in the concentrations of B, Mg, K, Cr, Mn, Fe and Cu in edible parts, which are discussed for their impact on food quality. CONCLUSION: The biofortification of olive plants has allowed the enrichment of fruits with selenium. Enrichment with selenium has caused an increase in the concentration of other elements, which can change the nutritional quality of the drupes. The analytical technique used well as a valuable tool for routinely determining the chemical composition of all fruit parts. (c) 2018 Society of Chemical Industry. PMID- 29577310 TI - Quantitative analysis of amino acids in human and bovine colostrum milk samples through iTRAQ labeling. AB - BACKGROUND: The types and quantity of proteins vary widely between bovine and human milk, with corresponding differences in free and hydrolytic amino acids. In this study, the free and hydrolytic amino acids of bovine and human colostrum were for the first time qualitatively and quantitatively determined using isobaric tags for relative and absolute quantification technology combined with liquid chromatography tandem mass spectrometry detection. RESULTS: Total free amino acid content was 0.32 g L-1 and 0.63 g L-1 in bovine and human colostrum respectively, with free amino acid content in human colostrum twice that of bovine colostrum. However, total hydrolytic amino acid content was 4.2 g L-1 and 2.2 g L-1 in bovine and human colostrum respectively. We found that the hydrolytic amino acid content in bovine colostrum was higher than that in human colostrum; however, the amount of free amino acids and the overall amino acid content in human colostrum were respectively substantially higher and more varied than in bovine colostrum. CONCLUSION: Our findings revealed differences between bovine and human colostrum, with these data providing the basis for further research into amino acid metabolomics and infant formula.

PMID- 29577311 TI - Analysis of the cocobiota and metabolites of Moniliophthora perniciosa-resistant Theobroma cacao beans during spontaneous fermentation in southern Brazil. AB - BACKGROUND: Cocoa bean fermentation is a spontaneous process involving a succession of microbial activities, yeasts, lactic acid, and acetic acid bacteria. The spontaneous fermentation of cocoa beans by Theobroma cacao TSH565 clonal variety, a highly productive hybrid resistant to Moniliophthora perniciosa and Phytophthora spp., was investigated. The natural cocobiota involved in the spontaneous fermentation of this hybrid in southern Brazil, was investigated by using both a culture-dependent microbiological analysis and a molecular analysis. The changes in the physicochemical characteristics and the kinetics of substrate utilization and metabolite production during fermentation were also evaluated. RESULTS: Yeasts (178) and bacteria (244) isolated during fermentation were identified by partial sequencing of the ITS and 16S rDNAs, respectively. After 144 h of fermentation, the indigenous yeast community was composed of Hanseniaspora spp., Saccharomyces spp., and Pichia spp. The bacterial population comprised Lactococcus spp., Staphylococcus spp., Acetobacter spp. and Lactobacilli strains. The kinetics of substrate transformation reflected the dynamic composition of the cocobiota. Substrates such as glucose, fructose, sucrose, and citric acid, present at the beginning of fermentation, were metabolized to produce ethanol, acetic acid, and lactic acid. CONCLUSION: The results described here provide new insights into microbial diversity in cocoa bean-pulp mass fermentation and the kinetics of metabolites synthesis, and pave the way for the selection of starter cultures to increase efficiency and consistency to obtain homogeneous and best quality cocoa products.

PMID- 29577312 TI - Rapid prediction of deoxynivalenol contamination in wheat bran by MOS-based electronic nose and characterization of the relevant pattern of volatile compounds. AB - BACKGROUND: Deoxynivalenol (DON) is a mycotoxin, mainly produced by Fusarium sp., most frequently occurring in cereals and cereal-based products. Wheat bran refers to the outer layers of the kernel, which has a high risk of damage due to chemical hazards, including mycotoxins. Rapid methods for DON detection in wheat bran are required. RESULTS: A rapid screening method using an electronic nose (e nose), based on metal oxide semiconductor sensors, has been developed to distinguish wheat bran samples with different levels of DON contamination. A total of 470 naturally contaminated wheat bran samples were analyzed by e-nose analysis. Wheat bran samples were divided in two contamination classes: class A ([DON] <= 400 ug kg-1 , 225 samples) and class B ([DON] > 400 ug kg-1 , 245 samples). Discriminant function analysis (DFA) classified wheat bran samples with good mean recognizability in terms of both calibration (92%) and validation (89%). A pattern of 17 volatile compounds of wheat bran samples that were associated (positively or negatively) with DON content was also characterized by HS-SPME/GC-MS. CONCLUSIONS: These results indicate that the e-nose method could be a useful tool for high-throughput screening of DON-contaminated wheat bran samples for their classification as acceptable / rejectable at contamination levels close to the EU maximum limit for DON, reducing the number of samples to be analyzed with a confirmatory method.

AB - : Coffee is one of the most widely consumed beverages in the world and contains numerous phytochemicals that are beneficial to consumer health. The phytochemical profile of coffee, however, can be affected by the roast level. In this study, we compared the effect of roasting level on the growth inhibitory activity of HT-29 (colon) and SCC-25 (oral) cancer cell lines. The different roasting stages selected for this study were green, cinnamon/blonde, city/medium, full city/medium-dark, and full city plus/dark. Cancer cells were treated with various concentrations of coffee extracts for 72 hr. Cell viability was quantified using the thiazolyl blue tetrazolium bromide assay. It was found that the lighter roast extracts, Cinnamon in particular, reduced cell growth more than darker roast extracts. The Cinnamon extract had the greatest amount of total phenolic content and antioxidant activity. Relative levels of gallic, caffeic, and chlorogenic acid in the extracts were also compared. The Cinnamon coffee extract had the highest levels of gallic and caffeic acids, which have both been widely-regarded as bioactive phytochemicals. In conclusion, the consumption of lighter roasted coffee, may contribute to the prevention of certain types of cancer such as oral and colon. PRACTICAL APPLICATION: Chemical compounds in coffee may reduce the risk for certain types of cancers. These compounds may be particularly abundant in lighter roasted coffee. Therefore, lighter roasted coffee could contribute to the prevention of cancer through a healthy diet. PMID- 29577315 TI - The RecQ-like helicase HRQ1 is involved in DNA crosslink repair in Arabidopsis in a common pathway with the Fanconi anemia-associated nuclease FAN1 and the postreplicative repair ATPase RAD5A. AB - RecQ helicases are important caretakers of genome stability and occur in varying copy numbers in different eukaryotes. Subsets of RecQ paralogs are involved in DNA crosslink (CL) repair. The orthologs of AtRECQ2, AtRECQ3 and AtHRQ1, HsWRN, DmRECQ5 and ScHRQ1 participate in CL repair in their respective organisms, and we aimed to define the function of these helicases for plants. We obtained Arabidopsis mutants of the three RecQ helicases and determined their sensitivity against CL agents in single- and double-mutant analyses. Only Athrq1, but not Atrecq2 and Atrecq3, mutants proved to be sensitive to intra- and interstrand crosslinking agents. AtHRQ1 is specifically involved in the repair of replicative damage induced by CL agents. It shares pathways with the Fanconi anemia-related endonuclease FAN1 but not with the endonuclease MUS81. Most surprisingly, AtHRQ1 is epistatic to the ATPase RAD5A for intra- as well as interstrand CL repair. We conclude that, as in fungi, AtHRQ1 has a conserved function in DNA excision repair. Additionally, HRQ1 not only shares pathways with the Fanconi anemia repair factors, but in contrast to fungi also seems to act in a common pathway with postreplicative DNA repair.

AB - BACKGROUND: A total of 60 three-way crossbred (Landrace, Duroc, and Yorkshire) pigs were divided into two groups (processed sulfur-fed pigs (SFPs) and nonprocessed sulfur-fed pigs, (NSFPs)) and used to determine the effect of supplementation with 3 g kg-1 processed sulfur on water-soluble precursors, free amino acids, and taste of meat using an electronic tongue, during refrigerated storage. RESULTS: Glycogen and glucose levels of SFP were significantly higher than in NSFPs. Glycogen levels decreased and glucose levels increased during storage (P < 0.001). The pH and moisture content of SFPs were higher than in NSFPs. Inosine of SFPs was higher than in NSFPs (P < 0.05). Hence, umami and richness tastes of SFPs were higher than in NSFPs and increased during storage. The total free amino acid content of both groups was not different, although it increased during storage (P < 0.001). The umami taste of water-soluble precursors was improved in meat derived from SFPs during refrigeration. CONCLUSION: The storage time and dietary supplementation with processed sulfur increased the taste components of meat. Application of an electronic tongue system can be used to distinguish the taste characteristics of different types of pork, based on differential supplementation and aging.

PMID- 29577317 TI - Arabidopsis thaliana SOBER1 (SUPPRESSOR OF AVRBST-ELICITED RESISTANCE 1) suppresses plant immunity triggered by multiple bacterial acetyltransferase effectors. AB - Plants evolved disease resistance (R) proteins that recognize corresponding pathogen effectors and activate effector-triggered immunity (ETI). However, it is largely unknown why, in some cases, a suppressor of ETI exists in plants. Arabidopsis SOBER1 (Suppressor of AvrBsT-elicited Resistance 1) was identified previously as a suppressor of Xanthomonas acetyltransferase effector AvrBsT triggered immunity. Nevertheless, the extent to which SOBER1 suppresses ETI is unclear. Here, we identified SOBER1 as a suppressor of Pseudomonas acetyltransferase effector HopZ5-triggered immunity in Arabidopsis using recombinant inbred lines. Further analysis showed that SOBER1 suppresses immunity triggered by multiple bacterial acetyltransferases. Interestingly, SOBER1 interferes with the immunity signalling activated by some but not all tested acetyltransferase effectors, indicating that SOBER1 might target components that are shared between several ETI pathways. PMID- 29577318 TI - Mental disorders in chronic obstructive pulmonary diseases. AB - PURPOSE: Anxiety and depression are underdiagnosed in chronic obstructive pulmonary disease (COPD) patients. Few studies have tried to identify their association with hospitalization (severe exacerbation). The objective of this study was to determine whether the anxiety/depression was associated with severe exacerbation. DESIGN AND METHODS: A prospective cohort study, based on a sample of 512 patients diagnosed with COPD originating from primary care in a rural area in Lleida (Spain) and monitored between November 1, 2012 and October 31, 2014. For each patient, variables of interest were recorded; they were administered the HADS (Hospital Anxiety and Depression Scale) test to determine the possible presence of anxiety/depression, and its association with severe exacerbation was analyzed using a logistic regression model. FINDINGS: Initially, the prevalence of anxiety/depression was 15.6%. The incidence of global hospitalization in the first year was 8.2% and 11.3% in the second year. In patients with anxiety/depression, it increased to 17.5% in the first year and 18.8% in the second year. In the multivariate regression model, the diagnosis of anxiety/depression almost doubled the risk of hospitalization (OR = 1.94) (p < .041). PRACTICE IMPLICATIONS: Anxiety and depression are associated with an increased risk of hospitalization. Intervention studies are needed to evaluate the effects of anxiety/depression in the hospitalization. PMID- 29577319 TI - El Nino drought increased canopy turnover in Amazon forests. AB - Amazon droughts, including the 2015-2016 El Nino, may reduce forest net primary productivity and increase canopy tree mortality, thereby altering both the short- and the long-term net forest carbon balance. Given the broad extent of drought impacts, inventory plots or eddy flux towers may not capture regional variability in forest response to drought. We used multi-temporal airborne Lidar data and field measurements of coarse woody debris to estimate patterns of canopy turnover and associated carbon losses in intact and fragmented forests in the central Brazilian Amazon between 2013-2014 and 2014-2016. Average annualized canopy turnover rates increased by 65% during the drought period in both intact and fragmented forests. The average size and height of turnover events was similar for both time intervals, in contrast to expectations that the 2015-2016 El Nino drought would disproportionally affect large trees. Lidar-biomass relationships between canopy turnover and field measurements of coarse woody debris were modest (R2 ~ 0.3), given similar coarse woody debris production and Lidar-derived changes in canopy volume from single tree and multiple branch fall events. Our findings suggest that El Nino conditions accelerated canopy turnover in central Amazon forests, increasing coarse woody debris production by 62% to 1.22 Mg C ha 1 yr-1 in drought years . PMID- 29577320 TI - Correlated seed failure as an environmental veto to synchronize reproduction of masting plants. AB - Variable, synchronized seed production, called masting, is a widespread reproductive strategy in plants. Resource dynamics, pollination success, and, as described here, environmental veto are possible proximate mechanisms driving masting. We explored the environmental veto hypothesis, which assumes that reproductive synchrony is driven by external factors preventing reproduction in some years, by extending the resource budget model of masting with correlated reproductive failure. We ran this model across its parameter space to explore how key parameters interact to drive seeding dynamics. Next, we parameterized the model based on 16 yr of seed production data for populations of red (Quercus rubra) and white (Quercus alba) oaks. We used these empirical models to simulate seeding dynamics, and compared simulated time series with patterns observed in the field. Simulations showed that resource dynamics and reproduction failure can produce masting even in the absence of pollen coupling. In concordance with this, in both oaks, among-year variation in resource gain and correlated reproductive failure were necessary and sufficient to reproduce masting, whereas pollen coupling, although present, was not necessary. Reproductive failure caused by environmental veto may drive large-scale synchronization without density dependent pollen limitation. Reproduction-inhibiting weather events are prevalent in ecosystems, making described mechanisms likely to operate in many systems. PMID- 29577321 TI - Is mepivacaine as effective as lidocaine during inferior alveolar nerve blocks in patients with symptomatic irreversible pulpitis? A systematic review and meta analysis. AB - This study aimed to compare the effectiveness of mepivacaine and lidocaine for pulpal anaesthesia and pain control when administered via an inferior alveolar nerve block during the root canal treatment of mandibular molars in patients with symptomatic irreversible pulpitis. A research protocol was developed and registered in PROSPERO. The systematic search was conducted during May 2017 in eight databases. The studies were selected based on inclusion and exclusion criteria. Two examiners analysed the sample independently, decided the eligibility for inclusion and classified the articles according to their quality. Statistical analysis was performed with Mantel-Haenszel and I-square (I2 ) tests considering a confidence interval of 95%. The initial sample consisted of 1130 articles, out of which four were eligible. The articles were published between 1993 and 2016. For both pulpal anaesthesia and pain control, there was no significant difference between mepivacaine and lidocaine (P = 0.843, I2 = 0%, and P = 0.183, I2 = 21.1%, respectively). Mepivacaine and lidocaine were similarly effective for pulpal anaesthesia and pain control after inferior alveolar nerve blocks for root canal treatment. PMID- 29577322 TI - Detecting oropharyngeal carcinoma using multispectral, narrow-band imaging and machine learning. AB - OBJECTIVE: To determine if multispectral narrow-band imaging (mNBI) can be used for automated, quantitative detection of oropharyngeal carcinoma (OPC). STUDY DESIGN: Prospective cohort study. METHODS: Multispectral narrow-band imaging and white light endoscopy (WLE) were used to examine the lymphoepithelial tissues of the oropharynx in a preliminary cohort of 30 patients (20 with biopsy-proven OPC, 10 healthy). Low-level image features from five patients were then extracted to train naive Bayesian classifiers for healthy and malignant tissue. RESULTS: Tumors were classified by color features with 65.9% accuracy, 66.8% sensitivity, and 64.9% specificity under mNBI. In contrast, tumors were classified with 52.3% accuracy (P = 0.0108), 44.8% sensitivity (P = 0.0793), and 59.9% specificity (P = 0.312) under WLE. Receiver operating characteristic analysis yielded areas under the curve (AUC) of 72.3% and 54.6% for classification under mNBI and WLE, respectively (P = 0.00168). For classification by both color and texture features, AUC under mNBI increased (80.1%, P = 0.00230) but did not improve under WLE (below 55% for both models, P = 0.180). Cross-validation with five folds yielded an AUC above 80% for both mNBI models and below 55% for both WLE models (P = 0.0000410 and 0.000116). CONCLUSION: Compared to WLE, mNBI significantly enhanced the performance of a naive Bayesian classifier trained on low-level image features of oropharyngeal mucosa. These findings suggest that automated clinical detection of OPC might be used to enhance surgical vision, improve early diagnosis, and allow for high-throughput screening. LEVEL OF EVIDENCE: NA.

Three key challenges 1177 IV. Conclusions 1181 Acknowledgements 1182 References 1183 SUMMARY: The origin and rapid diversification of angiosperms (flowering plants) represent one of the most intriguing topics in evolutionary biology. Despite considerable progress made in complementary fields over the last two decades (paleobotany, phylogenetics, ecology, evo-devo, genomics), many important questions remain. For instance, what has been the impact of mass extinctions on angiosperm diversification? Are the angiosperms an adaptive radiation? Has morphological evolution in angiosperms been gradual or pulsed? We propose that the recent and ongoing revolution in macroevolutionary methods provides an unprecedented opportunity to explore long-standing questions that probably hold important clues to understand present-day biodiversity. We present six key questions that explore the origin and diversification of angiosperms. We also identify three key challenges to address these questions: (1) the development of new integrative models that include diversification, multiple intrinsic and environmental traits, biogeography and the fossil record all at once, whilst accounting for sampling bias and heterogeneity of macroevolutionary processes through time and among lineages; (2) the need for large and standardized synthetic databases of morphological variation; and (3) continuous effort on sampling the fossil record, but with a revolution in current paleobotanical practice. PMID- 29577324 TI - Transfusion of autologous extracellular vesicles from stored red blood cells does not affect coagulation in a model of human endotoxemia. AB - BACKGROUND: Red blood cell (RBC) transfusion has been related to thromboembolic events. Microvesicles in the RBC product may support coagulation because they have procoagulant effects in vitro. We investigated whether transfusion of RBCs containing extracellular vesicles promotes coagulation in human recipients. As transfusion is mostly administered to ill patients, we used a model of endotoxemia. STUDY DESIGN AND METHODS: Eighteen healthy volunteers were randomized to receive either saline or fresh (2 days stored) or stored autologous (35 days stored) RBC transfusion (Dutch Trial Register: NTR4455). Two hours after infusion of lipopolysaccharide (LPS, from Escherichia coli, 2 ng/kg body weight), subjects received either saline or fresh or stored RBCs. Blood was sampled every 2 hours up to 8 hours after LPS infusion. Vesicles were measured with a flow cytometer (A50-Micro, Apogee Flow Systems). RESULTS: LPS resulted in increased thrombin generation compared to baseline. During storage, the total number of extracellular vesicles increased from 1.4 * 108 /mL (interquartile range [IQR], 8.3 * 107 -1.9 * 108 /mL) in the fresh product to 1.7 * 1010 /mL (IQR, 7.9 * 109 2.3 * 1010 /mL; p < 0.01) in the stored product (p < 0.001). Vesicles appeared to be mostly RBC derived. CONCLUSION: After transfusion, extracellular vesicles from stored RBC products, but not from fresh products, could be detected in the circulation of healthy volunteers. However, infusion of stored RBC extracellular vesicles did not augment thrombin generation compared to endotoxemic controls. Also, levels of d-dimer and thrombin-antithrombin complex were unaffected. In conclusion, transfusion of autologous RBCs containing high levels of extracellular vesicles does not enhance coagulation in human volunteers with endotoxemia. PMID- 29577325 TI - Increased transpiration is correlated with reduced boron deficiency symptoms in the maize tassel-less1 mutant. AB - Loss-of-function mutations of the tassel-less1 (tls1) gene in maize, which is the co-ortholog of the Arabidopsis boron (B) importer NIP5;1, leads to the loss of reproductive structures (tassels and ears). The tls1 phenotypes can be rescued by B supplementation in the field and in the greenhouse. As the rescue with B supplementation is variable in the field, we investigated additional abiotic factors, potentially causing this variation in controlled greenhouse conditions. We found that the B-dependent rescue of the tls1 mutant tassel phenotype was enhanced when plants were grown with a mix of high pressure sodium (HPS) and metal halide (MH) lamps. Normal and tls1 plants had a significant increase in transpiration and increased B content in the leaves in the greenhouse with the addition of MH lamps. Our findings imply that B transport to the shoot is enhanced through increased transpiration, which suggests that the xylem transpiration stream provides a significant supply of B in maize. PMID- 29577326 TI - A Feasibility Trial of Mental Health First Aid First Nations: Acceptability, Cultural Adaptation, and Preliminary Outcomes. AB - The Mental Health First Aid First Nations course was adapted from Mental Health First Aid Basic to create a community-based, culturally safe and relevant approach to promoting mental health literacy in First Nations contexts. Over 2.5 days, the course aims to build community capacity by teaching individuals to recognize and respond to mental health crises. This feasibility trial utilized mixed methods to evaluate the acceptability, cultural adaptation, and preliminary effectiveness of MHFAFN. Our approach was grounded in community-based participatory research principles, emphasizing relationship-driven procedures to collecting data and choice for how participants shared their voices. Data included participant interviews (n = 89), and surveys (n = 91) from 10 groups in four provinces. Surveys contained open-ended questions, retrospective pre-post ratings, and a scenario. We utilized data from nine facilitator interviews and 24 facilitator implementation surveys. The different lines of evidence converged to highlight strong acceptability, mixed reactions to the cultural adaptation, and gains in participants' knowledge, mental health first aid skill application, awareness, and self-efficacy, and reductions in stigma beliefs. Beyond promoting individual gains, the course served as a community-wide prevention approach by situating mental health in a colonial context and highlighting local resources and cultural strengths for promoting mental well-being. PMID- 29577327 TI - Gamma and infra-slow oscillations shape neuronal firing in the rat subcortical visual system. AB - KEY POINTS: Neuronal oscillations observed in sensory systems are physiological carriers of information about stimulus features. Rhythm in the infra-slow range, originating from the retina, was previously found in the firing of subcortical visual system nuclei involved in both image and non-image forming functions. The present study shows that the firing of neurons in the lateral geniculate nucleus is also governed by gamma oscillation (~35 Hz) time-locked to high phase of infra slow rhythm that codes the intensity of transient light stimulation. We show that both physiological rhythms are synchronized within and between ipsilateral nuclei of the subcortical visual system and are dependent on retinal activity. The present study shows that neurophysiological oscillations characterized by various frequencies not only coexist in the subcortical visual system, but also are subjected to complex interference and synchronization processes. ABSTRACT: The physiological function of rhythmic firing in the neuronal networks of sensory systems has been linked with information coding. Also, neuronal oscillations in different frequency bands often change as a signature of brain state or sensory processing. Infra-slow oscillation (ISO) in the neuronal firing dependent on the retinal network has been described previously in the structures of the subcortical visual system. In the present study, we show for the first time that firing of ISO neurons in the lateral geniculate nucleus is also characterized by a harmonic discharge pattern (i.e. action potentials are separated by the intervals governed by fundamental frequency in the gamma range: ~35 Hz). A similar phenomenon was recently described in the suprachiasmatic nuclei of the hypothalamus: the master biological clock. We found that both gamma and ISO rhythms were synchronized within and between ipsilateral nuclei of the subcortical visual system and were dependent on the retinal activity of the contralateral eye. These oscillatory patterns were differentially influenced by transient and prolonged light stimulation with respect to both frequency change direction and sustainability. The results of the present study show that the firing pattern of neurons in the subcortical visual system is shaped by oscillations from infra-slow and gamma frequency bands that are plausibly generated by the retinal network. Additionally, the results demonstrate that both rhythms are not a distinctive feature of image or non-image forming visual systems but, instead, they comprise two channels carrying distinctive properties of photic information. PMID- 29577328 TI - Calcium in drinking water: effect on iron stores in Danish blood donors-results from the Danish Blood Donor Study. AB - BACKGROUND: Studies confirm that calcium inhibits iron absorption. Danish tap water comes from groundwater, which contains varying amounts of calcium depending on the subsoil. We investigated the association of calcium in drinking water with iron levels in Danish blood donors. STUDY DESIGN AND METHODS: We used data on Danish blood donors including dietary and lifestyle habits, blood donation history, and physiologic characteristics including measures of ferritin levels along with information on area of residence from The Danish Blood Donor Study. Data on calcium levels in groundwater ("water hardness") were obtained through the Geological Survey of Denmark and Greenland. We performed multiple linear and logistic regression analyses to evaluate the effect of water hardness on ferritin levels and risk of having iron deficiency (defined as ferritin levels <15 ng/mL), stratified by sex. RESULTS: There was a significant negative association between water hardness and ferritin levels in both men and women. Risk of iron deficiency was correspondingly increased in both men (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.14-2.12) and women (OR, 1.20; 95% CI, 1.03-1.40) with increasing water hardness. In analyses restricted to individuals who received supplemental iron tablets no significant association between groundwater hardness and ferritin levels was observed. CONCLUSIONS: As measured by ferritin levels, residential drinking water calcium content is associated with blood donors- iron levels and risk of iron deficiency. However, effect sizes are small. PMID- 29577329 TI - Who victimizes whom and who defends whom? A multivariate social network analysis of victimization, aggression, and defending in early childhood. AB - The aim of this research was to investigate the interplay between victim aggressor relationships and defending relationships in early childhood to test the proposition that young aggressors are less selective than older children in their choice of vulnerable targets. Cross-sectional multivariate statistical social network analyses (Exponential Random Graph Models) for a sample of 177 preschoolers from seven classes, 5- to 7-years-old, revealed that boys were more aggressive than girls, toward both boys and girls, whereas defending relationships were most often same-sex. There was significant reciprocity in aggression, indicating that it was more often bidirectional rather than unidirectional. In addition, aggressors clearly defended each other when they shared their targets of aggression, whereas a marginally significant trend appeared for defending between victims who were victimized by the same aggressors. Furthermore, teacher-rated dominance was positively associated with children's involvement in both aggression and victimization, and teacher-rated insecurity was associated with less aggression, but not with victimization. These findings suggest that those who are reported as being victimized may retaliate, or be aggressive themselves, and do not display some of the vulnerabilities reported among older groups of victims. The findings are in line with the proposition that young aggressors are less strategic than older children in targeting vulnerable victims. The network approach to peer victimization and defending contributes to understanding the social processes facilitating the development of aggression in early childhood. PMID- 29577330 TI - Technical Note: Impact of region of interest size and location in Gafchromic film dosimetry. AB - PURPOSE: To evaluate dependence of measured dose on size and location of region of interest (ROI) in Gafchromic EBT3 film dosimetry. METHODS: Gafchromic EBT3 films were irradiated perpendicularly using the 6MV beam from a linear accelerator at 10 cm depth (100 cm SSD) of a 30 * 30 * 20 cm3 solid water phantom for a range of field sizes of 6 * 6 to 100 * 100 mm2 . ImageJ software was used for reading pieces of film. The appropriate location of ROIs in scanned films was found by two methods. First, the ROI was visually placed at the center of image. Second, the profile of pixel value versus distance was plotted and the center of profile was used for drawing ROI. Each scanned film was read using both methods and for three ROI sizes (1, 2, and 4 mm). A plastic scintillator, Exradin W1, was used as the reference dosimeter. RESULTS: Comparing the three ROI sizes using both methods showed that there was less than 2% difference from reference in output factor measurements for field sizes larger or equal to 10 * 10 mm2 . The percentage differences were increased in field sizes smaller than 10 * 10 mm2 and for ROI size of 4 * 4 mm2 for both centered-ROI and profiled-ROI methods. The mean percentage differences from reference measurements, for field sizes of 100 * 100 to 20 * 20 mm2 , were smaller than 1% in both methods of ROI positioning. For field sizes of 15 * 15 and 10 * 10 mm2 , the smaller mean percentage differences were observed in profiled-ROI (4 * 4 mm2 ) and centered-ROI (4 * 4 mm2 ). For the field sizes of 8 * 8 and 6 * 6 mm2 , the profiled-ROI (2 * 2 mm2 ) had smallest mean percentage difference, which was 0.88%. CONCLUSION: The ROI size of 4 * 4 mm2 is appropriate for dose measurements in field sizes of 100 * 100 mm2 to 10 * 10 mm2 , regardless of the method of finding location of ROI. In field sizes smaller than 10 * 10 mm2 , finding location of the ROI by profile of pixel values increases the accuracy of measurement, and ROI size of 2 * 2 mm2 has the smallest difference from the reference dose measurements.

AB - Creativity has been defined as the ability to produce output that is novel, useful, beneficial, and desired by an audience. But what is musical creativity, and relatedly, to what extent does creativity depend on domain-general or domain specific neural and cognitive processes? To what extent can musical creativity be taught? To answer these questions from a reductionist scientific approach, we must attempt to isolate the creative process as it pertains to music. Recent work in the neuroscience of creativity has turned to musical improvisation as a window into real-time musical creative process in the brain. Here, I provide an overview of recent research in the neuroscience of musical improvisation, especially focusing on multimodal neuroimaging studies. This research informs a model of creativity as a combination of generative and reactive processes that coordinate their functions to give rise to perpetually novel and aesthetically rewarding improvised musical output. PMID- 29577332 TI - Human placental PPAR-gamma and SOX-2 expression in serologically proved toxoplasmosis. AB - To explore PPAR-gamma and SOX-2 transcription factors expression in placenta according to maternal anti-Toxoplasma gondii serological profile during pregnancy and pregnancy outcome. The study included 240 placentas, grouped according to IgM and IgG serostatus and then subgrouped according to pregnancy outcome that varied between miscarriages, premature labour, stillbirth and giving birth to CNS anomaly or apparently healthy neonates. Samples were H&E stained and histopathologically scored blindly. PPAR-gamma expression was measured by ELISA, while SOX-2-positive nuclei were stained immunohistochemically to be calculated by ImageJ. The mean pathological score was significantly higher in IgM+ve and IgG rising than IgG-ve and persistent low groups. Former groups showed significantly higher PPAR-gamma (mean = 258.63, 227.11). However, PPAR-gamma was higher in apparently healthy neonate subgroups. SOX-2 was significantly lower in IgM+ve and IgG rising groups (mean = 12.87, 43.13) and associated with obvious fibrosis. SOX 2 lowest count was in CNS anomaly subgroup. PPAR-gamma and SOX-2 changes may give clues of how Toxoplasma induces pathogenesis during vertical transmission. Triggering PPAR-gamma expression may be a tool to downregulate the inflammatory response and establish a metabolically permissive cellular environment for Toxoplasma persistence. Low SOX-2 is suspected to disturb placental mesenchymal stem cells pluripotency and neuroectoderm development. PMID- 29577333 TI - NP30 stimulates Th17 differentiation through DC in Schistosomiasis Japonicum. AB - The murine monoclonal anti-idiotypic antibody, NP30, is a potential vaccine candidate against Schistosoma japonicum. Previous studies have revealed that NP30 has an immunoregulatory effect, but the underlying mechanism for this effect remains unknown. This study shows that NP30 induces dendritic cell (DC) maturation and increases the production of pro-inflammatory cytokines. The expression of CD86 and MHC II was upregulated in DCs following stimulation with NP30 in vitro. Moreover, NP30 induced Th17 polarization by increasing the production of IL-6 and TGF-beta. In vivo, Th17 differentiation was induced by the production of key pro-inflammatory cytokines, including IL-6and TGF-beta, from DCs of NP30-immunized mice. These results indicate that NP30 promotes Th17 polarization through DC activation, preventing serious schistosomiasis. PMID- 29577334 TI - Ecological Networks and Community Attachment and Support Among Recently Resettled Refugees. AB - Interventions aimed at enhancing mental health are increasingly centered around promoting community attachment and support. However, few have examined and tested the specific ecological factors that give rise to these key community processes. Drawing from insights from the ecological network perspective, we tested whether spatial and social overlap in routine activity settings (e.g., work, school, childcare) with fellow ethnic community members is associated with individuals' attachment to their ethnic communities and access to social resources embedded in their communities. Data on routine activity locations drawn from the Refugee Well Being Project (based in a city in the Southwestern United States) were used to reconstruct the ecological networks of recently resettled refugee communities, which were two-mode networks that comprise individuals and their routine activity locations. Results indicated that respondents' community attachment and support increased with their ecological network extensity-which taps the extent to which respondents share routine activity locations with other community members. Our study highlights a key ecological process that potentially enhances individuals' ethnic community attachment that extends beyond residential neighborhoods. PMID- 29577336 TI - Delayed-type allergy to cobalt-comparison of a flow cytometric lymphocyte proliferation test with patch testing. AB - BACKGROUND: The patch test is the standard procedure for diagnosing delayed-type sensitization. If a patch test is not possible, the flow cytometric lymphocyte proliferation test (LPT), which determines the number and type of cells responding to a specific antigen in vitro, might be considered as an alternative. OBJECTIVES: Our aim was to establish a flow cytometric LPT for the detection of delayed-type allergic responses to cobalt, and to determine the correlation between stimulation indices (SIs) in LPT and the grade of patch test reactions. With the patch test as a diagnostic reference, we also assessed the sensitivity and specificity of the LPT. METHODS: Fifty-four patients patch tested with the baseline series including cobalt (CoCl2 ) were additionally tested with the flow cytometric LPT with CoCl2 . RESULTS: There was a significant correlation between the results of both tests: rs = 0.43; P = .001. The LPT with CoCl2 showed a sensitivity of 52.6% and a specificity of 85.7%. Corresponding to the low sensitivity of the LPT, high likelihood ratios for a positive patch test reaction were reached only in cases of strong lymphocyte proliferation (SI >= 10). CONCLUSIONS: In cases of clearly increased SIs, the flow cytometric LPT with CoCl2 gives relevant diagnostic information, and represents a valuable alternative to patch testing. PMID- 29577335 TI - Evaluation of postharvest calcium treatment and biopreservation with Lactobacillus rhamnosus GG on the quality of fresh-cut 'Conference' pears. AB - BACKGROUND: Biological preservation with probiotic bacteria has arisen as an alternative to control the growth of foodborne pathogens on food. The objective of this work was to evaluate the effect of postharvest calcium application and biopreservation with Lactobacillus rhamnosus GG on the quality and bioaccessibility of total phenolic content and antioxidant activity in fresh-cut pears. RESULTS: The immersion of whole pears in a calcium chloride solution did not provide added value. Despite the increase in observed activity of PME and PPO enzymes in fresh-cut pears during storage, the browning index and firmness values were constant for all samples. The antioxidant properties, including antioxidant activity, total phenolic content and vitamin C content, were maintained during storage, but a significant decrease was observed after in vitro simulated digestion. Ca/LGG samples showed the lowest calcium content (1.75 +/- 0.00 g kg-1 ) after 9 d of storage at 4 degrees C. In general, the overall visual quality scores were higher in fresh-cut pears treated with L. rhamnosus GG than in non treated pears, with the highest values in the NoCa/LGG (7.7 +/- 0.2) samples after 9 d at 4 degrees C. CONCLUSION: Fresh-cut pears with a postharvest treatment of calcium and immersed in a solution containing antioxidant agents and probiotic bacteria could be a suitable alternative to dairy products for maintaining the overall quality of fruit for up to 9 d of storage.

AB - PURPOSE: First measurements of the imaging performance of a novel prototype water equivalent electronic portal imaging device (EPID) designed for simultaneous imaging and dose verification in radiotherapy and previously characterized by our group for dosimetry are reported. Experiments were conducted to characterize the prototype's imaging performance relative to a standard commercial EPID and Monte Carlo (MC) simulations were performed to quantify the impact of several detector parameters on image quality and to inform the design of a proposed next generation prototype. METHODS: The prototype EPID utilizes an array of 3 cm long plastic-scintillating fibers in place of the metal plate/phosphor screen in standard EPIDs. Using a clinical 6 MV photon beam, the prototype's modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE) were measured and compared to measurements taken using a standard commercial EPID. A sensitivity analysis was then performed using the MC model by quantifying these metrics while varying the values of several geometrical and optical transport parameters that were unspecified by the prototype manufacturer. Finally, the MC model was used to quantify the imaging performance of a proposed next-generation prototype incorporating 1.5 cm long fibers that is better suited for integration with clinical portal imaging and dosimetry systems. RESULTS: The prototype EPID's zero spatial frequency DQE exceeded 3%, more than doubling that measured with the standard EPID (1.25%). This increased DQE was a consequence of using a prototype array detector with a greater equivalent thickness than the combined copper plate and phosphor screen in a standard EPID. The increased thickness of our prototype decreased spatial resolution relative to the standard EPID; however, the prototype EPID NPS was also lower than that measured with the standard EPID across all spatial frequencies. The sensitivity analysis demonstrated that the NPS was strongly affected by the roughness of the boundaries between fiber core and cladding regions. By comparison, the MTF was most sensitive to beam divergence and the presence of air between the fiber array and underlying photodiode panel. Simulations demonstrated that by optimizing these parameters, DQE(0) >4% may be achievable with the proposed next-generation prototype design. CONCLUSIONS: The first measurements characterizing the imaging performance of a novel water equivalent EPID for imaging and dosimetry in radiotherapy demonstrated a DQE(0) more than double that of a standard EPID. MC simulations further demonstrated the potential for developing a next-generation prototype better suited for clinical translation with even higher DQE.

AB - AIM: To assess the prevalence of frailty among patients who had cardiac resynchronization as well as the influence of frailty on the main endpoints during follow-up. METHODS: The study included 156 patients (aged 74.33 +/- 6.75; 27 W) with diagnosed heart failure who were hospitalized for the implantation of a cardiac resynchronization device. The Tilburg Frailty Indicator questionnaire was used to evaluate frailty syndrome. RESULTS: Frailty syndrome was diagnosed in 75.64% of patients who were included. The average value of frailty for the whole group was 6.21 +/- 1.94, for the physical domain 4.29 +/- 1.32, for the psychological domain 1.40 +/- 1.04, and for the social domain 0.51 +/- 0.57. During the follow-up period, 5.7% of the patients died, and the mortality rate was not statistically higher (P = 0.5795) among patients who were diagnosed with frailty syndrome (6.78%) compared to robust patients (2.63%). Analysis of the complications and first electrical storm episodes demonstrated that these events did not occur in patients with no identifiable frailty syndrome. These occurred at a rate of 4.24% (complications) and 2.54% (electric storm) in patients with frailty syndrome. CONCLUSIONS: Frailty syndrome can be an important predictor of negative outcomes in patients with heart failure who undergo cardiac resynchronizations. PMID- 29577338 TI - Technical Note: Single time point dose estimate for exponential clearance. AB - OBJECTIVE: Although personalized dosimetry may be desirable for radionuclide therapy treatments, the multiple time samples required to determine the total integrated activity puts a burden on patients and clinic resources. The aim of this paper is to demonstrate that when some prior knowledge is known about the tracer kinetic parameters, the total integrated activity (and thus radiation dose) can be estimated from a single time sample. METHODS: Mathematical derivations have been performed to generate equations for the total integrated activity in terms of a single time sample of activity for monoexponential and biexponential clearance. Simulations were performed using both exponential models where the rate constants and associated parameters were randomly sampled from distributions with a known mean. The actual total integrated activity for each random sample was compared with the estimated total integrated activity using the mean value of the parameters. Retrospective analysis of 90 Y DOTATOC data from a clinical trial provided a comparison of actual kidney dose with the estimated kidney dose using the single time point approach. RESULTS: The optimal sampling time for the single point approach was found to be equal to the mean time of the rate constant. The simulation results for the monoexponential and biexpoential models were similar. Regressions comparing the actual and estimated total integrated activity had very high correlations (r2 > 0.95) along with acceptable standard errors of estimate, especially at the optimal sampling point. The retrospective analysis of the 90 Y DOTATOC data also yielded similar results with an r2 = 0.95 and a standard error of estimate of 61 cGy. CONCLUSIONS: In situations where there is prior knowledge about the population averages of kinetic parameters, these results suggest that the single time point approach can be used to estimate the total integrated activity and dose with sufficient accuracy to manage radionuclide therapy. This will make personalized dosimetry much easier to perform and more available to the community. PMID- 29577340 TI - Safety and efficacy of apixaban versus warfarin in patients with end-stage renal disease: Meta-analysis. AB - BACKGROUND: At the present, apixaban is the only nonvitamin K oral anticoagulant approved by the Food and Drug Administration for use with patients with creatinine clearance <15 mL/min or end-stage renal disease (ESRD). However, the recommendations are based on pharmacokinetic and pharmacodynamic data and there was lack of clinical trial evidence. We aimed to assess safety and efficacy of apixaban in patients with advanced chronic kidney disease (CKD) or ESRD. METHODS: Databases were searched through November 2017. Studies that reported incidence or odd ratios of bleeding complications or thromboembolic events in the use of apixaban in patients with CKD stage 4-5 or ESRD on dialysis were included. Effect estimates from the individual study were extracted and combined using random effect, generic inverse variance method of DerSimonian and Laird. RESULTS: Five studies were included into the analysis consisting of 43,850 patients in observational cohort studies. The majority of patients (87%) used apixaban for atrial fibrillation. The pooled estimated incidence of any bleeding complications on apixaban was 17.4% (95% confidence interval [CI]: 13.0%-23.0%). Compared to warfarin, apixaban was significantly associated with reduced risk of major bleeding (pooled odds ratio [OR], 0.42; 95% CI, 0.28-0.61). In studies in ESRD patients on dialysis, the pooled OR of major bleeding was 0.27 (95% CI, 0.07 0.95). There was no significant difference in risk of thromboembolic events in advanced CKD or ESRD patients on apixaban versus vitamin K antagonists (pooled OR, 0.56; 95% CI, 0.23-1.39). CONCLUSIONS: Among patients with advanced CKD and ESRD, the use of apixaban was associated with lower risk of major bleeding compared to warfarin, and was found to be relatively effective with no excess risk of thromboembolic events. PMID- 29577341 TI - Impact of intraoperative mechanical ventilation on left ventricular lead function in cardiac resynchronization therapy. AB - BACKGROUND: Intraoperative controlled mechanical ventilation (CMV) changes the intrathoracic geometry and may impact postoperative left ventricular (LV) lead function after CRT implantation. This multicenter study investigates the effect of intraoperative ventilation setting (spontaneous breathing [SB] vs CMV) on postoperative LV lead function taking into account patients' body mass index (BMI). METHODS: CRT implantation was performed at two centers during SB in 92 and during CMV in 73 patients. Follow-up was carried out after 3 +/- 5 and 36 +/- 53 days. Functional lead parameters (FLP; pacing threshold and impedance), postoperative adverse events (A; phrenic nerve stimulation [PNS] and lead malfunction), and patients' BMI were assessed. Delta values of FLP between baseline and follow-up visits were analyzed applying an analysis of covariance model to detect subclinical alterations in LV lead function. RESULTS: AE occurred in a total of 36 (21%) patients. PNS was observed in 26 (15%) patients and LV lead repositioning due to malfunction was necessary in 10 (6%) patients. Both AE and FLP delta values between baseline and follow-up were not associated with intraoperative ventilation settings nor the patients' BMI. CONCLUSIONS: This study demonstrates that there is no impact of the intraoperative ventilation setting (SB vs CMV) on postoperative FLP or the occurrence of AE. This is also the case taking into account the BMI. With respect to these findings both approaches-sedation only or general anaesthesia including CMV-can be safely implemented during CRT implantation. PMID- 29577342 TI - System justification enhances well-being: A longitudinal analysis of the palliative function of system justification in 18 countries. AB - According to the palliative function of ideology hypothesis proposed by System Justification Theory, endorsing system-justifying beliefs is positively related to general psychological well-being, because this fulfils existential, epistemic, and relational needs. We discuss and address three main issues: (1) the role of societal inequality, (2) comparisons by social status, and (3) cross-sectional versus longitudinal research. We used a longitudinal survey of representative online samples (N = 5,901) from 18 countries. The results supported the main argument proposed by the theory, in that system justification was positively and significantly related to life satisfaction and negatively related to anxiety and depression. The pattern of results suggested that the palliative function of system justification is more homogeneously distributed across individual and collective measures of social status than proposed by the theory, because the function was unaffected either by society-level inequality or by individual-level social status. These results allow us to infer that one of the reasons for the high stability of social arrangements is located in the psychological domain of palliative effects. PMID- 29577343 TI - Perceptions of Housing and Shelter among People with Histories of Unstable Housing in three Cities in Canada: A Qualitative Study. AB - Housing is a key social determinant of health that contributes to the well documented relationship between socioeconomic status and health. This study explored how individuals with histories of unstable and precarious housing perceive their housing or shelter situations, and the impact of these settings on their health and well-being. Participants were recruited from the Health and Housing in Transition study (HHiT), a longitudinal, multi-city study that tracked the health and housing status of people with unstable housing histories over a 5 year period. For the current study, one-time semi-structured interviews were conducted with a subset of HHiT study participants (n = 64), living in three cities across Canada: Ottawa, Toronto, and Vancouver. The findings from an analysis of the interview transcripts suggested that for many individuals changes in housing status are not associated with significant changes in health due to the poor quality and precarious nature of the housing that was obtained. Whether housed or living in shelters, participants continued to face barriers of poverty, social marginalization, inadequate and unaffordable housing, violence, and lack of access to services to meet their personal needs. PMID- 29577344 TI - This corrosion: A systematic review of the association between alternative subcultures and the risk of self-harm and suicide. AB - BACKGROUND: Rates of self-harm and suicide are increasing in young people. The literature suggests that individuals who identify with alternative subcultures (e.g., Goth) may be at a greater risk. OBJECTIVE: To explore the prevalence of self-harm and suicide in alternative subcultures and the factors that might contribute to this increased risk. METHOD: Using a systematic strategy, the databases PsycINFO, Scopus, MEDLINE and Web of Science, and the E-Thesis online service (ETHOS) were searched for English language only papers, with no restrictions in terms of date of publication. Papers were selected that included data on the relationship between either alternative subculture identity (e.g., Goth) or preference for alternative music (e.g., Heavy Metal) and self-harm or suicide. Ten quantitative papers were included: seven cross-sectional, two longitudinal and one cross-sectional state-level comparison study. Two qualitative papers were also included. Studies were assessed by two reviewers for risk of bias. RESULTS: The findings indicated that individuals who associated with alternative subcultures were at a greater risk of self-harm and suicide. Whilst qualitative papers identified potential mechanisms (e.g., exposure to self harm and the way self-harm is presented or normalized), there remains limited support for these mechanisms. CONCLUSIONS: More research is required to understand the association between self-harm, suicide and alternative subculture affiliation, and the factors underlying it. Longitudinal studies and studies focusing on mechanism are particularly important. PRACTITIONER POINTS: The review supports the suggestion that those who identify as belonging to an alternative subculture may be at a higher risk of self-harm and suicidal behaviour. It also presents preliminary evidence that alternative affiliation predicts self-harm over time, and that this effect holds whilst adjusting for a number of likely confounders. The findings highlight the importance of increasing the awareness of the victimization and potential risk that these groups hold and suggests areas for intervention in health, educational, and social services. The review does not, however, indicate specifically what it is about alternative subculture affiliation (or alternative music preference) that could contribute to the risk of self-harm. Consequently, studies with a greater focus on mechanisms are needed. Methodological limitations (e.g., cross-sectional studies, small sample of 'alternative' participants, westernized samples) restricted the reliability and validity of the results which impacted on the extent to which the findings could be generalized more widely. PMID- 29577345 TI - Microtissue engineering root canal dentine with crosslinked biopolymeric nanoparticles for mechanical stabilization. AB - AIM: To evaluate the functional strain distribution pattern in root dentine following canal preparation and root canal surface engineering with crosslinked biopolymeric nanoparticles using digital moire interferometry (DMI). METHODOLOGY: Root dentine specimens were prepared, grating material replicated and tested for 10-50 N, compressive loads in a customized high-resolution, whole-field moire interferometry set-up. Digital moire fringes were acquired to determine the strain distribution pattern at specific regions of interest before and after canal enlargement, and dentine surface engineering with a chitosan nanoparticle crosslinker solution. Fringe patterns were acquired, and strain distribution pattern in the direction perpendicular to dentinal tubules (U-field) and parallel to dentinal tubules (V-field) was analysed with custom digital image-processing software. Data were analysed with a statistical method on trend analysis at 0.05 significant level. RESULTS: Distinct deformation patterns perpendicular to the dentinal tubules were observed in root dentine. Root canal dentine removal following instrumentation resulted in an increase in strain distribution, which increased with an increase in applied loads (P < 0.01). The root canal dentine engineered with crosslinked nanoparticles demonstrated a conspicuous decrease in previously increased strain distribution in both coronal and apical root dentine (P < 0.01). A significant increase in tensile strain in root dentine was observed subsequent to instrumentation in the direction parallel to dentinal tubules (P < 0.01). There was a significant reduction in the tensile strain formed at the apical region of the instrumented root dentine following crosslinked nanoparticle treatment (P < 0.05). CONCLUSIONS: This study highlighted the potential of root canal dentine microtissue engineering with crosslinked chitosan nanoparticle to improve radicular strain distribution patterns in instrumented canals. PMID- 29577346 TI - The impact of right ventricular function assessed by 2-dimensional speckle tracking echocardiography on early mortality in patients with inferior myocardial infarction. AB - BACKGROUND: Right ventricular (RV) involvement in inferior myocardial infarction (MI) increases in-hospital morbidity and mortality. HYPOTHESIS: RV systolic dysfunction assessed by 2-dimensional speckle tracking echocardiography (STE) might be a predictor of early mortality in patients with acute inferior MI. METHODS: Eighty-one consecutive patients with acute inferior MI (mean age, 60.8 +/- 12.7 years; 18 females) were included. RV myocardial involvement was defined as an elevation >1 mm in V1 or V4 R within 12 hours of symptom onset. RV function was assessed by STE. Patients were followed for 30 days for all-cause mortality. RESULTS: Thirty-eight patients had RV myocardial involvement, and they had significantly lower tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (RVS), and left ventricular (LV) and RV global longitudinal strain (GLS). Nine patients (11%) died within 30 days. The mean age of mortality group was higher with more female frequency. They had significantly higher pro-BNP, hs-troponin T, and creatinine levels, but lower hemoglobin levels. TIMI 3 flow was significantly less achieved in mortality group. RV myocardial involvement was more frequent in the mortality group, and they had significantly lower TAPSE, RVS, and LV and RV GLS. Multivariate analysis revealed that age and RV GLS were independent predictors of early mortality. RV GLS <= 14% predicted early mortality in patients with acute inferior MI with a sensitivity of 88.9% and a specificity of 62.5% (AUC: 0.817, P = 0.002). CONCLUSIONS: RV GLS may be useful in predicting early mortality in patients with acute inferior MI. PMID- 29577348 TI - Preoperative autologous blood collection before bone marrow harvests in haploidentical related donors: is it justified? AB - BACKGROUND: With the increasing safety of allogeneic blood supply and declining need for transfusion due to patient blood management, the practice of preoperative autologous donation (PAD) continues to decline. The practice gained popularity during the 1980s and 1990s with the emergence of transfusion transmitted human immunodeficiency virus and hepatitis C. At the peak of this public concern, the National Marrow Donor Program recommended that marrow donors have 1 to 3 autologous units of blood collected before their marrow harvest to minimize the likelihood of allogeneic transfusion. After three decades, the practice remains prevalent in marrow donors. We aimed to study the efficacy of PAD in healthy marrow donors. STUDY DESIGN AND METHODS: PADs performed before marrow harvest in healthy donors at our center between January 2013 and July 2015 were reviewed. The utilization of autologous units and decrease in hemoglobin levels due to PAD and marrow harvest were studied. Similar practices were assessed in the rest of the United States through a brief survey. RESULTS: Of a total of 262 autologous units collected from 136 donors, 25.2% were wasted. Ninety-nine percent of the marrow donors received at least 1 unit of blood irrespective of the need. PAD contributed to preoperative anemia, exposing three donors to allogeneic blood transfusion. The survey results showed a mixed response with some institutions continuing and others not practicing PAD. CONCLUSION: PADs are not justified in healthy marrow donors as they expose them to a risk of preoperative anemia and hence a greater risk of transfusion. PMID- 29577347 TI - Electrocardiographic predictors of validated right ventricular outflow tract septal pacing for correct localization of transthoracic echocardiography. AB - BACKGROUND: Electrocardiographic (ECG) characteristics of true right ventricular outflow tract (RVOT) septal pacing have not been clearly demonstrated. HYPOTHESIS: We hypothesized that ECG parameters would help operators differentiate true RVOT septum from non-septal septum. METHODS: We analyzed 151 patients who underwent pacemaker implantation with a ventricular lead in the RVOT. Transthoracic echocardiographic (TTE) determination of pacing sites was applied in all patients after implantation. A 12-lead ECG was recorded during forced ventricular pacing. RESULTS: According to TTE orientation, pacing at the RVOT septum was achieved in 94 patients (62.3%). Compared with nonseptal pacing, septal pacing had significantly shorter QRS duration (139.2 +/- 18.5 ms vs 155.5 +/- 14.7 ms; P < 0.001). More frequent negative or isoelectric QRS vector in lead I (76% vs 32%; P < 0.001), lead II/III R-wave amplitude ratio < 1 (52% vs 25%; P = 0.001), and aVR/aVL QS-wave amplitude ratio < 1 (59% vs 32%; P = 0.001) were observed in septal pacing. Transitional zone (TZ) score (3.8 +/- 0.96 vs 4.2 +/- 0.90; P = 0.004) and TZ index (0.3 +/- 0.5 vs 0.6 +/- 0.7; P = 0.008) were significantly lower in septal pacing than in nonseptal pacing, respectively. In multivariate analysis, paced QRS duration and negative or isoelectric QRS vector in lead I independently predicted RVOT septal pacing (P < 0.001). At ROC curve analysis, paced QRS duration <=145 ms identified RVOT septal pacing with 85.1% sensitivity and 78.9% specificity. CONCLUSIONS: This study reveals the heterogeneity of lead placement within the RVOT. Narrower paced QRS duration and negative or isoelectric QRS vector in lead I independently predict RVOT septal pacing. PMID- 29577349 TI - Natural history and clinical detection of undiagnosed coeliac disease in a North American community. AB - BACKGROUND: Coeliac disease is a substantially underdiagnosed disorder, with clinical testing currently guided by case finding. AIM: To determine the presence of indications for diagnostic testing and frequency of clinical testing in undiagnosed coeliac disease. METHODS: This was a case-control study of adults without prior diagnosis of coeliac disease. Undiagnosed cases were identified through sequential serology, and unaffected age- and gender-matched controls were selected. Medical records were systematically reviewed for indications for and evidence of clinical testing. RESULTS: Of 47 557 adults, 408 cases of undiagnosed coeliac disease were identified. 408 serology negative matched controls were selected. Eight-matched pairs were excluded, leading to 800 included individuals (61% female; median age 44.2 years). The odds of any indication for clinical testing were similar among undiagnosed coeliac disease and controls (odds ratio (OR) 1.18; 95% CI: 0.85-1.63, P = 0.32). Most individual indications were not associated with serologic status. Exceptions to this include hypothyroidism, which was more likely in cases of undiagnosed coeliac disease, and dyspepsia and chronic diarrhoea, which were less likely. Cases of undiagnosed coeliac disease were more likely to develop osteoporosis (P = 0.005), dermatitis herpetiformis (P = 0.006), chronic fatigue (P = 0.033), thyroiditis (P = 0.003), autoimmune diseases (P = 0.008), and have a family member diagnosed with coeliac disease (P = 0.001). CONCLUSION: This study strongly suggests that current case finding is not effective in detecting undiagnosed coeliac disease. Individuals with undiagnosed coeliac disease were more likely than controls to develop indications for testing overtime. A more effective method for detection of coeliac disease is needed. PMID- 29577350 TI - Anti-viral therapy can be delayed or avoided in a significant proportion of HBeAg negative Caucasian patients in the Grey Zone. AB - BACKGROUND: Grey Zone (GZ) is an ill-defined situation including patients falling between inactive carrier (IC) state and HBeAg-negative chronic hepatitis B (HBeAg negative CHB). AIMS: To assess the long-term outcomes of GZ patients compared to IC in the absence of treatment. METHODS: Retrospective analysis of 287 IC and GZ HBeAg-negative patients. Patients were classified into 4 groups at baseline: HBV DNA <2000 IU/mL and ALT <40 U/L (IC), HBV-DNA <2000 IU/mL and ALT 40-80 U/L (GZ 1), HBV-DNA 2000-20 000 IU/mL and ALT <40 U/L (GZ-2) or ALT 40-80 U/L (GZ-3). Data were also analysed using AASLD ALT criteria. RESULTS: After a median follow up of 8.2 (5-19) years, HBsAg loss occurred in about 15% ICs or GZ patients. Transition into IC state occurred in 40% of GZ patients. DNA fluctuations >2000 IU/mL correlated inversely with transition into IC and HBsAg loss. HBsAg levels were significantly lower in ICs than in GZ patients (338 IU/mL [20-3269] vs 5763 IU/mL [2172-17 754]; P < 0.05). Among the latter group, there was an increasing gradient of HBsAg levels from GZ-1 to GZ-3 patients (P < 0.05). HBeAg-negative CHB occurred in only 18 (6.3%) GZ patients. No patient developed cirrhosis nor advanced fibrosis. ALT/HBV-DNA fluctuations and HBeAg-negative CHB development were more frequent in genotype B/C patients, whereas HBsAg loss occurred only in genotype A/D patients. CONCLUSIONS: Most Caucasian GZ patients present excellent long-term outcomes in the absence of treatment, with a high rate of HBsAg loss and low rate of progression to HBeAg-negative CHB. HBV-genotyping and HBsAg levels could help to predict outcomes and better classify GZ patients. PMID- 29577352 TI - Retinoic acid and tracheal occlusion for diaphragmatic hernia treatment in rabbit fetuses. AB - INTRODUCTION: Lung hypoplasia and pulmonary arterial hypertension in congenital diaphragmatic hernia lead to a high perinatal mortality. Although sustained fetoscopic tracheal occlusion (TO) improves lung development, a major side effect is abnormal pneumocyte differentiation. This study evaluated the potential ability of intratracheal retinoic acid (RA) administration to reduce adverse effects of sustained TO in a rabbit model of diaphragmatic hernia. METHODS: A left diaphragmatic defect was created on day 23 in time-dated pregnant rabbits. On day 28, the same rabbits underwent sham surgery or TO, with an injection of empty or RA-loaded liposomes. On day 30, the fetuses were harvested, and the lungs were processed for histology, immunohistochemistry, and gene expression quantification. RESULTS: A tracheal RA injection at the time of TO had no effect on the lung-to-body-weight ratio, radial alveolar count or lung connective tissue composition. Retinoic acid plus TO had synergic effects on vascular measurements, proportional medial thickness, and endothelin-1 receptor type-A gene expression. The most noticeable effect was recovery of normal pneumocyte differentiation. CONCLUSION: Retinoic acid plus TO prevented abnormal pneumocyte differentiation and seemed to have a beneficial effect on pulmonary vascularization. PMID- 29577351 TI - A New Way to Treat Brain Tumors: Targeting Proteins Coded by Microcephaly Genes?: Brain tumors and microcephaly arise from opposing derangements regulating progenitor growth. Drivers of microcephaly could be attractive brain tumor targets. AB - New targets for brain tumor therapies may be identified by mutations that cause hereditary microcephaly. Brain growth depends on the repeated proliferation of stem and progenitor cells. Microcephaly syndromes result from mutations that specifically impair the ability of brain progenitor or stem cells to proliferate, by inducing either premature differentiation or apoptosis. Brain tumors that derive from brain progenitor or stem cells may share many of the specific requirements of their cells of origin. These tumors may therefore be susceptible to disruptions of the protein products of genes that are mutated in microcephaly. The potential for the products of microcephaly genes to be therapeutic targets in brain tumors are highlighted hereby reviewing research on EG5, KIF14, ASPM, CDK6, and ATR. Treatments that disrupt these proteins may open new avenues for brain tumor therapy that have increased efficacy and decreased toxicity. PMID- 29577353 TI - Determination of topiramate by capillary electrophoresis with capacitively coupled contactless conductivity detection: A powerful tool for therapeutic monitoring in epileptic patients. AB - Topiramate (TPM) is the main antiepileptic drug used for the control of partial and generalized seizures in both adults and children. In association with clinical observations, the analysis of plasmatic concentration of TPM is of utmost importance for the individual adjustment of the administered dose to the patient. In the present work, a bioanalytical method was developed and validated for TPM analysis in plasma samples by capillary electrophoresis with capacitively coupled contactless conductivity detection (CE-C4 D). A simple background electrolyte composed of 15 mmol/L triethylamine, hydrodynamic injections (0.8 psi for 5 s) and a moderate separation voltage (20 kV) were used, rendering relatively short analysis times (<3 min). The sample pre-treatment was carried out by liquid-liquid extraction using methyl terc-butyl ether as solvent and 200 MUL of plasma. The method was validated according to the official guidelines from the European Medicine Agency and showed linearity in plasmatic concentration range from 1 to 30 MUg/mL, which covers the clinically-relevant interval. The lower limit of quantification of 1 MUg/mL obtained also allows following patients with low dosage of the drug. The method was successfully applied to analysis of plasma samples and allowed the identification of 80% under-medicated patients in the analyzed patient pool. PMID- 29577354 TI - Sexual Portrait of Couples Seeking Relationship Therapy. AB - This study sought to provide information about the sexual well-being of 298 mixed sex couples seeking relationship therapy and determined the extent to which problems with sexual functioning and dyadic adjustment of both partners are associated with sexual satisfaction. Partners completed measures of dyadic adjustment, sexual satisfaction, and sexual functioning. Thirty percent of couples reported a clinically significant sexual problem. Compared to their male partners, the women were more likely to report a sexual problem as well as lower dyadic adjustment, sexual satisfaction, and overall sexual functioning. Path analysis indicated that relationship adjustment uniquely predicted individuals' own sexual satisfaction; problems in sexual functioning uniquely predicted own and partner sexual satisfaction. Findings underscore the need to address sexual problems in relationship therapy. PMID- 29577355 TI - Simultaneous determination of zidebactam and cefepime in dog plasma by LC-MS/MS and its application to pre-clinical pharmacokinetic study. AB - A precise and accurate liquid chromatography-tandem mass spectrometric (LC-MS/MS) bioanalytical method has been developed and validated for the simultaneous quantification of zidebactam (ZID) and cefepime (FEP) in dog plasma. Ceftazidime was used as an internal standard. Protein precipitation method was used as sample preparation approach. The calibration curve obtained was linear (r >= 0.99) over the concentration range 0.156-80 MUg/mL for ZID and 0.312-160 MUg/mL for FEP. The method was validated as per US Food and Drug Administration guidelines and the results met the acceptance criteria. A run time of 3.5 min for each sample made it possible to analyze the maximum number of samples per day. The proposed method was successfully applied for pharmacokinetic study in beagle dogs. PMID- 29577356 TI - Ser-486/491 phosphorylation and inhibition of AMPKalpha activity is positively associated with Gleason score, metastasis, and castration-resistance in prostate cancer: A retrospective clinical study. AB - BACKGROUND: We previously demonstrated that adenosine monophosphate-activated protein kinase (AMPKalpha) activity is significantly inhibited by Ser-486/491 phosphorylation in cell culture and in vivo models of metastatic and castration resistant prostate cancer, and hypothesized these findings may translate to clinical specimens. METHODS: In this retrospective, single-institution pilot study, 45 metastatic prostate cancer cases were identified within the University Hospitals Cleveland Medical Center Pathology Archive with both metastasis and matched primary prostate tumor specimens in formalin-fixed, paraffin-embedded blocks, and complete electronic medical records. Thirty non-metastatic, hormone dependent prostate cancer controls, who were progression-free as defined by undetectable prostate specific antigen for at least 79.6 months (range 79.6-136.0 months), and matched metastatic cases based on age, race, and year of diagnosis. All specimens were collected from 1991 to 2014; primary tumor specimens were obtained via diagnostic biopsy or prostatectomy, and metastasis specimens obtained via surgery or perimortem. 5-MU sequential slides were processed for phospho-Ser-486/491 AMPKalpha1 /alpha2 , phospho-Thr-172 AMPKalpha, AMPKalpha1 /alpha2 , phospho-Ser-792 Raptor, phospho-Ser-79 acetyl-CoA carboxylase, and phospho-Ser-872, 3-hydroxy-3-methylglutaryl-CoA reductase immunohistochemistry to determine expression, phosphorylation pattern, and activity of AMPKalpha. RESULTS: Increased inhibitory Ser-486/491 AMPKalpha1 /alpha2 phosphorylation, increased AMPKalpha protein expression, decreased AMPKalpha activity, and loss of nuclear AMPKalpha and p-AMPKalpha are associated with prostate cancer progression to metastasis. Increased p-Ser-486/491 AMPKalpha1 /alpha2 was also positively correlated with higher Gleason grade and progression to castration-resistance. CONCLUSIONS: p-Ser-486/491 AMPKalpha1 /alpha2 is a novel marker of prostate cancer metastasis and castration-resistance. Ser-486/491 phosphokinases should be pursued as targets for metastatic and castration-resistant prostate cancer chemotherapy.

AB - Frailty reflects a state of decreased physiological reserve and vulnerability to stressors. Its prevalence among patients with cardiovascular disease is as high as 60%. Frailty is associated with a poor prognosis for patients with heart failure, increasingly frequent hospitalization, and death. The recent published listing criteria for heart transplantation of the International Society for Heart and Lung Transplantation recommend assessing frailty (class IIb recommendation, level of evidence C). However, this recommendation is not based on prospective studies, and frailty scores have only been validated in patients age > 65 years. The aim of the FELICITAR registry (Frailty Evaluation After List Inclusion, Characteristics and Influence on Transplantation and Results) is to assess the impact of frailty on prognosis before and after heart transplantation. A series of 100 patients from 3 Spanish centers will be included as soon as they are added to the national heart transplantation waiting list. Frailty will be evaluated again every 3 months until heart transplantation and at 3, 6, and 12 months thereafter. Depression, cognitive assessment, and quality of life also will be analyzed. The 2 primary endpoints are all-cause mortality and prevalence of frailty assessed using the Fried frailty index. Results from this study may show that frailty is frequent in patients with advanced heart failure listed for heart transplantation and is associated with a poor prognosis both before and after surgery. The findings may contribute to a better understanding of the characteristics of the optimal candidate for heart transplantation.

AB - Jiao-Tai-Wan (JTW) is a well-known traditional Chinese medicine prescription composed of Rhizoma Coptidis (RC) and Cortex Cinnamon (10:1, g/g). It has been used to treat insomnia in China for centuries. This study investigates the excretion properties of coptis alkaloids from RC and JTW in normal and insomniac rats, and it examines the compatibility mechanism for this prescription. A new liquid chromatography-tandem mass spectrometry method was developed for the simultaneous determination of six alkaloids - berberine, epiberberine, coptisine, jatrorrhizine, palmatine and magnoflorine - in rat urine and feces. The normal and model rats were orally treated with RC and JTW powder at a dosage containing 3.0 g kg-1 day-1 RC once per day for 7 days. Briefly, the results showed that the cumulative amounts of urinary and fecal excretion of the six alkaloids were significantly different in the pathological condition, as well as in compatibility. In normal rats, the urinary and fecal excretion of coptis alkaloids, especially berberine, coptisine and palmatine, increased significantly in the JTW group compared with the RC group, while the urinary and fecal excretion of six alkaloids decreased in insomniac rats. These data suggested that pathological conditions might have a notable influence on the excretion of alkaloids in rats, and demonstrated that the compatibility could promote better therapeutic effects through the accumulation of alkaloids in the body. These results might explain the compatibility of JTW.

AB - N-methyl-D-aspartate receptors (NMDARs) are ion channels comprising tetrameric assemblies of GluN1 and GluN2 receptor subunits that mediate excitatory neurotransmission in the central nervous system. Of the four different GluN2 subunits, the GluN2D subunit-containing NMDARs have been suggested as a target for antiparkinsonian therapy because of their expression pattern in some of the basal ganglia nuclei that show abnormal firing patterns in the parkinsonian state, specifically the subthalamic nucleus (STN). In this study, we demonstrate that blockade of NMDARs altered spike firing in the STN in a male nonhuman primate that had been rendered parkinsonian by treatment with the neurotoxin 1 methyl-4-phenyl-1,2,3,6-tetrahydropyridine. In accompanying experiments in male rodents, we found that GluN2D-NMDAR expression in the STN was reduced in acutely or chronically dopamine-depleted animals. Taken together, our data suggest that blockade of NMDARs in the STN may be a viable antiparkinsonian strategy, but that the ultimate success of this approach may be complicated by parkinsonism associated changes in NMDAR expression in the STN.

AB - BACKGROUND: The seroclearance of hepatitis B surface antigen (HBsAg) in patients with chronic hepatitis B (CHB) is considered to be associated with favourable clinical outcomes. AIMS: This meta-analysis was performed to establish the proportion of HBsAg loss rates among CHB patients who received combination treatment based on pegylated interferon (PegIFN). Four combination strategies have been studied with the aim of improving HBsAg loss: "de novo," "NA experienced," "switch-to" and "add-on." This meta-analysis was performed to determine which, if any, of these combination strategies was more effective. METHODS: Medline, Web of Science and Embase databases were searched from inception to December 2017. The proportion of patients who achieved HBsAg loss after combination therapy was pooled using a random-effects model. RESULTS: Twenty-four studies fulfilled the meta-analysis criteria. The overall pooled proportion suggested that the rate of HBsAg loss could be increased to 9% (95% CI: 7%-12%) based on the combination treatment in CHB patients. Compared with "de novo" strategy (8%, 95% CI: 6%-10%), the "nucleos(t)ide analogues-experienced" (11%, 95% CI: 8%-15%) was found to be more likely (P = 0.036) to achieve a response. Compared with the "add-on" strategy (8%, 95% CI: 5%-13%), the "switch to" (14%, 95% CI: 9%-20%) was found to be more likely (P = 0.012) to achieve HBsAg loss. CONCLUSION: The "nucleos(t)ide analogues-experienced" strategy was more effective than the "De novo" strategy in achieving HBsAg loss for CHB patients. Combination treatment using regimens based on Peg-IFN may be useful to help nucleos(t)ide analogues-treated patients, who have experienced at least 48 weeks of nucleot(s)ide analogue, achieve HBsAg seroclearance.

AB - This study updates the review published by Wang et al in 2014 (Sleep Breath 2014;18(2):235-242). The review focuses on the most recent literature on management of sleep bruxism (SB) with biofeedback. An electronic search was conducted in five databases searching for articles published later than the date of Wang et al's search, viz., October 2012. Six articles of 2320 identified citations involving 86 adult participants were included in the qualitative synthesis. Of them, 4 were randomised controlled trials (RCTs) and 2 were uncontrolled before-after studies. Different feedback modalities (electrical, auditory and vibratory stimulus) were investigated. The overall quality of the selected studies was assessed using the GRADE criteria. Due to heterogeneity between studies, the quantitative synthesis was performed out of three RCTs, of which two were retrieved from the previous review. The meta-analysis indicated a non-significant difference in electromyographic-measured SB episodes per hour after one night of contingent electrical stimulation (CES) compared with placebo control, yet a significant difference was shown after five nights of CES. The quality of evidence identified through GRADEpro was from low to moderate, due to imprecision and inconsistency between studies. Qualitative synthesis did not present a reliable reduction in clinical pain levels; however, no substantial sleep disturbances were indicated following the intervention. In conclusion, one of the biofeedback modalities, CES, is effective in reducing SB-related motor activities after a short-term treatment period. However, evidence of long-term effects is lacking. Further longitudinal studies with larger samples are necessary to acknowledge the clinical application of biofeedback. PMID- 29577363 TI - Relative efficiency of unequal versus equal cluster sizes in cluster randomized trials using generalized estimating equation models. AB - There is growing interest in conducting cluster randomized trials (CRTs). For simplicity in sample size calculation, the cluster sizes are assumed to be identical across all clusters. However, equal cluster sizes are not guaranteed in practice. Therefore, the relative efficiency (RE) of unequal versus equal cluster sizes has been investigated when testing the treatment effect. One of the most important approaches to analyze a set of correlated data is the generalized estimating equation (GEE) proposed by Liang and Zeger, in which the "working correlation structure" is introduced and the association pattern depends on a vector of association parameters denoted by rho. In this paper, we utilize GEE models to test the treatment effect in a two-group comparison for continuous, binary, or count data in CRTs. The variances of the estimator of the treatment effect are derived for the different types of outcome. RE is defined as the ratio of variance of the estimator of the treatment effect for equal to unequal cluster sizes. We discuss a commonly used structure in CRTs-exchangeable, and derive the simpler formula of RE with continuous, binary, and count outcomes. Finally, REs are investigated for several scenarios of cluster size distributions through simulation studies. We propose an adjusted sample size due to efficiency loss. Additionally, we also propose an optimal sample size estimation based on the GEE models under a fixed budget for known and unknown association parameter (rho) in the working correlation structure within the cluster. PMID- 29577364 TI - Screening for therapeutic trials and treatment indication in clinical practice: MACK-3, a new blood test for the diagnosis of fibrotic NASH. AB - BACKGROUND: The composite histological endpoint comprising nonalcoholic steatohepatitis (NASH) and NAFLD activity score >=4 and advanced fibrosis (F >= 2) ("fibrotic NASH") is becoming an important diagnostic target in NAFLD: it is currently used to select patients for inclusion in phase III therapeutic trials and will ultimately be used to indicate treatment in clinical practice once the new drugs are approved. AIM: To develop a new blood test specifically dedicated for this new diagnostic target of interest. METHODS: Eight Hundred and forty-six biopsy-proven NAFLD patients from three centres (Angers, Nice, Antwerp) were randomised into derivation and validation sets. RESULTS: The blood fibrosis tests BARD, NFS and FIB4 had poor accuracy for fibrotic NASH with respective AUROC: 0.566 +/- 0.023, 0.654 +/- 0.023, 0.732 +/- 0.021. In the derivation set, fibrotic NASH was independently predicted by AST, HOMA and CK18; all three were combined in the new blood test MACK-3 (hoMa, Ast, CK18) for which 90% sensitivity and 95% specificity cut-offs were calculated. In the validation set, MACK-3 had a significantly higher AUROC (0.847 +/- 0.030, P <= 0.002) than blood fibrosis tests. Using liver biopsy in the grey zone between the two cut-offs (36.0% of the patients), MACK-3 provided excellent accuracy for the diagnosis of fibrotic NASH with 93.3% well-classified patients, sensitivity: 90.0%, specificity: 94.2%, positive predictive value: 81.8% and negative predictive value: 97.0%. CONCLUSION: The new blood test MACK-3 accurately diagnoses fibrotic NASH. This new test will facilitate patient screening and inclusion in NAFLD therapeutic trials and will enable the identification of patients who will benefit from the treatments once approved. PMID- 29577365 TI - Oleuropein, a component of extra virgin olive oil, lowers postprandial glycaemia in healthy subjects. AB - AIMS: Extra virgin olive oil lowers postprandial glycaemia. We investigated if oleuropein, a component of extra virgin olive oil, exerts a similar effect on postprandial glycaemia and the underlying mechanism. METHODS: Twenty healthy subjects were randomly allocated in a cross-over design to 20 mg oleuropein or placebo immediately before lunch. Postprandial glycaemia along with blood insulin, dipeptidyl-peptidase-4 (DPP-4) and glucagon-like peptide-1 and oxidative stress, which included soluble NADPH oxidase-derived peptide activity (sNox2-dp), 8-iso-prostaglandin-2alpha and platelet p47phox phosphorylation, were analysed before and 2 h after meal. RESULTS: After 2 h, subjects who assumed oleuropein had significantly lower blood glucose, DPP-4 activity and higher insulin and glucagon-like peptide-1 compared to placebo. Furthermore, sNox2-dp, 8-iso PGF2alpha and platelet p47phox phosphorylation were significantly lower in oleuropein- compared to placebo-treated subjects. DPP-4 significantly correlated with sNox2-dp [Spearman's rho (Rs) = 0.615; P < 0.001], p47phox phosphorylation (Rs = 0.435; P < 0.05) and 8-iso- prostaglandin-2alpha (Rs = 0.33; P < 0.05). In vitro study demonstrated that hydroxytyrosol, a metabolite of oleuropein, significantly reduced p47phox phosphorylation and isoprostane formation. CONCLUSIONS: These findings indicate that oleuropein improves postprandial glycaemic profile via hampering Nox2-derived oxidative stress. PMID- 29577366 TI - Suicide Ideation in Adolescents Following Inpatient Hospitalization: Examination of Intensity and Lability Over 6 Months. AB - Understanding suicide ideation (SI) in adolescents, especially during the high risk time following hospitalization for a suicidal event, is a crucial component of improving risk assessment. Most studies rely on single assessments of SI, despite the potential for SI to vary considerably over time. This study examined how indices of SI intensity (mean values) and lability (mean squared successive difference values) over a 6-month period predict suicide attempts (SAs) and self harm, as well as how they relate to psychosocial risk factors and affective functioning, in a sample of 103 adolescents hospitalized for a SA or significant SI. Across the sample, SI intensity, but not lability, was associated with SAs and nonsuicidal self-injury at 6-month follow-up. SI intensity performed similarly to single time point SI assessments, and its relations were not moderated by SI lability. SI intensity was also associated with borderline personality disorder criteria and a history of sexual abuse. In contrast, SI lability was associated with greater negative affect intensity and lability. These findings suggest that intensity of SI may confer more risk posthospitalization, and provide support for using these statistical methods to capture two distinct parameters of SI. PMID- 29577367 TI - Bioluminescence-driven optogenetic activation of transplanted neural precursor cells improves motor deficits in a Parkinson's disease mouse model. AB - The need to develop efficient therapies for neurodegenerative diseases is urgent, especially given the increasing percentages of the population living longer, with increasing chances of being afflicted with conditions like Parkinson's disease (PD). A promising curative approach toward PD and other neurodegenerative diseases is the transplantation of stem cells to halt and potentially reverse neuronal degeneration. However, stem cell therapy does not consistently lead to improvement for patients. Using remote stimulation to optogenetically activate transplanted cells, we attempted to improve behavioral outcomes of stem cell transplantation. We generated a neuronal precursor cell line expressing luminopsin 3 (LMO3), a luciferase-channelrhodopsin fusion protein, which responds to the luciferase substrate coelenterazine (CTZ) with emission of blue light that in turn activates the opsin. Neuronal precursor cells were injected bilaterally into the striatum of homozygous aphakia mice, which carry a spontaneous mutation leading to lack of dopaminergic neurons and symptoms of PD. Following transplantation, the cells were stimulated over a period of 10 days by intraventricular injections of CTZ. Mice receiving CTZ demonstrated significantly improved motor skills in a rotarod test compared to mice receiving vehicle. Thus, bioluminescent optogenetic stimulation of transplanted neuronal precursor cells shows promising effects in improving locomotor behavior in the aphakia PD mouse model and encourages further studies to elucidate the mechanisms and long-term outcomes of these beneficial effects. PMID- 29577368 TI - Higher expression of human telomerase reverse transcriptase in productively infected CD4 cells possibly indicates a mechanism for persistence of the virus in HIV infection. AB - Mechanisms involved in survival of productively-infected memory CD4+cells after initial antigenic stimulation and their subsequent reversion to the resting state are critical for the development of a predominant replication-competent HIV reservoir. These mechanisms may also counter their elimination after HIV reactivation through latency-reversing agents (LRA). Thus, their evaluation is critical when using an appropriate HIV latency model that recapitulates the predominant replication-competent HIV reservoir to develop strategies for HIV eradication. The model for evaluating the possible survival mechanisms after T cell receptor (TCR) stimulation was developed by infecting memory CD4+cells with an HIV-1C primary isolate and cytokine secretion and gene expression patterns determined. Infected cells showed compromised functionality as evident from 6.8 fold lower secretion of IL-2 than from uninfected control cells. After TCR stimulation, the infected cells showed significantly higher fold increases in CD27 and CCR5 and smaller increases in CD5 mRNA over baseline values. Because CD27 expression may influence telomerase activity through AKT phosphorylation, CD27, human telomerase reverse transcriptase (hTERT) and pAKT expression in productively-infected cells from HIV-infected patients was evaluated by flow cytometry. HIV harbored in memory CD4+ cells was reactivated by HIV-1 envelope peptides, which have been shown to act as effective LRA. P24+CD4+cell showed significantly higher expression of CD27, hTERT and pAKT than P24-CD4+cells. These findings indicate compromised functionality of HIV-infected cells after TCR stimulation, which may interfere with their elimination by the immune system. They also indicate that pAKT and hTERT induction are possible survival mechanisms of productively-infected CD4+cells. PMID- 29577369 TI - AldB controls persister formation in Escherichia coli depending on environmental stress. AB - Persisters are multidrug-tolerant cells that are present within antibiotic sensitive populations. Persister formation is not induced by genetic mutations, but rather by changes in the degree of expression of some genes. High redundancy has been observed among the pathways that have been hypothesized to respond to specific stresses. In this study, we conducted RNA sequencing of Escherichia coli persisters under various stress conditions to identify common mechanisms. We induced stresses such as glucose or amino acid exhaustion, acid stress and anaerobic conditions, all of which are encountered during bacterial pathogenesis. We found that most genes are differentially expressed depending on the specific stress condition; however, some genes were commonly expressed in persisters in most stress conditions. Commonly expressed genes are expected to be promising therapeutic targets for combating persistent infections. We found that knockdown of aldehyde dehydrogenase (aldB), which was expressed in every condition except for acid stress, decreased persisters in the non-stressed condition. However, the same strain unexpectedly showed an increased number of persisters in the amino acid-limited condition. Because the increase in persister number is glycolytic metabolite-dependent, metabolic flow may play a crucial role in aldB-mediated persister formation. These data suggest that environmental stresses alter persister mechanisms. Identification of environmental influences on persister formation during pathogenesis is therefore necessary to enabling persister eradication. PMID- 29577370 TI - Dynamic analysis of expression of chemokine and cytokine gene responses to H5N1 and H9N2 avian influenza viruses in DF-1 cells. AB - H5N1 and H9N2 are the most important causes of avian influenza in China. Chemokines and cytokines play important roles in inflammatory response that clearly differ between H5N1 and H9N2 infection. To investigate whether chemokines and cytokines are differentially regulated following H5N1 and H9N2 AIVs infection, dynamic expression of chemokines and cytokines, including IL8L1, IL8L2, CX3CL1, CCL5, CCL20, K203, SCYA4, XLC1, CCLi10, CCL19, IFN-alpha, IFN beta, IL-1beta, IL-6 and TNF-alpha, were analyzed by real-time quantitative RT PCR in DF-1 cells. It was found that IL8L1, IL8L2, CX3CL1, CCL5, CCL20, K203, SCYA4, IFN-alpha, IFN-beta, IL-1beta, IL-6 and TNF-alpha increased significantly after induction of H5N1 or H9N2 AIV infection, whereas no expression of XCL1, CCLi10 or CCL19 was detected. H9N2 AIV infection was associated with much stronger chemokine responses than infection with H5N1, whereas the cytokines showed opposite results. It was found that K203 is a constant chemotactic factor independent of subtype of AIVs and infectious dose, CCL20 and IL-1beta are constant regardless of the infectious dose but depend on the subtype of AIV, chemotactic factors IL8L1, IL8L2 and CCL5 are dependent both on subtype of AIVs and infectious dose, and K203, CX3CL1, SCYA4, CCL20, IFN-alpha, IL-1beta and TNF alpha are specific to responses to H5N1 AIV infection whereas K203, CCL20, IFN beta, IL-1beta and IL-6 are specific to H9N2 infection. These results provide basic data for explaining differences in inflammation and phenotypes of histopathological changes caused by H5N1 and H9N2 and add new information on the roles of chemokines and cytokines in virulence of AIVs. PMID- 29577371 TI - Role of T-bet, the master regulator of Th1 cells, in the cytotoxicity of murine CD4+ T cells. AB - Although CD4+ T cells are generally regarded as helper T cells, some activated CD4+ T cells have cytotoxic properties. Given that CD4+ cytotoxic T lymphocytes (CTLs) often secrete IFN-gamma, CTL activity among CD4+ T cells may be attributable to Th1 cells, where a T-box family molecule, T-bet serves as the "master regulator". However, although the essential contribution of T-bet to expression of IFN-gamma has been well-documented, it remains unclear whether T bet is involved in CD4+ T cell-mediated cytotoxicity. In this study, to investigate the ability of T-bet to confer cytolytic activity on CD4+ T cells, the T-bet gene (Tbx21) was introduced into non-cytocidal CD4+ T cell lines and their cytolytic function analyzed. Up-regulation of FasL (CD178), which provided the transfectant with cytotoxicity, was observed in Tbx21transfected CD4+ T cells but not in untransfected parental cells. In one cell line, T-bet transduction also induced perforin gene (Prf1) expression and Tbx21 transfectants efficiently killed Fas- target cells. Although T-bet was found to repress up-regulation of CD40L (CD154), which controls FasL-mediated cytolysis, the extent of CD40L up regulation on in vitro-differentiated Th1 cells was similar to that on Th2 cells, suggesting the existence of a compensatory mechanism. These results collectively indicate that T-bet may be involved in the expression of genes, such as FasL and Prf1, which confer cytotoxicity on Th1 cells. PMID- 29577372 TI - Effect of tadalafil on chronic pelvic pain and prostatic inflammation in a rat model of experimental autoimmune prostatitis. AB - BACKGROUND: Experimental autoimmune prostatitis (EAP) shares important clinical features with clinical chronic prostatitis/chronic pelvic pain. We investigated the effect of tadalafil on pelvic pain and prostatic inflammation in a rat EAP model. METHODS: EAP was induced in rats by intradermal injection of rat prostate antigen and complete Freund's adjuvant on days 0 and 28. Rats were treated with tadalafil (2 mg/kg, p.o.; EAP-tadalafil) or vehicle (EAP-vehicle) once daily from day 0, while sham-operated animals were treated with vehicle only (Sham). Tactile allodynia was measured on days 28, 35, and 42 by applying von Frey filaments to the lower abdomen as an index of pelvic pain. On day 42, the plasma immunoglobulin G (IgG) concentration and the testosterone/estradiol ratio were measured and histopathological analysis of the prostate was performed. RESULTS: Tactile allodynia in the pelvic region was observed on days 28, 35, and 42 after EAP induction. The tactile allodynia observed on day 42 was significantly reduced by repeated treatment with tadalafil. Plasma IgG concentrations increased after EAP induction but the increase was not changed by tadalafil treatment. Prostate tissues were characterized by epithelial necrosis, infiltration of neutrophils and/or lymphocytes to acini and stroma, and fibrosis, in addition to a high stroma-to-epithelium ratio. Tadalafil treatment significantly suppressed the severity of the lesions. CONCLUSIONS: EAP rats developed pelvic pain, prostatic inflammation and increased plasma IgG concentrations. Tadalafil inhibited the chronic pelvic pain and prostatic inflammation, suggesting that its anti inflammatory action may contribute to its blocking of pain development in the EAP model.

PMID- 29577374 TI - Comparison of behavioral, neuroprotective, and proinflammatory cytokine modulating effects exercised by (+)-cis-EC and (-)-cis-EC stereoisomers in a PTZ induced kindling test in mice. AB - Epoxy-carvone (EC) has chiral centers that allow generation of stereoisomers, including (+)-cis-EC and (-)-cis-EC, whose effects in the kindling tests have never been studied. Accordingly, this study aims to comparatively investigate the effect of stereoisomers (+)-cis-epoxy-carvone and (-)-cis-epoxy-carvone on behavioral changes measured in scores, in the levels of cytokines (IL-1beta, IL 6, and TNFalpha) and neuronal protection in the face of continuous treatment with pentylenetetrazol. Swiss mice were divided into five groups (n = 10), receiving vehicle, (+) - cis-EC, (-) - cis-EC (both at the dose of 30 mg/kg), and diazepam (4 mg/kg). Thirty minutes after the respective treatment was administered to the animals one subconvulsive dose of PTZ (35 mg/kg). Seven subconvulsives treatments were made on alternate days, in which each treatment several parameters were recorded. In the eighth treatment, the animals receiving the highest dose of PTZ (75 mg/kg) and were sacrificed for quantification of cytokines and histopathologic analysis. All drugs were administered by intraperitoneal route. In the kindling test, (+)-cis-EC and (-)-cis-EC reduced the average scores. The stereoisomer (+)-cis-EC decreased levels of proinflammatory cytokines IL-1beta, IL-6, and TNFalpha, whereas comparatively (-)-cis-EC did not reduce IL-1beta levels. Histopathological analysis of the mice hippocampi undergoing this methodology showed neural protection for treated with (+)-cis-EC. The results suggest that the anticonvulsant effect of (+)-cis-EC possibly takes place due to reduction of proinflammatory cytokines involved in the epileptogenic process, besides neuronal protection, yet further investigation of the mechanisms involved is required. PMID- 29577375 TI - Ca2+/calmodulin-dependent protein kinase II and Dimethyl Sulfoxide affect the sealing frequencies of transected hippocampal neurons. AB - Traumatic injury often results in axonal severance, initiating obligatory Wallerian degeneration of distal segments, whereas proximal segments often survive. Calcium ion (Ca2+ ) influx at severed proximal axonal ends activates pathways that can induce apoptosis. However, this same Ca2+ -influx also activates multiple parallel pathways that seal the plasmalemma by inducing accumulation and fusion of vesicles at the lesion site that reduce Ca2+ -influx and enhance survival. We examined whether various inhibitors of Ca2+ /calmodulin dependent protein kinases (CaMKs), and/or dimethyl sulfoxide (DMSO), a common solvent for biologically active substances, affected the ability of a hippocampal derived neuronal cell line (B104 cells) to seal membrane damage following axotomy. Axolemmal sealing frequencies were assessed at different transection distances from the axon hillock and at various times after Ca2+ -influx (PC times) by observing whether transected cells took-up fluorescent dyes. Inhibition of CaMKII by tatCN21 and KN-93, but not inhibition of CaMKI and CaMKIV by STO 609, affected axonal sealing frequencies. That is, CaMKII is a component of previously reported parallel pathways that induce membrane sealing, whereas CaMKI and CaMKIV are not involved. The effects of these CaMKII inhibitors on plasmalemmal sealing depended on their mechanism of inhibition, transection distance, and PC time. DMSO at low concentrations (90 uM-28 mM or 0.00064%-0.2% v/v) significantly increased membrane-sealing frequencies at most PC times and transection distances, possibly by permeabilizing the plasmalemma to Ca2+ . Inhibition of CaMKII, DMSO, PC time, and the transection distance significantly affect plasmalemmal sealing that is critical to somal survival in traumatic lesions. PMID- 29577376 TI - Dynamic prediction of cumulative incidence functions by direct binomial regression. AB - In recent years there have been a series of advances in the field of dynamic prediction. Among those is the development of methods for dynamic prediction of the cumulative incidence function in a competing risk setting. These models enable the predictions to be updated as time progresses and more information becomes available, for example when a patient comes back for a follow-up visit after completing a year of treatment, the risk of death, and adverse events may have changed since treatment initiation. One approach to model the cumulative incidence function in competing risks is by direct binomial regression, where right censoring of the event times is handled by inverse probability of censoring weights. We extend the approach by combining it with landmarking to enable dynamic prediction of the cumulative incidence function. The proposed models are very flexible, as they allow the covariates to have complex time-varying effects, and we illustrate how to investigate possible time-varying structures using Wald tests. The models are fitted using generalized estimating equations. The method is applied to bone marrow transplant data and the performance is investigated in a simulation study. PMID- 29577377 TI - Improved calculation of the equilibrium magnetization of arterial blood in arterial spin labeling. AB - PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling. METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this ratio. The nominator is redefined as the magnetization of perfused tissue, and the denominator is redefined as a weighted sum of tissue-specific partition coefficients. Perfusion data were acquired with a pseudo-continuous arterial spin labeling sequence, and partial-volume data were acquired using a rapid saturation recovery sequence with the same readout module. Results from 7 healthy volunteers were analyzed and compared with the conventional method. RESULTS: The proposed method produced improved M0a homogeneity throughout the brain in all subjects. The mean gray matter perfusion was significantly higher with the proposed method compared with the conventional method: 61.2 versus 56.3 mL/100 g/minute (+8.7%). Although to a lesser degree, the corresponding white matter values were also significantly different: 20.8 versus 22.0 mL/100 g/minute (-5.4%). The spatial and quantitative differences between the 2 methods were similar in all subjects. CONCLUSION: Compared with the conventional approach, the proposed method produced more homogenous M0a maps, corresponding to a more accurate calibration. The proposed method also yielded significantly different perfusion values across the whole brain, and performed consistently in all subjects. The new M0a method improves quantitative perfusion estimation with arterial spin labeling, and can therefore be of considerable value in perfusion imaging applications. PMID- 29577378 TI - Relationship between alcohol consumption and periodontal tissue condition in community-dwelling elderly Japanese. AB - OBJECTIVES: To examine the associations among alcohol consumption level, dietary intake and other lifestyle factors, and periodontal condition, in community dwelling elderly Japanese of a specific age. BACKGROUND: The relationship between alcohol consumption level and periodontitis is a controversial issue. METHODS: Participants were 438 dentate elders aged 73 years from a larger cohort survey of elders in Niigata City, Japan. Data collected from oral examination of each participant, including number of the existing teeth, mean probing pocket depth and mean clinical attachment level (CAL) were used for the analyses. A semiquantitative food frequency questionnaire and a lifestyle habit questionnaire were used to assess food and alcohol consumption, smoking experience, frequency of tooth brushing, interdental brush use, and visits to a dental clinic during the previous year. Blood glucose control was assessed by the glycated haemoglobin (HbA1c) level. Body mass index was calculated from height and weight measurements. The relationships between each variable and the individual mean CAL were analysed by univariate and multivariate analyses. RESULTS: According to logistic regression analysis, the mean CAL was significantly associated with the number of existing teeth (odds ratio [OR] = 0.90; P < .001), being a heavy drinker (OR = 2.44; P < .05), and smoking experience (OR = 2.37; P < .01). CONCLUSION: This study showed that increased mean CAL was significantly associated with heavy drinking in community-dwelling elderly Japanese (aged 73 years) compared with non-drinking. Our results provide new evidence that high alcohol consumption is associated with an increased risk of periodontal disease and its progression.

PMID- 29577380 TI - The effect of medical and operative birth interventions on child health outcomes in the first 28 days and up to 5 years of age: A linked data population-based cohort study. AB - BACKGROUND: Spontaneous vaginal birth rates are decreasing worldwide, while cesarean delivery, instrumental births, and medical birth interventions are increasing. Emerging evidence suggests that birth interventions may have an effect on children's health. Therefore, the aim of our study was to examine the association between operative and medical birth interventions on the child's health during the first 28 days and up to 5 years of age. METHODS: In New South Wales (Australia), population-linked data sets were analyzed, including data on maternal characteristics, child characteristics, mode of birth, interventions during labor and birth, and adverse health outcomes of the children (ie, jaundice, feeding problems, hypothermia, asthma, respiratory infections, gastrointestinal disorders, other infections, metabolic disorder, and eczema) registered with the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification codes. Logistic regression analyses were performed for each adverse health outcome. RESULTS: Our analyses included 491 590 women and their children; of those 38% experienced a spontaneous vaginal birth. Infants who experienced an instrumental birth after induction or augmentation had the highest risk of jaundice, adjusted odds ratio (aOR) 2.75 (95% confidence interval [CI] 2.61-2.91) compared with spontaneous vaginal birth. Children born by cesarean delivery were particularly at statistically significantly increased risk for infections, eczema, and metabolic disorder, compared with spontaneous vaginal birth. Children born by emergency cesarean delivery showed the highest association for metabolic disorder, aOR 2.63 (95% CI 2.26-3.07). CONCLUSION: Children born by spontaneous vaginal birth had fewer short- and longer-term health problems, compared with those born after birth interventions. PMID- 29577381 TI - Remote Mentoring of Point-of-Care Ultrasound Skills to Inexperienced Operators Using Multiple Telemedicine Platforms: Is a Cell Phone Good Enough? AB - OBJECTIVES: Telemedicine technology contributes to the teaching of point-of-care ultrasound (US); however, expensive equipment can limit its deployment in resource-challenged settings. We assessed 3 low-cost telemedicine solutions capable of supporting remote US training to determine feasibility, acceptability, and effectiveness. We also explored the value of instructional videos immediately before telementoring. METHODS: Thirty-six participants were randomly assigned to receive US mentoring in 1 of 3 telemedicine conditions: multiple fixed cameras, a smartphone, and traditional audio with a live US stream. Participants were then asked to perform a standardized US examination of the right upper quadrant under remote guidance. We measured observer's global ratings of performance along with the mentor's and student's rating of effort and satisfaction to determine which of the 3 approaches was most feasible, acceptable, and effective. During the second phase, students were randomized to watch an instructional video or not before receiving remote coaching on how to complete a subxiphoid cardiac examination. Effort, satisfaction, and performance from the independent observer's and student's perspective were surveyed. RESULTS: There was no significant difference between the different telemedicine setups from the observer's perspective; however, the mentor rated the smartphone significantly worse (P = .028-.04) than other technologies. Platforms were rated equivalent from the student's perspective. No benefit was detected for watching an instructional video before the mentored task. CONCLUSIONS: Remote US skills can be taught equally effectively by using a variety of telemedicine technologies. Smartphones represent a viable option for US training in resource-challenged settings. PMID- 29577382 TI - MRI detection of bacterial brain abscesses and monitoring of antibiotic treatment using bacCEST. AB - PURPOSE: To develop a new MRI method to detect and characterize brain abscesses using the CEST contrast inherently carried by bacterial cells, namely bacCEST. METHODS: Bacteria S. aureus (ATCC #49775) and F98 and 9L glioma cells were injected stereotactically in the brains of F344 rats to form abscesses and tumors. The CEST signals of brain abscesses (n = 4) and tumors (n = 7) were acquired using 2 B1 values (i.e., 1 and 3 uT) and compared. The bacCEST signal of the brain abscesses in the rats (n = 3) receiving ampicillin (intraperitoneal injection 40 mg/kg twice daily) was acquired before, 4 and 10 days after the treatment. RESULTS: The bacCEST signal of S. aureus was characterized in vitro as a strong and broad signal in the range of 1 to 4 ppm, with the maximum contrast occurring at 2.6 ppm. The CEST signal in S. aureus-induced brain abscesses was significantly higher than that of contralateral parenchyma (p = .003). Moreover, thanks to their different B1 independence, brain abscesses and tumors could be effectively differentiated (p = .005) using DeltaCEST(2.6 ppm, 3 uT-1 uT), defined by the difference between the CEST signal (offset = 2.6 ppm) acquired using B1 = 3 uT and that of 1 uT. In treated rats, bacCEST MRI could detect the response of bacteria as early as 4 days after the antibiotic treatment (p = .035). CONCLUSION: BacCEST MRI provides a new imaging method to detect, discriminate, and monitor bacterial infection in deep-seated organs. Because no contrast agent is needed, such an approach has a great translational potential for detecting and monitoring bacterial infection in deep-seated organs. PMID- 29577405 TI - Smooth individual level covariates adjustment in disease mapping. AB - Spatial models for disease mapping should ideally account for covariates measured both at individual and area levels. The newly available "indiCAR" model fits the popular conditional autoregresssive (CAR) model by accommodating both individual and group level covariates while adjusting for spatial correlation in the disease rates. This algorithm has been shown to be effective but assumes log-linear associations between individual level covariates and outcome. In many studies, the relationship between individual level covariates and the outcome may be non log-linear, and methods to track such nonlinearity between individual level covariate and outcome in spatial regression modeling are not well developed. In this paper, we propose a new algorithm, smooth-indiCAR, to fit an extension to the popular conditional autoregresssive model that can accommodate both linear and nonlinear individual level covariate effects while adjusting for group level covariates and spatial correlation in the disease rates. In this formulation, the effect of a continuous individual level covariate is accommodated via penalized splines. We describe a two-step estimation procedure to obtain reliable estimates of individual and group level covariate effects where both individual and group level covariate effects are estimated separately. This distributed computing framework enhances its application in the Big Data domain with a large number of individual/group level covariates. We evaluate the performance of smooth-indiCAR through simulation. Our results indicate that the smooth-indiCAR method provides reliable estimates of all regression and random effect parameters. We illustrate our proposed methodology with an analysis of data on neutropenia admissions in New South Wales (NSW), Australia. PMID- 29577404 TI - High-throughput measurement of recombination rates and genetic interference in Saccharomyces cerevisiae. AB - Allelic recombination owing to meiotic crossovers is a major driver of genome evolution, as well as a key player for the selection of high-performing genotypes in economically important species. Therefore, we developed a high-throughput and low-cost method to measure recombination rates and crossover patterning (including interference) in large populations of the budding yeast Saccharomyces cerevisiae. Recombination and interference were analysed by flow cytometry, which allows time-consuming steps such as tetrad microdissection or spore growth to be avoided. Moreover, our method can also be used to compare recombination in wild type vs. mutant individuals or in different environmental conditions, even if the changes in recombination rates are small. Furthermore, meiotic mutants often present recombination and/or pairing defects affecting spore viability but our method does not involve growth steps and thus avoids filtering out non-viable spores. PMID- 29577407 TI - Echocardiographic and clinical markers of left ventricular ejection fraction and moderate or greater systolic dysfunction in left ventricular noncompaction cardiomyopathy. AB - BACKGROUND: Left ventricular noncompaction (LVNC) is associated with progressive LV systolic dysfunction and dilated cardiomyopathy. We aimed to investigate the echocardiographic and clinical characteristics associated with LV ejection fraction (LVEF) and moderate or greater systolic dysfunction in patients with LVNC. METHODS: Our institutional echocardiography database was retrospectively reviewed between 2008 and 2014, and 62 patients with LVNC were identified. Forty three (69%) had moderate or greater LV systolic dysfunction (LVEF <= 40%) and were compared with 19 (31%) patients with preserved or mildly reduced LVEF (>40%). Linear regression analyses were utilized to identify markers associated with LVEF. RESULTS: The mean age was 63 +/- 17 years and noncompacted-to compacted ratio was 2.3 +/- 0.5, and was larger in patients with LVEF <= 40% (2.4 vs 2.1; P = .02). Patients with LVEF <= 40% were older, had more congestive heart failure, significant QRS interval prolongation, and greater LV remodeling and worse mean global longitudinal strain (GLS). Multivariate regression analysis revealed increased age (standardized regression coefficient (beta) = -0.17; P = .04) and QRS duration (beta = -0.13; P = .08), congestive heart failure (beta = 0.18; P = .04), and worsened GLS (beta = -0.40; P = .001) were independently associated with decreased LVEF in the cohort (overall model fit R2 = 0.71; P < .0001). Increased age (beta = -0.49; P = .01) and QRS duration (beta = -0.50; P = .002), and worsened GLS (beta = -0.33; P = .04), were also associated with a lower LVEF in patients with LVEF > 40%. CONCLUSIONS: The independent markers associated with LVEF and moderate or greater LV systolic dysfunction in patients with LVNC, in particular GLS and QRS duration, may detect high-risk candidates for more aggressive clinical surveillance and medical therapy. PMID- 29577406 TI - Quantifying myofiber integrity using diffusion MRI and random permeable barrier modeling in skeletal muscle growth and Duchenne muscular dystrophy model in mice. AB - PURPOSE: To measure the microstructural changes during skeletal muscle growth and progressive pathologies using the random permeable model with diffusion MRI, and compare findings to conventional imaging modalities such as three-point Dixon and T2 imaging. METHODS: In vivo and ex vivo DTI experiments with multiple diffusion times (20-700 ms) were completed on wild-type (n = 22) and muscle-dystrophic mdx mice (n = 8) at various developmental time points. The DTI data were analyzed with the random permeable model framework that provides estimates of the unrestricted diffusion coefficient (D0 ), membrane surface-to-volume ratio (S/V), and membrane permeability (kappa). In addition, the MRI experiments included conventional measures, such as tissue fat fractions and T2 relaxation. RESULTS: During normal muscle growth between week 4 and week 13, the in vivo S/V, fractional anisotropy, and fat fraction correlated positively with age (rho = 0.638, 0.664, and 0.686, respectively), whereas T2 correlated negatively (rho = 0.847). In mdx mice, all DTI random permeable model parameters and fat fraction had significant positive correlation with age, whereas fractional anisotropy and T2 did not have significant correlation with age. Histological measurements of the perimeter-to-area ratio served as a proxy for the model-derived S/V in the cylindrical myofiber geometry, and had a significant correlation with the ex vivo S/V (r = 0.71) as well as the in vivo S/V (r = 0.56). CONCLUSION: The present study demonstrates that DTI at multiple diffusion times with the random permeable model analysis allows for noninvasively quantifying muscle fiber microstructural changes during both normal muscle growth and disease progression. Future studies can apply our technique to evaluate current and potential treatments to muscle myopathies. PMID- 29577408 TI - The role of intraoperative epicardial echocardiography in pediatric cardiac surgery. AB - AIM: Our aim was to evaluate the findings and the role of intraoperative epicardial echocardiography (IEE) in the management of pediatric cardiac surgery patients. METHODS: Patients evaluated with IEE between December 2015 and December 2017 were analyzed retrospectively. Demographic data, preoperative transthoracic echocardiography (TTE), and IEE reports were evaluated. RESULTS: A total of 410 patients evaluated by IEE were included in the study. Of these, 52% were women, and 48% were men. The median age was 8.5 months (range: 1 month-7 years), and median body weight was 7.1 kg (range: 3.3-61 kg). The most common diagnoses were tetralogy of Fallot (TOF; n = 148), ventricular septal defect (VSD; n = 117), atrial septal defect (ASD; n = 57), and complete atrioventricular septal defect (AVSD; n = 48). There were minor residual lesions not requiring reestablishment of cardiopulmonary bypass (CPB) in 16.6% (n = 68), while major residual lesions requiring return to CPB were determined in 5.1% (n = 21). Major residual lesions were detected in 7 patients with TOF (4 severe right ventricular outflow tract obstructions, 2 pulmonary artery stenosis, 1 residual VSD shunt), 6 patients with VSD (hemodynamically significant residual shunts), and 5 patients with complete AVSD (3 left atrioventricular valve regurgitations, 1 right atrioventricular valve regurgitation, 1 left ventricular outflow tract obstruction). Transient bradycardia was observed in 5 patients. CONCLUSION: Intraoperative epicardial echocardiography provides good guidance during congenital heart surgery. IEE helps to clarify the surgical planning and decreases morbidity and mortality due to unnecessary invasive procedures, especially for pathologies involving the pulmonary artery and its branches, as well as for apical ventricular septal defects. PMID- 29577409 TI - Effect of treatment of symptomatic convergence insufficiency on reading in children: a pilot study. AB - BACKGROUND: To evaluate the impact of treatment of symptomatic convergence insufficiency using office-based vergence/accommodative therapy on reading skills in children. METHODS: Children (n = 44) ages nine to 17 years with symptomatic convergence insufficiency were administered the following four reading tests: Wechsler Individual Achievement Test II; Test of Word Reading Efficiency; Test of Silent Word Reading Fluency; and the Gray Oral Reading Test, at baseline and eight weeks after completion of a 16-week program of office-based vergence/accommodative therapy. To determine whether significant change occurred with therapy, change in performance was compared to zero. Treatment response was determined using a composite score of symptoms and signs at the conclusion of treatment and at the 24-week outcome visit. Participants were classified as early responders, late responders, or non-responders based upon whether criteria for successful treatment were met at the completion of 16 weeks of treatment, at the 24-week outcome visit, or not met at either visit, respectively. RESULTS: After treatment for convergence insufficiency, statistically significant improvements were found for reading comprehension (mean = 4.2, p = 0.009) and the reading composite score (mean = 2.4, p = 0.016) as measured by the Wechsler Individual Achievement Test at the 24-week visit. These improvements were related to the clinical treatment outcome measures (p = 0.011) with the largest improvements occurring in those who were early responders to treatment. Reading speed (words per minute) increased significantly on the Gray Oral Reading Test (p < 0.0001). No significant improvements were observed for single word reading or reading fluency as measured by the Test of Word Reading Efficiency, the Test of Silent Word Reading Fluency or the Gray Oral Reading Test. CONCLUSION: Improvements in reading comprehension and reading composite were found after office-based vergence/accommodative therapy, with the greatest improvements in those who responded early to treatment. PMID- 29577410 TI - Adult care providers' perspectives on the transition to adult care for emerging adults with Type 1 diabetes: a cross-sectional survey. AB - AIMS: To assess adult diabetes care providers' current transition practices, knowledge about transition care, and perceived barriers to implementation of best practices in transition care for emerging adults with Type 1 diabetes mellitus. METHODS: We administered a 38-item web-based survey to adult diabetes care providers identified through the Quebec Endocrinologist Medical Association and Diabetes Quebec. RESULTS: Fifty-three physicians responded (35%). Fewer than half of all respondents (46%) were familiar with the American Diabetes Association's transition care position statement. Approximately one-third of respondents reported a gap of >6 months between paediatric and adult diabetes care. Most (83%) believed communication with the paediatric team was adequate; however, only 56% reported receiving a medical summary and 2% a psychosocial summary from the paediatric provider. Respondents believed that the paediatric team should improve emerging adults' preparation for transition care by developing their self management skills and improve teaching about the differences between paediatric and adult-oriented care. Only 31% had a system for identifying emerging adults lost to follow-up in adult care. Perceived barriers included difficulty accessing psychosocial services, emerging adults' lack of motivation, and inadequate transition preparation. Most (87%) were interested in having additional resources, including a self-care management tool and a registry to track those lost to follow-up. CONCLUSIONS: Our findings highlight the need to better engage adult care providers into transition care practices. Despite adult physicians' interest in transition care, implementation of transition care recommendations and resources in clinical care remains limited. Enhanced efforts are needed to improve access to mental health services within the adult healthcare setting. PMID- 29577411 TI - A pneumococcal conjugate vaccination programme reduced clinically suspected invasive disease in unvaccinated children. AB - AIM: The 10-valent pneumococcal conjugate vaccine was introduced to the Finnish national vaccination programme for children born since June 2010. We evaluated the changes in the rates of clinically suspected invasive pneumococcal disease (IPD) in unvaccinated children to estimate the indirect herd protection impact of the programme. METHODS: The target cohort for this ecological before and after comparison were unvaccinated children born from January 2008 to May 2010 and ineligible for the vaccination programme, who were followed up from 2011 to 2014. The reference cohort was age and season-matched children born in January 2003 to 2005 and followed up from 2006 to 2009. National data on hospital discharge codes compatible with IPD or unspecified sepsis were collected. RESULTS: We compared the follow-up periods of 2007-2009 in the reference cohort and 2012-2014 in the target cohort. The incidence of non-laboratory-confirmed IPD in unvaccinated children fell by 68%, from 47 to 15/100 000 person-years. When unspecified sepsis was added, the decrease was 39%, from 171 to 104/100 000 person-years. Laboratory confirmed IPD fell by 44%, from 15 to 8/100 000 person-years. CONCLUSION: The pneumococcal vaccination programme provided herd protection against clinically suspected IPD. The absolute reduction was almost 10-times higher than for just laboratory-confirmed disease. PMID- 29577413 TI - Extracellular vesicles as mediators of immunopathology in infectious diseases. AB - In the last decades, extracellular vesicles have emerged as important elements in cell-cell communication and as key players in disease pathogenesis via transmission of their cargo between different cells. Various works have described different subpopulations of these membrane structures, based on their cell of origin, biogenesis, size, biophysical properties and cargo. In addition to their pathophysiological role in the development and progression of different diseases including infectious diseases, neurodegenerative disorders and cancer, extracellular vesicles are now recognized for their potential as novel therapeutic targets and intelligent drug delivery system. Here, we have reviewed the most recent data on different subtypes of extracellular vesicles, focusing on microvesicles and exosomes and their subpopulations, their involvement in immune mediated pathogenesis of various infectious diseases and their role as potential therapeutic targets. PMID- 29577412 TI - Sulfated vizantin induces formation of macrophage extracellular traps. AB - Vizantin is an insoluble adjuvant that activates macrophages and lymphocytes. Recently, 2,2',3,3',4,4'-hexasulfated-vizantin (sulfated vizantin), which enables solubilization of vizantin, was developed by the present team. Sulfated vizantin was found to enhance bactericidal activity against multi-drug resistant Pseudomonas aeruginosa in RAW264.7 cells. In addition, spread of P. aeruginosa was inhibited in RAW264.7 cells treated with sulfated vizantin. When only sulfated vizantin and P. aeruginosa were incubated, sulfated vizantin did not affect growth of P. aeruginosa. Formation of DNA-based extracellular traps (ETs), a novel defense mechanism in several types of innate immune cells, helps to eliminate pathogens. In the present study, ET-forming macrophages constituted the majority of immune cells. Sulfated vizantin induced ET formation in RAW264.7 cells, whereas a Ca-chelating reagent, EDTA, and T-type calcium channel blocker, tetrandrine, inhibited ET formation and attenuated inhibition of spread of P. aeruginosa in sulfated vizantin-treated cells. Thus, sulfated vizantin induces ET formation in phagocytic cells in a Ca-dependent manner, thus preventing spread of P. aeruginosa. Hence, sulfated vizantin may be useful in the management of infectious diseases. PMID- 29577415 TI - The morphology of the reproductive system in the crab Percnon gibbesi (Decapoda: Brachyura: Grapsoidea) reveals a new combination of characters in Thoracotremata. AB - Recent studies revealed a high diversity of reproductive structures in heterotreme brachyurans, while those of Thoracotremata seem rather uniform. Yet, there still is a huge lack of data in this group as only few species have been studied with respect to their reproductive system. The phylogenetic position of Percnidae is ambiguous. Recent molecular studies place it within polyphyletic grapsoids. We herein study the reproductive morphology of Percnon gibbesi using histology, scanning electron microscopy, micro-computed tomography and 3D reconstructions to test whether this species shows the characteristic thoracotreme pattern. Our results reveal that the male copulatory system conforms to other thoracotremes. It is composed of two pairs of pleopods (gonopods) and likewise paired penes. The first gonopod is relatively long. It possesses a bent terminal process with a distal opening of the ejaculatory canal, a character also present in other grapsoids. The second gonopod is short and terminates in an apical girdle. The female reproductive system reveals a combination of characters, so far unknown for thoracotremes. The paired oviducts do not lead into the seminal receptacles, but run into separate cuticular ducts joined with the vaginae. Accessory sperm storage organs, the bursae, are also connected to the vaginae. Bursae have previously only been described in heterotreme crabs. The data presented in this study reveals a higher diversity of thoracotreme reproductive systems than anticipated. PMID- 29577414 TI - Molecular insight into targeting the NK cell immune response to cancer. AB - Natural Killer (NK) cells have long been considered an important part of the anti tumor immune response due to their potent cytolytic and cytokine-secreting abilities. To date, a clear demonstration of the role NK cells play in human cancer is lacking, and there are still very few examples of therapies that efficiently exploit or enhance the spontaneous ability of NK cells to destroy the autologous cancer cells. Given the paradigm shift toward cancer immunotherapy over the past decade, there is a renewed push to understand how NK cell homeostasis and function are regulated in order to therapeutically harness these cells to treat cancer. This review will highlight recent advancements in our understanding of how growth factors impact on NK cell development, differentiation, survival and function with an emphasis on how these pathways may influence NK cell activity in the tumor microenvironment and control of cancer metastasis. PMID- 29577416 TI - Retrospective study of paracetamol poisoning in children aged zero to six years found no cases of liver injury. AB - AIM: This study focused on children aged zero to six years with suspected single dose paracetamol poisoning, which has not been investigated in Denmark. We evaluated the incidence of liver injuries and the use of activated charcoal and N acetylcysteine treatment. METHODS: Our retrospective study was performed in three paediatric hospital centres from 2001 to 2012. Data on symptoms, time of ingestion, blood biochemistry, treatment and adverse reactions were collected. The results were evaluated against the Rumack-Matthew nomogram. RESULTS: We identified 221 children (58% male), with a mean age of 2.67 +/- 1.05 years. Activated charcoal treatment was given in 87% of cases, but only 15% of the children received treatment within one hour of the suspected paracetamol poisoning. Although 80% of the children received N-acetylcysteine treatment, only one case (0.5%) had a toxic plasma paracetamol level according to the treatment nomogram. Abdominal pain or vomiting was associated with higher paracetamol levels in plasma. None of the children developed liver injuries. CONCLUSION: We found a low incidence of significant poisoning and liberal use of N acetylcysteine and activated charcoal treatment in Danish children aged zero to six years with suspected paracetamol poisoning. Vomiting or abdominal pain was associated with elevated plasma paracetamol levels. No liver injuries were reported. PMID- 29577417 TI - Antibiotics in the first week of life were associated with atopic asthma at 12 years of age. AB - AIM: This study explored the prevalence of atopic and nonatopic asthma in 12-year old children and whether they were associated with different risk factors. In particular, we wanted to analyse whether receiving antibiotics during the first week of life was associated with asthma at that age. METHODS: Data were obtained from a longitudinal cohort study of 5654 Swedish children born in 2003. The parents answered questionnaires from the age of six months until 12 years. The response rate at 12 years was 3637/4777 (76%). RESULTS: At 12 years, 6.4% reported current doctor-diagnosed asthma. Treatment with antibiotics during the first week of life was associated with an increased risk of atopic asthma, with an adjusted odds ratio of 2.2 and 95% confidence interval of 1.2-4.2. Being born small for gestational age was associated with an increased risk of nonatopic asthma, with an adjusted odds ratio of 3.8 and 95% confidence interval of 1.1 13.7. Asthma that only occurred with colds was reported by 28%. CONCLUSION: Antibiotic treatment during the first week of life was associated with an increased risk of atopic asthma at 12 years, suggesting an immune-mediated effect. Being born small for gestational age increased the risk of nonatopic asthma. PMID- 29577418 TI - Methadone-Not a magic bullet in melanoma therapy. AB - Methadone (Met) mainly acts as a MU-opioid receptor agonist. Recent evidence pointing towards the role of Met in sensitization of certain cancer cell lines to chemotherapeutic agents has promoted the hypothesis that Met may be a useful adjuvant to cancer chemotherapy. We wanted to address whether Met has, alone or in combination with a chemotherapeutic agent, an effect on melanoma cell viability in vitro. Only a small fraction (4.3%) of our 102 melanoma biobank cell lines with RNA-sequencing data showed expression of the main receptor for Met (OPRM1). We assessed the viability of melanoma cell lines with high, medium or low/no OPRM1 expression (OPRM1high , OPRM1med , OPRM1neg ) 72 hours after treatment with Met alone or combined with cisplatin (Cis). Our analyses show that Met alone did not affect cell viability. While Cis/Met treatment did not have an effect on viability of OPRM1med or OPRM1neg cell lines, it resulted in a slightly decreased cell viability of OPRM1high cells. Clinically, concurrent temozolomide/Met treatment did not have an effect in our single-case report of a patient suffering from uveal melanoma. Taken together, our findings do not provide evidence for recommending Met as an adjuvant to chemotherapy in patients with melanoma. PMID- 29577419 TI - An optimized FAIRE procedure for low cell numbers in yeast. AB - We report an optimized low-input FAIRE-seq (Formaldehyde-Assisted Isolation of Regulatory Elements-sequencing) procedure to assay chromatin accessibility from limited amounts of yeast cells. We demonstrate that the method performs well on as little as 4 mg of cells scraped directly from a few colonies. Sensitivity, specificity and reproducibility of the scaled-down method are comparable with those of regular, higher input amounts, and allow the use of 100-fold fewer cells than existing procedures. The method enables epigenetic analysis of chromatin structure without the need for cell multiplication of exponentially growing cells in liquid culture, thus opening the possibility of studying colony cell subpopulations, or those that can be isolated directly from environmental samples. PMID- 29577420 TI - Infarction of the septomarginal band and tricuspid papillary muscle rupture related to alcohol septal ablation for hypertrophic cardiomyopathy. AB - We presented a 77-year-old man with hypertrophic obstructive cardiomyopathy applied with flail tricuspid leaflet and severe tricuspid regurgitation leading to right heart failure 2 months after the failed septal ablation. The ruptured anterior tricuspid papillary muscle resulted from infarction of the base of anterior papillary muscle of the right ventricle (RV) confirmed by magnetic resonance imaging. As the septomarginal band is frequently lit up by intracoronary contrast that particular attention should be paid to the RV papillary muscles. And, if the papillary muscles or the RV free wall is brightened, then the use of that septal artery should be avoided.

PMID- 29577422 TI - NOTCH4 is a possible novel susceptibility gene for dilated cardiomyopathy in the Chinese population: A case-control study. AB - BACKGROUND: The incidence of dilated cardiomyopathy (DCM) has increased in recent years, and many studies have sought to further improve the general understanding of this condition. Previous studies have demonstrated that some single nucleotide polymorphisms (SNPs) associated with systemic lupus erythematosus also affect susceptibility to DCM, suggesting that immune-related diseases may share similar genetic susceptibility. Recent large-scale and genome-wide association studies have identified NCR3, NOTCH4, CYP1A2, ITGA1, OPRM1, ST8SIA2, and LINC00704 as genetic risk factors associated with cardiac manifestations of neonatal lupus. Here, we aimed to determine whether these SNPs conferred susceptibility to DCM in the Chinese Han population. METHODS: We investigated the relationship between these polymorphisms and DCM risk in 273 patients with DCM and 548 healthy controls. Genotyping was performed using MassArray iPLEX system. RESULTS: Logistic regression analysis indicated that the T allele of rs3134942 in NOTCH4 gene increased the risk of DCM by 61% compared with the G allele (Pa = 6.57 * 10 3 ). The SNP rs3134942 was also significantly associated with increased DCM risk in the additive (Pa = 6.57 * 10-3 ) and dominant models (Pa = 1.01 * 10-2 ). Additionally, rs2472299 in CYP1A2 gene showed suggestive association with reduced risk of DCM in the dominant model (Pa = 4.24 * 10-2 ) and was correlated with smoking status in patients with DCM (Pa = 1.56 * 10-2 ). CONCLUSIONS: Our findings suggested that rs3134942 in NOTCH4 may be involved in DCM risk. Further, studies in larger and ethnically diverse populations are required to confirm the results reported in this study. PMID- 29577423 TI - Intraoperative evaluation of perfusion in free flap surgery: A systematic review and meta-analysis. AB - BACKGROUND: Free flap survival relies on adequate tissue perfusion. We aim to give an overview of the available literature of all objective methods to intraoperatively assess free flap tissue perfusion, and the effects on (partial) flap loss. METHODS: A systematic review and meta-analysis according to the PRISMA guidelines was performed (PubMed, Cochrane Library, Embase) regarding English language articles. Meta-analyses were performed by pooling means and slopes using random-effect models. RESULTS: Sixty-four articles were included reporting on 2369 procedures in 2009 patients with various indications. Reported methods were fluorescence imaging (FI), laser Doppler, oxygen saturation, ultrasound, (dynamic) infrared thermography, venous pressure, and microdialysis. Intraoperative tissue perfusion was adequately measured by the use of FI and laser Doppler, leading to surgical intervention or altered flap design, and increased flap survival. Meta-analysis showed a mean time until onset of the dye to become visible of 18.4 (7.27; 29.46, Q P < 0.001) sec. The relative intensity of the flap compared to the intensity curve of normal tissue was 75.92% (65.85; 85.98, Q P = 0.719). The mean difference in the slope value of the oxygen tensions before and after the anastomosis was -0.09 (-0.12; -0;06 Q P = 0.982). No convincing evidence was found for the use of other methods. CONCLUSIONS: Based on the current literature, FI and laser Doppler are most suitable to intraoperatively measure free flap tissue perfusion, resulting in improved flap survival. However, this review was limited by the available literature. Additional studies are necessary to investigate the predictive value of intraoperative perfusion measurement.

AB - Patients with total knee arthroplasty (TKA) have large deficits in physical performance in comparison to their healthy age-matched peers. Limb asymmetry stemming from less relative load borne by the surgical limb during daily mobility is associated with diminished performance and worsens with greater mobility demands. How common targets of postoperative care, such as muscle weakness, lower limb extension power, residual knee pain, and poor balance confidence can influence asymmetrical limb loading remains unclear. Forty-six patients with unilateral TKA underwent testing of impairments and motion analysis during 10 degrees decline walking at 3 and 6 months postoperatively. At 3 months, only quadriceps femoris strength asymmetry was found to be significantly related to both total support moment (MT ) (beta = 0.431; p < 0.001) and knee extensor moment (MK ) (beta = 0.493; p < 0.001) asymmetry. Again at 6 months, only quadriceps strength asymmetry was related to MT (beta = 0.432; p < 0.001) and MK (beta = 0.534; p < 0.001) asymmetry. Quadriceps strength significantly improved over time in both limbs, however, deficits between limbs remained. Persistent quadriceps weakness is a key factor associated with walking compensation patterns that are limiting the capacity for greater physical performance of patients with TKA. The pronounced asymmetry in limb and knee loading at 3 months remains unchanged until at least 6 months after surgery, and its association with quadriceps strength asymmetry does not substantially change over time. While other factors may also prompt gait compensations, emphasis on improved quadriceps strength should be a focus of efforts to resolve gait compensations and enhance physical performance outcomes.

PMID- 29577424 TI - The first 142 amino acids of glutamate decarboxylase do not contribute to epitopes recognized by autoantibodies associated with Type 1 diabetes. AB - AIMS: Glutamate decarboxylase (GAD) antibodies are the most widely used predictive marker for Type 1 diabetes, but many individuals currently found to be GAD antibody-positive are unlikely to develop diabetes. We have shown previously that radioimmunoassays using N-terminally truncated 35 S-GAD65 (96-585) offer better disease specificity with similar sensitivity to full-length 35 S-GAD65 (1 585). To determine whether assay performance could be improved further, we evaluated a more radically truncated 35 S-GAD65 (143-585) radiolabel. METHODS: Samples from people with recent-onset Type 1 diabetes (n = 157) and their first degree relatives (n = 745) from the Bart's-Oxford family study of childhood diabetes were measured for GAD antibodies using 35 S-labelled GAD65 (143-585). These were screened previously using a local radioimmunoassay with 35 S-GAD65 (1 585). A subset was also tested by enzyme-linked immunosorbent assay (ELISA), which performs well in international workshops, but requires 10 times more serum. Results were compared with GAD antibody measurements using 35 S-GAD65 (1-585) and 35 S-GAD65 (96-585). RESULTS: Sensitivity of GAD antibody measurement was maintained using 35 S-GAD65 (143-585) compared with 35 S-GAD65 (1-585) and 35 S GAD65 (96-585). Specificity for Type 1 diabetes was improved compared with 35 S GAD65 (1-585), but was similar to 35 S-GAD65 (96-585). Relatives found to be GAD antibody-positive using these truncated labels were at increased risk of diabetes progression within 15 years, compared with those positive for GAD(1-585) antibody only, and at similar risk to those found GAD antibody-positive by ELISA. CONCLUSIONS: The first 142 amino acids of GAD65 do not contribute to epitopes recognized by Type 1 diabetes-associated GAD antibodies. Low-volume radioimmunoassays using N-terminally truncated 35 S-GAD65 are more specific than those using full-length GAD65 and offer practical alternatives to the GAD antibody ELISA for identifying children at increased risk of Type 1 diabetes.

AB - BACKGROUND: Nephrolithiasis is a worldwide health problem that affects almost all populations. This study aimed to evaluate the association between rs12654812 of regulator of G protein signaling 14 (RGS14) gene and nephrolithiasis in the Chinese population. METHODS: A total of 1541 participators including 830 cases and 711 controls were included from Guangxi area in China. Age, sex, BMI, smoking status, drinking status, creatinine, uric acid, and urea nitrogen were analyzed between the case group and control group. RESULTS: We found that the G/A+A/A genotypes of rs12654812 had a significantly increased nephrolithiasis risk after adjusting age, sex, BMI, smoking, drinking, and hypertension, compared with G/G genotype (OR = 1.361, 95% CI = 1.033-1.794, P = .029). This hazardous effect was more pronounced in subgroup of age < 50, ever smoking, ever drinking, creatinine normal, and high uric acid. The G/A genotype of rs12654812 also had a significantly increased nephrolithiasis risk compared with G/G genotype. The A allele of rs12654812 significantly increased the risk of nephrolithiasis compared with the G allele after adjusting for age, sex, BMI, smoking, drinking and hypertension (OR = 1.277, 95% CI = 1.013-1.609, P = .038). CONCLUSIONS: Our results suggest that the RGS14 polymorphism is involved in the etiology of nephrolithiasis and thus may be a genetic marker for nephrolithiasis.

AB - Masses on the interatrial septum are usually caused by myxomas or thrombi within a patent foramen ovale. We report a 53-year-old male patient with a hollow mass within the left atrium that was incidentally found during a routine transthoracic echocardiography. Further investigation of the mass with transesophageal two- and three-dimensional echocardiography has revealed that the mass was a localized aneurysm of a patent foramen ovale tunnel. While aneurysms of interatrial septum are relatively common in normal population, to the best of our knowledge, present case is the first report of a localized aneursym of a patent foramen ovale tunnel. PMID- 29577428 TI - Decompression of the anterior thoracic spinal canal using a novel full-endoscopic uniportal transthoracic retropleural technique-an anatomical feasibility study in human cadavers. AB - Surgery for thoracic disc herniation and spinal stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord. Individual planning and various surgical techniques and approaches are required. This anatomical study examines the feasibility of a novel full-endoscopic uniportal technique with a transthoracic retropleural approach for decompression of the anterior thoracic spinal canal. Operations were performed on three fresh adult cadavers. The endoscope used, from RIWOspine, Germany, has a shaft cross-section of 6.9 * 5.9 mm and a 25 degrees view angle. It contains an eccentric intraendoscopic working channel with a diameter of 4.1 mm. A transthoracic retropleural approach was used. The anatomical structures were dissected and the anterior thoracic epidural space was decompressed. The planned steps of the operation were performed on all cadavers. The transthoracic retropleural approach allowed the target region to be accessed easily. The anatomical structures could be identified and dissected. The anterior thoracic epidural space could be decompressed sufficiently. Using the uniportal full endoscopic operation technique with a transthoracic retropleural approach, the anterior thoracic epidural space can be adequately reached. This is a minimally invasive method with the known advantages of an endoscopic technique under continuous irrigation. The retropleural approach allows direct access. The instruments are available for clinical use and have been established for years in other operations on the entire spine. Clin. Anat. 31:716-723, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29577429 TI - Echocardiographic advances in hypertrophic cardiomyopathy: Three-dimensional and strain imaging echocardiography. AB - In the recent past, new ultrasound technologies, such as three-dimensional echocardiography and strain imaging echocardiography, raised up in clinical practice leading to a better assessment of cardiac morphology and performance. These tools may assess regional cardiac mechanics, detecting clinical and subclinical myocardial dysfunction in different settings such as ischemic heart disease, cardiomyopathies, and heart valve diseases. Interesting results derive from patients affected from hypertrophic cardiomyopathy (HCM). Particularly, the mentioned techniques are progressively redefining the role of echocardiography in diagnostic evaluation of HCM variants such as apical HCM, detection of the underlying conditions of increased wall thickness, assessment of subclinical myocardial impairment, and potentially refine risk stratification and prognosis. In this review, we describe the clinical uses of these methodologies and the perspective application in HCM patients. PMID- 29577430 TI - Extremophilic yeasts: the toughest yeasts around? AB - Microorganisms are widely distributed in a multitude of environments including ecosystems that show challenging features to most life forms. The combination of extreme physical and chemical factors contributes to the definition of extreme habitats although the definition of extreme environments changes depending on one's point of view: anthropocentric, microbial-centric or zymo-centric. Microorganisms that live under conditions that cause hard survival are called extremophiles. In particular organisms that require extreme conditions are called true extremophiles while organisms that tolerate them to some extent are termed extremotolerant. Deviation of temperature, pH, osmotic stress, pressure and radiation from the common range delineates extreme environments. Yeasts are versatile eukaryotic organisms that are not frequently considered the toughest microorganisms in comparison with prokaryotes. Nevertheless extremophilic or extremotolerant species are present also within this group. Here a brief description is provided of the main extreme habitats and the metabolic and physiological modifications adopted by yeasts depending on their adverse conditions. Additionally the main extremophilic and extremotolerant yeast species associated with a few extreme habitats are listed. PMID- 29577431 TI - Is podoplanin expression associated with transforming growth factor-beta signaling in odontogenic cysts and tumors? AB - BACKGROUND: Induction of podoplanin by transforming growth factor-beta (TGF-beta) has been shown in a number of lesions but not in odontogenic tumors (OTs). We evaluated the association between these markers in OTs for the first time and compared their expression among the different neoplasms. METHODS: Immunohistochemistry using monoclonal antibody against podoplanin and TGF-beta was performed on 76 odontogenic cysts and tumors. Spearman's correlation coefficient, Kruskal-Wallis, and Mann-Whitney U tests followed by adjustment with Bonferroni were used for statistical analysis (P < .05). RESULTS: A significant difference in podoplanin expression was found among the lesions consisting of solid ameloblastomas, adenomatoid odontogenic tumors, ameloblastic fibromas, odontogenic myxomas (OMs), odontogenic keratocysts, and calcifying odontogenic cysts. Significant differences were observed only between OMs and each of the other neoplasms. Podoplanin immunostaining in the connective tissue was absent in most lesions. TGF-beta was significantly different among the study sample but not between the lesions in paired comparisons. None of the studied OTs showed significant correlations between podoplanin-TGF-beta, in either the epithelium or the stroma. These markers were also descriptively reported in calcifying epithelial odontogenic tumors. CONCLUSIONS: The inductive effect of TGF-beta on podoplanin seems to be limited, if any, in odontogenic lesions. Podoplanin appears to play a role in some aspects of OTs with epithelial or mixed origins. Despite the possible participation of podoplanin in tumorigenesis, it may not necessarily be involved in the aggressive behavior of OTs. PMID- 29577432 TI - Anatomical study of the articular branches innervated the hip and knee joint with reference to mechanism of referral pain in hip joint disease patients. AB - INTRODUCTION: Referred pain in the anterior knee joint is the most common symptom in hip disease patients. The development of referred pain is considered to be related to dichotomizing peripheral sensory fibers. However, no gross anatomical findings identify any dichotomizing fibers innervating both the hip and knee joints. We dissected the femoral and obturator nerves in human cadavers to investigate the distribution of the articular branches in the hip and knee joints. Fourteen embalmed left lower limbs from 14 Japanese adult cadavers (five from females, nine from males, average age 73.8 +/- 14.1 years) were observed macroscopically. The articular branches of the femoral and obturator nerves were dissected at the anterior margin of the groin toward the thigh region. After dissections of the articular nerves of the hip joints, the femoral and obturator nerves were exposed from proximally to distally to identify the articular nerves of the knee joints. The branching pattern of the articular branches in the hip and knee joints was recorded. In six of 14 limbs (42.9%), the femoral nerve supplied articular branches to the anteromedial aspect of both the hip and knee joints. These articular branches were derived from the same bundle of femoral nerve. These gross anatomical findings suggested that dichotomizing peripheral sensory fibers innervate the hip and knee joints and these could relate to the referred pain confirmed in the anterior knee joints of patients with hip disease.

AB - Facial-nerve palsy is the most common complication during facial surgery. However, there are few detailed reports on the distribution of the terminal branches of the facial nerve to the mimetic muscles. This also applies to the communicating branches. The aim of our study was to assess the variability of communicant and terminal branches of the facial nerve in humans. This prospective study involved anatomical dissections and intraoperative electric stimulation of facial nerves. We first performed 30 dissections to define the branching patterns of the extracranial facial nerve, with particular focus on the penetrating points into the mimetic muscles. We then studied and compared these preliminary data with 14 operative facial stimulations conducted during parotidectomies. Each trunk and branch received systematic electrostimulation. The electrostimulation and facial-and-neck movements were analyzed by two independent reviewers. The peripheral branching and intercommunication of the facial branches were highly variable. Combining electrostimulation and dissections, the frontalis muscle, the depressor labii inferioris and the platysma showed little nerve recuperation whereas the sphincter muscles (orbicularis ori and oculi) were anatomically protected. Facial-muscle innervation differed among individuals. We found complex variations in the facial branching mode. Our study highlights the branches and corresponding areas that could be considered anatomically risky. Clin. Anat., 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29577434 TI - Internal and external morphology of mandibular molars: An original micro-CT study and meta-analysis with review of implications for endodontic therapy. AB - The aim of this radiological micro-CT study and meta-analysis was to determine the morphological features of the root canal anatomy of the mandibular molars. The radiological study included micro-CT scans of 108 mandibular first, 120 mandibular second, and 146 mandibular third molars. For our meta-analysis, an extensive search was conducted through PubMed, Embase, and Web of Science to identify articles eligible for inclusion. Data extracted included investigative method (cadaveric, intraoperative, or imaging), Vertucci type of canal configuration, presence/number of canals, roots, apical foramina, apical deltas, and intercanal communications. In the mesial roots of mandibular molars, the most frequent Vertucci type of canal configuration was type IV, except for the mandibular third molar where type I was most common. Type I was most common in the distal root. There were usually two canals in the mesial root and one in the distal root. Two was the most common number of roots, and a third root was most prevalent in Asia. One apical foramen was most common in the distal root and two apical foramina in the mesial root. Intercanal communications were most frequent in the mesial root. Knowledge of the complex anatomy of the mandibular molars can make root canal therapy more likely to succeed. We recommend the use of cone-beam computed tomography before and after endodontic treatment to enable the root anatomy to be accurately described and properly diagnosed, and treatment outcome to be assessed.

PMID- 29577436 TI - Preformed donor-specific antibodies do not affect the 1-year allograft survival in living donor liver transplantation. AB - The effect of preformed donor-specific antibodies (DSAs) on liver transplantation (LT) remains unclear, especially in the field of living donor LT (LDLT). Herein, we evaluated the prevalence of preformed DSAs and their effect on graft outcome in LDLT in the first year following surgery. Using the Luminex(r) Single Antigen assay, we analyzed the preoperative sera of 61 adult LDLT recipients between 2014 and 2015. Clinical outcomes and pathologic findings including complement component 4d (C4d) expression in the first year after LT were retrospectively reviewed. Regardless of the class of DSA, DSAs with mean fluorescence intensity (MFI) >=1000 were defined as positive and preformed DSA with MFI >=5000 was defined as strongly positive. Fifteen patients (24.6%) had preformed DSAs, and 8 patients (13.1%) showed strongly positive preformed DSAs. Among 15 DSA positive patients, 2 (13.3%) showed persistent DSAs after LDLT. No de novo DSAs were noted in patients without preformed DSAs. Preformed DSAs were not related to graft dysfunction, laboratory values, or C4d expression or other pathologic findings in the first year of LDLT. In conclusion, preformed DSAs persisted during follow-up in 13.3% of cases and did not have adverse effect on histologic or clinical outcomes in the first year of LDLT.

PMID- 29577437 TI - Oral administration of cernitin pollen extract (Cernilton(r) ) for 30 days might be useful to avoid unnecessary biopsy in prostate biopsy candidates: A preliminary study. AB - OBJECTIVES: To assess the effect of cernitin pollen extract on serum prostate specific antigen level prostate biopsy candidates, and to develop an ideal protocol to avoid an unnecessary biopsy procedure. METHODS: A total of 61 patients were administrated cernitin pollen extract tablets (two tablets t.i.d.) for 30 days, and then underwent a prostate biopsy with >=12 systematic and targeted biopsy cores obtained. Serum prostate-specific antigen levels were examined before and after administration of the pollen extract, and the change in serum prostate-specific antigen and the rate of change were analyzed in relation to negative and positive biopsy results for cancer. RESULTS: The mean change in serum prostate-specific antigen and rate of change after administration of cernitin pollen extract in all patients were -0.6 +/- 1.4 ng/mL and -7.6 +/- 16.1%, respectively, which were significantly different from the baseline values (P = 0.0003 and P = 0.0005, respectively). When prostate-specific antigen change values and rates were compared between patients negative and positive for cancer, a significant difference between those groups was observed (P = 0.04 and P = 0.03, respectively). CONCLUSIONS: The present study is the first to show that an ideal protocol using cernitin pollen extract has the potential to avoid an unnecessary prostate biopsy procedure in patients with elevated prostate-specific antigen, possibly caused by inflammation. Additional studies with greater numbers of participants are required to confirm our findings and develop an ideal protocol. PMID- 29577439 TI - Glutamatergic cells in the periaqueductal gray matter mediate sensory inputs after bladder stimulation in freely moving rats. AB - OBJECTIVES: To determine the phenotype of the ventrolateral part of the periaqueductal gray matter neurons after bladder stimulation. METHODS: In the experimental group, electrical stimulation of the bladder was carried out under freely moving condition by a bipolar stimulation electrode implanted in the bladder wall. Thereafter, the brain sections were processed for immunohistochemical analysis using antibodies against c-Fos (neuronal activation marker) together with one of the following: tyrosine hydroxylase (dopaminergic cell marker), vesicular glutamate transporter (glutamatergic cell marker), serotonin, glutamate decarboxylase (glutamate decarboxylase 67, gamma aminobutyric acid cell marker) and neuronal nitric oxide synthase. We used design based confocal stereological analysis to quantify the immunohistochemically stained sections. RESULTS: A significant increase in the number of c-Fos-positive cells in the ventrolateral part of the periaqueductal gray matter after stimulation was found. Furthermore, the ratio of c-Fos cells double labeled with vesicular glutamate transporter was significantly higher in the ventrolateral part of the periaqueductal gray matter region in the stimulated compared with the sham group. Quantitative analysis of the other four cell types did not show any significant difference. CONCLUSION: These findings suggest that glutamatergic neurotransmission in the ventrolateral part of the periaqueductal gray matter is seemingly the main pathway to be activated after receiving sensory signals from the bladder.

AB - OBJECTIVES: To assess the diagnostic ability of a pixel intensity-based analysis in evaluating the magnetic resonance imaging characteristics of small renal masses, especially in differentiating fat-poor angiomyolipoma from renal cell carcinoma. METHODS: T2-weighted images from 121 solid small renal masses (<4 cm) without visible fat (14 fat-poor angiomyolipomas, 92 clear cell renal cell carcinomas, six chromophobe renal cell carcinomas and nine papillary renal cell carcinomas) were retrospectively evaluated. An intensity ratio curve was plotted using intensity ratios, which were ratios of signal intensities of tumor pixels (each pixel along a linear region of interest drawn across the renal tumor on T2 weighted image) to the signal intensity of a normal renal cortex. The diagnostic ability of the intensity ratio curve analysis was evaluated. RESULTS: The tumors were classified into three types: intensity ratio fat-poor angiomyolipoma (n = 19) with no pseudocapsule, iso-low intensity and no heterogeneity; intensity ratio clear cell renal cell carcinoma (n = 76) with a pseudocapsule, iso-high intensity and heterogeneity; and other type of intensity ratio (n = 26), including tumors that did not fall into the above two categories. The sensitivity/specificity/accuracy of the intensity ratio curve analysis in diagnosing fat-poor angiomyolipoma was 93%/94%/94%, respectively. When the intensity ratio curve analysis was applied only to the tumor with undetermined radiological diagnosis, the sensitivity for diagnosing fat-poor angiomyolipoma compared with subjective reading alone significantly improved (93% vs 50%; P = 0.014). CONCLUSIONS: Our novel semiquantitative model for combined assessment of key features of fat-poor angiomyolipoma, including low intensity, homogeneity and absence of a pseudocapsule on T2-weighted image, might make diagnosis of fat-poor angiomyolipoma more accurate. PMID- 29577442 TI - Diet and risk of myopia in three-year-old Singapore children: the GUSTO cohort. AB - BACKGROUND: To investigate the relationship between dietary intakes at six, nine and 12 months and risk of myopia in three-year-old children in a birth cohort. METHODS: Three hundred and seventeen children from the Growing Up in Singapore Towards Healthy Outcomes (GUSTO) study were included. Dietary intake at six, nine and 12 months of age was ascertained using either 24-hour recalls or three-day food diaries completed by parents. Cycloplegia was achieved with three drops of one per cent cycloplentolate instilled at five minute intervals. Cycloplegic autorefraction and axial length (AL) were measured at three years of age with a table-mounted autorefractor and optical biometer, respectively. Myopia was defined as spherical equivalent (SE) of <= -0.50 D. Associations of dietary intake with SE, AL and myopia were examined by single dietary factor models using two multivariable regression models. Model 1 included adjusting for age, gender and total energy intake. Model 2 included additional adjustments for ethnicity, time spent outdoors, maternal education and parental myopia. RESULTS: In the single dietary factor adjusted models, dietary intakes at six, nine and 12 months were not associated with SE, AL and myopia. In model 1, protein, fat and carbohydrate intakes were not associated with SE, AL and myopia at any of the three time points (p > 0.05). In model 2, protein, fat and carbohydrate intakes were not associated with SE, AL and myopia at any of the three time points (p > 0.05). CONCLUSIONS: In this study, there was no evidence that diet at ages six, nine and 12 months was related to SE, AL or myopia at age three years. Further prospective studies with larger sample sizes are needed to understand the influence of diet on eye development in young children.

AB - The nanopore can generate an electrochemical confinement for single-molecule sensing that help understand the fundamental chemical principle in nanoscale dimensions. By observing the generated ionic current, individual bond-making and bond-breaking steps, single biomolecule dynamic conformational changes and electron transfer processes that occur within pore can be monitored with high temporal and current resolution. These single-molecule studies in nanopore confinement are revealing information about the fundamental chemical and biological processes that cannot be extracted from ensemble measurements. In this Concept article, we introduce and discuss the electrochemical confinement effects on single-molecule covalent reactions, conformational dynamics of individual molecules and host-guest interactions in protein nanopores. Then, we extend the concept of nanopore confinement effects to confine electrochemical redox reactions in solid-state nanopores for developing new sensing mechanisms. PMID- 29577446 TI - The anatomy of the male inferior hypogastric plexus: What should we know for nerve sparing surgery. AB - The aim of this study was to investigate the nerve supply to the structures in the male lesser pelvis and review its clinical relevance, especially during nerve sparing surgery. Three formalin-embalmed and 16 Thiel-embalmed male hemipelves were used. They were microdissected after repeated treatments with nitric acid diluted 1:10 with milliQ-water. The inferior hypogastric plexus (IHP) is a fan like structure lateral from the rectum on the fascia of the levator ani. Nerves emerging from the proximal, solid part of the plexus follow the internal iliacal vessels and reach the prostate from dorsolateral. The innervation of the urethra and the corpora cavernosa derives from two origins: one follows the ejaculatory duct and the seminal vesicle, reaching the proximal urethra and the prostate from dorsal; the other follows the inferior vesical artery to reach the prostate from lateral, and then forms the neurovascular bundle on both sides of the prostatic fascia, spreading to the pelvic floor muscles and the corpora cavernosa along with the distal urethra. A connection between the two parts was demonstrated in approximately one third of the samples investigated. The nerve supply to the urinary bladder, the urethra, and the corpora cavernosa emerges mainly from the IHP. The innervation of the proximal urethra and its autonomic muscular structures has a dorsal (ejaculatory duct) and lateral (inferior vesical artery) origin. To maintain good erectile and continence function it is important to save both the dorsal and lateral neurovascular roots. Clin. Anat. 31:788-796, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 29577447 TI - High terbinafine resistance in Trichophyton interdigitale isolates in Delhi, India harbouring mutations in the squalene epoxidase gene. AB - In the last few years, infections caused by dermatophytes along with a concomitant increase in the number of difficult to treat cases have increasingly been recognised, indicating that dermatophytosis remains a challenging public health problem. The majority of infections are caused by Trichophyton rubrum and Trichophyton mentagrophytes complex. Terbinafine, an allylamine antifungal used orally and topically is considered to be a first-line drug in the therapy of dermatophyte infections. Terbinafine resistance has been predominately attributed to point mutations in the squalene epoxidase (SQLE) target gene a key enzyme in the ergosterol biosynthetic pathway leading to single amino acid substitutions. Here, we report the largest series of 20 terbinafine-resistant Trichophyton interdigitale isolates obtained predominately from cases of tinea corporis/cruris in three hospitals in Delhi, India exhibiting elevated MICs (4 to >=32 MUg/mL) to terbinafine and all harbouring single-point mutations Leu393Phe or Phe397Leu in the SQLE gene. In 12 (60%) T. interdigitale isolates, the Phe397Leu substitution was observed, whereas in the remaining 8 (40%) isolates the substitution Leu393Phe was reported for the first time in T. interdigitale. Furthermore, 10 susceptible T. interdigitale isolates (0.125-2 MUg/mL) had a wild-type genotype. Remarkably, considerably high terbinafine resistance rate of 32% was observed among 63 T. interdigitale isolates identified by sequencing of the internal transcribed spacer region. This high level of terbinafine resistance of Indian dermatophyte isolates is worrisome warranting antifungal susceptibility testing and mutation analysis for monitoring this emerging resistance. PMID- 29577448 TI - Surgical approach, cost, and complications of appendectomy in kidney transplant recipients. AB - Kidney transplant recipients (KTRs) have greater morbidity and length of stay (LOS) following certain surgical procedures than non-KTR. Given that appendectomy is one of the most common surgical procedures, we investigated differences in outcomes between 1336 KTR and 2 640 247 non-KTR postappendectomy at transplant and nontransplant centers in the United States from 2000 to 2011, using NIS data and adjusting for patient-level and hospital-level factors. Postoperative complications were identified using ICD-9 codes. Among KTR, there were no post appendectomy in-hospital deaths, compared to a 0.2% in non-KTR (P = .5). Overall complications were similar among KTR and non-KTR (17.0% vs 11.6%; aOR:0.77 1.121.61 ). LOS and costs were greater for KTR compared to non-KTR (LOS ratio 1.19 1.311.45 ; cost ratio 1.11 1.171.26 ). Only 44.8% of KTR had laparoscopic approach compared to 54.5% of non-KTR, but had similar complication rates (10.6 vs 8.7%, P = .5). When treated at transplant centers, KTR had similar complications (aOR 0.44 0.791.43 ), but longer LOS (ratio 1.21 1.371.55 ) and greater hospital-associated costs (ratio 1.19 1.291.41 ) than non-KTR. Conversely, at nontransplant centers, KTR and non-KTR had similar complications (aOR 0.75 1.232.0 ), LOS (ratio 0.84 0.961.09 ), and cost (ratio 0.93 1.011.10 ).

AB - BACKGROUND: Sorafenib has shown survival benefits in patients with advanced HCC; however, limited data are available on its role in OLT recipients with advanced HCC in the explant. AIM: Evaluate the role of preemptive sorafenib therapy on HCC recurrence and survival after OLT with advanced HCC on explant pathology. METHODS: We retrospectively reviewed the outcome after OLT of all HCC recipients with advanced HCC in the explant pathology from 04/2006 to 12/2012 based on preemptive treatment with sorafenib. RESULTS: During the observation period, 217 HCC recipients underwent OLT; 50 explants revealed advanced HCC. After exclusion of 5 patients who were lost to follow-up, 45 LT recipients were finally included for analysis. Recipients were grouped as sorafenib Gr (N = 25) and nonsorafenib Gr (N = 20). Both recurrence-free survival (RFS) (P = .67) and overall survival were similar between groups (P = .53) on Kaplan-Meier analysis. Additionally, sorafenib use was neither associated with HCC recurrence-free survival (HR 0.74, 95% CI [0.32-1.70]; P = .48) nor overall survival (HR 0.92, 95% CI [0.39-2.15], P = .84) on multivariate Cox proportional hazard model with sorafenib use as time varying covariates. CONCLUSION: Preemptive treatment with sorafenib in OLT recipients with high-risk features in explant does not improve HCC recurrence free or overall survival.

AB - The American Psychiatric Association and the World Health Organization provide distinct trauma-based diagnoses in the fifth edition of the Diagnostic and Statistical Manual (DSM-5), and the forthcoming 11th version of the International Classification of Diseases (ICD-11), respectively. The DSM-5 conceptualizes posttraumatic stress disorder (PTSD) as a single, broad diagnosis, whereas the ICD-11 proposes two "sibling" disorders: PTSD and complex PTSD (CPTSD). The objectives of the current study were to: (a) compare prevalence rates of PTSD/CPTSD based on each diagnostic system; (b) identify clinical and behavioral variables that distinguish ICD-11 CPTSD and PTSD diagnoses; and (c) examine the diagnostic associations for ICD-11 CPTSD and DSM-5 PTSD. Participants in a predominately female clinical sample (N = 106) completed self-report scales to measure ICD-11 PTSD and CPTSD, DSM-5 PTSD, and depression, anxiety, borderline personality disorder, dissociation, destructive behaviors, and suicidal ideation and self-harm. Significantly more people were diagnosed with PTSD according to the DSM-5 criteria (90.4%) compared to those diagnosed with PTSD and CPTSD according to the ICD-11 guidelines (79.8%). An ICD-11 CPTSD diagnosis was distinguished from an ICD-11 PTSD diagnosis by higher levels of dissociation (d = 1.01), depression (d = 0.63), and borderline personality disorder (d = 0.55). Diagnostic associations with depression, anxiety, and suicidal ideation and self harm were higher for ICD-11 CPTSD compared to DSM-5 PTSD (by 10.7%, 4.0%, and 7.0%, respectively). These results have implications for differential diagnosis and for the development of targeted treatments for CPTSD. PMID- 29577451 TI - Positive Jacquet's sign in traction alopecia. PMID- 29577452 TI - The Concept of "Noble, Heteroatom-Doped Carbons," Their Directed Synthesis by Electronic Band Control of Carbonization, and Applications in Catalysis and Energy Materials. AB - Carbonization of organic compounds with a highest occupied molecular orbital (HOMO) level more positive than 1.3 V practically automatically results in highly sp2 -conjugated, heteroatom-doped carbons. Due to the stability of the starting compounds, carbon bond formation is restricted to result in morphologies with a surprisingly high local order which as such are noble, i.e., they are hard to oxidize and combust. The work function of electrons in these systems is so positive that the systems usually accept electrons, i.e., they oxidize other matter rather than being oxidized. Such noble, heteroatom-doped carbons have been proven to be efficient, metal-free electrocatalysts, but can be also beneficially used in the manufacturing of carbon nanomaterials for energy applications or as highly active, non-innocent catalytic supports. PMID- 29577453 TI - Highly Elastic and Ultratough Hybrid Ionic-Covalent Hydrogels with Tunable Structures and Mechanics. AB - Hybrid ionically-covalently crosslinked double-network (DN) hydrogels are attracting increasing attention on account of their self-recovery ability and fatigue resistance, but their relative low mechanical strength and tedious performance adjustment severely limit their applications. Herein, a new strategy to concurrently fabricate hybrid ionic-covalent DN hydrogels and modulate their structures and mechanics is reported, in which an in situ formed chitosan ionic network is incorporated by post-crosslinking the chitosan-based composite hydrogel using multivalent anions solutions. The obtained hybrid DN hydrogels exhibit predominant mechanical properties including superior elastic modulus, high tensile strength, and ultrahigh fracture energy because of the more efficient energy dissipation of rigid short-chain chitosan network. Notably, the swollen hydrogels still remain mechanically strong and tough even after immersion in water for 24 h. More significantly, simply changing the post-crosslinking time can vary the compactness and rigidity of the chitosan network in situ, achieving flexible and efficient modulation of the structures and mechanics of the hybrid DN hydrogels. This study opens up a new horizon in the preparation and regulation of DN hydrogels for promising applications in tissue scaffolds, actuators, and wearable devices. PMID- 29577454 TI - Tumor necrosis factor receptor-associated factor 6 mediated the promotion of salivary adenoid cystic carcinoma progression through Smad-p38-JNK signaling pathway induced by TGF-beta. AB - BACKGROUND: Tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6) has been proved to play an important role in tumorigenesis, invasion, and metastasis. However, its precise role salivary adenoid cystic carcinoma (SACC) has not been determined. The aim of this study was to explore the role of TRAF6 in SACC including invasion and metastasis of SACC cells. MATERIALS AND METHODS: Immunohistochemistry and quantitative real-time PCR were performed in SACC tissues paired with their adjacent normal tissues to analyze the expression of TRAF6. Downstream proteins expression was explored when TRAF6 was knockdown by siRNA. RESULTS: The results show that TRAF6 is upregulated in SACC samples, especially in SACC with metastasis, which is closely correlated with an aggressive phenotype (P = .0073) and shorter life survival span (P = .0061) in SACC patients. Knockdown of TRAF6 can attenuate the promotion effect of SACC cell invasion induced by TGF-beta. Western blot results also showed that silencing TRAF6 expression can inhibit the activation of SMAD2, SMAD3, ERK, p38, and JNK induced by TGF-beta in SACC cells. CONCLUSION: These data suggested that TRAF6 regulates TGF-beta-mediated SACC progression through SMAD2/3-ERK-p38-JNK cascades.

AB - Intermediate polysulfides (Sn , where n = 2-8) play a critical role in both mechanistic understanding and performance improvement of lithium-sulfur batteries. The rational management of polysulfides is of profound significance for high-efficiency sulfur electrochemistry.

Two schools of thoughts for polysulfide management are proposed, their advantages and disadvantages are compared, and future developments are discussed. PMID- 29577455 TI - Diminished impact of cytomegalovirus infection on graft vasculopathy development in the antiviral prophylaxis era - a retrospective study. AB - Evidence concerning an association between cytomegalovirus (CMV) infection and accelerated cardiac allograft vasculopathy (CAV) is inconclusive. Data were analyzed retrospectively from 297 consecutive heart transplants between 1.1.2002 and 31.12.2012. Patients <=18 years of age, survival, and follow-up <=1-year post transplant and patients with early CAV were excluded. CMV-infection was diagnosed and monitored closely in the first year. CAV was diagnosed by coronary angiography via left heart catheterization, and results were categorized according to the International Society of Heart and Lung Transplantation (ISHLT) scoring system. Risk factors for CAV were tested in a multivariable model. Median follow-up was 7.5 years (IQR: 5.6-10.3). CMV infection in the first year after transplantation occurred in 26% of patients (n = 78), CMV disease in 5% (n = 15). CAV >=1 ISHLT was detected in 36% (n = 108). Incidence of CAV >1 ISHLT and severity of CAV increased over time. No statistically significant association between CMV infection and disease within the first year and risk of CAV after 1 year post-HTx was detected in the univariate (P = 0.16) and multivariable [hazard ratio (HR), 1.36; confidence interval (CI), 0.89-2.07; P = 0.16] Cox regression. In the multivariable Cox regression, donor age (HR, 1.04; 95% CI, 1.02-1.06; P < 0.01) and acute cellular rejection (ACR) >=2R in the first year after HTx (HR, 1.77; 95% CI, 1.06-2.95; P = 0.03) were independent risk factors for CAV development. In our cohort, CMV infection and disease in the first year after transplantation did not significantly influence the risk of CAV in the long-term follow-up.

AB - The chemotherapy of glioblastoma is severely hindered by the immunosuppressive tumor microenvironment, especially the tumor growth factor beta (TGF-beta), an immunosuppressive cytokine. In this study, it is proposed to employ RNAi-based immunomodulation to modify the tumor immune microenvironment and improve the effect of chemotherapy. Herein, a nanotheranostic system (Angiopep LipoPCB(Temozolomide+BAP/siTGF-beta), ALBTA) with dual targeting and ROS response is established for intracranial glioblastoma treatment. The traceable nanoparticles exhibit strong siRNA condensation, high drug loading efficiency, good serum stability, and magnetic property. They can efficiently cross the blood brain barrier and target to glioblastoma cells via receptor-mediated transcytosis. The zwitterionic lipid (distearoyl phosphoethanol-amine polycarboxybetaine lipid) in ALBTA promotes endosomal/lysosomal escape, and thus enhances the cytotoxicity of temozolomide and improves gene silencing efficiency of siTGF-beta. ALBTA significantly improves the immunosuppressive microenvironment and prolongs the survival time of glioma-bearing mice. Moreover, ALBTA can be accurately traced by MRI in brain tumors. The study indicates that this immunochemotherapeutic platform can serve as a flexible and powerful synergistic system for treatment with brain tumors as well as other brain diseases in central nervous system.

AB - Cancer is one of the most deadly diseases threatening the lives of humans. Although many treatment methods have been developed to tackle cancer, each modality of cancer treatment has its own limitations and drawbacks. The development of minimally invasive treatment modalities for cancers remains a great challenge. Near-infrared (NIR) light-activated nanomaterial-mediated phototherapies, including photothermal and photodynamic therapies, provide an alternative means for spatially and temporally controlled minimally invasive treatments of cancers. Nanomaterials can serve as nanocargoes for the delivery of chemo-drugs, diagnostic contrast reagents, and organic photosensitizers, and can be used to directly generate heat or reactive oxygen species for the treatment of tumors without the need for organic photosensitizers with NIR-light irradiation. Here, current progress in NIR-light-activated nanomaterial-mediated photothermal therapy and photodynamic therapy is summarized. Furthermore, the effects of size, shape, and surface functionalities of nanomaterials on intracellular uptake, macrophage clearance, biodistribution, cytotoxicities, and biomedical efficacies are discussed. The use of various types of nanomaterials, such as gold nanoparticles, carbon nanotubes, graphene, and many other inorganic nanostructures, in combination with diagnostic and therapeutic modalities for solid tumors, is briefly reviewed. PMID- 29577459 TI - Astragaloside IV reverses MNNG-induced precancerous lesions of gastric carcinoma in rats: Regulation on glycolysis through miRNA-34a/LDHA pathway. AB - This study was designed to investigate the precancerous lesions of gastric carcinoma (PLGC)-reversing mechanisms of astragaloside IV (ASIV) in N-methyl-N' nitro-N-nitrosoguanidine (MNNG)-induced PLGC rats. All rats were sacrificed after 10-week treatment. Gastric tissue was analyzed by using histopathology and electron microscope. To be fully evidenced, LDHA, p53, TIGAR, MCT1, MCT4, HIF 1alpha, CD147, and miRNA-34a were detected by Western blotting and Real-time Quantitative polymerase chain reaction (RT-qPCR). As histopathology and electron microscope showed, it can be clearly observed that the area of dysplasia was reduced in ASIV groups, indicating that MNNG-induced PLGC was markedly reversed by ASIV. Moreover, compared with model group, a significant decrease in gene expressions of LDHA, MCT1, MCT4, HIF-1alpha, CD147, and TIGAR was observed whereas miRNA-34a level was increased in ASIV groups. A significant up-regulation induced by MNNG in protein levels of LDHA, MCT1, MCT4, HIF-1alpha, and CD147 was attenuated in rats treated with ASIV. In contrast, the decreased expression of TIGAR was restored by ASIV. Interestingly, up-regulation of p53 expression induced by MNNG was further increased in ASIV groups. In brief, these results implied that abnormal glycolysis was relieved by ASIV via regulation of the expressions of LDHA, p53, TIGAR, MCT1, MCT4, HIF-1alpha, CD147, and miRNA-34a. PMID- 29577460 TI - Gene expression profiling reveals the plausible mechanisms underlying the antitumor and antimetastasis effects of Andrographis paniculata in esophageal cancer. AB - Esophageal cancer (EC) is a seriously invasive malignancy with high mortality and poor prognosis. Metastasis of EC is the major cause of mortality. Our studies previously demonstrated that a herbal medicine Andrographis paniculata (AP) significantly suppressed EC growth and metastasis in vitro and in vivo. However, the underlying mechanisms responsible for these effects have not yet been systematically elucidated. In this context, gene expression profiling of AP treated squamous EC cells (EC-109) was performed to reveal the regulatory mechanisms of AP in antitumor and antimetastasis signaling pathways using gene expression microarray analysis. Differentially expressed genes were identified by Affymetrix Gene Chip, followed by the real-time polymerase chain reaction validation. The results showed that the canonical pathways were significantly regulated by AP treatment, including multiple genes related to proliferation, apoptosis, intercellular adhesion, metastatic processes, and drug resistance, such as WNT, TGF-beta, MAPK and ErbB signaling pathways, and ATP-binding cassette transporter subfamily members. This genomic study emerges candidate molecular targets and pathways to reveal the mechanisms involved in AP's effects, which provides scientific evidence to support the clinical application of AP in EC treatment.

AB - The crystalline phase beta-[N(CH3 )4 ]2 HP3 O9 undergoes a reversible phase transition to gamma-[N(CH3 )4 ]2 HP3 O9 , which was studied by dynamic scanning calorimetry and X-ray diffraction. The rotational dynamics of the anion [P3 O9 ]3 were evident from variable temperature 31 P magic angle spinning (MAS) NMR spectroscopy. The rotational dynamics could be simulated with a 3-site jump model, which yields spectra in good agreement with experiment. An activation energy of 0.6 eV could be estimated from line shape analysis. Impedance spectra reflect a bulk proton conductivity of gamma-[N(CH3 )4 ]2 HP3 O9 of 6.9*10-5 S cm 1 at 240 degrees C and an activation energy of approximately 1.0 eV. Thus this salt features bulk protonic motion, while local rotational anionic motion happens with activation energies of the same order, as suggested by the paddle-wheel mechanism.

PMID- 29577467 TI - Post-cationic Modification of a Pyrimidine-Based Conjugated Microporous Polymer for Enhancing the Removal Performance of Anionic Dyes in Water. AB - Ionic porous organic polymers have attracted much attention due to their broad applications in catalysis, energy storage/conversion, proton conduction, etc. In this paper, an ionic porous organic polymer, CMP-PM-Me, was synthesized through post-synthetic modification of a pyrimidine-based conjugated microporous polymer, CMP-PM, which was constructed by the palladium catalyzed Sonogashira reaction of 1,3,5-triethynylbenzen and 2,5-dibromopyrimidine. These two polymers are porous with Brunauer-Emmett-Teller surface areas of 416 and 241 m2 g-1 for CMP-PM and CMP-PM-Me, respectively. Due to the cationic framework, CMP-PM-Me exhibits a much faster and more efficient adsorption performance to anionic dyes such as Congo red (CR) and methyl orange (MO) than that of CMP-PM with a neutral framework. The uptakes for CR are 400.0 mg g-1 for CMP-PM-Me and 344.8 mg g-1 for CMP-PM, respectively. Furthermore, CMP-PM-Me could quickly and drastically separate anionic dyes from the binary mixed solution of anionic and nonanionic dyes within a short time. This work not only enriches the family of ionic organic porous polymers and widens their synthetic utility, but also demonstrates their applications in the adsorption and separation of anionic dyes in water.

AB - The impacts of drought are expanding worldwide as a consequence of climate change. However, there is still little knowledge of how species respond to long term selection in seasonally dry ecosystems. In this study, we used QST -FST comparisons to investigate (i) the role of natural selection on population genetic differentiation for a set of functional traits related to drought resistance in the seasonally dry tropical oak Quercus oleoides and (ii) the influence of water availability at the site of population origin and in experimental treatments on patterns of trait divergence. We conducted a thorough phenotypic characterization of 1912 seedlings from ten populations growing in field and greenhouse common gardens under replicated watering treatments. We also genotyped 218 individuals from the same set of populations using eleven nuclear microsatellites. QST distributions for leaf lamina area, specific leaf area, leaf thickness and stomatal pore index were higher than FST distribution. Results were consistent across growth environments. Genetic differentiation among populations for these functional traits was associated with the index of moisture at the origin of the populations. Together, our results suggest that drought is an important selective agent for Q. oleoides and that differences in length and severity of the dry season have driven the evolution of genetic differences in functional traits. PMID- 29577470 TI - Giant Thermal Expansion in 2D and 3D Cellular Materials. AB - When temperature increases, the volume of an object changes. This property was quantified as the coefficient of thermal expansion only a few hundred years ago. Part of the reason is that the change of volume due to the variation of temperature is in general extremely small and imperceptible. Here, abnormal giant linear thermal expansions in different types of two-ingredient microstructured hierarchical and self-similar cellular materials are reported. The cellular materials can be 2D or 3D, and isotropic or anisotropic, with a positive or negative thermal expansion due to the convex or/and concave shape in their representative volume elements respectively. The magnitude of the thermal expansion coefficient can be several times larger than the highest value reported in the literature. This study suggests an innovative approach to develop temperature-sensitive functional materials and devices. PMID- 29577468 TI - Maternal-fetal cross talk through cell-free fetal DNA, telomere shortening, microchimerism, and inflammation. AB - There exists a strong correlation between unscheduled inflammation at the maternal-fetal interface and the continuum of pregnancy complications. In normal pregnancy, immunological tolerance is established to protect the semi-allogeneic fetus. There has been extensive research on how the immunity, endovascular trophoblast migration, and hormonal nexus are orchestrated during pregnancy at the maternal-fetal interface to program a normal pregnancy outcome. It is not clear what contributes to the plasticity of uterine immune tolerance, fetal survial, and long-term post-partum health of the mother and the offspring. Old and new concepts have reemerged and emerged that include cell-free fetal DNA (cffDNA), telomere shortening, microchimerism involving bidirectional migration of maternal and fetal cells, and pregnancy as a stress factor. The question is how these pathways converge in a gestational age-dependent manner to contribute to the health of the mother and the offspring later in life and respond to an array of inflammatory challenges. In this Review, we provide pertinent discussion on maternal-fetal cross talk through cffDNA, telomere shortening, and microchimerism in the context of inflammatory and anti-inflammatory settings, particularly how these pathways lead to normal and adverse pregnancy outcomes. PMID- 29577472 TI - Polypyridyl Metallo-Organic Assemblies for Electrochromic Applications. AB - Electrochromic films undergo optical changes in response to a redox stimulus. This intriguing phenomenon can be used for a wide range of applications, including smart windows, sensors, color displays, and memory elements. Despite the rapid progress of late, designing suitable electrochromic materials that offer low-cost production, appealing colors, and pronounced optical contrast with high efficiency, as well as long-term stability remains an engineering challenge. Solid-state metal oxides, liquid crystals, and organic polymers have been for many years the leading candidates, successfully making their way into commercial products. An alternative class of materials relies on metal complexes that can be processed from solution, offer a variety of colors, and have metal-centered stable and reversible redox chemistry. These metallo-organic materials possess a full range of electrochromic properties, including ultrahigh coloration efficiencies, and cyclic stability. Here, some of the recent scientific developments in this field are highlighted. PMID- 29577471 TI - Focal, but not global, cerebral ischaemia causes loss of myenteric neurons and upregulation of vasoactive intestinal peptide in mouse ileum. AB - Reduced blood flow to the brain induces cerebral ischaemia, potentially causing central injury and peripheral complications including gastrointestinal (GI) dysfunction. The pathophysiology behind GI symptoms is suspected to be neuropathy in the enteric nervous system (ENS), which is essential in regulating GI function. This study investigates if enteric neuropathy occurs after cerebral ischaemia, by analysing neuronal survival and relative numbers of vasoactive intestinal peptide (VIP) and neuronal nitric oxide synthase (nNOS) expressing neurons in mouse ileum after three types of cerebral ischaemia. Focal cerebral ischaemia, modelled by permanent middle cerebral artery occlusion (pMCAO) and global cerebral ischaemia, modelled with either transient occlusion of both common carotid arteries followed by reperfusion (GCIR) or chronic cerebral hypoperfusion (CCH) was performed on C56BL/6 mice. Sham-operated mice for each ischaemia model served as control. Ileum was collected after 1-17 weeks, depending on model, and analysed using morphometry and immunocytochemistry. For each group, intestinal mucosa and muscle layer thicknesses, neuronal numbers and relative proportions of neurons immunoreactive (IR) for nNOS or VIP were estimated. No alterations in mucosa or muscle layer thicknesses were noted in any of the groups. Loss of myenteric neurons and an increased number of VIP-IR submucous neurons were found in mouse ileum 7 days after pMCAO. None of the global ischaemia models showed any alterations in neuronal survival or relative numbers of VIP- and nNOS-IR neurons. We conclude that focal cerebral ischaemia and global cerebral ischaemia influence enteric neuronal survival differently. This is suggested to reflect differences in peripheral neuro-immune responses. PMID- 29577473 TI - A Supercompressible, Elastic, and Bendable Carbon Aerogel with Ultrasensitive Detection Limits for Compression Strain, Pressure, and Bending Angle. AB - Ultralight and compressible carbon materials have promising applications in strain and pressure detection. However, it is still difficult to prepare carbon materials with supercompressibility, elasticity, stable strain-electrical signal response, and ultrasensitive detection limits, due to the challenge in structural regulation. Herein, a new strategy to prepare a reduced graphene oxide (rGO) based lamellar carbon aerogels with unexpected and integrated performances by designing wave-shape rGO layers and enhancing the interaction among the rGO layers is demonstrated. Addition of cellulose nanocrystalline and low-molecular weight carbon precursors enhances the interaction among rGO layers and thus produces an ultralight, flexible, and superstable structure. The as-prepared carbon aerogel displays a supercompressibility (undergoing an extreme strain of 99%) and elasticity (100% height retention after 10 000 cycles at a strain of 30%), as well as stable strain-current response (at least 10 000 cycles). Particularly, the carbon aerogel is ultrasensitive for detecting tiny change in strain (0.012%) and pressure (0.25 Pa), which are the lowest detection limits for compressible carbon materials reported in the literature. Moreover, the carbon aerogel exhibits excellent bendable performance and can detect an ultralow bending angle of 0.052 degrees . Additionally, the carbon aerogel also demonstrates its promising application as wearable devices. PMID- 29577474 TI - Prospective evaluation of a combination of fungal biomarkers for the diagnosis of invasive fungal disease in high-risk haematology patients. AB - We prospectively evaluated a combination of fungal biomarkers in adult haematology patients with focus on their clinical utility at different time points during the course of infection. In total, 135 patients were monitored once to twice weekly for serum (1-3)-beta-d-glucan (BG), galactomannan (GM), bis methyl-gliotoxin and urinary d-arabinitol/l-arabinitol ratio. In all, 13 cases with proven or probable invasive fungal disease (IFD) were identified. The sensitivity of BG and GM at the time of diagnosis (TOD) was low, but within 2 weeks from the TOD the sensitivity of BG was 92%. BG >800 pg/mL was highly specific for IFD. At a pre-test probability of 12%, both BG and GM had negative predictive values (NPV) >0.9 but low positive predictive values (PPV). In a subgroup analysis of patients with clinically suspected IFD (pre-test probability of 35%), the NPV was lower, but the PPV for BG was 0.86 at cut-off 160 pg/mL. Among IFD patients, 91% had patterns of consecutively positive and increasing BG levels. Bis-methyl-gliotoxin was undetectable in 15 patients with proven, probable and possible IA. To conclude, BG was the superior fungal marker for IFD diagnosis. Quantification above the limit of detection and graphical evaluation of the pattern of dynamics are warranted in the interpretation of BG results.

AB - Recombinant protein expression systems that produce high yields of pure proteins and multi-protein complexes are essential to meet the needs of biologists, biochemists, and structural biologists using X-ray crystallography and cryo electron microscopy. An ideal expression system for recombinant human proteins is cultured human cells where the correct translation and chaperone machinery are present. However, compared to bacterial expression systems, human cell cultures present several technical challenges to their use as an expression system. We developed a method that utilizes a YFP fusion-tag to generate recombinant proteins using suspension-cultured HEK293F cells. YFP is a dual-function tag that enables direct visualization and fluorescence-based selection of high expressing clones for and rapid purification using a high-stringency, high-affinity anti GFP/YFP nanobody support. We demonstrate the utility of this system by expressing two large human proteins, TOP2alpha (340 KDa dimer) and a TOP2beta catalytic core (260 KDa dimer). This robustly and reproducibly yields >10 mg/L liter of cell culture using transient expression or 2.5 mg/L using stable expression.

Research on new intrinsic self-healing cementitious materials with biomimetic features is on the forefront of material science, which provides a promising way to construct resilient and sustainable concrete infrastructures. Here, the current advances in the development of the intrinsic healing cementitious materials are described, and a new definition of intrinsic self healing discussed. The methods to assess the efficiency of different healing mechanisms are briefly summarized. The critical insights are emphasized to guide the future research on the development of new self-healing cementitious materials. PMID- 29577478 TI - Uptake of the Victorian Government school and early childhood service health promotion framework in the City of Greater Geelong according to area-level socioeconomic position. AB - ISSUE ADDRESSED: Whole-of-setting initiatives have been recommended as an equitable approach to health promotion. However, there has been little analysis of differences in uptake of such approaches according to indicators of socioeconomic position. In Victoria, Australia, the Achievement Program is a state government health promotion initiative that uses a whole-of-setting approach in early childhood services, schools and workplaces. We conducted an exploratory comparison of uptake of and progression through the programme by schools and early childhood services in one local area, according to area-level socioeconomic position. METHODS: Approximately 3 years after programme initiation, we linked data on the progress of 89 early childhood services and 67 primary schools to an area-level index of relative socioeconomic disadvantage. We compared uptake of and progression through the programme by setting (service or school) and quartiles of socioeconomic position. RESULTS: About 89% of early childhood services and 70% of primary schools had registered for the programme, with 18% and 15%, respectively, attaining the goal of completing the final stage. A greater proportion of settings in areas in the most disadvantaged quartile had registered for the programme and completed the final stage of the programme, compared with settings in areas in the least disadvantaged quartile. However, variation by socioeconomic position was not linear across quartiles. CONCLUSION: The Achievement Program did not appear to be inequitable in its uptake. Research into uptake in other local areas and outcomes achieved would be beneficial. SO WHAT?: This demonstrates that whole-of-setting approaches can potentially be an equity-enhancing approach to health promotion. PMID- 29577479 TI - Alcohol and injury risk at a Western Australian school Leavers Festival. AB - BACKGROUND: Leavers Festivals have become an institution for Australian youth to celebrate the completion of secondary school. Reported hazardous consumption of alcohol by leavers has focused concern on risk-taking behaviour. In response to this, campaigns such as "Don't Drink and Drown" have targeted youth to reduce alcohol consumption during aquatic activities. This research investigated intended and actual alcohol consumption, particularly during aquatic activities at a Leavers Festival located in the coastal town of Dunsborough, southern Western Australia. METHOD: In November 2016, 549 leavers aged 17 or 18 years completed a paper-based survey over a four-day period during the Festival. RESULTS: Overall, 90% of leavers reported intending to drink during the Festival, with expected average daily consumption being seven to nine standard drinks; reported daily consumption was five to six standard drinks (P < 0.001). Of the 29% of leavers who consumed alcohol around water during Leavers, 47% had done so while swimming. About 91% were aware of the campaign "Don't Drink and Drown." CONCLUSION: Awareness of the "Don't Drink and Drown" campaign and knowledge of risks associated with alcohol consumption and swimming were relatively high. Intention and actual consumption of alcohol did not correlate, with daily consumption less than anticipated. SO WHAT: Leavers appear to have a reasonable level of awareness and knowledge of the risks associated with alcohol consumption and aquatic activities, which may reflect the impact of education campaigns. However, this knowledge is not always translated into nonrisky aquatic behaviour. PMID- 29577477 TI - Neutrophil-Based Drug Delivery Systems. AB - White blood cells (WBCs) are a major component of immunity in response to pathogen invasion. Neutrophils are the most abundant WBCs in humans, playing a central role in acute inflammation induced by pathogens. Adhesion to vasculature and tissue infiltration of neutrophils are key processes in acute inflammation. Many inflammatory/autoimmune disorders and cancer therapies have been found to be involved in activation and tissue infiltration of neutrophils. A promising strategy to develop novel targeted drug delivery systems is the targeting and exploitation of activated neutrophils. Herein, a new drug delivery platform based on neutrophils is reviewed. There are two types of drug delivery systems: neutrophils as carriers and neutrophil-membrane-derived nanovesicles. It is discussed how nanoparticles hijack neutrophils in vivo to deliver therapeutics across blood vessel barriers and how neutrophil-membrane-derived nanovesicles target inflamed vasculature. Finally, the potential applications of neutrophil based drug delivery systems in treating inflammation and cancers are presented.

AB - Puberty is initiated by increased pulsatile gonadotropin-releasing hormone (GnRH) release from the hypothalamus. Epigenetic repression is thought to play a crucial role in the initiation of puberty, although the existence of analogous changes in methylation patterns across species is unclear. We analysed mRNA expression of DNA methyltransferases (DNMTs) and methyl-binding proteins (MBPs) in goats and rats by quantitative real-time PCR (qRT-PCR). DNA methylation profiles of hypothalamic were determined at the pre-pubertal and pubertal stages by bisulphite sequencing. In this study, expression of DNMTs and MBPs mRNA showed different patterns in goats and rats. Global methylation variation was low in goats and rats, and the profile remained stable during puberty. Gene ontology (GO) and Kyoto Encyclopedia of Gene and Genomes (KEGG) pathway analysis revealed the involvement of 62 pathways in puberty in goats and rats including reproduction, type I diabetes mellitus and GnRH signalling pathways and found that Edn3, PTPRN2 and GRID1 showed different methylation patterns during puberty in goats and rats and similar variation patterns for Edn3 and PTPRN2 were showed. These indicated that Edn3 and PTPRN2 would play a role in the timing of puberty. This study provides evidence of the epigenetic control of puberty. PMID- 29577481 TI - Genetic architecture of traits associated with reproductive barriers in Silene: Coupling, sex chromosomes and variation. AB - The evolution of reproductive barriers and their underlying genetic architecture is of central importance for the formation of new species. Reproductive barriers can be controlled either by few large-effect loci suggesting strong selection on key traits, or by many small-effect loci, consistent with gradual divergence or with selection on polygenic or multiple traits. Genetic coupling between reproductive barrier loci further promotes divergence, particularly divergence with ongoing gene flow. In this study, we investigated the genetic architectures of ten morphological, phenological and life history traits associated with reproductive barriers between the hybridizing sister species Silene dioica and S. latifolia; both are dioecious with XY-sex determination. We used quantitative trait locus (QTL) mapping in two reciprocal F2 crosses. One to six QTLs per trait, including nine major QTLs (PVE > 20%), were detected on 11 of the 12 linkage groups. We found strong evidence for coupling of QTLs for uncorrelated traits and for an important role of sex chromosomes in the genetic architectures of reproductive barrier traits. Unexpectedly, QTLs detected in the two F2 crosses differed largely, despite limited phenotypic differences between them and sufficient statistical power. The widely dispersed genetic architectures of traits associated with reproductive barriers suggest gradual divergence or multifarious selection. Coupling of the underlying QTLs likely promoted divergence with gene flow in this system. The low congruence of QTLs between the two crosses further points to variable and possibly redundant genetic architectures of traits associated with reproductive barriers, with important implications for the evolutionary dynamics of divergence and speciation. PMID- 29577482 TI - Testing Wallace's intuition: water type, reproductive isolation and divergence in an Amazonian fish. AB - Alfred Russel Wallace proposed classifying Amazon rivers based on their colour and clarity: white, black and clear water. Wallace also proposed that black waters could mediate diversification and yield distinct fish species. Here, we bring evidence of speciation mediated by water type in the sailfin tetra (Crenuchus spilurus), a fish whose range encompasses rivers of very distinct hydrochemical conditions. Distribution of the two main lineages concords with Wallace's water types: one restricted to the acidic and nutrient-poor waters of the Negro River (herein Rio Negro lineage) and a second widespread throughout the remaining of the species' distribution (herein Amazonas lineage). These lineages occur over a very broad geographical range, suggesting that despite occurring in regions separated by thousands of kilometres, individuals of the distinct lineages fail to occupy each other's habitats, hundreds of metres apart and not separated by physical barrier. Reproductive isolation was assessed in isolated pairs exposed to black-water conditions. All pairs with at least one individual of the lineage not native to black waters showed significantly lower spawning success, suggesting that the water type affected the fitness and contributed to reproductive isolation. Our results endorse Wallace's intuition and highlight the importance of ecological factors in shaping diversity of the Amazon fish fauna.

PMID- 29577487 TI - The effectiveness of contingency management in the treatment of patients with anorexia nervosa: A systematic review. AB - Contingency management in stipulating weight gain is routinely used in the treatment of anorexia nervosa, however, empirical investigations concerning its effectiveness have been scarce. This systematic review was conducted according to the PRISMA statement. Of N = 973 hits, 42 full-texts were included in the qualitative synthesis (11 theoretical texts, 19 case reports, 12 descriptive, cohort, and controlled trials). A central topic in the included publications concerns the enhancement of patients' autonomy through participation in the contingency management process. This heightened autonomy is achieved by using contingency contracts. Positive short-term effects on weight gain were shown, whereas follow-up results were heterogeneous. Although contingency contracts are widely used in clinical practice, our systematic review shows that empirical evidence on underlying mechanisms and efficacy is still scarce. Using an explicit treatment contract can enhance patients' motivation, compliance, and autonomy. Clinical practice should see further development including innovative motivation enhancing and conflict dissolving techniques in addressing the pronounced ambivalence often shown by patients with anorexia nervosa. PMID- 29577488 TI - Cytomorphology and sonographic features of ectopic thymic tissue diagnosed in paediatric FNA biopsies. AB - INTRODUCTION: Ectopic thymic tissue can arise as an asymptomatic neck mass, which may be detected on imaging studies. The aim of this study was to determine the incidence of ectopic thymic tissue in paediatric FNAs and to the correlate clinical, radiological and cytomorphological findings. METHODS: FNAs in children with neck and mediastinal lesions performed between January 2012 and July 2016 were reviewed for cases of ectopic thymus. These were then evaluated and correlated with the cytology findings. RESULTS: Of 739 FNAs, 13 (1.8%) cases from 11 patients showed ectopic thymic tissue. The targeted lesions were in the thyroid (n = 7), submandibular region (n = 1), superior mediastinum (n = 1) and paratracheal region (n = 1). The most common indication was for microcalcifications concerning for papillary thyroid carcinoma on ultrasound (n = 6). Imaging findings included fusiform lesions with linear and punctuate bright echoes. The cytology evaluation showed small lymphocytes with discohesive epithelioid cells in most cases, and proteinaceous fluid in the cystic case. There were rare macrophages and Hassall's corpuscles. Flow cytometry and/or immunostains were performed in all cases, supporting thymic origin. CONCLUSION: Ectopic thymic tissue is rarely present as a neck mass or thyroid nodule on FNA biopsy. The ultrasound imaging findings reveal a well-defined fusiform lesion with punctate bright echoes that could be misinterpreted as papillary thyroid carcinoma. The aspirates show a small lymphoid population, immunophenotypically compatible with thymic T-cells, in addition to scattered epithelial cells. Therefore, knowledge of the typical ultrasonographic and cytopathological features can help make a definitive diagnosis and avoid more invasive procedures in paediatric patients. PMID- 29577489 TI - Alternative evaluation metrics for risk adjustment methods. AB - Risk adjustment is instituted to counter risk selection by accurately equating payments with expected expenditures. Traditional risk-adjustment methods are designed to estimate accurate payments at the group level. However, this generates residual risks at the individual level, especially for high-expenditure individuals, thereby inducing health plans to avoid those with high residual risks. To identify an optimal risk-adjustment method, we perform a comprehensive comparison of prediction accuracies at the group level, at the tail distributions, and at the individual level across 19 estimators: 9 parametric regression, 7 machine learning, and 3 distributional estimators. Using the 2013 2014 MarketScan database, we find that no one estimator performs best in all prediction accuracies. Generally, machine learning and distribution-based estimators achieve higher group-level prediction accuracy than parametric regression estimators. However, parametric regression estimators show higher tail distribution prediction accuracy and individual-level prediction accuracy, especially at the tails of the distribution. This suggests that there is a trade off in selecting an appropriate risk-adjustment method between estimating accurate payments at the group level and lower residual risks at the individual level. Our results indicate that an optimal method cannot be determined solely on the basis of statistical metrics but rather needs to account for simulating plans' risk selective behaviors. PMID- 29577490 TI - A Qualitative Analysis of Patients' Perceptions of Shared Decision Making in the Emergency Department: "Let Me Know I Have a Choice". AB - BACKGROUND AND OBJECTIVES: Despite increasing attention to the use of shared decision making (SDM) in the emergency department (ED), little is known about ED patients' perspectives regarding this practice. We sought to explore the use of SDM from the perspectives of ED patients, focusing on what affects patients' desired level of involvement and what barriers and facilitators patients find most relevant to their experience. METHODS: We conducted semistructured interviews with a purposive sample of ED patients or their proxies at two sites. An interview guide was developed from existing literature and expert consensus and based on a framework underscoring the importance of both knowledge and power. Interviews were recorded, transcribed, and analyzed in an iterative process by a three-person coding team. Emergent themes were identified, discussed, and organized. RESULTS: Twenty-nine patients and proxies participated. The mean age of participants was 56 years (range, 20 to 89 years), and 13 were female. Participants were diverse in regard to race/ethnicity, education, number of previous ED visits, and presence of chronic conditions. All participants wanted some degree of involvement in decision making. Participants who made statements suggesting high self-efficacy and those who expressed mistrust of the health care system or previous negative experiences wanted a greater degree of involvement. Facilitators to involvement included familiarity with the decision at hand, physicians' good communication skills, and clearly delineated options. Some participants felt that their own relative lack of knowledge, compared to that of the physicians, made their involvement inappropriate or unwanted. Many participants had no expectation for SDM and although they did want involvement when asked explicitly, they were otherwise likely to defer to physicians without discussion. Many did not recognize opportunities for SDM in their clinical care. CONCLUSIONS: This exploration of ED patients' perceptions of SDM suggests that most patients want some degree of involvement in medical decision making but more proactive engagement of patients by clinicians is often needed. Further research should examine these issues in a larger and more representative population. PMID- 29577491 TI - A Free Silanide from Nucleophilic Substitution at Silicon(II). AB - A computationally guided synthetic route to a free silanide derived from tris(3 methylindol-2-yl)methane ([(tmim)Si]- ) through nucleophilic substitution on the SiII precursor (Idipp)SiCl2 is reported (Idipp=2,3-dihydro-1,3-bis(2,6 diisopropylphenyl)-1H-imidazol-2-ylidene). This approach circumvents the need for strained tetrahedral silanes as synthetic intermediates. Computational investigations show that the electron-donating properties of [(tmim)Si]- are close to those of PMe3. Experimentally, the [(tmim)Si]- anion is shown to undergo clean complexation to the base metal salts CuCl and FeCl2 , demonstrating the potential utility as a supporting ligand. PMID- 29577492 TI - Nitric oxide synthase and oxidative-nitrosative stress play a key role in placental infection by Trypanosoma cruzi. AB - PROBLEM: The innate immune response of the placenta may participate in the congenital transmission of Chagas disease through releasing reactive oxygen and nitrogen intermediates. METHOD OF STUDY: Placental explants were cultured with 1 * 106 and 1 * 105 trypomastigotes of Tulahuen and Lucky strains and controls without parasites, and with the addition of nitric oxide synthase inhibitor Nomega-Nitro-l-arginine methyl ester (l-NAME) and N-acetyl cysteine (NAC) as the reactive oxygen species (ROS) scavenger. Detachment of the syncytiotrophoblast (STB) was examined by histological analysis, and the nitric oxide synthase, endothelial (eNOS), and nitrotyrosine expressions were analyzed by immunohistochemistry, as well as the human chorionic gonadotrophin (hCG) levels in the culture supernatant through ELISA assays. Parasite load with qPCR using Taqman primers was quantified. RESULTS: The higher number of T. cruzi (106 ) increased placental infection, eNOS expression, nitrosative stress, and STB detachment, with the placental barrier being injured by oxidative stress. CONCLUSION: The higher number of parasites caused deleterious consequences to the placental barrier, and the inhibitors (l-NAME and NAC) prevented the damage caused by trypomastigotes in placental villi but not that of the infection. Moreover, trophoblast eNOS played a key role in placental infection with the highest inoculum of Lucky, demonstrating the importance of the enzyme and nitrosative-oxidative stress in Chagas congenital transmission. PMID- 29577493 TI - 2SLS versus 2SRI: Appropriate methods for rare outcomes and/or rare exposures. AB - This study used Monte Carlo simulations to examine the ability of the two-stage least squares (2SLS) estimator and two-stage residual inclusion (2SRI) estimators with varying forms of residuals to estimate the local average and population average treatment effect parameters in models with binary outcome, endogenous binary treatment, and single binary instrument. The rarity of the outcome and the treatment was varied across simulation scenarios. Results showed that 2SLS generated consistent estimates of the local average treatment effects (LATE) and biased estimates of the average treatment effects (ATE) across all scenarios. 2SRI approaches, in general, produced biased estimates of both LATE and ATE under all scenarios. 2SRI using generalized residuals minimized the bias in ATE estimates. Use of 2SLS and 2SRI is illustrated in an empirical application estimating the effects of long-term care insurance on a variety of binary health care utilization outcomes among the near-elderly using the Health and Retirement Study. PMID- 29577494 TI - Placenta immune infiltrates and perinatal outcomes. AB - Pregnancy is a state of immunotolerance and loss of this immunotolerance may lead to fetal rejection, pregnancy complications, and neonatal complications. Immunobiology of pregnancy is complex and involves unique immune cell populations specific to pregnancy, changes in mucosal immune cells and peripheral immune system, and reciprocal adaptations between the mother and the fetus. The mechanisms required for sustaining a healthy feto-placental barrier and a healthy pregnancy such as activation of regulatory immune responses with a predominance of regulatory T cells lead to immune evasion and propagation of cancer. It is intriguing to note that the immune pathways which are effective in limiting or eliminating cancer form the very basis for loss of feto-maternal tolerance. In this article, we aim to compare and contrast immunobiology of healthy and pathological pregnancies mirroring with cancer immunobiology with a focus on immune checkpoint receptors. PMID- 29577495 TI - HCV genotype 4, 5 and 6: Distribution of viral subtypes and sustained virologic response rates in clinical trials of approved direct-acting antiviral regimens. AB - Multiple direct-acting antiviral (DAA)-based regimens are now available for all hepatitis C virus (HCV) genotypes (GTs). Because HCV GT 4, 5 and 6 are less common in the United States (US) and worldwide, relatively small numbers of participants with these GTs were evaluated in individual clinical trials. To provide a comprehensive description of subtype diversity and treatment outcomes in clinical trials for these less common GTs, we analysed data from 744 participants with HCV GT4 (n = 573), GT5 (n = 81), or GT6 (n = 90) across 18 clinical trials of DAA regimens. These data are from US New Drug Applications submitted between 2014 and 2017, and our analyses included only approved regimens. Excluding unresolved or mixed subtypes, the distribution of reported GT4 subtypes was 49% 4a, 31% 4d and 16% for one of 14 other subtypes. The distribution of GT6 subtypes was 39% 6a, 27% 6e, 8% 6 L and 23% for one of 11 other subtypes. Across approved regimens, sustained virologic response rates 12 weeks post-treatment (SVR12) for GT 4, 5 and 6 ranged from 91% to 100%, 93% to 97% and 96% to 100%, respectively. SVR12 by GT4 subtype ranged from 96% to 100% for 4a and 81% to 100% for 4d. Virologic failures occurred in GT 4a, 4b, 4d and 4r. For GT6, SVR12 was 100% for all subtypes except 6 L, for which 1 of 7 participants experienced virologic failure. To our knowledge, this is the largest compilation of HCV GT 4, 5 or 6 clinical trial data. These analyses may be useful for clinicians treating HCV GT 4, 5 or 6. PMID- 29577496 TI - Transcranial direct current stimulation for upper limb neuropathic pain: A double blind randomized controlled trial. AB - BACKGROUND: While promising, there are mixed findings for the efficacy of transcranial direct current stimulation (tDCS) for the management of chronic pain. The goal of this study was to evaluate the effect of anodal tDCS on pain and function in people with upper limb neuropathic pain. METHODS: The study was a double-blinded, randomized controlled trial. Thirty participants were randomly allocated into active and sham tDCS groups. Baseline assessments of pain and function, as well as quantitative sensory testing (QST) to probe the function of the nociceptive system, were undertaken prior to participants receiving 5 days of active or sham anodal tDCS (1 mA) over the primary motor cortex. The outcome measures were re-assessed 1, 3 and 8 weeks following the intervention. RESULTS: Group analyses revealed no significant improvement in pain, function, or QST measures over time in either group. However, there were significantly more individual responders (>=30% change in pain) in the active compared to the sham tDCS group at the final follow-up. In the active group, there was a significant correlation indicating those with higher baseline pain had greater pain relief. CONCLUSIONS: On group analyses, no evidence was provided that 1 mA tDCS is beneficial for people with upper limb neuropathic pain, although it may provide lasting pain relief for some individuals. SIGNIFICANCE: At the group level, we found no evidence that 5 days of active 1 mA tDCS is effective for people with upper limb neuropathic pain. However, there were more individual responders in the active tDCS group compared to sham, and those who responded early after treatment experienced sustained pain relief. PMID- 29577497 TI - Pliocene-Pleistocene ecological niche evolution shapes the phylogeography of a Mediterranean plant group. AB - Estimating species ability to adapt to environmental changes is crucial to understand their past and future response to climate change. The Mediterranean Basin has experienced remarkable climatic changes since the Miocene, which have greatly influenced the evolution of the Mediterranean flora. Here, we examine the evolutionary history and biogeographic patterns of two sedge sister species (Carex, Cyperaceae) restricted to the western Mediterranean Basin, but with Pliocene fossil record in central Europe. In particular, we estimated the evolution of climatic niches through time and its influence in lineage differentiation. We carried out a dated phylogenetic-phylogeographic study based on seven DNA regions (nDNA and ptDNA) and fingerprinting data (AFLPs), and modelled ecological niches and species distributions for the Pliocene, Pleistocene and present. Phylogenetic and divergence time analyses revealed that both species form a monophyletic lineage originated in the late Pliocene-early Pleistocene. We detected clear genetic differentiation between both species with distinct genetic clusters in disjunct areas, indicating the predominant role of geographic barriers limiting gene flow. We found a remarkable shift in the climatic requirements between Pliocene and extant populations, although the niche seems to have been relatively conserved since the Pleistocene split of both species. This study highlights how an integrative approach combining different data sources and analyses, including fossils, allows solid and robust inferences about the evolutionary history of a plant group since the Pliocene. PMID- 29577499 TI - Venous and autonomic function in formerly pre-eclamptic women and BMI-matched controls. AB - INTRODUCTION: Pre-pregnancy reduced plasma volume increases the risk on subsequent pre-eclamptic pregnancy. Reduced plasma volume is thought to reflect venous reserve capacity, especially when venous vasculature is constricted and sympathetic tone is elevated. As obesity might affect these variables and also relates to pre-eclampsia, increased body weight may underlie these observations. We hypothesized that the relationship between reduced venous reserve and preeclampsia is independent of body mass index (BMI). METHODS: We compared the non-pregnant venous reserve capacity in 30 formerly pre-eclamptic women, equally divided in 3 BMI-classes (BMI 19.5-24.9, BMI 25-29.9, BMI >=30) to 30 controls. Cases and controls were matched for BMI, age and parity. The venous reserve capacity was quantified by assessing plasma volume and venous compliance. The autonomic nervous system regulating the venous capacitance was evaluated with heart rate variability analysis in resting supine position and during positive head-up tilt (HUT). RESULTS: Formerly pre-eclamptic women had in supine position lower plasma volume than controls (1339 +/- 79 vs 1547 +/- 139 ml/m2 (p<0.001)), lower venous compliance (0.04 +/- 0.02 vs 0.07 +/- 0.02 ml/dl/mmHg (p<0.001)), higher sympathetic tone (1.9 +/- 0.1 vs 1.2 +/- 0.7 mmHg2 (p=0.002)) and lower baroreceptor sensitivity (8.7 +/- 3.8 vs 19.0 +/- 1.7 ms/mmHg (p<0.001)). During HUT, women with a history of preeclampsia have less modulatory capacity over venous compliance and baroreceptor sensitivity, while heart rate and sympathetic tone remain consistently higher. CONCLUSION: Women with a history of pre eclampsia have, compared to BMI-matched controls, reduced venous reserve capacity. This is reflected by lower plasma volume and venous compliance, the autonomic balance is shifted towards sympathetic dominance and lower baroreceptor sensitivity. This suggests that not BMI, but underlying reduced venous reserve relates to pre-eclampsia. PMID- 29577498 TI - Evaluation of multiple alternative instrument platforms for targeted and non targeted dioxin and furan analysis. AB - The use of gas chromatography coupled to high-resolution magnetic sector mass spectrometers (GC-HRMS) is well established for dioxin and furan analysis. However, the use of gas chromatography coupled to triple quadrupole (MS/MS) and time of flight (TOF) mass spectrometers with atmospheric pressure ionization (API) and traditional electron ionization (EI) for dioxin and furan analysis is emerging as a viable alternative to GC-HRMS screening. These instruments offer greater versatility in the lab for a wider range of compound identification and quantification as well as improved ease of operation. The instruments utilized in this study included 2 API-MS/MS, 1 traditional EI-MS/MS, an API-quadrupole time of flight mass spectrometer (API-QTOF), and a EI-high-resolution TOF (EI-HRTOF). This study compared these 5 instruments to a GC-HRMS using method detection limit (MDLs) samples for dioxin and furan analysis. Each instrument demonstrated acceptable MDL values for the 17 chlorinated dioxin and furans studied. The API MS/MS instruments provide the greatest overall improvement in MDL value over the GC-HRMS with a 1.5 to 2-fold improvement. The API-QTOF and EI-TOF demonstrate slight increases in MDL value as compared with the GC-HRMS with a 1.5-fold increase. The 5 instruments studied all demonstrate acceptable MDL values with no MDL for a single congener greater than 5 times that for the GC-HRMS. All 5 instruments offer a viable alternative to GC-HRMS for the analysis of dioxins and furans and should be considered when developing new validated methodologies. PMID- 29577500 TI - Hybridization could be a common phenomenon within the highly diverse lizard genus Liolaemus. AB - Hybridization is likely to occur more often between closely related taxa that have had insufficient time to diverge to the point of reproductive incompatibility; hybridization between deeply divergent lineages is rare. In squamate reptiles, hybridization has been proposed as a possible explanation for the extensive paraphyly observed in mitochondrial gene trees in several species complexes of the South American lizard genus Liolaemus. One of the best documented cases is within the L. boulengeri and L. rothi complexes, which diverged ~5.5 million years ago. Here, we describe a comprehensive study for approaching the hybridization hypothesis between these lizard species complexes. We explored the level of gene tree discordance using the novel 'extra lineage contribution' statistics (XLC, presented in this study) that quantifies the level of gene tree discordance contribution per individual within a species. We included molecular data (12 nuclear and two mitochondrial genes) from 127 individuals, and results of a coalescent model-based analysis show that the most likely explanation for the gene tree-species tree discordance is interspecific hybridization. Our best-supported hypothesis suggests current and past hybridization between L. rothi (rothi complex) and L. tehuelche (boulengeri complex), and independently between L. rothi and L. boulengeri and L. telsen (boulengeri complex). The hybrid descendants are characterized by intermediate phenotypes between the parental species, but are more similar to L. rothi in body size. We discuss the possible role of hybridization in Liolaemus evolution. PMID- 29577501 TI - The ART of brain expression. AB - When trying to find a mate, one might think about using a dating app. Imagine that someone else has installed the same app and tries to access the same potential mates that you have chosen, and that this someone uses false facts about himself/herself to increase the chance of dating someone before you or anyone else with honest status information does. Sounds familiar? It actually is, and in no way is such comportment restricted to human courtship behaviour. Alternative reproductive tactics (ARTs) are widespread in the animal kingdom. In this issue of Molecular Ecology, Cardoso, Goncalves, Goesmann, Canario, and Oliveira () investigate plastic ARTs of the peacock blenny (Salaria pavo), in which males occur in three morphs: nestholders, sneakers and transitionals between the two former. They apply transcriptome sequencing to answer the question how brain gene expression contributes to sex role-specific behaviour and to intersex phenotypes. PMID- 29577502 TI - Do parasites and antioxidant availability affect begging behaviour, growth rate and resistance to oxidative stress? AB - Early-life trade-offs faced by developing offspring can have long-term consequences for their future fitness. Young offspring use begging displays to solicit resources from their parents and have been selected to grow fast to maximize survival. However, growth and begging behaviour are generally traded off against self-maintenance. Oxidative stress, a physiological mediator of life history trade-offs, may play a major role in this trade-off by constraining, or being costly to, growth and begging behaviour. Yet, despite implications for the evolution of life-history strategies and parent-offspring conflicts, the interplay between growth, begging behaviour and resistance to oxidative stress remains to be investigated. We experimentally challenged wild great tit (Parus major) offspring by infesting nests with a common ectoparasite, the hen flea (Ceratophyllus gallinae), and simultaneously tested for compensating effects of increased vitamin E availability, a common dietary antioxidant. We further quantified the experimental treatment effects on offspring growth, begging intensity and oxidative stress. Flea-infested nestlings of both sexes showed reduced body mass during the first half of the nestling phase, but this effect vanished short before fledging. Begging intensity and oxidative stress of both sexes were unaffected by both experimental treatments. Feeding rates were not affected by the experimental treatments, but parents of flea-infested nests fed nestlings with a higher proportion of caterpillars, the main source of antioxidants. Additionally, female nestlings begged significantly less than males in control nests, whereas both sexes begged at similar rates in vitamin E supplemented nests. Our study shows that a parasite exposure does not necessarily affect oxidative stress levels or begging intensity, but suggests that parents can compensate for negative effects of parasitism by modifying food composition. Furthermore, our results indicate that the begging capacity of the less competitive sex is constrained by antioxidant availability.

AB - The present study aimed to examine the modality and redundancy effects in multimedia learning in children with dyslexia in order to find out whether their learning benefits from written and/or spoken text with pictures. We compared study time and knowledge gain in 26 11-year-old children with dyslexia and 38 typically reading peers in a within-subjects design. All children were presented with a series of user-paced multimedia lessons in 3 conditions: pictorial information presented with (a) written text, (b) audio, or (c) combined text and audio. We also examined whether children's learning outcomes were related to their working memory. With respect to study time, we found modality and reversed redundancy effects. Children with dyslexia spent more time learning in the text condition, compared with the audio condition and the combined text-and-audio condition. Regarding knowledge gain, no modality or redundancy effects were evidenced. Although the groups differed on working memory, it did not influence the modality or redundancy effect on study time or knowledge gain. In multimedia learning, it thus is more efficient to provide children with dyslexia with audio or with auditory support. PMID- 29577505 TI - Efficacy and safety of bilateral thoracic paravertebral blocks in outpatient breast surgery. AB - Unilateral thoracic paravertebral blocks (TPVBs) have demonstrated reliable intraoperative analgesia, low postoperative pain scores, and an opioid-sparing effect in breast cancer surgery. However, secondary to the perceived risk of complications, bilateral TPVB have been less well accepted and are less frequently used. The purpose of this study was to evaluate the feasibility of using bilateral TPVBs in outpatient surgery for patients undergoing bilateral mastectomy with immediate implant-based reconstruction. Electronic medical records were retrospectively reviewed for patients receiving bilateral TPVBs for bilateral mastectomy with immediate implant-based reconstruction performed by a single surgeon from September 2012 to September 2015. Records were reviewed for incidence of complications, time to discharge, and incidence of unplanned admission or readmission. Clopper-Pearson method for binomial distribution was used to calculate confidence intervals for proportions. Forty-five patients undergoing bilateral mastectomy with immediate reconstruction received bilateral TPVBs. There were 4 TPVB-related complications, all of which were symptomatic hypotension or bradycardia (9%; 95% CI, 2%-21%). There was no incidence of symptomatic pneumothorax. Mean time to discharge readiness from the postanesthesia care unit (PACU) was 1.9 hours (SD = 1.0). Overall, 91% (n = 29) of the 32 patients scheduled for day surgery were discharged home as planned. Mean time from entry to PACU to home discharge for day surgery patients (n = 32) and planned admissions (n = 13) was 5.9 hours (SD = 4.3) and 16.3 hours (SD = 3.6), respectively. There was no incidence of readmission following discharge. Bilateral TPVBs can safely facilitate day surgery in carefully selected patients undergoing bilateral mastectomy with immediate implant-based reconstruction. PMID- 29577506 TI - The role of epistatic interactions underpinning resistance to parasitic Varroa mites in haploid honey bee (Apis mellifera) drones. AB - The Red Queen hypothesis predicts that host-parasite coevolutionary dynamics can select for host resistance through increased genetic diversity, recombination and evolutionary rates. However, in haplodiploid organisms such as the honeybee (Apis mellifera), models suggest the selective pressure is weaker than in diploids. Haplodiploid sex determination, found in A. mellifera, can allow deleterious recessive alleles to persist in the population through the diploid sex with negative effects predominantly expressed in the haploid sex. To overcome these negative effects in haploid genomes, epistatic interactions have been hypothesized to play an important role. Here, we use the interaction between A. mellifera and the parasitic mite Varroa destructor to test epistasis in the expression of resistance, through the inhibition of parasite reproduction, in haploid drones. We find novel loci on three chromosomes which explain over 45% of the resistance phenotype. Two of these loci interact only additively, suggesting their expression is independent of each other, but both loci interact epistatically with the third locus. With drone offspring inheriting only one copy of the queen's chromosomes, the drones will only possess one of two queen alleles throughout the years-long lifetime of the honeybee colony. Varroa, in comparison, completes its highly inbred reproductive cycle in a matter of weeks, allowing it to rapidly evolve resistance. Faced with the rapidly evolving Varroa, a diversity of pathways and epistatic interactions for the inhibition of Varroa reproduction could therefore provide a selective advantage to the high levels of recombination seen in A. mellifera. This allows for the remixing of phenotypes despite a fixed queen genotype.

AB - ISSUE ADDRESSED: Exposure to advertising for unhealthy food, alcohol and gambling has been shown to influence children and adolescents' behaviours and attitudes. This exploratory study aimed to assess the volume and type of unhealthy bus shelter advertisements near schools in five local government areas in Perth, Western Australia and to monitor whether the volume of unhealthy advertisements varied seasonally. METHODS: The 29 local governments in the Perth metropolitan region were contacted seeking information regarding the locations of bus shelters featuring advertisements in their local government area. Five local governments provided sufficient information for an audit of the bus shelter advertisements in their area to be conducted. Every bus shelter within 500 m of a school was photographed and the type of advertisement recorded. The advertisements in the food, non-alcoholic beverage, alcohol, or gambling categories were then classified as being healthy, moderate, or unhealthy. This process was carried out in June, September, December 2016, and March 2017 to ascertain whether the type of advertisements displayed changed depending on the season. RESULTS: Of the 293 advertisements recorded over the four audits, 31% featured unhealthy products, 3% moderate, and <1% healthy. Only two of the 293 advertisements were classified as being healthy. Seasonal variation in the volume of unhealthy advertisements was not identified. SO WHAT?: Western Australian school students are regularly exposed to unhealthy bus shelter advertisements. Stricter regulation of outdoor advertising is needed to ensure that young people are protected from the influence of unhealthy industries.

AB - Although neurogastroenterology and motility (NGM) disorders are some of the most frequent disorders encountered by practicing gastroenterologists, a structured competency-based training curriculum developed by NGM experts is lacking. The American Neurogastroenterology and Motility Society (ANMS) and the European Society of Neurogastroenterology and Motility (ESNM) jointly evaluated the components of NGM training in North America and Europe. Eleven training domains were identified within NGM, consisting of functional gastrointestinal disorders, visceral hypersensitivity and pain pathways, motor disorders within anatomic areas (esophagus, stomach, small bowel and colon, anorectum), mucosal disorders (gastro-esophageal reflux disease, other mucosal disorders), consequences of systemic disease, consequences of therapy (surgery, endoscopic intervention, medications, other therapy), and transition of pediatric patients into adult practice. A 3-tiered training curriculum covering these domains is proposed here and endorsed by all NGM societies. Tier 1 NGM knowledge and training is expected of all gastroenterology trainees and practicing gastroenterologists. Tier 2 knowledge and training is appropriate for trainees who anticipate NGM disorder management and NGM function test interpretation being an important part of their careers, which may require competency assessment and credentialing of test interpretation skills. Tier 3 knowledge and training is undertaken by trainees interested in a dedicated NGM career and may be restricted to specific domains within the broad NGM field. The joint ANMS and ESNM task force anticipates that the NGM curriculum will streamline NGM training in North America and Europe and will lead to better identification of centers of excellence where Tier 2 and Tier 3 training can be accomplished. PMID- 29577509 TI - Comorbidity between pain and mental illness - Evidence of a bidirectional relationship. AB - BACKGROUND: Pain from various locations in the body and mental illness are common and the comorbidity between the two is well-known although the temporal relationship remains to be determined. Our aim was to follow patients over time to study if pain (here dorsalgia/abdominal pain) or fibromyalgia lead to an increased risk of developing mental illness (here depression/anxiety) and/or the reverse, that is whether patients with mental illness have an increased risk to develop pain or fibromyalgia, compared to the rest of the population. METHODS: This prospective cohort study used the Skane Healthcare Register, covering all care in the region of Skane, southern Sweden (population ~1.3 million). The cohort included healthcare consultations in primary care, outpatient specialized care and inpatient care between 2007 and 2016 for all patients without prior registered diagnosis of mental illness or pain, aged 18 or older (n = 504,365). RESULTS: The incidence rate ratio (IRR) for developing mental illness after pain was 2.18 (95% CI = 2.14-2.22) compared to without pain. IRR for developing pain after mental illness was 2.02 (95% CI = 1.98-2.06) compared to without mental illness. Corresponding IRR for developing mental illness after fibromyalgia was 4.05 (95% CI = 3.58-4.59) and for developing fibromyalgia after mental illness 5.54 (95% CI = 4.99-6.16). CONCLUSIONS: This study shows a bidirectional influence of similar magnitude of pain and mental illness, respectively. In monitoring patients with pain or mental illness, a focus on both conditions is thus important to develop appropriate, targeted interventions and may increase the likelihood of improved outcomes. SIGNIFICANCE: We followed a population-based cohort over a period of 10 years, including incident cases of both exposure and outcome and found a bidirectional relationship between pain and mental illness. Clinicians need to pay attention on both conditions, in patients seeking care due to mental illness or pain. PMID- 29577510 TI - Successful treatment with steroid and cyclosporine A in a patient with immunoglobulin A-proliferative glomerulonephritis with monoclonal immunoglobulin deposits. AB - We report a case of glomerulonephritis with monoclonal immunoglobulin (Ig) A deposits as a form of monoclonal gammopathy of renal significance (MGRS) caused by monoclonal immunoglobulins without blood disorders in a 41-year-old woman. She developed lower leg oedema and was hospitalized because of nephrotic syndrome. Serum and urine were negative for M protein, and the free light chain kappa/lambda ratio was within the normal range. Renal histopathological findings included mesangial proliferation, endocapillary cell proliferation, and a double contour appearance of the capillary walls. Immunofluorescent staining indicated IgA and C3 deposits on the mesangium and capillary walls. Only lambda chain and IgA1 deposits were noted. Fine granular sub-endothelial deposits with no specific structure were observed under electron microscopy. The patient was diagnosed with IgA-proliferative glomerulonephritis with monoclonal immunoglobulin deposits (IgA PGNMID). The patient had decreased urine protein and sediment erythrocytes after she underwent two rounds of steroid pulse therapy and oral steroid therapy, but proteinuria and haematuria still remained. Four months later, the patient was administered 50 mg/day cyclosporine (CsA), and proteinuria and haematuria dramatically decreased. Only few case reports have been published on IgA-PGNMID. This case is rare in that the patient achieved successful treatment using a combination of steroids and CsA. PMID- 29577511 TI - Association between interleukin 8-receptor gene (CXCR1 and CXCR2) polymorphisms and urinary tract infection: evidence from 4097 subjects. AB - The aim of this study was to determine whether a correlation exists between interleukin-8 receptor polymorphisms and urinary tract infection (UTI) susceptibility. We systematically searched electronic databases including PubMed, Embase, China National Knowledge Infrastructure, and Web of Science up to November 5, 2017 to select appropriate studies that focused on C-X-C chemokine receptor type 1 and/or 2 (CXCR1, CXCR2) polymorphisms with susceptibility to UTI. Eight case-control studies including 2085 patients with UTI and 2012 controls were enrolled in this study. Seven studies of CXCR1 rs2234671 and two studies of rs3138086 were included in the meta-analyses. Pooled odds ratio (OR) and corresponding 95% confidence interval (CI) were synthesized using fixed-effects or random-effects model according to heterogeneity. No significant correlations were found between CXCR1 rs2234671 and rs3138086 polymorphisms and UTI susceptibility. However, subgroup analysis showed that rs2234671 was associated with an increased risk of UTI under allelic comparisons (C vs. G, OR = 1.95, 95% CI = 1.07-3.55), heterozygous model (GC vs. GG, OR = 1.93, 95% CI = 1.06-3.50), and dominant model (GC+CC vs. GG, OR = 1.98, 95% CI = 1.07-3.69) in children, especially in pediatric patients with acute pyelonephritis (allelic, OR = 2.43, 95% CI = 1.28-4.60; heterozygous, OR = 2.40, 95% CI = 1.24-4.62; dominant, OR = 2.48, 95% CI = 1.26-4.88). Furthermore, these results remained the same after eliminating paediatric patients with vesicoureteral reflux. CXCR1 rs2234671 polymorphism might be associated with an increased risk of UTI in children. PMID- 29577512 TI - Cognitive remediation therapy (CRT) in a specialist inpatient eating disorder service for children and adolescents: CAN-CRT study protocol for a pilot randomised controlled trial. AB - INTRODUCTION: Research on treatments for young people (YP) with anorexia nervosa (AN) is scarce. Evidence supports the use of cognitive remediation therapy (CRT) to improve central coherence and set-shifting, inefficiencies that can negatively impact on prognosis. OBJECTIVE: The study aims to evaluate the feasibility of individual CRT in an inpatient setting for YP aged 10-18 years with AN and to qualitatively examine YP's and their parents experiences. METHOD: In a single centre, pilot, randomised controlled trial, 80 patients aged 10-18 years with AN will be randomly allocated to the immediate or delayed CRT group, in addition to standard treatment. A repeated measures design will be conducted across 3 time points. DISCUSSION: The data will provide evidence regarding the feasibility of individual CRT in YP with AN, informing directions of further development of CRT. The study is in preparation for a definitive randomised controlled trial. The aim of this manuscript is to describe the study protocol. PMID- 29577513 TI - Placental immune state shifts with gestational age. AB - PROBLEM: Placental immunologic functions are implicated in both the maintenance of a healthy pregnancy and the pathogenesis of obstetric complications. Immune populations at the maternal-fetal interface are hypothesized to support fetomaternal tolerance, defend the fetus from infection, and contribute to labor initiation. Despite the many potential roles of placental immune cells in normal and abnormal pregnancy, little is known about placental immune population dynamics over gestation, particularly near parturition. METHOD OF STUDY: A daily placental immune cell census was established in a murine model by flow cytometry from mid to late gestation and compared to the maternal systemic immune census. Shifts in the placental immune state were further characterized through cytokine ELISAs. RESULTS: The placental immune census is distinct from the maternal systemic immune census, although the cells are primarily maternal in origin. Near term parturition, the placenta contains fewer CD11c-positive myeloid cells and regulatory T cells, and there is a concurrent decrease in placental IL-9 and IL 35. CONCLUSION: The immune profile of the placenta demonstrates a decrease in both regulatory immune cell types and cytokines late in gestation. Establishing the placental immune population dynamics over a healthy pregnancy will allow future investigation of placental immune cells during abnormal pregnancy. PMID- 29577514 TI - Gene expression profiles of ion channels and receptors in mouse resistance arteries: Effects of cell type, vascular bed, and age. AB - OBJECTIVE: Receptors and ion channels of smooth muscle cells (SMCs) and endothelial cells (ECs) are integral to the regulation of vessel diameter and tissue blood flow. Physiological roles of ion channels and receptors in skeletal muscle and mesenteric arteries have been identified; however, their gene expression profiles are undefined. We tested the hypothesis that expression profiles for ion channels and receptors governing vascular reactivity vary with cell type, vascular bed, and age. METHODS: Mesenteric and superior epigastric arteries were dissected from Old (24-26 months) and Young (3-6 months) C57BL/6J mice. ECs and SMCs were collected for analysis with custom qRT-PCR arrays to determine expression profiles of 80 ion channel and receptor genes. Bioinformatics analyses were applied to gain insight into functional interactions. RESULTS: We identified 68 differences in gene expression with respect to cell type, vessel type, and age. Heat maps illustrate differential expression, and distance matrices predict patterns of coexpression. Gene networks based upon protein-protein interaction datasets and KEGG pathways illustrate biological processes affected by specific differences in gene expression. CONCLUSIONS: Differences in gene expression profiles are most pronounced between microvascular ECs and SMCs with subtle variations between vascular beds and age groups. PMID- 29577515 TI - Impact of previous hepatitis B infection on the clinical outcomes from chronic hepatitis C? A population-level analysis. AB - Chronic coinfection with hepatitis C virus (HCV) and hepatitis B virus (HBV) is associated with adverse liver outcomes. The clinical impact of previous HBV infection on liver disease in HCV infection is unknown. We aimed at determining any association of previous HBV infection with liver outcomes using antibodies to the hepatitis B core antigen (HBcAb) positivity as a marker of exposure. The Scottish Hepatitis C Clinical Database containing data for all patients attending HCV clinics in participating health boards was linked to the HBV diagnostic registry and mortality data from Information Services Division, Scotland. Survival analyses with competing risks were constructed for time from the first appointment to decompensated cirrhosis, hepatocellular carcinoma (HCC) and liver related mortality. Records of 8513 chronic HCV patients were included in the analyses (87 HBcAb positive and HBV surface antigen [HBsAg] positive, 1577 HBcAb positive and HBsAg negative, and 6849 HBcAb negative). Multivariate cause specific proportional hazards models showed previous HBV infection (HBcAb positive and HBsAg negative) significantly increased the risks of decompensated cirrhosis (hazard ratio [HR]: 1.29, 95% CI: 1.01-1.65) and HCC (HR: 1.64, 95% CI: 1.09-2.49), but not liver-related death (HR: 1.02, 95% CI: 0.80-1.30). This is the largest study to date showing an association between previous HBV infection and certain adverse liver outcomes in HCV infection. Our analyses add significantly to evidence which suggests that HBV infection adversely affects liver health despite apparent clearance. This has important implications for HBV vaccination policy and indications for prioritization of HCV therapy. PMID- 29577516 TI - Phylogenetic and phylodynamic analyses of hepatitis C virus subtype 1a in Okinawa, Japan. AB - Okinawa Island, located in Southern Japan, has a higher prevalence rate of hepatitis C virus subtype 1a (HCV-1a) infection than that in mainland Japan. Okinawa has a history of US military occupation after World War II. To elucidate the transmission history of HCV-1a in Okinawa, 26 whole-genome sequences were obtained from 29 patients during 2011-2016. Phylogenetic trees were reconstructed to identify the origin and characteristics of HCV-1a in Okinawa with epidemiological information. A phylogenetic tree based on whole-genome sequencing revealed that all of the samples were located below the US branches. Additionally, we identified one cluster comprised of 17 strains (Okinawa, n = 16; United States, n = 1). The majority of the patients in this cluster were people who inject drugs (PWID), indicating the presence of a people who inject drugs (PWID) cluster. Subsequently, Bayesian analyses were employed to reveal viral population dynamics. Intriguingly, a phylodynamic analysis uncovered a substantial increase in effective population size of HCV-1a from 1965 to 1980 and a slight increase in mid-2000, which were associated with an increase in illicit drug use in Okinawa. The estimated divergence time of the PWID cluster was 1967.6 (1964.2-1971.1). These findings suggest that HCV-1a was introduced into Okinawa from the United States in the late 1960s, coincident with the Vietnam War. Subsequently, HCV-1a might have spread among the Japanese population with the spread of injecting drug use. Our study provides an understanding of HCV transmission dynamics in Okinawa, as well as the key role of PWID in HCV transmission. PMID- 29577517 TI - Analysis of Metabolomic Changes in Mesenchymal Stem Cells on Treatment with Desferrioxamine as a Hypoxia Mimetic Compared with Hypoxic Conditions. AB - Mesenchymal stem cells (MSCs) are commonly used in regenerative medicine, but their therapeutic effects vary depending on the culture environment. Hypoxic culturing can be used to maintain stem cells in an undifferentiated state, but is expensive and difficult to perform. The aim of this study was to determine the effectiveness of desferrioxamine (DFO), a hypoxia-mimetic reagent, as an alternative to hypoxic culturing by analyzing metabolic changes in MSCs under hypoxic conditions compared with changes induced by DFO. Low concentrations of DFO reduced mitochondrial activity and apoptosis. Therefore, low concentrations of DFO may be useful for MSC preconditioning. Metabolome analysis showed that both hypoxic treatment and DFO administration exhibited similar metabolite patterns except purine, pyrimidine, and tricarboxylic acid cycle (TCA) cycle related metabolites. Therefore, the use of DFO at low concentrations is a potential substitute for hypoxic culturing. These findings may form the foundation for the development of future regenerative therapies using MSCs. Stem Cells 2018;36:1226-1236. PMID- 29577518 TI - Quantification of serum markers of hepatitis B (HBV) and Delta virus (HDV) infections in patients with chronic HDV infection. AB - The interplay between hepatitis B (HBV) and delta (HDV) viruses is complex and not always characterized during chronic HDV infection. We assessed the clinical usefulness of new quantitative assays for HBV and HDV serum markers in a retrospective cross-sectional study. Sera obtained from 122 HDV genotype 1 and HBV genotype D coinfected, anti-HIV-negative patients (71 males; median age 49.8 [21.7-66.9] years), recruited consecutively in two geographical areas (Italy 69 patients, Romania 53 patients) with different HBV and HDV epidemiology, were tested for HBsAg, HBV-DNA, HBcrAg, total anti-HBc, HDV-RNA, IgM and total anti HDV using quantitative assays. Cirrhosis, which showed comparable prevalence in the two cohorts, was diagnosed in 97 of 122 (79.5%) patients. At multivariate analysis, cirrhosis was associated with lower total anti-HBc/IgM anti-HDV ratio (OR 0.990, 95% CI 0.981-0.999, P = .038), whereas disease activity was associated with higher total anti-HDV (OR 10.105, 95% CI 1.671-61.107, P = .012) and HDV-RNA levels (OR 2.366, 95% CI 1.456-3.844, P = .001). HDV-RNA serum levels showed a positive correlation with HBV-DNA (rho = 0.276, P = .005), HBsAg (rho = 0.404, P < .001) and HBcrAg (rho = 0.332, P < .001). The combined quantitative profiling of HBV and HDV serum markers identifies specific patterns associated with activity and stage of chronic hepatitis D (CHD). HDV pathogenicity depends on the underlying active HBV infection in spite of the inhibition of its replication. HDV-RNA, IgM anti-HDV, total anti-HDV, total anti-HBc, HBsAg and HBcrAg serum levels qualify for prospective studies to predict progressive CHD and identify candidates to antiviral therapy. PMID- 29577519 TI - Efficacy and safety of a T-type calcium channel blocker in patients with neuropathic pain: A proof-of-concept, randomized, double-blind and controlled trial. AB - BACKGROUND: T-type calcium channels have been shown to play an important role in the initiation and maintenance of neuropathic pain and represent a promising therapeutic target for new analgesic treatments. Ethosuximide (ETX), an anticonvulsant and a T-type channel blocker has shown analgesic effect in several chronic pain models but has not yet been evaluated in patients with neuropathic pain. METHODS: This proof-of-concept, multicentre, double-blind, controlled and randomized trial compared the efficacy and safety of ETX (given as add-on therapy) to an inactive control (IC) in 114 patients with non-diabetic peripheral neuropathic pain. After a 7-day run-in period, eligible patients aged over 18 years were randomly assigned (1:1) to ETX or IC for 6 weeks. The primary outcome was the difference between groups in the pain intensity (% of change from the baseline to end of treatment) assessed in the intention-to-treat population. This study is registered with EudraCT (2013-004801-26) and ClinicalTrials.gov (NCT02100046). RESULTS: The study was stopped during the interim analysis due to the high number of adverse events in the active treatment group. ETX failed to reduce total pain and showed a poor tolerance in comparison to IC. In the per protocol analysis, ETX significantly reduced pain intensity by 15.6% (95% CI 25.8; -5.4) from baseline compared to IC (-7.8%, 95% CI -14.3; -1.3; p = 0.033), but this result must be interpreted with caution because of a small subgroup of patients. CONCLUSION: Ethosuximide did not reduce the severity of neuropathic pain and induces, at the doses used, many adverse events. SIGNIFICANCE: This article shows that ETX is not effective to treat neuropathic pain. Nevertheless, per-protocol analysis suggests a possible analgesic effect of ETX. Thus, our work adds significant knowledge to preclinical and clinical data on the benefits of T type calcium channel inhibition for the treatment of neuropathic pain. PMID- 29577520 TI - The impact of thromboelastography on resuscitation in pediatric liver transplantation. AB - Although TEG directs effective resuscitation in adult surgical patients, pediatric data are lacking. We performed a retrospective comparative review of the effect of TEG on blood product utilization and outcomes following pediatric liver transplantation in 38 patients between 2008 and 2014. Diagnoses, laboratory values, fluid and blood product use, and outcomes were examined. Nineteen patients underwent liver transplantation prior to the implementation of TEG, and 19 had perioperative TEG. The most common indications for transplant were BA (n = 14), HB (n = 7), and metabolic disorders (n = 7). Intraoperative blood loss, urine output, fluid and blood product use were similar between groups. However, the use of fresh frozen plasma decreased significantly in TEG patients within the first 24 hours (29 vs 0 mL/kg, P < .01), and between 24 and 48 hours (12 vs 0 mL/kg, P = .01) post-operatively. The total use of fresh frozen plasma during hospitalization was markedly reduced (111 vs 17 mL/kg, P < .01). Four patients in the TEG group had thromboembolic graft complications, including portal vein or hepatic artery thrombosis, and underwent retransplantation. The decreased use of fresh frozen plasma since implementation of TEG is an important finding for resource utilization and patient safety. However, the increased incidence of thromboembolic complications requires further investigation. PMID- 29577521 TI - How phonological awareness mediates the relation between working memory and word reading efficiency in children with dyslexia. AB - This study examined the relation between working memory, phonological awareness, and word reading efficiency in fourth-grade children with dyslexia. To test whether the relation between phonological awareness and word reading efficiency differed for children with dyslexia versus typically developing children, we assessed phonological awareness and word reading efficiency in 50 children with dyslexia (aged 9;10, 35 boys) and 613 typically developing children (aged 9;5, 279 boys). Phonological awareness was found to be associated with word reading efficiency, similar for children with dyslexia and typically developing children. To find out whether the relation between working memory and word reading efficiency in the group with dyslexia could be explained by phonological awareness, the children with dyslexia were also tested on working memory. Results of a mediation analysis showed a significant indirect effect of working memory on word reading efficiency via phonological awareness. Working memory predicted reading efficiency, via its relation with phonological awareness in children with dyslexia. This indicates that working memory is necessary for word reading efficiency via its impact on phonological awareness and that phonological awareness continues to be important for word reading efficiency in older children with dyslexia. PMID- 29577522 TI - Fear of pain and cortisol reactivity predict the strength of stress-induced hypoalgesia. AB - BACKGROUND: Acute stress can have an effect on pain sensitivity, yet the direction of the effect - whether it is hypoalgesic or hyperalgesic - is mixed across studies. Moreover, which part of the stress response influences pain sensitivity is still unclear. In the current experimental study, we aim to examine the effect of acute stress on heat pain thresholds and pain tolerance levels in healthy participants, while taking into account individual differences in stress responses. METHODS: Forty-two healthy participants were randomly assigned to either a well-validated stress paradigm: the Maastricht Acute Stress Task (MAST; combining physical and psychological stressors) or to a nonstressful version of the task. Heat pain thresholds and tolerance levels were assessed at three times: prior to the MAST, immediately after the MAST during the presumed sympatho-adrenal medullary (SAM) response, and 15 min after MAST to cover the presumed hypothalamus-pituitary-adrenal (HPA) axis response. Stress responses were assessed both subjectively and physiologically. RESULTS: We observed that the acute stress induction led to increased heat pain thresholds, an effect that was present only in participants showing a cortisol response following stress induction and only in the presumed HPA axis time window. The strength of this hypoalgesic effect was further predicted by the change in cortisol and by fear of pain levels. CONCLUSIONS: Our findings indicate that the HPA axis - and not the autonomic - stress response specifically underlies this stress-induced hypoalgesic effect, having important implications for clinical states with HPA axis dysfunctions. SIGNIFICANCE: This experimental study shows that an acute stress induction - that combines physical and psychological stressors - increases heat pain thresholds, but not tolerance in healthy participants. Furthermore, the magnitude of this stress-induced hypoalgesic effect is predicted by cortisol reactivity and fear of pain, revealing specific involvement of the HPA axis stress system and interactions with pain-related psychosocial aspects. PMID- 29577523 TI - What's in a name? Perspectives of dyslexia assessors working with students in the UK higher education sector. AB - Research findings and positions concerning the nature of the dyslexia construct are currently diverse and increasingly complex. The ability of assessor practitioners to operationalize such knowledge and categorically diagnose dyslexia in any reliable and consistent way is being questioned. This study aimed to explore the way in which diverse and complex research findings are operationalized in the dyslexia diagnostic assessment of UK higher education students. The perspectives of 118 professional assessors of dyslexia working within the sector were collected using a questionnaire and some interviews. Data were analysed both quantitatively and qualitatively, as appropriate, and then integrated. The results confirmed critics' concerns about the consistency and reliability of the construct as currently diagnosed within the higher education context. Key controversial aspects of practice that emerged included the contextualized interpretation of literacy difficulties, a general commitment to discrepancy concepts, scepticism about the face validity of prescribed psychometric tests, and a related reliance on professional observation and experience above test results. The findings pointed to the need for a more informed nuanced understanding of the dyslexia label and a more cautious and responsible attitude towards its use. PMID- 29577524 TI - Pulmonary infarction secondary to pulmonary embolism: An evolving paradigm. AB - BACKGROUND AND OBJECTIVE: Pulmonary infarction (PI) from pulmonary embolism (PE) remains an entity of unclear aetiology. PI has been thought to occur in elderly patients with cardiopulmonary disease. We hypothesize younger patients without cardiopulmonary comorbidities are at highest risk. Our study aims to characterize PI clinically and radiographically, determine associated risk factors and determine their clinical significance. METHODS: We conducted a single-centre retrospective review of 367 consecutive patients with PE. Clinical and radiographic data were compared between patients with and without PI using chi square and F-tests. Univariate and multivariate analyses were performed to evaluate risk factors for PI. RESULTS: PI occurred in 62 of 367 patients with acute PE (16.9%). Patients with PI were significantly younger (48 +/- 20.3 vs 59.6 +/- 17.2 years, P < 0.01), with lower pulmonary embolism severity index (PESI) scores (73.7 +/- 38.1 vs 91.9 +/- 37.5 years, P < 0.01) and endorsed chest pain with significantly higher frequency (65% vs 39%, P < 0.01). There was no significant difference in other clinical symptoms, hospital length of stay or mortality between groups. Presence of radiographic cardiopulmonary disease was significantly lower in patients with PI (emphysema: 5% vs 22%, P = <0.01; aortic atherosclerosis: 23% vs 43%, P = <0.01). In multivariate analysis, age <=33 (OR 3.5 CI: 1.37-8.95, P < 0.01), chest pain (OR 2.15 CI: 1.15-4.00, P = 0.02) and pleural effusion (OR 2.18 CI: 1.08-4.41, P = 0.03) increased PI risk and presence of emphysema decreased risk (OR 0.21 CI: 0.06-0.70, P = 0.01). CONCLUSION: Younger patients without cardiopulmonary comorbidities are at highest risk of PI. Chest pain and pleural effusion significantly increased risk of PI while presence of radiographic emphysema reduced risk. PMID- 29577525 TI - Post-hematopoietic stem cell transplant hemophagocytic lymphohistiocytosis or an impostor: Case report and review of literature. AB - HLH occurring after HSCT is a relatively rare disease. Many conditions may mimic or trigger HLH in post-HSCT period (eg, cytokine release syndrome, engraftment syndrome, graft rejection/failure, acute graft-vs-host disease, infections systemic inflammatory response syndrome/sepsis, and thrombotic microangiopathy). Moreover, this period is usually marked by febrile illness, cytopenia, and a "cytokine storm" leading to elevation of inflammatory biomarkers like ferritin and sCD25. These parameters overlap with the diagnostic criteria for HLH. Such confounding factors make the management of post-HSCT HLH quite challenging. We illustrate this critical issue with case report of a patient who was diagnosed with HLH after allogeneic HSCT for tAML. He received MP and CsA for HLH but VP-16 was not administered due to fear of severe myelosuppression. Fortunately, he responded well to treatment and remains in remission to date. We recommend caution while using HLH-94/HLH-2004 guidelines for the diagnosis and management of post-HSCT HLH. In this article, we pinpoint these issues with a brief review of all the pediatric cases and clinical studies of post-HSCT HLH along with a critical evaluation of its various diagnostic criteria. Finally, based on the limitations of current diagnostic criteria, we suggest a need for formulating disease-specific diagnostic criteria for post-HSCT HLH. PMID- 29577527 TI - Endosomal sorting complexes required for ESCRTing cells toward death during neurogenesis, neurodevelopment and neurodegeneration. AB - The endosomal sorting complexes required for transport (ESCRT) proteins help in the recognition, sorting and degradation of ubiquitinated cargoes from the cell surface, long-lived proteins or aggregates, and aged organelles present in the cytosol. These proteins take part in the endo-lysosomal system of degradation. The ESCRT proteins also play an integral role in cytokinesis, viral budding and mRNA transport. Many neurodegenerative diseases are caused by toxic accumulation of cargo in the cell, which causes stress and ultimately leads to neuronal death. This accumulation of cargo occurs because of defects in the endo-lysosomal degradative pathway-loss of function of ESCRTs has been implicated in this mechanism. ESCRTs also take part in many survival processes, lack of which can culminate in neuronal cell death. While the role played by the ESCRT proteins in maintaining healthy neurons is known, their role in neurodegenerative diseases is still poorly understood. In this review, we highlight the importance of ESCRTs in maintaining healthy neurons and then suggest how perturbations in many of the survival mechanisms governed by these proteins could eventually lead to cell death; quite often these correlations are not so obviously laid out. Extensive neuronal death eventually culminates in neurodegeneration. PMID- 29577526 TI - Assessment of bulbar function in amyotrophic lateral sclerosis: validation of a self-report scale (Center for Neurologic Study Bulbar Function Scale). AB - BACKGROUND AND PURPOSE: Impaired bulbar functions of speech and swallowing are among the most serious consequences of amyotrophic lateral sclerosis (ALS). Despite this, clinical trials in ALS have rarely emphasized bulbar function as an endpoint. The rater-administered Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) or various quality-of-life measures are commonly used to measure symptomatic benefit. Accordingly, we sought to evaluate the utility of measures specific to bulbar function in ALS. METHODS: We assessed bulbar functions in 120 patients with ALS, with clinicians first making direct observations of the degree of speech, swallowing and salivation impairment in these subjects. Clinical diagnosis of bulbar impairment was then compared with ALSFRS-R scores, speech rate, time to swallow liquids and solids, and scores obtained when patients completed visual analog scales (VASs) and the newly developed 21-question self-administered Center for Neurologic Study Bulbar Function Scale (CNS-BFS). RESULTS: The CNS-BFS, ALSFRS-R, VAS and timed speech and swallowing were all concordant with clinician diagnosis. The self-report CNS BFS and ALSFRS-R bulbar subscale best predicted clinician diagnosis with misclassification rates of 8% and 14% at the optimal cut-offs, respectively. In addition, the CNS-BFS speech and swallowing subscales outperformed both the bulbar component of the ALSFRS-R and speech and swallowing VASs when correlations were made between these scales and objective measures of timed reading and swallowing. CONCLUSIONS: Based on these findings and its relative ease of administration, we conclude that the CNS-BFS is a useful metric for assessing bulbar function in patients with ALS.

AB - The performance of seedlings is crucial for the survival and persistence of plant populations. Although drought frequently occurs in floodplains and can cause seedling mortality, studies on the effects of drought on seedlings of floodplain grasslands are scarce. We tested the hypotheses that drought reduces aboveground biomass, total biomass, plant height, number of leaves, leaf area and specific leaf area (SLA), and increases root biomass and root-mass fraction (RMF) and that seedlings from species of wet floodplain grasslands are more affected by drought than species of dry grasslands. In a greenhouse study, we exposed seedlings of three confamilial pairs of species (Pimpinella saxifraga, Selinum carvifolia, Veronica teucrium, Veronica maritima, Sanguisorba minor, Sanguisorba officinalis) to increasing drought treatments. Within each plant family, one species is characteristic of wet and one of dry floodplain grasslands, confamilial in order to avoid phylogenetic bias of the results. In accordance with our hypotheses, drought conditions reduced aboveground biomass, total biomass, plant height, number of leaves and leaf area. Contrary to our hypotheses, drought conditions increased SLA and decreased root biomass and RMF of seedlings. Beyond the effects of the families, the results were species-specific (V. maritima being the most sensitive species) and habitat-specific. Species indicative of wet floodplain grasslands appear to be more sensitive to drought than species indicative of dry grasslands. Because of species- and habitat-specific responses to reduced water availability, future drought periods due to climate change may severely affect some species from dry and wet habitats, while others may be unaffected. PMID- 29577529 TI - Quality of life in children with developmental language disorder. AB - BACKGROUND: Developmental language disorder (DLD) is common in children, but little is known about its association with quality of life (QoL) in middle childhood. QoL is a complex construct, aligning with an individual's sense of well-being and is related to functional limitations associated with DLD. Biopsychosocial models of disability account for both the extent and functional limitations of the impairment; however, the DLD literature rarely reports on both aspects. Studies are required that detail QoL in children with and without DLD. AIMS: To investigate the association between DLD, identified at 4 years and persisting at 7 years, and QoL over 4, 7 and 9 years; to compare QoL for children whose DLD was mild to moderate and severe at 7 years; and to investigate how variables known to impact on language development (e.g., maternal vocabulary), as well as social-emotional behaviours at 4 and 7 years contribute to QoL at 9 years. METHODS & PROCEDURES: The analyses included 872 children who participated in the 4-, 7- and 9-year data collection of the Early Language in Victoria Study (ELVS). We compared the parent-reported QoL profiles at 4, 7 and 9 years for children with and without DLD, and those with mild to moderate and severe DLD using the Pediatric Quality of Life Inventory (PedsQL). We conducted regression analyses to estimate how child, family and environmental factors predicted QoL at 9 years, including social-emotional behaviours measured using the Strengths & Difficulties Questionnaire (SDQ) at 4 and 7 years. OUTCOME & RESULTS: Children with DLD (n = 70) had lower parent-reported QoL at 9 years than typically developing children (n = 802), with mean scores of 74.9 and 83.9 respectively. There was no evidence of differences in QoL between those with severe (n = 14) or mild to moderate (n = 56) DLD. In contrast to their peers, children with DLD had a profile of declining QoL between 4 and 9 years. For all children, language skills at 7 years predicted QoL at 9 years. For children with DLD, emotional symptoms and peer problems at 4 years plus SDQ Total Difficulties at 7 years were predictive of lower QoL at 9 years. CONCLUSIONS & IMPLICATIONS: Children with DLD had a lower QoL than their typical peers at 9 years and, contrary to previous studies, differences in QoL were not observed with DLD severity. Co-occurring social-emotional problems appear to play an important role in contributing to the lower QoL experienced by children with DLD. Consideration of associated functional limitations is required to support the communication and social development of all young children with DLD. PMID- 29577530 TI - Induction of Signal Transduction by Using Non-Channelrhodopsin-Type Optogenetic Tools. AB - Signal transductions are the basis for all cellular functions. Previous studies investigating signal transductions mainly relied on pharmacological inhibition, RNA interference, and constitutive active/dominant negative protein expression systems. However, such studies do not allow the modulation of protein activity with high spatial and temporal precision in cells, tissues, and organs in animals. Recently, non-channelrhodopsin-type optogenetic tools for regulating signal transduction have emerged. These photoswitches address several disadvantages of previous techniques, and allow us to control a variety of signal transductions such as cell membrane dynamics, calcium signaling, lipid signaling, and apoptosis. In this review we summarize recent advances in the development of such photoswitches and in how these optotools are applied to signaling processes. PMID- 29577531 TI - Burden of illness and costs among paediatric haemophilia patients with and without central venous access devices treated in US hospitals. AB - INTRODUCTION: Central venous access devices (CVADs) facilitate repeated or urgent treatments for paediatric haemophilia patients, but are associated with complications. This study examined the burden of illness, healthcare utilization and costs for CVADs in a real-world hospital setting. MATERIALS AND METHODS: This study included haemophilia patients ages <=18 years with discharges during 2006 2014 in the US Premier Healthcare Database. Haemophilia was identified using ICD 9 diagnosis codes and CVAD exposure using billing information. After matching haemophilia patients with and without CVADs on demographic and clinical characteristics, we compared infection, thrombosis, length of stay (LOS), inflation-adjusted hospital cost (2014 $USD) and readmission outcomes using generalized estimating equation models adjusted for hospital teaching status. RESULTS: Among 4793 paediatric haemophilia patients treated at one of 548 hospitals, a total of 197 patients were identified with CVAD exposure. The matched sample included 310 haemophilia patients (155 CVAD and 155 non-CVAD). CVAD cases had greater frequencies of all-cause infections (29% vs 17%, P = .01) and thrombosis (6% vs 1%, P = .06), longer adjusted mean LOS (9.5 vs 4.7 days, P = .002), higher adjusted mean inpatient total hospitalization costs ($47200 vs $25389, P = .02) as well as more inpatient and outpatient visits at 30-, 60- and 90-days (P < .05 for all differences) compared with non-CVAD patients. CONCLUSION: Paediatric haemophilia patients with CVADs experienced greater infection rates, healthcare utilization and higher hospitalization costs compared with non-CVAD patients. The results of this study may inform further research efforts to understand the costs and benefits of novel treatment alternatives for young haemophilia patients requiring CVADs.

AB - Singly and doubly 1,2-phenylene-inserted NiII porphyrin arch-tape dimers 3 and 9 were synthesized from the corresponding beta-to-beta 1,2-phenylene-bridged NiII porphyrin dimers 5 and 11 via Ni0 -mediated reductive cyclization and DDQ/Sc(OTf)3 -promoted oxidative cyclization as key steps, respectively. Owing to the fused eight-membered ring(s), 3 showed a more contorted structure than those of previously reported arch-tape dimers 2 a and 2 b possessing a fused seven membered ring. Furthermore, 9 displayed much larger molecular contortion. As the molecular contortion increases, the Q band of the absorption spectrum becomes more red-shifted and the electrochemcial HOMO-LUMO gap becomes smaller, reaching at 1294 nm and 0.77 eV in 9, respectively. The effect of molecular contortion on the electronic properties was studied by means of DFT calculations. PMID- 29577533 TI - Local Atomic Arrangements and Band Structure of Boron Carbide. AB - Boron carbide, the simple chemical combination of boron and carbon, is one of the best-known binary ceramic materials. Despite that, a coherent description of its crystal structure and physical properties resembles one of the most challenging problems in materials science. By combining ab initio computational studies, precise crystal structure determination from diffraction experiments, and state of-the-art high-resolution transmission electron microscopy imaging, this concerted investigation reveals hitherto unknown local structure modifications together with the known structural alterations. The mixture of different local atomic arrangements within the real crystal structure reduces the electron deficiency of the pristine structure CBC+B12 , answering the question about electron precise character of boron carbide and introducing new electronic states within the band gap, which allow a better understanding of physical properties.

AB - Presented herein is an unprecedented transition-metal-free propargylic substitution reaction with either azolium enolates or acyl anions, which are generated from aldehydes under N-heterocyclic carbene catalysis. This new catalytic activation operates on readily available cyclic propargylic carbamates through decarboxylation, and generates reactive allene intermediates that can undergo divergent cyclization pathways to deliver skeletally diverse polycyclic compounds with high levels of efficiency and excellent enantioselectivities. PMID- 29577535 TI - A [RuRu] Analogue of an [FeFe]-Hydrogenase Traps the Key Hydride Intermediate of the Catalytic Cycle. AB - The active site of the [FeFe]-hydrogenases features a binuclear [2Fe]H sub cluster that contains a unique bridging amine moiety close to an exposed iron center. Heterolytic splitting of H2 results in the formation of a transient terminal hydride at this iron site, which, however is difficult to stabilize. We show that the hydride intermediate forms immediately when [2Fe]H is replaced with [2Ru]H analogues through artificial maturation. Outside the protein, the [2Ru]H analogues form bridging hydrides, which rearrange to terminal hydrides after insertion into the apo-protein. H/D exchange of the hydride only occurs for [2Ru]H analogues containing the bridging amine moiety. PMID- 29577537 TI - Peer work in Open Dialogue: A discussion paper. AB - Open Dialogue is a resource-oriented approach to mental health care that originated in Finland. As Open Dialogue has been adopted across diverse international healthcare settings, it has been adapted according to contextual factors. One important development in Open Dialogue has been the incorporation of paid, formal peer work. Peer work draws on the knowledge and wisdom gained through lived experience of distress and hardship to establish mutual, reciprocal, and supportive relationships with service users. As Open Dialogue is now being implemented across mental health services in Australia, stakeholders are beginning to consider the role that peer workers might have in this model of care. Open Dialogue was not, initially, conceived to include a specific role for peers, and there is little available literature, and even less empirical research, in this area. This discussion paper aims to surface some of the current debates and ideas about peer work in Open Dialogue. Examples and models of peer work in Open Dialogue are examined, and the potential benefits and challenges of adopting this approach in health services are discussed. Peer work in Open Dialogue could potentially foster democracy and disrupt clinical hierarchies, but could also move peer work from reciprocal to a less symmetrical relationship of 'giver' and 'receiver' of care. Other models of care, such as lived experience practitioners in Open Dialogue, can be conceived. However, it remains uncertain whether the hierarchical structures in healthcare and current models of funding would support any such models. PMID- 29577536 TI - Hypoglycaemia incidence and recovery during home use of hybrid closed-loop insulin delivery in adults with type 1 diabetes. AB - Glucose excursion was assessed prior to and post hypoglycaemia to increase understanding of hypoglycaemia incidence and recovery during hybrid closed-loop insulin delivery. We retrospectively analysed data from 60 adults with type 1 diabetes who received, in a crossover randomized design, day-and-night hybrid closed-loop insulin delivery and insulin pump therapy, the latter with or without real-time continuous glucose monitoring. Over 4-week study periods, we identified hypoglycaemic episodes, defined as sensor glucose <3.0 mmol/L, and analysed sensor glucose relative to the onset of hypoglycaemia. We identified 377 hypoglycaemic episodes during hybrid closed-loop intervention vs 662 during control intervention (P < .001), with a predominant reduction of nocturnal hypoglycaemia. The slope of sensor glucose prior to hypoglycaemia was steeper during closed-loop intervention than during control intervention (P < .01), while insulin delivery was reduced (P < .01). During both day and night, participants recovered from hypoglycaemia faster when treated by closed-loop intervention. At 120 minutes post hypoglycaemia, sensor glucose levels were higher during closed loop intervention compared to the control period (P < .05). In conclusion, closed loop intervention reduces the risk of hypoglycaemia, particularly overnight, with swift recovery from hypoglycaemia leading to higher 2-hour post-hypoglycaemia glucose levels. PMID- 29577539 TI - The prognosis for glycemic status among children and youth with obesity 2 years after entering a weight management program. AB - BACKGROUND: To address gaps in knowledge of the longitudinal trajectory of dysglycemia in children with obesity, this study aimed to: (1) describe the changes in glycemic status over 2 years; (2) establish a predictive model for development of prediabetes among children with euglycemia; and (3) evaluate the influence of change in body mass index (BMI) z-score on glycemic status. METHODS: Children aged 5 to 17 years entered this prospective, longitudinal study at the time of entry to a weight management program. Measures included a 75-g oral glucose tolerance test (OGTT), fasting blood glucose, hemoglobin A1c (HbA1c), lipid profile, liver enzymes and anthropometric measures at baseline, 1 and 2 years. Cox proportional hazard was used to build a predictive model for prediabetes. RESULTS: The cohort included 270 children, mean age: 11.6 +/- 2.7 years and BMI z-score: 3.1. The baseline prevalence of prediabetes, based upon elevated 2-hour glucose in OGTT or HbA1c, was 100/270 (37.0%). Among children with prediabetes at baseline, 53 (53.0%) continued to have prediabetes over the following 2 years, 15 (15.0%) were euglycemic at 1 year and had prediabetes at 2 years, 20 (20.0%) became euglycemic and remained so. Change in BMI z-score predicted dysglycemic status at 2 years. Among those euglycemic at baseline, the incidence of prediabetes was 14 (8.2%) after 1 year, 20 (12.8%) at 2 years. Predictors of incident prediabetes were baseline BMI z-score; hazard ratio (HR): 1.72, 95th confidence interval (CI: 1.08, 2.74) and baseline HbA1c HR: 1.26, 95th CI (1.02-1.56) when controlling for age, family history of diabetes and sex. CONCLUSION: Prediabetes presents significant morbidity in children with obesity. Family-based lifestyle interventions might delay prediabetes progression. PMID- 29577538 TI - Family adjustment to diabetes diagnosis in children: Can participation in a study on type 1 diabetes genetic risk be helpful? AB - BACKGROUND: Diagnosis of type 1 diabetes often causes a negative psychological impact on families. We examined whether parents and children enrolled in The Environmental Determinants of Diabetes in the Young (TEDDY) study differ in their psychological adjustment to diabetes diagnosis compared to children diagnosed with diabetes in the community. METHODS: TEDDY follows 8676 children at genetic risk for type 1 diabetes from birth. Fifty-four TEDDY children diagnosed with diabetes and 54 age-matched community control children diagnosed with diabetes were enrolled. Participants were aged 3 to 10 years and study visits occurred at 3, 6, and 12 months postdiagnosis. Psychological measures included an adapted diabetes-specific State Anxiety Inventory, the Pediatric Quality of Life Inventory-Diabetes Module, and the Pediatric Inventory for Parents, which measures frequency and difficulty of parenting stress. RESULTS: A generalized estimating equation analysis based on a difference score between TEDDY children and community controls found no significant differences between TEDDY parents and community controls on parent diabetes-specific anxiety (P = .30). However, TEDDY children exhibited better diabetes-specific quality of life (P = .03) and TEDDY parents reported lower frequency (P = .004) and difficulty (P = .008) of parenting stress compared to community controls. CONCLUSIONS: Children diagnosed with at-risk for type 1 diabetes who have previously enrolled in research monitoring have improved diabetes quality of life and lower parenting stress postdiagnosis compared to children diagnosed in the community. Families in follow up studies may be more prepared if their child is diagnosed with diabetes. PMID- 29577540 TI - Burden of cardio-renal-metabolic conditions in adults with type 2 diabetes within the Diabetes Collaborative Registry. AB - We examined the prevalence of cardio-renal-metabolic (CaReMe) conditions and their combinations among 530 747 adults with type 2 diabetes in a USA-based outpatient registry of 271 primary care, cardiology and endocrinology offices. We evaluated the following CaReMe conditions: hypertension, hyperlipidaemia, coronary artery disease (CAD), chronic kidney disease (CKD), cerebrovascular disease, peripheral artery disease, atrial fibrillation, heart failure, and gout or hyperuricaemia; prevalence estimates were adjusted based on the distribution of diabetes by age in the US population in 2015. We found that it was uncommon for patients to have isolated type 2 diabetes without other CaReMe conditions, with only 6.4% having no other CaReMe conditions and 51% having >=3 other CaReMe conditions. The most prevalent individual conditions were hypertension (83%), hyperlipidemia (81%), CAD (32%) and CKD (20%), and the most common combinations included various groupings of hypertension, hyperlipidaemia, atherosclerotic cardiovascular disease and CKD. Older age, male sex and tobacco use were each associated with increased numbers of CaReMe conditions. These findings highlight the clinical need for novel treatment strategies for diabetes that address both glycaemia and coexisting disease states. PMID- 29577541 TI - Prognostic value of inferior mesenteric artery lymph node metastasis in cancer of the descending colon, sigmoid colon and rectum. AB - AIM: This study aimed to analyse the potential significance of metastasis to the inferior mesenteric artery lymph node (IMA-LN) in patients with malignancy of the left colon and rectum. METHOD: A retrospective analysis of a cohort of 890 patients collected prospectively who underwent radical resection of a primary tumour of the descending colon, sigmoid colon and rectum in our department from 1 January 2009 to 31 December 2015 was performed. Patients were divided into an IMA LN metastasis (IMA-LN (+)) group (n = 51) and a non IMA-LN metastasis (IMA-LN ( )) group (n = 839). A total of 801 patients were followed by a designated member of the study staff. Clinical features, pathological characteristics, recurrence patterns and survival rates were compared between the two groups. RESULTS: In the IMA-LN (+) group, the risk ratio of overall recurrence and tumour related death was 7.786 (95% CI 4.142-14.637) and 7.756 (95% CI 4.142-14.525) respectively. Significant differences were found in overall survival (log-rank: chi2 = 69.06, P < 0.0001) and disease-free survival (log-rank: chi2 = 69.06, P < 0.0001) between the two groups. Furthermore, there were significant differences in overall survival (log-rank: chi2 = 18.47, P < 0.0001) and disease-free survival (log-rank: chi2 = 16.99, P < 0.0001) between the IMA-LN (-) and IMA-LN (+) subgroups of patients with Stage N2 disease. Multivariate survival analysis indicated that IMA-LN (+) was an independent risk factor of poor prognosis. There was no difference in the prognosis between high tie and low tie with IMA-LN dissection. CONCLUSION: Inferior mesenteric artery lymph node metastasis was an independent predictive factor for high systemic recurrence. Low ligation of the IMA with IMA-LN dissection was not inferior to high ligation. PMID- 29577543 TI - A Forkhead Box Protein C2 Inhibitor: Targeting Epithelial-Mesenchymal Transition and Cancer Metastasis. AB - The epithelial-mesenchymal transition (EMT) has been suggested as a new target for therapeutic intervention of metastatic cancer. Forkhead box protein C2 (FOXC2) is known to be necessary for initiating and maintaining EMT, and therefore bestows on cancer cells metastatic and cancer stem cell (CSC)-like phenotypes, allowing cells to acquire higher motility, invasiveness, self renewal, and therapy resistance. Here, we describe the first inhibitor of FOXC2, MC-1-F2. MC-1-F2 was able to induce cadherin switching and reverse EMT through the degradation of FOXC2 and blocking of its nuclear localization. In addition, MC-1-F2 was very effective in inhibiting cancer cell migration and invasion. As the first small-molecule inhibitor of FOXC2 and the first compound targeting EMT associated transcription factor, MC-1-F2 will pave the way for a new anticancer therapeutic agent targeting metastatic cancer and help to elucidate the network of EMT signaling pathways. PMID- 29577542 TI - Further analysis of barley MORC1 using a highly efficient RNA-guided Cas9 gene editing system. AB - Microrchidia (MORC) proteins comprise a family of proteins that have been identified in prokaryotes and eukaryotes. They are defined by two hallmark domains: a GHKL-type ATPase and an S5-fold. In plants, MORC proteins were first discovered in a genetic screen for Arabidopsis thaliana mutants compromised for resistance to a viral pathogen. Subsequent studies expanded their role in plant immunity and revealed their involvement in gene silencing and genome stabilization. Little is known about the role of MORC proteins of cereals, especially because knockout (KO) mutants were not available and assessment of loss of function relied only on RNAi strategies, which were arguable, given that MORC proteins in itself are influencing gene silencing. Here, we used a Streptococcus pyogenes Cas9 (SpCas9)-mediated KO strategy to functionally study HvMORC1, one of the current seven MORC members of barley. Using a novel barley RNA Pol III-dependent U3 small nuclear RNA (snRNA) promoter to drive expression of the synthetic single guide RNA (sgRNA), we achieved a very high mutation frequency in HvMORC1. High frequencies of mutations were detectable by target sequencing in the callus, the T0 generation (77%) and T1 generation (70%-100%), which constitutes an important improvement of the gene-editing technology in cereals. Corroborating and extending earlier findings, SpCas9-edited hvmorc1-KO barley, in clear contrast to Arabidopsis atmorc1 mutants, had a distinct phenotype of increased disease resistance to fungal pathogens, while morc1 mutants of either plant showed de-repressed expression of transposable elements (TEs), substantiating that plant MORC proteins contribute to genome stabilization in monocotyledonous and dicotyledonous plants.

PMID- 29577545 TI - Efficient genome editing of wild strawberry genes, vector development and validation. AB - The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 system is an effective genome editing tool for plant and animal genomes. However, there are still few reports on the successful application of CRISPR-Cas9 to horticultural plants, especially with regard to germ-line transmission of targeted mutations. Here, we report high-efficiency genome editing in the wild strawberry Fragaria vesca and its successful application to mutate the auxin biosynthesis gene TAA1 and auxin response factor 8 (ARF8). In our CRISPR system, the Arabidopsis U6 promoter AtU6-26 and the wild strawberry U6 promoter FveU6-2 were each used to drive the expression of sgRNA, and both promoters were shown to lead to high-efficiency genome editing in strawberry. To test germ-line transmission of the edited mutations and new mutations induced in the next generation, the progeny of the primary (T0) transgenic plants carrying the CRISPR construct was analysed. New mutations were detected in the progeny plants at a high efficiency, including large deletions between the two PAM sites. Further, T1 plants harbouring arf8 homozygous knockout mutations grew considerably faster than wild-type plants. The results indicate that our CRISPR vectors can be used to edit the wild strawberry genome at a high efficiency and that both sgRNA design and appropriate U6 promoters contribute to the success of genomic editing. Our results open up exciting opportunities for engineering strawberry and related horticultural crops to improve traits of economic importance. PMID- 29577546 TI - Thesium linophyllon parasitizes and suppresses expansive Calamagrostis epigejos. AB - Root-hemiparasitic interaction between the dominant grass Calamagrostis epigejos and the hemiparasite Thesium linophyllon was studied to assess the potential of the parasite to regulate dominance of the grass, which is expanding into species rich steppe grasslands. First, we aimed to identify physiological links between the two species as a principal indicator of the parasitic relationship. Second, we analysed the dynamics of the two species in the vegetation of a steppe grassland at the foot of the Bukk Mountains, Hungary, where their joint presence is recorded in a long-term permanent plot monitoring dataset to detect patterns associated with the parasitic ecological interaction. Numerous well-developed functional haustoria of Th. linophyllon were identified on the root systems of C. epigejos. The joint dynamics of C. epigejos and Th. linophyllon displayed clear signs of the parasitic interaction: (1) the dynamics of Th. linophyllon frequency was positively associated with the initial cover of C. epigejos; (2) maximum recorded cover values of the two species were strongly positively correlated; and (3) the extent of C. epigejos decrease in the vegetation was significantly positively associated with maximum Th. linophyllon cover recorded throughout the monitoring period. We demonstrate that C. epigejos can be parasitized by Th. linophyllon, which restricts abundance of the grass. Th. linophyllon thus has potential to act as a native biological control of C. epigejos in steppe grasslands.

AB - The plastidic glutamine synthetase isoform (GS2) plays a key role in nitrogen (N) assimilation. We introduced TaGS2-2Abpro::TaGS2-2Ab, the favourable allele of TaGS2-2A in the winter wheat (Triticum aestivum) variety Ji5265. Transgenic expression of TaGS2-2Ab significantly increased GS2 abundance and GS activity in leaves. Two consecutive field experiments showed the transgenic lines had higher grain yield, spike number, grain number per spike and 1000-grain weight than did the wild type under both low N and high N conditions. Analysis of N use-related traits showed that transgenic expression of TaGS2-2Ab increased root ability to acquire N, N uptake before and after flowering, remobilization of N to grains and N harvest index. Measurement of chlorophyll content and net photosynthesis rate in flag leaves during grain filling stage revealed that the transgenic lines had prolonged leaf functional duration as compared with the wild type. These results suggest that TaGS2 plays important role in N use, and the favourable allele TaGS2 2Ab is valuable in engineering wheat with improved N use efficiency and grain yield. PMID- 29577549 TI - What the ~1.4 Ga Xiamaling Formation can and cannot tell us about the mid Proterozoic ocean. AB - Despite a surge of recent work, the evolution of mid-Proterozoic oceanic atmospheric redox remains heavily debated. Constraining the dynamics of Proterozoic redox evolution is essential to determine the role, if any, that anoxia played in protracting the development of eukaryotic diversity. We present a multiproxy suite of high-resolution geochemical measurements from a drill core capturing the ~1.4 Ga Xiamaling Formation, North China Craton. Specifically, we analyzed major and trace element concentrations, sulfur and molybdenum isotopes, and iron speciation not only to better understand the local redox conditions but also to establish how relevant our data are to understanding the contemporaneous global ocean. Our results suggest that throughout deposition of the Xiamaling Formation, the basin experienced varying degrees of isolation from the global ocean. During deposition of the lower organic-rich shales (130-85 m depth), the basin was extremely restricted, and the reservoirs of sulfate and trace metals were drawn down almost completely. Above a depth of 85 m, shales were deposited in dominantly euxinic waters that more closely resembled a marine system and thus potentially bear signatures of coeval seawater. In the most highly enriched sample from this upper interval, the concentration of molybdenum is 51 ppm with a delta98 Mo value of +1.70/00. Concentrations of Mo and other redox-sensitive elements in our samples are consistent with a deep ocean that was largely anoxic on a global scale. Our maximum delta98 Mo value, in contrast, is high compared to published mid-Proterozoic data. This high value raises the possibility that the Earth's surface environments were transiently more oxygenated at ~1.4 Ga compared to preceding or postdating times. More broadly, this study demonstrates the importance of integrating all available data when attempting to reconstruct surface O2 dynamics based on rocks of any age. PMID- 29577550 TI - Single and multiple dose evaluation of a novel MetAP2 inhibitor: Results of a randomized, double-blind, placebo-controlled clinical trial. AB - AIMS: Methionine aminopeptidase 2 (MetAP2) inhibition has been shown to result in significant weight loss and improved glucose control. This Phase 1 clinical trial assessed the safety and tolerability, pharmacokinetics and preliminary efficacy of a novel MetAP2 inhibitor, ZGN-1061. METHODS: This clinical trial included a single ascending dose (SAD) phase in healthy subjects (BMI, 23 to <30 kg/m2 ) and a multiple ascending dose (MAD) phase in otherwise healthy subjects (BMI, 27 to 40 kg/m2 ). SAD phase doses, administered subcutaneously (SC), were 0.2, 0.6, 1.2, 2.4, 3.6 and 4.8 mg and the MAD phase evaluated doses of 0.2, 0.6 and 1.8 mg twice weekly SC for 4 weeks. RESULTS: The SAD phase included 39 subjects (ZGN 1061, N = 28; placebo, N = 11); 90% were male and BMI was 26.4 kg/m2 . ZGN-1061 was well tolerated across all doses, with the most frequent adverse events being mild headache and procedural-related irritation. There were no severe or serious adverse events. All doses of ZGN-1061 were rapidly absorbed and cleared, resulting in short duration of exposure that is anticipated to minimize potential off-drug target risks. The MAD phase included 29 subjects (ZGN-1061, N = 22; placebo, N = 7); 76% were male and BMI was 33.5 kg/m2 . Safety observations were consistent with SAD findings. Efficacy measures in the MAD phase indicated trends for weight change (-1.5 kg total ZGN-1061 vs -0.2 kg placebo) and other biomarker changes. CONCLUSIONS: ZGN-1061 was well tolerated with no safety signals in all doses tested. In addition, the desired pharmacokinetic profile and preliminary efficacy observations with ZGN-1061 support evaluation in larger and longer clinical trials. PMID- 29577551 TI - Edge fires drive the shape and stability of tropical forests. AB - In tropical regions, fires propagate readily in grasslands but typically consume only edges of forest patches. Thus, forest patches grow due to tree propagation and shrink by fires in surrounding grasslands. The interplay between these competing edge effects is unknown, but critical in determining the shape and stability of individual forest patches, as well the landscape-level spatial distribution and stability of forests. We analyze high-resolution remote-sensing data from protected Brazilian Cerrado areas and find that forest shapes obey a robust perimeter-area scaling relation across climatic zones. We explain this scaling by introducing a heterogeneous fire propagation model of tropical forest grassland ecotones. Deviations from this perimeter-area relation determine the stability of individual forest patches. At a larger scale, our model predicts that the relative rates of tree growth due to propagative expansion and long distance seed dispersal determine whether collapse of regional-scale tree cover is continuous or discontinuous as fire frequency changes.

AB - The impact of adolescent substance abuse is widespread and significantly compromises the psychosocial well-being of those closest to the adolescent. This is evidentially so for parents who are required to cope with the adolescent's misconduct. Using an interpretative phenomenological methodology, this article describes mothers' experiences of living with an adolescent who is dependent on drugs. Specifically, the article explores the mothers' accounts of the pernicious behaviours that the adolescents engage(d) in during their drug abuse period. Qualitative 1:1 interviews revealed two common forms of adolescent misconduct that the mothers had to contend with which were 'belligerent attitudes and conducts' and 'pilfering behaviours'. The mothers further reported that the adolescents' behaviours negatively impacted on the mother-adolescent relationship, producing feelings of mistrust and a lack of trust. The findings contribute to the sparse literature on parents' experiences and thus hold implications for research and practice. Understanding the challenges that mothers contend with when adolescents engage in problematic drug use is important for the development of support interventions to help parents cope effectively. Further implications are presented in the article.

AB - Statins are widely prescribed, yet statin muscle pain limits their use, leading to increased cardiovascular risk. No validated therapy for statin muscle pain exists. The goal of the study was to assess whether metformin was associated with reduced muscle pain. A secondary analysis of data from the ACCORD trial was performed. An ACCORD sub-study assessed patients for muscle cramps and leg/calve pain while walking, typical non-severe statin muscle pain symptoms. We compared muscle pain between patients using a statin (n = 445) or both a statin and metformin (n = 869) at baseline. Overall patient characteristics were balanced between groups. Unadjusted analysis showed fewer reports of muscle cramps (35%) and leg/calve pain while walking (40%) with statins and metformin compared to statin only (muscle cramps, 42%; leg/calve pain while walking, 47%). Multivariable regression demonstrated a 22% odds reduction for muscle cramps (P = 0.049) and a 29% odds reduction for leg/calve pain while walking (P = 0.01). Metformin appears to reduce the risk of non-severe statin muscle pain and additional research is needed to confirm the findings and assess metformin's impact on statin adherence and related cardiovascular outcomes.

PMID- 29577555 TI - Transanal endoscopic surgery is effective and safe after endoscopic polypectomy of potentially malignant rectal polyps with questionable margins. AB - AIM: To determine the percentage of residual lesion observed in the pathology study of transanal endoscopic surgery (TEM) specimens after endoscopic polypectomy of malignant rectal polyps with questionable margins, and the need for further surgery. Secondary aims: to determine the morbidity and mortality associated with this procedure and to identify the percentage of recurrence after excision by TEM. METHODS: Observational study with prospective data collection of all patients undergoing TEM after endoscopic polypectomy for malignant rectal polyps or non-invasive high-grade neoplasia, from January 2004 to December 2016. An en bloc full-thickness wall excision of the scar was performed. Variables recorded: histology of TEM specimen, 30-day morbidity and mortality according to the Clavien-Dindo classification, need for salvage surgery and recurrence. RESULTS: Fifty out of 690 patients undergoing TEM during the study period (36 adenocarcinomas, five non-invasive high-grade neoplasias and 9 neuroendocrine tumors) were included. Post-surgery histology showed residual lesion in 21 (42%) patients: 7 neuroendocrine tumors, 10 adenomas and 4 adenocarcinomas (two pT1, one pT2 and one pT3). The pT2 and pT3 patients (4%) underwent salvage surgery. No recurrence was observed, and mean follow-up was 29.1A +/- 21.6 months. The 30-day morbidity rate was 14%, but 4/7 with Clavien-Dindo grade I. CONCLUSIONS: After endoscopic polypectomy of malignant rectal polyps with questionable margins, the presence of residual lesion in the pathology study of transanal resection specimens is high. TEM with full-thickness resection of these lesions is an appropriate treatment, allowing disease control and achieving minimal morbidity. PMID- 29577556 TI - The effect of increasing body mass index on laparoscopic surgery for colon and rectal cancer. AB - AIM: Obesity is common in Western countries and its prevalence is increasing. Colorectal cancer is common, and surgery for colorectal cancer is technically more challenging in obese patients. Laparoscopic surgery for colon cancer has been shown to be oncologically equivalent, with improved short- term outcomes. Laparoscopic surgery for rectal cancer has proven technically challenging, and recent results have raised concerns about oncological equivalence. Our aim was to evaluate the effect of body mass index (BMI) on the clinical and oncological outcomes of surgery for colorectal cancer, including the rate at which laparoscopic surgery is attempted and the rate at which laparoscopic surgery is converted to open surgery. METHOD: A retrospective analysis of prospectively collected data from two tertiary institutions was performed. Data were obtained from the Cabrini Monash University colorectal neoplasia database for patients having surgical resection for colon and rectal cancers between 1 January 2010 and 30 June 2015. Surgical and medical complications, tumour recurrence and overall survival and laparoscopic surgery and conversion rates were investigated. RESULTS: This large case series of 1464 patients undergoing elective surgery for colorectal cancer has demonstrated that an elevated BMI is associated with a lower likelihood of attempting laparoscopic surgery and a higher conversion rate to open surgery when laparoscopy is attempted. Conversion was 1.9 times more likely in obese patients with colon cancer and 4.1 times more likely in obese patients with rectal cancer. The critical BMI for colon cancer patients was > 35 kg/m2 , and for rectal cancer patients > 30 kg/m2 . Obesity is also associated with increased rates of surgical complications, including anastomotic leakage and wound complications. Pathological parameters, tumour recurrence and survival were not affected by elevated BMI. CONCLUSION: In the surgical management of colorectal cancer, obesity is associated with a lower likelihood of laparoscopic surgery being attempted, a higher likelihood of conversion to open surgery when laparoscopic surgery is attempted, and a higher rate of surgical complications. PMID- 29577557 TI - Myeloperoxidase, superoxide dismutase-3, cardiometabolic risk factors, and distal sensorimotor polyneuropathy: The KORA F4/FF4 study. AB - BACKGROUND: Oxidative stress has been proposed as important pathomechanism of cardiometabolic diseases and distal sensorimotor polyneuropathy (DSPN). However, the relevance of biomarkers of oxidative stress has not been investigated in this context. Therefore, this study aimed to assess the association of the prooxidant myeloperoxidase (MPO) and the antioxidant extracellular superoxide dismutase (SOD3) with cardiometabolic risk factors and with prevalence and incidence of DSPN. METHODS: Cross-sectional analyses comprised 1069 participants (40.3% with prediabetes and 20.5% with type 2 diabetes) of the population-based Cooperative Health Research in the Region of Augsburg (KORA) F4 study (2006-2008), 181 of whom had DSPN at baseline. Prospective analyses included 524 individuals without DSPN at baseline who also participated in the KORA FF4 study (2013-2014), 132 of whom developed DSPN during the 6.5-year follow-up. Serum MPO and SOD3 were measured by ELISA, and their association with cardiometabolic risk factors and DSPN were estimated by using linear and logistic regression analyses. RESULTS: Higher MPO and SOD levels showed multiple positive associations with cardiometabolic risk factors including age, indices of obesity, insulin resistance, serum lipids, renal dysfunction, and biomarkers of inflammation. Higher MPO levels were associated with prevalent DSPN (fully adjusted OR 1.38 [95% CI 1.10; 1.72] per doubling of MPO). Higher baseline SOD3 levels were related to incident DSPN (age and sex-adjusted OR 2.14 [1.02; 4.48] per doubling of SOD3), which was partially explained by cardiometabolic risk factors. CONCLUSIONS: Systemic levels of both pro- and antioxidant enzymes appear involved in cardiometabolic risk and development of DSPN. PMID- 29577558 TI - A systematic review and meta-analysis comparing adverse events and functional outcomes of different pouch designs after restorative proctocolectomy. AB - AIM: There is no consensus as to which ileoanal pouch design provides better outcomes after restorative proctocolectomy. This study compares different pouch designs. METHOD: A systematic review of the literature was performed. A random effects meta-analytical model was used to compare adverse events and functional outcome. RESULTS: Thirty comparative studies comparing J, W, S and K pouch designs were included. No significant differences were identified between the different pouch designs with regard to anastomotic dehiscence, anastomotic stricture, pelvic sepsis, wound infection, pouch fistula, pouch ischaemia, perioperative haemorrhage, small bowel obstruction, pouchitis and sexual dysfunction. The W and K designs resulted in fewer cases of pouch failure compared with the J and S designs. J pouch construction resulted in a smaller maximum pouch volume compared with W and K pouches. Stool frequency per 24 h and during daytime was higher following a J pouch than W, S or K constructions. The J design resulted in increased faecal urgency and seepage during daytime compared with the K design. The use of protective pads during daytime and night-time was greater with a J pouch compared to S or K. The use of antidiarrhoeal medication was greater after a J reservoir than a W reservoir. Difficulty in pouch evacuation requiring intubation was higher with an S pouch than with W or J pouches. CONCLUSION: Despite its ease of construction and comparable complication rates, the J pouch is associated with higher pouch failure rates and worse function. Patient characteristics, technical factors and surgical expertise should be considered when choosing pouch design. PMID- 29577559 TI - Tracing the fate of steroids through a hypersaline microbial mat (Kiritimati, Kiribati/Central Pacific). AB - Eukaryotic steranes are typically absent or occur in very low concentrations in Precambrian sedimentary rocks. However, it is as yet unclear whether this may reflect low source inputs or a preservational bias. For instance, it has been proposed that eukaryotic lipids were profoundly degraded in benthic microbial mats that were ubiquitous prior to the advent of vertical bioturbation in the Cambrian ("mat-seal effect"). It is therefore important to test the microbial turnover and degradation of eukaryotic steroids in real-world microbial mats. Here we assessed steroid inventories in different layers of a microbial mat from a hypersaline lake on Kiritimati (Central Pacific). Various eukaryote-derived C27 -C30 steroids were detected in all mat layers. These compounds most likely entered the mat system as unsaturated sterols from the water column or the topmost mat, and were progressively altered during burial in the deeper, anoxic mat layers over c. 103 years. This is reflected by increasing proportions of saturated sterols and sterenes, as well as the presence of thiosteranes in certain horizons. Sterol alteration can partly be assigned to microbial transformation but is also due to chemical reactions promoted by the reducing environment in the deeper mat layers. Notably, however, compounds with a sterane skeleton were similarly abundant in all mat layers and their absolute concentrations did not show any systematic decrease. The observed decrease of steroid/hopanoid ratios with depth may thus rather indicate a progressive "dilution" by lipids derived from heterotrophic bacteria. Further, pyrolysis revealed that steroids, in contrast to hopanoids, were not sequestered into non extractable organic matter. This may lead to a preservational bias against steroids during later stages of burial. Taken together, steroid preservation in the microbial mat is not only controlled by heterotrophic degradation, but rather reflects a complex interplay of taphonomic processes. PMID- 29577560 TI - Prevalence and severity of nonalcoholic fatty liver disease by transient elastography: Genetic and metabolic risk factors in a general population. AB - BACKGROUND & AIMS: The worldwide spread of obesity is leading to a dramatic increase in the prevalence of nonalcoholic fatty liver disease (NAFLD) and its complications. We aimed to evaluate both prevalence and factors associated with NAFLD in a general population in a Mediterranean area. METHODS: We considered 890 consecutive individuals included in the community-based ABCD (Alimentazione, Benessere Cardiovascolare e Diabete) study (ISRCTN15840340). Controlled attenuation parameter (CAP) and liver stiffness measurement (LSM) were measured with FibroScan. Participants were genotyped for PNPLA3 rs738409 and TM6SF2 rs58542926 variants. RESULTS: The prevalence of NAFLD in the cohort was 48%. NAFLD participants exhibited elevated LSM values, suggesting advanced fibrosis (6.5% of cases). Both NAFLD and advanced fibrosis were independently associated with traditional risk factors (NAFLD: age >50 years, obesity, hypertension, elevated ALT and low HDL-cholesterol serum concentrations. Advanced fibrosis: IFG/diabetes, elevated ALT serum concentrations). A high prevalence (>60%) of NAFLD was found in obese people, while it varied widely in non-obese people according to the presence of metabolic risk factors. PNPLA3 G variant (OR = 1.33, 95% C.I. = 1.01-1.8; P < .05) was independently associated with NAFLD. Prevalence of advanced fibrosis (high LSM values) ranged from 3.4% (no risk factors) to 60% (presence of all risk factors). TM6SF2 T variant (OR = 3.06, 95% C.I. = 1.08 8.65, P < .05) was independently associated with advanced fibrosis (high LSM values). CONCLUSIONS: In a cohort of a general population, the prevalence of NAFLD was very high, and among NAFLD patients a significant proportion had advanced fibrosis (high LSM values). Apart from traditional risk factors, genetic factors may have a significant role that needs to be further investigated.

PMID- 29577562 TI - Dermatological manifestations in hemodialysis patients in Iran: A systematic review and meta-analysis. AB - BACKGROUND: Dermatologic complications are common in patients with end-stage renal disease and also have a high diversity. OBJECTIVES: This meta-analysis reviews prevalence of dermatological manifestations among hemodialysis patients in Iran. MATERIALS AND METHODS: Using PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS as the main international electronic data sources, and Iran-Medex, Irandoc, and Scientific Information Database, as the main domestic databases with systematic search capability, we systematically searched surveys, papers, and reports on the prevalence of dermatological manifestations (until February 2016). Heterogeneity of reported prevalence's between studies was assessed using the Q test; overall prevalence of dermatological manifestations was estimated using random-effect meta-analysis model. RESULTS: We found 1229 records; from them, a total of eight studies comprising 917 hemodialysis patients were included. In all of studies, skin discoloration, pruritus and xerosis have the highest prevalence. According to random-effect meta-analysis model, the pooled prevalence of skin discoloration, pruritus, ecchymosis, xerosis, and half-and-half nail in hemodialysis patients were 48.03% (95% CI: 45.09-51.01), 52.85% (95%CI: 49.23-56.47), 19.88 (95% CI: 17.57-22.19), 51.14% (95% CI: 48.25-54.02), and 18.50% (95% CI: 16.0-21.0), respectively. CONCLUSIONS: his study shows that the prevalence of dermatological manifestations seems high among the hemodialysis patients in Iran, and skin discoloration, pruritus, and xerosis are more common.

PMID- 29577563 TI - Cohort study with 4-year follow-up of myopia and refractive parameters in primary schoolchildren in Baoshan District, Shanghai. AB - IMPORTANCE: Cohort studies could not only reveal associations between change of refractive components and onset/progression of myopia, but also risk factors, which is important for understanding mechanism and providing strategies. BACKGROUND: Prevalence of myopia is high in Shanghai, being reported to be 52.2% in children aged 10 years old. DESIGN: Cohort study. PARTICIPANTS: A total of 1856 students from six randomly selected primary schools in Baoshan District, Shanghai. METHODS: Children underwent comprehensive ocular measurement, including axial length (AL), corneal curvature radius and cycloplegic auto-refraction. Questionnaires about eye usage time were collected. Grade 1 students were followed for 4 years, and grade 2 and 3 students for 2 years. MAIN OUTCOME MEASURES: (i) Change of spherical equivalent (SE) and AL and (ii) risk factors for progression and incidence of myopia. RESULTS: The average 2-year progress of SE was 0.91D, 0.91D and 1.11D for grade 1, 2 and 3, respectively, and the average elongation of AL was 0.70 mm, 0.64 mm and 0.71 mm, respectively. Only parental myopia, but not near work time, near work diopter time, outdoor activity time or attending tutoring classes, was associated with myopia incidence and progression in the present population. Using baseline SE could be a simple and effective indicator for myopia prediction. CONCLUSIONS AND RELEVANCE: Incidence and progression of myopia is relatively high in schoolchildren in Shanghai compared with children of Western countries, East Asia and other parts of China. Effective strategies to control myopia prevalence are in urgent need.

PMID- 29577566 TI - OsPK2 encodes a plastidic pyruvate kinase involved in rice endosperm starch synthesis, compound granule formation and grain filling. AB - Starch is the main form of energy storage in higher plants. Although several enzymes and regulators of starch biosynthesis have been defined, the complete molecular machinery remains largely unknown. Screening for irregularities in endosperm formation in rice represents valuable prospect for studying starch synthesis pathway. Here, we identified a novel rice white-core endosperm and defective grain filling mutant, ospk2, which displays significantly lower grain weight, decreased starch content and alteration of starch physicochemical properties when compared to wild-type grains. The normal starch compound granules were drastically reduced and more single granules filled the endosperm cells of ospk2. Meanwhile, the germination rate of ospk2 seeds after 1-year storage was observably reduced compared with wild-type. Map-based cloning of OsPK2 indicated that it encodes a pyruvate kinase (PK, ATP: pyruvate 2-O-phosphotransferase, EC 2.7.1.40), which catalyses an irreversible step of glycolysis. OsPK2 has a constitutive expression in rice and its protein localizes in chloroplasts. Enzyme assay showed that the protein product from expressed OsPK2 and the crude protein extracted from tissues of wild-type exhibits strong PK activity; however, the mutant presented reduced protein activity. OsPK2 (PKpalpha1) and three other putative rice plastidic isozymes, PKpalpha2, PKpbeta1 and PKpbeta2, can interact to form heteromer. Moreover, the mutation leads to multiple metabolic disorders. Altogether, these results denote new insights into the role of OsPK2 in plant seed development, especially in starch synthesis, compound granules formation and grain filling, which would be useful for genetic improvement of high yield and rice grain quality.

AB - Low adherence to anti-hypertensive medications contributes to worse outcomes. The authors conducted a secondary data analysis to examine the effects of a health coaching intervention on medication adherence and blood pressure (BP), and to explore whether changes in medication adherence over time were associated with changes in BP longitudinally in 477 patients with hypertension. Data regarding medication adherence and BP were collected at baseline, 6, 12, 18, and 24 months. The intervention resulted in increases in medication adherence (5.75->5.94, P = .04) and decreases in diastolic BP (81.6->76.1 mm Hg, P < .001) over time. The changes in medication adherence were associated with reductions in diastolic BP longitudinally (P = .047). Patients with low medication adherence at baseline had significantly greater improvement in medication adherence and BP over time than those with high medication adherence. The intervention demonstrated improvements in medication adherence and diastolic BP and offers promise as a clinically applicable intervention in rural primary care. PMID- 29577575 TI - One-year clinical outcomes of locking taper Equator attachments retaining mandibular overdentures to narrow diameter implants. AB - BACKGROUND: Narrow diameter implants (NDI) are recommended to retain mandibular overdentures (MOs) in cases of limited bone thickness. It is necessary to evaluate the clinical behavior of NDI as MO retainers connected to a new screwless locking taper abutments, their predictability and maintenance problems. OBJECTIVES: To evaluate the peri-implant tissue behavior around NDI and the performance of locking taper stud abutments as MO retainers. METHODOLOGY: Thirty patients (average age of 67.5 years) received 2 NDI implants (2.9 * 10 mm) loaded after 12 weeks using Equator stud attachments. The plaque index (PI), calculus index (CI), gingival index (GI), probing depth (PD), bleeding on probing (BOP), and implant stability quotient (ISQ) were monitored during osseointegration at 0, 4, 8, and 12 weeks and postloading at 24, 48, and 60 weeks. The marginal bone level (MBL) and bone level changes (BLC) were determined at baseline and 60 weeks. RESULTS: The cumulative success rate was 83.3%. The PI oscillated in the first 24 weeks and decreased from 48 weeks onward, while the CI score showed significantly higher values at week 8 (22%). The GI also peaked at week 8 (18.6%) and decreased from week 12 onward. The PD decreased gradually over time, but no significant differences were found between weeks 8 and 12. The ISQ decreased significantly between 0 and 12 weeks. After MO loading, the ISQ values increased linearly and significantly between 12 and 24, 24 and 48, and 48 and 60 weeks and reached values similar to the primary stability after 60 weeks [56.1(42.0-65.3)]. No significant MBL was observed at 60 weeks, with an average BLC of -0.06 +/- 0.64 mm. CONCLUSION: NDI connected to locking taper Equator attachments showed a stable clinical behavior as an MO retainer for edentulous patients with clinical mandibular atrophy. PMID- 29577576 TI - Self-assembled, ellipsoidal polymeric nanoparticles for intracellular delivery of therapeutics. AB - Nanoparticle shape has emerged as a key regulator of nanoparticle transport across physiological barriers, intracellular uptake, and biodistribution. We report a facile approach to synthesize ellipsoidal nanoparticles through self assembly of poly(glycerol sebacate)-co-poly(ethylene glycol) (PGS-co-PEG). The PGS-PEG nanoparticle system is highly tunable, and the semiaxis length of the nanoparticles can be modulated by changing PGS-PEG molar ratio and incorporating therapeutics. As both PGS and PEG are highly biocompatible, the PGS-co-PEG nanoparticles show high hemo-, immuno-, and cytocompatibility. Our data suggest that PGS-co-PEG nanoparticles have the potential for use in a wide range of biomedical applications including regenerative medicine, stem cell engineering, immune modulation, and cancer therapeutics.

AB - The carbon and nitrogen isotopic signatures of chloropigments and porphyrins from the sediments of redox-stratified lakes and marine basins reveal details of past biogeochemical nutrient cycling. Such interpretations are strengthened by modern calibration studies, and here, we report on the C and N isotopic composition of pigments and nutrients in the water column and surface sediment of redox stratified Fayetteville Green Lake (FGL; New York). We also report delta13 C and delta15 N values for pyropheophytin a (Pphe a) and bacteriochlorophyll e (Bchl e) deposited in the Black Sea during its transition to a redox-stratified basin ca. 7.8 ka. We propose a model for evolving nutrient cycling in the Black Sea from 7.8 to 6.4 ka, informed by the new pigment data from FGL. The seasonal study of water column nutrients and pigments at FGL revealed population dynamics in surface and deep waters that were also captured in the sediments. Biomass was greatest near the chemocline, where cyanobacteria, purple sulfur bacteria (PSB), and green sulfur bacteria (GSB) had seasonally variable populations. Bulk organic matter in the surface sediment, however, was derived mainly from the oxygenated surface waters. Surface sediment pigment delta13 C and delta15 N values indicate intact chlorophyll a (Chl a) was derived from near the chemocline, but its degradation product pheophytin a (Phe a) was derived primarily from surface waters. Bacteriopheophytin a (Bphe a) and Bchl e in the sediments came from chemocline populations of PSB and GSB, respectively. The distinctive delta13 C and delta15 N values for Chl a, Phe a, and Bphe a in the surface sediment are inputs to an isotopic mixing model that shows their decomposition to a common porphyrin derivative can produce non-specific sedimentary isotope signatures. This model serves as a caveat for paleobiogeochemical interpretations in basins that had diverse populations near a shallow chemocline. PMID- 29577578 TI - Quantification of beam steering with an ionization chamber array. AB - Routine quality assurance for linear accelerators (linacs) usually involves verification of beam steering with a water scanning system. We established a beam steering procedure that uses a 2D ionization chamber array (ICA) and verified the equivalence of beam symmetry between the ICA and a water scanning system. The ICA calibration accuracy, reproducibility and stability were evaluated and the uncertainty in the measurement of beam symmetry due to the array calibration was examined. Forty-five photon beams and 80 electron beams across 7 Varian C-series and 4 TrueBeam linacs were steered in the radial and transverse directions using an ICA. After beam steering, profiles were re-measured using the ICA and in-water using a 3D Scanner (3DS). Beam symmetries measured with the ICA and 3DS were compared by (a) calculating the difference in point-by-point symmetry, (b) plotting the histogram distribution of the symmetry differences, and (c) comparing ICA and 3DS differences with their respective Varian symmetry protocol analysis. Array calibrations from five different occurrences (2012 to 2016) over six different beams reproduced within 0.5%. The uncertainty in beam symmetry was less than 0.5% due to the uncertainties in the array calibration. After all beams were steered using the ICA, the point-by-point symmetry differences between ICA and 3DS at the off-axis positions of 20% and 80% of field size for all beam profiles indicated that 95% of point-by-point symmetry comparisons agreed within 0.7%, and 100% agreed within 1.0%; after steering with the ICA 97.8% of photon beam profiles (88 of 90) and 97.5% of electron beam profiles (156 of 160) had symmetry within 1% when measured with the 3DS. All photon and electron beam profiles had symmetry within 1.1% and 1.2%, respectively, for profiles measured with the 3DS. Our data demonstrate that a calibrated ICA can be used to steer photon and electron beams achieving beam symmetry within 1% when re-measured with a 3D water scanning system. PMID- 29577579 TI - Hepatic and cardiac beneficial effects of a long-acting Fc-apelin fusion protein in diet-induced obese mice. AB - BACKGROUND: Apelin is a peptide ligand of the G-protein-coupled receptor APJ and exhibits anti-diabetes and anti-heart failure activities. However, short serum half-life of the apelin peptide limits its potential clinical applications. This study aimed to develop a long-acting apelin analog. METHODS: To extend apelin's in vivo half-life, we made a recombinant protein by fusing the IgG Fc fragment to apelin-13 (Fc-apelin-13), conducted pharmacokinetics studies in mice, and determined in vitro biological activities in suppressing cyclic adenosine monophosphate and activating extracellular signal-regulated kinase signalling by reporter assays. We investigated the effects of Fc-apelin-13 on food intake, body weight, fasting blood glucose and insulin levels, glucose tolerance test, hepatic steatosis, and cardiac function and fibrosis by subcutaneous administration of Fc apelin-13 in diet-induced obese mice for 4 weeks. RESULTS: The estimated half life of Fc-apelin-13 in blood was approximately 33 hours. Reporter assays showed that Fc-apelin-13 was active in suppressing cyclic adenosine monophosphate response element and activating serum response element activities. Four weeks of Fc-apelin-13 treatment in obese mice did not affect food intake and body weight, but resulted in a significant improvement of glucose tolerance, and a decrease in hepatic steatosis and fibrosis, as well as in serum alanine transaminase levels. Moreover, cardiac stroke volume and output were increased and cardiac fibrosis was decreased in the treated mice. CONCLUSIONS: Fc-apelin-13 fusion protein has an extended in vivo half-life and exerts multiple benefits on obese mice with respect to the improvement of glucose disposal, amelioration of liver steatosis and heart fibrosis, and increase of cardiac output. Hence, Fc-apelin-13 is potentially a therapeutic for obesity-associated disease conditions. PMID- 29577580 TI - Development of a new 3-DOF parallel manipulator for minimally invasive surgery. AB - This article proposes a novel dexterous endoscopic parallel manipulator for minimally invasive surgery. The proposed manipulator has 3 degrees of freedom (3 DOF), which consist of two rotational DOFs and one translational DOF (2R1T DOFs). The manipulator consists of 3 limbs exhibiting identical kinematic structure. Each limb contains an active prismatic joint followed by 2 consecutive passive universal joints. The proposed manipulator has a unique arrangement of its joints' axes. This unique arrangement permits large bending angles, +/-90 degrees in any direction, and a workspace almost free from interior singularities. These advantages allow the proposed manipulator to outperforms existing surgical manipulators. However, this unique arrangement makes the analysis of the robot extremely difficult. Therefore, a geometrical/analytical approach is used to facilitate its singularity analysis. Construction of the virtual prototype is accomplished using ADAMS software to validate the proposed manipulator and its bending capability. A closed-form solution for inverse kinematics is obtained analytically. Also, the forward kinematics solution is obtained numerically. Moreover, evaluation of the workspace is achieved using motion/force transmissibility indices. A practical experiment has been performed using a scaling technique and PID controller.

AB - Interferon (IFN)-free, direct-acting antiviral (DAA) therapy agents provide a safe and efficacious treatment for liver transplant recipients with recurrent hepatitis C virus (HCV) infection. The aim of this study is to evaluate the impact of HCV eradication on the metabolic factors in liver transplant recipients. We completed a retrospective single-center study on HCV-related liver transplant recipients treated with IFN-free DAAs including both treatment-naive and treatment-experienced patients. IFN-free DAAs impact on the metabolic profile were assessed at baseline and sustained virological response (SVR) between 24 and 48 weeks. In total, 91 liver transplant recipients with recurrent HCV infection received IFN-free DAA treatment, 62 patients had IFN-based treatment failure, and 29 were treatment-naive, of whom 87 (96%) achieved SVR. Eradication of recurrent HCV infection was associated with reduction in the treatment of diabetes and hypertension by 38% and 22% from the baseline respectively. Hemoglobin A1c (HbA1c) levels declined from mean 35.5 +/- 4.3 mmol/mol to 33.3 +/-3.6 mmol/mol at 44 weeks posttreatment (P = 0.03). Total cholesterol levels increased from 3.8 +/- 0.9 mmol/L to 4.9 +/- 0.9 mmol/L at 41 weeks posttreatment (P < 0.0001), reflecting a significant increase in serum low-density lipoprotein (LDL) levels (2.0 +/- 0.8 to 2.9 +/- 0.8; P < 0.0001). Estimated glomerular filtration rate (eGFR) levels increased from 64.9 +/- 20 mL/minute to 69.6 +/- 20 mL/minute at 24 weeks posttreatment (P = 0.0004). Glucose, lipid profile, and eGFR changes were independent of weight changes and immunosuppression dosage and trough levels. In conclusion, eradication of recurrent HCV infection by DAA therapy has beneficial impacts on glucose metabolism and renal profile and reverses the hypolipidemic effect of HCV in liver transplant recipients. These extrahepatic effects of DAA therapy need to be validated by larger prospective studies.

PMID- 29577582 TI - The genetic component of human longevity: New insights from the analysis of pathway-based SNP-SNP interactions. AB - In human longevity studies, single nucleotide polymorphism (SNP) analysis identified a large number of genetic variants with small effects, yet not easily replicable in different populations. New insights may come from the combined analysis of different SNPs, especially when grouped by metabolic pathway. We applied this approach to study the joint effect on longevity of SNPs belonging to three candidate pathways, the insulin/insulin-like growth factor signalling (IIS), DNA repair and pro/antioxidant. We analysed data from 1,058 tagging SNPs in 140 genes, collected in 1825 subjects (1,089 unrelated nonagenarians from the Danish 1905 Birth Cohort Study and 736 Danish controls aged 46-55 years) for evaluating synergic interactions by SNPsyn. Synergies were further tested by the multidimensional reduction (MDR) approach, both intra- and interpathways. The best combinations (FDR<0.0001) resulted those encompassing IGF1R-rs12437963 and PTPN1-rs6067484, TP53-rs2078486 and ERCC2-rs50871, TXNRD1-rs17202060 and TP53 rs2078486, the latter two supporting a central role of TP53 in mediating the concerted activation of the DNA repair and pro-antioxidant pathways in human longevity. Results were consistently replicated with both approaches, as well as a significant effect on longevity was found for the GHSR gene, which also interacts with partners belonging to both IIS and DNA repair pathways (PAPPA, PTPN1, PARK7, MRE11A). The combination GHSR-MREA11, positively associated with longevity by MDR, was further found influencing longitudinal survival in nonagenarian females (p = .026). Results here presented highlight the validity of SNP-SNP interactions analyses for investigating the genetics of human longevity, confirming previously identified markers but also pointing to novel genes as central nodes of additional networks involved in human longevity.

AB - Carbonate apatite (CO3 Ap) blocks have attracted considerable attention as an artificial bone substitute material because CO3 Ap is a component of and shares properties with bone, including high osteoconductivity and replacement by bone similar to autografts. In this study, we fabricated an interconnected porous CO3 Ap block using alpha-tricalcium phosphate (TCP) spheres and evaluated the tissue response to this material in a rabbit tibial bone defect model. Interconnected porous alpha-TCP, the precursor of interconnected porous CO3 Ap, could not be fabricated directly by sintering alpha-TCP spheres. It was therefore made via a setting reaction with alpha-TCP spheres, yielding interconnected porous calcium deficient hydroxyapatite that was subjected to heat treatment. Immersing the interconnected porous alpha-TCP in Na-CO3 -PO4 solution produced CO3 Ap, which retained the interconnected porous structure after the dissolution-precipitation reaction. The diametral tensile strength and porosity of the porous CO3 Ap were 1.8 +/- 0.4 MPa and 55% +/- 3.2%, respectively. Both porous and dense (control) CO3 Ap showed excellent tissue response and good osteoconductivity. At 4 weeks after surgery, approximately 15% +/- 4.9% of the tibial bone defect was filled with new bone when reconstruction was performed using porous CO3 Ap; this amount was five times greater than that obtained with dense CO3 Ap. At 12 weeks after surgery, for porous CO3 Ap, approximately 47% of the defect was filled with new bone as compared to 16% for dense CO3 Ap. Thus, the interconnected porous CO3 Ap block is a promising artificial bone substitute material for the treatment of bone defects caused by large fractures or bone tumor resection.

PMID- 29577585 TI - nNOS-CAPON interaction mediates amyloid-beta-induced neurotoxicity, especially in the early stages. AB - In neurons, increased protein-protein interactions between neuronal nitric oxide synthase (nNOS) and its carboxy-terminal PDZ ligand (CAPON) contribute to excitotoxicity and abnormal dendritic spine development, both of which are involved in the development of Alzheimer's disease. In models of Alzheimer's disease, increased nNOS-CAPON interaction was detected after treatment with amyloid-beta in vitro, and a similar change was found in the hippocampus of APP/PS1 mice (a transgenic mouse model of Alzheimer's disease), compared with age matched background mice in vivo. After blocking the nNOS-CAPON interaction, memory was rescued in 4-month-old APP/PS1 mice, and dendritic impairments were ameliorated both in vivo and in vitro. Furthermore, we demonstrated that S nitrosylation of Dexras1 and inhibition of the ERK-CREB-BDNF pathway might be downstream of the nNOS-CAPON interaction. PMID- 29577586 TI - In vivo efficacy and properties of semisolid formulations containing panthenol. AB - BACKGROUND: Panthenol is an active substance used in dermatology to protect the health of the skin, to treat defects in the morphology of the stratum corneum. In cosmetology, hydrating, softening, and barrier function of panthenol are utilized. Detailed studies evaluating the efficacy of panthenol in cosmetic and pharmaceutical semisolid formulations and establishing its optimum concentration are needed. OBJECTIVES: To investigate whether an addition of 5-13 wt% panthenol in o/w and w/o emulsions increases hydration and supports the barrier properties of the skin. Rheological properties and sensory analysis of prepared formulations are supplemented. METHODS: Noninvasive instrumental methods in vivo were used. The hydration and barrier effect of semisolid formulations on the skin were observed for 48 hour; testing was conducted on 40 women. The effect was compared with formulations without any content of panthenol. The rheological and organoleptic properties of the formulations were evaluated. RESULTS: After applying either form of the formulations containing 7-11 wt% of panthenol hydration of the skin increased, transepidermal water loss decreased. pH of the skin shifted toward neutral after application of tested formulations. The rheological properties of the formulations were influenced by the type of vehicle, the amount of panthenol, and temperature. Sensory evaluation of both semisolid forms revealed statistically significant differences in o/w formulations with regard to spreadability. CONCLUSIONS: The presence of panthenol in an o/w and w/o semisolid formulations significantly enhances skin barrier repair and hydration of the stratum corneum. Better vehicle for the active substance as regards hydration proved o/w formulations.

AB - In the present study, novel mesoporous bioactive glasses (MBGs) (15-x)CuO-xMgO 10P2 O5 -60SiO2 -10CaO-5ZnO (2.5 <= x <= 12.5, varying in steps of 2) are synthesized using the sol-gel technique. The structural phases of the glasses/glass ceramics were studied by XRD. The pH variation and simulated body fluids (SBF) studies demonstrated the in-vitro bioactivity of all the MBGs. MBGs possess surface area variation between 98.22 and 442.41 cm2 /g. The pore size of MBGs lies in the range of 5.8-8.8 nm. The cytotoxicity assays were conducted for MG63 human osteosarcoma cell line depicting non-toxic behavior of all MBGs at 7.8125 MUg/ml. In addition to this, the effect of the magnesium on the gene expression was also investigated using reverse transcription-polymerase chain reaction (RT-qPCR). The MBGs were loaded with the antibacterial (vancomycin/amoxicillin), anticancerous (doxorubicin), and analgesic (Iburofen) drugs. Ibuprofen and amoxicillin drugs were almost fully loaded in all the MBGs, whereas doxorubicin and vancomycin drugs illustrated variation in loading with decreasing copper content.

PMID- 29577589 TI - Correlation of infarct size with invasive hemodynamics in patients with ST elevation myocardial infarction. AB - OBJECTIVES: To identify invasive hemodynamic parameters that correlate with infarction size in patients with ST-elevation myocardial infarction (STEMI). BACKGROUND: Invasive hemodynamics obtained during primary percutaneous coronary intervention (PPCI) are predictive of mortality in STEMI, but which parameters correlate best with the size of the infarction are unknown. METHODS: This is a single-center study of 405 adult patients with STEMI who had left ventricular end diastolic pressure (LVEDP) measured during PPCI. Size of infarction was estimated by peak troponin I level and ejection fraction (LVEF) determined by echocardiography. RESULTS: The average (+/-SD) age was 61 +/- 14 years, TIMI STEMI risk score was 3.5 +/- 2.7 and Grace score was 157 +/- 42. Hemodynamic parameters that correlated best with EF were LVEDP (r = -0.40), PP (r = 0.24), and SBP/LVEDP ratio (r = 0.22) and with peak troponin were SBP/LVEDP ratio (r = 0.41), LVEDP (r = 0.31), and PP (r = -0.29). SBP/LVEDP (AUC = 0.76) and SBP (AUC = 0.77) had a stronger association with in-hospital mortality than did LVEDP (AUC = 0.66) or PP (AUC = 0.64). Door-to-balloon time did not affect the correlations between hemodynamic parameters and infarct size. CONCLUSIONS: In this sample of 405 patients undergoing PPCI, SBP/LVEDP ratio had the strongest correlation with peak troponin levels and LVEDP with EF, whereas SBP/LVEDP and SBP had a strong association with in-hospital mortality. These results suggest that measurement of LVEDP as well as SBP may help risk stratify patients during PPCI.

AB - Carbonaceous nanotubes (CTs) represent one of the most popular and effective carbon electrode materials for supercapacitors, but the electrochemistry performance of CTs is largely limited by their relatively low specific surface area, insufficient usage of intratube cavity, low content of heteroatom, and poor porosity. An emerging strategy for circumventing these issues is to design novel porous CT-based nanostructures. Herein, a spheres-in-tube nanostructure with hierarchical porosity is successfully engineered, by encapsulating heteroatom doping hollow carbon spheres into one carbonaceous nanotube (HCSs@CT). This intriguing nanoarchitecture integrates the merits of large specific surface area, good porosity, and high content of heteroatoms, which synergistically facilitates the transportation and exchange of ions and electrons. Accordingly, the as prepared HCSs@CTs possess outstanding performances as electrode materials of supercapacitors, including superior capacitance to that of CTs, HCSs, and their mixtures, coupled with excellent cycling life, demonstrating great potential for applications in energy storage. PMID- 29577591 TI - Effects of antigen removal on a porcine osteochondral xenograft for articular cartilage repair. AB - Given the limited availability of fresh osteochondral allografts and uncertainty regarding performance of decellularized allografts, this study was undertaken as part of an effort to develop an osteochondral xenograft for articular cartilage repair. The purpose was to evaluate a simple antigen removal procedure based mainly on treatment with SDS and nucleases. Histology demonstrated a preservation of collagenous structure and removal of most nuclei. Immunohistochemistry revealed the apparent retention of alpha-Gal within osteocyte lacunae unless the tissue underwent an additional alpha-galactosidase processing step. Cytoplasmic protein was completely removed as shown by Western blot. Quantitatively, the antigen removal protocol was found to extract approximately 90% of DNA from cartilage and bone, and it extracted over 80% of glycosaminoglycan from cartilage. Collagen content was not affected. Mechanical testing of cartilage and bone were performed separately, in addition to testing the cartilage-bone interface, and the main effect of antigen removal was an increase in cartilage hydraulic permeability. In vivo immunogenicity was assessed by subcutaneous implantation into DBA/1 J mice, and the response was typical of a foreign body rather than immune reaction. Thus, an osteochondral xenograft produced as described has the potential for further development into a treatment for osteochondral lesions in the human knee. (c) 2018 Wiley Periodicals, Inc.

AB - PURPOSE: The aim of this study was to investigate the intra-fractional patient motion using the ExacTrac system in LINAC-based stereotactic radiosurgery (SRS). METHOD: A retrospective analysis of 104 SRS patients with kilovoltage image guided setup (Brainlab ExacTrac) data was performed. Each patient was imaged pre treatment, and at two time points during treatment (1st and 2nd mid-treatment), and bony anatomy of the skull was used to establish setup error at each time point. The datasets included the translational and rotational setup error, as well as the time period between image acquisitions. After each image acquisition, the patient was repositioned using the calculated shift to correct the setup error. Only translational errors were corrected due to the absence of a 6D treatment table. Setup time and directional shift values were analyzed to determine correlation between shift magnitudes as well as time between acquisitions. RESULTS: The average magnitude translation was 0.64 +/- 0.59 mm, 0.79 +/- 0.45 mm, and 0.65 +/- 0.35 mm for the pre-treatment, 1st mid-treatment, and 2nd mid-treatment imaging time points. The average time from pre-treatment image acquisition to 1st mid-treatment image acquisition was 7.98 +/- 0.45 min, from 1st to 2nd mid-treatment image was 4.87 +/- 1.96 min. The greatest translation was 3.64 mm, occurring in the pre-treatment image. No patient had a 1st or 2nd mid-treatment image with greater than 2 mm magnitude shifts. CONCLUSION: There was no correlation between patient motion over time, in direction or magnitude, and duration of treatment. The imaging frequency could be reduced to decrease imaging dose and treatment time without significant changes in patient position. PMID- 29577593 TI - Isolation and enrichment of Ginkgo biloba extract by a continuous chromatography system. AB - In this study, an effective method was developed for the isolation and enrichment of Ginkgo biloba extract by continuous chromatography system. The adsorption and desorption ratio of flavonoids as main index, the best macroporous resin was screened out from six resins by static adsorption and desorption tests. At the same time the adsorption and desorption parameters were optimized by dynamic adsorption and desorption tests. Under optimal parameters, five operations consisting of loading, washing, desorbing, regenerating, and balancing were integrated across the continuous chromatography system for the purpose of refining 66 L of crude extract solution. The results were as follows, 198.22 g of Ginkgo biloba extracts was produced, which contained 65.83 g of flavonoids and 15.44 g of lactones. The content of flavonoids and lactones increased from 2.76 and 0.72% in the crude extract to 33.21 and 7.79%, with a recovery yield of 91.26 and 81.21%. Methodology validation showed that the proposed method had high stability and reproducibility. Compared with the traditional macroporous resin method, the proposed method had a short processing time and low solvent consumption. Our studies indicated that the newly developed method is an effective procedure for the isolation and enrichment of Ginkgo biloba extract. PMID- 29577594 TI - Butyrate Inhibits Indices of Colorectal Carcinogenesis via Enhancing alpha Ketoglutarate-Dependent DNA Demethylation of Mismatch Repair Genes. AB - SCOPE: Butyrate, the fermentation end product of gut microbiota in the colon, is known for its antitumor effects, but the mechanisms remained to be defined. alpha ketoglutarate (alpha-KG) mediates DNA demethylation and aberrant epigenetic modifications are associated with carcinogenesis. The objectives of this study are to evaluate the effects of butyrate on alpha-KG mediated epigenetic modification in colorectal adenocarcinoma HT-29 and Caco-2 cells. METHODS AND RESULTS: Butyrate suppressed proliferation, potentiated differentiation, and induced apoptosis in both HT-29 and Caco-2 cells, associated with enhanced expression of isocitrate dehydrogenase 1 (IDH1) and pyruvate dehydrogenase. Furthermore, butyrate upregulated acetyl-CoA and alpha-KG, concomitant with enhanced histone acetylation and DNA demethylation in the promoter of DNA mismatch repair (MMR) gene. Knocking down IDH1 abolished the positive effects of butyrate on CRC apoptosis and MMR protein expression, in conjunction with reduced alpha-KG content. Importantly, alpha-KG supplementation recovered the beneficial effects of butyrate in IDH1-deficient cells. CONCLUSION: In summary, butyrate inhibits indices of colorectal carcinogenesis in an alpha-KG-dependent manner. PMID- 29577595 TI - Comparison of different grafting materials for treatment of bone defect distal to the molar in canine. AB - BACKGROUND: The extraction of impacted mandibular 3rd molar is highly related to bone defect distal to the adjacent 2nd molar. PURPOSE: The aim of this study was to evaluate the effect of different grafting materials for the treatment of bone defect distal to the mandibular molar in canine model. MATERIALS AND METHODS: In 12 beagle dogs, bilateral mandibular 2nd and 3rd molars were extracted and entire mesial bone of the 2nd molar extracted socket was surgically removed. Twenty-four bone defects (4 mm width and 8 mm depth) were randomly assigned to 4 groups, and grafted using 1 of the following protocols: (1) group C: no graft; (2) group Ta: autogenous bone (AB); (3) group Tb: deproteinized bovine bone mineral (DBBM) with a collagen membrane (CM); and (4) group Tab: an equal mixture of AB/DBBM + CM. Quantitative imageology analyses using micro-CT and fluorescence microscopy, as well as qualitative analyses using histological and histomorphometric evaluations, were characterized at postoperative 12 weeks. Significant differences of all variables were tested by multivariate analysis (P < .05). RESULTS: The defect depth was significantly lower in groups Ta, Tb, and Tab (1.70, 1.97, and 1.61 mm, respectively; mean) than in the group C (3.66 mm, P < .01, all). Compared to the sites received DBBM/CM, sites grafted with AB or AB/DBBM exhibited significant greater and faster new bone formation (P < .01). The percentage of DBBM remnants area (%) was significantly higher in group Tb than in group Tab (10.43% and 1.13%, P < .01; mean). CONCLUSIONS: Our data suggested grafting AB alone, DBBM/CM, or AB/DBBM/CM resulted in similar periodontal parameters in canine. Furthermore, the AB could accelerate new bone regeneration and mineralization, and promote the biodegradation of DBBM. PMID- 29577596 TI - The role of plant size in the selection of glyphosate resistance in Sorghum halepense. AB - BACKGROUND: The effect of plant size (seedlings versus young plants versus adult plants) on the phenotypic level of glyphosate resistance and selection intensity (SI) in Sorghum halepense with and without a reduced glyphosate translocation resistance mechanism was evaluated. RESULTS: Resistance parameters [the 50% lethal dose (LD50 ) and the dose required to cause a 50% reduction in plant growth (GR50 )] in adult plants were notably higher than in seedlings regardless of the resistance status. However, under similar plant size increases, populations comprised of glyphosate-resistant (R) individuals showed higher survival and growth when glyphosate treated compared with glyphosate-susceptible (S) plants. An increase in SI was always evident with increasing glyphosate doses. However, the rate of increase in SI was higher under glyphosate selection of young R and S plants, followed by seedlings and adult R and S plants. However, in conditions of R seedlings coexisting with adult S plants under glyphosate treatment (1000-4000 g ha-1 ), selection against glyphosate resistance was observed. CONCLUSION: Any increase in size from the seedling stage of R plants translates into an amplification of resistance. Depending on the particular size combinations of spatially coexisting R and S plants, selection for glyphosate resistance may be faster, slower or even not evident.

AB - BACKGROUND: The acaricidal activity of Salvia lavandulifolia oil and its major components was evaluated using contact and vapor bioassays. Synergistic interactions among components contained in S. lavandulifolia oil were studied. RESULTS: The 50% lethal dose (LD50 ) of S. lavandulifolia oil was 3.66, 3.37, and 5.04 MUg cm-3 , respectively, in the vapor bioassay against Dermatophagoides farinae, Dermatophagoides pteronyssinus and Tyrophagus putrescentiae. The major components of S. lavandulifolia oil were (-)-camphor, camphene, 1,8-cineole, (+/ )-limonene, and alpha-pinene (79.11% combined). Several combinations of these components exhibited synergistic effects against D. farinae, D. pteronyssinus, and T. putrescentiae, particularly (-)-camphor, camphene, and alpha-pinene. (-) Camphor usually had synergistic interactive effects in the mixtures. For the vapor action, the mixture of (-)-camphor, camphene and alpha-pinene was the most potent combination against D. farinae (R = 2.34), D. pteronyssinus (R = 2.75), and T. putrescentiae (R = 2.30) when used at their naturally occurring ratio. CONCLUSION: This study is the first report on the acaricidal activity of S. lavandulifolia oil and the synergistic interactive effects of its components against D. farinae, D. pteronyssinus and T. putrescentiae. The oil may be an alternative tool for the control of synanthropic mites. (c) 2018 Society of Chemical Industry. PMID- 29577598 TI - Pressured HIV testing "in the name of love": a mixed methods analysis of pressured HIV testing among men who have sex with men in China. AB - INTRODUCTION: HIV testing has rapidly expanded into diverse, decentralized settings. While increasing accessibility to HIV testing is beneficial, it may lead to unintended consequences such as being pressured to test. We examined the frequency, correlates and contexts of pressured HIV testing among Chinese men who have sex with men (MSM) using mixed methods. METHODS: We conducted an online survey of MSM (N = 1044) in May 2017. Pressured HIV testing was defined as being forced to test for HIV. We conducted logistic regression analysis to determine the associations between pressured HIV testing and socio-demographic and sexual behavioural factors. Follow-up interviews (n = 17) were conducted with men who reported pressured testing and we analysed qualitative data using a thematic analysis approach. RESULTS: Ninety-six men (9.2%) reported experiencing pressure to test for HIV. Regular male sex partners were the most common source of pressure (61%, 59/96), and the most common form of pressure was a threat to end a relationship with the one who was being pressured (39%, 37/96). We found a higher risk of pressured testing in men who had only used HIV self-testing compared to men who had never self-tested (AOR 2.39 (95%CI: 1.38 to 4.14)). However, this relationship was only significant among men with low education (AOR 5.88 (95% CI: 1.92 to 17.99)) and not among men with high education (AOR 1.62 (95% CI: 0.85 to 3.10)). After pressured testing, about half of men subsequently tested for HIV (55%, 53/96) without pressure - none reported being diagnosed with HIV. Consistent with this finding, qualitative data suggest that perceptions of pressure existed on a continuum and depended on the relationship status of the one who pressured them. Although being pressured to test was accompanied by negative feelings, men who were pressured into testing often changed their attitude towards HIV testing, testing behaviours, sexual behaviours and relationship with the one who pressured them to test. CONCLUSION: Pressured HIV testing was reported among Chinese MSM, especially from men with low education levels and men who received HIV self-testing. However, in some circumstances, pressure to test helped MSM in several ways, challenging our understanding of the role of agency in the setting of HIV testing. PMID- 29577599 TI - Proteins Identified from Saliva and Salivary Glands of the Chinese Gall Aphid Schlechtendalia chinensis. AB - Aphid saliva plays an essential role in the interaction between aphids and their host plants. Several aphid salivary proteins have been identified but none from galling aphids. Here the salivary proteins from the Chinese gall aphid are analyzed, Schlechtendalia chinensis, via an LC-MS/MS analysis. A total of 31 proteins are identified directly from saliva collected via an artificial diet, and 141 proteins are identified from extracts derived from dissected salivary glands. Among these identified proteins, 17 are found in both collected saliva and dissected salivary glands. In comparison with salivary proteins from ten other free-living Hemipterans, the most striking feature of the salivary protein from S. chinensis is the existence of high proportion of proteins with binding activity, including DNA-, protein-, ATP-, and iron-binding proteins. These proteins maybe involved in gall formation. These results provide a framework for future research to elucidate the molecular basis for gall induction by galling aphids. PMID- 29577600 TI - Quantification of number of CD38 sites on bone marrow plasma cells in patients with light chain amyloidosis and smoldering multiple myeloma. AB - BACKGROUND: Recent approaches in multiple myeloma (MM) treatment have targeted CD38. As antigen expression levels on plasma cells (PCs) were demonstrated to affect response to monoclonal antibody (mAb) treatment, a precise characterization of PC phenotype is warranted. METHODS: Anti-CD38 mAb (isatuximab) was tested for antibody-dependent cellular cytotoxicity (ADCC) in MM cell lines. Quantification of the number of sites (NOS) of CD38 on bone marrow PCs and other immune cells obtained from light chain (AL) amyloidosis (n = 46) and smoldering multiple myeloma (SMM) patients (n = 19) was performed with two different quantitative flow cytometry (QFCM) applications. RESULTS: ADCC activity of isatuximab was observed in cell lines with >100 * 103 CD38-NOS only. The average PC CD38-NOS was 153 +/- 53 * 103 in AL amyloidosis and 138.7 +/- 53 * 103 in SMM patients. Eight (17%) AL amyloidosis and 4 (21%) SMM patients showed a PC CD38-NOS level <100 * 103 . In four AL amyloidosis and two SMM patients <10% of PCs had a CD38-NOS >=100 * 103 . The CD38-NOS identified on bone marrow lymphocytes, monocytes, and granulocytes was two log units below the CD38-NOS on PCs (P < 0.001). No significant differences in CD38-NOS expression levels on any of the analyzed PC subpopulations in AL amyloidosis and SMM patients were identified. CONCLUSION: Levels of CD38 expression affect the isatuximab-mediated ADCC in vitro. As PCs of patients with AL amyloidosis and SMM do not homogenously express high CD38 our data provide a rationale for assessment of CD38-NOS in patients with PC disorders prior to anti-CD38 treatment.

PMID- 29577601 TI - The effects of cobalt and chromium ions on transforming growth factor-beta patterns and mineralization in human osteoblast-like MG63 and SaOs-2 cells. AB - Bone homeostasis, the balance of bone formation and resorption is affected by numerous influences, such as, hormones, inflammation, mechanical load, and external stimuli. The transforming growth factor-beta (TGF-beta), which exists in three isoforms in humans, is a major factor in the maintenance of this balance by regulating osteoblast and osteoclast maturation, development, and function. In artificial joint replacements, release of particles or ions from arthroplasties may exert local effects on the periprosthetic tissue and modulate the expression of bone specific genes and functions. Therefore, the influence of cobalt (II) and chromium (III) ions on the expression levels of the three TGF-beta isoforms in human osteosarcoma cell lines MG63 and SaOs-2 was analyzed and the impact on mineralization was studied. The osteosarcoma cell lines expressed all three TGF beta isoforms, with TGF-beta1 being the most abundant isoform. A dose dependent reduction of all TGF-beta isoforms by Co2+ ions was observed, the strongest effect was found on TGF-beta2. The effect was lesser pronounced in SaOs-2 cells. However, the Cr3+ ions had no significant effect on the expression of all TGF beta isoforms. In contrast, Co2+ ions in a concentration range of 50-250 uM did not impair the mineralization, but Cr3+ exerted a strong inhibitory effect on the mineralization in a dose dependent fashion. These data suggest that the influence of cobalt ions on bone homeostasis may in part result from the inhibitory effect on the transcription of the bone regulating cytokines TGF-beta1-3 whereas the chromium ions affect the process of mineralization.

AB - Subcutaneous implantation of synthetic materials and biomedical devices often induces abnormal tissue healing - the foreign body reaction-which impairs their function. In particular, Interferon-gamma (IFN-gamma) is a critical endogenous mediator of inflammation and plays a key role in a wide variety of biological responses including tissue healing. However, the contribution of endogenous IFN gamma on different features of the foreign body response induced by synthetic implants regarding neovascularization, inflammation, and fibrogenesis is not well known. Here, we evaluated inflammatory angiogenesis and fibrogenesis induced by implantation of polyether-polyurethane sponges in mice targeted disrupted of the interferon-gamma gene (IFN-gamma-/- ) and wild-type (WT). The hemoglobin content, the number of vessels, and blood flow (evaluated by LDPI-laser Doppler perfusion imaging) were decreased in the implants from IFN-gamma-/- as compared to WT mice. Likewise, neutrophils and macrophages accumulation (MPO and NAG activities, respectively) was decreased in IFN-gamma-/- implants. Interestingly, while the local content of VEGF, TNF-alpha, CXCL-1/KC, as measured by ELISA, and iNOS expression, as measured by qPCR, were significantly reduced, the content of IL-10 was greatly increased in the implants from IFN-gamma-/- mice as compared to WT mice. No alterations were observed in CCL-2/MCP-1 levels. Lastly, the collagen deposition, assessed by Picro-Sirius red-stained histological sections, was also reduced in IFN-gamma-/- implants. Altogether, these data suggest that IFN-gamma activity contributes to inflammatory angiogenesis and fibrogenesis in synthetic implants and that lack of IFN-gamma expression attenuates foreign body reaction to implants in mice.

AB - PURPOSE: To present and evaluate a straightforward implementation of a marker less, respiratory motion-tracking process utilizing Kinect v2 camera as a gating tool during 4DCT or during radiotherapy treatments. METHODS: Utilizing the depth sensor on the Kinect as well as author written C# code, respiratory motion of a subject was tracked by recording depth values obtained at user selected points on the subject, with each point representing one pixel on the depth image. As a patient breathes, specific anatomical points on the chest/abdomen will move slightly within the depth image across pixels. By tracking how depth values change for a specific pixel, instead of how the anatomical point moves throughout the image, a respiratory trace can be obtained based on changing depth values of the selected pixel. Tracking these values was implemented via marker-less setup. Varian's RPM system and the Anzai belt system were used in tandem with the Kinect to compare respiratory traces obtained by each using two different subjects. RESULTS: Analysis of the depth information from the Kinect for purposes of phase- and amplitude-based binning correlated well with the RPM and Anzai systems. Interquartile Range (IQR) values were obtained comparing times correlated with specific amplitude and phase percentages against each product. The IQR time spans indicated the Kinect would measure specific percentage values within 0.077 s for Subject 1 and 0.164 s for Subject 2 when compared to values obtained with RPM or Anzai. For 4DCT scans, these times correlate to less than 1 mm of couch movement and would create an offset of 1/2 an acquired slice. CONCLUSION: By tracking depth values of user selected pixels within the depth image, rather than tracking specific anatomical locations, respiratory motion can be tracked and visualized utilizing the Kinect with results comparable to that of the Varian RPM and Anzai belt.

AB - Spinal cord injury (SCI) normally results in cell death, scarring, cavitation, inhibitory molecules release, etc., which are regarded as a huge obstacle to reconnect the injured neuronal circuits because of the lack of effective stimulus. In this study, a functional gelatin sponge scaffold was used to inhibit local inflammation, enhance nerve fiber regeneration, and improve neural conduction in the canine. This scaffold had good porosity and modified with neurotrophin-3 (NT-3)/fibroin complex, which showed sustained release in vitro. After the scaffold was transplanted into canine spinal cord hemisection model, hindlimb movement, and neural conduction were improved evidently. Migrating host cells, newly formed neurons with associated synaptic structures together with functional blood vessels with intact endothelium in the regenerating tissue were identified. Taken together, the results demonstrated that using bioactive scaffold could establish effective microenvironment stimuli for endogenous regeneration, providing a potential and practical strategy for treatment of spinal cord injury.

PMID- 29577605 TI - Increased factor VIII plays a significant role in plasma hypercoagulability phenotype of patients with cirrhosis. AB - : Essentials The role of increased factor VIII in cirrhosis-induced hypercoagulability has never been demonstrated. Factor VIII and protein C effects were characterized by thrombin generation with thrombomodulin. Factor VIII elevation plays a significant role in cirrhosis-induced plasma hypercoagulability. Only protein C and factor VIII normalization led to thrombin generation similar to controls. SUMMARY: Background In cirrhosis, thrombin generation (TG) studied in the presence of thrombomodulin (TM) indicates plasma hypercoagulability. Although the role of protein C (PC) deficiency has been investigated, the influence of an increase in the factor VIII level has never been addressed. Objectives We investigated the roles of high FVIII and low PC levels in increased TG in the presence of TM. Methods Blood samples were prospectively collected from 35 healthy controls and 93 patients with cirrhosis (Child-Turcotte-Pugh [CTP]-A, n = 61; CTP-B, n = 19; and CTP-C, n = 13) and FVIII levels > 150% (n = 48) and/or PC levels < 70% (n = 88). TG was performed with tissue factor (5 pm), phospholipids, and TM (4 nm). FVIII and PC levels were normalized by adding an inhibitory anti-FVIII antibody and exogenous PC, respectively. Results The endogenous thrombin potential (ETP) in the presence of TM was higher in patients than in controls. After FVIII normalization, the ETP (median) decreased from 929 nm min to 621 nm min (CTP-A), 1122 nm min to 1082 nm min (CTP-B), and 1221 nm min to 1143 nm min (CTP-C); after PC normalization, it decreased from 776 nm min to 566 nm min (CTP-A), 1120 nm min to 790 nm min (CTP B), and 995 nm min to 790 nm min (CTP-C). The ETP was reduced by 17% and 30%, respectively, but normal TG was not restored. When both FVIII and PC levels were normalized, the ETP decreased from 929 nm min to 340 nm min (CTP-A), 1122 nm min to 506 nm min (CTP-B), and 1226 nm min to 586 nm min (CTP-C), becoming similar to control levels. Conclusion Cirrhosis-induced plasma hypercoagulability, as demonstrated in these experimental conditions, can be partly explained by opposite changes in two factors: PC level (decrease) and FVIII level (increase).

AB - Breast cancer (BC) is the most common cancer in women that requires special attention due to low response to conventional treatments. The common method for treating cancer (especially BC) is applying a single anticancer agent, however, due to some disadvantages including cytotoxicity, side effects, and multidrug resistance, the efficiency and application of this method are limited. To overcome these challenges, the combinational delivery of anticancer drugs (including chemical agents, genetic materials, etc.) has been introduced. To increase the efficacy of this new method, several nanocarriers including inorganic nanoparticles (such as, magnetic nanoparticles, silica nanoparticles, etc.) and organic ones (e.g., dendrimers, liposomes, micelles, and polymeric nanoparticles) have been used. Based on the literature, combinational delivery using nanocarriers showed promising results in the treatment of BC. In this review, combination regimens for the treatment of BC, nanocarriers containing combinations of pharmaceutical agents (including small molecule chemotherapeutic, biological, and gene therapy agents) as an opportunity to overcome chemotherapy challenges and, finally, examples of these formulations have been presented. This review aims to provide a better understanding of these increasingly important new methods of cancer treatment and the main issues and key considerations for a rational design of nanocarriers used in combinational delivery of different synergistic anticancer agents.

AB - Cartilage tissue engineering strategies that use in situ forming degradable hydrogels for mesenchymal stem cell (MSC) delivery are promising for treating chondral defects. Hydrogels that recapitulate aspects of the native tissue have the potential to encourage chondrogenesis, permit cellular mediated degradation, and facilitate tissue growth. This study investigated photoclickable poly(ethylene glycol) hydrogels, which were tailored to mimic the cartilage microenvironment by incorporating extracellular matrix analogs, chondroitin sulfate and RGD, and crosslinks sensitive to matrix metalloproteinase 7 (MMP7). Human MSCs were encapsulated in the hydrogel, cultured up to nine weeks, and assessed by mRNA expression, protein production and biochemical analysis. Chondrogenic genes, SOX9, ACAN, and COL2A1, significantly increased with culture time, and the ratios of COL2A1:COL10A1 and SOX9:RUNX2 reached values of ~20-100 by week 6. The encapsulated MSCs degraded the hydrogel, which was nearly undetectable by week 9. There was substantial deposition of aggrecan and collagen II, which correlated with degradation of the hydrogel. Minimal collagen X was detectable, but collagen I was prevalent. After week 1, extracellular matrix elaboration was accompanied by a ~twofold increase in compressive modulus with culture time. The MMP7-sensitive cartilage mimetic hydrogel supported MSC chondrogenesis and promoted macroscopic neocartilaginous matrix elaboration representative of fibrocartilage.

PMID- 29577608 TI - Impact of salvage treatment modalities in patients with positive FDG-PET/CT after R-CHOP chemotherapy for aggressive B-cell non-Hodgkin lymphoma. AB - INTRODUCTION: To compare outcomes of different salvage treatment modalities in patients with aggressive B-cell non-Hodgkin lymphoma (NHL) who remain FDG-PET positive after R-CHOP chemotherapy. Existing data on these patients with FDG-PET primary refractory disease are limited. METHODS: Patients with diffuse large B cell lymphoma or grade 3 follicular lymphoma were retrospectively reviewed from the Prince of Wales Hospital databases. Eligibility criteria were: age>=18 years, treated with R-CHOP, with positive post-chemotherapy FDG-PET. Salvage treatment modalities were: radical radiotherapy (RT, dose>=30 Gy), high dose chemotherapy and autologous stem cell transplant (ASCT), or non-radical management. Survival was calculated from date of post-chemotherapy FDG-PET to last follow-up. RESULTS: Twenty-six patients from 2003-2015 met the inclusion criteria. Median age was 60 (range 19-84). Most had adverse baseline features: 21 (81%) stage III-IV, 24 (92%) bulky disease and nine (35%) skeletal involvement. Characteristics of PET positivity post-chemotherapy were single site in 16 (62%), sites of prior bulk in 24 of 24, skeletal sites in five of nine, and able to be encompassed by RT in 21 (81%). Salvage treatment was: radical RT in 17 (65%), ASCT in four (15%) and non radical in five (20%). Median follow-up of surviving patients was 31 months. Kaplan-Meier estimates of 3-year PFS and OS were 41% and 52%, respectively. By salvage modality, 3-year PFS was 51% for RT, 25% for ASCT and 20% for non-radical treatment, (P = 0.453); 3-year OS was respectively 65%, 25% and 40% (P = 0.173). CONCLUSION: Patients with FDG-PET positive disease after R-CHOP for aggressive B cell NHL are salvageable with radiotherapy. PMID- 29577609 TI - The potential of the stem cells composite hydrogel wound dressings for promoting wound healing and skin regeneration: In vitro and in vivo evaluation. AB - In this study, the wound healing properties of the gelatin-based hydrogel (GBH) wound dressing combined with adipose-derived stem cells (ADSCs) were investigated using the mouse and porcine models. The analytical results showed that the ADSCs harvested from the porcine significantly increased cell growth and promoted cell differentiation (adipogenesis and osteogenesis) in comparison to the ADSCs harvested from the mouse in vitro. Moreover, the in vivo results also indicated that the GBH wound dressing combined with ADSCs and its culture medium could potentially accelerate wound healing in the mouse and porcine models. The ADSCs presented a possibility of recovery from wounds and injuries through skin regeneration. Therefore, both in vitro and in vivo results demonstrated that the ADSCs can potentially be an effective clinical treatment through the GBH wound dressing, which is a promising evidence-based complementary and alternative medicine for skin regeneration.

PMID- 29577610 TI - Is postponed laparoscopic cholecystectomy justified for acute cholecystitis appearing early after onset? AB - INTRODUCTION: Early laparoscopic cholecystectomy (ELC) is considered the standard treatment for acute cholecystitis for patients who can tolerate surgery. The ideal time for performing ELC is reported to be 72 h from onset. However, many patients undergo surgery on or after the fourth day from onset, even if they presented early after onset. A few reports have investigated the feasibility and disadvantages of this so-called "postponed laparoscopic cholecystectomy" (PLC). METHODS: This study consisted of 215 patients who had undergone laparoscopic cholecystectomy for acute cholecystitis within 6 days of onset between July 2006 and December 2017. Patients were divided into an ELC group (patients who underwent LC within 3 days of symptom onset, n = 172) and a PLC group (patients who underwent LC 4-6 days from symptom onset and on or after 3 days from admission, n = 43). Comparisons were made between these groups. RESULTS: Perioperative outcomes between the PLC and ELC groups were not significantly different, except for the requirement of subtotal cholecystectomy (SC) (16.2% vs 5.2%, P = 0.013). In the PLC group, persistent fever after admission was significantly associated with the need for SC (P = 0.036). CONCLUSIONS: PLC for acute cholecystitis performed within 6 days of onset gave acceptable perioperative outcomes, except for an increased requirement for SC. Surgeons should keep in mind that PLC may increase the need for SC. A persistent fever after admission may be a risk factor for SC in the PLC group. PMID- 29577611 TI - SRARP and HSPB7 are epigenetically regulated gene pairs that function as tumor suppressors and predict clinical outcome in malignancies. AB - Deletions of chromosome 1p36 are common in cancers; however, despite extensive studies, there has been limited success for discovering candidate tumor suppressors in this region. SRARP has recently been identified as a novel corepressor of the androgen receptor (AR) and is located on chromosome 1p36. Here, bioinformatics analysis of large tumor datasets was performed to study SRARP and its gene pair, HSPB7. In addition, using cancer cell lines, mechanisms of SRARP and HSPB7 regulation and their molecular functions were investigated. This study demonstrated that SRARP and HSPB7 are a gene pair located 5.2 kb apart on 1p36.13 and are inactivated by deletions and epigenetic silencing in malignancies. Importantly, SRARP and HSPB7 have tumor suppressor functions in clonogenicity and cell viability associated with the downregulation of Akt and ERK. SRARP expression is inversely correlated with genes that promote cell proliferation and signal transduction, which supports its functions as a tumor suppressor. In addition, AR exerts dual regulatory effects on SRARP, and although an increased AR activity suppresses SRARP transcription, a minimum level of AR activity is required to maintain baseline SRARP expression in AR+ cancer cells. Furthermore, as observed with SRARP, HSPB7 interacts with the 14-3-3 protein, presenting a shared molecular feature between SRARP and HSPB7. Of note, genome- and epigenome-wide associations of SRARP and HSPB7 with survival strongly support their tumor suppressor functions. In particular, DNA hypermethylation, lower expression, somatic mutations, and lower copy numbers of SRARP are associated with worse cancer outcome. Moreover, DNA hypermethylation and lower expression of SRARP in normal adjacent tissues predict poor survival, suggesting that SRARP inactivation is an early event in carcinogenesis. In summary, SRARP and HSPB7 are tumor suppressors that are commonly inactivated in malignancies. SRARP inactivation is an early event in carcinogenesis that is strongly associated with worse survival, presenting potential translational applications. PMID- 29577612 TI - Physical validation of UF-RIPSA: A rapid in-clinic peak skin dose mapping algorithm for fluoroscopically guided interventions. AB - PURPOSE: The purpose of this study was to experimentally validate UF-RIPSA, a rapid in-clinic peak skin dose mapping algorithm developed at the University of Florida using optically stimulated luminescent dosimeters (OSLDs) and tissue equivalent phantoms. METHODS: The OSLDs used in this study were InLightTM Nanodot dosimeters by Landauer, Inc. The OSLDs were exposed to nine different beam qualities while either free-in-air or on the surface of a tissue equivalent phantom. The irradiation of the OSLDs was then modeled using Monte Carlo techniques to derive correction factors between free-in-air exposures and more complex irradiation geometries. A grid of OSLDs on the surface of a tissue equivalent phantom was irradiated with two fluoroscopic x ray fields generated by the Siemens Artis zee bi-plane fluoroscopic unit. The location of each OSLD within the grid was noted and its dose reading compared with UF-RIPSA results. RESULTS: With the use of Monte Carlo correction factors, the OSLD's response under complex irradiation geometries can be predicted from its free-in-air response. The predicted values had a percent error of -8.7% to +3.2% with a predicted value that was on average 5% below the measured value. Agreement within 9% was observed between the values of the OSLDs and RIPSA when irradiated directly on the phantom and within 14% when the beam first traverses the tabletop and pad. CONCLUSIONS: The UF-RIPSA only computes dose values to areas of irradiated skin determined to be directly within the x ray field since the algorithm is based upon ray tracing of the reported reference air kerma value, with subsequent corrections for air-to-tissue dose conversion, x ray backscatter, and table/pad attenuation. The UF-RIPSA algorithm thus does not include the dose contribution of scatter radiation from adjacent fields. Despite this limitation, UF-RIPSA is shown to be fairly robust when computing skin dose to patients undergoing fluoroscopically guided interventions. PMID- 29577613 TI - Molecular biological analysis in a patient with multiple lung adenocarcinomas. AB - The utility of molecular biological analysis in lung adenocarcinoma has been demonstrated. Herein we report a rare case presenting as multiple lung adenocarcinomas with four different EGFR gene mutations detected in three lung tumors. After opacification was detected by routine chest X-ray, the patient, a 64-year-old woman, underwent chest computed tomography which revealed a right lung segment S4 ground-glass nodule (GGN). Follow-up computed tomography revealed a 42 mm GGN nodule with a 26 mm nodule (S6) and a 20 mm GGN (S10). Histopathology of resected specimens from the right middle and lower lobes revealed all three nodules were adenocarcinomas. Four EGFR mutations were detected; no three tumors had the same mutations. Molecular biological analysis is a promising tool for the diagnosis of primary tumors in patients with multiple lung carcinomas of the same histotype, enabling appropriate treatment. PMID- 29577614 TI - Fully automated searching for the optimal VMAT jaw settings based on Eclipse Scripting Application Programming Interface (ESAPI) and RapidPlan knowledge-based planning. AB - PURPOSE: Eclipse treatment planning system has not been able to optimize the jaw positions for Volumetric Modulated Arc Therapy (VMAT). The arbitrary and planner dependent jaw placements define the maximum field size within which multi-leaf collimator (MLC) sequences can be optimized to modulate the beam. Considering the mechanical constraints of MLC transitional speed and range, suboptimal X jaw settings may impede the optimization or undermine the deliverability. This work searches optimal VMAT jaw settings automatically based on Eclipse Scripting Application Programming Interface (ESAPI) and RapidPlan knowledge-based planning. METHODS AND MATERIALS: Using an ESAPI script, the X jaws of rectal VMAT plans were initially set to conform the planning-target-volume (PTV), and were gradually extended toward the isocenter (PTV center) in 5-7 mm increments. Using these jaw pairs, 592 plans were automatically created for 10 patients and quantitatively evaluated using a comprehensive scoring function. A published RapidPlan model was evoked by ESAPI to generate patient-specific optimization objectives without manual intervention. All candidate plans were first stored as text files to save storage space, and only the best, worst, and conformal plans were consequently recreated for comparison. RESULTS: Although RapidPlan estimates dose-volume histogram (DVH) based on individual anatomy, the geometry-based expected dose (GED) algorithm does not recognize different jaw settings but uses PTV-conformal jaws as default; hence, identical DVHs were observed regardless of planner-defined jaws. Therefore, ESAPI finalized dose-volume calculation and eliminated the plans with unacceptable hotspots before comparison. The plan quality varied dramatically with different jaw settings. Trade-offs among different organs-at-risk (OARs) were collectively considered by the proposed scoring method, which identified the best and worst plans correctly. The plans using conformal jaws were neither the best nor the worst of all candidates. CONCLUSIONS: VMAT plans using optimal jaw locations can be created automatically using ESAPI and RapidPlan. Conformal jaws are not the optimal choice. PMID- 29577615 TI - Comparative pharmacokinetic study of the components of Jia-Wei-Kai-Xin-San in normal and vascular dementia rats by ultra-fast liquid chromatography coupled with tandem mass spectrometry. AB - A fast, sensitive, and reliable ultra-high performance liquid chromatography coupled with tandem mass spectrometry method has been developed and validated for simultaneous quantification of geniposide, polygalaxanthone III, 3,6'-disinapoyl sucrose, alpha-asarone, beta-asarone, poricoic acid A, poricoic acid B, dehydrotumulosic acid, deoxyschizandrin, schizandrin B, and kaempferide in plasma after oral administration of extracts of Jia-Wei-Kai-Xin-San in normal and vascular dementia rats. The developed method was precise and accurate within the linearity range of the analytes. The lower limits of quantification were 1.04 2.68 ng/mL for all the analytes. Both intra- and inter day precision and accuracy of the analytes were all within accepted criteria. The mean extraction recoveries of the analytes and the internal standard from rat plasma were all >60.0%. The validated method had been successfully applied to compare pharmacokinetic profiles of the analytes in plasma of normal and vascular dementia rat treated with herbal extracts. Results indicated that differences existed between normal and vascular dementia model rats except dehydrotumulosic acid and kaempferide, which might be due to the pathology of vascular dementia and pharmacological effect of the analytes. These pharmacokinetic studies might benefit for the mechanism exploration and clinical use of traditional Chinese medicine formulae. PMID- 29577616 TI - Skating on thin ice: stimulant use and sub-optimal adherence to HIV pre-exposure prophylaxis. AB - INTRODUCTION: Stimulant and heavy alcohol use are prevalent and associated with elevated risk for HIV seroconversion among men who have sex with men (MSM) and transgender women. In addition, each can pose difficulties for antiretroviral adherence among people living with HIV. Scant research has examined the associations of stimulant and heavy alcohol use with adherence to daily oral pre exposure prophylaxis (PrEP) among MSM and transgender women. To address this gap in the literature, we evaluated the hypothesis that stimulant use and binge drinking are prospectively associated with sub-optimal PrEP adherence. METHODS: We analysed data from participants in a nested case-cohort in the iPrEx open label extension. Stimulant use (i.e. powder cocaine, crack-cocaine, cocaine paste, methamphetamine, cathinone) and binge drinking (i.e. >=5 drinks in a single day) in the last 30 days were assessed. Baseline urine was tested for stimulants using immunoassays to reduce misclassification. Sub-optimal adherence was defined as tenofovir drug concentrations in dried blood spots less than 700 fmol per punch, indicative of less than four doses per week. We tested the prospective association of stimulant use and binge drinking with sub-optimal adherence at the 4-week follow-up visit. RESULTS AND DISCUSSION: Data from 330 participants were analysed. The majority of the participants were MSM (89%) with a median age at baseline of 29 years (interquartile range 24 to 39). Approximately 16% (52/330) used stimulants and 22% (72/330) reported binge drinking in the last 30 days. Stimulant users had fivefold greater odds of sub optimal PrEP adherence compared to non-users in adjusted analysis (adjusted odds ratio [aOR] 5.04; [95% CI 1.35 to 18.78]). Self-reported binge drinking was not significantly associated with sub-optimal adherence after adjusting for stimulant use and baseline confounders (aOR 1.16 [0.49 to 2.73]). Depressive symptoms, being transgender, and number of sex partners were also not significantly associated with sub-optimal PrEP adherence (p > 0.05). CONCLUSIONS: Stimulant use is a risk factor for sub-optimal PrEP adherence in the month following PrEP initiation. Comprehensive prevention approaches that reduce stimulant use may optimize PrEP adherence. Creating adherence plans that specifically address PrEP dosing in the context of ongoing stimulant use should also be considered. PMID- 29577617 TI - A time-motion study of cardiovascular disease risk factor screening integrated into HIV clinic visits in Swaziland. AB - INTRODUCTION: Screening of modifiable cardiovascular disease (CVD) risk factors is recommended but not routinely provided for HIV-infected patients, especially in low-resource settings. Potential concerns include limited staff time and low patient acceptability, but little empirical data exists. As part of a pilot study of screening in a large urban HIV clinic in Swaziland, we conducted a time-motion study to assess the impact of screening on patient flow and HIV service delivery and exit interviews to assess patient acceptability. METHODS: A convenience sample of patients >=40 years of age attending routine HIV clinic visits was screened for hypertension, diabetes, hyperlipidemia and tobacco smoking. We observed HIV visits with and without screening and measured time spent on HIV and CVD risk factor screening activities. We compared screened and unscreened patients on total visit time and time spent receiving HIV services using Wilcoxon rank-sum tests. A separate convenience sample of screened patients participated in exit interviews to assess their satisfaction with screening. RESULTS: We observed 172 patient visits (122 with CVD risk factor screening and 50 without). Screening increased total visit time from a median (range) of 4 minutes (2 to 11) to 15 minutes (9 to 30) (p < 0.01). Time spent on HIV care was not affected: 4 (2 to 10) versus 4 (2 to 11) (p = 0.57). We recruited 126 patients for exit interviews, all of whom indicated that they would recommend screening to others. CONCLUSION: Provision of CVD risk factor screening more than tripled the length of routine HIV clinic visits but did not reduce the time spent on HIV services. Programme managers need to take longer visit duration into account in order to effectively integrate CVD risk factor screening and counselling into HIV programmes. PMID- 29577618 TI - Flavan-3-ol/Procyanidin Metabolomics in Rat Urine Using HPLC-Quadrupole TOF/MS. AB - SCOPE: Several studies have demonstrated that flavan-3-ol/procyanidins are associated with biological functions in the prevention of various chronic diseases, including obesity and diabetes. Knowledge of their mechanisms, including bioavailability, has significantly progressed in the last decade. However, the differences of the metabolic signatures among flavan-3 ol/procyanidins remain ambiguous. METHODS AND RESULTS: The metabolites in urine over time after acute administration of three typical flavan-3-ol/procyanidins ((epi)catechin [EPC], epigallocatechin gallate [EGCG], and procyanidin dimer [PC]) in view of the chemical structure were analyzed by HPLC-quadrupole TOF/MS. Several bile acid and amino acid derivatives including tryptophan and tyrosine, as well as flavan-3-ol/procyanidin conjugates and phenolic acid degradation products generated by the gut microbiota were observed in rat urine. CONCLUSION: Multivariate statistical analyses suggest that the exogenous and endogenous metabolites of flavan-3-ol/procyanidins greatly differ, although the chemical structures of three typical flavan-3-ol/procyanidins-EPC, EGCG, and PC-are similar. Thus, metabolomic differences likely affect their biological functions and health benefits. PMID- 29577620 TI - Erratum. PMID- 29577619 TI - Cellular and molecular mechanisms of vitamin D in food allergy. AB - Food allergies are becoming increasingly prevalent, especially in young children. Epidemiological evidence from the past decade suggests a role of vitamin D in food allergy pathogenesis. Links have been made between variations in sunlight exposure, latitude, birth season and vitamin D status with food allergy risk. Despite the heightened interest in vitamin D in food allergies, it remains unclear by which exact mechanism(s) it acts. An understanding of the roles vitamin D plays within the immune system at the cellular and genetic levels, as well as the interplay between the microbiome and vitamin D, will provide insight into the importance of the vitamin in food allergies. Here, we discuss the effect of vitamin D on immune cell maturation, differentiation and function; microbiome; genetic and epigenetic regulation (eg DNA methylation); and how these processes are implicated in food allergies.

AB - Exploiting high-performance, robust, and cost-effective electrocatalysts for the oxygen evolution reaction (OER) is crucial for electrochemical energy storage and conversion technologies. Engineering the interfacial structure of hybrid catalysts often induces synergistically enhanced electrocatalytic performance. Herein, a new strongly coupled heterogeneous catalyst with proper interfacial structures, i.e., CoO nanoclusters decorated on CoFe layered double hydroxides (LDHs) nanosheets, is prepared via a simple one-step pulsed laser ablation in liquid method. Thorough spectroscopic characterizations reveal that strong chemical couplings at the hybrid interface trigger charge transfer from CoII in the oxide to FeIII in the LDHs through the interfacial Fe?O?Co bond, leading to considerable amounts of high oxidation state CoIII sites present in the hybrid. Interestingly, the CoO/CoFe LDHs exhibit pronounced synergistic effects in electrocatalytic water oxidation, with substantially enhanced intrinsic catalytic activity and stability relative to both components. The hybrid catalyst achieves remarkably low OER overpotential and Tafel slope in alkaline medium, outperforming that of Ru/C and manifesting itself among the most active Co-based OER catalysts. PMID- 29577622 TI - Controllable Construction of Core-Shell Polymer@Zeolitic Imidazolate Frameworks Fiber Derived Heteroatom-Doped Carbon Nanofiber Network for Efficient Oxygen Electrocatalysis. AB - Designing rational nanostructures of metal-organic frameworks based carbon materials to promote the bifunctional catalytic activity of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is highly desired but still remains a great challenge. Herein, an in situ growth method to achieve 1D structure-controllable zeolitic imidazolate frameworks (ZIFs)/polyacrylonitrile (PAN) core/shell fiber (PAN@ZIFs) is developed. Subsequent pyrolysis of this precursor can obtain a heteroatom-doped carbon nanofiber network as an efficient bifunctional oxygen electrocatalyst. The electrocatalytic performance of derived carbon nanofiber is dominated by the structures of PAN@ZIFs fiber, which is facilely regulated by efficiently controlling the nucleation and growth process of ZIFs on the surface of polymer fiber as well as optimizing the components of ZIFs. Benefiting from the core-shell structures with appropriate dopants and porosity, as-prepared catalysts show brilliant bifunctional ORR/OER catalytic activity and durability. Finally, the rechargeable Zn-air battery assembled from the optimized catalyst (CNF@Zn/CoNC) displays a peak power density of 140.1 mW cm 2 , energy density of 878.9 Wh kgZn-1 , and excellent cyclic stability over 150 h, giving a promising performance in realistic application. PMID- 29577623 TI - HIV incidence among people who inject drugs in the Middle East and North Africa: mathematical modelling analysis. AB - INTRODUCTION: Emerging HIV epidemics have been documented among people who inject drugs (PWID) in the Middle East and North Africa (MENA). This study estimates the HIV incidence among PWID due to sharing needles/syringes in MENA. It also delineates injecting drug use role as a driver of the epidemic in the population, and estimates impact of interventions. METHODS: A mathematical model of HIV transmission among PWID was applied in seven MENA countries with sufficient and recent epidemiological data and HIV prevalence >=1% among PWID. Estimations of incident and/or prevalent infections among PWID, ex-PWID and sexual partners of infected current and ex-PWID were conducted. RESULTS: The estimated HIV incidence rate for 2017 among PWID ranged between 0.7% per person-year (ppy) in Tunisia and 7.8% ppy in Pakistan, with Libya being an outlier (24.8% ppy). The estimated number of annual new infections was lowest in Tunisia (n = 79) and Morocco (n = 99), and highest in Iran and Pakistan (approximately n = 6700 each). In addition, 20 to 2208 and 5 to 837 new annual infections were estimated across the different countries among sexual partners of PWID and ex-PWID respectively. Since epidemic emergence, the number of total ever acquired incident infections across countries was 706 to 90,015 among PWID, 99 to 18,244 among sexual partners of PWID, and 16 to 4360 among sexual partners of ex-PWID. The estimated number of prevalent infections across countries was 341 to 23,279 among PWID, 119 to 16,540 among ex PWID, 67 to 10,752 among sexual partners of PWID, and 12 to 2863 among sexual partners of ex-PWID. Increasing antiretroviral therapy (ART) coverage to the global target of 81% - factoring in ART adherence and current coverage - would avert about half of new infections among PWID and their sexual partners. Combining ART with harm reduction could avert over 90% and 70% of new infections among PWID and their sexual partners respectively. CONCLUSIONS: There is considerable HIV incidence among PWID in MENA. Of all new infections ultimately due to injecting drug use, about 75% are among PWID and the rest among sexual partners. Of all prevalent infections ultimately attributed to injecting drug use as epidemic driver, about half are among PWID, 30% among ex-PWID and 20% among sexual partners of PWID and ex-PWID. These findings call for scale-up of services for PWID, including harm reduction as well as testing and treatment services. PMID- 29577624 TI - Attitudes toward early palliative care in cancer patients and caregivers: a Korean nationwide survey. AB - Integrated early palliative care (EPC) improves quality of life and reduces psychological distress in adult patients with cancer and caregivers, but attitudes toward EPC have been poorly studied. We aimed to investigate attitudes toward EPC in a nationwide survey of patients with cancer and caregivers. From July to October 2016, we administered nationwide questionnaires examining attitudes toward EPC in patients with cancer (n = 1001) and their families (n = 1006) from 12 Korean hospitals. When an individual considered EPC unnecessary, the reasons were collected and analyzed. Factors associated with perception of EPC were examined. A majority of patients (84.5%) and caregivers (89.5%) had positive attitudes toward EPC. The most common reasons for deeming EPC unnecessary were that EPC may be an obstacle to cancer treatment (patients: 37%; caregivers: 23%; respectively) or that they were not sure if EPC is beneficial (patients: 21%; caregivers: 24%; respectively). Financial burden as a reason was more evident in caregivers (23%) than in patients (17%). Male gender, age <50, early stage, intensive care unit admission, and not believing that dying people should prepare to practice charity were associated with patients' negative attitudes. In caregivers, opposition to EPC was associated with not thinking death should be feared, not thinking people should be remembered, and lower educational level. Our findings showed that significant numbers of patients with advanced cancer and family caregivers showed positive attitudes toward EPC. However, more than 10% of participants did not consider EPC necessary. Physicians' communication with patients and caregivers and financial support could help overcome the barriers of EPC.

AB - Photoacoustic ophthalmoscopy (PAOM) is capable of noninvasively imaging anatomic and functional information of the retina in living rodents. However, the strong ocular aberration in rodent eyes and limited ultrasonic detection sensitivity affect PAOM's spatial resolution and signal-to-noise ratio (SNR) in in vivo eyes. In this work, we report a computational approach to combine blind deconvolution (BD) algorithm with a regularizing constraint based on total variation (BDTV) for PAOM imaging restoration. We tested the algorithm in retinal and choroidal microvascular images in albino rat eyes. The algorithm improved PAOM's lateral resolution by around 2-fold. Moreover, it enabled the improvement in imaging SNR for both major vessels and capillaries, and realized the well-preserved blood vessels' edges simultaneously, which surpasses conventional Richardson-Lucy BD algorithm. The reported results indicate that the BDTV algorithm potentially facilitate PAOM in extracting retinal pathophysiological information by enhancing in vivo imaging quality without physically modifying PAOM's optical configuration. PMID- 29577626 TI - Alcohol-Soluble Electron-Transport Materials for Fully Solution-Processed Green PhOLEDs. AB - Two alcohol-soluble electron-transport materials (ETMs), diphenyl(4-(1-phenyl-1H benzo[d]imidazol-2-yl)phenyl)phosphine oxide (pPBIPO) and (3,5-bis(1-phenyl-1H benzo[d]imidazol-2-yl)phenyl)diphenylphosphine oxide (mBPBIPO), have been synthesized. The physical properties of these ETMs were investigated and they both exhibited high electron-transport mobilities (1.67*10-4 and 2.15*10-4 cm2 V-1 s-1 ), high glass-transition temperatures (81 and 110 degrees C), and low LUMO energy levels (-2.87 and -2.82 eV, respectively). The solubility of PBIPO in n-butyl alcohol was more than 20 mg mL-1 , which meets the requirement for fully solution-processed organic light-emitting diodes (OLEDs). Fully solution processed green-phosphorescent OLEDs were fabricated by using alcohol-soluble PBIPO as electron-transport layers (ETLs), and they exhibited high current efficiencies, power efficiencies, and external quantum efficiencies of up to 38.43 cd A-1 , 26.64 lm W-1 , and 10.87 %, respectively. Compared with devices that did not contain PBIPO as an ETM, the performance of these devices was much improved, which indicated the excellent electron-transport properties of PBIPO. PMID- 29577627 TI - Review article: Investigations and the pregnant woman in the emergency department - part 2: Point-of-care ultrasound, electrocardiography, respiratory function tests and radiology. AB - Accurate assessment of the pregnant patient in the ED depends on knowledge of physiological changes in pregnancy, and how these changes may impact on pathology tests, appearance on point-of-care ultrasound, electrocardiography and respiratory function tests. In addition, the emergency physician needs to be cognisant of disorders that are unique to or more common during pregnancy. Part 2 of this review addresses the role of point-of-care ultrasound in pregnancy, physiological changes that may affect interpretation of point-of-care ultrasound, changes in electrocardiography and respiratory function tests, and the safety of radiological procedures in the pregnant patient. Part 1 addressed potential deviations in laboratory investigation reference intervals resulting from physiological alterations in pregnancy and the important causes of abnormal laboratory results in pregnancy. PMID- 29577628 TI - Self-reported skin concerns: An epidemiological study of community-dwelling older people. AB - AIM: To identify the frequency and impact of self-reported skin concerns in community-dwelling older people. BACKGROUND: Globally, the population is getting older and it is essential to develop effective interventions to promote healthy ageing. Skin change with age is inevitable and renders this often neglected organ more vulnerable to damage and breakdown; this can be costly to individuals and society. Maintenance of skin health in older people presents a health challenge that has yet to be fully understood or addressed. METHODS: Cross-sectional, self reported questionnaire survey in England. Patients registered with participating general practices (n = 3), aged >=70 years, living in their own homes and able to give informed consent (n = 3,359) were sent a letter of invitation to a free health and care assessment, and 1116 responded. RESULTS: When asked "do you have any concerns about your skin?", 16.5% (n = 183) said yes. Of this group, the most common concerns were dry skin 80.7% (n = 146), itching 56.9% (n = 103) and aged appearance 61% (n = 113). Itch, dry skin and inflammation were rated as most bothersome. There was a significant association between the dry skin and itch chi2 (1) = 6.9, p < .05. CONCLUSION: Many community-dwelling older people suffer from skin concerns predominantly dry skin and itching that is often bothersome. IMPLICATIONS FOR PRACTICE: Skin health assessment is often absent in routine consultations with community-dwelling older people. Dry, itchy skin is prevalent and can be simply managed with low-cost interventions. This has the potential to reduce suffering and maintain or improve skin barrier function. Nurses and other health professionals should therefore routinely assess and advise on skin health care for this population. PMID- 29577629 TI - Efficacy and safety of intravitreal anti-tumour necrosis factor drugs in adults with non-infectious uveitis - a systematic review. AB - Anti-tumour necrosis factor (TNF) drugs have been extensively used in non infectious uveitis (NIU), when corticosteroids or conventional immunosuppressive drugs cannot adequately control inflammation or intolerable side-effects occur. However, systemic anti-TNF therapies are also associated with a myriad of side effects. Therefore, intravitreal administration of anti-TNF biologics has been employed to minimize patient morbidity and systemic adverse effects, while maintaining therapeutic effectivity. We undertook a systematic review to determine evidence of efficacy and safety of intravitreal administration of anti TNF drugs in adults with NIU. We conducted this systematic review according to the PRISMA guidelines. The protocol was registered with PROSPERO (CRD42016041946). We searched CENTRAL, MEDLINE and EMBASE, from inception to April 2017, as well as clinical trial registries and grey literature. The qualitative analysis included all studies of adult patients with a diagnosis of NIU and who received intravitreal anti-TNF drugs with a 4-week minimum follow-up. A total of 4840 references were considered for title and abstract screening. Seven full texts were screened, and five studies were considered for analysis. All studies were open-label, single-centre, prospective, non-randomized, interventional case series with a follow-up between 4 and 26 weeks, employing either adalimumab in two studies and infliximab in three. Three studies showed a treatment effect of anti-TNF intravitreal injections, while one study revealed short-term improvement and one study revealed no efficacy of anti-TNF intravitreal therapy. None of the studies reported ocular adverse effects but only two studies included electrophysiological assessment in the safety analysis and no study assessed systemic human anti-drug antibodies. The available evidence is not sufficiently robust to conclude about the clinical effectivity of intravitreal anti-TNF in NIU and so no recommendation can be made. In conclusion, intravitreal injection of anti-TNF antibodies remains a possible treatment option to be explored through robust clinical investigation. PMID- 29577630 TI - Diagnostic accuracy of diffusion-weighted imaging- magnetic resonance imaging compared to positron emission tomography/computed tomography in evaluating and assessing pathological response to treatment in adult patients with lymphoma: A systematic review. AB - The use of Positron emission tomography/computerised tomography (PET/CT) is well established in the staging and assessment of treatment response of lymphoma. Recent studies have suggested that whole body diffusion-weighted imaging magnetic resonance imaging (WB-DW-MRI) may be an alternative to PET/CT in both staging and assessment of treatment response. A systematic review was performed to assess the ability of DW-MRI in the assessment of treatment response in lymphoma. Pubmed, Medline, Web of Science and Embase databases were queried for studies examining whole body DW-MRI compared to PET/CT in adult patients using a protocol of search terms. We carried out an extensive assessment of titles, abstracts and full texts of relevant paper as well as quality assessment with the Quality Assessment of Diagnostic Accuracy (QUADAS-2) tool. Eight studies were found to meet the criteria and were included in our review and analysis. Overall, the quality of studies was found to be moderate, with good inter-rater agreement (K = 0.74). Data analysis showed that lesion-based assessment in 5 studies with pooled results had a sensitivity and specificity of 94.7% and 99.3%. Assessment with Cohen's Kappa coefficient showed agreement to be excellent (K = 0.88). Three studies were included for qualitative analysis, two of which showed good equivalence between PET/CT and DW-MRI. WB-DWI-MRI can be considered a sensitive and specific method for assessing treatment response in Lymphoma without the use of ionising radiation or administration of F-18 Flurodeoxyglucose. Further studies are needed to evaluate the optimum b-values in assessing treatment response. PMID- 29577631 TI - The regulatory mechanism of mammalian TRPMLs revealed by cryo-EM. AB - Transient receptor potential mucolipin (TRPML) channels are the most recently identified subfamily of TRP channels and have seen a surge of new reports revealing both structural and functional insight. In 2017, several groups published multiple conformations of TRPML channels using cryo-EM. Similar to other TRP channels, the ML subfamily consists of six transmembrane helices (S1 S6), and a pore region including S5, S6, and two pore helices (PH1 and PH2). However, these reports also reveal distinct structural characteristics of the ML subfamily. Asp residues within the luminal pore may function to control calcium/pH regulation. A synthetic agonist, ML-SA1, can bind to the pore region of TRPMLs to force a direct dilation of the lower gate. Finally, biophysical and electrophysiological characterizations reveal another natural agonist binding site in the unique domain of TRPMLs, presumably regulating the conformation of the S4-S5 linker to open the channel. This work elucidates the molecular architecture and provides insights into how multiple ligands regulate TRPMLs. PMID- 29577632 TI - Interleukin-2 receptor antagonists: Protective factors against new-onset diabetes after renal transplantation. AB - BACKGROUND: The aim of the present study was to examine the association between interleukin-2 receptor antagonists (IL-2Ra) and new-onset diabetes after transplantation (NODAT) among renal transplant recipients (RTRs). METHODS: Between January 1993 and March 2014, 915 patients underwent renal transplantation at Zhongshan Hospital. In all, 557 RTRs were included in the present retrospective cohort study. The incidence of NODAT in this cohort was determined and multivariate Cox regression analysis was used to evaluate the risk factors for NODAT and to show the association between IL-2Ra use and NODAT development among RTRs. The cumulative incidence of NODAT was compared between groups treated with or without IL-2Ra. RESULTS: The mean +/-SD postoperative follow-up was 5.08 +/-3.17 years. The incidence of NODAT at the end of follow-up was 20.3%. After adjusting for potential confounders in the multivariate logistic regression (i.e. age, sex, body mass index, history of smoking, family history of diabetes, duration of dialysis, type of dialysis, donor type, recovery of graft function, acute rejection, hepatitis B or C or cytomegalovirus infection, fasting plasma glucose levels before and 1 week after transplantation, preoperative total cholesterol and triglyceride levels, daily dose of glucocorticoid, immunosuppressive regimen type, and immunosuppressant concentration after transplantation), IL-2Ra use was found to be related to a reduced incidence of NODAT. CONCLUSIONS: Use of IL-2Ra is associated with protection against the development of NODAT in RTRs. PMID- 29577633 TI - Impact of pediatric cancer on family relationships. AB - Little is known about the impact of cancer on family relationships from the perspective of the pediatric cancer patient and their sibling(s). This study assessed and compared children's experiences of family relationships in patients receiving active cancer therapy, those who have completed therapy, and siblings. A cross-sectional study of children with cancer and their siblings aged 8-17 years old was conducted. Children completed the PROMIS Pediatric Family Relationships short form and the Depressive Symptoms, Anxiety, and Peer Relationships short forms. The Mann-Whitney test assessed differences in Family Relationships scores between therapy groups, while the Wilcoxon signed-rank test assessed differences between patients and siblings. An actor-partner interdependence model (APIM) was used to assess how patient and sibling variables were associated with their own and each others' family relationships. Two hundred and sixty-five children completed the assessments. Siblings of patients on therapy had worse family relationships than patients on-therapy (P = 0.015). Family relationships of patients off-therapy did not differ from their siblings or the patients on-therapy. Family relationships scores did not differ between the sibling cohorts. The APIM found patient family relationships were impaired when their own peer relationships decreased and when either their own or their siblings had increased depressive symptoms. Sibling family relationships were impaired when their own depression increased, and when the patient counterpart was female, younger age, had less depressive symptoms, more anxiety or a diagnosis of leukemia/lymphoma (compared to solid tumor). Based on these findings, increased psychosocial resources for patients and siblings of children undergoing cancer therapy may be warranted. PMID- 29577634 TI - Molecular epidemiology of Shiga toxin-producing O113:H21 isolates from cattle and meat. AB - The serotype O113:H21 is considered one of the relevant non-O157 STEC serotypes associated with severe human infections. Due to the increased detection of O113 strains and their relationship with clinical cases, which emphasizes the importance of this serogroup as an emerging pathogen, our aim was to determine the characteristics of STEC O113:H21 strains circulating in bovine cattle and retail meat from Argentina. For this purpose, we determined the presence and combinations of various virulence genes (and their variants) related to adhesion and toxicity in a collection of 34 isolates. Their genetic relatedness using multiple-locus variable-number tandem repeat analysis (MLVA) was also studied. Subtyping of stx genes indicated that O113:H21 strains circulating in Argentina mainly present stx2a alone or together with stx2c or, less frequent, with stx2d , all of which are subtypes associated with human disease. We found plasmid markers, such as saa, ehxA and subA, in a higher proportion than previous studies, and five variants of saa, two of which were novel ones. In relation to MLVA subtyping, we detected a limited diversity among the isolates considering that several loci were not discriminative and, that in some farms, the same clone seemed to remain circulating throughout the year. The O113:H21 strains studied harbour several toxin and adhesion genes (saa, espP, fimCD, ehaA, iha, hcpA, elfA, lpfO113, ecpA, subA, cdt-V) and Stx subtypes associated with human disease. Results also highlighted that subtyping of stx and saa is useful to discriminate O113:H21 strains that share virulence genes. In conclusion, this study shows that a number of O113:H21 strains that occur in foods and bovines could be pathogenic for humans. This situation calls for further attention in the prevention and control of foodborne disease caused by these strains. PMID- 29577635 TI - Carbon Monoxide-Releasing Molecule Enhances Coagulation and Decreases Fibrinolysis in Normal Canine Plasma. AB - The dog is an important companion animal and also purpose-bred for research studies. Coagulopathies in dogs are common, although the availability of blood products for therapy is inconsistent throughout the profession. A pro-coagulant therapeutic that is readily available and easily stored would be useful for the treatment of coagulopathies. Tricarbonyldichlororuthenium (II) dimer [Carbon monoxide-releasing molecule-2 (CORM-2)] acts as a prothrombotic agent in plasma by increasing the velocity of clot formation and clot strength, and by decreasing the clot's vulnerability to fibrinolysis. We sought to test CORM-2's effect on coagulation and fibrinolysis in vitro in canine plasma using thromboelastography. Measures of the rate of clot formation and clot strength in plasma without CORM-2 were highly correlated with fibrinogen concentration. We found that CORM-2 significantly enhanced the rate of clot formation and clot strength and significantly reduced the rate of fibrinolysis and the clot lysis time. The per cent change in rate of clot formation and clot strength was not significantly correlated with fibrinogen concentration, indicating that CORM-2's pro-coagulant effect is not dependent on fibrinogen concentration. This study corroborates studies in other species that show that CORM-2 is pro-coagulant in plasma, and lays the groundwork for developing CORM-2 as a therapeutic agent for canine coagulopathies. Future studies will evaluate the effect of CORM-2 on whole blood both in vitro and in vivo. PMID- 29577636 TI - Time-lapse microscopy of oxidative stress demonstrates metabolic sensitivity of retinal pericytes under high glucose condition. AB - Hyperglycemia affects retinal vascular cell function, promotes the development and progression of diabetic retinopathy and ultimately causes vision loss. Oxidative stress, reactive oxygen species (ROS) in excess, is a key biomarker for diabetic retinopathy. Using time-lapse fluorescence microscopy, ROS dynamics was monitored and the metabolic resistivity of retinal endothelial cells (REC) and pericytes (RPC) was compared under metabolic stress conditions including high glucose (HG). In the presence of a mitochondrial stressor, REC exhibited a significant increase in the rate of ROS production compared with RPC. Thus, under normal glucose (NG), REC may utilize oxidative metabolism as the bioenergetic source, while RPC metabolic activity is independent of mitochondrial respiration. In HG condition, the rate of ROS production in RPC was significantly higher, whereas this rate remained unchanged in REC. Thus, under HG condition RPC may preferentially utilize oxidative metabolism, which results in increased rate of ROS production. In contrast, REC use glycolysis as their major bioenergetic source for ATP production, and consequently HG minimally affects their ROS levels. These observations are consistent with our previous studies where we showed HG condition has minimal effect on apoptosis of REC, but results in increased rate of apoptosis in RPC. Collectively, our results suggest that REC and RPC exhibit different metabolic activity preferences under different glucose conditions. Thus, protection of RPC from oxidative stress may provide an early point of intervention in development and progression of diabetic retinopathy. PMID- 29577637 TI - Patient's perspective on long-term complications after superficial parotidectomy for benign lesions: Prospective analysis of a 2-year follow-up. AB - OBJECTIVE: Evaluation of patients' perspective on long-term complications after superficial parotidectomy for benign lesions. DESIGN: A prospective nonrandomized controlled multicenter study. SETTING: Three university-based tertiary referral centers (Departments of Otorhinolaryngology of Cologne, Jena and Giessen; all in Germany). PARTICIPANTS: 130 adult patients, who underwent a primary superficial parotidectomy for benign tumors of the parotid gland, were consecutively included from 09/2010 to 05/2012. 61 patients completed every follow-up examination. MAIN OUTCOME MEASURES: Complications were evaluated using the validated German language questionnaire Parotidectomy Outcome Inventory 8 at six, 12 and 24 months after surgery. Pain intensity was assessed on a numeric rating scale (NRS) at each follow-up visit. RESULTS: At 6 months after surgery, 90% characterized hypoesthesia as the most disturbing problem, followed by fear of revision surgery (57%) and scar (56%). Facial palsy (14%) posed the minor problem. Hypoesthesia improved significantly during the follow-up period (all P < .05), but still posed a problem for 78% of the patients after 2 years. Pain, which initially bothered 53% of the patients, significantly decreased, whereas impairment due to Frey's syndrome significantly increased during the follow-up (6 vs 24 months; P = .002 and P = .001, respectively). Scar, substance loss, xerostomia, facial palsy, and anxiety affected patients with unvarying severity during the 2 years (all P > .05). CONCLUSIONS: From patients' perspective, sensation loss posed the major subjective problem after superficial parotidectomy. Appearance of the scar, and fear of revision surgery impaired more than 50% of the patients in their daily life without significant improvement during the 2 years postoperatively. Although superficial parotidectomy is a highly standardized and safe procedure, limited parotidectomy for proven benign parotid salivary gland neoplasms is more likely to result in patients with minimal or no displeasing complications. PMID- 29577638 TI - Upregulation of CXCR4 through promoter demethylation contributes to inflammatory hyperalgesia in rats. AB - AIM AND METHODS: Chronic pain associated with inflammation is a common clinical problem, and the underlying mechanisms yet are incompletely defined. DNA methylation has been implicated in the pathogenesis of chronic pain. However, the specific genes regulated by DNA methylation under inflammatory pain condition remain largely unknown. Here, we investigated how chemokine receptor CXCR4 expression is regulated by DNA methylation and how it contributes to inflammatory pain induced by complete Freund's adjuvant (CFA) in rats. RESULTS: Intraplantar injection of CFA could not only induce significant hyperalgesia in rats, but also significantly increase the expression of CXCR4 mRNA and protein in the dorsal root ganglion (DRG). Intrathecal injection of CXCR4 antagonist AMD3100 significantly relieved hyperalgesia in inflammatory rats in a time- and dose dependent manner. Bisulfite sequencing and methylation-specific PCR demonstrate that CFA injection led to a significant demethylation of CpG island at CXCR4 gene promoter. Consistently, the expression of DNMT3b was significantly downregulated after CFA injection. Online software prediction reveals three binding sites of p65 in the CpG island of CXCR4 gene promoter, which has confirmed by the chromatin immunoprecipitation assay, CFA treatment significantly increases the recruitment of p65 to CXCR4 gene promoter. Inhibition of NF-kB signaling using p65 inhibitor pyrrolidine dithiocarbamate significantly prevented the increases of the CXCR4 expression. CONCLUSION: Upregulation of CXCR4 expression due to promoter demethylation followed by increased recruitment of p65 to promoter of CXCR4 gene contributes to inflammatory hyperalgesia. These findings provide a theoretical basis for the treatment of chronic pain from an epigenetic perspective. PMID- 29577639 TI - A novel rapid quantitative method reveals stathmin-1 as a promising marker for esophageal squamous cell carcinoma. AB - Stathmin-1 is a microtubule depolymerization protein that regulates cell division, growth, migration, and invasion. Overexpression of stathmin-1 has been observed to be associated with metastasis, poor prognosis, and chemoresistance in various human cancers. Our previous studies found that serum stathmin-1 was significantly elevated in patients with esophageal squamous cell carcinoma (ESCC) by ELISAs. Here, we constructed high-affinity monoclonal antibodies and then developed a competitive AlphaLISA for rapid, accurate quantitation of stathmin-1 in serum. Compared to ELISA, our homogeneous AlphaLISA showed better sensitivity and accuracy, a lower limit of detection, and a wider linear range. The measurements of nearly 1000 clinical samples showed that serum stathmin-1 level increased dramatically in patients with squamous cell carcinoma (SCC), especially in ESCC, with a sensitivity and a specificity of 81% and 94%, respectively. Even for early stage ESCC, stathmin-1 achieved an area under the receiver operating characteristic curve (AUC) of 0.88. Meanwhile, raised concentrations of stathmin 1 were associated with lymph node metastasis and advanced cancer stage. Notably, various types of SCC showed significantly higher AUCs in serum stathmin-1 detection compared to adenocarcinoma. Furthermore, we confirmed that stathmin-1 was enriched in the oncogenic exosomes, which can explain the reason why it enters into the blood to serve as a tumor surrogate. In conclusion, this large scale and systematic study of serum stathmin-1 measured by our newly established AlphaLISA showed that stathmin-1 is a very promising diagnostic and predictive marker for SCC in the clinic, especially for ESCC. PMID- 29577640 TI - A Kv1.3 channel-specific blocker alleviates neurological impairment through inhibiting T-cell activation in experimental autoimmune encephalomyelitis. AB - AIM: Multiple sclerosis (MS) is a neurological autoimmune disorder characterized by mistaken attacks of inflammatory cells against the central nervous system (CNS), resulting in demyelination and axonal damage. Kv1.3 channel blockers can inhibit T-cell activation and have been designed for MS therapy. However, little is known about the effects of Kv1.3 blockers on protecting myelin sheaths/axons in MS. This study aimed at investigating the neuroprotection efficacy of a selective Kv1.3 channel blocker ImKTx88 (ImK) in MS animal model. METHODS: Experimental autoimmune encephalomyelitis (EAE) rat model was established. The neuroprotective effect of ImK was assessed by immunohistochemistry and transmission electron microscopy (TEM). In addition, the antiinflammatory effect of ImK by suppressing T-cell activation was assessed by flow cytometry and ELISA in vitro. RESULTS: Our results demonstrated that ImK administration ameliorated EAE clinical severity. Moreover, ImK increased oligodendrocytes survival, preserved axons, and myelin integrity and reduced the infiltration of activated T cells into the CNS. This protective effect of the peptide may be related to its suppression of autoantigen-specific T-cell activation via calcium influx inhibition. CONCLUSION: ImK prevents neurological damage by suppressing T-cell activation, suggesting the applicability of this peptide in MS therapy. PMID- 29577641 TI - Anthropometric Indices Based on Waist Circumference as Measures of Adiposity in Children. AB - OBJECTIVE: The aim of this study was to compare the accuracy of body fat patterns and single measures in assessing body fat and to clarify the use of indices based on waist circumference as measures of adiposity in children. METHODS: This study included 2,531 7-year-old children from the Generation XXI birth cohort (Porto, Portugal). Anthropometrics were obtained by trained personnel and whole-body dual energy x-ray absorptiometry (DXA) scans were performed. RESULTS: Principal component analysis identified two body fat patterns. Pattern 1 (BMI, fat mass index from tetra-polar bioelectric impedance, and waist-to-height ratio) showed strong correlations with DXA fat mass index (r = 0.85; P < 0.001), and pattern 2 (waist-to-hip, waist-to-thigh, and waist-to-weight ratios) showed moderate correlations with DXA central fat (r = 0.35; P < 0.001). Compared with single measures, body fat patterns showed similar correlations with DXA-derived measures. CONCLUSIONS: Compared with single anthropometric indices, body fat patterns seem to add little value for estimating body fat in children. Waist-to height ratio seems to be a proxy for total fat, while waist-to-hip, waist-to thigh, and waist-to-weight ratios seem to be proxies for central fat. Further studies should address the predictive ability of waist-to-weight ratio to identify children at risk of developing cardiometabolic disease, as this was the first time describing its potential usefulness. PMID- 29577642 TI - A simple, fast, and accurate thermodynamic-based approach for transfer and prediction of GC retention times between columns and instruments Part II: Estimation of target column geometry. AB - The transfer of thermodynamic parameters governing retention of a molecule in gas chromatography from a reference column to a target column is a difficult problem. Successful transfer demands a mechanism whereby the column geometries of both columns can be determined with high accuracy. This is the second part in a series of three papers. In Part I of this work we introduced a new approach to determine the actual effective geometry of a reference column and thermodynamic-based parameters of a suite of compounds on the column. Part II, presented here, illustrates the rapid estimation of the effective inner diameter (or length) and the effective phase ratio of a target column. The estimation model based on the principle of least squares; a fast Quasi-Newton optimization algorithm was developed to provide adequate computational speed. The model and optimization algorithm were tested and validated using simulated and experimental data. This study, together with the work in Parts I and III, demonstrates a method that improves the transferability of thermodynamic models of gas chromatography retention between gas chromatography columns. PMID- 29577643 TI - Susceptibilities of Candidatus Liberibacter asiaticus-infected and noninfected Diaphorina citri to entomopathogenic fungi and their detoxification enzyme activities under different temperatures. AB - Some entomopathogenic fungi species, Isaria fumosorosea, and Hirsutella citriformis were found to be efficient against the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae). However, the susceptibility to these fungi increases when the psyllid infected with Candidatus Liberibacter asiaticus (Las), which is transmitted by D. citri and causes citrus greening disease. In this study, we examined the Las-infected and Las-uninfected D. citri susceptibility to entomopathogenic fungi at different temperature regimes (5-40 degrees C). When D. citri adults exposed to cold temperature (5 degrees C), they showed less susceptibility to entomopathogenic fungi as compared with control (27 degrees C). Irrespective of infection with Las, a significantly positive correlation was observed between temperature and percentage mortality caused by different isolates of I. fumosorosea, 3A Ifr, 5F Ifr, PS Ifr, and H. citriformis isolates, HC3D and 2H. In contrast, a significantly negative correlation was found between temperature and percentage mortality for 3A Ifr for both Las infected and Las-uninfected psyllids. Detoxification enzymes, Glutathione S transferase levels in D. citri showed a negative correlation, whereas cytochrome P450 and general esterase levels were not correlated with changes in temperature. These findings revealed that detoxification enzymes and general esterase levels are not correlated with altered susceptibility to entomopathogenic fungi at the different temperature regimes. Conclusively, temperature fluctuations tested appear to be a significant factor impacting the management strategies of D. citri using entomopathogenic fungi.

AB - Immobilized trypsin (IM) has been recognized as an alternative to free trypsin (FT) for accelerating protein digestion 30 years ago. However, some questions of IM still need to be answered. How does the solid matrix of IM influence its preference for protein cleavage and how well can IM perform for deep bottom-up proteomics compared to FT? By analyzing Escherichia coli proteome samples digested with amine or carboxyl functionalized magnetic bead-based IM (IM-N or IM C) or FT, it is observed that IM-N with the nearly neutral solid matrix, IM-C with the negatively charged solid matrix, and FT have similar cleavage preference considering the microenvironment surrounding the cleavage sites. IM-N (15 min) and FT (12 h) both approach 9000 protein identifications (IDs) from a mouse brain proteome. Compared to FT, IM-N has no bias in the digestion of proteins that are involved in various biological processes, are located in different components of cells, have diverse functions, and are expressed in varying abundance. A high throughput bottom-up proteomics workflow comprising IM-N-based rapid protein cleavage and fast CZE-MS/MS enables the completion of protein sample preparation, CZE-MS/MS analysis, and data analysis in only 3 h, resulting in 1000 protein IDs from the mouse brain proteome.

AB - Bladder cancer becomes a serious medical and social concern due to its high recurrence and mortality rates. Thus, it is urgent to search a novel prognostic biomarker and targeted therapy with high sensitivity and specificity. In this study, we used the human bladder cancer cell line EJ as an immunogen to generate a novel mouse monoclonal antibody KMP1 that specifically bound to bladder cancer, and then, the antitumor effect of KMP1 against bladder cancer was investigated both in vivo and in vitro. The results showed that expression of the KMP1 epitope is consistent with clinical severity and prognosis of bladder cancer. Furthermore, KMP1 not only significantly inhibited the proliferation, migration, and adhesion of EJ cells in vivo, but also suppressed the xenograft tumor growth in nude mice compared with the control group treated with mIgG. Subsequently, the underlying mechanism of KMP1 against bladder cancer was explored via antigen affinity chromatography and mass spectrometry. CD44 located on the cytomembrane was found as the antigen of KMP1. Using RNA interference technology to knock down CD44 expression, we further identified that KMP1 has the antitumor activity by binding to CD44 and blocking its functions. In conclusion, KMP1 might be valuable for development as a promising specific diagnostic biomarker or targeted agent for bladder cancer. PMID- 29577647 TI - Long noncoding RNA LINC00152 is a potential prognostic biomarker in patients with high-grade glioma. AB - AIMS: To investigate the role of LINC00152 in high-grade glioma (HGG). METHODS: We collected data from the Chinese Glioma Genome Atlas (CGGA) microarray, CGGA RNA sequencing, and GSE16011 datasets to evaluate the expression and prognostic relationship of LINC00152 in patients with HGGs. A knockdown assay was performed to determine the function of LINC00152 in glioma development and progression in vitro and in vivo. RESULTS: The expression of LINC00152 was increased with glioma grade, especially in the mesenchymal TCGA subtype. LINC00152 was independently associated with poor prognosis, and the overall survival (OS) of the high expression group was shorter than the low expression group (median OS 14.77 vs 9.65 months; P = 0.0216) in the CGGA microarray dataset. The results were validated in the other 2 datasets. Based on the expression of LINC00152, 4288 (2519 positively; 1769 negatively) probes were extracted to perform a biological process analysis using the Database for Annotation, Visualization, and Integrated Discovery. Positively regulated genes were enriched in immune response, apoptotic process, cell adhesion, and regulation of cell proliferation. The clinical and molecular features of HGG patients indicated that patients in the LINC00152 high expression group tended to display the mesenchymal type, older (>=46 years), isocitrate dehydrogenase1 wild-type, O(6)-methylguanine DNA methyltransferase unmethylated, nonchemotherapy, and low karnofsky performance status. Functionally, knockdown of LINC00152 inhibited cell proliferation, migration, and invasion and increased the sensitivity of chemotherapy in vitro. CONCLUSION: Our results indicate that knockdown of LINC00152 could inhibit tumor growth in vivo. LINC00152 could serve as a potential prognostic biomarker in patients with HGG.

AB - INTRODUCTION: The age of patients with gastric cancer has increased worldwide. The aim of this study was to investigate the safety and feasibility of laparoscopic gastrectomy (LG) for early gastric cancer in elderly patients. METHODS: We retrospectively investigated 221 consecutive patients who underwent LG for early gastric cancer during a 5-year period (January 2010 to December 2014). We divided the patients into two groups: elderly patients (>=75 years old) and younger patients (<75 years old). We compared these two groups with respect to clinical characteristics, histopathological findings, intraoperative factors, and postoperative outcomes. RESULTS: The preoperative characteristics were similar in both groups. Except for the number of harvested lymph nodes (42.0 vs 34.9; P = 0.0016), the short-term operative outcomes, including postoperative complications and histopathological findings, were comparable between the two groups. Although significantly fewer lymph nodes were harvested in the elderly group, the overall survival and relapse-free survival rates did not significantly differ between the groups. Postoperative complications, such as acute cholecystitis and internal hernia, occurred during the long-term postoperative period after LG, and these unexpected complications were more frequently observed in elderly patients. All elderly patients required additional emergent surgeries for delayed complications. CONCLUSION: The outcomes of LG for early gastric cancer in elderly patients seem to be reasonable. Aggressive lymph node dissection may be omissible in elderly patients with acceptable results. LG can be a safe and feasible procedure in elderly patients. However, the higher rate of delayed but urgent complications during the long-term postoperative period must be considered.

AB - The cytological examination of cavity fluids has limited sensitivity in the diagnosis of malignancy. Aneuploidy, which is commonly observed in neoplastic cells, could potentially be used as an ancillary diagnostic tool. To evaluate the detection of aneuploid cells in cavitary effusion samples using the fluorescence in situ hybridization (FISH) assay UroVysion(r) with some adaptations and two different cutoff strategies. Seventy samples of pleural or peritoneal fluid with positive (n = 40), negative (n = 15), or suspicious (n = 15) oncotic cytology were subjected to FISH assay with the multitarget UroVysion(r) kit, which is composed of probes that hybridize to the centromeric region of chromosomes 3, 7, and 17 and to the locus 9p21. FISH performance was evaluated using two different cutoffs: (1) the manufacturer's cutoff (M-FISH) and 2) a proposed cutoff (P FISH). Using M-FISH, the diagnostic sensitivity was 57.1%, specificity 87.5%, and accuracy 60.0%; with P-FISH, the sensitivity was 87.3%, specificity 71.4%, and accuracy 85.7%. When combined with cytology, the sensitivity, specificity, and accuracy were 88.0%, 83.3%, and 87.8%, respectively. Malignant cells presented a predominance of chromosomal gains. The UroVysion(r) test using the P-FISH cutoff was effective in demonstrating aneuploid cells in all malignant effusions, confirming the diagnosis of malignancy even in cases with suspicious cytology.

PMID- 29577649 TI - Exopolysaccharides from a Codonopsis pilosula endophyte activate macrophages and inhibit cancer cell proliferation and migration. AB - BACKGROUND: Exopolysaccharides with structural diversity have shown wide applications in biomaterial, food, and pharmaceutical industries. Herein, we isolated an endophytic strain, 14-DS-1, from the traditional medicinal plant Codonopsis pilosula to elucidate the characteristics and anti-cancer activities of purified exopolysaccharides. METHODS: HPLC and GC-MS were conducted to purify and characterize the exopolysaccharides isolated from 14-DS-1. Quantitative RT PCR, cell migration assays, immunofluorescence staining, and flow cytometry analysis were conducted to investighate the biological activity of DSPS. RESULTS: We demonstrated that exopolysaccharides isolated from 14-DS-1 (DSPS), which were predominately composed of six monosaccharides, showed anti-cancer activities. Biological activity analysis revealed that exposure to DSPS induced macrophage activation and polarization by promoting the production of TNF-alpha and nitric oxide. Further analysis revealed that DSPS treatment promoted macrophage infiltration, whereas cancer cell migration was suppressed. In addition, DSPS exposure led to S-phase arrest and apoptosis in cancer cells. Immunofluorescence staining revealed that treatment with DSPS resulted in defects in spindle orientation and positioning. CONCLUSION: These findings thus suggest that DSPS may have promising potential in cancer therapy. PMID- 29577651 TI - Prostate-specific antigen nadir within 12 months as an early surrogate marker of biochemical failure and distant metastasis after low-dose-rate brachytherapy or external beam radiotherapy for localized prostate cancer. AB - Prostate-specific antigen nadir (nPSA) after radiotherapy for localized prostate cancer has been investigated as a predictor. However, nPSA usually requires several years, limiting its clinical utility. We investigated the significance of nPSA within 12 months (nPSA12) after low-dose-rate prostate brachytherapy (LDR PB) or external beam radiotherapy (EBRT) on treatment outcomes. Between 2006 and 2014, 663 patients with prostate cancer were treated with LDR-PB or EBRT at two institutions. Four hundred and seventy-four men received LDR-PB and 189 men received EBRT, without androgen deprivation therapy. The Kaplan-Meier method was used for biochemical failure (BF)-free survival (BFFS) and distant metastasis (DM)-free survival (DMFS) analyses, and multivariable Cox regression analysis was performed. The median follow-up was 61.3 months. The median nPSA12 in the LDR-PB and EBRT cohorts was 0.7 and 1.0 ng/mL, respectively. The 7-year BFFS and DMFS rates in LDR-PB patients with nPSA12 <= 0.7 ng/mL were 99.1% and 99.5%, respectively; when nPSA12 was >0.7 ng/mL, they were 90.2% and 94.8%, respectively. In EBRT patients with nPSA12 <= 1.0 ng/mL, BFFS and DMFS rates were 85.4% and 98.5%, respectively; when nPSA12 was >1.0 ng/mL, they were 67.1% and 87.2%, respectively. nPSA12 was an independent predictor of BF and DM in both cohorts (LDR-PB, P = 0.004 and 0.020, respectively; EBRT, P = 0.005 and 0.041, respectively). The nPSA12 after LDR-PB or EBRT is significantly associated with treatment outcomes of prostate cancer. Higher nPSA12 may identify patients at high risk of relapse who might benefit from salvage treatment. PMID- 29577652 TI - Preliminary study of the homologous recombination repair pathway in mouse spermatogonial stem cells. AB - The present study was designed to detect DNA repair response through the homologous recombination pathway in mouse spermatogonial stem cells. Mouse spermatogonial stem cells (mSSCs) were obtained from the adult DBA/2 mouse testes by MACS sorting. mSSCs and mice animals were divided into four groups (30 min, 2, 24 h, control) and treated with ionizing irradiation while the control group received pseudo-irradiation. Proteins involved in the homologous recombination pathway (gammaH2AX, ATM, RAD51, CtIP, and RPA2) were assessed in mSSCs both in vitro and in vivo. Moreover, the non-homologous end-joining or homologous recombination (NHEJ/HR) reporter plasmids were transfected into mSSCs to assess NHEJ/HR pathway activity after DNA double-strand break (DSB). gammaH2AX, a classical DNA DSB marker, was absent in mSSCs both in vivo and in vitro after DSB repair, but was highly expressed in other tissue stem cells. In addition, ATM and phosphorylated ATM (p-ATM) were involved in DNA damage response (DDR) in mSSCs. p ATM foci were overexpressed immediately after irradiation (30 min and 2 h), but gradually decreased over the repair time. The HR pathway-related proteins, CtIP and RPA2 were negatively regulated after treatment in Western blot (WB). NHEJ/HR reporter plasmid transfection indicated that the HR pathway played a minor role in mSSCs during DDR, consistent with the WB findings. This study demonstrates that mSSCs may have a unique response to DNA damage since crucial proteins involved in HR pathway were negatively regulated after DSB. In addition, the expression level of p-ATM, but not gammaH2AX, was increased after DSB, suggesting that DNA damage repair in mSSCs might be a gammaH2AX-independent response. Furthermore, the HR pathway may play a minor role during DDR in mSSCs.

AB - An imino bipyridine cobalt(II) complex was developed for the electrocatalytic reduction of CO2 to formate in acetonitrile with a faradaic efficiency of approximately 80 %. For comparison, a symmetric bis-imino pyridine complex showed lower catalytic activity because of less conjugation in the system. Cyclic voltammetry, electron paramagnetic resonance and IR spectroscopy studies provided mechanistic details and the structures of the key intermediates. DFT calculations confirmed the role of large pi-conjugated groups for stabilizing key intermediates through electronic conjugation. PMID- 29577656 TI - Detecting the effect of bisphosphonates during osteoporosis treatment on jawbones using multidetector computed tomography: The OSTEOSYR project. AB - AIM: The aim of the present cross-sectional study was to investigate the effects of bisphosphonates (BP), prescribed for osteoporosis, on jawbones using multidetector computed tomography (MDCT). METHODS: Fifty-three women who had dual energy X-ray absorptiometry examination were scanned by MDCT. Both the cortical and the trabecular parts of the alveolar and the cortical bones were compared between BP users and non-BP users using a number of radiological measurements. Linear regression was used for the statistical analysis. RESULTS: The cortical part of the basal bone of the mandible revealed a significant increase in the BP group (.001 > P-value <= .026) after using BP for 5 years. No alternations were observed in the trabecular part of the basal bone or in the cortical or trabecular parts of the alveolar bone over the same duration. CONCLUSIONS: The use of BP as a treatment for osteoporosis for 5 years increased the thickness of the cortex of the basal bone of the mandible, as detected by MDCT. The other parts of the jawbones showed no influence by BP for such a purpose, as detected on MDCT images. Accordingly, models (equations) for predicting the alternations in the inferior cortex of the mandible induced by BP therapy during osteoporosis have been suggested.

AB - Zoonotic transmission of Salmonella infections causes an estimated 11% of salmonellosis annually in the United States. This report describes the epidemiologic, traceback and laboratory investigations conducted in the United States as part of four multistate outbreaks of Salmonella infections linked to small turtles. Salmonella isolates indistinguishable from the outbreak strains were isolated from a total of 143 ill people in the United States, pet turtles, and pond water samples collected from turtle farm A, as well as ill people from Chile and Luxembourg. Almost half (45%) of infections occurred in children aged <5 years, underscoring the importance of the Centers for Disease Control and Prevention recommendation to keep pet turtles and other reptiles out of homes and childcare settings with young children. Although only 43% of the ill people who reported turtle exposure provided purchase information, most small turtles were purchased from flea markets or street vendors, which made it difficult to locate the vendor, trace the turtles to a farm of origin, provide education and enforce the United States federal ban on the sale and distribution of small turtles. These outbreaks highlight the importance of improving public awareness and education about the risk of Salmonella from small turtles not only in the United States but also worldwide. PMID- 29577655 TI - First insights into Puumala orthohantavirus circulation in a rodent population in Alsace, France. AB - In-depth knowledge on the mechanisms that maintain infection by a zoonotic pathogen in an animal reservoir is the key to predicting and preventing transmission to humans. The Puumala orthohantavirus (PUUV), the most prevalent orthohantavirus in Western Europe, causes a mild form of haemorrhagic fever with renal syndrome (HFRS) in humans. In France, this endemic illness affects the north-eastern part of the country. We conducted a 4-year capture-mark-recapture study in a bank vole population, combined with molecular analyses, to explore the epidemiological situation of PUUV in Alsace, a French region where human cases have occurred, but for which no studies have been conducted on this reservoir host. PUUV-infected bank voles were detected in the 2 years that showed high bank vole density with a prevalence of 4%. The individual PUUV sequences identified in this study were similar from year to year and similar to other French sequences. On a very small spatial scale, the distribution of seropositive bank voles was very heterogeneous in time and space. The short distances travelled on average by bank voles resulted in spatial clusters of seropositive rodents, which spread only very gradually throughout the year. PMID- 29577657 TI - Fast uncertainty quantification of activation sequences in patient-specific cardiac electrophysiology meeting clinical time constraints. AB - We present a fast, patient-specific methodology for uncertainty quantification in electrophysiology, aimed at meeting the time constraints of clinical practitioners. We focus on computing the statistics of the activation map, given the uncertainties associated with the conductivity tensor modeling the fiber orientation in the heart. We use a fast parallel solution method implemented on a graphics processing unit for the eikonal approximation, in order to compute the activation map and to sample the random fiber field with correlation on the basis of geodesic distances. While this enables to perform uncertainty quantification studies with a manageable computational effort, the required time frame still exceeds clinically suitable time expectations. In order to reduce it further by 2 orders of magnitude, we rely on Bayesian multifidelity methods. In particular, we propose a low-fidelity model that is patient-specific and free from the additional training cost associated with reduced models. This is achieved by a sound physics-based simplification of the full eikonal model. The low-fidelity output is then corrected by the standard multifidelity framework. In practice, the complete procedure only requires approximately 100 new runs of our eikonal graphics processing unit solver for producing the sought estimates and their associated credible intervals, enabling a full online analysis in less than 5 minutes. PMID- 29577658 TI - Metabolism study for CUMYL-4CN-BINACA in human hepatocytes and authentic urine specimens: Free cyanide is formed during the main metabolic pathway. AB - To further elucidate the metabolism of CUMYL-4CN-BINACA, a new synthetic cannabinoid with a cyano group, and to evaluate biomarkers, we incubated the substance in human hepatocytes and analysed 9 authentic urine specimens. We also quantified CUMYL-4CN-BINACA and cyanide in blood and provide comprehensive data on the 7 autopsy cases, 5 of them determined CUMYL-4CN-BINACA intoxications. For metabolite elucidation, CUMYL-4CN-BINACA was incubated with pooled human hepatocytes for up to 5 hours, urine samples were analysed with and without enzymatic hydrolysis. Data was acquired in data-dependent mode by ultra-high performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS) with an Agilent 6550 QTOF. For quantitative analysis of CUMYL-4CN-BINACA, blood samples were precipitated and analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Cyanide was determined by gas chromatography-headspace nitrogen phosphorus detection (GC-headspace-NPD). CUMYL-4CN-BINACA was metabolised via CYP450-mediated hydroxylation at 4-butyl position generating a cyanohydrin (M12), which releases free cyanide to form an aldehyde intermediate and eventually generates 4-hydroxybutyl CUMYL-BINACA (M11) and CUMYL-BINACA butanoic acid (M10). Other minor metabolites were produced by hydroxylation, dihydroxylation, N-dealkylation, and dihydrodiol formation; glucuronidation was observed. One urine sample showed high intensities of M10 and a wide variety of metabolites; the other samples contained fewer metabolites in low abundance and 1 sample showed no metabolites. CUMYL-4CN-BINACA blood concentrations ranged from 0.1 to 8.3 ng/g showing an overlap between fatal and non-fatal concentrations. One blood sample contained 0.36 MUg/g cyanide. Release of free cyanide during metabolism is worrying as it might induce liver toxicity. As suggested earlier, CUMYL-BINACA butanoic acid is the most abundant biomarker in urine, but monitoring of additional metabolites or, even better, analysis for the parent in blood is recommended. PMID- 29577659 TI - Trajectories of change in symptom distress in a clinical group of late adolescents: The role of maladaptive personality traits and relations with parents. AB - In this study, it was analysed whether trajectories of change in symptom distress could be identified in a clinical group of late adolescents with personality pathology. Furthermore, it was examined whether maladaptive personality traits and relations with parents were predictive of following one of these trajectories. Three latent classes emerged from growth mixture modelling with a symptom inventory (n = 911): a Stable High, a Strong Decreasing and a Moderate Decreasing trajectory. Subsequently, by using multinomial logistic regression analyses in a subsample of late-adolescents (n = 127), it was revealed that high levels of Negative Affectivity and Detachment were predictive of following the Strong Decreasing, and high levels of Detachment were predictive of following the Stable High trajectory. Support from or Negative Interactions with parents were not predictive of any of the trajectories. The current results contribute to the notion of individual trajectories of change in symptom distress and provide suggestions for screening patients on personality traits to gain insight in the course of this change.

PMID- 29577661 TI - Cross-sectional study to estimate the prevalence of enterohaemorrhagic Escherichia coli on hides of market beef cows at harvest. AB - Cattle hides are an important source of enterohaemorrhagic Escherichia coli (EHEC) carcass contamination at slaughter. Seven EHEC serogroups are adulterants in raw, non-intact beef: EHEC O26, O45, O103, O111, O121, O145 and O157. The objective of this study was to estimate the probability for hide contamination with EHEC among US market beef cows at slaughter and to test the effects of season and geographic region on prevalence of hide contamination. Hides (n = 800) of market cows were swabbed at slaughter immediately after exsanguination, prior to hide removal. Cows were sampled from two geographically distinct beef packing plants during four seasons of 2015. Cattle source was categorized by northern or southern region. Samples were tested for EHEC by a molecular screening assay. The effects of region, season and their interaction on the probability of hide contamination by each EHEC serogroup were tested in separate multilevel multivariable logistic regression models, accounting for the random effect of clustering by plant. Statistical significance was set alpha = .05. Of 800 total samples, at least one EHEC was detected on 630 (79%) hides. Enterohaemorrhagic E. coli O26 was detected on 129 (16%) of all hides sampled, EHEC O45 on 437 (55%), EHEC O103 on 289 (36%), EHEC O111 on 189 (24%), EHEC O121 on 140 (18%), EHEC O145 on 171 (21%) and EHEC O157 on 89 (11%). Detection of EHEC O26 and EHEC O121 was associated with season. Season and region were associated with detecting EHEC O45 and EHEC O157. Season-by-region interactions were associated with the outcome of detecting EHEC O103, EHEC O111 and EHEC O145. Season, region of origin and the interaction of these factors affect hide contamination of market beef cattle at slaughter by EHEC, and each serogroup responds to these factors uniquely.

AB - In contrast to most lab-scale batch procedures, a continuous-flow implementation requires a thorough consideration of the solid catalyst design. In a previous study, irregular zeolite pellets were applied in a miniaturized continuous-flow reactor for the Diels-Alder reaction in the construction of norbornene scaffolds. After having faced the challenges of continuous operation, the aim of this study is to exploit catalyst structuring. To this end, microspheres with high uniformity and various sphere diameters were synthesized according to the vibrational droplet coagulation method. The influence of the use of these novel zeolite shapes in a mesoscale continuous-flow Diels-Alder process of cyclopentadiene and methyl acrylate is discussed. An impressive enhancement of catalyst lifetime is demonstrated, as even after a doubled process time of 14 h, the microspheres still exceeded the conversion after 7 h when using zeolite pellets by 30 %. A dual reason is found for this beneficial impact of catalyst shaping. The significant improvement in catalyst longevity can be attributed to the interplay of the chemical composition and the porosity structure of the microspheres. PMID- 29577663 TI - Inhibition of breast cancer cell growth by methyl pyropheophenylchlorin photodynamic therapy is mediated though endoplasmic reticulum stress-induced autophagy in vitro and vivo. AB - Autophagy and ER stress participated in the inhibition of MPPa-PDT on tumor growth, but the molecular links between them remain undefined. We just explore the molecular mechanism between them in vitro and vivo. CCK-8 assay and flow cytometer were used to detect the cytotoxicity and mode of cell death after MPPa PDT. Furthermore, the role of autophagy was verified in MPPa-PDT. Confocal microscopy was used to show the intracellular distribution of MPPa. ER stress markers and PERK signaling pathway were detected by western blot. While in vivo, tumor histology and immunohistochemistry were performed to show the effect of MPPa-PDT in mice. After MPPa-PDT, cells viability decreased in dose-dependent manner. Besides, the cell apoptosis increased along with the increasing of Beclin 1and LC3B II but declining of P62. When pretreated with 3-MA, LC3B II formation and the cytotoxicity declined. MPPa-PDT caused increasing of ER stress markers (GRP78, CHOP) as MPPa accumulated in ER. However, pretreatment with ER stress inhibitor 4PBA, the expression of GRP78 and LC3B II was blocked but the PERK signaling pathway activated and the expression of P62 increased. In vivo, the tumor growth was significantly inhibited by MPPa-PDT. Besides, the appearance of ER stress and autophagy was further demonstrated by immunohistochemistry. Our findings demonstrate that autophagy mediated by MPPa-PDT was regulated by ER stress, via PERK signaling pathway, to kill MDA-MB-231 cells in vitro and vivo. PMID- 29577664 TI - Risk of thyroid cancer in relation to height, weight, and body mass index in Japanese individuals: a population-based cohort study. AB - Greater height and body mass index (BMI) have been associated with an increased risk of thyroid cancer incidence in Western countries. However, few epidemiological studies have assessed the association between anthropometric factors, such as BMI, height, or weight, and thyroid cancer incidence in Asian populations. Using the population-based Japan Public Health Center-based prospective study database, we investigated the relationship between anthropometric factors and thyroid cancer incidence. Data on anthropometric factors were collected through a self-administered questionnaire at baseline. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the Cox proportional hazards model, and the exposure level was categorized into quintiles. A total of 49,062 men and 53,661 women enrolled between 1990 and 1994 were included in our analyses, and 191 cases (37 in men and 154 in women) of thyroid cancer were identified, with 1,695,702 person-years of follow-up until 2010. Compared with the male group with height <=160 cm, HRs of the male groups with height 165-168 cm and >=169 cm were 3.92 (95% CI; 1.33-11.55, P = 0.013) and 4.24 (95% CI; 1.32-13.61, P = 0.015), respectively, and the HR per 5-cm increase in height was 1.12 (95% CI 1.06-1.18, P < 0.001). In contrast, the association between anthropometric features and the risk of thyroid cancer did not significantly differ among women. In this population, an increase in risk for increased height was observed in men, but no associations between anthropometric indexes and thyroid cancer risk were observed in women. PMID- 29577665 TI - Relevance of Local Flexibility Near the Active Site for Enzymatic Catalysis: Biochemical Characterization and Engineering of Cellulase Cel5A From Bacillus agaradherans. AB - Detailed molecular mechanisms underpinning enzymatic reactions are still a central problem in biochemistry. The need for active site flexibility to sustain catalytic activity constitutes a notion of wide acceptance, although its direct influence remains to be fully understood. With the aim of studying the relationship between structural dynamics and enzyme catalysis, the cellulase Cel5A from Bacillus agaradherans is used as a model for in silico comparative analysis with mesophilic and psychrophilic counterparts. Structural features that determine flexibility are related to kinetic and thermodynamic parameters of catalysis. As a result, three specific positions in the vicinity of the active site of Cel5A are selected for protein engineering via site-directed mutagenesis. Three Cel5A variants are generated, N141L, A137Y and I102A/A137Y, showing a concomitant increase in the catalytic activity at low temperatures and a decrease in activation energy and activation enthalpy, similar to cold-active enzymes. These results are interpreted in structural terms by molecular dynamics simulations, showing that disrupting a hydrogen bond network in the vicinity of the active site increases local flexibility. These results provide a structural framework for explaining the changes in thermodynamic parameters observed between homologous enzymes with varying temperature adaptations.

AB - Bioconjugation of enzymes on coatings based on polydopamine (PDA) layers is an appealing approach to control biological responses on biomedical implant surfaces. As alternative to PDA wet deposition, a fast, solvent-free, and dynamic deposition approach based on atmospheric-pressure plasma dielectric barrier discharge process is considered to deposit on metallic surfaces acrylic-based interlayers containing highly chemically reactive catechol/quinone groups. A biomimetic approach based on covalent immobilization of Dispersin B, an enzyme with antibiofilm properties, shows the bioconjugation potential of the novel plasma polymer layers. The excellent antibiofilm activity against Staphylococcus epidermidis is comparable to the PDA-based layers prepared by wet chemical methods with slow deposition rates. A study of preosteoblastic MG-63 human cell line viability and adhesion properties on plasma polymer layers demonstrates early interaction required for biomedical applications.

AB - Many conditions have to be optimized in order to be able to grow the cyanobacterium Synechocystis sp. PCC 6803 (Synechocystis) for an extended period of time under physiologically well-defined and constant conditions. It is still poorly understood what limits growth of this organism in batch and continuous cultures in BG-11, the standard medium used to grow Synechocystis. Through a series of batch experiments in flasks and continuous mode experiments in advanced photobioreactors, it is shown that the limiting nutrient during batch cultivation is sulfate, the depletion of which leads to ROS formation and rapid bleaching of pigments after entry into stationary phase. In continuous mode, however, the limiting nutrient is iron. Optimizing these growth conditions resulted in a so far highest growth rate of 0.16 h-1 (4.3 h doubling time), which is significantly higher than the textbook value of 0.09 h-1 (8 h doubling time). An improved medium, BG-11 for prolonged cultivation (BG-11-PC) is introduced, that allows for controlled, extended cultivation of Synechocystis, under well-defined physiological conditions. The data present here have implications for mass culturing of cyanobacteria.

AB - Recent reports have shown that food-borne or commensal bacteria can function as reservoirs of antibiotic resistance. However, the antibiotic susceptibility of bacterial isolates of most milk samples or the total bacterial counts (TBC) in human milk from healthy donors, are not fully understood in Taiwan. Thus, five healthy mothers were randomly recruited each month, and totally 30 mothers without any symptoms of infection were recruited over 6 months. Milk samples were then harvested and analyzed immediately after collection. The antibiotic susceptibility was analyzed in bacteria isolated from milk samples using nine clinically relevant antibiotics, such as oxacillin, ampicillin, cephalothin, amoxicillin, ciprofloxacin, erythromycin, clindamycin, gentamicin, and oxytetracycline. The Staphylococcus strains (48 isolates) found in milk resisted to 48.6 +/- 20.1% selected antibiotics. Streptococcus-related isolates (8 isolates) exhibited resistance to 41.7 +/- 26.4% selected antibiotics. Acinetobacter isolates (5 isolates) were resistant to 66.7 +/- 13.6% antibiotics, and Enterococcus isolates (5 isolates) were resistant to 73.3 +/- 6.1% tested antibiotics. Rothia-related isolates (4 isolates) were resisted to 58.2 +/- 31.9% of tested antibiotics. In contrast, Corynebacterium isolates (5 isolates) were sensitive to 66%-100% of selected antibiotics. Furthermore, the TBC ranged from 40 to 710,000 CFU/ml, implying a wide spectrum of bacteria in milk from healthy mothers. Despite this, all milk donors were healthy during sampling, and they did not show any symptoms related to mastitis or subclinical mastitis. According to the previously described TBC criteria for the use of donated human milk, only 73% of the current milk samples could be accepted for the milk bank. In conclusion, the majority of the isolated bacterial strains from current human milk samples are multiresistant strains. In milk samples for preterm infants or milk banks, higher TBC levels or potentially antibiotic-resistant bacteria in some milk samples have supported people using approaches to disinfect human milk partially.

AB - The nuclear factor I (NFI) family members, especially NFIA and NFIB, play essential roles in cancers. The roles of NFIA and NFIB in esophageal squamous cell carcinoma (ESCC) and esophagogastric junction adenocarcinoma (EJA) remain poorly known. This study aimed to determine the expression of NFIA and NFIB in ESCC and EJA and elucidate their prognostic significance. The expression of NFIA and NFIB was examined in 163 ESCC samples and 26 EJA samples by immunohistochemistry. The results showed that high NFIA expression correlated significantly with poor differentiation, lymph node metastasis, and advanced TNM stage in patients with ESCC. High NFIB expression only correlated with poor differentiation in patients with ESCC. Survival analysis showed that NFIA but not NFIB associated with short overall survival (OS) and disease-free survival (DFS) of patients with ESCC. On the other hand, high NFIB expression correlated with lymph node metastasis, advanced TNM stage, and short OS and DFS in patients with EJA. Finally, multivariate analysis demonstrated that high NFIA expression was an independent prognostic factor for ESCC. Taken together, these results demonstrated that NFIA and NFIB could serve as prognostic indicators for ESCC and EJA, respectively. PMID- 29577672 TI - Cancer risk in patients with alopecia areata: a nationwide population-based matched cohort study. AB - Alopecia areata (AA) is an organ-specific autoimmune disorder. Defective immune system related disorders are prone to increase the risk of cancer formation. However, the association among AA and variety of cancer types had never been studied. A nationwide population-based matched cohort study was conducted to evaluate the cancer risk in patients with AA. Records from Taiwan National Health Insurance Research Database were analyzed. Cases of AA from 1997 to 2013 and cancers registered in the catastrophic illness profile from the same time period were collected. The standard incidence ratio (SIR) of each cancer was calculated. In total, 2099 cancers among 162,499 patients with AA and without prior cancers were identified. The overall cancer risks in AA patients were slightly decreased, especially among male subjects (SIR: 0.89). Refer to individual cancer, the cancer risk of nonmelanoma skin cancer (NMSC) (SIR: 0.59), upper GI cancer (SIR: 0.70), liver cancer (SIR: 0.82), uterine, and cervix cancer (SIR: 0.84) were significantly lower in patients with AA. In contrast, AA patients were inclined to have lymphoma, breast cancer, kidney, and urinary bladder cancer with the SIR of 1.55, 2.93, and 2.95, respectively. Age stratified analyses revealed female AA patients younger than 50 years old have even higher risk of breast cancer (SIR: 3.37). Further sensitivity analysis showed similar results after excluding major autoimmune disorders. Cancer risk in AA patients is organ specific, and it is not associated with the underlying autoimmune disorders in patients with AA.

AB - Elevated levels of arsenic (As) in aquifers of South East Asia have caused diverse health problems affecting millions of people who drink As-rich groundwater and consume various contaminated agriculture products. The biogeochemical cycling and mobilization/immobilization of As from its mineral bound phase is controlled by pH, oxic/anoxic conditions, and different microbial processes. The increased As flux generated from ongoing biogeochemical processes in the subsurface in turn affects the in situ microbial communities. This study analyzes how the indigenous arsenite-oxidizing bacteria combat As stress by various biophysical alterations and self-adaptation mechanisms. Fifteen arsenite oxidizing bacterial strains were isolated and identified using a polyphasic approach. The bacterial strains isolated from these aquifers belong predominantly to arsenite-oxidizing bacterial groups. Of these, the membrane-bound phospholipid fatty acids (PLFA) were characterized in seven selected bacterial isolates grown at different concentrations of As(III) in the medium. One of the significant findings of this study is how the increase in external stress can induce alteration of membrane PLFAs. The change in fatty acid saturation and alteration of their steric conformation suggests alteration of membrane fluidity due to change in As-related stress. However, different bacterial groups can have different degrees of alteration that can affect sustainability in As-rich aquifers of the Bengal Delta Plain.

AB - Although nilotinib has improved efficacy compared to imatinib, suboptimal response and intolerable adverse events (AEs) limit its effectiveness in many patients with chronic myeloid leukemia in chronic phase (CML-CP). We investigated the 2-year efficacy and safety of nilotinib and their relationships with plasma nilotinib concentrations (PNCs). In this open-label, multi-institutional phase 4 study, 110 Philadelphia chromosome-positive CML-CP patients were treated with nilotinib at a starting dose of 300 mg twice daily. Molecular responses (MRs) and AEs were monitored for up to 24 months. The 24-month cumulative MR4.5 rate was evaluated as the primary endpoint. Plasma samples were collected from 94 patients to determine PNCs, and the per-patient mean was used to categorize them into four mean PNC (MPNC) groups. Cumulative MR rates and safety were compared between groups. With a median follow-up of 22.2 months, the 24-month cumulative MR4.5 rate was 56.2% (95% confidence interval, 44.0%-8.3%), and the median time to MR4.5 was 23.3 months. There were no significant differences in the cumulative rates of major molecular response, MR4 , and MR4.5 between MPNC groups. One patient died due to acute viral hepatitis, and two developed hematological or cytogenetic relapse, while no progression to accelerated or blast phase was observed. Safety results were consistent with previous studies with no new safety signal identified. Across the MPNC groups, there was no significant linear trend in the frequency of AEs. Nilotinib is highly effective for the treatment of CML CP with manageable AEs. The measurement of PNC has no predictive value for patient outcomes and is thus not found to be clinically useful. This study is registered with clinicaltrials.gov, Number NCT03332511. PMID- 29577676 TI - Superficial radiotherapy as a treatment alternative for recurrent conjunctival squamous cell carcinoma: a case study. AB - This case study discusses the use of superficial radiotherapy (SXRT) in the treatment of recurrent conjunctival squamous cell carcinoma (SCC). Conjunctival SCC is often an aggressive cancer, with surgery the current standard of care. There is currently limited literature on alternative treatment options to treat conjunctival SCC recurrences that enable ocular function preservation. Furthermore, the use of SXRT in this setting is not well-reported. Technical feasibility, practical limitations and potential side effects of SXRT (in comparison to other treatment options) are discussed in this case study. This case describes a 62 years old male with limited treatment options following multiple recurrences of conjunctival SCC. He was prescribed a therapeutic SXRT dose of 48.4 Gy in 22 fractions (5 fractions/week). At 6-month follow-up, there was no evidence of residual or recurrent disease, or any significant objective or patient reported treatment induced side effects. This case study provides preliminary evidence for the potential application of SXRT for conjunctival SCC. The benefits reported in this case study warrant further investigation of the applicability of SXRT in a larger patient cohort, with the potential to provide patients with a less invasive treatment alternative for recurrent conjunctival SCC. PMID- 29577677 TI - Phase determination using chromosomal microarray and fluorescence in situ hybridization in a patient with early onset Parkinson disease and two deletions in PRKN. AB - BACKGROUND: Mutations in the parkin gene (PRKN) are the most commonly identified genetic factors in early onset Parkinson disease (EOPD), with biallelic mutations, resulting in a clinical phenotype. However, normal variation is also common in PRKN, particularly in the form of copy number variation (CNV), challenging interpretation of genetic testing results. Here we report a case of a 29-year-old male with EOPD and two deletions in PRKN detected by chromosomal microarray (CMA). METHODS: The proband was clinically examined by a neurologist for postural instability with frequent falls, bradykinesia, gait freezing with festination, and hypophonia. Chromosomal microarray analysis (CMA) was performed on the proband and his parents using the Affymetrix CytoScan HD microarray. Subsequent fluorescence in situ hybridization (FISH) was performed on the proband and both parents. RESULTS: Chromosomal microarray detected the presence of two deletions of PRKN in the proband. Parental CMA analysis was performed to determine the clinical significance of this finding, as well as to demonstrate phase of these deletions. Parental CMA revealed that one deletion was paternally inherited and one deletion was de novo. A custom FISH approach was then successfully used to phase the deletions. CONCLUSION: Chromosomal microarray and fluorescence in situ hybridization analysis of this trio identified two deletions in PRKN occurring in trans, providing a genetic etiology for the clinical diagnosis of EOPD. The determination of inheritance and phase of the deletions was critical to the proper interpretation of these results. These findings highlight the utility of CMA in the detection of clinically relevant CNVs in cases of EOPD, and also serve to emphasize the importance of follow-up FISH and parental testing.

AB - Material systems that exhibit tailored interactions with cells are a cornerstone of biomaterial and tissue engineering technologies. One method of achieving these tailored interactions is to biofunctionalize materials with peptide ligands that bind integrin receptors present on the cell surface. However, cell biology research has illustrated that both integrin binding and integrin clustering are required to achieve a full adhesion response. This biophysical knowledge has motivated researchers to develop material systems biofunctionalized with nanoscale clusters of ligands that promote both integrin occupancy and clustering of the receptors. These materials have improved a wide variety of biological interactions in vitro including cell adhesion, proliferation, migration speed, gene expression, and stem cell differentiation; and improved in vivo outcomes including increased angiogenesis, tissue healing, and biomedical device integration. This review first introduces the techniques that enable the fabrication of these nanopatterned materials, describes the improved biological effects that have been achieved, and lastly discusses the current limitations of the technology and where future advances may occur. Although this technology is still in its nascency, it will undoubtedly play an important role in the future development of biomaterials and tissue engineering scaffolds for both in vitro and in vivo applications.

AB - Petroleum pollution inevitably occurs at any stage of oil production and exerts a negative impact on the environment. Some microorganisms can degrade petroleum hydrocarbons (PHs). Polluted sludge of Rumaila oil field was use to isolate the highly efficient hydrocarbon-degrading fungal strain. Aspergillus sp. RFC-1 was obtained and its degradation ability for petroleum hydrocarbons was evaluated through surface adsorption, cell uptake, hydrophobicity, surface tension, biosurfactant production, and emulsification activity. In addition, the degradation mechanism was investigated. The results indicated the strain RFC-1 showed high removal activity for PHs, including biodegradation, adsorption, and emulsifiability. On the day 7 of incubation, the removal efficiencies of crude oil, naphthalene (NAP), phenanthrene (PHE), and pyrene (PYR) reached 60.3%, 97.4%, 84.9%, and 90.7%, respectively. Biodegradation efficiencies of crude oil, NAP, PHE, and PYR were 51.8%, 84.6%, 50.3%, and 55.1%, respectively. Surface adsorption and cell absorption by live mycelial pellets followed a decreasing order: PYR >= PHE > NAP > crude oil. Adsorption by heat-killed mycelial pellets increased within 40 and 10 min for crude oil and PAHs, respectively, and remained constant thereafter. Effects of cell surface hydrophobicity, surface tension, and emulsification index were discussed. Intra- and extracellular enzymes of strain RFC-1 played important roles in PHs degradation. The strain RFC-1 is a prospective strain for removing PHs from aqueous environments. PMID- 29577680 TI - Streptococcus dysgalactiae subsp. dysgalactiae isolated from milk of the bovine udder as emerging pathogens: In vitro and in vivo infection of human cells and zebrafish as biological models. AB - Streptococcus dysgalactiae subsp. dysgalactiae (SDSD) is a major cause of bovine mastitis and has been regarded as an animal-restricted pathogen, although rare infections have been described in humans. Previous studies revealed the presence of virulence genes encoded by phages of the human pathogen Group A Streptococcus pyogenes (GAS) in SDSD isolated from the milk of bovine udder with mastitis. The isolates SDSD VSD5 and VSD13 could adhere and internalize human primary keratinocyte cells, suggesting a possible human infection potential of bovine isolates. In this work, the in vitro and in vivo potential of SDSD to internalize/adhere human cells of the respiratory track and zebrafish as biological models was evaluated. Our results showed that, in vitro, bovine SDSD strains could interact and internalize human respiratory cell lines and that this internalization was dependent on an active transport mechanism and that, in vivo, SDSD are able to cause invasive infections producing zebrafish morbidity and mortality. The infectious potential of these isolates showed to be isolate specific and appeared to be independent of the presence or absence of GAS phage encoded virulence genes. Although the infection ability of the bovine SDSD strains was not as strong as the human pathogenic S. pyogenes in the zebrafish model, results suggested that these SDSD isolates are able to interact with human cells and infect zebrafish, a vertebrate infectious model, emerging as pathogens with zoonotic capability. PMID- 29577681 TI - Determination of a radotinib dosage regimen based on dose-response relationships for the treatment of newly diagnosed patients with chronic myeloid leukemia. AB - Radotinib is a second-generation BCR-ABL1 tyrosine kinase inhibitor approved for the treatment of chronic myeloid leukemia in chronic phase (CP-CML). Here, using the data from a Phase 3 study conducted in patients with newly diagnosed CP-CML, the dose-efficacy as well as dose-safety relationship analyses were performed to determine a safe and effective initial dosage regimen of radotinib. A significant positive association was detected between the starting dose of radotinib adjusted for body weight (Dose/BW) and the probability of dose-limiting toxicity (>=grade 3 hematologic and nonhematologic toxicity) (P = 0.003). In contrast, a significant inverse association was discovered between Dose/BW and the probability of major molecular response (BCR-ABL1/ABL1 <= 0.1%) when controlled for sex (P = 0.033). Moreover, frequent dose interruptions and reductions secondary to radotinib toxicities occurred in the Phase 3 study, resulting in nearly half (44%) of patients receiving a reduced dose at a 12-month follow-up. In conclusion, the results of this study demonstrate the need for initial radotinib dose attenuation to improve the long-term efficacy and safety of radotinib. Hence, the authors suggest a new upfront radotinib dose of 400 mg once daily be tested in patients with newly diagnosed CP-CML.

AB - Biofilms are microbial communities composed of bacteria cells and self-produced extracellular polymeric substances and lead to antibiotic resistance, forming a great threat in the fields of medicine, food industries and so on. The formation of biofilms is a multi-stage dynamic process regulated by multiple mechanisms. Recently, researchers paid much more attention to the related research areas of biofilms, especially the detection methods of biofilms. This paper introduced the characteristics and formation process of biofilms as well as the effects of quorum sensing on biofilms development. Meanwhile, we discussed the detection methods of biofilms, especially electrochemical impedance spectroscopy (EIS) in detection of biofilms in detail. Furthermore, we reviewed and predicted that microfluidic chips based EIS served as an in-situ and online monitoring method for biofilms growth.

As research continues, MET is amplified or overexpressed in a wide range of human cancers and closely related with worse prognosis. Therefore, various MET inhibitors are currently being developed as potential treatments for a variety of cancers. Based on our current study we summarize the existing knowledge on structure, biological function and its inhibitors of MET and provide a data phase for future researchers.

Polyamines interact with biological macromolecules through ionic interactions and hydrogen bonds, thereby they could affect the cell growth via regulating the function of macro-molecules. The impact of polyamines on nucleic acids has been thoroughly studied. However, their effects on protein structure and functions are not well established. This review summarizes the recent progress on how polyamines affect proteins, including metabolic enzymes, ion channel proteins and other important proteins. The interaction between polyamines and proteins is discussed, and the review also summarizes the challenges in studying polyamine-protein interaction as well as the potential application of these studies on the therapy of correlated diseases.

This challenge has prompted the development of long-acting recombinant proteins in recent years. Four strategies and methods, including chemical modification, protein engineering, fusion proteins and protein glycosylation are used to modify protein molecule and finally obtain improved pharmacokinetics (PK) properties. This article reviews the four strategies of half-life extension and presents a detailed list of long-acting therapeutics on US, EU and China markets. PMID- 29577687 TI - [METTL3 regulates expression of pluripotent genes in porcine pluripotent stem cells]. AB - In post-transcriptional mRNA modification, m6A has been observed in a wide range of eukaryotes. METTL3, as a component of methyltransferase complex for m6A modification, regulates mouse naive pluripotency and influences mRNA stability, especially affecting the expression level of the key pluripotent transcription factors. To reveal the expression pattern of the porcine METTL3 gene, we analyzed METTL3 expression level in different porcine tissues, somatic cells, and induced pluripotent stem cells (piPSCs) by RT-PCR. To identify the function of METTL3 for regulation of the expression of porcine pluripotent genes, we cloned a 1 859-bp coding sequence of METTL3 and synthesized a shRNA against METTL3. When knocking down METTL3 expression in piPSCs, the cell type of piPSCs became naive-like morphology, alkaline phosphatase activity was increased, and expression level of pluripotent genes NANOG, OCT4 and LIN28A was significantly elevated. In addition, piPSCs cultured in medium containing 10 mmol/L cycloleucine for 48 h exhibited the similar result as that knocked down METTL3. These findings set the stage for optimization of piPS culture condition and further study on the roles of m6A in piPSCs. PMID- 29577688 TI - [Co-expression of beta-glucosidase and Vitreoscilla hemoglobin in Escherichia coli]. AB - In producing recombinant beta-glucosidase in Escherichia coli by high-cell density cultivation (HCDC), insufficient soluble oxygen is always a problem. To address it, Vitreoscilla hemoglobin (VHb) was introduced into Escherichia coli by the bicistron and T7 promoter expression systems, to improve soluble oxygen by bacterial cells and thereby to enhance the biomass and recombinant beta glucosidase production. In the case of bicistron expression system, cell density in shaking flask reached OD600=(4.24+/-0.29), 35.03% higher than that of the control without VHb. Correspondingly, the maximum activity of beta-glucosidase co expressed with VHb was (9.78+/-0.55) U/mL, 25.38% higher than that of the control. In a 3-L fermentor, the maximum activity of beta-glucosidase was 141.23 U/mL, 35.57% higher than that of the control. In contrast, the activity of beta glucosidase co-expressed with VHb under T7 promoter was lower than that of the control, either in flask or in fermentor. Co-expressing beta-glucosidase with VHb using the bicistron expression system may improve the tolerance of E. coli to insufficient soluble oxygen and thus promote the bacterial biomass and the enzyme yield. PMID- 29577689 TI - [Control of acetic acid metabolism of recombinant Yarrowia lipolytica for efficient succinic acid production]. AB - Succinic acid is a high value-added organic acid widely used in food, chemical and pesticide industries. As a new robust non-conventional yeast, Yarrowia lipolytica attracts more and more attention due to its potential for industrial applications. Previously, we obtained a succinic acid-producing strain through gene deletion of succinic acid dehydrogenase subunit encoding gene Ylsdh5, resulting in the strain of PGC01003. However, the recombinant strain produced large amount of acetic acid due to imbalance between glycolysis and TCA cycle which hindered the efficient production of succinic acid. PDH bypass was interfered to decrease the overflow of acetic acid and produce succinic acid under natural pH. Acetic acid was reduced to 4.6 g/L through heterologous expression of acetyl coenzyme A synthase from Salmonella enteric, which was 75.4% of the control strain. Deletion of CoA-transferase gene Ylach1 eliminated acetate formation and improved succinic acid production, and the resulting strain produced as high as 7.0 g/L succinic acid. Our study provides foundation for further construction of efficient cell factory of succinic acid production.

AB - To observe the immunogenicity of hPDGF-B immunogens that were synthesized with the fusional expression vector pET28-Trx and to test the suppressive effect of these specific antibodies induced by both of immunogens on proliferation of human HepG2 hepatoma cells. First, we chose 2 antigenic epitopes hPDGF-BDelta103-118aa and hPDGF-BDelta152-167aa from human PDGF-B and inserted these 2 coding regions into the empty vector plasmid pET28-Trx, separately. Second, mice were immunized with purified recombinant proteins to generate polyclonal antibody. Then we intraperitoneally injected mice bearing hepatoma 22 (H22) tumor cells to prepare antibody ascites. ELISA and Western blot were used to detect the titer and the utility of the antibody, respectively. Finally, HepG2 cells were exposed to PDGF BB protein or anti-PDGF-B ascite antibody in different dilution concentrations groups and the proliferation of HepG2 cells was quantified by CCK8 assay. As the results, we identified mice that could produce high drop of neutralizing antibodies against hPDGF-B induced by both two recombinant proteins. Two anti PDGF-B ascite antibodies could markedly inhibit the proliferation of HepG2 cells by blocking the stimulating effect of PDGF-BB protein. Our results suggest that Trx-PDGF-B recombinant protein as immunogen provides a new method for the preparation of PDGF-B vaccine, and also a new idea for the treatment of hepatocellular carcinoma in clinical practice.

AB - This study aims to develop a new method for the detection of KRAS mutations related to colorectal cancer in cfDNA, and to evaluate the sensitivity and accuracy of the detection. We designed a method of cfDNA based KRAS detection by droplets digital PCR (ddPCR). The theoretical performance of the method is evaluated by reference standard and compared to the ARMS PCR method. Two methods, ddPCR and qPCR, were successfully established to detect KRAS wild type and 7 mutants. Both methods were validated using plasmid standards and actual samples. The results were evaluated by false positive rate, linearity, and limit of detection. Finally, 52 plasma cfDNA samples from patients and 20 samples from healthy people were tested, the clinical sensitivity is 97.64%, clinical specificity is 81.43%. ddPCR method shows higher performance than qPCR. The LOD of ddPCR method reached single digits of cfDNA copies, it can detect as low as 0.01% to 0.04% mutation abundance.

AB - N-glycanase is a class of deglycosylation enzymes, widely used in the study of N glycosylation modification of glycoprotein. In this study, an N-glycanase gene (OsPNGase A, XM_015775832) with high GC content (69.48%) was cloned from rice and then the yeast secretory expression vector pPICZ(alpha)A-OsPNGase A was constructed for the purpose of transformation to Pichia pastoris. After induction in Pichia pastoris SMD1168H, the target protein was purified by DEAE Sepharose and HisTrap HP chromatography, with a yield of 12.3 mg OsPNGase A from 1 L fermentation medium, showing a specific activity of 258 U/mg. SDS-PAGE revealed that the purified OsPNGase A was a single band and showed consistentcy with the expected molecular weight. OsPNGase A could act on transferrin recombinantly expressed in rice, avidin recombinantly expressed in corn and horseradish peroxidase. Furthermore, OsPNGase A showed higher activity than commercial PNGase F towards avidin. OsPNGase A displayed the highest digestion activity at pH 6.0 and 40 degrees C, and was also active in the neutral and alkaline environment. Despite the fact that OsPNGase A was inhibited by reducing agents and surfactants, it still maintained partial enzymatic activity in 100 mmol/L beta-ME or DTT. Therefore, the successful expression of rice OsPNGase A provides a new tool for the study of plant glycoproteins and the establishment of yeast secretion expression system lays the foundation for the preparation of PNGase A.

AB - An HIV-1 cell-cell fusion system was developed to screen HIV-1 entry inhibitors that block cell-cell fusion. In this system, the pEGFP-Tat plasmid was constructed and cotransfected into effector cells (HEK-293T) with HIV-1 envelope plasmid. TZM-bl cell, a genetically engineered cell line that expresses CD4, CXCR4, CCR5 as well as Tat-inducible beta-galactosidase and luciferase reporter gene, was used as target cell. Thus, the co-culture of target cells and effector cells allows the cell fusion via Env and the activity of the fusion inhibitor can be quantified by measuring the reporter protein expression. The experimental parameters were optimized and 11 anti-HIV-1 agents including CCR5 antagonist maraviroc, reverse transcription inhibitor zidovudine (AZT) and integrase inhibitor raltegravir were tested. The result showed that the system exhibited high specificity and sensitivity. Two of eight tested anti-HIV-1 agents were found to block the cell-cell fusion. The system is suitable for efficient screening of HIV-1 cell-cell fusion inhibitors. PMID- 29577694 TI - [Detection of procalcitonin based on fluorescence immune chromatography]. AB - Procalcitonin (PCT) is the precursor of calcitonin related to the severity of human bacterial infection. We made a test strip by coupling anti-PCT to quantum dot, in order to develop a highly sensitive and convenient PCT testing product. The anti-PCT titer had reached 107 because of the stability by coupling anti-PCT with quantum dot. The detecting linear range of the experiment was 0.15 to 120 MUg/L, the sensitivity was 0.007 MUg/L, the recovery range was 91% to 113%, and the intra- and inter-assay coefficient of variation was less than 8%. Comparing the homemade fluorescence-detected test strip with PCT ELISA kit on sale, we got accurate results which could mostly accomplish the test of clinical samples.

AB - With the completion of large-scale genome sequencing of human beings and other organisms, understanding the expression of control elements on the genome has become an important research task in the post-genome era. The enhancer trapping technology is an effective method for identifying enhancer elements in the genome and understanding its mechanism for gene expression regulation. In this study, we selected the stable enhancer trapping line TK4 (head and trunk specific GFP expression), which is generated with the mediation of Tol2 transposon system, and analyzed the trapped enhancers with the techniques of Splinkerette PCR (sp-PCR), in situ hybridization and comparative genomics. We crossed F1 individuals of TK4 line with wild-type zebrafish, collected fertilized eggs, and then detected the expression pattern of green fluorescent protein reporter gene by fluorescence microscopy at six different developmental stages, 6 hpf (hour post fertilization), 24 hpf, 48 hpf, 3 dpf (day post fertilization), 4 dpf and 5 dpf . The zebrafish genome flank sequence near the insertion site of Tol2 transposon was cloned by sp-PCR, and the results revealed that the insertion located at the position 27749253 of chromosome 23, and the transgene inserted reversely inside the intron 1 of rps26 gene. Within the 100 kb region of the insertion site, totally, seven genes including arf3a, wnt10b, wnt1, rps26, IKZF4, dnajc22 and lmbr1l were identified. Comparative genomic analysis by VISTA program revealed that there were two potential enhancer elements in the downstream of rps26 gene, which were conserved non-coding sequence (CNS) 1 and CNS2. The results of in situ hybridization showed that two transcripts of rps26 gene were maternal expression, the expression of rps26-201 in zygote was earlier than that of rps26-001, and the GFP signal of TK4 line zebrafish was not detectable before 6hpf, the expression patterns of rps26 and GFP at the late stages display similarity, and also represent differences, which suggested that the expression of rps26 and GFP may be controlled by the same enhancer, and also by the different enhancer, and two potential enhancers (CNS1 and CNS2) may play a differential regulation roles on the spatial and temporal expression of nearby genes (including rps26). In this study, we successfully obtained two potential enhancers near rps26 gene for the first time, which laid a foundation for further study of the regulation mechanism between these two enhancers and nearby genes in the genome, and the combination technique used in this study also provides a reference for enhancer analysis.

AB - OBJECTIVES: To analyse the relationship between Fourier transform infrared (FTIR) spectrum of rat's spleen tissue and postmortem interval (PMI) for PMI estimation using FTIR spectroscopy combined with data mining method. METHODS: Rats were sacrificed by cervical dislocation, and the cadavers were placed at 20 C. The FTIR spectrum data of rats' spleen tissues were taken and measured at different time points. After pretreatment, the data was analysed by data mining method. RESULTS: The absorption peak intensity of rat's spleen tissue spectrum changed with the PMI, while the absorption peak position was unchanged. The results of principal component analysis (PCA) showed that the cumulative contribution rate of the first three principal components was 96%. There was an obvious clustering tendency for the spectrum sample at each time point. The methods of partial least squares discriminant analysis (PLS-DA) and support vector machine classification (SVMC) effectively divided the spectrum samples with different PMI into four categories (0-24 h, 48-72 h, 96-120 h and 144-168 h). The determination coefficient (R2) of the PMI estimation model established by PLS regression analysis was 0.96, and the root mean square error of calibration (RMSEC) and root mean square error of cross validation (RMSECV) were 9.90 h and 11.39 h respectively. In prediction set, the R2 was 0.97, and the root mean square error of prediction (RMSEP) was 10.49 h. CONCLUSIONS: The FTIR spectrum of the rat's spleen tissue can be effectively analyzed qualitatively and quantitatively by the combination of FTIR spectroscopy and data mining method, and the classification and PLS regression models can be established for PMI estimation.

AB - OBJECTIVES: To investigate FoxO1 expression and its time-dependent changes during the skin incised wound healing. METHODS: After the establishment of the skin incised wound model in mice, the FoxO1 expression of skin in different time periods was detected by immunohistochemistry and Western blotting. RESULTS: Immunohistochemistry staining showed that FoxO1 was weakly expressed in a few fibroblasts of epidermis, hair follicles, sebaceous glands, vessel endothelium and dermis in the control group. The FoxO1 expression was enhanced in the epidermis and skin appendages around the wound during 6-12 h after injury, which could be detected in the infiltrating neutrophils and a small number of monocytes. FoxO1 was mainly expressed in monocytes during 1-3 d after injury, and in neovascular endothelial cells and fibroblasts during 5-10 d. On the 14th day after injury, the FoxO1 expression still could be detected in a few fibroblasts. The Western blotting results showed that the FoxO1 expression quantity of the tissue samples in injury group was higher than in control group. The FoxO1 expression peaked at 12 h and 7 d after injury. CONCLUSIONS: FoxO1 is time dependently expressed in skin wound healing, which can be a useful marker for wound age determination.

AB - OBJECTIVES: To test the changes of the potassium (K+) and magnesium (Mg2+) concentrations in vitreous humor of rabbits along with postmortem interval (PMI) under different temperatures, and explore the feasibility of PMI estimation using mixed-effect model. METHODS: After sacrifice, rabbit carcasses were preserved at 5 C, 15 C, 25 C and 35 C, and 80-100 MUL of vitreous humor was collected by the double-eye alternating micro-sampling method at every 12 h. The concentrations of K+ and Mg2+ in vitreous humor were measured by a biochemical-immune analyser. The mixed-effect model was used to perform analysis and fitting, and established the equations for PMI estimation. The data detected from the samples that were stoned at 10 C, 20 C and 30 C with 20, 40 and 65 h were used to validate the equations of PMI estimation. RESULTS: The concentrations of K+ and Mg2+ [f(x,y)] in vitreous humor of rabbits under different temperature increased along with PMI (x). The relative equations of K+ and Mg2+ concentration with PMI and temperature under 5 C~35 C were fK+(x,y)=3.413 0+0.309 2 x+0.337 6 y+0.010 83 xy-0.002 47 x2 (P<0.000 1), and fMg2+(x,y)=0.745 6+0.006 432 x+0.033 8 y (P<0.000 1), respectively. It was proved that the time of deviation for PMI estimation by K+ and Mg2+ was in 10 h when PMI was between 0 to 40 h, and the time of deviation was in 21 h when PMI was between 40 to 65 h. CONCLUSIONS: the ambient temperature range of 5 C-35 C, the mixed-effect model based on temperature and vitreous humor substance concentrations can provide a new method for the practical application of vitreous humor chemicals for PMI estimation.

AB - OBJECTIVES: To detect the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) to explore its change rule and effects in the repair process of skeletal muscle. METHODS: An injury model of skeletal muscle was established by injection of cardiotoxin into the gastrocnemius muscle of SD male rats. The muscle samples were taken from control group and injury group at each time point (1 h, 4 h, 8 h, 12 h, 16 h, 1 d, 3 d, 5 d, 7 d, 9 d, 13 d, 17 d, 21 d). The morphological changes of skeletal muscle in repair process were observed by HE staining, and the content of reactive oxygen species (ROS) was detected. The expression level of Nrf2 protein was investigated by Western blotting and immunohistochemistry staining. RESULTS: After the skeletal muscle injury, the injury region was infiltrated with inflammatory cells which constituted mainly by lymphocyte neutrophils and mononuclear cells. There were large amounts of immature muscle cells appeared at the 5th day and the muscle repair was completed at the 21th day. Comparing with control group, the ROS content decreased in injury group at the 12th hour (P<0.05), while Nrf2 expression increased at the 16th hour (P<0.05). Moreover, the positive rate of Nrf2 increased after injury, and peaked at 16 h-1 d, then decreased gradually and returned to the level of control group (P<0.05). CONCLUSIONS: The Nrf2 protein involves in the regulation of the repair of skeletal muscle injury. The positive rate of Nrf2 shows a time-dependent expression, which can be used to estimate the wound age of skeletal muscle.

RESULTS: The total vertebral column length showed a good correlation with stature, and the mean values of the frontal and lateral X-ray films of total vertebral column length had the highest correlation coefficients. Three established linear regression equation models were statistically significant (P<0.05), and the equation established with lateral total vertebral column length showed the highest accuracy. CONCLUSIONS: The stature estimation by the measurement of total vertebral column length has high accuracy.

And AlexNet was as a regression model of image recognition. From the total samples above, 60% of male and female DR images of left wrist joint were selected as net train set, and 10% of samples were selected as validation set. As test set, the rest 30% were used to obtain the image recognition accuracy with an error range in +/-1.0 and +/-0.7 age respectively, compared to the real age. RESULTS: The modelling results of deep learning algorithm showed that when the error range was in +/-1.0 and +/-0.7 age respectively, the accuracy of the net train set was 81.4% and 75.6% in male, and 80.5% and 74.8% in female, respectively. When the error range was in +/-1.0 and +/-0.7 age respectively, the accuracy of the test set was 79.5% and 71.2% in male, and 79.4% and 66.2% in female, respectively. CONCLUSIONS: The combination of bone age research on teenagers' left wrist joint and deep learning, which has high accuracy and good feasibility, can be the research basis of bone age automatic assessment system for the rest joints of body.

AB - OBJECTIVES: To explore the application of activities of daily living (ADL) scale in mild psychiatric impairment assessment under the guideline of Classification of Human Body Disability Caused by Injury. METHODS: A total of 124 subjects with organic mental disorders and mild psychiatric impairments (levels 7 to 10), and 106 healthy controls were included in. All participants were assessed by the ADL scale, physical self-maintenance scale (PSMS) and instrumental activities of daily living (IADL) scale. The difference between the scores of control group and study group, and the relationship of impairment level and the scores were compared, and the threshold value was determined according to the ROC curve. RESULTS: The total scores of ADL, IADL and PSMS were significantly different between the control group and the study group (P<0.05). The scores of ADL, IADL, PSMS were significantly different among the impairment levels (P<0.05), which showed a relativity with impairment level. The scores of ADL corresponding to levels 10, 9, 8 and 7 were 14-17, 18-23, 24-29 and 30-34, respectively, which showed a good correlation between the conclusion according to the scale and the expert's opinion (kappa= 0.914, P<0.05). CONCLUSIONS: The score of ADL was significantly related to mild psychiatric impairment, and the higher ADL score represents the more severe disability, which can be used as a reference index for preliminarily judging the level of mild psychiatric impairment. PMID- 29577705 TI - [Research Progress of Vitreous Humor Detection Technique on Estimation of Postmortem Interval]. AB - Estimation of postmortem interval (PMI) plays a crucial role in forensic study and identification work. Because of the unique anatomy location, vitreous humor is considered to be used for estima- ting PMI, which has aroused interest among scholars, and some researches have been carried out. The detection techniques of vitreous humor are constantly developed and improved which have been gradually applied in forensic science, meanwhile, the study of PMI estimation using vitreous humor is updated rapidly. This paper reviews various techniques and instruments applied to vitreous humor detection, such as ion selective electrode, capillary ion analysis, spectroscopy, chromatography, nano-sensing technology, automatic biochemical analyser, flow cytometer, etc., as well as the related research progress on PMI estimation in recent years. In order to provide a research direction for scholars and promote a more accurate and efficient application in PMI estimation by vitreous humor analysis, some inner problems are also analysed in this paper. PMID- 29577706 TI - [Research Progress on Determination of Drowning Site]. AB - The bodies found in water are one of the most common types in forensic practice. The discovery site of the body is often not the drowning site. However, the determination of drowning site is vital for the identification of victim. Inorganic particles and planktons, such as granular impurities, diatoms and bacteria, are valuable markers for the diagnosis of drowning. By comparing the granular impurities and planktons in tissues and suspicious drowning mediums, the drowning site can be concluded based on their similarity of types and distribution, which has practical applied value. In this paper, the research progress on determination of drowning site is summarized to provide reference for the peers.

AB - Coronary artery spasm (CAS) is a hyper-contraction of segmental coronary artery in response to multiple stimuli. At present, it's still in lack of specific diagnostic indicators of sudden cardiac death caused by CAS. This review summarizes current researches on the mechanisms of CAS and describes the roles of vascular endothelial dysfunction and vascular smooth muscle hypersensitivity in the course of CAS. Furthermore, the molecular mechanisms of the endogenous NO and endothelin-1 cause vascular endothelial dysfunction, and the phosphorylation of MLC2, Rho kinase and endoplasmic reticulum stress related to vascular smooth muscle hypersensitivity are discussed. Meanwhile, the possibility of forensic application for the related molecules on the diagnosis of sudden cardiac death caused by CAS are also explored. PMID- 29577708 TI - [Research Progress of the Effects of Monocular Visual Impairment on Binocular Vision]. AB - Binocular vision refers to a progress of analysing and integrating the binocular visual signals into a whole and three-dimensional sensory perception by higher nerve centre. In this process, the interac- tion between the two eyes results in the changes of output signal, which is called binocular interaction. Through a series of subjective and objective experiments, it can be concluded that binocular interaction can be divided into three types: facilitation, summation and suppression, and the forms of binocular interaction in different visual states are different. In general, the visual signal is processed by binocular interaction, so that there are some differences between binocular vision and monocular vision. The extent of the difference can be affected by the damage of monocular vision and then affects the binocular vision. Thus, it is necessary for forensic scientists to further study the effects of the monocular visual impairment on visual function. Based on relevant data, this paper reviews the mechanism of the monocular visual impairment in binocular vision, the research methods and the application prospect in forensic science.

AB - Circular RNA (circRNA) is a type of noncoding RNA with tissue specificity and high stability, which forms a closed continuous loop and is abundantly expressed in tissue cells. According to recent research, the regulatory function of circRNA elucidating in the occurrence and development of disease shows a potential for diagnosing clinical disease and revealing disease mechanism.

PMID- 29577710 TI - Etiological periodontal treatment with and without low-level laser therapy on IL 1beta level in gingival crevicular fluid: an in vivo multicentric pilot study. AB - Cytokine proteins may have important roles during different human physiological and pathological processes. In the oral cavity, the bone loss and periodontal tissue pathology was related to inflammatory process activation. The aim of the present study was to assess the effects of etiological periodontal therapy with and without the use of Low Level Laser Therapy (LLLT) on clinical periodontal parameters and interleukin (IL)-1beta level in gingival crevicular fluid (GCF) from chronic periodontitis (CP) patients. Thirty non-smoker CP patients were selected from the Foggia University Dental Clinic and other 2 private dental clinics. All patients were divided into two homogeneous randomized groups: 15 patients were treated with only scaling and root planing (group 1) and 15 patients with scaling and root planing etiological treatment and LLLT (group 2). In all sites, at baseline before treatment, the periodontal pocket depth (PPD) and bleeding on probing (BOP) were measured. In the PPD sites, the GCF samples were collected from 30 deep (>=5 mm) and shallow (<=3 mm) sites and IL-1beta were evaluated at baseline, after 10 days and 1 month. In all the samples at baseline, the IL-1beta concentration in GCF and BOP rate were significantly higher at deep PPD sites than at the shallow ones. After 10 days in all samples no PPD improvement was observed in the BOP rate but the IL-1 beta level was statistically significantly improved (p<0.005) in group 2 compared to group 1. At 10 days and 1 month, in all deep PPD sites, PPD and BOP improvements were observed. At same time, IL-1beta levels were lower and statistically significantly (p<0.005) improved in group 2 compared to group 1. The results confirmed that the periodontal etiology treatment of deep PPD sites with or with out associated LLLT promotes periodontal health. Etiological treatment associated with LLLT, improves BOP and inflammation in periodontal disease. Moreover, the IL 1beta concentration changes in GCF suggest these cytokines as a predictable marker of gingival inflammation in chronic periodontitis patients. PMID- 29577711 TI - IL-1 haplotype analysis in periodontal disease. AB - Numerous studies have established statistical associations of the IL-1 gene cluster polymorphisms with various inflammatory diseases. Deriving from that, the present study was intended to determine whether single-nucleotide polymorphisms (SNPs) in these gene are also associated with periodontal disease in a Linkage disequilibrium analysis. This investigation also created two haplotype blocks, both consisting of two different SNPs. Recent theoretical analyses indicate that research with an interpretation of periodontal disease as a complex, oligogenic disorder, with IL-1 genetic variation contributes an important but not exclusive influence on disease risk. Further studies are needed to confirm these results and to understand the mechanisms behind the observed association between IL-1 SNPs and periodontal disease. PMID- 29577714 TI - Effects of Melanin on Optical Behavior of Polymer: From Natural Pigment to Materials Applications. AB - Melanin is a kind of ubiquitous natural pigment, which serves a variety of protective functions in many organisms. In the present study, natural melanin and synthetic melanin nanoparticles (NPs) were systematically investigated for its potential application in polymeric optical materials. A significant short wavelength shielding and high visible light transparency polymer nanocomposite was easily obtained via tuning the melanin particle size. In particular, the nanocomposite film with melanin NPs (diameter ~ 15 nm) loading even as low as 1 wt % blocks most ultraviolet light below 340 nm and still keeps high visible light transparency (83%) in the visible spectrum. More importantly, because of the excellent photoprotection and radical scavenging capabilities of melanin, the resulting polymer nanocomposite exhibits outstanding photostability. In effect, such fantastic melanin NPs is promising for applications in various optical materials. PMID- 29577715 TI - The Nonbilayer Lipid MGDG and the Major Light-Harvesting Complex (LHCII) Promote Membrane Stacking in Supported Lipid Bilayers. AB - The thylakoid membrane of algae and land plants is characterized by its intricate architecture, comprising tightly appressed membrane stacks termed grana. The contributions of individual components to grana stack formation are not yet fully elucidated. As an in vitro model, we use supported lipid bilayers made of thylakoid lipid mixtures to study the effect of major light-harvesting complex (LHCII), different lipids, and ions on membrane stacking, seen as elevated structures forming on top of the planar membrane surface in the presence of LHCII protein. These structures were examined by confocal laser scanning microscopy, atomic force microscopy, and fluorescence recovery after photobleaching, revealing multilamellar LHCII-membrane stacks composed of connected lipid bilayers. Both native-like and non-native interactions between the LHCII complexes may contribute to membrane appression in the supported bilayers. However, applying in vivo-like salt conditions to uncharged glycolipid membranes drastically increased the level of stack formation due to enforced LHCII-LHCII interactions, which is in line with recent crystallographic and cryo-electron microscopic data [Wan, T., et al. (2014) Mol. Plant 7, 916-919; Albanese, P., et al. (2017) Sci. Rep. 7, 10067-10083]. Furthermore, we observed the nonbilayer lipid MGDG to strongly promote membrane stacking, pointing to the long-term proposed function of MGDG in stabilizing the inner membrane leaflet of highly curved margins in the periphery of each grana disc because of its negative intrinsic curvature [Murphy, D. J. (1982) FEBS Lett. 150, 19-26]. PMID- 29577716 TI - Facile Synthesis of Ultrafine Hematite Nanowire Arrays in Mixed Water-Ethanol Acetic Acid Solution for Enhanced Charge Transport and Separation. AB - Nanostructure engineering is of great significance for semiconductor electrode to achieve high photoelectrochemical performance. Herein, we report a novel strategy to fabricate ultrafine hematite (alpha-Fe2O3) nanowire arrays in a mixed water ethanol-acetic acid (WEA) solvent. To the best of our knowledge, this is the first report on direct growth of ultrafine (~10 nm) alpha-Fe2O3 nanowire arrays on fluorine-doped tin oxide substrates through solution-based fabrication process. The effect of WEA ratio on the morphology of nanowires has been systematically studied to understand the formation mechanism. Photoelectrochemical measurements were conducted on both Ti-treated alpha-Fe2O3 nanowire and nanorod photoelectrodes. It reveals that alpha-Fe2O3 nanowire electrode has higher photocurrent and charge separation efficiencies than nanorod electrode if the carrier concentration and space-charge carrier width are in the same order of magnitude. Normalized by electrochemically active surface area, the Ti-treated alpha-Fe2O3 nanowire electrode obtains 6.4 times higher specific photocurrent density than nanorod electrode. This superiority of nanowires arises from the higher bulk and surface charge separation efficiencies, which could be partly attributed to reduced distance that holes must transfer to reach the semiconductor-liquid junction. PMID- 29577717 TI - Identification of Individual Immobilized DNA Molecules by Their Hybridization Kinetics Using Single-Molecule Fluorescence Imaging. AB - Single-molecule fluorescence methods can count molecules without calibration, measure kinetics at equilibrium, and observe rare events that cannot be detected in an ensemble measurement. We employ total internal reflection fluorescence microscopy to monitor hybridization kinetics between individual spatially resolved target DNA molecules immobilized at a glass interface and fluorescently labeled complementary probe DNA in free solution. Using super-resolution imaging, immobilized target DNA molecules are located with 36 nm precision, and their individual duplex formation and dissociation kinetics with labeled DNA probe strands are measured at site densities much greater than the diffraction limit. The purpose of this study is to evaluate uncertainties in identifying these individual target molecules based on their duplex dissociation kinetics, which can be used to distinguish target molecule sequences randomly immobilized in mixed-target samples. Hybridization kinetics of individual target molecules are determined from maximum likelihood estimation of their dissociation times determined from a sample of hybridization events at each target molecule. The dissociation time distributions thus estimated are sufficiently narrow to allow kinetic discrimination of different target sequences. For example, a single-base thymine-to-guanine substitution on immobilized strands produces a 2.5-fold difference in dissociation rates of complementary probes, allowing for the identification of individual target DNA molecules by their dissociation rates with 95% accuracy. This methodology represents a step toward high-density single molecule DNA microarray sensors and a powerful tool to investigate the kinetics of hybridization at surfaces at the molecular level, providing information that cannot be acquired in ensemble measurements. PMID- 29577719 TI - Anisamide-Anchored Lyotropic Nano-Liquid Crystalline Particles with AIE Effect: A Smart Optical Beacon for Tumor Imaging and Therapy. AB - The prospective design of nanocarriers for personalized oncotherapy should be an ensemble of targeting, imaging, and noninvasive therapeutic capabilities. Herein, we report the development of the inverse hexagonal nano-liquid crystalline (NLC) particles that are able to host formononetin (FMN), a phytoestrogen with known anticancer activity, and tetraphenylethene (TPE), an iconic optical beacon with aggregation-induced emission (AIE) signature, simultaneously. Ordered three dimensional mesoporous internal structure and high-lipid-volume fraction of NLC nanoparticles (NLC NPs) frame the outer compartment for the better settlement of payloads. Embellishment of these nanoparticles by anisamide (AA), a novel sigma receptor targeting ligand using carbodiimide coupling chemistry ensured NLC's as an outstanding vehicle for possible utility in surveillance of tumor location as well as the FMN delivery through active AIE imaging. The size and structural integrity of nanoparticles were evaluated by quasi-elastic light scattering, cryo field emission scanning electron microscopy small-angle X-ray scattering. The existence of AIE effect in the nanoparticles was evidenced through the photophysical studies that advocate the application of NLC NPs in fluorescence based bioimaging. Moreover, confocal microscopy illustrated the single living cell imaging ability endowed by the NLC NPs. In vitro and in vivo studies supported the enhanced efficacy of targeted nanoparticles (AA-NLC-TF) in comparison to nontargeted nanoparticles (NLC-TF) and free drug. Apparently, this critically designed multimodal NLC NPs may establish a promising platform for targeted and image-guided chemotherapy for breast cancer.

PMID- 29577720 TI - Rational Design of Au@Pt Multibranched Nanostructures as Bifunctional Nanozymes. AB - One of the current challenges in nanozyme-based nanotechnology is the utilization of multifunctionalities in one material. In this regard, Au@Pt nanoparticles (NPs) with excellent enzyme-mimicking activities due to the Pt shell and unique surface plasmon resonance features from the Au core have attracted enormous research interest. However, the unique surface plasmon resonance features from the Au core have not been widely utilized. The practical problem of the optical damping nature of Pt hinders the research into the combination of Au@Pt NPs' enzyme-mimicking properties with their surface-enhanced Raman scattering (SERS) activities. Herein, we rationally tuned the Pt amount to achieve Au@Pt NPs with simultaneous plasmonic and enzyme-mimicking activities. The results showed that Au@Pt NPs with 2.5% Pt produced the highest Raman signal in 2 min, which benefited from the remarkably accelerated catalytic oxidation of 3,3',5,5' tetramethylbenzidine with the decorated Pt and strong electric field retained from the Au core for SERS. This study not only demonstrates the great promise of combining bimetallic nanomaterials' multiple functionalities but also provides rational guidelines to design high-performance nanozymes for potential biomedical applications. PMID- 29577721 TI - Portfolio Optimization of Nanomaterial Use in Clean Energy Technologies. AB - While engineered nanomaterials (ENMs) are increasingly incorporated in diverse applications, risks of ENM adoption remain difficult to predict and mitigate proactively. Current decision-making tools do not adequately account for ENM uncertainties including varying functional forms, unique environmental behavior, economic costs, unknown supply and demand, and upstream emissions. The complexity of the ENM system necessitates a novel approach: in this study, the adaptation of an investment portfolio optimization model is demonstrated for optimization of ENM use in renewable energy technologies. Where a traditional investment portfolio optimization model maximizes return on investment through optimal selection of stock, ENM portfolio optimization maximizes the performance of energy technology systems by optimizing selective use of ENMs. Cumulative impacts of multiple ENM material portfolios are evaluated in two case studies: organic photovoltaic cells (OPVs) for renewable energy and lithium-ion batteries (LIBs) for electric vehicles. Results indicate ENM adoption is dependent on overall performance and variance of the material, resource use, environmental impact, and economic trade-offs. From a sustainability perspective, improved clean energy applications can help extend product lifespans, reduce fossil energy consumption, and substitute ENMs for scarce incumbent materials.

AB - The origin of enantioselectivity in the asymmetric alkynylation of trihalomethyl ketones catalyzed by octahedral stereogenic-at-ruthenium complexes has been investigated through density functional theory calculations. Computational results support a mechanism involving formation of a ruthenium acetylide, followed by pre-coordination of the trihalomethyl ketone through the carbonyl oxygen and intramolecular attack of the acetylide via a compact four-membered transition state. Differences in computed free energies of activation for the formation of the major and minor propargyl alcohol enantiomers are in good agreement with the experimentally observed levels of asymmetric induction. Analysis of fragment distortion energies shows that disfavored transition states are destabilized due to the more severe distortion and loss of pi-conjugation in the coordinated arylketone fragments. Examination of the different substitution patterns in the ketone substrate and the catalyst reveals the key steric factors that control the enantioselectivity. Finally, calculations indicate promising directions for the simplification of the catalyst scaffold while preserving the high levels of enantioselectivity of these alkynylation reactions.

AB - The search for ultrathin magnetic films with large perpendicular magnetocrystalline anisotropy (PMA) has been inspired for years by the continuous miniaturization of magnetic units in spintronics devices. The common magnetic materials used in research and applications are based on Fe because the pure Fe metal is the best yet simple magnetic material from nature. Through systematic first-principles calculations, we explored the possibility to produce large PMA with ultrathin Fe on non-noble and non-magnetic Pb(001) substrate. Interestingly, huge magnetocrystalline anisotropy energy (MAE) of 7.6 meV was found in the Pb/Fe/Pb(001) sandwich structure with only half monolayer Fe. The analysis of electronic structures reveals that the magnetic proximity effect at the interface is responsible for this significant enhancement of MAE. The MAE further increases to 13.6 meV with triply repeated capping Pb and intermediate Fe layers. Furthermore, the MAE can be tuned conveniently by charge injection.

AB - Quantitation and in situ monitoring of target mRNA (mRNA) in living cells remains a significant challenge for the chemical and biomedical communities. To quantitatively detect mRNA expression levels in living cells, we have developed DNA-driven gold nanorod coated platinum-upconversion nanoparticle satellite assemblies (termed Au NR@Pt-UCNP satellites) for intracellular thymidine kinase 1 (TK1) mRNA analysis. The nanostructures were capable of recognizing target mRNA in a sequence-specific manner as luminescence of UCNPs was effectively quenched by Au NR@Pt within the assemblies. Following recognition, UCNPs detached from Au NR@Pt, resulting in luminescence restoration to achieve effective in situ imaging and quantifiable detection of target mRNA. The upconversional luminescence intensity of confocal images showed a good linear relationship with intracellular TK1 mRNA ranging from 1.17 to 65.21 fmol/10 MUg RNA and a limit of detection (LOD) of 0.67 fmol/10 MUg RNA. We believe that our present assay can be broadly applied for detection of endogenous biomolecules at the cellular and tissue levels and restoration of tissue homeostasis in vivo. PMID- 29577725 TI - Origins of the Mechanochemical Coupling of Peptide Bond Formation to Protein Synthesis. AB - Mechanical forces acting on the ribosome can alter the speed of protein synthesis, indicating that mechanochemistry can contribute to translation control of gene expression. The naturally occurring sources of these mechanical forces, the mechanism by which they are transmitted 10 nm to the ribosome's catalytic core, and how they influence peptide bond formation rates are largely unknown. Here, we identify a new source of mechanical force acting on the ribosome by using in situ experimental measurements of changes in nascent-chain extension in the exit tunnel in conjunction with all-atom and coarse-grained computer simulations. We demonstrate that when the number of residues composing a nascent chain increases, its unstructured segments outside the ribosome exit tunnel generate piconewtons of force that are fully transmitted to the ribosome's P site. The route of force transmission is shown to be through the nascent polypetide's backbone, not through the wall of the ribosome's exit tunnel. Utilizing quantum mechanical calculations we find that a consequence of such a pulling force is to decrease the transition state free energy barrier to peptide bond formation, indicating that the elongation of a nascent chain can accelerate translation. Since nascent protein segments can start out as largely unfolded structural ensembles, these results suggest a pulling force is present during protein synthesis that can modulate translation speed. The mechanism of force transmission we have identified and its consequences for peptide bond formation should be relevant regardless of the source of the pulling force.

AB - In this manuscript, we report the first synthesis of an organic monomolecular emitter, which behaves as a circularly polarized luminescence (CPL)-based ratiometric probe. The enantiopure helical ortho-oligo(phenylene)ethynylene ( o OPE) core has been prepared by a new and efficient macrocyclization reaction. The combination of such o-OPE helical skeleton and a pyrene couple leads to two different CPL emission features in a single structure whose ratio linearly responds to silver(I) concentration.

AB - Organometallic perovskite (OMP) CH3NH3PbI3 doped with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) has been shown to form bulk heterojunction (OMP-PCBM BHJ) for improved charge separation. In this work, the OMP-PCBM BHJ photosensitizer is combined with graphene field effect transistors (GFETs) with a ferroelectric Pb0.92La0.08Zr0.52Ti0.48O3 gate of high gating efficiency. A remarkable gate tunability via shifting the Fermi energy of graphene with respect to the valence band maximum and conduction band minimum of the OMP was observed, which is critical for facilitating efficient charge transfer across the OMP-PCBM BHJ/GFET interface. The combination of the high-efficiency charge separation by BHJ and charge transfer by high gate tunability leads to achievement of high photoresponsivity up to 7 * 106 A/W and detectivity exceeding 7 * 1012 Jones at 550 nm at a small gate voltage of 1.0 V. These results represent almost 2 orders of magnitude improvement over that without a gate tuning under the similar experimental condition, illustrating the importance of the interface electronic structure in optimizing the optoelectronic performance of the OMP-PCBM BHJ/GFET devices. PMID- 29577729 TI - Toward Semistructural Cellulose Nanocomposites: The Need for Scalable Processing and Interface Tailoring. AB - Cellulose nanocomposites can be considered for semistructural load-bearing applications where modulus and strength requirements exceed 10 GPa and 100 MPa, respectively. Such properties are higher than for most neat polymers but typical for molded short glass fiber composites. The research challenge for polymer matrix biocomposites is to develop processing concepts that allow high cellulose nanofibril (CNF) content, nanostructural control in the form of well-dispersed CNF, the use of suitable polymer matrices, as well as molecular scale interface tailoring to address moisture effects. From a practical point of view, the processing concept needs to be scalable so that large-scale industrial processing is feasible. The vast majority of cellulose nanocomposite studies elaborate on materials with low nanocellulose content. An important reason is the challenge to prevent CNF agglomeration at high CNF content. Research activities are therefore needed on concepts with the potential for rapid processing with controlled nanostructure, including well-dispersed fibrils at high CNF content so that favorable properties are obtained. This perspective discusses processing strategies, agglomeration problems, opportunities, and effects from interface tailoring. Specifically, preformed CNF mats can be used to design nanostructured biocomposites with high CNF content. Because very few composite materials combine functional and structural properties, CNF materials are an exception in this sense. The suggested processing concept could include functional components (inorganic clays, carbon nanotubes, magnetic nanoparticles, among others). In functional three-phase systems, CNF networks are combined with functional components (nanoparticles or fibril coatings) together with a ductile polymer matrix. Such materials can have functional properties (optical, magnetic, electric, etc.) in combination with mechanical performance, and the comparably low cost of nanocellulose may facilitate the use of large nanocomposite structures in industrial applications. PMID- 29577730 TI - An Unprecedented (Semi)Favorskii Rearrangement. Evidence for the 2 (Acyloxy)cyclopropanones. AB - Discovery and development of an unprecedented (semi)Favorskii rearrangement has been reported. The intermediacy of structurally singular (acyloxy)cyclopropanones has been unraveled by fruitful control experiments including a crossover experiment. This class of cyclopropanones is found to be inert for classical Favorskii functionalization and preferably undergoes a decycloisomerization (ring chain valence tautomerism) to alpha-(acyloxy)enones. A cascade conversion of alpha,alpha-diiodo-alpha'-acetoxyketones to (acyloxy)cyclopropanones via alpha iodo-alpha'-acetoxyketones has been achieved by the synchronous dual basicity (Lewis and Bronsted) of amines. The overall process is found to be very general for diverse substrates and highly efficient. PMID- 29577731 TI - Individually Dispersed Gold Nanoshell-Bearing Cellulose Nanocrystals with Tailorable Plasmon Resonance. AB - Cellulose nanocrystals (CNCs) can be attractive templates for the generation of functional inorganic/organic nanoparticles, given their fine sizes, aspect ratios, and sustainable worldwide availability in abundant quantities. Here, we present for the first time a scalable, surfactant-free, tailorable wet chemical process for converting commercially available CNCs into individual aspected gold nanoshell-bearing particles with tunable surface plasmon resonance bands. Using a rational cellulose functionalization approach, stable suspensions of positively charged CNCs have been generated. Continuous, conductive, nanocrystalline gold coatings were then applied to the individual, electrostatically stabilized CNCs via decoration with 1-3 nm diameter gold particles followed by electroless gold deposition. Optical analyses indicated that these core-shell nanoparticles exhibited two surface plasmon absorbance bands, with one located in the visible range (near 550 nm) and the other at near infrared (NIR) wavelengths. The NIR band possessed a peak maximum wavelength that could be tuned over a wide range (1000-1300 nm) by adjusting the gold coating thickness. The bandwidth and wavelength of the peak maximum of the NIR band were also sensitive to the particle size distribution and could be further refined by fractionation using viscosity gradient centrifugation.

AB - The current study sought to investigate the factor structure of the California Verbal Learning Test-Second Edition (CVLT-II) Short Form in a trauma-exposed sample. We used confirmatory factor analysis to test four competing models proposed by Donders in a study investigating the CVLT-II Standard Form. Consistent with Donders, a four-factor model consisting of Attention Span, Learning Efficiency, Delayed Memory, and Inaccurate Memory was supported. These results confirm the latent structure of the CVLT-II holds for the CVLT-II in its Short Form as well as in a trauma-exposed sample. Findings are particularly important, given previous research indicating attention span and learning efficiency may underpin memory complaints in trauma-exposed individuals. PMID- 29577733 TI - Engaging Axiology: Enabling Meaningful Transdisciplinary Collaboration in Adapted Physical Activity. AB - In this article, I explore the concept of axiology in the context of adapted physical activity research and analyze its connection to the more commonly discussed paradigmatic assumptions of epistemology and ontology. Following methodological scholars, I argue for an acknowledgment of the pivotal role that axiology already plays in adapted physical activity research and for the potential interdisciplinary and transdisciplinary opportunities that could be enabled by engaging with axiology in more explicit ways. I discuss a number of potential axiological gaps between the field of adapted physical activity and disability communities, arguing that such differences may undermine attempts at doing meaningful transdisciplinary research with such communities. I offer strategies for bridging these axiological gaps, encouraging us to work together in axiologically reflexive ways in order to increase meaningful opportunities for more people with disabilities to be engaged in the movement-based activities and communities of their choice. PMID- 29577734 TI - Do clinicians assess patients' religiousness? An audit of an aged psychiatry community team. AB - OBJECTIVES: To determine the frequency and quality of religious history taking of patients by clinicians working in an old age psychiatry service. METHODS: A retrospective audit of 80 randomised patient files from the Koropiko Mental Health Services for Older People (MHSOP) in Middlemore Hospital, Auckland, New Zealand. RESULTS: A total of 66 clinical records were available for analysis. A religious history was taken in 33/66 (50%) patients. However, when such histories were evaluated using the FICA assessment tool, only 10/33 (30.3%) histories contained detailed information regarding the patient's religiousness. CONCLUSIONS: The infrequency and low quality of religious histories discovered in this audit suggest that clinicians need more training in taking a religious history from patients.

AB - As health care systems move toward value-based care, training future leaders in quality improvement (QI) is essential. Web-based training allows for broad dissemination of QI knowledge to geographically distributed learners. The authors conducted a longitudinal evaluation of a structured, synchronous web-based, advanced QI curriculum that facilitated engagement and real-time feedback. Learners (n = 54) were satisfied (overall satisfaction; M = 3.31/4.00), and there were improvements in cognitive (immediate QI knowledge tests; P = .02), affective (self-efficacy of QI skills; P < .001), and skill-based learning (Quality Improvement Knowledge Application Tool; P < .001). There was significant improvement in affective transfer (interprofessional attitudes on the job; p < .01) but no significant change on cognitive (distal QI knowledge test; P = .91), or skill-based transfer (self-reported interprofessional collaboration job skills; P = .23). The findings suggest that this model can be effective to train geographically distributed future QI leaders.

AB - Posttraumatic growth theory posits that when life circumstances are perceived as stressful, secondary appraisal processes can be recruited in ways to facilitate both coping efforts and personal growth. Using a mixed-methods approach, we found mothers' most challenging experiences involved child behavior (e.g. aggression, communication, and social issues) and psychosocial impacts (e.g. lack of social support, perceived judgment of others, perceived loss, and personal distress). Descriptions of most rewarding experiences reflect posttraumatic growth frameworks including constructive perceptions about themselves, life, and their relationships as well as evidence for what Maercker and Zoellner call illusory types of posttraumatic growth. Quantitative data were subjected to a hierarchical regression analysis for self-reported posttraumatic growth and included mothers' demographics, child functioning, and psychosocial measures. As predicted, posttraumatic growth was positively associated with social support from mothers' most important network member and quiet ego characteristics, a type of eudaimonic motivation. Contrary to expectation, neither autism spectrum disorder-related rumination nor time since diagnosis (or their interaction) was associated with posttraumatic growth. Discussion focuses on the practical implications of our findings that posttraumatic growth-related coping includes both constructive and illusory forms and the importance of social support and eudaimonic motivation in facilitating positive forms of secondary coping.

PMID- 29577740 TI - Biological, Psychological, and Social Predictors of Longevity Among Utah Centenarians. AB - Studies of longevity among centenarians examine biological, psychological, and social factors, yet few consider these components concurrently. This study explores such factors individually and collectively, as they are related to days lived past the age of 100 years. Data from 268 family members of centenarians identified in the State of Utah between 2008 and 2015 were used in negative binomial models predicting number of days lived among the centenarians. Findings suggested that sleep latency (biological), life satisfaction (psychological), and attachment closeness (social) were predictive factors of more days lived within individual models. When considered together, sleep latency and life satisfaction remained significant predictors of days lived. Although biological factors are commonly considered in relation to longevity, this study further indicates that psychological and social factors may play important roles in life expectancy. Further examination is needed to explore how these factors link additionally to active life expectancy.

How possible is it to live our lives without categories when life is necessarily categorical? In this brief provocation, I want to explore the disability labels through recourse to three perspectives that have much to say about categorization, disability, and the human condition: the biopsychological, the biopolitical, and, what I term, an in-between-all politics. It is my view that disability categories intervene in the world in some complex and often contradictory ways. One way of living with contradictions is to work across disciplinary boundaries, thus situating ourselves across divides and embracing uncertainty and contradiction to enhance all our lives. I will conclude with some interdisciplinary thoughts for the field of adapted physical activity. PMID- 29577741 TI - LIBERTI: A SMART study in plastic surgery. AB - BACKGROUND/AIMS: Laser treatment of burns scars is considered by some providers to be standard of care. However, there is little evidence-based research as to the true benefit. A number of factors hinder evaluation of the benefit of laser treatment. These include significant heterogeneity in patient response and possible delayed effects from the laser treatment. Moreover, laser treatments are often provided sequentially using different types of equipment and settings, so there are effectively a large number of overall treatment options that need to be compared. We propose a trial capable of coping with these issues and that also attempts to take advantage of the heterogeneous response in order to estimate optimal treatment plans personalized to each individual patient. It will be the first large-scale randomized trial to compare the effectiveness of laser treatments for burns scars and, to our knowledge, the very first example of the utility of a Sequential Multiple Assignment Randomized Trial in plastic surgery. METHODS: We propose using a Sequential Multiple Assignment Randomized Trial design to investigate the effect of various permutations of laser treatment on hypertrophic burn scars. We will compare and test hypotheses regarding laser treatment effects at a general population level. Simultaneously, we hope to use the data generated to discover possible beneficial personalized treatment plans, tailored to individual patient characteristics. RESULTS: We show that the proposed trial has good power to detect laser treatment effect at the overall population level, despite comparing a large number of treatment combinations. The trial will simultaneously provide high-quality data appropriate for estimating precision-medicine treatment rules. We detail population-level comparisons of interest and corresponding sample size calculations. We provide simulations to suggest the power of the trial to detect laser effect and also the possible benefits of personalization of laser treatment to individual characteristics. CONCLUSION: We propose, to our knowledge, the first use of a Sequential Multiple Assignment Randomized Trial in surgery. The trial is rigorously designed so that it is reasonably straightforward to implement and powered to answer general overall questions of interest. The trial is also designed to provide data that are suitable for the estimation of beneficial precision-medicine treatment rules that depend both on individual patient characteristics and on-going real-time patient response to treatment. PMID- 29577743 TI - Challenges, Opportunities, and Methods for Large-Scale Evaluations. AB - The logic, theory, and practice of large-scale evaluation were once limited to large federal initiatives. However, with the advent of regularly collected performance measures and the often multisite implementation of quality improvement efforts, there is an opportunity to adopt large-scale evaluation methods in local and regional evaluation efforts. While ineffective programs show little variation in their ineffectiveness, effective programs generally show a range of effects. A central task of large-scale evaluation is to describe and ascribe why the same program, implemented in multiple settings, produces different effects. By its attention to variation attributable to setting, activities, outputs, and by participants and documenting the conditions in which programs achieve greater and lesser success, large-scale evaluation supports the needs of decision-makers when choosing to implement an evidence-based program. In addition to knowing a program is effective, decision-makers want to know whether it is appropriate for their situation and what facilitates or impedes effective implementation and bears on the program's ultimate effectiveness. This article presents the different methods and approaches appropriate for effectively and efficiently constructing and executing a large-scale evaluation that will provide decision-makers the evidence they need for evidence-informed adoption of effective programs.

AB - Endophytic fungi were isolated from red alga Asparagopsis taxiformis - Falkenbergia stage, collected from the Brazilian coast, and were identified as Annulohypoxylon stygium (AT-03) and A. yungensis (AT-06) based on their macro/micromorphological and molecular features. Bioassay-guided fractionation of the EtOAc extract from laboratory cultures of both strains yielded known compounds pyrogallol from A. stygium, (3R)-scytalone and (3R,4R)-4-hydroxy scytalone from A. yungensis. Pyrogallol was active against methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli strains. An inactive fraction from A. stygium afforded two additional compounds, (3R,4R)-3,4,5-trihydroxy-1 tetralone and tyrosol. Optically active compounds had their stereochemistry determined by circular dichroism (CD) spectroscopy.

AB - OBJECTIVE: The objective of this article was to conduct a cost analysis comparing the costs of a supportive housing intervention to inpatient care for clients with severe mental illness who were designated alternative-level care while inpatient at the Centre for Addiction and Mental Health in Toronto. The intervention, called the High Support Housing Initiative, was implemented in 2013 through a collaboration between 15 agencies in the Toronto area. METHOD: The perspective of this cost analysis was that of the Ontario Ministry of Health and Long-Term Care. We compared the cost of inpatient mental health care to high-support housing. Cost data were derived from a variety of sources, including health administrative data, expenditures reported by housing providers, and document analysis. RESULTS: The High Support Housing Initiative was cost saving relative to inpatient care. The average cost savings per diem were between $140 and $160. This amounts to an annual cost savings of approximately $51,000 to $58,000. When tested through sensitivity analysis, the intervention remained cost saving in most scenarios; however, the result was highly sensitive to health system costs for clients of the High Support Housing Initiative program. CONCLUSIONS: This study suggests the High Support Housing Initiative is potentially cost saving relative to inpatient hospitalization at the Centre for Addiction and Mental Health.

AB - Well diffusion method was used to evaluate the antibacterial activity of Eucalyptus camaldulensis, while the antifungal effect was assessed by calculating the reduction percent in the radial growth of mycelia. The inhibition zones exerted by E. camaldulensis crude extracts varied significantly (p <= 0.01). The capsule crude extract (acetone 30%) highly inhibited the growth of Acinetobacter baumannii (35 mm clear zone). The highest antifungal activity was against Rhizopus stolonifer with a reduction percent in its radial growth reached to 96%. The bacterial MICs ranged from 20 to 0.5 mg/mL against Escherichia coli and Bacillus subtilis respectively. The MIC values for fungi were between 18 mg/mL (Mucor sp.) and 4 mg/mL (R. stolonifer). Both type and concentration of the solvent greatly affected the antimicrobial potentials of E. camaldulensis. The empty capsule and bud of E. camaldulensis are recognized for the first time as potentially natural resources of effective antimicrobial agents.

AB - : Fractures of the lateral process of the talus are uncommon, but often overlooked. They can result in significant functional deficit with residual nonunion and arthritis if not recognized and treated appropriately. We describe 2 cases of such injuries, one with acute recognition and management, and one with delayed diagnosis and nonunion. In both cases, pain from the fracture was accompanied by symptoms of instability requiring simultaneous lateral ligament reconstruction along with fracture fixation. Evaluation of patients with lateral process fractures should include assessment of the lateral ligaments; ankle instability may need to be surgically addressed along with intervention for fracture fixation.

AB - : Plantar dislocation of the first metatarsophalangeal (MTP) joint is exceedingly rare, and in prior reported cases, simple closed manipulation easily enabled reduction. We present here the first reported plantar dislocation that failed closed manipulation. We also report a technique involving injection of saline into the joint to facilitate reduction. The saline insufflation likely relieves buttonholing of the metatarsal head through the dorsal joint capsule. For first MTP joint plantar dislocations that fail reduction with manipulation, we recommend attempting injection of the joint with saline prior to subjecting the patient to open reduction.

AB - Objective The objective was to evaluate the proliferating, migratory and extracellular matrix (ECM) forming potential of annulus fibrosus cells derived from early (edAFC) or advanced (adAFC) degenerative tissue and their usability as a possible cell source for regenerative approaches for AF closure. Design EdAFC ( n = 5 Pfirrman score of 2-3) and adAFC (n = 5 Pfirrman score of 4-5) were isolated from tissue of patients undergoing spine stabilizing surgery. Cell migration on stimulation with human serum (HS), platelet-rich plasma (PRP), and transforming growth factor beta-3 (TGFB3) was assessed by migration assay and proliferation was assessed on stimulation with HS. Induction of ECM synthesis was evaluated by gene expression analysis of AF-related genes in three-dimensional scaffold cultures that have been stimulated with 5% PRP or 10 ng/mL TGFB3 and histologically by collagen type I, type II, alcian blue, and safranin-O staining. Results EdAFC and adAFC were significantly attracted by 10% HS and 5% PRP. Additionally, both cell groups proliferated under stimulation with HS. Stimulation with 10 ng/mL TGFB3 showed significant induction of gene expression of collagen type II and aggrecan, while 5% PRP decreased the expression of collagen type I. Both cell groups showed formation of AF-like ECM after stimulation with TGFB3, whereas stimulation with PRP did not. Conclusions Our study demonstrated that AF cells retain their potential for proliferation, migration, and ECM formation independent of the degeneration status of the tissue. Proliferation, migration, and ECM synthesis of the endogenous AF cells can be supported by different supplements. Hence, endogenous AF cells might be a suitable cell source for a regenerative repair approaches.

Those compounds were isolated and purified by various column chromatographic methods and their structures were elucidated by spectroscopic (1D, 2D NMR, and HR-MS) chemical analyses. All compounds were isolated for the first time from E. alatavica Boiss, and biochemical pathway of the new compound has been hypothesized. Furthermore, these compounds were evaluated for antioxidant properties based on the DPPH radical scavenging activities. Results showed that IC50 values of compounds 1, 3, 4, 5 and 6 were 25.69, 1.88, 2.87, 11.55 and 17.81 MUg/mL, respectively, as compared to the control ascorbic acid (5.34 MUg/mL). PMID- 29577752 TI - Fungal burden exposure assessment in podiatry clinics from Ireland. AB - : Fungi are amongst the bioaerosols of most importance, as indicated by the growing interest in this field of research. The aim was to characterize the exposure to fungal burden in podiatry clinics using culture-based and molecular methods. METHODS: Airborne fungi were collected using an impaction air sampler and surface samples were also performed. Fourteen air samples were collected for direct detection of fungal DNA from filamentous fungi and dermatophytes. Overall, 63.6 % of the evening samples and 46 % of the morning samples surpassed the threshold values (150 CFU/m3). Molecular detection, by real time PCR, of the target fungal species/strains (Aspergillus and Stachybotrys species) was negative for all samples collected. Trichophyton rubrum was detected by PCR analysis in one DNA sample collected on day six. Results suggest the use of both culture based and molecular methodologies are desirable for a complete evaluation of fungal burden in this particular health care setting.

AB - The total steroidal saponins, particularly its major steroidal sapogenin (diosgenin), are the main active principles of fenugreek seed extract. In this study, an ethanol-salt aqueous two-phase system (ATPS) was explored for the purification of the total steroidal saponins, and the process conditions were optimized by response surface methodology (RSM). Under the optimized conditions, the RSM predicted recovery of the total steroidal saponins in the top phase of ATPS was 97.9%, which agreed with the average experimental recovery (98.3 +/- 4.2% (n = 6)). Moreover, a rapid micellar electrokinetic chromatography (MEKC) method was developed for the determination of diosgenin from extracts. The diosgenin content in the ATPS top phase extract was 3-fold higher than that in crude extract, suggesting this ATPS having a great potential for purification pharmacological active ingredients from fenugreek seeds. PMID- 29577754 TI - A Multivariate Analysis of the Pathological Narcissism Inventory's Nomological Network. AB - The Pathological Narcissism Inventory (PNI) has enjoyed widespread use in the study of the narcissism. However, questions have been raised about whether the PNI's grandiosity scale adequately captures narcissistic grandiosity as well as other popular measures do. Specifically, some have noted that PNI grandiosity shows a pattern of external associations that diverges from patterns for narcissistic grandiosity predicted by experts, and is more similar to the predictions for the vulnerability scale than is desirable. Previous research driving these critiques has relied on patterns of zero-order correlations to examine the nomological networks of these scales. The present study reexamines the nomological networks of PNI grandiosity and vulnerability scales using hierarchical regression. Results indicate that once accounting for overlapping variance of vulnerability and grandiosity, the unique variance in the PNI's grandiosity scale closely matches contemporary expert conceptualizations of narcissistic grandiosity based on expected associations with other personality variables.

AB - The inhibition of the delta-class carbonic anhydrase (CAs, EC 4.2.1.1) from the diatom Thalassiosira weissflogii, TweCAdelta, was investigated using a panel of 36 mono- and di-thiocarbamates chemotypes that have recently been shown to inhibit mammalian and pathogenic CAs belonging to the alpha- and beta-classes. TweCAdelta was not significantly inhibited by most of such compounds (KI values above 20 uM). However, some aliphatic, heterocyclic, and aromatic mono and di thiocarbamates inhibited TweCAdelta in the low micromolar range. For some compounds incorporating the piperazine ring, TweCAdelta was effectively inhibited (KIs from 129 to 791 nM). The most effective inhibitors identified in this study were 3,4-dimethoxyphenyl-ethyl-mono-thiocarbamate (KI of 67.7 nM) and the R enantiomer of the nipecotic acid di-thiocarbamate (KI of 93.6 nM). Given that the activity and inhibition of this class of enzyme have received limited attention until now, this study provides new molecular probes and information for investigating the role of delta-CAs in the carbon fixation processes in diatoms, which are responsible for significant amounts of CO2 taken from the atmosphere by these marine organisms. PMID- 29577756 TI - Identification of cisplatin-binding sites on the large cytoplasmic loop of the Na+/K+-ATPase. AB - Cisplatin is the most widely used chemotherapeutic drug for the treatment of various types of cancer; however, its administration brings also numerous side effects. It was demonstrated that cisplatin can inhibit the Na+/K+-ATPase (NKA), which can explain a large part of the adverse effects. In this study, we have identified five cysteinyl residues (C452, C456, C457, C577, and C656) as the cisplatin binding sites on the cytoplasmic loop connecting transmembrane helices 4 and 5 (C45), using site-directed mutagenesis and mass spectrometry experiments. The identified residues are known to be susceptible to glutathionylation indicating their involvement in a common regulatory mechanism. PMID- 29577757 TI - Association between sperm mitochondrial ND2 gene variants and total fertilization failure. AB - : The objective of this study was to explore the association of sperm mitochondrial ND2 (MT-ND2) gene variants with total fertilization failure (TFF). A retrospective comparative study of 246 cases of fresh in vitro fertilization (IVF) cycles or half-intracytoplasmic sperm injection cycles in the Han Chinese population was performed from July 2011 to May 2017. A total of 59 cases undergoing TFF, and 187 control cases with normal fertilization (fertilization rates >50%) were included. The sperm mitochondrial genovariation was determined using nested sequencing. A total of 32 homoplasmic variants and 47 heteroplasmic variants of MT-ND2 gene were observed in this study. There were no significant differences in the frequencies of the 32 homoplasmic variants of MT-ND2 gene between the TFF and control groups. A total of 53 pair-wise comparisons were performed, and the general characteristics of the IVF failure and control subjects were adjusted in logistic models. Data suggested that there were no significant differences in the frequencies of point 4914, 5320, and 5426 heteroplasmic variants of MT-ND2 gene between the TFF and control groups. In addition, no significant difference was observed in the frequency of mtDNA haplogroup D or haplogroup G between the IVF failure group and the normal fertilization group. This study suggests that the MT-ND2 gene variants might not be associated with TFF.

PMID- 29577758 TI - Petroleum coke exposure leads to altered secretome profiles in human lung models. AB - Petroleum coke (PC) is a coal-like product that is produced during the refinement of crude oil and bituminous sand. Fugitive dust from open storage of PC in urban areas is a potential human health concern. Animal inhalation studies suggest that PC leads to an adverse pulmonary histopathology, including areas of fibrosis and chronic inflammation; however, little is known about its impact on human health. In order to identify biomarkers and cellular pathways that are associated with exposure, we performed two-dimensional liquid chromatography-mass spectrometric analyses on secreted proteins from two human lung culture models. A total of 2795 proteins were identified and relatively quantified from an immortalized cell line and 2406 proteins from primary cultures that were either mock treated or exposed to particulate matter with a diameter of 2.5-10 MUm PC or filtered urban air particulates for 16 h. Pathway analysis on secretomes from primary lung cultures indicated that PC exposure suppressed the secretion of proteins involved in the organization of the extracellular matrix and epithelial differentiation. Because these cellular processes could facilitate fibrosis, we performed chronic 12-day exposure studies on three-dimensional human lung cultures consisting of epithelia and stromal fibroblasts. Relative to mock-treated cells, matrix metallopeptidase 9 levels in the conditioned media were lower by 4 days postexposure and remained suppressed for the duration of the experiment. Immunocytochemical staining of collagen III, a marker associated with fibrosis, showed increased accumulation in the epithelial layer and at the air-liquid interface.

AB - INTRODUCTION: Pertussis (whooping cough) is an acute respiratory tract infection caused by Bordetella pertussis that is characterized by a chronic, severe cough. The optimum immunization schedule for pertussis is unclear, so these vary by countries. AIM: To estimate the seroprevalence of pertussis in adults in Hungary. METHOD: Serum anti-pertussis toxin immunoglobulin G (anti-PT IgG) antibody levels were analyzed using enzyme-linked immunosorbent assay in adults in general practitioners' practices during one year. Sera were classified following manufacturer's instructions as: strongly indicative of current/recent infection (>=1.5 optical density [OD] units); indicative of current/recent infection (>=1.0 OD units); seropositive (>0.3 OD units); or seronegative (<=0.3 OD units). RESULTS: 1999 adults (60.6% female; mean age 47.4 +/- 17.7 years) were included. 14.8% were seropositive, 1.1% were indicative of current/recent infection, and 0.1% were strongly indicative of current/recent infection. CONCLUSIONS: 85.2% of the subjects were seronegative and therefore susceptible to pertussis infection. Approximately 1% was suspicious of current/recent pertussis infection, potentially transmissible to susceptible young infants. Vaccination of adults is a key way to indirectly protect infants.

There are only a few data available on the results of surgical treatment, therefore the optimal treatment is unclear. Our objective was the retrospective analysis of the perioperative morbidity and mortality of patients who underwent iliac artery surgery as well as the comparison of elective open surgery and endovascular iliac aneurysm repair (EVIAR). METHOD: Retrospective analysis of patients who underwent surgery for iliac artery aneurysm between 1 January 2005 and 31 December 2014. RESULTS: During the 10-year period, 62 patients with a mean age of 68.9 years underwent elective surgery for iliac artery aneurysm (54 males, 87.1%). In 10 cases acute surgery was performed due to aneurysm ruptures (13.9%), 3 patients died within the perioperative period (30%). Regarding anatomical localisation, aneurysm developed mostly on the common iliac artery (80.6%). As an elective surgery, 35 patients (56.5%) underwent open surgery, 25 (40.3%) underwent EVIAR and other endovascular interventions were performed in 2 cases (3.2%). Postoperative complications (1 patient [4.0%] vs. 17 patients [48.5%]; p<0.001) and intensive care treatment (29 patients [82.8%] vs. 2 patients [8.0%]; p<0.001) were significantly rarer after EVIAR than after open surgery. Furthermore, EVIAR resulted in considerably shorter postoperative hospital stays (4.7 +/- 2.3 days vs. 11.8 +/- 12.2 days; p = 0.006) and significantly less blood transfusion demand (1 patient [4.0%] vs. 26 patients [74.2%]; p<0.001). There were no significant differences regarding long-term survival rates between EVIAR and open surgery (81.4% vs. 71.4%; p = 0.95). CONCLUSION: In case of the surgical treatment of iliac artery aneurysms, owing to the lower complication rates and shorter postoperative length of stay, EVIAR is primarily recommended.

AB - Mucositis is the most common oral complication of cancer therapy. Oral mucositis in childhood is more frequent and severe compared to adults, especially in children with leukemia. Lesions develop as the chemotherapeutic agents attack the rapidly dividing cells of the oral mucous membrane. Patients may experience trouble in eating, drinking, swallowing or even speaking due to the significant pain caused by the ulceration of the oral mucosa. Oral mucositis has a direct impact on the quality of life and may affect survival. The regular assessment of the oral mucosa is crucial during chemotherapy to evaluate the effectiveness of the oral mucositis prevention and treatment. Several oral mucositis scoring tools have been developed for adults to qualify the symptoms, but there is no universally accepted assessment scale for children. The prevention and treatment of therapy-related mucositis is difficult, though several methods and pharmacologic agents have been tested. Here we discuss the pathogenesis of chemotherapy-induced oral mucositis, the available assessment tools and their applicability to pediatric patients and the available therapeutic and preventive strategies.

AB - INTRODUCTION AND AIM: The unreliable quality of online health contents poses a serious challenge to the medical profession. Evaluating websites on the basis of their credibility increases the chance for readers to access professional content of better quality. Hungary still lags behind in taking practical steps to improve the quality and reliability of online patient education. METHOD: EgeszsegKommando (HealthCommando) is a new Hungarian objective scoring system established to evaluate the credibility of health related websites. It uses four types of indicators: transparency, content, recommendations, references. RESULTS: We evaluated 122 websites with EgeszsegKommando. Out of this, 22.1% qualified as credible. The same assessment using JAMA benchmarks yielded only one credible website (0.8%). The most frequent deficiencies were the absence of reference to source, the omission of the quote that "the website information does not replace the doctor-patient discussion", and the identity of the author. In 45.9% of the cases, however, the content was written by medical professionals with contact information. CONCLUSION: By applying different types of credibility and quality indicators in a scoring system, EgeszsegKommando can efficiently assess the websites on health-awareness. In cases where the recognized indicators are absent multiple times from a website, it will not pass the credibility test. Thus, EgeszegKommando can act as a filter. At the same time, EgeszsegKommando is also capable of assessing webpages of different sorts systemically, and can recommend a proportionately large amount of reliable Hungarian medical web resources to those interested.

AB - Dilated cardiomyopathy is the main cause of heart transplantation. The etiology is unknown in almost half of the cases. Many cardiac specific antibodies have been identified till now which can cause decreased cardiac function, ventricular tachycardia or sudden heart death. The prognosis of DCM is poor despite the development of medical treatment. Immunoadsorption is hopeful since, with the removal of antibodies, cardiac function and NYHA class can improve and LVAD/heart transplantation-free survival can be prolonged. At the University of Debrecen, Faculty of Medicine, Department of Internal Medicine, Division of Angiology, Intensive Care and Therapeutic Apheresis Unit we performed the first immunoadsorption. Our patient was a 43-year-old man with idiopathic dilated cardiomyopathy, NYHA class IV, a heart transplantation candidate, whose cardiac specific antibody, type IgG was indentified by Western blot. Before the treatment he had ejection fraction of 18%. Discussing with his cardiologists we decided for immunoadsorption therapy. We performed 5 cycles on consecutive days in Intensive Care Unit. After 1 month we detected improvement in exercise capacity. We detected improvement in isovolemic contraction (from 465 mmHg/s to 575 mmHg/s), increased stroke volume (from 49 ml to 66 ml). After 3 months we repeated SPECT investigation which showed improvement in ejection fraction, from 18% to 32%. Orv Hetil. 2018; 159(13): 532-536. PMID- 29577765 TI - Incidence of Drug Interactions Identified by Clinical Pharmacists in Veterans Initiating Treatment for Chronic Hepatitis C Infection. AB - BACKGROUND: Many direct-acting antivirals (DAAs) have drug-drug interactions (DDIs) with the potential to affect efficacy and safety. OBJECTIVE: To describe the incidence and severity of DDIs with DAAs identified by the hepatitis C virus (HCV) clinical pharmacist within a Veterans Affairs health care system. METHODS: This single-center, retrospective cohort study evaluated patients with HCV treated with DAA therapy. Primary end points included the total number of identified DDIs, percentage of patients with at least 1 DDI, mean number of DDIs per patient, and the number of DDIs by severity category. Additional end points included characterization of interacting drugs, clinical consequence of interaction, intervention recommended, acceptance rate of actionable recommendations, and achievement of sustained virological response 12 weeks after treatment (SVR12). RESULTS: A total of 300 patients were included. There were 554 identified DDIs, and 80.3% of patients had at least 1 DDI, with an average of 1.85 DDIs per patient; 76% of the DDIs identified were categorized as either a potentially clinically significant or critical interaction. The most common DDIs involved acid suppression agents (20%). Patient monitoring was the most commonly recommended intervention (59%), followed by dose modification of the interacting medication (30%). There was no difference in SVR12 between patients with at least 1 DDI compared with those with no DDIs (94.8% vs 95.8%; P = 0.73). There were a total of 227 actionable recommendations, with an acceptance rate of 84.1%. CONCLUSIONS: This study suggests that DDIs are prevalent among patients treated with DAAs for HCV. A HCV clinical pharmacist can help optimize patient care by identifying DDIs and recommending interventions to providers. PMID- 29577766 TI - Cost of Prescription Drug-Related Morbidity and Mortality. AB - BACKGROUND: Public attention and recent US Congressional activity has intensified focus on escalating medication prices. However, the actual cost of medication use extends beyond the up-front cost of purchasing medicines. It also encompasses the additional medical costs of morbidity and mortality resulting from nonoptimized medication regimens, including medication nonadherence. OBJECTIVES: Applying the most current nationally representative data sources, our goal was to estimate the cost of prescription drug-related morbidity and mortality in the United States. METHODS: Total costs of nonoptimized prescription drug use and average pathway costs for a patient who experienced a treatment failure (TF), a new medical problem (NMP), or a TF and NMP were modeled in Microsoft Excel (Microsoft Corporation, Redmond, WA) and TreeAge Pro Healthcare, v2014 (TreeAge Software, Inc, Williamstown, MA), respectively. RESULTS: The estimated annual cost of prescription drug-related morbidity and mortality resulting from nonoptimized medication therapy was $528.4 billion in 2016 US dollars, with a plausible range of $495.3 billion to $672.7 billion. The average cost of an individual experiencing TF, NMP, or TF and NMP after initial prescription use were $2481 (range: $2233, $2742), $2610 (range: $2374, $2848) and $2572 (range: $2408, $2751), respectively. CONCLUSIONS: The estimated annual cost of drug-related morbidity and mortality resulting from nonoptimized medication therapy was $528.4 billion, equivalent to 16% of total US health care expenditures in 2016. We propose expansion of comprehensive medication management programs by clinical pharmacists in collaborative practices with physicians and other prescribers as an effective and scalable approach to mitigate these avoidable costs and improve patient outcomes.

PMID- 29577768 TI - Antithrombotic Therapy in Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention: Where Are We Now? AB - OBJECTIVE: To synthesize the literature and provide guidance to practitioners regarding double therapy (DT) and triple therapy (TT) in patients with atrial fibrillation (AF) requiring percutaneous coronary intervention (PCI). DATA SOURCES: PubMed and MEDLINE (January 2000 to February 2018) were searched using the following terms: atrial fibrillation, myocardial infarction, acute coronary syndrome, percutaneous coronary intervention, anticoagulation, dual-antiplatelet therapy, clopidogrel, aspirin, ticagrelor, prasugrel, and triple therapy. STUDY SELECTION AND DATA EXTRACTION: The results included randomized and nonrandomized clinical trials and meta-analyses. Each study was reported based on study design, population, intervention, comparator, and key cardiovascular (CV) and bleeding outcomes. DATA SYNTHESIS: A total of 15 studies were included in the review. The majority of studies evaluating DT and TT utilized clopidogrel and warfarin as components of the regimen, although there are emerging data with newer agents. Evidence purporting DT regimens to be equally effective in preventing CV events and improved safety profiles compared with TT regimens included populations with relatively low risk for recurrent CV events, and many of these studies were observational in nature. Overall, current evidence as well as American and European guidelines support the use of TT in patients with AF who require PCI for the least possible amount of time, depending on patient-specific factors involving bleeding and thrombosis. CONCLUSIONS: In the majority of patients with AF who require PCI, TT should be used for the shortest period of time possible. DT regimens may be used in patients requiring PCI who have low risk for thrombosis and/or high bleeding risk. PMID- 29577769 TI - Perceptions of Healthy Eating Among Hispanic Parent-Child Dyads. AB - Limited research exists exploring the perceptions of healthy and unhealthy eating among Hispanic families, yet understanding their perceptions could inform public health practice with regard to nutrition and obesity prevention. This study conducted an exploratory analysis of interview data collected from 25 parent child dyads as part of a program evaluation to learn more about both parent and child beliefs and practices regarding healthy eating, and in particular fruit and vegetable consumption. Families described an incomplete knowledge regarding healthy eating, specifically how to increase fruit and vegetable consumption, and the benefits of healthy eating as well as risks of unhealthy eating. Parents in particular seemed to identify many of the foods to avoid but were unclear about healthier alternatives. Children focused more on the benefits of healthy eating, while parents spoke more about the risks of unhealthy eating and the challenges of eating vegetables, particularly among families where child weight was also raised as a concern. PMID- 29577770 TI - Enrolling Underserved Women in mHealth Programs: Results From Text4baby Outreach Campaigns. AB - Public health practitioners have increasingly leveraged technology-based communication to get health information into the hands of hard-to-reach populations; however, best practices for outreach and enrollment into mobile health (mHealth) programs are lacking. This article describes enrollment results from campaigns focused on enrolling underserved pregnant women and mothers in Text4baby-a free, mHealth service-to inform outreach strategies for mHealth programs. Text4baby participants receive health and safety information, interactive surveys, alerts, and appointment reminders through at least three weekly texts and a free app-timed to users' due date or babies' birth date. Text4baby worked with partners to implement national, state, and community-based enrollment campaigns. Descriptive statistics were used to compare baseline enrollment prior to a campaign with enrollment during a campaign to generate enrollment estimates. Enrollment rates were calculated for campaigns for which the number targeted/reached was available. National television campaigns resulted in more than 10,000 estimated enrollments. Campaigns that were integrated with an existing program and text-based recruitment had the highest enrollment rates, ranging from 7% to 24%. Facebook advertisements and traditional media targeting providers and consumers were least effective. mHealth programs should consider text-based recruitment and outreach via existing programs; additional research is needed on return on investment for different outreach strategies and on the effectiveness of different outreach strategies at reaching and enrolling specific target populations. PMID- 29577772 TI - Training Community Health Workers in Motivational Interviewing to Promote Cancer Screening. AB - Health disparities researchers attempting to engage and effectively deliver interventions to underserved populations often encounter a number of challenges ranging from geographical considerations to more complex issues of medical mistrust. While there are a number of strategies researchers may employ to address these challenges, one of the most successful of these has been the use of community health workers (CHWs). Despite the documented success of CHWs, little information exists on the use of theory-driven intervention strategies with these community partners. Researchers who have partnered with CHWs tend to provide brief descriptions of training strategies and provide little discussion of the challenges and barriers to training a lay population in the delivery of technical interventions, including ensuring fidelity to the intervention protocol. The purpose of this article is to describe the feasibility of training CHWs to deliver a motivational interviewing intervention to promote cancer screening in underserved populations. With this article we present an innovative way to use motivational interviewing delivered by CHWs. Specifically, we will detail the development of the training protocol, the implementation of that training in a variety of research settings, and the development and implementation of fidelity protocols. We will use examples from two research studies where CHWs were successfully trained to use MI to promote cancer screening in underserved communities to highlight the challenges and barriers faced in developing and implementing the training and strategies used to overcome these challenges during the refinement of the intervention. PMID- 29577771 TI - A Participatory Process to Engage Appalachian Youth in Reducing Sugar-Sweetened Beverage Consumption. AB - Children and adolescents consume excessive amounts of sugar-sweetened beverages (SSBs), which are associated with adverse health outcomes. We describe a yearlong participatory research study to reduce SSBs in Central Appalachia, where excessive consumption is particularly prevalent. This study was conducted in partnership with a community advisory board in Southwest Virginia. Nine "youth ambassadors," aged 10 to 13 years helped to systematically adapt SIPsmartER, an effective theory-based program for Appalachian adults, to be age and culturally appropriate and meet desired theoretical objectives. They then assisted with delivering the curriculum during a school-based feasibility study and led an advocacy event in their community. Satisfaction surveys and feedback sessions indicate that ambassadors found the program acceptable and important for other students. Validated surveys and focus groups suggested that theoretical objectives were met. Findings from these mixed methods sources informed curricular changes to further enhance acceptability and refine theoretical objectives. Participation in follow-up advocacy activities was tracked and described. Following the yearlong study, ambassadors reported having advocacy skills and motivation to continue reducing SSB intake in their community. Results, challenges, and lessons learned are presented to inform larger efforts to enhance acceptability of programs and inspire youth to take action to reduce health disparities in Appalachian communities.

AB - Cancer Ward 12 is an ongoing creative project concerned with expressing and articulating, through art, the physical, emotional and social impact of a cancer diagnosis. The first stage of the project was carried out through an artist residency on the general oncology ward, locally known as Ward 12, at Singleton Hospital in Swansea, Wales, in November 2016, and this led to a public exhibition of artwork, launched in Swansea in May 2017. This paper focuses on the methodology and rationale behind the Cancer Ward 12 project, and on the nature of the relation between creative practice and medical science. PMID- 29577776 TI - Comparison of barbed unidirectional suture with figure-of-eight standard sutures in vaginal cuff closure in total laparoscopic hysterectomy. AB - The aim of the study was to compare postoperative vaginal cuff complications due to the use of barbed sutures (V-LocTM 180 unidirectional suture; Covidien, Mansfield, MA) and standard braided sutures (Vicryl(r); Ethicon Inc., Somerville, MA) during vaginal cuff closure of patients undergoing a total laparoscopic hysterectomy (TLH) due to benign diseases. Eighty-nine patients were in the standard suture group and 208 patients were included in the barbed suture group. Vaginal cuff dehiscence was identified in only three (3.3%) patients within the standard suture group and none in the barbed suture group. Five (5.6%) patients in the standard suture group and two (0.9%) patients in the barbed suture group developed postoperative cuff infection/cellulitis. Duration of the surgery was significantly shorter in the barbed suture group than in the standard suture group (p < .05). V-LocTM 180 unidirectional barbed suture, which is used during TLH for vaginal cuff closure, is an applicable, safe and tolerable alternative to a standard suture. IMPACT STATEMENT What is already known on this subject: Barbed sutures are a relatively new type of suture that include sharp barbs inserted on monofilament material in various configurations, and are used for approximating tissues without any need for surgical knotting. They have increasingly been used in obstetrics and gynaecology in recent years, particularly in total laparoscopic hysterectomy and laparoscopic myomectomy. At present, there are a limited number of studies of V-LocTM suture in the literature. What the results of this study add: We demonstrated that barbed sutures used for enabling vaginal cuff integrity did not cause major morbidity and mortality for the patient. We suggest that V LocTM 180 barbed sutures offer a practical, safe and tolerable alternative for surgeons because they are easy to use, do not cause a significant increase in vaginal cuff complications, and shorten the operating time. Our study with V LocTM 180 unidirectional barbed suture is the second largest series after the study of Cong et al. What the implications are of these findings for clinical practice and/or further research: We believe that the barbed suture, the surgery results of which are openly discussed in our study, will be more prominent in clinical practice owing to the shortened operating time, and that the use of these sutures does not cause a significant increase in vaginal cuff complications. PMID- 29577777 TI - Factors associated with spontaneous perineal lacerations in deliveries without episiotomy in a university maternity hospital in the city of Recife, Brazil: a cohort study. AB - OBJECTIVES: The objective of this study is to determine factors associated with spontaneous perineal laceration in low-risk pregnant women who delivered vaginally without episiotomy in a university maternity hospital in Recife, Pernambuco, Brazil. METHODS: A prospective cohort study was conducted with 222 low-risk, full-term pregnant women admitted in labor with a single fetus in cephalic presentation. Women with malformed fetuses were excluded from the study. The variables analyzed were: the frequency and severity of lacerations, the women's biological, sociodemographic, clinical and obstetrical characteristics, neonatal characteristics, and data on their deliveries and procedures. For the data analysis, risk ratios and their 95% confidence intervals were calculated. A significance level of 5% was adopted and multiple regression analysis was performed. RESULTS: Spontaneous first-degree perineal tears were registered in 47% of the women, second-degree tears in 31%, and third degree tears in only 1.8%. There were no cases of fourth-degree tears. Having experienced normal childbirth previously constituted a protective factor against vaginal tearing (OR = 0.46; 95%CI: 0.23-0.91; p = .027). CONCLUSION: The principal protective factor against spontaneous lacerations was having experienced normal childbirth previously. Intrapartum strategies aimed at protecting the perineum and pelvic floor muscle training during prenatal care should be encouraged in these women. PMID- 29577778 TI - Management of Postfasciotomy Wounds and Skin Defects Following Complex Vascular Trauma to the Extremities Using the External Tissue Extender System. AB - Management of large postfasciotomy wounds and/or skin and soft tissue defects after major vascular trauma to the extremities can be challenging. The External Tissue Extender (Blomqvist; ETE), a skin-stretching device, which consists of silicone tapes and plastic stoppers, approximates wound margins and facilitates delayed primary closure. We describe our experience with the use of ETE in 5 patients (4 males) with a total of 8 wounds (7 postfasciotomy, 1 soft tissue defect) over the past 12 years. The mean patient age was 32 (range 17-61) years. The wounds involved the lower limb in 3 patients and the upper limb in 2, whereas the injured arteries were the popliteal in 3, the axillary in 1, and the brachial in 1. The mean wound length was 24 cm (range 9-37 cm), and the mean number of ETE silicone tapes used per wound was 13 (range 5-19). The median duration of ETE therapy was 7 days (range 4-7). ETE therapy resulted in sufficient wound approximation to allow complete closure with conventional suturing in 7 out of the 8 wounds. Of these, one developed infection that required drainage, debridement, and resuturing. All wounds achieved satisfactory healing status and all limbs had been salvaged. In conclusion, the ETE is a useful, easy-to-use, and simple adjunct that may facilitate delayed primary closure of large postfasciotomy wounds or extensive skin and soft tissue defects following complex vascular trauma to the extremities. PMID- 29577779 TI - A review in gait rehabilitation devices and applied control techniques. AB - PURPOSE: The aim of this review is to analyse the different existing technologies for gait rehabilitation, focusing mainly in robotic devices. Those robots help the patient to recover a lost function due to neurological gait disorders, accidents or after injury. Besides, they facilitate the identification of normal and abnormal features by registering muscle activity providing the doctor important data where he can observe the evolution of the patient. METHOD: A deep literature review was realized using selected keywords considering not only the most common medical and engineering databases, but also other available sources that provide information on commercial and scientific gait rehabilitation devices. The founded literature for this review corresponds to control techniques for gait rehabilitation robots, since the early seventies to the present year. RESULTS: Different control strategies for gait analysis in rehabilitation devices have been developed and implemented such as position control, force and impedance control, haptic simulation, and control of EMG signals. These control techniques are used to analyze the force of the patient during therapy, compensating it with the force generated by the mechanism in the rehabilitation device. It is observed that the largest number of studies reported, focuses on the impedance control technique. Leading to include new control techniques and validate them using the necessary protocols with ill patients, obtaining reliable results that allows a progressive and active rehabilitation. CONCLUSIONS: With this exhaustive review, we can conclude that the degree of complexity of the rehabilitation device influences in short and long-term therapeutic results since the movements become more controlled. However, there is still a lot of work in the sense of motion control in order to perform trajectories that are more alike the natural movements of humans. There are many control techniques in other areas, which seek to improve the performance of the process. These techniques may possibly be applicable in gait rehabilitation devices, obtaining controllers that are more efficient and that adapts to different people and the necessities that entail every disease. Implications for Rehabilitation Rehabilitation helps people to improve the activities of their daily life, allowing them to observe their progress in the functional abilities as the months pass by with intensive and repetitive therapies. There is a mobility issue when the patient needs to move to the hospital or to the laboratory, which is not always feasible. For overcoming it, patients use the equipment at home to perform their daily therapy. However, they need the sufficient knowledge about its operation, also about the therapeutic movements, the therapy duration and the movement speed. Besides, is necessary to place the equipment in a proper and lively environment that helps to forget or reduce pain while the patient moves his joints progressively. The purpose of robotic rehabilitation devices is to generate repetitive and progressive movements, according to the motor disability. There are training trajectories to follow, which motivate patients to generate active movements. The benefits of robotic rehabilitation depend on the ability of each patient to adapt to the speed and load variations generated by the device, improving and reinforcing motor functions in therapy, especially in patients with advanced disabilities in early rehabilitation. Multi-joint rehabilitation devices are more effective than single-joint rehabilitation devices because they involve a higher number of muscles in the therapy. The greater the number of degrees of freedom (DoF) of the device, it cushions its effect in the patient because the inertia is reduced and higher torques are generated. The assistive technological devices allows to explore different rehabilitation techniques that motivate the patient in therapy, increasing appropriately the energy and pressure in the blood which is reflected in gradually recovering his ability to walk.

AB - INTRODUCTION: Complete placenta previa (CPP) is one of the most problematic types of abnormal placenta, which is further complicated by placenta accreta or percreta that can unexpectedly lead to catastrophic blood loss, infection, multiple complications, emergency hysterectomy, and even death. The present study aimed to assess the efficacy of random placenta margin incision in controlling intraoperative and total blood loss during cesarean section for CPP women. METHODS: A prospective cohort study, including a total of 100 consecutive pregnant women with CPP, was performed at a tertiary university-affiliated medical center between March 2016 and July 2017. All of them underwent random placenta margin incision, and intraoperative and total blood loss were analyzed. Through antenatal diagnosis using color Doppler, women were further divided into abnormally invasive placenta (AIP) and non-AIP groups, and anterior and posterior placenta groups. The protocol was registered with the Clinical Trial Registry under registration number NCT02695069. RESULTS: Mean maternal age and gestational age at delivery were 32.26 +/- 5.03 years old and 36.21 +/- 2.07 weeks, respectively. Total duration of the surgical procedure time was 52.50 (42.43 64.00) min. Median estimated intraoperation blood loss was 746.43 (544.44 1092.86) ml. Total blood loss was 875.00 (604.50-1196.67) ml, and 38 (38.0%) had post-partum hemorrhage. The change from baseline in the median hemoglobin level was -0.33 (6.00-13.20). No women underwent hysterectomy due to massive hemorrhage during the study period. No women had an intraoperative urinary bladder injury, postoperative wound infection, and required relaparotomy, owing to intra abdominal bleeding. The median hospitalization time was 5.41 (4.18-7.58) d. CONCLUSION: The random placenta margin incision may be a potentially valuable surgical procedure to control the volumes of intraoperative and postoperative blood loss and reduce the incidence of postpartum hemorrhage among women with complete placenta previa. PMID- 29577781 TI - Kurtosis-Based Detection of Intracranial High-Frequency Oscillations for the Identification of the Seizure Onset Zone. AB - Pathological High-Frequency Oscillations (HFOs) have been recently proposed as potential biomarker of the seizure onset zone (SOZ) and have shown superior accuracy to interictal epileptiform discharges in delineating its anatomical boundaries. Characterization of HFOs is still in its infancy and this is reflected in the heterogeneity of analysis and reporting methods across studies and in clinical practice. The clinical approach to HFOs identification and quantification usually still relies on visual inspection of EEG data. In this study, we developed a pipeline for the detection and analysis of HFOs. This includes preliminary selection of the most informative channels exploiting statistical properties of the pre-ictal and ictal intracranial EEG (iEEG) time series based on spectral kurtosis, followed by wavelet-based characterization of the time-frequency properties of the signal. We performed a preliminary validation analyzing EEG data in the ripple frequency band (80-250 Hz) from six patients with drug-resistant epilepsy who underwent pre-surgical evaluation with stereo-EEG (SEEG) followed by surgical resection of pathologic brain areas, who had at least two-year positive post-surgical outcome. In this series, kurtosis driven selection and wavelet-based detection of HFOs had average sensitivity of 81.94% and average specificity of 96.03% in identifying the HFO area which overlapped with the SOZ as defined by clinical presurgical workup. Furthermore, the kurtosis-based channel selection resulted in an average reduction in computational time of 66.60%. PMID- 29577782 TI - Anatomically corrected malposition of the great arteries: a challenging fetal diagnosis. AB - Anatomically corrected malposed great arteries are uncommon and benign entity. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion. In this manuscript, we described two cases in which the antenatal diagnosis of anatomically corrected malposition of great arteries was suspected and confirmed during the postnatal period. During the fetal life, this diagnosis remains a challenge and this condition is often misdiagnosed as the transposition of the great arteries (TGA). Differently to TGA, anatomically corrected malposition of the great arteries may not require any cardiac surgical intervention depending on the associated cardiac anomalies. Indeed, postnatal examination for concerns related to anomalies that can be associated with this condition, such as anomalous origins of coronary arteries and left ventricular outflow tract obstruction, should be performed. PMID- 29577783 TI - Chasing as a model of psychogenic stress: characterization of physiological and behavioral responses. AB - Being chased by a predator or a dominant conspecific can induce significant stress. However, only a limited number of laboratory studies have employed chasing by itself as a stressor. In this study, we developed a novel stress paradigm in which rats were chased by a fast-moving object in an inescapable maze. In Experiment 1, defensive behaviors and stress hormone changes induced by chasing stress were measured. During the chasing stress, the chasing-stress group (n = 9) froze and emitted 22-kHz ultrasonic vocalizations (USVs), but the no chasing control group (n = 10) did not. Plasma corticosterone levels significantly increased following the chasing and were comparable to those of the restraint-stress group (n = 6). In Experiment 2, the long-lasting memory of the chasing event was tested after three weeks. The chasing-stress group (n = 15) showed higher levels of freezing and USV than the no-chasing group (n = 14) when they were presented with the tone associated with the object's chasing action. Subsequently, the rats were subjected to Pavlovian threat conditioning with a tone as a conditioned stimulus and footshock as an unconditioned stimulus. The chasing-stress group showed higher levels of freezing and USV during the conditioning session than the no-chasing group, indicating sensitized defensive reactions in a different threat situation. Taken together, the current results suggest that chasing stress can induce long-lasting memory and sensitization of defensive responses to a new aversive event as well as immediate, significant stress responses. PMID- 29577785 TI - Botulism in pregnancy - a clinical approach to diagnosis and management. AB - Botulism is a life-threatening toxin mediated disease that often presents with a sudden rapid onset of paralysis of their skeletal muscles with subsequent respiratory compromise and sudden death. Given the natural physiological changes during pregnancy, pregnant women with botulism may experience a more exaggerated course and have worse outcomes compared to nonpregnant women. Medical providers caring for such patients should not only maintain a high level of suspicion for botulism, but administration of an antitoxin early in their care can help reduce morbidity and mortality, while awaiting confirmatory laboratory results. It is not uncommon for a medical provider caring for these women to mistakenly associate the signs and symptoms associated with botulism with pregnancy-related findings; therefore, this article illustrates a clinical algorithmic approach to caring for these women, including a systematic approach to establishing a diagnosis and management plan for pregnant women with botulism. PMID- 29577784 TI - Updated standard operating procedures for electrochemotherapy of cutaneous tumours and skin metastases. AB - Electrochemotherapy is now in routine clinical use to treat cutaneous metastases of any histology, and is listed in national and international guidelines for cutaneous metastases and primary skin cancer. Electrochemotherapy is used by dermatologists, surgeons, and oncologists, and for different degrees and manifestations of metastases to skin and primary skin tumours not amenable to surgery. This treatment utilises electric pulses to permeabilize cell membranes in tumours, thus allowing a dramatic increase of the cytotoxicity of anti-cancer agents. Response rates, often after only one treatment, are very high across all tumour types. The most frequent indications are cutaneous metastases from malignant melanoma and breast cancer. In 2006, standard operating procedures (SOPs) were written for this novel technology, greatly facilitating introduction and dissemination of the therapy. Since then considerable experience has been obtained treating a wider range of tumour histologies and increasing size of tumours which was not originally thought possible. A pan-European expert panel drawn from a range of disciplines from dermatology, general surgery, head and neck surgery, plastic surgery, and oncology met to form a consensus opinion to update the SOPs based on the experience obtained. This paper contains these updated recommendations for indications for electrochemotherapy, pre-treatment information and evaluation, treatment choices, as well as follow-up. PMID- 29577786 TI - Complicated unsafe abortion in a Nigerian teaching hospital: pattern of morbidity and mortality. AB - Addressing unsafe abortion in developing countries may propel a rapid decline in overall maternal death. A retrospective review of patients with complicated unsafe abortion was conducted in a Nigerian Tertiary Hospital. In order to provide evidence that may inform policy changes, we describe patients' clinical profiles, abortion providers, and morbidity and mortality patterns. Of 3122 gynaecological admissions, 231 (7.4%) had unsafe abortion-related complications. The majority (53.2%) of admissions were between 16 and 25 years. Single women constituted 51% while 57% were nulliparous. Common presentations were abdominal pain (62%), fever (54%) and vaginal bleeding (53%). The most frequent complications were anaemia (55%) and retained products of conception (47%). Doctors reportedly performed 42% of abortions. There were 392 maternal mortalities; 39 (9.9%) from unsafe abortions and sepsis was responsible in 31 (80%) patients. Abortion remains a major public health issue. Youths are mostly involved. Doctors were reportedly the highest abortion providers. Mortality is high, occurring mostly from sepsis. Impact Statement What is already known on this subject? Doctors are reported as being involved in a high proportion of unsafe abortions in low and middle income countries where abortion remains a significant contributor to maternal mortality and morbidity. What the results of this study add? Our study agrees with existing literature that doctors reportedly performed most of the unsafe abortions. It also found that doctors were reported as abortion providers in the majority (35.9%) of those unsafe abortions that ended in mortality. What the implications are of these findings for clinical practice and/or further research? There is a need to conduct studies that will verify the status of abortion providers rather than rely on clients' report; and also inspect facilities to confirm adherence to minimum medical standards. Such research findings will be needed prior to local and possibly national healthcare interventions and policy changes. PMID- 29577787 TI - Clinical and economic outcomes associated with the use of fluticasone propionate 250 mcg and salmeterol 50 mcg combination versus tiotropium bromide 18 mcg as initial maintenance treatment for chronic obstructive pulmonary disease in managed care. AB - AIMS: To examine the clinical and economic outcomes associated with the use of long-acting bronchodilators for initial maintenance treatment of chronic obstructive pulmonary disease (COPD) by analyzing health insurance claims data in the US. METHODS: A retrospective, observational, matched cohort study used health insurance claims data (January 2008 to June 2013) to assess COPD-related outcomes for subjects aged >=40 years. Subjects were assigned to a study cohort according to the first observed prescription fill for a long-acting bronchodilator (fluticasone propionate 250 mcg/salmeterol 50 mcg [FSC] or tiotropium bromide 18 mcg [TIO]). The analysis period for each subject comprised a 1-year pre-index date and 1-year post-index date. Primary outcome measure was total COPD-related costs per-patient per-year (PPPY) during the follow-up period. Secondary outcome measures included COPD-related exacerbations and the components of COPD-related costs. RESULTS: Overall, 24,040 subjects were identified; the analysis sample consisted of 19,090 subjects (9,545 per cohort) with no significant differences between cohorts. Mean COPD-related total costs PPPY were numerically lower among the FSC cohort; however, the difference was not statistically significant ($2,224 [+/-4,108] vs $2,352 [+/-3,721], p = .057). There was no difference between cohorts for COPD-related medical costs (p = .894). COPD-related pharmacy costs were significantly, yet modestly, lower in the FSC cohort compared with the TIO cohort ($1,160 [+/-1,106] vs 1,275 [+/-1,110], p < .001). There were no statistically significant differences in the rate or number of exacerbations between the matched cohorts. LIMITATIONS: While propensity scoring achieved balance in baseline characteristics, some residual confounding unobserved in the database may be present. CONCLUSIONS: Few clinical and economic differences between subjects initiating maintenance therapy with FSC or TIO were observed. PMID- 29577788 TI - Barrels XXX meeting report: Barrels in Baltimore.

PMID- 29577789 TI - A sandwich technique (N&H variation technique) to reduce blood loss during cesarean delivery for complete placenta previa: a randomized controlled trial. AB - OBJECTIVE: To investigate the effect of A sandwich technique Nahla & Hany variation (N&H) technique versus stepwise uterine devascularization on blood loss during cesarean section (CS) in patients with complete placenta previa. METHODS: The study was single-blind randomized controlled trial carried out in a tertiary University Hospital between March 2015 to March 2018. We included patients scheduled for CS due to complete placenta previa. They were randomly allocated to group (I) managed by stepwise uterine devascularization, group (II) managed by double transverse compression suture at the lower uterine segment plus intrauterine inflated Foley's catheter Balloon (H&N variation sandwich) at the lower uterine segment. The primary outcome was the amount of total estimated blood loss both intra- and post-operative. RESULTS: One hundred and six patients were enrolled (n = 53 in each group). There was a great reduction in intraoperative blood loss in group II 570 (400-1300) compared with Group I 1030 (500-1540) (p = .0001), or blood in the intraabdominal drain in group II than group I (p = .0001) Also, there was no significant reduction in postoperative vaginal bleeding. Hence, the total estimated blood loss in group II 750 (550 1580) showed significant reduction compared with group I 1350 (780-1800) (p = .0001). CONCLUSIONS: N&H variation sandwich technique in the management of complete placenta previa is a simple technique, safe and effective to decrease blood loss. PMID- 29577790 TI - Parent Psychological Distress in the Neonatal Intensive Care Unit Within the Context of the Social Ecological Model: A Scoping Review. AB - BACKGROUND: Neonatal intensive care unit (NICU) parents are at risk for psychological distress and impaired mental health, and statistics related to parent psychological distress vary. OBJECTIVE: To determine the scope of literature regarding the mental health and psychosocial well-being of parents in the NICU. DESIGN: A scoping review within the Arksey and O'Malley framework and the SEM was undertaken to answer, "What factors contribute to parent's mental health in the NICU?" A systematic review of the literature was performed using the PRISMA methodology. RESULTS: Common socioeconomic factors and infant and parent characteristics may place parents at a greater risk for developing distress. History of mental illness, family cohesion, birth trauma, altered parenting role, gestational age, birth weight, and severity of prematurity/illness emerged as themes. CONCLUSION: Further research is required to provide a standard for the screening and assessment of parents' mental health and psychosocial well-being during a NICU hospitalization. The experiences of nonbirth parents in the NICU should be explored to examine the effects of the hospitalization on all types of parents. PMID- 29577791 TI - Automated detection and classification of the proximal humerus fracture by using deep learning algorithm. AB - Background and purpose - We aimed to evaluate the ability of artificial intelligence (a deep learning algorithm) to detect and classify proximal humerus fractures using plain anteroposterior shoulder radiographs. Patients and methods 1,891 images (1 image per person) of normal shoulders (n = 515) and 4 proximal humerus fracture types (greater tuberosity, 346; surgical neck, 514; 3-part, 269; 4-part, 247) classified by 3 specialists were evaluated. We trained a deep convolutional neural network (CNN) after augmentation of a training dataset. The ability of the CNN, as measured by top-1 accuracy, area under receiver operating characteristics curve (AUC), sensitivity/specificity, and Youden index, in comparison with humans (28 general physicians, 11 general orthopedists, and 19 orthopedists specialized in the shoulder) to detect and classify proximal humerus fractures was evaluated. Results - The CNN showed a high performance of 96% top-1 accuracy, 1.00 AUC, 0.99/0.97 sensitivity/specificity, and 0.97 Youden index for distinguishing normal shoulders from proximal humerus fractures. In addition, the CNN showed promising results with 65-86% top-1 accuracy, 0.90-0.98 AUC, 0.88/0.83 0.97/0.94 sensitivity/specificity, and 0.71-0.90 Youden index for classifying fracture type. When compared with the human groups, the CNN showed superior performance to that of general physicians and orthopedists, similar performance to orthopedists specialized in the shoulder, and the superior performance of the CNN was more marked in complex 3- and 4-part fractures. Interpretation - The use of artificial intelligence can accurately detect and classify proximal humerus fractures on plain shoulder AP radiographs. Further studies are necessary to determine the feasibility of applying artificial intelligence in the clinic and whether its use could improve care and outcomes compared with current orthopedic assessments. PMID- 29577792 TI - Relation of Diabetes to Cognitive Function in Hispanics/Latinos of Diverse Backgrounds in the United States. AB - OBJECTIVES: To examine the association between diabetes and cognitive function within U.S. Hispanics/Latinos of Central American, Cuban, Dominican, Mexican, Puerto Rican, and South American background. METHOD: This cross-sectional study included 9,609 men and women (mean age = 56.5 years), who are members of the Hispanic Community Health Study/Study of Latinos. We classified participants as having diabetes, prediabetes, or normal glucose regulation. Participants underwent a neurocognitive battery consisting of tests of verbal fluency, delayed recall, and processing speed. Analyses were stratified by Hispanic/Latino subgroup. RESULTS: From fully adjusted linear regression models, compared with having normal glucose regulation, having diabetes was associated with worse processing speed among Cubans (beta = -1.99; 95% CI [confidence interval] = [ 3.80, -0.19]) and Mexicans (beta = -2.26; 95% CI = [-4.02, -0.51]). Compared with having normal glucose regulation, having prediabetes or diabetes was associated with worse delayed recall only among Mexicans (prediabetes: beta = -0.34; 95% CI = [-0.63, -0.05] and diabetes: beta = -0.41; 95% CI = [-0.79, -0.04]). No associations with verbal fluency. DISCUSSION: The relationship between diabetes and cognitive function varied across Hispanic/Latino subgroup. PMID- 29577793 TI - Can we predict levator ani muscle avulsion in instrumental deliveries through intrapartum transperineal ultrasound? AB - INTRODUCTION: To determine whether intrapartum translabial ultrasound (ITU) is useful for the prediction of levator ani muscle (LAM) avulsions in instrumental deliveries (vacuum and forceps). MATERIALS AND METHODS: Prospective, observational study, including (1/2016 - 5/2016) 77 nulliparous women, with singleton pregnancies of >=37 weeks of gestation and with cephalic presentation, who required vacuum or forceps instrumentation to complete the delivery. The ITU parameters evaluated were Angle of Progression (AoP), Progression Distance (PD), Head Direction (HD), and Midline Angle (MLA), both at rest and with maternal push. Evaluation of LAM avulsion was performed at 6 months postpartum with 3-4D transperineal ultrasound. Complete avulsion was defined as an abnormal insertion of LAM in the lower pubic branch identified in all three central slices. RESULTS: Data from 48 nulliparous women were finally included in the study (34 vacuum and 14 forceps). We observed no difference in obstetric parameters between the two study groups (group with avulsion of LAM -14 cases, 29.2% - and group without avulsion of LAM -34 cases, 70.8%). The "LAM avulsion group" had an AoP and a PD of 136.7 +/- 22.4 and 43.5 +/- 15.6, respectively, versus 141.6 +/- 21.3 and 47.2 +/- 16.8 recorded in the group without avulsion (NS), respectively. We obtained a ROC curve for AoP and PD with a push of 0.66 (95% CI, 0.28-1.00) and 0.57 (95% CI, 0.39-0.75), respectively. CONCLUSIONS: ITU is not a useful technique to predict the occurrence of LAM avulsion in instrumental deliveries with vacuum or forceps. PMID- 29577794 TI - Pelvic Ring Fracture Accompanying Traumatic Thrombosis and Posterior Peritoneum Hernia in a 2-Year-Old Child: A Case Report. AB - A 2-year-old girl who was badly injured by a forklift, was presented to the emergency department with open and comminuted pelvic fracture, dislocation of right sacroiliac jointand femoral neck fracture on the left side. An urgent debridement was performed. However, postoperatively, the girl had apparent abdominal distension. The results of contrast-enhanced CT implied that the intestineherniated through the fissure formed by dislocation of the sacroiliac joint, which was confirmed during the operation. Therefore, hernia repair and reduction of the sacroiliac joint were performed by a Multidisciplinary team.With regard to patient's age, the sacroiliac joint was reduced and sutured with two absorbable anchors. The fracture healed in the following 3 months after discharge. PMID- 29577796 TI - Microwave ablation compared to thyroidectomy to treat benign thyroid nodules. AB - OBJECTIVE: Benign thyroid nodules occur commonly but only require treatment when symptomatic. Surgical treatment, once routine, has been replaced by newer technologies, such as microwave ablation (MWA). The aim of this study was to assess the efficacy, tolerability and cost of MWA compared to surgery to treat benign thyroid nodules. METHODS: After obtaining ethical approval and informed consent, a prospective trial was conducted with 52 patients who had symptomatic benign thyroid nodules. Patients were randomly assigned to receive MWA or surgical treatment. The volume reduction ratio (VRR), thyroid function, complications, HRQoL, costs and some parameters were compared. RESULTS: MWA reduced mean nodule volume by 72.3% at 3 months, 84.5% at 6 months and 92.4% at 12 months as effective as surgery in inactivating nodules, and thyroid dysfunction did not occur during 12-month follow-up for those receiving MWA. Although both MWA and surgery were safe, patients undergoing MWA had fewer cases of complications and rarely reported pain. The MWA group was superior to the surgery group in length of stay, postoperative scar length and the operation time. Compared to patients who underwent surgery, those who underwent MWA had better general health and mental health scores at 6 months and 12 months. The mean total cost of the MWA group was lower than that of the surgery group. CONCLUSION: MWA can significantly reduce nodule volume and nodule-related symptoms with more rapid recovery, more pleasing esthetic outcomes, less physiologic disruption and less expense compared to the surgery. PMID- 29577795 TI - Regional citrate-calcium anticoagulation during polymyxin-B hemoperfusion: A case series. AB - INTRODUCTION: So far, only heparin-based anticoagulation has been proposed during polymyxin-B hemoperfusion. However, postsurgical septic patients can be at high risk of bleeding due to either surgical complications or septic coagulation derangement. Consequently, heparin should not represent in some cases the anticoagulation regimen of choice in this type of patients. METHODS AND RESULTS: We present a case series of four postsurgical septic patients treated with polymyxin-B hemoperfusion using regional citrate anticoagulation. All the treatments were performed without complications. During each treatment, there were no episodes of filter clotting, no bleeding, and no metabolic complications for any of the patients. CONCLUSION: To our knowledge, this is the second published report on the use of citrate anticoagulation during polymyxin-B hemoperfusion. Our case series continued to show that regional citrate anticoagulation regimen is feasible and safe during polymyxin-B hemoperfusion treatment in postsurgical septic patients. PMID- 29577797 TI - Using Behavior Sequence Analysis to Map Serial Killers' Life Histories. AB - The aim of the current research was to provide a novel method for mapping the developmental sequences of serial killers' life histories. An in-depth biographical account of serial killers' lives, from birth through to conviction, was gained and analyzed using Behavior Sequence Analysis. The analyses highlight similarities in behavioral events across the serial killers' lives, indicating not only which risk factors occur, but the temporal order of these factors. Results focused on early childhood environment, indicating the role of parental abuse; behaviors and events surrounding criminal histories of serial killers, showing that many had previous convictions and were known to police for other crimes; behaviors surrounding their murders, highlighting differences in victim choice and modus operandi; and, finally, trial pleas and convictions. The present research, therefore, provides a novel approach to synthesizing large volumes of data on criminals and presenting results in accessible, understandable outcomes. PMID- 29577798 TI - Effects of Art Intervention Program for Siblings of Children With Cancer: A Pilot Study. AB - Siblings of children with cancer often experience negative feelings, and art intervention can help them express their feelings and overcome hardships. This study aimed to develop an Art Intervention Program to improve the psychological adaptation of siblings of children with cancer and to evaluate its effects. Participants were seventeen 7- to 10-year-old siblings of children with cancer. The program comprised 12 sessions conducted once a week. The effects of the intervention were assessed in terms of self-esteem, anxiety, depression, and problem behavior. Self-esteem significantly improved after intervention compared with pretest. Children showed improved scores in externalizing problems and total behavior problems; however, anxiety and depression did not change. The study results indicated that the art intervention program helped improve the self esteem and helped reduce somatic symptoms, aggressiveness, externalizing problems, and emotional instability among problem behaviors of siblings of children with cancer. However, the study was limited by its small sample size and the lack of a control group. Therefore, the study design allows no firm conclusions, and a randomized controlled trial is needed to investigate the effectiveness of the program. PMID- 29577799 TI - What Affects the Demand for Long-Term Care Insurance? A Study of Middle-Aged and Older Adults in Hong Kong. AB - Despite the potential of private insurance in financing long-term care (LTC), its coverage remains rather limited. This study is built on a comprehensive framework to examine the demand for LTC insurance in Hong Kong, a rapidly aging Asian society. A telephone survey was conducted in 2016 to collect data that formed a sample of 1,474 middle-aged and older adults. Multivariate analysis reveals more nuanced characteristics of Hong Kong middle-aged and older adults who tend to show a demand for LTC insurance, including: (a) being younger, better educated, relatively high status, and financially literate; (b) living with children but reluctant to be a burden on the family; (c) being in a better financial situation and able to afford premiums; and (d) anticipation of LTC needs and dependence, and a preference for formal care. This study offers preliminary evidence to understand the demand structure of the LTC insurance market in an Asian society. PMID- 29577800 TI - Cognitive Social Capital and Formal Volunteering Among Older Adults in Urban China: Does Gender Matter? AB - This study examined the moderating effect of gender on the relationship between cognitive social capital and formal volunteering among older adults in urban China. Cognitive social capital refers to individuals' perceptions of their social relationships in local communities. We used quota sampling to recruit 456 older adults aged 60 years and older from 16 communities of Gusu district, Suzhou city, in late 2015. Multiple group analysis was used to examine the proposed model. Gender had a moderating effect on the relationship between cognitive social capital and volunteering. The associations between cognitive social capital and volunteering were higher among older men than older women. The findings highlight the important role of cognitive social capital in influencing formal volunteering among older adults in urban Chinese contexts. The findings are particularly important for enhancing volunteering among older adults across different social and economic backgrounds. Policy and intervention implications are discussed. PMID- 29577801 TI - Early Identification of Barriers and Facilitators to Self-Management Behaviors in Pediatric Patients With Sickle Cell Disease to Minimize Hematopoietic Cell Transplantation Complications. AB - Hematopoietic cell transplantation (HCT) is an elective, curative treatment option for patients with sickle cell disease (SCD). Transplant requires extensive self-management behaviors to be successful. The purpose of this study was to describe potential barriers and facilitators to self-management in a group of pediatric patients with SCD prior to HCT and their medical outcomes post-HCT. A multiple case study approach was used to describe 4 pairs of transplant recipients grouped by age, donor type, and donor source. Each pair included a case with minimal and increased post-HCT complications. Complications included readmissions, graft-versus-host disease, systemic infections, and survival in the first year post-HCT. Variables were retrospectively collected and content analyzed to identify barriers and facilitators within and across pairs using existing self-management frameworks. While higher risk transplants experienced more complications, 3 of the 4 cases with increased complications had a larger number of modifiable barriers identified compared with those experiencing minimal complications. At least one modifiable barrier and multiple facilitators were identified in all cases. A standardized psychosocial assessment process with an established plan to mitigate barriers and promote facilitators to self-management is essential to optimize outcomes in patients with SCD undergoing elective HCT. PMID- 29577802 TI - Diameter of inflow as a predictor of radiocephalic fistula flow. AB - INTRODUCTION:: The optimal method for vascular access surveillance is largely unknown. A previous case-control study suggested a simplified anatomical measure obtained by Doppler ultrasound-the narrowest segment of the circuit or "minimal luminal diameter" may identify patients with a dysfunctional radiocephalic arteriovenous fistula. The relationship between minimal luminal diameter and access flow (Qa) in the radiocephalic arteriovenous fistula has not previously been studied. METHODS:: Patients undergoing Doppler ultrasound of a radiocephalic arteriovenous fistula over an 8-month period were identified retrospectively. Minimal luminal diameter was identified and demographic and clinical data were collected. Qa was estimated by Doppler estimation of brachial artery flow. The relationship between minimal luminal diameter and Qa was examined by correlation and using different levels of minimal luminal diameter as a simplified measure to detect or exclude low Qa (<600 mL/min). RESULTS:: A total of 81 Doppler ultrasound scans were performed. In all, 26 scans demonstrated brachial artery flow <600 mL/min. Simple logistic regression indicated a weak statistical relationship between the minimal luminal diameter and Qa (R2 = 0.27, p < 0.01). Minimal luminal diameter performed poorly as a marker of low Qa with low specificity, however, showed high negative predictive value for ruling out low Qa at a minimal luminal diameter of 3.2 mm or higher (94%). Qa estimated by brachial artery flow correlated well with Qa estimated by indicator dilution (R2 = 0.83, p < 0.01) without significant mean difference or proportional bias. CONCLUSION:: Minimal luminal diameter correlates weakly with Qa. Low minimal luminal diameter values should not be used in isolation to determine low Qa for a radiocephalic arteriovenous fistula. Conversely, minimal luminal diameter >3.2 mm largely excludes a low-flow radiocephalic arteriovenous fistula in this cohort. Brachial artery flow is a reasonable measure of Qa in comparison with indicator dilution. PMID- 29577803 TI - Corrigendum.

Aberrant interactions of peripheral measures and neurometabolites with lipids in complex regional pain syndrome using magnetic resonance spectroscopy: A pilot study. Mol Pain 2018; 14: doi: 10.1177/1744806917751323 In this article, the authors inadvertently changed the name of the Lip dependents and forgot to mention the usage of the findings.

Lip09-dependent right thalamus and Lip13a-dependent left thalamus may be important to elucidate abnormal interactions between lipids in the central thalamus and peripheral measures in CRPS patients, suggestive of unique mechanisms underlying lipidassociated pathophysiology in CRPS, These findings may be used to develop personalized therapies according to the dominant side of the thalamus (right versus left) and the presence and interactions of specific metabolites. PMID- 29577804 TI - Inflectional Morphology in Fluent Aphasia: A Case Study in a Highly Inflected Language. AB - Inflectional morphology difficulties are typically reported in non-fluent aphasia with agrammatism, but a growing number of studies show that they can also be present in fluent aphasia. In agrammatism, morphological difficulties are conceived as the consequence of impaired phonological encoding and would affect regular verbs more than irregular verbs. However, studies show that inflectional morphology difficulties concern both regular and irregular verbs, and that their origin could be more conceptual/semantic in nature. Additionally, studies report more pronounced impairments for the processing of the past tense compared to other tenses. The goal of this study was to characterize the impairment of inflectional morphology in fluent aphasia. RY, a 69-year-old man with chronic fluent aphasia completed a short neuropsychological and language battery and three experimental tasks of inflectional morphology. The tasks assessed the capacity to select the correct inflected form of a verb based on time information, to access the time information included in an inflectional morpheme, and to produce verbs with tense inflection. His performance was compared to a group of five adults without language impairments. Results showed that RY had difficulties selecting the correct inflected form of a verb, accessing time information transmitted by inflectional morphemes, and producing inflected verbs. His difficulties affected both regular and irregular verbs, and verbs in the present, past, and future tenses. The performance also shows the influence of processing limitations over the production and comprehension of inflectional morphology. More studies of inflectional morphology in fluent aphasia are needed to understand the origin of difficulties. PMID- 29577806 TI - Corrigendum. AB - Callesen J, Richter C, Kristensen C, et al.

AB - We investigated the influence of grapheme familiarity and native language grapheme-phoneme correspondences during second language lexical learning. Native English speakers learned Russian-like words via auditory presentations containing only familiar first language phones, pictured meanings, and exposure to either Cyrillic orthographic forms (Orthography condition) or the sequence (No Orthography condition). Orthography participants saw three types of written forms: familiar-congruent (e.g., -[kom]), familiar-incongruent (e.g., [ralphat]), and unfamiliar (e.g., -[fil]). At test, participants determined whether pictures and words matched according to what they saw during word learning. All participants performed near ceiling in all stimulus conditions, except for Orthography participants on words containing incongruent grapheme phoneme correspondences. These results suggest that first language grapheme phoneme correspondences can cause interference during second language phono lexical acquisition. In addition, these results suggest that orthographic input effects are robust enough to interfere even when the input does not contain novel phones.

AB - Nonresponsiveness to age-related macular degeneration (AMD) treatments has become a growing concern in ophthalmology. Disparity among publications that have assessed pharmacogenetic (PGx) connections between AMD disease genes and treatments has delayed the implementation of PGx testing in AMD. We assessed all AMD PGx publications to identify the degree of agreement for publications within similar ethnic cohorts and worldwide, and the causes for differences in study outcomes. There are no accepted genotype-phenotype correlations, either within similar ethnic cohorts or worldwide. The diversity of measured outcomes, treatment protocols and statistical methods used may be causing this discrepancy. A universally accepted treatment protocol and the creation of agreed response group classification may bridge the gap between AMD PGx publications.

AB - Elevated creatine kinase is a useful screening test in the diagnostic workup of patients with neuromuscular disorders. We did a retrospective study of children with hyperCKemia (>175 IU/L) who were followed in the neuromuscular program of a tertiary care pediatric center from 2005 to 2016. Patients with hyperCKemia were divided into 2 groups: myopathic and nonmyopathic. Within the myopathic group, there were 3 arbitrary subgroups based on creatine kinase values: A (creatine kinase >10 times normal), B (creatine kinase 5-10 times normal), and C (creatine kinase 1-5 times normal). The 3 major categories of myopathies across all the subgroups were muscular dystrophies (commonest) followed by metabolic myopathies and inflammatory myopathies. Among the nonmyopathic causes of hyperCKemia, spinal muscular atrophy was the commonest. Muscular dystrophies should be considered in children with hyperCKemia, muscle weakness, or calf hypertrophy, and metabolic myopathies to be considered in children with recurrent rhabdomyolysis.

AB - Endothelial small and intermediate-conductance, Ca2+-activated K+ channels (KCa2.3 and KCa3.1, respectively) play an important role in the regulation of vascular function and systemic blood pressure. Growing evidence indicates that they are intimately involved in agonist-evoked vasodilation of small resistance arteries throughout the circulation. Small molecule activators of KCa2.x and 3.1 channels, such as SKA-31, can acutely inhibit myogenic tone in isolated resistance arteries, induce effective vasodilation in intact vascular beds, such as the coronary circulation, and acutely decrease systemic blood pressure in vivo. The blood pressure-lowering effect of SKA-31, and early indications of improvement in endothelial dysfunction suggest that endothelial KCa channel activators could eventually be developed into a new class of endothelial targeted agents to combat hypertension or atherosclerosis. This review summarises recent insights into the activation of endothelial Ca2+ activated K+ channels in various vascular beds, and how tools, such as SKA-31, may be beneficial in disease related conditions.

AB - This study aimed (1) to describe and compare scapular kinematics between three groups of swimmers of different levels and a group of non-swimmers, and (2) to assess whether swimming practice alters the asymmetries in scapular kinematics between the dominant and non-dominant sides, both during unilateral arm raising and lowering in the scapular plane. Scapular kinematics were assessed bilaterally during arm raising and lowering in the scapular plane using an electromagnetic system in 42 healthy males, which were split into four groups: control (n = 11), adolescent elite swimmers (n = 11), adult elite swimmers (n = 10), and club-level adult swimmers (n = 10). One-Way ANOVA SPM(t) on two repeated measures showed that the three groups of swimmers had more protracted shoulder between 30 degrees and 90 degrees of arm raising and lowering (p < .001). The three groups of swimmers presented no bilateral difference in scapular upward rotation, while the dominant scapula was more upwardly rotated than the non-dominant one between 74 degrees and 104 degrees of arm elevation in the control group (p < .001). The scapula of adult elite swimmers was more internally rotated between 67 degrees and 116 degrees of humeral elevation during arm raising, and between 81 degrees and 54 degrees during arm lowering in comparison to the other swimming and control groups (p <= .02), who presented similar scapular positioning in internal rotation. In conclusion, the findings of the study pointed out that swimming practice generated protracted shoulders and removed bilateral differences in scapular upward rotation during scaption, while accumulation of swimming practice at elite level enlarged scapular internal rotation. PMID- 29577814 TI - A Two-Step Markov Processes Approach for Parameterization of Cancer State Transition Models for Low- and Middle-Income Countries. AB - Implementation of organized cancer screening and prevention programs in high income countries (HICs) has considerably decreased cancer-related incidence and mortality. In low- and middle-income countries (LMICs), screening and early diagnosis programs are generally unavailable, and most cancers are diagnosed in late stages when survival is very low. Analyzing the cost-effectiveness of alternative cancer control programs and estimating resource needs will help prioritize interventions in LMICs. However, mathematical models of natural cancer onset and progression needed to conduct the economic analyses are predominantly based on populations in HICs because the longitudinal data on screening and diagnoses required for parameterization are unavailable in LMICs. Models currently used for LMICs mostly concentrate on directly calculating the shift in distribution of cancer diagnosis as an evaluative measure of screening. We present a mathematical methodology for the parameterization of natural cancer onset and progression, specifically for LMICs that do not have longitudinal data. This full onset and progression model can help conduct comprehensive analyses of cancer control programs, including cancer screening, by considering both the positive impact of screening as well as any adverse consequences, such as over diagnosis and false-positive results. The methodology has been applied to breast, cervical, and colorectal cancers for 2 regions, under the World Health Organization categorization: Eastern Sub-Saharan Africa (AFRE) and Southeast Asia (SEARB). The cancer models have been incorporated into the Spectrum software and interfaced with country-specific demographic data through the demographic projections (DemProj) module and costing data through the OneHealth tool. These software are open-access and can be used by stakeholders to analyze screening strategies specific to their country of interest. PMID- 29577815 TI - The efficacy of drug-eluting stent for recurrent central venous restenosis in a patient undergoing hemodialysis. AB - INTRODUCTION: Recurrent central venous restenosis is problematic in patients with ipsilateral arteriovenous fistula. We report our experience using a drug-eluting stent for the treatment of recurrent central vein restenosis. CASE REPORT: A 60 year-old man consulted our hospital because of recurrent swelling of his left upper limb with radial-cephalic arteriovenous fistula that originated in the distal forearm. More than 3 years prior, two bare-metal stents were placed for the obstructed lesions in the left subclavian and brachiocephalic venous lesions, and repeated balloon angioplasty for recurrent in-stent stenosis was performed approximately every 3 months. Angiography with iodinated contrast agents revealed an approximately 3-cm-long restenosis at the distal part of the bare-metal stents. One drug-eluting stent (Zilver PTX Drug-Eluting Peripheral Stent; Cook Medical, Bloomington, IN, USA) was deployed at the narrowing lesion, followed by balloon angioplasty. The stenotic lesion was successfully and safely dilated. The patient consulted our hospital 5.5 months after drug-eluting stent placement because of restenosis at the distal part of the drug-eluting stent, but only in a shorter segment than before. Freedom from clinically driven target-lesion revascularization (TLR) extended from 3.1 to 5.5 months after drug-eluting stent placement. Although additional implantation of the second drug-eluting stent was required 14.6 months after the first drug-eluting stent placement, freedom from TLR before/after the second drug-eluting stent placement extended from 4.4 months to more than 8.6 months. CONCLUSION: Drug-eluting stent placement is an effective strategy for recurrent central venous stenosis in patients with ipsilateral arteriovenous fistula. To our knowledge, this is the first report of drug-eluting stent placement for recurrent venous stenosis in a patient undergoing hemodialysis. PMID- 29577816 TI - CDE Pharmacists in the United States. AB - Purpose The purpose of the study was to identify current practice settings for Certified Diabetes Educators (CDEs) who are pharmacists. Following nurses and dietitians, pharmacists are the third largest group of health professionals who hold the CDE credential. The growing number of CDE pharmacists highlights the increasing involvement of pharmacists in diabetes care. What remains unknown is the specific settings in which pharmacist CDEs practice. Methods A cross sectional, nationwide electronic survey was sent to all CDE pharmacists in the United States. Questions regarding demographics, practice setting characteristics, certification information, and common diabetes-related counseling topics were asked of all respondents. Survey items also sought to determine pharmacists' perceptions of the benefits and barriers to obtaining the CDE credential. The questions were dichotomous, Likert-scale response, or open ended. Results A total of 462 survey responses were included in the analysis for a response rate of (462/1275) 36.2%. Respondents identified hospital or health system as the most common practice setting (n = 311), followed by academia (n = 100), community (n = 81), managed care (n = 44), and other settings. Conclusions Study findings provide important data that describe where CDE pharmacists are practicing to provide diabetes education. The continued steady growth of CDE pharmacists suggests a consistent increase of pharmacists practicing diabetes education. Diabetes educators should recognize that CDE pharmacists practice in a variety of different settings.

AB - Composite materials from PET and red mud (RM) wastes were used as catalysts for environmental application such as the wastewater treatment. The PET-RM catalysts were obtained by a mechanical mixture of the residues followed by thermal treatment under an N2 atmosphere (300 degrees C/1 h). An additional activation of the composites with CO2 was investigated (at 800-900 degrees C) to reduce the red mud basicity. The CO2 activation affected the composites surface area and reduced their carbon content. XRD revealed that the haematite (alpha-Fe2O3) and maghemite/magnetite are the main iron oxides present in the composites. Mossbauer characterization indicated the formation of reduced iron species (Fe2+), highly reactive, after the composites heat treatment. The materials were very active catalysts for methylene blue (MB) and paracetamol (PRC) removal from aqueous solution. The catalytic activity revealed to be dependent on the surface area and mainly of the presence of reduced iron species in the catalysts. The MB removal reached 97% for both PET-RM 800/2 h and PET-RM 800/5 h, after 1 h of reaction. In the case of PRC, the highest removal was also obtained for PET-RM 800/2 h and PET RM 800/5 h, of ~25% and 40%, respectively. The contaminants removal mechanism likely occurred through combined adsorption and Fenton-like oxidation processes. PMID- 29577818 TI - Vietnamese American Women's Beliefs and Perceptions About Breast Cancer and Breast Cancer Screening: A Community-Based Participatory Study. AB - INTRODUCTION: Although breast cancer (BC) rates are declining in White non Hispanic American women, they are increasing among Vietnamese American women (VAW) at 1.2% (95% confidence interval [0.1, 2.2]) per year. BC screening rates (64%) are below the national rates (81.1%). This article explores VAW's beliefs about BC and screening. METHOD: Using community-based participatory qualitative descriptive methods, 40 VAW were recruited from Oregon, and four focus groups were conducted. A directed content analysis was used. RESULTS: Main themes were as follows: deferred to a health care provider or relying on self-detection and symptoms; fear of BC versus fear of procedural pain; limited knowledge; motivation by observing others' journey in BC death or survivorship; body image concern; "living carefree," "good fortune-having good health"; and coverage for a mammogram expense means health care access. DISCUSSION: Tailored interventions should address mammogram knowledge, fear, erroneous information, body image, fate and luck, and promoting access. PMID- 29577819 TI - Comparison of the efficacy of parenteral and oral treatment for nutritional vitamin B12 deficiency in children. AB - OBJECTIVE: Although, oral replacement for vitamin B12 deficiency has been proved to be effective in adults, it is mainly treated with parenteral therapy. There are only few studies on oral replacement therapy of vitamin B12 with children. Therefore, we aimed to compare the efficacy of oral treatment with intramuscular vitamin B12 injections in pediatric population. METHODS: Children with serum cobalamin concentrations less than 300 pg/mL, were treated either with the parenteral therapy or with oral vitamin B12. The primary and secondary outcomes of the study were the normalization of serum vitamin B12 and hemoglobin at first month, respectively. RESULTS: Post-treatment vitamin B12 values were significantly higher than pre-treatment values (p-value <.001). Vitamin B12 increased from 183.5 +/- 47 pg/mL to 482 +/- 318.9 pg/mL in the oral and from 175.5 +/- 42.5 pg/mL to 838 +/- 547 pg/mL in the parenteral treatment arm (p value <.001). Before treatment, 82 children had anemia according to age and gender. After treatment, 14/41 and 8/41 patients still had anemia at the first month of treatment in the parenteral and oral arms, respectively. The number of patients who still have anemia at the end of the 1st month of treatment did not significantly changed in the parenteral and oral treatment groups (p-value = .44). CONCLUSIONS: In this study, both oral and parenteral formulations were shown to be effective in normalizing vitamin B12 levels. We suggest that oral formulations may be considered to be safe as a first line treatment for vitamin B12 deficiency in children. PMID- 29577820 TI - Risk factor profile in patients with stroke at a young age. AB - Background The distribution of risk factors for stroke is related to gender and age. The main objective of study was to determine the type and frequency of stroke risk factors in patients with first-in-life stroke before the age of 50. Methods Our study included patients under the age of 50 with first-in-life stroke. The following data obtained from all participants were analyzed: a neuroimaging of the head, wide panel of blood tests, electrocardiogram, transesophageal echocardiography, ultrasound of the carotid/cerebral arteries. 24 hour ECG monitoring and angio-MRI of head were performed in most patients. Results One hundred and eighty-four patients were qualified into the study; mean age - 39 years (female 45%). The female gender was significantly more often associated with diabetes, carotid/cerebral artery stenosis, myocardial infarction, cardiomyopathy and risk factors associated with lifestyle. More than half of the patients presented at least two risk stroke factors. The most frequent categories of risk factors were related to arteries and metabolic diseases. Vascular risk factors were among the most frequent in individual age categories. Hereditary stroke-burden was significant in the patient before the age of 20.15% of the patients haven't got known stroke risk factor. Conclusions Angiopathy is the most common risk factor for stroke at a young age. More than half of the patients with stroke at a young age have at least two independent risk factors for stroke. In the first two decades of life, the most frequent risk factors for stroke are heart diseases; arterial diseases play a dominant role in the consecutive three decades. PMID- 29577821 TI - A patient's view on the location of the temporomandibular joint. AB - Objective A survey was held to establish whether laypeople knew the location of their temporomandibular joint. Methods A sample of 61 participants, visiting their dental office for a routine check-up, was given a three-question survey of whether they knew the location of their temporomandibular joint and could point to this location. Results Thirty-eight participants answered the question affirmatively. Only 13 pointed to the correct location. Of these, six participants received consultation for TMD in the past, three participants were healthcare providers, and four participants actually had knowledge of the exact location. Out of 23 participants who did not know the location, one accidently designated the correct position. Conclusion The location of the temporomandibular joint is not a well-known site for many patients. In the presence of orofacial pain, it seems advisable to let the patient designate and record the site of the pain on a drawing on the patient chart. PMID- 29577822 TI - Psychocardiological disorder and brain serotonin after comorbid myocardial infarction and depression: an experimental study. AB - Objectives We investigated whether trimetazidine pretreatment can regulate central and peripheral serotonin (5-HT) in rats of myocardial infarction (MI) combined with depression. Methods Forty rats were randomly assigned to a sham operation group (n = 10) and a disease model group (n = 30). The sham operation group was pretreated with normal saline for 4 weeks. The disease model group was randomly assigned further into a negative control subgroup, a positive control subgroup, and a treatment subgroup - the groups received saline, sertraline, and trimetazidine pretreatment, respectively, for 4 weeks, then the rats were subjected to MI combined with depression. 5-HT concentrations in the serum, platelet lysate, and cerebral cortex lysate were analyzed with ELISA. Results The levels of serum 5-HT and platelet 5-HT were significantly lower in negative control subgroup than the sham operation group (P < 0.05), but there was no significant difference in brain 5-HT (P > 0.05). Compared with the negative control subgroup, the levels of serum 5-HT and platelet 5-HT in the positive control subgroup and treatment subgroup were significantly higher (P < 0.05). The levels of 5-HT in brain of the positive control subgroup and treatment subgroup were significantly lower than those in the negative control subgroup (P < 0.05). Conclusions Trimetazidine pretreatment can increase serum and platelet 5-HT levels in rats with MI and depression and decrease 5-HT levels in brain tissue. This regulatory effect on central and peripheral 5-HT suggests a role for trimetazidine in the treatment of psychocardiological diseases. PMID- 29577823 TI - Testing the Predictive Validity of the Hendrich II Fall Risk Model. AB - Cumulative data on patient fall risk have been compiled in electronic medical records systems, and it is possible to test the validity of fall-risk assessment tools using these data between the times of admission and occurrence of a fall. The Hendrich II Fall Risk Model scores assessed during three time points of hospital stays were extracted and used for testing the predictive validity: (a) upon admission, (b) when the maximum fall-risk score from admission to falling or discharge, and (c) immediately before falling or discharge. Predictive validity was examined using seven predictive indicators. In addition, logistic regression analysis was used to identify factors that significantly affect the occurrence of a fall. Among the different time points, the maximum fall-risk score assessed between admission and falling or discharge showed the best predictive performance. Confusion or disorientation and having a poor ability to rise from a sitting position were significant risk factors for a fall. PMID- 29577824 TI - Cavitating Leukoencephalopathy With Posterior Predominance Caused by a Deletion in the APOPT1 Gene in an Indian Boy. AB - A 5-year-old Indian boy presented with subacute onset regression of milestones associated with seizures and spasticity. The symptoms started after an attack of measles. The magnetic resonance imaging (MRI) of the brain showed cavitating leukodystrophy with posterior predominance. Molecular analysis of the APOPT1 gene, a recently described gene associated with mitochondrial leukodystrophy, showed the patient to be homozygous for a 12.82-kilobase deletion, including coding exon 3. Deletion of exon 3 produces a frameshift, predicting the translation of a truncated protein (p.Glu121Valfs*4). The patient was started on mitochondrial cocktail regimen of thiamine, riboflavin, coenzyme Q and carnitine. Although he initially showed some improvement, he died 6 months after the onset of his illness. PMID- 29577825 TI - Trajectories of positive aspects of caregiving among family caregivers of stroke survivors: the differential impact of stroke-survivor disability. AB - Objective To delineate positive aspects of caregiving trajectories among family caregivers of stroke-survivors and determine the impact of stroke-survivor disability, a time-varying factor, on the delineated trajectories. Methods In a longitudinal study, family caregivers of 173 stroke-survivors in Singapore were administered the Positive Aspects of Caregiving scale (PAC scale) thrice (baseline/3 months/6 months). Group-based trajectory modeling delineated positive aspects of caregiving trajectories and identified the impact of stroke-survivor disability on the trajectories. Results Two distinct positive aspects of caregiving trajectories, Persistently Low and Persistently High were delineated. Increase in stroke-survivor disability was associated with a significant downward shift (reduction in positive aspects of caregiving) of the Persistently Low trajectory and a significant upward shift (increase in positive aspects of caregiving) of the Persistently High trajectory. Older caregivers were more likely to follow the Persistently High trajectory. Conclusions Care professionals should be mindful of the heterogeneity in the longitudinal pattern of positive feelings resulting from care provision among family caregivers of stroke survivors, and the differential impact of stroke-survivor disability on the pattern of positive feelings. Younger caregivers as well as family caregivers who have low positive feelings at the start of their caregiver journey and experience worsening functional disability of their care recipient (stroke-survivor) require greater attention and support. PMID- 29577826 TI - Pain, Fear of Falling, and Functional Performance Among Nursing Home Residents: A Longitudinal Study. AB - The aim of this study was to analyze the impact of being pain-affected and fear of falling on functional performance among nursing home residents, longitudinally. We used 6-month follow-up data from a cluster-randomized trial of 12 nursing homes (cluster level) with 239 nursing home residents at baseline (mean age, 95% confidence interval [CI] = 83.04 [81.40, 84.69], 70% women). The longitudinal analysis provided data on pain, fear of falling, functional mobility, and activities of daily living (individual level). The data revealed a trend indicating that pain-relieved nursing home residents showed better functional mobility over time. The results on fear of falling demonstrate obvious differences in the functional performance of nursing home residents cross sectionally but not longitudinally. Nevertheless, the results underline the importance of an effective pain treatment to prevent decline in functional mobility among nursing home residents. Further longitudinal surveys are needed to verify the findings on functional performance. PMID- 29577827 TI - The transfer of strength and power into the stroke biomechanics of young swimmers over a 34-week period. AB - The purpose of this study was to learn the interplay between dry-land strength and conditioning, and stroke biomechanics in young swimmers, during a 34-week training programme. Twenty-seven swimmers (overall: 13.33 +/- 0.85 years old; 11 boys: 13.5 +/- 0.75 years old; 16 girls: 13.2 +/- 0.92 years old) competing at regional- and national-level competitions were evaluated. The swimmers were submitted to a specific in-water and dry-land strength training over 34 weeks (and evaluated at three time points: pre-, mid-, and post-test; M1, M2, and M3, respectively). The 100-m freestyle performance was chosen as the main outcome (i.e. dependent variable). The arm span (AS; anthropometrics), throwing velocity (TV; strength), stroke length (SL), and stroke frequency (SF; kinematics) were selected as independent variables. There was a performance enhancement over time (M1 vs. M3: 68.72 +/- 5.57 s, 66.23 +/- 5.23 s; Delta = -3.77%; 95% CI: -3.98; 3.56) and an overall improvement of the remaining variables. At M1 and M2, all links between variables presented significant effects (p < .001), except the TV SL and the TV-SF path. At M3, all links between variables presented significant effects (p <= .05). Between M1 and M3, the direct effect of the TV to the stroke biomechanics parameters (SL and SF) increased. The model predicted 89%, 88%, and 92% of the performance at M1, M2, and M3, respectively, with a reasonable adjustment (i.e. goodness-of-fit M1: chi2/df = 3.82; M2: chi2/df = 3.08; M3: chi2/df = 4.94). These findings show that strength and conditioning parameters have a direct effect on the stroke biomechanics, and the latter one on the swimming performance. PMID- 29577828 TI - Restless legs syndrome in Multiple Sclerosis patients: a contributing factor for fatigue, impaired functional capacity, and diminished health-related quality of life. AB - Objectives Restless legs syndrome (RLS) symptoms are common in Multiple Sclerosis (MS) patients. The aim of the current study was to examine for the first time whether RLS could affect the functional capacity and various contributing parameters related to quality of life and fatigue in MS patients. Methods According to their RLS status, 50 relapsing-remitting MS patients were divided into the RLS (n = 10) and non-RLS groups (n = 40). Specific questionnaires were used in order to assess the health-related quality of life (HRQoL), fatigue levels, sleep quality, daily sleepiness, and depression symptoms of the patients. Functional capacity was examined using a battery of functional tests. Total body and visceral fat levels were assessed via bioelectrical impedance analyzers. Results Sleep quality, depression, fatigue, and HRQoL levels were found to be significantly worse in the patients with RLS compared to their free-RLS counterparts (P < 0.05). In addition, patients with RLS were found to exhibit further impairments in their performance in various functional tests related mainly with strength levels of lower extremities (P < 0.05). Finally, the patients with RLS were found to have significantly higher both total and trunk fat levels compared to patients without RLS (P < 0.05). A strong correlation was observed between the severity of RLS symptoms, sleep quality, fatigue, and QoL levels. Discussion It seems that RLS contributes even further to impairments on sleep quality, fatigue, functional capacity, and therefore HRQoL levels in relapsing-remitting MS patients, whilst for the first time a link between high fat levels has been revealed. PMID- 29577829 TI - Single-Docking Full Robotic Surgery for Rectal Cancer: A Single-Center Experience. AB - PURPOSE: Robotic surgery has gradually gained importance in the treatment of rectal cancer. However, recent studies have not shown any advantages when compared with laparoscopy. The objective of this study is to report a single surgeon's experience in robotic rectal surgery focusing on short-term and long term outcomes. METHODS: Sixty consecutive robotic rectal resections for adenocarcinoma, over a 4-year period, were retrospectively reviewed. Patients' characteristics and perioperative outcomes were analyzed. Oncological outcomes and surgical resection quality as well as overall and disease-free survival were also assessed. RESULTS: Thirty patients out of 60 (50%) underwent neoadjuvant therapy. Anterior rectal resection was performed in 52 cases (86.7%), and abdominoperineal resection was done in 8 cases (13.3%). Mean operative time was 283 (+/-68.6) minutes. The conversion rate was 5% (3 patients). Postoperative complications occurred in 10 cases (16.7%), and reoperation was required in 1 case (1.7%). Mean hospital stay was 9 days, while 30-day mortality was 1.7% (1 patients). The histopathological analysis reported a negative circumferential radial margin and distal margins in 100% of cases with a complete or near complete total mesorectal excision in 98.3% of patients. Mean follow-up was 32.8 months with a recurrence rate of 3.4% (2 patients). Overall survival and disease free survival were 94% and 87%, respectively. CONCLUSIONS: Robotic surgery for rectal cancer proves to be safe and feasible when performed by highly skilled surgeons. It offers acceptable perioperative outcomes with a conversion rate notably lower than with the laparoscopic approach. Adequate pathological results and long-term oncological outcomes were also obtained. PMID- 29577830 TI - Robotic Colorectal Resection With and Without the Use of the New Da Vinci Table Motion: A Case-Matched Study. AB - BACKGROUND: The da Vinci Table Motion (dVTM) is a new device that enables patients to be repositioned with instruments in place within the abdomen, and without undocking the robot. The present study was designed to compare operative and short-term outcomes of patients undergoing colorectal cancer surgery with the da Vinci Xi system, with or without use of the dVTM. METHODS: Ten patients underwent robotic colorectal resection for cancer with the use of dVTM (Xi-dVTM group) between May 2015 and October 2015 at our center. The intraoperative and short-term clinical outcome were compared, using a case-control methodology (propensity scores approach to create 1:2 matched pairs), with a similar group of patients who underwent robotic colorectal surgery for cancer without the use of the dVTM device (Xi-only group). RESULTS: Overall robotic operative time was shorter in the Xi-dVTM group ( P = .04). Operations were executed fully robotic in all Xi-dVTM cases, while 2 cases of the Xi-only group required conversion to open surgery because of bulky tumors and difficult exposure. Postoperative medical complications were higher in the Xi-only group ( P = .024). CONCLUSIONS: In this preliminary experience, the use of the new dVTM with the da Vinci Xi in colorectal surgery, by overcoming the limitations of the fixed positions of the patient, enhanced the workflow and resulted in improved exposure of the operative field. Further studies with a greater number of patients are needed to confirm these benefits of the dVTM-da Vinci Xi robotically assisted colorectal surgery. PMID- 29577831 TI - The Use of Barbed Suture for Intracorporeal Mechanical Anastomosis During a Totally Laparoscopic Right Colectomy: Is It Safe? A Retrospective Nonrandomized Comparative Multicenter Study. AB - BACKGROUND: A totally laparoscopic right colectomy could be perceived as a more challenging procedure over a laparoscopic-assisted right colectomy owing to the difficulty of intracorporeal anastomosis and the closure of the enterotomy. The aim of this study is to evaluate the safety and efficacy of the barbed auto locking absorbable suture for the closure of an anastomotic stapler-access enterotomy during a totally laparoscopic right colectomy. METHODS: From January 2010 to April 2016, data from patients who had undergone a laparoscopic right colectomy in 2 different departments of 2 institutions (the Department of General and Minimally Invasive Surgery, San Camillo Hospital in Trento and the Department of Surgical Specialties and Nephrology, University Federico II in Naples) were retrospectively analyzed. We compared the data of patients in whom the stapler access enterotomy was closed through a conventional absorbable suture (Group A), with the data of patients in whom a stapler-access enterotomy was closed through a V-Loc 180 suture (Group B). Biometric features and intraoperative and postoperative data were collected and analyzed. RESULTS: The 2 groups (Group A: 40 patients; Group B: 40 patients) were comparable for biometric features and postoperative outcomes. The anastomosing time was lower in Group B. A statistically significant difference was noted in the mean operative time between Groups A and B (Group A = 134.92 +/- 34.17; Group B = 120.92 +/- 23.27, P = .035). Only one anastomotic leakage per group was recorded, each treated with an anastomosis redo. During the reoperations, we find in both groups an intact stapler-access enterotomy. CONCLUSION: On retrospective analysis, barbed suture appears to be safe and efficient for closure of the stapler-access enterotomy during totally laparoscopic right colectomy. PMID- 29577832 TI - The Need for Accurate Records. AB - Dear AfPP I have recently obtained a senior post in a hospital that is in a different part of the UK in relation to where I have always worked. I have become aware of differing practices, many of which are improving patient care. However, I am concerned that in this perioperative environment, there is no permanent record of items used during each case. The only records of the items used in any one case are those that are recorded on the swab board and the signatures of the staff who undertake the final count in the theatre register. In some of my previous jobs, we have recorded the count on a separate sheet that was then filed in the patients' notes by the scrub practitioner of the case, thus providing a permanent record of the count in the patients' notes. Can AfPP advise on whether a record in the patients' notes is necessary? Concerned from County Armagh. PMID- 29577834 TI - "Do You Want to Go Forward or Do You Want to Go Under?" Men's Mental Health in and Out of Prison. AB - More than 11 million people are currently imprisoned worldwide, with the vast majority of incarcerated individuals being male. Hypermasculine environments in prison are often tied to men's health risks, and gathering information about mental health is fundamental to improving prison as well as community services. The purpose of the current study was to describe the connections between masculinities and men's mental health among prisoners transitioning into and out of a Canadian federal correctional facility. Two focus groups were conducted with a total of 18 men who had recently been released from a federal correctional facility. The focus group interviews were analyzed to inductively derive patterns pertaining to men's mental health challenges and resiliencies "on the inside" and "on the outside." Participant's challenges in prison related to heightened stresses associated with being incarcerated and the negative impact on preexisting mental illness including imposed changes to treatment regimens. Men's resiliencies included relinquishing aggression and connecting to learn from other men "on the inside." Mental health challenges "on the outside" included a lack of work skills and finances which increased the barriers that many men experienced when trying to access community-based mental health services. Mental health resiliencies employed by participants "on the outside" included self-monitoring and management to reduce negative thoughts, avoiding substance use and attaining adequate exercise and sleep. The current study findings offer practice and policy guidance to advance the well-being of this vulnerable subgroup of men in as well as out of prison. PMID- 29577833 TI - Association Between Nonalcoholic Fatty Liver Disease and Severe Male Reproductive Organ Impairment (Germinal Epithelial Loss): Study on a Mouse Model and on Human Patients. AB - Metabolic syndrome (MS) has been associated with testicular damage. Nonalcoholic fatty liver disease (NAFLD) is a multisystemic disease that affects different organs, but its effect on the testes is unknown. A study analyzing germ cell involvement on BALB/c mice was carried out. A parallel comparative study was conducted that investigated alterations in the germinal epithelium of male humans that died from an unrelated acute event. The complete medical histories and histologic samples of the thoracic aorta, liver tissue, and testicular tissue from the deceased subjects were collected. The degree of germinal epithelial loss (DGEL) was evaluated and the clinical and histologic data were compared between individuals with and without NAFLD. The only metabolic or morphologic variable that caused a significant difference in the DGEL, in both the animal model and humans, was the presence of liver steatosis. The percentage of steatosis was also correlated with the percentage of the DGEL. In humans, steatosis (greater than 20%) increased the risk 12-fold for presenting with a severe DGEL (OR: 12.5; 95% CI [1.2, 128.9]; p = .03). There was no association with age above 50 years or MS components. Steatosis grade was also correlated with atherosclerosis grade. NAFLD was a strongly associated factor implicated in severe DGEL, as well as the testis was identified as a probable target organ for damage caused by the disease. This finding could result in the search for new approach strategies in the management of men with fertility problems. Further studies are required to confirm these results. PMID- 29577835 TI - Hispanic Young Males' Mental Health From Adolescence Through the Transition to Fatherhood. AB - The objective of the current study was to examine the associations between the transition to fatherhood and depressive symptoms scores among Hispanic men. Using the sample of Hispanic men included in the National Longitudinal Study of Adolescent to Adult Health, depressive symptom scores were examined from 1994 to 2008. A "fatherhood-year" data set was created that included the men's Center for Epidemiologic Studies Depression Scale (CES-D) scores as well as residency status with the child. By regressing age-adjusted standardized depressive symptom scores, associations between mental health scores of Hispanic men and their transition to fatherhood were identified. Among the 1,715 Hispanic men, resident ( n = 502) and nonresident ( n = 99) Hispanic fathers reported an increase in depressive symptom scores (CES-D) during the first 5 years after entrance into fatherhood (beta = 0.150, 95% CI [0.062, 0.239] and beta = 0.153, 95% CI [0.034, 0.271], respectively) compared to non-fathers ( n = 1,114), representing an increase of 10% for resident fathers and a 15% for nonresident fathers. Hispanic non-fathers reported a decrease in depressive symptom scores (CES-D) during parallel ages. Hispanic fathers, regardless of residency status, reported increased depressive symptoms in the first 5 years after the transition into fatherhood, a period critical in child development. PMID- 29577836 TI - "Boy Crisis" or "Girl Risk"? The Gender Difference in Nonsuicidal Self-Injurious Behavior Among Middle-School Students in China and its Relationship to Gender Role Conflict and Violent Experiences. AB - PURPOSE: We attempted to test if there were gender differences in nonsuicidal self-injurious (NSSI) behaviors among Chinese middle-school students, and analyze the impact of gender role conflict and violent experiences on these behaviors among middle-school students of different genders. METHOD: Based on the survey data from seven middle schools in Xi'an region of China, the gender difference in NSSI behaviors and its associated factors were analyzed in this study. RESULTS: There was no significant gender difference in NSSI behaviors among middle-school students; however, female middle-school students were more likely to experience gender role conflicts while male students were more likely to experience all kinds of violence earlier. Gender role conflicts and violent experiences can explain the prevalence of NSSI behaviors by gender, to some extent. CONCLUSIONS: The hypothesis on gender patterns of "boy crisis" or "girl risk" on NSSI prevalence was not verified; however, a "girl risk" for gender role conflicts and a "boy crisis" in violent experiences were found. The gender role conflicts were significantly associated with NSSI prevalence among middle-school students to some extent; however, this relationship was adjusted by variables of violent experiences. The different variables of violent experiences were the important predictors of NSSI prevalence among male and female middle-school students with specific contents varying across genders. PMID- 29577837 TI - 2016 Survey of State-Level Health Resources for Men and Boys: Identification of an Inadvertent and Remediable Service and Health Disparity. AB - This survey evaluated resources available to men and boys at the state level including state public health departments (SPHDs), other state agencies, and governor's offices. Most of the resources and programs are found in the SPHDs and these administer state-initiated and federally funded health programs to provide services and protection to a broad range of populations; however, many men's health advocates believe that SPHDs have failed to create equivalent services for men and boys, inadvertently creating a health disparity. Men's Health Network conducts a survey of state resources, including those found in SPHDs, every 2 years to identify resources available for men and women, determine the extent of any disparity, and establish a relationship with SPHD officials. Data were obtained from all 50 states and Washington, D.C. An analysis of the 2016 survey data indicates that there are few resources allocated and a lack of readily available information on health and preventive care created specifically for men and boys. The data observed that most health information intended for men and boys was scarce among states or oftentimes included on websites that primarily focused on women's health. A potential result of this is a loss of engagement with appropriate health-care providers due to a lack of information. This study continues to validate the disparity between health outcomes for women and men. It continues to highlight the need for better resource allocation, outreach, and health programs specifically tailored to men and boys in order to improve overall community well-being. PMID- 29577838 TI - Effort-Reward Imbalance and Work Productivity Among Hotel Housekeeping Employees: A Pilot Study. AB - This study explored the relationship between effort-reward imbalance (ERI) at work and work productivity among hotel housekeepers. A community-based approach was used to recruit 23 hotel housekeepers who completed the ERI and Work Performance Questionnaires. Work productivity was determined by combining self report absenteeism and presenteeism. More than 40% of the participants reported high ERI (ERI >1). Also, 59.1% reported low work productivity. Interestingly, despite the individualized high reports of ERI and low work productivity, correlation analysis showed that high ERI was correlated with high presenteeism and work productivity as a whole. This is the first study to explore work productivity among this worker group. Despite the small sample size and the cross sectional nature of the study, this study points to the need for organization based interventions to not only improve employee health but also their work productivity. PMID- 29577839 TI - Single-sided deaf tactical unit officer treated with cochlear implantation. AB - OBJECTIVES: To demonstrate the efficacy of cochlear implantation for management of a severe single-sided deaf tactical unit officer. Showing that hearing improvement provided by cochlear implantation was sufficient for him to return to work as a police tactical officer. METHODS: Case report. RESULTS: A 43 years-old man working as a tactical unit officer suffered from a work-related severe single sided hearing loss. He tried unsuccessfully many types of hearing aids including a contralateral routing of sound (CROS) system and a bone conduction hearing aid with a headband. He was finally treated with cochlear implantation which provided enough localization and hearing abilities for a complete return to work as a tactical unit officer. DISCUSSION: This case report demonstrates that cochlear implantation was very successful for a patient suffering from severe single-sided hearing loss. The current literature demonstrates benefits from cochlear implant over CROS and osseointegrated devices in unilateral hearing loss. Nevertheless, literature does not report any case of patient suffering from single-sided deafness that received a cochlear implant and a complete bilateral hearing rehabilitation that allowed him to return to work as a police tactical officer. CONCLUSION: Cochlear implantation was the only effective treatment to provide our patient enough localization and hearing abilities for a complete return to work as a police tactical officer. As no consensus has been established about selection criteria for cochlear implantation in single-sided deafness, we suggest that the patient's occupation should be considered when reviewing his candidacy for cochlear implantation. PMID- 29577840 TI - The Relevance of Victimization Experiences for Predicting the Development of Threat Symptoms During Adolescence and Early Adulthood. AB - The "threat" portion of the threat/control override symptom constellation is characterized by the belief by an individual that others seek to do them harm. There has yet to be an examination of the link between perceived threat symptomatology and the experience of victimization, despite the fact that both constructs are linked to the perpetration of violent behavior. Furthermore, there has yet to be research which examines the heterogeneity in developmental patterns of threat symptomatology. The present research utilized the Pathways to Desistance data to model the developmental heterogeneity in perceived threat symptomatology across adolescence and early adulthood using group-based trajectory modeling. A series of multinomial logistic regression models were then estimated to examine the relevance of victimization experiences for predicting trajectory group assignment. A five-group model of development during adolescence and early adulthood best fit the threat symptom data. Victimization experienced prior to age 16 predicted assignment to all groups in the model characterized by presentation of threat symptoms at some point during the study. Victimization experienced between ages 16 and 23 predicted assignment to the High Chronic group and marginally predicted assignment to the Accelerating group. These results indicate that victimization does indeed predict the presentation of perceived threat symptomatology. This indicates that presentation of threat symptoms may be indicative of a history of victimization. Proper screening of those presenting threat symptoms may help to better orient treatment plans for modalities centered on victimization experiences. Future research should investigate the possibility that threat symptoms mediate the relationship between victimization and violent behavior. PMID- 29577841 TI - Exploring the Potential Campus-Level Impact of Online Universal Sexual Assault Prevention Education. AB - Campus sexual assault is a long-standing challenge and continues to be a severe problem for American higher education. The present study examines the short-term impact of a widely utilized sexual violence prevention course for matriculating college students as a population-level prevention approach. The course focuses on correcting misperceptions of normative behavior, increasing students' likelihood to intervene in disconcerting situations, and encouraging empathy and support for victims. Participants were 167,424 first-year college students from 80 four-year institutions who completed preintervention and postintervention surveys to assess changes in composite factor scores derived from 20 attitudinal, self-efficacy, and behavioral intention items. Employing the composite factor scores as dependent variables, individual ANOVAs were run for each of the institutions to test whether there were significant increases in mean factor scores. High percentages of institutions saw statistically significant increases ( p < .05) in self-reported ability and intention to intervene to prevent sexual assault and relationship violence (98%), empathy and support for victims (84%), and corrected perceptions of social norms (75%). Fewer schools saw significant reductions in endorsement of sexual assault myths (34%). These findings suggest that when implemented as a population-level intervention for all first-year college students, the prevention course can foster accurate perceptions of positive social norms, increase empathy and support for victims, and increase students' stated ability and intention to intervene. PMID- 29577842 TI - Sexual Violence Among College Students Attending a Nonresidential Campus. AB - Using the empirical powers of theories of intersectionality, the study investigates the association between students' demographics (such as gender identity, race, ethnicity, age, and socioeconomic status) and sexual violence victimization. An anonymous survey was employed to collect data from a cluster random sample of 966 students attending face-to-face courses at a midsize urban nonresidential campus. The empirical findings suggest that being older and female are the only statistically significant factors in the analysis. As the first attempt to focus on students attending nonresidential programs in the United States, the study presents implications for policy and program implementation to include issues pertinent to students' diversity to better respond to students' risk of victimization. PMID- 29577843 TI - Contributions to Depressed Affect in Latina Women: Examining the Effectiveness of the Moms' Empowerment Program. AB - Intimate partner violence (IPV) is a significant social and public health problem that includes physical violence, sexual violence, threats of physical or sexual violence, stalking, and psychological aggression by an intimate partner. Estimates suggest that 35% of Latinas living in the United States experience IPV in their lifetime, with known severe negative outcomes. One mental health consequence of concern is depression, which disproportionately affects IPV exposed Latinas. The present study tested the effectiveness of the Moms' Empowerment Program (MEP), a culturally adapted intervention to reduce depressive symptoms among IPV-exposed Spanish-speaking Latina mothers. Additional psychosocial predictors of levels of depressed affect over time are examined, including levels of post-traumatic stress, IPV exposure, positive parenting, parental acceptance of children's negative emotions, and maternal employment. Participants ( N = 72) were assigned to a treatment or a wait-list comparison condition, and those in the treatment group completed a 10-week group intervention addressing the unique problems associated with IPV exposure, mental health, and parenting among Spanish-speaking Latinas. Results of multilevel modeling revealed that participation in the MEP was associated with significant reductions in depressed affect. Lower levels of post-traumatic stress and higher levels of positive parenting, maternal acceptance of children's negative emotions, and maternal employment predicted lower levels of depressed affect. The amount of total IPV exposure was not significantly associated with the extent of depressed affect. The MEP represents a culturally tailored, evidence-based intervention to reduce depressed affect among Spanish-speaking Latinas. The clinical implications of the additional predictors of levels of depressed affect are discussed. PMID- 29577844 TI - Factors Affecting Sexual History Taking in a Health Center Serving Homeless Persons. AB - Low rates of documentation of sexual histories have been reported and research on sexual history taking (SHT) has focused on the content of, barriers to collecting, and interventions to improve documentation of sexual histories. Absent from this literature is an understanding of the contextual factors affecting SHT. To address this gap, a focused ethnography of one health center was conducted. Data were collected through observations of health care encounters and interviews with health care providers (HCPs). No SHT was observed and this was likely influenced by patients' characteristics, communication between patients and HCPs, the prioritization of patients' basic needs, and time constraints imposed upon encounters. Given that the health center studied serves patients experiencing homelessness, behavioral health concerns, and opioid use disorder, findings illuminate areas for future inquiry into a patient population affected by social as well as physiologic determinants of health and potentially at high risk for adverse sexual health outcomes. PMID- 29577845 TI - The Dominant Obesity Discourse Versus Children's Conceptualizations of Health: A Comparison Through Dialogue and Drawings. AB - The emphasis on childhood obesity reduction has been attributed to the dominant obesity discourse. However, some researchers argue that this discourse may be ineffective and even harmful for children. From a post-structuralist perspective, the dominant obesity discourse has the power to shape children's subjectivities, though subjectivities may also be influenced by personal experiences and other knowledge about bodies and health. There is limited research which explores how children's conceptualizations of health are informed by the dominant obesity discourse. To address this knowledge gap, qualitative data were collected from 8- to 11-year-old children ( n = 29) regarding their conceptualizations of health, healthy bodies, and health practices. Results suggest that children's conceptualizations reflected arguments embedded within the dominant obesity discourse, but at times, also contradicted or deviated from it. Study findings can be applied toward children's health promotion programming to offer a more holistic and inclusive perspective on health and well-being. PMID- 29577846 TI - "Like Every Normal Person?!" The Paradoxical Effect of Aging With Schizophrenia. AB - Studies on aging with schizophrenia have focused mainly on the adversities of aging with mental illness. The present study, however, examined the subjective experience of well-being among individuals with schizophrenia. Taking a phenomenological reflective life-world approach, in-depth, semistructured interviews with 18 aging individuals with schizophrenia were thematically analyzed. Four main themes emerged: (a) "I love the pills . . . they are very helpful": A balanced course of the illness as a basis for well-being in old age; (b) "I'm going to have my own exhibition at the museum": Self-fulfillment as promoting well-being; (c) "It's just like a family here": Experiencing a sense of belonging; and (d) "I live like everyone else": Aging as an opportunity for normalization. Alongside hardship, the participants perceived old age as a "window of opportunity," enabling the fulfillment of lifelong desires for a social life, acceptance, and a satisfying occupation. Implications regarding interventions with this unique population are discussed. PMID- 29577847 TI - When Your Pregnancy Echoes Your Illness: Transition to Motherhood With Inflammatory Bowel Disease. AB - Our aim is to provide an understanding of the experience of women with inflammatory bowel disease (IBD) who have made the transition to motherhood. A total of 22 mothers with IBD were recruited from around the United Kingdom. Semi structured interviews were conducted and analyzed using thematic analysis. The central concept- Blurred Lines-offers a novel frame for understanding the transition to motherhood with IBD through identifying parallels between having IBD and becoming, and being, a mother. Parallels clustered into three main themes: Need for Readiness, Lifestyle Changes, and Monitoring Personal and Physical Development. Hence, women with IBD are in some ways well prepared for the challenges of motherhood even though, as a group, they tend to restrict their reproductive choices. We recommend health professionals initiate conversations about reproduction early and provide a multidisciplinary approach to pregnancy and IBD in which women have confidence that their ongoing treatment will be integrated successfully with their maternity care. PMID- 29577848 TI - Survival, Signaling, and Security: Foster Carers' and Residential Carers' Accounts of Self-Harming Practices Among Children and Young People in Care. AB - Research on clinicians' interpretations of self-harming practices has shown that they can often be negative. To date there has been limited consideration of other professionals' narratives, notably those working in social care. This article presents focus group and interview data generated with foster carers ( n = 15) and residential carers ( n = 15) to explore the symbolic meanings ascribed to self-harm among the children and young people they care for. Three repertoires of interpretation are presented: survival, which conceives self-harm as a mechanism for redefining the identity of "looked-after"; signaling, which understands self harm as a communicative tool for the expression of emotion; and security, which sees self-harming practices as testing the authenticity and safety of the caring relationship. Through their focus on sociocultural narratives, carers position themselves as experts on self-harm due to their intimacy with young people's social worlds. This construction potentially creates distance from health professionals, which is problematic given the current privileging of interprofessional working. PMID- 29577849 TI - Facial nerve stimulation after cochlear implantation: Our experience in 448 adult patients. AB - Facial nerve stimulation (FNS) after cochlear implant activation is a well-known side effect, with an incidence rate raging between 1% and 14.9%. Some causes of deafness have been associated with a higher incidence of this entity, however, there is still no consensus regarding its pathophysiological mechanisms. Although FNS can be solved with changes in speech processor programming, in some cases this can lead to a decrease in performance. The aim of this work was to review the epidemiologic, clinical aspects, and performance results in a group of FNS after cochlear implantation. It was conducted a retrospective chart review of 448 adult patients, all implanted between 1985 and 2016. Speech perception tests results were statistically analysed, using non-parametric tests. We registered a group of 13 patients with FNS, contributing to a prevalence of 2.9%. The causes of hearing loss in this group varied between otosclerosis, Meniere's disease, head trauma, and idiopathic cause. Six cases were managed by changing the programming strategy and the other seven required the deactivation of the affected electrodes. Statistical evaluation showed no statistically significant difference between the performance results of the groups with and without FNS. In this series, the overall incidence of FNS was consistent with the literature. Our study supports the current idea that FNS can frequently be eliminated by changing programming strategies or deactivating the involved electrodes, without affecting the implant's performance. PMID- 29577850 TI - A Statistical Approach to Detect Intrinsically Disordered Proteins Associated with Uterine Leiomyoma. AB - BACKGROUND: Uterine Leiomyoma is mainly widespread non-malignant tumor. Around more than 80% woman have these particular tumor among them only 30% of them are detected. Integrin-?1 is one of the up regulated biomarkers during tumorigenesis which is also associated with structural disordered. Intrinsically disordered proteins are one of the types which are dealing with un-structuredness especially in tertiary structural orchestration. Around 30% of the human proteins consist of intrinsically disordered regions. It is obvious that IDPs should have a significant change of functional activities under structure-function paradigm. Mostly IDPs are associated with malignancies, neurodegenerative diseases and heart diseases. DNA methylation is one Post Transcriptional Modification (PTM) techniques where methyl groups are added to nucleotide bases. It is responsible to control the functionality of Transcription Factors (TFs). Along with that, the structural orchestration is also affected due to PTM. Very few diseases related studies are focused on structural disordered along with methylation. OBJECTIVE: In this article, our motivation is to establish a relation between uterine leiomyoma at differential methylation rate and tissue specific disordered proteins. METHOD: In this article, we propose a framework for achieving our aforementioned object. We start with two set of data i.e., set of gene specifically related with uterine leiomyoma (GUL) and set of tissue specific proteins from uniprot (Puterine). Subsequently, 'two sample T-Test' is applied on GUL to find differentially methylated sample for uterine leiomyoma (DGUL). Comparing the gene transcripts of DGUL with the Puterine , the common biomarkers are selected (DPuterine). Thereafter the selected list of proteins is analyzed under D2P2 to find percentage disorder rate, number SCOP, number protein families and rate PTM. Proteins, with more than 10% of structural disorder rate, consider as structurally disordered (PUL disordered). Finally, to validate the listed up proteins we perform KEGG pathway and Gene Ontology analysis. RESULTS: Following the proposed framework, we start with 2246 proteins from uniprot which are kept in Puterine. Under DGUL there are 6555 genes which are differentially methylated (p-value <0.05). Only 434 proteins selected from the intersection of DGUL and Puterine. Among them only 210 proteins are fallen PUL disordered with more than 10% structural disorder. Top ten proteins under the range of 100% to 74.2% are selected shown in the article. After performing KEGG pathway analysis and Gene Ontology analysis, it is found that Q969W3 has no connection with KEGG or GO terms. CONCLUSION: After the applying the framework, we get some verified group of proteins at different stages of the proposed method. The group of 210 disordered proteins is verified from the KEGG and GO analysis. As the result is verified at satisfactory level then it can be said that the framework is successfully analyzed intrinsically disordered proteins, having a connection with differential methylation levels for a specific disease. PMID- 29577851 TI - Structural and Aggregation Properties of Alpha-Synuclein Linked to Phospholipase A2 Action. AB - BACKGROUND: Alpha-synuclein is a protein involved in the pathogenesis of Parkinson's disease. In vitro observations have shown that specific brain enriched polyunsaturated fatty acids, such as arachidonic acid, can give rise to a conformational change in alpha-synuclein and ultimately induce its fibrillation. Arachidonic acid is released by phospholipase A2 activity and clinical observations have shown a link between mutations in PLA2G6, the gene responsible for the production of phospholipase A2, and early-onset types of parkinsonism. It is unknown how phospholipase A2-driven release of arachidonic acid can affect the conformation of alphasynuclein. OBJECTIVE: The main objective of this study was to investigate if phospholipase A2-induced release of arachidonic acid can induce changes in conformation and aggregation state of alpha-synuclein. METHODS: Recombinant human alpha-synuclein was expressed and isolated and incubated in the presence of phosphatidylcholine and phosphatidylserine (PC/PS) containing liposomes. The release of free fatty acids from PC/PS liposomes by bee venom phospholipase A2 was measured with the fluorescent probe acrylodated intestinal fatty acid-binding protein (ADIFAB) and radioactive labelling by preparing liposomes in the presence of L- 3 phosphatidylcholine, 1-stearyl-2[1-14C] arachidonoyl. The effect of free fatty acid release on the conformation of alpha-synuclein was assayed by far-UV circular dichroism and resistance against V8 protease-induced limited proteolysis. Aggregation of alpha-synuclein upon exposure to phospholipase A2 induced action on PC/PS liposomes was measured using thioflavin T fluorescence, SDS-PAGE, gel filtration chromatography, and transmission electron microscopy. RAW264.7 cells were transiently transfected with human alpha-synuclein and release of arachidonic acid was quantified using radiolabeling and liquid scintillation counting. RESULTS: Phospholipase A2 is capable of releasing arachidonic acid from biomimetic phospholipid membranes. Exposure of alpha synuclein to phospholipase A2-induced release of arachidonic acid from PC/PS liposomes induces a conformational transition of the protein and leads to partial resistance against proteolytic cleavage by V8 protease. Prolonged incubation of alpha-synuclein with arachidonic acid, derived from PC/PS liposomes by phospholipase A2 leads to aggregate formation. In line with this, transiently transfected RAW264.7 cells with alpha-synuclein showed arachidonic acid release and punctate alpha-synuclein staining upon phospholipase A2 activation. The ability of arachidonic acid to drive alpha-synuclein to aggregate was independent of its oxidation state. CONCLUSION: We present data that suggest a biological context for the previously reported clinical observation that linked mutations in PLA2G6, the gene responsible for the production of phospholipase A2, and early onset types of parkinsonism. Release of arachidonic acid, independent of its oxidation state, through activation of phospholipase A2-driven hydrolysis of phospholipid membranes, leads to the structural transition and aggregation of alpha-synuclein. PMID- 29577852 TI - In-Vitro Drug Dissolution Studies in Medicinal Compounds. AB - After oral administration, drug absorption from solid dosage forms depends on the release of the drug active compounds from the dosage form, the dissolution or solubilization of the drug under physiological conditions, and the permeability across the gastrointestinal tract. Dissolution testing is an essential part of designing more effective solid dosage forms in pharmaceutical industry. Moreover, dissolution testing contributes to the selection of appropriate formulation excipients for improving the dosage form efficiency. This study aims to analyze in-vitro drug dissolution testing in solid dosage forms since 2010 in order to present a comprehensive outlook of recent trends. In doing that the previous studies in the literature are summarized in the form of a table to demonstrate the apparatuses used for dissolution testing, the media in which the solid dosage form is dissolved, the method preferred for analysis from dissolution media, the conditions of analyses and the results obtained. PMID- 29577853 TI - New Sides of Aldosterone Action in Cardiovascular System as Potential Targets for Therapeutic Intervention. AB - Aldosterone, the main mineralocorticoid hormone, plays a crucial role in the regulation of electrolyte homeostasis and blood pressure. Although this role is undoubtedly important, it is not a hormonal action that attracts the most attention. Aldosterone seems to be very important as a local messenger in the pathology of cardiovascular diseases (CVD). In the last few years, the attention was focused on the correlation between raised aldosterone level and increased risk of cardiovascular events. It has been demonstrated that aldosterone contributes to fibrosis, inflammation, endothelial dysfunction, fibrinolytic disorders, and oxidative stress leading to CVD development and progression. It used to be thought that the effects of aldosterone are mediated via classic nuclear receptors - mineralocorticoid receptors (MRs). Now we know that the mechanism of aldosterone action in the cardiovascular system (CVS) is much more complex since experimental and clinical studies indicate that MR blockade may be not sufficient to abolish aldosterone-induced harmful effects in CVS. Thus, the involvement of some other than MR, receptors, and factors is suggested. Moreover, in addition to the generally known genomic action of aldosterone, which involves MR activation, the nongenomic pathways are postulated in the mode of hormone action. More and more attention is focused on the membrane-coupled receptors, which mediate the rapid effects of aldosterone and have been already confirmed in different cells and tissues of CVS. Therefore, this brief review summarizes recent findings about new sides of aldosterone action in CVS that could be potential targets for therapeutic intervention. PMID- 29577854 TI - Flavonoids and its Neuroprotective Effects on Brain Ischemia and Neurodegenerative Diseases. AB - Brain ischemia is among the leading cause of death with majority of the cases are associated with ischemic strokes. It can occur in two forms of either focal or global ischemia. Neurodegenerative disorder such as Alzheimer and Parkinson diseases is also on the rise worldwide. These disorders have common similarities; i.e. they all affecting the central nervous system with debilitating effect to the patient. In this review, we look into the promising role of flavonoids, a natural bioactive compound found abundant in vegetables, fruits and traditional herbs. Treatment with flavonoids such as curcumin, lycopene, ginsenoside, vitexin and baicalin have shown promising neuroprotective effects against ischemic induced injury. Besides anticancer, antioxidant and immunomodulation properties, flavonoid also exerts neuroprotective effects by increases neuronal viability, increases tissue perfusion and cerebral blood flow and reduce ischemic-related apoptosis. In addition, flavonoid also exerts anti-amyloidogenic effect and reduces loss of dopaminergic neurons in the brain. These results suggesting flavonoids might be able to serve as a potential therapeutic agent in brain disorders. PMID- 29577855 TI - Nanoparticles in Cancer Treatment: Opportunities and Obstacles. AB - In the United States, the estimated number of new cancer cases in 2018 will be approx. 1.7 million. Historically, combination chemotherapy has been the primary choice of treatment. However, chemotherapeutics have pharmaceutical limitations, among which include problems with stability and aqueous solubility. Likewise, dose limiting toxicity is significant with nonspecific toxicity to healthy cells, hair loss, loss of appetite, peripheral neuropathy and diarrhea being typical side effects. The emergence of Multidrug resistance (MDR) also presents s a significant challenge for the successful treatment of cancer whereby cancer cells become cross resistant to many of the chemotherapeutic agents used. Nanotechnology presents a new frontier for cancer treatment. It holds potential in minimizing systemic toxicity through the development of functionalized particles for targeted treatment. They also provide an alternative strategy to circumvent multidrug resistance as they have a capacity to by-pass the drug efflux mechanism associated with this phenotype. Aside from the advantages they offer in treatment, nanoparticles are also emerging to be valuable diagnostic entities. This article highlights the various ways nanotechnology is being used to improve the treatment and management of cancer. We also discuss the opportunities and obstacles in this area and provide an up to date review of progress in the treatment of cancer. PMID- 29577856 TI - Blood Flow Regulates Zebrafish Caudal Vein Plexus Angiogenesis by ERK5-klf2a nos2b Signaling. AB - BACKGROUND: Vascular network formation induced by angiogenesis plays an important role in many physiological and pathological processes. However, the role of blood flow and underlying mechanisms in vascular network formation, for example for the development of the caudal vein plexus (CVP), is poorly understood. OBJECTIVE: The aim of this study was to explore the role of ERK5-klf2a-nos2b signaling in the CVP angiogenesis. METHOD AND RESULTS: In this study on tnnt2a-MO injection and chemical blood flow modulator treatment in zebrafish embryos, we demonstrated that decreased blood flow disrupted CVP formation. The hemodynamic force was quantitatively analyzed. Furthermore, CVP angiogenesis in zebrafish embryos was inhibited by disruption of the blood flow downstream effectors ERK5, klf2a, and nos2b in response to treatment with the ERK5 specific inhibitor and to injection of klf2a-MO, nos2b-MO. Overexpression of klf2a mRNA or nos2b mRNA restored vascular defects in tnnt2a or klf2a morphants. The data suggest that flow-induced ERK5-klf2a-nos2b signaling is involved in CVP angiogenesis in zebrafish embryos. CONCLUSION: We have demonstrated that blood flow is essential for vascular network formation, specifically for CVP angiogenesis in zebrafish. A novel genetic and mechanical mechanism was discovered in which ERK5 facilitates the integration of blood flow with the downstream klf2a-nos2b signaling for CVP angiogenesis. PMID- 29577857 TI - Erythropoietin Protects Retina Against Ceramide 2-Induced Damage in Rat. AB - BACKGROUND: Ceramide plays critical roles in cell proliferation, senescence and apoptosis, and is implicated in neurodegenerative diseases, etc. To clarify if ceramide plays some roles in retinal diseases, we established in vivo and in vitro retinal injury models with ceramide 2 (C2) treatment. In addition, Erythropoietin (EPO), which showed protective effects on retinal cells and blood retinal barrier (BRB), was also tested for its protection and possible mechanism(s) in these models. METHODS: Male Sprague-Dawley rats were divided into four groups, i.e., normal control, vehicle control, C2 treatment, and C2+EPO treatment. After intravitreal injection, the rats were examined for eye fundus, electroretinogram, histological study, and immunostaining, etc. In vitro, retinal neuronal cell line (R28) and the primary human retinal microvascular endothelial cells (HRMECs) were treated with C2, cell viability assay, transendothelial electrical resistance (TEER) and BRB-related molecules were studied to test the protective effect of EPO. RESULTS: Intravitreal C2-treatment caused significant vision loss in rats, as reflected by reduced b-wave amplitude, increased TUNEL positive cells and GFAP immunostaining in retina. Another major retinal injury observed was BRB breakdown following C2- treatment. Such C2-induced injuries were further confirmed by in vitro study. When HRMECs were treated with C2, the TEER was significantly reduced. The mechanisms for C2 to induce such injuries might be through evidently increased expressions of the related molecules like plasmalemma vesicle-associated protein (PLVAP or PV-1), ecto- 5'-nucleotidase (CD73) and intercellular adhesion molecule-1 (ICAM-1), as observed in C2-treated R28 cells. All these injuries induced by C2 were significantly prevented by EPO both in vivo and in vitro, and its protective mechanisms here might be, in addition to neuroprotective, closely related to its maintenance of BRB integrity, through reducing the expressions of PV-1, CD73 and ICAM-1. CONCLUSION: C2 could induce severe retinal injury, and such injuries could be effectively prevented by EPO treatment. PMID- 29577858 TI - Expression and Prognostic Relevance of GAGE1 and XAGE1 Cancer/Testis Antigens in Head and Neck Squamous Cell Carcinoma. AB - BACKGROUND: In the last decades, survival rates in head and neck squamous cell carcinoma (HNSCC) have not changed, with a five-year survival of only 50%. Thus, there is a great need for the identification of new molecular targets and development of novel therapeutic strategies. Cancer-testis antigens (CTAs) are expressed in various types of tumor but rarely in healthy normal tissues. Therefore, they appear as ideal targets for immunotherapy approaches, as well as, unique markers for cancer diagnosis/prognosis. OBJECTIVE: This study evaluated the expression pattern of cancer/testis antigens (CTA) in HNSCC samples and correlated the expression data with the clinicopathological prognostic variables. METHODS: An in silico screening was performed using all CTA genes cataloged on the CTDatabase and the expression of the eight CTA genes (ARMC3, DDX53, FTHL17, GAGE1, MAGEA11, SYCE1, TCP11, and XAGE1) was examined in 89 HNSCC and 20 normal mucosa samples using RT-PCR analysis. RESULTS: GAGE1 (48.3%), XAGE1 (40.4%) and MAGEA11 (19.1%) were frequently and specifically expressed in HNSCC samples and 68.5% of the cases expressed at least one of these antigens. Moreover, GAGE1 and XAGE1 mRNA positivity was significantly associated with the presence of metastasis in the lymph nodes (p=0.038 and p=0.023, respectively) and, by multivariate analysis, male gender (p=0.032), advanced clinical stage (p=0.018) and mRNA positivity for GAGE1 (p=0.010) were independent prognostic factors for overall survival. CONCLUSION: These findings suggest GAGE1 and XAGE1 expressions to be useful as prognostic markers for HNSCC. PMID- 29577859 TI - Update on Asthma Genetics: Results From Meta-Analyses of Candidate Gene Association Studies. AB - Several studies have investigated the risk factors associated with asthma. Both genetic and environmental factors are considered to contribute to asthma susceptibility. Individual genetic association studies usually suffer from small sample size leading to biased results. Meta-analysis is a powerful tool that has the potential to resolve this limitation by increasing the statistical power of analyses. The current review summarizes the recent knowledge concerning genetic factors involved in asthma predisposition based on meta-analyses. Using the keywords: asthma, meta-analysis, polymorphism, we searched Pubmed, Medline, Embase and Google Scholar databases for the associated articles. Genetic polymorphisms in twenty-three genes are associated with asthma risk in meta analyses. However, polymorphisms in nine genes showed none significant association. These findings are used to assess the genetic risk factors and to understand the molecular pathways related to asthma. PMID- 29577860 TI - Prognostic Value of White Blood Cell Counts and C-reactive Protein in Acute Ischemic Stroke Patients After Intravenous Thrombolysis. AB - BACKGROUND: The prognostic value of White Blood Cell (WBC) counts and C-reactive Protein (CRP) in clinical outcomes of Acute Ischemic Stroke (AIS) patients after Intravenous Thrombolysis (IVT) remains unknown. We investigated the association of WBC counts and CRP with 3-month functional outcomes and all-cause mortality in AIS patients. METHODS: 447 AIS patients treated with IVT between May 2010 and May 2017 were enrolled. WBC counts and CRP were measured within 24 hours after IVT. The main outcomes included poor functional outcomes (modified Rankin score >=3) at 3 months and 3-month all-cause mortality. RESULTS: High WBC counts were associated with poor functional outcomes (adjusted OR (odds ratio) 4.48; 95% CI (confidence interval) 2.00-10.03; P-trend<0.001) and with all-cause mortality (adjusted HR (hazard ratio) 2.19; 95% CI 1.07-4.49; P-trend=0.018). In addition, high CRP levels were associated with poor functional outcomes (adjusted OR 4.95; 95% CI 1.39-17.65; Ptrend= 0.002). However, no significant association between high CRP levels and all-cause mortality was observed (adjusted HR 2.61; 95% CI 0.80-8.47; P-trend=0.138). CONCLUSION: Our analysis indicated that elevated WBC counts and CRP levels after IVT can independently predict poor outcome among AIS patients. PMID- 29577861 TI - Kidney Dysfunction is Associated with a High Burden of Cerebral Small Vessel Disease in Primary Intracerebral Hemorrhage. AB - OBJECTIVES: To investigate the association of kidney function with the total burden of Cerebral Small Vessel Disease (CSVD) in primary Intracerebral Hemorrhage (pICH). METHODS: Cerebral magnetic resonance imagings of consecutively enrolled pICH patients were reviewed to assess for lacunes, White Matter Hyperintensity (WMH), Cerebral Microbleeds (CMBs) and Enlarged Perivascular Spaces (EPVS). Minor refinements to the CSVD score, namely modified CSVD score 1 and 2, were made by incorporating different weightings of CSVD markers. Kidney function was assessed using the estimated Glomerular Filtration Rate (eGFR). We used ordinal regression analysis to assess the association of kidney function with the CSVD score and modified scores. RESULTS: In the 108 patients included, the presence of lacunes, CMBs, MWH and basal ganglia EPVS>10 was 27.8%, 67.6%, 47.2% and 35.2%, respectively. In multivariable ordinal regression, a decreasing eGFR value was associated with an increased CSVD score [Odds Ratio (OR) 0.978, 95% Confidence Interval (CI) 0.962 to 0.995, P=0.013], modified CSVD score 1 (OR 0.973, 95% CI 0.957 to 0.990, P=0.002) and 2 (OR 0.969, 95% CI 0.953 to 0.986, P<0.001). The link between eGFR and the total burden of CSVD was significant in strictly deep pICH (P=0.011 for CSVD score; P=0.001 for modified score 1 and 2), but not strictly lobar pICH in subgroup analysis. CONCLUSIONS: Low eGFR is associated with a high burden of CSVD in patients with deep pICH, but not lobar pICH. Future studies are warranted to assess whether low eGFR is a potential therapeutic target for preventing the progress of CSVD burden for deep pICH. PMID- 29577862 TI - Increased Arterial Stiffness is Associated with Poor Collaterals in Acute Ischemic Stroke from Large Vessel Occlusion. AB - BACKGROUND: Cerebral collateral circulation is a network of arterial anastomotic channels capable of providing supplementary perfusion to brain regions in response to ischemic insults. Arterial stiffness could negatively affect collateral circulation development, by means of its effects on the structural intracerebral vasculature. OBJECTIVE: The aim of our study is to investigate a possible link between arterial stiffness and presence of collateral circulation in patients with acute ischemic stroke. METHODS: 113 patients (age: 74+/-12 years) with acute anterior ischemic stroke underwent neuroimaging examination and 24-hour blood pressure monitoring. Arterial Stiffness Index (ASI) and Pulse Pressure (PP) were assumed as surrogate measures of arterial stiffness. Collateral circulation was evaluated by means of the collateral grading system that was scored on a scale of 0-3. RESULTS: According to TOAST classification, etiology of ischemic stroke was the following: Large-Artery Atherosclerosis (LAA)(n:41), Cardioembolism (CE)(n:60), Undetermined Etiology (UE)(n:12). Logistic regression analysis showed that good predictors of poor collaterals were ASI (OR 2.78 for 0.1, 95% CI:1.19-6.50, p=0.01) and PP (OR 1.81 for 10 mmHg, 95% CI:1.01-3.22, p=0.04) in stroke from LAA. CONCLUSION: Our results suggest that, in patients with ischemic stroke from LAA, arterial stiffness may contribute to the impairment of collateral circulation and, therefore, it could reduce the beneficial effects of acute treatments. PMID- 29577863 TI - Hepatic Elimination of Drugs in Gestational Diabetes. AB - BACKGROUND: The liver is the major metabolic clearance organ for chemical agents from the human body. Pregnancy is associated with several physiological changes that may affect one or more of these factors, and also induces changes in the hepatic clearance of certain drugs. The aim of this paper was to review some of the currently available information in the field to provide some insights about the relevance of these changes on the clearance of some drugs. METHODS: A comprehensive literature search was carried out to identify eligible studies from MEDLINE/PubMed, EMBASE and SCIELO databases through 1970 first semester. RESULTS: Gestational Diabetes Mellitus (GDM) is a frequent disease commonly associated with other entities as obesity, hypertension, dyslipidemia, non-alcoholic fatty liver disease, prothrombotic conditions, changes in intestinal microbiome. These entities, together with the glycemic fluctuations associated with GDM might affect the determinants of the hepatic clearance (hepatic blood flow, the unbound fraction of drugs, and the hepatic intrinsic clearance). GDM is frequently associated with multi-drug treatments. While many of these drugs are cleared by the liver, little is known about the clinical relevance of these GDM associated pharmacokinetic changes. CONCLUSION: Considering the frequency of the disease and the effects that these pharmacokinetic changes might have on the mother and child, the need for further research seems advisable. In the meantime, cautious clinical judgment in the management of drug administration in women affected by this disease is recommended. PMID- 29577864 TI - Dyspnea in Cancer Patients: A Well-Known and Neglected Symptom. AB - BACKGROUND: Dyspnea is a very common and well-known symptom in patients with advanced cancer, but it is often neglected by physicians. Moreover, despite the high frequency of dyspnea, few controlled studies have been conducted on cancer patients. In most cases, this 'awareness of breathing with difficulty' and its severity can only be judged by the patient. Moderate or severe dyspnea is described in 20-80% of patients with advanced cancer and breathlessness is considered a prognostic factor for shorter survival, either alone or associated with other parameters. METHODS: I reviewed the literature and guidelines on the topic with the aims to focus on what is known and on future pathways to follow for the diagnosis and treatment of dyspnea. RESULTS: There is no uniformity regarding the definition of dyspnea; consequently, there is still no general agreement about which tools are the best to use in clinical practice to detect the presence and severity of this symptom. In addition to the difficulty of assessing the symptom, a further limit concerns the management of dyspnea: a very limited number of therapies, both pharmacological and otherwise, are currently available that lead to satisfactory outcomes. Opioids such as morphine remain the cornerstone of treating dyspnea. CONCLUSION: Dyspnea is a complex, multidimensional symptom that results from an interaction between factors and their causes, perception and expression. The main target of assessment and management is the intensity of dyspnea, as expressed by the patient, rather than the objective parameters of the disease. Although dyspnea is a very common symptom, debilitating and often difficult to control, especially in the terminal phase of the disease, few controlled studies have been conducted on cancer patients. Dyspnea remains a well-known but neglected symptom in advanced and terminal cancer patients. Future studies should be conducted regarding the careful assessment and management of this symptom. PMID- 29577865 TI - Synthesis and Biological Evaluation of New 1,3,4-Oxadiazoles as Potential Anticancer Agents and Enzyme Inhibitors. AB - BACKGROUND: 1,3,4-Oxadiazoles have been known with a wide variety of pharmacological activities including anticancer activity. OBJECTIVE: In this study, novel 2,5-disubstituted 1,3,4-oxadiazole derivatives were synthesized and evaluated for determining their anticancer, anticholinesterase and lipoxygenase (LOX) inhibitory activity. METHODS: All compounds were tested against C6 rat glioma, A549 human lung carcinoma and NIH/3T3 mouse embryo fibroblast cell lines to define cytotoxic concentrations and apoptosis induction levels which they cause. RESULTS: Many of the compounds exhibited remarkable potency that compounds 2a, 2b, 2e, 2h and 2j against C6 cells and compounds 2a, 2b, 2d, 2g, 2i, 2j against A549 cells were found more active than cisplatin. Compound 2d namely, 2 [(5-(4-aminophenyl)-1,3,4-oxadiazol-2-yl)thio]-1-(4-chlorophenyl)ethan-1-one induced apoptosis of A549 cells with 74.9% whereas cisplatin caused 70.9% percentage. CONCLUSION: Among them, compounds 2d and 2j against A549 cell line, compounds 2b and 2e against both tumor cell lines showed selective cytotoxicity evaluating the inhibition concentration against NIH/3T3 cell line. None of the compounds showed significant acetylcholinesterase (AChE) and lipoxygenase inhibitory activities. PMID- 29577867 TI - Platelet Activation Polymorphisms in Ischemia. AB - BACKGROUND: Ischemia is a multifactorial disorder in which several genetic and environmental factors are involved. Platelets are the major causative agents of this disease because their elevated activity and aggregation would increase the risk of atherosclerosis and thrombosis, as well as ischemia. A number of polymorphisms in platelet receptors can increase the risk of ischemia and single nucleotide polymorphisms (SNPs) have been detected in platelets. In addition, polymorphisms in other genes have been shown to cause platelet adhesion and aggregation that plays a role in ischemia. Patients respond differently to anti platelet drugs which are used to treat patients with ischemia. Polymorphisms affect patients' responses to anti-platelet drugs, for instance, by increasing platelet activity and causing resistance of platelets to these drugs. Diagnosis of these polymorphisms can greatly contribute to better prediction of prognosis and response to treatment of patients, leading to more effective therapeutic strategies and a proper approach to ischemia. CONCLUSION: In this review, we have evaluated the role of polymorphisms involved in platelet activation and development of ischemia. PMID- 29577866 TI - Synthesis and Anticancer Properties of Novel Truncated Carbocyclic Nucleoside Analogues. AB - Series of novel truncated carbocyclic nucleoside analogues have been synthesized from the versatile starting material D-ribose and their anticancer activities have been evaluated. The nucleoside analogues induced cytotoxicity in breast and ovarian cancer cell lines. These compounds are less cytotoxic to normal kidney cell line (HEK 293) as compared to the cancer cells. Among the synthesized compounds, 1b and 1d showed the better cytotoxic effect with IC50 44 and 54 MUM, in MCF7 cells, respectively. These compounds inactivate the important signaling kinases AKT and mTOR and thereby induce autophagy. Collectively our observation suggests that compound 1b and 1d inhibit the cancer cell proliferation through induction of autophagy mode of cell death. PMID- 29577868 TI - Regulation of Smooth Muscle Myosin Light Chain Phosphatase by Multisite Phosphorylation of the Myosin Targeting Subunit, MYPT1. AB - BACKGROUND: Smooth muscle contraction is triggered primarily by activation of Ca2+/calmodulin-dependent myosin light chain kinase leading to phosphorylation of the regulatory light chains of myosin II. Numerous contractile stimuli also induce inhibition of myosin light chain phosphatase thereby prolonging the contractile response. The phosphatase is a trimeric enzyme containing a catalytic subunit, a regulatory, myosin-binding subunit (MYPT1) and a third subunit of uncertain function. MYPT1 is phosphorylated at multiple sites by several kinases, which regulate phosphatase activity, protein-protein interactions and subcellular localization. The best-characterized phosphorylation events involve phosphorylation by Rho-associated coiled-coil kinase (ROCK) at T697 and T855, which inhibits phosphatase activity, and phosphorylation by cAMP- or cGMPdependent protein kinases (PKA and PKG, respectively) at S696, T697, S854 and T855, which has no effect on phosphatase activity. Furthermore, phosphorylation by ROCK at T697 and T855 prevents phosphorylation by PKA or PKG at the neighboring serine residues. Some 30 phosphorylation sites have been identified in MYPT1 with many more suggested by large-scale phosphoproteomic studies. It is important to gain as complete understanding as possible of the complex phosphorylation-mediated mechanisms of regulation of MYPT1 functions in part because of their involvement in pathological processes. For example, dysfunctional MYPT1 phosphorylation has been implicated in the pathogenesis of several vascular disorders, including type 2 diabetes. CONCLUSION: Much effort is now being devoted to the development of novel therapeutics targeting MYPT1 and specific kinases involved in the phosphorylation of MYPT1. PMID- 29577869 TI - Characterization of Liver- and Cancer-type-Organic Anion Transporting Polypeptide (OATP) 1B3 Messenger RNA Expression in Normal and Cancerous Human Tissues. AB - BACKGROUND: Membrane transport protein organic anion transporting polypeptide (OATP) 1B3 mediates the cellular uptake of many clinically important drugs including anti-cancer drugs (e.g., paclitaxel). In addition to the well recognized hepatic expression and function of OATP1B3 [herein named liver-type (Lt) OATP1B3], OATP1B3 also expresses in cancers and has been postulated to play a role in cancer therapy, presumably by facilitating the influx of anti-cancer drugs. Recently, a cancer type (Ct)-OATP1B3 mRNA variant was identified in colon and lung cancer tissues, which encodes truncated Ct-OATP1B3 with negligible transport activity. Other than in colon and lung cancers, reports on mRNA expression of OATP1B3 in other cancers cannot distinguish between the Ltand Ct OATP1B3. OBJECTIVE: The current studies were designed to characterize the expression of Lt- and Ct-OATP1B3 mRNA in ovarian, prostate, bladder, breast, and lung tissues. METHODS: Lt- and Ct-OATP1B3 isoform-specific PCR primers were utilized to determine the mRNA levels of Lt- and Ct-OATP1B3, respectively. An expression vector expressing green fluorescent protein (GFP)-tagged Lt-OATP1B3 was transiently transfected into the ovarian cancer cell line SKOV3. Confocal live-cell microscopy was utilized to determine the localization of GFP-Lt-OATP1B3 in SKOV3 cells. RESULTS: For the first time, Lt-OATP1B3 mRNA was detected in ovarian, prostate, bladder and breast cancers. The localization of GFP-Lt-OATP1B3 on the plasma membrane of SKOV3 cells after transient transfection was readily detected by confocal microscopy. CONCLUSION: Our findings are supportive of the potential role of Lt-OATP1B3 in cancer cells. PMID- 29577870 TI - Conflicts of Interest in Clinical Guidelines: Lack of Authors and Disclosures in the AAOMS White Papers. AB - PURPOSE: The purpose of this study was to evaluate current state of authorship, financial disclosures, and conflicts of interest in position papers published by the American Association of Oral and Maxillofacial Surgeons (AAOMS). MATERIALS AND METHODS: This is a cross-sectional review of the position papers published by the AAOMS from 2013 to 2017. Primary outcome variables include position papers published by the AAOMS. Secondary outcome variables include declaration of authorship, financial disclosures, and financial payments. The Open Payments Database for financial disclosures was reviewed for the year the position paper was published and the immediate preceding year. RESULTS: Ten position papers were published by the AAOMS from 2013 to 2017. Of the 10 papers, authorship was listed in 3, and none explicitly addressed the presence or absence of financial disclosures or conflicts of interest. Contributors to 3 of the 3 authored papers were found at review of the Open Payments Database to have received industry funding in the year the position paper was published and the immediate preceding year. The remuneration ranged from less than $1,000 to $554,006.02. CONCLUSION: Position papers published by the AAOMS lack standardization for authorship and statements on potential financial disclosure. The authors suggest full disclosures of authorship and authors' conflicts of interest should be stated on all position papers to provide transparency to the process. PMID- 29577871 TI - Long noncoding RNA MALAT1 regulates generation of reactive oxygen species and the insulin responses in male mice. AB - The metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long noncoding RNA and its overexpression is associated with the development of many types of malignancy. MALAT1 null mice show no overt phenotype. However, in transcriptome analysis of MALAT1 null mice we found significant upregulation of nuclear factor-erythroid 2 p45-related factor 2 (Nrf2) regulated antioxidant genes including Nqo1 and Cat with significant reduction in reactive oxygen species (ROS) and greatly reduced ROS-generated protein carbonylation in hepatocyte and islets. We performed lncRNA pulldown assay using biotinylated antisense oligonucleotides against MALAT1 and found MALAT1 interacted with Nrf2, suggesting Nrf2 is transcriptionally regulated by MALAT1. Exposure to excessive ROS has been shown to cause insulin resistance through activation of c-Jun N terminal kinase (JNK) which leads to inhibition of insulin receptor substrate 1 (IRS-1) and insulin-induced phosphorylation of serine/threonine kinase Akt. We found MALAT1 ablation suppressed JNK activity with concomitant insulin-induced activation of IRS-1 and phosphorylation of Akt suggesting MALAT1 regulated insulin responses. MALAT1 null mice exhibited sensitized insulin-signaling response to fast-refeeding and glucose/insulin challenges and significantly increased insulin secretion in response to glucose challenge in isolated MALAT1 null islets, suggesting an increased insulin sensitivity. In summary, we demonstrate that MALAT1 plays an important role in regulating insulin sensitivity and has the potential as a therapeutic target for the treatment of diabetes as well as other diseases caused by excessive exposure to ROS. PMID- 29577873 TI - Intermittent hypoxia-generated ROS contributes to intracellular zinc regulation that limits ischemia/reperfusion injury in adult rat cardiomyocyte. AB - Intermittent hypoxia (IH) has been shown to exert cardioprotective effects against ischemia/reperfusion (I/R) injury through the preservation of ion homeostasis. I/R dramatically elevated cytosolic Zn2+ and caused cardiomyocyte death. However, the role of IH exposure in the relationship between Zn2+ regulation and cardioprotection is still unclear. The aim of the present study was to study whether IH exposure could help in intracellular Zn2+ regulation, hence contributing to cardioprotection against I/R injury. Adult rat cardiomyocytes were exposed to IH (5% O2, 5% CO2 and balanced N2) for 30 min followed by 30 min of normoxia (21% O2, 5% CO2 and balanced N2). Changes in intracellular Zn2+ concentration were determined using a Zn2+-specific fluorescent dye, FluoZin-3 or RhodZin-3. Fluorescence was monitored under an inverted fluorescent or confocal microscope. The results demonstrated that I/R or 2,2'-dithiodipyridine (DTDP), a reactive disulphide compound, induced Zn2+ release from metallothioneins (MTs), subsequently causing cytosolic Zn2+ overload, which in turn increased intracellular Zn2+ entry into the mitochondria via a Ca2+ uniporter, hence inducing mitochondrial membrane potential loss, and eventually led to cell death. However, the cytosolic Zn2+ overload and cell death caused by I/R or DTDP was significantly reduced by treatment of cardiomyocytes with IH. The findings from this study suggest that IH might exert its cardioprotective effect through reducing the I/R-induced cytosolic Zn2+ overload and cell death in cardiomyocytes. PMID- 29577872 TI - Adaptive reduction of human myometrium contractile activity in response to prolonged uterine stretch during term and twin pregnancy. Role of TREK-1 channel. AB - Quiescence of myometrium contractile activity allows uterine expansion to accommodate the growing fetus and prevents preterm labor particularly during excessive uterine stretch in multiple pregnancy. However, the mechanisms regulating uterine response to stretch are unclear. We tested the hypothesis that prolonged uterine stretch is associated with decreased myometrium contractile activity via activation of TWIK-related K+ channel (TREK-1). Pregnant women at different gestational age (preterm and term) and uterine stretch (singleton and twin pregnancy) were studied, and uterine strips were isolated for measurement of contractile activity and TREK-1 channel expression/activity. Both oxytocin- and KCl-induced contraction were reduced in term vs preterm pregnancy and in twin vs singleton pregnancy. Oxytocin contraction was reduced in uterine segments exposed to 8 g stretch compared to control tissues under 2 g basal tension. TREK-1 mRNA expression and protein levels were augmented in Singleton-Term vs Singleton Preterm, and in uterine strips exposed to 8 g stretch. The TREK-1 activator arachidonic acid reduced oxytocin contraction in preterm and term, singleton and twin pregnant uterus. The TREK-1 blocker l-methionine enhanced oxytocin contraction in Singleton-Term and twin pregnant uterus, and reversed the decreases in contraction in uterine strips exposed to prolonged stretch. Carboprost-induced uterine contraction was also reduced by arachidonic acid and enhanced by l-methionine. Thus, myometrium contraction decreases with gestational age and uterine expansion in twin pregnancy. The results suggest that prolonged stretch enhances the expression/activity of TREK-1 channel, leading to decreased myometrium contractile activity and maintained healthy term pregnancy particularly in multiple pregnancy. PMID- 29577874 TI - The subesophageal ganglion modulates locust inter-leg sensory-motor interactions via contralateral pathways. AB - The neural control of insect locomotion is distributed among various body segments. Local pattern-generating circuits at the thoracic ganglia interact with incoming sensory signals and central descending commands from the head ganglia. The evidence from different insect preparations suggests that the subesophageal ganglion (SEG) may play an important role in locomotion-related tasks. In a previous study, we demonstrated that the locust SEG modulates the coupling pattern between segmental leg CPGs in the absence of sensory feedback. Here, we investigated its role in processing and transmitting sensory information to the leg motor centers and mapped the major related neural pathways. Specifically, the intra- and inter-segmental transfer of leg-feedback were studied by simultaneously monitoring motor responses and descending signals from the SEG. Our findings reveal a crucial role of the SEG in the transfer of intersegmental, but not intrasegmental, signals. Additional lesion experiments, in which the intersegmental connectives were cut at different locations, together with double nerve staining, indicated that sensory signals are mainly transferred to the SEG via the connective contralateral to the stimulated leg. We therefore suggest that, similar to data reported for vertebrates, insect leg sensory-motor loops comprise contralateral ascending pathways to the head and ipsilateral descending ones. PMID- 29577875 TI - Characterization of antibody-C1q interactions by Biolayer Interferometry. AB - IgG molecules exert important effector functions including complement-dependent cytotoxicity (CDC). Different IgG isotypes induce CDC effect with variation, largely due to their differential binding to C1q, the initiating molecule of the classical CDC pathway. Here we report a method to characterize the binding of IgG to C1q using label-free technique. With this method, we determined the binding affinities of multiple IgG1, IgG2 and IgG4 antibodies to C1q. To explore whether antigen binding to antibodies affects C1q binding, we assessed the binding of Trastuzumab and Adalimumab with bound antigen proteins to C1q. The results showed that although the two tested IgG1 mAbs alone bind C1q similarly, their FC binding to C1q was significantly impacted by antigen binding to the Fab. The data suggested that the first step of complement pathway, whether C1q binds target cell bound antibody molecules, may significantly affect the CDC activities of antibody drugs.

AB - Withering syndrome (WS) is a chronic wasting disease affecting abalone species attributed to the pathogen Candidatus Xenohaliotis californiensis (CXc). Wild populations of blue (Haliotis fulgens) and yellow (H. corrugata) abalone have experienced unusual mortality rates since 2009 off the peninsula of Baja California and WS has been hypothesized as a possible cause. Currently, little information is available about the genetic diversity of CXc and particularly the possible existence of strains differing in pathogenicity. In a recent phylogenetic analysis, we characterized five coding genes from this rickettsial pathogen. Here, we analyze those genes and two additional intergenic non-coding regions following multi-locus sequence typing (MLST) and multi-spacer typing (MST) approaches to assess the genetic variability of CXc and its relationship with blue, yellow and red (H. rufescens) abalone. Moreover, we used 16S rRNA pyrosequencing reads from gut microbiomes of blue and yellow abalone to complete the genetic characterization of this prokaryote. The presence of CXc was investigated in more than 150 abalone of the three species; furthermore, a total of 385 DNA sequences and 7117 16S rRNA reads from Candidatus Xenohaliotis californiensis were used to evaluate its population genetic structure. Our findings suggest the absence of polymorphism in the DNA sequences of analyzed loci and the presence of a single lineage of CXc infecting abalone from California (USA) and Baja California (Mexico). We posit that the absence of genetic variably in this marine rickettsia may be the result of evolutionary and ecological processes. PMID- 29577878 TI - Establishment of a tumor neovascularization animal model with biomaterials in rabbit corneal pouch. AB - AIMS: The present animal model of tumor neovascularization most often used by researchers is zebrafish. For studies on human breast cancer cell neovascularization, a new animal model was established to enable a more convenient study of tumor neovascularization. MAIN METHODS: A sodium alginate gelatin blend gel system was used to design the new animal model. The model was established using rabbit corneal pouch implantation. Then, the animal model was validated by human breast cancer cell lines MCF-7-Kindlin-2 and MCF-7-CMV. KEY FINDINGS: The experiment intuitively observed the relationship between tumor and neovascularization, and demonstrated the advantages of this animal model in the study of tumor neovascularization. SIGNIFICANCE: The use of sodium alginate gelatin blends to establish tumor neovascularization in a rabbit corneal pouch is a novel and ideal method for the study of neovascularization. It may be a better animal model for expanding the research in this area. PMID- 29577879 TI - Overexpressed miR-145 inhibits osteoclastogenesis in RANKL-induced bone marrow derived macrophages and ovariectomized mice by regulation of Smad3. AB - BACKGROUND: MicroRNAs (miRs) play an important role in osteoclastogenesis. However, no study has investigated the underlying molecular mechanisms of miR-145 in this process. The purpose of the present study was to investigate the role of miR-145 and its post-transcriptional mechanism in the progression of osteoclast differentiation. METHODS: Macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor-kB ligand (RANKL) were used to induce osteoclastogenesis originated from bone marrow-derived macrophages (BMMs). Female C57BL/6J mice were divided into sham, OVX, OVX + NC-agomir and OVX + miR-145 agomir groups. Tartrate-resistant acid phosphatase (TRAP) staining was performed to identify osteoclasts in-vitro and in-vivo. The mRNA and protein levels in osteoclast and tibia were assayed by qRT-PCR and western blotting, respectively. RESULTS: miR-145 expression was inhibited in RANKL-induced osteoclastogenesis, whereas overexpression of miR-145 attenuated it. We further found that Smad3 is a direct target gene of miR-145 by binding with its 3'-UTR. Overexpression of miR 145 significantly suppressed Smad3 mRNA and protein expression. In-vivo, miR-145 agomir treatment inhibited osteoclast activity in OVX mice by inhibiting Smad3 expression. CONCLUSION: We provide the evidence that over-expression of miR-145 could inhibit osteoclast differentiation, at least partially, by decreasing Smad3 expression. PMID- 29577880 TI - Nanoparticles designed to regulate tumor microenvironment for cancer therapy. AB - Increasing understanding in tumor pathology reveals that tumor microenvironment (TME), which supports tumor progression and poses barriers for available therapies, takes a great responsibility in inefficient treatment and poor prognosis. In recent years, the versatile nanotechnology employed in TME regulation has made great progress. The nanoparticles (NPs) can be tailored as needed to accurately target TME components by distinguishing healthy tissues from malignancy, and to regulate TME to promote tumor regression. Meanwhile, the emerging microRNAs (miRNAs) demonstrate great potentials for TME regulation, but are regrettably restricted by quick degradation. NPs systems enable the successful delivery of miRNA to TME without the limitation, expanding the application of nucleic acid drug. In this review, we summarized recent NPs-based strategies aiming at regulating TME in different ways, including anti angiogenesis, extracellular matrix (ECM) remodeling, tumor-associated fibroblasts (TAFs) treatment and tumor-associated macrophages (TAMs) treatment, along with the miRNAs-loaded NPs for TME regulation. Catching and utilizing the features of TME for NPs design can contribute to reversing drug-resistance, optimized drug distribution, and eventually more efficient cancer therapy. PMID- 29577881 TI - On Doctors and Their Operas: A Critical (and Lyrical) Analysis of Medicine in Opera. AB - The goal of this research was to analyze the opera repertoire in terms of contents of physician roles. An additional goal was to pinpoint significant characters and passages that exemplify the changing role and perception of medicine in society over five centuries. A systematic search was performed. Musical characteristics and performing roles, and their determinants, were tabulated and formally analyzed. Of 493 operas listed, 53 (10.7%) were identified as having either a patient and/or doctor as characters. These operas span 239 years, from 1777 to 2016. Beyond unspecified Family Medicine and Generalists, some operas could be attributed to medical specialties, including 3 (5.7%) to Respiratory. Most interestingly, the 34 operas (6.9%) with physician roles are all represented by male characters, distributed by voice register mostly in the grave chords. Overall, the composer that appears with the highest interest in reporting disease is Giuseppe Verdi, with nine operas that include medical doctors. Finally, a trend can be observed regarding the evolving role of doctors, from mostly minor, buffal roles, either with magical or comical components in the 18th century, to a professional/technical physician more recently. Opera depicts a changing perception of the roles of doctors throughout history, with a blatant gender bias that still persists. PMID- 29577882 TI - TPC2-mediated Ca2+ signaling is required for the establishment of synchronized activity in developing zebrafish primary motor neurons. AB - During the development of the early spinal circuitry in zebrafish, spontaneous Ca2+ transients in the primary motor neurons (PMNs) are reported to transform from being slow and uncorrelated, to being rapid, synchronized and patterned. In this study, we demonstrated that in intact zebrafish, Ca2+ release via two-pore channel type 2 (TPC2) from acidic stores/endolysosomes is required for the establishment of synchronized activity in the PMNs. Using the SAIGFF213A;UAS:GCaMP7a double-transgenic zebrafish line, Ca2+ transients were visualized in the caudal PMNs (CaPs). TPC2 inhibition via molecular, genetic or pharmacological means attenuated the CaP Ca2+ transients, and decreased the normal ipsilateral correlation and contralateral anti-correlation, indicating a disruption in normal spinal circuitry maturation. Furthermore, treatment with MS 222 resulted in a complete (but reversible) inhibition of the CaP Ca2+ transients, as well as a significant decrease in the concentration of the Ca2+ mobilizing messenger, nicotinic acid adenine diphosphate (NAADP) in whole embryo extract. Together, our new data suggest a novel function for NAADP/TPC2-mediated Ca2+ signaling in the development, coordination, and maturation of the spinal network in zebrafish embryos. PMID- 29577883 TI - The cellular prion protein promotes olfactory sensory neuron survival and axon targeting during adult neurogenesis. AB - The cellular prion protein (PrPC) has been associated with diverse biological processes including cell signaling, neurogenesis, and neuroprotection, but its physiological function(s) remain ambiguous. Here we determine the role of PrPC in adult neurogenesis using the olfactory system model in transgenic mice. Olfactory sensory neurons (OSNs) within the olfactory sensory epithelium (OSE) undergo neurogenesis, integration, and turnover even into adulthood. The neurogenic processes of proliferation, differentiation/maturation, and axon targeting were evaluated in wild type, PrP-overexpressing, and PrP-null transgenic mice. Our results indicate that PrPC plays a role in maintaining mature OSNs within the epithelium: overexpression of PrPC resulted in greater survival of mitotically active cells within the OSE, whereas absence of prion protein resulted in fewer cells being maintained over time. These results are supported by both quantitative PCR analysis of gene expression and protein analysis characteristic of OSN differentiation. Finally, evaluation of axon migration determined that OSN axon targeting in the olfactory bulb is PrPC dose-dependent. Together, these findings provide new mechanistic insight into the neuroprotective role for PrPC in adult OSE neurogenesis, whereby more mature neurons are stably maintained in animals expressing PrPC. PMID- 29577884 TI - Regional-specific effects of cerebral ischemia/reperfusion and dehydroepiandrosterone on synaptic NMDAR/PSD-95 complex in male Wistar rats. AB - Excessive glutamate efflux and N-methyl-D-aspartate receptor (NMDAR) over activation represent well-known hallmarks of cerebral ischemia/reperfusion (I/R) injury, still, expression of proteins involved in this aspect of I/R pathophysiology show inconsistent data. Neurosteroid dehydroepiandrosterone (DHEA) has been proposed as potent NMDAR modulator, but its influence on I/R induced changes up to date remains questionable. Therefore, I/R-governed alteration of vesicular glutamate transporter 1 (vGluT1), synaptic NMDAR subunit composition, postsynaptic density protein 95 (PSD-95) and neuronal morphology alone or following DHEA treatment were examined. For that purpose, adult male Wistar rats were treated with a single dose of vehicle or DHEA (20 mg/kg i.p.) 4 h following sham operation or 15 min bilateral common carotid artery occlusion. Western blot was used for analyses of synaptic protein expressions in hippocampus and prefrontal cortex, while neuronal morphology was assessed using Nissl staining. Regional-specific postischemic changes were detected on protein level i.e. signs of neuronal damage in CA1 area was accompanied with hippocampal vGluT1, NR1, NR2B enhancement and PSD-95 decrement, while histological changes observed in layer III were associated with decreased NR1 subunit in prefrontal cortex. Under physiological conditions DHEA had no effect on protein and histological appearance, while in ischemic milieu it restored hippocampal PSD-95 and NR1 in prefrontal cortex to the control level. Along with intact neurons, ones characterized by morphology observed in I/R group were also present. Future studies involving NMDAR-related intracellular signaling and immunohistochemical analysis will reveal precise effects of I/R and DHEA treatment in selected brain regions. PMID- 29577885 TI - Primary microglia isolation from mixed cell cultures of neonatal mouse brain tissue. AB - BACKGROUND: Microglia are the main resident immunological cells of the central nervous system (CNS) that are functionally equivalent to macrophages. However, due to the cellular heterogeneity of the brain, it is technically challenging to obtain highly specific, healthy microglia with the desired phenotype in sufficient yield for in vivo experiments. NEW METHOD: This study presents a new and easy method for the isolation of microglia cells from mouse pups (P1-P3). This method consists of a 20-day protocol, divided in three sections: mixed cell culture, culture maintaining (astrocytes growing), and isolation after astrocytes confluence. RESULTS: This procedure produces microglia with no astrocyte, neuron and oligodendrocyte precursors cells contamination that are functionally active to answer inflammatory responses based on the measurement of cell and inflammatory markers. This technique requires approximately three hours for the isolation of neonatal mixed cell culture, 20 to 22 days for microglia growing and two days before starting experiments from pure and healthy microglia. COMPARISON WITH EXISTING METHODS AND CONCLUSIONS: This study presents an isolation protocol that is adapted from existing methods and is economic, rapid, not tedious, with little manipulation time and work. This method also allows to isolate large amount of high specific microglia cells with no specific phenotype and with great reproducibility and efficiently. This study provides a detailed description of the methods that is routinely used in our laboratory for the isolation and the culture of microglia, with emphasis on the steps that are deemed most critical for obtaining large amount of pure and healthy cultures. PMID- 29577886 TI - Mouse models of ALS: Past, present and future. AB - Genome sequencing of both sporadic and familial patients of Amyotrophic Lateral Sclerosis (ALS) has led to the identification of new genes that are both contributing and causative in the disease. This gene discovery has come at an unprecedented rate, and much of it in recent years. Knowledge of these genetic mutations provides us with opportunities to uncover new and related mechanisms, increasing our understanding of the disease and bringing us closer to defined therapies for patients. Mouse models have played an important role in our current understanding of the pathophysiology of ALS and have served as important preclinical models in testing new therapeutics. With these new gene discoveries, new mouse models will follow. The information derived from these new models will depend on the careful construction and importantly, an understanding of the capabilities and limitations of each of the models. The genetic discovery in ALS comes at a time when genetic engineering technologies in mice are highly efficient through CRISPR/Cas9 and can be applied to a wide array of genetic backgrounds. New mouse resources in the forms of the Collaborative Cross and Diversity Outbred panels provide us with unique opportunities to study these mutations on diverse genetic backgrounds, and importantly in the context of a population. This review focuses on the mouse models of the past and present, and discusses exciting new opportunities for mouse models of the future. PMID- 29577887 TI - Disinhibiting neurons in the dorsomedial hypothalamus delays the onset of exertional fatigue and exhaustion in rats exercising in a warm environment. AB - Stimulants cause hyperthermia, in part, by increasing heat generation through exercise. Stimulants also delay the onset of fatigue and exhaustion allowing animals to exercise longer. If used in a warm environment, this combination (increased exercise and decreased fatigue) can cause heat stroke. The dorsomedial hypothalamus (DMH) is involved in mediating locomotion from stimulants. Furthermore, inhibiting the DMH decreases locomotion and prevents hyperthermia in rats given stimulants in a warm environment. Whether the DMH is involved in mediating exercise-induced fatigue and exhaustion is not known. We hypothesized that disinhibiting neurons in the dorsomedial hypothalamus (DMH) would delay the onset of fatigue and exhaustion in animals exercising in a warm environment. To test this hypothesis, we used automated video tracking software to measure fatigue and exhaustion. In rats, using wearable mini-pumps, we demonstrated that disinhibiting the DMH, via bicuculline perfusion (5 uM), increased the duration of exercise in a warm environment as compared to control animals (25 +/- 3 min vs 15 +/- 2 min). Bicuculline-perfused animals also had higher temperatures at exhaustion (41.4 +/- 0.2 degrees C vs 40.0 +/- 0.4 degrees C). Disinhibiting neurons in the DMH also increased the time to fatigue. Our data show that the same region of the hypothalamus that is involved in mediating locomotion to stimulants, is also involved in controlling exhaustion and fatigue. These findings have implications for understanding the cause and treatment of stimulant induced-hyperthermia. PMID- 29577888 TI - Inhibition of basal and amphetamine-stimulated extracellular signal-regulated kinase (ERK) phosphorylation in the rat forebrain by muscarinic acetylcholine M4 receptors. AB - The mitogen-activated protein kinase (MAPK), especially its extracellular signal regulated kinase (ERK) subfamily, is a group of kinases enriched in the mammalian brain. While ERK is central to cell signaling and neural activities, the regulation of ERK by transmitters is poorly understood. In this study, the role of acetylcholine in the regulation of ERK was investigated in adult rat striatum in vivo. We focused on muscarinic M1 and M4 receptors, two principal muscarinic acetylcholine (mACh) receptor subtypes in the striatum. A systemic injection of the M1-preferring antagonist telenzepine did not alter ERK phosphorylation in the two subdivisions of the striatum, the caudate putamen and nucleus accumbens. Similarly, telenzepine did not affect ERK phosphorylation in the medial prefrontal cortex (mPFC), hippocampus, and cerebellum. Moreover, telenzepine had no effect on the ERK phosphorylation induced by dopamine stimulation with the psychostimulant amphetamine. In contrast to telenzepine, the M4-preferring antagonist tropicamide consistently increased ERK phosphorylation in the striatum and mPFC. This increase was rapid and transient. Tropicamide and amphetamine when coadministered at subthreshold doses induced a significant increase in ERK phosphorylation. These results demonstrate that mACh receptors exert a subtype specific modulation of ERK in striatal and mPFC neurons. While the M1 receptor antagonist has no effect on ERK phosphorylation, M4 receptors inhibit constitutive and dopamine-stimulated ERK phosphorylation in these dopamine innervated brain regions. PMID- 29577889 TI - Amyloid beta peptides, locus coeruleus-norepinephrine system and dense core vesicles. AB - The evolution of peptidergic signaling systems in the central nervous system serves a distinct and crucial role in brain processes and function. The diversity of physiological peptides and the complexity of their regulation and secretion from the dense core vesicles (DCV) throughout the brain is a topic greatly in need of investigation, though recent years have shed light on cellular and molecular mechanisms that are summarized in this review. Here, we focus on the convergence of peptidergic systems onto the Locus Coeruleus (LC), the sole provider of norepinephrine (NE) to the cortex and hippocampus, via large DCV. As the LC-NE system is one of the first regions of the brain to undergo degeneration in Alzheimer's Disease (AD), and markers of DCV have consistently been demonstrated to have biomarker potential for AD progression, here we summarize the current literature linking the LC-NE system with DCV dysregulation and Abeta peptides. We also include neuroanatomical data suggesting that the building blocks of senile plaques, Abeta monomers, may be localized to DCV of the LC and noradrenergic axon terminals of the prefrontal cortex. Finally, we explore the putative consequences of chronic stress on Abeta production and the role that DCV may play in LC degeneration. Clinical data of immunological markers of DCV in AD patients are discussed. PMID- 29577890 TI - Host and parasite morphology influence congruence between host and parasite phylogenies. AB - Comparisons of host and parasite phylogenies often show varying degrees of phylogenetic congruence. However, few studies have rigorously explored the factors driving this variation. Multiple factors such as host or parasite morphology may govern the degree of phylogenetic congruence. An ideal analysis for understanding the factors correlated with congruence would focus on a diverse host-parasite system for increased variation and statistical power. In this study, we focused on the Brueelia-complex, a diverse and widespread group of feather lice that primarily parasitise songbirds. We generated a molecular phylogeny of the lice and compared this tree with a phylogeny of their avian hosts. We also tested for the contribution of each host-parasite association to the overall congruence. The two trees overall were significantly congruent, but the contribution of individual associations to this congruence varied. To understand this variation, we developed a novel approach to test whether host, parasite or biogeographic factors were statistically associated with patterns of congruence. Both host plumage dimorphism and parasite ecomorphology were associated with patterns of congruence, whereas host body size, other plumage traits and biogeography were not. Our results lay the framework for future studies to further elucidate how these factors influence the process of host parasite coevolution. PMID- 29577891 TI - Assessment of two CRISPR-Cas9 genome editing protocols for rapid generation of Trypanosoma cruzi gene knockout mutants. AB - CRISPR/Cas9 technology has been used to edit genomes in a variety of organisms. Using the GP72 gene as a target sequence, we tested two distinct approaches to generate Trypanosoma cruzi knockout mutants using the Cas9 nuclease and in vitro transcribed single guide RNA. Highly efficient rates of disruption of GP72 were achieved either by transfecting parasites stably expressing Streptococcus pyogenes Cas9 with single guide RNA or by transfecting wild type parasites with recombinant Staphylococcus aureus Cas9 previously associated with single guide RNA. In both protocols, we used single-stranded oligonucleotides as a repair template for homologous recombination and insertion of stop codons in the target gene. PMID- 29577892 TI - A partition of Toxoplasma gondii genotypes across spatial gradients and among host species, and decreased parasite diversity towards areas of human settlement in North America. AB - Toxoplasma gondii counts among the most consequential food-borne parasites, and although the parasite occurs in a wide range of wild and domesticated animals, farms may constitute a specific and important locus of transmission. If so, parasites in animals that inhabit agricultural habitats might be suspected of harbouring genetically distinct parasite types. To better understand habitat effects pertinent to this parasite's transmission, we compiled and analysed existing genotypic data of 623 samples from animals across a proximity gradient from areas of human settlement to the wilderness in North America. To facilitate such analysis, T. gondii isolates were divided into three groups: (i) from farm bound animals (with the most limited home ranges on farms); (ii) from free roaming animals (with wider home ranges on or near farms); and (iii) from wildlife. In addition, parasite genotype distribution in different animal species was analysed. We observed no absolute limitation of any of five major genotypes to any one habitat; however, the frequency of four genotypes decreased across the gradient from the farm-bound group, to the free-roaming group, then the wildlife, whereas a fifth genotype increased along that gradient. Genetic diversity was greater in free-roaming than in farm-bound animals. The genotypic composition of parasites in wildlife differed from those in farm-bound and free-roaming animals. Furthermore, parasite genotypes differed among host species. We conclude that T. gondii genotype distributions are influenced by the spatial habitat and host species composition, and parasite diversity decreases towards areas of human settlement, elucidating facts which may influence transmission dynamics and zoonotic potential in this ubiquitous but regionally variable parasite. PMID- 29577894 TI - Bilateral quinolinic acid-induced lipid peroxidation, decreased striatal monoamine levels and neurobehavioral deficits are ameliorated by GIP receptor agonist D-Ala2GIP in rat model of Huntington's disease. AB - Huntington's disease (HD) is an inherited complex progressive neurodegenerative disorder with an established etiopathology linked to neuronal oxidative stress and corticostriatal excitotoxicity. Present study explores the effects of glucose dependent insulinotropic polypeptide (GIP) receptor agonist on the neurobehavioral sequelae of quinolinic acid-induced phenotype of Huntington's disease in rats. Bilateral administration of quinolinic acid (300 nmol/4 MUl) to the rat striatum led to characteristic deficits in, locomotor activity, motor coordination, neuromuscular coordination and short-term episodic memory. Therapeutic treatment for 14 days with a stable and brain penetrating GIP receptor agonist, D-Ala2GIP (100 nmol/kg, i.p.), attenuated the neurobehavioral deficits due to quinolinic acid (QA) administration. Protective actions of D Ala2GIP were sensitive to blockade with a GIP receptor antagonist, (Pro3)GIP (50 nmol/kg, i.p.), indicating specific involvement of GIP receptor signaling pathway. Stimulation of GIP receptor with D-Ala2GIP attenuated lipid peroxidation, evidenced by reduced levels of brain malondialdehyde (MDA), and restoration of reduced glutathione (GSH) levels in brain. Quinolinic acid administration led to significant loss of striatal monoamines, e.g., norepinephrine, epinephrine, serotonin, dopamine, and metabolites, 3,4 Dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA) and 5 Hydroxyindoleacetic acid (5-HIAA). D-Ala2GIP attenuated the QA-induced depletion of striatal monoamines, without affecting the monoamine degradation pathways. Thus, observed effects with D-Ala2GIP in the QA-induced Huntington's disease model could be attributable to reduction in lipid peroxidation, restoration of endogenous antioxidants and decreased striatal monoamine levels. These findings together suggest that stimulation of GIP receptor signaling pathway in brain could be a potential therapeutic strategy in the symptomatic management of Huntington's disease. PMID- 29577893 TI - Participation of transient receptor potential vanilloid 1 in paclitaxel-induced acute visceral and peripheral nociception in rodents. AB - The clinical use of paclitaxel as a chemotherapeutic agent is limited by the severe acute and chronic hypersensitivity caused when it is administered via intraperitoneal or intravenous routes. Thus far, evidence has suggested that transient receptor potential vanilloid-1 (TRPV1) has a key role in the chronic neuropathy induced by paclitaxel. Despite this, the role of TRPV1 in paclitaxel related acute nociception, especially the development of visceral nociception, has not been evaluated. Thus, the goal of this study was to evaluate the participation of TRPV1 in a model of acute nociception induced by paclitaxel in rats and mice. A single intraperitoneal (i.p.) paclitaxel administration (1 mg/kg, i.p.) produced an immediate visceral nociception response 1 h after administration, caused mechanical and heat hypersensitivity, and diminished burrowing behaviour 24 h after administration. These nociceptive responses were reduced by SB-366791 treatment (0.5 mg/kg, i.p., a TRPV1 antagonist). In addition, TRPV1-positive sensory fibre ablation (using resiniferatoxin, 200 ug/kg, s.c.) reduced visceral nociception and mechanical or heat hypersensitivity caused by paclitaxel injection. Similarly, TRPV1 deficient mice showed a pronounced reduction in mechanical allodynia to paclitaxel acute injection and did not develop heat hypersensitivity. Moreover, 24 h after its injection, paclitaxel induced chemical hypersensitivity to capsaicin (a TRPV1 agonist, 0.01 nmol/site) and increased TRPV1 immunoreactivity in the dorsal root ganglion and sciatic nerve. In conclusion, TRPV1 is involved in mechanical and heat hypersensitivity and spontaneous-pain behaviour induced 24 h after a single paclitaxel injection. This receptor is also involved in visceral nociception induced immediately after paclitaxel administration. PMID- 29577895 TI - Biophysical characteristics of hematopoietic cells during division. AB - Cell division is managed by a complex and coordinated sequence of cytoskeleton alterations that give rise to major morphological changes. During dividing the cleavage furrow of the cell is significantly stiffened due to the accumulation of actomyosin. However, it is unclear whether the stiffness on top of the cell is changed or not. Here, we used atomic force microscopy to measure stiffness on this location of non-adhesion Jurkat T cell and its derivative D1.1 cell from interphase to cytokinesis. The results showed that during division the cell stiffness significantly increases at anaphase and telophase. These increases in cell stiffness are most likely due to the cell surface tension created by the pulling forces of the microtubules to separate sister chromatids in the anaphase and the contraction forces of the contractile ring to separate the mother cell into daughters in the telophase. The dynamic measurement of cell elasticity during cell division may be used as a tool to gain further insight into the involved molecules and mechanisms. PMID- 29577896 TI - Platelet endothelial aggregation receptor-1 (PEAR1) is involved in C2C12 myoblast differentiation. AB - C2C12 murine myoblasts are a common model for studying muscle differentiation. Platelet endothelial aggregation receptor-1 (PEAR1), an epidermal growth factor repeat-containing transmembrane receptor, is known to participate in platelet contact-induced activation. In the present study, we demonstrated that PEAR1 is involved in the differentiation of C2C12 murine myoblasts. Western blotting and immunofluorescence staining were used to determine PEAR1 expression and localization during C2C12 cell differentiation. Subsequently, PEAR1 expression was activated and inhibited using clustered regularly interspaced short palindromic repeats-dCas9 technology to explore its effects on this process. PEAR1 expression was found to increase over the course of C2C12 cell differentiation. This protein was predominately localized on the membrane of these cells, where it clustered upon induction of differentiation. Expression of the myogenic markers Desmin, MYOG, and MYH2 revealed that PEAR1 positively regulated C2C12 cell differentiation. Moreover, induction of muscle injury by administration of bupivacaine to mice indicated that PEAR1 might play a role in muscle regeneration. In summary, our study confirmed the involvement of PEAR1 in C2C12 cell differentiation, contributing to our understanding of the molecular mechanisms underlying muscle development. PMID- 29577897 TI - The RNA binding protein tristetraprolin down-regulates autophagy in lung adenocarcinoma cells. AB - Tristetraprolin (TTP) is the most well-known member of RNA-binding zinc-finger protein that play a significant role in accelerating mRNA decay. Increasingly studies have reported that TTP was functioned as a tumor suppressor gene in several types of carcinomas, while its underlying mechanism is not clear yet. In the current study, we found that TTP overexpression decreased cell proliferation and increased cell death in lung adenocarcinoma cells, with the cell cycle arrest at the S phase. Remarkably, instead of inducing cell apoptosis directly, TTP overexpression alters cell autophagy. Our studies demonstrate that TTP overexpression has no effect on apoptosis related genes, but decreases the expression of autophagy-related genes, including Beclin 1 and LC3II. The level of autophagy flux assessed by infection with the mGFP-RFP-LC3 adenovirus construction has been blocked by TTP overexpression. Moreover, the autophagic vacuoles number detected by transmission electron microscopy decreased with TTP expression up-regulation. Our results indicate, for the first time, that TTP suppresses cell proliferation and increases cell death through cell autophagy pathway in lung cancer cells. Our study provides a new angle of view for TTP function as a tumor suppressor which could be targeted in tumor treatment. PMID- 29577898 TI - Reproductive endocrinology of environmental nitrate. AB - Nitrate is a widespread contaminant of aquatic ecosystems and drinking water. It is also broadly active in organismal physiology, and as such, has the potential to both enhance and disrupt normal physiological function. In animals, nitrate is a proposed endocrine disrupter that is converted in vivo to nitrite and nitric oxide. Nitric oxide, in particular, is a potent cell signaling molecule that participates in diverse biological pathways and events. Here, we review in vivo nitrate cycling and downstream mechanistic physiology, with an emphasis on reproductive outcomes. However, in many cases, the research produces contradictory results, in part because there is good evidence that nitrate follows a non-monotonic dose-response curve. This conundrum highlights an array of opportunities for scientists from different fields to collaborate for a full understanding of nitrate physiology. Opposing conclusions are especially likely when in vivo/in vitro, long term/short term, high dose/low dose, or hypoxia/normoxia studies are compared. We conclude that in vivo studies are most appropriate for testing an organism's integrated endocrine response to nitrate. Based on the limited available studies, there is a generalized trend that shorter term studies (less than 1 month) or studies involving low doses (<=5 mg/L NO3-N) cause steroid hormone levels to decline. Studies that last more than a month and/or involve higher, but still environmentally relevant, exposures (>50-100 mg/L NO3-N) cause steroid hormone levels to increase. Very high nitrate doses (>500 mg/L NO3-N) are cytotoxic in many species. Hypoxia and acidity are likely to intensify the effects of nitrate. For study design, degree of study animal reproductive maturity or activity is important, with immature/reproductively quiescent animals responding to nitrate differently, compared with reproductively active animals. A detailed table of studies is presented. PMID- 29577899 TI - Integrin expression and glycosylation patterns regulate cell-matrix adhesion and alter with breast cancer progression. AB - Integrins are the major cell adhesion glycoproteins involved in cell extracellular matrix (ECM) interaction and metastasis. Further, glycosylation on integrin is necessary for its proper folding and functionality. Herein, differential expression of integrins viz., alphavbeta3 and alphavbeta6 was examined in MDA-MB-231, MDA-MB-468 and MCF-10A cells, which signify three different stages of breast cancer development from highly metastatic to non tumorigenic stage. The expression of alphavbeta3 and alphavbeta6 integrins at mRNA and protein levels was observed in all three cell lines and the results displayed a distinct pattern of expression. Highly metastatic cells showed enhanced expression of alphavbeta3 than moderate metastatic and non-tumorigenic cells. The scenario was reversed in case of alphavbeta6 integrin, which was strongly expressed in moderate metastatic and non-tumorigenic cells. N glycosylation of alphavbeta3 and alphavbeta6 integrins is required for the attachment of cells to ECM proteins like fibronectin. The cell adhesion properties were found to be different in these cancer cells with respect to the type of integrins expressed. The results testify that alphavbeta3 integrin in highly metastatic cells, alphavbeta6 integrin in both moderate metastatic and non tumorigenic cells play an important role in cell adhesion. The investigation typify that N-glycosylation on integrins is also necessary for cell-ECM interaction. Further, glycosylation inhibition by Swainsonine is found to be more detrimental to invasive property of moderate metastatic cells. Conclusively, types of integrins expressed as well as their N-glycosylation pattern alter during the course of breast cancer progression. PMID- 29577900 TI - Protective effects of kenpaullone on cardiomyocytes following H2O2-induced oxidative stress are attributed to inhibition of connexin 43 degradation by SGSM3. AB - A previous study showed that small G protein signaling modulator 3 (SGSM3) was highly correlated with Cx43 in heart functions and that high levels of SGSM3 may induce Cx43 turnover through lysosomal degradation in infarcted rat hearts. Here, we investigated the protective effects of kenpaullone on cardiomyocytes following H2O2-induced oxidative stress mediated by the interaction of SGSM3 with Cx43. We found that the gap junction protein Cx43 was significantly down-regulated in an H2O2 concentration-dependent manner, whereas expression of SGSM3 was up-regulated upon H2O2 exposure in H9c2 cells. The effect of kenpaullone pretreatment on H2O2 induced cytotoxicity was evaluated in H9c2 cells. H2O2 markedly increased the release of lactate dehydrogenase (LDH), while kenpaullone pretreatment suppressed LDH release in H9c2 cells. Moreover, kenpaullone pretreatment significantly reduced ROS fluorescence intensity and significantly down-regulated the level of apoptosis-activating genes (cleaved caspase-3, cleaved caspase-9 and cytochrome C), autophagy markers (LC3A/B), and the Cx43-interacting partner SGSM3. These results suggest that kenpaullone plays a role in protecting cardiomyocytes from oxidative stress and that the turnover of Cx43 through SGSM3-induced lysosomal degradation underlies the anti-apoptotic effect of kenpaullone. PMID- 29577901 TI - O-GlcNAc site-mapping of liver X receptor-alpha and O-GlcNAc transferase. AB - The Liver X Receptor alpha (LXRalpha) belongs to the nuclear receptor superfamily and plays an essential role in regulating cholesterol, lipid and glucose metabolism and inflammatory responses. We have previously shown that LXRalpha is post-translationally modified by O-linked beta-N-acetyl-glucosamine (O-GlcNAc) with increased transcriptional activity. Moreover, we showed that LXRalpha associates with O-GlcNAc transferase (OGT) in vitro and in vivo in mouse liver. In this study, we report that human LXRalpha is O-GlcNAc modified in its N terminal domain (NTD) by identifying a specific O-GlcNAc site S49 and a novel O GlcNAc modified peptide 20LWKPGAQDASSQAQGGSSCILRE42. However, O-GlcNAc site mutations did not modulate LXRalpha transactivation of selected target gene promoters in vitro. Peptide array and co-immunoprecipitation assays demonstrate that LXRalpha interacts with OGT in its NTD and ligand-binding domain (LBD) in a ligand-independent fashion. Moreover, we map two new O-GlcNAc sites in the longest OGT isoform (ncOGT): S437 in the tetratricopeptide repeat (TPR) 13 domain and T1043 in the far C-terminus, and a new O-GlcNAc modified peptide (amino acids 826-832) in the intervening region (Int-D) within the catalytic domain. We also map four new O-GlcNAc sites in the short isoform sOGT: S391, T393, S399 and S437 in the TPRs 11-13 domain. Future studies will reveal the biological role of identified O-GlcNAc sites in LXRalpha and OGT. PMID- 29577902 TI - Identification of aberrant circular RNA expression and its potential clinical value in primary great saphenous vein varicosities. AB - This study aimed to identify aberrant circRNA expression in primary great saphenous vein varicosities (PGSVVs) and investigate its potential clinical significance. High-throughput sequencing was applied to analyze the differential expression of circRNAs in three paired vein samples of PGSVVs and a control group. Computational bioinformatics analyses, including gene ontology (GO) analysis and encyclopedia of genes and genomes (KEGG) pathway analysis, were performed to further enrich microRNA data. Real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to verify the selected aberrant circRNAs in all vein samples, and a receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic and potential clinical significance. A total of 232 circRNAs were significantly aberrantly expressed in PGSVVs, including 105 and 127 upregulated and downregulated circRNAs, respectively. The predicted top 10 downstream miRNAs of the significantly altered circRNAs are hsa-miR-103a-2-5p, hsa-miR-141-5p, hsa-miR-3692-5p, hsa-miR-4659a 3p, hsa-miR-4659b-3p, hsa-miR-4691-5p, hsa-miR-4778-3p, hsa-miR-6738-3p, hsa-miR 6792-3p and hsa-miR-6873-3p. GO analysis revealed that the most enriched and meaningful biological process, cellular component, and molecular function terms were related to the regulation of catabolic processes, the cytoplasm and ATP binding, respectively. The most enriched and meaningful pathways revealed by KEGG pathway analysis were related to "axon guidance" "vitamin digestion and absorption" and "NF-Kappa B signaling pathway". Hsa_circ_0006427 (P = 0.007), hsa_circ_0089810 (P = 0.044) and hsa_circ_0005267 (P = 0.049) were significantly downregulated in the PGSVV group relative to their expression levels in the control group, and the area under the ROC curve was 0.9091, 0.8025 and 0.8148, respectively. This study demonstrated that circRNAs were differentially expressed in PGSVVs, and highlights the crucial roles of circRNAs in the pathogenesis of PGSVVs and indicates that hsa_circ_0006427, hsa_circ_0089810 and hsa_circ_0005267 might be potential diagnostic and clinical biological markers. PMID- 29577903 TI - Hypertonic saline regulates microglial M2 polarization via miR-200b/KLF4 in cerebral edema treatment. AB - BACKGROUND: Hypertonic saline (HS) has been used clinically for treatment of cerebral edema for decades. Previously we have demonstrated that HS alleviates cerebral edema via regulating water/ion channel protein and attenuating neuroinflammation. However, whether HS treatment triggers microglia polarization and its regulatory mechanism during this process is unclear. METHODS AND RESULTS: The Sprague-Dawley (SD) rats that underwent right-sided middle cerebral artery occlusion (MCAO) were used for assessment of neuroinflammation and microglia functions. Treatment of 10% HS not only significantly reduced infarct size and ipsilateral ischemic hemispheric brain water content (BWC) via attenuating ischemia-induction of TNF-alpha, IL-1beta, microglia M1 markers (iNOS, CD86) and miR-200b, but also increased neurotrophic factors such as IL-10 and IL-4, microglia M2 markers (Arg1, CD206) and Kruppel-like factor 4 (KLF4). Similar changes were confirmed in primary microglial cells subjected to hypoxia with/without HS in vitro. Importantly, overexpression of miR-200b was able to induce microglia M1 polarization via directly targeting KLF4. Restoring KLF4 expression abolished this effect. On the contrary, miR-200b inhibitor or KLF4 overexpression led to microglia M2 polarization. Mechanistically, KLF4 directly binds to promoter region of Agr1, thus inducing its transcription. Similar to treatment of HS, experimental overexpression of KLF4 in vivo exerted significant beneficial effects on ischemia-induced cerebral edema. However, knockdown of KLF4 abrogated the benefits of HS. CONCLUSIONS: Hypertonic saline regulates microglial M2 polarization via miR-200b/KLF4 during its treatment of cerebral edema. This study may provide new insights of HS-related therapy for cerebral edema. PMID- 29577904 TI - Giantin is required for coordinated production of aggrecan, link protein and type XI collagen during chondrogenesis. AB - Extracellular matrix (ECM) constitutes a proper micro-environment for cell proliferation, migration and differentiation, as well as playing pivotal roles in developmental processes including endochondral ossification. Cartilage ECM is mainly composed of fibrous proteins, including collagen, proteoglycan, and hyaluronan. Because almost all ECM components are transported by intracellular vesicular transport systems, molecules that mediate vesicle transport are also important for endochondral ossification. Giantin, encoded by the Golgb1 gene, is a tethering factor for coatomer 1 (COPI) vesicles and functions in the cis-medial Golgi compartments. An insertion mutation in the Golgb1 gene, resulting in a lack of giantin protein expression, has been detected in ocd/ocd rats that exhibit a pleiotropic phenotype including osteochondrodysplasia. To reveal the function of giantin in chondrogenesis, the present study assessed the effects of loss of giantin expression on cartilage ECM and Golgi morphology. Giantin was expressed in normal, but not in ocd/ocd, chondrocytes in the epiphyseal areas of embryonic femurs, whereas GM130 was expressed in both normal and ocd/ocd chondrocytes. The staining intensities of safranin O and azan (aniline blue) were reduced and enhanced, respectively, in epiphyseal cartilage of ocd/ocd femurs. Immunostaining showed that levels of type II collagen and fibronectin were comparable in normal and ocd/ocd cartilage. Levels of type XI collagen were higher, while levels of aggrecan, link protein and hyaluronan were lower, in ocd/ocd than in normal cartilage, although semi-quantitative RT-PCR showed similar levels of type XI collagen, aggrecan and link protein mRNAs in normal and ocd/ocd cartilage. Isolated chondrocytes of ocd/ocd and normal rats showed similar immunostaining patterns for cis-, medial-, and trans-Golgi marker proteins, whereas monolayers of ocd/ocd chondrocytes showed reduced levels of aggrecan and link protein and increased level of type XI collagen in spite of similar transcripts levels. These findings suggest that giantin plays a pivotal role in coordinated production of aggrecan, link protein and type XI collagen in chondrocytes, and that loss of giantin causes osteochondrodysplasia with disturbance of these ECM components. PMID- 29577905 TI - Conditional reprogrammed human limbal epithelial cells represent a novel in vitro cell model for drug responses. AB - In this study, we established human limbal epithelial cells (LECs) from normal limbal tissues by using Conditional Reprogramming (CR) technology (refer to CR LEC cells in this study). We have successfully established CR-LEC cell strains from three human donors (3 out of 3), and normal rabbits (2 out of 2) and pig (1 out of 1) as well. CR-LEC cells sustained a continuous and stable proliferation status with a normal karyotype, normal response to DNA damage, well-defined structured spheres in matrigel 3D culture. Responses of CR-LEC cells to IFN alpha2b, Ganciclovir and 5-Fluorouracil were different, suggesting that these drugs had different toxicities to these cells as expected. More important, there was no significant difference of responses to drugs between early and late passages of CR-LEC cells (p>0.05), indicating CR-LEC cells can serve a stable normal human cell model for toxicity assessment. Toxicity tests with monolayer cultures of CR-LEC cells were measured by staining the F-actin and Dsg-1 expression. Toxicity of three drugs at LD50 concentration resulted in a gradually increased destruction of monolayer, which is, in accordance with the irritation grade of three drugs on human cornea epithelium. Therefore, CR-LEC cells provide a novel and reliable in vitro physiological cell model for corneal toxicity assessment. PMID- 29577906 TI - Soy undecapeptide induces Drosophila hind leg grooming via dopamine receptor. AB - beta-Conglycinin alpha subunit (323-333) [betaCGalpha(323-333)] is an exogenous neuromodulating undecapeptide found from enzymatic digest of beta-conglycinin, a soy major storage protein by mice behavior tests. We investigated effect of betaCGalpha(323-333) on Drosophila behavior. Oral administration of betaCGalpha(323-333) in Drosophila increased hind leg grooming, which may act through specific sets of neurons. It was reported that dopamine receptor (DopR) meditates hind leg grooming, and we tested involvement of DopR in betaCGalpha(323 333)-induced hind leg grooming by using DopR knockout flies. In the wild type but not in the DopR-knockout flies, betaCGalpha(323-333) increased hind leg grooming. These results suggest that betaCGalpha(323-333) induces hind leg grooming via activating the DopR. This is the first report showing that exogenously administered peptide changes fly behaviors. PMID- 29577907 TI - Possible role of ginsenoside Rb1 in skin wound healing via regulating senescent skin dermal fibroblast. AB - Cellular senescence suppresses cancer by inducing irreversible cell growth arrest. Nevertheless, senescent cells is proposed as causal link with aging and aging-related pathologies. The physiological beneficial functions of senescent cells are still of paucity. Here we show that senescent human dermal fibroblast accelerates keratinocytes scratch wound healing and stimulates differentiation of fibroblast. Using oxidative stress (100 MUM H2O2 exposure for 1 h) induction, we successfully triggered fibroblast senescence and developed senescence associated secretory phenotype (SASP). The induction of SASP was regulated by p38MAPK/MSK2/NF-kappaB pathway. Interestingly, inhibition of p38MAPK activation only partially suppressed SASP. However, SASP was significantly inhibited by SB747651A, a specific MSK inhibitor. Additionally, we demonstrate that SASP stimulates migration of keratinocytes and myofibroblast transition of fibroblast, through fold-increased secretion of growth factors, platelet-derived growth factor AA (PDGF-AA) and AB (PDGF-AB), transforming growth factor beta 1 (TGF beta1) and beta 2 (TGF-beta2), vascular endothelial growth factor A (VEGF-A) and D (VEGF-D), vascular endothelial growth factor receptor 2 (VEGFR2) and 3 (VEGFR3). Importantly, we also confirmed ginsenoside Rb1 promoted SASP-mediated healing process via p38MAPK/MSK2/NF-kappaB pathway. The results pointed to senescent fibroblast as a potential mechanism of wound healing control in human skin. Further, it provided a candidate targeted for wound therapy. PMID- 29577908 TI - Promoter-associated proteins of EPAS1 identified by enChIP-MS - A putative role of HDX as a negative regulator. AB - Presence of perivascular neuroblastoma cells with high expression of hypoxia inducible factor (HIF)-2alpha correlates with distant metastasis and aggressive disease. Regulation of HIFs are traditionally considered to occur post translationally, but we have recently shown that HIF-2alpha is unconventionally regulated also at the transcriptional level in neuroblastoma cells. Regulatory factors binding directly to EPAS1 (encoding HIF-2alpha) to promote transcription are yet to be defined. Here, we employ the novel CRISPR/Cas9-based engineered DNA binding molecule-mediated chromatin immunoprecipitation (enChIP) - mass spectrometry (MS) methodology to, in an unbiased fashion, identify proteins that associate with the EPAS1 promoter under normoxic and hypoxic conditions. Our enChIP analysis resulted in 27 proteins binding to the EPAS1 promoter in neuroblastoma cells. In agreement with a general hypoxia-driven downregulation of gene transcription, the majority (24 out of 27) of proteins dissociate from the promoter at hypoxia. Among them were several nucleosome-associated proteins suggesting a general opening of chromatin as one explanation to induced EPAS1 transcription at hypoxia. Of particular interest from the list of released factors at hypoxia was the highly divergent homeobox (HDX) transcription factor, that we show inversely correlates with HIF-2alpha in neuroblastoma cells. We propose a putative model where HDX negatively regulates EPAS1 expression through a release-of-inhibition mechanism. PMID- 29577909 TI - Genome-wide identification and expression analysis of the fatty acid desaturase genes in Medicago truncatula. AB - Fatty acid desaturases (FADs) are of great importance and play critical roles in regulating plant fatty acid (FA) compositions. But to date, no reports about characterization of the FAD genes have been reported in the model dicotyledonous grass species Medicago truncatula. In this study, using database searches, 20 full-length FAD genes were identified in M. truncatula. These FAD genes were unevenly distributed on six chromosomes except the chromosome 6 and 8. Phylogenetic analysis showed the FAD genes in M. truncatula were clustered into six subfamilies and had similar exon number and intron phase in the same subfamily. Moreover, expression analysis based on qRT-PCR indicated these FAD genes were extensively involved in cold and heat responses. This study would provide an important foundation for future cloning and functional studies of FAD genes in M. truncatula and other related legume species. PMID- 29577910 TI - Blood Is Thicker: Hyperviscosity Syndrome. PMID- 29577911 TI - Long non coding RNA XIST as a prognostic cancer marker - A meta-analysis. AB - BACKGROUND: The X inactivate-specific transcript (XIST), derived from XIST gene, is aberrantly expressed in various cancers. High-expression of XIST is related to poor clinical outcome. This meta-analysis evaluated the potential role of XIST as novel predictor of prognosis in human cancer. MATERIALS AND METHODS: This meta analysis collected eligible studies about XIST and tumor prognosis through retrieving keywords in Web of Science, PubMed, Embase and the CNKI database, from 1993 to August 21, 2017. The quantitative meta-analysis was carried out with Stata SE12.0 and RevMan3.23 software. The aim was to determine whether XIST expression is associated with cancer prognosis and clinicopathology. RESULTS: A total of 858 patients from 10 eligible studies were included in the final meta analysis. Overall, a significant negative association between XIST and overall survival (OS) time (HR = 2.62, 95% CI: 2.18-3.14) was observed. Statistical significance was also showed in subgroup meta-analysis stratified by the country, sample size, follow-up and publication year. It was reported that increased XIST was positively related to advanced clinical TNM stage (OR = 4.03, 95% CI: 2.22 7.30), lymph node metastasis (LNM) (OR = 2.70, 95% CI: 1.73-4.21), distant metastasis (DM) (OR = 2.61, 95% CI: 1.57-4.33) and tumor size (OR = 3.10, 95% CI: 2.24-4.30). CONCLUSIONS: LncRNA XIST may serve as a potential biomarker to predict solid tumor prognosis. This molecule can be effectively used to predict the clinical and pathological features of cancers.

PMID- 29577913 TI - Reference limits of the urinary gamma-glutamyltransferase in a healthy population and effects of short-term storage on the enzyme activity. AB - BACKGROUND: Gamma-glutamyltransferase (GGT) is present mainly in proximal renal tubule, and urinary GGT is an indicator of tubular damage since it may show renal changes before they are identified by using conventional measurements. Therefore, it is of interest to establish the reference limits of urinary GGT for a healthy population, as well as to investigate the stability of GGT in urine samples stored at 4 degrees C and -20 degrees C. METHODS: GGT was assessed in urine samples from 127 healthy patients by use of a reference method based on the 5 Amino-2-Nitrobenzoate formation. Stability of GGT was evaluated in 10 urine samples stored at temperatures of 4 degrees C and -20 degrees C for a period up to 4 weeks. RESULTS: Urinary GGT values for healthy volunteers were 14 U/g creatinine for the lower reference limit and 79 U/g creatinine for the upper reference limit. Urinary GGT values were approximately 56% lower in samples stored at -20 degrees C than fresh samples, while samples stored at 4 degrees C presented a decrease of 11% in GGT values compared to fresh samples. CONCLUSIONS: Reference limits for urinary GGT in healthy subjects were 14 to 79 U/g creatinine, and it is recommended to measure urinary GGT in fresh specimens. PMID- 29577914 TI - The importance of the learning process in ST analysis interpretation and its impact in improving clinical and neonatal outcomes. AB - BACKGROUND: Intrapartum fetal heart rate monitoring was introduced with the goal to reduce fetal hypoxia and deaths. However, continuous fetal heart rate monitoring has been shown to have a high sensitivity but also a high false positive rate. To improve specificity, adjunctive technologies have been developed to identify fetuses at risk for intrapartum asphyxia. Intensive research on the value of ST-segment analysis of the fetal electrocardiogram as an adjunct to standard electronic fetal monitoring in lowering the rates of fetal metabolic acidosis and operative deliveries has been ongoing. The conflicting results in randomized and observational studies may partly be due to differences in study design. OBJECTIVE: This study aims to determine the significance of the learning process for the introduction of ST analysis into clinical practice and its impact on initial and subsequent obstetric outcomes. STUDY DESIGN: This was a prospective observational study with the primary objective to evaluate the importance of the learning period on the rates of metabolic acidosis and operative deliveries after the implementation of ST analysis. The study was conducted at the Turku University Hospital, Turku, Finland, with 3400-4200 annual deliveries. The whole study population consisted of all 42,146 deliveries during the study period 2001 through 2011. The ST analysis usage rate was 18%. The data were collected prospectively from labors monitored with ST analysis as an adjunct to conventional intrapartum fetal heart rate monitoring. Primary endpoints were the rates of metabolic acidosis (cord artery pH <7.05 and an extracellular fluid compartment base deficit >12.0 mmol/L), fetal scalp blood sampling, and operative deliveries. Comparisons of these outcomes were made between the initiation period (the first 2 years) and the subsequent usage period (the next 9 years). RESULTS: In the whole study population the prevalence of cord pH <7.05 decreased from 1.5 0.81% (relative risk, 0.54; 95% confidence interval, 0.43-0.67), the rate of cesarean deliveries from 17.2-14.1% (relative risk, 0.82; 95% confidence interval, 0.89-0.97), and the rate of fetal scalp blood sampling from 1.75-0.82% (relative risk, 0.47; 95% confidence interval, 0.38-0.58) when the 2 study periods were compared. In the ST analysis group, the frequency of cord metabolic acidosis rate was reduced from 1.0-0.25% (relative risk, 0.33; 95% confidence interval, 0.15-0.72). CONCLUSION: We provide evidence that the results improve over time and there is a learning curve in the introduction of the ST analysis method. This was demonstrated by the lower rates of metabolic acidosis and operative deliveries after the initial implementation period. PMID- 29577915 TI - Training contraceptive providers to offer intrauterine devices and implants in contraceptive care: a cluster randomized trial. AB - BACKGROUND: US unintended pregnancy rates remain high, and contraceptive providers are not universally trained to offer intrauterine devices and implants to women who wish to use these methods. OBJECTIVE: We sought to measure the impact of a provider training intervention on integration of intrauterine devices and implants into contraceptive care. STUDY DESIGN: We measured the impact of a continuing medical education-accredited provider training intervention on provider attitudes, knowledge, and practices in a cluster randomized trial in 40 US health centers from 2011 through 2013. Twenty clinics were randomly assigned to the intervention arm; 20 offered routine care. Clinic staff participated in baseline and 1-year surveys assessing intrauterine device and implant knowledge, attitudes, and practices. We used a difference-in-differences approach to compare changes that occurred in the intervention sites to changes in the control sites 1 year later. Prespecified outcome measures included: knowledge of patient eligibility for intrauterine devices and implants; attitudes about method safety; and counseling practices. We used multivariable regression with generalized estimating equations to account for clustering by clinic to examine intervention effects on provider outcomes 1 year later. RESULTS: Overall, we surveyed 576 clinic staff (314 intervention, 262 control) at baseline and/or 1-year follow-up. The change in proportion of providers who believed that the intrauterine device was safe was greater in intervention (60% at baseline to 76% at follow-up) than control sites (66% at both times) (adjusted odds ratio, 2.48; 95% confidence interval, 1.13-5.4). Likewise, for the implant, the proportion increased from 57 77% in intervention, compared to 61-65% in control sites (adjusted odds ratio, 2.57; 95% confidence interval, 1.44-4.59). The proportion of providers who believed they were experienced to counsel on intrauterine devices also increased in intervention (53-67%) and remained the same in control sites (60%) (adjusted odds ratio, 1.89; 95% confidence interval, 1.04-3.44), and for the implant increased more in intervention (41-62%) compared to control sites (48-50%) (adjusted odds ratio, 2.30; 95% confidence interval, 1.28-4.12). Knowledge scores of patient eligibility for intrauterine devices increased at intervention sites (from 0.77-0.86) 6% more over time compared to control sites (from 0.78-0.80) (adjusted coefficient, 0.058; 95% confidence interval, 0.003-0.113). Knowledge scores of eligibility for intrauterine device and implant use with common medical conditions increased 15% more in intervention (0.65-0.79) compared to control sites (0.67-0.66) (adjusted coefficient, 0.15; 95% confidence interval, 0.09 0.21). Routine discussion of intrauterine devices and implants by providers in intervention sites increased significantly, 71-87%, compared to in control sites, 76-82% (adjusted odds ratio, 1.97; 95% confidence interval, 1.02-3.80). CONCLUSION: Professional guidelines encourage intrauterine device and implant competency for all contraceptive care providers. Integrating these methods into routine care is important for access. This replicable training intervention translating evidence into care had a sustained impact on provider attitudes, knowledge, and counseling practices, demonstrating significant changes in clinical care a full year after the training intervention. PMID- 29577916 TI - Prevention of obesity and diabetes in pregnancy: is it an impossible dream? AB - The obesity and diabetes epidemic is an unintended consequence of economic, social, and technological changes. In nonpregnancy, people identified as high risk to develop type 2 diabetes may delay progression by 30-70% with lifestyle interventions and pharmacological agents. In pregnancy, lifestyle interventions have been the primary focus to prevent fetal short- and long-term complications that may evolve into substantial weight gain and gestational diabetes mellitus. The dilemma for obstetricians is whether diabetes and obesity can be prevented and not simply treated after the fact. Interventions after women become pregnant may be too late to see the kinds of meaningful improvements in child and maternal health because there is a short interval from gestational diabetes mellitus diagnosis to delivery. Therefore, future efforts need to incorporate quality research, lifestyle interventions that designate time of initiation and duration during pregnancy, the preventative intervention of a prepregnant "fourth trimester," coupled with the concept of precision medicine so that there is the potential to make the impossible dream a reality.

PMID- 29577919 TI - Evaluation of sPGA * BSA as an Outcome Measure and Treatment Target for Clinical Practice. AB - Clinical outcome measures are becoming more important in psoriasis treatment. Reliable and standardized measures of severity feasible for clinical practice are needed. Our objective was to investigate body surface area (BSA) and the product of BSA and static Physician Global Assessment (sPGA) (ie, BSA * sPGA) as potential proxy measures for PASI scores. Data were pooled from three multicenter, randomized, double-blind, placebo-controlled, phase 3 trials of ixekizumab in patients with moderate to severe psoriasis (UNCOVER-1, -2, -3; N = 3,866). Assessments included the Psoriasis Area and Severity Index (PASI), BSA, and BSA * sPGA. Rank correlations between BSA * sPGA and PASI were stronger than between BSA and PASI (baseline, r = 0.759 vs. r = 0.707; week 12, r = 0.959 vs. r = 0.924). Week 12 concordance rates with PASI responses were as follows: for 75% reduction in PASI: BSA, 86.2%; BSA * sPGA, 93.8%; for 90% reduction in PASI: BSA, 86.9%; BSA * sPGA, 88.2%. The 75% reduction in PASI positive and negative predictive values were higher for BSA * sPGA versus BSA; for 90% reduction in PASI, positive predictive value was lower and negative predictive value was higher for BSA * sPGA versus BSA. Receiver operating characteristic curve analyses identified the most accurate percentage changes in BSA and BSA * sPGA as 66% and 83% for a 75% reduction in PASI cutoff and 84% and 94% for a 90% reduction in PASI, respectively. These results suggest that BSA and BSA * sPGA are viable tools for use as a PASI proxy by real-world practitioners and may be appropriate measurements for use in clinical practice for treat-to-target strategies. PMID- 29577917 TI - Msx2 Supports Epidermal Competency during Wound-Induced Hair Follicle Neogenesis. AB - Cutaneous wounds in adult mammals typically heal by scarring. However, large full thickness wounds undergo wound-induced hair follicle neogenesis (WIHN), a form of regeneration. Here, we show that WIHN requires transient expression of epidermal Msx2 in two phases: the wound margin early and the wound center late. Msx2 expression is present in the migrating epithelium during early wound healing and then presents in the epithelium and mesenchyme later in the wound center. WIHN is abrogated in germline and epithelial-specific Msx2 mutant mice. Unlike the full length Msx2 promoter, a minimal Msx2 promoter fails activation in the wound center, suggesting complex regulation of Msx2 expression. The Msx2 promoter binding sites include Tcf/Lef, Jun/Creb, Pax3, and three SMAD sites. However, basal epithelial-induced BMP suppression by noggin overexpression did not affect WIHN. We propose that Msx2 signaling is required for the epidermis to acquire spatiotemporal competence during WIHN. Topologically, hair regeneration dominates in the wound center, coinciding with late Msx2 expression. Together, these results suggest that intrinsic Msx2 expression supports epithelial competency during hair follicle neogenesis. This work provides insight into endogenous mechanisms modulating competency of adult epidermal progenitors for mammalian ectodermal appendage neogenesis, and offers the target Msx2 for future regeneration-promoting therapies. PMID- 29577920 TI - IL-21 Attenuates FITC-Induced Contact Hypersensitivity Response via Regulation of Dendritic Cell Function. AB - IL-21 is mainly produced by activated CD4+ T cells and is involved in the activation of immune cells such as T cells and macrophages. In contrast, IL-21 suppresses dendritic cell maturation. We studied the effect of IL-21 in a mouse model of FITC-induced contact hypersensitivity using IL-21 isoform transgenic (IL 21iso-Tg) mice. Tissue inflammation at 24 hours after elicitation in IL-21iso-Tg mice was significantly weaker than that in wild-type mice. In agreement with tissue inflammation, recruitment of CD4+ and CD8+ T cells, neutrophils, and macrophages into the inflamed tissue was decreased in IL-21iso-Tg mice. In addition, both mRNA expression and protein production of inflammatory cytokines were lower in IL-21iso-Tg mice. In the skin, T cells were activated at inducible skin-associated lymphoid tissue, which is likely a gut-associated lymphoid tissue. The mRNA level of CXCL2, an essential chemokine for inducible skin associated lymphoid tissue formation, was significantly lower in IL-21iso-Tg mice, and histological analysis showed that dendritic cell clustering, a preliminary step in inducible skin-associated lymphoid tissue formation, was impaired. Our study showed that IL-21 down-regulated inducible skin-associated lymphoid tissue formation and reduced contact hypersensitivity response.

AB - BACKGROUND: Traditionally, wire cerclage has been used to reapproximate the sternum after sternotomy. Recent evidence suggests that rigid plate fixation for sternal closure may reduce the risk of sternal complications. METHODS: The Medline and Embase databases were searched from inception to February 2017 for studies that compared rigid plate fixation with wire cerclage for cardiac surgery patients undergoing sternotomy. Random effects meta-analysis compared rates of sternal complications (primary outcome, defined as deep or superficial sternal wound infection, or sternal instability), early mortality, and length of stay (secondary outcomes). RESULTS: Three randomized controlled trials (n = 427) and five unadjusted observational studies (n = 1,025) met inclusion criteria. There was no significant difference in sternal complications with rigid plate fixation at a median of 6 months' follow-up (incidence rate ratio 0.51, 95% confidence interval [CI]: 0.20 to 1.29, p = 0.15) overall, but a decrease when including only patients at high risk for sternal complications (incidence rate ratio 0.23, 95% CI: 0.06 to 0.89, p = 0.03; two observational studies). Perioperative mortality was reduced favoring rigid plate fixation (relative risk 0.40, 95% CI: 0.28 to 0.97, p = 0.04; four observational studies and one randomized controlled trial). Length of stay was similar overall (mean difference -0.77 days, 95% CI: 1.65 to +0.12, p = 0.09), but significantly reduced with rigid plate fixation in the observational studies (mean difference -1.34 days, 95% CI: -2.05 to -0.63, p = 0.0002). CONCLUSIONS: This meta-analysis, driven by the results of unmatched observational studies, suggests that rigid plate fixation may lead to reduced sternal complications in patients at high risk for such events, improved perioperative survival, and decreased hospital length of stay. More randomized controlled trials are required to confirm the potential benefits of rigid plate fixation for primary sternotomy closure. PMID- 29577922 TI - Efficacy and Cost of Awake Thoracoscopy and Video-Assisted Thoracoscopic Surgery in the Undiagnosed Pleural Effusion. AB - BACKGROUND: The study aim is to compare the diagnostic yield, safety, and cost of outpatient awake thoracoscopy (AT) with video-assisted thoracoscopic surgery (VATS) pleural biopsy in undiagnosed pleural effusions. METHODS: The diagnostic yield of pleural biopsy performed by AT or VATS in patients with undiagnosed exudative pleural effusions at a tertiary thoracic surgery center in Canada between 2011 and 2015 was retrospectively evaluated. Test sensitivity, specificity, positive predictive value, and negative predictive value were compared. Procedure safety, hospital length of stay, additional pleural-based interventions, and procedure-related costs were compared. RESULTS: Patients underwent either AT (n = 78) or VATS (n = 99) during the study period. Sensitivity, specificity, positive predictive value, and negative predictive value were 85%, 100%, 100%, and 79% for AT and 93%, 94%, 99%, and 76% for VATS, with no significant difference in diagnostic test performance. There was no difference in the rate of major complications (2 AT [2.6%] versus 4 VATS [4.0%], p = 0.696), minor complications (14 AT [17.9%] versus 16 VATS [16.2%], p = 0.841) or need for additional pleural-based procedures (20 AT [25.6%] versus 18 VATS [18.2%], p = 0.270). The VATS was associated with longer median hospital stay (VATS 3 days [interquartile range: 1 to 4] versus AT 0 days [interquartile range: 0 to 1], z = 6.98, p < 0.001) and a higher procedure-related average cost (VATS Canadian dollars $7,962 [95% confidence interval: $7,134 to $8,790] versus AT Canadian dollars $2,815 [95% confidence interval: $2,010 to $3,620], p < 0.001). CONCLUSIONS: Awake thoracoscopy and VATS have similar diagnostic yield and safety profiles in the assessment of undiagnosed pleural effusions; however, AT is associated with shorter length of stay and lower average per-procedure cost. In the appropriate clinical setting, AT may be the diagnostic test of choice. PMID- 29577923 TI - Arteriovenous Malformation Presenting as an Infiltrating Mass of the Right Ventricle. PMID- 29577924 TI - The Society of Thoracic Surgeons 2018 Adult Cardiac Surgery Risk Models: Part 2 Statistical Methods and Results. AB - BACKGROUND: The Society of Thoracic Surgeons (STS) uses statistical models to create risk-adjusted performance metrics for Adult Cardiac Surgery Database (ACSD) participants. Because of temporal changes in patient characteristics and outcomes, evolution of surgical practice, and additional risk factors available in recent ACSD versions, completely new risk models have been developed. METHODS: Using July 2011 to June 2014 ACSD data, risk models were developed for operative mortality, stroke, renal failure, prolonged ventilation, mediastinitis/deep sternal wound infection, reoperation, major morbidity or mortality composite, prolonged postoperative length of stay, and short postoperative length of stay among patients who underwent isolated coronary artery bypass grafting surgery (n = 439,092), aortic or mitral valve surgery (n = 150,150), or combined valve plus coronary artery bypass grafting surgery (n = 81,588). Separate models were developed for each procedure and endpoint except mediastinitis/deep sternal wound infection, which was analyzed in a combined model because of its infrequency. A surgeon panel selected predictors by assessing model performance and clinical face validity of full and progressively more parsimonious models. The ACSD data (July 2014 to December 2016) were used to assess model calibration and to compare discrimination with previous STS risk models. RESULTS: Calibration in the validation sample was excellent for all models except mediastinitis/deep sternal wound infection, which slightly underestimated risk and will be recalibrated in feedback reports. The c-indices of new models exceeded those of the last published STS models for all populations and endpoints except stroke in valve patients. CONCLUSIONS: New STS ACSD risk models have generally excellent calibration and discrimination and are well suited for risk adjustment of STS performance metrics. PMID- 29577925 TI - The Society of Thoracic Surgeons 2018 Adult Cardiac Surgery Risk Models: Part 1 Background, Design Considerations, and Model Development. AB - BACKGROUND: The last published version of The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) risk models were developed in 2008 based on patient data from 2002 to 2006 and have been periodically recalibrated. In response to evolving changes in patient characteristics, risk profiles, surgical practice, and outcomes, the STS has now developed a set of entirely new risk models for adult cardiac surgery. METHODS: New models were estimated for isolated coronary artery bypass grafting surgery (CABG [n = 439,092]), isolated aortic or mitral valve surgery (n = 150,150), and combined valve plus CABG procedures (n = 81,588). The development set was based on July 2011 to June 2014 STS ACSD data; validation was performed using July 2014 to December 2016 data. Separate models were developed for operative mortality, stroke, renal failure, prolonged ventilation, reoperation, composite major morbidity or mortality, and prolonged or short postoperative length of stay. Because of its low occurrence rate, a combined model incorporating all operative types was developed for deep sternal wound infection/mediastinitis. RESULTS: Calibration was excellent except for the deep sternal wound infection/mediastinitis model, which slightly underestimated risk because of higher rates of this endpoint in the more recent validation data; this will be recalibrated in each feedback report. Discrimination (c-index) of all models was superior to that of 2008 models except for the stroke model for valve patients. CONCLUSIONS: Completely new STS ACSD risk models have been developed based on contemporary patient data; their performance is superior to that of previous STS ACSD models. PMID- 29577926 TI - Type A Aortic Dissection After the Ross Procedure. AB - We describe a case of type A aortic dissection in a 25-year-old woman who had undergone a Ross procedure for aortic valve endocarditis 13 years previously. She was pregnant and noted to have significant enlargement of the aortic root during the latter portion of the third trimester of her pregnancy. An echocardiogram after delivery demonstrated new aortic valve insufficiency in addition to an aortic root diameter of 6.5 cm. A computed tomography angiogram demonstrated a type A aortic dissection involving only the very proximal portion of the ascending aorta. At operation, the dissection was found to be limited to the pulmonary autograft. This was repaired using a valve-sparing technique. Her postoperative course was uneventful, and the aortic valve has shown only trace insufficiency at 3 years of follow-up. PMID- 29577927 TI - Influence of Diabetes Mellitus on Outcomes in Patients After Left Ventricular Assist Device Implantation. AB - BACKGROUND: Despite previous studies, the mortality risk of patients with diabetes mellitus after left ventricular assist device (LVAD) implant remains unclear. In addition, the relationship between the degree of glycemic control and long-term mortality risk in LVAD patients with diabetes has not been established. METHODS: Ninety-five nondiabetic patients and 96 diabetic patients from the University of Rochester Medical Center who received a HeartMate II (Thoratec, Pleasanton, CA) continuous-flow LVAD between May 2008 and June 2014 were included in this study. The primary outcome was all-cause mortality. Secondary outcomes included rates of infection, neurologic dysfunction, renal dysfunction, and rehospitalization. Kaplan-Meier survival analyses and Cox models were utilized. RESULTS: During follow-up, 32 diabetic patients (33%) and 15 nondiabetic patients (16%) died after LVAD implantation. Cumulative probability of death was higher for diabetic patients when compared with nondiabetic patients (42% versus 21% at 3 years, p = 0.013). There were no significant differences in overall rates of infection, neurologic dysfunction, and rehospitalization between the two groups. However, after an initial secondary outcome event, diabetic patients continued to have a higher mortality rate when compared with nondiabetic patients. There was no statistically significant difference in the risk of death between diabetic patients with pre-LVAD hemoglobin A1c less than 7.0% and diabetic patients with pre-LVAD hemoglobin A1c 7.0% or greater (hazard ratio 1.71, 95% confidence interval: 0.72 to 4.08, p = 0.223). CONCLUSIONS: Diabetic patients who underwent LVAD implantation had a higher risk of death compared with nondiabetic patients. Adverse event rates did not differ between the two groups. Finally, the degree of glycemic control in diabetic patients before LVAD was not found to influence mortality. PMID- 29577928 TI - Pleural Coating by 50% Glucose Solution Reduces Postoperative Recurrence of Spontaneous Pneumothorax. AB - BACKGROUND: Video-assisted thoracoscopic surgery is the standard procedure for treatment of spontaneous pneumothorax. However, postoperative recurrence is relatively common even if an absorbable covering sheet is used for reinforcement of the visceral pleura. Injection of a high concentration glucose solution to the thoracic cavity was recently reported to be effective in stopping postoperative air leakage or as a prophylactic procedure to prevent postoperative recurrence of spontaneous pneumothorax. Therefore, we used 50 mL of a 50% glucose solution for pleural coating (GPC) on an absorbable sheet intraoperatively to prevent postoperative recurrence of spontaneous pneumothorax. This is a retrospective study, and patient backgrounds are heterogeneous. We evaluated the feasibility of GPC using propensity scores to adjust for heterogeneity in their backgrounds. METHODS: Between January 2010 and December 2017, 376 patients who underwent video assisted thoracoscopic surgery, with or without GPC, were evaluated. The GPC group consisted of 106 patients, and the non-GPC group consisted of 270. We analyzed the factors preventing postoperative recurrence of spontaneous pneumothorax by univariate analysis and Cox regression analysis with or without propensity score matching. RESULTS: Univariate analysis revealed age of 25 or older, smoking habit, no history of an ipsilateral operation, and GPC were significant factors preventing postoperative recurrence. GPC significantly prevented postoperative recurrence as shown by Cox regression analysis with propensity score matching (hazard ratio, 0.15; p = 0.014) and the inverse probability of treatment weighted method (hazard ratio, 0.23; p = 0.0038). CONCLUSIONS: Intraoperative GPC significantly reduced the postoperative recurrence rate of spontaneous pneumothorax. PMID- 29577929 TI - Giant Cell Tumor of Bone Presenting as Left Posteromedial Chest Wall Tumor. AB - Giant cell tumor is a relatively uncommon bone tumor rarely originating from the chest wall. Given its proximity to vital structures in the thoracic cavity, treatment options may be challenging. We report the case of a patient with a giant cell tumor of the posterolateral chest wall with invasion of the thoracic spine treated with neoadjuvant denosumab, followed by surgical resection. PMID- 29577930 TI - Need for Permanent Pacemaker After Surgical Aortic Valve Replacement Reduces Long Term Survival. AB - BACKGROUND: Permanent pacemaker (PPM) implantation has been touted as an inconsequential complication after transcatheter aortic valve replacement. As transcatheter aortic valve replacement moves to lower risk patients, the long term implications remain poorly understood; therefore, we evaluated the long-term outcomes of pacemaker for surgical aortic valve replacement patients. METHODS: A total of 2,600 consecutive patients undergoing surgical aortic valve replacement over the past 15 years were reviewed using The Society of Thoracic Surgeons (STS) institutional database and Social Security death records. Patients were stratified by placement of a PPM within 30 days of surgery. The impact of PPM placement on long-term survival was assessed by Kaplan-Meier analysis and risk adjusted survival by Cox proportional hazards modeling. RESULTS: A total of 72 patients (2.7%) required PPM placement postoperatively. Patients requiring PPM had more postoperative complications, including atrial fibrillation (43.1% versus 27.0%, p = 0.003), prolonged ventilation (16.7% versus 5.7%, p < 0.0001), and renal failure (12.5% versus 4.6%, p = 0.002). These led to greater resource utilization including longer intensive care unit stay (89 versus 44 hours, p < 0.0001) and hospital length of stay (9 versus 6 days, p < 0.0001), and higher inflation-adjusted hospital cost ($81,000 versus $47,000, p < 0.0001). Median follow-up was 7.5 years, and patients requiring PPM had significantly worse long term survival (p = 0.02), even after risk adjustment with STS predicted risk of mortality (hazard ratio 1.48, p = 0.02). CONCLUSIONS: The need for PPM after aortic valve replacement independently reduces long-term survival. The rate of PPM placement after surgical aortic valve replacement remains very low but dramatically increases resource utilization. As transcatheter aortic valve replacement expands to low-risk patients, the impact of PPM placement on long term survival warrants close monitoring.

PMID- 29577932 TI - Looking for the right mate in diploid species: How does genetic dominance affect the spatial differentiation of a sexual trait? AB - Divergence between populations for a given trait can be driven by sexual selection, interacting with migration behaviour. Mating preference for different phenotypes may lead to specific migration behaviour, with departures from populations where the preferred trait is rare. Such preferences can then trigger the emergence and persistence of differentiated populations, even without any local adaptation. However the genetic architecture underlying the trait targeted by mating preference may have a profound impact on population divergence. In particular, dominance between alleles encoding for divergent phenotypes can interfere with the differentiation process. Using a diploid model of a trait determining both mating success and migration rate, we explored differentiation between two connected populations, assuming either co-dominance or strict dominance between alleles. The model assumes that individuals prefer mating with partners displaying the same phenotype and therefore tend to move to the other population when their own phenotype is rare. We show that the emergence of differentiated populations in this diploid moded is limited as compared to results obtained with the same model assuming haploidy. When assuming co dominance, differentiation arises only when migration is limited compared to the strength of the preference. Such differentiation is less dependent on migration when assuming strict dominance between haplotypes. Dominant alleles frequently invade populations because their phenotype is more frequently expressed, resulting in higher local mating success and a rapid decrease in migration. However, depending on the initial distribution of alleles, this advantage associated with dominance (i.e. Haldane's sieve) may lead to fixation of the dominant allele throughout both populations. Depending on the initial distribution of heterozygotes in the two populations, persistence of polymorphisms within populations can also occur because heterozygotes displaying the predominant phenotype benefit from high mating success. Altogether, our results highlight that heterozygotes' behaviour has a strong impact on population differentiation and highlight the need for diploid models of differentiation and speciation driven by sexual selection. PMID- 29577934 TI - Selective Spatiotemporal Vulnerability of Central Nervous System Neurons to Pathologic TAR DNA-Binding Protein 43 in Aged Transgenic Mice. AB - Amyotrophic lateral sclerosis (ALS) is a rapidly progressing and fatal disease characterized by muscular atrophy because of loss of upper and lower motor neurons. Histopathologically, most patients with ALS have abnormal cytoplasmic accumulation and aggregation of the nuclear RNA-regulating protein TAR DNA binding protein 43 (TDP-43). Pathogenic mutations in the TARDBP gene that encode TDP-43 have been identified in familial ALS. We have previously reported transgenic mice with neuronal expression of human TDP-43 carrying the pathogenic A315T mutation (iTDP-43A315T mice), presenting with early-onset motor deficits in adolescent animals. Here, we analyzed aged iTDP-43A315T mice, focusing on the spatiotemporal profile and progression of neurodegeneration in upper and lower motor neurons. Magnetic resonance imaging and histologic analysis revealed a differential loss of upper motor neurons in a hierarchical order as iTDP-43A315T mice aged. Furthermore, we report progressive gait problems, profound motor deficits, and muscle atrophy in aged iTDP-43A315T mice. Despite these deficits and TDP-43 pathologic disorders in lower motor neurons, stereological analysis did not show cell loss in spinal cords. Taken together, neuronal populations in aging iTDP-43A315T mice show differential susceptibility to the expression of human TDP-43A315T. PMID- 29577935 TI - Parathyroid Hormone-Like Hormone Induces Epithelial-to-Mesenchymal Transition of Intestinal Epithelial Cells by Activating the Runt-Related Transcription Factor 2. AB - Epithelial-to-mesenchymal transition (EMT) is a key contributor to fibroblast activation in fibrosis of multiple organs, including the intestine. Parathyroid hormone-like hormone (PTHLH) is an important factor in renal fibrosis and regulates several processes, including EMT. Herein, we investigated the role of PTHLH-induced EMT in intestinal fibrosis associated with Crohn disease. The expression levels of the EMT-related proteins, PTHLH, and parathyroid hormone receptor 1 (PTH1R) in intestinal tissues were determined by immunohistochemistry, and our results revealed that PTHLH and PTH1R were significantly elevated and associated with EMT marker expression. Moreover, neutralizing PTH1R and antagonizing PTHLH bioactivity prevented transforming growth factor-beta1-induced EMT. PTH1R can propagate the protein kinase A (PKA) signal and activate downstream nuclear transcription factors, including runt-related transcription factor 2 (Runx2). In addition, lentiviral vector-PTHLH-treated mice were highly sensitive to 2,4,6-trinitrobenzene sulfonic acid, and analysis of the PTHLH-PTH1R axis revealed the involvement of PKA-Runx2 in PTHLH-induced EMT. Our results indicate that PTHLH triggered EMT in intestinal epithelial cells through the PKA Runx2 pathway, which might serve as a therapeutic target for intestinal fibrosis in Crohn disease. PMID- 29577933 TI - Comprehensive Evaluation of Programmed Death-Ligand 1 Expression in Primary and Metastatic Prostate Cancer. AB - Antibodies targeting the programmed cell death protein 1/programmed death-ligand 1 (PD-L1) interaction have shown clinical activity in multiple cancer types. PD L1 protein expression is a clinically validated predictive biomarker of response for such therapies. Prior studies evaluating the expression of PD-L1 in primary prostate cancers have reported highly variable rates of PD-L1 positivity. In addition, limited data exist on PD-L1 expression in metastatic castrate-resistant prostate cancer (mCRPC). Here, we determined PD-L1 protein expression by immunohistochemistry using a validated PD-L1-specific antibody (SP263) in a large and representative cohort of primary prostate cancers and prostate cancer metastases. The study included 539 primary prostate cancers comprising 508 acinar adenocarcinomas, 24 prostatic duct adenocarcinomas, 7 small-cell carcinomas, and a total of 57 cases of mCRPC. PD-L1 positivity was low in primary acinar adenocarcinoma, with only 7.7% of cases showing detectable PD-L1 staining. Increased levels of PD-L1 expression were noted in 42.9% of small-cell carcinomas. In mCRPC, 31.6% of cases showed PD-L1-specific immunoreactivity. In conclusion, in this comprehensive evaluation of PD-L1 expression in prostate cancer, PD-L1 expression is rare in primary prostate cancers, but increased rates of PD-L1 positivity were observed in mCRPC. These results will be important for the future clinical development of programmed cell death protein 1/PD-L1 targeting therapies in prostate cancer. PMID- 29577936 TI - Possible Involvement of Human Mast Cells in the Establishment of Pregnancy via Killer Cell Ig-Like Receptor 2DL4. AB - The involvement of mast cells in the establishment of pregnancy is unclear. Herein, we found that human mast cells are present in the decidual tissues of parous women and expressed a human-specific protein killer cell Ig-like receptor (KIR) 2DL4, a receptor for human leukocyte antigen G expressed on human trophoblasts. In contrast, decreased numbers of decidual mast cells and reduced KIR2DL4 expression were observed in these cells of infertile women who had undergone long-term corticosteroid treatment. Co-culture of the human mast cell line, LAD2, and human trophoblast cell line, HTR-8/SVneo, accelerated the migration and tube formation of HTR-8/SVneo cells in a KIR2DL4-dependent manner. These observations suggest the possible involvement of human mast cells in the establishment of pregnancy via KIR2DL4 and that long-term corticosteroid treatment may cause infertility by influencing the phenotypes of decidual mast cells. PMID- 29577937 TI - Hepatitis C Virus Mimics Effects of Glypican-3 on CD81 and Promotes Development of Hepatocellular Carcinomas via Activation of Hippo Pathway in Hepatocytes. AB - Glypican (GPC)-3 is overexpressed in hepatocellular carcinomas (HCCs). GPC3 binds to CD81. Forced expression of CD81 in a GPC3-expressing HCC cell line caused activation of Hippo, a decrease in ezrin phosphorylation, and a decrease in yes associated protein (YAP). CD81 is also associated with hepatitis C virus (HCV) entry into hepatocytes. Activation of CD81 by agonistic antibody causes activation of tyrosine-protein kinase SYK (SYK) and phosphorylation of ezrin, a regulator of the Hippo pathway. In cultures of normal hepatocytes, CD81 agonistic antibody led to enhanced phosphorylation of ezrin and an increase in nuclear YAP. HCV E2 protein mimicked GPC3 and led to enhanced Hippo activity and decreased YAP in cultured normal human hepatocytes. HCC tissue microarray revealed a lack of expression of CD81 in most HCCs, rendering them insusceptible to HCV infection. Activation of CD81 by agonistic antibody suppressed the Hippo pathway and increased nuclear YAP. HCV mimicked GPC3, causing Hippo activation and a decrease in YAP. HCV is thus likely to enhance hepatic neoplasia by acting as a promoter of growth of early CD81-negative neoplastic hepatocytes, which are resistant to HCV infection, and thus have a proliferative advantage to clonally expand as they participate in compensatory regeneration for the required maintenance of 100% of liver weight (hepatostat). PMID- 29577938 TI - HS218 as an FXR antagonist suppresses gluconeogenesis by inhibiting FXR binding to PGC-1alpha promoter. AB - INTRODUCTION: Farnesoid X receptor (FXR) as a member of nuclear receptor is tightly associated with glucose metabolism. Accumulated evidence has addressed the potential of FXR antagonist in the treatment of type 2 diabetes mellitus (T2DM), although the related mechanisms remain unclear. Here, we determined a specific FXR antagonist HS218 (N-benzyl-N-(3-(tert-butyl)-4-hydroxyphenyl)-2,4 dichlorobenzamide), which exhibited high activities in suppressing gluconeogenesis and ameliorating glucose homeostasis in db/db and HFD/STZ-induced T2DM mice. We would like to investigate the mechanisms underlying FXR antagonism in the regulation of gluconeogenesis by using HS218 as a probe. METHODS: HS218 was evaluated by glucose output assay. Binding affinity of HS218 to the ligand binding domain of FXR (FXR-LBD) was detected by Surface Plasmon Resonance (SPR) technology-based Biacore and fluorescence quenching assays. Mammalian one-hybrid and transactivation assays were carried out to detect the antagonistic effect of HS218 on FXR. Real-time PCR assay was performed to measure the expressions of FXR target and gluconeogenic genes. Anti-diabetic efficiencies of HS218 were determined in db/db and HFD/STZ-induced T2DM mice. Assays by promoter 5'-deletion analysis and Chromatin immunoprecipitation (ChIP) were performed to detect the binding of FXR to peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha) promoter. Western blot assay was used to determine the protein level in either cells or the liver tissues of mice. RESULTS: We determined that HS218 as a new FXR specific antagonist could FXR-dependently suppress gluconeogenesis in mouse primary hepatocytes, and effectively improve glucose homeostasis in db/db and HFD/STZ-induced T2DM mice. HS218 decreased gluconeogenesis by inhibiting the FXR-induced increase in the promoter activity of the key gluconeogenic gene PGC-1alpha, leading to the repression of PGC-1alpha and its target gene peroxisome proliferator-activated receptor alpha (PPARalpha). CONCLUSIONS: To our knowledge, our work might be the first report on the mechanism underlying FXR antagonist in the regulation of gluconeogenesis, and all results have also highlighted the potential of HS218 in the treatment of T2DM. PMID- 29577939 TI - Trends in vanadium neurotoxicity. AB - Vanadium, atomic number 23, is a transition metal widely distributed in nature. It is a major contaminant of fossil fuels and is widely used in industry as catalysts, in welding, and making steel alloys. Over the years, vanadium compounds have been generating interests due to their use as therapeutic agents in the control of diabetes, tuberculosis, and some neoplasms. However, the toxicity of vanadium compounds is well documented in literature with occupational exposure of workers in vanadium allied industries, environmental pollution from combustion of fossil fuels and industrial exhausts receiving concerns as major sources of toxicity and a likely predisposing factor in the aetiopathogenesis of neurodegenerative diseases. A lot has been done to understand the neurotoxic effects of vanadium, its mechanisms of action and possible antidotes. Sequel to our review of the subject in 2011, this present review is to detail the recent insights gained in vanadium neurotoxicity. PMID- 29577940 TI - Vascular architecture in free flaps: Analysis of vessel morphology and morphometry in murine free flaps. AB - The aim of this study was to analyze the development of vascular architecture as well as vascular morphometry and morphology of anastomosed microvascular free flaps. Free pectoral skin flaps were raised in 25 rats and anastomosed to the femoral vessels in the groin region. CD31 immunohistology was performed after 3, 7 and 12 d (each 5 animals each) to analyze microvessel density (MVD), microvessel area (MVA) and microvessel size (MVS). Microvascular corrosion casting was performed after 7 and 12 d (5 animals each) to analyze vessel diameter (VD), intervascular distance (IVD), interbranching distance (IBD), and branching angle (BA). Further on, sprout and pillar density as hallmarks of sprouting and intussusceptive angiogenesis were analyzed. Pectoral skin isles from the contralateral side served as controls. A significantly increased MVD was found after 7 and 12 d (p each <0.001). MVA was significantly increased after 3, 7 and 12 d (p each <0.001) and a significantly increased MVS was analyzed after 3 and 7 d (p each <0.001). VD and IVD were significantly increased after 7 and 12 d (p each <0.001). For IBD, a significantly increase was measured after 7 d (p < 0.001). For IBA, sprout and pillar density, no significant differences were found (p each >=0.05). Significant changes in the vascular architecture of free flaps after successful microvascular anastomosis were seen. Since there was no evidence for sprout and pillar formation within the free flaps, the increased MVD and flap revascularization might be induced by the receiving site. PMID- 29577941 TI - How and why do gastrointestinal peptides influence food intake? AB - Despite the ability of some gastrointestinal hormones to reliably reduce meal size when administered prior to a meal, it is not understood why the repeated administration or genetic knockout of these hormones appear largely ineffective in reducing food intake and body weight. Here, we review evidence that the ability of GI peptides such as cholecystokinin (CCK) to elicit satiation is a consequence of prior learning. Evidence includes first, that the ability of some of these signals to modify food intake depends upon past experience and is malleable with new experience. Additionally, the ability of CCK and other gut signals to reduce food intake may not be hard-wired; i.e., any so-called "satiation" signal that reduces food intake in a single-meal situation may not continue to do so over repeated trials. The individual will respond to the signal only so long as it provides reliable information about caloric content. If a particular signal becomes unreliable, the individual will rely on other signals to end meals. Thus, gut peptides/hormones have important metabolic effects such as mediating absorption, digestion, and many aspects of the distribution of ingested nutrients throughout the body; and, if they have been reliably associated with natural stimuli that mediate satiation, they also inform behavior. PMID- 29577942 TI - Emodin protects hyperglycemia-induced injury in PC-12 cells by up-regulation of miR-9. AB - BACKGROUND: Diabetic foot is a severe complication of diabetes mellitus, mainly caused by diabetic peripheral neuropathy. The objective of this study was to investigate the function of emodin (a neuroprotective agent reported previously) in diabetic peripheral neuropathy. METHODS: A neuron-like cell line PC-12 was subjected with high level glucose, before which emodin was applied to treat cells. The expression of miR-9 in cell was overexpressed or suppressed by miRNA transfection. Thereafter, cell viability, apoptosis and autophagy were assessed, respectively. RESULTS: High glucose exhibited cytotoxicity in PC-12 cells. Emodin protected PC-12 cells against high glucose-induced apoptosis and viability impairment. These observations were coupled with the down-regulations of p21, p16, Bax, cleaved caspase-3 and -9, and the up-regulations of CyclinD1 and Bcl-2. Additionally, high glucose-induced autophagy was alleviated by emodin, as Beclin 1 was down-regulated, p62 was up-regulated, and the conversion of LC3-I to LC3-II was decreased. miR-9 was highly expressed in response to emodin treatment. More interestingly, the protective actions of emodin on high glucose-induced injury were reversed by miR-9 suppression. Also, the activation of PI3K/AKT signaling and deactivation of NF-kappaB signaling induced by emodin were recovered by miR-9 suppression. CONCLUSION: Emodin protected PC-12 cells against high glucose induced apoptosis and autophagy. The neuroprotective activities might be realized by up-regulation of miR-9, and modulation of PI3K/AKT and NF-kappaB signaling pathways. PMID- 29577943 TI - Evidence-based adverse outcome pathway approach for the identification of BPA as en endocrine disruptor in relation to its effect on the estrous cycle. AB - Proper cyclicity is essential to reach successful optimal fertility. In rats and mice, BPA exposure is repeatedly and reliably reported to show an adverse effect on the estrous cycle after exposures at different life stages. In humans, a possible association between modifications of menstrual cycle characteristics (e.g. length of the cycle, duration of menstrual bleeding) and sub-fecundity or spontaneous abortion has been observed. Alterations of ovarian cyclicity can therefore be definitely considered as an adverse health outcome. As a prerequisite for the EU REACH regulation to identify a substance as an endocrine disruptor and a SVHC,1 the proof has to be established that the substance can have deleterious health effects resulting from an endocrine mode of action. This review provides an overview of the currently available data allowing to conclude that the adverse effects of BPA exposure on ovarian cyclicity is mediated by an endocrine mode of action.

AB - Upregulation of selenium binding protein 1 (SELENBP1) mRNA expression has been reported in schizophrenia, primarily in the dorsolateral prefrontal cortex. However, peripheral blood studies are limited and results are inconsistent. In this study, we examined SELENBP1 mRNA expression in whole blood and protein expression in plasma from patients with recent-onset schizophrenia (n = 30), treatment-resistant schizophrenia (n = 71) and healthy controls (n = 57). We also examined the effects of SELENBP1 genetic variation on gene and protein expression. We found lower SELENBP1 plasma protein levels in patients with recent onset schizophrenia (p = 0.042) but not in treatment-resistant schizophrenia (p = 0.81). Measurement of peripheral mRNA levels showed no difference between treatment-resistant schizophrenia and healthy controls (p = 0.234) but clozapine plasma levels (p = 0.036) and duration of illness (p = 0.028) were positively correlated with mRNA levels. Genetic variation was not associated with mRNA or protein expression. Our data represent the first peripheral proteomic study of SELENBP1 in schizophrenia and suggest that plasma SELENBP1 protein is downregulated in patients with recent-onset schizophrenia.

AB - The present study aimed to analyze the effect of underground operations on the psychophysiological and memory response of soldiers taking into consideration experience, the use of nocturne vision systems and previous combat actions on the psychophysiological response. Seventy participants were recruited and divided in four groups, three experimental groups with different experimental conditions, SNFV (Soldiers No-Fire Night-Vision), SFV (Soldiers Fire Night-Vision), SNFNV (Soldiers No-Fire No Night-Vision), and one control group, CNFV (Control No-Fire Night-Vision). We analyzed modifications in psychophysiological and memory response pre and post an underground operation. The underground operation produced a significant increase (p < 0.05) in blood lactate, blood oxygen saturation, rated perceived exertion, heart rate, cognitive and somatic anxiety and sympathetic modulation in all groups. Groups with higher stress values scored higher incorrect items in the memory post mission questionnaire. The higher psychophysiological activation correlated positively with cognitive impairment and lower memory. We concluded that an underground operation produced an increase in psychophysiological activation and a negative effect on memory, being modulated by previous training and experience. The lack of special equipment as night vision systems in underground operations induced similar stress response than prior combat actions, decreasing conciseness of time.

AB - This study aimed to reveal electrophysiological markers of communicative and cognitive dysfunctions of different severity in children with autism spectrum disorder (ASD). Eyes-opened electroencephalograms (EEGs) of 42 children with ASD, divided into two groups according to the severity of their communicative and cognitive dysfunctions (24 with severe and 18 children with less severe ASD), and 70 age-matched controls aged 4-9 years were examined by means of spectral and group independent component (gIC) analyses. A predominance of theta and beta EEG activity in both groups of children with ASD compared to the activity in the control group was found in the global gIC together with a predominance of beta EEG activity in the right occipital region. The quantity of local gICs with enhanced slow and high-frequency EEG activity (within the frontal, temporal, and parietal cortex areas) in children 4-9 years of age might be considered a marker of cognitive and communicative dysfunction severity.

PMID- 29577948 TI - l-Arginine induces antioxidant response to prevent oxidative stress via stimulation of glutathione synthesis and activation of Nrf2 pathway. AB - Arginine is a conditionally essential amino acid. To elucidate the influence of l arginine on the activation of endogenous antioxidant defence, male Wistar rats were orally administered daily with l-arginine at different levels of 25, 50, 100 mg/100 g body weight. After 7 and 14 days feeding, the antioxidative capacities and glutathione (GSH) contents in the plasma and in the liver were uniformly enhanced with the increasing consumption of l-arginine, whereas the oxidative stress was effectively suppressed by l-arginine treatment. After 14 days feeding, the mRNA levels and protein expressions of Keap1 and Cul3 were gradually reduced by increasing l-arginine intake, resulting that the nuclear factor Nrf2 was activated. Upon activation of Nrf2, the expressions of antioxidant responsive element (ARE)-dependent genes and proteins (GCLC, GCLM, GS, GR, GST, GPx, CAT, SOD, NQO1, HO-1) were up-regulated by l-arginine feeding, indicating an upward trend in antioxidant capacity uniformly with the increasing consumption of l arginine. The present study demonstrates that the supplementation of l-arginine stimulates GSH synthesis and activates Nrf2 pathway, leading to the up-regulation of ARE-driven antioxidant expressions via Nrf2-Keap1 pathway. Results suggest the availability of l-arginine is a critical factor to suppress oxidative stress and induce an endogenous antioxidant response. PMID- 29577949 TI - Quantification of ligand density and stoichiometry on the surface of liposomes using single-molecule fluorescence imaging. AB - Despite the longstanding existence of liposome technology in drug delivery applications, there have been no ligand-directed liposome formulations approved for clinical use to date. This lack of translation is due to several factors, one of which is the absence of molecular tools for the robust quantification of ligand density on the surface of liposomes. We report here for the first time the quantification of proteins attached to the surface of small unilamellar liposomes using single-molecule fluorescence imaging. Liposomes were surface-functionalized with fluorescently labeled human proteins previously validated to target the cancer cell surface biomarkers plasminogen activator inhibitor-2 (PAI-2) and trastuzumab (TZ, Herceptin(r)). These protein-conjugated liposomes were visualized using a custom-built wide-field fluorescence microscope with single molecule sensitivity. By counting the photobleaching steps of the fluorescently labeled proteins, we calculated the number of attached proteins per liposome, which was 11 +/- 4 proteins for single-ligand liposomes. Imaging of dual-ligand liposomes revealed stoichiometries of the two attached proteins in accordance with the molar ratios of protein added during preparation. Preparation of PAI 2/TZ dual-ligand liposomes via two different methods revealed that the post insertion method generated liposomes with a more equal representation of the two differently sized proteins, demonstrating the ability of this preparation method to enable better control of liposome protein densities. We conclude that the single-molecule imaging method presented here is an accurate and reliable quantification tool for determining ligand density and stoichiometry on the surface of liposomes. This method has the potential to allow for comprehensive characterization of novel ligand-directed liposomes that should facilitate the translation of these nanotherapies through to the clinic. PMID- 29577950 TI - Primary deuterium kinetic isotope effects prolong drug release and polymer biodegradation in a drug delivery system. AB - We have developed a chemically-controlled drug delivery system in which a drug is covalently attached via a carbamate to hydrogel microspheres using a beta eliminative linker; rate-determining proton removal from a CH bond adjacent to an electron withdrawing group results in a beta-elimination to cleave the carbamate and release the drug. After subcutaneous injection of the hydrogel-drug conjugate, the drug is slowly released into the systemic circulation and acquires an elimination t1/2,beta that matches the t1/2 of linker cleavage. A similar beta eliminative linker with a slower cleavage rate is installed into crosslinks of the polymer to trigger gel degradation after drug release. We have now prepared beta-eliminative linkers that contain deuterium in place of the hydrogen whose removal initiates cleavage. In vitro model systems of drug release and degelation show large primary deuterium kinetic isotope effects of kH/kD ~ 2.5 to 3.5. Using a deuterated linker to attach the peptide octreotide to hydrogel-microspheres, the in vivo t1/2,beta of the drug was increased from ~1.5 to 4.5 weeks in the rat. Similarly, the in vivo time to biodegradation of hydrogels with deuterium containing crosslinks could be extended ~2.5-fold compared to hydrogen-containing counterparts. Thus, the use of primary deuterium kinetic isotope effects in a single platform technology can control rates of beta-elimination reactions in drug release and polymer biodegradation rates. PMID- 29577951 TI - Interaction of porcine reproductive and respiratory syndrome virus major envelope proteins GP5 and M with the cellular protein Snapin. AB - BACKGROUND: Porcine reproductive and respiratory syndrome (PRRS) is characterized by abortions in pregnant sows and respiratory disease, particularly in young pigs. The causative agent is porcine reproductive and respiratory syndrome virus (PRRSV), a member of the arterivirus family. GP5 and M are the major envelope proteins encoded by PRRSV. To further characterize these two viral proteins, a yeast two-hybrid approach was utilized to identify interacting partners of PRRSV GP5 and M proteins. METHODS: Interacting partners of PRRSV GP5 and M were identified using a porcine macrophage cDNA library yeast two-hybrid screen. Subsequently, the interactions between PRRSV GP5/M and the cellular protein Snapin were mapped using truncated versions of the GP5 and M proteins in a yeast two-hybrid assay to localize the interactions. The Snapin gene from the African green monkey kidney cell line MARC-145, which is permissive to PRRSV, was cloned and sequenced, and compared to porcine Snapin. Cellular Snapin expression was reduced in PRRSV-infected cells via Snapin-specific siRNA targeting. RESULTS: Here we show that the cellular Snap-Associated Protein (Snapin), an accessory protein of the SNARE membrane fusion network and also a member of the BLOC-1 complex, specifically interacts with GP5 and M. Inhibition of Snapin expression via siRNA targeting of Snapin results in the reduction of PRRSV replication. CONCLUSIONS: The PRRSV GP5 and M proteins are known to form a heterodimeric complex which is important for viral structure and infectivity, and both PRRSV proteins can interact with cellular Snapin. Snapin knock-down suggests these interactions could be important in the PRRSV lifecycle. GP5 and M proteins may interact with Snapin to exploit its roles in intracellular transport and membrane fusion. PMID- 29577952 TI - Lipid transfer protein isolated from noni seeds displays antibacterial activity in vitro and improves survival in lethal sepsis induced by CLP in mice. AB - In the present study, we aimed to evaluate the antibacterial activity of a lipid transfer protein isolated from Morinda citrifolia L. seeds, named McLTP1, and to investigate its effect in the cecal ligation and puncture (CLP) mouse sepsis model. Antimicrobial assays revealed that McLTP1 (12.5-800 MUg/mL) significantly reduced Staphylococcus aureus (ATCC 6538P and ATCC 14458) and Staphylococcus epidermidis (ATCC 12228) planktonic growth, reaching maximal inhibition of approximately 50% and 98%, respectively. Furthermore, McLTP1 inhibited biofilm formation of both S. aureus strains, achieving percentages ranging from 39.1% to 69.1% (200-800 MUg/mL) for ATCC 6538P and 34.4%-63% (12.5-800 MUg/mL) for ATCC 14458. A synergistic interaction between McLTP1 and oxacillin against S. aureus and S. epidermidis was also observed, as determined by fractional inhibitory concentration indices of 0.18 and 0.38, respectively. McLTP1 showed no significant inhibitory effect against Gram-negative bacteria. In the in vivo experiments, sepsis was lethal to 83% of the animals, 72 h after CLP. In contrast, 100% of the animals treated with McLTP1 (8 mg/kg) before (intraperitoneal injection or oral dose) or after (oral dose) CLP were still alive 3 days later. In addition, oral or intraperitoneal administration of McLTP1 (8 mg/kg) significantly reduced the body weight loss, fever, leukocytosis, organ damage, and the level of inflammatory serum cytokines induced by sepsis. In conclusion, McLTP1 could be exploited for its antimicrobial properties, and can be considered a potential therapeutic candidate for the management of clinical sepsis.

AB - The regioselective Cu(I)-catalyzed 1,3-dipolar cycloaddition of 17alpha- and 17beta-azidoandrost-5-en-3beta-ol epimers (3b and 5b) with different terminal alkynes afforded novel 1,4-substituted triazolyl derivatives (8a-k and 9a-k). For the preparation of 5'-iodo-1',2',3'-triazoles (8m-n and 9m-n), an improved method was developed, directly from steroidal azides and terminal alkynes, in reaction mediated by CuI and ICl as iodinating agents. Acetolysis and subsequent hydrolysis of 8n and 9n yielded 5'-hydroxy-1',2',3'-triazoles 8o and 9o. The inhibitory effect of 8a-o, 9a-o, 3, and 5 on rat testicular C17,20-lyase was investigated by means of an in vitro radioincubation technique. The results revealed that the C-17 epimers of steroidal triazoles influence the C17,20-lyase effect. Inhibitors were found only in the 17alpha-triazolyl series (8a-o), whereas in the C-17 azide pair the 17beta compound (5b) was more potent. PMID- 29577954 TI - Assessment of flow dynamics in retinal and choroidal microcirculation. AB - Alterations in ocular blood flow have been implicated in mechanisms that lead to vision loss in patients with various ocular disorders such as diabetic retinopathy, glaucoma, and age-related macular degeneration. Assessment of retinal and choroidal blood flow is also a window to evaluate systemic diseases that affect microvasculature. Quantification and qualification of the blood flow in the retina and choroid help us understand pathophysiology, stratify disease risk, and monitor disease progression in these disorders. Multiple methods are used by researchers for assessment of blood flow, but a gold standard is lacking. We review commonly used methods, both invasive and noninvasive, for evaluation of blood flow, including intravital microscopy, laser Doppler velocimetry, laser Doppler flowmetry, laser interferometry, confocal scanning laser Doppler flowmetry, laser speckle flowgraphy, Doppler optical coherence tomography, blue field entoptic simulation, retinal vessel caliber assessment, optical coherence tomography angiography, retinal function imaging, color Doppler imaging, and scanning laser ophthalmoscope angiogram. As technology evolves, better evaluation of blood flow in various ocular and systemic diseases will likely bring new perspectives into clinical practice and translate to better diagnosis and treatment. PMID- 29577955 TI - Adrenomedullin: Continuing to explore cardioprotection. AB - Adrenomedullin (AM), a peptide isolated from an extract of human pheochromocytoma, comprises 52 amino acids with an intramolecular disulfide bond and amidation at the carboxy-terminus. AM is present in various tissues and organs in rodents and humans, including the heart. The peptide concentration increases with cardiac hypertrophy, acute myocardial infarction, and overt heart failure in the plasma and the myocardium. The principal function of AM in the cardiovascular system is the regulation of the vascular tone by vasodilation and natriuresis via cyclic adenosine monophosphate-dependent or -independent mechanism. In addition, AM may possess unique properties that inhibit aldosterone secretion, oxidative stress, apoptosis, and stimulation of angiogenesis, resulting in the protection of the structure and function of the heart. The AM receptor comprises a complex between calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein (RAMP) 2 or 3, and the AM-CLR/RAMP2 system is essential for heart development during embryogenesis. Small-scale clinical trials have proven the efficacy and safety of recombinant AM peptide therapy for heart failure. Gene delivery and a modified AM peptide that prolongs the half-life of the native peptide could be an innovative method to improve the efficacy and benefit of AM in clinical settings. In this review, we focus on the pathophysiological roles of AM and its receptor system in the heart and describe the advances in AM and proAM-derived peptides as diagnostic biomarkers as well as the therapeutic application of AM and modified AM for cardioprotection. PMID- 29577956 TI - Toll immune signal activates cellular immune response via eicosanoids. AB - Upon immune challenge, insects recognize nonself. The recognition signal will propagate to nearby immune effectors. It is well-known that Toll signal pathway induces antimicrobial peptide (AMP) gene expression. Eicosanoids play crucial roles in mediating the recognition signal to immune effectors by enhancing humoral immune response through activation of AMP synthesis as well as cellular immune responses, suggesting a functional cross-talk between Toll and eicosanoid signals. This study tested a cross-talk between these two signals. Two signal transducing factors (MyD88 and Pelle) of Toll immune pathway were identified in Spodoptera exigua. RNA interference (RNAi) of either SeMyD88 or SePelle expression interfered with the expression of AMP genes under Toll signal pathway. Bacterial challenge induced PLA2 enzyme activity. However, RNAi of these two immune factors significantly suppressed the induction of PLA2 enzyme activity. Furthermore, RNAi treatment prevented gene expression of cellular PLA2. Inhibition of PLA2 activity reduced phenoloxidase activity and subsequent suppression in cellular immune response measured by hemocyte nodule formation. However, immunosuppression induced by RNAi of Toll signal molecules was significantly reversed by addition of arachidonic acid (AA), a catalytic product of PLA2. The addition also significantly reduced the enhanced fungal susceptibility of S. exigua treated by RNAi against two Toll signal molecules. These results indicate that there is a cross-talk between Toll and eicosanoid signals in insect immunity. PMID- 29577957 TI - Aluminum is a powerful adjuvant in teleost fish despite failing to induce interleukin-1beta release. AB - Although aluminum salts (Alum) have been extensively used in human vaccination for decades, its mechanism of action is controversial. In fish, the use of Alum as a vaccine adjuvant is scarce and there are no studies aimed at identifying its mechanism of action. In the present study we report that Alum is a powerful adjuvant in the gilthead seabream (Sparus aurata L., Sparidae) and the European seabass (Dicentrarchus labrax L. Moronidae). Thus, Alum increased the specific antibody titers to the model antigen keyhole limpet hemocyanin as the commonly used Freund's adjuvant did in both species. In addition, both adjuvants were able to increase the transcript levels of the gene encoding the major pro-inflammatory mediator interleukin-1beta (Il1b). Strikingly, however, Alum failed to promote Il1b release by seabream leukocytes and even impaired Il1b induction, processing and release in macrophages. However, it increased NADPH oxidase-dependent reactive oxygen species (ROS) production in gilthead seabream leukocytes and purified granulocytes. In addition, Alum promoted gilthead seabream leukocyte death independently of ROS production and caspases, suggesting that damage associated molecular patterns release from dying cells mediate Alum adjuvant activity. Our results pave the way for future studies aimed at investigating the relevance of danger signals generated by Alum in vivo on its adjuvant activity in order to increase our understanding of the mechanisms of action of Alum in fish vaccines and to help in the design of new adjuvants for aquaculture. PMID- 29577958 TI - The validation & verification of an LC/MS method for the determination of total docosahexaenoic acid concentrations in canine blood serum. AB - Docosahexaenoic acid (DHA), is an omega 3 fatty acid (n-3 FA) that has been shown to play a role in canine growth and physiological integrity and improvements in skin and coat condition. However, potential adverse effects of n-3 FA specifically, impaired cellular immunity has been observed in dogs fed diets with elevated levels of n-3 FA. As such, a safe upper limit (SUL) for total n-3 FAs (DHA and EPA) in dogs has been established. Considering this SUL, sensitive methods detecting DHA in blood serum as a biomarker when conducting n-3 FA supplementation trials involving dogs are required. In this study, an LC-ESI MS/MS method of DHA detection in dog serum was validated and verified. Recovery of DHA was optimized and parallelism tests were conducted with spiked samples demonstrating that the serum matrix did not interfere with quantitation. The stability of DHA in serum was also investigated, with -80 degrees C considered suitable when storing samples for up to six months. The method was linear over a calibration range of 1-500 MUg/mL and precision and accuracy were found to meet the requirements for validation. This method was verified in an alternative laboratory using a different analytical system and operator, with the results meeting the criteria for verification. PMID- 29577959 TI - Sirtuin activators and inhibitors: Promises, achievements, and challenges. AB - The NAD+-dependent protein lysine deacylases of the Sirtuin family regulate various physiological functions, from energy metabolism to stress responses. The human Sirtuin isoforms, SIRT1-7, are considered attractive therapeutic targets for aging-related diseases, such as type 2 diabetes, inflammatory diseases and neurodegenerative disorders. We review the status of Sirtuin-targeted drug discovery and development. Potent and selective pharmacological Sirt1 activators and inhibitors are available, and initial clinical trials have been carried out. Several promising inhibitors and activators have also been described for other isoforms. Progress in understanding the mechanisms of Sirtuin modulation by such compounds provides a rational basis for further drug development. PMID- 29577960 TI - Functional dissociation of temporal processing mechanisms during speech production and hand movement: An ERP study. AB - Skilled motor actions are mediated by neural mechanisms that incorporate sensory feedback for driving or suppressing movement with remarkable temporal precision. The predictive coding model proposes that the brain performs this function by establishing an internal representation of timing to accelerate movement response time. However, it is unclear whether different neural mechanisms are involved in temporal processing of movement initiation and cessation. The present study examined how temporal information is encoded for initiation and cessation of speech and hand movement. Event-related potentials (ERPs) were recorded while young healthy subjects performed speech and hand movement initiation and cessation in response to temporally predictable and unpredictable visual stimuli. We found that predictable stimuli elicited faster movement in both speech and hand modalities, with shorter reaction times associated with movement cessation compared with initiation. Analysis of ERPs revealed that premotor neural activities were significantly attenuated before speech initiation and hand movement initiation and cessation for temporally predictable vs. unpredictable conditions, but an opposite pattern was observed for speech cessation. In addition, we observed that the premotor ERPs were significantly modulated during speech initiation vs. cessation, but no such effect was found during hand movement. Finally, we found that the premotor ERPs were strongly correlated with motor reaction time during movement initiation and cessation for speech and hand modalities only in response to temporally predictable stimuli. These findings indicate that premotor ERPs reflect a temporal predictive code for planning of movement initiation and cessation and highlight functional dissociation of temporal processing mechanisms in speech and hand motor systems. PMID- 29577961 TI - Sleep-related brain atrophy and disrupted functional connectivity in older adults. AB - Aging associates with sleep dysfunction as well as brain alterations. However, the association between age-related brain alterations and their subjective sleep changes is less understood. To address this issue, we recorded T1 weighted structural and resting-state functional magnetic resonance imaging from both young (n = 62) and older adults (n = 108). In addition, all participants completed a battery of psychometric tests, including the Pittsburg Sleep Quality Index. We found that the age-related atrophy of cerebral gray matter, hippocampal and thalamic volume were associated with subjective sleep decline, and the atrophy of cerebral gray matter mediated the age effect on sleep. In addition, older adults exhibited decreased functional connectivity within the medial temporal lobe subsystem than their young counterparts. Moreover, there is a significant positive association between sleep and functional connectivity in young but not in older adults. In light of our findings, we suggest a neuropathological model in which age-related brain alterations may partially explain the well-documented declines in sleep with aging. PMID- 29577962 TI - Correlations between donor-specific antibodies and non-adherence with chronic active antibody-mediated rejection phenotypes and their impact on kidney graft survival. AB - Chronic-active antibody-mediated rejection (CAABMR) is associated with poor kidney graft survival and has no clear effective treatment. Forty-one cases of CAABMR were detected in indication graft biopsies and evaluated according to current Banff classification. We investigated the impact of concurrent donor specific antibodies (DSA) and their characteristics, together with non-adherence regarding immunosuppression on CAABMR histopathological phenotypes and prognosis. Twenty-four (59%) patients had detectable DSA at biopsy, with 15 of them being considered non-adherent. Graft function at biopsy was similar in DSA (+) and (-) patients. DSA (+) patients had significantly higher tubulointerstitial inflammation (i and ti) and acute humoral (g+ptc+v+C4d) composite score than DSA (-). DSA (+)/non-adherent cases presented additionally with increased microvascular inflammation (ptc and v), besides having a distinctively lower ah score. C1q DSA strength was higher (P = .046) in non-adherent patients and correlated closely with C4d score (P = .002). Lower graft function and ah score, higher proteinuria and ci + ct score, and, separately per each model, DSA (+) (HR = 2.446, P = .034), DSA (+)/non-adherent (HR = 3.657, P = .005) and DSA (+)/C1q (+) (HR = 4.831, P = .003) status were independent predictors of graft failure. CAABMR with concomitant DSA pose a higher risk of graft failure. Adherence should be evaluated, and histopathological phenotyping and DSA characterization may add critical information. PMID- 29577963 TI - Dopamine D1 and D3 receptor polypharmacology as a potential treatment approach for substance use disorder. AB - In the search for efficacious pharmacotherapies to treat cocaine addiction much attention has been given to agents targeting dopamine D1 or D3 receptors because of the involvement of these receptors in drug-related behaviors. D1-like and D3 receptor partial agonists and antagonists have been shown to reduce drug reward, reinstatement of drug seeking and conditioned place preference in rodents and non human primates. However, translation of these encouraging results to clinical settings has been limited due to a number of factors including toxicity, poor pharmacokinetic properties and extrapyramidal and sedative side effects. This review highlights the role of D1 and D3 receptors in drug reward and seeking, the discovery of D1-D3 heteromers and their potential as targets in the treatment of addiction. PMID- 29577964 TI - Resuscitation registers: How many active registers are there and how many collect data on paediatric cardiac arrests? AB - BACKGROUND: Cardiac arrest, particularly in children, often has a poor outcome and international guidelines highlight significant gaps in the evidence base for effective resuscitation. Whilst randomised controlled trials for some interventions can be justified, they are not appropriate for many aspects of resuscitation. Therefore, guidelines must use other sources of data such as epidemiological evidence from cardiac arrest registries, to improve the efficacy of resuscitation. The aim of our study was to identify existing national cardiac arrest registries and document key information about the registries, including whether they contain data on paediatric arrests. METHODS: Key bibliographic databases were searched for papers about or using data from cardiac arrest registries. Two reviewers independently screened the search results for relevant papers. A list of registers named in the papers was compiled and information obtained from the papers and the websites of registers where possible. RESULTS: Twenty three active national or large regional cardiac arrest registries were identified. These included five international collaborations and 10 registries that cover a population of at least 10 million people. Twelve registries are based in Europe, five in North America, four in Asia and two in Australasia. The registries vary in their organisation, but the majority (20) defer to the Utstein reporting guidelines for cardiac arrest. Registries covered populations between 0.4 and 174.5 million and contained between 100 and 605,505 records. Sixteen collected data on out-of-hospital arrests only; three in-hospital arrests only; and four included both. For ten registers the number of paediatric arrests was available and ranged from 56 to 3900. CONCLUSIONS: To our knowledge this report contains the most complete list of active national and large regional cardiac arrest registries. Register data support current guidelines on effective resuscitation however, even the largest registries include relatively small numbers, particularly of paediatric events. A less fragmented approach has the potential to improve the utility of registration data for the benefit of patients. PMID- 29577965 TI - Bisphenol A-Induced changes in the enteric nervous system of the porcine duodenum. AB - Bisphenol A (BPA) is an organic compound from the phenolic group commonly used for the production of plastics. The use of BPA in food and drinking water containers carries a significant risk to human health since BPA can be washed out and enter consumables. BPA entering the human body with food shows a multi directional effect and causes disorders in the functioning of many systems and organs. There is no current knowledge about the effects of BPA on the enteric nervous system. The purpose of the present study was to verify the influence of BPA on tolerable daily intake (TDI) dose (0.05 mg/kg body weight/day) and a dose ten times higher than TDI (0.5 mg/kg body weight/day) administered for 28 days on the porcine duodenum. The neurochemical characterization of the enteric neurons to five active neuronal substances was then investigated: substance P (SP), vasoactive intestinal polypeptide (VIP), galanin (GAL), vesicular acetylcholine transporter (VAChT) or cocaine- and amphetamine-regulated transcript peptide (CART) with double immunofluorescence method. Both doses of BPA caused visible changes in duodenal immunoreactivity to the majority of neuronal factors studied and the obtained results show that even TDI dose may affect the living organism. PMID- 29577966 TI - Intracellular Delivery of HCV NS3p gene using vectored particles. AB - Viral hepatitis caused by the hepatitis C virus (HCV) affects millions of people worldwide. The non-structural protein 3 (NS3), one of the most conserved proteins in HCV, is the target of many therapeutic studies. The NS3 protease domain (NS3p) has a range of cytotoxic T lymphocyte (CTL) epitopes, and synthesizing the protein inside the cells is the most appropriate way to present it to the immune system. We developed a tool to study this kind of presentation, using two vectored particle (VP) systems, one based on the Semliki Forest virus (SFV) and the other on HCV pseudoparticles (HCVpp), both carrying the protease domain of the NS3 gene. In addition to producing the particles, we developed a method to quantify these VPs using qRT-PCR. We produced batches of approximately 2.4 * 104 SFV-NS3p/MUL and 4.0 * 102 HCVpp-NS3p/MUL. BHK-21 and HuH-7 cells treated with the VPs expressed the NS3 protein, thus showing the functionality of this system. PMID- 29577967 TI - Comparative analysis of two methods to detect donor-specific anti-HLA antibodies after kidney transplant. AB - Preformed anti-human leukocyte antigen (HLA) antibodies may be present in the blood of kidney transplant candidates. The production of these antibodies may occur in the post-transplant period, with the possible development of donor specific antibodies (DSA). Luminex-based tests, such as the single antigen (SA) assay and the Luminex crossmatch (Xm-DSA) assay are the most commonly used tools to detect anti-HLA antibodies, due to their high sensitivity and specificity. This cross-sectional study aimed to compare the findings of two methods for the detection of DSAs after kidney transplant: SA and Xm-DSA. A total of 122 patients who underwent deceased donor kidney transplant at Hospital de Clinicas de Porto Alegre were included. The SA assay detected anti-class I HLA DSAs in 17 patients (13.9%) and anti-class II HLA DSAs in 22 patients (19.6%), whereas the Xm-DSA detected DSAs in 18 patients (14.8%) both against class I and class II antigens. There was agreement between the two methods for class I (kappa = 0.66, p = 0.001) and class II (kappa = 0.54, p = 0.025) antigens. The incidence of DSAs as obtained by the SA assay was 15.57%, and the most prevalent DSAs were those against HLA-DR antigens. Patient survival at 3 years was 92%. The two techniques assessed in this study provide important information on the presence of DSAs and may help in the post-transplant patient monitoring and in immunosuppressive strategy. PMID- 29577968 TI - Glucocorticoids impair platelet thromboxane biosynthesis in community-acquired pneumonia. AB - Previous reports suggest that community-acquired pneumonia (CAP) is associated with an enhanced risk of myocardial infarction (MI) and that enhanced platelet activation may play a role. Aims of this study were to investigate if urinary excretion of 11-dehydro-thromboxane (Tx) B2, a reliable marker of platelet activation in vivo, was elevated in CAP and whether glucocorticoid administration reduced platelet activation. Three-hundred patients hospitalized for CAP were recruited and followed-up until discharge. Within the first 2 days from admission, urinary 11-dehydro-TxB2 and serum levels of methylprednisolone and betamethasone were measured. 11-Dehydro-TxB2 was also measured in a control group of 150 outpatients, matched for age, sex, and comorbidities. Finally, in-vitro studies were performed to assess if glucocorticoids affected platelet activation, at the same range of concentration found in the peripheral circulation of CAP patients treated with glucocorticoids. Compared to controls, CAP patients showed significantly higher levels of 11-dehydro-TxB2 (110 [69-151] vs. 163 [130-225] pg/mg creatinine; p < 0.001). During the in-hospital stay, 31 patients experienced MI (10%). A COX regression analysis showed that 11-dehydro-TxB2 independently predicted MI (p = .005). CAP patients treated with glucocorticoids showed significantly lower levels of 11-dehydro-TxB2 compared to untreated ones (147 [120-201] vs. 176 [143-250] pg/mg creatinine; p < 0.001). In vitro, glucocorticoids-treated platelets showed a dose-dependent decrease of ADP-induced platelet aggregation, TxB2 production, cPLA2 phosphorylation and arachidonic acid release from the platelet membrane. In conclusion, platelet TxB2 is overproduced in CAP patients and may be implicated in MI occurrence. Glucocorticoids reduce platelet release of TxB2 in vitro and urinary excretion of 11-dehydro-TxB2 in vivo and may be a novel tool to decrease platelet activation in this setting.

AB - Chagas disease, caused by Trypanosoma cruzi, is an important global public health problem which, despite partial efficacy of benznidazole (Bz) in acute phase, urgently needs an effective treatment. Cardiotoxicity is a major safety concern for conduction of more accurate preclinical drug screening platforms. Human induced pluripotent stem cells derived cardiomyocytes (hiPSC-CM) are a reliable model to study genetic and infectious cardiac alterations and may improve drug development. Herein, we introduce hiPSC-CM as a suitable model to study T. cruzi heart infection and to predict the safety and efficacy of anti-T. cruzi drugs. PMID- 29577970 TI - Can hi-jacking hypoxia inhibit extracellular vesicles in cancer? AB - Increasing evidence indicates that extracellular vesicles (EVs) are key players in undesirable cell-cell communication in cancer. However, the release of EVs is not unique to cancer cells; normal cells release EVs to perform physiological roles. Thus, selective inhibition of EV release from cancer cells is desirable. Hypoxia contributes to tumour development and aggressiveness. EV quantities and thus undesirable communications are substantially increased in hypoxia. Targeting hypoxia could selectively inhibit EV release from tumour cells without disturbing physiologically relevant EVs. The unfavourable association between hypoxia and EV release is evident in multiple tumour types; therefore, targeting hypoxia could have a broad therapeutic benefit.

PMID- 29577973 TI - The effect of n-3 fatty acids and coenzyme Q10 supplementation on neutrophil leukotrienes, mediators of inflammation resolution and myeloperoxidase in chronic kidney disease. AB - BACKGROUND: Neutrophils release leukotriene (LT)B4 and myeloperoxidase (MPO) that may be important mediators of chronic inflammation in chronic kidney disease (CKD). The n-3 fatty acids (n-3 FA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have the potential to attenuate inflammation through production of LTB5 and the Specialized Proresolving Lipid Mediators (SPM) that promote the resolution of inflammation. In animal models, coenzyme Q10 (CoQ) also attenuates inflammation by reducing MPO and LTB4. OBJECTIVE: This study evaluated the independent and combined effects of n-3 FA and CoQ supplementation on neutrophil leukotrienes, the pro-inflammatory eicosanoid 5 hydroxyeicosatetraenoic acid (5-HETE), SPM, and plasma MPO, in patients with CKD. DESIGN: In a double-blind, placebo-controlled intervention of factorial design, 85 patients with CKD were randomized to either n-3 FA (4 g), CoQ (200 mg), both supplements, or control (4 g olive oil), daily for 8 weeks. Plasma MPO and calcium ionophore-stimulated neutrophil release of LTs, 5-HETE and SPM were measured at baseline and after 8 weeks. RESULTS: Seventy four patients completed the intervention. n-3 FA, but not CoQ, significantly increased neutrophil LTB5 (P < 0.0001) and the SPM 18-hydroxyeicosapentaenoic acid (18-HEPE), resolvin E1 (RvE1), resolvin E2 (RvE2) and resolvin E3 (RvE3) that derive from EPA, as well as 17-hydroxydocosahexaenoic acid (17-HDHA) and resolvin D5 (RvD5) that derive from DHA (all P < 0.01). Neutrophil LTB4 and its metabolites, and 5-HETE were not significantly altered by n-3 FA or CoQ. Plasma MPO was significantly reduced with n-3 FA alone (P = 0.013) but not when given in combination with CoQ. CONCLUSION: n-3 FA supplementation in patients with CKD leads to increased neutrophil release of LTB5 and several SPM, as well as a reduction in plasma MPO that may have important implications for limiting chronic inflammation.

AB - This randomized clinical trial compared the neuromuscular adaptations induced by concurrent training (CT) performed with repetitions to concentric failure and not to failure in elderly men. Fifty-two individuals (66.2 +/- 5.2 years) completed the pre- and post-measurements and were divided into three groups: repetitions to failure (RFG, n = 17); repetitions not to failure (NFG, n = 20); and repetitions not to failure with total volume equalized to RFG (ENFG, n = 15). Participants were assessed in isometric knee extension peak torque (PTiso), maximal strength (1RM) in the leg press (LP) and knee extension (KE) exercises, quadriceps femoris muscle thickness (QF MT), specific tension, rate of torque development (RTD) at 50, 100 and 250 ms, countermovement jump (CMJ) and squat jump (SJ) performance, as well as maximal neuromuscular activity (EMGmax) of the vastus lateralis (VL) and rectus femoris (RF) muscles. CT was performed over 12 weeks, twice weekly. Along with each specific strength training program, each group also underwent an endurance training in the same session. After training, all groups improved similarly and significantly in LP and KE 1RM, PTiso, CMJ and SJ performance, RTD variables, specific tension, and VL EMGmax, (P < 0.05-0.001). QF MT improved only in RFG and ENFG (P < 0.01). These results suggest that repetitions until concentric failure does not provide further neuromuscular performance gains and muscle hypertrophy, and that even a low number of repetitions relative to the maximal possible (i.e., 50%) optimizes neuromuscular performance in elderly men. Moreover, training volume appears to be more important for muscle hypertrophy than training using maximal repetitions.

AB - The use of iron oxide nanoparticles for different biomedical applications, hold immense promise to develop negative tissue contrast in magnetic resonance imaging (MRI). Previously, we have optimized the labelling of mesenchymal stem cells (MSCs) with iron oxide nanoparticles complexed to different transfection agents like poly-l-lysine (IO-PLL) and protamine sulfate (Fe-Pro) on the basis of relaxation behaviour and its biological expressions. However, there is a distinct need to investigate the biocompatibility and biosafety concerns coupled with its cytotoxicity and genotoxicity. This study was prepared to evaluate the viability of cells, generation of ROS, changes in actin cytoskeleton, investigation of cell death, level of GSH and TAC, activities of SOD and GPx, and stability of DNA in MSCs after labelling. Results demonstrated a marginal alteration in toxicological parameters like ROS generation, cell length, actin cytoskeleton, total apoptosis and DNA damage was detected after stem cell labelling. Insignificant depletion of GSH and SOD level, and increase in GPx and TAC level in MSCs were measured after labelling with IO-PLL and Fe-Pro complexes, which later on recovered and normalized to its baseline. This MSCs labelling could provide a reference guideline for toxicological analysis and relaxometry based in vivo MRI detection.

AB - Cytoplasmic Male Sterility is maternally inherited trait in plants, characterized by failure to produce functional pollen during anther development. Anther development is modulated through the interaction of nuclear and mitochondrial genes. In the present study, differential gene expression of floral buds at the sporogenous stage (SS) and microsporocyte stage (MS) between CGMS and its fertile maintainer line of cotton plants was studied. A total of 320 significantly differentially expressed genes, including 20 down-regulated and 37 up-regulated in CGMS comparing with its maintainer line at the SS stage, as well as and 89 down-regulated and 4 up-regulated in CGMS compared to the fertile line at MS stage. Comparing the two stages in the same line, there were 6 down-regulated differentially expressed genes only induced in CGMS and 9 up-regulated differentially expressed gene only induced in its maintainer. GO analysis revealed essential genes responsible for pollen development, and cytoskeleton category show differential expression between the fertile and CGMS lines. Validation studies by qRT-PCR shows concordance with RNA-seq result. A set of novel SSRs identified in this study can be used in evaluating genetic relationships among cultivars, QTL mapping, and marker-assisted breeding. We reported aberrant expression of genes related to pollen exine formation, and synthesis of pectin lyase, myosine heavy chain, tubulin, actin-beta, heat shock protein and myeloblastosis (MYB) protein as targets for CMS in cotton. The results of this study contribute to basic information for future screening of genes and identification of molecular portraits responsible for CMS as well as to elucidate molecular mechanisms that lead to CMS in cotton.

AB - Keratinocyte proliferation and migration is essential during re-epithelialisation for the restoration of the epithelial barrier during skin wound healing. Numerous growth factors are involved in the stimulation of keratinocyte proliferation and migration. The signalling pathways that drive these processes during wound healing are not well defined. This study investigated thrombin-mediated signalling in keratinocytes. The thrombin receptor, protease-activated receptor 1 (PAR-1) is a seven transmembrane G-protein coupled receptor that is known to transactivate the epidermal growth factor receptor (EGFR). Immortalized human keratinocytes (HaCaT cells) were treated with thrombin and selective inhibitors to EGFR and MAP kinases. Whole cell lysates were separated on SDS-PAGE and analysed by Western blot using antibodies against transcription factor Smad2. Quantitative real-time polymerase chain reaction was used to measure the mRNA expression of PAI-1 while scratch wound assays were used to measure keratinocyte migration. Western blot data showed that thrombin mediates PAR-1 transactivation of EGFR and the downstream phosphorylation of the transcription factor Smad2 linker (Smad2L) region. ERK1/2 inhibition by UO126 caused a decrease in Smad2L phosphorylation while the p38 inhibitor SB202190 and JNK inhibitor SP600125 did not. Smad2L Ser250 was specifically phosphorylated by this thrombin mediated pathway while Ser245 and Ser255 were not. Thrombin increased PAI-1 mRNA expression and keratinocyte migration and this was reduced when either EGFR or ERK1/2 were blocked. Taken together these results show that thrombin mediated mRNA expression of PAI-1 in keratinocytes and migration occurs via EGFR transactivation and involves signalling intermediates ERK1/2 and Smad2 and may be a key pathway in skin wound healing.

PMID- 29577982 TI - Human single-stranded DNA binding protein 1 (hSSB1, OBFC2B), a critical component of the DNA damage response. AB - Our genomic DNA is found predominantly in a double-stranded helical conformation. However, there are a number of cellular transactions and DNA damage events that result in the exposure of single stranded regions of DNA. DNA transactions require these regions of single stranded DNA, but they are only transient in nature as they are particularly susceptible to further damage through chemical and enzymatic degradation, metabolic activation, and formation of secondary structures. To protect these exposed regions of single stranded DNA, all living organisms have members of the Single Stranded DNA Binding (SSB) protein family, which are characterised by a conserved oligonucleotide/oligosaccharide-binding (OB) domain. In humans, three such proteins members have been identified; namely the Replication Protein A (RPA) complex, hSSB1 and hSSB2. While RPA is extremely well characterised, the roles of hSSB1 and hSSB2 have only emerged recently. In this review, we discuss the critical roles that hSSB1 plays in the maintenance of genomic stability. PMID- 29577981 TI - Perfluorooctane sulfonate mediates secretion of IL-1beta through PI3K/AKT NF-kB pathway in astrocytes. AB - Perfluorooctane sulfonate (PFOS) is a persistent and bioaccumulative compound that has been widely used in various fields of life and industrial productions, because of its special chemical and physical properties. Numerous studies have indicated significant neurotoxic effect of PFOS, especially on neurons and microglia. However, the influence of PFOS on astrocyte physiology remains unclear. In this study, we showed that PFOS triggered reactive astrocytosis in time- and dose-dependent manners. The low-doses of PFOS increased the cell number and the expression of glial fibrillary acidic protein (GFAP), a well-known hallmark of reactive astrocytes, in C6 astrocyte cells. ELISA and RT-PCR analysis showed that PFOS promoted the expression and secretion of Interleukin-1 beta (IL 1beta) in dose- and time-dependent manners. Furthermore, PFOS exposure could induce the phosphorylation and degradation of IkappaBalpha, and the translocation of NF-kappaB p65 from the cytoplasm to the nucleus in C6 glioma cell line. Thus, the NF-kB signaling pathway can be activated after PFOS exposure. In addition, pretreatment with AKT inhibitor LY294002 could obviously attenuate PFOS-induced NF-kappaB activation and IL-1beta secretion. Taken together, these results indicated that PFOS could facilitate reactive astrocytosis and the secretion of pro-inflammatory cytokines through AKT-dependent NF-kappaB signaling pathway. PMID- 29577983 TI - Age-related NMDA signaling alterations in SOD2 deficient mice. AB - Oxidative stress affects the survival and function of neurons. Hence, they have a complex and highly regulated machinery to handle oxidative changes. The dysregulation of this antioxidant machinery is associated with a wide range of neurodegenerative conditions. Therefore, we evaluated signaling alterations, synaptic properties and behavioral performance in 2 and 6-month-old heterozygous manganese superoxide dismutase knockout mice (SOD2+/- mice). We found that their low antioxidant capacity generated direct oxidative damage in proteins, lipids, and DNA. However, only 6-month-old heterozygous knockout mice presented behavioral impairments. On the other hand, synaptic plasticity, synaptic strength and NMDA receptor (NMDAR) dependent postsynaptic potentials were decreased in an age-dependent manner. We also analyzed the phosphorylation state of the NMDAR subunit GluN2B. We found that while the levels of GluN2B phosphorylated on tyrosine 1472 (synaptic form) remain unchanged, we detected increased levels of GluN2B phosphorylated on tyrosine 1336 (extrasynaptic form), establishing alterations in the synaptic/extrasynaptic ratio of GluN2B. Additionally, we found increased levels of two phosphatases associated with dephosphorylation of p-1472: striatal-enriched protein tyrosine phosphatase (STEP) and phosphatase and tensin homolog deleted on chromosome Ten (PTEN). Moreover, we found decreased levels of p-CREB, a master transcription factor activated by synaptic stimulation. In summary, we describe mechanisms by which glutamatergic synapses are altered under oxidative stress conditions. Our results uncovered new putative therapeutic targets for conditions where NMDAR downstream signaling is altered. This work also contributes to our understanding of processes such as synapse formation, learning, and memory in neuropathological conditions.

AB - In Alzheimer's disease (AD) tau protein hyperphosphorylation causes neurofibrillary tangle formation, microtubule instability and neurodegeneration. Determining the mechanism of tau hyperphosphorylation will provide a better understanding of AD pathology. Cystatin C (CysC) is a risk factor for late-onset AD and its level is upregulated in the brains of AD patients. The role of CysC is AD pathogenesis is not known. In this study, we found that CysC level is upregulated in 3xTg-AD mouse brain. We demonstrate that CysC does not affect cellular Abeta production. However, when overexpressed in neuron (NGF differentiated PC12 cells), CysC inhibits turnover of GSK3beta, promotes GSK3beta catalyzed tau phosphorylation at Ser396/404 and causes microtubule instability. Our data provide a novel insight into the role of CysC in AD pathogenesis. PMID- 29577986 TI - Prurigo Pigmentosa: An Itchy, Urticarial Eruption Confused for Food Allergy.

AB - Baylisascaris procyonis is a nematode of significant concern to public and domestic animal health as well as wildlife management. The population genetics of B. procyonis is poorly understood. To gain insights into patterns of genetic diversity within (infrapopulation level) and among (component population level) raccoon (Procyon lotor) hosts, and specifically to assess the relative importance of indirect and direct transmission of the parasite for explaining observed population structure, we collected 69 B. procyonis from 17 wild raccoons inhabiting five counties in Missouri and Arkansas, USA. Informative regions of mitochondrial (CO1, CO2) and nuclear (28S, ITS2) genes were amplified and the distribution and genetic variability of these genes were assessed within and across raccoons. Concatenation of the CO1 and CO2 mtDNA sequences resulted in 5 unique haplotypes, with haplotype diversity 0.456 +/- 0.068. The most common haplotype occurred in 94% of raccoons and 72.5% of B. procyonis. Sequences for 28S rDNA revealed four unique nuclear genotypes, the most common found in 100% of raccoons and 82.6% of B. procyonis. ITS2 genotypes were assessed using fragment analysis, and there was a 1:1 correspondence between 28S and ITS-2 genotypes. Infrapopulation variation in haplotypes and genotypes was high and virtually all hosts infected with multiple sequenced nematodes also harbored multiple haplotypes and genotypes. There was a positive relationship between the size of the analyzed infrapopulation (i.e., the number of nematodes analyzed) and the number of haplotypes identified in an individual. Collectively this work emphasizes the importance of indirect transmission in the lifecycle to this parasite.

AB - BACKGROUND: The clinical manifestations of Group A streptococcus (GAS) - (Streptococcus pyogenes) are diverse, ranging from asymptomatic colonisation to devastating invasive disease. Maternity related clusters of invasive Group A streptococcus (iGAS) infection are complex to investigate and control, especially if recurrent. AIM: We report on the investigation into three episodes of emm 75 GAS/iGAS infection in maternity patients at one hospital site over a 4 year period, two with monophyletic ancestry. METHODS: The episodes are described, together with whole genome sequence isolate analyses. Single nucleotide polymorphism differences were compared with contemporaneous emm 75 genomes. FINDINGS: Seven mothers had GAS/iGAS in over a 4 year period, emm 75, S.pyogenes and one had iGAS (in year 4) emm 3, S.pyogenes (subsequently discounted as linked). Three (clinical/screening samples) of the seven babies of emm 75 positive mothers and 3 screened healthcare workers were positive for GAS emm 75. Whole genome sequence similarity suggested a shared ancestral lineage and suggested a common source transmission but directionality of transmission cannot be inferred. However the findings indicate that persistence of a particular clone in a given setting may be long-term. CONCLUSIONS: Occupational health procedures were enhanced, staff were screened and antibiotic therapy provided to GAS positive staff and patients. The definitive source of infection could not be identified, although staff/patient transmission is the most likely route. The pattern of clonal GAS transmission over 4 years suggests long-term persistence of GAS may have occurred. PMID- 29577991 TI - Effect of an exfoliating skincare regimen on the numbers of epithelial squames on the skin of operating theatre staff, studied by surface microscopy. AB - BACKGROUND: The shedding of epithelial squames (skin scales) by staff in operating theatre air is an important source of deep infection following joint replacement surgery. This is a serious complication, resulting in significant morbidity for the patient and substantial cost implications for healthcare systems. Much effort has been put into providing clean air in operating theatres, yet little attention has been given to reducing the shedding of surface skin scales at source. AIM: To develop a novel method for calculating surface skin scale density using surface microscopy, and to use it to evaluate the effect of a skincare regimen on operating theatre staff. METHODS: Surface microscopy with Z stacked imaging was used to visualize the effect of a skincare regimen involving three stages: washing with soap; exfoliation; and application of emollient. A USB microscope was then used in a field study to take images of the skin of operating theatre staff who applied the regimen to one lower limb the night before testing. The other limb was used as a control. Two blinded assessors analysed scale density. RESULTS: Z-stack images from the surface microscope enabled observations of the skincare regimen. The USB microscope also provided adequate images that enabled assessment of skin scale density. In the operating theatre staff, a 72.1% reduction in visible skin scales was observed following application of the skincare regimen. CONCLUSIONS: Further work is required to demonstrate how this effect correlates with dispersion of skin particles in a cleanroom, and subsequently in live operating theatre studies.

AB - BACKGROUND: At neonatal intensive care units, sepsis due to Gram-negative bacteria is an important cause of morbidity and mortality. The benefits of routine microbiological screening of neonatal body surface to predict and prevent sepsis are controversial. AIM: To evaluate the prognostic value of neonatal body surface screening for colonization with Gram-negative bacteria for the prediction of late-onset sepsis. METHODS: A systematic review was performed, including studies of any design that reported data to calculate prognostic accuracy of surface screening for the prediction of late-onset sepsis. Risk of bias was assessed and a meta-analysis performed. Evidence quality was appraised using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. FINDINGS: Eight studies (all cohort design) were identified as eligible. Studies were performed in six countries in Europe, Asia, and North America and comprised a total of 4829 participants. All studies were at high risk of bias. Pooled sensitivity of body surface screening to predict late-onset sepsis was 41% (95% confidence interval: 17-70), whereas pooled specificity was 56% (34-76) (hierarchical summary receiver operating characteristics (HSROC) model). Subgroup analyses showed higher pooled estimates for specificity but not sensitivity when screening focused on Escherichia coli or Klebsiella pneumoniae. GRADE evidence quality was very low. CONCLUSION: Limited evidence of very low quality exists regarding the prognostic value of neonatal screening for late onset sepsis. Carefully planned and conducted prospective studies, including randomized trials, are needed to clarify the potential value of this measure for the prediction and prevention of late-onset sepsis. PMID- 29577994 TI - Acinetobacter pittii isolated more frequently than Acinetobacter baumannii in blood cultures: the experience of a French hospital. AB - This study assessed the characteristics of hospital-acquired Acinetobacter calcoaceticus-Acinetobacter baumannii complex bloodstream infections (BSI). From 2010 to 2017, A. calcoaceticus-A. baumannii complex BSI were investigated. Of 73 cases, 54.8% were associated with Acinetobacter pittii, 39.7% with Acinetobacter baumannii and 5.5% with Acinetobacter nosocomialis. Multi-drug-resistant isolates were significantly higher in A. baumannii BSI. Thirty-day mortality was no different between A. baumannii or non-baumannii A. calcoaceticus-A. baumannii complex BSI. In contrast with other studies, this study found that most hospital acquired A. calcoaceticus-A. baumannii complex BSI were associated with non baumannii A. calcoaceticus-A. baumannii complex species. This study found that these species were important hospital-acquired pathogens, and emphasizes the importance of A. calcoaceticus-A. baumannii complex species identification.

AB - Following peripheral nerve injury, Schwann Cells (SCs) undergo dedifferentiation, proliferation, migration, and remyelination. Recent works demonstrated the importance of the short non-coding RNA (miRNAs) in SC dedifferentiation and remyelination after nerve injury. Previously, we found some miRNAs like miR-9, miR-221, miR-222 and miR-182 could regulate the proliferation and migration of SCs. Therefore, it is imperative to ask whether these miRNAs could regulate the myelination of SCs. Here we demonstrated that miR-221-3p could inhibit the myelination of SCs when co-cultured with dorsal root ganglion cells in vitro. In addition, NGF1-A binding protein 1 (Nab1) which was essential for SCs myelination could be downregulated by miR-221-3p. Suppressing the expression of Nab1 could reverse the promotion of miR-221-3p antagomir on SC myelination. The effects of miR-221-3p on SC myelination might be used to improve peripheral nerve regeneration, thus offering a new approach to peripheral nerve repair. PMID- 29577997 TI - Memory for Random Time Patterns in Audition, Touch, and Vision. AB - Perception deals with temporal sequences of events, like series of phonemes for audition, dynamic changes in pressure for touch textures, or moving objects for vision. Memory processes are thus needed to make sense of the temporal patterning of sensory information. Recently, we have shown that auditory temporal patterns could be learned rapidly and incidentally with repeated exposure [Kang et al., 2017]. Here, we tested whether rapid incidental learning of temporal patterns was specific to audition, or if it was a more general property of sensory systems. We used a same behavioral task in three modalities: audition, touch, and vision, for stimuli having identical temporal statistics. Participants were presented with sequences of acoustic pulses for audition, motion pulses to the fingertips for touch, or light pulses for vision. Pulses were randomly and irregularly spaced, with all inter-pulse intervals in the sub-second range and all constrained to be longer than the temporal acuity in any modality. This led to pulse sequences with an average inter-pulse interval of 166 ms, a minimum inter-pulse interval of 60 ms, and a total duration of 1.2 s. Results showed that, if a random temporal pattern re-occurred at random times during an experimental block, it was rapidly learned, whatever the sensory modality. Moreover, patterns first learned in the auditory modality displayed transfer of learning to either touch or vision. This suggests that sensory systems may be exquisitely tuned to incidentally learn re occurring temporal patterns, with possible cross-talk between the senses. PMID- 29577998 TI - Dual-task Interference Disrupts Parkinson's Gait Across Multiple Cognitive Domains. AB - Gait dysfunction, a hallmark of Parkinson's disease, contributes to a relatively high incidence of falling. Gait function is further diminished during the performance of a motor-cognitive task (i.e., dual-task). It is unclear if Parkinson's disease-related dual-task deficits are related to a specific area of cognitive function or are the result of a more global decline in executive function. The aim of this project was to systematically evaluate gait performance to determine if gait dysfunction is restricted to certain types of executive function or a global phenomenon in individuals with Parkinson's disease. Twenty three individuals with mild-moderate Parkinson's disease completed a series of dual-task conditions in which gait was paired with cognitive tasks requiring: working memory (0, 1, and 2-back), attention and problem solving (serial-7 subtraction), verbal memory (digit recall), semantic memory (Controlled Oral Word Association) and information processing speed (visual Stroop test). The results demonstrate that individuals with mild-moderate Parkinson's disease have a generalized worsening of spatial-temporal gait parameters regardless of the specific cognitive demand being performed concurrently. Overall, gait velocity decreased (p < 0.01) and stride and stance time both increased (p < 0.01) across all cognitive conditions. The attention and problem solving task resulted in the greatest number of gait parameter decrements. Results indicated that performance on cognitive tasks remained unchanged from single-task to dual-task conditions. Diminished gait performance under dual-task conditions across different cognitive function domains suggests a global Parkinson's disease-related deficit in information processing and regulation of gait. PMID- 29578000 TI - Monkey extensor digitorum communis motoneuron pool: Proximal dendritic trees and small motoneurons. AB - Transverse sections of the monkey cervical spinal cord from a previous study (Jenny and Inukai, 1983) were reanalyzed using Neurolucida to create a three dimensional display of extensor digitorum communis (EDC) motoneurons and proximal dendrites that had been labeled with horse radish peroxidase (HRP). The EDC motoneuron pool was located primarily in the C8 and T1 segments of the spinal cord. Small motoneurons (cell body areas less than 500 MUm2 and presumed to be gamma motoneurons) comprised about ten percent of the motoneurons and were located throughout the length of the motoneuron pool. Most small motoneurons were oblong in shape and had one or two major dendrites originating from the cell body in the transverse plane of section. The majority of the HRP labeled dendritic trees were directed either superiorly, dorsal-medially to the mid zone area between the base of the dorsal horn and the upper portion of the ventral horn, or medially to the ventromedial gray matter. The longer HRP labeled dendrites usually continued in the same radial direction as when originating from the cell body. As such we considered the radial direction of the longer proximal HRP labeled dendrites to be a reasonable estimate of the radial direction of the more distal dendritic tree. Our data suggest that the motoneuron dendritic tree as seen in transverse section has direction-oriented dendrites that extend toward functional terminal regions. PMID- 29577999 TI - Acute stress alters the rates of degradation of cardiac muscle proteins. AB - : Stressful experiences can have detrimental effects on many aspects of health and wellbeing. The zebrafish (Danio rerio) is a widely used model for stress research and a stress phenotype can be induced by manipulating the environmental conditions and social interactions. In this study we have combined a zebrafish stress model with the measurement of degradation rates of soluble cardiac muscle proteins. The results showed that the greater the stress response in the zebrafish the lower the level of overall protein degradation. On comparing the rates of degradation for individual proteins it was found that four main pathways were altered in response to stress conditions with decreased degradation for proteins involved in glucose metabolism, gluconeogenesis, the ubiquitin proteasome system (UPS) and peroxisomal proliferator-activated receptor (PPAR) signalling pathways. Taken together, these data indicate that under stress conditions zebrafish preserve cardiac muscle proteins required for the 'fight or flight' response together with proteins that play a role in stress mitigation. SIGNIFICANCE: This study is the first to investigate the impact of stressful experiences on the dynamics of protein turnover in cardiac muscle. Using an established zebrafish model of human stress it has been possible to map key pathways at the protein level. The results show that the rates of degradation of cardiac proteins involved in glucose metabolism, UPS activity, hypoxia and PPAR signalling are decreased in stressed zebrafish. These findings indicate that proteins involved in the 'fight or flight' response to stress are conserved by the heart together with proteins that play a role in stress mitigation. This work provides the basis for more detailed investigations aimed at understanding the molecular effects of stress, which has implications for human health and disease.

AB - Royal Jelly (RJ) is a unique substance obtained from bees that has been used widely in European and Asian traditional medicine for its potential to prevent signs of aging through its antioxidative, anti-inflammatory, anti-hyperglycemic and anti-hypercholesterolemic properties. We recently reported an enhancement in spatial memory along with changes in monoaminergic transmission in aged rats after chronic RJ administration. Here, we aim to further explore the action of RJ on central nervous system activity by examining levels of amino acids in selected brain structures of aged male Wistar rats following 2-months of Greek RJ administration. RJ powder was previously chemically characterized and given orally (50 or 100 mg of powder/kg b.w./day) by gastric gavage. The concentrations of amino acids (alanine, aspartic acid, gamma-aminobutyric acid, glutamic acid, histidine and taurine) in the brain regions examined (prefrontal cortex, hippocampus, striatum and hypothalamus) were quantified using HPLC. We also examined basic biochemical parameters of renal and hepatic activity, as damage of these organs could potentially explain the changes in brain function and behavior. Upon biochemical examination, a decrease in the concentration of gamma aminobutyric acid was observed in both the striatum and hypothalamus. Liver and kidney functions were not changed by chronic RJ-administration. Our results provide insight toward understanding the mechanism of action of RJ and its effects on neurotransmission in the central nervous system. PMID- 29578002 TI - Inhibition of microRNA-34a protects against propofol anesthesia-induced neurotoxicity and cognitive dysfunction via the MAPK/ERK signaling pathway. AB - AIM: To investigate the protective effect of microRNA-34a (miR-34a) on propofol induced neurotoxicity and cognitive dysfunction. METHODS: After SH-SY5Y cells were treated with propofol to induce neurotoxicity, microRNA-34a mimics and inhibitors were transfected into the cells. The expression of apoptosis-related genes and the proteins were measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blot. Sprague-Dawley (SD) rats received intraperitoneal injections of propofol, and were treated with microRNA 34a mimics and lentivirus-mediated microRNA-34a inhibitors. The Morris water maze (MWM) test was used to detect changes in motor function. RESULTS: Propofol anesthesia had an adverse effect on cell survival due to the increased expression of apoptosis-related genes such as cleaved caspase-3/8 and Bax, which was accompanied by reduced expression of ERK1/2, pERK1/2, and phosphorylated NF kappaB p65 both in vivo and in vitro. Unexpectedly, microRNA-34a was upregulated after propofol treatment, and the inhibitors protected the SH-SY5Y cells from propofol-induced apoptosis. The microRNA-34a inhibitor suppressed the apoptosis induced effects of propofol. This protection may have been partly diminished by PD98059, a MAPK kinase inhibitor. MicroRNA-34a inhibited or reverted the reduced expression of ERK1/2 and upregulated the expression of p-CREB significantly and specifically. Additionally, the microRNA inhibitors improved the learning and memory functions of animals suffering from neurologic impairment due to propofol treatment and reduced cell apoptosis in the hippocampus. CONCLUSION: microRNA-34a could improve anesthesia-induced cognitive dysfunction by suppressing cell apoptosis and recovering the expression of genes associated with the MAPK/ERK signaling pathway.

AB - Epileptic seizures are the main clinical manifestation of low-grade astrocytoma. Voltage-gated sodium channels (VGSCs) play a crucial role in epilepsy. Until now, the role of VGSCs and the relationships between calmodulin (CaM)/CaM-dependent protein kinase II (CaMKII) and VGSCs in low-grade astrocytoma have not been demonstrated. In our study, the protein expression of NaV1.3, NaV1.6 and CaM was significantly increased in the tumor compared to control tissue, while the level of p-CaMKII/CaMKII was significantly decreased in the tumor group as determined by Western Blotting and immunohistochemistry. Furthermore, double-labeling immunofluorescence results showed that NaV1.3/NaV1.6 and CaM co-localization was significantly increased in the tumor group compared to control tissue. This study represents the first evidence of the abnormal changes in VGSCs subtypes and CaM/CaMKII pathway in human brain low-grade astrocytoma, providing new potential targets for molecular therapies of this disease. PMID- 29578004 TI - The triple monoamine re-uptake inhibitor DOV 216,303 promotes functional recovery after spinal cord contusion injury in mice. AB - Serotonin, noradrenaline and dopamine are important neuromodulators for locomotion in the spinal cord. Disruption of descending axons after spinal cord injury resulted in reduction of excitatory and neuromodulatory inputs to spinal neurons for locomotion. Receptor agonists or reuptake inhibitors for these neuromodulators have been shown to be beneficial in incomplete spinal cord injury. In this study, we tested a triple re-uptake inhibitor, DOV 216,303, for its ability to affect motor function recovery after spinal cord injury in mice. We impacted C57 mouse spinal cord at the T11 vertebral level and administered vehicle or DOV 216,303 at 10 mg/kg, b.i.d via intraperitoneal injections for 7 days. We monitored motor function with the Basso Mouse Scale for locomotion for 4 weeks. Spinal cords were harvested and histological examinations were performed to assess tissue sparing and lesion severity. Results showed that DOV 216,303 treated mice recovered significantly better than vehicle treated mice starting at 14 days post injury until the end of the survival period. Lesion size of the DOV 216,303 treated mice was also smaller compared to that of vehicle treated mice. This study suggests DOV 216,303 as a potential therapeutic after spinal cord injury warrants further investigation.

AB - Chitosan is an abundant non-toxic, biodegradable polymer with versatile applications. It is a linear amino polysaccharide obtained from crustacean shells. The chitosan nanoparticles (ChNP) prepared by ionic gelation of chitosan has greater activity owing to its small size. ChNP has been proved to be effective in controlling plants diseases. In this work, we have endeavoured to study the antifungal and antioxidant activity of ChNP and use of ChNP as a vegetable coating material. The activity of ChNP against selected plant pathogens Rhizoctonia solani, Fusarium oxysporum, Collectotrichum acutatum, and Phytophthora infestans were studied along with a brief account of its mechanism of action. The antioxidant activity of ChNP was also analysed. The ability of ChNP as a coating material to improve the shelf life of tomato, chilly and brinjal was also studied. The cytotoxicity effect of ChNP against L929 fibroblast cells was studied. ChNP had good antifungal activity against all selected pathogens compared to Amphotericin B. Significant antioxidant activity was obtained. The vegetables coated with different concentrations of ChNP (1%, 2%, 3%, 4% and 5%) showed decreased weight loss compared to uncoated control. ChNP was shown to have decreased cytotoxicity thus making it an ideal antifungal, antioxidant and coating agent.

AB - The FeS2 Quantum Dots (QDs) decorated SiO2 nanostructure were prepared by hydrothermal synthesis method. Chitosan and polypyrrole as polymers were used for the immobilization process. The characteristic structure of prepared samples was analyzed using several techniques such as X-ray diffraction, scanning and transmittance electron microscopy, photoluminescence and UV-vis spectroscopy. The mean crystallite sizes of FeS2 QDs/SiO2 nanocomposites, FeS2 QDs/SiO2-chitosan nanocomposites and FeS2 QDs/SiO2-polypyrrole nanohybrids are 56.12, 76.38, and 83.24nm, respectively. The band gap energy of FeS2 QDs/SiO2 nanocomposites, FeS2 QDs/SiO2-chitosan nanocomposites and FeS2 QDs/SiO2-polypyrrole nanohybrids were found out to be 3.0, 2.8, and 2.7eV, respectively. The photocatalysis properties were investigated by degradation of ampicillin under UV light illumination. The effect of experimental variables, such as, pH and time, on photo-degradation efficiency was studied. The results show that the three prepared samples nanopowders under UV light was in pH3 at 60min. As it could be seen that the amount of ampicillin degradation was increased with the loading of FeS2 QDs on SiO2 and FeS2 QDs/SiO2 on chitosan nanoparticles and polypyrrole nanofiber. The antibacterial experiment was investigated under visible light illumination and the FeS2 QDs/SiO2-chitosan nanocomposites and FeS2 QDs/SiO2-polypyrrole nanohybrids demonstrate good antibacterial compared to FeS2 QDs/SiO2 nanocomposites. PMID- 29578007 TI - Grafted sesbania gum: A novel derivative for sugarcane juice clarification. AB - This work describes the significance of graft copolymer induced flocculation process in sugarcane juice clarification. The naturally occurring cinnamic acid has been successfully incorporated into the structure of sesbania gum through microwave assisted technique (hybrid of conventional and microwave based method) to develop novel, non-toxic, eco-friendly product with highly extended structure. The customized structure of gum derivative has been characterized by a number of modern techniques like 13C NMR, FTIR, SEM, XRD, TGA, DSC, elemental and viscometric analysis. The separation of suspended colloidal impurities from cane juice has been achieved through the application of synthesized gum derivative as a flocculant. The clarification performance of the graft copolymer has been evaluated in terms of turbidity, absorbance, and degree brix ( degrees bx). The flocculant exhibited maximum efficiency at 1.0ppm (optimized dose) without altering the nutritional parameters (% sugar content). The clarified juice thus obtained may be used as a beverage for direct consumption or for the manufacture of white sugar. PMID- 29578008 TI - Surface modification of electrospun PVA/chitosan nanofibers by dielectric barrier discharge plasma at atmospheric pressure and studies of their mechanical properties and biocompatibility. AB - In this paper, surface of electrospun PVA/Cs nanofibers is modified using dielectric barrier discharge (DBD) plasma and the relationship between the observed mechanical properties and biocompatibility of the nanofibers and plasma induced surface properties is discussed. Plasma treatment of electrospun PVA/Cs nanofibers is carried out with both inert (argon, Ar) and reactive (oxygen, O2) gases at atmospheric pressure. Incorporation of oxygen-containing polar functional groups on the surface of Ar-plasma treated (PVA/Cs/Ar) and O2-plasma treated (PVA/Cs/O2) nanofibers and increase in surface roughness contribute to the improvement of surface wettability and the decrease of contact angle with water of the nanofibers. Both PVA/Cs/Ar and PVA/Cs/O2 nanofibers show high tensile strength (11.6-15.6%) and Young's modulus (33.8-37.3%) as compared to the untreated one. Experimental results show that in terms of haemolytic activity the PVA/Cs/Ar and PVA/Cs/O2 nanofibers do not cause structural changes of blood cells and meet the biocompatibility requirements for blood-contacting polymeric materials. MTT cell viability results further reveals improvement in biocompatibility of PVA/Cs nanofibers after Ar and O2 plasma treatment. The results suggest that DBD plasma treated electrospun PVA/Cs nanofibers have the potential to be used as wound dressing and scaffolds for tissue engineering.

PMID- 29578010 TI - Characterization, optimization and stability studies on Candida rugosa lipase supported on nanocellulose reinforced chitosan prepared from oil palm biomass. AB - The contribution of chitosan/nanocellulose (CS-NC) to the enzymatic activity of Candida rugosa lipase covalently bound on the surface of CS-NC (CRL/CS-NC) was investigated. Cellulosic material from oil palm frond leaves (OPFL) were bleached, alkaline treated and acid hydrolyzed to obtain the purified NC and used as nano-fillers in CS. XRD, Raman spectroscopy and optical fluorescence microscopic analyses revealed existence of strong hydrogen bonds between CS and the NC nanofillers. The CRLs were successfully conjugated to the surface of the CS-NC supports via imine bonds that occurred through a Schiff's based mechanism. Process parameters for the immobilization of CRL were assessed for factors temperature, concentration of glutaraldehyde and pH, to afford the highest enzyme activity to achieve maximum conversion of butyl butyrate within 3h of incubation. Conversion as high as 88% was reached under an optimized condition of 25 degrees C, 0.3% glutaraldehyde concentration and buffer at pH7. Thermal stability of CRL/CS-NCs was 1.5-fold greater than that of free CRL, with biocatalysts reusability for up to 8 successive esterification cycles. This research provides a promising approach for expanding the use of NC from OPFL for enhancing enzyme activity in favour of an alternative eco-friendly means to synthesize butyl butyrate. PMID- 29578011 TI - Cross-linked enzyme aggregates of alginate lyase: A systematic engineered approach to controlled degradation of alginate hydrogel. AB - An enzyme aggregate of alginate lyase (EC 4.2.2.3) from flavobactierium was prepared using ammonium sulfate. The resultant aggregates upon cross-linking with glutaraldehyde produced insoluble and catalytically active cross-linked enzyme aggregate (CLEA) enzyme. The catalytic activity and stability of the cross-linked enzyme aggregate of alginate lyase (CLEA-AL) was studied in the presence of various pH, temperatures and organic solvents. Reusability, storage stability and surface morphology of the CLEA-AL were also studied. The native enzyme and CLEA AL exhibited maximum enzyme activity at pH of 6.3 and at a temperature of 40 degrees C. The CLEA-AL has good stability in nonpolar organic solvents and is thermally stable up to 50 degrees C over a period of 8h. By encapsulating CLEA-AL into alginate hydrogel, we demonstrate that alginate hydrogels can be enzymatically degraded in a controlled fashion. The results also showed that degradation of alginate hydrogel with CLEA-AL incorporated beads is slower than native enzyme and therefore, CLEA-AL can be used for controlled degradation and release of various biologics from the degrading gel. PMID- 29578012 TI - Structural characterization and immunomodulating activities of a novel polysaccharide from Nervilia fordii. AB - Nervilia fordii (Hance) Schltr. has been widely used as a medicinal and edible herb in Southwest China and Southeast Asia. In this study, NFP-1, a new water soluble polysaccharidewith a purity of 97.8%, was purified from water extract of Nervilia fordii by DEAE-cellulose and Sephadex G-100 chromatography. NFP-1 has a relative molecular weight of 950 kDa determined by high performance gel permeation chromatography (HPGPC). Its monosaccharide compositions were analyzed by high performance liquid chromatography (HPLC) after pre-column derivatizing its hydrolysate with 1-phenyl-3-methyl-5-pyrazolone (PMP). NFP-1 mainly consists of galactose, arabinose, rhamnose, and galacturonic acid. Based on FT-IR, methylation and GC-MS analysis, and NMR, the structure unit of NFP-1 was established as ->4)-alpha-Rhap-(2-> 4)-alpha-GalpA-(1->2)-alpha-Rhap-(1->2)-alpha Rhap-(4->1)-beta-Galp-T containing two branch chains of ->2,4)-alpha-Rhap-(1->5) alpha-Araf-(1->3)-alpha-Araf-(1->, and ->2,4)-alpha-Rhap-(1->4)-beta-Galp-(1->. The immunomodulatory assays revealed the dual-functionalities of NFP-1. NFP-1 could significantly induce the secretion of nitric oxide (NO), and promote the secretions of TNF-alpha, IL-6, and IL-1beta in RAW264.7 macrophages. NFP-1 could also significantly inhibit the production of NO, depress the secretions of TNF alpha, IL-6 and IL-1beta in RAW264.7 macrophages activated by lipopolysaccharide (LPS), and promote the production of IL-10 meanwhile. Our study suggested that Nervilia fordii could be an ideal medicinal or functional food due to its dual immunomodulatory activities. PMID- 29578013 TI - Properties of cellulose/Antarctic krill protein composite fibers prepared in different coagulation baths. AB - In this paper, cellulose/Antarctic krill protein composite fibers were obtained by wet spinning. The raw materials were recyclable cellulose (C) and Antarctic krill protein (AKP), while the solvent was an aqueous solution containing 7wt% NaOH and 12wt% urea, which is eco-friendly. The fiber was stretched in a coagulation bath containing H2SO4 and Na2SO4. The effects of coagulation at different bath concentrations on the mechanical performance, crystallinity, and morphology of the C/AKP composite fibers were studied systematically. The break strength firstly increased and then decreased with an increase in the concentration of the bath. At a coagulation bath concentration of H2SO2/Na2SO4 (12wt%/12wt%), the crystallinity was 15.16%. Scanning electron microscopy (SEM) observations revealed the presence of grooves on the fiber surface. The type and percentage of hydrogen bonds in the C/AKP composite fibers were analyzed by Fourier transform infrared spectroscopy (FT-IR). On the basis of the obtained results, we finally optimized the coagulation bath composition and concentration. PMID- 29578014 TI - Development of a reusable and sustainable biocatalyst by immobilization of soybean peroxidase onto magnetic adsorbent. AB - In this work we synthesized an activated carbon/magnetite composite by a simple co-precipitation method. The activated carbon (AC) was synthesized from the solid waste obtained in the extraction process of the peroxidase enzyme and the magnetic composite was used as support for the immobilization of soybean peroxidase (SP). After the determination of the optimal immobilization parameters, a 100% yield was achieved under the following conditions: support:enzyme proportion of 1.0:0.05 g, equilibration time of 7 h, pH 3.0 (citrate buffer phosphate 0.1 mol L-1) and temperature of 50 degrees C. The determination of pH to the point of zero charge was also done to assist in the understanding of the immobilization process at different pH values. Several characterization techniques were used, such as thermogravimetric analysis, elemental analysis composition, X-ray powder diffraction, Fourier transform infrared spectroscopy and Scanning electron microscopy. The biocatalyst presented excellent operational stability and was reused for 11 consecutive cycles. The magnetic properties inserted in the AC contributed to the removal of the biocatalyst from the reaction medium without interfering in the adsorptive characteristics of the AC. Thus, the activated carbon/magnetite composite can be applied to different research fields with high performance. PMID- 29578015 TI - Shelf-life of smoked eel fillets treated with chitosan or thyme oil. AB - The present study examined the effect of natural antimicrobials: Chitosan, thyme oil and their combination, on the shelf-life of smoked eel fillets stored under vacuum packaging (VP) at 4 degrees C. Based on sensory odor data smoked eel fillets had a shelf-life of 35 (control), 42 (thyme treated and>49 (thyme, chitosan-thyme treated) days. The thiobarbituric acid value (TBA) value of the control eel sample was significantly higher than the chitosan-thyme-treated eel samples. The use of chitosan singly, or in combination with thyme oil reduced lipid oxidation (TBA) of the smoked eel samples. A trimethylamine nitrogen (TMA N) value of 10mgN/100g, could be suggested as an indication of smoked eel spoilage initiation. Control and treated eel reached total volatile basic nitrogen (TVB-N) values of 13.1-31.5mgN/100g below the maximum permissible level of TVB-N in fish and fishery products. Eel samples reached the value of 7.0logcfu/g (Total Plate Count, TPC) on days 35 (smoked) and 42 (thyme treated), whereas both chitosan and chitosan-thyme treated eel samples never reached this limit value. Results of our study show thyme or chitosan (singly, or in combination) inhibit the growth of mesophilic bacteria and extend the shelf-life of smoked eel. PMID- 29578016 TI - Antioxidant and antimicrobial potential of polysaccharides sequentially extracted from Polygonatum cyrtonema Hua. AB - We examined the antioxidant and antimicrobial attributes of Polygonatum cyrtonema Hua polysaccharides (HBSS, CHSS, DASS, CASS). The UV spectra and FT-IR results showed the purity and acidic nature of polysaccharides with beta-configurations. DASS (78.585% hydroxyl radical scavenging, 92.794% ABTS radical scavenging, 75.648% DPPH radical scavenging activity, 0.582 reducing power and 98.721% Fe2+ chelation at 5mg/mL) possessed the best antioxidant potential; while, HBSS (21.113% hydroxyl radical scavenging, 14.412% ABTS radical scavenging, 28.005% DPPH radical scavenging activity, 0.285 reducing power and 48.969% Fe2+ chelation at 5mg/mL) was observed with the lowest antioxidant action. The bacterial inhibition effect of four PCHPs on Gram-positive organisms (B. subtilis and S. aureus with the maximum inhibitory diameters of 18.9 and 15.8mm, respectively) was better than that of Gram-negative bacteria (E. coli and S. typhimurium with the maximum inhibitory diameters of 10.9 and 8.4mm, respectively). The bacterial sensitivity was observed in the following order: B. subtilis>S. aureus>E. coli>S. typhimurium. The trend of antibacterial action of PCHPs was in following order: DASS>CHSS>CASS>HBSS. DASS can be considered as natural anti-oxidant as well as spoilage inhibitors to enhance the nutritive and functional values of various foods. PMID- 29578017 TI - Nanostructured lipid carrier-based pH and temperature dual-responsive hydrogel composed of carboxymethyl chitosan and poloxamer for drug delivery. AB - The aim of this study was to develop a novel nanostructured lipid carrier (NLC) based dual-responsive hydrogel for ocular drug delivery of quercetin (QN). NLC loaded with quercetin (QN-NLC) was prepared using melt-emulsification combined with ultra-sonication technique. A three-factor five-level central composite design (CCD) was employed to optimize the formulation of QN-NLC. The optimized QN NLC presented a particle size of 75.54nm with narrow size distribution and high encapsulation efficiency (97.14%).QN-NLC was characterized by TEM and DSC. In addition, a pH and temperature dual-responsive hydrogel composed of carboxymethyl chitosan (CMCS) and poloxamer 407(F127) was constructed by a cross-linking reaction with a naturally occurring nontoxic crosslinking agent genipin (GP). FT IR was employed to demonstrate that F127/CMCS hydrogel was successfully synthesized. The results of SEM analysis and swelling experiments indicated that F127/CMCS hydrogel was both temperature-responsive and pH-responsive. From the results of In vitro release studies, dual temperature and pH responsiveness of the hydrogel was demonstrated, and 80.52% of total quercetin was released from the QN-NLC based hydrogel (QN-NLC-Gel) within 3days, revealing QN-NLC-Gel released drug sustainably. Taken together, the developed NLC-based hydrogel is a promising drug delivery system for the ophthalmic application. PMID- 29578018 TI - Genotoxicity and osteogenic potential of sulfated polysaccharides from Caulerpa prolifera seaweed. AB - Marine algae are sources of novel bioactive molecules and present a great potential for biotechnological and biomedical applications. Although green algae are the least studied type of seaweed, several of their biological activities have already been described. Here, we investigated the osteogenic potential of Sulfated Polysaccharide (SP)-enriched samples extracted from the green seaweed Caulerpa prolifera on human mesenchymal stem cells isolated from Wharton jelly (hMSC-WJ). In addition, the potential genotoxicity of these SPs was determined by cytokinesis-block micronucleus (CBMN) assay. SP-enriched samples did not show significant cytotoxicity towards hMSCs-WJ at a concentration of up to 10MUg/mL, and after 72h of exposure. SP enrichment also significantly increased alkaline phosphatase (ALP) activity, promoting calcium accumulation in the extracellular matrix. Among the SP-enriched samples, the CP0.5 subfraction (at 5MUg/mL) presented the most promising results. In this sample, ALP activity was increased approximately by 60%, and calcium accumulation was approximately 6-fold above the negative control, indicating high osteogenic potential. This subfraction also proved to be non-genotoxic, according to the CBMN assay, as it did not induce micronuclei. The results of this study highlight, for the first time, the potential of these SPs for the development of new therapies for bone regeneration. PMID- 29578019 TI - Preparation and characterization of chitosan-based antimicrobial active food packaging film incorporated with apple peel polyphenols. AB - In the present study, apple peel polyphenols (APP) were incorporated into chitosan (CS) to develop a novel functional film. Scanning electron microscopy, Fourier transform-infrared spectroscopy and thermogravimetric analyses were performed to study the structure, potential interaction and thermal stability of the prepared films. Physical properties including moisture content, density, color, opacity, water solubility, swelling ration and water vapor permeability were measured. The results revealed that addition of APP into CS significantly improved the physical properties of the film by increasing its thickness, density, solubility, opacity and swelling ratio whereas moisture content and water vapor permeability were decreased. Tensile strength and elongation at break of the CS-APP film with 1% APP was 16.48MPa and 13.33%, respectively, significantly lower than those for CS control film. Thermal stability of the prepared films was decreased while antioxidant and antimicrobial activities of the CS-based APP film were significantly increased. CS-APP film with 0.50% APP concentration exhibited good mechanical and antimicrobial properties, indicating that it could be developed as bio-composite food packaging material for the food industry. PMID- 29578020 TI - Molecular docking and in vitro studies of soap nut trypsin inhibitor (SNTI) against phospholipase A2 isoforms in therapeutic intervention of inflammatory diseases. AB - Therapeutic value of allelochemicals in inflammatory disorders and the potential drug targets need to be elucidated to alleviate tissue and vascular injury. Natural anti-inflammatory agents are known to cause minimal adverse effects. Presence of different secondary metabolites (allelochemicals), protease inhibitors like soap nut trypsin inhibitor (SNTI) from Sapindus trifoliatus and allied compounds from natural sources cannot be blithely ignored as natural therapeutics. In the present study, SNTI, a prospective protease inhibitor isolated from the seeds of Sapindus trifoliatus were subjected to docking against three isoforms of Phospholipase A2 (PLA2) molecules of the inflammatory pathways which are localized in the membrane, cytosol and pancreas. Eleven ligand molecules were selected from Sapindus trifoliatus and docked against membrane, cytosolic and pancreatic PLA2. Cytosolic PLA2 showed a strong inhibition by Kampferol, a secondary metabolite from seed endosperm of Sapindus trifoliatus. SNTI showed best interaction with membrane PLA2 in both in silico as well as in in vitro studies. SNTI showed IC50 value of 29.02 MUM in in vitro assay. Docking interaction profiles and in vitro studies validate selected molecules from Sapindus trifoliatus as immunomodulators and can mollify inflammatory responses. PMID- 29578021 TI - Biocompatible scaffolds based on natural polymers for regenerative medicine. AB - The chitosan and gelatine are commonly used biopolymers for the tissue engineering applications. In the previous methods for the cryogels synthesis, multistep preparation methods using toxic cross-linking agents such as glutaraldehyde are reported. Here, we present a two-step preparation method of gelatin macroporous cryogels and one-step preparation method of chitosan or gelatin cryogels. The physico-chemical properties of obtained scaffolds were characterized using FTIR, zeta potential, SEM and laser confocal microscopy. Non toxic and biodegradable cross-linking agents such as oxidized dextran and 1,1,3,3 tetramethoxypropane are utilized. The one-step chitosan cryogels had degradation degree ~2 times higher compared to the cryogels prepared with a two-step method i.e. reduced by borohydride. Scaffolds cross-linked by glutaraldehyde had about 40% viability, whereas nine various compositions of cryogels showed significantly higher viability (~80%) of fibroblast cells in vitro. The cryogels were obtained without using the harmful compounds and therefore can be used straightforward as biocompatible and biodegradable scaffolds for the cell culturing purposes and other biomedical applications. PMID- 29578022 TI - Compositional analysis of sulfated polysaccharides from sea cucumber (Stichopus japonicus) released by autolysis reaction. AB - Autolysis is not only a major reason for postharvest quality deterioration of sea cucumber, but also a promising alternative for exogenous protease to produce peptides or polysaccharides. However, little has been known about the effects of autolysis on bioactive polysaccharides of sea cucumber. Concerning the quality and safety of sea cucumber products involved autolysis reaction, the present study focused on the chemical composition of sulfated polysaccharides (SPs) released by autolysis reaction. Chemical analysis indicated that after 3-day autolysis 63% of sulfated polysaccharides were liberated but with protein chains at their reducing ends. Then the composition of SP obtained by autolysis (A-SP) was compared with that of total SPs (T-SP) via a series of analysis techniques, including FTIR, 1H NMR, HPLC and mass spectroscopy. As indicated by the results, fucan to fucosylated chondroitin sulfate ratio was found high in A-SP compared to T-SP, fucan with a lower molecular weight was the major fraction in A-SP, and the di-sulfated Fuc residue observed in T-SP was absent in A-SP. To conclude, A-SP differed greatly from T-SP in the chemical composition, suggesting possible changes on their bioactivities. PMID- 29578023 TI - Effect of organic additives on physiochemical properties and anti-oxidant release from chitosan-gelatin composite films to fatty food simulant. AB - Chitosan, gelatin and their blended films prepared and compared in some optical, physical and mechanical properties. The release rate of Gallic acid (GA) from the film to food fatty simulant studied. The chitosan- gelatin based films showed appropriate compatibility and desirable properties in comparison with singular gelatin and chitosan film. GA was added using different methods including simple addition, with two concentration of tween, with ethanol, with beta-Cyclodextrin (beta-CD) in physical mixture and encapsulated form. Incorporation of GA causes leads to formation of weak and dark samples. Use of beta-CD with GA decreased tensile strength (TS) significantly. Film samples with physical mixture of beta CD and GA indicated lower barrier properties against water vapor and release rate in comparison with their inclusion complex. Incorporation of tween 20, at low concentration leads to higher release rate, elongation at break (EB%) and water vapor permeability (WVP). Due to the lowest release rate observed for samples with ethanol as well as almost good (desirable) physical and mechanical properties, it could be appropriate candidate for fatty food packaging in long period. On the other hand, highest rate related to samples contained GA- beta-CD inclusion complex, which are suitable to higher anti-oxidant demands and short term protection. PMID- 29578024 TI - Stimulus-responsive zinc oxide-functionalized macromolecular humic acid nanocarrier for enhancement of antibacterial activity of ciprofloxacin hydrochloride. AB - Macromolecular of naturally occurring humic acid (HA) have garnered interest in the chemical, biological and medicine industry owing to their unique behavior, i.e., strong adsorptive and non-toxic nature. Here, we investigated the functionalization of organic (HA) with inorganic (ZnO) hybrid nanoparticles for topical and site-targeted delivery of ciprofloxacin by simple emulsification techniques. Ciprofloxacin (CIPRO)-encapsulated hybrid nanocarrier constitute an attractive novel drug delivery vehicle for sustained release of antibiotics to bacterial infection sites in an extended and controlled manner. The analytical characteristics of the designed system were thoroughly investigated by FTIR, XRD, SEM/EDAX, and TEM. The drug release of ciprofloxacin over 24h was 87.5%, 98.03%, 97.44%, and 97.24% for pH2.5, 5.5, 6.8, and 8.0, respectively. The antibacterial activities results confirmed that the CIPRO-encapsulated hybrid nanocarrier showed excellent growth inhibition against microorganisms. This hybrid nanocarrier loaded with antibiotics represents a promising approach for targeted and controlled drug delivery to infected sites. PMID- 29578026 TI - A subject-transfer framework for obviating inter- and intra-subject variability in EEG-based drowsiness detection. AB - Inter- and intra-subject variability pose a major challenge to decoding human brain activity in brain-computer interfaces (BCIs) based on non-invasive electroencephalogram (EEG). Conventionally, a time-consuming and laborious training procedure is performed on each new user to collect sufficient individualized data, hindering the applications of BCIs on monitoring brain states (e.g. drowsiness) in real-world settings. This study proposes applying hierarchical clustering to assess the inter- and intra-subject variability within a large-scale dataset of EEG collected in a simulated driving task, and validates the feasibility of transferring EEG-based drowsiness-detection models across subjects. A subject-transfer framework is thus developed for detecting drowsiness based on a large-scale model pool from other subjects and a small amount of alert baseline calibration data from a new user. The model pool ensures the availability of positive model transferring, whereas the alert baseline data serve as a selector of decoding models in the pool. Compared with the conventional within-subject approach, the proposed framework remarkably reduced the required calibration time for a new user by 90% (18.00 min-1.72 +/- 0.36 min) without compromising performance (p = 0.0910) when sufficient existing data are available. These findings suggest a practical pathway toward plug-and-play drowsiness detection and can ignite numerous real-world BCI applications. PMID- 29578025 TI - The role of the right superior temporal gyrus in stimulus-centered spatial processing. AB - Although emerging neuropsychological evidence supports the involvement of temporal areas, and in particular the right superior temporal gyrus (STG), in allocentric neglect deficits, the role of STG in healthy spatial processing remains elusive. While several functional brain imaging studies have demonstrated involvement of the STG in tasks involving explicit stimulus-centered judgments, prior rTMS studies targeting the right STG did not find the expected neglect-like rightward bias in size judgments using the conventional landmark task. The objective of the current study was to investigate whether disruption of the right STG using inhibitory repetitive transcranial magnetic stimulation (rTMS) could impact stimulus-centered, allocentric spatial processing in healthy individuals. A lateralized version of the landmark task was developed to accentuate the dissociation between viewer-centered and stimulus-centered reference frames. We predicted that inhibiting activity in the right STG would decrease accuracy because of induced rightward bias centered on the line stimulus irrespective of its viewer-centered or egocentric locations. Eleven healthy, right-handed adults underwent the lateralized landmark task. After viewing each stimulus, participants had to judge whether the line was bisected, or whether the left (left-long trials) or the right segment (right-long trials) of the line was longer. Participants repeated the task before (pre-rTMS) and after (post-rTMS) receiving 20 min of 1 Hz rTMS over the right STG, the right supramarginal gyrus (SMG), and the vertex (a control site) during three separate visits. Linear mixed models for binomial data were generated with either accuracy or judgment errors as dependent variables, to compare 1) performance across trial types (bisection, non-bisection), and 2) pre- vs. post-rTMS performance between the vertex and the STG and the vertex and the SMG. Line eccentricity (z = 4.31, p < 0.0001) and line bisection (z = 5.49, p < 0.0001) were significant predictors of accuracy. In the models comparing the effects of rTMS, a significant two-way interaction with STG (z = -3.09, p = 0.002) revealed a decrease in accuracy of 9.5% and an increase in errors of the right-long type by 10.7% on bisection trials, in both left and right viewer-centered locations. No significant changes in leftward errors were found. These findings suggested an induced stimulus-centered rightward bias in our participants after STG stimulation. Notably, accuracy or errors were not influenced by SMG stimulation compared to vertex. In line with our predictions, the findings provide compelling evidence for right STG's involvement in healthy stimulus-centered spatial processing. PMID- 29578027 TI - Distinct and overlapping fusiform activation to faces and food. AB - The fusiform cortex is a part of the ventral visual stream and is typically associated with face processing. Indeed, a subregion of the fusiform has been named the "fusiform face area" or FFA, based on its robust response to faces relative to other objects. In a separate literature, appetizing food has also been shown to activate bilateral fusiform cortex, yet no study to date has directly compared face and food responses within the same paradigm. Here, we use functional magnetic resonance imaging (fMRI) to compare face and food responses in ventral visual cortex and other regions that are typically associated with face processing. We present evidence that a region of the left fusiform cortex (typically associated with face processing) actually responds equally to faces and food. We go on to describe the similarities and differences in location of face- and food-responses in the fusiform, the relationship of fusiform activation to body mass index (BMI), and resting state connectivity of face- and food selective fusiform. Results are interpreted within a model in which motivational relevance or value influence fusiform response. PMID- 29578028 TI - Changes in alpha activity reveal that social opinion modulates attention allocation during face processing. AB - Participants' performance differs when conducting a task in the presence of a secondary individual, moreover the opinion the participant has of this individual also plays a role. Using EEG, we investigated how previous interactions with, and evaluations of, an avatar in virtual reality subsequently influenced attentional allocation to the face of that avatar. We focused on changes in the alpha activity as an index of attentional allocation. We found that the onset of an avatar's face whom the participant had developed a rapport with induced greater alpha suppression. This suggests greater attentional resources are allocated to the interacted-with avatars. The evaluative ratings of the avatar induced a U shaped change in alpha suppression, such that participants paid most attention when the avatar was rated as average. These results suggest that attentional allocation is an important element of how behaviour is altered in the presence of a secondary individual and is modulated by our opinion of that individual. PMID- 29578029 TI - UBO Detector - A cluster-based, fully automated pipeline for extracting white matter hyperintensities. AB - We present 'UBO Detector', a cluster-based, fully automated pipeline for extracting and calculating variables for regions of white matter hyperintensities (WMH) (available for download at https://cheba.unsw.edu.au/group/neuroimaging pipeline). It takes T1-weighted and fluid attenuated inversion recovery (FLAIR) scans as input, and SPM12 and FSL functions are utilised for pre-processing. The candidate clusters are then generated by FMRIB's Automated Segmentation Tool (FAST). A supervised machine learning algorithm, k-nearest neighbor (k-NN), is applied to determine whether the candidate clusters are WMH or non-WMH. UBO Detector generates both image and text (volumes and the number of WMH clusters) outputs for whole brain, periventricular, deep, and lobar WMH, as well as WMH in arterial territories. The computation time for each brain is approximately 15 min. We validated the performance of UBO Detector by showing a) high segmentation (similarity index (SI) = 0.848) and volumetric (intraclass correlation coefficient (ICC) = 0.985) agreement between the UBO Detector-derived and manually traced WMH; b) highly correlated (r2 > 0.9) and a steady increase of WMH volumes over time; and c) significant associations of periventricular (t = 22.591, p < 0.001) and deep (t = 14.523, p < 0.001) WMH volumes generated by UBO Detector with Fazekas rating scores. With parallel computing enabled in UBO Detector, the processing can take advantage of multi-core CPU's that are commonly available on workstations. In conclusion, UBO Detector is a reliable, efficient and fully automated WMH segmentation pipeline. PMID- 29578030 TI - Practices and pitfalls in inferring neural representations. AB - A key challenge for cognitive neuroscience is deciphering the representational schemes of the brain. Stimulus-feature-based encoding models are becoming increasingly popular for inferring the dimensions of neural representational spaces from stimulus-feature spaces. We argue that such inferences are not always valid because successful prediction can occur even if the two representational spaces use different, but correlated, representational schemes. We support this claim with three simulations in which we achieved high prediction accuracy despite systematic differences in the geometries and dimensions of the underlying representations. Detailed analysis of the encoding models' predictions showed systematic deviations from ground-truth, indicating that high prediction accuracy is insufficient for making representational inferences. This fallacy applies to the prediction of actual neural patterns from stimulus-feature spaces and we urge caution in inferring the nature of the neural code from such methods. We discuss ways to overcome these inferential limitations, including model comparison, absolute model performance, visualization techniques and attentional modulation. PMID- 29578031 TI - The UNC/UMN Baby Connectome Project (BCP): An overview of the study design and protocol development. AB - The human brain undergoes extensive and dynamic growth during the first years of life. The UNC/UMN Baby Connectome Project (BCP), one of the Lifespan Connectome Projects funded by NIH, is an ongoing study jointly conducted by investigators at the University of North Carolina at Chapel Hill and the University of Minnesota. The primary objective of the BCP is to characterize brain and behavioral development in typically developing infants across the first 5 years of life. The ultimate goals are to chart emerging patterns of structural and functional connectivity during this period, map brain-behavior associations, and establish a foundation from which to further explore trajectories of health and disease. To accomplish these goals, we are combining state of the art MRI acquisition and analysis techniques, including high-resolution structural MRI (T1-and T2-weighted images), diffusion imaging (dMRI), and resting state functional connectivity MRI (rfMRI). While the overall design of the BCP largely is built on the protocol developed by the Lifespan Human Connectome Project (HCP), given the unique age range of the BCP cohort, additional optimization of imaging parameters and consideration of an age appropriate battery of behavioral assessments were needed. Here we provide the overall study protocol, including approaches for subject recruitment, strategies for imaging typically developing children 0-5 years of age without sedation, imaging protocol and optimization, a description of the battery of behavioral assessments, and QA/QC procedures. Combining HCP inspired neuroimaging data with well-established behavioral assessments during this time period will yield an invaluable resource for the scientific community. PMID- 29578032 TI - CaV3.1 isoform of T-type calcium channels supports excitability of rat and mouse ventral tegmental area neurons. AB - Recent data have implicated voltage-gated calcium channels in the regulation of the excitability of neurons within the mesolimbic reward system. While the attention of most research has centered on high voltage L-type calcium channel activity, the presence and role of the low voltage-gated T-type calcium channel (T-channels) has not been well explored. Hence, we investigated T-channel properties in the neurons of the ventral tegmental area (VTA) utilizing wild-type (WT) rats and mice, CaV3.1 knock-out (KO) mice, and TH-eGFP knock-in (KI) rats in acute horizontal brain slices of adolescent animals. In voltage-clamp experiments, we first assessed T-channel activity in WT rats with characteristic properties of voltage-dependent activation and inactivation, as well as characteristic crisscrossing patterns of macroscopic current kinetics. T-current kinetics were similar in WT mice and WT rats but T-currents were abolished in CaV3.1 KO mice. In ensuing current-clamp experiments, we observed the presence of hyperpolarization-induced rebound burst firing in a subset of neurons in WT rats, as well as dopaminergic and non-dopaminergic neurons in TH-eGFP KI rats. Following the application of a pan-selective T-channel blocker TTA-P2, rebound bursting was significantly inhibited in all tested cells. In a behavioral assessment, the acute locomotor increase induced by a MK-801 (Dizocilpine) injection in WT mice was abolished in CaV3.1 KO mice, suggesting a tangible role for 3.1 T-type channels in drug response. We conclude that pharmacological targeting of CaV3.1 isoform of T-channels may be a novel approach for the treatment of disorders of mesolimbic reward system. PMID- 29578033 TI - Propranolol produces short-term facilitation of extinction in a rabbit model of post-traumatic stress disorder. AB - Post-traumatic stress disorder (PTSD) is a learning-based anxiety disorder with significant public health challenges due to difficulties in treating the complex, multiple symptomology. We have developed an animal model of PTSD, based on Pavlovian eyeblink conditioning in rabbits, that addresses two key features: conditioned responses (CRs) to cues associated with an aversive event and a form of conditioned hyperarousal referred to as conditioning-specific reflex modification (CRM). We have found previously that unpaired extinction is ideal for reducing both CRs and CRM simultaneously and shows sensitivity to systemic serotonergic and glutamatergic manipulations. The following study aimed to extend our work to examine the role of the noradrenergic system, dysregulation of which is strongly implicated as part of the neurobiology of PTSD and which may also play a role in the balance shift from fear reconsolidation to extinction during treatment. The goal of the following two studies was to examine whether the beta adrenergic receptor antagonist propranolol combined with either a full or brief course of unpaired extinction treatment could enhance extinction of CRs and/or CRM. Results showed a within-session facilitation of propranolol on extinction of CRs, particularly during the first extinction session, and a short-term enhancement of extinction of CRM when extinction treatment was brief. However, neither benefit translated to long-term extinction retention for the majority of subjects. Findings suggest that propranolol may provide the most therapeutic benefit in situations of high arousal early in treatment, which may be more important for future patient compliance rather than long-term treatment outcomes. PMID- 29578034 TI - The reduction in glutamate release is predictive of cognitive and emotional alterations that are corrected by the positive modulator of AMPA receptors S 47445 in perinatal stressed rats. AB - S 47445 is a positive modulator of glutamate AMPA-type receptors, possessing neurotrophic and enhancing synaptic plasticity effects as well as pro-cognitive and anti-stress properties. Here, the drug was assessed in the perinatal stress (PRS) rat model, known to have a high predictive validity with monoaminergic antidepressants. The effects of a chronic treatment (i.p.) with S 47445 were investigated on risk-taking, motivational and cognitive behavior. S 47445 (1 and 10 mg/kg) increased the exploration of the elevated-plus maze and light/dark box as well as the time spent grooming in the splash test, and improved social memory in PRS rats. Also, the effects of S 47445 were examined on the synaptic neurotransmission. The reduced depolarization-evoked glutamate release induced by PRS was corrected with S 47445 (10 mg/kg). Remarkably, the reduction in glutamate release induced by PRS and corrected by S 47445 chronic treatment was correlated with all the behavioral changes. S 47445 at 10 mg/kg also normalized the lower levels of synaptic vesicle-associated proteins in ventral hippocampus in PRS rats. Finally, S 47445 reversed the decrease of mGlu5 receptors, GR and OXTR induced by PRS. Collectively, in an animal model of stress-related disorders, S 47445 corrected the imbalance between excitatory and inhibitory neurotransmission by regulating glutamate-evoked release that is predictive of PRS behavioral alterations, and also normalized the reduction of trafficking of synaptic vesicles induced by PRS. These results support the interest of glutamatergic based therapeutic strategies to alleviate stress-related disorders. PMID- 29578035 TI - Ras inhibitor S-trans, trans-farnesylthiosalicylic acid enhances spatial memory and hippocampal long-term potentiation via up-regulation of NMDA receptor. AB - Statins by reducing farnesyl-pyrophosphate or farnesyl transferase inhibitors have been demonstrated to enhance spatial memory and long-term potentiation (LTP). The objective of this study was to investigate effects of the synthetic Ras inhibitor S-trans, trans-farnesylthiosalicylic acid (FTS) on spatial cognitive function in adult mice, synaptic plasticity in hippocampal CA1 regions, and NMDA receptor (NMDAr) activity of pyramidal cells. Here, we show that administering FTS (5 mg/kg, i.p.) enhanced spatial cognitive performance, as assessed via Morris water maze and Y-maze tests. Treating hippocampal slices with FTS (5 MUM) for 2 h enhanced selectively NMDAr-dependent LTP without changing the synaptic properties. In comparison with the controls, the FTS-treated slices showed increases in the amplitude of NMDA-evoked currents (INMDA) and the phosphorylation of NMDAr GluN2A/GluN2B subunits and Src. The Src inhibitor PP2 blocked the enhancing effects of FTS on the activity and phosphorylation of NMDAr. In FTS-treated slices, basal levels of CaMKII, ERK2 and CREB phosphorylation did not differ significantly from those of controls; however, high-frequency stimulation-induced increases in CaMKII, ERK2 and CREB phosphorylation were more significant than in the controls, which were sensitive to PP2 and NMDAr antagonist MK801. Furthermore, the phosphorylation of AMPA receptor GluR1 during LTP was higher in FTS-treated slices compared with the control, which depended on Src and ERK1/2 signaling. The results indicate that the Ras inhibition by FTS can enhance NMDAr-dependent LTP by increasing Src activity to promote NMDAr GluN2A/GluN2B phosphorylation, which then leads to spatial memory potentiation. PMID- 29578036 TI - mGlu4 allosteric modulation for treating Parkinson's disease. AB - 2017 is the 200th anniversary of the first published description of Parkinson's disease (PD). Fifty years ago, the clinical benefit of levodopa was first documented, representing the most important advance in the treatment of PD so far. Among the novel targets identified in the last decade, positive allosteric modulators (PAM) of mGlu4 receptors show great promise, with the potential to change the paradigm of the PD treatment approach. mGlu4 PAMs have shown consistent efficacy in various preclinical models of PD, and entered clinical trials for the first time in 2017. This review synthesizes the rationale for mGlu4 PAM development for PD and progress to date, reporting the key achievements from preclinical studies to the first-in-class compound assessment in man. PMID- 29578038 TI - An ensemble learning system for a 4-way classification of Alzheimer's disease and mild cognitive impairment. AB - Discriminating Alzheimer's disease (AD) from its prodromal form, mild cognitive impairment (MCI), is a significant clinical problem that may facilitate early diagnosis and intervention, in which a more challenging issue is to classify MCI subtypes, i.e., those who eventually convert to AD (cMCI) versus those who do not (MCI). To solve this difficult 4-way classification problem (AD, MCI, cMCI and healthy controls), a competition was hosted by Kaggle to invite the scientific community to apply their machine learning approaches on pre-processed sets of T1 weighted magnetic resonance images (MRI) data and the demographic information from the international Alzheimer's disease neuroimaging initiative (ADNI) database. This paper summarizes our competition results. We first proposed a hierarchical process by turning the 4-way classification into five binary classification problems. A new feature selection technology based on relative importance was also proposed, aiming to identify a more informative and concise subset from 426 sMRI morphometric and 3 demographic features, to ensure each binary classifier to achieve its highest accuracy. As a result, about 2% of the original features were selected to build a new feature space, which can achieve the final four-way classification with a 54.38% accuracy on testing data through hierarchical grouping, higher than several alternative methods in comparison. More importantly, the selected discriminative features such as hippocampal volume, parahippocampal surface area, and medial orbitofrontal thickness, etc. as well as the MMSE score, are reasonable and consistent with those reported in AD/MCI deficits. In summary, the proposed method provides a new framework for multi-way classification using hierarchical grouping and precise feature selection. PMID- 29578037 TI - Cocaine evokes a profile of oxidative stress and impacts innate antiviral response pathways in astrocytes. AB - HIV-1 and Zika virus (ZIKV) represent RNA viruses with neurotropic characteristics. Infected individuals suffer neurocognitive disorders aggravated by environmental toxins, including drugs of abuse such as cocaine, exacerbating HIV-associated neurocognitive disorders through a combination of astrogliosis, oxidative stress and innate immune signaling; however, little is known about how cocaine impacts the progression of ZIKV neural perturbations. Impaired innate immune signaling is characterized by weakened antiviral activation of interferon signaling and alterations in inflammatory signaling, factors contributing to cognitive sequela associated with cocaine in HIV-1/ZIKV infection. We employed cellular/molecular biology techniques to test if cocaine suppresses the efficacy of astrocytes to initiate a Type 1 interferon response to HIV-1/ZIKV, in vitro. We found cocaine activated antiviral signaling pathways and type I interferon in the absence of inflammation. Cocaine pre-exposure suppressed antiviral responses to HIV-1/ZIKV, triggering antiviral signaling and phosphorylation of interferon regulatory transcription factor 3 to stimulate type I interferon gene transcription. Our data indicate that oxidative stress is a major driver of cocaine-mediated astrocyte antiviral immune responses. Although astrocyte antiviral signaling is activated following detection of foreign pathogenic material, oxidative stress and increased cytosolic double-stranded DNA (dsDNA) can drive antiviral signaling via stimulation of pattern recognition receptors. Pretreatment with the glial modulators propentofylline (PPF) or pioglitazone (PIO) reversed cocaine-mediated attenuation of astrocyte responses to HIV-1/ZIKV. Both PPF/PIO protected against cocaine-mediated generation of reactive oxygen species (ROS), increased dsDNA, antiviral signaling pathways and increased type I interferon, indicating that cocaine induces astrocyte type I interferon signaling in the absence of virus and oxidative stress is a major driver of cocaine mediated astrocyte antiviral immunity. Lastly, PPF and PIO have therapeutic potential to ameliorate cocaine-mediated dysregulation of astrocyte antiviral immunity possibly via a myriad of protective actions including decreases in reactive phenotype and damaging immune factors. PMID- 29578039 TI - In vivo assessment of the human cerebral microcirculation and its glycocalyx: A technical report. AB - INTRODUCTION: The cerebral microcirculation and its glycocalyx, a matrix coating the luminal endothelium, are key regulators of capillary permeability and cerebral blood flow. Microvascular abnormalities are described in several neurological disorders. However, assessment of the cerebral microcirculation and glycocalyx has mainly been performed ex vivo. NEW METHOD: Here, the technical feasibility of in vivo assessment of the human cerebral microcirculation and its glycocalyx using sidestream dark field (SDF) imaging is discussed. Intraoperative assessment requires the application of a sterile drape covering the camera (slipcover). First, sublingual measurements with and without slipcover were performed in a healthy control to assess the impact of this slipcover. Subsequently, using SDF imaging, the sublingual (reference), cortical, and hippocampal microcirculation and glycocalyx were evaluated in patients who underwent resective brain surgery as treatment for drug-resistant temporal lobe epilepsy. Finally, vessel density, and the perfused boundary region (PBR), a validated gauge of glycocalyx health, were calculated using GlycoCheck(c) software. RESULTS: The addition of a slipcover affects vessel density and PBR values in a control subject. The cerebral measurements in five patients were more difficult to obtain than the sublingual ones. This was probably at least partly due to the introduction of a sterile slipcover. Results on vessel density and PBR showed similar patterns at all three measurement sites. COMPARISON WITH EXISTING METHODS: This is the first report on in vivo assessment of the human cerebrovascular glycocalyx. Assessment of the glycocalyx is an additional application of in vivo imaging of the cerebral microcirculation using SDF technique. This method enables functional analysis of the microcirculation and glycocalyx, however the addition of a sterile slipcover affects the measurements. CONCLUSIONS: SDF imaging is a safe, quick, and straightforward technique to evaluate the functional cerebral microcirculation and glycocalyx. Because of their eminent role in cerebral homeostasis, this method may significantly add to research on the role of vascular pathophysiology underling various neurological disorders. PMID- 29578040 TI - Evaluation of Vasectomy Trends in the United States. AB - OBJECTIVE: To use the Truven Health MarketScan database to better approximate the annual rate of vasectomies performed in the US population, to determine changes over time, regional differences, providers performing this, and to know if there is any monthly variation in vasectomy rates. MATERIALS AND METHODS: Claims data were evaluated from 2007 to 2015 to determine the annual prevalence of vasectomy by patient age and region in the United States. The cohort included men aged 18 64 years with at least 1 claim in any given year in Truven Health MarketScan. Provider type and place of service were evaluated in 2014 and 2015. Monthly evaluation of vasectomy prevalence compared with total claims was performed. RESULTS: The prevalence of vasectomies decreased from 2007 to 2015, across all age groups and in all locations of the country (P <.001). Using these data and the most recent US census data, an estimated 527,476 vasectomies were performed in the United States in 2015. The North Central and West regions (0.64% and 0.60%, respectively) had the highest annual prevalence of vasectomies. The month of March and the end of the year had the highest proportion of vasectomies performed. In both 2014 and 2015, a urologist in the office setting performed 82% of vasectomies. CONCLUSION: An estimated 527,476 vasectomies were performed in the United States in 2015. From 2007 to 2015 there was a decrease in the proportion of vasectomies performed in all age groups and in all locations of the country. The end of the year and the month of March are when the most vasectomies are performed. PMID- 29578041 TI - Intraoperative Conversion From Partial to Radical Nephrectomy: Incidence, Predictive Factors, and Outcomes. AB - OBJECTIVE: To evaluate preoperative and intraoperative predictors of conversion to radical nephrectomy (RN) in a cohort of patients undergoing a planned partial nephrectomy (PN) for renal cell carcinoma (RCC). METHODS: A single-center, retrospective review was conducted using our PN database that includes patients who were scheduled to undergo PN (regardless of the approach) but were converted to RN between August 1990 and December 2016. Reasons for conversion were collected from the operative report. Patient demographics and perioperative variables were compared with the successful PN group. Univariate and multivariate logistic regression analyses were conducted to assess predictors of conversion. RESULTS: A total of 1857 patients were scheduled to undergo PN. Of these patients, 90 (5%) were converted to RN. The multivariate model showed that larger tumor size (odds ratio [OR] = 1.20, P = .040), higher RENAL nephrometry score (OR = 1.41, P = .001), hilar tumor or renal sinus invasion (OR = 2.80, P = .004), laparoscopic PN (OR = 7.34, P <.001), intraoperative bleeding (OR = 19.62, P <.001), positive surgical margin (OR = 31.85, P <.001), and advanced pathologic tumor-stage (T3 or T4) (OR = 7.29, P <.001) were associated with increased odds of intraoperative conversion to RN. CONCLUSION: The rate of conversion to RN was low in patients who were scheduled to undergo PN in this series. Larger tumor size with increasing complexity, hilar tumor location or renal sinus invasion, locally advanced tumors, laparoscopic PN but not robotic PN, bleeding complication, and positive surgical margin were associated with intraoperative conversion from scheduled PN to RN. PMID- 29578042 TI - Volume and Shape Assessment of Renal Radiofrequency Ablation Lesion. AB - OBJECTIVE: To evaluate the microscopic characteristics and quantify the volume of a radiofrequency ablation (RFA) lesion. METHODS: Ten male pigs were submitted to laparoscopic RFA. An RFA needle was introduced in the lower pole of the left kidney to create a lesion expected to be a sphere of 2.0 cm diameter. The animals were followed up for 21 days. Kidneys were weighed and the volume was assessed using Scherle's method. Cavalieri's principle was used to assess the RFA volume, and sphericity was calculated to assess RFA lesion. One sample t test was used to compare RFA volume with the volume of a sphere of 2.0 cm diameter, and sphericity to hypothetical values of a sphere and an icosahedron. Fragments of RFA region were histologically evaluated. RESULTS: Three animals developed postoperative complications and were excluded from the analyses. There was no difference in the mean weight and volume between right and left kidneys following RFA. The mean total volume of RFA injury was 3.44 cm3. There was no difference in the RFA volume in comparison with hypothetical volumes of a sphere and an icosahedron of 2.0 cm diameter. Sphericity of the RFA injury was not similar with a sphere; however, it was similar to an icosahedron. Histology revealed areas of coagulation necrosis, fibrosis, and inflammatory mononuclear infiltration. Areas with normal tissue were also observed. CONCLUSION: The volume of injury caused by RFA was as expected and its shape was comparable with an icosahedron. Microscopic evaluation revealed areas of normal-appearing tissue. PMID- 29578043 TI - No Appendix is Too Short-Simultaneous Mitrofanoff Catheterizable Vesicostomy and Malone Antegrade Continence Enema (MACE) for Children with Spina Bifida. AB - OBJECTIVE: To present the results of simultaneous creation of both Mitrofanoff stoma and Malone antegrade continence stoma (MACE) using simple division of the appendix and a cecal extension method. MATERIALS AND METHODS: Between June 2011 and November 2016, simultaneous Mitrofanoff and MACE was performed in 16 children (12 children-simple division of the appendix, 4 children-appendicovesicostomy and cecal extension of the appendix). Extension of the appendix was achieved by tubularization of the excised cecal flap next to the short appendicular stump. The new extended channel was then wrapped by cecal wall. RESULTS: Follow-up was 40 months (10-74 months). Currently, in all children, both stomas are easily catheterizable. Obstruction of MACE occurred in 5 children (4 with split appendix, 1 with extended appendix); Mitrofanoff stomal stenosis occurred in 1 child. Endoscopic revision and prolonged catheterization of stenotic stomas were effective in all cases. Wound infection and dehiscence was noted in 2 children (both with split appendix). Drainage and intravenous antibiotics were effective. All Mitrofanoffs are continent. In 4 children there is incident minor leakage of the MACE (3 with split appendix and in 1 with extended appendix). CONCLUSION: The split appendix procedure is feasible. Cecal extension of the appendix seems to be a good option when the appendix is too short for a simple split procedure. PMID- 29578044 TI - Systemic and local adipose tissue in knee osteoarthritis. AB - Knee osteoarthritis (OA) is the most common joint disease. Body adipose tissue has been shown to be related to the development and progression of knee OA. Among systemic adipose tissues, subcutaneous adipose tissue is significantly and negatively associated with muscle mass and forces, and could be related to the presence and progression of knee OA. Visceral adipose tissue is associated with increased cartilage loss and production of pro-inflammatory cytokines. Intra muscular adipose tissue is associated with knee osteoarthritic changes, but it remains controversial if inter-muscular adipose tissue has a role to play in the pathogenesis for knee OA. Knee local adipose tissue such as infrapatellar fat pad (IPFP) can interact with neighbouring tissues, and may have a biphasic effect in knee OA. The underlying mechanisms for the roles of the systemic and local fat in knee OA could be related to biomechanical, metabolic, inflammatory factors and fat fibrosis, which may have a separated or combined effect on OA. Tissue engineering from systemic or local adipose tissue is a new research direction, and adipose tissue-derived stem cells from systemic or local adipose tissue may be beneficial for OA cartilage repair. Research on systemic and local adipose tissue would provide novel approaches for prevention and treatment of knee OA, but further studies are required to explore the roles of different adipose tissues in knee OA and the effects of stem cells derived from different adipose tissues on knee OA. PMID- 29578045 TI - Mutations in osteoprotegerin account for the CCAL1 locus in calcium pyrophosphate deposition disease. AB - OBJECTIVE: Mutations on chromosomes 5p (CCAL2) and 8q (CCAL1) have been linked to familial forms of calcium pyrophosphate deposition disease (CPDD). Mutations in the ANKH gene account for CCAL2, but the identity of CCAL1 has been elusive. Recently, a single Dutch kindred with a mutation in the Tumor Necrosis Factor Receptor Super Family member 11B (TNFRSF11B) gene coding for osteoprotegerin (OPG) was described as a gain-of-function mutation. Affected family members had premature generalized osteoarthritis (PGOA) and CPDD. As the TNFRSF11B gene is on 8q, we sought additional evidence that TNFRSF11B was CCAL1, and investigated potential disease mechanisms. DESIGN: DNA from two novel PGOA/CPDD families was screened for sequence variants in the TNFRSF11B gene. Mutations were verified by genotype analysis of affected and unaffected family members. We also investigated effects of normal and mutant OPG on regulators of CPP crystal formation in porcine cartilage. RESULTS: The identical TNFRSF11B mutation described in the Dutch family was present in two novel PGOA/CPDD families. ANKH was normal in affected patient fibroblasts. Exogenous OPG did not alter ANKH mRNA or protein levels, affect translocation of ANKH to the membrane, nor increase [pyrophosphate (PPi)] or other key regulators of CPDD. CONCLUSION: We have firmly established the identity of CCAL1 as TNFRSF11B (OPG). Our findings suggest that this mutation produces disease in an ANKH-independent manner via novel mechanisms not primarily targeting cartilage. This work rationalizes further investigation of OPG pathway components as potential druggable targets for CPDD.

AB - The ability to manipulate the Anopheles gambiae genome and alter gene expression effectively and reproducibly is a prerequisite for functional genetic analysis and for the development of novel control strategies in this important disease vector. However, in vivo transgenic analysis in mosquitoes is limited by the lack of promoters active ubiquitously. To address this, we used the GAL4/UAS system to investigate the promoter of the An. gambiae Polyubiquitin-c (PUBc) gene and demonstrated its ability to drive expression in mosquito cell culture before incorporation into An. gambiae transgenic driver lines. To generate such lines, piggyBac-mediated insertion was used to identify genomic regions able to sustain widespread expression and to create phiC31 docking lines at these permissive sites. Patterns of expression induced by PUBc-GAL4 drivers carrying single intergenic insertions were assessed by crossing with a novel responder UAS mCD8:mCherry line that was created by phiC31-mediated integration. Amongst the drivers created at single, unique chromosomal integration loci, two were isolated that induced differential expression levels in a similar multiple-tissue spatial pattern throughout the mosquito life cycle. This work expands the tools available for An. gambiae functional analysis by providing a novel promoter for investigating phenotypes resulting from widespread multi-tissue expression, as well as identifying and tagging genomic sites that sustain broad transcriptional activity. PMID- 29578048 TI - De novo transcriptome analysis of immune response on cobia (Rachycentron canadum) infected with Photobacterium damselae subsp. piscicida revealed inhibition of complement components and involvement of MyD88-independent pathway. AB - Cobia, Rachycentron canadum, one of the most important aquatic species in Taiwan, has suffered heavy losses from Photobacterium damselae subsp. piscicida, which is the causal agent of photobacteriosis. In this study, the transcriptomic profiles of livers and spleens from Pdp-infected and non-infected cobia were obtained for the first time by Illumina-based paired-end sequencing method with a focus on immune-related genes. In total, 164,882 high quality unigenes were obtained in four libraries. Following Pdp infection, 7302 differentially expressed unigenes from liver and 8600 differentially expressed unigenes from spleen were identified. Twenty-seven of the differently expressed genes were further validated by RT-qPCR (average correlation coefficient 0.839, p-value <0.01). Results indicated a negative regulation of complement components and increased expression of genes involved in MyD88-independent pathway. Moreover, a remarkable finding was the increased expression of IL-10, implying an inadequacy of immune responses. This study not only characterized several putative immune pathways, but also provided a better understanding of the molecular responses to photobacteriosis in cobia. PMID- 29578047 TI - Characterization of a Drosophila glutathione transferase involved in isothiocyanate detoxification. AB - Glutathione transferases (GSTs) are ubiquitous key enzymes that catalyse the conjugation of glutathione to xenobiotic compounds in the detoxification process. GSTs have been proposed to play a dual role in the signal termination of insect chemodetection by modifying odorant and tasting molecules and by protecting the chemosensory system. Among the 40 GSTs identified in Drosophila melanogaster, the Delta and Epsilon groups are insect-specific. GSTs Delta and Epsilon may have evolved to serve in detoxification, and have been associated with insecticide resistance. Here, we report the heterologous expression and purification of the D. melanogaster GST Delta 2 (GSTD2). We investigated the capacity of GSTD2 to bind tasting molecules. Among them, we found that isothiocyanates (ITC), insecticidal compounds naturally present in cruciferous plant and perceived as bitter, are good substrates for GSTD2. The X-ray structure of GSTD2 was solved, showing the absence of the classical Ser catalytic residue, conserved in the Delta and Epsilon GSTs. Using molecular dynamics, the interaction of ITC with the GSTD2 three-dimensional structure is analysed and discussed. These findings allow us to consider a biological role for GSTD2 in chemoperception, considering GSTD2 expression in the chemosensory organs and the potential consequences of insect exposure to ITC. PMID- 29578049 TI - The acute stresses role of the atypical 2-cys peroxiredoxin PmPrx5 in black tiger shrimp (Penaeus monodon) from biological immunity and environmental toxicity stress. AB - As a unique atypical 2-Cys Peroxiredoxin (Prx) of the Prx-like superfamily, Peroxiredoxin5 (Prx5) possesses special properties, such as its enzymatic mechanism, wide subcellular distribution and high affinity for peroxides and peroxynitrite. Prx5 plays a crucial role in oxidative stress, immune responses, cell apoptosis, proliferation, differentiation, intracellular signaling, the modulation of gene expression, ecdysis, etc. In this paper, we obtained a full length Prx5 cDNA sequence (designated PmPrx5) from black tiger shrimp (P. monodon). The full-length PmPrx5 cDNA sequence was 1686 bp containing a 5' untranslated region (UTR) of 76 bp with two nucleotide sequences (AAA), a 3' UTR of 1040 bp with a poly (A) tail and two canonical polyadenylation signal sequences (AATAAA), and an open reading frame of 570 bp encoding 189 amino acid residues with a predicted molecular mass of 20 kDa and a theoretical isoelectric point of 6.29. Phylogenetic trees and multiple sequence alignment showed that the PmPrx5 had strong homology with Prx5 proteins from other species, such as similarity with Palaemon carinicauda (69%) and Macrobrachium rosenbergii (69%), containing the highly conserved functional domain. PmPrx5 mRNA was ubiquitously detected in all tested tissues. After P. monodon was exposed to pathogenic bacteria, osmotic pressure, acidity and alkalinity and the heavy metal, the mRNA expression of PmPrx5 in the gills and hepatopancreas was significantly enhanced (P < 0.01) because of the immune response and declined with heavy metal copper and cadmium challenges as time progressed. The recombinant PmPrx5 protein purified in E. coli (DE3) was further confirmed to exhibit antioxidant activity and antibacterial properties to a certain extent using a bacterial growth inhibition test in both liquid and solid cultures in vitro. E. coli transformed with pRSET-PmPrx5 were dramatically protected in response to metal toxicity stress. Thus, PmPrx5 may be developed as a potential therapeutic drug against pathogenic bacteria and as a biomarker for pollutant levels. This work offers useful clues to further explore the functional mechanism of Prx5 in marine shrimp immunity. PMID- 29578050 TI - Different roles of crayfish hemocytes in the uptake of foreign particles. AB - Crustacean hemocytes are known to remove invading pathogens by phagocytosis. In this study, we investigated how the semigranular cells (SGCs) and granular cells (GCs) of crayfish Cherax quadricarinatus participated in this process. By injecting the animals with excessive amounts of fluorescent microspheres (FMs), we showed that only a small portion of the circulating hemocytes were phagocytic cells, and they took up FMs in a size-dependent manner. The 0.2 MUm FMs were internalized almost entirely by SGCs, while GCs and SGCs both contributed to the uptake of 2 MUm FMs. Further analysis of the hemocytes from the animals injected with a mixture of FMs suggested that there were a subpopulation of SGCs specifically ingesting 0.2 MUm FMs. The size-dependent manner was also applied to biological particles. Escherichia coli was internalized by both SGCs and GCs, whereas white spot syndrome virus (WSSV) was mostly ingested by SGCs. However, the bacterial cells were rapidly taken and cleared from the circulation by the hemocytes, while the WSSV virions were gradually internalized and remained in the cells for a relatively longer period of time. These findings provide basic information of the phagocytic hemocytes of crayfish and how they respond to different foreign particles. PMID- 29578051 TI - Expression patterns of regulatory RNAs, including lncRNAs and tRNAs, during postnatal growth of normal and dystrophic (mdx) mouse muscles, and their response to taurine treatment. AB - Post-natal skeletal muscle growth in mice is very rapid and involves complex changes in many cells types over the first 6 weeks of life. The acute onset of dystropathology also occurs around 3 weeks of age in the mdx mouse model of the human disease Duchenne Muscular Dystrophy (DMD). This study investigated (i) alterations in expression patterns of regulatory non-coding RNAs (ncRNAs) in vivo, including miRNAs, lncRNAs and tRNAs, during early growth of skeletal muscles in normal control C57Bl/10Scsn (C57) compared with dystrophic mdx mice from 2 to 6 weeks of postnatal age, and revealed inherent differences in vivo for levels of 3 ncRNAs between C57 and mdx muscles before the onset of dystropathology. Since the amino acid taurine has many benefits and reduces disease severity in mdx mice, this study also (ii) determined the impact of taurine treatment on these expression patterns in mdx muscles at the onset of dystropathology (3 weeks) and after several bouts of myonecrosis and regeneration (6 weeks). Taurine treatment of mdx mice only altered ncRNA levels when administered from 18 days to 6 weeks of age, but a deficiency in tRNA levels was rectified earlier in mdx skeletal muscles treated from 14 days to 3 weeks. Myogenesis in tissue culture was also used to (iii) compare ncRNA expression patterns for both strains, and (iv) the response to taurine treatment. These analyses revealed intrinsic differences in ncRNA expression patterns during myogenesis between strains, as well as increased sensitivity of mdx ncRNA levels to taurine treatment. PMID- 29578052 TI - Diverse mechanisms of IRF5 action in inflammatory responses. AB - Interferon regulatory factor 5 (IRF5) is a key signal-dependent transcription factor in myeloid cells. Its expression is induced by granulocyte-macrophage colony stimulating factor and interferon-gamma. IRF5 protein is further activated in response to stimulation, translocating to the nucleus where it mediates inflammatory responses. IRF5 is capable of both the up-regulation of pro inflammatory genes and repressing anti-inflammatory mediators, thus polarising macrophages to a pro-inflammatory phenotype. We discuss IRF5 interactions with a wide range of transcriptional regulators that give rise to its diverse effects at the level of chromatin. PMID- 29578053 TI - Inhibition of testicular steroidogenesis and impaired differentiation of Sertoli cells in peripubertal mice offspring following maternal exposure to BDE-209 during lactation suppress germ cell proliferation. AB - Polybrominated diphenyl ethers (PBDEs) are used for fire prevention purpose. BDE 209, a congener of PBDEs, is thyroid hormones (THs)-disrupting chemical because of its structural similarity with THs. Testis is considered as THs-responsive organ and is more susceptible to chemical agents during peripubertal period. This study, therefore, evaluated the effect and possible mechanism(s) of action of maternal exposure to BDE-209 during lactation on germ cell proliferation, testicular steroidogenesis and on differentiation of Sertoli cells (SCs) in relation to altered THs status in peripubertal mice offspring. Lactating Parkes mice were gavaged with 500 and 700 mg/kg BW of BDE-209 in corn oil from postnatal day (PND) 1 to PND 28 along with 6-propyl-2-thiouracil (PTU)-treated positive controls and vehicle-treated controls. Male pups of lactating dams were sacrificed at PND 42. Maternal exposure to BDE-209 during lactation markedly affected testicular histopathology, germ cell proliferation and steroidogenesis with down-regulated expression of various steroidogenic markers in peripubertal mice offspring. Decreased expressions of maturational markers of SCs with a decline in serum THs levels were also evident in these offspring. Results thus suggest that maternal BDE-209 exposure during lactation impairs germ cell proliferation via inhibition of steroidogenic pathway and differentiation of SCs in peripubertal mice offspring. PMID- 29578054 TI - Silver ions are responsible for memory impairment induced by oral administration of silver nanoparticles. AB - Increasing use of silver nanoparticles (AgNPs) results in increased human exposure. AgNPs are able to cross brain-blood barrier and are a risk factor for the brain. Thus, we hypothesized that AgNPs exposure might affect hippocampal dependent memory, which required cognitive coordination processes. To verify the assumption, in this study we evaluated the effects of orally administered bovine serum albumin (BSA)-coated AgNPs on spatial memory, which engage cognitive coordination processes for on-going stimuli segregation. Rats following 28 days of oral administration with 1 mg/kg (n = 10) or 30 mg/kg (n = 10) BSA-AgNPs or saline, a control groups (n = 10, n = 8), were tested with an active place avoidance task in the Carousel Maze test. The study revealed significant impairment of long- and short-term memory, irrespectively of dose of AgNPs, whereas non-cognitive activity was on a similar level. We found significantly higher content of silver in the hippocampus in comparison to the lateral cortex. No silver was found in the cerebellum and the frontal cortex. The nanoSIMS analysis reveal a weak signal of silver in the hippocampus of AgNPs treated animals that should be attributed to the presence of silver in ionic form rather than AgNPs. Our findings indicate that oral exposure to a low dose AgNPs induces detrimental effect on memory and cognitive coordination processes. The presence of silver ions rather than AgNPs in different brain regions, in particular the hippocampus, suggests crucial role of silver ions in AgNPs-induced impairment of the higher brain functions. PMID- 29578055 TI - Serum nitric oxide level correlates with serum brain natriuretic peptide and whole blood viscosity in hemodialysis patients. AB - BACKGROUND: Nitric oxide (NO) is tonically synthesized by the vascular endothelium and known as a marker of vasodilatation and blood flow. As NO has a critical role in hemodynamics, NO may be associated with other hemodynamics related factors including atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP) and whole blood viscosity (WBV). It has been reported that serum NO level increased in patients undergoing hemodialysis. However, there are few reports about the relationship between NO and hemodynamic parameters in hemodialysis patients. OBJECTIVE: We investigated the associations between serum levels of NO and other hemodynamics-related factors such as ANP, BNP and WBV in patients with hemodialysis. METHODS: NO, ANP, and BNP levels before hemodialysis were measured using ELISA method. We measured WBV in pre- and post-dialysis. RESULTS: Mean serum levels of NO, ANP, and BNP were 13.97 +/- 10.34 MUg/mL, 198.85 +/- 61.56 pg/mL, and 1233.32 +/- 280.81 pg/mL, respectively in patients with hemodialysis. The mean WBV values at shear rates of 1, 5, and 300 s-1 for pre-dialyses were 168.5 +/- 62.5, 76.9 +/- 20.6, and 33.3 +/- 3.8 mP, respectively. Serum NO level was positively correlated with WBV at shear rates of 1, 5, and 300 s-1 at pre- and post-hemodialysis. There is a correlation between serum nitrite levels and the change of SBV during hemodialysis. Serum nitrite levels correlated with the serum BNP levels. ANP levels have a negative correlation with pre-dialytic WBV. However, BNP levels did not correlate with WBV during hemodialysis. CONCLUSIONS: WBV is linked to an imbalance in serum vasoactive substances in hemodialysis patients and can cause significant hemodynamic disturbance.

AB - The nitric oxide/soluble guanylyl cyclase (NO-sGC) signaling pathway regulates the cardiovascular, neuronal, and gastrointestinal systems. Impaired sGC signaling can result in disease and system-wide organ failure. This review seeks to examine the redox control of sGC through heme and cysteine regulation while discussing therapeutic drugs that target various conditions. Heme regulation involves mechanisms of insertion of the heme moiety into the sGC protein, the molecules and proteins that control switching between the oxidized (Fe3+) and reduced states (Fe2+), and the activity of heme degradation. Modifications to cysteine residues by S-nitrosation on the alpha1 and beta1 subunits of sGC have been shown to be important in sGC signaling. Moreover, redox balance and localization of sGC is thought to control downstream effects. In response to altered sGC activity due to changes in the redox state, many therapeutic drugs have been developed to target decreased NO-sGC signaling. The importance and relevance of sGC continues to grow as sGC dysregulation leads to numerous disease conditions. PMID- 29578058 TI - The chemical foundations of nitroalkene fatty acid signaling through addition reactions with thiols. AB - Nitroalkene fatty acids can be formed in vivo and administered exogenously. They exert pleiotropic signaling actions with cytoprotective and antiinflammatory effects. The presence of the potent electron withdrawing nitro group confers electrophilicity to the adjacent beta-carbon. Thiols (precisely, thiolates) are strong nucleophiles and can react with nitroalkene fatty acids through reversible Michael addition reactions. In addition, nitroalkene fatty acids can undergo several other processes including metabolic oxidation, reduction, esterification, nitric oxide release and partition into hydrophobic compartments. The signaling actions of nitroalkenes are mainly mediated by reactions with critical thiols in regulatory proteins. Thus, the thio-Michael addition reaction provides a framework for understanding the molecular basis of the biological effects of nitroalkene fatty acids at the crossroads of thiol signaling and electrophilic lipid signaling. In this review, we describe the reactions of nitroalkene fatty acids in biological contexts. We focus on the Michael addition-elimination reaction with thiols and its mechanism, and extrapolate kinetic and thermodynamic considerations to in vivo settings. PMID- 29578057 TI - Inflammatory signaling and metabolic regulation by nitro-fatty acids. AB - The addition of nitrogen dioxide (NO2) to the double bond of unsaturated fatty acids yields an array of electrophilic nitro-fatty acids (NO2-FA) with unique biochemical and signaling properties. During the last decade, NO2-FA have been shown to exert a protective role in various inflammatory and metabolic disorders. NO2-FA exert their biological effects primarily by regulating two central physiological adaptive responses: the canonical inflammatory signaling and metabolic pathways. In this mini-review, we summarize current knowledge on the regulatory role of NO2-FA in the inflammatory and metabolic response via regulation of nuclear factor kappa B (NF-kappaB) and peroxisome proliferator activated receptor gamma (PPARgamma), master regulators of inflammation and metabolism. Moreover, the engagement of novel signaling and metabolic pathways influenced by NO2-FA, beyond NF-kappaB and PPAR signaling, is discussed herein. PMID- 29578059 TI - The effect of the electrophilic fatty acid nitro-oleic acid on TRP channel function in sensory neurons. AB - Nitro-oleic acid (NO2-OA) and related nitroalkenes are electrophilic fatty acid derivatives that are present in normal tissues at nanomolar concentrations and can increase significantly during inflammation. These substances can suppress multiple intracellular signaling pathways contributing to inflammation by reversible Michael addition reactions with nucleophilic residues such as cysteine and histidine leading to post-translational modification of proteins. NO2-OA also can influence inflammation and pain by acting on transient receptor potential (TRP) channels in primary sensory neurons. TRPV1, TRPA1 and TRPC can respond to electrophilic fatty acids because they have ankyrin-like repeats in their N terminus that are rich in cysteine residues that react with electrophiles and other thiol modifying species. NO2-OA acts on TRP channels to initially depolarize and induce firing in sensory neurons followed by desensitization and suppression of firing. In vivo experiments revealed that pretreatment with NO2-OA reduces nociceptive behavior evoked by local administration of a TRPA1 agonist (AITC) to the rat hind paw. These results raise the possibility that NO2-OA might be useful clinically to reduce neurogenic inflammation and certain types of painful sensations by desensitizing TRPA1 expressing nociceptive afferents. PMID- 29578060 TI - Complete genome sequence of Bacillus licheniformis BL-010. AB - The biodegradation of Aflatoxin B1 (AFB1) is an industry of increasing importance. Bacillus licheniformis BL-010 was isolated from the aflatoxin contaminated corn feed storage, and was shown to degrade AFB1 efficiently. Here we present the complete genome sequence of BL-010, the genome comprises 4,287,714 bp in a circular chromosome with a GC content of 46.12% and contains genes encoding AFB1 degrading enzymes. The genome sequence displayed that this strain contains genes involved in production of laccase, aromatic ring-opening dioxygenase which could detoxify AFB1. Complete genome sequence of the strain BL 010 can further provide the genomic basis for the biotechnological application of strain BL-010 as an effective way to degrade AFB1. PMID- 29578061 TI - Mefloquine targets beta-catenin pathway and thus can play a role in the treatment of liver cancer. AB - The current study was designed and performed to investigate the effect of mefloquine on the proliferation and tumor formation potential of liver cancer stem cells. CD133 + HepG2 cells were identified using MACS and showed markedly higher tumor formation potential compared to the parental cells. The secondary tumors formed by CD133 + cells were markedly large in size and more in number compared to the parental cells. Mefloquine treatment of CD133 + HepG2 cells inhibited the proliferation selectively in concentration based manner. The rate of proliferation was inhibited to 82 and 12% in parental and CD133 + sphere forming cells, respectively on treatment with 10 MUM concentration of mefloquine. The number of secondary tumors formed by primary tumors was decreased significantly on treatment with 10 MUM mefloquine concentration. Treatment of the liver cancer stem cells with mefloquine markedly decreased the potential to undergo self-renewal at 10 MUM concentration after 48 h. The results from western blot analysis showed significantly higher expression of cancer stem cell molecules beta-catenin and cyclin D1 in LCSCs. Treatment of the LCSCs with various concentrations of mefloquine reduced the expression levels of beta catenin and cyclin D1. Administration of the CD133 + cell tumor xenografts in the mice led to the formation of large sized tumors in the control group. However, the tumor growth was inhibited significantly in the mice on treatment with 10 mg/kg doses of mefloquine after day 21. The tumor weight was significantly lower in the animals of mefloquine treatment group compared to the control group. Thus, mefloquine treatment inhibits self-renewal and proliferation potential of cells through targeting beta-catenin pathway. PMID- 29578062 TI - Characterization of essential oil from Ocimum gratissimum leaves: Antibacterial and mode of action against selected gastroenteritis pathogens. AB - Essential oil of fresh leaves of Ocimum gratissimum (OGEO) was water-steam distilled and analyzed by GC-MS. Thirty-seven compounds were identified, with eugenol (55.6%) as the major component followed by cis-ocimene (13.9%), gamma muurolene (11.6%), (Z,E)-alpha-farnesene (5.6%), alpha-trans-bergamotene (4.1%), and beta-caryophyllene (2.7%). Antimicrobial activity of OGEO was tested against four gastroenteritis pathogens (Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, and Shigella flexneri). OGEO exhibited antibacterial effect, with MICs of 1-2 mg ml-1, against the tested species. OGEO also displayed rapid killing effect within 5 s at four times of MIC against both E. coli and S. Typhimurium. Various assays were performed to investigate the mode of action of the oil. OGEO increased the permeability of microbial cell membrane as evidenced by LIVE/DEAD BacLight assay. Analyses of the release of absorbing materials at 260 nm, protein leakage, SDS-PAGE, and SEM strongly suggested the disruptive action of the oil on the cytoplasmic membrane of the tested microorganisms. Results revealed that the antibacterial property of OGEO could be due to membrane disruption. PMID- 29578063 TI - Diversity of virulence genes in Brucella melitensis and Brucella abortus detected from patients with rheumatoid arthritis. AB - The presence of Brucella melitensis and Brucella abortus genomes were investigated in the synovial fluid (SF) samples from 90 patients with rheumatoid arthritis (RA). DNA extraction and PCR assay were performed for simultaneous identification and discrimination of B. melitensis and B. abortus from the SF using three specific primers. After gel electrophoresis, the PCR products were confirmed by DNA sequencing. The cbg, omp31, manA, virB, and znuA virulence genes typing were performed by multiplex-PCR. Of the 90 samples, 14 were positive for B. melitensis (n = 9; 10%) and B. abortus (n = 5; 5.5%). The virulotyping of positive samples revealed the presence of all five virulence genes in B. melitensis. The virB, cbg, and om31 were detected in all five samples of B. abortus. In addition, zhuA and manA were detected in three (60%) and four (80%) samples, respectively, of the B. abortus-positive samples. Moreover, a total of 94.2% and 89.2% of the 14 positive samples were also found positive for manA and znuA, respectively. Our findings revealed that the Brucella spp. genomes can be detected in the SF of RA patients by the PCR-based method. We thus suggest that physicians should consider the Brucella spp. as indicators of potential RA for the timely diagnosis and treatment of RA. PMID- 29578064 TI - Oscimum sanctum extract inhibits growth of Gram positive and Gram negative bacterial strains. AB - In the present study petroleum ether, chloroform and methanolic extracts of Oscimum sanctum were prepared using soxhlet extractor. The extracts were evaluated for antibacterial activity against one Gram positive (Staphylococcus aureus) and one Gram negative (Escherichia coli) strain. The activity of the extracts was compared with the known antibacterial drugs, Oflaxacin and Penicillin G. Disc diffusion method revealed good antibacterial activity of the chloroform and methanol extracts compared to the petroleum ether extract. Methanolic extract was found to be most active against both Staphylococcus aureus and Escherichia coli bacterial strains. The zone of inhibition of methanolic extract against Staphylococcus aureus and Escherichia coli at 50 mg concentration was 16.0 and 18.0 mm, respectively. Chloroform extract also exhibited good antibacterial activity against Staphylococcus aureus and Escherichia coli bacterial strains. The zone of inhibition of chloroform extract against Staphylococcus aureus and Escherichia coli bacterial strains was 8.0 and 6.0 mm, respectively. The zone of inhibition of the drug Penicillin G against Escherichia coli and Staphylococcus aureus was18.0 and 17.0 mm, respectively. Oflaxacin showed zone of inhibition to be 19.0 and 20.0 against Escherichia coli and Staphylococcus aureus, respectively. The petroleum ether extract exhibited no activity against any of the two tested bacterial strains. These findings suggest that methanolic extract of Oscimum sanctum has anti-bacterial potential and therefore should be investigated for phytochemistry. PMID- 29578065 TI - Biofilm formation by Salmonella Enteritidis and Salmonella Typhimurium isolated from avian sources is partially related with their in vivo pathogenicity. AB - Salmonella Enteritidis and Salmonella Typhimurium are among the most prevalent serotypes isolated from salmonellosis outbreaks and poultry. Salmonella spp. have the capacity to form biofilms on several surfaces, which can favour survival in hostile environments, such as slaughterhouses. Salmonella strains present differences in pathogenicity. However, there is little information regarding the pathogenicity of S. Enteritidis and S. Typhimurium isolated from avian sources and their relationship to biofilm production. The aim of this study was to use a novel pathogenicity index and a biofilm production assay to evaluate their relationships within these serotypes. In addition, we detected the presence of the spiA and agfA genes in these strains. Biofilm formation was investigated at two temperatures (37 degrees C and 28 degrees C) using microtiter plate assay, and the results were compared with the individual pathogenicity index of each strain. PCR was used to detect spiA and agfA, virulence genes associated with biofilm production. S. Enteritidis and S. Typhimurium strains were capable of producing biofilm at 37 degrees C and 28 degrees C. Sixty-two percent and 59.5% of S. Enteritidis and 73.8% and 46.2% of S. Typhimurium produced biofilm at 37 degrees C and 28 degrees C, respectively. Biofilm production at 37 degrees C was significantly higher in both serotypes. Only S. Enteritidis was capable of adhering strongly at both temperatures. Biofilm production was related to pathogenicity index only at 28 degrees C for S. Enteritidis. spiA and agfA were found in almost all strains and were not statistically associated with biofilm production. PMID- 29578066 TI - The most common spoligotype of Mycobacterium bovis isolated in the world and the recommended loci for VNTR typing; A systematic review. AB - Mycobacterium bovis is a neglected zoonotic organism that epidemiological studies are of crucial importance in identifying its source, control it and prevent it from spreading. The aim of this study was to investigate the most common spoligotypes of Mycobacterium bovis circulating around the world and introduce the most and least strong determine powers of loci for VNTR. We have used different databases such as ISC, science direct, Embase (Elsevier), Web of Science, Scopus and Medline via PubMed. Searches were performed by key words including: Mycobacterium bovis, MIRU -VNTR, spoligotyping and discrimination power. Finally, thirty-one articles were selected after filtering out some titles, abstracts and full texts. Spoligotype SB0120 was the most common circulating type on several continents while SB0121 existed in Europe, Africa and America. SB0140 was also detected in Asia, Europe and America. QUB3232 and QUB11b were more appropriate loci among the loci with high discriminatory power. MIRU 10 and MIRU4 were among the loci with poor discriminatory power. Taking the published data into consideration, SB0120 and SB0121 are predominant spoligotypes of M. bovis circulating among animals around the world. Determining the most common spoligotype of M. bovis is the key to find source of infection, control and prevent the disease. PMID- 29578067 TI - Impact of parenteral antimicrobial administration on the structure and diversity of the fecal microbiota of growing pigs. AB - While antimicrobials are cost-effective tools for prevention and treatment of infectious disease, the impact of their use on potentially beneficent mucosal microbial communities of growing pigs has not been widely explored. The objective of this study was to characterize the impact of parenteral antibiotics administration on the composition and diversity of the resident fecal microbiota in growing pigs. Five antimicrobial treatment groups, each consisting of four, eight-week old piglets, were administered one of the antimicrobials; Ceftiofur Crystalline free acid (CCFA), Ceftiofur hydrochloride (CHC), Oxytetracycline (OTC), Procaine Penicillin G (PPG) and Tulathromycin (TUL) at label dose and route. Individual fecal swabs were collected immediately before antimicrobial administration (control = day 0), and again on days 1, 3, 7, and 14 after dosing. Genomic DNA was extracted, and the V1-V3 hypervariable region of 16S rRNA gene was amplified and sequenced using Illumina Miseq-based sequencing. Across all groups, the most abundant phyla were Firmicutes, Bacteroidetes, and Proteobacteria. Linear discriminant analysis and stacked area graphs, showed a pronounced, antimicrobial-dependent shift in the composition of fecal microbiota over time from day 0. By day 14, the fecal microbial compositions of the groups receiving CHC and TUL had returned to a distribution that closely resembled that observed on day 0, but differences were still evident. In contrast, animals that received PPG, OTC and CCFA, showed a tendency towards a balanced homeostatic microbiota structure on day 7, but appeared to deviate away from the day 0 composition by day 14. Based on our results, the observed changes in fecal microbiota showed antimicrobial-specific variation in both duration and extent. Understanding the impact of these important antimicrobial-induced changes will be a critical step in optimizing the use of antimicrobials in health management programs in the swine industry. PMID- 29578068 TI - Generation and evaluation of a recombinant Newcastle disease virus strain R2B with an altered fusion protein cleavage site as a vaccine candidate. AB - Newcastle disease (ND) is a highly contagious and fatal disease of chickens. Newcastle disease virus (NDV) strain R2B is an Indian mesogenic strain used for secondary vaccination in chickens. Mesogenic strains have increased virulence and immunogenicity but may cause disease in vaccinated birds, thus rendering them ineffective for use. In this study, we generated a recombinant NDV by changing the fusion protein cleavage site of mesogenic rNDV-R2B from a polybasic amino acid motif RRQKRF to a dibasic amino acid motif GRQGRL leading to generation of an attenuated virus, rNDV-R2B-FPCS. The modified recombinant virus had similar growth characteristics as rNDV-R2B, but was less virulent in susceptible chickens. Immunization of the recombinant attenuated virus to one week of age SPF chickens generated a protective immune response with a substantial reduction in virus shed after challenge with virulent NDV. The results of the study indicate that the modified rNDV-R2B-FPCS virus can be used for primary immunization in birds without any adverse reactions.

AB - Gene correction is a valuable strategy for treating inherited retinal degenerative diseases, a major cause of irreversible blindness worldwide. Single gene defects cause the majority of these retinal dystrophies. Gene augmentation holds great promise if delivered early in the course of the disease, however, many patients carry mutations in genes too large to be packaged into adeno associated viral vectors and some, when overexpressed via heterologous promoters, induce retinal toxicity. In addition to the aforementioned challenges, some patients have sustained significant photoreceptor cell loss at the time of diagnosis, rendering gene replacement therapy insufficient to treat the disease. These patients will require cell replacement to restore useful vision. Fortunately, the advent of induced pluripotent stem cell and CRISPR-Cas9 gene editing technologies affords researchers and clinicians a powerful means by which to develop strategies to treat patients with inherited retinal dystrophies. In this review we will discuss the current developments in CRISPR-Cas9 gene editing in vivo in animal models and in vitro in patient-derived cells to study and treat inherited retinal degenerative diseases. PMID- 29578071 TI - The phagosome and redox control of antigen processing. AB - In addition to debris clearance and antimicrobial function, versatile organelles known as phagosomes play an essential role in the processing of exogenous antigen in antigen presenting cells. While there has been much attention on human leukocyte antigen haplotypes in the determination of antigenic peptide repertoires, the lumenal biochemistries within phagosomes and endosomes are emerging as equally-important determinants of peptide epitope composition and immunodominance. Recently, the lumenal redox microenvironment within these degradative compartments has been shown to impact two key antigenic processing chemistries: proteolysis by lysosomal cysteine proteases and disulfide reduction of protein antigens. Through manipulation of the balance between oxidative and reductive capacities in the phagosome-principally by modulating NADPH oxidase (NOX2) and gamma-interferon-inducible lysosomal thiol reductase (GILT) activities studies have demonstrated changes to antigen processing patterns leading to modified repertoires of antigenic peptides available for presentation, and subsequently, altered disease progression in T cell-driven autoimmunity. This review focuses on the mechanisms and consequences of redox-mediated phagosomal antigen processing, and the potential downstream implications to tolerance and autoimmunity. PMID- 29578072 TI - A review on ethnomedicinally important pteridophytes of India. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Pteridophytes have been considered an excellent source of medicine since ancient times and remain underexplored in ethnobotanical aspects when compared to other vascular plants. Hence, an attempt has been made to compile medicinally important pteridophytes used by different ethnic minorities and local people in India. MATERIALS AND METHODS: Relevant information on the uses of pteridophytes was extracted from scientific journals (local, regional, and international), books, book chapters, conference proceedings, M.Sc. and Ph.D. dissertations, and other scientific databases. Recent and accepted names of plants were validated using standard nomenclature databases. RESULTS: In total, 283 species of pteridophytes are enumerated in this review which are used to treat 129 ailments. Ethnobotanical records from the states Madhya Pradesh, Tamil Nadu, Assam, Arunachal Pradesh, and Uttarakhand revealed 59% of overall uses of pteridophytes from India. Pteridaceae was recorded with highest number of medicinally important species (57), followed by Polypodiaceae, Dryopteridaceae, Thelypteridaceae, and Aspleniaceae with 36, 27, 22, and 21 species respectively. CONCLUSIONS: The use of medicinal plants in the primary healthcare of humans and livestock has been documented since ancient times, and they offer a useful source of new therapeutics. While pteridophytes have considerable importance in traditional pharmacopoeias, scientific studies on pharmacology of this group are scanty. Hence, studies on the phytochemistry and pharmacology of medicinally important pteridophytes with more citations may reveal active principles that can be further developed into novel therapeutic agents. Records of indigenous medicinal knowledge about pteridophytes need to be given top priority to aid the protection of such knowledge before they vanish from present day traditional healers. PMID- 29578070 TI - An evolving understanding of the S-glutathionylation cycle in pathways of redox regulation. AB - By nature of the reversibility of the addition of glutathione to low pKa cysteine residues, the post-translational modification of S-glutathionylation sanctions a cycle that can create a conduit for cell signaling events linked with cellular exposure to oxidative or nitrosative stress. The modification can also avert proteolysis by protection from over-oxidation of those clusters of target proteins that are substrates. Altered functions are associated with S glutathionylation of proteins within the mitochondria and endoplasmic reticulum compartments, and these impact energy production and protein folding pathways. The existence of human polymorphisms of enzymes involved in the cycle (particularly glutathione S-transferase P) create a scenario for inter-individual variance in response to oxidative stress and a number of human diseases with associated aberrant S-glutathionylation have now been identified. PMID- 29578073 TI - De-Escalation and Discontinuation of Empirical Antibiotic Treatment in a Cohort of Allogeneic Hematopoietic Stem Cell Transplantation Recipients during the Pre Engraftment Period. AB - To investigate rates and outcomes of antibiotic de-escalation during pre engraftment neutropenia in allogeneic hematopoietic stem cell transplantation (HSCT) recipients. 110 consecutive HSCTs performed between January 2013 and March 2014 were analyzed. De-escalation was defined as narrowing the spectrum of antibiotic treatment either within (early) or after 96 hours (late) from starting antibiotics. Discontinuation, considered a form of de-escalation, was defined as stopping antibiotics before engraftment. De-escalation failure was defined as restarting/escalating antibiotics within 96 hours after de-escalation. Predictors of de-escalation were analyzed. Among 102 patients who started antibiotics and were included, 68 (67%) received monotherapy (mainly piperacillin-tazobactam, n = 58), whereas 34 (33%) received combination therapy (mainly meropenem plus glycopeptide, n = 24). Median duration of neutropenia was 17 days. Bloodstream infections (BSIs) were diagnosed in 28 patients (20%). Early de-escalation rate was 25.5% (n = 26) and mostly consisted of reducing the spectrum of beta-lactams (n = 11, 42%). In comparison with theoretical scenario of continuing therapy until engraftment, the median savings in terms of antibiotic days were 10 for meropenem, 8 for piperacillin-tazobactam, and 7 for vancomycin. Failure rate of early de-escalation was 15% (4/26). Late de-escalation rate was 30.4% (n = 31) and failure rate 19% (6/31). The rate of de-escalation any time before engraftment was 55.9% (n = 57), including discontinuation in 33 patients (32%). Death at day 60 after HSCT occurred in 3 patients who never underwent de escalation. Acute myeloid disease and BSIs were independent predictors of early de-escalation. De-escalation, including discontinuation, is feasible and safe in pre-engraftment neutropenia after allogeneic HSCT.

AB - This paper describes a simple, straightforward, and rapid method for producing microspheres from molten polymers by merely printing them in an inkjet-like manner onto a superoleophobic surface (microsphere printing, hence SPHRINT). Similar to 3D printing, a polymer melt is deposited onto a surface; however, in contrast to 2D or 3D printing, the surface is not wetted (i.e. exhibiting high contact angles with liquids, above 150 degrees , due to its low surface energy), resulting in the formation of discrete spherical microspheres. In this study, microspheres were printed using polycaprolactone and poly(lactic-co-glycolic acid) loaded with a model active pharmaceutical ingredient-ibuprofen (IBU). The formation of microspheres was captured by high-speed imaging and was found to involve several physical phenomena characterized by non-dimensional numbers, including the thinning and breakup of highly viscous, weakly elastic filaments, which are first to be described in pure polymer melts. The resulting IBU-loaded microspheres had higher sphericity, reproducible sizes and shapes, and superior drug encapsulation efficiencies with a distinctly high process yield (>95%) as compared to the conservative solvent-based methods used presently. Furthermore, the microspheres showed sustained release profiles. PMID- 29578075 TI - The effects of maternal diabetes and insulin treatment on neurogenesis in the developing hippocampus of male rats. AB - Diabetes in pregnancy is associated with an increasing risk of congenital malformations and central nervous system disorders (CNS) especially hippocampal neuronal circuitry disruption as a discreet region involved in neurogenesis phenomenon. This study aimed to investigate the effect of maternal diabetes and insulin treatment on the expression and distribution pattern of NeuN and DCX as two important markers of neurogenesis paradigm in developing rat hippocampus. All animals were randomly divided into three groups as follows: Control group, Diabetic (STZ-D), Diabetic treated with insulin (STZ-INS). Diabetes was induced in Wistar female rats by Sterptozotocin intraperitoneal injection (single does). Following confirmation of diabetes, animals were mated with non-diabetic males. Four to six units of protamine-Zinc insulin were delivered subcutaneously (SC) in insulin treated group. At the post-natal day 14 (P14), the brain of male offspring's were removed for further study. In fact Immunofluorescence staining and Real time - PCR assays are used for evaluation of neurogenesis phenomenon. Our results showed a significant higher level of hippocampal DCX expression and an increase in the mean number of DCX positive cells in the DG of diabetic group male offspring (P < 0.05). We also found an insignificant up-regulation in the expression of DCX and the mean number of positive cells in the insulin-treated diabetic group neonates as compared to control group (P > 0.05). Nevertheless the results of immunofluorescence staining for NeuN also indicated that the mean number of NeuN+ cells was significantly lower in dentate gyrus of diabetic group male offspring (P < 0.05). Besides, there were significant down- regulation in the hippocampal mRNA expression of NeuN in diabetic pups compare to control (P < 0.05 each). Our results revealed that diabetes during pregnancy has an adverse effect on the hippocampal neurogenesis in rat neonates. Furthermore, the control of glycemia by insulin is sufficient to prevent the alterations in expression of neurogenesis markers.

AB - Surgical treatment of large paraclinoid aneurysms remains technically challenging due to the adjacent bony anatomy and neurovascular structures. Endovascular retrograde suction decompression using a double-lumen balloon catheter facilitates clip ligation of the aneurysm. Video 1 demonstrates a large paraclinoid aneurysm that was treated with endovascular balloon occlusion and retrograde suction decompression in a hybrid operating room. A 49-year-old woman presented with progressively worsening headache. Computed tomography angiography demonstrated a large 16-mm left paraclinoid aneurysm. Neurologic examination showed no deficits. Angiography with compression of the left carotid artery showed the collateral blood flow through the posterior communicating artery. The aneurysm was exposed via the pterional transsylvian approach. A double-lumen balloon guide catheter was placed in the left internal carotid artery. Considering the risk of ischemic complications, the "trapping-evacuation" technique was not used. After balloon inflation, a temporary clip was placed on the posterior communicating artery. Retrograde suction through the guide catheter decreased the intra-aneurysmal pressure. Tandem clipping with fenestrated clips was used to occlude the aneurysm and reconstruct the parent artery. Postoperative angiography confirmed complete obliteration of the aneurysm, and the patient recovered without any neurologic deficits. Endovascular balloon occlusion obviated the need for cervical dissection of the internal carotid artery. Retrograde suction decompression and intraoperative angiography facilitated surgical clipping for large and giant paraclinoid aneurysms. PMID- 29578081 TI - Effective cellular internalization, cell cycle arrest and improved pharmacokinetics of Tamoxifen by cholesterol based lipopolymeric nanoparticles. AB - The present study aims at the development of cholesterol based lipopolymeric nanoparticles for improved entrapment, better cell penetration and improved pharmacokinetics of Tamoxifen (TMX). Self-assembling cholesterol grafted lipopolymer, mPEG-b-(CB-{g-chol}-co-LA) was synthesized from poly(ethyleneglycol) block-2-methyl-2-carboxyl-propylenecarboxylic acid-co-poly (l-lactide) [mPEG-b (CB-{g-COOH}-co-LA)] copolymer followed by carbodiimide coupling for attaching cholesterol. Lipopolymeric nanoparticles were prepared using o/w solvent evaporation technique, which were subsequently characterized to determine its particle size, entrapment efficiency, release pattern and compared with mPEG-PLA nanoparticles. Further, in order to assess the in vitro efficacy, cytotoxicity studies, uptake, apoptosis assay and cell cycle analysis were performed in breast cancer cell lines (MCF-7 and 4T1). Finally, the pharmacokinetic profile of TMX loaded mPEG-b-(CB-{g-chol}-co-LA) lipopolymeric nanoparticles was also performed. TMX loaded lipopolymeric nanoparticles of particle size 151.25 +/- 3.74 (PDI 0.123) and entrapment efficiency of 73.62 +/- 3.08% were formulated. The haemolytic index, protein binding and in vitro drug release of the optimized nanoparticles were found to be comparable to that of the TMX loaded mPEG-PLA nanoparticles. Lipopolymeric nanoparticles demonstrated improved IC50 values in breast cancer cells (22.2 MUM in 4T1; 18.8 MUM in MCF-7) than free TMX (27.6 MUM and 23.5 MUM respectively) and higher uptake efficiency. At IC50 values, TMX loaded lipopolymeric nanoparticles induced apoptosis and cell cycle arrest (G0/G1 phase) to similar extent as that of free drug. Pharmacokinetic studies indicated ~2.5-fold increase in the half-life (t1/2) (p < 0.001) and ~2.7-fold (p < 0.001) increase in the mean residence time (MRT) of TMX following incorporation into lipopolymeric nanoparticles. Thus, mPEG-b-(CB-{g-chol}-co-LA) lipopolymeric nanoparticles offer a more promising approach for delivery of Tamoxifen in breast cancer by improving drug internalization and prolonging the mean residence time of the drug indicating possibility of dose reduction and hence bypassing the adverse effects of TMX therapy. PMID- 29578082 TI - Genetics of human and animal uncultivable treponemal pathogens. AB - Treponema pallidum is an uncultivable bacterium and the causative agent of syphilis (subsp. pallidum [TPA]), human yaws (subsp. pertenue [TPE]), and bejel (subsp. endemicum). Several species of nonhuman primates in Africa are infected by treponemes genetically undistinguishable from known human TPE strains. Besides Treponema pallidum, the equally uncultivable Treponema carateum causes pinta in humans. In lagomorphs, Treponema paraluisleporidarum ecovar Cuniculus and ecovar Lepus are the causative agents of rabbit and hare syphilis, respectively. All uncultivable pathogenic treponemes harbor a relatively small chromosome (1.1334 1.1405 Mbp) and show gene synteny with minimal genetic differences (>98% identity at the DNA level) between subspecies and species. While uncultivable pathogenic treponemes contain a highly conserved core genome, there are a number of highly variable and/or recombinant chromosomal loci. This is also reflected in the occurrence of intrastrain heterogeneity (genetic diversity within an infecting bacterial population). Molecular differences at several different chromosomal loci identified among TPA strains or isolates have been used for molecular typing and the epidemiological characterization of syphilis isolates. This review summarizes genome structure of uncultivable pathogenic treponemes including genetically variable regions. PMID- 29578083 TI - Social geography of Rhinoscleroma and qualitatively and quantitatively abnormal cell-mediated immunity. AB - Rhinoscleroma is a progressive chronic granulomatous disease of the upper respiratory tract that may extend to the tracheobronchial tract. It is common belief that the pathology is determined by Klebsiella Rhinoscleromatis. In the authors' opinion, the infection with Klebsiella Rhinoscleromatis may not represent the only etiopathogenic factor of the disease. Rhinoscleroma is reported in many countries, but has a peculiar social and geographic distribution, in that it assumes an endemic character only in some regions of the Middle East, West Russia, North Africa, Indonesia, Central and South America. In Europe, most of the cases are reported in Poland, Hungary and Romania. In Italy, Rhinoscleroma is almost exclusively located in the southern and island regions. Rhinoscleroma is predominantly reported in rural areas, in the presence of poor socio-economic conditions, which according to many authors would be a co-factor triggering the disease. In this article, the authors review some inconsistencies in etiology, histology and epidemiology of Rhinoscleroma. Based on the overall picture, they propose that intrinsic factors, possibly of genetic origin, may give rise to the disease, and suggest possible lines of research to distinguish between extrinsic and intrinsic factors as determinants for Rhinoscleroma. PMID- 29578084 TI - Risk factors and prediction analysis of cutaneous leishmaniasis due to Leishmania tropica in Southwestern Morocco. AB - Cutaneous leishmaniasis is currently a serious public health problem in northern Africa, especially in Morocco. The causative parasite is transmitted to a human host through the bite of infected female sandflies of the genus Phlebotomus. The objective of the present study is to characterize the causative organisms and to predict the risk of cutaneous leishmaniasis (CL) cases in six provinces in southwestern Morocco, based on the spatial distribution of cases in relation to environmental factors and other risk factors such as socio-economic status and demographics. A molecular study was carried out using ITS1 PCR-RFLP method of the ribosomal DNA of Leishmania. An epidemiological study on CL cases was reported between 2000 and 2016 in this current investigation in six provinces in southwestern Morocco. Statistical analysis was performed using a linear regression model to identify the impact as well as the interaction between all predictor variables on the distribution of CL in the studied provinces. The forecast Holt-Winters (HW) method was used to describe the trend and seasonality of CL cases. The ITS1-PCR- RFLP analysis revealed the presence of Leishmania tropica in all studied provinces. The spatial distribution of CL cases documented in all studied provinces during the sixteen years showed a heterogeneous pattern and fluctuation trend with an average prevalence of 9.92 per 100,000 inhabitants. In addition, the forecast HW model predicts continued variability of trend and seasonality of CL cases in the upcoming years. This study confirmed the importance of socioeconomic factors, in particular poverty and the vulnerability rate, on distribution and emergence of CL. This study revealed a relationship between increasing risk of CL occurrence due to Leishmania tropica, as well as the distribution and emergence thereof, and socioeconomic factors in the investigated area. PMID- 29578085 TI - The macroecology of cancer incidences in humans is associated with large-scale assemblages of endemic infections. AB - It is now well supported that 20% of human cancers have an infectious causation (i.e., oncogenic agents). Accumulating evidence suggests that aside from this direct role, other infectious agents may also indirectly affect cancer epidemiology through interactions with the oncogenic agents within the wider infection community. Here, we address this hypothesis via analysis of large-scale global data to identify associations between human cancer incidence and assemblages of neglected infectious agents. We focus on a gradient of three widely-distributed cancers with an infectious cause: bladder (~2% of recorded cancer cases are due to Shistosoma haematobium), liver (~60% consecutive to Hepatitis B and C infection) and stomach (Helicobacter pylori is associated with ~70% of cases). We analyzed countries in tropical and temperate regions separately, and controlled for many confounding social and economic variables. First, we found that particular assemblages of bacteria are associated with bladder cancer incidences. Second, we observed a specific and robust association between helminths and liver cancer incidences in both biomes. Third, we show that certain assemblages of viruses may facilitate stomach cancer in tropical area, while others protect against its development in temperate countries. Finally, we discuss the implications of our results in terms of cancer prevention and highlight the necessity to consider neglected diseases, especially in tropics, to adapt public health strategies against infectious diseases and cancer. PMID- 29578086 TI - BaTiO3-core Au-shell nanoparticles for photothermal therapy and bimodal imaging. AB - : We report sub-100 nm metal-shell (Au) dielectric-core (BaTiO3) nanoparticles with bimodal imaging abilities and enhanced photothermal effects. The nanoparticles efficiently absorb light in the near infrared range of the spectrum and convert it to heat to ablate tumors. Their BaTiO3 core, a highly ordered non centrosymmetric material, can be imaged by second harmonic generation, and their Au shell generates two-photon luminescence. The intrinsic dual imaging capability allows investigating the distribution of the nanoparticles in relation to the tumor vasculature morphology during photothermal ablation. Our design enabled in vivo real-time tracking of the BT-Au-NPs and observation of their thermally induced effect on tumor vessels. STATEMENT OF SIGNIFICANCE: Photothermal therapy induced by plasmonic nanoparticles has emerged as a promising approach to treating cancer. However, the study of the role of intratumoral nanoparticle distribution in mediating tumoricidal activity has been hampered by the lack of suitable imaging techniques. This work describes metal-shell (Au) dielectric-core (BaTiO3) nanoparticles (abbreviated as BT-Au-NP) for photothermal therapy and bimodal imaging. We demonstrated that sub-100 nm BT-Au-NP can efficiently absorb near infrared light and convert it to heat to ablate tumors. The intrinsic dual imaging capability allowed us to investigate the distribution of the nanoparticles in relation to the tumor vasculature morphology during photothermal ablation, enabling in vivo real-time tracking of the BT-Au-NPs and observation of their thermally-induced effect on tumor vessels. PMID- 29578087 TI - Current approaches in biomaterial-based hematopoietic stem cell niches. AB - : Hematopoietic stem cells (HSCs) are multipotent progenitor cells that can differentiate and replenish blood and immune cells. While there is a growing demand for autologous and allogeneic HSC transplantation owing to the increasing incidence of hereditary and hematologic diseases, the low population of HSCs in cord-blood and bone marrow (the main source of HSCs) hinders their medical applicability. Several cytokine and growth factor-based methods have been developed to expand the HSCs in vitro; however, the expansion rate is low, or the expanded cells fail to survive upon engraftment. This is at least in part because the overly simplistic polystyrene culture substrates fail to fully replicate the microenvironments or niches where these stem cells live. Bone marrow niches are multi-dimensional, complex systems that involve both biochemical (cells, growth factors, and cytokines) and physiochemical (stiffness, O2 concentration, and extracellular matrix presentation) factors that regulate the quiescence, proliferation, activation, and differentiation of the HSCs. Although several studies have been conducted on in vitro HSC expansion via 2D and 3D biomaterial based platforms, additional work is required to engineer an effective biomaterial platform that mimics bone marrow niches. In this study, the factors that regulate the HSC in vivo were explained and their applications in the engineering of a bone marrow biomaterial-based platform were discussed. In addition, current approaches, challenges, and the future direction of a biomaterial-based culture and expansion of the HSC were examined. STATEMENT OF SIGNIFICANCE: Hematopoietic stem cells (HSC) are multipotent cells that can differentiate and replace the blood and immune cells of the body. However, in vivo, there is a low population of these cells, and thus their use in biotherapeutic and medical applications is limited (i.e., bone marrow transplantation). In this review, the biochemical factors (growth factors, cytokines, co-existing cells, ECM, gas concentrations, and differential gene expression) that may regulate the over-all fate of HSC, in vivo, were summarized and discussed. Moreover, different conventional and recent biomaterial platforms were reviewed, and their potential in generating a biomaterial-based, BM niche-mimicking platform for the efficient growth and expansion of clinically relevant HSCs in-vitro, was discussed. PMID- 29578088 TI - RGD/TAT-functionalized chitosan-graft-PEI-PEG gene nanovector for sustained delivery of NT-3 for potential application in neural regeneration. AB - : In this study, we prepared a multifunctional gene delivery nanovector containing a chitosan (CS) backbone and polyethylenimine (PEI) arms with arginine glycine-aspartate (RGD)/twin-arginine translocation (TAT) conjugated via polyethylene glycol (PEG). Branched PEI, with a molecular weight of 2000 Da, was used to achieve a balance between biocompatibility and transfection efficiency, whereas RGD/TAT peptides were conjugated for enhanced targeting ability and cellular uptake. Synthesis of the copolymers was confirmed by characterizing the chemical structure with 1H nuclear magnetic resonance and Fourier Transform Infrared Spectroscopy (FTIR). The nanovector was biocompatible with cells and showed excellent capability for DNA condensation; the resulting complexes with DNA were well-formed, and possessed small particle size and reasonable positive charge. Higher gene transfection efficiency, compared to that achieved with PEI (25 kDa), was confirmed in tumor (HeLa cells) and normal cells (293T and NIH 3T3 cells). More importantly, the cells transfected with the chitosan-graft-PEI PEG/pCMV-EGFP-Ntf3 complex produced sustained neurotrophin-3 with a linear increase in cumulative concentration, which induced neuronal differentiation of neural stem cell and promoted neurite outgrowth. These findings suggested that our multifunctional copolymers might be ideal nanovectors for engineering cells via gene transfection, and could potentially be applied in tumor therapy and regenerative medicine. STATEMENT OF SIGNIFICANCE: We successfully prepared a multifunctional gene delivery nanovector containing branched PEI with a molecular weight of 2000 Da to balance between biocompatibility and transfection efficiency, and RGD/TAT peptides for enhanced targeting ability and cellular uptake. The well-formed CPPP/DNA complexes of small particle size and reasonable positive charges potentially enhanced gene transfection in both tumor and normal cells. More importantly, the CPPP/pCMV-EGFP-Ntf3 complex-transfected 293T cells could produce sustained NT-3 with a constant ratio, which induced neuron differentiation of NSC and promoted neurite outgrowth. Therefore, our study provided an effective strategy for producing neurotrophins by engineering cells with gene delivery, which deserved wide investigation and potential application in regenerative medicine. PMID- 29578089 TI - Research Agenda for the Prevention of Pain and Its Impact: Report of the Work Group on the Prevention of Acute and Chronic Pain of the Federal Pain Research Strategy. AB - : After the 2011 Institute of Medicine report on chronic pain, the Interagency Pain Research Coordinating Committee (IPRCC) was created to enhance research efforts among federal agencies. The IPRCC and Office of Pain Policy at the National Institutes of Health collaborated to identify gaps in knowledge and address them via a Federal Pain Research Strategy (FPRS). Interdisciplinary work groups (WGs) were established to make research recommendations in 5 areas: prevention of acute and chronic pain, acute pain and acute pain management, transition from acute to chronic pain, chronic pain and chronic pain management, and disparities in pain and pain care; cross-cutting issues were also considered. The objective was to provide guidance on current research and to make recommendations about addressing identified gaps. Findings from the Prevention of Acute and Chronic Pain WG are summarized in this article. The WG created subgroups to develop recommendations on specific aspects of prevention of acute and chronic pain, including: public education, primary prevention, secondary prevention, tertiary prevention, transition from acute to chronic pain, and cross cutting mediators. No formal literature review was conducted; however, external advisors were available and consulted as needed. Seven key research priorities were identified. The one deemed "greatest near-term value" was to optimize public health strategies to educate patients on managing pain; that deemed "most impactful" was to determine an association between patient and intervention factors. Other recommendations were related to the epidemiology of acute pain from health care procedures, the epidemiology of acute pain from work-related injuries, safety and effectiveness of management of pain associated with health care procedures, optimizing approaches to acute postsurgical pain, and safety and effectiveness of early interventions for tertiary prevention. Stakeholders, including federally sponsored research programs, researchers, health care providers, policy makers, patients, and others should work together to implement recommendations and address important gaps. PERSPECTIVE: The FPRS Steering Committee created 5 WGs to identify research needs and make recommendations in key areas of research. This article reports the results of one-the Prevention of Acute and Chronic Pain group. Several research priorities emerged, and recommendations made to fill existing knowledge gaps. PMID- 29578090 TI - Effect on Health Care Costs for Adolescents Receiving Adjunctive Internet Delivered Cognitive-Behavioral Therapy: Results of a Randomized Controlled Trial. AB - : The economic burden of pediatric chronic pain is high, with an estimated annual cost of $19.5 billion. Little is known about whether psychological treatment for pediatric chronic pain can alter health care utilization for youth. The primary aim of this secondary data analysis was to evaluate the effect of adjunctive internet cognitive-behavioral therapy intervention or adjunctive internet education on health care-related economic costs in a cohort of adolescents with chronic pain recruited from interdisciplinary pain clinics across the United States. For the full sample, health care expenditures significantly decreased from the year before the intervention to the year after the intervention. Results indicated that the rate of change in health care costs over time was not significantly different between the internet cognitive-behavioral therapy intervention and adjunctive internet education groups. Further research is needed to replicate these findings and determine patterns and drivers of health care costs for youth with chronic pain evaluated in interdisciplinary pain clinics and whether psychological treatments can alter these patterns. This trial was registered at clinicaltrials.gov (identifier NCT01316471). PERSPECTIVE: Health care expenditures significantly decreased in youth with chronic pain from the year before initiating treatment to the following year in both intervention conditions, adjunctive internet cognitive-behavioral therapy and adjunctive internet education. Contrary to our hypothesis, the rate of change in health care costs over time was not significantly different between intervention conditions. PMID- 29578091 TI - Clinicopathological and prognostic significance of the RUNX3 expression in gastric cancer: a systematic review and meta-analysis. AB - BACKGROUND: The relationship between expression of runt related transcription factor 3 (RUNX3) and clinicopathological parameters of the patients with gastric cancer (GC) is controversial. METHODS: The studies were retrieved from those already published essay in PubMed, EMBASE, Wan Fang, CNKI (China National Knowledge Infrastructure), the Cochrane Library and Google Scholar. All statistical tests in this meta-analysis were performed using Stata 10.0 software (Stata Corp, College Station, TX). A P value less than 0.05 was considered statistically significant. RESULTS: A total of nine studies involving 796 patients were included in final meta-analysis. The pooled data showed that expression of RUNX3 was significant correlated with tumor's differentiation (OR = 0.387; 95%CI: 0.237-0.633; P = 0.000), depth of invasion (OR = 0.443; 95%CI: 0.273-0.717; P = 0.001), lymph node metastasis (OR = 0.394; 95%CI: 0.259-0.598; P = 0.000), distant metastasis (OR = 0.403; 95%CI: 0.213-0.764; P = 0.005) and TNM stage (OR = 0.461; 95%CI, 0.322-0.659; P = 0.000) in GC. Expression of RUNX3 was significant correlated with good overall survival (OS) [1-year OS (OR = 2.735; 95%CI: 1.966-3.806; P = 0.000), 3-year OS (OR = 4.782; 95%CI: 3.634-6.292; P = 0.000), 5-year OS (OR = 5.191; 95%CI: 3.775-7.138; P = 0.000]. However, RUNX3 was not correlated with gender (OR = 1.409; 95%CI: 0.986-2.014; P = 0.060). CONCLUSION: RUNX3 expression correlates with tumor's differentiation, depth of invasion, lymph node metastasis, distant metastasis, TNM stage and OS of GC patients. PMID- 29578092 TI - Quercetin dose affects the fate of hepatic ischemia and reperfusion injury in rats: An experimental research. AB - BACKGROUND: Quercetin found in fruits and vegetables has an antioxidative effect. We aimed to investigate the protective effects of quercetin according to different doses on hepatic and ischemia-reperfusion (I/R) injury. METHODS: Fifty mature male Sprague-Dawley rats were randomly divided into five groups (n = 10 for each). All the animal groups underwent laparotomy. Group 1 rats served as a sham-operated group. Groups 2-5 underwent 1 h hepatic ischemia and were followed by 2 h reperfusion. Group 3-5 animals received an additional intraperitoneal dose of 25, 50 or 100 mg/kg quercetin respectively before I/R operation. Blood samples were collected for determining serum aspartate transaminase (AST), alanine transaminase (ALT) and malondialdehyde (MDA) levels. Also, liver tissue samples were taken for measuring of liver MDA concentration and for histopathology assessment. RESULTS: The highest levels of biochemical parameters were observed in group 2. In quercetin-treated groups, serum AST, ALT, MDA levels, and tissue MDA concentration were decreased as inversely with increasing quercetin dose. Microscopic evaluation revealed that most conspicuous histological improvement was observed in 50 mg/kg quercetin co-treated rats. 25 and 100 mg/kg quercetin co treatment could not protect completely against hepatic I/R injury. CONCLUSION: Quercetin can be effective in preventing of hepatic I/R injury when the correct dose was used.

PMID- 29578094 TI - Absorbable versus non-absorbable tacks for mesh fixation in laparoscopic ventral hernia repair: A systematic review and meta-analysis. AB - OBJECTIVES: To investigate the outcomes of absorbable versus non-absorbable tacks in patients undergoing laparoscopic ventral hernia repair. METHODS: We performed a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards. We conducted a search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the Cochrane Central Register of Controlled Trials (CENTRAL); the World Health Organization International Clinical Trials Registry; ClinicalTrials.gov; and ISRCTN Register, and bibliographic reference lists to identify all randomised controlled trials (RCTs) and observational studies investigating outcomes of absorbable versus non absorbable tacks for mesh fixation in patients undergoing laparoscopic ventral hernia repair. We used the Cochrane risk of bias tool and the Newcastle-Ottawa scale to assess the risk of bias of RCTs and observational studies, respectively. Fixed-effect or random-effects models were applied to calculate pooled outcome data. RESULTS: We identified three RCTs and two observational studies enrolling a total of 1149 patients. The included patients were comparable in terms of age [Mean difference (MD) 0.28, 95% confidence intervals (CI) -1.45-2, P = 0.75], male gender (MD 0.81, 95% CI 0.63-1.04, P = 0.10), body mass index (MD -041, 95% CI -1.28-0.46, P = 0.36) and hernia defect size (MD 0.12, 95% CI -0.26-0.49, P = 0.54). The mean and median follow-up period was 30 months and 13 months, respectively There was no difference between the two mesh fixation techniques in terms of recurrence [Risk difference (RD) 0.03, 95% CI -0.04, 0.09, P = 0.47], chronic pain [Odds ratio (OR) 0.91, 95% CI 0.62-1.33, P = 0.64], seroma (OR 0.98, 95% CI 0.37-2.60, P = 0.96), haematoma (RD -0.00, 95% CI -0.04- 0.04, P = 0.99), prolonged ileus (OR 0.99, 95% CI 0.24-4.03, P = 0.99), length of hospital stay (MD 0.10, 95% CI -0.36-0.56, P = 0.68) and port-site hernia (OR 0.98, 95% CI 0.13 7.16, P = 0.98). The operative time was longer in absorbable tack group (MD 7.53, 95% CI 1.49-13.58, P = 0.01). The results remain consistent when randomised trials were analysed separately. CONCLUSIONS: We found no difference in clinical outcomes between absorbable and non-absorbable tacks for mesh fixation in patients undergoing laparoscopic ventral hernia repair. The quality of the available evidence is moderate with a possibility of type 2 error. High quality RCTs with adequate statistical power are required to provide more robust basis for definite conclusions. Considering the similarity of both techniques in terms of clinical outcomes, the cost-effectiveness of each technique would be an important outcome determining which technique should be used; this needs to be considered as an outcome of interest in future studies. PMID- 29578095 TI - The impact of improving teamwork on patient outcomes in surgery: A systematic review. AB - BACKGROUND: The aviation industry pioneered formalised crew training in order to improve safety and reduce consequences of non-technical error. This formalised training has been successfully adapted and used to in the field of surgery to improve post-operative patient outcomes. The need to implement teamwork training as an integral part of a surgical programme is increasingly being recognised. We aim to systematically review the impact of surgical teamwork training on post operative outcomes. METHODS: Two independent researchers systematically searched MEDLINE and Embase in accordance with PRISMA guidelines. Studies were screened and subjected to inclusion/exclusion criteria. Study characteristics and outcomes were reported and analysed. RESULTS: Our initial search identified 2720 articles. Following duplicate removal, title and abstract screening, 107 full text articles were analysed. Eight articles met our inclusion criteria. Overall, three articles supported a positive effect of good teamwork on post-operative patient outcomes. We identified key areas in study methodology that can be improved upon, including small cohort size, lack of unified training programme, and short training duration, should future studies be designed and implemented in this field. CONCLUSION: At present, there is insufficient evidence to support the hypothesis that teamwork training interventions improve patient outcomes. We believe that non-significant and conflicting results can be attributed to flaws in methodology and non-uniform training methods. With increasing amounts of evidence in this field, we predict a positive association between teamwork training and patient outcomes will come to light. PMID- 29578096 TI - Perioperative blood transfusion has no effect on overall survival after esophageal resection for esophageal squamous cell carcinoma: A retrospective cohort study. AB - BACKGROUND: The impact of perioperative blood transfusion (PBT) on the prognosis of esophageal cancer patients remains inconclusive. The purpose of this study was to assess the association between PBT and survival in esophageal squamous cell carcinoma (ESCC) patients. MATERIALS AND METHODS: In this retrospective study, patients with ESCC who underwent esophageal resection from January 2008 to December 2011 were analyzed. The overall survival and postoperative outcomes between PBT and non-PBT patients were compared using Cox regression and propensity score matching (PSM) analysis. RESULTS: A total of 935 patients were enrolled in this study. Before PSM, the 5-year overall survival rates in PBT and non-PBT patients were 48.4% and 56.3% (P = 0.001), respectively. The postoperative infection rate in PBT patients was 32.32%, which exceeded the rate of 24.22% in non-PBT patients (P = 0.008). PSM created 306 pairs of patients. After PSM, the 5-year overall survival rates in PBT and non-PBT patients were 49.4% and 51.0% (P = 0.334), respectively. The postoperative infection rate in PBT patients was 31.04%, which was higher than the rate of 26.47% in non-PBT patients (P = 0.105). Multivariable Cox regression analyses showed that PBT was not an independent risk factor for overall survival (HR: 0.792, 95% CI: 0.615 1.021, P = 0.072). CONCLUSION: Perioperative blood transfusion has no effect on the overall survival of ESCC patients. PMID- 29578098 TI - Influencers and preference predictors of HPV vaccine uptake among US male and female young adult college students. AB - OBJECTIVE: The purpose of the study was to assess the knowledge, attitudes and beliefs of male and female college students in Kentucky about HPV associated diseases and vaccines, and to determine which parameters predicted self-reported uptake of HPV vaccination. MATERIALS AND METHODS: A self-selected cross-sectional sample of college students completed an evidence-based online survey. RESULTS: Of approximately 1200 potential respondents, 585 completed the survey. The average age was 20.6 (SD 3.15) and 78% were female; 84% of the population had had one or more sexual partners. Concern for HPV vaccine safety and potential need for boosters did not significantly deter vaccine uptake. Likewise, knowledge about HPV associated cancers was not predictive of vaccine uptake. On the other hand, parental influence for vaccination was a strong predictor for vaccine uptake (aOR = 5.32, 2.71-13.03), and free vaccine nearly doubled the likelihood of being vaccinated (aOR 1.90, 1.05-3.41). In addition, the strong preference for the respondent's partner to be HPV vaccinated predicted vaccine uptake (aOR = 4.04, 95% CI: 2.31-7.05), but the lack of preference for partner vaccination predicted an unvaccinated self (aOR = 0.50, 0.27-0.93). CONCLUSIONS: HPV vaccination has been successful in young adult college students in Kentucky. Young adults prefer their partners to be HPV vaccinated regardless of whether they themselves are vaccinated. Parental influence and free vaccine were positive predictors for vaccine uptake in this population. PMID- 29578097 TI - Are two doses of human papillomavirus vaccine sufficient for girls aged 15-18 years? Results from a cohort study in India. AB - Extending two-dose recommendations of HPV vaccine to girls between 15 and 18 years will reduce program cost and improve compliance. Immunogenicity and vaccine targeted HPV infection outcomes were compared between 1795 girls aged 15-18 years receiving two (1-180 days) and 1515 girls of same age receiving three (1-60-180 days) doses. Immunogenicity outcomes in 15-18 year old two-dose recipients were also compared with the 10-14 year old three-dose (N = 2833) and two-dose (N = 3184) recipients. The 15-18 year old two-dose recipients had non-inferior L1 binding antibody titres at seven months against vaccine-targeted HPV types compared to three-dose recipients at 15-18 years and three-dose recipients at 10 14 years of age. Neutralizing antibody titres at 18 months in 15-18 year old two dose recipients were non-inferior to same age three-dose recipients for all except HPV 18. The titres were inferior to those in the 10-14 year old three-dose recipients for all targeted types. Frequency of incident infections from vaccine targeted HPV types in the 15-18 year old two-dose recipients was similar to the three dose recipients. None of the girls receiving two or three doses had persistent infection from vaccine-targeted types. These findings support that two doses of HPV vaccine can be extended to girls aged 15-18 years. PMID- 29578099 TI - miR2Pathway: A novel analytical method to discover MicroRNA-mediated dysregulated pathways involved in hepatocellular carcinoma. AB - MicroRNAs (miRNAs) are small, non-coding RNAs involved in the regulation of gene expression at a post-transcriptional level. Recent studies have shown miRNAs as key regulators of a variety of biological processes, such as proliferation, differentiation, apoptosis, metabolism, etc. Aberrantly expressed miRNAs influence individual gene expression level, but rewired miRNA-mRNA connections can influence the activity of biological pathways. Here, we define rewired miRNA mRNA connections as the differential (rewiring) effects on the activity of biological pathways between hepatocellular carcinoma (HCC) and normal phenotypes. Our work presented here uses a PageRank-based approach to measure the degree of miRNA-mediated dysregulation of biological pathways between HCC and normal samples based on rewired miRNA-mRNA connections. In our study, we regard the degree of miRNA-mediated dysregulation of biological pathways as disease risk of biological pathways. Therefore, we propose a new method, miR2Pathway, to measure and rank the degree of miRNA-mediated dysregulation of biological pathways by measuring the total differential influence of miRNAs on the activity of pathways between HCC and normal states. miR2Pathway proposed here systematically shows the first evidence for a mechanism of biological pathways being dysregulated by rewired miRNA-mRNA connections, and provides new insight into exploring mechanisms behind HCC. Thus, miR2Pathway is a novel method to identify and rank miRNA-dysregulated pathways in HCC. PMID- 29578100 TI - Wisdom of artificial crowds feature selection in untargeted metabolomics: An application to the development of a blood-based diagnostic test for thrombotic myocardial infarction. AB - INTRODUCTION: Heart disease remains a leading cause of global mortality. While acute myocardial infarction (colloquially: heart attack), has multiple proximate causes, proximate etiology cannot be determined by a blood-based diagnostic test. We enrolled a suitable patient cohort and conducted a non-targeted quantification of plasma metabolites by mass spectrometry for developing a test that can differentiate between thrombotic MI, non-thrombotic MI, and stable disease. A significant challenge in developing such a diagnostic test is solving the NP-hard problem of feature selection for constructing an optimal statistical classifier. OBJECTIVE: We employed a Wisdom of Artificial Crowds (WoAC) strategy for solving the feature selection problem and evaluated the accuracy and parsimony of downstream classifiers in comparison with traditional feature selection techniques including the Lasso and selection using Random Forest variable importance criteria. MATERIALS AND METHODS: Artificial Crowd Wisdom was generated via aggregation of the best solutions from independent and diverse genetic algorithm populations that were initialized with bootstrapping and a random subspaces constraint. RESULTS/CONCLUSIONS: Strong evidence was observed that a statistical classifier utilizing WoAC feature selection can discriminate between human subjects presenting with thrombotic MI, non-thrombotic MI, and stable Coronary Artery Disease given abundances of selected plasma metabolites. Utilizing the abundances of twenty selected metabolites, a leave-one-out cross validation estimated misclassification rate of 2.6% was observed. However, the WoAC feature selection strategy did not perform better than the Lasso over the current study. PMID- 29578101 TI - Diagnostic accuracy of multiplex real-time PCR approaches compared with cultivation -based detection methods: Monitoring the endopathogenic microbiota pre and post photo-activated disinfection. AB - BACKGROUND: Several microbial species have been implicated in the pathogenesis of endodontic diseases that colonize the infected root canal system. Since the complete removal of endopathogenic agents is essential in endodontic infection therapy, photo-activated disinfection (PAD) is suggested as an alternative method to traditional antimicrobial therapy. Recent studies reported that the molecular methods with low sensitivity and high efficiency to identify fastidious anaerobic endopathogenic microbiota can be replaced by the cultivation-based approaches. This study aimed to validate the multiplex real-time PCR in order to identify six common microorganisms associated with the endodontic infections before and after the PAD. MATERIALS AND METHODS: Microbial specimens from the root canals of 50 patients with primary and secondary endodontic infections were collected before PAD treatment using sterile paper points. Toluidine blue O (TBO)-mediated PAD was performed on the root canals, followed by resampling. The prePAD- and postPAD treatment endodontic samples were transferred to a transport medium and six target microorganisms were then identified from the samples using the microbiological culture techniques and multiplex real-time PCR approach. RESULTS: Multiplex real-time PCR could represent the presence of all target microorganisms in 100% cases before and after the PAD. Before PAD, using the culture method, Enterococcus faecalis (100%) was found to be the most frequent, followed by Veillonella parvula (97.5%), Aggregatibacter actinomycetemcomitans (94.7%), Porphyromonas gingivalis (84.3%), Lactobacillus rhamnosus (84.3%), and Actinomyces naeslundii (66.6%); whereas, after PAD these microbial frequencies changed to 80%, 83.3%, 66.6%, 80%, 66.6%, and 33.3%, respectively. The sensitivity and negative predictive value of the multiplex real-time PCR were 100% before and after the PAD, whereas the highest and the lowest specificities were 100% and 82% before PAD, and 97% and 89% after PAD for E. faecalis and P. gingivalis, respectively. The highest (100%) and the lowest (66%) positive predictive values were for V. parvula and A. naeslundii before and after the PAD, respectively. CONCLUSION: As observed from the results, multiplex real-time PCR demonstrated high sensitivity and specificity when compared to the culture technique. Therefore, it can prove to be a highly sensitive technique to detect the endodontic infections microflora. PMID- 29578102 TI - Secondary prevention of chronic musculoskeletal pain: A systematic review of clinical trials. AB - BACKGROUND: Chronic musculoskeletal pain disorders are highly prevalent and have high personal and societal cost. Hence, early detection and care of patients at risk of developing chronic pain is important. Risk factors are well known and screening tools exist, but much less is known about the care of at-risk patients. The aim of this study was to investigate the effectiveness of secondary prevention strategies for musculoskeletal pain. METHODS: We performed a systematic review of clinical trials in which treatments were adjusted to the risk of chronicity in adults with acute or subacute musculoskeletal pain. Clinical trials, systematic reviews and meta-analyses published after January 1, 2000 were searched in PubMed and PEDro databases and in the reference list of relevant papers. The risk of bias was assessed by the PEDro score. RESULTS: We identified 4807 potentially eligible articles; 13, corresponding to 9 studies, met the inclusion criteria. Most studies investigated low back pain. The overall risk of bias was moderate, mainly because of the difficulty of blinding in physiotherapy studies. As compared with a "one-size-fits-all" treatment, stratified programmes showed significant improvements in several domains of the International Classification of Functioning, Disability and Health: body structures and functions (pain, mood), activities (functional capacity), participation (return to work, quality of life), as well as environmental factors (healthcare consumption). Effect sizes were moderate. Overall, simple educational messages seemed sufficient for low-risk patients. Medium- and high-risk patients benefited from a physical reactivation programme combined with education. In high risk patients, an additional cognitive-behavioural intervention further improved the outcome. CONCLUSIONS: A stratified approach seems effective in reducing long term disability in patients with musculoskeletal pain. However, more research is necessary to confirm these results. PMID- 29578103 TI - Acute bronchodilator therapy does not reduce wasted ventilation during exercise in COPD. AB - This randomized, double-blind, crossover study aimed to determine if acute treatment with inhaled bronchodilators, by improving regional lung hyperinflation and ventilation distribution, would reduce dead space-to-tidal volume ratio (VD/VT); thus contributing to improved exertional dyspnea in COPD. Twenty COPD patients (FEV1 = 50 +/- 15% predicted; mean +/- SD) performed pulmonary function tests and symptom-limited constant-work rate exercise at 75% peak-work rate (with arterialized capillary blood gases) after nebulized bronchodilator (BD; ipratropium 0.5mg + salbutamol 2.5 mg) or placebo (PL; normal saline). After BD versus PL: Functional residual capacity decreased by 0.4L (p = .0001). Isotime during exercise after BD versus PL (p < .05): dyspnea decreased: 1.2 +/- 1.9 Borg units; minute ventilation increased: 3.8 +/- 5.5 L/min; IC increased: 0.24 +/- 0.28 L and VT increased 0.19 +/- 0.16 L. There was no significant difference in arterial CO2 tension or VD/VT, but alveolar ventilation increased by 3.8 +/- 5.5 L/min (p = .02). Post-BD improvements in respiratory mechanics explained 51% of dyspnea reduction at a standardized exercise time. Bronchodilator-induced improvements in respiratory mechanics were not associated with reduced wasted ventilation - a residual contributory factor to exertional dyspnea during exercise in COPD. PMID- 29578104 TI - Impact of operative time on early joint infection and deep vein thrombosis in primary total hip arthroplasty. AB - PURPOSE: Infections and deep vein thrombosis (DVT) after total hip arthroplasty (THA) are challenging problems for both the patient and surgeon. Previous studies have identified numerous risk factors for infections and DVT after THA but have often been limited by sample size. We aimed to evaluate the effect of operative time on early postoperative infection as well as DVT rates following THA. We hypothesized that an increase in operative time would result in increased odds of acquiring an infection as well as a DVT. METHODS: We conducted a retrospective analysis of prospectively collected data using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database from 2006 to 2015 for all patients undergoing primary THA. Associations between operative time and infection or DVT were evaluated with multivariable logistic regressions controlling for demographics and several known risks factors for infection. Three different types of infections were evaluated: (1) superficial surgical site infection (SSI), an infection involving the skin or subcutaneous tissue, (2) deep SSI, an infection involving the muscle or fascial layers beneath the subcutaneous tissue, and (3) organ/space infection, an infection involving any part of the anatomy manipulated during surgery other than the incisional components. RESULTS: In total, 103,044 patients who underwent THA were included in our study. Our results suggested a significant association between superficial SSIs and operative time. Specifically, the adjusted odds of suffering a superficial SSI increased by 6% (CI=1.04-1.08, p<0.0001) for every 10-minute increase of operative time. When using dichotomized operative time (<90minutes or >90minutes), the adjusted odds of suffering a superficial SSI was 56% higher for patients with prolonged operative time (CI=1.05-2.32, p=0.0277). The adjusted odds of suffering a deep SSI increased by 7% for every 10-minute increase in operative time (CI=1.01-1.14, p=0.0335). No significant associations were detected between organ/space infection, wound dehiscence, or DVT and operative time either as continuous or as dichotomized. CONCLUSION: Prolonged operative times (>90min) are associated with increased rates of superficial SSIs, but not deep SSIs, organ/space infections, wound dehiscence, or DVT. LEVEL OF EVIDENCE: III. PMID- 29578105 TI - Arthroscopy-assisted Trillat procedure for anterior shoulder instability: Surgical technique and preliminary clinical results. AB - The Trillat procedure performed as open surgery to treat anterior shoulder instability has been proven effective in preventing recurrences and restoring range of motion. An arthroscopically assisted variant of the Trillat procedure is described here, together with the preliminary clinical results in 18 patients treated between 2011 and 2014. After a mean follow-up of 24.7+/-9.8 months, the clinical outcomes were very satisfactory, with a Walch-Duplay score of 81.5+/ 18.0, a Rowe score of 83.6+/-16.0, and 94% of satisfied or very satisfied patients. Mean operative time was 55+/-13min. No recurrences were recorded. As an easily performed procedure that provides good clinical outcomes, the arthroscopically assisted Trillat procedure is a simple and reproducible alternative to arthroscopic Latarjet procedure, which is still reserved for highly experienced surgical teams. PMID- 29578106 TI - Two-team management of vascular injuries concomitant with osteo-articular injuries in 36 patients over six years. AB - BACKGROUND: Patients with both vascular and osteoarticular injuries require multidisciplinary management. Vascular injuries may be function- and/or life threatening. The lower limbs are predominantly affected. Traffic, domestic, and work-related accidents contribute most of the cases. The primary objective of this study was to describe the management of patients with concomitant vascular and osteo-articular injuries, with special attention to the rates of amputation and fasciotomy. The secondary objective was to suggest a management sequence to optimise our surgical practice. HYPOTHESIS: The management sequence is a crucial consideration in patients with both vascular and osteo-articular injuries. MATERIAL AND METHODS: A 6-year, retrospective, observational study was conducted in patients with concomitant vascular and osteo-articular injuries. RESULTS: The study included 36 patients with a mean age of 40.6+/-22.1 years. The main sources of injury were traffic accidents (n=19, 52.8%), crush injury (n=8, 22.2%), and falls (n=5, 13.9%). A compound fracture was present in 20 (55.6%) patients. Evidence of ischaemia in 25 (69.4%) patients, and bleeding in 11 (30.6%) patients. Pre-operative imaging, by ultrasonography or computed tomography, was performed in 27 (75.0%) patients. The lower limb was involved in 30 (83.3%) patients, who had osteoarticular injuries to the femur and leg combined with injury to the popliteal artery. Fasciotomy was performed in 11 (30.6%) patients and secondary amputation in 7 (19.4%) patients. The limb salvage rate was 80.6%. Median patient survival was 9.3 [0-74.8] months. DISCUSSION: Coordinated work by two surgical teams is crucial to manage concomitant vascular and osteo-articular injuries. The management sequence must be defined clearly. Computed tomography angiography is the investigation of choice and should be performed at the slightest suspicion of vascular injury. LEVEL OF EVIDENCE: IV, retrospective observational study. PMID- 29578107 TI - Clinical Features and Management of Acquired Resistance to PD-1 Axis Inhibitors in 26 Patients With Advanced Non-Small Cell Lung Cancer. AB - INTRODUCTION: With expanding indications for programmed death 1 (PD-1) axis inhibitors in non-small cell lung cancer (NSCLC), acquired resistance (AR) to these therapies is increasingly being encountered. We sought to characterize clinical patterns of AR to PD-1 axis inhibitors in patients with advanced NSCLC, and evaluate subsequent outcome and management strategies for such patients. METHODS: Patients with NSCLC who developed AR to PD-1 axis inhibitor therapy initiated between December 2009 and February 2016 at one institution were identified and examined by clinical and radiographic features. AR was defined as progressive disease after initial response by either Response Evaluation Criteria in Solid Tumors v1.1 or immune-related response criteria. RESULTS: Twenty-six patients with AR to PD-1 axis inhibitor therapy were identified and evaluated. Median time to AR was 313 days; the 2-year survival rate from AR was 70% (95% confidence interval: 0.53-0.92). Twenty patients (77%) experienced AR in lymph nodes (LNs), including 11 patients with LN-only progression. Twenty-three (88%) patients had recurrence limited to one (54%) or two (35%) sites of disease. Fourteen patients (54%) continued PD-1 axis inhibitor therapy beyond progression. Three patients were re-challenged with the same PD-1 axis inhibitor after holiday from and progression off therapy, 2 again responded. Fifteen patients (58%) received local therapy to site(s) of AR, 11 continued respective PD-1 axis inhibitor after local therapy. The 2-year survival rate from AR among these 15 patients was 92% (95% confidence interval: 0.77-1). CONCLUSIONS: Acquired resistance to PD-1 axis inhibitors is often limited to one or two sites when local therapy and continuation of PD-1 axis inhibitor therapy can result in prolonged benefit. LN metastases appear to be particularly susceptible sites to AR. When progression of disease following response occurs after holiday from PD-1 axis inhibitor, re-challenge can again lead to tumor regression. PMID- 29578109 TI - Center variation in episode-of-care costs for adult spinal deformity surgery: results from a prospective, multicenter database. AB - BACKGROUND CONTEXT: Adult spinal deformity (ASD) surgery is associated with significant resource utilization, costing more than $958 million in charges for Medicare patients and more than $1.7 billion in charges for managed care population in the last decade. Given the recent move toward bundled payment models, it is important to understand the various care components a patient receives over the course of a defined clinical episode, its associated cost, and the proportion of cost for each component toward the bundled payment. PURPOSE: To examine the degree and determinants of variation in inpatient episode-of-care (EOC) cost, resource utilization, and patient-reported outcomes for patients undergoing ASD surgery across four spine deformity centers in the United States. STUDY DESIGN/SETTING: Retrospective analysis of prospective, multicenter database. PATIENT SAMPLE: Consecutive patients enrolled in an ASD database from four spinal deformity centers. OUTCOME MEASURES: Total in-patient EOC costs and Short Form (SF)-6D. METHODS: The study used a multicenter database of 210 consecutively enrolled operative patients from 2008 to 2013 at four participating centers in the United States. Demographic, surgical, and direct cost data, expressed in 2013 dollars, for the entire inpatient EOC were obtained from administrative databases from the respective hospitals. Mixed models and multivariable linear regression were used to evaluate the impact of center on total costs adjusting for patient characteristics, length of stay (LOS), and surgical factors. RESULTS: A total of 126 patients with complete baseline and 2 year follow-up data were included. The percentages of patients from each center were 36.5%, 7.1%, 24.6%, and 31.7%. Overall, the mean patient age was 58.4+/-12.6 years, 86% were women, and 94% were Caucasian. The proportion of total cost variation explained by the center at which the patient was treated was 17%. After adjusting for patient, LOS, and surgical factors the cost variation reduced to 4%. In multivariable analysis, each additional level fused increased total cost variation by $2,500, whereas recombinant human bone morphogenetic protein-2 (BMP) use and posterior-only surgical approach lowered total EOC costs by $10,500 and $9,400, respectively. No significant difference was observed in 2-year quality adjusted life year across centers. CONCLUSIONS: Total EOC costs for ASD surgery varied significantly by center. Levels fused, BMP use, and surgical approach were the primary drivers of cost variation across centers. Differences in resource utilization had no impact on 2-year quality-adjusted life year improvement across centers. PMID- 29578108 TI - Initiative for Early Lung Cancer Research on Treatment: Development of Study Design and Pilot Implementation. AB - INTRODUCTION: To maximize the benefits of computed tomographic screening for lung cancer, optimal treatment for small, early lung cancers is needed. Limiting the extent of surgery spares lung tissue, preserves pulmonary function, and decreases operative time, complications, and morbidities. It also increases the likelihood of resecting future new primary lung cancers. The goal is to assess alternative treatments in a timely manner. METHODS: The focus sessions with patients and physicians separately highlighted the need to consider their perceptions. Literature reviews and analyses of treatment results using large databases were performed to formulate critical questions about long-term treatment outcomes, recurrence, and quality of life of alternative treatments. Based on these analyses, the investigators developed a prospective multi-institutional cohort study, the Initiative for Early Lung Cancer Research for Treatment, to compare treatments for stage I NSCLC. HIPAA compliant institutional review board approval was obtained and we performed a feasibility study of the first 206 surgical patients. RESULTS: Lobectomy was performed in 89 (43.2%) patients, and sublobar resection was performed in 117 (56.7%) patients. Mediastinal lymph node resection was performed in 173 (84.0%) patients, 8 had N1 and 3 N2 lymph node metastases. Patients stated that both the surgeon's opinion (93%) and the patient's own opinion (93%) were extremely important, followed by the patients' view that the chosen procedure would provide the best quality of life (90%). CONCLUSIONS: It was feasible to obtain pre- and postsurgical information from patients and surgeons. We anticipate statistically meaningful results about treatment alternatives in 3 to 5 years. PMID- 29578110 TI - Spontaneous correction of coronal imbalance after selective thoracolumbar-lumbar fusion in patients with Lenke-5C adolescent idiopathic scoliosis. AB - BACKGROUND CONTEXT: Coronal imbalance is a complication of corrective surgeries in adolescent idiopathic scoliosis (AIS). However, few studies about immediate coronal decompensation in Lenke-5C curves have reported its incidence, prognosis, and related factors. PURPOSE: To evaluate the development of coronal imbalance after selective thoracolumbar-lumbar (TL/L) fusion (SLF) in Lenke-5C AIS, and to reveal related factors. STUDY DESIGN: Retrospective comparative study. PATIENT SAMPLE: This study included 50 consecutive patients with Lenke-5C AIS who underwent SLF at a single center. OUTCOME MEASURES: Whole-spine anteroposterior and lateral radiographs were used to measure radiological parameters. METHODS: Patients were divided into two groups according to the presence or absence of coronal imbalance (distance between C7 plumb line and central sacral vertical line >2 cm) in the early (1 month) postoperative period. Various radiological parameters were statistically compared between groups. RESULTS: Of the patients, 28% (14 of 50) showed coronal imbalance in the early postoperative period; however, most of them (13 of 14) showed spontaneous correction during follow-up. The development of coronal imbalance was related to less flexibility of the TL/L curve (51.3% vs. 52.6%, p=.040), greater T10-L2 kyphosis (11.7 degrees vs. 6.4 degrees , p=.034), and greater distal junctional angle (6.0 degrees vs. 3.7 degrees , p=.025) in preoperative radiographs. Lowermost instrumented vertebra (LIV) tilt was greater in the decompensation [+] group in the early postoperative period (8.8 degrees vs. 4.4 degrees , p=.009). However, this difference disappeared in final follow-up with the decrease of LIV tilt in the decompensation [+] group. CONCLUSIONS: Less flexibility of the TL/L curve, greater TL kyphosis, and greater distal junctional angle preoperatively were predictive factors for immediate coronal imbalance in Lenke-5C curves. Although coronal imbalance was frequently detected in the early postoperative period after SLF, it was mostly corrected spontaneously with a decrease of LIV tilt. Thus, SLF for Lenke-5C curves can be a good option regardless of the possible coronal imbalance in the early postoperative period.

AB - A nanoscale linear permittivity imaging method based on scanning nonlinear dielectric microscopy (SNDM) was developed. The ?C/?z-mode SNDM (?C/?z-SNDM) technique described herein employs probe-height modulation to suppress disturbances originating from stray capacitance and to improve measurement stability. This method allows local permittivity distributions to be examined with extremely low noise levels (approximately 0.01 aF) by virtue of the highly sensitive probe. A cross-section of a multilayer oxide film was visualized using ?C/?z-SNDM as a demonstration, and numerical simulations of the response signals were conducted to gain additional insights. The experimental signal intensities were found to be in a good agreement with the theoretical values, with the exception of the background components, demonstrating that absolute sample permittivity values could be determined. The signal profiles near the boundaries between different dielectrics were calculated using various vibration amplitudes and the boundary transition widths were obtained. The beneficial aspects of higher-harmonic response imaging are discussed herein, taking into account assessments of spatial resolution and quantitation.

AB - In a two dimensional free electron gas subjected to a perpendicular spatially varying magnetic field, the classical paths of electrons are snake-like trajectories that weave along the line where the field crosses zero. But quantum mechanically this system is described by a symmetric double well potential which, for low excitations, leads to very different electron behavior. We compute the spectrum, as well as the wavefunctions, for states of definite parity in the limit of nearly degenerate states, i.e. for electrons sufficiently far from the B z = 0 line. Transitions between the states are shown to give rise to a tunneling current. If the well is made asymmetrical by a time-dependent parity breaking perturbation then Rabi-like oscillations between parity states occur. Resonances can be excited and used to stimulate the transfer of electrons from one side of the potential barrier to the other through quantum tunneling.

AB - Passive magnetic shielding refers to the use of ferromagnetic materials to redirect magnetic field lines away from vulnerable regions. An application of particular interest to the medical physics community is shielding in MRI systems, especially integrated MRI-linear accelerator (MRI-Linac) systems. In these systems, the goal is not only to minimize the magnetic field in some volume, but also to minimize the impact of the shield on the magnetic fields within the imaging volume of the MRI scanner. In this work, finite element modelling was used to assess the shielding of a side coupled 6 MV linac and resultant heterogeneity induced within the 30 cm diameter of spherical volume (DSV) of a novel 1 Tesla split bore MRI magnet. A number of different shield parameters were investigated; distance between shield and magnet, shield shape, shield thickness, shield length, openings in the shield, number of concentric layers, spacing between each layer, and shield material. Both the in-line and perpendicular MRI Linac configurations were studied. By modifying the shield shape around the linac from the starting design of an open ended cylinder, the shielding effect was boosted by approximately 70% whilst the impact on the magnet was simultaneously reduced by approximately 10%. Openings in the shield for the RF port and beam exit were substantial sources of field leakage; however it was demonstrated that shielding could be added around these openings to compensate for this leakage. Layering multiple concentric shield shells was highly effective in the perpendicular configuration, but less so for the in-line configuration. Cautious use of high permeability materials such as Mu-metal can greatly increase the shielding performance in some scenarios. In the perpendicular configuration, magnetic shielding was more effective and the impact on the magnet lower compared with the in-line configuration.

AB - Determining the electric potential in a bent piezoelectric nanowire (NW) is a fundamental issue of nanogenerators and nanopiezotronics. The combined influence of the flexoelectric effect, the semiconducting performance and the angle of atomic force microscope (AFM) tip has never been studied previously and will be investigated in this paper. The exact solution for the electric potential of a bent piezoelectric semiconductor NW is derived. The electric potential of the present model with consideration of flexoelectric effect varies along the length of the NW and is different from that of the classical piezoelectric model. Flexoelectric effect enhances but the semiconducting performance reduces the electric potential of the NW. In addition, it is found that if the angle of the AFM tip reaches 30 degrees , the error of the electric potential obtained from the model ignored the effect of the angle of the AFM tip is almost 16%, which is unacceptable.

AB - Prostate cancer is characterized by bone metastases and difficulty of objectively measuring disease burden. In this context, cell-free circulating tumor DNA (ctDNA) and circulating tumor cell (CTC) quantitation and genomic profiling afford the ability to noninvasively and serially monitor the tumor. Recent data suggest that ctDNA and CTC quantitation are prognostic for survival. Indeed, CTC enumeration using the CellSearch(r) platform is validated as a prognostic factor and warrants consideration as a stratification factor in randomized trials. Changes in quantities of CTCs using CellSearch also are prognostic and may be employed to detect a signal of activity of new agents. Molecular profiling of both CTCs and ctDNA for androgen receptor (AR) variants has been associated with outcomes in the setting of novel androgen inhibitors. Serial profiling to detect the evolution of new alterations may inform drug development and help develop precision medicine. The costs of these assays and the small quantities in which they are detectable in blood are a limitation, and novel platforms are required to address this challenge. The presence of multiple platforms to assay CTCs and ctDNA also warrants the consideration of a mechanism to allow comparison of data across platforms. Further validation and the continued development and standardization of these promising modalities will facilitate their adoption in the clinic.

AB - This study was performed to investigate a potential marker for the presence of spermatozoa in the ejaculate following varicocelectomy in Chinese men with nonobstructive azoospermia and varicoceles. The micro-RNA (miR)-192a levels in seminal plasma and testicular tissue were evaluated by quantitative real-time polymerase chain reaction from 60 men with nonobstructive azoospermia and varicoceles (Group A: 27 men with spermatozoa found in the ejaculate after surgery; Group B: 33 men without spermatozoa found in the ejaculate after surgery) and 30 controls. The seminal plasma and testicular tissue miR-192a levels were higher in Group B than in Group A and the controls (P < 0.001), and there was no significant difference between Group A and the controls (P > 0.05). Apoptosis and proliferation assays with miR mimics and inhibitors showed that miR 192a induced GC-2 cell apoptosis through the activation of Caspase-3 protein. Thus, seminal plasma miR-192a appears to be a potential marker for successfully indicating spermatozoa in the ejaculate following microsurgical varicocelectomy in men with nonobstructive azoospermia and varicoceles. Seminal plasma miR-192a may be a useful clinical marker for prescreening to determine which patients with nonobstructive azoospermia and varicoceles would benefit from varicocelectomy.

AB - Background: It is known that there is a definite association between platelet distribution width (PDW) and poor prognosis in patients with coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM). However, there are no data available regarding the prognostic significance of PDW for in-stent restenosis (ISR) in patients with CAD and T2DM. We aimed to determine the value of PDW on admission that predicted ISR in patients with CAD and T2DM. Methods: Between January 2012 and December 2013, a total of 5232 consecutive patients diagnosed with CAD and T2DM undergoing percutaneous coronary intervention were admitted. Three years of retrospective follow-up was undertaken. A total of 438 patients with second angiography operations were included. ISR was defined as >=50% luminal stenosis of the stent or peri-stent segments. Continuous data were presented as the mean +/- standard deviation or median (P25, P75) and were compared by one-way analysis of variance or Kruskal-Wallis H-test. Categorical variables were presented as percentages and were compared by Chi-square test or Fisher's exact test. The association between PDW and ISR was calculated by logistic regression analysis. A two-sided value of P < 0.05 was considered statistically significant. Statistical analyses were performed by SPSS version 22.0 for windows. Results: Fifty-nine patients with ISR, accounting for 13.5% of the total, were included. ISR was significantly more frequent in patients with higher PDW quartiles compared with lower quartiles. We observed that PDW had a strong relationship with mean platelet volume (r = 0.647, 95% confidence interval [CI]: 0.535-0.750, P < 0.0001). The receiver-operating characteristic curves showed that the PDW cutoff value for predicting ISR rate was 13.65 fl with sensitivity of 59.3% and specificity of 72.4% (area under curve [AUC] = 0.701, 95% CI: 0.625-0.777, P < 0.001). Multivariate analysis showed that the risk of ISR increased approximately 30% when PDW increased one unit (odds ratio [OR]: 1.289, 95% CI: 1.110-1.498, P = 0.001). Patients with higher PDW, defined as more than 13.65 fl, had a 4-fold higher risk of ISR compared with lower PDW (OR: 4.241, 95% CI: 1.879-9.572, P = 0.001). Furthermore, when patients were divided by PDW quartiles values, PDW was able to predict ISR (Q2: OR = 0.762, 95% CI: 0.189-3.062, P = 0.762; Q3: OR = 2.782, 95% CI: 0.865-8.954, P = 0.086; and Q4: OR = 3.849, 95% CI: 1.225-12.097, P = 0.021, respectively; P for trend <0.0001). Conclusion: PDW is an independent predictor of ISR in patients with CAD and T2DM. PMID- 29578118 TI - Low-Dose Unfractionated Heparin with Sequential Enoxaparin in Patients with Diabetes Mellitus and Complex Coronary Artery Disease during Elective Percutaneous Coronary Intervention. AB - Background: Despite its limitations, unfractionated heparin (UFH) has been the standard anticoagulant used during percutaneous coronary intervention (PCI). This study compared the safety of low-dose UFH with sequential enoxaparin with that of UFH in patients with diabetes mellitus (DM) and complex coronary artery disease receiving elective PCI. Methods: In this retrospective study, 514 consecutive patients with atherosclerotic cardiovascular diseases and type 2 DM were admitted to the hospital and received selective PCI, from January 2013 to December 2015. All patients with PCI received low-dose UFH with enoxaparin (intraductal 50 U/kg UFH and 0.75 mg/kg enoxaparin, n = 254; UFH-Enox group) or UFH only (intraductal 100 U/kg UFH, n = 260; UFH group). The study endpoints were major adverse cardiac events (MACEs), namely death, myocardial infarction (MI), stroke, target-vessel immediate revascularization (TVR), and thrombolysis in MI (TIMI) major bleeding, within 30 days and 1 year after PCI. Any catheter thrombosis during the procedure was recorded. Results: Only one patient had an intraductal thrombus in the UFH group. At the 30-day follow-up, no MACE occurred in any group; seven and five cases of recurrent angina and/or rehospitalization were reported in the UFH-Enox and UFH groups, respectively; there was no significant difference between the two groups (chi2 = 0.11, P = 0.77). There was no TIMI major bleeding in the groups. With respect to the 1-year endpoint, two cases of recurrent MI and two of TVRs were reported in the UFH-Enox group, whereas in the UFH group, one case of recurrent MI and three of TVRs were reported; no significant difference existed between the two groups (chi2 = 0, P = 0.99). There were 30 and 25 recurrent angina and/or rehospitalizations in the UFH-Enox and UFH groups, respectively; there was no significant difference between the two groups (chi2 = 0.37, P = 0.57). Conclusion: In elective PCI, low-dose UFH with sequential enoxaparin has similar effects and safety to the UFH-only method. PMID- 29578119 TI - Molecular Analysis-Based Genetic Characterization of a Cohort of Patients with Duchenne and Becker Muscular Dystrophy in Eastern China. AB - Background: Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are common X-linked recessive neuromuscular disorders caused by mutations in dystrophin gene. Multiplex polymerase chain reaction (multiplex PCR) and multiplex ligation-dependent probe amplification (MLPA) are the most common methods for detecting dystrophin gene mutations. This study aimed to contrast the two methods and discern the genetic characterization of patients with DMD/BMD in Eastern China. Methods: We collected 121 probands, 64 mothers of probands, and 15 fetuses in our study. The dystrophin gene was detected by multiplex PCR primarily in 28 probands, and MLPA was used in multiplex PCR-negative cases subsequently. The dystrophin gene of the remaining 93 probands and 62 female potential carriers was tested by MLPA directly. In fetuses, multiplex PCR and MLPA were performed on 4 fetuses and 10 fetuses, respectively. In addition, sequencing was also performed in 4 probands with negative MLPA. Results: We found that 61.98% of the subjects had genetic mutations including deletions (50.41%) and duplications (11.57%). There were 43.75% of mothers as carriers of the mutation. In 15 fetuses, 2 out of 7 male fetuses were found to be unhealthy and 2 out of 8 female fetuses were found to be carriers. Exons 3-26 and 45-52 have the maximum frequency in mutation regions. In the frequency of exons individually, exon 47 and exon 50 were the most common in deleted regions and exons 5, 6, and 7 were found most frequently in duplicated regions. Conclusions: MLPA has better productivity and sensitivity than multiplex PCR. Prenatal diagnosis should be applied in DMD high-risk fetuses to reduce the disease incidence. Furthermore, it is the responsibility of physicians to inform female carriers the importance of prenatal diagnosis. PMID- 29578120 TI - Central Nervous System Involvement in Hemophagocytic Lymphohistiocytosis in Adults: A Retrospective Analysis of 96 Patients in a Single Center. AB - Background: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening clinical syndrome. Central nervous system (CNS) involvement is a severe complication, which can lead to rapid disease development and higher morality. However, this has not been given enough attention in adult HLH. Therefore, we carried out this study to analyze the clinical features, laboratory findings, treatment outcomes, and other characteristics of adult HLH with CNS involvement. Methods: A retrospective analysis of 96 adult patients with HLH combined with CNS involvement between June 2003 and December 2016 was conducted. Clinical features, cerebrospinal fluid (CSF) features, image changes, and therapeutic outcomes were analyzed. Results: Among the 96 patients, 86 had various CNS symptoms and 33 (38.4%) had already presented symptoms before the HLH diagnosis was confirmed. A total of 59 patients received CSF examinations and showed abnormalities in 23 patients (39.0%). Seventy patients received imaging examinations and the results showed fifty patients with imaging changes (71.4%). Fifty-seven patients received multiple rounds of repeated intrathecal injection therapy and 35 patients improved (61.4%). As for the multiple analyses of effective factors on survival time, the results showed that the effects of combined Epstein-Barr virus (EBV) infection (P = 0.026, Exp(B) = 2.309, 95% confidence interval [CI] [1.108, 4.823) and intrathecal injection therapy (P = 0.013, Exp(B) = 0.422, 95% CI [0.214, 0.831]) on the survival time of the CNS-HLH patients were significant. Conclusions: Complication with EBV infection is a risk factor, and intrathecal injection is a protective factor. CNS involvement in HLH is not rare, which can result in a poor prognosis. Multiple rounds of repeated intrathecal injection therapy can improve the prognosis of CNS-HLH patients. PMID- 29578121 TI - A Retrospective Study Comparing Surgical and Early Oncological Outcomes between Intracorporeal and Extracorporeal Ileal Conduit after Laparoscopic Radical Cystectomy from a Single Center. AB - Background: Robot-assisted/laparoscopic intracorporeal ileal conduit (ICIC) has been reported in many experienced centers. Whether laparoscopic ICIC is superior to extracorporeal ileal conduit (ECIC) and whether laparoscopic ICIC should be promoted is still controversial. The aim of the study was to compare surgical and early oncological outcomes between patients undergoing laparoscopic radical cystectomy (LRC) with ICIC and ECIC. Methods: From January 2011 to June 2016, a total of 45 patients with bladder cancer underwent LRC with ileal conduit at our department, of whom 20 patients underwent LRC with ECIC and 25 patients underwent LRC with ICIC. Data of each patient's characteristics, surgical outcomes, and short-term oncological outcomes were collected and analyzed. Results: LRC with ileal conduit was performed successfully on all 45 patients. There were no significant differences in patients' characteristics, mean total operative time, and mean estimated blood loss between the ICIC and ECIC groups. Median time of flatus and oral intake was shorter in the ICIC group compared with the ECIC group (3 vs. 5 days, P = 0.035; 4 vs. 5 days, P = 0.002). The complications rates did not show significant difference between the two groups within the first 90 days postoperatively (P = 0.538). Cancer staging showed 45% of patients in the ECIC group and 36% in the ICIC group had a pathologic stage of T3 or T4, and 50% of patients in the ECIC group and 44% in the ICIC group had a pathologic stage of N1 or N1+. Kaplan-Meier analysis showed no significant difference in overall survival at 24 months (60% vs. 62%, P = 0.857) between the ECIC and ICIC groups. Conclusions: ICIC after LRC may be successful with the benefits of faster recovery time. No significant difference was found in complications and oncological outcomes between ICIC and ECIC. However, larger series with longer follow-up are needed to validate this procedure. PMID- 29578122 TI - Efficacy and Safety of Unmanipulated Haploidentical Related Donor Allogeneic Peripheral Blood Stem Cell Transplantation in Patients with Relapsed/Refractory Acute Myeloid Leukemia. AB - Background: Studies of haploidentical-related donor (HRD) stem cell transplantation using a combination of peripheral blood stem cells (PBSCs) and bone marrow as the graft have reported encouraging results for patients with hematological diseases. However, few studies specifically reported transplantation of only PBSCs from HRDs among patients with relapsed or refractory acute myeloid leukemia (AML). Here, the long-term outcomes and side effects of unmanipulated HRD PBSC transplantation (HRD-PBSCT) for relapsed/refractory AML were analyzed. Methods: We performed a retrospective analysis of the outcomes in relapsed/refractory AML patients who underwent PBSCT from HRDs (n = 36). Results: Thirty-one (86.1%) patients in the HRD-PBSCT group achieved platelet recovery. The cumulative incidence of acute graft-versus-host disease (aGVHD) in the HRD-PBSCT group was 40.00%, and the cumulative incidence of grades 2-4 aGVHD in this group was 13.33%. A total of 13 patients in the HRD PBSCT group had recurrent disease at a median of 183 days after transplantation (range: 10-1700 days), reaching cumulative incidences of relapse of 50.28% at 5 years. On multivariate analysis, donor age and patient age >40 years were independent risk factors for inferior disease-free survival or overall survival (P < 0.05). The results of the present study demonstrate rapid and complete neutrophil engraftment, a low incidence of grade 2-4 aGVHD, and promising survival rates in patients after HRD-PBSCT. Thus, granulocyte colony-stimulating factor-primed PBSCs may be a reliable graft source in unmanipulated HRD-HSCT under myeloablative conditioning when no matched sibling donor is available. Conclusions: Our results support the feasibility, effectiveness, and tolerability of PBSCs as a graft source in unmanipulated HRD transplantation under myeloablative conditioning in patients with leukemia. PMID- 29578123 TI - A Novel SLC20A2 Mutation Associated with Familial Idiopathic Basal Ganglia Calcification and Analysis of the Genotype-Phenotype Association in Chinese Patients. AB - Background: Idiopathic basal ganglia calcification (IBGC) is a genetic disorder characterized by bilateral basal ganglia calcification and neural degeneration. In this study, we reported a new SLC2OA2 mutation of IBGC and reviewed relevant literature to explore the association between phenotypes and genotypes in Chinese IBGC patients. Methods: Clinical information of the proband and her relatives were collected comprehensively. Blood samples of both the patient and her father were obtained, and genetic screening related to IBGC was performed using second generation sequencing with their consent. Findings were confirmed by Sanger sequencing. Polyphen-2 was used to predict the potential association between mutations and disease. Then, we retrieved literatures of Chinese IBGC patients and explored the association between phenotype and genotype. Results: A novel mutation was identified through genetic testing, and it is suggested to be a damage mutation predicted by Polyphen-2. Through literature review, we found that SLC20A2 mutation is the most common cause for IBGC in China. Its hot spot regions are mainly on the 1st and 8th exons; the second common one is PDGFB where the hot spot covered a length of 220-230 bp localized on the 2nd exon; moreover, Chinese IBGC patients featured early-onset, more severe movement disorder and relatively mild cognitive impairment compared with those in other countries. Conclusions: There is significant heterogeneity both in phenotype and genotype in Chinese IBGC patients. Further research of pathogenic mechanism of IBGC is required to eventually develop precise treatment for individuals who suffered this disease. PMID- 29578124 TI - Role of glutamine in the mediation of E-cadherin, p120-catenin and inflammation in ventilator-induced lung injury. AB - Background: Ventilator-induced lung injury (VILI) is commonly associated with barrier dysfunction and inflammation reaction. Glutamine could ameliorate VILI, but its role has not been fully elucidated. This study examined the relationship between inflammatory cytokines (interleukin [IL]-6, tumor necrosis factor [TNF] alpha, and IL-10) and adherens junctions (E-cadherin, p120-catenin), which were ameliorated by glutamine in VILI, both in vitro and in vivo. Methods: For the in vivo study, 30 healthy C57BL/6 mice weighing 25-30 g were randomly divided into five groups with random number table (n = 6 in each group): control (Group C); low tidal volume (Group L); low tidal volume + glutamine (Group L + G); high tidal volume (Group H); and high tidal volume + glutamine (Group H + G). Mice in all groups, except Group C, underwent mechanical ventilation for 4 h. For the in vitro study, mouse lung epithelial 12 (MLE-12) cells pretreated with glutamine underwent cyclic stretching at 20% for 4 h. Cell lysate and lung tissue were obtained to detect the junction proteins, inflammatory cytokines, and lung pathological changes by the Western blotting, cytokine assay, hematoxylin and eosin staining, and immunofluorescence. Results: In vivo, compared with Group C, total cell counts (t = -28.182, P < 0.01), the percentage of neutrophils (t = 28.095, P < 0.01), IL-6 (t = -28.296, P < 0.01), and TNF-alpha (t = -19.812, P < 0.01) in bronchoalveolar lavage (BAL) fluid, lung injury scores (t = -6.708, P < 0.01), and the wet-to-dry ratio (t = -15.595, P < 0.01) were increased in Group H; IL-10 in BAL fluid (t = 9.093, P < 0.01) and the expression of E-cadherin (t = 10.044, P < 0.01) and p120-catenin (t = 13.218, P < 0.01) were decreased in Group H. Compared with Group H, total cell counts (t = 14.844, P < 0.01), the percentage of neutrophils (t = 18.077, P < 0.01), IL-6 (t = 18.007, P < 0.01), and TNF-alpha (t = 10.171, P < 0.01) in BAL fluid were decreased in Group H + G; IL-10 in BAL fluid (t = -7.531, P < 0.01) and the expression of E-cadherin (t = 14.814, P < 0.01) and p120-catenin (t = -9.114, P < 0.01) were increased in Group H + G. In vitro, compared with the nonstretching group, the levels of IL-6 (t = 21.111, P < 0.01) and TNF-alpha (t = -15.270, P < 0.01) were increased in the 20% cyclic stretching group; the levels of IL-10 (t = 5.450, P < 0.01) and the expression of E-cadherin (t = 17.736, P < 0.01) and p120-catenin (t = 16.136, P < 0.01) were decreased in the 20% cyclic stretching group. Compared with the stretching group, the levels of IL-6 (t = 11.818, P < 0.01) and TNF-alpha (t = 8.631, P < 0.01) decreased in the glutamine group; the levels of IL-10 (t = 3.203, P < 0.05) and the expression of E-cadherin (t = -13.567, P < 0.01) and p120-catenin (t = -10.013, P < 0.01) were increased in the glutamine group. Conclusions: High tidal volume mechanical ventilation and 20% cyclic stretching could cause VILI. Glutamine regulates VILI by improving cytokines and increasing the adherens junctions, protein E-cadherin and p120-catenin, to enhance the epithelial barrier function. PMID- 29578125 TI - In vitro Effects of Nerve Growth Factor on Cardiac Fibroblasts Proliferation, Cell Cycle, Migration, and Myofibroblast Transformation. AB - Background: Recent research indicates that nerve growth factor (NGF) promotes cardiac repair following myocardial infarction by promoting angiogenesis and cardiomyocyte survival. The purpose of this study was to investigate the effects of NGF on cardiac fibroblasts (CFs) proliferation, cell cycle, migration, and myofibroblast transformation in vitro. Methods: CFs were obtained from ventricles of neonatal Sprague-Dawley rats and incubated with various concentrations of NGF (0, 0.01, 0.1, 1, 10, and 100 ng/ml; 0 ng/ml was designated as the control group). Cell proliferation and cell cycle of the CFs were measured by 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry (FCM), respectively. A cell scratch wound model and transwell were carried out to observe effects of NGF on migration of CFs after 24 h of culture. Real-time polymerase chain reaction (RT-PCR) and Western blotting were used to measure alpha-smooth muscle actin (alpha-SMA) at mRNA and protein levels after CFs were incubated with various concentrations of NGF. Results: Expression of alpha-SMA measured by RT-PCR and Western blotting significantly increased in the 1 and 10 ng/ml NGF groups (P < 0.05). Absorbance values of CFs showed that NGF did not influence the proliferation of CFs (The A490values were 0.178 +/- 0.038, 0.182 +/ 0.011, 0.189 +/- 0.005, 0.178 +/- 0.010, 0.185 +/- 0.025, and 0.177 +/- 0.033, respectively, in the 0, 0.01, 0.1, 1, 10, and 100 ng/ml NGF groups [P = 0.800, 0.428, 0.981, 0.596, and 0.913, respectively, compared with control group]), and FCM analysis showed that the percentage of CFs in G0/G1, S, and G2/M phases was not changed (P > 0.05). The cell scratch wound model and transwell showed that CFs migration was not significantly different (P > 0.05). Conclusion: NGF induces myofibroblast transformation but does not influence proliferation, cell cycle, or migration of CFs in vitro.

AB - Background: Mineral and bone disorder is one of the severe complications in kidney transplant recipients (KTRs). Previous studies showed that bisphosphonates had favorable effects on bone mineral density (BMD). We sought to compare different bisphosphonate regimens and rank their strategies. Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) up to April 01, 2017, for randomized controlled trials (RCTs) comparing bisphosphonate treatments in adult KTRs. The primary outcome was BMD change. We executed the tool recommended by the Cochrane Collaboration to evaluate the risk of bias. We performed pairwise meta-analyses using random effects models and network meta-analysis (NMA) using Bayesian models and assessed the quality of evidence. Results: A total of 21 RCTs (1332 participants) comparing 6 bisphosphonate regimens were included. All bisphosphonates showed a significantly increased percentage change in BMD at the lumbar spine compared to calcium except clodronate. Pamidronate with calcium and Vitamin D analogs showed improved BMD in comparison to clodronate with calcium (mean difference [MD], 9.84; 95% credibility interval [CrI], 1.06-19.70). The combination of calcium and Vitamin D analogs had a significantly lower influence than adding either pamidronate or alendronate (MD, 6.34; 95% CrI, 2.59-11.01 and MD, 6.16; 95% CrI, 0.54-13.24, respectively). In terms of percentage BMD change at the femoral neck, both pamidronate and ibandronate combined with calcium demonstrated a remarkable gain compared with calcium (MD, 7.02; 95% CrI, 0.30-13.29 and MD, 7.30; 95% CrI, 0.32 14.22, respectively). The combination of ibandronate with calcium displayed a significant increase in absolute BMD compared to any other treatments and was ranked best. Conclusions: Our NMA suggested that new-generation bisphosphonates such as ibandronate were more favorable in KTRs to improve BMD. However, the conclusion should be treated with caution due to indirect comparisons. PMID- 29578127 TI - Mindfulness Meditation for Primary Headache Pain: A Meta-Analysis. AB - Background: Several studies have reported that mindfulness meditation has a potential effect in controlling headaches, such as migraine and tension-type headache; however, its role remains controversial. This review assessed the evidence regarding the effects of mindfulness meditation for primary headache pain. Methods: Only English databases (PubMed, Cochrane Central Register of Controlled Trials [the Cochrane Library], PsycINFO, Psychology and behavioral science collection, PsyArticles, Web of Science, and Scopus) were searched from their inception to November 2016 with the keywords ("meditation" or "mindfulness" or "vipassana" or "dzogchen" or "zen" or "integrative body-mind training" or "IBMT" or "mindfulness-based stress reduction" or "MBSR" or "mindfulness-based cognitive therapy" or "MBCT" and "Headache" or "Head pain" or "Cephalodynia" or "Cephalalgia" or "Hemicrania" or "Migraine"). Titles, abstracts, and full-text articles were screened against study inclusion criteria: controlled trials of structured meditation programs for adult patients with primary headache pain. The quality of studies included in the meta-analysis was assessed with the Yates Quality Rating Scale. The meta-analysis was conducted with Revman 5.3. Results: Ten randomized controlled trials and one controlled clinical trial with a combined study population of 315 patients were included in the study. When compared to control group data, mindfulness meditation induced significant improvement in pain intensity (standardized mean difference, -0.89; 95% confidence interval, -1.63 to -0.15; P = 0.02) and headache frequency (-0.67; 1.24 to -0.10; P = 0.02). In a subgroup analysis of different meditation forms, mindfulness-based stress reduction displayed a significant positive influence on pain intensity (P < 0.000). Moreover, 8-week intervention had a significant positive effect (P < 0.000). Conclusions: Mindfulness meditation may reduce pain intensity and is a promising treatment option for patients. Clinicians may consider mindfulness meditation as a viable complementary and alternative medical option for primary headache. PMID- 29578129 TI - DNA Methylation and Uveal Melanoma. AB - Objective: The objective of the study was to summarize the role of DNA methylation in the development and metastasis of uveal melanoma (UM). Data Sources: The relevant studies in MEDLINE were searched. Study Selection: In this review, we performed a comprehensive literature search in MEDLINE using "uveal melanoma" AND ("DNA methylation" OR "epigenetics") for original research/review articles published before February 2018 on the relationship between DNA methylation and UM. References of the retrieved studies were also examined to search for potentially relevant papers. Results: Previous studies on the relationship between DNA methylation and UM covered many genes including tumor suppressor genes (TSGs), cyclin-dependent kinase genes, and other genes. Among them, the TSG genes such as RASSF1A and p16INK4a, which encodes a cyclin dependent kinase inhibitor, are relatively well-studied genes. Specifically, a high percentage of promoter methylation of RASSF1A was observed in UM cell lines and/or patients with UM. Promoter methylation of RASSF1A was also associated with the development of metastasis. Similarly, a high percentage of promoter hypermethylation of p16INK4a was found in UM cell lines. DNA promoter methylation can control the expression of p16INK4a, which affect cell growth, migration, and invasion in UM. Many other genes might also be involved in the pathogenesis of UM such as the Ras and EF-hand domain containing (RASEF) gene, RAB31, hTERT, embryonal fyn-associated substrate, and deleted in split-hand/split-foot 1. Conclusions: Our review reveals the complex mechanisms underlying the tumorigenesis of UM and highlights the great needs of future studies to discover more genes/5'-C-phosphate-G-3' sites contributing to the development/metastasis of UM and explore the mechanisms through which epigenetic changes exert their function in UM. PMID- 29578128 TI - Hydrogen Sulfide Regulating Myocardial Structure and Function by Targeting Cardiomyocyte Autophagy. AB - Objective: Hydrogen sulfide (H2S), a gaseous signal molecule, plays a crucial role in many pathophysiologic processes in the cardiovascular system. Autophagy has been shown to participate in the occurrence of many cardiac diseases. Increasing evidences indicated that H2S regulates myocardial structure and function in association with the altered autophagy and plays a "switcher" role in the autophagy of myocardial diseases. The aim of this review was to summarize these insights and provide the experimental evidence that H2S targets cardiomyocyte autophagy to regulate cardiovascular function. Data Sources: This review was based on data in articles published in the PubMed databases up to October 30, 2017, with the following keywords: "hydrogen sulfide," "autophagy," and "cardiovascular diseases." Study Selection: Original articles and critical reviews on H2S and autophagy were selected for this review. Results: When autophagy plays an adaptive role in the pathogenesis of diseases, H2S restores autophagy; otherwise, when autophagy plays a detrimental role, H2S downregulates autophagy to exert a cardioprotective function. For example, H2S has beneficial effects by regulating autophagy in myocardial ischemia/reperfusion and plays a protective role by inhibiting autophagy during the operation of cardioplegia and cardiopulmonary bypass. H2S postpones cardiac aging associated with the upregulation of autophagy but improves the left ventricular function of smoking rats by lowering autophagy. Conclusions: H2S exerts cardiovascular protection by regulating autophagy. Cardiovascular autophagy would likely become a potential target of H2S therapy for cardiovascular diseases.

AB - Objective: Since the advent of induced pluripotent stem cell (iPSC) technology a decade ago, enormous progress has been made in stem cell biology and regenerative medicine. Human iPSCs have been widely used for disease modeling, drug discovery, and cell therapy development. In this review, we discuss the progress in applications of iPSC technology that are particularly relevant to drug discovery and regenerative medicine, and consider the remaining challenges and the emerging opportunities in the field. Data Sources: Articles in this review were searched from PubMed database from January 2014 to December 2017. Study Selection: Original articles about iPSCs and cardiovascular diseases were included and analyzed. Results: iPSC holds great promises for human disease modeling, drug discovery, and stem cell-based therapy, and this potential is only beginning to be realized. However, several important issues remain to be addressed. Conclusions: The recent availability of human cardiomyocytes derived from iPSCs opens new opportunities to build in vitro models of cardiac disease, screening for new drugs and patient-specific cardiac therapy.

AB - Side effects associated with conventional anticancer therapies have prompted the new idea of solid tumor treatment strategy. One of them is using bacteria explored as potential antitumor agents over more than one century. Notably, the ideal therapy is a specifical target to tumors with limited toxicity. Here, we take "Clostridium novyi" for the search keyword in the PubMed from 2000 to 2015 and describe that C. novyi-NT spores act as "Trojan horse" for bacteriolytic therapy. This therapy is based on the fact that the live and attenuated obligate anaerobic bacteria are capable of binary fission selectively in anoxic areas of solid tumors and direct tumoricidal effects. Our succinct review mainly concentrates on the potential mechanisms of combination bacteriolytic therapy, an effective and safe tumor therapy with the help of C. novyi-NT. Importantly, C. novyi-NT spores were shown to induce solid tumor regression and exhibit the property to initiate an immune response. Therefore, C. novyi-NT spores should be an effective and safe tumor therapy. PMID- 29578143 TI - The relationship of indoor coal use and environmental tobacco smoke exposure with lung cancer in China: A meta-analysis. AB - Objective: To assess the association between long-term exposures to smoky coal, environmental tobacco smoke (ETS) and lung cancer incidence in China. Methods: A meta-analysis was performed on literature searched through Web of Science, Chinese National Knowledge Infrastructure, Weipu, and Wanfang databases. Odds ratio (OR) with 95% confidence intervals (CIs) was used to assess the strength of association between air pollution and lung cancer in China. Results: Twenty-eight studies were included in the meta-analysis. Stratification by ETS exposure source, amount, and gender found a variation in effect. The pooled OR (95% CI) for exposure to spousal, parents, and work ETS was 1.153 (1.000-1.329), 2.117 (1.626-2.755), and 1.454 (1.307-1.618), respectively. The OR (95% CI) values related to childhood exposure was 1.297 (1.142-1.473), adulthood exposure 1.102 (0.937-1.296), exposure lower than 20 cigarette/day 1.088 (0.809-1.464), higher than 20 cigarette/day 1.776 (1.392-2.267), male 1.555 (1.304-1.855), female 1.487 (1.265-1.748), and coal use 1.490 (1.330-1.669). Conclusion: The meta-analysis provided evidence that indoor coal use and ETS were significantly associated with lung cancer in China. PMID- 29578144 TI - Transdermal fentanyl for cancer pain: Trial sequential analysis of 3406 patients from 35 randomized controlled trials. AB - Objective: The aim of this study was to assess the effectiveness and safety of transdermal fentanyl for the treatment of moderate or severe cancer-related pain. Materials and Methods: Electronic databases including PubMed, Embase, the Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, the Chinese Biomedical Literature Database, and Chongqing Weipu and Wanfang Database were searched for relevant studies published prior to January 2015. Only randomized controlled trials on the use of the transdermal fentanyl patch for the treatment of cancer pain were selected. Two reviewers independently screened the studies and extracted data. The quality assessment of the studies included was based on the Cochrane Handbook for Systematic Reviews of Interventions (version 5.1.0). RevMan 5 (version 5.3) and Trial Sequential Analysis software (TSA, version 2.1, provided by Copenhagen Trial Unit, Denmark) were used for data analyses. Results: A total of 35 studies involving 3406 participants met the inclusion criteria for this meta-analysis. There was no statistically significant difference with regard to the effectiveness of management for cancer pain between the use of transdermal fentanyl patch and oral morphine (risk ratio = 1.00, 95% confidence interval, 0.97-1.03, P > 0.05). TSA results demonstrated that the cumulative Z-score crossed its monitoring boundaries, and therefore, reliable conclusions had been drawn. Moreover compared with oral morphine, the use of transdermal fentanyl patch resulted in statistically significantly decreased incidence of constipation, nausea and vomiting, drowsiness, and urinary retention. There was a significantly greater incidence of skin irritation in patients who used a transdermal fentanyl patch (P < 0.05). Conclusions: The findings from this study demonstrate that use of transdermal fentanyl for the management of moderate or severe cancer pain had more advantages compared to oral morphine. PMID- 29578145 TI - Identifying key genes in retinoblastoma by comparing classifications of several kinds of significant genes. AB - Objective: The objective of this paper was to investigate key genes in retinoblastoma using a novel method which is mainly based on five kinds of genes, differentially expressed genes (DEGs), differential pathway genes (DPGs), seed genes (common genes between DEGs and DPGs), hub genes and informative genes (common genes of hub genes and DEGs), and support vector machines (SVM) model. Materials and Methods: In the proposed method, the first step was to identify five types of significant genes. DEGs were identified using linear models for microarray data (Limma) package (The Walter and Eliza Hall Institute of Medical Research, Melbourne, Australia). DPGs were originated from differential pathways based on attract method. Hub genes of mutual information network which is constructed by the context likelihood of relatedness algorithm were obtained according to topological degree centrality analysis. For the second step, SVM model was implemented to assess the classification performance of DEGs, DPGs, seed genes, hub genes, and informative genes, depending on its induces the area under the receiver operating characteristics curve (AUC), true negative rate (TNR), true positive rate (TPR) and the Matthews coefficient correlation classification (MCC). Results: We detected 479 DEGs, 747 DPGs, 29 seed genes, 34 hub genes, and 7 informative genes in total for retinoblastoma. The classification performance of informative genes was the best of all with AUC = 1.00, TNR = 1.00, TPR = 1.00, and MCC = 1.00, hence they were considered to key genes which included EPARS1, FN1, HLA-DPA1, HLA-DPB1, HLA-DRA, CFI, and transforming growth factor, beta receptor II. Conclusions: We have successfully identified seven key genes, which might be potential biomarkers for detection and therapy of retinoblastoma for current and future study. PMID- 29578146 TI - Human epidermal growth factor receptor 2, epidermal growth factor receptor, and c MET overexpression and survival in biliary tract cancer: A meta-analysis. AB - Background: Tyrosine kinase growth factor receptors (TKGFRs) play an important role in the progression of cancer. A variety of studies have investigated the clinicopathologic correlation of these receptors and their influences on patient survival in different types of cancer. As the members of TKGFRs, the biomarkers c MET, epidermal growth factor receptor (EGFR), and human epidermal growth factor receptor 2 (HER-2) have been extensively investigated in biliary tract cancer (BTC). However, their prognostic value is still controversial. Our study aimed to evaluate the prognostic significance of the three markers in BTC patients based on the published studies. The correlation between high expression of these markers and clinical parameters or overall survival (OS) has been assumed in this paper. Materials and Methods: Including PubMed, EMBASE, China National Knowledge Infrastructure, and Springer, a comprehensive search for the related literature published in Chinese and English has been done. Finally, 31 studies were selected in our research. Results: Surprisingly, the meta-analysis indicated that HER-2 high expression was not correlated with age, gender, primary tumor, tumor node metastasis (TNM) stage, lymph node status, and differentiation. We also found that EGFR high expression was not associated with the parameters, such as age, gender, TNM stage, differentiation, or lymph node status. c-MET high-expression was not associated with age, differentiation, gender, TNM stage, or lymph node status. In addition, our study showed that HER-2, EGFR, and c-MET high expression had an adverse influence on OS in BTC, the pooled hazard ratio for HER-2, EGFR, and c-MET was statistically significant. Conclusion: The present meta-analysis indicated that EGFR and HER-2 high expression have little impact on OS in patients with BTC while c-MET high expression influenced OS in patients with BTC to a large extent. However, c-MET, EGFR, and HER-2 expression did not show any correlation with those clinical parameters. c-MET may be a potential therapeutic target for BTC. PMID- 29578147 TI - Comparison of the efficacy of strontium-89 chloride in treating bone metastasis of lung, breast, and prostate cancers. AB - Objective: The aim of this study was to comparatively evaluate the efficacy of strontium-89 chloride (89 SrCl2) in treating bone metastasis-associated pain in patients with lung, breast, or prostate cancer. Materials and Methods: The 126 patients with lung cancer included 88, 16, 15, 4, and 3 patients with adenocarcinoma, squamous cell carcinoma, nonsmall cell carcinoma, mixed carcinoma, and small cell carcinoma, respectively, and the control group consisted of patients with breast (71 patients) or prostate cancer (49 patients) who underwent 89 SrCl2 treatment during the same period. The treatment dose of 89 SrCl2 was 2.22 MBq/kg. Results: The efficacy rate of treatment in the lung cancer group was 75.4%, compared to 95.0% in the control group. Approximately 67% of patients with lung cancer and bone metastases and 47% of control patients exhibited mild-to-moderate reductions of leukocyte and platelet counts 4 weeks after 89 SrCl2 treatment. Conclusions: 89 SrCl2 can safely and effectively relieve bone pain caused by bone metastasis from lung cancer. However, its efficacy was lower in patients with lung cancer with bone metastasis than in those with breast or prostate cancer with bone metastasis, and its effects on the peripheral hemogram were also significantly stronger in the lung cancer group. PMID- 29578148 TI - Effect of inhibition of intermediate-conductance-Ca2+-activated K+ channels on HeLa cell proliferation. AB - Purpose: To explore the influence of intermediate-conductance-Ca2+-activated K+ channels. (IKCal) on HeLa cell proliferation. Materials and Methods: An IKCal blocking agent (clotrimazole (CLT)) and small hairpin ribonucleic acid interference (RNAi) was used to block IKCal in HeLa cells; subsequently, cell growth was observed. Furthermore, the messenger ribonucleic acid (mRNA) expression of IKCal was detected by reverse transcriptase polymerase chain reaction (RT-PCR) after IKCal-blocking. Results: The obvious morphological changes in HeLa cells were observed 48 h after CLT-blocking. The PCR results indicated that CLT reduced the mRNA expression of IKCal in HeLa cells. HeLa cells were transfected with pGenesil via RNAi; the HeLa cells transfected with pGenesil IK displayed obvious morphological changes 48 h after transfection. In addition, RT-PCR further demonstrated the reduced mRNA expression of IKCal in the pGenesil group. Conclusion: CLT and blocking of IKCal gene expression effectively inhibits HeLa cell proliferation; therefore, the use of a blocking agent and RNAi both effectively downregulated the mRNA expression of IKCal, which in turn mediated the proliferation of HeLa cells, producing an antitumor effect. PMID- 29578149 TI - Hypoxia-inducible factor-1alpha rs11549465 C>T and rs11549467 G>A gene polymorphisms are associated with an increased risk of digestive cancers in Asians. AB - Objective: We used a meta-analysis framework to examine the correlation between HIF-1alpha gene polymorphisms and the susceptibility to digestive cancers. Methods: Cochrane Library Database, EMBASE, MEDLINE, Pubmed, CINAHL, Chinese Biomedical Database and Web of Science were searched without language restrictions to identify relevant case-control studies reporting data on HIF 1alpha gene polymorphisms in digestive cancers. Data was extracted from the selected studies and meta-analysis was carried out using STATA 12.0 and Comprehensive Meta-analysis 2.0 softwares. Relative risk (RR) and its 95% confidence interval (95%CI) were calculated. A total of 8 eligible case-control studies were included. These 8 studies contained a combined total of 1,276 patients diagnosed with various digestive cancers and 3,392 healthy controls. Two functional HIF-1alpha polymorphisms (rs11549465 C>T and rs11549467 G>A) were examined in these 8 studies. Results: Our findings demonstrated that both rs11549465 C>T and rs11549467 G>A HIF-1alpha polymorphisms conferred significantly increased risk of digestive cancers. However, ethnicity-stratified analysis revealed that HIF-1alpha rs11549465 C>T and rs11549467 G>A polymorphisms were associated with an elevated risk of digestive cancer in Asians, but not in Caucasians. These two polymorphisms also conferred different degrees of susceptibility to various digestive cancer types. Conclusion: Our meta-analysis suggests that HIF-1alpha rs11549465 C>T and rs11549467 G>A polymorphisms influence the pathogenesis of digestive cancers in Asians. PMID- 29578150 TI - Elevated expression of matrix metalloproteinase-9 is associated with bladder cancer pathogenesis. AB - Objective: This study investigated the association between abnormal matrix metalloproteinase-9 (MMP-9) expression and bladder cancer (BC) development. Materials and Methods: In a retrospective analysis, this study used tissue samples derived from 92 patients pathologically diagnosed with BC (experimental group), who were hospitalized between September 2012 and June 2014 at the Urinary Surgery of Department of Urology, Lanzhou University Second Hospital. As controls (control group), 63 normal pericancerous bladder mucosal tissues (3 cm distant form edge of BC foci) with confirmed pathology were selected from the same time period. Immunohistochemistry was employed to detect MMP-9 protein expression in the tissues and enzyme-linked immunosorbent assay was performed to measure MMP-9 protein levels in tissue samples of patients and control subjects. Finally, a meta-analysis was conducted to understand the overall impact of MMP-9 on BC pathogenesis. STATA 12.0 software (Stata Corp, College Station, TX, USA) was used for all statistical analyses. Results: The MMP-9 positive expression rate in tissue samples and MMP-9 levels were significantly greater in the experimental group compared to the control group (both P < 0.001). The frequency of MMP-9 positive status showed statistically significant differences between G1 (low grade) and G3 (high-grade) (P < 0.001), between G2 and G3 (P < 0.05), and between G1/G2 and G3 (P = 0.001). Our meta-analysis findings provided further evidence that MMP-9 positive expression status and MMP-9 levels in the experimental group were significantly higher than the control group (positive expressions: Odds ratio [OR] = 18.59, 95% confidence interval [95% CI] = 11.63-29.71, P < 0.001; expression levels: Standard mean difference = 1.51, 95%CI = 0.63-2.39, P = 0.001). The positive expression status of MMP-9 was notably lower in G1/G2 compared to G3 (OR = 0.24, 95%CI = 0.15-0.36, P < 0.001). Conclusion: Our study demonstrated that both positive expression status in tumor tissue and expression levels of MMP-9 are significantly elevated in BC patients and correlate with disease progression. Thus, MMP-9 can serve as a biomarker to determine the degree of BC malignancy. PMID- 29578151 TI - MiR-186 inhibits cell proliferation and invasion in human cutaneous malignant melanoma. AB - Aims: MicroRNA-186 (miR-186) has been shown to be involved in various types of cancer. The purpose of this study was to investigate the expression level and functional role of miR-186 in human cutaneous malignant melanoma cells. Subjects and Methods: Expression of miR-186 was analyzed in human cutaneous malignant melanoma (CMM) cell lines SK-MEL-1, G-361, A375 and A875, and human normal epidermal melanocytes cell line HEMn-LP by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Additionally, the functional role of miR-186 on melanoma cells was investigated by transfection of miR-186 mimic followed by analyses of cell proliferation, apoptosis, and metastasis. Results: We found that the expression levels of miR-186 were decreased in CMM cell lines compared with normal epidermal melanocytes cell line. Moreover, overexpression of miR-186 inhibited cells proliferation through abrogating the G1-S transition, and reduced cells migration and invasion. Conclusions: Our findings suggested that miR-186 exhibit an inhibitory effect on CMM cell proliferation, migration, and invasion; thus, may serve as a potential therapeutic target for human CMM intervention. PMID- 29578152 TI - Death-associated protein kinase promoter methylation correlates with clinicopathological and prognostic features in nonsmall cell lung cancer patients: A cohort study. AB - Objective: The objective was to study the correlation between death-associated protein kinase (DAPK) promoter methylation and the clinicopathological and prognostic features in nonsmall cell lung cancer (NSCLC) patients. Materials and Methods: A total of 117 NSCLC patients were recruited into our study between December 2012 and December 2014. Methylation-specific polymerase chain reaction was employed to detect the methylation status of DAPK in cancer tissues, peficancerous tissues, and serum samples of 117 NSCLC patients. In addition, serum samples of 115 healthy subjects were analyzed as controls. A literature search of English and Chinese databases, based on predefined criteria, identified published studies closely related to this study. Data were extracted, and meta analysis was performed using STATA 12.0 software (STATA Corporation, College Station, TX, USA). Results: Our study results showed that DAPK promoter methylation frequency was significantly higher in NSCLC tissues compared to peficancerous normal tissues (58.1% vs. 12.8%, chi2 = 52.45, P < 0.001). When serum samples were compared, DAPK methylation frequency in NSCLC patients was higher than the control group (27.4% vs. 0, chi2 = 37.07, P < 0.001). Our meta analysis results demonstrated that DAPK methylation frequency was lower in tumor node metastasis (TNM) stage I-II compared to TNM stage III-IV (relative risk [RR] =0.87, 95% confidence interval [CI] =0.76-0.99, P = 0.041). DAPK promoter methylation frequency in NSCLC patients with lymph node metastasis was significantly higher compared to the patients with no metastases (RR = 1.26, 95% CI = 1.04-1.52, P = 0.020). Finally, the 5-year survival rate was lower in NSCLC patient group with high frequency of DAPK methylation, compared to the patient group with unmethylated DAPK (RR = 0.71, 95% CI = 0.56-0.89, P = 0.004). Conclusion: Our results showed that DAPK promoter methylation is tightly correlated with clinicopathological features of NSCLC and is associated with poor prognosis in patients. PMID- 29578153 TI - Dual-specificity phosphatase 6 genetic variants associated with risk of lung squamous cell carcinoma in Han Chinese. AB - Background: Nonsmall cell lung cancer (NSCLC) mainly contains adenocarcinoma (AC) and squamous cell carcinoma (SqCC). This study investigated single nucleotide polymorphism (SNP) of topoisomerase II alpha (TOP2A) and dual-specificity phosphatase 6 (DUSP6) in a hospital-based case and control cohort of individuals for association with risk of different histological subtypes of NSCLC. Materials and Methods: A total of 454 (237 SqCC and 217 AC) NSCLC patients, and 454 healthy controls were recruited for analysis of TOP2A rs471692 and DUSP6 rs2279574 genotypes using the TaqMan polymerase chain reaction technique. Results: TOP2A rs471692 and DUSP6 rs2279574 SNPs were in complete linkage disequilibrium; however, frequency of DUSP6 rs2279574 genotype was significantly different between the case and control, that is, DUSP6 rs2279574a/A and A/C genotypes might contribute to an increased risk of lung squamous carcinoma compared with the C/C genotype. Moreover, DUSP6 rs2279574 AA genotype was also significantly associated with advanced stages of lung cancer. In contrast, frequency of the TOP2A rs471692 genotype had no association between cases and controls (P = 0.906). Genotype frequency of DUSP6 rs2279574 was 11.9% for C/C, 43.6% for C/A, and 44.5% for A/A in the case versus 16.7% C/C, 43.4% C/A, and 39.9% A/A in the control population (chi2 = 3.136, P= 0.077 by Hardy-Weinberg equilibrium test [HWE]). The genotype frequency of TOP2A rs471692 was 50.0% for C/C, 41.6% for C/T, and 8.4% for T/T in the case versus 50.2% C/C, 43.0% C/T, and 6.8% T/T in the control populations (chi2 = 0.023, P= 0.879 by HWE test). Conclusion: Individuals are carrying DUSP6 rs2279574 AA and AC genotypes associated with an increased risk in developing lung squamous carcinoma in Han Chinese and with advanced NSCLC stages. PMID- 29578154 TI - Meta-analysis of molecular targeted agents in the treatment of elderly patients with metastatic colorectal cancer: Does the age matter? AB - Aim: Patients aged 65 years and older are often underrepresented in clinical trials of metastatic colorectal cancer (mCRC) and probably undertreated in clinical practice. We performed a meta-analysis of randomized controlled trials (RCTs) to assess the efficacy of molecular targeted agents (MTAs) in this population. Materials and Methods: A comprehensive literature search for studies published up to December 2014 was performed. The endpoints were overall survival (OS) and progression-free survival (PFS). The pooled hazard ratio (HR) and 95% confidence intervals (CIs) were calculated employing fixed- or random-effects models depending on the heterogeneity of the included trials. Results: Eleven RCTs involving 8,488 patients were ultimately identified. The pooled analysis demonstrated that the use of MTAs in elderly patients with mCRC significantly improve OS (HR 0.84, 95% CI: 0.76-0.92, P < 0.001) and PFS (HR 0.78, 95% CI: 0.64 0.96, P = 0.017) when compared to MTAs-free therapies. Similar results of OS were observed in subgroup analysis according to treatment line, therapy regimes, and approval status of MTAs. No publication bias was detected by Begg's and Egger's tests. Conclusions: The introduction of MTAs to therapies offered a survival benefit in elderly patients with mCRC. Further studies aimed at this specific patient population were still needed to watchfully monitor potential treatment related toxicities to optimize the use of these drugs. PMID- 29578155 TI - Meta-analysis of prognostic value of inflammation parameter in breast cancer. AB - Context: Recently, increasing studies investigated the association between inflammation parameter such as neutrophil to lymphocyte ratio (NLR) and the prognosis of cancers. However, the clinical and prognostic significance of NLR in breast cancer remains controversial. Aim: This meta-analysis was conducted to establish the overall accuracy of the NLR test in the diagnosis of breast cancer. Materials and Methods: A comprehensive search of the literature was conducted using PubMed and Web of Science. Six studies dating up to July 2014 with 2267 patients were enrolled in the present study. STATA 11.0 software (STATA Corporation, College Station, TX, USA) was selected for data analysis. In order to evaluate the association between NLR and overall survival (OS), disease-free survival (DFS), recurrence-free survival or cancer-specific survival, the hazard ratios (HRs), and their 95% confidence intervals (CIs) were extracted. Results: Subgroup analyses showed that NLR was a strong prognostic factor for OS in multivariate analysis (HR = 2.81, 95% CI = 2.13-3.71, PH = 0.992) and without metastasis (HR = 1.45, 95% CI = 0.37-5.66, PH < 0.001). Elevated NLR was associated with a high risk for DFS in subgroups of multivariate analysis (HR = 2.16, 95% CI = 1.67-2.80, PH = 0.977) and mixed metastasis (HR = 2.13, 95% CI = 1.38-3.30, PH = 0.84). Conclusion: In summary, NLR may be considered as a predictive factor for patients with breast cancer. PMID- 29578156 TI - Circulating gelatinases are not prognostic of treatment response and survival in locally advanced rectal cancer patients undergoing preoperative chemoradiotherapy. AB - Purpose: To investigate whether the serum levels of matrix metalloproteinases (MMPs) are predictive on treatment response and survival in locally advanced rectal cancer (LARC) patients undergoing preoperative chemoradiotherapy. Patients and Methods: Serum MMP-2 and MMP-9 was analyzed by enzyme-linked immunosorbent assay and obtained before, midway, and 1-month after the end of preoperative radiotherapy treatment. The prognostic significance of serum MMP-2 and MMP-9 levels and their association with other pathological findings for LARC patients were evaluated. Results: Serum levels of MMP-2 or MMP-9 were found to decrease with increasing clinical stage and negative correlation was statistically significant (P < 0.05). There was no statistically significant difference in tumor response and survival between the low and high MMP-2 and MMP-9 groups. MMP 2 and MMP-9 were not correlated with local-regional recurrence. Conclusions: We propose that serum levels of MMP-2 and MMP-9 are not predictive on treatment response and survival in LARC patients. PMID- 29578157 TI - miR-146a rs2910164 polymorphism and the risk of colorectal cancer in Chinese population. AB - Objective: MicroRNAs-associated single nucleotide polymorphisms are thought to play an important role in cancer development. We investigated the association of miR-146a rs2910164 polymorphism with the risk of colorectal cancer (CRC) in Chinese population. Materials and Methods: In this hospital-based case-control study of 560 cases and 780 age- and gender-matched healthy controls, the miR-146a rs2910164 polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Results: We found that miR-146a rs2910164 polymorphism was not associated with CRC risk. However, the subgroup analysis by gender showed significant associations in male subjects (GG vs. CC: Odds ratios [OR] = 1.54, 95% confidence intervals [CI] = 1.04-2.29, P = 0.03; G vs. C: OR = 1.21, 95% CI = 1.01-1.45, P = 0.04). Conclusion: Our study provides evidence that miR-146a rs2910164 polymorphism may play an important role in susceptibility to CRC in Chinese male population. PMID- 29578158 TI - Effect of spleen tyrosine kinase on nonsmall cell lung cancer. AB - Aim of Study: To investigate the anti.tumor effect of spleen tyrosine kinase. (Syk) on the human nonsmall cell lung cancer cells in vitro and its mechanism. Materials and Methods: In this study, we constructed a eukaryotic expression vector pcDNA3.1D/V5-His-TOPO/Syk and transfected it into human nonsmall cell lung cancer cells A549. Then, we not only analyzed the expression of Syk in transfected cells and its invasion but also the expression of matrix metalloproteinase-9 (MMP-9). Results: The results showed that overexpressed Syk significantly inhibited A549 cell invasive ability by decreasing the expression of MMP-9. Conclusion: The overexpressed Syk plays an important role in tumor invasion and metastasis, and a negative role in human nonsmall cell lung cancer cells. PMID- 29578159 TI - Cyclooxygenase-2 gene polymorphisms and susceptibility to hepatocellular carcinoma: A meta-analysis based on 10 case-control studies. AB - Objective: The association between cyclooxygenase-2 (COX-2) gene polymorphisms and hepatocellular carcinoma (HCC) has been widely reported, but the results are still controversial. To clarify the effect of COX-2 -1195G/A (rs689466), -765G/C (rs20417), and +8473T/C (rs5275) polymorphisms on HCC risk, a meta-analysis was performed. Materials and Methods: The PubMed, Embase, Cochrane Library, Web of Science, Chinese BioMedical Literature, Wanfang, and Chinese National Knowledge Infrastructure databases were systematically searched to identify potential studies published up to October 10, 2014. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of association. A total of eight studies with 2060 HCC cases and 2610 controls for -1195G/A, six studies with 1295 cases and 2193 controls for -765G/C, and four studies with 1477 cases and 1747 controls for +8473T/C were included in this meta-analysis. Results: Overall, the COX-2 -1195G/A, and +8473T/C polymorphisms were both significantly associated with an increased risk of HCC (rs689466 GA + AA vs. GG: OR = 1.390, P = 0.006, 95% CI: 1.099-1.759, I2 = 50.7%, Pheterogeneity = 0.048; rs5275 CC vs. TT + TC: OR = 1.484, P = 0.041, 95% CI: 1.017-2.165, I2 = 0.0%, Pheterogeneity = 0.416). In the subgroup analyses stratified by ethnicity, the COX-2 -1195G/A, 765G/C, and +8473T/C were all associated with an increased HCC risk in Asian populations (rs689466 A vs. G: OR = 1.346, P = 0.001, 95% CI: 1.137-1.595, I2 = 0.0%, Pheterogeneity = 0.869; rs20417 CC vs. GG + GC: OR = 3.069, P = 0.013, 95% CI: 1.265-7.447; rs5275 CC vs. TT + TC: OR = 1.626, P = 0.020, 95% CI: 1.079 2.452, I2 = 0.0%, Pheterogeneity = 0.495). Conclusions: Our meta-analysis suggests that -1195G/A, -765G/C, and +8473T/C in COX-2 may contribute significantly to HCC risk. PMID- 29578160 TI - Concomitant high expression of survivin and vascular endothelial growth factor-C is strongly associated with metastatic status of lymph nodes in papillary thyroid carcinoma. AB - Purpose: Papillary thyroid carcinoma (PTC) has a strong propensity to metastasize to regional lymph nodes which increases the risk of local-regional relapse and affects the course of the disease. Molecular pathogenesis of lymph node metastasis (LNM) is not yet fully understood. Survivin, a multifunctionale molecule involved in apoptosis, proliferation and angiogenesis, and vascular endothelial growth factor-C (VEGF-C) are suggested to be implicated in lymphatic metastases of human malignancies. Materials and Methods: Expression of survivin and VEGF-C was examined by immunohistochemistry and Western blot in 75 cases of PTCs in relation to their LNM status. Additionally, survivin and VEGF-C were immunohistochemically analyzed in 15 primary PTCs paired with their metastatic tissue in lymph nodes. Results: High expression of survivin and VEGF-C was found in 62.7% and 64.0% cases, respectively, with a positive correlation to each other (Spearman's correlation co-efficient = 0.878, P < 0.001). Expression levels of both proteins were significantly higher in patients with LNM than in those without LNM (P < 0.001). The rate of concomitant high expression of survivin and VEGF-C in patients with LNM involvement was 88.9% (P < 0.01). Metastatic tissue in lymph nodes expressed survivin and VEGF-C at the same high extent as their primary tumors. Conclusion: Concomitant high expression of survivin and VEGF-C is closely associated with LNM status of PTC patients, which suggests their cooperation in the metastatic process. Evaluation of survivin and VEGF-C expression could be clinically significant in predicting the metastatic potential of PTC and subsequent treatment and follow-up of these patients. PMID- 29578161 TI - Incidence of radiation enteritis in cervical cancer patients treated with definitive radiotherapy versus adjuvant radiotherapy. AB - Objective: The study aimed to evaluate the incidence of early and late radiation enteritis in cervical cancer patients receiving definitive or adjuvant radiotherapy (RT). Materials and Methods: Three hundred and twenty-four cervical cancer patients receiving definite or adjuvant RT in our hospital from January 2010 to December 2012 were divided into definitive (132 patients) or adjuvant RT (192 patients) and performed detailed analysis. Results: Early radiation enteritis was found in 54.3%, and late radiation enteritis was found in 17.9% of cervical patients. Early (P < 0.007) and late (P < 0.003) radiation enteritis appeared more frequently in patients treated with definitive RT than that with adjuvant RT. In the definitive RT group, incidence of both early and late radiation enteritis in the RT group was higher than in the radiochemotherapy (RCHT) group, and the difference was statistically significant (P < 0.004). Severe cases of late radiation enteritis (Grade 3 and 4) can be seen higher in the definitive radiation group (both the RT and RCHT group) than in the adjuvant radiation group, and the difference was statistically significant (P < 0.005). Conclusion: The incidence of both early and late radiation enteritis in the definitive RT group is higher than in the adjuvant RT group. The occurrence of side effects was associated with the prolongation of total irradiation time due to necessary interruptions of RT. Methods to decrease the interruptions in the RT and the irradiated volume of the small bowel will further lessen enteric morbidity. PMID- 29578162 TI - The autophagy induced by curcumin via MEK/ERK pathway plays an early anti leukemia role in human Philadelphia chromosome-positive acute lymphoblastic leukemia SUP-B15 cells. AB - Background: Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) is triggered by BCR/ABL tyrosine kinase which activates the downstream signaling pathways, such as Akt/mTOR, RAF/MEK/ERK, and STAT5 pathways. Curcumin has been shown to have inhibitory effects on cancers by inducing apoptosis and autophagy. We demonstrated that curcumin inhibited activation of Akt-mTOR, ABL/STAT5 pathways, inhibited cell proliferation, and induced apoptosis in Ph + ALL cells. Experiments here, were conducted to determine whether autophagy via MEK/ERK pathway involved in anti-leukemia effect of curcumin in Ph + ALL. Materials and Methods: Ph + ALL cell line SUP-B15 was treated with curcumin. Cytotoxic activity of curcumin was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl-2H-tetrazolium bromide assay. Signaling protein and specific maker of autophagy and conversion of LC3-I to LC3-II were determined by Western blot analysis. Cell apoptosis was determined by flow cytometry. Results: Curcumin treatment up-regulated the activation of RAF/MEK/ERK at 4 h and 8 h after curcumin exposure in SUP-B15 cells, curcumin treatment induced autophagy at exactly 4 h and 8 h after curcumin exposure. Curcumin exerted cytotoxic activity against SUP-B15 cells at 4 h and 8 h, which was independent of apoptosis. MEK specific inhibitor U0126 inhibited the occurrence of autophagy, and then blocked curcumin-induced cytotoxicity at 4 h and 8 h. Conclusions: Curcumin induce autophagic cell death in SUP-B15 cells via activating RAF/MEK/ERK pathway. These findings suggest that autophagic mechanism contribute to the curcumin-induced early SUP-B15 cell death, and autophagy is another anti-leukemia mechanism of curcumin. PMID- 29578163 TI - Upregulation of miR-371-373 cluster, a human embryonic stem cell specific microRNA cluster, in esophageal squamous cell carcinoma. AB - Aims: Esophageal squamous cell carcinoma (ESCC) is the most common subtype of esophageal cancer in Iran. MicroRNAs (miRNAs) are a class of noncoding RNAs that are found to be involved in different processes and can play a role in tumorigenesis and result in cancer. MiR-371, miR-372, and miR-373 are a gene cluster that is located in the region of the human chromosome of 19q13.4. They are specifically expressed in human embryonic stem cells (ESCs) and involved in the maintenance of the stemness features through regulating the expression of certain key genes and signaling pathways. The present study investigated the potential expression of miR-371-373 cluster in tumor and nontumor tissues of ESCC. Materials and Methods: The expression level of miR-371-373 cluster was analyzed in paraffin-embedded tissues of tumor and tumor margin in 36 patients with ESCC. Total RNA was isolated and the miR-371-373 clusters were quantified with quantitative real-time-polymerase chain reaction expression analysis. Computed tomography analysis (2-DeltaDeltaCT) and t-test were used to determine the relationship between the characteristics of the tumor and nontumor tissues. Statistically, P value of <0.05 were considered significant. Data analysis was performed using SPSS 16. Results: We provided miR-371, miR-372, and miR-373 upregulation evidence significantly with 14.36, 26.9, and 21.1-fold in esophageal cancer cells compared with their adjacent normal cells (P < 0.05), respectively. In addition, evaluation of these genes expression in various grades didn't show a significant difference. Conclusion: Our findings support the hypothesis that these miRNAs might play a role in tumorigenesis in esophageal cancer. PMID- 29578164 TI - Phosphatase and tensin homolog protein may be linked to lymph node metastasis and tumor node metastasis staging in nonsmall cell lung cancer. AB - Background: This study aims to investigate the correlations of positive rate of phosphatase and tensin homolog (PTEN) protein with lymph node metastasis (LNM) and tumor node metastasis (TNM) staging of nonsmall cell lung cancer (NSCLC) patients by conducted a meta-analysis. Materials and Methods: Covering several electronic databases (Embase, Cochrane Library, China BioMedicine, China National Knowledge Infrastructure, PubMed, and Web of Science), published papers eligible for enrollment in the current meta-analysis had to fulfill our predefined selection criteria. Odds ratios (ORs) with their 95% confidence interval (95%CI) were aggregated utilizing comprehensive meta-analysis 2.0 software (Biostatic Inc., Englewood, New Jersey, USA). Results: Twelve cohort studies with a total of 419 NSCLC patients were incorporated into the current meta-analysis. A decreased positive rate of PTEN protein was detected in NSCLC patients with TNM stage III IV rather than those patients with TNM stage I-II (OR = 0.454, 95%CI = 0.338 0.610, P < 0.001). PTEN in NSCLC patients without LNM expressed higher than that in the patients with LNM (OR = 0.532, 95%CI: 0.299-0.948, P = 0.032). Ethnicity stratified analysis demonstrated a negative relationship between positive rate of PTEN protein and TNM staging of NSCLC among both Asians and Caucasians (both P < 0.05). However, we found no significant association between positive rate of PTEN protein and LNM among Asians and Caucasians (both P > 0.05). Conclusion: Our findings indicate that decreased positive rate of PTEN protein may be linked to TNM staging and LNM in NSCLC, and it could be an important diagnostic biomarker of NSCLC. PMID- 29578165 TI - Predictive value of excision repair cross-complementation group 1 protein in locoregionally advanced nasopharyngeal carcinomas receiving cisplatin-based concurrent chemoradiotherapy. AB - Objective: To investigate the ability of excision repair cross-complementation group 1 (ERCC1) protein to predict cisplatin-based concurrent chemoradiotherapy (CCRT) response in locoregionally advanced nasopharyngeal carcinoma (NPC). Materials and Methods: The clinical data of 205 patients with locoregionally advanced NPC, who received cisplatin-based CCRT, were analyzed retrospectively. Immunohistochemical analysis was used to assess the ERCC1 expression in nasopharyngeal tumor tissues. Receiver operating characteristic (ROC) curve analysis, univariate and multivariate Cox proportional hazards analyses were performed to evaluate the association between ERCC1 expression and failure-free survival (FFS), overall survival (OS), locoregional-FFS (L-FFS), and distant-FFS (D-FFS). Results: Our results revealed that although the overall response rate in patients with high-ERCC1 expression (97.3%) and those with low-ERCC1 expression (100.0%) were not statistically different, but treatment-sensitive group displayed significantly lower ERCC1 expression in comparison to the treatment resistant group (P = 0.001). The Kaplan-Meier plots revealed that the low-ERCC1 expression was significantly associated with better L-FFS, FFS, and OS of locally advanced NPC patients receiving cisplatin-based CCRT. Both univariate and multivariate analysis demonstrated that the ERCC1 expression, tumor node metastasis stage and performance status were independent predictors of OS and FFS. Conclusion: ERCC1 expression may be a useful predictive marker in patients with locoregionally advanced NPC, who are receiving cisplatin-based CCRT. PMID- 29578166 TI - The effect of temperature-control microwave on HELA and MG-63 cells. AB - Context: Hyperthermia has now been used to treat many kinds of solid malignancies. However, the applied thermal parameters about heat temperature and time varied all over the world, and no consensus about the optimal formula had been reached. Microwave ablation, as one of thermal ablation methods, is usually applied based on the fixed parameters of power and duration. As a result, too high temperature or overheating might not be avoided and excessive heating might cause some additional side effects to normal tissues. Aims: To explore the optimal parameters of power and duration for the HELA and MG-63 cells in vitro. Settings and Design: With a temperature-controlled microwave workstation, a microwave thermal ablation experiment was performed in vitro. Subjects and Methods: The HELA and MG-63 cells were heated with 40 degrees C, 45 degrees C, 50 degrees C, 55 degrees C, and 60 degrees C lasting for 5-30 min, respectively. Then, the cell viability was detected using four methods: Flow cytometer assay, nicotinamide adenine dinucleotide-diaphorase staining, Calcein-acetoxymethyl ester staining immediately after treatment, and CCK-8 assay 24 h later. Results: The temperature-controlled microwave has an excellent ablation effect on both cell lines. Furthermore, when the thermal stimulation reached 55 degrees C 25 min and 55 degrees C 20 min for the HELA and MG-63 cells, respectively, or 60 degrees C 5 min for both, all the viability indexes indicated immediately devitalization. Conclusion: It presented a preliminary minimum lethal dose of heat was validated on the cellular level in vitro, which should be verified and corrected further in vivo. PMID- 29578167 TI - Overexpression of S100A4 protein may be associated with the development and progression of pancreatic cancer. AB - Aim: Accumulated evidence has suggested a relationship between S100A4 protein expression and the development and progression of pancreatic cancer (PC) while its role in diagnosis and prognosis of PC still keeps inconsistent. To obtain definitive associations between S100A4 and PC, a meta-analysis was conducted. Materials and Methods: The PubMed and Chinese National Knowledge Infrastructure databases were electronically searched to identify studies reporting an association between S100A4 protein and PC. Statistical analyses were undergone with the utilization of STATA version 12.0 software. Results: Nine clinical studies with a total of 545 tumor samples were included in the meta-analysis. Results revealed that increased S100A4 expression were associated with the tumor node-metastasis stages of PC (III-IV vs. I-II: odds ratio [OR] =5.50, 95% confidence interval [95% CI] =3.13-9.67, P < 0.001). Also, compared with 1-2 histologic grade of PC samples, S100A4 protein was expressed more frequently in samples with 3-4 histologic grade (grades 1-2 vs. grades 3-4: OR = 2.57, 95% CI = 1.05-6.24, P = 0.038). Conclusion: This meta-analysis showed that overexpression of S100A4 seems to be associated with tumor progression and poor prognosis of PC patients. PMID- 29578168 TI - Short-term outcomes after transition from Sweet to thoracoscopic esophagectomy: Our experience and cost analysis. AB - Objective: Thoracoscopic esophagectomy (TSE), as a minimally invasive technique, has obtained wide acceptance for treating esophageal cancer. In this study, we report our experience of the transfer from open sweet esophagectomy (OSE) to TSE and compare cost associated with the two approaches for esophageal cancer. Patients and Methods: Data were taken through a retrospective review of operative outcomes, complications and cost of 91 patients who underwent OSE or TSE for esophageal cancer from January 2012 to June 2014. Results: Among 91 patients, 48 patients underwent TSE, and 43 patients underwent OSE. Patients dealt with TSE had significantly less blood loss (152 ml vs. 204 ml, P = 0.004), shorter chest drainage time (3.3 days vs. 4.5 days, P < 0.001), less patients admitted to the Intensive Care Unit after surgery (6.3% vs. 30.2%, P = 0.003), and lower incidence of respiratory complications (16.7% vs. 37.2%, P = 0.026). However, the operative time was statistically longer in TSE group (276.0 min vs. 207.4 min, P < 0.001). The total cost (Y61,817 vs. Y48,712, P < 0.001) and the day of surgery cost (Y29,701 vs. Y19,446, P < 0.001) were significantly higher in the TSE group. Conclusion: This study shows that TSE is a safe and acceptable alternative to OSE. TSE will be more competitive if its cost can be reduced. PMID- 29578170 TI - Association of toll-like receptors with the risk of oral squamous cell carcinoma. AB - Aim of Study: Association of toll-like receptors (TLRs) with the risk of oral squamous cell carcinoma (OSCC) from the published reports is still conflicting. This study was conducted to evaluate the relationship between TLRs and the risk of OSCC using meta-analysis method. Materials and Methods: The association studies were identified from PubMed and Cochrane Library on April 01 2015, and eligible investigations were included and synthesized using meta-analysis method. Result: Three reports were recruited into this meta-analysis for the association of TLRs with OSCC susceptibility. In this meta-analysis, we found that TLRs were not associated with OSCC susceptibility. However, in the sub-group analysis, we found that TLR-7 was associated with OSCC risk. Conclusion: TLR-7 was associated with OSCC risk. TLR-7 might be an indicator to predict the OSCC risk. However, more studies should be conducted to confirm it. PMID- 29578169 TI - Clinical research of goal-directed fluid therapy in elderly patients with radical resection of bladder cancer. AB - Objective: The aim of this study is to investigate the clinical effect of goal directed fluid therapy in elderly patients with radical resection of bladder cancer. Materials and Methods: Seventy-six elderly patients with radical resection of bladder cancer were selected from October 2012 to October 2014 and randomly divided into two groups, in which 38 patients received routine treatment as the control group and 38 patients received goal-directed fluid therapy based on routine treatment as the observation group. The treatment effect was compared between two groups. Results: The cardiac index, stroke volume variability, mean arterial pressure, central venous pressure, central venous oxygen saturation, oxygen supply index, oxygen consumption index, and oxygen uptake rate in observation group were distinctly higher than those in control group at T1, T2, T3, and T4 while the artery serum lactate and S100-beta were apparently lower than those in control group at T1, T2, T3, and T4. The urine volume and colloidal infusion were obviously elevated when compared with those in control group at T1, T2, T3, and T4 while the crystalloid infusion volume, total liquid infusion volume, hospitalization time, and expenses were significantly less than those in control group; further, similar tendency was also found regarding the complication incidences of nausea, vomiting, or hypotension in observation group. The postoperative flatus and postoperative food-taking times were visibly earlier than those in control group (both P < 0.05). Conclusion: The goal-directed fluid therapy is beneficial for stabilization of hemodynamic status and maintenance of oxygen balance of supply and demand, and it is worthy of clinical expansion for good microcirculation perfusion, reduction in therapeutic time and expenses of patients, and less complications and superior security. PMID- 29578171 TI - Effect of smoking on high-grade cervical cancer in women on the basis of human papillomavirus infection studies. AB - Purpose: We aimed, in the present study, to measure the risk related to the high grade cervical intraepithelial neoplasia grade 3 (CIN3) or worse (CIN3+) or worse/high-grade squamous intraepithelial lesions with respect to changes in human papillomavirus (HPV) and smoking status. Materials and Methods: A structured interview underwent for 7129 women. Then, we obtained their cervical cells and subjected to HPV testing. High-risk HPV infected and "no prevalent" cervical disease infected women were followed for cervical lesions up to 12 years (at baseline; n = 1531). Hazard ratios (HRs) for diagnosis of CIN3 (or worse) or worse/high-grade intraepithelial lesions were calculated along with the corresponding 95% confidence intervals (CIs). Results: Among high-risk HPV positive women, the conditions of long-term (more than 8 years) smokers and heavy (18 or more cigarettes/day) smokers are highly responsible for the increased risk for CIN3 or CIN3+. In the cases of persistent HPV-infected women, heavy smoking led to a higher risk for CIN3+ than those women who never smoked (HR, 2.31; 95% CI, 1.12-4.16). Conclusion: We concluded here that smoking leads to an enhanced risk of high-grade cervical lesions in persistent high-risk HPV-infected women. This makes a good understanding of smoking's role in cervical cancer. PMID- 29578172 TI - Effect of bevacizumab combined with chemotherapy at different sequences in the gastric-cancer-bearing nude mice. AB - Objective: To observe changes in the growth of fluorescence-labelled tumour cells in nude mice using small animal in vivo imaging technology and to compare the anti-tumour effects of the administration of bevacizumab monoclonal antibodies combined with chemotherapy at different time sequences. Materials and Methods: Different time sequences of administration of bevacizumab monoclonal antibodies combined with the 5-fluorouracil and cisplatin (FP) chemotherapy regimen were used for intervention treatment of tumour growth in a subcutaneous xenograft model of human gastric cancer in nude mice. Tumour growth, that is, tumour volume, was evaluated with the changes in fluorescence signal strength and the inhibition rate. Results: Compared with the control group (normal saline), experimental groups had a certain inhibition rate, while the tumour inhibition rate in the group with a bevacizumab treatment for 24 h followed by the FP chemotherapy regimen was the highest (68.42%). Moreover, the fluorescence signal strength changed significantly in all of the experimental groups. At the 3rd week of bevacizumab administration, the fluorescence signal value in the group with a bevacizumab treatment for 24 h followed by the FP chemotherapy regimen was the lowest, indicating this is the best treatment out of five groups. Conclusion: Bevacizumab monoclonal antibodies combined with chemotherapy had synergistic effects. The small animal in vivo imaging system could dynamically obtain long and short diameters of tumours and their fluorescence signal values; compared with traditional methods that calculate tumour inhibition rates by weighing tumours, this method was more sensitive and more objective for drug evaluation. PMID- 29578173 TI - Guiding values of multislice spiral computed tomography angiography in laparoscopic D2 radical gastrectomy of local advanced gastric carcinoma. AB - Objective: This study aims to investigate the application values of preoperative multislice spiral computed tomography angiography (MSCTA) in laparoscopic radical resection of gastric carcinoma (GC). Materials and Methods: A total of 108 GC patients were divided into Groups I (i.e., where preoperative MSCTA was performed; n = 60) and II (i.e., where preoperative MSCTA was not performed; n = 48). Surgery was performed by the same group of surgeons. Results: Seven cases of blood vascular variation were detected in Group I during surgery, whereas four cases were detected in Group II. The operation time for Group I ([207 +/- 24] min) was shorter than that for Group II ([260 +/- 31] min) (95% confidence interval [95% CI]: -21.543--0.920, P = 0.044). The operation time of patients with gastric vascular anatomic variation in Group I ([189 +/- 49] min) was shorter than that of patients in Group II ([257 +/- 61] min) (95% CI: -99.68- 3.201, P = 0.048). The differences in the number of lymph node dissection, average blood loss, eating time, complication rate, and postoperative hospital stay between the two groups was not statistically significant (P > 0.05). Conclusions: MSCTA before endoscopic radical resection exhibits guiding values in assessing blood vascular variations and shortening operation times. PMID- 29578174 TI - Effects of continued psychological care toward brain tumor patients and their family members' negative emotions. AB - Purpose: Numerous studies have confirmed that brain tumor patients and their family members frequently exhibit negative emotional reactions, such as anxiety and depression, during diagnosis and treatment of the disease. Family members experience increasing pressure as the year of survival of patient progress. The aim of this study was to investigate the effects of the continued psychological care (CPC) toward the brain tumor patients and their family members' emotions. Subjects and Methods: The asynchronous clinical control trial was performed, and 162 brain tumor patients and their family members were divided into the control group and the intervention group. The control group was only performed the telephone follow-up toward the patients. Beside this way, the intervention group was performed the CPC toward the patients and their family member. The self rating anxiety scale (SAS) and the self-rating depression scale (SDS) were used to measure the negative emotions of the patients and their family members, and the patients' treatment compliance and the incidence of seizures were compared. Results: The SAS and SDS scores of the intervention group on the 14 days, 28 days and 3 months of the CPC were significantly lower than the control group (P < 0.05); the SAS and SDS scores of the intervention group after the intervention were significantly lower than those at the discharging (P < 0.05), the treatment compliance of the intervention group was significantly higher than the control group (P < 0.05), and the seizure incidence of the intervention group was significantly lower than the control group (P < 0.05). Conclusion: The CPC could effectively reduce the anxiety and depression among the brain tumor patients and their family members. PMID- 29578175 TI - TOX high mobility group box family member 3 rs3803662 and breast cancer risk: A meta-analysis. AB - Aims: Some studies suggested that TOX high mobility group box family member 3 (TOX3) rs3803662 polymorphism was associated with the risk of breast cancer. However, the results were controversy. Therefore, in order to derive a more comprehensive estimation of the association between TOX3 rs3803662 polymorphism and breast cancer risk, we conducted a meta-analysis to investigate this relationship. Materials and Methods: An electronic literature search was conducted using the following database: PubMed, EMBASE, and China National Knowledge Infrastructure till to March 31, 2015. The strength of the associations between the TOX3 rs3803662 polymorphism and breast cancer risk in per alle model was measured by odds ratios (ORs) and 95% confidence intervals (CIs). Results: A statistically significant association between TOX3 rs3803662 polymorphism and breast cancer risk was fond. The data showed that TOX3 rs3803662 polymorphism could increase the risk of breast cancer (OR = 1.20; 95% CI: 1.16-1.25; P < 0.00001). In the subgroup analysis of race, Caucasians, Asians, and Hispanics also showed increased breast cancer risk (OR = 1.21; 95% CI: 1.17-1.25; P < 0.00001; OR = 1.20; 95% CI: 1.08-1.33; P = 0.0004; OR = 1.32; 95% CI: 1.12-1.57; P = 0.001). However, African-Americans with TOX3 rs3803662 polymorphism showed decreased breast cancer risk (OR = 0.95; 95% CI: 0.86-1.04; P = 0.28), although the result was not significant. When considered estrogen receptor (ER) status, we found that ER + subjects and ER - subjects all had increased breast cancer risk, if they carried this polymorphism (OR = 1.27; 95% CI: 1.19-1.35; P < 0.00001; OR = 1.12; 95%CI: 1.08-1.17; P < 0.00001). Similarly, both progesterone receptor positive (PR +) subjects and PR - subjects all showed increased breast cancer risk, if they carried this polymorphism (OR = 1.32; 95% CI: 1.17-1.49; P < 0.00001; OR = 1.15; 95% CI: 1.09-1.23; P < 0.00001). Conclusions: This meta analysis suggested that TOX3 rs3803662 polymorphism was associated with increased breast cancer risk. PMID- 29578176 TI - Applications of nerve stimulator-guided thoracic paravertebral nerve block plus general anesthesia in small-incision lung cancer surgery. AB - Objective: The aim of the study was to investigate the application of nerve stimulator-guided thoracic paravertebral nerve block (TPVB) plus general anesthesia (GA) in small-incision lung cancer surgery. Methods: Forty patients scheduled for small-incision lung cancer surgery, the American Society of Anesthesiologists Grade I-II, were randomized into a TPVB-GA group (Group P) and a GA group (Group G), with 20 cases in each group. The dosage of general anesthetic, mean arterial pressure (MAP) at each time point, and heart rate (HR) of the two groups were recorded. The postoperative respiration recovery time, extubation time, incidence of adverse reactions, and postoperative visual analog scale (VAS) scores of the two groups were also observed. Results: Group P showed stable hemodynamics, and lower MAP and HR at each time point than Group G (P < 0.05). The intraoperative dosage of general anesthetic in Group P was lower than that in Group G (P < 0.05). The respiration recovery time and extubation time in Group P were significantly shorter than those in Group G (P < 0.05); the incidence of agitation was significantly lower than that in Group G (P < 0.05). The VAS scores of Group P under quiet and cough status were also better than Group G (P < 0.05). Conclusions: Nerve stimulator-guided TPVB-GA is suitable for small-incision lung cancer surgery. PMID- 29578177 TI - The clinical benefit of epidermal growth factor receptor and human epidermal growth factor receptor 2 targeted agents adding to endocrine therapy in hormone receptor-positive breast cancer. AB - Objectives: Studies have suggested that the crosstalk between estrogen receptor and ErbB receptor is involved in endocrine therapy (ET) resistance, which might be overcome by drugs-targeting ErbB receptor. However, the results of clinical studies remain controversial. The aim of this meta-analysis was to evaluate the efficacy and safety of ErbB (mainly epidermal growth factor receptor and human epidermal growth factor receptor 2 [HER2]) inhibitors added to ET for hormone receptor-positive breast cancer patients. Materials and Methods: Eligible randomized clinical trials on ET with or without ErbB receptor-targeting inhibitors (ERTI) for hormone receptor-positive breast cancer were identified by searching the main electronic databases (up to July 2015). Revman 5.3 was used to analyze the outcomes extracted from the included trials. Results: In the overall population, ERTI failed to show any significant differences on overall response rate (ORR), clinical benefit rate (CBR), and overall survival (OS). However, improvement on progression-free survival (PFS) (hazard ratio [HR] 0.84, 95% confidence interval [CI] = 0.76-0.93, P = 0.0005) was observed. For the HER2+ subgroup, ERTI could significantly improve ORR, CBR, PFS, OS, and time to progression compared to endocrine monotherapy. This improvement cannot be found in the HER2- subgroup. The risk of serious adverse events (SAEs) increased significantly when ERTI was present (RR = 2.09, 95% CI = 1.44-3.02, P < 0.0001). Conclusions: For HR+/HER2+ breast cancer, ERTI added to ET can significantly improve the clinical efficacy with the cost of increasing SAE. PMID- 29578178 TI - Comparison of short-course with long-course preoperative neoadjuvant therapy for rectal cancer: A meta-analysis. AB - Aim: This study attempted to compare the prognostic performance of short- and long-course preoperative treatments for neoadjuvant therapy of rectal cancer by meta-analysis. Methods: Electronic databases of PubMed and Embase were searched for eligible studies updated to February 29, 2016. Studies were included based on several predefined inclusion criteria. Quality assessment was carried out according to the Cochrane Collaboration recommendations in Cochrane handbook. Outcomes such as 1-5 survival rates, death rate, recurrence rate, complication rate, and distant metastasis were evaluated. Odds ratio (OR) with the corresponding 95% confidence interval (CI) was used to calculate the pooled results. Subgroup analysis stratified by radiotherapy (RT) and chemoradiotherapy (CRT) was performed. Publication bias was detected based on Egger's test. Sensitive analysis was also performed. Results: Eight studies were included, and they were randomized controlled trials or controlled clinical trials. The included studies involved a total of 1475 patients (short treatment: n = 665; long treatment: n = 810). No significant difference was detected in each outcome between the short- and long-course preoperative treatments. Subgroup analysis indicated that the outcome of distant metastasis was significantly higher in long course RT, compared with the short-course RT (OR = 2.65, 95% CI: 1.05, 6.68). No significant publication bias was observed. Sensitive analysis did not show any reverse result. Conclusion: Short- and long-course preoperative treatments seem comparable for management of rectal cancer, in terms of outcomes such as survival, recurrence, and complications. However, long-course RT might increase risk of distance metastasis, compared to short-course RT. PMID- 29578179 TI - Solanum nigrum polysaccharide inhibits tumor growth in H22-bearing mice through regulation of caspase-3 and bcl-2. AB - Objective: The objective of this study was to investigate the effect of Solanum nigrum polysaccharides (SNPs) on tumor growth in H22 hepatocarcinoma cells bearing mice and explore the mechanism by focusing on the regulation of the expression of caspase-3 and bcl-2. Materials and Methods: Totally, 50 mice bearing with H22 cells were randomly divided into five groups: Model group, cyclophosphamide group (CTX, 30 mg/kg), SNP groups with low, medium, and high doses of SNP (30, 60, and 120 mg/kg). Twenty-four hours after inoculation of H22 cells, CTX or SNP were given by gavage once a day for 10 days. The growth of tumor was observed. The tumor inhibition rate, indexes of the spleen and thymus were calculated. The immunohistochemical method was used for the determination of caspase-3 and bcl-2 expression in the tumor tissue. Results: SNP (30, 60, and 120 mg/kg) reduced the average tumor weight compared with that in model group in a dose-dependent manner, and the tumor inhibition rates were 37.73%, 38.24%, and 42.60%, respectively. In addition, SNP dose dependently increased the index of the thymus compared with that of the CTX group. Immunohistochemistry results showed that the protein expression of caspase-3 in SNP groups was higher, but the expression of bcl-2 was lower than that in model group in a dose-dependent manner. Conclusion: SNP inhibited the growth of tumor in H22-bearing mice and protected the immune organ. The mechanism underlying the inhibition of tumor might be related to the upregulation of caspase-3 and downregulation of bcl-2. PMID- 29578180 TI - Effect of lenalidomide on the human gastric cancer cell line SGC7901/vincristine Notch signaling. AB - Aim of Study: To examine the function of lenalidomide (LEN) on the human multidrug resistance (MDR)-type gastric cancer line SGC7901/vincristine (VCR) via regulating Notch signaling. Materials and Methods: Quantitative polymerase chain reaction was used for checking the genes of Notch, DNA methyltransferase (DNMT), RBP-J, Hes1/5, Deltex1, MDR/multidrug resistant protein (MRP); the cell proliferation and cell death were detected by cell counting kit-8 (CCK8) staining, Ki-67 expression, and propidium-iodide staining, and methylated DNA immunoprecipitation assay (MeDIP) was used for checking the 5 mC enrichment, indicating the DNA methylation of the Notch2 gene loci. Results: LEN reduced the mRNA expression of Notch2 (P < 0.01) and increased the expression of the DNMT3A (P < 0.001) in SGC7901/VCR cell, suggesting the involvement of epigenetic regulation by DNMT3A on Notch2 gene expression. Consistently, Notch2 gene expression showed no obvious change between the LEN treatment and the control when the DNMT3A was knockdown using the interference of shRNA. The modulation of DNA methylation process on gene expression was then confirmed by 5 mC enrichment on Notch2 gene loci after LEN treatment. Furthermore, LEN could suppress the downstream genes in Notch2 signaling including RBP-J (P < 0.05), Hes1 (P < 0.001), and Deltex1 (P < 0.01). Due to the changes of gene expression pattern in Notch pathway, LEN showed a phenotype of cell proliferation suppression using CCK8 staining. Meanwhile, the expression of the genes associated with MDR and MRP was also significantly decreased (MDR, P < 0.01; MRP, P < 0.001) after LEN treatment. Therefore, inhibition of cell proliferation by LEN via Notch2 signaling combined with the MDR/MRP expression modulation contributes to the efficacy of LEN on the gastric cancer cell line SGC7901/VCR. Conclusion: The data implicate that LEN would be an effective chemical for the therapy of drug resistant human gastric cancer cell and the gastric cancer patients. PMID- 29578181 TI - Identification of key genes related to high-risk gastrointestinal stromal tumors using bioinformatics analysis. AB - Aim: The purpose of this study was to identify predictive biomarkers used for clinical therapy and prognostic evaluation of high-risk gastrointestinal stromal tumors (GISTs). Materials and Methods: In this study, microarray data GSE31802 were used to identify differentially expressed genes (DEGs) between high-risk GISTs and low-risk GISTs. Then, enrichment analysis of DEGs was conducted based on the gene ontology and kyoto encyclopedia of genes and genomes pathway database. In addition, the transcription factors and cancer-related genes in DEGs were screened according to the TRANSFAC, TSGene, and TAG database. Finally, protein-protein interaction (PPI) network was constructed and analyzed to look for critical genes involved in high-risk GISTs. Results: A total of forty DEGs were obtained and these genes were mainly involved in four pathways, including melanogenesis, neuroactive ligand-receptor interaction, malaria, and hematopoietic cell lineage. The enriched biological processes were related to the regulation of insulin secretion, integrin activation, and neuropeptide signaling pathway. Transcription factor analysis of DEGs indicated that POU domain, class 2, associating factor 1 (POU2AF1) was significantly downregulated in high-risk GISTs. By constructing the PPI network of DEGs, ten genes with high degrees formed local networks, such as PNOC, P2RY14, and SELP. Conclusions: Four genes as POU2AF1, PNOC, P2RY14, and SELP might be used as biomarkers for prognosis of high risk GISTs. PMID- 29578182 TI - Diffuse large B-cell lymphoma with concurrent hepatitis B virus infection in the MabThera era: Unique clinical features and worse outcomes. AB - Aim of Study: Hepatitis B virus (HBV) infection is a risk factor in diffuse large B-cell lymphoma (DLBCL); however, little is known other than the prevalence evidence. In addition, the impact of HBV infection to DLBCL remains controversial. The purpose of this study was to investigate the HBV infection status of 136 patients with DLBCL, analyze the clinical property of HBV-infected patients, and determine the effects of HBV infection to the outcomes of DLBCL patients. Materials and Methods: A retrospective analysis was performed in our center from January 2007 to December 2014. A total of 136 DLBCL patients accepting three or more cycles of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) regimen were analyzed. Results: Of the 136 patients, 55 were HBV-infected and their clinical features were different in several aspects such as young onset age (P = 0.027), frequent occurrence of B symptom (P = 0.009), and advanced disease stage (Stage III/IV, P = 0.037). Besides more HBV infected patients exhibited lower levels of peripheral lymphocyte-to-monocyte ratio (<=2.0). In the survival assessment, HBV-infected patients were worse in both progression-free survival (PFS) (P = 0.001) and overall survival (OS) (P = 0.030) in MabThera treated group, but get a draw in CHOP regimen group (P = 0.658 in PFS and P = 0.798 in OS). Sort of surprisingly, HBV-infected patients treated with MabThera did not have a superior to the traditional regimen in both PFS (P = 0.969) and OS (P = 0.875). Conclusion: DLBCL patients with HBV infection are subset with unique clinical characters and have worse outcomes. The benefit of MabThera to HBV-infected DLBCL patients was uncertain thus have to be weighed against the costs before application. PMID- 29578183 TI - Four case reports on pelvic tumors with deep venous thromboses as main symptoms and literature review. AB - To probe into the reasons for misdiagnoses of pelvic tumor as deep venous thromboses as well as the diagnostic methods and effective treatments on pelvic tumor. Four case reports on misdiagnosing pelvic tumor as deep venous thromboses and further analysis on the causes of misdiagnosis, diagnosis, and treatment with the literature study. The four cases were misdiagnosed as pelvic tumor, which actually were fibroneuroma, myxo.fluidity liposarcoma, moderately differentiated squamous cell carcinoma, and synovial sarcoma, respectively. The tumor in first case was completely removed, and the tumor in other three cases, which were malignant tumors, were resected when the tumors shrank with clear boundary and less blood supply after applied with 3. cycles of intra.arterial chemotherapy via an implanted pumpies. Pelvic tumor usually show up or is misdiagnosed as deep venous thromboses for its untypical clinical manifestation, so it should be on the alert for pelvic tumor when deep venous thromboses occurs. Tumor resection is preferred for benign tumor, and intra.arterial intervention chemotherapy should be applied first for malignant tumor followed by surgery. PMID- 29578184 TI - Uterine metastases originating from a pulmonary inflammatory myofibroblastic tumor. AB - Pulmonary inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor, and is considered an inflammatory pseudotumor. Here, we report of a 37-year-old woman with severe cough and stridor who was diagnosed with primary IMT of the lungs, with adenocarcinoma in situ based on the pathology in December 2012. A year later, transabdominal ultrasonography demonstrated a solid mass in the uterine wall that was initially diagnosed as a leiomyoma. However, postoperative histological examination and immunohistochemical staining revealed it as a uterine metastasis of the lung IMT. One year thereafter, the patient died of the lung tumor. PMID- 29578185 TI - Hypofractionated postoperative irradiation in localized renal cell cancer: A case report and pertinent literature review. AB - For localized the incidence of renal cell carcinoma (RCC), nephrectomy is the standard treatment. As RCC is generally regarded as a radiation-resistant tumor, the value of postoperative adjuvant radiotherapy is controversial. However, with new advance in radiotherapy (i.e., three-dimensional conformal radiation therapy [3DCRT] and intensity-modulated radiation therapy [IMRT]), target volume delineation, intensity modulation in treatment planning, and treatment delivery are more accurate with fewer adverse effect. A right renal tumor was identified in a 50-year-old man during a routine examination. T1N0M0 RCC was clinically diagnosed as the tumor was 3 cm * 3.5 cm and well-enhanced with intravenously infused contrast material in the arterial phase on computed tomography (CT). No metastases to regional lymph nodes or distant sites were evident. 3DCRT after the operation was carried out. A total dose of 50 Gy in 20 fractions over 28 days was delivered using a 15-MV X-ray. No clinical acute or chronic side effects were recorded during or after treatment, which was well tolerated. After radiotherapy, the patient came back to the hospital for a check regularly, with no evidence of recurrence and metastasis more than 11 years, and the CT for abdominal showed partial function of the right renal remained. The present case showed a good response with recovery after CRT of 50 Gy in 20 fractions for postoperative RCC. Although further experiences and longer follow-up are mandatory to conclude the optimal treatment schedule and efficacy of CRT for RCC, postoperative radiotherapy definitely reduces locoregional recurrences and with acceptable gastrointestinal toxicity if modern techniques (CRT and IMRT) are utilized. PMID- 29578186 TI - Contrast-enhanced ultrasound imaging characteristics of malignant transformation of a localized type gallbladder adenomyomatosis: A case report and literature review. AB - Gallbladder adenomyomatosis (GAM) is an acquired, reactive, tumor-like condition. Malignant transformation is extremely rare, and imaging features during contrast enhanced ultrasound (CEUS) have not been described before. Herein, we describe a 73-year-old Asian man who had been diagnosed with gallbladder carcinoma by conventional ultrasonography (US). Based on additional radiological findings, we believed that it was a localized adenomyomatosis. However, the histopathological diagnosis was adenocarcinoma originate from adenomyomatosis with serosal invasion. We believe this is the first case of adenocarcinoma derived from GAM with characteristics of CEUS findings. This case is presented to indicate a clinical awareness of malignant transformation of GAM and discuss the radiology significance with an emphasis on CEUS. PMID- 29578187 TI - Primary renal synovial sarcoma: A case report and literature review. AB - Synovial sarcomas (SSs) are very rare, poorly studied tumors that generally occurs around joint and muscle tendons. Primary SSs of the kidney are even rarer, accounting for <2% of all malignant renal tumors. We report the case of a 44-year old man who was diagnosed with primary renal SS on the basis of imaging, histopathological, and immunohistochemical examination. We also present a comprehensive review of the literature, with a focus on the differential diagnosis and treatment of renal tumors. PMID- 29578188 TI - Spectrum of hyperosmolar hyperglycaemic state in neurology practice. AB - Background & objectives: Hyperosmolar hyperglycaemic state (HHS) is a medical emergency, but there is a paucity of studies reporting the spectrum of neurological manifestations of HHS. We, therefore, report the neurological spectrum, triggering factors and outcome of HHS in general neurology practice. Methods: The records of the patients with HHS were extracted from computerized hospital information system and those managed currently were prospectively included. The demographic, clinical manifestations, duration of diabetes and precipitating events such as infection, stress and stroke were noted. Patients with HHS were categorized into seizure, movement disorder and encephalopathy groups. Their electroencephalography, magnetic resonance imaging (MRI) findings and outcome were noted. Results: There were 17 patients with HHS (age range 40 and 75 yr) and seven were females. Seven patients were diabetic for five years, one for four years, one for one year and four were diagnosed after the occurrence of HHS. Four patients had epilepsia partialis continua persisting for 72-360 h, one patient had focal seizures and his MRI revealed T2 hyperintensity in frontal region in one patient and cerebellar vermian hyperintensity in another. All the five patients improved, but two had neurological deficits on discharge. Nine patients had encephalopathy which was precipitated by stroke in six patients, urinary infections in two and meningitis in one. Three females had hemichorea hemiballismus syndrome, which was triggered by infections. Abnormal movements lasted 5-10 days and responded to correction of hyperosmolarity. Nine out of 17 patients improved completely whereas the remaining eight had partial recovery, these patients had stroke, ventilator-related complications or meningoencephalitis. Interpretation & conclusions: The most common presentation of HHS was encephalopathy (9) followed by seizure (5) and hemichorea hemiballismus syndrome (3) which responded to the correction of hyperosmolar state. PMID- 29578189 TI - Effect of multilevel lower-limb botulinum injections & intensive physical therapy on children with cerebral palsy. AB - Background & objectives: Botulinum toxin is considered as an effective treatment for spasticity in children with cerebral palsy (CP). However, there are only a few long-term studies, and the effects on motor function have been inconclusive. Moreover, due to its high cost and need for intensive post-injection therapy, utility in context of developing nations has not been established. This retrospective study was undertaken to assess the long term effects of botulinum toxin-A with physical therapy in children with CP. Methods: This retrospective study was conducted at a tertiary care centre in India, where a limited supply of botulinum toxin was introduced in the year 2009. It was used in a selective group of patients with CP along with intensive physical therapies. All children who received lower-limb botulinum injections over a 42-month period were analyzed. For evaluation of treatment effect, the measurement at 1st pre-injection assessment and the last measurements, i.e. 12 wk after last injection received by that child were compared. Results: Twenty nine patients (20 males, median age 51 months) received 69 sessions of botulinum toxin injections in the lower limbs over a 42-month period. Thirteen patients were diplegic, 10 were quadriplegic, five were triplegic and one was hemiplegic. There was a significant improvement in pre- and post-injection scores on Observational Gait Scale (right side 7.1+/ 3.6 to 10.7+/-3.7, left side 6.7+/-3.5 to 9.9+/-3.4), Gross Motor Function Measure Scale (47.9+/-17.7 to 67.6+/-17.2), Modified Ashworth Scale, passive range of motion and Gross Motor Function Classification System. Most of the patients showed gain in motor milestones as well. Interpretation & conclusions: Our results showed that judicious use of botulinum injections along with intensive physio/occupational therapies could yield good results in children with CP. PMID- 29578190 TI - Uromodulin rs4293393 T>C variation is associated with kidney disease in patients with type 2 diabetes. AB - Background & objectives: Uromodulin, a UMOD gene encoded glycoprotein is synthesized exclusively in renal tubular cells and released into urine. Mutations lead to uromodulin misfolding and retention in the kidney, where it might stimulate cells of immune system to cause inflammation and progression of kidney disease. Genome-wide association studies (GWAS) have identified UMOD locus to be associated with hypertension and diabetic nephropathy (DN). In this study, we investigated the association between rs4293393 variation in UMOD gene and susceptibility to kidney disease in individuals with type 2 diabetes mellitus (T2DM). Methods: A total of 646 individuals, 208 with T2DM without evidence of kidney disease (DM), 221 with DN and 217 healthy controls (HC) were genotyped for UMOD variant rs4293393T>C by restriction fragment length polymorphism. Serum uromodulin levels were quantified by enzyme-linked immunosorbent assay. Results: A significant difference was found in genotype and allelic frequency among DM, DN and HC. TC+CC genotype and C allele were found more frequently in DN compared to HC (33.9 vs 23.0%, P=0.011 and 20.1 vs 12.9%, P=0.004, respectively). Compared to DM, C allele was found to be more frequent in individuals with DN (20.1 vs 14.7%, P=0.034). Those with DN had higher serum uromodulin levels compared to those with DM (P=0.001). Serum uromodulin levels showed a positive correlation with serum creatinine (r=0.431; P<0.001) and negative correlation with estimated glomerular filtration rate (r=-0.423; P<0.001). Interpretation & conclusions: The frequency of UMOD rs4293393 variant with C allele was significantly higher in individuals with DN. UMOD rs4293393 T>C variation might have a bearing on susceptibility to nephropathy in north Indian individuals with type 2 diabetes. PMID- 29578191 TI - Unenhanced renal magnetic resonance angiography in patients with chronic kidney disease & suspected renovascular hypertension: Can it affect patient management? AB - Background & objectives: Renal artery stenosis (RAS) is an important cause of severe hypertension in patients with chronic kidney disease (CKD). It is important to detect RAS early as it can reverse hypertension and stop rapid deterioration of renal function. The potential drawbacks of various imaging modalities used to detect RAS including contrast-related adverse effects associated with diagnostic angiography have led to increasing interest in unenhanced magnetic resonance (MR) renal angiography. The aim of this study was to detect and grade RAS in patients with CKD and suspected renovascular hypertension using unenhanced MR angiography (UMRA) and to identify patients with significant RAS (>70%) who would subsequently require further investigation and revascularization. Methods: Thirty five CKD patients with suspected RAS were subjected to UMRA using non-contrast MR angiography of ArTery and VEins 3D True fast imaging with steady state precession technique over a three year period. Patients with RAS >70 per cent on UMRA were subjected to digital subtraction angiography (DSA) with intervention if indicated. Results: In all, 76 renal arteries were evaluated using UMRA in 35 patients, of which 18 arteries showed stenosis and 11 were haemodynamically significant (eight patients). Seven patients (10 renal arteries) underwent DSA. Interpretation & conclusions: An association between UMRA and DSA findings was obtained in six patients (nine renal arteries), and these patients were stented. Post-procedure follow up showed good improvement in blood pressure and renal function. UMRA was found to be a useful non-invasive imaging modality to detect RAS in CKD patients. It can identify patients who require further invasive angiography and revascularization. PMID- 29578192 TI - Comparison of radiofrequency ablation alone & in combination with percutaneous ethanol injection for management of hepatocellular carcinoma. AB - Background & objective: It has been shown that the combined use of alcohol before radiofrequency ablation (RFA) helps to augment the therapeutic advantage of RFA. The present study was conducted to compare the outcome of treatment with RFA alone and RFA with alcohol as ablative technique in patients with small hepatocellular carcinomas (HCCs), who were not candidates for surgery. Methods: Fifty patients with chronic liver disease and concurrent HCC were enrolled in this prospective study. The patients were treated with either RFA alone (n=25) or RFA combined with alcohol (n=25). Patient outcome was evaluated, and the tumour recurrence and survival of the patients were assessed in the two groups. Results: The survival rates at six months in patients who completed at least six months of follow up were 84 and 80 per cent in patients treated with RFA alone and combination therapy, respectively. During the follow up period, 11 and four patients treated with RFA alone showed local and distant intrahepatic tumour recurrence, respectively. All local recurrences were at one to 18 months of the follow up period. The distant recurrences occurred at 6-36 months of the follow up period. During the follow up period, eight and six patients treated with combination therapy showed local and distant intrahepatic tumour recurrence, respectively. All local recurrences were at 1.5-15 months during the follow up period. The distant intrahepatic recurrences occurred at 6-72 months during the follow up period. Interpretation & conclusions: No significant difference was seen between the survival time of the patients treated with RFA alone and RFA with alcohol as well as in the local recurrences and distant intrahepatic recurrences in RFA compared to RFA and alcohol group patients. Combined use of RFA and alcohol did not improve the local tumour control and survival in patients with HCC compared to RFA alone. PMID- 29578193 TI - Interlink between cholesterol & cell cycle in prostate carcinoma. AB - Background & objectives: Earlier reports have shown hypocholesterolaemia in cancer patients and high number of lipid rafts in cancer cells. The primary objective of this study was to compare the intracellular cholesterol turnover in non-cancerous (benign) prostatic hyperplasia (BPH) and carcinoma prostate (CAP) with normal prostate cells obtained from patients undergoing radical cystectomy for carcinoma bladder (sham control). Methods: ELISA-based estimation of prostate specific antigen (PSA), evaluation of expression of low-density lipoprotein receptor (LDLR), peripheral-type benzodiazepine receptor (PBR) and cyclin E, immunohistochemistry and confocal microscopy, measurement of integrated optical density of the diaminobenzidine (DAB)-stained immunohistograms, isolation of nucleus and cell cytoplasm from prostate tissue by ultracentrifugation followed by estimation of cholesterol spectrophotometrically in isolated nuclear and cytoplasmic fractions were performed. Results: Seventy five individuals, 25 for each group (BPH n=25; CAP n=25 and sham control n=25), were included in the study. Cholesterol was increased in the cytoplasm and nucleus of the prostate cancer cells along with elevated expression of LDLR. Increased cholesterol concentration in the cell nucleus was found comparable with the increased expression of cholesterol transporter viz. PBR in the prostate tumour tissues as compared to its expression in normal prostate cells obtained from individuals undergoing radical cystectomy for carcinoma bladder. Cell cycle protein cyclin E was also highly expressed in cancer tissues. Interpretation & conclusions: The present findings along with increased expression of cell cycle protein cyclin E in the cell nucleus of the tumour tissue suggested the possibility of an intriguing role of cholesterol in the mechanism of cell cycle process of prostate cell proliferation. PMID- 29578194 TI - Effect of bone bank processing on bone mineral density, histomorphometry & biomechanical strength of retrieved femoral head. AB - Background & objectives: Standard processing of the bone grafts involves deep freezing and sterilization with gamma irradiation which may alter mechanical properties of the bone graft. This study was aimed at measuring the effect of bone bank processing on the mechanical properties of bone allograft and its correlation with bone mineral density [BMD, dual-energy X-ray absorptiometry (DEXA Scan)] and histomorphometric indices. Methods: Femoral heads retrieved from patients undergoing hip replacement surgeries were used as the material. Twenty femoral heads were under taken in the study. Each femoral head was cut into two equal cubes. One cube was subjected to BMD measurement using DEXA Scan followed by unilateral compression test. Histomorphometric indices such as trabecular number (Tb. N.), trabecular separation (Tb. S.), trabecular thickness (Tb. T.) and bone volume (B.V.) were calculated on the same specimen by a computer software. The other cube was kept in deep freezer (-76 degrees C) for a minimum of three weeks, followed by gamma irradiation and subjected to similar tests. Results: Results were compared in pre- and post-processed bone specimens. A significant loss of biomechanical strength (P<0.001) with mean a loss of 18.90 per cent was found in post-processed samples in uniaxial compression tests. Similarly, BMD (mean decrease by 13.8%, P<0.01) and histomorphometric indices such as Tb. T. (mean decrease by 12.37%, P<0.01), Tb. S. (mean increase by 12.60%, P<0.001) and B.V. (mean decrease by 20.84%, P<0.01) were found. However, Tb. N. was not significantly affected. Interpretation & conclusions: The current method of processing of bone allografts i.e. deep-freezing and gamma irradiation appeared to cause a significant reduction in the biomechanical strength of allogenic bone which was more suitable to be use in the morselized form. Appropriate consideration for decreased strength needs to be given when using allogenic bone graft as a structural graft.

AB - Background & objectives: There have been studies around the world on the prevalence of osteoporosis and its related risk factors, but there have been limited studies on risk factors and osteoporosis in the Indian population. In this study, the incidence of osteoporosis and the associated clinical risk factors (CRFs) were studied in the urban Indian population. Methods: Bone mineral density of 445 individuals >38 yr of age using qualitative ultrasound (QUS) was assessed. The patients were also questioned regarding the presence of the various CRFs as per the FRAX tool. The patients were categorized into normal, osteopenia and osteoporosis groups on the basis of T-score from QUS. Results: There were 223 males and 222 females in this study. Sex was significantly associated with T score (P<0.001). Forty (8.99%) patients were osteoporotic, 265 (59.55%) were osteopenic and the remaining 140 (31.46%) were normal. A significant association of T-score was found with parent history of fracture (P<0.05), rheumatoid arthritis (P<0.05) and secondary osteoporosis (P<0.05). Previous history of fracture's association was not found to be significant. Smoking, alcohol intake and steroid intake were not found to be significantly associated with T-scores. Interpretation & conclusions: The incidence of osteoporosis was found to be high in the urban Indian population. More care and attention should be targeted towards elderly, especially the ones with the risk factors to prevent osteoporosis in future. PMID- 29578196 TI - Comparison of Disease Activity Score in 28 joints with ESR (DAS28), Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) & Routine Assessment of Patient Index Data with 3 measures (RAPID3) for assessing disease activity in patients with rheumatoid arthritis at initial presentation. AB - Background & objectives: In patients with rheumatoid arthritis (RA), disease severity assessment is done using Disease Activity Score in 28 joints with ESR (DAS28). Computing DAS28 is time-consuming, requires laboratory testing and an online calculator. There is a need to validate rapid methods of disease severity assessment for routine daily use. This study was conducted to compare DAS28, Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire Disability Index (HAQ-DI) and Routine Assessment of Patient Index Data with 3 measures (RAPID3) to assess the disease activity in patients with RA. Methods: We prospectively studied the utility of CDAI, HAQ-DI and RAPID3 scoring in 100 consecutive newly diagnosed, disease modifying antirheumatic drugs (DMARDs) naive adult patients with RA seen during January 2013 and June 2014 at a tertiary care teaching hospital in south India. Results: The mean age of the patients was 42.1+/-11.6 yr, there were 82 females. The median [interquartile range (IQR)] symptom duration was 6 (range 4-12) months. The median (IQR) DAS28, CDAI, HAQ-DI and RAPID3 scores at presentation were 7 (6-7), 36 (28-43), 2 (1-2) and 17 (13 19), respectively. A significant positive correlation was observed between DAS28 and CDAI (r=0.568; P<0.001); DAS28 and HAQ-DI (r=0.304; P=0.002) and DAS28 and RAPID3 (r=0.404; P<0.001). A 'slight-to-fair' agreement was observed in between DAS28 and CDAI (kappa-statistic=0.296). The agreement between DAS28 and HAQ-DI (kappa-statistic=0.007) and RAPID3 (kappa-statistic=0.072) was less robust. Interpretation & conclusions: In adult patients with RA, in the setting where illiteracy is high, CDAI emerged as the preferred choice for rapid assessment of severity of disease at the time of initial presentation. PMID- 29578197 TI - Immunohistochemical expression of hypoxia-inducible factor-1alpha in stromal cells of vaginal tissue in post-menopausal women with pelvic organ prolapse. AB - Background & objectives: Pelvic organ prolapse (POP) is a common medical condition that affects adult women of different ages. The support of a normal pelvic floor is the result of complex interactions between ligaments, muscles, connective tissue and vaginal walls. Hypoxia and oxidative stress can reduce protein synthesis in the pelvic muscles that may contribute to muscular atrophy. Hypoxia-inducible factor-1alpha (HIF-1alpha) is a transcriptional activator which, expressed in response to hypoxia, activates a number of genes involved in cellular response to hypoxia. However, a potential role of hypoxia and oxidative stress in pathogenesis of POP is not known. This study was aimed to compare the level of HIF-1alpha immunohistochemical expression in the vaginal stromal cells of postmenopausal women with and without POP. Methods: Samples of the vaginal tissue from 120 menopausal women were obtained during surgery, and immunohistochemical expression of HIF-1alpha was assessed. There were 60 women with POP while 60 women in the control group were without prolapse but with benign gynaecological diseases. Results: In post-menopausal women with prolapse, significant differences were observed in the number of HIF-1alpha-positive stromal cells in the vaginal tissue compared to the control group. There was a significant increase in the number of HIF-1alpha in the stromal cells of the vaginal tissue in women with prolapse. Interpretation & conclusions: Difference in expression of HIF-1alpha in stromal cells of the vaginal tissue in the post menopausal women with and without POP suggests that prolonged hypoxia probably has an important role in the aetiopathogenesis of POP. PMID- 29578198 TI - Impact of attendance in a daycare centre on depression among elderly in rural Puducherry: A pre- & post-intervention study. AB - Background & objectives: Depression is higher in the elderly and in the rural areas in India. There is a need for interventions to reduce depression among the elderly and improve their quality of life (QOL). This study was conducted to assess the impact of attendance at a community-based daycare centre in rural Puducherry, India, on depression, cognitive impairment (CI) and QOL of the elderly. Methods: This was a before and after intervention study with a daycare centre set up in the village Thondamanatham in Puducherry, India, between January 2013 and January 2014. Socializing activities were held at the centre with psychological counselling. Depression was measured using Geriatric Depression Scale (GDS, short form), CI using the Hindi Mini-Mental Status Examination and QOL using WHO QOL BREF. Results: There were 99 males and 164 females; of whom 42.2 per cent attended the daycare centre at least once a month. Significantly higher proportions of elderly had depression among those with lower frequency of attendance at the daycare centre. Irrespective of the pre-intervention status, attendance at the daycare centre reduced the probability of depression by about 51 per cent. There was an improvement in the WHO QOL scores in the social domain among those who attended more than once a month. Interpretation & conclusions: GDS scores decreased and WHO QOL scores increased with increasing attendance at the daycare centre. Thus, the intervention was found to be effective in reducing depression and improving QOL of the elderly. PMID- 29578200 TI - Epigallocatechin gallate & curcumin prevent transforming growth factor beta 1 induced epithelial to mesenchymal transition in ARPE-19 cells. AB - Background & objectives: Proliferative vitreoretinopathy (PVR) is characterized by the presence of epiretinal membrane (ERM), which exerts traction and detaches the retina. Epithelial to mesenchymal transition (EMT) of the retinal pigment epithelial (RPE) cells underlies ERM formation. Adjuvant therapies aimed at preventing recurrence of PVR after surgery mostly failed in clinical trials. This study was aimed to evaluate the anti-EMT properties of bio-active compounds epigallocatechin gallate (EGCG), curcumin and lycopene as inhibitors of EMT induced by transforming growth factor beta 1 (TGF-beta1) in cultured ARPE-19 cells. Methods: ARPE-19 cells were treated with TGF-beta1 alone or co-treated with EGCG (1-50 MUM), lycopene (1-10 MUM) and curcumin (1-10 MUM). The mRNA and protein expression of EMT markers, alpha-smooth muscle actin, vimentin, zonula occludens-1 and matrix metalloproteinase-2 (MMP-2), were assessed by reverse transcription polymerase chain reaction/quantitative polymerase chain reaction and immunofluorescence/enzyme linked immunosorbent assay. Activity of MMP-2 was assessed by zymography. Functional implications of EMT were assessed by proliferation assay (MTT assay) and migration assay (scratch assay). Western-blot for phosphorylated Smad-3 and total Smad-3 was done to delineate the mechanism. Results: EGCG and curcumin at 10 MUM concentration reversed EMT, inhibited proliferation and migration through Smad-3 phosphorylation, when induced by TGF beta1 in ARPE-19 cells. Lycopene did not prevent EMT in ARPE-19 cells. Interpretation & conclusions: EGCG and curcumin are potent in preventing EMT induced by TGF-beta1 in ARPE-19 cells and therefore, proposed as potential molecules for further pre-clinical evaluation in PVR management. PMID- 29578201 TI - Use of covered stents in simultaneous management of coarctation of the aorta and patent ductus arteriosus. AB - OBJECTIVE: To report clinical and procedural characteristics of twelve patients who received a covered stent for the treatment of aortic coarctation and concurrent patent ductus arteriosus (PDA). METHODS: A single center database was retrospectively evaluated to obtain data of patients with combined aortic coarctation and PDA. We selected patients in whom a covered stent was used for the treatment of both pathologies. The stent length was chosen so as to cover the entire length of the lesion from healthy to healthy tissue and also cover the ampulla of PDA. RESULTS: The median age of the patients was 15 (range, 6.5-35) years. The diameter of the coarctated segment increased from a median of 8.4 (range, 2.6-10.8) mm to 16 (range, 9-24) mm (p<0.005), whereas the pressure gradient decreased from a median of 43 (range, 10-71) mm Hg to 0 (range, 0-8) mm Hg (p<0.005). Fourteen covered stents were used for 12 patients. Following deployment, seven stents were flared with larger and low-pressure balloons because of the gap between the distal end of the stent and the poststenotic dilated segment of the aorta, which caused residual PDA shunts and/or instability of the stent. After the procedure, no residual PDA shunt was present in any patient. CONCLUSION: To the best of our knowledge, this study includes the largest series of patients reported in literature in whom covered CP stents were used for simultaneous percutaneous treatment of coarctation and PDA. The procedure was successful and stable results were obtained during follow-up in all cases. PMID- 29578199 TI - Initial treatment dropout in patients with substance use disorders attending a tertiary care de-addiction centre in north India. AB - Background & objectives: Dropout from substance use disorders treatment is associated with poor outcomes. Although many factors have been associated with an early dropout of patients, the reasons for dropping out of treatment prematurely remain poorly understood particularly in the Indian context. This study was aimed to study socio-demographic and clinical variables predicting initial dropout of patients attending a tertiary care de-addiction treatment centre in north India. Methods: Information was extracted from the records of consecutive newly registered patients from January 2011 to December 2014. The patients who did not come for follow up within 30 days of the first contact were defined as initial dropouts. Results: Data of 7991 patients could be retrieved. Majority of the sample consisted of male, married and employed individuals. Of them, 4907 patients (61.3%) were considered initial dropouts. Multivariate analysis revealed that after controlling for other factors, greater age, being employed, lower educational status, lesser duration of substance use, use of alcohol, opiate, tobacco, cannabis or sedative-hypnotic use but the absence of multi-substance use predicted initial drop out. Interpretation & conclusions: This study identified some socio-demographic and clinical variables which might predict treatment attrition in substance use disorders. Clinician's awareness towards these factors and tailor-made intervention might improve initial treatment retention. Future research could be directed to find the validity of this assumption. PMID- 29578202 TI - The impact of the left ventricular pacing polarity and localization during cardiac resynchronization therapy on depolarization and repolarization parameters. AB - OBJECTIVE: Reversal of myocardial activation sequence during cardiac resynchronization therapy (CRT) may increase the transmural dispersion of repolarization (TDR), which may lead to ventricular arrhythmias. Quadripolar left ventricular (LV) leads offer 10 different pacing configurations. However, little is known about the role of pacing polarity on repolarization patterns. Our study aimed to investigate the impact of LV pacing polarity on depolarization and repolarization parameters in the same substrate in the same patient group. METHODS: This study prospectively analyzed 20 patients who were consecutively admitted and underwent CRT-D implantation with quadripolar LV leads. Two bipolar pacing vectors and two unipolar vectors, also called extended bipolar pacing vectors, from the same pacing sites were selected for comparison. Electrocardiogram markers of depolarization and repolarization were measured and compared. RESULTS: Bipolar LV pacing was associated with a significantly shorter QRS duration (basal, unipolar vs. bipolar, 135.1+/-17.8 vs. 119.3+/-14.5, p<0.01; non-basal, unipolar vs. bipolar, 134.4+/-15.7 vs. 121.9+/-10.3, p<0.01) and Tp-Te value (Basal, unipolar vs. bipolar, 119.1+/-36.7 vs. 97.6+/-27.9, p<0.05; non basal, unipolar vs. bipolar, 117.9+/-36.3 vs. 98.6+/-20.4, p<0.05) than those in unipolar pacing. LV pacing from basal and non-basal segments had no differential effect on the repolarization parameters. CONCLUSION: The LV pacing polarity significantly affects QRS duration but not repolarization patterns regardless of the pacing site in the same substrate. From the perspective of basal and non basal segments, the LV pacing site has no differential effect on the repolarization parameters. PMID- 29578203 TI - Coronary angiography using the left distal radial approach - An alternative site to conventional radial coronary angiography. AB - OBJECTIVE: To share our experience with the left distal radial approach for transradial coronary angiography and interventions. By performing the radial puncture in the fossa radialis or the so called anatomical "Snuffbox" we aimed to present the feasibility and complications of this new technique. METHODS: Left distal radial artery was used as an access site in 54 patients admitted to our clinic for coronary angiography and intervention between May 25th and October 20th 2017. All of them had pulse in their left distal radial artery. In the laboratory, they had their left arm gently flexed at the shoulder so that the hand was placed over their right groin. The operator stood on the right side of the patient and performed coronary angiography and interventions. During the hospital stay, demographic features and complications were recorded. RESULTS: Mean age of patients was 59.3 years and 80% were male. We used Judkins 6 French catheters for the procedures. Seventeen patients admitted with acute coronary syndrome. They all underwent successful left distal transradial coronary angiography and intervention. Primary angioplasty was performed in 10 patients. In total, 20 patients had coronary intervention. Left anterior descending artery was the artery requiring most intervention (11 patients). Two patients experienced brachial spasm requiring crossover to right femoral artery. There were no cases of radial artery occlusion, hematoma, or hand numbness. The radial sheath was removed at procedure termination. Hemostasis was achieved with manual compression. CONCLUSION: Left distal radial approach is safe and feasible as a new technique for coronary angiography and interventions. PMID- 29578204 TI - Differences in gene expression related to the outcomes of obesity treatment, peak oxygen uptake, and fatty acid metabolism measured in a cardiopulmonary exercise test. AB - INTRODUCTION The obesity pandemic requires development of methods that could be used on a large scale, such as the cardiopulmonary exercise test (CPET). Gene expression may explain CPET results on the molecular level. OBJECTIVES The aim of this study was to compare gene expression in obesity, depending on CPET results. PATIENTS AND METHODS The study group consisted of 9 obese patients and 7 controls. The treatment encompassed diet, rehabilitation, and behavioral therapy. Diet was based on the body composition analyzed by bioelectrical impedance, resting metabolic rate, and subjective patient preferences. The rehabilitation depended on the CPET results: maximal oxygen uptake and fatty acid metabolism. Behavioral intervention focused on the diagnosis of health problems leading to obesity, lifestyle modification, training in self-assessment, and development of healthy habits. The intensive treatment lasted for 12 weeks and consisted of consultations with a physician, dietitian, and medical rehabilitation specialist. RNA was isolated from the whole blood. A total of 47 323 transcripts were analyzed, of which 32 379 entities were confirmed to have high quality of RNA. RESULTS We observed differences in gene expression related to the CPET results indicating abnormalities in fat oxidation and maximal oxygen uptake. The genes with major differences in expression were: CLEC12A, HLA-DRB1, HLA-DRB4, HLA A29.1, IFIT1, and LOC100133662. CONCLUSIONS The differences in gene expression may account for the outcomes of treatment related to inflammation caused by obesity, which affects the muscles, fat tissue, and fatty acid metabolism.

PMID- 29578208 TI - Angiotensin-converting enzyme in innate and adaptive immunity. AB - Angiotensin-converting enzyme (ACE) - a zinc-dependent dicarboxypeptidase with two catalytic domains - plays a major part in blood pressure regulation by converting angiotensin I to angiotensin II. However, ACE cleaves many peptides besides angiotensin I and thereby affects diverse physiological functions, including renal development and male reproduction. In addition, ACE has a role in both innate and adaptive responses by modulating macrophage and neutrophil function - effects that are magnified when these cells overexpress ACE. Macrophages that overexpress ACE are more effective against tumours and infections. Neutrophils that overexpress ACE have an increased production of superoxide, which increases their ability to kill bacteria. These effects are due to increased ACE activity but are independent of angiotensin II. ACE also affects the display of major histocompatibility complex (MHC) class I and MHC class II peptides, potentially by enzymatically trimming these peptides. Understanding how ACE expression and activity affect myeloid cells may hold great promise for therapeutic manipulation, including the treatment of both infection and malignancy. PMID- 29578207 TI - Use of oral anticoagulants in patients with atrial fibrillation and renal dysfunction. AB - Atrial fibrillation (AF) and chronic kidney disease (CKD) are increasingly prevalent in the general population and share common risk factors such as older age, hypertension and diabetes mellitus. The presence of CKD increases the risk of incident AF, and, likewise, AF increases the risk of CKD development and/or progression. Both conditions are associated with substantial thromboembolic risk, but patients with advanced CKD also exhibit a paradoxical increase in bleeding risk. In the landmark randomized clinical trials that compared non-vitamin K antagonist oral anticoagulants (NOACs) with warfarin for thromboprophylaxis in patients with AF, the efficacy and safety of NOACs in patients with mild-to moderate CKD were similar to those in patients without CKD. Dose adjustment of NOACs as per the prescribing label is required in this population. Owing to limited trial data, evidence-based recommendations for the management of patients with AF and severe CKD or end-stage renal disease on dialysis are lacking. Observational cohort studies have reported conflicting results, and the management of these particularly vulnerable patients remains challenging and requires careful assessment of stroke and bleeding risk and, where appropriate, use of warfarin with good-quality anticoagulation control. PMID- 29578211 TI - DECLINING PREVALENCE OF HIV AND OTHER SEXUALLY TRANSMITTED INFECTIONS AMONG FEMALE SEX WORKERS IN JOS, NORTH-CENTRAL NIGERIA. AB - BACKGROUND: Female Sex Workers (FSWs) are key reservoirs of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) from which transmission to the general population fuels epidemics. STIs amplify HIV infectiousness and susceptibility. We determined the status of HIV and STIs among brothel-based FSWs in Jos as part of an ongoing prevention intervention. METHOD: Between January and May 2012, consenting consecutive brothel-based FSWs were recruited from previously designated brothels across Jos. HIV counseling and testing as well as screening for gonorrhoea, syphilis, trichomonasis, candidasis and Bacteria vaginosis (BV) were performed. Positive cases were provided free treatment and follow-up at Solat Women Hospital, Jos. Ethical clearance was obtained from Jos University Teaching Hospital (JUTH) ethical committee. RESULT: Two hundred FSWs aged 27.6 +/- 4.6 years (range 15-55 years) were recruited and of these, 47 (23.5%) were HIV Positive, 20 (10.0%) had syphilis, 9 (4.5%) had Neisseria gonorrhea, 3 (1.5%) had Trichomonas vaginalis and 86 (43.0%) had BV. The association between HIV and bacterial vaginosis was statistically significant (OR of 2.2, 95% CI of 1.1-4.2, P-value=0.02). In comparison to similar prevalence in 2006, the current findings represent 51.5% decline in HIV prevalence, 40.8% decline for syphilis and over 83.3% decline in prevalence for Trichomonas vaginalis. There was no significant change in the prevalence of Neisseria gonorrhoea and BV. CONCLUSION: The prevalence of HIV and STIs among brothel-based FSWs in Jos remain unacceptably high, although, there is a declining trend. A comprehensive HIV prevention program targeting these women is required to block transmission to the general population. PMID- 29578212 TI - Emerging chemical strategies for imprinting magnetism in graphene and related 2D materials for spintronic and biomedical applications. AB - Graphene, a single two-dimensional sheet of carbon atoms with an arrangement mimicking the honeycomb hexagonal architecture, has captured immense interest of the scientific community since its isolation in 2004. Besides its extraordinarily high electrical conductivity and surface area, graphene shows a long spin lifetime and limited hyperfine interactions, which favors its potential exploitation in spintronic and biomedical applications, provided it can be made magnetic. However, pristine graphene is diamagnetic in nature due to solely sp2 hybridization. Thus, various attempts have been proposed to imprint magnetic features into graphene. The present review focuses on a systematic classification and physicochemical description of approaches leading to equip graphene with magnetic properties. These include introduction of point and line defects into graphene lattices, spatial confinement and edge engineering, doping of graphene lattice with foreign atoms, and sp3 functionalization. Each magnetism-imprinting strategy is discussed in detail including identification of roles of various internal and external parameters in the induced magnetic regimes, with assessment of their robustness. Moreover, emergence of magnetism in graphene analogues and related 2D materials such as transition metal dichalcogenides, metal halides, metal dinitrides, MXenes, hexagonal boron nitride, and other organic compounds is also reviewed. Since the magnetic features of graphene can be readily masked by the presence of magnetic residues from synthesis itself or sample handling, the issue of magnetic impurities and correct data interpretations is also addressed. Finally, current problems and challenges in magnetism of graphene and related 2D materials and future potential applications are also highlighted.

PMID- 29578215 TI - alpha-Lipoic acid stabilized DTX/IR780 micelles for photoacoustic/fluorescence imaging guided photothermal therapy/chemotherapy of breast cancer. AB - Micellar nanoparticles have unique advantages as carriers for therapeutic or imaging agents, owing to their smaller size and better penetration of tumors. However, some agents, due to their physical or chemical properties, are difficult to load into micelles. IR780 is one of these agents, and is also a promising near infrared dye for fluorescence imaging (FI)/photoacoustic imaging (PAI) and cancer photothermal therapy (PTT). Its hydrophobic and high crystallization structure results in limited bioavailability in vivo. It is difficult to load into micelles constructed from an amphiphilic block polymer with relatively low molecular weight. In this study, we use computer simulation and introduce another small biomolecule, alpha-lipoic acid, into the micelles constructed from a mPEG-PCL copolymer, to lower the energy of molecular interaction between MPEG-PCL and IR780, and expect to enhance the loading capacity of the micelles to IR780. The introduction of alpha-lipoic acid decreases the energy of molecular interaction between MEPG-PCL and IR780 from -46.18 kJ mol-1 to -196.52 kJ mol-1 and increases the loading capacity and stability of the mPEG-PCL micelles to IR780, which also maintains the loading capacity to DTX. We further construct DTX/IR780 co-loaded mPEG-PCL micelles for FI/PAI dual modal imaging guided PTT/chemotherapy of cancer. By FI and PAI evaluation in vitro and in vivo, we demonstrate that the DTX/IR780 co-loaded micelles can be used as FI and PAI probes. By further evaluating the therapeutic outcome of PTT/chemotherapy co-therapy of breast cancer, we demonstrate that the DTX/IR780 co-loaded mPEG-PCL micelles can serve as promising candidates for FI and PAI guided PTT/chemotherapy of breast cancer.

AB - Dehydrogenative coupling of cyclic enones with heteroarenes has been a longstanding challenge because of the competitive ketone dehydrogenation and conjugated addition. Herein, a dehydrogenative coupling reaction of cyclic enones of different sizes with substituted thiophenes to construct beta-thienyl cyclic enone compounds through palladium-catalyzed C-H functionalization under mild reaction conditions is reported. Simple substituted thiophenes with different functional groups can be directly introduced into cyclic enones with predominant regioselectivity at the alpha position of thiophene moieties and excellent functional group tolerance. Further molecular transformations of the coupling products to synthetically useful meta-heteroarylated phenol derivatives have also been demonstrated. PMID- 29578220 TI - Unraveling the effects of amino acid substitutions enhancing lipase resistance to an ionic liquid: a molecular dynamics study. AB - Understanding of the structural and dynamic properties of enzymes in non-aqueous media (e.g., ionic liquids, ILs) is highly attractive for protein engineers and synthetic biochemists. Despite a growing number of molecular dynamics (MD) simulation studies on the influence of different ILs on wild-type enzymes, the effects of various amino acid substitutions on the stability and activity of enzymes in ILs remain to be unraveled at the molecular level. Herein, we selected fifty previously reported Bacillus subtilis lipase A (BSLA) variants with increased resistance towards an IL (15 vol% 1-butyl-3-methylimidazolium trifluoromethanesulfonate; [Bmim][TfO]), and also ten non-resistant BSLA variants for a MD simulation study to identify the underlying molecular principles. Some important properties differentiating resistant and non-resistant BSLA variants from wild-type were elucidated. Results show that, in 15 vol% [Bmim][TfO] aqueous solution, 40% and 60% of non-resistant variants have lower and equal probabilities to form a catalytically important hydrogen bond between S77 and H156 compared to wild-type, whereas 36% and 56% of resistant variants show increased and equal probabilities, respectively. Introducing positively charged amino acids close to the substrate-binding cleft for instance I12R is beneficial for the BSLA resistance towards 15 vol% [Bmim][TfO], likely due to the reduced probability of [Bmim]+ cations clustering near the cleft. In contrast, substitution with a large hydrophobic residue like I12F can block the cleft through hydrophobic interaction with a neighboring nonpolar loop 134-137 or/and an attractive pi-pi interaction with [Bmim]+ cations. In addition, the resistant variants having polar substitutions on the surface show higher ability to stabilize the surface water molecule network in comparison to non-resistant variants. This study can guide experimentalists to rationally design promising IL resistant enzymes, and contribute to a deeper understanding of protein-IL interactions at the molecular level.

AB - Aneurysmal subarachnoid hemorrhage (SAH) is the extravasation of blood into the subarachnoid space and is fatal in most cases. Platinum coils have been used to fill the hemorrhage site and prevent the extravasation of blood. Here we explored the use of Pt-coated polymer nanofibers (NF) to prevent blood extravasation and were able to achieve improved results in vitro. The polymer nanofibers were produced via electrospinning and were subsequently electroplated with Pt, resulting in metalized nanofibers. These nanofibers were installed within a microfluidic channel, and the resulting reduction in the permeability was evaluated using a fluid similar to blood. Based on the obtained results, these newly developed nanofibers are expected to decrease the operation cost for SAH, owing to their reduced size and low material cost. Furthermore, it is expected that these nanofibers will be used in a smaller amount during SAH operation while having the same preventive effect. This should reduce the operational risk associated with the multiple steps required to place the Pt coils at the SAH site. Finally, the underlying hydrodynamic mechanism responsible for the reduced permeability of the synthesized nanofibers is described.

AB - Anti-inflammatory and antioxidant properties have been attributed to constituents of Rosmarinus officinalis. Considering the inflammatory nature of arthritis and the oxidative stress induced by the disease, this work aimed to investigate if R. officinalis is able to attenuate oxidative and inflammatory injuries caused by the disease. Rats with complete Freund's adjuvant induced arthritis were used. An aqueous extract of the rosemary leaves was administered orally. The parameters related to oxidative stress were measured in the liver, brain and plasma. The administration of the rosemary extract (RE) to arthritic rats diminished oxidative damage (e.g., less carbonylated proteins), improved the oxidative state (e.g., less reactive oxygen species) and also increased the antioxidant capacity by increasing the GSH level and the GSH/GSSG ratio and by almost normalizing the activity of several antioxidant enzymes. The treatment of arthritic rats with the extract also diminished paw edema, the number of leukocytes recruited in the femoro-tibial joint cavities and the weight of the lymph nodes and delayed the appearance of secondary lesions. Twelve phenolic compounds were identified and quantified in the aqueous RE, rosmarinic acid being the most abundant one. In addition, the extract also contains polysaccharides and proteins. The anti inflammatory and antioxidant activities of the RE can be attributed, partly at least, to its content of polyphenolics with the strong possibility of synergistic interactions as well as metabolic activations. The results corroborate and amplify the general notion that rosemary aqueous extracts possess efficient anti inflammatory agents and suggest that they are able to attenuate the oxidative stress inherent to arthritis.

AB - We developed a dual-mode DNA nanoprobe based on covalent linkage for fluorescence imaging and photoacoustic imaging of tumor-related mRNA. PMID- 29578224 TI - Combining gold nanoparticle antennas with single-molecule fluorescence resonance energy transfer (smFRET) to study DNA hairpin dynamics. AB - The association of a plasmonic nano-antenna with single-molecule FRET technique presents new prospects to investigate the dynamics of biological molecules. However, the presence of a plasmonic nano-antenna significantly modifies the FRET rate and efficiency; this makes its applicability to the prevalent single molecule FRET experiments unclear. Herein, using gold nanoparticle antennas of different sizes and DNA hairpins labelled with FRET pairs (Cy3 and Cy5) as the model system, we performed experiments to study the folding dynamics of single DNA hairpins at various salt concentrations. Our results indicate that gold nanoparticle antennas can enhance single-molecule fluorescence of Cy3 and Cy5 up to 3-5 folds, substantially reduce the FRET efficiency, and alter the obtained FRET efficiency histograms. However, the folding dynamics of DNA hairpins remains unaffected, and the correct kinetic and dynamic information can still be extracted from the seriously modified FRET efficiencies. Therefore, our experiments demonstrate the feasibility and compatibility for applying plasmonic nano-antennas to the mostly used single-molecule FRET assays, which provide a broad range of possibilities for the future applications of these nano-antennas in studying various essential biological processes.

AB - By taking advantage of the layered structure and decent M-X bond strength of transition metal dichalcogenides (TMDCs), herein versatile Ti-MOFs were successfully prepared with layered titanium disulfide (TiS2) as the titanium source. In addition, the phase evolution mechanism, CO2 adsorption capacity and photocatalytic degradation performance of the prepared Ti-MOFs were investigated in detail. PMID- 29578226 TI - Site-selective bond scission of methylbenzoate following core excitation. AB - The chemical bond scission of methylbenzoate (C6H5CO2CH3) following core excitation at the C and O K edges was examined from partial ion yield measurements across these edges using synchrotron radiation. Site-specific scission of the C-O bonds was observed at both edges. Theoretical X-ray absorption spectra (XAS) were obtained using density functional theory. Peak assignments in the observed spectra were found to be consistent with the theory. From core-excited state dynamics calculations, an elongation of the C-O bond was predicted and provides an explanation of the observed partial ion yield enhancement of CH3+ and C6H5CO+ at the core-excited resonances at both edges. PMID- 29578227 TI - Upconversion thermometry: a new tool to measure the thermal resistance of nanoparticles. AB - The rapid evolution in luminescence thermometry in the last few years gradually shifted the research from the fabrication of more sensitive nanoarchitectures towards the use of the technique as a tool for thermal bioimaging and for the unveiling of properties of the thermometers themselves and of their local surroundings, for example to evaluate heat transport at unprecedented small scales. In this work, we demonstrated that KLu(WO4)2:Ho3+,Tm3+ nanoparticles are able to combine controllable heat release and upconversion thermometry permitting to estimate its thermal resistance (in air), a key parameter to model the heat transfer at the nanoscale.

AB - Contrary to the accepted wisdom that avoids cation symmetry for the sake of optimum electrolyte properties, we reveal outstanding behaviour for the diethylpyrrolidinium cation ([C2epyr]), in combination with the bis(fluorosulfonyl)imide (FSI) anion and Li[FSI]. The equimolar [C2epyr][Li][FSI]2 is a liquid with high conductivity, high Li transference number and >90% lithium metal cycling efficiency. The high level of performance for these electrolytes invites consideration of a new class of electrolytes for lithium batteries. PMID- 29578231 TI - Connectivity-driven bi-thermoelectricity in heteroatom-substituted molecular junctions. AB - To improve the thermoelectric performance of molecular junctions formed by polyaromatic hydrocarbon (PAH) cores, we present a new strategy for enhancing their Seebeck coefficient by utilizing connectivities with destructive quantum interference combined with heteroatom substitution. Starting from the parent PAH, with a vanishing mid-gap Seebeck coefficient, we demonstrate that the corresponding daughter molecule obtained after heteroatom substitution possesses a non-zero, mid-gap Seebeck coefficient. For the first time, we demonstrate a "bi thermoelectric" property, where for a given heteroatom and parent PAH, the sign of the mid-gap Seebeck coefficient depends on connectivity and therefore the daughter can exhibit both positive and negative Seebeck coefficients. This bi thermoelectric property is important for the design of tandem thermoelectric devices, where materials with both positive and negative Seebeck coefficients are utilized to boost the thermovoltage. Simple parameter-free rules for predicting the Seebeck coefficient of such molecules are presented, which form a powerful tool for designing efficient molecular thermoelectric devices.

AB - Sheet-like graphene tends to stack with each other in thin films, resulting in relatively smooth microstructures with increased reflection as the thickness increases. In contrast, when the sheets are crumpled into a shape like paper balls, reflection is greatly reduced. In this work, crumpled graphene balls are found to be strong light absorbers in the visible and near-infrared regions. Average absorption of thin films made of crumpled graphene balls can reach up to 97.4% in the wavelength region of 350-2500 nm. When crumpled graphene balls are used as the solar absorber for the interfacial evaporation system, an evaporation efficiency of 84.6% was obtained under one sun at ambient pressure. Enhanced solar absorption of crumpled graphene balls, coupled with their aggregation resistance and universal solution processability, makes them promising candidates for solar heating/distillation applications. PMID- 29578233 TI - Tuning the surface of Au nanoparticles using poly(ethylene glycol)-block poly(propylene glycol)-block-poly(ethylene glycol): enzyme free and label free sugar sensing in serum samples using resonance Rayleigh scattering spectroscopy. AB - Poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (F 108) functionalized gold nanoparticles (Au NPs) have been successfully synthesized. During synthesis it is found that an increase in the F-108 concentration contributes to agglomeration in the media, increasing the size of the Au particles, and boosting the curcumin concentration leads to a higher density of functional groups, resulting in smaller Au NPs. FT-IR analysis reveals that the hydroxyl and phenolic groups of curcumin and F-108 are involved during the functionalization of Au surfaces. Enhancement in the fluorescence/RRS intensity is due to the combination of the influence of the shape/size of the Au NPs as well as the extent of curcumin conjugation at the interface of the Au NP surface and F-108. The presence of sugar molecules remarkably boosts the RRS intensity without significantly affecting the fluorescence and surface plasmon absorbance of the Au NPs; in contrast, the RRS intensity of standard CTAB functionalized Au NPs is unaffected by glucose molecules indicating that the functionalization of F-108 at Au surfaces is crucial. Interestingly, no interference from other potential interferents and antioxidant substances like ascorbic acid, creatinine and acetaminophen is observed. This method is simple and fast, and offers a wider linear dynamic range, 0-10 mM, that is applicable under physiological conditions and in serum samples. It is stable and provides an excellent recovery for serum samples, thus, potentially it can be useful in this field due to its low energy consumption, enzyme free assay, fast response time, better selectivity and sensitivity. PMID- 29578234 TI - Cardiac myoglobin participates in the metabolic pathway of selenium in rats. AB - As an essential micronutrient, selenium deficiency is a leading cause of cardiovascular diseases. The heart is continuously beating to deliver blood to the entire body, and this requires a high amount of energy. An adult heart normally obtains 50-70% of its adenosine 5'-triphosphate from fatty acid beta oxidation. An increase in fatty acid oxidation activity induces the generation of larger amounts of by-products (reactive oxygen species, ROS) from mitochondrial oxidative phosphorylation. Selenium-dependent glutathione peroxidases play a critical role in the removal of these ROS, especially organic hydroperoxides, from the heart. The definitive transport and/or detailed metabolic pathways from the selenium-source compounds to the selenoproteins in the heart still remain unclear. We explored the selenium-binding proteins in a rat cardiac cell lysate using its reactive metabolic intermediate, selenotrisulfide (STS), and MALDI TOF mass spectrometry. Several proteins with a free cysteine (Cys) thiol were found to be reactive with STS through a thiol-exchange reaction. The most distinctive Cys-containing protein in the cardiac cell lysate was identified as myoglobin (Mb) from a rat protein database search and tryptic fragmentation experiments. When separately examined in selenium adequate rats, selenium-binding to the cardiac Mb was verified using selenium-specific fluorometry. Cardiac Mb is thought to participate in the selenium metabolic pathway in the heart. PMID- 29578235 TI - Quantum spin Hall effect in two-dimensional hydrogenated SnPb alloy films. AB - Using first-principles calculations, we studied the geometric and band structures of 20 possible configurations of buckled hydrogenated SnPb alloy (SnxPb8-xH8) films. The configurations are topological insulators (TIs) when x >= 1. When x increases from 1 to 7, the band gap increases from 0.087 eV to 0.98 eV. The topological characteristics are suggested by s-pxy band inversion and confirmed by helical edge states, which are time-reversal symmetry protected. According to spin-orbit coupling (SOC) analysis results, we draw the conclusion that the Pb atoms have greater SOC strength than the Sn atoms, so when the number ratio of Pb and Sn atoms is greater than 1/12 the SOC strength is large enough to trigger the band inversion between the s and pxy orbitals, causing the SnPb alloy film to turn into a topological insulator (TI) from a normal band insulator (NI). We give a simple rule for the topological criterion of hydrogenated SnPb alloy films by comparing the ratio of Pb and Sn atoms. This would provide a useful reference for the design of topological devices based on NI-TI hetero-junctions for experiments. PMID- 29578236 TI - Clustering and assembly dynamics of a one-dimensional microphase former. AB - Both ordered and disordered microphases ubiquitously form in suspensions of particles that interact through competing short-range attraction and long-range repulsion (SALR). While ordered microphases are more appealing materials targets, understanding the rich structural and dynamical properties of their disordered counterparts is essential to controlling their mesoscale assembly. Here, we study the disordered regime of a one-dimensional (1D) SALR model, whose simplicity enables detailed analysis by transfer matrices and Monte Carlo simulations. We first characterize the signature of the clustering process on macroscopic observables, and then assess the equilibration dynamics of various simulation algorithms. We notably find that cluster moves markedly accelerate the mixing time, but that event chains are of limited help in the clustering regime. These insights will inspire further study of three-dimensional microphase formers. PMID- 29578237 TI - Nutritional supplements for patients being treated for active visceral leishmaniasis. AB - BACKGROUND: Visceral leishmaniasis (VL) is a disease caused by a parasite, which can lead to death if untreated. Poor nutritional status hastens the progression of VL infection, and VL worsens malnutrition status. Malnutrition is one of the poor prognostic factors identified for leishmaniasis. However, the effects of nutritional supplementation in people treated for VL are not known. OBJECTIVES: To assess the effects of oral nutritional supplements in people being treated with anti-leishmanial drug therapy for VL. SEARCH METHODS: We searched the Cochrane Infectious Diseases Group (CIDG) Specialized Register, CENTRAL, MEDLINE, Embase, LILACS, and two trial registers up to 12 September 2017. We checked conference proceedings and WHO consultative meeting reports, the reference lists of key documents and existing reviews, and contacted experts and nutritional supplement companies. SELECTION CRITERIA: Randomized controlled trials (RCTs), quasi-randomized controlled trials (quasi-RCTs), and non-randomized controlled trials (NRCTs) of any oral nutritional supplement, compared to no nutritional intervention, placebo, or dietary advice alone, in people being treated for VL. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the literature search results for studies that met the inclusion criteria. We had planned for two review authors to independently extract data and assess the risk of bias of the included studies. We planned to follow the Cochrane standard methodological procedures for assessing risk of bias and analysing the data. MAIN RESULTS: We identified no eligible studies for this review, either completed or ongoing. AUTHORS' CONCLUSIONS: We found no studies, either completed or ongoing, that assessed the effects of oral nutritional supplements in people with VL who were being treated with anti-leishmanial drug therapy. Thus, we could not draw any conclusions on the impact of these interventions on primary cure of VL, definitive cure of VL, treatment completion, self-reported recovery from illness or resolution of symptoms, weight gain, increased skinfold thickness, other measures of lean or total mass, or growth in children.This absence of evidence should not be interpreted as evidence of no effect for nutritional supplements in people under VL treatment. It means that we did not identify research that fulfilled our review inclusion criteria.The effects of oral nutritional supplements in people with VL who are being treated with anti-leishmanial drug therapy have yet to be determined by rigorous experimental studies, such as cluster-randomized trials, that focus on outcomes relevant for patients. PMID- 29578238 TI - Development of the AAS Statement on "Suicide" and "Physician Aid in Dying". AB - In August 2017, the American Association of Suicidology board passed a statement titled "Suicide" is not the same as "Physician aid in dying," which was developed partly in response to the fact that aid in dying is now legal in a number of jurisdictions. In Phase 1, eight members of the AAS who had indicated interest in this issue were asked to independently draft such a statement; the convener consolidated these drafts and comments into an initial statement. In Phase 2, five additional experts who might be expected to object were asked for their independent input; the convener consolidated these with the previous draft. No one objected to the statement altogether; extensive copyediting and rewording suggestions focused primarily on issues of overlap between "suicide" and "physician aid in dying." The resulting document represents an effort to try to accommodate the basic concerns of all participants. The document does not speak for or against legalization of this practice, but it may have bearing on whether suicide prevention professionals have an obligation to try to prevent such deaths and whether they may serve as consultants for psychological or psychiatric evaluations as sometimes required under US state law. PMID- 29578239 TI - Prediction of Liquid Specific Heat Capacity of Food Lipids. AB - : Specific heat capacity (cp ) is a temperature dependent physical property of foods. Lipid-being a macromolecular component of food-provides some fraction of the food's overall heat capacity. Fats/oils are complex chemicals that are generally defined by carbon length and degree of unsaturation. The objective of this investigation was to use advanced specific heat capacity measurement to determine the effect of fatty acid chemical structure on specific heat capacity of food lipids. In this investigation, the specific heat capacity of a series of triacylglycerols were measured to quantify the influence of fatty acid composition on specific heat capacity based on two parameters; the -average carbon number (C) and the average number of double bonds (U). A prediction model for specific heat capacity of food lipids as a function of C, U and temperature (T) has been developed. A multiple linear regression to the three-parameter model (R2 = 0.87) provided a good fit to the experimental data. The prediction model was evaluated by comparison with previously published specific heat capacity values of vegetable oils. It was found that the model provided a 0.53% error, while three other models from the literature predicted cp values with 0.85% to 1.83% average relative deviation from experimental data. The outcomes from this research confirm that the thermophysical properties of fat present in foods are directly related to the physical chemical properties. PRACTICAL APPLICATION: The specific heat capacity of food products is widely used in process design. Improvements of current models to predict specific heat capacity of food products will assist in the development of efficient processes and in the control of food quality and safety. Furthermore, the understanding of how changes in chemical structure of macromolecular components of foods effect thermophysical properties may begin to allude to models that are not just empirical, but represent portions of the differences in chemistry.

PMID- 29578241 TI - Psychometric properties of the suffering assessment questionnaire in adults with chronic diseases or life-threatening illness. AB - BACKGROUND: Suffering has been considered by many authors to be a difficult concept to assess and measure, as it is subjective and unique. However, to guide the diagnosis and decision-making of healthcare professionals, it is important to develop an instrument that differentiates the different suffering dimensions, namely, intra- and interpersonal suffering, awareness of suffering and spiritual suffering. AIM: The aim of this study was thus to design and validate an instrument for the assessment of the dimensions of suffering in adult patients with chronic diseases or life-threatening illnesses. METHOD: A methodological study was developed. The data were collected from two self-help organisations and a palliative care unit. The theoretical model was tested using confirmatory factor analysis. The study sample consisted of 251 patients with chronic diseases or life-threatening illnesses. The Sense of Coherence Scale, the Spiritual Assessment Scale and the Suffering Assessment Questionnaire in Adults with Chronic Diseases or Life-Threatening Illness (SAQ) were applied to each participant and were later returned for analysis. RESULTS: An SAQ version with 12 items showed adequate psychometric characteristics of validity and internal consistency after being adapted to a four-dimensional structure that assesses the four dimensions of suffering. CONCLUSION: The results of confirmatory analysis indicated a good model fit that suggested that the advocated theoretical model is plausible. PMID- 29578243 TI - Clusters of Suicidal Events Among Young People: Do Clusters from One Time Period Predict Later Clusters? AB - We sought to compare clusters of suicidal events between two different time periods and examine the extent to which earlier clusters predict later clusters. We included data on suicides and suicide attempts from New South Wales between July 2001 and June 2012 and Western Australia between January 2000 and December 2011. Suicide attempts included admissions to hospital for deliberate self-harm and suicides were deaths due to deliberate self-harm. We combined data on suicides and suicide attempts and grouped them into two equal time periods. We detected clusters in each period using Poisson discrete scan statistics adjusted for socio-economic status. We estimated the predictive values of earlier clusters on later clusters. The results showed that clusters from earlier time period had a moderate power (36%) in predicting later clusters. During the later time period, some additional cluster areas (14%) were found and some earlier cluster areas subsided (64%). Historical clusters predict 36% of the subsequent clusters, which is probably not sufficient for targeting interventions. Our study highlights the need for other strategies to detect emerging clusters, for example, up-to-date data. PMID- 29578242 TI - Proanthocyanidin-Rich Grape Seed Extract Modulates Intestinal Microbiota in Ovariectomized Mice. AB - : Grape-seed extract (GSE) is rich in proanthocyanidins (polymers of flavan-3 ols). GSE is well known to have various beneficial effects to health. The objective of this study was to examine the effect of dietary GSE on the intestinal microbiota in ovariectomized (OVX) mice as a model of menopause. Phylum-level analyses using 16S rRNA-targeted group-specific polymerase-chain reaction primers in fecal samples collected 8 weeks postoperatively from OVX mice revealed that the proportion of Firmicutes and Bacteroidetes populations became imbalanced as compared with that in sham-operated control mice. That is, the ratio of Firmicutes:Bacteroidetes populations in the OVX group were increased significantly. When OVX animals were given dietary GSE, the imbalanced proportion of Firmicutes and Bacteroidetes populations was normalized to that seen in control mice. In addition, the body weight of OVX animals measured at 6 weeks postoperatively was significantly higher than that in sham-operated control animals. Dietary GSE also prevented OVX animals from increasing body weight. Thus, we postulated that GSE can improve imbalanced populations of intestinal microbiota, leading to prevention of obesity under conditions of not only menopause but morbidity. PRACTICAL APPLICATION: The GSE has a great potential to be a functional food to improve dysbiosis in post-menopausal women. PMID- 29578244 TI - The Fallen. PMID- 29578245 TI - Genome-wide analysis of Glycine soja ubiquitin (UBQ) genes and functional analysis of GsUBQ10 in response to alkaline stress. AB - Ubiquitin is a highly conserved protein with multiple essential regulatory functions through the ubiquitin-proteasome system. Even though its functions in the ubiquitin-mediated protein degradation pathway are very well characterized, the function of ubiquitin genes in the regulation of the alkaline stress response is not fully established. In this study, we identified 12 potential UBQ genes in the Glycine soja genome, and analyzed their evolutionary relationship, conserved domains and promoter cis-elements. We also explored the expression profiles of G. soja UBQ genes under alkaline stress, based on the transcriptome sequencing. We found that the expression of GsUBQ10 was significantly induced by alkaline stress, and the function of GsUBQ10 was characterized by overexpression in transgenic alfalfa (Medicago sativa). Our results suggested that GsUBQ10 transgenic lines significantly improved the alkaline tolerance in alfalfa. The GsUBQ10 transgenic lines showed lower relative membrane permeability, lower malon dialdehyde content and higher catalase activity than in the wild-type plants. This indicates that GsUBQ10 is involved in regulating the reactive oxygen species accumulation under alkaline stress. Taken together, we identified an ubiquitin gene GsUBQ10 from G. soja, which plays a positive role in responses to alkaline stress in alfalfa. PMID- 29578246 TI - Psychological Impairment as a Predictor of Suicide Ideation in Individuals with Anorexia Nervosa. AB - Anorexia nervosa (AN) is an eating disorder characterized by severe food restriction resulting in low body weight and an intense fear of gaining weight. This disorder has one of the highest suicide rates of any psychiatric illness; however, few studies have investigated prospective predictors of suicide ideation (SI) in this population. Quality-of-life impairment may be particularly relevant for understanding suicide risk in AN, given associations with SI in other psychiatric disorders and associations with chronicity and severity in AN. This study explored associations between eating disorder-related impairment and SI in individuals with AN (n = 113) who completed assessments at treatment discharge and 3, 6, and 12 months after discharge. Greater psychological impairment predicted future occurrence of SI controlling for age, depression, history of SI, and eating disorder variables. Associations were specific to psychological impairment as other domains of impairment did not predict SI over time. Findings highlight the potential importance of targeting interpersonal-psychological consequences of AN to decrease future suicide risk. PMID- 29578247 TI - Benzo[a]pyrene-decreased gap junctional intercellular communication via calcium/calmodulin signaling increases apoptosis in TM4 cells. AB - The mechanism of male reproductive toxicity induced by benzo[a]pyrene (BaP) is poorly understood. Gap junctional intercellular communication (GJIC) is known to play a critical role in maintaining spermatogenesis. The aim of the present study was to determine the toxic effects of BaP in Sertoli cells, and to explore the possibility and potential mechanisms of BaP-induced changes in the level of GJIC, and the relationship between GJIC and BaP-induced apoptosis. We treated mouse Sertoli cell lines (TM4) with different concentrations (0.1-100 MUm) of BaP for 1 48 hours, and found that GJIC exhibited a dose- and time-dependent downregulation. Treatment with 10 MUm BaP increased apoptosis, intracellular Ca2+ level ([Ca2+ ]i ) and calmodulin (CaM) protein expression, and decreased the protein level of connexin 43 (Cx43) (also known as gap junction alpha-1 protein [GJA1]) in TM4 cells. However, BaP had no effect on the phosphorylation of Cx43 at Ser279/282, Ser255, Ser368 or Ser262. Downregulation of [Ca2+ ]i by BAPTA-AM significantly attenuated the BaP-induced GJIC suppression, Cx43 protein decrease and CaM protein increase. Interestingly, inhibition of CaM expression by W7 partially recovered BaP-induced GJIC inhibition, but had no effect on BaP-induced Cx43 protein decrease. Pretreatment with the GJIC activator retinoic acid significantly mitigated BaP-induced apoptosis. In conclusion, these results suggest that BaP can decrease GJIC via Ca2+ /CaM signaling, and that BaP-induced GJIC suppression increases apoptosis in TM4 cells. PMID- 29578248 TI - Incidence and related factors for intraoperative failed spinal anaesthesia for lower limb arthroplasty. AB - BACKGROUND: Spinal anaesthesia is the preferred choice for total hip- and knee arthroplasty (THA/TKA), due to the claimed superior outcome profile, relative simple technique and without the need for advanced airway support. However, choosing and informing about spinal anaesthesia should also include the risk for intraoperative failed spinal anaesthesia with associated pain, discomfort and suboptimal settings for airway management. Small-scale studies suggest incidences from 1 to 17%; however, no multi-institutional large data exists on failed spinal incidence and related factors during THA/TKA, hindering evidence-based information and potential anaesthesia stratification. METHODS: In a sub-analysis, data from a prospective study on spinal anaesthesia for THA/TKA were examined for incidence of intraoperative conversion to general anaesthesia. Potential perioperative factors (age, gender, American Society of Anaesthesiologist (ASA) score, height, weight, BMI, procedure, bupivacaine dosage and duration of time from spinal administration until end of surgery) were analysed with logistic regression for relation to failed spinal anaesthesia. RESULTS: In all, 1451 patients were included for analysis, whereof 57 (3.9%) had failed spinal anaesthesia. Spinal failure patients were significantly younger (61 vs. 67 years, P = 0.003), and operation time longer in the failed spinal group vs no-failure, respectively (133 vs. 89 min, P < 0.001). No significant differences were found with regard to bupivacaine volume, gender, ASA-score, height, weight, BMI or THA vs. TKA. CONCLUSION: Failed spinal anaesthesia for THA and TKA is a relatively frequent occurrence and identification of risk patients is not feasible. These results should be considered when choosing anaesthesia and included in the information to patients. PMID- 29578249 TI - Preoperative vitamin D deficiency increases the risk of postoperative cognitive dysfunction: a predefined exploratory sub-analysis. AB - BACKGROUND: Vitamin D is important for maintaining physiological functions including cognition and its deficiency is associated with the occurrence of cognitive impairment. This study was to explore the association between preoperative vitamin D status and the occurrence of postoperative cognitive dysfunction (POCD) in elderly patients undergoing major surgery. METHODS: This was a predefined exploratory sub-analysis of one-centre data from a randomized controlled trial. In all, 123 elderly (>= 65 years) patients who were scheduled to undergo major cancer surgery were recruited. Serum 25-hydroxyvitamin D concentration was measured before surgery. In total, 59 nonsurgical control subjects with comparable age and education level were also enrolled. A battery of neuropsychological tests was administered the day before and the 7th day after surgery in patients or at the same time interval in control subjects. POCD was diagnosed according to the ISPOCD1 definition. RESULTS: 71.5% (88/123) of elderly patients had vitamin D deficiency (serum 25-hydroxyvitamin D concentration < 12 ng/ml) before surgery; 24.4% (30/123) of them developed cognitive dysfunction at 1 week after surgery. After adjusting for confounding factors, high preoperative serum 25-hydroxyvitamine D concentration was related to a decreased risk of POCD (odds ratio [OR]: 0.829, 95% confidence interval [CI]: 0.708-0.971; P = 0.020), whereas preoperative vitamin D deficiency was associated with an increased risk of POCD (OR: 8.427, 95% CI: 1.595-44.511; P = 0.012). CONCLUSIONS: Vitamin D deficiency is prevalent in elderly patients undergoing major cancer surgery and increases the risk of early POCD development. Whether prophylactic vitamin D supplementation can reduce POCD in the elderly deserves further study. PMID- 29578250 TI - Vasopressin and nitroglycerin decrease portal and hepatic venous pressure and hepato-splanchnic blood flow. AB - BACKGROUND: Various methods are used to reduce venous blood pressure in the hepato-splanchnic circulation, and hence minimise blood loss during liver surgery. Previous studies show that combination of vasopressin and nitroglycerin reduces portal pressure and flow in patients with portal hypertension, and in this study we investigated this combination in patients with normal portal pressure. METHOD: In all, 13 patients were studied. Measurements were made twice to confirm baseline (C1 and BL), during vasopressin infusion 4.8 U/h (V), and during vasopressin infusion combined with nitroglycerin infusion (V + N). Portal venous pressure (PVP), hepatic venous pressure (HVP), central haemodynamics and arterial and venous blood gases were obtained at each measuring point, and portal (splanchnic) and hepato-splanchnic blood flow changes were calculated. RESULTS: Vasopressin alone did not affect PVP, whereas HVP increased slightly. In combination with nitroglycerin, PVP decreased from 10.1 +/- 1.6 to 8.9 +/- 1.3 mmHg (P < 0.0001), and HVP decreased from 7.9 +/- 1.9 to 6.2 +/- 1.3 mmHg (P = 0.001). Vasopressin reduced portal blood flow by 47 +/- 19% and hepatic venous flow by 11 +/- 18%, respectively. Addition of nitroglycerin further reduced portal- and hepatic flow by 55 +/- 13% and 30 +/- 13%, respectively. Vasopressin alone had minor effects on central haemodynamics, whereas addition of nitroglycerin reduced cardiac index (3.2 +/- 0.7 to 2.7 +/- 0.5; P < 0.0001). The arterial-portal vein lactate gradient was unaffected. CONCLUSION: The combination of vasopressin and nitroglycerin decreases portal pressure and hepato-splanchnic blood flow, and could be a potential treatment to reduce bleeding in liver resection surgery.

AB - Stopping declines in biodiversity is critically important, but it is only a first step toward achieving more ambitious conservation goals. The absence of an objective and practical definition of species recovery that is applicable across taxonomic groups leads to inconsistent targets in recovery plans and frustrates reporting and maximization of conservation impact. We devised a framework for comprehensively assessing species recovery and conservation success. We propose a definition of a fully recovered species that emphasizes viability, ecological functionality, and representation; and use counterfactual approaches to quantify degree of recovery. This allowed us to calculate a set of 4 conservation metrics that demonstrate impacts of conservation efforts to date (conservation legacy); identify dependence of a species on conservation actions (conservation dependence); quantify expected gains resulting from conservation action in the medium term (conservation gain); and specify requirements to achieve maximum plausible recovery over the long term (recovery potential). These metrics can incentivize the establishment and achievement of ambitious conservation targets. We illustrate their use by applying the framework to a vertebrate, an invertebrate, and a woody and an herbaceous plant. Our approach is a preliminary framework for an International Union for Conservation of Nature (IUCN) Green List of Species, which was mandated by a resolution of IUCN members in 2012. Although there are several challenges in applying our proposed framework to a wide range of species, we believe its further development, implementation, and integration with the IUCN Red List of Threatened Species will help catalyze a positive and ambitious vision for conservation that will drive sustained conservation action.

PMID- 29578252 TI - Development of health-related quality of life and symptoms in patients with advanced cancer in Greenland. AB - A prospective national cohort study assessed the development of health-related quality of life (HRQoL) and symptoms in adult patients undergoing treatment and care for advanced cancer in Greenland. HRQol was examined by EORTC QLQ-C30 version 3.0 questionnaire monthly for 4 months. Changes over time and between group comparisons were examined. Of 58 patients included in the study, 47% completed the questionnaire four times. Functioning was generally high, and improved social functioning was observed after 1 and 2 months. The highest symptom score was for fatigue followed by pain and nausea/vomiting. A high score for financial problems remained unchanged during the entire period. Patients with higher income had reduced pain intensity (p = .03) and diarrhoea (p = .05) than patients with income below the poverty line. After 1 month, reduction in pain intensity was observed for Nuuk citizens compared with non-Nuuk citizens (p = .05). After 2 months, non-Nuuk citizens reported improved social functioning compared with Nuuk citizens (p = .05). After 3 months, Global Health in Nuuk citizens was improved compared with non-Nuuk citizens (p = .05). An important clinical finding was that patients' needs for support are related to social status, and geographical factors should be taken into account when planning palliative care.

AB - INTRODUCTION: In haemophilia, recurrent joint bleeds are responsible for the development of chronic joint damage, because blood induces biochemical changes in joint structures. Joint degeneration is a long process, and structural damage is often preceded by joint dysfunction, which is represented by quantitative and qualitative changes in the contraction pattern of muscles around the joints. Muscle function in patients with haemophilia is still poorly investigated. AIM: The aim of this 2-year prospective study was to assess the changes in muscle function of lower limbs in a group of patients affected with haemophilia in San Jose, Costa Rica. METHODS: Muscle function of lower limbs was assessed by means of surface electromyography (sEMG) accomplished at study enrolment and after 2 years of follow-up. Gluteus medius, vastus medialis, biceps femoris, gastrocnemius and tibialis anterior were examined. All patients underwent concurrent clinical examination using Haemophilia Joint Health Score (HJHS). RESULTS: Sixty patients aged 2-43 years with severe haemophilia underwent clinical and sEMG evaluation. Thirty-two patients (53%) had target joints. sEMG parameters were altered in all patients and were not correlated to the presence of target joints and/or an abnormal HJHS. Muscle function deterioration was observed after 2 years of follow-up despite an unmodified HJHS. CONCLUSIONS: Muscle function of lower limbs as detected by means of sEMG was impaired in patients with haemophilia irrespective of the presence of overt joint damage. sEMG is a simple and sensitive assessment tool able to detect muscle dysfunction and so favouring the implementation of early rehabilitation therapy. PMID- 29578255 TI - Partial pancreatic transdifferentiation of primary human hepatocytes in the livers of a humanised mouse model. AB - BACKGROUND: Gene therapy is one treatment that may ultimately cure type 1 diabetes. We have previously shown that the introduction of furin-cleavable human insulin (INS-FUR) to the livers in several animal models of diabetes resulted in the reversal of diabetes and partial pancreatic transdifferentiation of liver cells. The present study investigated whether streptozotocin-diabetes could be reversed in FRG mice in which chimeric mouse-human livers can readily be established and, in addition, whether pancreatic transdifferentiation occurred in the engrafted human hepatocytes. METHODS: Engraftment of human hepatocytes was confirmed by measuring human albumin levels. Following delivery of the empty vector or the INS-FUR vector to diabetic FRG mice, mice were monitored for weight and blood glucose levels. Intraperitoneal glucose tolerance tests (IPGTTs) were performed. Expression levels of pancreatic hormones and transcription factors were determined by a reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. RESULTS: Diabetes was reversed for a period of 60 days (experimental endpoint) after transduction with INS-FUR. IPGTTs of the insulin transduced animals were not significantly different from nondiabetic animals. Immunofluorescence microscopy revealed the expression of human albumin and insulin in transduced liver samples. Quantitative RT-PCR showed expression of human and mouse endocrine hormones and beta-cell transcription factors, indicating partial pancreatic transdifferentiation of mouse and human hepatocytes. Nonfasting human C-peptide levels were significantly higher than mouse levels, suggesting that transdifferentiated human hepatocytes made a significant contribution to the reversal of diabetes. CONCLUSIONS: These data show that human hepatocytes can be induced to undergo partial pancreatic transdifferentiation in vivo, indicating that the technology holds promise for the treatment of type 1 diabetes. PMID- 29578256 TI - The nutrition impact symptoms (NIS) score detects malnutrition risk in patients admitted to nephrology wards. AB - BACKGROUND: Nutritional screening tools recommended for the general hospitalised population do not always adequately detect malnutrition risk in patients with kidney disease. The present study assessed the validity and reliability of the Nutrition Impact Symptoms (NIS) score as a nutrition screening tool for hospitalised inpatients prefer in nephrology wards. METHODS: Nutritional status was classified using Subjective Global Assessment (SGA). NIS scores were calculated from the total score of responses to questions assessing symptoms impacting upon nutritional status from the patient-generated SGA. Concurrent validity of NIS score was assessed using a receiver operating characteristic curve to predict malnutrition risk against SGA. Predictive validity was examined against length of hospital stay (LOS) and 30-day re-admission using Poisson and logistic regression, respectively. Inter-rater reliability of NIS scoring between assessors was determined using intraclass correlation. RESULTS: In 143 patients [90 males; mean (SD) age 57.8 (15.8) years], malnutrition prevalence was 38% (54/143) using SGA (rating B/C). Predicting malnutrition risk with an NIS score of >=3 had a sensitivity of 0.89 and a specificity of 0.65 (area under the curve = 0.81 [95% confidence interval (CI) = 0.74-0.88]). For each 1-point increase in NIS score, the model predicted a 1.9% rise in the risk of an increased LOS (P = 0.002). Thirty-day re-admission was not associated with NIS score. Inter-rater reliability was moderate (mean difference = 0.53; intraclass correlation coefficient = 0.74; 95% CI = 0.57-0.85). CONCLUSIONS: Nutrition impact symptoms score is a valid stand-alone nutrition screening tool for identifying malnutrition risk in nephrology inpatients and is associated with LOS. PMID- 29578257 TI - An automated quantitative DNA image cytometry system detects abnormal cells in cervical cytology with high sensitivity. AB - OBJECTIVE: To evaluate the performance of an automated DNA-image-cytometry system as a tool to detect cervical carcinoma. METHODS: Of 384 liquid-based cervical cytology samples with available biopsy follow-up were analyzed by both the Imager System and a high-risk HPV test (Cobas). RESULTS: The sensitivity and specificity of Imager System for detecting biopsy proven high-grade squamous intraepithelial lesion (HSIL, cervical intraepithelial neoplasia [CIN]2-3) and carcinoma were 89.58% and 56.25%, respectively, compared to 97.22% and 23.33% of HPV test but additional HPV 16/18 genotyping increased the specificity to 69.58%. The sensitivity and specificity of the Imager System for predicting HSIL+ (CIN2-3+) lesions among atypical squamous cells of undetermined significance samples were 80.00% and 70.53%, respectively, compared to 100% and 11.58% of HPV test whilst the HPV 16/18 genotyping increased the specificity to 77.89%. Among atypical squamous cells-cannot exclude HSIL, the sensitivity and specificity of Imager System for predicting HSIL+ (CIN2-3+) lesions upon follow up were 82.86% and 33.33%%, respectively, compared to 97.14% and 4.76% of HPV test and the HPV 16/18 genotyping increased the specificity to 19.05%. Among low-grade squamous intraepithelial lesion cases, the sensitivity and specificity of the Imager System for predicting HSIL+ (CIN2-3+) lesions were 66.67% and 35.71%%, respectively, compared to 66.67% and 29.76% of HPV test while HPV 16/18 genotyping increased the specificity to 79.76%. The overall results of imager and high-risk HPV test agreed in 69.43% (268) of all samples. CONCLUSIONS: The automated imager system and HPV 16/18 genotyping can enhance the specificity of detecting HSIL+ (CIN2-3+) lesions.

AB - Dynamic regulation of the interactions between specific molecules on functional surfaces and biomolecules, for example, proteins or cells, is critical for biosensor and biomedical devices. Herein, we present a spiropyran (SP)-based light-responsive surface coating, hPG (hyperbranched polyglycerol)-SP, to control the adsorption of proteins and adhesion of cells. In the normal state, the SP groups on the coating surface were in hydrophobic ring-closed form, which promotes the nonspecific protein adsorption and cell adhesion. Under UV irradiation, the grafted SP groups were dynamically isomerized into hydrophilic/zwitterionic merocyanine. Both hydrophilicity and zwitterions support the formation of a hydrated layer and hence the resulting hPG-MC coatings highly resist protein adsorption and cell adhesion. Moreover, the presented hPG also provided a robust bioinert background to suppress the nonspecific protein adsorption and cells adhesion. Therefore, this functionalized coating exhibited a good photoregulated antifouling behavior. Moreover, the detachment of adsorbed proteins and adhered cells from the coating surface was also realized. PMID- 29578260 TI - Dynamic multivoxel-localized 31 P MRS during plantar flexion exercise with variable knee angle. AB - Exercise studies investigating the metabolic response of calf muscles using 31 P MRS are usually performed with a single knee angle. However, during natural movement, the distribution of workload between the main contributors to force, gastrocnemius and soleus is influenced by the knee angle. Hence, it is of interest to measure the respective metabolic response of these muscles to exercise as a function of knee angle using localized spectroscopy. Time-resolved multivoxel 31 P MRS at 7 T was performed simultaneously in gastrocnemius medialis and soleus during rest, plantar flexion exercise and recovery in 12 healthy volunteers. This experiment was conducted with four different knee angles. PCr depletions correlated negatively with knee angle in gastrocnemius medialis, decreasing from 79+/-14 % (extended leg) to 35+/-23 %(~40 degrees ), and positively in soleus, increasing from 20+/-21 % to 36+/-25 %; differences were significant. Linear correlations were found between knee angle and end-exercise PCr depletions in gastrocnemius medialis (R2 =0.8) and soleus (R2 =0.53). PCr recovery times and end-exercise pH changes that correlated with PCr depletion were consistent with the literature in gastrocnemius medialis and differences between knee angles were significant. These effects were less pronounced in soleus and not significant for comparable PCr depletions. Maximum oxidative capacity calculated for all knee angles was in excellent agreement with the literature and showed no significant changes between different knee angles. In conclusion, these findings confirm that plantar flexion exercise with a straight leg is a suitable paradigm, when data are acquired from gastrocnemius only (using either localized MRS or small surface coils), and that activation of soleus requires the knee to be flexed. The present study comprises a systematic investigation of the effects of the knee angle on metabolic parameters, measured with dynamic multivoxel 31 P MRS during muscle exercise and recovery, and the findings should be used in future study design. PMID- 29578261 TI - Disparities exist between the dietary intake of Indigenous Australian women during pregnancy and the Australian dietary guidelines: the Gomeroi gaaynggal study. AB - BACKGROUND: Little is known about the adequacy of nutrient intakes and the overall diet quality of Indigenous Australian pregnant women. The aim of this cross-sectional study was to assess nutrient sufficiency and diet quality, as measured using the Australian Recommended Food Score (ARFS), in pregnant women from the Gomeroi gaaynggal cohort (n = 58). METHODS: Maternal dietary intake during pregnancy was assessed using the Australian Eating Survey Food Frequency Questionnaire, which was self-administered in the third trimester. Diet quality was determined using the ARFS. Food group servings and nutrient intakes were compared to the Australian Guide to Health Eating (AGHE) and Australian Nutrient Reference Values (NRVs). The current analysis examined the adequacy of usual intakes from food sources only, excluding supplements. RESULTS: None of the women met all AGHE daily food group serving recommendations. The highest alignment rates were for dairy (33%), meat/alternatives (31%) and vegetables (29.3%). Almost 93% of participants exceeded the recommended intake of energy-dense, nutrient-poor foods and percentage energy from saturated fat was high (15%). Of the five key nutrients for optimal reproductive health (folate, iron, calcium, zinc and fibre), the nutrients with the highest percentage of pregnant women achieving the NRVs were zinc (77.6%) and folate (68.9%), whereas iron was the lowest. Only one person achieved all NRVs (folate, iron, calcium, zinc and fibre) important in pregnancy. The median ARFS was 28 points (maximum of 73). CONCLUSIONS: Although the small cohort limits the generalisability of the findings of the present study, the data obtained indicate that the diets of these Indigenous pregnant women are inadequate. Therefore, strategies aiming to optimise nutrient intakes of Indigenous pregnant women are needed urgently. PMID- 29578262 TI - MicroRNA-guided gene expression in prostate cancer: Literature and database overview. AB - Insight into the aberrant expression of microRNAs (miRNAs) and the genes that they regulate during the progression of cancer in general and prostate cancer (PCa) in particular is one of the most important issues in current molecular biomedicine and allows for the discovery of therapeutic or diagnostic miRNA targets. The present study aimed to analyze the available data regarding the direct or indirect effects of miRNAs on the expression of the mRNAs involved in carcinogenesis and to enable updating and optimizing the selection of the corresponding targets. The present review focuses on the data related to the genes with miRNA-dependent expression during the development of PCa. The data used in this review have been extracted from research papers and the databases STRING, PANTHER and TargetScan, with a special focus on the genes directly associated with cell transformation and the maintenance of the transformed genotype, as well as tumor invasion and spread. The search for miRNA markers of PCa and therapeutically active molecules should rely on bioinformatics resources, such as data from recent experimental studies, as well as meta-analysis and cross analysis of the data on the state of the tumor, patient status, histological/immunohistological data and data on mRNA-miRNA coexpression. PMID- 29578263 TI - Telomere length determined by the fluorescence in situ hybridisation distinguishes malignant and benign cells in cytological specimens. AB - BACKGROUND: Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes that play a key role in preventing chromosomal instability. The aim of the present study is to determine telomere length using fluorescence in situ hybridisation (FISH) on cytological specimens. METHODS: Aspiration samples (n = 41) were smeared on glass slides and used for FISH. RESULTS: Telomere signal intensity was significantly lower in positive cases (cases with malignancy, n = 25) as compared to negative cases (cases without malignancy, n = 16), and the same was observed for centromere intensity. The difference in DAPI intensity was not statistically significant. The ratio of telomere to centromere intensity did not show a significant difference between positive and negative cases. There was no statistical difference in the signal intensities of aspiration samples from ascites or pleural effusion (n = 23) and endoscopic ultrasound-guided FNA samples from the pancreas (n = 18). CONCLUSIONS: The present study revealed that telomere length can be used as an indicator to distinguish malignant and benign cells in cytological specimens. This novel approach may help improve diagnosis for cancer patients. PMID- 29578264 TI - Influence of Different Implant Geometry in Clinical Longevity and Maintenance of Marginal Bone: A Systematic Review. AB - PURPOSE: To assess, through a systematic review, the influence of different implant geometries on clinical longevity and maintenance of marginal bone tissue. METHODS: An electronic search was conducted in MEDLINE, Scopus, and Web of Science databases, limited to studies written in English from 1996 to 2017 using specific search strategies. Only randomized controlled trials (RCTs) that compared dental implants and their geometries were included. Two reviewers independently selected studies, extracted data, and assessed the risk of bias of included studies. RESULTS: From the 4006 references identified by the search, 24 were considered eligible for full-text analysis, after which 10 studies were included in this review. A similar behavior of marginal bone loss between tapered and cylindrical geometries was observed; however, implants that had micro-threads in the neck presented a slight decrease of marginal bone loss compared to implants with straight or smooth neck. Success and survival rates were high, with cylindrical implants presenting higher success and survival rates than tapered ones. CONCLUSIONS: Implant geometry seems to have little influence on marginal bone loss (MBL) and survival and success rates after 1 year of implant placement; however, the evidence in this systematic review was classified as very low due to limitations such as study design, sample size, and publication bias. Thus, more well-designed RCTs should be conducted to provide evidence regarding the influence of implant geometry on MBL and survival and success rates after 1 year of implant placement.

AB - The synthesis and self-assembly in thin-film configuration of linear ABC triblock terpolymer chains consisting of polystyrene (PS), poly(2-vinylpyridine) (P2VP), and polyisoprene (PI) are described. For that purpose, a hydroxyl-terminated PS-b P2VP (45 kg mol-1 ) building block and a carboxyl-terminated PI (9 kg mol-1 ) are first separately prepared by anionic polymerization, and then are coupled via a Steglich esterification reaction. This quantitative and metal-free catalyst synthesis route reveals to be very interesting since functionalization and purification steps are straightforward, and well-defined terpolymers are produced. A solvent vapor annealing (SVA) process is used to promote the self assembly of frustrated PS-b-P2VP-b-PI chains into a thin-film core-shell double gyroid (Q230 , space group: Ia3-d) structure. As terraces are formed within PS-b P2VP-b-PI thin films during the SVA process under a CHCl3 vapor, different plane orientations of the Q230 structure ((211), (110), (111), and (100)) are observed at the polymer-air interface depending on the film thickness. PMID- 29578266 TI - Diagnostic performance of cone beam computed tomography in assessing peri-implant bone loss: A systematic review. AB - OBJECTIVES: To evaluate the diagnostic performance of cone beam computed tomography (CBCT) in the assessment of peri-implant bone loss and analyze its influencing factors. MATERIALS AND METHODS: Clinical and preclinical studies reporting diagnostic outcomes of CBCT imaging of peri-implant bone loss compared to direct reference measurements were sought by searching five electronic databases, PubMed, MEDLINE, EMBASE, Web of Science, and CINAHL Plus, and OpenGrey. QUADAS-2 criteria were adapted for quality analysis of the included studies. A qualitative synthesis was performed. Two meta-analysis models (random effects and mixed-effects) summarized the area under receiver operating characteristic (AUC) curve observations reported in the selected studies. The mixed-effects meta-analysis model evaluated three possible influencing factors, "defect type," "defect size," and "study effect." RESULTS: The initial search yielded 3,716 titles, from which 18 studies (13 in vitro and 5 animal) were included. Diagnostic accuracy of CBCT was fair to excellent in detecting in vitro circumferential-intrabony and fenestration defects, but moderate to low for peri implant dehiscences, and tended to be higher for larger defect sizes. Both, over- and underestimation of linear measurements were reported for the animal models. The meta-analyses included 37 AUC observations from eight studies. The random effects model showed significant heterogeneity. The mixed-effects model exhibited also significant but lower heterogeneity, and "defect type" and "study effect" significantly influenced the variability of AUC observations. CONCLUSION: In vitro, CBCT performs well in detecting peri-implant circumferential-intrabony or fenestration defects but less in depicting dehiscences. Influencing factors due to other site-related and technical parameters on the diagnostic outcome need to be addressed further in the future studies. PMID- 29578267 TI - A Review on Recent Developments and Prospects for the Oxygen Reduction Reaction on Hollow Pt-alloy Nanoparticles. AB - Due to their interesting electrocatalytic properties for the oxygen reduction reaction (ORR), hollow Pt-alloy nanoparticles (NPs) supported on high-surface area carbon attract growing interest. However, the suitable synthesis methods and associated mechanisms of formation, the reasons for their enhanced specific activity for the ORR, and the nature of adequate alloying elements and carbon supports for this type of nanocatalysts remain open questions. This Review aims at shedding light on these topics with a special emphasis on hollow PtNi NPs supported onto Vulcan C (PtNi/C). We first show how hollow Pt-alloy/C NPs can be synthesized by a mechanism involving galvanic replacement and the nanoscale Kirkendall effect. Nickel, cobalt, copper, zinc, and iron (Ni, Co, Cu, Zn, and Fe, respectively) were tested for the formation of Pt-alloy/C hollow nanostructures. Our results indicate that metals with standard potential 0.4=6 months from the Swedish HF Registry. Logistic regression analysis identified independent associations between 39 demographic, clinical, co-treatment, and socioeconomic predictors and MRA non-use. Of 11 215 patients, 27% were women; mean age was 75 +/- 11 years; only 4443 (40%) patients received MRA. Selected characteristics independently associated with MRA non-use were in descending order of magnitude: lower creatinine clearance (<60 mL/min), no need for diuretics, no cardiac resynchronization therapy/implantable cardioverter-defibrillator, higher blood pressure, no digoxin use, higher ejection fraction, outpatient setting, older age, lower income, ischaemic heart disease, male sex, follow-up in primary vs. specialty care, lower NYHA class, and absence of hypertension diagnosis. Plasma potassium and N-terminal pro B-type natriuretic peptide levels were not associated with MRA non-use. CONCLUSION: Mineralocorticoid receptor antagonists remain underused in HFrEF. Their use does not decrease with elevated potassium but does with impaired renal function, even in the creatinine clearance 30-59.9 mL/min range where MRAs are not contraindicated. MRA underuse may be further related to non-specialist care, milder HF and no use of other HF therapy.

AB - Peripartum cardiomyopathy is an idiopathic cardiomyopathy presenting with heart failure secondary to left ventricular systolic dysfunction towards the end of pregnancy or in the months following delivery, where no other cause for heart failure is identified. Outcome varies from full recovery to residual left ventricular systolic dysfunction and even death. Many women return to their physician to acquire information on their long-term prognosis, to seek medical advice regarding contraception, or when planning a subsequent pregnancy. This position paper summarizes current evidence for long-term outcome, risk stratification of further pregnancies and overall management. Based on the best available evidence, as well as the clinical experience of the European Society of Cardiology Study Group on Peripartum Cardiomyopathy members, a consensus on pre- and postpartum management algorithms for women undergoing a subsequent pregnancy is presented. PMID- 29578285 TI - Comparative Proteomics Analysis Reveals Trans Fatty Acid Isomers Activates Different Pathways in Human Umbilical Vein Endothelial Cell. AB - Trans fatty acid (TFA), a group of unsaturated fats with at least one double bond in the trans configuration, plays a role in lipid metabolism, the structure of the cell membrane phospholipids, and apoptosis. Previous studies demonstrated that TFA was associated with coronary heart disease, obesity, and insulin resistance. Herein, a quantitative proteomics approach estimated the relative abundance of proteins in human umbilical vein endothelial cells treated with TFA (two different TFA structural isomers: 9t-18:1 and 9t,12t-18:2). The results revealed that 174 identified proteins were significantly altered with respect to expression. Furthermore, based on the cutoff values, 35 proteins were differentially expressed in the 9t-18:1 group as compared to the control group, 69 proteins were differentially expressed in 9t,12t-18:2 group as compared to the control group, and 120 proteins were differentially expressed in the 9t,12t-18:2 group as compared to the 9t-18:1 group. Based on the bioinformatics analysis, we found that TFA could alter the structural constitution of the cytoskeleton through protein interactions, localization into the cell membrane, and incorporation into the phospholipid of the cell. In addition, 17 differential apoptosis-related proteins, including cell division cycle 42, superoxide dismutase 1, glyoxalase I, and macrophage migration inhibitory factor were also identified. Together, these results might emphasize the need for studying TFA induced biological processes.

PMID- 29578287 TI - Enhanced spectrofluorimetric determination of two novel combination therapies for the treatment of benign prostatic hyperplasia containing tamsulosin hydrochloride. AB - Two novel combination therapies for the treatment of benign prostatic hyperplasia were analyzed using simple and enhanced spectrofluorimetric methods based on derivative and derivative ratio techniques. The two combinations contained tamsulosin hydrochloride (TAM) as a minor component with tolterodine tartrate (TOL) or solifenacin succinate (SOL). The fluorescence of the three drugs under study was measured in methanolic water solution. For the TAM and SOL mixture, successful resolution between both drugs was achieved by derivative manipulation of both ratio and zero-order emission spectra with good linearity in the ranges of 0.75-3.50 and 2.5-15.0 MUg ml-1 for TAM and SOL, respectively. Extensive emission spectral overlap was observed for the TAM and TOL mixture. Therefore, only derivative application of the ratio emission spectra resolved such overlap and quantitated TAM and TOL simultaneously in the ranges 0.75-3.50 and 2.5-20.0 MUg ml-1 for TAM and TOL, respectively. Optimization of various experimental parameters that affected the fluorescence intensity of the three drugs was performed. Successful application of all proposed methods was achieved for analysis of the two drugs in each combination therapy in their laboratory prepared mixtures and dosage forms with good accuracy and precision. PMID- 29578288 TI - Differential growth of pavement cells of Arabidopsis thaliana leaf epidermis as revealed by microbead labeling. AB - PREMISE OF THE STUDY: In numerous vascular plants, pavement cells of the leaf epidermis are shaped like a jigsaw-puzzle piece. Knowledge about the subcellular pattern of growth that accompanies morphogenesis of such a complex shape is crucial for studies of the role of the cytoskeleton, cell wall and phytohormones in plant cell development. Because the detailed growth pattern of the anticlinal and periclinal cell walls remains unknown, our aim was to measure pavement cell growth at a subcellular resolution. METHODS: Using fluorescent microbeads applied to the surface of the adaxial leaf epidermis of Arabidopsis thaliana as landmarks for growth computation, we directly assessed the growth rates for the outer periclinal and anticlinal cell walls at a subcellular scale. KEY RESULTS: We observed complementary tendencies in the growth pattern of the outer periclinal and anticlinal cell walls. Central portions of periclinal walls were characterized by relatively slow growth, while growth of the other wall portions was heterogeneous. Local growth of the periclinal walls accompanying lobe development after initiation was relatively fast and anisotropic, with maximal extension usually in the direction along the lobe axis. This growth pattern of the periclinal walls was complemented by the extension of the anticlinal walls, which was faster on the lobe sides than at the tips. CONCLUSIONS: Growth of the anticlinal and outer periclinal walls of leaf pavement cells is heterogeneous. The growth of the lobes resembles cell elongation via diffuse growth rather than tip growth. PMID- 29578289 TI - Timing is everything: Dichogamy and pollen germinability underlie variation in autonomous selfing among populations. AB - PREMISE OF THE STUDY: The evolution of multiple floral traits often underlies the transition from outcrossing to selfing. Such traits can influence the ability to self, and the timing at which selfing occurs, which in turn affects the costs of selfing. Species that display variation in autonomous selfing provide an opportunity to dissect the phenotypic changes that contribute to variability in the mating system. METHODS: In a common garden, we measured dichogamy and herkogamy in 24 populations of the protandrous mixed-mating herb Campanula americana, and related these to autonomous fruit set (autonomy). We then measured the timing of self-pollen deposition and fruit production in populations with high and low autonomy, and determined whether pollen germinability across floral development contributes to variation in autonomy. KEY RESULTS: Populations that transitioned more rapidly to female phase displayed elevated autonomous selfing, but herkogamy was unassociated with autonomous selfing. Selfing occurred more rapidly in highly autonomous populations because of greater self-pollen deposition early in female phase. Pollen germinability in low-autonomy populations remained constant across floral development, but in high-autonomy populations it increased after floral anthesis and was highest near the onset of female phase. CONCLUSIONS: Reduced dichogamy, elevated self-pollen deposition, and higher pollen germination late in male phase contribute to both earlier selfing and greater selfing. These traits vary among populations, likely reflecting past selection on the mating system. While delayed selfing bears fewer fitness costs, the evolution of earlier selfing may be favored if self-pollen availability decreases over floral development. PMID- 29578290 TI - Limited pollen dispersal, small genetic neighborhoods, and biparental inbreeding in Vallisneria americana. AB - PREMISE OF THE STUDY: Pollen dispersal is a key process that influences ecological and evolutionary dynamics of plant populations by facilitating sexual reproduction and gene flow. Habitat loss and fragmentation have the potential to reduce pollen dispersal within and among habitat patches. We assessed aquatic pollen dispersal and mating system characteristics in Vallisneria americana-a water-pollinated plant with a distribution that has been reduced from historic levels. METHODS: We examined pollen neighborhood size, biparental inbreeding, and pollen dispersal, based on seed paternity using the indirect paternity method KinDist, from samples of 18-39 mothers and 14-20 progeny per mother from three sites across 2 years. KEY RESULTS: On average, fruits contained seeds sired by seven fathers. We found significant biparental inbreeding and limited pollen dispersal distances (0.8-4.34 m). However, in a number of cases, correlated paternity did not decline with distance, and dispersal could not be reliably estimated. CONCLUSIONS: Frequent pollen dispersal is not expected among patches, and even within patches, gene flow via pollen will be limited. Limited pollen dispersal establishes genetic neighborhoods, which, unless overcome by seed and propagule dispersal, will lead to genetic differentiation even in a continuous population. Unless loss and fragmentation drive populations to extreme sex bias, local pollen dispersal is likely to be unaffected by habitat loss and fragmentation per se because the spatial scale of patch isolation already exceeds pollen dispersal distances. Therefore, managing specifically for pollen connectivity is only relevant over very short distances.

AB - PREMISE OF THE STUDY: Dimensions and spatial distribution of vessels are critically important features of woody stems, allowing for adaptation to different environments through their effects on hydraulic efficiency and vulnerability to embolism. Although our understanding of vessel development is poor, basipetal transport of auxin through the cambial zone may play an important role. METHODS: Stems of Populus tremula *alba were treated with the auxin transport inhibitor N-1-naphthylphthalamic acid (NPA) in a longitudinal strip along the length of the lower stem. Vessel lumen diameter, circularity, and length; xylem growth; tension wood area; and hydraulic conductivity before and after a high pressure flush were determined on both NPA-treated and control plants. KEY RESULTS: NPA-treated stems formed aberrant vessels that were short, small in diameter, highly clustered, and angular in cross section, whereas xylem formed on the untreated side of the stem contained typical vessels that were similar to those of controls. NPA-treated stems had reduced specific conductivity relative to controls, but this difference was eliminated by the high-pressure flush. The control treatment (lanolin + dimethyl sulfoxide) reduced xylem growth and increased tension wood formation, but never produced the aberrant vessel patterning seen in NPA-treated stems. CONCLUSIONS: These results are consistent with a model of vessel development in which basipetal polar auxin transport through the xylem-side cambial derivatives is required for proper expansion and patterning of vessels and demonstrate that reduced auxin transport can produce stems with altered stem hydraulic properties. PMID- 29578292 TI - Vessel-associated cells in angiosperm xylem: Highly specialized living cells at the symplast-apoplast boundary. AB - BACKGROUND: Vessel-associated cells (VACs) are highly specialized, living parenchyma cells that are in direct contact with water-conducting, dead vessels. The contact may be sparse or in large tight groups of parenchyma that completely surrounds vessels. VACs differ from vessel distant parenchyma in physiology, anatomy, and function and have half-bordered pits at the vessel-parenchyma juncture. The distinct anatomy of VACs is related to the exchange of substances to and from the water-transport system, with the cells long thought to be involved in water transport in woody angiosperms, but where direct experimental evidence is lacking. SCOPE: This review focuses on our current knowledge of VACs regarding anatomy and function, including hydraulic capacitance, storage of nonstructural carbohydrates, symplastic and apoplastic interactions, defense against pathogens and frost, osmoregulation, and the novel hypothesis of surfactant production. Based on microscopy, we visually represent how VACs vary in dimensions and general appearance between species, with special attention to the protoplast, amorphous layer, and the vessel-parenchyma pit membrane. CONCLUSIONS: An understanding of the relationship between VACs and vessels is crucial to tackling questions related to how water is transported over long distances in xylem, as well as defense against pathogens. New avenues of research show how parenchyma-vessel contact is related to vessel diameter and a new hypothesis may explain how surfactants arising from VAC can allow water to travel under negative pressure. We also reinforce the message of connectivity between VAC and other cells between xylem and phloem.

PMID- 29578294 TI - From the sap's perspective: The nature of vessel surfaces in angiosperm xylem. AB - PREMISE OF THE STUDY: Xylem sap in angiosperms moves under negative pressure in conduits and cell wall pores that are nanometers to micrometers in diameter, so sap is always very close to surfaces. Surfaces matter for water transport because hydrophobic ones favor nucleation of bubbles, and surface chemistry can have strong effects on flow. Vessel walls contain cellulose, hemicellulose, lignin, pectins, proteins, and possibly lipids, but what is the nature of the inner, lumen-facing surface that is in contact with sap? METHODS: Vessel lumen surfaces of five angiosperms from different lineages were examined via transmission electron microscopy and confocal and fluorescence microscopy, using fluorophores and autofluorescence to detect cell wall components. Elemental composition was studied by energy-dispersive X-ray spectroscopy, and treatments with phospholipase C (PLC) were used to test for phospholipids. KEY RESULTS: Vessel surfaces consisted mainly of lignin, with strong cellulose signals confined to pit membranes. Proteins were found mainly in inter-vessel pits and pectins only on outer rims of pit membranes and in vessel-parenchyma pits. Continuous layers of lipids were detected on most vessel surfaces and on most pit membranes and were shown by PLC treatment to consist at least partly of phospholipids. CONCLUSIONS: Vessel surfaces appear to be wettable because lignin is not strongly hydrophobic and a coating with amphiphilic lipids would render any surface hydrophilic. New questions arise about these lipids and their possible origins from living xylem cells, especially about their effects on surface tension, surface bubble nucleation, and pit membrane function. PMID- 29578295 TI - Intercontinental dispersal and whole-genome duplication contribute to loss of self-incompatibility in a polyploid complex. AB - PREMISE OF THE STUDY: Angiosperm species often shift from self-incompatibility to self-compatibility following population bottlenecks. Across the range of a species, population bottlenecks may result from multiple factors, each of which may affect the geographic distribution and magnitude of mating-system shifts. We describe how intercontinental dispersal and genome duplication facilitate loss of self-incompatibility. METHODS: Self and outcross pollinations were performed on plants from 24 populations of the Campanula rotundifolia polyploid complex. Populations spanned the geographic distribution and three dominant cytotypes of the species (diploid, tetraploid, hexaploid). KEY RESULTS: Loss of self incompatibility was associated with both intercontinental dispersal and genome duplication. European plants were largely self-incompatible, whereas North American plants were intermediately to fully self-compatible. Within both European and North American populations, loss of self-incompatibility increased as ploidy increased. Ploidy change and intercontinental dispersal both contributed to loss of self-incompatibility in North America, but range expansion did not affect self-incompatibility within Europe or North America. CONCLUSIONS: When species are subject to population bottlenecks arising through multiple factors, each factor can contribute to self-incompatibility loss. In a widespread polyploid complex, the loss of self-incompatibility can be predicted by the cumulative effects of whole-genome duplication and intercontinental dispersal.

AB - PREMISE OF THE STUDY: Changing climates are expected to affect the abundance and distribution of global vegetation, especially plants and lichens with an epiphytic lifestyle and direct exposure to atmospheric variation. The study of epiphytes could improve understanding of biological responses to climatic changes, but only if the conditions that elicit physiological performance changes are clearly defined. METHODS: We evaluated individual growth performance of the epiphytic lichen Evernia mesomorpha, an iconic boreal forest indicator species, in the first year of a decade-long experiment featuring whole-ecosystem warming and drying. Field experimental enclosures were located near the southern edge of the species' range. KEY RESULTS: Mean annual biomass growth of Evernia significantly declined 6 percentage points for every +1 degrees C of experimental warming after accounting for interactions with atmospheric drying. Mean annual biomass growth was 14% in ambient treatments, 2% in unheated control treatments, and -9% to -19% (decreases) in energy-added treatments ranging from +2.25 to +9.00 degrees C above ambient temperatures. Warming-induced biomass losses among persistent individuals were suggestive evidence of an extinction debt that could precede further local mortality events. CONCLUSIONS: Changing patterns of warming and drying would decrease or reverse Evernia growth at its southern range margins, with potential consequences for the maintenance of local and regional populations. Negative carbon balances among persisting individuals could physiologically commit these epiphytes to local extinction. Our findings illuminate the processes underlying local extinctions of epiphytes and suggest broader consequences for range shrinkage if dispersal and recruitment rates cannot keep pace. PMID- 29578297 TI - High-throughput sequencing data clarify evolutionary relationships among North American Vitis species and improve identification in USDA Vitis germplasm collections. AB - PREMISE OF THE STUDY: Grapes are one of the most economically important berry crops worldwide, with the vast majority of production derived from the domesticated Eurasian species Vitis vinifera. Expansion of production into new areas, development of new cultivars, and concerns about adapting grapevines for changing climates necessitate the use of wild grapevine species in breeding programs. Diversity within Vitis has long been a topic of study; however, questions remain regarding relationships between species. Furthermore, the identity of some living accessions is unclear. METHODS: This study generated 11,020 single nucleotide polymorphism (SNP) markers for more than 300 accessions in the USDA-ARS grape germplasm repository using genotyping-by-sequencing. Resulting data sets were used to reconstruct evolutionary relationships among several North American and Eurasian Vitis species, and to suggest taxonomic labels for previously unidentified and misidentified germplasm accessions based on genetic distance. KEY RESULTS: Maximum likelihood analyses of SNP data support the monophyly of Vitis, subg. Vitis, a Eurasian subg. Vitis clade, and a North American subg. Vitis clade. Data delineate species groups within North America. In addition, analysis of genetic distance suggested taxonomic identities for 20 previously unidentified Vitis accessions and for 28 putatively misidentified accessions. CONCLUSIONS: This work advances understanding of Vitis evolutionary relationships and provides the foundation for ongoing germplasm enhancement. It supports conservation and breeding efforts by contributing to a growing genetic framework for identifying novel genetic variation and for incorporating new, unsampled populations into the germplasm repository system. PMID- 29578298 TI - Duration of propagule pressure affects non-native plant species abundances. AB - PREMISE OF THE STUDY: Invasions by non-native species are known to be related to present propagule pressure (e.g., the number of non-native seeds arriving in a site each year). However, previous studies have mostly ignored the potential effects of the length of time that a site has experienced propagule pressure. This study is novel in studying past as well as present propagule pressure and in demonstrating the importance of past propagule pressure. METHODS: We tested the importance of past and present propagule pressure in three plant communities in central Texas to quantify relationships between variables representing past and present propagule pressure, other environmental variables, and the abundance of non-native and native woody plant species. KEY RESULTS: Duration of propagule pressure predicted non-native species richness. Sites had greater non-native species richness if they were nearer to development (houses, roads) and if nearby development was older. While mesic woodlands had the most native species, streamside woodlands had the most non-native species. CONCLUSIONS: First, future studies of non-native invasions would benefit from including past as well as present propagule pressure. If past propagule pressure is not considered, its effects may be wrongly ascribed to present propagule pressure. Second, the non native species in this study are widely used in landscaping, and development age reflects the years that landscaping has been present nearby. As xeriscaping becomes more common, streamside woodlands may someday not have the highest non native species richness: the new drought-tolerant landscaping plants may be better invaders of drier sites than their predecessors.

AB - PURPOSE: The apical seal provided by a root canal filling may be breached via coronal leakage. This study aimed to compare the teeth restored with custom-made cast metal posts and cores cemented with different luting agents in terms of coronal microleakage after thermocycling. MATERIALS AND METHODS: This in vitro study was conducted on 32 extracted single-canal teeth. Root canals were prepared by step-back technique and filled with gutta percha and sealer. The coronal 7 mm of gutta percha was removed, and post space was prepared using peeso reamers #2 and #3 consecutively. After fabricating the acrylic resin patterns of the posts and cores, they were cast using Ni-Cr metal alloy. The specimens were divided into 4 groups in which the castings were cemented using one of the following luting agents: zinc phosphate (ZP), glass ionomer (GI), Panavia F 2.0, and Speed CEM. After cementation, the teeth were immersed in distilled water and incubated for 7 days. Then, the teeth were subjected to thermocycling, immersed in silver nitrate for 6 hours, and finally sectioned. The degree of dye penetration into the coronal part of the specimens was measured using a stereomicroscope. Data were analyzed using Kruskal-Wallis and Mann-Whitey U tests with significance level of 0.05. RESULTS: The median microleakage in ZP, Speed CEM, GI, and Panavia were 171.89, 114.76, 26.51, and 20.02 MUm, respectively. Pairwise comparisons among GI and ZP, GI, and Speed CEM, ZP and Panavia, ZP and Speed CEM, and Panavia and Speed CEM groups yielded significant differences (p < 0.05). CONCLUSION: Complete coronal seal was not achieved with any of the luting agents. The highest and the lowest degree of microleakage was yielded by ZP and Panavia luting agents, respectively.

PMID- 29578301 TI - Resveratrol Improves Muscle Atrophy by Modulating Mitochondrial Quality Control in STZ-Induced Diabetic Mice. AB - SCOPE: In this study, we aim to determine the effects of resveratrol (RSV) on muscle atrophy in streptozocin-induced diabetic mice and to explore mitochondrial quality control (MQC) as a possible mechanism. METHODS AND RESULTS: The experimental mice were fed either a control diet or an identical diet containing 0.04% RSV for 8 weeks. Examinations were subsequently carried out, including the effects of RSV on muscle atrophy and muscle function, as well as on the signaling pathways related to protein degradation and MQC processes. The results show that RSV supplementation improves muscle atrophy and muscle function, attenuates the increase in ubiquitin and muscle RING-finger protein-1 (MuRF-1), and simultaneously attenuates LC3-II and cleaved caspase-3 in the skeletal muscle of diabetic mice. Moreover, RSV treatment of diabetic mice results in an increase in mitochondrial biogenesis and inhibition of the activation of mitophagy in skeletal muscle. RSV also protects skeletal muscle against excess mitochondrial fusion and fission in the diabetic mice. CONCLUSION: The results suggest that RSV ameliorates diabetes-induced skeletal muscle atrophy by modulating MQC.

PMID- 29578305 TI - Yeast culture dietary supplementation modulates gut microbiota, growth and biochemical parameters of grass carp. AB - Gut microbiota contributes positively to the physiology of their host. Some feed additives have been suggested to improve livestock health and stimulate growth performance by modulating gut bacteria species. Here, we fed grass carp with 0 (control), 8% (Treat1), 10% (Treat2), 12% (Treat3) and 16% (Treat4) of yeast culture (YC) for 10 weeks. The gut microbiota was analysed by 16S rRNA gene V3-4 region via an Illumina MiSeq platform. PCoA test showed that gut bacterial communities in the control and Treat3 formed distinctly separate clusters. Although all the groups shared a large size of OTUs as a core microbiota community, a strong distinction existed at genus level. Treat3 contained the highest proportion of the beneficial bacteria and obviously enhanced the capacity of amino acid, lipid metabolism and digestive system. In addition, Treat3 significantly improved the fish growth and increased the liver and serum T-SOD activities while dramatically decreased the liver GPT and GOT. Collectively, these findings demonstrate the beneficial effects of YC feeding on gut microbiota, growth and biochemical parameters and Treat3 might be the optimal supplementation amount for grass carp, which opens up the possibility that a new feed additive can be developed for healthy aquaculture. PMID- 29578306 TI - A cytotoxicity, optical spectroscopy and computational binding analysis of 4-[3 acetyl-5-(acetylamino)-2-methyl-2,3-dihydro-1,3,4-thiadiazole-2-yl]phenyl benzoate in calf thymus DNA. AB - In this study the interaction mechanism between newly synthesized 4-(3-acetyl-5 (acetylamino)-2-methyl-2, 3-dihydro-1,3,4-thiadiazole-2-yl) phenyl benzoate (thiadiazole derivative) anticancer active drug with calf thymus DNA was investigated by using various optical spectroscopy techniques along with computational technique. The absorption spectrum shows a clear shift in the lower wavelength region, which may be due to strong hypochromic effect in the ctDNA and the drug. The results of steady state fluorescence spectroscopy show that there is static quenching occurring while increasing the thiadiazole drug concentration in the ethidium bromide-ctDNA system. Also the binding constant (K), thermo dynamical parameters of enthalpy change (DeltaH degrees ), entropy change (DeltaS degrees ) Gibbs free energy change (DeltaG degrees ) were calculated at different temperature (293 K, 298 K) and the results are in good agreement with theoretically calculated MMGBSA binding analysis. Time resolved emission spectroscopy analysis clearly explains the thiadiazole derivative competitive intercalation in the ethidium bromide-ctDNA system. Further, molecular docking studies was carried out to understand the hydrogen bonding and hydrophobic interaction between ctDNA and thiadiazole derivative molecule. In addition the docking and molecular dynamics charge distribution analysis was done to understand the internal stability of thiadiazole derivative drug binding sites of ctDNA. The global reactivity of thiadiazole derivative such as electronegativity, electrophilicity and chemical hardness has been calculated. PMID- 29578307 TI - Rapid and simultaneous quantification of a mixture of biopharmaceuticals by a liquid chromatography/quadrupole time-of-flight mass spectrometric method in rat plasma following cassette-dosing. AB - RATIONALE: The cassette-dosing technique is a technique that administers various drugs to a single animal at once and quantitated simultaneously. The purpose of this study was to evaluate the feasibility of cassette-dosing as a means of increasing throughput and decreasing animal usage for pharmacokinetic studies of biopharmaceuticals using liquid chromatography/time-of-flight mass spectrometric (LC/TOF-MS) analysis. METHODS: Brentuximab, trastuzumab, cetuximab and adalimumab were used as model biopharmaceuticals. The method consisted of immunoprecipitation followed by tryptic digestion for sample preparation and LC/TOF-MS analysis of specific signature peptides in the positive ion mode using electrospray ionization. The specific signature peptides used for quantification were from the complementarity-determining regions of each mAb. All rats received a single intravenous bolus injection containing either a single mAb or a mixture of four mAbs. RESULTS: The proposed method has been qualified in linearity range of 1-100 MUg/mL with correlation coefficients higher than 0.990. The qualification run met the acceptance criteria of +/-25% accuracy and precision values for quality control (QC) samples. This qualified LC/TOF-MS method was successfully applied to a pharmacokinetic study in the rat. The PK properties of mAbs administered as a cassette-dosage were similar to the pharmacokinetics of each antibody drug when administered as a single entity. CONCLUSIONS: These findings suggest that the cassette-dosing approach could be used to evaluate the PK properties of biopharmaceuticals in the early drug discovery stage. Also, this method would be useful for other preclinical sample analysis without developing new reagents for sample preparation.

AB - PURPOSE: Great progresses have been made for generating in vitro pluripotent stem cell pancreatic beta-like cells. However, the maturation stage of the cells still requires in vivo maturation to recreate the environmental niche. A deeper understanding of the factors promoting maturation of the cells is of great interest for clinical applications. EXPERIMENTAL DESIGN: Label-free mass spectrometry based proteomic analysis is performed on samples from a longitudinal study of differentiation of human induced pluripotent stem cells toward glucose responsive insulin producing cells. RESULTS: Proteome patterns correlate with specific transcription factor gene expression levels during in vitro differentiation, showing the relevance of the technology for identification of pancreatic-specific markers. The analysis of proteomes of the implanted cells in a longitudinal study shows that the neovascularization process linked to the extracellular matrix environment is time-dependent and conditions the proper maturation of the cells in beta-like cells secreting insulin in response to glucose. CONCLUSIONS AND CLINICAL RELEVANCE: Proteomic profiling is valuable to qualify and better understand in vivo maturation of progenitor cells toward beta cells. This is critical for future clinical trials where in vivo maturation still needs to be improved for robustness and effectiveness of cell therapy. Novel biomarkers for predicting the efficiency of maturation represents noninvasive monitoring tools for following efficiency of the implant. PMID- 29578311 TI - Correlates of toenail selenium and its cross-sectional association with metabolic syndrome. AB - BACKGROUND: The present study aimed to identify independent correlates of toenail selenium levels and to examine the association between toenail selenium levels and metabolic syndrome in Korean adults. METHODS: Cross-sectional analysis was conducted using baseline data from the Trace Element Study of Korean Adults in the Yeungnam area, an ongoing cohort study of Korean adults over the age of 35 years. The baseline survey consisted of questionnaires on demographics, lifestyle characteristics and medical information. Dietary information was obtained through a validated semi-quantitative food frequency questionnaire. Toenail selenium levels were quantified using neutron activation analysis. Biomarkers associated with metabolic syndrome were obtained from biennial medical check-ups. RESULTS: In the multivariable-adjusted analyses, independent lifestyle and dietary correlates of higher selenium levels were alcohol drinking (4.62% higher than nondrinking) and egg intake (0.43% higher per weekly serving), whereas current smoking (5.42% lower than nonsmoking) and vegetable consumption (0.05% lower per weekly serving) were associated with lower toenail selenium levels. In the multivariable adjusted logistic regression, no significant association was observed between toenail selenium levels and metabolic syndrome (odds ratio = 1.33, 95% confidence interval = 0.58-3.05). CONCLUSIONS: Multiple lifestyle and dietary factors influenced toenail selenium levels, although no meaningful association was observed between toenail selenium levels and metabolic syndrome in Korean adults. Future prospective large-scale cohort studies are required to determine whether there is a causal relationship between selenium levels and metabolic syndrome in Korean adults. PMID- 29578312 TI - Group-specific environmental sequencing reveals high levels of ecological heterogeneity across the microsporidian radiation. AB - The description of diversity is a key imperative in current biological studies and has been revolutionised by the molecular era that allows easy access to microbial diversity not visible to the naked eye. Broadly targeted SSU rRNA gene amplicon studies of diverse environmental habitats continue to reveal new microbial eukaryotic diversity. However, some eukaryotic lineages, particularly parasites, have divergent SSU sequences, and are therefore undersampled or excluded by the methodologies used for SSU studies. One such group is the Microsporidia, which have particularly divergent SSU sequences and are rarely detected in even large-scale amplicon studies. This is a serious omission as microsporidia are diverse and important parasites of humans and other animals of socio-economic importance. Whilst estimates of other microbial diversity are expanding, our knowledge of true microsporidian diversity has remained largely static. In this work, we have combined high throughput sequencing, broad environmental sampling and microsporidian-specific primers to broaden our understanding of the evolutionary diversity of the Microsporidia. Mapping our new sequences onto a tree of known microsporidian diversity we uncover new diversity across all areas of the microsporidian tree and uncover clades dominated by novel sequences, with no close described relatives. PMID- 29578313 TI - "In vitro" correction of the severe factor V deficiency-related coagulopathy by a novel plasma-derived factor V concentrate. AB - INTRODUCTION: Severe congenital factor V (FV) deficiency is a rare bleeding disorder characterized by very low/undetectable levels of FV. Fresh frozen plasma is the standard treatment for bleeding manifestations. Recently, a novel plasma derived FV concentrate has been developed. AIM: To evaluate the "in vitro" ability of the novel FV concentrate to normalize clotting times and generate normal amount of thrombin in plasma collected from patients with severe FV deficiency. METHODS: Prothrombin time (PT), activated partial thromboplastin time (aPTT), FV activity and antigen levels and thrombin generation were measured pre- and postspiking of plasma samples of 10 patients with increasing doses of FV concentrate (from 0 to 100 IU/dL). RESULTS: Prothrombin time and activated partial thromboplastin time ratios as well as all thrombin generation parameters were fully corrected by the addition of FV concentrate at a final concentration of 25 IU/dL. However, the addition of FV at a concentration of 1-3 IU/dL was already sufficient to correct peak height and endogenous thrombin potential (but not lag time and time to peak) after activation with 5 pmol/L tissue factor. FV activity and antigen levels showed a linear response to supplementation with the novel FV concentrate. CONCLUSION: The novel plasma-derived FV concentrate was effective to correct "in vitro" severe FV deficiency in patients. The optimal FV concentration to fully normalize both global clotting times and thrombin generation parameters using the novel plasma-derived FV concentrate was 25 IU/dL. PMID- 29578315 TI - Genes involved in stress response influence lithium efficacy in bipolar patients. AB - OBJECTIVES: In mood disorders, chronic stimulation with stress results in aberrant regulation of the hypothalamic-pituitary-adrenal (HPA) axis. Lithium was shown to influence HPA axis function. The underlying genetic background as well as environmental context may influence the stress response, and therefore lithium efficacy. The aim of the present study was to analyze if genetic variants located in genes involved in HPA axis regulation affect the response to long-term lithium treatment in bipolar patients. METHODS: We included 93 patients with bipolar disorder (32 males and 61 females), aged 31-80 years. The patients had been treated with lithium carbonate for at least 5 years. The magnitude of the lithium response was assessed using the Alda scale. Genotyping was performed for 28 polymorphisms in the genes encoding the following proteins involved in HPA axis regulation: corticotropin-releasing hormone receptor 1 (CRHR1), arginine vasopressin receptor 1B (AVPR1b), FK506 binding protein (FKBP) 5, FKBP4, BCL2 associated athanogene 1 (BAG1), stress induced phosphoprotein 1 (STIP1), glucocorticoid-induced transcript 1 (GLCC1), dual specificity phosphatase 1 (DUSP1) serine and arginine rich splicing factor (SRSF) 3, SRSF9, SRSF5, and acid phosphatase 1 (ACP1). Linkage disequilibrium and haplotype analysis were then performed, followed by statistical analysis (Statistica v.12; Stasoft, Krakow, Poland). RESULTS: We found a correlation between stressful life events at first episode and worse response to lithium (P=.019). In single marker analysis, we observed a significant association between three FKBP5 polymorphisms (rs1360780, rs7748266 and rs9296158), one ACP1 variant (rs300774) and one glucocorticoid induced transcript 1 gene (GLCC1) variant (rs37972) and the degree of lithium response. Five out of seven FKBP5 polymorphisms showed strong linkage with one haplotype demonstrating an association with lithium efficacy (P=.008). No relationship was found between the other analyzed polymorphisms and lithium response. CONCLUSION: The response to lithium may depend on the variants of genes regulating the HPA axis and stressful life events in bipolar patients.

PMID- 29578316 TI - Exploring Orthogonal Hydrogen Bonding towards Designing Organic-Salt-Based Supramolecular Gelators: Synthesis, Structures, and Anticancer Properties. AB - A series of primary ammonium monocarboxylate (PAM) salts derived from beta alanine derivatives of pyrene and naphthalene acetic acid, along with the parent acids, were explored to probe the plausible role of orthogonal hydrogen bonding resulting from amide???amide and PAM synthons on gelation. Single-crystal X-ray diffraction (SXRD) studies were performed on two parent acids and five PAM salts in the series. The data revealed that orthogonal hydrogen bonding played an important role in gelation. Structure-property correlation based on SXRD and powder X-ray diffraction data also supported the working hypothesis upon which these gelators were designed. 3-(4,5-Dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) and cell migration assay on a highly aggressive human breast cancer cell line, MDA-MB-231, revealed that one of the PAM salts in the series, namely, PAA.B2, displayed anticancer properties, and internalization of the gelator salt in the same cell line was confirmed by cell imaging. PMID- 29578317 TI - Least median of squares and iteratively re-weighted least squares as robust linear regression methods for fluorimetric determination of alpha-lipoic acid in capsules in ideal and non-ideal cases of linearity. AB - This study outlines two robust regression approaches, namely least median of squares (LMS) and iteratively re-weighted least squares (IRLS) to investigate their application in instrument analysis of nutraceuticals (that is, fluorescence quenching of merbromin reagent upon lipoic acid addition). These robust regression methods were used to calculate calibration data from the fluorescence quenching reaction (?F and F-ratio) under ideal or non-ideal linearity conditions. For each condition, data were treated using three regression fittings: Ordinary Least Squares (OLS), LMS and IRLS. Assessment of linearity, limits of detection (LOD) and quantitation (LOQ), accuracy and precision were carefully studied for each condition. LMS and IRLS regression line fittings showed significant improvement in correlation coefficients and all regression parameters for both methods and both conditions. In the ideal linearity condition, the intercept and slope changed insignificantly, but a dramatic change was observed for the non-ideal condition and linearity intercept. Under both linearity conditions, LOD and LOQ values after the robust regression line fitting of data were lower than those obtained before data treatment. The results obtained after statistical treatment indicated that the linearity ranges for drug determination could be expanded to lower limits of quantitation by enhancing the regression equation parameters after data treatment. Analysis results for lipoic acid in capsules, using both fluorimetric methods, treated by parametric OLS and after treatment by robust LMS and IRLS were compared for both linearity conditions.

AB - BACKGROUND: Endotoxin has been reported to be associated with chronic bronchitis or emphysema (CBE) at high occupational exposures. However, whether levels found in domestic environments have similar effects is unknown. OBJECTIVES: We aimed to study the association between house dust endotoxin and CBE in a sample representative of the U.S. population. METHODS: We analyzed data from 3,393 participants >=20 y old from the National Health and Nutrition Examination Survey (NHANES) 2005-2006. House dust from bedding and from bedroom floors was analyzed for endotoxin content. NHANES participants received questionnaires and underwent examination as well as extensive laboratory testing. Logistic regression was used to examine the association of endotoxin levels with CBE diagnosis and symptoms, adjusting for covariates. The survey design and weights were applied so that estimates were nationally representative and so that statistical inferences were made appropriately. RESULTS: The median endotoxin concentration in house dust was 14.61 EU/mg dust, and CBE was reported by 8.2% of participants. In the adjusted analysis, one unit (EU/mg) increase in log10-transformed endotoxin concentrations was associated with a 27% increase in the odds of CBE diagnosis [OR=1.27 (95% CI: 1.00, 1.61)] and a 78% increase in the odds of chronic bronchitis symptoms (defined as cough and phlegm for >=3 mo in a year for >=2 y) [OR=1.78 (95% CI: 1.01, 3.12)]. Sensitization to inhalant allergens (p=0.001) modified the relationship between endotoxin and CBE diagnosis, with stronger associations observed in sensitized participants [OR=2.46 (95% CI: 1.72, 3.50) for a unit increase in log10-endotoxin]. CONCLUSIONS: In a population-based sample of U.S. adults, endotoxin levels in homes were associated with a self-reported history of CBE diagnosis and chronic bronchitis symptoms, with stronger associations among people sensitized to inhalant allergens. https://doi.org/10.1289/EHP2452.

These heterogeneous phototransistors showed low persistence photocurrent compared with IGZO-only phototransistors and exhibited high photoresponsivity of 61 A/W, photosensitivity of 3.48 * 106, detectivity of 9.42 * 1010 Jones, external quantum efficiency of 154% in an optimized structure, and high photoresponsivity under water exposure via the deposition of silicon dioxide as a passivation layer. On the basis of these electrical results and various analyses, we determined that CH3NH3PbI3 could be activated as a light absorption layer, current barrier, and plasma damage blocking layer, which would serve to widen the range of applications of M-O-based optoelectronic devices with high photoresponsivity and reliability under visible light illumination. PMID- 29578325 TI - High-Sensitivity and Low-Power Flexible Schottky Hydrogen Sensor Based on Silicon Nanomembrane. AB - High-performance and low-power flexible Schottky diode-based hydrogen sensor was developed. The sensor was fabricated by releasing Si nanomembrane (SiNM) and transferring onto a plastic substrate. After the transfer, palladium (Pd) and aluminum (Al) were selectively deposited as a sensing material and an electrode, respectively. The top-down fabrication process of flexible Pd/SiNM diode H2 sensor is facile compared to other existing bottom-up fabricated flexible gas sensors while showing excellent H2 sensitivity (Delta I/ I0 > 700-0.5% H2 concentrations) and fast response time (tau10-90 = 22 s) at room temperature. In addition, selectivity, humidity, and mechanical tests verify that the sensor has excellent reliability and robustness under various environments. The operating power consumption of the sensor is only in the nanowatt range, which indicates its potential applications in low-power portable and wearable electronics.

AB - Three-dimensional (3D) orientations of individual anisotropic plasmonic nanoparticles in aggregates were observed in real time by integrated light sheet super-resolution microscopy ( iLSRM). Asymmetric light scattering of a gold nanorod (AuNR) was used to trigger signals based on the polarizer angle. Controlled photoswitching was achieved by turning the polarizer and obtaining a series of images at different polarization directions. 3D subdiffraction-limited super-resolution images were obtained by superlocalization of scattering signals as a function of the anisotropic optical properties of AuNRs. Varying the polarizer angle allowed resolution of the orientation of individual AuNRs. 3D images of individual nanoparticles were resolved in aggregated regions, resulting in as low as 64 nm axial resolution and 28 nm spatial resolution. The proposed imaging setup and localization approach demonstrates a convenient method for imaging under a noisy environment where the majority of scattering noise comes from cellular components. This integrated 3D iLSRM and localization technique was shown to be reliable and useful in the field of 3D nonfluorescence super resolution imaging.

AB - We describe the direct preparation of crystalline Ni3S2 thin films via atomic layer deposition (ALD) techniques at temperatures as low as 250 degrees C without postthermal treatments. A new ALD chemistry is proposed using bis(1 dimethylamino-2-methyl-2-butoxy) nickel(II) [Ni(dmamb)2] and H2S as precursors. Homogeneous and conformal depositions of Ni3S2 films were achieved on 4 in. wafers (both metal and oxide substrates, including Au and SiO2). The resulting crystalline Ni3S2 layers exhibited highly efficient and stable performance as electrocatalysts for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in alkaline solutions, with a low overpotential of 300 mV and a high turnover frequency for HER and an overpotential of 400 mV for OER (at a current density of 10 mA/cm2). Using our Ni3S2 films as both the cathode and the anode, two-electrode full-cell electrolyzers were constructed, which showed stable operation for 100 h at a current density of 10 mA/cm2. The proposed ALD electrocatalysts on planar surfaces exhibited the best performance among Ni3S2 materials for overall water splitting recorded to date. PMID- 29578329 TI - Temperature-Dependent and Gate-Tunable Rectification in a Black Phosphorus/WS2 van der Waals Heterojunction Diode. AB - Heterostructures comprising two-dimensional (2D) semiconductors fabricated by individual stacking exhibit interesting characteristics owing to their 2D nature and atomically sharp interface. As an emerging 2D material, black phosphorus (BP) nanosheets have drawn much attention because of their small band gap semiconductor characteristics along with high mobility. Stacking structures composed of p-type BP and n-type transition metal dichalcogenides can produce an atomically sharp interface with van der Waals interaction which leads to p-n diode functionality. In this study, for the first time, we fabricated a heterojunction p-n diode composed of BP and WS2. The rectification effects are examined for monolayer, bilayer, trilayer, and multilayer WS2 flakes in our BP/WS2 van der Waals heterojunction diodes and also verified by density function theory calculations. We report superior functionalities as compared to other van der Waals heterojunction, such as efficient gate-dependent static rectification of 2.6 * 104, temperature dependence, thickness dependence of rectification, and ideality factor of the device. The temperature dependence of Zener breakdown voltage and avalanche breakdown voltage were analyzed in the same device. Additionally, superior optoelectronic characteristics such as photoresponsivity of 500 mA/W and external quantum efficiency of 103% are achieved in the BP/WS2 van der Waals p-n diode, which is unprecedented for BP/transition metal dichalcogenides heterostructures. The BP/WS2 van der Waals p-n diodes have a profound potential to fabricate rectifiers, solar cells, and photovoltaic diodes in 2D semiconductor electronics and optoelectronics. PMID- 29578328 TI - Local Conduction in Mo xW1- xSe2: The Role of Stacking Faults, Defects, and Alloying. AB - Here, we report on the surface conductivity of WSe2 and Mo xW1- xSe2 (0 <= x <= 1) crystals investigated with conductive atomic force microscopy. We found that stacking faults, defects, and chemical heterogeneities form distinct two dimensional and one-dimensional conduction paths on the transition metal dichalcogenide surface. In the case of WSe2, in addition to step edges, we find a significant amount of stacking faults (formed during the cleaving process) that strongly influence the surface conductivity. These regions are attributed to the alternation of the 2H and 3R polytypism. The stacking faults form regular 2D patterns by alternation of the underlying stacking order, with a periodicity that varies significantly between different regions and samples. In the case of Mo xW1 xSe2, its conductivity has a localized nature, which depends on the underlying chemical composition and the Mo/W ratio. Segregation to W-rich and Mo-rich regions during the growth process leads to nonuniform conduction paths on the surface of the alloy. We found a gradual change of the conductivity moving from one region to the other, reminiscent of lateral band bending. Our results demonstrate the use of C-AFM as a nanoscopic tool to probe the electrical properties of largely inhomogeneous samples and show the complicated nature of the surface conductivity of TMDC alloys. PMID- 29578330 TI - FESTA: An Efficient Nuclear Magnetic Resonance Approach for the Structural Analysis of Mixtures Containing Fluorinated Species. AB - In complex mixtures, proton nuclear magnetic resonance (NMR) spectra are often very crowded, making spectral analysis complicated or even impossible, particularly when detailed structural information about the mixture components is needed. A new 1D NMR method (fluorine-edited selective TOCSY acquisition, FESTA) is introduced that facilitates the structural analysis of mixtures of species that contain fluorine. It allows simplified 1H spectra to be obtained that show only those protons that are in a spin system coupled to fluorine of interest. The new method is illustrated by factorizing a complex 1H spectrum into subspectra for individual spin systems involving different 19F sites. PMID- 29578331 TI - Disposable MoS2-Arrayed MALDI MS Chip for High-Throughput and Rapid Quantification of Sulfonamides in Multiple Real Samples. AB - In this work, we demonstrate, for the first time, the development of a disposable MoS2-arrayed matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) chip combined with an immunoaffinity enrichment method for high-throughput, rapid, and simultaneous quantitation of multiple sulfonamides (SAs). The disposable MALDI MS chip was designed and fabricated by MoS2 array formation on a commercial indium tin oxide (ITO) glass slide. A series of SAs were analyzed, and clear deprotonated signals were obtained in negative-ion mode. Compared with MoS2 arrayed commercial steel plate, the prepared MALDI MS chip exhibited comparable LDI efficiency, providing a good alternative and disposable substrate for MALDI MS analysis. Furthermore, internal standard (IS) was previously deposited onto the MoS2 array to simplify the experimental process for MALDI MS quantitation. 96 sample spots could be analyzed within 10 min in one single chip to perform quantitative analysis, recovery studies, and real foodstuff detection. Upon targeted extraction and enrichment by antibody conjugated magnetic beads, five SAs were quantitatively determined by the IS-first method with the linear range of 0.5-10 ng/mL ( R2 > 0.990). Good recoveries and repeatability were obtained for spiked pork, egg, and milk samples. SAs in several real foodstuffs were successfully identified and quantified. The developed method may provide a promising tool for the routine analysis of antibiotic residues in real samples. PMID- 29578332 TI - Turning Earth Abundant Kesterite-Based Solar Cells Into Efficient Protected Water Splitting Photocathodes. AB - CZTS/Se kesterite-based solar cells have been protected by conformal atomic layer deposition (ALD)-deposited TiO2 demonstrating its feasibility as powerful photocathodes for water splitting in highly acidic conditions (pH < 1), achieving stability with no detected degradation and with current density levels similar to photovoltaic productivities. The ALD has allowed low deposition temperatures of 200 degrees C for TiO2, preventing significant variations to the kesterite structure and CdS heterojunction, except for the pure-sulfide stoichiometry, which was studied by Raman spectroscopy. The measured photocurrent at 0 V vs reversible hydrogen electrode, 37 mA.cm-2, is the highest reported to date, and the associated half-cell solar-to-hydrogen efficiency reached 7%, being amongst the largest presented for kesterite-based photocathodes, corroborating the possibility of using them as abundant low-cost alternative photoabsorbers as their efficiencies are improved toward those of chalcopyrites. An electrical circuit has been proposed to model the photocathode, which comprises the photon absorption, charge transfer through the protective layer, and catalytic performance, which paves the way to the design of highly efficient photoelectrodes. PMID- 29578333 TI - Charged Residues in the C-Terminal Domain of Apolipoprotein A-I Modulate Oligomerization. AB - Charged residues of the C-terminal domain of human apolipoprotein A-I (apoA-I) were targeted by site-directed mutagenesis. A series of mutant proteins was engineered in which lysine residues (Lys 195, 206, 208, 226, 238, and 239) or glutamate residues (Glu 234 and 235) were replaced by glutamine. The amino acid substitutions did not result in changes in secondary structure content or protein stability. Cross-linking and size-exclusion chromatography showed that the mutations resulted in reduced self-association, generating a predominantly monomeric apoA-I when five or six lysine residues were substituted. The rate of phosphatidylcholine vesicle solubilization was enhanced for all variants, with approximately a threefold rate enhancement for apoA-I lacking Lys 206, 208, 238, and 239, or Glu 234 and 235. Single or double mutations did not change the ability to protect lipolyzed low density lipoprotein from aggregation, but variants lacking >4 lysine residues were less effective in preventing lipoprotein aggregation. ApoA-I mediated cellular lipid efflux from wild-type mice macrophage foam cells was decreased for the variant with five lysine mutations. However, this protein was more effective in releasing cellular phosphatidylcholine and sphingomyelin from Abca1-null mice macrophage foam cells. This suggests that the mutations caused changes in the interaction with ABCA1 transporters and that membrane microsolubilization was primarily responsible for lipid efflux in cells lacking ABCA1. Taken together, this study indicates that ionic interactions in the C-terminal domain of apoA-I favor self-association and that monomeric apoA-I is more active in solubilizing phospholipid bilayers. PMID- 29578334 TI - Cytidine Diphosphoramidate Kinase: An Enzyme Required for the Biosynthesis of the O-Methyl Phosphoramidate Modification in the Capsular Polysaccharides of Campylobacter jejuni. AB - Campylobacter jejuni, a leading cause of gastroenteritis, produces a capsular polysaccharide that is derivatized with a unique O-methyl phosphoramidate (MeOPN) modification. This modification contributes to serum resistance and invasion of epithelial cells. Previously, the first three biosynthetic steps for the formation of MeOPN were elucidated. The first step is catalyzed by a novel glutamine kinase (Cj1418), which catalyzes the adenosine triphosphate (ATP) dependent phosphorylation of the amide nitrogen of l-glutamine. l-Glutamine phosphate is used by cytidine triphosphate (CTP):phosphoglutamine cytidylyltransferase (Cj1416) to displace pyrophosphate from CTP to generate cytidine diphosphate (CDP)-l-glutamine, which is then hydrolyzed by gamma glutamyl-CDP-amidate hydrolase (Cj1417) to form cytidine diphosphoramidate (CDP NH2). Here, we show that Cj1415 catalyzes the ATP-dependent phosphorylation of CDP-NH2 to form 3'-phospho-cytidine-5'-diphosphoramidate. Cj1415 will also catalyze the phosphorylation of adenosine diphosphoramidate (ADP-NH2) and uridine diphosphoramidate (UDP-NH2) but at significantly reduced rates. It is proposed that Cj1415 be named cytidine diphosphoramidate kinase. PMID- 29578335 TI - Micropatterned 2D Hybrid Perovskite Thin Films with Enhanced Photoluminescence Lifetimes. AB - The application of luminescent materials in display screens and devices requires micropatterned structures. In this work, we have successfully printed microstructures of a two-dimensional (2D), orange-colored organic/inorganic hybrid perovskite ((C6H5CH2NH3)2PbI4) using two different soft lithography techniques. Notably, both techniques yield microstructures with very high aspect ratios in the range of 1.5-1.8. X-ray diffraction reveals a strong preferential orientation of the crystallites along the c-axis in both patterned structures, when compared to nonpatterned, drop-casted thin films. Furthermore, (time resolved) photoluminescence (PL) measurements reveal that the optical properties of (C6H5CH2NH3)2PbI4 are conserved upon patterning. We find that the larger grain sizes of the patterned films with respect to the nonpatterned film give rise to an enhanced PL lifetime. Thus, our results demonstrate easy and cost-effective ways to manufacture patterns of 2D organic/inorganic hybrid perovskites, while even improving their optical properties. This demonstrates the potential use of color-tunable 2D hybrids in optoelectronic devices. PMID- 29578336 TI - Structural Evidence for Rifampicin Monooxygenase Inactivating Rifampicin by Cleaving Its Ansa-Bridge. AB - Rifampicin monooxygenase (RIFMO) decreases the potency of rifampicin (RIF) by converting it to oxidative products. Further decomposition of RIF has been observed in bacteria producing RIFMO and contributes to RIFMO-mediated drug resistance. Here we report the first crystal structure of RIFMO in complex with the hydroxylated RIF product. The 2.10 A resolution structure reveals a breach of the ansa aliphatic chain of RIF between naphthoquinone C2 and amide N1. Our data suggest that RIFMO catalyzes the hydroxylation of RIF at the C2 atom followed by cleavage of the ansa linkage, which leads to inactivation of the antibiotic by preventing key contacts with the RNA polymerase target. PMID- 29578337 TI - Investigating the Effect of Bioirrigation on In Situ Porewater Concentrations and Fluxes of Polychlorinated Biphenyls Using Passive Samplers. AB - Polychlorinated biphenyl (PCB) fluxes from contaminated sediments can be caused by mechanisms including diffusion, bioirrigation, and resuspension, but it is often unclear which mechanisms are important. In the Lower Duwamish Waterway (Seattle, Washington), the presence of abundant benthic macrofauna suggests that porewater bioirrigation may be an important mechanism for PCB transport from the bed into the overlying water column. In this field study, the fluxes of PCBs due to bioirrigation were quantified by using (a) polyethylene (PE) samplers to quantify in situ and ex situ (i.e., equilibrium) PCB porewater concentration profiles and (b) measurements of the geochemical tracer 222Rn to quantify the rate of porewater exchange with overlying water. The results showed that bioirrigation caused sorptive disequilibrium with the surrounding sediment, which led to lower in situ porewater concentrations than expected from sediment concentrations. The combined fluxes of seven PCB congeners (Sigma7PCBs) were 1.6 26 ng/m2/day for the three field sites, similar in magnitude to the upper limit estimates of diffusive fluxes calculated assuming water-side boundary layer control (Sigma7PCBs = 1.3-47 ng/m2/day). Moreover, the depleted in situ porewater concentrations imply lower diffusive flux estimates than if the ex situ porewater concentrations had been used to estimate fluxes (Sigma7PCBs = 89-670 ng/m2/day). These results suggest that nondiffusive PCB fluxes from the sediment bed are occurring and that quantifying in situ porewater concentrations is crucial for accurately quantifying both diffusive and nondiffusive PCB fluxes. PMID- 29578338 TI - Exploration of the Kinetics of Toehold-Mediated Strand Displacement via Plasmon Rulers. AB - DNA/RNA strand displacement is one of the most fundamental reactions in DNA and RNA circuits and nanomachines. In this work, we reported an exploration of the dynamic process of the toehold-mediated strand displacement via core-satellite plasmon rulers at the single-molecule level. Applying plasmon rulers with unlimited lifetime, single-strand displacement triggered by the invader that resulted in stepwise leaving of satellite from the core was continuously monitored by changes of scattering signal for hours. The kinetics of strand displacement in vitro with three different toehold lengths have been investigated. Also, the study revealed the difference in the kinetics of strand displacement between DNA/RNA and DNA/DNA duplexes. For the kinetics study in vivo, influence from the surrounding medium has been evaluated using both phosphate buffer and cell lysate. Applying core-satellite plasmon rulers with high signal/noise ratio, kinetics study in living cells proceeded for the first time, which was not possible by conventional methods with a fluorescent reporter. The plasmon rulers, which are flexible, easily constructed, and robust, have proven to be effective tools in exploring the dynamical behaviors of biochemical reactions in vivo. PMID- 29578339 TI - CsFe4-deltaSe4: A Compound Closely Related to Alkali-Intercalated FeSe Superconductors. AB - We report the synthesis and characterizations of a new FeSe-based compound CsFe4 deltaSe4, which is closely related to alkali intercalated FeSe superconductors while exhibits distinct features. It does not undergo phase separation and antiferromagnetic transition. Powder neutron diffractions, electron microscopy and high-angle annular-dark-field images confirm that CsFe4-deltaSe4 possesses an ordered Cs arrangement as ?2 * ?2 superstructure, evidencing a B-centered orthorhombic lattice with a space group of Bmmm. The temperature-dependent powder neutron diffractions indicate no structural and magnetic transition from 320 to 5 K. In contrast to the symmetry-breaking in FeSe, this phase naturally possesses the orthorhombic symmetry even at room temperature. DFT calculations and transport measurements reveal a novel Fermi surface geometry with two electron like sheets centered on Gamma point and intermediate density of states at the Fermi level comparing with the value of FeSe and the superconducting A xFe2Se2. PMID- 29578340 TI - Base-Independent DNA Base-Excision Repair of 8-Oxoguanine. AB - Living organisms protect their genome from gene mutation by excising damaged DNA bases. Here, 8-oxoguanine (8OG) is one of the most abundant DNA lesions. In bacteria the base excision is catalyzed by the enzyme formamidopyrimidine-DNA- glycosylase (Fpg), for which two different orientations of 8OG binding into the active site of Fpg have been proposed: syn- and anti-conformation. Here, we present a new ribose-protonated repair mechanism for 8OG that is base-independent and can excise 8OG in both conformations. Using high-level QM/MM calculations with up to 588/573 atoms in the QM sphere, the activation barrier is computed in excellent agreement with the experimentally measured value. Since the excised base itself is not directly involved in the mechanism, this implies that lesion discrimination does not occur within the active site of the enzyme. PMID- 29578341 TI - Size-, Shape-, and Composition-Dependent Model for Metal Nanoparticle Stability Prediction. AB - Although tremendous applications for metal nanoparticles have been found in modern technologies, the understanding of their stability as related to morphology (size and shape) and chemical ordering (e.g., in bimetallics) remains limited. First-principles methods such as density functional theory (DFT) are capable of capturing accurate nanoalloy energetics; however, they are limited to very small nanoparticle sizes (<2 nm in diameter) due to their computational cost. Herein, we propose a bond-centric (BC) model able to capture cohesive energy trends over a range of monometallic and bimetallic nanoparticles and mixing behavior (excess energy) of nanoalloys, in great agreement with DFT calculations. We apply the BC model to screen the energetics of a recently reported 23 196-atom FePt nanoalloys ( Yang et al. Nature 2017 , 542 , 75 - 79 ), offering insights into both segregation and bulk-chemical ordering behavior. Because the BC model utilizes tabulated data (diatomic bond energies and bulk cohesive energies) and structural information on nanoparticles (coordination numbers), it can be applied to calculate the energetics of any nanoparticle morphology and chemical composition, thus significantly accelerating nanoalloy design.

AB - Species belonging to the genus Callicarpa are used traditionally in Chinese medicine for the treatment of inflammation, rheumatism, and pain. Investigation of the leaves and twigs of Callicarpa bodinieri resulted in the isolation of nine new abietane diterpenoids, bodinieric acids A-I (1-9), along with six known compounds (10-15). The structures of 1-9 were elucidated on the basis of the interpretation of their HRESIMS and NMR data and by ECD calculations. To explore the potential therapeutic target of this plant for immune-mediated disease, the inhibitory activities of the isolates obtained were determined against 13 kinase enzymes. Eight compounds exhibited moderate inhibitory effects on spleen tyrosine kinase (SYK), and the IC50 values of compounds 2 and 6 were 7.2 and 10.7 MUM, respectively. In addition, a preliminary structure-activity relationship of this scaffold was analyzed with both molecular docking and a 3D-QSAR pharmacophore model. PMID- 29578344 TI - Effects of High Acidity on Phase Transitions of an Organic Aerosol. AB - Aerosol particle morphology influences the effect of particles on climate. Recent studies have documented the high acidity found in many ambient aerosol particles. The effect of this acidity on the phase transitions of mixed organic/inorganic aerosol particles has not been addressed. To investigate this effect, six organic compounds and ammonium sulfate were investigated individually with varying amounts of sulfuric acid to determine the role of low pH in the separation, efflorescence, and deliquescence transitions. All phase transitions were affected by the addition of sulfuric acid. This effect was attributed primarily to the change in the identity of the inorganic component as the ammonium/sulfate ratio (ASR) was changed from 2 to 1.5 to 1. The separation relative humidity (SRH) decreased with increasing amounts of sulfuric acid for each system studied, with the largest effect seen in compounds that have a lower SRH when mixed with ammonium sulfate. Control studies without an inorganic salt revealed that for some systems, phase separation occurs for mixtures of sulfuric acid and an organic acid. Overall, it was found that for aerosol particles at low pH (<=0.35) composed of organic acids and inorganic salts, phase separation can be impeded in some cases.

AB - beta-Defensin 3 (BD3) was identified as a ligand for the melanocortin receptors (MCRs) in 2007, although the pharmacology activity of BD3 has not been clearly elucidated. Herein, it is demonstrated that human BD3 and mouse BD3 are full micromolar agonists at the MCRs. Furthermore, mouse beta-defensin 1 (BD1) and human BD1 are also MCR micromolar agonists. This work identifies BD1 as an endogenous MCR ligand and clarifies the controversial role of BD3 as a micromolar agonist. PMID- 29578345 TI - A Two-Step Procedure for the Overall Transamidation of 8-Aminoquinoline Amides Proceeding via the Intermediate N-Acyl-Boc-Carbamates. AB - Herein a two-step strategy for achieving overall transamidation of 8 aminoquinoline amides has been explored. In this protocol, the 8-aminoquinoline amides were first treated with Boc2O and DMAP to form the corresponding N-acyl Boc-carbamates, which were found to be sufficiently reactive to undergo subsequent aminolysis with different amines in the absence of any additional reagents or catalysts. To demonstrate the utility of this approach, it was applied on a number of 8-aminoquinoline amides from the recent C-H functionalization literature, enabling access to a range of elaborate amide derivatives in good to high yields. PMID- 29578346 TI - Wide-Range Near-Infrared Sensitizing 1 H-Benzo[ c, d]indol-2-ylidene-Based Squaraine Dyes for Dye-Sensitized Solar Cells. AB - NIR absorbing squaraine dyes SQ1-SQ7 having 1 H-benzo[ c, d]indol-2-ylidene as a donor moiety were designed for application in DSSCs. Annulation of the benzene ring to an 3 H-indolium-based anchor moiety led to a red-shifted and broadened absorption band on TiO2 film, which were reflected in the improved short-circuit current density of SQ2 (6.22 mA cm-2) compared to the nonbenzene fused derivative SQ1 (4.39 mA cm-2). Although the introduction of a butoxy (SQ4: 806 nm) or dialkylamino group (SQ5-SQ7: 815-820 nm) to the 1 H-benzo[ c, d]indol-2-ylidene based donor moiety resulted in red-shifted absorption maxima in ethanol compared to the nonsubstituted derivative SQ2 (784 nm), the HOMO energy level of SQ4-SQ7 gave rise to an undesirable approximation to the redox potential of I-/I3-. Thus, the butoxy (SQ4: 0.56) and dialkylamino (SQ5-SQ7: 0.25-0.30) derivatives had relatively lower conversion efficiencies. Since the 2-ethylhexyl derivative SQ3 exhibited red-shifted absorption (lambdamax: 796 nm), suitable HOMO and LUMO energy levels, and relatively efficient restriction of charge recombination, this dye achieved the highest conversion efficiency (1.31%), along with a high IPCE response of over 20% over a wide range from 640 to 860 nm and an onset of IPCE at 1000 nm. PMID- 29578348 TI - Gravitationally Driven Wicking for Enhanced Condensation Heat Transfer. AB - Vapor condensation is routinely used as an effective means of transferring heat or separating fluids. Filmwise condensation is prevalent in typical industrial scale systems, where the condensed fluid forms a thin liquid film due to the high surface energy associated with many industrial materials. Conversely, dropwise condensation, where the condensate forms discrete liquid droplets which grow, coalesce, and shed, results in an improvement in heat transfer performance of an order of magnitude compared to filmwise condensation. However, current state-of the-art dropwise technology relies on functional hydrophobic coatings, for example, long chain fatty acids or polymers, which are often not robust and therefore undesirable in industrial conditions. In addition, low surface tension fluid condensates, such as hydrocarbons, pose a unique challenge because common hydrophobic condenser coatings used to shed water (with a surface tension of 73 mN/m) often do not repel fluids with lower surface tensions (<25 mN/m). We demonstrate a method to enhance condensation heat transfer using gravitationally driven flow through a porous metal wick, which takes advantage of the condensate's affinity to wet the surface and also eliminates the need for condensate-phobic coatings. The condensate-filled wick has a lower thermal resistance than the fluid film observed during filmwise condensation, resulting in an improved heat transfer coefficient of up to an order of magnitude and comparable to that observed during dropwise condensation. The improved heat transfer realized by this design presents the opportunity for significant energy savings in natural gas processing, thermal management, heating and cooling, and power generation. PMID- 29578349 TI - Safety of propofol sedation directed by endoscopists: how long should we continue to generate evidence? AB - The administration of propofol by endoscopists is a source of permanent friction with the Societies of Anesthesiology, which is based more on a clear conflict of economic interest on the part of the anesthesiologists than supported by scientific evidence. Maestro Antolin et al. (1) presented a series of more than 33,000 sedations performed with propofol by endoscopists, observing a frequency of cardiorespiratory adverse events of 0.13%. Rather than confrontation between different specialties, where the corporatism of the Anesthesiology Societies and their interest in monopolizing the use of a safe drug such as propofol prevails with no scientific support, anesthesiologists, endoscopists and nurses should instead work together for the benefit of our patients. PMID- 29578347 TI - A Novel Orally Available Asthma Drug Candidate That Reduces Smooth Muscle Constriction and Inflammation by Targeting GABAA Receptors in the Lung. AB - We describe lead compound MIDD0301 for the oral treatment of asthma based on previously developed positive allosteric alpha5beta3gamma2 selective GABAA receptor (GABAAR) ligands. MIDD0301 relaxed airway smooth muscle at single micromolar concentrations as demonstrated with ex vivo guinea pig tracheal rings. MIDD0301 also attenuated airway hyperresponsiveness (AHR) in an ovalbumin murine model of asthma by oral administration. Reduced numbers of eosinophils and macrophages were observed in mouse bronchoalveolar lavage fluid without changing mucous metaplasia. Importantly, lung cytokine expression of IL-17A, IL-4, and TNF alpha were reduced for MIDD0301-treated mice without changing antiinflammatory cytokine IL-10 levels. Automated patch clamp confirmed amplification of GABA induced current mediated by alpha1-3,5beta3gamma2 GABAARs in the presence of MIDD0301. Pharmacodynamically, transmembrane currents of ex vivo CD4+ T cells from asthmatic mice were potentiated by MIDD0301 in the presence of GABA. The number of CD4+ T cells observed in the lung of MIDD0301-treated mice were reduced by an oral treatment of 20 mg/kg b.i.d. for 5 days. A half-life of almost 14 h was demonstrated by pharmacokinetic studies (PK) with no adverse CNS effects when treated mice were subjected to sensorimotor studies using the rotarod. PK studies also confirmed very low brain distribution. In conclusion, MIDD0301 represents a safe and improved oral asthma drug candidate that relaxes airway smooth muscle and attenuates inflammation in the lung leading to a reduction of AHR at a dosage lower than earlier reported GABAAR ligands. PMID- 29578351 TI - Endoscopy and sedation: an inseparable binomial for the gastroenterologist. AB - The development of endoscopy and its increasing demand among the population have led to a growing need for propofol-based sedation techniques. Benefit is indisputable for both patients and endoscopists, but some aspects require considering the "who" and "how" of sedation as related to safety and health care costs. Propofol is first-choice in endoscopy for the European Society of Gastrointestinal Endoscopy because of its fast onset of action and short half life, and many reports exist on its safety when used by gastroenterologists rather than anesthesiologists. In this issue of REED several originals support the efficiency and safety of propofol even for complex, high-risk, or protracted procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and enteroscopy. Propofol may be safely and effectively administered by a team with specific skills acquired through education and using a specific procedure. However, difficulties arise in real-world clinical practice that preclude such training, which in Spain should be included in the MIR (medico interno residente) specialization program curriculum. The Comision Nacional de Digestivo (Spanish National Commission on Digestive Diseases), sensitive to this training gap, has included in their latest version of the MIR program (under assessment) four additional competences, with number 145 (training in deep sedation) being most relevant here. In addition, the Spanish Society of Gastrointestinal Endoscopy (SEED) has invested significant efforts in sedation training, with over 50 courses on sedation for endoscopists and nurses. Continuing education and training in this field (for instance, refresher courses on advanced cardiopulmonary resuscitation) should be a goal for all endoscopy units. Because of the diversity found among hospitals, with single or multiple endoscopy rooms, efforts should be made to persuade those in charge of gastroenterology and anesthesiology departments to establish the necessary care circuits in order to guarantee patient safety by developing accurate protocols and promoting consensus among the scientific societies involved (Spanish Society for Digestive Diseases [SEPD], SEED and Spanish Society of Anaesthesiology, Resuscitation and Pain Management [SEDAR]) and their respective national commissions. PMID- 29578350 TI - Severe cardiorespiratory complications derived from propofol sedation monitored by an endoscopist. AB - INTRODUCTION: deep sedation with propofol monitored by an endoscopist in different endoscopy units is a controversial subject and the source of conflicts of interest between the various scientific societies of Anesthesiology and Gastroenterology. Many studies have already demonstrated the efficacy, efficiency and low incidence of complications associated with sedation when under the control of a trained endoscopist vs an anesthesiologist. MATERIAL AND METHODS: the rate of severe cardiorespiratory complications during various endoscopic examinations (gastroscopy, colonoscopy, endoscopic retrograde cholangiopancreatography [ERCP] and endoscopic ultrasound [EUS]) where sedation was controlled by an endoscopist within our unit, from 2011 to 2016, was reviewed. RESULTS: during the study period, 33,195 examinations were analyzed. The rate of cardiorespiratory complications was 0.13% and the majority were severe desaturations. Most cases responded to an opening in the airway associated with the interruption of drug infusion and an ambu bag was required in a few cases. There were no statistically significant differences between the different groups, except for mean age, risk by type of examination and ASA risk, where the difference between ERCP and the rest of examinations was statistically significant. CONCLUSION: there is a high level of evidence in the scientific literature suggesting that sedation controlled by a trained endoscopist is safe, effective and efficient. However, further prospective studies are required in order to confirm this conclusion due to the fact that the majority of studies to date are retrospective. PMID- 29578352 TI - Prospective study of the factors associated with poor tolerance to ambulatory colonoscopy under conscious sedation. AB - BACKGROUND: conscious sedation with benzodiazepines and opiates for colonoscopy is a widespread clinical practice. OBJECTIVE: to determine the patient's tolerance to colonoscopy and identify the factors associated with lower tolerance. METHODS: a prospective, single-center, descriptive study of patients undergoing ambulatory colonoscopy under conscious sedation. The pain was assessed using a visual analogue scale with a score of 0 to 100 and also qualitatively. RESULTS: three hundred patients with a median age of 54 years completed the study (p25-75: 45-64); 138 were men (46%). Tolerance was good in 273 cases (91%). The median value of tolerance was 13 (p25-p75: 4-33). Pain was considered as mild in 215 (71.7%), moderate in 57 (19%) and intense in 28 (9.3%). In the univariate study, greater pain was associated with females, anxiety, the indication for the procedure, the length of time and difficulty of the examination, and the doses of sedatives. In the multivariate study, both the indication (OR 2.92, 95% CI = 1.03 8.2, p < 0.05) and the difficulty of the examination (OR 4.68, 95% CI = 1.6-13.6, p < 0.01) were significant. Complications were found in 16 patients (5.3%), although all of them were insignificant. CONCLUSIONS: tolerance of patients undergoing ambulatory colonoscopy under conscious sedation is good in most cases and complications are infrequent and minor. A worse tolerance to the test is associated with women patients, individuals with anxiety prior to colonoscopy, indication, difficult and longer exploration and lower doses of sedatives. PMID- 29578353 TI - Barriers to diabetes awareness and self-help are influenced by people's demographics: perspectives of South Asians with type 2 diabetes. AB - AIM: To determine whether barriers to diabetes awareness and self-help differ in South Asian participants of different demographic characteristics (age, gender, and literacy) with type 2 diabetes living in the United Kingdom. METHODS: Six focus group discussions (FGDs) were carried out in patients who were categorized according to age (30-60 years, >=60 years), gender (male, female) and literacy status (literate, illiterate). Data were analysed following the iterative process of thematic analysis techniques. RESULTS: Barriers were demographic-specific. The illiterate groups reported language as the major barrier to improved diabetes awareness and self-help. The literate groups reported that information provided by healthcare providers was general, and not specific to their diet/culture. Major barriers to adherence to the recommended diet for diabetes included: insufficient knowledge/awareness about nutritional content of food (all groups); lack of self-will to resist eating sweets, especially during weddings/festivals (literate older groups/literate younger females/illiterate older males); difficulty cooking separate meals for diabetic and non-diabetic family members (illiterate/literate older females). Other barriers to seeking advice/help ranged from not wanting to disclose their diabetes as it may affect employment/work (literate groups) to fear of being singled out at social gatherings (illiterate groups). General lack of motivation to exercise was reported by all groups. Time constraints and not knowing what/how to exercise was reported by literate younger groups whilst the illiterate older groups reported to not having suitable exercising facilities at local communities. Different barriers were also reported when accessing healthcare; language barriers (illiterate groups), restricted access to doctors' appointments/difficulty attending specific appointment slots offered by General Practitioners (literate females). CONCLUSION: Different barriers exist to improved awareness about diabetes and self-help in different patient demographics. Lack of culturally appropriate diabetes educational/awareness programs in the community appeared to be a major barrier in most older and illiterate participants while younger participants reported time constraint. PMID- 29578354 TI - Considerations on accuracy, pattern and possible underlying factors of brain microbleed progression in older adults with absence or mild presence of vascular pathology. AB - Objective To analyse brain microbleed (BMB) progression, its possible underlying factors, and the influence of inter-observer differences, in older individuals with none or mild vascular pathology. Methods This study analysed magnetic resonance images, cognitive, demographic and laboratory data from all individuals from the Alzheimer's Disease (AD) Neuroimaging Initiative database who had the required sequences for identifying BMBs over three consecutive years at the time the database was accessed (January 2016). BMBs were assessed independently by two observers with similar levels of experience. Results A total of 291 patients were included in the study. The number of individuals with BMBs and the number of BMBs per individual slightly and nonsignificantly increased across three consecutive years (Y1: 55/291 [19%]; Y2: 61/291 [21%]; Y3: 66/291 [23%]) with 1-2 BMBs and (Y1: 11/291 [4%]; Y2: 12/291 [4%]; Y3: 14/291 [5%]) with >= 3 BMBs. Both observers identified a similar pattern of BMB prevalence and progression in each cognitive group (normal < early/late mild cognitive impairment (MCI) > AD patients) despite inter-observer differences (1.5 BMBs, 95% confidence interval 3.7, 6.2], kappa=0.543), which were mainly in the cortex. Serum cholesterol was the main predictor of change in BMB count between time-points but did not predict overall progression. Conclusions Inter-observer differences are always present and it is difficult to ascertain their influence in the analysis of BMB progression, which was observed in cognitively normal and MCI individuals, but not in AD patients. This should be confirmed in further studies. PMID- 29578355 TI - Risk factors for hypersensitivity reactions to tocilizumab introduction in systemic juvenile idiopathic arthritis. AB - OBJECTIVES: The objective of this study is to identify risk factors for hypersensitivity reaction (HSR) to tocilizumab (TCZ) in systemic juvenile idiopathic arthritis (sJIA). METHODS: Clinical records of 40 patients with sJIA administered TCZ at one center were retrospectively reviewed. Patients were divided into HSR or non-HSR groups depending on the presence of HSR between the first and third TCZ administrations; clinical and laboratory assessments, including serum cytokine profile, were compared. RESULTS: Five patients displayed HSR following the third TCZ administration. They were significantly younger, shorter, and lighter, with a higher peak body temperature than non-HSR patients following the third administration. Their serum C-reactive protein (CRP) level was undetectable following the first administration but detectable by the third administration. Before the third administration, the white blood cell counts and serum levels of CRP and sTNFRII were significantly higher in the HSR group than in the non-HSR group. The serum levels of interleukin-18 and -6 before the third TCZ administration were higher and lower than those before the first administration in the HSR and non-HSR groups, respectively. CONCLUSION: Patients with sJIA having a younger age, shorter stature, and lighter weight and those showing increased disease activity in the early period of TCZ administration may be at higher risk of TCZ-induced HSR.

AB - Pheochromocytoma is a rare catecholamine-secreting neoplasm that is the cause of hypertension in <0.2% of patients with hypertension. We encountered an unusual case of pheochromocytoma involving hematemesis and epistaxis episodes with accompanying hypertensive attacks. Venous ectasia was detected in the esophagus. Abdominal magnetic resonance imaging revealed an adenoma in the left adrenal region. The present case illustrates that pheochromocytoma can mimic different clinical conditions. PMID- 29578357 TI - African-American caregivers' perspectives on aggressive behaviors in dementia. AB - Purpose Although African-American dementia caregivers report less upset and more confidence managing aggressive behaviors when compared to whites, their contextual experience remains unclear and this study explores that context. Methods Semi-structured interviews with 13 African-American family caregivers were analyzed using content analysis. Results Two themes emerged, "It's the disease...not the person" and "You got to pick your battles." "It's the disease...not the person," reframing aggressive behavior, included three sub themes. Sometimes the person with dementia seemed like a stranger but caregivers remembered "In there somewhere is that person." Aggressive behavior made this perspective difficult as they reported, "Sometimes it's hard not to take it personal." Premorbid dyadic conflict made caregiving difficult but caregivers remembered they were "Not who they were then." "You got to pick your battles," reflecting cognitive and behavioral strategies, also included three sub-themes. Participants prioritized caregiving over other commitments by reminding themselves "I got to do what I gotta do." Preventing aggressive behaviors was most successful when "We didn't argue...we didn't insist" and caregivers remembered "Don't put her in a position to fail" when involving the person with dementia in activities. Implications African-American caregivers described substantial challenges when confronted by aggressive behaviors. Strategies employed by caregivers enabled them to maintain a caring perspective and the person with dementia to maintain calm. Interventions that help caregivers manage aggressive behaviors may benefit by considering the challenges, cultural values, and effective strategies used by African-Americans. PMID- 29578358 TI - Role of FcalphaR EC2 region in extracellular membrane localization. AB - The FcalphaR receptor (CD89) binds to the constant region of Immunoglobulin (Ig) A to mediate mucosal immunity [1-2]. FcalphaR consist of five exons: two that code for the signal peptide regions S1 & S2, two for the extracellular regions EC1 and EC2, and the final exon for the transmembrane/cytoplasmic tail region [3]. Previously, we reported that the EC1 region plays an essential role for extracellular membrane localization of the receptor [4], where the absence of EC1 would prevent the variants from localizing to the cell surface, even with a full signal peptide. In the case of FcalphaR Variant 4 (lacking the S2 region only), there was some "leakiness" to membrane surface localization. PMID- 29578359 TI - Approach to oligometastatic disease in head and neck cancer, on behalf of the GORTEC. AB - Median survival for recurrent/metastatic head and neck squamous cell cancer (HNSCC) patients is about 10 months after first-line best systemic treatment. We aimed to assess current approaches of oligometastatic HNSCC patients by the analysis of current concept and published data (1995-2017) in this population. Five-year survival rates are over 20% in selected patients who undergo metastasis directed therapy by either surgery or stereotactic irradiation. Human papillomavirus(+) HNSCC patients have more disseminated metastases but respond more favorably and also benefit from ablative treatments. Treatments of oligometastases are expanding rapidly. Unmet needs include revised imaging follow up strategies to detect metastases earlier, identification of predictive noninvasive biomarkers for treatment guidance, assessment and corrections of biases in current studies and randomized clinical trials. PMID- 29578360 TI - Efficacy and safety of interleukin-1 inhibitors in familial Mediterranean fever patients complicated with amyloidosis. AB - BACKGROUND: Colchicine is the mainstay of the treatment of familial Mediterranean fever (FMF). However, 10% of FMF patients do not respond well to colchicine. Efficacy of interleukin (IL)-1 inhibitors in reducing attacks have been demonstrated in colchicine-resistant FMF (crFMF) patients recently. Colchicine is still the only approved drug for the prevention of amyloidosis in FMF and utility of IL-1 inhibitors in crFMF cases who already has amyloidosis remain to be elucidated. Herein, we evaluated efficacy and safety of IL-1 inhibitors in patients with crFMF-associated AA amyloidosis in a relatively large single center study. METHODS: Medical records of FMF patients complicated with AA amyloidosis in our dedicated FMF center were retrospectively reviewed and those patients who ever treated with IL-1 inhibitors were enrolled into the study. Patient global, physician global assessments (on 0-10 cm visual analog scale), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum creatinine and 24-h urinary protein excretion values for each visit were recruited from computer-based hospital records. Treatment response of patients were assessed with clinical symptoms, serum albumin, CRP and ESR values. Renal outcome parameters were analyzed on those not receiving renal replacement therapy. RESULTS: Seventeen patients were identified with crFMF-amyloidosis that ever treated with IL-1 inhibitors. Background colchicine therapy was continued in all patients in maximal-tolerated dose along with IL-1 inhibitors. All patients benefit from IL-1 antagonists assessed by patient and physician global assessments. Inflammatory markers, CRP and ESR, were significantly reduced in all and normalized in 12 out of 17 patients. More importantly, the amount of proteinuria was remarkably improved following IL-1 inhibitor therapy (1606 mg/day to 519 mg/day, p = .008). Both anakinra and canakinumab were well-tolerated without severe side effects. All patients were initially treated with anakinra but switched to canakinumab in seven patients (one leukopenia, four injection site reaction, two inefficacy). CONCLUSION: We evaluated the clinical and laboratory responses to IL-1 inhibitors in crFMF-associated amyloidosis patients. We found significant decreases in CRP, ESR and proteinuria after IL-1 inhibitor therapy. This study confirmed that IL-1 inhibitors are effective for controlling attacks and inflammatory activity in FMF patients complicated with AA amyloidosis. Moreover, they reduce or stabilize amount of proteinuria and preserve renal function in short-term follow-up. Prolonged prospective clinical trials are warranted to assess their long-term efficacy in this particular patient group. PMID- 29578362 TI - Molecular aspects of hypercholesterolemia treatment: current perspectives and hopes. AB - Hypercholesterolemia is a pathological condition which has been reported in 39% of the worlds' adult population. We aimed to review molecular aspects of current and novel therapeutic approaches based on low-density lipoprotein cholesterol lowering strategies. Pathogenic mutations in the LDLR, ApoB, PCSK9 and LDLRAP genes cause deficient clearance of circulating low-density lipoprotein cholesterol particles via hepatic LDL receptor. This leads to increased plasma LDL cholesterol levels from birth, which can cause LDL depositions in the arterial walls. Ultimately, it progresses to atherosclerosis and an increased risk of premature cardiovascular diseases. Currently, statins, Ezetimibe, Bile acid sequestrants and PCSK9 inhibitors are the main therapeutic agents for the treatment of hypercholesterolemia. Moreover, novel RNA-based therapy had a strong impact on therapeutic strategies in recent decades. Additional development in understanding of the molecular basis of hypercholesterolemia will provide opportunities for the development of targeted therapy in the near future. Key Messages The most common genes involved in hypercholesterolemia are LDLR, PCSK9 and ApoB. Pharmacogenetic effects are typically constrained to pathways closely related to the pharmacodynamics and pharmacokinetics. Change in lifestyle and diet along with treatment of the underlying disease and drug therapy are the current therapeutic strategies. PMID- 29578361 TI - Immobilization of Trichoderma harzianum alpha-amylase on PPyAgNp/Fe3O4 nanocomposite: chemical and physical properties. AB - In this study, a new support has been developed by immobilization of alpha amylase onto modified magnetic Fe3O4-nanoparticles. The characterization of soluble and immobilized alpha-amylases with regards to kinetic parameters, pH, thermal stability and reusability was studied. The effect of polypyrrole/silver nanocomposite (PPyAgNp) percentage on weight of Fe3O4 and pH on the immobilization of alpha-amylase was studied. The highest immobilization efficiency (75%) was detected at 10% PPyAgNp/Fe3O4-nanocomposite and pH 7.0. Immobilization of alpha-amylase on PPyAgNp/Fe3O4-nanocomposite was characterized by FT-IR spectroscopy and scanning electron microscopy. The reusability of the immobilized enzyme activity was 80% of its initial activity after 10 reuses. The immobilized enzyme was more stable towards pH, temperature and metal ions compared with soluble enzyme. The kinetic study appeared higher affinity of immobilized enzyme (Km 2.5 mg starch) compared with soluble enzyme (Km 3.5 mg starch). In conclusion, the immobilization of alpha-amylase on PPyAgNp/Fe3O4 nanocomposite could successfully be used in industrial and medical applications. PMID- 29578363 TI - High prevalence of serum folate receptor autoantibodies in children with autism spectrum disorders. AB - BACKGROUND: Supplementation of folic acid by pregnant mothers is thought to lower the risk of autism spectrum disorders (ASDs) in the offspring. Folic acid is taken up by cells via receptors with high affinity for folate and reduced folic acid derivatives. However, this is blocked by the presence of folate receptor autoantibodies (FRAA). Cerebral FRAA have been detected with high frequency in children with ASDs, suggesting the existence of a link between folic acid uptake and disease aetiology. METHODS: We investigated the frequency of FRAA in serum samples from 40 children with ASDs and 42 gender- and age-matched children with typical development (TD). Serum FRAA concentrations were measured by enzyme linked immunosorbent assay. RESULTS: We found a significant difference in the frequency of serum FRAA in the two study cohorts. Serum FRAA were present in 77.5% (31/40) of children with ASDs compared with 54.8% (23/42) of TD children (p = 0.03746, Fischer's exact test). Thus, serum FRAA are more prevalent in children with ASDs than in TD children. CONCLUSIONS: Our data suggest that children with ASDs may have defects in folic acid absorption that play a role in the onset of ASDs.

PMID- 29578364 TI - Treatment of hepatocellular carcinoma: a cost analysis of yttrium-90 transarterial radioembolization versus sorafenib. AB - AIM: The aim was to evaluate cost-effectiveness of yttrium-90 transarterial radioembolization (TARE) in comparison to sorafenib treatment. PATIENTS & METHODS: A single-center, retrospective, observational study was performed, 166 patients with intermediate-/advanced-stage hepatocellular carcinoma were treated with sorafenib and 19 with TARE. The patients out of the sorafenib group matching the inclusion criteria for TARE, were reassigned to a subgroup SOR3. RESULTS: Mean costs for SOR3 patients amounted to ?27,992 per patient, instead for TARE treatment, mean expense per patient was ?17,761 (p = 0.028). Overall survival was similar between the two groups, while midterm survival rates (p = 0.012) were significantly higher with TARE treatment. CONCLUSION: TARE causes significantly lower treatment costs than sorafenib with better outcome in midterm survival. PMID- 29578365 TI - The Capicua tumor suppressor: a gatekeeper of Ras signaling in development and cancer. AB - The transcriptional repressor Capicua (CIC) has emerged as an important rheostat of cell growth regulated by RAS/MAPK signaling. Cic was originally discovered in Drosophila, where it was shown to be inactivated by MAPK signaling downstream of the RTKs Torso and EGFR, which results in signal-dependent responses that are required for normal cell fate specification, proliferation and survival of developing and adult tissues. CIC is highly conserved in mammals, where it is also negatively regulated by MAPK signaling. Here, we review the roles of CIC during mammalian development, tissue homeostasis, tumor formation and therapy resistance. Available data indicate that CIC is involved in multiple biological processes, including lung development, liver homeostasis, autoimmunity and neurobehavioral processes. Moreover, CIC has been shown to be involved in tumor development as a tumor suppressor, both in human as well as in mouse models. Finally, several lines of evidence implicate CIC as a determinant of sensitivity to EGFR and MAPK pathway inhibitors, suggesting that CIC may play a broader role in human cancer than originally anticipated. PMID- 29578367 TI - Incidence and survival in sinonasal carcinoma: a Danish population-based, nationwide study from 1980 to 2014. AB - BACKGROUND: Sinonasal cancers are rare and comprise <1% of all malignancies. This study describes incidence and survival in sinonasal carcinomas in Denmark from 1980 to 2014. METHODS: All patients registered in the Danish Cancer Registry in the period were included. Age-adjusted incidence rate, average annual percentage change, and relative survival were calculated. Age-period-cohort models were constructed. RESULTS: 1,720 patients with sinonasal carcinoma (median age 67 years, 63% males) were identified. There was no significant change in age adjusted incidence; 0.70 in 1980 to 0.43 per 100,000 in 2014 (p > .05). Relative 5- and 10-year survival were 52% and 40% for men, 58% and 42% for women. An increase in 5-year survival from 1980 to 2014 from 46% to 65% (p < .05) was found. Nasal carcinomas had a significantly better relative survival compared to sinus carcinoma, as did squamous cell carcinomas when compared to neuroendocrine malignancies. CONCLUSION: In Denmark between 1980 and 2014, the incidence of sinonasal carcinomas has been stable and the relative survival has increased significantly. PMID- 29578368 TI - Protective effects of banana pectin against aluminum-induced cognitive impairment and aluminum accumulation in mice. AB - To investigate the effect of pectin on absorption and bio-toxicity of aluminum, pectin extract (100 mg kg-1 d-1) from banana pulp was orally administrated to aluminum exposed mice (35 mg kg-1 d-1) for 6 weeks. Our result showed that body weight gain of the mice treated with aluminum plus banana pectin was 32.5% higher than that of mice exposed to aluminum alone after 6 weeks of the administration. In both the step-down inhibitory avoidance task and Morris water maze test, memory retention of aluminum-exposed mice was significantly improved by the pectin administration. Treatment with banana pectin effectively prevented absorption of aluminum from the gastrointestinal tract, total aluminum excretion of mice treated with banana pectin plus aluminum was 9.3% higher than that of mice exposed to aluminum alone on the 12th day. Aluminum level in serum, cerebrum, or cerebellum of mice treated with aluminum plus banana pectin was 30.8%, 17.5%, or 17.9% lower than that of mice exposed to aluminum alone on the 42nd day, respectively. In conclusion, banana pectin extract can effectively reduce aluminum toxicity in mice. PMID- 29578369 TI - Migration of metal clips into the duodenum after laparoscopic cholecystectomy: A report of two cases. AB - Migration of metal clips into the duodenum after laparoscopic cholecystectomy is rare. We herein present two cases of migration of metal clips into the duodenum in patients who developed upper quadrant discomfort and a poor appetite after laparoscopic cholecystectomy. Gastroscopy revealed metal clips in the duodenum. In one patient, the clip dropped from the duodenum after 2 months; the other patient went to another institution to undergo duodenotomy. The mechanism underlying migration of a metal clip into the duodenum remains unclear but might be related to chronic inflammation and duodenal peristalsis. In conclusion, clinicians must remember that metal clips can migrate after laparoscopic cholecystectomy and later cause complications. PMID- 29578371 TI - Extra View: Sirt1 Acts As A Gatekeeper Of Replication Initiation To Preserve Genomic Stability. AB - Since the discovery of a yeast gene silencing modifier (Silent Information Modifier 2, SIR2) and its role in maintaining genomic stability more than two decades ago, SIR2 homologs (sirtuins) were identified in diverse species. Sirtuins are protein deacetylases that play diverse roles in proper cellular metabolism including cell cycle progression and maintenance of genomic stability. In yeast, SIR2 interacts with replication origins and protein complexes that affect both replication origin usage and gene silencing. In metazoans, the largest SIR2 homolog, SIRT1, is implicated in epigenetic modifications, circadian signaling, DNA recombination and DNA repair. Until recently, very few studies investigated the role of mammalian SIRT1 in modulating DNA replication. We discuss a newly characterized interaction between human SIRT1 and the DNA replication machinery, reviewing data from recent studies that have investigated how complex signaling pathways that involve SIRT1 affect cellular growth regulatory circuits. PMID- 29578373 TI - Application of mindfulness-based stress reduction to a stress management intervention in a study of a mining sector company. AB - PURPOSE: The aim of this article was to check whether mindfulness-based stress reduction (MBSR) is an effective intervention in reducing work-related stress in the case of workers in a copper mine. METHODS: Sixty six employees were randomized to the experimental group (32 participants) or to the control group (34 participants). Work-related stress was measured using the job content questionnaire (JCQ) and mental health was measured using the general health questionnaire (GHQ-28) Experimental manipulation was 40-h MBSR training. RESULTS: Multivariate repeated-measures analysis of variance revealed a significant increase of JCQ decision latitude (F = 17.36, p < 0.001) and social support (supervisor F = 9.00, p < 0.004; coworker F = 5.61, p < 0.020), and a significant decrease in GHQ-28 anxiety (F = 5.28, p < 0.079) and depression (F = 3.95, p < 0.048) due to the intervention. CONCLUSIONS: The study confirms that MBSR can be effective in reducing stress resulting from the external risk (and/or imagined fear) of losing one's health or life. The use of MBSR could be recommended in health and safety activities in difficult and dangerous work conditions, such as mining, to promote workers' well-being. PMID- 29578370 TI - Lipodystrophic syndromes due to LMNA mutations: recent developments on biomolecular aspects, pathophysiological hypotheses and therapeutic perspectives. AB - Mutations in LMNA, encoding A-type lamins, are responsible for laminopathies including muscular dystrophies, lipodystrophies, and premature ageing syndromes. LMNA mutations have been shown to alter nuclear structure and stiffness, binding to partners at the nuclear envelope or within the nucleoplasm, gene expression and/or prelamin A maturation. LMNA-associated lipodystrophic features, combining generalized or partial fat atrophy and metabolic alterations associated with insulin resistance, could result from altered adipocyte differentiation or from altered fat structure. Recent studies shed some light on how pathogenic A-type lamin variants could trigger lipodystrophy, metabolic complications, and precocious cardiovascular events. Alterations in adipose tissue extracellular matrix and TGF-beta signaling could initiate metabolic inflexibility. Premature senescence of vascular cells could contribute to cardiovascular complications. In affected families, metabolic alterations occur at an earlier age across generations, which could result from epigenetic deregulation induced by LMNA mutations. Novel cellular models recapitulating adipogenic developmental pathways provide scalable tools for disease modeling and therapeutic screening. PMID- 29578372 TI - Optimization of mRNA untranslated regions for improved expression of therapeutic mRNA. AB - mRNA based therapies hold great promise for the treatment of genetic diseases. However, this therapeutic approach suffers from multiple challenges including the short half-life of exogenously administered mRNA and subsequent protein production. Modulation of untranslated regions (UTR) represents one approach to enhance both mRNA stability and translation efficiency. The current studies describe and validate screening methods using a diverse set of 5'UTR and 3'UTR combinations for improved expression of the Arginase 1 (ARG1) protein, a potential therapeutic mRNA target. Data revealed a number of critical aspects which need to be considered when developing a screening approach for engineering mRNA improvements. First, plasmid-based screening methods do not correlate with protein expression driven by exogenously expressed mRNA. Second, improved ARG1 protein production was driven by increased translation and not improved mRNA stability. Finally, the 5' UTR appears to be the key driver in protein expression for exogenously delivered mRNA. From the testing of the combinatorial library, the 5'UTR for complement factor 3 (C3) and cytochrome p4502E1 (CYP2E1) showed the largest and most consistent increase in protein expression relative to a reference UTR. Collectively, these data provide important information for the development and optimization of therapeutic mRNAs. PMID- 29578374 TI - Dancing Effects on Preschoolers' Sensorimotor Synchronization, Balance, and Movement Reaction Time. AB - In the present study, we compared an experimental group of preschool children ( n = 22; mean age = 5 years, 8 months) who followed an 8-week dance program with a control group ( n = 20; mean age = 5 years, 5 months) on pre-post measures of sensorimotor synchronization (K-Rhythm Test), balancing on one leg and movement reaction time. Compared with the control participants, the dance group demonstrated significantly better pretest to posttest improvements on sensorimotor synchronization and balance (but not movement reaction time). Considering the importance of sensorimotor synchronization and balance for subsequent child development and performance of daily and sport activities, these results suggest that dancing should be included in early childhood curricula. PMID- 29578375 TI - A kinematic comparison between long-line and cross-court top spin forehand in competitive table tennis players. AB - The aim of the present study was to compare the biomechanical characteristics of the table tennis top spin shot when played cross-court (CC) or long-line (LL) in competitive table tennis players. Seven national level players respectively completed 10 long-line and 10 cross-court top spin shots responding to a standard ball machine. A stereophotogrammetric system was used to track body segments while executing the motion. Significantly more flexed right knee and elbow angles were measured at the moment of maximum velocity of the racket (MMV) in LL. In addition, significantly greater angles between the feet and the table and between the shoulders and the table at the MMV, indicated more pronounced rotation angles of the lower upper and upper-body in LL compared to CC with respect to the table. A higher inclination of the racket at the MMV was found in LL. The elbow flexion and the racket inclination may be associated to the direction of the shot. The present findings show that kinematic differences exist between the LL and the CC topspin forehand in competitive table tennis players. Coaches should be aware of these differences to adopt the optimal teaching strategies and to reproduce proper joint angles during training. PMID- 29578376 TI - From 'automation' to 'autonomy': the importance of trust repair in human-machine interaction. AB - Modern interactions with technology are increasingly moving away from simple human use of computers as tools to the establishment of human relationships with autonomous entities that carry out actions on our behalf. In a recent commentary, Peter Hancock issued a stark warning to the field of human factors that attention must be focused on the appropriate design of a new class of technology: highly autonomous systems. In this article, we heed the warning and propose a human centred approach directly aimed at ensuring that future human-autonomy interactions remain focused on the user's needs and preferences. By adapting literature from industrial psychology, we propose a framework to infuse a unique human-like ability, building and actively repairing trust, into autonomous systems. We conclude by proposing a model to guide the design of future autonomy and a research agenda to explore current challenges in repairing trust between humans and autonomous systems. Practitioner Summary: This paper is a call to practitioners to re-cast our connection to technology as akin to a relationship between two humans rather than between a human and their tools. To that end, designing autonomy with trust repair abilities will ensure future technology maintains and repairs relationships with their human partners. PMID- 29578377 TI - Statement of Retraction. PMID- 29578378 TI - Preparation of high affinity antibody for ribavirin with new haptens and residue analysis in chicken muscle, eggs and duck muscle. AB - In this work, high affinity polyclonal antibodies for ribavirin (RBV) from new haptens were prepared and were used to analyse RBV residues in chicken muscle, eggs and duck muscle. The new haptens were synthesised with different spacers, and the best antibody was obtained with an IC50 value as low as 0.61 ng/mL in indirect competitive enzyme-linked immunosorbent assay (ELISA). The cross reactivities with another five antiviral drugs including amantadine, rimantadine, moroxydine, zanamivir and oseltamivir were less than 0.1%, which indicated the good specificity of the antibody. An ELISA was developed based on the antibody and applied to detect RBV in multi-food matrices. The sample preparation prior to detection only needed simple dilution after trichloroacetic acid extraction. The limits of detection were 1.07, 1.18 and 1.03 MUg/kg in chicken muscle, eggs and duck muscle, respectively. Recoveries ranged from 89.0% to 112.7% with coefficients of variation below 13.0%. Ten blind samples of chicken muscle were analysed simultaneously by ELISA and liquid chromatography-tandem mass spectrometry, and a good correlation between the methods was observed. The results indicated that the high affinity antibody could be applied for the simple and fast detection of RBV in multi-food matrices.

AB - Knee peak torque (PT) is associated to jump performance in volleyball players. It is not clear whether muscle strength imbalances of the knee joint can influence jump performance. The purpose of study was to analyse the association between PT and knee muscular imbalances with jump performance in professional volleyball players. Eleven elite male volleyball players (90.3 +/- 9.7 kg body mass and 1.94 +/- 0.06 m height) were evaluated in an isokinetic dynamometer at speeds of 60, 180 and 300 deg/s. Muscle strength imbalances were obtained through calculation of contralateral deficit between limbs and the conventional ratio (hamstrings/quadriceps). Countermovement jump (CMJ) was performed on a force plate to calculate mechanical power and height. Association was found between knee extensor PT at 180 deg/s with CMJ power (r = 0.610, p = 0.046). Conventional ratio at 300 deg/s showed negative association with CMJ (r = -0.656, p = 0.029). The optimal ratio between knee extensors PT in relation to the flexors PT is associated with the greater mechanical power in CMJ. Contralateral deficit does not seem to be associated with the CMJ performance. Considering the knee extensor PT is associated with CMJ power, our findings suggest that strength-based training in volleyball athletes should not omit the conventional muscle ratio. PMID- 29578380 TI - Time-motion analysis of goalball players in attacks: differences of the player positions and the throwing techniques. AB - In this study, we aimed to analyse goalball players time-motion variables (distance covered, time spent, maximum and average velocities) in official goalball match attacks, taking into account the attack phases (preparation and throwing), player position (centres and wings) and throwing techniques (frontal, spin and between the legs). A total of 365 attacks were assessed using a video based method (2D) through manual tracking using the Dvideo system. Inferential non-parametric statistics were applied for comparison of preparation vs. throwing phase, wings vs. centres and, among the throwing techniques, frontal, spin and between the legs. Significant differences were found between the attack preparation versus the throwing phase for all player time-motion variables: distance covered, time spent, maximum player velocity and average player velocity. Wing players performed most of the throws (85%) and covered longer distances than centres (1.65 vs 0.31 m). The between the legs and the spin throwing techniques presented greater values for most of the time-motion variables (distance covered, time spent and maximum player velocity) than did the frontal technique in both attack phases. These findings provide important information regarding players' movement patterns during goalball matches that can be used to plan more effective training. PMID- 29578381 TI - Stride length: the impact on propulsion and bracing ground reaction force in overhand throwing. AB - Propulsion and bracing ground reaction force (GRF) in overhand throwing are integral in propagating joint reaction kinetics and ball velocity, yet how stride length effects drive (hind) and stride (lead) leg GRF profiles remain unknown. Using a randomised crossover design, 19 pitchers (15 collegiate and 4 high school) were assigned to throw 2 simulated 80-pitch games at +/-25% of their desired stride length. An integrated motion capture system with two force plates and radar gun tracked each throw. Vertical and anterior-posterior GRF was normalised then impulse was derived. Paired t-tests identified whether differences between conditions were significant. Late in single leg support, peak propulsion GRF was statistically greater for the drive leg with increased stride. Stride leg peak vertical GRF in braking occurred before acceleration with longer strides, but near ball release with shorter strides. Greater posterior shear GRF involving both legs demonstrated increased braking with longer strides. Conversely, decreased drive leg propulsion reduced both legs' braking effects with shorter strides. Results suggest an interconnection between normalised stride length and GRF application in propulsion and bracing. This work has shown stride length to be an important kinematic factor affecting the magnitude and timing of external forces acting upon the body. PMID- 29578382 TI - Pre-operative screening for asymptomatic bacteriuria and associations with post operative outcomes in patients with spinal cord injury. AB - CONTEXT: Screening for asymptomatic bacteriuria (ASB) before non-urologic surgery is common but of unclear benefit. Our aim was to describe pre-operative ASB screening and post-operative outcomes in patients with neurogenic bladder due to spinal cord injury (SCI). METHODS: This was a descriptive retrospective cohort study of adults with SCI undergoing neurosurgical spine or orthopedic lower limb surgery from 10/1/2012-9/30/2014 at Veterans Affairs (VA) medical centers. National VA datasets and medical record review was used to describe frequency of pre-operative ASB screening, presence of ASB, and association with post-operative surgical site infection, urinary tract infection, and hospital readmission. RESULTS: 175 patients were included. Although over half of patients had pre operative ASB screening, only 30.8% actually had pre-operative ASB. 15.2% of patients screened were treated for ASB with antibiotics before surgery. Post operative urinary tract infection (UTI) or surgical site infection (SSI) occurred in 10 (5.7%) patients, and 20 patients (11.4%) were readmitted within 30 days. Neither ASB screening nor the presence of pre-operative ASB were associated with these post-op outcomes (p > 0.2 for all). CONCLUSION: Pre-operative ASB screening is common in patients with SCI undergoing elective spine and lower limb surgery, although ASB occurs in less than 1/3rd of cases. There were no associations between pre-operative ASB and outcomes. Further studies evaluating the clinical benefit of this practice in patients with SCI should be performed. PMID- 29578383 TI - Prevalence and associated factors of domestic violence among pregnant women attending routine antenatal care in Nepal. AB - AIMS: The primary aim of this study was to assess the prevalence of domestic violence (DV) and its associated factors among pregnant women in Nepal. The secondary aims were to investigate disclosure of DV by women to health-care personnel and to assess whether health-care personnel had asked women about their experience of DV. METHODS: This cross-sectional study included 2004 pregnant women between 12 and 28 weeks of gestation attending routine antenatal care at two hospitals in Nepal from August 2014 to November 2015. In this study, DV was defined as fear of a family member and/or an experience of physical, emotional or sexual violence. Associated risk factors were analysed using logistic regression analyses. RESULTS: Twenty-one per cent of the women had experienced DV; 12.5% experienced fear only, 3.6% violence only and 4.9% experienced both violence and fear. Less than 2% per cent reported physical violence during pregnancy. This study found that just 17.7% had ever been asked by health-care personnel about DV, and of the women who had reported DV, only 9.5% had disclosed their experience to health-care personnel. Women of young age and low socio-economic status were more likely to have experienced DV. Women who reported having their own income and the autonomy to use it were at significantly lower risk of DV compared to women with no income. CONCLUSIONS: A substantial proportion of women reported having experienced DV. Victims had rarely disclosed their experience of DV to health-care personnel. This study underlines the importance of integrating systematic assessment of DV in antenatal care. PMID- 29578384 TI - Start and turn performances of elite sprinters at the 2016 European Championships in swimming. AB - The aim of this study was to examine the performance characteristics of male and female finalists in the 100-m distance at the 2016 European Championships in swimming (long-course-metre). The performances of all 64 (32-males and 32 females) were analysed (8 swimmers per event; Freestyle, Backstroke, Breaststroke and Butterfly). A set of start and turn parameters were analysed. In the start main outcome, male swimmers were faster in Butterfly (5.71 +/- 0.14s) and females in Freestyle (6.68 +/- 0.28s). In the turn main outcome, male and female swimmers were faster in Freestyle (males: 9.55 +/- 0.13s; females: 10.78 +/- 0.28s). A significant and strong stroke effect was noted in the start and turn main outcome, in both sexes. In the start plus the turn combined, males and females were faster in Freestyle (males: 15.40 +/- 0.20s; females: 17.45 +/- 0.54s). The start and the turn combined accounted almost one-third of the total race time in all events, and non-significant differences (p > 0.05) were noted across the four swim strokes. Once this research made evident the high relevance of start and turns, it is suggested that coaches and swimmers should dedicate an expressive portion of the training perfecting these actions. PMID- 29578385 TI - Comparison of step-by-step kinematics of resisted, assisted and unloaded 20-m sprint runs. AB - This investigation examined step-by-step kinematics of sprint running acceleration. Using a randomised counterbalanced approach, 37 female team handball players (age 17.8 +/- 1.6 years, body mass 69.6 +/- 9.1 kg, height 1.74 +/- 0.06 m) performed resisted, assisted and unloaded 20-m sprints within a single session. 20-m sprint times and step velocity, as well as step length, step frequency, contact and flight times of each step were evaluated for each condition with a laser gun and an infrared mat. Almost all measured parameters were altered for each step under the resisted and assisted sprint conditions (eta2 >= 0.28). The exception was step frequency, which did not differ between assisted and normal sprints. Contact time, flight time and step frequency at almost each step were different between 'fast' vs. 'slow' sub-groups (eta2 >= 0.22). Nevertheless overall both groups responded similarly to the respective sprint conditions. No significant differences in step length were observed between groups for the respective condition. It is possible that continued exposure to assisted sprinting might allow the female team-sports players studied to adapt their coordination to the 'over-speed' condition and increase step frequency. It is notable that step-by-step kinematics in these sprints were easy to obtain using relatively inexpensive equipment with possibilities of direct feedback. PMID- 29578386 TI - The influence of spatial distribution on add-on therapy of designed Ca-Alg/CS MEMs system. AB - To improve the efficacy and reduce the systemic toxicity of the diabetes mellitus, herewith, we developed a novel microparticles-embedded microcapsules (MEMs) system, synthesized from calcium alginate/chitosan (Ca-Alg/CS), by emulsion gelation using a high voltage electrostatic droplet generator. In our study, we selected two antidiabetic drugs insulin (INS) and metformin (MET) as model drugs to investigate different spatial distribution appropriate of MEMs system. Characterization based on particle size and morphology, encapsulation efficiency and drug loading, as well as drug delivery properties were carried out on the MEMs system. Typical multi-chamber structure was shown by SEM and the optical spectra. The average diameters of microparticles and Ca-Alg/CS MEMs were 2100 nm and 410 MUm, respectively. Insulin and MET were embedded into MEMs via electrostatic reaction according to FT-IR spectra. Moreover, drug loading and encapsulation efficiency of INS were higher than that of MET in this system when drugs were loaded alone or together. More importantly, this system has potential for orderly drug release and well sustained release when MET in the inner and INS in the outer space could be applied as a combination therapy for diabetes. The obtained in vivo experimental data on diabetes rats has shown that the designed MEMs system resulted in a higher hypoglycemic effect within add-on therapy.

PMID- 29578387 TI - Identifying natural compounds as multi-target-directed ligands against Alzheimer's disease: an in silico approach. AB - Alzheimer's disease (AD) is a multi-factorial disease, which can be simply outlined as an irreversible and progressive neurodegenerative disorder with an unclear root cause. It is a major cause of dementia in old aged people. In the present study, utilizing the structural and biological activity information of ligands for five important and mostly studied vital targets (i.e. cyclin dependant kinase 5, beta-secretase, monoamine oxidase B, glycogen synthase kinase 3beta, acetylcholinesterase) that are believed to be effective against AD, we have developed five classification models using linear discriminant analysis (LDA) technique. Considering the importance of data curation, we have given more attention towards the chemical and biological data curation, which is a difficult task especially in case of big data-sets. Thus, to ease the curation process we have designed Konstanz Information Miner (KNIME) workflows, which are made available at http://teqip.jdvu.ac.in/QSAR_Tools/ . The developed models were appropriately validated based on the predictions for experiment derived data from test sets, as well as true external set compounds including known multi-target compounds. The domain of applicability for each classification model was checked based on a confidence estimation approach. Further, these validated models were employed for screening of natural compounds collected from the InterBioScreen natural database ( https://www.ibscreen.com/natural-compounds ). Further, the natural compounds that were categorized as 'actives' in at least two classification models out of five developed models were considered as multi target leads, and these compounds were further screened using the drug-like filter, molecular docking technique and then thoroughly analyzed using molecular dynamics studies. Finally, the most potential multi-target natural compounds against AD are suggested.

PMID- 29578393 TI - Prevalence and predictors of tricyclic antidepressant use among elderly Koreans in primary-care and specialty clinics. AB - OBJECTIVES: Tricyclic antidepressants (TCAs) are prescribed with caution in the elderly due to diverse side effects. We analyzed the patterns of TCA use in elderly patients in primary-care and specialty clinics and investigated factors influencing TCA prescriptions. MATERIALS AND METHODS: Elderly patients (>= 65 years old) prescribed antidepressants in primary-care clinics in 2013 were included from the Health Insurance Review and Assessment Service-Aged Patient Sample (HIRA-APS). Prevalence of TCA prescriptions was assessed by insurance coverage status, clinical specialty, and region. Multiple logistic regression analysis was performed to compute odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with TCA prescriptions. RESULTS: TCAs and selective serotonin reuptake inhibitors (SSRIs) comprised 45.2% and 15.0% of all antidepressant prescriptions, respectively. TCAs comprised 61.5% and 20.7% of antidepressant prescriptions for pain and depression, respectively. Patients aged >= 85 years were less likely to be treated with TCAs (OR 0.81, 95% CI 0.79 - 0.84) than those aged 65 - 69 years. The odds for being prescribed TCAs were higher for patients residing in cities (OR 1.20, 95% CI 1.18 - 1.23), treated in nonpsychiatric clinics (OR 5.64, 95% CI 5.53 - 5.76), and those covered by Veteran's Health (OR 1.62, 95% CI 1.37 - 1.90) when compared to patients residing in the Seoul metropolitan area, treated in psychiatric clinics, or covered by National Health Insurance, respectively. The prescriptions of TCAs with pain diagnoses were much higher than prescriptions for depression (OR 1.87, 95% CI 1.82 - 1.93). CONCLUSIONS: Compared with a 2005 report, the prevalence of TCA prescriptions in elderly patients in Korea has decreased substantially, but remains high. Various efforts should be considered to reduce TCA prescriptions in the elderly.?. PMID- 29578394 TI - Comparative efficacy and safety of TNF-inhibitor plus methotrexate versus oral triple therapy in patients with active rheumatoid arthritis inadequately responding to methotrexate: A meta-analysis of randomized controlled trials. AB - AIMS: The study aimed to assess the efficacy and safety of tumor necrosis factor inhibitor (TNFI) with methotrexate (MTX) vs. oral triple therapy in patients with active rheumatoid arthritis (RA), showing inadequate response to MTX. MATERIALS AND METHODS: We performed a meta-analysis of three randomized controlled trials (RCTs) (913 MTX-resistant RA patients) to examine the relative efficacy and safety of TNFI+MTX compared to triple therapy (hydroxychloroquine, sulfasalazine, MTX) in patients with RA responding inadequately to MTX. RESULTS: The American College of Rheumatology's 70% improvement (ACR70) response rate was significantly higher for TNFI+MTX-treated patients than for triple therapy-treated controls (RR 1.549, 95% confidence interval (CI) 1.087 - 2.207, p = 0.016). However, the ACR20 and ACR50 response rates did not differ between the TNFI+MTX group and the triple therapy group. The total Sharp score was significantly lower in TNFI+MTX-treated patients than in triple therapy-treated controls (SMD -0.173, 95% CI -0.301 to 0.045, p = 0.008). There was no significant difference related to the number of patients with serious adverse events between the TNFI+MTX group and the triple therapy group (RR 1.033, 95% CI 0.710 - 1.504, p = 0.864); however, TNFI+MTX resulted in higher infection rates than triple therapy (RR 1.513, 95% CI 1.149 - 1.992, p = 0.004). CONCLUSION: TNFI+MTX was found to be more effective than triple therapy in active RA patients inadequately responsive to MTX, but it is associated with a higher risk of infection.?.

PMID- 29578396 TI - Nephritis-associated plasmin receptor (NAPlr) positive glomerulonephritis caused by Aggregatibacter actinomycetemcomitans bacteremia: A case report. AB - Infection-related glomerulonephritis (IRGN) develops after various infections. It was previously thought to be caused by Streptococcus species alone but can also be caused by other pathogens. Nephritis-associated plasmin receptor (NAPlr) was discovered as a candidate nephritis-inducing factor in acute post-streptococcal glomerulonephritis. More recently, renal lesions caused by other pathogens were found to be positive for the same molecular marker. We report the case of a 64 year-old man who experienced repeated fever for several months and presented with progressively-deteriorating renal function. He had previously undergone aortic valve replacement. Aggregatibacter actinomycetemcomitans, a component of the oral flora, was detected in a blood culture. Renal biopsy showed diffuse proliferative glomerulonephritis. Immunofluorescence staining of the kidney specimen was positive for immunoglobulins, complements, and NAPlr. The patient was diagnosed with infectious endocarditis and IRGN. Six weeks of intravenous antibiotic therapy improved the patient's clinical condition and kidney function. In this case, IRGN was caused by a rare pathogen. This is the first published case to show NAPlr positivity in the glomeruli after systemic infection with the periodontal bacteria, Aggregatibacter actinomycetemcomitans. This case and subsequent research might expand the concept of IRGN, anchored by NAPlr as a key diagnostic biomarker.?. PMID- 29578397 TI - Fibrillary glomerulonephritis in an HIV patient without concurrent hepatitis C infection: Case report and review of the literature?. AB - The most common renal disease associated with human immunodeficiency virus infection (HIV) is HIV-associated nephropathy (HIVAN), especially in the African American patient population. However, various patterns of glomerulonephritis (GN) are not uncommon, collectively accounting for nearly half of the renal biopsies performed in HIV patients. Most GNs that occur in HIV patients are immune complex mediated, often with concurrent infections such as hepatitis B or C. Fibrillary glomerulonephritis (FGN), a rare primary glomerular disease, has only been reported in 2 HIV patients, and both patients had concurrent hepatitis C (HCV) infection. Here we report a unique case of FGN with unusual ultrastructural morphology in an HIV-positive African American patient without concurrent HCV infection. The patient presented with nephrotic range proteinuria and renal insufficiency. A percutaneous kidney biopsy showed mesangial and segmental endocapillary proliferative GN with crescent formation. Immunofluorescence studies revealed IgG-, kappa-, and C3-positive deposits in the mesangium and capillary loops. Electron microscopy demonstrated diagnostic features of FGN: randomly-arranged fibrillary deposits with a diameter of 15 - 30 nm. The deposits had an unusual distribution pattern of hump-like large deposits on the subepithelial aspect. Additionally, smaller deposits were also present in the mesangium. To our knowledge, this is the first reported case of FGN in an HIV patient without concurrent HCV infection.?. PMID- 29578398 TI - Variability of serum phosphorus and its association with mortality among hemodialysis patients?. AB - OBJECTIVE: To determine the relationship between the variability of serum phosphorus and mortality among maintenance hemodialysis (MHD) patients. MATERIALS AND METHODS: A total of 502 MHD cases were studied from the Shanghai Renal Registry Network. Serum phosphorus variability was indicated by a coefficient of variation (CV). According to the CV median of serum phosphorus, patients were divided into two groups: a high-variability group (CV >= 0.226 mmol/L) and a low variability group (CV < 0.226 mmol/L). Average phosphorus <= 1.78 mmol/L was defined as the standard phosphorus group and serum phosphorus > 1.78 mmol/L was defined as the non-standard phosphorus group. The relationship between serum phosphorus variability and all-cause and cardiovascular disease (CVD) mortality was assessed. RESULTS: In the 502 MHD cases, the average age of patients was 63.9 +/- 14.60 years, and dialysis vintage was 82.0 (43.0 - 139.0) months. 118 patients (23.5%) died, succumbing to all-cause mortality, while 64 patients (14.3%) died from CVD. The high-variability group had increased all-cause mortality (27.7% vs. 19.3%, p = 0.028). Death from CVD was increased in the high variability group, but had no statistical significance (15.4% vs. 10.0%, p = 0.082). Cox regression analysis showed that older age, low hemoglobin levels, a higher phosphorus CV, and low serum albumin were independent risk factors for all cause and CVD mortality. The standard group with low-phosphorus variability had a decreased mortality compared with the non-standard group with high variability (15.3 vs. 29.2%, p = 0.047 and 6.0 vs. 15.0%, p = 0.033, respectively). The Kaplan-Meier method revealed that patients with low phosphorus variability had a decreased all-cause and CVD mortality (p = 0.023 and p = 0.047, respectively) compared with high phosphorus variability patients. CONCLUSION: Higher phosphorus CV was independently correlated with all-cause and CVD mortality. Low phosphorus variability with on-target levels resulted in decreased patient mortality. Thus, stable serum phosphorus levels may improve survival in MHD patients.?. PMID- 29578399 TI - Mini-review of kidney disease following hematopoietic stem cell transplant?. AB - Advancements in hematopoietic cell transplantation (HCT) have broadened indications for its use and resulted in more long-term survivors. Stem cell transplantation is associated with several well-known toxicities, although renal complications are not well defined. Acute and chronic kidney disease remains a common complication following transplantation itself. Incidence and risk factors for the development of chronic kidney disease (CKD) is less well understood. Recent estimates suggest that nearly 15% of subjects undergoing HCT will develop CKD, a complication that can progress to end-stage renal disease (ESRD), disrupts overall quality of life, and reduces overall survival. Several commonly-reported risk factors include acute kidney injury, graft-versus-host disease, and long term calcineurin inhibitor use. This review highlights the incidence, timeline, etiology, risk factors, and prognosis of kidney disease in the setting of hematopoietic stem cell transplantation. Investigation of the causes of CKD is needed, as are ways to prevent, mitigate, and treat kidney injury. Renal disease importantly reflects prognosis, with dialysis-requiring patients carrying greater than 80% mortality after 3 years. Although CKD following HCT is common, prospective studies are needed to confirm risk factors and better define the underlying mechanisms in order to promote therapies that prevent this complication.?. PMID- 29578400 TI - Incidence and timing of inadvertent nephrostomy catheter displacement in patients with ureteral obstruction?. AB - INTRODUCTION: To evaluate nephrostomy catheter displacement, we assessed the cumulative nephrostomy catheter displacement rate in patients with percutaneous nephrostomy and compared the nephrostomy displacement rates between pigtail and balloon catheters. MATERIALS AND METHODS: Between 2003 and 2011, 87 patients who underwent percutaneous nephrostomy catheter placement and more than one subsequent catheter replacement were retrospectively identified. We evaluated their inadvertent nephrostomy catheter displacement. RESULTS: 20 patients (23.0%) experienced incidental nephrostomy catheter displacement during the follow-up period. Kaplan-Meier analysis revealed that the 1-year nephrostomy catheter displacement-free survival rate was 62 +/- 9%. No significant independent risk factors for predicting nephrostomy catheter displacement were identified, including the type of catheter. The median time from initial placement to displacement of pigtail catheters was shorter than that of balloon catheters. CONCLUSION: There were no significant differences in the nephrostomy catheter displacement-free survival rates between the two types of catheters. Regardless of the type of catheter, our results indicated that careful handling and guiding during catheter placement are important for all patients because of the high risk of inadvertent events.?. PMID- 29578401 TI - Association between preoperative renin-angiotensin system inhibitor use and postoperative acute kidney injury risk in patients with hypertension?. AB - PURPOSE: To determine whether preoperative renin-angiotensin system (RAS) inhibitor use within 7 days of noncardiac surgery is associated with a lower incidence of postoperative acute kidney injury (AKI) in hypertensive patients. MATERIALS AND METHODS: We retrospectively analyzed 12,545 hypertensive patients undergoing noncardiac surgery at the Third Xiangya Hospital of Central South University from February 2007 to November 2015. According to the use of RAS inhibitors within 7 days of surgery, the patients were divided into a RASI group and a non-RASI group. We used a multivariable logistic regression model and propensity score matching (PSM) analysis to examine the association between preoperative RAS inhibitor use and postoperative AKI incidence. RESULTS: Among the 12,545 hypertensive patients undergoing noncardiac surgery who met the inclusion/exclusion criteria, 18.74% received preoperative RAS inhibitor treatment within 7 days of surgery. After PSM, 2,192 patients in each group were matched successfully. The incidence of postoperative AKI in the RASI group was significantly lower than that in the non-RASI group (7.39% vs. 12.32%, p < 0.001). The multivariable logistic regression analysis and the PSM analysis demonstrated similar associations between preoperative RAS inhibitor use and postoperative AKI incidence. This association was modified by the presence of preoperative congestive heart failure (CHF) (p-value for the interaction: 0.027), and the observed association was not evident in patients without CHF (CHF: adjusted odds ratios (ORs): 0.47; 95% CI: 0.31 - 0.70 vs. no CHF: adjusted OR: 0.80; 95% CI: 0.62 - 1.03). CONCLUSION: The preoperative use of RAS inhibitors in hypertensive patients was associated with a lower incidence of AKI following noncardiac surgery, and this association was not significant in the subgroup population without CHF.?. PMID- 29578402 TI - Chemotherapeutic agents eligible for prior dosing in pancreatic cancer patients requiring hemodialysis: a systematic review?. AB - AIMS: New chemotherapeutic agents prolong survival of patients with pancreatic ductal adenocarcinoma (PDAC). Although their incidence is rising, patients with end-stage renal disease (ESRD) requiring hemodialysis (HD) are not included in the phase III trials evaluating the effects of these chemotherapies. Many experts recommend applying chemotherapy after HD using a reduced dose. Alternatively, the concept of prior dosing allows for the application of dialyzable chemotherapeutic drugs using a normal dose, with an HD followed shortly after to mimic normal renal function. In this work, we provide guidance for clinicians on how to use chemotherapy in patients with PDAC on HD and how to identify substances suitable for prior dosing. MATERIALS AND METHODS: We systematically searched PubMed, from inception to September 2016, for published studies describing patients with ESRD on HD who received chemotherapies commonly applied in PDAC, including gemcitabine, fluorouracil (5-FU), capecitabine, oxaliplatin, irinotecan, docetaxel, erlotinib, sunitinib, S-1, and afatinib. Applied dosages, described toxicities, application time relative to HD, and pharmacokinetic measurements of the drug and its metabolites were assessed. Quantitative analysis of the drug plasma concentrations, including half-life during and in between HD and fraction of the drug eliminated during HD, were assessed. RESULTS: We identified 56 studies describing 128 patients with ESRD undergoing HD during chemotherapeutic treatment. Quantitative pharmacokinetic analysis revealed that the following substances are dialyzable and thus suitable for application using the prior dosing method: gemcitabine, 5-FU, oxaliplatin, irinotecan, and S-1. CONCLUSION: This work supports the application of dialyzable chemotherapeutic agents in patients with PDAC in standard dose when HD is performed shortly after the infusion.?. PMID- 29578403 TI - Patient-reported outcomes (PROs) argue against the limited use of peritoneal dialysis in end-stage renal disease?. AB - AIM: Approximately 40% of dialysis patients are durably treated with peritoneal dialysis (PD) in our teaching hospital. Patients' perspectives were studied by patient-reported outcome measurements (PROMs) to find possible explanations for why the generally-reported decline in the use of PD hardly occurred in our facility. MATERIALS AND METHODS: All 75 prevalent adult dialysis patients hemodialysis (HD) duration 27, PD 16 months) were included. All had received predialysis care and education for > 6 month. Cross-sectional sociodemographic and clinical data, SF-36, KDQOL-SF, and predialysis anxiety/depression scores were collected in February 2016. Differences in PROMs between PD and HD patients were analyzed. RESULTS: Despite more comorbidity in the PD population, generally used dialysis parameters were adequate and similar between HD (n = 42) and PD (n = 33) patients as was annual mortality. Many factors associated with a predialysis modality choice for PD were absent. A higher anxiety/depression score was found in pre-HD compared to pre-PD patients. PROMs were returned by 97%. PD patients performed better on a number of PROMs than their HD counterparts. CONCLUSION: This single-center cross-section with a modest number of patients but an almost 100% patient response shows that having 40% of patients on PD is possible with excellent results in terms of patient-reported outcomes. A structured patient education with attention to personal needs of patients, an adequate infrastructure for PD, and a dedicated team with ongoing patient support are key factors. Sharing best practices may help to slow down or even reverse the decline of PD, which is a pity both for patients and society.?. PMID- 29578404 TI - Priapism and hemodialysis: Case report and literature review?. AB - BACKGROUND: Priapism is a known but rarely described complication of patients on dialysis. The incidence of priapism in the general population is estimated at 1.5 in 100,000 patients and 2.9 in 100,000 patients in males over 40 years of age; however there is little current literature describing priapism in adult dialysis patients and no current literature in pediatric dialysis patients [1]. We describe two pediatric patients who developed priapism concurrent with hemodialysis, each with differing severity and therapeutic management. Case diagnosis/treatment: Two adolescent males presented with painful erection during a chronic hemodialysis treatment. Patient 1 required urologic intervention for management and treatment. Further medical treatment subsequently led to pseudoephedrine intoxication which self-resolved. Patient 2's priapism course self-resolved with adjustment in hemoglobin targets and did not require further surgical or medical intervention. Neither had recurrent episodes of priapism with careful management to maintain hemoglobin levels between 11 and 12 g/dL. CONCLUSION: Priapism is a rarely reported complication of dialysis in adult patients and has not been described in pediatric dialysis patients. The etiology remains unclear but is hypothesized to be multifactorial including heparin associated effects and epoetin administration. In our patients, commonality between the two included presumed high androgen levels (given age) and borderline to high hemoglobin levels in patients receiving epoetin alfa. This in combination with prior studies highlights the possible role epoetin administration may play. The role of heparin remains a possibility but is unclear. Further studies are needed to more clearly elucidate the etiology.?. PMID- 29578405 TI - NOTCH activity differentially affects alternative cell fate acquisition and maintenance. AB - The pituitary is an essential endocrine gland regulating multiple processes. Regeneration of endocrine cells is of therapeutic interest and recent studies are promising, but mechanisms of endocrine cell fate acquisition need to be better characterised. The NOTCH pathway is important during pituitary development. Here, we further characterise its role in the murine pituitary, revealing differential sensitivity within and between lineages. In progenitors, NOTCH activation blocks cell fate acquisition, with time-dependant modulation. In differentiating cells, response to activation is blunted in the POU1F1 lineage, with apparently normal cell fate specification, while POMC cells remain sensitive. Absence of apparent defects in Pou1f1-Cre; Rbpjfl/fl mice further suggests no direct role for NOTCH signalling in POU1F1 cell fate acquisition. In contrast, in the POMC lineage, NICD expression induces a regression towards a progenitor-like state, suggesting that the NOTCH pathway specifically blocks POMC cell differentiation. These results have implications for pituitary development, plasticity and regeneration. Activation of NOTCH signalling in different cell lineages of the embryonic murine pituitary uncovers an unexpected differential sensitivity, and this consequently reveals new aspects of endocrine lineages development and plasticity.

AB - Retinal vessel changes and retinal whitening, distinctive features of malarial retinopathy, can be directly observed during routine eye examination in children with P. falciparum cerebral malaria. We investigated their clinical significance and underlying mechanisms through linked clinical, clinicopathological and image analysis studies. Orange vessels and severe foveal whitening (clinical examination, n = 817, OR, 95% CI: 2.90, 1.96-4.30; 3.4, 1.8-6.3, both p<0.001), and arteriolar involvement by intravascular filling defects (angiographic image analysis, n = 260, 2.81, 1.17-6.72, p<0.02) were strongly associated with death. Orange vessels had dense sequestration of late stage parasitised red cells (histopathology, n = 29; sensitivity 0.97, specificity 0.89) involving 360 degrees of the lumen circumference, with altered protein expression in blood retinal barrier cells and marked loss/disruption of pericytes. Retinal whitening was topographically associated with tissue response to hypoxia. Severe neurovascular sequestration is visible at the bedside, and is a marker of severe disease useful for diagnosis and management. PMID- 29578407 TI - Pauses in cholinergic interneuron firing exert an inhibitory control on striatal output in vivo. AB - The cholinergic interneurons (CINs) of the striatum are crucial for normal motor and behavioral functions of the basal ganglia. Striatal CINs exhibit tonic firing punctuated by distinct pauses. Pauses occur in response to motivationally significant events, but their function is unknown. Here we investigated the effects of pauses in CIN firing on spiny projection neurons (SPNs) - the output neurons of the striatum - using in vivo whole cell and juxtacellular recordings in mice. We found that optogenetically-induced pauses in CIN firing inhibited subthreshold membrane potential activity and decreased firing of SPNs. During pauses, SPN membrane potential fluctuations became more hyperpolarized and UP state durations became shorter. In addition, short-term plasticity of corticostriatal inputs was decreased during pauses. Our results indicate that, in vivo, the net effect of the pause in CIN firing on SPNs activity is inhibition and provide a novel mechanism for cholinergic control of striatal output. PMID- 29578408 TI - Differential 3' Processing of Specific Transcripts Expands Regulatory and Protein Diversity Across Neuronal Cell Types. AB - Alternative polyadenylation (APA) regulates mRNA translation, stability, and protein localization. However, it is unclear to what extent APA regulates these processes uniquely in specific cell types. Using a new technique, cTag-PAPERCLIP, we discovered significant differences in APA between the principal types of mouse cerebellar neurons, the Purkinje and granule cells, as well as between proliferating and differentiated granule cells. Transcripts that differed in APA in these comparisons were enriched in key neuronal functions and many differed in coding sequence in addition to 3'UTR length. We characterize Memo1, a transcript that shifted from expressing a short 3'UTR isoform to a longer one during granule cell differentiation. We show that Memo1 regulates granule cell precursor proliferation and that its long 3'UTR isoform is targeted by miR-124, contributing to its downregulation during development. Our findings provide insight into roles for APA in specific cell types and establish a platform for further functional studies. PMID- 29578409 TI - Spontaneous dormancy protects Trypanosoma cruzi during extended drug exposure. AB - The ability of the Chagas disease agent Trypanosoma cruzi to resist extended in vivo exposure to highly effective trypanocidal compounds prompted us to explore the potential for dormancy and its contribution to failed drug treatments in this infection. We document the development of non-proliferating intracellular amastigotes in vivo and in vitro in the absence of drug treatment. Non proliferative amastigotes ultimately converted to trypomastigotes and established infections in new host cells. Most significantly, dormant amastigotes were uniquely resistant to extended drug treatment in vivo and in vitro and could re establish a flourishing infection after as many as 30 days of drug exposure. These results demonstrate a dormancy state in T. cruzi that accounts for the failure of highly cytotoxic compounds to completely resolve the infection. The ability of T. cruzi to establish dormancy throws into question current methods for identifying curative drugs but also suggests alternative therapeutic approaches. PMID- 29578410 TI - A conserved function for pericentromeric satellite DNA. AB - A universal and unquestioned characteristic of eukaryotic cells is that the genome is divided into multiple chromosomes and encapsulated in a single nucleus. However, the underlying mechanism to ensure such a configuration is unknown. Here, we provide evidence that pericentromeric satellite DNA, which is often regarded as junk, is a critical constituent of the chromosome, allowing the packaging of all chromosomes into a single nucleus. We show that the multi-AT hook satellite DNA-binding proteins, Drosophila melanogaster D1 and mouse HMGA1, play an evolutionarily conserved role in bundling pericentromeric satellite DNA from heterologous chromosomes into 'chromocenters', a cytological association of pericentromeric heterochromatin. Defective chromocenter formation leads to micronuclei formation due to budding from the interphase nucleus, DNA damage and cell death. We propose that chromocenter and satellite DNA serve a fundamental role in encapsulating the full complement of the genome within a single nucleus, the universal characteristic of eukaryotic cells. PMID- 29578411 TI - Dendritic spikes in hippocampal granule cells are necessary for long-term potentiation at the perforant path synapse. AB - Long-term potentiation (LTP) of synaptic responses is essential for hippocampal memory function. Perforant-path (PP) synapses on hippocampal granule cells (GCs) contribute to the formation of associative memories, which are considered the cellular correlates of memory engrams. However, the mechanisms of LTP at these synapses are not well understood. Due to sparse firing activity and the voltage attenuation in their dendrites, it remains unclear how associative LTP at distal synapses occurs. Here, we show that NMDA receptor-dependent LTP can be induced at PP-GC synapses without backpropagating action potentials (bAPs) in acute rat brain slices. Dendritic recordings reveal substantial attenuation of bAPs as well as local dendritic Na+ spike generation during PP-GC input. Inhibition of dendritic Na+ spikes impairs LTP induction at PP-GC synapse. These data suggest that dendritic spikes may constitute a key cellular mechanism for memory formation in the dentate gyrus. PMID- 29578412 TI - Cytokine receptor-Eb1 interaction couples cell polarity and fate during asymmetric cell division. AB - Asymmetric stem cell division is a critical mechanism for balancing self-renewal and differentiation. Adult stem cells often orient their mitotic spindle to place one daughter inside the niche and the other outside of it to achieve asymmetric division. It remains unknown whether and how the niche may direct division orientation. Here we discover a novel and evolutionary conserved mechanism that couples cell polarity to cell fate. We show that the cytokine receptor homolog Dome, acting downstream of the niche-derived ligand Upd, directly binds to the microtubule-binding protein Eb1 to regulate spindle orientation in Drosophila male germline stem cells (GSCs). Dome's role in spindle orientation is entirely separable from its known function in self-renewal mediated by the JAK-STAT pathway. We propose that integration of two functions (cell polarity and fate) in a single receptor is a key mechanism to ensure an asymmetric outcome following cell division.

PMID- 29578414 TI - A mm-Sized Wireless Implantable Device for Electrical Stimulation of Peripheral Nerves. AB - A wireless electrical stimulation implant for peripheral nerves, achieving >10* improvement over state of the art in the depth/volume figure of merit, is presented. The fully integrated implant measures just 2 mm * 3 mm * 6.5 mm (39 mm3, 78 mg), and operates at a large depth of 10.5 cm in a tissue phantom. The implant is powered using ultrasound and includes a miniaturized piezoelectric receiver (piezo), an IC designed in 180 nm HV BCD process, an off-chip energy storage capacitor, and platinum stimulation electrodes. The package also includes an optional blue light-emitting diode for potential applications in optogenetic stimulation in the future. A system-level design strategy for complete operation of the implant during the charging transient of the storage capacitor, as well as a unique downlink command/data transfer protocol, is presented. The implant enables externally programmable current-controlled stimulation of peripheral nerves, with a wide range of stimulation parameters, both for electrical (22 to 5000 MUA amplitude, ~14 to 470 MUs pulse-width, 0 to 60 Hz repetition rate) and optical (up to 23 mW/mm2 optical intensity) stimulation. Additionally, the implant achieves 15 V compliance voltage for chronic applications. Full integration of the implant components, end-to-end in vitro system characterizations, and results for the electrical stimulation of a sciatic nerve, demonstrate the feasibility and efficacy of the proposed stimulator for peripheral nerves. PMID- 29578415 TI - [ENDOTHELIAL DYSFUNCTION AND MICROSCIRCULATION FEATURES IN PATIENTS WITH HIGH RISK OF DEVELOPMENT OF REPERFUSION SYNDROME IN CONDITIONS OF RECONSTRUCTION ARTERIAL OPERATIONS]. AB - Aim - to study the state of the microcirculatory bed and the endothelial system in patients at risk of developing reperfusion syndrome and suggest methods for their correction. The work included 29 patients with obliterating diseases of the abdominal aorta and lower limb arteries with a high risk of developing reperfusion complications. Two groups of patients were identified. Group I - 8 patients, preoperative preparation include the generally accepted approaches. Group II - 21 patients whose preoperative preparation included, in addition to preparations for improving rheological blood conditions, prolonged epidural anesthesia, intravenous injection of hydroxyethylstarches, korvetin and alprostadil. In patients of both groups, a study was made of the state of the level of endothelial dysfunction, changes in capillary blood flow and arterio venular blood shunting. Revascularization of the lower limbs in patients with a high risk of developing reperfusion complications leads to a deepening of endothelial dysfunction. The latter is characterized by a 2.3-fold increase (p<0.001) in the early postoperative period of circulating endothelial cells in the blood, by 2.5 times (p <0.001) endothelin-1, while a 1.3-fold decrease (p<0,05) P-selectin and in 1,7 times (p<0,05) E-selectin. The depth of the lesion of the endothelial system is indicated by a decrease of 29.9 % (p<0.001) in the level of NO. Deepening of endothelial dysfunction after reconstructive reconstructive surgery is reflected in violations of the function of the microcirculatory bed. It is characterized by a 1.9-fold decrease (p<0.001) of skin perfusion, 2.0 times (p<0.001) in the erythrocyte concentration index and a 14% decrease (p<0.05) in capillary blood flow. This is facilitated by an increase of 14% (p<0.05) in skin perfusion pressure and an increase of 16% (p<0.05) in the resistance index of the microcirculatory bed, which leads to a decrease in tissue oxygenation to a level 3.38+/-0.14 mm.hg.

AB - The purpose of the study was to determine appropriate diagnostic, therapeutic and rehabilitation treatments of patients with military-related craniocereberal trauma. We have examined 180 male patients: 100 participant of operations in the Democratic Republic Afghanistan (1979-1989) and 80 - participants of conflict in the east of Ukraine (from 2014 until present) with military-related craniocereberal trauma of varying severity. We used clinical-neurological, instrumental (craniography of skull, magnetic resonance imaging, ultrasonic doppler sonography of the main vessels of the head and neck), biochemical, statistical methods of a research, and also questionnaire scale SF-36. It was found that the quality of life of patients with military-related craniocereberal trauma depends on the severity of the wound and the period after trauma. In the early period after military-related craniocereberal trauma of light or average severity, the psychological components are more strongly manifested. Patients with severe military-related craniocereberal trauma have serious physical, psychological and social problems at different periods after trauma. The results of the research show that the quality of life depends on the severity of functional disorders and have impact on adaptive potential of the organism. PMID- 29578417 TI - RELATIONSHIP BETWEEN GENERAL HEALTH, ORAL HEALTH AND HEALTHY LIFESTYLE IN ELDERLY POPULATION (REVIEW). AB - This literature review aims to investigate how a poor oral health impacts on general health and healthy lifestyle of elderly people. The literature review was performed using ScienceDirect, Scopus and PubMed databases to identify relevant published studies. The year of publication was limited to over the past 5 years and the language was limited to English. Having considered the relevant articles' abstracts the 36 articles were selected. Systematical literature revision shows that recently, the older population has increased worldwide and it is being predicted to keep growing in near future. As age-related changes are observed in oral cavity, geriatric dentistry becomes more relevant to investigate oral disorders and to take relevant measures in elderly population. There is an urgent need to clarify the correlations between oral and general health. Unsatisfactory oral conditions lead to serious systemic diseases. Based on the currently available evidence, better collaboration between medical and dental fields is required in order to create and maintain healthy elderly population. A special association with professional group is important for implementation of new programs, in order to enhance and maintain satisfactory oral hygiene, oral health and oral health related quality of life. PMID- 29578418 TI - [TRANSOSSEOUS OSTEOSYNTHESIS OF LOWER EXTREMITIES BONES FRACTURES AND QUALITY OF LIFE OF PATIENTS IN THE TREATMENT PERIOD]. AB - The aim of the study is a comparative analysis of the quality of life in the treatment of fractures of the bones of the lower extremities of various localizations using transosseous and submerged osteosynthesis. We examined 397 patients with injuries of the lower segment of the lower extremity (patellar fractures - 81, multiple bones fractures of the tibia - 84 and fractures of the ankles, accompanied by a dislocation of the foot - 232). Patients were distributed in the subgroups depending on the treatment. The main group was performed using transosseous osteosynthesis, the comparison group - submerged osteosynthesis. The quality of life was examined using a general questionnaire SF 36 and specialized KOOS (with patella fractures) and FOAS (fractures of the bones of the lower leg and ankles). In patients with all localizations of fractures the quality of life was exceeded in the subgroups of the transosseous osteosynthesis group over the parameters of the comparison group. The most significant differences with the use of specialized questionnaires were revealed 6-9 months after trauma with a tendency to leveling to the end of the study (1 year). A more pronounced excess of the quality of life in the main group was seen in fractures of the shin bones. The study of the quality of life allows us to recommend the use of transosseous osteosynthesis for the treatment of lower segment of the lower limb bone fractures.

AB - The aim of the study was to determine the influence of oil products on the development of cervical pathology in women living in oil and gas bearing areas. A retro and prospective study of 300 women was conducted, of which 150 studied - Temir district (main group) and 150 women of Khobdinsky district (control group). It was revealed that a complex of unfavorable environmental factors affecting the body of women living in the oil and gas bearing area leads to deterioration of gynecological health and development of the precancerous process of the cervix: in women of the main group, under constant exposure to harmful factors, significantly more often than in women in the control group reveals precancerous conditions of the cervix of varying severity -28 (18.6%) and 9 (6%). Vaginal contents in women of the main group are characterized by significant disturbances in the microbial flora, which is manifested by a significant increase in the number of strict anaerobic bacteria, 69-46% and 31-20.6%, as compared with the control group. The increased generation of anaerobes is accompanied by a decrease in the frequency of lactobacilli, in particular lactobacilli, which in turn can lead to a disruption of the normal epithelization of the cervix.

AB - PCOS has a leading place in women's infertility. Based on the data of recent researches, Anti-Mullerian hormone (AMH) has been considered as one of the diagnostic criteria for PCOS. The aim of study was to determine the correlation of Anti-Mullerian hormone with hormonal and ovarian morphological characteristics in patients with PCOS, with and without insulin resistance. 110 women with diagnosis of PCOS were involved in the study. Patients were divided into two groups: PCOS patients with insulin resistance (60 women) and PCOS patients without insulin resistance (50 women). All patients underwent hormonal investigation (AMH, FSH, LH, T, FT, HOMA- IR, FAI and SHBG). The volume of ovaries and the number of antral follicles (AFC) were determined by ultrasound imaging. Sorrelation between AMH and the ovarian hormonal and morphological characteristics has been shown. In particular, a significant positive correlation between AMH and the volume of the ovaries in both groups was demonstrated. In the group of patients with PCOS and insulin resistance a positive correlation between AMH and the volum of ovary, AFC was shown, as well as a negative correlation between AMH and SHBG. In the same group a tendency of the positive correlation between AMH and TT, HOMA-IR and IRI was seen. In the group of patients with PCOS without insulin resistence a positive correlation between AMH and the volum of ovary was observed, as well as the tendency of positive correlation between AMH and AFC, TT, HOMA-IR, IRI. Additionally, a negative correlation between AMH and SHBG was seen in the later patient group. Increased levels of AMH in all PCOS patients in our study, in comparison with the accepted norm, indicates on possibility of using this data in the diagnosis of PCOS. AMH levels in PCOS patients with and without insulin resistance do not differ significantly. The correlation between AMH and the morphological characteristics of ovaries has been established. PMID- 29578421 TI - THE DIAGNOSTIC VALUE OF OSTEOPONTIN AS AN EARLY MARKER OF PILMONARY HYPERTENSION AFFECTED BY CHRONIC OBSTRUCTIVE PULMONARY DISEASE AND CONCOMITANT ISCHEMIC HEART DISEASE. AB - The article highlights the results of the study of the influence of osteopontin on the development of pulmonary hypertension in patients with COPD in combination with IHD. 121 patients with established diagnosis of COPD and IHD were randomized for the study, all patients underwent general clinical examination, spirography, ECG to determine the level of pulmonary artery pressure, a questionnaire according to the Borg and mMRC scales, and a 6-minute walk test. All patients were divided into 2 groups: group 1 (63 people) with the increased PA pressure, group 2 - comparison group - without PH (58 people). The conducted study suggests that the concentration of circulating osteopontin above 38.25 ng/ml can be considered as an early marker and an independent predictor of pulmonary hypertension in patients with COPD and concomitant IHD. In the PH (main) group osteopontin statistically significantly positively correlated with the age of patients, the right atrial area and the plasma level of interleukin 2 (IL-2). Interleukin 4 (IL-4), which is a marker of anti-inflammatory plasma activity, does not correlate with either pulmonary hypertension or osteopontin level, which indicates insufficient.

AB - The aim of the study was to study the effect of carbohydrate metabolism disturbances and other factors on the level of new biomarkers of P-selectin and Galectin-3 inflammation in patients with stable angina. The study included 119 patients with angina with or without diabetes mellitus, as well as patients with type 2 diabetes. Patients included in the study were tested in addition to standard methods to determine the levels of new biomarkers of inflammation of P selectin, Galectin-3 and hs-CRP. The data obtained showed that the levels of P selectin and Galectin-3 in patients with stable angina are interrelated, but vary significantly at the individual level, with both biomarkers of inflammation not associated with hs-CRP, which creates the prerequisites for the personalization of therapeutic goals in reducing the systemic inflammatory response. A higher level of P-selectin in a subgroup of patients with stable angina with concomitant diabetes mellitus was revealed in comparison with the subgroup of patients with DM without angina (119.9+/-30.1 and 79.3+/-38.2 ng/ml, p<0.05, respectively). P selectin is linked at the level of glycosylated hemoglobin (correlation coefficient = 0.256, p=0.043) and disorders of carbohydrate metabolism. However, the presence of myocardial ischemia influences the activation of the platelet component of inflammation to a greater extent. Galectin-3 was also linked according to the correlation analysis with violations of carbohydrate metabolism. The levels of P-selectin and Galectin-3 in the plasma of patients with angina pectoris were influenced by sex, age of patients and age at which angina was first diagnosed. However, the greatest effect on P-selectin and Galectin-3 levels was exerted by the degree of coronary atherosclerosis and the severity of angina pectoris according to loading test data. PMID- 29578423 TI - IMPACT OF RADIOFREQUENCY CATHETER ABLATION ON HEALTH-RELATED QUALITY OF LIFE ASSESSED BY THE SF-36 QUESTIONNAIRE IN PATIENTS WITH PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA. AB - The aim of the study was to investigate the effect of catheter ablation on different aspects of health-related quality of life in association with patients' age, gender and the type of paroxysmal supraventricular tachycardia. We investigated 70 consecutive patients with paroxysmal supraventricular tachycardia (AV Nodal Reentrant Tachycardia (AVNRT), AV Reentrant Tachycardia (AVRT) or Atrial Tachycardia (AT)) who underwent a catheter ablation. The patients were asked to fill out the short form (SF-36) health questionnaire before the ablation on the day of the procedure and after 3 months of a successful catheter ablation and eight health concept scores (1. Physical functioning; 2. Role limitations due to physical health; 3. Role limitations due to emotional problems; 4. Energy/fatigue; 5. Emotional wellbeing; 6. Social functioning; 7. Bodily pain; and 8. General health) were assessed before and after ablation. All health concept scores improved significantly after successful catheter ablation procedure. The result for the whole group were as follows: 1. physical functioning improved from mean 61.42+/-24.82 to 77.15+/-18.80 (p<0.001). 2. Score for the role limitations due to physical health improved from 41.78+/-39.17 to 75.35+/-33.91 (p<0.001). 3. Score for the role limitations due to emotional problems improved from 48.07+/-42.32 to 80.46+/-33.81 (p<0.001). 4. Energy/Fatigue score improved from 56.71+/-19.97 to 68.78+/-16.40 (p<0.001). 5. Emotional wellbeing score improved from 58.22+/-17.31 to 71.88+/-14.33 (p<0.001). 6. Social functioning score improved from 68.39+/-24.51 to 81.00+/-19.12 (p<0.001). 7. Pain score improved from 59.82+/-28.65 to 80.57+/-20.58 (p<0.001) and 8. General health score improved from 48.42+/-15.26 to 62.57+/-15.43 (p<0.001). This study shows that catheter ablation which can effectively cure the patients from the paroxysmal supraventricular tachycardia significantly improves physical, emotional and social health scores by eliminating the arrhythmia episodes and associated symptoms and anxiety in patients with paroxysmal supraventricular tachycardia irrespective of patient demographics and the type of the SVT. PMID- 29578424 TI - INFLUENCE OF CATHETER ABLATION OF PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA ON PATIENTS' ANXIETY. AB - The aim of the study was to investigate the influence of catheter ablation of paroxysmal supraventricular tachycardia on patients' anxiety levels. We investigated 70 consecutive patients with paroxysmal supraventricular tachycardia (AV Nodal Reentrant Tachycardia (AVNRT), AV Reentrant Tachycardia (AVRT) or Atrial Tachycardia (AT)) who underwent a catheter ablation. The patients filled out the State and Trait Anxiety Inventory (STAI) before the ablation on the day of the procedure and after 3 months of a successful catheter ablation. State and trait anxiety scores were compared before and after 3 months of ablation. The results were analyzed between different age (<50 vs >=50 y), gender and the type of paroxysmal supraventricular tachycardia (AVNRT vs AVRT/AT). Both state and trait anxiety scores improved significantly after catheter ablation. State anxiety score improved from mean 42.21+/-9.53 to 31.43+/-8.02 (p<0.001). Trait anxiety score improved from mean 45.76+/-7.80 to 39.80+/-7.33 (p<0.001). Present study demonstrates that the radiofrequency catheter ablation of paroxysmal supraventricular tachycardia by providing cure and eliminating the arrhythmia episodes significantly reduces both situational and general anxiety levels. PMID- 29578425 TI - NEW APPROACHES IN THE DIAGNOSTIC OF ICHTHYOSIS DISORDERS. AB - The aim of this study was to study the macroscopic changes in the skin of patients with various forms of ichthyosis to improve and optimize treatment. A comprehensive examination of 12 patients with ichthyosis under the supervision of a dermatovenereologist was conducted at VOKSHVD. For the diagnosis of macroscopic skin changes, the dermatoscopy was performed by the HEINE DELTA 20 (r) (Germany) apparatus, the results were recorded with a Canon 550D camera (Japan) at 1:35 or 1:30, with a sensitivity of IZO 200 using an adapter included with the dermatoscope. All affected skin were examined, which were compared with unharmed ones. The task was performed using the algorithm developed by us for dermatoscopic assessment of the severity of ichthyosis. The presence of typical dermatoscopic signs in examined patients with ichthyosis, which is manifested by the smoothness of the skin pattern, the presence of a pseudo-pigmental mesh, formed by keratin of scales in the form of lines, mesh and loop structures resembling cerebriform components, are established. The algorithm of estimation of expressiveness of dermatoscopic features for patients with light and severe clinical course of ichthyosis is proposed. Also, specific dermatological signs were observed in the mild clinical course of ichthyosis, in particular the phenomenon of "sparkling champagne", and in severe clinical course, the "melting ice" phenomal. The use of the dermatoscopic method makes it possible to objectively evaluate the severity of the ichthyosis and apply a differentiated approach to choosing the most effective treatment schemes. PMID- 29578426 TI - DYSFUNCTION OF VARIOUS ORGAN SYSTEMS INDUCED BY SEPSIS WITH UNDERLYING SEVERE MYELOMIC DISEASES AND PROSTATE CANCER (CASE REPORT). AB - A 65-year-old male patient, unconscious, was admitted into the clinic by the Ambulance. From the patient's medical history it was revealed that several hours before the admission in the clinic the following symptoms were present: shortness of breath, fever, hypotonia, consciousness inhibition, because of which emergency brigade was called and was brought by the Emergency Brigade. The history is loaded by chronic pathologies: myeloma disease, prostate cancer, ciliary arrhythmia, heart failure; received several courses of polichemotherapy, last ten days has been treated for pneumonia with antibiotics of ceftriaxone group in outpatient setting. It is also noteworthy that for the last three months dysfunction of musculoskeletal system with muscle weakness, restricted motion has been present. Clinically there was present dysfunction syndrome of several organs: disorder of function of several organs that required emergency intervention, recovery chance was very low, correlation with morbidity in PIRO was high. By investigation it is known, that as SIRS aggravates, and turns into septic shock, lethal index increases, especially when the underlying severe diseases are present. On basis of certain data we can conclude that the severity of the disease may have some compatibility with results, although it is alteration of further clinical status of initial stage that has the closest compatibility with results. Sepsis toward MODS experiences progress with lethal results. Mortality rate in the patients with acute respiratory deficiency increases from 50% to 80%. In most patients with sepsis syndrome, who have 3 or more organs damaged, lethality is more than 90%. In this certain case organ systems that are mostly involved in the process during the sepsis, are respiratory, blood, renal and cardiovascular systems, were all involved , in the mentioned case a reasonable symptomatic and pathognomic treatment and the appropriate measures led to the recovery of the above mentioned patient. Sepsis syndrome is developed when the balance between the substances that contribute to the inflammation and anti-inflammatory substances is violated. By the mentioned case there is sepsis - induced polyorganic insufficiency with underlying severe somatic pathological condition, with violation of hemodynamics. Clinically the insufficiency of all the organic systems developed at the background of cardio respiratory-cerebral insufficiency, with functional insufficiency of all the organ systems and violation of buffer system. With reasonable pathognomic and symptomatic treatment eradication of vicious circle was possible. The patient was discharged from the clinic with positive clinic-laboratory recovery.

AB - The data on occurrence and pathogenetic mechanisms of glucosylceramide lipidosis (Gaucher disease), which is based on the hereditary deficiency of glucocerebrosidase activity -the enzyme involved in the processing of cellular metabolism products, is presented. Clinical and morphological manifestations of the disease, therapeutic tactics and prognosis are defined. A typical clinical case of Gaucher disease type 1 in two adult patients was analyzed. It is shown that timely diagnosis of Gaucher disease allows the prescription of adequate treatment by means of enzyme replacement therapy with cerezyme drug. That is why the correct and timely diagnosis of the disease can prolongate patient's life for many years. In this case, the patient should be under the care of doctors (pediatricians, general physicians, hematologists). Continued treatment of Gaucher disease with cerezyme stabilizes the pathological process completely, decreases significant changes in bones and parenchymal organs, improving patients' lives considerably. For that reason, the sooner the adequate therapy is started, the more effective the results will be.

AB - Unilateral frontalis muscle palsy is a debilitating disease with a heterogeneous etiology. Congenital or acquired unilateral paralysis of the frontalis muscle causes ipsilateral brow ptosis and contralateral hypermobility of the non paralytic frontalis muscle, resulting in a bizarre asymmetry and emotional embarrassment. We present five patients with unilateral frontal muscle paralysis, two males and three females, aged between 32 and 68, treated with botulinum toxin A injection to the contralateral (non-affected) side. A total dose between 10 to 30 U botulinum toxin A (onabotulinum or incobotulinum toxin A) successfully improve symmetry and facial esthetics without any adverse events. Botulinum toxin A is an alternative to facial palsy surgery but may also be used as an adjunct after the surgical procedure to optimize the outcome.

AB - Keratoakanthoma (KA) is a common non-melanoma skin tumor of sun-exposed skin. Recently it has been classified as a highly differentiated squamous cell carcinoma, based on the evidence of local destruction, tissue invasion and malignant transformation with metastatic spread described in the medical literature. Lower lip KA is not uncommon on lower lip, and quite rare on upper lip. The authors present a case of 78-year-old Caucasian male patient with a rapidly growing keratotic tumor of the central region of upper lip. After complete surgical excision, single-stage reconstruction of the defect was performed by modified Goldstein's bilateral advancement myocutaneous vermilion flap. The histologic examination confirmed KA with excision margins within healthy tissue. Healing was unremarkable and functional and esthetic outcomes were very good. KA of the upper lip is a rare tumor that warrants complete surgical excision. Reconstruction of the central part of the upper lip is a challenge, but bilateral advancement myocutaneous vermilion flap resulted in good outcome.

The importance of timely diagnosis and treatment of such conditions is discussed. PMID- 29578431 TI - [CASE REPORT OF CANDIDA PNEUMONIA]. AB - Fungal pneumonia is considered as one of the most serious forms of pneumonia, the number of which has recently increased despite the use of new antimycotic drugs in pulmonology. Specificity of pathogens and torpid current of pneumomycosis represent great difficulties for accurate diagnosis and delay the timely onset of therapy, exacerbating inflammatory changes. In this article we present a rare case of isolated infection of the lungs parenchyma with Candida albicans in the form of focal pneumonia of the right lung lower lobe complicated by a clotted pleurisy. Patient is eighteen-year-old young man who is currently finding in the army. Our attention was attracted the fact that he was hospitalized twice within the 4 months with the same diagnosis - fungal pneumonia. At the same time, the localization of the process was the same as in the previous hospitalization. In this article, we tried to understand the reasons of unsuccessful treatment of this pathology. And we came to the following conclusions that the reason of repeated hospitalization of this patient was the short stay in the hospital and the duration of the diagnostic tests. Bacteriological examination of sputum takes about 5-7 days on average, which led to untimely started treatment. A short period of hospitalization, regulated by the protocols of diagnosis and treatment, contributed to inadequate treatment of this pathology. Thus, today there is a definite demand for the development of rapid diagnostic tests of fungal pneumonia and new protocols for diagnosis and treatment, taking into account the duration of treatment for Candida infection.

AB - Recently, the role of vasoactive peptides has been increasingly discussed in the pathogenesis of rosacea. The most attention is paid to the growth factor of the vascular endothelium (VEGF). VEGF affects angiogenesis and survival of immature blood vessels. Cytokine contributes to an increase in the level of IL-8, which plays a role in the development of inflammation. VEGF is synthesized by activated keratinocytes as a result of various factors. In particular, after exposure to ultraviolet irradiation, the production of cytokines-IL-1 and TNF-alpha-is provoced, which stimulate keratinocytes to synthesize of VEGF. The latest data on the state of the coagulation system in rosacea patients indicate a shift in the functional activity of the hemostasis system toward hypercoagulability. The aim of the study was to study the relationship between changes in the concentration of certain vasoactive peptides and the parameters of the hemostasis system in patients with rosacea. The state of the hemostasis system was assessed by prothrombin and thrombin time. The content of fibrinogen, fibrinolytic activity of blood, and also prothrombin index were determined as well. The concentration of free VEGF, IL-8 in the serum was determined by the method of enzyme immunoassay In the study, patients with rosacea, according to their age, were divided into 2 groups: -I group - patients aged 35 to 45 years, II group - patients aged 45 to 65 years. As the results of the study showed, the concentration of vasoactive peptides in patients with various clinical forms of rosacea differs significantly from those in the control group. In patients with various clinical forms of rosacea, the tendency of changes in all parameters (thrombin time, prothrombin time, fibrinogen, prothrombinic index) of the state of the coagulating system of blood with the manifestation of hypercoagulability is traced. And if the change in the content of cytokines was observed equally often in all observed patients, the manifestations of hypercoagulability were most pronounced in the second group of patients (aged 45 to 65 years) Thus, the results of the study allow us to conclude that an increase in the concentration of cytokines (which are a potent provoker of changes in permeability, atony and brittleness of the vessel walls), as well as hypercoagulable phenomena, indicative of ongoing microcracking processes, are the leading links in the pathogenesis of early forms of rosacea. PMID- 29578434 TI - POST-TRAUMATIC STRESS DISORDER AND COMORBIDITY: THE ROLE OF MEDIATION AND RELATION BETWEEN PTSD AND SOMATIC COMPLAINTS IN MENTAL HEALTH MANAGEMENT. AB - Several studies have demonstrated the relationship between PTSD, somatic symptoms, and the role of co-morbid depression and anxiety. A study was conducted to test whether symptoms of PTSD influence somatic complaints indirectly through underlying symptoms of depression and anxiety. The participants included 69 veterans following a 6-month deployment and who showed criteria for probable PTSD diagnosis. Data were collected in 2014 and 2015. Measures included the PTSD checklist (PCL-5) and subscales of the Patient Health Questionnaire (PHQ), including anxiety disorder, depression, and somatic complaints. Depressive symptoms, as well as anxiety symptoms, had significantly mediated the relationship between PTSD and somatic complaints and positively related to somatic symptom severity. Otherwise, depression is a more robust factor than anxiety. Both severities of anxiety and severity of depression were more strongly associated with somatic complaints than PTSD itself. These new findings may have implications for the management of PTSD treatment in Military mental health services as well as in public health management since it recognizes the importance of Comorbid depression and anxiety when somatic complaints are present.

AB - Despite the progress in the treatment of HF, its prognosis remains disappointing primarily due to the fact that important subgroups of patients with HF are not sufficiently investigated. This also applies to patients with HF and background metabolic disorders, in particular, type 2 diabetes. It is known that the polymorphism of the rs699 marker of the M235T ATG gene is associated with a tendency to arterial hypertension, coronary heart disease and atrial fibrillation. A relationship was found between the polymorphism of M235T and the risk of HF development. One of the promising new biomarkers is the fibrosis marker ST2. The purpose of our study was to evaluate the role of the biomarker ST2 and the genetic polymorphism of the AT2 gene M235T in the progression of CHF and the development of adverse events in patients with concomitant type 2 diabetes. We found that patients with HFpEF and T2DM with ATG TT + MT genotype have a higher level of ST2 and a higher probability of unfavorable cardiovascular events during 24 months of observation compared with MM genotype carriers.

AB - Study is devoted for rs1801270 polymorphism of CDKN1A gene due to the level of intensity of caries development in children with Down syndrome. The full development of oral cavity organs is ensured through a complex of genes whose protein products control different stages of this difficult process. Changes in gene structure, as well as disturbance of their expression may lead to abnormalities of development of teeth and periodontal tissues. Analysis of the polymorphism of CDKN1A gene Ser31Arg in children living in Kharkiv region has shown that the frequency of genotypes and alleles corresponds to the theoretically expected distribution by Hardy-Weinberg in the core (chi2=0.12) and control (chi2=1.29) groups. There is no significant differences in the frequency of alleles of CDKN1A gene in the group of healthy children and children with Down syndrome (p=0.978). There is an association of heterozygous option C/A of the studied marker Ser31Arg of CDKN1A gene with the level of intensity of caries development (by Leus) in children with Down syndrome under 10 years old.

AB - Numerous scientific studies demonstrating differences in pain sensitivity over various phases of the ovarian-menstrual cycle (OMC) in healthy women have been published in recent decades, but the basis for these differences is however still poorly understood. The aim of the current study was to assess the correlation between the heat pain threshold degree and the dynamics of TRPV1 (Transient receptor potential channeling subfamily V member1) receptor protein level, as well as aggression degree in healthy women in the follicular and luteal phases of OMC. An increased TRPV1 receptor protein level and a decreased thermal pain threshold were found in the luteal phase of the OMC. The study revealed a correlation of the progesterone level in the luteal phase with a degree of increase of TRPV1 level, as well as with the degree of decrease of heat pain threshold. The relationship between the degree of pain threshold, as well as TRPV1 level with follicle stimulating (FSH), luteinizing (LH) hormones and prolactin levels was not found. Also, there was no correlation between TRPV1 or heat pain threshold levels and aggression degree. PMID- 29578438 TI - THE MORPHOLOGICAL PICTURE OF LOCAL IMMUNE RESPONSES IN THE KIDNEYS, URETERS AND BLADDER OF THE FOETUSES AND NEWBORNS, WHO DEVELOPED IN CONDITIONS OF MATERNAL PREECLAMPSIA. AB - The purpose of the research consisted in revealing morphological peculiarities of local immune responses in the kidneys, ureters and bladder of the foetuses and newborns, who developed in conditions of maternal preeclampsia with different degrees of its severity. The research was conducted on autopsy material: the kidneys, ureters and bladders of mature foetuses and newborns. Four groups were formed in the study: group I - foetuses and newborns from mothers with physiological pregnancy; group II - foetuses and newborns from mothers, whose pregnancy was complicated with a mild degree of preeclampsia; group III - foetuses and newborns from mothers, whose pregnancy was complicated with a moderately severe degree of preeclampsia; group IV - foetuses and newborns from mothers, whose pregnancy was complicated with severe preeclampsia. An immune infiltration in the organs of the urinary system of foetuses and newborns was studied with help of histological, immunohistochemical and morphometric methods of examination. In the course of the study it was revealed that local immune responses in the kidneys, ureters and bladder of the foetuses and newborns passed with some abnormal deviations characterized by quantitative changes of SD3, SD4, SD8, SD20 and SD68 cells, whose degree of manifestation increased from the foetus to the newborn and with an aggravation of maternal preeclampsia. Mild, moderately severe as well as severe preeclampsia resulted in an extreme activation of the macrophage system, T cell and B cell immunity in the kidneys, ureters and bladder of foetuses and newborns that manifested itself with an increase of the absolute count of CD3, CD20 and CD68 cells. Mild preeclampsia caused an increase of the absolute count of CD8 cells and a decrease of the absolute count of CD4 cells with a resultant lowering of the immunoregulatory index. Moderately severe and severe preeclampsia caused an increase of the absolute count of CD4 cells and a decrease of the absolute count of CD8 cells with a corresponding elevation of the immunoregulatory index. In foetuses and newborns from mothers with physiological pregnancy as well as from mothers, whose pregnancy was complicated with preeclampsia having different degrees of severity, their kidneys were characterized by a more marked infiltration with immune cells versus their ureters and bladder. Thus, as a result of an excessive antigenic stimulation caused by maternal preeclampsia the local immune responses in the organs of the urinary system, which in physiological conditions fulfill exclusively protective functions, can become alterative and develop morphofunctional changes in the kidneys, ureters and bladder of foetuses and newborns. PMID- 29578439 TI - OCCUPATIONAL HAZARDS AS A RISK FACTOR OF ONSET AND UNFAVORABLE OUTCOME OF ISCHEMIC HEART DISEASE. AB - Objective -to identify the role of occupational hazards (OH) as a risk factor of onset and unfavorable outcome of coronary artery disease (CAD). Retrospective study included analysis of 307 case reports of CAD patients, including 59 patients with long term history of OH exposure. Prospective study included observation of 244 STEMI patients during their in-patient treatment, including 113 patients with prior exposure to OH. OH were demonstrated to contribute to the risk of CAD, and to be directly involved in atherosclerotic coronary artery (CA) injury, its role being equal to that of the classical risk factors, such as arterial hypertension (AH), dyslipidemia, and diabetes mellitus (DM). As shown by regression analysis, AH, DM, and dyslipidemia primarily promote atherogenesis in second and third order CA, while technogenic xenobiotics - mostly in first and second order CA, including the left CA truncus. History of OH directly affects the degree of stenosis, along with such important factors as LDL cholesterol, HDL cholesterol, triglycerides, and AH. According to Caplan-Meyer curves, OH exposure affects the hospital course of STEMI due to the adverse impact of technogenic xenobiotics leading, which contributes to the main mechanisms of CAD progression. In these patients the activity of systemic inflammation is higher, endothelial dysfunction, and autonomic disbalance and heterogeneity of myocardial repolarization are more profound. More pronounced remodeling of left ventricle, which is apparently due to the pre-existing abnormalities of cardiomyocytes caused by the long term effect of technogenic xenobiotics, significantly impairs the functional condition of myocardium, and accordingly the patient's prognosis. Our data suggest occupational hazards as a risk factor for onset and progression of CAD. Further studies involving this patient category are necessary.

AB - The objective of this researsh is to study the effects of Eminium Regelii phytopreparation (ERP) on immune status and free radical oxidation in the tissues of the adrenal glands and immunocompetent organs after combined exposure to 6 Gy dose of gamma irradiation and coal dust (remote period). The study was realized on 30 white laboratory male rats of the Wistar line, weighing 240+/-20g, that were divided into equal 3 groups: I group - intact, II group - were exposured to combined effects of coal dust and gamma irradiation, III group - were exposured to combined effects and in parallel taking phytopreparation Eminium Regel. The animals of II and III groups were irradiated 90 days prior to the study at the TERAGAM 60Co radiotherapy unit ("ISOTREND spol. S.r.o.", Czech Republic) in dose of 6 Gy once. Experimental animals received phytopreparation of ER 2.5 mg/kg per day on calculate of body mass for 14 days. The results of the conducted studies showed that in the long-term period after the actions of the sublethal dose of gamma radiation and coal dust, significant changes were revealed that were characterized by a decrease in immunological reactivity, increased lipoperoxidation and inhibition of antioxidant defense activity of the organism. After exposure to ER, oxidative stress was alleviated, sufficient restoration of antioxidant protection and immune system indices, which were disrupted by the combined effects of a single high dose of radiation and a prolonged three-month inhalation of coal dust. PMID- 29578441 TI - EFFECT OF TOBACCO SMOKE ON ROS PRODUCTION AND INFLAMMATION IN RATS OF DIFFERENT AGE. AB - The aim of our study was to investigate the effect of tobacco smoke on the content of reactive oxygen species (ROS) and level of cytokines in blood of rats of different age groups. For the purpose of carrying out the dosage, the beards of the white mongrel male rats were sub-divided into three groups: immature, mature and senile rats. Rat experimental groups were exposed to tobacco smoke daily for 45 days. The model of dependence on the chronic action of tobacco smoke was created using a sealed chamber in volume of 30 liters, which allowed to immerse animals in free behavior. Blood and blood serum was used for research. The isolation of neutrophils and lymphocytes from the blood was carried out by the method of gradient centrifugation on the double gradient of density ficol verografin. The ROS production level was analyzed according to the intensity of the fluorescence. The immune enzyme method, using test systems in the blood serum, determined the level of proinflammatory cytokine, interleukin 6 (IL-6) and anti-inflammatory - interleukin 4 (IL-4). It was found that exposure to tobacco smoke in rats developed oxidative stress, as evidenced by increased formation of ROS in neutrophils and blood lymphocytes of all the study groups of animals. In this case, the level of ROS depends not only on the age of the animals, but also on the duration of the action of tobacco smoke. In the blood serum of all age groups of rats, pronounced changes in IL-6 content were observed on the 45th day of exposure to tobacco smoke. The highest IL-6 content was observed in immature rats at the end of the experiment. . At the same time, the content of anti inflammatory cytokine IL-4 was significantly decreased in all age groups of animals. The results indicate an imbalance between the level of pro- and anti inflammatory cytokines, in particular IL-6 and IL-4. The result of exposure to tobacco smoke is the development of oxidative stress and inflammatory processes that depend on the duration of the smoke, its concentration, the age of the animals, and other biologically active constituents.

AB - In the world today, the demand for the preparations and cosmetics, made of peloids is increasing significantly, which is explained by the increased interest of the community to the ecologically clean raw materials of natural origin, it often replaces expensive chemical preparations, which are often accompanied by some contraindications. The increased interest in peloids in the world put on the agenda the question of rational use of acting mud mines as well as the problem of cosmetic and medicinal preparations, developed on their basis. It is noteworthy that the development of ready-made, soft drug forms from the Adjara region sulfide silt peloids is one of the most topical and important issues, as at present there is not available the form of ready-made drugs containing the sulfide silt peloids of this region. Therefore, the aim of the research was to develop the formulation and technology of the hydrogel, containing the Adjara region sulfide silt peloid. The sulfide silt peloid of the Ardagani lake have been used for preparing the hydrogel compositions, as it is distinguished by its advantageous physical-chemical properties and content of biologically active ingredients compared with other studied peloids. The main physical-chemical and technological characteristics of hydrogels compositions have been studied using the following methods: uniformity, pH, the colloidal stability, thermal stability , osmotic activity - by dialysis method using semiconductor membrane (Kruvichinski method), release of active ingredient was studied by using Franz diffusion cells, viscosity was determined by Viscometer RVDV-1 T (Dongguan Zhongli Instrument Technology Co., China), the structure of hydrogel composition by microscopic (ROW Rathenow, Germany) examination. Based on the conducted studies have been established, that the hydrogel composition N6 is distinguished by its best properties compared to other hydrogel compositions, in which the carboxymethylcellulose was used as a base.The conducted studies became the basis for the development of the formula and technological scheme of production for the hydrogel of Ardagani lake sulfide silt peloid of Adjara region. The results of determining the main characteristics of the given gel provide the desired quality and efficiency of the product.

AB - Rapid technology growth and its implementation in all spheres of the people's lives dictates the necessity for thorough study of the influence of different chemicals on human's health. This study was undertaken to elucidate the structural changes that occur in the matured rats' spleen experimentally induced by selected xenobiotic, so, purpose of our work was detection of microscopic peculiarities of the spleen under the influence of laproxides. In subacute experiment were uncovered organometric alterations of the matured male rat's spleen after the administration of 1/10 LD50 of polyether-tryglycidyl ether of polyoxypropylene triol (TEPPT). The study was performed on 72 outbreed WAG male matured rats with the weight 200+/-10g. Histological slides were studied with performing morphometric and statistical methods. We revealed changes of morphologis data in comparison to control data which shows reactivity of the spleen in response to the induced xenobiotic. The received and analyzed data demonstrate the morphological changes of the spleen, specifically changes of the linear dimensions and weight of the spleen due to the influence of the TEPPT. The spleen is very sensitive to the effects of xenobiotics, in particular, TEPPT that is even reflected in its grossly (weight and linear dimensions) and histological features (reliable changes of the of the white pulp area of the spleen from 17.87+/-1.04% to 27.37+/-1.71%, diameter of lymphatic follicles from 426.59+/ 11.18 MUm to 382.31+/-11.73 MUm, width of the mantle zone from 45.73+/-1.08 MUm to 37.18+/-2.29 MUm, width of the marginal zone from 81.32+/-1.79 MUm to 74.63+/ 2.08 MUm, width of the periarterial zone from 88.73+/-2.69 MUm to 97.24+/-2.61 MUm).

The purpose of this research is to study the particularity of angiogenesis and microcirculation in colon adenocarcinomas. The human tissue samples of colon adenocarcinoma (19 cases, 40 observation sites) were studied by light microscopic, electron- microscopic, electron-radiographic and immunohistochemical methods. For electron-radiographic studies - the sections of tissue were incubated separately in radioactive precursor 3H - thymidine and 3H - uridine. For immohistochemical studies markers CD34 and VEGF-A were used. According to analyzed data, de novo hyperplasia of endotheliocytes was detected by positive reaction on VEGF-A and CD34 markers in adenocarcinoma vascular structures. Special interest provide the VEGF-A and CD34 expression in stromal components. There is also an increase DNA synthesis in adenocarcinoma. Intra-tumor neoangiogenesis and changes in microcirculation are one of the most important factors regulating the processes of proliferation of atypical cells. The data obtained makes it possible to judge the prognosis, metastasis, and also the biopotential of neoplastic progression. PMID- 29578445 TI - EPIDEMIOLOGY OF CLOSTRIDIUM DIFFICILE INFECTION IN HOSPITALISED PEDIATRIC PATIENTS IN GEORGIA. AB - Clostridium difficile, a Gram-positive spore-forming bacillus, is the most common identifiable etiologic agent of antibiotic-associated diarrhea. The incidence of Clostridium difficile infections among hospitalized children has been increasing across the world. The aim of our study was to evaluate occurrence of Clostridium difficile and some other gastrointestinal pathogens among hospitalized pediatric patients in Georgia, as far as currently statistical data on the topic is very limited in the country. One of the objectives of the study was to test and pilot the real-time Polymerase Chain Reaction diagnostic systems for rapid and simultaneous identification of number of pathogens with a particular emphasis on diarrheal disease diagnostics as these are one of the primary public health priorities in Georgia and worldwide. Cross-Sectional study has been performed on 211 samples collected from 192 pediatric patients. Two pediatric hospitals were involved in the study: M. Iashvili Children's Central Hospital and Tbilisi Children's Clinical Hospital for Infectious Diseases. Laboratory investigations were done in the Clinic NeoLab, Tbilisi, Georgia. Study materials collected for testing were stool samples. Samples were tested by EIA kits (CerTest biotec, Zaragoza, Spain) for presence of A/B toxin according to the manufacturer's instructions. EIA test positive samples were analyzed by home-made multiplex real time polymerase chain reaction (NeoPCR Diagnostics, NeoLab, Tbilisi, Gerogia) for confirmation of the infection and for simultaneous identification of additional gastrointestinal pathogens including Entamoeba histolitica, Giardia lamblia, Cryptsporidium parvum, Adenovirus, Rotavirus, Norovirus and Astrovirus. All samples were also tested for the presence of the above listed pathogenic agents using the same type EIA kits as for Clostridium difficile described above (CerTestbiotec, Zaragoza, Spain) for presence of the corresponding pathogen. The average age of the study participants was 3.5 years, 56.7% were male and 43.3% were female patients. Presence of Clostridium difficile have been documented in 21 samples out of 211 (10%). Besides the Clostridium difficile, other enteric pathogens have been revealed with the following frequencies: Rotavirus in 12 cases (5.7%), Adenovirus in 11 (5.2%), Giardia lamblia in 10 (4.7%), Astrovirus in 3 (1.4%), Cryptsporidium parvum in 3 (1.4%), Entamoeba histolitica in 2 (0.9%), Norovirus in 2 (0.9%). 49 samples were from out-patient cases (2 samples were positive for Clostridium difficile) and 162 samples were from in-patient cases (19 samples were positive for Clostridium difficile). Clostridium difficile is the frequent pathogenic agent causing diarrheal disease among hospitalized pediatric patients. Development of Clostridium difficile related diarrhea is associated with the antibiotic treatment of pediatric patients hospitalized due to different clinical diagnosis. Targeted early detection of these pathogens is important for the optimal management of diarrheal infection in pediatric patient which will lead to the better clinical outcome and reduction of morbidity rate among hospitalized pediatric patients. PMID- 29578446 TI - SELF-PERCEIVED HEALTH STATUS AND ILLNESSES AMONG INTERNALLY DISPLACED PEOPLE IN GEORGIA. AB - Georgia had several waves of internally displaced people (IDPs) as a result of military conflicts on the territories of Abkhazia and Samachablo starting from 1990's with the latest large wave in 2008. Most of the IDPs live in compact settlements, such as old administrative buildings or specially constructed camps. In both cases, living conditions and social-economic status of IDPs are below Georgia's national average. There is extremely limited data on the health status of the IDPs in Georgia. Health Research Union (HRU) with support from ELRHA/R2HC program conducted a survey to study health service utilization and expenditures among IDPs, and measure the effect of targeted intervention versus untargeted, integrated approach to health financing. The aim of the current study was to analyze the self-reported health status among IDPs on the basis of the data collected through this survey. The survey was carried out among IDPs currently living in Georgia mainly residing in compact settlements. Sampling from the target population was performed by a multi-stage cluster sampling approach. In total 1.319 households with 4,359 household members were recruited and interviewed for the survey. Male accounted for almost 55% of all household members in the survey. Slightly less than half of respondents were married; children under the age of 15 constituted 23% of all IDPs surveyed. In total, 40% of all respondents (1729 persons) report being chronically ill and identify a wide range of conditions. Of them 532 report having 2 or more chronic diseases. About a third of occurrences (29%) of chronic diseases is attributed to cardiovascular diseases. Musculoskeletal and gastrointestinal diseases (each) constitute 13% of all occurrences of chronic diseases. During last 24 months 129 household members gave birth. The prevalence of chronic diseases among adult population increases as the age advances with the highest rate among those aged above 65 with 84% reporting having at least one chronic disease. Self-perceived overall health status was characterized as excellent, very good and good by 53%, as fair by 32% and as poor and very poor by 16% of the respondents. The conducted research was the first wide-scale study of the health status among internally displaced people in Georgia. These data may contribute to better understand the problems in this vulnerable population and evaluate impact of the implementation of the different models of the health care including targeted health insurance for IDPs.

AB - The capsids of certain Archaea-infecting viruses undergo large shape changes, while maintaining their integrity against rupture by osmotic pressure. We propose that these capsids are in a smectic liquid crystalline state, with the capsid proteins assembling along spirals. We show that smectic capsids are intrinsically stabilized against the formation of localized bulges with non-zero Gauss curvature while still allowing for large-scale cooperative shape transformation that involves global changes in the Gauss curvature. PMID- 29578448 TI - Laser bioprinting of human induced pluripotent stem cells-the effect of printing and biomaterials on cell survival, pluripotency, and differentiation. AB - Research on human induced pluripotent stem cells (hiPSCs) is one of the fastest growing fields in biomedicine. Generated from patient's own somatic cells, hiPSCs can be differentiated towards all functional cell types and returned to the patient without immunological concerns. 3D printing of hiPSCs could enable the generation of functional organs for replacement therapies or realization of organ on-chip systems for individualized medicine. Printing of living cells was demonstrated with immortalized cell lines, primary cells, and adult stem cells with different printing technologies and biomaterials. However, hiPSCs are more sensitive to handling procedures, in particular, when dissociated into single cells. Both pluripotency and directed differentiation are influenced by numerous environmental factors including culture media, biomaterials, and cell density. Notably, existing literature on the effect of applied biomaterials on pluripotency is rather ambiguous. In this study, laser bioprinting of undifferentiated hiPSCs in combination with different biomaterials was performed and the impact on cells' behavior, pluripotency, and differentiation was investigated. Our findings suggest that hiPSCs are indeed more sensitive to the applied biomaterials, but not to laser printing itself. With appropriate biomaterials, such as the hyaluronic acid based solutions applied in this study, hiPSCs can be successfully laser printed without losing their pluripotency.

AB - Photoactive perovskite quantum dot films, deposited via an inkjet printer, have been characterized by x-ray diffraction and x-ray photoelectron spectroscopy. The crystal structure and bonding environment are consistent with CsPbBr3 perovskite quantum dots. The current-voltage (I-V) and capacitance-voltage (C-V) transport measurements indicate that the photo-carrier drift lifetime can exceed 1 ms for some printed perovskite films. This far exceeds the dark drift carrier lifetime, which is below 50 ns. The printed films show a photocarrier density 109 greater than the dark carrier density, making these printed films ideal candidates for application in photodetectors. The successful printing of photoactive-perovskite quantum dot films of CsPbBr3, indicates that the rapid prototyping of various perovskite inks and multilayers is realizable.

AB - Multiphoton interaction of coherent electromagnetic radiation with 2D metallic carriers confined on the surface of the 3D topological insulator is considered. A microscopic theory describing the nonlinear interaction of a strong wave and metallic carriers with many-body Coulomb interaction is developed. The set of integrodifferential equations for the interband polarization and carrier occupation distribution is solved numerically. Multiphoton excitation of Fermi Dirac sea of 2D massless carriers is considered for a THz pump wave. It is shown that in the moderately strong pump wave field along with multiphoton interband/intraband transitions the intense radiation of high harmonics takes place.

AB - We revise a phase diagram for the sliding Luttinger liquid (SLL) of coupled one dimensional quantum wires packed in two- or three-dimensional arrays in the absence of a magnetic field. We analyse whether physically justifiable (reasonable) inter-wire interactions, i.e. either the screened Coulomb or 'Coulomb-blockade' type interactions, stabilise the SLL phase. Calculating the scaling dimensions of the most relevant perturbations (the inter-wire single particle hybridisation, charge-density wave, and superconducting inter-wire couplings), we find that their combination always destroys the SLL phase for the repulsive intra-wire interaction. However, suppressing the inter-wire tunnelling of repulsive fermions (when the charge-density wave is the only remaining perturbation), one can observe a stability region emerging due to the inter-wire forward scattering interaction.

AB - OBJECTIVE: Previous studies showed success using wrist-worn accelerometers to monitor upper-limb activity in adults and children with hemiparesis. However, a knowledge gap exists regarding which specific joint movements are reflected in accelerometry readings. We conducted a case series intended to enrich data interpretation by characterizing the influence of different pediatric upper-limb movements on accelerometry data. APPROACH: The study recruited six typically developing children and five children with hemiparetic cerebral palsy. The participants performed unilateral and bilateral activities, and their upper limb movements were measured with wrist-worn accelerometers and the Microsoft Kinect, a markerless motion-capture system that tracks skeletal data. The Kinect data were used to quantify specific upper limb movements through joint angle calculations (trunk, shoulder, elbow and wrist). Correlation coefficients (r) were calculated to quantify the influence of individual joint movements on accelerometry data. Regression analyses were performed to examine multi-joint patterns and explain variability across different activities and participants. MAIN RESULTS: Single-joint correlation results suggest that pediatric wrist-worn accelerometry data are not biased to particular individual joint movements. Rather, the accelerometry data could best be explained by the movements of the joints with the most functional relevance to the performed activity. SIGNIFICANCE: This case series provides deeper insight into the interpretation of wrist-worn accelerometry data, and supports the use of this tool in quantifying functional upper-limb movements in pediatric populations.

AB - Despite the knowledge that the influenza protein, hemagglutinin, undergoes a large conformational change at low pH during the process of fusion with the host cell, its molecular mechanism remains elusive. The present constant pH molecular dynamics (CpHMD) study identifies the residues responsible for large conformational change in acidic condition. Based on the pKa calculations, it is predicted that His-106 is much more responsible for the large conformational change than any other residues in the hinge region of hemagglutinin protein. Potential of mean force profile from well-tempered meta-dynamics (WT-MtD) simulation is also generated along the folding pathway by considering radius of gyration (R gyr) as a collective variable (CV). It is very clear from the present WT-MtD study, that the initial bending starts at that hinge region, which may trigger other conformational changes. Both the protein-protein and protein-water HB time correlation functions are monitored along the folding pathway. The protein-protein (full or hinge region) HB time correlation functions are always found to be stronger than those of the protein-water time correlation functions. The dynamical balance between protein-protein and protein-water HB interactions favors the stabilization of the folded state.

AB - We study quantum entanglement loss due to environmental interaction in a condensed matter system with a complex geometry relevant to recent proposals for computing with single electrons at the nanoscale. We consider a system consisting of two qubits, each realized by an electron in a double quantum dot, which are initially in an entangled Bell state. The qubits are widely separated and each interacts with its own environment. The environment for each is modeled by surrounding double quantum dots placed at random positions with random orientations. We calculate the unitary evolution of the joint system and environment. The global state remains pure throughout. We examine the time dependence of the expectation value of the bipartite Clauser-Horne-Shimony-Holt (CHSH) and Brukner-Paunkovic-Rudolph-Vedral (BPRV) Bell operators and explore the emergence of correlations consistent with local realism. Though the details of this transition depend on the specific environmental geometry, we show how the results can be mapped on to a universal behavior with appropriate scaling. We determine the relevant disentanglement times based on realistic physical parameters for molecular double-dots. PMID- 29578455 TI - Spin Hall effect originated from fractal surface. AB - The spin Hall effect (SHE) has shown promising impact in the field of spintronics and magnonics from fundamental and practical points of view. This effect originates from several mechanisms of spin scatterers based on spin-orbit coupling (SOC) and also can be manipulated through the surface roughness. Here, the effect of correlated surface roughness on the SHE in metallic thin films with small SOC is investigated theoretically. Toward this, the self-affine fractal surface in the framework of the Born approximation is exploited. The surface roughness is described by the k-correlation model and is characterized by the roughness exponent H [Formula: see text], the in-plane correlation length xi and the rms roughness amplitude delta. It is found that the spin Hall angle in metallic thin film increases by two orders of magnitude when H decreases from H = 1 to H = 0. In addition, the source of SHE for surface roughness with Gaussian profile distribution function is found to be mainly the side jump scattering while that with a non-Gaussian profile suggests both of the side jump and skew scatterings are present. Our achievements address how details of the surface roughness profile can adjust the SHE in non-heavy metals.

AB - SrAl2O4-Sr3Al2O6 eutectic glass was prepared by using an aerodynamic levitator equipped with a CO2 laser device. A bulk transparent amorphous sample was obtained by the spark plasma sintering (SPS) of the prepared eutectic glass. XRD, a UV-vis-NIR spectrophotometer and FT-IR were employed to characterize the phase evolution and optical properties. The results show that the bulk SrAl2O4-Sr3Al2O6 samples fabricated by the containerless process and SPS between 852 degrees C 857 degrees C were fully amorphous. The amorphous sample has a wide transparent window between 270 nm and 6.2 MUm. The average refractive index in the visible light region is 1.680 and the Abbe number is 27.4. The prepared bulk SrAl2O4 Sr3Al2O6 eutectic glass with the wide-band optical window may be a promising candidate for optical applications.

AB - Black phosphorus, a two-dimensional material, with high carrier mobility, tunable direct bandgap and anisotropic electronic properties has attracted enormous research interest towards potential application in electronic, optoelectronic and optomechanical devices. The bandgap of BP is thickness dependent, ranging from 0.3 eV for bulk to 1.3 eV for monolayer, while lacking in the visible region, a widely used optical regime for practical optoelectronic applications. In this work, photoluminescence (PL) centered at 605 nm is observed from the thermally annealed BP with thickness <=20 nm. This higher energy PL is most likely the consequence of the formation of higher bandgap phosphorene oxides and suboxides on the surface BP layers as a result of the enhanced rate of oxidation. Moreover, the polarization-resolved PL measurements show that the emitted light is anisotropic when the excitation polarization is along the armchair direction. However, if excited along zigzag direction, the PL is nearly isotropic. Our findings suggest that the thermal annealing of BP can be used as a convenient route to fill the visible gap of the BP-based optoelectronic and optomechanical devices. PMID- 29578459 TI - The relationship between serum E2 levels and recurrence in premenopausal, ER positive breast cancer patients: A retrospective study. AB - BACKGROUND: Among estrogens, estradiol (E2) has the strongest physiological activity as a stimulator in estrogen receptor (ER)-positive breast cancer. The aim of this study is to investigate E2 dynamics during endocrine therapy and to explore the optimal environment in which tamoxifen (TAM) exhibits better efficacy for ER-positive premenopausal early breast cancer patients. METHODS: This is a retrospective study enrolled 194 patients with premenopausal ER-positive early stage breast cancer who aging <=45 years at onset and receiving luteinizing hormone-releasing hormone-agonist (LHRH-a) and TAM-therapy. Approximately half of the patients also received pre- or post-operative chemotherapy as adjuvant systemic therapy. We studied the relationship between recurrence and serum hormonal dynamics during adjuvant therapy. We monitored the concentrations of E2 and, follicle-stimulating hormone (FSH) in the blood before, during, and after treatment. The median follow-up period was 80 (14-555) months. RESULTS: Forty-six (23.7%) patients developed recurrent breast cancer after surgery. The prognoses were favorable in the group receiving longer LHRH-a exposure if those patients did not receive chemotherapy as their adjuvant therapy. Paradoxically, patients with high serum E2 levels after LHRH-a showed a low recurrence ratio. This phenomenon might be explained by the similar mechanisms of estrogen therapy after estrogen depletion by aromatase inhibitor (AI) therapy for metastatic breast cancer. CONCLUSION: Among patients who received endocrine therapy without adjuvant chemotherapy, those with longer LHRH-a exposure had favorable prognoses. A potential association was observed between recurrence and E2 concentrations in women with premenopausal ER-positive early-stage breast cancer. PMID- 29578460 TI - Recovery time course of erythrocyte deformability following exposure to shear is dependent upon conditioning shear stress. AB - BACKGROUND: Red blood cell (RBC) deformability may increase, or decrease, following application of shear stress ("shear conditioning"), depending upon the specific magnitude and duration of exposure. However, the time course of altered RBC deformability following shear remains unresolved. OBJECTIVE: We utilised shear conditioning known to increase (10 Pa) or decrease (64 Pa) RBC deformability and subsequently rested the cells; serial measurements of deformability during the rest period facilitated defining the time course of recoverability. A second experiment repeated the shear conditioning and recovery period to explore whether multiple duty-cycles augmented the response following the initial exposure. METHODS: Shear conditioning was performed for 300 s at the desired shear stress. Ektacytometry was used to quantify human RBC deformability immediately and during rest (3, 5, 60, 120, 240, 300 s) using discrete samples. RBC were shear conditioned twice in a separate experiment, with 300 s rest separating the conditioning. RESULTS: Shear conditioning at 10 Pa induced increased cell deformability by 19.5 +/- 0.3%, which reduced to 7.2 +/- 0.4% after 300 s of rest. Shear conditioning at 64 Pa decreased cell deformability by 30.5 +/- 13.9%, and after 300 s rest, remained decreased (19.3 +/- 9.4%) compared with baseline. The second duty-cycle augmented initial responses induced by shear conditioning. CONCLUSION: Specific shear conditioning results in either temporarily increased cell deformability, or a less reversible decrease of RBC deformability.

AB - BACKGROUND: Isometric cervical flexor system exercise (ICF) and isometric cervical extensor system exercise (ICE) are cervical stabilization techniques that have been used to restore cervical crossed syndrome (CCS)-associated forward head posture. However, the therapeutic effects and underlying motor control mechanisms remain elusive. PURPOSE: The purpose of present study was investigating the concurrent therapeutic effects of ICF and ICE on muscle size, muscle imbalance ratio, and muscle recruitment sequence using ultrasound imaging and electromyography. METHODS: A total of 18 participants (7 females; age=24+/ 4.0 years) with CCS associated with forward head posture underwent ICF and ICE. Paired t-test analysis was used for statistical analysis. RESULTS: Paired t-test analysis showed that sternocleidomastoid thickness was greater during ICF than ICE. Similarly, cross-sectional area and horizontal thickness of the longus colli were greater during ICE than ICF. The upper trapezius/lower trapezius muscle imbalance ratio and the pectoralis major/lower trapezius muscle imbalance ratio were significantly decreased during the application of ICE compared to ICF. CONCLUSIONS: These results provide compelling, mechanistic evidence as to how ICE is more beneficial for the restoration of neuromuscular imbalance than ICF in individuals with CCS.

AB - Nanosuspensions technique is an important tool to enhance the saturation solubility and dissolution velocity of poorly soluble drugs. Trans-resveratrol (t Res) with extensive pharmacological effects was severely restricted by poor solubility and short biological half-life. In this study, anti-solvent precipitation was employed to development trans-resveratrol nanosuspensions (t Res NS) with PVPK30 as stabilizer. The physicochemical properties, in vitro release and in vivo pharmacokinetics of t-Res NS were investigated. The mean particle size, zeta potential, encapsulation efficiency and drug loading of t-Res NS prepared by the optimal prescription were 96.9 nm, -20.4mV, 78% and 28.1%, respectively. The morphology of t-Res nanoparticles was spherical indicated by SEM with amorphous phase verified by XRD and DSC. The t-Res NS present a good physical stability as well as enhanced chemical stability. Compared to crude drug, the in vitro dissolution rate of t-Res NS was increased with fitting Higuchi equation (Q=0.3215t1/2+0.0070). The in vivo pharmacokinetic test in rats showed that the AUC0~t of t-Res NS (559.4 MUg/mL.min) was about 3.6-fold higher than that of t-Res solution. Meanwhile, the MRT of t-Res nanosuspensions was longer than that of t-Res solution. These results suggested that NS may be a potentially nanocarrier for clinical delivery of t-Res.

AB - BACKGROUND: Novel pectin-honey hydrogels have been developed and characterized as medical device. Ideally, a wound dressing should maintain optimal fluid affinity, permit moisture evaporation, protect the wound from microbes, and have shape conformability, biocompatibility, and antibacterial activity. OBJECTIVE: A novel, simple and fast method to produce pectin-honey wound dressings is described. METHODS: The properties of these pectin-honey hydrogels were investigated, including swelling ability, water vapour transmission rate, hydrogen peroxide production, methylglyoxal content and antibacterial activity. Biocompatibility was assessed by proliferation assays using cultured fibroblast cells and by in vivo study with subcutaneous and intraperitoneal implantation in rats. RESULTS: Hydrogel showed a good water vapour transmission rate, fluid uptake and were not cytotoxic for fibroblasts. The hydrogel demonstrated good antibacterial activity toward clinically relevant pathogens, including S. aureus and E. coli. Biocompatibility was confirmed by the measurement of plasma levels of interleukin (IL)1 beta, IL-6, tumour necrosis factor (TNF) alpha, and prostaglandin (PG)E2. No histological changes were observed. CONCLUSIONS: The presence of a natural active component, conformability, and complete resorbability are the main characteristics of this new biocompatible biomaterial that is well tolerated by the body, possibly improves healing, may be used for surgical complications prevention, with a simple and inexpensive production process. PMID- 29578464 TI - Biological and nano-indentation properties of polybenzoxazine-based composites reinforced with zirconia particles as a novel biomaterial. AB - INTRODUCTION: The biological and mechanical properties of substances are relevant to their application as biomaterials and there are many efforts to enhance biocompatibility and mechanical properties of bio-medical materials. OBJECTIVES: In this study, to achieve a low rate of shrinkage during polymerization, good mechanical properties, and excellent biocompatibility, benzoxazine based composites were synthesized. METHODS: Benzoxazine monomer was synthesized using a solventless method. FTIR and DSC analysis were carried out to determine the appropriate polymerization temperature. The low viscosity of the benzoxazine monomer at 70 degrees C attract us to use in situ polymerization after high speed ball milling of the benzoxazine and it mixture with different weight fractions of zirconia particles. Dispersion and adhesion between the ceramic and polymer components were evaluate by SEM. To evaluate the biological properties and toxicity of the polybenzoxazine-based composite samples reinforced with zirconia particles, 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay was conducted. The micromechanical properties of each composite were evaluated by more than 20 nanoindentation tests and 3 nanoscratching tests. Surface topography of scratched regions was investigated using Atomic Force Microscopy. Shrinkage was simulated by Materials Studio software. RESULTS: SEM images showed good dispersion and adhesion between the ceramic and polymer components. Biocompatibility assay showed excellent in vitro biocompatibility. Nano indentation force-displacement curves showed matrix, reinforcement and interphase regions in specimens and excellent homogeneity in mechanical properties. The nanoindentation results showed that the addition of zirconia particles to the polybenzoxazine matrix increased the modulus and hardness of the neat polybenzoxazine; however, by adding more than an optimum level of reinforcement particles, the mechanical properties decreased due to the agglomeration of reinforcement particles and weak interphase that cause inappropriate load transferring between matrix and reinforcement particles. Results of nano scratching tests showed effects of zirconia particles as reinforcement on the coeffiecient of friction of the synthesized composites. Shrinkage simulation showed a low rate of shrinkage for polybenzoxazine in comparison with other low shrinkage polymers, such as Bis-GMA. CONCLUSION: Polybenzoxazine based composites that reinforced with an optimum amount of zirconia particles (60% wt micro and 10% wt nano-particles) could be used as a novel biomaterial duo to its excellent biocompatibility, good mechanical properties, appropriate viscosity and low rate of polymeization shrinkage. PMID- 29578465 TI - Fluid-structure interaction of patient-specific Circle of Willis with aneurysm: Investigation of hemodynamic parameters. AB - BACKGROUND: Circle of Willis (COW) is a network of cerebral artery which continually supplies the brain with blood. Any disturbance in this supply will result in trauma or even death. One of these damages is known as brain Aneurysm. Clinical methods for diagnosing aneurysm can only measure blood velocity; while, in order to understand the causes of these occurrences it is necessary to have information about the amount of pressure and wall shear stress, which is possible through computational models. OBJECTIVE: In this study purpose is achieving exact information of hemodynamic blood flow in COW with an aneurysm and investigation of effective factors on growth and rupture of aneurysm. METHODS: Here, realistic three-dimensional models have been produced from angiography images. Considering fluid-structure interaction have been simulated by the ANSYS.CFX software. RESULTS: Hemodynamic Studying of the COW and intra-aneurysm showed that the WSS and wall tension in the neck of aneurysms for case A are 129.5 Pa, and 12.2 kPa and for case B they are 53.3 Pa and 56.2 kPa, and more than their fundus, thus neck of aneurysm is prone to rupture. CONCLUSION: This study showed that the distribution of parameters was dependent on the geometry of the COW, and maximum values are seen in areas prone to aneurysm formation. PMID- 29578467 TI - The influence of curvature wall on the blood flow in stenosed artery: A computational study. AB - The current study investigates the curvature effect due to various angles of curvature on the blood flow in human artery. The stenosis is considered to have three sizes 70%, 80% and 90% blockage before the curve section of artery. Numerical study of four different angle of curvature was considered to understand the flow behavior of artery having various curvatures, on the hemodynamics factors that includes drop in arterial pressure, flow velocity as well as wall shear stress. It was found that, the augmentation of the flow resistance due to the curvature increases in presence of stenosis. It was also noted that the wall shear is higher at the outer wall as compared to the inside wall in four models considered. Results showed that both the curvature of artery and size of the stenosis have significant impact. These two factors should be considered by cardiologist to assess the complexity of stenosis.

AB - BACKGROUND: The data on biomaterial-mediated bone regeneration directly comparing commercially available scaffolds in aging and osteoporotic conditions remain sparse. OBJECTIVE: To investigate the effects of an absorbable collagen sponge (ACS) and a medical grade polycaprolactone-tricalcium phosphate (mPCL-TCP) scaffold on calvarial defect healing in ovary-intact and ovariectomized rats. METHODS: Forty-two, 5-month old female Sprague-Dawley rats were divided into sham (OVI) or ovariectomy (OVX) groups (n=21). When rats reached 6 months old, 7 mm diameter calvarial defects were created and treated, further dividing each group into blood clot control, mPCL-TCP, or ACS subgroups (n=7). After four weeks, the calvarial specimens were evaluated using micro-computed tomography for bone volume fraction (BVF), and histopathology. RESULTS: The effects of ovariectomy were confirmed by changes in body, uterine, and vaginal weight, and osteopenia in the femur. A significant increase in BVF was observed in ACS-subgroups compared with their respective control groups (p<0.05). Histopathological analysis revealed no cellular inflammatory infiltrate in any group. Fibrous tissue encapsulated the mPCL-TCP, while the ACS was well-integrated with the bone matrix. The OVX groups presented more osteoid and enlarged marrow cavities compared with the OVI groups. CONCLUSION: ACS scaffold enhanced calvarial bone regeneration in OVI and OVX rats after four weeks.

AB - During the last two decades, biodegradable/absorbable materials which have many benefits over conventional implants are being sought in clinical practices. However, to date, it still remains obscure for us to perform full physic-chemical characterization and biological risk assessment for these materials and related devices due to their complex design and coherent processing. In this review, based on the art of knowledge for biodegradable/absorbable materials and biological risk assessment, we demonstrated some promising strategies to establish and improve the current biological evaluation systems for these biodegradable/absorbable materials and related medical devices. PMID- 29578469 TI - An alternative solvent for electrospinning of fibrinogen nanofibers. AB - Fibrinogen plays a necessary role in blood clotting and wound healing. In this study, a new solvent mixture of formic acid/acetic acid with low toxicity was investigated as an alternative solvent for fibrinogen electrospinning. The nanofibers were analyzed by scanning electron microscope (SEM), simultaneous thermal analysis (STA) and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). The results showed that when the ratio of formic acid to acetic acid was 75/25 (v/v) the finest defect-free fibres with diameters ranging from 184 +/- 37 to 241 +/- 70 nm were obtained. In addition, the average fibre diameters increase with increasing concentration of fibrinogen from 10wt% to 12wt%. It is concluded that solvent mixture consisting of formic acid/acetic acid can be a great solvent for electrospinning of fibrinogen and is able to produce nanofiber structures. PMID- 29578470 TI - Development of asymmetric stent for treatment of eccentric plaque. AB - The selection of stent and balloon type is decisive in the stenting process. In the treatment of an eccentric plaque obstruction, a symmetric expansion from stent dilatation generates nonuniform stress distribution, which may aggravate fibrous cap prone to rupture. This paper developed a new stent design to treat eccentric plaque using structural transient dynamic analysis in ANSYS. A non symmetric structural geometry of stent is generated to obtain reasonable stress distribution safe for the arterial layer surrounding the stent. To derive the novel structural geometry, a Sinusoidal stent type is modified by varying struts length and width, adding bridges, and varying curvature width of struts. An end ring of stent struts was also modified to eliminate dogboning phenomenon and to reduce the Ectropion angle. Two balloon types were used to deploy the stent, an ordinary cylindrical and offset balloon. Positive modification results were used to construct the final non-symmetric stent design, called an Asymmetric stent. Analyses of the deformation characteristics, changes in surface roughness and induced stresses within intact arterial layer were subsequently examined. Interaction between the stent and vessel wall was implemented by means of changes in surface roughness and stress distribution analyses. The Palmaz and the Sinusoidal stent were used for a comparative study. This study indicated that the Asymmetric stent types reduced the central radial recoiling and the dogboning phenomenon. In terms of changes in surface roughness and induced stresses, the Asymmetric stent has a comparable effect with that of the Sinusoidal stent. In addition, it could enhance the distribution of surface roughening as expanded by an offset balloon.

AB - OBJECTIVE: To help patients with disabilities of the arm and shoulder recover the accuracy and stability of movements, a novel and simple virtual rehabilitation and evaluation system called the Kine-VRES system was developed using Microsoft Kinect. METHODS: First, several movements and virtual tasks were designed to increase the coordination, control and speed of the arm movements. The movements of the patients were then captured using the Kinect sensor, and kinematics-based interaction and real-time feedback were integrated into the system to enhance the motivation and self-confidence of the patient. Finally, a quantitative evaluation method of upper limb movements was provided using the recorded kinematics during hand-to-hand movement. RESULTS: A preliminary study of this rehabilitation system indicates that the shoulder movements of two participants with ataxia became smoother after three weeks of training (one hour per day). CONCLUSION: This case study demonstrated the effectiveness of the designed system, which could be promising for the rehabilitation of patients with upper limb disorders. PMID- 29578472 TI - Bioinformatics analysis of novel transcription factors and related differentially regulated modules in non-union skeletal fractures. AB - OBJECTIVE: This study aimed to further clarify the underlying pathomechanism of non-union skeletal fractures. METHODS: Gene expression profile dataset GSE494 obtained from six non-union skeletal fracture and six normal samples was downloaded from the Gene Expression Omnibus database. Overlapping genes in at least two platforms were analyzed, and differentially expressed genes (DEGs) between normal and disease groups were screened. Transcriptional regulatory relationships and differentially regulated modules of various transcription factors (TFs) were determined. Differentially regulated modules with unknown functions were subjected to functional enrichment analysis. RESULTS: Overall, 4,252 overlapping genes in at least two platforms and 77 DEGs, including 31 up and 46 downregulated genes, were obtained. Overall, 64,623 transcriptional regulatory relationships, including 49 TFs and 3,900 target genes, and 9 significant modules for differential regulation were identified. Three modules with unknown functions regulated by TFs, including zinc finger, ZZ-type containing 3 (ZZZ3), nuclear TF Y, alpha (NFYA), and POU class 2 homeobox 2 (POU2F2), were identified. Enriched GO-BP terms of NFYA and POU2F2 modules included cell adhesion and related terms and those of ZZ3 included cell cycle, cell proliferation, and associated terms. CONCLUSION: Three TFs, including ZZZ3, POU2F2, and NFYA, and their regulated modules may have important effects on non union skeletal fractures. Cell proliferation may be related with ZZZ3; cell adhesion and its similar process may be related with POU2F2 and NFYA. PMID- 29578473 TI - Medial collateral ligament bursitis in a patient with knee osteoarthritis. AB - BACKGROUND: Medial collateral ligament (MCL) bursitis has been described as a distended and inflamed bursa between the superficial and deep portions of the MCL. It is a rare but important cause of medial knee pain. CASE DESCRIPTION: A 65 year-old woman with knee osteoarthritis (OA) presented with severe pain and swelling in her left knee. She did not have a traumatic injury. After a clinical examination, a slight decrease in the range of motion of the left knee, and a painful swelling and tenderness over the medial side of the knee and proximal tibia were detected. The pain was exacerbated by valgus stress test. The magnetic resonance (MR) imaging showed a distended bursa with internal septations beneath the superficial portion of the MCL. MCL bursitis was considered as diagnosis and an ultrasound-guided corticosteroid injection into the bursa was performed. RESULTS: There was a significant improvement in pain intensity in the follow-up examination. A repeated MR imaging 2 months later showed a marked improvement, and approximation of the deep and superficial portions of the MCL. CONCLUSIONS: MCL bursitis, which is a rare condition, must be considered for the differential diagnosis of increased medial knee pain in patients with knee OA. Corticosteroid injection is an effective and safe treatment modality for the management. PMID- 29578474 TI - Relationship of hematologic markers with IL-17 and IL-1 beta in patients with rheumatoid arthritis. AB - OBJECTIVES: In this study, we aimed to investigate the relationship of NLR (Neutrophil lymphocyte ratio), MPV (mean platelet volume), PDW (distribution width) rates in rheumatoid arthritis (RA) patients with IL-17 and IL-1 beta which are within the cytokines playing an important role in etiopathogenesis and activity of the disease. PATIENTS AND METHODS: Fifty-seven RA patients diagnosed according to RA classification criteria of ACR/EULAR 2010 and 37 controls were included into the study. WBC (white blood cell), NEU (neutrophil), PLT (platelet), LYM (lymphocyte) values in complete blood count received from routine blood examination of patients were recorded, and NLR, PLR (platelet lymphocyte ratio) rates were recorded. IL-17 and IL-1 beta were studies in serum samples. Disease activity of RA patients was evaluated with Disease Activity Score (DAS28). Age, gender, disease age, BMI (body mass index), medications used, co morbid diseases, smoking of the patients were recorded. RESULTS: Fifty-seven RA patients (46 (80.7%) females, 11 (19.3%) males), and 34 patients (24 (70.6% females and 10 (29.4) males) as a control group were involved. Demographic characteristics were similar between two groups, and statistically significant difference was not detected between patient and control groups in terms of gender, age, and BMI (p> 0.05). We found higher NLR, MPV, PDW, IL-17 values in RA patients compared to control group (p< 0.05). There was a positive correlation of NLR with DAS28, CRP. While erythrocyte sedimentation rate (ESR) had negative correlation with MPV and PDW, it had positive correlation with PLT. We found positive correlation of C-reactive protein (CRP) with NLR and PLT. We could not find correlation of IL-1 beta and IL-17 with hematologic markers. CONCLUSION: In this study, we investigated the relationship of IL-17 and IL-1 beta which play an important role in pathogenesis of RA patients with the parameters analyzed in routine complete blood count, providing information about disease activity such as DAS 28, CRP, and ESR. We illuminated on an issue which has not discussed before by looking from a different angle. More extensive, follow-up studies are needed to emphasize the importance of these parameters and to reveal the relationship between cytokines during the follow-up of the disease activity. PMID- 29578475 TI - Recovery from nonspecific neck pain in office workers. AB - BACKGROUND: Neck pain has an episodic course with varying time for recovery and identification of individuals likely to recover is important. OBJECTIVE: The aim of this study was twofold: 1a) to explore the duration of recovery from nonspecific neck pain, and 1b) to investigate the relation between recovery duration and age, and 2) to evaluate whether the NHBOW can predict duration of recovery from non-specific neck pain. METHODS: One hundred and three from 342 office workers reported non-specific neck pain, with information collected on pain intensity and disability every month for 12 months. The time to recovery was measured from the onset of neck pain to full recovery. The 103 office workers were divided into two groups using the NHBOW score. Kaplan-Meier survival curves were used to describe the median time to recovery. The survival curves of the two NHBOW groups were compared using Cox regression analysis. RESULTS: The median time to recovery from neck pain was 2 months. The duration of recovery was not significantly related with age of participants. There was no significant difference in time to recovery from neck pain between the NHBOW low-score group and the high-score group. CONCLUSION: This study showed that the NHBOW was unable to predict duration of recovery from nonspecific neck pain in office workers. PMID- 29578476 TI - Urinary incontinence due to lumbar spinal stenosis causing disability and lowering quality of life. AB - OBJECTIVES: Lumbar spinal stenosis may lead to urinary inconsistence and can have a negative impact on the quality of life. The aim of the study was to assess the incidence of urinary incontinence and quality of life in female patients with spinal canal stenosis comparing to control group. METHODS: The study population consisted of 50 women diagnosed with severe lumbar spinal canal stenosis. Their mean age was 55.32 +/- 12.97 years. The clinical control group consisted of 30 women who did not suffer from any spine disorders. Their mean age was 54.87 +/- 12.01 years. There was no difference between both groups regarding age, weight, BMI and number of parity. The women diagnosed with clinical and radiographic symptoms of spinal canal stenosis filled out an anonymous questionnaire, ODI, ICIQ-UI-SF, and ICIQ-LUTSqol questionnaires. RESULTS: We found urinary incontinence in 56% of women with lumbar spinal canal stenosis and in 43% of clinical control group. We also found a statistically significant correlation between duration of lumbar stenotic symptoms, the SLR sign, number of deliveries and the intensity of urinary incontinence. CONCLUSIONS: Urinary incontinence in women with lumbar spinal canal stenosis is significantly different from the control group. Leakage of urine happened more frequently, the amount of urine leaked was greater, and the general impact on everyday life is harsher, as compared to the clinical control group. PMID- 29578477 TI - Morpho-functional implications of myofascial stretching applied to muscle chains: A case study. AB - BACKGROUND: Most lesions of the soft tissues, especially those at the muscle level, are due to the lack of elasticity of the connective tissue and fascia. Stretching is one of the most commonly used methods of treatment for such musculoskeletal issues. OBJECTIVE: This study tracks the effects of stretching on the electromyographic activity of muscle chains, applied to a 24-year-old athlete diagnosed with the Haglund's disease. METHOD: For the evaluation, we used visual examination and surface electromyography (maximum volumetric isometric contraction). The therapeutic intervention consisted in the application of the static stretching positions, which intended the elongation of the shortened muscle chains. The treatment program had a duration of 2 months, with a frequency of 2 sessions per week and an average duration of 60 minutes. RESULTS: The posterior muscle chains recorded an increase in the EMG activity, while the anterior muscle chains tended to diminish their EMG activity. As a result of the applied treatment, all the evaluated muscle chains recorded a rebalancing of the electromyographic activity, demonstrating the efficiency of stretching as a method of global treatment of muscle chains. CONCLUSIONS: By analysing all the data, we have come to the conclusion that static stretching is an effective treatment method for shortened muscle chains. PMID- 29578478 TI - Screening of scoliosis in school children in Tehran: The prevalence rate of idiopathic scoliosis. AB - BACKGROUND: Scoliosis is the abnormal sideways curve of the spine. Screening for scoliosis is controversial, and there has been significant heterogeneity between studies. In Iran, there is still no suitable device to screen sideways curves in spine. OBJECTIVE: To investigate the simple scolioscreen software for screening the students of elementary schools for detecting schoolchildren scoliosis. This students has been examined by trained medical student and data entered in scolioscreen application of an iPhone. METHODS: One hundred forty-four 7-12 years old students from primary schools in the 17th district of Tehran were randomly invited to participate. Initial screening of the students was done in schools by health care provider or medical student who has been trained by a pediatrician to undergo a vertebral examination. Scoliometer for iPhone's smartphone has been used for measuring the angle of deviation. RESULTS: 1.4% of students had overt scoliosis and 10.4% were suspected to have a kind of mild abnormality in spine curve. These individuals were referred to clinic for radiologic evaluation and it was confirmed that relative frequency of this abnormality was defined as 4.86% in our population study. There was no significant correlation between sex and degree of spinal curve. CONCLUSIONS: Regarding the high rate of scoliosis in our population and approval of this screening test in different studies, routine use of this screening method is highly recommended in schoolchildren. It is cost beneficial and can be effective in prevention and early treatment of scoliosis. PMID- 29578479 TI - Comprehensive Characterization of the Pyroglutamate Amyloid-beta Induced Motor Neurodegenerative Phenotype of TBA2.1 Mice. AB - Alzheimer's disease (AD) is the most common neurodegenerative disorder and is being intensively investigated using a broad variety of animal models. Many of these models express mutant versions of human amyloid-beta protein precursor (AbetaPP) that are associated with amyloid-beta protein (Abeta)-induced early onset familial AD. Most of these models, however, do not develop bold neurodegenerative pathology and the respective phenotypes. Nevertheless, this may well be essential for their suitability to identify therapeutically active compounds that have the potential for a curative or at least disease-modifying therapy in humans. In this study, the new transgenic mouse model TBA2.1 was explored in detail to increase knowledge about the neurodegenerative process induced by the presence of pyroglutamate modified human Abeta3-42 (pEAbeta3-42). Analysis of the sensorimotor phenotype, motor coordination, Abeta pathology, neurodegeneration, and gliosis revealed formation and progression of severe pathology and phenotypes including massive neuronal loss in homozygous TBA2.1 mice within a few months. In contrast, the start of a slight phenotype was observed only after 21 months in heterozygous mice. These data highlight the role of pEAbeta3-42 in the disease development and progression of AD. Based on the findings of this study, homozygous TBA2.1 mice can be utilized to gain deeper understanding in the underlying mechanisms of pEAbeta3-42 and might be suitable as an animal model for treatment studies targeting toxic Abeta species, complementary to the well described transgenic AbetaPP mouse models. PMID- 29578481 TI - Deficits in Regional Cerebral Blood Flow on Brain SPECT Predict Treatment Resistant Depression. AB - BACKGROUND: Depression remains an important risk factor for Alzheimer's disease, yet few neuroimaging biomarkers are available to identify treatment response in depression. OBJECTIVE: To analyze and compare functional perfusion neuroimaging in persons with treatment resistant depression (TRD) compared to those experiencing full remission. METHODS: A total of 951 subjects from a community psychiatry cohort were scanned with perfusion single photon emission computed tomography (SPECT) of the brain in both resting and task related settings. Of these, 78% experienced either full remission (n = 506) or partial remission (n = 237) and 11% were minimally responsive (n = 103) or non-responsive (11%. n = 106). Severity of depression symptoms were used to define these groups with changes in the Beck Depression Inventory prior to and following treatment. Voxel based analyses of brain SPECT images from full remission compared to the worsening group was conducted with the statistical parametric mapping software, version 8 (SPM 8). Multiple comparisons were accounted for with a false discovery rate (p < 0.001). RESULTS: Persons with depression that worsened following treatment had reduced cerebral perfusion compared to full remission in the multiple regions including the bilateral frontal lobes, right hippocampus, left precuneus, and cerebellar vermis. Such differences were observed on both resting and concentration SPECT scans. CONCLUSION: Our findings identify imaging-based biomarkers in persons with depression related to treatment response. These findings have implications in understanding both depression to prognosis and its role as a risk factor for dementia. PMID- 29578480 TI - Preserved Structural Network Organization Mediates Pathology Spread in Alzheimer's Disease Spectrum Despite Loss of White Matter Tract Integrity. AB - Models of Alzheimer's disease (AD) hypothesize stereotyped progression via white matter (WM) fiber connections, most likely via trans-synaptic transmission of toxic proteins along neuronal pathways. An important question in the field is whether and how organization of fiber pathways is affected by disease. It remains unknown whether fibers act as conduits of degenerative pathologies, or if they also degenerate with the gray matter network. This work uses graph theoretic modeling in a longitudinal design to investigate the impact of WM network organization on AD pathology spread. We hypothesize if altered WM network organization mediates disease progression, then a previously published network diffusion model will yield higher prediction accuracy using subject-specific connectomes in place of a healthy template connectome. Neuroimaging data in 124 subjects from ADNI were assessed. Graph topology metrics show preserved network organization in patients compared to controls. Using a published diffusion model, we further probe the effect of network alterations on degeneration spread in AD. We show that choice of connectome does not significantly impact the model's predictive ability. These results suggest that, despite measurable changes in integrity of specific fiber tracts, WM network organization in AD is preserved. Further, there is no difference in the mediation of putative pathology spread between healthy and AD-impaired networks. This conclusion is somewhat at variance with previous results, which report global topological disturbances in AD. Our data indicates the combined effect of edge thresholding, binarization, and inclusion of subcortical regions to network graphs may be responsible for previously reported effects. PMID- 29578482 TI - Olfactory Function is Associated with Cognitive Performance: Results of the Heinz Nixdorf Recall Study. AB - BACKGROUND: There is strong evidence for an association of olfactory dysfunction and neurodegenerative diseases. Studies on the association of olfaction and cognition in the general population are rare. OBJECTIVE: To evaluate gender- and age-specific associations of olfactory function and cognitive performance in a well characterized population-based study sample. METHODS: At the third examination of the Heinz Nixdorf Recall study (n = 3,087), 2,640 participants (48% men; 68.2+/-7.2 years) underwent Sniffin' Sticks Screening Test measuring olfactory function on a scale of 0-12 points. Olfactory function was rated as anosmic, hyposmic, or normosmic (<=6, 7-10 or >=11 points, respectively). All participants performed eight validated cognitive subtests. Age- (55-64 years, 65 74 years, 75-86 years) and gender-stratified multivariate analysis of covariance was used to evaluate group differences in cognitive performance. RESULTS: Women showed better olfactory function than men (p < 0.001). For middle-aged participants, olfactory groups differed in almost all cognitive subtests. The analyses revealed no gender effects, although associations were slightly greater for women than for men. Anosmics showed the worst cognitive performance and normosmics showed the best cognitive performance. In the young- and old-aged groups, a quantitative association was found for anosmics in all subtests and for normosmics and hyposmics in almost all subtests. CONCLUSION: This is the first study reporting on age-specific associations of olfactory function and cognitive performance in the general population. The association found in middle-aged participants (65-74 years) may serve as a marker to improve identification of persons at high risk for cognitive decline and dementia. PMID- 29578483 TI - Polypharmacy and Potentially Inappropriate Medication in People with Dementia: A Nationwide Study. AB - BACKGROUND: Polypharmacy (use of >=5 different medications) and potentially inappropriate medication (PIM) are well-known risk factors for numerous negative health outcomes. However, the use of polypharmacy and PIM in people with dementia is not well-described. OBJECTIVE: To examine the prevalence of polypharmacy and PIM in older people with and without dementia in a nationwide population. METHODS: Cross-sectional study of the Danish population aged >=65 in 2014 (n = 1,032,120) based on register data, including information on diagnoses and dispensed prescriptions. Polypharmacy and PIM use among people with (n = 35,476) and without dementia (n = 994,231) were compared, stratified by living situation and adjusted for age, sex, and comorbidity. The red-yellow-green list from the Danish Institute for Rational Pharmacotherapy and the German PRISCUS list were used to define PIM. RESULTS: People with dementia were more frequently exposed to polypharmacy (dementia: 62.6% versus no-dementia: 35.1%, p < 0.001) and likewise PIM (red-yellow-green: 45.0% versus 29.7%, p < 0.001; PRISCUS: 24.4% versus 13.2%, p < 0.001). After adjustments for age, sex, and comorbidity, the likelihood of polypharmacy and PIM was higher for community-dwelling people with dementia than without dementia (odds ratio (OR); [95% confidence interval (CI)] polypharmacy: 1.50 [1.45-1.55]; red-yellow-green: 1.27 [1.23-1.31]; PRISCUS: 1.25 [1.20-1.30]). In contrast, dementia slightly decreased the odds of polypharmacy and PIM in nursing home residents. CONCLUSION: Use of polypharmacy and PIM were widespread in the older population and more so in people with dementia. This could have negative implications for patient-safety and demonstrates the need for interventions to improve drug therapy in people with dementia. PMID- 29578484 TI - HSV-1-Specific IgG Subclasses Distribution and Serum Neutralizing Activity in Alzheimer's Disease and in Mild Cognitive Impairment. AB - Human Herpes Simplex Virus type 1 (HSV-1) infection is suggested to play a role in the development of Alzheimer's disease (AD). Immunoglobulin G (IgG) neutralize HSV-1 activity, but the virus can evade IgG-mediated immune responses by expressing receptor that efficiently binds the Fc portion of all IgG subclasses with the exception of IgG3. We analyzed HSV-1-specific IgG subclasses and IgG mediated serum neutralization activity against HSV-1 in individuals with a diagnosis of either AD or mild cognitive impairment (MCI), comparing the results with those obtained in age-matched healthy controls (HC). 186 individuals were enrolled in the study: 67 AD, 58 MCI, and 61 HC. HSV-1 IgG titers and subclasses, neutralizing antibody (NAb) titers, and complement C3 concentration-critical component of antibody-mediated effector activity-were measured in sera by ELISA; IgG neutralizing activity was performed on HSV-1 infected Vero cells. Results showed that, whereas HSV-1-specific IgG1, IgG2, and IgG4 titers as well as complement C3 serum concentration were comparable in all groups of individuals, IgG3 were more frequently detected in MCI (89%) compared to AD (75%; p < 0.05) and HC (68%; p = 0.003), whereas the titer is similar among the three groups (AD: 0.66+/-0.21 OD; MCI: 0.68+/-0.24 OD; HC: 0.72+/-0.28 OD). Notably, HSV-1 specific neutralizing ability of AD sera was reduced even in the presence of high quantity of IgG3. As IgG3 plays a key role in counteracting the ability of HSV-1 to evade immune responses, these data reinforce the hypothesis of a pathogenetic role of HSV-1 in AD. PMID- 29578485 TI - Cysteine-Rich Repeat Domains 2 and 4 are Amyloid-beta Binding Domains of Neurotrophin Receptor p75NTR and Potential Targets to Block Amyloid-beta Neurotoxicity. AB - The p75 neurotrophin receptor (p75NTR) is an amyloid-beta (Abeta) receptor that both mediates Abeta neurotoxicity and regulates Abeta production and deposition, thus playing an important role in the pathogenesis of Alzheimer's disease (AD). The extracellular domain of p75NTR (p75ECD), consisting of four cysteine-rich repeat domains (CRDs), was recently reported to be an endogenous anti-Abeta scavenger to block p75NTR-mediated neuronal death and neurite degeneration signaling of Abeta and pro-neurotrophins. Identification of the specific Abeta binding domains of p75NTR is crucial for illuminating their interactions and the etiology of AD. CRDs of p75ECD were obtained by expression of recombinant plasmids or direct synthesis. Abeta aggregation inhibiting test and immunoprecipitation assay were applied to locate the specific binding domains of Abeta to p75ECD. The Abeta neurotoxicity antagonistic effects of different CRDs were examined by cytotoxicity experiments including neurite outgrowth assay, propidium iodide (PI) staining, and MTT assay. In the Abeta aggregation inhibiting test, the fluorescence intensity in the CRD2 and CRD4 treatment groups was significantly lower than that in the CRD1 and CRD3 treatment groups. Immunoprecipitation assay and western blot confirmed that Abeta could bind to CRD2 and CRD4. Besides, CRD2 and CRD4 antagonized Abeta neurotoxicity suggested by longer neurite length, less PI labelled cells, and higher cell viability than the control group. Our results indicate that CRD2 and CRD4 are Abeta binding domains of p75NTR and capable of antagonizing Abeta neurotoxicity, and therefore are potential therapeutic targets to block the interaction of Abeta and p75NTR in the pathogenesis of AD. PMID- 29578486 TI - Volume and Connectivity of the Ventral Tegmental Area are Linked to Neurocognitive Signatures of Alzheimer's Disease in Humans. AB - BACKGROUND: There is an urgent need to identify the earliest biological changes within the neuropathological cascade of Alzheimer's disease (AD) processes. Recent findings in a murine model of AD showed significant preclinical loss of dopaminergic neurons in the ventral tegmental area (VTA), accompanied by reduced hippocampal innervation and declining memory. It is unknown if these observations can be translated in humans. OBJECTIVE: We tested the hypothesis that VTA volume is associated with the typical clinical markers of AD in a cohort of patients and healthy controls. METHODS: Structural and resting state functional MRI scans, and neuropsychological scores were acquired for 51 healthy adults, 30 patients with a diagnosis of mild cognitive impairment, and 29 patients with a diagnosis of AD dementia. VTA volume was quantified together with other control nuclei. The association between nuclei volume, hippocampal size, memory performance, and linguistic-executive skills was tested. The effect of VTA functional connectivity was also tested. RESULTS: VTA size, but not of control nuclei, yielded a strong association with both hippocampal size and memory competence (but not linguistic executive performance), and this was particularly strong in healthy adults. In addition, functional connectivity between the VTA and hippocampus was significantly associated with both markers of AD. CONCLUSION: Diminished dopaminergic VTA activity may be crucial for the earliest pathological features of AD and might suggest new strategies for early treatment. Memory encoding processes may represent cognitive operations susceptible to VTA neurodegeneration. PMID- 29578487 TI - Call for a Uniform Strategy of Collecting Alzheimer's Disease Costs: A Review and Meta-Analysis. AB - BACKGROUND: There is now a general attempt in developed countries to implement strategic plans to fight against Alzheimer's disease and other dementia disorders. Among others, attention is paid to the issues of registers and calculations of economic burden. Currently available calculations of costs are difficult to compare. The problem is a different breakdown of cost categories and non-unified monitoring of cost types. OBJECTIVE: The aim of this paper is to note the problem of poor availability and inconsistencies in cost monitoring. Furthermore, the intersection of cost items that are comparable and consistently monitored in expert studies are specified. METHODS: The Web of Science, Elsevier Science Direct, PubMed, and Scopus databases are used in a systematic review. Two independent reviewers screened the identified records and selected relevant articles published in the period from 2010 to 2016. A meta-analysis of costs is performed in four categories related to patients suffering from Alzheimer's disease. RESULTS: The resulting estimation of total costs per patient per month through meta-analysis is ? 3,896, with 95% CI [2078, 5713]. The highest costs arise from informal care following non-medical and medical care. CONCLUSION: The results confirm assumption that inconsistencies in cost monitoring of the treatment and care of people with dementia exists in Europe. Homogeneity could be assumed only in the medical costs of severe patients. Heterogeneity is assumed in non-medical costs, informal costs. Cost items should be defined and collected more precisely for future more precise monitoring of the economic burden. PMID- 29578489 TI - REM Sleep Behavior Disorder and Alzheimer's Disease: Definitely No Relationship? AB - Rapid eye movement (REM) sleep behavior disorder (RBD) is a REM sleep parasomnia characterized by the loss of the typical muscular atonia present during healthy REM sleep. RBD can occur in the absence of other neurological conditions or in association with a neurodegenerative disorder. It is now well established that RBD is a strong predictor of neurodegeneration, in particular synucleinopathies, such as Parkinson's disease, Lewy body dementia (LBD), or multiple system atrophy. However, some longitudinal studies report that a minority of patients develop either overlapping form of dementia or Alzheimer disease's (AD). Although AD is reported as a possible development in patients with RBD, it is in a limited number of cases and there are concerns about the accuracy of the diagnostic criteria. Neuropsychological impairments identified in cross-sectional studies of RBD patients describe a profile similar to that observed in dementia related to synucleinopathies. However, only deficits in executive function predict the development of neurodegeneration. Longitudinal studies reported the development of AD in RBD patients in about 7% of cases with variability ranging from 3% and 11%. Since the majority of longitudinal investigations do not report AD as a possible development for RBD patients the proportion may be overestimated. The study of the relationship between RBD and AD may be confounded by two factors that lead to misdiagnosis: the use of clinical criteria alone and the overlap between the clinical features and neuropathology of AD and LBD. Future studies to investigate this association must use updated diagnostic criteria incorporating ancillary investigations. PMID- 29578488 TI - Risk Factors Associated with Cortical Thickness and White Matter Hyperintensities in Dementia Free Okinawan Elderly. AB - BACKGROUND: Cortical gray matter (GM) and white matter (WM) deterioration are signals of neurodegeneration and increased dementia risk; however, their specific etiologies in dementia-free aging is unclear. OBJECTIVE: The objective of this study was to examine potentially modifiable risk factors of GM and WM degeneration in a well-characterized cohort of dementia-free elderly. METHODS: 96 Okinawan elderly participants (age 83.6) from the Keys to Optimal Cognitive Aging Project (KOCOA) underwent MRI and cognitive evaluation. Serum markers of inflammation (interleukin-6 (IL-6), high sensitivity C-reactive protein), cerebrovascular disease (systolic blood pressure (SBP) 140+, hemoglobin A1C (HgbA1C), total cholesterol), and essential minerals (copper (Cu), magnesium, and calcium) were examined in relation to mean cortical thickness (MCT) and white matter hyperintensities (WMH), adjusting for age and gender. Voxel-based morphometry (VBM) analyses identified relationships between regional GM density and the above markers. RESULTS: Decreased MCT was associated with SBP 140 + (p = 0.029) and increased serum IL-6 (p = 0.036), HgbA1C (p = 0.002), and Cu (p = 0.025). In VBM analyses, increased IL-6, HgbA1C, and Cu were associated with decreased GM density in temporal lobe regions. HgbA1C (p = 0.004) was associated with greater WMH volume. CONCLUSIONS: Peripheral markers of Cu, CVD risk, and inflammation are associated with MRI-markers of decreased brain health in dementia-free Okinawan elderly, with regional cortical thinning in areas involved in early accumulation of Alzheimer's disease pathology. Results identify potentially modifiable biomarkers as targets in the prevention of dementia in older individuals. PMID- 29578490 TI - Frontotemporal Dementia and Chorea Associated with a Compound Heterozygous TREM2 Mutation. AB - Frontotemporal dementia (FTD) is clinically characterized by behavioral changes, language impairment, and executive dysfunction. FTD usually belongs to the frontotemporal lobar degeneration (FTLD) disease group, and its familial forms are dominantly inherited and linked to a group of genes relevant to frontal and temporal brain pathology, such as MAPT, GRN, C9ORF72, TARDBP, CHMP2B, VCP, and FUS. However, FTD can also be associated with different clinical or pathological phenotypes caused by mutations in other genes, whose heredity can be dominant or recessive. In this work we report on a familial case of FTD characterized by behavioral changes and aphasia, very early onset and very long duration, choreic movements, and white matter lesions at magnetic resonance imaging. We performed a wide-range genetic analysis, using a next generation sequencing approach, to evaluate a number of genes involved in neurodegeneration. We found a previously unreported compound heterozygous mutation in TREM2, that is commonly associated with the recessively inherited Nasu-Hakola disease. We discuss the differential diagnosis to be taken into account in cases of FTD presenting with atypical features. PMID- 29578491 TI - The Impact of Creative Arts in Alzheimer's Disease and Dementia Public Health Education. AB - Previous research involving dramatic performances about Alzheimer's disease and dementia perception have targeted health care workers or caretakers. We examined the influence of a theater performance on the emotional affect of a general audience to determine the utility of this type of theater in large-scale public health education efforts. Our study included 147 participants that attended a self-revelatory theater performance based on the social/relationship experiences of those with dementia and those who care for them. This type of theater engages the audience and actors in a dual transformative process, supporting the emotional growth of all involved. Participants completed pre- and post performance questionnaires regarding their beliefs and feelings surrounding the topic of dementia and the importance of the Arts for educating on issues surrounding dementia care. We tested for change in emotional affect pre- and post performance using sensitivity and center of gravity statistical analyses. We found a significant change in emotional affect from an initial strong negative affect to slightly more positive/relaxed view after viewing the performance. Findings support self-revelatory theater as a resource to destigmatize preconceived notions of dementia. Large-scale community health education efforts could benefit from using this style of theater to elicit a change in audience perception of disease realities. PMID- 29578492 TI - Computer-aided planning with exact implementation into surgical technique in TKA is as accurate as intraoperative navigation. AB - BACKGROUND: Exact positioning of implants and accuracy of alignment are important parameters to provide an long survivorship of endoprostheses after total knee arthroplasty. It was suggested that an alignment within 3? from centerline provides the best long-term survivorship of TKA. Therefore, computer-assisted navigation became more important in TKAs. Another tool to improve the accuracy in TKA is the preoperative planning software. OBJECTIVE: Main goal was to determine if advantages of an intraoperative navigation system during TKA can be reached by an exact implementation of a preoperative computer-aided planning. METHODS: Based on all patients (n= 100) underwent primarily TKA in 2015 and 2016 two groups were declared: (1) conventionally operated TKA without navigation system and (2) operation with an optical navigation system. Data on age, sex, date, operative time, severe complications and preoperative vs. postoperative alignment were collected retrospectively. RESULTS: The two groups do not differ in postoperative alignment and frequency of outliers. Furthermore, there was no difference referring to complications and the length of stay in hospital, but operative time was prolonged in the navigation-assisted group. CONCLUSIONS: It can be stated that conventional surgical techniques in TKA are as accurate as navigated ones if an exact preoperative computer aided planning is implemented during surgery. PMID- 29578493 TI - Body temperature of healthy men evaluated by thermography: A study of reproducibility. AB - BACKGROUND: Thermography is a safe, painless, and efficient method for checking the temperature of the skin. OBJECTIVE: Was to assess the pattern of skin temperature of healthy men, as well as to verify the reproducibility of the method. METHODS: This cross-sectional observational study was conducted with 30 men evaluated by thermography in two moments by using an infrared camera (FLIR +T650SC(r)). The skin temperature of 24 regions of interest (ROI) was measured. RESULTS: The mean difference in temperature of 10 ROIs in the two evaluations was not statistically significant. The comparisons of the DeltaTsk between the right and left sides by the two evaluations showed no differences. The intra-class correlation coefficient (ICC) between the two moments of evaluation were statistically significant, where the dorsal measurements (Left forearm and Right dorsal arm) showed poor correlations and the others ranged from moderate to strong. Greater reproducibility was confirmed for ventral and dorsal hand ROIs; however, they presented the highest coefficient of variation (9% and 8%). CONCLUSION: There is a similarity between the temperatures of the ROIs and the reproducibility in 22 of the 24 ROIs varies from moderate to strong, showing that thermography is a reproducible method in healthy men. PMID- 29578494 TI - Patient-specific instruments' routine use over conventional total knee arthroplasty remains inconclusive: Analysis of 961 cases. AB - BACKGROUND: An increasing demand for total knee arthroplasty (TKA) has pushed innovations in the industry and created a promising new technique called patient specific instruments (PSI). Early reports had promising results such as reducing operative time, cost, and improved alignment. More recent reports are conflicting. OBJECTIVE: We aimed to evaluate bleeding, operative time, complication rates, and in-hospital stay. METHODS: A monocentric retrospective analysis was performed on a total of 961 patients that met inclusion criteria. Four different TKA Systems, two of which were performed using conventional instrumentation (CI) (n= 768) and two with PSI (n= 193) were trialed under the same conditions by three senior surgeons. Operative time, complications, bleeding, range of motion, and length of stay were analyzed. RESULTS: There was no difference in operative time (p= 0.991) and length of hospital stay (p= 0.371) between PSI and CI approaches. Complication rates were lower in the PSI group. CI patients showed less non-compensated blood loss (p< 0.001) but required more transfusions (5.8% vs. 1.5%, p= 0.014). CONCLUSIONS: There was no difference in duration of surgery, length of stay, and total blood loss when performing TKA with PSI or CI. There were fewer complications in the PSI group. It remains debatable whether these findings justify routine use of PSI in TKA. PMID- 29578495 TI - Laser Doppler: A Tool for Measuring Pancreatic Islet Microvascular Vasomotion In Vivo. AB - As a functional status of microcirculation, microvascular vasomotion is important for the delivery of oxygen and nutrients and the removal of carbon dioxide and waste products. The impairment of microvascular vasomotion might be a crucial step in the development of microcirculation-related diseases. In addition, the highly vascularized pancreatic islet is adapted to support endocrine function. In this respect, it seems possible to infer that the functional status of pancreatic islet microvascular vasomotion might affect pancreatic islet function. Analyzing the pathological changes of the functional status of pancreatic islet microvascular vasomotion may be a feasible strategy to determine contributions that pancreatic islet microcirculation makes to related diseases, such as diabetes mellitus, pancreatitis, etc. Therefore, this protocol describes using a laser Doppler blood flow monitor to determine the functional status of pancreatic islet microvascular vasomotion, and to establish parameters (including average blood perfusion, amplitude, frequency, and relative velocity of pancreatic islet microvascular vasomotion) for evaluation of the microcirculatory functional status. In a streptozotocin-induced diabetic mouse model, we observed an impaired functional status of pancreatic islet microvascular vasomotion. In conclusion, this approach for assessing pancreatic islet microvascular vasomotion in vivo may reveal mechanisms relating to pancreatic islet diseases. PMID- 29578496 TI - Focused Ion Beam Fabrication of LiPON-based Solid-state Lithium-ion Nanobatteries for In Situ Testing. AB - Solid-state electrolytes are a promising replacement for current organic liquid electrolytes, enabling higher energy densities and improved safety of lithium-ion (Li-ion) batteries. However, a number of setbacks prevent their integration into commercial devices. The main limiting factor is due to nanoscale phenomena occurring at the electrode/electrolyte interfaces, ultimately leading to degradation of battery operation. These key problems are highly challenging to observe and characterize as these batteries contain multiple buried interfaces. One approach for direct observation of interfacial phenomena in thin film batteries is through the fabrication of electrochemically active nanobatteries by a focused ion beam (FIB). As such, a reliable technique to fabricate nanobatteries was developed and demonstrated in recent work. Herein, a detailed protocol with a step-by-step process is presented to enable the reproduction of this nanobattery fabrication process. In particular, this technique was applied to a thin film battery consisting of LiCoO2/LiPON/a-Si, and has further been previously demonstrated by in situ cycling within a transmission electron microscope.

AB - This protocol offers a detailed description of a psychophysiological experiment using script-driven trauma-related imagery and standardized clinical instruments within a comparative design assessing physiological and psychopathological features of individuals with BPD. This method aims at studying the psychological and physiological effects of trauma-related dissociation. Since the psychodiagnostic classification of trauma-related disorders relies on the observation of evolutionarily determined responses to life-threat, an integrated assessment paradigm for the study of reactions to traumatic memories proposes a very appropriate methodological approach. The employed script-driven imagery paradigm uses individual recall instructions to activate trauma-related memory networks and prompt associated emotional and physiological responses. These responses are measured by means of self-rating scales and physiological assessments. During the individual recall, participants are asked to vividly imagine traumatic and everyday experiences and other situations triggered by short personalized verbal scripts they authored beforehand together with the experimenters. A wide range of affective reactions and different physiological parameters can be measured. We used this paradigm to investigate dissociative states in BPD and to find physiological and affective correlates of dissociative states. Some of the participants were having severe traumatic antecedents. To investigate different reaction patterns within the same diagnostic group, participants with different levels of traumatic histories, symptom severities, and co-morbidities should be included. By using short verbal scripts, the level of stress induced to participants is held as low as possible without affecting the validity of the object of investigation.

AB - Oxidative stress is one of the important factors in decreasing sperm quality. Developing efficient protocols for detecting reactive oxygen species (ROS) in spermatozoa is of high importance in any species, but these methods are rarely used and even less in teleost. Cryopreservation is a useful technique in aquaculture for different purposes, including gene banking and guaranteed sperm availability throughout the year. Freezing/thawing procedures could cause ROS production and damage the sperm cells. Considering the prospective damage that an excess of ROS production could cause in spermatozoa depending on their localization, here a detailed methodology to detect H2O2 and to evaluate its intracellular localization by confocal microscopy is provided. For this purpose, a combination of 3 fluorochromes (2',7'-Dichlorodihydrofluorescein diacetate (DCFH-DA), a live mitochondria stain and 4',6-Diamidino-2-phenylindole dihydrochloride (DAPI)) are used to evaluate the co-localization of H2O2 with spermatozoa nuclei or mitochondria in Solea senegalesis sperm samples.

AB - Given their potential for significant property improvements relative to their large grained counterparts, much work has been devoted to the continued development of nanocrystalline metals. Despite these efforts, the transition of these materials from the lab bench to actual applications has been blocked by the inability to produce large scale parts that retain the desired nanocrystalline microstructures. Following the development of a method proven to stabilize the nanosized grain structure to temperatures approaching that of the melting point for the given metal, the US Army Research Laboratory (ARL) has progressed to the next stage in the development of these materials - namely the production of large scale parts suitable for testing and evaluation in a range of relevant test environments. This report provides a broad overview of the ongoing efforts in the processing, characterization, and consolidation of these materials at ARL. In particular, focus is placed on the methodology used for producing the nanocrystalline metal powders, in both small and large-scale amounts, that are at the center of ongoing research efforts. PMID- 29578501 TI - Capturing the Interaction Kinetics of an Ion Channel Protein with Small Molecules by the Bio-layer Interferometry Assay. AB - The bio-layer interferometry (BLI) assay is a valuable tool for measuring protein protein and protein-small molecule interactions. Here, we first describe the application of this novel label-free technique to study the interaction of human EAG1 (hEAG1) channel proteins with the small molecule PIP2. hEAG1 channel has been recognized as potential therapeutic target because of its aberrant overexpression in cancers and a few gain-of-function mutations involved in some types of neurological diseases. We purified hEAG1 channel proteins from a mammalian stable expression system and measured the interaction with PIP2 by BLI. The successful measurement of the kinetics of binding between hEAG1 protein and PIP2 demonstrates that the BLI assay is a potential high-throughput approach used for novel small-molecule ligand screening in ion channel pharmacology. PMID- 29578500 TI - Practical Considerations in Studying Metastatic Lung Colonization in Osteosarcoma Using the Pulmonary Metastasis Assay. AB - The pulmonary metastasis assay (PuMA) is an ex vivo lung explant and closed cell culture system that permits researchers to study the biology of lung colonization in osteosarcoma (OS) by fluorescence microscopy. This article provides a detailed description of the protocol, and discusses examples of obtaining image data on metastatic growth using widefield or confocal fluorescence microscopy platforms. The flexibility of the PuMA model permits researchers to study not only the growth of OS cells in the lung microenvironment, but also to assess the effects of anti-metastatic therapeutics over time. Confocal microscopy allows for unprecedented, high-resolution imaging of OS cell interactions with the lung parenchyma. Moreover, when the PuMA model is combined with fluorescent dyes or fluorescent protein genetic reporters, researchers can study the lung microenvironment, cellular and subcellular structures, gene function, and promoter activity in metastatic OS cells. The PuMA model provides a new tool for osteosarcoma researchers to discover new metastasis biology and assess the activity of novel anti-metastatic, targeted therapies. PMID- 29578502 TI - Improvement of a Closed Chest Porcine Myocardial Infarction Model by Standardization of Tissue and Blood Sampling Procedures. AB - Myocardial ischemia reperfusion (I/R) injury contributes to almost half of the necrotic area after myocardial infarction. To date there is no approved drug to prevent or reduce myocardial I/R injury. The study and understanding of the pathophysiological mechanisms of myocardial I/R injury is essential to develop successful treatments. Large animal experiments are an important step in translational methods. The porcine model of acute myocardial infarction has been established and described by ourselves and others. We aimed to further improve the value of the model by focusing in detail on the sampling techniques for use in future experiments. Furthermore, we emphasize small but important steps that can affect the quality of the final results. To mimic the clinical situation of myocardial I/R injury, a percutaneous coronary intervention (PCI) catheter was inserted into the left anterior descending coronary artery (LAD) of an anesthetized pig. degrees degrees degrees This model mimics acute myocardial infarction and PCI treatment in humans with the possibility of accurately determining the area at risk as well as the necrotic- and viable ischemic tissue. Here the model was used to investigate the effect of a bicyclic peptide inhibitor of FXIIa. The model can also be modified to allow longer reperfusion times to study later effects of myocardial infarction. PMID- 29578503 TI - Monitoring Cell-to-cell Transmission of Prion-like Protein Aggregates in Drosophila Melanogaster. AB - Protein aggregation is a central feature of most neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Protein aggregates are closely associated with neuropathology in these diseases, although the exact mechanism by which aberrant protein aggregation disrupts normal cellular homeostasis is not known. Emerging data provide strong support for the hypothesis that pathogenic aggregates in AD, PD, HD, and ALS have many similarities to prions, which are protein-only infectious agents responsible for the transmissible spongiform encephalopathies. Prions self-replicate by templating the conversion of natively-folded versions of the same protein, causing spread of the aggregation phenotype. How prions and prion-like proteins in AD, PD, HD, and ALS move from one cell to another is currently an area of intense investigation. Here, a Drosophila melanogaster model that permits monitoring of prion-like, cell to-cell transmission of mutant huntingtin (Htt) aggregates associated with HD is described. This model takes advantage of powerful tools for manipulating transgene expression in many different Drosophila tissues and utilizes a fluorescently-tagged cytoplasmic protein to directly report prion-like transfer of mutant Htt aggregates. Importantly, the approach we describe here can be used to identify novel genes and pathways that mediate spreading of protein aggregates between diverse cell types in vivo. Information gained from these studies will expand the limited understanding of the pathogenic mechanisms that underlie neurodegenerative diseases and reveal new opportunities for therapeutic intervention. PMID- 29578504 TI - Ultrasonic Fatigue Testing in the Tension-Compression Mode. AB - Ultrasonic fatigue testing is one of a few methods which allow investigating fatigue properties in the ultra-high cycle region. The method is based on exposing the specimen to longitudinal vibrations on its resonance frequency close to 20 kHz. With use of this method, it is possible to significantly decrease the time required for the test, when compared to conventional testing devices usually working at frequencies under 200 Hz. It is also used to simulate loading of material during operation in high speed conditions, such as those experienced by components of jet engines or car turbo pumps. It is necessary to operate only in the high and ultra-high cycle region, due to the possibility of extremely high deformation rates, which can have a significant influence on the test results. Specimen shape and dimensions have to be carefully selected and calculated to fulfill the resonance condition of the ultrasonic system; thus, it is not possible to test the full components or specimens of arbitrary shape. Before each test, it is necessary to harmonize the specimen with the frequency of the ultrasonic system to compensate for deviations of the real shape from the ideal one. It is not possible to run a test until a total fracture of the specimen, since the test is automatically terminated after initiation and propagation of the crack to a certain length, when the stiffness of the system changes enough to shift the system out of the resonance frequency. This manuscript describes the process of evaluation of materials' fatigue properties at high-frequency ultrasonic fatigue loading with use of mechanical resonance at a frequency close to 20 kHz. The protocol includes a detailed description of all steps required for a correct test, including specimen design, stress calculation, harmonizing with the resonance frequency, performing the test, and final static fracture. PMID- 29578505 TI - Robust DNA Isolation and High-throughput Sequencing Library Construction for Herbarium Specimens. AB - Herbaria are an invaluable source of plant material that can be used in a variety of biological studies. The use of herbarium specimens is associated with a number of challenges including sample preservation quality, degraded DNA, and destructive sampling of rare specimens. In order to more effectively use herbarium material in large sequencing projects, a dependable and scalable method of DNA isolation and library preparation is needed. This paper demonstrates a robust, beginning-to-end protocol for DNA isolation and high-throughput library construction from herbarium specimens that does not require modification for individual samples. This protocol is tailored for low quality dried plant material and takes advantage of existing methods by optimizing tissue grinding, modifying library size selection, and introducing an optional reamplification step for low yield libraries. Reamplification of low yield DNA libraries can rescue samples derived from irreplaceable and potentially valuable herbarium specimens, negating the need for additional destructive sampling and without introducing discernible sequencing bias for common phylogenetic applications. The protocol has been tested on hundreds of grass species, but is expected to be adaptable for use in other plant lineages after verification. This protocol can be limited by extremely degraded DNA, where fragments do not exist in the desired size range, and by secondary metabolites present in some plant material that inhibit clean DNA isolation. Overall, this protocol introduces a fast and comprehensive method that allows for DNA isolation and library preparation of 24 samples in less than 13 h, with only 8 h of active hands-on time with minimal modifications. PMID- 29578506 TI - CRISPR/Cas9-mediated Targeted Integration In Vivo Using a Homology-mediated End Joining-based Strategy. AB - As a promising genome editing platform, the CRISPR/Cas9 system has great potential for efficient genetic manipulation, especially for targeted integration of transgenes. However, due to the low efficiency of homologous recombination (HR) and various indel mutations of non-homologous end joining (NHEJ)-based strategies in non-dividing cells, in vivo genome editing remains a great challenge. Here, we describe a homology-mediated end joining (HMEJ)-based CRISPR/Cas9 system for efficient in vivo precise targeted integration. In this system, the targeted genome and the donor vector containing homology arms (~800 bp) flanked by single guide RNA (sgRNA) target sequences are cleaved by CRISPR/Cas9. This HMEJ-based strategy achieves efficient transgene integration in mouse zygotes, as well as in hepatocytes in vivo. Moreover, a HMEJ-based strategy offers an efficient approach for correction of fumarylacetoacetate hydrolase (Fah) mutation in the hepatocytes and rescues Fah-deficiency induced liver failure mice. Taken together, focusing on targeted integration, this HMEJ-based strategy provides a promising tool for a variety of applications, including generation of genetically modified animal models and targeted gene therapies. PMID- 29578507 TI - Real-time Breath Analysis by Using Secondary Nanoelectrospray Ionization Coupled to High Resolution Mass Spectrometry. AB - Exhaled volatile organic compounds (VOCs) have aroused considerable interest, since they can serve as biomarkers for disease diagnosis and environmental exposure in a non-invasive manner. In this work, we present a protocol to characterize the exhaled VOCs in real time by using secondary nanoelectrospray ionization coupled to high resolution mass spectrometry (Sec-nanoESI-HRMS). The homemade Sec-nanoESI source was readily set up based on a commercial nanoESI source. Hundreds of peaks were observed in the background-subtracted mass spectra of exhaled breath, and the mass accuracy values are -4.0-13.5 ppm and -20.3-1.3 ppm in the positive and negative ion detection modes, respectively. The peaks were assigned with accurate elemental composition according to the accurate mass and isotopic pattern. Less than 30 s is used for one exhalation measurement, and it takes approximately 7 min for six replicated measurements. PMID- 29578508 TI - Regeneration of Arrayed Gold Microelectrodes Equipped for a Real-Time Cell Analyzer. AB - The label-free cell-based assay is advantageous for biochemical study because of it does not require the use of experimental animals. Due to its ability to provide more dynamic information about cells under physiological conditions than classical biochemical assays, this label-free real-time cell assay based on the electric impedance principle is attracting more attention during the past decade. However, its practical utilization may be limited due to the relatively expensive cost of measurement, in which costly consumable disposable gold microchips are used for the cell analyzer. In this protocol, we have developed a general strategy to regenerate arrayed gold microelectrodes equipped for a commercial label-free cell analyzer. The regeneration process includes trypsin digestion, rinsing with ethanol and water, and a spinning step. The proposed method has been tested and shown to be effective for the regeneration and repeated usage of commercial electronic plates at least three times, which will help researchers save on the high running cost of real-time cell assays. PMID- 29578509 TI - Real-time Analysis of Transcription Factor Binding, Transcription, Translation, and Turnover to Display Global Events During Cellular Activation. AB - Upon activation, cells rapidly change their functional programs and, thereby, their gene expression profile. Massive changes in gene expression occur, for example, during cellular differentiation, morphogenesis, and functional stimulation (such as activation of immune cells), or after exposure to drugs and other factors from the local environment. Depending on the stimulus and cell type, these changes occur rapidly and at any possible level of gene regulation. Displaying all molecular processes of a responding cell to a certain type of stimulus/drug is one of the hardest tasks in molecular biology. Here, we describe a protocol that enables the simultaneous analysis of multiple layers of gene regulation. We compare, in particular, transcription factor binding (Chromatin immunoprecipitation-sequencing (ChIP-seq)), de novo transcription (4-thiouridine sequencing (4sU-seq)), mRNA processing, and turnover as well as translation (ribosome profiling). By combining these methods, it is possible to display a detailed and genome-wide course of action. Sequencing newly transcribed RNA is especially recommended when analyzing rapidly adapting or changing systems, since this depicts the transcriptional activity of all genes during the time of 4sU exposure (irrespective of whether they are up- or downregulated). The combinatorial use of total RNA-seq and ribosome profiling additionally allows the calculation of RNA turnover and translation rates. Bioinformatic analysis of high throughput sequencing results allows for many means for analysis and interpretation of the data. The generated data also enables tracking co transcriptional and alternative splicing, just to mention a few possible outcomes. The combined approach described here can be applied for different model organisms or cell types, including primary cells. Furthermore, we provide detailed protocols for each method used, including quality controls, and discuss potential problems and pitfalls. PMID- 29578510 TI - Imaging Intermediate Filaments and Microtubules with 2-dimensional Direct Stochastic Optical Reconstruction Microscopy. AB - The cytoskeleton, composed of actin microfilaments, microtubules, and intermediate filaments (IF), plays a key role in the control of cell shape, polarity, and motility. The organization of the actin and microtubule networks has been extensively studied but that of IFs is not yet fully characterized. IFs have an average diameter of 10 nm and form a network extending throughout the cell cytoplasm. They are physically associated with actin and microtubules through molecular motors and cytoskeletal linkers. This tight association is at the heart of the regulatory mechanisms that ensure the coordinated regulation of the three cytoskeletal networks required for most cell functions. It is therefore crucial to visualize IFs alone and also together with each of the other cytoskeletal networks. However, IF networks are extremely dense in most cell types, especially in glial cells, which makes its resolution very difficult to achieve with standard fluorescence microscopy (lateral resolution of ~250 nm). Direct STochastic Optical Reconstruction Microscopy (dSTORM) is a technique allowing a gain in lateral resolution of one order of magnitude. Here, we show that lateral dSTORM resolution is sufficient to resolve the dense organization of the IF networks and, in particular, of IF bundles surrounding microtubules. Such tight association is likely to participate in the coordinated regulation of these two networks and may, explain how vimentin IFs template and stabilize microtubule organization as well as could influence microtubule dependent vesicular trafficking. More generally, we show how the observation of two cytoskeletal components with dual-color dSTORM technique brings new insight into their mutual interaction. PMID- 29578511 TI - Surgical Treatment for Benign Prostatic Hyperplasia: Holmium Laser Enucleation of the Prostate (HoLEP). AB - Benign prostatic hyperplasia (BPH) commonly occurs among elderly males. The condition causes symptoms in the lower urinary tract, thereby reducing the quality of life. BPH includes 2 major treatments: medication and surgery. Surgical treatment is often the most effective and final intervention. Holmium laser enucleation of the prostate (HoLEP), one of the most efficient surgical procedures for BPH, is conducted transurethrally. During surgery, the most important and most difficult part is to locate the surgical capsule of the prostate, which is consistent to the idea of anatomic surgery. Different skills may be needed in treating different parts of the prostate. HoLEP tends to be efficient and safe with good hemostatic properties, and able to treat bladder calculus, which may be the complications of BPH. The technique is particularly suitable for prostate of varying volumes and sizes. Indeed, HoLEP also presents certain disadvantages, such as a long learning curve and costly equipment. Regardless, this method may be the "new standard" and the excellent method for the surgical treatment of BPH. PMID- 29578512 TI - Long-term Behavioral and Reproductive Consequences of Embryonic Exposure to Low dose Toxicants. AB - Bisphenols, such as bisphenol A (BPA) and bisphenol S (BPS) are polymerizing agents widely used in the production of plastics and numerous everyday-use products. Based on their chemical structure and estradiol-like biological properties, they have been classified as endocrine disrupting compounds (EDC). Long-term exposure to EDCs, even at low doses, has been linked to various health defects including cancer, behavioral disorders and infertility, with greater vulnerability indicated during early developmental periods. Cellular and molecular studies with the genetically tractable nematode model Caenorhabditis elegans have demonstrated that exposure to BPA causes apoptosis, embryonic lethality and disruption in the DNA repair mechanisms. We have previously reported that exposure of C. elegans embryos to low doses of different bisphenols decreases fecundity. In addition, we have shown that the effects of exposure during the very early stages of development persist into adulthood as assayed by quantifying habituation behavior, a form of non-associative learning. Here, we provide detailed protocols for embryonic exposure to low-dose EDCs as well as the associated fecundity and anterior touch habituation assays, along with representative results. PMID- 29578513 TI - Puncture-Induced Iris Neovascularization as a Mouse Model of Rubeosis Iridis. AB - We describe a model of puncture-induced iris neovascularization as a general model for noninvasive evaluation of angiogenesis. The model is also relevant for targeting neovascular glaucoma, a sight-threatening complication of diabetic retinopathy. This method is based on the induction of iris vascular response by a series of self-sealing uveal punctures on BALB/c mice and takes advantage of the postpartum maturation of mouse ocular vasculature. Mouse pups undergo uveal punctures from postnatal day 12.5, when the pups naturally open their eyes, until postnatal day 24.5. Due to the transparency of the cornea, iris vasculature can be analyzed easily through time by noninvasive in vivo methods. Furthermore, the semitransparent iris of BALB/c mice can be flatmounted for detailed immunohistologic analysis with minimal non-specific background staining. In this model, angiogenesis is mainly driven by the inflammatory and plasminogen activating systems. The puncture-induced model is the first to induce iris neovascularization in small rodents, and has the advantage of allowing direct noninvasive in vivo analysis of the angiogenic process. Moreover, the model can be combined with angiogenic modulating substances, which highlights its potential in the study of angiogenesis with an in vivo perspective. PMID- 29578514 TI - Mechanical Ventilation Boot Camp Curriculum. AB - Medical management of mechanically ventilated patients is challenging to novice providers. Incorrect management of this population may lead to increased morbidity and mortality. A three-day simulation-based boot camp serves to provide one-on-one instruction with a critical care provider. These intensivists may dispense personalized immediate feedback as learners engage in hands-on practice with a real mechanical ventilator. Multiple different pathologies can be reviewed that may not be encountered in the clinical setting. Learners can visualize immediate consequences of their actions and may troubleshoot and ask questions, all while in a safe learning environment. We describe the use of human-patient simulators connected to breathing simulators and mechanical ventilators. Potential curriculum executors should be aware of the cost of the equipment and the time needed to dedicate to boot camp execution; however, this intensive interactive training has been shown to increase provider competency, knowledge, and confidence in ventilator management. This curriculum outline provides guidance on how to execute a simulation-based boot camp to train providers on the management of mechanically ventilated patients. PMID- 29578515 TI - A Bioluminescent and Fluorescent Orthotopic Syngeneic Murine Model of Androgen dependent and Castration-resistant Prostate Cancer. AB - Orthotopic tumor modeling is a valuable tool for pre-clinical prostate cancer research, as it has multiple advantages over both subcutaneous and transgenic genetically engineered mouse models. Unlike subcutaneous tumors, orthotopic tumors contain more clinically accurate vasculature, tumor microenvironment, and responses to multiple therapies. In contrast to genetically engineered mouse models, orthotopic models can be performed with lower cost and in less time, involve the use of highly complex and heterogeneous mouse or human cancer cell lines, rather that single genetic alterations, and these cell lines can be genetically modified, such as to express imaging agents. Here, we present a protocol to surgically injecting a luciferase- and mCherry-expressing murine prostate cancer cell line into the anterior prostate lobe of mice. These mice developed orthotopic tumors that were non-invasively monitored in vivo and further analyzed for tumor volume, weight, mouse survival, and immune infiltration. Further, orthotopic tumor-bearing mice were surgically castrated, leading to immediate tumor regression and subsequent recurrence, representing castration-resistant prostate cancer. Although technical skill is required to carry out this procedure, this syngeneic orthotopic model of both androgen dependent and castration-resistant prostate cancer is of great use to all investigators in the field. PMID- 29578516 TI - A Flow Cytometry-based Assay to Identify Compounds That Disrupt Binding of Fluorescently-labeled CXC Chemokine Ligand 12 to CXC Chemokine Receptor 4. AB - Pharmacological targeting of G protein-coupled receptors (GPCRs) is of great importance to human health, as dysfunctional GPCR-mediated signaling contributes to the progression of many diseases. The ligand/receptor pair CXC chemokine ligand 12 (CXCL12)/CXC chemokine receptor 4 (CXCR4) has raised significant clinical interest, for instance as a potential target for the treatment of cancer and inflammatory diseases. Small molecules as well as therapeutic antibodies that specifically target CXCR4 and inhibit the receptor's function are therefore considered to be valuable pharmacological tools. Here, a flow cytometry-based cellular assay that allows identification of compounds (e.g., small molecules) that abrogate CXCL12 binding to CXCR4, is described. Essentially, the assay relies on the competition for receptor binding between a fixed amount of fluorescently labeled CXCL12, the natural chemokine agonist for CXCR4, and unlabeled compounds. Hence, the undesirable use of radioactively labeled probes is avoided in this assay. In addition, living cells are used as the source of receptor (CXCR4) instead of cell membrane preparations. This allows easy adaptation of the assay to a plate format, which increases the throughput. This assay has been shown to be a valuable generic drug discovery assay to identify CXCR4-targeting compounds. The protocol can likely be adapted to other GPCRs, at least if fluorescently labeled ligands are available or can be generated. Prior knowledge concerning the intracellular signaling pathways that are induced upon activation of these GPCRs, is not required. PMID- 29578517 TI - Rapid Nanoprobe Signal Enhancement by In Situ Gold Nanoparticle Synthesis. AB - The use of nanoprobes such as gold, silver, silica or iron-oxide nanoparticles as detection reagents in bioanalytical assays can enable high sensitivity and convenient colorimetric readout. However, high densities of nanoparticles are typically needed for detection. The available synthesis-based enhancement protocols are either limited to gold and silver nanoparticles or rely on precise enzymatic control and optimization. Here, we present a protocol to enhance the colorimetric readout of gold, silver, silica, and iron oxide nanoprobes. It was observed that the colorimetric signal can be improved by up to a 10000-fold factor. The basis for such signal enhancement strategies is the chemical reduction of Au3+ to Au0. There are several chemical reactions that enable the reduction of Au3+ to Au0. In the protocol, Good's buffers and H2O2 are used and it is possible to favor the deposition of Au0 onto the surface of existing nanoprobes, in detriment of the formation of new gold nanoparticles. The protocol consists of the incubation of the microarray with a solution consisting of chloroauric acid and H2O2 in 2-(N-morpholino)ethanesulfonic acid pH 6 buffer following the nanoprobe-based detection assay. The enhancement solution can be applied to paper and glass-based sensors. Moreover, it can be used in commercially available immunoassays as demonstrated by the application of the method to a commercial allergen microarray. The signal development requires less than 5 min of incubation with the enhancement solution and the readout can be assessed by naked eye or low-end image acquisition devices such as a table-top scanner or a digital camera. PMID- 29578518 TI - Measuring Endoreduplication by Flow Cytometry of Isolated Tuber Protoplasts. AB - Endoreduplication, the replication of a cell's nuclear genome without subsequent cytokinesis, yields cells with increased DNA content and is associated with specialization, development and increase in cellular size. In plants, endoreduplication seems to facilitate the growth and expansion of certain tissues and organs. Among them is the tuber of potato (Solanum tuberosum), which undergoes considerable cellular expansion in fulfilling its function of carbohydrate storage. Thus, endoreduplication may play an important role in how tubers are able to accommodate this abundance of carbon. However, the cellular debris resulting from crude nuclear isolation methods of tubers, methods that can be used effectively with leaves, precludes the estimation of the tuber endoreduplication index (EI). This article presents a technique for assessing tuber endoreduplication through the isolation of protoplasts while demonstrating representative results obtained from different genotypes and compartmentalized tuber tissues. The major limitations of the protocol are the time and reagent costs required for sample preparation as well as relatively short lifespan of samples after lysis of protoplasts. While the protocol is sensitive to technical variation, it represents an improvement over traditional methods of nuclear isolation from these large specialized cells. Possibilities for improvements to the protocol such as recycling enzyme, the use of fixatives, and other alterations are proposed. PMID- 29578519 TI - Isolation and Culture of Rodent Microglia to Promote a Dynamic Ramified Morphology in Serum-free Medium. AB - Microglia represent 5 - 10% of all central nervous system (CNS) cells and are increasingly drawing attention due to their contributions during development, homeostasis, and disease. Although macrophages have been studied in detail for decades, specialized features of microglia, the tissue-resident macrophages of the CNS, have remained largely mysterious, in part due to limitations in the ability to recapitulate mature microglial properties in culture. Here, we illustrate a straightforward procedure for the rapid isolation of pure microglia from the mature rodent brain. We also describe serum-free culture conditions that support high levels of microglial viability over time. Microglia cultured under these defined-medium conditions exhibit elaborate ramified processes and dynamic surveillance behavior. We illustrate some effects of serum exposure on cultured microglia and discuss how these serum-free cultures compare to both serum-exposed cultures as well as microglia in vivo. PMID- 29578520 TI - Mobile Game-based Virtual Reality Program for Upper Extremity Stroke Rehabilitation. AB - Stroke rehabilitation requires repetitive, intensive, goal-oriented therapy. Virtual reality (VR) has the potential to satisfy these requirements. Game-based therapy can promote patients' engagement in rehabilitation therapy as a more interesting and a motivating tool. Mobile devices such as smartphones and tablet PCs can provide personalized home-based therapy with interactive communication between patients and clinicians. In this study, a mobile VR upper extremity rehabilitation program using game applications was developed. The findings from the study show that the mobile game-based VR program effectively promotes upper extremity recovery in patients with stroke. In addition, patients completed two weeks of treatment using the program without adverse effects and were generally satisfied with the program. This mobile game-based VR upper extremity rehabilitation program can substitute for some parts of the conventional therapy that are delivered one-on-one by an occupational therapist. This time-efficient, easy to implement, and clinically effective program would be a good candidate tool for tele-rehabilitation for upper extremity recovery in patients with stroke. Patients and therapists can collaborate remotely through these e-health rehabilitation programs while reducing economic and social costs. PMID- 29578521 TI - Detection of Detergent-sensitive Interactions Between Membrane Proteins. AB - Our ability to explore protein-protein interactions is the key to understanding regulatory connections in the cell. However, detection of protein-protein interactions in many cases is associated with significant experimental challenges. In particular, sorting receptors interact with their protein cargo in the lumen of the membrane compartments often in a detergent-sensitive fashion, making co-immunoprecipitation of these proteins unusable. Binding of the sorting receptor sortilin to glucose transporter GLUT4 may serve as an example of weak luminal interactions between membrane proteins. Here, we describe a fast, simple, and inexpensive assay to validate the interaction between sortilin and GLUT4. For that, we have designed and chemically synthesized the myc-tagged peptide corresponding to the potential sortilin-binding epitope in the luminal part of GLUT4. Sortilin tagged with six histidines was expressed in mammalian cells, and isolated from cell lysates using Cobalt beads. Sortilin immobilized on the beads was incubated with the peptide solution at different pH values, and the eluted material was analyzed by Western blotting. This assay can be easily adapted to study other detergent-sensitive protein-protein interactions. PMID- 29578522 TI - Histological Quantification to Determine Lung Fungal Burden in Experimental Aspergillosis. AB - The quantification of lung fungal burden is critical for the determination of the relative levels of immune protection and fungal virulence in mouse models of pulmonary fungal infection. Although multiple methods are used to assess fungal burden, quantitative polymerase chain reaction (qPCR) of fungal DNA has emerged as a technique with several advantages over previous culture-based methods. Currently, a comprehensive assessment of lung pathology, leukocyte recruitment, fungal burden, and gene expression in mice with invasive aspergillosis (IA) necessitates the use of a significant number of experimental and control animals. Here the quantification of lung histological staining to determine fungal burden using a reduced number of animals was examined in detail. Lung sections were stained to identify fungal structures with Gomori's modified methanamine silver (GMS) staining. Images were taken from the GMS-stained sections from 4 discrete fields of each formalin-fixed paraffin-embedded lung. The GMS stained areas within each image were quantified using an image analysis program, and from this quantification, the mean percentage of stained area was determined for each sample. Using this strategy, eosinophil-deficient mice exhibited decreased fungal burden and disease with caspofungin therapy, while wild-type mice with IA did not improve with caspofungin. Similarly, fungal burden in mice lacking gammadelta T cells were also improved by caspofungin, as measured by qPCR and GMS quantification. GMS quantification is therefore introduced as a method for the determination of relative lung fungal burden that may ultimately reduce the quantity of experimental animals required for comprehensive studies of invasive aspergillosis. PMID- 29578523 TI - Initial Evaluation of Antibody-conjugates Modified with Viral-derived Peptides for Increasing Cellular Accumulation and Improving Tumor Targeting. AB - Antibody-conjugates (ACs) modified with virus-derived peptides are a potentially powerful class of tumor cell delivery agents for molecular payloads used in cancer treatment and imaging due to increased cellular accumulation over current ACs. During early AC in vitro development, fluorescence techniques and radioimmunoassays are sufficient for determining intracellular localization, accumulation efficiency, and target cell specificity. Currently, there is no consensus on standardized methods for preparing cells for evaluating AC intracellular accumulation and localization. The initial testing of ACs modified with virus-derived peptides is critical especially if several candidates have been constructed. Determining intracellular accumulation by fluorescence can be affected by background signal from ACs at the cell surface and complicate the interpretation of accumulation. For radioimmunoassays, typically treated cells are fractionated and the radioactivity in different cell compartments measured. However, cell lysis varies from cell to cell and often nuclear and cytoplasmic compartments are not adequately isolated. This can produce misleading data on payload delivery properties. The intravenous injection of radiolabeled virus derived peptide-modified ACs in tumor bearing mice followed by radionuclide imaging is a powerful method for determining tumor targeting and payload delivery properties at the in vivo phase of development. However, this is a relatively recent advancement and few groups have evaluated virus-derived peptide-modified ACs in this manner. We describe the processing of treated cells to more accurately evaluate virus-derived peptide-modified AC accumulation when using confocal microscopy and radioimmunoassays. Specifically, a method for trypsinizing cells to remove cell surface bound ACs. We also provide a method for improving cellular fractionation. Lastly, this protocol provides an in vivo method using positron emission tomography (PET) for evaluating initial tumor targeting properties in tumor-bearing mice. We use the radioisotope 64Cu (t1/2 = 12.7 h) as an example payload in this protocol. PMID- 29578524 TI - Sampling Strategies and Processing of Biobank Tissue Samples from Porcine Biomedical Models. AB - In translational medical research, porcine models have steadily become more popular. Considering the high value of individual animals, particularly of genetically modified pig models, and the often-limited number of available animals of these models, establishment of (biobank) collections of adequately processed tissue samples suited for a broad spectrum of subsequent analyses methods, including analyses not specified at the time point of sampling, represent meaningful approaches to take full advantage of the translational value of the model. With respect to the peculiarities of porcine anatomy, comprehensive guidelines have recently been established for standardized generation of representative, high-quality samples from different porcine organs and tissues. These guidelines are essential prerequisites for the reproducibility of results and their comparability between different studies and investigators. The recording of basic data, such as organ weights and volumes, the determination of the sampling locations and of the numbers of tissue samples to be generated, as well as their orientation, size, processing and trimming directions, are relevant factors determining the generalizability and usability of the specimen for molecular, qualitative, and quantitative morphological analyses. Here, an illustrative, practical, step-by-step demonstration of the most important techniques for generation of representative, multi-purpose biobank specimen from porcine tissues is presented. The methods described here include determination of organ/tissue volumes and densities, the application of a volume-weighted systematic random sampling procedure for parenchymal organs by point-counting, determination of the extent of tissue shrinkage related to histological embedding of samples, and generation of randomly oriented samples for quantitative stereological analyses, such as isotropic uniform random (IUR) sections generated by the "Orientator" and "Isector" methods, and vertical uniform random (VUR) sections.

AB - Infiltration of immune cells in the subcutaneous and visceral adipose tissue (AT) deposits leads to a low-grade inflammation contributing to the development of obesity-associated complications such as type 2 diabetes. To quantitatively and qualitatively investigate the immune cell subsets in human AT deposits, we have developed a flow cytometry approach. The stromal vascular fraction (SVF), containing the immune cells, is isolated from subcutaneous and visceral AT biopsies by collagenase digestion. Adipocytes are removed after centrifugation. The SVF cells are stained for multiple membrane-bound markers selected to differentiate between immune cell subsets and analyzed using flow cytometry. As a result of this approach, pro- and anti-inflammatory macrophage subsets, dendritic cells (DCs), B-cells, CD4+ and CD8+ T-cells, and NK cells can be detected and quantified. This method gives detailed information about immune cells in AT and the amount of each specific subset. Since there are numerous fluorescent antibodies available, our flow cytometry approach can be adjusted to measure various other cellular and intracellular markers of interest.

AB - Ischemic stroke leads to vasogenic cerebral edema and subsequent primary brain injury, which is mediated through destruction of the blood-brain barrier (BBB). Rats with induced ischemic stroke were established and used as in vivo models to investigate the functional integrity of the BBB. Spectrophotometric detection of Evans blue (EB) in the brain samples with ischemic injury could provide reliable justification for the research and development of novel therapeutic modalities. This method generates reproducible results, and is applicable in any laboratory without a need for special equipment. Here, we present a visualized and technical guideline on the detection of the extravasation of EB following induction of ischemic stroke in rats. PMID- 29578527 TI - Adult Mouse DRG Explant and Dissociated Cell Models to Investigate Neuroplasticity and Responses to Environmental Insults Including Viral Infection. AB - This protocol describes an ex vivo model of mouse-derived dorsal root ganglia (DRG) explant and in vitro DRG-derived co-culture of dissociated sensory neurons and glial satellite cells. These are useful and versatile models to investigate a variety of biological responses associated with physiological and pathological conditions of the peripheral nervous system (PNS) ranging from neuron-glial interaction, neuroplasticity, neuroinflammation, and viral infection. The usage of DRG explant is scientifically advantageous compared to simplistic single cells models for multiple reasons. For instance, as an organotypic culture, the DRG explant allows ex vivo transfer of an entire neuronal network including the extracellular microenvironment that play a significant role in all the neuronal and glial functions. Further, DRG explants can also be maintained ex vivo for several days and the culture conditions can be perturbed as desired. In addition, the harvested DRG can be further dissociated into an in vitro co-culture of primary sensory neurons and satellite glial cells to investigate neuronal-glial interaction, neuritogenesis, axonal cone interaction with the extracellular microenvironment, and more general, any aspect associated with the neuronal metabolism. Therefore, the DRG-explant system offers a great deal of flexibility to study a wide array of events related to biological, physiological, and pathological conditions in a cost-effective manner. PMID- 29578528 TI - Preparation of DMMTAV and DMDTAV Using DMAV for Environmental Applications: Synthesis, Purification, and Confirmation. AB - Dimethylated thioarsenicals such as dimethylmonothioarsinic acid (DMMTAV) and dimethyldithioarsinic acid (DMDTAV), which are produced by the metabolic pathway of dimethylarsinic acid (DMAV) thiolation, have been recently found in the environment as well as human organs. DMMTAV and DMDTAV can be quantified to determine the ecological effects of dimethylated thioarsenicals and their stability in environmental media. The synthesis method for these compounds is unstandardized, making replicating previous studies challenging. Furthermore, there is a lack of information about storage techniques, including storage of compounds without species transformation. Moreover, because only limited information about synthesis methods is available, there may be experimental difficulties in synthesizing standard chemicals and performing quantitative analysis. The protocol presented herein provides a practically modified synthesis method for the dimethylated thioarsenicals, DMMTAV and DMDTAV, and will help in the quantification of species separation analysis using high performance liquid chromatography in conjunction with inductively coupled plasma mass spectrometry (HPLC-ICP-MS). The experimental steps of this procedure were modified by focusing on the preparation of chemical reagents, filtration methods, and storage. PMID- 29578529 TI - Moving Upwards: A Simple and Flexible In Vitro Three-dimensional Invasion Assay Protocol. AB - Although 3D invasion assays have been developed, the challenge remains to study cells without affecting the integrity of their microenvironment. Traditional 3D assays such as the Boyden Chamber require that cells are displaced from the original culture location and moved to a new environment. Not only does this disrupt the cellular processes that are intrinsic to the microenvironment, but it often results in a loss of cells. These problems are especially challenging when dealing with cells that are either rare, or extremely sensitive to their microenvironment. Here, we describe the development of a 3D invasion assay that avoids both concerns. In this assay, cells are plated within a small well and an ECM matrix containing a chemoattractant is laid atop the cells. This requires no cell displacement, and allows the cells to invade upwards into the matrix. In this assay, cell invasion as well as cell morphology can be assessed within the collagen gel. Using this assay, we characterize the invasive capacity of rare and sensitive cells; the hybrid cells resulting from fusion between breast cancer cells MCF7 and mesenchymal/multipotent stem/stroma cells (MSCs).

AB - Autophagy and immunity share the property of being auto-protective for the organism. Autophagy is an important degradation pathway that buffers nutrient deprivation by recycling macromolecules in organisms from yeast to man. Perturbations in autophagy are associated with inflammation and cancer development. Emerging studies have characterized the molecular details regarding how autophagy is controlled by immune cells. Among these, dendritic cells (DCs) are one of the most potent professional antigen-presenting cells critical for the activation of naive T cells to maintain immune tolerance and drive protective immunity to infection and cancer. DCs undergo functional maturation that can either lead to an immunostimulatory phenotype, as in the context of infection, or to a tolerogenic phenotype associated with immunosuppression to self-antigens, as well as to cancer. An increasing number of recent studies has characterized the involvement of autophagy in DC functions in various physiological and pathological contexts. Here, we provide a comprehensive review of these outcomes and discuss the limitation of the models used and the forefront of the knowledge concerning the crosstalk between autophagy and DC biology. PMID- 29578532 TI - Critical role of OX40 signaling in the TCR-independent phase of human and murine thymic Treg generation. AB - Regulatory T cells (Tregs) play a pivotal role in immune-tolerance, and loss of Treg function can lead to the development of autoimmunity. Natural Tregs generated in the thymus substantially contribute to the Treg pool in the periphery, where they suppress self-reactive effector T cells (Teff) responses. Recently, we showed that OX40L (TNFSF4) is able to drive selective proliferation of peripheral Tregs independent of canonical antigen presentation (CAP independent) in the presence of low-dose IL-2. Therefore, we hypothesized that OX40 signaling might be integral to the TCR-independent phase of murine and human thymic Treg (tTreg) development. Development of tTregs is a two-step process: Strong T-cell receptor (TCR) signals in combination with co-signals from the TNFRSF members facilitate tTreg precursor selection, followed by a TCR independent phase of tTreg development in which their maturation is driven by IL 2. Therefore, we investigated whether OX40 signaling could also play a critical role in the TCR-independent phase of tTreg development. OX40-/- mice had significantly reduced numbers of CD25-Foxp3low tTreg precursors and CD25+Foxp3+ mature tTregs, while OX40L treatment of WT mice induced significant proliferation of these cell subsets. Relative to tTeff cells, OX40 was expressed at higher levels in both murine and human tTreg precursors and mature tTregs. In ex vivo cultures, OX40L increased tTreg maturation and induced CAP-independent proliferation of both murine and human tTregs, which was mediated through the activation of AKT-mTOR signaling. These novel findings show an evolutionarily conserved role for OX40 signaling in tTreg development and proliferation, and might enable the development of novel strategies to increase Tregs and suppress autoimmunity.Cellular and Molecular Immunology advance online publication, 26 March 2018; doi:10.1038/cmi.2018.8. PMID- 29578533 TI - MicroRNA-663 induces immune dysregulation by inhibiting TGF-beta1 production in bone marrow-derived mesenchymal stem cells in patients with systemic lupus erythematosus. AB - Mesenchymal stem cells (MSCs) are critical for immune regulation. Although several microRNAs (miRNAs) have been shown to participate in autoimmune pathogenesis by affecting lymphocyte development and function, the roles of miRNAs in MSC dysfunction in autoimmune diseases remain unclear. Here, we show that patients with systemic lupus erythematosus (SLE) display a unique miRNA signature in bone marrow-derived MSCs (BMSCs) compared with normal controls, among which miR-663 is closely associated with SLE disease activity. MiR-663 inhibits the proliferation and migration of BMSCs and impairs BMSC-mediated downregulation of follicular T helper (Tfh) cells and upregulation of regulatory T (Treg) cells by targeting transforming growth factor beta1 (TGF-beta1). MiR-663 overexpression weakens the therapeutic effect of BMSCs, while miR-663 inhibition improves the remission of lupus disease in MRL/lpr mice. Thus, miR-663 is a key mediator of SLE BMSC regulation and may serve as a new therapeutic target for the treatment of lupus.Cellular and Molecular Immunology advance online publication, 26 March 2018; doi:10.1038/cmi.2018.1.

AB - Cells use feedback regulation to ensure robust growth despite fluctuating demands for resources and differing environmental conditions. However, the expression of foreign proteins from engineered constructs is an unnatural burden that cells are not adapted for. Here we combined RNA-seq with an in vivo assay to identify the major transcriptional changes that occur in Escherichia coli when inducible synthetic constructs are expressed. We observed that native promoters related to the heat-shock response activated expression rapidly in response to synthetic expression, regardless of the construct. Using these promoters, we built a dCas9 based feedback-regulation system that automatically adjusts the expression of a synthetic construct in response to burden. Cells equipped with this general-use controller maintained their capacity for native gene expression to ensure robust growth and thus outperformed unregulated cells in terms of protein yield in batch production. This engineered feedback is to our knowledge the first example of a universal, burden-based biomolecular control system and is modular, tunable and portable.

PMID- 29578538 TI - Combinatorial inhibition of PTPN12-regulated receptors leads to a broadly effective therapeutic strategy in triple-negative breast cancer. AB - Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer diagnosed in more than 200,000 women each year and is recalcitrant to targeted therapies. Although TNBCs harbor multiple hyperactive receptor tyrosine kinases (RTKs), RTK inhibitors have been largely ineffective in TNBC patients thus far. We developed a broadly effective therapeutic strategy for TNBC that is based on combined inhibition of receptors that share the negative regulator PTPN12. Previously, we and others identified the tyrosine phosphatase PTPN12 as a tumor suppressor that is frequently inactivated in TNBC. PTPN12 restrains several RTKs, suggesting that PTPN12 deficiency leads to aberrant activation of multiple RTKs and a co-dependency on these receptors. This in turn leads to the therapeutic hypothesis that PTPN12-deficient TNBCs may be responsive to combined RTK inhibition. However, the repertoire of RTKs that are restrained by PTPN12 in human cells has not been systematically explored. By methodically identifying the suite of RTK substrates (MET, PDGFRbeta, EGFR, and others) inhibited by PTPN12, we rationalized a combination RTK-inhibitor therapy that induced potent tumor regression across heterogeneous models of TNBC. Orthogonal approaches revealed that PTPN12 was recruited to and inhibited these receptors after ligand stimulation, thereby serving as a feedback mechanism to limit receptor signaling. Cancer-associated mutation of PTPN12 or reduced PTPN12 protein levels diminished this feedback mechanism, leading to aberrant activity of these receptors. Restoring PTPN12 protein levels restrained signaling from RTKs, including PDGFRbeta and MET, and impaired TNBC survival. In contrast with single agents, combined inhibitors targeting the PDGFRbeta and MET receptors induced the apoptosis in TNBC cells in vitro and in vivo. This therapeutic strategy resulted in tumor regressions in chemo-refractory patient-derived TNBC models. Notably, response correlated with PTPN12 deficiency, suggesting that impaired receptor feedback may establish a combined addiction to these proto-oncogenic receptors. Taken together, our data provide a rationale for combining RTK inhibitors in TNBC and other malignancies that lack receptor-activating mutations. PMID- 29578539 TI - Targeting hepatic glutaminase activity to ameliorate hyperglycemia. AB - Glucagon levels increase under homeostatic, fasting conditions, promoting the release of glucose from the liver by accelerating the breakdown of glycogen (also known as glycogenolysis). Glucagon also enhances gluconeogenic flux, including from an increase in the hepatic consumption of amino acids. In type 2 diabetes, dysregulated glucagon signaling contributes to the elevated hepatic glucose output and fasting hyperglycemia that occur in this condition. Yet, the mechanism by which glucagon stimulates gluconeogenesis remains incompletely understood. Contrary to the prevailing belief that glucagon acts primarily on cytoplasmic and nuclear targets, we find glucagon-dependent stimulation of mitochondrial anaplerotic flux from glutamine that increases the contribution of this amino acid to the carbons of glucose generated during gluconeogenesis. This enhanced glucose production is dependent on protein kinase A (PKA) and is associated with glucagon-stimulated calcium release from the endoplasmic reticulum, activation of mitochondrial alpha-ketoglutarate dehydrogenase, and increased glutaminolysis. Mice with reduced levels of hepatic glutaminase 2 (GLS2), the enzyme that catalyzes the first step in glutamine metabolism, show lower glucagon-stimulated glutamine-to-glucose flux in vivo, and GLS2 knockout results in higher fasting plasma glucagon and glutamine levels with lower fasting blood glucose levels in insulin-resistant conditions. As found in genome-wide association studies (GWAS), human genetic variation in the region of GLS2 is associated with higher fasting plasma glucose; here we show in human cryopreserved primary hepatocytes in vitro that these natural gain-of-function missense mutations in GLS2 result in higher glutaminolysis and glucose production. These data emphasize the importance of gluconeogenesis from glutamine, particularly in pathological states of increased glucagon signaling, while suggesting a possible new therapeutic avenue to treat hyperglycemia.

AB - Biodegradable vascular scaffolds (BVS) are novel treatments for obstructive atherosclerotic cardiovascular disease that have been developed to overcome the limitations of traditional metallic drug-eluting stents (DES). The mechanical properties of bioabsorbable polymers used for the production of novel BVS are a key consideration for the clinical translation of this emerging technology. Herein, we describe the engineering of an in situ light-activated vascular scaffold (ILVS) comprised of a biodegradable citric acid-based elastomeric polymer, referred to as methacrylated poly-diol citrate (mPDC), and a diazeniumdiolate chitosan nitric oxide donor (chitoNO). In vitro studies demonstrate that the mechanical properties of the ILVS can be tailored to meet or exceed those of commercially available self-expanding bare metal stents (BMS). The radial compression strength of the ILVS is higher than that of a BMS despite undergoing degradation at physiologic conditions for 7 months. ILVS containing chitoNO provides sustained supraphysiologic levels of NO release. Lastly, ILVS were successfully cast in porcine arteries ex vivo using a custom designed triple balloon catheter, demonstrating translational potential. In conclusion, these data demonstrate the ability of an ILVS to provide tunable mechanical properties and drug-delivery capabilities for the vasculature, and thereby support mPDC as a promising material for the development of novel BVS platforms.

PMID- 29578544 TI - The orange spotted cockroach (Blaptica dubia, Serville 1839) is a permissive experimental host for Francisella tularensis. AB - Francisella tularensis is a zoonotic bacterial pathogen that causes severe disease in a wide range of host animals, including humans. Well-developed murine models of F. tularensis pathogenesis are available, but they do not meet the needs of all investigators. However, researchers are increasingly turning to insect host systems as a cost-effective alternative that allows greater increased experimental throughput without the regulatory requirements associated with the use of mammals in biomedical research. Unfortunately, the utility of previously described insect hosts is limited because of temperature restriction, short lifespans, and concerns about the immunological status of insects mass-produced for other purposes. Here, we present a novel host species, the orange spotted (OS) cockroach (Blaptica dubia), that overcomes these limitations and is readily infected by F. tularensis. Intrahemocoel inoculation was accomplished using standard laboratory equipment and lethality was directly proportional to the number of bacteria injected. Progression of infection differed in insects housed at low and high temperatures and F. tularensis mutants lacking key virulence components were attenuated in OS cockroaches. Finally, antibiotics were delivered to infected OS cockroaches by systemic injection and controlled feeding; in the latter case, protection correlated with oral bioavailability in mammals. Collectively, these results demonstrate that this new host system provides investigators with a new tool capable of interrogating F. tularensis virulence and immune evasion in situations where mammalian models are not available or appropriate, such as undirected screens of large mutant libraries. PMID- 29578546 TI - Revisiting random walk based sampling in networks: evasion of burn-in period and frequent regenerations. AB - Background: In the framework of network sampling, random walk (RW) based estimation techniques provide many pragmatic solutions while uncovering the unknown network as little as possible. Despite several theoretical advances in this area, RW based sampling techniques usually make a strong assumption that the samples are in stationary regime, and hence are impelled to leave out the samples collected during the burn-in period. Methods: This work proposes two sampling schemes without burn-in time constraint to estimate the average of an arbitrary function defined on the network nodes, for example, the average age of users in a social network. The central idea of the algorithms lies in exploiting regeneration of RWs at revisits to an aggregated super-node or to a set of nodes, and in strategies to enhance the frequency of such regenerations either by contracting the graph or by making the hitting set larger. Our first algorithm, which is based on reinforcement learning (RL), uses stochastic approximation to derive an estimator. This method can be seen as intermediate between purely stochastic Markov chain Monte Carlo iterations and deterministic relative value iterations. The second algorithm, which we call the Ratio with Tours (RT) estimator, is a modified form of respondent-driven sampling (RDS) that accommodates the idea of regeneration. Results: We study the methods via simulations on real networks. We observe that the trajectories of RL-estimator are much more stable than those of standard random walk based estimation procedures, and its error performance is comparable to that of respondent-driven sampling (RDS) which has a smaller asymptotic variance than many other estimators. Simulation studies also show that the mean squared error of RT estimator decays much faster than that of RDS with time. Conclusion: The newly developed RW based estimators (RL- and RT-estimators) allow to avoid burn-in period, provide better control of stability along the sample path, and overall reduce the estimation time. Our estimators can be applied in social and complex networks.

PMID- 29578548 TI - Orientation Uncertainty Characteristics of Some Pose Measuring Systems. AB - We investigate the performance of pose measuring systems which determine an object's pose from measurement of a few fiducial markers attached to the object. Such systems use point-based, rigid body registration to get the orientation matrix. Uncertainty in the fiducials' measurement propagates to the uncertainty of the orientation matrix. This orientation uncertainty then propagates to points on the object's surface. This propagation is anisotropic, and the direction along which the uncertainty is the smallest is determined by the eigenvector associated with the largest eigenvalue of the orientation data's covariance matrix. This eigenvector in the coordinate frame defined by the fiducials remains almost fixed for any rotation of the object. However, the remaining two eigenvectors vary widely and the direction along which the propagated uncertainty is the largest cannot be determined from the object's pose. Conditions that result in such a behavior and practical consequences of it are presented. PMID- 29578549 TI - Patient Perceptions of Readmission Risk: An Exploratory Survey. AB - Interventions to prevent readmissions often rely upon patient participation to be successful. We surveyed 895 general medicine patients slated for hospital discharge to (1) assess patient attitudes surrounding readmission, (2) ascertain whether these attitudes were associated with actual readmission, and (3) determine whether patients can estimate their own readmission risk. Actual readmissions and other clinical variables were captured from administrative data and linked to individual survey responses. We found that actual readmissions were not correlated with patients' interest in preventing readmission, sense of control over readmission, or intent to follow discharge instructions. However, patients were able to predict their own readmissions (P = .005) even after adjusting for predicted readmission rate, race, sex, age, and payer. Reassuringly, over 80% of respondents reported that they would be frustrated or disappointed to be readmitted and almost 90% indicated that they planned to follow all of their discharge instructions. Whether assessing patient-perceived readmission risk might help to target preventive interventions warrants further study. PMID- 29578550 TI - Training Residents in Hospital Medicine: The Hospitalist Elective National Survey. AB - As the field of hospital medicine expands, internal medicine residency programs can play a role in preparing future hospitalists. To date, little is known of the prevalence and characteristics of hospitalist-focused resident rotations. We surveyed the largest 100 Internal Medicine Residency Programs to better understand the prevalence, objectives, and structure of hospitalist-focused rotations in the United States. Residency leaders from 82 programs responded (82%). The prevalence of hospitalist-focused rotations was 50% (41/82) with an additional 9 programs (11%) planning to start one. Of these 41 rotations, 85% were elective rotations and 15% were mandatory rotations. Rotations involved clinical responsibilities, and most programs incorporated nonclinical curricular activities such as teaching, research, and work on quality improvement and patient safety. Respondents noted that their programs promoted autonomy, mentorship, and "real-world" hospitalist experience. Hospitalist-focused rotations may supplement traditional inpatient rotations and teach skills that facilitate the transition from residency to a career in hospital medicine. PMID- 29578551 TI - The Influence of Hospitalist Continuity on the Likelihood of Patient Discharge in General Medicine Patients. AB - Hospitalists responsible for specific inpatients may change during their hospitalization. To measure the association of hospitalist continuity with the adjusted daily discharge probability, 6,405 admissions (38,967 patientdays, 5,208 patients) to a general medicine service at a tertiary care teaching hospital in 2015 were investigated. Continuity was measured as the consecutive number of days including weekends-a hospitalist treated a particular team of patients. After accounting for important covariables, discharge probability increased significantly with hospitalist continuity; the adjusted daily discharge probabilities for an average patient with a new physician vs. one on service for 4 continuous weeks were 18.1% and 25.7%, respectively (P < .001). Hospitalist continuity did not influence hospital mortality. Increasing hospitalist continuity could decrease hospital length of stay. PMID- 29578552 TI - Focusing on Inattention: The Diagnostic Accuracy of Brief Measures of Inattention for Detecting Delirium. AB - BACKGROUND: Delirium is frequently missed in most clinical settings. Brief delirium assessments are needed. OBJECTIVE: To determine the diagnostic accuracy of reciting the months of year backwards (MOTYB) from December to July (MOTYB-6) and December to January (MOTYB-12) for delirium as diagnosed by a psychiatrist and to explore the diagnostic accuracies of the following other brief attention tasks: (1) spell the word "LUNCH" backwards, (2) recite the days of the week backwards, (3) 10-letter vigilance "A" task, and (4) 5 picture recognition task. DESIGN: Preplanned secondary analysis of a prospective observational study. SETTING: Emergency department located within an academic, tertiary care hospital. PARTICIPANTS: 234 acutely ill patients who were =65 years old. MEASUREMENTS: The inattention tasks were administered by a physician. The reference standard for delirium was a comprehensive psychiatrist assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. Sensitivities and specificities were calculated. RESULTS: Making any error on the MOTYB-6 task had a sensitivity of 80.0% (95% confidence interval [CI], 60.9% 91.1%) and specificity of 57.1% (95% CI, 50.4%- 63.7%). Making any error on the MOTYB-12 task had a sensitivity of 84.0% (95% CI, 65.4%-93.6%) and specificity of 51.9% (95% CI, 45.2%-58.5%). The best combination of sensitivity and specificity was reciting the days of the week backwards task; if the patient made any error, this was 84.0% (95% CI, 65.4%-93.6%) sensitive and 81.9% (95% CI, 76.1%-86.5%) specific. CONCLUSIONS: MOTYB-6 and MOTYB-12 had very good sensitivities but had modest specificities for delirium, limiting their use as a standalone assessment. Reciting the days of the week backwards appeared to have the best combination of sensitivity and specificity for delirium. PMID- 29578554 TI - It Is What It Is... For Now. PMID- 29578553 TI - Trends in Inpatient Admission Comorbidity and Electronic Health Data: Implications for Resident Workload Intensity. AB - In the era of duty hour regulations, there is increasing concern regarding resident workload compression. We conducted a retrospective, observational assessment of all internal medicine resident admissions to a Veterans Affairs hospital over a 15-year period to evaluate several admission components that impact resident workload and workload intensity, including electronic health record (EHR) data burden and patient comorbidity. A total of 67,346 admissions were included in the analysis. Mean patient comorbidity, as measured by the Charlson Comorbidity Index, increased throughout the study period. EHR data burden, measured by numbers of notes, medications, and discharge summaries available per patient at the time of admission, also increased over the study period. These findings suggest that EHR data burden and comorbidity have increased over time, which impacts resident workload in the era of duty hour restrictions. PMID- 29578555 TI - Multifunctional trastuzumab-chlorin e6 conjugate for the treatment of HER2 positive human breast cancer. AB - Effective penetration and targeted delivery of anticancer drugs into tumor tissues are limiting factors for achieving enhanced therapeutic efficacy. In order to overcome the disadvantages of antibody therapy (limited penetration efficacy into tumor tissues) and photodynamic therapy (low targeting efficiency) on the treatment of HER2-positive human breast cancer simultaneously, an antibody and photosensitizer combined Trastuzumab-chlorin e6 conjugate (TMPC) was synthesized. TMPC exhibits high singlet oxygen generation under laser irradiation. In vitro data show that TMPC has specific HER2 selective interactions, and ROS generation ability upon laser irradiation induces significant cell death in HER2-positive breast cancer cells. The enhanced tissue penetration ability and tissue access of TMPC resulting from local tissue destruction by ROS generated from Ce6 is also demonstrated in breast cancer tissue blocks. The enhanced ability of TMPC is supported by in vivo fluorescence images of SK-BR-3 (HER2-positive cancer cells) tumor-bearing mice. The in vivo test demonstrates approximately 6-fold enhanced accumulation of TMPC in xenograft tumors with a longer retention time compared to that of the PEG-Ce6 conjugate at 24 h. Thus, trastuzumab and photosensitizer conjugation brings synergistic effects for HER2 selective targeting, where TMPC enhanced tumor tissue penetration improves tumor tissue access and responsiveness of trastuzumab in HER2 overexpressing breast cancer.

The NiCo2S4 nanoflake electrode exhibited a high specific capacitance of 1722 F g-1 (specific capacity 688.8 C g-1) at a current density of 1 A g-1 and an excellent cycling stability (capacity retention of 98.8% after 10 000 cycles). The as-fabricated asymmetric supercapacitor based on NiCo2S4 nanoflakes and activated carbon electrodes revealed a high energy density of 38.3 W h kg-1 and a high power density of 8.0 kW kg-1 with a capacitance retention of 91.5% and a coulombic efficiency of 95.6% after 5000 cycles, highlighting its great potential for practical supercapacitor applications. PMID- 29578561 TI - Comparing winter-time herbicide behavior and exports in urban, rural, and mixed use watersheds. AB - The presence of pesticides in streams in winter, five to six years following bans on their municipal use suggests that complicated transport behaviour, such as subsurface retention and/or accumulation of pesticides and its release during storms, could be important for understanding recovery time frames following bans or legislation that aim to reduce chemical inputs. We investigated late fall and winter dynamics of four herbicides in paired urban and rural watersheds in Toronto, Canada during rainfall and snowmelt. The range of average concentrations and loads of the sum of atrazine, metolachlor, 2,4-D and mecoprop overlapped in the two types of watersheds, with slightly higher average concentrations in the rural watershed. Relatively consistent herbicide concentration-discharge patterns (i.e. dilution) were observed in the urban sub-watersheds during rainfall, while concentration-discharge patterns were much more variable in the rural watershed. This suggests relatively uniform transport pathways across the urban sub watersheds, compared to the rural watershed. Concentration-discharge patterns of the neutral herbicides atrazine and metolachlor were similar in both watersheds during snowmelt, though varying discharge patterns resulted in divergent timings of peak concentrations. In contrast, the acidic pesticides 2,4-D and mecoprop, which are primarily associated with urban uses, showed much more variable behavior across both watersheds and merit further investigation. Overall, this work highlights the need to consider pesticide dynamics throughout the year in order to more thoroughly assess the long-term efficacy of legislation governing their use. PMID- 29578563 TI - Functionalization of MOFs via a mixed-ligand strategy: enhanced CO2 uptake by pore surface modification. AB - A new Zn(ii) metal-organic framework (MOF) [Me2NH2][Zn2(BDPP)(HTZ)].4DMF (1) (H4BDPP = 3,5-bis(3,5-dicarboxylphenyl)pyridine, HTZ = 1H-tetrazole) has been constructed under solvothermal conditions by using a mixed-ligand strategy. Structural analysis demonstrates that 1 is a 3D framework based on four kinds of secondary building units (SBUs), which presents a rare structure constructed from quaternary SBUs and shows an uncommon (3,3,4,6)-connected topology. In particular, 1 contains two shapes of 1D open channels with suitable pore sizes, high porosity, and a highly polar pore system decorated with uncoordinated N atoms and carboxylic O atoms, providing a good environment for selective adsorption of CO2. Inspired by the structure of 1 and reticular chemistry, 5 amino-1H-tetrazole (ATZ) was used to replace 1H-tetrazole to enhance CO2 sorption capacity by pore surface modification; as a result, an amino-functionalized MOF, [Me2NH2][Zn2(BDPP)(ATZ)].4DMF (1-NH2) was successfully built. 1-NH2 exhibits multipoint interactions between the CO2 molecules and the framework, resulting in better CO2 uptake and selectivity for CO2 over CH4 than 1. PMID- 29578567 TI - An inorganic-organic hybrid supramolecular framework as a high-performance anode for lithium-ion batteries. AB - Herein, an excellent anode was achieved for a lithium-ion battery based on a polyoxometalate-organic framework [Ni5(OH)3(trzS)3(en)(H2O)(B-alpha-PW9O34)] for the first time. It can deliver a capacity of 710 mA h g-1 at 100 mA g-1 after 50 cycles and a high capacity retention of 82.2% after 500 cycles at a high rate of 800 mA g-1, which is supposed to be due to the unique porous characteristic and high chemical stability of the proposed anode. The higher capacity was ascribed to Ni and W of the building unit taking part in lithium storage. PMID- 29578568 TI - A facile modular approach to the 2D oriented assembly MOF electrode for non enzymatic sweat biosensors. AB - The preparation of ordered metal organic frameworks (MOFs) will be a critical process for MOF-based nanoelectrodes in the future. In this work, we develop a novel approach to fabricating a type of MOF electrode based on flexible amino functionalized graphene paper modified with 2D oriented assembly of Cu3(btc)2 nanocubes via facile interfacial synthesis and an effective dip-coating method. One interesting finding is that 2D arrays of Cu3(btc)2 nanocubes at oil-water interfaces can be transferred on amino-functionalized graphene paper, leading to a densely packed monolayer of Cu3(btc)2 nanocubes with a uniform size loaded on the paper electrode. The electrode demonstrates a variety of excellent sensing performances toward sweat lactate and glucose and has been applied in a non enzymatic electrochemical biosensing platform for the first time. The modular nature of this approach to assembling MOF nanocrystals will provide new insight into the design of MOF-based electrodes for a wide range of applications in biosensing instruments, wearable electronics, and lab-on-a-chip devices.

Improving their life situation towards full participation in society is crucial. As a health strategy, rehabilitation can improve func-tioning, quality of life and participation in society. However, rehabilitation services in Indonesia need improvement. Making a situation analysis of rehabilitation services and their provision in the country is a pre-requisite to taking any action towards improvement. This paper compiles available data related to disability and rehabilitation services in Indonesia, using the Rehabilitation Services Assessment Tool (RSAT) as a framework. Gaps in provision were analysed, resulting in the compilation of a list of generic recommendations to improve rehabilitation services in the country. Indonesia faces many challenges in rehabilitation services, including the health workforce and the provision of services. This situation analysis and list of generic recommendations may be used in further discussions with relevant stakeholders in the country to develop a national strategy to strengthen rehabilitation services. PMID- 29578571 TI - Optimal model-based control of non-viral siRNA delivery. AB - Further quantitative understanding of the biological effects and mechanisms involved in cellular and intracellular delivery of nucleic acid materials is required to produce clinical applications of gene therapy. Several modeling approaches have been used in this field; however, a comprehensive approach that integrates all the key pharmacological issues into a holistic framework that is applicable for in vivo conditions is still lacking. This contribution presents a pharmacokinetic/pharmacodynamic model-based control study of non-viral siRNA delivery describing the dynamics of the delivery process and takes into account the main multi-objective optimization issues such as efficacy and toxicity, as well as the effect of uncertainty in cell doubling time. The methodology developed in this work is used to predict the optimal dosage injection rate and optimal intracellular exposure of siRNAs in order to improve the pharmacological effects before cell division occurs. The present analysis successfully provides quantitative predictions of non-viral siRNA activity paving the path for further experimental work to probe more efficient delivery systems. PMID- 29578572 TI - Physiological characterization and quantitative proteomic analyses of metabolically engineered E. coli K4 strains with improved pathways for capsular polysaccharide biosynthesis. AB - Among capsulated bacteria, some produce polysaccharides with unique properties that have been shown to possess relevant industrial applications and commercial value. The capsular polysaccharide (CPS) produced by Escherichia coli K4 is similar to chondroitin sulphate, and recent efforts focused on the development of genetic and fermentation strategies to increase its production titers up to technologically attractive levels. However, the control of the metabolic pathways leading to CPS synthesis together with the effect of varying the concentration of pathway intermediates on CPS final titers, is still quite unexplored, and not fully understood. In the present study four genes involved in the biosynthesis of UDP-sugar CPS precursors, namely kfoA, kfoF, pgm, and galU, were overexpressed in different combinations, and diversely affected the biosynthetic machinery. At the physiological level, results revealed a central role for kfoF, coding for UDP glucose dehydrogenase, that increased CPS production mostly. In the attempt to unravel the molecular mechanisms regulating CPS biosynthesis, an in depth analysis of the proteome of the recombinant strains overexpressing respectively pgm and galU, and pgm, galU, and kfoF was performed and compared to the wild type. Although, interestingly, in both strains the impact of the genetic manipulation seemed rather limited at the proteome level, results obtained from the triple mutant indicated a crosstalk between the two pathways leading to UDP sugar precursors biosynthesis, and also an unexpected link with the purine biosynthetic pathway. Overall our results present new insights into the role of metabolic intermediates for the formation of capsular polysaccharides, utilizing a systematic approach of metabolic engineering, combined with state-of-the-art quantitative proteomic approaches, as well as genetic and physiological information. PMID- 29578573 TI - Hollow microcarriers for large-scale expansion of anchorage-dependent cells in a stirred bioreactor. AB - With recent advances in biotechnology, mammalian cells are used in biopharmaceutical industries to produce valuable protein therapeutics and investigated as effective therapeutic agents to permanently degenerative diseases in cell based therapy. In these exciting and actively expanding fields, a reliable, efficient, and affordable platform to culture mammalian cells on a large scale is one of the most vital necessities. To produce and maintain a very large population of anchorage-dependent cells, a microcarrier-based stirred tank bioreactor is commonly used. In this approach, the cells are exposed to harmful hydrodynamic shear stress in the bioreactor and the mass transfer rates of nutrients and gases in the bioreactor are often kept below an optimal level to prevent cellular damages from the shear stress. In this paper, a hollow microcarrier (HMC) is presented as a novel solution to protect cells from shear stress in stirred bioreactors, while ensuring sufficient and uniform mass transfer rate of gases and nutrients. HMC is a hollow microsphere and cells are cultured on its inner surface to be protected, while openings on the HMC provide sufficient exchange of media inside the HMC. As a proof of concept, we demonstrated the expansion of fibroblasts, NIH/3T3 and the expansion and cardiac differentiation of human induced pluripotent stem cells, along with detailed numerical analysis. We believe that the developed HMC can be a practical solution to enable large-scale expansion of shear-sensitive anchorage-dependent cells in an industrial scale with stirred bioreactors. PMID- 29578574 TI - Time to challenge the spurious hierarchy of systematic over narrative reviews? PMID- 29578575 TI - Hybrid chickadees are deficient in learning and memory. AB - Identifying the phenotypes underlying postzygotic reproductive isolation is crucial for fully understanding the evolution and maintenance of species. One potential postzygotic isolating barrier that has rarely been examined is learning and memory ability in hybrids. Learning and memory are important fitness-related traits, especially in scatter-hoarding species, where accurate retrieval of hoarded food is vital for winter survival. Here, we test the hypothesis that learning and memory ability can act as a postzygotic isolating barrier by comparing these traits among two scatter-hoarding songbird species, black-capped (Poecile atricapillus) and Carolina chickadees (Poecile carolinensis), and their naturally occurring hybrids. In an outdoor aviary setting, we find that hybrid chickadees perform significantly worse on an associative learning spatial task and are worse at solving a novel problem compared to both parental species. Deficiencies in learning and memory abilities could therefore contribute to postzygotic reproductive isolation between chickadee species. Given the importance of learning and memory for fitness, our results suggest that these traits may play an important, but as yet overlooked, role in postzygotic reproductive isolation. PMID- 29578576 TI - Characterization of a membrane-separated and a membrane-less electrobioreactor for bioelectrochemical syntheses. AB - Bioelectrochemical systems (BESs) have the potential to contribute to the energy revolution driven by the new bio-economy. Until recently, simple reactor designs with minimal process analytics have been used. In recent years, assemblies to host electrodes in bioreactors have been developed resulting in so-called "electrobioreactors." Bioreactors are scalable, well-mixed, controlled, and therefore widely used in biotechnology and adding an electrode extends the possibilities to investigate bioelectrochemical production processes in a standard system. In this work, two assemblies enabling a separated and non separated electrochemical operation, respectively, are designed and extensively characterized. Electrochemical losses over the electrolyte and the membrane were comparable to H-cells, the bioelectrochemical standard reaction system. An effect of the electrochemical measurements on pH measurements was observed if the potential is outside the range of -1,000 to +600 mV versus Ag/AgCl. Electrobiotechnological characterization of the two assemblies was done using Shewanella oneidensis as an electroactive model organism. Current production over time was improved by a separation of anodic and cathodic chamber by a Nafion(r) membrane. The developed electrobioreactor was used for a scale-up of the anaerobic bioelectrochemical production of organic acids and lysine from glucose using an engineered Corynebacterium glutamicum. Comparison to a small-scale custom-made electrobioreactor indicates that anodic electro-fermentation of lysine and organic acids might not be limited by the BES setup but by the biocatalysis of the cells. PMID- 29578577 TI - Pharmacokinetics and Tolerability of Letermovir Coadministered With Azole Antifungals (Posaconazole or Voriconazole) in Healthy Subjects. AB - Letermovir is a human cytomegalovirus terminase inhibitor for cytomegalovirus infection prophylaxis in hematopoietic stem cell transplant recipients. Posaconazole (POS), a substrate of glucuronosyltransferase and P-glycoprotein, and voriconazole (VRC), a substrate of CYP2C9/19, are commonly administered to transplant recipients. Because coadministration of these azoles with letermovir is expected, the effect of letermovir on exposure to these antifungals was investigated. Two trials were conducted in healthy female subjects 18 to 55 years of age. In trial 1, single-dose POS 300 mg was administered alone, followed by a 7-day washout; then letermovir 480 mg once daily was given for 14 days with POS 300 mg coadministered on day 14. In trial 2, on day 1 VRC 400 mg was given every 12 hours; on days 2 and 3, VRC 200 mg was given every 12 hours, and on day 4 VRC 200 mg. On days 5 to 8, letermovir 480 mg was given once daily. Days 9 to 12 repeated days 1 to 4 coadministered with letermovir 480 mg once daily. In both trials, blood samples were collected for the assessment of the pharmacokinetic profiles of the antifungals, and safety was assessed. The geometric mean ratios (90%CIs) for POS+letermovir/POS area under the curve and peak concentration were 0.98 (0.83, 1.17) and 1.11 (0.95, 1.29), respectively. Voriconazole+letermovir/VRC area under the curve and peak concentration geometric mean ratios were 0.56 (0.51, 0.62) and 0.61 (0.53, 0.71), respectively. All treatments were generally well tolerated. Letermovir did not affect POS pharmacokinetics to a clinically meaningful extent but decreased VRC exposure. These results suggest that letermovir may be a perpetrator of CYP2C9/19-mediated drug-drug interactions. PMID- 29578578 TI - Confirmatory Population Pharmacokinetic Analysis for Sirukumab, a Human Monoclonal Antibody Targeting Interleukin-6, in Patients With Moderately to Severely Active Rheumatoid Arthritis. AB - The population pharmacokinetics of sirukumab, a human immunoglobulin G1kappa monoclonal antibody against interleukin-6, were characterized in patients with moderately to severely active rheumatoid arthritis in 4 phase 3 studies (SIRROUND D, -T, -H, and -M). A total of 17 034 serum concentrations were analyzed from 1991 rheumatoid arthritis patients who received subcutaneous administration of sirukumab 50 mg every 4 weeks or 100 mg every 2 weeks. A stepwise confirmatory population PK analysis was conducted to accommodate the staged data release and the sparse sampling nature of phase 3 studies and to assess the potential covariate influences in an unbiased and timely manner. The base model, that is, a 1-compartment linear model with first-order absorption and first-order elimination, was prespecified based on prior information from a phase 2 study along with information about phase 3 study design. The covariate model was also prespecified based on pharmacological/physiological relevance and sample size. After the primary covariate analysis, a simplified model was produced by removing covariates with effect sizes <10%. The estimated apparent clearance (CL/F) and volume of distribution were 0.641 L/day and 16.1 L, respectively, at standard body weights of 70 kg. The terminal elimination half-life was approximately 17.4 days. Sirukumab CL/F and volume of distribution increased with body weight, and CL/F was higher in patients with diabetic comorbidity. Simulations suggest that the effects of diabetic comorbidity and weight on sirukumab exposure were additive. To fully understand the clinical relevance including potential dose adjustment, current covariate findings need to be evaluated concurrently with the efficacy and safety data. PMID- 29578579 TI - Intensity modulated operating mode of the rotating gamma system. AB - PURPOSE: The purpose of this work was to explore two novel operation modalities of the rotating gamma systems (RGS) that could expand its clinical application to lesions in close proximity to critical organs at risk (OAR). METHODS: The approach taken in this study consists of two components. First, a Geant4-based Monte Carlo (MC) simulation toolkit is used to model the dosimetric properties of the RGS Vertex 360TM for the normal, intensity modulated radiosurgery (IMRS), and speed modulated radiosurgery (SMRS) operation modalities. Second, the RGS Vertex 360TM at the Rotating Gamma Institute in Debrecen, Hungary is used to collect experimental data for the normal and IMRS operation modes. An ion chamber is used to record measurements of the absolute dose. The dose profiles are measured using Gafchromic EBT3 films positioned within a spherical water equivalent phantom. RESULTS: A strong dosimetric agreement between the measured and simulated dose profiles and penumbra was found for both the normal and IMRS operation modes for all collimator sizes (4, 8, 14, and 18 mm diameter). The simulated falloff and maximum dose regions agree better with the experimental results for the 4 and 8 mm diameter collimators. Although the falloff regions align well in the 14 and 18 mm collimators, the maximum dose regions have a larger difference. For the IMRS operation mode, the simulated and experimental dose distributions are ellipsoidal, where the short axis aligns with the blocked angles. Similarly, the simulated dose distributions for the SMRS operation mode also adopt an ellipsoidal shape, where the short axis aligns with the angles where the orbital speed is highest. For both modalities, the dose distribution is highly constrained with a sharper penumbra along the short axes. CONCLUSIONS: Dose modulation of the RGS can be achieved with the IMRS and SMRS modes. By providing a highly constrained dose distribution with a sharp penumbra, both modes could be clinically applicable for the treatment of lesions in close proximity to critical OARs. PMID- 29578580 TI - MAO-B and COMT Genetic Variations Associated With Levodopa Treatment Response in Patients With Parkinson's Disease. AB - The most commonly used Parkinson's disease (PD) treatment is the replacement of dopamine by its levodopa precursor (l-dopa). Monoamine oxidase-B (MAO-B) and catechol-o-methyl transferase (COMT) are enzymes involved in the metabolism and regulation of dopamine availability. In our study we investigated the possible relation among selected single-nucleotide polymorphisms (SNPs) in the MAO-B (rs1799836) and COMT (rs4680) genes and the therapeutic response to levodopa (l dopa). A total of 162 Brazilian patients from the Pro-Parkinson service of Clinics Hospital of Pernambuco diagnosed with sporadic PD and treated with levodopa were enrolled. PD patients were stratified into 2 groups according to the daily levodopa dose. MAO-B and COMT SNP genotyping was conducted by polymerase chain reaction-restriction fragment length polymorphism. After multivariate analysis, we observed a significant difference between PD groups for the following variables: sex (P = .02), longer duration of disease (P = .02), longer levodopa therapy duration (P = .01), younger onset of PD (P = .01), and use of COMT inhibitor (P = .02). We observed that patients carrying MAO-B (rs1799836) A and AA genotypes and COMT (rs4680) LL genotype suffered more frequently from levodopa-induced-dyskinesia. In addition, we found an increased risk of 2.84-fold for male individuals carrying the MAO-B G allele to be treated with higher doses of levodopa (P = .04). We concluded that before beginning PD pharmacological treatment, it is important to consider the genetic variants of the MAO-B and COMT genes and the sex, reinforcing the evidence that sexual dimorphism in the genes related to dopamine metabolism might affect PD treatment. PMID- 29578581 TI - Truncation of the processive Cel5A of Thermotoga maritima results in soluble expression and several fold increase in activity. AB - Cel5A of Thermotoga maritima, a 37 kDa cellulase of the family GH5, was expressed in partially soluble state in E. coli. However, the truncated version tCel5A1, produced by removing ten residues from the C-terminal of Cel5A, was expressed in a completely soluble form. tCel5A1 showed 7.3- fold increased specific activity against carboxy methyl cellulose while the increase in activities against regenerated amorphous cellulose and Avicel were 21 and 16 fold, respectively. tCel5A1 is stable at 60 degrees C for more than 2 hr and it showed temperature and pH optima 70 degrees C and 6.0, respectively, under the assay conditions used. These characteristics are similar to those of the native enzyme. As expected, CD spectral analysis showed that C-terminal truncation has little effect on the secondary structure of the molecule. tCel5A1 showed higher binding to pretreated rice straw (84%) as compared to the native form (46%). Molecular modelling analysis of tCel5A1 showed that the removal of C-terminal residues exposed the active site residues Glu253, Trp286, and Phe292, which are located in the catalytic cavity close to the C-terminus. Making these residues more accessible to the substrate would result in increased activity. The ratio of 10.01 between the soluble to the insoluble reducing groups produced from RAC on treatment with tCel5A1, and the presence of cellobiose as the major end product in the hydrolysate showed that tCel5A1 is a processive cellulase. Although other processive cellulases belonging to the family GH5, mainly of the fungal origin, have been reported, but tCel5A1, to our knowledge, is the first processive cellulase from an extreme thermophile reported so far. PMID- 29578582 TI - Long-term follow-up of Chagas heart disease patients receiving an implantable cardioverter-defibrillator for secondary prevention. AB - BACKGROUND: Chagas heart disease (CHD) is a dilated cardiomyopathy characterized by malignant ventricular arrhythmias and increased risk of sudden cardiac death (SCD). Much controversy exists concerning the efficacy of implantable cardioverter-defibrillator (ICDs) in CHD because of mixed results observed. We report our long-term experience with ICDs for secondary prevention in CHD, with the specific aim of assessing the results in groups with preserved or depressed global left ventricular function. METHODS: 111 patients (75 males; 60 +/- 12 years) were followed for 1,948 +/- 1,275 days after ICD. Time to death was the primary outcome; LVEF <= 45% the exposure; and age, gender, and ICD therapy delivery the potential confounders. We used time-to-event methods and Cox proportional models for analysis, censoring observations at time of death or at 5 year follow-up in survivors. RESULTS: Seventy-two percent of the patients presented at least one sustained ventricular arrhythmia requiring appropriate therapy, and only three patients received inappropriate therapy. Death occurred in 50 (45%) patients, with an annual mortality rate of 8.4%, mostly due to refractory heart failure or noncardiac causes. Unadjusted survival rates were significantly distinct between patients with left ventricular ejection fraction (LVEF) <= 45% (26 deaths), 50.5% (95% confidence interval [CI]: 36.2%-63.2%) when compared to patients with LVEF > 45% (10 deaths), 77.6% (95% CI: 62.3%-87.3%, P < 0.01). After adjusting for confounders, low LVEF (hazard ratio [HR]: 5.2, 95% CI: 2.3-11.6), age (HR: 1.04, 95% CI: 1.01-1.07), and female gender (HR: 3.97, 95% CI: 1.85-8.54) were independently associated with the outcome. CONCLUSIONS: ICDs successfully aborted life-threatening arrhythmias in CHD patients. Impaired left ventricular function predicted higher mortality in CHD patients with an ICD for secondary prevention of SCD. PMID- 29578584 TI - Rearrangements under confinement lead to increased binding energy of Synaptotagmin-1 with anionic membranes in Mg2+ and Ca2. AB - Synaptotagmin-1 (Syt1) is the primary calcium sensor (Ca2+ ) that mediates neurotransmitter release at the synapse. The tandem C2 domains (C2A and C2B) of Syt1 exhibit functionally critical, Ca2+ -dependent interactions with the plasma membrane. With the surface forces apparatus, we directly measure the binding energy of membrane-anchored Syt1 to an anionic membrane and find that Syt1 binds with ~6 kB T in EGTA, ~10 kB T in Mg2+ and ~18 kB T in Ca2+ . Molecular rearrangements measured during confinement are more prevalent in Ca2+ and Mg2+ and suggest that Syt1 initially binds through C2B, then reorients the C2 domains into the preferred binding configuration. These results provide energetic and mechanistic details of the Syt1 Ca2+ -activation process in synaptic transmission. PMID- 29578583 TI - Multi-Invasion-Induced Rearrangements as a Pathway for Physiological and Pathological Recombination. AB - Cells mitigate the detrimental consequences of DNA damage on genome stability by attempting high fidelity repair. Homologous recombination templates DNA double strand break (DSB) repair on an identical or near identical donor sequence in a process that can in principle access the entire genome. Other physiological processes, such as homolog recognition and pairing during meiosis, also harness the HR machinery using programmed DSBs to physically link homologs and generate crossovers. A consequence of the homology search process by a long nucleoprotein filament is the formation of multi-invasions (MI), a joint molecule in which the damaged ssDNA has invaded more than one donor molecule. Processing of MI joint molecules can compromise the integrity of both donor sites and lead to their rearrangement. Here, two mechanisms for the generation of rearrangements as a pathological consequence of MI processing are detailed and the potential relevance for non-allelic homologous recombination discussed. Finally, it is proposed that MI-induced crossover formation may be a feature of physiological recombination. PMID- 29578585 TI - Clinical Pharmacokinetics of Sulfobutylether-beta-Cyclodextrin in Patients With Varying Degrees of Renal Impairment. AB - Delafloxacin, a fluoroquinolone, has activity against Gram-positive organisms including methicillin-resistant S aureus and fluoroquinolone-susceptible and resistant Gram-negative organisms. The intravenous formulation of delafloxacin contains the excipient sulfobutylether-beta-cyclodextrin (SBECD), which is eliminated by renal filtration. This study examined the pharmacokinetics and safety of SBECD after single intravenous (IV) infusions in subjects with renal impairment. The study was an open-label, parallel-group, crossover study in subjects with normal renal function or mild, moderate, or severe renal impairment, and those with end-stage renal disease undergoing hemodialysis. Subjects received 300 mg delafloxacin IV or placebo IV, containing 2400 mg SBECD, in 2 periods separated by >=14-day washouts. SBECD total clearance decreased with decreasing renal function, with a corresponding increase in area under the concentration-time curve (AUC0-infinity ). After IV delafloxacin 300 mg administration, SBECD mean total clearance was 6.28 and 1.24 L/h, mean AUC0 infinity was 387 and 2130 h.MUg/mL, and mean renal clearance was 5.36 and 1.14 L/h in normal and severe renal subjects, respectively. Similar values were obtained after IV placebo administration. In subjects with end-stage renal disease, delafloxacin 300 mg IV produced mean SBECD AUC0-48 values of 2715 and 7861 h.MUg/mL when dosed before and after hemodialysis, respectively. Total SBECD clearance exhibited linear relationships to estimated glomerular filtration rate and creatinine clearance. Single doses of IV delafloxacin 300 mg and IV placebo were well tolerated in all groups. In conclusion, decreasing renal function causes reduced SBECD clearance and increased exposures, but SBECD continues to exhibit a good safety and tolerability profile in IV formulations. PMID- 29578586 TI - Religion in the Hallways: Academic Performance and Psychological Distress among Immigrant origin Muslim Adolescents in High Schools. AB - Islamic norms and Islamophobia present unique challenges for Muslim adolescents in Western countries. For Muslim students, even "secular" public schools are not a religion-free space because their religious beliefs and values are central in their manner of living. To inquire more about these issues, an exploratory sequential design mixed-method study was conducted that included focus groups and a survey addressing the public school experiences of Muslim adolescents in a Midwestern state in the United States and how those experiences are related to their academic achievement, educational aspirations, and psychological adjustment. Overall, the findings characterize this study's sample as coping well in the school context in terms of academic achievement, high educational expectations, and relatively low levels of psychological distress. However, those who experience greater frequency and severity of hassles at school report higher levels of psychological distress. In particular, the frequency of hassles associated with representing Islam, limited English competency, relations with both Muslim and non-Muslim peers, and religious discrimination at school related to increased distress. Together, these findings suggest the importance of considering both individual and ecological determinants of wellbeing for Muslim adolescents. The findings also suggest the importance of looking more carefully at the sample, context, and time when the data were collected before making generalizations within or across cultural and/or religious groups. PMID- 29578587 TI - Utilizing an ecological framework to integrate social identities and sociopolitical analysis in psychotherapy. AB - This article explores how the political events from the past year have influenced psychotherapeutic sessions with a female adolescent who is Peruvian, undocumented, and initially presented with symptoms of anxiety and a history of trauma. Focusing on this case example and utilizing an ecological framework, this article explores how the social identities of the therapist and their relation to power and privilege impact the therapeutic interventions that were chosen and not chosen. Additionally, there is a review of the benefits of consultation with a colleague of differing social identities and how this form of consultation can influence a clinician's reactions to clients regarding social or political issues, as well as how integrating a sociopolitical analysis is a useful and sometimes necessary addition to the usual work of therapy. PMID- 29578588 TI - Electrophysiological characterization of a mitochondrial inner membrane chloride channel in rat brain. AB - Mitochondria are an essential component of cellular integrity and homeostasis, and their functions and pathological processes are highly dependent on mitochondrial ion channels. Anion channels of the inner mitochondrial membrane have been described by direct patch-clamp electrophysiological methods in mitoplasts prepared in cardiac, liver, and brown adipose tissue, but not in brain. Here, using acutely isolated rat brain mitoplasts, we describe the properties of a large conductance, voltage-gated, pH-sensitive, outwardly rectifying chloride channel with conductances of 98 pS and 129 pS at negative and positive membrane potentials, respectively. While the molecular identity of this chloride conductance is unknown, it is unlikely to be a CLIC channel due to differences in the observed electrophysiological properties. PMID- 29578589 TI - Utilization of oral health services network among children and adolescents with leukemia. AB - AIM: To evaluate the use of the network of oral health services by children and adolescents with leukemia, according to the phase of cancer treatment, type of dental treatment received, and access barriers. METHODS AND RESULTS: An exploratory cross-sectional study carried out in a referral hospital in cancer in northeast of Brazil, with all children and adolescents (3-16 years old) with leukemia who used dental services and who attended the medical consultation in the outpatient clinic between March and August 2016. The analysis of the medical records and a structured interview with caregivers were performed. The majority who used only the specialized network were in a single phase of cancer treatment (49.1%), had oral mucositis treatment (79.2%), and had a time of displacement for oral health services greater than 40 minutes (92.6%). In addition, dental care was centered in the specialized network (76.8%) and during hospitalization (37.7%). CONCLUSIONS: The findings suggest that the oral health care of these individuals is centered on tertiary care, reflecting a deficiency in communication between the network services, as well as the nonrecognition of the basic network as a caregiver source by its users. Despite this, more research is needed. PMID- 29578590 TI - Analysis of metabolic networks of Streptomyces leeuwenhoekii C34 by means of a genome scale model: Prediction of modifications that enhance the production of specialized metabolites. AB - The first genome scale model (GSM) for Streptomyces leeuwenhoekii C34 was developed to study the biosynthesis pathways of specialized metabolites and to find metabolic engineering targets for enhancing their production. The model, iVR1007, consists of 1,722 reactions, 1,463 metabolites, and 1,007 genes, it includes the biosynthesis pathways of chaxamycins, chaxalactins, desferrioxamines, ectoine, and other specialized metabolites. iVR1007 was validated using experimental information of growth on 166 different sources of carbon, nitrogen and phosphorous, showing an 83.7% accuracy. The model was used to predict metabolic engineering targets for enhancing the biosynthesis of chaxamycins and chaxalactins. Gene knockouts, such as sle03600 (L-homoserine O acetyltransferase), and sle39090 (trehalose-phosphate synthase), that enhance the production of the specialized metabolites by increasing the pool of precursors were identified. Using the algorithm of flux scanning based on enforced objective flux (FSEOF) implemented in python, 35 and 25 over-expression targets for increasing the production of chaxamycin A and chaxalactin A, respectively, that were not directly associated with their biosynthesis routes were identified. Nineteen over-expression targets that were common to the two specialized metabolites studied, like the over-expression of the acetyl carboxylase complex (sle47660 (accA) and any of the following genes: sle44630 (accA_1) or sle39830 (accA_2) or sle27560 (bccA) or sle59710) were identified. The predicted knockouts and over-expression targets will be used to perform metabolic engineering of S. leeuwenhoekii C34 and obtain overproducer strains.

AB - BACKGROUND: Cancer is the leading cause of death for Asian Americans. The authors evaluated the status of cancer prevention for Chinese Americans in San Francisco, which has had years of cancer prevention efforts. METHODS: Through a community based clinic serving Chinese Americans, a randomized, controlled trial (n = 395) was conducted among participants who attended either a cancer prevention seminar or biospecimen education seminar. Changes in knowledge, attitudes, and screening completion/intent were measured across and between seminar groups. RESULTS: Participants were mostly women who had low acculturation and education levels. Over two-thirds to almost all participants knew about modifiable risk factors for cancer and that screening tests were available, including for lung cancer. The majority of women had already completed mammography and Papanicolaou (Pap) tests. Approximately one-half reported having completed colorectal cancer screening, prostate screening, or hepatitis B screening. Most were nonsmokers, but about one half "strongly agreed" that they would want a test for tobacco smoke exposure. After the cancer prevention seminar, significant increases within group were noted for knowledge (eating healthy foods, from 93.1% to 97.7% [P = .0002]; secondhand smoke causes cancer, from 66.3% to 74.8% [P = .04]) and for screening completion/intent (colorectal cancer, from 58.1% to 64.5% [P = .002] cervical cancer, from 72.9% to 75.5% [P = .04]) and there was a trend toward an increase for prostate cancer (from 50.0% to 61.1%; P = .10). There was a significant change between groups for eating healthy foods (P = .004). CONCLUSIONS: The current reports documents the gains in cancer prevention among Cantonese-speaking Chinese Americans, fostered by academic, community, and public health efforts. A community-based seminar demonstrated improvement in some cancer knowledge or screening intent and opportunities for continued efforts. Cancer 2018;124:1622 30. (c) 2018 American Cancer Society. PMID- 29578591 TI - Inhibitory effects of Danhong Injection and its major constituents on human cytochrome P450 enzymes in vitro. AB - Danhong Injection (DHI) as a Chinese patent medicine is mainly used to treat ischemic encephalopathy and coronary heart disease in combination with other chemotherapy. However, the information on DHI's potential drug interactions is limited. The goal of this work was to examine the potential P450-mediated metabolism drug interaction arising from DHI and its active components. The results showed that DHI inhibited CYP2C19, CYP2D6, CYP3A4, CYP2E1 and CYP2C9 with IC50 values of 1.26, 1.42, 1.63, 1.10 and 1.67% (v/v), respectively. Danshensu and rosmarinic acid inhibited CYP2E1 and CYP2C9 with IC50 values of 36.63 and 75.76 MUm, and 34.42 and 76.89 MUm, respectively. Salvianolic acid A and B inhibited CYP2D6, CYP2E1 and CYP2C9 with IC50 values of 33.79, 21.64 and 31.94 MUm, and 45.47, 13.52 and 24.15 MUm, respectively. The study provides some useful information for safe and effective use of DHI in clinical practice. PMID- 29578593 TI - High frequency of the PNPLA3 rs738409 [G] single-nucleotide polymorphism in Hmong individuals as a potential basis for a predisposition to chronic liver disease. AB - BACKGROUND: An exploratory study was performed to determine the prevalence of the patatin-like phospholipase domain-containing protein 3 (PNPLA3) rs78409 [G] allele among the Hmong as a risk factor for nonalcoholic fatty liver disease (NAFLD). NAFLD/nonalcoholic steatohepatitis is the world's most common chronic liver disease and is expected to replace viral hepatitis as the leading cause of cirrhosis and potential precursor to hepatocellular carcinoma (HCC). Of all populations in California, the Hmong experience the highest risk of death from HCC and the highest prevalence of metabolic syndrome risk factors among Asians that predispose them to NAFLD. Here a genetic explanation was sought for the high rates of chronic liver disease among the Hmong. The literature pointed to the PNPLA3 rs738409 [G] allele as a potential genetic culprit. METHODS: Cell-free DNA was isolated from 26 serum samples previously collected in community settings. Quantitative polymerase chain reaction-based single-nucleotide polymorphism (SNP) genotyping was performed with a validated TaqMan SNP genotyping assay, and results were analyzed with TaqMan Genotyper software. RESULTS: The PNPLA3 rs738409 [C>G] variant occurred at a frequency of 0.46 (12 of 26; 95% confidence interval, 0.27-0.67). This carrier rate would rank the Hmong as the third highest population in the 1000 Genomes Project. CONCLUSIONS: Although this small sample size limits the generalizability, the high frequency rates of this allele along with the presence of metabolic syndrome risk factors warrant further studies into the etiology of NAFLD among the Hmong.

AB - BACKGROUND: Among Chinese American individuals, only approximately 42% of cases of colorectal cancer (CRC) are diagnosed at an early stage, possibly because these patients are less likely than non-Hispanic white individuals to undergo CRC screening. METHODS: Primary care physicians (PCPs) were recruited from a local independent practice association serving Chinese Americans and randomized into early-intervention and delayed-intervention groups. PCPs in the early intervention group received continuing medical education (CME), and their patients received an intervention mailer, consisting of a letter with the PCP's recommendation, a bilingual educational booklet, and a fecal occult blood test (FOBT) kit in year 1. PCPs in the delayed-intervention group received no CME, and their patients received the mailers in year 2. RESULTS: A total of 20 PCPs were assigned to the early-intervention and 22 PCPs to the delayed-intervention group. A total of 3120 patients of these participating PCPs who had undergone CRC screening that was due during the study period were included. A total of 915 mailers were sent in year 1 and 830 mailers were sent in year 2. FOBT screening rates increased from 26.7% at baseline to 58.5% in year 1 in the early intervention group versus 19.6% at baseline to 22.2% in year 1 in the delayed intervention group (P<.0001). The overall effect size of the mailer intervention with or without CME was estimated as a difference of 26.6 percentage points (95% confidence interval, 22.0-31.2 percentage points) from baseline compared with usual care. The intervention was found to have no impact on rates of colonoscopy or sigmoidoscopy. CONCLUSIONS: The results of the current pilot study demonstrated that a mailer including educational materials and FOBT kits can increase CRC screening rates with or without CME for the PCPs.

PMID- 29578595 TI - Impact of a smoke-free-living educational intervention for smokers and household nonsmokers: A randomized trial of Chinese American pairs. AB - BACKGROUND: Chinese American men smoke at a high rate, which puts household nonsmokers at risk. The objective of this study was to evaluate the effectiveness of a brief-intensity versus moderate-intensity smoke-free-living educational intervention for household pairs. METHODS: The authors conducted a randomized controlled trial of Cantonese-speaking Chinese American smoker and household nonsmoker pairs in San Francisco, California. Pairs were randomized to moderate intensity or brief-intensity group sessions with their household partner. The moderate-intensity group received 2 group sessions, a laboratory report of their baseline smoke exposure, as measured by 4-(methylnitrosamino)-1-(3-pyridyl)-1 butanol (NNAL), and 3 follow-up calls over 6 months. The brief-intensity group received 1 group session on tobacco-cessation resources. Primary outcomes were biochemically validated, past-month smoking abstinence and elimination of nonsmoker household exposure at 12 months. RESULTS: Participant pairs (n = 203) were male smokers, one-half of whom did not intend to quit within 6 months, with mostly female spouses as household nonsmokers. Approximately three-quarters of nonsmokers in both groups already had smoke-free home rules. At 12 months, smokers in both groups had similar biochemically validated 30-day abstinence rates (moderate-intensity group, 0%-20.7%; brief-intensity group, 0%-20.0%; P = .002 over time). More smokers in the moderate-intensity group used subsequent cessation group classes (moderate-intensity group, 50%; brief-intensity group, 24%; P = .004). Household nonsmokers in both groups had similar biochemically validated rates of no home exposure (moderate-intensity group, 24.5%-42.2%; brief intensity group, 24.8%-33.3%; P = .0001 over time). CONCLUSIONS: A moderate intensity smoke-free-living educational intervention for Chinese-speaking household pairs was not more effective than a brief-intensity intervention for smoking abstinence and elimination of household nonsmoker exposure. Abstinence rates were similar to those achieved with standard group counseling. Cancer 2018;124:1590-8. (c) 2018 American Cancer Society. PMID- 29578596 TI - Social-cultural, traditional beliefs, and health system barriers of hepatitis B screening among Hmong Americans: A case study. AB - BACKGROUND: The incidence of liver cancer in Hmong Americans is 5 times higher than that of non-Hispanic whites, and there is a low hepatitis B screening rate (24%) among Hmong adults compared with other Asian American populations. The purpose of this study was to examine the Hmong's perceptions on social-cultural determinants, traditional health beliefs, and health care system barriers that influenced community-based hepatitis B screening interventions. METHODS: A qualitative method was used, integrating a collective case study research design. In-depth interviews were used to collect data from 20 Hmong adults from the greater Sacramento area. A pattern matching analytic technique was used to analyze the data. The main core elements of Culture Care Theory were used to capture the key themes presented by the participants. RESULTS: Protecting a family's reputation; fear of doctors, medical procedures, and test results; lack of trust in medical doctors and medical care services; and using Hmong herbal medicines and practicing spiritual healing were identified as social-cultural and traditional health belief barriers to obtaining HBV screening. Health care costs, perceived discrimination, lack of transportation, linguistic discordance, and poor quality of care were identified as barriers to accessing high-quality health care services and obtaining hepatitis B screening. CONCLUSION: Providers, health policy makers, researchers, and community-based organizations will need to work together to develop intervention strategies to address the social-cultural factors, traditional health beliefs, and health care challenges that influence obtaining hepatitis B screening in the Hmong community.

PMID- 29578597 TI - Perspectives of Chinese American smoker and nonsmoker household pairs about the creating smokefree living together program. AB - BACKGROUND: Chinese men smoke at high rates, and this puts household members at risk for tobacco-related diseases. Culturally responsive interventions that provide education and support are needed to promote smokefree living and reduce smoke exposure, particularly for US immigrants who experience changes in smokefree social norms. This qualitative study examines perspectives of Chinese American smoker and nonsmoker household pairs in the Creating Smokefree Living Together program. METHODS: Four focus groups were conducted with 30 Chinese American participants (15 smokers and 15 nonsmokers) who, in household pairs, completed smokefree education interventions of either brief or moderate intensity. Nearly three-quarters of the smokers continued to smoke after the intervention at the time of focus group participation. All smokers were male, and most household nonsmokers were female spouses. All participants had limited English proficiency. Focus group meetings were recorded, and the recordings were translated and transcribed. Transcripts and field notes were thematically analyzed. RESULTS: The following themes, shared by smokers and nonsmokers across interventions, were identified: 1) there was a preference for dyadic and group interventions because of the support offered, 2) increased knowledge of the health harms of smoke exposure within a pair improved the nonsmoker's support for smokefree living, 3) learning communication strategies improved household relationships and assertiveness for smokefree environments, 4) biochemical feedback was useful but had short-term effects, and 5) project magnets provided cues to action. CONCLUSIONS: Involving household partners is critical to smokefree interventions. Simple reminders at home appear to be more powerful than personal biochemical feedback of smoke exposure for sustaining motivation and engagement in ongoing behavioral changes within the household.

PMID- 29578598 TI - The Asian American Network for Cancer Awareness, Research, and Training (AANCART)'s contributions toward reducing Asian American cancer health disparities, 2000-2017. AB - BACKGROUND: In 2000 and in 2 subsequent 5-year cycles, the National Cancer Institute funded grantees on a regional and national basis to address community needs for cancer awareness, research, and training. The Asian American Network for Cancer Awareness, Research and Training (AANCART) is fortunate to have been funded since 2000 to focus on mitigating cancer health disparities facing Asian Americans residing primarily in California and Hawaii. This article highlights AANCART's achievements with respect to the original specific aims and unanticipated outcomes in its most recent funded cycle. METHODS: Sources included reports to the National Cancer Institute and peer-reviewed articles as well as the insights of the 3 principal investigators. RESULTS: All aims of the original application (infrastructure, outreach, research, and training) were attained or exceeded. Most distinctive was the completion and publication of 8 randomized controlled trials to address Asian American cancer health disparities and its nurture of 14 new and early stage investigators who have been productive in terms of research career trajectories. CONCLUSIONS: AANCART is contributing to mitigating Asian American cancer health disparities by catalyzing academic and community collaborations that have resulted in linguistically specific and culturally tailored educational products, scientifically rigorous interventions addressed at cancer risk factors, and nurturing new and early stage Asian American cancer investigators.

PMID- 29578599 TI - Moving toward a true depiction of tobacco behavior among Asian Indians in California: Prevalence and factors associated with cultural smokeless tobacco product use. AB - BACKGROUND: Asian Indians (AIs) in the United States exhibit disproportionate burdens of oral cancer and cardiovascular disease, which are potentially linked to smokeless tobacco. However, little is known about the use of cultural smokeless tobacco (CST) products in this population. METHODS: California Asian Indian Tobacco Use Survey data from 2004 (n = 1618) were used to investigate CST prevalence among California's AIs. CST products included paan, paan masala, and gutka. A multivariable logistic regression was conducted to examine factors (socioeconomic status, acculturation measures, and religious affiliation) associated with current CST use versus never use. RESULTS: The current CST prevalence was 13.0% (14.0% for men and 11.8% for women). In contrast, the prevalence of current cigarette use was 5.5% (8.7% for men and 1.9% for women), and the prevalence was lower for cultural smoked tobacco (0.1% for bidis and 0.5% for hookahs). Factors associated with CST use included the following: being male, being 50 years old or older, being an immigrant, speaking an AI language at home, having a higher level of education (adjusted odds ratio [AOR] for high school/some college, 2.6; 95% confidence interval [CI], 1.1-6.5; AOR for college degree or higher, 4.0; 95% CI, 1.7-9.5), having a higher income (AOR for $75,000 $100,000, 2.5; 95% CI, 1.3-4.7; AOR for >=$100,000, 2.6; 95% CI, 1.4-5.0), identifying as non-Sikh (AOR for Hinduism, 10.0; 95% CI, 6.0-16.5; AOR for other faiths, 10.2; 95% CI, 5.9-17.7), and disagreeing that spiritual beliefs are the foundation of life (AOR, 2.1; 95% CI, 1.2-3.5). CONCLUSIONS: The current CST prevalence is relatively high among California's AIs in comparison with the prevalence of smoking, with narrower differences between sexes. The association with a higher socioeconomic status is contrary to typical cigarette smoking patterns. Acculturation and religious affiliation are important factors associated with current use. Health care providers and policymakers should consider such determinants for targeted interventions. Cancer 2018;124:1607-13. (c) 2018 American Cancer Society. PMID- 29578600 TI - Colorectal cancer beliefs, knowledge, and screening among Filipino, Hmong, and Korean Americans. AB - BACKGROUND: To the authors' knowledge, there are few studies to date regarding colorectal cancer (CRC) beliefs, knowledge, and screening among multiple Asian American populations, who are reported to have lower CRC screening rates compared with white individuals. The current study was performed to assess knowledge and beliefs regarding the causes of CRC, its prevention, and factors associated with CRC screening among 3 Asian American groups. METHODS: The authors conducted an in language survey with Filipino (Honolulu, Hawaii), Hmong (Sacramento, California), and Korean (Los Angeles, California) Americans aged 50 to 75 years who were sampled through social networks. Bivariate and multivariable analyses were conducted to assess factors associated with CRC screening. RESULTS: The sample of 981 participants was 78.3% female and 73.8% reported limited proficiency in English. Few of the participants were aware that age (17.7%) or family history (36.3%) were risk factors for CRC; 6.2% believed fate caused CRC. Only 46.4% of participants knew that screening prevented CRC (74.3% of Filipino, 10.6% of Hmong, and 55.8% of Korean participants; P<.001). Approximately two-thirds of participants reported ever having undergone CRC screening (76.0% of Filipino, 72.0% of Hmong, and 51.4% of Korean participants; P<.001) and 48.6% were up to date for screening (62.2% of Filipino, 43.8% of Hmong, and 41.4% of Korean participants; P<.001). Factors found to be significantly associated with ever screening were being Korean (compared with Filipino), having a family history of CRC, having health insurance or a regular source of health care, and knowing that a fatty diet caused CRC. Believing that fate caused CRC and that praying prevented it were found to be negatively associated with ever screening. Factors associated with being up to date for CRC screening included being born in the United States, having a family history of CRC, and having access to health care. CONCLUSIONS: Knowledge regarding the causes of CRC and its prevention among Filipino, Hmong, and Korean individuals is low. However, health care access, not knowledge or beliefs, was found to be a key determinant of CRC screening. Cancer 2018;124:1552-9. (c) 2018 American Cancer Society. PMID- 29578601 TI - Time, trust, and transparency: Lessons learned from collecting blood biospecimens for cancer research from the Asian American community. AB - BACKGROUND: Biospecimens from racially diverse groups are needed to advance cancer research. The Asian American Cancer Education Study was developed to increase the number and proportion of blood biospecimen donations from Asian Americans for cancer research. METHODS: The authors' targeted approach included 2 types of community engagement, in-reach (within institution to Asian American patients with cancer) and outreach (external to institution to the general Asian American community). Participants received in-language biospecimen education followed by the opportunity to donate blood biospecimens. Outreach participants donated through our community biospecimen blood drives, and in-reach participants consented to donating an extra tube of blood during their routine blood draws as a patient. Donated blood biospecimens were spun down to serum and plasma to be stored in a biorepository or were sent to the laboratory to test for cancer related risk factors. RESULTS: Three hundred eighty-eight Asian Americans donated 1127 blood biospecimens for cancer research. Four hundred twenty tubes of plasma and serum are currently being stored at the cancer center's biorepository, 39 tubes have been used for cancer genomic research, and 668 tubes were used to characterize cancer-related risk factors. CONCLUSIONS: Building upon the past decade of the National Cancer Institute-funded Asian American Network for Cancer Awareness, Research, and Training's foundation of trust and service among Asian Americans, researchers were able to leverage relationships not only to introduce the idea of biospecimen contribution to the community but to also exceed expectations with regard to the quantity of blood biospecimens collected from Asian Americans.

PMID- 29578602 TI - Colorectal cancer screening prevalence and predictors among Asian American subgroups using Medical Expenditure Panel Survey National Data. AB - BACKGROUND: Asian American (AA) ethnic subgroups are diverse in socio-economic status, years in the United States, English proficiency, and cultures with different health seeking behaviors and health care access. Fifty-two percent of AAs age >=50 years had colorectal cancer screening (CRCS) in 2013, compared with 61% of non-Hispanic whites. We hypothesized that CRCS prevalence among AA ethnicities is heterogeneous and that the reasons related to CRCS among AA subgroups are associated with demographic characteristics, acculturation, health care access, and health attitudes. METHODS: Medical Expenditure Panel Survey data for 2009-2014 compared CRCS status among whites (n = 28,834), Asian Indians (n = 466), Chinese (n = 652), and Filipinos (n = 788). Multivariate logistic regression examined ethnic differences and correlates of CRCS accounting for complex sampling design. RESULTS: Whites had the highest prevalence of screening (62.3%), followed by Filipinos (55.0%), Chinese (50.9%), and Asian Indians (48.6%). Older age, having health insurance, and having a usual care provider predicted CRCS across all ethnicities. Different demographic, health care access, and health attitude predictors within each ethnic group were related to CRCS. CONCLUSION: This study contributes to the literature on influences of differential CRCS prevalence among AA subgroups. CRCS promotion should be tailored according to attitudes and structural barriers affecting screening behavior of specific ethnic subgroups to truly serve the health needs of the diverse AA population.

PMID- 29578603 TI - Results of a lay health education intervention to increase colorectal cancer screening among Filipino Americans: A cluster randomized controlled trial. AB - BACKGROUND: Filipino colorectal cancer (CRC) screening rates fall below Healthy People 2020 goals. In this study, the authors explore whether a lay health educator (LHE) approach can increase CRC screening among Filipino Americans ages 50 to 75 years in Hawai'i. METHODS: A cluster randomized controlled trial from 2012 through 2015 compared an intervention, which consisted of LHEs delivering 2 education sessions and 2 telephone follow-up calls on CRC screening plus a CRC brochure versus an attention control, in which 2 lectures and 2 follow-up calls on nutrition and physical activity plus a CRC brochure were provided. The primary outcome was change in self-reported ever receipt of CRC screening at 6 months. RESULTS: Among 304 participants (77% women, 86% had > 10 years of residence in the United States), the proportion of participants who reported ever having received CRC screening increased significantly in the intervention group (from 80% to 89%; P = .0003), but not in the control group (from 73% to 74%; P = .60). After covariate adjustment, there was a significant intervention effect (odds ratio, 1.9; 95% confidence interval, 1.0-3.5). There was no intervention effect on up-to-date screening. CONCLUSIONS: This first randomized controlled trial for CRC screening among Hawai'i's Filipinos used an LHE intervention with mixed, but promising, results. Cancer 2018;124:1535-42.

AB - BACKGROUND: Nonadherence to colorectal cancer (CRC) screening among Asian Americans is high but not well understood. This study examined correlates of screening intention among Filipino, Hmong, and Korean Americans who were nonadherent to CRC screening. METHODS: Using cross-sectional, preintervention survey data from 504 Asian Americans (115 Filipinos, 185 Hmong, and 204 Koreans) aged 50-75 years who were enrolled in a multisite cluster randomized controlled trial of lay health educator intervention, we analyzed correlates of self reported CRC screening nonadherence, which was defined as not being up-to-date for fecal occult blood test, sigmoidoscopy, or colonoscopy. RESULTS: Only 26.8% of participants indicated intention to obtain screening within 6 months (Hmong: 12.4%; Korean: 30.8%; and Filipino: 42.6%; P < .001). Only one third of participants had undergone a prior screening, and a majority did not know that screening is a method of CRC prevention method (61.3%) or had any knowledge of CRC screening guidelines (53.4%). Multivariable analyses revealed that patient provider ethnicity concordance, provider's recommendation of screening, participants' prior CRC screening, perceived severity and susceptibility of CRC, and knowledge of guidelines were positively associated with screening intention. Specifically, knowing one or more screening guidelines doubled the odds of screening intention (adjusted odds ratio, 2.38; 95% confidence interval, 1.32 4.28). Hmong were less likely to have screening intention than Filipinos, which was unexplained by socio-demographics, health care factors, perceived needs for CRC screening, or knowledge of screening guidelines. CONCLUSION: CRC screening intention among nonadherent Filipino, Hmong, and Korean Americans was low. Targeting knowledge of CRC screening guidelines may be effective strategies for increasing CRC screening intention among nonadherent Asian Americans. Cancer 2018;124:1560-7.

AB - PURPOSE: Investigating factors that can predict medication adherence and quality of life, as well as the influence of adherence to medication on the quality of life among patients with schizophrenia. DESIGN AND METHODS: This study applies descriptive cross-sectional design. Participants were determined from outpatient clinic in a psychiatric hospital in Indonesia. Several questionnaires were used, including self-report, Glasgow Antipsychotics Side-effect Scale, drug attitude inventory and SQOL-18. FINDINGS: Side-effect factor (p < .05) could influence medication adherence. Residential area (p < .05) could significantly influence quality of life. There was also a correlation between medication adherence and quality of life (p < .05). PRACTICE IMPLICATIONS: Findings suggest to put more emphasis on assessing medication side effects. PMID- 29578606 TI - Structural and enzymatic analyses of Anabaena heterocyst-specific alkaline invertase InvB. AB - Anabaena sp. PCC 7120 encodes two alkaline/neutral invertases, namely InvA and InvB. Following our recently reported InvA structure, here we report the crystal structure of the heterocyst-specific InvB. Despite sharing an overall structure similar to InvA, InvB possesses a much higher catalytic activity. Structural comparisons of the catalytic pockets reveal that Arg430 of InvB adopts a different conformation, which may facilitate the deprotonation of the catalytic residue Glu415. We propose that the higher activity may be responsible for the vital role of InvB in heterocyst development and nitrogen fixation. Furthermore, phylogenetic analysis combined with activity assays also suggests the role of this highly conserved arginine in plants and cyanobacteria, as well as some proteobacteria living in highly extreme environments. PMID- 29578607 TI - Mr. Trump: How I learned to stop worrying and love the patient-aggressor. AB - This paper offers an integration of social issues, psychoanalytic theory, and analytic experience in the treatment of a patient whose political values and identifications differed significantly from my own. Our political leanings facilitated a dynamic tension of difference, power, and aggression that mirrored how each of us felt in relation to the current social-political milieu. In particular, the sadomasochistic dynamics on display in the treatment offered me a unique way of understanding my relationship with my patient and opened new ways of understanding the political present. In the end, I learned to stop worrying about getting rid of anger, aggression, and splitting, and instead to embrace what these feelings and behaviors can tell me as a therapist, and what they can inform for my patients about the nature of relationality, identity, and difference. PMID- 29578608 TI - Optimization of bioprocess productivity based on metabolic-genetic network models with bilevel dynamic programming. AB - One of the main goals of metabolic engineering is to obtain high levels of a microbial product through genetic modifications. To improve the productivity of such a process, the dynamic implementation of metabolic engineering strategies has been proven to be more beneficial compared to static genetic manipulations in which the gene expression is not controlled over time, by resolving the trade-off between growth and production. In this work, a bilevel optimization framework based on constraint-based models is applied to identify an optimal strategy for dynamic genetic and process level manipulations to increase productivity. The dynamic enzyme-cost flux balance analysis (deFBA) as underlying metabolic network model captures the network dynamics and enables the analysis of temporal regulation in the metabolic-genetic network. We apply our computational framework to maximize ethanol productivity in a batch process with Escherichia coli. The results highlight the importance of integrating the genetic level and enzyme production and degradation processes for obtaining optimal dynamic gene and process manipulations.

AB - This study was conducted to investigate the extent of absorption in different regions of the gastrointestinal (GI) tract. The relative bioavailability of an apixaban crushed tablet was also assessed to investigate the effect of dissolution on absorption. This was an open-label, randomized, 4-period, 4 treatment crossover study with a 7-day washout period balanced for first-order residual effects in 12 healthy subjects. Subjects received a single dose of a 2.5 mg apixaban solution administered orally, released in the distal small intestine and in the ascending colon. In addition, subjects received a single dose of a 2.5 mg apixaban crushed tablet released in the ascending colon. The solution and crushed tablet were delivered via Enterion capsules. The location of Enterion capsules was monitored using scintigraphic imaging. Apixaban maximum observed plasma concentration (Cmax ) and area under the plasma concentration-time curve from zero to the time of the last quantifiable concentration (AUC0-t ) decreased by approximately 60% when it was delivered to the distal small bowel compared with the oral administration. A greater decrease was observed when it was delivered to the ascending colon, with reductions of 90% and 84% in Cmax and AUC0 t , respectively. A crushed tablet delivered to the ascending colon resulted in exposure that was approximately 40% of that observed for solution released in the same region. These findings indicate that apixaban exhibits region-dependent absorption and that dissolution/solubility of the solid-dose form is limited in the ascending colon. Apixaban absorption decreased progressively along the GI tract, indicating that absorption occurs primarily in the upper GI tract.

Antipsychotic medications are the primary treatment for these disorders. Antipsychotic medications are associated with a variety of adverse effects including tardive dyskinesia. Dyskinesia is a disfiguring movement disorder of the orofacial region that can be tardive (having a slow or belated onset). Tardive dyskinesia is difficult to treat, despite experimentation with several treatments. Calcium channel blockers (diltiazem, nifedipine, nimodipine, verapamil, flunarizine) have been among these experimental treatments. OBJECTIVES: To determine the effects of calcium channel blocker drugs (diltiazem, nifedipine, nimodipine, verapamil) for treatment of neuroleptic-induced tardive dyskinesia in people with schizophrenia, schizoaffective disorder or other chronic mental illnesses. SEARCH METHODS: We searched the Cochrane Schizophrenia Group Trials Register (July 2015 and April 2017), inspected references of all identified studies for further trials and contacted authors of trials for additional information. SELECTION CRITERIA: We selected randomised controlled trials comparing calcium channel blockers with placebo, no intervention or any other intervention for people with both tardive dyskinesia and schizophrenia or serious mental illness who remained on their antipsychotic medication. DATA COLLECTION AND ANALYSIS: We independently extracted data and estimated risk ratios of dichotomous data or mean differences (MD) of continuous data, with 95% confidence intervals (CI). We assumed that people who left the trials early had no improvement. We also created a 'Summary of findings' table using GRADE. MAIN RESULTS: Previous versions of this review included no trials. From the 2015 search, we identified three cross-over trials that could be included. The 2017 search found no new studies relevant to this review. The included trials randomised 47 inpatients with chronic mental illnesses in the USA and China. Trials were published in the 1990s and were of short duration (six to 10 weeks). Overall, the risk of bias was unclear, mainly due to poor reporting; allocation concealment was not described, generation of the sequence was not explicit, studies were not clearly blinded, and attrition and outcome data were not fully reported. Findings were sparse, no study reported on the primary outcome 'no clinically important improvement in tardive dyskinesia symptoms,' but two small studies (37 participants) found no difference on the tardive dyskinesia symptoms scale Abnormal Involuntary Movement Scale (AIMS) scores between diltiazem or flunarizine and placebo after three to four weeks' treatment (MD -0.71, 95% CI 2.68 to 1.26, very low quality evidence). Only one study randomising 20 participants reported on adverse events, and reported that there were no adverse events with flunarizine or with placebo (very low quality evidence). One study with 18 participants reported no events of deterioration in mental state with diltiazem or with placebo (very low quality evidence). No studies reported on acceptability of treatment or on social confidence, social inclusion, social networks or personalised quality of life outcomes designated important to patients. AUTHORS' CONCLUSIONS: Available evidence from randomised controlled trials is extremely limited and very low quality, conclusions cannot be drawn. The effects of calcium channel blockers for antipsychotic-induced tardive dyskinesia are unknown. Their use is experimental and should only be given in the context of well-designed randomised trials.

AB - This paper proposes an ecological view to investigate how disparities in mobile technology use reflect vulnerabilities in communities vis-a-vis disaster preparedness. Data (n=1,603) were collected through a multi-country survey conducted equally in rural and urban areas of Indonesia, Myanmar, Philippines, and Vietnam, where mobile technology has become a dominant and ubiquitous communication and information medium. The findings show that smartphone users' routinised use of mobile technology and their risk perception are significantly associated with disaster preparedness behaviour indirectly through disaster related information sharing. In addition to disaster-specific social support, smartphone users' disaster-related information repertoires are another strong influencing factor. In contrast, non-smartphone users are likely to rely solely on receipt of disaster-specific social support as the motivator of disaster preparedness. The results also reveal demographic and rural-urban differences in disaster information behaviour and preparedness. Given the increasing shift from basic mobile phone models to smartphones, the theoretical and policy-oriented implications of digital disparities and vulnerability are discussed.

AB - Supramolecular systems that respond to the hydrolysis of adenosine phosphates (APs) are attractive for biosensing and to fabricate bioinspired self-assembled materials. Here, we report on the formation of supramolecular complexes between an achiral guanidinium derivative bearing two pyrene moieties, with each of the three adenosine phosphates: AMP, ADP, and ATP. By combining results from circular dichroism spectroscopy and molecular modeling simulations, we explore the induced chirality, the dynamics of the complexes, and the interactions at play, which altogether provide insights into the supramolecular self-assembly between APs and the guanidinium-bispyrene. Finally, we identify the chiroptical signals of interest in mixtures of the guanidinium derivative with the three APs in different proportions. This study constitutes a basis to evolve toward a chiroptical detection of the hydrolysis of APs based on organic supramolecular probes.

AB - A detailed study of diastereomeric complexes of chiral ureido-1,1'-binaphthalene derivatives with chiral 1-phenylethanol showed that a derivative bearing only one urea unit makes five times more stable complex with (S)-enantiomer than with (R) enantiomer of the alcohol. This phenomenon could be used in chiral discrimination processes. The influence of individual parts of the structure on the complexation properties is shown. The probable structure of diastereomeric complexes based on experimental results and computational methods is proposed.

AB - Depression is a common psychiatric disorder with heavy economic and social burdens. Searching new agents with better antidepressant-like activities is of great significance for depression therapy. Tauroursodeoxycholic acid (TUDCA), a clinical drug for gallstone treatment, possesses neuroprotective effects in different brain disorders. However, whether it affects depression remains unclear. We addressed this issue by evaluating the effect of TUDCA on depression induced by chronic unpredictable stress (CUS). Results showed that TUDCA treatment at 200 but not 100 mg/kg prevented the 5 weeks of CUS-induced increases in the immobile time of C57BL6/J mice in the experiments of forced swimming test and tail suspension test as well as the CUS-induced decrease in sucrose intake and crossing numbers in the open-field test, and did not enhance the antidepressant-like effect of fluoxetine. Attenuation of neuroinflammation may be involved in the antidepressant-like effect of TUDCA, as TUDCA treatment (200 mg/kg) normalized the levels of tumor necrosis factor-alpha and interleukin-6 in both hippocampus and prefrontal cortex. The increases in inflammasome and microglial activation markers, including interleukin-beta, nod-like receptor protein 3, and Iba-1, in CUS-treated mice were reduced by TUDCA treatment (200 mg/kg). TUDCA treatment (200 mg/kg) also normalized the changes in markers reflecting the oxidative-nitrosative and endoplasmic reticulum (ER) stress induced by CUS, such as nitric oxide, reduced glutathione, malondialdehyde, glucose-regulated protein 78, and C/EBP homologous protein. These results revealed that TUDCA improved the CUS-induced depression-like behaviors likely through attenuation of neuroinflammation, oxido-nitrosative, and ER stress. PMID- 29578617 TI - Dative and Electron-Sharing Bonding in C2 F4. AB - The reaction pathway for the rupture of the carbon-carbon double bond of C2 F4 has been calculated with ab initio methods at the CASSCF(8,8)+NEVPT2/aug-cc-pVTZ and CCSD(T)/aug-cc-pVTZ levels and with density functional theory using M06-L and M06-2X functionals in conjunction with aug-cc-pVTZ basis sets. The calculations suggest that the bond dissociation pathway proceeds by a nonlinear reaction course without an activation barrier yielding the CF2 fragments in the (1 A1 ) ground state. A bonding analysis indicates that there is a continuous change in the electronic structure of the CF2 fragments during the elongation of the C-C distance from a (3 B1 ) excited state at the equilibrium geometry of C2 F4 to the (1 A1 ) ground state. EDA-NOCV calculations suggest that the carbon-carbon interactions in C2 F4 at equilibrium distance and longer C-C values up to ~1.60 A are best described in terms of electron-sharing bonding between the CF2 fragments in the (3 B1 ) excited state. At longer distances, the situation changes toward dative bonding between CF2 fragments in the (1 A1 ) ground state. PMID- 29578618 TI - High-Impact Mechanical Loading Increases Bone Material Strength in Postmenopausal Women-A 3-Month Intervention Study. AB - Bone adapts to loading in several ways, including redistributing bone mass and altered geometry and microarchitecture. Because of previous methodological limitations, it is not known how the bone material strength is affected by mechanical loading in humans. The aim of this study was to investigate the effect of a 3-month unilateral high-impact exercise program on bone material properties and microarchitecture in healthy postmenopausal women. A total of 20 healthy and inactive postmenopausal women (aged 55.6 +/- 2.3 years [mean +/- SD]) were included and asked to perform an exercise program of daily one-legged jumps (with incremental number, from 3*10 to 4*20 jumps/d) during 3 months. All participants were asked to register their performed jumps in a structured daily diary. The participants chose one leg as the intervention leg and the other leg was used as control. The operators were blinded to the participant's choice of leg for intervention. The predefined primary outcome was change in bone material strength index (BMSi), measured at the mid tibia with a handheld reference probe indentation instrument (OsteoProbe). Bone microstructure, geometry, and density were measured with high-resolution peripheral quantitative computed tomography (XtremeCT) at the ultradistal and at 14% of the tibia bone length (distal). Differences were analyzed by related samples Wilcoxon signed rank test. The overall compliance to the jumping program was 93.6%. Relative to the control leg, BMSi of the intervention leg increased 7% or 0.89 SD (p = 0.046), but no differences were found for any of the XtremeCT-derived bone parameters. In conclusion, a unilateral high-impact loading program increased BMSi in postmenopausal women rapidly without affecting bone microstructure, geometry, or density, indicating that intense mechanical loading has the ability to rapidly improve bone material properties before changes in bone mass or structure.

PMID- 29578619 TI - Transport of Nucleoside Triphosphates into Cells by Artificial Molecular Transporters. AB - Chemically modified nucleoside triphosphates (NTPs) are widely exploited as unnatural metabolites in chemical biology and medicinal chemistry. Because anionic NTPs do not permeate cell membranes, their corresponding neutral precursors are employed in cell-based assays. These precursors become active metabolites after enzymatic conversion, which often proceeds insufficiently. Here we show that metabolically-active NTPs can be directly transported into eukaryotic cells and bacteria by the action of designed synthetic nucleoside triphosphate transporters (SNTTs). The transporter is composed of a receptor, which forms a non-covalent complex with a triphosphate anion, and a cell penetrating agent, which translocates the complex across the plasma membrane. NTP is then released from the complex in the intracellular milieu and accumulates in nuclei and nucleoli in high concentration. The transport of NTPs proceeds rapidly (seconds to minutes) and selectively even in the presence of other organic anions. We demonstrate that this operationally simple and efficient means of transport of fluorescently labelled NTPs into cells can be used for metabolic labeling of DNA in live cells.

AB - RATIONALE: Tocopherols and tocotrienols are chemical compounds insusceptible to the ionization process under atmospheric pressure conditions. Therefore, the selection of the optimal ion source settings for their quantification requires special attention. The aim of this study was to analyse the influence of the APCI source parameters on the response of tocochromanols and two related compounds. METHODS: Standard solutions of target compounds were injected on the high performance liquid chromatography/atmospheric pressure chemical ionization tandem mass spectrometry (HPLC/APCI-MS/MS) system separately and analysed with 30 randomly selected ion source settings. The obtained responses were modelled by multivariate linear regression with least absolute shrinkage and selection operator. The developed models were used to choose the best APCI conditions. RESULTS: Multivariate linear models were built for eight tocochromanols, trolox and BHT. The APCI settings derived from the models did not increase the peak areas obtained for T and T3 during the ionization process. Ionization conditions based on models for trolox and BHT improved analytical responses by 12-36% and 4 32%, respectively. The application of the ion source settings optimal for trolox and BHT to tocochromanols did not result in better analytical responses. CONCLUSIONS: The ionization pattern of tocochromanols in the APCI source is problematic and should be further investigated. Modelling methodology for response improvement presented in this study can be applied in similar studies.

AB - The site-selective functionalization of unactivated C(sp3 )-H bonds remains one of the greatest challenges in organic synthesis. Herein, we report on the site selective delta-C(sp3 )-H alkylation of amino acids and peptides with maleimides via a kinetically less favored six-membered palladacycle in the presence of more accessible gamma-C(sp3 )-H bonds. Experimental studies revealed that C-H bond cleavage occurs reversibly and preferentially at gamma-methyl over delta-methyl C H bonds while the subsequent alkylation proceeds exclusively at the six-membered palladacycle that is generated by delta-C-H activation. The selectivity can be explained by the Curtin-Hammett principle. The exceptional compatibility of this alkylation with various oligopeptides renders this procedure valuable for late stage peptide modifications. Notably, this process is also the first palladium(II)-catalyzed Michael-type alkylation reaction that proceeds through C(sp3 )-H activation.

AB - In situ and operando spectroscopic and microscopic methods were used to gain insight into the correlation between the structure, chemical state, and reactivity of size- and shape-controlled ligand-free Cu nanocubes during CO2 electroreduction (CO2 RR). Dynamic changes in the morphology and composition of Cu cubes supported on carbon were monitored under potential control through electrochemical atomic force microscopy, X-ray absorption fine-structure spectroscopy and X-ray photoelectron spectroscopy. Under reaction conditions, the roughening of the nanocube surface, disappearance of the (100) facets, formation of pores, loss of Cu and reduction of CuOx species observed were found to lead to a suppression of the selectivity for multi-carbon products (i.e. C2 H4 and ethanol) versus CH4 . A comparison with Cu cubes supported on Cu foils revealed an enhanced morphological stability and persistence of CuI species under CO2 RR in the former samples. Both factors are held responsible for the higher C2 /C1 product ratio observed for the Cu cubes/Cu as compared to Cu cubes/C. Our findings highlight the importance of the structure of the active nanocatalyst but also its interaction with the underlying substrate in CO2 RR selectivity.

AB - The simplest aminosulfinyl radical H2 NSO has been generated in the gas phase through flash vacuum pyrolysis of CF3 S(O)NH2 at approximately 1000 K. Upon UV light irradiation (365 nm), 1,3-H migration occurs in H2 NSO and furnishes an elusive N-amidyl radical HNSOH in syn and anti conformations in cryogenic matrices (N2 or Ar, 15 K). Further 266 nm laser irradiation results in dissociation of HNSOH to H2 O and SN and concomitant reformation of H2 NSO in trace amount. The identification of H2 NSO, syn-HNSOH, and anti-HNSOH by matrix isolation IR spectroscopy is supported by high-level quantum chemical computations. PMID- 29578624 TI - Robust Organocatalysts for the Cleavage of Vegetable Oil Derivatives to Aldehydes through Retrobenzoin Condensation. AB - A series of thiazolium salts was prepared and tested for the cleavage of the alpha-hydroxyketone derived from methyl oleate. The robustness of these precatalysts was determined by dynamic thermogravimetric analyses (TGA). It has been shown that the stability of these species is mainly governed by the nature of the counter-anion and some of them were found to be stable until 350-400 degrees C. The alpha-hydroxyketone derived from methyl oleate was cleaved under reactive distillation conditions using optimized, thermally robust N butylthiazolium triflate to give the cleavage product, namely, nonanal and methyl azelaaldehydate, with 85 and 70 % yields. A range of alpha-hydroxyketones derived from several fatty acids was cleaved to give the corresponding bio-based aldehydes with up to 98 % isolated yields. Finally, this protocol was successfully applied to a high-oleic sunflower oil derivative.

AB - BACKGROUND: Concomitant allergic contact dermatitis (ACD) has been described as a possible cause of atopic dermatitis (AD) becoming difficult-to-treat. However, contact sensitization in this patient group has barely been studied. OBJECTIVE: To study the occurrence of ACD in a population of difficult-to-treat AD children and adults. METHODS: Clinical and patch test information of 48 patients with difficult-to-treat AD unresponsive to conventional outpatient treatments was gathered retrospectively. We studied prevalence and relevance of common allergens, performed dynamic patch test analysis and assessed occurrence of polysensitization. RESULTS: In 48 patients with difficult-to-treat AD, 75% (n = 36/48) had a concomitant contact allergy, and 39% (n = 14/36) of these patients were polysensitized. ACD and polysensitization prevalences were equal amongst children and adults. The most frequent and relevant reactions were seen against wool alcohols, surfactants cocamidopropyl betaine and dimethylaminopropylamine, bichromate and fragrance mix I. Dynamic pattern analysis showed these reactions to be mostly allergic and not irritative of nature. CONCLUSION: Difficult-to treat AD patients frequently suffer from concomitant (multiple) contact allergies, and this may be a reason why the AD turns into a difficult-to-treat disease. Awareness of this phenomenon is necessary, as pragmatic implementation of allergen avoidance strategies may be helpful in getting disease control in this population. PMID- 29578628 TI - Assessment of two screening tools to identify psoriatic arthritis in patients with psoriasis. AB - BACKGROUND: Many patients with psoriasis have undiagnosed psoriatic arthritis. Low specificity is found with many PsA screening tools. A new instrument, the CONTEST questionnaire, was developed utilizing the most discriminative items from existing instruments. OBJECTIVE: The aim of this study was to compare the CONTEST and PEST screening tools. METHODS: People attending secondary care clinics with psoriasis, but not PsA, completed the questionnaires, were assessed for function and quality of life, and had a physical examination. Patients thought to have PsA were compared to those without. The performance of CONTEST and PEST was compared using area under the receiver operating curve (AUC), and sensitivity and specificity at the previously published cut-offs. RESULTS: A total of 451 dermatology patients were approached, 35% were reviewed and 27 (17%, 95% CI 12.3 21.7) had unidentified psoriatic arthritis. The sensitivity and specificity (95% CI) of PEST were 0.60 (0.42-0.78)/0.76 (0.69-0.83) and for CONTEST 0.53 (0.34 0.72)/0.71 (0.63-0.79). The confidence limits for the AUC overlapped (AUC for PEST 0.72 (0.61-0.84), for CONTEST 0.66 (0.54-0.77). CONCLUSIONS: PEST and CONTEST questionnaires performed equally well, with no superiority of the new CONTEST tool. PMID- 29578629 TI - Response to Mroczkowski. PMID- 29578630 TI - Outcomes of radiation therapy of indolent cutaneous B-cell lymphomas and literature review. AB - BACKGROUND: Primary cutaneous B-cell lymphomas represent approximately 25% of primary cutaneous lymphomas. Follicular centre cell lymphomas (PCFCL) and marginal zone lymphomas (PCMZL) are the two histological subtypes that present an indolent evolution. Radiotherapy is one of the recommended treatment options with few series reported. OBJECTIVE: This study aimed to evaluate radiotherapy outcomes in term of overall survival (OS) and disease-free survival (DFS) for patients suffering from a PCMZL or PCFCL, to search for predictive factors of recurrence, and to evaluate chronic and aesthetics adverse events and patient's satisfaction. METHODS: Patients treated with contact low energy radiotherapy for a PMZCL or PCFCL from April 2009 to June 2017 in Saint Louis hospital were retrospectively analysed. Total dose ranged from 18 to 30 Gy. Objective response (OR) rates, DFS and OS as patterns of recurrence according to radiation fields were analysed. Univariate analysis of DFS has been performed according to clinical and biological parameters. Acute toxicity, long-term adverse events and satisfaction were collected via individualized questionnaires. RESULTS: Forty-six patients were included. Median follow-up was 43.5 months. OR was achieved for 100% of cases. Recurrence occurred in 39% of cases. Median DFS was 44 months. Three-year DFS and 5-year DFS were 56% and 51%, respectively. OS at 3 and 5 year was 100%. Only sex was significantly associated with DFS. Acute AEs occurred in 48% of cases without grade 3 and 4. 55% reported some moderate aesthetic sequelae for long-term AEs. 97% were satisfied with treatment. CONCLUSION: This study confirms the good risk-benefit of radiotherapy for the treatment of primary cutaneous indolent B-cell lymphomas due to the high response rate and a long DFS. No significant factor for recurrence was identified, except female sex. Long-term aesthetic evaluation was good or excellent for most of the patients. PMID- 29578631 TI - Coordination in theory, coordination in practice: the case of the Clusters. AB - The atomised nature of the humanitarian system has led to frequent and repeated attempts to coordinate humanitarian activity. Since 2005, some of the best resourced, and arguably most successful, coordination mechanisms have been the humanitarian Clusters, groups of UN (United Nations) and non-UN actors that engage in sectoral coordination of humanitarian response (such as the provision of healthcare and water) at the global and country level. Nevertheless, it is not clear exactly what 'coordination' means in the context of a Cluster. Formal guidance suggests that they should be aiming to create a single, joint strategy to guide the activities of members. Actual experience of the Clusters, however, indicates that looser forms of coordination are more effective. This finding resonates with organisational theory, and with the experience of emergency management professionals beyond the international humanitarian sector. To capitalise fully on the success of the Clusters, policymakers may need to rethink their attitudes to, and expectations of, coordination.

AB - The intracellular adaptor protein Mint2 binds amyloid precursor protein (APP) and presenilin-1, which are both central constituents of the amyloidogenic pathway associated with Alzheimer's disease (AD). Additional interaction partners have also been suggested for Mint2; several of them are also pertinent to AD pathogenesis. However, no comparative mapping of the Mint2 protein-protein interaction network is available. Here we provide a systematic characterization of seven interaction partners and address their specificities towards the different binding domains of Mint2, which reveal domain-specific and -nonspecific interaction partners. Moreover, we show that the last two C-terminal amino acids of Mint2 are both important for the intramolecular interaction with the PDZ1 domain and for the stability of Mint2. PMID- 29578634 TI - mTOR: A double-edged sword for diabetes. AB - Diabetes is both a metabolic and an immune disorder. One intriguing link between the two is the serine-threonine protein kinase mammalian target of rapamycin (mTOR). As a component of the PI3K/Akt pathway and other cellular signals, mTOR is a key regulator of fuel metabolism and function of both pancreatic islet beta cells and immune cells. Consequently, it seems that mTOR has both anti- and prodiabetic effects. On the one hand, activation of mTOR in beta cells can increase their growth and proliferation, opposing impairments of insulin secretion in diabetes. On the other, activation of mTOR signaling in specific immune cells alters their fuel metabolism, amplifying their contributions to beta cell dysfunction, contributing to the development of diabetes. In this review, we focus on roles of mTOR signaling in pancreatic beta cells and immune cells and their implications in the pathogenesis and treatment of diabetes.

AB - BACKGROUND: Mechanical hyperkeratotic lesions (MHL) are common condition amongst population of all ages. Such problems may be associated with pain, reduction in mobility, changes of gait and risk of falls and is believed to affect the quality of life (QoL), general health and optimal foot health. OBJECTIVE: The main aim of this study was to describe and compare both foot and general health-related QoL in two groups of participants: (i) with MHL and (ii) healthy controls. METHOD: A total sample of 150 patients, mean age 49.50 +/- 36.50 years, was recruited from an outpatient clinic. Demographic data, medical history and clinical characteristics of overall health were determined, and the obtained values were compared by the Foot Health Status Questionnaire (FHSQ). RESULTS: The FHSQ scores of the sample with MHL showed lower scores than control subjects in sections one and two for footwear, general and foot health, foot pain, foot function and physical activity (P < 0.01), but not for social capacity and vigour (P > 0.01). CONCLUSIONS: People with MHL showed a decrease in QoL, based on FHSQ scores, regardless of gender. PMID- 29578636 TI - Octacarbonyl Anion Complexes of Group Three Transition Metals [TM(CO)8 ]- (TM=Sc, Y, La) and the 18-Electron Rule. AB - We report the gas-phase synthesis of stable 20-electron carbonyl anion complexes of group 3 transition metals, TM(CO)8- (TM=Sc, Y, La), which are studied by mass selected infrared (IR) photodissociation spectroscopy. The experimentally observed species, which are the first octacarbonyl anionic complexes of a TM, are identified by comparison of the measured and calculated IR spectra. Quantum chemical calculations show that the molecules have a cubic (Oh ) equilibrium geometry and a singlet (1 A1g ) electronic ground state. The 20-electron systems TM(CO)8- are energetically stable toward loss of one CO ligand, yielding the 18 electron complexes TM(CO)7- in the 1 A1 electronic ground state; these exhibit a capped octahedral structure with C3v symmetry. Analysis of the electronic structure of TM(CO)8- reveals that there is one occupied valence molecular orbital with a2u symmetry, which is formed only by ligand orbitals without a contribution from the metal atomic orbitals. The adducts of TM(CO)8- fulfill the 18-electron rule when only those valence electrons that occupy metal-ligand bonding orbitals are considered. PMID- 29578637 TI - The role of Confucianism in South Korea's emergency management system. AB - Numerous Western researchers have examined the influence of Confucianism on development in Asia, but almost no South Korean researchers have studied the topic in regard to emergency management in their own country. This study begins by considering Confucianism as a social culture. Next, it goes on to evaluate its role in South Korea's emergency management system, contributing, ultimately, to efficiencies in emergency management. Drawing on a literature review and a case study, the paper assesses the double- and single-faced approaches, using four major Confucian components: destiny; family; ritual; and relation. The double faced approach includes the positive and negative aspects of emergency management, whereas the single-faced approach incorporates only its positive aspects. This paper provides, for the first time, a systematic analysis of the relationship between Confucianism and emergency management in South Korea. Its key finding is that the double-faced approach needs to be transformed into a single-faced approach through active facilitation of behavioural change. PMID- 29578638 TI - Evaluation of the analytical variability of dipstick protein pads in canine urine. AB - BACKGROUND: The dipstick is a first-line and inexpensive test that can exclude the presence of proteinuria in dogs. However, no information is available about the analytical variability of canine urine dipstick analysis. OBJECTIVES: The aim of this study was to assess the analytical variability in 2 dipsticks and the inter-operator variability in dipstick interpretation. METHODS: Canine urine supernatants (n = 174) were analyzed with 2 commercially available dipsticks. Two observers evaluated each result blinded to the other observer and to the results of the other dipstick. Intra- and inter-assay variability was assessed in 5 samples (corresponding to the 5 different semi-quantitative results) tested 10 consecutive times over 5 consecutive days. The agreement between observers and between dipsticks was evaluated with Cohen's k test. RESULTS: Intra-assay repeatability was good (<=3/10 errors), whereas inter-assay variability was higher (from 1/5 to 4/5 discordant results). The concordance between the operators (k = 0.68 and 0.79 for the 2 dipsticks) and that of the dipsticks (k = 0.66 and 0.74 for the 2 operators) was good. However, 1 observer and 1 dipstick overestimated the results compared with the second observer or dipstick. In any case, discordant results accounted for a single unit of the semi-quantitative scale. CONCLUSIONS: As for any other method, analytic variability may affect the semi-quantitation of urinary proteins when using the dipstick method. Subjective interpretation of the pad and, to a lesser extent, intrinsic staining properties of the pads could affect the results. Further studies are warranted to evaluate the effect of this variability on clinical decisions. PMID- 29578639 TI - Hormone modulation of legume-rhizobial symbiosis.

The formation of nitrogen-fixing nodules requires coordinating rhizobial infection and root nodule organogenesis. The formation of an infection thread and the extent of nodule formation are largely under plant control, but vary with environmental conditions and the physiological state of the host plants. Many achievements in these two areas have been made in recent decades. Phytohormone signaling pathways have gradually emerged as important regulators of root nodule symbiosis. Cytokinin, strigolactones (SLs) and local accumulation of auxin can promote nodule development. Ethylene, jasmonic acid (JA), abscisic acid (ABA) and gibberellic acid (GA) all negatively regulate infection thread formation and nodule development. However, salicylic acid (SA) and brassinosteroids (BRs) have different effects on the formation of these two nodule types. Some peptide hormones are also involved in nodulation. This review summarizes recent findings on the roles of these plant hormones in legume-rhizobial symbiosis, and we propose that DELLA proteins may function as a node to integrate plant hormones to regulate nodulation. PMID- 29578640 TI - Taste and Flavor Perceptions of Glucosinolates, Isothiocyanates, and Related Compounds. AB - Brassicaceae plants are renowned for their taste, aroma and trigeminal characteristics; predominantly bitter taste, sulfurous aroma, and pungency. Compounds responsible for these sensations include the glucosinolates (GSLs) and their hydrolysis products, particularly isothiocyanates (ITCs), but also sulfur containing volatile compounds. This article reviews the relative importance of taste and flavor perceptions resulting from such compounds; collating evidence from papers where findings are based on sensory analytical correlations, and those that have extracted specific compounds prior to sensory evaluation. Where specific GSLs impart bitterness and many ITCs impart pungency, this is clearly not true for all GSLs and ITCs. Designing crop improvement strategies for sensory traits based on total GSL content would be flawed, as it does not consider the relative differences in sensory characteristics of different GSLs and ITCs, nor the contribution from other GSL hydrolysis products. In addition, some Brassicaceae plants are consumed raw, whilst others are cooked; this affects not only the hydrolysis of GSLs, but also the generation and release of sulfides. Therefore, in breeding new plant varieties, it is prudent to consider the individual GSLs, the typical cooking conditions the plant is subjected to, enzyme stability, and resultant composition of both GSL hydrolysis products (including ITCs) and sulfides. PMID- 29578641 TI - Comparative susceptibility and immune responses of Asian and European honey bees to the American foulbrood pathogen, Paenibacillus larvae. AB - American foulbrood (AFB) disease is caused by Paenibacillus larvae. Currently, this pathogen is widespread in the European honey bee-Apis mellifera. However, little is known about infectivity and pathogenicity of P. larvae in the Asiatic cavity-nesting honey bees, Apis cerana. Moreover, comparative knowledge of P. larvae infectivity and pathogenicity between both honey bee species is scarce. In this study, we examined susceptibility, larval mortality, survival rate and expression of genes encoding antimicrobial peptides (AMPs) including defensin, apidaecin, abaecin, and hymenoptaecin in A. mellifera and A. cerana when infected with P. larvae. Our results showed similar effects of P. larvae on the survival rate and patterns of AMP gene expression in both honey bee species when bee larvae are infected with spores at the median lethal concentration (LC50 ) for A. mellifera. All AMPs of infected bee larvae showed significant upregulation compared with noninfected bee larvae in both honey bee species. However, larvae of A. cerana were more susceptible than A. mellifera when the same larval ages and spore concentration of P. larvae were used. It also appears that A. cerana showed higher levels of AMP expression than A. mellifera. This research provides the first evidence of survival rate, LC50 and immune response profiles of Asian honey bees, A. cerana, when infected by P. larvae in comparison with the European honey bee, A. mellifera. PMID- 29578642 TI - Immune configuration in hatchling snakes is affected by incubation moisture, and is linked to subsequent growth and survival in the field. AB - We incubated the eggs of field-caught keelback snakes (Tropidonophis mairii) on wet versus dry substrates to explore impacts of incubation conditions on white blood cell (WBC) concentrations and differential WBC counts of hatchlings. In a second, independent study young snakes were released into the field, allowing us to explore fitness correlates of WBC profiles. Dry incubation reduced embryonic survival and hatchling body size, thus decoupling egg size from hatchling size. Incubation conditions also altered WBC profiles. Lymphocyte and azurophil counts were related to hatchling body size but not to initial egg mass, whereas heterophil counts were related to both of these traits. The egg-size effect on heterophil counts may reflect a maternal effect on offspring immune configuration. The ratio of heterophils to lymphocytes (an index of stress) was higher in hatchlings from eggs incubated on dry substrates. Snakes with higher counts of lymphocytes at hatching were more likely to be recaptured as adults (H:L; an index of survival), whereas snakes with higher basophil counts exhibited more rapid growth. In summary, our experiments show that incubation moisture levels influence the immune configuration of hatchling snakes, and that variation among individuals in WBC counts at hatching is a significant predictor of an individual's fitness after it is released into the wild. The demonstrated link between incubation conditions and offspring fitness is likely to impose strong selection on maternal nest-site choice. PMID- 29578643 TI - Arabidopsis thaliana NOP10 is required for gametophyte formation. AB - The female gametophyte is crucial for sexual reproduction of higher plants, yet little is known about the molecular mechanisms underlying its development. Here, we report that Arabidopsis thaliana NOP10 (AtNOP10) is required for female gametophyte formation. AtNOP10 was expressed predominantly in the seedling and reproductive tissues, including anthers, pollen grains, and ovules. Mutations in AtNOP10 interrupted mitosis of the functional megaspore during early development and prevented polar nuclear fusion in the embryo sacs. AtNOP10 shares a high level of amino acid sequence similarity with Saccharomyces cerevisiae (yeast) NOP10 (ScNOP10), an important component of the H/ACA small nucleolar ribonucleoprotein particles (H/ACA snoRNPs) implicated in 18S rRNA synthesis and rRNA pseudouridylation. Heterologous expression of ScNOP10 complemented the mutant phenotype of Atnop10. Thus, AtNOP10 influences functional megaspore mitosis and polar nuclear fusion during gametophyte formation in Arabidopsis. PMID- 29578644 TI - Point of care diaphragm ultrasound in infants with bronchiolitis: A prospective study. AB - BACKGROUND: Bronchiolitis is the most common reason for hospitalization of children worldwide. Many scoring systems have been developed to quantify respiratory distress and predict outcome, but none of them have been validated. We hypothesized that the ultrasound evaluation of the diaphragm could quantify respiratory distress and therefore we correlated the ultrasound diaphragm parameters with outcome. METHODS: Prospective study of infants with bronchiolitis (1-12 months) evaluated in a pediatric emergency department. Ultrasonography examinations of the diaphragm was performed (diaphragm excursion [DE], inspiratory excursion [IS], inspiratory/expiratory relationship [I/E], and thickness at end-expiration [TEE] and at end-inspiration [TEI]; thickening fraction [TF]). RESULTS: We evaluated 61 infants, 50.8 % males. Mean TF was 47% (IQR 28.6-64.7), mean I/E 0.47 (+/- 0.15), mean DE 10.39 +/- 4 mm. There was a linear correlation between TF and oxygen saturation at first evaluation (P = 0.006, r = 0.392). All children with lower values of TF required HFNC and one of them required CPAP. A higher IS was associated with the future need of respiratory support during admission (P = 0.007). IS correlated with the hours of oxygen delivery needed (P = 0.032, r = 0.422). TEI (t = 3.701, P = 0.002) was found to be main predictor of hours of oxygen delivery needed. CONCLUSION: This study described ultrasound diaphragmatic values of previously healthy infants with bronchiolitis. DE, IS, and TEI correlated with outcome. If confirmed in larger studies, bedside ultrasound semiology of the diaphragm can be a new objective tool for the evaluation and outcome prediction of infants with bronchiolitis.

PMID- 29578646 TI - Pharmacokinetics, Safety, and Tolerability of Lamotrigine Chewable/Dispersible Tablet Following Repeat-Dose Administration in Healthy Chinese Volunteers. AB - In this open-label, single-center study, the pharmacokinetics, safety, and tolerability of lamotrigine chewable/dispersible tablets were assessed in healthy Chinese volunteers. Each volunteer (N = 16) received repeat doses of oral lamotrigine titrated from 25 mg to 50 mg to 100 mg over 42 days and was followed up for 10-17 days. Safety and tolerability were assessed throughout the study. Lamotrigine pharmacokinetic parameters were estimated using noncompartmental analysis. Overall, 15 (94%) volunteers completed the study. Lamotrigine serum concentrations peaked 2.5 hours postdose, with a mean terminal half-life of 36.8 hours. The apparent lamotrigine oral clearance was 1577.88 mL/h. The accumulation ratios (day 14 vs day 1) were 2.53 and 2.58 for area under the curve and peak concentration, respectively. Lamotrigine 25 to 100 mg once daily exhibited dose proportional pharmacokinetics (based on area under the curve and peak concentration), following repeat dosing. Nine volunteers reported adverse events, 2 experienced oropharyngeal pain, each receiving 25 mg and 50 mg. One volunteer withdrew due to an increase in liver enzymes. No deaths, serious adverse effects, or skin rashes were reported during the study. No new safety concerns were observed. Overall, the pharmacokinetic profiles after repeat doses of lamotrigine chewable/dispersible tablets once daily in a Chinese population were similar to those observed in Western populations. PMID- 29578647 TI - Bioequivalence of Two Formulations of Gliclazide in a Randomized Crossover Study in Healthy Caucasian Subjects Under Fasting Conditions. AB - This study aimed to investigate the bioequivalence of 2 formulations of gliclazide modified-release tablets 60 mg in 48 healthy Caucasian volunteers under fasting conditions. A test product, Gliclazide MR (Ranbaxy Laboratories Limited, now Sun Pharmaceutical Industries, India), was compared with a reference product, Diamicron MR (Servier, France). The study was performed under a single dose, 2-treatment, 2-period, 2-sequence crossover design in a fasted condition with a washout period of 21 days. Blood samples were collected for 96 hours after drug administration. Drug plasma concentrations were determined by a liquid chromatography-tandem mass spectrometry method. Analysis of pharmacokinetic characteristics was based on a noncompartmental model. The logarithmically transformed data of Cmax and AUC were analyzed for 90% confidence intervals using analysis of variance. There was no significant difference in pharmacokinetic characteristics between the products, and the 90% confidence intervals were within the acceptance range of 80.00%-125.00%. The investigated products were bioequivalent under fasted conditions. PMID- 29578649 TI - Assessing the impact of the Graduate Certificate in Anatomical Sciences Instruction: A post-degree survey. AB - There are few graduate programs available for pursuing a doctorate in anatomy where students gain specific training in gross anatomy dissection and the responsibilities of a medical educator. In light of this fact, the University of Kentucky created a Graduate Certificate in Anatomical Sciences Instruction in 2006. This 12-credit hour curriculum includes detailed training in gross anatomy and/or neuroscience courses, practicum experiences, a seminar class in pedagogical literature, and a course in educational strategies for the anatomical sciences. The award of certificate completion affirms that the candidate has demonstrated faculty-supervised proficiency in anatomy dissection, instruction in anatomy topics, and teaching strategies for anatomy. Seventeen graduate students have earned the certificate since its inception; nine students accepted teaching positions in anatomy following their graduate training and currently nine certificate graduates have assistant (six) or associate (three) professor positions in academia. In 2016, an anonymous survey including Likert-style and open-ended questions was emailed to all certificate graduates. Graduates favorably responded (each question averaged 4.4 or greater out of 5) that the certificate increased their awareness of teaching-faculty responsibilities, adequately prepared them for teaching-related duties, and positively contributed toward their first employment. Graduates indicated that the lecturing and dissection experience, awareness of faculty responsibilities, and job preparation (e.g., teaching philosophy development) were the most helpful aspects of the certificate. These results indicate that the Graduate Certificate in Anatomical Sciences Instruction is viewed by its graduates and their employers as a valuable teaching credential that can be attained alongside a basic science degree.

AB - Epigenetics is a rapidly growing field in drug discovery. Of particular interest is the role of post-translational modifications to histones and the proteins that read, write, and erase such modifications. The development of inhibitors for reader domains has focused on single domains. One of the major difficulties of designing inhibitors for reader domains is that, with the notable exception of bromodomains, they tend not to possess a well-enclosed binding site amenable to small-molecule inhibition. As many of the proteins in epigenetic regulation have multiple domains, there are opportunities for designing inhibitors that bind at a domain-domain interface which provide a more suitable interaction pocket. Examination of X-ray structures of multiple domains involved in recognising and modifying post-translational histone marks using the SiteMap algorithm identified potential binding sites at domain-domain interfaces. For the tandem plant homeodomain-bromodomain of SP100C, a potential inter-domain site identified computationally was validated experimentally by the discovery of ligands by X-ray crystallographic fragment screening. PMID- 29578650 TI - Quantification of alignment of vascular smooth muscle cells. AB - Vascular smooth muscle cells (VSMCs) are essential components that keep the tonus of the arterial network, which is the channel used to conduct the blood from the heart to the peripheral areas of the body. It is known that mechanical and architectural changes in VSMCs may lead to functional modifications in the cardiovascular system; therefore, the quantitative characterization of these changes can help to elucidate questions that remain unclear in pathological situations, such as hypertension, vasospasm, vascular hypertrophy, and atherosclerosis. In this work, we have developed a new framework of image processing using the Sobel operator, associated with statistical analysis, to determine the degree of local alignment of actin filaments, which we found to be directly related with the distensibility of the arterial wall. We have also compared these results with the rigidity of the cytoskeleton of VSMCs. The results suggest that the alignment degree increases from peripheral arteries, such as carotid and femoral, to central arteries, as well coronary and thoracic aorta, which can indicate that the level of local alignment of the actin fibers in VSMCs is related with the mechanical behavior of the arterial wall.

AB - Poly(3-hydroxybutyrate-co-4-hydroxybutyrate), P(3HB-co-4HB), is one of the most valuable biopolymers because of its flexible mechanical properties. In this study, the goal is to establish a scaled-up process of low cost P(3HB-co-4HB) from a 7.5-L fermentor to 1- and 5-m3 industrial bioreactors, respectively, using Halomonas bluephagenesis TD40 grown on glucose, gamma-butyrolactone, and waste corn steep liquor (CSL) as substrates, under open non-sterile and fed-batch or continuous conditions. The non-sterile process enables the energy reduction for less steam consumption. Moreover, waste gluconate is successfully utilized to replace glucose as a carbon source for cell growth and PHA accumulation in 7.5-L fermentor, which opens the possibility of 60% of raw material cost reduction for recycling the waste resources. A mathematical model and rational calculation is established to help guide the feeding strategy and scale-up, respectively, leading to 100 g L-1 cell dry weight (CDW) containing 60.4% P(3HB-co-mol 13.5% 4HB) after 36 h of growth in the 5 m3 vessel. An even higher P(3HB-co-4HB) content of 74% is achieved by decreasing the use of waste CSL. A stable and continuous open process for efficient low-cost production of P(3HB-co-4HB) is successfully developed coupling fermentation with the downstream extraction processing. PMID- 29578652 TI - Non-Celiac Gluten Sensitivity: How Its Gut Immune Activation and Potential Dietary Management Differ from Celiac Disease. AB - Non-celiac gluten sensitivity (NCGS) is a clinical entity triggered by the ingestion of gluten-containing grains leading to intestinal and/or extraintestinal symptoms that resolve once the gluten-containing foodstuff is eliminated from the diet, and it is diagnosed when celiac disease (CD) and wheat allergy (WA) have been ruled out. The limited knowledge about the pathophysiology of NCGS and the lack of validated biomarkers are still major limitations for clinical studies, making it difficult to differentiate NCGS from other gluten related disorders (GRD). In the absence of clear-cut diagnostic criteria, NCGS is still mainly a diagnosis of exclusion. Several studies suggest that NCGS is an immune-mediated disease that likely activates an innate immune response. Moreover, it has recently been hypothesized that in addition to gluten, other components of wheat may be responsible for the symptoms observed in individuals without CD. This review aims at discussing available evidence related to the histological and immunological features in the gut mucosa of patients with NCGS and at outlining new dietary opportunities for these patients. PMID- 29578653 TI - Diagnostic accuracy and therapeutic relevance of thoracoscopic lung biopsies in children. AB - INTRODUCTION: Histopathological assessment of lung biopsies does play an important diagnostic role in children's interstitial lung disease (ChILD). Thoracoscopic lung biopsy has been shown to be safe and effective. The aim of this study was to evaluate the diagnostic accuracy of thoracoscopic lung biopsies in children with ChILD. Furthermore, therapeutic relevance of the procedure, operative details, and perioperative complications of our series were investigated. METHODS: We retrospectively reviewed all consecutive thoracoscopic lung biopsies taken from children with suspected ChILD in our institution over an 11-year period. Feasibility and complications were evaluated as well as histopathological diagnoses according to the recent ChILD classification and relevance of the procedure for medical treatment. RESULTS: Fifty-nine patients (54.2% male, median age 7 years [8 d-18 y]) underwent 112 thoracoscopic lung biopsies. An endostapler (27%), endoloop ligature (63%), or cut and suture technique (10%) were used. A chest tube was placed in 54% of the cases. Complications occurred in 15% of cases and mainly consisted of pneumothoraces or bleedings. Adequate tissue was obtained in all but one case and the biopsy led to a specific diagnosis according to the ChILD classification in 98%. Medical treatment of the underlying disease was changed due to the results of the biopsy in 86%. CONCLUSIONS: The diagnostic accuracy of thoracoscopic lung biopsies in children with suspected ChILD is high. The histopathologic results lead to a disease-specific treatment in the majority of the cases. Thoracoscopic lung biopsy is a safe and effective procedure with a low complication rate. PMID- 29578654 TI - Typological thinking: Then and now. AB - A popular narrative about the history of modern biology has it that Ernst Mayr introduced the distinction between "typological thinking" and "population thinking" to mark a contrast between a metaphysically problematic and a promising foundation for (evolutionary) biology, respectively. This narrative sometimes continues with the observation that, since the late-20th century, typological concepts have been making a comeback in biology, primarily in the context of evolutionary developmental biology. It is hard to square this narrative with the historical and philosophical literature on the typology/population distinction from the last decade or so. The conclusion that emerges from this literature is that the very distinction between typological thinking and population thinking is a piece of mere rhetoric that was concocted and rehearsed for purely strategic, programmatic reasons. If this is right, it becomes hard to make sense of recent criticisms (and sometimes: espousals) of the purportedly typological underpinnings of certain contemporary research programs. In this article, I offer a way out of this apparent conflict. I show that we can make historical and philosophical sense of the continued accusations of typological thinking by looking beyond Mayr, to his contemporary and colleague George Gaylord Simpson. I show that before Mayr discussed the typology/population distinction as an issue in scientific metaphysics, Simpson introduced it to mark several contrasts in methodology and scientific practice. I argue that Simpson's insightful discussion offers useful resources for classifying and assessing contemporary attributions of typological thinking.

AB - BACKGROUND: Thrombin plays a central role in hemostasis and thrombosis. Calibrated automated thrombography (CAT), a thrombin generation assay, may be a useful test for hemostatic disorders in dogs. OBJECTIVES: To describe CAT results in a group of healthy dogs, and assess preanalytical variables and biological variability. ANIMALS: Forty healthy dogs were enrolled. METHODS: Lag time (Lag), time to peak (ttpeak), peak thrombin generation (peak), and endogenous thrombin potential (ETP) were measured. Direct jugular venipuncture and winged-needle catheter-assisted saphenous venipuncture were used to collect samples from each dog, and results were compared between methods. Sample stability at -80 degrees C was assessed over 12 months in a subset of samples. Biological variability of CAT was assessed via nested ANOVA using samples obtained weekly from a subset of 9 dogs for 4 consecutive weeks. RESULTS: Samples for CAT were stable at -80 degrees C over 12 months of storage. Samples collected via winged-needle catheter venipuncture showed poor repeatability compared to direct venipuncture samples; there was also poor agreement between the 2 sampling methods. Intra-individual variability of CAT parameters was below 25%; inter-individual variability ranged from 36.9% to 78.5%. CONCLUSIONS: Measurement of thrombin generation using CAT appears to be repeatable in healthy dogs, and samples are stable for at least 12 months when stored at -80 degrees C. Direct venipuncture sampling is recommended for CAT. Low indices of individuality suggest that subject-based reference intervals are more suitable when interpreting CAT results.

AB - The reduced costs of DNA sequencing and the use of such data for HIV-1 clinical management and phylogenetic analysis have led to a massive increase of HIV-1 sequences in the last few years. Phylogenetic analysis has shed light on the origin, spread and characteristics of HIV-1 epidemics and outbreaks. Phylogenetic analysis is now also being used to advance our knowledge of the drivers of HIV-1 transmission in order to design effective interventions. However, HIV phylogenetic analysis presents unique ethical challenges, which have not been fully explored. This review presents an analysis of what appear to be key ethical issues in HIV phylogenetics in the hope of stimulating further conceptual and empirical work in this rapidly emerging area. We structure the review using the Emanuel Framework, a systematic, holistic framework, which has been adapted for use in developing countries, which bear the brunt of the HIV-1 pandemic. PMID- 29578673 TI - Ligand-Based Phase Control in Porous Molecular Assemblies. AB - Functionalization of isophthalic acid ligands with linear alkoxide groups from ethoxy through pentoxy is shown to have a pronounced effect on both the synthesis of porous paddlewheel-based molecular assemblies and their resulting surface areas and gas adsorption properties. Shorter chain length is compatible with either tetragonal or hexagonal two-dimensional materials, with the hexagonal phase favored with longer chain length. Precise tuning of reaction conditions affords discrete molecular species that are soluble in a variety of organic solvents. The isolated porous molecules display BET surface areas ranging from 125 m2/g to 545 m2/g. The pentoxide-based molecular assembly shows considerable promise for the separation of hydrocarbons with average isosteric heats of adsorption of -48 and -31 kJ/mol for ethylene and ethane, respectively. PMID- 29578659 TI - Drilling and Production Activity Related to Unconventional Gas Development and Severity of Preterm Birth. AB - BACKGROUND: Studies of unconventional gas development (UGD) and preterm birth (PTB) have not presented risk estimates by well development phase or trimester. OBJECTIVE: We examined phase and trimester-specific associations between UGD activity and PTB. METHODS: We conducted a case-control study of women with singleton births in the Barnett Shale area, Texas, from 30 November 2010 to 29 November 2012. We individually age- and race/ethnicity-matched five controls to each PTB case (n=13,328) and truncated controls' time at risk according to the matched case's gestational age. We created phase-specific UGD-activity metrics: a) inverse squared distance-weighted (IDW) count of wells in the drilling phase <=0.5 mi (804.7 meters) of the residence and b) IDW sum of natural gas produced <=0.5 mi of the residence. We also constructed trimester- and gestation-specific metrics. Metrics were categorized as follows: zero wells (reference), first, second, third tertiles of UGD activity. Analyses were repeated by PTB severity: extreme, very, and moderate (<28, 28 to<32, and 32 to<37 completed weeks). Data were analyzed using conditional logistic regression. RESULTS: We found increased odds of PTB in the third tertile of the UGD drilling {odds ratio (OR)=1.20 [95% confidence interval (CI): 1.06, 1.37]} and UGD-production [OR=1.15 (1.05, 1.26)] metrics. Among women in the third tertile of UGD-production, associations were strongest in trimesters one [OR=1.18 (1.02, 1.37)] and two [OR=1.14 (0.99, 1.31). The greatest risk was observed for extremely PTB [third tertile ORs: UGD drilling, 2.00 (1.23, 3.24); UGD production, 1.53 (1.03-2.27)]. CONCLUSIONS: We found evidence of differences in phase- and trimester-specific associations of UGD and PTB and indication of particular risk associated with extremely preterm birth. Future studies should focus on quantifying specific chemical and nonchemical stressors associated with UGD. https://doi.org/10.1289/EHP2622. PMID- 29578674 TI - Proteomic Characterization of the Neural Ectoderm Fated Cell Clones in the Xenopus laevis Embryo by High-Resolution Mass Spectrometry. AB - The molecular program by which embryonic ectoderm is induced to form neural tissue is essential to understanding normal and impaired development of the central nervous system. Xenopus has been a powerful vertebrate model in which to elucidate this process. However, abundant vitellogenin (yolk) proteins in cells of the early Xenopus embryo interfere with protein detection by high-resolution mass spectrometry (HRMS), the technology of choice for identifying these gene products. Here, we systematically evaluated strategies of bottom-up proteomics to enhance proteomic detection from the neural ectoderm (NE) of X. laevis using nanoflow high-performance liquid chromatography (nanoLC) HRMS. From whole embryos, high-pH fractionation prior to nanoLC-HRMS yielded 1319 protein groups vs 762 proteins without fractionation (control). Compared to 702 proteins from dorsal halves of embryos (control), 1881 proteins were identified after yolk platelets were depleted via sucrose-gradient centrifugation. We combined these approaches to characterize protein expression in the NE of the early embryo. To guide microdissection of the NE tissues from the gastrula (stage 10), their precursor (midline dorsal-animal, or D111) cells were fate-mapped from the 32 cell embryo using a fluorescent lineage tracer. HRMS of the cell clones identified 2363 proteins, including 147 phosphoproteins (without phosphoprotein enrichment), transcription factors, and members from pathways of cellular signaling. In reference to transcriptomic maps of the developing X. laevis, 76 proteins involved in signaling pathways were gene matched to transcripts with known enrichment in the neural plate. Besides a protocol, this work provides qualitative proteomic data on the early developing NE. PMID- 29578675 TI - Polymer-Assisted Single Crystal Engineering of Organic Semiconductors To Alter Electron Transport. AB - A new crystal phase of a naphthalenediimide derivative (alpha-DPNDI) has been prepared via a facial polymer-assisted method. The stacking pattern of DPNDI can be tailored from the known one-dimensional (1D) ribbon (beta phase) to a novel two-dimensional (2D) plate (alpha phase) through the assistance from polymers. We believe that the presence of polymers during crystal growth is likely to weaken the direct pi-pi interactions and favor side-to-side C-H-pi contacts. Furthermore, beta phase architecture shows electron mobility higher than that of the alpha phase in the single-crystal-based OFET. Theoretical calculations not only confirm that beta-DPNDI has an electron transport performance better than that of the alpha phase but also indicate that the alpha phase crystal displays 2D transport while the beta phase possesses 1D transport. Our results clearly suggest that polymer-assisted crystal engineering should be a promising approach to alter the electronic properties of organic semiconductors. PMID- 29578676 TI - Exploratory Study of Zn xPbO y Photoelectrodes for Unassisted Overall Solar Water Splitting. AB - A complete photoelectrochemical (PEC) water splitting system requires a photocathode and a photoanode to host water oxidation and reduction reactions, respectively. It is thus important to search for efficient photoelectrodes capable of full water splitting. Herein, we report on an exploratory study of a new photoelectrode family of Zn xPbO y-ZnPbO3 and Zn2PbO4-similarly synthesized by a simple and economical method and shown to be a promising photocathode (p type semiconductor) and photoanode (n-type semiconductor), respectively. From PEC measurements, the bare ZnPbO3 photocathode achieved a photocurrent density of 0.94 mA/cm2 at 0 V versus reversible hydrogen electrode (RHE), whereas the pristine Zn2PbO4 photoanode delivered a photocurrent density of 0.51 mA/cm2 at 1.23 V versus RHE. By depositing suitable cocatalysts onto the photoelectrodes established above, we also demonstrated unassisted overall PEC water splitting, a rare case, if any, wherein a single material system is compositionally engineered for either of the photoelectrodes. PMID- 29578677 TI - Deterministic Design of Chemistry and Mesostructure in Li-Ion Battery Electrodes. AB - All battery electrodes have complex internal three-dimensional architectures that have traditionally been formed through the random packing of the electrode components. What is now emerging is a new concept in battery electrode design, where the important electronic and ionic pathways, as well as the chemical interactions between the components of the electrode, are deterministically designed. Deterministic design enables far better properties than are possible through random packing, including dramatic improvements in both power and energy. Such a design approach is particularly attractive for emerging high-energy density materials, which require available free volume as they swell during cycling. In addition to controlled structure, another important facet of the design of such systems is the stable chemical linkages between the active material and the conductive network that survive the lithiation and delithiation processes. In this Perspective, we discuss and provide our views on deterministically designed battery electrodes. PMID- 29578678 TI - Band Edge Dynamics and Multiexciton Generation in Narrow Band Gap HgTe Nanocrystals. AB - Mercury chalcogenide nanocrystals and especially HgTe appear as an interesting platform for the design of low cost mid-infrared (mid-IR) detectors. Nevertheless, their electronic structure and transport properties remain poorly understood, and some critical aspects such as the carrier relaxation dynamics at the band edge have been pushed under the rug. Some of the previous reports on dynamics are setup-limited, and all of them have been obtained using photon energy far above the band edge. These observations raise two main questions: (i) what are the carrier dynamics at the band edge and (ii) should we expect some additional effect (multiexciton generation (MEG)) as such narrow band gap materials are excited far above the band edge? To answer these questions, we developed a high-bandwidth setup that allows us to understand and compare the carrier dynamics resonantly pumped at the band edge in the mid-IR and far above the band edge. We demonstrate that fast (>50 MHz) photoresponse can be obtained even in the mid-IR and that MEG is occurring in HgTe nanocrystal arrays with a threshold around 3 times the band edge energy. Furthermore, the photoresponse can be effectively tuned in magnitude and sign using a phototransistor configuration.

Unfortunately, very few studies have been devoted to the preparation of thin films with both antireflective and antibacterial properties. In this study, mesoporous silica (MSiO2) thin films with uniformly dispersed Ag nanoparticles (Ag NPs) were prepared through a one-pot process, which simultaneously shows high transmittance, excellent antibacterial activity, and mechanical robustness. The optimal thin-film-coated glass substrate demonstrates a maximum transmittance of 98.8% and an average transmittance of 97.1%, respectively, in the spectral range of 400-800 nm. The growth and multiplication of typical bacteria, Escherichia coli ( E. coli), were effectively inhibited on the coated glass. Pencil hardness test, tape adhesion test, and sponge washing test showed favorable mechanical robustness with 5H pencil hardness, 5A grade adhesion, and functional durability of the coating, which promises great potential for applications in various touch screens, windows for hygiene environments, and optical apparatuses for medical uses such as endoscope, and so on. PMID- 29578680 TI - Metal Ion/Tannic Acid Assembly as a Versatile Photothermal Platform in Engineering Multimodal Nanotheranostics for Advanced Applications. AB - This study reports a family of photothermal materials, metal ion/tannic acid assemblies (MITAs). MITAs from FeIII, VIII, and RuIII afford excellent photothermal efficiency (eta ~ 40%). Sharply differing from the currently existing photothermal agents, MITAs are highlighted by merits including green synthesis, facile incorporation of diagnostic metal ions, and particularly topology-independent adhesion. Owing to the adhesion nature of MITAs, various kinds of MITA-based nanoengineerings are readily available via the self-adhesion of MITAs onto diverse templates, enabling MITAs well suited as a photothermal platform for versatile combination with other therapy approaches and imaging techniques. As a proof of concept, polymeric/inorganic nanoparticle/nanovesicle supported FeIII-tannic acid (FeIIITA) is fabricated. The photothermal effect is shown to be unaffected by the template origin and type and FeIIITA thickness on the templates. We validate the potency of nanovesicle-supported FeIIITA (PNV@FeIIITA) for tumor-specific photoactivated utilizations, including NIR photothermal therapy with complete tumor elimination, photothermal imaging (PTI), and photoacoustic imaging (PAI) in addition to T1-MRI imaging. PNV@FeIIITA can be simultaneously equipped with functionalities, including T2-MRI imaging by additionally doping MnII and NIR fluorescence imaging by encapsulating a hydrophilic NIR fluoroprobe. MITA demonstrates unparalleled superiority as a photothermal platform in engineering multimodal theranostics for advanced applications. PMID- 29578681 TI - Solid-Phase Synthesis of beta-Hydroxy Ketones Via DNA-Compatible Organocatalytic Aldol Reactions. AB - One-bead one-compound (OBOC) libraries constructed by solid-phase split-and-pool synthesis are a valuable source of protein ligands. Most OBOC libraries are composed of oligoamides, particularly peptides, peptoids, and peptoid-inspired molecules. Further diversification of the chemical space covered by OBOC libraries is desirable. Toward this end, we report here that the proline catalyzed asymmetric aldol reaction, developed by List and Barbas for solution phase synthesis, also works well for coupling immobilized aldehydes and soluble ketones. These reaction conditions do not compromise the amplification of DNA by the polymerase chain reaction. Thus, this chemistry should be useful for the construction of novel DNA-encoded OBOC libraries by solid-phase synthesis. PMID- 29578682 TI - Zeolite-like Metal-Organic Framework (MOF) Encaged Pt(II)-Porphyrin for Anion Selective Sensing. AB - The selectivity and sensitivity of sensors are of great interest to the materials chemistry community, and a lot of effort is now devoted to improving these characteristics. More specifically, the selective sensing of anions is one of the largest challenges impeding the sensing-research area due to their similar physical and chemical behaviors. In this work, platinum-metalated porphyrin (Pt(II)TMPyP) was successfully encapsulated in a rho-type zeolite-like metal organic framework (rho-ZMOF) and applied for anion-selective sensing. The sensing activity and selectivity of the MOF-encaged Pt(II)TMPyP for various anions in aqueous and methanolic media were compared to that of the free (nonencapsulated) Pt(II)TMPyP. While the photoinduced triplet-state electron transfer of Pt(II)TMPyP showed a very low detection limit for anions with no selectivity, the Pt(II)TMPyP encapsulated in the rho-ZMOF framework possessed a unique chemical structure to overcome such limitations. This new approach has the potential for use in other complex sensing applications, including biosensors, which require ion selectivity. PMID- 29578683 TI - Immunohistochemical Approach to Understanding the Organization of the Olfactory System in the Cuttlefish, Sepia officinalis. AB - Cephalopods are nontraditional but captivating models of invertebrate neurobiology, particularly in evolutionary comparisons. Cephalopod olfactory systems have striking similarities and fundamental differences with vertebrates, arthropods, and gastropods, raising questions about the ancestral origins of those systems. We describe here the organization and development of the olfactory system of the common cuttlefish, Sepia officinalis, using immunohistochemistry and in situ hybridization. FMRFamide and/or related peptides and histamine are putative neurotransmitters in olfactory sensory neurons. Other neurotransmitters, including serotonin and APGWamide within the olfactory and other brain lobes, suggest efferent control of olfactory input and/or roles in the processing of olfactory information. The distributions of neurotransmitters, along with staining patterns of phalloidin, anti-acetylated alpha-tubulin, and a synaptotagmin riboprobe, help to clarify the structure of the olfactory lobe. We discuss a key difference, the lack of identifiable olfactory glomeruli, in cuttlefish in comparison to other models, and suggest its implications for the evolution of olfaction. PMID- 29578684 TI - Robust Mesoporous CoMo/gamma-Al2O3 Catalysts from Cyclodextrin-Based Supramolecular Assemblies for Hydrothermal Processing of Microalgae: Effect of the Preparation Method. AB - Hydrothermal liquefaction (HTL) is a promising technology for the production of biocrude oil from microalgae. Although this catalyst-free technology is efficient under high-temperature and high-pressure conditions, the biocrude yield and quality can be further improved by using heterogeneous catalysts. The design of robust catalysts that preserve their performance under hydrothermal conditions will be therefore very important in the development of biorefinery technologies. In this work, we describe two different synthetic routes (i.e., impregnation and cyclodextrin-assisted one-pot colloidal approach), for the preparation in aqueous phase of six high surface area CoMo/gamma-Al2O3 catalysts. Catalytic tests performed on the HTL of Nannochloropsis gaditana microalga indicate that solids prepared by the one-pot colloidal approach show higher hydrothermal stability and enhanced biocrude yield with respect to the catalyst-free test. The positive effect of the substitution of the block copolymer Tetronic T90R4 for Pluronic F127 in the preparation procedure was evidenced by diffuse reflectance UV-visible spectroscopy, X-ray diffraction, N2-adsorption-desorption, and H2-temperature programmed reduction measurements and confirmed by the higher quality of the obtained biocrude, which exhibited lower oxygen content and higher-energy recovery equal to 62.5% of the initial biomass. PMID- 29578685 TI - Inkjet Printing Enabled Controllable Paper Superhydrophobization and Its Applications. AB - Papers' intrinsic interconnected porous structures and hydrophilic properties usually results in difficulty and complexity in partial functionalization and regulation processes because the capillary effect may lead to the fast diffusion of modifiers from one side to the other. Here, we report a simple and innovative inkjet printing approach that led to precise hydrophobic functionalization controllable in both planar and steric dimensions. Fabrication of Janus superwetting papers and superwettable patterned papers with high precision was achieved by computer-controlled inkjet printing. Elaborate controls of ink quantity enabled superhydrophobic functionalization on one side of the paper substrate, with the opposite side superhydrophilic. Static water contact angles up to 154 degrees were obtained on the inkjet-printed side of the paper, thanks to an appropriate combination of surface chemistry with dual-scale surface roughness. Furthermore, paper-based microfluidics were fabricated and the resolution of which were estimated to be ca. 600 MUm. Meanwhile, a paper-based analytical device for colorimetric sensing of Ni(II) was designed and demonstrated based on superwettable patterned papers by inkjet printing. The inkjet printing approach reported here represents a key step forward in fabricating Janus materials and complicate patterns for practical applications. PMID- 29578686 TI - Silicones for Stretchable and Durable Soft Devices: Beyond Sylgard-184. AB - This paper identifies and characterizes silicone elastomers that are well-suited for fabricating highly stretchable and tear-resistant devices that require interfacial bonding by plasma or UV ozone treatment. The ability to bond two or more pieces of molded silicone is important for creating microfluidic channels, chambers for pneumatically driven soft robotics, and other soft and stretchable devices. Sylgard-184 is a popular silicone, particularly for microfluidic applications. However, its low elongation at break (~100% strain) and moderate tear strength (~3 N/mm) make it unsuitable for emerging, mechanically demanding applications of silicone. In contrast, commercial silicones, such as Dragon Skin, have excellent mechanical properties yet are difficult to plasma-bond, likely because of the presence of silicone oils that soften the network yet migrate to the surface and interfere with plasma bonding. We found that extracting silicone oligomers from these soft networks allows these materials to bond but only when the Shore hardness exceeds a value of 15 A. It is also possible to mix highly stretchable silicones (Dragon Skin and Ecoflex) with Sylgard-184 to create silicones with intermediate mechanical properties; interestingly, these blends also only bond when the hardness exceeds 15 A. Eight different Pt-cured silicones were also screened; again, only those with Shore hardness above 15 A plasma-bond. The most promising silicones from this study are Sylgard-186 and Elastosil-M4130 and M4630, which exhibit a large deformation (>200% elongation at break), high tear strength (>12 N/mm), and strong plasma bonding. To illustrate the utility of these silicones, we created stretchable electrodes by injecting a liquid metal into microchannels created using such silicones, which may find use in soft robotics, electronic skin, and stretchable energy storage devices. PMID- 29578687 TI - Esterase-Catalyzed Siderophore Hydrolysis Activates an Enterobactin-Ciprofloxacin Conjugate and Confers Targeted Antibacterial Activity. AB - Enteric Gram-negative bacteria, including Escherichia coli, biosynthesize and deploy the triscatecholate siderophore enterobactin (Ent) in the vertebrate host to acquire iron, an essential nutrient. We report that Ent-Cipro, a synthetic siderophore-antibiotic conjugate based on the native Ent platform that harbors an alkyl linker at one of the catechols with a ciprofloxacin cargo attached, affords targeted antibacterial activity against E. coli strains that express the pathogen associated iroA gene cluster. Attachment of the siderophore to ciprofloxacin, a DNA gyrase inhibitor and broad-spectrum antibiotic that is used to treat infections caused by E. coli, generates an inactive prodrug and guides the antibiotic into the cytoplasm of bacteria that express the Ent uptake machinery (FepABCDG). Intracellular hydrolysis of the siderophore restores the activity of the antibiotic. Remarkably, Fes, the cytoplasmic Ent hydrolase expressed by all E. coli, does not contribute to Ent-Cipro activation. Instead, this processing step requires IroD, a cytoplasmic hydrolase that is expressed only by E. coli that harbor the iroA gene cluster and are predominantly pathogenic. In the uropathogenic E. coli UTI89 and CFT073, Ent-Cipro provides antibacterial activity comparable to unmodified ciprofloxacin. This work highlights the potential of leveraging and targeting pathogen-associated microbial enzymes in narrow-spectrum antibacterial approaches. Moreover, because E. coli include harmless gut commensals as well as resident microbes that can contribute to disease, Ent-Cipro may provide a valuable chemical tool for strain-selective modulation of the microbiota. PMID- 29578689 TI - Ratiometric Fluorescent Biosensor for Visual Discrimination of Cancer Cells with Different Telomerase Expression Levels. AB - Telomerase is inactive in normal somatic cells but highly activated in tumor cells to maintain their indefinite proliferation and immortal phenotype. As a specific marker for the generation and progress of almost all tumors, the detection of telomerase activity by classical PCR techniques has served in the biological research of tumors. However, the detection of in situ telomerase activity in cell extracts to evaluate the malignancy, progress, and metastasis of tumors remains a daunting challenge. Here, a precisely designed FRET-based ratiometric fluorescent oligonucleotide probe has achieved high-fidelity detection of telomerase activity for accurate discrimination of different cancer cells toward advanced diagnosis of tumors. Our method is superior to other methods in its capabilities to quantify telomerase activity in cell extracts and visualize various tumor cell extracts with different telomerase expression levels by the naked eye for clinical diagnosis. In particular, the ratiometric fluorescent probe used in the assay could exclude other experimental factors influence, and further avoid false positive signal generation. The method reported here could provide a reliable, accurate, and convenient way in medical diagnostics and therapeutic response assessment. PMID- 29578688 TI - Unprecedented Role of Hybrid N-Glycans as Ligands for HIV-1 Broadly Neutralizing Antibodies. AB - The development of an HIV vaccine has been hampered by the extraordinary mutability and genetic diversity of the virus, particularly the substantial sequence diversity of gp120 and gp 41 envelope glycoproteins existing in more than 2000 HIV variants. The highly diverse glycans on HIV spikes are commonly considered as immunologically silent self-antigens; however, the discovery of highly potent broadly neutralizing antibodies (bNAbs) from HIV patients targeting the viral surface glycans has raised a major question about the origin of their antigens. Recent epitope mapping studies of the bNAb PG9 indicated a requirement of a properly spaced high mannose and a complex type glycan connected by a short peptide spacer. We have recently discovered that a 1:1 mixture of Man5 and sialyl biantennary glycan with well-defined distance and without the peptide spacer is well recognized by PG9 with high avidity and, thus, proposed that a hybrid glycan with oligomannose and complex-type arm could be the proper ligand of PG9. To verify this proposition, we first designed and chemo-enzymatically synthesized a series of unusual hybrid-type N-glycan structures, which may exist on HIV surface glycoproteins through the host-guided N-glycosylation pathway. The synthetic hybrid glycans were then used to prepare glycan arrays for the binding studies of PG9 and several other highly potent bNAbs, including PG16, PGT121, PGT128-3C, 2G12, VRC13, VRC-PG05, VRC26.25, VRC26.09, PGDM1400, 35O22, and 10-1074. Our results demonstrated that PG9 and some other bNAbs bind with strong avidity (subnanomolar Kd) to certain hybrid structures, suggesting that these unusual glycans may serve as epitopes for the design of vaccines against HIV. PMID- 29578690 TI - Mitochondria-Targeting Peptoids. AB - Mitochondria-specific delivery methods offer a valuable tool for studying mitochondria-related diseases and provide breakthroughs in therapeutic development. Although several small-molecule and peptide-based transporters have been developed, peptoids, proteolysis-resistant peptidomimetics, are a promising alternative to current approaches. We designed a series of amphipathic peptoids and evaluated their cellular uptake and mitochondrial localization. Two peptoids with cyclohexyl residues demonstrated highly efficient cell penetration and mitochondrial localization without significant adverse effects on the cells and mitochondria. These mitochondria-targeting peptoids could facilitate the selective and robust targeted delivery of bioactive compounds, such as drugs, antioxidants, and photosensitizers, with minimal off-target effects. PMID- 29578691 TI - Removal of Arsenic from Strongly Acidic Wastewater Using Phosphorus Pentasulfide As Precipitant: UV-Light Promoted Sulfuration Reaction and Particle Aggregation. AB - Strongly acidic wastewater (H2SO4) with a high arsenic concentration is produced by many industries. The removal of arsenic by traditional sulfide (e.g., Na2S, FeS) from strongly acidic wastewater introduces cations (Na+ and Fe2+) to the solution, which may prevent the recycle of acid. In this study, a new sulfuration agent, phosphorus pentasulfide (P2S5) was employed, and its feasibility in arsenic removal from strongly acidic wastewater was investigated. In the dark, As(III) was efficiently removed, but the removal rate of As(V) was rather slow, which was the crucial defect for this method. We found that this defect can be efficiently overcome by UV irradiation through accelerating the formation and transformation of an intermediate species, monothioarsenate (H3AsO3S) in the As(V) removal process. In addition, the hydrolysis of P2S5 was enhanced under UV irradiation, which resulted in the increase of the arsenic removal efficiencies. Besides, the aggregation of the formed particles was also promoted. Different from FeS and Na2S, P2S5 introduces H3PO4 instead of cations to the solution, which can facilitate the recycle and reuse of arsenic and acid in strongly acidic wastewater. PMID- 29578692 TI - ATP-Linked Chimeric Nucleotide as a Specific Luminescence Reporter of Deoxyuridine Triphosphatase. AB - Nucleotide surveillance enzymes play important roles in human health, by monitoring damaged monomers in the nucleotide pool and deactivating them before they are incorporated into chromosomal DNA or disrupt nucleotide metabolism. In particular, deamination of cytosine, leading to uracil in DNA and in the nucleotide pool, can be deleterious, causing DNA damage. The enzyme deoxyuridine triphosphatase (dUTPase) is currently under study as a therapeutic and prognostic target for cancer. Measuring the activity of this enzyme is important both in basic research and in clinical applications involving this pathway, but current methods are nonselective, detecting pyrophosphate, which is produced by many enzymes. Here we describe the design and synthesis of a dUTPase enzyme-specific chimeric dinucleotide (DUAL) that replaces the pyrophosphate leaving group of the native substrate with ATP, enabling sensitive detection via luciferase luminescence signaling. The DUAL probe functions sensitively and selectively to quantify enzyme activities in vitro and in cell lysates. We further report the first measurements of dUTPase activities in eight different cell lines, which are found to vary by a factor of 7-fold. We expect that the new probe can be of considerable utility in research involving this clinically significant enzyme. PMID- 29578693 TI - Memristive Ion Channel-Doped Biomembranes as Synaptic Mimics. AB - Solid-state neuromorphic systems based on transistors or memristors have yet to achieve the interconnectivity, performance, and energy efficiency of the brain due to excessive noise, undesirable material properties, and nonbiological switching mechanisms. Here we demonstrate that an alamethicin-doped, synthetic biomembrane exhibits memristive behavior, emulates key synaptic functions including paired-pulse facilitation and depression, and enables learning and computing. Unlike state-of-the-art devices, our two-terminal, biomolecular memristor features similar structure (biomembrane), switching mechanism (ion channels), and ionic transport modality as biological synapses while operating at considerably lower power. The reversible and volatile voltage-driven insertion of alamethicin peptides into an insulating lipid bilayer creates conductive pathways that exhibit pinched current-voltage hysteresis at potentials above their insertion threshold. Moreover, the synapse-like dynamic properties of the biomolecular memristor allow for simplified learning circuit implementations. Low power memristive devices based on stimuli-responsive biomolecules represent a major advance toward implementation of full synaptic functionality in neuromorphic hardware. PMID- 29578694 TI - Depth Profiling and Cross-Sectional Laser Ablation Ionization Mass Spectrometry Studies of Through-Silicon-Vias. AB - Through-silicon-via (TSV) technology enables 3D integration of multiple 2D components in advanced microchip architectures. Key in the TSV fabrication is an additive-assisted Cu electroplating process in which the additives employed may get embedded in the TSV body. This incorporation negatively influences the reliability and durability of the Cu interconnects. Here, we present a novel approach toward the chemical analysis of TSVs which is based on femtosecond laser ablation ionization mass spectrometry (fs-LIMS). The conditions for LIMS depth profiling were identified by a systematic variation of the laser pulse energy and the number of laser shots applied. In this contribution, new aspects are addressed related to the analysis of highly heterogeneous specimens having dimensions in the range of the probing beam itself. Particularly challenging were the different chemical and physical properties of which the target specimens were composed. Depth profiling of the TSVs along their main axis (approach 1) revealed a gradient in the carbon (C) content. These differences in the C concentration inside the TSVs could be confirmed and quantified by LIMS analyses of cross sectionally sliced TSVs (approach 2). Our quantitative analysis revealed a C content that is ~1.5 times higher at the TSV top surface compared to its bottom. Complementary Scanning Auger Microscopy (SAM) data confirmed a preferential embedment of suppressor additives at the side walls of the TSV. These results demonstrate that the TSV filling concept significantly deviates from common Damascene electroplating processes and will therefore contribute to a more comprehensive, mechanistic understanding of the underlying mechanisms. PMID- 29578695 TI - A Review of Environmental Occurrence, Fate, Exposure, and Toxicity of Benzothiazoles. AB - Benzothiazole and its derivatives (BTs) are high production volume chemicals that have been used for several decades in a large number of industrial and consumer products, including vulcanization accelerators, corrosion inhibitors, fungicides, herbicides, algicides, and ultraviolet (UV) light stabilizers. Several benzothiazole derivatives are used commercially, and widespread use of these chemicals has led to ubiquitous occurrence in diverse environmental compartments. BTs have been reported to be dermal sensitizers, respiratory tract irritants, endocrine disruptors, carcinogens, and genotoxicants. This article reviews occurrence and fate of a select group of BTs in the environment, as well as human exposure and toxicity. BTs have frequently been found in various environmental matrices at concentrations ranging from sub-ng/L (surface water) to several tens of MUg/g (indoor dust). The use of BTs in a number of consumer products, especially in rubber products, has resulted in widespread human exposure. BTs undergo chemical, biological, and photolytic degradation in the environment, creating several transformation products. Of these, 2-thiocyanomethylthio benzothiazole (2-SCNMeS-BTH) has been shown to be the most toxic. Epidemiological studies have shown excess risks of cancers, including bladder cancer, lung cancer, and leukemia, among rubber factory workers, particularly those exposed to 2-mercapto-benzothiazole (2-SH-BTH). Human exposure to BTs continues to be a concern. PMID- 29578696 TI - Microfluidic Chip with Integrated Electrophoretic Immunoassay for Investigating Cell-Cell Interactions. AB - Microfluidics have been used to create "body-on-chip" systems to mimic in vivo cellular interactions with a high level of control. Most such systems rely on optical observation of cells as a readout. In this work we integrated a cell-cell interaction chip with online microchip electrophoresis immunoassay to monitor the effects of the interaction on protein secretion dynamics. The system was used to investigate the effects of adipocytes on insulin secretion. Chips were loaded with 190 000 3T3-L1 adipocytes and a single islet of Langerhans in separate chambers. The chambers were perfused at 300-600 nL/min so that adipocyte secretions flowed over the islets for 3 h. Adipocytes produced 80 MUM of nonesterified fatty acids (NEFAs), a factor known to impact insulin secretion, at the islets. After perfusion, islets were challenged with a step change in glucose from 3 to 11 mM while monitoring insulin secretion at 8 s intervals by online immunoassay. Adipocyte treatment augmented insulin secretion by 6-fold compared to controls. The effect was far greater than comparable concentrations of NEFA applied to the islets demonstrating that adipocytes release multiple factors that can strongly potentiate insulin secretion. The experiments reveal that integration of chemical analysis with cell-cell interaction can provide valuable insights into cellular functions. PMID- 29578697 TI - Coencapsulation of (-)-Epigallocatechin-3-gallate and Quercetin in Particle Stabilized W/O/W Emulsion Gels: Controlled Release and Bioaccessibility. AB - Particle-stabilized W1/O/W2 emulsion gels were fabricated using a two-step procedure: ( i) a W1/O emulsion was formed containing saccharose (for osmotic stress balance) and gelatin (as a gelling agent) in the aqueous phase and polyglycerol polyricinoleate (a lipophilic surfactant) in the oil phase; ( ii) this W1/O emulsion was then homogenized with another water phase (W2) containing wheat gliadin nanoparticles (hydrophilic emulsifier). The gliadin nanoparticles in the external aqueous phase aggregated at pH 5.5, which led to the formation of particle-stabilized W1/O/W2 emulsion gels with good stability to phase separation. These emulsion gels were then used to coencapsulate a hydrophilic bioactive (epigallocatechin-3-gallate, EGCG) in the internal aqueous phase (encapsulation efficiency = 65.5%) and a hydrophobic bioactive (quercetin) in the oil phase (encapsulation efficiency = 97.2%). The emulsion gels improved EGCG chemical stability and quercetin solubility under simulated gastrointestinal conditions, which led to a 2- and 4-fold increase in their effective bioaccessibility, respectively. PMID- 29578698 TI - Enhanced Visible-Light-Driven Photocatalytic Bacterial Inactivation by Ultrathin Carbon-Coated Magnetic Cobalt Ferrite Nanoparticles. AB - Ultrathin hydrothermal carbonation carbon (HTCC)-coated cobalt ferrite (CoFe2O4) composites with HTCC coating thicknesses between 0.62 and 4.38 nm were fabricated as novel, efficient, and magnetically recyclable photocatalysts via a facile, green approach. The CoFe2O4/HTCC composites showed high magnetization and low coercivity, which favored magnetic separation for reuse. The results show that the close coating of HTCC on CoFe2O4 nanoparticles enhanced electron transfer and charge separation, leading to a significant improvement in photocatalytic efficiency. The composites exhibited superior photocatalytic inactivation toward Escherichia coli K-12 under visible-light irradiation, with the complete inactivation of 7 log10 cfu.mL-1 of bacterial cells within 60 min. The destruction of bacterial cell membranes was monitored by field-effect scanning electron microscopy analysis and fluorescence microscopic images. The bacterial inactivation mechanism was investigated in a scavenger study, and *O2, H2O2, and h+ were identified as the major reactive species for bacterial inactivation. Multiple cycle runs revealed that these composites had excellent stability and reusability. In addition, the composites showed good photocatalytic bacterial inactivation performance in authentic water matrices such as surface water samples and secondarily treated sewage effluents. The results of this work indicate that CoFe2O4/HTCC composites have great potential in large-scale photocatalytic disinfection operations.

AB - The methyl groups of [ methyl-( S)]- and [ methyl-( R)]-[ methyl-D,T]-l methionine fed to Streptomyces fradiae were incorporated into fosfomycin, which was chemically degraded to chiral AcONa. The enzymatic test gave the ( S) configuration for the chiral AcONa derived from methionine with the ( S) [D,T]methyl group ( F = 31.7) and ( R) for the one derived from methionine with the ( R)-[D,T]methyl group ( F = 83.0).

PMID- 29578700 TI - Revisiting the Mechanism of Oxidative Unzipping of Multiwall Carbon Nanotubes to Graphene Nanoribbons. AB - Unzipping multiwall carbon nanotubes (MWCNTs) attracted great interest as a method for producing graphene nanoribbons (GNRs). However, depending on the production method, the GNRs have been proposed to form by different mechanisms. Here, we demonstrate that the oxidative unzipping of MWCNTs is intercalation driven, not oxidative chemical-bond cleavage as was formerly proposed. The unzipping mechanism involves three consecutive steps: intercalation-unzipping, oxidation, and exfoliation. The reaction can be terminated at any of these three steps. We demonstrate that even in highly oxidative media one can obtain nonoxidized GNR products. The understanding of the actual unzipping mechanism lets us produce GNRs with hybrid properties varying from nonoxidized through heavily oxidized materials. We answer several questions such as the reason for the innermost walls of the nanotubes remaining zipped. The intercalation-driven reaction mechanism provides a rationale for the difficulty in unzipping single wall and few-wall CNTs and aids in a reevaluation of the data from the oxidative unzipping process. PMID- 29578701 TI - Chemical Transformations in Confined Space of Coordination Architectures. AB - The scholastic significance of supramolecular chemistry continues to grow with the recent development of catalytic transformations in confined space of supramolecular architectures. It has come a long way from a natural cavity containing molecules to modern smart materials capable of manipulating reaction pathways. The rise of self-assembled coordination complexes provided a diverse array of host structures. Starting from purely organic compounds to metalloligand surrogates, supramolecular host cavities were tuned according to the requirement of the reactions. The understanding of their participation in a reaction led to better usage of those assemblies for specific reaction sequences. Commencing from cyclodextrin, a wide range of organic molecules was used for cage-catalyzed organic transformations. However, difficulties in synthesis and a tedious purification procedure led chemists to choose a different pathway of metal-ligand coordination-driven self-assembly. The latter stood out as a potential replacement of the organic cages, overcoming the previous drawbacks. In the glut of different transition-metal assemblies used for catalytic transformations, many of them showed chemo- and stereoselective products. However, the small cavity size in some of them led to premature failure of the reaction. In that context, "molecular barrels" showed good efficacy for the catalytic reaction sequence. The large cavity size and bigger orifice for intake of the substrate and easy release of the product made them a better choice for catalysis. Additionally these are mostly used in aqueous media, which reinforces the idea of green and environmentally nonhazardous chemistry. In this Viewpoint, we discuss the use of metal-ligand coordination-driven self-assembled molecular containers used for catalysis with special emphasis on molecular barrels. This paper built on existing literature provides a thorough development of the fertile ground of the coordination architecture for catalysis and its future direction of propagation. PMID- 29578702 TI - Faster Protocol for Endogenous Fatty Acid Esters of Hydroxy Fatty Acid (FAHFA) Measurements. AB - Fatty acid esters of hydroxy fatty acids (FAHFAs) are a recently discovered class of endogenous lipids with antidiabetic and anti-inflammatory activities. Interest in these lipids is due to their unique biological activites and the observation that insulin-resistant people have lower palmitic acid esters of hydroxystearic acid (PAHSA) levels, suggesting that a FAHFA deficiency may contribute to metabolic disease. Rigorous testing of this hypothesis will require the measurement of many clinical samples; however, current analytical workflows are too slow to enable samples to be analyzed quickly. Here we describe the development of a significantly faster workflow to measure FAHFAs that optimizes the fractionation and chromatography of these lipids. We can measure FAHFAs in 30 min with this new protocol versus 90 min using the older protocol with comparable performance in regioisomer detection and quantitation. We also discovered through this optimization that oleic acid esters of hydroxystearic acids (OAHSAs), another family of FAHFAs, have a much lower background signal than PAHSAs, which makes them easier to measure. Our faster workflow was able to quantify changes in PAHSAs and OAHSAs in mouse tissues and human plasma, highlighting the potential of this protocol for basic and clinical applications. PMID- 29578703 TI - Electron Injection from Photoexcited Metal-Organic Framework Ligands to Ru2 Secondary Building Units for Visible-Light-Driven Hydrogen Evolution. AB - We report the design of two new metal-organic frameworks (MOFs), Ru-TBP and Ru TBP-Zn, based on Ru2 secondary building units (SBUs) and porphyrin-derived tetracarboxylate ligands. The proximity of Ru2 SBUs to porphyrin ligands (~1.1 nm) facilitates multielectron transfer from excited porphyrins to Ru2 SBUs to enable efficient visible-light-driven hydrogen evolution reaction (HER) in neutral water. Photophysical and electrochemical studies revealed oxidative quenching of excited porphyrin by Ru2 SBUs as the initial step of the HER process and the energetics of key intermediates in the catalytic cycle. Our work provides a new strategy to building multifunctional MOFs with synergistic ligands and SBUs for efficient photocatalysis. PMID- 29578704 TI - Complete Mechanism of Hemithioindigo Motor Rotation. AB - Hemithioindigo-based molecular motors are powered by nondamaging visible light and provide very fast directional rotations at ambient conditions. Their ground state energy profile has been probed in detail, but the crucial excited state processes are completely unknown so far. In addition, very fast processes in the ground state are also still elusive to date and thus knowledge of the whole operational mechanism remains to a large extent in the dark. In this work we elucidate the complete light-driven rotation mechanism by a combination of multiscale broadband transient absorption measurements covering a time scale from fs to ms in conjunction with a high level theoretical description of the excited state. In addition to a full description of the excited state dynamics in the various time regimes, we also provide the first experimental evidence for the elusive fourth intermediate ground state of the original HTI motor. The fate of this intermediate also is followed directly proving complete unidirectionality for both 180 degrees rotation steps. At the same time, we uncover the hitherto unknown involvement of an unproductive triplet state pathway, which slightly diminishes the quantum yield of the E to Z photoisomerization. A rate model analysis shows that increasing the speed of motor rotation is most effectively done by increasing the photoisomerization quantum yields instead of barrier reduction for the thermal ratcheting steps. Our findings are of crucial importance for improved future designs of any light-driven molecular motor in general to yield better efficiencies and applicability.

AB - : Fragment-based methods promise accurate energetics at a cost that scales linearly with the number of fragments. This promise is founded on the premise that the many-body expansion (or another similar energy decomposition) needs to only consider spatially local many-body interactions. Experience and chemical intuition suggest that typically at most four-body interactions are required for high accuracy. Bettens and co-workers [ J. Chem. Theory Comput. 2014 9, 3699 3707] published a detailed study showing that for moderately sized water clusters, basis set superposition error (BSSE) undermines this premise. Ultimately, they were able to overcome BSSE by performing all computations in the supersystem basis set, but such a solution destroys the reduced computational scaling of fragment-based methods. Their findings led them to suggest that there is "trouble with the many-body expansion". Since then, a subsequent follow-up study from Bettens and co-workers [ J. Chem. THEORY: Comput. 2015, 11, 5132-5143] as well as a related study by Mayer and Bako [ J. Chem. Theory Comput. 2017, 13, 1883-1886] have proposed new frameworks for understanding BSSE in the many-body expansion. Although the two frameworks ultimately propose the same working set of equations to the BSSE problem, their interpretations are quite different, even disagreeing on whether or not the solution is an approximation. In this work we propose a more general BSSE framework. We then show that, somewhat paradoxically, the two interpretations are compatible and amount to two different "normalization" conditions. Finally, we consider applications of these BSSE frameworks to small water clusters, where we focus on replicating high-accuracy coupled cluster benchmarks. Ultimately, we show for water clusters, using the present framework, that one can obtain results that are within +/-0.5 kcal mol-1 of the coupled cluster complete basis set limit without considering anymore than a correlated three-body computation in a quadruple-zeta basis set and a four-body triple-zeta Hartree-Fock computation.

AB - An artificial metabolic route to an unnatural trichothecene was designed by taking advantage of the broad substrate specificities of the T-2 toxin biosynthetic enzymes of Fusarium sporotrichioides. By feeding 7 hydroxyisotrichodermin, a shunt pathway metabolite of F. graminearum, to a trichodiene synthase-deficient mutant of F. sporotrichioides, 7-hydroxy T-2 toxin (1) was obtained as the final metabolite. Such an approach may have future applications in the metabolic engineering of a variety of fungal secondary metabolites. The toxicity of 7-hydroxy T-2 toxin was 10 times lower than that of T-2 toxin in HL-60 cells.

AB - Carboxyl-enriched and size-selected polymer nanoparticles (NPs) may prove to be very useful in biomedical applications for linker-free binding of biomolecules and their transport to cells. In this study, we report about the synthesis of such NPs by low-pressure low-temperature pulsed plasma polymerization of acrylic acid. Gas aggregation cluster source was adapted to operate plasma with a constant pulse period of 50 MUs and with varying duty cycle. The NPs were produced with the size ranging from 31 +/- 5 to 93 +/- 14 nm and with retention of the carboxyl groups ranging from 4.0 to 12.0 atom %. Two regimes of the NP formation were identified. In the large duty cycle regime, the NP growth was interfered with by positive ion bombardment which resulted in the ion-driven detachment of the carboxyl species and in the formation of carboxyl-deficient NPs. In the small duty cycle regime, the NP growth was accompanied by the radical driven chain propagation with the attachment of intact monomer molecules. Improved efficacy of the monomer retention resulted in increased concentration of the carboxyl groups.

AB - Although Lysobacter species are a remarkable source of natural compounds with antibacterial and antifungal activities, the ability of these bacteria to produce plant growth promoters remains practically unknown. In this work, the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) has been isolated from the secretions of Lysobacter gummosus OH17, indicating the presence of an ACC deaminase, which was shown to be encoded in the gene peg_1256. The recombinant enzyme could not only deaminate ACC to provide 2-oxobutanoic acid but also catalyzed the amination of the 2-oxobutanoic acid, demonstrating, for the first time, that ACC deaminases can produce ACC. After the treatment of rice Oryza sativa Nipponbare plants with OH17 ACC deaminase, the ethylene production levels were 44% higher in comparison with the control experiments, allowing significant improvements in root, 10%, and stem, 14%, growth. PMID- 29578709 TI - Conformational Preference Determined by C-H...pi Interaction of an O-H...O Hydrogen-Bonded Binary Complex of p-Fluorophenol with 2,5-Dihydrofuran: A Laser Induced Fluorescence Spectroscopy Study. AB - Conformational preferences of a binary hydrogen-bonded complex between p fluorophenol (pFP) and 2,5-dihydrofuran (DHF) have been studied by means of laser induced fluorescence (LIF) spectroscopy in a supersonic jet expansion. Calculation predicts two major conformers for this complex, one having a nearly linear geometry in which the two molecular moieties are bound only by an O-H...O H-bond, but in the other an additional C-H...pi type interaction between an ortho C-H group of pFP and ethylene group of DHF contributes to the binding stabilization and results in a folded geometry for the complex with respect to a global view, although the H-bond angle of the latter is relatively larger. This prediction is realized experimentally by identifying transitions corresponding to the two discrete conformers in a vibrationally resolved LIF excitation spectrum of the complex, and the red shifts of S1-S0 origin band of pFP moiety of the two conformers are 542 and 659 cm-1, respectively. The assignments are corroborated by means of dispersed fluorescence (DF) spectroscopy. In comparison, the LIF spectral bands for the pFP-tetrahydrofuran complex can be corresponded to only one conformer, whose S1-S0 origin transition shows a red shift (563 cm-1) somewhat similar to the linear conformer of pFP-DHF complex. Such similarities in spectral shifting behavior is consistent with the predictions of electronic structure calculations. The DF spectra also reveal that the energy threshold and pathways of vibrational dynamics in S1 of the two conformers show different behavior. Excitation to 6a1 level of pFP moiety of the folded conformer displays signatures of restricted intramolecular vibrational energy redistribution (IVR), whereas the linear form displays the emission feature for dissipative IVR. PMID- 29578710 TI - Chemogenomic Profiling of Human and Microbial FK506-Binding Proteins. AB - FK506-binding proteins (FKBPs) are evolutionarily conserved proteins that display peptidyl-prolyl isomerase activities and act as coreceptors for immunosuppressants. Microbial macrophage-infectivity-potentiator (Mip)-type FKBPs can enhance infectivity. However, developing druglike ligands for FKBPs or Mips has proven difficult, and many FKBPs and Mips still lack biologically useful ligands. To explore the scope and potential of C5-substituted [4.3.1]-aza bicyclic sulfonamides as a broadly applicable class of FKBP inhibitors, we developed a new synthesis method for the bicyclic core scaffold and used it to prepare an FKBP- and Mip-focused library. This allowed us to perform a systematic structure-activity-relationship analysis across key human FKBPs and microbial Mips, yielding highly improved inhibitors for all the FKBPs studied. A cocrystal structure confirmed the molecular-binding mode of the core structure and explained the affinity gained as a result of the preferred substituents. The best FKBP and Mip ligands showed promising antimalarial, antileginonellal, and antichlamydial properties in cellular models of infectivity, suggesting that substituted [4.3.1]-aza-bicyclic sulfonamides could be a novel class of anti infectives. PMID- 29578711 TI - Breakdown of the Simple Arrhenius Law in the Normal Liquid State. AB - It is common practice to discuss the temperature effect on molecular dynamics of glass formers above the melting temperature in terms of the Arrhenius law. Using dielectric spectroscopy measurements of dc conductivity and structural relaxation time on the example of the typical glass former propylene carbonate, we provide experimental evidence that this practice is not justified. Our conclusions are supported by employing thermodynamic density scaling and the occurrence of inflection points in isothermal dynamic data measured at elevated pressure. Additionally, we propose a more suitable approach to describe the dynamics both above and below the inflection point based on a modified MYEGA model.

AB - Studying the elementary reactions of single-noble-metal-atom-doped species can give theoretical guidance for the design of related single-atom catalysis. Using a combination of mass spectrometry and density functional theory calculations, the reaction of RhAl2O4- with the most stable alkane molecule CH4 under thermal conditions has been studied. The methane tends to be converted into syngas (free H2 and adsorbed CO) with activation of four C-H bonds. In sharp contrast, formaldehyde was generated in the previously reported reaction of PtAl2O4- with CH4. Density functional theory calculations show that the difference in reactivity between RhAl2O4- and PtAl2O4- is found to be due to a higher energy barrier of the third C-H bond activation for the Pt analogue. This work provides the first comparative study on the reactivity of single noble-metal atoms (Rh, Pt) on the same cluster support (Al2O4-) and can be helpful for rational design of single-atom catalysts for selective methane conversion. PMID- 29578713 TI - The Effects of the Interplay between Motor and Brownian Forces on the Rheology of Active Gels. AB - Active gels perform key mechanical roles inside the cell, such as cell division, motion, and force sensing. The unique mechanical properties required to perform such functions arise from the interactions between molecular motors and semiflexible polymeric filaments. Molecular motors can convert the energy released in the hydrolysis of ATP into forces of up to piconewton magnitudes. Moreover, the polymeric filaments that form active gels are flexible enough to respond to Brownian forces but also stiff enough to support the large tensions induced by the motor-generated forces. Brownian forces are expected to have a significant effect especially at motor activities at which stable noncontractile in vitro active gels are prepared for rheological measurements. Here, a microscopic mean-field theory of active gels originally formulated in the limit of motor-dominated dynamics is extended to include Brownian forces. In the model presented here, Brownian forces are included accurately, at real room temperature, even in systems with high motor activity. It is shown that a subtle interplay, or competition, between motor-generated forces and Brownian forces has an important impact on the mass transport and rheological properties of active gels. The model predictions show that at low frequencies the dynamic modulus of active gels is determined mostly by motor protein dynamics. However, Brownian forces significantly increase the breadth of the relaxation spectrum and can affect the shape of the dynamic modulus over a wide frequency range even for ratios of motor to Brownian forces of more than a hundred. Since the ratio between motor and Brownian forces is sensitive to ATP concentration, the results presented here shed some light on how the transient mechanical response of active gels changes with varying ATP concentration. PMID- 29578714 TI - Easily Accessible Protein Nanostructures via Enzyme Mediated Addressing. AB - Site-specific formation of nanoscaled protein structures is a challenging task. Most known structuring methods are either complex and hardly upscalable or do not apply to biological matter at all. The presented combination of enzyme mediated autodeposition and nanosphere lithography provides an easy-to-apply approach for the buildup of protein nanostructures over a large scale. The key factor is the tethering of enzyme to the support in designated areas. Those areas are provided via prepatterning of enzymatically active antidots with variable diameters. Enzymatically triggered protein addressing occurs exclusively at the intended areas and continues until the entire active area is coated. After this, the reaction self-terminates. The major advantage of the presented method lies in its easy applicability and upscalability. Large-area structuring of entire support surfaces with features on the nanometer scale is performed efficiently and without the necessity of harsh conditions. These are valuable premises for large scale applications with potentials in biosensor technology, nanoelectronics, and life sciences. PMID- 29578715 TI - Enhanced Global Post-translational Modification Discovery with MetaMorpheus. AB - Correct identification of protein post-translational modifications (PTMs) is crucial to understanding many aspects of protein function in biological processes. G-PTM-D is a recently developed technique for global identification and localization of PTMs. Spectral file calibration prior to applying G-PTM-D, and algorithmic enhancements in the peptide database search significantly increase the accuracy, speed, and scope of PTM identification. We enhance G-PTM-D by using multinotch searches and demonstrate its effectiveness in identification of numerous types of PTMs including high-mass modifications such as glycosylations. The changes described in this work lead to a 20% increase in the number of identified modifications and an order of magnitude decrease in search time. The complete workflow is implemented in MetaMorpheus, a software tool that integrates the database search procedure, identification of coisolated peptides, spectral calibration, and the enhanced G-PTM-D workflow. Multinotch searches are also shown to be useful in contexts other than G-PTM-D by producing superior results when used instead of standard narrow-window and open database searches.

PMID- 29578717 TI - Superior Sensitivity of Copper-Based Plasmonic Biosensors. AB - Plasmonic biosensing has been demonstrated to be a powerful technique for quantitative determination of molecular analytes and kinetic analysis of biochemical reactions. However, interfaces of most plasmonic biosensors are made of noble metals, such as gold and silver, which are not compatible with industrial production technologies. This greatly limits biosensing applications beyond biochemical and pharmaceutical research. Here, we propose and investigate copper-based biosensor chips fully fabricated with a standard complementary metal oxide-semiconductor (CMOS) process. The protection of thin copper films from oxidation is achieved with SiO2 and Al2O3 dielectric films deposited onto the metal surface. In addition, the deposition of dielectric films with thicknesses of only several tens of nanometers significantly improves the biosensing sensitivity, owing to better localization of electromagnetic field above the biosensing surface. According to surface plasmon resonance (SPR) measurements, the copper biosensor chips coated with thin films of SiO2 (25 nm) and Al2O3 (15 nm) show 55% and 75% higher sensitivity to refractive index changes, respectively, in comparison to pure gold sensor chips. To test biomolecule immobilization, the copper-dielectric biosensor chips are coated with graphene oxide linking layers and used for the selective analysis of oligonucleotide hybridization. The proposed plasmonic biosensors make SPR technology more affordable for various applications and provide the basis for compact biosensors integrated with modern electronic devices.

The application of the process has been demonstrated for the synthesis of the circumdatin class of alkaloids in high enantiopurity with retention of the configuration.

PMID- 29578722 TI - Anisotropic-Strain-Induced Band Gap Engineering in Nanowire-Based Quantum Dots. AB - Tuning light emission in bulk and quantum structures by strain constitutes a complementary method to engineer functional properties of semiconductors. Here, we demonstrate the tuning of light emission of GaAs nanowires and their quantum dots up to 115 meV by applying strain through an oxide envelope. We prove that the strain is highly anisotropic and clearly results in a component along the NW longitudinal axis, showing good agreement with the equations of uniaxial stress. We further demonstrate that the strain strongly depends on the oxide thickness, the oxide intrinsic strain, and the oxide microstructure. We also show that ensemble measurements are fully consistent with characterizations at the single NW level, further elucidating the general character of the findings. This work provides the basic elements for strain-induced band gap engineering and opens new avenues in applications where a band-edge shift is necessary. PMID- 29578723 TI - Ga-Doped Pt-Ni Octahedral Nanoparticles as a Highly Active and Durable Electrocatalyst for Oxygen Reduction Reaction. AB - Bimetallic PtNi nanoparticles have been considered as a promising electrocatalyst for oxygen reduction reaction (ORR) in polymer electrolyte membrane fuel cells (PEMFCs) owing to their high catalytic activity. However, under typical fuel cell operating conditions, Ni atoms easily dissolve into the electrolyte, resulting in degradation of the catalyst and the membrane-electrode assembly (MEA). Here, we report gallium-doped PtNi octahedral nanoparticles on a carbon support (Ga PtNi/C). The Ga-PtNi/C shows high ORR activity, marking an 11.7-fold improvement in the mass activity (1.24 A mgPt-1) and a 17.3-fold improvement in the specific activity (2.53 mA cm-2) compared to the commercial Pt/C (0.106 A mgPt-1 and 0.146 mA cm-2). Density functional theory calculations demonstrate that addition of Ga to octahedral PtNi can cause an increase in the oxygen intermediate binding energy, leading to the enhanced catalytic activity toward ORR. In a voltage cycling test, the Ga-PtNi/C exhibits superior stability to PtNi/C and the commercial Pt/C, maintaining the initial Ni concentration and octahedral shape of the nanoparticles. Single cell using the Ga-PtNi/C exhibits higher initial performance and durability than those using the PtNi/C and the commercial Pt/C. The majority of the Ga-PtNi nanoparticles well maintain the octahedral shape without agglomeration after the single cell durability test (30,000 cycles). This work demonstrates that the octahedral Ga-PtNi/C can be utilized as a highly active and durable ORR catalyst in practical fuel cell applications.

PMID- 29578727 TI - Excitons in Core-Shell Nanowires with Polygonal Cross Sections. AB - The distinctive prismatic geometry of semiconductor core-shell nanowires leads to complex localization patterns of carriers. Here, we describe the formation of optically active in-gap excitonic states induced by the interplay between localization of carriers in the corners and their mutual Coulomb interaction. To compute the energy spectra and configurations of excitons created in the conductive shell, we use a multielectron numerical approach based on the exact solution of the multiparticle Hamiltonian for electrons in the valence and conduction bands, which includes the Coulomb interaction in a nonperturbative manner. We expose the formation of well-separated quasidegenerate levels, and focus on the implications of the electron localization in the corners or on the sides of triangular, square, and hexagonal cross sections. We obtain excitonic in gap states associated with symmetrically distributed electrons in the spin singlet configuration. They acquire large contributions due to Coulomb interaction, and thus are shifted to much higher energies than other states corresponding to the conduction electron and the vacancy localized in the same corner. We compare the results of the multielectron method with those of an electron-hole model, and we show that the latter does not reproduce the singlet excitonic states. We also obtain the exciton lifetime and explain selection rules which govern the recombination process. PMID- 29578728 TI - Diels-Alder Reactions with Ethylene and Superelectrophiles. AB - Diels-Alder reactions have been accomplished with ethylene as the dienophile through the use of inverse-electron demand Diels-Alder chemistry. As a key aspect of the chemistry, the dienes are part of tri- or dicationic superelectrophilic systems. Theoretical calculations reveal that the highly charged superelectrophiles possess exceptionally low lying LUMOs, and this facilitates the cycloaddition chemistry with ethylene. The chemistry has been used to prepare a series of tetrahydroquinoline products. This represents the first application of superelectrophilic activation in a cycloaddition reaction, and a new method of utilizing ethylene as a C2 building block. PMID- 29578729 TI - Mental health disorders and mental health problems, active component,U.S. Armed Forces, 2007-2016. AB - Mental health disorders have historically accounted for significant morbidity, healthcare utilization, disability, and attrition from military service. From 2007 through 2016, a total of 853,060 active component service members were diagnosed with at least one mental health disorder and 115,378 were diagnosed with mental health problems related to family/support group problems, maltreatment, lifestyle problems, or substance abuse counseling. Annual incidence rates of at least one mental health disorder decreased by approximately 6.2% during the period. Most of the incident mental health disorder diagnoses were attributable to adjustment disorders, depressive disorders, and anxiety disorders. Similar to the findings of a previous MSMR report, rates of incident mental health disorders were generally higher among females and Army members, and declined with increasing age. The number of individuals affected by any mental health diagnosis during deployment to a U.S. Central Command area of responsibility decreased from 10,951 in 2008 to 3,239 in 2016. Ongoing efforts to assist and treat service members should continue to promote help-seeking behavior to improve psychological and emotional well-being of service members and reduce the burden of mental health disorders. PMID- 29578730 TI - Incidence rates of diagnoses of cardiovascular diseases and associated risk factors, active component, U.S. Armed Forces, 2007-2016. AB - During 2007-2016, 18.1% of all active component service members were diagnosed with at least one of the five risk factors for cardiovascular disease (CVD) studied in this analysis. In addition, 0.6% of service members were diagnosed with at least one of the four CVDs studied. The most frequently diagnosed risk factors were (in descending order of frequency) obesity, hyperlipidemia, essential hypertension, abnormal blood glucose level, and diabetes mellitus. Incidence rates of both risk factors and CVD were progressively higher with advancing age. Annual incidence rates during the 10-year period declined for the risk factors hyperlipidemia, hypertension, and diabetes, but rose for obesity and abnormal blood glucose level. Annual rates of the CVDs ischemic heart disease and cerebrovascular disease declined, but rates of hypertensive heart/kidney disease and atherosclerosis remained relatively stable. Noteworthy findings were the increase in incidence rates of obesity, the decline in incidence rates of ischemic heart disease, and the decline in rates of hypertension in non-Hispanic black service members. The identification of CVD risk factors, including others not studied in this analysis, offers the opportunity for preventive interventions that can reduce the rates of clinical CVD during, but especially after, military service. PMID- 29578731 TI - Herpes zoster, active component, U.S. Armed Forces, 2000-2016. AB - During 2000-2016, a total of 52,895 active component service members received incident diagnoses of herpes zoster (HZ), for an overall unadjusted incidence rate of 2.5 cases per 1,000 person-years (p-yrs). Compared to their respective counterparts, overall incidence rates of HZ were highest among females, those aged 50 years or older, and Air Force members. Overall rates generally increased with increasing age and were highest among non-Hispanic whites and Asian/Pacific Islanders and lowest among non-Hispanic blacks. Unadjusted annual incidence rates of HZ increased steadily from 2000 to a peak in 2014. From 2000 through 2016, annual rates of HZ increased in each service and increases in annual rates were seen in all race/ethnicity groups. Individuals who were identified as immunocompromised constituted 2.1% of the total incident HZ cases. During 2000 2016, the cumulative numbers of incident cases of HZ were highest during June, July, and August. The increase in HZ incidence observed in this and many other studies is a public health concern that requires a better understanding of key risk factors. Additional research focused on these factors could make trends more interpretable, suggest new approaches for prevention and treatment of HZ, and allow for better targeting of existing strategies. PMID- 29578732 TI - Beer for "brohood": A laboratory simulation of masculinity confirmation through alcohol use behaviors in men. AB - Though alcohol use is a widespread behavior, men tend to drink more and experience more alcohol-related negative consequences than do women. Research suggests that individuals are motivated to maintain ingroup status by engaging in behaviors prototypical of the ingroup when group status has been threatened, and that men are particularly likely to do this when masculine ingroup status is threatened. The present study investigated masculine drinking behaviors through a social lens, examining the impact of masculinity threat on alcohol consumption in a simulated bar laboratory. Sixty-five male students ages 21-29 years (Mage = 22.66; 74% White) consumed beer in a taste-test paradigm after being exposed to randomly assigned personality feedback relative to gender standards. This feedback suggested that they were either low in masculinity (threat condition, n = 22) or high in masculinity (control condition, n = 22). A third condition received the low-masculinity feedback and then were exposed to information to undermine masculine alcohol use norms (undermine condition, n = 21) to account for negative affect reduction motives for use. As hypothesized, individuals in the threat condition consumed significantly more alcohol than those in the control and undermine conditions, even though the threat and undermine conditions reported similar levels of negative affect following masculinity threat. These results suggest that consumption of alcohol by men in social contexts may be strongly motivated by the desire to confirm masculine status. This understanding may be used to enhance the effectiveness of alcohol use intervention protocols. (PsycINFO Database Record PMID- 29578733 TI - If you're high status and you know it: Teasing apart the within- and between person effects of peer- and self-reported status in the drinking group on alcohol related outcomes. AB - In this longitudinal study, we disentangled within- and between-persons effects in the relationship between university students' status in their drinking group and alcohol-related behavior. We further examined the role of self-perceived and peer-reported status, with the hypothesis that only when students' peers reported them as of a higher status, and they were aware of their high status (via self report), would they experience increased heavy episodic drinking (HED). University students (N = 118; Mage = 19.40, SD = 1.49; 60.2% women) were recruited in their natural drinking groups (N = 27). All group members completed surveys at 3 time points during the school year, each 2 months apart. We fitted a taxonomy of multilevel growth curve models predicting students' self-reported HED and the extent to which they encouraged other group members to consume alcohol (peer-reported). Between-persons results demonstrated that students who reported higher status compared to their group members experienced more HED on average and students who were peer-reported as of a higher status relative to their group members played a more salient role in encouraging others to drink. Notably, and consistent with hypotheses, a within-person interaction revealed that at time points when students were higher in peer-reported status relative to their average, and they were aware of their increase in status (via self-reports), they also engaged in more HED. Results emphasize the importance of considering within person effects and highlight the need for university alcohol-prevention programming to focus on students' status-related motives and concerns. (PsycINFO Database Record PMID- 29578734 TI - Investigating the incremental validity of cognitive variables in early mathematics screening. AB - The purpose of this study was to investigate the incremental validity of a set of domain general cognitive measures added to a traditional screening battery of early numeracy measures. The sample consisted of 458 kindergarten students of whom 285 were designated as severely at-risk for mathematics difficulty. Hierarchical multiple regression results indicated that Wechsler Abbreviated Scales of Intelligence (WASI) Matrix Reasoning and Vocabulary subtests, and Digit Span Forward and Backward measures explained a small, but unique portion of the variance in kindergarten students' mathematics performance on the Test of Early Mathematics Ability-Third Edition (TEMA-3) when controlling for Early Numeracy Curriculum Based Measurement (EN-CBM) screening measures (R2 change = .01). Furthermore, the incremental validity of the domain general cognitive measures was relatively stronger for the severely at-risk sample. We discuss results from the study in light of instructional decision-making and note the findings do not justify adding domain general cognitive assessments to mathematics screening batteries. (PsycINFO Database Record PMID- 29578735 TI - Establishing individual differences in perceptual capacity. AB - Limited capacity for visual perception results in various "inattentional blindness" phenomena across a wide variety of manipulations that load perception. Here, we propose that these phenomena are mediated by an underlying generalized capacity for visual perception, which also underlies subitizing: the ability to enumerate a limited number of items in parallel from a brief exposure. We tested this proposal by examining whether individual differences reveal common intraindividual variance between measures of visual perception as well as of subitizing capacity. Visual perception was measured in change blindness (Rensink, O'Regan, & Clark, 1997), load-induced blindness (Macdonald & Lavie, 2008), and multiple object tracking tasks. Subitizing capacity was measured as the number of items that could be reported in parallel in an enumeration task. Perceptual capacity as indexed by subitizing was consistently a unique predictor of performance in change blindness, load-induced blindness, and motion tracking beyond any general factors that apply to both subitizing and estimation of larger set sizes. Moreover, when measures of working memory were included, factor analysis indicated two orthogonal factors: perceptual and working memory. Overall, the results support the hypothesis of a generalized capacity for visual perception, and establish subitizing capacity as a predictor of individual susceptibility to inattentional blindness under load. (PsycINFO Database Record PMID- 29578736 TI - Part-list cuing can impair, improve, or not influence recall performance: The critical roles of encoding and access to study context at test. AB - The results of four experiments are reported, in which we examined how the effects of part-list cuing - the presentation of a random selection of studied items as retrieval cues at test - on recall of the remaining target items depend on encoding and access to study context at test. Encoding was varied by inducing high and low degrees of interitem associations; access to study context at test was varied by inducing high and low degrees of contextual overlap between study and test. Results showed that the effects of part-list cuing depend critically on encoding and study context access. Depending on the combination of the two, part list cuing impaired, improved, or did not influence recall of the target items. A multimechanisms account of part-list cuing is provided to explain how part-list cuing affects target recall in the different experimental conditions. (PsycINFO Database Record PMID- 29578737 TI - Liking goes with liking: An intuitive congruence between preference and prominence. AB - In a series of 8 experiments, we demonstrate the existence of a "labeling effect" wherein people intuitively relate preferred choices to prominently labeled cues (such as heads as opposed to tails in a coin toss) and vice versa. Importantly, the observed congruence is asymmetric-it does not manifest for nonprominent cues and nonpreferred choices. This is because the congruence is driven by a process of evaluative matching: prominent cues are liked, but nonprominent cues are neutral or at most slightly negative in contrast. When we test prominent, yet truly negatively labeled cues, we indeed find a matching with less liked products. We discuss the theoretical contributions to the study of preferences and decision making, as well as demonstrate the practical implications to researchers and practitioners by using this process to assess intuitive preferences and reduce the compromise effect. (PsycINFO Database Record PMID- 29578738 TI - An exploration of the role of subordinate affect in leader evaluations. AB - Leadership research has been encumbered by a proliferation of constructs and measures, despite little evidence that each is sufficiently conceptually and operationally distinct from the others. We draw from research on subordinates' implicit theories of leader behavior, behaviorally anchored rating scales, and decision making to argue that leader affect (i.e., the degree to which subordinates have positive and negative feelings about their supervisors) underlies the common variance shared by many leadership measures. To explore this possibility, we developed and validated measures of positive and negative leader affect (i.e., the Leader Affect Questionnaires; LAQs). We conducted 10 studies to develop the five-item positive and negative LAQs and to examine their convergent, discriminant, predictive, and criterion-related validity. We conclude that a) the LAQs provide highly reliable and valid tools for assessing subordinates' evaluations of their leaders; b) there is significant overlap between existing leadership measures, and a large proportion of this overlap is a function of the affect captured by the LAQs; c) when the LAQs are used as control variables, in most cases, they reduce the strength of relationships between leadership measures and other variables; d) the LAQs account for significant variance in outcomes beyond that explained by other leadership measures; and e) there is a considerable amount of unexplained variance between leadership measures that the LAQs do not capture. Research suggestions are provided and the implications of our results are discussed. (PsycINFO Database Record PMID- 29578739 TI - Proactivity despite discouraging supervisors: The powerful role of prosocial motivation. AB - Although considerable research demonstrates that employees are unlikely to be proactive when they view their supervisors as discouraging this type of behavior, we challenge the assumption that this is true for all employees. Drawing on motivated information processing theory, we argue that prosocial motivation can spark employees to be proactive even when supervisors are perceived as discouraging. Specifically, prosocial motivation may weaken the negative relationship between perceived discouraging supervisor behaviors and proactivity by driving employees to bring about change to impact coworkers or the organization. Because they are less focused on self-interest and more focused on benefitting others, prosocially motivated employees are able to maintain their reason-to (felt responsibility for change) and can-do (efficacy to be proactive) motivation even when supervisors do not welcome proactivity. We test our hypotheses across three studies, using multisource data from employees and supervisors in two organizations (Studies 1a and 1b), and lagged data from employees working in a range of industries (Study 2). By identifying the mechanisms driving prosocially motivated employees to be proactive despite having supervisors who are perceived to be discouraging, we offer novel theoretical and practical insights regarding the effects of context on proactivity at work. (PsycINFO Database Record PMID- 29578740 TI - Confirmatory factor analysis of the Coping Strategies Questionnaire-Revised for veterans with pain. AB - As the need for appropriate assessment and treatment of veterans with chronic pain continues to grow, it is important to ensure that the instruments we use to complete these assessments, such as the Coping Strategies Questionnaire-Revised (CSQ-R), are validated on this population. The purpose of the present study was to confirm the factor structure of the CSQ-R in veterans. Secondary analyses examined associations between various pain coping strategies and measures of mood and health functioning. Participants consisted of 281 veterans who were referred to and evaluated by a Psychology Pain Management Program in a northeastern Department of Veterans Affairs health care facility. Participants completed self report questionnaires including the CSQ-R and measures of disability, mood, and health. Confirmatory factor analysis (CFA) compared the 6-factor solution to models identified in other studies. The CFA indicated that the 6-factor solution of the CSQ-R proposed by Riley and Robinson (1997) is valid and has the best fit of all models tested when used with veterans. The results of the secondary correlational analyses were consistent with previous research indicating that coping self-statements and ignoring pain are adaptive pain coping strategies. Our findings support the psychometric soundness of the 6-factor CSQ-R when used with veterans with chronic pain. (PsycINFO Database Record PMID- 29578742 TI - Experimental effects of mindfulness inductions on self-regulation: Systematic review and meta-analysis. AB - Self-regulation is the control of aspects of the self to allow pursuit of long term goals, and it is proposed as a central pathway through which mindfulness may exert benefits on well-being. However, the effects of a single mindfulness induction on self-regulation are not clear, as there has been no comprehensive review of this evidence. The current review synthesized existing findings relating to the effect of a mindfulness induction delivered in a laboratory setting on measures of self-regulation. Twenty-seven studies were included and grouped according to 3 outcomes: regulation of experimentally induced negative affect (k = 15; meta-analysis), emotion-regulation strategies (k = 7) and executive functions (k = 9; narrative synthesis). A mindfulness induction was superior to comparison groups in enhancing the regulation of negative affect (d = -.28). Executive-function performance was enhanced only when the experimental design included an affect induction or when the outcome was sustained attention. The effect on emotion-regulation strategies was inconclusive, but with emerging evidence for an effect on rumination. Overall, the findings indicate that, in the form of an induction, mindfulness may have the most immediate effect on attention mechanisms rather than exerting cognitive changes in other domains, as are often reported outcomes of longer mindfulness training. Through effecting change in attention, emotion regulation of negative affect can be enhanced, and subsequently, executive-function performance more quickly restored. The interpretations of the findings are caveated with consideration of the low quality of many of the included study designs determined by the quality appraisal tool. (PsycINFO Database Record PMID- 29578741 TI - Dysregulated behavioral responses to hedonic probes among youth with depression histories and their high-risk siblings. AB - Affect dysregulation in response to rewarding stimuli has been proposed as a vulnerability factor for major depressive disorder (MDD). However, it remains unclear how affective behavioral dynamics may be altered among individuals who are at high risk for depression but not currently depressed. We examined the dynamics of affective facial behavior during hedonic probes among 3 groups of adolescents: remitted probands who had histories of childhood-onset MDD (n = 187), never-depressed siblings of probands (high familial risk; n = 207), and healthy controls (n = 166). Participants' happy and sad facial expressions were coded during 3 hedonic laboratory tasks: receiving a preferred prize, describing a positive autobiographical memory, and watching a humorous film. Happy and sad behavioral dynamics were indexed by mean level- and time-dependent reactivity, variability (mean of the squared successive differences), and inertia (autocorrelation). Relative to controls, probands and siblings exhibited a more rapid decrease in happy behaviors, and probands exhibited higher inertia of sad behaviors during hedonic probes. Both probands and siblings exhibited lower inertia of sad behaviors while receiving a desired prize, which highlights the importance of context variation in testing hypotheses. Overall, our study provides new evidence that hedonic behavioral dysregulation, as reflected in dynamic facial behavior, may highlight depression vulnerability. (PsycINFO Database Record PMID- 29578743 TI - Stereotypes and prejudice affect the recognition of emotional body postures. AB - Most research on emotion recognition focuses on facial expressions. However, people communicate emotional information through bodily cues as well. Prior research on facial expressions has demonstrated that emotion recognition is modulated by top-down processes. Here, we tested whether this top-down modulation generalizes to the recognition of emotions from body postures. We report three studies demonstrating that stereotypes and prejudice about men and women may affect how fast people classify various emotional body postures. Our results suggest that gender cues activate gender associations, which affect the recognition of emotions from body postures in a top-down fashion. (PsycINFO Database Record PMID- 29578744 TI - The semantics of emotion in false memory. AB - The emotional valence of target information has been a centerpiece of recent false memory research, but in most experiments, it has been confounded with emotional arousal. We sought to clarify the results of such research by identifying a shared mathematical relation between valence and arousal ratings in commonly administered normed materials. That relation was then used to (a) decide whether arousal as well as valence influences false memory when they are confounded and to (b) determine whether semantic properties that are known to affect false memory covary with valence and arousal ratings. In Study 1, we identified a quadratic relation between valence and arousal ratings of words and pictures that has 2 key properties: Arousal increases more rapidly as function of negative valence than positive valence, and hence, a given level of negative valence is more arousing than the same level of positive valence. This quadratic function predicts that if arousal as well as valence affects false memory when they are confounded, false memory data must have certain fine-grained properties. In Study 2, those properties were absent from norming data for the Cornell Cortland Emotional Word Lists, indicating that valence but not arousal affects false memory in those norms. In Study 3, we tested fuzzy-trace theory's explanation of that pattern: that valence ratings are positively related to semantic properties that are known to increase false memory, but arousal ratings are not. (PsycINFO Database Record PMID- 29578745 TI - Boredom as a seeking state: Boredom prompts the pursuit of novel (even negative) experiences. AB - Building on functional models of emotion, we propose that boredom creates a seeking state that prompts people to explore new experiences, even if those experiences are hedonically negative. Specifically, as emotional responses fade, boredom motivates the pursuit of alternative experiences that differ from the experience that resulted in boredom. Participants who reported a higher degree of boredom after a neutral task were more likely to choose negative experiences (Study 1). Compared with a low-boredom condition, participants in a high-boredom condition desired novel experiences and, as a result of this desire, were more likely to choose novel negative experiences (Study 2). In Study 3, participants were made bored by positive or negative stimuli. Participants in the positive boredom conditions were more likely to choose a novel experience that was more negative; participants in the negative-boredom conditions were more likely to choose a novel experience that was more positive. These findings reveal that boredom motivates people to seek out novel experiences that elicit different (even more negative) feelings. (PsycINFO Database Record PMID- 29578746 TI - Visual features and perceptual context modulate attention towards evolutionarily relevant threatening stimuli: Electrophysiological evidence. AB - The snake detection hypothesis claims that predatory pressure from snakes has shaped the primate visual system, but we still know very little about how the brain processes evolutionarily important visual cues, and which factors are crucial for quick detection of snakes. We investigated how visual features modulate the electrophysiological markers of early attentional processes. In Experiment 1, we compared snake, rope, gun, and bird images to isolate the effects due to curvilinearity of the stimuli. The results showed that both snake and rope images elicited enhanced P1 and N1 event-related potential components as well as early posterior negativity (EPN). In Experiment 2, we studied whether nonthreatening curvilinear images (i.e., ropes) still elicit the enhanced electrophysiological responses when snake images are not presented as stimuli, and therefore the context does not provoke top-down attention to curvilinear shapes. Rope images still evoked an enhanced EPN, suggesting that curvilinear shapes are preferably captured by attentional processes. However, this effect was smaller than in Experiment 1, in which snake images were present. Thus, our results hint to the possibility that the perceptual context may interact with processing of shape information, drawing attention to curvilinear shapes when the presence of snakes is expectable. Furthermore, we observed that spatial frequency of the visual stimuli modulated especially the early electrophysiological responses, and decreased the differences between stimulus categories in EPN without completely eliminating them. The findings suggest that low-level and high level mechanisms interact to give an attentional priority to potentially threatening stimuli. (PsycINFO Database Record PMID- 29578747 TI - An experience sampling study examining the potential impact of a mindfulness based intervention on emotion differentiation. AB - Research has shown that how well people can differentiate between different emotional states is an essential requirement for adaptive emotion regulation. People with low levels of emotion differentiation tend to be more vulnerable to develop emotional disorders. Although we know quite a lot about the correlates of emotion differentiation, research on factors or interventions which could improve emotion differentiation skills is scarce. Here, we hypothesize, and study empirically, whether a mindfulness-based intervention (MBI) may impact the differentiation of negative and positive emotions. A within-subjects pre-, post-, and follow-up design involving experience sampling was used. At each phase participants reported their current emotions and mindfulness skills up to 40 times across 4 consecutive days using smartphones. Multilevel modeling showed a significant improvement in negative emotion differentiation postintervention and at 4 months of follow-up, and a significant improvement in positive emotion differentiation at 4 months follow-up. The improvement in negative emotion differentiation, however, was no longer significant when controlling for levels of negative affect. A time-lagged mediation model showed that posttreatment changes in mindfulness skills mediated subsequent changes in negative emotion differentiation, also when controlling for levels of negative affect. These results suggest that MBI is a promising approach to improve people's emotion differentiation skills. (PsycINFO Database Record PMID- 29578748 TI - Negative emotionality across diagnostic models: RDoC, DSM-5 Section III, and FFM. AB - The research domain criteria (RDoC) were established in an effort to explore underlying dimensions that cut across many existing disorders and to provide an alternative to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). One purpose of the present study was to suggest a potential alignment of RDoC negative valence with 2 other dimensional models of negative emotionality: five-factor model (FFM) neuroticism and the DSM-5 Section III negative affectivity. A second purpose of the study, though, was to compare their coverage of negative emotionality, more specifically with respect to affective instability. Participants were adult community residents (N = 90) currently in mental health treatment. Participants received self-report measures of RDoC negative valence, FFM neuroticism, and DSM-5 Section III negative affectivity, along with measures of affective instability, borderline personality disorder, and impairment. Findings suggested that RDoC negative valence is commensurate with FFM neuroticism and DSM-5 Section III negative affectivity, and it would be beneficial if it was expanded to include affective instability. (PsycINFO Database Record PMID- 29578750 TI - Operative Management of Acute Triceps Tendon Ruptures: Review of 184 Cases. AB - BACKGROUND: Distal triceps tendon ruptures are rare. The authors present a series of 184 surgically treated, acute, traumatic triceps tendon avulsions and compare the complications between those treated with anchors (A) versus transosseous (TO) suture repair. HYPOTHESIS: No difference exists in the retear rate between TO and A repairs. Study Designed: Cohort study; Level of evidence, 3. METHODS: All patients who underwent an open primary repair of a traumatic triceps tendon avulsion within 90 days of injury, between 2007 and 2015, were retrospectively reviewed. Surgeries were performed within a multisurgeon (75 surgeons), multicenter (14 centers), community-based integrated health care system. Patient demographic information, type of repair, complications, and time from surgery to release from medical care were recorded. RESULTS: 184 triceps tears in 181 patients met the inclusion criteria. The mean age was 49 years (range, 15-83 years). There were 169 males. The most common mechanisms of injury were fall (56.5%) and weight lifting (19%). Mean time from injury to surgery was 19 days (range, 1-90 days); in 74.5% of cases, surgery was performed in 3 weeks or less. There were 105 TO and 73 A repairs. No significant difference was found between the two groups in the mean age ( P = .18), sex ( P = .51), completeness of tears ( P = .74), tourniquet time ( P = .455), and prevalence of smokers ( P = .64). Significant differences were noted between TO and A repairs in terms of reruptures (6.7% vs 0%, respectively; P = .0244), overall reoperation rate (9.5% vs 1.4%; P = .026), and release from medical care (4.3 vs 3.4 months; P = .0014), but no difference was seen in infection rate (3.8% vs 0%; P = .092). No difference was noted in release from medical care in patients who underwent surgery 3 weeks or less after injury compared with those undergoing surgery more than 3 weeks after injury (3.90 vs 4.09 months, respectively; P = .911). CONCLUSION: Primary repair of triceps ruptures with TO fixation has a significantly higher rerupture rate, higher reoperation rate, and longer release from medical care than does repair with A fixation. Implementation of suture anchors in triceps repairs offers a lower complication rate and earlier release from medical care. PMID- 29578749 TI - Positive End-Expiratory Pressure Ventilation Induces Longitudinal Atrophy in Diaphragm Fibers. AB - RATIONALE: Diaphragm weakness in critically ill patients prolongs ventilator dependency and duration of hospital stay and increases mortality and healthcare costs. The mechanisms underlying diaphragm weakness include cross-sectional fiber atrophy and contractile protein dysfunction, but whether additional mechanisms are at play is unknown. OBJECTIVES: To test the hypothesis that mechanical ventilation with positive end-expiratory pressure (PEEP) induces longitudinal atrophy by displacing the diaphragm in the caudal direction and reducing the length of fibers. METHODS: We studied structure and function of diaphragm fibers of mechanically ventilated critically ill patients and mechanically ventilated rats with normal and increased titin compliance. MEASUREMENTS AND MAIN RESULTS: PEEP causes a caudal movement of the diaphragm, both in critically ill patients and in rats, and this caudal movement reduces fiber length. Diaphragm fibers of 18-hour mechanically ventilated rats (PEEP of 2.5 cm H2O) adapt to the reduced length by absorbing serially linked sarcomeres, the smallest contractile units in muscle (i.e., longitudinal atrophy). Increasing the compliance of titin molecules reduces longitudinal atrophy. CONCLUSIONS: Mechanical ventilation with PEEP results in longitudinal atrophy of diaphragm fibers, a response that is modulated by the elasticity of the giant sarcomeric protein titin. We postulate that longitudinal atrophy, in concert with the aforementioned cross-sectional atrophy, hampers spontaneous breathing trials in critically ill patients: during these efforts, end-expiratory lung volume is reduced, and the shortened diaphragm fibers are stretched to excessive sarcomere lengths. At these lengths, muscle fibers generate less force, and diaphragm weakness ensues. PMID- 29578751 TI - In Vitro and In Vivo Performance of Tissue-Engineered Tendons for Anterior Cruciate Ligament Reconstruction. AB - BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is the current standard of care for ACL tears. However, the results are not consistently successful; autografts or allografts have certain disadvantages; and synthetic grafts have had poor clinical results. PURPOSE: To determine if recellularization of decellularized tendons combined with mechanical stimulation in a bioreactor could replicate the mechanical properties of the native ACL and be successfully used for ACL reconstruction in vivo. STUDY DESIGN: Controlled laboratory study. METHODS: Porcine tibialis tendons were decellularized and then recellularized with human adult bone marrow-derived stem cells. Tendons were cultured in a tissue bioreactor that provided biaxial cyclic loading for up to 7 days. To reproduce mechanical stresses similar to those experienced by the ACL within the knee joint, the tendons were subjected to simultaneous tension and torsion in the bioreactor. Expression of tendon-specific genes and newly synthesized collagen and glycosaminoglycan were used to quantify the efficacy of recellularization and dynamic bioreactor culture. The ultimate tensile load to failure and stiffness of recellularized constructs were measured after dynamic stimulation. Finally, the tissue-engineered tendons were used to reconstruct the ACL in 24 pigs, and ultimate tensile load to failure and stiffness were assessed after 3 months. RESULTS: Dynamic bioreactor culture significantly increased the expression of tendon-specific genes, the quantity of newly synthesized collagen and glycosaminoglycan, and the ultimate tensile load and stiffness of recellularized tendons. After in vivo reconstruction, the ultimate tensile load and stiffness of the tissue-engineered tendons increased significantly up to 3 months after surgery and were within 80% of the ultimate tensile load of the natural ACL. CONCLUSION: This translational study indicates that recellularization and dynamic mechanical stimuli can significantly enhance matrix synthesis and ultimate tensile load of decellularized porcine tibialis tendons. This approach to tissue engineering can be very useful for ACL reconstruction and may overcome some of the disadvantages of autografts and allografts. CLINICAL RELEVANCE: Dynamic bioreactor cultivation of tissue-engineered tendons may overcome the limitations of autografts and allografts.

PMID- 29578753 TI - Can Mother-Daughter Communication Buffer Adolescent Risk for Mental Health Problems Associated With Maternal Depressive Symptoms? AB - The current study sought to test whether higher quality mother-daughter communication would buffer associations between maternal depressive symptoms and girls' internalizing and externalizing psychopathology symptoms among urban African American girls across a 12-month period. One hundred ninety-four treatment-seeking urban African American adolescent girls, ages 12-16, and their mothers participated in the study. Every 6 months (for up to 3 assessments), daughters reported on their internalizing and externalizing symptoms, mothers reported on their depressive symptoms, and both mothers and daughters reported on the quality of their dyadic communication. Daughters additionally reported on the extent to which they felt accepted by their mothers at each assessment. Results of multilevel modeling revealed that quality of communication significantly interacted with maternal depressive symptoms to predict externalizing and internalizing symptoms in daughters, such that the risk associated with maternal depressive symptoms was fully buffered for daughters in high-quality communication dyads. Secondary analyses demonstrated that these patterns of results were not accounted for by higher levels of social status or maternal acceptance. Drawing on a vulnerable and understudied population of urban African American adolescent girls, this work suggests that family communication may contribute to important intergenerational psychopathology transmission processes, above and beyond more general features of the family environment.

AB - Objective This study investigates the neural basis of inattentional deafness, which could result from task irrelevance in the auditory modality. Background Humans can fail to respond to auditory alarms under high workload situations. This failure, termed inattentional deafness, is often attributed to high workload in the visual modality, which reduces one's capacity for information processing. Besides this, our capacity for processing auditory information could also be selectively diminished if there is no obvious task relevance in the auditory channel. This could be another contributing factor given the rarity of auditory warnings. Method Forty-eight participants performed a visuomotor tracking task while auditory stimuli were presented: a frequent pure tone, an infrequent pure tone, and infrequent environmental sounds. Participants were required either to respond to the presentation of the infrequent pure tone (auditory task-relevant) or not (auditory task-irrelevant). We recorded and compared the event-related potentials (ERPs) that were generated by environmental sounds, which were always task-irrelevant for both groups. These ERPs served as an index for our participants' awareness of the task-irrelevant auditory scene. Results Manipulation of auditory task relevance influenced the brain's response to task irrelevant environmental sounds. Specifically, the late novelty-P3 to irrelevant environmental sounds, which underlies working memory updating, was found to be selectively enhanced by auditory task relevance independent of visuomotor workload. Conclusion Task irrelevance in the auditory modality selectively reduces our brain's responses to unexpected and irrelevant sounds regardless of visuomotor workload. Application Presenting relevant auditory information more often could mitigate the risk of inattentional deafness. PMID- 29578756 TI - Quantitative Trait Loci for Early- and Late-Developing Skull Characters in Mice: A Test of the Genetic Independence Model of Morphological Integration. AB - Quantitative genetical theory suggests that characters existing in developmentally or functionally integrated groups are expected to be genetically correlated because they share a common inheritance. The genetic independence model for the cause of this genetic integration predicts that pleiotropic effects of single genes are mostly restricted to the characters in these integrated groups. We tested this model by estimating the additive and dominance effects of quantitative trait loci (QTLs) affecting early- (cranial vault) and late developing (face) skeletal characters in F2 house mice originally derived from a cross of the Large and Small inbred strains. Interval mapping procedures were used that resulted in the identification of 26 QTLs on 17 of the 19 autosomes that significantly affected these characters. Additive, but not dominance, genotypic effects of many of these QTLs predominantly affected either the cranial vault or face characters, which supports the genetic independence model. Only two QTLs had positive pleiotropic effects on one group of characters but negative pleiotropic effects on the other (antagonistic pleiotropy). PMID- 29578757 TI - The Evolution of Mating Preferences and Major Histocompatibility Complex Genes. AB - House mice prefer mates genetically dissimilar at the major histocompatibility complex (MHC). The highly polymorphic MHC genes control immunological self/nonself recognition; therefore, this mating preference may function to provide "good genes" for an individual's offspring. However, the evidence for MHC dependent mating preferences is controversial, and its function remains unclear. Here we provide a critical review of the studies on MHC-dependent mating preferences in mice, sheep, and humans and the possible functions of this behavior. There are three adaptive hypotheses for MHC-dependent mating preferences. First, MHC-disassortative mating preferences produce MHC heterozygous offspring that may have enhanced immunocompetence. Although this hypothesis is not supported by tests of single parasites, MHC heterozygotes may be resistant to multiple parasites. Second, we propose that MHC-dependent mating preferences enable hosts to provide a "moving target" against rapidly evolving parasites that escape immune recognition (the Red Queen hypothesis). Such parasites are suspected to drive MHC diversity through rare-allele advantage. Thus, the two forms of parasite-mediated selection thought to drive MHC diversity, heterozygote and rare-allele advantage, will also favor MHC-dependent mating preferences. Finally, MHC-dependent mating preferences may also function to avoid inbreeding; a hypothesis consistent with other evidence that MHC genes play a role in kin recognition. PMID- 29578758 TI - Plumage Reflectance and the Objective Assessment of Avian Sexual Dichromatism. AB - Assessment of color using human vision (or standards based thereon) is central to tests of many evolutionary hypotheses. Yet fundamental differences in color vision between humans and other animals call this approach into question. Here we use techniques for objectively assessing color patterns that avoid reliance on species-specific (e.g., human) perception. Reflectance spectra are the invariant features that we expect the animal's color cognition to have evolved to extract. We performed multivariate analyses on principal components derived from >2,600 reflectance spectra (300-720 nm) sampled in a stratified random design from different body regions of male and female starlings in breeding plumage. Starlings possess spatially complex plumage patterns and extensive areas of iridescence. Our study revealed previously unnoticed sex differences in plumage coloration and the nature of iridescent and noniridescent sex differences. Sex differences occurred in some body regions but not others, were more pronounced at some wavelengths (both ultraviolet and human visible), and involved differences in mean reflectance and spectral shape. Discriminant analysis based on principal components were sufficient to sex correctly 100% of our sample. If hidden sexual dichromatism is widespread, then it has important implications for classifications of animals as mono- or dimorphic and for taxonomic and conservation purposes. PMID- 29578759 TI - Does Host Self-Regulation Increase the Likelihood of Insect-Pathogen Population Cycles? PMID- 29578760 TI - How Habitat Edges Change Species Interactions. AB - Traditionally, ecologists interested in habitat edges have focused on edge related gradients in patterns of species richness or abiotic variables. Here, however, we take a different perspective, attempting to synthesize recent empirical results concerning the effects of habitat edges on population dynamics with contemporary theoretical developments to outline the ways in which species interactions, and the dynamics of the communities in which they are embedded, can be changed by habitat edges. We find a striking convergence between empirical notions of a patch's core area and analytical results from partial differential equation models. A review of both empirical and theoretical studies suggests four general classes of mechanisms through which habitat edges can have similar impacts on dissimilar types of species interactions. Specifically, we focus on edges' roles as dispersal barriers or filters, edges' influences on mortality, edges' involvement in spatial subsidies (in which dispersers' intrapatch impacts are maintained by their activities in other habitats), and edges' roles as generators of novel interactions. For each class of edge-mediated effects, we provide examples of how one can use spatial modeling to address the relevant questions on these topics, which together form a key link between community dynamics and landscape structure. PMID- 29578761 TI - Corridor Use Predicted from Behaviors at Habitat Boundaries. AB - Through empirical studies and simulation, I demonstrate how simple behaviors can be used in lieu of detailed dispersal studies to predict the effects of corridors on interpatch movements. Movement paths of three butterfly species were measured in large (1.64 ha) experimental patches of open habitat, some of which were connected by corridors. Butterflies that "reflected" off boundaries between open patches and the surrounding forest also emigrated from patches through corridors at rates higher than expected from random movement. This was observed for two open-habitat species, Eurema nicippe and Phoebis sennae; however, edges and corridors had no effect on a habitat generalist, Papilio troilus. Behaviorally based simulation models, which departed from correlated random walks only at habitat boundaries, predicted that corridors increase interpatch movement rates of both open-habitat species. Models also predicted that corridors have proportionately greater effects as corridor width increases, that movement rates increase before leveling off as corridor width increases, and that corridor effects decrease as patch size increases. This study suggests that corridors direct movements of habitat-restricted species and that local behaviors may be used to predict the conservation potential of corridors in fragmented landscapes. PMID- 29578762 TI - Males Feeding Females during Incubation. I. Required by Microclimate or Constrained by Nest Predation? AB - Nest attentiveness (percentage of time spent on the nest) during incubation represents a parent-offspring conflict; incubating birds must balance a trade-off between caring for embryos by staying on the nest versus caring for themselves by getting off the nest to forage. For species in which females are the sole incubator, males can potentially affect this trade-off and increase nest attentiveness by feeding incubating females on the nest (incubation feeding). Increased nest attentiveness may be required when local microclimate conditions are harsh and thereby require greater incubation feeding (microclimate hypothesis). Alternatively, incubation feeding may be constrained by risk of attracting nest predators (nest predation hypothesis), which in turn may constrain female nest attentiveness because of energy limitation. We show that incubation feeding rates are much greater among cavity-nesting than among coexisting open-nesting birds. Under the microclimate hypothesis, the greater incubation feeding rates of cavity-nesting birds generate the prediction that microclimate should be harsher than for open-nesting birds. Our results reject this hypothesis because we found the opposite pattern; cavity-nesting birds experienced more moderate (less variable) microclimates that were less often below temperatures (i.e., 16 degrees C) that can negatively impact eggs compared with open-nesting species. In contrast, incubation feeding rates were highly negatively correlated with nest predation both within and between the two nest types, supporting the nest predation hypothesis. Incubation feeding in turn was positively correlated with nest attentiveness. Thus, nest predation may indirectly affect female incubation behavior by directly affecting incubation feeding by the male. PMID- 29578763 TI - The Adaptive Dynamics of Consumer Choice. AB - This article uses mathematical models to investigate the consequences of noninstantaneous choice between two prey types by a predator. The models are characterized by three features: sustained cycles in predator and prey population sizes, a trade-off between the predator's consumption rates of the two prey and adaptive adjustment of the consumption rates at a rate proportional to the change in predator fitness per unit change in consumption rates. Adaptive adjustment of consumption rates frequently prevents the system from achieving an ideal free distribution of predator foraging effort and frequently results in chaotic dynamics or alternative attractors. The process of switching to consume the more common prey can reduce the minimum density of one or both prey. These phenomena occur for a variety of different models, including models in which both prey are in the same or in distinct habitats. An ideal free distribution can often be attained by adding prey refuges or immigration, provided these have a large enough effect on the dynamics of the system. The dynamics of switching can be important in determining indirect interactions between prey species and other aspects of food web dynamics. PMID- 29578764 TI - The Implications of Experimental Design for Biodiversity Manipulations. AB - I report a simulation study that tested the ability of a variety of experimental designs to achieve two fundamental goals: (1) to determine the association between loss of biological diversity and responses such as ecosystem functioning and (2) to determine which components of biodiversity, such as number of species, functional diversity, or a keystone species, were most responsible for that association. For the goal of reliably detecting an overall association, all designs I tested performed well and were unlikely to misidentify predominant patterns. Thus, this study affirms the common conclusion of many published biodiversity experiments that loss of biological diversity is often associated with a reduction in ecosystem functioning. However, for the goal of identifying the components of biodiversity that are most responsible for the effects, designs differed markedly. Some designs performed well in detecting number-of-species effects but poorly in detecting effects of unique species or functional groups. No design tested was able to discriminate both numeric effects and compositional effects in all situations. Thus, this study demonstrates that interpreting results about mechanisms from biodiversity experiments will be critically dependent on an experiment's design. PMID- 29578765 TI - The Evolution of Search Modes: Ecological versus Phylogenetic Perspectives. AB - Both theoretical and empirical studies, many of them on lizards, suggest that foraging behaviors often take one of two forms, sometimes called "modes": active search or sedentary ambush. I tested this by expanding the database on lizard foraging behaviors and testing for the existence of modality in this much larger database. My findings did not support the validity of some previous analyses. Greatly expanded lizard data did not show a bimodal distribution of foraging behaviors. Phylogeny, however, was a strong predictor of behavior. One clade, Autarchoglossa, was characterized by a wide range of foraging behaviors, but closely related species tended to exhibit similar behaviors. Two other clades, Iguania and Gekkota, retain the ancestral sedentary behavior. This phylogenetic trend, combined with phylogenetically biased sampling, may have been responsible for the appearance of bimodality in previous studies. Thus, bimodality of search modes is rejected. Some previous generalizations regarding correlates of foraging "mode" need to be reevaluated in this light. PMID- 29578766 TI - Diversity in Relation to Body Size in Mammals: A Comparative Study. AB - A wide variety of higher taxa show right-skewed frequency distributions of species' body sizes, and a negative relationship is often found between the number of species within a taxonomic group and its mean size. These patterns may arise from essentially random cladogenesis and extinction, from the tendency of organisms to anagenetically track a relatively small optimal size, or from high rates of cladogenesis at relatively small sizes. We used body mass data for about 65% of the world's mammal species to test the predictions of these alternative mechanisms. Using phylogenetically independent contrasts to control for phylogeny and clade age, we found that although size does not appear to be a general correlate of diversity, large radiations of species do tend to be small bodied. This pattern seems most consistent with the hypothesis that the number of niches is potentially greatest for small-bodied taxa.

AB - We demonstrated that the presence of invulnerable prey can result in a shift in the balance between top-down and bottom-up control of a model food chain. Our model food chain consisted of the bacterium Escherichia coli and the bacteriophage T4 (a virus that feeds on E. coli) in chemostats supplied with different concentrations of glucose. The E. coli population consisted of individuals that were susceptible to predation by T4 ("edible" E. coli) and individuals that were resistant to predation by T4 ("inedible" E. coli). The equilibrium density of a heterogeneous prey population (consisting of edible and inedible E. coli) increased strongly in response to an enrichment of its resources. This response consisted of an increase in the inedible fraction of the prey population but no change in the edible fraction. In contrast, a homogeneous prey population (edible E. coli only) increased only marginally. The equilibrium density of the predator population (bacteriophage T4) did not significantly increase in response to enrichment when its prey were heterogeneous, but it increased strongly when its prey were homogeneous. PMID- 29578769 TI - Top-Down Control of Cyanobacteria: A Theoretical Analysis. AB - Field patterns and experimental results suggest that the effect of zooplankton grazing on the abundance of large colonial cyanobacteria may differ strongly from case to case. In this article we present an extensive analysis of a model that describes the competition between cyanobacteria of the Oscillatoria group and green algae exploited by Daphnia. In particular, we study the response of the model to changes in the nutrient concentration and predation by zooplanktivorous fish. The analysis is repeated for an array of different assumptions on the nutritional value of cyanobacteria and selectivity of zooplankton grazing. When fish predation pressure is so high that Daphnia density is negligible, there is competitive exclusion between the two primary producers, and over a range of nutrient levels, there are two alternative attractors: one with only cyanobacteria and one with only green algae. When fish predation pressure is lower, zooplankton becomes important, and if grazing by these animals is sufficiently selective, this may cause a third attractor on which Daphnia, cyanobacteria, and algae coexist. This "mixed" attractor may be stationary, oscillatory, or chaotic. Depending on the nutrient level, the nutritional value of cyanobacteria, and the selectivity of zooplankton, cyanobacterial dominance may be either induced or eliminated in response to reduced fish predation. This is well in line with the confusing array of field studies and experimental results. PMID- 29578770 TI - Erratum. PMID- 29578771 TI - The Temporal Coherence of Zooplankton Population Abundances in Neighboring North Temperate Lakes. AB - We investigated the temporal coherence (i.e., the correlation or synchrony between time series) of annual abundances among populations of freshwater zooplankton in eight lakes in Ontario, Canada, from 1980 to 1992. We estimated temporal coherence using the intraclass correlation coefficient (ri). While values of ri were relatively low among comparisons of all eight lakes, they were statistically significant for three of the seven common cladoceran and copepod taxa (Bosmina longirostris, Leptodiaptomus minutus, and Mesocyclops edax). These significant positive correlations imply that a portion of the interannual variation in abundance was produced by factors operating on a scale larger than the individual lake catchments. Because the eight-lake analysis might obscure strong, but conflicting, patterns among lakes in the region, we identified homogeneous and temporally coherent subsets of lakes for each species using an exploratory stepwise deletion procedure. The resultant homogeneous subsets exhibited much greater temporal coherence, accounting for 47% (Eubosmina) to 84% (Leptodiaptomus) of the interannual variation in abundance. Our results suggest that the factors affecting annual variation in zooplankton abundance must be sought both within lakes and beyond their watersheds. PMID- 29578772 TI - Sex-Ratio Selection in Species with Helpers at the Nest: The Repayment Model Revisited. AB - We reexamine the theoretical and empirical basis for the "repayment model" of Emlen, Emlen, and Levin, which predicts that the overall sex ratio of offspring in cooperative-breeding species with helpers at the nest should be biased toward the more helpful sex. We conclude that in theory the model may yield a biased sex ratio but only under restricted conditions that are unlikely to be met in most populations. In those cases where the model is potentially applicable, estimates of both direct and indirect fitness of sons and daughters are necessary in order to avoid double accounting. As a result, extensive demographic data are required to determine the expected sex-ratio bias. Empirically, none of the three examples originally suggested as supporting the repayment model withstand critical scrutiny. Using long-term demographic data from two populations of one of these species, the red-cockaded woodpecker (Picoides borealis), we determine that the model predicts a biased sex ratio not observed in the data. This suggests that confounding factors may counter the sex-ratio bias predicted by the model, that the extensive empirical data available for this species may be insufficient to test the model, or that there are as yet unknown theoretical difficulties with the model. Finally, we discuss the recently reported case of the Seychelles warbler (Acrocephalus sechellensis). The extraordinarily biased sex ratios reported in this species are in accord with those predicted by the model when applied at the scale of individual groups but not at the population level. Additional empirical work is necessary to determine what, if any, the generality and usefulness of the repayment model may be. PMID- 29578773 TI - Reptile Extinctions on Land-Bridge Islands: Life-History Attributes and Vulnerability to Extinction. AB - One of the central questions of conservation biology is what life-history traits render a species prone to extinction. We addressed this problem by calculating extinction rates for 35 species of turtles and squamates (lizards and snakes) occurring on 87 land-bridge islands in the Mediterranean Sea. We calculated extinction rates in two ways: first, by incorporating the known sequence of historical island separations and second by ignoring history and assuming that the islands became isolated simultaneously. The second procedure is simpler and more frequently used in the literature and produces estimates of extinction rates that are similar to the first, more complex procedure. We then determined the relationship between extinction rates (calculated using both methods) and body mass, longevity, habitat specialization, and population abundance using two methods: first, by accounting for the phylogenetic relationships among species and, second, by ignoring them. Only population abundance and habitat specialization explained a significant amount of the observed variation in species extinction rates. Body mass itself did not explain variation in extinction rates, although it was strongly correlated with abundance. These conclusions were obtained using both procedures for calculating extinction rates and both procedures for correlating extinction rates with life-history traits. PMID- 29578774 TI - Greater Static Anterior Tibial Subluxation of the Lateral Compartment After an Acute Anterior Cruciate Ligament Injury Is Associated With an Increased Posterior Tibial Slope. AB - BACKGROUND: Static anterior tibial subluxation of the lateral compartment after an anterior cruciate ligament (ACL) injury highlights an increased anterior position of the tibia relative to the femur. However, the precise cause of this phenomenon is not entirely clear. Recently, an increased posterior tibial slope (PTS) has been identified as an independent risk factor for noncontact ACL injuries. HYPOTHESIS: An increased PTS is associated with an increased anterior position of the lateral compartment of the tibia relative to the femur after acute ACL injuries. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: From March 2016 to March 2017, a total of 154 patients with clinically diagnosed noncontact ACL injuries who underwent primary ACL reconstruction were retrospectively analyzed. Static anterior subluxation of the lateral compartment relative to the lateral femoral condyle was measured on preoperative magnetic resonance imaging. Among them, 23 patients (study group) who demonstrated >=6-mm anterior subluxation of the lateral compartment were matched in a 1:1 fashion to 23 control participants (control group), who showed <6-mm anterior subluxation of the lateral compartment. The PTS was measured on routinely available preoperative weightbearing lateral knee radiographs. Predictors of increased (>=6 mm) static anterior subluxation of the lateral compartment, including body mass index (BMI), PTS, injuries to the anterolateral ligament (ALL), and concomitant lateral meniscal lesions, were assessed by multivariable conditional logistic regression analysis. RESULTS: The mean PTS in the study group was 15.4 degrees , which was significantly larger than that in the control group (8.8 degrees ) ( P < .001). In addition, an abnormal degree of PTS (>=10.0 degrees ) was determined to be an independent risk factor (odds ratio, 8.0 [95% CI, 2.7-29.2]; P < .001) associated with >=6-mm anterior subluxation of the lateral compartment after acute ACL injuries. However, BMI, presence of concomitant lateral meniscal lesions, and presence of ALL ruptures were not. CONCLUSION: An increased PTS was identified to be an independent anatomic risk factor of increased (>=6 mm) anterior subluxation of the lateral compartment in acute noncontact ACL injuries. For patients with obviously increased anterior tibial subluxation of the lateral compartment after ACL injuries, the PTS should be measured. PMID- 29578775 TI - Migration, Virulence, and the Geographic Mosaic of Adaptation by Parasites. AB - The geographic mosaic theory of coevolution is predicated on structured populations of interacting species where gene flow and the force of selection can vary among populations, leading to a mosaic of traits in space. Here, I briefly review some recent studies of adaptation by a sterilizing parasite to structured populations of a freshwater snail. The results show geographic structure as expected under the geographic mosaic model. I then consider the effects of virulence and migration on local adaptation by parasites using a computer simulation. The results suggest that high virulence and low migration contribute to the strength of local adaptation by parasites. Highly virulent parasites showed adaptation to local hosts for migration rates of up to 10% of the population per generation. In addition, because of the dynamic nature of host parasite coevolution, the magnitude of local adaptation fluctuates over time. During some points in the cycle, parasites may be no more effective at infecting individuals from local host populations, even though they would be shown to be locally adapted if examined over enough generations. Contrary to expectation, parasite local adaptation was not affected by giving the parasite a longer generation time than the host, but differences in local selection intensities had a dramatic effect. PMID- 29578776 TI - Mutualism in Metapopulations of Legumes and Rhizobia. AB - Coevolution in mutualisms may result in a stable mosaic pattern of spatial differentiation, with regions occupied by different coadapted pairs of mutualists each being resistant to invasion by organisms with alternative phenotypes. The evolution of geographic mosaic patterns was analyzed for symbioses of legume plants and root-nodule bacteria (rhizobia), where plants are commonly polymorphic for genes affecting mutualism specificity. Typically, some alleles confer broad compatibility, and others restrict the set of bacterial genotypes accepted by plants as mutualist partners. Metapopulation simulation models with genetic assumptions matching the observed form of symbiotic specificity show that selection can generate a stable geographic mosaic if certain conditions are satisfied regarding competitive abilities, fitness benefits from mutualism, and migration rates. The structure of geographic variation in natural populations of the annual legume Amphicarpaea bracteata, together with patterns of variation in symbiotic fitness, is consistent with the interpretation that a mosaic pattern of differentiation may exist. Experimental and observational studies necessary to test more rigorously for mosaic distributions are outlined. PMID- 29578777 TI - Spatial and Temporal Patterns in Coevolving Plant and Pathogen Associations. AB - Spatial structuring is important in understanding the ecological and evolutionary dynamics of natural populations since local demes are rarely, if ever, completely isolated from neighboring demes. Plant host-pathogen interactions provide good examples of coevolutionary systems where both numerical and genetic dynamics have been explicitly investigated in a spatial context and where genes under selection can be unambiguously identified. In this article, we focus on long-term studies of several natural host-pathogen interactions that span a range of life histories and taxa. We use these studies to evaluate some predictions for numerical and genetic patterns at local and regional scales. Specifically, we examine the degree of among-population asynchrony in disease presence/absence and abundance, and the extent to which this is a function of isolation. For one host-pathogen interaction (Linum-Melampsora), we focus on whether there is local correspondence between resistance and virulence genes (as would be predicted by single population coevolutionary models) or whether such correspondence occurs at larger spatial scales. Finally, we discuss the implications of these studies with respect to the impact of host and pathogen life-history variation on the spatial scale of coevolutionary interactions. Understanding coevolutionary interactions in nature requires a multidisciplinary approach, including long-term empirical studies of multiple populations and computer modeling. PMID- 29578778 TI - Geographic Patterns in the Evolution of Resistance and Virulence in Drosophila and Its Parasitoids. AB - Many insects are attacked by internal parasitoids against which they mount a largely cellular immunological defense. The resistance of a host and the virulence of a parasitoid determine which species survives after parasitism. Drosophila is parasitized by several hymenopterous parasitoids, especially those in the genera Asobara and Leptopilina. Geographic patterns have been found in parasitoid virulence and host resistance, the clearest of which is a cline in Asobara tabida virulence from the north (low) to the south (high) of Europe. Drosophila melanogaster resistance is highest in central-southern Europe and lower elsewhere. We review and interpret these patterns in the light of recent experimental and theoretical studies of the evolution and coevolution of these traits. We find no evidence for genotype-specific virulence and defense, which makes "Red Queen"-type coevolution unlikely. The most important explanation for the patterns is geographic differences in host-parasitoid community structure. Asobara tabida virulence is positively correlated with the resistance of its main hosts, and there is more limited evidence that D. melanogaster resistance is influenced by the virulence of its parasitoids. We critically appraise whether the evidence available so far supports a coevolutionary explanation for the levels of these traits. PMID- 29578779 TI - The Selection Mosaic and Diversifying Coevolution between Crossbills and Lodgepole Pine. AB - Asymmetrical competition determines which of two seed predators drives the evolution of lodgepole pine (Pinus contorta ssp. latifolia) cones. Red squirrels (Tamiasciurus hudsonicus) are effective preemptive competitors in lodgepole pine forests so that red crossbills (Loxia curvirostra) are uncommon and selection from Tamiasciurus drives cone evolution. When Tamiasciurus are absent, crossbills increase in abundance and coevolve in an evolutionary arms race with pine. Similarly, Tamiasciurus alters the evolutionary trajectories of large-seeded pines, many of which rely on birds (Corvidae) for their seed dispersal. Populations therefore exhibit a selection mosaic with coevolutionary hot spots. In the coevolutionary hot spots, divergent selection on crossbills potentially leads to reproductive isolation and speciation. This results in a subsequent reduction in the geographic mosaic but diversifies the adaptive landscape on which crossbills have radiated. Thus, divergent selection is a double-edged sword. Divergent selection is critical in creating a selection mosaic but erodes the selection mosaic when it promotes reproductive isolation and speciation. PMID- 29578780 TI - A Comparison of the Taxonomic Richness of Vascular Plants in China and the United States. AB - Numbers of taxa at the level of order, family, genus, and species were tabulated for 12 subclass-level taxonomic groups of vascular plants in the floras of China and the United States. Analysis of these data showed that the flora of China is significantly more diverse than that of the United States. Furthermore, the difference in diversity arises at and below the level of genera. Finally, the euasterids II and Caryophyllidae are exceptions to the general trend in being more diverse in the United States. As a result, the floras of China and the United States are different nonrandom samples of the floras of the North Temperate Zone and the world. Phylogenetically older groups have a larger proportion of genera shared between China and the United States and also tend to have larger proportions of taxa belonging to genera with tropical affinities. The two subclass-level groups that are more diverse in the United States have primarily temperate affinities and are relatively young phylogenetically. We conclude that the patterns of diversity of Chinese and U.S. vascular plants have been influenced by the longer and more open access of temperate eastern Asia to tropical regions, the presence in southern China of a larger area of subtropical climate with complex topography, and the reduced impact of late Tertiary climate cooling in eastern Asia compared to North America. The greatest differences in diversity occur among older groups having stronger tropical affinities and, perhaps, originating in eastern Asia. In the North American flora, these groups appear to be disproportionately small relicts of a formerly widespread "boreotropical flora" that was relatively homogeneous at the genus level across the Bering Land Bridge between eastern Asia and North America. Groups that arose and diversified later, and that have fewer genera in common between Asian and North American floras, particularly the euasterids II, were better adapted to the cooler and drier climates of the Neogene temperate latitudes and evidently were relatively unaffected by late Neogene glaciations. These groups are thus as diverse, or more diverse, in North America as in eastern Asia. Understanding the relative diversity of two regions requires an appreciation of the historical development of the floras in the context of large-scale processes and events. PMID- 29578781 TI - Increasing Genomic Complexity by Gene Duplication and the Origin of Vertebrates. AB - Prevailing hypotheses concerning the origin of the vertebrate genome postulate successive genome duplications before the origin of fishes or tetrapods. These hypotheses predict episodic expansion of gene families early in vertebrate evolution (mostly before the origin of fishes), tetralogous relationships between gene copies samples from invertebrates and vertebrates, and gene family trees with symmetrical shapes. None of these predictions were evident from a phylogenetic analysis of 35 gene families. Overall, the results do not refute the hypothesis that gene family evolution is governed by independent gene duplications occurring with identical probability across gene lineages. These results suggest that the genome complexity of contemporary vertebrates mostly reflect small-scale (regional) DNA duplications instead of large-scale (genomic) duplications. PMID- 29578782 TI - The Evolutionary Advantages of Dying Young: Epidemiological Implications of Longevity in Metapopulations. AB - Here we show that pathogen-mediated selection can influence the evolution of host longevity. Greater longevity can impair the fitness of host organisms subject to pathogen attack, by reducing the mortality rate of infected hosts and thus creating a larger and more persistent reservoir of disease, from which infection can spread to the healthy population. Where longer-lived and shorter-lived hosts can infect one another (and thus all share the same risk of infection), selection will favor longer-lived individuals, to the detriment of the host population as a whole. But in metapopulations, selection can favor shorter-lived hosts that are otherwise identical to their longer-lived competitors, because the populations in which they occur will have lower incidence of disease. Under some conditions, shorter-lived hosts can even invade metapopulations of longer-lived hosts, displacing them and driving them to extinction. Our results support three general propositions. First, an organism's life-history traits, and not just its resistance genes, can affect its risk of pathogen attack. Second, pathogen mediated selection may therefore influence the evolution of host life-history traits that are unrelated to resistance, per se. Third, the magnitude-and even the direction-of selection on host longevity can depend on the structure of the host population.

PMID- 29578784 TI - Investment Strategies of Breeders in Avian Cooperative Breeding Systems. AB - An individual's optimal investment in young depends partly on the number of individuals caring for the same brood. In cooperative breeders, the investment strategy of parents with helpers is variable. When parents maintain the same effort regardless of helper number, helper care is additive. When parents fully compensate for the care of helpers by decreasing their own effort, total care does not increase. A study of long-tailed tits Aegithalos caudatus showed that both parental strategies may occur within a species, depending on the number of helpers. A comparative analysis of 27 cooperative breeders was conducted to test the predictions of a graphical model that care is additive when nestling starvation is frequent and parents exhibit compensatory reductions in care when starvation is rare. Both predictions were supported. In this interspecific comparison, a species' mean group size was not associated with compensatory responses by parents. There was some evidence that males and females had different investment rules. Males tended to show compensatory reductions in care when adult survival rate was low. In contrast, while both sexes showed compensation when nestling starvation was infrequent, this association was significant only for females.

AB - The small-rodent community in northern Fennoscandia shows regular multiannual fluctuations in abundance. We analyze time series of spring and fall abundances covering 44 yr from the vole community at Kilpisjarvi, northern Finnish Lapland, which is dominated by the gray-sided vole (Clethrionomys rufocanus). Treating spring and fall abundances as variables in a bivariate time-series model, we study seasonal aspects of population regulation and thereby utilize more of the available data than in most previous analyses of rodent fluctuations. The analysis demonstrates substantial density dependence of population growth during the winter. This includes a strong direct effect of previous fall density and a strong 2-yr delayed effect of spring density. Population growth during the summer shows evidence of delayed density dependence but is generally weaker than that during the winter season. Winter regulation appears to be a crucial element in the production of multiannual cycles in this community, and we suggest that long and severe winters coupled with delayed density dependence may be a direct cause of the vole fluctuations in northern and high-elevation areas. PMID- 29578787 TI - Extrinsic Modification of Vertebrate Sex Ratios by Climatic Variation. AB - Evidence for the influences of climate on early development, maternal condition, and offspring viability in terrestrial vertebrates suggests that climatic change has the potential to induce variation in offspring sex ratios in such organisms. Using long-term data at individual and population levels, we investigated the influence of global climatic variation, as a result of the North Atlantic Oscillation (NAO), on offspring sex ratios of red deer in Norway. The state of the NAO during the fetal development of hinds influenced the mass of their sons, but not daughters, and increasingly warmer and snowy winters led to increasingly male-biased offspring sex ratios, independently of changes in the mean age of hinds. Moreover, hinds that were themselves born following warm, snowy winters were smaller as adults, produced significantly lighter sons, and tended to produce more sons than hinds born following cold, dry winters. In light of the fact that these observations defy explanation according to previous hypotheses of adaptive modification of offspring sex ratios, we present the extrinsic modification hypothesis, which suggests that sex ratios may evolve in variable environments through natural selection independently of maternal strategies of sex allocation.

AB - Interspecific killing among mammalian carnivores is common in nature and accounts for up to 68% of known mortalities in some species. Interactions may be symmetrical (both species kill each other) or asymmetrical (one species kills the other), and in some interactions adults of one species kill young but not adults of the other. There is a positive significant relationship between the body masses of solitary killer species and body masses of their victim species, and grouping species kill larger victims than solitary species. Interactions and consumption of the victim appear more common when food is scarce or disputed. In response to killers, victim species may alter their use of space, activity patterns, and form groups. Consequences of interspecific killing include population reduction or even extinction, and reduction and enhancement of prey populations, and may therefore have important implications for conservation and management of carnivores and their prey. PMID- 29578791 TI - Predicting Plant Migration Rates in a Changing World: The Role of Long-Distance Dispersal. AB - Models of plant migration based on estimates of biological parameters severely underestimate the rate of spread when compared to empirical estimates of plant migration rates. This is disturbing, since an ability to predict migration and colonization rates is needed for predicting how native species will distribute themselves in response to habitat loss and climate change and how rapidly invasive species will spread. Part of the problem is the difficulty of formally including rare long-distance dispersal events in spread models. In this article, we explore the process of making predictions about plant migration rates. In particular, we examine the links between data, statistical models, and ecological predictions. We fit mixtures of Weibull distributions to several dispersal data sets and show that statistical and biological criteria for selecting the most appropriate statistical model conflict. Fitting a two-component mixture model to the same data increases the spread-rate prediction by an average factor of 4.5. Data limit our ability to fit more components. Using simulations, we show that a small proportion (0.001) of seeds moving long-distances (1-10 km) can lead to an order of magnitude increase in predicted spread rate. The analysis also suggests that most existing data sets on dispersal will not resolve the problem; more effort needs to be devoted to collecting data on long-distance dispersal. Although dispersal had the strongest effect on the predicted spread rate, we showed that dispersal interacts strongly with plant life history, disturbance, and habitat loss in influencing the predicted rate of spread. The importance of these interactions means that an approach that integrates local and long-distance dispersal with plant life history, disturbance, and habitat availability is essential for predicting migration rates. PMID- 29578792 TI - A Minimal Model for Forest Fire Regimes. AB - We show in this article how the characteristics of fire recurrence in forests can be theoretically derived from simple information concerning forest morphology. The task is accomplished by means of a minimal model encapsulating a few assumptions on the interactions between overstory and understory species and on the mechanisms of fire development and transmission. The main difference with other models for fire prediction and simulation is that, here, fire is an endogenous variable with purely deterministic dynamics. Nevertheless, the analysis shows that fire recurrence can be chaotic for parameter values corresponding to Mediterranean forests. By contrast, the model shows that boreal forests and savannas have the tendency to experience periodic fires. These general results are in agreement with the studies carried out on many different forests in this century. PMID- 29578793 TI - Demographic Stochasticity and Social Mating System in the Process of Extinction of Small Populations: The Case of Passerines Introduced to New Zealand. AB - Underlying the many causes of extinction of small populations is the random fate of each constituent individual or, in other words, demographic stochasticity. Demographic stochasticity is inherent to any demographic process, regardless of the environment, and its strength increases as population size gets smaller. In particular, random fluctuations in the proportion of males and females and the way they pair for reproduction (i.e., the social mating system) are usually neglected. To assess the potential importance of demographic stochasticity to the extinction process, a two-sex model with an explicit mating system was built. Extinction probabilities computed via Monte Carlo simulation were compared to real data, the case of passerines introduced to New Zealand a century ago. This minimal model of extinction allowed assessment of the importance of the mating system in the colonization process. Monogamous mating led to a higher extinction risk than did polygynous mating. Demographic uncertainty imposes high extinction probabilities on short-lived bird species as compared to long-lived bird species. Theoretical results for two-sex models are provided. PMID- 29578794 TI - Sex Roles Are Not Always Reversed When the Potential Reproductive Rate Is Higher in Females. AB - Sex roles were examined in a cardinalfish, Apogon notatus, in which males alone mouthbrood the eggs received from a single female. Before spawning, a male and female formed a pair, within which the female is more active in courtship and attacks against conspecifics. Females had a higher potential for reproduction and on average produced more than twice as many clutches as those mouthbrooded by a male in a season by changing mates after spawning. Animals in which mating competition is more intense among females and, ultimately, sexual selection is more strongly acting on females are defined as sex-role reversed. Sex-role reversal is expected where the operational sex ratio (OSR) is female biased. In A. notatus, however, the OSR was male biased throughout the breeding season. This was due primarily to a higher mortality in females. The theory predicts that sexual selection operates more strongly on the sex toward which the OSR is biased. The facts that the variance in reproductive success was greater in males and the males developed a sexual trait suggest that sexual selection is acting more strongly on males than on females. Accordingly, this fish is not sex-role reversed. PMID- 29578795 TI - An Improved Procedure for Testing the Effects of Key Innovations on Rate of Speciation. PMID- 29578796 TI - El Nino-Southern Oscillation-Driven Rainfall Variability and Delayed Density Dependence Cause Rodent Outbreaks in Western South America: Linking Demography and Population Dynamics. AB - It is well known that some rodent populations display dramatic density fluctuations in semiarid regions of western South America after the unusual rainfall levels associated with El Nino-southern oscillation (ENSO) disturbances. These correlated phenomena have led some ecologists to believe that rodent outbreaks are determined solely by density-independent factors (e.g., rainfall regime). However, demographic studies have detected strong delayed density dependent effects in one of the most irruptive rodent species, the leaf-eared mouse Phyllotis darwini. We tested the effects of rainfall and delayed density dependent factors by constructing a structured model based on demographic data estimated from a capture-mark-recapture study of this species in Chile. A model including both rainfall and delayed density-dependent effects predicts the observed population dynamics rather accurately over a 10-yr period. Interestingly, small changes in model parameters result in large changes in model dynamics, which strongly suggests that local variations in demographic features are important in explaining the asynchronous pattern in outbreak occurrences. These findings suggest that inextricably intertwined endogenous and exogenous forces cause rodent outbreaks in western South America. The former are characterized by delayed nonlinear feedbacks, whereas the latter are characterized by the positive effects of the El Nino phases and the negative effects of the La Nina phases of the ENSO disturbance. PMID- 29578797 TI - How Do Grazers Achieve Their Distribution? A Continuum of Models from Random Diffusion to the Ideal Free Distribution Using Biased Random Walks. AB - A conceptual model is described for generating distributions of grazing animals, according to their searching behavior, to investigate the mechanisms animals may use to achieve their distributions. The model simulates behaviors ranging from random diffusion, through taxis and cognitively aided navigation (i.e., using memory), to the optimization extreme of the Ideal Free Distribution. These behaviors are generated from simulation of biased diffusion that operates at multiple scales simultaneously, formalizing ideas of multiple-scale foraging behavior. It uses probabilistic bias to represent decisions, allowing multiple search goals to be combined (e.g., foraging and social goals) and the representation of suboptimal behavior. By allowing bias to arise at multiple scales within the environment, each weighted relative to the others, the model can represent different scales of simultaneous decision-making and scale dependent behavior. The model also allows different constraints to be applied to the animal's ability (e.g., applying food-patch accessibility and information limits). Simulations show that foraging-decision randomness and spatial scale of decision bias have potentially profound effects on both animal intake rate and the distribution of resources in the environment. Spatial variograms show that foraging strategies can differentially change the spatial pattern of resource abundance in the environment to one characteristic of the foraging strategy.

AB - The present study examined the bidirectional relation between family functioning and attention-deficit/hyperactivity disorder (ADHD) symptoms across the preschool years. Participants included 197 (110 boys) 3-year-old children (M = 44.14 months, SD = 3.43; 60% White) with and without behavior problems and their parents who took part in a 3-year longitudinal study. Parenting, parent psychopathology, life stress, and child symptoms were assessed annually from ages 3 to 6. Cross-lagged models provided evidence for both parent and child effects for mothers. In particular, greater maternal overreactive parenting and life stress were predictive of more child ADHD symptoms, and greater child ADHD symptoms significantly predicted greater maternal life stress and depressive symptoms and lower warmth, controlling for child oppositional defiant disorder and parent ADHD symtoms. Child effects were evident for fathers' depression and life stress, but these did not remain controlling for paternal ADHD symptoms. Findings suggest that targeting child ADHD symptoms, maternal overreactive parenting, and maternal stress each hold promise for attenuating the negative mutual influence of child ADHD symptoms and family functioning over time.

PMID- 29578801 TI - Problems With Reliability of Speech Variables for Use in Quality Registries for Cleft Lip and Palate-Experiences From the Swedish Cleft Lip and Palate Registry. AB - OBJECTIVE: To test the reliability of the speech data in the Swedish quality registry for cleft lip and palate. DESIGN: Retrospective study. SETTING: Primary care university hospital. PARTICIPANTS: Ninety-four children born with cleft palate with or without cleft lip between 2005 and 2009 who had been assessed and registered in the quality registry at the age of 5 years. MAIN OUTCOME MEASURES: Data in the registry on percent oral consonants correct, percent oral errors, percent nonoral errors, perceived velopharyngeal function (PVPF), and intelligibility were compared with results based on reassessments by 3 independent raters from audio recordings. Agreement was calculated by the intraclass correlation coefficient (ICC), quadratic weighted kappa, and percentage agreement. RESULTS: Absolute agreement calculated by average measures ICC for percent oral consonants correct, percent oral errors, and percent nonoral errors was above >0.90. Single measures ICC for percent oral consonants correct was 0.82, for percent oral errors 0.69, and for percent nonoral errors 0.83. The kappa coefficient for PVPF was 0.5 to 0.59 and for intelligibility 0.65 to 0.77. Exact percentage agreement for PVPF was 33% and for intelligibility 47.8%. CONCLUSIONS: The data on oral consonants correct and nonoral errors in the quality registry seem to be reliable. The data on oral errors, PVPF, and intelligibility should be interpreted with caution. If differences among treatment centers are detected, one should go back and examine the collected raw data before drawing any definitive conclusions about treatment outcome. PMID- 29578802 TI - Comparative Analysis of Three-Dimensional Nasal Shape of Casts from Patients With Unilateral Cleft Lip and Palate Treated at Two Institutions Following Rotation Advancement Only (Iowa) or Nasoalveolar Molding and Rotation Advancement in Conjunction With Primary Rhinoplasty (New York). AB - OBJECTIVES: To compare 3-dimensional nasal symmetry in patients with UCLP who had either rotation advancement alone or nasoalveolar molding (NAM) followed by rotation advancement in conjunction with primary nasal repair. DESIGN: Pilot retrospective cohort study. MATERIALS AND METHODS: Nasal casts of 23 patients with UCLP from 2 institutions were analyzed; 12 in the rotation advancement only group (Iowa) and 11 in the NAM, rotation advancement with primary nasal repair group (New York). Casts from patients aged 6 to 18 years were scanned using the 3Shape scanner and 3-dimensional analysis of nasal symmetry performed using 3dMD Vultus software, Version 2507, 3dMD, Atlanta, GA. Cleft and noncleft side columellar height, nasal dome height, alar base width, and nasal projection were linearly measured. Inter- and intragroup analyses were performed using t tests and paired t tests as appropriate. RESULTS: A statistically significant difference in mean-scaled 3-dimensional asymmetry index was found between groups with group 1 having a larger measure of asymmetry (4.69 cm3) than group 2 (2.56 cm3; P = .02). Intergroup analysis performed on the most sensitive linear measure, alar base width, revealed significantly less asymmetry on average in group 2 than in group 1 ( P = .013). CONCLUSION: This study suggests the NAM followed by rotation advancement in conjunction with primary nasal repair approach may result in less nasal asymmetry compared to rotation advancement alone. PMID- 29578803 TI - Opioid Sparing in Cleft Palate Surgery. AB - OBJECTIVE: This study aimed to determine whether intraoperative acetaminophen was able to decrease opioid consumption, pain scores, and length of stay while increasing oral intake in cleft palate surgery. DESIGN/SETTING/PATIENTS: One hundred consecutive patients with cleft palate who underwent a von Langenbeck or 2-flap palatoplasty and intravelar veloplasty at a tertiary medical center by the 2 senior authors from 2010 to 2015 were reviewed. INTERVENTIONS: Three intraoperative treatment groups were analyzed: intravenous (IV) acetaminophen, per rectal (PR) acetaminophen, and no acetaminophen. All patients received long acting local anesthesia infiltration before incision. Additionally, all patients were admitted overnight and given weight-based per oral (PO) acetaminophen and oxycodone and IV morphine as needed based on pain scores. OUTCOMES MEASURED: The study outcomes included pain scores, opioid requirement, length of stay, and oral intake. RESULTS: The treatment groups were comprised of 40 patients who received IV acetaminophen, 22 PR acetaminophen, and 35 none. Concerning demographic data, there was no statistical difference between treatment groups. There was no statistically significant difference for opioid intake, although both IV and PR acetaminophen groups had decreased pain scores ( P = .029). There was no difference in oral intake ( P = .13) or length of stay ( P = .31) between treatment groups. CONCLUSION: In this study, intraoperative administration of acetaminophen was associated with decreased pain scores, but no opioid-sparing effect. As other studies have shown an opioid-sparing effect with postoperative acetaminophen, we recommend withholding the intraoperative dose and beginning therapy in the immediate postoperative period. PMID- 29578804 TI - Modifications in Presurgical Nasoalveolar Molding Treatment of Bilateral Cleft Lip and Palate Patients With Severely Malpositioned Premaxillae. AB - OBJECTIVE: The aim of this study was to evaluate a modified presurgical nasoalveolar molding (PNAM) treatment for patients with bilateral cleft lip and palate (BCLP) with severely malpositioned premaxillae. SETTING: This study was conducted at the Faculty of Dentistry, Department of Orthodontics, Ege University, Bornova, Izmir, Turkey. METHOD: Retention arms were manufactured using a mold that we developed, and prefabricated retraction apparatuses were applied to the plaster model obtained from the patient. During the acrylic curing process, the flanges of the appliances were elongated into the sulcus without including the premaxilla. The premaxilla was aligned with the midline with an elastic band system, and the lip hanger was constructed with 0.023-in stainless steel wire. Elastic bands were stretched between the retraction apparatuses and the lip hanger based on the desired force. Nasal stents were added to the retention arms when the cleft width was reduced to less than 6 mm. CONCLUSION: The modified PNAM treatment enabled faster derotation of the premaxilla and earlier initiation of retraction. The prefabricated retraction apparatus and retention arm provided efficient PNAM for patients with BCLP. PMID- 29578805 TI - Diagnosis and Innovative Multidisciplinary Management of Hallermann-Streiff Syndrome: 20-Year Follow-Up of a Patient. AB - Hallermann-Streiff syndrome (HSS) is a rare congenital disorder that mainly affects head and face development. We described the different patterns of the disease throughout the whole growth period and provided innovative treatment steps. Indeed, early genioplasty and dental implantation before growth completion were performed. These steps allowed to improve facial growth and to provide orthodontic anchorage, respectively. Complementary orthognathic surgery achieved satisfactory occlusion and refined aesthetics. We believe such an approach could be considered as a relevant treatment modality to complete multidisciplinary care in patients with HSS. PMID- 29578806 TI - Improved Early Cleft Lip and Palate Complications at a Surgery Specialty Center in the Developing World. AB - OBJECTIVE: To evaluate complication rates following cleft lip and cleft palate repairs during the transition from mission-based care to center-based care in a developing region. PATIENTS AND DESIGN: We performed a retrospective review of 3419 patients who underwent cleft lip repair and 1728 patients who underwent cleft palate repair in Guwahati, India between December 2010 and February 2014. Of those who underwent cleft lip repair, 654 were treated during a surgical mission and 2765 were treated at a permanent center. Of those who underwent cleft palate repair, 236 were treated during a surgical mission and 1491 were treated at a permanent center. SETTING: Two large surgical missions to Guwahati, India, and the Guwahati Comprehensive Cleft Care Center (GCCCC) in Assam, India. MAIN OUTCOME MEASURE: Overall complication rates following cleft lip and cleft palate repair. RESULTS: Overall complication rates following cleft lip repair were 13.2% for the first mission, 6.7% for the second mission, and 4.0% at GCCCC. Overall complication rates following cleft palate repair were 28.0% for the first mission, 30.0% for the second mission, and 15.8% at GCCCC. Complication rates following cleft palate repair by the subset of surgeons permanently based at GCCCC (7.2%) were lower than visiting surgeons ( P < .05). CONCLUSIONS: Our findings support the notion that transitioning from a mission-based model to a permanent facility-based model of cleft care delivery in the developing world can lead to decreased complication rates. PMID- 29578807 TI - Comparison of the Basal View and a Previously Standardized Cleft Lip Rating Scale. AB - OBJECTIVES: Numerous scales assessing the aesthetics of cleft lip repair exist. Most, including the Asher-McDade scale, use frontal and lateral views, while neglecting a basal view. We believe this view is important for properly assessing the aesthetics of repair. In this study, we evaluate the basal view in comparison to the Asher-McDade scale. METHODS: This scale was based on progressive columellar shortening and alar flaring/slumping. A panel of 4 plastic surgeons applied the basal and Asher-McDade scales to pictures of patients with repaired unilateral cleft lip in 56 multiethnic participants aged 5 years to 18 years; images were scored from 1 to 5 (best). Statistical analysis was done via Spearman correlation. RESULTS: Scores from plastic surgeons correlated strongly for each view. There was moderate correlation for the basal view with both nasal form and deviation scores ( P < .05). As expected, there were no strong correlations between the basal view and vermillion border or profile. DISCUSSION: The Asher McDade scale has been used to evaluate cleft lift repairs but is limited due to its subjective nature. The basal view scale grades these repairs by using a scale of progressive columellar shortening and alar flaring/slumping, which provides an opportunity for quantification and standardization. Our results show that the basal view correlates with the Asher-McDade scale among raters, thus providing an objective and validated measure of cleft lip repair. PMID- 29578808 TI - Characteristics of dementia patients who described or did not describe the relationship between two people on the COGNISTAT speech sample. AB - Speech sample of Cognitive Status Examination (COGNISTAT) is a task in which examinees freely talk about what is happening in a presented picture. We investigated whether there are differences in the characteristics between patients who described or did not describe the relationship between two people in the speech sample based on age, gender, cognitive dysfunction, and type of dementia (Alzheimer's disease and dementia with Lewy bodies). The participants were 60-year-old or older patients diagnosed with Alzheimer's disease or dementia with Lewy bodies who undertook the Mini-Mental State Examination (MMSE) and COGNISTAT at a general hospital specialized in care for the elderly. MMSE and COGNISTAT were performed by a female clinical psychologist in all patients. In a stepwise logistic regression analysis using the two groups (description and no description groups) as a response variable, and the age, gender, diagnosis, MMSE score, and score of each COGNISTAT subtest as explanatory variables, the MMSE score (OR = 1.09; 95% CI [1.03, 1.15]) and gender (OR = 1.79; 95% CI [1.09, 2.93]) factors were extracted. These results indicated that patients with severer overall cognitive dysfunction and male patients were unlikely to describe the relationship between two people in a speech sample. PMID- 29578809 TI - Feasibility and Acceptability of the Gerontological Personality Disorders Scale (GPS) in General Practice: A Mixed Methods Study. AB - Although the Gerontological Personality Disorders Scale (GPS) can aid in detecting personality disorders (PDs) in older adults in general practice, its availability does not guarantee its use. This study therefore aimed to examine the feasibility and acceptability of the GPS from an older adult, informant, and professional perspective. A convergent parallel mixed methods study was conducted. Qualitative data were collected through semistructured interviews with four general practitioners and four nurse practitioners and were analyzed thematically. Quantitative data were collected through a 5-item questionnaire completed by 329 older adults and 329 informants. The thematic analysis revealed five major themes regarding feasibility and acceptability according to the professionals: taboo to ask intimate questions, quite unfamiliar with these disorders, assets, PDs are a topic of interest in general practice, and preconditions. Descriptive statistics showed that most older adults and informants found the GPS items to be clearly phrased, easy to understand, and nonconfrontational or not unpleasant to answer. The GPS is a feasible and acceptable instrument for detecting PDs in older adults in general practice. Educating professionals about PDs in older adults and the GPS is important prior to its use in daily practice and might further increase its acceptability. PMID- 29578810 TI - Understanding Attachment Transitions Through the Lived Experiences of Young Black Gay and Bisexual Men. AB - We conducted a mixed-methods study to identify factors that influence transitions in attachment style between childhood and adulthood among 28 young Black gay and bisexual men (YBGBM) in the United States. We used a phenomenological approach to data integration, with the major component to the results being garnered from the qualitative interviews. We organized our results by four attachment transition groups: stable secure (secure attachment in childhood and young adulthood), stable insecure (insecure attachment in childhood and young adulthood), secure to insecure (secure in childhood and insecure in adulthood) and insecure to secure (insecure in childhood and secure in adulthood). Within each of the typologies, two major themes emerged: social support and religion. Generally, transitions from secure to insecure attachment were related to experiences of perceived rejection by a parental figure during adolescence that corresponded with sexual orientation disclosure. Transitions from insecure to secure attachment appeared to be related to the absence of an attachment figure early in life, but with the acquisition of an attachment figure during early to late adolescence. The findings from our study suggest a need for attachment-based approaches to social support interventions, as well as for an increased understanding of social and cultural factors that impact attachment changes among practitioners who use attachment-based therapy models for YBGBM. PMID- 29578811 TI - The Validity of the Canadian Occupational Performance Measure (COPM) When Used in a Sub-Acute Rehabilitation Setting with Older Adults. AB - This study investigated the validity of the Canadian Occupational Performance Measure (COPM) when included as one of the scales used by therapists with older adults on an inpatient sub-acute rehabilitation setting. Quantitative data from 36 participants in a sub-acute rehabilitation setting was obtained via the COPM, the Functional Independence Measure (FIM) and the Short Form 36 Health Survey (SF 36) using a pre-post methodology. Pearson's r correlations and linear regression analyses were computed. The COPM Performance admission score was significantly correlated with the FIM Total and FIM Physical admission scores (p <.05) while the COPM Satisfaction admission score was significantly correlated with the FIM Total and FIM Physical admission scores (p <.05). The COPM Performance discharge score was significantly associated with the FIM Total, FIM Physical, and SF-36 Physical Health discharge scores (p <.01) while the COPM Satisfaction discharge scores was significantly associated with the FIM Total, FIM Physical, and SF-36 Physical Health discharge scores (p <.01) respectively. Linear regression analyses determined that the COPM's Performance admission score uniquely explained 8.4% of the SF-36 Physical Health discharge score's total variance (p <.05). The results contribute to the COPM's evidence base, supporting its convergent validity and predictive validity. PMID- 29578812 TI - Palestinian Nurses' and Doctors' Perceptions and Practices Regarding the Prevention of Injuries to Children in the Home: An Explorative Qualitative Study. AB - Unintentional injuries are a growing global public health problem that causes mortality, morbidity, and disability among children. These injuries are common among under-fives and form a significant burden on healthcare systems, particularly in low- and middle-income countries. Nurses and doctors have a major role to play in the prevention of home injuries, as expressed in many international reports. In Palestine, there is a paucity of research in this area. Therefore, this study aims to explore nurses' and doctors' perceptions and practices regarding the prevention of home injuries among children aged under five years. A qualitative approach was followed, whereby semi-structured interviews were undertaken with 24 nurses and doctors who worked with children in a primary health care setting. The derived data were analyzed using thematic analysis. This study found that most of the nurses and doctors who were interviewed reported positive attitudes toward working on this topic; the majority of them attempted to work on injury prevention. Nevertheless, they needed further support to fulfil this potential role, as they faced many barriers in their daily practice in this area. Policy makers could potentially take advantage of this attitude and support them by providing training, resources, and time for them to implement this role.

PMID- 29578814 TI - Mechanisms of Phytonutrient Modulation of Cyclooxygenase-2 (COX-2) and Inflammation Related to Cancer. AB - The link between chronic inflammation and cancer involves cytokines and mediators of inflammatory pathways. Cyclooxygenase-2 (COX-2), a key enzyme in fatty acid metabolism, is upregulated during both inflammation and cancer. COX-2 is induced by pro-inflammatory cytokines at the site of inflammation and enhanced COX-2 induced synthesis of prostaglandins stimulates cancer cell proliferation, promotes angiogenesis, inhibits apoptosis, and increases metastatic potential. As a result, COX-2 inhibitors are a subject of intense research interest toward potential clinical applications. Epidemiological studies highlight the potential benefits of diets rich in phytonutrients for cancer prevention. Plants contain numerous phytonutrient secondary metabolites shown to modulate COX-2. Studies have shown that these metabolites, some of which are used in traditional medicine, can reduce inflammation and carcinogenesis. This review describes the molecular mechanisms by which phytonutrients modulate inflammation, including studies of carotenoids, phenolic compounds, and fatty acids targeting various inflammation-related molecules and pathways associated with cancer. Examples of pathways include those of COX-2, mitogen-activated protein kinase kinase kinase, mitogen-activated protein kinase, pro-inflammatory cytokines, and transcription factors like nuclear factor kappa B. Such phytonutrient modulation of COX-2 and inflammation continue to be explored for applications in the prevention and treatment of cancer.

PMID- 29578816 TI - The Effect of Evidence-Based Nutrition Clinical Care Pathways on Nutrition Outcomes in Adult Patients Receiving Non-Surgical Cancer Treatment: A Systematic Review. AB - Nutritional decline associated with non-surgical cancer treatment has been well documented. The implementation of an evidence-based nutrition care pathway is one approach suggested to improve the nutrition outcomes of this group of patients. We aimed to systematically review published original research to determine whether evidence-based nutrition clinical care pathways, as compared with usual care, improve outcomes for patients receiving non-surgical cancer treatment. The review was registered with PROSPERO (CRD42017048816) and followed PRISMA guidelines. The search strategy was conducted in four databases, and supplemented by an internet search, from inception to October 2016. Study quality was assessed using the Quality Criteria Checklist for Primary Research. Results were synthesized descriptively. Six reports of five studies formed the final library with a range of interventions and control practices investigated across several diagnostic groups. Nutrition outcomes were reported using multiple approaches with either no effect, or in favor of the clinical pathway intervention. Risk of bias was low in two studies with some risk in the remaining three studies. It was not possible to determine whether the effect on nutritional outcomes was attributable to care pathway implementation. The need to extend the evidence base through high-quality clinical trials was evident. PMID- 29578817 TI - A Dyadic Approach to Pornography Use and Relationship Satisfaction Among Heterosexual Couples: The Role of Pornography Acceptance and Anxious Attachment. AB - The majority of research on pornography use within committed relationships has found such use to be associated with negative outcomes. However, given the variability in pornography use among couples, the current study sought to examine moderators in the association between pornography use and relationship satisfaction in a large sample of heterosexual matched-paired couples (N = 6,626). Actor-partner interdependence models (APIMs) revealed that for men who are more anxiously attached, more pornography use is associated with higher relationship satisfaction; whereas for women who are more anxiously attached, more pornography use is associated with lower relationship satisfaction. For men who are more accepting of pornography, more pornography use is associated with more relationship satisfaction; however, for men who are less accepting of pornography, more pornography use is associated with less relationship satisfaction. There was little difference in relationship satisfaction at differing levels of pornography use for women who are high in pornography acceptance. For women who are low in pornography acceptance, pornography use is associated with less relationship satisfaction. Results are discussed and recommendations for practitioners are made through the lens of symbolic interaction theory. PMID- 29578818 TI - Barriers and Strategies to Engaging Our Community-Based Preceptors. AB - ISSUE: This article, from the "To the Point" series that is prepared by the Association of Professors of Gynecology and Obstetrics Undergraduate Medical Education Committee, is a review of commonly cited barriers to recruiting and retaining community-based preceptors in undergraduate medical education and potential strategies to overcome them. EVIDENCE: Community-based preceptors have traditionally served as volunteer, nonsalaried faculty, with academic institutions relying on intrinsic teaching rewards to sustain this model. However, increasing numbers of learners, the burdens of incorporating the electronic medical record in practice, and increasing demands for clinical productivity are making recruitment and retention of community-based preceptors more challenging. IMPLICATIONS: General challenges to engaging preceptors, as well as those unique to women's health, are discussed. Potential solutions are reviewed, including alternative recruitment strategies, faculty development to emphasize efficient teaching practices in the ambulatory setting, offers of online educational resources, and opportunities to incorporate students in value added roles. Through examples cited in this review, clerkship directors and medical school administrators should have a solid foundation to actively engage their community-based preceptors. PMID- 29578819 TI - Effortful Control and Interpersonal Behavior in Daily Life. AB - The Cognitive-Affective Processing System (CAPS) was used to examine effortful control (EC) as a moderator of daily interpersonal behavior. Participants (N = 240) were nonclinical young adults who completed a 7-day event-contingent experience sampling study of interpersonal perception and affect. Multilevel linear models indicated that EC moderated within-person covariation of interpersonal warmth and affect activation; high EC individuals reported greater momentary warm behaviors when perceiving others as affectively activated. EC also amplified between-person covariation of interpersonal warmth between self and others; high EC individuals generally responded to perceptions of another's warmth with a greater degree of warm behavior. Varying levels of EC predict responses to interpersonal perceptions and affect in daily life, suggesting an important dimension for interpersonal functioning. PMID- 29578820 TI - Effect of applying consistent pressure to the stationary and the moving arm on measurement reliability of glenohumeral internal rotation range of motion. AB - OBJECTIVES: The aim of this study was to determine the inter-rater reliability of glenohumeral internal rotation (GIR) range of motion (ROM) and pressure measurements among four measurement methods: (1) Manual stabilization of the humeral head and coracoid process (MSHC) without applying consistent pressure (ACP) to both the stationary and the moving arms (BSaMA); (2) MSHC with ACP to the moving arm; (3) MSHC with ACP to the stationary arm; and (4) MSHC with ACP to BSaMA. DESIGN: Test-retest analyses. PARTICIPANTS: 39 subjects with GIR deficit. MAIN OUTCOME MEASURES: GIR ROM and pressure were measured on the stationary or moving arm by four examiners using the Clinometer application and a pressure biofeedback unit. RESULTS: GIR ROM measurement with MSHC and ACP to the moving arm resulted in the lowest intra-class correlation coefficient (ICC = .43); the ICC for MSHC without ACP to BSaMA was .54; that for MSHC with ACP to the stationary arm was .77; and that for MSHC with ACP to BSaMA was highest, at .81. CONCLUSION: MSHC with ACP to both arms leads to reliable GIR ROM measurement in a clinical setting. PMID- 29578821 TI - Personal Income and Substance Use among Emerging Adults in the United States. AB - BACKGROUND: Taxation and other policy measures have been implemented across the United States to curb the accessibility of substance use, especially among youth. While the inverse relationship between price and youth consumption is well known, available research on youth earned income and substance use is sparser, particularly among emerging adults. OBJECTIVES: We examined the association between emerging adult past-year personal income and 30-day substance use. METHODS: We analyzed data from Wave 5 (n = 2,202) of the NEXT Generation Health Study, an annual survey study administered to a nationally representative sample of emerging adults in the U.S. Wave 5 (mean age = 20.28 years, SE = 0.02 years) was administered during the 2013-2014 academic year. After grouping participants into five levels of self-reported, pre-tax personal income, we used binomial logistic regression to examine the association between personal income and cigarette smoking, marijuana use, alcohol use, and heavy episodic drinking (HED). RESULTS: In unadjusted models, those at certain levels of higher past-year income were more likely to smoke cigarettes, consume alcohol, or engage in HED at least once in the past 30 days. Several associations remained significant after controlling for covariates. Most associations were no longer significant after including perceived peer norms as additional covariates. Personal income was not associated with 30-day marijuana use in unadjusted or adjusted models. Conclusions/Importance: Higher earned income may provide emerging adults greater economic access to cigarettes and alcohol, but the association might be partly attenuated by social factors, particularly perceived peer norms. PMID- 29578822 TI - Pharmacotherapy for chronic non-specific low back pain: current and future options. AB - INTRODUCTION: Low back pain is associated with a large burden-of-illness. It is responsible for the most years lived with disability as compared with any other medical condition. A comprehensive overview of the evidence on pharmacological treatment options for chronic low back pain is lacking. This review evaluates the evidence for the benefits and risks of currently available pharmacological treatments for chronic low back pain. Areas covered: The authors focus on the recent (Cochrane) systematic reviews and meta-analyses of randomized clinical trials covering paracetamol (acetaminophen), NSAIDs, muscle relaxants, antidepressants, anticonvulsants, opioids, and other (new) drugs. Expert opinion: The overall impression of the efficacy of pharmacological treatments for patients with chronic low back pain is rather sobering. The effects on pain reduction and improvement of function are commonly small to moderate and short lasting when compared to placebo. At the same time, the various types of drugs are not without side-effects. This holds especially true for serious side-effects associated with (prolonged) use of strong opioids. Future studies on patients with chronic back pain should aim to identify subgroups of patients with good response to specific pharmacological treatment to facilitate personalized care. PMID- 29578823 TI - Possible Allergenic Role of Tropomyosin in Patients with Adverse Reactions after Fish Intake. AB - In a recent case report, patient's anti-fish tropomyosin IgE was associated with gastrointestinal symptoms. We aimed to demonstrate on a wider scale that the panallergen tropomyosin should not be limited to invertebrate species and that clinically relevant reactions could be elicited by vertebrate tropomyosin. On the whole, 19 patients with adverse reactions after fish intake and showing negative skin tests with commercial fish extracts were included. Fish tropomyosin was recognized by 10/19 patients' IgE by immunoblotting. All patients with gastrointestinal complaints after fish intake (6/6) showed an IgE band matching with tropomyosin. Cod, albacore, and swordfish tropomyosins were recognized by most patients although 3/10 patients did not claim adverse reactions to these fish species. Immunoblotting with a battery of antigens from different fish species have a high yield of positivity at a band matching with tropomyosin molecular weight, even if they have not been claimed to be causative agents of symptoms. Tropomyosin is therefore a good candidate to be investigated as a clinically relevant fish allergen in patients who report adverse reactions after fish intake. PMID- 29578824 TI - Probing Water Mobility in Human Dentine with Neutron Spectroscopy. AB - The aim of this study was to investigate hydrogen mobility within innate and demineralized human dentine. Dentine sections from extracted human molars, demineralized or not, were analyzed by combining neutron spectroscopy with thermal analysis. For the thermal analysis of the samples, differential scanning calorimetry and thermal gravimetric analysis, coupled with Fourier transform infrared spectroscopy, were performed. The hydrogen dynamics of water, collagen, and hydroxyl groups present in the samples were investigated via neutron spectroscopy. From the mass loss observed from the thermogravimetric analysis curves up to 600 degrees C, the same amount of organic content is identified in the samples. From the differential scanning calorimetry curves, a higher change in enthalpy associated with the denaturation of collagen is registered in the demineralized dentine; that is, a structural change occurs in the collagen subsequent to demineralization. Since the intensity measured by neutron spectroscopy is dominated by the signal from hydrogen, in our samples-coming mostly from the bulk-like and loosely bound water as well as from the collagen itself-higher proton mobility within the demineralized dentine was detected when compared with innate dentine. In the demineralized dentine, this proton mobility amounts to 80%, while the remaining hydrogen accounts for a combination of 1) structural hydroxyls, as a result of the incomplete dissolution of the mineral phase by acid etching, and 2) hydrogen tightly bound in the collagen structure. By combining neutron spectroscopy with the calorimetry data, our findings support the idea that hydroxyapatite protects the collagen in innate dentine. Demineralized dentine, however, acts as a sponge where free bulk-like water is trapped. PMID- 29578825 TI - Reduction of Tribocorrosion Products When Using the Platform-Switching Concept. AB - The reduced marginal bone loss observed when using the platform-switching concept may be the result of reduced amounts of tribocorrosion products released to the peri-implant tissues. Therefore, the purpose of this study was to compare the tribocorrosion product release from various platform-matched and platform switched implant-abutment couplings under cyclic loading. Forty-eight titanium implants were coupled with pure titanium, gold alloy, cobalt-chrome alloy, and zirconia abutments forming either platform-switched or platform-matched groups ( n = 6). The specimens were subjected to cyclic occlusal forces in a wet acidic environment for 24 h followed by static aqueous immersion for 6 d. The amount of metal ions released was measured using inductively coupled plasma mass spectrometry. Microscopic evaluations were performed pre- and postimmersion under scanning electron microscope (SEM) equipped with energy-dispersive spectroscopy X ray for corrosion assessment at the interface and wear particle characterization. All platform-switched groups showed less metal ion release compared with their platform-matched counterparts within each abutment material group ( P < 0.001). Implants connected to platform-matched cobalt-chrome abutments demonstrated the highest total mean metal ion release (218 ppb), while the least total mean ion release (11 ppb) was observed in the implants connected to platform-switched titanium abutments ( P <= 0.001). Titanium was released from all test groups, with its highest mean release (108 ppb) observed in the implants connected to platform-matched gold abutments ( P < 0.001). SEM images showed surface tribocorrosion features such as pitting and bands of fretting scars. Wear particles were mostly titanium, ranging from submicron to 48 um in length. The platform-matched groups demonstrated a higher amount of metal ion release and more surface damage. These findings highlight the positive effect of the platform switching concept in the reduction of tribocorrosion products released from dental implants, which consequently may minimize the adverse tissue reactions that lead to peri-implant bone loss. PMID- 29578826 TI - The Impact of Tobacco Consumption on Rural Household Expenditure and Self-rated Health Among Rural Household Members in China. AB - OBJECTIVES: To estimate how tobacco consumption affects household expenditure on other goods and services in rural China and to assess the tobacco consumption affects self-rated health among rural household members in China. METHODS: A Seemingly Unrelated Regression was used to assess the impact of tobacco consumption on rural household expenditure. To detect tobacco consumption causing heterogeneity in self-rated health among adults in rural China, this study employed a random effects generalized ordered probit model. 2010-2014 China Family Panel Studies was used for the analysis. The data set included 3,611 households and 10,610 adults in each wave. RESULTS: Tobacco consumption households assign significantly lower budget shares to food, health care, dress, and education in rural China. Moreover, self-rated health factor has a significantly positive coefficient with respect to non-smokers and ex-smokers, that is, when the individuals is a non-smoker or ex-smoker, he/ she will be more likely to report his/her health status as positive. CONCLUSIONS: The first analysis showed that tobacco consumption crowds out expenditures on food, dress, health care, and education for rural households in China, and the second analysis indicated that non-smokers and ex-smokers are more likely to report their health status as better compared with last year. The results of the present study revealed that Chinese policymakers might consider controlling tobacco consumption since tobacco control can improve not only rural household welfare but also rural household members' health status. Therefore, the tobacco tax policy and brief clinical interventions by the doctor should be implemented in rural China.

AB - The purpose of this study was to identify the level of burden and quality of life of family caregivers of stroke patients and to investigate the correlation between burden, quality of life (including physical, social, psychological, and environmental domains), age of caregivers, and the care period. A descriptive correlational cross-sectional study was performed, with a convenience sample of family caregivers (n = 30) of stroke patients in Sao Paulo, Brazil. Data were collected using a questionnaire on participants' characteristics, the Zarit Burden Interview Scale (ZBIS), and the World Health Organization Quality of Life BREF (WHOQOL-BREF) instrument. A descriptive analysis was performed, and correlations between variables were analyzed using Pearson's product-moment correlation coefficient. The average burden score on the ZBIS was 29.6, representing a moderate burden, and the average overall quality of life score on the WHOQOL-BREF was 62.06%, which indicates moderate quality of life. A significant weak negative correlation was observed between burden and environmental domains (r = -0.470; p =.009), quality of life (r = -0.414; p =.023), and physical domains (r = -0.394; p =.031). No significant correlations were found between burden and quality of life, and variables in the psychological and social domains, age of caregivers, or care period. Caregivers for stroke patients presented with moderate levels of burden and reduction in quality of life. Levels of burden correlated negatively with environmental domains, quality of life levels, and physical domains; however, these correlations were weak, indicating the possible interference of other factors. PMID- 29578828 TI - The cellular and molecular effects of the androgen receptor agonist, Cl-4AS-1, on breast cancer cells. AB - PURPOSE: The androgen receptor (AR) has attracted attention in the treatment of breast cancer. Due to the undesirable side effects of AR agonists, attempts have been undertaken to develop selective AR modulators. One of these compounds is Cl 4AS-1. This study examined this compound more closely at the cellular and molecular levels. METHODS: Three different breast cancer cell lines were utilized, namely the luminal MCF-7 cells, the molecular apocrine MDA-MB-453 cells, and the triple negative, basal MDA-MB-231 cells. RESULTS: High and significant concordance between dihydrotestosterone (DHT) and Cl-4AS-1 in regulation of gene expression in MDA-MB-453 cells was found. However, some differences were noted including the expression of AR, which was upregulated by DHT, but not Cl-4AS-1. In addition, both DHT and Cl-4AS-1 caused a similar morphological change and reorganization of the actin structure of MDA-MB-453 cells into a mesenchymal phenotype. Treatment of cells with DHT resulted in induction of proliferation of MCF-7 and MDA-MB-453 cells, but no effect was observed on the growth of MDA-MB-231 cells. On the other hand, increasing doses of Cl-4AS-1 resulted in a dose-dependent inhibition on the growth of the three cell lines. This inhibition was a result of induction of apoptosis whereby Cl-4AS 1 caused a block in entry of cells into the S-phase followed by DNA degradation. CONCLUSIONS: These results indicate that although Cl-4AS-1 has characteristics of classical AR agonist, it has dissimilar properties that may make it useful in treating breast cancer. PMID- 29578829 TI - "They Gave Me Life": Motherhood and Recovery in a Tribal Community. AB - OBJECTIVE: This study explored factors related to substance misuse and recovery among Native mothers in a Pacific Northwest tribe, focusing on motherhood as a motivating factor in seeking treatment and sustaining recovery. METHOD: Using a community-based participatory research approach, we conducted a thematic analysis of 20 in-depth interviews and one focus group (N = 12) with Native women 18 years and older living on or near the reservation. RESULTS: Qualitative findings highlighted challenges, motivations and strategies for seeking treatment and recovery in four major themes: (a) the close relationship between interpersonal violence and substance misuse; (b) traditional healing in recovery; (c) community specific challenges to recovery; and (d) the motivating role of motherhood in seeking treatment and successful recovery. CONCLUSIONS: A central finding of this work is that pregnancy and motherhood may be underexplored factors in Native women's substance use. Results support previous work suggesting that Native women are at high risk of interpersonal trauma and that trauma contributes to substance misuse. Findings offer several rich implications for treatment and recovery among Native mothers in tribal communities including the necessity of trauma-informed treatment, community and culturally-based interventions, more integration of treatment services with Child Protective Services, and drawing on motherhood as a motivation for seeking and succeeding in recovery. PMID- 29578830 TI - Mortality and Cause of Death-A 30-Year Follow-Up of Substance Misusers in Sweden. AB - BACKGROUND: This article presents a 30-year follow-up study of a cohort of 1163 substance misusers who were in inpatient treatment in the early 1980s. Data was originally collected in the Swedish Drug Addict Treatment Evaluation (SWEDATE). OBJECTIVES: The aim is to examine the overall mortality and identify causes of death in different groups based on self-reported most dominant substance misuse among those who have died during January 1984-December 2013. METHODS: SWEDATE data was linked to the National Cause of Death Register. Five mutually exclusive study groups were created based on self-reported most dominant substance misuse for the last 12 months before intake to treatment: Alcohol, Cannabis, Stimulants, Opiates, and Other. The Standardized Mortality Ratio (SMR) was calculated. RESULTS: During the follow-up, 40% died. SMR is 10.3 for women and 11.7 for men. The study groups differed regarding SMR; 13.1 in the Alcohol group, 9.2 in the Cannabis group, 9.6 in the Stimulants group, 16.7 in the Opiates group and 10.8 in the Other group. Drug related death was the most common cause of death (28% only underlying, 19% both underlying and contributing) followed by alcohol related reasons (17% vs. 9%). CONCLUSIONS: Alcohol misuse among substance abusers might have a negative impact on mortality rates. Methodological changes in how drug related deaths is registered affects the interpretation of the statistics of cause of death. Further analysis on the relation between drug related cause of death and drug misuse related death is needed. PMID- 29578831 TI - Is It Feasible and Safe to Wake Cardiac Arrest Patients Receiving Mild Therapeutic Hypothermia After 12 Hours to Enable Early Neuro-Prognostication? The Therapeutic Hypothermia and Early Waking Trial Protocol. AB - Mild therapeutic hypothermia (MTH 33 degrees C) post out-of-hospital cardiac arrest (OHCA) is widely accepted as standard of care. However, uncertainty remains around the dose and therapy duration. OHCA patients are usually kept sedated+/-paralyzed and ventilated for the first 24-36 hours, which allows for targeted temperature management, but makes neurological prognostication challenging. The aim of this study is to investigate the feasibility and safety of assessing the unconscious OHCA patient after 12 hours for early waking/extubation while continuing to provide MTH for 24 hours, and fever prevention for 72 hours by using an intravenous temperature management (IVTM) system and established conscious MTH anti-shiver regimens. This is a single center, prospective, non-randomized observational study that will compare the results of early awakening (at 12 hours) with historical controls. A total of 50 consecutive unconscious survivors of OHCA, treated with MTH, who meet the Therapeutic Hypothermia and eArly Waking (THAW) inclusion criteria will be enrolled. The patient will receive MTH by using IVTM. After 12 hours of MTH, patients will be assessed by using strict clinical criteria to determine suitability for early waking and extubation. Once awake and extubated, MTH will continue for 24 hours with skin counter-warming and anti-shiver regimen followed fever prevention up to 72 hours. All patients will have serial electroencephalogram (EEG), somatic sensory potential, and neuro-biomarkers performed on admission to intensive care unit, 6 and 12 hours, then every 24 hours until 72 hours. The study has been approved by the National Research Ethics Service, Health Research Authority. PMID- 29578832 TI - Pilot Randomized Trial of an Automated Smoking Cessation Intervention via Mobile Phone Text Messages as an Adjunct to Varenicline in Primary Care. AB - OBJECTIVE: Varenicline is a safe and effective aid to smoking cessation but most trials have involved frequent visits or intensive behavioral support unlike that typically provided in primary care. The current study examined if motivational text messages, sent via cellphone, would increase quit rates in smokers being treated with varenicline and 3 brief sessions in a family practice setting. METHODS: This study was a randomized controlled, parallel-group smoking cessation trial. Intervention group participants (n = 74) received daily motivational text messages, additional texted tips in response to keywords, and weekly study questions while control group participants (n = 76) received only weekly study questions. Both groups received individualized counseling. Self-reported non smoking and exhaled breath CO <10ppm were used to validate smoking abstinence at 3 weeks and 12 weeks. RESULTS: Overall, 30.7% (46/150) of participants were abstinent at the 12 week follow-up and the abstinence rate did not differ between groups (INT 31.1% v. CON 30.3%, p = .91). The only predictor of abstinence at 12 weeks was use of varenicline during a previous quit attempt (p = .01). Intervention group participants were more likely to rate the text messaging program as good or excellent (p < .01), to recommend a similar program to family or friends (p < .01), and to complete positive smoking cessation activities (p = .04), when compared with the control group. CONCLUSION: Although there were no differences in quit rates between the intervention and control group, intervention group participants rated the text messaging system more favorably, were more likely to recommend the program to others, and were more likely to complete positive smoking cessation activities. PMID- 29578833 TI - Program theory within policy-initiated evaluations: the Norwegian low-income family study. AB - Using as an example a project where the Norwegian Labor and Welfare Directorate developed a comprehensive model for the follow-up of low-income families, this article demonstrates the process of developing a program theory for policy initiated interventions. The data consist of interviews with program developers, political documents from early stages, and observations of the program's development. The results demonstrate that, although research inspired the program developers, the program was also the outcome of policy priorities, experiences from earlier projects, and input from the practice field. Multiple sources contributed to its relevance for the practice field, however, increasing its complexity. The program includes several intervention levels and follow-up areas and partially builds on elements found to be important across interventions. Although a program theory can be difficult to conceptualize within policy initiated interventions, it is important to articulate it prior to evaluation and, if necessary, reassess it when data have been analyzed. PMID- 29578834 TI - Adverse drug events and medication problems in "Hospital at Home" patients. AB - "Hospital at Home(HaH)" programs provide an alternative to traditional hospitalization. However, the incidence of adverse drug events in these programs is unknown. This study describes adverse drug events and potential adverse drug events in a new HaH program. We examined the charts of the first 50 patients admitted. We found 45 potential adverse drug events and 14 adverse drug events from admission to 30 days after HaH discharge. None of the adverse drug events were severe. Some events, like problems with medication administration, may be unique to the hospital at home setting. Monitoring for adverse drug events is feasible and important for hospital at home programs. PMID- 29578835 TI - The Center for Social Innovation at Boston College. AB - Established in 2011, the Center for Social Innovation at Boston College has focused on fostering "effective, sustainable social innovations that enhance social justice." the Center is committed to building research evidence that is used for changing practice and works to disseminate findings through a three channel approach: traditional research publications, convening of practitioners, and through use of media outlets. PMID- 29578837 TI - My Entrance, Her Exit. PMID- 29578836 TI - Protective effects of photobiomodulation against resistance exercise-induced muscle damage and inflammation in rats. AB - We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 +/- 10 g), 2J (215 +/- 8 g), 4J (210 +/- 9 g), and 8J (226 +/- 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1beta, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role. PMID- 29578838 TI - Reliability and Validity of Finger Strength and Endurance Measurements in Rock Climbing. AB - PURPOSE: An advanced system for the assessment of climbing-specific performance was developed and used to: (a) investigate the effect of arm fixation (AF) on construct validity evidence and reliability of climbing-specific finger-strength measurement; (b) assess reliability of finger-strength and endurance measurements; and (c) evaluate the relationship between finger flexor all-out test scores and climbing ability. METHODS: To determine the effect of AF, 22 male climbers performed 2 maximal strength and all-out tests with AF (shoulder and elbow flexed at 90 degrees ) and without AF (shoulder flexed at 180 degrees and elbow fully extended). To determine reliability, 9 male climbers completed 2 maximal strength tests with and without AF and an all-out and intermittent test without AF. RESULTS: The maximal strength test without AF more strongly determined climbing ability than the test with AF (r2 = .48 and r2 = .42 for sport climbing; r2 = .66 and r2 = .42 for bouldering, respectively). Force and time variables were highly reliable; the rate of force development and fatigue index had moderate and low reliability. The maximal strength test with AF provided slightly higher reliability than without AF (intraclass correlation coefficient [ICC] = 0.94, ICC = 0.88, respectively). However, smaller maximal forces were achieved during AF (484 +/- 112 N) than without AF (546 +/- 132 N). All-out test average force had sufficiently high reliability (ICC = 0.92) and a relationship to sport climbing (r2 = .42) and bouldering ability (r2 = .58). CONCLUSION: Finger strength and endurance measurements provided sufficient construct validity evidence and high reliability for time and force parameters. Arm fixation provides more reliable results; however, the position without AF is recommended as it is more related to climbing ability. PMID- 29578839 TI - Utilizing risk index for overdose or serious opioid-induced respiratory depression (RIOSORD) scores to prioritize offer of rescue naloxone in an outpatient veteran population: A telephone-based project. AB - BACKGROUND: Since 2014, the Department of Veterans Affairs (VA) has been working to address the ongoing opioid epidemic through opioid-education initiatives, the development of risk calculators, and other risk stratification tools. One primary focus of VA efforts has been the distribution of rescue naloxone kits to veterans at greatest risk of opioid-related adverse events. The purpose of this project was to identify primary care veterans at highest risk for serious opioid-related adverse events using the Risk Index for Overdose and Serious Opioid-Induced Respiratory Depression (RIOSORD) and offer rescue naloxone kits by telephone based outreach. RIOSORD is a risk-stratification tool developed and validated within the veteran population. METHODS: Veterans identified at highest risk of overdose or opioid-related adverse effects were contacted by telephone or letter to offer to provide a rescue naloxone kit between November 1st, 2016 and February 1st, 2017. The primary outcome of the project was the percentage of patients contacted that agreed to a naloxone prescription. Secondary outcomes included comparative efficacy of phone versus letter contact and reasons for refusal of naloxone if the offer was declined. RESULTS: Of 41 veterans targeted by this project, most were successfully reached by telephone within three attempts (92.7%, n = 38). Approximately two-thirds of those reached by telephone agreed to a prescription for rescue naloxone (n = 26, 63.4%). The veterans that requested rescue naloxone selected the nasal formulation (n = 17) over the intramuscular auto-injector (n = 9). CONCLUSIONS: This project demonstrated that telephone based outreach can be one method of distributing rescue naloxone to a high-risk patient population without requiring an in-person visit to a provider. PMID- 29578840 TI - Emotional arousal deficit or emotional regulation bias? An electrophysiological study of age-related differences in emotion perception. AB - : Background/Study context: Adult age differences in emotion processing have been attributed to age-related decline in earlier emotional perception and age-related bias in later emotional regulation. Yet, the relationship between the processes of early emotion perception and bias in emotional regulation and their influence on behavioral outcomes remains unclear. Event-related potentials (ERPs) have the temporal precision to allow for the online measure of neurophysiological activity and provide potential insight into the complex dynamics of emotion processing and aging. METHODS: ERPs were used as the primary measure to examine the hypotheses that younger adults will differ in emotional arousal and emotional bias as represented by the early P1 waveform and later P3 waveform, respectively. Thirty two younger and older adults (16 each) performed a facial emotion discrimination task in which they identified standardized angry, happy, or neutral expressions of faces from the NimStim database. RESULTS: Younger adults showed a greater P1 ERP for angry faces relative to happy faces at parietal channels, while older adults did not exhibit any emotional modulation of the P1. In contrast, both younger and older adults showed a greater late P3 ERP for angry faces compared to happy faces. CONCLUSION: The authors' results provide evidence for an age-related deficit in early emotion perception and autonomic arousal. Younger adults, but not older adults, exhibited a pattern of neurophysiological activity believed to reflect preconscious and reflexive identification of threat. Despite these age group differences in early emotion processing, younger and older adults did not exhibit differences in neurophysiological processes believed to reflect emotion regulation. PMID- 29578841 TI - Achieving body confidence for young children: Development and pilot study of a universal teacher-led body image and weight stigma program for early primary school children. AB - Negative body image attitudes develop in early childhood and there is a need for school-based resources during the early school years, but no teacher-delivered curriculum-based resources exist to mitigate these attitudes in young children. Achieving Body Confidence for Young Children (ABC-4-YC), a universal body dissatisfaction and weight stigma prevention program, was developed and then delivered in a pilot study. Fifty-one 5- to 8-year-old children completed pre- and post-intervention interviews assessing body image attitudes, and seven teachers provided feedback. Significant improvement in body esteem and positive teacher feedback were found. The results provide preliminary support for ABC-4-YC to improve children's body image attitudes, but extensive evaluation is needed. PMID- 29578842 TI - Associations of Perceived Discrimination With Impaired Functioning in a Population Sample With Psychological Distress. AB - OBJECTIVE: To test associations between perceived discrimination based on mental health status and impaired functioning in a population sample with psychological distress. METHODS: Interviews were conducted with a sample of respondents to the California Health Interview Survey with mild, moderate, or severe psychological distress. Perceived discrimination was assessed using 14 items covering four domains in which discrimination is reported: social, partner, institutional, and work. Associations of perceived discrimination scores (total score and domain scores) with impaired functioning, measured by the likelihood and number of days out of role, were estimated with statistical adjustment for demographic characteristics and serious psychological distress. RESULTS: Discrimination domain scores are significantly correlated (r ranging from .34 to .65).Total discrimination score is associated with having days out of role (OR = 1.20, 95% CI = 1.10-1.30) and with number of days out of role (5.5 days) after adjustment for demographics and psychological distress. The high correlation among the domain scores makes the attribution of association to particular domains uncertain. Removal of the effect of discrimination using model-based simulation reduces past-year days out of role by 39.4 (SE 11.3) days. CONCLUSIONS: This observational study supports the suggestion that discrimination against people with mental illness contributes to their impaired functioning in a diverse range of social roles. The results provide preliminary evidence that reduction in discrimination against people with mental illness could improve social functioning and work productivity. Correlations among domain scores make it difficult to draw conclusions about domain-specific associations. PMID- 29578843 TI - Psychosocial Services for Individuals With Serious Mental Illness/Severe Emotional Disturbance: Clinical Practice Guideline Toolkit. AB - This article presents a short, easy-to-use guideline for clinicians working with people with serious mental illness, particularly those with schizophrenia, schizoaffective disorder, delusional disorders, other psychotic disorders, or depression with significant impact on functioning, and may be of use for those working with individuals with bipolar disorder. This guideline is not meant to supplant the more detailed, excellent clinical practice guidelines that have been developed and published. Rather, the charts and explanation presented here are designed as a step-by-step tool that clinicians can use to ensure they are following the most appropriate course of action and providing the best psychosocial rehabilitation services possible for persons with these disorders. Program managers can use this tool to evaluate the processes used in their system to ensure that appropriate services are offered for the individuals in their care. This guideline is also not meant as a substitute for comprehensive training in the practice of assessment and treatment for individuals with serious mental illness. Very little detail is provided about the disorders, appropriate assessments, and interventions because clinicians providing services to people with these disorders should have received the specialized training necessary to appropriately deliver the services needed by these individuals. PMID- 29578845 TI - Negative stereotypes as motivated justifications for moral exclusion. AB - We investigated the connection between moral exclusion of outgroups and on the one hand, right-wing authoritarianism (RWA), and social dominance orientation (SDO) on the other. We assumed that both RWA and SDO would increase the tendency to place other groups out of the scope of justice. However, we also tested whether negative stereotypes about an outgroup's threatening and norm-violating misbehavior would serve as a justification for moral exclusion. These assumptions were tested in connection with Roma, Jewish, and Muslim people as target groups in the Hungarian context (N = 441). In line with our hypotheses, we found that both RWA and SDO had an indirect effect on moral exclusion mediated by negative stereotypes about the particular target group. Our findings suggested that negative stereotypes were more important legitimizing factors for RWA than for SDO. Our results highlight the benefits of interpreting the process of moral exclusion as an outcome of motivated social cognition.

AB - Despite patients referred to home health having diverse and complex needs, it is unknown how nurses develop personalized visit plans. In this qualitative descriptive study, we interviewed 26 nurses from three agencies about their decision-making process to determine visit intensity and analyzed data using directed content analysis. Following a multifactorial assessment of the patient, nurses relied on their experience and their agency's protocols to develop the personalized visit plan. They revised the plan based on changes in the patient's clinical condition, engagement, and caregiver availability. Findings suggest strategies to improve visit planning and positively influence outcomes of home health patients. PMID- 29578846 TI - Understanding complex care for older adults within Canadian home care: a systematic literature review. AB - In the context of an aging population, both the need for home care services and its complexity of care have increased in many high-income countries. Yet, the definition of what constitutes complex care is largely elusive. This systematic review examined the conceptual definition of complex care within the home care environment using several social and health science databases for research published from 2000 to 2017. Of the 25 articles and reports identified, only 16 addressed complex care specifically and included older adults, aging, and/or home care. The results showed that complex care for older adults is primarily defined from a biomedical approach focusing on chronic disease and management and less commonly from the perspective of the social determinants of health. Future studies should consider the importance of the continuum of care needs from both the biomedical and the social determinants to adequately plan and provide care for older adults. PMID- 29578847 TI - Development of Quality Indicators to Assess Oral Anticoagulant Management in Community Pharmacies for Patients with Atrial Fibrillation. AB - BACKGROUND: Few studies have evaluated the quality of oral anticoagulant management by community pharmacists. There is no complete set of quality indicators available for this purpose. OBJECTIVE: To develop a set of specific quality indicators to assess oral anticoagulant management by community pharmacists for patients with atrial fibrillation (AF). METHODS: Quality indicators were developed in 3 phases. In phase 1, potential quality indicators were generated based on clinical guidelines and a literature review. In phase 2, a modified RAND appropriateness method involving 2 rounds was implemented with 9 experts, who judged the appropriateness of quality indicators generated in phase 1 based on the extent to which they were accurate, based on evidence, relevant, representative of best practices, and measurable in community pharmacies. Phase 3 consisted of a feasibility assessment in 5 community pharmacies on 2 patients each. RESULTS: The final set included 38 quality indicators grouped into 6 categories: documentation (n = 29), risk assessment (n = 3), clinical control (n = 1), clinical follow-up (n = 15), choice of therapy (n = 11), and interaction management (n = 8). The quality indicators referred to process of care (n = 34), clinical outcomes (n = 2), or structure of care (n = 2). There were 24 quality indicators related to vitamin K antagonists (VKAs), and 17 were related to direct oral anticoagulants (DOACs). To assess quality indicators, a questionnaire was developed for completion by community pharmacists for each patient, which included 17 questions about VKA patients and 12 questions about DOAC patients. CONCLUSIONS: A first set of quality indicators is now available to assess the quality of oral anticoagulant management by community pharmacists for patients with AF.

PMID- 29578848 TI - The Additional Costs per Month of Progression-Free Survival and Overall Survival: An Economic Model Comparing Everolimus with Cabozantinib, Nivolumab, and Axitinib for Second-Line Treatment of Metastatic Renal Cell Carcinoma. AB - BACKGROUND: When considering optimal second-line treatments for metastatic renal cell carcinoma (mRCC), clinicians and payers seek to understand the relative clinical benefits and costs of treatment. OBJECTIVE: To use an economic model to compare the additional cost per month of overall survival (OS) and of progression free survival (PFS) for cabozantinib, nivolumab, and axitinib with everolimus for the second-line treatment of mRCC from a third-party U.S. payer perspective. METHODS: The model evaluated mean OS and PFS and costs associated with drug acquisition/administration; adverse event (AE) treatment; monitoring; and postprogression (third-line treatment, monitoring, and end-of-life costs) over 1- and 2-year horizons. Efficacy, safety, and treatment duration inputs were estimated from regimens' pivotal clinical trials; for everolimus, results were weighted across trials. Mean 1- and 2-year OS and mean 1-year PFS were estimated using regimens' reported OS and PFS Kaplan-Meier curves. Dosing and administration inputs were consistent with approved prescribing information and the clinical trials used to estimate efficacy and safety inputs. Cost inputs came from published literature and public data. Additional cost per additional month of OS or PFS was calculated using the ratio of the cost difference per treated patient and the corresponding difference in mean OS or PFS between everolimus and each comparator. One-way sensitivity analyses were conducted by varying efficacy and cost inputs. RESULTS: Compared with everolimus, cabozantinib, nivolumab, and axitinib were associated with 1.6, 0.3, and 0.5 additional months of PFS, respectively, over 1 year. Cabozantinib and nivolumab were associated with additional months of OS compared with everolimus (1 year: 0.7 and 0.8 months; 2 years: 1.6 and 2.3 months; respectively); axitinib was associated with fewer months (1 year: -0.2 months; 2 years: -0.7 months). The additional costs of treatment with cabozantinib, nivolumab, or axitinib versus everolimus over 1 year were $34,141, $19,371, and $17,506 higher, respectively. Everolimus had similar OS and lower costs compared with axitinib. The additional cost per month of OS was $48,773 for cabozantinib and $24,214 for nivolumab versus everolimus. The additional treatment cost with cabozantinib, nivolumab, or axitinib versus everolimus for each additional month of PFS was estimated at $21,338, $64,570, and $35,012, respectively. Over 2 years, the additional costs per additional month of OS for nivolumab and axitinib versus everolimus were similar to the 1 year analysis; for cabozantinib, the cost was lower. Results were sensitive to changes in mean OS, mean PFS, therapy duration, and drug costs estimates. CONCLUSIONS: Everolimus for second-line mRCC was associated with similar OS and lower costs compared with axitinib over 1- and 2-year horizons. The additional cost per additional month of OS and PFS associated with cabozantinib or nivolumab versus everolimus creates a metric for evaluating the cost of second-line therapies in relation to their respective treatment effects.

PMID- 29578849 TI - Disparities in Initial Oral Antidiabetic Medication Adherence Among Veterans with Incident Diabetes. AB - BACKGROUND: Medication nonadherence is a prevalent public health issue, particularly among patients with diabetes mellitus (DM), and negatively affects health outcomes. Because of the prevalence of DM among U.S. veterans, it is crucial to understand how well these patients adhere to oral antidiabetic (OAD) medication and whether certain subgroups are more likely to be nonadherent. OBJECTIVE: To assess initial OAD medication use among veterans with uncomplicated DM and determine factors associated with adherence in the first 2 years of treatment. METHODS: This was a retrospective cohort study using data from the Veterans Affairs (VA) Corporate Data Warehouse from 2002 through 2014. The first diagnosis for uncomplicated DM was determined, and then medication use was assessed following OAD initiation. OAD use was assessed by proportion of days covered (PDC) for the first 2 years of therapy using outpatient VA pharmacy records. Adherence was determined both continuously and categorically, with a PDC of >= 80% used to indicate adherence. Logistic regression was used to determine if certain patient characteristics were associated with being adherent to OADs. RESULTS: A total of 148,544 veterans with uncomplicated DM were assessed, most of whom were white, aged >= 55 years, and initiated OAD therapy on metformin. A large portion resided in the southern part of the United States. In the first year, PDC averaged 79.2% (SD = 25.9), and 63.2% were adherent to OAD therapy; however, these numbers declined in the second year, when the average PDC was 71.3% (SD = 35.8), and only 59.1% were adherent. Over the course of both years, PDC averaged 75.3% (SD = 28.4), and 50.9% were adherent. The odds of being adherent were higher among older adults and significantly lower among veterans self-identifying as either African American (OR = 0.61; 95% CI = 0.59-0.63), Native American (OR = 0.67; 95% CI = 0.61-0.75), or Hawaiian/Pacific Islander (OR = 0.84; 95% CI = 0.76-0.92) when compared with whites. Veterans who were either divorced/separated (OR = 0.86; 95% CI = 0.83-0.88) or never married (OR = 0.89; 95% CI = 0.86-0.93) also had lower odds of being initially adherent to OAD therapy compared with those who reported being married. Being nonadherent in year 1 was highly predictive of remaining nonadherent in year 2 (OR = 12.8; 95% CI = 12.23-12.94), with only 22.2% nonadherent in the first year (8.2% overall) becoming adherent in the second year of therapy. Across both years, all minorities were less likely to be adherent (compared with whites), and average adherence differed among all geographic regions of the country. CONCLUSIONS: Within the first year of OAD therapy, medication adherence was suboptimal among veterans with DM, and second-year results indicate that adherence is likely to decline over time. Future studies should consider deeper regional and subgroup analysis to determine what contributes to variation in medication use in communities across the country.

PMID- 29578851 TI - Refill-Based Medication Use Quality Measures in Kidney Transplant Recipients: Examination of Proportion of Days Covered and Medication Possession Ratio. AB - BACKGROUND: The Pharmacy Quality Alliance's definition of proportion of days covered (PDC) and medication possession ratio (MPR) have not been examined as potential quality measures in the kidney transplant recipient population. OBJECTIVES: To (a) describe the frequency distribution of MPR and PDC using mycophenolic acid products in a real-world kidney transplant recipient population and (b) evaluate associations between MPR and PDC with late (> 90 days after transplantation) biopsy-proven acute rejection (BPAR). METHODS: This was a retrospective cohort study combining data from the Wisconsin Allograft Recipient Database with University of Wisconsin (UW) Health Specialty Pharmacy prescription claims and dispensing data from March 10, 2006, to June 30, 2012. Patients who met criteria for persistence filling mycophenolic acid prescriptions at UW Health Specialty Pharmacy in the first year following discharge from kidney transplantation surgery hospitalization were included. Patients were excluded if they were enrolled in a clinical trial, if they had BPAR within 90 days of transplantation, or if they did not have panel reactive antibody data available. PDC and MPR were calculated over 360 days after discharge, and multivariable analyses were performed to determine if there were associations between PDC or MPR with late BPAR within 3 years. RESULTS: This study included 388 patients. The incidence of 3-year late BPAR was 5.1% (n = 20). Characteristics of patients who experienced late BPAR were largely consistent with those who did not experience late BPAR, with the exception of number of hospital readmissions, which was higher among patients who experienced late BPAR. The frequency distribution of PDC and MPR exhibited a skewed left distribution, with a median PDC of 0.972 and a median MPR of 1.000. Higher PDC was associated with lower odds of late BPAR (OR = 0.041, 95% CI = 0.004-0.417) in multivariable analysis, as was a higher MPR (OR = 0.041, 95% CI = 0.004-0.419). CONCLUSIONS: MPR and PDC may be calculated from data available to pharmacies and health plans, and each was associated with 3 year late BPAR among patients who did not experience early BPAR. However, the construct validity of these medication adherence measures requires further study. DISCLOSURES: This study was not funded.

PMID- 29578852 TI - Economic Burden of Patients with Inadequate Response to Targeted Immunomodulators for Rheumatoid Arthritis. AB - BACKGROUND: Targeted immunomodulators (TIMs), including biologic disease modifying antirheumatic drugs (DMARDs) and JAK/STAT inhibitors, are effective therapies for rheumatoid arthritis (RA), but some patients fail to respond or lose response over time. This study estimated the real-world prevalence of RA patients with inadequate responses to an initial TIM (nonresponders) in the United States and assessed their direct and indirect economic burden compared with treatment responders. METHODS: Administrative claims data (January 1999 March 2014) from a large private-insurer database were used, which included work loss data from a subset of reporting companies. Eligible patients (classified as responders and nonresponders) had >= 1 claim for a TIM approved for the treatment of RA and >= 2 RA diagnoses in the claims history, with continuous pharmaceutical and medical benefit eligibility for 6 months before (baseline) and 12 months after (study period) the date of the first TIM claim (index date). All-cause and RA-related health care resource use (HCRU) and costs, work loss, and indirect costs during the study period were compared for responders versus nonresponders. Multivariable regression was used to adjust for baseline covariates. Sensitivity analyses of HCRU and direct costs were conducted for patients with index dates before and after 2008 to account for different approval dates of TIMs. RESULTS: Of 7,540 eligible patients with RA, 2,527 (34%) were classified as responders, and 5,013 (66%) were classified as nonresponders; 407 and 723 had work-loss data, respectively. After adjusting for baseline covariates, nonresponders had significantly higher HCRU, including inpatient admissions (incidence rate ratio [IRR] = 1.94), outpatient visits (IRR = 1.19), emergency department visits (IRR = 1.53), and number of prescription fills (IRR = 1.09; all, P < 0.001). Nonresponders also had significantly higher adjusted all-cause ($12,868 vs. $9,621, respectively) and RA-related ($5,740 vs. $4,495; both, P < 0.001) medical costs compared with responders. In addition, nonresponders reported significantly more days of work lost compared with responders (22.1 vs. 16.7 days, respectively; IRR = 1.21; P = 0.007) and higher indirect costs ($3,548 vs. $2,890; P = 0.002). Sensitivity analyses of HCRU and direct costs by index date (before and after 2008) were consistent with the full sample. CONCLUSIONS: A large portion of patients with RA had inadequate responses to their initial TIM therapy with significantly higher economic burden, including higher HCRU, medical costs, and indirect costs due to work loss, compared with TIM therapy responders.

PMID- 29578853 TI - Michigan Pharmacists Transforming Care and Quality: Developing a Statewide Collaborative of Physician Organizations and Pharmacists to Improve Quality of Care and Reduce Costs. AB - BACKGROUND: Inappropriate drug use, increasing complexity of drug regimens, continued pressure to control costs, and focus on shared accountability for clinical measures drive the need to leverage the medication expertise of pharmacists in direct patient care. A statewide strategy based on the collaboration of pharmacists and physicians regarding patient care was developed to improve disease state management and medication-related outcomes. PROGRAM DESCRIPTION: Blue Cross Blue Shield of Michigan (BCBSM) partnered with Michigan Medicine to develop and implement a statewide provider-payer program called Michigan Pharmacists Transforming Care and Quality (MPTCQ), which integrates pharmacists within physician practices throughout the state of Michigan. As the MPTCQ Coordinating Center, Michigan Medicine established an infrastructure integrating clinical pharmacists into direct patient care within patient-centered medical home (PCMH) practices and provides direction and guidance for quality and process improvement across physician organizations (POs) and their affiliated physician practices. The primary goal of MPTCQ is to improve patient care and outcomes related to Medicare star ratings and HEDIS measures through integration of clinical pharmacists into direct patient care. The short-term goal is to adopt and modify Michigan Medicine's integrated pharmacist practice model at participating POs, with the long-term goal of developing a sustainable model of pharmacist integration at each PO to improve patient care and outcomes. Initially, pharmacists are delivering disease management (diabetes, hypertension, and hyperlipidemia) and comprehensive medication review services with future plans to expand clinical services. OBSERVATIONS: In 2015, 10 POs participated in year 1 of the program. In collaboration with the MPTCQ Coordinating Center, each PO identified 1 "pharmacist transformation champion" (PTC). The PTC implemented the integrated pharmacist model at 2 or 3 practice sites with at least 2 practicing physicians per site. IMPLICATIONS: MPTCQ is a unique collaboration between a large academic institution, physician organizations, a payer, and a statewide coordinating center to improve patient care and address medication related challenges by integrating pharmacists into a PCMH network. Pharmacists can actively provide their medication expertise to physicians and patients and optimize quality measure performance.

PMID- 29578854 TI - Increasing Access to Hepatitis C Virus Medications: A Program Model Using Patient Navigators and Specialty Pharmacy to Obtain Prior Authorization Approval. AB - BACKGROUND: Obtaining prior authorization (PA) approval for the new direct-acting antiviral (DAA) hepatitis C medications is time consuming and requires specific expertise. Our primary care-based program treats hepatitis C virus (HCV)-infected patients at an urban academic medical center and employs patient navigators trained in the PA process who collaborate with a nurse and specialty pharmacy to manage the PA process. OBJECTIVE: To demonstrate the rate of PA approvals for our programmatic model and determine potential predictors of PA approval. METHODS: We conducted a review of program databases and medical records of patients for whom DAA hepatitis C medications were ordered between November 1, 2014, and October 31, 2015 (n = 197). We first evaluated patient characteristics associated with the number of steps to approval. Then we used a multivariable ordinal regression to determine independent predictors of fewer steps to approval. Using Kaplan Meier methods, we assessed patient characteristics associated with approval time and then fit a multivariable Cox regression model to determine independent predictors of time to approval. RESULTS: Of the 197 patients, 69% (n = 136) had Medicaid; 12% (n = 24) had Medicare; 10% (n = 19) had both Medicaid and Medicare; 5% (n = 10) had private insurance; and 4% (n = 8) were uninsured. Ninety-three percent of the patients were eventually approved for HCV treatment. The steps in the PA cascade were approval on first submission (37%; mean days = 30.7; SD = 29.9); approval after internal appeal (45%; mean days = 66.8; SD = 70.5); approval after external appeal (11%; mean days = 124.7; SD = 60.2); and no approval obtained (7%). Unadjusted factors found to have a P value < 0.200 in relation to fewer steps in the PA cascade were older age, female gender, non Medicaid insurance, comorbid hypertension, comorbid diabetes, being domiciled, and being nongenotype 2. After adjustment, non-Medicaid insurance and nongenotype 2 remained significant. In survival analysis, non-Medicaid insurance and mid range fibrosis were associated with fewer days to PA approval. CONCLUSIONS: Our program obtained 93% of PA approvals for hepatitis C medications. Patient navigators collaborating with a nurse and specialty pharmacy as a program may improve the PA approval process, although further research with a control group is necessary.

PMID- 29578855 TI - A Comparison of Pharmacy Dispensing Channel Use and Adherence to Specialty Drugs Among Medicare Part D Beneficiaries. AB - BACKGROUND: Nonadherence to specialty drugs has been associated with poor clinical and economic outcomes. Studies conducted using commercial health plans suggest that patients who use specialty pharmacies have higher adherence compared with patients using retail pharmacies. However, little is known about the frequency of dispensing channel use or the association of dispensing channel use with adherence to specialty drugs among Medicare Part D beneficiaries. OBJECTIVES: To (a) describe the use of pharmacy dispensing channels by patients using self-administered specialty drugs in Medicare Part D and (b) study the association between dispensing channel use and adherence to specialty drugs in this population. METHODS: This study analyzed 2010 Medicare Part D data. Specialty drugs were defined as drugs with a mean cost >= $600 per month. We identified the top 13 specialty medications by cost and classified patients into the following classes: anticancer, disease-modifying therapy (DMT), and tumor necrosis factor inhibitor (TNFi). Dispensing channels included retail, specialty, mail order, long-term care, and other. We included patients continuously enrolled in Medicare Part D who had >= 1 prescription for a specialty medication before the end of June 2010. These patients were followed until the end of 2010. Patients with proportion of days covered (PDC) >= 0.8 were considered adherent. Adherence rates were calculated by weighting for therapeutic class after weighting for drug mix. Multivariable logistic regression analysis examined the association between dispensing channel and adherence. RESULTS: Of 5,430 patients, 1,248 were dispensed anticancer medications, 1,723 were dispensed DMTs, and 2,459 were dispensed TNFi drugs. About 16% used specialty, 74% used retail, 4% used mail order, 4% used long-term care, and 3% used other channels. The distribution pattern was similar when stratified by therapeutic class. In the descriptive analysis, patients using the specialty channel for the anticancer and TNFi classes had 7% and 10% higher adherence rates, respectively, compared with retail. For the DMT class, the adherence rate was higher for mail order but similar for retail and specialty channels. Adjusted analysis found that overall, specialty users had 23% higher odds for being adherent compared with retail users (P = 0.0104). For the anticancer and TNFi classes, specialty users had 39% (P = 0.0311) and 55% (P = 0.0005) higher odds, respectively, for being adherent than retail users. For the DMT class, no significant association was observed between dispensing channel and adherence (P = 0.9691). CONCLUSIONS: Nearly three quarters of Medicare patients on specialty therapies included in this study used the retail channel compared with one sixth who used the specialty channel. Overall, specialty channel use was associated with higher adherence compared with retail channel use. However, this relationship varied by therapeutic class. The specialty channel was associated with higher adherence among patients from the anticancer and TNFi classes but not among the DMT class. DISCLOSURES: No funding supported this study.

PMID- 29578856 TI - Drug treatment of hypertension in older patients with diabetes mellitus. AB - INTRODUCTION: Hypertension is more prevalent in the elderly (age>65 years) diabetic population than in the general population and shows an increasing prevalence with advancing age. Both diabetes mellitus (DM) and hypertension are independent risk factors for cardiovascular (CV) related morbidity and mortality. Optimal BP targets were not identified in elderly patients with DM and hypertension. Areas covered: In this review article, the authors briefly discuss the pathophysiology of hypertension in elderly diabetics, present evidence with various antihypertensive drug classes supporting the treatment of hypertension to reduce CV events in older diabetics, and then discuss the optimal target BP goals in these patients. Expert opinion: Clinicians should have a BP goal of less than 130/80 mm in all elderly patients with hypertension and DM, especially in those with high CV-risk. When medications are required for optimal BP control in addition to lifestyle measures, either thiazide diuretics, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, or calcium channel blockers should be considered as initial therapy. Combinations of medications are usually required in these patients because BP control is more difficult to achieve in diabetics than those without DM. PMID- 29578857 TI - Interest in prescribing buprenorphine among resident and attending physicians at an urban teaching clinic. AB - BACKGROUND: Opioid use disorders are a major medical and public health concern. Buprenorphine is approved for the treatment of opioid use disorders; however, a shortage of physicians prescribing buprenorphine is a significant barrier to treatment access. The aims of this study were to evaluate opinions of internal medicine attending and resident physicians about buprenorphine and assess interest in becoming waivered to prescribe. METHODS: Internal medicine resident and attending physicians at a primary care clinic in a large academic hospital were invited to complete surveys. The study sample was composed of physicians who were not waivered to prescribe buprenorphine. Survey data included demographic information, level of training, buprenorphine waiver status, interest in becoming waivered to prescribe buprenorphine, and beliefs about buprenorphine for treatment of opioid use disorders. High interest in becoming waivered was defined as a Likert response >3 (1 = No interest, 5 = Very interested). RESULTS: Of the 44 physician respondents, 39 were not waivered to prescribe buprenorphine and constituted the sample; of those, 27 were residents and 12 were attending physicians. Twenty-six of the 39 nonwaivered respondents (66.7%) had high interest in becoming waivered. Those with high interest in becoming waivered were significantly more likely to be younger (P = .007) and to strongly believe in buprenorphine effectiveness (P = .023). DISCUSSION: Most physicians in this academic training program showed high interest in prescribing buprenorphine, and belief in buprenorphine effectiveness was associated with high interest in becoming waivered. PMID- 29578859 TI - Inhibition of BMP4 and Alpha Smooth Muscle Actin Expression in LX-2 Hepatic Stellate Cells by BMP4-siRNA Lipid Based Nanoparticle. AB - PURPOSE: To develop and characterize vitamin A (VA)-coupled liposomes for the targeted delivery of BMP4-siRNA to hepatic stellate cells (HSC). VA was selected to increase the uptake by HSC based on their function in the storage of VA. METHODS: DOTAP/DOPE liposomes were prepared by film hydration method and their surfaces were decorated with VA. The cytotoxicity of VA-conjugated liposomes was evaluated by the WST-1 assay. Inhibition of BMP4 and alpha-SMA was determined by PCR and ELISA. RESULTS: VA-coated lipoplexes exhibited an average particle sizes less than 200 nm and zeta potential around +25 mV both determined using ZetaPALS. Inclusion of VA to liposomal surfaces significantly enhanced their cellular uptake without affecting cytotoxicity. VA-coupled liposomes carrying BMP4-siRNA resulted in a significant reduction in BMP4 and alpha-SMA at both mRNA and protein levels. Conclusion: VA-coated liposomes were successfully designed to deliver BMP4-siRNA to specifically target HSC. The novel delivery system discussed herein may serve as a potential therapeutic strategy for the treatment of liver fibrosis in the future. This article is open to POST-PUBLICATION REVIEW.

PMID- 29578858 TI - Water-Based Aerobic Training Successfully Improves Lipid Profile of Dyslipidemic Women: A Randomized Controlled Trial. AB - PURPOSE: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. METHOD: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval aerobic training twice a week at intensities ranging from 9 to 15 on the Borg Scale of Perceived Exertion. Total cholesterol (TC), triglycerides (TG), high- (HDL) and low- (LDL) density lipoprotein, TC/HDL ratio, LPL levels, and peak oxygen consumption (VO2peak) were evaluated before and after 12 weeks in both groups. RESULTS: The WA group elicited decreases in TC (9%; effect size [ES] = 0.69; 95% CI [0.05, 1.33]), LDL (16%; ES = 0.78; 95% CI [0.13, 1.42]), and the TC/HDL ratio (17%; ES = 1.13; 95% CI [0.46, 1.79]), as well as increases in VO2peak (10%; ES = 0.64; 95% CI [0.002, 1.27]) and HDL (10%; ES = 0.28; 95% CI [-0.35. 0.90]), without significant changes in TG (ES = 0.16; 95% CI [-0.46, 1.79]) and LPL (ES = 0.36; 95% CI [ 0.27, 0.98]) levels. In the CG, no statistically significant changes in any of these variables were found (TC, ES = 0.19, 95% CI [-0.43, 0.82]; LDL, ES = 0.22, 95% CI [-0.40, 0.85]; HDL, ES = 0.05, 95% CI [-0.57, 0.67]; TG, ES = 0.09, 95% CI [-0.53, 0.71]; TC/HDL ratio, ES = 0.20, 95% CI [-0.42, 0.82]; LPL, ES = 0.02, 95% CI [-0.60, 0.64]; VO2peak, ES = 0.20, 95% CI [-0.42, 0.82]). CONCLUSION: Water based interval aerobic training positively affected the lipid profile in premenopausal dyslipidemic women. PMID- 29578860 TI - Positive Bacteriological Analyses in Individuals With Diabetes Mellitus: Preliminary Results From a Forensic Study. AB - Increased infection susceptibility in the diabetic population is a controversial issue in the clinical field. The greater frequency of infections in diabetic patients has been speculated as caused by the hyperglycemic environment that favors immune dysfunction. The aim of this study was to investigate the proportion of positive bacterial cultures in a series of diabetic individuals who underwent forensic investigations and assess the frequency of hyperglycemia at the time of death in these cases as well as the percentage of diabetics with cause of death due to bacterial infection. Forensic autopsy cases characterized by positive bacterial cultures and pre-existing diagnosis of diabetes mellitus were included in the study. Initial findings revealed that 12% (7/58 cases) of positive bacterial cultures concerned individuals with a pre-existing diagnosis of diabetes mellitus. Bacterial infection was considered to be the cause of death in 22% (7/31 cases) of diabetics with positive bacterial cultures. Hyperglycemia could be identified in 1 case only at the time of death. These preliminary results highlight the usefulness of systematically performing postmortem bacteriology in the forensic setting to more precisely characterize infectious risk factors in diabetics.

PMID- 29578861 TI - Alzheimer Disease Biomarkers and Driving in Clinically Normal Older Adults: Role of Spatial Navigation Abilities. AB - PURPOSE: Older adults experience impaired driving performance, and modify their driving habits, including limiting amount and spatial extent of travel. Alzheimer disease (AD)-related pathology, as well as spatial navigation difficulties, may influence driving performance and driving behaviors in clinically normal older adults. We examined whether AD biomarkers [cerebrospinal fluid (CSF) concentrations of Abeta42, tau, and ptau181] were associated with lower self reported spatial navigation abilities, and whether navigation abilities mediated the relationship of AD biomarkers with driving performance and extent. METHODS: Clinically normal older adults (n=112; aged 65+) completed an on-road driving test, the Santa Barbara Sense of Direction scale (self-report measure of spatial navigation ability), and the Driving Habits Questionnaire for an estimate of driving extent (composite of driving exposure and driving space). All participants had a lumbar puncture to obtain CSF. RESULTS: CSF Abeta42, but not tau or ptau181, was associated with self-reported navigation ability. Lower self reported navigation was associated with reduced driving extent, but not driving errors. Self-reported navigation mediated the relationship between CSF Abeta42 and driving extent. CONCLUSIONS: Findings suggest that cerebral amyloid deposition is associated with lower perceived ability to navigate the environment, which may lead older adults with AD pathology to limit their driving extent.

PMID- 29578864 TI - Spinal Protein Kinase Mzeta Regulates alpha-Amino-3-hydroxy-5-methyl-4 isoxazolepropionic Acid Receptor Trafficking and Dendritic Spine Plasticity via Kalirin-7 in the Pathogenesis of Remifentanil-induced Postincisional Hyperalgesia in Rats. AB - BACKGROUND: Intraoperative remifentanil anesthesia exaggerates postoperative pain sensitivity. Recent studies recapitulate the significance of protein kinase Mzeta in alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor mediated pathologic pain. Kalirin-7, a Rho guanine nucleotide exchange factor, coordinates AMPA receptor trafficking and dendritic spine plasticity. This study examines whether protein kinase Mzeta and Kalirin-7 contribute to remifentanil induced postincisional hyperalgesia via AMPA receptor. METHODS: Plantar incision was performed 10 min after the start of remifentanil infusion (1 ug . kg . min for 60 min). Paw withdrawal threshold (primary outcome), spinal protein kinase Mzeta activity, Kalirin-7 expression, AMPA receptor trafficking, and spine morphology were assessed. Protein kinase Mzeta inhibitor and Kalirin-7 knockdown by short hairpin RNA elucidated the mechanism and prevention of hyperalgesia. Whole-cell patch-clamp recording analyzed the role of protein kinase Mzeta in spinal AMPA receptor-induced current. RESULTS: Remifentanil reduced postincisional paw withdrawal threshold (mean +/- SD, control vs. hyperalgesia, 18.9 +/- 1.6 vs. 5.3 +/- 1.2 g, n = 7) at postoperative 48 h, which was accompanied by an increase in spinal protein kinase Mzeta phosphorylation (97.8 +/- 25.1 vs. 181.5 +/- 18.3%, n = 4), Kalirin-7 production (101.9 +/- 29.1 vs. 371.2 +/- 59.1%, n = 4), and number of spines/10 um (2.0 +/- 0.3 vs. 13.0 +/- 1.6, n = 4). Protein kinase Mzeta inhibitor reduced remifentanil-induced hyperalgesia, Kalirin-7 expression, and GluA1 trafficking. Incubation with protein kinase Mzeta inhibitor reversed remifentanil-enhanced AMPA receptor induced current in dorsal horn neurons. Kalirin-7 deficiency impaired remifentanil-caused hyperalgesia, postsynaptic GluA1 insertion, and spine plasticity. Selective GluA2-lacking AMPA receptor antagonist prevented hyperalgesia in a dose-dependent manner. CONCLUSIONS: Spinal protein kinase Mzeta regulation of GluA1-containing AMPA receptor trafficking and spine morphology via Kalirin-7 overexpression is a fundamental pathogenesis of remifentanil-induced hyperalgesia in rats.

AB - PURPOSE: To investigate the knowledge, attitudes, and practice patterns of primary care physicians regarding administration of the herpes zoster (HZ) vaccine at NYU Langone Health (NYULH). METHODS: A cross-sectional online survey was distributed from January to March 2017 to all physicians in the Division of General Internal Medicine and Clinical Innovation at NYULH across 5 different practice settings. RESULTS: The response rate was 26% (138 of 530). Of the surveyed physicians, 76% (100/132) agreed that the HZ vaccine was an important clinical priority, compared with 93% and 94% for influenza and pneumococcal vaccination, respectively (P < 0.001). Only 35% (47/132) strongly agreed that it was important, compared with 68% (90/132) and 74% (98/132) who strongly agreed that pneumococcal and influenza vaccines, respectively, were important. Respondents estimated that 43% of their immunocompetent patients aged 60 or older received the HZ vaccine, whereas only 11% of patients aged 50 to 59 received the HZ vaccine (P < 0.001). The rate of HZ vaccination was lower in public hospitals (26%) than in the NYULH faculty group practice (46%) (P = 0.007). A greater percent (67% and 72%) of their patients have received influenza and pneumococcal vaccines, respectively (P < 0.001). Almost all doctors (99%, 131/132) consider the Centers for Disease Control and Prevention recommendations important in determining vaccination practices. CONCLUSIONS: HZ vaccination rates remain relatively low compared with rates of influenza and pneumonia vaccination. The recommendation for vaccination against zoster by the Centers for Disease Control and Prevention for individuals aged 50 years and older and stronger recommendations by primary care physicians for administration of zoster vaccines are needed to increase HZ vaccination rates. PMID- 29578866 TI - Endoscopic ultrasound-guided gallbladder drainage for acute cholecystitis with a lumen-apposing metal stent: a systematic review of case series. AB - Management of patients with acute cholecystitis unfit for surgery is challenging. Recently, endoscopic ultrasound (EUS)-guided gallbladder drainage with a lumen apposing metal stent (LAMS) has been introduced for these patients. We performed a systematic review and pooled-data analysis in this field. A comprehensive review of case series on gallbladder drainage with EUS-guided LAMS placement was performed. Only case series with at least five patients were considered. The rates of technical success, clinical success, and adverse events were computed. Overall, nine case series with a total of 226 patients were identified. The stent was positioned successfully in 215 cases [95.1%, 95% confidence interval (CI)=92.3-98]. Clinical success was achieved in 207 patients, corresponding to a 91.6% (95% CI=88-95.2) rate at intention-to-treat analysis and 96.3% (95% CI=93.7 99) at per-protocol analysis. A total of 24 (10.6%) adverse events occurred, including 11 (4.9%) cases during the procedure, and 13 (5.7%) observed at follow up (median=6 months; range: 2-12 months). A surgical approach was required in only 25% of patients with a major adverse event. No case of procedure-related death was reported. EUS-guided LAMS placement for gallbladder drainage in patients with acute cholecystitis not suitable for surgery is highly successful and acceptably safe. PMID- 29578867 TI - The relationship between urinary genistein levels and serum alanine aminotransferase levels in adults in the USA: National Health and Nutrition Examination Survey 1999-2010. AB - BACKGROUND: Genistein, a phytoestrogen with similarities to female sex hormones, has been shown to protect against oxidative stress and fibrosis in nonalcoholic fatty liver injury in animal studies. However, few studies have examined genistein's effects on liver function in humans. PARTICIPANTS AND METHODS: We analyzed data from the National Health and Nutrition Examination Survey from 1999 to 2010. Individuals younger than 21 years, with viral hepatitis, or with serum alanine aminotransferase (ALT) at the extremes of distribution (5% on each extreme) were excluded. Urinary genistein was normalized by urinary creatinine levels. The relationship between normalized urinary genistein (nUG) and serum ALT was examined using linear regression models with and without adjustment for potential confounders, and the differential effect of sex was examined using an interaction term. RESULTS: Of the 9864 participants, 52% were female, 50% were White, 24% were elderly, 36% had hypertension, 12% had diabetes, and 8.1% were heavy alcohol drinkers. Serum ALT was significantly lower in the highest quartile compared with the lowest quartile of nUG (22.3 vs. 23.5 U/l; P<0.001). In adjusted models, individuals in the highest quartile had 0.75 U/l lower ALT levels than those in the lowest quartile (P=0.02). We found a significant difference in ALT levels between the lowest and highest quartiles of nUG in males, but not in females (difference in differences=1.77 U/l, interaction P=0.04). CONCLUSION: We found a statistically significant association between higher nUG and lower serum ALT in males, but not in females. The sex-specific role of genistein in mitigating liver disease merits further study. PMID- 29578868 TI - Hip Joint Effusion-Synovitis Is Associated With Hip Pain and Sports/Recreation Function in Female Professional Ballet Dancers. AB - OBJECTIVE: To compare hip joint effusion-synovitis prevalence in professional ballet dancers with nondancing athletes and to evaluate the relationship between effusion-synovitis and clinical measures and cartilage defects. DESIGN: Case control study. SETTING: Elite ballet and sport. PARTICIPANTS: Forty-nine professional ballet dancers and 49 age-matched and sex-matched athletes. INDEPENDENT VARIABLES: Group (dancers/athletes), sex, age, years of training, Copenhagen Hip and Groin Outcome Scores (HAGOSs), hip rotation range of motion (ROM), generalized joint hypermobility (GJH), and hip cartilage defect scores. MAIN OUTCOME MEASURES: Hip joint effusion-synovitis (absent, grade 1 = 2-4 mm, grade 2 = >4 mm) scored with 3-Tesla magnetic resonance imaging. RESULTS: Hip joint effusion-synovitis was found in 22 (45%) dancers and 13 (26.5%) athletes (P = 0.06). Grade 2 effusion-synovitis was only found in dancers (n = 8, r = 0.31, P = 0.009). The prevalence of effusion-synovitis was similar in men (n = 11, 26%) and women (n = 24, 43%, P = 0.09). Female dancers with effusion-synovitis had lower HAGOS pain (r = 0.63, P = 0.001) and sports/recreation scores (r = 0.66, P = 0.001) compared with those without effusion-synovitis. The HAGOS scores were not related to effusion-synovitis in male dancers or female and male athletes (P > 0.01 for all). Effusion-synovitis was not related to hip ROM, GJH, or cartilage defect scores (P > 0.05 for all). CONCLUSIONS: Hip joint effusion-synovitis was related to higher levels of pain and lower sports/recreation function in female ballet dancers. Effusion-synovitis was not related to hip rotation ROM, GJH or cartilage defects. Larger sized joint effusion-synovitis was exclusively found in dancers. PMID- 29578869 TI - Orthopedic Injuries in Professional Surfers: A Retrospective Study at a Single Orthopedic Center. AB - BACKGROUND: Literature regarding surfing injuries is scarce and most studies report a high number of minor injuries. Recent literature suggests that musculoskeletal injuries are more common than previously reported. In the mid 2000s, competitive surfing has seen an increase in aerial maneuvers, as they have become more highly rewarded by the judging panel, which may be contributing to a change in injury patterns. Our goal was to evaluate orthopedic injuries in professional surfers. HYPOTHESIS: Orthopedic injuries in professional surfers are diverse and have evolved with skill and technology. STUDY DESIGN: Retrospective observational study. LEVEL OF EVIDENCE: Level 4 Case Series. METHODS: Medical records of professional surfers from a single orthopedic center between 1991 and 2016 were reviewed. Injuries sustained while surfing and chronic injuries related to surfing were included. Site of injury, diagnosis, and treatment were recorded along with demographic data. RESULTS: In total, 163 injuries in 86 athletes were recorded. The median injury age was 28.5 years (range 12-62 years) and 92.6% of patients were male. The most frequently injured body parts were the knee (28.2%), ankle (22.1%), and shoulder (19%). Most knee injuries were of the medial collateral ligament at 49%, with 75% of ankle injuries being sprains, and in shoulder, 48% had instability, 42% had a rotator cuff tear, and 35% had a superior anterior-posterior labral tear. Lower extremity injuries primarily affected the surfers' back leg (72.5%). In all, 34.6% of all injuries required surgical intervention and involved shoulder injuries most the time. CONCLUSIONS: The most common orthopedic injuries in professional surfers involve the knee, ankle, shoulder, hip, and back. Surfers' rear extremities were preferentially injured which is the extremity responsible for power and torque. Shoulder injuries increased the probability of an operative intervention. Last, overuse injuries (femoral-acetabular impingement, rotator cuffs) occurred in the older surf population compared with more acute injuries (ankle sprains/fractures, anterior cruciate ligament tears) which is also consistent with time to surgery.

AB - We present here a case of metastatic adrenocortical carcinoma with bilateral lung nodules. The patient had been treated with mitotane therapy initially and then was later referred for chemotherapy. There was progression of disease noted on the F-FDG PET/CT. Ga prostate-specific membrane antigen (PSMA) PET/CT was planned to explore the possibility of future treatment with Lu-DKFZ-PSMA-617. It revealed peripheral increased uptake of Ga-HBED-CC-PSMA equal to liver uptake. PMID- 29578872 TI - 68Ga-Prostate-Specific Membrane Antigen PET/CT in Triple-Negative Breast Cancer. AB - The prostate-specific membrane antigen (PSMA) is a transmembrane protein with elevated expression in prostate cancer cells. Breast cancer also shows PSMA expression. We present the case of a 30-year-old woman with triple-negative bilateral breast carcinoma who underwent bilateral mastectomy, chemotherapy, and radiotherapy. She developed a left chest wall and liver recurrence after primary therapy. Her recurrent disease was also triple-negative. In view of the known poor prognosis and very limited therapeutic options, we performed Ga-PSMA PET/CT scan to explore the possibility of PSMA-based therapy as a future option after exhausting standard-of-care treatments.

AB - A 57-year-old man with renal mass underwent Tc-diethylenetriaminepentaacetic acid renal dynamic scintigraphy for evaluation of renal function. The blood flow phase images demonstrated a focus of abnormal increased tracer uptake in the region of the right lower quadrant. On the functional phase images, the activity became unimpressive gradually. This focus corresponded to an osteolytic lesion in the right ilium on the CT and MR images, which was a typical pattern of bone metastasis. PMID- 29578874 TI - Extradural Arachnoid Cyst Excision. AB - Arachnoid cysts are an uncommon postoperative complication and can result in back pain, radiculopathy, and/or cauda equina syndrome. For symptomatic postoperative arachnoid cysts, surgical management is the accepted treatment. While excision of arachnoid cysts is the preferred surgical method, cysts with adhesions to nerve roots and/or dura can be treated with cyst fenestration to reduce morbidity of excision. Surgeons should be prepared for dural defects after cyst excision, which can require dural grafting and lumbar drains for cerebrospinal fluid diversion. PMID- 29578875 TI - Strategies for the Prevention and Treatment of Surgical Site Infection in the Lumbar Spine. AB - Surgical site infection (SSI) following spine surgery can be devastating for both the patient and the surgeon. It leads to significant morbidity and associated health care costs, from readmissions, reoperations, and subsequent poor clinical outcomes. Complications associated with SSI following spine surgery include pseudarthrosis, neurological deterioration, sepsis, and death. Its management can be very challenging. The diagnosis of SSI involves the interpretation of combined clinical, laboratory, and occasionally radiologic findings. Most infections can be treated with an appropriate course of antibiotics and bracing if required. Surgical intervention is usually reserved for infections resistant to medical management, the need for open biopsy/culture, evolving spinal instability or deformity, and neurologic deficit or deterioration. A thorough knowledge of associated risk factors is required and patients should be stratified for risk preoperatively. The multifaceted approach of risk stratification, early diagnosis and effective treatment, is essential for successful prevention and effective treatment and crucial for a satisfactory outcome. PMID- 29578876 TI - Surgical Strategies to Prevent Adjacent Segment Disease in the Cervical Spine. AB - The most popular approach to treating symptomatic cervical disk disease is anterior cervical discectomy and fusion. Although this procedure has significant long-term clinical success, it is associated with progressive adjacent segment degeneration with an annual incidence of ~3%. Total disk arthroplasty was designed as an alternative to fusion that could preserve segmental motion at the operative level and potentially delay or prevent adjacent-level breakdown. The etiology of adjacent segment pathology (ASP) is multifactorial, and it is likely that most cases of ASP are unavoidable. When attempting to surgically prevent ASP, it is important to consider nonfusion alternatives, be judicious in one's level selection, and attempt to restore sagittal alignment. When ASP becomes a clinical problem, it is important to have an algorithm for how best to treat it. PMID- 29578877 TI - Thoracolumbar Burst Fractures. AB - Thoracolumbar burst fractures are high-energy vertebral injuries, which commonly can be treated nonoperatively. Consideration of the injury pattern, extent of comminution, neurological status, and integrity of the posterior ligamentous complex may help determine whether operative management is appropriate. Several classification systems are contingent upon these factors to assist with clinical decision-making. A multitude of operative procedures have been shown to have good radiographic and clinical outcomes with extended follow-up, and treatment choice should be based on the individual's clinical and radiographic presentation. PMID- 29578878 TI - Intra-Abdominal Hypertension Is More Common Than Previously Thought: A Prospective Study in a Mixed Medical-Surgical ICU. AB - OBJECTIVES: To determine the prevalence of intra-abdominal hypertension in mixed medical-surgical critically ill patients using modern definitions and measurement techniques. Secondarily to determine variables associated with intra-abdominal hypertension and ICU mortality. DESIGN: A prospective observational study. SETTING: Single institution trauma, medical and surgical ICU in Canada. PATIENTS: Consecutive adult patients admitted to the ICU (n = 285). INTERVENTION: Intra abdominal pressure measurements twice a day during admission to the ICU. MEASUREMENTS AND MAIN RESULTS: In 285 patients who met inclusion criteria, 30% were diagnosed with intra-abdominal hypertension at admission and a further 15% developed intra-abdominal hypertension during admission. The prevalence of abdominal compartment syndrome was 3%. Obesity, sepsis, mechanical ventilation, and 24-hour fluid balance (> 3 L) were all independent predictors for intra abdominal hypertension. Intra-abdominal hypertension occurred in 28% of nonventilated patients. Admission type (medical vs surgical vs trauma) was not a significant predictor of intra-abdominal hypertension. Overall ICU mortality was 20% and was significantly higher for patients with intra-abdominal hypertension (30%) compared with patients without intra-abdominal hypertension (11%). Intra abdominal hypertension of any grade was an independent predictor of mortality (odds ratio, 3.33; 95% CI, 1.46-7.57). CONCLUSIONS: Intra-abdominal hypertension is common in both surgical and nonsurgical patients in the intensive care setting and was found to be independently associated with mortality. Despite prior reports to the contrary, intra-abdominal hypertension develops in nonventilated patients and in patients who do not have intra-abdominal hypertension at admission. Intra-abdominal pressure monitoring is inexpensive, provides valuable clinical information, and there may be a role for its routine measurement in the ICU. Future work should evaluate the impact of early interventions for patients with intra-abdominal hypertension. PMID- 29578879 TI - What Faces Reveal: A Novel Method to Identify Patients at Risk of Deterioration Using Facial Expressions. AB - OBJECTIVES: To identify facial expressions occurring in patients at risk of deterioration in hospital wards. DESIGN: Prospective observational feasibility study. SETTING: General ward patients in a London Community Hospital, United Kingdom. PATIENTS: Thirty-four patients at risk of clinical deterioration. INTERVENTIONS: A 5-minute video (25 frames/s; 7,500 images) was recorded, encrypted, and subsequently analyzed for action units by a trained facial action coding system psychologist blinded to outcome. MEASUREMENTS AND MAIN RESULTS: Action units of the upper face, head position, eyes position, lips and jaw position, and lower face were analyzed in conjunction with clinical measures collected within the National Early Warning Score. The most frequently detected action units were action unit 43 (73%) for upper face, action unit 51 (11.7%) for head position, action unit 62 (5.8%) for eyes position, action unit 25 (44.1%) for lips and jaw, and action unit 15 (67.6%) for lower face. The presence of certain combined face displays was increased in patients requiring admission to intensive care, namely, action units 43 + 15 + 25 (face display 1, p < 0.013), action units 43 + 15 + 51/52 (face display 2, p < 0.003), and action units 43 + 15 + 51 + 25 (face display 3, p < 0.002). Having face display 1, face display 2, and face display 3 increased the risk of being admitted to intensive care eight fold, 18-fold, and as a sure event, respectively. A logistic regression model with face display 1, face display 2, face display 3, and National Early Warning Score as independent covariates described admission to intensive care with an average concordance statistic (C-index) of 0.71 (p = 0.009). CONCLUSIONS: Patterned facial expressions can be identified in deteriorating general ward patients. This tool may potentially augment risk prediction of current scoring systems. PMID- 29578880 TI - A strategy utilizing ambulatory monitoring and home and clinic blood pressure measurements to optimize the safety evaluation of noncardiovascular drugs with potential for hemodynamic effects: a report from the SYNERGY trial. AB - OBJECTIVE: The aim of this study was to perform a blood pressure (BP) safety evaluation in patients with an overactive bladder receiving solifenacin (an antimuscarinic agent), mirabegron (a beta3-adrenoceptor agonist), or both compared with placebo in the SYNERGY trial. PATIENTS AND METHODS: Patients were randomized to receive solifenacin 5 mg+mirabegron 50 mg (combination 5+50 mg); solifenacin 5 mg+mirabegron 25 mg (combination 5+25 mg); solifenacin 5 mg; mirabegron 50 mg; mirabegron 25 mg; or placebo for a double-blind 12-week treatment period. Systolic BP, diastolic BP, and heart rate were measured by ambulatory BP monitoring, and in the clinic or home. RESULTS: A total of 715 patients were analyzed in an ambulatory BP monitoring substudy. At the end of treatment, ambulatory BP monitoring measurements showed no consistent increases from baseline in the mean 24-h systolic BP or diastolic BP for combination versus monotherapy groups or for monotherapy groups versus placebo. Analysis of 1-h BP averages during the 6 h range that included the Tmax values of both study drugs showed no significant BP effects. Shift analysis (switch between different normotension/hypertension stages) did not show differences among the active and placebo groups, nor did outlier analysis of major BP changes differ between placebo and active treatment. Similarly, there were no significant signals in the 24-h heart rate. Office and home measurements were consistent with ambulatory BP monitoring findings. CONCLUSIONS: A paradigm of ambulatory BP monitoring analysis designed to test BP safety of noncardiovascular drugs showed that solifenacin plus mirabegron combination therapy during 12 weeks produced no meaningful changes in BP or heart rate. PMID- 29578881 TI - Aggressive Digital Papillary Adenocarcinoma: Population-Based Analysis of Incidence, Demographics, Treatment, and Outcomes. AB - BACKGROUND: As a rare cutaneous malignancy, epidemiologic and outcomes data for aggressive digital papillary adenocarcinoma (ADPA) are limited and no treatment guidelines exist. OBJECTIVE: To provide a population-based study of ADPA incidence and outcomes with a subgroup comparison of patients with localized versus regional disease. METHODS: Data from 18 registries within the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program were examined for patients with ADPA (1995-2013) to provide demographic- and cancer-related information, and to calculate race- and age-specific rate ratios, incidence, and mortality. Patients were stratified by the stage for further comparison. RESULTS: Ninety-four cases of ADPA were identified. Overall, ADPA incidence was 0.08 per 1,000,000 person-years, 4 times higher in males than in females (0.13 vs 0.03, p < .001), and most common in Caucasians. Regional disease spread occurred in 22.3% of patients and disease-specific mortality in 2.1% of patients. Patients with regional versus localized disease at diagnosis did not differ significantly in sex, age, race, primary site, tumor size, or mortality. CONCLUSION: Aggressive digital papillary adenocarcinoma is a rare malignancy with increasing incidence. Regional disease spread is not infrequent, but mortality is rare. Identification of patients best suited for additional diagnostic procedures or more extensive surgical resection remains challenging.

PMID- 29578883 TI - Skin and Soft Tissue Surgery in the Office Versus Operating Room Setting: An Analysis Based on Individual-Level Medicare Data. AB - BACKGROUND: The relative volume of skin and soft tissue excision and reconstructive procedures performed in the outpatient office versus facility (ambulatory surgical center or hospital) differs by specialty, and has major implications for quality of care, outcomes, development of guidelines, resident education, health care economics, and patient perception. OBJECTIVE: To assess the relative volume of surgical procedures performed in each setting (office vs ambulatory surgery center [ASC]/hospital) by dermatologists and nondermatologists. METHODS: A cross-sectional analytical study was performed using the Medicare public use file (PUF) for 2014, which includes every patient seen in an office, ASC, or hospital in the United States billed to Medicare part B. Data were divided by physician specialty and setting. RESULT: A total of 9,316,307 individual encounters were included in the Medicare PUF. Dermatologists account for 195,001 (2.1%) of the total. Dermatologists were more likely to perform surgical procedures in an office setting only (odds ratio 5.48 [95% confidence interval 5.05-5.95], p < .0001) than other specialists in aggregate. CONCLUSION: More than 90% of surgical procedures are performed in an office setting, and dermatologists are more than 5 times as likely as other specialists to operate in an office setting.

PMID- 29578885 TI - Analysis of Opioid Use Following Curative Cancer Treatment at a Large Urban Safety-net Hospital. AB - OBJECTIVES: This study examined the pattern of use and factors predicting prolonged prescription opioid medications among cancer patients following treatment with curative intent. MATERIALS AND METHODS: Patients diagnosed with cancer over a 3-year period at a large urban safety-net hospital were included. Univariate and multivariate analyses was used to identify factors associated with continued opioid use. RESULTS: Of the 199 patients included in the study, 38% continued to receive an opioid prescription well beyond the acute diagnosis and treatment phase. Mean age was 60.3 years, with a female preponderance (63%). Surgical resection only (31.6%) and the combination of surgery, chemotherapy, and radiation (19.7%) were the commonest treatment modalities. Pain-related comorbidities predating cancer diagnosis were reported in 53.3% of the patients, and about 33% were also on pain-modifying medications (odds ratio [OR], 3.58; 95% confidence interval [CI], 1.92-6.77; Fisher exact test P<0.001). Average number of prescriptions received per patient was 4.8 (range, 1 to 31), over an average of 9.5 months (range, 1.2 to 28.1 mo). Mean morphine milligram equivalents prescribed per prescription was 319 mg (range, 48 to 2475 mg). According to multivariate model, patients who received chemotherapy (OR, 7.25; 95% CI, 2.09 25.17; P=0.0018), or pain-modifying medications (OR, 4.61; 95% CI, 2.25-9.44; P<0.0001) were significantly more likely to continue to receive prescriptions for opioids. DISCUSSION: Treatment with chemotherapy, pain-modifying medications, cancer stage, and interval between diagnosis and treatment are the best predictors for continuous opioid use. The current epidemic of opioid misuse and abuse makes examination current practices and identifification of areas of improvement imperative. PMID- 29578886 TI - Development of a Novel Bone Conduction Verification Tool Using a Surface Microphone: Validation With Percutaneous Bone Conduction Users. AB - OBJECTIVES: To determine if a newly-designed, forehead-mounted surface microphone would yield equivalent estimates of audibility when compared to audibility measured with a skull simulator for adult bone conduction users. DESIGN: Data was analyzed using a within subjects, repeated measures design. There were two different sensors (skull simulator and surface microphone) measuring the same hearing aid programmed to the same settings for all subjects. We were looking for equivalent results. PATIENTS: Twenty-one adult percutaneous bone conduction users (12 females and 9 males) were recruited for this study. Mean age was 54.32 years with a standard deviation of 14.51 years. Nineteen of the subjects had conductive/mixed hearing loss and two had single-sided deafness. METHODS: To define audibility, we needed to establish two things: (1) in situ-level thresholds at each audiometric frequency in force (skull simulator) and in sound pressure level (SPL; surface microphone). Next, we measured the responses of the preprogrammed test device in force on the skull simulator and in SPL on the surface mic in response to pink noise at three input levels: 55, 65, and 75 dB SPL. The skull simulator responses were converted to real head force responses by means of an individual real head to coupler difference transform. Subtracting the real head force level thresholds from the real head force output of the test aid yielded the audibility for each audiometric frequency for the skull simulator. Subtracting the SPL thresholds from the surface microphone from the SPL output of the test aid yielded the audibility for each audiometric frequency for the surface microphone. The surface microphone was removed and retested to establish the test-retest reliability of the tool. RESULTS: We ran a 2 (sensor) * 3 (input level) * 10 (frequency) mixed analysis of variance to determine if there were any significant main effects and interactions. There was a significant three-way interaction, so we proceeded to explore our planned comparisons. There were 90 planned comparisons of interest, three at each frequency (3 * 10) for the three input levels (30 * 3). Therefore, to minimize a type 1 error associated with multiple comparisons, we adjusted alpha using the Holm-Bonferroni method. There were five comparisons that yielded significant differences between the skull simulator and surface microphone (test and retest) in the estimation of audibility. However, the mean difference in these effects was small at 3.3 dB. Both sensors yielded equivalent results for the majority of comparisons. CONCLUSIONS: Models of bone conduction devices that have intact skin cannot be measured with the skull simulator. This study is the first to present and evaluate a new tool for bone conduction verification. The surface microphone is capable of yielding equivalent audibility measurements as the skull simulator for percutaneous bone conduction users at multiple input levels. This device holds potential for measuring other bone conduction devices (Sentio, BoneBridge, Attract, Soft headband devices) that do not have a percutaneous implant. PMID- 29578887 TI - Visual Performance and Perception as a Target of Saccadic Strategies in Patients With Unilateral Vestibular Loss. AB - OBJECTIVES: To evaluate the ability of saccadic strategies developed during vestibular compensation to reduce the effect of an impaired vestibulo-ocular reflex (VOR) on a retinal smear and image motion sensation. DESIGN: Twenty patients with unilateral vestibular loss were examined with a video head impulse test before and after vestibular rehabilitation (VR) with the use of gaze stabilization and refixation saccades training. Head and eye velocity functions were processed to infer the retinal eccentricity, and through its correlation with visual acuity (VA), several measurements are proposed to evaluate the influence of VR on saccades behavior and visual performance. To isolate the effect of saccades on the findings and avoid bias because of gain differences, only patients whose VOR gain values remained unchanged after VR were included. RESULTS: Improved contribution of covert saccades and reduction of overt saccades latency were measured after VR. We found significant differences when assessing both the interval less than 70% VA (50.25 ms), which is considered the limit of a moderate low vision, and less than 50% VA (39.515 ms), which is the limit for severe low vision. Time to recover a VA of 75% (near normal) was reduced in all the patients (median: 56.472 ms). CONCLUSION: Despite the absence of VOR gain improvement, patients with unilateral vestibular loss are able to develop saccadic strategies that allow the shortening of the interval of retinal smear and image motion. The proposed measurements might be of use to evaluate VR outcomes and visually induced impairment. PMID- 29578888 TI - Occupational Contact Dermatitis in the Canadian Aircraft Industry: A 25-Year Retrospective Study. AB - BACKGROUND: Aircraft building exposes workers to irritant and sensitizing products. OBJECTIVE: The aim of this article was to study occupational dermatoses among aircraft workers over 25 years. METHODS: The files of aerospace workers referred between 1990 and 2015 were extracted from the database of the McGill University Health Centre contact dermatitis clinic. These were subdivided according to demographics, type of work, patch testing results, and final diagnosis. RESULTS: Of 305 workers, 58% were 40 years or younger; one third were women. Onset of dermatitis varied from 2 months to 25 years, but 120 cases (39%) occurred during the first 3 years. Fifty-one percent of the cases involved assemblers, and 27% were composite material technicians, which were overrepresented as they constitute 10% of the workforce. Of the 305 workers, 152 suffered from allergic contact dermatitis, and 96 had irritant contact dermatitis. Of those with allergic contact dermatitis, 124 reacted to epoxy-based workplace products, but only 48 had positive patch tests to commercially available epoxy allergens. CONCLUSION: More than 60% of the cases of epoxy allergy would have been missed without testing with workplace products.

PMID- 29578890 TI - Static and Dynamic Pupillary Characteristics in Clinically Unilateral Pseudoexfoliation Syndrome. AB - PURPOSE: The purpose of this study was to perform a comparison of static and dynamic pupillometry measurements in patients with clinically unilateral pseudoexfoliation syndrome (PES) and age-matched controls. METHODS: This prospective cross-sectional study consisted of 38 patients with unilateral PES and 40 control participants. A quantitative pupillometry system was used to evaluate the pupil characteristics of eyes with PES (group 1), clinically unaffected fellow eyes (group 2), and healthy eyes (group 3). Static pupillometry measurements including scotopic pupil diameter (PD), mesopic PD, low photopic PD, and high photopic PD were undertaken. Subsequently, dynamic pupillometry measurements including resting diameter, amplitude of pupil contraction, latency of pupil contraction, duration of pupil contraction, velocity of pupil contraction, latency of pupil dilation, duration of pupil dilation, and velocity of pupil dilation were undertaken. RESULTS: There were statistically significant differences between the groups with regard to scotopic PD, mesopic PD, and low photopic PD (P<0.001). The pairwise comparisons exhibited that group 1 shows significantly lower PD values compared with groups 2 and 3. Group 2 also had significantly lower PD values compared with group 3. In addition, groups 1 and 2 had statistically significantly lower values of amplitude of pupil contraction, velocity of pupil contraction, duration of pupil dilatation, and velocity of pupil dilatation values compared with group 3. Moreover, group 1 and 2 demonstrated statistically significantly prolonged latency of pupil dilatation compared with group 3. CONCLUSIONS: Static and dynamic pupil characteristics of affected eyes and their fellow eyes of cases with unilateral PES are different from the healthy subjects. PMID- 29578891 TI - Diagnostic Abilities of the Optical Microangiography Parameters of the 3*3 mm and 6*6 mm Macular Scans in Glaucoma. AB - PURPOSE: To evaluate the diagnostic abilities of macular vessel length and perfusion densities measured with optical microangiography (OMAG) over a 3*3 mm and a 6*6 mm region, and to compare these with macular ganglion cell-inner plexiform layer (GCIPL) thickness in eyes with primary open-angle glaucoma (POAG). METHODS: In a cross-sectional study, 96 eyes of 57 control subjects and 88 eyes of 57 POAG patients underwent macular imaging with optical coherence tomography. Area under receiver operating characteristic curves (AUC) and sensitivities at 90% specificity of OMAG and GCIPL parameters were evaluated. RESULTS: Most OMAG parameters of the 3*3 mm macular scan and all inner sector parameters of the 6*6 mm scan were similar (P>0.05) in the POAG and control eyes. All outer sector OMAG parameters of the 6*6 mm scan were significantly less (P<0.05) in the POAG eyes. AUC and sensitivity at 90% specificity of the best parameter of the 3*3 mm OMAG scan (inner temporal vessel length density; 0.65% and 26%, respectively) were statistically similar (P>0.05) to that of the 6*6 mm scan (outer inferior vessel length density; 0.72% and 30%, respectively). AUC and sensitivity of the best GCIPL thickness parameter (inferotemporal GCIPL thickness, 0.84% and 67%) were significantly better (P<0.05) than that of the vessel length densities. CONCLUSIONS: The outer sector measurements of the 6*6 mm macular OMAG scans seem to be better than the inner sector measurements in diagnosing glaucoma. The GCIPL thickness measurements were significantly better than all macular OMAG parameters in diagnosing glaucoma.

PMID- 29578894 TI - Comparison of Placental and Neonatal Admission Complete Blood Cell Count and Blood Cultures. AB - BACKGROUND: The utilization of placental blood for neonatal admission laboratory tests, specifically the complete blood cell (CBC) count and blood culture, has the potential to delay the onset of anemia of prematurity and intraventricular hemorrhage, frequency of blood transfusions and associated complications, and painful procedures related to laboratory sampling. PURPOSE: To determine the feasibility of drawing neonatal admission laboratory tests from the placenta rather than the neonate and to compare CBC count and blood culture results. METHODS: All infants less than 35 weeks' gestational age and all term infants with a maternal history of chorioamnionitis or untreated, positive group B Streptococcus status were eligible to participate. Participating infants had paired CBC count and blood cultures obtained from the placenta and the infant. RESULTS: All CBC count outcomes were significantly, positively correlated between placental and infant blood (all Ps < .05). The paired white blood cells, neutrophils, and lymphocytes were strongly correlated (r = 0.761, r = 0.797, and r = 0.815, respectively), whereas the hemoglobin, hematocrit, platelet, and eosinophils were moderately correlated (r = 0.554, r = 0.545, r = 0.563, and r = 0.478, respectively). Monocytes and basophils were only weakly correlated (r = 0.373 and r = 0.217, respectively). There were 13 (93%) pairs where placental blood culture was positive but the direct infant draw blood culture was negative, and 1 (7%) pair where the placental culture was negative but the direct infant draw blood culture was positive. IMPLICATIONS FOR PRACTICE: The results of this and other studies suggest that placental blood can be reliably used to obtain neonatal admission CBC count and blood cultures. IMPLICATIONS FOR RESEARCH: Further research is needed regarding the prevention of blood culture contamination, especially in vaginally delivered placentas. Institutions that adopt this procedure should perform quality improvement initiatives to monitor outcomes and add to the growing body of literature on the utilization of placental blood for neonatal admission laboratory tests.

AB - Voxel phantoms developed by segmenting computed tomography images are known to be more anatomically accurate than mathematical phantoms. However, due to their lack of flexibility and the complexity of voxel datasets, the use of voxel phantoms in dosimetry is often impractical. This paper describes the development of the realistic anthropomorphic flexible (RAF) polygonal mesh phantom, a novel phantom based on Boundary Representation (B-Rep) that merges anatomical accuracy and flexibility. Rather than using segmentation of tomography images, the modeling of the phantom's organs was based on freely and commercially available anatomical atlases, ICRP 89, and recent medical literature. To validate the phantom, a high resolution voxel version was created for the MCNPx transport code. The voxelized RAF phantom was validated by comparing it with the ICRP 110 male phantom for external irradiations with parallel beams of photons and electrons. Dose coefficients obtained from simulations with the RAF phantom were compared with those from ICRP Publication 116. Relevant differences in organ doses were found. PMID- 29578898 TI - Reassessment of Resuspension Factor Following Radionuclide Dispersal: Toward a General-purpose Rate Constant. AB - A recent analysis of historical radionuclide resuspension datasets confirmed the general applicability of the Anspaugh and modified Anspaugh models of resuspension factors following both controlled and disastrous releases. While observations appear to have larger variance earlier in time, previous studies equally weighted the data for statistical fit calculations; this could induce a positive skewing of resuspension coefficients in the early time-period. A refitting is performed using a relative instrumental weighting of the observations. Measurements within a 3-d window are grouped into singular sample sets to construct standard deviations. The resulting best-fit equations produce tamer exponentials, which give decreased integrated resuspension factor values relative to those reported by Anspaugh. As expected, the fits attenuate greater error among the data at earlier time. The reevaluation provides a sharper contrast between the empirical models and reaffirms their deficiencies in the short-lived timeframe wherein the dynamics of particulate dispersion dominate the resuspension process. PMID- 29578899 TI - Saving Lives and Preventing Injuries From Unjustified Protective Actions-Method for Developing a Comprehensive Public Protective Action Strategy for a Severe NPP Emergency. AB - During the response to the Fukushima Daiichi nuclear power plant (FDNPP) emergency, about 50 patients died during or shortly after an evacuation when they were not provided with the needed medical support. In addition, it has been shown that during the FDNPP emergency there were increases in mortality rates among the elderly due to long-term dislocation as a result of evacuation and relocation orders and an inability to stay in areas where residents were advised to shelter for extended periods. These deaths occurred even though the possible radiation exposure to the public was too low to result in radiation-induced deaths, injuries, or a meaningful increase in the cancer rate, even if no protective actions had been taken. These problems are not unique to the FDNPP emergency and would be expected if the recommendations of many organizations were followed. Neither the International Commission on Radiological Protection (ICRP), the U.S. Nuclear Regulatory Commission (NRC) nor the U.S Environmental Protection Agency (EPA) adequately take into consideration in their recommendations and analysis the non-radiological health impacts, such as deaths and injuries, that could result from protective actions. Furthermore, ICRP, NRC, EPA, and the U.S. Department of Homeland Security (DHS) call for taking protective actions at doses lower than those resulting in meaningful adverse radiation-induced health effects and do not state the doses at which such effects would be seen. Consequently, it would be impossible for decision makers and the public to balance all the hazards both from radiation exposure and protective actions when deciding whether a protective action is justified. What is needed, as is presented in this paper, is a method for developing a comprehensive protective action strategy that allows the public, decision makers, and others who must work together to balance the radiological with the non-radiological health hazards posed by protective actions, and to counter the exaggerated fear of radiation exposure that could lead to taking unjustified protective actions and adverse psychological, sociological, and other effects. PMID- 29578900 TI - Joint American Nuclear Society and Health Physics Society Conference: Applicability of Radiation Response Models to Low Dose Protection Standards. AB - Seventy-five years after the Hanford Site was initially created as the primary plutonium production site for atomic weapons development under the Manhattan Project, the American Nuclear Society and the Health Physics Society are sponsoring a conference from 30 September through 3 October 2018, in Pasco, Washington, titled "Applicability of Radiation Response Models to Low Dose Protection Standards." The goal of this conference is to use current scientific data to update the approach to regulating low-level radiation doses; i.e., to answer a quintessential question of radiation protection-how to best develop radiation protection standards that protect human populations against detrimental effects while allowing the beneficial uses of radiation and radioactive materials. Previous conferences (e.g., "Wingspread Conference," "Arlie Conference") have attempted to address this question; but now, almost 20 y later, the key issues, goals, conclusions, and recommendations of those two conferences remain and are as relevant as they were then. Despite the best efforts of the conference participants and increased knowledge and understanding of the science underlying radiation effects in human populations, the bases of current radiation protection standards have evolved little. This 2018 conference seeks to provide a basis and path forward for evolving radiation protection standards to be more reflective of current knowledge and understanding of low dose response models.

AB - The U.S. Navy uses the Harshaw 8840/8841 dosimetric (DT-702/PD) system, which employs LiF:Mg,Cu,P thermoluminescent dosimeters (TLDs), developed and produced by Thermo Fisher Scientific (TFS). The dosimeter consists of four LiF:Mg,Cu,P elements, mounted in Teflon(r) on an aluminum card and placed in a plastic holder. The holder contains a unique filter for each chip made of copper, acrylonitrile butadiene styrene (ABS), Mylar(r), and tin. For accredited dosimetry labs, the ISO/IEC 17025:2005(E) requires an acceptance procedure for all new equipment. The Naval Dosimetry Center (NDC) has developed and tested a new non-destructive procedure, which enables the verification and the evaluation of embedded filters in the holders. Testing is based on attenuation measurements of low-energy radiation transmitted through each filter in a representative sample group of holders to verify that the correct filter type and thickness are present. The measured response ratios are then compared with the expected response ratios. In addition, each element's measured response is compared to the mean response of the group. The test was designed and tested to identify significant nonconformities, such as missing copper or tin filters, double copper or double tin filters, or other nonconformities that may impact TLD response ratios. During the implementation of the developed procedure, testing revealed a holder with a double copper filter. To complete the evaluation, the impact of the nonconformities on proficiency testing was examined. The evaluation revealed failures in proficiency testing categories III and IV when these dosimeters were irradiated to high-energy betas.

PMID- 29578907 TI - Technical Performance as a Predictor of Clinical Outcomes in Laparoscopic Gastric Cancer Surgery. AB - OBJECTIVE: The purpose of this study was to evaluate the relationship between technical performance and patient outcomes in laparoscopic gastric cancer surgery. BACKGROUND: Laparoscopic gastrectomy for cancer is an advanced procedure with high rate of postoperative morbidity and mortality. Many variables including patient, disease, and perioperative management factors have been shown to impact postoperative outcomes; however, the role of surgical performance is insufficiently investigated. METHODS: A retrospective review was performed for all patients who had undergone laparoscopic gastrectomy for cancer at 3 teaching institutions between 2009 and 2015. Patients with available, unedited video recording of their procedure were included in the study. Video files were rated for technical performance, using Objective Structured Assessments of Technical Skills (OSATS) and Generic Error Rating Tool instruments. The main outcome variable was major short-term complications. The effect of technical performance on patient outcomes was assessed using logistic regression analysis with backward selection strategy. RESULTS: Sixty-one patients with available video recordings were included in the study. The overall complication rate was 29.5%. The mean Charlson comorbidity index, type of procedure, and the global OSATS score were included in the final predictive model. Lower performance score (OSATS <=29) remained an independent predictor for major short-term outcomes (odds ratio 6.49), while adjusting for comorbidities and type of procedure. CONCLUSIONS: Intraoperative technical performance predicts major short-term outcomes in laparoscopic gastrectomy for cancer. Ongoing assessment and enhancement of surgical skills using modern, evidence-based strategies might improve short-term patient outcomes. Future work should focus on developing and studying the effectiveness of such interventions in laparoscopic gastric cancer surgery.

AB - OBJECTIVES: To establish an evidence-based cutoff to differentiate between early and late recurrence and to compare clinicopathologic risk factors between the two groups. SUMMARY BACKGROUND DATA: A clear definition of "early recurrence" after pancreatic ductal adenocarcinoma resection is currently lacking. METHODS: Patients undergoing pancreatectomy for pancreatic ductal adenocarcinoma between 2000 and 2013 were included. Exclusion criteria were neoadjuvant therapy and incomplete follow-up. A minimum P-value approach was used to evaluate the optimal cut-off value of recurrence-free survival to divide the patients into early and late recurrence cohorts based on subsequent prognosis. Potential risk factors for early recurrence were assessed with logistic regression models. RESULTS: Of 957 included patients, 204 (21.3%) were recurrence-free at last follow-up. The optimal length of recurrence-free survival to distinguish between early (n = 388, 51.5%) and late recurrence (n = 365, 48.5%) was 12 months (P < 0.001). Patients with early recurrence had 1-, and 2-year post-recurrence survival rates of 20 and 6% compared with 45 and 22% for the late recurrence group (both P < 0.001). Preoperative risk factors for early recurrence included a Charlson age comorbidity index >=4 (OR 1.65), tumor size > 3.0 cm on computed tomography (OR 1.53) and CA 19-9 > 210 U/mL (OR 2.30). Postoperative risk factors consisted of poor tumor differentiation grade (OR 1.66), microscopic lymphovascular invasion (OR 1.70), a lymph node ratio > 0.2 (OR 2.49), and CA 19-9 > 37 U/mL (OR 3.38). Adjuvant chemotherapy (OR 0.28) and chemoradiotherapy (OR 0.29) were associated with a reduced likelihood of early recurrence. CONCLUSION: A recurrence-free interval of 12 months is the optimal threshold for differentiating between early and late recurrence, based on subsequent prognosis. PMID- 29578910 TI - Multisource Evaluation of Surgeon Behavior is Associated with Malpractice Claims. AB - OBJECTIVE: We merged direct, multisource, and systematic assessments of surgeon behavior with malpractice claims, to analyze the relationship between surgeon 360 degree reviews and malpractice history. BACKGROUND: Previous work suggests that malpractice claims are associated with a poor physician-patient relationship, which is likely related to behaviors captured by 360-degree review. We hypothesize that 360-degree review results are associated with malpractice claims. METHODS: Surgeons from 4 academic medical centers covered by a common malpractice carrier underwent 360-degree review in 2012 to 2013 (n = 385). Matched, de-identified reviews and malpractice claims data were available for 264 surgeons from 2000 to 2015. We analyzed 23 questions, highlighting positive and negative behaviors within the domains of education, excellence, humility, openness, respect, service, and teamwork. Regression analysis with robust standard error was used to assess the potential association between 360-degree review results and malpractice claims. RESULTS: The range of claims among the 264 surgeons was 0 to 8, with 48.1% of surgeons having at least 1 claim. Multiple positive and negative behaviors were significantly associated with the risk of having malpractice claims (P < 0.05). Surgeons in the bottom decile for several items had an increased likelihood of having at least 1 claim. CONCLUSION: Surgeon behavior, as assessed by 360-degree review, is associated with malpractice claims. These findings highlight the importance of teamwork and communication in exposure to malpractice. Although the nature of malpractice claims is complex and multifactorial, the identification and modification of negative physician behaviors may mitigate malpractice risk and ultimately result in the improved quality of patient care. PMID- 29578911 TI - Adrenal Metastasectomy in the Presence and Absence of Extraadrenal Metastatic Disease. AB - OBJECTIVE: To determine if there are differences in overall survival (OS) or event-free survival (EFS) in patients with and without concomitant extra-adrenal metastases undergoing adrenal metastasectomy. BACKGROUND: There is growing interest in the use of local therapies in patients with oligometastatic disease. Previously published series have indicated that long-term survival is possible with resection. Adrenalectomy has been used to treat adrenal metastases in select patients. METHODS: Patients who underwent adrenal metastasectomy from 1994 to 2015 were identified from a prospectively maintained institutional database of adrenalectomy patients, excluding adrenalectomies due to tumor extension or for palliation. Sites of disease, treatment history, and survival data were extracted from chart review. RESULTS: One hundred seventy-four patients were included. Tumor histology included 68 nonsmall cell lung cancer, 34 renal cancer, 18 colorectal cancer, 11 melanoma cancer, 10 hepatocellular cancer, 8 sarcoma cancer, and 25 other cancers. The median follow-up among survivors was 5.2 (1-21) years. OS at 3 and 5 years was 50% and 40%, respectively. Patients with (n = 83) and without (n = 91) extra-adrenal metastases did not differ with respect to age, adrenal tumor size, or margin status. Median OS (3.3 years for patients with concomitant extra-adrenal metastases and 3.0 years for patients with isolated adrenal metastases; P = 0.816) and EFS (9.39 vs 9.59 months; P = 0.87) were similar. Factors negatively associated with OS included adrenal tumor size (P < 0.01), renal primary versus other (P < 0.01), and adrenal margin status (P < 0.01). CONCLUSIONS: In selected patients undergoing adrenal metastasectomy, there were no significant differences in OS or EFS between patients with and without concomitant extra-adrenal metastases. PMID- 29578913 TI - A Changing Landscape in Pancreatic Cancer. PMID- 29578912 TI - Stent Design Affects Femoropopliteal Artery Deformation. AB - BACKGROUND: Poor durability of femoropopliteal artery (FPA) stenting is multifactorial, and severe FPA deformations occurring with limb flexion are likely involved. Different stent designs result in dissimilar stent-artery interactions, but the degree of these effects in the FPA is insufficiently understood. OBJECTIVES: To determine how different stent designs affect limb flexion-induced FPA deformations. METHODS: Retrievable markers were deployed into n = 28 FPAs of lightly embalmed human cadavers. Bodies were perfused and CT images were acquired with limbs in the standing, walking, sitting, and gardening postures. Image analysis allowed measurement of baseline FPA foreshortening, bending, and twisting associated with each posture. Markers were retrieved and 7 different stents were deployed across the adductor hiatus in the same limbs. Markers were then redeployed in the stented FPAs, and limbs were reimaged. Baseline and stented FPA deformations were compared to determine the influence of each stent design. RESULTS: Proximal to the stent, Innova, Supera, and SmartFlex exacerbated foreshortening, SmartFlex exacerbated twisting, and SmartControl restricted bending of the FPA. Within the stent, all devices except Viabahn restricted foreshortening; Supera, SmartControl, and AbsolutePro restricted twisting; SmartFlex and Innova exacerbated twisting; and Supera and Viabahn restricted bending. Distal to the stents, all devices except AbsolutePro and Innova exacerbated foreshortening, and Viabahn, Supera, Zilver, and SmartControl exacerbated twisting. All stents except Supera were pinched in flexed limb postures. CONCLUSIONS: Peripheral self-expanding stents significantly affect limb flexion-induced FPA deformations, but in different ways. Although certain designs seem to accommodate some deformation modes, no device was able to match all FPA deformations. PMID- 29578914 TI - Understanding and Treating Supralevator Fistula-in-Ano: MRI Analysis of 51 Cases and a Review of Literature. AB - BACKGROUND: Supralevator fistulas are highly complex. The delineation of the supralevator fistula has become accurate because of MRI. OBJECTIVE: The aim of the study was to analyze the pathophysiology and treatment of different types of supralevator fistulas. DESIGN: This was a prospective study. SETTINGS: The study was conducted at a specialized fistula treatment center in North India. PATIENTS: All of the patients with fistula-in-ano who presented in the outpatient department were assessed with a physical examination and MRI scan. The patients in whom the supralevator extension was confirmed on MRI were included in the study. MAIN OUTCOME MEASURES: The MRI scans of patients included in the study were analyzed in detail to assess the types of supralevator fistulas and other characteristics of these fistulas. The patients who were operated on were followed for cure rate and deterioration in incontinence. RESULTS: Of 702 patients with fistula-in-ano who were analyzed by MRI over a period of 3 years, 51 patients with supralevator fistula-in-ano were identified. The mean age was 44.3 +/- 12.1 years and the male:female ratio was 16:1. The incidence of supralevator fistulas was 7.26% (51 of 702). In supralevator fistulas, the supralevator extension (upper part) was found to be in the intersphincteric plane in all of the patients. This upper part could be successfully managed by laying it open through the transanal route. The infralevator (lower) part could be of 3 types: intersphincteric (n = 13), low transsphincteric (n = 3), or high transsphincteric (n = 35). The lower part could be managed conventionally. There were no extrasphincteric fistulas. An extensive review of the literature revealed only 2 studies (total fistulas = 16) in which supralevator fistula was studied. LIMITATIONS: This was a retrospective study. CONCLUSIONS: The upper supralevator extension in all of the supralevator fistulas is almost always in the intersphincteric plane. This upper part could be laid open through the transanal route. The lower infralevator part could be of 3 types, intersphincteric, low transsphincteric, or high transsphincteric, which could be managed conventionally. Thus, supralevator fistulas could be managed successfully and easily. See Video Abstract at http://links.lww.com/DCR/A630.

AB - BACKGROUND: There has been a surge in clinical trials studying the safety and efficacy of mesenchymal stem cells for the treatment of perianal Crohn's disease. OBJECTIVE: The purpose of this work was to systematically review the literature to determine safety and efficacy of mesenchymal stem cells for the treatment of refractory perianal Crohn's disease. DATA SOURCES: Sources included PubMed, Cochrane Library Central Register of Controlled Trials, and Embase. STUDY SELECTION: Studies that reported safety and/or efficacy of mesenchymal stem cells for the treatment of perianal Crohn's disease were included. Two independent assessors reviewed eligible articles. INTERVENTION: The study intervention was delivery of mesenchymal stem cells to treat perianal Crohn's disease. MAIN OUTCOMES MEASURES: Safety and efficacy of mesenchymal stem cells used to treat perianal Crohn's disease were measured. RESULTS: Eleven studies met the inclusion criteria and were included in the systematic review. Three trials with a comparison arm were included in the meta-analysis. There were no significant increases in adverse events (OR = 1.07 (95% CI, 0.61-1.89); p = 0.81) or serious adverse events (OR = 0.53 (95% CI, 0.28-0.98); p = 0.04) in patients treated with mesenchymal stem cells. Mesenchymal stem cells were associated with improved healing as compared with control subjects at primary end points of 6 to 24 weeks (OR = 3.06 (95% CI, 1.05-8.90); p = 0.04) and 24 to 52 weeks (OR = 2.37 (95% CI, 0.90-6.25); p = 0.08). LIMITATIONS: The study was limited by its multiple centers and heterogeneity in the study inclusion criteria, mesenchymal stem cell origin, dose and frequency of delivery, use of scaffolding, and definition and time point of fistula healing. CONCLUSIONS: Although there have been only 3 trials conducted with control arms, existing data demonstrate improved efficacy and no increase in adverse or serious adverse events with mesenchymal stem cells as compared with control subjects for the treatment of perianal Crohn's disease. PMID- 29578918 TI - Elective Stoma Reversal Has a Higher Incidence of Postoperative Clostridium Difficile Infection Compared With Elective Colectomy: An Analysis Using the American College of Surgeons National Surgical Quality Improvement Program and Targeted Colectomy Databases. AB - BACKGROUND: Clostridium difficile infection is caused by the proliferation of a gram-positive anaerobic bacteria after medical or surgical intervention and can result in toxic complications, emergent surgery, and death. OBJECTIVE: This analysis evaluates the incidence of C difficile infection in elective restoration of intestinal continuity compared with elective colon resection. DESIGN: This was a retrospective database review of the 2015 American College of Surgeons National Surgical Quality Improvement Project and targeted colectomy database. SETTINGS: The intervention cohort was defined as the primary Current Procedural Terminology codes for ileostomy/colostomy reversal (44227, 44620, 44625, and 44626) and International Classification of Diseases codes for ileostomy/colostomy status (VV44.2, VV44.3, VV55.2, VV55.3, Z93.2, Z93.3, Z43.3, and Z43.2). PATIENTS: A total of 2235 patients underwent elective stoma reversal compared with 10403 patients who underwent elective colon resection. INTERVENTION: Multivariate regression modeling of the impact of stoma reversal on postoperative C difficile infection risk was used as the study intervention. MAIN OUTCOME MEASURES: The incidence of C difficile infection in the 30 days after surgery was measured. RESULTS: The incidence of C difficile infection in the 30-day postoperative period was significantly higher (3.04% vs 1.25%; p < 0.001) in patients undergoing stoma reversal. After controlling for differences in cohorts, regression analysis suggested that stoma reversal (OR = 2.701 (95% CI, 1.966 3.711); p < 0.001), smoking (OR = 1.520 (95% CI, 1.063-2.174); p = 0.022), steroids (OR = 1.677 (95% CI, 1.005-2.779); p = 0.048), and disseminated cancer (OR = 2.312 (95% CI, 1.437-3.719); p = 0.001) were associated with C difficile infection incidence in the 30-day postoperative period. LIMITATIONS: The study was limited because it was a retrospective database review with observational bias. CONCLUSIONS: Patients who undergo elective stoma reversal have a higher incidence of postoperative C difficile infection compared with patients who undergo an elective colectomy. Given the impact of postoperative C difficile infection, a heightened sense of suspicion should be given to symptomatic patients after stoma reversal.

AB - BACKGROUND: The incidence of colorectal cancer in the young (under age 40) is increasing, and this population has worse oncologic outcomes. Mucinous histology is a potential prognostic factor in colorectal cancer, but has not been evaluated specifically in young patients. OBJECTIVE: The objective of the study was to determine factors associated with poor outcome in young patients with colorectal cancer (<=40 years) and to determine relationships between mucinous histology and oncologic outcomes in this population. DESIGN: This is a retrospective study. SETTING: Patients from a single-institution tertiary care center were studied. PATIENTS: A total of 224 patients with colorectal cancer under 40 years of age diagnosed between 1990 and 2010 were included (mean age, 34.7 years; 51.3% female). 34 patients (15.2%) had mucinous histology. INTERVENTIONS(S): There were no interventions. MAIN OUTCOME MEASURES: Oncologic outcomes were analyzed according to the presence of mucinous histology. RESULTS: The mucinous and nonmucin colorectal cancer study populations were statistically similar in age, sex, tumor location, pathological stage, differentiation, and adjuvant chemotherapy use. Five-year disease-free survival was 29.1% versus 71.3% (p < 0.0001) and 5-year overall survival was 54.7% versus 80.3% (p < 0.0001) for mucinous and nonmucinous patients, respectively. Mucinous colorectal cancers recurred earlier at a median time of 36.4 months versus 94.2 months for nonmucin colorectal cancers (p < 0.001). On multivariate analysis, pathological stage (stage II HR, 3.61; 95% CI, 1.37-9.50; stage III HR, 5.27; 95% CI, 2.12-12.33), positive margins (HR, 1.95; 95% CI, 1.12-3.23), angiolymphatic invasion (HR, 2.15; 95% CI, 1.26-3.97), and mucinous histology (HR, 2.36; 95% CI, 1.44-3.96) were independently associated with worse disease-free and overall survival. LIMITATIONS: This is a retrospective study without genetic information. CONCLUSIONS: Mucinous histology is a negative prognostic factor in young patients with colorectal cancer. This is associated with early and high recurrence rates, despite use of standard neoadjuvant and adjuvant regimens. Physicians need to be aware of this association and potentially explore novel treatment options. See Video Abstract at http://links.lww.com/DCR/A575. PMID- 29578920 TI - Open Surgical Incisions After Colorectal Surgery Improve Quality Metrics, But Do Patients Benefit? AB - BACKGROUND: Surgical site infection is a frequent cause of morbidity after colorectal resection and is a quality measure for hospitals and surgeons. In an effort to reduce the risk of postoperative infections, many wounds are left open at the time of surgery for secondary or delayed primary wound closure. OBJECTIVE: The purpose of this study was to evaluate the impact of delayed wound closure on the rate of surgical infections and resource use. DESIGN: This retrospective propensity-matched study compared colorectal surgery patients with wounds left open with a cohort of patients with primary skin closure. SETTINGS: The American College of Surgeons National Quality Improvement Program Participant Use file for 2014 was queried. PATIENTS: A total of 50,212 patients who underwent elective or emergent colectomy, proctectomy, and stoma creation were included. MAIN OUTCOME MEASURES: Rates of postoperative infections and discharge to medical facilities were measured. RESULTS: Surgical wounds were left open in 2.9% of colorectal cases (n = 1466). Patients with skin left open were broadly higher risk, as evidenced by a significantly higher median estimated probability of 30-day mortality (3.40% vs 0.45%; p < 0.0001). After propensity matching (n = 1382 per group), there were no significant differences between baseline characteristics. Within the matched cohort, there were no differences in the rates of 30-day mortality, deep or organ space infection, or sepsis (all p > 0.05). Resource use was higher for patients with incisions left open, including longer length of stay (11 vs 10 d; p = 0.006) and higher rates of discharge to a facility (34% vs 27%; p < 0.001). LIMITATIONS: This study was limited by its retrospective design and a large data set with a bias toward academic institutions. CONCLUSIONS: In a well matched colorectal cohort, secondary or delayed wound closure eliminates superficial surgical infections, but there was no decrease in deep or organ space infections. In addition, attention should be given to the possibility for increased resource use associated with open surgical incisions. See Video Abstract at http://links.lww.com/DCR/A560. PMID- 29578921 TI - Updated clinical indications for transcatheter aortic valve implantation in patients with severe aortic stenosis: expert opinion of the Italian Society of Cardiology and GISE. AB - : The introduction of percutaneous treatment of severe aortic stenosis with transcatheter aortic valve implantation (TAVI) remains one of the greatest achievements of interventional cardiology. In fact, TAVI emerged as a better option than either medical therapy or balloon aortic valvuloplasty for patients who cannot undergo surgical aortic valve replacement (SAVR) or are at high surgical risk. Recently, increased operator experience and improved device systems have led to a worldwide trend toward the extension of TAVI to low-risk or intermediate-risk patients. In this expert opinion paper, we first discuss the basic pathophysiology of aortic stenosis in different settings then the key results of recent clinical investigations on TAVI in intermediate-risk aortic stenosis patients are summarized. Particular emphasis is placed on the results of the nordic aortic valve intervention, placement of aortic transcatheter valves (PARTNER) 2 and Surgical Replacement and Transcatheter Aortic Valve Implantation Randomized trials. The PARTNER 2 was the first large randomized trial that evaluated the outcome of TAVI in patients at intermediate risk. The PARTNER 2 data demonstrated that TAVI is a feasible and reasonable alternative to surgery in intermediate-risk patients (Society of Thoracic Surgeons 4-8%), especially if they are elderly or frail. There was a significant interaction between TAVI approach and mortality, with transfemoral TAVI showing superiority over SAVR. Moreover, we examine the complementary results of the recently concluded Surgical Replacement and Transcatheter Aortic Valve Implantation trial. This prospective randomized trial demonstrated that TAVI is comparable with surgery (primary end point 12.6% in the TAVI group vs. 14.0% in the SAVR group) in severe aortic stenosis patients deemed to be at intermediate risk. We review the most relevant clinical evidence deriving from nonrandomized studies and meta-analyses. Altogether, clinical outcome available data suggest that TAVI with a newer generation device might be the preferred treatment option in this patient subgroup. Finally, the differences between the latest European and American Guidelines on TAVI were reported and discussed. The conclusion of this expert opinion article is that TAVI, if feasible, is the treatment of choice in patients with prohibitive or high surgical risk and may lead to similar or lower early and midterm mortality rates compared with SAVR in intermediate-risk patients with severe aortic stenosis.

PMID- 29578924 TI - Sickle Cell Disease is Associated With Elevated Levels of Skin Advanced Glycation Endproducts. AB - Sickle cell disease (SCD) is associated with increased oxidative stress which potentially enhances generation of advanced glycation endproducts (AGEs). We estimated skin accumulation of AGEs in SCD patients and assessed their relationship with hemolysis and nephropathy. Skin intrinsic fluorescence (SIF), an estimate of AGEs, was assessed in African American patients with and without SCD. After skin excitation with light at 375, 405, and 420 nm, raw autofluorescence was adjusted using specific intrinsic corrections. Group differences in SIF were evaluated by multiple variable regression using chronological age and sex as covariates. The relationship of SIF with reticulocyte count, serum lactate dehydrogenase, estimated glomerular filtration rate (GFR), plasma creatinine, bilirubin, and urine microalbumin was assessed. There were 48 SCD patients (29 male/19 female, age=13.4+/-3.6 y) and 51 controls (25 male/26 female, age=10.4+/-5.0 y). SIF375(1.0,0.0), SIF405(0.5,0.5), and SIF420(0.5,0.5) were significantly higher in SCD patients. There was no difference in SIF between SCD patients with and without microalbuminuria. SIF 420(0.5,0.5) was correlated with reticulocyte count (r=0.33; P=0.03). Skin AGEs as estimated by SIF were higher in children with SCD and weakly associated with 1 measure of hemolysis. Further study is needed to determine whether chronic increased deposition of AGEs is associated with development of complications of SCD. PMID- 29578925 TI - Successful Management of a Rare Cause of Hemolytic Uremic Syndrome With Eculizumab in a Child. AB - BACKGROUND: Hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia. It very rarely coexists with acute lymphoblastic leukemia (ALL) emerging before, simultaneously, or after the diagnosis has been made, and management of the patient may be difficult. CASE: We present the case of a 7-year-old boy who was diagnosed with HUS and initially managed by hemodialysis (HD). Thereafter, HUS progressed, and neurological findings developed. The patient was treated with eculizumab, agressive blood pressure control, and antiepileptic drugs. At the fifth month of follow-up, the patient was diagnosed with acute B-cell lymphoblastic leukemia with fever, bone pain, hepatosplenomegaly, and pancytopenia. After initiation of ALL treatment, he had no episodes of HUS, despite cessation of eculizumab. CONCLUSION: In conclusion, eculizumab may be a treatment of choice to prevent further systemic damage in recurrent HUS episodes of patients with borderline changes in the bone marrow until ALL is constantly diagnosed. PMID- 29578926 TI - Altered white matter microstructure associated with mild and moderate depressive symptoms in young adults, a diffusion tensor imaging study. AB - In the context of growing evidence supporting disturbed neural connectivity in the pathogenesis of depressive symptoms, we used the diffusion tensor imaging technique to investigate white matter disruptions in previously undiagnosed and hence treatment-naive young adults with mild and moderate depressive symptoms screened by Beck's Depression Inventory test compared with age-matched and sex matched healthy controls. This is the first diffusion tensor imaging study to assess minor forms of depression. We hypothesized that subthreshold depressive symptoms share the same neural disruptions as major depressive disorder (MDD). Each group included 47 participants with a mean age of 20.1+/-1.1 years. The exploratory region of interest method was used to assess integrity (fractional anisotropy and mean diffusivity) in 48 regions of the brain based on Mori atlas. Data were recruited from the Southwest University Longitudinal Imaging Multimodal Brain Data Repository. The following pathways showed significant microstructural changes by means of reduced fractional anisotropy in the group with depressive symptoms compared with normal participants: pontine crossing tract; genu of the corpus callosum; posterior limb of the internal capsule (bilaterally); and anterior, posterior, and superior corona radiata (bilaterally). None of the above regions, but the middle cerebellar peduncle and the right superior fronto occipital fasciculus were shown to differ significantly in the mean diffusivity values between the two groups. On the basis of the current results, our findings provide evidence that the white matter impairments in the interhemispheric connections and frontal-subcortical neural circuits may play a key role in the pathogenesis of depression in young adults. The similarity of neural underpinnings in MDD and minor depressive disorder in this study further proves that these two mood disorders exist in a continuum, and milder depressive symptoms can herald a major episode. Besides the high prevalence and great burden of subthreshold forms of depression on personal and social aspects of life, there is lack of knowledge of them and most studies have mainly focused on MDD. This study provides a new avenue in addressing neuropathology of depression, mainly in subtle forms that are almost always overlooked. PMID- 29578927 TI - Minimal starting time of data reconstruction for qualitative myocardial perfusion rubidium-82 positron emission tomography imaging. AB - OBJECTIVE: Qualitative positron emission tomography (PET) myocardial perfusion imaging (MPI) scans are reconstructed with a delay after an injection of rubidium 82 (Rb) to ensure blood pool clearance and sufficient left ventricle to myocardium contrast. Our aim was to derive the minimal starting time of data reconstruction (STDR) after an injection of Rb for which the diagnostic value and image quality remained unaffected. MATERIALS AND METHODS: We retrospectively included 23 patients who underwent rest-stress Rb PET MPI using 740 MBq. Patients fulfilling one of the two criteria indicating a slow blood pool clearance (ejection fraction <50% and/or cardiac output <3 l/min) were included in a consecutive manner. PET images using five different STDRs (1:15-2:15 min) were reconstructed and compared with reference images (STDR of 2:30 min). Differences in the summed rest score greater than or equal to 3 and total perfusion deficit greater than 3% were considered to significantly influence the diagnostic value. In addition, image quality was scored by two experts as not interpretable, inferior, adequate, or excellent. RESULTS: The summed rest score differed greater than or equal to 3 from the reference in seven or more patients (>=30%) using STDR less than or equal to 2:00 min (P<0.02). STDR less than or equal to 1:30 min resulted in six or more patients (>=26%) with a total perfusion deficit difference greater than 3% (P<0.03).In addition, STDR less than or equal to 2:00 min resulted in a lower image quality (P<0.002) and STDR less than or equal to 2:15 min resulted in greater than or equal to two scans with noninterpretable image quality. CONCLUSION: STDR less than or equal to 2:15 min resulted in lower diagnostic value or insufficient image quality for qualitative PET MPI using 740 MBq Rb. An STDR of 2:30 min can be considered for clinical adoption. PMID- 29578928 TI - Negative correlation of high-density of lipoprotein-cholesterol and bone mineral density in postmenopausal Iranian women with vitamin D deficiency. AB - OBJECTIVE: The aim of the study was to investigate the association between high density lipoprotein (HDL) and bone status taking into account serum vitamin D levels in postmenopausal Iranian women. METHODS: During January 2015 and February 2016, a total of 488 postmenopausal Iranian women participated in this cross sectional study, all of whom were not taking osteoporosis medication and were not suffering from any chronic disorder. Dual X-ray absorptiometry was used to assess bone mineral density (BMD) of the total hip, femoral neck, and lumbar vertebrae (L2-L4). Each person was categorized based on the World Health Organization osteoporosis criteria in at least one skeletal region. At the end of the data collection, lipid profiles and vitamin D levels were measured for all participants. Vitamin D serum levels less than 30 ng/mL were defined as vitamin D deficiency or insufficiency. RESULTS: 27.9% of all participants displayed osteoporosis. Osteoporotic participants tended to be older with higher HDL serum levels (P < 0.001). No significant difference was seen in low-density of lipoprotein, total triglyceride, and total cholesterol levels among participants (P > 0.05). In a univariate model, after adjusting for age, menopausal age, obesity, physical activity, and use of antihyperlipidemic drugs (statins), there were significant negative associations among HDL levels and BMD values and T score in the three regions (P < 0.004). Interestingly, after classification of participants based on vitamin D levels and adjustment for confounding factors, these significant negative associations between HDL levels and BMD values as well as T-score were observed only in participants with vitamin D deficiency or insufficiency, in the three regions (P < 0.008). CONCLUSIONS: Our data show that in postmenopausal women with vitamin D deficiency, serum levels of HDL have negative correlation with bone status. PMID- 29578929 TI - The Factors Affecting Teaching and Learning Professionalism Among Medical Teachers. AB - Given the special importance of medical professionalism, a successful faculty development strategy not only teaches professionalism in cognitive domain but also creates practical instructors who can act as role models for students. This study proposed to identify themes that can explain effective factors in teaching and learning professionalism among medical teachers. The study was qualitative. Twenty-four experts in medical education participated in the study from all medical universities of Iran. Data gathering was performed via semistructured interviews. Interviews were transcribed and analyzed by classic content analysis. At the end, the factors were confirmed by the focus group consisting of six experts. One hundred seventy-seven codes were extracted. Codes were categorized into 24 subcategories and five main categories: (1) culture, (2) educational factors, (3) background, (4) attitude, and (5) organizational factors. There are many effective factors for a proper faculty development in teaching and learning professionalism. These factors could be individualized, organizational, or external. We cannot design a program without considering these factors. PMID- 29578930 TI - Interpersonal Conflict and Organizational Commitment Among Licensed Practical Nurses. AB - The shortage of nursing professionals in the United States is unquestionable. This shortage, which is predicted to continue into the foreseeable future, is a particularly salient problem within the nursing profession. This is especially true for long-term care facility administrators who not only are faced with the challenge of increasing numbers of aging residents but also regularly struggle with turnover among more cost-effective nursing staff, such as licensed practical nurses (LPNs). The primary purpose of this study was to examine whether perceived interpersonal conflict influences organizational commitment among LPNs. To accomplish this, we analyzed responses from 1165 LPNs throughout a Midwestern state who were queried on their perceptions of interpersonal conflict and organizational commitment in their work settings. Considering a wide range of potential confounding influences such as age and years working as an LPN, for example, we found that higher perceived interpersonal conflict was associated with significantly lower levels of organizational commitment. The implications of these findings, along with recommendations for nurse administrators to reduce LPN turnover, are discussed in the article. PMID- 29578931 TI - Contributors to Operating Room Underutilization and Implications for Hospital Administrators. AB - Operating rooms (ORs) are an important source of hospital revenue, and utilization rate is a key determinant of OR efficiency. Multiple factors contribute to OR underutilization, and OR managers may have biased views about which factors contribute most to OR underutilization. We examined various factors leading to OR underutilization at one academic tertriary care center.Data were collected retrospectively from over a 12-month period. Contribution to OR underutilization was measured in terms of hours of OR underutilization. Statistical significance between categories and days was calculated using an unpaired t test.By comparing means of the various contributors to OR underutilization (patient in the room, turnover time, scheduling gaps, OR holds, closed rooms), we determined that mid/end-of-day gaps and closed rooms contributed the most hours (9.7% and 4.6%, respectively; P < .0001) to OR underutilization, whereas turnover time and "patient in the room" contributed the least (2.0% and 0.8%, respectively; P < .0001).The contributors to OR underutilization are complex, and many OR staff from physicians to nurses and OR administrators may have biased views about which factors contribute most predominantly to inefficiency. Awareness of how various factors contribute to OR underutilization can pave the way for goal-directed changes on a systems-based level to improve efficiency in the OR by decreasing underutilization. PMID- 29578933 TI - Complex iatrogenic clubfoot: is it a real entity? AB - In our study, we aimed to demonstrate whether a complex iatrogenic clubfoot really exists; identify the causative mechanisms; and determine the outcome if properly treated. We observed 54 clubfeet previously treated unsuccessfully by manipulation and casting elsewhere. All the feet had been classified at diagnosis as typical clubfeet. In 26 cases, the cast had slipped down, entrapping the foot in a plantar-flexed position. Nine clubfeet out of those 26 cases presented the clinical features of a complex iatrogenic deformity. These were treated with the modified Ponseti protocol and evaluated at follow-up according to the International Clubfoot Study Group Score. The length of follow-up averaged 7.2 years. Two feet showed an excellent result, five feet showed a good result, and two feet showed a fair result. The relapse rate was 55% in complex clubfeet. Relapsed clubfeet were treated by Achilles tenotomy or lengthening and anterior tibial tendon transfer. We believe that faulty manipulation and a poor casting technique may convert a typical clubfoot into a complex iatrogenic deformity. Risk factors include severe clubfoot, short and stubby foot, and unmolded casts slipping down. PMID- 29578934 TI - Universal versus selective ultrasound screening for developmental dysplasia of the hip: a single-centre retrospective cohort study. AB - A total of 28 068 infants were studied to investigate whether universal ultrasound screening for developmental dysplasia of the hip results in fewer delayed presentations than selective screening, and whether the screening protocol affects subsequent treatment. The rate of delayed presentation was not lower with selective screening compared with universal screening but all cases of delayed presentation in this cohort were administrative errors. There were no sonographic errors (false-negatives). The treatment rate was significantly higher with universal screening but infants were treated earlier and were significantly less likely to require any surgical intervention. Those requiring surgery were less likely to require open reduction or pelvic osteotomy. PMID- 29578932 TI - Carotid Artery Stiffness and Cognitive Decline Among Women With or at Risk for HIV Infection. AB - BACKGROUND: Vascular stiffness is associated with aging and cognitive impairment in older populations without HIV. HIV has been linked to increased vascular stiffness. We examined whether vascular stiffness relates to cognitive decline at younger ages in women with or at risk for HIV. METHODS: We evaluated the association of carotid artery stiffness with decline in neuropsychological test performance among participants in the Women's Interagency HIV Study and assessed whether HIV modified the association. Baseline carotid stiffness, defined by the distensibility index, was determined at a single visit using carotid artery ultrasound. Longitudinal neuropsychological testing from 2004-2016 included Trail Making Tests A and B and the Symbol Digit Modalities Test. Relationships were assessed with linear mixed-effect models adjusted for demographic, behavioral, cardiometabolic, and neuropsychological factors. RESULTS: Among 1662 women (1192 [72%] HIV+), median baseline age was 41 years (interquartile range 34-47), with 60% non-Hispanic black and 28% Hispanic. Lower baseline distensibility (greater carotid stiffness) was associated with greater decline in neuropsychological test scores over 10-year follow-up as measured by Symbol Digit Modalities Test (adjusted beta = -0.06 per SD, P < 0.001), Trail Making Test A (beta = -0.08 per SD; P < 0.001), and Trail Making Test B (beta = -0.08 per SD; P < 0.001). Changes in cognitive function did not differ by HIV serostatus, or HIV-related factors. CONCLUSIONS: Higher carotid stiffness was independently associated with faster decline in executive functioning, information processing, and psychomotor speed even in mostly middle-aged minority women and regardless of HIV serostatus. Our study highlights the need for cardiovascular risk factor modification to prevent premature cognitive deterioration in this at-risk population. PMID- 29578935 TI - PENETRATING OCULAR INJURY WITH RETAINED INTRAOCULAR FOREIGN BODY FROM DRYWALL. AB - PURPOSE: To present a case of open globe injury and retained intraocular foreign body secondary to drywall. METHODS: Interventional case report. RESULTS: A 21 year-old man presented with corneal laceration, iris defect, and vitreous hemorrhage after hammering drywall. Computed tomography scan was negative for intraocular foreign body, but a drywall intraretinal foreign body was found on 25 gauge vitrectomy. Intraoperative findings and 6-month follow-up are presented. CONCLUSION: Intraocular foreign body must always be suspected in all cases of penetrating ocular trauma. Although magnetic resonance imaging is ideal in diagnosing nonmetallic foreign bodies, computed tomography scan with Hounsfield units should be used in an emergency setting. PMID- 29578936 TI - Mathematical Representation of Standard Kt/V Including Ultrafiltration and Residual Renal Function. AB - A new formula for calculating standard Kt/V from clinical data has been derived mathematically. It is based on using the relation between eKt/V and the pre- and postdialysis concentrations in order to find the steady state concentrations. The resulting expression for standard Kt/V depends on the treatment schedule (number, length, and spacing of treatments), residual renal function, and eKt/V and relative ultrafiltration volume of each individual treatment. These results include the effects of ultrafiltration and residual renal function also in the case with unequal treatments that may be arbitrarily distributed over the week. The new formula is found to agree, within small fractions of a percentage, with standard Kt/V from simulations of 3 and 5 days per week schedules. Several approximations are also suggested and their accuracies analyzed. It is shown that the use of the midweek eKt/V and ultrafiltration for all treatments of the week is an acceptable approximation. In the presence of residual renal function, the timing of the treatments is an important factor, and particularly in this case, the new formula shows improved accuracy over previously published formulas. PMID- 29578937 TI - Determination of Tacrolimus Concentration and Protein Expression of P Glycoprotein in Single Human Renal Core Biopsies. AB - BACKGROUND: Tacrolimus (TAC) is currently the cornerstone of immunosuppressive protocols for renal transplant recipients. Despite therapeutic whole blood monitoring, TAC is associated with nephrotoxicity, and it has been hypothesized that intrarenal accumulation of TAC and/or its metabolites are involved. As TAC is a substrate of P-glycoprotein (P-gp), the expression and activity of this efflux transporter could influence the levels of TAC in renal tissue. The primary aim of this study was to develop and validate a method for quantification of TAC in tissue homogenates from single human renal core biopsies. The secondary aim was to provide measures of P-gp expression and of the demethylated metabolites of TAC in the same renal biopsy. METHODS: Human renal tissue, with and without clinical TAC exposure, was used for method development and validation. Homogenates were prepared with bead-beating, and concentrations of TAC and its demethylated metabolites were analyzed with liquid chromatography tandem mass spectrometry after protein precipitation. A Western blot method was used for semiquantification of P-gp expression in the homogenates. The final methods were applied to renal core biopsies from 2 transplant patients. RESULTS: The TAC assay showed within- and between-run mean accuracy between 99.7% and 107% and coefficients of variation <=6.7%. Matrix effects were nonsignificant, and samples were stable for 3 months preanalytically when stored at -80 degrees C. TAC concentrations in the renal core biopsies were 62.6 and 43.7 pg/mg tissue. The methods for measurement of desmethyl-TAC and P-gp expression were suitable for semiquantification in homogenates from renal core biopsies. CONCLUSIONS: These methods may be valuable for the elucidation of the pharmacokinetic mechanisms behind TAC-induced nephrotoxicity in renal transplant recipients. PMID- 29578938 TI - Quantification of Apixaban, Dabigatran, Edoxaban, and Rivaroxaban in Human Serum by UHPLC-MS/MS-Method Development, Validation, and Application. AB - BACKGROUND: Direct oral anticoagulants (DOACs) are prescribed for anticoagulation in patients with atrial fibrillation and venous thromboembolic disease. Fixed doses are recommended, but measuring their serum drug concentrations as a basis for dose adjustments may be useful in some clinical settings. METHODS: An ultra high-performance liquid chromatography-tandem mass spectrometry method for the analysis of the DOACs apixaban, dabigatran, edoxaban, and rivaroxaban in human serum was developed and validated. A 100-uL serum sample was handled using a pipetting robot. Protein precipitation was performed with 375 uL of 1% formic acid in acetonitrile (vol/vol), and phospholipid removal was performed using a Waters Ostro 96-well plate. The injection volume was 1 uL, and run time was 3.0 minutes. RESULTS: The calibration range was 5-800 nmol/L. The between-day precision relative SDs were in the range of 3.3%-10%. Recoveries ranged from 85% to 105%, and matrix effects from 88% to 102%, when corrected with internal standard. Edoxaban was, in contrast to the other DOACs, unstable when stored for more than 6 hours at 30 degrees C. The suitability of the method was demonstrated by analyzing routine samples from 345 patients undergoing anticoagulation treatment. CONCLUSIONS: The developed method fulfilled the set validation criteria, and its suitability was demonstrated in a routine setting. The instability of edoxaban may complicate the transport of routine samples to the laboratory. PMID- 29578939 TI - Diminished Dynamic Physical Performance Is Associated With Orthostatic Hypotension in Geriatric Outpatients. AB - BACKGROUND AND PURPOSE: Orthostatic hypotension (OH), a blood pressure drop after postural change, is a highly prevalent and disabling syndrome in older adults. Yet, the association between physical performance and OH is not clearly established. The aim of this study was to determine whether different types of physical performance are associated with OH in a clinically relevant population of geriatric outpatients. METHODS: This cross-sectional study included 280 geriatric outpatients (mean age: 82.2 years, standard deviation: 7.1). Orthostatic hypotension was determined using intermittently measured blood pressure and continuously measured blood pressure in a random subgroup of 58 patients. Physical performance was classified into a dynamic type (4-m Walk Test, Chair Stand Test, and Timed Up and Go test) and a static type (standing balance tests, handgrip strength). Associations were analyzed using logistic regression models with adjustments for age, sex, weight, and height. RESULTS: Diminished physical performance on the Chair Stand Test was associated with OH measured intermittently. Diminished physical performance on all dynamic physical domains (4-m Walk Test, Chair Stand Test, and Timed Up and Go test) was associated with OH measured continuously. Static physical performance was not significantly associated with OH. CONCLUSION: Dynamic physical performance tests with a substantial postural change and center of mass displacement were significantly associated with OH. The influence of physical performance on OH in daily routine activities should be further explored to establish counteracting interventions. PMID- 29578940 TI - RELATIONSHIP OF CLINICAL FEATURES AND BASELINE TUMOR SIZE WITH GENE EXPRESSION PROFILE STATUS IN UVEAL MELANOMA: A Multi-institutional Study. AB - PURPOSE: To study the relationship between gene expression profile subclass and clinical features in a multicenter cohort of patients with uveal melanoma. METHODS: A retrospective, multicenter study was undertaken with patients entered from nine major ocular oncology centers from across the United States. Eligible patients had uveal melanoma and underwent I-125 plaque brachytherapy with concurrent tumor biopsy with gene expression profile testing between January 1, 2010, and October 28, 2014. Data were collected regarding patient demographics, baseline tumor clinical features, and gene expression profile results. Statistical analyses were performed using the Fisher's exact test, Wilcoxon rank sum test, Kruskal-Wallis test, and proportional-odds cumulative logit modeling. RESULTS: Inclusion criteria were met for 379 patients. Gene expression profile class divided the cohort into two main groups, Class 1 (n = 263) and Class 2 (n = 113). Class 1 tumors were further subdivided into Class 1a (n = 186) and Class 1b (n = 77). The differences between Class 1 and Class 2 tumors were similar to previous studies, except the finding of Class 2 tumors being more likely to have associated exudative retinal detachment (P < 0.001). There was no statistically significant difference between Class 1 and Class 2 tumors based on the presence of lipofuscin, drusen, or subretinal fluid. Class 1a tumor patients, compared with Class 1b, were significantly older (P = 0.034). Class 2 tumors, when compared with Class 1b, were associated with increasing patient age (P < 0.001), larger tumor height (P = 0.010), ciliary body involvement (P = 0.001), exudative retinal detachment (P = 0.024), and anterior tumor location (P < 0.001). When the tumors were grouped into Collaborative Ocular Melanoma Study size categories, increasing tumor size category was significantly associated with Class 2 status: 6% of small tumors, 32% of medium tumors, and 53% of large tumors were Class 2. CONCLUSION: In a multi-institutional setting, we found that the only significant difference in clinical features between Class 1a and Class 1b tumors was that patients with Class 1a tumors were older at the time of diagnosis. We also found that Class 1a and Class 1b have clinical features distinct from Class 2 tumors. The distribution of the gene expression profile subclasses among the size groups was similar to reported time-to-metastasis data among the same size groupings. Our clinical findings support the current molecular classification-based survival data previously reported in uveal melanoma. PMID- 29578941 TI - Reply. PMID- 29578944 TI - Efficacy of the Nav1.7 blocker PF-05089771 in a randomised, placebo-controlled, double-blind clinical study in subjects with painful diabetic peripheral neuropathy. AB - The effect of PF-05089771, a selective, peripherally restricted Nav1.7 sodium channel blocker on pain due to diabetic peripheral neuropathy was investigated in a randomised, placebo and active-controlled parallel group clinical trial (NCT02215252). A 1-week placebo-run in the period was followed by a 4-week treatment period and a 1-week placebo run-out/taper-down period. Single-blind placebo was administered throughout run-in and run-out periods. Subjects were randomised to receive either PF-05089771 150 mg twice daily, pregabalin 150 mg twice daily, or placebo during the 4-week treatment period. One hundred thirty five subjects were randomised. The primary endpoint was the average pain score derived from subjects' Numerical Rating Scale scores over the past 7 days of week 4 of the double-blind treatment period. Predefined efficacy criteria for the trial were the effect of PF-05089771 being >0.5 units better than placebo at interim analysis after completion of the first part of the study. Although a trend for a reduction in the weekly average pain score in the PF-05089771 treatment group was observed, this was not statistically significant when compared with placebo at week 4, with a mean posterior difference of -0.41 (90% credible interval: -1.00 to 0.17). The effect of PF-05089771 was smaller than that seen with pregabalin, which was statistically significant when compared with placebo at week 4, with a mean posterior difference of -0.53 (90% credible interval: -0.91 to -0.20). As predefined efficacy criteria were not met, the study did not proceed to the second part. PF-05089771 was well tolerated. Possible reasons for the modest efficacy observed with PF-05089771 are discussed. PMID- 29578943 TI - Wind-up in lamina I spinoparabrachial neurons: a role for reverberatory circuits. AB - Wind-up is a frequency-dependent increase in the response of spinal cord neurons, which is believed to underlie temporal summation of nociceptive input. However, whether spinoparabrachial neurons, which likely contribute to the affective component of pain, undergo wind-up was unknown. Here, we addressed this question and investigated the underlying neural circuit. We show that one-fifth of lamina I spinoparabrachial neurons undergo wind-up, and provide evidence that wind-up in these cells is mediated in part by a network of spinal excitatory interneurons that show reverberating activity. These findings provide insight into a polysynaptic circuit of sensory augmentation that may contribute to the wind-up of pain's unpleasantness.

AB - Sickle cell disease (SCD) is a chronic inflammatory disorder accompanied by chronic pain. In addition to ongoing pain and hyperalgesia, vaso-occlusive crises induced pain can be chronic or episodic. Because analgesics typically used to treat pain are not very effective in SCD, opioids, including morphine, are a primary treatment for managing pain in SCD but are associated with many serious side effects, including constipation, tolerance, addiction, and respiratory depression. Thus, there is a need for the development of novel treatments for pain in SCD. In this study, we used the Townes transgenic mouse model of SCD to investigate the antinociceptive efficacy of the bivalent ligand, MCC22, and compared its effectiveness with morphine. MCC22 consists of a mu-opioid receptor agonist and a chemokine receptor-5 (CCR5) antagonist that are linked through a 22 atom spacer. Our results show that intraperitoneal administration of MCC22 produced exceptionally potent dose-dependent antihyperalgesia as compared to morphine, dramatically decreased evoked responses of nociceptive dorsal horn neurons, and decreased expression of proinflammatory cytokines in the spinal cord. Moreover, tolerance did not develop to its analgesic effects after repeated administration. In view of the extraordinary potency of MCC22 without tolerance, MCC22 and similar compounds may vastly improve the management of pain associated with SCD. PMID- 29578948 TI - Hyperpolarization-activated cyclic nucleotide-gated channels contribute to spontaneous activity in L4 C-fiber nociceptors, but not Abeta-non-nociceptors, after axotomy of L5-spinal nerve in the rat in vivo. AB - Peripheral neuropathic pain associated with partial nerve injury is believed to be driven partly by aberrant spontaneous activity (SA) in both injured and uninjured dorsal root ganglion (DRG) neurons. The underlying ionic mechanisms are not fully understood, but hyperpolarization-activated cyclic nucleotide-gated (HCN) channels which underlie the excitatory Ih current have been implicated in SA generation in axotomized A-fiber neurons after L5-spinal nerve ligation/axotomy (SNL/SNA). Here, using a modified model of SNA (mSNA) which involves, in addition to L5-SNA, loose ligation of the L4-spinal nerve with neuroinflammation-inducing chromic gut, we examined whether HCN channels also contribute to SA in the adjacent L4-neurons. Intracellular recordings from L4-DRG neurons in control rats, and L4-DRG neurons in mSNA rats were made using in vivo voltage- and current-clamp techniques. Compared with control, L4 C-nociceptors and Abeta-low-threshold mechanoreceptors (LTMs) exhibited SA 7 days after mSNA. This was accompanied, in C-nociceptors, by a significant increase in Ih amplitude, the percentage of Ih-expressing neurons, and Ih activation rate. Hyperpolarization-activated cyclic nucleotide-gated channel blockade with ZD7288 (10 mg/kg, intravenously) suppressed SA in C-nociceptors, but not Abeta-LTMs, and caused in C-nociceptors, membrane hyperpolarization and a decrease in Ih activation rate. Furthermore, intraplantar injection of ZD7288 (100 MUM) was found to be as effective as gabapentin (positive control) in attenuating cold hypersensitivity in mSNA rats. These findings suggest that HCN channels contribute to nerve injury-induced SA in L4 C-nociceptors, but not Abeta-LTMs, and that ZD7288 exerts its analgesic effects by altering Ih activation properties and/or causing membrane hyperpolarization in L4 C-nociceptors. PMID- 29578947 TI - Chronic pain impairs cognitive flexibility and engages novel learning strategies in rats. AB - Cognitive flexibility, the ability to adapt behavior to changing outcomes, is critical to survival. The prefrontal cortex is a key site of cognitive control, and chronic pain is known to lead to significant morphological changes to this brain region. Nevertheless, the effects of chronic pain on cognitive flexibility and learning remain uncertain. We used an instrumental paradigm to assess adaptive learning in an experimental model of chronic pain induced by tight ligation of the spinal nerves L5/6 (spinal nerve ligation model). Naive, sham operated, and spinal nerve ligation (SNL) rats were trained to perform fixed ratio, variable-ratio, and contingency-shift behaviors for food reward. Although all groups learned an initial lever-reward contingency, learning was slower in SNL animals in a subsequent choice task that reversed reinforcement contingencies. Temporal analysis of lever-press responses across sessions indicated no apparent deficits in memory consolidation or retrieval. However, analysis of learning within sessions revealed that the lever presses of SNL animals occurred in bursts, followed by delays. Unexpectedly, the degree of bursting correlated positively with learning. Under a variable-ratio probabilistic task, SNL rats chose a less profitable behavioral strategy compared with naive and sham-operated animals. After extinction of behavior for learned preferences, SNL animals reverted to their initially preferred (ie, less profitable) behavioral choice. Our data suggest that in the face of uncertainty, chronic pain drives a preference for familiar associations, consistent with reduced cognitive flexibility. The observed burst-like responding may represent a novel learning strategy in animals with chronic pain. PMID- 29578949 TI - How condition-specific do measures of pain intensity need to be?

AB - OBJECTIVES: To validate and compare performance of an International Classification of Diseases, tenth revision (ICD-10) version of a combined comorbidity index merging conditions of Charlson and Elixhauser measures against individual measures in the prediction of 30-day mortality. To select a weight derivation method providing optimal performance across ICD-9 and ICD-10 coding systems. RESEARCH DESIGN: Using 2 adult population-based cohorts of patients with hospital admissions in ICD-9 (2005, n=337,367) and ICD-10 (2011, n=348,820), we validated a combined comorbidity index by predicting 30-day mortality with logistic regression. To appreciate performance of the Combined index and both individual measures, factors impacting indices performance such as population characteristics and weight derivation methods were accounted for. We applied 3 scoring methods (Van Walraven, Schneeweiss, and Charlson) and determined which provides best predictive values. RESULTS: Combined index [c-statistics: 0.853 (95% confidence interval: CI, 0.848-0.856)] performed better than original Charlson [0.841 (95% CI, 0.835-0.844)] or Elixhauser [0.841 (95% CI, 0.837 0.844)] measures on ICD-10 cohort. All weight derivation methods provided close high discrimination results for the Combined index (Van Walraven: 0.852, Schneeweiss: 0.851, Charlson: 0.849). Results were consistent across both coding systems. CONCLUSIONS: The Combined index remains valid with both ICD-9 and ICD-10 coding systems and the 3 weight derivation methods evaluated provided consistent high performance across those coding systems. PMID- 29578952 TI - Failure-to-Rescue After Acute Myocardial Infarction. AB - BACKGROUND: Failure-to-rescue (FTR), originally developed to study quality of care in surgery, measures an institution's ability to prevent death after a patient becomes complicated. OBJECTIVES: Develop an FTR metric modified to analyze acute myocardial infarction (AMI) outcomes. RESEARCH DESIGN: Split-sample design: a random 20% of hospitals to develop FTR definitions, a second 20% to validate test characteristics, and an out-of-sample 60% to validate results. SUBJECTS: Older Medicare beneficiaries admitted to short-term acute-care hospitals for AMI between 2009 and 2011. MEASURES: Thirty-day mortality and FTR rates, and in-hospital complication rates. RESULTS: The 60% out-of-sample validation included 234,277 patients across 1142 hospitals that admitted at least 50 patients over 2.5 years. In total, 72.1% of patients were defined as Medically Complicated (complex on admission or subsequently developed a complication or died without a recorded complication) of whom 19.3% died. Spearman r between hospital risk-adjusted 30-day mortality and FTR was 0.89 (P<0.0001); Mortality versus Complication=-0.01 (P=0.6198); FTR versus Complication=-0.10 (P=0.0011). Major teaching hospitals displayed 19% lower odds of FTR versus non-teaching hospitals (odds ratio=0.81, P<0.0001), while hospitals as a group defined by teaching hospital status, comprehensive cardiac technology, and having good nursing mix and staffing, displayed a 33% lower odds of FTR (odds ratio=0.67, P<0.0001) versus hospitals without any of these characteristics. CONCLUSIONS: A modified FTR metric can be created that has many of the advantageous properties of surgical FTR and can aid in studying the quality of care of AMI admissions. PMID- 29578953 TI - Care Coordination and Multispecialty Teams in the Care of Colorectal Cancer Patients. AB - OBJECTIVES: To estimate the association between provider and team experience and adherence to guidelines, survival, and utilization among colorectal cancer patients in North Carolina. SUBJECTS: The analysis cohort included 7295 patients diagnosed with incident stage II/III colorectal cancer between 2004 and 2013 who received surgery. METHODS: Primary outcomes included adherence to guidelines: consultation with a medical oncologist (stage III), receipt of adjuvant chemotherapy (stage III), and receipt of surveillance colonoscopy posttreatment. Secondary outcomes included 5-year overall survival, number of surveillance radiology studies, any unplanned hospitalization, and any emergency department visit. The primary predictors were measures of provider volume and patient sharing across surgeons and medical oncologists. Regression analyses adjusted for patient and provider characteristics. RESULTS: Patients whose surgeons shared >40% of their colorectal cancer patients in the previous year with a medical oncologist were (1) more likely to have had a consultation with a medical oncologist [marginal effect (ME)=13.3 percentage points, P-value<0.001], (2) less likely to receive a surveillance colonoscopy within 12 months (ME=3.5 percentage points, P-value=0.049), and (3) received more radiology studies (ME=0.254 studies, P-value=0.029). Patients whose surgeon and medical oncologist shared >20% of their colorectal cancer patients with each other in the previous year had a higher likelihood of receiving adjuvant chemotherapy (ME=11.5 percentage points, P-value<0.001) and surveillance colonoscopy within 12 months (ME=6.7 percentage points, P-value=0.030) and within 18 months (ME=6.2 percentage points, P-value=0.054). CONCLUSIONS: Our study shows that team experience is associated with patients' quality of care, survival, and utilization. PMID- 29578954 TI - Health Care Costs and Utilization of Dabigatran Compared With Warfarin for Secondary Stroke Prevention in Patients With Nonvalvular Atrial Fibrillation: A Retrospective Population Study. AB - BACKGROUND: It remains unclear whether the use of new oral anticoagulants, compared with warfarin, is economically beneficial in Asian countries. OBJECTIVE: The objective of this study is to compare the health care costs and utilization between dabigatran and warfarin in a real-world nonvalvular atrial fibrillation (NVAF) population. RESEARCH DESIGN: Data were obtained from the Taiwan National Health Insurance Database, and patients with an NVAF diagnosis between June 1, 2012, and May 31, 2014, were identified using the International Classification of Diseases, Ninth Revision code of 427.31. The patients in the dabigatran cohort were matched 1:2 to those in the warfarin cohort by sex, age, residential region, and a propensity score that incorporated a major bleeding history, CHADS2 score, and Charlson Comorbidity Index. The all-cause health care utilization and associated costs of the 2 treatment groups were compared at 3 and 12 months. RESULTS: A total of 1149 patients taking dabigatran were identified and matched with 2298 warfarin users. During the 3-month observation period, the likelihood of having at least 1 hospitalization among dabigatran users was significantly lower than that of warfarin users (odds ratio=0.78; P=0.001). Patients in the dabigatran group incurred lower mean emergency department costs ($2383.1 vs. $3033.6), mean ischemic stroke-related hospitalization costs ($8869.5 vs. $13,990.5), and mean all-cause hospitalization costs ($32,402.2 vs. $50,669.9) at 3 months. However, both the mean and median outpatient costs of warfarin users were consistently lower than those of dabigatran users ($17,161.2 vs. $24,931.4 and $10,509.0 vs. $20,671.5, respectively). Similar trends were observed at 12 months, except that the 2 groups had comparable total health care costs. CONCLUSIONS: The use of dabigatran is associated with lower emergency department and all-cause hospitalization costs but greater outpatient costs in a real-world, NVAF patient population compared with warfarin.

AB - BACKGROUND: There is interest in assessing health care utilization and expenditures among new Medicaid enrollees after the 2014 Medicaid expansion. Recent studies have not differentiated between newly enrolled individuals and those returning after coverage gaps. OBJECTIVES: To assess health care expenditures among Medicaid enrollees in the 24 months after Oregon's 2014 Medicaid expansions and examine whether expenditure patterns were different among the newly, returning, and continuously insured (CI). RESEARCH DESIGN: Retrospective cohort study using inverse-propensity weights to adjust for differences between groups. SUBJECTS: Oregon adult Medicaid beneficiaries insured continuously from 2014 to 2015 who were either newly, returning, or CI. MEASURES: Monthly expenditures for inpatient care, prescription drugs, total outpatient care, and subdivisions of outpatient care: emergency department, dental, mental and behavioral health, primary care, and specialist care. RESULTS: After initial increases, newly and returning insured (RI) outpatient expenditures dropped below CI. Expenditures for emergency department and dental services among the RI remained higher than among the newly insured. Newly insured mental and behavioral health, primary care, and specialist expenditures plateaued higher than RI. Prescription drug expenditures increased over time for all groups, with CI highest and RI lowest. All groups had similar inpatient expenditures over 24 months post-Medicaid expansion. CONCLUSIONS: Our findings reveal that outpatient expenditures for new nonpregnant, non-dual-eligible Oregon Medicaid recipients stabilized over time after meeting pent-up demand, and prior insurance history affected the mix of services that individuals received. Policy evaluations should consider expenditures over at least 24 months and should account for enrollees' prior insurance histories.

PMID- 29578964 TI - Comparison between invasive and noninvasive techniques of evaluation of microvascular structural alterations. AB - BACKGROUND: The evaluation of the morphological characteristics of small resistance arteries in humans is challenging. The gold standard method is generally considered to be the measurement by wire or pressure micromyography of the media-to-lumen ratio of subcutaneous small vessels obtained by local biopsies. However, noninvasive techniques for the evaluation of retinal arterioles were recently proposed; in particular, two approaches, scanning laser Doppler flowmetry (SLDF) and adaptive optics, seem to provide useful information; both of them provide an estimation of the wall-to-lumen ratio (WLR) of retinal arterioles. Moreover, a noninvasive measurement of basal and total capillary density may be obtained by videomicroscopy/capillaroscopy. No direct comparison of these three noninvasive techniques in the same population was previously performed; in particular, adaptive optics was never validated against micromyography. METHODS: In the current study, we enrolled 41 controls and patients: 12 normotensive lean controls, 12 essential hypertensive lean patients, nine normotensive obese patients and eight hypertensive obese patients undergoing elective surgery. All patients underwent a biopsy of subcutaneous fat during surgery. Subcutaneous small resistance artery structure was assessed by wire micromyography and the media-to-lumen ratio was calculated. WLR of retinal arterioles was obtained by SLDF and adaptive optics. Functional (basal) and structural (total) microvascular density was evaluated by capillaroscopy before and after venous congestion. RESULTS AND CONCLUSION: Our data suggest that adaptive optics has a substantial advantage over SLDF in terms of evaluation of microvascular morphology, as WLR measured with adaptive optics is more closely correlated with the M/L of subcutaneous small arteries (r = 0.84, P < 0.001 vs. r = 0.52, P < 0.05, slopes of the relations: P < 0.01 adaptive optics vs. SLDF). In addition, the reproducibility of the evaluation of the WLR with adaptive optics is far better, as compared with SLDF, as intraobserver and interobserver variation coefficients are clearly smaller. This may be important in terms of clinical evaluation of microvascular morphology in a clinical setting, as micromyography has substantial limitations in its clinical application due to the local invasiveness of the procedure.

PMID- 29578983 TI - ACOG Committee Opinion No. 732 Summary: Influenza Vaccination During Pregnancy. AB - Influenza vaccination is an essential element of prepregnancy, prenatal, and postpartum care because influenza can result in serious illness, including a higher chance of progressing to pneumonia, when it occurs during the antepartum or postpartum period. In addition to hospitalization, pregnant women with influenza are at increased risk of intensive care unit admission and adverse perinatal and neonatal outcomes. The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices and the American College of Obstetricians and Gynecologists recommend that all adults receive an annual influenza vaccine and that women who are or will be pregnant during influenza season receive an inactivated influenza vaccine as soon as it is available. In the United States, the influenza season typically occurs from October to May. Ideally, an influenza vaccination should be given before the end of October, but vaccination throughout the influenza season is encouraged to ensure protection during the period of circulation. Any of the licensed, recommended, age appropriate, inactivated influenza vaccines can be given safely during any trimester. Therefore, it is critically important that obstetrician-gynecologists and other obstetric care providers recommend and advocate for the influenza vaccine. Obstetrician-gynecologists are encouraged to stock and administer the influenza vaccine to their pregnant patients in their offices, and should get the influenza vaccine themselves every season. If the influenza vaccine cannot be offered in a practice, obstetrician-gynecologists and obstetric care providers should refer patients to another health care provider, pharmacy, or community vaccination center. This updated Committee Opinion includes more recent data on the safety and efficacy of influenza vaccination during pregnancy and recommendations for treatment and postexposure chemoprophylaxis. PMID- 29578984 TI - ACOG Committee Opinion No. 733 Summary: Employment Considerations During Pregnancy and the Postpartum Period. AB - In the United States, it is common for women, including mothers and pregnant women, to work outside the home. Working during pregnancy is generally safe. For those in high-risk occupations or with medically complicated pregnancies, work accommodations often can allow for continued safe employment. The major employment issues concerning pregnant women include pregnancy-related discrimination, work accommodations that allow continued employment, job protected leave, and wage replacement while on leave. Workplace discrimination related to being pregnant and pregnancy-related harassment, including discrimination in the hiring process, is prohibited by federal and state law. There is no federal law guaranteeing comprehensive accommodations for pregnant and postpartum workers. Current federal and state laws provide protection for some pregnant women, but not others, because of eligibility requirements and state-by-state differences. By writing appropriate notes to employers, obstetrician-gynecologists and other obstetric care providers can be instrumental in obtaining accommodations for their patients who are able to continue working. Accommodations that allow a woman to keep working are the most reliable way to guarantee pay, benefits, and job protection. Obstetrician-gynecologists and other obstetric care providers also can assist pregnant women and their partners by providing them with information and resources that might help them better understand their employment rights. However, in cases for which potential job discrimination has occurred, accommodations are denied, extended medical leave is necessary, or when other complex employment questions arise, legal assistance should be obtained.

PMID- 29578987 TI - Beyond the real world: attention debates in auditory mismatch negativity. AB - The aim of this study was to address the potential for the auditory mismatch negativity (aMMN) to be used in applied event-related potential (ERP) studies by determining whether the aMMN would be an attention-dependent ERP component and could be differently modulated across visual tasks or virtual reality (VR) stimuli with different visual properties and visual complexity levels. A total of 80 participants, aged 19-36 years, were assigned to either a reading-task (21 men and 19 women) or a VR-task (22 men and 18 women) group. Two visual-task groups of healthy young adults were matched in age, sex, and handedness. All participants were instructed to focus only on the given visual tasks and ignore auditory change detection. While participants in the reading-task group read text slides, those in the VR-task group viewed three 360 degrees VR videos in a random order and rated how visually complex the given virtual environment was immediately after each VR video ended. Inconsistent with the finding of a partial significant difference in perceived visual complexity in terms of brightness of virtual environments, both visual properties of distance and brightness showed no significant differences in the modulation of aMMN amplitudes. A further analysis was carried out to compare elicited aMMN amplitudes of a typical MMN task and an applied VR task. No significant difference in the aMMN amplitudes was found across the two groups who completed visual tasks with different visual-task demands. In conclusion, the aMMN is a reliable ERP marker of preattentive cognitive processing for auditory deviance detection. PMID- 29578988 TI - Diversity.

PMID- 29578990 TI - Effects of Postural Management on Hip Migration in Children With Cerebral Palsy: A Systematic Review. AB - PURPOSE: To review the existing literature on the effects of postural management on hip migration in children with cerebral palsy. METHODS: A systematic literature search was performed using 5 databases. Quality of articles was assessed and study designs were appraised according to the American Academy of Cerebral Palsy and Developmental Medicine Systematic Review Method. RESULTS: Eight of 655 identified studies were included, reporting postural management in children with cerebral palsy. Seven of 8 studies reported positive effects on hip migration after postural management interventions. However, level of evidence and quality of the articles were low. CONCLUSION: The evidence for postural management to prevent or reduce hip migration in children with cerebral palsy is limited by the lack of high-quality studies. Strong recommendations for clinical practice are not possible. Future high-quality research is crucial to improve our understanding of the effects of postural management to prevent hip migration in children with cerebral palsy.

AB - PURPOSE: To determine the changes in the prefrontal cortical (PFC) activation following hand-arm bimanual intensive therapy (HABIT) in children with hemiplegic cerebral palsy (HCP). METHODS: Nine children with HCP and 15 children who were developing typically participated in the study. Children with HCP received 50 hours of HABIT. We assessed pre- and post-HABIT PFC activation using functional near-infrared spectroscopy neuroimaging. Bimanual coordination and motor task performance were assessed using the Assisting Hand Assessment (AHA), the average number of shapes matched, the shape matching errors, the reaction time, the 9 hole peg test, and the box and blocks test. RESULTS: The PFC activation decreased following HABIT and became similar to what was seen in the children who were developing typically. Post-HABIT PFC activation improvements paralleled with the improvements seen in the AHA and the behavioral outcomes. CONCLUSION: HABIT potentially improves the PFC's involvement in the action planning of the upper extremity movements in children with HCP.

AB - PURPOSE: To evaluate the gross motor development of 5-year-olds using the Peabody Developmental Motor Scales, 2nd Edition (PDMS-2), test after initial nonoperative management of clubfoot as infants. METHODS: The PDMS-2 Stationary, Locomotion, and Object Manipulation subtests were assessed on 128 children with idiopathic clubfeet at the age of 5 years. Children were categorized by their initial clubfoot severity as greater than 13, unilateral or bilateral involvement, and required surgery. RESULTS: Children with treated clubfeet had average gross motor scores (99 Gross Motor Quotient) compared with age-matched normative scores. Children with more severe clubfeet required surgery significantly more than children with less severe scores (P < .01). Peabody scores were not significantly different according to initial clubfoot severity, unilateral versus bilateral involvement, and surgical versus nonsurgical outcomes. CONCLUSIONS: Clubfoot does not significantly impair gross motor development in 5-year-olds. PMID- 29578995 TI - Commentary on "Clubfoot Does Not Impair Gross Motor Development in 5-Year-Olds". PMID- 29578996 TI - Role of Pediatric Physical Therapists in Promoting Sports Participation in Developmental Coordination Disorder. AB - PURPOSE: To explore the role of pediatric physical therapists (PPT) in promoting sports participation in children with developmental coordination disorder (DCD) and identify associated barriers and facilitators. METHODS: Questionnaires were provided to 243 PPTs. Qualitative, semistructured, in-depth interviews were administered with the PPTs, children with DCD, and parents. RESULTS: Approximately 67% of questionnaires were returned. Approximately 46% of PPTs were active in guiding children with DCD to sports clubs. This guidance was facilitated by knowledge of local sports, clubs that include children with DCD, and contact persons. Barriers to sports participation were the motor impairment or coincident disorder, insufficient participants to compose a team, and lack of guidance on how to include children with DCD. CONCLUSIONS: PPTs currently guide children with DCD to sports clubs, but this guidance may be improved by connecting them to special exercise programs and mainstream sports clubs and examining children's experiences during sports.

AB - PURPOSE: The purpose of this study was to determine effectiveness of a midliner positioning system (MPS, Tortle Midliner) for preventing dolichocephaly. METHODS: This was a nonrandomized, prospective study of 30 premature infants (study cohort, SC) using an MPS compared with a retrospective study cohort (RSC) of 65 infants who received standard of care intervention. RESULTS: RSC baseline cranial index (CI) of 80% and final CI of 77% significantly decreased over an average 5.5 weeks (P < .0001). The SC baseline CI and the final CI were both 79% over an average 5.7 weeks, indicating no significant difference between CI measures (P = .6). Gestational age, birth weight, reflux, time on continuous positive airway pressure, and time in a supine position were not associated with dolichocephaly. CONCLUSIONS: The SC developed less cranial molding (ie, had greater CI), compared with the RSC. A larger randomized study is needed to recommend routine use of MPS for prevention and/or treatment of cranial molding in premature infants.

PMID- 29579002 TI - Descriptive Report of the Impact of Fatigue and Current Management Strategies in Cerebral Palsy. AB - PURPOSE: To describe the effect of fatigue and self-management practices for adolescents and young adults with cerebral palsy. METHODS: A survey of 124 people with cerebral palsy with the Fatigue Impact and Severity Self-Assessment. RESULTS: Participants in Gross Motor Function Classification System (GMFCS) level I experienced little effect of fatigue, with high proportions of this group disagreeing to statements about fatigue impacting their general activities, mobility, and social activities. Participants in GMFCS levels II to V reported effect of fatigue on activities. Differences between groups were evident in questions related to fatigue interference with length of time for physical activity and with motivations to participate in social activities. All other items related to management of fatigue were not significantly different between groups. CONCLUSIONS: Fatigue effect is greater for participants with more functional limitations. The lack of significant differences between groups, on the Management and Activity Modification subscale, indicates more research is needed regarding strategies for fatigue management.

PMID- 29579004 TI - Head Control Changes After Headpod Use in Children With Poor Head Control: A Feasibility Study. AB - PURPOSE: To determine the feasibility of Headpod use to improve head control in children with cerebral palsy classified as Gross Motor Function Classification System level V. METHODS: Children (3-11 years) with poor head control were video recorded before and after 3 and 6 months of Headpod use. Head control without Headpod was measured by active time children could hold head upright and number of head bobs in 5 minutes. RESULTS: Fourteen children enrolled with 43% attrition rate. While average active time increased, average head bobs decreased and there were significant improvements in active time, but not head bobs. Active times were higher at 6 months compared with 3 months and baseline. Surveyed parents reported that the changes were apparent, supporting the large quantitative treatment effect. CONCLUSIONS: Six months of Headpod use, 45 minutes per day, appears to be feasible, has a large effect on active head control, and merits a larger randomized controlled trial. PMID- 29579005 TI - A Pediatric Service-Learning Program in Physical Therapy Education. AB - PURPOSE: The purpose of this report was to describe a pediatric service-learning program in entry-level physical therapy (PT) education in Taiwan. KEY POINTS: To meet the needs of the local community and provide preclinical service-learning experience to PT students with people with physical disability, a service learning program of a 2-day camp for children with cerebral palsy (CP) was developed in 2012. To date, 356 entry-level PT students have participated in this program, serving 286 children and their families. Important professional attributes, identified by the World Confederation for Physical Therapy guideline, such as altruism, compassion and caring, cultural competence, personal and professional development, professional duty, social responsibility and advocacy, and teamwork, were in the reflective reports of some of the PT students. CONCLUSIONS: The experiences provided by this pediatric PT service-learning program appear to have the potential to foster the development of professional attributes in entry-level PT students. PMID- 29579006 TI - Epidemiology of Cerebral Palsy in Northeastern Switzerland. AB - PURPOSE: Cerebral palsy (CP) is the most common motor disability of childhood. Less is known about its prevalence and associated factors in Switzerland, so we aimed to fill this knowledge gap in one Swiss canton, evaluating the feasibility to build up a CP registry. METHODS: A retrospective review of medical records was undertaken. Children born during 1995 and 2009 in the canton of Saint Gallen diagnosed with CP were eligible for inclusion. RESULTS: A total of 140 patients formed the study cohort. The prevalence of CP was 0.19%, with 85% of children affected by spastic CP. CONCLUSIONS: The results of the present study were comparable with data of the Surveillance of Cerebral Palsy in Europe network. Moreover, this pilot study demonstrated the feasibility and usefulness of creating a registry of children affected by CP. PMID- 29579008 TI - Functional Mobility Improved After Intensive Progressive Resistance Exercise in an Adolescent With Spina Bifida. AB - PURPOSE: To describe the use and effectiveness of a novel intensive progressive resistance exercise (PRE) approach to address the functional goals of a 14-year old adolescent with a myelomeningocele. SUMMARY OF KEY POINTS: The child had lower extremity weakness, knee and hip flexion contractures, impaired somatosensation, and cardiopulmonary deconditioning, affecting gait mechanics and functional ambulation. An 8-week intensive PRE-based intervention was designed to improve walking in the home by targeting both power-generating and stabilizing lower extremity musculature. Secondary intervention focused on cardiopulmonary endurance training. CONCLUSIONS: The child demonstrated improvements in gait speed, walking endurance, and functional lower extremity strength. Knee contracture was moderately responsive to sustained stretching and positioning. WHAT THIS CASE ADDS TO EVIDENCE-BASED PRACTICE: This intensive PRE training approach had been effective for improving function among youth with cerebral palsy, and to our knowledge it had not yet been applied to youth with other neurological conditions. PMID- 29579009 TI - Targeted Training in Managing Children With Poor Trunk Control: 4 Case Reports. AB - PURPOSE: This study investigated whether targeted training was feasible with young children younger than 2 years with poor trunk control due to cerebral palsy or developmental delay without using specialized equipment and the overall change in trunk control and functional ability, with the addition of targeted training to standard care physical therapy. SUMMARY OF KEY POINTS: Four children younger than 24 months with motor disorders were recruited. No difficulty was identified in using targeted training with this group. Within 3 months of commencing intervention, the 4 children had increased trunk control and functional abilities including independent sitting and bilateral hand use in play. CONCLUSIONS AND RECOMMENDATIONS FOR CLINICAL PRACTICE: This form of targeted training was feasible for young children with motor disorders and augmented standard care therapy in enhancing both trunk control and motor skills. Targeted training should be further investigated as a potentially effective treatment. PMID- 29579011 TI - Histologic and Outcome Study Supports Reclassifying Appendiceal Goblet Cell Carcinoids as Goblet Cell Adenocarcinomas, and Grading and Staging Similarly to Colonic Adenocarcinomas. AB - Goblet cell carcinoid tumors are amphicrine tumors whose biological behavior ranges from indolent to highly aggressive, depending on tumor grade. Current grading systems for these tumors are based on identifying an adenocarcinoma arising in the setting of a goblet cell carcinoid tumor, which distinguishes this tumor from other gastrointestinal tract adenocarcinomas. Because goblet cell tumors are predominantly tumors of mucin secreting cells, we propose that they be classified as goblet cell adenocarcinomas, and graded using a methodology that has parallels in colorectal adenocarcinoma grading. We graded a large series of goblet cell adenocarcinomas by assessing the proportion of the tumor that demonstrates tubular or clustered growth. Histologic grade correlated with overall survival independent of stage, with median overall survival of 204, 86, and 29 months for low-grade, intermediate-grade, and high-grade goblet cell adenocarcinomas, respectively. Tumor stage also correlated with overall survival. We also graded the tumors according to previously proposed grading systems, and found that these systems are valid, in that they segregate patients according to prognosis. PMID- 29579010 TI - Intraoperative Consultation and Macroscopic Handling: The International Society of Urological Pathology (ISUP) Testicular Cancer Consultation Conference Recommendations. AB - The International Society of Urological Pathology held a conference on issues in testicular and penile pathology in Boston in March 2015, which included a presentation by the testis macroscopic features working group. The presentation focused on current published guidance for macroscopic handling of testicular tumors and retroperitoneal lymph node dissections with a summary of results from an online survey of members preceding the conference. The survey results were used to initiate discussions, but decisions on practice were made by expert consensus rather than voting. The importance of comprehensive assessment at the time of gross dissection with confirmation of findings by microscopic assessment was underscored. For example, the anatomic landmarks denoting the distinction of hilar soft tissue invasion (pT2) from spermatic cord invasion (pT3 category) can only be determined by careful macroscopic assessment in many cases. Other recommendations were to routinely sample epididymis, rete testis, hilar soft tissue, and tunica vaginalis in order to confirm macroscopic invasion of these structures or if not macroscopically evident, to exclude subtle microscopic invasion. Tumors 2 cm or less in greatest dimension should be completely embedded. If the tumor is >2 cm in greatest dimension, 10 blocks or a minimum of 1 to 2 additional blocks per centimeter should be taken (whichever is greater). PMID- 29579012 TI - The Influence of Concordant Complex Posture and Loading Rate on Motion Segment Failure: A Mechanical and Microstructural Investigation. AB - STUDY DESIGN: Microstructural investigation of compression-induced herniation of a lumbar disc held in a concordant complex posture. OBJECTIVE: To explore the significance of loading rate in a highly asymmetric concordant posture, comparing the mechanisms of failure to an earlier study using a nonconcordant complex posture. SUMMARY OF BACKGROUND DATA: A recent study with a nonconcordant complex posture (turning in the opposite direction to that which the load is applied) demonstrated the vulnerability of the disc to loading that is borne by one set of oblique-counter oblique fiber sets in the alternating lamellae of the annulus, and aggravated by an elevated loading rate. Given the strain rate-dependent properties of the disc it might be expected that the outcome differs if the posture is reversed. METHODS: Forty-one motion segments from ovine 16 spines were split into two cohorts; adopting the previously employed low rate (40 mm/min) and surprise rate (400 mm/min) of loading. Both groups of damaged discs were then analyzed microstructurally. RESULTS: With the lower rate loading the concordant posture significantly reduced the load required to cause disc failure than earlier described for nonconcordant posture (6.9 vs. 8.4 kN), with more direct tears and alternate lamella damage extending to the anterior disc. Contrary to this result, with a surprise rate, the load at failure was significantly increased with the concordant posture (8.08 vs. 6.96 kN), although remaining significantly less than that from a simple flexed posture (9.6 kN). Analysis of the damage modes and postures suggest facet engagement plays a significant role. CONCLUSION: This study confirms that adding shear to the posture lowers the load at failure, and causes alternate lamella rupture. Load at failure in a complex posture is not determined by loading rate alone. Rather, the strain rate dependent properties of the disc influence which elements of the system are brought into play. LEVEL OF EVIDENCE: N/A. PMID- 29579013 TI - The Impact of Comorbid Mental Health Disorders on Complications Following Cervical Spine Surgery With Minimum 2-Year Surveillance. AB - STUDY DESIGN: Retrospective analysis. OBJECTIVE: To improve understanding of the impact of comorbid mental health disorders (MHDs) on long-term outcomes following cervical spinal fusion in cervical radiculopathy (CR) or cervical myelopathy (CM) patients. SUMMARY OF BACKGROUND DATA: Subsets of patients with CR and CM have MHDs, and their impact on surgical complications is poorly understood. METHODS: Patients admitted from 2009 to 2013 with CR or CM diagnoses who underwent cervical surgery with minimum 2-year surveillance were retrospectively reviewed using New York State's Statewide Planning and Research Cooperative System. Patients with a comorbid MHD were compared against those without (no-MHD). Univariate analysis compared demographics, complications, readmissions, and revisions between MHD and no-MHD cohorts. Multivariate binary logistic regression models identified independent predictors of outcomes (covariates: age, sex, Charlson/Deyo score, and surgical approach). RESULTS: A total of 20,342 patients (MHD: n = 4819; no-MHD: n = 15,523) were included. MHDs identified: depressive (57.8%), anxiety (28.1%), sleep (25.2%), and stress (2.9%). CR patients had greater prevalence of comorbid MHD than CM patients (P = 0.015). Two years postoperatively, all patients with MHD had significantly higher rates of complications (specifically: device-related, infection), readmission for any indication, and revision surgery (all P < 0.05); regression modeling corroborated these findings and revealed combined surgical approach as the strongest predictor for any complication (CR, odds ratio [OR]: 3.945, P < 0.001; CM, OR: 2.828, P < 0.001) and MHD as the strongest predictor for future revision (CR, OR: 1.269, P = 0.001; CM, OR: 1.248, P = 0.008) in both CR and CM cohorts. CONCLUSION: Nearly 25% of patients admitted for CR and CM carried comorbid MHD and experienced greater rates of any complication, readmission, or revision, at minimum, 2 years after cervical spine surgery. Results must be confirmed with retrospective studies utilizing larger national databases and with prospective cohort studies. Patient counseling and psychological screening/support are recommended to complement surgical treatment. LEVEL OF EVIDENCE: 3. PMID- 29579014 TI - A Physical Test to Estimate Suitable Workloads for an Exercise Program in Breast Cancer Survivors. AB - Epidemiologic studies suggest that patients with breast cancer who gain weight after diagnosis have a higher risk of recurrence and death. Regular physical exercise can help minimize post-diagnosis weight gain. The objective of the study was to assess the effectiveness of a physical test for individualizing the workloads used during a fitness program.To continuously individualize the intensity of the training, a test was designed and integrated into the sessions. The test consisted in monitoring heart rate and workload during two bouts of cycling at moderate intensity. The workload parameters recorded during the tests were later used as reference values to plan the intensity of the next inperson training sessions.The five tests carried out during the twelve weeks of the intervention showed significant differences in intensity (F=3.034, p=0.047). Compared to the first evaluation, the intensities measured during the third, fourth and fifth tests presented increases of 9.9% (p=0.02), 13.2% (p=0.019) and 17.5% (p=0.002) respectively. A significant increase in workload with respect to body weight was observed in the physical assessment performed after the program (t= 13.2, p=0.0001). The peak oxygen consumption with respect to body weight (peak VO2) achieved by the participants during the assessment at the end of the program had also increased (t= 9.72, P= 0.0001).The intensity test, introduced in the training sessions along with the physical exercise program, was an easy-to use, practical tool for monitoring intensity. It allows an adjustment of the workload over the program period that respects the individual progression of each patient. PMID- 29579015 TI - The aVOR App Increases Medical Students' Competence in Treating Benign Paroxysmal Positional Vertigo (BPPV). AB - HYPOTHESIS: Implementation of the "aVOR app" into teaching courses at medical school enhances students' satisfaction with the course and increases their competence in treating benign paroxysmal positional vertigo (BPPV). BACKGROUND: BPPV is often underdiagnosed and left untreated. One problem in teaching the management of BPPV to health care professionals is the lack of simulation-based training tools. The aVOR app (aVOR = angular vestibulo-ocular reflex) works as a bionic labyrinth that simulates the activation of the semicircular canals by rotational acceleration and the resulting vestibular evoked eye movements. METHODS: In this prospective, randomized, controlled study, medical students at a university hospital were randomly assigned to two kinds of small instructional groups. Students of the control group (n = 67) practiced diagnostic and therapeutic maneuvers for BPPV on each other, while the participants of the study group (n = 46) used the aVOR app as a virtual patient in addition. At the end of the term, students were asked to arrange the steps of the canalith repositioning procedure in the correct order in a written test. RESULTS: Quality of the teaching media was rated significantly better in the aVOR group (two-sided Mann Whitney test: P < 0.00001). Significantly more students of the aVOR group than the control group arranged the steps of the canalith repositioning procedure correctly in the final exam (56.3% versus 25.9%, Fisher's exact test: P = 0.006). CONCLUSION: Implementation of the aVOR app as a virtual patient into small instructional courses is well adopted by medical students and increases their competence in treating BPPV.

PMID- 29579018 TI - Using Black Bone Magnetic Resonance Imaging in Craniofacial Virtual Surgical Planning: A Comparative Cadaver Study. AB - BACKGROUND: The use of magnetic resonance imaging (MRI) for virtual surgical planning has not yet been described. In the United States, over 600,000 computed tomographic (CT) scans are performed annually on children, who are at higher risk than adults of developing cancer caused by ionizing radiation. The aim of this study was to demonstrate whether three-dimensionally-printed craniofacial surgical guides created from "black bone" MRI are comparable in accuracy to those created from CT scans. METHODS: A mock craniosynostosis surgery translocating four calvarial segments was virtually planned and performed in 10 cadavers. For five specimens, planning was performed and three-dimensionally-printed guides were created using black bone MRI scans. Five specimens underwent standard planning using CT scans. Reconstructed skulls underwent CT scans and three dimensional reconstruction. Accuracy was compared to that of virtually planned surgeries. RESULTS: The preoperative black bone MRI scan had an average deviation from the preoperative CT scan of 1.37 mm. There was no statistically significant difference in the fit accuracy of MRI versus CT-created guides. Average deviation of postoperative anatomy from preoperative plan was within 1.5 mm for guides created from either scanning modality, with no statistically significant difference in accuracy between the two methods. Planned versus postoperative skull volume was not statistically significantly different when MRI versus CT was used. CONCLUSIONS: This study demonstrates that virtual surgical planning and three-dimensional craniofacial surgical guide creation can be performed using black bone MRI with accuracy comparable to that of CT. This could dramatically reduce radiation exposure of craniofacial reconstruction patients. PMID- 29579019 TI - Long-Term Outcomes of Smile Reconstruction in Mobius Syndrome. AB - BACKGROUND: Gracilis muscle transplant is the standard of care for smile reconstruction in children with Mobius syndrome. The authors describe the long term clinical efficacy, durability, and psychosocial impact of this approach at a mean follow-up of 20 years. METHODS: Patients with Mobius syndrome who underwent gracilis muscle transfer between 1985 and 2005 were included in the study. The authors assessed midfacial movements using photographs and Scaled Measurement of Improvement in Lip Excursion measure, administered the patient-reported Facial Clinimetric Evaluation Scale, and used semistructured interviews. RESULTS: The mean age at surgery was 13.2 +/-10.6 years and the mean follow-up was 20.4 +/- 4.4 years postoperatively. Twenty-two gracilis muscle transplants were performed, all innervated by the motor nerve to the masseter. Photographic analysis using Scaled Measurement of Improvement in Lip Excursion software demonstrated that movement of the muscle was unchanged 20 years after surgery. Smile symmetry was stable long term. The overall mean Facial Clinimetric Evaluation score of the cohort was 62.3 +/- 12.0. Facial comfort (86.4 +/- 21.2) and social function (69.9 +/- 18.5) subdomains were the highest. Although the facial movement subdomain score was 35.6 +/- 12.4, the score related to smiling alone was 84.1 +/ 20.2, indicating satisfaction with the midfacial reconstruction. Interview responses indicated high satisfaction with surgery; fulfilled expectations of social acceptance; improved communication; enhanced self-confidence; and a sense of increased facial symmetry, spontaneity, and smile excursion. CONCLUSION: Segmental gracilis muscle transplantation provides long-lasting, durable improvements in objective and patient-reported measures of facial function. PMID- 29579020 TI - Quality of Life in Adults with Nonsyndromic Craniosynostosis. AB - BACKGROUND: Although studies have analyzed quality of life in children with nonsyndromic craniosynostosis, to date nobody has investigated long-term quality of life in adults with nonsyndromic craniosynostosis. The purpose of this study was to compare quality of life in adult nonsyndromic craniosynostosis patients with a cohort of unaffected controls. METHODS: The authors queried their institution's prospectively maintained craniofacial registry for nonsyndromic craniosynostosis patients aged 18 years and older, and administered the validated World Health Organization Quality of Life Biomedical Research and Education Foundation questionnaire. Responses were compared, using a two-sample t test, to an age-matched U.S. normative database provided by the World Health Organization. RESULTS: One hundred fifty-one adults met inclusion criteria: 52 were successfully contacted and 32 completed the questionnaire. Average age of respondents was 23.0 +/- 6.1 years (range, 18.1 to 42.1 years). Nonsyndromic craniosynostosis patients had a superior quality of life compared with comparative norms in all domains: physical health (17.8 +/- 2.7 versus 15.5 +/- 3.2; p < 0.001), psychological (16.3 +/- 2.9 versus 13.8 +/- 3.2; p < 0.001), social (16.9 +/- 2.6 versus 13.2 +/- 3.6; p < 0.001), and environmental (17.2 +/- 2.5 versus 11.7 +/- 2.7; p < 0.001). Comparison between single-suture subtypes revealed no difference in any quality-of-life domain (p > 0.05). CONCLUSIONS: Adult patients previously treated for nonsyndromic craniosynostosis perceive their quality of life to be high, superior to that of a normative U.S. SAMPLE: Future work will seek to analyze additional patients and better understand the reasons behind these findings. PMID- 29579021 TI - Genetics of Nonsyndromic Craniosynostosis. AB - Occurring once in every 2000 live births, craniosynostosis is one of the most frequent congenital anomalies encountered by the craniofacial surgeon. Syndromic craniosynostoses account for approximately 15 percent of cases and demonstrate Mendelian patterns of inheritance with well-established genetic causes; however, nonsyndromic craniosynostoses, which account for approximately 85 percent of cases, are genetically heterogeneous and largely unexplored. Nonsyndromic craniosynostosis is sporadic in more than 95 percent of affected families; thus, surgeons have suggested for decades that nonsyndromic craniosynostosis is likely a fluke occurrence. Contrary to this, recent studies have established that genetics underlie a substantial fraction of nonsyndromic craniosynostosis risk. Given the predominantly sporadic occurrence of disease, parents are often bewildered by the primary occurrence of nonsyndromic craniosynostosis or even recurrence in their own families and request genetic testing. Existing genetic testing panels are useful when the phenotype strongly resembles a known syndrome, wherein the risk of disease recurrence can be accurately predicted for future offspring of the parents and the future offspring of the affected child. The diagnostic utility of existing panels for nonsyndromic craniosynostosis, however, is extremely low, and these tests are quite costly. Recent genetic studies have identified several novel genes and pathways that cause nonsyndromic craniosynostosis, providing genetic evidence linking the causes of syndromic and nonsyndromic craniosynostoses, and allowing for genotype-based prediction of risk of recurrence in some nonsyndromic families. Based on analysis of exome sequence data from 384 families, the authors provide recommendations for a new genetic testing protocol for children with nonsyndromic craniosynostosis, which include testing nonsyndromic cases of sagittal, metopic, and coronal craniosynostosis. PMID- 29579022 TI - New Developments Are Improving Flexor Tendon Repair. AB - New developments in primary tendon repair in recent decades include stronger core tendon repair techniques, judicious and adequate venting of critical pulleys, followed by a combination of passive and active digital flexion and extension. During repair, core sutures over the tendon should have sufficient suture purchase (no shorter than 0.7 to 1 cm) in each tendon end and must be sufficiently tensioned to resist loosening and gap formation between tendon ends. Slight or even modest bulkiness in the tendon substance at the repair site is not harmful, although marked bulkiness should always be avoided. To expose the tendon ends and reduce restriction to tendon gliding, the longest annular pulley in the fingers (i.e., the A2 pulley) can be vented partially with an incision over its distal or proximal sheath no longer than 1.5 to 2 cm; the annular pulley over the middle phalanx (i.e., the A4 pulley) can be vented entirely. Surgeons have not observed adverse effects on hand function after judicious and limited venting. The digital extension-flexion test to check the quality of the repair during surgery has become increasingly routine. A wide-awake surgical setting allows patient to actively move the digits. After surgery, surgeons and therapists protect patients with a short splint and flexible wrist positioning, and are now moving toward out-of-splint freer early active motion. Improved outcomes have been reported over the past decade with minimal or no rupture during postoperative active motion, along with lower rates of tenolysis. PMID- 29579023 TI - Requirements for Successful Trachea Transplantation: A Study in the Rabbit Model. AB - BACKGROUND: Although creating a tracheal tube de novo might appear straightforward, the first clinical applications have shown that reconstruction of long-segment tracheal defects remains challenging. In this study, the authors aimed to refine the baseline requirements of successful trachea transplantation by means of three proof-of-concept models in the rabbit. METHODS: In each model, one characteristic of a perfect tracheal transplant was eliminated. The first model was developed to map out the immunologic response of vascularized allogenic trachea, transplanted without immunosuppression (n = 6). The second model studied (1) the need for wrapping the transplant with a highly vascularized flap and (2) the source of angiogenesis after autologous trachea transplantation (n = 18). In the third model, the authors examined the importance of an inner epithelial covering (n = 12). All models were compared to a control group of heterotopically transplanted vascularized autologous tracheae (n = 6). RESULTS: Embedded in an avascular matrix, allogenic chondrocytes were protected from an overt immune response. Orthotopic transplantation without additional external vascular wrap was successful in a well-vascularized environment. Nonetheless, an external vascular source was essential to maintain viability of the construct. Epithelial covering was necessary to prevent secondary healing. Epithelial migration from the anastomoses or graft was not sufficient to cover long-segment defects. CONCLUSIONS: These experiments provided ample evidence of the importance of baseline requirements when designing a tracheal transplant study. This study confirmed that different tracheal cell types possess different immunologic sensitivities. External revascularization, preferably in a two-stage procedure, and fast reepithelialization were both paramount to successful transplantation. PMID- 29579024 TI - Assessing Technical Performance and Determining the Learning Curve in Cleft Palate Surgery Using a High-Fidelity Cleft Palate Simulator. AB - BACKGROUND: This study assessed technical performance in cleft palate repair using a newly developed assessment tool and high-fidelity cleft palate simulator through a longitudinal simulation training exercise. METHODS: Three residents performed five and one resident performed nine consecutive endoscopically recorded cleft palate repairs using a cleft palate simulator. Two fellows in pediatric plastic surgery and two expert cleft surgeons also performed recorded simulated repairs. The Cleft Palate Objective Structured Assessment of Technical Skill (CLOSATS) and end-product scales were developed to assess performance. Two blinded cleft surgeons assessed the recordings and the final repairs using the CLOSATS, end-product scale, and a previously developed global rating scale. RESULTS: The average procedure-specific (CLOSATS), global rating, and end-product scores increased logarithmically after each successive simulation session for the residents. Reliability of the CLOSATS (average item intraclass correlation coefficient (ICC), 0.85 +/- 0.093) and global ratings (average item ICC, 0.91 +/- 0.02) among the raters was high. Reliability of the end-product assessments was lower (average item ICC, 0.66 +/- 0.15). Standard setting linear regression using an overall cutoff score of 7 of 10 corresponded to a pass score for the CLOSATS and the global score of 44 (maximum, 60) and 23 (maximum, 30), respectively. Using logarithmic best-fit curves, 6.3 simulation sessions are required to reach the minimum standard. CONCLUSIONS: A high-fidelity cleft palate simulator has been developed that improves technical performance in cleft palate repair. The simulator and technical assessment scores can be used to determine performance before operating on patients. PMID- 29579025 TI - A Novel Small-Animal Model of Irradiated, Implant-Based Breast Reconstruction. AB - BACKGROUND: There is currently a need for a clinically relevant small-animal model for irradiated, implant-based breast reconstruction. Present models are inadequate in terms of suboptimal location of expander placement and mode of radiation delivery, correlating poorly with the human clinical scenario. The authors hypothesized that by delivering fractionated radiation and placing an expander under the scalp of the animal, they would achieve soft-tissue changes histologically analogous to those seen in human irradiated, implant-based breast reconstruction. METHODS: This study consisted of 11 immunocompetent, hairless rats divided into three groups as follows: untreated control (n = 3), tissue expanded scalps (n = 4), and fractionated irradiation plus tissue expansion of the scalp (n = 4). At the completion of the experiment for each group, skin tissue samples were analyzed histologically for vascularity, epidermal and dermal thickness, and collagen fiber alignment or scar formation. RESULTS: Expanded rat epidermis was significantly thicker and dermis was more vascular than nonexpanded skin. The authors observed a greater degree of collagen fiber alignment in the expanded group compared with nonexpanded skin. The combination of irradiation and expansion resulted in significant dermal thinning, vascular depletion, and increased scar formation compared with expanded skin alone. CONCLUSIONS: The authors describe a novel small-animal model for irradiated, implant-based breast reconstruction where histologic analysis shows structural changes in the skin consistent with known effects of radiation therapy and expansion in human skin. This model represents a significant improvement from previous ones and, as such, holds the potential to be used to test new therapeutic agents to improve clinical outcomes. PMID- 29579026 TI - Targeted Muscle Reinnervation: Considerations for Future Implementation in Adolescents and Younger Children. AB - Prosthetic options for patients with proximal upper limb absence are limited. Current above-elbow prostheses may restore basic motor functions for crucial activities, but they are cumbersome to operate, lack sensory feedback, and are often abandoned. Targeted muscle reinnervation is a novel surgical procedure that enhances the ability of patients with above-elbow amputations to intuitively control a myoelectric prosthesis. By transferring multiple severed peripheral nerves to a robust target muscle, targeted muscle reinnervation restores physiologic continuity and enables more intuitive prosthetic control. Although reports have been limited to adults, targeted muscle reinnervation has great potential for application in a pediatric population with congenital or acquired proximal upper limb absence. In this review, the authors describe the rehabilitative challenges of proximal upper limb amputees and outline the objectives, techniques, and outcomes of targeted muscle reinnervation. The authors then discuss important considerations for adapting targeted muscle reinnervation to pediatric patients, including cause of upper limb absence, central plasticity, timing of prosthesis fitting, role of the family, surgical feasibility, and bioethical aspects. The authors believe that carefully screened school-age children and adolescents with bilateral proximal upper limb absence, and select adolescents with unilateral proximal upper limb absence, should be seriously considered for targeted muscle reinnervation performed by an experienced surgical and rehabilitation team.

AB - BACKGROUND: Nasal septal perforations pose a troubling source of morbidity for patients and a difficult problem for the otolaryngologist. Multiple surgical techniques have been tried, with inconsistent success. Prosthetic nasal buttons also have limitations, including patient intolerance and dissatisfaction. Acellular human dermal allograft (AlloDerm) has been described as an alternative material for septal perforation repair. The authors studied objective and subjective outcomes, including quantification of the patient's symptoms in septal perforation repair with AlloDerm. METHODS: The authors performed a prospective cohort study of 12 patients with 1- to 2-cm anterior septal perforations who were recruited from a tertiary care practice. Patients with admitted smoking or cocaine use in the previous 3 months or vascular or granulomatous diseases were excluded. Subjective scores on the Sino-nasal Outcome Test-22, along with objective nasal endoscopy and acoustic rhinometry measures, were collected at baseline and 2, 4, and 12 weeks postoperatively. Patients were followed for reperforation 9 to 20 months postoperatively. Data were normalized to baseline values and analyzed using analysis of variance and Bonferroni correction. RESULTS: Successful closure of the septal perforation was obtained in 10 of 12 patients and confirmed with rigid nasal endoscopy. Nasal symptom scores (Sino nasal Outcome Test-22 ) were significantly reduced to 52.8 percent (95 percent CI, 35.1 to 70.5 percent; p < 0.01) of baseline symptoms at 4 weeks postoperatively. At 12 weeks postoperatively, symptoms were measured at 26.6 percent (95 percent CI, 10.9 to 42.1 percent; p < 0.01) of baseline symptoms. Acoustic rhinometry confirmed perforation closure, demonstrating a reduction in cross-sectional nasal area from baseline of 55.1 percent (95 percent CI, 37.7 to 66.8 percent; p < 0.01). CONCLUSION: This is the first study to use objective and subjective measurements to confirm success with acellular dermis allograft as an adjunct for septal perforation repair, demonstrating a statistically significant reduction in patient nasal symptoms following repair.

AB - BACKGROUND: The 2010 American Joint Committee on Cancer guidelines recommended consideration of sentinel lymph node biopsy for thin melanoma (Breslow thickness <1.0 mm) with aggressive pathologic features such as ulceration and/or high mitotic rate. The therapeutic benefit of biopsy-based treatment remains controversial. The authors conducted a meta-analysis to estimate the risk and outcomes of sentinel lymph node positivity in thin melanoma, and examined established and potential novel predictors of positivity. METHODS: Three databases were searched by two independent reviewers for sentinel lymph node positivity in patients with thin melanoma. Study heterogeneity, publication bias, and quality were assessed. Data collected included age, sex, Breslow thickness, mitotic rate, ulceration, regression, Clark level, tumor-infiltrating lymphocytes, and vertical growth phase. Positivity was estimated using a random effects model. Association of positivity and clinicopathologic features was investigated using meta-regression. RESULTS: Ninety-three studies were identified representing 35,276 patients with thin melanoma who underwent sentinel lymph node biopsy. Of these patients, 952 had a positive sentinel lymph node biopsy, for an event rate of 5.1 percent (95 percent CI, 4.1 to 6.3 percent). Significant associations were identified between positivity and Breslow thickness greater than 0.75 mm but less than 1.0 mm, mitotic rate, ulceration, and Clark level greater than IV. Seven studies reported on vertical growth phase, which was strongly associated with positivity (OR, 4.3; 95 percent CI, 2.5 to 7.7). CONCLUSIONS: To date, this is the largest meta-analysis to examine predictors of sentinel lymph node biopsy positivity in patients with thin melanoma. Vertical growth phase had a strong association with biopsy positivity, providing support for its inclusion in standardized pathologic reporting.

AB - Diabetes increases the risk of cardiovascular diseases, which are the leading cause of mortality among diabetic patients. Although hyperglycemia is a major determinant of macrovascular and microvascular complications in diabetes, hypoglycemia and glycemic variability have also a strong influence on the cardiovascular system. This overview presents the current state of knowledge on the impact of type 2 diabetes on the cardiovascular system and new therapeutic strategies that have been recently developed to correct gluco-metabolic disturbances in patients with high cardiovascular risk, such as glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium-glucose cotransporter 2 (SGLT2) inhibitors. Results of several large randomized clinical trials (such as EMPA-REG, LEADER, SUSTAIN-6 and CANVAS) assessing the efficacy and safety of drugs based on new mechanisms deserve attention due to their beneficial impact on serious cardiovascular events, including cardiovascular death, myocardial infarction, and stroke. In addition, based on the results of recent studies and meta-analyses, an attempt was made to answer the questions of whether actions new drugs are mediated solely by the glucose lowering effect, and if indeed glycemic control affects the survival of patients with diabetes and cardiovascular risk, which seems of key importance from the clinical perspective. PMID- 29579036 TI - A mechanistic pan-cancer pathway model informed by multi-omics data interprets stochastic cell fate responses to drugs and mitogens. AB - Most cancer cells harbor multiple drivers whose epistasis and interactions with expression context clouds drug and drug combination sensitivity prediction. We constructed a mechanistic computational model that is context-tailored by omics data to capture regulation of stochastic proliferation and death by pan-cancer driver pathways. Simulations and experiments explore how the coordinated dynamics of RAF/MEK/ERK and PI-3K/AKT kinase activities in response to synergistic mitogen or drug combinations control cell fate in a specific cellular context. In this MCF10A cell context, simulations suggest that synergistic ERK and AKT inhibitor induced death is likely mediated by BIM rather than BAD, which is supported by prior experimental studies. AKT dynamics explain S-phase entry synergy between EGF and insulin, but simulations suggest that stochastic ERK, and not AKT, dynamics seem to drive cell-to-cell proliferation variability, which in simulations is predictable from pre-stimulus fluctuations in C-Raf/B-Raf levels. Simulations suggest MEK alteration negligibly influences transformation, consistent with clinical data. Tailoring the model to an alternate cell expression and mutation context, a glioma cell line, allows prediction of increased sensitivity of cell death to AKT inhibition. Our model mechanistically interprets context-specific landscapes between driver pathways and cell fates, providing a framework for designing more rational cancer combination therapy.

AB - In the context of an ageing population, understanding the transmission of infectious diseases such as scabies through well-connected sub-units of the population, such as residential care homes, is particularly important for the design of efficient interventions to mitigate against the effects of those diseases. Here, we present a modelling methodology based on the efficient solution of a large-scale system of linear differential equations that allows statistical calibration of individual-based random models to real data on scabies in residential care homes. In particular, we review and benchmark different numerical methods for the integration of the differential equation system, and then select the most appropriate of these methods to perform inference using Markov chain Monte Carlo. We test the goodness-of-fit of this model using posterior predictive intervals and propagate forward the resulting parameter uncertainty in a Bayesian framework to consider the economic cost of delayed interventions against scabies, quantifying the benefits of prompt action in the event of detection. We also revisit the previous methodology used to assess the safety of treatments in small population sub-units-in this context ivermectin-and demonstrate that even a very slight relaxation of the implicit assumption of homogeneous death rates significantly increases the plausibility of the hypothesis that ivermectin does not cause excess mortality based upon the data of Barkwell and Shields. PMID- 29579038 TI - Results of a confirmatory mapping tool for Lymphatic filariasis endemicity classification in areas where transmission was uncertain in Ethiopia. AB - BACKGROUND: The goal of the global lymphatic filariasis (LF) program is to eliminate the disease as a public health problem by the year 2020. The WHO mapping protocol that is used to identify endemic areas in need of mass drug administration (MDA) uses convenience-based sampling. This rapid mapping has allowed the global program to dramatically scale up treatment, but as the program approaches its elimination goal, it is important to ensure that all endemic areas have been identified and have received MDA. In low transmission settings, the WHO mapping protocol for LF mapping has several limitations. To correctly identify the LF endemicity of woredas, a new confirmatory mapping tool was developed to test older school children for circulating filarial antigen (CFA) in settings where it is uncertain. Ethiopia is the first country to implement this new tool. In this paper, we present the Ethiopian experience of implementing the new confirmatory mapping tool and discuss the implications of the results for the LF program in Ethiopia and globally. METHODS: Confirmatory LF mapping was conducted in 1,191 schools in 45 woredas, the implementation unit in Ethiopia, in the regions of Tigray, Amhara, Oromia, SNNP, Afar and Harari, where the results of previous mapping for LF using the current WHO protocol indicated that LF endemicity was uncertain. Within each woreda schools were selected using either cluster or systematic sampling. From selected schools, a total of 18,254 children were tested for circulating filarial antigen (CFA) using the immuno chromatographic test (ICT). RESULTS: Of the 18,254 children in 45 woredas who participated in the survey, 28 (0.16%) in 9 woredas tested CFA positive. According to the confirmatory mapping threshold, which is >=2% CFA in children 9 14 years of age, only 3 woredas out of the total 45 had more CFA positive results than the threshold and thus were confirmed to be endemic; the remaining 42 woredas were declared non-endemic. These results drastically decreased the estimated total population living in LF-endemic woredas in Ethiopia and in need of MDA by 49.1%, from 11,580,010 to 5,893,309. CONCLUSION: This study demonstrated that the new confirmatory mapping tool for LF can benefit national LF programs by generating information that not only can confirm where LF is endemic, but also can save time and resources by preventing MDA where there is no evidence of ongoing LF transmission. PMID- 29579039 TI - AMYCNE: Confident copy number assessment using whole genome sequencing data. AB - Copy number variations (CNVs) within the human genome have been linked to a diversity of inherited diseases and phenotypic traits. The currently used methodology to measure copy numbers has limited resolution and/or precision, especially for regions with more than 4 copies. Whole genome sequencing (WGS) offers an alternative data source to allow for the detection and characterization of the copy number across different genomic regions in a single experiment. A plethora of tools have been developed to utilize WGS data for CNV detection. None of these tools are designed specifically to accurately estimate copy numbers of complex regions in a small cohort or clinical setting. Herein, we present AMYCNE (automatic modeling functionality for copy number estimation), a CNV analysis tool using WGS data. AMYCNE is multifunctional and performs copy number estimation of complex regions, annotation of VCF files, and CNV detection on individual samples. The performance of AMYCNE was evaluated using AMY1A ddPCR measurements from 86 unrelated individuals. In addition, we validated the accuracy of AMYCNE copy number predictions on two additional genes (FCGR3A and FCGR3B) using datasets available through the 1000 genomes consortium. Finally, we simulated levels of mosaic loss and gain of chromosome X and used this dataset for benchmarking AMYCNE. The results show a high concordance between AMYCNE and ddPCR, validating the use of AMYCNE to measure tandem AMY1 repeats with high accuracy. This opens up new possibilities for the use of WGS for accurate copy number determination of other complex regions in the genome in small cohorts or single individuals.

AB - As the most widespread tick-borne arbovirus causing infections in numerous countries in Asia, Africa and Europe, Crimean-Congo Hemorrhagic Fever Virus (CCHFV, family Nairoviridae) was included in the WHO priority list of emerging pathogens needing urgent Research & Development attention. To ensure preparedness for potential future outbreak scenarios, reliable diagnostic tools for identification of acute cases as well as for performance of seroprevalence studies are necessary. Here, the CCHFV ortholog of the major bunyavirus antigen, the nucleoprotein (NP), was recombinantly expressed in E.coli, purified and directly labeled with horseradish peroxidase (HRP). Employing this antigen, two serological tests, a MU-capture ELISA for the detection of CCHFV-specific IgM antibodies (BLACKBOX CCHFV IgM) and an IgG immune complex (IC) ELISA for the detection of CCHFV-specific IgG antibodies (BLACKBOX CCHFV IgG), were developed. Test performance was evaluated and compared with both in-house gold standard testing by IgM/IgG indirect immunofluorescence (IIF) and commercially available ELISA tests (VectoCrimean-CHF-IgM/IgG, Vector-Best, Russia) using a serum panel comprising paired samples collected in Kosovo during the years 2013-2016 from 15 patients with an acute, RT-PCR-confirmed CCHFV infection, and 12 follow-up sera of the same patients collected approximately one year after having overcome the infection. Reliably detecting IgM antibodies in all acute phase sera collected later than day 4 after onset of symptoms, both IgM ELISAs displayed excellent diagnostic and analytical sensitivity (100%, 95% confidence interval (CI): 85.2% 100.0%). While both IgG ELISAs readily detected the high IgG titers present in convalescent patients approximately one year after having overcome the infection (sensitivity 100%, 95% CI: 73.5%-100.0%), the newly developed BLACKBOX CCHFV IgG ELISA was superior to the commercial IgG ELISA in detecting the rising IgG titers during the acute phase of the disease. While all samples collected between day 11 and 19 after onset of symptoms tested positive in both the in-house gold standard IIFT and the BLACKBOX CCHFV IgG ELISA (sensitivity 100%, 95% CI: 71.5%-100.0%), only 27% (95% CI: 6.0%-61.0%) of those samples were tested positive in the commercial IgG ELISA. No false positive signals were observed in either IgM/IgG ELISA when analyzing a priori CCHFV IgM/IgG negative serum samples from healthy blood donors, malaria patients and flavivirus infected patients as well as CCHFV IgM/IgG IIFT negative serum samples from healthy Kosovar blood donors (for BLACKBOX CCHFV IgM/IgG: n = 218, 100% specificity, 95% CI: 98.3%-100.0%, for VectoCrimean-CHF-IgM/IgG: n = 113, 100% specificity, 95% CI: 96.8%-100.0%). PMID- 29579041 TI - The CSR-1 endogenous RNAi pathway ensures accurate transcriptional reprogramming during the oocyte-to-embryo transition in Caenorhabditis elegans. AB - Endogenous RNAi (endoRNAi) is a conserved mechanism for fine-tuning gene expression. In the nematode Caenorhabditis elegans, several endoRNAi pathways are required for the successful development of reproductive cells. The CSR-1 endoRNAi pathway promotes germ cell development, primarily by facilitating the expression of germline genes. In this study, we report a novel function for the CSR-1 pathway in preventing premature activation of embryonic transcription in the developing oocytes, which is accompanied by a general Pol II activation. This CSR 1 function requires its RNase activity, suggesting that, by controlling the levels of maternal mRNAs, CSR-1-dependent endoRNAi contributes to an orderly reprogramming of transcription during the oocyte-to-embryo transition. PMID- 29579042 TI - Genetic variants in cellular transport do not affect mesalamine response in ulcerative colitis. AB - BACKGROUND AND AIMS: Mesalamine is commonly used to treat ulcerative colitis (UC). Although mesalamine acts topically, in vitro data suggest that intracellular transport is required for its beneficial effect. Genetic variants in mucosal transport proteins may affect this uptake, but the clinical relevance of these variants has not been studied. The aim of this study was to determine whether variants in genes involved in cellular transport affect the response to mesalamine in UC. METHODS: Subjects with UC from a 6-week clinical trial using multiple doses of mesalamine were genotyped using a genome-wide array that included common exome variants. Analysis focused on cellular transport gene variants with a minor allele frequency >5%. Mesalamine response was defined as improvement in Week 6 Physician's Global Assessment (PGA) and non-response as a lack of improvement in Week 6 PGA. Quality control thresholds included an individual genotyping rate of >90%, SNP genotyping rate of >98%, and exclusion for subjects with cryptic relatedness. All included variants met Hardy-Weinberg equilibrium (p>0.001). RESULTS: 457 adults with UC were included with 280 responders and 177 non-responders. There were no common variants in transporter genes that were associated with response to mesalamine. The genetic risk score of responders was similar to that of non-responders (p = 0.18). Genome-wide variants demonstrating a trend towards mesalamine response included ST8SIA5 (p = 1x10-5). CONCLUSIONS: Common transporter gene variants did not affect response to mesalamine in adult UC. The response to mesalamine may be due to rare genetic events or environmental factors such as the intestinal microbiome. PMID- 29579043 TI - Experiments in interdisciplinarity: Responsible research and innovation and the public good. AB - In Europe, responsible research and innovation (RRI) has emerged as a science policy measure that demands the early integration of a broad range of social actors and perspectives into research and development (R&D). More collaboration of the social sciences and humanities (SSH) with science and engineering appears within this policy framework as a crucial element that will enable better technological development. However, RRI is new to both natural scientists and SSH scholars, and interdisciplinary collaborations are challenging for many reasons. In this paper, we discuss these challenges while suggesting that what RRI can be in a particular project is not a given but remains an empirical question. Natural scientists and SSH scholars need to coresearch RRI in an experimental mode. PMID- 29579045 TI - From correlation to causation: Estimating effective connectivity from zero-lag covariances of brain signals. AB - Knowing brain connectivity is of great importance both in basic research and for clinical applications. We are proposing a method to infer directed connectivity from zero-lag covariances of neuronal activity recorded at multiple sites. This allows us to identify causal relations that are reflected in neuronal population activity. To derive our strategy, we assume a generic linear model of interacting continuous variables, the components of which represent the activity of local neuronal populations. The suggested method for inferring connectivity from recorded signals exploits the fact that the covariance matrix derived from the observed activity contains information about the existence, the direction and the sign of connections. Assuming a sparsely coupled network, we disambiguate the underlying causal structure via L1-minimization, which is known to prefer sparse solutions. In general, this method is suited to infer effective connectivity from resting state data of various types. We show that our method is applicable over a broad range of structural parameters regarding network size and connection probability of the network. We also explored parameters affecting its activity dynamics, like the eigenvalue spectrum. Also, based on the simulation of suitable Ornstein-Uhlenbeck processes to model BOLD dynamics, we show that with our method it is possible to estimate directed connectivity from zero-lag covariances derived from such signals. In this study, we consider measurement noise and unobserved nodes as additional confounding factors. Furthermore, we investigate the amount of data required for a reliable estimate. Additionally, we apply the proposed method on full-brain resting-state fast fMRI datasets. The resulting network exhibits a tendency for close-by areas being connected as well as inter hemispheric connections between corresponding areas. In addition, we found that a surprisingly large fraction of more than one third of all identified connections were of inhibitory nature. PMID- 29579044 TI - Suppressed plasmablast responses in febrile infants, including children with Kawasaki disease. AB - BACKGROUND: Kawasaki disease (KD), the leading cause of acquired heart disease in children, primarily affects infants and toddlers. Investigations on immune responses during KD are hampered by a limited understanding of normal immune responses in these ages. It's well known that Infants have poorer vaccine responses and difficulty with maintaining prolonged serum immunity, but there are few studies on human infants detailing immune deficiencies. Limited studies propose an inability to maintain life-long bone marrow plasma cells. Plasmablasts are a transitional cell form of B cells that lead to long-term Plasma cells. Plasmablasts levels rise in the peripheral blood after exposure to a foreign antigen. In adult studies, these responses are both temporally and functionally well characterized. To date, there have been few studies on plasmablasts in the predominant age range of KD. METHODS: Children presenting to an urban pediatric emergency room undergoing laboratory evaluation, who had concern of KD or had fever and symptoms overlapping those of KD, were recruited. Peripheral blood mononuclear cells were isolated and evaluated utilizing flow cytometry with specific B cell markers from 18 KD subjects and 69 febrile controls. RESULTS: Plasmablast numbers and temporal formation are similar between infectious disease controls and KD subjects. In both groups, infants have diminished plasmablast responses compared to older children. CONCLUSION: In this single-time point survey, infants have a blunted peripheral plasmablast response. Overall, similar plasmablast responses in KD and controls support an infectious disease relationship to KD. Future time-course studies of plasmablasts in infants are warranted as this phenomenon may contribute to observed immune responses in this age group. PMID- 29579046 TI - Scrub typhus point-of-care testing: A systematic review and meta-analysis. AB - BACKGROUND: Diagnosing scrub typhus clinically is difficult, hence laboratory tests play a very important role in diagnosis. As performing sophisticated laboratory tests in resource-limited settings is not feasible, accurate point-of care testing (POCT) for scrub typhus diagnosis would be invaluable for patient diagnosis and management. Here we summarise the existing evidence on the accuracy of scrub typhus POCTs to inform clinical practitioners in resource-limited settings of their diagnostic value. METHODOLOGY/PRINCIPAL FINDINGS: Studies on POCTs which can be feasibly deployed in primary health care or outpatient settings were included. Thirty-one studies were identified through PubMed and manual searches of reference lists. The quality of the studies was assessed with the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). About half (n = 14/31) of the included studies were of moderate quality. Meta-analysis showed the pooled sensitivity and specificity of commercially available immunochromatographic tests (ICTs) were 66.0% (95% CI 0.37-0.86) and 92.0% (95% CI 0.83-0.97), respectively. There was a significant and high degree of heterogeneity between the studies (I2 value = 97.48%, 95% CI 96.71-98.24 for sensitivity and I2 value = 98.17%, 95% CI 97.67-98.67 for specificity). Significant heterogeneity was observed for total number of samples between studies (p = 0.01), study design (whether using case-control design or not, p = 0.01), blinding during index test interpretation (p = 0.02), and QUADAS-2 score (p = 0.01). CONCLUSIONS/SIGNIFICANCE: There was significant heterogeneity between the scrub typhus POCT diagnostic accuracy studies examined. Overall, the commercially available scrub typhus ICTs demonstrated better performance when 'ruling in' the diagnosis. There is a need for standardised methods and reporting of diagnostic accuracy to decrease between-study heterogeneity and increase comparability among study results, as well as development of an affordable and accurate antigen-based POCT to tackle the inherent weaknesses associated with serological testing. PMID- 29579048 TI - Oxygen-sensing neurons reciprocally regulate peripheral lipid metabolism via neuropeptide signaling in Caenorhabditis elegans. AB - The mechanisms by which the sensory environment influences metabolic homeostasis remains poorly understood. In this report, we show that oxygen, a potent environmental signal, is an important regulator of whole body lipid metabolism. C. elegans oxygen-sensing neurons reciprocally regulate peripheral lipid metabolism under normoxia in the following way: under high oxygen and food absence, URX sensory neurons are activated, and stimulate fat loss in the intestine, the major metabolic organ for C. elegans. Under lower oxygen conditions or when food is present, the BAG sensory neurons respond by repressing the resting properties of the URX neurons. A genetic screen to identify modulators of this effect led to the identification of a BAG-neuron-specific neuropeptide called FLP-17, whose cognate receptor EGL-6 functions in URX neurons. Thus, BAG sensory neurons counterbalance the metabolic effect of tonically active URX neurons via neuropeptide communication. The combined regulatory actions of these neurons serve to precisely tune the rate and extent of fat loss to the availability of food and oxygen, and provides an interesting example of the myriad mechanisms underlying homeostatic control. PMID- 29579047 TI - Bioinformatic characterization of the Anoctamin Superfamily of Ca2+-activated ion channels and lipid scramblases. AB - Our laboratory has developed bioinformatic strategies for identifying distant phylogenetic relationships and characterizing families and superfamilies of transport proteins. Results using these tools suggest that the Anoctamin Superfamily of cation and anion channels, as well as lipid scramblases, includes three functionally characterized families: the Anoctamin (ANO), Transmembrane Channel (TMC) and Ca2+-permeable Stress-gated Cation Channel (CSC) families; as well as four families of functionally uncharacterized proteins, which we refer to as the Anoctamin-like (ANO-L), Transmembrane Channel-like (TMC-L), and CSC-like (CSC-L1 and CSC-L2) families. We have constructed protein clusters and trees showing the relative relationships among the seven families. Topological analyses suggest that the members of these families have essentially the same topologies. Comparative examination of these homologous families provides insight into possible mechanisms of action, indicates the currently recognized organismal distributions of these proteins, and suggests drug design potential for the disease-related channel proteins. PMID- 29579049 TI - Fecal microbiota in the female prairie vole (Microtus ochrogaster). AB - We examined the fecal microbiota of female prairie voles. This species is socially and, likely, sexually monogamous, and thus serves as a valuable model in which to examine the interaction between the microbiota-gut-brain axis and social behavior. At present, little is known about the gastrointestinal microbiota of prairie voles; therefore, we performed a first characterization of the fecal microbiota using 16S rRNA gene amplicon sequencing. Semiconductor sequencing technology on an Ion Torrent PGM platform was used to assess the composition of fecal microbiotas from twelve female prairie voles. Following quality filtering, 1,017,756 sequencing reads were classified from phylum to genus level. At the phylum level, Firmicutes, Bacteroidetes, and Saccharibacteria were the predominant taxa, while the Bacteriodales, Erysipelotrichaceae, Ruminococcaceae, and Lachnospiraceae contributed the most dominant microbial groups and genera. Microbial community membership was most similar between vole sibling pairs, but consideration of taxon abundances weakened these associations. The interdependence of host factors such as genetics and behavior with the gastrointestinal microbiota is likely to be particularly pronounced in prairie voles. Our pilot characterization of the prairie vole intestinal microbiota revealed a microbial community composition remarkably consistent with the monogastric alimentary system of these rodents and their diet rich in complex plant carbohydrates. The highly social nature of these animals poses specific challenges to microbiome analyses that nonetheless are valuable for advancing research on the microbiota-gut-brain-behavior axis. Our study provides an important basis for future microbiome research in this emerging model organism for studying social behavior.

AB - The disease burden of Wuchereria bancrofti and Plasmodium falciparum malaria is high, particularly in Africa, and co-infection is common. However, the effects of filarial infection on the risk of severe malaria are unknown. We used the remaining serum samples from a large cohort study in Muheza, Tanzania to describe vector-borne filarial sero-reactivity among young children and to identify associations between exposure to filarial parasites and subsequent severe malaria infections. We identified positive filarial antibody responses (as well as positive antibody responses to Strongyloides stercoralis) among infants as young as six months. In addition, we found a significant association between filarial seropositivity at six months of age and subsequent severe malaria. Specifically, infants who developed severe malaria by one year of age were 3.9 times more likely (OR = 3.9, 95% CI: 1.2, 13.0) to have been seropositive for filarial antigen at six months of age compared with infants who did not develop severe malaria. PMID- 29579051 TI - Eutrophication and predator presence overrule the effects of temperature on mosquito survival and development. AB - Adequate predictions of mosquito-borne disease risk require an understanding of the relevant drivers governing mosquito populations. Since previous studies have focused mainly on the role of temperature, here we assessed the effects of other important ecological variables (predation, nutrient availability, presence of conspecifics) in conjunction with the role of temperature on mosquito life history parameters. We carried out two mesocosm experiments with the common brown house mosquito, Culex pipiens, a confirmed vector for West Nile Virus, Usutu and Sindbis, and a controphic species; the harlequin fly, Chironomus riparius. The first experiment quantified interactions between predation by Notonecta glauca L. (Hemiptera: Notonectidae) and temperature on adult emergence. The second experiment quantified interactions between nutrient additions and temperature on larval mortality and adult emergence. Results indicate that 1) irrespective of temperature, predator presence decreased mosquito larval survival and adult emergence by 20-50%, 2) nutrient additions led to a 3-4-fold increase in mosquito adult emergence and a 2-day decrease in development time across all temperature treatments, 3) neither predation, nutrient additions nor temperature had strong effects on the emergence and development rate of controphic Ch. riparius. Our study suggests that, in addition to of effects of temperature, ecological bottom up (eutrophication) and top-down (predation) drivers can have strong effects on mosquito life history parameters. Current approaches to predicting mosquito-borne disease risk rely on large-scale proxies of mosquito population dynamics, such as temperature, vegetation characteristics and precipitation. Local scale management actions, however, will require understanding of the relevant top-down and bottom up drivers of mosquito populations.

PMID- 29579053 TI - Emergence of opinion leaders in reference networks. AB - Individuals often refer to opinions of others when they make decisions in the real world. Our question is how the people's reference structure self-organizes when people try to provide correct answers by referring to more accurate agents. We constructed an adaptive network model, in which each node represents an agent and each directed link represents a reference. In every iteration round within our model, each agent makes a decision sequentially by following the majority of the reference partners' opinions and rewires a reference link to a partner if the partner's performance falls below a given threshold. The value of this threshold is common for all agents and represents the performance assessment severity of the population. We found that the reference network self-organizes into a heterogeneous one with a nearly exponential in-degree (the number of followers) distribution, where reference links concentrate around agents with high intrinsic ability. In this heterogeneous network, the decision-making accuracy of agents improved on average. However, the proportion of agents who provided correct answers showed strong temporal fluctuation compared to that observed in the case in which each agent refers to randomly selected agents. We also found a counterintuitive phenomenon in which reference links concentrate more around high ability agents and the population became smarter on average when the rewiring threshold was set lower than when it was set higher. PMID- 29579054 TI - The expression and function of KCNQ potassium channels in human chorionic plate arteries from women with normal pregnancies and pre-eclampsia. AB - Pre-eclampsia is associated with altered maternal and placental vascular reactivity. Kv7 channels (encoded by KCNQ 1-5 genes) are a potential contributor to the regulation of vascular tone in CPAs (chorionic plate arteries) during normal pregnancy. The aim of this study is to establish the expression profile of KCNQ subunits in CPAs taken from women with preeclampsia or normotensive women and to examine the functional relevance of the Kv7 channels on an altered expression profile of KCNQ subunits. The effects of Kv7 channel modulators on CPAs were investigated by tension measurement. Quantitative PCR experiments were used to analyze the expression of KCNQ genes. Western blotting and immunofluorescence were both used to analyze the protein expression of Kv7 channels. Finally, in CPAs from normotensive women, the Kv7 channel blocker XE991 increased arterial basal tone and U46619-induced contraction, and pre-contracted CPAs (10-7 M U46619) exhibited significant relaxation following treatment with Retigabine(Kv7.2-7.5 activator) and BMS-204352(Kv7.2-7.5 activator). However, ICA 27243(selective KCNQ2 and KCNQ3 activator) and ML277(selective KV7.1 activator) had no significant effect on tension in the pre-contracted CPAs. Conversely, compared with CPAs from normotensive women, the effects of XE991 on basal tone and agonist (U46619)-induced contractions in CPAs from women with preeclampsia were markedly attenuated. Moreover, the relaxation effects of Retigabine and BMS 204352 on pre-contracted CPA vessels from women with pre-eclampsia were also markedly down-regulated. Interestingly, the relaxation ability of ICA-27243 in pre-contracted CPA vessels in women with pre-eclampsia was enhanced. The mRNA of KCNQ3 was specifically up-regulated, whereas those for KCNQ4 and KCNQ5 were down regulated in CPAs from women with pre-eclampsia compared with those in normotensive women. Similar observations were found in a subsequent analysis of protein expression of KCNQ genes 3-5. Thus, down-regulated Kv7 channel function in tension regulation of CPAs in women with pre-eclampsia could be associated with considerably altered expression profiles of Kv7 subunits. PMID- 29579055 TI - Proportion and predictors of transfusion-transmissible infections among blood donors in North Shewa Zone, Central North Ethiopia. AB - BACKGROUND: Transfusion-transmissible infections (TTIs) pose a significant challenge for the availability and safety of blood transfusion. The aim of this study was to investigate the prevalence and risk factors for TTIs among blood donors in North Shewa zone, central North Ethiopia. METHODS: A retrospective survey of blood donors' medical records was conducted from April 2014 to June 2017 to assess the presence of hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and syphilis infections. Descriptive statistics such as percentage, median and interquartile range were used to summarize the data. RESULTS: Out of 8460 donations, 207 (2.4%, 95% CI 2.06-2.71%) had serological evidence of infection with at least one pathogen. Four of the blood donors (0.047%) had co-infection with more than one pathogen; 2HIV/HBV and 2HIV/syphilis. The overall prevalence of HBV, HCV, HIV, and syphilis among the donors were 1.2% (95% CI 0.98-1.45%), 0.32% (95% CI 0.2-0.44%), 0.25% (95% CI 0.14-0.35%), and 0.71% (95% CI 0.53-0.89%) respectively. Male sex was significantly associated with higher risk of HBV (OR 1.75, 95% CI 1.1-2.8) and syphilis sero-reactivity (OR 4.5, 95% CI1.9-10.5). Farmers and older donors were found to be at a higher risk for syphilis seropositivity. CONCLUSION: The prevalence of TTIs among blood donors in North Shewa zone was relatively low compared to those of other geographic places in Ethiopia. However, TTIs remain a concern for the availability and safety of blood transfusion as they are still prevalent in the study area. Therefore, more efforts are required to ensure the safety of blood supply and transfusions. PMID- 29579056 TI - Empathizing-systemizing cognitive styles: Effects of sex and academic degree. AB - This study tests if the drives to empathize (E) and systemize (S), measured by the Systemizing Quotient-Revised (SQ-R) and Empathy Quotient (EQ), show effects of sex and academic degree. The responses of 419 students from the Humanities and the Physical Sciences were analyzed in terms of the E-S theory predictions. Results confirm that there is an interaction between sex, degree and the drive to empathize relative to systemize. Female students in the Humanities on average had a stronger drive to empathize than to systemize in comparison to males in the Humanities. Male students in the Sciences on average had a stronger drive to systemize than to empathize in comparison to females in the Sciences. Finally, students in the sciences on average had a stronger drive to systemize more than to empathize, irrespective of their sex. The reverse is true for students in the Humanities. These results strongly replicate earlier findings. PMID- 29579057 TI - Exacerbation induces a microbiota shift in sputa of COPD patients. AB - Little is known about the microbiota shift induced by exacerbation in chronic obstructive pulmonary disease (COPD) patients. The sputa microbiota of COPD patients was evaluated when clinically stable and during acute exacerbations of the disease. Sputa microbiota was analyzed using 16S ribosomal RNA gene pyrosequencing and quantitative polymerase chain reaction-based pathogen detection. Nine COPD patients were enrolled. Pyrosequencing of 16S rRNA genes identified 2,267 unique bacterial operational taxonomic units. Principal microbiota shifts during exacerbation were in either Proteobacteria, Firmicutes or Bacteroidetes. Streptococcus and Moraxella levels were detected during exacerbation in severe (Global Initiative for Chronic Obstructive Lung Disease 3) COPD patients. Most of the clinically-important genera found in the sputum with the pyrosequencing of 16S rRNA gene correlated with specific quantitative polymerase chain reactions for bacteria while respiratory viruses were nearly absent. Sputum microbiotas of exacerbated COPD patients are complex. This pilot study shows a clear shift in the microbiota of patients during exacerbation. The nature of this shift varies from patient to patient in such a way that the treatment should be patient-specific. Further studies are needed to establish the impact of microbial exacerbations on the pulmonary microbiota. PMID- 29579058 TI - Comparative oncology approach to drug repurposing in osteosarcoma. AB - BACKGROUND: Osteosarcoma is an orphan disease for which little improvement in survival has been made since the late 1980s. New drug discovery for orphan diseases is limited by the cost and time it takes to develop new drugs. Repurposing already approved FDA-drugs can help overcome this limitation. Another limitation of cancer drug discovery is the lack of preclinical models that accurately recapitulate what occurs in humans. For OS using dogs as a model can minimize this limitation as OS in canines develops spontaneously, is locally invasive and metastasizes to the lungs as it does in humans. METHODS: In our present work we used high-throughput screens to identify drugs from a library of 2,286 FDA-approved drugs that demonstrated selective growth inhibition against both human and canine OS cell lines. The identified lead compound was then tested for synergy with 7 other drugs that have demonstrated activity against OS. These results were confirmed with in vitro assays and an in vivo murine model of OS. RESULTS: We identified 13 drugs that demonstrated selective growth inhibition against both human and canine OS cell lines. Auranofin was selected for further in vitro combination drug screens. Auranofin showed synergistic effects with vorinostat and rapamycin on OS viability and apoptosis induction. Auranofin demonstrated single-agent growth inhibition in both human and canine OS xenografts, and cooperative growth inhibition was observed in combination with rapamycin or vorinostat. There was a significant decrease in Ki67-positive cells and an increase in cleaved caspase-3 levels in tumor tissues treated with a combination of auranofin and vorinostat or rapamycin. CONCLUSIONS: Auranofin, alone or in combination with rapamycin or vorinostat, may be useful new treatment strategies for OS. Future studies may evaluate the efficacy of auranofin in dogs with OS as a prelude to human clinical evaluation. PMID- 29579059 TI - Cardiac findings in infants with in utero exposure to Zika virus- a cross sectional study. AB - BACKGROUND: Antenatal exposure to Zika virus (ZIKV) is related to severe neurological manifestations. A previous study in Brazil reported an increased incidence of non-severe congenital heart defects in infants with diagnosis of congenital Zika syndrome but without laboratory confirmation of ZIKV infection in the mother or infant. The objective of this study is to report echocardiographic (ECHO) findings in infants with laboratory confirmed antenatal exposure to ZIKV. METHODOLOGY: Cross sectional study of cardiologic assessments of infants born between November 2015 and January 2017 with confirmed vertical exposure to ZIKV in Rio de Janeiro, Brazil. RESULTS: The study enrolled 120 children with a median age of 97 days (1 to 376 days). In utero exposure to ZIKV was confirmed in 97 children (80,8%) through positive maternal polymerase chain reaction (PCR) results during pregnancy or a positive PCR result at birth; 23 additional children (19.2%) had maternal positive PCR results during pregnancy and postnatally. Forty- eight infants (40%) had cardiac defects noted on ECHO. Thirteen infants (10.8%) had major cardiac defects (atrial septal defect, ventricular septal defect, patent ductus arteriosus). None of the defects were severe. The frequency of major defects was higher in infants whose mothers had a rash in the 2nd trimester of pregnancy, or who had altered Central Nervous System (CNS) imaging postnatally or were preterm. CONCLUSIONS: Infants with in utero ZIKV exposure have a higher prevalence of major cardiac defects, however none were severe enough to require immediate intervention. For this reason, guidelines for performance of postnatal ECHO in this population should follow general newborn screening guidelines, which significantly reduces the burden of performing emergent fetal or neonatal ECHOs in a setting where resources are not available, such as most Brazilian municipalities. PMID- 29579061 TI - Effects of cognitive impairment and functional limitation on depressive symptoms among community-dwelling older Korean immigrants in the U.S. AB - The present study examined the effects of cognitive impairment and functional limitation on depressive symptoms among older Korean American immigrants. The sample was drawn from a cross-sectional survey of 210 older Korean immigrants (aged 65 years or older) in Los Angeles County. Based on robust hierarchical regression, the study found that cognitive ability and functional status were significant explanatory factors related to depressive symptoms among older Korean immigrants. In addition, the interaction of instrumental activities of daily living (IADL) and cognitive function (MMSE) had a significant effect on depressive symptoms. This finding suggests that older Korean immigrants in the U.S. who experience deficits in cognitive function and/or IADL performance are vulnerable to psychological distress as indicated by depressive symptoms. Recommendations include implementing culturally-responsive health interventions aimed at enabling accessibility to dementia care services and supporting improvement of IADL performance among older Korean American immigrants. PMID- 29579060 TI - Role of oceanography in shaping the genetic structure in the North Pacific hake Merluccius productus. AB - Determining the relative influence of biotic and abiotic factors on genetic connectivity among populations remains a major challenge in evolutionary biology and in the management and conservation of species. North Pacific hake (Merluccius productus) inhabits upwelling regions in the California Current ecosystem from the Gulf of California to the Gulf of Alaska. In this study, we examined mitochondrial DNA (mtDNA) and microsatellite variation to estimate levels of genetic differentiation of M. productus in relation to the role of oceanographic features as potential barriers to gene flow. Samples were obtained from nine sites spanning a large part of the geographic range of the species, from Puget Sound, Washington to Costa Rica. The microsatellite results revealed three genetically discrete populations: one spanning the eastern Pacific coast, and two apparently resident populations circumscribed to the Puget Sound and the northern Gulf of California (FST = 0.032, p = 0.036). Cytochrome b sequence data indicated that isolation between the Puget Sound and northern Gulf of California populations from the coastal Pacific were recent phenomena (18.5 kyr for Puget Sound and 40 kyr for the northern Gulf of California). Oceanographic data obtained from the Gulf of California support the hypothesis that permanent fronts within the region, and strong gradients at the entrance to the Gulf of California act as barriers to gene flow. A seascape genetics approach found significant genetic-environment associations, where the daytime sea surface temperature and chlorophyll concentrations were the best predictive variables for the observed genetic differentiation. Considering the potential causes of genetic isolation among the three populations, e.g. spawning areas in different latitudes associated with upwelling processes, oceanographic barriers, asymmetric migration and specialized diet, oceanographic barriers appear to be a likely mechanism restricting gene flow. PMID- 29579062 TI - Heterogeneity in glycan composition on the surface of HIV-1 envelope determines virus sensitivity to lectins. AB - Lectins that target N-glycans on the surface of HIV-1 envelope (Env) glycoprotein have the potential for use as antiviral agents. Although progress has been made in deciphering the molecular details of lectin and Env glycan interaction, further studies are needed to better understand Env glycan heterogeneity among HIV-1 isolates and its influence on virus-neutralization sensitivity to lectins. This study evaluated a panel of lectins with fine specificity for distinct oligosaccharides and assessed their ability to inhibit infection of HIV-1 viruses known to have differing sensitivity to anti-HIV Env antibodies. The results showed that HIV-1 isolates have different sensitivity to lectins specific for alpha1-3Man, alpha1-6Man, and alpha1-2Man binding lectins. Considering that lectins exclusively recognize the oligosaccharide components of virus Env, these data suggest that glycan heterogeneity among HIV-1 isolates may explain this differential sensitivity. To evaluate this further, chronic and acute viruses were produced in the presence of different glycosidase inhibitors to express more homogenous glycans. Viruses enriched for alpha1-2Man terminating Man5-9GlcNAc2 glycans became similarly sensitive to alpha1-2Man-binding lectins. The alpha1 3Man- and alpha1-6Man-binding lectins also were more potent against viruses expressing predominantly Man5GlcNAc2 and hybrid type glycans with terminal alpha1 3Man and alpha1-6Man. Furthermore, lectin-mediated inhibition was competitively alleviated by mannan and this effect was augmented by enrichment of mannose-type glycans on the virus. In addition, while Env of viruses enriched with mannose type glycans were sensitive to Endo-H deglycosylation, Env of untreated viruses were partially resistant, indicating that HIV-1 Env glycans are heterogeneously comprised of complex, hybrid, and mannose types. Overall, our data demonstrate that HIV-1 isolates display differential sensitivity to lectins, in part due to the microheterogeneity of N-linked glycans expressed on the surface of the virus Env glycoprotein. PMID- 29579064 TI - Neural processing of food and emotional stimuli in adolescent and adult anorexia nervosa patients. AB - BACKGROUND: A constant preoccupation with food and restrictive eating are main symptoms of anorexia nervosa (AN). Imaging studies revealed aberrant neural activation patterns in brain regions processing hedonic and reward reactions as well as-potentially aversive-emotions. An imbalance between so called "bottom-up" and "top-down" control areas is discussed. The present study is focusing on neural processing of disease-specific food stimuli and emotional stimuli and its developmental course in adolescent and adult AN patients and could offer new insight into differential mechanisms underlying shorter or more chronic disease. METHODS: 33 adolescents aged 12-18 years (15 AN patients, 18 control participants) and 32 adult women (16 AN patients, 16 control participants) underwent functional magnetic resonance imaging (fMRI, 3T high-field scanner) while watching pictures of high and low-calorie food and affective stimuli. Afterwards, they rated subjective valence of each picture. FMRI data analysis was performed using a region of interest based approach. RESULTS: Pictures of high calorie food items were rated more negatively by AN patients. Differences in activation between patients and controls were found in "bottom up" and "top down" control areas for food stimuli and in several emotion processing regions for affective stimuli which were more pronounced in adolescents than in adults. CONCLUSION: A differential pattern was seen for food stimuli compared to generally emotion eliciting stimuli. Adolescents with AN show reduced processing of affective stimuli and enhanced activation of regions involved in "bottom up" reward processing and "top down" control as well as the insula with regard to food stimuli with a focus on brain regions which underlie changes during adolescent development. In adults less clear and less specific activation differences were present, pointing towards a high impact that regions undergoing maturation might have on AN symptoms. PMID- 29579063 TI - In silico identification of microRNAs predicted to regulate N myristoyltransferase and Methionine Aminopeptidase 2 functions in cancer and infectious diseases. AB - Protein myristoylation is a key protein modification carried out by N Myristoyltransferase (NMT) after Methionine aminopeptidase 2 (MetAP2) removes methionine from the amino-terminus of the target protein. Protein myristoylation by NMT augments several signaling pathways involved in a myriad of cellular processes, including developmental pathways and pathways that when dysregulated lead to cancer or immune dysfunction. The emerging evidence pointing to NMT mediated myristoylation as a major cellular regulator underscores the importance of understanding the framework of this type of signaling event. Various studies have investigated the role that myristoylation plays in signaling dysfunction by examining differential gene or protein expression between normal and diseased states, such as cancers or following HIV-1 infection, however no study exists that addresses the role of microRNAs (miRNAs) in the regulation of myristoylation. By performing a large scale bioinformatics and functional analysis of the miRNAs that target key genes involved in myristoylation (NMT1, NMT2, MetAP2), we have narrowed down a list of promising candidates for further analysis. Our condensed panel of miRNAs identifies 35 miRNAs linked to cancer, 21 miRNAs linked to developmental and immune signaling pathways, and 14 miRNAs linked to infectious disease (primarily HIV). The miRNAs panel that was analyzed revealed several NMT-targeting mRNAs (messenger RNA) that are implicated in diseases associated with NMT signaling alteration, providing a link between the realms of miRNA and myristoylation signaling. These findings verify miRNA as an additional facet of myristoylation signaling that must be considered to gain a full perspective. This study provides the groundwork for future studies concerning NMT-transcript-binding miRNAs, and will potentially lead to the development of new diagnostic/prognostic biomarkers and therapeutic targets for several important diseases. PMID- 29579065 TI - The effect of estrogenic compounds on psychosis-like behaviour in female rats. AB - 17beta-estradiol treatment has shown benefit against schizophrenia symptoms, however long-term use may be associated with negative side-effects. Selective estrogen receptor modulators, such as raloxifene and tamoxifen, have been proposed as suitable alternatives to 17beta-estradiol. An isomer of 17beta estradiol, 17alpha-estradiol, is considered less carcinogenic, and non-feminising in males, however little is known about its potential as a treatment for schizophrenia. Moreover, the mechanism underlying the therapeutic action of estrogens remains unclear. We aimed to investigate the ability of these estrogenic compounds to attenuate psychosis-like behaviour in rats. We used two acute pharmacologically-induced assays of psychosis-like behaviour: psychotomimetic drug-induced hyperlocomotion and disruption of prepulse inhibition (PPI). Female Long Evans rats were either intact, ovariectomised (OVX), or OVX and chronically treated with 17beta-estradiol, 17alpha-estradiol, raloxifene or tamoxifen. Only 17beta-estradiol treatment attenuated locomotor hyperactivity induced by the indirect dopamine receptor agonist, methamphetamine. 17beta-estradiol- and tamoxifen-treated rats showed attenuated methamphetamine- and apomorphine (dopamine D1/D2 receptor agonist)-induced disruption of PPI. Raloxifene-treated rats showed attenuated apomorphine-induced PPI disruption only. Baseline PPI was significantly reduced following OVX, and this deficit was reversed by all estrogenic compounds. Further, PPI in OVX rats was increased following administration of apomorphine. This study confirms a protective effect of 17beta-estradiol in two established animal models of psychosis, while tamoxifen showed beneficial effects against PPI disruption. In contrast, 17alpha estradiol and raloxifene showed little effect on dopamine receptor-mediated psychosis-like behaviours. This study highlights the utility of some estrogenic compounds to attenuate psychosis-like behaviour in rats, supporting the notion that estrogens have therapeutic potential for psychotic disorders. PMID- 29579066 TI - Assessment of viral methylation levels for high risk HPV types by newly designed consensus primers PCR and pyrosequencing. AB - BACKGROUND: Measuring viral DNA methylation in human papillomavirus (HPV) infected women showed promise for accurate detection of high-grade cervical lesions and cancer. Methylation status has been widely investigated for HPV16, sporadically for other HPV types. METHODS: Objective of this methodological study was to set up molecular methods to test the methylation levels in the twelve oncogenic HPV types by pyrosequencing, minimizing the number of HPV type-specific PCR protocols. Target CpGs were selected on the HPV L1 (two regions, L1 I and L1 II) and L2 genes. Study samples included DNA stored at Turin, Italy, purified by cervical cells collected in Standard Transport Medium or PreservCyt from women who participated in two studies (N = 126 and 140) nested within the regional organized screening programme. PCR consensus primers were designed by PyroMark Assay Design software to be suitable for amplification of many different oncogenic HPV types. RESULTS: Generation of consensus primers was successful for L1 I and II regions, unsuccessful for L2 region, for which HPV type-specific primers remained necessary. The difference between replicated tests on the same sample was <=4% in 88%, 77% and 91% of cases when targeting the L1 I, L1 II and L2 regions, respectively. The corresponding intra-class correlation coefficients (ICC) were 0.94, 0.87 and 0.97 respectively. When comparing methylation measures based on consensus and type-specific primers, ICC was 0.97 for the L1 I region and 0.99 the for L1 II region. CONCLUSIONS: The proposed protocols, applying consensus primers suitable to amplify the oncogenic HPV types and minimize the number of PCR reactions, represent a promising tool to quantify viral methylation in women positive for any high risk HPV type. IMPACT: Potential application of these methylation protocols in screening settings can be explored to identify women with high probability of progression to high grade lesions. PMID- 29579067 TI - Audio-based performance evaluation of squash players. AB - In competitive sports it is often very hard to quantify the performance. A player to score or overtake may depend on only millesimal of seconds or millimeters. In racquet sports like tennis, table tennis and squash many events will occur in a short time duration, whose recording and analysis can help reveal the differences in performance. In this paper we show that it is possible to architect a framework that utilizes the characteristic sound patterns to precisely classify the types of and localize the positions of these events. From these basic information the shot types and the ball speed along the trajectories can be estimated. Comparing these estimates with the optimal speed and target the precision of the shot can be defined. The detailed shot statistics and precision information significantly enriches and improves data available today. Feeding them back to the players and the coaches facilitates to describe playing performance objectively and to improve strategy skills. The framework is implemented, its hardware and software components are installed and tested in a squash court. PMID- 29579068 TI - Rapid activity-dependent modulation of the intrinsic excitability through up regulation of KCNQ/Kv7 channel function in neonatal spinal motoneurons. AB - Activity-dependent changes in the properties of the motor system underlie the necessary adjustments in its responsiveness on the basis of the environmental and developmental demands of the organism. Although plastic changes in the properties of the spinal cord have historically been neglected because of the archaic belief that the spinal cord is constituted by a hardwired network that simply relays information to muscles, plenty of evidence has been accumulated showing that synapses impinging on spinal motoneurons undergo short- and long-term plasticity. In the brain, brief changes in the activity level of the network have been shown to be paralleled by changes in the intrinsic excitability of the neurons and are suggested to either reinforce or stabilize the changes at the synaptic level. However, rapid activity-dependent changes in the intrinsic properties of spinal motoneurons have never been reported. In this study, we show that in neonatal mice the intrinsic excitability of spinal motoneurons is depressed after relatively brief but sustained changes in the spinal cord network activity. Using electrophysiological techniques together with specific pharmacological blockers of KCNQ/Kv7 channels, we demonstrate their involvement in the reduction of the intrinsic excitability of spinal motoneurons. This action results from an increased M-current, the product of the activation of KCNQ/Kv7 channels, which leads to a hyperpolarization of the resting membrane potential and a decrease in the input resistance of spinal motoneurons. Computer simulations showed that specific up-regulations in KCNQ/Kv7 channels functions lead to a modulation of the intrinsic excitability of spinal motoneurons as observed experimentally. These results indicate that KCNQ/Kv7 channels play a fundamental role in the activity-dependent modulation of the excitability of spinal motoneurons. PMID- 29579070 TI - Encountering epidemic effects of leaf spot disease (Alternaria brassicae) on Aloe vera by fungal biocontrol agents in agrifields-An ecofriendly approach. AB - Aloe vera (L.) Burm.f. is a highly important and extensively cultivated medicinal plant and that is also extensively used in the cosmetic industry. It has been frequently reported to suffer from Alternaria leaf spot disease in various parts of the world. Various fungicides used to combat this disease, have deleterious effects on the environment and on pharmacologically important constituents of Aloe vera. To avoid the harmful effects of fungicides an ecofriendly approach has been adopted here. A weekly survey was conducted during 2013-2015 in and around North 24 Parganas (West Bengal) to obtain the percentage of disease index (PDI). For biological control of the disease, screening of the antagonistic efficacy of biocontrol agents was carried out through the in vitro dual-culture-plate method and scanning electron microscopy (SEM) was used to study the mechanism. The in vitro effects of fungicides on the radial growth of the pathogen were evaluated through the poison food method and were compared with potent antagonistic fungi. Field application of potent antagonistic fungi was conducted through the dip-and spray method. The results showed that, the PDI peaked during the hot and humid conditions of May to September (76.57%-98.57%) but decreased during the winter, December-January (35.71-46.66%). Trichoderma asperellum exerted the greatest inhibition of the radial growth of A. brassicae acting through non volatile (70.39%) and volatile metabolites (72.17%). A SEM study confirmed the hyperparasitic nature of T. asperellum through hyphal coiling-T. asperellum was similar to 2% blitox-50 (73.92%) and better than 2% bavistin (59.77%) (in vitro). In agricultural field trials (2013-15), Trichoderma application restricted the disease to the smallest area (PDI 24.00-29.33%) in comparison to untreated plots (73.33%). In conclusion, saplings treated with the dip method (108 spores / mL) and sprayed 4 times with a spore suspension of biocontrol agents such as T. asperellum, T. viride and T. harzianum, standardized at a rate of 2.5 L / plot (36 sq ft) (108 spores/ mL) are suggested for the ecofriendly management of this epidemic leaf spot disease of Aloe vera in agricultural fields. PMID- 29579069 TI - Molecular and morphological data of the freshwater fish Glandulocauda melanopleura (Characiformes: Characidae) provide evidences of river captures and local differentiation in the Brazilian Atlantic Forest. AB - The current distribution of freshwater fishes across multiple basins along Eastern Brazil can be associated to two main events: river captures or temporary paleoconnections. Apparently, river captures had a more significant role on distribution and structuring of species from upland areas, such as Glandulocauda melanopleura. Populations of this species are found in contiguous drainages in presently isolated upper parts of Rio Tiete and the coastal basins of Guaratuba, Itatinga, Itanhaem, and Ribeira de Iguape, in the Atlantic Forest domain. The allopatric and disjoint distribution of G. melanopleura associated with variation of morphological characters detected among geographically isolated populations stimulated this study. Thus, an integrative approach was undertaken, including morphological and molecular data, to better understand the evolutionary history of the species and the area where it occurs. Molecular analyses based on two mitochondrial markers revealed a strong genetic structure within G. melanopleura, that allowed recognition of two lineages, one distributed in both the upper Tiete and Itanhaem and the other in the Guaratuba. Overall, morphological data revealed some intraspecific overlapping variation, indicating that all samples are conspecific. Phylogenetic and phylogeographic analyses allied to divergence times and geomorphological information indicate that the current distribution of G. melanopleura is a result of relatively recent river captures involving the Tiete and some other coastal drainages. Although of recent origin, they occurred long enough to completely isolate these populations, since there are no haplotypes sharing between them. The conservation status of this species is also discussed, and our results corroborate the need to understand population structure for conservation planning. PMID- 29579071 TI - HMMER Cut-off Threshold Tool (HMMERCTTER): Supervised classification of superfamily protein sequences with a reliable cut-off threshold. AB - BACKGROUND: Protein superfamilies can be divided into subfamilies of proteins with different functional characteristics. Their sequences can be classified hierarchically, which is part of sequence function assignation. Typically, there are no clear subfamily hallmarks that would allow pattern-based function assignation by which this task is mostly achieved based on the similarity principle. This is hampered by the lack of a score cut-off that is both sensitive and specific. RESULTS: HMMER Cut-off Threshold Tool (HMMERCTTER) adds a reliable cut-off threshold to the popular HMMER. Using a high quality superfamily phylogeny, it clusters a set of training sequences such that the cluster-specific HMMER profiles show cluster or subfamily member detection with 100% precision and recall (P&R), thereby generating a specific threshold as inclusion cut-off. Profiles and thresholds are then used as classifiers to screen a target dataset. Iterative inclusion of novel sequences to groups and the corresponding HMMER profiles results in high sensitivity while specificity is maintained by imposing 100% P&R self detection. In three presented case studies of protein superfamilies, classification of large datasets with 100% precision was achieved with over 95% recall. Limits and caveats are presented and explained. CONCLUSIONS: HMMERCTTER is a promising protein superfamily sequence classifier provided high quality training datasets are used. It provides a decision support system that aids in the difficult task of sequence function assignation in the twilight zone of sequence similarity. All relevant data and source codes are available from the Github repository at the following URL: https://github.com/BBCMdP/HMMERCTTER. PMID- 29579072 TI - Judgement analysis of case severity and future risk of disability regarding chronic low back pain by general practitioners in Ireland. AB - Chronic low back pain is a major healthcare burden that has wide ranging effects on the individual, their family, society and the workplace. However, appropriate management and treatment is often difficult, as a majority of cases are non specific in terms of underlying pathology. As a result, there are extensive differences in both individual patient preferences for treatment and treatment decisions amongst general practitioners. The current study examined the clinical judgements of GPs in Ireland, regarding fictional patients' case severity and future risk of disability, through judgement analysis. Judgement analysis (JA) is an idiographic regression modelling technique that has been utilised in extant healthcare research for the purpose of allocating weighting to judgement criteria, or cues, observed by professionals in their clinical decision-making. The primary aim of the study was to model two critical information utilisation tasks performed by GPs with regard to CLBP-in combining information cues to form a judgement about current case severity and a judgement about the same patient's risk of future disability. It was hypothesised that the judgement weighting would differ across the two judgements and that judgements regarding future risk of disability would be less consistent among GPs than judgements about case severity. Results from the regression-based judgement analysis and subsequent follow-up statistical analysis provided support for both study hypotheses. Study findings are discussed in light of theory and research on judgement, clinical decision-making and chronic low back pain. PMID- 29579073 TI - The impact of methadone maintenance therapy on access to regular physician care regarding hepatitis C among people who inject drugs. AB - BACKGROUND & AIMS: People who inject drugs (PWID) living with hepatitis C virus (HCV) infection often experience barriers to accessing HCV treatment and care. New, safer and more effective direct-acting antiviral-based therapies offer an opportunity to scale-up HCV-related services. Methadone maintenance therapy (MMT) programs have been shown to be effective in linking PWID to health and support services, largely in the context of HIV. The objective of the study was to examine the relationship between being enrolled in MMT and having access to regular physician care regarding HCV among HCV antibody-positive PWID in Vancouver, Canada. DESIGN: Three prospective cohort studies of people who use illicit drugs. SETTING: Vancouver, Canada. PARTICIPANTS: We restricted the study sample to 1627 HCV-positive PWID between September 2005 and May 2015. MEASUREMENTS: A marginal structural model using inverse probability of treatment weights was used to estimate the longitudinal relationship between being enrolled in MMT and having a regular HCV physician and/or specialist. FINDINGS: In total, 1357 (83.4%) reported having access to regular physician care regarding HCV at least once during the study period. A marginal structural model estimated a 2.12 (95% confidence interval [CI]: 1.77-2.20) greater odds of having a regular HCV physician among participants enrolled in MMT compared to those not enrolled. CONCLUSIONS: HCV-positive PWID who enrolled in MMT were more likely to report access to regular physician care regarding HCV compared to those not enrolled in MMT. These findings demonstrate that opioid agonist treatment may be helpful in linking PWID to HCV care, and highlight the need to better engage people who use drugs in substance use care, when appropriate. PMID- 29579074 TI - Prevalence and determinants of self-medication practice among selected households in Addis Ababa community. AB - BACKGROUND AND AIM: Self-medication (SM) is one part of self-care which is known to contribute to primary health care. If practiced appropriately, it has major benefits for the consumers such as self-reliance and decreased expense. However, inappropriate practice can have potential dangers such as incorrect self diagnosis, dangerous drug-drug interactions, incorrect manner of administration, incorrect dosage, incorrect choice of therapy, masking of a severe disease, and/or risk of dependence and abuse. The main objective of this study was to assess the prevalence and determinants of the self-medication practice (SMP) in Addis Ababa. METHODOLOGY: A community based cross-sectional study was conducted among selected households in Addis Ababa from April 2016 to May 2016, with a recall period of two months before its conduction. Trained data collectors were employed to collect the data from the 604 sampled participants using pre-tested and validated questionnaires. RESULT: Among the 604 participants involved in this study, 422 (69.9%) were female and 182 (30.1%) were male and there was a mean age of 41.04 (+/- 13.45) years. The prevalence of SM in this study was 75.5%. The three most frequently reported ailments were headache 117 (25.7%), abdominal pain 59 (12.9%) and cough 54 (11.8%). The two main reasons for SM were mildness of illness 216 (47.4%) and previous knowledge about the drug 106 (23.2%). The two most frequently consumed medications were paracetamol 92 (20.2%) and traditional remedies 73 (16.0%), while drug retail outlets 319 (83.3%) were the main source of drugs. The two most frequently reported source of drug information were health professionals 174 (45.4%) and experience from previous treatment 82 (21.4%). Moreover, there were statistically significant differences among respondents who reported practicing SM based on income and knowledge about appropriate SMP. CONCLUSION AND RECOMMENDATION: Self-medication was practiced with a range of drugs from the conventional paracetamol and NSAIDs to antimicrobials. Being that the practice of SM is inevitable, health authorities and professionals are highly demanded to educate the public not only on the advantages and disadvantages of SM but on its proper use. PMID- 29579075 TI - Effects of pharmacologic sclerostin inhibition or testosterone administration on soleus muscle atrophy in rodents after spinal cord injury. AB - Sclerostin is a circulating osteocyte-derived glycoprotein that negatively regulates Wnt-signaling after binding the LRP5/LRP6 co-receptors. Pharmacologic sclerostin inhibition produces bone anabolic effects after spinal cord injury (SCI), however, the effects of sclerostin-antibody (Scl-Ab) on muscle morphology remain unknown. In comparison, androgen administration produces bone antiresorptive effects after SCI and some, but not all, studies have reported that testosterone treatment ameliorates skeletal muscle atrophy in this context. Our purposes were to determine whether Scl-Ab prevents hindlimb muscle loss after SCI and compare the effects of Scl-Ab to testosterone enanthate (TE), an agent with known myotrophic effects. Male Sprague-Dawley rats aged 5 months received: (A) SHAM surgery (T8 laminectomy), (B) moderate-severe contusion SCI, (C) SCI+TE (7.0 mg/wk, im), or (D) SCI+Scl-Ab (25 mg/kg, twice weekly, sc). Twenty-one days post-injury, SCI animals exhibited a 31% lower soleus mass in comparison to SHAM, accompanied by >50% lower soleus muscle fiber cross-sectional area (fCSA) (p<0.01 for all fiber types). Scl-Ab did not prevent soleus atrophy, consistent with the relatively low circulating sclerostin concentrations and with the 91-99% lower LRP5/LRP6 gene expressions in soleus versus tibia (p<0.001), a tissue with known anabolic responsiveness to Scl-Ab. In comparison, TE partially prevented soleus atrophy and increased levator ani/bulbocavernosus (LABC) mass by 30-40% (p<0.001 vs all groups). The differing myotrophic responsiveness coincided with a 3-fold higher androgen receptor gene expression in LABC versus soleus (p<0.01). This study provides the first direct evidence that Scl-Ab does not prevent soleus muscle atrophy in rodents after SCI and suggests that variable myotrophic responses in rodent muscles after androgen administration are influenced by androgen receptor expression. PMID- 29579076 TI - Genetic structure of wild pea (Pisum sativum subsp. elatius) populations in the northern part of the Fertile Crescent reflects moderate cross-pollination and strong effect of geographic but not environmental distance. AB - Knowledge of current genetic diversity and mating systems of crop wild relatives (CWR) in the Fertile Crescent is important in crop genetic improvement, because western agriculture began in the area after the cold-dry period known as Younger Dryas about 12,000 years ago and these species are also wild genepools of the world's most important food crops. Wild pea (Pisum sativum subsp. elatius) is an important source of genetic diversity for further pea crop improvement harbouring traits useful in climate change context. The genetic structure was assessed on 187 individuals of Pisum sativum subsp. elatius from fourteen populations collected in the northern part of the Fertile Crescent using 18,397 genome wide single nucleotide polymorphism DARTseq markers. AMOVA showed that 63% of the allelic variation was distributed between populations and 19% between individuals within populations. Four populations were found to contain admixed individuals. The observed heterozygosity ranged between 0.99 to 6.26% with estimated self pollination rate between 47 to 90%. Genetic distances of wild pea populations were correlated with geographic but not environmental (climatic) distances and support a mixed mating system with predominant self-pollination. Niche modelling with future climatic projections showed a local decline in habitats suitable for wild pea, making a strong case for further collection and ex situ conservation. PMID- 29579077 TI - Simulated tri-trophic networks reveal complex relationships between species diversity and interaction diversity. AB - Most of earth's biodiversity is comprised of interactions among species, yet it is unclear what causes variation in interaction diversity across space and time. We define interaction diversity as the richness and relative abundance of interactions linking species together at scales from localized, measurable webs to entire ecosystems. Large-scale patterns suggest that two basic components of interaction diversity differ substantially and predictably between different ecosystems: overall taxonomic diversity and host specificity of consumers. Understanding how these factors influence interaction diversity, and quantifying the causes and effects of variation in interaction diversity are important goals for community ecology. While previous studies have examined the effects of sampling bias and consumer specialization on determining patterns of ecological networks, these studies were restricted to two trophic levels and did not incorporate realistic variation in species diversity and consumer diet breadth. Here, we developed a food web model to generate tri-trophic ecological networks, and evaluated specific hypotheses about how the diversity of trophic interactions and species diversity are related under different scenarios of species richness, taxonomic abundance, and consumer diet breadth. We investigated the accumulation of species and interactions and found that interactions accumulate more quickly; thus, the accumulation of novel interactions may require less sampling effort than sampling species in order to get reliable estimates of either type of diversity. Mean consumer diet breadth influenced the correlation between species and interaction diversity significantly more than variation in both species richness and taxonomic abundance. However, this effect of diet breadth on interaction diversity is conditional on the number of observed interactions included in the models. The results presented here will help develop realistic predictions of the relationships between consumer diet breadth, interaction diversity, and species diversity within multi-trophic communities, which is critical for the conservation of biodiversity in this period of accelerated global change. PMID- 29579078 TI - A novel high-throughput immunofluorescence analysis method for quantifying dystrophin intensity in entire transverse sections of Duchenne muscular dystrophy muscle biopsy samples. AB - Clinical trials using strategies aimed at inducing dystrophin expression in Duchenne muscular dystrophy (DMD) are underway or at advanced planning stage, including splice switching antisense oligonucleotides (AON), drugs to induce read through of nonsense mutations and viral mediated gene therapy. In all these strategies, different dystrophin proteins, often internally deleted, are produced, similar to those found in patients with the milder DMD allelic variant, Becker muscular dystrophy (BMD). The primary biological endpoint of these trials is to induce functional dystrophin expression. A reliable and reproducible method for quantification of dystrophin protein expression at the sarcolemma is crucial to monitor the biochemical outcome of such treatments. We developed a new high throughput semi quantitative fluorescent immunofluorescence method for quantifying dystrophin expression in transverse sections of skeletal muscle. This technique is completely operator independent as it based on an automated scanning system and an image processing script developed with Definiens software. We applied this new acquisition-analysis method to quantify dystrophin and sarcolemma-related proteins using paediatric control muscles from cases without a neuromuscular disorder as well as DMD and BMD samples. The image analysis script was instructed to recognize myofibres immunostained for spectrin or laminin while dystrophin was quantified in each identified myofibre (from 2,000 to over 20,000 fibres, depending on the size of the biopsy). We were able to simultaneously extrapolate relevant parameters such as mean sarcolemmal dystrophin, mean spectrin and laminin intensity, fibre area and diameter. In this way we assessed dystrophin production in each muscle fibre in samples of DMD, BMD and controls. This new method allows the unbiased quantification of dystrophin in every myofibre within a transverse muscle section and will be of help for translational research projects as a biological outcome in clinical trials in DMD and BMD. PMID- 29579079 TI - Enhanced differentiation of human pluripotent stem cells into cardiomyocytes by bacteria-mediated transcription factors delivery. AB - Virus-mediated expression of defined transcription factor (TF) genes can effectively induce cellular reprogramming. However, sustained expression of the TFs often hinders pluripotent stem cell (PSC) differentiation into specific cell types, as each TF exerts its effect on PSCs for a defined period of time during differentiation. Here, we applied a bacterial type III secretion system (T3SS) based protein delivery tool to directly translocate TFs in the form of protein into human PSCs. This transient protein delivery technique showed high delivery efficiency for hPSCs, and it avoids potential genetic alterations caused by the introduction of transgenes. In an established cardiomyocyte de novo differentiation procedure, five transcriptional factors, namely GATA4, MEF2C, TBX5, ESRRG and MESP1 (abbreviated as GMTEM), were translocated at various time points. By detecting the expression of cardiac marker genes (Nkx2.5 and cTnT), we found that GMTEM proteins delivered on mesoderm stage of the cardiomyocytes lineage differentiation significantly enhanced both the human ESC and iPSC differentiation into cardiomyocytes, while earlier or later delivery diminished the enhancing effect. Furthermore, all of the five factors were required to enhance the cardiac differentiation. This work provides a virus-free strategy of transient transcription factors delivery for directing human stem cell fate without jeopardizing genome integrity, thus safe for biomedical applications. PMID- 29579080 TI - Variation in the microbiome of the urogenital tract of Chlamydia-free female koalas (Phascolarctos cinereus) with and without 'wet bottom'. AB - Koalas (Phascolarctos cinereus) are iconic Australian marsupials currently threatened by several processes, including infectious diseases and ecological disruption. Infection with Chlamydia pecorum, is considered a key driver of population decline. The clinical sign of 'wet bottom', a staining of the rump associated with urinary incontinence, is often caused by chlamydial urinary tract infections. However, wet bottom has been recorded in koalas free of C. pecorum, suggesting other causative agents in those individuals. We used 16S rRNA diversity profiling to investigate the microbiome of the urogenital tract of ten female koalas in order to identify potential causative agents of wet bottom, other than C. pecorum. Five urogenital samples were processed from koalas presenting with wet bottom and five were clinically normal. All koalas were negative for C. pecorum infection. We detected thirteen phyla across the ten samples, with Firmicutes occurring at the highest relative abundance (77.6%). The order Lactobacillales, within the Firmicutes, comprised 70.3% of the reads from all samples. After normalising reads using DESeq2 and testing for significant differences (P < 0.05), there were 25 operational taxonomic units (OTUs) more commonly found in one group over the other. The families Aerococcaceae and Tissierellaceae both had four significantly differentially abundant OTUs. These four Tissierellaceae OTUs were all significantly more abundant in koalas with wet bottom. This study provides the foundation for future investigations of causes of koala wet bottom, other than C. pecorum infection. This is of clinical relevance as wet bottom is often assumed to be caused by C. pecorum and treated accordingly. Our research highlights that other organisms may be causing wet bottom, and these potential aetiological agents need to be further investigated to fully address the problems this species faces. PMID- 29579081 TI - Genetics in TNF-TNFR pathway: A complex network causing spondyloarthritis and conditioning response to anti-TNFalpha therapy. AB - OBJECTIVES: We investigated whether polymorphisms (SNPs) in the promoter region of TNFA, or in the autoinflammatory TNFRSF1A and MEFV genes, concur with HLA-B27 in enhancing the risk of Spondyloarthritis (SpA) and/or in predicting the response to anti-TNFalpha treatment. METHODS: 373 controls and 137 SpA (82 with Psoriatic Arthritis-PsA and 55 with Ankylosing Spondylitis- AS; 98/137 under TNFalpha inhibitor therapy) from the Veneto Region (Italy) were studied. TNFA polymorphisms (-1031T>C;-857C>T;-376G>A;-308G>A;-238G>A) and HLA-B27 were assayed by RT-PCR. Direct sequencing of MEFV (exons 2,3,5 and 10) and TNFRSF1A (exons 2,3,4 and 6) genes were performed. RESULTS: HLA-B27 was associated with AS (chi2 = 120.1; p = 0.000). Only the TNFA -1031T>C was singly associated with SpA, and the haplotype C/G, resulting from -1031T>C/-308G>A combination, was significantly associated with a reduced risk of SpA (OR: 0.67, CI: 0.46-0.97; p = 0.035). Two SNPs were identified in TNFRSF1A, the R92Q (Minor allele frequency-MAF = 0.034) and c.625+10A>G (MAF = 0.479). None of them was associated with SpA (p>0.05). The TNFRSF1A c.625+10 G allele was associated with late response to anti-TNFalpha therapy (p = 0.031). Twenty-one SNPs were identified in MEFV gene, 10 with a known potential functional significance. Variant alleles were extremely rare in our population (MAF<0.025) except for R202Q (MAF = 0.27). None was associated with SpA diagnosis (p>0.05). CONCLUSION: TNFRSF1A and MEFV gene SNPs are not associated with SpA in the North-East of Italy. AS risk appears to depend not only on HLA-B27, but also on the protective TNFA haplotype -1031C/-308G. The TNFRSF1A c.625+10A>G impacts on the response to anti-TNFalpha therapy. PMID- 29579082 TI - PrePex circumcision surveillance: Adverse events and analgesia for device removal. AB - BACKGROUND: The PrePex medical male circumcision (MMC) device is relatively easy to place and remove with some training. PrePex has been evaluated in several countries to assess feasibility and acceptability. However, several studies have reported pain associated with removal. OBJECTIVE: To assess safety of PrePex and whether analgesia administered prior to removal reduces pain experienced by participants. METHODS: A multi-site non-randomized, prospective cohort study in which adult (18-45 years old) males requesting PrePex device male circumcision, were enrolled in six South African clinics from July 2014 to March 2015. Participants were routinely provided with analgesia shortly after the surveillance commenced following a protocol review. Analgesia regimen for device removal depended on medication availability at clinics. RESULTS: Of 1023 enrolled participants who had PrePex placed, 98% (1004) had the device removed at a study clinic. Their median age was 25 (IQR: 21-30) years. HIV sero-positivity was 3.6% (37/1023). Nurses placed and removed half of all devices. Adverse events were experienced by 2.4% (25/1023) of participants; 15 required surgical intervention: device displacement (5/14), early removals (3/14), self-removals (5/14) and insufficient skin removed (2/14). Majority (792: 79%) of participants received analgesia. Most received either paracetamol-codeine (33%), lidocaine (29%) or EMLA and Oral Combination (28%). A lower proportion of participants who received any analgesia (except for lidocaine) prior to PrePex removal experienced severe pain compared to those who received no analgesia (16.6% vs. 29%: p = 0.0001). CONCLUSION: Reported adverse events during this PrePex active surveillance were similar to previous reports and to those of surgical circumcision. Pain medication provided prior to removal is effective at decreasing severe pain during PrePex device removal. PMID- 29579083 TI - Obesity and emergency care in the French CONSTANCES cohort. AB - CONTEXT: Obese patients are raising specific questions in emergency care such as equipment issues or urgent procedures. Even though obesity prevalence and subsequent health expenditure are increasing worldwide, there is scarce literature about their specific resource utilization of Emergency Departments (ED). These few studies do not take into account both socio-economic situation and comorbidities which are well-known factors influencing healthcare use. Our objective was to assess the emergency care resource utilization of obese individuals (Body Mass Index (BMI) >= 30kg.m-2) compared to normal-weight individuals taking into account comorbidities and social-economic situations. METHODS: The French CONSTANCES epidemiologic cohort is a randomly selected sample of French adults. Participants data are linked to the National Health Insurance Database collecting all medical acts. The rate of ED visits of obese (and each obesity class) and normal-weight participants were compared considering confounding factors (comorbidities, various socio-economic data). The primary endpoint was to have visited the ED between 2010 and 2013. Sex-separated analysis and multivariate logistic regression models were performed and adjusted odds ratios [OR] (95% Confidence Intervals [CI]) were calculated. RESULTS: We included 21,035 normal-weight and 5,003 obese participants. Obese participants visited the ED more often than normal-weight participants (men: 30.5% vs. 26.7%; women: 30.3% vs. 24.4%, P<0.001). Obese participants presented more comorbidities and a lower socio-economic situation than normal-weight participants. After adjustment, obese participants had a higher risk of visiting ED (men: OR = 1.18; 95% CI: 1.04-1.33; and women: OR = 1.36; 95% CI: 1.22-1.52), with a higher risk for class III participants (BMI >= 40 kg.m-2) (men: OR = 2.18; CI 95%: 1.32-3.63; and women: OR = 1.85; 95% CI: 1.38-2.49). CONCLUSION: Obese individuals have a higher level of emergency care resource utilization than normal-weight individuals and it increases with severe obesity. Further studies are needed to better understand their healthcare pathways leading to EDs. PMID- 29579085 TI - A performance-based evaluation of chemically similar (carbonate) tempers from Late Prehistoric (AD 1200-1700) Ohio: Implications for human selection and production of ceramic technology. AB - PURPOSE: This study was designed to assess the mechanical properties of two calcium carbonate tempers, limestone and burnt shell. These tempers have been previously compared, in separate studies, to silicate-based grit or sand temper and, relative to the latter, are assumed to possess similar mechanical properties. However, their simultaneous use at the Morrison Village site begs the question: do these two calcium carbonate tempers indeed possess similar mechanical properties? In order to assess their performance characteristics, a side-by-side controlled experimental test was conducted to determine the degree of similarity in providing increased vessel strength and toughness. METHODS: Standardized ceramic test samples were systematically prepared via a set, explicit protocol. An Instron Series IX universal testing machine configured with a four-point flexural test jig was used to perform a flexural strength test of the test samples. The Instron load and deflection data were used to calculate three values related to mechanical performance: peak load, modulus of rupture, and modulus of elasticity. RESULTS: All four comparative tests clearly show substantial differences in peak load, modulus of rupture, and modulus of elasticity. These differences are statistically significant for each performance attribute in every iteration of the experiment and as indicated by Mann-Whitney U Tests. CONCLUSIONS: These results do not support the hypothesis that limestone and burnt shell offer the same performance characteristics. These results have implications for our understanding of prehistoric human selection of temper and the evolution of ceramic technology. Although both carbonate-based tempers are currently thought to offer the same benefits during the initial phase of pottery production, their contrasting post firing properties would have provided distinct benefits in different contexts. Future assessments of the Morrison Village ceramic assemblage should focus on residue analysis, or other functional indicators, to support or falsify this hypothesis. PMID- 29579084 TI - Reliability and usefulness of spirometry performed during admission for COPD exacerbation. AB - OBJECTIVES: Although not currently recommended, spirometry during hospitalization due to exacerbation of chronic obstructive pulmonary disease (COPD) is an opportunity to enhance the diagnosis of this disease. The aim of the present study was to assess the usefulness and reliability of spirometry before hospital discharge, comparing it to measurements obtained during clinical stability. METHODS: This prospective longitudinal observational study compares spirometry results before and 8 weeks after discharge in consecutive patients admitted for COPD exacerbation. Concordance between results was assessed by the Kappa index, intraclass correlation coefficient, and Bland-Altman graphs. RESULTS: From an initial population of 179 COPD patients, 100 completed the study (mean age 67.8 years, 83% men, 35% active smokers, FEV1 at clinical stability 40.3%). Forty-nine patients could not complete the study because they did not reach clinical stability. In three patients with obstructive spirometry during admission, the results were normal at follow-up. In the remaining patients, the COPD diagnosis was confirmed at stability with acceptable concordance. In 27 cases, spirometry improved more than 200 mL.No variables were found to be associated with this improvement or to explain it. CONCLUSIONS: This study provides information on the role of spirometry prior to hospital discharge in patients admitted for COPD exacerbation, demonstrating that it is a valid and reproducible method, representing an opportunity toimprove COPD diagnosis. PMID- 29579086 TI - Tuberculosis during pregnancy in the United States: Racial/ethnic disparities in pregnancy complications and in-hospital death. AB - BACKGROUND: Despite decades of efforts to eliminate tuberculosis (TB) in the United States (US), TB still contributes to adverse ill health, especially among racial/ethnic minorities. According to the Centers for Disease Control and Prevention, in 2016, about 87% of the TB cases reported in the US were among racial and ethnic minorities. The objective of this study is to explore the risks for pregnancy complications and in-hospital death among mothers diagnosed with TB across racial/ethnic groups in the US. METHODS: This retrospective cohort study utilized National Inpatient Sample data for all inpatient hospital discharges in the US. We analyzed pregnancy-related hospitalizations and births in the US from January 1, 2002 through December 31, 2014 (n = 57,393,459). Multivariable logistic regression was applied to generate odds ratios for the association between TB status and the primary study outcomes (i.e., pregnancy complications and in-hospital death) across racial/ethnic categories. RESULTS: The prevalence of TB was 7.1 per 100,000 pregnancy-related hospitalizations. The overall prevalence of pregnancy complications was 80% greater among TB-infected mothers than their uninfected counterparts. Severe pre-eclampsia, eclampsia, placenta previa, post-partum hemorrhage, sepsis and anemia occurred with greater frequency among mothers with a TB diagnosis than those without TB, irrespective of race/ethnicity. The rate of in-hospital death among TB patients was 37 times greater among TB-infected than in non-TB infected mothers (468.8 per 100,000 versus 12.6 per 100,000). A 3-fold increased risk of in-hospital death was observed among black TB-negative mothers compared to their white counterparts. No racial/ethnic disparities in maternal morbidity or in-hospital death were found among mothers with TB disease. CONCLUSION: TB continues to be an important cause of morbidity and mortality among pregnant women in the US. Resources to address TB disease should also target pregnant women, especially racial/ethnic minorities who bear the greatest burden of the disease. PMID- 29579088 TI - The geography of references in elite articles: Which countries contribute to the archives of knowledge? AB - This study asks the question on which national "shoulders" the world's top-level research stands. Traditionally, the number of citations to national papers has been the evaluative measures of national scientific standings. We raise a different question: instead of analyzing the citations to a countries' articles (the forward view), we examine references to prior publications from specific countries cited in the most elite publications (the backward-citing-view). "Elite publications" are operationalized as the top-1% most-highly cited articles. Using the articles published from 2004 to 2013, we examine the research referenced in these works. Our results confirm the well-known fact that China has emerged to become a major player in science. However, China still belongs to the low contributors when countries are ranked as contributors to the cited references in top-1% articles. Using this perspective, the results do not support a decreasing trend for the USA; in fact, the USA exceeds expectations (compared to its publication share) in terms of references in the top-1% articles. Switzerland, Sweden, and the Netherlands also appear at the top of the list. However, the results for Germany are lower than statistically expected. PMID- 29579087 TI - Class I HDAC inhibition is a novel pathway for regulating astrocytic apoE secretion. AB - Despite the important role of apolipoprotein E (apoE) secretion from astrocytes in brain lipid metabolism and the strong association of apoE4, one of the human apoE isoforms, with sporadic and late onset forms of Alzheimer's disease (AD) little is known about the regulation of astrocytic apoE. Utilizing annotated chemical libraries and a phenotypic screening strategy that measured apoE secretion from a human astrocytoma cell line, inhibition of pan class I histone deacetylases (HDACs) was identified as a mechanism to increase apoE secretion. Knocking down select HDAC family members alone or in combination revealed that inhibition of the class I HDAC family was responsible for enhancing apoE secretion. Knocking down LXRalpha and LXRbeta genes revealed that the increase in astrocytic apoE in response to HDAC inhibition occurred via an LXR-independent pathway. Collectively, these data suggest that pan class I HDAC inhibition is a novel pathway for regulating astrocytic apoE secretion. PMID- 29579089 TI - To be understood: Transitioning to adult life for people with Autism Spectrum Disorder. AB - INTRODUCTION: The purpose of this study was to explore the viewpoints of parents of young people with Autism Spectrum Disorder (ASD) in relation to their child's transition to adulthood. METHODS: Data were collected during four structured focus groups with 19 parents of young people with ASD with average to high intellectual capacities. Condensed meaning units were identified and checked during focus groups, and were subsequently linked to the International Classification of Functioning, Disability and Health (ICF). RESULTS: Three major themes emerged: to be understood, to understand the world and to succeed. The ICF domains of activity and participation and environmental factors emerged as having the greatest potential to influence transition outcomes. CONCLUSIONS: Policies and services should focus on strengths to maximise participation in higher education, employment and independent living amongst young people with ASD. Interventions targeting environmental factors could be effective in improving participation in adult life. Person-centred and individualised approaches could further complement this approach supporting the transition to adulthood for people with ASD, ultimately improving outcomes in adulthood. PMID- 29579090 TI - Cytotoxic effects of four different root canal sealers on human osteoblasts. AB - The aim of this study was to evaluate the effect of an epoxy resin-based (AH Plus), a zinc oxide eugenol containing (Pulp-Canal-Sealer) and two calcium silicate containing (MTA-Fillapex and BioRoot-RCS) sealers on primary human osteoblasts (hOB) in freshly mixed and set state. All sealers were mixed strictly according to the manufacturers' instructions and identically samples were produced. In a pretest cytotoxic sealer concentrations were determined. Thus, for the main cell culture study, dilutions of sealer extract 1:1, 1:2, and 1:10 were used. To simulate a clinical scenario, extracts from freshly mixed sealer were added to the cells on day one. Extracts form set sealers were used for subsequent culturing for 24h, 7d, 14d, and 21d. Cell viability was analyzed by living-cell count, MTT-assay, and living/dead-staining, cytotoxicity by LDH-assay, and changes by Richardson-staining. All data were statistically evaluated by one way ANOVA and a posthoc analysis with Bonferroni-Holm testing (p<0.05). AH-Plus was cytotoxic in a freshly mixed state, but not when the sealer was set. MTA-Fillapex and Pulp-Canal-Sealer were cytotoxic in a fresh as well as in a set state. BioRoot-RCS showed the lowest toxicity in both states; where as a regeneration of the cells could be observed over time (p<0.05). Contact of freshly mixed AH-Plus to osteoblasts should be avoided. Pulp Canal Sealer and MTA-Fillapex showed no biocompatibility in contact with osteoblasts at all. BioRoot-RCS had a positive influence on the cell metabolism (bioactivity) and is biocompatible. PMID- 29579091 TI - Delay models for the early embryonic cell cycle oscillator. AB - Time delays are known to play a crucial role in generating biological oscillations. The early embryonic cell cycle in the frog Xenopus laevis is one such example. Although various mathematical models of this oscillating system exist, it is not clear how to best model the required time delay. Here, we study a simple cell cycle model that produces oscillations due to the presence of an ultrasensitive, time-delayed negative feedback loop. We implement the time delay in three qualitatively different ways, using a fixed time delay, a distribution of time delays, and a delay that is state-dependent. We analyze the dynamics in all cases, and we use experimental observations to interpret our results and put constraints on unknown parameters. In doing so, we find that different implementations of the time delay can have a large impact on the resulting oscillations. PMID- 29579092 TI - Comparison of gizzard and intestinal microbiota of wild neotropical birds. AB - Gut bacterial communities have been shown to be influenced by diet, host phylogeny and anatomy, but most of these studies have been done in captive animals. Here we compare the bacterial communities in the digestive tract of wild birds. We characterized the gizzard and intestinal microbiota among 8 wild Neotropical bird species, granivorous or frugivorous species of the orders Columbiformes and Passeriformes. We sequenced the V4 region of the 16S rRNA gene in 94 collected samples from 32 wild birds from 5 localities, and compared bacterial communities by foraging guild, organ, locality and bird taxonomy. 16S rRNA gene-based sequencing data were examined using QIIME with linear discriminant analysis effect size (LEfSe) and metabolic pathways were predicted using PICRUSt algorism. We identified 8 bacterial phyla, dominated by Firmicutes, Actinobacteria and Proteobacteria. Beta diversity analyses indicated significant separation of gut communities by bird orders (Columbiformes vs. Passerifomes) and between bird species (p<0.01). In lower intestine, PICRUSt shows a predominance of carbohydrate metabolism in granivorous birds and xenobiotics biodegradation pathways in frugivorous birds. Gizzard microbiota was significantly richer in granivorous, in relation to frugivorous birds (Chao 1; non-parametric t-test, p<0.05), suggesting a microbial gizzard function, beyond grinding food. The results suggest that the most important factor separating the bacterial community structure was bird taxonomy, followed by foraging guild. However, variation between localities is also likely to be important, but this could not been assessed with our study design. PMID- 29579093 TI - How much is too much?-Influence of X-ray dose on root growth of faba bean (Vicia faba) and barley (Hordeum vulgare). AB - X-ray CT is a powerful technology to study root growth in soil in-situ. Root systems can be studied in its true 3D geometry over time. Hence, the same plant can be scanned multiple times during development. A downside is the potential of X-rays to interfere with biological processes and therefore plant growth. The aim of this study is to evaluate the influence of cumulative X-ray dose on Vicia faba and Hordeum vulgare during a growth period of 17 days. One control treatment without X-ray scanning was compared to two treatments being scanned every two and four days, respectively. Scanned treatments received a maximum cumulative dose of less than 8 Gy. Plant species differed in their susceptibility to X-ray dose. For Vicia faba, mean total root length was reduced significantly. Leave growth was reduced as well. Number and length of second order laterals was reduced significantly, as well as length of first order laterals. Hordeum vulgare showed no negative impact of X-ray dose on any of the root parameters. Large differences between the two species investigated were detected in respect to susceptibility to X-ray dose. Results indicate that for X-ray CT studies involving temporal resolution a control treatment without scanning is required. PMID- 29579094 TI - Abdominal obesity is a common finding in normal and overweight subjects of Chile and is associated with increased frequency of cardiometabolic risk factors. AB - BACKGROUND/OBJECTIVES: Abdominal obesity (AO) is associated with elevated risk for cardiovascular diseases; however, this association is less clear for non obese people. We estimated the association of AO and cardiovascular risk factors (CVRF) and disease in non-obese adult individuals from Chile. SUBJECTS/METHODS: 5248 adults (15 years of age or older) of both sexes from the Chilean National Health Survey (October 2009 -September 2010, response rate 85%.) were included. Information on myocardial infarction and stroke was self-reported. BMI, waist circumference (WC), arterial pressure, plasma glucose, and cholesterol levels were measured. Predictive accuracy of WC was evaluated by area under curve of receiver operating characteristic analysis and cut off points were established by Youden Index. Relationship between AO and CVRF was analyzed by Chi-squared tests. RESULTS: Normal weight/overweight/obesity were present in 34.4%/45.2%/18.1% of men and 33.4%/33.6%/27.5% of women. Predictive accuracy of WC to identify at least one CVRF was 0.70/0.67 and optimal cutoff points for WC in non-obese subjects were 91/83 cm in men/women, respectively. AO was present in 98.2%/99.1% of obese, 70.5%/77.4% of overweight and 12.4%/16.4% of normal weight men/women. AO was associated with increased frequency of CVRF in overweight men (6/8 and stroke) and women (4/8) and higher frequency in normal weight men (8/8 and myocardial infarction/stroke) and women (6/8 and myocardial infarction). CONCLUSIONS: WC cutoff points calculated for non-obese chilean population discriminate more differences in CVRF in normal weight woman. AO significantly increases the frequency of CVRF and diseases in overweight and especially normal weight individuals. WC can be used as a low cost, feasible and reproducible predictor for CVRF in non-obese individuals in most clinical settings. PMID- 29579095 TI - DNA strand-exchange patterns associated with double-strand break-induced and spontaneous mitotic crossovers in Saccharomyces cerevisiae. AB - Mitotic recombination can result in loss of heterozygosity and chromosomal rearrangements that shape genome structure and initiate human disease. Engineered double-strand breaks (DSBs) are a potent initiator of recombination, but whether spontaneous events initiate with the breakage of one or both DNA strands remains unclear. In the current study, a crossover (CO)-specific assay was used to compare heteroduplex DNA (hetDNA) profiles, which reflect strand exchange intermediates, associated with DSB-induced versus spontaneous events in yeast. Most DSB-induced CO products had the two-sided hetDNA predicted by the canonical DSB repair model, with a switch in hetDNA position from one product to the other at the position of the break. Approximately 40% of COs, however, had hetDNA on only one side of the initiating break. This anomaly can be explained by a modified model in which there is frequent processing of an early invasion (D loop) intermediate prior to extension of the invading end. Finally, hetDNA tracts exhibited complexities consistent with frequent expansion of the DSB into a gap, migration of strand-exchange junctions, and template switching during gap-filling reactions. hetDNA patterns in spontaneous COs isolated in either a wild-type background or in a background with elevated levels of reactive oxygen species (tsa1Delta mutant) were similar to those associated with the DSB-induced events, suggesting that DSBs are the major instigator of spontaneous mitotic recombination in yeast. PMID- 29579096 TI - Comparative pharmacokinetics and safety assessment of transdermal berberine and dihydroberberine. AB - The natural alkaloid berberine has been ascribed numerous health benefits including lipid and cholesterol reduction and improved insulin sensitivity in diabetics. However, oral (PO) administration of berberine is hindered by poor bioavailability and increasing dose often elicits gastro-intestinal side effects. To overcome the caveats associated with oral berberine, we developed transdermal (TD) formulations of berberine (BBR) and the berberine precursor dihydroberberine (DHB). These formulations were compared to oral BBR using pharmacokinetics, metabolism, and general safety studies in vivo. To complete this work, a sensitive quantitative LC-MS/MS method was developed and validated according the FDA guidelines for bioanalytical methods to simultaneously measure berberine, simvastatin, and simvastatin hydroxy acid with relative quantification used for the berberine metabolite demethylene berberine glucuronide (DBG). Acute pharmacokinetics in Sprague-Dawley rats demonstrated a statistically relevant ranking for berberine bioavailability based upon AUC0-8 as DHB TD > BBR TD >> BBR PO with similar ranking for the metabolite DBG, indicating that transdermal administration achieves BBR levels well above oral administration. Similarly, chronic administration (14 days) resulted in significantly higher levels of circulating BBR and DBG in DHB TD treated animals. Chronically treated rats were given a single dose of simvastatin with no observed change in the drugs bioavailability compared with control, suggesting the increased presence of BBR had no effect on simvastatin metabolism. This observation was further supported by consistent CYP3A4 expression across all treatment groups. Moreover, no changes in kidney and liver biomarkers, including alanine aminotransferase and alkaline phosphatase, were observed between treatment formats, and confirming previous reports that BBR has no effect on HMG-CoA expression. This study supports the safe use of transdermal compositions that improve on the poor bioavailability of oral berberine and have the potential to be more efficacious in the treatment of dyslipidemia or hypercholesterolemia. PMID- 29579097 TI - S-allylmercapto-N-acetylcysteine protects against oxidative stress and extends lifespan in Caenorhabditis elegans. AB - S-allylmercapto-N-acetylcysteine (ASSNAC) was shown in our previous study to activate Nrf2-mediated processes and increase glutathione level and resistance to oxidative stress in cultured endothelial cells. In this study, we explored the antioxidant protective effect of ASSNAC in Caenorhabditis elegans (C. elegans). Treatment of gst-4 reporter strain (CL2166) with increasing concentrations of ASSNAC (0.2 to 20 mM) for 24 hours and with ASSNAC (10 mM) for various time periods demonstrated a significant concentration- and time-dependent increase in Glutathione S-transferase (GST) gene expression (up to 60-fold at 20 mM after 24 hours). In addition, ASSNAC (2 mM; 24 hours) treatment of C. elegans strains N2 (wild type strain), gst-4 reporter (CL2166) and temperature sensitive sterile strain (CF512) significantly increased GST enzyme activity by 1.9-, 1.5- and 1.8 fold, respectively. ASSNAC (2.0 mM; 24 hours) increased the reduced glutathione content in N2 and CF512 strains by 5.9- and 4.9-fold, respectively. Exposure of C. elegans (N2 strain) to a lethal concentration of H2O2 (3.5 mM; 120 min) resulted in death of 88% of the nematodes while pretreatment with ASSNAC (24 hours) reduced nematodes death in a concentration-dependent manner down to 8% at 2.0 mM. C. elegans nematodes (strain CF512) cultured on agar plates containing ASSNAC (0.5 to 5.0 mM) demonstrated a significant increase in lifespan compared to control (mean lifespan 26.45 +/- 0.64 versus 22.90 +/- 0.59 days; log-rank p <= 0.001 at 2.0 mM) with a maximal lifespan of 40 versus 36 days. In conclusion, ASSNAC up-regulates the GST gene expression and enzyme activity as well as the glutathione content in C. elegans nematodes and thereby increases their resistance to oxidative stress and extends their lifespan. PMID- 29579098 TI - Low intensity vibration of ankle muscles improves balance in elderly persons at high risk of falling. AB - In our study we examined postural performance of young healthy persons (HY), elderly healthy persons (HE), and elderly persons at high risk of falling (FR). Anterio-posterior (AP) and medio-lateral (ML) ankle and hip angular deviations, as well as linear displacements of the center of mass (COM) were assessed in persons standing with eyes either open or closed, while none, and 40 and 30 Hz vibrations were applied bilaterally to the ankle muscle gastrocnemius. During quiet standing with eyes open, balance parameters in FR group differed from those in healthy groups. ML ankle and hip angular deviations, as well as COM linear displacements were noticeably larger in FR group. During quiet standing with eyes closed, all balance parameters in participants of all groups had a clear trend to increase. During standing with eyes open, 40 Hz vibration increased all but one balance parameter within HY group, ankle angular deviations in HE group, but none in FR group. In response to 30 Hz vibration, only ankle angular deviations and COM linear displacements increased in HY group. There were no changes in both elderly groups. During standing with eyes closed, 40 and 30 Hz vibrations did not produce consistent changes in balance parameters in HY and HE groups. In FR persons, 40 Hz vibration did not change balance parameters. However, in FR groups, 30 Hz vibration decreased ankle and hip angular deviations, and COM linear displacements. The major result of the study is a finding that low intensity vibration of ankle muscles makes balance better in elderly persons at high risk of falling. This result is clinically relevant because it suggests that applying mild vibration to ankle muscles while standing and walking might benefit elderly persons, improving their postural performance and reducing a risk of unexpected falls. PMID- 29579099 TI - Severe influenza A(H1N1)pdm09 in pregnant women and neonatal outcomes, State of Sao Paulo, Brazil, 2009. AB - To investigate the factors associated with death and describe the gestational outcomes in pregnant women with influenza A(H1N1)pdm09, we conducted a case control study (deaths and recovered) in hospitalized pregnant women with laboratory-confirmed influenza A(H1N1)pdm09 with severe acute respiratory illness (SARI) in the state of Sao Paulo from June 9 to December 1, 2009. All cases were evaluated, and four controls that were matched by the epidemiological week of hospitalization of the case were randomly selected for each case. Cases and controls were selected from the National Disease Notification System-SINAN Influenza-web. The hospital records from 126 hospitals were evaluated, and home interviews were conducted using standardized forms. A total of 48 cases and 185 controls were investigated. Having had a previous health visit to a healthcare provider for an influenza episode before hospital admission was a risk factor for death (adjusted OR (ORadj) of 7.93, 95% CI 2.19-28.69). Although not significant in the multiple analysis (ORadj of 2.13, 95% CI 0.91-5.00), the 3rd trimester deserves attention, with an OR = 2.22, 95% CI 1.13-4.37 in the univariate analysis. Antiviral treatment was a protective factor when administered within 48 hours of symptom onset (ORadj = 0.16, 95% CI 0.05-0.50) and from 48 to 72 hours (ORadj = 0.09, 95% CI 0.01-0.87). There was a higher proportion of fetal deaths and preterm births among cases (p = 0.001) and live births with low weight (p = 0.019), compared to control subjects who gave birth during hospitalization. After discharge, control subjects had a favorable neonatal outcome. Early antiviral treatment during the presence of a flu-like illness is an important factor in reducing mortality from influenza in pregnant women and unfavorable neonatal outcomes. It is important to monitor pregnant women, particularly in the 3rd trimester of gestation, with influenza illness for diagnosis and early treatment. PMID- 29579100 TI - Cerium enhances germination and shoot growth, and alters mineral nutrient concentration in rice. AB - Cerium (Ce) belongs to the rare earth elements (REEs), and although it is not essential for plants, it can stimulate growth and other physiological processes. The objective of this research was to evaluate the effect of Ce on seed germination, initial seedling growth, and vegetative growth in rice (Oryza sativa L.) cv. Morelos A-98. During the germination process, the seeds were treated with Ce concentrations of 0, 4, 8, and 12 MUM; after 5 d, germination percentage was recorded and after 10 d seedling growth was measured. For vegetative growth, a hydroponic system was established where 14-d-old plants without previous Ce treatment were transferred into nutrient solution. After two weeks of acclimatizing, 0, 25, 50, and 100 MUM Ce were added to the nutrient solution for 28 d. Ce significantly increased germination and the initial growth variables of the seedlings. During vegetative growth, Ce increased plant height, number of tillers, root volume, and shoot fresh and dry biomass, without affecting root biomass weight. With low Ce concentrations (25 and 50 MUM), the concentrations of chlorophylls and amino acids in the shoots were similar to those in the control, like amino acid concentration in the roots at a concentration of 25 MUM Ce. Conversely, the concentration of total sugars increased in the shoot with the application of 25, 50, and 100 MUM Ce, and in the roots with the application of 50 MUM Ce. Also, Ce did not affect the concentration of macro or micronutrients in the shoots. However, in the roots, the high Ce concentration decreased the concentrations of Ca, Fe, Mn, and Zn, while the Mg concentration increased. Our results indicate that Ce, at the right concentrations, can function as a biostimulant in rice germination and growth. PMID- 29579101 TI - Characterization of noise in multistable genetic circuits reveals ways to modulate heterogeneity. AB - Random fluctuations in the amount of cellular components like mRNA and protein molecules are inevitable due to the stochastic and discrete nature of biochemical reactions. If large enough, this so-called "cellular noise" can lead to random transitions between the expression states of a multistable genetic circuit. That way, heterogeneity within isogenic populations is created. Our aim is to understand which dynamical features of a simple autoregulatory system determine its intrinsic noise level, and how they can be modified in order to regulate state-transitions. To that end, novel mathematical methods for the state dependent characterization and prediction of noise in multistable systems are developed. First, we introduce the hybrid LNA, a modified version of the Linear Noise Approximation. It yields good predictions on variances of mRNA and protein fluctuations, even for reaction systems comprising low-copy-number components (e.g. mRNA) and highly nonlinear reaction rates. Furthermore, the temporal structure of fluctuations and the skewness of the protein distribution are characterized via state-dependent protein burst sizes and burst frequencies. Based on this mathematical framework, we develop graphical methods which support the intuitive design of regulatory circuits with a desired noise pattern. The methods are then used to predict how overall noise in the system can be adapted, and how state-specific noise modifications are possible that allow, e.g., the generation of unidirectional transitions. Our considerations are validated by stochastic simulations. This way, a design of genetic circuits is possible that takes population heterogeneity into account and is valuable in applications of synthetic biology and biotechnology. Moreover, natural phenomena like the bimodal development of genetic competence can be studied. PMID- 29579102 TI - Association between cognitive function and supplementation with omega-3 PUFAs and other nutrients in >= 75 years old patients: A randomized multicenter study. AB - A few studies have assessed the association between omega-3 polyunsaturated fatty acids (n-3 PUFA) and cognitive impairment (CI) in very old adults. The aim of this study was to evaluate the effect of a multinutrient supplementation rich in n-3 PUFA on the cognitive function in an institutionalized >=75-year-old population without CI or with mild cognitive impairment (MCI). A multicenter placebo-controlled double-blind randomized trial was conducted between 2012 and 2013. Cognitive function was assessed at baseline and after one year using 4 neuropsychological tests. Nutritional status was assessed using Mini Nutritional Assessment (MNA). Interaction between Mini-Mental State Examination (MMSE) score and nutritional status were analyzed using linear regression models. A total of 99 participants were randomized to receive placebo or pills rich in n-3 PUFA. After 1-year follow-up, both groups decreased their MMSE score (-1.18, SD:0. 53 and -0.82, SD:0. 63, p = 0.67 for the control and the intervention group respectively). The memory subscale of the MMSE showed an improvement (+0.26, SD:0.18) in the intervention group against a worsening in the control group ( 0.11, SD: 0.14; p = 0.09 for differences between groups). Patients at intervention group with normal nutritional status (MNA >=24) showed an improvement in the MMSE (+1.03, p = 0.025 for differences between 1-y and baseline measurements) against a worsening in the group with malnutrition (MNA<24) (-0.4, p = 0.886 for differences between 1-y and baseline; p of interaction p = 0.05). Supplementation with n-3 PUFA did not show an improvement in the global cognitive function in institutionalized elderly people without CI or with MCI. They only suggest an apparent improvement in memory loss if previously they were well nourished. PMID- 29579103 TI - A metagenomic viral discovery approach identifies potential zoonotic and novel mammalian viruses in Neoromicia bats within South Africa. AB - Species within the Neoromicia bat genus are abundant and widely distributed in Africa. It is common for these insectivorous bats to roost in anthropogenic structures in urban regions. Additionally, Neoromicia capensis have previously been identified as potential hosts for Middle East respiratory syndrome (MERS) related coronaviruses. This study aimed to ascertain the gastrointestinal virome of these bats, as viruses excreted in fecal material or which may be replicating in rectal or intestinal tissues have the greatest opportunities of coming into contact with other hosts. Samples were collected in five regions of South Africa over eight years. Initial virome composition was determined by viral metagenomic sequencing by pooling samples and enriching for viral particles. Libraries were sequenced on the Illumina MiSeq and NextSeq500 platforms, producing a combined 37 million reads. Bioinformatics analysis of the high throughput sequencing data detected the full genome of a novel species of the Circoviridae family, and also identified sequence data from the Adenoviridae, Coronaviridae, Herpesviridae, Parvoviridae, Papillomaviridae, Phenuiviridae, and Picornaviridae families. Metagenomic sequencing data was insufficient to determine the viral diversity of certain families due to the fragmented coverage of genomes and lack of suitable sequencing depth, as some viruses were detected from the analysis of reads-data only. Follow up conventional PCR assays targeting conserved gene regions for the Adenoviridae, Coronaviridae, and Herpesviridae families were used to confirm metagenomic data and generate additional sequences to determine genetic diversity. The complete coding genome of a MERS-related coronavirus was recovered with additional amplicon sequencing on the MiSeq platform. The new genome shared 97.2% overall nucleotide identity to a previous Neoromicia-associated MERS related virus, also from South Africa. Conventional PCR analysis detected diverse adenovirus and herpesvirus sequences that were widespread throughout Neoromicia populations in South Africa. Furthermore, similar adenovirus sequences were detected within these populations throughout several years. With the exception of the coronaviruses, the study represents the first report of sequence data from several viral families within a Southern African insectivorous bat genus; highlighting the need for continued investigations in this regard. PMID- 29579104 TI - A Rac1-FMNL2 signaling module affects cell-cell contact formation independent of Cdc42 and membrane protrusions. AB - De novo formation of epithelial cell-cell contacts relies on actin-based protrusions as well as tightly controlled turnover of junctional actin once cells encounter each other and adhesion complexes assemble. The specific contributions of individual actin regulators on either protrusion formation or junctional actin turnover remain largely unexplored. Based on our previous findings of Formin-like 2 (FMNL2)-mediated control of junctional actin dynamics, we investigated its potential role in membrane protrusions and impact on newly forming epithelial contacts. CRISPR/Cas9-mediated loss of FMNL2 in human MCF10A cells combined with optogenetic control of Rac1 activity confirmed its critical function in the establishment of intercellular contacts. While lamellipodial protrusion rates remained unaffected, FMNL2 knockout cells were characterized by impaired filopodia formation similar to depletion of the Rho GTPase Cdc42. Silencing of Cdc42, however, failed to affect FMNL2-mediated contact formation. Hence, we propose a cell-cell contact-specific and Rac1-mediated function of FMNL2 entirely independent of Cdc42. Consistent with this, direct visualizations of native epithelial junction formation revealed a striking and specifically Rac1- and not Cdc42-dependent recruitment of FMNL2 to newly forming junctions as well as established cell-cell contacts within epithelial sheets. PMID- 29579105 TI - Neisseria Heparin Binding Antigen is targeted by the human alternative pathway C3 convertase. AB - Neisserial Heparin Binding Antigen (NHBA) is a surface-exposed lipoprotein specific for Neisseria and constitutes one of the three main protein antigens of the Bexsero vaccine. Meningococcal and human proteases, cleave NHBA protein upstream or downstream of a conserved Arg-rich region, respectively. The cleavage results in the release of the C-terminal portion of the protein. The C-terminal fragment originating from the processing of meningococcal proteases, referred to as C2 fragment, exerts a toxic effect on endothelial cells altering the endothelial permeability. In this work, we reported that recombinant C2 fragment has no influence on the integrity of human airway epithelial cell monolayers, consistent with previous findings showing that Neisseria meningitidis traverses the epithelial barrier without disrupting the junctional structures. We showed that epithelial cells constantly secrete proteases responsible for a rapid processing of C2 fragment, generating a new fragment that does not contain the Arg-rich region, a putative docking domain reported to be essential for C2 mediated toxic effect. Moreover, we found that the C3-convertase of the alternative complement pathway is one of the proteases responsible for this processing. Overall, our data provide new insights on the cleavage of NHBA protein during meningococcal infection. NHBA cleavage may occur at different stages of the infection, and it likely has a different role depending on the environment the bacterium is interacting with.

PMID- 29579106 TI - Impact of nutritional stress on drug susceptibility and biofilm structures of Burkholderia pseudomallei and Burkholderia thailandensis grown in static and microfluidic systems. AB - Burkholderia pseudomallei is the causative agent of melioidosis and regarded as a bioterrorism threat. It can adapt to the nutrient-limited environment as the bacteria can survive in triple distilled water for 16 years. Moreover, B. pseudomallei exhibits intrinsic resistance to diverse groups of antibiotics in particular while growing in biofilms. Recently, nutrient-limited condition influenced both biofilm formation and ceftazidime (CAZ) tolerance of B. pseudomallei were found. However, there is no information about how nutrient limitation together with antibiotics used in melioidosis treatment affects the structure of the biofilm produced by B. pseudomallei. Moreover, no comparative study to investigate the biofilm architectures of B. pseudomallei and the related B. thailandensis under different nutrient concentrations has been reported. Therefore, this study aims to provide new information on the effects of four antibiotics used in melioidosis treatment, viz. ceftazidime (CAZ), imipenem (IMI), meropenem (MEM) and doxycycline (DOX) on biofilm architecture of B. pseudomallei and B. thailandensis with different nutrient concentrations under static and flow conditions using confocal laser scanning microscopy. Impact of nutritional stress on drug susceptibility of B. pseudomallei and B. thailandensis grown planktonically or as biofilm was also evaluated. The findings of this study indicate that nutrient-limited environment enhanced survival of B. pseudomallei in biofilm after exposure to the tested antibiotics. The shedding planktonic B. pseudomallei and B. thailandensis were also found to have increased CAZ tolerance in nutrient-limited environment. However, killing activities of MEM and IMI were stronger than CAZ and DOX on B. pseudomallei and B. thailandensis both in planktonic cells and in 2-day old biofilm. In addition, MEM and IMI were able to inhibit B. pseudomallei and B. thailandensis biofilm formation to a larger extend compared to CAZ and DOX. Differences in biofilm architecture were observed for biofilms grown under static and flow conditions. Under static conditions, biofilms grown in full strength modified Vogel and Bonner's medium (MVBM) showed honeycomb-like architecture while a knitted-like structure was observed under limited nutrient condition (0.1*MVBM). Under flow conditions, biofilms grown in MVBM showed a multilayer structure while merely dispersed bacteria were found when grown in 0.1*MVBM. Altogether, this study provides more insight on the effect of four antibiotics against B. pseudomallei and B. thailandensis in biofilm under different nutrient and flow conditions. Since biofilm formation is believed to be involved in disease relapse, MEM and IMI may be better therapeutic options than CAZ for melioidosis treatment. PMID- 29579108 TI - The association between BMI and body weight perception among children and adolescents in Jilin City, China. AB - OBJECTIVES: We evaluated the association between BMI and body weight perception in a sample of children and adolescents. METHODS: A cross-sectional school-based study was conducted among 7-18 year-olds (N = 9727) from 4 districts in Jilin City, China. We calculated BMI from measured weight and height and assessed body weight perception using a single questionnaire item. We analyzed these data using SPSS version 20.0. RESULTS: Approximately 19.8% of these youth perceived themselves as underweight, 57.8% as normal weight, and 22.4% as overweight. In reality, 4.9% were underweight, 64.3% were normal weight, and 30.8% were overweight. Furthermore, approximately 66.4% of these Chinese youth correctly perceived their body image, 28.2% underestimated their true body image, and 5.4% overestimated their weight status. Girls were more likely than boys to overestimate their weight (chi2 = 135.4, p < 0.05). Adolescents 13-18 years old were more likely than children 7-12 years old to overestimate their weight (chi2 = 248.4, p < 0.05). Senior high school students were the most likely to overestimate their weight (chi2 = 297.6, p < 0.05). Kappa tests revealed significant differences in consistency analysis of BMI and body weight perception (Kappa = 0.352, p < 0.05). Kappa < 0.4, the consistency of BMI and body weight perception was poor. CONCLUSIONS: A mismatch existed between BMI and body weight perception among these children and adolescents. Thus, schools and parents should take steps to help them improve weight management and overall health awareness. PMID- 29579109 TI - Using data linkage to electronic patient records to assess the validity of selected mental health diagnoses in English Hospital Episode Statistics (HES). AB - BACKGROUND: Administrative data can be used to support research, such as in the UK Biobank. Hospital Episode Statistics (HES) are national data for England that include contain ICD-10 diagnoses for inpatient mental healthcare episodes, but the validity of these diagnoses for research purposes has not been assessed. METHODS: 250 peoples' HES records were selected based on a HES recorded inpatient stay at the South London and Maudsley NHS Foundation Trust with a diagnosis of schizophrenia, a wider schizophrenia spectrum disorder, bipolar affective disorder or unipolar depression. A gold-standard research diagnosis was made using Clinical Records Interactive Search pseudonymised electronic patient records using, and the OPCRIT+ algorithm. RESULTS: Positive predictive value at the level of lifetime psychiatric disorder was 100%, and at the level of lifetime diagnosis in the four categories of schizophrenia, wider schizophrenia spectrum, bipolar or unipolar depression was 73% (68-79). Agreement varied by diagnosis, with schizophrenia having the highest PPV at 90% (80-96). Each person had an average of five psychiatric HES records. An algorithm that looked at the last recorded psychiatric diagnosis led to greatest overall agreement with the research diagnosis. DISCUSSION: For people who have a HES record from a psychiatric admission with a diagnosis of schizophrenia spectrum disorder, bipolar affective disorder or unipolar depression, HES records appear to be a good indicator of a mental disorder, and can provide a diagnostic category with reasonable certainty. For these diagnoses, HES records can be an effective way of ascertaining psychiatric diagnosis.

PMID- 29579111 TI - Micro-habitat distribution drives patch quality for sub-tropical rocky plateau amphibians in the northern Western Ghats, India. AB - The importance of patch quality for amphibians is frequently overlooked in distribution models. Here we demonstrate that it is highly important for the persistence of endemic and endangered amphibians found in the threatened and fragile ecosystems that are the rocky plateaus in Western Maharashtra, India. These plateaus are ferricretes of laterite and characterise the northern section of the Western Ghats/Sri Lanka Biodiversity Hotspot, the eighth most important global hotspot and one of the three most threatened by population growth. We present statistically supported habitat associations for endangered and data deficient Indian amphibians, demonstrating significant relationships between individual species and their microhabitats. Data were collected during early monsoon across two seasons. Twenty-one amphibian taxa were identified from 14 lateritic plateaus between 67 and 1179m above sea level. Twelve of the study taxa had significant associations with microhabitats using a stepwise analysis of the AICc subroutine (distLM, Primer-e, v7). Generalist taxa were associated with increased numbers of microhabitat types. Non-significant associations are reported for the remaining 9 taxa. Microhabitat distribution was spatially structured and driven by climate and human activity. Woody plants were associated with 44% of high-elevation taxa. Of the 8 low-elevation taxa 63% related to water bodies and 60% of those were associated with pools. Rock size and abundance were important for 33% of high elevation specialists. Three of the 4 caecilians were associated with rocks in addition to soil and stream presence. We conclude the plateaus are individualistic patches whose habitat quality is defined by their microhabitats within climatic zones.

AB - Despite an increase in dengue outbreaks and the arrival of chikungunya and Zika disease in Panama, studies on the demographic history of the invasive Aedes mosquitoes that are the principle vectors of these diseases are still lacking in this region. Here, we assess the genetic diversity of these mosquitoes in order to decipher their invasion histories into the Isthmus of Panama. DNA sequences from the mitochondrial cytochrome C oxidase I gene obtained from 30 localities in 10 provinces confirmed the presence of more than one mitochondrial haplogroup (i.e., maternal lineage) in each species. The invasion of Aedes albopictus was likely from temperate European countries, as the most frequent and widespread haplogroup in Panama harbored variants that are uncommon elsewhere in the Americas. Two infrequent and geographically restricted Ae. albopictus haplotypes appear to have subsequently invaded Panama from neighboring Costa Rica and the USA, respectively. In addition, we recovered two deeply divergent mitochondrial clades in Panamanian Aedes aegypti. The geographic origins of these clades is unknown, given that divergence in the mitochondrial genome is probably due to ancient population processes within the native range of Ae. aegypti, rather than due to its global expansion out of Africa. However, Panamanian Ae. aegypti mitochondrial sequences within the first clade were closely related to others from Colombia, Bolivia, Brazil, Mexico and the USA, suggesting two separate invasions from Western Hemisphere source populations. The pattern of increased genetic diversity in Aedes mosquitoes in Panama is likely facilitated by the numerous land and water inter-connections across the country, which allows them to enter via sea- and land-transportation from Europe, North, Central and South America. Our results here should be considered in disease mitigation programs if emergent arboviruses are to be effectively diminished in Panama through vector suppression.

AB - From an evolutionary point of view a pathogen might benefit from regulating the inflammatory response, both in order to facilitate establishment of colonization and to avoid life-threatening host manifestations, such as septic shock. In agreement with this notion Streptococcus pyogenes exploits type I IFN-signaling to limit detrimental inflammation in infected mice, but the host-pathogen interactions and mechanisms responsible for induction of the type I IFN response have remained unknown. Here we used a macrophage infection model and report that S. pyogenes induces anti-inflammatory IL-10 in an M protein-dependent manner, a function that was mapped to the B- and C-repeat regions of the M5 protein. Intriguingly, IL-10 was produced downstream of type I IFN-signaling, and production of type I IFN occurred via M protein-dependent activation of the STING signaling pathway. Activation of STING was independent of the cytosolic double stranded DNA sensor cGAS, and infection did not induce detectable release into the cytosol of either mitochondrial, nuclear or bacterial DNA-indicating DNA independent activation of the STING pathway in S. pyogenes infected macrophages. These findings provide mechanistic insight concerning how S. pyogenes induces the type I IFN response and identify a previously unrecognized macrophage-modulating role for the streptococcal M protein that may contribute to curb the inflammatory response to infection.

AB - Ascorbic acid (AsA), chlorophyll and carotenoid contents and their associated gene expression patterns were analysed in Actinidia chinensis 'Hongyang' outer pericarp. The results showed chlorophyll degradation during fruit development and softening, exposed the yellow carotenoid pigments. LHCB1 and CLS1 gene expressions were decreased, while PPH2 and PPH3 gene expressions were increased, indicating that downregulation of chlorophyll biosynthesis and upregulation of its degradation, caused chlorophyll degradation. A decrease in the expression of the late carotenoid biosynthesis and maintenance genes (LCYB1, LCYE1, CYP1, CYP2, ZEP1, VDE1, VDE2, and NCED2) and degradation gene (CCD1), showed biosynthesis and degradation of carotenoid could be regulatory factors involved in fruit development. Most genes expression data of L-galactose and recycling pathway were agreement with the AsA concentrations in the fruit, suggesting these are the predominant pathways of AsA biosynthesis. GMP1, GME1 and GGP1 were identified as the key genes controlling AsA biosynthesis in 'Hongyang' outer pericarp. PMID- 29579115 TI - Metabolic Syndrome and cognitive decline in the elderly: A systematic review. AB - BACKGROUND: Metabolic Syndrome (MetS) refers to a cluster of metabolic disturbances which is associated with increased risk for vascular and degenerative conditions in general population. Although the relationship between vascular risk factors and dementia is undisputable, additional hazard for cognitive decline in older population with concurrent metabolic disorders still waits to be demonstrated. The present review aims to analyze data on MetS and risk for cognitive decline in elderly persons. METHODS: Database searches were performed in Medline, ISI and PsycINFO for articles assessing cognitive performances of older subjects with MetS. RESULTS: Of a total of 505 studies, 25 were selected for the review. Risk of selection biases was identified in all the studies. Although all articles followed recognized diagnostic recommendations for MetS, minor criteria modifications were detected in most of them. Hyperglycemia was consistently associated with impaired cognitive performances in older individuals, but the role of MetS for cognitive decline and for the onset of dementia showed heterogeneous results. DISCUSSION: Current available data in the literature concerning the impact of MetS on the cognition of older population is inconclusive and based on inconsistent evidence. Differential effects of individual MetS components and factors associated with the age of the sample may have accounted for divergent findings among articles, but larger and higher quality studies in this field are still needed. PMID- 29579116 TI - Reference gene selection for qRT-PCR analysis of flower development in Lagerstroemia indica and L. speciosa. AB - Quantitative real-time polymerase chain reaction (qRT-PCR) is a prevalent method for gene expression analysis, depending on the stability of the reference genes for data normalization. Lagerstroemia indica and L. speciosa are popular ornamental plants which are famous for the long flowering period. However, no systematic studies on reference genes in Lagerstroemia have yet been conducted. In the present study, we selected nine candidate reference genes (GAPDH, TUA, TUB, 18S, RPII, EF-1alpha, ATC, EIF5A and CYP) and evaluated their expression stability in different tissues during floral development of L. indica and L. speciosa using four algorithms (geNorm, NormFinder, BestKeeper and, RefFinder). Results showed that RPII and EF-1alpha were the most stably expressed and suitable reference genes for both of Lagerstroemia species. Moreover, ACT exhibited high expression stability in L. indica and GAPDH was a suitable reference gene for L. speciosa in different flower development stages. TUB was an unsuitable reference gene for gene expression normalization due to significant variations in expression across all samples. Finally, we verified the reliability of the selected candidate reference genes by amplifying an AGAMOUS homolog (LsAG1) of Arabidopsis thaliana. This study provides a list of suitable reference genes, thereby broadening the genetic basis of the gene expression patterns in Lagerstroemia species.

PMID- 29579118 TI - Niche overlap between a cold-water coral and an associated sponge for isotopically-enriched particulate food sources. AB - The cold-water coral Lophelia pertusa is an ecosystem engineer that builds reef structures on the seafloor. The interaction of the reef topography with hydrodynamics is known to enhance the supply of suspended food sources to the reef communities. However, the reef framework is also a substrate for other organisms that may compete for the very same suspended food sources. Here, we used the passive suspension feeder Lophelia pertusa and the active suspension feeding sponge Hymedesmia coriacea as model organisms to study niche overlap using isotopically-enriched algae and bacteria as suspended food sources. The coral and the sponge were fed with a combination of 13C-enriched bacteria/15N enriched algae or 15N-enriched bacteria/13C-enriched algae, which was subsequently traced into bulk tissue, coral skeleton and dissolved inorganic carbon (i.e. respiration). Both the coral and the sponge assimilated and respired the suspended bacteria and algae, indicating niche overlap between these species. The assimilation rates of C and N into bulk tissue of specimens incubated separately were not significantly different from assimilation rates during incubations with co-occurring corals and sponges. Hence, no evidence for exploitative resource competition was found, but this is likely due to the saturating experimental food concentration that was used. We do not rule out that exploitative competition occurs in nature during periods of low food concentrations. Food assimilation and respiration rates of the sponge were almost an order of magnitude higher than those of the cold-water coral. We hypothesize that the active suspension feeding mode of the sponge explains the observed differences in resource uptake as opposed to the passive suspension feeding mode of the cold-water coral. These feeding mode differences may set constraints on suitable habitats for cold-water corals and sponges in their natural habitats. PMID- 29579119 TI - High levels of caregiver burden in Prader-Willi syndrome. AB - OBJECTIVES: Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder that is characterized by hyperphagia, developmental delay, incomplete sexual development, mild-to-moderate intellectual disability, and a variety of challenging behavioral and psychiatric symptoms. The characteristics of PWS can be difficult for caregivers to cope with and are likely to cause significant and long- term caregiver burden. The current study examined burden in 142 caregivers of children and adults with PWS living in the US using the Zarit Burden Interview (ZBI). The study aimed to measure the level of burden in caregivers of individuals with PWS, to explore the impact of PWS on caregiver quality of life, and to assess ZBI as an indicator of that impact. RESULTS: Caregivers participating in this study were predominantly mothers, 30-59 years old, non Hispanic Whites, married or in a relationship, with an annual household income slightly distributed towards higher income. Nearly 90% of the caregiver's children with PWS lived at home. Caregivers experienced high caregiver burden with an average ZBI score of 44.4 +/- 15.4. ZBI scores were highest for caregivers of teenage and young adult individuals with PWS (49.2 +/- 14.6 and 49.2 +/- 14.1, respectively), while those caring for older adults (>30) and the youngest age group had lower scores (38.6 +/-10.5 and 34.8 +/-12.5, respectively). Caregivers reported that caring for a person with PWS negatively impacted their romantic relationship, ability to work, sleep, and mood. Whereas we did not find strong correlations between family income or level of help the caregiver receives and ZBI scores, the results showed significant correlations and a linear relationship between ZBI scores and caregiver depressed mood, feelings of anxiety, negative romantic relationship impact, as well as sleep and work disruption. CONCLUSIONS: Our study reveals that PWS incurs high caregiver burden and impacts many aspects of the lives of caregiver. We identified the ZBI as a good predictor of that impact. Our findings draw attention to the critical unmet need for support for caregivers of individuals with PWS. PMID- 29579120 TI - HSV-1-induced disruption of transcription termination resembles a cellular stress response but selectively increases chromatin accessibility downstream of genes. AB - Lytic herpes simplex virus 1 (HSV-1) infection triggers disruption of transcription termination (DoTT) of most cellular genes, resulting in extensive intergenic transcription. Similarly, cellular stress responses lead to gene specific transcription downstream of genes (DoG). In this study, we performed a detailed comparison of DoTT/DoG transcription between HSV-1 infection, salt and heat stress in primary human fibroblasts using 4sU-seq and ATAC-seq. Although DoTT at late times of HSV-1 infection was substantially more prominent than DoG transcription in salt and heat stress, poly(A) read-through due to DoTT/DoG transcription and affected genes were significantly correlated between all three conditions, in particular at earlier times of infection. We speculate that HSV-1 either directly usurps a cellular stress response or disrupts the transcription termination machinery in other ways but with similar consequences. In contrast to previous reports, we found that inhibition of Ca2+ signaling by BAPTA-AM did not specifically inhibit DoG transcription but globally impaired transcription. Most importantly, HSV-1-induced DoTT, but not stress-induced DoG transcription, was accompanied by a strong increase in open chromatin downstream of the affected poly(A) sites. In its extent and kinetics, downstream open chromatin essentially matched the poly(A) read-through transcription. We show that this does not cause but rather requires DoTT as well as high levels of transcription into the genomic regions downstream of genes. This raises intriguing new questions regarding the role of histone repositioning in the wake of RNA Polymerase II passage downstream of impaired poly(A) site recognition. PMID- 29579122 TI - The Monty Hall problem revisited: Autonomic arousal in an inverted version of the game. AB - The asymmetry of autonomic arousal for potential losses and gains was assessed by the galvanic skin response (GSR) of participants playing classic and inverted versions of the Monty Hall problem (MHP). In both versions, the prize remained the same (a pen valued at L10 for the right answer), but in the modified version, prizes were received prior to choosing the door. Both experimental groups showed increased levels of GSR while completing the task, demonstrating increased autonomic arousal during the game. However, a robust difference in GSR was detected between classic and inverted versions of the MHP, thus demonstrating the differing autonomic arousal involved in deciding between the alternatives presented by the game. Participants experienced a stronger autonomic response when they could lose the prize than when they could win the prize. This experiment presents the first demonstration of this effect on the MHP. The stronger autonomic arousal for the inverted task may indicate a stronger emotional reaction and/or greater attentional focus than for the standard version of the task. These data demonstrate that potential losses increase arousal in more complex tasks than is typically shown. PMID- 29579121 TI - The combination of NAD+-dependent deacetylase gene deletion and the interruption of gluconeogenesis causes increased glucose metabolism in budding yeast. AB - Metabolic engineering focuses on rewriting the metabolism of cells to enhance native products or endow cells with the ability to produce new products. This engineering has the potential for wide-range application, including the production of fuels, chemicals, foods and pharmaceuticals. Glycolysis manages the levels of various secondary metabolites by controlling the supply of glycolytic metabolites. Metabolic reprogramming of glycolysis is expected to cause an increase in the secondary metabolites of interest. In this study, we constructed a budding yeast strain harboring the combination of triple sirtuin gene deletion (hst3? hst4? sir2?) and interruption of gluconeogenesis by the deletion of the FBP1 gene encoding fructose-1,6-bisphosphatase (fbp1?). hst3? hst4? sir2? fbp1? cells harbored active glycolysis with high glucose consumption and active ethanol productivity. Using capillary electrophoresis-time-of-flight mass spectrometry (CE-TOF/MS) analysis, hst3? hst4? sir2? fbp1? cells accumulated not only glycolytic metabolites but also secondary metabolites, including nucleotides that were synthesized throughout the pentose phosphate (PP) pathway, although various amino acids remained at low levels. Using the stable isotope labeling assay for metabolites, we confirmed that hst3? hst4? sir2? fbp1? cells directed the metabolic fluxes of glycolytic metabolites into the PP pathway. Thus, the deletion of three sirtuin genes (HST3, HST4 and SIR2) and the FBP1 gene can allow metabolic reprogramming to increase glycolytic metabolites and several secondary metabolites except for several amino acids. PMID- 29579123 TI - Temporal changes in electrocardiographic frontal QRS-T angle and survival in patients with heart failure. AB - BACKGROUND: Heart failure (HF) is associated with considerable mortality. The electrocardiographic frontal QRS-T angle is a simple parameter to measure, reflects changes in the direction of the repolarization sequence and predicts outcome in patients with HF. Data regarding temporal changes in the frontal QRS-T angle in patients with HF and its impact on outcome is limited. AIM: To evaluate temporal changes in the frontal QRS-T angle and its effect on survival in patients with HF. METHODS: Baseline and follow-up QRS-T angle were calculated from the frontal QRS and T axis of the 12-lead surface electrocardiogram. Patients were followed for survival. RESULTS: 2,929 HF patients were evaluated. Median interval between baseline ECG and follow-up ECG was 895 days, median follow-up time was 1526 days. Overall, the QRS-T angle tended to be stable, with minor changes in the angle over time. The median QRS-T angle change was +3 degrees (IQR -19 degrees to +30 degrees ). Overall survival during follow-up was 60%. Cox regression analysis after adjustment for significant predictors demonstrated that the QRS-T angle was an incremental predictor of increased mortality. A widening of the QRS-T angle during follow-up was independently associated with an increase in mortality, evident with an increase of the QRS-T angle difference above 0 degrees (P<0.0001 for the adjusted model). CONCLUSION: QRS-T angle is relatively stable in patients with HF and is a powerful predictor of outcome. Widening of the QRS-T angle has predictive value and is an ominous sign.

AB - Identity-based proxy re-signature (IDPRS) is a novel cryptographic primitive that allows a semi-trusted proxy to convert a signature under one identity into another signature under another identity on the same message by using a re signature key. Due to this transformation function, IDPRS is very useful in constructing privacy-preserving schemes for various information systems. Key revocation functionality is important in practical IDPRS for managing users dynamically; however, the existing IDPRS schemes do not provide revocation mechanisms that allow the removal of misbehaving or compromised users from the system. In this paper, we first introduce a notion called revocable identity based proxy re-signature (RIDPRS) to achieve the revocation functionality. We provide a formal definition of RIDPRS as well as its security model. Then, we present a concrete RIDPRS scheme that can resist signing key exposure and prove that the proposed scheme is existentially unforgeable against adaptive chosen identity and message attacks in the standard model. To further improve the performance of signature verification in RIDPRS, we introduce a notion called server-aided revocable identity-based proxy re-signature (SA-RIDPRS). Moreover, we extend the proposed RIDPRS scheme to the SA-RIDPRS scheme and prove that this extended scheme is secure against adaptive chosen message and collusion attacks. The analysis results show that our two schemes remain efficient in terms of computational complexity when implementing user revocation procedures. In particular, in the SA-RIDPRS scheme, the verifier needs to perform only a bilinear pairing and four exponentiation operations to verify the validity of the signature. Compared with other IDPRS schemes in the standard model, our SA-RIDPRS scheme greatly reduces the computation overhead of verification. PMID- 29579126 TI - Improved methods of DNA extraction from human spermatozoa that mitigate experimentally-induced oxidative DNA damage. AB - Current approaches for DNA extraction and fragmentation from mammalian spermatozoa provide several challenges for the investigation of the oxidative stress burden carried in the genome of male gametes. Indeed, the potential introduction of oxidative DNA damage induced by reactive oxygen species, reducing agents (dithiothreitol or beta-mercaptoethanol), and DNA shearing techniques used in the preparation of samples for chromatin immunoprecipitation and next generation sequencing serve to cofound the reliability and accuracy of the results obtained. Here we report optimised methodology that minimises, or completely eliminates, exposure to DNA damaging compounds during extraction and fragmentation procedures. Specifically, we show that Micrococcal nuclease (MNase) digestion prior to cellular lysis generates a greater DNA yield with minimal collateral oxidation while randomly fragmenting the entire paternal genome. This modified methodology represents a significant improvement over traditional fragmentation achieved via sonication in the preparation of genomic DNA from human spermatozoa for downstream applications, such as next-generation sequencing. We also present a redesigned bioinformatic pipeline framework adjusted to correctly analyse this form of data and detect statistically relevant targets of oxidation. PMID- 29579127 TI - Prognostic factors in epithelial ovarian cancer: A population-based study. AB - The overall survival (OS) of patients with ovarian cancer is poor while epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer. The aim of the present study was to evaluate the clinico-pathologic characteristics, especially the prognostic factors, for patients with epithelial ovarian cancer (EOC) in Taiwan. Information about newly diagnosed patients with EOC from 2009 to 2012 was retrieved from the database of the Taiwan Cancer Registry. Data from 2009 to 2013 for the respective cases from the claims database of Taiwan's National Health Insurance and National Death Registry were then retrieved. Potential prognostic factors were analyzed. The mean age at diagnosis of the 2,498 patients was 52.8 years. Serous carcinoma and clear cell carcinoma were diagnosed in 43.3% and 22.8% of the total patients, respectively. For patients with early-stage disease, taxane-based adjuvant chemotherapy, stage I, and younger age at diagnosis led to better overall survival (p = 0.030, p = 0.002, p<0.001, respectively) in multivariable analysis. For advanced-stage patients, histology (endometrioid type), taxane-based adjuvant chemotherapy, stage, and age at diagnosis had a significant impact on OS (p<0.001, p = 0.020, p<0.001, p<0.001, respectively). In conclusion, taxane-based chemotherapy impacts the outcome of patients with EOC. Personalized medicine may be needed for different histological types of EOC because of their different outcomes.

AB - Melioidosis is a fatal infection caused by the soil saprophyte Burkholderia pseudomallei. Early diagnosis and befitting medical management can significantly influence the clinical outcomes among patients with melioidosis. Witnessing an annual increment in the number of melioidosis cases, over the past few years, mainly from the developing tropical nations, the present study was undertaken to evaluate the diagnostic utility of Active Melioidosis DetectTMLateralFlow Assay (AMD-LFA), in comparison with enrichment culture and PCR. A total of 206clinical specimens obtained from 175 patients with clinical suspicion of melioidosis were considered for the evaluation. Positivity for B.pseudomallei using enrichment culture, PCR and AMD-LFA were observed among 63 (30.5%), 55 (26.6%) and 63 (30.5%) specimens respectively. The AMD-LFA failed to detect melioidosis from 9 culture-confirmed cases (6 whole blood specimens, 2 pus samples, and one synovial fluid). Further the test gave faint bands from 9 urine samples which were negative by culture and PCR. AMD-LFA demonstrated a sensitivity, specificity, of 85.71%(CI:74.61% to 93.25%) and 93.62% (CI:88.23% to 97.04%), with positive predictive value of 85.71% (CI: 75.98% to 91.92%) and negative predictive value of 93.62% (CI:88.89% to 96.42%). The test needs further evaluation in view of the faint bands from negative urine samples, for incorporating the test as a point of care assay.In view of its rapidity and ease of testing AMD-LFA might be useful in early diagnosis of melioidosis at resource constraint settings. PMID- 29579129 TI - Estimating large carnivore populations at global scale based on spatial predictions of density and distribution - Application to the jaguar (Panthera onca). AB - Broad scale population estimates of declining species are desired for conservation efforts. However, for many secretive species including large carnivores, such estimates are often difficult. Based on published density estimates obtained through camera trapping, presence/absence data, and globally available predictive variables derived from satellite imagery, we modelled density and occurrence of a large carnivore, the jaguar, across the species' entire range. We then combined these models in a hierarchical framework to estimate the total population. Our models indicate that potential jaguar density is best predicted by measures of primary productivity, with the highest densities in the most productive tropical habitats and a clear declining gradient with distance from the equator. Jaguar distribution, in contrast, is determined by the combined effects of human impacts and environmental factors: probability of jaguar occurrence increased with forest cover, mean temperature, and annual precipitation and declined with increases in human foot print index and human density. Probability of occurrence was also significantly higher for protected areas than outside of them. We estimated the world's jaguar population at 173,000 (95% CI: 138,000-208,000) individuals, mostly concentrated in the Amazon Basin; elsewhere, populations tend to be small and fragmented. The high number of jaguars results from the large total area still occupied (almost 9 million km2) and low human densities (< 1 person/km2) coinciding with high primary productivity in the core area of jaguar range. Our results show the importance of protected areas for jaguar persistence. We conclude that combining modelling of density and distribution can reveal ecological patterns and processes at global scales, can provide robust estimates for use in species assessments, and can guide broad-scale conservation actions. PMID- 29579130 TI - Epidemiology and outcomes of anaphylaxis-associated out-of-hospital cardiac arrest. AB - BACKGROUND: Understanding the epidemiological characteristics of anaphylaxis associated out-of-hospital cardiac arrest (OHCA) is the first step toward developing preventative strategies and optimizing care systems. We aimed to describe and compare epidemiological features and clinical outcomes among patients with anaphylaxis-associated OHCAs according to causative agent groups. METHODS: We identified emergency medical service (EMS)-treated anaphylaxis associated OHCA patients from a nationwide OHCA registry between 2008 and 2015. We compared epidemiological characteristics and outcomes according to causal agents (a natural agents group and an iatrogenic agents group) and evaluated temporal variability in incidence. Multivariate logistic regression analysis was performed to compare survival to discharge between causative agent groups. RESULTS: During the study period (8 years), the total number of anaphylaxis associated OHCAs was 233. A total of 224 eligible cases were included in the analysis. There were 192 patients (85.6%) in the natural agents group and 32 patients (14.3%) in the iatrogenic agents group. There was significant diurnal and seasonal variability in the frequency of anaphylaxis-associated OHCAs (p values<0.01 for both), with the highest incidences occurring during the day (7:01 am to 3 pm; 64.6%) and in summer (June to August, 48.7%). Compared with the natural agents group, the adjusted odds ratio (AOR) for survival to discharge in the iatrogenic agents group was statistically insignificant (AOR 3.61, 95% CI 0.86 to 15.06). CONCLUSION: The incidence of anaphylaxis-associated OHCA is considerably low, and significant temporal variability, with a peak during the day and in summer, is evident. Anaphylaxis-associated OHCA is more common by natural agents than by iatrogenic agents, but no difference in the survival-to discharge rate is evident. PMID- 29579131 TI - Cost-effectiveness of breast cancer screening using mammography in Vietnamese women. AB - BACKGROUND: The incidence rate of breast cancer is increasing and has become the most common cancer in Vietnamese women while the survival rate is lower than that of developed countries. Early detection to improve breast cancer survival as well as reducing risk factors remains the cornerstone of breast cancer control according to the World Health Organization (WHO). This study aims to evaluate the costs and outcomes of introducing a mammography screening program for Vietnamese women aged 45-64 years, compared to the current situation of no screening. METHODS: Decision analytical modeling using Markov chain analysis was used to estimate costs and health outcomes over a lifetime horizon. Model inputs were derived from published literature and the results were reported as incremental cost-effectiveness ratios (ICERs) and/or incremental net monetary benefits (INMBs). One-way sensitivity analyses and probabilistic sensitivity analyses were performed to assess parameter uncertainty. RESULTS: The ICER per life year gained of the first round of mammography screening was US$3647.06 and US$4405.44 for women aged 50-54 years and 55-59 years, respectively. In probabilistic sensitivity analyses, mammography screening in the 50-54 age group and the 55-59 age group were cost-effective in 100% of cases at a threshold of three times the Vietnamese Gross Domestic Product (GDP) i.e., US$6332.70. However, less than 50% of the cases in the 60-64 age group and 0% of the cases in the 45-49 age group were cost effective at the WHO threshold. The ICERs were sensitive to the discount rate, mammography sensitivity, and transition probability from remission to distant recurrence in stage II for all age groups. CONCLUSION: From the healthcare payer viewpoint, offering the first round of mammography screening to Vietnamese women aged 50-59 years should be considered, with the given threshold of three times the Vietnamese GDP per capita. PMID- 29579132 TI - Implementation of a seven-day hospitalist program to improve the outcomes of the weekend admission: A retrospective before-after study in Taiwan. AB - OBJECTIVE: Patients admitted during weekends may have worse outcomes than those during weekdays. Adjusting the practice of senior physicians over weekends may reduce the weekend effect. DESIGN: A controlled before-after study, with propensity score matching (PSM) for potential confounding variables, to compare outcomes between weekday and weekend admissions. SETTING: A 2000-bed medical centre in Taiwan. PARTICIPANTS: Hospitalised general medicine patients cared for by traditional internal medicine teams (pre-intervention cohort) and those cared for by hospitalists after introducing a seven-day hospitalist program in the first six-month (post-intervention cohort) and following three-year periods. MAIN OUTCOME MEASURES: Proportion of intensive care unit (ICU) admissions, cardiopulmonary resuscitation (CPR) events, and in-hospital mortality. RESULTS: The pre-intervention cohort included 982 patients. Significantly higher mortality rates (11.3% vs. 6.2%, p = 0.032) were recorded in the case of weekend admissions, with similar proportions of ICU admission and CPR events. The post intervention cohort included 601 patients. No significant difference was recorded in any of the main outcomes between weekday and weekend admissions. PSM for pre intervention and post-intervention cohort showed shorter LOS after intervention, with no difference in ICU admission, CPR, and morality for the weekday and weekend admissions, respectively. The three-year cohort that followed, consisting of 3315 patients, showed no difference of outcomes between weekday and weekend admissions. After PSM, there were no significant differences in ICU admission rates (1.0% vs. 1.8%), CPR (0.3% vs. 0.2%) events and hospital mortality rates (8.1% vs. 8.5%), when weekday and weekend admissions were compared. CONCLUSIONS: The seven-day hospitalist program shows potential in providing equally safe care for both weekday and weekend general medicine admissions with sustainable development.

AB - Novel rutin-loaded zein-sodium caseinate nanoparticles (ZP) with antioxidant activity in aqueous medium were investigated. The results showed that the sodium caseinate concentrations, dosages of rutin and ethanol volume fractions significantly affected the zein nanoparticles' characteristics. Concerning the antioxidant properties, the highest values of rutin loaded ZP obtained using 2, 2 diphenyl-1-picrylhydrazyl scavenging and 2 and 2'-azino-bis (3 ethylbenzothiazoline-6-sulphonic acid) decolourisation assays were 52.7% and 71.2%, respectively, and the total antioxidant capacity was 0.40 nmol g-1. The results suggest that zein-sodium caseinate nanoparticles can be used as a new nano carrier system for rutin or other water insoluble active ingredients.

AB - Objective: Some studies have shown that diagnosis threat (DT) could negatively impact the cognitive performance of undergraduate students who had sustained a mild traumatic brain injury. This study was designed to examine DT in people with acquired brain injury (ABI). As a second goal, we investigated the effect of stereotype lift as a way to overcome DT's harmful impact. The purpose of this study was also to examine the mechanisms mediating stereotype effects. Method: People with ABI and control participants were assigned to one of three conditions: DT, cognitive-neutral (in which the cognitive status of participants with ABI and the cognitive characteristics of the tasks were deemphasized), and stereotype lift (in which a downward comparison was made with another neurological group). Participants then completed neuropsychological tasks. Negative emotions, intrusive thoughts, task expectancy, and self-efficacy were assessed for mediation analyses. Results: Instructions impacted the performance of people with ABI, but not control participants. Compared to the cognitive neutral condition, participants with ABI in the DT condition performed worse on memory and executive tasks (but not on attention tasks). These effects were mediated by negative emotions. There was no increase in performance in the stereotype lift condition compared to the DT condition. Conclusions: This study showed that DT can aggravate the cognitive difficulties of people with ABI during neuropsychological assessment. The mediating role of negative emotions and the selective impact of DT on tasks that rely heavily on executive functioning are discussed in the light of the stereotype threat model. PMID- 29579135 TI - Observed Differences between Males and Females in Surgically Treated Carpal Tunnel Syndrome Among Non-manual Workers: A Sensitivity Analysis of Findings from a Large Population Study. AB - Objectives: We aimed at assessing whether differences among males and females in carpal tunnel syndrome (CTS) epidemiology might be attributable to segregation with respect to occupational biomechanical exposures or differential access to care by sex. Methods: We analysed surgically treated cases of CTS occurring among non-manual workers in Tuscany between 1997 and 2000. We conducted a Monte Carlo simulation to estimate the difference in occupational biomechanical exposures between males and females necessary to explain the observed incidence rate ratios. We also accounted for the sex-specific probability of receiving surgery after the diagnosis of CTS, as women were reported to be more likely to undergo surgery in a subset of our study population. We quantified the hypothetical biomechanical overload through the hand activity level (HAL) metric proposed by the American Conference of Governmental Industrial Hygienists. To quantify the effect of HAL on CTS risk, we assumed a prior distribution based on findings from two large cohort studies of industrial workers. Results: After adjustment for the probability of receiving surgery, women showed a 4-fold incidence of CTS as compared with men. To explain this association among non-manual workers, women should have an average value of HAL at least 5 points higher. Conclusions: Our analysis does not support the hypothesis that the difference in CTS incidence between males and females is entirely attributable to occupational risk factors or to differential access to surgery. The causal pathway between sex and CTS might include more determinants such as hormonal factors, anthropometric characteristics, and non-occupational exposure to biomechanical overload (e.g. household tasks). PMID- 29579137 TI - Trail-Making Test Part B: Evaluation of the Efficiency Score for Assessing Floor Level Change in Veterans. AB - Objective: The Trail Making Test - Part B (TMT-B) is a commonly used executive control measure with a known floor effect, limiting the ability to distinguish impairment among individuals unable to complete this task in the standard time limit. Our group previously proposed the TMT-B Efficiency Score (TMT-Be), which captures performance variability among examinees who fail to complete the task. The present study assesses the TMT-Be in a longitudinal clinical sample. Method: Data were collected via record review of veterans who underwent two clinical neuropsychological evaluations. We identified 30 veterans (mean age Visit 1:69 +/ 8.7 years) who were unable to complete TMT-B during at least one evaluation (mean days between visits = 615). Two scoring systems were utilized to examine performance variability: TMT-Be and TMT-B Prorated Score (TMT-Bpr). Results: TMT Be distribution was less skewed, but more platykuric, compared to TMT-Bpr. TMT-Be and TMT-Bpr were highly correlated. Both metrics correlated with psychomotor speed and another executive task, but not confrontation naming, providing both convergent and discriminant evidence of validity. TMT-Be, but not TMT-Bpr, detected significant decline in performance longitudinally. Age and education were significant predictors of the TMT-Be, but not TMT-Bpr, difference scores. Conclusions: Both metrics captured performance variability in a clinical sample and provided sufficient variance for examining floor-level performance on the TMT B. TMT-Be appeared to be less prone to creating outliers and more likely to detect change. The results support the utility of the TMT-Be metric in research and clinical settings. PMID- 29579138 TI - Breast Shape Analysis With Curvature Estimates and Principal Component Analysis for Cosmetic and Reconstructive Breast Surgery. AB - Background: Breast shape is defined utilizing mainly qualitative assessment (full, flat, ptotic) or estimates, such as volume or distances between reference points, that cannot describe it reliably. Objectives: We will quantitatively describe breast shape with two parameters derived from a statistical methodology denominated principal component analysis (PCA). Methods: We created a heterogeneous dataset of breast shapes acquired with a commercial infrared 3 dimensional scanner on which PCA was performed. We plotted on a Cartesian plane the two highest values of PCA for each breast (principal components 1 and 2). Testing of the methodology on a preoperative and postoperative surgical case and test-retest was performed by two operators. Results: The first two principal components derived from PCA are able to characterize the shape of the breast included in the dataset. The test-retest demonstrated that different operators are able to obtain very similar values of PCA. The system is also able to identify major changes in the preoperative and postoperative stages of a two stage reconstruction. Even minor changes were correctly detected by the system. Conclusions: This methodology can reliably describe the shape of a breast. An expert operator and a newly trained operator can reach similar results in a test/re-testing validation. Once developed and after further validation, this methodology could be employed as a good tool for outcome evaluation, auditing, and benchmarking. PMID- 29579140 TI - Significance of whole-genome duplications on the emergence of evolutionary novelties. AB - Acquisition of evolutionary novelties is a fundamental process for adapting to the external environment and invading new niches and results in the diversification of life, which we can see in the world today. How such novel phenotypic traits are acquired in the course of evolution and are built up in developing embryos has been a central question in biology. Whole-genome duplication (WGD) is a process of genome doubling that supplies raw genetic materials and increases genome complexity. Recently, it has been gradually revealed that WGD and subsequent fate changes of duplicated genes can facilitate phenotypic evolution. Here, we review the current understanding of the relationship between WGD and the acquisition of evolutionary novelties. We show some examples of this link and discuss how WGD and subsequent duplicated genes can facilitate phenotypic evolution as well as when such genomic doubling can be advantageous for adaptation. PMID- 29579139 TI - Methanol induces cytosolic calcium variations, membrane depolarization and ethylene production in arabidopsis and tobacco. AB - Background and Aims: Methanol is a volatile organic compound released from plants through the action of pectin methylesterases (PMEs), which demethylesterify cell wall pectins. Plant PMEs play a role in developmental processes but also in responses to herbivory and infection by fungal or bacterial pathogens. However, molecular mechanisms that explain how methanol could affect plant defences remain poorly understood. Methods: Using cultured cells and seedlings from Arabidopsis thaliana and tobacco BY2 expressing the apoaequorin gene, allowing quantification of cytosolic Ca2+, a reactive oxygen species (ROS) probe (CLA, Cypridina luciferin analogue) and electrophysiological techniques, we followed early plant cell responses to exogenously supplied methanol applied as a liquid or as volatile. Key Results: Methanol induces cytosolic Ca2+ variations that involve Ca2+ influx through the plasma membrane and Ca2+ release from internal stores. Our data further suggest that these Ca2+ variations could interact with different ROS and support a signalling pathway leading to well known plant responses to pathogens such as plasma membrane depolarization through anion channel regulation and ethylene synthesis. Conclusions: Methanol is not only a by-product of PME activities, and our data suggest that [Ca2+]cyt variations could participate in signalling processes induced by methanol upstream of plant defence responses. PMID- 29579141 TI - Where to search top-K biomedical ontologies? AB - Motivation: Searching for precise terms and terminological definitions in the biomedical data space is problematic, as researchers find overlapping, closely related and even equivalent concepts in a single or multiple ontologies. Search engines that retrieve ontological resources often suggest an extensive list of search results for a given input term, which leads to the tedious task of selecting the best-fit ontological resource (class or property) for the input term and reduces user confidence in the retrieval engines. A systematic evaluation of these search engines is necessary to understand their strengths and weaknesses in different search requirements. Result: We have implemented seven comparable Information Retrieval ranking algorithms to search through ontologies and compared them against four search engines for ontologies. Free-text queries have been performed, the outcomes have been judged by experts and the ranking algorithms and search engines have been evaluated against the expert-based ground truth (GT). In addition, we propose a probabilistic GT that is developed automatically to provide deeper insights and confidence to the expert-based GT as well as evaluating a broader range of search queries. Conclusion: The main outcome of this work is the identification of key search factors for biomedical ontologies together with search requirements and a set of recommendations that will help biomedical experts and ontology engineers to select the best-suited retrieval mechanism in their search scenarios. We expect that this evaluation will allow researchers and practitioners to apply the current search techniques more reliably and that it will help them to select the right solution for their daily work. Availability: The source code (of seven ranking algorithms), ground truths and experimental results are available at https://github.com/danielapoliveira/bioont-search-benchmark. PMID- 29579143 TI - Effort Testing in Dementia Assessment: A Systematic Review. AB - Objective: Interpretation of neuropsychological test data is only valid when appropriate effort has been exerted. Research, however, suggests that neuropsychologists do not always formally test for effort and that this may especially be the case in the context of dementia assessment. This review systematically examined the literature that has investigated the use of both purpose-built and embedded effort-sensitive indices in dementia, mild cognitive impairment (MCI), and healthy control samples. The aim was to determine which tests of effort are most sensitive to suboptimal effort and least sensitive to the type of cognitive impairment seen in dementia. Methods: A systematic search of databases was conducted to October 2017. There was no start date. Results: Twenty-five studies were included for review. The studies were divided into two categories according to methodology. One category of studies (n = 5) was reviewed using a tailored methodological quality rating checklist whilst the remaining studies (n = 20) were reviewed using the Crowe Critical Appraisal Tool (CCAT). Conclusions: The results of this review suggest that PVTs which take a hierarchical approach to effort testing such as the WMT, MSVT, and NV-MSVT are preferable for use with older adults who are under investigation for possible dementia. These tests go above and beyond the traditional pass/fail approach of more traditional tests of effort because they allow the examiner to analyze the examinee's profile of scores. The methodological limitations and challenges involved in this field of research are discussed. PMID- 29579144 TI - Gender and Ageing at Work in Chile: Employment, Working Conditions, Work-Life Balance and Health of Men and Women in an Ageing Workforce. AB - Objectives: In Chile, working after retirement age has grown substantially over the last years. This, in addition to the country's current discussion about extending retirement age, motivates the need of generating evidence on the occupational health and safety of the working old, with a special focus on women, who are critically disadvantaged in Chile's labour market. The objective of this paper is to describe and compare the ageing workforce of women and men in Chile in terms of labour market participation, employment and working conditions, work life balance, and health. The social determinants of health and employment sustainability frameworks guide this study. Data Sources: Cross-sectional data from three publicly available sources: the Chilean Labour Force Survey, NENE (2010); the first Chilean Employment and working conditions survey, ENETS (2009 2010) and the second National Health Survey, ENS (2009). Methods: Participation rates and employment conditions (NENE and ENETS), working conditions, occupational health and work-life balance (ENETS) and chronic health conditions (ENS) were described by 5-year age groups separately for women and men. Descriptions cover all age groups in order to identify trends and patterns characteristic of older workers. Results: Rates of occupation decrease sharply after age 54 in women and 59 in men. Ageing women and men who continue to work are more likely to be in own-account (self-employed) work than younger workers; in the case of women, in households as domestic workers, and men, in agriculture. Social protection and workplace rights are markedly reduced in older workers. Part-time work increases from the age of 50 onwards, especially among women, but average working hours do not decrease under 30 h a week for either women or men. Interestingly, between ages 60 and 64, there is a peak increase of day and night shift-work among women, which co-occurs with a peak in domestic work, possibly corresponding to women working as caretakers of elderly people. Several workplace risks continue to be high into old age: intensive work and demanding physical work, especially in men, and the combination of paid and unpaid care work in women, which continues to be high up to the age of 70 years. The health of older workers is better than that of non-working people of the same age, a gap which is markedly larger for women than men and tends to increase among women as they age. Conclusion: Results indicate that Chileans working into old age face precarious jobs with limited protection and several adverse working conditions. Noteworthy, women carry the double burden of paid and unpaid work into their late years. In addition, results suggest they are affected more profoundly by the healthy worker effect whereby the health condition determines the probability of finding and keeping a job-also known as a health selection mechanism-which increases as they age. These employment and working conditions indicate that working into old age is not yet sustainable in Chile and counts as evidence that needs to be taken into account in discussions about delaying the retirement age in the country, as well as incorporating support systems to alleviate the double work burden of ageing working women.

AB - Clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (CRISPR-Cas9) system was originally discovered in prokaryotes functioned as a part of the adaptive immune system. Because of its high efficiency and easy operability, CRISPR-Cas9 system has been developed to be a powerful and versatile gene editing tool shortly after its discovery. Given that multiple genetic alterations are the main factors that drive genesis and development of tumor, CRISPR-Cas9 system has been applied to correct cancer causing gene mutations and deletions and to engineer immune cells, such as chimeric antigen receptor T (CAR T) cells, for cancer immunotherapeutic applications. Recently, CRISPR-Cas9-based CAR T-cell preparation has been an important breakthrough in antitumor therapy. Here, we summarize the mechanism, delivery and the application of CRISPR-Cas9 in gene editing, and discuss the challenges and future directions of CRISPR-Cas9 in cancer immunotherapy. PMID- 29579147 TI - Cas9/sgRNA-based genome editing and other reverse genetic approaches for functional genomic studies in rice. AB - One of the important and direct ways of investigating the function of a gene is to characterize the phenotypic consequences associated with loss or gain-of function of the corresponding gene. These mutagenesis strategies have been successfully deployed in Arabidopsis, and subsequently extended to crop species including rice. Researchers have made vast advancements in the area of rice genomics and functional genomics, as it is a diploid plant with a relatively smaller genome size unlike other cereals. The advent of rice genome research and the annotation of high-quality genome sequencing along with the developments in databases and computer searches have enabled the functional characterization of unknown genes in rice. Further, with the improvements in the efficiency of regeneration and transformation protocols, it has now become feasible to produce sizable mutant populations in indica rice varieties also. In this review, various mutagenesis methods, the current status of the mutant resources, limitations and strengths of insertional mutagenesis approaches and also results obtained with suitable screens for stress tolerance in rice are discussed. In addition, targeted genome editing using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) or Cas9/single-guide RNA system and its potential applications in generating transgene-free rice plants through genome engineering as an efficient alternative to classical transgenic technology are also discussed. PMID- 29579148 TI - Reduced Pain and Accelerated Recovery Following Primary Breast Augmentation With Lightweight Breast Implants. AB - Background: The posttreatment pain associated with breast augmentation is a top concern of most patients and can affect the decision concerning surgery. Objectives: This study aimed to compare the posttreatment pain and recovery times of patients undergoing primary breast augmentation with lightweight vs full-mass implants of similar volumes. The authors hypothesized that the reduced mechanical strain applied by lightweight implants elicits less pain. Methods: In this retrospective, observational study, 100 women who had undergone primary breast augmentation with either a lightweight breast implant or a traditional full-mass silicone implant (n = 50), were contacted by phone and asked about their posttreatment experiences and overall satisfaction with the outcome. All women were treated by the same surgical team, and the two groups were matched by date of surgery. Results: Most patients in the two cohorts had a self-reported preoperative B cup size and relatively high tolerance to pain. On average, LWBI patients were 6 years older than those undergoing full-mass implantation (32.4 +/ 8.7 vs 26.2 +/- 8.0; P = .0004) and more had experienced at least one pregnancy (61.2% vs 24%, P = .0002). LWBI patients opted for implants 39 +/- 28.4 cc larger than patients in the control group. Subglandular placement was selected in most cases (LWBI: 83.7% and full-mass: 90.0%). Mean posttreatment pain was lower in the LWBI cohort (5.5 +/- 2.4 vs 6.5 +/- 2.4) and required a shorter duration of analgesics (3.87 +/- 1.77 days vs 5.26 +/- 2.94 days; P = .009). Age- and parity adjusted measures demonstrated a respective 2-day and 5-day shorter recovery period and return to normal activities interval in the LWBI versus full-mass implant cohorts (P = .04 and P = .002, respectively). Conclusions: As compared to traditional silicone filled full-mass implants, breast augmentations with B-Lite lightweight breast implants (G&G Biotechnology Ltd., Haifa, Israel) elicit less posttreatment pain and require less down-time, ultimately, meeting patients' quest for desired breast shape at minimal discomfort.

AB - Single-cell RNA sequencing (scRNA-seq) is currently transforming our understanding of biology, as it is a powerful tool to resolve cellular heterogeneity and molecular networks. Over 50 protocols have been developed in recent years and also data processing and analyzes tools are evolving fast. Here, we review the basic principles underlying the different experimental protocols and how to benchmark them. We also review and compare the essential methods to process scRNA-seq data from mapping, filtering, normalization and batch corrections to basic differential expression analysis. We hope that this helps to choose appropriate experimental and computational methods for the research question at hand. PMID- 29579149 TI - Genetic differentiation in cauline-leaf-specific wettability of a rosette-forming perennial Arabidopsis from two contrasting montane habitats. AB - Background and Aims: An altitudinal gradient of leaf wettability is often observed between and within species. To understand its functional significance, positional variation of leaf surfaces within plants should be taken into account. In rosette-forming plants, rosette leaves are near the ground and their adaxial surfaces are exposed, whereas cauline leaves are lifted from the ground throughout the reproductive season, and their abaxial surfaces are more exposed. Here, we investigated leaf wettability of cauline and rosette leaves of Arabidopsis halleri subsp. gemmifera growing in contrasting montane habitats along an altitudinal gradient at Mt Ibuki, Japan. Methods: We conducted field investigations and a growth chamber experiment to determine whether field observed variation in leaf wettability was caused by genetic differentiation. We further performed gene expression analysis of a wax-related gene, i.e. AhgCER1, a homologue of A. thaliana ECERIFERUM1 (CER1) that may be involved in differentiation of leaf wettability. Key Results: We found cauline-leaf specific genetic differentiation in leaf wettability between contrasting montane habitats. Cauline leaves of semi-alpine plants, especially on abaxial surfaces, were non wettable. Cauline leaves of low-altitudinal understorey plants were wettable, and rosette leaves were also wettable in both habitats. AhgCER1 expression corresponded to observed leaf wettability patterns. Conclusions: Low wettability of cauline leaves is hypothesized to keep exposed surfaces dry when they are wrapping flowering buds in early spring, and presumably protects flowering buds from frost damage. The genetic system that controls wax content, specifically for cauline leaves, should be involved in the observed genetic differentiation, and AhgCER1 control is a strong candidate for the underlying genetic mechanism.

PMID- 29579151 TI - Contrasting plant height can improve the control of rain-borne diseases in wheat cultivar mixture: modelling splash dispersal in 3-D canopies. AB - Background and Aims: Growing cultivars differing by their disease resistance level together (cultivar mixtures) can reduce the propagation of diseases. Although architectural characteristics of cultivars are little considered in mixture design, they could have an effect on disease, in particular through spore dispersal by rain splash, which occurs over short distances. The objective of this work was to assess the impact of plant height of wheat cultivars in mixtures on splash dispersal of Zymoseptoria tritici, which causes septoria tritici leaf blotch. Methods: We used a modelling approach involving an explicit description of canopy architecture and splash dispersal processes. The dispersal model computed raindrop interception by a virtual canopy as well as the production, transport and interception of splash droplets carrying inoculum. We designed 3-D virtual canopies composed of susceptible and resistant plants, according to field measurements at the flowering stage. In numerical experiments, we tested different heights of virtual cultivars making up binary mixtures to assess the influence of this architectural trait on dispersal patterns of spore-carrying droplets. Key Results: Inoculum interception decreased exponentially with the height relative to the main inoculum source (lower diseased leaves of susceptible plants), and little inoculum was intercepted further than 40 cm above the inoculum source. Consequently, tall plants intercepted less inoculum than smaller ones. Plants with twice the standard height intercepted 33 % less inoculum than standard height plants. In cases when the height of suscpeptible plants was doubled, inoculum interception by resistant leaves was 40 % higher. This physical barrier to spore-carrying droplet trajectories reduced inoculum interception by tall susceptible plants and was modulated by plant height differences between cultivars of a binary mixture. Conclusions: These results suggest that mixture effects on spore dispersal could be modulated by an adequate choice of architectural characteristics of cultivars. In particular, even small differences in plant height could reduce spore dispersal. PMID- 29579152 TI - Cardioprotection induced by a brief exposure to acetaldehyde: role of aldehyde dehydrogenase 2. AB - Aims: We previously demonstrated that acute ethanol administration protects the heart from ischaemia/reperfusion (I/R) injury thorough activation of aldehyde dehydrogenase 2 (ALDH2). Here, we characterized the role of acetaldehyde, an intermediate product from ethanol metabolism, and its metabolizing enzyme, ALDH2, in an ex vivo model of cardiac I/R injury. Methods and results: We used a combination of homozygous knock-in mice (ALDH2*2), carrying the human inactivating point mutation ALDH2 (E487K), and a direct activator of ALDH2, Alda 1, to investigate the cardiac effect of acetaldehyde. The ALDH2*2 mice have impaired acetaldehyde clearance, recapitulating the human phenotype. Yet, we found a similar infarct size in wild type (WT) and ALDH2*2 mice. Similar to ethanol-induced preconditioning, pre-treatment with 50 MUM acetaldehyde increased ALDH2 activity and reduced cardiac injury in hearts of WT mice without affecting cardiac acetaldehyde levels. However, acetaldehyde pre-treatment of hearts of ALDH2*2 mice resulted in a three-fold increase in cardiac acetaldehyde levels and exacerbated I/R injury. Therefore, exogenous acetaldehyde appears to have a bimodal effect in I/R, depending on the ALDH2 genotype. Further supporting an ALDH2 role in cardiac preconditioning, pharmacological ALDH2 inhibition abolished ethanol-induced cardioprotection in hearts of WT mice, whereas a selective activator, Alda-1, protected ALDH2*2 against ethanol-induced cardiotoxicity. Finally, either genetic or pharmacological inhibition of ALDH2 mitigated ischaemic preconditioning. Conclusion: Taken together, our findings suggest that low levels of acetaldehyde are cardioprotective whereas high levels are damaging in an ex vivo model of I/R injury and that ALDH2 is a major, but not the only, regulator of cardiac acetaldehyde levels and protection from I/R.

AB - Motivation: In a scenario where populations A, B1 and B2 (subpopulations of B) exist, pronounced differences between A and B may mask subtle differences between B1 and B2. Results: Here we present iterClust, an iterative clustering framework, which can separate more pronounced differences (e.g. A and B) in starting iterations, followed by relatively subtle differences (e.g. B1 and B2), providing a comprehensive clustering trajectory.

PMID- 29579155 TI - A polymorphism in the lysyl oxidase propeptide domain accelerates carcinogen induced cancer. AB - The propeptide (LOX-PP) domain of the lysyl oxidase proenzyme was shown to inhibit the transformed phenotype of breast, lung and pancreatic cells in culture and the formation of Her2/neu-driven breast cancer in a xenograft model. A single nucleotide polymorphism (SNP, rs1800449) positioned in a highly conserved region of LOX-PP results in an Arg158Gln substitution (humans). This arginine (Arg) >glutamine (Gln) substitution profoundly impaired the ability of LOX-PP to inhibit the invasive phenotype and xenograft tumor formation. To study the effect of the SNP in vivo, here we established a knock in (KI) mouse line (LOX-PPGln mice) expressing an Arg152Gln substitution corresponding to the human Arg158Gln polymorphism. Breast cancer was induced in wild-type (WT) and LOX-PPGln female mice beginning at 6 weeks of age by treatment with 7,12-dimethylbenz(a)anthracene (DMBA) in combination with progesterone. Time course analysis of tumor development demonstrated earlier tumor onset and shorter overall survival in LOX PPGln versus WT mice. To further compare the tumor burden in WT and LOX-PPGln mice, inguinal mammary glands from both groups of mice were examined for microscopic lesion formation. LOX-PPGln glands contained more lesions (9.6 versus 6.9 lesions/#4 bilateral). In addition, more DMBA-treated LOX-PPGln mice had increased leukocyte infiltrations in their livers and were moribund compared with DMBA-treated WT mice. Thus, these data indicate that the Arg->Gln substitution in LOX-PP could be an important marker associated with a more aggressive cancer phenotype and that this KI model is ideal for further mechanistic studies regarding the tumor suppressor function of LOX-PP. PMID- 29579154 TI - Specification of trophoblast from embryonic stem cells exposed to BMP4. AB - Trophoblast (TB) comprises the outer cell layers of the mammalian placenta that make direct contact with the maternal uterus and, in species with a highly invasive placenta, maternal blood. It has its origin as trophectoderm, a single epithelial layer of extra-embryonic ectoderm that surrounds the embryo proper at the blastocyst stage of development. Here, we briefly compare the features of TB specification and determination in the mouse and the human. We then review research on a model system that has been increasingly employed to study TB emergence, namely the BMP4 (bone morphogenetic protein-4)-directed differentiation of human embryonic stem cells (ESCd), and discuss why outcomes using it have proved so uneven. We also examine the controversial aspects of this model, particularly the issue of whether or not the ESCd represents TB at all. Our focus here has been to explore similarities and potential differences between the phenotypes of ESCd, trophectoderm, placental villous TB, and human TB stem cells. We then explore the role of BMP4 in the differentiation of human pluripotent cells to TB and suggest that it converts the ESC into a totipotent state that is primed for TB differentiation when self-renewal is blocked. Finally we speculate that the TB formed from ESC is homologous to the trophectoderm derived, invasive TB that envelopes the implanting conceptus during the second week of pregnancy. PMID- 29579156 TI - CEP55 promotes the proliferation and invasion of tumour cells via the AKT signalling pathway in osteosarcoma. AB - The molecular mechanisms underlying the development of osteosarcoma (OS) are not fully understood. In this study, we investigated for the first time the clinical significance and biological activity of centrosomal protein 55 (CEP55) in OS. We found that CEP55 was overexpressed in OS, and the CEP55 expression level in OS was correlated with metastasis and poor prognosis. Through in vitro experiments, we confirmed that CEP55 knockdown significantly induced cell cycle arrest at G1 phase and suppressed OS cell proliferation, migration and invasion. In addition, CEP55 knockdown suppressed OS tumour growth in nude mice. Global gene expression profiling of CEP55-silenced MNNG/HOS cells showed that the AKT pathway might be involved in the regulation of OS cell activity. Two downstream factors of AKT signalling, CCND1 and FN1, were found to have significantly higher expression in tumour tissues, and their mRNA expression levels were strongly correlated with CEP55 expression. To conclude, our data suggest that CEP55 can be used as a prognostic marker for OS, highlighting the significance of CEP55 signalling as a putative therapeutic target. PMID- 29579157 TI - Cellular prion protein is involved in decidualization of mouse uterus. AB - Prion protein (PrP) is encoded by a single copy gene Prnp in many cell and tissue types. PrP is very famous for its infectious conformers (PrPSC) resulting in transmissible spongiform encephalopathies. At present, physiological functions of its cellular isoform (PrPC) remain ambiguous. Although PrPC expression has been found in uterus, whether it functions in maternal-fetal dialogue during early pregnant is unknown. In this study, we examined PrPC mRNA and protein in the uterus of peri-implantation mice, and found that they were expressed with a spatiotemporal dynamic pattern. Interestingly, PrPC was significantly increased in the decidual zones around the implanting embryos at the implantation window stage. To further demonstrate that PrPC is involved in the decidualization of mouse uterus during embryo implantation, we constructed the artificial decidualization models and the delayed implantation models. Once the pseudopregnant mice were artificially induced to decidualization, the PrPC expression then increased significantly in the decidua zone. And also, if the delayed implantation embryos were allowed to implant, PrPC protein was also simultaneously improved in stromal cells surrounding the implanting embryos. Moreover, PrPC expression can be inhibited by progesterone but upregulated by estrogen in mouse uterus. These results suggest that PrPC may play an important role in embryo implantation and decidualization. PMID- 29579158 TI - Early BCG-Denmark and Neonatal Mortality Among Infants Weighing <2500 g: A Randomized Controlled Trial. AB - Background: BCG vaccine may reduce overall mortality by increasing resistance to nontuberculosis infections. In 2 randomized trials in Guinea-Bissau of early BCG Denmark (Statens Serum Institut) given to low-weight (LW) neonates (<2500 g at inclusion) to reduce infant mortality rates, we observed a very beneficial effect in the neonatal period. We therefore conducted the present trial to test whether early BCG-Denmark reduces neonatal mortality by 45%. We also conducted a meta analysis of the 3 BCG-Denmark trials. Methods: In 2008-2013, we randomized LW neonates to "early BCG-Denmark" (intervention group; n = 2083) or "control" (local policy for LW and no BCG-Denmark; n = 2089) at discharge from the maternity ward or at first contact with the health center. The infants were randomized (1:1) without blinding in blocks of 24. Data was analyzed in Cox hazards models providing mortality rate ratios (MRRs). We had prespecified an analysis censoring follow-up at oral poliovirus vaccine campaigns. Results: Early administration of BCG-Denmark was associated with a nonsignificant reduction in neonatal mortality rate (MRR, 0.70; 95% confidence interval [CI], .47-1.04) and a 34% reduction (0.66; .44-1.00) when censoring for oral poliovirus vaccine campaigns. There was no reduction in mortality rate for noninfectious diseases, but a 43% reduction in infectious disease mortality rate (MRR, 0.57; 95% CI, .35 .93). A meta-analysis of 3 BCG trials showed that early BCG-Denmark reduced mortality by 38% (MRR, 0.62; 95% CI, .46-.83) within the neonatal period and 16% (0.84; .71-1.00) by age 12 months. Conclusion: Early administration of BCG Denmark in LW infants is associated with major reductions in mortality rate. It is important that all LW infants receive early BCG in areas with high neonatal mortality rates. Clinical Trials Registration: NCT00625482. PMID- 29579159 TI - Reactivation of the Nkx2.5 cardiac enhancer after myocardial infarction does not presage myogenesis. AB - Aims: The contribution of resident stem or progenitor cells to cardiomyocyte renewal after injury in adult mammalian hearts remains a matter of considerable debate. We evaluated a cell population in the adult mouse heart induced by myocardial infarction (MI) and characterized by an activated Nkx2.5 enhancer element that is specific for multipotent cardiac progenitor cells (CPCs) during embryonic development. We hypothesized that these MI-induced cells (MICs) harbour cardiomyogenic properties similar to their embryonic counterparts. Methods and results: MICs reside in the heart and mainly localize to the infarction area and border zone. Interestingly, gene expression profiling of purified MICs 1 week after infarction revealed increased expression of stem cell markers and embryonic cardiac transcription factors (TFs) in these cells as compared to the non-mycoyte cell fraction of adult hearts. A subsequent global transcriptome comparison with embryonic CPCs and fibroblasts and in vitro culture of MICs unveiled that (myo )fibroblastic features predominated and that cardiac TFs were only expressed at background levels. Conclusions: Adult injury-induced reactivation of a cardiac specific Nkx2.5 enhancer element known to specifically mark myocardial progenitor cells during embryonic development does not reflect hypothesized embryonic cardiomyogenic properties. Our data suggest a decreasing plasticity of cardiac progenitor (-like) cell populations with increasing age. A re-expression of embryonic, stem or progenitor cell features in the adult heart must be interpreted very carefully with respect to the definition of cardiac resident progenitor cells. Albeit, the abundance of scar formation after cardiac injury suggests a potential to target predestinated activated profibrotic cells to push them towards cardiomyogenic differentiation to improve regeneration. PMID- 29579161 TI - Orthostatic hypotension and cognitive function: cross-sectional results from the ELSA-Brasil study. AB - Background: The association between orthostatic hypotension (OH) and cognitive impairment is controversial, and most studies have investigated older white adults from Western Europe and the United States. Therefore, we investigated the association between OH and cognitive performance in a large and racially diverse sample of adults using cross-sectional data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: OH was defined when systolic blood pressures (SBP) decreased 20 mmHg and/or diastolic blood pressure (DBP) decreased 10 mmHg from supine to standing position. We investigated the association between OH and composite global cognition, memory, verbal fluency (VF), and Trail Making test z-scores, using multiple linear regression models. We also investigated the association of orthostatic hypertension and SBP/DBP changes with cognitive performance, as well as the interaction between OH and compensatory heart rate (HR) after postural change on cognitive performance. Results: We evaluated 12,826 participants (mean age=51.5+/-9.0 years, 46% male, 53% white). Participants with OH (4% of the sample) had poorer z-scores for VF (beta=-0.108, 95% CI=-0.189; 0.025, p=0.01) than participants without OH. Orthostatic hypertension was also associated with worse performance on the VF test (beta=-0.080, 95% CI=-0.157; 0.003, p=0.04). SBP orthostatic change had a non-linear association with VF. The interaction terms between OH and compensatory increase in HR for the Trail Making Test z-score (p=0.09) was borderline significant, suggesting that participants who lack compensatory HR after postural change might have poorer performance. Conclusion: OH and orthostatic hypertension were associated with poorer performance on the VF test in participants from Brazil.

AB - See Li and Donohue (doi:10.1093/brain/awy089) for a scientific commentary on this article.Dominantly-inherited Alzheimer's disease is widely hoped to hold the key to developing interventions for sporadic late onset Alzheimer's disease. We use emerging techniques in generative data-driven disease progression modelling to characterize dominantly-inherited Alzheimer's disease progression with unprecedented resolution, and without relying upon familial estimates of years until symptom onset. We retrospectively analysed biomarker data from the sixth data freeze of the Dominantly Inherited Alzheimer Network observational study, including measures of amyloid proteins and neurofibrillary tangles in the brain, regional brain volumes and cortical thicknesses, brain glucose hypometabolism, and cognitive performance from the Mini-Mental State Examination (all adjusted for age, years of education, sex, and head size, as appropriate). Data included 338 participants with known mutation status (211 mutation carriers in three subtypes: 163 PSEN1, 17 PSEN2, and 31 APP) and a baseline visit (age 19-66; up to four visits each, 1.1 +/- 1.9 years in duration; spanning 30 years before, to 21 years after, parental age of symptom onset). We used an event-based model to estimate sequences of biomarker changes from baseline data across disease subtypes (mutation groups), and a differential equation model to estimate biomarker trajectories from longitudinal data (up to 66 mutation carriers, all subtypes combined). The two models concur that biomarker abnormality proceeds as follows: amyloid deposition in cortical then subcortical regions (~24 +/- 11 years before onset); phosphorylated tau (17 +/- 8 years), tau and amyloid-beta changes in cerebrospinal fluid; neurodegeneration first in the putamen and nucleus accumbens (up to 6 +/- 2 years); then cognitive decline (7 +/- 6 years), cerebral hypometabolism (4 +/- 4 years), and further regional neurodegeneration. Our models predicted symptom onset more accurately than predictions that used familial estimates: root mean squared error of 1.35 years versus 5.54 years. The models reveal hidden detail on dominantly-inherited Alzheimer's disease progression, as well as providing data-driven systems for fine-grained patient staging and prediction of symptom onset with great potential utility in clinical trials.

PMID- 29579164 TI - Daily Marital Tension and Symptom Severity in Older Adults With Diabetes or Osteoarthritis. AB - Background: Greater marital quality is associated with better psychological and physical health. The quality of daily marital interactions is likely to be especially important for individuals with chronic illness, but this question has received little attention. Purpose: Using data from two diary studies, the current study examined whether individuals with chronic illness would experience more severe symptoms on days with more marital tension due in part to greater negative affect on those days. Methods: The samples included individuals with knee osteoarthritis (OA, N = 145) or type 2 diabetes mellitus (T2DM, N = 129) and their spouses. Participants reported on daily marital interaction quality, affect, and symptom severity (patients only) for 22 days (knee OA) or 24 days (T2DM). Separate multilevel models were run for patients and spouses, controlling for the partner's marital tension and negative affect as well as both partners' daily marital enjoyment and positive affect. We examined same-day and across-day associations. Results: For individuals with T2DM or knee OA, more severe symptoms on days with more marital tension were due in part to their greater negative affect on those days. Individuals with knee OA who experienced more pain had more negative affect and marital tension the next day. Conclusions: Negative marital interactions may exacerbate physical symptoms. Effects of daily marital tension likely accumulate over time and have long-term implications for health.

AB - Transcription is regulated by transcription factor (TF) binding at promoters and distal regulatory elements and histone modifications that control the accessibility of these elements. Chromatin immunoprecipitation followed by sequencing (ChIP-seq) has become the standard assay for identifying genome-wide protein-DNA interactions in vitro and in vivo. As large-scale ChIP-seq data sets have been collected for different TFs and histone modifications, their potential to predict gene expression can be used to test hypotheses about the mechanisms of gene regulation. In addition, complementary functional genomics assays provide a global view of chromatin accessibility and long-range cis-regulatory interactions that are being combined with TF binding and histone remodeling to study the regulation of gene expression. Thus, ChIP-seq analysis is now widely integrated with other functional genomics assays to better understand gene regulatory mechanisms. In this review, we discuss advances and challenges in integrating ChIP-seq data to identify context-specific chromatin states associated with gene activity. We describe the overall computational design of integrating ChIP-seq data with other functional genomics assays. We also discuss the challenges of extending these methods to low-input ChIP-seq assays and related single-cell assays. PMID- 29579167 TI - Glucocorticoid Receptor Signaling Is Not Required for In Vivo Adipogenesis. AB - Regulation of adipogenesis is of major interest given that adipose tissue expansion and dysfunction are central to metabolic syndrome. Glucocorticoids (GCs) are important for adipogenesis in vitro. However, establishing a role for GCs in adipogenesis in vivo has been difficult. GC receptor (GR)-null mice die at birth, a time at which wild-type (WT) mice do not have fully developed white adipose depots. We conducted several studies aimed at defining the role of GC signaling in adipogenesis in vitro and in vivo. First, we showed that GR-null mouse embryonic fibroblasts (MEFs) have compromised ability to form adipocytes in vitro, a phenotype that can be partially rescued with a peroxisome proliferator activated receptor gamma agonist. Next, we demonstrated that MEFs are capable of forming de novo fat pads in mice despite the absence of GR or circulating GCs [by bilateral adrenalectomy (ADX)]. However, ADX and GR-null fat pads and their associated adipocyte areas were smaller than those in controls. Second, using adipocyte-specific luciferase reporter mice, we identified adipocytes in both WT and GR-null embryonic day (E)18 mouse embryos. Lastly, positive perilipin staining in WT and GR-null E18 embryos confirmed the presence of early white inguinal and brown adipocytes. Taken together, these results provide compelling evidence that GCs and GR augment but are not required for the development of functional adipose tissue in vivo.

PMID- 29579168 TI - Apixaban in patients at risk of stroke undergoing atrial fibrillation ablation. AB - Aims: It is recommended to perform atrial fibrillation ablation with continuous anticoagulation. Continuous apixaban has not been tested. Methods and results: We compared continuous apixaban (5 mg b.i.d.) to vitamin K antagonists (VKA, international normalized ratio 2-3) in atrial fibrillation patients at risk of stroke a prospective, open, multi-centre study with blinded outcome assessment. Primary outcome was a composite of death, stroke, or bleeding (Bleeding Academic Research Consortium 2-5). A high-resolution brain magnetic resonance imaging (MRI) sub-study quantified acute brain lesions. Cognitive function was assessed by Montreal Cognitive Assessment (MoCA) at baseline and at end of follow-up. Overall, 674 patients (median age 64 years, 33% female, 42% non-paroxysmal atrial fibrillation, 49 sites) were randomized; 633 received study drug and underwent ablation; 335 undertook MRI (25 sites, 323 analysable scans). The primary outcome was observed in 22/318 patients randomized to apixaban, and in 23/315 randomized to VKA {difference -0.38% [90% confidence interval (CI) -4.0%, 3.3%], non inferiority P = 0.0002 at the pre-specified absolute margin of 0.075}, including 2 (0.3%) deaths, 2 (0.3%) strokes, and 24 (3.8%) ISTH major bleeds. Acute small brain lesions were found in a similar number of patients in each arm [apixaban 44/162 (27.2%); VKA 40/161 (24.8%); P = 0.64]. Cognitive function increased at the end of follow-up (median 1 MoCA unit; P = 0.005) without differences between study groups. Conclusions: Continuous apixaban is safe and effective in patients undergoing atrial fibrillation ablation at risk of stroke with respect to bleeding, stroke, and cognitive function. Further research is needed to reduce ablation-related acute brain lesions. PMID- 29579171 TI - A comparison of early redo surgery rates in Mosaic porcine and Perimount bovine pericardial valves. AB - OBJECTIVES: The objective of this study was to compare rates of redo surgery for the Medtronic Mosaic 305 A Porcine Prosthesis and the Carpentier-Edwards Perimount Pericardial Aortic Bioprosthesis 2900. METHODS: This was a single centre retrospective observational study. We included all 1018 patients who underwent aortic valve replacement with a Mosaic (n = 216) or Perimount (n = 809) bioprosthesis between October 2000 and August 2008. The total follow-up was 1508 patient-years for the Mosaic valve and 5813 for the Perimount valve. The maximal follow-up and interquartile range were 14.8 and 7.0 years for the Mosaic valve and 15.1 and 5.6 years for the Perimount valve, respectively. A propensity score weighted version of the Cox model, Kaplan-Meier analysis and multivariate regression model was used. RESULTS: Despite no statistical difference in the number of non-structural valve deterioration cases between valves, redo surgery occurred earlier in 10 (4.6%) Mosaic than for 17 (2.1%) Perimount valves (P = 0.02) and was required for structural valve deterioration in 5 (2.3%) Mosaic valves when compared with 7 (0.9%; P = 0.04) Perimount valves. Four of 5 Mosaic failures occurred before 5 years, whereas all Perimount failures occurred after 5 years. Redo surgery for non-structural valve deterioration occurred in 3 patients with Mosaic valves (1.4%) and no patients with Perimount valves. Surgery for the remaining patients with Perimount valves was due to infection or aortic disease. CONCLUSIONS: Early redo surgery for structural valve degeneration was uncommon but occurred earlier for the Mosaic porcine than the Perimount bovine pericardial replacement aortic valve. PMID- 29579170 TI - miR-122 Regulates LHR Expression in Rat Granulosa Cells by Targeting Insig1 mRNA. AB - Luteinizing hormone/chorionic gonadotropin receptor (LHR) expression in the ovary is regulated by a messenger RNA (mRNA) binding protein, which specifically binds to the coding region of LHR mRNA. We have shown that miR-122, a short noncoding RNA, mediates LHR mRNA levels by modulating the expression of LHR mRNA-binding protein (LRBP) through the regulation of sterol regulatory element binding protein (SREBP) activation. The present results show that miR-122 regulates LRBP levels by increasing the processing of SREBP through the degradation of Insig1, the anchoring protein of SREBP. We present evidence showing that mRNA and protein levels of Insig1 undergo a time-dependent increase following the treatment of rat granulosa cells with follicle-stimulating hormone (FSH), which leads to a decrease in LRBP levels. Furthermore, overexpression of miR-122 using an adenoviral vector (AdmiR-122) abolished FSH-induced increases in Insig1 mRNA and protein. We further confirmed the role of Insig1 by showing that inhibition of Insig1 using a specific small interfering RNA prior to FSH treatment resulted in the abrogation of LHR upregulation. Silencing of Insig1 also reversed FSH mediated decreases in SREBP and LRBP activation. These results show that decreased levels of miR-122 increase Insig1 and suppress SREBP processing in response to FSH stimulation of rat granulosa cells. PMID- 29579172 TI - MicroRNAs in the Mammalian Gut Endocrine Lineage. AB - MicroRNAs (miRNAs) are small noncoding RNA molecules that modulate gene expression at the posttranscriptional level. Numerous reports have elucidated the importance of miRNAs in the regulation of a wide array of biological processes including metabolism and energy homeostasis. miRNAs in the endocrine pancreas have been intensively studied over the last 15 years and linked to pancreatic islet development and function. In comparison, knowledge of miRNAs in gut endocrine cells, or enteroendocrine cells (EECs), is severely lacking. EECs have important roles in systemic energy homeostasis, are highly relevant to type 2 diabetes etiology, and may be critical to the mechanisms that underlie the rapid positive metabolic effects of bariatric surgery. Very recent studies reveal that several miRNAs are highly enriched in mature EECs and/or in intestinal stem cells that are primed to the EEC lineage. Moreover, functional experiments in enteroids/intestinal organoids suggest that some of these miRNAs may be important for the regulation of EEC differentiation and function. Another report has raised the possibility that EECs secrete miRNAs into circulation. These intriguing findings merit further investigation, particularly as it pertains to EEC miRNAs as novel therapeutic targets in type 2 diabetes and related diseases.

PMID- 29579174 TI - Non-herbal tea consumption and ovarian cancer risk: a systematic review and meta analysis of observational epidemiologic studies with indirect comparison and dose response analysis. AB - Ovarian cancer (OC) accounts for 4% of female malignancies worldwide, and its prognosis is unfavorable. Currently available epidemiologic data suggest that non herbal tea consumption may reduce OC risk, but these evidences are inconsistent. A comprehensive literature search for observational epidemiologic studies reporting associations between non-herbal tea consumption and OC risk was conducted in electronic databases. A random-effects model was used to synthesize effect measures in binary meta-analysis, and adjusted indirect comparison was used to compare whether there was a difference in effects between green tea (GT) and black tea (BT). Both linear and non-linear models were used to explore the dose-response relationship. Fourteen studies were included, and we obtained an inverse and significant pooled estimate in binary meta-analysis [risk ratio (RR)pool = 0.76, 95% confidence interval (CI) 0.61-0.95, PCochran < 0.001, I2 = 81.5%]. No publication bias was identified in binary meta-analysis. In binary meta-analysis stratified by tea types, we observed a significant association for GT (RRpool = 0.64, 95% CI 0.45-0.90, PCochran = 0.071, I2 = 53.6%), but not BT (RRpool = 0.85, 95% CI 0.65-1.12, PCochran = 0.007, I2 = 65.9%). Indirect comparison, which treated BT as the reference, showed an inverse but non significant association (RRGT versus BT = 0.74, 95% CI 0.48-1.15). Both linear and non-linear models found that OC risk decreased as the consumption levels of total non-herbal tea increased. However, the dose-response relationship was stronger for GT when compared with BT. Our results suggest that non-herbal tea, especially GT, is associated with a reduced risk of OC. Future studies should explore biochemical evidence regarding the variation in chemopreventive effects between different types of non-herbal tea. PMID- 29579175 TI - The Cell Type-Specific Expression of Lhcgr in Mouse Ovarian Cells: Evidence for a DNA-Demethylation-Dependent Mechanism. AB - The luteinizing hormone receptor (LHCGR) is expressed at low levels in mural granulosa cells and cumulus cells of antral follicles and is induced dramatically in granulosa cells but not in cumulus cells by follicle-stimulating hormone (FSH). Therefore, we hypothesized that FSH not only activates transcription factors controlling Lhcgr expression but also alters other events to permit and enhance Lhcgr expression in granulosa cells but not in cumulus cells. In granulosa cells, the level of DNA methylation in the Lhcgr promoter region was significantly decreased by equine chorionic gonadotropin (eCG) in vivo. However, in cumulus cells, hypermethylation of the Lhcgr promoter remained after eCG stimulation. eCG induced estrogen production from testosterone (T) and retinoic acid (RA) synthesis in granulosa cells. When either T or RA in the presence or absence of FSH was added to granulosa cell cultures, the combined treatment with FSH and RA induced demethylation of Lhcgr-promoter region and Lhcgr expression. FSH-dependent RA synthesis was negatively regulated by coculture of granulosa cells with denuded oocytes, suggesting that oocyte-secreted factors downregulate RA production in cumulus cells where Lhcgr expression was not induced. Strikingly, treatment of cultured cumulus-oocyte complexes with a SMAD inhibitor, SB431542, significantly induced RA production, demethylation of Lhcgr-promoter region, and Lhcgr expression in cumulus cells. These results indicate the demethylation of the Lhcgr-promoter region is mediated, at least in part, by RA synthesis and is a key mechanism regulating the cell type-specific differentiation during follicular development. PMID- 29579176 TI - Cognitive Function, Consent for Participation, and Compliance With Wearable Device Protocols in Older Adults. AB - Background: Population-based studies of older adults increasingly use wearable devices to measure activity and sleep. Whether cognitive impairment reduces consent and compliance has not been assessed. Methods : In the context of a nationally representative cohort of community-dwelling adults aged 62-90, individuals were invited to participate in a sleep and activity substudy that required wearing a wrist actigraph for 72 consecutive hours. Cognitive function in the parent study was assessed with the survey adaptation of the Montreal Cognitive Assessment, and individuals were categorized as normal, mild cognitive impairment, or dementia. Participants were asked to press an event marker on the actigraph when they started trying to fall asleep and when they awoke each day. Logistic and negative binomial regressions were used to link cognitive status to nonconsent, returning usable data, wearing the actigraph three full days, ever taking the device off-wrist during the 3-day study period, and pushing the event markers, controlling for demographics. Results: Cognitive status was not associated with nonconsent, returning usable data, off-wrist, or missing days. However, individuals classified with dementia were more likely to miss bedtime and wake-up event markers. Individuals classified as mild cognitive impairment were more likely to miss wake-up event markers. Conclusions: Impaired cognition does not seem to be a barrier to compliance with simply wearing a device but may affect compliance with additional action such as pressing event markers.

AB - In 1997, nearly 20 years ago, we reported the phenotypes of follicle-stimulating hormone (FSH) beta (Fshb) null mice. Since then, these mice have been useful for various physiological and genetic studies in reproductive and skeletal biology. In a 2009 review titled "FSHbeta Knockout Mouse Model: A Decade Ago and Into the Future," I summarized the need for and what led to the development of an FSH deficient mouse model and its applications, including delineation of the emerging extragonadal roles of FSH in bone cells by using this genetic model. These studies opened up exciting avenues of research on osteoporosis and now extend into those on adiposity in postmenopausal women. Here, I summarize the progress made with this mouse model since 2009 with regard to FSH rerouting in vivo, deciphering the role of N-glycosylation on FSHbeta, roles of FSH in somatic-germ cell interactions in gonads, and provide a road map that is anticipated to emerge in the near future. Undoubtedly, the next 10 years should be an even more exciting time to explore the fertile area of FSH biology and its implications for basic and clinical reproductive physiology research.

PMID- 29579179 TI - A Bayesian framework for multiple trait colocalization from summary association statistics. AB - Motivation: Most genetic variants implicated in complex diseases by genome-wide association studies (GWAS) are non-coding, making it challenging to understand the causative genes involved in disease. Integrating external information such as quantitative trait locus (QTL) mapping of molecular traits (e.g. expression, methylation) is a powerful approach to identify the subset of GWAS signals explained by regulatory effects. In particular, expression QTLs (eQTLs) help pinpoint the responsible gene among the GWAS regions that harbor many genes, while methylation QTLs (mQTLs) help identify the epigenetic mechanisms that impact gene expression which in turn affect disease risk. In this work, we propose multiple-trait-coloc (moloc), a Bayesian statistical framework that integrates GWAS summary data with multiple molecular QTL data to identify regulatory effects at GWAS risk loci. Results: We applied moloc to schizophrenia (SCZ) and eQTL/mQTL data derived from human brain tissue and identified 52 candidate genes that influence SCZ through methylation. Our method can be applied to any GWAS and relevant functional data to help prioritize disease associated genes. Availability and implementation: moloc is available for download as an R package (https://github.com/clagiamba/moloc). We also developed a web site to visualize the biological findings (icahn.mssm.edu/moloc). The browser allows searches by gene, methylation probe and scenario of interest.

PMID- 29579181 TI - Earthworm-induced shifts in microbial diversity in soils with rare versus established invasive earthworm populations. AB - European earthworms have colonised many parts of Australia, although their impact on soil microbial communities remains largely uncharacterised. An experiment was conducted to contrast the responses to Aporrectodea trapezoides introduction between soils from sites with established (Talmo, 64 A. trapezoides m-2) and rare (Glenrock, 0.6 A. trapezoides m-2) A. trapezoides populations. Our hypothesis was that earthworm introduction would lead to similar changes in bacterial communities in both soils. The effects of earthworm introduction (earthworm activity and cadaver decomposition) did not lead to a convergence of bacterial community composition between the two soils. However, in both soils, the Firmicutes decreased in abundance and a common set of bacteria responded positively to earthworms. The increase in the abundance of Flavobacterium, Chitinophagaceae, Rhodocyclaceae and Sphingobacteriales were consistent with previous studies. Evidence for possible soil resistance to earthworms was observed, with lower earthworm survival in Glenrock microcosms coinciding with A. trapezoides rarity in this site, lower soil organic matter and clay content and differences in the diversity and abundance of potential earthworm mutualist bacteria. These results suggest that while the impacts of earthworms vary between different soils, the consistent response of some bacteria may aid in predicting the impacts of earthworms on soil ecosystems. PMID- 29579182 TI - eDNA from roots: a robust tool for determining Phytophthora communities in natural ecosystems. AB - Proper isolation and identification of Phytophthora species is critical due to their broad distribution and huge impact on natural ecosystems throughout the world. In this study, five different sites were sampled and seven methods were compared to determine the Phytophthora community. Three traditional isolation methods were conducted (i) soil baiting, (ii) filtering of the bait water and (iii) isolation from field roots using Granny Smith apples. These were compared to four sources of eDNA used for metabarcoding using Phytophthora-specific primers on (i) sieved field soil, (ii) roots from field, (iii) filtered baiting water and (iv) roots from bait plants grown in the glasshouse in soil collected from these sites. Six Phytophthora species each were recovered by soil baiting using bait leaves and from the filtered bait water. No Phytophthora species were recovered from Granny Smith apples. eDNA extracted from field roots detected the highest number of Phytophthora species (25). These were followed by direct DNA isolation from filters (24), isolation from roots from bait plants grown in the glasshouse (19), and DNA extraction from field soil (13). Therefore, roots were determined to be the best substrate for detecting Phytophthora communities using eDNA. PMID- 29579183 TI - Effects of bottom-water hypoxia on sediment bacterial community composition in a seasonally hypoxic enclosed bay (Omura Bay, West Kyushu, Japan). AB - The bacterial community strongly drives carbon and other biogeochemical cycles in marine sediment. However, little is known about the impact of dissolved oxygen (DO) availability on bacterial community composition. To fill this gap, we examined diversity, richness and structure of the bacterial population for three consecutive years (2011-2013) in the uppermost (0-5 and 0-7 mm depth) and the subsurface layers (5-10 and 7-14 mm depth) of Omura Bay, Kyushu, Japan, a seasonally hypoxic enclosed bay. Automated ribosomal intergenic spacer analysis revealed a unimodal pattern of diversity indices with DO, peaking at the suboxic (11 MUM O2) condition. Shifts in the bacterial communities were also evident in response to the availability of DO. Changes in the operational taxonomic units (OTUs) that were less abundant accounted for a large part of the community dissimilarity. It was further demonstrated that the relative abundance of OTUs affiliated with Gammaproteobacteria was correlated positively with DO, while that with Deltaproteobacteria was inversely correlated with DO. These results strongly suggest that DO availability of bottom water plays a fundamental role in shaping the bacterial community in sediment surfaces of shallow coastal areas.

PMID- 29579185 TI - Safety of lymphadenectomy during video-assisted thoracic surgery lobectomy: analysis from a national database. AB - OBJECTIVES: The Italian VATS Group database was accessed to evaluate whether preoperative and intraoperative factors may affect the safety of lymphadenectomy (LA) during video-assisted thoracic surgery lobectomy. METHODS: All video assisted thoracic surgery lobectomy procedures performed between 1 January 2014 and 30 March 2017 for non-small-cell lung cancer with cN0 or cN1 disease were identified in the database. LA safety was evaluated based on intraoperative (operative time, bleeding and conversion rate) and postoperative (30-day morbidity and mortality, chest drain duration and length of stay) outcomes and was correlated with the number of resected lymph nodes and the rates of nodal upstaging. Continuous variables were presented as mean +/- standard deviation and compared using the unpaired t-test; the chi2 test was used for categorical variables. Univariable analysis was performed on selected variables. Significant variables (P < 0.30) were entered into a Cox multivariable logistic regression model, using the overall and specific occurrence of complications as dependent variables. The Spearman's rank correlation coefficient was applied as needed. RESULTS: A total of 3181 cases (2077 men, 65.3%; mean age of 69 years) met the enrolment criteria. Final pathology was consistent with adenocarcinoma (n = 2262, 67.5%), squamous cell (n = 520, 15.5%), typical (n = 184, 5.5%) and atypical carcinoid (n = 48, 1.4%) and other (n = 335, 10%). The mean number of resected lymph nodes was 13.42 +/- 8.24; nodal upstaging occurred in 308 of 3181 (9.68%) cases. Six hundred and fifty-five complications were recorded in 404 (12.7%) patients; in this series, no mortality was observed. Univariable and multivariable analyses did not show any association between the extension of LA and intraoperative or postoperative outcomes. The number of resected lymph nodes and nodal upstagings showed a minimal correlation with intraoperative outcomes and a moderate correlation with postoperative air leak (rho = 0.35 and rho = 0.48, respectively), arrhythmia (rho = 0.29 and rho = 0.35, respectively), chest drain duration (rho = 0.35 and rho = 0.51, respectively) and length of stay (rho = 0.35). CONCLUSIONS: Based on the VATS Group data, video-assisted thoracic surgery LA proved to be safe and displayed good outcomes even when performed with an extended approach. PMID- 29579186 TI - Arrhythmias in congenital heart disease: a position paper of the European Heart Rhythm Association (EHRA), Association for European Paediatric and Congenital Cardiology (AEPC), and the European Society of Cardiology (ESC) Working Group on Grown-up Congenital heart disease, endorsed by HRS, PACES, APHRS, and SOLAECE. AB - The population of patients with congenital heart disease (CHD) is continuously increasing with more and more patients reaching adulthood. A significant portion of these young adults will suffer from arrhythmias due to the underlying congenital heart defect itself or as a sequela of interventional or surgical treatment. The medical community will encounter an increasing challenge as even most of the individuals with complex congenital heart defects nowadays become young adults. Within the past 20 years, management of patients with arrhythmias has gained remarkable progress including pharmacological treatment, catheter ablation, and device therapy. Catheter ablation in patients with CHD has paralleled the advances of this technology in pediatric and adult patients with structurally normal hearts. Growing experience and introduction of new techniques like the 3D mapping systems into clinical practice have been particularly beneficial for this growing population of patients with abnormal cardiac anatomy and physiology. Finally, device therapies allowing maintanence of chronotropic competence and AV conduction, improving haemodynamics by cardiac resynchronization, and preventing sudden death are increasingly used. For pharmacological therapy, ablation procedures, and device therapy decision making requires a deep understanding of the individual pathological anatomy and physiology as well as detailed knowledge on natural history and long-term prognosis of our patients. Composing expert opinions from cardiology and paediatric cardiology as well as from non-invasive and invasive electrophysiology this position paper was designed to state the art in management of young individuals with congenital heart defects and arrhythmias.

PMID- 29579189 TI - Cardiac voltage-gated sodium channel mutations associated with left atrial dysfunction and stroke in children. AB - Aims: Cardiac atrial arrhythmias are the most common type of heart rhythm disorders. Its genetic elucidation remains challenging with poor understanding of cellular and molecular processes. These arrhythmias usually affect elderly population but in rare cases, young children may also suffer from such electrical diseases. Severe complications, including stroke, are commonly age related. This study aims to identify a genetic link between electro-mechanic atrial dysfunction and stroke in children. Methods and results: In two unrelated boys of 11 and 14 years with both stroke and atrial arrhythmias, the clinical phenotype was determined through a complete physical examination, electrocardiogram (ECG), Holter ECG, and computed tomography. The genetic testing was performed on a large 95 genes panel implicated in myocardial electrical imbalance, using the next generation sequencing method. The panel also includes the genes usually associated with the development of cardiomyopathies. In one child, a left atrial dilation was observed. The 2nd boy suffered from atrial standstill. Both suffered from atrial bradycardia, flutter, and fibrillation. The complete genetic testing revealed the SCN5A c.3823G>A (p.D1275N) mutation in the first family, c.1141-2A>G and c.3157G>A (p.E1053K) mutations in the second family. Conclusion: Our results strengthen the association between Nav1.5 mutations and the occurrence of stroke in young patients. It emphasizes the need to look for atrial myopathy in the decision process for anticoagulation in young patients with atrial arrhythmic events. PMID- 29579190 TI - 27-Hydroxycholesterol Is an Estrogen Receptor beta-Selective Negative Allosteric Modifier of 17beta-Estradiol Binding. AB - Estrogens bind to two nuclear estrogen receptor (ER) subtypes, ERalpha and ERbeta, which are expressed in differing amounts in various tissues. The endogenous estrogen, 17beta-estradiol (E2), binds to both subtypes with nearly equal affinity and is the prototypical agonist. Selective estrogen receptor modulators (SERMs) may bind to both subtypes with equivalent affinities but have agonist activities in some tissues while having antagonist activities in others. In the present study, we demonstrate that the first reported endogenous SERM, 27 hydroxycholesterol (27-OHC), binds preferentially (>100-fold) to ERbeta over ERalpha. Furthermore, 27-OHC is not able to fully compete with E2 binding, suggesting the two may bind at different sites. We provide an allosteric ternary complex model for the simultaneous binding of 27-OHC and E2 to ERbeta, which accurately describes the binding data we have observed. We conclude that 27-OHC is a negative allosteric modifier of E2 binding, with an inhibitor constantof 50 nM and cooperativity factor (alpha) of 0.036. We also propose an in silico three dimensional model of the simultaneous binding to guide future experiments. Further study of this unique binding model may allow for the discovery of novel ERbeta-selective ligands and potentially explain the lack of effectiveness of ERbeta-selective agonists in humans vs preclinical models. PMID- 29579192 TI - New prospects for PCSK9 inhibition? PMID- 29579191 TI - Glycosyltransferase genes that cause monogenic congenital disorders of glycosylation are distinct from glycosyltransferase genes associated with complex diseases. AB - Glycosylation of proteins, lipids and proteoglycans in human cells involves at least 167 identified glycosyltransferases (GTfs), and these orchestrate the biosynthesis of diverse types of glycoconjugates and glycan structures. Mutations in this part of the genome-the GTf-genome-cause more than 58 rare, monogenic congenital disorders of glycosylation (CDGs). They are also statistically associated with a large number of complex phenotypes, diseases or predispositions to complex diseases based on Genome-Wide Association Studies (GWAS). CDGs are extremely rare and often with severe medical consequences. In contrast, GWAS are likely to identify more common genetic variations and generally involve less severe and distinct traits. We recently confirmed that structural defects in GTf genes are extremely rare, which seemed at odds with the large number of GWAS pointing to GTf-genes. To resolve this issue, we surveyed the GTf-genome for reported CDGs and GWAS candidates; we found little overlap between the two groups of genes. Moreover, GTf-genes implicated by CDG or GWAS appear to constitute different classes with respect to their: (i) predicted roles in glycosylation pathways; (ii) potential for partial redundancy by closely homologous genes; and (iii) transcriptional regulation as evaluated by RNAseq data. Our analysis suggest that more complex traits are caused by dysregulation rather than structural deficiency of GTfs, which suggests that some glycosylation reactions may be predicted to be under tight regulation for fine-tuning of important biological functions. PMID- 29579193 TI - Divide and conquer: improving parental understanding of health-related instructions using sequential pictorial instructions. AB - Patient misunderstandings of healthcare-related instructions result in significant health, social and economic consequences. Pushing the boundaries of traditional academic methods may offer strategies that promote new ways to improve communication and understanding between healthcare providers, caregivers and patients. Comics can be an educational tool, offering an innovative strategy to communicate health-related information. Our study objective was to compare parents' understanding of health-related instructions (i.e. prescription labels, medical instructions and emergency situation scenarios) that were presented using two different formats-sequential pictorial instructions (SPIs) versus written text instructions (WRIs).This was a cross-sectional study to compare parents' understanding of health-related instructions for pediatric patients using structured SPIs versus WRIs. Parents (n = 359, 18-82 years old) of pediatric patients were given a card with instructions that were presented as SPIs (n = 195, 54.3%) or WRIs (n = 164, 45.7%), and then they completed a questionnaire. Total (14 questions) and grouped scores (10 questions) for parental comprehension of prescription and medical emergency instructions were significantly higher among participants viewing the SPIs than those viewing the WRIs in both English and Spanish. The mean understanding of instructions significantly increased from 6% to 12.2% when comparing the WRI versus the SPI.Our initial findings indicate that parents and caregivers of pediatric patients had significantly better understanding and recall of instructions delivered using SPIs than using WRIs. PMID- 29579194 TI - Using social norms theory for health promotion in low-income countries. AB - Social norms can greatly influence people's health-related choices and behaviours. In the last few years, scholars and practitioners working in low- and mid-income countries (LMIC) have increasingly been trying to harness the influence of social norms to improve people's health globally. However, the literature informing social norm interventions in LMIC lacks a framework to understand how norms interact with other factors that sustain harmful practices and behaviours. This gap has led to short-sighted interventions that target social norms exclusively without a wider awareness of how other institutional, material, individual and social factors affect the harmful practice. Emphasizing norms to the exclusion of other factors might ultimately discredit norms-based strategies, not because they are flawed but because they alone are not sufficient to shift behaviour. In this paper, we share a framework (already adopted by some practitioners) that locates norm-based strategies within the wider array of factors that must be considered when designing prevention programmes in LMIC. PMID- 29579196 TI - Safety and efficacy of delivering high-power short-duration radiofrequency ablation lesions utilizing a novel temperature sensing technology. AB - Aims: Delivery of high-power short-duration radiofrequency (RF) ablation lesions is not commonly used, in part because conventional thermocouple (TC) technology underestimates tissue temperature, increasing the risk of steam pop, and thrombus formation. We aimed to test whether utilization of an ablation catheter equipped with a highly accurate novel TC technology could facilitate safe and effective delivery of high-power RF lesions. Methods and results: Adult male Yorkshire swine were used for the study. High-power short-duration ablations (10-s total; 90 W for 4 s followed by 50 W for 6 s) were delivered using an irrigated force sensing catheter, equipped with six miniature TC sensors embedded in the tip electrode shell. Power modulation was automatically performed when the temperature reached 65 degrees C. Ablation parameters were recorded and histopathological analysis was performed to assess lesion formation. One hundred and fourteen RF applications, delivered using the study ablation protocol in the ventricles of eight swine [53 in the right ventricle (RV), 61 in the left ventricle (LV)], were analysed. Average power delivered was 55.4 +/- 5.3 W and none of the ablations resulted in a steam pop. Fourteen out of the 114 (12.3%) lesions were transmural. The mean lesion depth was 3.9 +/- 1.1 mm for the 100 non transmural lesions. Similar ablation parameters resulted in bigger impedance drop (11.6 Omega vs. 9.1 Omega, P = 0.009) and deeper lesions in the LV compared with the RV (4.3 +/- 1.2 mm vs. 3.3 +/- 0.8 mm, P < 0.001). Conclusion: Delivery of high-power short-duration RF energy applications, facilitated by a novel ablation catheter system equipped with advanced TC technology, is feasible, safe, and results in the formation of effective ablation lesions. PMID- 29579195 TI - Negligible Impact of Mass Screening and Treatment on Mesoendemic Malaria Transmission at West Timor in Eastern Indonesia: A Cluster-Randomized Trial. AB - Background: Mass screening and treatment (MST) aims to reduce malaria risk in communities by identifying and treating infected persons without regard to illness. Methods: A cluster-randomized trial evaluated malaria incidence with and without MST. Clusters were randomized to 3, 2, or no MST interventions: MST3, 6 clusters (156 households/670 individuals); MST2, 5 clusters (89 households/423 individuals); and MST0, 5 clusters (174 households/777 individuals). All clusters completed the study with 14 residents withdrawing. In a cohort of 324 schoolchildren (MST3, n = 124; MST2, n = 57; MST0, n = 143) negative by microscopy at enrollment, we evaluated the incidence density of malaria during 3 months of MST and 3 months following. The MST intervention involved community wide expert malaria microscopic screening and standard therapy with dihydroartemisinin-piperaquine and primaquine for glucose-6 phosphate dehydrogenase-normal subjects. All blood examinations included polymerase chain reaction assays, which did not guide on-site treatment. Results: The risk ratios for incidence density of microscopically patent malaria in MST3 or MST2 relative to that in MST0 clusters were 1.00 (95% confidence interval [CI], .53-1.91) and 1.22 (95% CI, .42-3.55), respectively. Similar results were obtained with molecular analysis and species-specific (P. falciparum and P. vivax) infections. Microscopically subpatent, untreated infections accounted for 72% of those infected. Conclusions: Two or 3 rounds of MST within 3 months did not impact the force of anopheline mosquito-borne infection in these communities. The high rate of untreated microscopically subpatent infections likely explains the observed poor impact. Clinical Trials Registration: NCT01878357.

PMID- 29579198 TI - A comprehensive evaluation of alignment software for reduced representation bisulfite sequencing data. AB - Motivation: The rapid development of next-generation sequencing technology provides an opportunity to study genome-wide DNA methylation at single-base resolution. However, depletion of unmethylated cytosines brings challenges for aligning bisulfite-converted sequencing reads to a large reference. Software tools for aligning methylation reads have not yet been comprehensively evaluated, especially for the widely used reduced representation bisulfite sequencing (RRBS) that involves enrichment for CpG islands (CGIs). Results: We specially developed a simulator, RRBSsim, for benchmarking analysis of RRBS data. We performed extensive comparison of seven mapping algorithms for methylation analysis in both real and simulated RRBS data. Eighteen lung tumors and matched adjacent tissues were sequenced by the RRBS protocols. Our empirical evaluation found that methylation results were less consistent between software tools for CpG sites with low sequencing depth, medium methylation level, on CGI shores or gene body. These observations were further confirmed by simulations that indicated software tools generally had lower recall of detecting these vulnerable CpG sites and lower precision of estimating methylation levels in these CpG sites. Among the software tools tested, bwa-meth and BS-Seeker2 (bowtie2) are currently our preferred aligners for RRBS data in terms of recall, precision and speed. Existing aligners cannot efficiently handle moderately methylated CpG sites and those CpG sites on CGI shores or gene body. Interpretation of methylation results from these vulnerable CpG sites should be treated with caution. Our study reveals several important features inherent in methylation data, and RRBSsim provides guidance to advance sequence-based methylation data analysis and methodological development. Availability and implementation: RRBSsim is a simulator for benchmarking analysis of RRBS data and its source code is available at https://github.com/xwBio/RRBSsim or https://github.com/xwBio/Docker-RRBSsim.

PMID- 29579200 TI - Mechanical dyssynchrony of the left atrium during sinus rhythm is associated with history of stroke in patients with atrial fibrillation. AB - Aims: We sought to evaluate the relationship between left atrial (LA) mechanical dyssynchrony and history of stroke or transient ischaemic attack (TIA) in patients with atrial fibrillation (AF). We hypothesized that mechanical dyssynchrony of the LA is associated with history of stroke/TIA independent of LA function and Cardiac failure, Hypertension, Age, Diabetes, Stroke/transient ischaemic attack (TIA), VAscular disease, and Sex category (CHA2DS2-VASc) score in patients with AF. Methods and results: We conducted a cross-sectional study of 246 patients with a history of AF (59 +/- 10 years, 29% female, 26% non paroxysmal AF) referred for catheter ablation to treat drug-refractory AF who underwent preablation cardiac magnetic resonance (CMR) in sinus rhythm. Using tissue-tracking CMR, we measured the LA longitudinal strain and strain rate in each of 12 equal-length segments in two- and four-chamber views. We defined indices of LA mechanical dyssynchrony, including the standard deviation of the time to the peak longitudinal strain (SD-TPS). Patients with a prior history of stroke or TIA (n = 23) had significantly higher SD-TPS than those without (n = 223) (39.9 vs. 23.4 ms, P < 0.001). Multivariable analysis showed that SD-TPS was associated with stroke/TIA after adjusting for the CHA2DS2-VASc score, LA minimum index volume, and the peak LA longitudinal strain (P < 0.001). The receiver operating characteristics curve showed that SD-TPS identified patients with stroke/TIA more accurately than CHA2DS2-VASc score alone (c-statistics: 0.82 vs. 0.75, P < 0.001). Conclusion: Higher mechanical dyssynchrony of the LA during sinus rhythm is associated with a history of stroke/TIA in patients with AF. PMID- 29579201 TI - Intramacrophage Mycobacterium tuberculosis efflux pump gene regulation after rifampicin and verapamil exposure. AB - Objectives: Since resistance of Mycobacterium tuberculosis (Mtb) partially derives from efflux pumps (EPs) in the plasma membrane, the current study evaluates EPs in Mtb exposed to rifampicin in the presence of the EP inhibitor verapamil, within a macrophage environment. Methods: Human acute monocytic leukaemia cell line THP-1 was infected with Mtb H37Rv and exposed to rifampicin and verapamil alone and in combination for 24 and 72 h. After RNA extraction, quantitative PCR was carried out for 11 EP genes using SYBR green PCR master mix in the StepOneTM Real-Time PCR System. Results: After 24 h of exposure to rifampicin, Mtb H37Rv showed that 10 EP genes were up-regulated when compared with the control. The rifampicin/verapamil combination induced down-regulation of 54.5% (6/11) of the EP genes. At 72 h, rifampicin exposure induced up-regulation of 10 EP genes and rifampicin/verapamil induced down-regulation of 8 EP genes, which suggests effective EP-inhibitory activity of verapamil against Mtb H37Rv in an intramacrophage environment. Conclusions: The current study demonstrated that rifampicin/verapamil caused down-regulation of several EP genes in Mtb inside the macrophage environment. In vivo trials may show that rifampicin/verapamil therapy could be of value in enhancing anti-TB treatment. PMID- 29579203 TI - Reorienting Norwegian mental healthcare services: listen to patients' learning appetite. AB - Reorientation of healthcare services towards more efficient health promotion interventions is an urgent matter. Despite policies and guidelines being in place, it is the least developed key action area of the Ottawa charter. User involvement, or the voice of the patient, is missing from the knowledge base of health promotion in the mental healthcare services. The aim of this study was to add experiential knowledge from former patients. We explored the lived experience of 12 former inpatients at a mental healthcare hospital. We describe what they perceive as mental health promoting efforts. A salutogenic theoretical framework and the methodology of interpretative phenomenological analysis were used. The analysis revealed an appetite for learning in order to develop an in depth understanding of their former experiences. This was motivated by a desire to master daily life despite living with an illness and to increase health and well being. The participants perceived the learning processes within the healthcare setting as mental health promoting. This craving for a better life is compatible with health promotion. It may turn out to be an opportunity to complement the curative activity of healthcare services with health promotion educational activities. PMID- 29579202 TI - Predictors of exclusive breastfeeding across three time points in Bangladesh: an examination of the 2007, 2011 and 2014 Demographic and Health Survey. AB - Background: The objective of this study was to explore predictors of exclusive breastfeeding (EBF) in Bangladesh using data from 2007, 2011 and 2014, specifically focusing on potential reasons why rates of EBF changed over those time periods. Methods: Data on mother/infant pairs with infants <6 months of age were examined at the three time points using the Bangladesh Demographic and Health Survey. The EBF prevalence, changes in EBF since the previous survey and determinants of EBF at each time period were examined using t-tests, chi2 and multilevel logistic regression. Results: The prevalence of EBF was 42.5, 65 and 59.4% in 2007, 2011 and 2014, respectively. The age of the child was significantly associated with EBF across all time points. The largest changes in EBF occurred in the 3- to 5-month age group. Predictors of EBF in this specific age group were similar to overall predictors (e.g. age of the child and region). Participation of the mother in household decisions was a significant predictor in 2014. Conclusions: EBF prevalence in Bangladesh increased between 2007 and 2011 and then decreased between 2011 and 2014. The increase in 2011 may have been the result of widespread initiatives to promote EBF in that time frame. Due to the unexplained decrease in EBF between 2011 and 2014, there is still a need for interventions such as peer counselling, antenatal education and community awareness to promote EBF. PMID- 29579204 TI - Dietary diversity and nutritional status among children in rural Burkina Faso. AB - Background: Burkina Faso has a seasonal malnutrition pattern, with higher malnutrition prevalence during the rainy season when crop yields are low. We investigated the association between dietary diversity and nutritional status among children aged 6-59 mo during the low crop yield season in rural Burkina Faso to assess the role of dietary diversity during the lean season on childhood nutritional status. Methods: Caregivers reported the dietary diversity of the past 7 d, consisting of 11 food groups, summed into a scale. Anthropometric measurements were taken from all children. Height-for-age (HAZ), weight-for height (WHZ) and weight-for-age (WAZ) z-scores were calculated based on 2006 WHO standards. Stunting, wasting and underweight were defined as HAZ, WHZ and WAZ <-2 SD, respectively. Multivariable regression models adjusting for potential confounders including household food insecurity and animal ownership were used to assess the relationship between anthropometric indices and dietary diversity. Results: Of 251 children enrolled in the study, 20.6% were stunted, 10.0% wasted and 13.9% underweight. Greater dietary diversity was associated with greater HAZ (SD 0.14, 95% CI 0.04 to 0.25) among all children. There was no association between dietary diversity and wasting or mid-upper arm circumference in this study. Conclusions: Increasing dietary diversity may be an approach to reduce the burden of stunting and chronic malnutrition among young children in regions with seasonal food insecurity. PMID- 29579206 TI - An miR-200 Cluster on Chromosome 23 Regulates Sperm Motility in Zebrafish. AB - Besides its well-documented roles in cell proliferation, apoptosis, and carcinogenesis, the function of the p53-microRNA axis has been recently revealed in the reproductive system. Recent studies indicated that miR-200 family members are dysregulated in nonobstructive azoospermia patients, whereas their functions remain poorly documented. The aim of this study was to investigate the function of the miR-200 family on zebrafish testis development and sperm activity. There was no substantial difference in testis morphology and histology between wild type (WT) and knockout zebrafish with deletion of miR-200 cluster on chromosome 6 (chr6-miR-200-KO) or on chromosome 23 (chr23-miR-200-KO). Interestingly, compared with WT zebrafish, the chr6-miR-200-KO zebrafish had no difference on sperm motility, whereas chr23-miR-200-KO zebrafish showed significantly improved sperm motility. Consistently, ectopic expression of miR-429a, miR-200a, and miR-200b, which are located in the miR-200 cluster on chromosome 23, significantly reduced motility traits of sperm. Several sperm motility-related genes, such as amh, wt1a, and srd5a2b have been confirmed as direct targets of miR-200s on chr23. 17alpha-ethynylestradiol (EE2) exposure resulted in upregulated expression of p53 and miR-429a in testis and impairment of sperm motility. Strikingly, in p53 mutant zebrafish testis, the expression levels of miR-200s on chr23 were significantly reduced and accompanied by a stimulation of sperm motility. Moreover, the upregulation of miR-429a associated with EE2 treatment was abolished in testis with p53 mutation. And the impairment of sperm activity by EE2 treatment was also eliminated when p53 was mutated. Together, our results reveal that miR-200 cluster on chromosome 23 controls sperm motility in a p53 dependent manner. PMID- 29579205 TI - Effect of Tea Saponin-Treated Host Plants on Activities of Antioxidant Enzymes in Larvae of the Diamondback Moth Plutella xylostella (Lepidoptera: Plutellidae). AB - Tea saponin (TS) is extracted from the seeds of the tea plant and is generally regarded as a safe compound that has insecticidal properties and can act synergistically with other compounds. In this study, the activities of antioxidant enzymes superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and the levels of malondialdehyde (MDA) were compared in midgut tissues of third instar larvae of the diamondback moth (DBM), Plutella xylostella L. (Lepidoptera: Plutellidae). The larvae were fed on three different host plants, cabbage (Brassica oleracea L. var. capitata [Capparales: Brassicaceae]), radish (Raphanus sativus L. var. radiculus Persi [Capparales: Brassicaceae]), or rape (Brassica campestris L. [Capparales: Brassicaceae]), that had been treated with TS. Higher SOD, POD, and CAT activities were found in DBM larvae fed on cabbage after LC20 (concentration that induced 20% larval mortality) or LC50 (concentration that induced 50% larval mortality) treatment than on the control. On rape, TS treatments led to lower SOD and CAT activities than in the control and to higher POD activities after 24 h. MDA content increased in larvae fed on rape but decreased in larvae fed on radish after 12 h. Our results indicated that DBM larvae are more susceptible to TS on rape than on cabbage and radish, suggesting that this treatment may be an economic and effective means of controlling DBM on rape. PMID- 29579207 TI - Implementation of a human papillomavirus screen-and-treat model in Mwanza, Tanzania: training local healthcare workers for sustainable impact. AB - Background: The purpose of this study is to evaluate the development of a 1-wk screening campaign and efforts towards the implementation of a sustainable system that addresses cervical cancer in Mwanza, Tanzania with a screen-and-treat model utilizing visual inspection of the cervix with acetic acid (VIA) and cryotherapy. Methods: In partnership with CureCervicalCancer (CCC), a non-profit organization based in Los Angeles, CA, USA, 11 medical students at the University of California, Irvine School of Medicine established a model for sustainable human papillomavirus screening practices in Mwanza, Tanzania. This study both quantitatively and qualitatively assesses the successes and limitations of the program model. Results: During the 5-day training, a total of 614 women attended the screenings and 556 women were screened with VIA, of whom 10.6% (n=59) were VIA positive and 89.4% (n=499) were VIA negative. Of those who were VIA positive, 83.1% (n=49) received cryotherapy while 16.9% (n=10) did not due to suspicion of advanced cancer (n=7), refusal to receive cryotherapy (n=2) or pregnancy (n=1). Conclusions: The screen-and-treat model for the identification and treatment of precancerous cervical lesions is an effective public health intervention with the potential to impact women by providing the tools and education needed by local healthcare professionals. However, limitations common to resource-poor settings, such as continuity of funding, loss to follow-up and transportation costs, remain barriers to sustainability. PMID- 29579208 TI - Earthworms are associated with subpopulations of Gammaproteobacteria irrespective of the total soil microbiota composition and stability. AB - Soil represents one of the most complex microbial ecosystems on earth. It is well known that invertebrates such as earthworms have a major impact on transformations of organic material in soil, while their effect on the soil microbiota remains largely unknown. The aim of our work was therefore to investigate the association of earthworms with temporal stability, composition and diversity in two soil microbiota experimental series. We found that earthworms were consistently associated with an increase in subgroups of Gammaproteobacteria, despite major differences in microbiota composition and temporal stability across the experimental series. Our results therefore suggest that earthworms can affect subpopulation dynamics in the soil microbiota, irrespective of the total microbiota composition. If the soil microbiota is comprised of independent microbiota components, this can contribute to our general understanding of the complexity of the soil microbiota. PMID- 29579210 TI - Changes in prescription pattern, pharmaceutical expenditure and quality of care after introduction of reimbursement restriction in diabetes in Korea. AB - Background: To ensure effective prescription practices and reduce diabetes related pharmaceutical expenditures, Korea adopted a clinical practice guideline for the reimbursement system. Health care providers cannot receive reimbursement from National Health Insurance(NHI) unless it is for an appropriate prescription under the predefined clinical condition. The aim of this study was to evaluate prescription patterns in oral hypoglycemic agents, costs and effects on patient care since the introduction of the diabetes reimbursement restriction. Methods: We used claim data from 2008 to 2013, which included 26 315 diabetes patients and 9907 hospitals. An interrupted time series study design using generalized estimating equations was used to evaluate changes in patterns of single and combination therapy, brand name drug prescriptions, cost and hospital admission following the reimbursement restriction. Results: Following reimbursement restriction initiation, we found a statistically significant decrease in the average prescription rate of brand name drugs (-6.2%), whereas single therapy prescription increased (9.9%). There was also a reduction in trend change in the monthly prescription rate for combination therapy (-1.7%) and brand name drugs ( 0.8%). For single therapy, the trend change in prescription rate increased after the intervention (0.8%). A reduction of trend change in pharmaceutical costs ( 0.3%) was observed. However, we did not find a significant change in hospital admission for diabetes. Conclusions: Reimbursement restriction affects both pharmaceutical costs and physicians' decisions to prescribe oral hypoglycemic agents. We did not observe a significant reduction in quality of care following the intervention. Collectively, these findings indicate that reimbursement restriction has improved effective drug utilization and decreased health expenditures. PMID- 29579209 TI - Does minimally invasive coronary artery bypass improve outcomes compared to off pump coronary bypass via sternotomy in patients undergoing coronary artery bypass grafting? AB - A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'In patients undergoing off-pump coronary artery bypass grafting, for single or multivessel disease, does minimally invasive direct coronary artery bypass (MIDCAB) or off-pump coronary artery bypass (OPCAB) provide the superior outcome including a reduction in morbidity and mortality?'. A total of 187 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. The authors, date, journal and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. It was found that compared to OPCAB, MIDCAB surgery can offer decreased intensive care unit length of stay (4.5-57.4 h vs 5.2-52.7 h) and total hospital length of stay (4.5 8.5 days vs 5.2-12 days), with 1 paper showing a decrease in mortality at 1 year (3% vs 14%). However, there were several papers that showed significant risks with MIDCAB surgery in patients with either single or multivessel disease. These include increased risk of incomplete revascularization (29% vs 0%), significant early complications (22.5 vs 0%), urgent reintervention (16% vs 0%), repeat revascularization events (12.2% vs 3.7%), progression of native disease (4.8% vs 0.9%), rehospitalization by 3 months (20% vs 2%) and postoperative infarction (2.9% vs 1.45%). These risks did not translate to an increase in early mortality (0-1% vs 0-1.6%) or late mortality (0-3% vs 0-14%) in papers that included mid term follow up. However, they do represent significant potential risks that cannot be overlooked when considering the use of MIDCAB. We conclude that MIDCAB is associated with greater morbidity and reintervention compared to OPCAB via sternotomy, but both techniques are equivalent in terms of operative and mid-term mortality.

PMID- 29579213 TI - Global aspects of viral glycosylation. AB - Enveloped viruses encompass some of the most common human pathogens causing infections of different severity, ranging from no or very few symptoms to lethal disease as seen with the viral hemorrhagic fevers. All enveloped viruses possess an envelope membrane derived from the host cell, modified with often heavily glycosylated virally encoded glycoproteins important for infectivity, viral particle formation and immune evasion. While N-linked glycosylation of viral envelope proteins is well characterized with respect to location, structure and site occupancy, information on mucin-type O-glycosylation of these proteins is less comprehensive. Studies on viral glycosylation are often limited to analysis of recombinant proteins that in most cases are produced in cell lines with a glycosylation capacity different from the capacity of the host cells. The glycosylation pattern of the produced recombinant glycoproteins might therefore be different from the pattern on native viral proteins. In this review, we provide a historical perspective on analysis of viral glycosylation, and summarize known roles of glycans in the biology of enveloped human viruses. In addition, we describe how to overcome the analytical limitations by using a global approach based on mass spectrometry to identify viral O-glycosylation in virus-infected cell lysates using the complex enveloped virus herpes simplex virus type 1 as a model. We underscore that glycans often pay important contributions to overall protein structure, function and immune recognition, and that glycans represent a crucial determinant for vaccine design. High throughput analysis of glycosylation on relevant glycoprotein formulations, as well as data compilation and sharing is therefore important to identify consensus glycosylation patterns for translational applications.

AB - Objectives: To develop a population model describing temocillin pharmacokinetics (PK) in patients undergoing haemodialysis and investigate how pharmacokinetic/pharmacodynamic (PD) targets can be met with different dosage regimens. Patients and methods: Sixteen patients received the currently licenced dosing of 1, 2 or 3 g of temocillin (total of 61 doses) corresponding to an inter dialytic period of 20, 44 or 68 h, respectively, and a dialysis period of 4 h. A non-linear mixed-effects model was developed jointly for total and unbound temocillin serum concentrations. The performance of clinically feasible dosing regimens was evaluated using a 5000-subject Monte Carlo (MC) simulation for determining the highest MIC for which the PK/PD target of 40%fT>MIC would be reached in 90% of patients [probability of target attainment (PTA)]. This PK study was registered at ClinicalTrials.gov (NCT02285075). Results: Temocillin unbound and total serum concentrations (429 samples) were used to fit an open two compartment model with non-linear albumin binding and first-order elimination. In addition to total body clearance, dialysis clearance was modelled using the Michaels function. The currently licenced dosing achieved a 90% PTA for an MIC up to 8 mg/L. A new temocillin dosage regimen was designed that would achieve a 90% PTA for an MIC of 16 mg/L (MIC90 of target organisms) adjusted to patient weight and inter-dialytic period. Conclusions: Currently licensed dosage regimen is suboptimal for MICs >8 mg/L (frequently found in clinical isolates). Model-based simulations allowed suggestion of a new dosage regimen with improved probability of microbiological success, applicability in routine clinical practice and more appropriate for empirical therapy.

AB - There are multiple forms of interactions between termites and bacteria. In addition to their gut microbiota, which has been intensively studied, termites host intracellular symbionts such as Wolbachia. These distinct symbioses have been so far approached independently and mostly in adult termites. We addressed the dynamics of Wolbachia and the microbiota of the eggs and gut for various life stages and castes of the wood-feeding termite, Nasutitermes arborum, using deep sequencing of the 16S rRNA gene. Wolbachia was dominant in eggs as expected. Unexpectedly, it persisted in the gut of nearly all stages and castes, indicating a wide somatic distribution in termites. Wolbachia-related sequences clustered into few operational taxonomic units, but these were within the same genotype, acquired maternally. Wolbachia was largely dominant in DNA extracts from the guts of larvae and pre-soldiers (59.1%-99.1% of reads) where gut-resident lineages were less represented and less diverse. The reverse was true for the adult castes. This is the first study reporting the age-dependency of the relative abundance of Wolbachia in the termite gut and its negative correlation with the diversity of the microbiota. The possible mechanisms underlying this negative interaction are discussed. PMID- 29579216 TI - Acinetobacter baumannii Resistance Trends in Children in the United States, 1999 2012. AB - Background: Acinetobacter baumannii is a common cause of healthcare-associated infections. Carbapenem-resistant (CR) A baumannii is a significant threat globally. We used a large reference laboratory database to study the epidemiology of A baumannii in children in the United States. Methods: Antimicrobial susceptibility data from The Surveillance Network were used to phenotypically identify antibiotic resistance in A baumannii isolates in children 1-17 years of age between January 1999 and July 2012. Logistic regression analysis was used to calculate trends in the prevalence of antibiotic resistance in A baumannii. Isolates from infants (<1 year old) were excluded. Results: The crude proportion of cephalosporin-resistant (CephR) A baumannii increased from 13.2% in 1999 to 23.4% in 2012 with a peak of 32.5% in 2008, and the proportion of CR A baumannii increased from 0.6% in 1999 to 6.1% in 2012 with a peak of 12.7% in 2008. From 1999 to 2012, the proportion of CephR and CR A baumannii increased each year by 3% and 8%, respectively (CephR odds ratio [OR] = 1.03, 95% confidence interval [CI], 1.01-1.04; CR OR = 1.08, 95% CI, 1.05-1.12); however, after 2008, a significant decrease in trend was observed (CephR OR = 0.78, 95% CI, 0.71-0.87; CR OR = 0.73, 95% CI, 0.62-0.86), but resistance remained higher than baseline (1999). Conclusions: Overall, between 1999 and 2012, CephR and CR A baumannii isolates increased in children; however, a decreasing trend was observed after 2008.There is a need for ongoing surveillance of A baumannii infections and continued assessment of effective prevention strategies in vulnerable populations. PMID- 29579217 TI - Nursing and Hospital Abortions in the United States, 1967-1973. AB - Before elective abortion was legalized nationally in 1973 with the U.S. Supreme Court decision Roe v. Wade, seventeen states and the District of Columbia liberalized their abortion statutes. While scholars have examined the history of physicians who had performed abortions before and after it was legal and of feminists' work to expand the range of healthcare choices available to women, we know relatively little about nurses' work with abortion. By focusing on the history of nursing in those states that liberalized their abortion laws before Roe, this article reveals how women who sought greater control over their lives by choosing abortion encountered medical professionals who were only just beginning to question the gendered conventions that framed labor roles in American hospitals. Nurses, whose workloads increased exponentially when abortion laws were liberalized, were rarely given sufficient training to care for abortion patients. Many nurses directed their frustrations to the women patients who sought the procedure. This essay considers how the expansion of women's right to abortion prompted nurses to question the gendered conventions that had shaped their work experiences.

AB - Background: Determinants of hypertension diagnosis and/or awareness and control among older adults are understudied in Albania, a former communist country in South Eastern Europe, which is experiencing rapid demographic, socioeconomic and epidemiological transition. This paper examines the association of individual, interpersonal, organizational and community factors with hypertension awareness and control among older adults in Tirana, the Albanian capital. Methods: Using 2012 International Mobility in Aging Study data on older adults from Albania's capital city (n = 393) and the socioecological model as a conceptual framework, multinomial regression models identified factors associated with controlled, uncontrolled and undiagnosed hypertension. Results: For hypertension, 17.3% participants had none, 23.4% were controlled, 48.4% were uncontrolled and 10.9% were undiagnosed/unaware. Compared to those with controlled hypertension, in multivariable models, a high level of friend support was negatively associated with uncontrolled (OR: 0.4; 95% CI: 0.2-0.9) and undiagnosed (OR: 0.2; 95% CI: 0.1-0.6) hypertension. A high level of perceived neighbourhood safety was negatively associated with uncontrolled (OR: 0.6; 95% CI: 0.3-1.0) and undiagnosed (OR: 0.4; 95% CI: 0.2-1.0) hypertension. Compared to those with no hypertension, children's social support was positively associated with uncontrolled (OR: 2.2; 95% CI: 1.1-4.3) and undiagnosed (OR: 3.6; 95% CI: 1.3 9.6) hypertension. Conclusion: This study provides new insights about distinct risk factors for inadequate hypertension management in Albania. It highlights the importance of community-level factors (safety) and interpersonal factors (family and friend ties) to hypertension diagnosis/awareness and control, which may provide novel intervention opportunities for hypertension programs. PMID- 29579219 TI - Operator volume is not associated with mortality following percutaneous coronary intervention: insights from the British Cardiovascular Intervention Society registry. AB - Aims: The relationship between operator volume and outcomes for percutaneous coronary intervention (PCI) has been studied in the past, but recent analyses of national data covering the modern radial, acute coronary syndrome-dominant era are limited. Changing in case-mix, practice, and service provision mean that previously described volume-outcome relationships may no longer be relevant, and a reassessment in contemporary practice is needed. We aim to assess whether operator volume is associated with independently reported 30-day mortality in a contemporary PCI cohort. Methods and results: This observational cohort study analysed procedures recorded in the British Cardiovascular Intervention Society PCI database from 2013 to 2014 in England and Wales. Mixed effects multiple logistic regression modelling was used to account for operator and centre level effects and to adjust for potential confounders. Volume is defined as the total number of procedures the operator was responsible for in the previous 12 months. A total of 133 970 procedures were analysed. Median volume across all procedures was 178 per year (interquartile range 128-239). The 30-day mortality rate was 2.6%. After adjustment for case-mix, the association between volume and mortality was negligible (odds ratio per 100 procedures 0.99, 95% confidence interval 0.93 1.05; P = 0.725). Sensitivity analyses showed similar results amongst high-risk PCI subsets and in-hospital outcomes. Conclusion: There is no evidence that mortality differs by operator volume in the UK. Volume-outcome relationships in PCI should be carefully monitored in response to future changes in practice. PMID- 29579220 TI - Insufficient physical activity in combination with high screen time is associated with adolescents' psychosocial difficulties. AB - Background: Although screen time (ST) and insufficient physical activity (PA) are fairly common among adolescents, it is unclear whether these conditions are jointly associated with adolescents' psychosocial difficulties. This study aimed to examine interactive associations of ST and PA with psychosocial difficulties among adolescents in Bangladesh. Methods: Data were from 671 students (ages 13-16 y) from eight secondary schools of Dhaka City, Bangladesh. Recreational ST was assessed using the Adolescent Sedentary Activity Questionnaire. The 3-day Physical Activity Recall instrument was used to estimate PA. Psychosocial difficulty was measured using the parent version of the Strengths and Difficulties Questionnaire (SDQ). Results: Sixteen percent of the adolescents had high SDQ total difficulties scores (>=17) and another 14% had moderate scores (14 16; borderline). Multivariable modelling showed that adolescents with high ST (>2 h/day) and insufficient PA (<60 min/day; not meeting the PA recommendation) had more psychosocial difficulties than their counterparts who had low ST and met PA recommendations (p=0.03). The analysis also found marginal evidence (p=0.06) of an association with psychosocial difficulties for adolescents with insufficient PA and low ST. Conclusions: Adolescents in Dhaka City who have high recreational ST and are not meeting PA recommendations are likely to also have psychosocial difficulties. Longitudinal studies are needed to understand the causal relationships between these variables. PMID- 29579221 TI - Prolonged dialysis duration is associated with graft failure and mortality after kidney transplantation: results from the French transplant database. AB - Background: Kidney transplantation (KT) is the treatment of choice for end-stage renal disease. Preemptive KT (PKT) should be considered when glomerular filtration rate is <15 mL/min/1.73 m2 but European reports on the results of PKT and the effect of pretransplant dialysis are scarce. Methods: We analysed all first kidney-only transplants performed in adults in France between 2002 and 2012. A Cox multivariable model was used to investigate the association of PKT and of pretransplant dialysis time with the hazard of graft failure defined as death, return to dialysis or retransplant, whichever occurred first. Results: We included 22 345 patients, with a mean +/- SD age at KT of 50.5 +/- 13.4 years; 61.9% were men and 3112 (14.0%) received a PKT. Median time of follow-up was 4.7 years. Graft failure occurred in 4952 patients up to 31 December 2013. After adjustment for recipients' age and sex, primary kidney disease, donor type (living or deceased donor, expanded criteria donor), HLA mismatches, cold ischaemia time, centre and year of transplantation, PKT was associated with a decreased hazard of graft failure when compared with pretransplant dialysis [hazard ratio (HR) 0.57; 95% confidence interval (CI) 0.51-0.63], whatever the duration of dialysis, even in the first 6 months. The effect of PKT on the hazard of graft failure was stronger in living kidney donors (HR 0.32; 95% CI 0.19 0.55). Conclusions: In France, PKT was associated with a lower risk of graft failure than KT performed after the initiation of dialysis, whatever the duration of dialysis. PMID- 29579223 TI - Assessment of a congenital heart surgery programme: a reappraisal. AB - OBJECTIVES: To assess our practice according to the Society of Thoracic Surgeons and the European Association for Cardio-Thoracic Surgery (STS-EACTS) Mortality Score and to the new concept of unit performance. METHODS: All main procedures carried out in the years 2012-2016 were analysed. The STS-EACTS model-based mortality risk procedure was used to calculate expected mortality. Surgical performance was estimated as the Aristotle complexity score multiplied by hospital survival. Unit performance was defined as surgical performance multiplied by the number of procedures. RESULTS: In total, 2435 procedures were analysed. One hundred and two deaths (95% confidence interval 71-135 deaths) were expected; 43 patients died after operation. Observed mortality divided by expected mortality was 0.42. The ratio ranged from 0.23 (year 2014) to 0.59 (year 2013) and was <0.6 in all STS-EACTS mortality categories. The difference between observed and expected mortality was highly significant: 1.8% vs 4.2% (P-value <0.0001). Observed surgical and unit performances were, higher than expected performances every year. Achieved surgical performance was the highest in year 2012 (7.28 +/- 2.54) and the lowest in year 2014 (7.04 +/- 2.52). The highest figure of unit performance was achieved in year 2016: 3980 points. CONCLUSIONS: The STS-EACTS score, currently recognized as a sound instrument to assess mortality after congenital heart surgery, overestimated postoperative mortality. If these results are confirmed by other centres, the model should be recalibrated to match the current surgical practice. Although surgical performance can evaluate outcome quality, it does not include case volume activity. Unit performance provides this information, and it integrates quality and quantity into a single value. PMID- 29579222 TI - Inhibition of fatty acid amide hydrolase by PF-3845 alleviates the nitrergic and proinflammatory response in rat hippocampus following acute stress. AB - Background: Long term exposure to stress has been demonstrated to cause neuroinflammation through a sustained overproduction of free radicals, including nitric oxide, via an increased inducible nitric oxide synthase (iNOS) activity. We have previously demonstrated that iNOS activity and mRNA are significantly upregulated in the rat hippocampus following just 4 hours of restraint stress. Similar to nitric oxide, endocannabinoids are synthesised on demand, with preclinical observations suggesting that cannabinoid receptor agonists and endocannabinoid enhancers inhibit nitrergic activity. Specifically, previous work has shown that enhancement of endocannabinoids via inhibition of fatty acid amide hydrolase with PF-3845 reduced iNOS-expressing microglia following traumatic brain injury. However, this describes cannabinoid modulation following physical injury and therefore the present study aimed to examine the effects of PF-3845 in the modulation of nitrergic and inflammatory-related genes within the hippocampus after acute stress exposure. Methods: Following vehicle or PF-3845 injections (5 mg/kg; i.p.), male Wistar rats were exposed to 0 (control), 60, 240, or 360 minutes of restraint stress after which plasma and dorsal hippocampus were isolated for further biochemical and gene expression analysis. Results: The results demonstrate that pre-treatment with PF-3845 rapidly ameliorates plasma corticosterone release at 60 minutes of stress. An increase in endocannabinoid signalling also induces an overall attenuation in iNOS, tumor necrosis factor alpha convertase, interleukin-6, cyclooxygenase-2, peroxisome proliferator activated receptor gamma mRNA, and the transactivation potential of NF-kappaB in the hippocampus. Conclusions: These results suggest that enhanced endocannabinoid levels in the dorsal hippocampus have an overall anti-nitrosative and anti inflammatory effect following acute stress exposure. PMID- 29579224 TI - Comprehensive analysis of Helicobacter pylori infection-associated diseases based on miRNA-mRNA interaction network. AB - Helicobacter pylori (H. pylori) infection remains a cause of significant morbidity and mortality worldwide. Comprehensive understanding of the pathogenic mechanism of H. pylori and its interaction with host will contribute to developing novel prophylactical and therapeutical strategies. Here, we first determined microRNA (miRNA) levels in H. pylori-infected patients with gastritis, duodenal ulcer, gastric cancer or mucosa-associated lymphoid tissue lymphoma using miRNA data sets. Thirty-four differentially expressed miRNAs were identified and functional enrichment analysis of those miRNA target genes revealed that H. pylori infection were strongly associated with pathway in cancer and regulation of mRNA synthesis. Using disease connectivity analysis of 28 hub genes, we found that H. pylori may increase the risk of many extragastric diseases (e.g. cardiovascular disease, hemic and lymphatic diseases and nervous system disease). Altogether, our integrated analysis provided a new method to predict pathogen-human disease connectivity based on miRNA-mRNA interaction network and indicated anti-H. pylori therapy as an effective means of human diseases prevention. PMID- 29579226 TI - CEP peptide hormones: key players in orchestrating nitrogen-demand signalling, root nodulation, and lateral root development. AB - Secreted peptide hormones play pivotal roles in plant growth and development. So far, CEPs (C-TERMINALLY ENCODED PEPTIDEs) have been shown to act through CEP receptors (CEPRs) to control nitrogen (N)-demand signalling, nodulation, and lateral root development. Secreted CEP peptides can enter the xylem stream to act as long-distance signals, but evidence also exists for CEPs acting in local circuits. Recently, CEP peptide species varying in sequence, length, and post translational modifications have been identified. A more comprehensive understanding of CEP biology requires insight into the in planta function of CEP genes, CEP peptide biogenesis, the components of CEP signalling cascades and, finally, how CEP peptide length, amino-acid composition, and post-translational modifications affect biological activity. In this review, we highlight recent studies that have advanced our understanding in these key areas and discuss some future directions. PMID- 29579225 TI - Distinct telomere length and molecular signatures in seminoma and non-seminoma of testicular germ cell tumor. AB - Testicular germ cell tumors (TGCTs) are classified into two main subtypes, seminoma (SE) and non-seminoma (NSE), but their molecular distinctions remain largely unexplored. Here, we used expression data for mRNAs and microRNAs (miRNAs) from The Cancer Genome Atlas (TCGA) to perform a systematic investigation to explain the different telomere length (TL) features between NSE (n = 48) and SE (n = 55). We found that TL elongation was dominant in NSE, whereas TL shortening prevailed in SE. We further showed that both mRNA and miRNA expression profiles could clearly distinguish these two subtypes. Notably, four telomere-related genes (TelGenes) showed significantly higher expression and positively correlated with telomere elongation in NSE than SE: three telomerase activity-related genes (TERT, WRAP53 and MYC) and an independent telomerase activity gene (ZSCAN4). We also found that the expression of genes encoding Yamanaka factors was positively correlated with telomere lengthening in NSE. Among them, SOX2 and MYC were highly expressed in NSE versus SE, while POU5F1 and KLF4 had the opposite patterns. These results suggested that enhanced expression of both TelGenes (TERT, WRAP53, MYC and ZSCAN4) and Yamanaka factors might induce telomere elongation in NSE. Conversely, the relative lack of telomerase activation and low expression of independent telomerase activity pathway during cell division may be contributed to telomere shortening in SE. Taken together, our results revealed the potential molecular profiles and regulatory roles involving the TL difference between NSE and SE, and provided a better molecular understanding of this complex disease. PMID- 29579227 TI - Endovascular repair of a subclavian artery aneurysm in Behcet's disease. AB - Behcet's disease is a rare, chronic, relapsing condition comprising multisystemic inflammatory dysfunction, whereas subclavian artery aneurysm is a rare peripheral atherosclerotic aneurysm that has a high risk of rupture or embolization. Herein, we report the case of a 32-year-old man with Behcet's disease who developed pseudoaneurysm of the left subclavian artery. He was admitted to the emergency department due to radiating pain in the left neck and shoulder. Endovascular repair was performed, and high-dose anti-inflammatory therapy was begun. Ultrasonography performed on postoperative day 3 showed good stent patency. Endovascular therapy may be a safe and effective treatment for arterial aneurysm in patients with Behcet's disease.

AB - Objective: To perform a thorough assessment of the recently published Mint Trials in order to illustrate how to read and analyze a study critically, according to principles of evidence-based medicine. Design: Narrative review. Method: We have applied the recently published guidelines for composing and assessing studies on the treatment of pain to a recently published article describing a large study that claimed its "findings do not support the use of radiofrequency denervation to treat chronic low back pain." These guidelines describe the critical components of a high-quality manuscript that allows communication of all relevant information from authors to readers. Results: Application of evidence-based medicine principles to the publication describing the Mint Trials reveals significant issues with the methodology and conclusions drawn by the authors. A thorough assessment demonstrates issues with inclusion/exclusion criteria, diagnostic block protocols, radiofrequency neurotomy technique, co-interventions, outcome measurement, power analysis, study sample characteristics, data analysis, and loss to follow-up. A failure to definitively establish a diagnosis, combined with use of an inadequate technique for radiofrequency neurotomy and numerous other methodological flaws, leaves the reader unable to draw meaningful conclusions from the study data. Conclusions: Critical analysis, rooted in principles of evidence-based medicine, must be employed by writers and readers alike in order to encourage transparency and ensure that appropriate conclusions are drawn from study data. PMID- 29579233 TI - Systematic Review and Meta-Analysis to Assess the Safety of Buproprion and Varenicline in Pregnancy. AB - Introduction: Smoking in pregnancy is a substantial public health issue, but, apart from nicotine replacement therapy (NRT), pharmacological therapies are not generally used to promote cessation. Bupropion and varenicline are effective cessation methods in non-pregnant smokers and this systematic review investigates their safety in pregnancy. Methods: We searched MEDLINE, EMBASE, CINAHL and PsychINFO databases for studies of any design reporting pregnancy outcomes after bupropion or varenicline exposure. We included studies of bupropion used for smoking cessation, depression, or where the indication was unspecified. Depending on study design, quality was assessed using the Newcastle-Ottawa Scale or Cochrane Risk of Bias Tool. Most findings are reported narratively but meta analyses were used to produce pooled estimates for the proportion of live births with congenital malformations and of the mean birthweight and gestational age at delivery following bupropion exposure. Results: 18 studies were included: two randomised controlled trials, eleven cohorts, two case-control studies and three case reports. Study quality was variable. Gestational safety outcomes were reported in 14 bupropion and four varenicline studies. Meaningful meta-analysis was only possible for bupropion exposure, for which the pooled estimated proportion of congenital malformations amongst live-born infants was 1.0% (95% CI= 0.0-3.0%, I2= 80.9%, 4 studies) and the mean birthweight and mean gestational age at delivery was 3305.9g (95% CI= 3173.2-3438.7g, I2= 77.6%, 5 studies) and 39.2 weeks (95% CI= 38.8-39.6, I2= 69.9%, 5 studies) respectively. Conclusions: There was no strong evidence that either major positive or negative outcomes were associated with gestational use of bupropion or varenicline. PROSPERO registration number CRD42017067064. Implications: We believe this to be the first systematic review investigating the safety of bupropion and varenicline in pregnancy. Meta-analysis of outcomes following bupropion exposure in pregnancy suggests that there are no major positive or negative impacts on the rate of congenital abnormalities, birthweight or premature birth. Overall, we found no evidence that either of these treatments might be harmful in pregnancy, and no strong evidence to suggest safety, but available evidence is of poor quality. PMID- 29579235 TI - Duodenoscope-Related Outbreak of a Carbapenem-Resistant Klebsiella pneumoniae Identified Using Advanced Molecular Diagnostics. AB - Background: Carbapenem-resistant Klebsiella pneumoniae infections are increasingly prevalent in North American hospitals. We describe an outbreak of carbapenem-resistant K. pneumoniae containing the blaOXA-232 gene transmitted by contaminated duodenoscopes during endoscopic retrograde cholangiopancreatography (ERCP) procedures. Methods: An outbreak investigation was performed when 9 patients with blaOXA-232 carbapenem-resistant K. pneumoniae infections were identified at a tertiary care hospital. The investigation included 2 case-control studies, review of duodenoscope reprocessing procedures, and culture of devices. Carbapenem-resistant Enterobacteriacieae (CRE) isolates were evaluated with polymerase chain reaction analysis for carbapenemase genes, and isolates with the blaOXA-232 gene were subjected to whole-genome sequencing and chromosome single nucleotide polymorphism analysis. On recognition of ERCP as a key risk factor for infection, targeted patient notification and CRE screening cultures were performed. Results: Molecular testing ultimately identified 17 patients with blaOxa-232 carbapenem-resistant K. pneumoniae isolates, including 9 with infections, 7 asymptomatic carriers who had undergone ERCP, and 1 additional patient who had been hospitalized in India and was probably the initial carrier. Two case-control studies established a point-source outbreak associated with 2 specific duodenoscopes. A field investigation of the use, reprocessing, and storage of deuodenoscopes did not identify deviations from US Food and Drug Administration or manufacturer recommendations for reprocessing. Conclusions: This outbreak demonstrated the previously underappreciated potential for duodenoscopes to transmit disease, even after undergoing high-level disinfection according to manufacturers' guidelines. PMID- 29579234 TI - Community-led comparative genomic and phenotypic analysis of the aquaculture pathogen Pseudomonas baetica a390T sequenced by Ion semiconductor and Nanopore technologies. AB - Pseudomonas baetica strain a390T is the type strain of this recently described species and here we present its high-contiguity draft genome. To celebrate the 16th International Conference on Pseudomonas, the genome of P. baetica strain a390T was sequenced using a unique combination of Ion Torrent semiconductor and Oxford Nanopore methods as part of a collaborative community-led project. The use of high-quality Ion Torrent sequences with long Nanopore reads gave rapid, high contiguity and -quality, 16-contig genome sequence. Whole genome phylogenetic analysis places P. baetica within the P. koreensis clade of the P. fluorescens group. Comparison of the main genomic features of P. baetica with a variety of other Pseudomonas spp. suggests that it is a highly adaptable organism, typical of the genus. This strain was originally isolated from the liver of a diseased wedge sole fish, and genotypic and phenotypic analyses show that it is tolerant to osmotic stress and to oxytetracycline. PMID- 29579236 TI - Improvements in Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) Trapping Systems. AB - Improved trap efficacy is crucial for implementing control methods for red palm weevil, Rhynchophorus ferrugineus (Olivier; Coleoptera: Dryophthoridae), based on trapping systems, such as mass trapping, attract and infect or attract and sterilize techniques. Although new trap designs have been proposed and aggregation pheromone dispensers have been optimized, aspects such as the use of co-attractants (molasses) and trap placement are still not well defined and standardized. The efficacy of three concentrations of molasses and different formulations to reduce water evaporation in traps was studied in different field trials to improve trapping systems and to prolong trap servicing periods. In addition, the performance of installing groups of traps or single traps was also evaluated with the aim of improving the attracted/captured weevils ratio. Our results showed that captures increased when molasses were added at 15% to the water contained in the trap and that a thin layer of oil, created by adding 2-3% of paraffinic oil to water, was able to effectively reduce evaporation and prolong trap servicing periods. Moreover, 3.5-fold more weevils were captured when placing five traps instead of one at the same trapping point. Results obtained allow improved efficacy and may have an impact in the economic viability of trapping systems and, therefore, in integrated pest management programs. PMID- 29579238 TI - Pulmonary Colonization Resistance to Pathogens via Noncanonical Wnt and Interleukin-17A by Intranasal pep27 Mutant Immunization. AB - Background: Previous studies have focused on colonization resistance of the gut microbiota against antibiotic resistant strains. However, less research has been performed on respiratory colonization resistance. Methods: Because respiratory colonization is the first step of respiratory infections, intervention to prevent colonization would represent a new approach for preventive and therapeutic measures. The Th17 response plays an important role in clearance of respiratory pathogens. Thus, harnessing the Th17 immune response in the mucosal site would be an effective method to design a respiratory mucosal vaccine. Results: In this study, we show that intranasal Deltapep27 immunization induces noncanonical Wnt and subsequent interleukin (IL)-17 secretion, and it inhibits Streptococcus pneumoniae, Staphylococcus aureus, and Klebsiella pneumoniae colonization. Moreover, IL-17A neutralization or nuclear factor of activated T-cell inhibition augmented bacterial colonization, indicating that noncanonical Wnt signaling is involved in pulmonary colonization resistance. Conclusions: Therefore, Deltapep27 immunization can provide nonspecific respiratory colonization resistance via noncanonical Wnt signaling and IL-17A-related pathways. PMID- 29579237 TI - Acid ceramidase inhibition ameliorates alpha-synuclein accumulation upon loss of GBA1 function. AB - GBA1 encodes the lysosomal enzyme beta-glucocerebrosidase (GCase) which converts glucosylceramide into ceramide and glucose. Mutations in GBA1 lead to Gaucher's disease and are a major risk factor for Parkinson's disease (PD) and Dementia with Lewy bodies (DLB), synucleinopathies characterized by accumulation of intracellular alpha-synuclein. In this study, we examined whether decreased ceramide that is observed in GCase-deficient cells contributes to alpha-synuclein accumulation. We demonstrated that deficiency of GCase leads to a reduction of C18-ceramide species and altered intracellular localization of Rab8a, a small GTPase implicated in secretory autophagy, that contributed to impaired secretion of alpha-synuclein and accumulation of intracellular alpha-synuclein. This secretory defect was rescued by exogenous C18-ceramide or chemical inhibition of lysosomal enzyme acid ceramidase that converts lysosomal ceramide into sphingosine. Inhibition of acid ceramidase by carmofur resulted in increased ceramide levels and decreased glucosylsphingosine levels in GCase-deficient cells, and also reduced oxidized alpha-synuclein and levels of ubiquitinated proteins in GBA1-PD patient-derived dopaminergic neurons. Together, these results suggest that decreased ceramide generation via the catabolic lysosomal salvage pathway in GCase mutant cells contributes to alpha-synuclein accumulation, potentially due to impaired secretory autophagy. We thus propose that acid ceramidase inhibition which restores ceramide levels may be a potential therapeutic strategy to target synucleinopathies linked to GBA1 mutations including PD and DLB.

Twenty-two barrows (initial BW: 14.09 +/- 1.48 kg) were surgically fitted with a T-cannula in the distal ileum and randomly allotted to a replicated 11 * 4 incomplete Latin square design with 11 diets and four 7-d periods in each square. Eleven experimental diets were prepared and test ingredients were the sole source of CP and AA in 10 diets and the eleventh diet was a N-free diet used to measure basal ileal endogenous losses of CP and AA. Chromic oxide (0.4%) was included in all diets as an indigestible marker and ileal digesta were collected on day 6 and 7 of each period. Results indicated that the SID of CP and AA was greatest (P < 0.05) in brewers rice and sesame meal and least (P < 0.05) in cassava meal. The SID of indispensable AA was greater (P < 0.05) in sesame meal compared with all other ingredients except brewers rice. Full-fat rice bran had greater (P < 0.05) SID of Arg, Ile, Leu, Lys, and Met compared with DFRB. The SID of CP and most AA was not different among rapeseed meal, rapeseed expellers, and soybean expellers. Bakery meal had the least (P < 0.05) SID of most AA compared with all other ingredients, with the exception of cassava meal. The concentration of standardized ileal digestible CP was greater (P < 0.05) in sesame meal and peanut meal (482.32 and 452.44 g/kg DM, respectively) than in all other ingredients. Soybean expellers had the greatest (P < 0.05) concentration of standardized ileal digestible Lys (22.98 g/kg DM) followed by rapeseed meal (16.11 g/kg DM) and rapeseed expellers (16.17 g/kg DM). Cassava meal and bakery meal had the least (P < 0.05) concentration of standardized ileal digestible CP and most AA compared with the other ingredients. Concentrations of standardized ileal digestible CP and AA in brewers rice, FFRB, and DFRB were less (P < 0.05) than in rapeseed meal, rapeseed expellers, and soybean expellers. In conclusion, peanut meal and sesame meal have greater concentrations of standardized ileal digestible CP and most AA, with the exception of Lys, than other ingredients. Rapeseed meal, rapeseed expellers, and soybean expellers have the greatest concentrations of standardized ileal digestible Lys. PMID- 29579240 TI - Lethal and Sublethal Effects of Various Pesticides on Trichogramma achaeae (Hymenoptera: Trichogrammatidae). AB - Little information is available regarding the lethal and sublethal effects of pesticides on Trichogramma achaeae (Nagaraja and Nagarkatti; Hymenoptera: Tricogrammatidae) during integrated management of Tuta absoluta (Meyrick; Lepidoptera: Gelechiidae), an important pest for tomato production. Twenty-two pesticides sprayed on Ephestia kuehniella (Zeller; Lepidoptera: Pyralidae) eggs were evaluated on the mortality of adult parasitoids upon contact with the hosts 24 h after the treatments and their sublethal effects on the parasitoids were assessed in laboratory conditions. Tests were carried out with fresh solutions at the recommended concentration. According to the International Organisation for Biological and Integrated Control (IOBC) standards, chlorpyrifos is harmful to the parasitoid; merthiocarb, methomyl, spinosad lambda-cyhalothrin, and acrinatrin are moderately harmful; and chlorantraniliprole, lufenuron, hexythiazox, cyromazine and Bacillus thuringiensis have no effect on the parasitoid. Sulfur is slightly harmful, and azoxystrobin is harmless. Chlorpyrifos was the most lethal among these pesticides and killed all females in less than 24 h. All other pesticides affected the biological parameters of T. achaeae to varying degrees. Regarding the lethal and sublethal effects, merthiocarb and spinosad killed all female offspring in less than 24 h; lambda cyhalothrin and sulfur reduced the number of parasitized eggs; and acrinatrin, deltamethrin and azoxystrobin affected the emergence rate. After that, we can recommend the use of chlorantraniliprole and B. thuringiensis to control Lepidoptera, cyromazine to control Diptera, pirimicarb to control Homoptera, hexythiazox to control mites and azoxystrobin can be used as fungicide in an integrated pest management program with mass released of T. achaeae. PMID- 29579241 TI - Systematic review: What works to address obesity in nurses? AB - Background: There is evidence that the prevalence of overweight and obesity among nurses is increasing. As well as the impact on health, the costs associated with obesity include workplace injury, lost productivity and sickness absence. Finding ways to address obesity in nurses may be a challenge because of the barriers they face in leading a healthy lifestyle. Aims: To identify the available evidence for interventions to address obesity in nurses. Methods: Databases searched included CINAHL, SCOPUS (which encompasses the Cochrane Database of Systematic Reviews), PsycINFO, MEDLINE and British Nursing Index. Ancillary searching of the grey literature was conducted for case studies of weight management interventions in National Health Service (NHS) settings. Inclusion criteria were studies involving nurses that reported on interventions addressing health behaviours that contribute to obesity and included at least one obesity-related outcome measure. Results: Eleven primary studies were found concerning lifestyle interventions for nurses. There was no strong evidence for any particular intervention to address obesity, although integrating interventions into nurses' daily working lives may be important. Case studies from the grey literature showcased a range of interventions, but very few studies reported outcomes. Conclusions: The review demonstrates that there is insufficient good-quality evidence about successful interventions to address obesity in nurses. Evidence does indicate that interventions should be designed around the specific barriers nurses may face in leading a healthy lifestyle. PMID- 29579242 TI - Primary hepatic pregnancy. PMID- 29579243 TI - Aortic cross-clamp time and cardiopulmonary bypass time: prognostic implications in patients operated on for infective endocarditis. AB - OBJECTIVES: Prolonged aortic cross-clamp (XCT) and cardiopulmonary bypass time (CPBT) are associated with increased morbidity and mortality following cardiac surgery. The aim of this study was to assess the predictors of mortality and other severe postoperative complications in patients undergoing surgery for infective endocarditis (IE), focusing in particular on the role of prolonged XCT and CPBT. METHODS: A retrospective single-centre study was conducted from January 2000 to January 2017, including all patients undergoing valvular surgery for IE. The primary end point was early postoperative mortality. The main secondary end point was a composite end point for severe postoperative complications. RESULTS: During the study period, 264 patients were included. Early postoperative mortality was 14%. Prolonged CPBT [odds ratio (OR) 1.008, 95% confidence intervals (CIs) 1.003-1.01; P = 0.009] and increasing age (OR 1.04, 95% CI 1.01 1.07; P = 0.02) independently predicted mortality, while an inverse association was observed for left ventricular ejection fraction (OR 0.93, 95% CI 0.89-0.97; P = 0.0007). The best mortality cut-offs were >72 min for XCT and >166 min for CPBT. Prolonged CPBT also predicted severe complications, along with age, stroke, preoperative mechanical ventilation and reduced left ventricular ejection fraction. When XCT was included in the multivariable models instead of CPBT, it was associated with both mortality and severe complications. CONCLUSIONS: Prolonged XCT and CPBT are associated with mortality and development of severe complications after valvular surgery for IE. Further validation of safe limits for XCT and CPBT might provide novel insights on how to improve intraoperative and postoperative outcomes of patients with IE. PMID- 29579244 TI - DNA Damage Response of 4-Chloro-Ortho-Toluidine in Various Rat Tissues. AB - The potential of 4-chloro-ortho-toluidine (4-CloT), an aromatic amine substituted on the ortho- and para-position of the amine function, to induce DNA damage in male Wistar rats was evaluated with the micronucleus test (peripheral blood), Pig a (peripheral blood), and comet assay (peripheral blood, liver, urinary bladder, jejunum) at several time points. In addition to those markers of DNA damage, ie, gene mutation and clastogenicity, standard hematology, including methemoglobin, histopathology and immunohistochemistry of gamma-H2AX and Ki-67 in liver, jejunum, and urinary bladder were performed. 4-CloT was administered orally over 28 consecutive days (days 1-28), followed by a 28-day treatment-free (days 29 56), and a second dosing phase of 3 days (days 57-59). 4-CloT showed some effects on the integrity of the DNA as measured by the comet assay in liver and urinary bladder but not in peripheral blood or jejunum. However, for liver and urinary bladder histopathological changes were observed. An increase in the frequency of micronuclei in peripheral blood was seen in parallel to a dose-dependent increase of reticulocytes and methemoglobin. Therefore, impact from a compensatory erythropoiesis on micronucleation cannot be excluded. Interestingly, no increase in the frequency of RETCD59- and RBCCD59- was observed in the Pig-a assay. PMID- 29579245 TI - The bHLH transcription factor GmPIB1 facilitates resistance to Phytophthora sojae in Glycine max. AB - Phytophthora sojae Kaufmann and Gerdemann causes Phytophthora root rot, a destructive soybean disease worldwide. A basic helix-loop-helix (bHLH) transcription factor is thought to be involved in the response to P. sojae infection in soybean, as revealed by RNA sequencing (RNA-seq). However, the molecular mechanism underlying this response is currently unclear. Here, we explored the function and underlying mechanisms of a bHLH transcription factor in soybean, designated GmPIB1 (P. sojae-inducible bHLH transcription factor), during host responses to P. sojae. GmPIB1 was significantly induced by P. sojae in the resistant soybean cultivar 'L77-1863'. Analysis of transgenic soybean hairy roots with elevated or reduced expression of GmPIB1 demonstrated that GmPIB1 enhances resistance to P. sojae and reduces reactive oxygen species (ROS) accumulation. Quantitative reverse transcription PCR and chromatin immunoprecipitation quantitative PCR assays revealed that GmPIB1 binds directly to the promoter of GmSPOD1 and represses its expression; this gene encodes a key enzyme in ROS production. Moreover, transgenic soybean hairy roots with GmSPOD1 silencing through RNA interference exhibited improved resistance to P. sojae and reduced ROS generation. These findings suggest that GmPIB1 enhances resistance to P. sojae by repressing the expression of GmSPOD1. PMID- 29579246 TI - High-sensitivity cardiac troponin and natriuretic peptide with risk of lower extremity peripheral artery disease: the Atherosclerosis Risk in Communities (ARIC) Study. AB - Aims: Cardiac troponin T (cTnT) is suggested as a predictor of amputation in patients with peripheral artery disease (PAD). However, cTnT-PAD association has not been systematically studied in a large study. This study evaluated the association of high-sensitivity cTnT (hs-cTnT) with PAD incidence and also explored whether natriuretic peptide (NT-proBNP), another representative cardiac marker, predicts PAD risk. Methods and results: Among 12 288 middle-aged adults, the associations of hs-cTnT and NT-proBNP with incident PAD (hospitalizations with PAD diagnosis or leg revascularization [cases with rest pain or tissue loss considered as critical limb ischaemia (CLI)]) were quantified with multivariable Cox regression models. The risk discrimination was assessed by c-statistic. During a follow-up over 22 years, 454 participants developed PAD (164 CLI cases). In demographically adjusted models, the highest category of hs-cTnT (>=14 vs. <3 ng/L) and NT-proBNP (>=258.3 vs. <51.5 pg/mL) showed ~8- and 10-20-fold higher risk of PAD and CLI, respectively. Even after adjusting for potential confounders and each other, hazard ratios were greater for CLI than for PAD (7.74 95% confidence interval [95% CI 4.43-13.55] vs. 2.84 [2.02-4.00] for the highest vs. reference hs-cTnT category and 4.63 [2.61-8.23] vs. 3.16 [2.23-4.49] for the highest vs. reference NT-proBNP category). The addition of these cardiac markers improved c-statistics for CLI. Conclusion: High-sensitivity cTnT and NT-proBNP were independently associated with incident PAD, particularly its severe form, CLI. Although future studies are warranted to investigate pathophysiological mechanisms behind these associations, our study suggests the usefulness of cardiac markers to identify individuals at high risk of CLI. PMID- 29579247 TI - Reduced fecundity in HIV-positive women. AB - STUDY QUESTION: Is HIV associated with increased time to pregnancy (TTP)? SUMMARY ANSWER: HIV-positive women who discontinue a contraceptive method to become pregnant have increased TTP, particularly among those who likely do not know their status. WHAT IS KNOWN ALREADY: HIV-positive women have fewer children on average than their HIV-negative counterparts due to both behavioral and biological factors. There is a need to better describe and quantify fecundity patterns associated with HIV in the general population. STUDY DESIGN, SIZE, DURATION: This cross-sectional study was based on data from 12 Demographic and Health Surveys (DHSs) conducted between 2003 and 2013 in 11 African countries. All studies collected dried blood spot samples for HIV testing and included a retrospective calendar module that recorded women's monthly reproductive status in the 5 years preceding the survey. TTP was measured among 3181 women discontinuing a contraceptive method within 2 years of the survey in order to become pregnant. PARTICIPANTS/MATERIALS, SETTING, METHODS: We use Cox proportional hazard models for discrete survival data to model TTP and estimate fecundability odds ratios (FOR) and 95% CIs for the 12-month period following contraceptive discontinuation. In addition to employing a binary measure of HIV status, we also develop an additional explanatory measure that combines HIV status with information on whether respondents had ever been tested for HIV and received their results (which proxies for knowledge of HIV status) to reduce the threat of confounding from behavioral changes following an HIV diagnosis. MAIN RESULTS AND THE ROLE OF CHANCE: In our sample, 10.3% of women were HIV-positive, and a little more than half (51.8%) of women received test results and likely knew their status. Over a 12-month observation period, HIV-positive women had a 25% average reduction in fecundity compared to HIV-negative women [adjusted FOR (aFOR) = 0.75 (0.62-0.92)] after adjusting for confounders. The 12-month fecundity patterns differed by women's likely knowledge of their status such that results were primarily driven by HIV-positive women who likely did not know their status. Moreover, reductions in fecundity attributable to HIV were not uniform over time. Among women who were still trying for pregnancy after 3 unsuccessful months, HIV-positive women had half the odds of becoming pregnant compared to HIV negative women [aFOR = 0.50 (0.35-0.71)]. Conversely, there were no significant differences in FORs between HIV-negative and HIV-positive women in the first 3 months. LIMITATIONS REASONS FOR CAUTION: Because dried blood spot samples for HIV testing were collected at the time of the survey but reproductive calendar data were collected retrospectively, it is possible that we introduced misclassification bias, as we have no knowledge if the acquisition of HIV occurred before or after pregnancy attempt. WIDER IMPLICATIONS OF THE FINDINGS: As life expectancy and quality health status improve due to earlier initiation of antiretroviral (ARV) treatment in HIV-positive women, there has been growing awareness that services should also address the fertility desires of HIV-positive women who want children. These findings indicate that if a pregnancy does not occur after 3 months of attempting pregnancy, HIV-positive women and HIV discordant couples should request access to HIV and reproductive pre-pregnancy counseling and health assessments.

PMID- 29579248 TI - Leber's hereditary optic neuropathy (LHON)-associated ND5 12338T > C mutation altered the assembly and function of complex I, apoptosis and mitophagy. AB - Mutations in mitochondrial DNA (mtDNA) have been associated with Leber's hereditary optic neuropathy (LHON) and their pathophysiology remains poorly understood. In this study, we demonstrated that a missense mutation (m.12338T>C, p.1M>T) in the ND5 gene contributed to the pathogenesis of LHON. The m.12338T>C mutation affected the first methionine (Met1) with a threonine and shortened two amino acids of ND5. We therefore hypothesized that the mutated ND5 perturbed the structure and function of complex I. Using the cybrid cell models, generated by fusing mtDNA-less (rho degrees ) cells with enucleated cells from LHON patients carrying the m.12338T>C mutation and a control subject belonging to the same mtDNA haplogroup, we demonstrated that the m.12338T>C mutation caused the reduction of ND5 polypeptide, perturbed assemble and activity of complex I. Furthermore, the m.12338T>C mutation caused respiratory deficiency, diminished mitochondrial adenosine triphosphate levels and membrane potential and increased the production of reactive oxygen species. The m.12338T>C mutation promoted apoptosis, evidenced by elevated release of cytochrome c into cytosol and increased levels of apoptosis-activated proteins: caspases 9, 3, 7 and Poly ADP ribose polymerase in the cybrids carrying the m.12338T>C mutation, as compared with control cybrids. Moreover, we also document the involvement of m.12338T>C mutation in decreased mitophagy, as showed by reduced levels of autophagy protein light chain 3 and accumulation of autophagic substrate p62 in the in mutant cybrids as compared with control cybrids. These data demonstrated the direct link between mitochondrial dysfunction caused by complex I mutation and apoptosis or mitophagy. Our findings may provide new insights into the pathophysiology of LHON. PMID- 29579249 TI - A misleading diagnosis of granulomatosis with polyangiitis disguising Whipple's disease. PMID- 29579250 TI - Reduction in Cigarettes Per Day Prospectively Predicts Making a Quit Attempt: A Fine-Grained Secondary Analysis of a Natural History Study. AB - Introduction: Reducing cigarettes per day (CPD) aided by medication increases quit attempts (QA) among smokers not trying to quit. If this is due to reducing CPD per se, then a greater reduction should predict making a QA. Methods: In this secondary analysis, 132 smokers completed nightly calls to report CPD, intention to quit tomorrow, and QAs over 12 weeks. We provided no treatment. We identified episodes of reduction and tested whether a) percent reduction in CPD, b) absolute CPD reduced, c) duration of reduction, or d) CPD on the final day, predicted a QA immediately after a reduction episode. We tested this separately among reduction episodes that began with and without an intention to quit. Results: Among the 1,179 episodes that began without intention to quit, all four measures of reduction predicted making a QA. Greater percent reduction, longer duration, and fewer CPD on the final day were retained in a multivariate model (all p<.05). Among the 85 episodes that began with intention to quit, greater percent reduction and greater absolute reduction predicted making a QA. Only mean percent reduction was retained in a multivariate model (p<.001). Conclusions: Our results replicate and extend earlier studies by using fine-grain analyses and examining immediately proximal QAs in a sample of self-quitters. Findings suggest that reducing CPD per se increases the probability of a QA among smokers without intention to quit in a dose-related manner. Whether this is the case among smokers who intend to quit remains unclear. Implications: Reducing CPD appears to be an effective strategy to increase the probability of making a QA for the majority of smokers who do not intend to quit in the near future. However, our findings are mixed regarding the effectiveness of reducing among smokers who intend to quit. Clinical interventions and polices that promote reducing CPD are likely to be an effective way to increase QAs. Reduction may be especially helpful for smokers who have not responded to traditional advice to stop abruptly. PMID- 29579251 TI - Incidence of Healthcare-Associated Influenza-Like Illness After a Primary Care Encounter Among Young Children. AB - Background: Despite potential respiratory virus transmission in pediatric clinics, little is known about the risk of healthcare-associated viral infections attributable to outpatient encounters. We evaluated whether exposure to a pediatric clinic visit was associated with subsequent influenza-like illness (ILI). Methods: Using electronic health record data, we conducted a retrospective cohort study of all children aged <6 years who presented to a provider in a 29 clinic pediatric primary care network for a non-ILI-related encounter over 2 respiratory virus seasons (September 1, 2012, to April 30, 2014). We defined a risk period for potential healthcare-associated (HA) ILI of 1 to 8 days after a non-ILI clinic visit and identified all cases of ILI to compare the incidences of ILI visits 1 to 8 days after a non-ILI encounter and those of visits >8 days after a non-ILI encounter. Results: Among 149987 children <6 years of age (mean age, 2.5 years) with >=1 non-ILI visit during the study period, 531928 total encounters and 13951 (2.9%) ILI encounters were identified; 1941 (13.9%) occurred within the HA-ILI risk window. The incidence rate ratios (IRRs) for ILI 1 to 8 days after compared with ILI >8 days after a non-ILI visit during season 1 were 1.36 (95% confidence interval, 1.22-1.52) among children >=2 years of age and 1.01 (95% confidence interval, 0.93-1.09) among children <2 years of age. Estimates remained consistent during season 2 and with a risk window of 3, 4, or 9 days. Conclusions: Pediatric clinic visits during a respiratory virus season were significantly associated with an increased incidence of subsequent ILI among children aged 2 to 6 years but not among those aged <2 years. These findings support the hypothesis that respiratory virus transmission in a pediatric clinic can result in HA ILI in young children. PMID- 29579252 TI - Epigenetic modulation as a therapy in systemic sclerosis. AB - SSc is an autoimmune idiopathic disease in which there is an inflammatory component driving fibrosis. The chief cell involved is the myofibroblast, which when activated secretes copious amounts of extracellular matrix that forms deposits, leading to stiffness and fibrosis. The fibrosis is most prevalent in the skin and lungs. In recent years epigenetic modifications have been uncovered that positively and negatively regulate the genesis of the myofibroblasts and that can be activated and regulated by a variety of cytokines and hormones. The epigenetic contribution to these cells and to SSc is only now really coming to light, and this opens up a new therapeutic target for the disease for which many epigenetic drugs, such as miRNA replacements, are beginning to be developed. This review will examine the epigenetic regulators in the disease and possible targeting of these. PMID- 29579254 TI - The Tendril Plot-a novel visual summary of the incidence, significance and temporal aspects of adverse events in clinical trials. AB - Background: In contrast to efficacy, safety hypotheses of clinical trials are not always pre-specified, and therefore, the safety interpretation work of a trial tends to be more exploratory, often reactive, and the analysis more statistically and graphically challenging. Methods: We introduce a new means of visualizing the adverse event data across an entire clinical trial. Results: The approach overcomes some of the current limitations of adverse event analysis and streamlines the way safety data can be explored, interpreted and analyzed. Using a phase II study, we describe and exemplify how the tendril plot effectively summarizes the time-resolved safety profile of two treatment arms in a single plot and how that can provide scientists with a trial safety overview that can support medical decision making. Conclusion: To our knowledge, the tendril plot is the only way to graphically show important treatment differences with preserved temporal information, across an entire clinical trial, in a single view. PMID- 29579253 TI - Diverse Evolutionary Origins and Mechanisms of Lens Regeneration. AB - In this review, we compare and contrast the three different forms of vertebrate lens regeneration: Wolffian lens regeneration, cornea-lens regeneration, and lens regeneration from lens epithelial cells. An examination of the diverse cellular origins of these lenses, their unique phylogenetic distribution, and the underlying molecular mechanisms, suggests that these different forms of lens regeneration evolved independently and utilize neither conserved nor convergent mechanisms to regulate these processes. PMID- 29579255 TI - Performance of In Silico Models for Mutagenicity Prediction of Food Contact Materials. AB - In silico methodologies, such as (quantitative) structure-activity relationships ([Q]SARs), are available to predict a wide variety of toxicological properties and biological activities for structurally diverse substances. To obtain insights in the scientific value of these predictions, the capacity of the prediction models to generate (sufficiently) reliable results for a particular type of compounds needs to be evaluated. In the current study, performance parameters to predict the endpoint "bacterial mutagenicity" were calculated for a battery of common (Q)SAR tools, namely Toxtree, Derek Nexus, VEGA Consensus, and Sarah Nexus. Printed paper and board food contact material (FCM) constituents were chosen as study substances because many of these lack experimental data, making them an interesting group for in silico screening. Accuracy, sensitivity, specificity, positive predictivity, negative predictivity, and Matthews correlation coefficient for the individual models and for the combination of VEGA Consensus and Sarah Nexus were determined and compared. Our results demonstrate that performance varies among the four models, but can be increased by applying a combination strategy. Furthermore, the importance of the applicability domain is illustrated. Limited performance to predict the mutagenic potential of substances that are new to the model (ie, not included in the training set) is reported. In this context, the generally poor sensitivity for these new substances is also addressed. PMID- 29579256 TI - Characterization of the Neutralizing Antibody Response in a Case of Genetically Linked HIV Superinfection. AB - This report describes the identification of a genetically confirmed linked heterosexual human immunodeficiency virus (HIV) superinfection (HIV-SI) in a woman with chronic HIV infection who acquired a second strain of the virus from her husband. Serum neutralizing antibody (NAb) responses against their homologous and heterologous viruses, including the superinfecting strain, in the woman and her husband were examined before and after onset of HIV-SI. The woman displayed a moderately potent and broad anti-HIV NAb response prior to superinfection but did not possess NAb activity against the superinfecting strain. This case highlights the unique potential of linked HIV-SI studies to examine natural protection from HIV infection. PMID- 29579257 TI - Pyloroplasty may reduce weight loss 1 year after esophagectomy. AB - Weight loss after esophagectomy is common and is associated with unfavorable prognosis. However, the clinical features and surgical methods that influence postesophagectomy weight loss are not well characterized. This study aims to determine those features (especially the surgical methods) that may affect postoperative weight loss. We reviewed 221 esophageal cancer patients who had undergone esophagectomy at Kumamoto University Hospital (Kumamoto, Japan) between November 2012 and June 2015. Among these, we recruited 106 patients who had undergone transthoracic esophagectomy with gastric conduit reconstruction, had no cancer recurrence within 1 year, and no missing follow-up data. We tabulated the body weight changes and risk factors associated with weight loss exceeding 10% at 1-year postesophagectomy. The mean body weights at baseline and 1-year postsurgery were 60.3 kg (standard error (SE): 0.91) and 52.6 (SE: 0.91), respectively. One year postsurgery, the body weights had changed as follows: mean: -12.2%; median: -12.9%; standard deviation: 9.06; range: -36.1-18.56%; interquartile range: -10.5 to -14.0%. In the multivariate logistic regression analysis, the absence of pyloroplasty was the sole risk factor for more than 10% weight loss (OR: 3.22; 95% CI: 1.08-11.9; P = 0.036). Our data suggest that pyloroplasty with esophagectomy can overcome the post-surgical weight loss. PMID- 29579258 TI - DNA silencing by prokaryotic Argonaute proteins adds a new layer of defense against invading nucleic acids. AB - Argonaute (Ago) proteins are encoded in all three domains of life and are responsible for the regulation of intracellular nucleic acid levels. Whereas some Ago variants are able to cleave target nucleic acids by their endonucleolytic activity, others only bind to their target nucleic acids while target cleavage is mediated by other effector proteins. Although all Ago proteins show a high degree of overall structural homology, the nature of the nucleic acid binding partners differs significantly. Recent structural and functional data have provided intriguing new insights into the mechanisms of archaeal and bacterial Ago variants demonstrating the mechanistic diversity within the prokaryotic Ago family with astonishing differences in nucleic acid selection and nuclease specificity. In this review, we provide an overview of the structural organisation of archaeal Ago variants and discuss the current understanding of their biological functions that differ significantly from their eukaryotic counterparts. PMID- 29579260 TI - PAH exposure-associated lung cancer: an updated meta-analysis. AB - Background: Occupational exposure to polycyclic aromatic hydrocarbons (PAHs) has been shown to be associated with lung cancer in various epidemiological studies in industries such as aluminium reduction/smelting, coal gasification, coke production, iron/steel foundries, coal/coke and related products and carbon/graphite electrodes production. Aims: To update data on the association between PAH exposure and morbidity and mortality due to lung cancer among workers in different occupations, including smoking data. Methods: A comprehensive literature search was conducted to retrieve relevant papers for meta-analysis. Cohort studies with standardized mortality ratios or standardized incidence ratios and calculated overall risk ratio with their corresponding 95% confidence intervals (CIs) were included in the analysis. Chi-square test for heterogeneity was used to evaluate the consistency of findings between the studies. Results: A significant risk of lung cancer was observed among the coal/coke and related product industry 1.55 (95% CI 1.01-2.37) and the iron/steel foundry industry 1.52 (95% CI 1.05-2.20). There was a wide variation in smoking habits and PAHs exposure among studies. Conclusions: Coal/coke industry and iron/steel industry workers showed a higher risk of lung cancer compared with other occupations exposed to PAHs. The confounding effects of smoking and individual exposure levels of PAH should be taken into account. PMID- 29579261 TI - NeuroForm Atlas Stent-Assisted Coiling: Preliminary Results. AB - BACKGROUND: Stent-assisted coiling (SAC) is increasingly being performed as intervention for wide-neck intracranial aneurysms. The NeuroForm Atlas Stent (CE marked; Stryker, Kalamazoo, Michigan) is relatively new. OBJECTIVE: To evaluate the effectiveness and safety of NeuroForm Atlas SAC for intracranial aneurysms in the first such study. METHODS: We retrospectively analyzed data from all patients treated with the NeuroForm Atlas SAC of an intracranial aneurysm, both ruptured and unruptured, between June 2015 and December 2016. Primary end-points were favorable clinical outcomes (modified Rankin scale score 0-2) and successful aneurysm occlusion (Raymond-Roy class I/II), both at 6-mo follow-up. Secondary end-points were the occurrence of intervention-related complications leading to permanent neurological deficit, the occurrence of intervention-related stroke and neurological death, immediate aneurysm occlusion, rupture (or rerupture) of the aneurysm, and recanalization. RESULTS: Twenty-seven consecutive patients, 10 with ruptured saccular wide-neck aneurysms, were treated with NeuroForm Atlas SAC. At 6-mo follow-up, 18/26 (69.2%) survivors had successful aneurysm occlusion and 22/26 (84.6%) had favorable clinical outcome. One patient had died of a cause unrelated to treatment. No intervention-related complications leading to permanent neurological deficit occurred. However, intraprocedural thromboembolic complications occurred in 4/27 patients (14.8%), and ischemic stroke related to treatment occurred in 4/26 (15.4%). No hemorrhagic complications were observed. CONCLUSION: NeuroForm Atlas SAC is a feasible way to treat ruptured and unruptured wide-neck aneurysms that are not amenable to conventional coiling or clipping. Aneurysm occlusion and favorable clinical outcome are consistent with previously reported rates for SAC of wide-neck aneurysms with other devices. PMID- 29579262 TI - Acute kidney injury in critically ill patients with solid tumours. AB - Background: Patients with solid tumours are at risk for acute kidney injury (AKI), however, epidemiological data are limited. Methods: We conducted a study that included patients with solid tumours admitted to a single-centre intensive care unit (ICU) from January 2011 to December 2015. We analysed factors associated with the occurence of AKI, ICU and Day-90 mortality. Results: Two hundred and four patients were included. The incidence of AKI was 59%, chiefly related to sepsis (80%), hypovolaemia (40%) and outflow tract obstruction (17%). Renal replacement therapy was implemented in 12% of the patients, with a hospital mortality of 39%. Independent predictors of AKI were: Simplified Acute Physiological Score II (SAPS II) [odds ratio (OR) 1.05; 95% confidence interval (95% CI) 1.02-1.07; P < 0.001], abdominal or pelvic cancer (OR 2.84; 95% CI 1.35 5.97; P = 0.006), nephrotoxic chemotherapy within the previous 3 months (OR 3.84; 95% CI 1.67-8.84; P = 0.002) and sepsis (OR 2.74; 95% CI 1.30-5.77; P = 0.008). Renal recovery at Day 90 was inversely related to AKI severity. ICU, hospital and Day-90 mortality were 15, 29 and 37%, respectively. Factors independently associated with ICU mortality were: total serum protein (OR per 10 g/L, 0.44; 95% CI 0.23-0.86; P = 0.02) and SAPS II (OR 1.04; 95% CI 1.01-1.07; P = 0.02), while Day-90 mortality was associated with performance status 3-4 (OR 6.59; 95% CI 2.42 18; P < 0.001) and total serum protein (OR 0.60; 95% CI 0.38-0.94; P = 0.02). Conclusions: AKI in patients with solid tumours was frequent and renal recovery gradually decreased in proportion to AKI severity. However, AKI was not independently associated with a higher short-term mortality.

AB - Background: This study was conducted to assess the variation in prescription practices for systemic antimicrobial agents used for prophylaxis among pediatric patients hospitalized in 41 countries worldwide. Methods: Using the standardized Antibiotic Resistance and Prescribing in European Children Point Prevalence Survey protocol, a cross-sectional point-prevalence survey was conducted at 226 pediatric hospitals in 41 countries from October 1 to November 30, 2012. Results: Overall, 17693 pediatric patients were surveyed and 36.7% of them received antibiotics (n = 6499). Of 6818 inpatient children, 2242 (32.9%) received at least 1 antimicrobial for prophylactic use. Of 11899 prescriptions for antimicrobials, 3400 (28.6%) were provided for prophylactic use. Prophylaxis for medical diseases was the indication in 73.4% of cases (2495 of 3400), whereas 26.6% of prescriptions were for surgical diseases (905 of 3400). In approximately half the cases (48.7% [1656 of 3400]), a combination of 2 or more antimicrobials was prescribed. The use of broad-spectrum antibiotics (BSAs), which included tetracyclines, macrolides, lincosamides, and sulfonamides/trimethoprim, was high (51.8% [1761 of 3400]). Broad-spectrum antibiotic use for medical prophylaxis was more common in Asia (risk ratio [RR], 1.322; 95% confidence interval [CI], 1.202 1.653) and more restricted in Australia (RR, 0.619; 95% CI, 0.521-0.736). Prescription of BSA for surgical prophylaxis also varied according to United Nations region. Finally, a high percentage of surgical patients (79.7% [721 of 905]) received their prophylaxis for longer than 1 day. Conclusions: A high proportion of hospitalized children received prophylactic BSAs. This represents a clear target for quality improvement. Collectively speaking, it is critical to reduce total prophylactic prescribing, BSA use, and prolonged prescription. PMID- 29579263 TI - Etiology of Placental Plasmodium falciparum Malaria in African Women. AB - Plasmodium falciparum parasites causing placental malaria express the VAR2CSA type of the clonally variant antigen family erythrocyte membrane protein 1 (PfEMP1). This enables evasion of preexisting immunity and results in placental accumulation of infected erythrocytes. We present data on seasonal variation in levels of VAR2CSA-specific immunoglobulin G (IgG) and IgG specific for a placental malaria-unrelated PfEMP1 protein among Ghanaian women at their first antenatal visit. Our results indicate that placental malaria does not require recent exposure to infected mosquitoes, in contrast to malaria in general. This has implications for the impact of insecticide-treated bed nets on placental malaria incidence and for antenatal care in woman with preexisting immunity.

PMID- 29579265 TI - Imaging of the sacroiliac joints is important for diagnosing early axial spondyloarthritis but not all-decisive. AB - Objectives: To evaluate the contribution of the results of sacroiliac imaging to diagnosis and to the level of confidence in diagnosis in patients presenting with chronic back pain (CBP) and suspected of having axial spondyloarthritis (axSpA). Methods. Data from 513 patients from the SPondyloArthritisCaughtEarly cohort with CBP (?3 months, ?2 years, onset <45 years) were analysed after full diagnostic work-up. Rheumatologists were asked not only to provide a diagnosis before and after the imaging results had been provided to them, but also to provide the level of confidence of this diagnosis on an 11-point numerical scale. Results. Before imaging, 317/513 patients were diagnosed with axSpA. Of these patients, 178/317 (56%) did not have signs of sacroiliitis on either MRI or radiography, which led to the rheumatologist refuting the initial diagnosis of axSpA in 81/178 (46%) patients. Of the 196/513 patients without axSpA before imaging, 35/196 (18%) had signs of sacroiliitis on imaging. Subsequently, 28/35 (80%) patients were diagnosed with axSpA. Overall, imaging was incongruent with the diagnosis before imaging in 213 patients. This led to a change in diagnosis in 109/213 (51%), which corresponds to 21% (109/513) of all patients in the cohort. In general, diagnostic confidence increased by having imaging results available (from 6.2 to 7.4, P < 0.001). Conclusion: In patients with CBP suspected of having axSpA, sacroiliac imaging adds to the confidence in the final diagnosis. However, the number of changes in diagnosis suggests that imaging is important but not all-decisive in early axSpA diagnosis. PMID- 29579266 TI - Time-Dependent Postmortem Redistribution of Opioids in Blood and Alternative Matrices. AB - Forensic postmortem case interpretation can be challenging, in particular due to postmortem redistribution (PMR) phenomena. Recent studies have shown that computed tomography (CT)-guided collection of biopsy samples using a robotic arm (virtobot) provides a valuable tool for systematic studies on time-dependent PMR. Utilizing this strategy, several cases involving opioid use such as methadone, fentanyl, tramadol, codeine, oxycodone and hydrocodone were evaluated for time dependent concentration changes and potential redistribution mechanisms. Upon admission to the institute (t1), blood (femoral and right ventricle heart blood) and tissue biopsy samples (lung, kidney, liver, spleen, thigh muscle and adipose tissue) were collected utilizing CT-guided biopsy. Approximately 24 h later (t2; mean 28 +/- 15 h), during the autopsy, samples from the same body regions were collected manually and in addition brain tissue, gastric content, urine and left ventricle heart blood. Analysis was conducted with liquid chromatography tandem mass spectrometry. Significant time-dependent methadone concentration increases in femoral blood (pB) indicate the occurrence of PMR, however, ultimately not relevant for forensic interpretation. The main metabolite of methadone, 2 ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), showed a less significant trend for PMR. Redistribution by passive diffusion along the muscle-to-pB concentration gradient seems likely for methadone, but not for EDDP. Results for fentanyl suggest extensive PMR. Other opioids such as tramadol, codeine, hydrocodone and oxycodone showed no consistent trend for significant PMR. Overall, CT-guided biopsy sampling proved to be a valuable tool for the investigation of PMR mechanisms. PMID- 29579268 TI - An Overview of the Use of Bromelain-Based Enzymatic Debridement (Nexobrid(r)) in Deep Partial and Full Thickness Burns: Appraising the Evidence. AB - Recent introduction of rapid bromelain-based enzymatic debridement has been increasingly popular in its use in nonsurgical debridement in deep partial and full thickness burns. We designed this study to evaluate the evidence suggested by current studies on the perceived benefits of using Nexobrid(r) compared with traditional surgical standard of care in burns wound debridement. A comprehensive search on electronic databases Pubmed, Embase, and Web of Science was done to identify studies published between 1986 and 2017 involving the use of Nexobrid(r) in deep partial and full thickness burns. Studies were evaluated for proposed benefits and categorized under supporting evidence, contradicting evidence, and anecdotal opinions. Seven well-designed prospective studies met the inclusion comprising four randomized controlled trials. Six proposed benefits associated with the use of Nexobrid(r) were extracted including reduced time to complete debridement, need for surgery, area of burns excised, need for autograft, time to wound closure, and improved scar quality. Most proposed benefits have strong supporting evidences with minimal anecdotal opinions from controlled trials except the proposed improvement in scar quality and reduced time to wound healing that had at least three refuting evidence and one anecdotal evidence. Incidence of pain was also evaluated and was mainly anecdotal lacking formal objective assessment or cohort study. Despite the lack of literatures available, the benefits of Nexobrid(r) are evident in published randomized and single arm studies. Large number of studies is needed to aid further evaluating the proposed benefits of Nexobrid(r). PMID- 29579267 TI - Myosin XI-K is involved in root organogenesis, polar auxin transport, and cell division. AB - The interplay between myosin- and auxin-mediated processes was investigated by following root development in the triple myosin knockout mutant xi-k xi-1 xi-2 (3KO). It was found that the 3KO plants generated significantly more lateral and adventitious roots than the wild-type plants or the rescued plant line expressing functional myosin XI-K:yellow fluorescent protein (YFP; 3KOR). Using the auxin dependent reporter DR5:venus, a significant change in the auxin gradient toward the root tip was found in 3KO plants, which correlated with the loss of polar localization of the auxin transporter PIN1 in the stele and with the increased number of stele cells with oblique cell walls. Interestingly, myosin XI-K:YFP was localized to the cell division apparatus in the root and shoot meristems. In anaphase and early telophase, XI-K:YFP was concentrated in the midzone and the forming cell plate. In late telophase, XI-K:YFP formed a ring that overlapped with the growing phragmoplast. Myosin receptors MyoB1 and MyoB2 that are highly expressed throughout the plant were undetectable in dividing cells, suggesting that the myosin function in cell division relies on distinct adaptor proteins. These results suggest that myosin XIs are involved in orchestrating root organogenesis via effects on polar distribution of auxin responses and on cell division. PMID- 29579269 TI - Prediction of digestible and metabolizable energy of corn distillers dried grains with solubles for growing pigs using in vitro digestible nutrients. AB - The objective of this study was to develop prediction equations (EQS) that estimate DE and ME content of corn distillers dried grains with solubles (DDGS) using digestible (DIG) nutrients from in vitro or in vivo assays. Chemical composition data from 12 sources of corn DDGS were obtained using laboratory chemical analysis (LCA) and near infrared spectroscopy (NIRS). In vitro DM disappearance (IVDMD) from gastric and small intestine hydrolysis (IVDMDh), large intestine fermentation (IVDMDf), and total tract digestion (IVDMDt) were also determined along with in vivo apparent total tract digestibility (ATTD) of DM, CP, ether extract (EE), NDF, and ADF, and energy values (GE, DE, and ME). Correlation analysis was used to compare chemical composition from LCA with NIRS, and a stepwise selection of variables was performed using linear regression to establish DE and ME prediction EQS. Composition determined by NIRS did not correlate with values from LCA. Consequently, significance and R2 were poorer when using NIRS data as inputs to predict DE (P = 0.11; R2 = 0.23) and ME (P = 0.11; R2 = 0.24). However, when using LCA data, DE (P = 0.04; R2 = 0.35) and ME (P = 0.04; R2 = 0.52) estimates of corn DDGS obtained from prediction EQS had significant P values, but low R2. Better prediction of DE (P < 0.01; R2 = 0.83) and ME (P < 0.01; R2 = 0.76) was observed when using in vivo DIG nutrients as inputs (DM basis) for DE, kcal/kg = 854.5 + (3.6 * DIG DM, g/kg) + (3.7 * DIG EE, g/kg) + (2.0 * DIG NDF, g/kg) and ME, kcal/kg = 704.5 + (3.3 * DIG DM, g/kg) + (4.8 * DIG EE, g/kg) + (2.6 * DIG NDF, g/kg). In vitro DIG DM, but not in vitro DIG NDF, was selected for use in EQS (7) DE, kcal/kg = 6,383.6 - (42.5 * in vitro DIG DM, g/kg) + (35.4 * DIG EE, g/kg) and (8) ME, kcal/kg = 6,635.1 - (49.8 * in vitro DIG DM, g/kg) + (41.3 * DIG EE, g/kg), but the significance and accuracy for both DE (P = 0.07; R2 = 0.45) and ME (P = 0.05; R2 = 0.49) predictions was less using in vitro DIG nutrient values than using in vivo DIG nutrient values. If chemical composition was used to replace in vivo EE, along with in vitro DIG NDF and DM, the prediction EQS only used the concentration of ADF and EE as predictors instead of in vitro DIG NDF and DM. In conclusion, in vivo DIG NDF, DM, and EE are the best predictors for DE and ME content of corn DDGS for swine. Using NIRS to determine chemical composition, in vitro DIG NDF, and in vitro DIG DM did not result in accurate predictions of DE and ME. PMID- 29579270 TI - Analysis of segregation patterns of quadrivalent structures and the effect on genome stability during meiosis in reciprocal translocation carriers. AB - STUDY QUESTION: Do specific factors affect the segregation patterns of a quadrivalent structure and can the quadrivalent affect genome stability during meiosis? SUMMARY ANSWER: Meiotic segregation patterns can be affected by the carrier's gender and age, location of breakpoints and chromosome type, and the quadrivalent structure can increase genome instability during meiosis. WHAT IS KNOWN ALREADY: Carriers of reciprocal translocations have an increased genetic reproductive risk owing to the complex segregation patterns of a quadrivalent structure. However, the results of previous studies on the factors that affect segregation patterns seem to be contradictory, and the effect of a quadrivalent on genome stability during meiosis is unknown. STUDY DESIGN, SIZE, DURATION: We designed a retrospective study to analyze the segregation patterns of 24 chromosomes from reciprocal translocation and non-translocation patients. Data for 356 reciprocal translocation carriers and 53 patients with the risk to transmit monogenic inherited disorders (RTMIDs) undergoing PGD-single nucleotide polymorphism array analysis were collected. The study was performed between March 2014 and July 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: Segregation patterns of a quadrivalent in 1842 blastocysts from 466 assisted reproduction cycles of reciprocal translocation carriers were analyzed according to the location of chromosome breakpoints, the carrier's gender and age, and chromosome type. In addition, to analyze the effect of quadrivalent structure on genome stability, segregation products of chromosomes which are not involved in the translocation from translocation carriers were compared with those of 23 pairs of chromosomes in 318 blastocysts from 72 assisted reproduction cycles of patients with RTMIDs. MAIN RESULTS AND THE ROLE OF CHANCE: The percentage of adjacent-2 products with severe asymmetric quadrivalent was significantly higher than those with mild asymmetric quadrivalent (P = 0.020) while, in contrast, the incidence of 4:0/others was lower (P = 0.030). The frequencies of adjacent-1, adjacent-2 and 3:1 products differed between male and female carriers (P < 0.001, P = 0.015 and P = 0.001, respectively), and also for adjacent-1 and 4:0/others products in young versus older carriers (P = 0.04 and P = 0.002, respectively). In addition, adjacent-1 products of a quadrivalent with an acrocentric chromosome were significantly higher than those of a quadrivalent without an acrocentric chromosome (P = 0.001). Moreover, a quadrivalent could significantly increase the frequencies of abnormal chromosomes compared to patients with RTMIDs (P = 0.048, odds ratio (OR) = 1.43, 95% CI = 1.01-2.43), especially for the male carriers (P = 0.018, OR = 1.58, 95% CI = 1.08-2.25). In contrast, for older carriers, no difference was found in both aneuploidy and segmental anomalies compared to patients with RTMIDs. LIMITATIONS, REASONS FOR CAUTION: The study contained appropriate controls, yet the analysis was limited by a small number of control patients and embryos. WIDER IMPLICATIONS OF THE FINDINGS: Until now, there had been no definite report about the effect of quadrivalents on genome stability in reciprocal translocation carriers compared with control samples, and in the present study the large sample size ensured a detailed analysis of factors with a possible impact on segregation patterns. These data provide a better insight into the meiotic mechanisms involved in non-disjunction events in gametes from reciprocal translocation carriers. In addition, our results will help to provide each reciprocal translocation carrier couple undergoing PGD with more appropriate genetic counseling and a better understanding of the large numbers of abnormal embryos with chromosome aneuploidy.

PMID- 29579271 TI - Interleukin-34 is present at the fetal-maternal interface and induces immunoregulatory macrophages of a decidual phenotype in vitro. AB - STUDY QUESTION: Is the newly discovered cytokine interleukin (IL)-34 expressed at the human fetal-maternal interface in order to influence polarization of monocytes into macrophages of a decidual immunoregulatory phenotype? SUMMARY ANSWER: IL-34 was found to be present at the fetal-maternal interface, in both fetal placenta and maternal decidua, and it was able to polarize monocytes into macrophages of a decidual phenotype. WHAT IS KNOWN ALREADY: IL-34 was shown to bind to the same receptor as macrophage-colony stimulating factor (M-CSF), which has an important immunomodulatory role at the fetal-maternal interface, for example by polarizing decidual macrophages to an M2-like regulatory phenotype. IL 34 is known to regulate macrophage subsets, such as microglia and Langerhans cells, but its presence at the fetal-maternal interface is unknown. STUDY DESIGN, SIZE, DURATION: The presence of IL-34 at the fetal-maternal interface was evaluated by immunohistochemistry (IHC) and ELISA in placental and decidual tissues as well as in isolated trophoblast cells and decidual stromal cells obtained from first trimester elective surgical terminations of pregnancy (n = 49). IL-34 expression was also assessed in third trimester placental biopsies from women with (n = 21) or without (n = 15) pre-eclampsia. The effect of IL-34 on macrophage polarization was evaluated in an in vitro model of blood monocytes obtained from healthy volunteers (n = 14). In this model, granulocyte macrophage colony stimulating factor (GM-CSF) serves as a growth factor for M1-like polarization, and M-CSF as a growth factor for M2-like polarization. PARTICIPANTS/MATERIALS, SETTING, METHODS: First trimester placental and decidual tissues were obtained from elective pregnancy terminations. Placental biopsies were obtained from women with pre-eclampsia and matched controls in the delivery ward. Polarization of macrophages in vitro was determined by flow-cytometric phenotyping and secretion of cytokines and chemokines in cell-free supernatants by multiplex bead assay. MAIN RESULTS AND THE ROLE OF CHANCE: Our study shows that IL-34 is produced at the fetal-maternal interface by both placental cyto- and syncytiotrophoblasts and decidual stromal cells. We also show that IL-34, in vitro, is able to polarize blood monocytes into macrophages with a phenotype (CD14highCD163+CD209+) and cytokine secretion pattern similar to that of decidual macrophages. The IL-34-induced phenotype was similar, but not identical to the phenotype induced by M-CSF, and both IL-34- and M-CSF-induced macrophages were significantly different (P < 0.05-0.0001 depending on marker) from GM-CSF polarized M1-like macrophages. Our findings suggest that IL-34 is involved in the establishment of the tolerant milieu found at the fetal-maternal interface by skewing polarization of macrophages into a regulatory phenotype. LIMITATIONS, REASONS FOR CAUTION: Although it is clear that IL-34 is present at the fetal maternal interface and polarizes macrophages in vitro, its precise role in vivo remains to be established. WIDER IMPLICATIONS OF THE FINDINGS: The recently discovered cytokine IL-34 is present at the fetal-maternal interface and has immunomodulatory properties with regard to induction of decidual macrophages, which are important for a healthy pregnancy. Knowledge of growth factors related to macrophage polarization can potentially be translated to treatment of pregnancy complications involving dysregulation of this process.

AB - STUDY QUESTION: Can a discriminant threshold be determined for human sperm DNA oxidation? SUMMARY ANSWER: A discriminant threshold was found with 65.8% of 8 hydroxy-2'-deoxyguanosine (8-OHdG)-positive sperm cells and a mean intensity of fluorescence (MIF) of 552 arbitrary units. WHAT IS KNOWN ALREADY: Oxidative stress is known to interfere with sperm quality and fertilizing capacity. However, current practice does not include the routine determination of oxidative DNA damage in spermatozoa; optimized consensus protocols are lacking and no thresholds of normality have been established. STUDY DESIGN, SIZE, DURATION: Intra- and inter-method comparisons between four protocols (I-IV) were conducted to determine the most relevant and efficient means of assessing human sperm 8 OHdG content. Tests of assay repeatability, specificity, sensitivity and stability were performed to validate an optimized methodology for routine diagnostic use. PARTICIPANTS/MATERIALS, SETTING, METHODS: This prospective study compared three immuno-detection methods including immunocytochemistry, fluorescence microscopy and flow cytometry. Sperm DNA oxidation for 80 patients was determined relative to semen parameters and clinical conditions, using the selected immuno-detection protocol in comparison with a commercial kit. These patients (age 35 +/- 1 years: mean +/- SEM) presented with normozoospermic (n = 40) or altered parameters (necro- or/and astheno- or/and teratozoospermia or/and leukocytospermia). MAIN RESULTS AND THE ROLE OF CHANCE: Significant positive Pearson and Spearman correlations were determined for 8-OHdG values and sperm parameters using protocol III. A notable high and positive correlation was revealed for MIF with BMI and leukocyte concentration. Protocol III was the most discriminating method regarding assay repeatability, specificity, sensitivity, stability and reliability for sperm parameter alterations, in particular leukocytospermia according to parametric or non-parametric tests, effect-size determinations and factorial analysis such as principal component analysis and factor discriminant analysis. Of interest is that 39% of the subjects with 'pathological' sperm DNA oxidation values were normozoospermic. LIMITATIONS, REASONS FOR CAUTION: The oligozoospermic population was not evaluated in this study because insufficient material was available to carry out the comparisons. However, spermatozoa concentration was taken into account in the statistical analysis. WIDER IMPLICATIONS OF THE FINDINGS: Our study is the first validation of a protocol to determine a discriminant threshold for human sperm DNA oxidation. The protocol's detection accuracy for 8-OHdG human sperm DNA residues, stability over time, and relationship to human sperm quality were demonstrated. The assay should find application in the diagnosis of male factor infertility associated with oxidative stress.

AB - Femoral blood concentrations are usually used in postmortem toxicology to assess possible toxic effects of drugs. This includes QT-prolongation and other cardiac dysrhythmia, which could have been the cause of death. However, blood concentration is only a surrogate for the active site concentration, and therefore cardiac tissue concentration may provide a more accurate toxicological interpretation. Thus, cardiac tissue and femoral and cardiac blood concentrations were examined for eight frequently used QT-prolonging drugs (QTD) and their metabolites in a mentally ill population. In total, 180 cases were included from the Danish autopsy-based forensic study SURVIVE. The concentrations were analyzed using ultra-performance liquid chromatography coupled with tandem mass spectrometry utilizing stable isotopically labeled internal standards. The results showed that the cardiac tissue concentrations were significantly higher compared to femoral and cardiac blood concentrations, with two exceptions. The median cardiac tissue-to-femoral blood concentration ratio (Kb) ranged from 2.2 (venlafaxine) to 15 (nortriptyline). The inter-individual fold difference between the minimum and maximum Kb ranged from 2.6-fold (Z-hydroxynortriptyline) to 61 (venlafaxine). For 12 compounds, postmortem redistribution appeared to be minimal, whereas four compounds displayed some degree of postmortem redistribution. Citalopram and quetiapine were selected for in-depth analysis of the relation between the toxicological interpretation and femoral blood/cardiac tissue concentrations. Within this dataset, citalopram displayed a wide overlap in cardiac tissue concentrations (~50%) between non-toxic and toxic citalopram cases, as estimated from femoral blood concentrations. In contrast, quetiapine displayed no overlap in cardiac tissue concentrations between non-toxic and toxic quetiapine cases based on femoral blood concentrations. The implication of the citalopram finding is that possible intoxications can be overlooked when only considering femoral blood concentrations. Based on the present findings, non toxic cardiac tissue 10th-90th percentile concentration ranges were estimated for citalopram (0.93-4.4 mg/kg) and quetiapine (0.0073-0.60 mg/kg).

AB - Adult neurogenesis takes place in the brain subventricular zone (SVZ) in the lateral walls of lateral ventricles and subgranular zone (SGZ) in the hippocampal dentate gyrus (HDG), and functions to supply newborn neurons for normal brain functionality. Subchronic Mn exposure is known to disrupt adult neurogenesis in the SVZ. This study was designed to determine whether Mn exposure disturbed neurogenesis within the adult HDG. Adult rats (10 weeks old) received a single dose of bromodeoxyuridine (BrdU) at the end of 4-week Mn exposure to label the proliferating cells. Immunostaining and cell counting data showed that BrdU(+) cells in Mn-exposed HDG were about 37% lower than that in the control (p < .05). The majority of BrdU(+) cells were identified as Sox2(+) cells. Another set of adult rats received BrdU injections for 3 consecutive days followed by 2- or 4 week Mn exposure to trace the fate of BrdU-labeled cells in the HDG. The time course studies indicated that Mn exposure significantly reduced the survival rate (54% at 2 weeks and 33% at 4 weeks), as compared with that in the control (80% at 2 weeks and 51% at 4 weeks) (p < .01). A significant time-dependent migration of newborn cells from the SGZ toward the granule cell layer was also observed in both control and Mn-exposed HDG. Triple-stained neuroblasts and mature neurons further revealed that Mn exposure significantly inhibited the differentiation of immature neuroblasts into mature neurons in the HDG. Taken together, these observations suggest that subchronic Mn exposure results in a reduced cell proliferation, diminished survival of adult-born neurons, and inhibited overall neurogenesis in the adult HDG. Impaired adult neurogenesis is likely one of the mechanisms contribute to Mn-induced Parkinsonian disorder. PMID- 29579282 TI - New insights into the regulation of cell cycle. PMID- 29579281 TI - Occupational stress and coping mechanisms in crime scene personnel. AB - Background: Studies on occupational stress have shown that police officers (POs) are vulnerable to the effects of stress, demonstrated by increased risk of cardiometabolic diseases, which may be exacerbated by the use of maladaptive coping techniques. Although there is an abundance of research pertaining to stress in POs, little research has been done to assess a subset of law enforcement, crime scene personnel (CSP). Aims: To assess the stress levels, anxiety levels and coping mechanisms of CSP across the state of Texas. Methods: The Perceived Stress Scale (PSS), Police Stress Questionnaire (PSQ), and the Distress Thermometer were used to measure stress levels, the State-Trait Anxiety Inventory (STAI) was utilized to measure anxiety, and the Brief COPE questionnaire was used to measure coping mechanisms. Results: CSP (N = 76) surveyed reported both low stress and low anxiety for all measures used, with males reporting slightly higher stress and anxiety than females. Differences in coping mechanisms used by CSP were observed between males and females, but not between sworn officers and civilian workers. Female CSP used emotional support (P < 0.01), instrumental support (P < 0.05) and positive reframing (P < 0.05) as a coping mechanism significantly more often than males. Conclusions: The results suggest that adaptive coping mechanisms should be emphasized by those supervising CSP. With little research available on CSP, further evaluation of the type of stressors experienced by these members of law enforcement is warranted.

AB - Background: The Mantoux method of tuberculin skin testing has been used in tuberculosis (TB) screening of healthcare workers (HCWs) in the UK National Health Service (NHS) for many years. More recently, there have been problems with the supply of the Mantoux test solution presenting a challenge to its continued use. Aims: To review results of Mantoux testing and determine factors associated with positive Mantoux result, i.e. tuberculin reactivity, in NHS HCWs, with a view to streamlining the TB screening process. Methods: A retrospective descriptive study. We extracted data on HCW demographics, country of birth, previous stay or work in a high TB prevalence country, TB contact, Bacillus Calmette-Guerin (BCG) vaccination, previous tuberculin skin test (TST) and Mantoux results from the occupational health records of HCWs who had a Mantoux test during 1 January 2007 to 31 December 2010 inclusive. Results: We reviewed the records of 246 HCWs. Overall, 46% were Mantoux positive (defined as >=6 mm skin induration). Factors associated with positive Mantoux result were BCG vaccination [odds ratio (OR) 2.30; 95% confidence interval (CI) 1.14-4.66]; stay or work in a high TB prevalence country (OR 7.52; CI 2.76-20.46) and previous TST (OR 2.78; CI 1.25-6.19). Conclusions: BCG vaccination, stay or work in a high TB prevalence country and previous TST were associated with positive Mantoux results. These factors could be used to predict Mantoux results, with the potential of substituting Mantoux testing. PMID- 29579284 TI - Attractor landscape analysis of the cardiac signaling network reveals mechanism based therapeutic strategies for heart failure. AB - Apoptosis and hypertrophy of cardiomyocytes are the primary causes of heart failure (HF), a global leading cause of death, and are regulated through the complicated intracellular signaling network, limiting the development of effective treatments due to its complexity. To identify effective therapeutic strategies for HF at a system level, we develop a large-scale comprehensive mathematical model of the cardiac signaling network by integrating all available experimental evidence. Attractor landscape analysis of the network model identifies distinct sets of control nodes that effectively suppress apoptosis and hypertrophy of cardiomyocytes under ischemic or pressure overload-induced HF, the two major types of HF. Intriguingly, our system-level analysis suggests that intervention of these control nodes may increase the efficacy of clinical drugs for HF and, of most importance, different combinations of control nodes are suggested as potentially effective candidate drug targets depending on the types of HF. Our study provides a systematic way of developing mechanism-based therapeutic strategies for HF. PMID- 29579285 TI - Sublethal Effects of Some Insecticides on Functional Response of Habrobracon hebetor (Hymneoptera: Braconidae) When Reared on Two Lepidopteran Hosts. AB - The effects of four commonly used pesticides, diazinon (EC 60%), phosalone (EC 35%), fipronil (Granular formulation 0.2%), and pyriproxifen (EC 10%), on functional response of Habrobracon hebetor (Say) (Hymenoptera: Braconidae) were investigated using two lepidopteran hosts, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) and Heliothis viriplaca (Hufnagel) (Lepidoptera: Noctuidae). Laboratory bioassays determined diazinon and fipronil as highly toxic insecticides for all developmental stages of the parasitoid, while the acute toxicity of phosalone and pyriproxyfen was moderate to very low depending on the life-stage studied. Larval, pupal, and adult stages of the parasitoid were exposed to sublethal concentrations (LC30) of insecticides, and the newly mated females were used to study functional response of the parasitoid to different host densities. With a single exception, a type II functional response was found for control and all insecticide treatments on all life stages and both host species. All insecticides tended to decrease the asymptote of the functional response curve and the maximum parasitism rate, probably by negatively affecting the searching efficiency (a') of the parasitoid. These results indicate that the control efficiency of parasitoids may be negatively affected by sublethal doses of pesticides, even though the type of functional response remains unchanged. As a potential solution, appropriate timing of pesticide application is required to avoid the antagonistic interactions with natural enemies under integrated management programs. PMID- 29579287 TI - Prospective Tractography-Based Targeting for Improved Safety of Focused Ultrasound Thalamotomy. AB - BACKGROUND: Focused ultrasound thalamotomy (FUS-T) was recently approved for the treatment of refractory essential tremor (ET). Despite its noninvasive approach, FUS-T reinitiated concerns about the adverse effects and long-term efficacy after lesioning. OBJECTIVE: To prospectively assess the outcomes of FUS-T in 10 ET patients using tractography-based targeting of the ventral intermediate nucleus (VIM). METHODS: VIM was identified at the intercommissural plane based on its neighboring tracts: the pyramidal tract and medial lemniscus. FUS-T was performed at the center of tractography-defined VIM. Tremor outcomes, at baseline and 3 mo, were assessed independently by the Tremor Research Group. We analyzed targeting coordinates, clinical outcomes, and adverse events. The FUS-T lesion location was analyzed in relation to unbiased thalamic parcellation using probabilisitic tractography. Quantitative diffusion-weighted imaging changes were also studied in fiber tracts of interest. RESULTS: The tractography coordinates were more anterior than the standard. Intraoperatively, therapeutic sonications at the tractography target improved tremor (>50% improvement) without motor or sensory side effects. Sustained improvement in tremor was observed at 3 mo (tremor score: 18.3 +/- 6.9 vs 8.1 +/- 4.4, P = .001). No motor weakness and sensory deficits after FUS-T were observed during 6-mo follow-up. Ataxia was observed in 3 patients. FUS-T lesions overlapped with the VIM parcellated with probablisitic tractography. Significant microstructural changes were observed in the white matter connecting VIM with cerebellum and motor cortex. CONCLUSION: This is the first report of prospective VIM targeting with tractography for FUS-T. These results suggest that tractography-guided targeting is safe and has satisfactory short-term clinical outcomes. PMID- 29579286 TI - Involvement of Heparanase in the Pathogenesis of Mesothelioma: Basic Aspects and Clinical Applications. AB - Background: Mammalian cells express a single functional heparanase, an endoglycosidase that cleaves heparan sulfate and thereby promotes tumor metastasis, angiogenesis, and inflammation. Malignant mesothelioma is highly aggressive and has a poor prognosis because of the lack of markers for early diagnosis and resistance to conventional therapies. The purpose of this study was to elucidate the mode of action and biological significance of heparanase in mesothelioma and test the efficacy of heparanase inhibitors in the treatment of this malignancy. Methods: The involvement of heparanase in mesothelioma was investigated by applying mouse models of mesothelioma and testing the effect of heparanase gene silencing (n = 18 mice per experiment; two different models) and heparanase inhibitors (ie, PG545, defibrotide; n = 18 per experiment; six different models). Synchronous pleural effusion and plasma samples from patients with mesothelioma (n = 35), other malignancies (12 non-small cell lung cancer, two small cell lung carcinoma, four breast cancer, three gastrointestinal cancers, two lymphomas), and benign effusions (five patients) were collected and analyzed for heparanase content (enzyme-linked immunosorbent assay). Eighty-one mesothelioma biopsies were analyzed by H-Score for the prognostic impact of heparanase using immunohistochemistry. All statistical tests were two-sided. Results: Mesothelioma tumor growth, measured by bioluminescence or tumor weight at termination, was markedly attenuated by heparanase gene silencing (P = .02) and by heparanase inhibitors (PG545 and defibrotide; P < .001 and P = .01, respectively). A marked increase in survival of the mesothelioma-bearing mice (P < .001) was recorded. Heparanase inhibitors were more potent in vivo than conventional chemotherapy. Clinically, heparanase levels in patients' pleural effusions could distinguish between malignant and benign effusions, and a heparanase H-score above 90 was associated with reduced patient survival (hazard ratio = 1.89, 95% confidence interval = 1.09 to 3.27, P = .03). Conclusions: Our results imply that heparanase is clinically relevant in mesothelioma development. Given these preclinical and clinical data, heparanase appears to be an important mediator of mesothelioma, and heparanase inhibitors are worthy of investigation as a new therapeutic modality in mesothelioma clinical trials.

Haemophilus influenzae serotype b occurred in vaccinated, healthy children with comparable disease course. PMID- 29579289 TI - Comparative efficacy of individual renin-angiotensin system inhibitors on major renal outcomes in diabetic kidney disease: a network meta-analysis. AB - Background: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are two drug classes with well-documented renal protective effects. However, whether there is any difference among individual drugs remains unknown. In this study, we aimed to compare the efficacy of individual ACEIs/ARBs on major renal outcomes in adults with diabetic kidney disease (DKD). Methods: We conducted a Bayesian-framework network meta-analysis with a random effects model. We searched PubMed, Embase, Scopus, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov for clinical trials of ACEIs or ARBs as monotherapy compared with other conventional antihypertensive drugs or placebo. Primary outcomes were end-stage renal disease (ESRD) and albuminuria/proteinuria (including change in albuminuria/proteinuria, progression to macroalbuminuria and remission to normoalbuminuria). Secondary outcome was doubling of serum creatinine levels. We also assessed for hyperkalemia, cough and angioedema/edema. International prospective register of systematic reviews (PROSPERO) registration CRD42016036997. Results: A total of 100 studies with data for 22 365 DKD patients, the majority of whom had type 2 diabetes, were included. Individual ACEIs and ARBs at goal doses showed no significant differences in ESRD and doubling of serum creatinine levels. They also shared similar effects on albuminuria/proteinuria reduction and progression or remission of albuminuria. When combining three outcomes of albuminuria/proteinuria as a single endpoint, most ACEIs/ARBs consistently showed favorable antiproteinuric effect, with little difference in the possibility of being the superior treatment for improving albuminuria/proteinuria. Primary outcomes did not change substantially in meta regressions and sensitivity analyses. Findings were limited by lack of dose equivalence and paucity of data for some outcomes. Conclusions: Based on the available evidence, individual ACEIs and ARBs at goal doses appeared to have no or little differences in their effect on major renal outcomes. PMID- 29579290 TI - The impact of outpatient acute kidney injury on mortality and chronic kidney disease: a retrospective cohort study. AB - Background: Acute kidney injury (AKI) has been extensively studied in hospital settings. Limited data exist regarding outcomes for patients with outpatient AKI who are not subsequently admitted. We investigated whether outpatient AKI, defined by a 50% increase in creatinine (Cr), is associated with increased mortality and renal events. Methods: In this retrospective study, outpatient serum Cr values from adults receiving primary care at a health system during an 18-month exposure period were used to categorize patients into one of five groups (no outpatient AKI, outpatient AKI with recovery, outpatient AKI without recovery, outpatient AKI without repeat Cr and no Cr). Principal outcomes of all cause mortality and renal events (50% decline in estimated glomerular filtration rate to <30 mL/min/1.73 m2) were examined using Cox proportional hazards models. Results: Among 384 869 eligible patients, 51% had at least one Cr measured during the exposure period. Outpatient AKI occurred in 1.4% of patients while hospital AKI occurred in only 0.3% of patients. The average follow-up was 5.3 years. Outpatient AKI was associated with an increased risk of all-cause mortality {adjusted hazard ratio [aHR] 1.90 [95% confidence interval (CI) 1.76-2.06]} and results were consistent across all AKI groups. Outpatient AKI was also associated with an increased risk of renal events [aHR 1.33 (95% CI 1.11-1.59)], even among those who recovered. Conclusions: Outpatient AKI is more prevalent than inpatient AKI and is a risk factor for all-cause mortality and renal events, even among those who recover kidney function. Further research is necessary to determine risk factors and identify strategies for preventing outpatient AKI.

PMID- 29579292 TI - Do atmospheric CO2 concentration increase, climate and forest management affect iWUE of common beech? Evidences from carbon isotope analyses in tree rings. AB - Beech is one of the most important forest tree species in Europe, hence possible adverse factors affecting its physiology and productivity can have strong ecological and economic impacts. In this context, four beech forests along a latitudinal gradient from southern Apennines to middle European lowlands were selected for chronological determinations of carbon isotope composition (delta13C) in tree-ring cellulose. The main objectives of this study were to assess (i) the effect of climate on the carbon signature of tree-ring cellulose (delta13C); (ii) the physiological response to recent CO2 concentration increment and to climatic variation; and (iii) the relationship between intrinsic water-use efficiency (iWUE, here the average long-term ratio of net photosynthesis to stomatal conductance) and growth of trees in different sites since 1950. Our results demonstrated that site climatic conditions peculiarly affect delta13C. In northern sites, a climatic control of summer precipitation and temperature on stomatal conductance was demonstrated by their opposite correlations with delta13C, negative and positive, respectively. Furthermore, an 'earliness effect' was suggested by a significant relationship between spring temperature and delta13C in the coldest sites and by a positive one between winter temperature and delta13C in the warmest ones. In all the study sites, during the maturity phase, a positive correlation between the increment of CO2 and iWUE was observed, due to an active response of trees to CO2 increment. This increment of CO2 was the main driver of the long term increasing trend of iWUE, resulting by an active response of trees to CO2 fertilization. Moreover, precipitation mostly influences positively and negatively the inter-annual variations of iWUE of the southernmost and northernmost sites, respectively. Overall, we observed a mean increment of 40% of iWUE. Moreover, the sensitivity of iWUE to the increase of CO2 was different between the northernmost and southernmost sites. Increasing iWUE was correlated to growth in the two sites during the release phase and we hypothesize a positive effect of silvicultural treatments. PMID- 29579293 TI - Engaging workplace representatives in research: what recruitment strategies work best? AB - Background: Workplaces are key stakeholders in work and health but little is known about the methods used to recruit workplace representatives (WRs), including managers, occupational health advisers and colleagues, to externally funded healthcare research studies. Aims: To detail the strategies used in recruiting WRs from three areas of the UK to a qualitative study concerning their experience of employees undergoing hip or knee replacement, to compare the strategies and inform recruitment methods for future studies. Methods: Six strategies were used to recruit WRs from organizations of different sizes and sectors. Data on numbers approached and responses received were analysed descriptively. Results: Twenty-five WRs were recruited. Recruitment had to be extended outside the main three study areas, and took several months. It proved more difficult to recruit from non-service sectors and small- and medium-sized enterprises. The most successful strategies were approaching organizations that had participated in previous research studies, or known professionally or personally to team members. Conclusions: Recruiting a diverse sample of WRs to healthcare research requires considerable resources and persistence, and a range of strategies. Recruitment is easier where local relationships already exist; the importance of building and maintaining these relationships cannot be underestimated. However, the potential risks of bias and participant fatigue need to be acknowledged and managed. Further studies are needed to explore how WRs can be recruited to health research, and to identify the researcher effort and costs involved in achieving unbiased and representative samples. PMID- 29579294 TI - Topical Review: Perfectionism and Pediatric Chronic Pain: Theoretical Underpinnings, Assessment, and Treatment. AB - Objective: To use the biopsychosocial model and current literature to clarify conceptual underpinnings between chronic pain and perfectionism in youth, provide recommendations for assessment and treatment of co-existing perfectionism and chronic pain conditions, and suggest a research agenda. Methods: Current literature is used to identify biopsychosocial factors common between pediatric chronic pain and perfectionism, preliminary research findings are presented, and suggestions are made for research that will help inform inclusion and adaptations of assessment tools and interventions to address perfectionism. Results: Biopsychosocial factors that may contribute to the observed relationship between chronic pain and perfectionism seen in many youth are identified. For example, cognitive factors known to be associated with perfectionism (e.g., rumination) may also contribute to pain-related catastrophizing and disability. Biopsychosocial factors may serve as mediating variables between perfectionism and pain-related outcomes among youth with chronic pain and their parents. Conclusions: Research assuming a biopsychosocial perspective is needed to clarify observed links between chronic pain and perfectionism in youth. Findings related to the characterization of perfectionism in pediatric chronic pain will inform how assessment and treatment tools can better identify and address perfectionism.

AB - The aim of this article was to observe the intracellular insulin content of islets isolated from severely scalded and Exendin-4-treated rats and to evaluate the stimulation of insulin mRNA synthesis and secretion by beta cells at different glucose concentrations and during different periods of time. A 50% TBSA full-thickness scalded rat model was used. Rats were treated with Exendin-4, followed by islet isolation and functional measurements. Serum was collected for detection of serum insulin, glucose, and glucagon levels. Intracellular insulin content was determined by transmission electron microscopy. Isolated islets were incubated with different glucose concentrations for 1 or 24 hours to assess the effect of scalding with or without Exendin-4 treatment on functional parameters. Insulin secretion was analyzed by enzyme-linked immunosorbent assay. Intracellular insulin and proinsulin content were analyzed by immunoprecipitation. Islet preproinsulin mRNA expression was examined by real time polymerase chain reaction. Transmission electron microscopy analyses showed that severe thermal injury significantly reduced the number of insulin granules per micrometer2. Insulin secretion and intracellular insulin and proinsulin levels were markedly reduced in islets stimulated with different glucose concentrations; chronic high-glucose-stimulated islet preproinsulin mRNA expression was also impaired. Exendin-4 treatment after thermal trauma improved the number of intracellular insulin granules. Exendin-4 improved both insulin secretion and intracellular insulin reserves under different glucose stimulation conditions. Islet insulin mRNA expression was also restored by Exendin-4 treatment. Exendin-4 can restore the islet beta cell insulin reserve following severe scald injury and may also improve insulin secretion, insulin reserve, and mRNA expression in islet beta cells. PMID- 29579299 TI - Overexpression of PeMIPS1 confers tolerance to salt and copper stresses by scavenging reactive oxygen species in transgenic poplar. AB - Myo-inositol is a vital compound in plants. As the key rate-limiting enzyme in myo-inositol biosynthesis, l-myo-inositol-1-phosphate synthase (MIPS) is regarded as a determinant of the myo-inositol content in plants. The up-regulation of MIPS genes can increase the myo-inositol content, thereby enhancing the plant's resistance to a variety of stresses. However, there are few reports on the roles of myo-inositol and the identification of MIPS in woody trees. In this study, a MIPS gene, named as PeMIPS1, was characterized from Populus euphratica Oliv. The heterologous expression of PeMIPS1 compensated for inositol production in the yeast inositol auxotrophic mutant ino1 and the phenotypic lesions of the atmips1 2 mutant, an Arabidopsis MIPS1 knock-out mutant. A subcellular location analysis showed that the PeMIPS1-GFP fusion was localized in the nucleus and cytoplasm, but not in the chloroplasts, indicating that PeMIPS1 represented the cytosolic form of MIPS in P. euphratica. Interestingly, PeMIPS1 was not only inducible by drought and high salinity, but also by CuSO4 treatment. The transgenic poplar lines overexpressing PeMIPS1 had greater plant heights, shoot biomasses and survival rates than the wild type during the salt- or copper-stress treatment, and this was accompanied by an increase in the myo-inositol content. The overexpression of PeMIPS1 resulted in the increased activities of antioxidant enzymes and the accumulation of ascorbate, a key nonenzymatic antioxidant in plant, which partly accounted for the enhanced reactive oxygen species-scavenging capacity and the lowered hydrogen peroxide and malondialdehyde levels in the transgenic poplar. To the best of our knowledge, this study is the first to report the roles of MIPS genes in the tolerance to copper stress. PMID- 29579300 TI - Forgiveness, spirituality and love: thematic analysis of last statements from Death Row, Texas (2002-17). AB - Background: Psychological features associated with execution are not fully understood. Aims: To analyse demographics of individuals executed in Texas and investigate whether there has been any change in common themes and psychological factors evident in last statements before execution between 2002 and 2017. Design: Analysis of last statements from Death Row, Texas. Methods: We (a) studied themes and psychological factors in last statements in Texas between August 2011 and May 2017; and (b) combined our 2011-17 data with our previous data (2002-06 and 2006-11) to present an overall analysis of last statements from 2002 to 2017. Results: Between April 2002 and May 2017 (279 executions; 240 last statements), the execution rate in Texas fell from 25 per year to 12; median time on death row increased from 108.5 months to 149.5; median age at execution increased from 38 years to 40.5; and the proportion of offences involving multiple victims rose from 28.4% to 47.1%. The most common themes in last statements were love (78%), spirituality (58%), regret (35%) and apology (35%). The most common psychological factors were identification-egression (51%), unbearable psychological pain (47%) and rejection-aggression (40%). Two themes (forgiveness, use of poetry/literature) and three psychological factors (inability to adjust, interpersonal relations, identification-egression) became less common. Conclusions: Between 2002 and 2017, executed prisoners in Texas became fewer and older, spent longer on death row and had committed more serious offences. Themes of love and spirituality were constants, but requests for forgiveness declined. PMID- 29579301 TI - Functional characteristics of phenolic compounds accumulated in young leaves of two subtropical forest tree species of different successional stages. AB - The abundance of phenolic compounds (including anthocyanins) in leaves is associated with photosynthetic performance, but the regulatory mechanism is unclear. Schima superba Gardn. et Champ. and Cryptocarya concinna Hance., which exhibit distinct anthocyanin accumulation patterns, are dominant tree species in the early- and late-successional stages, respectively, of subtropical forests in China. RNA-seq and analyses of phenolic concentrations, antioxidant capacity and photosynthetic characteristics were performed on young and mature leaves of these two species under contrasting light conditions. The high-light-acclimated young leaves of S. superba and C. concinna and low-light-acclimated young leaves of C. concinna were red. These red leaves had higher ratios of electron transport rate to gross photosynthesis (ETR:Pgross) and total antioxidant capacity to chlorophyll (TAC:Chl) than did the green leaves, regardless of light conditions. In addition, the red leaves had a higher expression level of the UDP glucose:flavonoid 3-O-glucosyltransferase (UFGT) gene than did the green leaves, irrespective of light conditions. Total antioxidant capacity was positively correlated with flavonoid content in C. concinna leaves and with total phenolic content in leaves of both species under both high and low light. Consistent with the measurements of photosynthetic performance and flavonoids:Chl ratio, photosynthesis-related genes were extensively downregulated and flavonoid-pathway related genes were extensively upregulated in young leaves relative to mature leaves. Under high and low light, both non-photochemical quenching and TAC:Chl, which serve as different types of photoprotective tools, were enhanced in young leaves of S. superba, whereas only TAC:Chl was enhanced in young leaves of C. concinna. Our results indicate that the biosynthesis of phenolic compounds in young leaves is likely enhanced by an imbalance between photosynthetic electron supply and demand and that flavonoids play a larger role in meditating photoprotection in late-successional species than in early-successional ones. PMID- 29579276 TI - Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: a pooled analysis of 1018 population-based measurement studies with 88.6 million participants. AB - Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probit-transformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the high-income Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups. PMID- 29579302 TI - Community-acquired pneumonia and Gram-negative bacilli in Cambodia-incidence, risk factors and clinical characteristics. AB - Background: In Western settings, community-acquired pneumonia (CAP) due to Gram negative bacilli (GNB) is relatively rare. Previous studies from Asia, however, indicate a higher prevalence of GNB in CAP, but data, particularly from Southeast Asia, are limited. Methods: This is a prospective observational study of 1451 patients >=15 y of age with CAP from two hospitals in Cambodia between 2007 and 2010. The proportion of GNB was estimated. Risk factors and clinical characteristics of CAP due to GNB were assessed using logistic regression models. Results: The prevalence of GNB was 8.6% in all CAP patients and 15.8% among those with a valid respiratory sample. GNB infection was independently associated with diabetes, higher leucocyte count and CAP severity. Mortality was higher in patients with CAP due to GNB. Conclusions: We found a high proportion of GNB in a population hospitalized for CAP in Cambodia. Given the complex antimicrobial sensitivity patterns of certain GNBs and the rapid emergence of multidrug resistant GNB, microbiological laboratory capacity should be strengthened and prospective clinical trials comparing empiric treatment algorithms according to the severity of CAP are needed. PMID- 29579303 TI - Impact of the bicuspid aortic valve on aortic root haemodynamics: three dimensional computed fluid dynamics simulation. AB - OBJECTIVES: The aim was to evaluate the impact of a bicuspid aortic valve (BAV) on local shear stress and on the pressure profile on the elements of the aortic root (AoR). METHODS: The experiment setup included a BAV with aortic valve stenosis (n = 5 pigs, 67 +/- 3.5 kg) and insufficiency (n = 5 pigs, 66.7 +/- 4.4 kg). By implanting 6 high-fidelity microsonometric crystals in each AoR, we determined the 3-dimensional (3D) geometry of the AoR. Experimental and geometric data were used to create a 3D time- and pressure-dependent computed fluid dynamic model of the AoR with the BAV. RESULTS: 3D AoR geometry was determined by AoR tilt (alpha) and rotation angle (beta). Both values were maximal at the end of diastole: 24.41 +/- 1.70 degrees (alpha) and 20.90 +/- 2.11 degrees (beta) for BAV with stenosis and 31.92 +/- 11.51 degrees (alpha) and 20.84 +/- 9.80 degrees (beta) for BAV with insufficiency and minimal at peak ejection 23.42 +/- 1.65 degrees (alpha), 20.38 +/- 1.61 degrees (beta) for stenosis and 26.62 +/- 7.86 degrees (alpha), 19.79 +/- 8.45 degrees (beta) for insufficiency. In insufficiency, low shear stress of 0-0.08 Pa and moderate pressure (60-80 mmHg) were present. In BAV with stenosis, low shear stress of 0-0.5 Pa and moderate pressure (0-20 mmHg) were present at diastole; at peak ejection high shear stress >2 Pa and elevated pressure of >80 mmHg were present. CONCLUSIONS: In a BAV with aortic valve stenosis, the haemodynamics are less favourable. The elevated pressure with elevated shear stress may over the long term promote degenerative processes in the leaflets and consequently valve function failure. PMID- 29579304 TI - Molecular cloning and characterization of a brassinosteriod biosynthesis-related gene PtoDWF4 from Populus tomentosa. AB - Brassinosteroids (BRs) as steroid hormones play an important role in plant growth and development. However, little is known about how BRs affect secondary wall biosynthesis in woody plants. In this study, we cloned and characterized PtoDWF4, a homologus gene of Arabidopsis DWF4 encoding a cytochrome P450 protein, from Populus tomentosa. qRT-PCR analysis showed that PtoDWF4 was highly expressed in stems, especially in xylem. Overexpression of PtoDWF4 (PtoDWF4-OE) in poplar promoted growth rate and biomass yield, increased area and cell layers of xylem. Transgenic plants showed a significant increase in plant height and stem diameter compared with the wild type. In contrast, the CRISPR/Cas9-generated mutation of PtoDWF4 (PtoDWF4-KO) resulted in significantly decreased biomass production in transgenic plants. Further studies revealed that constitutive expression of PtoDWF4 up-regulated the expression of secondary cell wall (SCW) biosynthesis related genes, whereas knock-out of PtoDWF4 down-regulated their expression. Quantitative analysis of cell wall components showed a significant increase in PtoDWF4-OE lines but a reduction in PtoDWF4-KO lines compared with wild-type plants. Taken together, our results indicate that PtoDWF4 plays a positive role in improving growth rate and elevating biomass production in poplar. PMID- 29579305 TI - Seizure outcomes of supratentorial brain tumor resection in pediatric patients. AB - Background: This study aims to identify the prevalence of and risk factors for seizure development after supratentorial brain tumor resection in pediatric patients. This could be used to guide the postoperative management and usage of anti-epileptic drugs (AEDs). Methods: Retrospective study was conducted for patients between 0 and 21 years with supratentorial tumor resection between 2005 and 2015 at a single institution. Results: Two hundred patients (114 males/86 females) were identified. Median age at resection (+/-SD) was 9.025 +/- 5.720 years and mean follow-up was 4 +/- 2 years. Resection was gross total in 82 patients (41%) and partial in 118 patients (59%); 66 patients (33%) experienced preoperative seizures, and 67 patients (34%) experienced postoperative seizures; 18 patients (27%) had early seizures, and 49 patients (73%) had late seizures. Univariate analysis identified risk factors for postoperative seizures as: preoperative seizures (P < 0.001), age less than 2 years (P = 0.003), temporal location (P < 0.001), thalamic location (P = 0.017), preoperative hyponatremia (P = 0.017), World Health Organization grade (P = 0.008), and pathology (P = 0.005). Multivariate regression identified 5 robust risk factors: temporal location (odds ratio [OR] 4.7, 95% CI: 1.7-13.3, P = 0.003), age <2 years (OR 3.9, 95% CI: 1.0 15.4; P = 0.049), preoperative hydrocephalus (OR 3.8, 95% CI: 1.5-9.4; P = 0.005), preoperative seizure (OR 2.8, 95% CI: 1.2-6.5; P = 0.016) and parietal location (OR 0.25, 95% CI: 0.06-0.99; P = 0.049). Extent of resection did not correlate with seizure development (P > 0.05). Conclusions: This study reveals 5 risk factors for postoperative seizures after resection of supratentorial tumors. These factors should be considered in postoperative management of these patients. PMID- 29579306 TI - A Novel Multifunctional C-23 Oxidase, CYP714E19, is Involved in Asiaticoside Biosynthesis. AB - Centella asiatica is widely used as a medicinal plant due to accumulation of the ursane-type triterpene saponins asiaticoside and madecassoside. The molecular structure of both compounds suggests that they are biosynthesized from alpha amyrin via three hydroxylations, and the respective Cyt P450-dependent monooxygenases (P450 enzymes) oxidizing the C-28 and C-2alpha positions have been reported. However, a third enzyme hydroxylating C-23 remained elusive. We previously identified 40,064 unique sequences in the transcriptome of C. asiatica elicited by methyl jasmonate, and among them we have now found 149 unigenes encoding putative P450 enzymes. In this set, 23 full-length cDNAs were recognized, 13 of which belonged to P450 subfamilies previously implicated in secondary metabolism. Four of these genes were highly expressed in response to jasmonate treatment, especially in leaves, in accordance with the accumulation patterns of asiaticoside. The functions of these candidate genes were tested using heterologous expression in yeast cells. Gas chromatography-mass spectrometry (GC-MS) analysis revealed that yeast expressing only the oxidosqualene synthase CaDDS produced the asiaticoside precursor alpha-amyrin (along with its isomer beta-amyrin), while yeast co-expressing CaDDS and CYP716A83 also contained ursolic acid along with oleanolic acid. This P450 enzyme thus acts as a multifunctional triterpenoid C-28 oxidase converting amyrins into corresponding triterpenoid acids. Finally, yeast strains co-expressing CaDDS, CYP716A83 and CYP714E19 produced hederagenin and 23-hydroxyursolic acid, showing that CYP714E19 is a multifunctional triterpenoid oxidase catalyzing the C-23 hydroxylation of oleanolic acid and ursolic acid. Overall, our results demonstrate that CaDDS, CYP716A83 and CYP714E19 are C. asiatica enzymes catalyzing consecutive steps in asiaticoside biosynthesis. PMID- 29579307 TI - A threonyl-tRNA synthetase-like protein has tRNA aminoacylation and editing activities. AB - TARS and TARS2 encode cytoplasmic and mitochondrial threonyl-tRNA synthetases (ThrRSs) in mammals, respectively. Interestingly, in higher eukaryotes, a third gene, TARSL2, encodes a ThrRS-like protein (ThrRS-L), which is highly homologous to cytoplasmic ThrRS but with a different N-terminal extension (N-extension). Whether ThrRS-L has canonical functions is unknown. In this work, we studied the organ expression pattern, cellular localization, canonical aminoacylation and editing activities of mouse ThrRS-L (mThrRS-L). Tarsl2 is ubiquitously but unevenly expressed in mouse tissues. Different from mouse cytoplasmic ThrRS (mThrRS), mThrRS-L is located in both the cytoplasm and nucleus; the nuclear distribution is mediated via a nuclear localization sequence at its C-terminus. Native mThrRS-L enriched from HEK293T cells was active in aminoacylation and editing. To investigate the in vitro catalytic properties of mThrRS-L accurately, we replaced the N-extension of mThrRS-L with that of mThrRS. The chimeric protein (mThrRS-L-NT) has amino acid activation, aminoacylation and editing activities. We compared the activities and cross-species tRNA recognition between mThrRS-L-NT and mThrRS. Despite having a similar aminoacylation activity, mThrRS-L-NT and mThrRS exhibit differences in tRNA recognition and editing capacity. Our results provided the first analysis of the aminoacylation and editing activities of ThrRS L, and improved our understanding of Tarsl2. PMID- 29579308 TI - The effect of albendazole treatment on non-seizure outcomes in patients with symptomatic neurocysticercosis. AB - Background: There is little information about the impact of anthelminthic treatment on clinical symptoms other than seizures in neurocysticercosis (NC). We investigated the effect of albendazole on non-seizure symptoms experienced by patients with NC. Methods: Data are from a randomized controlled trial comparing albendazole plus prednisone with placebo plus prednisone for treatment of NC among 173 patients with active or transitional NC cysts and new-onset symptoms. We performed negative binomial regression to examine the number of follow-up visits when a symptom was reported, logistic regression to examine the probability of experiencing the symptom and Cox proportional hazards models to examine the time to first reporting the symptom. Results: Eighty-five percent of patients reported at least one non-seizure symptom at baseline. Those treated with albendazole had significantly lower odds of memory loss and/or confusion during months 1-24 (odds ratio [OR] 0.42, p=0.037) and significantly increased odds of anxiety and/or depression during months 1-12 (OR 1.87, p=0.049). No treatment difference existed in experiencing symptoms in general or in experiencing headaches, limb weakness or gait disturbances, vomiting, nausea and/or stomach pain or visual disturbances over the follow-up period. Conclusions: While the prevalence of non-seizure symptoms was high, albendazole treatment was associated with only two significant differences in the non-seizure symptoms over follow-up. Further research is needed to identify strategies to reduce the long-term symptom burden in patients with NC. PMID- 29579309 TI - ViFi: accurate detection of viral integration and mRNA fusion reveals indiscriminate and unregulated transcription in proximal genomic regions in cervical cancer. AB - The integration of viral sequences into the host genome is an important driver of tumorigenesis in many viral mediated cancers, notably cervical cancer and hepatocellular carcinoma. We present ViFi, a computational method that combines phylogenetic methods with reference-based read mapping to detect viral integrations. In contrast with read-based reference mapping approaches, ViFi is faster, and shows high precision and sensitivity on both simulated and biological data, even when the integrated virus is a novel strain or highly mutated. We applied ViFi to matched genomic and mRNA data from 68 cervical cancer samples from TCGA and found high concordance between the two. Surprisingly, viral integration resulted in a dramatic transcriptional upregulation in all proximal elements, including LINEs and LTRs that are not normally transcribed. This upregulation is highly correlated with the presence of a viral gene fused with a downstream human element. Moreover, genomic rearrangements suggest the formation of apparent circular extrachromosomal (ecDNA) human-viral structures. Our results suggest the presence of apparent small circular fusion viral/human ecDNA, which correlates with indiscriminate and unregulated expression of proximal genomic elements, potentially contributing to the pathogenesis of HPV-associated cervical cancers. ViFi is available at https://github.com/namphuon/ViFi. PMID- 29579310 TI - Transcriptional and epigenetic adaptation of maize chromosomes in Oat-Maize addition lines. AB - By putting heterologous genomic regulatory systems into contact, chromosome addition lines derived from interspecific or intergeneric crosses allow the investigation of transcriptional regulation in new genomic environments. Here, we report the transcriptional and epigenetic adaptation of stably inherited alien maize chromosomes in two oat-maize addition (OMA) lines. We found that the majority of maize genes displayed maize-specific transcription in the oat genomic environment. Nevertheless, a quarter of the expressed genes encoded by the two maize chromosomes were differentially expressed genes (DEGs). Notably, highly conserved orthologs were more severely differentially expressed in OMAs than less conserved orthologs. Additionally, syntenic genes and highly abundant genes were over-represented among DEGs. Gene suppression was more common than activation among the DEGs; however, the genes in the former maize pericentromere, which expanded to become the new centromere in OMAs, were activated. Histone modifications (H3K4me3, H3K9ac and H3K27me3) were consistent with these transcriptome results. We expect that cis regulation is responsible for unchanged expression in OMA versus maize; and trans regulation is the predominant mechanism behind DEGs. The genome interaction identified here reveals the important consequences of interspecific/intergeneric crosses and potential mechanisms of plant evolution when genomic environments interact. PMID- 29579311 TI - Strength and Cardiorespiratory Exercise Rehabilitation for Severely Burned Patients During Intensive Care Units: A Survey of Practice. AB - Minimizing the deconditioning of burn injury through early rehabilitation programs (RP) in the intensive care unit (ICU) is of importance for improving the recovery time. The aim of this study was to assess current standard of care (SOC) for early ICU exercise programs in major burn centers. We designed a survey investigating exercise RP on the ICU for burn patients with >30% total burned surface area. The survey was composed of 23 questions and submitted electronically via SurveyMonkey(r) to six major (pediatric and adult) burn centers in Texas and California. All centers responded and reported exercise as part of their RP on the ICU. The characteristics of exercises implemented were not uniform. All centers reported to perform resistive and aerobic exercises but only 83% reported isotonic and isometric exercises. Determination of intensity of exercise varied with 50% of centers using patient tolerance and 17% using vital signs. Frequency of isotonic, isometric, aerobic, and resistive exercise was reported as daily by 80%, 80%, 83%, and 50% of centers, respectively. Duration for all types of exercises was extremely variable. Mobilization was used as a form of exercise by 100% of burn centers. Our results demonstrate that although early RP seem to be integral during burn survivor's ICU stay, no SOC exists. Moreover, early RP are inconsistently administered and large variations exist in frequency, intensity, duration, and type of exercise. Thus, future prospective studies investigating the various components of exercise interventions are needed to establish a SOC and determine how and if early exercise benefits the burn survivor. PMID- 29579313 TI - Sickle cell disease in southwestern Nigeria: assessment of knowledge of primary health care workers and available facilities. AB - Background: Patients with sickle cell disease (SCD) benefit optimally from comprehensive care. In Nigeria, despite the huge burden, involvement of community health workers (CHWs) in the management of SCD is poor. Methods: This community based study assessed SCD-related knowledge of 182 CHWs from the 46 primary health care (PHC) centres in Ilesa, southwestern Nigeria. Available facilities and management practices for SCD care at these centres were also evaluated using pretested self-administered questionnaires and observational checklists. Results: The majority of CHWs (167/182 [91.8%]) knew that SCD is an inheritable blood disorder. However, only 32.4% and 26.4% knew that SCD can be diagnosed in the prenatal and neonatal periods, respectively. Also 37.4%, 49.5% and 67.6% knew about the role of chemoprophylaxis (folic acid/penicillin), adequate fluids and malaria prevention, respectively, in SCD care. Overall, 37.9% had good knowledge on the nature and care of the disease. Just 2/46 (4.3%) PHC centres treat patients with SCD. SCD-targeted nutritional counselling and referral to secondary/tertiary hospitals were poor and unorganized. No centre offered SCD screening, home visits or recordkeeping. Conclusions: The level of SCD care and knowledge of CHWs at PHC centres in southwestern Nigeria of early SCD diagnosis and crisis prevention is poor. CHWs should be regularly trained and equipped for basic SCD management, including early detection, crisis prevention, prompt referral and provision of basic genetic counselling, to dispel associated myths and stigma. PMID- 29579312 TI - TGMI: an efficient algorithm for identifying pathway regulators through evaluation of triple-gene mutual interaction. AB - Despite their important roles, the regulators for most metabolic pathways and biological processes remain elusive. Presently, the methods for identifying metabolic pathway and biological process regulators are intensively sought after. We developed a novel algorithm called triple-gene mutual interaction (TGMI) for identifying these regulators using high-throughput gene expression data. It first calculated the regulatory interactions among triple gene blocks (two pathway genes and one transcription factor (TF)), using conditional mutual information, and then identifies significantly interacted triple genes using a newly identified novel mutual interaction measure (MIM), which was substantiated to reflect strengths of regulatory interactions within each triple gene block. The TGMI calculated the MIM for each triple gene block and then examined its statistical significance using bootstrap. Finally, the frequencies of all TFs present in all significantly interacted triple gene blocks were calculated and ranked. We showed that the TFs with higher frequencies were usually genuine pathway regulators upon evaluating multiple pathways in plants, animals and yeast. Comparison of TGMI with several other algorithms demonstrated its higher accuracy. Therefore, TGMI will be a valuable tool that can help biologists to identify regulators of metabolic pathways and biological processes from the exploded high-throughput gene expression data in public repositories. PMID- 29579314 TI - Persistent, Consistent, and Extensive: The Trend of Increasing Pain Prevalence in Older Americans. AB - Objectives: Assess trends in pain prevalence from 1992 to 2014 among older U.S. adults and by major population subgroups, and test whether the trends can be explained by changes in population composition. Methods: Health and Retirement Study data include information on any pain, pain intensity, and limitations in usual activities due to pain. Average annual percent change in prevalence is calculated for any and for 2 levels of pain-mild/moderate and nonlimiting and severe and/or limiting-across demographic and socioeconomic characteristics, and for those with and without specific chronic conditions. Generalized linear latent and mixed models examine trends adjusting for covariates. Results : Linear and extensive increases in pain prevalence occurred across the total population and subgroups. The average annual percent increase was in the 2%-3% range depending upon age and sex. Increases were consistent across subgroups, persistent over time, and not due to changes in population composition. Without increases in educational attainment over time, pain prevalence increases would be even higher. Discussion: The increases in pain prevalence among older Americans are alarming and potentially of epidemic proportions. Population-health research must monitor and understand these worrisome trends. PMID- 29579316 TI - Obstacles to improving outcomes in the treatment of uveal melanoma. AB - The rate of advances in uveal melanoma has not kept pace with the rate of advances in cutaneous melanoma. Many patients lack access to or knowledge of specialty centers, and integrated multidisciplinary care between ophthalmology, radiation oncology, and medical oncology is far from the norm. This treatment isolation leads to limited communication about novel clinical trial opportunities. Clinical trials themselves are not widely available, and a lack of robust funding limits rapid and complete investigations. This review outlines the obstacles to success in uveal melanoma management and highlights strategies for overcoming these challenges. Cancer 2018;124:2693-2703. (c) 2018 American Cancer Society. PMID- 29579315 TI - Co-expression of MU and delta opioid receptors by mouse colonic nociceptors. AB - BACKGROUND AND PURPOSE: To better understand opioid signalling in visceral nociceptors, we examined the expression and selective activation of MU and delta opioid receptors by dorsal root ganglia (DRG) neurons innervating the mouse colon. EXPERIMENTAL APPROACH: DRG neurons projecting to the colon were identified by retrograde tracing. delta receptor-GFP reporter mice, in situ hybridization, single-cell RT-PCR and MU receptor-specific antibodies were used to characterize expression of MU and delta receptors. Voltage-gated Ca2+ currents and neuronal excitability were recorded in small diameter nociceptive neurons (capacitance <30 pF) by patch clamp and ex vivo single-unit afferent recordings were obtained from the colon. KEY RESULTS: In situ hybridization of oprm1 expression in Fast Blue labelled DRG neurons was observed in 61% of neurons. MU and delta receptors were expressed by 36-46% of colon DRG neurons, and co-expressed by ~25% of neurons. MU and delta receptor agonists inhibited Ca2+ currents in DRG, effects blocked by opioid antagonists. One or both agonists inhibited action potential firing by colonic afferent endings. Incubation of neurons with supernatants from inflamed colon segments inhibited Ca2+ currents and neuronal excitability. Antagonists of MU, but not delta receptors, inhibited the effects of these supernatant on Ca2+ currents, whereas both antagonists inhibited their actions on neuronal excitability. CONCLUSIONS AND IMPLICATIONS: A significant number of small diameter colonic nociceptors co-express MU and delta receptors and are inhibited by agonists and endogenous opioids in inflamed tissues. Thus, opioids that act at MU or delta receptors, or their heterodimers may be effective in treating visceral pain. PMID- 29579317 TI - Capture of tobacco use among population-based registries: Findings from 10 National Program of Cancer Registries states. AB - BACKGROUND: Tobacco use data are important when the epidemiology and prognosis of tobacco-associated cancers are being defined. Central cancer registries in 10 National Program of Cancer Registries states pilot-tested the collection of standardized tobacco use variables. This study evaluated the capture of tobacco use data and examined smoking prevalence among cancer patients. METHODS: Participating registries collected data about the use of tobacco-cigarettes, other smoked tobacco, and smokeless tobacco-for cases diagnosed during 2011-2013. The percentage of cases with known tobacco variable values was calculated, and the prevalence of tobacco use was analyzed by the primary cancer site and state. RESULTS: Among 1,646,505 incident cancer cases, 51% had known cigarette use data: 18% were current users, 31% were former users, and 51% reported never using. The percentage of cases with a known status for both other smoked tobacco and smokeless tobacco was 43%, with 97% and 98% coded as never users, respectively. The percent known for cigarette use ranged from 27% to 81% by state and improved from 47% in 2011 to 59% in 2013 for all 10 states combined. The percent known for cigarette use and the prevalence of ever smoking cigarettes were highest for laryngeal cancer and tracheal, lung, and bronchus cancer. CONCLUSIONS: Cancer registrars ascertained cigarette use for slightly more than half of all new cancer cases, but other tobacco-related fields were less complete. Studies to evaluate the validity of specific tobacco-related variables and the ability of cancer registries to capture this information from the medical record are needed to gauge the usefulness of collecting these variables through cancer surveillance systems.

PMID- 29579318 TI - Increased resource use in men with metastatic prostate cancer does not result in improved survival or quality of care at the end of life. AB - BACKGROUND: Cancer care and end-of-life (EOL) care contribute substantially to health care expenditures. Outside of clinical trials, to our knowledge there exists no standardized protocol to monitor disease progression in men with metastatic prostate cancer (mPCa). The objective of the current study was to evaluate the factors and outcomes associated with increased imaging and serum prostate-specific antigen use in men with mPCa. METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data from 2004 to 2012, the authors identified men diagnosed with mPCa with at least 6 months of follow-up. Extreme users were classified as those who had either received prostate-specific antigen testing greater than once per month, or who underwent cross-sectional imaging or bone scan more frequently than every 2 months over a 6-month period. Associations between extreme use and survival outcomes, costs, and quality of care at EOL, as measured by timing of hospice referral, frequency of emergency department visits, length of stay, and intensive care unit or hospital admissions, were examined. RESULTS: Overall, a total of 3026 men with mPCa were identified, 791 of whom (26%) were defined as extreme users. Extreme users were more commonly young, white/non-Hispanic, married, higher earning, and more educated (P<.001, respectively). Extreme use was not associated with improved quality of care at EOL. Yearly health care costs after diagnosis were 36.4% higher among extreme users (95% confidence interval, 27.4%-45.3%; P<.001). CONCLUSIONS: Increased monitoring among men with mPCa significantly increases health care costs, without a definitive improvement in survival nor quality of care at EOL noted. Monitoring for disease progression outside of clinical trials should be reserved for those in whom findings will change management. Cancer 2018;124:2212-9. (c) 2018 American Cancer Society. PMID- 29579319 TI - Biomarkers in colorectal liver metastases. AB - BACKGROUND: Despite a 5-year overall survival rate of 58 per cent after liver resection for colorectal liver metastases (CLMs), more than half of patients develop recurrence, highlighting the need for accurate risk stratification and prognostication. Traditional prognostic factors have been superseded by newer outcome predictors, including those defined by the molecular origin of the primary tumour. METHODS: This review synthesized findings in the literature using the PubMed database of articles in the English language published between 1998 and 2017 on prognostic and predictive biomarkers in patients undergoing resection of CLMs. RESULTS: Responses to preoperative chemotherapy define prognosis in patients undergoing CLM resection. There are differences by embryological origin too. Somatic mutations in the proto-oncogenes KRAS and NRAS are associated with positive surgical margins and tumour regrowth after ablation. Other mutations (such as BRAF) and co-occurring mutations in RAS/TP53 and APC/PIK3CA have emerged as important biomarkers that determine an individual patient's tumour biology and may be used to predict outcome after CLM resection. CONCLUSION: Knowledge of somatic mutations can guide the use of preoperative therapy, extent of surgical margin and selection for ablation alone. PMID- 29579320 TI - Randomized clinical trial of platysma muscle suture versus no suture for wound closure after thyroid surgery. AB - BACKGROUND: Suturing the platysma muscle during wound closure after thyroid surgery is frequently described in the literature. There is no prospective evidence to support its use or benefit. The aim of this study was to evaluate how a platysma muscle suture influences initial postoperative pain following thyroid surgery. METHODS: Patients were assigned randomly to receive a platysma suture or no platysma suture in this prospective, patient-blinded trial. The duration of follow-up was 6 months. The primary endpoint was wound-specific pain 24 h after thyroid resection. Secondary endpoints were intraoperative and perioperative analgesia requirement, postoperative pain and complications until postoperative day 14, and Patient and Observer Scar Assessment Score (POSAS) 6 months after surgery. RESULTS: Forty-one patients were randomized to each group. Visual analogue scale scores for wound-specific pain were lower in patients without a platysma suture 24 h after surgery (mean(s.d.) 3.15(1.46) versus 2.17(1.41) in groups with and without suture respectively; P = 0.002). There were no differences in the perioperative and postoperative need for analgesics, postoperative wound complications or cervical scar cosmesis 6 months after surgery (mean(s.d.) POSAS 23.99(9.53) versus 26.51(8.69); P = 0.148). CONCLUSION: Omitting the platysma muscle suture after thyroid surgery resulted in less wound specific pain initially, with no difference in postoperative wound complications or cosmetic results.

PMID- 29579321 TI - Long-term outcome of relapsed acute promyelocytic leukemia treated with oral arsenic trioxide-based reinduction and maintenance regimens: A 15-year prospective study. AB - BACKGROUND: For patients who have acute promyelocytic leukemia (APL) in second complete remission (CR2), optimal postremission strategies remain undefined. METHODS: The role of an oral arsenic trioxide (As2 O3 )-based regimen in the management of patients who had APL in CR2 was examined. RESULTS: Seventy-three patients with APL in first relapse (R1) were studied. Oral As2 O3 -based reinduction resulted uniformly in CR2, irrespective of previous As2 O3 exposure. All patients received oral As2 O3 -based maintenance in CR2. At a median follow up of 94 months (range, 9-205 months), 43 patients (58.9%) were still in CR2, and 49 (67.1%) had finished the planned 2-year CR2 maintenance with all-trans retinoic acid, oral As2 O3 , and ascorbic acid. Reinduction and maintenance treatments were well tolerated. Grade 1 and 2 headache occurred in 20 patients (27.4%). Hepatotoxicity, all in the form of transaminitis, occurred in 35 patients (47.9%; grade 1 and 2, n = 26; grade 3 and 4, n = 9). Three patients had self-limiting QTc prolongation. The 10-year leukemia-free survival rate was 56.8%. Thirty patients developed R2. Oral As2 O3 -based reinduction led to CR3 in 27 patients (90%). Post-CR3 strategies included autologous hematopoietic stem cell transplantation and oral As2 O3 maintenance. At a post-CR3 follow-up of 30 months (range, 3-166 months), 11 patients were still in CR3. The 5-year and 10 year overall survival rates in the R1 cohort were 79.5% and 67.3%, respectively. Prior receipt of oral As2 O3 maintenance in CR1 was the only risk factor for inferior leukemia-free survival. Central nervous system involvement occurred in 15 patients, including 5 who remained alive. Relapse during oral As2 O3 therapy was the only significant risk factor for central nervous system involvement. CONCLUSIONS: For patients with relapsed APL, As2 O3 remained effective despite repeated As2 O3 exposures. Oral As2 O3 maintenance was an effective postremission strategy for CR2.

AB - BACKGROUND: The peritoneal cancer index (PCI) is a comparative prognostic factor for colorectal peritoneal metastasis (CRPM). The ability of laparoscopy to determine the PCI in consideration of cytoreductive surgery remains undetermined, and this study was designed to compare it with laparotomy. METHODS: A prospective multicentre study was conducted for patients with no known CRPM, but at risk of peritoneal disease. Surgery began with laparoscopic exploration followed by open exploration to determine the PCI. Concordance between laparoscopic and open assessment was evaluated for the diagnosis of CRPM and for the PCI. RESULTS: Among 50 patients evaluated, CRPM recurrence was found in 29 (58 per cent) and 34 (68 per cent) at laparoscopic and open surgery respectively. Laparoscopy was feasible in 88 per cent (44 of 50) and deemed satisfactory by the surgeon in 52 per cent (26 of 50). Among the 25 evaluable patients with satisfactory laparoscopy, there was concordance of 96 per cent (24 of 25 patients) and 38 per cent (10 of 25) for laparoscopic and open assessment of CRPM and the PCI respectively. Where there were discrepancies, it was laparoscopy that underestimated the PCI. CONCLUSION: Laparoscopy may underestimate the extent of CRPM. PMID- 29579323 TI - Identification of potent and selective small molecule inhibitors of the cation channel TRPM4. AB - BACKGROUND AND PURPOSE: TRPM4 is a calcium-activated non-selective cation channel expressed in many tissues and implicated in several diseases, and has not yet been validated as a therapeutic target due to the lack of potent and selective inhibitors. We sought to discover a novel series of small-molecule inhibitors by combining in silico methods and cell-based screening assay, with sub-micromolar potency and improved selectivity from previously reported TRPM4 inhibitors. EXPERIMENTAL APPROACH: Here, we developed a high throughput screening compatible assay to record TRPM4-mediated Na+ influx in cells using a Na+ -sensitive dye and used this assay to screen a small set of compounds selected by ligand-based virtual screening using previously known weakly active and non-selective TRPM4 inhibitors as seed molecules. Conventional electrophysiological methods were used to validate the potency and selectivity of the hit compounds in HEK293 cells overexpressing TRPM4 and in endogenously expressing prostate cancer cell line LNCaP. Chemical chaperone property of compound 5 was studied using Western blots and electrophysiology experiments. KEY RESULTS: A series of halogenated anthranilic amides were identified with TRPM4 inhibitory properties with sub micromolar potency and adequate selectivity. We also showed for the first time that a naturally occurring variant of TRPM4, which displays loss-of-expression and function, is rescued by the most promising compound 5 identified in this study. CONCLUSIONS AND IMPLICATIONS: The discovery of compound 5, a potent and selective inhibitor of TRPM4 with an additional chemical chaperone feature, revealed new opportunities for studying the role of TRPM4 in human diseases and developing clinical drug candidates. PMID- 29579324 TI - Salvage treatment using carbon ion radiation in patients with locoregionally recurrent nasopharyngeal carcinoma: Initial results. AB - BACKGROUND: Reirradiation for locoregionally recurrent nasopharyngeal carcinoma (NPC) after a definitive dose of radiotherapy (RT) is challenging and usually associated with severe toxicities. Intensity-modulated carbon ion RT (IMCT) offers physical/biologic advantages over photon-based intensity-modulated RT. Herein, the authors report their initial experience of IMCT in previously irradiated patients with locoregionally recurrent NPC. METHODS: Patients with locoregionally recurrent, poorly differentiated or undifferentiated NPC who underwent salvage therapy with IMCT at the Shanghai Proton and Heavy Ion Center between May 2015 and August 2017 were included in the current study. The IMCT doses were 50 to 66 Gray equivalent (GyE) (2.0-3.0 GyE/daily fraction), delivered via raster scanning technology. The 1-year overall survival, disease-specific survival, progression-free survival (PFS), local recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival were calculated. Univariate and multivariate analyses of PFS were performed to identify possible predictive factors. RESULTS: Among the 75 patients included, 4 patients, 14 patients, 29 patients, and 28 patients, respectively, had recurrent American Joint Committee on Cancer stage I, stage II, stage III, and stage IVA/B disease. With a median follow-up of 15.4 months (range, 2.6-29.7 months), the 1 year overall survival, disease-specific survival, PFS, local recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival rates were 98.1%, 98.1%, 82.2%, 86.6%, 97.9%, and 96.2%, respectively. A higher fraction size of 3 GyE (vs <3 GyE) or a higher biological equivalent dose significantly improved the PFS rate on univariate analysis, but not on multivariate analysis. No patient developed acute toxicity of grade >=2 during IMCT. Late treatment-induced severe (grade 3 or 4) toxicities were infrequent, but included mucosal necrosis (9.3%), xerostomia (1.3%), and temporal lobe necrosis (1.3%). CONCLUSIONS: This initial experience in the first 75 patients with locoregionally recurrent NPC was encouraging. Carbon ion RT could provide promising survival rates with infrequent severe toxicities for patients with locoregionally recurrent NPC. Cancer 2018;124:2427-37. (c) 2018 The Authors.

PMID- 29579326 TI - Follow-up after endovascular aortic aneurysm repair can be stratified based on first postoperative imaging. AB - BACKGROUND: Lifelong postoperative surveillance is recommended following endovascular aneurysm repair (EVAR). Although the purpose is to prevent and/or identify complications early, it also results in increased cost and workload. This study was designed to examine whether it may be possible to identify patients at low risk of complications based on their first postoperative CT angiogram (CTA). METHODS: All patients undergoing EVAR in two Swedish centres between 2001 and 2012 were identified retrospectively and categorized based on the first postoperative CTA as at low risk (proximal and distal sealing zone at least 10 mm and no endoleak) or high risk (sealing zone less than 10 mm and/or presence of any endoleak) of complications. RESULTS: Some 326 patients (273 men) with a CTA performed less than 1 year after EVAR were included (low risk 212, 65.0 per cent; high risk 114, 35.0 per cent). There was no difference between the groups in terms of sex, age, co-morbidities, abdominal aortic aneurysm (AAA) diameter, preoperative AAA neck anatomy, stent-graft type or duration of follow up (mean(s.d.) 4.8(3.2) years). Five-year freedom from AAA-related adverse events was 97.1 and 47.7 per cent in the low- and high-risk groups respectively (P < 0.001). The corresponding freedom from AAA-related reintervention was 96.2 and 54.1 per cent (P < 0.001). The method had a sensitivity of 88.3 per cent, specificity of 77.0 per cent and negative predictive value of 96.6 per cent to detect AAA-related adverse events. The number of surveillance imaging per AAA related adverse event was 168 versus 11 for the low-risk versus high-risk group. CONCLUSION: Two-thirds of patients undergoing EVAR have an adequate seal and no endoleak on the first postoperative CTA, and a very low risk of AAA-related events up to 5 years. Less vigilant follow-up after EVAR may be considered for these patients. PMID- 29579325 TI - A phase 2 study of the PARP inhibitor veliparib plus temozolomide in patients with heavily pretreated metastatic colorectal cancer. AB - BACKGROUND: Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors such as veliparib are potent sensitizing agents and have been safely combined with DNA damaging agents such as temozolomide. The sensitizing effects of PARP inhibitors are magnified when cells harbor DNA repair defects. METHODS: A single-arm, open label, phase 2 study was performed to investigate the disease control rate (DCR) after 2 cycles of veliparib plus temozolomide in patients with metastatic colorectal cancer (mCRC) refractory to all standard therapies. Fifty patients received temozolomide (150 mg/m2 /d) on days 1 to 5 and veliparib (40 mg twice daily) on days 1 to 7 of each 28-day cycle. Another 5 patients with mismatch repair-deficient (dMMR) tumors were also enrolled. Twenty additional patients were then treated with temozolomide at 200 mg/m2 /d. Archived tumor specimens were used for immunohistochemistry to assess mismatch repair, phosphatase and tensin homolog deleted on chromosome 10 (PTEN), and O(6)-methylguanine-DNA methyltransferase (MGMT) protein expression levels. RESULTS: The combination was well tolerated, although some patients required dose reductions for myelosuppression. The primary endpoint was successfully met with a DCR of 24% and 2 confirmed partial responses. The median progression-free survival was 1.8 months, and the median overall survival was 6.6 months. PTEN protein expression and MGMT protein expression were not predictors of DCR. There was also a suggestion of worse outcomes for patients with dMMR tumors. CONCLUSIONS: In this heavily pretreated mCRC population, a combination of veliparib and temozolomide was well tolerated with temozolomide doses up to 200 mg/m2 /d, and it was clinically active. PARP inhibitor-based therapy merits further exploration in patients with mCRC. Cancer 2018;124:2337-46. (c) 2018 American Cancer Society. PMID- 29579327 TI - Serum carcinoembryonic antigen trends for diagnosing colorectal cancer recurrence in the FACS randomized clinical trial. AB - BACKGROUND: Most guidelines recommend that patients who have undergone curative resection for primary colorectal cancer are followed up for 5 years with regular blood carcinoembryonic antigen (CEA) tests to trigger further investigation for recurrence. However, CEA may miss recurrences, or patients may have false alarms and undergo unnecessary investigation. METHODS: The diagnostic accuracy of trends in CEA measurements for recurrent colorectal cancer, taken as part of the FACS (Follow-up After Colorectal Surgery) trial (2003-2014), were analysed. Investigation to detect recurrence was triggered by clinical symptoms, scheduled CT or colonoscopy, or a CEA level of at least 7 MUg/l above baseline. Time dependent receiver operating characteristic (ROC) curve analysis was used to compare the diagnostic accuracy of CEA trends with single measurements. CEA trends were estimated using linear regression. RESULTS: The area under the ROC curve (AUC) for CEA trend was at least 0.820 across all 5 years of follow-up. In comparison, the AUCs for single measurements ranged from 0.623 to 0.749. Improvement was most marked at the end of the first year of follow-up, with the AUC increasing from 0.623 (95 per cent c.i. 0.509 to 0.736) to 0.880 (0.814 to 0.947). However, no individual trend threshold achieved a sensitivity above 70 per cent (30 per cent missed recurrences). CONCLUSION: Interpreting trends in CEA measurements instead of single CEA test results improves diagnostic accuracy for recurrence, but not sufficiently to warrant it being used as a single surveillance strategy to trigger further investigation. In the absence of a more accurate biomarker, monitoring trends in CEA should be combined with clinical, endoscopic and imaging surveillance for improved accuracy. PMID- 29579329 TI - Prediction of morbidity following cytoreductive surgery for metastatic gastrointestinal stromal tumour in patients on tyrosine kinase inhibitor therapy. AB - BACKGROUND: Although cytoreductive surgery has been shown to be beneficial in carefully selected patients with metastatic gastrointestinal stromal tumours (GISTs) treated with tyrosine kinase inhibitors (TKIs), factors predictive of postoperative morbidity have not been investigated previously. METHODS: A surgical complexity score for GIST metastasectomy (GM-SCS) composed of patient related and surgical factors was assigned retrospectively to patients with metastatic GIST treated with TKI therapy and surgery at two institutions between 2002 and 2014. The ability of clinicopathological factors and GM-SCS to predict postoperative morbidity was assessed by means of a multivariable logistic regression model. Postoperative complications were categorized using the Clavien Dindo classification. RESULTS: Some 400 operations on 323 patients with metastatic GIST on TKIs were included. Complications were observed following 110 operations (27.5 per cent) including 70 major complications (grade III-V) (17.5 per cent of 400 operations). Patients were divided into low (5 points or less; 100 patients, 25.0 per cent), intermediate (6-9 points; 191, 47.8 per cent) and high (at least 10 points; 109, 27.3 per cent) complexity scoring groups based on the GM-SCS. An intermediate (odds ratio (OR) 2.88; P = 0.008) and high (OR 5.40; P < 0.001) GM-SCS were independent predictors of overall complications, whereas only a high GM-SCS was independently predictive of a major complication (OR 3.65; P = 0.018). Metastatic mitotic index was also an independent predictor of overall complications (OR 2.55; P = 0.047). GM-SCS did not predict progression-free or overall survival. CONCLUSION: A gastrointestinal stromal tumour metastastectomy surgical complexity score can predict morbidity, which may help in preoperative risk stratification and optimal treatment planning. PMID- 29579328 TI - Complex karyotype in patients with mantle cell lymphoma predicts inferior survival and poor response to intensive induction therapy. AB - BACKGROUND: Risk stratification of newly diagnosed patients with mantle cell lymphoma (MCL) primarily is based on the MCL International Prognostic Index (MIPI) and Ki-67 proliferative index. Single-center studies have reported inferior outcomes in patients with a complex karyotype (CK), but this remains an area of controversy. METHODS: The authors retrospectively reviewed 483 patients from 5 academic centers in the United States and described the effect of a CK on survival outcomes in individuals with MCL. RESULTS: A CK was found to be associated with inferior overall survival (OS) (4.5 vs 11.6 years; P<.01) and progression-free survival (PFS) (1.9 vs 4.4 years; P<.01). In patients who underwent high-intensity induction followed by autologous stem cell transplantation (ASCT) in first remission, a CK was associated with poor OS (5.1 vs 11.6 years; P = .04) and PFS (3.6 vs 7.8 years; P<.01). Among patients with a CK, high-intensity induction had no effect on OS (4.5 vs 3.8 years; P = .77) nor PFS (2.3 vs 1.5 years; P = .46). Similarly, ASCT in first remission did not improve PFS (3.5 vs 1.2 years; P = .12) nor OS (5.1 vs 4.0 years; P = .27). On multivariable analyses with Ki-67 and MIPI, only CK was found to be predictive of OS (hazard ratio [HR], 1.98; 95% confidence interval [95% CI], 1.12-3.49 [P = .02]), whereas both CK (HR, 1.91; 95% CI, 1.17-3.12 [P = .01]) and Ki-67 >30% (HR, 1.86; 95% CI, 1.06-3.28 [P = .03]) were associated with inferior PFS. Multivariable analysis did not identify any specific cytogenetic abnormalities associated with inferior survival. CONCLUSIONS: CK appears to be independently associated with inferior outcomes in patients with MCL regardless of the intensity of induction therapy and receipt of ASCT. Cytogenetics should be incorporated into the workup of a new diagnosis of MCL and novel therapeutic approaches should be investigated for patients with CK. Cancer 2018;124:2306-15.

AB - BACKGROUND: Posttransplant lymphoproliferative disorder (PTLD) is a life threatening complication of solid organ transplantation. Histologic heterogeneity and a lack of treatment standards have made evaluating clinical outcomes in specific patient populations difficult. This systematic literature review investigated the impact of the PTLD histologic subtype on survival in a large data set. METHODS: Case series were identified on PubMed with the search terms post-transplant lymphoproliferative disorder/disease, PTLD, and solid organ transplantation, with additional publications identified through reference lists. The patient characteristics, immunosuppressive regimen, treatment, survival, and follow-up time for 306 cases were extracted from 94 articles, and these cases were combined with 11 cases from Emory University Hospital. Patients with a recorded subtype were included in a Kaplan-Meier survival analysis (n = 234). Cox proportional hazards regression analyses identified predictors of overall survival (OS) for each subtype and B-cell subgroup. RESULTS: OS differed significantly between monomorphic T-cell neoplasms (median, 9 months) and polymorphic, monomorphic B-cell, and Hodgkin-type neoplasms, for which the median OS was not reached (P = .0001). Significant differences in OS among B subgroups were not detected, but there was a trend toward decreased survival for patients with Burkitt-type PTLD. Kidney transplantation and a reduction of immunosuppression were associated with increased OS for patients with B-cell neoplasms in a multivariate analysis. Immunosuppression with azathioprine was associated with decreased OS for patients with T-cell neoplasms, whereas radiotherapy was associated with improved OS for patients with that subtype. CONCLUSIONS: The histologic subtype represents an important prognostic factor in PTLD, with patients with T-cell neoplasms exhibiting very poor OS. Possibly lower survival for certain subsets of patients with B-cell PTLD should be explored further and suggests the need for subtype-specific therapies to improve outcomes. Cancer 2018;124:2327-36.

AB - BACKGROUND: Cutaneous squamous cell carcinoma (CSCC) is a very common malignancy in which most patients present with localized disease. Recurrent and metastatic disease is rare, and there is no standard therapy. These tumors frequently overexpress the epidermal growth factor receptor (EGFR). We conducted a phase 2 trial to determine the response rate to therapy with erlotinib, an EGFR tyrosine kinase inhibitor, in patients with locoregionally recurrent or metastatic CSCC that was not amenable to curative treatment (NCT01198028). METHODS: Eligible patients had CSCC not amenable to curative intent therapy. Patients who had previously received anti-EGFR targeted therapy were excluded. All patients received oral therapy with erlotinib 150 mg daily. Response was assessed every 8 weeks, and treatment continued until progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint was overall response rate according to RECIST 1.1 criteria. RESULTS: A total of 39 patients received treatment during the trial; 29 of these patients were evaluable for response. The overall response rate was 10% (3/29); all responses were partial responses. The disease control rate (partial response + stable disease) was 72% (21/29). The median progression free survival was 4.7 months (95% confidence interval, 3.5-6.2 months); the median overall survival was 13 months (95% confidence interval, 8.4-20.5 months). No unexpected toxicities were seen. CONCLUSION: Erlotinib therapy was feasible for most patients with incurable CSCC and was associated with expected toxicities. However, only a modest response rate of 10% was observed. Further study of EGFR tyrosine kinase inhibitors in this patient population is not warranted. Cancer 2018;124:2169-73.

PMID- 29579332 TI - Late therapeutic intervention with a respiratory syncytial virus L-protein polymerase inhibitor, PC786, on respiratory syncytial virus infection in human airway epithelium. AB - BACKGROUND AND PURPOSE: Effective anti-respiratory syncytial virus (RSV) agents are still not available for clinical use. Current major targets are virus surface proteins, such as a fusion protein involved in viral entry, but agents effective after RSV infection is established are required. Here we have investigated the effects of late therapeutic intervention with a novel inhaled RSV polymerase inhibitor, PC786, on RSV infection in human airway epithelium. EXPERIMENTAL APPROACH: Air liquid interface-cultured bronchial or small airway epithelium was infected with RSVA2. PC786 was applied apically or basolaterally once daily following peak virus load on Day 3 post inoculation. Apical wash was collected daily for determination of viral burden by PCR and plaque assay (primary endpoints) and biomarker analyses. The effects were compared with those of ALS 8112, an anti-RSV nucleoside analogue, and GS-5806, a fusion-protein inhibitor, which were treated basolaterally. KEY RESULTS: Late intervention with GS-5806 did not show significant anti-viral effects, but PC786 produced potent, concentration dependent inhibition of viral replication with viral load falling below detectable limits 3 days after treatment commenced in airway epithelium. These effects were superior to those of ALS-8112. PC786 showed inhibitory activities against RSV-induced increases of CCL5, IL-6, double-strand DNA and mucin. The effects of PC786 were also confirmed in small airway epithelium. CONCLUSION AND IMPLICATIONS: Late therapeutic intervention with the RSV polymerase inhibitor, PC786, reduced the viral burden quickly in human airway epithelium. Thus, PC786 demonstrates the potential to be an effective therapeutic agent to treat active RSV infection. PMID- 29579333 TI - Initial experience with purely laparoscopic living-donor right hepatectomy. AB - BACKGROUND: There may be concerns about purely laparoscopic donor right hepatectomy (PLDRH) compared with open donor right hepatectomy, especially when performed by surgeons accustomed to open surgery. This study aimed to describe technical tips and pitfalls in PLDRH. METHODS: Data from donors who underwent PLDRH at Seoul National University Hospital between December 2015 and July 2017 were analysed retrospectively. Endpoints analysed included intraoperative events and postoperative complications. All operations were performed by a single surgeon with considerable experience in open living donor hepatectomy. RESULTS: A total of 26 donors underwent purely laparoscopic right hepatectomy in the study interval. No donor required transfusion during surgery, whereas two underwent reoperation. In two donors, the dissection plane at the right upper deep portion of the midplane was not correct. One donor experienced portal vein injury during caudate lobe transection, and one developed remnant left hepatic duct stenosis. One donor experienced remnant portal vein angulation owing to a different approach angle, and one experienced arterial damage associated with the use of a laparoscopic energy device. One donor had postoperative bleeding due to masking of potential bleeding foci owing to intra-abdominal pressure during laparoscopy. Two donors experienced right liver surface damage caused by a xiphoid trocar. CONCLUSION: Purely laparoscopic donor hepatectomy differs from open donor hepatectomy in terms of angle and caudal view. Therefore, surgeons experienced in open donor hepatectomy must gain adequate experience in laparoscopic liver surgery and make adjustments when performing PLDRH. PMID- 29579334 TI - Long-term safety and survival with gefitinib in select patients with advanced non small cell lung cancer: Results from the US IRESSA Clinical Access Program (ICAP). AB - BACKGROUND: This is the first report of long-term (>10 years) safety, tolerability, and survival data on patients with non-small cell lung cancer (NSCLC) who received treatment with gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. METHODS: Patients with advanced NSCLC (N = 191) who entered the IRESSA Clinical Access Program (ICAP) (June 2011 to January 2013) and had previously obtained a clinical benefit from gefitinib therapy (including patients who had received gefitinib since 2001) were analyzed for adverse events (AEs). A subset of patients (n = 79) underwent retrospective chart review to capture demographic, safety, and survival data. RESULTS: Seventy five of 191 patients (39%) remained on long-term gefitinib therapy as of September 2016. Overall, serious AEs (SAEs) were reported in 64 patients (34%), the majority of which were attributed to underlying disease or comorbidities; only 3 patients (1.6%) had SAEs that were considered as possibly gefitinib related. In the retrospective chart review cohort, 70% of patients were women; 58% were former smokers, and 30% were never-smokers; 56% were diagnosed with adenocarcinoma, and 13% were diagnosed with squamous carcinoma. Although EGFR mutational status was tested in only 17 patients (22%), it was assumed that most tumors were EGFR-mutation-positive. The median duration of gefitinib therapy was 11.1 years (7.8 years before and 3.5 years during ICAP), with 10-year and 15-year survival rates of 86% and 59%, respectively, from the initiation of therapy. CONCLUSIONS: A subset of long-term NSCLC survivors who were receiving gefitinib had an excellent long-term safety profile. Although it is assumed that most of these patients' tumors harbor EGFR mutations, molecular studies of available tumor specimens are planned to uncover the features that predict long-term survival.

AB - BACKGROUND: Recent cancer survival trends among American Indian and Alaska Native (AN) people are not well understood; survival has not been reported among AN people since 2001. METHODS: This study examined cause-specific survival among AN cancer patients for lung, colorectal, female breast, prostate, and kidney cancers. It evaluated whether survival differed between cancers diagnosed in 1992 2002 (the earlier period) and cancers diagnosed in 2003-2013 (the later period) and by the age at diagnosis (<65 vs >=65 years), stage at diagnosis (local or regional/distant/unknown), and sex. Kaplan-Meier and Cox proportional hazards models were used to estimate univariate and multivariate-adjusted cause-specific survival for each cancer. RESULTS: An improvement was observed in 5-year survival over time from lung cancer (hazard ratio [HR] for the later period vs the earlier period, 0.83; 95% confidence interval [CI], 0.72-0.97), and a marginally nonsignificant improvement was observed for colorectal cancer (HR, 0.81; 95% CI, 0.66-1.01). Site-specific differences in survival were observed by age and stage at diagnosis. CONCLUSIONS: This study presents the first data on cancer survival among AN people in almost 2 decades. During this time, AN people have experienced improvements in survival from lung and colorectal cancers. The reasons for these improvements may include increased access to care (including screening) as well as improvements in treatment. Improving cancer survival should be a priority for reducing the burden of cancer among AN people and eliminating cancer disparities. Cancer 2018;124:2570-7. (c) 2018 American Cancer Society. PMID- 29579337 TI - Power and sample size calculation incorporating misspecifications of the variance function in comparative clinical trials with over-dispersed count data. AB - Over-dispersed count data are frequently observed in clinical trials where the primary endpoint is occurrence of clinical events. Sample sizes of comparative clinical trials with these data are typically calculated under negative binomial models or quasi-Poisson models with specified variance functions, or under the assumption that the specified "working" variance functions are correctly specified. In this article, we propose a sample size formula anticipating misspecifications of the working variance function. We derived a method based on the asymptotic distribution of a Wald test statistic with a sandwich-type robust variance estimator under quasi-Poisson models. Under misspecifications of the working variance function, the asymptotic variance of the estimator of the treatment effect is expressed as a form involving both true and working variance functions. Our sample size formula includes several existing formulas as special cases when the working variance function is correctly specified as the true variance function. We also consider a sensitivity analysis for possible misspecifications of the "true" variance function when estimating sample sizes using our formula. A simulation study demonstrated the adequacy of our formulas in finite sample size settings. An application to a clinical trial to evaluate the treatment effect on prevention of COPD exacerbation is provided. PMID- 29579336 TI - Risk profile analysis and complications after surgery for autoimmune thyroid disease. AB - BACKGROUND: Surgical approaches to autoimmune thyroid disease are currently hampered by concerns over postoperative complications. Risk profiles and incidences of postoperative complications have not been investigated systematically, and studies with sufficient power to show valid data have not been performed. METHODS: A prospective multicentre European study was conducted between July 2010 and December 2012. Questionnaires were used to collect data prospectively on patients who had surgery for autoimmune thyroid disease and the findings were compared with those of patients undergoing surgery for multinodular goitre. Logistic regression analysis was used to evaluate risk factors for thyroid surgery-specific complications, transient and permanent recurrent laryngeal nerve (RLN) palsy and hypoparathyroidism. RESULTS: Data were available for 22 011 patients, of whom 18 955 were eligible for analysis (2488 who had surgery for autoimmune thyroid disease and 16 467 for multinodular goitre). Surgery for multinodular goitre and that for autoimmune thyroid disease did not differ significantly with regard to general complications. With regard to thyroid surgery-specific complications, the rate of temporary and permanent vocal cord palsy ranged from 2.7 to 6.7 per cent (P = 0.623) and from 0.0 to 1.4 per cent (P = 0.600) respectively, whereas the range for temporary and permanent hypoparathyroidism was 12.9 to 20.0 per cent (P < 0.001) and 0.0 to 7.0 per cent (P < 0.001) respectively. In logistic regression analysis of transient and permanent vocal cord palsy, autoimmune thyroid disease was not an independent risk factor. Autoimmune thyroid disease, extent of thyroid resection, number of identified parathyroid glands and no autotransplantation were identified as independent risk factors for both transient and permanent hypoparathyroidism. CONCLUSION: Surgery for autoimmune thyroid disease is safe in comparison with surgery for multinodular goitre in terms of general complications and RLN palsy. To avoid the increased risk of postoperative hypoparathyroidism, special attention needs to be paid to the parathyroid glands. PMID- 29579338 TI - Development of CNS metastases and survival in patients with inflammatory breast cancer. AB - BACKGROUND: Inflammatory breast cancer (IBC) is associated with a poor prognosis and high risk of central nervous system (CNS) metastases. METHODS: We retrospectively reviewed stage III-IBC patients compared with noninflammatory invasive ductal carcinoma (NI-IDC) patients treated between January 1, 1984, and December 31, 2011, who began primary treatment within 1 year of diagnosis and had been followed up for at least 1 year before the development of CNS metastasis or death. Cumulative CNS metastasis incidence and post-CNS metastasis overall survival (OS) estimates were computed. Multivariable Cox proportional hazard models explored factors for post-CNS metastasis survival. RESULTS: A total of 2323 patients were identified (589-IBC/1734-NI-IDC). Eighty-one IBC patients developed CNS metastasis, versus 154 NI-IDC patients. The 2-, 5-, and 10-year cumulative CNS metastasis incidence rates in IBC and NI-IDC were 9.8%, 15.8%, 17.4% and 6.5%, 10.1%, and 12.7%, respectively. This was significantly different between IBC and NI-IDC patients (P = .0037). Multicovariate competing risk regression models in IBC and NI-IDC patients showed no statistically significant associations with the risk of developing CNS metastasis, except neoadjuvant taxane use in NI-IDC patients (hazard ratio, 0.45; 95% confidence interval, 0.24 0.83; P = .011). The median follow-up was 7.2 years, and the median post-CNS metastasis OS was not significantly different between IBC (7.6 months) and NI-IDC (5.6 months) patients. One hundred ninety patients with CNS metastasis died. HER2 positive patients had better OS, with a median 14.1 versus 4.3 months (P < .0001). Age >50 years (P = .012) but not IBC status was a significant predictor of post-CNS metastasis survival. CONCLUSION: IBC patients demonstrated higher CNS metastasis incidence rates but OS following CNS metastases is similar in both groups. HER2 status and age may play prognostic roles.

PMID- 29579339 TI - Mature results of a prospective study of deintensified chemoradiotherapy for low risk human papillomavirus-associated oropharyngeal squamous cell carcinoma. AB - BACKGROUND: The purpose of the current study was to determine quality of life and tumor control from a prospective phase 2 clinical trial evaluating deintensified chemoradiotherapy for favorable risk, human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma. METHODS: Patients with T0-T3, N0-N2c, M0, p16-positive disease and a minimal smoking history were treated with 60 grays of intensity-modulated radiotherapy with concurrent weekly intravenous cisplatin (30 mg/m2 ). The primary study endpoint was the pathologic complete response rate based on biopsy of the primary site and dissection of pretreatment positive lymph node regions. The pathologic complete response rate as previously reported was 86%. Herein, the authors report secondary endpoint measures of local control, regional control, cause-specific survival, distant metastasis-free survival, and overall survival, and patient-reported outcomes (European Organization for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [EORTC QLQ C30] and the Patient-Reported Outcomes version of Common Terminology Criteria for Adverse Events [PRO-CTCAE]). RESULTS: A total of 44 patients enrolled with a median follow-up of 36 months (88% with >=2 years). The 3-year local control, regional control, cause-specific survival, distant metastasis-free survival, and overall survival rates were 100%, 100%, 100%, 100%, and 95%, respectively. The mean before and 3-year after EORTC QOL scores were: global: 80 of 78; swallowing: 11 of 11; dry mouth: 16 of 41; and sticky saliva: 6 of 29. The mean before and 3 year after PRO-CTCAE scores were: swallowing: 0.4 of 0.7; and dry mouth: 0.4 of 1.4. Approximately 39% of patients required a feeding tube (median duration, 15 weeks; none were permanent). There were no >=grade 3 late adverse events reported. CONCLUSIONS: For patients with favorable-risk human papillomavirus associated oropharyngeal squamous cell carcinoma, a substantially decreased intensity of therapy with 60 grays of intensity-modulated radiotherapy and weekly low-dose cisplatin produced better preservation of quality of life compared with standard therapies while maintaining excellent 3-year tumor control and survival.

PMID- 29579340 TI - Association of externalizing religious and spiritual beliefs on stage of colon cancer diagnosis among black and white multicenter urban patient populations. AB - BACKGROUND: This study explores whether externalizing religious and spiritual beliefs is associated with advanced-stage colon cancer at initial oncology presentation and whether this association is stronger for blacks than for whites. METHODS: Patients who had newly diagnosed, invasive colon cancer were recruited at 9 sites in the Chicago metropolitan area. Eligible patients were non-Hispanic white or black, ages 30 to 79 years, and diagnosed with a primary invasive colon cancer. Patients were interviewed on prior screening and diagnosis. Social and attitudinal constructs were measured, including the God Locus of Health Control (GLHC) and Religious Problem Solving. The final response rate was 52% and included 407 patients. RESULTS: The median age was 59 years (range, 30-79 years), and 51% of participants were black. Cancer stage was available for 389 (96%) patients and was divided between late stage (stages III-IV; 60%) and early stage (stages I-II; 40%). Multivariate analysis indicated that patients in the highest tertile of scores on the GLHC were more likely have an advanced stage of disease at presentation (odds ratio, 2.14; 95% confidence interval, 1.00-4.59; P = .05) compared with those in the lowest tertile. No significant interaction was identified between race and GLHC scores for stage at presentation (P = .78). CONCLUSIONS: In a large sample of black and white individuals across diverse health care systems, higher scores on the GLHC predicted late disease stage at presentation. Although blacks had significantly higher GLHC scores, race was not associated with stage at presentation, nor was the association between GLHC and stage limited to blacks. Further work is needed to better understand this association and to develop interventions to better connect the religious and health care spheres. Cancer 2018;124:2578-87.

AB - We propose a general Bayesian nonparametric (BNP) approach to causal inference in the point treatment setting. The joint distribution of the observed data (outcome, treatment, and confounders) is modeled using an enriched Dirichlet process. The combination of the observed data model and causal assumptions allows us to identify any type of causal effect-differences, ratios, or quantile effects, either marginally or for subpopulations of interest. The proposed BNP model is well-suited for causal inference problems, as it does not require parametric assumptions about the distribution of confounders and naturally leads to a computationally efficient Gibbs sampling algorithm. By flexibly modeling the joint distribution, we are also able to impute (via data augmentation) values for missing covariates within the algorithm under an assumption of ignorable missingness, obviating the need to create separate imputed data sets. This approach for imputing the missing covariates has the additional advantage of guaranteeing congeniality between the imputation model and the analysis model, and because we use a BNP approach, parametric models are avoided for imputation. The performance of the method is assessed using simulation studies. The method is applied to data from a cohort study of human immunodeficiency virus/hepatitis C virus co-infected patients. PMID- 29579342 TI - Cost considerations for systemic therapy for patients with advanced genitourinary malignancies. AB - The rising cost of health care in the United States has been the focus of intense debate within the medical, legal, and legislative arenas, with the cost of cancer care representing an important component. Cost effectiveness is not always easy to define, and there is no standard metric in assessing this measure related to cancer therapies. Significant controversy surrounds exactly what is the appropriate cost per added year of life. This review examines cost, effectiveness, and comparative cost effectiveness of novel systemic therapies for patients with urologic malignancies. Cancer 2018;124:2897-905.

AB - Separations of bare superparamagnetic magnetite nanoparticles (BSPMNPs, approx. 11 nm diameter) was performed using non-complexing (nitrate) and complexing (chloride, citrate and phosphate) electrolyte ions with additions of tetramethylammonium hydroxide (TMAOH), which is commonly applied to control the synthesis of stable iron oxides. The use of TMAOH as a background electrolyte (BGE) additive for capillary electrophoresis (CE) separations provided for the first time electropherograms of BSPMNPs exhibiting symmetrical and highly reproducible peaks, free of spurious spikes characteristic of nanoparticle clusters. Consequently, accurate determination of the electrophoretic effective mobility of BSPMNPs was possible, yielding a value of -3.345E-08 m2 V-1 s-1 (relative standard deviation (RSD) of 0.500%). The obtained mobilities of BSPMNPs in the presence of various electrolyte ions show that the degree of complexation with the surface of BSPMNPs follows the order chloride < citrate < phosphate, correlating with the stabilities of Fe(III) complexes with the respective anions. Finally, bare and carboxylated iron oxide nanoparticles were successfully separated in only 10 min using 10 mM Tris-nitrate containing 20 mM of TMAOH as electrolyte. Our findings show that simple and rapid CE experiments are an excellent tool to characterise and monitor properties and interactions of iron oxide nanoparticles with other molecules for surface modification purposes.

AB - Microproteomic studies have improved our knowledge of cell biology. Yet, with mass spectrometry (MS) analysis, accuracy can be lost for protein identification and quantification when using heterogeneous samples. Laser capture microdissection (LCM) allows for the enrichment of specific subsets of cells to study their proteome; however, sample fixation is necessary. Unfortunately, fixation hampers MS results due to protein cross-linking. The aim of this study was to identify both a fixation protocol and an extraction method that returns the best yield of proteins for downstream MS analysis, while preserving cellular structures. We compared glutaraldehyde (GLU), a common fixative to preserve cells, to dithiobispropionimidate (DTBP), a cleavable cross-linker. Our DTBP fixation/extraction protocol greatly increased the protein recovery. In fact, while 1000 GLU fixed cells returned only 159 unique protein hits, from 1464 unique peptides of 1994 unique collected spectra, 1000 DTBP fixed cells resulted in 567 unique collected protein hits, from 7542 unique peptides, of 10,401 unique collected spectra. That is, a 3.57-fold increase in protein hits, 5.15-fold increase in unique peptides, and a 5.22-fold increase in unique collected spectra. Overall, the novel protocol introduced here allows for a very efficient protein recovery and good sample quality for MS after sample collection using LCM. PMID- 29579345 TI - The effects of prebiotic supplementation on weight gain, diarrhoea, constipation, fever and respiratory tract infections in the first year of life. AB - AIM: This study was conducted to evaluate the effect of prebiotics on some common clinical ailments in healthy term infants. METHODS: Sixty healthy-term, breastfed (BF) infants were included. Along with these infants, 120 healthy-term formula fed infants were randomly assigned to either the prebiotic formula (PF, n = 60) or regular formula (RF, n = 60) groups. Ready-to-use prebiotic-supplemented formula containing galacto-oligosaccharides and polydextrose (ratio 1:1) was used. RESULTS: At 2 months of age, PF infants demonstrated significantly higher weight gain than BF and RF. At 6 months of age, bodyweight was significantly higher in the RF group compared to BF and PF groups (P < 0.05). Similar results were seen at 8, 10 and 12 months of age. At 10 months of age, the duration of diarrhoea was significantly shorter in PF-fed compared to the RF (P = 0.03) group. A significant difference was found between PF and RF (P < 0.0001) and BF and RF groups (P = 0.002) for diarrhoea duration. Means of constipation episodes per year were 0.03 +/- 0.18, 0.433 +/- 0.77 and 0.1 +/- 0.30 for the BF, RF and PF groups, respectively, with significant difference found between BF and RF (P = 0.006) and PF and RF (P = 0.02). The means of episodes of respiratory tract infections per year for BF, RF and PF groups were 1 +/- 0.69, 1.6 +/- 0.88 and 1 +/- 0.58, respectively (P = 0.01). CONCLUSION: Prebiotic-supplemented and regular formula were similar to breast milk regarding prophylactic effects for diarrhoea, constipation and respiratory tract infections in the first year of life. Prebiotic-supplemented formula may be an appropriate substitution for breast milk when breast milk in unavailable. PMID- 29579347 TI - Two-fold Bioorthogonal Derivatization by Different Formylglycine-Generating Enzymes. AB - Formylglycine-generating enzymes are of increasing interest in the field of bioconjugation chemistry. They catalyze the site-specific oxidation of a cysteine residue to the aldehyde-containing amino acid Calpha -formylglycine (FGly). This non-canonical residue can be generated within any desired target protein and can subsequently be used for bioorthogonal conjugation reactions. The prototypic formylglycine-generating enzyme (FGE) and the iron-sulfur protein AtsB display slight variations in their recognition sequences. We designed specific tags in peptides and proteins that were selectively converted by the different enzymes. Combination of the different tag motifs within a single peptide or recombinant protein enabled the independent and consecutive introduction of two formylglycine residues and the generation of heterobifunctionalized protein conjugates.

AB - Crustaceans have been long used as model animals for neuromodulation studies because of their well-defined neural circuitry. The identification of small molecule metabolites and signaling molecules in circulating fluids and neuronal tissues presents unique challenges due to their diverse structures, biological functions, and wide range of concentrations. LC combined with high resolution MS/MS is one of the most powerful tools to uncover endogenous small molecules. Here we explored several sample preparation techniques (solid-phase extraction and denaturing) and MS data acquisition strategies (data-dependent acquisition and targeted MS2-based acquisition) that provided complementary coverage and improved overall identification rate in C18 LC-MS/MS experiment. By MS/MS spectral matching with mzCloud database and those generated from standard compounds, a total of 129 small molecule metabolites and neurotransmitters were identified from crustacean hemolymph and neuronal tissues. These confidently identified small molecules covered predominant biosynthetic pathways for major neurotransmitters, validating the effectiveness of the high-throughput RPLC-MS/MS approach in studying the metabolism of neurotransmitters. PMID- 29579350 TI - A simple, fast, and accurate thermodynamic-based approach for transfer and prediction of gas chromatography retention times between columns and instruments Part I: Estimation of reference column geometry and thermodynamic parameters. AB - The transfer of retention times based on thermodynamic models between columns can aid in separation optimization and compound identification in gas chromatography. Although earlier investigations have been reported, this problem remains unsuccessfully addressed. One barrier is poor predictive accuracy when moving from a reference column or system to a new target column or system. This is attributed to challenges associated with the accurate determination of the effective geometric parameters of the columns. To overcome this, we designed least squares-based models that account for geometric parameters of the columns and thermodynamic parameters of compounds as they partition between mobile and stationary phases. Quasi-Newton-based algorithms were then used to perform the numerical optimization. In this first of three parts, the model used to determine the geometric parameters of the reference column and the thermodynamic parameters of compounds subjected to separation is introduced. As will be shown, the overall approach significantly improves the predictive accuracy and transferability of thermodynamic data (and retention times) between columns of the same stationary phase chemistry. The data required for the determination of the thermodynamic parameters and retention time prediction are obtained from fast and simple experiments. The proposed model and optimization algorithms were tested and validated using simulated and experimental data. PMID- 29579351 TI - Three-dimensional microfluidic chip with twin-layer herringbone structure for high efficient tumor cell capture and release via antibody-conjugated magnetic microbeads. AB - Harvesting rare circulating tumor cells (CTCs) from human blood is distinctly substantial to monitor tumor stage and evaluate therapeutic efficacy. As a proof of-concept study, a microfluidic chip with twin-layer herringbone grooves was developed to isolate and recover tumor cells with high efficiency based on the immunoreaction between cells and antibody-conjugated microbeads (MBs) under local magnetic field. Functional MBs were initially localized onto the internal channel wall through the magnetic guidance. Then, infused tumor cells were deviated into the herringbone groove via passive microvortex and were further trapped through an irreversible interaction with MBs. Upon the removal of magnet, the captured cells and residual MBs were released from the channel and collected for further analysis in cell adhesion and proliferation in vitro. Capture efficiency of tumor cells reached up to ~90% and limit of detection was down to 50 cells per mL based on this approach. Furthermore, recovery rate of tumor cells was as high as ~94%, and potencies of cell attachment and proliferation was well maintained in retrieved cells. Hence, the present technique has a great potential for the isolation, quantitation and recovery of CTCs for cancer theranostic guidance and biomolecular analysis.

PMID- 29579353 TI - Northern Italy in the American South: Assessing interobserver reliability within the Milan System for Reporting Salivary Gland Cytopathology. AB - BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) has been proposed to standardize salivary gland fine-needle aspiration (FNA) diagnoses. This study assessed salivary gland FNA results and risk of malignancy (ROM) rates at the University of North Carolina as well as the interobserver reliability (IOR) of the atypia of undetermined significance (AUS) and salivary gland neoplasm of uncertain malignant potential (SUMP) categories. METHODS: The electronic medical record was searched for FNA cases from 2010 to 2017 with subsequent surgical resections. Histologic diagnosis was used for gold-standard comparison. The original cytologic results were then converted into MSRSGC categories (nondiagnostic, nonneoplastic, AUS, benign neoplasm, SUMP, suspicious, and malignant). For the assessment of IOR, 23 cases were selected with enrichment for cases diagnosed as AUS (n = 11) or SUMP (n = 9). Six boarded cytopathologists and 1 cytopathology fellow assessed representative slides and provided an MSRSGC diagnosis for each case. Fleiss' kappa coefficients were calculated to determine IOR. RESULTS: The ROM was 33% for both AUS and SUMP cases; however, the risk of neoplasia was 56% for AUS cases and 100% for SUMP cases. Fleiss' kappa for the AUS category was 0.217 (P < .05), and Fleiss' kappa for the SUMP category was 0.024 (P = .74). CONCLUSIONS: In this study assessing the IOR of MSRSGC categories, fair agreement and slight agreement were found for the AUS and SUMP categories, respectively. Observers preferentially used the AUS or benign neoplasm category for SUMP cases, perhaps because of unfamiliarity with SUMP as a diagnostic option. The initial adoption of a new reporting system will require a quality assessment to ensure that the system is reliable and useful for clinicians. Cancer Cytopathol 2018;126:390-6.

AB - AIM: Penetrating head injuries (pHIs) are associated with high morbidity and mortality. Data on pHIs in children outside North America are limited. We describe the mechanism of injuries, neuroimaging findings, neurosurgery and mortality for pHIs in Australia and New Zealand. METHODS: This was a planned secondary analysis of a prospective observational study of children <18 years who presented with a head injury of any severity at any of 10 predominantly paediatric Australian/New Zealand emergency departments (EDs) between 2011 and 2014. We reviewed all cases where clinicians had clinically suspected pHI as well as all cases of clinically important traumatic brain injuries (death, neurosurgery, intubation >24 h, admission >2 days and abnormal computed tomography). RESULTS: Of 20 137 evaluable patients with a head injury, 21 (0.1%) were identified to have sustained a pHI. All injuries were of non-intentional nature, and there were no gunshot wounds. The mechanisms of injuries varied from falls, animal attack, motor vehicle crashes and impact with objects. Mean Glasgow Coma Scale on ED arrival was 10; 10 (48%) had a history of loss of consciousness, and 7 (33%) children were intubated pre-hospital or in the ED. Fourteen (67%) children underwent neurosurgery, two (10%) craniofacial surgery, and five (24%) were treated conservatively; four (19%) patients died. CONCLUSIONS: Paediatric pHIs are very rare in EDs in Australia and New Zealand but are associated with high morbidity and mortality. The absence of firearm-related injuries compared to North America is striking and may reflect Australian and New Zealand firearm regulations. PMID- 29579355 TI - The Role of ANA Determinations in Classification Criteria for SLE. AB - At present, an international group under the auspices of the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) is developing new criteria for the classification of patients with systemic lupus erythematosus (SLE) designed to be more sensitive and specific than existing criteria [1]. As discussed at the 2017 meeting of the ACR, an important feature of these criteria, which are based on a scoring system for clinical and laboratory domains, is the prominence of a positive antinuclear antibody (ANA) at a titer 1:80 or greater by immunofluorescence (IFA) as an entry criterion.

AB - : Alcoholic cirrhosis (AC) is a major cause of liver-related morbidity and mortality in the United States. Rising rates of alcohol use disorders in the United States will likely result in more alcoholic liver disease. Our aim was to determine the prevalence, health care use, and costs of AC among privately insured persons in the United States. We collected data from persons aged 18-64 with AC (identified by codes from the International Classification of Diseases, Ninth and Tenth Revisions) enrolled in the Truven MarketScan Commercial Claims and Encounters database (2009-2015). We determined yearly prevalence, weighted to the national employer-sponsored, privately insured population. Using competing risk analysis, we estimated event rates for portal hypertensive complications and estimated the association between AC and costs as well as admissions and readmissions. In 2015, 294,215 people had cirrhosis and 105,871 (36%) had AC. Mean age at AC diagnosis was 53.5 years, and 32% were women. Over the 7 years queried, estimated national cirrhosis prevalence rose from 0.19% to 0.27% (P < 0.001) and for AC from 0.07% to 0.10% (P < 0.001). Compared to non-AC, AC enrollees were significantly more likely to have portal hypertensive complications at diagnosis and higher yearly cirrhosis and alcohol-related admissions (25 excess cirrhosis admissions and 6.3 excess alcohol-related admissions per 100 enrollees) as well as all-cause readmissions. Per-person costs in the first year after diagnosis nearly doubled for AC versus non-AC persons (US$ 44,835 versus 23,319). CONCLUSION: In a nationally representative cohort of privately insured persons, AC enrollees were disproportionately sicker at presentation, were admitted and readmitted more often, and incurred nearly double the per-person health care costs compared to those with non-AC.

AB - OBJECTIVE: To assess the incidence of venous thromboembolic events (VTEs) in patients with idiopathic inflammatory myopathies (IIMs), to compare the incidence of VTEs in IIM to the incidence in the general population, and to identify patient categories at high risk and investigate the development of risk in relation to a diagnosis of IIM. METHODS: Using nationwide registers, we identified a cohort of 440 individuals with newly diagnosed IIM and 4,459 individuals from the general population. Patients with IIM were diagnosed between 2005 and 2011. The start of follow-up was the date of IIM diagnosis and the corresponding date in the general population. VTE was defined as hospital care with an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code indicating VTE, with a filled prescription for anticoagulant medication. Incidence rates including 95% confidence intervals (95% CIs) were calculated, and Cox proportional hazards models were used to compare the risk of VTE in patients with IIM to the risk in the general population. RESULTS: The incidence of VTEs was higher in patients with IIM than in the general population and was highest in patients who previously had cancer, who were ages >71 years when diagnosed with IIM, or who had dermatomyositis. The overall hazard ratio (HR) of VTE comparing the IIM cohort to the general population was 7.81 (95% CI 4.74, 12.85). The HR was highest the first year after IIM diagnosis, with HR 26.6 (95% CI 10.4, 68.0). CONCLUSION: Patients with IIM are at increased risk of VTE compared to the general population, especially during the first year after the diagnosis. Preventive measures should be focused on patients who previously have had cancer, who are ages >71 years when diagnosed, or who have dermatomyositis.

PMID- 29579359 TI - Hepatic Lipogenesis and Brain Fatty Acid Profile in Response to Different Dietary n6/n3 Ratios and DHA/EPA Supplementation in Streptozotocin Treated Rats. AB - SCOPE: We investigated the interaction between streptozotocin (STZ)-induced diabetes and dietary n6/n3 ratio, and its influence on lipogenesis. METHODS AND RESULTS: The animals were treated with STZ and fed with different dietary n6/n3 ratios: 1, 7, and 60, or supplemented with DHA/EPA. Gene expression was assessed by RT-PCR and protein expression by western blotting and immunohistochemistry. Fatty acid profile was determined by GC-MS. Pancreas and liver histology were assessed by hematoxylin and eosin (H&E) staining. STZ-induced characteristic changes in all STZ treated groups, including: increased blood glucose, decreased body mass, increased lipid peroxidation and CD36 expression, decreased 16:1n7 and 18:1n7, increases in 20:3n6, decreases in phospholipid (PL) content of 20:4n6, as well as decreases in the expression of SREBP1c, Delta-9-desaturase (Delta9D), and Delta-5-desaturase (Delta5D). Additionally, other changes occurred that were dependent on the n6/n3 ratio. Among the diabetic groups, the lower n6/n3 ratio caused higher lipid peroxidation and CD36 expression, a greater decrease in 20:4n6 and decreased Delta6-desaturase (Delta6D) expression, while the higher n6/n3 ratio caused increased partitioning of 20:4n6 into hepatic neutral lipids (NL), a decrease in 20:5n3 content, and increased beta-oxidation. CONCLUSION: Presented data suggest that the n6/n3 ratio could significantly influence lipogenesis, lipid peroxidation, and beta-oxidation in STZ-induced diabetes, which could have clinical significance. PMID- 29579360 TI - Use of capillary electrophoresis for characterisation of vinyl-terminated Au nanoprisms and nanooctahedra. AB - It is described a simple, rapid and efficient methodology to characterise and separate gold nanoprisms and nanooctahedra by capillary electrophoresis. This technique is suitable to distinguish between morphologies and it can be used as a powerful separation tool after a customised synthesis of both structures. This synthesis was carried out by amending two parameters, temperature and pH, and a sharp decrease was found in nanotriangles when temperature was increased from 70 up to 95 degrees C. However, when the synthesis was performed at a given temperature, an increase in pH did not promote an important change in isolation of any structure until pH = 9.5, critical in the final morphology of the nanoparticle. Gold nanoprisms and nanooctahedra were successfully separated by capillary electrophoresis according to differences in charge-to-mass ratio of the morphologies. Final particle morphology was confirmed by transmission electron microscopy analysis. Under optimal working conditions, a mixture containing both shapes of gold nanoparticles was initially injected and two major peaks were obtained for each structure. Capillary electrophoresis allowed to study pH and temperature influence on both morphologies. It was inferred that the ratio between triangles and octahedra decreased to a great extent when increasing both temperature and pH. PMID- 29579361 TI - Utility of the BRAF p.V600E immunoperoxidase stain in FNA direct smears and cell block preparations from patients with thyroid carcinoma. AB - BACKGROUND: The identification of BRAF mutations in thyroid cancer has prognostic and therapeutic implications. Although the gold standard for identifying BRAF mutations is molecular testing, the ability to perform BRAF p.V600E immunostaining on fine-needle aspiration (FNA) samples can facilitate the rapid triaging of patients to treatment options. METHODS: A total of 50 thyroid carcinoma FNA samples, including papillary (29 samples), poorly differentiated (10 samples), anaplastic (9 samples), and Hurthle cell (2 samples) carcinomas, with a known BRAF p.V600E mutation status were selected for the current study. Immunostaining was performed on smears and cell block sections using an anti-BRAF p.V600E antibody (clone VE1). The results were compared with the known mutation status obtained by molecular testing and/or immunostaining of surgical pathology material from the same patient. RESULTS: Of the total of 50 cases, 26 cases had smears available for the evaluation of BRAF p.V600E immunostaining; positive immunostaining was noted in 16 samples and negative immunostaining was noted in 4 samples, whereas 6 cases were equivocal. Of the 34 cases for which cell blocks were available for evaluation, BRAF p.V600E immunostaining was positive in 17 cases, negative in 16 cases, and equivocal in 1 case. The overall sensitivity and specificity of BRAF p.V600E immunostaining on the cell block preparation was 94.4% and 100%, respectively, whereas for the smears it was 80% and 63.6%, respectively. CONCLUSIONS: BRAF p.V600E immunostaining can be performed reliably on thyroid FNA cell block preparations. However, false-positive results on direct smears limit their utility and therefore need to be interpreted with caution. Cancer Cytopathol 2018;126:406-13. (c) 2018 American Cancer Society. PMID- 29579363 TI - Gout Severity, Socioeconomic Status, and Work Absence: A Cross-Sectional Study in Primary Care. AB - OBJECTIVE: To examine the association between gout severity and socioeconomic status (SES) and gout severity and work absence. METHODS: Postal questionnaires were sent to adult patients who were registered with 20 general practices and who had consultations regarding gout or had been prescribed allopurinol or colchicine in the preceding 2 years. Gout severity was defined using the following proxy measures: number of attacks, history of oligoarticular/polyarticular attacks, disease duration, and allopurinol use. SES was defined using the English index of multiple deprivation (area level) and using self-reported educational attainment (individual level). Work absence was defined as taking time off from work in the past 6 months because of gout. Adjusted odds ratios (ORadj ; 95% confidence intervals [95% CIs]) were calculated using logistic regression models (adjusted for age, sex, body mass index, gout severity, and comorbidities). RESULTS: A total of 1,184 completed questionnaires were returned. The mean age of patients was 65.6 years, and 84% were male. Not having attended further education ("further education" is defined as attendance after the statutory minimum school leaving age of 16 years) was associated with having had >=2 gout attacks in the last year (ORadj 0.54 [95% CI 0.36-0.81]) and oligoarticular/polyarticular attacks (ORadj 0.72 [95% CI 0.50-1.05]). Lower area-level deprivation was associated with fewer attacks (>=2) (ORadj 0.71 [95% CI 0.51-0.98]). Work absence was associated with having had >=2 gout attacks in the last year (ORadj 2.91 [95% CI 1.22- 6.92]), oligoarticular/polyarticular attacks (ORadj 3.10 [95% CI 1.46 6.61]), and shorter disease duration (>18 years) (ORadj 0.13 [95% CI 0.03-0.50]). CONCLUSION: Gout severity was associated with individual-level deprivation, countering the historic and negative perception of gout as a "rich man's disease." The association of gout severity with work absence reinforces the argument for earlier urate-lowering therapy to prevent attacks from becoming frequent and debilitating. PMID- 29579362 TI - Barriers to the recognition of medullary thyroid carcinoma on FNA: Implications relevant to the new American Thyroid Association guidelines. AB - BACKGROUND: The 2016 American Thyroid Association guidelines recommend multiple endocrine neoplasia testing and evaluation for pheochromocytoma before thyroidectomy after a thyroid fine-needle aspiration biopsy (FNA) is positive for medullary thyroid carcinoma (MTC). In the current study, the authors examined the reasons why FNA was unable to definitively diagnose MTC preoperatively, with attention to morphologic patterns that can be misleading. METHODS: Cases of MTC diagnosed on thyroid surgical resection for which there was a prior FNA and slides available for review were included (28 cases). Clinicopathologic data were collected. Slides were reviewed for numerous features blinded to the original FNA interpretation. Morphologic features were compared between concordant cases (20 cases) ("positive for MTC" or "suspicious for MTC") and discordant cases (4 cases) (any other interpretation). Three cases of microscopic MTC (measuring <1 cm) were excluded from statistical analysis, as was 1 case of sampling error (benign thyroid tissue). RESULTS: Nine men and 19 women were diagnosed with MTC. Four patients ultimately were diagnosed with multiple endocrine neoplasia, and 1 had bilateral pheochromocytomas. At the time of surgical excision, the mean tumor size was 2.3 cm (range, 0.1-7.5 cm). Review of morphologic features demonstrated that the discrepant cases were significantly more likely to have limiting factors (air-drying artifact/excess blood), a cohesive pattern, or to lack plasmacytoid morphology. None of the discordant cases had pseudoinclusions or amyloid (finding was not statistically significant). CONCLUSIONS: The majority (86%) of thyroid FNAs from patients with MTC are concordant (positive/suspicious for MTC). Patterns of failure include sampling error and limited typical morphologic features, particularly a lack of plasmacytoid morphology and cellular dyshesion. A high level of suspicion for MTC is critical to ensure patients receive appropriate preoperative testing. Cancer Cytopathol 2018;126:397-405. (c) 2018 American Cancer Society. PMID- 29579364 TI - ANA as an Entry Criterion in SLE Classification. AB - Thoughtful and eloquent as always, Drs. Pisetsky and Lipsky in their letter (1) highlight a critical point in the current SLE classification criteria project jointly supported by EULAR and ACR: if ANA positivity is to be the entry criterion, the sensitivity of the assay to detect ANA and that of ANA positivity for SLE are both important. Indeed, this issue has been a matter constantly discussed by the classification criteria steering committee since the beginning of the project. Our tenet is not that various ANA assays are comparable, but that ANA positivity is optimally positioned as an entry criterion for the classification of SLE (2).

AB - BACKGROUND: Many cancer survivors experience fatigue as a nagging symptom lasting years after treatment. To learn of the relevant biological pathways involved in fatigue among cancer survivors, the authors tested for an association between fatigue levels and leukocyte gene expression profiles and determined the specific mediating immune cell types. METHODS: A sample of 89 Hispanic/Latino adults aged 60.5 years, 62% of whom were male, who were diagnosed with colorectal cancer and were 2.9 years since diagnosis provided blood for transcriptome profiling and completed a validated measure of fatigue (Multidimensional Fatigue Symptom Inventory-Short Form). The authors applied genome-wide transcriptional profiling of leukocyte RNA to identify gene expression activity associated with fatigue, tested for the activity of specific transcription factors involved in previously established markers of inflammation and immunologic activation, and identified the specific cell types mediating these transcriptional alterations. RESULTS: In analyses adjusting for demographic and behavioral health risk factors, results linked fatigue with increased activation of B lymphocytes and CD8-positive T cells, as well as several transcription factors involved in immune activation (nuclear factor kappaB [NF-kappaB], signal transducer and activator of transcription [STAT], and cAMP responsive element-binding protein [CREB]). Results also replicated several specific genomic effects previously observed in fatigued cancer survivors, including upregulated expression of alpha-synuclein (SNCA) and hemoglobin subunits (HBA and HBB). CONCLUSIONS: Cancer survivors' heightened fatigue levels may be partially explained by activation of specific immune cell subsets, thereby providing a potential molecular biomarker for clinical interventions targeting the remediation of fatigue.

AB - OBJECTIVE: Pain catastrophizing is a common feature of chronic pain, including fibromyalgia (FM), and is strongly associated with amplified pain severity and disability. While previous neuroimaging studies have focused on evoked pain response modulation by catastrophizing, the brain mechanisms supporting pain catastrophizing itself are unknown. We designed a functional magnetic resonance imaging (fMRI)-based pain catastrophizing task whereby patients with chronic pain engaged in catastrophizing-related cognitions. We undertook this study to test our hypothesis that catastrophizing about clinical pain would be associated with amplified activation in nodes of the default mode network (DMN), which encode self-referential cognition and show altered functioning in chronic pain. METHODS: During fMRI, 31 FM patients reflected on how catastrophizing (CAT) statements (drawn from the Pain Catastrophizing Scale) impact their typical FM pain experience. Response to CAT statements was compared to response to matched neutral (NEU) statements. RESULTS: During statement reflection, higher fMRI signal during CAT statements than during NEU statements was found in several DMN brain areas, including the ventral (posterior) and dorsal (anterior) posterior cingulate cortex (vPCC and dPCC, respectively). Patients' ratings of CAT statement applicability were correlated solely with activity in the vPCC, a main DMN hub supporting self-referential cognition (r = 0.38, P < 0.05). Clinical pain severity was correlated solely with activity in the dPCC, a PCC subregion associated with cognitive control and sensorimotor processing (r = 0.38, P < 0.05). CONCLUSION: These findings provide evidence that the PCC encodes pain catastrophizing in FM and suggest distinct roles for different PCC subregions. Understanding the brain circuitry encoding pain catastrophizing in FM will prove to be important in identifying and evaluating the success of interventions targeting negative affect in chronic pain management.

AB - Metabolomic studies of body fluids show that immune-mediated inflammatory diseases such as rheumatoid arthritis (RA) are associated with metabolic disruption. This is likely to reflect the increased bioenergetic and biosynthetic demands of sustained inflammation and changes in nutrient and oxygen availability in damaged tissue. The synovial membrane lining layer is the principal site of inflammation in RA. Here, the resident cells are fibroblast-like synoviocytes (FLS) and synovial tissue macrophages, which are transformed toward overproduction of enzymes that degrade cartilage and bone and cytokines that promote immune cell infiltration. Recent studies have shown metabolic changes in both FLS and macrophages from RA patients, and these may be therapeutically targetable. However, because the origins and subset-specific functions of synoviocytes are poorly understood, and the signaling modules that control metabolic deviation in RA synovial cells are yet to be explored, significant additional research is needed to translate these findings to clinical application. Furthermore, in many inflamed tissues, different cell types can forge metabolic collaborations through solute carriers in their membranes to meet a high demand for energy or biomolecules. Such relationships are likely to exist in the synovium and have not been studied. Finally, it is not yet known whether metabolic change is a consequence of disease or whether primary changes to cellular metabolism might underlie or contribute to the pathogenesis of early stage disease. In this review article, we collate what is known about metabolism in synovial tissue cells and highlight future directions of research in this area.

AB - Many potential applications of quantum dots (QDs) can only be realized once the luminescence from single nanocrystals (NCs) is understood. These applications include the development of quantum logic devices, single-photon sources, long life LEDs, and single-molecule biolabels. At the single-nanocrystal level, random fluctuations in the QD photoluminescence occur, a phenomenon termed blinking. There are two competing models to explain this blinking: Auger recombination and surface trap induced recombination. Here we use lifetime scaling on core-shell chalcogenide NCs to demonstrate that both types of blinking occur in the same QDs. We prove that Auger-blinking can yield single-exponential on/off times in contrast to earlier work. The surface passivation strategy determines which blinking mechanism dominates. This study summarizes earlier studies on blinking mechanisms and provides some clues that stable single QDs can be engineered for optoelectronic applications. PMID- 29579377 TI - Quantitative Investigation of the Role of Intra-/Intercellular Dynamics in Bacterial Quorum Sensing. AB - Bacteria utilize diffusible signals to regulate population density-dependent coordinated gene expression in a process called quorum sensing (QS). While the intracellular regulatory mechanisms of QS are well-understood, the effect of spatiotemporal changes in the population configuration on the sensitivity and robustness of the QS response remains largely unexplored. Using a microfluidic device, we quantitatively characterized the emergent behavior of a population of swimming E. coli bacteria engineered with the lux QS system and a GFP reporter. We show that the QS activation time follows a power law with respect to bacterial population density, but this trend is disrupted significantly by microscale variations in population configuration and genetic circuit noise. We then developed a computational model that integrates population dynamics with genetic circuit dynamics to enable accurate (less than 7% error) quantitation of the bacterial QS activation time. Through modeling and experimental analyses, we show that changes in spatial configuration of swimming bacteria can drastically alter the QS activation time, by up to 22%. The integrative model developed herein also enables examination of the performance robustness of synthetic circuits with respect to growth rate, circuit sensitivity, and the population's initial size and spatial structure. Our framework facilitates quantitative tuning of microbial systems performance through rational engineering of synthetic ribosomal binding sites. We have demonstrated this through modulation of QS activation time over an order of magnitude. Altogether, we conclude that predictive engineering of QS based bacterial systems requires not only the precise temporal modulation of gene expression (intracellular dynamics) but also accounting for the spatiotemporal changes in population configuration (intercellular dynamics). PMID- 29579378 TI - Sensitive Rapid Fluorescence Polarization Immunoassay for Free Mycophenolic Acid Determination in Human Serum and Plasma. AB - In this Article, we describe a fluorescence polarization immunoassay (FPIA) using a new label-near-infrared fluorescent dye. The developed FPIA method was optimized for the rapid analysis of free mycophenolic acid (MPA) in plasma of transplanted patients. The approach is based on the fluorescence competitive assay between the target immunosuppressant and a novel emissive near-infrared fluorescent dye-tagged MPA and MPA-AO for the binding sites of the anti-MPA antibody. The fluorescent analogue of MPA exhibits emission at 654 nm upon excitation at 629 nm (lambdaexcmax) and shows a good photochemical stability and a significant emission quantum yield (0.16) in phosphate buffer media. Free mycophenolic acid was isolated from blood or plasma samples using ultrafiltration prior to analysis. The sample was incubated for 20 min with 5 MUg/mL of anti-MPA antibody and 1 nM of MPA-AO before the measurements. The developed FPIA displays a limit of detection of 0.8 ng/mL (10% binding inhibition) and a dynamic range of 1.7-39 ng/mL (20%-80% binding inhibition) in a PBST buffer, fitting the therapeutic requirements. The immunoassay selectivity was evaluated by measuring the cross-reactivity to other immunosuppressive drugs administered in combination with MPA (cyclosporin A and tacrolimus), as well as for the metabolite MPA glucuronide. The assay has been successfully applied to the analysis of free MPA in the blood of a heart-transplanted patient after oral administration of both mycophenolate mofetil (MMF) and tacrolimus, and the results have been compared with those obtained by rapid-resolution liquid chromatography with diode array detection (RRLC-DAD). PMID- 29579379 TI - Multiple Reaction Monitoring Tandem Mass Spectrometry Approach for the Identification of Biological Fluids at Crime Scene Investigations. AB - Knowledge of the nature of biofluids at a crime scene is just as important as DNA test to link the nature of the biofluid, the criminal act, and the dynamics of the crime. Identification of methods currently used for each biological fluid (blood, semen, saliva, urine) suffer from several limitations including instability of assayed biomolecules, and low selectivity and specificity; as an example of the latter issue, it is not possible to discriminate between alpha amylase 1 (present in saliva) and alpha-amylase 2 (present in semen and vaginal secretion. In this context, the aim of the work has been to provide a predictive protein signature characteristic of each biofluid by the recognition of specific peptides unique for each protein in a single analysis. A panel of four protein biomarkers for blood, four for saliva, five for semen, and two for urine has been monitored has been monitored by using a single multiple reaction monitoring (MRM) based method targeting concomitantly 46 different peptides. Then, The optimized method allows four biological matrices to be identified when present on their own or in 50:50 mixture with another biofluid. Finally, a valid strategy combining both DNA analysis and liquid chromatographic-tandem mass spectrometric multiple reaction monitoring (LC-MS-MRM) identification of biofluids on the same sample has been demonstrated to be particularly effective in forensic investigation of real trace evidence collected at a crime scene.

AB - It is well established that aberrant cellular biochemical activity is strongly linked to the formation and progression of various cancers. Assays that could aid in cancer diagnostics, assessing anticancer drug resistance, and in the discovery of new anticancer drugs are highly warranted. In recent years, a large number of small molecule-based fluorescent chemosensors have been developed for monitoring the activity of enzymes and small biomolecular constituents. These probes have shown several advantages over traditional methods, such as the ability to directly and selectively measure activity of their targets within complex cellular environments. This review will summarize recently developed fluorescent chemosensors that have potential applications in the field of cancer biology. PMID- 29579381 TI - Remote Control of Mammalian Cells with Heat-Triggered Gene Switches and Photothermal Pulse Trains. AB - Engineered T cells are transforming broad fields in biomedicine, yet our ability to control cellular activity at specific anatomical sites remains limited. Here we engineer thermal gene switches to allow spatial and remote control of transcriptional activity using pulses of heat. These gene switches are constructed from the heat shock protein HSP70B' (HSPA6) promoter, show negligible basal transcriptional activity, and activate within an elevated temperature window of 40-45 degrees C. Using engineered Jurkat T cells implanted in vivo, we use plasmonic photothermal heating to trigger gene expression at specific sites to levels greater than 200-fold. We show that delivery of heat as thermal pulse trains significantly increase cellular thermal tolerance compared to continuous heating curves with identical area-under-the-curve (AUC), enabling long-term control of gene expression in Jurkat T cells. This approach expands the toolkit of remotely controlled genetic devices for basic and translational applications in synthetic immunology. PMID- 29579382 TI - Identification of Lasso Peptide Topologies Using Native Nanoelectrospray Ionization-Trapped Ion Mobility Spectrometry-Mass Spectrometry. AB - Lasso peptides are a fascinating class of bioactive ribosomal natural products characterized by a mechanically interlocked topology. In contrast to their branched-cyclic forms, lasso peptides have higher stability and have become a scaffold for drug development. However, the identification and separation of lasso peptides from their unthreaded topoisomers (branched-cyclic peptides) is analytically challenging since the higher stability is based solely on differences in their tertiary structures. In the present work, a fast and effective workflow is proposed for the separation and identification of lasso from branched cyclic peptides based on differences in their mobility space under native nanoelectrospray ionization-trapped ion mobility spectrometry-mass spectrometry (nESI-TIMS-MS). The high mobility resolving power ( R) of TIMS resulted in the separation of lasso and branched-cyclic topoisomers ( R up to 250, 150 needed on average). The advantages of alkali metalation reagents (e.g., Na, K, and Cs salts) as a way to increase the analytical power of TIMS is demonstrated for topoisomers with similar mobilities as protonated species, efficiently turning the metal ion adduction into additional separation dimensions. PMID- 29579384 TI - High Mass Loading MnO2 with Hierarchical Nanostructures for Supercapacitors. AB - Metal oxides have attracted renewed interest as promising electrode materials for high energy density supercapacitors. However, the electrochemical performance of metal oxide materials deteriorates significantly with the increase of mass loading due to their moderate electronic and ionic conductivities. This limits their practical energy. Herein, we perform a morphology and phase-controlled electrodeposition of MnO2 with ultrahigh mass loading of 10 mg cm-2 on a carbon cloth substrate to achieve high overall capacitance without sacrificing the electrochemical performance. Under optimum conditions, a hierarchical nanostructured architecture was constructed by interconnection of primary two dimensional epsilon-MnO2 nanosheets and secondary one-dimensional alpha-MnO2 nanorod arrays. The specific hetero-nanostructures ensure facile ionic and electric transport in the entire electrode and maintain the structure stability during cycling. The hierarchically structured MnO2 electrode with high mass loading yields an outstanding areal capacitance of 3.04 F cm-2 (or a specific capacitance of 304 F g-1) at 3 mA cm-2 and an excellent rate capability comparable to those of low mass loading MnO2 electrodes. Finally, the aqueous and all-solid asymmetric supercapacitors (ASCs) assembled with our MnO2 cathode exhibit extremely high volumetric energy densities (8.3 mWh cm-3 at the power density of 0.28 W cm-3 for aqueous ASC and 8.0 mWh cm-3 at 0.65 W cm-3 for all solid ASC), superior to most state-of-the-art supercapacitors.

AB - A silver-catalyzed phosphorylation/cyclization cascade of N-allyl anilines was developed, allowing direct access to 3-phosphonoalkyl indolines, which were previously obtainable only via tedious procedures under harsh/toxic conditions. The unactivated double bond serves as the radical acceptor, whereas H phosphonates or -phosphine oxides act as the radical precursor. This protocol features simple operation, broad substrate scope, and great exo selectivity, and a gram-scale synthesis could be readily carried out. PMID- 29579383 TI - Engineered Charge Redistribution of Gp2 Proteins through Guided Diversity for Improved PET Imaging of Epidermal Growth Factor Receptor. AB - The Gp2 domain is a protein scaffold for synthetic ligand engineering. However, the native protein function results in a heterogeneous distribution of charge on the conserved surface, which may hinder further development and utility. We aim to modulate charge, without diminishing function, which is challenging in small proteins where each mutation is a significant fraction of protein structure. We constructed rationally guided combinatorial libraries with charge-neutralizing or charge-flipping mutations and sorted them, via yeast display and flow cytometry, for stability and target binding. Deep sequencing of functional variants revealed effective mutations both in clone-dependent contexts and broadly across binders to epidermal growth factor receptor (EGFR), insulin receptor, and immunoglobulin G. Functional mutants averaged 4.3 charge neutralizing mutations per domain while maintaining net negative charge. We evolved an EGFR-targeted Gp2 mutant that reduced charge density by 33%, maintained net charge, and improved charge distribution homogeneity while elevating thermal stability ( Tm = 87 +/- 1 degrees C), improving binding specificity, and maintaining affinity ( Kd = 8.8 +/ 0.6 nM). This molecule was conjugated with 1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid for 64Cu chelation and evaluated for physiological distribution in mice with xenografted A431 (EGFRhigh) and MDA-MB-435 (EGFRlow) tumors. Excised tissue gamma counting and positron emission tomography/computed tomography imaging revealed good EGFRhigh tumor signal (4.7 +/- 0.5%ID/g) at 2 h post-injection and molecular specificity evidenced by low uptake in EGFRlow tumors (0.6 +/- 0.1%ID/g, significantly lower than for non-charge-modified Gp2, p = 0.01). These results provide charge mutations for an improved Gp2 framework, validate an effective approach to charge engineering, and advance performance of physiological EGFR targeting for molecular imaging. PMID- 29579386 TI - Ab Initio Potential Energy Surfaces and Quantum Dynamics for Polyatomic Bimolecular Reactions. AB - There has been great progress in the development of potential energy surfaces (PESs) and quantum dynamics calculations in the gas phase. The establishment of a fitting procedure for highly accurate PESs and new developments in quantum reactive scattering on reliable PESs allow accurate characterization of reaction dynamics beyond triatomic systems. This review will give the recent development in our group in constructing ab initio PESs based on neural networks and the time dependent wave packet calculations for bimolecular reactions beyond three atoms. Bimolecular reactions of current interest to the community, namely, OH + H2, H + H2O, OH + CO, H + CH4, and Cl + CH4, are focused on. Quantum mechanical characterization of these reactions uncovers interesting dynamical phenomena with an unprecedented level of sophistication and has greatly advanced our understanding of polyatomic reaction dynamics. PMID- 29579387 TI - Generalized Density-Functional Tight-Binding Repulsive Potentials from Unsupervised Machine Learning. AB - We combine the approximate density-functional tight-binding (DFTB) method with unsupervised machine learning. This allows us to improve transferability and accuracy, make use of large quantum chemical data sets for the parametrization, and efficiently automatize the parametrization process of DFTB. For this purpose, generalized pair-potentials are introduced, where the chemical environment is included during the learning process, leading to more specific effective two-body potentials. We train on energies and forces of equilibrium and nonequilibrium structures of 2100 molecules, and test on ~130 000 organic molecules containing O, N, C, H, and F atoms. Atomization energies of the reference method can be reproduced within an error of ~2.6 kcal/mol, indicating drastic improvement over standard DFTB. PMID- 29579388 TI - Ordered Surface Structuring of Spherical Colloids with Binary Nanoparticle Superlattices. AB - Surface-patterning colloidal matter in the sub-10 nm regime generates exceptional functionality in biology and photonic and electronic materials. Techniques of artificially generating functional patterns in the small nanoscale advanced in a fascinating manner in the last several years. However, they remain often restricted to planar and noncolloidal substrates. Patterning colloidal matter in solution via bottom-up assembly of smaller subunits on larger core particles is highly challenging because it is necessary to force the subunits onto randomly moving objects. Consequently, the non-equilibrium conditions present during nanoparticle self-assembly are difficult to control to eventually achieve the desired material structures. Here, we describe the formation of surface patterns with intrinsic periodic repeats of 8.9 +/- 0.9 nm and less on hard, amorphous colloidal core particles by assembling binary nanoparticle superlattices on the curved particle surface. The colloidal environment is preserved during the entire bottom-up crystallization of variable building blocks (here, monodispersed 5 nm Au and 2.4 nm Pd nanoparticles (NPs) and 230 nm SiO2 core particles) into AB13 like, binary, and isotropic superlattice domains on the amorphous cores. The three-dimensional, bottom-up assembly technique is a new tool for patterning colloidal matter in the sub-10 nm surface regime for gaining access to multicomponent metamaterials for bionanoscience, photonics, and electronics. PMID- 29579389 TI - Salt- and pH-Triggered Helix-Coil Transition of Ionic Polypeptides under Physiology Conditions. AB - Controlling the helix-coil transition of polypeptides under physiological conditions is an attractive way toward smart functional materials. Here, we report the synthesis of a series of tertiary amine-functionalized ethylene glycol (EG x)-linked polypeptide electrolytes with their secondary structures tunable under physiological conditions. The resultant polymers, denoted as P(EG xDMA-Glu) ( x = 1, 2, and 3), show excellent aqueous solubility (>20 mg/mL) regardless of their charge states. Unlike poly-l-lysine that can form a helix only at pH above 10, P(EG xDMA-Glu) undergo a pH-dependent helix-coil switch with their transition points within the physiological range (pH ~5.3-6.5). Meanwhile, P(EG xDMA-Glu) exhibit an unusual salt-induced helical conformation presumably owing to the unique properties of EG x linkers. Together, the current work highlights the importance of fine-tuning the linker chemistry in achieving conformation switchable polypeptides and represents a facile approach toward stimuli responsive biopolymers for advanced biological applications. PMID- 29579390 TI - Discovery of a Novel Highly Selective Histamine H4 Receptor Antagonist for the Treatment of Atopic Dermatitis. AB - The histamine H4 receptor (H4R), a member of the G-protein coupled receptor family, has been considered as a potential therapeutic target for treating atopic dermatitis (AD). A large number of H4R antagonists have been disclosed, but no efficient agents controlling both pruritus and inflammation in AD have been developed yet. Here, we have discovered a novel class of orally available H4R antagonists showing strong anti-itching and anti-inflammation activity as well as excellent selectivity against off-targets. A pharmacophore-based virtual screening system constructed in-house successfully identified initial hit compound 9, and the subsequent homology model-guided optimization efficiently led us to discover pyrido[2,3- e]tetrazolo[1,5- a]pyrazine analogue 48 as a novel chemotype of a potent and highly selective H4R antagonist. Importantly, orally administered compound 48 exhibits remarkable efficacy on antipruritus and anti inflammation with a favorable pharmacokinetic (PK) profile in several mouse models of AD. Thus, these data strongly suggest that our compound 48 is a promising clinical candidate for treatment of AD. PMID- 29579391 TI - Modification of Bacterial Cellulose with Quaternary Ammonium Compounds Based on Fatty Acids and Amino Acids and the Effect on Antimicrobial Activity. AB - In the present work, bacterial cellulose (BC) membranes have been modified with bioactive compounds based on long chain dimer of C18 linoleic acid, referred to as the dilinoleic acid (DLA) and tyrosine (Tyr), a natural amino acid capable of forming noncovalent cation-pi interactions with positively charged ethylene diamine (EDA). This new compound, [EDA][DLA-Tyr], has been synthesized by simple coupling reaction, and its chemical structure was characterized by 1H NMR and Fourier transform infrared spectroscopy. The antimicrobial activity of a new compound against S. aureus and S. epidermidis, two cocci associated with skin and wound infections, was assessed. The [EDA][DLA-Tyr] impregnated BC exhibited strong and long-term antimicrobial activity against both staphylococcal species. The results showed a 57-66% and 56-60% reduction in S. aureus and S. epidermidis viability, respectively, depending on [EDA][DLA-Tyr] concentration used. Importantly, [EDA][DLA-Tyr] molecules were released gradually from the BC pellicle, while a reference antibiotic, erythromycine (ER), did not show any antibacterial activity against S. aureus and S. epidermidis after 48 h of soaking in deionized water. Thus, a combination of [EDA][DLA-Tyr] and BC could be a promising new class of wound dressing displaying both biocompatibility and antimicrobial activity. PMID- 29579392 TI - Template-Assisted Scalable Nanowire Networks. AB - Topological qubits based on Majorana Fermions have the potential to revolutionize the emerging field of quantum computing by making information processing significantly more robust to decoherence. Nanowires are a promising medium for hosting these kinds of qubits, though branched nanowires are needed to perform qubit manipulations. Here we report a gold-free templated growth of III-V nanowires by molecular beam epitaxy using an approach that enables patternable and highly regular branched nanowire arrays on a far greater scale than what has been reported thus far. Our approach relies on the lattice-mismatched growth of InAs on top of defect-free GaAs nanomembranes yielding laterally oriented, low defect InAs and InGaAs nanowires whose shapes are determined by surface and strain energy minimization. By controlling nanomembrane width and growth time, we demonstrate the formation of compositionally graded nanowires with cross-sections less than 50 nm. Scaling the nanowires below 20 nm leads to the formation of homogeneous InGaAs nanowires, which exhibit phase-coherent, quasi-1D quantum transport as shown by magnetoconductance measurements. These results are an important advance toward scalable topological quantum computing. PMID- 29579393 TI - Hybridization of Nitrogen Determines Hydrogen-Bond Acceptor Strength: Gas-Phase Comparison of Redshifts and Equilibrium Constants. AB - Gas-phase Fourier transform infrared spectroscopy and quantum chemical calculations are combined to illustrate the effect of hybridization on the hydrogen-bond acceptor strength of nitrogen by a comparison of nine bimolecular complexes. We present gas-phase results for the complexes of methanol, ethanol, and 2,2,2-trifluoroethanol with acetonitrile (sp-hybridized N) and find that the structure of these complexes is nearly linear and dominated by the OH...N hydrogen bond with no experimental indication of an OH-pi bonded structure. We compare experimental redshifts and equilibrium constants, obtained by combining experiments and theory, for these complexes to the corresponding complexes with pyridine (sp2-hybridized N) and trimethylamine (sp3-hybridized N). The comparison clearly illustrates that increasing the s-character of the nitrogen lone pair decreases the hydrogen-bond acceptor strength (sp3 > sp2 > sp). The observed trend correlates with the basicity of the acceptors and can be explained by the partial charge on the accepting nitrogen atom and the degree of localization of the nitrogen lone pair.

PMID- 29579395 TI - Polygenic Risk Scores in Clinical Psychology: Bridging Genomic Risk to Individual Differences. AB - Genomewide association studies (GWASs) across psychiatric phenotypes have shown that common genetic variants generally confer risk with small effect sizes (odds ratio < 1.1) that additively contribute to polygenic risk. Summary statistics derived from large discovery GWASs can be used to generate polygenic risk scores (PRS) in independent, target data sets to examine correlates of polygenic disorder liability (e.g., does genetic liability to schizophrenia predict cognition?). The intuitive appeal and generalizability of PRS have led to their widespread use and new insights into mechanisms of polygenic liability. However, when currently applied across traits they account for small amounts of variance (<3%), are relatively uninformative for clinical treatment, and, in isolation, provide no insight into molecular mechanisms. Larger GWASs are needed to increase the precision of PRS, and novel approaches integrating various data sources (e.g., multitrait analysis of GWASs) may improve the utility of current PRS. PMID- 29579396 TI - Role of Spdef in the Regulation of Muc5b Expression in the Airways of Naive and Mucoobstructed Mice. AB - Understanding how expression of airway secretory mucins MUC5B and MUC5AC is regulated in health and disease is important to elucidating the pathogenesis of mucoobstructive respiratory diseases. The transcription factor SPDEF (sterile alpha-motif pointed domain epithelial specific transcription factor) is a key regulator of MUC5AC, but its role in regulating MUC5B in health and in mucoobstructive lung diseases is unknown. Characterization of Spdef-deficient mice upper and lower airways demonstrated region-specific, Spdef-dependent regulation of basal Muc5b expression. Neonatal Spdef-deficient mice exhibited reductions in BAL Muc5ac and Muc5b. Adult Spdef-deficient mice partially phenocopied Muc5b-deficient mice as they exhibited reduced Muc5b in nasopharyngeal and airway epithelia but not in olfactory Bowman glands, 75% incidence of nasopharyngeal hair/mucus plugs, and mild bacterial otitis media, without defective mucociliary clearance in the nasopharynx. In contrast, tracheal mucociliary clearance was reduced in Spdef-deficient mice in the absence of lung disease. To evaluate the role of Spdef in the development and persistence of Muc5b-predominant mucoobstructive lung disease, Spdef-deficient mice were crossed with Scnn1b-transgenic (Scnn1b-Tg) mice, which exhibit airway surface dehydration induced airway mucus obstruction and inflammation. Spdef-deficient Scnn1b-Tg mice exhibited reduced Muc5ac, but not Muc5b, expression and BAL content. Airway mucus obstruction was not decreased in Spdef-deficient Scnn1b-Tg mice, consistent with Muc5b-dominant Scnn1b disease, but increased airway neutrophilia was observed compared with Spdef-sufficient Scnn1b-Tg mice. Collectively, these results indicate that Spdef regulates baseline Muc5b expression in respiratory epithelia but does not contribute to Muc5b regulation in a mouse model of Muc5b-predominant mucus obstruction caused by airway dehydration. PMID- 29579397 TI - Dicer1 Deficiency in the Idiopathic Pulmonary Fibrosis Fibroblastic Focus Promotes Fibrosis by Suppressing MicroRNA Biogenesis. AB - RATIONALE: The lung extracellular matrix (ECM) in idiopathic pulmonary fibrosis (IPF) mediates progression of fibrosis by decreasing fibroblast expression of miR 29 (microRNA-29), a master negative regulator of ECM production. The molecular mechanism is undefined. IPF-ECM is stiffer than normal. Stiffness drives fibroblast ECM production in a YAP (yes-associated protein)-dependent manner, and YAP is a known regulator of miR-29. Therefore, we tested the hypothesis that negative regulation of miR-29 by IPF-ECM was mediated by mechanotransduction of stiffness. OBJECTIVES: To determine how IPF-ECM negatively regulates miR-29. METHODS: We decellularized lung ECM using detergents and prepared polyacrylamide hydrogels of defined stiffness by varying acrylamide concentrations. Mechanistic studies were guided by immunohistochemistry of IPF lung and used cell culture, RNA-binding protein assays, and xenograft models. MEASUREMENTS AND MAIN RESULTS: Contrary to our hypothesis, we excluded fibroblast mechanotransduction of ECM stiffness as the primary mechanism deregulating miR-29. Instead, systematic examination of miR-29 biogenesis revealed a microRNA processing defect that impeded processing of miR-29 into its mature bioactive forms. Immunohistochemical analysis of the microRNA processing machinery in IPF lung specimens revealed decreased Dicer1 expression in the procollagen-rich myofibroblastic core of fibroblastic foci compared with the focus perimeter and adjacent alveolar walls. Mechanistically, IPF-ECM increased association of the Dicer1 transcript with RNA binding protein AUF1 (AU-binding factor 1), and Dicer1 knockdown conferred primary human lung fibroblasts with cell-autonomous fibrogenicity in zebrafish and mouse lung xenograft models. CONCLUSIONS: Our data identify suppression of fibroblast Dicer1 expression in the myofibroblast-rich IPF fibroblastic focus core as a central step in the mechanism by which the ECM sustains fibrosis progression in IPF. PMID- 29579398 TI - Response gene to complement 32 suppresses adipose tissue thermogenic genes through inhibiting beta3-adrenergic receptor/mTORC1 signaling. AB - Our previous studies have shown that response gene to complement (RGC)-32 deficiency (Rgc32-/-) protects mice from diet-induced obesity and increases thermogenic gene expression in adipose tissues. However, the underlying mechanisms by which RGC-32 regulates thermogenic gene expression remain to be determined. In the present study, RGC-32 expression in white adipose tissue (WAT) was suppressed during cold exposure-induced WAT browning. Rgc32-/- significantly increased thermogenic gene expression in the differentiated stromal vascular fraction (SVF) of inguinal (i)WAT and interscapular brown adipose tissue (BAT). Rgc32-/- and cold exposure regulated a common set of genes in iWAT, as shown by RNA sequencing data. Pathway enrichment analyses showed that Rgc32-/- down regulated PI3K/Akt signaling-related genes. Akt phosphorylation was also consistently decreased in Rgc32-/- iWAT, which led to an increase in beta3 adrenergic receptor (beta3-AR) expression and subsequent activation of mammalian target of rapamycin complex (mTORC)-1. beta3-AR antagonist SR 59230A and mTORC1 inhibitor rapamycin blocked Rgc32-/--induced thermogenic gene expression in both iWAT and interscapular BAT. These results indicate that RGC-32 suppresses adipose tissue thermogenic gene expression through down-regulation of beta3-AR expression and mTORC1 activity via a PI3K/Akt-dependent mechanism.-Chen, S., Mei, X., Yin, A., Yin, H., Cui, X.-B., Chen, S.-Y.

PMID- 29579399 TI - GSK3-activated STAT5 regulates expression of SFRPs to modulate adipogenesis. AB - Adipogenesis is a tightly regulated cellular process and is closely associated with obesity and its associated metabolic disorders, such as diabetes. Multiple transcription factors and signaling pathways are involved in the regulation of adipogenesis. Here, we report that glycogen synthase kinase (GSK3), which was reported to play an important role in many cellular processes, is essential to adipocyte differentiation at early and terminal differentiation phases. Mechanistically, GSK3 modulates adipogenesis through regulation of both canonical Wnt pathways, which involve Wnt/beta-catenin signaling, and noncanonical Wnt pathways, which include JNK and Ras-related C3 botulinum toxin substrate signaling. GSK3-regulated adipogenesis is also mediated by secreted frizzled related proteins (SFRPs), especially SFRP1, the canonical Wnt antagonist. The obesity-induced increase of Sfrp1 expression can be reversed by the GSK3 inhibitor. GSK3-regulated expression of Sfrp is mediated by signal transducer and activator of transcription 5 (STAT5). We demonstrated that GSK3 activates STAT5 through regulation of its phosphorylation to bind to the promoter of Sfrp genes and the peroxisome proliferator-activated receptor gamma gene to stimulate their expression, which could ultimately lead to a modulated adipogenic process. Our findings identify a GSK3/STAT5/SFRP/Wnt regulatory axis of adipogenesis and shed light on the molecular mechanism of adipogenesis by suggesting that different pathways and adipogenic regulators coordinately modulate adipocyte differentiation.-Wang L., Wang, Y., Meng, Y., Zhang, C., Di, L. GSK3-activated STAT5 regulates expression of SFRPs to modulate adipogenesis. PMID- 29579401 TI - Critical Comparison of Structured Contactors for Adsorption-Based Gas Separations. AB - Recent advances in adsorptive gas separations have focused on the development of porous materials with high operating capacity and selectivity, useful parameters that provide early guidance during the development of new materials. Although this material-focused work is necessary to advance the state of the art in adsorption science and engineering, a substantial problem remains: how to integrate these materials into a fixed bed to efficiently utilize the separation. Structured sorbent contactors can help manage kinetic and engineering factors associated with the separation, including pressure drop, sorption enthalpy effects, and external heat integration (for temperature swing adsorption, or TSA). In this review, we discuss monoliths and fiber sorbents as the two main classes of structured sorbent contactors; recent developments in their manufacture; advantages and disadvantages of each structure relative to each other and to pellet packed beds; recent developments in system modeling; and finally, critical needs in this area of research. PMID- 29579400 TI - Biomolecular Ultrasound and Sonogenetics. AB - Visualizing and modulating molecular and cellular processes occurring deep within living organisms is fundamental to our study of basic biology and disease. Currently, the most sophisticated tools available to dynamically monitor and control cellular events rely on light-responsive proteins, which are difficult to use outside of optically transparent model systems, cultured cells, or surgically accessed regions owing to strong scattering of light by biological tissue. In contrast, ultrasound is a widely used medical imaging and therapeutic modality that enables the observation and perturbation of internal anatomy and physiology but has historically had limited ability to monitor and control specific cellular processes. Recent advances are beginning to address this limitation through the development of biomolecular tools that allow ultrasound to connect directly to cellular functions such as gene expression. Driven by the discovery and engineering of new contrast agents, reporter genes, and bioswitches, the nascent field of biomolecular ultrasound carries a wave of exciting opportunities. PMID- 29579403 TI - Stable Radical Materials for Energy Applications. AB - Although less studied than their closed-shell counterparts, materials containing stable open-shell chemistries have played a key role in many energy storage and energy conversion devices. In particular, the oxidation-reduction (redox) properties of these stable radicals have made them a substantial contributor to the progress of organic batteries. Moreover, the use of radical-based materials in photovoltaic devices and thermoelectric systems has allowed for these emerging molecules to have impacts in the energy conversion realm. Additionally, the unique doublet states of radical-based materials provide access to otherwise inaccessible spin states in optoelectronic devices, offering many new opportunities for efficient usage of energy in light-emitting devices. Here, we review the current state of the art regarding the molecular design, synthesis, and application of stable radicals in these energy-related applications. Finally, we point to fundamental and applied arenas of future promise for these designer open-shell molecules, which have only just begun to be evaluated in full.

AB - In the United States, regulatory science is the science of developing new tools, standards, and approaches to assess the safety, efficacy, quality, and performance of all Food and Drug Administration-regulated products. Good regulatory science facilitates consumer access to innovative medical devices that are safe and effective throughout the Total Product Life Cycle (TPLC). Because the need to measure things is fundamental to the regulatory science of medical devices, analytical chemistry plays an important role, contributing to medical device technology in two ways: It can be an integral part of an innovative medical device (e.g., diagnostic devices), and it can be used to support medical device development throughout the TPLC. In this review, we focus on analytical chemistry as a tool for the regulatory science of medical devices. We highlight recent progress in companion diagnostics, medical devices on chips for preclinical testing, mass spectrometry for postmarket monitoring, and detection/characterization of bacterial biofilm to prevent infections. PMID- 29579405 TI - Boron Doped Diamond: A Designer Electrode Material for the Twenty-First Century. AB - Boron doped diamond (BDD) is continuing to find numerous electrochemical applications across a diverse range of fields due to its unique properties, such as having a wide solvent window, low capacitance, and reduced resistance to fouling and mechanical robustness. In this review, we showcase the latest developments in the BDD electrochemical field. These are driven by a greater understanding of the relationship between material (surface) properties, required electrochemical performance, and improvements in synthetic growth/fabrication procedures, including material postprocessing. This has resulted in the production of BDD structures with the required function and geometry for the application of interest, making BDD a truly designer material. Current research areas range from in vivo bioelectrochemistry and neuronal/retinal stimulation to improved electroanalysis, advanced oxidation processes, supercapacitors, and the development of hybrid electrochemical-spectroscopic- and temperature-based technology aimed at enhancing electrochemical performance and understanding. PMID- 29579406 TI - A Life in Food: A Grain of Salt and Some Humble Pie. AB - From my senior school days, I had wanted to pursue a career in food. In quite what capacity I was not too sure. So my starting points were within the fields of animal nutrition before moving for the major part of my career to medical schools to study human nutrition and health. My career scientific achievements lie within the Kuhnian spectrum of normal science, but within that normality, I was always one to challenge conventional wisdom. An academic career is about more than just research. It is about teaching and not just the minutiae of nutrition, but about life and living, about challenges and failures. Reflecting on the experience of that career, my advice to early stage researchers is this: Be patient, determined, and resilient in the very early stages. Hold no fear of change and be courageous in challenging conventional wisdom. Always favor openness and collaboration and always seek to help others. Citation indices are important to your career, but these other avenues that I advise you to follow are what you will eventually be most proud of. PMID- 29579402 TI - Biodegradable Polymeric Nanoparticles for Therapeutic Cancer Treatments. AB - Polymeric nanoparticles have tremendous potential to improve the efficacy of therapeutic cancer treatments by facilitating targeted delivery to a desired site. The physical and chemical properties of polymers can be tuned to accomplish delivery across the multiple biological barriers required to reach diverse subsets of cells. The use of biodegradable polymers as nanocarriers is especially attractive, as these materials can be designed to break down in physiological conditions and engineered to exhibit triggered functionality when at a particular location or activated by an external source. We present how biodegradable polymers can be engineered as drug delivery systems to target the tumor microenvironment in multiple ways. These nanomedicines can target cancer cells directly, the blood vessels that supply the nutrients and oxygen that support tumor growth, and immune cells to promote anticancer immunotherapy. PMID- 29579407 TI - Modulatory effect of curcumin on ketamine-induced toxicity in rat thymocytes: Involvement of reactive oxygen species (ROS) and the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) pathway. AB - Ketamine is a widely used anesthetic in pediatric clinical practice. Previous studies have demonstrated that ketamine induces neurotoxicity and has a modulatory effect on the cells of the immune system. Here, we evaluated the potential protective effect and underlying mechanisms of natural phenolic compound curcumin against ketamine-induced toxicity in rat thymocytes. Rat thymocytes were exposed to 100 uM ketamine alone or combined with increasing concentrations of curcumin (0.3, 1, and 3 MUM) for 24 hours. Cell viability was analyzed with CCK-8 assay kit. Apoptosis was analyzed using flow cytometry and propidium iodide as well as Z-VAD-FMK and Z-LEHD-FMK inhibitors. Reactive oxygen species (ROS) production and mitochondrial membrane potential [MMP] were measured by flow cytometry. Colorimetric assay with DEVD-pNA substrate was used for assessing caspase-3 activity. Involvement of phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway was tested with Wortmannin inhibitor. Ketamine induced toxicity in cells, increased the number of hypodiploid cells, caspase-3 activity and ROS production, and inhibited the MMP. Co-incubation of higher concentrations of curcumin (1 and 3 MUM) with ketamine markedly decreased cytotoxicity, apoptosis rate, caspase-3 activity, and ROS production in rat thymocytes, and increased the MMP. Application of Z-VAD-FMK (a pan caspase inhibitor) or Z-LEHD-FMK (caspase-9 inhibitor) with ketamine effectively attenuated the ketamine-induced apoptosis in rat thymocytes. Administration of Wortmannin (a PI3K inhibitor) with curcumin and ketamine significantly decreased the protective effect of curcumin on rat thymocytes. Our results indicate that ketamine-induced toxicity in rat thymocytes mainly occurs through the mitochondria-mediated apoptotic pathway and that the PI3K/Akt signaling pathway is involved in the anti-apoptotic effect of curcumin. PMID- 29579408 TI - Analysis of the association between CFH Y402H polymorphism and response to intravitreal ranibizumab in patients with neovascular age-related macular degeneration (nAMD). AB - Pharmacogenetic studies indicate that a variable response to anti-vascular endothelial growth factor (VEGF) therapy in patients with neovascular form of AMD (nAMD) may be due to polymorphisms in the complement factor H gene (CFH). This study is the first to investigate the association between CFH Y402H polymorphism and the response to ranibizumab therapy in Malaysian patients with nAMD. We included 134 patients with nAMD, examined between September 2014 and February 2016. The diagnosis of nAMD was confirmed by ophthalmologic examination, before ranibizumab therapy was started. Each patient received an intravitreal injection of 0.5 mg/0.05 ml ranibizumab following a treat-and-extend (TE) regimen. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) were recorded after 3 and 6 months following the first injection and compared with the baseline values. Genotyping of Y402H (rs1061170) polymorphism was performed using PCR-RFLP and the amplified product was digested with MluCI restriction enzyme. Association between the Y402H genotypes and response to treatment was determined by a logistic regression analysis of responder (n = 49) and non-responder (n = 84) group. Significantly worse mean BCVA was observed for the CC genotype compared to the TT + CT genotype in the total sample after 6-month follow-up (p = 0.018). Comparing the baseline and 6-month point measurements, improved mean BCVA was observed in responder group, while worse mean BCVA was recorded for non-responder group. However, our regression analysis, adjusted for confounding factors, showed no significant association between the Y402H genotypes and response to treatment in nAMD patients under the recessive model (p > 0.05). Overall, our results suggest that factors other than Y402H polymorphism may be involved in the progression of nAMD after treatment with anti-VEGF agents, in Malaysian population. PMID- 29579409 TI - The effect of 131I-induced hypothyroidism on the levels of nitric oxide (NO), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), total nitric oxide synthase (NOS) activity, and expression of NOS isoforms in rats. AB - Accumulating evidence has shown that hypothyroidism affects the cardiovascular system, significantly increasing the incidence of cardiovascular diseases. In the present study we investigated the effect of radioactive iodine (I-131)-induced hypothyroidism on several parameters of vascular function, such as nitric oxide (NO), total nitric oxide synthase (NOS) activity and expression of NOS isoforms, as well as on interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) as indicators of inflammation, in rats. A dose of 150 uCi of 131-I was determined as optimal for establishing the model of hypothyroidism in rats. After administration of 131-I, at the end of month 1, 2, and 4 (n = 3 for each time point), NO, IL-6, and TNF-alpha in the serum and total NOS activity in the aorta were determined in 150 uCi group, compared to controls. The mRNA and protein expression of endothelial, neuronal, and inducible NOS (eNOS, nNOS, and iNOS) in the rat aorta was also estimated, using quantitative reverse transcription polymerase chain reaction and Western blot, respectively. The levels of IL-6 and TNF-alpha increased in 150 uCi group; the results were significant at the end of month 2 and 4 for IL-6, and at all time points for TNF-alpha. The levels of NO decreased significantly at the end of month 2 and 4 in 150 uCi group. The total NOS activity increased significantly in 150 uCi group, at all three time points. Significant changes in the mRNA and protein expression of all three NOS isoforms were observed in 150 uCi group compared to controls. NO, IL-6, TNF-alpha levels and NOS activity and expression are altered in hypothyroid state, and the underlying mechanism should be further investigated. PMID- 29579410 TI - Dose and administration protocol for FSH used for ovarian stimulation affect gene expression in sheep cumulus?oocyte complexes. AB - The present study evaluated the effect of four ovarian stimulation protocols on the follicular population and molecular status of cumulus-oocyte complexes (COCs). Twelve Santa Ines ewes (in a cross-over design) received 80 or 120mg FSH alone in a multiple-dose (MD80 and MD120) regimen or in combination with 300IU equine chorionic gonadotrophin (eCG) in a one-shot (OS80 and OS120) protocol. The follicular population, COC recovery rate, mean COCs per ewe and the rate of brilliant Cresyl blue-positive (BCB+) COCs were similar among treatments (P>0.05). The expression of markers of oocyte competence (ZAR1, zygote arrest 1; MATER, maternal antigen that embryo requires; GDF9, growth differentiation factor 9; BMP15, bone morphogenetic protein 15; Bcl-2, B-cell lymphoma 2; BAX, Bcl-2 associated X protein) and the steroidogenic pathway (ERalpha, oestrogen receptor alpha; LHr, LH receptor; FSHr, FSH receptor; STAR, steroidogenic acute regulatory protein) was affected by stimulation. Specifically, the expression of markers of the steroidogenic pathway was reduced with increasing FSH dose in the OS protocol. FSH at a dose of 80mg reduced the expression of FSHr and ERalpha in the OS versus MD protocol. Conversely, in MD protocol, only LHr was affected by increasing FSH dose. In conclusion, 80mg FSH in the MD or OS protocol was sufficient to promote the development of multiple follicles and obtain fully grown (BCB+) oocytes. The MD protocol may be more appropriate for the production of better-quality oocytes. PMID- 29579411 TI - Comparative expression of PEDF and VEGF in human epidermal keratinocytes and dermal fibroblasts: from normal skin to psoriasis. AB - Vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) have been shown to keep angiogenesis activation and inhibition in balance in normal and pathological conditions. In this study, we examined the expression of VEGF and PEDF in keratinocytes and fibroblasts from normal and psoriatic skin to evaluate their potential roles and interactions in the development of psoriasis. The expression of VEGF and PEDF was detected in normal and psoriatic skin ex vivo and in co-cultured keratinocytes and fibroblasts in vitro, and increased in keratinocytes and fibroblasts from psoriatic skin compared with those cells from normal skin. Our results suggest that PEDF act as a multipotent factor in the skin and the imbalance of PEDF and VEGF may be responsible for the transformation from normal skin to psoriasis. PMID- 29579412 TI - Urine biomarkers in the early stages of diseases: current status and perspective. AB - As a noninvasive and easily available biological fluid, the urine is becoming an important source for disease biomarker study. Change is essential for the usefulness of a biomarker. Without homeostasis mechanisms, urine can accommodate more changes, especially in the early stages of diseases. In this review, we summarize current status and discuss perspectives on the discovery of urine biomarkers in the early stages of diseases. We emphasize the advantages of urine biomarkers compared to plasma biomarkers for the diagnosis of diseases at early stages, propose a urine biomarker research roadmap, and highlight a novel membrane storage technique that enables large-scale urine sample collection and storage efficiently and economically. It is anticipated that urine biomarker studies will greatly promote early diagnosis, prevention, treatment, and prognosis of a variety of diseases, and provide strong support for translational and precision medicine. PMID- 29579413 TI - The unusual nutritional and toxin-related underproduction anemias: approaching the riddle beyond iron, cobalamin, and folate. AB - "Anemias beyond iron, vitamin B12, and folate deficiencies" covers a wide array of everything which lies beyond commonly seen anemias caused by deficiencies of three micronutrients. Although anemias due to deficiencies of iron, B12, and folate are common in daily practice and account for at least one-third of anemia etiologies in older adults, it is not uncommon to encounter other nutritional and toxin-induced underproduction anemias. The combination of thorough clinical examination, careful peripheral blood smear review, and judicious selection of supporting laboratory studies is typically sufficient to make an assertive diagnosis of those cases. Moreover, the recognition of overlapping features with primary hematologic disorders and the diagnostic limitations of conventional testing are important for clinicians to determine when to refer to a hematologist. Herein, we discuss clinical features and diagnostic approaches to unusual underproduction anemias due to deficiencies of vitamin B6 and copper, and toxic effects of alcohol and lead.

AB - The inflammatory myopathies, which include dermatomyositis, polymyositis, and the immune-mediated necrotizing myopathies, are a heterogeneous group of autoimmune diseases that manifest with muscle, skin, or lung damage. Collectively, these autoimmune diseases result from loss of tolerance to a select group of self antigens, although the precise mechanism through which this occurs is not known. Infection, malignancy, and certain medications including statins and the immune checkpoint inhibitors used in cancer therapy have been identified as potential immunologic triggers of the inflammatory myopathies. Some of these triggers are classically associated with specific myositis-specific autoantibodies (MSAs). The strong association between certain triggers and MSAs provides insights into how an immunologic event can lead to loss of tolerance to specific self-antigens, resulting in autoimmune disease. In this review, we discuss the proposed triggers of the inflammatory myopathies and their associations with MSAs, and provide insights into how these triggers may result in the inflammatory myopathies.

AB - There is a new paradigm that preventing tuberculosis (TB) and addressing the reservoir of latent TB infection in combination with curing all TB cases is essential to accelerate the decline of TB rates and ending TB by 2050. However, complacency and incremental change eludes radical policy transformation needed to meet global targets. This essay explores current attitudes, policy disparities between high and lower burden settings, and what changes are needed to remove the obstacles to progress. PMID- 29579423 TI - Modalities to monitor the treatment response in tuberculosis. AB - Considering the global epidemic of drug resistance in Mycobacterium tuberculosis, early and accurate diagnosis as well as prompt initiation of antitubercular therapy (ATT) forms the mainstay of tuberculosis control programs. Patients on ATT may develop treatment failure due to diverse reasons including emergence of drug resistance in the host during the course of therapy. Monitoring the timely response to treatment in such cases has a significant role in rapid identification of drug resistant strains and institution of change of regimen to further decrease the morbidity and mortality associated with the disease. Furthermore, availability of faster surrogate end points to assess treatment efficacy, disease activity, cure, and relapse is one of the crucial requirements for undertaking innovative clinical trials related to TB. The article presents here the compilation of currently available methods for monitoring the treatment response in pulmonary as well as extrapulmonary TB. PMID- 29579424 TI - A selective and sensitive high performance liquid chromatography assay for the determination of cycloserine in human plasma. AB - BACKGROUND: Cycloserine (CYC) is a second line antitubercular drug that is used for the treatment of multidrug resistant tuberculosis (MDR-TB) along with other antitubercular agents and is often used in developing countries. Monitoring CYC levels in plasma could be useful in the clinical management of patients with MDR TB. A high performance liquid chromatography method for the determination of CYC in human plasma was developed. METHODS: The method involved extraction of the sample using solid phase extraction cartridges and analysis of the extracted sample using a reverse phase T3 column (150mm) and detection at 240nm with Photo Diode Array (PDA) detector. The chromatogram was run for 15min at a flow rate of 0.4ml/min at 30 degrees C. RESULTS AND CONCLUSION: The assay was specific for CYC and linear from 5.0 to 50.0MUg/ml. The relative standard deviations of within- and between-day assays were less than 10%. Recovery of CYC ranged from 102% to 109%. The interference of other second line anti-TB drugs in the assay of CYC was ruled out. The assay spans the concentration range of clinical interest. The specificity and sensitivity of this assay makes it highly suitable for pharmacokinetic studies. PMID- 29579425 TI - Knowledge of private practitioners of Bangalore city in diagnosis, treatment of pulmonary tuberculosis and compliance with case notification. AB - One hundred and twenty-nine qualified private practitioners (PPs) were assessed on their knowledge in diagnosis of pulmonary tuberculosis (PTB), treatment of a new drug sensitive PTB case and practices of case notification, using semi structured questionnaire. About 20% had adequate knowledge of diagnosis, 29% of treatment regimen, 54% the need for Direct Observation Treatment and 57% about role of sputum smear examination in monitoring treatment response. Of 85 (68%) PPs who had diagnosed any TB case during last two years, 54 (64%) had practised notification. These findings suggest the need for upgrading knowledge of PPs in TB diagnosis, treatment and notification. PMID- 29579426 TI - Prevalence of pulmonary tuberculosis among adults in selected slums of Delhi city. AB - BACKGROUND: A survey was carried out to estimate the point prevalence of bacteriologically positive pulmonary tuberculosis (PTB) among persons >=15 years of age residing in Jhuggi-Jhopri (JJ) colonies - urban slums in Delhi, India implementing Directly Observed Treatment strategy since 1998. METHODS: Among 12 JJ colonies selected by simple random sampling, persons having persistent cough for >=2 weeks at the time of the survey or cough of any duration along with history of contact/currently on ant-TB treatment/known HIV positive were subjected to sputum examination - 2 specimens, by smear microscopy for Acid Fast Bacilli and culture for Mycobacterium tuberculosis. Persons with at least one specimen positive were labelled as bacteriologically confirmed PTB. Prevalence was estimated after imputing missing values to correct bias introduced by incompleteness of data and corrected for non-screening by X-ray by a multiplication factor derived from recently conducted surveys. RESULTS: Of 40,756 persons registered, 40,529 (99.4%) were screened. Of them, 691 (2%) were eligible for sputum examination. Spot specimens were collected from 659 (99.2%) and early morning sputum specimens from 647 (98.1%). Using screening by interview alone, prevalence of bacteriologically positive PTB in persons >=15 years of age was estimated at 160.4 (123.7-197.1) per 100,000 populations and210.0 (CI: 162.5 258.2) after correcting for non-screening by X-ray. CONCLUSION: Observed prevalence suggests further strengthening of TB control program in urban slums. PMID- 29579427 TI - Factors predicting treatment success in multi-drug resistant tuberculosis patients treated under programmatic conditions. AB - BACKGROUND: Treatment success in multi-drug resistant tuberculosis under programmatic conditions has been far from satisfactory. Knowledge of the factors predicting treatment outcome can guide us to take appropriate corrective measures for better results. However, there is a scarcity of data on these predictors in Indian patients. The present study was sought to evaluate association of different patient and disease specific factors with treatment outcome in MDR-TB patients. METHODS: It was a retrospective study that involved evaluation of data of MDR-TB patients who were started on Cat-IV treatment between January 2012 and December 2014. Medical records of 256 patients were scrutinized and necessary information on possible predicting factors like age, gender, body mass index, co morbidities, previous TB treatment, blood investigations, treatment adherence, culture conversion time, etc. was retrieved. These factors were analyzed for their possible association with treatment outcome. RESULTS: Of the 256 patients, 132 (51.6%) achieved successful outcome after Cat-IV anti-TB regimen. On multivariate logistic regression analysis age (adjusted OR=0.95; 95% CI 0.91 0.98; p=0.01), serum albumin level (adjusted OR=3.71; 95% CI: 1.22-11.3; p=0.02) and treatment adherence (adjusted OR=4.52; 95% CI: 1.2-16.6; p=0.02) were independently associated with treatment success. Co-morbidities like diabetes and alcoholism and previous anti-TB treatment didn't affect the treatment end result significantly. CONCLUSION: The treatment outcome in MDR-TB has not significantly improved since the inception of DOTS-Plus strategy. Interventions to improve nutrition and treatment adherence might help to improve the success rate in MDR TB treatment. PMID- 29579428 TI - Socio-demographic profile and outcome of TB patients registered at DTC Rewa of Central India. AB - BACKGROUND: Tuberculosis is a specific infectious disease caused by Mycobacterium tuberculosis. The disease is usually chronic with cardinal features such as persistent cough with or without expectoration, intermittent fever, and loss of appetite, weight loss, chest pain and hemoptysis. OBJECTIVE: (1) To assess the socio-demographic profile of the patients attending DOTS Center. (2) To assess outcome of treatment under DOTS Center. METHODOLOGY: This is a Prospective Longitudinal study conducted among the patients attending DOTS center of DTC located at S.G.M.H. campus Rewa Madhya Pradesh Central India, during the last quarter of 2014, Study Duration: One year and two months i.e. starting from 1st September 2014 to 31st October 2015; total study sample size consisted of 137 patients who were newly registered during the last quarter of 2014 (from 1st October to 31st December 2014) at DOTS Center of DTC. After applying inclusion and exclusion criteria, a total of 133 newly registered patients were enrolled that can be considered as total sample size in the present study. RESULT: Study population comprises a total of 133 patients; out of which 84 (63.15%) were male and 49 (36.84%) were female. In both most common age group are 21-30 year were 41 (30.82%) patients and least common was pediatric TB in age group <10 year were 10 (7.51%) patients, lower socio-economic class (class-V) 53.38% followed by class IV or Lower middle class 29.32%, only 1.5% were from upper class. 96 (72.18%) patients were of category-I patient and 37 (27.81%) were category-II patient, 51 (38.34%) patients were cured, 70 (52.63%) had their treatment completed, so overall treatment success rate was 90.97%; in that, 2 cases were (1.50%) failure, 4 (3%) defaulters, 2 (1.50%) died during treatment and 4 (3%) were transferred out. CONCLUSION: Study concluded that most of the patients belonged to lower socioeconomic status and in productive age group so it will increase the economic burden over the family; therefore, after increasing the living standard the outcome of disease becomes favorable. PMID- 29579429 TI - Tuberculosis related stigma and its effect on the delay for sputum examination under the Revised National Tuberculosis Control Program in India. AB - BACKGROUND: One major barrier to achieve goal of tuberculosis (TB) control program globally, is the stigma attached to the disease. Perceived stigma can delay sputum test in time. Delay will lead to spread of infection in the community. There is no scientific information available in India exactly looking into the association between delay in sputum examination and stigma. AIM: We conducted a study in rural West Bengal among persons with cough for 2 weeks or more to assess their level of stigma, its influence on delay for sputum test and identify factors those shape the level of stigma. METHODS: A community based cross sectional survey was conducted from February to June 2015 in West Bengal, India. We interviewed 135 persons of 15-60 years. Data were collected using a pretested structured questionnaire. Chi-square and logistic regression analysis were done using SPSS 23.0 statistical software. RESULTS: Among the 'lower stigma' group (score 4-24), 'delay' (14-25 days) is found among 46.2% respondents and 'much delay' (26-120 days) among 53.8%. Among the 'higher stigma' (score 25-36) group, 'delay' is found among 20.5% respondents and 'much delay' among 79.5%. Persons with lower stigma are 0.17 times likely to delay than persons with higher stigma [adjusted odds ratio (AOR): 0.17 (0.044-0.668), p=0.011)]. Important influencers of stigma are caste [AOR: 5.90 (1.66-20.90), p=0.006], number of family members [AOR: 3.46 (1.08-11.06), p=0.009] and residence in urban or rural [AOR: 3.97 (1.03-15.27), p=0.045]. CONCLUSION: Revised National Tuberculosis Control Program in India should de-stigmatize the community giving priorities to lower castes, big families and rural areas. PMID- 29579430 TI - Expression profile of CXCL12 chemokine during M. tuberculosis infection with different therapeutic interventions in guinea pig. AB - Mycobacterium indicus pranii (MIP) already established as an immune-modulator in mycobacterial infections generates immune response by acting on CXC chemokines. In the present study, the immunomodulatory effect of MIP in conjunction with chemotherapy against M.tb infection was evaluated by colony forming units (CFUs) following aerosol infection to guinea pig and by measuring CXCL12 chemokine expression using q-PCR and in situ RT-PCR. Different experimental groups included, infection (Rv), immunoprophylaxis (RvMw), chemotherapy (RvCh) and combination of immunoprophylaxis+chemotherapy (RvChMw) group and normal healthy (NH) group. In the combination of immunoprophylaxis+chemotherapy (RvChMw) group, the CFU counts reduced significantly (p<0.001) at 4th week of infection as compared to other treated groups (RvMw and RvCh group). The expression of CXCL12 was recorded in all the treated groups of animals. The study demonstrated suppressed expression of CXCL 12 in both immunoprophylaxis as well as chemotherapy groups (6th and 8th week) that become elevated in immunoprophylaxis plus chemotherapy group (10th week), at which time point no CFUs were detected in RvCh and RvChMw group. The findings indicate that the expression of CXCL12 is associated with good response to anti - tubercular treatment. Thus, prior immunization with MIP appears to show good immunomodulatory effect to release CXCL12 chemokine during infection and also correlates with enhanced effect to chemotherapy. PMID- 29579431 TI - Quality of life of diabetic patients with smear positive PTB in southeastern Iran: A cross-sectional study in a poor region of Iran. AB - BACKGROUND: The quality of life is an important indicator of quality of care in chronic diseases such as diabetes and TB. The present research is conducted with an aim to assess the Quality of Life of Diabetic Patients with Smear Positive PTB. METHODS: This cross-sectional study was conducted on 62 diabetic patients with smear positive PTB from January to May 2016 in a diabetes clinic in Zahedan city (southeast of Iran). A simple random sampling method was used in this study. Instrument for data collection was quality of life (SF-36) questioner. RESULTS: Total quality of life score was 48 that showed an average level of quality of life. Sixty-five patients with diabetes and affected by smear positive pulmonary tuberculosis (PTB) with the average age of 51.30+/-10.84 years participated in this research. Four patients (0.06%) suffered from type 1 diabetes and 58 (94%) from type 2 diabetes, and all of them were smear positive PTB patients. Study of their quality of life revealed that, in general, the average scores for quality of life in the two main subgroups of physical health and mental health were lower than the average and, among the eight studied dimensions, the highest scores were those for physical activity (60+/-14.23) and the lowest (31.42+/-12.14) for general health in the subgroup of physical health. CONCLUSION: Results indicated that the patients had a low quality of life although they received the care and treatments that are effective in patients with diabetes and suffering from smear positive PTB.

Asian clinical studies describing meningitis in people living with HIV are scarce. We describe the clinical features of meningitis in 116 HIV seropositive patients from a tertiary hospital in India as a cross-sectional observational study. The mean age of the patients in our study was 35+/-9 years with 70.6% of them being men. Eighty-five percent of the patients had an altered sensorium during the illness. Tuberculous meningitis [82.6%] was the most common cause. Clinical features varied by aetiology. Cranial nerve deficits [40%] were common in Cryptococcal meningitis. Hydrocephalus [3%], infarcts [15.9%] and IntraCranial Space Occupying Lesions (ICSOLs) [39.1%] were common in tuberculous meningitis.

AB - Airborne infections are major public health concern especially in hospitals and public spaces in a highly populated country like India. Generating awareness about good infection control practices among common man and health care workers are important steps in curtailing transmission of air borne infections. In this study we were trying to assess the awareness of airborne infection control measures among patients, bystanders and healthcare workers in a tertiary care hospital at Kochi, Kerala. Self-administered questionnaire which included 10 questions for health care staff and 12 questions for lay men prepared on the basis of NAIC and NCDC guideline were given to the study participants. 143 health care staff and 332 laymen were participated in the study. In both groups majority of the responses were correct. However, only a small proportion of health care staff correctly answered fast tracking of a patient with TB (14.7%) and minimum air exchanges in air-conditioned settings (15.4%). Among laymen only a few correctly identified ideal place for sputum collection (43.3%) and role of hand washing in preventing flu (36.4%). Overall more intervention needed in improving awareness about good infection control practices among both health care staff and laymen.

We report a rare case of a 62-year-old man with hypercalcemia due to hepatic tuberculosis. The diagnosis was based on laparoscopic and a histopathological examination. After treatment with anti tuberculosis medication, the patient's serum calcium levels were within normal limits. Tuberculosis needs to be excluded as a diagnosis in any febrile patient with hypercalcemia, especially in countries where tuberculosis is endemic.

AB - Tubercular esophagocutaneous fistula is a rare entity with only about five cases reported so far. It can be as a result of primary involvement of esophagus by tuberculosis or due to spread of infection from adjacent structures like lungs or mediastinal lymph nodes. The fistula usually heals with initiation of antitubercular therapy and surgery is rarely required. Here we report a case of 65-year-old diabetic male who developed esophagocutaneous fistula secondary to caseation of mediastinal lymph nodes and was successfully treated with antitubercular treatment.

PMID- 29579442 TI - Will Hospital Peer Grouping by Patient Socioeconomic Status Fix the Medicare Hospital Readmission Reduction Program or Create New Problems? AB - BACKGROUND: In 2016 the U.S. Congress directed the Centers for Medicare & Medicaid Services (CMS) to implement the 21st Century Cures Act to fix a flaw in the Hospital Readmissions Reduction Program (HRRP). One section of the Act is intended to remove bias in calculating penalties for hospitals treating large percentages of low socioeconomic status (SES) patients. A study was conducted to analyze the effect of the introduction of SES hospital peer groups on the number and distribution of the hospitals being penalized. METHODS: The CMS analysis files for the fiscal year 2017 HRRP final rule and Disproportionate Share Hospital adjustments were used to assign hospital peer groups. The median excess readmission ratios for hospital peer groups were calculated, and the resulting pattern of hospital penalties within peer groups was analyzed. RESULTS: The findings suggest that because CMS assigns individual HRRP penalties on six clinical conditions but proposes to assign hospitals to a single SES peer group based on all admissions, it will ignore substantial differences in the distribution of peer group medians across these conditions. For surgical cases, as expected, hospitals with fewer patients had higher readmission rates, while for medical cases, hospitals with fewer patients had fewer readmissions. These findings may result in distortion of the peer group adjustment intended to correct for SES. CONCLUSION: Hospital peer groups may create unintended redistributions of penalties through distortion of peer group medians. An observed relationship between lower-volume hospitals and fewer readmissions for medical conditions requires additional research to establish its basis. PMID- 29579443 TI - How Patient Partners Influence Quality Improvement Efforts. AB - BACKGROUND: There is growing acknowledgement that patients are key stakeholders in improving quality of medical care, yet a key barrier to integrating patients into quality improvement teams (QITs) as patient partners is the lack of evidence of their impact. This mixed-method study was conducted to identify the ways patient partners influence QITs and to document the extent of patient partners' impact. METHODS: Focus groups and in-depth interviews were conducted with 17 patient partners and 11 staff at WellSpan Health and Aligning Forces for Quality South Central Pennsylvania to identify the specific mechanisms through which patients influenced QIT efforts. Online surveys of 47 patient partners and 56 QIT leaders were conducted in summer 2016 to test the ways in which patient partners affected quality improvement (QI) and gauge respondents' perceptions of the impact of patient partners' contributions. RESULTS: Patient partners influenced QI through three key mechanisms: symbolism, providing feedback (on written material for patients and new policies), and making suggestions (on office communication, educational materials, physical space, and clinical care processes). Almost three quarters of the patient partners believed they had a moderate to very large impact on their QIT's QI efforts. Eight of the 10 QIT leaders reported that patient partners improved patient-centeredness of QI a "moderate amount" to a "great deal" through one of the three key mechanisms. CONCLUSION: Integrating patient partners into ambulatory care QITs was a largely positive experience for patient partners, QIT leaders, and administrators. The changes that patient partners prompted were meaningful and likely improved patients' experience with care. PMID- 29579444 TI - Optimizing Hospitalist-Patient Communication: An Observation Study of Medical Encounter Quality. AB - BACKGROUND: Optimizing patient-hospitalist interactions heightens patient satisfaction, improves patient health outcomes, and improves hospitalist job satisfaction. A study was conducted to recognize hospitalist communication that enhance encounters, identify hospitalist behaviors for improvement interventions, and explore the association of time and gender with communication quality. METHODS: Researchers observed encounters between 36 hospitalists and 206 adult patients. All but 1 of the hospitalists was observed at a 410-bed, general medical and surgical facility in the Midwest. RESULTS: On the adapted Kalamazoo Essential Elements of Communication Checklist (KEECC), hospitalists scored highest on the Builds a Relationship, Shares Information, and Gathers Information dimensions. Participants were seen using multiple, effective verbal and nonverbal techniques to show care and concern, as well as create relational rapport, often while successfully sharing and obtaining clinical information. Hospitalists scored lowest on the Understands the Patient Perspective and Reaches Agreement dimensions. Hospitalists were observed infrequently and inconsistently empathizing with patients and rarely attempting to gain shared understanding and agreement from patients. Significant difference was found in sharing information (t [194] = 2.47; p = 0.01), with male hospitalists (mean [M] = 4.14; standard deviation [SD] = 1.01) more highly rated than female hospitalists (M = 3.78; SD = 0.90). Hospitalist and patient gender match revealed significant difference in sharing information (F [3,192] = 2.60; p = 0.05). Male hospitalists were rated higher interacting with female patients than female hospitalists interacting with male patients. CONCLUSION: Results identify specific hospitalist communication techniques that may ultimately contribute to better-quality medical encounters. Communication interventions are recommended. PMID- 29579445 TI - A Collaborative for Implementation of an Evidence-Based Clinical Pathway for Enhanced Recovery in Colon and Rectal Surgery in an Affiliated Network of Healthcare Organizations. AB - BACKGROUND: In 2015 the Mayo Clinic Care Network (MCCN), in an effort to extend medical knowledge and share these best practices, embarked on an education mission to diffuse the clinical practice redesign involving the practice of colon and rectal surgery at Mayo Clinic (Rochester, Minnesota) to members of the MCCN. They elected to use a collaborative framework in an attempt to transfer knowledge to multiple teams in an efficient and supportive manner. METHODS: Eight MCCN members assembled a multidisciplinary team, which participated in both a didactic learning session delivered by frontline experts, as well as follow-up remote sessions regarding Mayo Clinic's enhanced recovery pathway for colon and rectal surgery. Teams departed the group session with established immediate next steps, communication plans, and an awareness of potential barriers and strategies for mitigation. Monthly coaching calls followed in an effort to help all teams meet their time line and overall goals. Finally, all participants met again after six months to report their clinical outcomes, as well their unique individual organization's successes and barriers encountered. RESULTS: Participating teams felt overwhelmingly that the collaborative program exceeded their expectations and equipped them with the tools to be successful. They also felt that the extended support provided by the Mayo Clinic team was essential, and the collaboration with other members markedly enhanced their experience. Importantly, all teams were able to successfully reduce length of stay, which was the desired main clinical outcome. DISCUSSION: The collaborative format was instrumental in the rapid diffusion and successful implementation of a transformative practice redesign involving colorectal surgical care of patients. PMID- 29579446 TI - The Hidden Cost of Regulation: The Administrative Cost of Reporting Serious Reportable Events. AB - BACKGROUND: More than half of the 50 states (27) and the District of Columbia require reporting of Serous Reportable Events (SREs). The goal is to hold providers accountable and improve patient safety, but there is little information about the administrative cost of this reporting requirement. This study was conducted to identify costs associated with investigating and reporting SREs. METHODS: This qualitative study used case study methods that included interviewing staff and review of data and documents to investigate each SRE occurring at one academic medical center during fiscal year 2013. A framework of tasks and a model to categorize costs was created. Time was summarized and costs were estimated for each SRE. RESULTS: The administrative cost to process 44 SREs was estimated at $353,291, an average cost of $8,029 per SRE, ranging $6,653 for an environmental-related SRE to $21,276 for a device-related SRE. Care management SREs occurred most frequently, costing an average $7,201 per SRE. Surgical SREs, the most expensive on average, cost $9,123 per SRE. Investigation of events accounted for 64.5% of total cost; public reporting, 17.2%; internal reporting, 10.2%; finance and administration, 6.0%; and 2.1%, other. Even with 26 states mandating reporting, the 17.2% incremental cost of public reporting is substantial. CONCLUSION: Policy makers should consider the opportunity costs of these resources, averaging $8,029 per SRE, when mandating reporting. The benefits of public reporting should be collectively reviewed to ensure that the incremental costs in this resource-constrained environment continue to improve patient safety and that trade-offs are acknowledged.

PMID- 29579448 TI - Improving Satisfaction with Pediatric Pain Management by Inviting the Conversation. AB - BACKGROUND: Patient satisfaction with pain management is associated with improved patient adherence to medical management and efficient service utilization. Pediatric pain control is challenging, given the inability to elicit reliable histories, particularly in younger patients. Several studies have suggested that communication surrounding pain management can improve satisfaction, although there are limited data describing structured interventions with measurable outcomes. A quality improvement project was conducted to determine if reliably asking families about pain management was associated with improved patient satisfaction with pain management. METHODS: In an academic pediatric hospital, nurse manager rounds were used to invite a conversation about pain management. The question, "Pain management is very important to us. Has your child's pain been well controlled?" was added to the established standard questions asked during nurse manager rounds. Effectiveness was measured using the preexisting Press Ganey survey question, "How well was your child's pain controlled?" Responses were compared between those patients who were and were not exposed to the rounding question. RESULTS: Data for 1,032 patients were used to establish baseline satisfaction with pain management scores. In the intervention period, 328 patients received nurse manager rounds and 121 did not. The median of the weighted mean patient survey satisfaction scores were baseline, 91.5%; receiving intervention, 94.2%; and not receiving intervention, 90.0%. Patients who received the intervention reported higher satisfaction with pain management than those who did not (p <0.0001). CONCLUSION: Hospitals seeking to improve satisfaction with pain management should encourage health care providers to reliably discuss pain control with pediatric patients.

PMID- 29579452 TI - Research Techniques Made Simple: Two-Photon Intravital Imaging of the Skin. AB - Over the last few years, intravital two-photon microscopy has matured into a powerful technology helping basic and clinical researchers obtain quantifiable details of complex biological mechanisms in live and intact tissues. Two-photon microscopy provides high spatial and temporal resolution in vivo with little phototoxicity that is unattainable by other optical tools like confocal microscopy. Using ultrashort laser pulses, two-photon microscopy allows the visualization of molecules, cells, and extracellular structures up to depths of 1 mm within tissues. Consequently, real-time imaging of the individual skin layers under both physiological and pathological conditions has revolutionized our understanding of cutaneous homeostasis, immunity, and tumor biology. This review provides an overview to two-photon microscopy of the skin by covering the basic concepts and current applications in diverse preclinical and clinical settings. PMID- 29579453 TI - Survival of Second-Line Biologics in Psoriasis: The British BADBIR Registry Data Informs Daily Practice. AB - Psoriasis is one of the most chronic diseases in dermatology. Only a small percentage of patients ever experience relapse-free survival. The constant presence of plaques and comorbidities that affect the cardiovascular system, joints, and other organs greatly impair patients' quality of life. In addition, the life expectancy of psoriatic patients is shortened by several years. Hence, long-term and ideally systemic treatment with minimal adverse effects may be warranted.

It is especially interesting to study gentamicin 1B because it may be more efficacious than other gentamicin components. Topical gentamicin has an acceptable safety profile, although prospective tracking of antibiotic resistance is warranted. PMID- 29579456 TI - Targeting the Plasticity of Psoriasis. AB - Psoriasis is a common inflammatory condition found in 1-2% of the population. The greatest advances in psoriasis treatment have occurred in patients with severe psoriasis, moving from systemic small molecules including methotrexate, cyclosporine, and retinoids to targeted agents against psoriasis-associated cytokines, such as TNF-alpha, IL-12, IL-23, and IL-17. Although the new biologics do not have the same adverse effects as the systemic drugs, they do predispose to systemic infections (and perhaps cancer), and they are extremely expensive. The focus on biologic therapies has been accompanied by a relative neglect of small molecules, which can be used either topically or systemically. No small molecule has been able to compete significantly with topical glucocorticoids, the mainstay of treatment for mild to moderate psoriasis for more than half a century. PMID- 29579458 TI - Addendum. PMID- 29579457 TI - A Modeling Conundrum: Murine Models for Cutaneous Wound Healing. AB - The complexity of the cutaneous wound healing process and its impairment in disease states, combined with the urgent clinical need for new therapies demand well-defined preclinical models that facilitate translation of research findings to clinical use. Many murine wound models are well suited for studying mechanisms of various aspects of wound healing, but they have shown limited utility for translating research findings to human conditions, thereby impeding therapeutic developments. Ansell et al. underscore the need for standardization of preclinical murine models by showing the impact of duration of diabetes, animal sex, and assessment methods on healing outcomes in the streptozotocin-induced diabetes mellitus rat model. Recognizing and understanding the limitations and advantages of preclinical murine wound models will facilitate more effective translation of experimental results to improved treatment of human chronic wounds.

Although development of extrahepatic collateral blood supply is well known, its importance in the presentation of rupture of liver tumors may be underrecognized. Findings that suggest bleeding from extrahepatic arteries include a discrepancy in the pattern of extravasation on computed tomography vs hepatic angiography and a lack of stabilization of vital signs after embolization of hepatic arteries. To achieve successful hemostasis in embolization, the potential involvement of such extrahepatic arteries should be accurately recognized, suggestive imaging findings considered, and the occult vessels selected and embolized.

We describe a simple, safe, and effective technique of paravertebral catheter insertion by the operative surgeon after a retroperitoneal abdominal aortic aneurysm repair. Once the aneurysm repair is complete, an extrapleural plane between the parietal pleura and the twelfth rib is created through blunt dissection. A catheter is advanced into the space percutaneously under direct vision, and a continuous infusion of local anesthetic is administered. Paravertebral catheters typically remain in place for 3 to 5 days and provide excellent postoperative non-narcotic analgesia. PMID- 29579474 TI - MIPS cost measures for 2018.

AB - The convenient preparation of iminopentitol derivatives, based on a 1,4-dideoxy 1,4-imino-l-arabinitol scaffold carrying beta-phosphono(difluoromethyl) or beta phosphonomethyl appendages, as Galf-1P mimics, is reported. The compounds were tested for their ability to inhibit GlfT2, a vital galactofuranosyltransferase involved in the cell wall biosynthesis of mycobacteria. Interestingly, the Galf 1P mimics lacking a fluorine atom (7 and 8) were very poor inhibitors, showing less than 20% inhibition of GlfT2, whereas compounds 2 and 3, which contains a difluoromethylenephosphonate moiety were more potent inhibitors. Compound 3 that is fully deprotected was the most potent showing a significant IC50 value (0.9 mm), despite the absence of the diphosphate linkage present in the parent sugar nucleotide. This study paves the way to the synthesis of more complex beta phosphonomethyl-imino-l-arabinitol derivatives as simplified mimics of UDP-alpha d-Galf. PMID- 29579478 TI - Surgical resection versus systemic therapy for breast cancer liver metastases: Results of a European case matched comparison. AB - BACKGROUND: Resection of breast cancer liver metastases (BCLM) combined with systemic treatment is increasingly accepted but not offered as therapeutic option. New evidence of the additional value of surgery in these patients is scarce while prognoses without surgery remains poor. PATIENTS AND METHODS: For this case matched analysis, all nationally registered patients with BCLM confined to the liver in the Netherlands (systemic group; N = 523) were selected and compared with patients who received systemic treatment and underwent hepatectomy (resection group; N = 139) at a hepatobiliary centre in France. Matching was based on age, decade when diagnosed, interval to metastases, maximum metastases size, single or multiple tumours, chemotherapy, hormonal or targeted therapy after diagnosis. Based on published guidelines, palliative systemic treatment strategies are similar in both European countries. RESULTS: Between 1983 and 2013, 3894 patients were screened for inclusion. Overall median follow-up was 80 months (95% CI 70-90 months). The median, 3- and 5-year overall survival of the whole population was 19 months, 29% and 19%, respectively. The resection and systemic group had median survival of 73 vs. 13 months (P < 0.001), respectively. Three and 5-year survival was 18% and 10% for the systemic group and 75% and 54% for the resection group, respectively. After matching, the resection group had a median overall survival of 82 months with a 3- and 5-year overall survival of 81% and 69%, respectively, compared with a median overall survival of 31 months in the systemic group with a 3- and 5-year overall survival of 32% and 24%, respectively (HR 0.28, 95% CI 0.15-0.52; P < 0.001). CONCLUSIONS: For patients with BCLM, liver resection combined with systemic treatment results in improved overall survival compared to systemic treatment alone. Liver resection should be considered in selected cases. PMID- 29579479 TI - Editorial: Special issue on advances in biomedical image processing. PMID- 29579480 TI - Can white-rot fungi be a real wastewater treatment alternative for organic micropollutants removal? A review. AB - Micropollutants are a diverse group of compounds that are detected at trace concentrations and may have a negative effect on the environment and/or human health. Most of them are unregulated contaminants, although they have raised a concern in the scientific and global community and future regulation might be written in the near future. Several approaches have been tested to remove micropollutants from wastewater streams. In this manuscript, a focus is placed in reactor biological treatments that use white-rot fungi. A critical review of white-rot fungal-based technologies for micropollutant removal from wastewater has been conducted, several capabilities and limitations of such approaches have been identified and a range of solutions to overcome most of the limitations have been reviewed and/or proposed. Overall, this review argues that white-rot fungal reactors could be an efficient technology to remove micropollutants from specific wastewater streams. PMID- 29579481 TI - Understanding and alleviating maternal postpartum distress: Perspectives from first-time mothers in Australia. AB - BACKGROUND: Numerous factors have been shown to cause (or alleviate) maternal psychological distress in the early postpartum period, and a variety of interventions have been developed with the goal of preventing and/or managing such distress. However, only a few studies have explored new mothers' perspectives on the sources of their distress in the first six months' postpartum alongside the researchers' recommendations for interventions to address those sources. OBJECTIVES: The aim of this work was to (a) identify factors associated with normative psychological distress in the first 6-months' postpartum by healthy Australian first-time mothers, and (b) outline practical methods-rooted in those factors-deemed to be effective for preventing maternal psychological distress. METHOD: Semi-structured interviews with 32 first-time mothers and thematic content analysis. RESULTS: Factors associated with maternal psychological distress emerged in relation to cognitive, behavioural, baby, and social factors. Mothers also indicated that interventions targeting reductions in psychological distress should include education-for mothers and significant others-prior to the postpartum period. These interventions should be delivered by credible information sources (e.g. other mothers, child-health nurses) and should focus on confidence-enhancement and social support provision. CONCLUSION: As well as reinforcing evidence regarding common postpartum stressors, this study revealed novel insight into issues associated with normative psychological distress for new mothers (e.g., self-compassion). Perhaps most significant was that mothers also identified a range of clear practical strategies for community based intervention designs that target psychological distress. As a result, these findings provide guidelines for interventions aimed at reducing psychological distress in the early postpartum period for Australian mothers. PMID- 29579482 TI - Effect of recorded maternal voice, breast milk odor, and incubator cover on pain and comfort during peripheral cannulation in preterm infants. AB - PURPOSE: This study was conducted to assess the effect of recorded maternal voice, breast milk odor, and incubator cover on the pain and comfort of preterm infants during peripheral cannulation. METHODS: This study was a randomized controlled trial. The sample of the study included 136 preterm infants who met the case selection criteria. The infants were randomly assigned to different groups. DATA COLLECTION TOOL: In the study, a recorded maternal voice was played to the maternal voice group. The breast milk odor group was exposed to the odor of breast milk. The incubator cover group was covered by using an incubator cover before, during, and after the peripheral cannulation procedure on the infants in the experimental group. RESULT: While no difference was observed between the groups before the peripheral cannulation procedure in terms of the total Premature Infant Pain Profile (PIPP) scores, a significant difference existed between the PIPP scores during and after the procedure. This difference was due to the incubator cover group. CONCLUSION: Breast milk odor, recorded maternal voice, and incubator cover in preterm infants are recommended as simple, safe, and supportive stimuli that facilitate positive effects during painful procedures. PMID- 29579483 TI - Deliberate practice and nurse competence. AB - BACKGROUND: Increasing demand for accountability in health care requires that we understand how nurses continually increase their expertise. Development of expertise has been linked to deliberate practice in many domains but little is known about how deliberate practice impacts the expertise of registered nurses. OBJECTIVES: Evaluate the relationships among experience, education, deliberate practice, and competence as an empirical referent of expertise, and to identify which of the independent variables makes the highest contribution to competence. METHODS: Cross-sectional, descriptive, correlational study design was used. A purposive sample of RNs from one large, Midwestern teaching hospital was surveyed. RESULTS: After taking into consideration demographic variables, education and experience, deliberate practice made the greatest contribution to competence. No significant relationship was found between years of experience or education and competence. CONCLUSION: This study provides empirical evidence for the relationship of deliberate practice to competence, a promising concept for explaining the development of skill acquisition in nursing. PMID- 29579484 TI - Patient-controlled oral analgesia for acute abdominal pain: A before-and-after intervention study on pain intensity and use of analgesics. AB - AIM: To compare the use of patient-controlled oral analgesia with nurse controlled analgesia for patients admitted to hospital with acute abdominal pain. The primary outcome measure was pain intensity. The secondary outcome measures were the use of analgesics and antiemetics. BACKGROUND: Inadequate pain management of patients with acute abdominal pain can occur during hospital admission. Unrelieved acute pain can result in chronic pain, stroke, bleeding and myocardial ischemia. METHODS: A before-and-after intervention study was conducted in an emergency department and a surgical department with three subunits. Data were collected from medical charts and analyzed using chi-squared and Kruskal Wallis tests. RESULTS: A total of 170 patients were included. The median pain intensity score, using the numeric ranking scale, was 2.5 and 2 on Day 2 (p = 0.10), 2 and 2 on Day 3 (p = 0,40), 2.5 and 0 on Day 4 (p = 0.10), 2 and 0 on Day 5 (p = 0.045) in the control and intervention group, respectively. The percentage of patients receiving analgesics was 93 and 86 on Day 2 (p = 0.20), 91 and 75 on Day 3 (p = 0.02), 89 and 67 on Day 4 (p = 0.009) and 80 and 63 on Day 5 (p = 0.39). The use of antiemetics was similar in the two groups. CONCLUSION: Patient controlled oral analgesia significantly reduced the numerical ranking pain scale score on Day 5 and the consumption of analgesics on Days 3 and 4 after hospital admission. Patient-controlled oral analgesia is feasible as pain management for patients, but only with minor impact on experienced pain intensity and use of analgesics. PMID- 29579485 TI - Nurses, age, job demands and physical activity at work and at leisure: A cross sectional study. AB - BACKGROUND: The nursing workforce is ageing and increased age and demands at work, can impact on physical activity levels in the workplace and at leisure. Research has shown that work physical activity, without activity at leisure, is insufficient to prolong well-being. This study investigated the physical activity levels of a sample of nurses and aimed to determine if age and job demands are associated with engaging in recommended physical activity levels at work and at leisure. METHODS: A cross-sectional study was conducted with data collected during 2016. Two-hundred and ten nurses participated in the study. Two validated instruments were used: the Copenhagen Psychosocial Questionnaire (quantitative and cognitive demands) and the International Physical Activity Questionnaire. RESULTS: Older nurses (>=40-years) were significantly less likely to report engaging in recommended physical activity levels at work than younger nurses [OR 0.47, 95% CI (0.25-0.88) p = 0.02]. Nurses with high quantitative demands were over twice as likely to engage in recommended levels of physical activity at work and at leisure. Engaging in recommended levels of physical activity at work was not associated with leisure-time physical activity reports. CONCLUSION: Initiatives need to be put in place to ensure older nurses can fulfil their nursing role within their capabilities. These could include offering personal physical activity education to both on and off-duty nurses. Assessment of ability and patient acuity may be necessary. PMID- 29579486 TI - Incidence and risk factors of workplace violence against nurses in a Chinese top level teaching hospital: A cross-sectional study. AB - PURPOSE: To investigate the incidence of workplace violence involving nurses and to identify related risk factors in a high-quality Chinese teaching hospital. METHODS: A cross-sectional study design was used. The final sample comprised responses from 1831 registered nurses collected with a whole-hospital survey from June 1 to June 15, 2016. The demographic characteristics of the nurses who had experienced any form of violence were collected, and logistic regression analysis was applied to evaluate the risk factors for nurses related to workplace violence. RESULTS: Out of the total number of nurses surveyed, 904 (49.4%) nurses reported having experienced any type of violence in the past year. The frequencies of exposure to physical and non-physical violence were 6.3% (116) and 49.0% (897), respectively. All the incidence rates of violence were lower than those of other studies based on regional hospitals in China and were at the same level found in developed countries and districts. Binary logistic regression analysis revealed that nurses at levels 2 to 4 and female nurses in clinical departments were the most vulnerable to non-physical violence. For physical violence, the two independent risk factors were working in an emergency department and having 6-10 years of work experience. CONCLUSIONS: Workplace violence directly threatens nurses from high-quality Chinese teaching hospitals. However, the incidence of WPV against nurses in this teaching hospital was better than that in regional hospitals. This study also provides reference material to identify areas where nurses encounter relatively high levels of workplace violence in high-quality Chinese teaching hospitals. PMID- 29579487 TI - Factors affecting the delivery of healthcare on a humanitarian operation in West Africa: A qualitative study. AB - INTRODUCTION: Medical personnel in the UK Armed Forces are highly trained to deploy in support of military operations that assist humanitarian, peacekeeping, counter-terrorism and environmental catastrophes anywhere in the world. Such environments are often austere and successful outcomes demand an individual is highly resilient and able to adapt quickly to any situation. This qualitative study aimed to determine the factors that affect healthcare delivery on such missions by capturing the personal experiences of the first military personnel deployed on a humanitarian operation in support of the Ebola outbreak in West Africa between October 2014 and January 2015. METHODS: A grounded theory methodology was utilised to probe the personal accounts of these experiences. Semi-structured interviews were conducted on 14 multi-disciplinary personnel 3-6 months following their return to the UK and were transcribed verbatim. Data were analysed and a framework generated that had been further refined by discussion with military personnel independent of the study but with the contextual understanding and experience of this particular deployment. FINDINGS: The resultant theoretical framework was underpinned by participants framing their experience by "just getting on with it". Stressors such as a poor flow of information, a fear of the unknown, strict patient admission criteria, environmental constraints and transcultural boundaries to care were mitigated by strong leadership, teamwork, peer support and the positive impact of having made a difference. CONCLUSION: Collective pre-deployment training generated competence, confidence and team cohesiveness providing a firm foundation for coping with the challenges of this humanitarian mission, which continued to be strengthened throughout the deployment. These factors helped to build personnel's resilience to the stressors associated with the mission and may help to protect their mental health outcomes in the longer-term. PMID- 29579488 TI - Relationships between public health nurse-delivered physical activity interventions and client physical activity behavior. AB - AIM: The purpose of this study was to identify physical activity interventions delivered by public health nurses (PHNs) and examine their association with physical activity behavior change among adult clients. BACKGROUND: Physical activity is a public health priority, yet little is known about nurse-delivered physical activity interventions in day-to-day practice or their outcomes. METHODS: This quantitative retrospective evaluation examined de-identified electronic-health-record data. Adult clients with at least two Omaha System Physical activity Knowledge, Behavior, and Status (KBS) ratings documented by PHNs between October 2010-June 2016 (N=419) were included. Omaha System baseline and follow-up Physical activity KBS ratings, interventions, and demographics were examined. RESULTS: Younger clients typically receiving maternal-child/family services were more likely to receive interventions than older clients (p<0.001). A total of 2869 Physical activity interventions were documented among 197 clients. Most were from categories of Teaching, Guidance, Counseling (n=1639) or Surveillance (n=1183). Few were Case Management (n=46). Hierarchical regression modeling explained 15.4% of the variance for change in Physical activity Behavior rating with significant influence from intervention dose (p=0.03) and change in Physical activity Knowledge (p<0.001). CONCLUSION: This study identified and described physical activity interventions delivered by PHNs. Implementation of department-wide policy requiring documentation of Physical activity assessment for all clients enabled the evaluation. A higher dose of physical activity interventions and increased Physical activity knowledge were associated with increased Physical activity Behavior. More research is needed to identify factors influencing who receives interventions and how interventions are selected. PMID- 29579489 TI - First-time fathers' health status during the perinatal period. AB - BACKGROUND: For first-time fathers, the perinatal period is a critical period of stress and imbalance. Marital intimacy and social support may affect their stress and health status while they change their roles. AIM: This study was to explore the changes of and correlations among marital intimacy, social support, and health status and predictors of first-time fathers' health status during the perinatal period. METHODS: With a repeated measures study design, a total of 217 first-time fathers whose spouses were in the third trimester of pregnancy were recruited for the study. The Chinese Health Questionnaire, Marital Intimacy Scale, and Social Support Scale were employed to collect data at a medical center in the 36th week of pregnancy and the 1st and 4th weeks after childbirth. RESULTS: The levels of marital intimacy and social support of first-time fathers during the perinatal period increased significantly with time. Meanwhile, the period of the first week after childbirth was a predictor of first-time father's health status. CONCLUSIONS: This study only tracked the first-time fathers' health status in the 36th week of pregnancy and the 1st and 4th weeks after childbirth. Future studies could track them until one year after childbirth in order to explore the impact of the perinatal period on the couples and their babies. During the perinatal period, health care providers shall assess and provide needed interventions to first-time fathers as soon as possible to facilitate the first-time fathers to get ready for the role transition and to promote their health status. PMID- 29579490 TI - Evaluating a psychosocial intervention for men with prostate cancer and their partners: Outcomes and lessons learned from a randomized controlled trial. AB - AIM: This study evaluated the process and outcome of a psychosocial intervention for men with prostate cancer and their partners. As more men survive prostate cancer, they and their partners need help and support to help them cope with the physical and psychosocial effects of the disease and treatment. There is a lack of psychosocial interventions for men with prostate cancer and their partners. METHODS: A randomized controlled trial was conducted with 34 participants to measure the effects of the intervention on selected psychosocial outcomes, post intervention and at one month' follow-up. The nine-week program (CONNECT) consisted of three group and two telephone sessions. It focused on symptom management, sexual dysfunction, uncertainty management, positive thinking and couple communication. The outcomes, measured by validated tools were: self efficacy, quality of life, symptom distress, communication, uncertainty and illness benefits. RESULTS: The men in the intervention group did better on two outcomes (communication and support) than controls. Partners in the intervention group did better than controls on most outcomes. Less participants than expected participated in the trial. The reasons for non-participation included partners not wishing to participate, men not interested in group work, and not understanding the core purpose of the intervention. The cost of training facilitators and for delivering the intervention appeared to be low. CONCLUSION: The knowledge generated from this study will be beneficial for all those grappling with the challenges of developing, implementing and evaluating complex psychosocial interventions. This study has also highlighted the difficulties in recruiting men and their partners in clinical trials. PMID- 29579491 TI - Evaluation of an assessment instrument for a sexual health curriculum for nurses and midwifery students in Tanzania: The sexual health education for professionals scale (SHEPS). AB - We assessed the structure and content of a new scale, the SHEPS, to assess change in sexual health confidence, knowledge and attitudes in nursing and midwifery students following an intervention (a 2-day standardized workshop on sexual health). Students were 78 Tanzanian nursing and midwifery students attending a University of Health Sciences, who were assessed immediately before and after the workshop on matched pre- and post-workshop questionnaires. Data confirmed significant changed pre- and post-test on knowledge and confidence on topics taught in the workshop, with the effect also extending to some topics not or minimally covered, suggesting that there was a general increase in confidence and a perception of increased knowledge following the workshop. There was power to detect differences even with a moderate sized matched sample. Correlations between knowledge and confidence on the same content items were between 0.52 and 0.63, suggesting that respondents could clearly distinguish between knowledge and confidence. There were no significant differences pre- and post-test on several controversial cultural and religious attitudes including on abortion and non vaginal penetrative sex. Alpha coefficients were 0.93 for pre-test and 0.90 for post-test. This field test demonstrates the preliminary appropriateness of the SHEPS as a tool for evaluating sexual health interventions in health care workers. PMID- 29579492 TI - Palliative sedation and moral distress: A qualitative study of nurses. AB - BACKGROUND: Clinical nursing practice may involve moral distress, which has been reported to occur frequently when nurses care for dying patients. Palliative sedation is a practice that is used to alleviate unbearable and refractory suffering in the last phase of life and has been linked to distress in nurses. AIM: The aim of this study was to explore nurses' reports on the practice of palliative sedation focusing on their experiences with pressure, dilemmas and morally distressing situations. METHODS: In-depth interviews with 36 nurses working in hospital, nursing home or primary care. RESULTS: Several nurses described situations in which they felt that administration of palliative sedation was in the patient's best interest, but where they were constrained from taking action. Nurses also reported on situations where they experienced pressure to be actively involved in the provision of palliative sedation, while they felt this was not in the patient's best interest. The latter situation related to (1) starting palliative sedation when the nurse felt not all options to relieve suffering had been explored yet; (2) family requesting an increase of the sedation level where the nurse felt that this may involve unjustified hastening of death; (3) a decision by the physician to start palliative sedation where the patient had previously expressed an explicit wish for euthanasia. CONCLUSIONS: Nurses experienced moral distress in situations where they were not able to act in what they believed is the patient's best interest. Situations involving moral distress require nurses to be well informed and able to adequately communicate with suffering patients, distressed family and physicians. PMID- 29579493 TI - Missed Nursing Care: Research on Interventions? PMID- 29579494 TI - Evaluation of bedside shift report: A research and evidence-based practice initiative. AB - This evaluation of bedside shift report describes the process of involving clinical nurses in evidence-based practice (EBP) and research at an academic medical center by using existing structures and resources. Nurse involvement and study findings are described from idea inception to asking the clinical question, searching and synthesizing literature, collecting and analyzing data, interpreting results, and deriving conclusions. Study findings and conclusions demonstrate that nurses' active participation in a clinical relevant project promotes implementation and integration of EBP and research in the practice setting. PMID- 29579495 TI - Canadian hospital nurses' roles in communication and decision-making about goals of care: An interpretive description of critical incidents. AB - BACKGROUND: Nurses in acute medical units are uniquely positioned to support goals of care communication. Further understanding of nurse and physician perceptions about hospital nurses' actual and possible roles was required to improve goals of care communication. OBJECTIVE: To critically examine nurse and physician perceptions of the nurse's role in communication with seriously ill patients and their families. DESIGN: We focus on the qualitative component of a mixed method study. We employed an interpretive descriptive approach informed by Flanagan's critical incident technique. SETTINGS: Participants were recruited from the acute medical units at three tertiary care hospitals in three Canadian provinces. PARTICIPANTS: Thirty participants provided interviews (10 from each site): 12 nurses, 9 staff physicians and 9 medical resident physicians. METHODS: Participants' described "critical incidents" they considered as "excellent" or "poor" or "usual" practice. Interviews, were audiotaped and transcribed. Team based analysis used constant comparison and triangulation to identify healthcare team members' roles in goals of care communication. RESULTS: We identified two major themes from 120 critical incidents: 1) the ambiguous nature of the nurse's role in formal, physician-led, decision-making communication, and 2) embedded in care serious illness communication. Physicians understood nurses' supportive role in relation to their own communication practices that culminated in decisions about care; nurses' reported their roles were determined by unit routines, physician practices and preferences, and their self-confidence in supporting decision-making. Nurses described their unique role in facilitating informal and spontaneous communication with patients and families that was critical background work to physician-led goals of care communication. CONCLUSIONS: Nurses and physicians had different understandings, practices and beliefs about goals of care communication The value of nurses embedded in care work is key to supporting the interprofessional team's work during formal goals of care communication. PMID- 29579496 TI - Effects of bathing interval on skin condition and axillary bacterial colonization in preterm infants. AB - AIM: The objective of this study was to evaluate the effects of preterm infant bathing periods on skin condition and axillary skin colonization. BACKGROUND: Reducing the frequency of bathing in preterm infants is beneficial in reducing the risk of hypothermia and exposure to stress from frequent nursing contacts. METHODS: The subjects of this study were observed at The V hospital at the C University in South Korea between December 2012 and August 2013. A total of 32 preterm infants were included and were randomly assigned to two different bathing intervals; every four days (n=16) and the other every two days (n=16) bathing groups. A neonatal skin conditions were assessed on a daily basis, whereas, axillary skin colonization was measured every eight days before bathing. Data was analyzed via the SPSS program with a non-inferiority test, t-test, chi-square test, Fisher's exact test, and paired t-test. RESULTS: Mean differences of skin condition between the four-day bathing and two-day bathing groups were 0.065 and the 97.5% one-sided confidence limit was 0.196 (less than the non-inferiority margin, 0.3). There were no statistically significant differences in skin condition and axillary skin colonization between the two groups (p>0.05). CONCLUSION: The interval of bathing for preterm infants can be changed from every two days to every four days without increasing the incidence of skin condition problems or axillary skin colonization. Less-frequent bathing may decrease the chance of physiological instability caused by the caring process, while providing them with a better environment for growth and development. PMID- 29579497 TI - The perceptions of patient safety culture: A difference between physicians and nurses in Taiwan. AB - AIMS: In order to pursue a better patient safety culture and provide a superior medical service for patients, this study aims to respectively investigate the perceptions of patient safety from the viewpoints of physicians and nurses in Taiwan. BACKGROUND: Little knowledge has clearly identified the difference of perceptions between physicians and nurses in patient safety culture. Understanding physicians and nurses' attitudes toward patient safety is a critical issue for healthcare organizations to improve medical quality. METHODS: Confirmatory factor analysis (CFA) is used to verify the structure of data (e.g. reliability and validity), and Pearson's correlation analysis is conducted to demonstrate the relationships among seven patient safety culture dimensions. RESULTS: Research results illustrate that more teamwork is exhibited among team members, the more safety of a patient is committed. Perceptions of management and emotional exhaustion are important components that contribute to a better patient safety. More importantly, working conditions and stress recognition are found to be negatively related from the perceptions of nurses. Compared to physicians, nurses reported higher stress and challenges which result from multi-task working conditions in the hospital. CONCLUSIONS: This study focused on the contribution of a better patient safety culture from different viewpoints of physicians and nurses for healthcare organizations in Taiwan. A different attitudes toward patient safety is found between physicians and nurses. The results enable the hospital management to realize and design appropriate implications for hospital staffs to establish a better patient safety culture. PMID- 29579498 TI - Factors associated with psychological distress amongst outpatient chemotherapy patients: An analysis of depression, anxiety and stress using the DASS-21. AB - AIM: This study sought to identify clinical, demographic and service-related factors associated with psychological distress amongst outpatient chemotherapy patients. BACKGROUND: Distress in cancer patients leads to increased risk of psychological comorbidity, contributing to sub-optimal treatment adherence and potentially leading to poorer health outcomes. Screening and recognition of distress and risk factors is an important aspect of holistic care within a multidisciplinary team environment. METHODS: Data were obtained via survey and chart review of ambulatory chemotherapy patients at three public tertiary referral hospitals in Perth, Western Australia. The DASS-21 was used to screen for psychological distress. Regression analyses were used to assess the relationship between distress and a range of cancer, socioeconomic and treatment factors. RESULTS: Patients with a Karnofsky Performance Score<=80 (OR 3.8, 95% CI [1.7, 78.7]) and average waiting time (between oncology outpatient appointment and commencement of chemotherapy infusion) >60min (OR 2.4, 95% CI [1.04, 5.5]) were at increased risk of moderate-severe distress. Patients with a household income between $AU 50-75,000 p.a. had a lower risk of distress compared to <$25,000 p.a. (OR 0.05, 95% CI [0.01, 0.52]). On sub-scale analysis, depression and anxiety contributed more to overall distress than the stress subscales. CONCLUSIONS: Performance status, waiting times and household income were key predictors of distress. Findings could assist clinicians to identify higher-risk population subsets that could benefit from targeted screening and additional psychological and social work support. Findings could also assist administrators to consider the contribution of modifiable factors such as waiting times to patient distress. PMID- 29579499 TI - Using narrative intervention for HPV vaccine behavior change among Khmer mothers and daughters: A pilot RCT to examine feasibility, acceptability, and preliminary effectiveness. AB - PURPOSE: To develop a theory-guided culturally grounded narrative intervention to promote HPV vaccination behavior and examine the feasibility, acceptability, and preliminary effectiveness of the intervention among dyads of Cambodian American mothers and daughters. METHOD: The principles of community-based participatory research guided the development and evaluation and involved two phases: Phase 1: Development of storytelling narrative intervention videos which focused on a series of HPV vaccination-related messages and which integrated the narrative theory with the revised network episode model (rNEM); Phase 2: conducting the pilot RCT with 19 dyads of Khmer mothers and daughters aged from 14 to 17years to examine the feasibility and acceptability of the study. FINDINGS: Recruitment was completed in 7months with an overall retention of 84%. The acceptability of the intervention was high, as reflected by the number of positive comments on the narrative video. Preliminary data indicate that vaccine uptake at one-month follow-up was the same (2 vs. 2) between intervention and control groups. However, daughters in the narrative intervention group reported higher intention to receive HPV vaccination within one month compared to the control group (4 vs. 1). CONCLUSION: All the procedures to inform a full RCT were examined, including identification of eligible participants, recruitment, randomization, intervention adherence, and short-term follow-up. The positive preliminary outcomes and feedback support the feasibility and potential effectiveness of the theory-guided narrative intervention. PMID- 29579500 TI - Nursing duties and accreditation standards and their impacts: The nursing perspective. AB - BACKGROUND: Medical advances and increasingly complex patients presenting to the Emergency Department (ED) make nursing challenging. Gaining new knowledge and skills is a perpetual requirement. New quality initiatives to improve patient safety and care are being constantly introduced and create significant work and time pressures for healthcare providers involved. STUDY QUESTION: Do ED nurses support the introduction of new quality standards, in addition to their current heavy workload? STUDY DESIGN: A cross-sectional survey. METHODS: All ED nurses in the Edmonton zone were invited to complete a survey on nursing beliefs regarding various accreditation standards and their impacts. The survey was developed iteratively, involving study investigators, the Health Authority Management Team, and Nursing Managers. Response options included a 7-point Likert scale of agreement. Median ratings and interquartile ranges were determined for each survey statement. RESULTS: A total of 433/1241 (34.9%) surveys were completed. Respondents were RNs (91.4%), female (88.9%), with 0-5years ED experience (43.7%). Overall, respondents 'agreed' or 'strongly agreed' with the statements, indicating favourable attitudes towards Accreditation Canada standards and other quality initiatives. They were neutral towards universal domestic violence screening, and the differentiation between a Best Possible Medication History and medication reconciliation. CONCLUSIONS: Despite their heavy workload, nurses strongly agreed on the importance of medication reconciliation, falls risk, and skin care, but felt that improved documentation forms could support efficiency. This nursing perspective is valuable in informing attempts to standardize and simplify documentation, including the design and implementation of a provincial clinical information system. PMID- 29579501 TI - Experiences of women and men living with urinary incontinence: A phenomenological study. AB - AIMS: To explore and understand, from a gender-based perspective, the quality-of life experiences of men and women who suffer from urinary incontinence. BACKGROUND: Urinary incontinence (UI) is a major health problem with significant social, psychological, occupational, sexual and economic effects leading to a substantial decrease in quality of life. Although this condition is increasingly frequent in men, research has tended to focus on women, adopting a quantitative approach. DESIGN: The data were examined using interpretive phenomenological analysis (IPA). METHODS: The data were collected through a semi-structured interview conducted between January and June 2016. An inductive discourse content analysis was performed in three stages: preparation, organization and report. Participants were recruited until data saturation was achieved. FINDINGS: A sample of 33 participants was recruited: 17 women and 16 men. Gender-specific features were found. Six categories emerged: (i) normalization of incontinence; (ii) verbalization of the problem; (iii) social isolation; (iv)experienced feelings and emotions; (v) impact on daily routine; (vi) self-care strategies to address the problem in the most suitable way. CONCLUSION: Urinary incontinence has a negative effect on the quality of life of men and women. However, there are gender differences as to how this phenomenon is experienced, particularly with regard to its psychological and social dimensions. A comprehensive, targeted assessment of the needs of these men and women is required on the part of professional nurses. PMID- 29579502 TI - Surgical weight loss as a life-changing transition: The impact of interpersonal relationships on post bariatric women. AB - : Surgical Weight Loss as A Life-changing Transition: The Impact of Interpersonal Relationships on Post-Bariatric Women BACKGROUND: Although women account for 80% of patients having bariatric surgery (BS), the complex psychosocial mechanisms that accompany this transformation process have not been well established. PURPOSE: The purpose of this study is to explore the lived experience of women transitioning in their interpersonal relationships post BS. METHODS: A semi structured interview with four questions was used. Six women, from six to 12 months post BS, were interviewed. The interviews were recorded, transcribed and analyzed using thematic analysis. MAIN FINDINGS: By seeking support systems prior to undergoing BS, adequate social support was received during their recovery period. Attending bariatric support group meetings and using social media were significant to these women's satisfactory recovery. Relationship adjustments were sometimes needed, but overall these women established fulfilling social lives. Within the first year post bariatric surgery, women began to gain emotional strength and inspire others to lose weight as well. CONCLUSIONS: By inquiring about the psychosocial concerns of women who have undergone BS, healthcare providers can provide a more practical wellness plan. PMID- 29579503 TI - Effect of peripheral IV based blood collection on catheter dwell time, blood collection, and patient response. AB - AIM: To evaluate the effect of daily PIV-based phlebotomy using the PIVO device on PIVC dwell times and replacement rates, as well as the reliability of blood sample collection, and patient response to this method of blood collection. BACKGROUND: Blood draws which are also known as phlebotomy for laboratory analyses are one of the most common experiences for hospitalized patients. When performed by venipuncture, they are often associated with pain and anxiety for patients. Most hospitals avoid phlebotomy from peripheral IV catheters due to sample hemolysis, sample dilution by fluids in PIVC line or infused medications, PIVC dislodgement or infiltration, and increased rates of phlebitis. METHODS: A prospective, randomized- controlled study of 160 GI surgery patients was enrolled. Patients were randomized to either control evaluation of PIVC dwell or to receive daily PIVO blood collections in addition to evaluation of PIVC dwell. RESULTS: Daily PIVO blood collections did not negatively affect PIVC dwell or replacement rates. Overall 81% of blood collection attempts were successful and the likelihood of success was strongly associated with PIVC condition. Patients reported 0.7/10 pain for PIVO blood collection on a 0-10 pain scale and a 9.1/10 preference for PIVO on a 0 (strongly prefer needle) to 10 (strongly prefer PIVO) preference scale. Results suggest that use of a PIV based blood collection was a reliable and valid approach and was superior to routine phlebotomy in self reported responses from patients. PMID- 29579504 TI - Mixed methods evaluation of a quality improvement and audit tool for nurse-to nurse bedside clinical handover in ward settings. AB - BACKGROUND: Nurse bedside handover quality is influenced by complex interactions related to the content, processes used and the work environment. Audit tools are seldom tested in 'real' settings. OBJECTIVE: Examine the reliability, validity and usability of a quality improvement tool for audit of nurse bedside handover. DESIGN: Naturalistic, descriptive, mixed-methods. SETTING: Six inpatient wards at a single large not-for-profit private health service in Victoria, Australia. PARTICIPANTS: Five nurse experts and 104 nurses involved in 199 change-of-shift bedside handovers. METHODS: A focus group with experts and pilot test were used to examine content and face validity, and usability of the handover audit tool. The tool was examined for inter-rater reliability and usability using observation audits of handovers across six wards. Data were collected in 2013-2014. RESULTS: Two independent observers for 72 audits demonstrated acceptable inter-observer agreement for 27 (77%) items. Reliability was weak for items examining the handover environment. Seventeen items were not observed reflecting gaps in practices. Across 199 observation audits, gaps in nurse bedside handover practice most often related to process and environment, rather than content items. Usability was impacted by high observer burden, familiarity and non-specific illustrative behaviours. CONCLUSION: The reliability and validity of most items to audit handover content was acceptable. Gaps in practices for process and environment items were identified. Context specific exemplars and reducing the items used at each handover audit can enhance usability. Further research is needed to develop context specific exemplars and undertake additional reliability testing using a wide range of handover settings. WHAT IS ALREADY KNOWN ABOUT THIS TOPIC: CONTRIBUTION OF THE PAPER. PMID- 29579505 TI - Exercises improve body composition, cardiovascular risk factors and bone mineral density for menopausal women: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Menopause has been considered as an aggravating factor for developing cardiovascular diseases and the metabolic syndromes for women. Exercise might be an effective intervention for reducing such threats. OBJECTIVE: The purpose of this study was to evaluate the exercise effects on body composition, cardiovascular risk factors, and bone mineral density of menopausal women. METHODS: Two reviewers did a complete search of five electronic database (Medline, PubMed, Cochrane Central Register of Controlled Trials, CINAHL, and the Chinese Electronic Periodical Service) records up to January 31, 2014. Randomized controlled trials (RCTs) that compared female menopausal participants with exercises, and those without exercise or with placebo were included. Risk of bias was classified based on the Cochrane Collaboration tool, the meta-analysis was conducted using Comprehensive Meta-Analysis Version 2.2. The study selection, data extraction, and validation were performed independently by the 2 reviewers. RESULTS: A total of 17 RCTs with 792 participants were included for meta analysis. Among the eight RCTs (247 participants), a moderate effect size of exercise on body fat was found (SMD=-0.34, 95% CI: -0.60 to -0.08). In five RCTs (195 participants), a moderate effect size of exercise on waist circumference (SMD=-0.39, 95% CI: -0.68 to -0.09), in seven RCTs (162 participants), a moderate effect size on triglyceride level (SMD=-0.37, 95% CI: -0.62 to -0.11), and in five RCTs (311 participants), a moderate effect size on bone mineral density (SMD=0.38, 95% CI: 0.08-0.68). Subgroup analysis revealed a significant effect of aerobic exercise on body fat (SMD=-0.29, 95% CI: -0.53 to -0.06), and a short term exercise on body fat (SMD=-0.50, 95% CI: -0.89 to -0.11) and on triglycerides (SMD=-0.42, 95% CI: -0.79 to -0.04). The trials included in this meta-analysis were small and some had methodologic limitations. CONCLUSIONS: This study provides evidences to clinical practice for menopause women that exercise, compared with nonexercise or placebo exerted significant benefits on body fat, waist circumference, triglyceride level, and lumbar spine bone mineral density. Particularly, aerobic exercise did help menopausal women improve their body fat. A short-term exercise intervention had a benefit on not only body fat but also triglyceride level. However, well-designed, well-executed RCTs, and a detailed long-term clinical research should be needed in the future. PMID- 29579506 TI - A preliminary psychometric evaluation of the eight-item cognitive load scale. AB - AIM: The aim of this article is to report the psychometric properties of the eight-item cognitive load scale. BACKGROUND: According to cognitive load theory, the formatting and delivery of healthcare education influences the degree to which patients and/or family members can engage their working memory systems for learning. However, despite its relevance, cognitive load has not yet been evaluated among surrogate decision makers exposed to electronic decision support for healthcare decisions. To date, no psychometric analyses of instruments evaluating cognitive load have been reported within healthcare settings. METHODS: A convenience sample of 62 surrogate decision makers for critically ill patients were exposed to one of two healthcare decision support interventions were recruited from four intensive care units at a tertiary medical center in Northeast Ohio. Participants were administered a battery of psychosocial instruments and the eight-item cognitive load scale (CLS). RESULTS: The CLS demonstrated a bidimensional factor structure with acceptable discriminant validity and internal consistency reliability (Cronbach's alpha = 0.75 and 0.89). CONCLUSIONS: The CLS is a psychometrically sound instrument that may be used in the evaluation of decision support among surrogate decision makers of the critically ill. The authors recommend application of the cognitive load scale in the evaluation and development of healthcare education and interventions.

PMID- 29579508 TI - Effects of Mandala Art Therapy on Subjective Well-being, Resilience, and Hope in Psychiatric Inpatients. AB - PURPOSE: This study investigated the effects of Mandala art therapy on subjective well-being, resilience, and hope among psychiatric inpatients. METHODS: Recruited 36 people who had been treated as inpatients in a psychiatric ward at a university hospital in Seoul, South Korea, and divided them evenly into experimental and control groups. The experimental group was required to attend a total of 8 sessions of Mandala art therapy, twice per week, between August 11 and October 30, 2015; measures of the three main variables were administered at pre test and post-test in both groups. RESULTS: Hope significantly increased in both groups, but the overall increase was greater in the experimental group (mean score of 9.5 and 15.3 at pre- and post-test, respectively) than in the control group (10.9 and 11.9). CONCLUSION: These results suggest that Mandala art therapy can have a positive effect on the hope of psychiatric inpatients. However, further research concerning its effects on subjective well-being and resilience, as well as other psychological constructs, is warranted to better understand the effects of Mandala art therapy on psychiatric inpatients. PMID- 29579509 TI - A Comparison of Aggression and Self-injury Among Type 1 Diabetic and Healthy Adolescents: A Sample From Turkey. AB - BACKGROUND: Adolescents tend to have risky behaviors like aggression and self injury due to the age period characteristics. The risk of aggression and self injury may increase in adolescents with the addition of chronic diseases. OBJECTIVES: This study was conducted descriptively to determine and compare the aggression and self-injury in those with type 1 diabetes mellitus (T1DM) and healthy counterparts. METHODS: The study sample consisted of 60 adolescents with T1DM followed up in the child endocrinology polyclinic of a university hospital and 319 healthy counterparts, 15-18 aged, at 9th-12th grade at high school. In the study, the permission of the institution, Ethical Committee, the parent and adolescent consent, the data were collected using a questionnaire form, Aggression Questionnaire (AQ) and Inventory of Statements About Self-injury (ISAS). The descriptive statistics, Shapiro-Wilk, Mann-Whitney U, Student t, Chi square, Spearman correlation tests were used for analyzing data. RESULTS: The mean scores of AQ all subscales and the total scale of healthy adolescents were higher than adolescents with T1DM (p<0.05). Mean ISAS scores of adolescents with T1DM were higher than the healthy ones (p>0.05). The mean scores of autonomic function, social function and ISAS were positively moderately correlated with the mean scores of total aggression in both healthy and diabetic adolescents (p<0.05). CONCLUSIONS: Considering the age period characteristics, training about anger-stress management and effective communication skill to adolescents and their parents may be recommended by health professionals.

AB - Hospital discharge planning for clients with schizophrenia reduces client rehospitalization rates and improves their medication adherence. The effectiveness of caregiver participation in hospital discharge planning has seldom been explored. The purpose of this study was to examine the effectiveness of caregiver participation in hospital discharge planning for clients with schizophrenia in reducing caregiver burden and improving health status. A quasi experimental research design was adopted. The research location was in a psychiatric hospital in Northern Taiwan. The target population was caregivers of inpatients with schizophrenia. Nurses served as care coordinators and provided six-step hospital discharge planning services to caregivers. Structured questionnaires were employed to measure caregiver burden and health status. Intervention effect was tested using analysis of covariance in which outcome measure at pretest and selected demographic variables were treated as covariates. A total of 114 caregivers completed pretest and posttest evaluations, with 57 people in each group. A significant difference was found between the experimental and the control group regarding the caregiver burden and health status (P<0.001) The caregiver burden and health status of the experimental group improved more significantly compared with the control group. The caregiver-involved discharge planning process developed in this study effectively reduced the burden placed on caregivers and improved their health status. Mental health nurses can serve as the main care coordinators for assessment, planning, referral and provision of the required services. Caregiver-involved hospital discharge planning should become part of the routine care process.

PMID- 29579512 TI - Eating Behaviors and Related Factors in Psychiatric Patients. AB - The aim of this study was to determine the risk of eating disorders and associated risk factors in individuals with psychiatric disorders. Patients who were hospitalized in a psychiatry clinic of the university hospital between the dates of February 2014 and July 2014 constitute sample for the study. The study sample consisted of a total of 216 patients. Data were collected using a questionnaire form and the Eating Attitude Test. The mean age of the patients was 37+/-0.5, and 56.9% of the patients were female. Problems in eating behavior were observed in 11.6% of the patients, and a statistically significant relationship was found between the risk of eating disorders and diagnosis, gender, exercise and self-perception of weight. The risk of eating disorders was more frequently observed in patients diagnosed with depression, in female patients with a self perceived weight problem and do not exercise. PMID- 29579513 TI - A Comparison of Eating Attitudes Between Vegans/Vegetarians and Nonvegans/Nonvegetarians in Terms of Orthorexia Nervosa. AB - This descriptive study was performed to compare signs of orthorexia nervosa and eating habits and attitudes of vegans/vegetarians and nonvegans/nonvegetarians. The study sample included 62 people, of whom 31 were vegan/vegetarian and 31 were nonvegan/nonvegetarian. Data were gathered with a personal characteristics form, Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test-40 and Maudsley Obsessive Compulsive Inventory. There were not any significant differences between scores for Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test 40 and Maudsley Obsessive Compulsive Inventory (p>0,05). As scores for Orthorexia Nervosa Evaluation Scale-11 decreased, predisposition to orthorexia nervosa increased. Therefore, although correlation coefficients were negative, they were considered positive. There was a significant, negative relation between Eating Habits Test-40 scores and Orthorexia Nervosa Evaluation Scale-11 scores (r= 0.290, p=0.002) and between Maudsley Obsessive Compulsive Inventory scores and Orthorexia Nervosa Evaluation Scale-11 scores (r=-0.319, p=0.012). As poor eating habits and obsessive symptoms increased, so did orthorectic symptoms. In light of obtained results, it seems that people become vegan/vegetarian mainly for ethical reasons and that veganism/vegetarianism is not associated with obsession of healthy eating. PMID- 29579514 TI - The Mental Health Team: Evaluation From a Professional Viewpoint. A Qualitative Study. AB - BACKGROUND: Health care institutions include workers who must operate in accordance with the requirements of the position, even though there are psychosocial influences that can affect the stability of the worker. AIMS: To analyze the organizational culture of the team of professionals who work in the mental health network. METHOD: A qualitative methodology was used to assess a sample of 55 mental health professionals who have been practicing for at least 5years. RESULTS: "Team" was the overall topic. The subtopics within "Team" were: getting along in the unit, getting along with the patient, personal resources for dealing with patients, adaptive resources of team members and, resources that the team uses in their group activities. CONCLUSION: It was observed that the team does not work with a common objective and needs an accepted leader to manage the group. The definition and acceptance of roles can result in conflict. By increasing the skill level of each worker, the multidisciplinary team would be more collaborative. PMID- 29579515 TI - Exploration of Aggression/Violence Among Adult Patients Admitted for Short-term, Acute-care Mental Health Services. AB - BACKGROUND/PURPOSE: The purpose of the study was to explore and describe: (a) the prevalence of incidents of aggression and violence among patients, including frequency, kinds and severity of incidents of among patients; target of the aggression; (b) situational factors including time of location and time of event; and (c) staff interventions. We describe the relationships among variables to answer the following research questions: (1) What factors are associated with incidents of aggression and violence, and (2) are factors modifiable? METHODS: The exploratory descriptive study used data collected by retrospective chart review over a three-year period; the dates of January 1, 2011 to December 31, 2013. A medical record was included if it met the following criteria: 1) person ages 18-75years; 2) admitted to the psychiatric mental care unit (PMCU) during the designated time frame; 3) the length of stay was up to 7days; and 4) during this time the person made a verbal threat of violence or exhibited violent behavior towards property, self, another patient, or a member of the hospital staff. We examined data for a relationship among score on risk assessment items, sociodemographic factors, and outcome variables. We employed a variety of statistical analytic approaches to describe our data and uncover relationships among variables. RESULTS: There were 132 incidents of aggression/violence between January 1, 2011 and December 31, 2013Of the 93 patients, 68% (n=63) were male and 32% (n=30) were female. Their ages ranged from 20 to 57years with a mean age of 37 for females and 39 for males. Significant associations were found between type of intervention and patients' admitting diagnoses: Chi2 (5, N=97)=11.603, p=0.004. Significant associations were also found with regard to drug history, Chi2(1, n=96)=4.673, p=0.03 and history of violence, Chi2(1, N=91)=7.618, p=0.006. Key variables were target (the staff) and location (the hallway). Multiple factor analysis yielded inconclusive results, as numerous factors were identified and variable loadings were weak possibly due to the small sample size and high number of relevant variables. CONCLUSION: Findings from this study can be used to improve high quality care for hospitalized patients with acute mental health problems. All incidents of aggression/violence cannot realistically be prevented. Staff must stay vigilant for self-safety. The hallway may be modified to reduce visual and auditory stimuli. PMID- 29579516 TI - Impact of Menopause on Quality of Life in Community-based Women in China: 1 Year Follow-up. AB - Quality of life (QOL) throughout menopause has become an outcome variable requiring measurement in clinical care. Staff nurses can provide earlier nursing during the menopausal transition (MT) stage. The purpose of this study was to describe the changes of QOL in different stages of the MT according to The Stages of Reproductive Aging Workshop (STRAW) in Chinese women in community settings. Prospective longitudinal study design was used to analyze QOL of 327 community women age 30-65years old. They were followed up at 1-year. An instrument including the Chinese version of the Menopause-Specific Quality of Life Questionnaire was used to obtain data. A gradual decline in QOL was seen from premenopausal to menopausal transition (MT) and in postmenopausal women. Significant differences were observed in vasomotor, physical and sexual scores at baseline and follow-up (P<0.05). Significant differences in vasomotor scores were observed between baseline and follow-up for women in the premenopausal and Late MT stages (P<0.05). There were significant differences in psychosocial and physical scores between baseline and follow-up in the Late MT stage (P<0.05). Menopause might have a negative impact on QOL independent of age in community based women in China. There seemed to be a potential model of the relationship of menopause status to change in QOL, but this needs supporting evidence from longer longitudinal studies.

PMID- 29579518 TI - Correlations between stress, anxiety and depression and sociodemographic and clinical characteristics among outpatients with heart failure. AB - : Aim To describe and investigate correlations among anxiety, stress and depression and identify their relationship with sociodemographic and clinical characteristics of patients with heart failure. METHODS: This is an analytical cross-sectional study. Sociodemographic and clinical characteristics were collected, along with levels of anxiety, stress and depression from 309 outpatients. RESULTS: The mean levels of stress, anxiety and depression were correlated but low. Time since diagnosis, the disease's functional class, family income, and smoking influenced stress. Functional class and Chagas disease influenced anxiety and depression. Being unemployed and smoking influenced anxiety, while being a homeowner influenced depression. CONCLUSION: These findings should be considered when planning nursing interventions. PMID- 29579519 TI - Prevalence of Workplace Violence Against Chinese Nurses and Its Association with Mental Health: A Cross-sectional Survey. AB - OBJECTIVES: The aim of this study to investigate the prevalence of workplace violence (WPV) in nurses in hospitals in China, and its influence on nurses' mental health. METHODS: A cross-sectional, anonymous survey was conducted with 886 nurses (effective response rate: 87.46%) from Heilongjiang Province of China. RESULTS: Findings revealed that 595 of the 886 participating nurses (67.2%) were exposed to different levels of WPV. Further, WPV was correlated positively with nurses' anxiety (r=0.256, P<0.01) and depression (r=0.131, P<0.01) levels. In addition, this survey demonstrated that service years (r=0.263, P<0.01) played a moderating role in the relationship between WPV and anxiety, and gender (r=0.135, P<0.01) played a moderating role in the association between WPV and depression. CONCLUSIONS: WPV is an extensive problem in the work setting of nurses and it poses a major threat to Chinese nurses. Chinese nurses encounter hospital workplace violence frequently, and WPV has a considerably negative impact on the mental health and well-being of the nurses. It is critical to establish a more secure working environment for Chinese nursing staff to minimize the health threats caused by the negative outcomes associated with WPV, such as symptoms caused by anxiety and depression. This study also confirmed that new nurses and female nurses were more likely to be affected by WPV. Thus, addressing WPV should be one of the top concerns for both the government and the society. PMID- 29579520 TI - Depression in Community-Dwelling Elderly Patients With Heart Failure. AB - The present cross-sectional study discussed the relationship between comorbid depression, demographic characteristics, clinical characteristics, and dietary self-efficacy among Taiwanese community-dwelling elderly patients with heart failure (HF). Specifically, the study examined 175 community-dwelling elderly patients with HF between July 2013 and June 2014. In total, 47.13% of the patients exhibited symptoms of depression. Those without a spouse, who were currently employed, who had an ejection fraction <30%, who had been readmitted to the hospital 2 or more times, and who had a high level of HF symptom distress were significantly more likely to be depressed. Therefore, it is crucial that care programs designed for these patients include the self-management of HF symptoms, psychological consultations, cognitive behavioral therapy, and physical exercise. PMID- 29579521 TI - Social Support as a Mediator of Physical Disability and Depressive Symptoms in Chinese Elderly. AB - The relationship between physical disability and depressive symptoms has been associated with social support. Different aspects of social support may play distinct roles in health-related quality of life. The aim of this study was to examine the mediation of social support in the relationship between physical disability and depressive symptoms among old people in Mainland China. Subjective support and utilization of support mediated the relationship between ADL and depressive symptoms, with the indirect effect of subjective support and utilization of support at 0.038 and 0.030 respectively (the total effect was 0.180). Subjective support was negatively associated with depressive symptoms in independent elderly people, utilization of support was negatively associated with depressive symptoms in partially dependent elderly people, and utilization of support had a greater association with geriatric depressive symptoms than subjective support in severely dependent elderly people. Social support mechanism and positive psychological intervention should be established and introduced in accordance with the physical disability of the elderly people, to protect them from depressive symptoms. PMID- 29579522 TI - The Relationship of Maternal-Fetal Attachment and Postpartum Depression: A Longitudinal Study. AB - AIM: To determine the relationship between maternal-fetal attachment and postpartum depression. METHODS: This longitudinal study was done on 242 primiparous women in 2016. The data collection tools used included a socio demographic characteristics questionnaire and Cranley's Maternal-Fetal Attachment Scale - which was completed at 32-37weeks of pregnancy - and obstetrics information questionnaire and the Edinburgh Postnatal Depression Scale -which was completed at 6-8weeks after birth. A multivariate linear regression was used to estimate the extent to which maternal-fetal attachment affected postpartum depression. RESULTS: The mean Maternal-Fetal Attachment score was 90.0 (SD: 10.3) from the attainable score of 23 to 115. The mean depression score was 8.0 (SD: 3.8) from the attainable score of 0 to 30. Pearson's correlation test showed a significant inverse relationship between maternal-fetal attachment and postpartum depression (r=-0.196, p<0.001). The multivariate linear regression model showed that postpartum depression correlated significantly with the mother's age and two dimensions of attachment including differentiation of self from fetus and attributing characteristics to the fetus. CONCLUSION: According to the findings, maternal-fetal attachment is one of the factors contributing to postpartum depression. Greater emphasis should be placed on the preparation of pregnant women for accepting their maternal role, so that the maternal-neonatal relationship can be enhanced and postpartum depression thus reduced. PMID- 29579523 TI - Impact of the I2AO2 interdisciplinary program led by nursing on psychological comorbidity and quality of life: Randomized controlled clinical trial. AB - OBJECTIVE: Obesity is an entity of highly prevalent multifactorial origin with associated metabolic and psychological comorbidity, causing a negative impact on the quality of life of those who suffer from it. The objective is to evaluate the impact of an interdisciplinary program for nurse-led obesity on quality of life related to health and anxiety. METHODS: Randomized controlled clinical trial with a sample of 74 subjects diagnosed with obesity (EG: n=37; CG: n=37). The intervention consisted of a 12-month interdisciplinary program (with pre-test, 12month and 24month follow-up) coordinated by nurses. RESULTS: The anxiety analysis shows that there is no effect of the intervention on S-STAI (F2; 144=0.246; p=0.782), which has increased in both groups. However, there is an effect on T-STAI (F2; 144=8872; p<0.001), which only increases in the control group. The interdisciplinary program has significantly improved health-related quality of life (SF-36), both in physical health parameters as well as in mental health. CONCLUSION: The interdisciplinary program led by nursing professionals has improved the quality of life related to health and has prevented the increase of anxiety-trait in participants, maintaining the long-term effects. PMID- 29579524 TI - Effects of Relaxation Therapy on Anxiety Disorders: A Systematic Review and Meta analysis. AB - AIM: To explore the effect of relaxation therapy applied to people with anxiety disorders. METHODS: Systematic review with meta-analysis. RESULTS: Sixteen Randomized Control Trials (RCTs) were included for meta-analysis to determine the effect of relaxation therapy. The overall effect of relaxation therapy on symptom of anxiety was significant with Hedges' g=0.62 (95% CI: 0.42-0.81), which indicates a medium-high effect; heterogeneity was statistically significant with I2=48.84. Subgroup analysis exploring the possible causes of heterogeneity found that types of comparison of TAU and CBT was significant (Q=4.20, p=0.04). The effect of relaxation therapy on symptoms of depression, phobia, and worry was significant; Hedges' g=0.44 (95% CI: 0.30-0.59), 0.40 (95% CI: 0.06-0.75), 0.54 (95% CI: 0.28-0.79), respectively. CONCLUSION: The results of this study provide evidence for the effectiveness of relaxation therapy for people with anxiety disorders. Therefore, relaxation therapy can be selected as a useful intervention for reducing negative emotions in people with anxiety disorders. PMID- 29579525 TI - Do Males and Females Conceptualise Work and Social Impairment Differently Following Treatment for Different Mental Health Problems? AB - The Work and Social Adjustment Scale (WSAS) is used by psychiatric nurses for screening and evaluating patients' treatment outcomes for a variety of mental health problems. This study investigated longitudinal and gender measurement invariance of WSAS using structural equation modeling within a help-seeking problem gambling sample (n=445), and an intervention program for depression and anxiety sample (n=444). The concept of functional impairment was defined by all WSAS items in males and females at pre- and post-treatment assessments. These findings confirm that the WSAS is a robust and efficacious instrument for evaluating treatment outcomes in two differing populations.

PMID- 29579527 TI - Knowledge and Attitude of Family Member of Mentally Ill Patient Regarding Restraint, 2016. AB - BACKGROUND: People who have observed or are aware that a consumer has been restrained may experience distress, confusion, concern, anger or fear and perceive as punishment. However, studies that examine the perspective of patient's family are limited. This study has explored the knowledge and attitude of family member of mentally ill patient. METHOD: A descriptive cross-sectional study was carried out among family member of mentally ill patient at Punarjeevan Hospital, Balkumari, Lalitpur to assess the knowledge and attitude of family member of mentally ill patient regarding restraint. Interview schedule was used to collect data related to knowledge and attitude regarding restraint along with demographic features. RESULT: The average score of knowledge regarding physical restraint was 30.66 (72.99%) and average attitude score was 4.17 (83.31%). In the study 40% relationship was found between knowledge and attitude. Regarding the association between knowledge and selected socio-demographic variables, knowledge was found to be associated with age, educational level and relation with patient of respondents. In terms of association between attitude and selected socio demographic variables, attitude was found to be associated with relation with patient of respondents. CONCLUSION: This study concludes that family member has relevant knowledge regarding physical restraint but the knowledge regarding risk and consequences of physical restraint was lacking. In terms of attitudes about physical restraint over all attitude was found to be positive among family members but attitude regarding feeling of patient towards physical restraint was contrast. PMID- 29579528 TI - Decision-making Capacity for Treatment of Psychotic Patients on Long Acting Injectable Antipsychotic Treatment. AB - OBJECTIVE: Providing informed, consent requires patients' Decision-Making Capacity for treatment. We evaluated the Decision Making Capacity of outpatients diagnosed with schizophrenia and schizoaffective disorder on treatment with Long Acting Injectable Antipsychotic medication. METHOD: This is a retrospective, cross-sectional, correlational study conducted at two Depot Clinics in Athens, Greece. Participants included 65 outpatients diagnosed with schizophrenia and schizoaffective disorder on treatment with Long Acting Injectable Antipsychotics. RESULTS: Over half of the participants showed poor understanding of the information given regarding their disease and treatment (Understanding subscale), however >70% seemed to comprehend the relevance of this information to their medical condition (Appreciation subscale). Moreover, half of the participants reported adequate reasoning ability (Reasoning subscale), whilst patients who gained >7% of their body weight scored statistically significantly higher in the subscales of Understanding and Appreciation. CONCLUSION: Our results suggest that there is a proportion of patients with significantly diminished Decision Making Capacity, hence a full assessment is recommended in order to track them down. Further research is needed to better interpret the association between antipsychotic induced weight gain and Decision Making Capacity in patients suffering from schizophrenia or schizoaffective disorder. PMID- 29579529 TI - Pathological Gambling among Italian Nursing Students. AB - PURPOSE: To investigate the role of psychiatric dimensions, behavioral or substance addictions and demographical variables as determinants of pathological gambling among nursing students. DESIGN: Multicenter cross-sectional study. METHODS: From June to October 2015 a survey was carried out among Italian Nursing students. Data were collected using a six-section tool. FINDINGS: Nursing students who completed the survey numbered 1083, 902 (83.3%) had some problems with gambling and 29 (2.7%) showed pathological gambling. Percentage of pathological gambling was significantly associate with illicit drug/alcohol use (65.5%; p=0.001) and with male gender (58.6%) comparing to student nurse with non pathological gambling (20%) and those with some problem (24.2%). Significant main effect was observed for IAT score (Beta=0.119, t=3.28, p=0.001): higher IAT scores were associated with higher SOGS scores. CONCLUSIONS: Italian nursing students have some problems with gambling and pathological gambling problem, and males are those who have more problems. Results might be useful for faculties of health professionals to identify students at risk in an early stage, to direct prevention tailored interventions. CLINICAL RELEVANCE: Nursing faculties should be aware of the prevalence of Gambling among students. Prevention interventions should be planned to minimize the risk of gambling behavior in the future nurses' health care workers.

PMID- 29579533 TI - Chained nuclei and python pattern in skeletal muscle cells as histological markers for electrical injury. AB - Electrical injury is damage caused by an electrical current passing through the body. We have previously reported that irregular stripes crossing skeletal muscle fibers (python pattern) and multiple small nuclei arranged in the longitudinal direction of the muscle fibers (chained nuclear change) are uniquely observed by histopathological analysis in the skeletal muscle tissues of patients with electrical injury. However, it remains unclear whether these phenomena are caused by the electrical current itself or by the joule heat generated by the electric current passing through the body. To clarify the causes underlying these changes, we applied electric and heat injury to the exteriorized rat soleus muscle in situ. Although both the python pattern and chained nuclear change were induced by electric injury, only the python pattern was induced by heat injury. Furthermore, a chained nuclear change was induced in the soleus muscle cells by electric current flow in physiological saline at 40 degrees C ex vivo, but a python pattern was not observed. When the skeletal muscle was exposed to electrical injury in cardiac-arrested rats, a python pattern was induced within 5 h after cardiac arrest, but no chained nuclear change was observed. Therefore, a chained nuclear change is induced by an electrical current alone in tissues in vital condition, whereas a python pattern is caused by joule heat, which may occur shortly after death. The degree and distribution of these skeletal muscle changes may be useful histological markers for analyzing cases of electrical injury in forensic medicine. PMID- 29579535 TI - Electron paramagnetic resonance of a 10B-containing heterocyclic radical. AB - Electron paramagnetic resonance measurements for a 10B-containing heterocyclic phenanthrenedione radical, (C6F5)2B(O2C14H8), were made at X-band in 9:1 toluene:dichloromethane from 10 to 293 K and in toluene from 180 to 293 K. In well-deoxygenated 0.1 mM toluene solution at room temperature hyperfine couplings to 10B, four pairs of protons and five pairs of fluorines contribute to a continuous wave spectrum with many resolved lines. Hyperfine couplings were adjusted to provide the best fit for spectra of the radical enriched in 10B and the analogous radical synthesized with 10,11B in natural abundance, resulting in small refinements of the hyperfine coupling constants previously reported for the natural abundance sample. Electron spin relaxation rates at temperatures between 15 and 293 K were similar for samples containing 10B and natural isotope abundance. Analysis of electron spin echo envelope modulation and hyperfine correlation spectroscopy data at 80 K found Axx = -7.5 +/- 0.3, Ayy = -8.5 +/- 0.3, and Azz = -10.8 +/- 0.3 MHz for 11B, which indicates small spin density on the boron. The spin echo and hyperfine spectroscopy data for the 10B -containing radical are consistent with the factor of 2.99 smaller hyperfine values for 10B than for 11B.

AB - DNA oligonucleotides containing site-specific N7-guanine monoadducts of cisplatin, diepoxybutane, and epichlorohydrin were used as templates for DNA synthesis by two bacterial DNA polymerases and human polymerase beta. These polymerases were able to bypass the lesions effectively, although the efficiency was decreased, with inhibition increasing with the size of the lesion. Fidelity of incorporation was essentially unaltered, suggesting that N7-guanine monoadducts do not significantly contribute to the mutational spectra of these agents. PMID- 29579536 TI - Novel forecasting approaches using combination of machine learning and statistical models for flood susceptibility mapping. AB - In this research, eight individual machine learning and statistical models are implemented and compared, and based on their results, seven ensemble models for flood susceptibility assessment are introduced. The individual models included artificial neural networks, classification and regression trees, flexible discriminant analysis, generalized linear model, generalized additive model, boosted regression trees, multivariate adaptive regression splines, and maximum entropy, and the ensemble models were Ensemble Model committee averaging (EMca), Ensemble Model confidence interval Inferior (EMciInf), Ensemble Model confidence interval Superior (EMciSup), Ensemble Model to estimate the coefficient of variation (EMcv), Ensemble Model to estimate the mean (EMmean), Ensemble Model to estimate the median (EMmedian), and Ensemble Model based on weighted mean (EMwmean). The data set covered 201 flood events in the Haraz watershed (Mazandaran province in Iran) and 10,000 randomly selected non-occurrence points. Among the individual models, the Area Under the Receiver Operating Characteristic (AUROC), which showed the highest value, belonged to boosted regression trees (0.975) and the lowest value was recorded for generalized linear model (0.642). On the other hand, the proposed EMmedian resulted in the highest accuracy (0.976) among all models. In spite of the outstanding performance of some models, nevertheless, variability among the prediction of individual models was considerable. Therefore, to reduce uncertainty, creating more generalizable, more stable, and less sensitive models, ensemble forecasting approaches and in particular the EMmedian is recommended for flood susceptibility assessment. PMID- 29579537 TI - Use of high metal-containing biogas digestates in cereal production - Mobility of chromium and aluminium. AB - Biogas digestate use as organic fertilizer has been widely promoted in recent years as a part of the global agenda on recycling waste and new sustainable energy production. Although many studies have confirmed positive effects of digestates on soil fertility, there is still lack of information on the potential adverse effects of digestates on natural soil heavy metal content, metal leaching and leaching of other pollutants. We have investigated the release of aluminium (Al) and chromium (Cr) from different soils treated with commercial digestates high in mentioned potentially problematic metals in a field experiment, while a greenhouse and a laboratory column experiment were used to address mobility of these metals in two other scenarios. Results obtained from the field experiment showed an increase in total concentrations for both investigated metals on plots treated with digestates as well as a significant increase of water-soluble Al concentrations. Factors that were found to be mostly affecting the metal mobility were dissolved organic carbon (DOC), pH and type of soil. Metal binding and free metal concentrations were modelled using the WHAM 7.0 software. Results indicated that the use of digestates with high metal content are comparable to use of animal manure with respect to metal leaching. Data obtained through chemical modelling for the samples from the field experiment suggested that an environmental risk from higher metal mobility has to be considered for Al. In the greenhouse experiment, measured concentrations of leached Cr at the end of the growing season were low for all treatments, while the concentration of leached Al from digestates was higher. The high irrigation column leaching experiment showed an increased leaching rate of Cr with addition of digestates. PMID- 29579538 TI - Relationship between geosorbent properties and field-based partition coefficients for pesticides in surface water and sediments of selected agrarian catchments: Implications for risk assessment. AB - Studies on pesticide behavior, adsorption-likelihood, and bioavailability vis-a vis geosorbent properties and seasons, are critical for understanding pesticide fate and risks in pesticide-prone environments. We examined the relationship between geosorbent profiles of sediments (percentage sand, silt, clay, organic carbon content) across seasons and occurrence of pesticide residues in surface water and sediment of agricultural catchments at Owan, Ogbesse and Illushi communities of Edo State, Nigeria. Pesticide concentrations were measured monthly in samples of surface water and sediments across the selected sites for 18 months. Pesticide behavior and sorption-likelihoods were examined using partition coefficients Kd (sediment-water coefficient), Koc (sediment-water coefficient normalized for organic carbon) and Log Kow (octane-water coefficient); the relationship between Kd and Koc was also examined. Results of the principal component analysis (PCA) indicated that pesticide levels in sediment and surface water were positively associated with the rainy season, total organic content (TOC), percentage silt and clay in sediment. Field-derived pesticide partition coefficients (Kd < 100 and log Koc < 3) indicated that pesticide species were largely mobile and less likely to be retained in sediments by adsorption. As such, pesticides irrespective of solubility would end up in surface water, increasing risks for pelagic biota and humans sourcing river water for domestic use. Values of Log Kow indicate that organochlorines including DDT, dieldrin, endrin and heptachlor epoxide portend significant bioaccumulation risks to humans and biota across sites. The relationship between Kd and Koc for each site fitted into a quadratic model; it depicted a biphasic behavior of pesticide adsorption and desorption to sediments revealing that concentration of organic carbon across study sites was a limiting factor determining the extent of pesticide adsorption. This study demonstrates that understanding pesticide mobility using field-based partition coefficients could give a clearer picture of pesticide risks to biota and human populations.

AB - INTRODUCTION: Intra-Gastric Balloon (IGB) is increasingly used as a non-operative management strategy in bariatric patients. However, as IGB use has become more prevalent, new potentially life-threatening adverse effects have emerged. We report a case of IGB-related acute pancreatitis from a tertiary referral hospital. A literature review of electronic databases was conducted to identify other cases PRESENTATION OF CASE: A 20-year-old female presented to the emergency department with acute onset of epigastric pain on day-1 post-insertion of an IGB (Orbera(r)). The diagnosis of acute pancreatitis was made on the basis of the clinical picture, with radiological and serological confirmation. Complete resolution of symptoms promptly followed endoscopic removal of the balloon. DISCUSSION: We examine all prior reported cases of IGB associated pancreatitis in the literature, as well as the impact of the particular balloon subtypes. Mass effect of the device on the pancreas or dislodgement of the rigid catheter into the second part of the duodenum appear to be the underlying cause in all cases. While there were no deaths reported, major sequelae have been noted, including presence of mucosal ischemia and failure to retrieve the balloon endoscopically, necessitating laparotomy. CONCLUSION: Although the incidence of IGB-induced pancreatitis is still rare, this complication which must be highlighted as a potentially serious adverse outcome.

AB - Trichloroethylene (TCE) was widely used as an industrial solvent which could cause severe liver damage. The histone chaperone SET have been identified as an important mediator of TCE-induced hepatic cytotoxicity in our previous study; however, the underlying regulatory mechanisms remain poorly understood. In this study, we found a total of 136 histone acetylation sites involved in TCE-induced hepatic cytotoxicity with the technique of Triton-acid-urea polyacrylamide gel electrophoresis (TAU-PAGE) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Importantly, 17 histone acetylation sites were revealed to be mediated by SET in TCE-induced cytotoxicity. The acetylation of histone H2AK9 (H2AK9ac) was further validated by Western-blot analysis. The data showed that TCE treatment increased the acetylation of H2AK9 in hepatic L-02 cell and decreased the one in SET-knockdown L-02 cells. Besides, levels of the histone deacetylases (HDACs, including HDAC1, HDAC2, and HDAC3) was also analyzed. Interestingly, the level of HDAC1 was aberrantly suppressed in TCE-treated L-02 cells while enhanced in SET-knockdown L-02 cells. To further explore the potential role of HDAC1 in SET-mediated hepatic cytotoxicity of TCE, we employed RNA interference (RNAi) to knockdown HDAC1 in both wide type L-02 and SET knockdown cells. The results showed that the siRNA inhibition of HDAC1 increased the acetylation of H2AK9. Taken together, our data suggested that SET promoted the acetylation of H2AK9 via suppressing the level of HDAC1, which was involved in SET-mediated hepatic cytotoxicity of TCE.

This study aimed to investigate the effects of nicorandil on allergic asthma induced by ovalbumin (OVA) in mice in comparison with dexamethasone. Mice were sensitized to OVA (on days 0 and 7) and challenged with OVA three times (on days 14, 15 and 16). Nicorandil was given orally for 5 days 1 h before OVA treatment in days of challenge. Progression of asthma was accompanied by significant elevation in the lung/body weight index, LDH, total protein, IL-13 and NF-kappaB levels besides inflammatory cell counts in BALF; Also pulmonary MDA and NO contents were significantly increased but GSH and SOD levels were decreased. Histopathological alterations in lung tissues were also observed. In contrast, nicorandil treatment significantly alleviated OVA-induced lung injury. In conclusion, our results proposed that nicorandil is equivalent to dexamethasone in ameliorating allergic asthma by restoring oxidant/antioxidant balance and reducing inflammation. PMID- 29579543 TI - IGFBP-3 plays an important role in senescence as an aging marker. AB - Aging study requires aging markers to measure the degree of aging process. The aging markers such as senescence associated-beta-galactosidase (SA-beta-gal), lipofuscin, telomere, p53 and p16 have been known in aging study until now. Therefore, we investigated the role of genes and proteins related to aging in young, senescent and H2O2-induced old cells to develop a novel aging marker involved in aging mechanism. After cellular aging was compared in young, senescent and H2O2-induced old cells using SA-beta-galactosidase staining assay, the expression level of genes and proteins in senescent and H2O2-induced old cells were compared and analyzed with those of young cells using RT-PCR, western blot and immunofluorescence staining. First of all, the senescent cells and the cells aged by H2O2 showed higher level of SA-beta-galactosidase staining than young cells. In particular, the expression level of IGFBP-3 was decreased in senescent and H2O2-induced old cells compared with young cells. Moreover, the senescent and H2O2-induced old cells showed higher expression levels of p-PI3K, Akt-1, p-mTOR, p-FoxO1 and FoxO1 than young cells. Furthermore, the expression levels of p300, Ac-p53, p53, p-p21 and p16 were significantly increased in senescent and H2O2-induced cells compared to young cells. However, the expression level of SIRT-1 was decreased in senescent and H2O2-induced old cells compared to young cells. In conclusion, IGFBP-3 up-regulates PI3K/Akt/mTOR signaling pathway and down-regulates autophagy during cell aging. These results suggest that IGFBP 3 could play a key role in aging study as an important aging marker.

AB - Systems and synthetic biology in the coming era has the ability to manipulate, stimulate and engineer cells to counteract the pathogenic immune response. The inherent biological complexities associated with the creation of a device allow capitalizing the biotechnological resources either by simply administering a recombinant cytokine or just reprogramming the immune cells. The strategy outlined, adopted and discussed may mark the beginning with promising therapeutics based on the principles of synthetic immunology. PMID- 29579545 TI - Increase in serum Interleukin-10 does not alleviate pro-inflammatory MCP-1 production in obese pregnancies. AB - Maternal cytokine profiles during pregnancy are characterized by significant deviations, varying substantially between gestational time points and tissues. Obesity, in turn, is linked with low-grade inflammation in adipose tissue and increased concentrations of systemic inflammatory mediators. However, the balance of pro- and anti-inflammatory cytokines in obese pregnancy has remained elusive. In view of the demonstrations that the obesity is a global epidemic in the population at reproductive age with a strong intergenerational impact, we investigated the relation of gestational immune adaptations and obesity-induced inflammation. We found a significant decrease in systemic IL-1beta and MCP-1 concentration from 1st to 3rd trimester of pregnancy while IL-10 concentration increased, respectively. However, in obese pregnancies this reduction of pro inflammatory mediators was not detected. This may constitute an additional risk factor in obese pregnancies in which the concentration of MCP-1 is already upregulated compared to normal weight mothers. PMID- 29579546 TI - Role of selective blocking of bradykinin B1 receptor in attenuating immune liver injury in trichloroethylene-sensitized mice. AB - Trichloroethylene (TCE) is able to induce trichloroethylene hypersensitivity syndrome (THS) with multi-system immune injuries. In our previous study, we found kallikrein-kinin system (KKS) activation, including the bradykinin B1 receptor (B1R), which contributed to immune organ injury in TCE sensitized mice. However, the mechanism of B1R mediating immune dysfunction is not clarified. The present study initiates to investigate the potential mechanism of B1R on liver injury. We establish a TCE sensitized BALB/c mouse model to explore the mechanism with or without a B1R inhibitor R715. We found B1R expression was increased in TCE sensitization-positive mice. As expect, hepatocyte intracellular organelles and mitochondria disappeared, glycogen particles reduced significantly as well in TCE sensitization-positive mice via the transmission electron microscopic examination, meanwhile, R715 alleviated the deteriorate above. The blockade of B1R resulted in a significant decreased p-ERK1/2 and increased p-AKT expression. The expression of CD68 kupffer cell and its relative cytokine, including IL-6 and TNF-alpha, increased in TCE sensitization-positive mice and decreased in R715 pretreatment TCE sensitization-positive mice. Together, the results demonstrate B1R plays a key role in ERK/MAPK and PI3K/AKT signal pathway activation and inflammation cytokine expression in immune liver injury induced by TCE. B1R exerts a pivotal role in the development of TCE induced liver injury. PMID- 29579547 TI - Transfection of bone marrow derived cells with immunoregulatory proteins. AB - In vitro electroporation gene transfer was first performed in 1982. Today, this technology has become one of the major vehicles for non-viral transfection of cells. All non-viral transfections, such as calcium phosphate precipitation, lipofection, and magnetic transfection, have been shown to achieve a transfection efficiency of up to 70% in commonly used cell lines, but not in primary cells. Here we describe the use of electroporation to transfect primary mouse bone marrow-derived cells, such as macrophages (Mphi) and dendritic cells (DCs) with high efficiencies (45%-72%) and minimal cell death. The transfection efficiencies and cell death varied depending on the culture duration of the DCs and Mphi. Moreover, the electroporation efficiency was increased when conditioning medium was used for culturing the cells. Furthermore, we demonstrated that measuring the plasmid-encoded secreted proteins is a highly sensitive method for determining the transfection efficiency. In summary, electroporation with plasmid vectors is an efficient method for producing DCs and Mphi with transient expression of immunoregulatory proteins. PMID- 29579548 TI - Likelihood-based structural analysis of electron microscopy images. AB - Likelihood-based analysis of single-particle electron microscopy images has contributed much to the recent improvements in resolution. By treating particle orientations and classes probabilistically, uncertainties in the reconstruction process are explicitly accounted for, and the risk of bias towards the initial model is diminished. As a result, the quality and reliability of the reconstructions have greatly improved at manageable computational cost. Likelihood-based analysis of electron microscopy images also offers a route to direct coordinate refinement for dynamic systems, as an alternative to 3D density reconstruction. Here, we review recent developments in the algorithms used for reconstructions of high-resolution maps, and in the integrative framework of combining likelihood methods with simulations to address conformational variability in cryo-electron microscopy. PMID- 29579549 TI - Neighborhood collective efficacy, parental spanking, and subsequent risk of household child protective services involvement. AB - Children exposed to negative neighborhood conditions and parental spanking are at higher risk of experiencing maltreatment. We conducted prospective analyses of secondary data to determine the effects of neighborhood collective efficacy and parental spanking on household Child Protective Services (CPS) involvement, and whether spanking mediates the relationship between neighborhood collective efficacy and CPS involvement. The sample (N = 2,267) was drawn from the Fragile Families and Child Wellbeing Study (FFCWS), a stratified random sample of 4,789 births between 1998-2000 in 20 large U.S. cities. Logistic regression models were employed to test the effects of neighborhood collective efficacy and spanking at child age 3 on mother's report of CPS contact during the subsequent two years. The product-of-coefficient approach was used to test the mediation hypothesis. One aspect of neighborhood collective efficacy (i.e., Social Cohesion/Trust) is associated with lower odds of CPS involvement (OR = .80, 95% CI 0.670-0.951) after controlling for Informal Social Control, parental spanking, and the covariates. Parental spanking predicts increased odds of CPS involvement during the next two years (OR = 1.38, 95% CI 1.001-1.898), net of neighborhood collective efficacy and the covariates. The mediation hypothesis is not supported. Promoting both cohesive and trusting relationships between neighbors and non-physical discipline practices is likely to reduce the incidence of household CPS involvement.

PMID- 29579551 TI - Anti-GAD antibodies in a cohort of neuropsychiatric patients. AB - OBJECTIVE: Antiglutamate decarboxylase (anti-GAD) antibodies are associated with several neurological manifestations, like epilepsy and movement disorders. However, in daily neurological practice, it remains hard to define when to test for anti-GAD antibodies in patients with neurologic and/or psychiatric symptoms. Therefore, here, we report the patient characteristics of a large retrospective cohort of patients tested for anti-GAD antibodies in clinical practice and compare the characteristics of anti-GAD positive and anti-GAD negative patients. METHODS: We blindly assessed relevant clinical symptoms and comorbidities and functional outcome with the modified Rankin Scale (mRS) in a retrospective observational cohort of all patients in which the decision to assess anti-GAD levels had been made based solely on the presence of possible associated neurological and/or psychiatric symptoms (N=119). RESULTS: Out of 119 patients, 17 (14.3%) were anti-GAD positive. The anti-GAD positive patients had a median age of 30years (range: 3-64; 2 children). They all had epilepsy, with 8 (47%) patients reporting cognitive complaints. Psychiatric symptoms were less prevalent in anti-GAD positive patients, only 1 anti-GAD positive patient (6%) versus 34 anti-GAD negative patients (33%) reported psychiatric symptoms (p=0.021). The most frequent comorbidity of anti-GAD positive patients was diabetes mellitus type 1 (n=8). Twelve (71%) and 13 (78%) of the anti-GAD positive patients were functionally independent at the time of diagnosis and after one year, respectively (mRS score: 0 to 2). There was no significant difference in functional status at any time during follow-up compared with the anti-GAD negative group. CONCLUSION: Antiglutamate decarboxylase (anti-GAD) antibodies relate to epilepsy with or without cognitive complaints. However, psychiatric symptoms were almost absent in anti-GAD positive patients, and the presence of anti-GAD antibodies contributed little to the prognosis in our cohort. PMID- 29579552 TI - Proliferative hippocampal activity in a group of patients with Rasmussen's encephalitis: Neuronal, glial, and BDNF tissue expression correlations. AB - Rasmussen's encephalitis (RE) is a rare and devastating unilateral inflammatory brain disease that causes severe and intractable partial epilepsy. It has been shown that epilepsy and subsequent inflammation have deleterious influence on hippocampal cell survival and neurogenesis, but this still has not been systematically explored in human tissue. In this study, we investigated the correlation between inflammation and epilepsy as well as the rates of hippocampal gliogenesis and neurogenesis in a pediatric group of six patients with RE and six control cases. The dentate gyrus (DG) samples were obtained from patients who underwent surgery for intractable RE. Sections were processed for immunohistochemistry using antibodies against sex determining region Y-box 2 (Sox2), nestin, human protein encoded by MKI67 gen (Ki67), and brain-derived neurotrophic factor (BDNF). There was an increase in the number of Ki67-positive granule cells in the DG of patients with RE in comparison with the autopsy control group, but no statistical difference for Sox2-positive cells was observed between these groups. Nestin immunolabeling was less intense in the RE group while BDNF expression was increased. Neurons that were BDNF-positive were found in DG from patients with RE but not in the control group. In patients with RE, few nestin-positive cells in DG were also positive for BDNF, unlike in controls which showed no colocalization for these two markers. These results suggest a proliferation activity in the DG subfield of patients with RE, and also future studies are necessary to address the role of new cells in the hippocampus of patients with RE. PMID- 29579553 TI - A systematic review of quality of life in parents of children with epilepsy. AB - OBJECTIVES: This systematic review aimed to 1) describe the quality of life (QOL) of parents of children with childhood-onset epilepsy (CWE), 2) identify factors associated with parental QOL, and 3) evaluate the association between parents' QOL and children's psychological well-being. METHODS: We conducted a comprehensive search of MEDLINE, EMBASE, and PsycINFO and conducted forward and backward citation tracking. A total of 15 articles met inclusion criteria. Parents' QOL was compared with population norms, healthy controls, and parents of children with other chronic conditions. Factors associated with parental QOL were systematically evaluated. RESULTS: Heterogeneity in study design and reporting prevented a meta-analytic synthesis of results. The majority of studies found that parents of CWE had poorer QOL relative to healthy controls or population norms and similar QOL as parents of children with other chronic conditions. In addition, poorer parental QOL was consistently associated with greater parental anxiety and depressive symptoms and poorer socioeconomic status and child QOL. Mothers had poorer QOL relative to fathers. Seizure control was not consistently associated with parental QOL. Results highlight the impact of family environment and psychosocial factors. SIGNIFICANCE: This review suggests that parents of CWE have compromised QOL. The results are in line with previous research showing the interdependent nature of psychosocial and medical factors, with psychosocial factors playing a critical role in child and parental QOL and well-being. Interventions targeting the family unit are warranted, and healthcare providers should be aware of the bidirectional relationship of epilepsy, family environment, and child/parent health and well-being. PMID- 29579554 TI - Clinical and electrophysiological findings in patients with phenylketonuria and epilepsy: Reflex features. AB - OBJECTIVE: Phenylketonuria (PKU) is the most common form of amino acid metabolism disorders with autosomal recessive inheritance. The brain damage can be prevented by early diagnosis and a phenylalanine-restricted diet. Untreated or late-treated patients may show mental retardation and other cognitive dysfunctions, as well as motor disability and/or epilepsy. METHODS: Three patients with PKU and epilepsy were recognized to have reflex epileptic features, and there were ten consecutive adult patients with PKU and epilepsy who were evaluated retrospectively. Medical history, ages at diagnosis and therapy onset, age at seizure onset, seizure types and reflex features, neurological findings, cranial imaging, electroencephalography (EEG) findings, and final clinical condition were evaluated. Reflex epilepsy features were examined in detail. RESULTS: The cases (6 females, 4 males) were diagnosed at ages between 3.5months and 12years. All patients had various degrees of mental-motor retardation and focal or generalized seizures with age at seizure onset varied between neonatal period and 15years. Three patients had febrile seizure, 3 patients had myoclonia, and 3 patients had status epilepticus. All patients had abnormal EEG findings except one. There was a slowing of background activity, and generalized discharges were observed in 7 patients; 3 of them had asymmetrical discharges. One patient had right hippocampal sclerosis (HS), and another patient had hypointensities in the basal ganglia and corpus callosum. Reflex features were clinically observed in 3 of the patients; however, EEG results did not show any related findings. One patient had reflex seizures triggered by photic stimuli, hot water, and startling; one by photic stimuli; and the other one by startling. CONCLUSION: Reports on the clinical and electrophysiological features of adult patients with PKU were scant. We emphasized that reflex clinical features may be observed in this metabolic disease, and focal epileptiform abnormalities and asymmetry may be present in electrophysiological evaluation besides the rare association with HS. PMID- 29579555 TI - Mechanical behavior of surgical meshes for abdominal wall repair: In vivo versus biaxial characterization. AB - Despite the widespread use of synthetic meshes in the surgical treatment of the hernia pathology, the election criteria of a suitable mesh for specific patient continues to be uncertain. Thus, in this work, we propose a methodology to determine in advance potential disadvantages on the use of certain meshes based on the patient-specific abdominal geometry and the mechanical features of the certain meshes. To that purpose, we have first characterized the mechanical behavior of four synthetic meshes through biaxial tests. Secondly, two of these meshes were implanted in several New Zealand rabbits with a total defect previously created on the center of the abdominal wall. After the surgical procedure, specimen were subjected to in vivo pneumoperitoneum tests to determine the immediate post-surgical response of those meshes after implanted in a healthy specimen. Experimental performance was recorded by a stereo rig with the aim of obtaining quantitative information about the pressure-displacement relation of the abdominal wall. Finally, following the procedure presented in prior works (Simon-Allue et al., 2015, 2017), a finite element model was reconstructed from the experimental measurements and tests were computationally reproduced for the healthy and herniated cases. Simulations were compared and validated with the in vivo behavior and results were given along the abdominal wall in terms of displacements, stresses and strain. Mechanical characterization of the meshes revealed SurgiproTM as the most rigid implant and Neomesh SuperSoft(r) as the softer, while other two meshes (Neomesh Soft(r), Neopore(r)) remained in between. These two meshes were employed in the experimental study and resulted in similar effect in the abdominal wall cavity and both were close to the healthy case. Simulations confirmed this result while showed potential objections in the case of the other two meshes, due to high values in stresses or elongation that may led to discomfort in real tissue. The use of this methodology on human surgery may provide the surgeons with reliable and useful information to avoid certain meshes on specific-patient treatment. PMID- 29579556 TI - Variation of mechanical properties and oxidation with radiation dose and source in highly crosslinked remelted UHMWPE. AB - Ultra-high molecular weight polyethylene (UHMWPE) is the current gold standard for bearing materials used in total joint arthroplasty. High-dose radiation is commonly used to crosslink UHMWPE, thereby improving its wear resistance. A subsequent remelting step eliminates trapped residual free radicals to promote oxidative stability on the shelf, and to prevent material degradation over the long term. Assessment of clinically retrieved, highly crosslinked UHMWPE devices shows signs of unanticipated oxidation occurring in vivo, despite the absence of free radicals prior to implantation. These findings warrant further investigation into possible factors impacting this phenomenon along with its clinical implications. The overall objective of this work is to quantify the influence of irradiation dose and source on UHMWPE's oxidative stability, along with the effects of oxidation on the ultimate mechanical properties, including strength, ductility, and toughness. The results showed a strong positive correlation between maximum oxidation and initial transvinylene content. Critical oxidation levels in the context of mechanical property loss were determined for e-beam and gamma treatments at various radiation doses. Further, it was shown that critical oxidation was more dependent on radiation dose and less dependent on source. If in vivo oxidation persists in these devices, this can potentially lead to mechanical failure (e.g. fatigue damage) as observed in terminally gamma sterilized devices. PMID- 29579557 TI - Design of a hydraulically-driven bionic folding wing. AB - Membranous hind wings of the beetles can be folded under the elytra when they are at rest, and rotate and lift the elytra up only when they need to fly. This characteristic provides excellent flying capability and good environment adaptability. Inspired by the beetles, the new type of the bionic folding wing for the flapping wing Micro Air Vehicle (MAV) was designed. This flapping wing can be unfolded to get a sufficient lift in flight, and can be folded off flight to reduce the wing area and risk of the wing damage. The relationship between the internal pressures of the hydraulic system for the bionic wing folding varies and temperature was analyzed, the results show that the pressure within the system tends to increase with temperature, which proves the feasibility of the schematic design in theory. Stress analysis of the bionic wing was conducted, it was shown that stress distributions and deformation of the bionic wing under the positive and negative side loading are basically the same, which demonstrates that the strength of the bionic folding wing meets the requirements and further proves the feasibility of the schematic design. PMID- 29579558 TI - Does infant negative emotionality moderate the effect of maternal depression on motor development? AB - Maternal depression represents an important social/environmental factor in early childhood; however, its effect on children's motor development may vary depending on the role of infants' dispositional variables. The objective of this study is to investigate the effect of the interaction between maternal depressive symptoms in the first two years of a child's life and the child's temperamental negative emotionality on motor development during this time. Using a cross-sectional study, we assessed 272 infants aged 0 to 24 months old and their mothers. We measured the following variables: maternal depression, infant's negative emotionality, and motor development. A three-way interaction effect highlights that negative emotionality in infants and maternal depression together affect children's overall motor growth trajectory. Infants with low negative emotionality display no effect of maternal depression on motor development. Conversely, infants with high negative emotionality seem to be more susceptible to the effect of maternal depression. Specifically, high maternal depression tends to foster the negative effect of infant's negativity on motor development across time, albeit not significantly. Finally, the absence of maternal depression significantly buffers negative temperament in infants. Findings highlighted the importance of integrating different perspectives when describing early motor growth. In fact, only when considering the interdependence of potential predictors their effect on the motor growth significantly emerges. Screening for early temperamental vulnerability might help in tailoring interventions to prevent maternal depression from affecting infants' motor development. PMID- 29579559 TI - Attainment of gross motor milestones by preterm children with normal development upon school entry. AB - BACKGROUND: Little is known on the motor development of moderately preterm born (MPT) children, in comparison with early preterm born (EPT) children and fullterm born (FT), for children with normal motor outcomes at school entry. AIMS: To compare attainment rates of gross motor milestones reached between ages 1-24 months for MPT, EPT, and FT children, all with normal development upon school entry. STUDY DESIGN: Prospective cohort study. SUBJECTS: We included 1247 preterm (PT) children (gestational age [GA] 24.0-35.6 weeks) and 488 FT children (GA 38.0 41.6 weeks), with normal gross motor development at 4 years according to the Ages and Stages Questionnaire. OUTCOME MEASURES: We assessed 11 gross motor milestones assessed in preventive child healthcare during six standardized visits at calendar age. RESULTS: During the first six months, all PT categories had lower milestone attainment-rates than FTs children (differences 9-60% for PTs compared with FTs children). For all PT categories attainment rates gradually increased during toddlerhood. For PT children with higher GA, differences in attainment rates compared with FTs children were smaller and attainment rates became comparable to FT children at an earlier age. At age 24 months only attainment rates for PT children born <30 weeks GA remained lower than for FTs children (85% versus 95%, P < 0.01). CONCLUSION: Milestone attainment rates are highly dependent on GA during the first two years. Differences between PT and FT children are larger and persist longer with lower GA. For PT children <30 weeks GA, differences still occur at 24 months. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER: controlled-trials.com, ISRCTN 80622320.

AB - Self-assembly of nanoparticles into superlattices can be used to create hierarchically structured materials with tailored functions. We have used the surface sensitive quartz crystal microbalance with dissipation monitoring (QCM-D) technique in combination with video microscopy (VM) to obtain time-resolved information on the mass increase and rheological properties of evaporation induced self-assembly of nanocubes. We have recorded the frequency and dissipation shifts during growth and densification of superlattices formed by self-assembly of oleic acid capped, truncated iron oxide nanocubes and analyzed the time-resolved QCM-D data using a Kelvin-Voigt viscoelastic model. We show that the nanoparticles first assemble into solvent-containing arrays dominated by a viscous response followed by a solvent-releasing step that results in the formation of rigid and well-ordered superlattices. Our findings demonstrate that QCM-D can be successfully used to follow self-assembly and assist in the design of optimized routes to produce well-ordered superlattices. PMID- 29579560 TI - Term-equivalent functional brain maturational measures predict neurodevelopmental outcomes in premature infants. AB - BACKGROUND: Term equivalent age (TEA) brain MRI identifies preterm infants at risk for adverse neurodevelopmental outcomes. But some infants may experience neurodevelopmental impairments even in the absence of neuroimaging abnormalities. OBJECTIVE: Evaluate the association of TEA amplitude-integrated EEG (aEEG) measures with neurodevelopmental outcomes at 24-36 months corrected age. METHODS: We performed aEEG recordings and brain MRI at TEA (mean post-menstrual age of 39 (+/-2) weeks in a cohort of 60 preterm infants born at a mean gestational age of 26 (+/-2) weeks. Forty-four infants underwent Bayley Scales of Infant Development, 3rd Edition (BSID-III) testing at 24-36 months corrected age. Developmental delay was defined by a score greater than one standard deviation below the mean (<85) in any domain. An ROC curve was constructed and a value of SEF90 < 9.2, yielded the highest sensitivity and specificity for moderate/severe brain injury on MRI. The association between aEEG measures and neurodevelopmental outcomes was assessed using odds ratio, then adjusted for confounding variables using logistic regression. RESULTS: Infants with developmental delay in any domain had significantly lower values of SEF90. Absent cyclicity was more prevalent in infants with cognitive and motor delay. Both left and right SEF90 < 9.2 were associated with motor delay (OR left: 4.7(1.2-18.3), p = 0.02, OR right: 7.9 (1.8-34.5), p < 0.01). Left SEF90 and right SEF90 were associated with cognitive delay and language delay respectively. Absent cyclicity was associated with motor and cognitive delay (OR for motor delay: 5.8 (1.3-25.1), p = 0.01; OR for cognitive delay: 16.8 (3.1-91.8), p < 0.01). These associations remained significant after correcting for social risk index score and confounding variables. CONCLUSIONS: aEEG may be used at TEA as a new tool for risk stratification of infants at higher risk of poor neurodevelopmental outcomes. Therefore, a larger study is needed to validate these results in premature infants at low and high risk of brain injury. PMID- 29579562 TI - Modification in supercapacitive behavior of CoO-rGO composite thin film from exposure to ferri/ferrocyanide redox active couple. AB - Present work demonstrates enhanced supercapacitive performance of CoO-rGO electrode using redox electrolyte. The long range electrostatic force developed during deposition of CoO-rGO composite thin film orient the molecules into the hexagonal crystal structure. The incorporated CoO particles into rGO nano-sheets make the structure more porous for the intercalation of the electrolyte ions through the electrode material. Additionally, 0.025 M K3[Fe(CN)6] + 0.025 M K4[Fe(CN)6] redox couple into KOH electrolyte enhances the supercapacitive performance than bare KOH electrolyte. The maximum specific capacitance of 1005 F g-1 is observed due to the combined effect of K3[Fe(CN)6] and K4[Fe(CN)6] redox couple into KOH electrolyte. Also, energy density of 86.74 Wh kg-1 at power density of 3.54 kW kg-1 suggest potential application of CoO-rGO composite thin film in the development of high energy density supercapacitor based on redox active electrolyte. PMID- 29579563 TI - Photo-induced surface modification to improve the performance of lead sulfide quantum dot solar cell. AB - The solution-processed quantum dot (QD) solar cell technology has seen significant advancements in recent past to emerge as a potential contender for the next generation photovoltaic technology. In the development of high performance QD solar cell, the surface ligand chemistry has played the important role in controlling the doping type and doping density of QD solids. For instance, lead sulfide (PbS) QDs which is at the forefront of QD solar cell technology, can be made n-type or p-type respectively by using iodine or thiol as the surfactant. The advancements in surface ligand chemistry enable the formation of p-n homojunction of PbS QDs layers to attain high solar cell performances. It is shown here, however, that poor Fermi level alignment of thiol passivated p type PbS QD hole transport layer with the n-type PbS QD light absorbing layer has rendered the photovoltaic devices from realizing their full potential. Here we develop a control surface oxidation technique using facile ultraviolet ozone treatment to increase the p-doping density in a controlled fashion for the thiol passivated PbS QD layer. This subtle surface modification tunes the Fermi energy level of the hole transport layer to deeper values to facilitate the carrier extraction and voltage generation in photovoltaic devices. In photovoltaic devices, the ultraviolet ozone treatment resulted in the average gain of 18% in the power conversion efficiency with the highest recorded efficiency of 8.98%.

AB - In this work, a new kind of polyion complex (PIC) micelles with pH and reduction dual responsiveness was developed for effective intracellular drug delivery. The PIC micelles can be readily prepared by mixing a polycationic block polymer, methoxy poly(ethylene glycol)-b-poly(l-lysine) (mPEG-PLL), with a small molecule polyacid, 2, 2'-dithiodisuccinic acid (DTS) in aqueous media. The resultant PIC micelles are of uniform spherical shapes with hydrodynamic radii ranging from 65 to 75 nm based on different feeding ratios of mPEG-PLL and DTS. Interestingly, by using the small molecule polyacid DTS, the obtained PIC micelles show distinct pH responsive disintegration in acid solution. Meanwhile, the PIC micelles were also assessed to be reduction-responsive due to the presence of disulfide bond in DTS. In view of these stimuli-responsive properties, the potential use of this PIC micelle as smart drug carrier was then investigated. Doxorubicin (DOX), a cationic anticancer drug, was loaded into the PIC micelles with high efficiency. In vitro drug release studies revealed that release of DOX from the PIC micelles was suppressed in neutral solutions due to the stable electrostatic interactions between PIC micelles and DOX, but could be accelerated in acidic solutions or under high GSH condition. Furthermore, flow cytometry and confocal laser scanning microscopy (CLSM) studies indicated that the DOX-loaded PIC micelles could be effectively internalized by MCF-7 human breast cancer cells and release the loaded DOX in intracellular environment. Consequently, the DOX-loaded PIC micelles were capable of inhibiting the proliferation of C26 murine colon cancer and MCF-7 human breast cancer cells in high efficiency, showing similar IC50 values as free DOX. Thus, this biocompatible PIC micelle may be promising for intracellular drug delivery.

AB - A novel Z-scheme AgI/BiOBr hybrid photocatalyst was successfully synthesized by a solvothermal-precipitation method, and its photocatalytic activity was evaluated by the degradation of ciprofloxacin (CIP, a typical antibiotic). The crystallization, morphology, photo-response, surface structure and electrochemical properties of the as-obtained photocatalyst were characterized by XRD, XPS, SEM, TEM, BET, UV-Vis absorption spectroscopy and photoluminescence spectra (PL) measurements, respectively. The optimized AgI(20 wt%)/BiOBr composite exhibited a remarkable photocatalytic activity and a rapid degradation ability for CIP with a removal efficiency of 90.9% in 1 h, which was considerably better than those of pure BiOBr (58.6%) and pure AgI (4.6%) alone as well as their simple mixtures (31.4%) under the same conditions, suggesting an synergistic effect in the hybrid materials. Meanwhile, CIP was efficiently mineralized, as revealed by a total organic carbon (TOC) removal efficiency of ca. 90% within 2 h, which was further confirmed by the 3D EEMs measurement. The reactive species trapping and electron spin resonance (ESR) experiments demonstrated that O2-, h+ and OH all participated in the CIP photodegradation process. The photocatalytic mechanism of AgI/BiOBr composites could be rationally explained by considering the Z-scheme structure, resulting in the higher redox potential and more efficient separation of charge carriers. Moreover, the wider photo-response range induced by the photosensitization of AgI also contributed to the superior photocatalytic activity of the hybrid materials. This work reports a novel method for the facile preparation of Z-scheme AgI/BiOBr hybrid photocatalyst and provides an effective methodology for the mineralization of CIP.

AB - Platinum is the most commonly used dye-sensitized solar cell (DSSC) counter electrode (CE) due to its superior electrocatalytic activity and high transparency. However, the scarcity and high-cost of Pt restrict its practical application for the large-scale production of DSSCs. Herein, a facile approach for fabricating highly dispersed Co9S8 nanoparticles with small diameters in the range of 5-10 nm on the surface of carbon nanofibers (CNFs) via an electrospinning followed by calcination and hydrothermal reaction was developed. The composite material could be used as an efficient and low-cost Pt-free CE for DSSCs. The DSSC assembled with the prepared Co9S8/CNFs composite as a CE exhibited excellent electrocatalytic activity and a power conversion efficiency (PCE) of 8.37%, which is comparable to that of the DSSC with conventional thermally deposited Pt as the CE (8.50%). Therefore, the Co9S8/CNFs composite can be used as an efficient and low-cost promising alternative CE in DSSCs.

AB - BACKGROUND: Caring is recognized as the essence of nursing and the core of nursing practice while a positive professional identity can lead to personal, social and professional fulfillment. Analyzing caring characters and professional identity yields important indications for the improvement of teaching methods. This study aims to explore the graduate nursing students' professional identity and caring characters in China, and analyze their correlation. METHOD: A descriptive cross-sectional study was used to collect data from 216 graduate nursing students between January and February 2017 in China. RESULTS: Graduate nursing students perceived they possessed positive caring characters while their professional identity was at a low level. A significant positive correlation was found between the Nursing Caring Characters Assessment Tool and Professional Identity Scale for Nursing Students. CONCLUSION: Graduate nursing students' professional identity was not satisfactory and one strategy to improve this is to internalize caring into the education process. Nursing educators should focus more on the formation of the students' professional identity and caring as a contributing factor to it. PMID- 29579568 TI - Impact of a critical care postgraduate certificate course on nurses' self reported competence and confidence: A quasi-experimental study. AB - BACKGROUND: Postgraduate education is said to support the development of nurses' professional competence and confidence, essential to the delivery of safe and effective care. However, there is a shortness of empirical evidence to demonstrate an increase to nurses' self-reported confidence and competence on completion of critical care postgraduate certificate-level education. OBJECTIVES: To explore the impact of a critical care postgraduate certificate course on nurses' self-reported competence and confidence. To explore the psychometric properties and performance of the Critical Care Competence and Confidence Questionnaire. DESIGN: A quasi-experimental pre/post-test design. PARTICIPANTS: A total population sample of nurses completing a critical care postgraduate certificate course at an Australian University. METHODS: The Critical Care Competence and Confidence Questionnaire was developed for this study to measure nurses' self-reported competence and confidence at baseline and follow up. Descriptive and inferential statistics were used to explore sample characteristics and changes between baseline and follow-up. Reliability of the questionnaire was explored using Cronbach's Alpha and item-total correlations. RESULTS: There was a statistically significant increase in competence and confidence between baseline and follow-up across all questionnaire domains. Satisfactory reliability estimates were found for the questionnaire. CONCLUSIONS: Completion of a critical care postgraduate certificate course significantly increased nurses' perceived competence and confidence. The Critical Care Competence and Confidence Questionnaire was found to be psychometrically sound for measuring nurses' self-reported competence and confidence. PMID- 29579569 TI - Predictors of nurses' level of participation in student care: A multivariable analysis. AB - OBJECTIVE: To determine the association and predictive nature of certain socio demographic, education, work and research variables on nurses' participation level in the clinical care of students. DESIGN: A cross-sectional analytical study using a validated questionnaire between February and June 2014. SETTING AND PARTICIPANTS: A consecutive sample of 117 nurses who worked in public health centres in the province of Castellon (Spain) in 2014. The nurses who had never mentored students and the questionnaires that were <50% complete were excluded. METHODS: A descriptive analysis of the sample and an association analysis between variables were performed. The questionnaire and its dimensions were performed with a logistic regression and the maximum likelihood method, which used a complementary log-log link method. The concordance index was calculated using contingency tables. RESULTS: The mean age was 42.56 years, and the overall mean questionnaire score was 122.84 (SD = 18.69; 95% CI: 119.415-126.26). Across the sample, 58.1% (n = 68) of the nurses obtained an Excellent score, followed by Adequate in 41% (n = 48). Overall, the predictive variables were age, mentoring of students in the last 5 years and previous training to mentor students. CONCLUSION: The main predictive variable for greater participation in the mentorship of students was previous training in mentoring. This study also reflected on other variables that could influence nurses' participation in student mentoring. PMID- 29579570 TI - Nursing curriculum and bullying: An integrative literature review. AB - OBJECTIVES: The purpose of this integrative review was to identify and synthesize key concepts that inform curriculum which increase nursing students' competence, skills and strategies when addressing bullying. Specifically, the authors sought to examine the concepts informing educational interventions, skills, and strategies, which addressed the bullying of nursing students. DESIGN: Integrative literature review. DATA SOURCES: A search of the electronic databases CINAHL, MEDLINE, ERIC, PsycINFO, Proquest, and PubMed was conducted in January 2016 using search terms such as 'bully' 'nursing student' 'education' and 'curriculum'. REVIEW METHODS: Articles were screened for relevance and eligibility and extracted onto a table. Critical appraisal was conducted using multiple tools. Papers were analysed using constant comparison and concept mapping. RESULTS: 61 articles were included in the synthesis. Concepts identified included: empowerment, socialization, support, self-awareness, awareness about bullying, collaboration, communication, and self-efficacy. All concepts linked to empowerment. Social Cognitive Theory was used by many studies. Active teaching methods which gave students opportunities to practice skills were the most effective. CONCLUSIONS: Empowered nursing students have the potential to address bullying more effectively and competently. Empowerment of nursing students is a powerful concept that educators must consider when developing curriculum and educational interventions to address bullying. PMID- 29579571 TI - Identifying reliable predictors of protein-energy malnutrition in hospitalized frail older adults: A prospective longitudinal study. AB - BACKGROUND: Decreased food intake is a risk factor for relevant complications (e.g. infections, pressure ulcers), longer hospital stays, higher readmission rates, greater health care costs and increased patient mortality, particularly in frail hospitalized older adults who are malnourished or at risk of malnutrition. Nurses are called to improve this criticality, starting from accurately identifying malnourished patients at hospital admission and effectively monitoring their food intake. OBJECTIVES: The primary aim was to identify reliable predictive indicators of reduced food intake at hospital admission. The secondary aims were to assess the adequacy of daily energy and protein intake and the impact of nutrient intake on patient outcomes. DESIGN: Prospective observational longitudinal study. SETTING: Internal Medicine Ward of an Academic Teaching University Hospital. PARTICIPANTS: Acute older adults who were malnourished or at risk of malnutrition (Nutritional Risk Score-2002 >= 3, middle upper arm circumference <23.5 cm or impaired self-feeding ability) at admission. METHODS: The effective energy and protein intake was monitored during the first 5 days of hospital stay by a photographic method and compared to the daily energy and protein requirement calculated by specific equations. Data on anthropometry, inflammation/malnutrition laboratory data and body composition (phase angle calculated using bioelectrical impedance analysis) were collected. RESULTS: Eighty-one subjects (age 81.5 +/- 11.5 years) were enrolled. Mean energy intake was 669.0 +/- 573.9 kcal/day, and mean protein intake was 30.7 +/- 25.8 g/day. Over 60% of patients ingested <=50% of their calculated energy and protein requirements: these patients were older (p = 0.026), had a lower middle-upper arm circumference (p = 0.022) and total arm area (p = 0.038), a higher C-reactive protein/albumin ratio and Instant Nutritional Assessment score (p < 0.01), and experienced longer hospital stays (p <= 0.04) and higher in-hospital and 30-day post-discharge mortality (p < 0.001). In the multivariate analysis, lower middle upper arm circumference, higher C-reactive protein/albumin ratio, and impaired self-feeding at admission were independently associated with critically reduced energy and protein intake. CONCLUSIONS: Middle-upper arm circumference, C reactive protein/albumin ratio, and impaired self-feeding are easily obtainable indicators of impaired energy and protein intake and poor clinical outcomes. Such parameters should be adopted as screening criteria to assess the risk for critically reduced energy/protein intake in hospitalized older adults. These findings are relevant to improve clinical practice through the implementation of multidisciplinary strategies, given the adverse clinical outcomes related to hospital malnutrition. PMID- 29579572 TI - Impact of physician-less pediatric critical care transport: Making a decision on team composition. AB - PURPOSE: To explore the impact of a physician non-accompanying pediatric critical care transport program, and to identify factors associated with the selection of specific transport team compositions. MATERIALS AND METHODS: Children transported to a Canadian academic children's hospital were included. Two eras (Physician accompanying Transport (PT)-era: 2000-07 when physicians commonly accompanied the transport team; and Physician-Less Transport (PLT)-era: 2010-15 when a physician non-accompanying team was increasingly used) were compared with respect to transport and PICU outcomes. Transport and patient characteristics for the PLT era cohort were examined to identify factors associated with the selection of a physician accompanying team, with multivariable logistic regression with triage physicians as random effects. RESULTS: In the PLT-era (N=1177), compared to the PT-era (N=1490) the probability of PICU admission was significantly lower, and patient outcomes including mortality were not significantly different. Associations were noted between the selection of a physician non-accompanying team and specific transport characteristics. There was appreciable variability among the triage physicians for the selection of a physician non-accompanying team. CONCLUSIONS: No significant differences were observed with increasing use of a physician non-accompanying team. Selection of transport team compositions was influenced by clinical and system factors, but appreciable variation still remained among triage physicians. PMID- 29579573 TI - Cardiovascular ultrasonography detection of embolic sources in trauma. AB - Venous thromboembolism (deep vein thrombosis and pulmonary embolism) and bone cement implantation syndrome are major sources of embolic events in trauma patients. In these patients, embolic events due to venous thromboembolism and bone cement implantation syndrome have been detected with cardiac and vascular ultrasonography in the emergency setting, during the perioperative period, and in the intensive care unit. This article discusses the ultrasonography modalities and imaging findings of embolic events related to venous thromboembolism and bone cement implantation syndrome. The aim is to present a short review with exceptional illustrations that can enable physicians to identify sources of emboli in trauma patients with cardiovascular ultrasonography.

AB - A substantial portion of the genomes of most multicellular eukaryotes consists of large arrays of tandemly repeated sequence, collectively called satellite DNA. The processes generating and maintaining different satellite DNA abundances across lineages are important to understand as satellites have been linked to chromosome mis-segregation, disease phenotypes, and reproductive isolation between species. While much theory has been developed to describe satellite evolution, empirical tests of these models have fallen short because of the challenges in assessing satellite repeat regions of the genome. Advances in computational tools and sequencing technologies now enable identification and quantification of satellite sequences genome-wide. Here, we describe some of these tools and how their applications are furthering our knowledge of satellite evolution and function.

AB - Bacterial volatile compounds (BVCs) are not waste or by-products of primary metabolism but rather have critical roles in the biology and ecological competence of bacteria. BVCs are exploited as a source of nutrients and information in plant-bacteria interactions. They target key points in plant physiology, activating downstream metabolic pathways by a domino effect. BVCs are an ancient signal and are involved in plant-bacteria communication, which was shaped during evolutionary history and established before the development of higher plants. This type of communication is not exclusive to mutualistic interactions, because pathogens also use volatiles to alter plant physiology. Here, fragmented information is drawn together to provide a clearer view of how BVCs affect such interactions. PMID- 29579578 TI - The molecular machines that traffic signaling receptors into and out of cilia. AB - Cilia are surface-exposed organelles that dynamically concentrate signaling molecules to organize sensory, developmental and homeostatic pathways. Entry and exit of signaling receptors is germane to the processing of signals and the molecular machines for entry and exit have started to emerge. The IFT-A complex and its membrane recruitment factor Tulp3 complex promotes the entry of signaling receptors into cilia while the BBSome and its membrane recruitment factor Arl6GTP ferry activated signaling receptors out of cilia. Ciliary exit is a surprisingly complex process entailing passage through a first diffusion barrier at the transition zone, diffusion inside an intermediate compartment and crossing of a periciliary diffusion barrier. The two barriers may organize a privileged compartment where activated signaling receptors transiently reside. PMID- 29579580 TI - Cost-effectiveness of a management strategy based on exercise echocardiography versus exercise electrocardiography in patients presenting with suspected angina during long term follow up: A randomized study. AB - INTRODUCTION: Exercise ECG (Ex-ECG) is advocated by guidelines for patients with low - intermediate probability of coronary artery disease (CAD). However, there are no randomized studies comparing Ex-ECG with exercise stress echocardiography (ESE) evaluating long term cost-effectiveness of each management strategy. METHODS: Accordingly, 385 patients with no prior CAD and low-intermediate probability of CAD (mean pre-test probability 34%), were randomized to undergo either Ex-ECG (194 patients) or ESE (191 patients). The primary endpoint was clinical effectiveness defined as the positive predictive value (PPV) for the detection of CAD of each test. Cost-effectiveness was derived using the cumulative costs incurred by each diagnostic strategy during a mean of follow up of 3.0 years. RESULTS: The PPV of ESE and Ex-ECG were 100% and 64% (p = 0.04) respectively for the detection of CAD. There were fewer clinic (31 vs 59, p < 0.01) and emergency visits (14 vs 30, p = 0.01) and lower number of hospital bed days (8 vs 29, p < 0.01) in the ESE arm, with fewer patients undergoing coronary angiography (13.4% vs 6.3%, p = 0.02). The overall cumulative mean costs per patient were L796 for Ex-ECG and L631 for ESE respectively (p = 0.04) equating to a >20% reduction in cost with an ESE strategy with no difference in the combined end-point of death, myocardial infarction, unplanned revascularization and hospitalization for chest pain between ESE and Ex-ECG (3.2% vs 3.7%, p = 0.38). CONCLUSION: In patients with low to intermediate pretest probability of CAD and suspected angina, an ESE management strategy is cost-effective when compared with Ex-ECG during long term follow up. PMID- 29579579 TI - Deciphering functional glycosaminoglycan motifs in development. AB - Glycosaminoglycans (GAGs) such as heparan sulfate, chondroitin/dermatan sulfate, and keratan sulfate are linear glycans, which when attached to protein backbones form proteoglycans. GAGs are essential components of the extracellular space in metazoans. Extensive modifications of the glycans such as sulfation, deacetylation and epimerization create structural GAG motifs. These motifs regulate protein-protein interactions and are thereby repsonsible for many of the essential functions of GAGs. This review focusses on recent genetic approaches to characterize GAG motifs and their function in defined signaling pathways during development. We discuss a coding approach for GAGs that would enable computational analyses of GAG sequences such as alignments and the computation of position weight matrices to describe GAG motifs. PMID- 29579581 TI - Midazolam addition to analgosedation for pulmonary vein isolation may increase risk of hypercapnia and acidosis. AB - BACKGROUND: Pulmonary vein isolation (PVI) is generally performed under analgosedation, but sedation protocols vary and no optimal protocol has been defined. We investigated procedural, respiratory and hemodynamic parameters in patients undergoing PVI using analgosedation either with or without midazolam. METHODS: In a prospective observational study, we compared n = 43 consecutive patients (54% male, mean age 62 years) undergoing PVI using analgosedation either with or without midazolam added to propofol and fentanyl. A priori defined outcome measures were propofol dose, hypotension (systolic blood pressure <100 mm Hg or >30 mm Hg drop from baseline), acidosis (pH < 7.30), hypercapnia (pC02 > 55 mm Hg) and hypoxemia (transdermal oxygen saturation < 90%). RESULTS: Patients in the midazolam group (n = 22) received a mean dose of 3 +/- 1.5 mg midazolam and required less propofol than those in the no-midazolam group (n = 21, 473 +/- 189 mg vs. 618 +/- 219 mg, p = .03). Incidence of hypotension did not differ between groups (54.5% vs. 61.9%, p = .63). Acidosis was more frequent in the midazolam group (63.6% vs. 28.6%, p = .03), as was hypercapnia (50% vs. 14.3%, p = .03) while occurrence of hypoxemia did not differ between groups (22.7 vs. 33.3%, p = .5). CONCLUSION: Patients receiving midazolam had a more than doubled risk of respiratory depression as mirrored by hypercapnia and acidosis, but not hypoxemia. These observations may help in choosing an analgosedation and monitoring protocol for PVI.

PMID- 29579585 TI - Resting heart rate in late adolescence and long term risk of cardiovascular disease in Swedish men. AB - AIM: To investigate the association of resting heart rate (RHR) measured in late adolescence with the long term risk of myocardial infarction (MI), ischemic stroke (IS), heart failure (HF), atrial fibrillation (AF), cardiovascular- and all-cause death. METHODS AND RESULTS: We followed a cohort of Swedish men enrolled for conscription in 1968-2005 (n = 1,008,485; mean age = 18.3 years) until December 2014. Outcomes were collected from the national inpatient - (IPR), outpatient - (OPR) and cause of death registries. Cox proportional hazard models were used to analyze the longitudinal association between RHR and outcomes while adjusting for potential confounders. While we found no independent association between RHR and risk of IS or MI when comparing the highest with the lowest quintile of the RHR distribution, but a positive association persisted between RHR and incident HF (Hazard ratio (HR) = 1.39 [95% confidence interval (CI) = 1.29-1.49]) after adjustment for body mass index (BMI) and blood pressure (BP). In similarly adjusted models, an inverse association was found for AF while there were weaker associations with death from cardiovascular disease (CVD) and all causes (adjusted HR = 1.12 [CI = 1.04-1.21] and 1.20 [CI = 1.17-1.24]). After further adjustment for cardiorespiratory fitness (CRF), the associations persisted for HF (HR = 1.26 [1.17-1.35] for any diagnostic position and HR = 1.43 [1.28-1.60] for HF as a main diagnosis) and for all-cause death (HR 1.09 [1.05 1.12]) but not for CVD death. CONCLUSION: Adolescent RHR is associated with future risk of HF and death, independently of BP, BMI and CRF, but not with CVD death, MI or IS, suggesting a causal pathway between elevated heart rate and myocardial dysfunction. PMID- 29579586 TI - Subclinical left ventricular dysfunction and correlation with regional strain analysis in myocarditis with normal ejection fraction. A new diagnostic criterion. AB - BACKGROUND: The diagnosis of myocarditis is challenging, especially in case of normal left ventricular systolic function. The aim of this study is to test the hypothesis that 2D speckle tracking echocardiography (2DSTE) can detect subclinical left ventricular (LV) dysfunction in patients with myocarditis and preserved LV function without regional wall motion abnormalities and that regional strain analysis can correlate with cardiac magnetic resonance (CMR) findings. METHODS: Study population consisted of 25 consecutive patients with myocarditis and 19 controls. All patients underwent a full echocardiographic study at the first day of their admission and in addition to conventional echocardiographic measurements, global longitudinal and circumferential strain of the left ventricle (LVGLS, LVCS accordingly), as well as regional strains of the lateral wall, were estimated. Moreover, all patients underwent a CMR scan during the first week from their admission. RESULTS: Although there was no statistical difference between the two groups of patients in systolic function, myocarditis patients demonstrated significantly impaired LVGLS (-16.5 +/- 2.2 vs -20.5 +/- 1.3%, p < 0.0001) and LVCS (-16.4 +/- 3.7 vs -20.9 +/- 2%, p = 0.002), as well as segmental longitudinal strains of the lateral wall. CMR in all myocarditis patients revealed late gadolinium enhancement in the lateral left ventricle free wall. CONCLUSIONS: In patients with acute myocarditis with preserved ejection fraction, 2DSTE evaluation appears to be a promising, useful noninvasive and inexpensive tool in addition to existing methods used for the diagnosis of acute myocarditis, since it seems to be able to identify myocardial fibrosis early in the setting of the disease. PMID- 29579587 TI - A systematic review of clozapine-induced myocarditis. AB - BACKGROUND: Clozapine is an atypical antipsychotic that is beneficial to some patients who failed to have an adequate clinical response to other antipsychotic drugs. Its clinical use is limited due to several potentially fatal adverse reactions including myocarditis. Careful monitoring of patients on clozapine is required. METHODS: We conducted a systematic review of the literature on myocarditis associated with clozapine therapy. The search engines used to identify cases were MEDLINE, EMBASE, PsycINFO and Cochrane reviews. The references included in the manuscripts reviewed were searched to identify additional reports. RESULTS: We identified a total of 3347 articles that addressed the cardiac complications of clozapine. Of these, 82 articles detailed cases of clozapine-induced myocarditis. The median age of patients and dose of clozapine at presentation was 30years and 250mg/day respectively. Symptoms and signs of myocarditis developed in 87% of patients within the first month of treatment. Clinical presentation included: shortness of breath (67%), fever (67%) and tachycardia (58%). Cardiac markers were elevated in 87% of the 54 cases that reported these markers. Global ventricular dysfunction was the predominant echocardiogram finding (57%). CONCLUSIONS: Patients on clozapine require routine monitoring for symptoms and signs of myocarditis during the first three months of therapy. This adverse drug reaction is difficult to diagnose due the non-specific nature of the symptoms and signs. Alternate causes of myocarditis should be ruled out before attributing the myocarditis to clozapine. PMID- 29579588 TI - Clozapine-induced myocarditis: "Psychoanalysing" drug-induced myocarditis.

AB - BACKGROUND: The AMP-activated protein kinase (AMPK) plays critical roles in growth regulation and metabolism reprogramming. AMPK activation protects cells against apoptosis from injury in different cell and animal models. However, its function in necroptosis remains largely unclear. METHODS AND RESULTS: In the current study, we demonstrated that AMPK was activated upon necroptosis induction and protected mouse embryonic fibroblasts (MEFs) and cardiomyocytes from N-methyl N'-nitro-N-nitrosoguanidine (MNNG) and reactive oxygen species (ROS) induced necroptosis. Activation of AMPK with chemicals A-769662, 2-deoxyglucose (2-DG), and metformin or constitutively active (CA) AMPK markedly decreased necroptosis and cytotoxicity induced by MNNG. In contrast, AMPK inhibitor compound C, dominant negative (DN) AMPK, as well as AMPK shRNAs increased necroptosis and cytotoxicity induced by MNNG. We further showed that AMPK physically associated with a protein complex containing PGAM5 and Keap1 whereby facilitating Keap1 mediated PGAM5 ubiquitination upon necroptosis induction. The AMPK agonist metformin ameliorated myocardial ischemia and reperfusion (IR) injury and reduced necroptosis through down-regulating the expression of PGAM5 in the Langendorff perfused rat hearts. CONCLUSION: Activation of AMPK protects against necroptosis via promoting Keap1-mediated PGAM5 degradation. Metformin may act as a valuable agent for the protection of myocardial ischemia and reperfusion injury by activating AMPK and reducing necroptosis.

PMID- 29579597 TI - Physiological insights of exercise hyperventilation in arterial and chronic thromboembolic pulmonary hypertension. AB - BACKGROUND: Pulmonary hypertension (PH) patients show, during exercise, an excessive increase in ventilation (VE) compared to carbon dioxide output (VCO2), determining a high VE/VCO2 slope. There are several possible causes, including an elevated dead space ventilation (VD), VE/perfusion (Q) mismatch and/or an enhanced peripheral or central chemoreceptor activity. We evaluated the causes of exercise hyperventilation in PH patients. METHODS: Eighteen group I and IV PH patients underwent cardiopulmonary exercise test with blood gas analysis at every minute. VE, alveolar ventilation (VA) and VD vs. VCO2 relationship were calculated. Resting chemoreceptor sensitivity was analyzed through hypoxia/hypercapnia tests. RESULTS: PeakVO2 and VE/VCO2 slopes were 1.06+/ 0.24l/min and 39.1+/-9.0, respectively. Throughout the exercise, 30% of VE was due to VD. VE/VCO2 slope significantly correlated with VD/VCO2 slope (r=0.82, p<0.001) but not with VA/VCO2 slope (r=0.3, p=ns). Peak exercise end-tidal CO2 (PetCO2) correlated with VD/VCO2 slope (r=-0.79, p<0.001) and VE/VCO2 slope (r= 0.91, p<0.001). Dead space(DS)/Tidal volume and P(arterial-et)CO2 were elevated without arterial hypoxemia suggesting a high VE/Q mismatch. Chemoreceptor peripheral response to hypoxia and central CO2 response were both enhanced being peripheral responses to hypoxia and hypercapnia 0.416+/-0.402 (normal ref values=0.285+/-0.221) l/min/O2Sat and 0.076+/-0.047 (0.066+/-0.430) l/min/mmHg, respectively; central hypercapnic chemosensitivity was 4.475+/-3.99 (2.352+/ 0.936) l/min/mmHg. CONCLUSIONS: Increased DS, VE/Q mismatch and chemorecptor response are among the main mechanisms involved in exercise hyperventilation in PH. ClinicalTrial.govNCT02892981.

AB - BACKGROUND: Biomarkers to predict the presence and severity of subclinical cardiovascular disease (CVD) in nonalcoholic fatty liver disease (NAFLD) are lacking. METHODS: 3876 participants from the Multi-Ethnic Study of Atherosclerosis (MESA), without known chronic liver disease underwent baseline non-contrast cardiac CT, with NAFLD defined by validated liver:spleen ratio (L:S) < 1.0, and subclinical CVD defined by coronary artery calcium (CAC) score > 0. Randomly-selected subgroups underwent detailed inflammatory marker testing, including LpPLA2 mass (N = 2951), activity (N = 3020), high-sensitivity C reactive protein (hsCRP; N = 3849), and interleukin-6 (IL-6; N = 3764). Among those with NAFLD, we estimated the prevalence of CAC > 0 and CAC > 100 for each SD biomarker increase, using multivariable log-binomial regression models adjusted for cardiometabolic risk factors. RESULTS: Seventeen percent (N = 668) of participants met the criteria for NAFLD. NAFLD participants were younger (mean age 61 +/- 10 vs. 63 +/- 10 years, p < .0001) but more likely to have an elevated BMI (mean 31.1 +/- 5.5 vs. 28.0 +/- 5.2 kg/m2, p < .0001), diabetes (22% vs. 11%, p < .0001), and increased inflammatory biomarkers, including LpPLA2 activity, hsCRP and IL-6 (all p < .0001). Among NAFLD participants, IL-6 was the only biomarker independently associated with prevalent CAC > 0 (PR = 1.06 [1.00 1.11]), or CAC > 100 (PR = 1.09 [1.02-1.17]). In contrast, circulating LpPLA2 mass/activity and hsCRP were not associated with either the prevalence or severity of subclinical CVD (all p > .05). CONCLUSION: In a large, multi-ethnic population with NAFLD, IL-6 is independently associated with the prevalence and severity of subclinical atherosclerosis. Further research into the longitudinal effects of NAFLD on progressive CVD will determine whether IL-6 is a marker or mediator of NAFLD-related atherosclerosis. PMID- 29579602 TI - High on-treatment platelet reactivity and outcome in elderly with non ST-segment elevation acute coronary syndrome - Insight from the GEPRESS study. AB - BACKGROUND: Elderly treated with dual antiplatelet therapy after percutaneous coronary intervention (PCI) represent a challenging population because of increased risk of both ischemic and bleeding events. We aimed to investigate the association between high on-treatment platelet reactivity (HPR) and long-term outcome in elderly with non-ST-elevated acute coronary syndromes (NSTE-ACS) undergoing PCI. METHODS: Platelet reactivity was measured by vasodilator stimulated phosphoprotein (VASP) assay at three time-points (baseline, discharge, 1 month after PCI) in 1053 NSTE-ACS patients (311 elderly) treated with clopidogrel. Major adverse cardiac events (MACE) were assessed up to 1 year follow-up. RESULTS: Elderly with HPR at discharge showed a significantly higher incidence of overall MACE (13 vs 4%, p = .006), cardiac death (6 vs 0.7%, p = .020), myocardial infarction (MI, 12 vs 4%, p = .031) and a trend for higher stent-thrombosis (5 vs 0.7%, p = .068). Similarly, elderly with 1-month-HPR showed between 1 month and 1 year significantly higher incidence of MACE (10 vs 4%, p = .012), cardiac death (6 vs 0.7%, p = .019) and composite cardiac death/MI (11 vs 4%, p = .014). Up to 1 year, elderly with HPR showed a 4-fold increased risk of MACE compared to both elderly without HPR (for discharge-HPR: p = .005; for 1-month-HPR: p = .01) and non-elderly with HPR (for discharge-HPR: p < .001; for 1-month-HPR: p < .0001). At multivariable analysis, HPR could independently predict 1-year-MACE in elderly (for discharge-HPR: HR = 3.191, CI: 1.373-7.417, p = .007; for 1-month-HPR: HR = 3.542, CI: 1.373-9.137, p = .009). CONCLUSIONS: In elderly with NSTE-ACS undergoing PCI and treated with clopidogrel, HPR was independently associated with an increased risk of MACE up to 1 year.

PMID- 29579607 TI - Development and validation of Women Acute Myocardial Infarction in-Hospital Mortality Score (WAMI Score). AB - BACKGROUND: A variety of risk models have been developed to predict acute myocardial infarction (AMI) in-hospital mortality risk. As a distinct, higher risk population, women with AMI have different risk profiles from their men counterparts. Published researches have indicated that the interaction between variables in these models for in-hospital mortality and gender are significant. Due to the interaction and gender differences, the predicting value of these risk models for women could be controversial. METHODS: Databases from the China Patient-centered Evaluative Assessment of Cardiac Events (China PEACE) Retrospective AMI Study were utilized for model derivation (n=16,100, women were 4896) and databases from the China PEACE Prospective AMI Study for model validation (n=6207, women were 2090). A multivariable backward stepwise logistic regression was used to examine correlates of in-hospital mortality, and the variables were subsequently weighted and integrated into a scoring system. RESULTS: We constructed a novel risk-predicting tool to estimate the baseline risk of in-hospital mortality among women with AMI. The risk score includes 8 variables [age, systolic blood pressure, heart rate, initial glomerular filtration rate (GFR), serum glucose, Killip class, cardiac arrest, ventricular tachycardia/ventricular fibrillation (VT/VF)]. The prognostic discriminatory capacity of the Women Acute Myocardial Infarction in-Hospital Mortality (WAMI) risk score was excellent (c statistic 0.84, 95% confidence interval [CI]: 0.83 to 0.86, p<0.001). External validation of the model showed better prognostic capacity (c statistic 0.87, 95% CI: 0.84 to 0.90, p<0.001) than the GRACE risk score (0.77, 95% CI 0.72-0.82, p<0.001) and TIMI risk score (0.72, 95% CI 0.68 0.77, p<0.001). CONCLUSIONS: The WAMI Score is a simple robust tool for predicting the in-hospital mortality risk of women with AMI.

PMID- 29579615 TI - Second-generation cryoballoon ablation as a first-line treatment of symptomatic atrial fibrillation: Two-year outcome and predictors of recurrence after a single procedure. AB - INTRODUCTION: Antiarrhythmic drug (AAD) therapy of patients with atrial fibrillation (AF) has limitations. We investigated the 2-year outcome and pre procedural predictors of recurrence for first-line catheter ablation using the second-generation cryoballoon (CB-Adv) in a large cohort of patients with symptomatic AF. METHODS AND RESULTS: For this prospective observational study, we enrolled 457 patients with symptomatic AF (278 paroxysmal, 179 persistent) who had no history of AAD use and who underwent pulmonary vein isolation (PVI) with the CB-Adv at our institution. Follow-up data, including Holter-ECGs, were collected during outpatient clinic visits. The impact of several variables on outcome was evaluated in univariate and multivariate analyses and Cox proportional hazards regression models. Median follow-up duration was 28 (interquartile range 15/42) months. PVI was sufficient in restoring and maintaining sinus rhythm in 79.2% (n=362) of patients. The median procedure and fluoroscopy times were 90 (72/120) and 16 (12/21) min, respectively. Phrenic nerve injury occurred in 16 (3.5%) patients, persisting until hospital discharge in 6 (1.3%) patients; phrenic nerve function recovered in all patients during follow-up. Seven patients developed groin hematomas (1.5%). Cox regression analysis showed that left atrial area >21cm2 independently predicted recurrence. CONCLUSION: This is the first demonstration that PVI with CB-Adv is safe and effective as a first-line treatment of symptomatic AF. Sinus rhythm persisted in 79.2% of patients even 2years after ablation. The success rate was lower in patients with enlarged left atria. PMID- 29579616 TI - Impact of prophylactic cavotricuspid isthmus ablation in atrial fibrillation recurrence after a first pulmonary vein isolation procedure. AB - INTRODUCTION: PVI is a well-established therapy for patients with drug refractory atrial fibrillation (AF). However, it remains unclear whether prophylactic cavotricuspid isthmus (CTI) ablation at the time of PVI improves long-term freedom from AF. OBJECTIVE: To compare the outcomes of patients who underwent PVI alone vs. PVI + prophylactic CTI ablation. METHODS: Propensity score (PS) matching analysis based on a registry dataset of 1931 consecutive patients who underwent a first AF catheter ablation. After excluding those with documented/inducible atrial flutter (n = 233), 1698 individuals were available for matching. Following adjustment for age, gender, body mass index (BMI), hypertension, smoking, diabetes, LA volume, type of AF, and type of navigation (magnetic vs. manual), PS matched 411 patients who underwent PVI + CTI ablation with 411 receiving PVI alone. RESULTS: PS analysis yielded a study population of 822 matched patients (58 +/- 11 years, 69% males, 64% with paroxysmal AF). Over a median 2 years follow-up period there were 278 AF recurrences (34%). Survival free of AF (Log rank p = .965) and annual relapse rates were similar in the two groups - 10.9%/year vs 10.1%/year (PVI vs PVI + CTI, respectively, p = .97). CTI ablation remained unassociated with AF-free survival (HR 1.09, 95%CI: 0.84-1.41, p = .54) after Cox regression adjustment for age, sex, type of AF, LA volume, hypertension, diabetes, BMI and center. Female gender, current smoking, indexed LA volume and non-paroxysmal AF were identified as independent predictors of relapse after matching. CONCLUSIONS: Prophylactic CTI ablation at the time of a first PVI does not seem to improve long-term freedom from AF. PMID- 29579618 TI - Fluorescence-guided surgery of cancer: applications, tools and perspectives. AB - Thousands of patients die each year from residual cancer that remains following cytoreductive surgery. Use of tumor-targeted fluorescent dyes (TTFDs) to illuminate undetected malignant tissue and thereby facilitate its surgical resection shows promise for reducing morbidity and mortality associated with unresected malignant disease. TTFDs can also improve i) detection of recurrent malignant lesions, ii) differentiation of normal from malignant lymph nodes, iii) accurate staging of cancer patients, iv) detection of tumors during robotic/endoscopic surgery (where tumor palpation is no longer possible), and v) preservation of healthy tissue during resection of cancer tissue. Although TTFDs that passively accumulate in a tumor mass provide some tumor contrast, the most encouraging TTFDs in human clinical trials are either enzyme-activated or ligand targeted to tumor-specific receptors. PMID- 29579617 TI - Benefits of left ventricular endocardial pacing comparing failed implants and prior non-responders to conventional cardiac resynchronization therapy: A subanalysis from the ALSYNC study. AB - OBJECTIVE: Cardiac resynchronisation therapy (CRT) is limited by a substantial proportion of non-responders. Left ventricular endocardial pacing (LVEP) may offer enhanced possibility to deliver CRT in patients with a failed attempt at implantation and to improve clinical status of CRT non-responders. METHODS: The ALternate Site Cardiac ResYNChronisation (ALSYNC) study was a prospective, multi centre cohort study that included 118 CRT patients with a successfully implanted endocardial left ventricular (LV) lead, including 90 failed coronary sinus (CS) implants and 28 prior non-responders who had worsened or unchanged heart failure status after at least 6 months of optimal conventional CRT therapy. RESULTS: Patients were followed for 19 +/- 9 months. At baseline, prior non-responders were sicker as evidenced by a larger LV end-diastolic diameter (70 +/- 12 vs 65 +/- 9 mm, p = .03) and a trend towards larger LV end-systolic volume index (LVESVi, 95 +/- 51 vs 74 +/- 39 ml/m2, p = .07), and were more frequently anti coagulated (96% vs 72%, p = .008) despite similar history of atrial fibrillation (54% vs 51%, p = .83). At 6 months, LVEP significantly improved LV ejection fraction (2.3 +/- 7.5 and 8.6 +/- 10.0%), New York Heart Association Class (0.4 +/- 0.9 and 0.7 +/- 0.8), LVESVi (9 +/- 16 and 18 +/- 43 ml/m2), and six-minute walk test (56 +/- 73 and 54 +/- 92 m) in prior non-responders and failed CS implants, relative to baseline (all p < .05), respectively. LVESVi reduction >=15% was seen in 47% of the prior non-responder patients and 57% of failed CS patients. CONCLUSION: These data suggest that a sizable proportion of CRT non responders can improve by LVEP, though to a lesser extent than failed CS implants.

AB - DNA and histone methylation belong to the key regulatory components in the epigenetic machinery, and dysregulations of these processes have been associated with various human diseases. Small molecule modulators of these epigenetic targets are highly valuable both as chemical probes to study the biological roles of the target proteins, and as potential therapeutics. Indeed, recent years have seen the discovery of chemical modulators of several epigenetic targets, some of which are already marketed drugs or undergoing clinical trials. In this review, we will focus on small molecule modulators of DNA and histone methylation. PMID- 29579620 TI - Ground reaction forces during a drop vertical jump: Impact of external load training. AB - External load training (ELT) is a supplemental training method used to potentially improve high intensity task performance. However, biomechanical parameters such as ground reaction forces (GRF), ground contact time, and time to peak GRF during a drop vertical jump (DVJ) following an ELT intervention have yet to be examined. Therefore, this study investigated the impact of ELT on certain biomechanical parameters of a DVJ task. Well-trained females stratified into two groups (ELT = 9, Control = 10) completed a DVJ from a 45.72 cm box onto a force platform at baseline, post-ELT, and post-detraining (DET). ELT consisted of wearing weight vests (WV) with 8% body mass for 32 h/week during daily living and 3 training sessions/week for 3 weeks. After ELT, a 3 week DET phase was completed. The control group replicated procedures without ELT intervention. The vertical, medial/lateral, and anterior/posterior components of the GRF were assessed during the initial contact, minimum force following initial contact, push-off, and second landing periods. Dependent variables were analyzed using a 2 (group) * 3 (time) mixed model ANOVA (p < .05). Significantly greater peak vertical GRF during the initial contact period was identified for the ELT group. Significant increases in the minimum vertical GRF following the initial contact period from baseline to post-ELT following the were observed for the ELT group, while significant increases in peak vertical GRF during the second landing period at post-ELT and post-DET in comparison to baseline was observed for both groups. The combination of greater vertical GRF during the initial contact period and the period following initial contact suggests that ELT may increase GRFs during a DVJ in comparison to routine training without a weighted vest. PMID- 29579621 TI - The effects of dual tasking on gait synchronization during over-ground side-by side walking. AB - Recent studies have shown that gait synchronization during natural walking is not merely anecdotal, but it is a repeatable phenomenon that is quantifiable and is apparently related to available sensory feedback modalities. However, the mechanisms underlying this phase-locking of gait have only recently begun to be investigated. For example, it is not known what role, if any, attention plays. We employed a dual tasking paradigm in order to investigate the role attention plays in gait synchronization. Sixteen pairs of subjects walked under six conditions that manipulated the available sensory feedback and the degree of difficulty of the dual task, i.e., the attention. Movement was quantified using a trunk-mounted tri-axial accelerometer. A gait synchronization index (GSI) was calculated in order to quantify the degree of synchronization of the gait pattern. A simple dual task resulted in an increased level of synchronization, whereas a more complex dual task lead to a reduction in synchronization. Handholding increased synchronization, compared to the same attention condition without handholding. These results indicate that in order for two walkers to synchronize, some level of attention is apparently required, such that a relatively complex dual task utilizes enough attentional resources to reduce the occurrence of synchronization. PMID- 29579622 TI - Engineering T cells for adoptive therapy: outsmarting the tumor. AB - Adoptive transfer of T cells gene-engineered with antigen-specific receptors, whether it be chimeric antigen receptors (CARs) or T cell receptors (TCRs), has proven its feasibility and therapeutic potential in the treatment of tumors. Despite clinical successes, the majority of patients experiences no or non sustainable clearance of solid tumors, which is attributed to local T cell evasive mechanisms. A rapidly expanding understanding of molecular and cellular events that contribute to a reduction in numbers and/or activation of intra-tumor T cells has facilitated the development of gene-engineering strategies, enabling T cells to counter immune tolerance. Here, we present an overview of gene engineering approaches and considerations to improve tumor-selectivity and effectiveness of adoptively transferred T cells. PMID- 29579623 TI - Chemokines and cancer: new immune checkpoints for cancer therapy. AB - The current review focuses on two chemokine-chemokine receptor interactions: CXCL10-CXCR3 and CCL1-CCR8. We show that CXCL10 acts on CD4+ and CD8+ T cells to enhance anti-tumor immunity, and explore the translational perspectives of these findings. As for CCR8 very recently, we identified a novel subset of CCR8+CD4+FOXp3+ regulatory T cells (Treg) that are major drivers of immune regulation. We observed that one of the four CCR8 ligands, CCL1, produced by these cells, potentiates their suppressive activity via induction of CCR8, FOXp3, CD39, Granzyme-B, and IL-10 in a positive feedback mechanism, making them master drivers of immune regulation. Collectively, this suggests blocking the CCR8-CCL1 interaction, alone or combined with other immune checkpoint inhibitors, as an approach to treat malignant diseases. PMID- 29579624 TI - Modulating ion channel function with antibodies and nanobodies. AB - Immune cells express various voltage-gated and ligand-gated ion channels that mediate the influx and efflux of charged ions across the plasma membrane, thereby controlling the membrane potential and mediating intracellular signal transduction pathways. These channels thus present potential targets for experimental modulation of immune responses and for therapeutic interventions in immune disease. Small molecule drugs and natural toxins acting on ion channels have illustrated the potential therapeutic benefit of targeting ion channels on immune cells. Unwanted side effects and immunogenicity have however hampered the application of these molecules. Owing to their high specificity, low immunogenicity and beneficial pharmacodynamics, antibodies targeting membrane and secretory proteins have emerged as potent therapeutics in oncology and inflammation. Nanobodies-single domain fragments derived from heavy chain antibodies naturally occurring in camelids-offer additional benefits versus antibodies, including protrusion into cryptic epitopes and easy formatting of multi-specific reagents. Here we review recent progress in the development and application of antibodies and Nanobodies targeting ion channels on immune cells. PMID- 29579625 TI - Course of bipolar illness worsens after onset of insulin resistance. AB - Cross-sectional studies indicate that comorbid insulin resistance (IR) and type 2 diabetes are associated with a more severe course of bipolar disorder (BD); however, this relationship has not previously been assessed longitudinally. To address this, we reviewed health records of a case series of six patients with BD and comorbid IR. Severity and length of affective episodes (both mania and depression) over the lifetime were recorded using the Affective Morbidity Index; these data were obtained from ongoing prospective follow-up and from detailed retrospective chart reviews. All six patients with a previously episodic, relapsing-remitting course of illness experienced a worsening of morbidity after the onset of laboratory-demonstrated IR. These results suggest that IR may be a potential testable, modifiable factor in the progression of BD from a treatment responsive (episodic) to a non-responsive (chronic) course of illness. PMID- 29579626 TI - Applications of genetically engineered human pluripotent stem cell reporters in cardiac stem cell biology. AB - The advent of human pluripotent stem cells (hPSCs) has benefited many fields, from regenerative medicine to disease modeling, with an especially profound effect in cardiac research. Coupled with other novel technologies in genome engineering, hPSCs offer a great opportunity to delineate human cardiac lineages, investigate inherited cardiovascular diseases, and assess the safety and efficacy of cell-based therapies. In this review, we provide an overview of methods for generating genetically engineered hPSC reporters and a succinct synopsis of a variety of hPSC reporters, with a particular focus on their applications in cardiac stem cell biology.

PMID- 29579627 TI - Lenalidomide plus dexamethasone for patients with relapsed or refractory multiple myeloma: Final results of a non-interventional study and comparison with the pivotal phase 3 clinical trials. AB - Lenalidomide (LEN) is an immunomodulatory drug with significant clinical activity against relapsed and refractory multiple myeloma (r/r MM). Based on the pivotal phase 3 trials MM-009 and MM-010, LEN in combination with dexamethasone (DEX) is approved for treatment of patients with MM who have received at least one prior therapy. LEN monotherapy is also approved in first line treatment. Here, we evaluated LEN/DEX combination therapy in a non-interventional study in patients with r/r MM in routine clinical practice. Patients received LEN/DEX as per Summary of Product Characteristics. Ninety-eight patients were treated with at least 1 cycle of LEN/DEX (median age 71 years; range, 42-88), forty-eight patients with at least 6 cycles. The Kaplan-Meier estimate for overall median time to progression was 12.0 months, 13.9 months for patients receiving second line therapy and 10.3 months for third-line or higher-line therapy. The overall response rate was 60.2%. The median overall survival was 24.3 months. The most common adverse events were anemia (32.7%), thrombocytopenia (27.6%) and leukopenia (24.5%). Seven (7.1%) patients developed thromboembolic events despite prophylaxis. In conclusion, the combination of LEN/DEX administered to patients with r/r MM in routine clinical practice showed similar effectiveness and safety as demonstrated in the registration trials. PMID- 29579629 TI - The evolution of "No Evidence of Disease Activity" in multiple sclerosis. AB - The availability of effective therapies for patients with relapsing-remitting multiple sclerosis (RRMS) has prompted a re-evaluation of the most appropriate way to measure treatment response, both in clinical trials and clinical practice. Traditional parameters of treatment efficacy such as annualized relapse rate, magnetic resonance imaging (MRI) activity, and disability progression have an important place, but their relative merit is uncertain, and the role of other factors such as brain atrophy is still under study. More recently, composite measures such as "no evidence of disease activity" (NEDA) have emerged as new potential treatment targets, but NEDA itself has variable definitions, is not well validated, and may be hard to implement as a treatment goal in a clinical setting. We describe the development of NEDA as an outcome measure in MS, discuss definitions including NEDA-3 and NEDA-4, and review the strengths and limitations of NEDA, indicating where further research is needed. PMID- 29579630 TI - Editors' Welcome. PMID- 29579631 TI - Are the high-costs of MS disease-modifying therapies justified? PMID- 29579632 TI - Maternal exercise increases but concurrent maternal fluoxetine prevents the increase in hippocampal neurogenesis of adult offspring. AB - Treating postpartum depression (PPD) with pharmacological antidepressants like fluoxetine (FLX) is complicated because these drugs can remain active in breast milk and potentially affect infant development. Alternatively, non pharmacological treatments such as exercise are associated with beneficial effects on infant development but its potential ability to counter the effects of PPD are largely unknown. To investigate this, we treated dams with corticosterone (CORT) or vehicle (sesame oil) from postpartum days 2-25 to model PPD. Within oil and CORT treatments, dams were also assigned to one of these treatments: 1) exercise (voluntary running wheel) + FLX (10 mg/kg, i.p.), 2) exercise + saline (vehicle for FLX), 3) no exercise + FLX, 4) no exercise + saline. Both male and female offspring were analyzed, and this generated a total of 16 experimental groups for this study. Adult male and female offspring (125 d old) of these dams were tested for anxiety-like behavior in the novelty suppressed feeding test and stress reactivity in the dexamethasone suppression test. Hippocampal tissue was processed for doublecortin, a protein expressed in immature neurons. Regardless of sex, maternal exercise increased neurogenesis in the dorsal hippocampus of adult offspring, but concurrent exposure to maternal fluoxetine prevented this effect. Exposure to either maternal exercise or maternal FLX facilitated HPA negative feedback in adult males but not females. Maternal postpartum CORT also facilitated HPA feedback in adult offspring of both sexes. Collectively, these data indicate that maternal exercise increased dorsal hippocampal neurogenesis in both sexes but differentially affected offspring HPA axis based on sex. Alternatively, maternal postpartum FLX facilitated HPA axis negative feedback only in males. These findings indicate that different types of maternal interventions bear long-term effects on offspring outcome with implications for treating PPD. PMID- 29579633 TI - LC-MS/MS method for the simultaneous analysis of seven antimalarials and two active metabolites in dried blood spots for applications in field trials: Analytical and clinical validation. AB - In epidemiological studies, antimalarials measurements in blood represent the best available marker of drugs exposure at population level, an important driver for the emergence of drug resistance. We have developed a liquid chromatography tandem mass spectrometry method (LC-MS/MS) for the simultaneous quantification of 7 frequently used antimalarials (amodiaquine, chloroquine, quinine, sulfadoxine, pyrimethamine, mefloquine, lumefantrine) and 2 active metabolites (N-desethyl amodiaquine, desbutyl-lumefantrine) in 10-MUl dried blood spots (DBS). This sampling approach is suitable for field studies wherein blood samples processing, transportation and storage are problematic. Sample preparation included extraction from a 3 mm-disk punched out of the DBS with 100-MUl of methanol + 1% formic acid containing deuterated internal standards for all drugs. Good performances were achieved in terms of trueness (-12.1 to +11.1%), precision (1.4 15.0%) and sensitivity, with lower limits of quantification comprised between 2 ng/ml (sulfadoxine) and 20 ng/ml (chloroquine, quinine, pyrimethamine, mefloquine, lumefantrine and desbutyl-lumefantrine). All analytes were stable in DBS kept for 24 h at room temperature and at 37 degrees C. The developed assay was applied within the frame of a pharmacokinetic study including 16 healthy volunteers who received a single dose of artemether-lumefantrine. Lumefantrine concentrations in plasma and in DBS were highly correlated (R = 0.97) at all time points, confirming the assumption that lumefantrine concentrations determined in DBS confidently reflect blood concentrations. The blood/plasma ratio of 0.56 obtained using the Bland-Altman approach (and corresponding to the slope of the linear regression) is in line with very low penetration of lumefantrine into red blood cells. This sensitive multiplex LC-MS/MS assay enabling the simultaneous analysis of antimalarials in DBS is suitable for epidemiological studies in field conditions. PMID- 29579634 TI - Separation and characterization of allergenic polymerized impurities from cephalosporin for injection by trap free two-dimensional high performance size exclusion chromatography * reversed phase liquid chromatography coupled with ion trap time-of-flight mass spectrometry. AB - As requested by regulatory authorities, polymerized impurities are an important issue of quality control. In this study, we presented the utilization of a trap free two-dimensional chromatography, which was consisted by a high performance size exclusion chromatography (HPSEC) and a reversed-phase liquid chromatography (RP-LC) coupled to ion trap time-of-flight mass spectrometry with positive mode of electrospray ionization, to separate and characterize ten allergenic impurities in ceftazidime for injection, cefazolin sodium for injection, cefoperazone sodium and sulbactam sodium for injection and cefamandole nafate for injection. An effective method for characterizing the polymerized impurities in beta-lactam antibiotics was established on the basis of column-switching technique which effectively combined the advantages of HPSEC and the ability of RP-HPLC to identify the special impurities. In the first dimension, the column was the Xtimate SEC-120 analytical column (7.8 mm * 30 cm, 5 MUm) and the flow rate was 1.0 mL min-1 with gradient elution using 0.005 mol L-1 phosphate buffer solution at pH 7.0 and acetonitrile as mobile phase. In the second dimension, the analytical column was ZORBAX SB-C18 (4.6 * 150 mm, 3.5 MUm) using ammonium formate solution (10 mM) and ammonium formate (8 mM) in [acetonitrile-water (4:1, v/v)] solution as mobile phase at a flow rate of 0.4 mL min-1. Eluent associate with each peak separated in the first dimension was trapped by a 20 MUL quantitative loop and then transferred (via a six-port valve) into the second dimension system with volatile mobile phase. Through the multiple heart-cutting 2D-LC approach and online desalting technique, the problem of incompatibility between non-volatile mobile phase and mass spectrometry was solved completely. The fragmentation behaviors of ten allergenic impurities were studied. The structures of ten allergenic impurities in cephalosporin drug substance were deduced based on the HPLC-MSn data, in which four impurities were polymerized impurities. The forming factors of polymerized impurity in cephalosporins were also studied. PMID- 29579635 TI - Silylation of acetaminophen by trifluoroacetamide-based silylation agents. AB - In the presented report, we have described the silylation reaction between the amide group in acetaminophen and a two most popular trifluoroacetamide-based silylation reagents - BSTFA and MSTFA. Both reagents had a amide groups on structures. An investigation was made through the performance of a set of experiments, GC-MS analysis, and a theoretical study, namely interpretation of mass spectra, presentation of the resonance states of all the involved compounds and SN2 reaction schemes, which was found to be different when BSTFA and MSTFA was applied. The negligible effect of used solvent was also described. The fragmentation of TMS-derivatives (MS spectra) was presented and it has confirmed our previous investigations with silylation of pharmaceuticals, and a general rules of fragmentation patterns. Thanks to this the structure of di-O,O-TMS acetaminophen was proven.

AB - The combination of dexmedetomidine (DEX) and propofol (PPF) is extensively used in the field of anaesthesiology. This study aimed to develop and validate a rapid, simple and sensitive ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for the determination of DEX in human plasma. The method was applied to evaluate the effect of DEX concentration on the target-controlled infusion (TCI) concentration of PPF. Analytes were separated on a Waters XTERRA(r) MS C18 column with a mobile phase of acetonitrile-methanol water containing 0.1% formic acid and 5 mM ammonium acetate (70:10:20, v/v/v) at a flow-rate of 0.3 mL/min. Mass spectrometry was performed in the positive selection reaction monitoring mode. The 201.12 -> 95.12 and 515.29 -> 275.68 mass transitions of DEX and IS (telmisartan), respectively, were monitored. The calibration curve of DEX was linear over the concentrations of 0.1-10 ng/mL. The intra-batch and inter-batch precisions of quality control samples were less than 10.05% and had accuracies of less than 6.25%. The newly developed method was successfully applied to quantify the DEX concentrations of plasma samples from 34 patients who were co-medicated with DEX prior to receiving anaesthesia by PPF. Results showed that comedication with DEX could reduce the requirements of PPF. Specifically, it was firstly found that the concentration of DEX is negatively correlated with the TCI concentration of PPF at the time of loss of consciousness.

AB - Numerous reports on the interactions between the immune and endocrine systems, especially growth hormone axis, can be found in the literature. Growth hormone acts mainly indirectly through insulin-like growth factor-1, which stimulates the growth and development processes, metabolism of lipids, proteins, and carbohydrates, and it also has a modulating effect on the cells of the immune system. Several studies have been conducted on the influence of growth hormone therapy on the immunological parameters in children and adults with and without growth hormone deficiency. However, there have been no definite results and some of them have been even contradictory. Some studies have suggested that administration of growth hormone increases the production of tumor necrosis factor and certain pro- and anti-inflammatory cytokines; whereas other studies have demonstrated the lack of correlation between growth hormone and interleukins. The aim of this paper was to evaluate the available literature on the interaction between growth hormone and TNF-alpha, pro-inflammatory (IL-1beta, IL-2, IL-6) and anti-inflammatory (IL-4, IL-10) interleukins.

AB - The last decades have seen the increasing prevalence of thyroid disorders. These augmentations could be the consequence of the increasing contamination of the environment by chemicals that may disrupt the thyroid function. Indeed, in vitro studies have shown that many chemicals contaminating our environment and highlighted in human serum, are able to interfere with the thyroid function. Given the crucial importance of thyroid hormones on neurodevelopment in fetus and newborns, the influence of these pollutants on newborn thyroid homeostasis is a major health concern. Unfortunately, the overall evidence for a deleterious influence of environmental pollutants on thyroid remains poorly studied. Therefore, we assessed the contamination by polychlorinated biphenyls (PCBs), organochlorine pesticides and perfluorinated compounds (PFC) in 221 cord blood samples collected in Belgium between 2013 and 2016. Our results showed that compared to previous studies performed on newborns recruited in Belgium during the two last decades, the present pollutant contamination is declining. Multivariate statistical analyses pointed out a decrease of thyroid stimulating hormone (TSH) level in male newborns with detectable level of 4,4'- dichlorodiphenyldichloroethylene (4,4'-DDE) in comparison with those with no detectable level (p = 0.025). We also highlighted a negative association between perfluorononanoic acid (PFNA) concentration and TSH in male newborns (p = 0.018). Logistic regression showed increased odds ratio for presentation of hypothyroid in mother for each one unit augmentation of log natural concentration of PFOA (OR = 2.30, [1.18-4.5]) and PFOS (OR = 2.03 [1.08-3.83]). Our findings showed that the residual contamination by PFCs and organochlorine pollutants in cord blood are correlated with thyroid hormone in the newborns and the risk of hypothyroid in mothers.

AB - Retinoblastoma (RB) is a pediatric intraocular tumor caused by mutations in retinoblastoma (RB1) gene. We have generated induced pluripotent stem cell line VRFi001-A from a bilateral retinoblastoma patient with heterozygous RB1 gene deletion. The iPSC line VRFi001-A retained the mutation and expressed pluripotency markers, had a normal karyotype and was capable of trilineage differentiation. PMID- 29579640 TI - Soybean TCP transcription factors: Evolution, classification, protein interaction and stress and hormone responsiveness. AB - TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) transcription factors, a family of plant specific proteins, play crucial roles in plant growth and development and stress response. However, systematical information is unknown regarding the TCP gene family in soybean. In the present study, a total of 54 GmTCPs were identified in soybean, which were grouped into 11 groups with the typical TCP conserved domains. Phylogenetic relationship, protein motif and gene structure analyses distinguished the GmTCPs into two homology classes: Class I and Class II. Class II was then differentiated into two subclasses: CIN and CYC/TB1. Unique cis element number and composition existed in the promoter regions which might be involved in the gene transcriptional regulation of different GmTCPs. Tissue expression analysis demonstrated the diverse spatiotemporal expression profiles of GmTCPs. Furthermore, the interaction protein of one previously functionally unknown TCP protein-GmTCP8 was investigated. Yeast two-hybrid assay showed the interaction between GmTCP8 and an abscisic acid receptor (GmPYL10). QRT-PCR assays indicated the distinct expression profiles of GmTCPs in response to abiotic stresses (heat, drought and salt) and stress-related signals (abscisic acid, brassinolide, salicylicacid and methyl jasmonate). These results will facilitate to uncover the possible roles of GmTCPs under abiotic stress and hormone signal responses in soybean. PMID- 29579641 TI - Expression of heterologous lycopene beta-cyclase gene in flax can cause silencing of its endogenous counterpart by changes in gene-body methylation and in ABA homeostasis mechanism. AB - Previously we described flax plants with expression of Arabidopsis lycopene beta cyclase (lcb) gene in which decreased expression of the endogenous lcb and increased resistance to fungal pathogen was observed. We suggested that co suppression was responsible for the change. In this study we investigated the molecular basis of the observed effect in detail. We found that methylation changes in the Lulcb gene body might be responsible for repression of the gene. Treatment with azacitidine (DNA methylation inhibitor) confirmed the results. Moreover, we studied how the manipulation of carotenoid biosynthesis pathway increased ABA level in these plants. We suggest that elevated ABA levels may be responsible for the increased resistance of the flax plants to pathogen infection through activation of chitinase (PR gene).

AB - An efficient, high yields and rapid synthesis of N-tert-butyl-4-(4-substituted phenyl)-2-((substituted-2-oxo-2H-chromen-4-yl)methylthio)-6-oxo-1,6 dihydropyrimidine-5-carboxamide derivatives (4a-4j) under microwave-irradiation has been described. All the newly synthesized compounds (4a-4j) were characterized by elemental analysis and spectroscopic studies. The synthesised compounds (4a-4j) were evaluated for their antibacterial activity by agar-well diffusion method and anti-inflammatory activity by egg albumin denaturation method. The compound (4f) exhibits antibacterial effect with MIC-2.5 MUg/mL against gram positive S. aureus bacterial strain compared to standard ciprofloxacin drug (MIC-10 MUg/mL). The compound (4c) shows an inhibition of heat induced protein denaturation 75.42% at a concentration of 31.25 MUg/ml and is almost ten times more active than compared to standard aceclofenac drug (5.50%). Molecular docking study has been performed for all the synthesized compounds with S. aureus dihydropteroate synthetase (DHPS) and results obtained are quite promising.

PMID- 29579644 TI - Physiotherapeutic interventions in multiple sclerosis across Europe: Regions and other factors that matter. AB - BACKGROUND: A wide variety of interventions exists in physical therapy (PT), but knowledge about their use across different geographical regions is limited. This study investigated the use of PT interventions in people with multiple sclerosis (MS) across Europe. It aimed to determine whether regions differ in applying interventions, and explore whether factors other than regions play a role in their use. METHODS: In an online cross-sectional survey, 212 respondents from 115 European workplaces providing PT services to people with MS representing 26 countries (four European regions) participated. Cluster analysis, Pearson Chi squared test and a Poisson regression model were used to analyze the data. RESULTS: Thirteen of 45 listed PT interventions were used by more than 75% of centers, while nine interventions were used by less than 25%. For 12 interventions, regions differed markedly in their use. Cluster analysis of centers identified four clusters similar in their intervention use. Cluster assignment did not fully align with regions. While center region was important, center size, number and gender of physical therapists working in the center, and time since qualification also played a role. Cluster analysis exploring the use of the interventions provided the basis for a categorization of PT interventions in line with their primary focus: 1. Physical activity (fitness/endurance/resistance) training; 2. Neuroproprioceptive "facilitation/inhibition"; 3. Motor/skill acquisition (individualized therapy led); 4. Technology based interventions. CONCLUSIONS: To our knowledge this is the first study that has explored this topic in MS. The results broaden our understanding of the different PT interventions used in MS, as well as the context of their use.

AB - Contamination of surface and drinking water due to the presence of Escherichia coli bacteria is a major cause of water-borne disease outbreak. To address unmet challenges for practical pathogen detection in contaminated samples, we report fabrication of thermally reduced graphene oxide-based field-effect transistor (rGO FET) passivated with an ultrathin layer of Al2O3 for real-time detection of E. coli bacteria. The sensor could detect a single E. coli cell within 50 s in a 1 uL sample volume. The ultrathin layer of Al2O3 acted as a barrier between rGO and potential interferents present in the sample. E. coli specific antibodies anchored on gold nanoparticles acted as probes for selective capture of E. coli. The high density of negative charge on the surface of E. coli cells strongly modulates the concentration of majority charge carriers in the rGO monolayer, thereby allowing real-time monitoring of E. coli concentration in a given sample. With a low detection limit of single cell, the FET sensor had a linear range of 1 100 CFU in 1 uL volume of sample (i.e., 103 to 105 CFU/ mL). The biosensor with good selectivity and rapid detection was further successfully demonstrated for E. coli sensing in river water. The rGO-based FET sensor provides a low cost and label-free approach, and can be mass produced for detection of a broad spectrum of pathogens in water or other liquid media.

AB - Vascular endothelial growth factor (VEGF) is a key regulator of vascular formation and a predominant protein biomarker in cancer angiogenesis. Owing to its crucial roles in the cancer metastasis, VEGF detection and quantification is of great importance in clinical diagnostics. Today, there exist a wide variety of detection strategies for identifying many types of disease biomarkers, especially for VEGF. As artificial single-stranded DNA or RNA oligonucleotides with catalytic and receptor properties, aptamers have drawn lots of attention to be applied in biosensing platforms due to their target-induced conformational changes as well as high stability and target versatility. So far, various sensitivity-enhancement techniques in combination with a broad range of smart nanomaterials have integrated into the design of novel aptasensors to improve detection limit and sensitivity of analyte detection. This review article provides a brief classification and description of the research progresses of aptamer-based biosensors and nanobiosensors for the detection and quantitative determination of VEGF based on optical and electrochemical platforms.

AB - The current study aims at monitoring the role of the different natural environments on the physical properties and fire hazards of HIPS composites ageing in Turpan and Qionghai. The results indicated that the chromatic aberration and degradation of surface appearance intensified with the increasing ageing time. More flame retardants migrated and were eroded for HIPS composites ageing in Qionghai than those ageing in Turpan, which was caused by the combination of sunlight, high temperature and rainwater in Qionghai. After degradation in the natural environments, the HIPS composites possessed the lower thermal stability and char residues, more toxic gases release, higher peak heat release rate and fire hazard. For example, the peak heat release rate in Qionghai increased by 88.9%, which is much higher than that of in Turpan (55.6%). Moreover, the tensile strength and elongation at break decreased by 46% and 59% for HIPS composites ageing in Turpan and reduced by 53% and 67% for HIPS composites aged in Qionghai, respectively. The results demonstrate that more serious degradation of physical properties and higher fire hazard for HIPS composites ageing in Qionghai than those in Turpan due to the different natural ageing environments. PMID- 29579648 TI - A representative overview of the genetic diversity and lipooligosaccharide sialylation in Campylobacter jejuni along the broiler production chain in France and its comparison with human isolates. AB - Campylobacter jejuni is the most common cause of bacterial gastroenteritis worldwide and is associated with post-infectious neuropathies. Moreover, the chicken reservoir is described as the main source of human infection and C. jejuni sialylated lipooligosaccharides seem to play an important role in the pathogenesis of neuropathies. In this study, MultiLocus Sequence Typing (MLST) and Comparative Genomic Fingerprinting using 40 assay genes (CGF40) were used to describe C. jejuni populations within clinical isolates and a representative collection of isolates from French poultry production. In addition, the sialylation of C. jejuni LOS was assessed. Here, we report high levels of genetic diversity among both chicken and human disease C. jejuni populations. The predominance of the ST-21, ST-45, and ST-464 complexes in chicken isolates and of the ST-21, ST-206, and ST-48 complexes in the clinical isolates was observed as were correlations between some MLST and CGF40 genotypes. Furthermore, some C. jejuni genotypes were frequently isolated among clinical cases as well as all along the broiler production chain, suggesting a potentially high implication of chicken in human campylobacteriosis in France. Finally, the LOS classes A, B and C were predominant within clinical C. jejuni isolates supporting the hypothesis of a benefit in infectivity for C. jejuni isolates showing sialylated LOS.

AB - The age and ability of salt marshes to accumulate and sequester carbon is often assessed using the carbon isotopic signatures (Delta14C and delta13C) of sedimentary organic matter. However, transfers of allochthonous refractory carbon (CRF) from the watershed to marshes would not represent new C sequestration. To better understand how refractory carbon (CRF) inputs affect assessments of marsh age and C sequestration, Delta14C and delta13C of both total organic carbon (TOC), CRF, and non-CRF organic matter fractions were measured in salt marshes from four contrasting systems on the North Atlantic coast. To our knowledge, no salt marsh sediment study has considered refractory or allochthonous carbon in carbon budget calculations or the impact on chronologies. Stable and radiogenic isotope data suggest that while TOC was dominated by autochthonous plant inputs, CRF was dominated by locally recycled or allochthonous C, the delivery of which was controlled by the size and slope of each watershed. Steep-gradient rivers analyzed delivered Delta14C-depleted CRF to their estuarine marshes, while the site located in the low-gradient river was associated with larger CRF content. Finally, the marsh isolated from riverine input contained the least fraction of TOC as CRF. Laterally transported CRF caused only a small offset in Delta14C in relation to TOC in low-gradient systems (average Delta14C offset was -44.4 and 24.20/00 at each location). However, the presence of allochthonous Delta14C depleted CRF in sediments of steep-gradient rivers led to large overestimates of the time of organic matter deposition (i.e. apparent age was older than the 'true' time of deposition) (Delta14C offset ranged from -170.6 to -528.90/00). Further, reliance on TOC or loss on ignition analyses to calculate C sequestration by marshes might produce overestimates of at least as much as 10 to 20% since neither account for the lateral transport of allochthonous carbon. PMID- 29579651 TI - Determination of tylosin excretion from sheep to assess tylosin spread to agricultural fields by manure application. AB - Antibiotics administered to livestock are partly excreted with urine and feces. As livestock excrement is used as manure on agricultural fields, soil may be contaminated by excreted antibiotics, potentially resulting in the development of antibiotic-resistant bacteria. Therefore, it is necessary to determine the amount of antibiotic administered to livestock that could spread to agricultural fields through manure application. This study reveals the excretion ratio of tylosin from sheep. After developing an analysis procedure for tylosin in urine and feces from sheep, a tylosin excretion study was performed with two sheep. Tylosin was excreted in urine and feces for four days, after which its concentrations dropped below the limits of quantification (urine: 0.5MUg/kg, feces: 2.4MUg/kg). The total excretion ratio was 11% on average. The results of our study can provide useful knowledge for treating excrement in order to prevent the spread of antibiotics to agricultural fields through manure application. PMID- 29579652 TI - Analytical approaches for the determination of personal care products and evaluation of their occurrence in marine organisms. AB - Contamination of the aquatic environment caused by multiple human activities may exert a negative impact on all living organisms. Several contaminants of emerging concern such as personal care products (PCPs) are continuously released into the aquatic environment where they are biologically active and persistent. This work reviews the current knowledge, provided by papers published after 2010 and indexed by SciFinder, Scopus, and Google search engines, about the determination and occurrence of PCPs in marine biota. Analytical methodologies have been critically reviewed, emphasizing the importance of green and high-throughput approaches and focusing the discussion on the complexity of the solute-matrix interaction in the extraction step, as well as the matrix effect in the instrumental determination. Finally, the worldwide distribution of PCPs is surveyed, taking into account the concentrations found in the same organism in different marine environments. Differences among various world areas have been highlighted, evidencing some critical aspects from an environmental point of view.

AB - Conversion of levulinic acid (LA) to gamma-valerolactone (GVL) over a ruthenium carbon (Ru/C) catalyst using formic acid (FA) as the sole hydrogen source in cellulose hydrolysis process was investigated. The reaction was accelerated using Ru(5wt%)/C as the catalyst and by adding triethylamine. The highest LA conversion (87.26%) and GVL yield (80.75%) were obtained using 10g/mol (LA) catalyst and 150mL/mol (LA) triethylamine at 160 degrees C for 180min. In this reaction, the hydrogenation process can only be accomplished in the presence of FA, which is the byproduct of LA production from cellulose hydrolysis. The application of this new route not only improves the economy of the process, but also avoids the energy-costly separation of LA from the LA and FA aqueous mixture. A new reaction pathway for the conversion of LA and FA into GVL over Ru/C with triethylamine was proposed. PMID- 29579654 TI - Increased nutrient concentrations in Lake Erie tributaries influenced by greenhouse agriculture. AB - Greenhouse production of vegetables is a growing global trade. While greenhouses are typically captured under regulations aimed at farmland, they may also function as a point source of effluent. In this study, the cumulative impacts greenhouse effluents have on riverine macronutrient and trace metal concentrations were examined. Water samples were collected Bi-weekly for five years from 14 rivers in agriculturally dominated watersheds in southwestern Ontario. Nine of the watersheds contained greenhouses with their boundaries. Greenhouse influenced rivers had significantly higher concentrations of macronutrients (nitrogen, phosphorus, and potassium) and trace metals (copper, molybdenum, and zinc). Concentrations within greenhouse influenced rivers appeared to decrease over the 5-year study while concentrations within non greenhouse influenced river remained constant. The different temporal pattern between river types was attributed to increased precipitation during the study period. Increases in precipitation diluted concentrations in greenhouse influenced rivers; however, non-influenced river runoff proportionally increased nutrient mobility and flow, stabilizing the observed concentrations of non-point sources. Understanding the dynamic nature of environmental releases of point and non-point sources of nutrients and trace metals in mixed agricultural systems using riverine water chemistry is complicated by changes in climatic conditions, highlighting the need for long-term monitoring of nutrients, river flows and weather data in assessing these agricultural sectors.

AB - Allergic diseases, including respiratory conditions of allergic rhinitis (hay fever) and asthma, affect up to 500 million people worldwide. Grass pollen are one major source of aeroallergens globally. Pollen forecast methods are generally site-based and rely on empirical meteorological relationships and/or the use of labour-intensive pollen collection traps that are restricted to sparse sampling locations. The spatial and temporal dynamics of the grass pollen sources themselves, however, have received less attention. Here we utilised a consistent set of MODIS satellite measures of grass cover and seasonal greenness (EVI) over five contrasting urban environments, located in Northern (France) and Southern Hemispheres (Australia), to evaluate their utility for predicting airborne grass pollen concentrations. Strongly seasonal and pronounced pollinating periods, synchronous with satellite measures of grass cover greenness, were found at the higher latitude temperate sites in France (46-50 degrees N. Lat.), with peak pollen activity lagging peak greenness, on average by 2-3weeks. In contrast, the Australian sites (34-38 degrees S. Lat.) displayed pollinating periods that were less synchronous with satellite greenness measures as peak pollen concentrations lagged peak greenness by as much as 4 to 7weeks. The Australian sites exhibited much higher spatial and inter-annual variations compared to the French sites and at the Sydney site, broader and multiple peaks in both pollen concentrations and greenness data coincided with flowering of more diverse grasses including subtropical species. Utilising generalised additive models (GAMs) we found the satellite greenness data of grass cover areas explained 80-90% of airborne grass pollen concentrations across the three French sites (p<0.001) and accounted for 34 to 76% of grass pollen variations over the two sites in Australia (p<0.05). Our results demonstrate the potential of satellite sensing to augment forecast models of grass pollen aerobiology as a tool to reduce the health and socioeconomic burden of pollen-sensitive allergic diseases. PMID- 29579656 TI - Temporal and spatial variations in sand and dust storm events in East Asia from 2007 to 2016: Relationships with surface conditions and climate change. AB - We analyzed the frequency and intensity of sand and dust storms (SDSs) in East Asia from 2007 to 2016 using observational data from ground stations, numerical modeling, and vegetation indices obtained from both satellite and reanalysis data. The relationships of SDSs with surface conditions and the synoptic circulation pattern were also analyzed. The statistical analyses demonstrated that the number and intensity of SDS events recorded in spring during 2007 to 2016 showed a decreasing trend. The total number of spring SDSs decreased from at least ten events per year before 2011 to less than ten events per year after 2011. The overall average annual variation of the surface dust concentration in the main dust source regions decreased 33.24MUg/m3 (-1.75%) annually. The variation in the temperatures near and below the ground surface and the amount of precipitation and soil moisture all favored an improvement in vegetation coverage, which reduced the intensity and frequency of SDSs. The strong winds accompanying the influx of cold air from high latitudes showed a decreasing trend, leading to a decrease in the number of SDSs and playing a key role in the decadal decrease of SDSs. The decrease in the intensity of the polar vortex during study period was closely related to the decrease in the intensity and frequency of SDSs. PMID- 29579657 TI - The effect of selected acidic or alkaline chemical agents amendment on leachability of selected heavy metals from sewage sludge. AB - The aim of the study was to evaluate the effect of acidic (Fenton's reagent, peracetic acid) or alkaline (CaO) chemical agents amendment on chemical forms of Pb, Ni, and Cd in sewage sludge. The dose of Fenton's reagent was as follows: Fe2+=1g.L-1, Fe2+/H2O2=1:100; stabilisation lasted for 2h. The dose of CaO was equal to 1g CaO.gd.m.-1. The dose of CH3COOOH was 2.5g.L-1. Total concentration of all metals in the digested sewage sludge was higher than in the soil and it did not meet Polish law requirements. Acidic chemical stabilisation of sludge did not significantly decrease total metal content in the sludge. Amendment of CaO decreased the content of Pb, Cd, and Ni in the sludge. Chemical fractions of heavy metals were identified in the sludge (exchangeable, carbonate bound, iron oxides bound, organic and residual). The results indicate that stabilisation of the sludge with Fenton's reagent and peracetic acid increased the exchangeable fraction of Pb, Cd, and Ni compared to the digested sludge, but it did not increase shares of mobile forms of metals considered as a total of I-st and II-nd fraction. Amendment of CaO increased percent share of examined metals in residual fraction. Not-mobile fractions of examined metals overweight the mobile ones in all sludge samples regardless of the treatment method.

AB - Assessment of Land Surface Models (LSMs) at heterogeneous terrain and climate regimes is essential for understanding complex hydrological and biophysical parameterization. This study utilized the two LSMs, Community Land Model (CLM 4.0) and three layer Variable Infiltration Capacity (VIC-3L), to estimate the interaction between land surface and atmosphere by means of energy fluxes including net radiation (RN), sensible heat flux (H), latent heat flux (LE), and ground heat flux (G). The modeled energy fluxes were analyzed at two sites: Freeman Ranch-2 (FR2) located in the lowland region of Texas (272m), and Providence 301 (P301) located on the mountains of Sierra Nevada in California (2015m) from 2003 to 2013. RN was underestimated by CLM with bias -25.06Wm-2 due to its snow hydrology scheme at P301. LE was overestimated by the VIC during summer precipitation and had a positive bias of 5.51Wm-2, whereas CLM showed a negative bias of -6.58Wm-2 at the FR2 site. G was considered as a residual term in CLM, which caused weak performance at P301, while VIC calculated G as a function of soil temperature, depth, and hydraulic conductivity. In addition, The MOD16 showed similar results with models at FR2; however, at P301, they yielded a correlation value of 0.85 and 0.21 for LSMs and MOD16, respectively. The later has lower correlation with in situ specifically in summer season caused by erroneous biophysical or meteorological inputs to the algorithms. The sensitivity analysis between soil moisture and turbulent fluxes, exhibited negative trend (especially for LE at P301) due to topography and snow cover. The results from this study are conducive to improvements in models and satellite based characterization of water and energy fluxes, especially at rugged terrain with high elevation, where observational experiments are difficult to conduct. PMID- 29579659 TI - Temporal-spatial variability in correlations of drought and flood during recent 500years in Inner Mongolia, China. AB - Drought and flood are two frequent natural disasters in the world. Identification of temporal-spatial variability and its scale-dependence for drought-flood correlation can help to predict, hence to alleviate the losses. The correlations of drought with flood at 1, 3, 5, 10, 50 and 100-year scales at moving window of 30years during recent 500years were analyzed by spatial statistics based on geographical information system in Inner Mongolia, China. The results demonstrated that the frequency and intensity of two disasters increased generally during last 500years. The drought-flood correlations indicated a rhythm of alternate positive and negative relation with unspecific timescale, enlarged by prolonging of time scale from 1year to 5years, for either frequency or intensity. A lag effect, flood always occurred at the 4 or 5year following drought was observed. Located in the climatic marginal zone, eastern study region was strongly affected by the East Asia monsoon, showed a weak drought-flood correlation; western study region was controlled by continental climate, showed a significant drought-flood correlation. These correlations were also affected by periodic ENSO disturbance and mountain terrains. With the climatic changes, the drought-flood correlations also change in recent decades. These long-range correlations at various temporal-spatial scales provide a theoretical basis for the scientific prediction of drought and flood outbreaks, for a long term as well as a short wavelet. PMID- 29579660 TI - Assessing the associations of daily respiratory symptoms and lung function in schoolchildren using an Air Quality Index for ozone: Results from the RESPOZE panel study in Athens, Greece. AB - BACKGROUND: Air Quality indicators or indices (AQIs) are mainly used for communicating the air pollution levels and risk to the general population. However, very few epidemiological studies have used AQIs for characterizing exposure. OBJECTIVE: In the framework of the RESPOZE panel study we evaluated the association of daily ozone AQI levels with the daily occurrence of respiratory symptoms and Peak Expiratory Flow (PEF) and compared the effects with those estimated using measurements from fixed outdoor monitoring sites, in the city of Athens, Greece. MATERIALS AND METHODS: A panel of 97 children, aged 10-11years, was followed intensively for 35days (5weeks) during the academic year 2013-14. PEF and symptoms were recorded daily by each child. Two ozone AQIs classifying the air quality into 7 categories of increasing severity, were calculated; one characterizing the whole Athens area and one the local area around the child's residence and school. Measurements from fixed sites were also used. Mixed effects models for repeated measurements were applied, adjusting for several confounders. RESULTS: Increasing ozone levels were associated with increased incidence of symptoms, but the strongest and most statistically significant associations were found with the local air quality characterization with the AQI. Specifically, an increase in AQI-local by one category was associated with 34% (95% CI: 9%, 64%) increased odds of stuffy nose. When the AQI categories were "Bad" and "Severe", an increase in the incidence of cough was observed (OR 3.05 (95% CI: 1.29, 7.22) and 6.42 (95% CI: 1.47, 28.03) respectively). We did not observe a statistically significant association between AQI and PEF. CONCLUSION: Our results show that the use of an AQI based on local conditions may be advantageous over the use of only measurements when investigating the effects of air pollution on health outcomes for improving communication of risk to the public. PMID- 29579661 TI - Microplastic ingestion by Daphnia magna and its enhancement on algal growth. AB - The rapid increase in plastic use over the last few decades has resulted in plastic pollution in freshwater and marine ecosystems. However, more attention has been paid to plastic pollution in marine ecosystems than to freshwater ecosystems. This research determined microplastic ingestion by Daphnia magna and the potential effect of microplastics on the organism's survival and reproduction. The study also examined the potential of microplastics to enhance algal growth in support of understanding effects of microplastic ingestion on the organism. When exposed to 25, 50, and 100mg/L fluorescent green polyethylene microbeads at size of 63-75MUm, D. magna ingested significant amount of plastic microbeads. The number of ingested beads increased with increasing particle concentration and exposure time. However, no significant effect on survival and reproduction was observed although the gut of D. magna was filled with plastic microbeads. In the algal experiment, Raphidocelis subcapitata grew more in the exposure media with the present of plastic microbeads than without plastic microbeads. This result suggests that plastic microbeads could serve as substrates for R. subcapitata to grow. Raphidocelis subcapitata then could be transferred to the organism's gut and provided energy for survival and reproduction. Results of the present study add to the literature of microplastic ingestion by aquatic organisms. Caution should be taken when interpreting hazards of microplastics based on ingestion, such as the measurement unit and the presence of algae in the environment.

AB - Cork boiling wastewater is a very complex mixture of naturally occurring compounds leached and partially oxidized during the boiling cycles. The effluent generated is recalcitrant and could cause a significant environmental impact. Moreover, if this untreated industrial wastewater enters a municipal wastewater treatment plant it could hamper or reduce the efficiency of most activated sludge degradation processes. Despite the efforts to treat the cork boiling wastewater for reusing purposes, is still not well-known how safe these compounds (original compounds and oxidation by-products) will be. The purpose of this work was to apply an HPLC-high resolution mass spectrometry method and subsequent non-target screening using a multivariate analysis method (PCA), to explore relationships between samples (treatments) and spectral features (masses or compounds) that could indicate changes in formation, degradation or polarity, during coagulation/flocculation (C/F) and photo-Fenton (PhF). Although, most of the signal intensities were reduced after the treatment line, 16 and 4 new peaks were detected to be formed after C/F and PhF processes respectively. The use of this non-target approach showed to be an effective strategy to explore, classify and detect transformation products during the treatment of an unknown complex mixture. PMID- 29579663 TI - Composition and functional diversity of microbial community across a mangrove inhabited mudflat as revealed by 16S rDNA gene sequences. AB - The gradient distribution of microbial communities has been detected in profiles along many natural environments. In a mangrove seedlings inhabited mudflat, the microbes drive a variety of biogeochemical processes and are associated with a dramatically changed environment across the tidal zones of mudflat. A better understanding of microbial composition, diversity and associated functional profiles in relation to physicochemical influences could provide more insights into the ecological functions of microbes in a coastal mangrove ecosystem. In this study, the variation of microbial community along successive tidal flats inhabited by mangrove seedlings were characterized based on the 16S rDNA gene sequences, and then the factors that shape the bacterial and archaeal communities were determined. Results showed that the tidal cycles strongly influence the distribution of bacterial and archaeal communities. Dissimilarity and gradient distribution of microbial communities were found among high tidal flat, mid-low tidal flat and seawater. Discrepancies were also as well observed from the surface to subsurface layers specifically in the high tidal flat. For example, Alphaproteobacteria displayed an increasing trend from low tidal to high tidal flat and vice versa for Deltaproteobacteria; Cyanobacteria and Thaumarchaeota were more dominant in the surface layer than the subsurface. In addition, by classifying the microorganisms into metabolic functional groups, we were able to identify the biogeochemical pathway that was dominant in each zone. The (oxygenic) photoautotrophy and nitrate reduction were enhanced in the mangrove inhabited mid tidal flat. It revealed the ability of xenobiotic metabolism microbes to degrade, transform, or accumulate environmental hydrocarbon pollutants in seawater, increasing sulfur-related respiration from high tidal to low tidal flat. An opposite distribution was found for major nitrogen cycling processes. The shift of both composition and function of microbial communities were significantly related to light, oxygen availability and total dissolved nitrogen instead of sediment types or salinity. PMID- 29579664 TI - Environmental correlates underlying elevational richness, abundance, and biomass patterns of multi-feeding guilds in litter invertebrates across the treeline. AB - Elevational richness patterns and underlying environmental correlates have contributed greatly to a range of general theories of biodiversity. However, the mechanisms underlying elevational abundance and biomass patterns across several trophic levels in belowground food webs remain largely unknown. In this study, we aimed to disentangle the relationships between the elevational patterns of different trophic levels of litter invertebrates and their underlying environmental correlates for two contrasting ecosystems separated by the treeline. We sampled 119 plots from 1020 to 1770 asl in forest and 21 plots from 1790 to 2280 asl in meadow on Dongling Mountain, northwest of Beijing, China. Four functional guilds were divided based on feeding regime: omnivores, herbivores, predators, and detritivores. We used eigenvector-based spatial filters to account for spatial autocorrelation and multi-model selection to determine the best environmental correlates for the community attributes of the different feeding guilds. The results showed that the richness, abundance and biomass of omnivores declined with increasing elevation in the meadow, whereas there was a hump-shaped richness pattern for detritivores. The richness and abundance of different feeding guilds were positively correlated in the forest, while not in the meadow. In the forest, the variances of richness in omnivores, predators, and detritivores were mostly correlated with litter thickness, with omnivores being best explained by mean annual temperature in the meadow. In conclusion, hump-shaped elevational richness, abundance and biomass patterns driven by the forest gradient below the treeline existed in all feeding guilds of litter invertebrates. Climate replaced productivity as the primary factor that drove the richness patterns of omnivores above the treeline, whereas heterogeneity replaced climate for herbivores. Our results highlight that the correlated elevational richness, abundance, and biomass patterns of feeding guilds are ecosystem-dependent and that the underlying environmental correlates shifted at the treeline for most feeding guilds. PMID- 29579665 TI - Microplastics in surface waters of Dongting Lake and Hong Lake, China. AB - Microplastics pollution is an environmental issue of increasing concern. Much work has been done on the microplastics pollution in the marine environments. Although freshwaters are potential sources and transport pathways of plastic debris to the oceans, there is a lack of knowledge regarding the presence of microplastics in freshwater systems, especially in China, the world's largest producer of plastics. This study investigated the occurrence and properties of microplastics in surface waters of two important lakes in the middle reaches of the Yangtze River. The concentration ranges of microplastics in Dongting Lake and Hong Lake were 900-2800 and 1250-4650n/m3, respectively. Fiber was the dominant shape. Colored items occupied the majority. Particles with a size of <330MUm comprised >20% of total microplastics collected in both lakes. Most of the selected particles were identified as plastics, with polyethylene (PE) and polypropylene (PP) being the major components. This study can provide valuable reference for better understanding the microplastics pollution in inland freshwater ecosystems. PMID- 29579666 TI - Graphitic carbon nitride based nanocomposites for the photocatalysis of organic contaminants under visible irradiation: Progress, limitations and future directions. AB - Graphitic carbon nitride (g-C3N4) has drawn great attention recently because of its visible light response, suitable energy band gap, good redox ability, and metal-free nature. g-C3N4 can absorb visible light directly, therefore has better photocatalytic ability under solar irradiation and is more energy-efficient than TiO2. However, pure g-C3N4 still has the drawbacks of insufficient light absorption, small surface area and fast recombination of photogenerated electron and hole pairs. This review summarizes the recent progress in the development of g-C3N4 nanocomposites to photodegrade organic contaminants in water. Element doping especially by potassium has been reported to be an efficient method to promote the degradation efficacy. In addition, compound doping improves photodegradation performance of g-C3N4, especially Ag3PO4-g-C3N4 which can completely degrade 10mgL-1 of methyl orange under visible light irradiation in 5min, with the rate constant (k) as high as 0.236min-1. Moreover, co-doping enhances the photodegradation rate of multiple contaminants while immobilization significantly improves catalyst stability. Most of g-C3N4 composites possess high reusability enabling their practical applications in wastewater treatment. Furthermore, environmental conditions such as solution pH, reaction temperature, dissolved oxygen, and dissolved organic matter all have important effects on the photocatalytic ability of g-C3N4 photocatalyst. Future work should focus on the synthesis of innovative g-C3N4 nanocomposites for the efficient removal of organic contaminants in water and wastewater. PMID- 29579667 TI - The impact of highway base-saturation flow rate adjustment on Kuwait's transport and environmental parameters estimation. AB - Traditional transportation systems' management and operation mainly focused on improving traffic mobility and safety without imposing any environmental concerns. Transportation and environmental issues are interrelated and affected by the same parameters especially at signalized intersections. Additionally, traffic congestion at signalized intersections has a major contribution in the environmental problem as related to vehicle emission, fuel consumption, and delay. Therefore, signalized intersections' design and operation is an important parameter to minimize the impact on the environment. The design and operation of signalized intersections are highly dependent on the base saturation flow rate (BSFR). Highway Capacity Manual (HCM) uses a base-saturation flow rate of 1900 passenger car/h/lane for areas with a population intensity greater than or equal to 250,000 and a value of 1750-passenger car/h/lane for less populated areas. The base-saturation flow rate value in HCM is derived from a field data collected in developed countries. The adopted value in Kuwait is 1800passengercar/h/lane, which is the value that used in this analysis as a basis for comparison. Due to the difference in behavior between drivers in developed countries and their fellows in Kuwait, an adjustment was made to the base-saturation flow rate to represent Kuwait's traffic and environmental conditions. The reduction in fuel consumption and vehicles' emission after modifying the base-saturation flow rate (BSFR increased by 12.45%) was about 34% on average. Direct field measurements of the saturation flow rate were used while using the air quality mobile lab to calculate emissions' rates. PMID- 29579668 TI - Spatially distributed potential evapotranspiration modeling and climate projections. AB - Evapotranspiration integrates energy and mass transfer between the Earth's surface and atmosphere and is the most active mechanism linking the atmosphere, hydrosphsophere, lithosphere and biosphere. This study focuses on the fine resolution modeling and projection of spatially distributed potential evapotranspiration on the large catchment scale as response to climate change. Six potential evapotranspiration designed algorithms, systematically selected based on a structured criteria and data availability, have been applied and then validated to long-term mean monthly data for the Shannon River catchment with a 50m2 cell size. The best validated algorithm was therefore applied to evaluate the possible effect of future climate change on potential evapotranspiration rates. Spatially distributed potential evapotranspiration projections have been modeled based on climate change projections from multi-GCM ensembles for three future time intervals (2020, 2050 and 2080) using a range of different Representative Concentration Pathways producing four scenarios for each time interval. Finally, seasonal results have been compared to baseline results to evaluate the impact of climate change on the potential evapotranspiration and therefor on the catchment dynamical water balance. The results present evidence that the modeled climate change scenarios would have a significant impact on the future potential evapotranspiration rates. All the simulated scenarios predicted an increase in potential evapotranspiration for each modeled future time interval, which would significantly affect the dynamical catchment water balance. This study addresses the gap in the literature of using GIS-based algorithms to model fine-scale spatially distributed potential evapotranspiration on the large catchment systems based on climatological observations and simulations in different climatological zones. Providing fine-scale potential evapotranspiration data is very crucial to assess the dynamical catchment water balance to setup management scenarios for the water abstractions. This study illustrates a transferable systematic method to design GIS-based algorithms to simulate spatially distributed potential evapotranspiration on the large catchment systems. PMID- 29579669 TI - Contamination and health risk assessment of PAHs in farmland soils of the Yinma River Basin, China. AB - The concentration, composition, sources and incremental lifetime cancer risk of farmland soil polycyclic aromatic hydrocarbons (PAHs) of the Yinma River Basin were analyzed. In 2016, the total concentration of 16 PAHs ranged from 491.65 to 1007.73 ng/g in May, from 427.31 to 781.38 ng/g in August and from 580.40 to 999.40 ng/g in November, respectively. Levels of seven potentially carcinogenic PAHs generally accounted for 33-36.7% of total 16 PAHs in three seasons, and the PAHs contained two to six rings, mainly Fla, Pyr, and Chr. The correlation analysis suggested that the soil organic matter (SOM) was no correlation with PAHs except for August, and there were no significant relationship between the pH and total PAHs. Isomer ratios indicated that the soil PAHs in the farmland of the Yinma River Basin was determined to be the combustion of coal, biomass, and petroleum. The toxic equivalent (BaPeq) concentrations ranged from 15.2 to 133 ng BaPeq g-1 in three seasons. The 95th percentiles of incremental lifetime cancer risk (ILCR) due to human exposure to farmland soil PAHs of the Yinma River Basin was (1.36 * 10-6) in May, (1.00 * 10-6) in August, and (1.18 * 10-6) in November for children, (1.10 * 10-6) in May, (8.15 * 10-7) in August, and (9.58 * 10-7) in November for adolescence and (1.61 * 10-6) in May, (4.22 * 10-6) in August and (1.40 * 10-6) in November for adulthood. The result indicated a moderate carcinogenic risk and the risk of exposure to farmland soil PAHs was pervasive for residents. This investigation might provide useful information on human exposure to PAHs in soil of the Yinma River Basin, and is valuable for policy makers and scientists. PMID- 29579670 TI - Fluoride contamination in groundwater sources in Southwestern Nigeria: Assessment using multivariate statistical approach and human health risk. AB - The present study investigated the ionic and fluoride concentrations in tap water and its associated health risk to local dwellers of Ogun State (Abeokuta south), Nigeria. 63 samples were collected from twenty-one different locations. Results obtained revealed the mean concentration of fluoride (F-) as 1.23 mg/L. Other water quality parameters such as total dissolved solids (TDS), electrical conductivity (EC), F-, Fe2+, and SO42- surpassed the WHO guidance for drinking water. Strong positive correlation was observed between F- and TDS; F- and pH; TDS and EC; TDS and Mg2+; TDS and SO42-; TDS and HCO3-; EC and HCO3-; EC and SO42 ; Na+ and Cl-; SO42- and Cl-. In addition, Empirical Bayesian Kriging (EBK) model was employed to spatially distribute the concentration of the analyzed elements within the study region. The chronic daily dose (CDD) and hazard quotient (HQ) were also used to evaluate the health risk associated with F-, considering dermal and ingestion as pathways. The results revealed that the associated HQ for infants between the age range of 6-12months within about 91% of the study region surpassed the accepted HQ limit. However, the HQ for age categories 11-16years; >65years; 18-21years; 21years; 16-18years within 95.2%, 90.5%, 80.95% and 100% of the study location were less than 1. Conclusively, the HQ values obtained in this study should serve as a baseline information for water management authorities, policymakers and the society at large towards addressing these pollution issues. PMID- 29579671 TI - External validation of the TIMI risk score for secondary cardiovascular events among patients with recent myocardial infarction. AB - BACKGROUND AND AIMS: Risk stratification of patients with recent myocardial infarction (MI) for subsequent cardiovascular (CV) events helps identify patients most likely to benefit from secondary prevention therapies. This study externally validated a new risk score (TRS2P) for secondary events derived from the TRA2 degrees P-TIMI 50 trial among post-MI patients from two large health care systems. METHODS: This retrospective cohort study included 9618 patients treated for acute MI at either the Cleveland Clinic (CC) or Geisinger Health System (GHS) between 2008 and 2013. Patients with a clinic visit within 2-52 weeks of MI were included and followed for CV death, repeat MI, and ischemic stroke through electronic medical records (EMR). The TRS2P is based on nine factors determined through EMR documentation. Discrimination and calibration of the TRS2P were quantified in both patient populations. RESULTS: MI patients at CC and GHS were older, had more comorbidities, received fewer medications, and had higher 3-year event rates compared to subjects in the TRA2 degrees P trial: 31% (CC), 33% (GHS), and 10% (TRA2 degrees P-TIMI 50). The proposed risk score had similar discrimination across the three cohorts with c-statistics of 0.66 (CC), 0.66 (GHS), and 0.67 (TRA2 degrees P-TIMI 50). A strong graded relationship between the risk score and event rates was observed in all cohorts, though 3-year event rates were consistently higher within TRS2 degrees P strata in the CC and GHS cohorts relative to TRA2P-TIMI 50. CONCLUSIONS: The TRS2P demonstrated consistent risk discrimination across trial and non-trial patients with recent MI, but event rates were consistently higher in the non-trial cohorts. PMID- 29579672 TI - Induction of extracranial arteriogenesis by an arteriovenous fistula in a pig model. AB - BACKGROUND AND AIMS: Arteriogenesis, the positive outward remodeling and growth of pre-existent collateral vessels, holds potential as a novel treatment for ischemic vascular disease. An extracranial arteriogenesis model in a pig will allow us to study molecular changes in a complex arteriolar network in a more clinically relevant large-animal model. To increase fluid shear stress in the brain, an experimental carotid arteriovenous fistula (AVF model) in minipigs was established, providing high flow through the extracranial rete mirabile. The aim of the study was to examine whether creation of a carotid AVF can induce extracranial arteriogenesis in the pig. METHODS: Angiography was performed to demonstrate blood flow diversion. Animals were sacrificed after 0, 3 and 14 days post-surgery and both retia mirabilia were removed. Immunohistochemical analysis was performed to analyze cell proliferation and accumulation of mononuclear cells in the vessel wall. RESULTS: After 3 days of high-flow conditions, increases in vascular cell proliferation (approximately 1.5-fold; p = 0.143) and monocyte invasion (approximately 6-fold; p = 0.057) were observed when compared to animals sacrificed immediately after AVF formation. Quantitative PCR (RT-qPCR) analysis from rete mirabile tissue samples 3 days post-surgery revealed that monocyte chemoattractant protein (MCP)-1 and tissue inhibitor of metalloproteinases (TIMP) 1 were highly upregulated. Expression of the pro-arteriogenic marker, CD44, reached maximum expression level 14 days post-surgery. CONCLUSIONS: In response to high levels of shear stress produced in the pig AVF model, the onset of the arteriogenic process can be induced. This was demonstrated by enhanced cell proliferation, monocyte invasion and vascular remodeling. PMID- 29579673 TI - Associations between normal range albuminuria, renal function and cardiovascular function in a population-based imaging study. AB - BACKGROUND AND AIMS: In patients with impaired renal function and macroalbuminuria, cardiovascular risk factors are highly prevalent, however, whether this is also present in the general population is unclear. We investigated whether normal-range albuminuria and renal function are associated with cardiovascular function in the general population. METHODS: In this cross sectional analysis of the NEO study, urinary albumin-creatinine ratio (UACR), estimated glomerular filtration rate (eGFR), and intima-media thickness were assessed in all participants (n = 6503), and a random subset underwent MRI for pulse wave velocity (n = 2451) and/or cardiac imaging (n = 1138). RESULTS: Multiple linear regression analysis was performed while adjusting for sex, age, smoking, mean arterial blood pressure, total body fat, and fasting glucose. After adjustment, albuminuria and renal function were positively associated with left ventricle (LV) mass index (UACR, 0.941 g/m2 [95% CI: 0.21,1.67] p = 0.012; eGFR, 0.748 g/m2 [95% CI: 0.15,1.35] p = 0.015) and LV cardiac index (UACR, 0.056 L/min/m2 [95% CI: 0.00,0.11] p = 0.038; eGFR, 0.080 L/min/m2 [95% CI: 0.03,0.13] p = 0.001). Albuminuria showed a weak association with arterial thickness (UACR, 0.003 mm [95% CI: 0.00,0.01] p = 0.015) and arterial stiffness (UACR, 0.073 m/s [95% CI: 0.01,0.13] p = 0.036), but not with renal function. No associations were observed for LV ejection fraction and LV diastolic function. CONCLUSIONS: Normal range albuminuria was positively associated with LV mass index, LV cardiac index, arterial thickness and arterial stiffness. Our findings support the hypothesis that even within normal range, albuminuria is a marker of cardiovascular health. PMID- 29579674 TI - Bioremediation of a pentacyclic PAH, Dibenz(a,h)Anthracene- A long road to trip with bacteria, fungi, autotrophic eukaryotes and surprises. AB - Dibenz(a,h)Anthracene (DBahA), classified as a probable human carcinogen (B2) is the first Poly Aromatic Hydrocarbons (PAH) to be chemically purified and used for cancer-based studies. Till date, only 30 papers focus on the bioremediation aspects of DBahA out of more than 200 research publications for each of the other 15 priority PAHs. Thus, the review raises an alarm and calls for efficient bioremediation strategies for considerable elimination of this compound from the environment. This article reviews and segregates the available papers on DBahA bioremoval from the beginning till date into bacteria, fungi and plant-mediated remediation and offers suggestions for the most competent and cost-effective modes to bioremove DBahA from the environment. One of the proficient ways to get rid of this PAH could with the use of biosurfactant-enriched bacterial consortium in DBahA polluted environment, which is given considerable importance here. Among the bacterial and fungal microbiomes, unquestionably the former are the beneficiaries which utilize the breakdown products of this PAH metabolized by the latter. Nevertheless, the use of plant communities for efficient DBahA utilization through fibrous root system is also discussed at length. The current status of DBahA as reflected by the publications at https://www.ncbi.nlm.nih.gov and recommendations among the explored groups [bacterial/fungal/plant communities] for better DBahA elimination are pointed out. Finally, the review emphasizes the pros and cons of all the methodologies used for selective/combinatorial removal of DBahA and present the domain to the researchers to carry forward by incorporating their individual ideas. PMID- 29579675 TI - Removal of lindane wastes by advanced electrochemical oxidation. AB - The effective removal of recalcitrant organochlorine pesticides including hexachlorocyclohexane (HCH) present in a real groundwater coming from a landfill of an old lindane (gamma-HCH) factory was performed by electrochemical oxidation using a BDD anode and a carbon felt cathode. Groundwater (SigmaHCHs = 0.42 mg L 1, TOC0 = 9 mg L-1, pH0 = 7, conductivity = 3.7 mS cm-1) was treated as received, achieving the complete depletion of the HCH isomers and a mineralization degree of 90% at 4 h electrolysis at constant current of 400 mA. Initial groundwater contains high chloride concentration (Cl0- = 630 mg L-1) that is progressively decreased due to its oxidation to different oxychlorine species: Cl2, HClO, ClO-, ClO2- ClO3- and ClO4- some of them (Cl2, HClO, ClO-) playing an important role in the oxidation of organic pollutants. The oxidation rate of chloride (and its oxidized intermediates) depends on the applied current value. Although some of the species generated from them are active oxidants, the presence of inorganic salts is detrimental to the efficiency of the electrochemical process when working at current densities above 100 mA due to the high consumption of hydroxyl radicals in wasting reactions. The initial organic carbon content is not crucial for the extension of the process but high organic loads are more profitable for cost effectiveness. The addition of a supporting electrolyte to the solution could be interesting since it increases the conductivity, reducing the cell potential and therefore, decreasing the energy consumption. PMID- 29579676 TI - Ciprofloxacin vs. temperature: Antibiotic toxicity in the free-floating liverwort Ricciocarpus natans from a climate change perspective. AB - The physiological responses of the aquatic liverwort Ricciocarpus natans to ciprofloxacin (Cipro) exposure under different growth temperatures were investigated. Cipro appears to act as an inhibitor of mitochondrial Complex III by blocking the oxidation of quinol, resulting in the formation of hydrogen peroxide (H2O2). H2O2 accumulation upon Cipro exposure is responsible for decreased photosynthesis in plants. The amount of H2O2 in plants is kept under control by antioxidant enzymes, whose activities are central to the responses of plants to Cipro yet are influenced by temperature. Increased temperature favored Cipro uptake by plants as well as its deleterious effects on mitochondrial activity; however, it also favored the activity of antioxidant enzymes, thereby preventing the exacerbation of the deleterious effects of Cipro. The uptake of Cipro by plants appears to be largely a passive process, although some uptake must be driven by an energy-consuming process. Ricciocarpus natans should be considered for programs aimed at the reclamation of Cipro since this plant exhibits high Cipro-tolerance, the capacity for accumulation and increased uptake rates of the antibiotic with increasing temperatures (from 20 to 30 degrees C). PMID- 29579677 TI - Humic substances, their microbial interactions and effects on biological transformations of organic pollutants in water and soil: A review. AB - Depicted as large polymers by the traditional model, humic substances (HS) tend to be considered resistant to biodegradation. However, HS should be regarded as supramolecular associations of rather small molecules. There is evidence that they can be degraded not only by aerobic but also by anaerobic bacteria. HS presence alters biological transformations of organic pollutants in water and soil. HS, including humin, have a great potential for an application in aerobic and anaerobic wastewater treatment as well as in bioremediation. Black carbon materials, including char (biochar) and activated carbon (AC), long recognized effective sorbents, have been recently discovered to act as effective redox mediators (RM), which may significantly accelerate degradation of organic pollutants in a way similar to HS. Humic-like coating on the biochar surface has been identified. Explanation of mechanisms and possibility of applications of black carbon materials have only started to be explored. Results of many original and review papers, presented and discussed in this article, show an enormous potential for an interesting, multidisciplinary research as well as for a development of new, green technologies for biological wastewater treatment and bioremediation. Future research areas have been suggested. PMID- 29579678 TI - Organohalogen contaminants in common loons (Gavia immer) breeding in Western Alberta, Canada. AB - We examined the influence of biological and geographical factors on the levels and patterns of organohalogen contaminants in blood of adult common loons (Gavia immer) collected from 20 lakes in Alberta, Canada. The loons were captured in the 2006 and 2007 breeding seasons over a 900 m elevation gradient across the eastern slope of the Canadian Rocky Mountains. While PCBs dominated the composition of these contaminants in loons at all sites (?PCBs > p,p'-DDE > ?PBDEs > ?Chlordanes > HCB), p,p'-DDE and ?PBDEs were also important, averaging approximately 50% and 20% of total PCB concentrations, respectively. ?PCBs and ?PBDEs were higher in males than in females. Inter-lake variation was apparent for contaminant concentrations and patterns and were largely explained by dietary signatures (delta15N and delta13C) and proximity to a large hydroelectric dam. Mean ?PCB (19.6 ng/g wet weight (ww)) and organochlorine pesticide (OCP) (p,p'-DDE: 11.8 ng/g, cis-nonachlor: 0.10 ng/g, trans-nonachlor: 0.32 ng/g, HCB: 0.34 ng/g ww) concentrations in loons were approximately 4- to 17-fold lower than average concentrations reported in common loons from Atlantic Canada and were well below concentrations which have been associated with impaired reproductive success and eggshell thinning in other piscivorous birds. Dominant PBDE congeners were BDE47, BDE99, and BDE100. The regional mean for ?PBDEs (4.04 ng/g ww) in loons from the present study was within the range reported for ?PBDEs in nestling bald eagle plasma from British Columbia. This is the first report of PBDEs in loons and the first report of PCBs and OCPs in common loons from Western North America. PMID- 29579679 TI - Hg in snow cover and snowmelt waters in high-sulfide tailing regions (Ursk tailing dump site, Kemerovo region, Russia). AB - Gold-bearing polymetallic Cu-Zn deposits of sulphur-pyrite ores were discovered in the Novo-Ursk region in the 1930s. The average content of mercury (Hg) was approximately 120 MUg/g at the time. A comprehensive study of Hg distribution in waste of metal ore enrichment industry was carried out in the cold season on the tailing dump site and in adjacent areas. Mercury concentration in among snow particulate, dissolved and colloid fractions was determined. The maximal Hg content in particulate fraction from the waste tailing site ranged 230-573 MUg/g. Such indices as the frequency of aerosol dust deposition events per units of time and area, enrichment factor and the total load allowed to establish that the territory of the tailing waste dump site had a snow cover highly contaminated with dust deposited at a rate of 247-480 mg/(m2?day). Adjacent areas could be considered as area with low Hg contamination rate with average deposition rate of 30 mg/(m2?day). The elemental composition of the aerosol dust depositions was determined as well, which allowed to reveal the extent of enrichment waste dispersion throughout adjacent areas. The amount of Hg entering environment with snowmelt water discharge was estimated. As a result of snowmelting, in 2014 the nearest to the dump site hydrographic network got Hg as 7.1 g with colloids and as 5880 g as particles. The results obtained allowed to assess the degree of Hg contamination of areas under the impact of metal enrichment industry. PMID- 29579680 TI - The antihistamine diphenhydramine is demethylated by anaerobic wastewater microorganisms. AB - While emerging pharmaceutical contaminants are monitored in wastewater treatment and the environment, there is little information concerning their microbial metabolites. The transformation of diphenhydramine by microorganisms in anaerobic digester sludge was investigated using anaerobic cultures amended with 1 mM diphenhydramine as the sole carbon source. Complete transformation of the parent compound to a persistent metabolite occurred within 191 days. Using GC/MS analysis, the metabolite was identified as N-desmethyl diphenhydramine. Loss of the parent compound diphenhydramine followed a first order rate constant of 0.013 day-1. There was no observed decrease in metabolite concentration even after a further 12 months of incubation, suggesting that the metabolite resists further degradation during wastewater treatment. Bacterial community diversity in the diphenhydramine transforming assay cultures showed enrichment in Comamonadaceae, Symbiobacteriaceae, Anaerolineaceae, and Prevotellaceae relative to unamended background controls. An anaerobic toxicity assay demonstrated that diphenhydramine has an inhibitory effect on both fermentative bacteria and methanogenic archaea in the wastewater community. In contrast, the metabolite N desmethyl diphenhydramine partially suppressed methanogens but did not impact the fermenting community. To our knowledge, this is the first report of diphenhydramine metabolism by a bacterial community. The limited transformation of diphenhydramine by wastewater microorganisms indicates that N-desmethyl diphenhydramine will enter the environment along with unmetabolized diphenhydramine.

AB - The role of azo dye Reactive Black 5 (RB5) as an electron donor and/or electron acceptor could be distinguished in dual chamber of photocatalytic fuel cell (PFC). The introduction of RB5 in anode chamber increased the voltage generation in the system since degradation of RB5 might produce electrons which also would transfer through external circuit to the cathode chamber. The removal efficiency of RB5 with open and closed circuit was 8.5% and 13.6%, respectively and removal efficiency for open circuit was low due to the fact that recombination of electron-hole pairs might happen in anode chamber since without connection to the cathode, electron cannot be transferred. The degradation of RB5 in cathode chamber with absence of oxygen showed that electrons from anode chamber was accepted by dye molecules to break its azo bond. The presence of oxygen in cathode chamber would improve the oxygen reduction rate which occurred at Platinum-loaded carbon (Pt/C) cathode electrode. The Voc, Jsc and Pmax for different condition of ultrapure water at cathode chamber also affected their fill factor. The transportation of protons to cathode chamber through Nafion membrane could decrease the pH of ultrapure water in cathode chamber and undergo hydrogen evolution reaction in the absence of oxygen which then increased degradation rate of RB5 as well as its electricity generation.

AB - As surrogates of polybrominated diphenyl ethers (PBDEs), new flame retardants (NFRs) include a series of chlorinated and brominated flame retardants. Though the NFRs are thought to induce similar thyroid hormone (TH) disrupting effects as PBDEs, few studies have focused on them. Given the increasing levels of NFRs in the environment, more in depth investigation of the potential TH disrupting effects of NFRs is warranted. This research involved a health survey to collect data and examine the associations between PBDEs, NFRs and TH. 174 school students lived near a petrochemical complex in South China participated in the survey, completing questionnaires and providing blood samples. Thirteen congeners of PBDEs, eight species of NFRs, TH and thyroid-stimulating hormone (TSH) were measured. The median levels of SigmaPBDE (sum of thirteen congeners of PBDEs) and SigmaNFR (sum of eight species of NFRs) for students were 140 and 240 ng g-1 lipid, respectively. Nonmonotonic relationships were observed between quartile levels of PBDEs, NFRs and corresponding TH. In contrast to SigmaPBDE that was positively associated with triidothyrine (T3) level, SigmaNFR was not statistically associated with TH. SigmaPBDE + NFR (sum of thirteen congeners of PBDEs and eight species of NFRs) was significantly associated with T3 level.

AB - Bioaccumulation of mercury and methylmercury in fish represents a serious risk to human beings. Extreme climate events like droughts may increase the trophic transfer of contaminants and net methylation of mercury. The present study assessed the influence of the 2014 drought on total mercury and methylmercury levels in fish from the lower Paraiba do Sul river basin. Contaminant levels were compared for Pimelodus fur, Pachyurus adspersus, Pimelodella lateristriga, Oligosarcus hepsetus, and Crenicichla lacustris captured in five sites in 2013 (N = 212) and 2014 (N = 231). The results indicate that levels of contaminants were higher during the drought in most species. Rainfall was weakly and negatively correlated with total mercury levels in most of the species. The weak relationship between these two variables was due to the indirect influence of rainfall on mercury bioaccumulation. In summary, drought increased the levels of two contaminants in fish. PMID- 29579684 TI - Insecticides alter prey choice of potential biocontrol agent Philodromus cespitum (Araneae, Philodromidae). AB - Even though pesticides can have various sublethal effects on behaviour of biocontrol agents, no study to date has investigated the effects of pesticides on the prey choice of generalist predators. Prey choice of generalist predators is among key factors determining the predation pressure they exert on pests, because it influences fitness of predators and consequently their densities and per capita capture rate. Here, we investigated the effect of Integro (a.i. methoxyfenozide) and SpinTor 480 Sc (a.i. spinosad) on prey choice and predatory activity of the spider Philodromus cespitum, which is known significantly to reduce hemipteran and dipteran pests in fruit orchards. We compared the prey preferences of philodromids between the psyllid pest Cacopsylla pyri (Hemiptera, Psyllidae) and beneficial Theridion sp. spiders in laboratory experiments. We found that both pesticides altered the prey preferences of philodromids. While the philodromids in a control treatment preferred theridiid spiders over the psyllid pest, philodromids in the pesticide treatments exhibited no significant prey preferences. The changes in prey preferences were caused by increased predation on the psyllids, while the predation on the theridiid remained similar. We suggest that the changes in prey preferences might theoretically be due to 1) impaired sensory systems, 2) altered taste, and/or 3) altered mobility. In combination with other studies finding reduced predation on fruit flies in P. cespitum after exposure to SpinTor, our results indicate that the sublethal effects of pesticides on predatory behaviour of generalist predators can depend on prey type and/or prey community composition. PMID- 29579685 TI - Impact of insulin signaling and proteasomal activity on physiological output of a neuronal circuit in aging Drosophila melanogaster. AB - The insulin family of growth factors plays an important role in development and function of the nervous system. Reduced insulin and insulin-growth-factor signaling (IIS), however, can improve symptoms of neurodegenerative diseases in laboratory model organisms and protect against age-associated decline in neuronal function. Recently, we showed that chronic, moderately lowered IIS rescues age related decline in neurotransmission through the Drosophila giant fiber escape response circuit. Here, we expand our initial findings by demonstrating that reduced functional output in the giant fiber system of aging flies can be prevented by increasing proteasomal activity within the circuit. Manipulations of IIS in neurons can also affect longevity, underscoring the relevance of the nervous system for aging. PMID- 29579686 TI - Cerebral microhemorrhages due to traumatic brain injury and their effects on the aging human brain. AB - Although cerebral microbleeds (CMBs) are frequently associated with traumatic brain injury (TBI), their effects on clinical outcome after TBI remain controversial and poorly understood, particularly in older adults. Here we (1) highlight major challenges and opportunities associated with studying the effects of TBI-mediated CMBs; (2) review the evidence on their potential effects on cognitive and neural outcome as a function of age at injury; and (3) suggest priorities for future research on understanding the clinical implications of CMBs. Although TBI-mediated CMBs are likely distinct from those due to cerebral amyloid angiopathy or other neurodegenerative diseases, the effects of these 2 CMB types on brain function may share common features. Furthermore, in older TBI victims, the incidence of TBI-mediated CMBs may approximate that of cerebral amyloid angiopathy-related CMBs, and thus warrants detailed study. Because the alterations effected by CMBs on brain structure and function are both unique and age-dependent, it seems likely that novel, age-tailored therapeutic approaches are necessary for the adequate clinical interpretation and treatment of these ubiquitous and underappreciated TBI sequelae. PMID- 29579688 TI - Cluster analysis of autism spectrum disorder symptomatology: Qualitatively distinct subtypes or quantitative degrees of severity of a single disorder? AB - The decision to collapse several related disorders into a single diagnosis of Autism Spectrum Disorder (ASD) generated significant controversy and debate. There has been mixed evidence as to whether various ASD subtypes are qualitatively distinct or if they exist on a spectrum of symptom severity. The present study conducted a two-step cluster analysis of major ASD symptoms in a sample of 147 young males with ASD aged between 6yr and 18yr with IQ > 70. Results indicated that a two-cluster solution (high and low severity of ASD symptomatology) was reliable and valid. Further, the construct of challenging behaviour was not a necessary component of the two-cluster solution, verifying the new conceptualisation of ASD. Further replication of these findings with other subsets of individuals with ASD is needed. PMID- 29579689 TI - Improved production of isobutanol in pervaporation-coupled bioreactor using sugarcane bagasse hydrolysate in engineered Enterobacter aerogenes. AB - A process of isobutanol production from sugarcane bagasse hydrolysates in Enterobacter aerogenes was developed here with a pervaporation-integrated procedure. Isobutanol pathway was overexpressed in a mutant strain with eliminated byproduct-forming enzymes (LdhA, BudA, and PflB). A glucose-and-xylose coconsuming ptsG mutant was constructed for effective utilization of lignocellulosic biomass. Toxic effects of isobutanol were alleviated by in situ recovery via a pervaporation procedure. Compared to single-batch fermentation, cell growth and isobutanol titer were improved by 60% and 100%, respectively, in the pervaporation-integrated fermentation process. A lab-made cross-linked polydimethylsiloxane membrane was cast on polyvinylidene fluoride and used in the pervaporation process. The membrane-penetrating condensate contained 55-226 g m-2 h-1 isobutanol with 6-25 g L-1 ethanol after separation. This study offers improved fermentative production of isobutanol from lignocellulosic biomass with a pervaporation procedure. PMID- 29579687 TI - Deuterated polyunsaturated fatty acids reduce brain lipid peroxidation and hippocampal amyloid beta-peptide levels, without discernable behavioral effects in an APP/PS1 mutant transgenic mouse model of Alzheimer's disease. AB - Alzheimer's disease (AD) involves progressive deposition of amyloid beta-peptide (Abeta), synapse loss, and neuronal death, which occur in brain regions critical for learning and memory. Considerable evidence suggests that lipid peroxidation contributes to synaptic dysfunction and neuronal degeneration, both upstream and downstream of Abeta pathology. Recent findings suggest that lipid peroxidation can be inhibited by replacement of polyunsaturated fatty acids (PUFA) with isotope-reinforced (deuterated) PUFA (D-PUFA), and that D-PUFA can protect neurons in experimental models of Parkinson's disease. Here, we determined whether dietary D-PUFA would ameliorate Abeta pathology and/or cognitive deficits in a mouse model of AD (amyloid precursor protein/presenilin 1 double mutant transgenic mice). The D-PUFA diet did not ameliorate spatial learning and memory deficits in the AD mice. Compared to mice fed an hydrogenated-PUFA control diet, those fed D-PUFA for 5 months exhibited high levels of incorporation of deuterium into arachidonic acid and docosahexaenoic acid, and reduced concentrations of lipid peroxidation products (F2 isoprostanes and neuroprostanes), in the brain tissues. Concentrations of Abeta40 and Abeta38 in the hippocampus were significantly lower, with a trend to reduced concentrations of Abeta42, in mice fed D-PUFA compared to those fed hydrogenated-PUFA. We conclude that a D-PUFA diet reduces the brain tissue concentrations of both arachidonic acid and docosahexaenoic acid oxidation products, as well as the concentration of Abetas. PMID- 29579691 TI - Microbial communities underpinning mesophilic anaerobic digesters treating food wastewater or sewage sludge: A full-scale study. AB - Ten mesophilic full-scale anaerobic digesters treating food wastewater (FW digesters) or sewage sludge (SL-digesters) were monitored for 1 year to investigate: (1) microbial communities underpinning FW-digesters and SL digesters, (2) the effects of total ammonia-nitrogen concentration [TAN] and Na+ concentration [Na+] on variations of these communities. [TAN] and [Na+] in the digester varied among digesters: 1.7-6.5 g TAN/L and 1.0-3.6 g Na+/L for the FW digesters, and 0.1-2.2 g TAN/L and 0.1-1.2 g Na+/L for the SL-digesters; [TAN] negatively correlated with the process efficiency of the FW-digesters. Microbial communities were less diverse in the FW-digesters than in the SL-digesters. The FW- and SL-digesters formed very distinct microbial community structures; [TAN] and [Na+] in the digester were the critical factors shaping these structures. Immigrant bacteria from influent sludge significantly influence the bacterial communities of the SL-digesters. Methanoculleus might be tolerant to high ammonia in AD of such organic wastewater. PMID- 29579690 TI - A novel approach to developing a reusable marine macro-algae adsorbent with chitosan and ferric oxide for simultaneous efficient heavy metal removal and easy magnetic separation. AB - Chitosan modified magnetic kelp biochar (Chi-KBm) was successfully synthesized for efficient removal of heavy metals (Cu2+) from wastewater. Interestingly, the characterization results indicated that Chi-KBm showed 6 times higher surface area (6.17 m2/g) than the pristine magnetic kelp biochar KBm (0.97 m2/g). In addition, new functional groups, such as NH and CN group, have been created on the surface of biochar as a result of chitosan modification process, which in turns led to improve the Cu2+ adsorption capacity. The effect of pH and chitosan loading on heavy metal adsorption, and competition reaction of different metal ions adsorption were also investigated. Chi-KBm exhibited a separation efficiency of more than 99.8%, which allows to recovery and reusability of the adsorbent material and heavy metals simultaneously. Overall, this study highlighted the Chi KBm is a promise adsorbent for heavy metal removal without sacrificing of the separation ability using magnetism. PMID- 29579692 TI - Prostate-specific antigen (PSA) as a possible biomarker in non-prostatic cancer: A review. AB - Prostate-specific antigen (PSA) is a serine protease produced by epithelial prostatic cells and its main function is to liquefy seminal coagulum. Currently, PSA is a biomarker for the diagnosis and screening of prostate cancer and it was the first cancer biomarker approved by the FDA. The quantity and serum isoforms of male PSA, allows distinguishing between carcinoma and benign inflammatory disease of the prostate. Initially, it was thought that PSA was produced only by the prostate, and thus, a protein that was expressed exclusively in men. However, several authors report that PSA is a protein that is expressed by multiple non prostatic tissues not only in men but also in women. Some authors also report that in women, the expression of this protein is highly related to breast and colon cancer and therefore can act as a possible biomarker for early detection, diagnosis and prognosis of these cancers in women. In this review, we will focus on the characteristics of the PSA at a molecular level, its current clinical implications, the expression of this protein in non-prostatic tissues, and its relationship with cancer, especially in women. PMID- 29579693 TI - Secretins revealed: structural insights into the giant gated outer membrane portals of bacteria. AB - The acquisition and evolution of customized and often highly complex secretion systems allows Gram-negative bacteria to efficiently passage large macromolecules across both inner and outer membranes and, in some cases, that of the infected host. Essential to the virulence and ultimate survival of the many pathogenic species that encode them, secretion systems export a wide variety of effector proteins and DNA as well as the downstream extracellular filaments of the secretion apparatus themselves. Although these customized secretion systems differ in their cytosolic and inner membrane components, several commonly rely on the secretin family of giant pores to allow these large substrates to traverse the outer membrane. Recently, several near-atomic resolution cryo-EM secretin structures have unveiled the first insights into the unique structural motifs required for outer membrane localization, assembly, hallmark ultrastable nature, spontaneous membrane insertion, and mechanism of action-including the requisite central gating needed to prevent deleterious passage of periplasmic contents to the extracellular space. PMID- 29579694 TI - Translocation of lipoproteins to the surface of gram negative bacteria. AB - The surface of many Gram-negative bacteria contains lipidated protein molecules referred to as surface lipoproteins or SLPs. SLPs play critical roles in host immune evasion, nutrient acquisition and regulation of bacterial stress response, and have been extensively studied as vaccine antigens. The aim of this review is to summarize the recent studies that have investigated the biosynthetic and translocation pathways used by different bacterial species to deliver SLPs to the surface. We will specifically focus on Slam, a novel outer membrane protein first discovered in pathogenic Neisseria sp., that is involved in translocation of SLPs across the outer membrane. PMID- 29579695 TI - 'They'll be judging us' a qualitative study of pregnant women's experience of being offered participation in a supportive intervention. AB - OBJECTIVE: to explore pregnant women's experience of being offered participation in a supportive intervention and how their experience influenced the outcome of the intervention. DESIGN AND SETTING: a qualitative, phenomenological hermeneutic study based on semi-structured interviews with eight Danish first-time mothers. FINDINGS: the study revealed a divergence between the professional's and the women's perception of their vulnerability. The women typically felt the offer of participation as a stigma, which they met with anxiety and confusion. Insufficient information led to uncertainty and a feeling of being evaluated as inadequate mothers or parents. The information offered failed to provide the basis of informed choice. However, the development of a trusting, supportive and non-judgemental relationship with the health professionals ensured most women a positive outcome of the intervention. KEY CONCLUSION: being invited to participate in an intervention targeting vulnerable women may induce unintended feelings in relation to stigmatization and judgement, leading to doubt about own ability to cope with motherhood. Inadequate information and explication about aims and contents of the intervention are likely to cause confusion and anxiety and a feeling of being judged as parents. Information combined with establishing a trusting and non-judgemental relationship between women and professionals appears to have significant impact on outcomes. IMPLICATIONS FOR PRACTICE: care providers should be aware of the induced negative feelings and sense of judgement and stigmatization as a result of being categorized as vulnerable and perceived in need of help to cope with motherhood, and that they may play a key role in helping women cope with this. Furthermore, detailed information about the intervention and the background of the offer should be ensured as well as an informed choice of participation. PMID- 29579696 TI - Support for pregnant women identified with fear of childbirth (FOC)/tokophobia - A systematic review of approaches and interventions. AB - BACKGROUND: providing appropriate care for pregnant women with high or severe fear of childbirth (FOC) is a challenge in midwifery care today. FOC is associated with predisposing anamnestic factors, various sociodemographic and psychosocial characteristics, and may result in serious healthrelated consequences. It is therefore important to establish which interventions may increase a woman's faith in her own ability to cope with labour and birth. AIM: to systematically identify and review studies examining interventions for relief of severe fear of childbirth in pregnancy and their underlying conceptual foundation. METHODS: a systematic literature search was performed following Cochrane Collaboration and PRISMA Statement recommendations. Inclusion criteria were: studies including pregnant women diagnosed with high or severe FOC or who requested a caesarean section due to severe FOC, studies (regardless of design) observing the effect of an intervention addressing FOC, and studies published in English. Publications addressing anxiety or stress were excluded. 377 references were screened by title and abstract. The risk of bias was assessed. FINDINGS: 19 articles referring to 15 research projects were included in the analysis. The studies show heterogeneity regarding assessment methods, type, conceptualisation and application of interventions. There is evidence that both cognitive therapy sessions and a theory-based group psychoeducation with relaxation are effective interventions. KEY CONCLUSIONS: despite methodological limitations, single or group psychoeducation sessions for nulliparous women or therapeutic conversation during pregnancy (in group or individual sessions) have the potential to strengthen women's self-efficacy and decrease the number of caesarean sections due to FOC. The theoretical validation of an intervention deepens the understanding of psychological processes in women coping with severe FOC. IMPLICATIONS FOR PRACTICE: theory-based concepts of care for both antenatal and intrapartum support of pregnant women with high or severe FOC should be developed, piloted, tested, evaluated and implemented within the given healthcare system. Midwives need to be competent to address pregnant women's fears regarding labour and birth in antenatal care. The use of a valid assessment tool to identify the level of FOC in women, even if they do not raise the issue, is recommended in routine antenatal care so that appropriate expert support can be offered. A one-on-one conversation may be feasible for those women unwilling to fill in a questionnaire. Cooperative local networks between midwives, psychologists and obstetricians qualified in psychotherapy should be established to ensure timely and effective care for women with high or severe FOC. PMID- 29579697 TI - Neighborhood social and economic change and retail food environment change in Madrid (Spain): The heart healthy hoods study. AB - This study explores the association between neighborhood social and economic change from 2009 to 2013 and changes in the retail food environment from 2013 to 2017 in Madrid (Spain). We classified neighborhoods into four types: decreasing SES, new housing/gentrifying, increasing SES, and aging (population and housing). Food store data was obtained from a retail spaces census and classified as supermarket, specialized small store, or fruit and vegetable store. Compared to aging areas, new housing/gentrifying and areas with increasing SES had a higher baseline presence and proportion of supermarkets and a lower proportion of specialized stores and fruit and vegetable stores. Areas with decreasing SES had an initially higher presence and proportion of fruit and vegetable stores but showed a declining trend in both presence and proportion of fruit and vegetable stores. PMID- 29579698 TI - Understanding temporal change of spatial accessibility to healthcare: An analytic framework for local factor impacts. AB - Population demand, health service supply, and the linkages between them (e.g., transport infrastructure) are important factors that determine spatial accessibility to healthcare at a place. These three factors vary differently over time and location, leading to temporal changes and spatial disparities in access to healthcare. Few analytic methods have been developed to measure local impacts of these factors on healthcare accessibility over time, which are essential to alleviating health disparities and evaluating intervention programs. We propose a spatially explicit analytic framework to measure local factor impacts over time by adopting a chain substitution method from economics. The analysis is illustrated by a case study of spatial accessibility to physicians in Florida, USA, from 1990 to 2010. For each census block group, the results show the impact of local population change, physician relocation, and road-network expansion on the loss and gain of healthcare accessibility over time. The leading impact factor are identified for each census block group through comparison, and spatial clusters of factor impacts are discovered. To the literature of healthcare accessibility, this article presents a promising start of factor impact analysis and offers new perspectives in exploring spatial processes underlying people's access to healthcare. PMID- 29579699 TI - Social cohesion and self-rated health among adults in South Africa: The moderating role of race. AB - In African countries including South Africa, the nexus between social cohesion and health remains under-researched. Using data from the 2012 South African social attitudes survey with a sample of 1988 adults in South Africa aged 18 years or older, we used the collective efficacy theory by Sampson and colleagues to examine the relationship between social cohesion and self-rated health in an African sample. We also examined how this relationship differed by race. Results from the multivariate analysis after adjusting for covariates suggested that adults in the highest tertile of social cohesion were more likely to report moderate or good health compared to those in the lowest tertile. Sub-group analysis provided no evidence that the relationship was moderated by race. These findings corroborate prior evidence that social cohesion is important for improving the health of adults. PMID- 29579700 TI - The associations between interpersonal violence and psychological distress among rural and urban young women in South Africa. AB - BACKGROUND: Approximately 25% of the world's population consists of young people. The experience of violence peaks during adolescence and the early adult years. A link between personal experience of violence and mental health among young people has been demonstrated but rural-urban differences in these associations are less well known in low to middle income countries. The aim of this study was to investigate the associations between interpersonal violence and psychological distress among rural and urban young women. METHODS: Data on experiences of violence and psychological distress were collected from a total of 926 non pregnant young women aged between 18 and 22 years of age in rural and urban sites in South Africa. The General Health Questionnaire-28 was used to assess psychological distress as an indicator of mental health. Generalised structural equation models were employed to assess potential pathways of association between interpersonal violence and psychological distress. RESULTS: Thirty-four percent of the urban young women (n = 161) reported psychological distress compared to 18% of rural young women (n = 81). In unadjusted analysis, exposure to interpersonal violence doubled the odds of psychological distress in the urban adolescents and increased the odds 1.6 times in the rural adolescents. In adjusted models, the relationship remained significant in the urban area only (OR 1.84, 95% CI 1.13-3.00). Rural residence seemed protective against psychological distress (OR 0.41, 95% CI 0.24-0.69). Structural equation modelling did not reveal any direct association between exposure to interpersonal violence and psychological distress among rural young women. Stressful household events were indirectly associated with psychological distress, mediated by violence among young women in the urban area. CONCLUSION: The relationship between violence and psychological distress differs between urban and rural-residing young women in South Africa, and is influenced by individual, household and community (contextual) factors. PMID- 29579701 TI - Gait deviations in Duchenne muscular dystrophy-Part 1. A systematic review. AB - BACKGROUND: Although prolonged ambulation is considered important in children with Duchenne muscular dystrophy (DMD), articles describing gait deviations in DMD are scarce. RESEARCH QUESTION: Therefore, our research questions were the following: 1) what are the most consistently reported spatiotemporal-, kinematic , kinetic-, and muscle activity deviations in children with DMD in literature, 2) what is the quality of the studies describing these deviations, and 3) is there need for further research? METHODS: We conducted a systematic literature search for studies published before the end of June 2017 in six online databases. We created a data extraction form to define information on materials and methods and on the analyzed gait parameters for each paper included in the review. If enough information was available, we calculated standardized mean differences (SMDs). RESULTS: The search yielded nine articles, but generalizability was poor. Seventy nine parameters were analyzed by seven research groups, but they only agreed on a decrease in walking speed (minimal SMD: 1.26), stride length (1.83), step length (1.80), dorsiflexion during swing (1.43), maximal power generation at the hip (0.92), maximal knee extension torque (0.99), maximal dorsiflexion torque ( 1.30), and maximal power generation at the ankle (0.92), and an increased knee range of motion (-0.82) in DMD. SIGNIFICANCE: In order to keep children with DMD ambulant as long as possible, a clear understanding of their pathological gait pattern is necessary. However, gait deviations in DMD appear not well defined. Previous studies appear to be of an exploratory nature while using predefined gait parameters to assess an undirected null hypothesis. This made them prone to regional focus bias, thereby increasing the chance of a type I error. Therefore, further research is required to define the altered gait pattern in children with DMD. PMID- 29579702 TI - Gait and footwear in children and adolescents with Charcot-Marie-Tooth disease: A cross-sectional, case-controlled study. AB - OBJECTIVE: Children with Charcot-Marie-Tooth disease (CMT) report problems with gait and footwear. We evaluated differences in spatio-temporal gait variables and gait variability between children with CMT and typically developing (TD) children, and investigated the effect of footwear upon gait. METHOD: A cross sectional study of 30 children with CMT and 30 age- and gender-matched TD children aged 4-18 years. Gait was assessed at self-selected speed on an electronic walkway while barefoot and in two types of the child's own footwear; optimal (e.g., athletic-type runners) and suboptimal (e.g., flip-flops). RESULTS: Children with CMT walked more slowly (mean (SD) -13.81 (3.61) cm/s), with shorter steps (-6.28 (1.37) cm), wider base of support (+2.47 (0.66) cm; all p < 0.001) and greater base of support variability (0.48 (0.15) cm, p = 0.002) compared to TD children. Gait was faster in optimal footwear than suboptimal (-7.55 (1.31) cm/s) and barefoot (-7.42 (1.07) cm/sec; both p < 0.001) in the combined group of children. Gait in suboptimal footwear was more variable compared to barefoot and optimal footwear. Greater base of support variability and reduced balance was moderately correlated for both groups (CMT and TD). CONCLUSION: Gait is slower with shorter, wider steps and greater base of support variability in children with CMT. Poor balance is associated with greater base of support gait variability. Suboptimal footwear negatively affects gait in all children (CMT and TD), which has clinical implications for children and adolescents with CMT who have weaker feet and ankles, and poor balance. PMID- 29579703 TI - Backbone amide 15N chemical shift tensors report on hydrogen bonding interactions in proteins: A magic angle spinning NMR study. AB - Chemical shift tensors (CSTs) are an exquisite probe of local geometric and electronic structure. 15N CST are very sensitive to hydrogen bonding, yet they have been reported for very few proteins to date. Here we present experimental results and statistical analysis of backbone amide 15N CSTs for 100 residues of four proteins, two E. coli thioredoxin reassemblies (1-73-(U-13C,15N)/74-108-(U 15N) and 1-73-(U-15N)/74-108-(U-13C,15N)), dynein light chain 8 LC8, and CAP-Gly domain of the mammalian dynactin. The 15N CSTs were measured by a symmetry-based CSA recoupling method, ROCSA. Our results show that the principal component delta11 is very sensitive to the presence of hydrogen bonding interactions due to its unique orientation in the molecular frame. The downfield chemical shift change of backbone amide nitrogen nuclei with increasing hydrogen bond strength is manifested in the negative correlation of the principal components with hydrogen bond distance for both alpha-helical and beta-sheet secondary structure elements. Our findings highlight the potential for the use of 15N CSTs in protein structure refinement. PMID- 29579704 TI - Chitooligosaccharide: An evaluation of physicochemical and biological properties with the proposition for determination of thermal degradation products. AB - Being the most versatile biopolymer, chitooligosaccharide/chitosan oligosaccharide (COS) has been extensively studied for a range of exceptional biological activities and potential developments of novel medical devices and systems in biomedical and pharmaceutical fields. While possessing intrinsic biocompatibility, mucoadhesiveness, and non-toxicity it gained more interests in the biomedical development of novel systems, devices, and pharmaceutical formulations. The bioactive relativity of chitosan and COS are of highly significant and thus explored in this paper while highlighting its multiple biological activities and promising biomedical applications. More emphasis is on the molecular weight, degree of acetylation/deacetylation, degree of polymerization and reactive groups in relation to chitin and chitosan. Despite COS wide acceptance and utilization, the associated viscosity and instability are crucial factors that posed a great challenge to researchers. The apparent reason attributed to instability and viscosity could be the presence intrinsic variable oligomers within COS. Due to lack of data on safety and impurity analysis of thermal exposure of COS, we hypothesized that different molecules could be generated with thermal treatment of COS, thus finally suggested a prospective determination of thermal degradation product(s)in COS. Hence the aim of this paper is to highlight COS physicochemical and biological significance with reference to its recent developments and propose a further chemical analysis thermal treated COS. This could trigger future researchers for possible isolation and characterization of distinct biomolecules from COS. PMID- 29579705 TI - LncRNA SNHG6 acts as a prognostic factor to regulate cell proliferation in glioma through targeting p21. AB - It has been certified that long noncoding RNAs (lncRNAs) are crucial regulators in the progression of various human cancers. snoRNA host gene 6 (SNHG6) has been uncovered to affect the initial stage and tumorigenesis of hepatocellular carcinoma. Nevertheless, the expression pattern and biological role of SNHG6 in glioma still need to be investigated. The study aims to investigate the expression pattern, biological role and the potential mechanism of SNHG6 in glioma. In this study, the high expression of SNHG6 was tested in both glioma tissues and glioma cells. The correlation between expression levels of SNHG6 and the overall survival of glioma patients was demonstrated by using Kaplan Meier method analysis. Next, gain of function assays revealed that overexpression of SNHG6 can promote the formation of malignant phenotype of 1800 cell. However, results of loss-of-function assays revealed that silenced SNHG6 exerted the inhibitory function on glioma cell growth. Flow cytometric analysis was performed in glioma cells to detect the anti-oncogenic effects of silenced SNHG6 on cell cycle and apoptosis. Finally, we identified that p21 was involved in glioma cell proliferation after SNHG6 was downregulated. Taken together, we concluded that SNHG6 is a regulator and a potential therapeutic target in glioma. PMID- 29579706 TI - Molecular basis of vascular damage caused by cigarette smoke exposure and a new approach to the treatment: Alpha-linolenic acid. AB - Exposure to cigarette smoke (CS) causes vessel damage and mechanism of this damage has not yet been clearly identified. Therefore, in this study we aimed to investigate whether vessel damage due to the CS exposure will be prevented by the alpha-linolenic acid (ALA) or not which has anti-inflammatory effect in mice. For this reason, mice were grouped as controls (with and without CS) and ALA (with and without CS). The CS application continued 5 days a week for two months. At the end of two months, the mice were killed by cervical dislocation and their blood and thoracic aortas were isolated. ALA Treatment increased acetylcholine relaxations. CS decreased acetylcholine relaxation. CS with ALA treatment increased acetylcholine relaxations versus just CS treatment. CS caused rising in cyclooxigenase-2 and phospholipase A2 levels. This rise is inhibited with ALA treatment. CS decreased eNOS levels. But this result was not statistically significant. Furthermore, according to electron microscopic study CS damaged both smooth muscle and endothelium. While ALA treatment prevented smooth muscle damage it didn't prevent endothelial damage. Using cigarette and CS exposure is a risk factor for cardiovascular disease. Our study showed that this disease.

AB - As a phenylpropanoid and dibenzylbutyrolactone lignan present in medical plants, such as those used in traditional Chinese herbal medicine, including Arctium lappa (Niubang), arctigenin exhibits antimicrobial, anti-inflammatory, and anticancer activities. In this study, we investigated the protective role of arctigenin in Concanavalin A (ConA)-induced acute hepatitis in mice. Arctigenin remarkably reduced the congestion and necroinflammation of livers, and improved hepatic function (ALT and AST) in ConA-induced acute hepatitis in vivo. The infiltration of CD4 T, NKT and macrophages into the livers was found to be reduced with arctigenin treatment. Arctigenin suppressed ConA-induced T lymphocyte proliferations that might have resulted from enhanced IL-10 production by macrophages and CD4 T cells. These results suggested that arctigenin could be a powerful drug candidate for acute hepatitis through immune suppression. PMID- 29579708 TI - Punicalagin ameliorates the elevation of plasma homocysteine, amyloid-beta, TNF alpha and apoptosis by advocating antioxidants and modulating apoptotic mediator proteins in brain. AB - The present study investigated the neuroprotective role of punicalagin, a major polyphenolic compound of pomegranate on methionine-induced brain injury. Hyperhomocysteinemia (HHcy) was induced in two months old male BALB c mice by methionine supplementation in drinking water (1 g/kg body weight) for 30 days. Punicalagin (1 mg/kg) was injected i.p every other day concurrently with methionine. Punicalagin significantly prevented the rise in the levels of homocysteine, amyloid-beta and TNF-alpha. HHcy is associated with a decrease in the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (PGx) and glutathione reductase (GR) and glutathione (GSH) levels in the brains of methionine-treated mice while these antioxidants are increased by punicalagin supplementation. The treatment with punicalagin significantly decreased oxidative stress as indicated by decreased malondialdehyde and protein carbonyl formation in the brain. Compared with methionine-treated animals, mice that treated with methionine and punicalagin remarkably displayed less apoptosis, indicated by the lower level of proapoptotic protein (Bax, caspases- 3, 9 and p53) and higher levels of antiapoptotic Bcl-2 protein than those in hyperhomocysteinemic mice. The potent bioactivity of punicalagin extends to protect neuronal DNA as evidenced by the inhibition of the increase of comet parameters compared to the methionine-treated mice. In conclusion, punicalagin protected from methionine-induced HHcy and brain damage with an ability to repress apoptosis by modulating apoptotic mediators and maintaining DNA integrity in the brain of mice. PMID- 29579709 TI - The novel piperazine-containing compound LQFM018: Necroptosis cell death mechanisms, dopamine D4 receptor binding and toxicological assessment. AB - Piperazine is a promising scaffold for drug development due to its broad spectrum of biological activities. Based on this, the new piperazine-containing compound LQFM018 (2) [ethyl 4-((1-(4-chlorophenyl)-1H-pyrazol-4-yl)methyl)piperazine-1 carboxylate] was synthetized and some biological activities investigated. In this work, we described its ability to bind aminergic receptors, antiproliferative effects as well as the LQFM018 (2)-triggered cell death mechanisms, in K562 leukemic cells, by flow cytometric analyses. Furthermore, acute oral systemic toxicity and potential myelotoxicity assessments of LQFM018 (2) were carried out. LQFM018 (2) was originally obtained by molecular simplification from LASSBio579 (1), an analogue compound of clozapine, with 33% of global yield. Binding profile assay to aminergic receptors showed that LQFM018 (2) has affinity for the dopamine D4 receptor (Ki = 0.26 MUM). Moreover, it showed cytotoxicity in K562 cells, in a concentration and time-dependent manner; IC50 values obtained were 399, 242 and 119 MUM for trypan blue assay and 427, 259 and 50 MUM for MTT method at 24, 48 or 72 h, respectively. This compound (427 MUM) also promoted increase in LDH release and cell cycle arrest in G2/M phase. Furthermore, it triggered necrotic morphologies in K562 cells associated with intense cell membrane rupture as confirmed by Annexin V/propidium iodide double-staining. LQFM018 (2) also triggered mitochondrial disturb through loss of DeltaPsim associated with increase of ROS production. No significant accumulation of cytosolic cytochrome c was verified in treated cells. Furthermore, it was verified an increase of expression of TNF-R1 and mRNA levels of CYLD with no involviment in caspase-3 and -8 activation and NF-kappaB in K562 cells. LQFM018 (2) showed in vitro myelotoxicity potential, but it was orally well tolerated and classified as UN GHS category 5 (LD50 > 2000-5000 mg/Kg). Thus, LQFM018 (2) seems to have a non selective action considering hematopoietic cells. In conclusion, it is suggested LQFM018 (2) promotes cell death in K562 cells via necroptotic signaling, probably with involvement of dopamine D4 receptor. These findings open new perspectives in cancer therapy by use of necroptosis inducing agents as a strategy of reverse cancer cell chemoresistance. PMID- 29579710 TI - Bu-shen-zhu-yun decoction promotes synthesis and secretion of FSHbeta and LHbeta in anterior pituitary cells in vitro. AB - Luteal phase defects (LPD) are an important etiology of infertility which has increased in recent years. Studies have shown that bu-shen-zhu-yun decoction (BSZY-D) can lower the expression of estrogen receptor and progesterone receptor, in rats endometrium of embryonic implantation period, which upregulated by mifepristone, and improve uterine receptivity. The aim of present study was to determine the effect of BSZY-D on the synthesis and secretion of gonadotropic hormones in the anterior pituitary cells of rats. Rats were treated with saline (control) or BSZY-D two times/day for three estrous cycles by gavage. The cerebrospinal fluid (CSF) were collected for further cell treatment. The components in BSZY-D, serum and CSF were analysed by High Performance Liquid Chromatography (HPLC). Cells were either pretreated with normal CSF or BSZY-D/CSF before being stimulated with or without cetrorelix. The mRNA and proteins levels of receptors, hormones, and transcription factors were detected by RT-PCR, western blot analysis and immunostaining. We show that non-toxic concentrations of cetrorelix, a GnRH antagonist, can reduce the mRNA and protein levels of GnRHR, LH, and FSH. This effect could be reversed by the addition of BSZY-D/CSF. We also show decreased mRNA and protein expression of transcription factors, such as CREB, and Egr-1 and secretory vescicles, including SNAP-25 and Munc-18 upon treatment with cetrorelix could be reversed post co-treatment with BSZY-D/CSF. These results indicate that BSZY-D/CSF treatment led to increased levels of GnRHR, transcription factors, and secretory vesicles leading to increased secretion of FSH and LH. Thus, BSZY-D presents a promising candidate to treat luteal phase defects and infertility. PMID- 29579711 TI - Osthole inhibits the PI3K/AKT signaling pathway via activation of PTEN and induces cell cycle arrest and apoptosis in esophageal squamous cell carcinoma. AB - Esophageal squamous cell carcinoma (ESCC) is one of the most common lethal tumors and is known to be lack of effective therapy. Thus, novel therapeutic strategies are greatly needed for treatment of ESCC. Osthole, a natural active extract, has been documented to have anti-tumor activity. However, the effect of osthole on ESCC cells has not been elucidated. In this study, we demonstrated that osthole could inhibit the ESCC cell proliferation in dose- and time-dependent manner. Osthole treatment also induced G2/M phase arrest and apoptosis of ESCC cells. Furthermore, upon exposure to osthole, the expression of Cyclin B1, Cdc2, Bcl-2, PARP1 and Survivin was decreased, while the expression of BAX, cleaved PARP1, cleaved Caspase3 and cleaved Caspase9 was increased. In addition, osthole treatment elicited upregulation of PTEN and downregulation of PI3K and phosphorylated AKT (p-AKT). Taken together, our study demonstrates that osthole could suppress ESCC proliferation through inducing cell cycle arrest and apoptosis. Moreover, PTEN-PI3K/AKT signaling pathway can be regulated by osthole. Our results indicate that osthole may find therapeutic application in the treatment of ESCC patients. PMID- 29579712 TI - Ginkgetin ameliorates experimental atherosclerosis in rats. AB - Atherosclerosis is a common disease seriously detrimental to human health. Natural products are important sources of therapeutic candidates for atherosclerosis. We here evaluated the effects of ginkgetin on experimental atherosclerosis in rats and explored the underlying mechanisms. Atherosclerosis was induced by high-fat diet for 12 weeks combined with single intraperitoneal injection of vitamin D3 in rats. The atherosclerotic rats were then treated with ginkgetin at 25, 50 and 100 mg/kg/d or simvastatin at 2 mg/kg/d for 8 weeks. Blood and thoracic aortas were collected for analyses of histopathology, lipid deposition, serum biochemistry, matrix metalloproteinases (MMPs), and nitric oxide (NO)/NO synthase (NOS) system. We found that ginkgetin improved thoracic aortic intima structure, reduced intima-media thickness and intima/media ratio, and attenuated lipid deposition in aorta of atherosclerotic rats. Ginkgetin also decreased the serum levels of total cholesterol, triglyceride and low-density lipoprotein cholesterol, but restored the serum levels of high-density lipoprotein cholesterol in atherosclerotic rats. Additionally, ginkgetin reduced the mRNA and protein expression of MMP-2 and MMP-9 in thoracic aortas of rats with atherosclerosis. Further examinations showed that ginkgetin increased the NO and NOS levels in serum and thoracic aortas. Ginkgetin also unregulated the expression of endothelial NOS and downregulated the expression of inducible NOS at both mRNA and protein levels in thoracic aortas of atherosclerotic rats. Altogether, ginkgetin showed therapeutic effects on experimental atherosclerosis associated with improving lipid profile and modulating the MMPs and NO/NOS systems in rats. Ginkgetin could be a promising candidate for the treatment of atherosclerosis. PMID- 29579714 TI - Two colorimetric and ratiometric fluorescence probes for hydrogen sulfide based on AIE strategy of alpha-cyanostilbenes. AB - Aggregation-induced emission (AIE) active fluorescent probes have attracted great potential in biological sensors. In this paper two cyanostilbene based fluorescence chemoprobe Cya-NO2 (1) and Cya-N3 (2) were developed and evaluated for the selective and sensitive detection of hydrogen sulfide (H2S). Both of these probes behave aggression-induced emission (AIE) activity which fluoresces in the red region with a large Stokes shift. They exhibit rapid response to H2S with enormous colorimetric and ratiometric fluorescent changes. They are readily employed for assessing intracellular H2S levels. PMID- 29579713 TI - Mesoscale connectomics. AB - Brain cells communicate with one another via local and long-range synaptic connections. Structural connectivity is the foundation for neural function. Brain wide connectivity can be described at macroscopic, mesoscopic and microscopic levels. The mesoscale connectome represents connections between neuronal types across different brain regions. Building a mesoscale connectome requires a detailed understanding of the cell type composition of different brain regions and the patterns of inputs and outputs that each of these cell types receives and forms, respectively. In this review, I discuss historical and contemporary tracing techniques in both anterograde and retrograde directions to map the input and output connections at population and individual cell levels, as well as imaging and network analysis approaches to build mesoscale connectomes for mammalian brains. PMID- 29579716 TI - Special feature of kinetics of ZcE isomerization of beta-N-methylaminovinyl trifluoromethyl ketone in Ar matrix exposed to UV radiation and spontaneous E?Z isomerization of alpha-methyl-beta-N-methylaminovinyl trifluoromethyl ketone. AB - Although it is well known that reactivity of alpha,beta-unsaturated enaminoketones is closely associated with spatial and electronic structure but until now little attention was devoted to quantitative investigation of interconversion of different stereoisomeric forms of enaminoketones. In present work we studied peculiarities of kinetics of Z?E isomerization of enaminoketone 4 (N-methylamino)-1,1,1-trifluorobut-3-en-2-one F3C-COCHCHNH(CH3) (1) in Ar-matrix exposed to UV-radiation (lambda=340nm) with IR Fourier and 2D correlation spectroscopy and we found that Z-s-Z-s-trans isomer transforms primarily into two E-isomers, E-s-E-s-trans and E-s-Z-s-trans which further turn into the E-s-E-s cis and E-s-Z-s-cis conformers all interconversion rate constants being comparable in magnitude. Along with this process long-term exposure to the UV radiation results in proton transfer from nitrogen of methylamino group to carbonyl oxygen with simultaneous isomerization of 'cyclic' iminoenol form into 'linear'one. In solution of enaminoketone 4-(N-methylamino)-1,1,1-trifluoro-3 methylbut-3-en-2-one F3C-CO-C(CH3)CH-NH(CH3) (2) we observed reversed process, namely, spontaneous interconversion of the E-s-E-s-trans and E-s-Z-s-trans conformers into the Z-s-Z-trans isomer. It was found that rate constants of the dimeric forms of the E-s-E-s-trans and E-s-Z-s-trans conformers are higher than those of the monomers and are independent on total enaminoketone concentration. Addition of highly polar HMPA promotes proton transfer from nitrogen to oxygen in the Z-s-Z-s-trans isomer of 2 with subsequent isomerization into the linear imino enol product but the rate constant of this transformation is ten-fold smaller than that for 1 in the Ar matrix exposed to UV radiation. PMID- 29579715 TI - Blue emitting copper nanoclusters as colorimetric and fluorescent probe for the selective detection of bilirubin. AB - Hurdles to develop point of care diagnostic methods restrict the translation of progress in the health care sector from bench side to bedside. In this article a simple, cost effective fluorescent as well as colorimetric nanosensor was developed for the early and easy detection of hyperbilirubinemia. A stable, water soluble bovine serum albumin stabilised copper nanocluster (BSA CuNC) was used as the fluorescent probe which exhibited strong blue emission (404nm) upon 330nm excitation. The fluorescence of the BSA CuNC can be effectively quenched by the addition of bilirubin by the formation of copper-bilirubin complex. Meanwhile the copper-bilirubin complex resulted in an observable colour change from pale violet to green facilitating colorimetric detection. The prepared sensor displayed good selectivity and sensitivity over other co-existing molecules, and can be used for quantifying bilirubin with a detection limit down to 257fM. Additionally, the as prepared probe was coated on a paper strip to develop a portable paper strip sensor of bilirubin. Moreover, the method was successfully applied in real sample analysis and obtained promising result. PMID- 29579717 TI - Pseudoprogression and hyperprogression after checkpoint blockade. AB - Immune checkpoint inhibitors appear to be one of the most promising immunotherapies with significant clinical benefits and durable responses in multiple tumor types. A heterogeneity of responses appears in patients receiving checkpoint blockade, including pseudoprogression where the tumor burden or number of tumor lesions increases initially before decreasing. Another special response observed after checkpoint blockade is hyperprogression, a phenomenon reflecting a very rapid tumor progression following immunotherapy, suggesting that checkpoint blockade could impact detrimentally on a small subset of patients. As immunotherapeutics, especially anti-PD-1/PD-L1 agents, become more widely available, evaluating the efficacy of these novel drugs poses a major challenge to clinicians, who aim to avoid either premature withdrawal of the treatment or prolonging ineffective treatment. Although the mechanism and recognition of pseudoprogression have gradually come to light, the incidence, basis, identification and predictive biomarkers of hyperprogression have been largely unknown, and this review documents the existing research findings and points out the areas where further studies are badly needed. PMID- 29579718 TI - Post-feeding activity of Lucilia sericata (Diptera: Calliphoridae) on common domestic indoor surfaces and its effect on development. AB - Developmental data of forensically important blowflies used by entomologists to estimate minimum post mortem interval (mPMI) are established under controlled laboratory conditions for various temperature ranges throughout the stages of egg, 1st-3rd instar, puparia, and adult fly emergence. However, environmental conditions may influence the patterns of development and behaviour of blowflies, potentially impacting on these established development rates. Previous studies investigating indoor colonisation have focused on the delay to oviposition, with behaviour during the post-feeding phase in this setting often overlooked. The environment in which third instar larvae disperse when searching for a pupariation site may vary drastically at both outdoor and indoor scenarios, influencing the activity and distance travelled during this phase and possibly affecting developmental rates. This study investigated the effect of eight common domestic indoor surfaces on dispersal time, distance travelled, and behaviour of post-feeding Lucilia sericata as well as any resulting variation in development. It was found that pupariation and puparia length within a pupariation medium of sawdust (often used in laboratory settings) produced comparable results with that of carpeted environments (those deemed to be 'enclosed'). Non-carpeted environments (those which were 'exposed') produced a delay to pupariation likely due to increased activity and energy expenditure in searching for pupariation sites which enabled burial. In addition, the observed speed of travel during dispersal was seen via time lapse photography to be greater within 'exposed' conditions. Larvae which dispersed upon burnt laminate flooring were observed to travel faster than in all other conditions and showed the only significant variation (P=0.04) in the day of emergence in comparison to the control condition of sawdust. This study has demonstrated that wandering phase activity is affected by the environmental surface which has potential implications for estimating both the distance travelled by dispersing larvae in indoor conditions and with further research, may be a consideration in mPMI calculations. PMID- 29579720 TI - Biomechanical analysis of the durability of a modified S1 vertebrae transpedicular screws insertion technique. AB - BACKGROUND: One of the most important elements of the transpedicular screw implantation technique, which enables a strong screw-bone interface, is the precise choice of the site of screw insertion and the screw's trajectory. Due to the complex biomechanics of the lumbosacral interface and different shape of the sacrum, fixation of this segment remains a challenge for surgeons. Because of this, Kubaszewski et al. proposed a modified technique in which the entry point for screw insertion in the S1 vertebra is changed. METHODS: Six human cadaver specimens of the S1 vertebrae were examined. Two transpedicular screws were inserted into the body of each examined vertebra using two implantation methods with different screw entry points and trajectories. The screws were subjected to cyclic preloading, followed by the pull-out test. The ultimate pull-out force, displacement, stiffness, and failure energy were measured. FINDINGS: The average pull-out force obtained for the standard method of implantation was 498 N (SD 201), whereas for the modified technique, it was 1308 N (SD 581). Displacement of the inserted screws in the new method was 36% higher than in the case of the standard method. This method is also characterized by the greater stiffness of the obtained interface and greater failure energy than the normally used technique. INTERPRETATION: The obtained results demonstrate that the use of the new technique of implantation significantly increases the strength of the obtained screw-bone interface. It should also increase the success rate of the performed fixations and increase the safety of such fixations in clinical practice. PMID- 29579721 TI - The influence of isolated femur and tibia rotations on patella cartilage stress: a sensitivity analysis. AB - BACKGROUND: To determine the influence of femur and tibia rotations in the transverse and frontal planes on patella cartilage stress. METHODS: Patella cartilage stress profiles of six healthy females were obtained during a squatting task using subject-specific finite element models of the patellofemoral joint (45 degrees of knee flexion). Input parameters for the finite element model included joint geometry, quadriceps muscle forces, and weight-bearing patellofemoral joint kinematics. The femur and tibia of each model were then rotated to 2 degrees , 4 degrees , 6 degrees , 8 degrees , and 10 degrees along their respective axes beyond that of the natural degree of rotation in weight-bearing. The process was repeated for internal rotation, external rotation, adduction, and abduction. Quasi-static loading simulations were performed to quantify average patella cartilage stress. FINDINGS: Incremental femur internal rotation beyond that of the natural rotation resulted in progressively greater patella cartilage stress (41-77%), whereas incremental tibia internal rotation resulted in a decrease in patella cartilage stress (7-10%). Femur and tibia external rotation resulted in a mild increase in patella cartilage stress, but only at 10 degrees (9%). Incremental femur adduction resulted in an increase in patella cartilage stress, but only at 10 degrees (43%). Femur abduction and frontal plane tibia rotation in either direction had no influence on patella cartilage stress. INTERPRETATION: Femur internal rotation and adduction resulted in the greatest increases in patella cartilage stress. In contrast, tibia rotations in the transverse and frontal planes had minimal to no influence on patella cartilage stress. These results emphasize the need for clinicians to identify and correct faulty hip kinematics in persons with PFP. PMID- 29579719 TI - Copper accumulation in senescent cells: Interplay between copper transporters and impaired autophagy. AB - Cellular senescence is characterized by irreversible growth arrest incurred through either replicative exhaustion or by pro-oncogenic cellular stressors (radioactivity, oxidative stress, oncogenic activation). The enrichment of senescent cells in tissues with age has been associated with tissue dyshomeostasis and age-related pathologies including cancers, neurodegenerative disorders (e.g. Alzheimer's, Parkinson's, etc.) and metabolic disorders (e.g. diabetes). We identified copper accumulation as being a universal feature of senescent cells [mouse embryonic fibroblasts (MEF), human prostate epithelial cells and human diploid fibroblasts] in vitro. Elevated copper in senescent MEFs was accompanied by elevated levels of high-affinity copper uptake protein 1 (Ctr1), diminished levels of copper-transporting ATPase 1 (Atp7a) (copper export) and enhanced antioxidant defence reflected by elevated levels of glutathione (GSH), superoxide dismutase 1 (SOD1) and glutaredoxin 1 (Grx1). The levels of intracellular copper were further increased in senescent MEFs cultured in copper supplemented medium and in senescent Mottled Brindled (Mobr) MEFs lacking functional Atp7a. Finally, we demonstrated that the restoration/preservation of autophagic-lysosomal degradation in senescent MEFs following rapamycin treatment correlated with attenuation of copper accumulation in these cells despite a further decrease in Atp7a levels. This study for the first time establishes a link between Atp7a and the autophagic-lysosomal pathway, and a requirement for both to effect efficient copper export. Such a connection between cellular autophagy and copper homeostasis is significant, as both have emerged as important facets of age-associated degenerative disease. PMID- 29579722 TI - Attachment insecurity and power regulation in intimate relationships. AB - Power and dependence are fundamental to the development of attachment insecurity and attachment insecurity is central in defining different ways people regulate power. This paper applies an integrated power and attachment perspective to advance understanding of the diverse ways people attempt to negotiate dependence and power in adult relationships. The paper demonstrates how: (1) power is integral to the concerns and goals underlying attachment avoidance and anxiety, (2) the situations that activate attachment strategies represent specific power relevant concerns and goals, (3) the reactions associated with avoidance and anxiety reflect distinct strategies to regulate dependence and control, and (4) partners counter with their own power regulation attempts. The integrative model presented generates new insights into both power and attachment dynamics. PMID- 29579723 TI - Attachment and eating disorders: a research update. AB - Prominent models of eating disorders tend to focus on cognitive and behavioral features, but tend not to consider important developmental issues related to affect regulation, interpersonal style, self concept, and mentalization-all of which are well conceptualized within attachment theory. Higher levels of attachment insecurity across diagnoses are related to greater eating disorder symptoms. Low parental care and early trauma may lead to attachment insecurity that then might lead to greater eating disorder symptoms. The association between insecure attachment and eating disorder severity is likely mediated by affect dysregulation and perfectionism. Recent research using the Adult Attachment Interview highlights the importance of reflective functioning in predicting treatment response and therapeutic processes, and on the utility of therapies that increase mentalization. PMID- 29579724 TI - Associations between opioid and nicotine dependence in nationally representative samples of United States adult daily smokers. AB - INTRODUCTION: Smoking prevalence among adults with opioid dependence far exceeds that of the general population, and cessation outcomes in this group are one fourth that of smokers without a substance use disorder. Understanding the reasons underlying these poor outcomes is critical for developing more effective smoking interventions in this group. Elevated baseline severity of nicotine dependence is associated with lower rates of smoking cessation over time. We examined whether nicotine dependence severity among smokers may vary as a function of opioid dependence status using nationally representative samples of adult smokers. METHODS: Data were derived from multiple years of the National Survey on Drug Use and Health (NSDUH, 2006-2014; n = 58,971). Nicotine dependence was measured by the Nicotine Dependence Syndrome Scale (NDSS) and the first item (i.e., time to first cigarette) of the Fagerstrom Test for Nicotine Dependence (FTND). Opioid dependence was assessed using the Diagnostic and Statistical Manual of Mental Disorders criteria. RESULTS: Opioid-dependent smokers exhibited greater severity of nicotine dependence compared to non-opioid dependent smokers, as evidenced by higher mean NDSS scores (p < 0.05). On both NDSS and FTND measures of nicotine dependence, opioid-dependent smokers were also approximately twice as likely to be dependent on nicotine than those not dependent on opioids (p's < 0.05). CONCLUSIONS: Opioid dependence is associated with increased severity and prevalence of nicotine dependence among smokers. Considering the disproportionate societal and economic burdens of smoking and smoking-related consequences in this vulnerable population, continued investigations are needed to better understand opioid-dependent individuals' poor cessation outcomes. PMID- 29579725 TI - Addressing discordant quantitative urine buprenorphine and norbuprenorphine levels: Case examples in opioid use disorder. AB - INTRODUCTION: Urine adulteration is a concern among patients treated for opioid use disorder. Quantitative urine testing for buprenorphine (B) and norbuprenorphine (NB), and the appropriate interpretation of B and NB levels, can facilitate constructive conversations with patients that may lead to modifications in the treatment plan, and strengthening of the patient-provider relationship. CASE SUMMARY: Three cases are presented in which discordant urine B and NB levels were recognized. Each patient was submerging buprenorphine/naloxone strips in their urine to mask ongoing illicit drug use. The authors used an approach to addressing intentional adulteration of urine samples that adheres to the principles of harm-reduction, the centrality of the patient-provider relationship, and the acknowledgment that ongoing illicit drug use and subsequent dishonesty about disclosure may be common among persons with substance use disorders. Each of the three patients ultimately endorsed diluting their urine, which allowed for strengthening of the patient-provider relationship and modifications to their treatment plans. Two of the three patients stabilized and achieved abstinence, while the third was eventually referred to a methadone treatment program. CONCLUSION: Providers should routinely monitor B and NB levels, rather than qualitative screening alone, and discordant levels should elicit a timely conversation with the patient. The authors use of a nonjudgmental approach to address urine adulteration, including giving patients an opportunity to reflect on potential solutions, has been effective at helping patients and providers to reestablish a therapeutic alliance and maintain retention in treatment. PMID- 29579726 TI - Significance, evolution and recent advances in adsorption technology, materials and processes for desalination, water softening and salt removal. AB - Desalination and softening of sea, brackish, and ground water are becoming increasingly important solutions to overcome water shortage challenges. Various technologies have been developed for salt removal from water resources including multi-stage flash, multi-effect distillation, ion exchange, reverse osmosis, nanofiltration, electrodialysis, as well as adsorption. Recently, removal of solutes by adsorption onto selective adsorbents has shown promising perspectives. Different types of adsorbents such as zeolites, carbon nanotubes (CNTs), activated carbons, graphenes, magnetic adsorbents, and low-cost adsorbents (natural materials, industrial by-products and wastes, bio-sorbents, and biopolymer) have been synthesized and examined for salt removal from aqueous solutions. It is obvious from literature that the existing adsorbents have good potentials for desalination and water softening. Besides, nano-adsorbents have desirable surface area and adsorption capacity, though are not found at economically viable prices and still have challenges in recovery and reuse. On the other hand, natural and modified adsorbents seem to be efficient alternatives for this application compared to other types of adsorbents due to their availability and low cost. Some novel adsorbents are also emerging. Generally, there are a few issues such as low selectivity and adsorption capacity, process efficiency, complexity in preparation or synthesis, and problems associated to recovery and reuse that require considerable improvements in research and process development. Moreover, large-scale applications of sorbents and their practical utility need to be evaluated for possible commercialization and scale up. PMID- 29579727 TI - Protected area effectiveness against land development in Spain. AB - Land use-land cover (LULC) changes towards artificial covers are one of the main global threats to biodiversity conservation. In this comprehensive study, we tested a number of methodological and research hypotheses, and a new covariate control technique in order to address common protected area (PA) assessment issues and accurately assess whether different PA networks have had an effect at preventing development of artificial LULCs in Spain, a highly biodiverse country that has experienced massive socioeconomic transformations in the past two decades. We used digital census data for four PA networks designated between 1990 and 2000: Nature Reserves (NRs), Nature Parks (NPs), Sites of Community Importance (SCIs) and Special Protection Areas (SPAs). We analysed the effect of explanatory variables on the ecological effectiveness of protected polygons (PPs): Legislation stringency, cummulative legal designations, management, size, age and bio-physical characteristics. A multiple Before-After-Control-Impact (BACI) semi-experimental research design was used whereby artificial land cover increase (ALCI) and proportional artificial land cover increase (PALCI) results were compared inside and outside PAs, using 1 km and 5 km buffer areas surrounding PAs as controls. LULC data were retrieved from Corine Land Cover (CLC) 1990 and 2006 data. Results from three spatial-statistical models using progressively restrictive criteria to select control areas increasingly more accurate and similar to the assessed PPs were compared. PAs were a generally effective territorial policy to prevent land development in Spain. NRs were the most effective PA category, with no new artificial land covers in the assessed period, although exact causality could not be attributed due to legal overlaps. SPAs were the least effective category, with worse ALCI data than their control areas. Legal protection was effective against land development, which was influenced by most bio-physical variables. However, cumulative legal designations and PA management did not seem to influence land development. The spatial statistical technique used to make cases and control environmentally similar did not produce consistent outcomes and should be refined. PMID- 29579728 TI - Wastewater post-treatment for simultaneous ammonium removal and elemental sulfur recovery using a novel horizontal mixed aerobic-anoxic fixed-bed reactor configuration. AB - A novel horizontal mixed anoxic-aerobic fixed-bed reactor configuration based on nitrification coupled with autotrophic denitrification using hydrogen sulfide as an electron donor was developed. The nitrification removal efficiency (RE) reached values greater than 99% but was slightly affected by the accumulation of dissolved sulfur species in the liquid phase. The denitrification RE reached 99% with a H2S inlet load of 28.6 g S m-3 h-1, although the use of aluminum polychloride (PAC) as a sulfur coagulant in the anoxic zone affected the buffering capacity of the system and resulted in a decrease in the RE. The performance of the reactor was primarily affected by the buffering capacity of the system, and this effect could be controlled with an increase in the NaHCO3 concentration. The recovery of biogenic elemental sulfur was possible using PAC as a coagulant, although the solid collected at the bottom of the settling tank contained only 1.5% S0. PMID- 29579729 TI - Antibacterial activity on superhydrophobic titania nanotube arrays. AB - Bacterial infections are a serious issue for many implanted medical devices. Infections occur when bacteria colonize the surface of an implant and form a biofilm, a barrier which protects the bacterial colony from antibiotic treatments. Further, the anti-bacterial treatments must also be tailored to the specific bacteria that is causing the infection. The inherent protection of bacteria in the biofilm, differences in bacteria species (gram-positive vs. gram negative), and the rise of antibiotic-resistant strains of bacteria makes device acquired infections difficult to treat. Recent research has focused on reducing biofilm formation on medical devices by modifying implant surfaces. Proposed methods have included antibacterial surface coatings, release of antibacterial drugs from surfaces, and materials which promote the adhesion of non-pathogenic bacteria. However, no approach has proven successful in repelling both gram positive and gram-negative bacteria. In this study, we have evaluated the ability of superhydrophobic surfaces to reduce bacteria adhesion regardless of whether the bacteria are gram-positive or gram-negative. Although superhydrophobic surfaces did not repel bacteria completely, they had minimal bacteria attached after 24 h and more importantly no biofilm formation was observed.

PMID- 29579731 TI - Conceptualizing plant systems evolution. AB - Organisms inhabiting extreme environments are emerging models in systems evolution, enabling us to identify the molecular alterations effecting major phenotypic divergence through comparative approaches. Here I discuss possible physiological mechanisms underlying evolutionary adaptations to extreme environments both theoretically and in relation to experimental observations. Reasoning leads me to the 'conserved steady-state' hypothesis of evolutionary adaptation: Between closely related plants adapted to differently composed soils, the homeostatically controlled steady-state set point cytosolic (buffered) concentrations of mineral ions are conserved. Subsequently, I compare molecular alterations expected to contribute to physiological adaptations with our present knowledge. Key roles of enhanced gene product dosage in plant evolutionary adaptations question the widespread stimulus response-centric paradigm. As a broader implication, co-regulation networks can lack decisive functional network elements. With this article, I hope to stimulate a discussion across research fields and provide an initial conceptual framework for future experimental testing and for quantitative modelling. PMID- 29579732 TI - Development, validation and utilization of a highly sensitive LC-MS/MS method for quantification of levonorgestrel released from a subdermal implant in human plasma. AB - Levonorgestrel (LNG) is a synthetic progestin that is available in oral contraceptive tablets, a subdermal implant, and an intrauterine system for contraception. LNG pharmacokinetics are a pivotal determinant of contraceptive efficacy and essential in assessing drug-drug interactions influencing LNG exposure following different routes of LNG administration. A highly sensitive LC MS/MS method was developed and validated to quantify levonorgestrel in human plasma. Liquid-liquid extraction was utilized with a sample volume of 500 MUL to extract levonorgestrel from plasma. Chromatographic separation of LNG was achieved with a FortisTM C18 (3 MUm: 100 mm * 2.1 mm) reverse phase analytical column. The mobile phases consisted of de-ionized water plus 0.1% NH4OH (100:0.1%, v/v) (A), and methanol plus 0.1% NH4OH (100:0.1%, v/v) (B) delivered as a gradient at a flow rate of 400 MUL/min. Detection of LNG and internal standard (D-(-)-norgestrel-d7) was achieved using positive polarity mode monitoring at 313.2-245.2 amu and 320.1-251.2 amu, respectively. The assay was linear over the calibration range of 49.6 to 1500 pg/mL. This method was used to quantify plasma LNG released by subdermal implant in support of a drug interaction study among women with HIV receiving efavirenz- or nevirapine-based antiretroviral therapy. PMID- 29579733 TI - Optimization of a two-dimensional liquid chromatography-supercritical fluid chromatography-mass spectrometry (2D-LC-SFS-MS) system to assess "in-vivo" inter conversion of chiral drug molecules. AB - Enantioselective analysis is an essential requirement during the pharmaceutical development of chiral drug molecules. In pre-clinical and clinical studies, the Food and Drug Administration (FDA) mandates the assessment of "in vivo" inter conversion of chiral drugs to determine their physiological effects. In-vivo analysis of the active pharmaceutical ingredient (API) and its potential metabolites could be quite challenging due to their low abundance (ng/mL levels) and matrix interferences. Therefore, highly selective and sensitive analytical techniques are required to separate the API and its metabolites from the matrix components and one another. Additionally, for chiral APIs, further analytical separation is required to resolve the API and its potential metabolites from their corresponding enantiomers. In this work, we demonstrate the optimization of our previously designed two-dimensional liquid chromatography-supercritical fluid chromatography-mass spectrometry (2D-LC-SFC -MS) system to achieve 10 ng/mL detection limit [1]. The first LC dimension, used as a desalting step, could efficiently separate the API from its potential metabolites and matrix components. The API and its metabolites were then trapped/focused on small trapping columns and transferred onto the second SFC dimension for chiral separation. Detection can be achieved by ultra-violet (UV) or MS detection. Different system parameters such as column dimensions, transfer volumes, trapping column stationary phase, system tubing internal diameter (i.d.), and detection techniques, were optimized to enhance the sensitivity of the 2D-LC-SFC-MS system. The limit of detection was determined to be 10 ng/mL. An application is described where a mouse hepatocyte treated sample was analyzed using the optimized 2D-LC SFC-MS system with successful assessment of the ratio of API to its metabolite (1D-LC), as well as the corresponding enantiomeric excess values (% e.e.) of each (2D-SFC). PMID- 29579734 TI - Major signal suppression from metal ion clusters in SFC/ESI-MS - Cause and effects. AB - The widening application area of SFC-MS with polar analytes and water-containing samples facilitates the use of quick and simple sample preparation techniques such as "dilute and shoot" and protein precipitation. This has also introduced new polar interfering components such as alkali metal ions naturally abundant in e.g. blood plasma and urine, which have shown to be retained using screening conditions in SFC/ESI-TOF-MS and causing areas of major ion suppression. Analytes co-eluting with these clusters will have a decreased signal intensity, which might have a major effect on both quantification and identification. When investigating the composition of the alkali metal clusters using accurate mass and isotopic pattern, it could be concluded that they were previously not described in the literature. Using NaCl and KCl standards and different chromatographic conditions, varying e.g. column and modifier, the clusters proved to be formed from the alkali metal ions in combination with the alcohol modifier and make-up solvent. Their compositions were [(XOCH3)n + X]+, [(XOH)n + X]+, [(X2CO3)n + X]+ and [(XOOCOCH3)n + X]+ for X = Na+ or K+ in ESI+. In ESI-, the clusters depended more on modifier, with [(XCl)n + Cl]- and [(XOCH3)n + OCH3]- mainly formed in pure methanol and [(XOOCH)n + OOCH]- when 20 mM NH4Fa was added. To prevent the formation of the clusters by avoiding methanol as modifier might be difficult, as this is a widely used modifier providing good solubility when analyzing polar compounds in SFC. A sample preparation with e.g. LLE would remove the alkali ions, however also introducing a time consuming and discriminating step into the method. Since the alkali metal ions were retained and affected by chromatographic adjustments as e.g. mobile phase modifications, a way to avoid them could therefore be chromatographic tuning, when analyzing samples containing them.

AB - Proanthocyanidins have been characterized in the different organs of Geranium sylvaticum by using an off-line 2-dimensional chromatographic method. In the first dimension, proanthocyanidins were separated according to their increasing degree of polymerization by hydrophilic interaction liquid chromatography. In the second dimension, reversed-phase liquid chromatography was used to separate the same size isomers based on their hydrophobicity. Ultraviolet detection and high resolution electrospray ionization time-of-flight mass spectrometry were used for the identification and characterization of proanthocyanidins. The method was proven to be suitable for the analysis of plant organ fractions of G. sylvaticum that contained complex mixtures of phenolic compounds and proanthocyanidins from several classes. Procyanidins, prodelphinidins and mixed proanthocyanidins composed of both (epi)catechin and (epi)gallocatechin units including monomers, oligomers and polymers up to the degree of polymerization of 20 were identified. The type and size of proanthocyanidins varied between eight studied organs of G. sylvaticum. The 2-dimensional analysis revealed that each proanthocyanidin type occur in the equally complex isomeric pattern. The mean degree of polymerization of different proanthocyanidins in the eight plant organs of G. sylvaticum was 5 and it varied only slightly between plant organs. PMID- 29579737 TI - A Facets Analysis of Analytic vs. Holistic Scoring of Identical Short Constructed Response Items: Different Outcomes and Their Implications for Scoring Rubric Development. AB - In scoring short constructed-response items it may be possible to apply different rubric types depending on the trait of achievement assessed. A rating scale and a partial credit Many-Facet Rasch Models (MFRM) were used to investigate whether levels-based (holistic) and hybrid (analytic) scoring rubrics functioned interchangeably when scoring short-response English reading comprehension test items. Whereas most research in similar contexts has focused solely on rater reliability, the use of MFRM in this study enabled examination of both the reliability and rating scale functioning aspects of scoring rubrics in parallel. It also enabled consideration of their effects on item and examinee parameters. This more comprehensive approach allowed the findings to be linked to general notions of rubric construct-relevance and score interpretation, and to demonstrate an approach to generating evidence for a more balanced consideration of advantages and disadvantages of each rubric in terms of both reliability and validity. PMID- 29579736 TI - Metformin reduces glucose intolerance caused by rapamycin treatment in genetically heterogeneous female mice. AB - The use of rapamycin to extend lifespan and delay age-related disease in mice is well-established despite its potential to impair glucose metabolism which is driven partially due to increased hepatic gluconeogenesis. We tested whether a combination therapeutic approach using rapamycin and metformin could diminish some of the known metabolic defects caused by rapamycin treatment in mice. In genetically heterogeneous HET3 mice, we found that chronic administration of encapsulated rapamycin by diet caused a measurable defect in glucose metabolism in both male and female mice as early as 1 month after treatment. In female mice, this defect was alleviated over time by simultaneous treatment with metformin, also by diet, such that females treated with both drugs where indistinguishable from control mice during glucose tolerance tests. While rapamycin-mediated glucose intolerance was unaffected by metformin in males, we found metformin prevented rapamycin-mediated reduction in insulin and leptin concentrations following 9 months of co-treatment. Recently, the Interventions Testing Program showed that mice treated with metformin and rapamycin live at least as long as those treated with rapamycin alone. Together, our data provide compelling evidence that the pro-longevity effects of rapamycin can be uncoupled from its detrimental effects on metabolism through combined therapeutic approaches. PMID- 29579738 TI - Q-Matrix Optimization Based on the Linear Logistic Test Model. AB - This study explored optimization of item-attribute matrices with the linear logistic test model (Fischer, 1973), with optimal models explaining more variance in item difficulty due to identified item attributes. Data were 8th-grade mathematics test item responses of two TIMSS 2007 booklets. The study investigated three categories of attributes (content, cognitive process, and comprehensive cognitive process) at two grain levels (larger, smaller) and also compared results with random attribute matrices. The proposed attributes accounted for most of the variance in item difficulty for two assessment booklets (81% and 65%). The variance explained by the content attributes was very small (13% to 31%), less than variance explained by the comprehensive cognitive process attributes which explained much more variance than the content and cognitive process attributes. The variances explained by the grain level were similar to each other. However, the attributes did not predict the item difficulties of two assessment booklets equally. PMID- 29579739 TI - Mapping a Data Modeling and Statistical Reasoning Learning Progression using Unidimensional and Multidimensional Item Response Models. AB - There are different ways to conceive and measure learning progressions. The approach used by the ADMSR project followed the "four building blocks" approach outlined by the Berkeley Evaluation and Assessment Research (BEAR) Center and the BEAR Assessment System. The final building block of this approach involves the application of a measurement model. This paper focuses on the application of unidimensional and multidimensional item response theory (IRT) measurement models to the data from the ADMSR project. Unidimensional IRT models are applied to aid in construct development and validation to see if the proposed theory of development presented by the construct map is supported by the results from an administration of the instrument. Multidimensional IRT measurement models are applied to examine the relationships between the seven constructs in the ADMSR learning progression. When applying the multidimensional model, specific links between levels of the constructs are analyzed across constructs after the application of a technique to align the seven dimensions. PMID- 29579740 TI - Psychometric Properties of the Classroom Assessment Scoring System (Pre-K): Implications for Measuring Interaction Quality in Diverse Early Childhood Settings. AB - The Classroom Assessment Scoring System (CLASS) is an observational instrument assessing the nature of everyday interactions in educational settings. The instrument has strong theoretical groundings; however, prior empirical validation of the CLASS has exposed some psychometric weaknesses. Further the instrument has not been the subject of psychometric analysis at the indicator level. Using a large dataset including observations of 993 Australian classrooms, confirmatory factor analysis is used to replicate findings from the few existing validation studies. Item response modelling is used to examine individual indicator behaviour. Latent growth models are used to produce new findings about estimating factor scores. Findings show that the CLASS exhibits stable psychometric properties within classrooms over repeated observations. Model fit is improved and factor scores are more reliable when the repeated-observations made in administering the CLASS are accounted for statistically. It is recommended that researchers enforce a fixed number of repeated observations to minimise bias. PMID- 29579741 TI - Ordered Partition Model for Confidence Marking Modeling. AB - Confidence marking is increasingly used in multiple choice testing situations, but when the Rasch measurement model is applied to the data, only the binary data is used, discarding the information given by the confidence marking. This study shows how Wilson's ordered partition model (OPM), a member of the Rasch family of models, can be used to model the confidence information. The result is a model which is in strict relation to the binary Rasch model, since the Rasch ICC's are "split" into a set of curves each representing a confidence level. The new model provides a set of item parameters that map the probability of being in each confidence level in relation to the test-taker's ability. The study provides a powerful diagnostic tool to assess item difficulty, overconfidence or misuse of confidence levels but also the fact that a question is particularly tricky or creates a lot of doubt. PMID- 29579742 TI - Development of an Item Bank for the Assessment of Knowledge on Biology in Argentine University Students. AB - The calibration of item banks provides the basis for computerized adaptive testing that ensures high diagnostic precision and minimizes participants' test burden. This study aims to develop a bank of items to measure the level of Knowledge on Biology using the Rasch model. The sample consisted of 1219 participants that studied in different faculties of the National University of Cordoba (mean age = 21.85 years, SD = 4.66; 66.9% are women). The items were organized in different forms and into separate subtests, with some common items across subtests. The students were told they had to answer 60 questions of knowledge on biology. Evaluation of Rasch model fit (Zstd >|2.0|), differential item functioning, dimensionality, local independence, item and person separation (>2.0), and reliability (>.80) resulted in a bank of 180 items with good psychometric properties. The bank provides items with a wide range of content coverage and may serve as a sound basis for computerized adaptive testing applications. The contribution of this work is significant in the field of educational assessment in Argentina. PMID- 29579743 TI - Room-temperature nine-um-wavelength photodetectors and GHz-frequency heterodyne receivers. AB - Room-temperature operation is essential for any optoelectronics technology that aims to provide low-cost, compact systems for widespread applications. A recent technological advance in this direction is bolometric detection for thermal imaging, which has achieved relatively high sensitivity and video rates (about 60 hertz) at room temperature. However, owing to thermally induced dark current, room-temperature operation is still a great challenge for semiconductor photodetectors targeting the wavelength band between 8 and 12 micrometres, and all relevant applications, such as imaging, environmental remote sensing and laser-based free-space communication, have been realized at low temperatures. For these devices, high sensitivity and high speed have never been compatible with high-temperature operation. Here we show that a long-wavelength (nine micrometres) infrared quantum-well photodetector fabricated from a metamaterial made of sub-wavelength metallic resonators exhibits strongly enhanced performance with respect to the state of the art up to room temperature. This occurs because the photonic collection area of each resonator is much larger than its electrical area, thus substantially reducing the dark current of the device. Furthermore, we show that our photonic architecture overcomes intrinsic limitations of the material, such as the drop of the electronic drift velocity with temperature, which constrains conventional geometries at cryogenic operation. Finally, the reduced physical area of the device and its increased responsivity allow us to take advantage of the intrinsic high-frequency response of the quantum detector at room temperature. By mixing the frequencies of two quantum-cascade lasers on the detector, which acts as a heterodyne receiver, we have measured a high frequency signal, above four gigahertz (GHz). Therefore, these wide-band uncooled detectors could benefit technologies such as high-speed (gigabits per second) multichannel coherent data transfer and high-precision molecular spectroscopy. PMID- 29579744 TI - Antimicrobial Essential Oil Combinations to Combat Foot Odour. AB - Foot odour (bromodosis) is an embarrassing and perplexing condition mostly caused by bacteria of the Brevibacterium species. Essential oils are a credible option as an affordable treatment of odour and contribute towards antimicrobial efficacy. Therefore, this study sets out to investigate the antimicrobial activity of essential oil combinations against odour-causing bacteria. The broth microdilution method was used to investigate the antimicrobial activity of 119 essential oil combinations, and the fractional inhibitory index was calculated to determine the interactive profile. Combinations that resulted in synergy in 1 : 1 ratios were further evaluated in different concentrations, and isobolograms were plotted to determine the influence of the ratio on overall activity. Numerous combinations could be identified as having synergistic interactions against the Brevibacterium spp. and no antagonism was observed. The combination of Juniperus virginiana (juniper) and Styrax benzoin (benzoin) demonstrated synergy against all three Brevibacterium spp. tested and J. virginiana was the essential oil responsible for the majority of the synergistic interactions. The results reported here confirm the promising potential of the majority of these oils and selected combinations in treating and controlling bromodosis. PMID- 29579745 TI - Free-Flap Lower Extremity Reconstruction: A Cohort Study and Meta-Analysis of Flap Anastomotic Outcomes between Perforator and Nonperforator Flaps. AB - INTRODUCTION: Free-flap outcomes in lower extremity reconstruction carry the lowest anastomotic success rates compared with other anatomical sites. Despite their advantages over traditional nonperforator flaps, free perforator flaps have only recently become established in this area due to the additional challenges faced. It is therefore crucial to assess the anastomotic outcomes of perforator and nonperforator free flaps. METHODS: We performed a single-center retrospective cohort study and combined this with a meta-analysis of the relevant literature. We evaluated three flap anastomotic outcomes: reexploration, operative salvage, and flap failure rates. RESULTS: Between January 2010 and June 2015, our center managed 161 patients who underwent lower extremity free flap reconstruction, which included 76 perforator flaps and 85 nonperforator flaps. The perforator flaps had higher reexploration rates compared with the nonperforator flaps, but this was not statistically significant (18.4 and 10.6%; p = 0.18). Perforator flaps had a higher flap salvage rate but were not statistically significant (78.6 and 22.2%; p = 0.374). Lastly, although not statistically significant, perforator flaps had a lower rate of complete failure due to anastomotic complications (3.9 and 8.2%; p = 0.336). The meta-analysis included 12 studies (inclusive of the index study) and found no statistical difference in all three outcomes. CONCLUSION: Our meta-analysis is the first reported study and serves as an indication that free perforator flaps in lower extremity are as reliable as their traditional nonperforator counterparts. This does come with the prerequisite appreciation of the anatomical variations, the delicate handling of these flaps, and a low threshold for reexploration. PMID- 29579746 TI - Good Agreement Between Transabdominal and Endoscopic Ultrasound of the Pancreas in Chronic Pancreatitis. AB - PURPOSE: We aimed to evaluate the agreement of single criteria and dedicated scores from transabdominal ultrasound of the pancreas (US) compared to standards by endoscopic ultrasound (EUS) and computed tomography (CT). MATERIALS AND METHODS: In this observational cohort study performed in a tertiary care center, US and EUS were performed in 110 patients referred for suspected CP. Based on the Mayo score, 52 patients were diagnosed with CP. The sonographic findings obtained by both methods were registered. The number of criteria was counted and scored according to the Rosemont score. RESULTS: Agreement between the number of detected US and EUS criteria was substantial (ICC = 0.74 [0.61 - 0.83]. Adding Rosemont weighting improved the agreement (ICC = 0.88 [0.81 - 0.92]). Regarding individual criteria, the agreement was substantial for the detection of calcifications (kappa = 0.86) and moderate for cysts and irregular or dilated pancreatic duct (kappa = 0.42 - 0.58). Agreement for the other criteria was poorer (kappa<= 0.40). The diagnostic performance indices [95 % CI] of US for diagnosing CP (using Mayo score as reference standard) were for the unweighted score: Sensitivity: 0.65 [0.51 - 0.78], specificity: 0.97 [0.87 - 1.00]; and for Rosemont score: Sensitivity: 0.75 [0.61 - 0.86], specificity: 0.95 [0.83 - 0.99]. CONCLUSION: The agreement between US and EUS for the unweighted and weighted scores was substantial. For the features calcifications, cysts and main pancreatic duct (MPD) changes, agreement was moderate to substantial. For the other detected US criteria, the agreement with EUS was too poor to be clinically relevant. PMID- 29579747 TI - [Posterior Impingement Syndrome of the Ankle Joint]. PMID- 29579748 TI - ?

AB - BACKGROUND: Although supplemental oxygen (SO2) is routinely administered to laboring gravidas, benefits and harms are not well studied. OBJECTIVE: This article compares strategies of liberal versus indicated SO2 therapy during labor on cesarean delivery (CD) rate and neonatal outcomes. STUDY DESIGN: A controlled, before-and-after trial of laboring women with term, singleton pregnancies. During an initial 8-week period, maternal SO2 was administered at the discretion of the provider followed by an 8-week period where SO2 was to be given only for protocol indications. RESULTS: Our study included 844 women. There was no difference in number of women receiving SO2 (53% liberal vs. 50% indicated; p = 0.33). For those receiving SO2, there was no difference in SO2 duration (median, 89 minutes [interquartile range, 42-172] vs. 87 minutes [36 152]; p = 0.42). There were no differences in overall CD rate (20% vs. 17%; p = 0.70), CD for nonreassuring fetal status, or use of intrauterine resuscitative measures. There were more 5-minute APGAR < 7 in the indicated group, but no difference in umbilical artery pH < 7.1 or neonatal intensive care unit (NICU) admission. CONCLUSION: Approximately half of women receive SO2 intrapartum regardless of a strategy of liberal or indicated oxygen use. There were no clinically significant differences in outcomes between strategies. PMID- 29579758 TI - Glucose Gel in Infants at Risk for Transitional Neonatal Hypoglycemia. AB - OBJECTIVE: To evaluate whether glucose gel as a supplement to feedings in infants admitted to the newborn nursery at risk for neonatal hypoglycemia (NH) reduces the frequency of transfer to a higher level of care for intravenous dextrose treatment. STUDY DESIGN: We revised our newborn nursery protocol for management of infants at risk for NH to include use of 40% glucose gel (200 mg/kg). Study population included late preterm, small and large for gestational age infants, and infants of diabetic mothers. We compared outcomes before (4/1/14 3/31/15: Year 1) and after (4/1/15-3/31/16: Year 2) initiation of the revised protocol. Our prospective primary outcome was transfer to the neonatal intensive care unit (NICU) for treatment with a continuous infusion of dextrose. RESULTS: NICU transfer for management of NH fell from 8.1% in Year 1 (34 of 421 at-risk infants screened) to 3.7% in Year 2 (14 of 383 at-risk infants screened). Rate of exclusive breastfeeding increased from 6% in Year 1 to 19% in Year 2. Hospital charges for the study population decreased from 801,276 USD to 387,688 USD in Year 1 and Year 2, respectively. CONCLUSION: Our study supports the adjunctive use of glucose gel to reduce NICU admissions and total hospitalization expense. PMID- 29579759 TI - Risk Factors for Neonatal Hypoxic-Ischemic Encephalopathy in the Absence of Sentinel Events. AB - OBJECTIVE: Hypoxic-ischemic encephalopathy (HIE) may be associated with intrapartum sentinel events or may be unexplained. We sought to identify risk factors for unexplained HIE cases and compare their morbidity and mortality to cases associated with sentinel events. STUDY DESIGN: Retrospective cohort study of all neonates admitted with suspected HIE treated with whole-body hypothermia from January 2007 through July 2017. Cases of unexplained HIE were compared with those with a sentinel event. RESULTS: A total of 223 neonates met the inclusion criteria, of which 86 (38.6%) experienced a sentinel event and 137 (61.4%) did not. Placental histopathology was performed for 28/31 (90.3%) and 48/53 (90.6%) inborn neonates with and without sentinel events, respectively. Placentas from unexplained HIE cases more often exhibited histologic chorioamnionitis (43.8% vs. 17.9%, p = 0.02) and funisitis (25% vs. 3.6%, p = 0.02). Neonatal morbidity and mortality were similar. On multivariable regression, nulliparity (odds ratio [OR], 4.11, 95% confidence interval [CI]: 1.24-13.62) and histologic funisitis (OR, 20.33, 95% CI: 1.11-373.4) remained significant. CONCLUSION: Other than nulliparity and infection which could be identified on umbilical cord examination following delivery but not on clinical assessment prior to delivery, there are no other identifiable risk factors for HIE in the absence of a sentinel event, and morbidity and mortality are similar between groups. PMID- 29579760 TI - Genetics of Lithium Response in Bipolar Disorder. AB - INTRODUCTION: Lithium remains the best-established long-term treatment for bipolar disorder because of its efficacy in maintaining periods of remission and reducing the risk of suicide. Not all patients successfully respond to lithium treatment, and the individual response, including the occurrence of side effects, is highly variable and not easy to predict. The genetic basis of lithium response is supported by the fact that the response clusters in families. Likewise, recent high-throughput genomic analyses have shed light on its genetic architecture. METHODS: This nonsystematic review summarizes the main results obtained in genetic association studies using lithium response as target trait. RESULTS: These studies suggest that several genetic loci might modulate the way a patient responds to lithium maintenance treatment. Further studies to fully characterize the genetic architecture of lithium response are warranted. DISCUSSION: The identification of genetic factors associated with lithium response will be important for (1) better understanding of lithium's mode of action and (2) development of a predictive model for optimization of long-term treatment of bipolar disorder. PMID- 29579761 TI - Surgical Site Infection in a Tertiary Neonatal Surgery Centre. AB - INTRODUCTION: Surgical site infection (SSI) is a key performance indicator to assess the quality of surgical care. Incidence and risk factors for SSI in neonatal surgery are lacking in the literature. AIM: To define the incidence of SSI and possible risk factors in a tertiary neonatal surgery centre. MATERIALS AND METHODS: This is a prospective cohort study of all the neonates who underwent abdominal and thoracic surgery between March 2012 and October 2016. The variables analyzed were gender, gestational age, birth weight, age at surgery, preoperative stay in neonatal intensive care unit, type of surgery, length of stay, and microorganisms isolated from the wounds. Statistical analysis was done with chi-square, Student's t- or Mann-Whitney U-tests. A logistic regression model was used to evaluate determinants of risk for SSI; variables were analyzed both with univariate and multivariate models. For the length of hospital stay, a logistic regression model was performed with independent variables. RESULTS: A total of 244 neonates underwent 319 surgical procedures. The overall incidence of SSIs was 43/319 (13.5%). The only statistical differences between neonates with and without SSI were preoperative stay (<4 days vs. >=4 days, p < 0.01) and length of hospital stay (<30 days vs. >=30 days, p < 0.01). A pre-operative stay longer than 4 days was associated with almost three times increased risk of SSI (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.05-8.34, p = 0.0407). Gastrointestinal procedures were associated with more than ten times the risk of SSI compared with other procedures (OR 10.17, 95% CI 3.82-27.10, p < 0.0001). Gastroschisis closure and necrotizing enterocolitis (NEC) laparotomies had the highest incidence SSI (54% and 62%, respectively). The risk of longer length of hospital stay after SSI was more than three times higher (OR = 3.36, 95%CI 1.63 6.94, p = 0.001). CONCLUSION: This is the first article benchmarking the incidence of SSI in neonatal surgery in the United Kingdom. A preoperative stay >=4 days and gastrointestinal procedures were independent risk factors for SSI. More research is needed to develop strategies to reduce SSI in selected neonatal procedures. PMID- 29579762 TI - Strategies in Development and Delivery of Nanotechnology Based Cosmetic Products. AB - The science of formulation involving cosmetic ingredients has always been a challenge since the release of active components greatly depends upon the carrier system involved and the selectivity of skin barrier. The principle obstacle of the skin resides in the epidermis and it's hard for many active components to cross it. The formulation related factors like size of particles, viscosity and lipophilicity of the components also play an important role in permeation of the dermal composition. Though widely used; conventional creams and gels still struggle in terms of success. This work focuses on nano based formulation strategies for successful delivery of cosmetic agents. Novel strategies like nanoemulsion, nanogels, liposomes, aquasomes, niosomes, dendrimers and fullerenes have paved way for successful delivery of dermal formulations to desire depths in the skin.

AB - INTRODUCTION: Previous findings from a pragmatic trial suggest that usual care compared with usual care plus individualised homeopathy is not a feasible design to address homeopathic interventions for asthma. OBJECTIVE: The main purpose of this article was to investigate the feasibility of the randomised withdrawal design as a strategy to assess the effectiveness of a standardised clinical pharmaceutical homeopathic protocol (Organon.modus) on perennial asthma in adolescents. METHODS: Randomised withdrawal, double-blind, parallel, placebo controlled, 12-week study. PATIENTS: 12 to 17 years old adolescents, with the diagnosis of perennial asthma, using inhalatory beclomethasone (plus fenoterol for wheezing episodes), who achieved 3 months of well-controlled asthma, after a variable period of individualised homeopathic treatment according to Organon.modus protocol. SETTING: a secondary care medical specialist centre. INTERVENTION: continuation with the individualised homeopathic medicine or with indistinguishable placebo during 12 weeks of beclomethasone step-down. PRIMARY OUTCOME: number of days of well-controlled asthma. Secondary measures: number of days of fenoterol use, number of visits to an emergency service (without hospitalisation) and percentage of patients excluded due to an exacerbation characterising a partly controlled asthma. Tolerability was assessed by Adverse Events, registered at every visit. RESULTS: Nineteen patients were randomised to continue treatment with homeopathy and 21 with placebo. Effectiveness measures for the homeopathy and placebo groups respectively were median number of days of good clinical control: 84 versus 30 (p = 0.18); median number of days of fenoterol use per patient: 3 versus 5 (p = 0.41); visits to an emergency room: 1 versus 6 (p = 0.35); percentage of exclusion due to partly controlled asthma: 36.8% versus 71.4% (p = 0.05). Few Adverse Events were reported. CONCLUSIONS: This pilot study supports the feasibility of the double-blind randomised withdrawal design in studies investigating homeopathy on teenage asthma, when performed by specialists following a standardised clinical-pharmaceutical homeopathic protocol.

PMID- 29579765 TI - Selection of Candidates for Lung Transplantation and Controversial Issues. AB - Lung transplantation is a widely accepted treatment to manage the advanced stages of many lung diseases that have failed to respond to all other therapeutic interventions. There have been ever-expanding indications for lung transplantation as a treatment for lung disease. The International Society for Heart and Lung Transplantation (ISHLT) updated guidelines for candidate selection in 2014. This document was published to serve as a guide in selecting appropriate candidates for lung transplantation. Ideal candidates for lung transplantation are those with near-end stage disease, limited life expectancy due to their lung disease, and who experience significant loss in quality of life. At the same time, candidates should be free of significant comorbidities that might negatively impact successful transplantation. Despite well thought out published guidelines for candidate selection, many controversial issues surrounding selection of lung transplant candidates remain. This review will focus on some of the more common controversial issues and explain how most centers approach these issues when choosing candidates for lung transplantation. PMID- 29579766 TI - How Should Lungs Be Allocated for Transplant? AB - As lung transplantation became established therapy for end-stage lung disease, there were not nearly enough suitable lungs from brain-dead organ donors to meet the need, leading to a focus on how lungs are allocated for transplant. Originally lungs were allocated by the United Network for Organ Sharing (UNOS) like hearts-by waiting time, first to listed recipients in the organ procurement organization of the donor, then to potential recipients in concentric 500 nautical mile circles. This resulted in long waiting times and increasing waitlist deaths. In 1999, the Health Resources and Services Administration published a Final Rule, requesting UNOS to review organ allocation algorithms to ensure that they complied with the desire to allocate organs based on urgency, avoiding futile transplants, and minimizing the role of waiting time in organ allocation. This led to development of the lung allocation score (LAS), which allocates lungs based on urgency and transplant benefit, introduced in 2005. The U.S. LAS system was adopted by Eurotransplant to allocate unused lungs between donor countries, and by both Germany and the Netherlands for lung allocation in their countries. This article will review the history of lung allocation, discuss the impact of LAS and its shortcomings, suggest recommendations to increase the number of lungs for transplant, and improve allocation of donated lungs. Ultimately, the goal of organ transplant research is to have so many organs to transplant that allocation systems are unnecessary. PMID- 29579767 TI - Donation after Brain Death versus Donation after Circulatory Death: Lung Donor Management Issues. AB - Lung transplantation (LTx) has traditionally been limited by a lack of suitable donor lungs. With the recognition that lungs are more robust than initially thought, the size of the donor pool of available lungs has increased dramatically in the past decade. Donation after brain death (DBD) and donation after circulatory death (DCD) lungs, both ideal and extended are now routinely utilized. DBD lungs can be damaged. There are important differences in the public's understanding, legal and consent processes, intensive care unit strategies, lung pathophysiology, logistics, and potential-to-actual donor conversion rates between DBD and DCD. Notwithstanding, the short- and long-term outcomes of LTx from any of these DBD versus DCD donor scenarios are now similar, robust, and continue to improve. Large audits suggest there remains a large untapped pool of DCD (but not DBD) lungs that may yet further dramatically increase lung transplant numbers. Donor scoring systems that might predict the donor conversion rates and lung quality, the role of ex vivo lung perfusion as an assessment and lung resuscitation tool, as well as the potential of donor lung quality biomarkers all have immense promise for the clinical field. PMID- 29579768 TI - Chronic Lung Allograft Dysfunction: Evolving Concepts and Therapies. AB - Lung transplantation has become an established therapeutic option for a variety of end-stage lung diseases. Technical advances in graft procurement, implantation, perioperative care, immunosuppression, and posttransplant medical management have led to significant improvements in 1-year survival, but outcomes after the first year have improved minimally over the last two decades. The main limitation to better long-term survival after lung transplantation is chronic lung allograft dysfunction (CLAD). CLAD also impairs quality of life and increases the costs of medical care. Our understanding of CLAD manifestations, risk factors, and mechanisms is rapidly evolving. Recognition of different CLAD phenotypes (e.g., bronchiolitis obliterans syndrome and restrictive allograft syndrome) and the unique pathogenic mechanisms will be important for developing novel therapies. In addition to alloimmune-mediated rejection, we now recognize the importance of alloimmune-independent mechanisms of injury to the allograft. CLAD is the consequence of dysregulated repair of allograft injury. Unfortunately, currently available therapies for CLAD are usually not effective. However, the advances in knowledge, reviewed in this manuscript, should lead to novel strategies for CLAD prevention and treatment, as well as improvement in long-term outcomes after lung transplantation. We provide an overview of the evolving terminology related to CLAD, its varying clinical phenotypes and their diagnosis, natural history, pathogenesis, and potential treatments. PMID- 29579769 TI - Immunosuppression: Have We Learnt Anything? AB - Outcomes after lung transplantation remain disappointing because there is a high incidence of chronic lung allograft dysfunction (CLAD), which typically follows a progressive clinical course and often results in allograft failure and death. Chronic rejection is considered the predominant cause of CLAD. Thus, optimal immunosuppression has been viewed as having the potential to prevent CLAD and improve survival after lung transplantation. Numerous clinical trials have been conducted investigating the efficacy and safety of various immunosuppressive agents. Many studies have been small and single-center clinical trials but some have been international and multicenter trials enrolling more than 300 patients. This review focuses on clinical trials of immunosuppression conducted in lung transplantation and points out strengths and limitations of the various studies. Ultimately, the findings of these clinical trials explain the current state of practice in lung transplantation and identify gaps in knowledge that require additional study. Finally, there is an ongoing need for carefully designed and conducted clinical trials to improve clinical practice and outcomes after lung transplantation. PMID- 29579770 TI - Acute Cellular Rejection: Is It Still Relevant? AB - Despite significant progress in the field of transplant immunology, acute cellular rejection (ACR) remains a very frequent complication after lung transplantation (LTx), with almost 30% of LTx recipients experiencing at least one episode of treated ACR during the first year of follow-up. Most episodes respond to the first-line immunosuppressive treatment and are rarely a direct cause of death. However, the association of ACR with later adverse outcomes, such as chronic lung allograft dysfunction, bronchial stricture, and infectious complications associated with the intensification of immunosuppression, negatively impacts long-term survival. The burden imposed on patients and health care resources is even higher in cases of refractory or recurrent ACR, which accelerates lung function decline. Although important laboratory and clinical research conducted over the last two decades has improved our understanding of the mechanisms underlying ACR, there are still many uncertainties about the risk factors for ACR, the optimal monitoring strategies, and the prediction of long term outcomes. These knowledge gaps contribute to the large variability in clinical practice among LTx centers, which renders multicenter studies of ACR challenging. In this review, we summarize current evidence on the epidemiology, pathogenesis, and risk factors of ACR. We describe diagnostic and therapeutic approaches that are currently used in the clinical practice and also review promising diagnostic tools that are under investigation. Associations between ACR and other adverse outcomes of LTx are examined. Finally, within each topic of discussion, we highlight the main areas of controversy and opportunities for future research. PMID- 29579771 TI - The Human Respiratory Microbiome: Implications and Impact. AB - Once considered a sterile site below the larynx, the tracheobronchial tree and parenchyma of the lungs are now known to harbor a rich diversity of microbial species including bacteria, viruses, fungi, and archaea. Many of these organisms, particularly the viruses which comprise the human respiratory virome, have not been identified, so their true role is unknown. It seems logical to conclude that a "healthy" respiratory microbiome exists which may be modified in disease states and perhaps by therapies such as antibiotics, antifungals, and antiviral treatments. It is likely that there is a critical relationship or equilibrium between components of the microbiome until such time as perturbations occur which lead to a state of dysbiosis or an "unhealthy" microbiome. The act of lung transplantation provides an extreme change to an individual's respiratory microbiome as, in effect, the donor respiratory microbiome is transplanted into the recipient. The mandatory ex-vivo period of the donor lungs appears to be associated with blooms of resident viral species in particular. Subsequently, allograft injury, rejection, and immune suppressive therapy all combine to create periods of dysbiosis which when combined with transient infections such as community acquired respiratory viruses may facilitate the development of chronic allograft dysfunction in predisposed individuals. As our understanding of the respiratory microbiome is rapidly expanding, based on the use of new-generation sequencing tools in particular, it is to be hoped that insights gained into the subtle relationship between the microbiome and the lung allograft will facilitate improved outcomes by directing novel therapeutic endeavors. PMID- 29579772 TI - Community-Acquired Respiratory Viruses. AB - The incidence of community-acquired respiratory viruses (CARVs) is ~15 cases per 100 patient-years after lung transplantation (LTx). Paramyxoviruses account for almost 50% of the cases of CARV infection in LTx. Most patients will be symptomatic with a mean decline of 15 to 20% in forced expiratory volume in 1 second. The attributable death rate is low in recent years 15 to 25% CARV infected LTx patients will develop chronic lung allograft dysfunction within a year after CARV infection. This risk seems to be increased in comparison to the noninfected LTx recipient.Detection rate of CARV dependent on clinical awareness, sampling, and diagnostic method with nucleic acid testing by polymerase chain reaction in bronchoalveolar lavage is the gold standard after LTx.There is no approved treatment for paramyxoviruses, most centers use ribavirin by various routes. Toxicity of systemic ribavirin is of concern and some patients will have contraindication to this treatment modality. Treatment may reduce the risk to develop chronic lung allograft dysfunction and respiratory failure. Agents under development are inhibiting viral attachment and use silencing mechanisms of viral replication. PMID- 29579773 TI - Surveillance Bronchoscopy: Is It Still Relevant? AB - The performance of bronchoscopy with bronchoalveolar lavage and transbronchial biopsy is an essential tool and skill required by any clinician caring for patients postlung transplantation. Making a confident diagnosis is crucial in initiating different treatment strategies which may be in turn hazardous to the patient in light of an inaccurate diagnosis. Having more information available for evaluation optimizes the chances of tailoring appropriate therapeutic options in this complex patient population. Performing a bronchoscopy with bronchoalveolar lavage and transbronchial biopsy indeed provides a wealth of information via microbiological, cytological, and histological samples that assist us to differentiate infection from rejection, or to confirm the presence of both. This review aims to discuss the utility of bronchoscopy postlung transplantation in the diagnosis of rejection, infection, and airway complications, as well as looking into the ongoing controversy regarding monitoring practices worldwide and safety concerns. PMID- 29579774 TI - Fungal Infections Complicating Lung Transplantation. AB - Lung transplantation is an increasingly utilized modality for treating advanced lung disease. However, lung transplant recipients (LTRs) experience high rates of infection-related mortality and, compared with other solid organ transplant recipients, are at increased risk of infectious complications given the intensity of immunosuppression employed, the presence of airway abnormalities after surgery and exposure of the allograft to the environment. Fungal infections, particularly mold infections, are problematic after transplantation as they are often associated with limited treatment options and poor outcomes. We describe the non Candida fungal infections occurring in LTRs, including their epidemiology, clinical features, and treatment. PMID- 29579775 TI - Defining Success in Lung Transplantation: From Survival to Quality of Life. AB - Lung transplantation (LT) has the potential to extend survival and improve quality of life (QOL) for patients suffering from end-stage lung disease. This review describes the many ways in which success can be defined in LT. It evaluates the improvements in survival outcomes after LT over time, and describes ways to measure the success of LT other than survival after transplantation. It also addresses the importance of patient-centered outcomes and how improvements in health-related quality of life (HRQL) are pivotal to defining success within LT. PMID- 29579776 TI - Linear and nonlinear variable selection in competing risks data. AB - Subdistribution hazard model for competing risks data has been applied extensively in clinical researches. Variable selection methods of linear effects for competing risks data have been studied in the past decade. There is no existing work on selection of potential nonlinear effects for subdistribution hazard model. We propose a two-stage procedure to select the linear and nonlinear covariate(s) simultaneously and estimate the selected covariate effect(s). We use spectral decomposition approach to distinguish the linear and nonlinear parts of each covariate and adaptive LASSO to select each of the 2 components. Extensive numerical studies are conducted to demonstrate that the proposed procedure can achieve good selection accuracy in the first stage and small estimation biases in the second stage. The proposed method is applied to analyze a cardiovascular disease data set with competing death causes. PMID- 29579777 TI - Comparing hierarchical models via the marginalized deviance information criterion. AB - Hierarchical models are extensively used in pharmacokinetics and longitudinal studies. When the estimation is performed from a Bayesian approach, model comparison is often based on the deviance information criterion (DIC). In hierarchical models with latent variables, there are several versions of this statistic: the conditional DIC (cDIC) that incorporates the latent variables in the focus of the analysis and the marginalized DIC (mDIC) that integrates them out. Regardless of the asymptotic and coherency difficulties of cDIC, this alternative is usually used in Markov chain Monte Carlo (MCMC) methods for hierarchical models because of practical convenience. The mDIC criterion is more appropriate in most cases but requires integration of the likelihood, which is computationally demanding and not implemented in Bayesian software. Therefore, we consider a method to compute mDIC by generating replicate samples of the latent variables that need to be integrated out. This alternative can be easily conducted from the MCMC output of Bayesian packages and is widely applicable to hierarchical models in general. Additionally, we propose some approximations in order to reduce the computational complexity for large-sample situations. The method is illustrated with simulated data sets and 2 medical studies, evidencing that cDIC may be misleading whilst mDIC appears pertinent. PMID- 29579778 TI - The sum of standardized residuals: Goodness-of-fit test for binary response models. AB - We propose a new goodness-of-fit statistic for evaluating generalized linear models with binary responses on the basis of the sum of standardized residuals. We derive the asymptotic distribution of the sum of standardized residuals statistic and argue that, despite its relative simplicity, it typically outperforms many of the more sophisticated currently used goodness-of-fit statistics. PMID- 29579780 TI - Multivariate joint frailty model for the analysis of nonlinear tumor kinetics and dynamic predictions of death. AB - The Response Evaluation Criteria in Solid Tumors are used as standard guidelines for the clinical evaluation of cancer treatments. The assessment is based on the anatomical tumor burden: change in size of target lesions and evolution of nontarget lesions (NTL). Despite unquestionable advantages of this standard tool, Response Evaluation Criteria in Solid Tumors are subject to some limitations such as categorization of continuous tumor size or negligence of its longitudinal trajectory. In particular, it is of interest to capture its nonlinear shape and model it simultaneously with recurrent progressions of NTL and overall survival. We propose a multivariate nonlinear mechanistic joint frailty model for longitudinal data, recurrent events, and a terminal event. In the model, the tumor size trajectory is described using an ordinary differential equation that accounts for the natural growth and treatment-induced decline. We perform a simulation study to validate the method and apply the model to a phase III clinical trial in colorectal cancer. In the results of the analysis, we determine on which component, tumor size, NTL, or death the treatment acts mostly and perform dynamic predictions of death. We compare the model with other models that consider parametric functions or splines for the tumor size trajectory in terms of goodness of fit and predictive accuracy. PMID- 29579779 TI - Late sodium current inhibitors to treat exercise-induced obstruction in hypertrophic cardiomyopathy: an in vitro study in human myocardium. AB - BACKGROUND AND PURPOSE: In 30-40% of hypertrophic cardiomyopathy (HCM) patients, symptomatic left ventricular (LV) outflow gradients develop only during exercise due to catecholamine-induced LV hypercontractility (inducible obstruction). Negative inotropic pharmacological options are limited to beta-blockers or disopyramide, with low efficacy and tolerability. We assessed the potential of late sodium current (INaL )-inhibitors to treat inducible obstruction in HCM. EXPERIMENTAL APPROACH: The electrophysiological and mechanical responses to beta adrenoceptor stimulation were studied in human myocardium from HCM and control patients. Effects of INaL -inhibitors (ranolazine and GS-967) in HCM samples were investigated under conditions simulating rest and exercise. KEY RESULTS: In cardiomyocytes and trabeculae from 18 surgical septal samples of patients with obstruction, the selective INaL -inhibitor GS-967 (0.5 MUM) hastened twitch kinetics, decreased diastolic [Ca2+ ] and shortened action potentials, matching the effects of ranolazine (10MUM). Mechanical responses to isoprenaline (inotropic and lusitropic) were comparable in HCM and control myocardium. However, isoprenaline prolonged action potentials in HCM myocardium, while it shortened them in controls. Unlike disopyramide, neither GS-967 nor ranolazine reduced force at rest. However, in the presence of isoprenaline, they reduced Ca2+ -transient amplitude and twitch tension, while the acceleration of relaxation was maintained. INaL -inhibitors were more effective than disopyramide in reducing contractility during exercise. Finally, INaL -inhibitors abolished arrhythmias induced by isoprenaline. CONCLUSIONS AND IMPLICATIONS: Ranolazine and GS-967 reduced septal myocardium tension during simulated exercise in vitro and therefore have the potential to ameliorate symptoms caused by inducible obstruction in HCM patients, with some advantages over disopyramide and beta blockers. PMID- 29579781 TI - Proportional hazard model estimation under dependent censoring using copulas and penalized likelihood. AB - This paper considers Cox proportional hazard models estimation under informative right censored data using maximum penalized likelihood, where dependence between censoring and event times are modelled by a copula function and a roughness penalty function is used to restrain the baseline hazard as a smooth function. Since the baseline hazard is nonnegative, we propose a special algorithm where each iteration involves updating regression coefficients by the Newton algorithm and baseline hazard by the multiplicative iterative algorithm. The asymptotic properties for both regression coefficients and baseline hazard estimates are developed. The simulation study investigates the performance of our method and also compares it with an existing maximum likelihood method. We apply the proposed method to a dementia patients dataset. PMID- 29579782 TI - Identification of a Golgi apparatus protein complex important for the asexual erythrocytic cycle of the malaria parasite Plasmodium falciparum. AB - Compared with other eukaryotic cell types, malaria parasites appear to possess a more rudimentary Golgi apparatus being composed of dispersed, unstacked cis and trans-cisternae. Despite playing a central role in the secretory pathway of the parasite, few Plasmodium Golgi resident proteins have been characterised. We had previously identified a new Golgi resident protein of unknown function, which we had named Golgi Protein 1, and now show that it forms a complex with a previously uncharacterised transmembrane protein (Golgi Protein 2, GP2). The Golgi Protein complex localises to the cis-Golgi throughout the erythrocytic cycle and potentially also during the mosquito stages. Analysis of parasite strains where GP1 expression is conditionally repressed and/or the GP2 gene is inactivated reveals that though the Golgi protein complex is not essential at any stage of the parasite life cycle, it is important for optimal asexual development in the blood stages.

AB - The correct characterization of aquifer parameters is essential for water-supply and water-quality investigations. Slug tests are widely used for these purposes. While free software is available to interpret slug tests, some codes are not user friendly, or do not include a wide range of methods to interpret the results, or do not include automatic, inverse solutions to the test data. The private sector has also generated several good programs to interpret slug test data, but they are not free of charge. The computer program SlugIn 1.0 is available online for free download, and is demonstrated to aid in the analysis of slug tests to estimate hydraulic parameters. The program provides an easy-to-use Graphical User Interface. SlugIn 1.0 incorporates automated parameter estimation and facilitates the visualization of several interpretations of the same test. It incorporates solutions for confined and unconfined aquifers, partially penetrating wells, skin effects, shape factor, anisotropy, high hydraulic conductivity formations and the Mace test for large-diameter wells. It is available in English and Spanish and can be downloaded from the web site of the Geological Survey of Spain. Two field examples are presented to illustrate how the software operates. PMID- 29579785 TI - Grouping methods for estimating the prevalences of rare traits from complex survey data that preserve confidentiality of respondents. AB - Originally, 2-stage group testing was developed for efficiently screening individuals for a disease. In response to the HIV/AIDS epidemic, 1-stage group testing was adopted for estimating prevalences of a single or multiple traits from testing groups of size q, so individuals were not tested. This paper extends the methodology of 1-stage group testing to surveys with sample weighted complex multistage-cluster designs. Sample weighted-generalized estimating equations are used to estimate the prevalences of categorical traits while accounting for the error rates inherent in the tests. Two difficulties arise when using group testing in complex samples: (1) How does one weight the results of the test on each group as the sample weights will differ among observations in the same group. Furthermore, if the sample weights are related to positivity of the diagnostic test, then group-level weighting is needed to reduce bias in the prevalence estimation; (2) How does one form groups that will allow accurate estimation of the standard errors of prevalence estimates under multistage cluster sampling allowing for intracluster correlation of the test results. We study 5 different grouping methods to address the weighting and cluster sampling aspects of complex designed samples. Finite sample properties of the estimators of prevalences, variances, and confidence interval coverage for these grouping methods are studied using simulations. National Health and Nutrition Examination Survey data are used to illustrate the methods.

A number of reports havesuggested that telomerase function may be involved in chronic hepatitis B (CHB) pathogenesis, but positive or negativeassociations with HCC risk remain for discussion. Mean telomere length is an indicator of biological aging and it hasbeen reported that reduction in NBV carriers compared to normal individuals. In somatic cells, telomeres containsimple, tandemly repeated G-rich sequences that frequently are reduced by 50 to 200 base pairs at each cell division.Several genome-wide association studies (GWAS) in diverse ethnic populations have revealed eleven single nucleotidepolymorphisms (SNPs) linked to telomere length. Two of these, rs398652 and rs621559, have prognostic value and couldbe used as genetic markers. This review describes current knowledge concerning telomerase activity and telomere lengthas well as significant polymorphisms in HBV-related HCC patients. In particular, to cast light on genotype-phenotypeinteractions, we used SNPnexus to evaluate effects of the two SNPs on risk of disease and complex disorders. PMID- 29579788 TI - Risk Factors for Gastric Cancer: A Systematic Review AB - Objective: Gastric cancer is one of the leading causes of death worldwide, with many influences contributing to thedisease. The aim of this study was to identify the most important risk factors. Methods: This study was conducted in2017 with a structured overview in the Science Directe, Scopus, PubMed, Cochrane, Web of Science (ISI) databases.In the first step, articles were extracted based on their titles and abstracts; the quality of 43 articles was evaluatedusing the STORBE tool. Inclusion criteria were studies carried out on human, English language (first step), year ofthe study and the study type (second step). Results: Finally, 1,381 articles were found, of which 1,269 were excludedin primary and secondary screening. In reviewing the references of the remaining 44 papers, 4 studies were added.Finally, 43 articles were selected for the quality assessment process. A total of 52 risk factors for gastric cancer wereidentified and classified into nine important categories: diet, lifestyle, genetic predisposition, family history, treatmentand medical conditions, infections, demographic characteristics, occupational exposures and ionizing radiation'.Conclusion: Several environmental and genetic factors are involved in the development of gastric cancer. Regardingthe role of changes in 'diet and lifestyle', considering appropriate nutrition and improving the level of education andawareness of people is vital for early diagnosis and timely treatment of this disease, especially in people with a familyhistory and genetic predisposition.

PMID- 29579789 TI - Risk Factors for Cholangiocarcinoma in Thailand: A SystematicReview and Meta Analysis AB - Background and objective: Cholangiocarcinoma remains a serious public health concern in Thailand. While manyof the risk factors for cholangiocarcinoma in western countries are well-recognized, it remains unclear whether theyare the same in Thailand. We set out to investigate the risk factors for cholangiocarcinoma in Thailand. Methods:Starting March 4, 2016, we reviewed studies found using pre-specified keywords on SCOPUS, Pro Quest ScienceDirect, PubMed, and online public access catalog of Khon Kaen University. Two review authors independently screenedstudies for inclusion criteria, extracted data, and assessed the studied Risk of Bias. The Newcastle-Ottawa Scale and theJoanna Briggs Institute Critical Appraisal Tools were used to assess the quality of included studies. The risk effects offactors were estimated as a pooled adjusted odds ratio with a 95% confidence interval. The heterogeneity of results wasconsidered using the I-square, Tau-square and Chi-square statistics. Results: A strong association was found betweencholangiocarcinoma and age, Opisthorchis viverrini infection, eating raw cyprinoid fish, family history of cancer, liquorconsumption, and taking praziquantel. There was only a mild association found between eating nitrite-containing foods,fresh vegetables, education, smoking behavior, and sex. No association was found between cholangiocarcinoma andeating fermented fish (Pla-ra), northeastern Thai or Chinese sausage, sticky rice, meat, chewing betel nut, or eatingfruit. There were two protective factors including fresh vegetables consumption and education attainment. Conclusion:There are unique risk factors of cholangiocarcinoma in Thailand, including age, Opisthorchis viverrini infection, eatingraw cyprinoid fish, family history of cancer, liquor consumption, and taking praziquantel. PMID- 29579791 TI - Emigration From Puerto Rico to Florida: Multivariate Analysis of Factors That Condition Attitudes of the Puerto Rican Population Toward Organ Donation for Transplant. AB - BACKGROUND: The Puerto Rican population represents one of the largest immigration groups in Florida, and this has an impact on the organ transplant donation process. Our aim was to analyze attitudes toward organ donation among Puerto Ricans who currently reside in the state of Florida (USA). METHODS: The population screened consisted of individuals >15 years old, who were born in Puerto Rico, living in Florida, and awaiting organs for transplant. All participants completed the "PCID-DTO Rios" questionnaire. Random selection was done according to stratification. Support from immigration associations in Spain was needed for advice on the locations of potential respondents. Study participation was anonymized and self-administered. RESULTS: There were 259 respondents, 37% (n = 95) were in favor of donation, 36% (n = 93) were against donation, and 27% (n = 71) were undecided. The variables associated with these attitudes were: age (P = .017); civil status (P = .021); level of education (P < .001); previous experience with donation and transplant (P < .001); attitude toward organ donation of a relative (P < .001); carrying out pro-social activities (P < .001); discussing the issue of transplant with the family (P < .001) or couple (P < .001); attitude toward incineration (P < .001), burial (P < .001), and autopsy (P < .001); fear of mutilation after donation (P < .001); and religious beliefs (P < .001). In the multivariate study, it remained an independent variable to have discussed the issue at the family level (odds ratio = 11.627; P = .009). CONCLUSION: The Puerto Rican study population residing in Florida has an unfavorable attitude toward organ donation.

AB - BACKGROUND: The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. METHODS: All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Rios") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. RESULTS: The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P < .001), previous experience with organ donation (P = .006), attitude toward cadaveric organ donation (P < .001), belief in the possibility of needing a transplant in the future (P = .016), discussing the issue with one's family (P = .007), discussing the issue with husband/wife/partner (P = .002), carrying out pro-social activities (P = .029), religious beliefs (P = .001), and understanding the risk of living kidney donation (P = .046). CONCLUSION: Attitudes toward living kidney donation among immigrant Dominicans varies between Spain and the USA, with the former showing a more positive view. PMID- 29579793 TI - Factors That Affect the Attitudes of the Bolivian Population in Spain With Regard to Organ Donation for Transplant. AB - BACKGROUND: The Bolivian population is an emerging Latin American immigrant group in Spain, several of whom have been transplanted or are awaiting transplant. We aimed to assess attitudes toward organ donation among Bolivians currently residing in Spain. METHOD: The population screened was born in Bolivia but living in Spain, stratified by gender and age. The appraisal tool used was a questionnaire that assesses attitudes toward organ donation for transplant ("PCID DTO Rios"). Support from immigration associations in Spain was needed for advice on locations of potential respondents. Survey participation was anonymized and the questionnaire was self-administered. Verbal consent was obtained before participation. RESULTS: There were 206 respondents: 49% (n = 101) in favor of donating their organs after death; 21% (n = 44) against donation; and 30% (n = 61) undecided. Their attitudes were found to be associated with level of education (P = .008), previous experience with donation and transplant (P = .011), concern regarding mutilation after donation (P = .002), knowing the attitude of their religion toward transplant (P = .001), the opinion of their partner (P < .001), and the possibility of needing a future transplant (P = .050). In the multivariate study, the main factor was having a partner in favor of organ donation (odds ratio = 16.129; P = .003). CONCLUSION: Attitudes toward organ donation among Bolivians residing in Spain are far more negative compared with rest of the Spanish population, due to various factors. PMID- 29579794 TI - Knowledge of the Brain Death Concept Among the Population of Havana, Cuba. AB - BACKGROUND: One of the main reasons against organ donation is the fear of apparent death due to ignorance of the brain death concept. Our aim was to assess knowledge about and acceptance of the brain death concept among the population of Havana, Cuba. METHODS: The population screened, stratified by gender and age, included those >15 years old and living in Havana, Cuba. The appraisal tool utilized was a questionnaire on attitude toward organ donation ("PCID-DTO Rios"). A random selection of individuals were surveyed according to the stratification. Cuba's census data were used. The participation was anonymized and self administered. The verbal consent of participants was provided. RESULTS: There were 920 respondents: 31% (n = 282) knew the concept of brain death and accepted it; 57% (n = 529) did not; and 12% (n = 109) had a misperception, or did not accept brain death as a person's death. Those who knew and accepted the concept had a more favorable attitude toward their own organ donation after death (85% vs 61%; P < .001). The psychosocial factors related to the knowledge of brain death concept were: the gender (P = .002), to make up for speaking at a family level about the organ transplant (P < .001), the couple's opinion about the organ donation (P < .001) and the religion (P < .001). CONCLUSION: The brain death concept is not well understood in the population of Havana, Cuba.

AB - INTRODUCTION: Living kidney donation is currently the most important kidney donor source in Latin America, and it is necessary to further increase its rates. OBJECTIVE: To analyze the attitude toward living kidney donation among the Santiago de Cuba's population and to determine the sociopersonal factors with which it is associated. METHOD: The population over 15 years old residing in Santiago de Cuba, stratified by sex and age, was screened. The "PCID-LKD Rios" attitude questionnaire toward living kidney donation was administered to a random selection of the people surveyed according to the stratification and the census data. The completion was anonymized and self-administered. Verbal consent was obtained. RESULTS: The study was completed by 445 people, of whom the 86% (n = 389) were in favor of living related kidney donation. This attitude is associated with the level of education (P < .001); previous experience with organ donation (P = .006); attitude toward cadaveric organ donation (P < .001); carrying out of prosocial activities (P = .010); discussion of the issue with the family (P < .001) and the significant other (P < .001); concern about mutilation after donation (P = .001); religious beliefs (P = .001); and assessment of the risk of living kidney donation (P < .001). In the multivariate study, the following variables persisted: (1) level of education; (2) attitude of cadaveric donation; (3) carrying out of prosocial activities; and (4) risk assessment of living donation. CONCLUSIONS: Living related donation is very well accepted among the Santiago de Cuba's population. PMID- 29579796 TI - Algerian Immigrants to Spain: Study of Attitude to the Donation of Organs for Transplantation. AB - INTRODUCTION: Many Africans are emigrating to the European Economic Community from countries with little knowledge of transplantation. This population has not yet been studied. OBJECTIVE: Analyze the attitude toward donation among the Algerian population living in Spain. METHODS: We studied the population born in Algeria and residing in Spain, over 15 years old, and stratified by age and sex. Attitude was surveyed using a questionnaire of organ donation for transplantation ("PCID-DTO Rios"). Support from African immigration associations was needed to advise on the location of potential respondents. The completion was anonymous and self-administered. Verbal consent was obtained to assist in the study. RESULTS: Of the 441 respondents, 27% (n = 119) were in favor of donation after death, 43% (n = 191) were against, and 30% (n = 131) were undecided. The variables associated with the attitude toward the donation were sex (P = .033), having offspring (P = .027), having commented on the subject of organ transplantation at the family level (P < .001), attitude (P < .001), religion (P < .001), and partner's opinion on organ donation and transplantation (P < .001). Only 16% of the respondents have known a transplant recipient or donor, with this subgroup having the most favorable attitude (68% vs 19%, P < .001). CONCLUSIONS: The Algerian population emigrant to Spain has a very unfriendly attitude toward the donation of their own organs. PMID- 29579798 TI - Approach of Social Groups With Little Sensitization to Organ Donation: Pilot Study in the Gypsy Population to Assess the Best Approach to Determine the Attitude Toward Organ Donation for Transplantation. AB - BACKGROUND: There are social groups with very low donation rates, and action is needed to try to reverse this situation. The goal of this study was to determine which approach is the best to use with the gypsy population in Spain to determine their attitude toward organ donation. METHODS: The study population screened was the adult gypsy population resident in Spain. An attitude questionnaire regarding organ donation for transplant ("PCID-DTO Rios: Questionnaire of "Proyecto Colaborativo Internacional Donante" about Organ Donation and Transplant [developed by Dr. Rios]") was used as the assessment instrument. In 3 gypsy towns, the patriarch was contacted, who agreed to the questionnaire and to inform the others of our presence. Two forms of action were valued: (1) a direct approach (n = 100), with personal interview; and (2) an alternative approach (n = 200), which involved leaving the questionnaire in a meeting point of the town and collecting the questionnaires at the end of the meeting. The completion was anonymous and self-administered. RESULTS: The completion level of the study was anecdotal in both groups. The direct approach presented several problems: (1) null participation to complete the questionnaire (only 12 questionnaires were collected); (2) the attempt to generate empathy and request re-evaluation generated in 78% of the cases a hostile environment; and (3) the male population presented a harder and more aggressive attitude. With the alternative approach, only 10 of the 200 questionnaires left were retrieved, 9 of them blank or painted. CONCLUSIONS: The approach of the gypsy population is complex; because of their hostile and unfavorable attitude, a more global approach is needed, with the collaboration of people of their own ethnic group. PMID- 29579797 TI - Does the Attitude Toward Organ Donation Change as a Function of the Country Where People Emigrate? Study Between Uruguayan Emigrants to the United States and Spain. AB - INTRODUCTION: The Uruguayan population is sensitized toward transplantation. However, it has not been studied how this awareness can change when emigrating to different countries. OBJECTIVE: To analyze the attitude toward cadaveric organ donation and living organ donation between the Uruguayan population residing in Florida (United States) and the Uruguayan population residing in Spain. METHOD: Adults born in Uruguay and residing in Florida and Spain were screened. The questionnaire "PCID-DTO Rios" (donation of cadaveric organs) and "PCID-DVR Rios" (living renal donation) were used. Subjects were randomly selected according to age and gender stratification. Support from Latin-American immigration associations in Spain and Florida was needed. The survey was anonymized and self administered. Verbal consent was obtained to collaborate in the study. RESULTS: Because the emigrant population to Spain is far larger than the emigrant population to the United States, a 2:1 proportional sampling was performed (n = 132). Sixty-seven percent of residents in Spain were in favor of organ donation at the time of death compared with 50% among residents in Florida (P = .082), and 100% of residents in Spain were in favor of living renal donation compared with 50% of those living in Florida (P < .001). CONCLUSIONS: The attitude toward donation is more favorable among Uruguayan emigrants to Spain than emigrants to the United States, especially in related kidney donation. PMID- 29579799 TI - Is the Incipient Community of Senegalese Emigrants to Spain in Favor of the Donation of Related Renal Live? AB - BACKGROUND: Senegalese populations are massively migrating to the southern parts of the European Union, especially Spain, France, and Italy. The attitude towards living kidney donation in this group is little known. The objective of this study was to analyze the attitude toward living kidney donation of subjects from the population of Senegalese residents in Spain. METHODS: The study subjects were the Senegalese population residing in Spain aged >15 years stratified according to age and sex, according to census data and immigrant support associations. The evaluation instrument used was an attitude questionnaire toward renal live transplant ("PCID-DVR" Rios: The questionnaire of the International Collaborative Donor Project about Living Kidney Donation ["Proyecto Colaborativo Internacional Donante sobre Donacion de Vivo Renal" in Spanish] developed by Dr. Rios). Support of African immigration associations was used to advise on the location of potential respondents. Fulfillment of the questionnaire was anonymous and self administered. Verbal consent was requested for collaboration in the study. Student t tests, the chi2 test, Fisher exact test, and a logistic regression analysis were used in the statistical analysis. RESULTS: The study included 293 respondents. Overall, 62% (n = 181) were in favor of renal live donation (relatives and close friends); 38% (n = 112) did not consider the possibility of renal live donation or they had doubts. This attitude is not related to social variables or general information (P > .05). The variables associated with this attitude (P < .05) were related to the family environment (especially with the partner) and the risk assessment of donating a living kidney. CONCLUSIONS: Based on these results, the Senegalese population that has immigrated to Spain has a very unfriendly attitude toward renal live donation. PMID- 29579800 TI - Psychometric Characteristics of the Attitude Questionnaire Toward the Donation of Organs for Transplant (PCID-DTO-RIOS). AB - INTRODUCTION: Most psychosocial attitude studies for donors are not evaluated and are not valid. Validated questionnaires are necessary to compare results and guarantee that they measure what they are intended to measure. OBJECTIVE: To analyze the psychometric characteristics of the attitude questionnaire toward the donation of one's own organs after death. We evaluated PCID-DTO RIOS (Questionnaire of "Proyecto Colaborativo Internacional Donante" about organ donation and transplant; donacion y trasplante de organos in Spanish), developed by Dr Rios, for its validation in a Spanish-speaking population. METHOD: A sample of 600 Spaniards over 18 stratified by age and gender according to the center were included. The PCID-DTO-RIOS was used, which allows determination of the factors that condition that attitude. Structured analysis was used in several stages, with an initial description of the data, exploratory factorial analysis, item analysis, and internal factor consistency. RESULTS: The 20 items of the questionnaire are grouped into 4 factors, which explain 63.203% of the total variance. By factors, this is distributed as follows: factor 1 (6 items) 26.287%; factor 2 (7 items) 24.972%; factor 3 (4 items) 6.834%; and factor 4 (3 items) 5.110%. The analysis of the items and the internal consistency measured through Cronbach alpha (alpha1 = .95, alpha2 = .80, alpha3 = .74, and alpha4 = .64) support the four-factor composition, with alpha = 0.834. CONCLUSIONS: The questionnaire PCID-DTO-RIOS is composed of 4 factors that explain a high percentage of the attitude toward the donation of one's own organs after death. PMID- 29579801 TI - Guinean Population Emigrant to Spain Has Very Little Awareness of the Donation and Transplantation of Organs. AB - INTRODUCTION: The Guinean population is an emerging group in Europe, but the group's awareness of organ donation and transplantation has not been studied. OBJECTIVE: To analyze the attitude toward organ donation among the population born in Guinea living in Spain. METHODS: The population older than 15 years, born in Guinea, and resident in Spain was studied, stratified by age and sex, according to census data and immigrant assistance associations. The valuation tool used was the attitude questionnaire toward organ donation PCID-DTO RIOS (questionnaire on "Donor International Collaborative Project" on organ donation and transplantation developed by Dr Rios). A random selection of people to survey was based on stratification. Support from African immigration support associations was needed to advise on the location of potential respondents. The completion was anonymous and self-administered. A descriptive statistic was performed, and Student t, chi2, and Fisher tests and a logistic regression analysis were applied. RESULTS: In all, 181 Guineans were surveyed, of whom 32% (n = 58) were in favor of the donation of their own organs after death, 32% (n = 57) were against, and 36% (n = 66) were undecided. The variables that are associated with attitude toward donation are separated mainly into 4 large groups (P < .001): (1) knowledge about the process of donation and organ transplantation; (2) attitude toward the manipulation of the body; (3) religious variables; and (4) sociofamily variables, especially in relation to the couple. CONCLUSIONS: The Guinean population emigrant to Spain has an unfriendly attitude toward organ donation. PMID- 29579802 TI - Nigerian Immigrant Population in Spain Is Little Sensitized to Living-Related Kidney Donation. AB - BACKGROUND: The Nigerian population is an emerging group in Spain and in Europe, but their sensitization toward living kidney donation has not been studied. The aim of this work was to analyze the attitude toward related renal donation while alive among the population born in Nigeria resident in Spain. METHODS: A population older than 15 years born in Nigeria and resident in Spain, stratified by age and sex, was studied with the use of the attitude questionnaire about living kidney donation, "PCID-DVR-Rios." People were randomly selected based on stratification. African immigration support associations advised on the location of potential respondents. Completion of the questionnaire was anonymous and self administered. Verbal consent was requested to assist in the study. Statistical methods included Student t test, chi2, Fisher exact test, and logistic regression analysis. RESULTS: A total of 179 respondents were included in the study: 70% (n = 125) were in favor of living-related kidney donation, and 30% (n = 54) remained against or undecided. This attitude was associated with different psychosocial factors: marital status (P = .001), having offspring (P = .029), risk assessment of live donation (P < .001), partner's opinion about donation (P < .001), previous relationship with donation and/or transplantation (P < .001), religion (P < .001), and fear of mutilation after donation (P < .001). In the multivariate analysis, the previous relationship with donation and/or transplantation (odds ratio, 8.064) persisted as the main related factor. CONCLUSIONS: The Nigerian immigrant population in Spain has a less favorable attitude toward living kidney donation than the native western European and Spanish population. PMID- 29579803 TI - Attitude Toward Organ Donation Related to Personal Preferences for the Final Disposition of the Dead Body in Nursing Students in Southeast Spain. AB - INTRODUCTION: In organ donation and transplantation (ODT) and in nursing students, it is important to know the preferences about the final destination of the body once deceased. Whether these future professionals are afraid of this issue could influence their attitude toward ODT and future donation rates. OBJECTIVE: To analyze the attitude of nursing students toward cremation, burial, and autopsy and to determine the factors affecting this attitude. METHODS: A sociologic, interdisciplinary, multicenter, and observational study included nursing diploma students (n = 750) from 2010 to 2011 at 3 universities in the southeast of Spain. A validated questionnaire (PCID-DTO RIOS) was self administered and completed anonymously. RESULTS: Questionnaire completion rate was 92% (n = 687), with 71% (n = 486) of students accepting cremation as a body treatment after death. Those who were not worried about the possible mutilation of the body after donation (P < .05) and those who were in favor of deceased donation (P < .001) had a greater degree of acceptance. Of the students, 43% (n = 278) would accept burial of their body, which was related with being in the second year (P < .05) of study. Finally, 86% (n = 586) of students would accept an autopsy being carried out, if necessary, and this was related with the attitude toward ODT (P = .004). CONCLUSIONS: A high percentage of nursing students would accept an autopsy being carried out. This degree of acceptance was related with a favorable attitude toward organ donation. The appropriate training of future nurses in ODT process will optimize their promotion. PMID- 29579804 TI - Attitude Toward Organ Donation and Transplantation in Veterinary Students: A Multicenter and Stratified Study in Spain. AB - BACKGROUND: Veterinarians often hold decision-making positions in the public health care system and can therefore influence public opinion about organ donation and transplantation (ODT). The aim of this work was to analyze the attitude of Spanish veterinary students toward ODT, because they may influence public opinion in the future, and to determine the factors that condition it. METHODS: This was a sociologic, interdisciplinary, multicenter, observational study in Spain. The study population was students studying for a veterinary degree in Spain (n = 9000), and a sample of 2815 students (confidence of 99% and precision of +/-1%) was stratified by geographic area and academic year. A validated questionnaire of attitude toward ODT (PCID-DTO-Rios) was self administered and anonymous. RESULTS: Of the 2815 selected students (2790 plus the 0.9% per type of sample), 2650 completed the questionnaire (response rate, 94.14%): 83% (n = 2207) of the respondents were in favor of donation and 17% against. The following main variables were related to a favorable attitude: being female (odds ratio [OR], 0.752; P = .034); knowing a donor (OR, 1.834; P = .003); having discussed the matter with one's family (OR, 1.587; P = .002); having spoken about the subject in social circles with friends (OR, 1.633; P < .001), and being in favor of donating a deceased family member's organs (OR, 2.403; P < .001). CONCLUSIONS: Seventeen percent of Spanish veterinary students were not in favor of ODT. It is important to know the factors that determine their attitude, because this will make it possible to optimize the resources invested in campaigns to promote ODT and to take more specific action. PMID- 29579805 TI - Multivariate Analysis of Factors That Influence the Attitude of the Ecuadorian Population Resident in Spain Toward Living-Related Kidney Donation. AB - BACKGROUND: The Ecuadorian population is the largest Latin-American immigrant group in Spain. Currently, several Ecuadorians have received transplants or are awaiting transplants in Spain. The aim of this work was to analyze the attitude toward living kidney donation among the Ecuadorian population residing in Spain. METHODS: The population screened were born in Ecuador, residing in Spain, and >15 years old, stratified by gender and age, and appraised with the use of the questionnaire on attitude toward organ donation for transplantation "PCID-DVR Rios." Support from immigration associations in Spain was used to advise on the location of potential respondents. The completion was anonymous and self administered. Verbal consent was obtained. Statistics included Student t test, chi2, Fisher exact test, and logistic regression analysis. RESULTS: A total of 461 respondents were included: 80% (n = 367) were in favor of living-related kidney donation (for a relative or close friend). This attitude was associated with psychosocial variables that persisted in the multivariate study: 1) female gender (odds ratio [OR], 3.086; P = .001); 2) considering oneself a potential kidney receptor in the future (OR, 16.949; P = .002); 3) economic incentive in the donation (OR, 100; P = .004); and 4) knowing the attitude of their religion toward transplantation (OR, 32.258; P < .001). CONCLUSIONS: Living-related donation is accepted among the Ecuadorian population residing in Spain and is associated with sociopersonal and religious factors. PMID- 29579806 TI - Living Kidney Donation Questionnaire (PCID-DVR-Rios): Validation and Psychometric Characteristics in a Spanish-Speaking Population. AB - BACKGROUND: The attitude toward living kidney donation is important for certain promotion campaigns, however, there are few validated questionnaires in this regard. The aim of this work was to analyze the psychometric characteristics of the attitudes questionnaire about living renal donation, PCID-DVR-Rios (Cuestionario del Proyecto Colaborativo Internacional Donante sobre Donacion de Vivo Renal [Questionnaire of the International Collaborative Donor Project on Living Kidney Donation] developed by Dr Rios) for the validation of the questionnaire in population of Spanish speakers. METHODS: The sample studied represented the population >18 years of age, native and resident of Spain, stratified by age and sex. The measurement instrument was the PCID-DVR-Rios questionnaire. Analysis of data was structured in several stages: an initial description of the data, exploratory factor analysis, item analysis, and internal consistency of the factors. RESULTS: The questionnaire consists of 11 items, distributed in 3 factors of 6, 3, and 2 items. This structure accounts for 63.995% of the total variance. By factors, the variance is distributed as follows: factor 1: 38.461%; factor 2: 14.228%; and factor 3: 11.306%. The analysis of items and internal consistency supported the trifactorial composition. Each factor is internally consistent (alpha1 = .80; alpha2 = .70; alpha3 = .55). CONCLUSIONS: The analyzed dimensions of the PCID-DVR Rios questionnaire to analyze attitude toward living kidney donation showed a good fit in terms of factorial validity and internal consistency values. PMID- 29579807 TI - Council of Europe Black Sea Area Project: International Cooperation for the Development of Activities Related to Donation and Transplantation of Organs in the Region. AB - BACKGROUND: In 2011, the European Directorate for the Quality of Medicines & Healthcare of the Council of Europe launched a 3-year collaborative project to address the organ shortage and improve access to transplant health services in Council of Europe member states in the Black Sea area (Armenia, Azerbaijan, Bulgaria, Georgia, Moldova, Romania, Turkey, Ukraine, and the Russian Federation) through the development of safe and ethical donation and transplantation programs. OBJECTIVE: Support the development of donation and transplantation programs through close interstate cooperation between national health organizations and relevant stakeholders. METHODOLOGY: Several work packages (WP) were established: WP1, project coordination (European Directorate for the Quality of Medicines & Healthcare); WP2, development and implementation of an effective legislative and financial framework (Czech Republic and France); WP3, establishment of National Transplant Authorities (Italy and Portugal); and WP4, clinical practices (DTI Foundation). Data collection, surveys, and expert visits allowed for the collection of first-hand information from each participant country at national, regional, and hospital levels. RESULTS: Data analysis showed the positive impact of the project represented by a tendency to increase the total donation rates (per million people) in the participant countries (2011 vs 2013): Azerbaijan, +7.3; Armenia, -0.7; Georgia, +3.3; Bulgaria, +0.9; Moldova, +2.5; Ukraine:, +0.8; Romania, +2.3; and Turkey, +2.7. CONCLUSIONS: Increases in total donation rates are the result of a number of initiatives in the Black Sea area, including the stepwise implementation of legislative, organizational and institutional country-specific recommendations tailored by the CoE, efforts of the respective Ministries of Health in each country and synergism with other European projects in the region. These countries should invest further in implementing the recommendations that emerged from this project to improve their organ donation and transplantation programs and progress toward self-sufficiency. PMID- 29579808 TI - The Process of Kidney Donation in the Northern Macroregional Area of Parana, Brazil. AB - INTRODUCTION: The high morbidity and mortality caused by chronic kidney disease, and consequently, the increase in the need for kidney transplants, makes the evaluation of the kidney donation process relevant to verifying the service's fragility with the goal of optimizing this process. OBJECTIVE: This study analyzed the process of kidney donation in the Northern Macroregional area of Parana, Brazil. METHOD: This was a cross-sectional and retrospective evaluation study based on 586 reports of deaths provided by the Intra-Hospital Organ Donation and Transplant Tissue Commissions to the Organ Procurement Organization of the Northern Macroregional area of Parana in Brazil between 2011 and 2015. Data were analyzed by descriptive statistics, prevalence ratio, and Poisson regression. RESULTS: The prevalence of kidney donation was higher among the deaths of individuals younger than 61 years of age (P = .018) due to traumatic brain injury and hemorrhagic cardiovascular accident (P < .001), assisted in private institutions (P = .037), and occurring in the second half of the year (P = .015). CONCLUSION: The process of kidney donation was mainly compromised due to the refusal of the family and was associated with clinical and organizational aspects. PMID- 29579809 TI - Access to Grafts in a Liver Transplant Center: Does It Rely on the Severity of the Waiting List Population? AB - BACKGROUND: The number of transplants performed relies, partially, on recipients' variables on the waiting list. The goal of this study was to compare recipients from a high-volume liver center in Argentina with the rest of the country. METHODS: This study was a retrospective analysis of liver transplant recipients nationally between January 2013 and April 2017. It involved extracting data from the open database CRESI-SINTRA (the Argentinian database of the National Procurement Organization, an equivalent to the United Network for Organ Sharing); expressing results by percentages, medians, and interquartile ranges (IQRs); and comparing the national population with the population transplanted at Hospital El Cruce (HEC). The Mann-Whitney U test was used for analysis. RESULTS: Nationally, 1434 liver transplants were performed. A total of 177 (12.34%) were emergency status; 811 (56.6%) were by the Model for End-Stage Liver Disease (MELD) (n = 759)/PELD (Pediatric End-Stage Liver Disease) (n = 52), with a median graft assignment position of 5 (IQR, 3-10) in 57.2 days (IQR, 11-217). Median MELD access was 29 points (IQR, 24-33). A total of 446 (31.1%) had MELD exceptions; 249 (55.8%) of these were due to Milan hepatocellular carcinoma. At the HEC, 167 liver transplantations were performed; 26 (15.6%) were emergency status and 97 (58.1%) by MELD (none PELD). Their median graft assignment position was 4 (IQR, 4 16) in 19.1 days (IQR, 4-90); median MELD access was 28 points (IQR, 24-31). Forty-five patients (26.9%) had MELD exceptions; 31 (68.9%) were due to hepatocellular carcinoma. CONCLUSIONS: Our center has a larger proportion of recipients transplanted by emergency status and MELD, similar MELD access, and less waiting list time, reflecting our wide policy of liver graft acceptance. PMID- 29579810 TI - Trend Analysis of Organ and Tissue Donation for Transplantation. AB - BACKGROUND: The goal of this study was to identify the tendency toward donations of tissue and organs from donors with brain death between 2001 and 2016 as registered by an organ procurement organization in Sao Paulo City. METHODS: This quantitative, retrospective, exploratory study encompassed all Tissue and Organ Donation Terms signed between 2001 and 2016. A logistic regression model was applied to verify whether there was an upward or downward trend in donation. RESULTS: After statistical analysis, a significant change trend was identified in skin, bones, valve, vessel, heart, lung, and pancreas donations, indicating an increase in the donation rate through the years. The donation rate did not show changes over the years for donations of liver, kidneys, and corneas. CONCLUSIONS: The decision-making process regarding organ and tissue donation is restricted not only to the dilemma of whether to donate but another question then arises as well: which organs and tissues are to be donated? The discrepancy between the authorization for organ donation and the authorization for tissue donation, as well as the option for one or another organ and/or tissue, must be thoroughly examined because these factors directly affect the number of transplants and acquirements effectively accomplished. These factors may be related to explaining to one's relatives aspects of the surgery, body reassembling, and usage of such organs and/or tissues. They may also be related to the lack of knowledge concerning organ donation and the symbolism represented by the organ and/or tissue, among other factors. PMID- 29579811 TI - Bone Tissue Donation: Tendency and Hurdles. AB - INTRODUCTION: The aim of this study was to identify the percentage of bone tissue donation in a brain death situation and the tendency of donation rate of this tissue in an organ procurement organization in the county of Sao Paulo from 2001 to 2016. It is a retrospective and quantitative study, based on the Organ and Tissue Donation Term of donors who died of brain death between 2001 and 2016. METHODS: A logistic regression model was applied, and the odds of donation were identified throughout the years, regarding the odds ratio different from zero. Finally, it was measured the accuracy of the odds ratio through the confidence interval. RESULTS: The analysis has shown a significant change on the trend of bone donation (P < .001). In this case, the odds ratio was >1, indicating that the donation rate has increased. However, the percentage of growth is still considered low. CONCLUSIONS: The study evidences a growth trend regarding the donation of bone tissue, but the percentage is still too low to adequately meet the demand of patients who need this modality of therapeutic intervention. It is believed that educational campaigns of donation are not emphasizing the donation of tissues for transplantation, which may be directly impacting their consent rates. PMID- 29579812 TI - Neurocritical Patient Characteristics Related to Brain Death. AB - BACKGROUND: The lack of viable organs for transplantation led to the creation in Argentina of the Glasgow 7 Program based on the detection and follow-up of acute neurologic patients admitted with Glasgow scores <=7 in selected hospitals. The objective of this study was to determine the likelihood of hospitalized acute neurologic patients progressing to brain death (BD) based on several variables, including age, sex, and admission diagnosis. METHODS: This study was a retrospective cohort analysis of data obtained from the SINTRA (Procurement and Transplantation National Information System) database between 2006 and 2015. Independent variables included the following: age, sex, and diagnosis at admission; ischemic stroke; spontaneous intracerebral hematoma (SIH); subarachnoid hemorrhage (SH); anoxia, meningitis; penetrating head injury (PHI); closed head injury; and tumors. A multivariate analysis was performed adjusting the diagnosis at admission according to age and sex. RESULTS: A total of 31,877 patients were included: 19,308 (61%) patients died and 9736 (30%) evolved to BD. Overall, 36% of women and 28% of men evolved to BD (relative risk, 0.87 [95% confidence interval (CI), 0.86-0.89]; P < .001). In the multivariate analysis adjusted for age and sex, we observed the following: SIH OR, 1.79 (95% CI, 1.69 1.9; P < .001); ischemic stroke OR, 0.82 (95% CI, 0.73-0.92; P < .001); SH OR, 2.33 (95% CI, 2.16-2.52; P < .001); anoxia OR, 0.71 (95% CI, 0.64-0.79; P < .001); closed head injury OR, 0.41 (95% CI, 0.38-0.43; P < .001); PHI OR, 2.64 (95% CI, 2.38-2.94; P < .001); and tumors OR, 1.07 (95% CI, 0.93-1.24; P = .31). CONCLUSIONS: Thirty percent of the patients who entered the Glasgow 7 Program evolved with BD. The characteristics most likely to result in BD were age, female sex, PHI, SH, and SIH. PMID- 29579813 TI - Does Traumatic Brain Injury by Firearm Injury Accelerates the Brain Death Cascade? Preliminary Results. AB - Brain death (BD) triggers a series of pathophysiological events similar to multiple-organ dysfunction. Traumatic brain injury (TBI) due to firearm injury (FAI) causes lesions that could lead to BD. Patients admitted to the ICU due to severe TBI that evolved to BD were studied, including those caused by FAI; the 2 groups were compared with the objective of demonstrating that the support of the deceased donor by TBI due to FAI is more unstable and of shorter duration than the one related to TBI by another cause. Preliminary results demonstrated that the individuals with TBI by FAI died in BD in a higher percentage than the individuals with TBI caused by accidents (83% vs 41%). The donor treatment period was lower in individuals who presented TBI by FAI. These individuals needed higher doses of noradrenaline as vasopressor support for their treatment, without showing a statistically significant difference (P = .15), compared with individuals whose BD cause was TBI caused by accident. PMID- 29579814 TI - Epidemiologic and Evolutionary Profile of Patients With Subarachnoid Hemorrhage With Glasgow Coma Scale Score of 8 or Less Who Entered the Follow-Up Program of the National Institute of Donation and Transplantation. AB - INTRODUCTION: The improvement in understanding the process that determines the death of an individual and his or her evolution toward brain death allows organization and planning of health policies, optimization of clinical activity and management of organ and tissue procurement processes for transplantation. OBJECTIVE: This study sought to analyze the epidemiological and evolutionary profile of patients with spontaneous subarachnoid hemorrhage (SAH) with a Glasgow Coma Scale score (GCS) <=8 who entered follow-up in the Neurocritical Patient Monitoring Program (SPN) of Instituto Nacional de Donacion y Trasplante (INDT), Uruguay. MATERIALS AND METHODS: SPN, a monitoring and follow-up program for neurocritical patients with GCS <= 8, prospectively collected data from 5 public and private intensive care units. A total of 160 patients with SAH with GCS <=8 in 10 years were identified and analyzed using a 2-step nested model. Firstly, independent risk factors for mortality were identified, tested in different combinations, and one of them was selected using the best correct classification rate. In the second step, risk factors for evolution to brain death were investigated. RESULTS: The mortality of patients with SAH with GCS <=8 was 68%. Mortality for GCS 3 was 82%, significantly higher than for other values on the scale (P = .0025). Female sex (P = .011) and arterial hypertension (P = .017) were associated with higher mortality. There was no significant association between mortality and age, Acute Physiology and Chronic Health Evaluation score, and Simplified Acute Physiologic Score II. Administration of analgesia and/or sedation was a protective factor (P < .0001). Of the patients who died, 50% were in brain death. We did not find clinical elements capable of identifying an increased probability of developing brain death. CONCLUSIONS: Based on epidemiological data, models capable of improving the understanding of the complex process of death and particularly brain death can be generated. More studies are needed to explore the differential evolutionary behavior of critical neurological illness. PMID- 29579815 TI - Utility of Transcranial Doppler in the Coordination of Transplants: 10 Years of Experience. AB - Transcranial Doppler (TCD) integrated to multimodal neuromonitoring of neurocritical patients is a useful tool in the clinical follow-up. A retrospective and descriptive study of 194 patients who were admitted into the intensive care unit (ICU) was carried out from December 2007 to February 2017. We analyzed the distribution of study frequencies with respect to the pathologies that motivated them, the characteristics of patients who evolved to brain death (BD), and most frequent patterns of cerebral circulatory arrest. Ninety-four of the patients that evolved to BD required 126 studies during their follow-up. The insonation of the 2 middle cerebral arteries and the basilar artery was the most frequent combination (30%). Most frequent reasons of request for a TCD included apnea test intolerance and reduction of waiting time and sedation analgesia. These 10 years of experience have enabled a deeper understanding of the cerebral hemodynamics and the identification of common patterns of high resistance to different pathologies (subarachnoid hemorrhage, severe skull trauma, anoxic ischemia, ammonia encephalopathy) that explain the severity of the acute brain injury, related to the increase of brain volume and its deleterious consequence: the elevation of intracranial pressure (ICP). In the same way, because invasive ICP monitoring is not available in all cases, with a tomographic scan of the skull we have been able to observe a correlation of some imaging signs suggestive of intracranial hypertension with patterns of high resistance obtained by the TCD in the pathologies mentioned. We recommend that each ICU that assists neurocritical patients should have TCD equipment and the skilled personnel to carry out the technique. PMID- 29579816 TI - Systodiastolic Separation Expresses Cerebral Circulatory Arrest? AB - There is a situation before the cerebral circulatory cessation phase, the systodiastolic separation in transcranial Doppler (TCD), which may raise doubts to the operator technician who performs it. A total of 266 studies were performed in 188 neurocritical patients over a 9-year period: 88 cases (77%) corresponded to cerebral circulatory arrest (CCA) which accompanies brain death (BD); 9 (5%) presented the systodiastolic separation pattern. In 1 of those 9 there was persistence of cough reflex and spontaneous breathing; in 5, CCA was not reached; only 3 evolved to CCA. The finding of a minimal persistent neurologic semiology is a categoric fact that would rule out the clinical correlation between this pattern and BD diagnosis. PMID- 29579817 TI - Sterility and Safety Validation for Transport Packaging of Organs and Tissues. AB - The bags used in the transport of organs and tissues must be sterile, nontoxic, pyrogen free, and must serve as a barrier throughout their useful life. The goal of this study was to show the sterility, safety, and functionality of the bags subjected to irradiation, through validated procedures and techniques. The selected sterilization method was the use of gamma radiation. The sterilization dose was determined based on validated standards for the sterilization of medical products, ISO 11137-2: 2013 and ISO/TS 13004: 2013, using the Verification Dose Maximum method on samples belonging to 3 manufacturing lots. The ISO 10993-5: 2009 standard was used in the cytotoxicity tests, by means of extracts test and quantitative technique of MTT, 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide. The tests to determine the expiration date of the kit were performed by ASTM F1980, accelerated aging, and ASTM D3078 to evaluate hermeticity. The irradiation dose validated to reach the required sterility safety level was 22.5 kGy. The constituent materials and the sterilization method do not generated cellular toxicity, and the product was not modified during the simulated time of 5 years. Sterilization by irradiation is a method that leaves no residue, does not harm the properties of the material because it is conducted in cold, and as the sterilizing agent, the energy absorbed by the product is highly penetrating and can be treated in its final packaging, with no risk of postcontamination. It is for this reason that it is prioritized over other methods of sterilization. PMID- 29579818 TI - Single-Center Long-Term Follow-Up of Kidney Donors in Argentina (Hospital Italiano de Buenos Aires). AB - INTRODUCTION: Living kidney donor (LKD) transplantation is increasing due to organ shortage. Clinical studies have shown that the risk of developing end-stage renal disease (ESRD) in donors is similar to that in the general population. Our goal was to evaluate postdonation renal outcomes assessed by glomerular filtration rate (GFR), proteinuria, and blood pressure. METHODS: A total of 210 LKD transplants were performed at Hospital Italiano de Buenos Aires between 2000 and 2014. Postdonation outcomes were analyzed in 109 donors. GFR was assessed by 24-hour creatinine clearance (as 24-hour ClCr) and estimated using the Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Additionally, we correlated the predonation renal functional reserve (RFR) with postdonation GFR. Donor results were compared to the expected GFR (adjusted to age and single kidney). Other renal outcome indicators measured were albuminuria and blood pressure, and they were compared (predonation and postdonation) using univariate analysis. RESULTS: A total of 109 patients were followed up for 47 +/- 34 months (range, 12-168): 70% were female, age at donation was 48.58 years (range, 25-70), and predonation serum creatinine was 0.85 +/- 0.17 mg/dL. Postnephrectomy GFR (24-hour ClCr) was significantly lower compared to predonation GFR (105.38 +/- 21.78 mL/min/1.73 m2 vs 90.14 +/- 17.78 mL/min/1.73 m2). However, postdonation GFR was not significantly different compared to the expected GFR. No differences were found for blood pressure or albuminuria. Age >50 and an RFR (<20%) was associated with a lower GFR. CONCLUSIONS: In this population of LKD, renal outcome (24-hour CrCl, albuminuria, and blood pressure) was within the expected outcome for healthy individuals after uninephrectomy. PMID- 29579819 TI - Correlation of the Glomerular Filtration Rate Measured With the Use of DTPA-Tc99m in Live Kidney Donors With Equations Based on Creatinine and Cystatin C. AB - BACKGROUND: Renal donation leads to a risk of developing chronic kidney disease, with an incidence of 0.47%. To evaluate for its presence, formulas based on serum creatinine are used, but up to 80% of these formulas underestimate the glomerular filtration rate (GFR) in donors. The aim of this work was to confirm the highest correlation of the GFR as measured with the use of DTPA-Tc99m with the GFR as estimated by means of the formula based on serum cystatin C (CKD-EPI creatinine cystatin C) in healthy kidney donors. METHODS: In this observational, analytic, cross-sectional study, the GFR of kidney donors was determined >=1 year after donation by means of DTPA gammagram and estimation with the use of conventional formulations and with cystatin C. RESULTS: Of 112 donors, 38 (34%) were included, 20 (60%) were female, with an overall average age of 40 years, 36.5 months after donation, and body mass index of 25.5 kg/m2. Correlation with the GFR as measured by means of DTPA gammagram was better with the use of CKD-EPI cystatin C (0.402; P = .020) and CKD-EPI creatinine-cystatin (0.549; P < .001) than the conventional formulas. Linear correlation with serum cystatin C was 0.825 (P < .001; 95% confidence interval, -105.3 to -63.2) for the CKD-EPI cystatin C formula, 0.77 (P < .001; -89.9 to -48.1) for the CKD-EPI creatinine-cystatin formula, and 0.525 (P = .002; -91.1 to -23.2) for DTPA-Tc99m scintigraphy. CONCLUSIONS: There is a strong correlation between estimate the GFR by equations based on cystatin C and the measurement of the GFR by DTPA-Tc99m gammagram. PMID- 29579820 TI - Correlation of the Renal Cortex Volume With the Glomerular Filtration Rate in Live Donors for Renal Transplantation. AB - INTRODUCTION: As a pretransplantation evaluation, renal function is determined by the glomerular filtration rate (GFR) with the use of renal scintigraphy (RS) and the estimated glomerular filtration rate (eGFR). To date, there are few studies that correlate renal cortex volume with eGFR determined with renal gammagram (GR) and eGFR by equations (Cockroft-Gault, Modification of Diet in Renal Disease, and Chronic Kidney Disease Epidemiology Collaboration equation) in Latin American living donors. AIM: This study sought to determine whether there is correlation of the volume of the renal cortex by Herts equation with the GFR determined with renal gammagram (GFR-GR). PATIENTS AND METHODS: This was an analytical, observational, and cross-sectional study. A review of the donor charts from January 1, 2014, to December 1, 2014, with a complete clinical file, kidney measurements, predonation tomography volume, and eGFR by different formulas and by renal scintigraphy. RESULTS: Thirty-three donors were included, 51.5% male and 48.5% female. The mean age was 38.58 +/- 10 years, with an average volume of 127.83 +/- 28.30 mL, with diethylenetriamine-pentaacetate (DTPA) of 54.80 +/- 7.13 mL/min/1.73 m2 in the donated kidney. Spearman correlation showed the best association with the Herts equation (r = 0.346) reaching significance (P = .049) when comparing the different equations against the GFR with DTPA. Using the Bland Altman method, the lowest variability and best significance was verified with the same equation compared to the other formulas (P = .0002). CONCLUSIONS: There is no consensus regarding which is the best formula for calculating the GFR of both kidneys. Of the different formulas, the one that best correlated with the GFR was the Herts method, which uses the volume of the kidney. PMID- 29579821 TI - Experience and Security of the Hand-Assisted Laparoscopic Nephrectomy of a Living Donor in a Public Health Center. AB - BACKGROUND: Hand-assisted laparoscopic nephrectomy (HALDN) is currently the procedure of choice for obtaining living donor kidneys for transplantation. In our institution, it has been the standard procedure for 5 years. Previous studies have shown the same function of the graft as that obtained by open surgery, with a lower rate of bleeding and no differences in complications. We sought to demonstrate the experience and safety of HALDN compared with open donor nephrectomy in healthy donors for kidney transplantation. METHODS: A retrospective analytical observational study was conducted, reviewing the records of the living donors for kidney transplant undergoing open donor nephrectomy or HALDN in our center from March 1, 2009, to March 1, 2016. Renal function was assessed by the estimated glomerular filtration rate by the Modification of Diet in Renal Disease method before and after donation, as well as bleeding (mL), and complications (according to Clavien), performing a comparative analysis between the two techniques using parametric or nonparametric tests. RESULTS: A total of 179 living donor nephrectomies were performed during the study period-31 open donor nephrectomy (17.3%) and 148 HALDN (82.7%)-without relevant baseline differences, except for creatinine. HALDN has a shorter surgical time (156,473 +/ 87.75 minutes vs 165,484 +/- 69.95 minutes) and less bleeding (244.59 +/- 416.08 mL vs 324.19 +/- 197.986 mL) and a shorter duration of hospital stay (3.74 +/- 1.336 days vs 4.75 +/- 1.226 days). There were no significant differences in surgical complications at 30 days, or graft loss reported; there were 3 conversions (1.7%) from the HALDN to the open technique. There were no differences in renal function in the donors or recipients at the 5th day or the month after surgery. CONCLUSIONS: Laparoscopic nephrectomy has replaced open surgery as the gold standard for living kidney donors. HALDN is a safe and feasible procedure when compared with open donor nephrectomy, achieving a shorter surgical time with less bleeding, and no difference in the number of complications. This procedure lowers costs by decreasing the duration of the hospital stay, making is feasible to perform it at any institution with appropriately trained personnel. PMID- 29579822 TI - Highly HLA Sensitized Kidney Transplant Patients in a Transplant Center. AB - INTRODUCTION: Approximately 10% to 30% of patients on renal transplant waiting lists are sensitized, which gives them more time on the waiting list. Transplantation in this setting has a greater risk of rejection and decreased graft survival. New strategies of donor allocation through virtual crossmatching and optimization of immunosuppressive therapies in induction and maintenance have allowed the allocation of organs for this population, which in other circumstances would not be chosen for a kidney transplant. OBJECTIVE: To describe the experience of renal transplantation in highly sensitized patients with a panel reactive antibody of >80% in a transplant center, through virtual crossmatching, discarding unacceptable antigens, and without desensitization treatment. METHODS: An observational, descriptive, retrospective case series study was conducted on highly sensitized kidney transplant patients with a panel reactive antibody of >=80% from 2010 to 2016. RESULTS: A total of 10 highly sensitized transplant patients were identified. Six patients were women, all of whom had a history of pregnancy; all patients had undergone blood transfusions, and 40% had undergone a first transplant. Average time spent on dialysis was 148.5 months, and on the waiting list, 45.8 months. Average follow-up was 42 months (range, 10-84 months). The estimated glomerular filtration rate by the Chronic Kidney Disease Epidemiology Collaboration method at year 1 was 75 mL/min/1.73 m2 body surface. Nine patients at 1 year posttransplantation had graft and patient survivals of 100%, as did 5 patients at >3 years posttransplantation. CONCLUSIONS: Renal transplantation based on virtual crossmatching is a good alternative for highly sensitized patients. PMID- 29579823 TI - Impact of Clinical Simulation Training in Transplantation. AB - INTRODUCTION: The Hospital El Cruce is a high complexity center that performs transplants, both the procurement and the implant of organs and tissues. To deal with the low availability of organs and tissues from cadaveric donors it has been implemented the training through clinical simulation. OBJECTIVE: To assess if continuous training through procurement clinical simulation workshops modifies the production and quality indicators of organ and tissue procurement for transplantation in the hospital. MATERIALS AND METHODS: The workshop focuses on the procurement difficulties as detailed: workshops with high fidelity simulators: detection of potential donor; certification of death; treatment and selection of potential donor; workshops with role play actors; communication of the patient's death; and request for the last will of the deceased. A retrospective study was performed to compare between two periods the procurement activity. These periods defined 30-month before and after the opening of the workshop, as periods 1 and 2. RESULTS: In period 1, 44 patients underwent organ transplantation and 64 patients a tissue transplantation. After training through workshops (period 2), the number of patients increased to 71 for organ transplantation and 116 for tissue transplantation. CONCLUSIONS: Assessment of the two periods indicates that the production and quality indicators of organ and tissue procurement improved in the second period. Continuous training through procurement clinical simulation workshops is highlighted within all tasks carried out in the hospital. Clinical simulation is a motivating factor for the development of this activity in the hospital. PMID- 29579824 TI - Peripheral Blood Regulatory T Cells Are Diminished in Kidney Transplant Patients With Chronic Allograft Nephropathy. AB - BACKGROUND: Our aim in this study was to assess peripheral blood CD4+CD25+FOXP3+ regulatory T cell (Treg) levels in patients with chronic allograft nephropathy (CAN) 1 year after kidney transplantation. METHODS: Twelve renal transplant patients with an initial onset of CAN, 12 patients with chronic kidney disease (CKD) stage G5 on dialysis, and 13 healthy control individuals were evaluated regarding the proportion of Tregs in their peripheral blood via flow cytometry. RESULTS: The renal transplant patients with CAN had a significantly lower proportion of Tregs than the hemodialysis CKD patients and healthy controls (P < .0001). In contrast, the hemodialysis CKD patients showed higher levels of Tregs than the renal transplant patients with CAN and the healthy controls (P < .0001). CONCLUSION: The high level of peripheral blood Tregs in the hemodialysis CKD patients suggests a chronic inflammatory state. However, the low frequency of Tregs in the peripheral blood from the renal transplant patients with CAN suggests an unfavorable prognosis for allograft immune tolerance. PMID- 29579825 TI - Renal Transplantation in Second-Level Private Hospitals in the State of Mexico. AB - BACKGROUND: Kidney transplantation (KT) is the replacement therapy of choice in patients with end-stage renal disease (ESRD). Here we show a cohort of kidney transplant recipients from the period of May 1994 to May 2016 in 2 2nd-level private hospitals from the city of Toluca in the state of Mexico. METHODS: We checked the clinical files of all the patients that received KT in the period of study. RESULTS: We report 25 KT: 23 performed in Sanatorio Toluca and 2 in Sanatorio Florencia; 16 (64%) male and 9 (26%) female; mean age 36.03 +/- 15.9 years (range, 10-66); 19 (76%) hemodialysis and 9 (24%) continuous ambulatory peritoneal dialysis before KT; ESRD etiology unknown in 16 (64%), diabetes in 5 (20%), IgA nephropathy in 2 (8%), and other in 2 (8%); living donors in 13 (52%) and deceased donors in 12 (48%); blood group 0+ in 18 (72%), A+ in 5 (20%), and B+ in 2 (8%); 21 (84%) with 0 and 4 (16%) with 1 HLA mismatch; and delayed graft function in 8 (32%), of which 7 were from deceased donors and 1 from a living donor. All 25 (100%) had a functional kidney at 1 year of follow-up. Immunosuppression regime consisted of multitarget maintenance therapy in all 25 (100%): cyclosporine in 18 (72%) and tacrolimus in 7 (28%). We used only methylprednisolone (MTP) as induction therapy. There were only 2 cases (8%) of acute rejection during the 1st 6 months of follow-up, and both responded to treatment with MTP. CONCLUSIONS: KT is the treatment of choice for patients with ESRD. The obtained results using only an MTP induction regime are satisfactory, with graft and patient survivals of 100% in the 1st year of follow-up. PMID- 29579826 TI - Cardiac Remodeling in Structure and Function Six Months After Kidney Transplantation. AB - BACKGROUND: Cardiovascular disease accounts for 35% to 50% of the causes of mortality in chronic kidney disease. The majority of patients in substitution therapy in Mexico are subdialyzed owing to limited economic resources. This produces more cardiac deterioration than described in the statistics and has a direct impact on the prognosis of kidney transplantation. The aim of this work was to demonstrate and to quantify the improvement in the echocardiographic parameters 6 months after renal transplantation in patients with stable renal function. METHODS: This was an observational, analytic, prospective study of 23 patients with chronic kidney disease who received transplants in 2016 and had a glomerular filtration rate >=80 mL/min (Chronic Kidney Disease-Epidemiology Collaboration) 6 months after transplantation. RESULTS: Echocardiographic results showed an increase in the left ventricular ejection fraction from 57.17 +/- 10.46% to 64.09 +/- 9.8%, an increase in the right ventricular ejection fraction from 0.56 +/- 0.09% to 0.60 +/- 0.08% and a reduction of the pulmonary arterial systolic pressure from 44.57 +/- 13.88 mm Hg to 39.74 +/- 11.04 mm Hg. There were also decreases in mitral regurgitation from 1.0 to 0.43, tricuspid insufficiency from 1.35 to 0.43, pulmonary insufficiency from 0.48 to 0.04, and aortic insufficiency from 0.35 to 0.04, all of these significant with P < .05. CONCLUSIONS: There was a significant improvement in cardiovascular function in our population 6 months after transplantation, despite the fact that renal transplantation is performed with greater cardiac deterioration than described in patients in other countries. PMID- 29579827 TI - Epidemiologic Study and Genotyping of BK Virus in Renal Transplant Recipients. AB - BK virus (BKV) infection occurs during childhood and remains latent in the urinary tract. The virus is reactivated in immunosuppressed patients, particularly in those with cellular immunity deficiency, allowing its detection in urine and blood. Nephropathy caused by the virus in renal transplantation recipients may lead to graft failure. The purpose of this study is to know the prevalence of BKV variables in renal transplantation recipients and to evaluate their clinical evolution through molecular methods of "in house" development. Urine and peripheral blood samples from 66 renal transplantation recipients from the province of Buenos Aires, Argentina, were systematically analyzed every 3 months as well as when there was graft dysfunction. Renal biopsies, which were included in the BKV detection study, were performed on those patients with graft dysfunction. Genotyping of 24 BKVs was performed, and the following distribution was found: 21 (87.5%) belonged to subtype I, 3 (12.5%) to subtype II. BKV belonging to subtypes III or IV were not found. As regards subtype I subgroups, the following were identified: 1 (4.76%) from Ia, 10 (47.61%) from Ib1 and 10 (47.61%) from Ib2. Presence of subgroup Ic was not shown. Viremia presented in 33.33% of cases, whereas 75% corresponded to subgroup Ib 1. Genotype Ib1 is prevailing in Southeast Asia, while Ib2 is prominent in Europe. Although an important proportion of the inhabitants of the province of Buenos Aires are European descendants, the prevailing genotype is Ib1, the Asian type. Genotyping might be related to the evolution of the disease in the recipient. PMID- 29579828 TI - Chronic Pain Treatment With Cannabidiol in Kidney Transplant Patients in Uruguay. AB - BACKGROUND: Chronic pain is a major therapeutic problem in kidney transplant patients owing to nephrotoxicity associated with nonsteroidal antiiflammatory drugs. Benefits in chronic pain treatment with cannabidiol (CBD) have been reported. This study assesses the effect, safety, and possible drug interactions in kidney transplant patients treated with CBD for chronic pain. METHODS: We assessed patients who asked to receive CBD for pain treatment. Doses were increased from 50 to 150 mg twice a day for 3 weeks. Creatinine, blood count, liver function, liver enzymes, and drug levels were determined every 48 hours the first week and then once a week thereafter. RESULTS: We assessed 7 patients with a mean age of 64.5 years (range, 58-75 years). CBD initial dose was 100 mg/d, CBD dose reduction to 50 mg/d has been done on day 4 to patient 1 for persistent nausea. Tacrolimus dose reduction in patient 3 was undertaken on days 4, 7, and 21 owing to persisting elevated levels (even before CBD) and itching, and on day 21 in patient 5. Tacrolimus levels decreased in patient 2 but were normal in the control 1 week later. Patients on cyclosporine were stable. Adverse effects were nausea, dry mouth, dizziness, drowsiness, and intermittent episodes of heat. CBD dose decrease was required in 2 patients. Two patients had total pain improvement, 4 had a partial response in the first 15 days, and in 1 there was no change. CONCLUSIONS: During this follow-up, CBD was well-tolerated, and there were no severe adverse effects. Plasma levels of tacrolimus were variable. Therefore, longer follow-up is required. PMID- 29579829 TI - Mortality Analysis of Acute Liver Failure in Uruguay. AB - BACKGROUND: Acute liver failure (ALF) is a syndrome with high mortality. OBJECTIVE: Describe characteristics and outcomes of patients with ALF in Uruguay, and identify factors associated with mortality. METHODS: A retrospective analysis of 33 patients with ALF was performed between 2009 and 2017. RESULTS: The patients' median age was 43 years, and 64% were women. Average Model for End Stage Liver Disease (MELD) score at admission was 33. The median referral time to the liver transplant (LT) center was 7 days. The most common etiologies were viral hepatitis (27%), indeterminate (21%), autoimmune (18%), and Wilson disease (15%). Overall mortality was 52% (71% of transplanted and 46% of nontransplanted patients). Dead patients had higher referral time (10 vs 4 days, P = .008), higher MELD scores at admission (37 vs 28) and highest achieved MELD scores (42 vs 29; P < .001), and higher encephalopathy grade III to IV (94% vs 25%, P < .001) than survivors. Patients without LT criteria (n = 4) had lower MELD score at admission (25 vs 34, P = .001) and highest achieved MELD score (27 vs 37, P = .008) compared with the others. Patients with LT criteria but contraindications (n = 7) had higher MELD scores at admission (38 vs 31, P = .02), highest achieved MELD scores (41 vs 34, P = .03), and longer referral time (10 days) than those without contraindications (3.5 days) or those without LT criteria (7.5 days, P = .02). Twenty-two patients were listed; LT was performed in 7, with a median time on waiting list of 6 days. CONCLUSIONS: ALF in Uruguay has high mortality associated with delayed referral to the LT center, MELD score, and encephalopathy. The long waiting times to transplantation might influence mortality. PMID- 29579830 TI - Acute Liver Failure-25 Years at a Single Center: Role of Liver Transplantation in the Survival of Adult Patients. AB - BACKGROUND: Acute liver failure (ALF) leads to high morbidity and mortality and is characterized by an accelerated deterioration of hepatic function in patients without prior liver disease. The survival rate is <15% without liver transplantation (LT). The aim of this study was to describe the population of patients with ALF in the Unit of Liver Transplantation of the University of Campinas, Brazil, from 1991 to 2017, comparing those submitted and not submitted to LT. METHODS: The patients were divided into 2 groups: 1, listed but not transplanted; and 2, transplanted. RESULTS: There were 73 patients with ALF listed for LT, with a mean age of 33.6 years, 49 (67.1%) female and 24 (32.9%) male. Group 1, with 32 patients, had a mean age of 29.3 years; 26 (81.25%) died on the waiting list; 6 (8.45%), with a mean age of 12.33 years, were removed from the list because of recovery of liver function. Considering only adult patients, the mortality without LT was 96.29%. Group 2 had 41 patients, with a mean age of 37.1 years, and a 30-day survival of 41.02%. Thus, LT led to a significant improvement in the survival of adult patients with ALF. The time of surgery, packed red blood cells, and intraoperative plasma, were associated with LT survival after logistic regression study, whereas age, body mass index, bilirubin, international normalized ratio, creatinine, sodium, and Model for End Stage Liver Disease score were not. CONCLUSIONS: ALF affects an active age range, and LT decreases mortality; there was no good preoperative prognostic indicator to assess which patients would benefit from transplantation. PMID- 29579831 TI - Acute Liver Failure Induced by Carthamus tinctorius Oil: Case Reports and Literature Review. AB - BACKGROUND: Acute liver failure (ALF) is a clinical syndrome that results from the abrupt loss of liver function in a patient without previous liver disease. The most frequent causes are viral hepatitis, drug induced, and autoimmune disease, but in 20% of cases no cause is identified. Carthamus tinctorius (safflower) oil is used as a dietary supplement for weight loss and antioxidant. There are 4 cases described in the literature of ALF induced by the use of this substance. The objective of this study was to report 3 cases of ALF treated at the Clinical Hospital of the State University of Campinas that suggest the use of C tinctorius oil as a probable etiologic factor. CASE REPORTS: The 3 patients had a diagnosis of ALF according to the King's College criteria. All had a history of ingestion of this oil for weight loss. During etiologic evaluation, viral hepatitis, autoimmune diseases, or any other drug cause were excluded, thus pointing to C tinctorius oil as the triggering factor. All 3 patients underwent liver transplantation: 2 had good postoperative evolution, and 1 died 12 days after the procedure. CONCLUSIONS: Two cases are described in which the hepatic insufficiency induced by C tinctorius oil was successfully treated through liver transplantation. This highlights the risk of misuse of this substance for weight loss. PMID- 29579832 TI - Characteristics of Liver Transplantation in Argentina: A Multicenter Study. AB - INTRODUCTION: There is a lack of information regarding outcomes after liver transplant in Latin America. OBJECTIVES: This study sought to describe outcomes after liver transplant in adult patients from Argentina. METHODS: We performed an ambispective cohort study of adult patients transplanted between June 2010 and October 2012 in 6 centers from Argentina. Only patients who survived after the first 48 hours postransplantation were included. Pretransplantation and posttransplantation data were collected. RESULTS: A total of 200 patients were included in the study. Median age at time of transplant was 50 (interquartile range [IQR] 26 to 54) years. In total, 173 (86%) patients had cirrhosis, and the most frequent etiology in these patients was hepatitis C (32%). A total of 35 (17%) patients were transplanted with hepatocellular carcinoma. In patients with cirrhosis, the median Model for End-Stage Liver Disease (MELD) score at time of liver transplant was 25 (IQR 19 to 30). Median time on the waiting list for elective patients was 101 (IQR 27 to 295) days, and 3 (IQR 2 to 4) days for urgent patients. Almost 40% of the patients were readmitted during the first 6 months after liver transplant. Acute rejection occurred in 27% of the patients. Biliary and vascular complications were reported in 39 (19%) and 19 (9%) patients, respectively. Renal failure, diabetes, and dyslipidemia were present in 40 (26%), 87 (57%), and 77 (50%) at 2 years, respectively. CONCLUSIONS: We believe the information contained in this article might be of value for reviewing current practices and developing local policies. PMID- 29579833 TI - Tumor Biology as Predictor of Mortality in Liver Transplantation for Hepatocellular Carcinoma. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with the Milan criteria considered to be the gold standard for patient selection for liver transplantation (LT). MATERIALS AND METHODS: We performed a descriptive observational study, reviewing 20 years of experience of LT in patients with HCC in the Fundacion Valle del Lili in Cali, Colombia. Subgroup analysis was undertaken for periods 1999 to 2007 and 2008 to 2015. RESULTS: Fifty-seven cases with a pretransplant HCC diagnosis were reviewed. In the first period patients within the Milan criteria had a recurrence-free survival at 5 years of 66.6%, and in those who exceeded the Milan criteria, recurrence-free survival was 75%. In the second period, patients within the Milan criteria, recurrence-free survival at 5 years was 93.5%, and in those who exceeded the Milan criteria, recurrence-free survival was 75.7%. No statistically significant difference was found in either period. For patients with mild and moderate tumor differentiation, the relapse survival rate at 5 years was 69.4% (95% confidence interval [CI] 35.8-87.8) and 74.7% (95% CI 44.5-90), respectively. All patients with poor tumor differentiation relapsed and died within 3 years. CONCLUSION: Global and recurrence-free survival among patients who met and patients who exceeded the Milan criteria was not significantly different, suggesting an expansion of the Milan criteria to include potential recipients who were previously excluded. Obtaining histologic differentiation and identifying vascular invasion will provide a more worthwhile contribution to LT decision making. PMID- 29579834 TI - Liver Transplantation in Hepatitis C-Infected Patients: Experience From a South American Transplant Center. AB - BACKGROUND: Around 2.4% of the world's population is infected with hepatitis C virus (HCV), and it is the most common cause of liver transplantation (LT) in the world. Latin America (LA), with nearly 9% of the world population, has had a continuous increase in the number of LTs per year. Yet, due to the lack of mandatory data collection and a well-developed health-care system, access to transplantation is limited in most LA countries. We report the first LA experience of HCV-infected LT patients. METHODS: We performed a retrospective cohort study by reviewing the medical histories of all HCV-infected LT patients between 1996 and 2016 who acquired HCV before their LT, at the Fundacion Valle del Lili, Cali, Colombia. RESULTS: Between January 1996 and December 2015, a total of 770 LTs were performed, of which 75 had a cirrhotic liver due to HCV infection. With a median follow-up time of 24.4 months (interquartile range [IQR] 4.7-61.2 months), patient survival was 44.9% and 66.9% for the time periods 1996 2006 and 2007-2015, respectively. Hepatocellular carcinoma (HCC) was present in 30.6% of the patients, and overall postoperative complications had an incidence of 80%. CONCLUSIONS: This is the first report of LT in HCV-infected patients in Colombia and in LA. Our results are comparable to those of other transplant centers worldwide with regard to postoperative complications and patient survival. Patients with LT in the 1996-2006 time frame had higher morbidity and mortality. Studies including larger numbers of patients are needed to determine the reason for this finding. PMID- 29579835 TI - Risk Factors of Mortality After Liver Transplantation in Uruguay. AB - INTRODUCTION: Identification of predictive factors of mortality in a liver transplant (LT) program optimizes patient selection and allocation of organs. OBJECTIVE: To determine survival rates and predictive factors of mortality after LT in the National Liver Transplant Program of Uruguay. METHODS: A retrospective study was conducted analyzing data prospectively collected into a multidisciplinary database. All patients transplanted since the beginning of the program on July 2009 to April 2017 were included (n = 148). Twenty-nine factors were analyzed through the univariate Kaplan-Meier model. A Cox regression model was used in the multivariate analysis to identify the independent prognostic factors for survival. RESULTS: Overall survival was 92%, 87%, and 78% at discharge, 1 year, and 3 years, respectively. The Kaplan-Meier survival curves were significantly lower in: recipients aged >60 years, Model for End-Stage Liver Disease score >21, LT due to hepatocellular carcinoma (HCC) and acute liver failure (ALF), donors with comorbidities, intraoperative blood loss beyond the median (>2350 mL), red blood cell transfusion requirement beyond the median (>1254 mL), intraoperative complications, delay of extubation, invasive bacterial, and fungal infection after LT and stay in critical care unit >4 days. The Cox regression model (likelihood ratio test, P = 1.976 e-06) identified the following independent prognostic factors for survival: LT for HCC (hazard ratio [HR] 4.511; P = .001) and ALF (HR 6.346; P = .004), donors with comorbidities (HR 2.354; P = .041), intraoperative complications (HR 2.707; P = .027), and invasive fungal infections (HR 3.281; P = .025). CONCLUSION: The survival rates of LT patients as well as the mortality-associated factors are similar to those reported in the international literature. PMID- 29579836 TI - Early Bacterial Pneumonia After Hepatic Transplantation: Epidemiologic Profile. AB - BACKGROUND: Postoperative pulmonary complications are major cause of morbidity and mortality in patients receiving liver transplantation (LT), particularly bacterial pneumonia occurring within the first 100 days after transplantation. Our aim in this study was to determine the incidence, microorganisms involved, associated factors, and morbidity of bacterial pneumonia presenting in the first 100 days posttransplant. METHODS: We performed a cohort study in which patients receiving liver transplantation were included prospectively in our national database (Database of Infections in Transplantation of Solid Organs). The study period was from July 14, 2009 to July 24, 2015. RESULTS: One hundred six patients were transplanted during the 6-year period. We documented 9 bacterial pneumonia cases with an incidence of 8.5 per 100 patients; 2 patients had hospital-acquired pneumonia (HAP) and 7 had ventilator-associated pneumonia (VAP). In 4 of the 9 bacterial pneumonia cases, patients presented with bacteremia. Eleven microorganisms were isolated these 9 patients. Microbiologic diagnosis methods included 5 cases of alveolar bronchoalveolar lavage (BAL), 1 case of BAL and pleural fluid puncture, 1 case of pleural fluid puncture, and 1 case through sputum study. Of the 11 isolated organisms, 9 corresponded to Gram-negative bacilli (GNB): Klebsiella spp, n = 3; Acinetobacter baumannii, n = 4; Morganella morganii, n = 1; and Pseudomonas aeruginosa, n = 1. Regarding the resistance profile, 7 presented with a multiresistance profile (MDR) and extreme resistance (XDR). Univariate analysis identified the Model for End-Stage Liver Disease (MELD) pretransplant score as a factor associated with developing pneumonia (P < .001, 95% confidence interval [CI] 2.872-10.167), and early extubation, before 8 hours posttransplant, as a protective factor (P = .008; relative risk [RR] 0.124; 95% CI 0 .041-0.377). Hospital stay was longer in patients with pneumonia compared to those without pneumonia (P < .0001, 95% CI 17.79-43.11 days). There was also an increased risk of death in patients with pneumonia (RR 17.963; 95% CI 5106-63,195). CONCLUSIONS: Early bacterial pneumonia after hepatic transplantation is associated with higher morbidity and mortality. At our center, 4 of 9 patients had bacteremia. GNB cases with MDR and XDR profiles are predominant. Early extubation is a protective factor. PMID- 29579837 TI - Corneal Donor Profile and Evolution of Corneal Donation in a Brazilian State Where the Number of Individuals on the Waiting List Reached Zero But Increased Again. AB - BACKGROUND: In most countries, the amount of corneal graft tissue available for transplantation is insufficient to meet demand. In 2010, there were 459 patients on the waiting list for corneal transplantation (WLCT) in Espirito Santo (ES), a Brazilian state with 3,885,000 inhabitants. Several strategies were implemented to reduce the number of individuals on the WLCT, which reached zero in 2011. Studies on the evolution of corneal donation contribute to reducing the WLCT worldwide. The aim of this study was to describe the evolution of corneal donation in ES and the profile of corneal donors from 2010 to 2013. METHODS: This was a retrospective study. The data were collected from records referring to donations of corneas and from the archives of the Center for Organ Procurement and Distribution of ES. Statistical software was used to perform descriptive analysis of the data. RESULTS: The sample consisted of 1359 donors, aged 46.82 +/ 17.32 (mean +/- standard deviation), 70.1% of whom were male. Most of the consent forms for donation were signed by the sons of the donors. In 2011, there was a major increase (105%) in the number of corneal transplants compared with 2010; consequently, the number of patients on the WLCT reached zero, but increased again, reaching 139 patients in 2013. CONCLUSION: This study shows that strategies to increase corneal donations should be continued even after reduction or elimination waiting time on the WLCT.

PMID- 29579838 TI - Endoscopic Treatment for Vesicoureteral Reflux in Recurrent Urinary Tract Infections in Kidney Transplant: Experience of One Center. AB - Vesicoureteral reflux (VUR) after renal transplantation in adult patients has been reported. In renal transplant recipients, symptomatic urinary tract infection can cause high morbidity despite improved immunosuppressive and antibiotic treatment. In our country there have been few reported cases about use of copolymer of dextranomer and hyaluronic acid (DX-HA) injection in a renal transplant. We present 3 cases of recurrent or complicated infections with evidence of high-grade VUR, which were treated with DX-HA. Only 1 case had a partial remission; however, there were no episodes of urinary tract infection in 12 months of follow-up. Suburethral injection is an endoscopic treatment modality with low morbidity in our country. PMID- 29579840 TI - Teenagers in Rural Areas Faced With Organ Donation and Transplantation. AB - INTRODUCTION: In rural areas it is common to find unfavorable attitudes toward organ donation, and therefore it is important to find out the attitude and profile of new generations for improving predisposition to organ donation in these areas. Our objective was to analyze the attitude toward organ donation and the related variables of teenagers in a rural area. MATERIALS AND METHODS: Students in the final year of compulsory education (mostly 15-16 years of age) were selected from secondary schools in a rural area in southeastern Spain (n = 319; population density <300 inhabitants/km2). The instrument of measurement used was a validated psychosocial questionnaire. Completion was anonymous and self administered. Descriptive statistical analysis, Student t test, chi2 test, and multivariate analysis were employed. RESULTS: There was a completion rate of 96% (n = 306). Overall, 65% (n = 200) were in favor of donating their organs, 30% (n = 90) were undecided, and 5% (n = 16) were against. Attitude toward the donation of one's own organs was related with sex (P = .015), previous experience of organ donation or transplantation (P = .046), comment on the topic of organ donation within the family (P = .003; odds ratio 2.155), knowing one's mother's opinion about the matter (P = .021), knowing the correct concept of brain death (P = .012; odds ratio 2.076), and religion (P = .014). CONCLUSIONS: A favorable attitude of teenagers in rural areas toward organ donation is slightly higher than in the adult population and is determined by many psychosocial variables, above all family discussion about organ donation and transplantation and correct knowledge of the brain death concept. PMID- 29579841 TI - Importance for the Elderly of Discussion in the Family and Society About Attitude Toward Organ Donation. AB - BACKGROUND: The aging of the population has changed some of the approaches to the organ donation and transplant (ODT) process, such as considering elderly people as potential donors. We aimed to assess social and family discussions among the elderly about ODT and its effect on their attitude toward organ donation. METHODS: A study was carried out at 2 publicly-funded social centers for the elderly. Contact was made with individuals >65 years of age (n = 120) to seek their participation in the study. A questionnaire was distributed to them with questions about ODT. A descriptive assessment was performed with the Student t test and chi2 test used for statistical analysis. RESULTS: The completion rate was 87% (n = 104). Of the respondents with a partner and children, 48% had discussed the topic of ODT. It was found that talking about the subject with one's partner, children, or friends had a favorable influence on attitude compared with when this was not done (93%, 86%, and 83% vs 19%, 30%, and 31%, respectively; P < .001). In addition, the opinion of one's partner and children toward ODT also had an influence; if favorable, the respondent's attitude was more favorable, compared with when they did not know their opinion (92% to 88% vs 58% to 37%, respectively; P < .001). Other ODT-related variables did not affect their attitude (P > .05). CONCLUSIONS: Almost half of the elderly people had discussed ODT socially or with their family. This discourse has a favorable influence on their attitude toward organ donation and, therefore, it is important to encourage social and family dialog among this group. PMID- 29579842 TI - Teenagers and Their Future Role in Transplantation: An Analysis of Their Attitudes Toward Solid Organ Xenotransplantation. AB - INTRODUCTION: It is important to determine the level of social acceptance of xenotransplantation, especially in places where there are preclinical xenotransplantation projects. In this sense, it is important to know the attitude of teenagers, given that their attitude could have an influence on this kind of donation in the future. OBJECTIVES: The aim of this study is to analyze the attitudes of teenagers toward xenotransplantation and to determine the variables affecting their attitudes. MATERIAL AND METHODS: A random simple was obtained of students who were between 12 and 16 years of age in secondary schools in the southeast of Spain (n = 3633). Their attitudes were assessed with the use of a validated psychosocial questionnaire about xenotransplantation (PCID-XenoTx Rios). The questionnaire was completed anonymously and was self-administered. Descriptive statistical analysis, Student t, and chi2 tests were used. RESULTS: The completion rate was 97% (n = 3531). With regard to animal organ donation for humans, 44% (n = 1569) would be in favor, 22% (n = 784) against, and 34% (n = 1178) undecided. Attitude was related to knowing a transplantation patient (P = .02), believing that transplant organ needs are not covered (P = .004), having received information about organ donation and transplantation (ODT) on television and from schools (P = .001), family discussion about ODT (P < .001), attitude of the respondent's parents (P < .001), and attitude toward human donation (P < .001). CONCLUSIONS: More than half of the teenagers had unfavorable attitudes toward xenotransplantation as this was determined by factors related to knowledge of and previous information about ODT, the attitude of one's family, and attitudes toward the different types of human organ donation. PMID- 29579843 TI - Short-term Results From a Training Program to Improve Organ Donation in Uncontrolled Donation After Circulatory Death. AB - BACKGROUND: In all organ transplantation programs, election of the proper protocol relies primarily on the professionals involved in the detection of potential donors. The objective of our study was to assess the impact of a series of prehospital training sessions, as well as to develop several positive feedback strategies within the uncontrolled organ donation after circulatory death (uDCD) program in our city. METHODS: A before-after intervention study was carried out in 3 steps. First, professionals enrolled in the Emergency Health Services Agency 061 (EPES-061) program underwent specific training to identify potential donors. Second, a specific logotype was designed to alert emergency health care professionals that in cases where cardiopulmonary resuscitation was ineffective and after treatment of all potentially reversible causes, the "chain of survival" should be considered a "chain of opportunities." Third, a positive feedback strategy was put in place, whereby each time a donation was procured, the EPES 061 personnel that had identified the potential donor were notified by phone and in a personal letter. RESULTS: The mean age for donors was 50.5 years of age (interquartile range 37-52.5), and 89.5% of all donations came from male subjects. Positive feedback letters and phone calls, including information on final outcome, were provided to the appropriate personnel in 100% of the cases. Postintervention information showed an increase in both eligible and utilized donors. CONCLUSIONS: Interventions outside the hospital setting that facilitate optimal implementation of the uDCD program are an essential part of this strategy to increase the donor pool and make the wait shorter for transplant patients. PMID- 29579844 TI - Postoperative Care in Kidney Transplantation: A Comparison Between Controlled and Uncontrolled Donation After Circulatory Death. AB - Recent research in kidney transplantation has revealed differences in the evolution of renal function among patients transplanted from 2 alternative programs for donation after circulatory death (DCD). A retrospective, observational, single-center study was carried out from 2013 to 2016 at a level III hospital intensive care unit (ICU) to assess the progression of kidney recipients after transplants from uncontrolled DCD (uDCD) or controlled DCD (cDCD). The following variables were collected for data analysis: demographics, comorbidities, type of donation, lactate, hemoglobin and glucose levels at ICU admission, creatinine concentration at ICU admission, at-hospital ward transfer, at-hospital discharge, radioisotope imaging results, ICU and in-hospital length of stay, and mortality. There were 87 patients eligible for analysis, 42.5% of which were uDCD recipients. Improvement in kidney function was significantly delayed after uDCD compared with cDCD. A multivariate analysis showed that both uDCD and lactate levels at ICU admission increase the risk of poor outcome after renal transplantation. No deaths were registered in either patient group. Our results suggest that kidney transplantation recipients from uDCD recover renal function at a slower rate than patients transplanted from cDCD, a factor that does not affect mortality. PMID- 29579845 TI - Results of Controlled Donation After Circulatory Death in a Third-Level Hospital. AB - OBJECTIVE: To investigate the characteristics and evolution of controlled donation after circulatory death (DCD) type III. MATERIALS AND METHODS: Observational and retrospective study of controlled DCD type III of donors conducted from 2014 to 2016. Clinical data, intensive care unit (ICU) stay, cause of death, warm ischemia time, and total time were collected. Delayed graft function (DGF) and survival of renal transplant were also registered. Qualitative variables are described as frequencies and absolute values and quantitative variables as medians and interquartile ranges. RESULTS: A total of 21 donors were collected; 71% (15) were males, median age was 55 years (interquartile range [IR] 48-72), and median ICU stay was 7 days (IR 4-12). The main cause of death was anoxic encephalopathy (57%, 12), followed by intracerebral hemorrhage (28%, 6). In 48%, withdrawal of life support occurred in the operating room, and 98% of donors were preserved by abdominal super-rapid cannulation technique. Average warm ischemia time was 20 minutes (IR 16-24), and total ischemia time was 26 minutes (IR 23-34). Of the donations, 57% were livers and 90% were kidneys. Out of 42 kidneys donated, 54% (23) of them were valid. Median renal transplant hospital stay was 18 days (IR 6-24), and 46% develop DGF. Survival at discharge was 100%. CONCLUSION: DCD type III ensures a source of organs. The main cause of death was anoxic encephalopathy. Most donors were able to donate some solid organ. PMID- 29579846 TI - Combined Flush With Histidine-Tryptophan-Ketoglutarate and University of Wisconsin Solutions in Liver Transplantation: Preliminary Results. AB - INTRODUCTION: Ischemia reperfusion injury (IRI) is the main cause of early allograft dysfunction (EAD) and subsequent primary allograft failure (PAF). OBJECTIVES: The purpose of this study is to compare IRI, EAD, and PAF in liver transplantation in a cohort of patients perfused with histidine-tryptophan ketoglutarate (HTK) solution and University of Wisconsin (UW) solution versus HTK alone. METHODS: A randomized trial was performed to compare outcomes in liver recipients who underwent transplantation surgery in the University Regional Hospital of Malaga, Spain. Forty patients were randomized to two groups. Primary endpoints included IRI, EAD, PAF, re-intervention, acute cellular rejection, retransplantation, arterial complications, and biliary complications at postoperative day 90. RESULTS: Postoperative glutamic oxaloacetic transaminase (1869.15 +/- 1559.75 UI/L vs. 953.15 +/- 777.27 UI/L; P = .004) and glutamic pyruvic transaminase (1333.60 +/- 1115.49 U/L vs. 721.70 +/- 725.02 U/L; P = .023) were significantly higher in patients perfused with HTK alone. A clear tendency was observed in recipients perfused with HTK alone to present moderate to severe IRI (7 patients in the HTK + UW solution group vs. 15 patients in the HTK-alone solution group; P = .06), EAD (0 patients in the HTK + UW solution group vs. 0 patients in the HTK-alone solution group; P = .76), and PAF (3 patients in the HTK + UW solution group vs. 8 patients in the HTK-alone solution group; P = .15). CONCLUSIONS: Initial perfusion with HTK solution followed by UW solution in liver transplantation improves early liver function as compared to perfusion with HTK alone. PMID- 29579847 TI - Living Donor in Renal Transplantation: Minimizing Risks. AB - In recent years, the broadening of indications for renal transplantation, together with the progressive reduction of donations following brain stem death, has led to living donation being considered in increasing numbers of cases for renal transplantation. To investigate this further, it is necessary to assess the impact it has on the postoperative outcomes in the intensive care unit (ICU). Our group conducted a retrospective, observational, single-center study from 2013 to 2016 to evaluate differences in outcomes between living and cadaveric kidney donation both during ICU admission and total hospitalization. We compared differences in characteristics between living and deceased graft recipients including demographics, comorbidities, analytical data, radioisotope imaging test results, complications, ICU and hospital ward length of stay, and mortality. In all, 387 patients were eligible for analysis, and 13% received living donor grafts. Our results demonstrate that this group had significantly fewer complications, shorter length of hospital stay, and reduced mortality in comparison with recipients of cadaveric donor grafts. The better postoperative outcomes from living donor grafts could result from careful selection of the donor and less inflammatory injury, minimizing risk in the postoperative period. PMID- 29579848 TI - Anti-HLA Antibodies After Precocious Transplantectomy by Vascular Thrombosis. AB - BACKGROUND: Our objective in this study was to determine the effects of early renal transplantectomy on patients and the production of anti-human leukocyte antigen (anti-HLA) antibodies. METHODS: Between January 2003 and May 2017, we analyzed a group of patients for the presence of specific HLA class I and/or II donor-specific antibodies (DSA), their panel-reactive antibodies (PRA), and the time period in which the antibodies were still detectable after transplantectomy. RESULTS: Anti-HLA antibodies were detected in 60.8% of patients, 60.8% and 52.2% of those patients had anti-class I and anti-class II antibodies, respectively. DSA were detected in 91.7% of the anti-HLA class I patients. Class II DSA were detected all of the patients with anti-HLA class II antibodies. The average (mean +/- SD) PRA levels in our patients after transplantectomy was 60 +/- 34% in class I and 63 +/- 36% in class II. CONCLUSION: Anti-HLA antibodies can be detected well after transplantectomy. Even if the kidney allograft had been transplanted for only a short time, when the intensity of immunosuppression was the highest, many patients developed anti-HLA antibodies. The patients who continued with immunosuppression after transplantectomy did not develop anti-HLA antibodies. PMID- 29579849 TI - Local Variation in Inclusion on Kidney Transplant Waiting Lists: Analysis in the Reference Area of a Kidney Transplant Center. AB - BACKGROUND: Access for end-stage renal disease (ESRD) patients to the renal transplant (RT) waiting list can vary depending on the criteria used and how they are applied in each dialysis unit. METHODS: This study was performed in the reference area (2.5 million inhabitants) of a transplant center. Data were from a regional registry (Information System of the Autonomous Coordination of Transplants in Andalusia) of total dialysis patients. Patients were grouped according to transplant status as: effective waiting list (WL); never recorded or excluded (E); incomplete immunologic study or discharge data (IIS); temporary contraindication (TC); or active (A). RESULTS: There were 1424 dialysis patients. Of these, 58% were E, 18% were IIS, 14% were TC, and 10% were A. Significant differences were detected for proportion of patients listed as active status (A) in 3 hospital dialysis units (2.9%-13.4%) and 12 hemodialysis centers (4.2% 29.2%); proportion of IIS cases in the hospitals (0%-57%) and dialysis centers (0%-58%); and in proportion of TC cases in the hospitals (19%-50%) and dialysis centers (2.5%-19.3%). The mean age of patients varied significantly between IIS, TC, and A groups (60.3, 54.8, and 52.3 years old, respectively, P < .001). Accentuated differences between the 2 provinces included in the sector were verified. There are notable differences in inclusion of pre-dialysis patients between hospital units. CONCLUSION: We detected considerable variability between hospital units and non-hospital dialysis centers in relation to inclusion on the active transplant waiting list and the proportion of patients with IIS or TC status. It is essential to implement a more homogeneous system for case selection through a specific intervention program from the reference center. PMID- 29579850 TI - Reasons for Noninclusion on the Kidney Transplant Waiting List: Analysis in a Set of Hemodialysis Centers. AB - INTRODUCTION: End-stage renal disease patients' access to the renal transplant (RT) waiting list (WL) depends on general criteria and their specific application in the different treatment units. METHODS: Study in nonhospital hemodialysis centers (n = 9), dependent on an adult RT center. Cases included 228 patients considered to have nonactive status on the WL due to incomplete immunologic data (no blood group or HLA typing) or temporary contraindication from an incomplete pretransplant study (nonimmunologic) or comorbidity. Each individual situation was studied by reviewing the center's clinical history with the nephrologist in charge. RESULTS: Three situations were classified three groups. (1) Patients in this group had incomplete basic study (65 patients, 28.5%) pending cardiologic evaluation in 34%; urologic evaluation, 26%; both 18%; others, 9%; study not initiated, 12%. (2) Patients in this group had pre-existing or onset comorbidities (117 patients, 51.3%) pending studies or confirmed resolution: obesity, 30%; cancer, 17%; cardiovascular disease, 14%; digestive pathology, 10%; infection, 9%; neuropsychiatric disorders, 7%; multiple, 13%. (3) Patients in this group had other situations contraindicating RT (46 patients, 20.2%): poor therapeutic adherence, 30%; negative will of the patient, 26%; social issues, 9%; excluded by the center (not reported), 35%. CONCLUSIONS: We detected a high incidence of cases pending basic tests for inclusion on the WL. Obesity can be highlighted as the most frequent cause for noninclusion. Further support and coordination is required with referral hospital centers to increase and refine the RT WL. PMID- 29579851 TI - CXCR3+ Monocytes Increase Significantly in Graft Blood Compared to Peripheral Blood in Patients With Stable Kidney Graft Function. AB - INTRODUCTION: We have recently reported that some lymphocyte populations do not maintain the same proportion in kidney graft blood as in peripheral blood, despite a stable function of the transplanted kidney. These results suggest that a comparative study between leukocyte cells from graft blood and those obtained from peripheral blood could provide information about the inflammatory state of the transplanted organ. In this work we selected the population of CD4+ lymphocytes and monocytes expressing CXCR3 to test this hypothesis. MATERIAL AND METHODS: The study was performed by flow cytometry during month 3, 6, and 12 after transplantation in 58 patients who received an isolated kidney transplant and the same immunosuppressive regimen. The peripheral blood sample was obtained by venipuncture and the graft blood by fine needle aspiration. RESULTS: We found a significant percentage decrease in CXCR3+ monocytes throughout the first year of transplantation in peripheral blood (15.9 +/- 20.7 vs. 12.6 +/- 12.4 vs. 6.3 +/- 9.0, at 3, 6, and 12 months, respectively; P = .001), whereas the percentage of CXCR3+ monocytes in graft blood did not change over this period. This situation resulted in a significant percentage difference between the CXCR3+ monocytes from the graft blood and those from the peripheral blood at the sixth (15.8 +/- 8.1 vs. 12.6 +/- 12.4, respectively; P = .008) and 12th months (12.9 +/ 8.1 vs. 6.3 +/- 9.0, respectively; P < .001). CONCLUSIONS: Therefore, we can conclude that the significant percentage increase of CXCR3+ monocytes in graft blood with respect to peripheral blood suggests the presence of inflammatory activity despite renal function being stable during the second half of the first year post-transplantation. PMID- 29579852 TI - 24-Hour Proteinuria Versus Spot Protein-Creatinine Ratio for Kidney Transplant Management in Clinical Practice. AB - BACKGROUND: 24-hour proteinuria (24h-P) has been the most widespread test for clinical follow-up of proteinuria after kidney transplantation (KT), but urine collection is often not properly collected. Spot protein-creatinine ratio (P/Cr) has become the alternative to 24h-P for proteinuria evaluation in many KT units. However, its reliability, equivalence to 24h-P, and prognostic value regarding allograft outcome remain unknown. Therefore, the aim of this study was to evaluate the correlation and agreement between both methods for assessing proteinuria and to analyze which of them is a better predictor of graft survival. METHODS: We collected proteinuria measurements from KT patients in our center. 24h-P was adjusted for body surface area. Pearson correlation test and the Bland Altman method were used to analyze correlation and agreement. Survival analysis was performed with the use of the Kaplan-Meier method and multivariate Cox proportional hazard model. RESULTS: A total of 8,549 urine samples were analyzed from 472 patients in whom 24h-P and P/Cr were simultaneously measured. A significant correlation was observed between 24h-P and P/Cr (r = .76; P < .001); however, the agreement between methods showed that P/Cr overestimated proteinuria compared with 24h-P, particularly when the latter was >1 g/24 h. The Cox regression multivariate model showed an increased risk of graft loss associated with proteinuria when assessed by either 24h-P (hazard ratio [HR] 6.53, 95% confidence interval [CI] 2.49-17.1) or P/Cr (HR 3.34, 95% CI 1.04-10.7). CONCLUSIONS: P/Cr is an method interchangeable with 24h-P for detecting proteinuria after KT. When proteinuria increases, the P/Cr overestimates 24h-P, even though it also has a significant and similar prognostic value for predicting graft survival. PMID- 29579853 TI - Survival and Evolution of Renal Function in Kidney Transplant Recipients From Type II Asystolic Donations: A Single-center Experience. AB - BACKGROUND: In recent years, stagnation in the number of kidneys from after brain dead donors (DBD) has stimulated the use of non-heart beating donors (NHBDs). Herein we present our 5-year experience with type II Maastricht NHBDs in renal transplantation. METHODS: All patients (n = 50) in this study received type II Maastricht NHBD kidneys (March 2012 to February 2017), with a median follow-up of 33 months. RESULTS: Mean donor age was 39 +/- 12 years, mean creatinine 1.24 +/- 0.2 mg/dL, and the most frequently observed blood group (donors and recipients) was type A (64%). Recipients were slightly younger (51 +/- 11 years old), with mean time on dialysis of 30 +/- 24 months. Almost all were primary transplants. Pre-transplant panel-reactive antibodies (PRA) were <25%; initial immunosuppression was thymoglobulin, corticosteroids, mycophenolate mofetil, and delayed introduction of tacrolimus. Six percent were nonfunctioning kidneys; 79.6% presented with delayed renal function (mean duration 14 +/- 9 days). Acute rejection was seen in 6% of patients. Mean creatinine at month 3 was 1.7 +/- 0.8 mg/dL, and 1.5 +/- 0.8 mg/dL in the first year. The last available mean creatinine was 1.54 +/- 0.7 mg/dL. Proteinuria in the third month, first year, and third year was 0.70, 0.41, and 0.26 g/d, respectively. Recipient survival at the first, third, and fifth year was 100%, 100%, and 86%, and when graft-censored for death was 94%, 91%, and 91%, respectively. The incidence of acute rejection during first year was 6%, and 2% in the second year. Exitus incidence was 4% and cytomegalovirus infection was 21.3%. BK viremia between 1000 and 10,000 copies/mL was seen in 4.3%, and reached >10,000 copies/mL in 2.1%. CONCLUSIONS: Type II NHBD has shown limited frequency of nonfunctioning kidney and high functional delay. The results in survival and renal function are very acceptable, comparable with levels seen in donation after brain death. PMID- 29579854 TI - Influence of Proportion of Normal Saline Administered in the Perioperative Period of Renal Transplantation on Kalemia Levels. AB - BACKGROUND: The hyperchloremic metabolic acidosis triggered by the infusion of normal saline (NS) significantly increases the level of extracellular potassium. In this study we assessed the influence of proportion of NS administered in the perioperative period of renal transplantation on potassium levels in usual clinical practice. METHODS: This study was a retrospective cohort analysis of patients undergoing renal transplantation during a 24-month period (2015-2016). To determine the influence of NS on K+ levels, simple linear regression and multiple linear regression analyses were performed, adjusted for the total volume of fluids administered, establishing the difference in serum K+ levels for each 20% increase in the proportion of NS. RESULTS: As the proportion of NS administered increased, K+ levels at 24 hours were significantly increased (P = .026) (0.69 mEq/L K+ increase per 20% increase in NS ratio). Mean K+ values at 24 hours (adjusted for total volume of fluids administered) ranged from 4.17 mEq/L (95% confidence interval [CI] 3.7-4.56) in patients who did not receive NS to 4.85 mEq/L (95% CI 4.56-5.15) in those administered exclusively NS. CONCLUSION: The risk of developing hyperkalemia in patients who receive a balanced solution with potassium in its formulation compared with NS in the perioperative period of renal transplantation is not increased, but the volume of NS administered is significantly associated with increases in K+ levels at 24 hours. PMID- 29579855 TI - Renal Transplant Immunosuppression in Patients With Hemolytic Uremic Syndrome: Four Case Reports. AB - A high rate of recurrence has been described in atypical hemolytic uremic syndrome renal transplant recipients, favored by certain immunosuppressant drugs that can induce complement activation. We present four case series in which three patients were diagnosed pretransplantation and a fourth who had onset in the very early post-transplantation period. The patients received different immunosuppression schedules, and all had improvement after more than 2-years. We suggest the need to stratify the risk of atypical hemolytic uremic syndrome recurrence using genetic studies and the available drugs as the main factors that allow graft survival improvement today. PMID- 29579856 TI - Resistant Cytomegalovirus Infection After Renal Transplantation: Literature Review. AB - BACKGROUND: Resistant cytomegalovirus (R-CMV) is an emerging problem in the renal transplantation population. The most frequent CMVs are high-resistance mutations (UL97 gene). METHODS: We describe our experience in management of R-CMV after renal transplant at our center (2012-2016). RESULTS: We encountered 3 cases of R CMV infection after renal transplant (all primary infections). All 3 patients received induction therapy with corticosteroids, tacrolimus, and mycophenolate mofetil. The first patient (basiliximab induction, preemptive CMV) developed CMV replication on day +53, which responded poorly both to standard-dose valganciclovir (vGCV) and high-dose ganciclovir (GCV) (creatinine clearance [CrCl] >70 mL/min; vGCV 900 mg twice daily for 50 days and GCV 7.5 mg/kg twice daily for 8 days). Hematologic toxicity occurred. The R-CMV test was positive and foscarnet (FOS) was initiated (90 mg/kg twice daily for 21 days). The second patient presented CMV infection (day +30, thymoglobulin induction, CMV prophylaxis), which was not controlled with the high dose (CrCl 23 mL/min; GCV 3.5 mg/kg twice daily and vGCV 900 mg twice daily), resulting in severe neutropenia. R-CMV was detected and FOS initiated (FOS 50 mg/kg twice daily for 7 days and 50 mg/kg every 2 days for 13 days). The third patient's infection occurred on day +22 (basiliximab induction, preemptive CMV). Standard-dose vGCV was uneffective (CrCl >70 mL/min, vGCV 900 mg twice daily) and it did not respond to the high dose (GCV 7.5 mg/kg twice daily and vGCV 2700 mg/d). Moderate hematologic toxicity occurred. R-CMV was diagnosed and FOS treatment begun (FOS 70 mg/kg per day for 2 weeks). CONCLUSIONS: Resistant CMV infection may be severe due to viral infection and side effects of high-dose antiviral treatment. We presented 3 cases requiring the use of FOS in the absence of response or toxic effects from the usual treatment, with an optimal sustained response (temporary in case 2) and without serious side effects. PMID- 29579857 TI - Cytomegalovirus Infection Monitoring Based on Interferon Gamma Release Assay in Kidney Transplantation. AB - BACKGROUND: Cytomegalovirus (CMV) is the most common viral infection after kidney transplantation and is associated with significant morbidity and mortality. Recent studies showed that CMV-specific CD8+ T cells play the crucial role in protection against CMV. The Quantiferon-CMV (QF-CMV) is an interferon gamma (IFN gamma) release assay (IGRA test) that measures the IFN-gamma response to a range of T-cell epitopes of CMV. In the present study, we analyzed the clinical utility of QF-CMV assay to predict CMV infection in kidney transplant recipients and evaluated if reactive result in QF-CMV test could be predictor of the duration of treatment. METHODS: We studied 75 renal transplant recipients who had IGRA testing just before transplantation. The donor and recipient variables were reported from the clinical history. The variables related to transplantation were collected from transplantation process data and included CMV infection or disease, CMV treatment, and immunosuppressive treatment. Laboratory variables were C3-C4 complement fractions and DNA quantification of CMV. RESULTS: Fifty percent of patients had CMV infection, and 35.9% had CMV disease. The time of negativization of CMV DNA was 56.61 +/- 23.5 days. Univariate analysis related to CMV infection only showed a statistically significant relation with thymoglobulin treatment (P = .001). Statistically significant variables in relation with CMV infection incidence were donor serology (P = .044) and thymoglobulin treatment (P = .004). The probability of CMV infection was lower with positive IGRA assay (P = .025). CONCLUSION: We found that IFN-gamma response measured by QF-MV is a protective factor against CMV infection in post-transplantation kidney recipients. PMID- 29579858 TI - Visceral Leishmaniasis in Renal Transplant Recipients: Report of 2 Cases. AB - Visceral leishmaniasis is a disease caused by the protozoan Leishmania and is transmitted by Lutzomyia longipalpis (sand fly). It is an endemic parasitic infection in numerous areas around the Mediterranean basin. Though immunocompetent patients may not develop the disease, in transplant recipients the use of corticoids and intensified immunosuppressants to prevent graft rejection may accelerate the disease, causing severe damage to the liver, spleen, and hematopoietic system. We report 2 cases of visceral leishmaniasis with an atypical presentation in transplant recipients. The first patient, who had a kidney transplant, was treated successfully with liposomal amphotericin B, and the second patient, a combined kidney-pancreas transplant recipient, suffered a relapse 3 years after treatment. Visceral leishmaniasis should be considered in the differential diagnosis of pancytopenia or unexplained fever occurring after organ transplantation in patients living in endemic areas or returning from endemic countries. PMID- 29579859 TI - Changes in Antihypertensive Therapy After Renal Transplantation. AB - INTRODUCTION: Post-transplant hypertension is extremely frequent, occurring in 60% to 90% of cases. It is involved in the pathogenesis of chronic graft dysfunction and patient survival. OBJECTIVES: We sought to describe changes in antihypertensive therapy after renal transplantation (RT) depending on the type of pretransplant renal replacement therapy (RRT), hemodialysis (HD) or peritoneal dialysis (PD). METHODS: We performed a retrospective cohort study of RT patients who were divided into 2 groups according to the type of pretransplant RRT (HD group: 69 patients; PD group: 38 patients). Patients with a diagnosis of nonessential hypertension etiology, diagnosis of renal artery stenosis of the graft, active urologic complications, and history of acute graft rejection were excluded. Variables related to chronic kidney disease and RT as well as antihypertensive therapy were studied. RESULTS: PD patients had reduced number of antihypertensive drugs at 1 month after RT (1.39 +/- 1.03) compared with pre-RT (2.16 +/- 1.30; P = .001), a trend that was maintained at 6 months (1.70 +/- 1.18; P = .06). In HD group, the number of antihypertensive drugs increased at 6 months after RT (1.59 +/- 1.17) compared with pretransplant (1.15 +/- 1.13; P = .027). The use of calcium channel blockers increased by 10.2% by 1 month (P = .071) and 9.2% (P = .036) by 6 months after RT. CONCLUSION: By 1 month after RT, antihypertensive therapy was reduced. Calcium channel blockers were the most common drug group, although it is usually necessary to use more than 1 drug. PMID- 29579860 TI - Initial Experience in the Use of Novel Auto-expandable Metal Ureteral Stent in the Treatment of Ureter Stenosis in Kidney Transplanted Patients. AB - INTRODUCTION: Ureter stenosis in renal transplantation patients is a relatively frequent complication that negatively conditions graft evolution. The use of ureteral stents is a valid treatment alternative to the use of double-J catheters in patients for whom surgery is not contemplated or after surgical recurrence. We present our initial experience with five patients treated using this technique. MATERIALS AND METHODS: We describe a total of five patients with ureteral stenosis after renal transplantation who were treated using ureteral stent model UVENTA (Taewoong Medical, Seoul, Korea) in our center. The median follow-up was 18 months (range, 4 to 38 months). We describe the clinical history of patients and previous treatments on ureteral stenosis. The technical procedure of placement is described. The clinical course is analyzed by measurement of renal function and imaging tests, as well as post-stent complications. Survival of the renal graft is evaluated. RESULTS: The procedure could be completed in all patients without complications. The technique was effective in all patients, with correction of creatinine value and hydronephrosis during the renal ultrasound test. One patient suffered a urinary tract infection episode associated with the use of the ureteral stent. One patient suffered the loss of the renal graft secondary to the development of cryoglobulins. One hundred percent of the ureteral stents are functioning as of the writing of this article. CONCLUSIONS: In renal transplantation patients with ureter stenosis, metallic stents are a useful technique with low morbidity and associated complications. PMID- 29579861 TI - Liver Transplantation in Patients With Hepatocellular Carcinoma Outside the Milan Criteria After Downstaging: Is It Worth It? AB - BACKGROUND: The outcome of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) is excellent if it is performed within the Milan criteria (ie, single tumor less than 5 cm or 3 tumors less than 3 cm each one and no macrovascular invasion). However, after a few studies, it has become possible to have a similar survival expanding those criteria. The aim of this study is to evaluate the survival of patients with advanced HCC who, after downstaging, did not met the Milan criteria although they were within the "up to seven" benchmark, and were transplanted at our center in the last 5 years. PATIENTS AND METHODS: This is a retrospective study of patients who underwent OLT for HCC in the last 5 years in our center exceeding Milan criteria despite remaining within the "up to seven" benchmark. An observational study of associated factors with overall survival based on patient characteristics after OLT was performed. For the statistical study, the statistical program SPSS v. 17.0 (Chicago, Illinois, United States) was used. RESULTS: We studied 95 patients who had been transplanted for HCC in this period, 11 of whom met the study requirements. There were 10 (91%) males and 1 female. The mean age of the patients was 54.73 +/- 8.75 years, with an average waiting list time of 279 days. Nine patients had a Child A status, with a mean Model for End-stage Liver Disease score of 9.64 (range, 6 to 16). The most frequent etiology of cirrhosis was hepatitis C virus infection in 6 patients (50%) followed by hepatitis B virus infection and ethanolic and cryptogenic cirrhosis. Ten patients (91%) had at least one pretransplantation transarterial chemoembolization. The survival of patients after 1 year was 75%, whereas after 4 years that rate decreases to 25%. At this time, we do not have any patients with a 5-year survival rate. The longest survival rate is 55 months. CONCLUSIONS: Although the expanded indication of transplantation in HCC raises controversies, especially after downstaging, it is possible to provide acceptable survival rates for patients within the expanded criteria of "up to seven" after locoregional therapies. The performance of a liver transplant in the patient profile shown in this article should also be evaluated from the perspective of the relative lack of organs for transplantation. PMID- 29579862 TI - Liver Transplantation in Recipients With High Model for End-stage Liver Disease Score. AB - OBJECTIVES: The score in the Model of End-stage Liver Disease, or MELD, is a good indicator of the survival in patients on the liver transplant waiting list. In this study, an analysis is performed on the benefits of liver transplant on those patients with a very high MELD score and who thus start from a very severe baseline state that could affect the surgical outcome. MATERIALS AND METHODS: A prospective study was conducted on a cohort of 331 patients that received a liver transplant between 2002 and 2014. The patients were divided into 2 groups according to the MELD score (<28 vs >=28), and differences in age, postoperative complications, stay in the intensive care unit (ICU), hospital stay, and survival were compared. RESULTS: Of the total of 331 patients, 21 (6.3%) had a MELD score >= 28. The mean age of the group with MELD score >= 28 was lower than the age in the group with MEDL score < 28 (42.5 vs 53.7 years; P < .0001). No significant increase was observed in postoperative complications. Although there were also no differences in survival, the group with MELD score >= 28 did have a longer stay in ICU and a longer hospital stay (with a mean of 6.7 days in ICU and 41.5 days admission vs 4.1 and 26.9, respectively). CONCLUSIONS: A very high MELD score is associated with a longer stay in ICU and more days of hospital admission, although no differences were observed in postoperative complications or survival. Therefore, there does not seem to be any contraindication in transplantation in this group of patients. PMID- 29579863 TI - Analysis of Indications and Results in Liver Retransplantation: Is Late Retransplantation Worthwhile? AB - BACKGROUND: Liver retransplantation (LrT) is the only therapeutic option for irreversible hepatic graft failure. Despite various improvements, its technical complexity entails a greater morbidity in the short and long term. The main goal of the study was to analyze the activity of LrT at our center, as well as its indications, timing, postoperative evolution, and the long-term survival of patients. METHODS: We designed a descriptive study of a cohort of patients who underwent LrT in a Spanish Hepatic Transplant Unit, between April 1, 2002 and December 31, 2015. RESULTS: A total of 366 primary orthotopic liver transplantations were performed, 20 of which were LrTs, resulting in a 5.5% retransplantation rate. The most frequent indication for LrT was hepatic artery thrombosis (HAT) (35%). Twenty-five percent of the LrTs were early retransplantations and 75% were late retransplantations. After LrT, 35% of the grafts showed liver dysfunction. The overall mortality rate was 45%: in early LrT this was 25% and in late LrT it was 46.7%. Graft actuarial survival at 1 month post-LrT was 75% and at 5 years it was 63.6%. The overall actuarial survival after LrT at month 1, year 1, year 3, and year 5 was 80%, 69.6%, 58.9%, and 50.5%, respectively. In the late LrT group, the results proved less favorable, so it is necessary to define the minimum acceptable result before proceeding to a second graft. CONCLUSION: Our LrT rate was lower than that reported by other groups in our country. The actuarial survival rates for graft and patient are comparable to those obtained by other groups. PMID- 29579864 TI - Outcomes of Liver Transplantation Using Older Donors After Circulatory Death and the Super-Rapid Technique: 14 Cases. AB - INTRODUCTION: Donation after circulatory death (DCD) has increased in the last decade, although a slight increase in surgical complications has been reported in liver transplantation (LT). Therefore, DCD is not recommended with donors aged 60 years or more because it entails an added risk. However, donation after brain death (DBD)-LT with donors aged 70 years or more shows acceptable results. OBJECTIVE: The objective was to analyze the characteristics and complications of DCD-LT with donors aged 70 years or more (DCD-70). MATERIALS AND METHODS: We included 14 DCD-70-LT and compared them with a control group of 28 DBD-LT aged 70 years or more. STATISTICAL ANALYSIS: A descriptive analysis, Mann-Whitney U test, and Pearson chi-square or Fisher test were performed when appropriate. RESULTS: Significant differences were found in aminotransferase peak at 24 hours, with an increase in the DCD-70 group (aspartate aminotransferease [AST] 1038 vs 507, P = .013; alanine aminotransferase [ALT] 750 vs 399, P = .014). The cold ischemia time was lower in DCD-70 although without significant differences (4.8 vs 6.7 hours). Biliary complications (28.6% vs 31.7%) and vascular complications (7.1% vs 7.1%) were similar. A single transplant with DCD-70 required a retransplantation due to arterial thrombosis. Mortality was the same in both cases (14.3%). CONCLUSION: LT results with DCD-70 are similar to those of DBD-70, so the age criteria could also be extended in this type of donation. PMID- 29579865 TI - Analysis of the Predictive Ability for Graft Loss and Mortality of Two Criteria for Early Allograft Dysfunction After Liver Transplantation. AB - INTRODUCTION: The current imbalance between available donors and potential recipients for orthotopic liver transplantation (OLT) has led to a liberalization of organ acceptance criteria, increasing the risk of post-transplant complications such as early allograft dysfunction (EAD). Consequently, we need accurate criteria to detect patients with early poor graft function to guide the strategies of management. We evaluated the usefulness of two frequently used criteria: the definition from Olthoff et al and the Model for Early Allograft Function (MEAF) scoring. PATIENTS AND METHODS: Unicentric cohort study of patients undergoing OLT between January 1, 2010, and November 20, 2016. We performed a univariate study to detect donor, recipient, and transplant factors favoring EAD, defined both by Olthoff criteria and a MEAF score higher than 7. Finally, we developed a comparative survival analysis for cases having or not EAD. RESULTS: In all, 201 transplants met inclusion criteria. According to the stated cutoff for MEAF score, the frequency of EAD was 9.3%, with a significant association to low recipient body mass index and prolonged total graft ischemia time, resulting in lower patient 3-month postoperative survival. According to Olthoff criteria, EAD incidence was 22.1% and was associated with younger donor and recipient ages and higher Model for End-stage Liver Disease and Child-Pugh recipient scores. Its development resulted in lower graft and recipient survival at 3 months after OLT. CONCLUSION: MEAF score and Olthoff criteria are useful tools for detection of EAD. The latter could select more appropriately patients at risk, but its calculation cannot be done until the seventh day after OLT, unlike MEAF score, available on third day. PMID- 29579866 TI - How Thinking About the Donor Influences Post-traumatic Growth in Liver Transplant Recipients. AB - OBJECTIVE: The aim of this work was to find out whether thinking frequently about the donor influences post-traumatic growth of liver transplant recipients. METHODS: The sample of 240 patients selected was made up of 185 men and 55 women with an overall mean age of 60.21 (SD 9.3) years. All of them had received liver transplants from cadaver donors. Transplant recipients were asked whether they thought frequently about the donor (yes or no) and filled out the Post-traumatic Growth Inventory. The t test for unpaired samples was applied to analyze how thinking frequently about the donor or not influenced post-traumatic growth. We also calculated the effect sizes by means of Cohen d or Cohen w depending on the nature of the variables analyzed (quantitative or qualitative). RESULTS: The liver transplant recipients who thought frequently about the donor, compared with those who did not, had higher total scores on post-traumatic growth (P = .000; d = 0.57; medium effect size). Furthermore, considering the effect sizes, the differences between the subgroups were more relevant on the following subscales: new possibilities (P = .000; d = 0.53; medium effect size), appreciation of life (P = .000; d = 0.60; medium effect size), and spiritual change (P = .000; d = 0.54; medium effect size). CONCLUSIONS: Patients who think frequently about the donor have more post-traumatic growth than those who do not. PMID- 29579867 TI - Multicentric Study of the Andalusian Experience in Polycystic Liver Disease as Indication for Liver Transplantation. AB - BACKGROUND: The purpose of this study was to determine the morbidity and survival in patients with polycystic liver disease (PLD) undergoing liver transplantation (LT) in 4 Spanish hospitals. METHODS: A multicentric retrospective study using a prospective database was designed including 19 LTs after PLD diagnosis performed from January 1, 1990, to December 31, 2016. Pediatric patients were excluded from the analysis. RESULTS: Of the included patients, 63.2% were female, the overall average age was 52.16 +/- 11.276 years, median time on the waiting list was 394 days (interquartile range [IQR], 96.25-464.50) and most of them were classified with Model for End-Stage Liver Disease scores of <=17. Eleven patients received isolated LT, 1 patient had a previous kidney transplantation (KT), and 7 patients received combined liver-kidney transplantation, 4 of them with a previous nephrectomy. Complications include hepatopulmonary syndrome in 10.5%, paralytic ileus in 10.5%, transient renal dysfunction in 10.5%, and hepatorenal syndrome in 5.3%. The most common surgical complication was bleeding (15.8%). Three patients presented graft rejection, which was treated by means of immunosuppressive optimization (15.8%), with corticosteroid addition needed in 1 of them. Thrombosis of the hepatic artery occurred in 3 patients, requiring retransplantation in 2 of them. Most of the patients had improved renal function after the procedure. The mortality rate was 15.8%, related to tumors or sepsis, with an estimated 86% 5-year graft survival. CONCLUSIONS: PLD as indication of LT presents a low complications rate and better graft survival and renal function, especially when KT is associated with LT. PMID- 29579868 TI - Results of 15-Year Experience in Liver Transplant for Hepatocellular Carcinoma. AB - BACKGROUND: Liver transplant (LT) supposes a curative option for those patients with hepatocellular carcinoma (HCC) meeting the Milan criteria. Adjuvant therapies, such as transarterial chemoembolization (TACE), can prevent tumor progression. Our aim was to analyze the outcomes of patients who have been transplanted at our center and to assess the effectiveness of TACE in patients on the waiting list for LT. METHODS: Eighty-nine patients who underwent LT for HCC at our hospital from 2002 to 2017 were included. Data on the number and size of nodules on image testing and explant, frequency of TACE and tumor response, mortality, and tumor recurrence were collected. TACE was indicated when waiting time was estimated to exceed 6 months in patients with well-preserved liver function (Child-Pugh score A-B7). Magnetic resonance imaging (MRI) was performed after TACE. RESULTS: We found a single nodule in 64% of patients and multiple nodules in 36% of patients. Mean size of nodule on image testing was 38.29 mm, similar to the mean size at explant (32.65 mm). TACE was performed in 66 patients (74.2%). Ten patients did not meet the Milan criteria at explant, 6 of whom died, and 10 patients had tumor recurrence at mean of 22.6 months. Overall mortality was 44.9%, but only 10 patients died because of tumor recurrence. CONCLUSIONS: TACE responses were achieved in one third of patients and there was an 11.2% recurrence rate for HCC. Mortality in our experience has been related to exceeding the Milan criteria at explant. PMID- 29579869 TI - Efficacy and Safety of Anti-TNF-alpha Agents in Inflammatory Bowel Disease After Liver Transplant: A Case Series. AB - BACKGROUND: Ulcerative colitis (UC) and Crohn disease (CD) can appear de novo or worsen after liver transplant. Our aim was to assess the efficacy and safety of anti-tumor necrosis-alpha (anti-TNF-alpha) agents after transplantation. METHODS: We reviewed the clinical database of our center searching for all liver transplant patients with inflammatory bowel disease who were treated with anti TNF-alpha agents between 1997 and 2017. Clinical response was assessed from clinical activity indices 12 weeks after starting treatment. The median age of the 6 patients (3 women) was 37 years. Four patients were diagnosed before transplantation (2 UC and 2 CD), and in the other 2 the disease appeared de novo (1 UC and 1 CD). The indications for transplant were primary sclerosing cholangitis (n = 3), cryptogenic cirrhosis (n = 2), and hepatitis C virus cirrhosis (n = 1). RESULTS: Clinical response was seen in 3 of the 6 patients and, in the 3 cases for whom endoscopic data were available, no mucous healing was seen. The only adverse effects noted over a mean follow-up of 15 months were 1 cytomegalovirus infection and 1 severe infusion reaction to infliximab. No patients had recurrence of primary sclerosing cholangitis in the graft, and none of the patients died. CONCLUSION: Use of an anti-TNF-alpha agent in a liver transplant patient with inflammatory bowel disease may be an effective option, with an acceptable risk-benefit ratio. Further studies are required to confirm their use in this context. PMID- 29579870 TI - Matrix Metalloproteinase 1 as a Novel Biomarker for Monitoring Hepatocellular Carcinoma in Liver Transplant Patients. AB - INTRODUCTION: Orthotopic liver transplantation (LT) is considered to be one of the few curative treatments available for early stages of hepatocellular carcinoma (HCC). Alfa-fetoprotein (AFP) is the most-used biomarker for HCC despite low sensitivity and specificity. Matrix metalloproteinase 1 (MMP-1) has been considered to be involved in the process of vascular invasion of the malignant cells. The objective of this study was to assess the use of MMP-1 for the management of HCC patients for LT. METHODS: Levels in serum of MMP-1 (ng/mL) and AFP (ng/mL) were assessed in 20 HCC patients (Milan criteria) before and 1, 6, and 12 months after LT. RESULTS: There was a strong significant correlation between levels of MMP-1 and levels of AFP (rho = .954; P <= .05). There were statistical differences in the levels of MMP-1 and APF between the pre transplantation and post-transplantation groups (1 and 12 months). Increments of both markers 6 months after LT compared with the levels 1 month after LT were detected in 4 of the 20 HCC patients. The detection of recurrence by means of imaging was coincident with the increment of both markers 6 months after LT in 3 of those 4 patients. CONCLUSIONS: After 12 months of follow-up, levels of MMP-1 were comparable to AFP levels after LT. Levels of both markers increase 6 months after LT in patients showing recurrence, indicating discriminatory power to predict relapse and thus serving as valuable markers for HCC monitoring. MMP-1 could be useful in the management of HCC after LT. PMID- 29579871 TI - Analysis of Ischemic Cholangiopathy After Treatment of Arterial Thrombosis in Liver Transplantation in Our Series. AB - Liver transplantation offers patients with terminal liver disease an effective treatment accompanied by excellent quality of life, but it also has complications, such as hepatic artery thrombosis and development of ischemic cholangiopathy, described in 3%-17% of patients. It is a very important cause of morbidity and mortality. The objective of this report was to analyze the efficacy of the treatment they received in relation to the development of ischemic cholangiopathy and a comparative survival analysis and to propose prophylactic measures for high-risk patients. PMID- 29579872 TI - Therapy With Direct-Acting Antiviral Agents for Hepatitis C in Liver Transplant Recipients. AB - BACKGROUND: Recurrent infection with the hepatitis C virus (HCV) after liver transplantation (LT) is associated with decreased graft and patient survival. Direct-acting antiviral (DAA) therapies have changed the landscape of HCV due to their excellent safety profile and cure rates. Our aim was to evaluate the efficacy and tolerability of antiviral therapy in recurrent HCV after LT with DAA therapy. METHODS: Our retrospective analysis included 46 LT recipients with HCV recurrence. Patients received therapy with DAA therapy between November 2014 and May 2016. Stage of fibrosis was documented by transient elastography (FibroScan). RESULTS: Thirty-three of the patients were men (71.7%), with a mean age of 59.6 years. Most patients were infected with HCV genotype 1 (71.7%) (1a = 7, 1b = 26) or genotype 3 (19.6%). Cirrhosis was present in 10 (21.7%). The most frequent immunosuppression regimen was tacrolimus + mycophenolate mofetil (MMF) (41.3%). Most patients received sofosbuvir + simeprevir (SOF+SMV) (n = 13, 28.3%) and sofosbuvir + daclatasvir (SOF+DCV) (n = 15, 32.6%). A virologic response at posttreatment week 12 was detected in 93.8% of the patients. Two patients failed treatment (1 had resistance-associated variants [RAVs] Y93H in NS5A). Three patients died due to chronic rejection, acute arterial thrombosis, and spontaneous bacterial peritonitis. Adverse events were observed in 23 patients (50%). The most common events were asthenia in 17 (37%) and headache in 6 (13%) patients. One patient discontinued treatment due to serious adverse events attributable to the drug's interaction with tacrolimus. CONCLUSIONS: DAAs are safe and effective for use in treating HCV recurrence after LT, with results similar to those seen in the general population, including patients with cirrhosis. PMID- 29579873 TI - Long-term Survival and Evolution of the Kidney Function for Liver Transplant Patients Who Required Postoperative Dialysis. AB - Patients who underwent orthotopic liver transplantation (OLT) frequently develop chronic kidney disease, with those who present postoperative acute kidney failure and require renal replacement therapy (RRT) at higher risk. The objective of the study was to assess the kidney function and long-term survival of patients who underwent OLT and required RRT during or in the immediate postoperative period. Medical records of OLT and postoperative RRT patients with over 6-month survival were reviewed between January 1, 2005, and December 31, 2015. A variance analysis was carried out for repeated measurements to compare the estimate glomerular filtration rate (eGFR) baseline with the different periods (statistical significance level P < .05). Kaplan-Meier estimator was used to estimate the survival rate. Of 539 patients, 20 (3.7%) met the selection criteria. The basal eGFR at 6 months and 1, 3, 5, and 7 years was 93.41 +/- 25, 78.28 +/- 33, 73.06 +/- 29, 65.96 +/- 19, 79.81 +/- 28, and 59.06 +/- 24 mL/min/1.73 m2, respectively. The comparison of the eGFR baseline within the different periods was statistically significant at 1 year and at 3 years. Four patients died, 3 of them due to sepsis and 1 due to recurrence of hepatitis C virus infection. The average survival was 28 months. The probability of surviving at 1 year was 100%, at 3 years was 84.21% (95% confidence interval: 58.65-94.62), and at 5 and 10 years was 78.6% (95% confidence interval: 52.49-91.39). In conclusion, we have found a progressive worsening of the kidney function in the long term in patients who required postoperative dialysis. However, actuarial survival of these patients was very successful. PMID- 29579874 TI - Cold Ischemia Time as a Factor in Post-transplantation Complications for Orthotopic Hepatic Transplantation. AB - OBJECTIVE: This study aims to compare a shorter cold ischemia time with the present one in relation to the complications developed in liver transplantations. DESIGN: This is a retrospective, observational study of orthotopic liver transplantations performed with grafts from brain-dead donors during 12 months at a University Hospital (Seville). We compare incidence rates of complications (reperfusion syndrome, arterial and biliary complications, and prostaglandin requirements) between two groups according to cold ischemia times (group A < 6 hours; group B > 6 hours). RESULTS: Sixty cases were included. There were more males in both groups as donors (55.5%) and recipients (75%). The median age was higher in group B in two cases. The Model for End-stage Liver Disease score was higher in patients with a shorter cold ischemia time, with a median of 20 hours (range, 16 to 26.5 hours). We observed that reperfusion syndrome (3.4% vs. 13.3%; P = .353), vascular complications (6.9% vs. 24.1%; P = .144), biliary tract complications (13.8% vs. 20.7%; P = .730), and prostaglandin requirements (3.4% vs. 20.7%; P = .102) were more common in group B, although without reaching statistical significance. After uni- and multivariate analyses, cold ischemia time longer than 6 hours was the only risk factor to develop complications (odds ratio: 3.578; 95% confidence interval: 1.125 to 11.374, P = .031). CONCLUSION: According to the results of our analysis, cold ischemia times longer than 6 hours, as tends to be the usual procedure in most centers, imply higher rates of complications after liver transplantation. PMID- 29579875 TI - Donors Older Than 75 Years Do Not Influence the Appearance of Biliary Complications After Liver Transplantation. AB - BACKGROUND: In recent years, several studies have shown that the age of the donor may be related to an increase in the occurrence of biliary complications (BCs), which remain the main cause of morbidity after liver transplantation. This study analyzed the type and management of these BCs, the impact of BCs on graft and patient survival rates, and the influence of some characteristics of donors and recipients on BC appearance in patients transplanted with donors 75 years of age or older. PATIENTS AND METHODS: From 2003 to 2016, 100 liver transplantations with donors 75 years of age or older (15.6%) were performed in our hospital. The data were compared with a control group of 400 patients with younger donors (case control 1:4 per chronology). RESULTS: The BC rate in the group of patients transplanted with organs from elderly donors was 18%, compared to 21.5% in the control group. Specifically, in the immediate post-transplantation period, 14% of the elderly donor group and 13.8% of the control group presented some BCs, with no statistically significant differences in the incidence, type, and treatment of BCs between the two groups. The occurrence of BCs was not a factor associated with graft and patient survival rates. In the global population, donor death by cerebral vascular accident and male donors have influenced the occurrence of BCs. CONCLUSIONS: The advanced age of the donor has not influenced BC rates after transplantation. PMID- 29579876 TI - Orthotopic Liver Transplantation: Preliminary Analysis of Complications With Grafts From Elderly Donors. AB - OBJECTIVE: This study aims to determine if donor grafts of patients older than 65 years develop more post-transplantation complications than those of younger patients. DESIGN: This is a retrospective, observational study of liver transplant recipients during 12 months in Virgen del Rocio University Hospital. We compare incidence rates of reperfusion syndrome, acute kidney injury, and need for intra- and postoperative red blood cell transfusions in two donor age groups in which group A is <65 years old and group B is >=65 years old. RESULTS: Sixty cases were included. Reperfusion syndrome, acute kidney injury, and both intra- and postoperative red blood cell transfusion were more frequent in group A than group B (11.4% vs. 4%, P = .390; 44% vs. 32%, P = .423; 68.8% vs. 48%, P = .120; and 70.6% vs. 64%, P = .779, respectively). Six recipients (17.1%) died at 12 months from group A whereas there were no deaths register in group B during that time (P = .036). CONCLUSION: Our results showed that including elderly donors does not aggravate incidence of complications, emphasizing that advanced age should not be an exclusion criteria for liver transplantation. PMID- 29579877 TI - Family Caregivers of Liver Transplant Recipients: Coping Strategies Associated With Different Levels of Post-traumatic Growth. AB - OBJECTIVE: Analyze the influence of 2 variables (post-traumatic growth and time since liver transplantation) on coping strategies used by the transplant recipient's family members. METHODS: In all, 218 family members who were their main caregivers of liver transplant recipients were selected. They were evaluated using the Posttraumatic Growth Inventory and the Brief COPE. A 3 * 3 factorial analysis of variance was used to analyze the influence that post-traumatic growth level (low, medium, and high) and time since transplantation (<=3.5 years, >3.5 to <=9 years, and >9 years) exerted on caregiver coping strategies. RESULTS: No interactive effects between the two factors in the study were found. The only significant main effect was the influence of the post-traumatic growth factor on the following variables: instrumental support (P = .007), emotional support (P = .005), self-distraction (P = .006), positive reframing (P = .000), acceptance (P = .013), and religion (P = <.001). According to the most relevant effect sizes, low post-traumatic growth compared with medium growth was associated with less use of self-distraction (P = .006, d = -0.52, medium effect size), positive reframing (P = .001, d = -0.62, medium effect size), and religion (P = .000, d = 0.66, medium effect size), and in comparison with high growth, it was associated with less use of positive reframing (P = .002, d = -0.56, medium effect size) and religion (P = .000, d = 0.87, large effect size). CONCLUSION: Regardless of the time elapsed since the stressful life event (liver transplantation), family members with low post-traumatic growth usually use fewer coping strategies involving a positive, transcendent vision to deal with transplantation. PMID- 29579878 TI - Prognostic Value of Blood Panel Parameters in Patients With Dilated Cardiomyopathy and Advanced Heart Failure. AB - BACKGROUND: Patients with dilated cardiomyopathy (DCM) and left ventricular dysfunction have a varied clinical course, not only dependent on left ventricular ejection fraction (LVEF) and symptoms. Finding prognostic markers for stratification in these 2 conditions is a critical area of research. Our aim was determine the prognostic value of blood panel basic parameters. METHODS: We analyzed all patients with idiopathic or familial DCM and LVEF <30% coming to our heart failure unit for evaluation for non-urgent heart transplant during the period of 2009 to 2011. With 5 years of follow-up data, we could study the prognostic value of blood panel parameters. Moreover, we determined the combination of platelet count and neutrophil to lymphocyte ratio score from the BIOSTAT-CHF study. RESULTS: Eighty-seven patients were included in the study. After 5 years follow-up, 49 patients (57%) remain alive (group A) and 38 (43%) either died or needed a heart transplant. There were no differences between groups with regard to age or sex. Patients with good progress showed a lower red cell distribution width (RDW), a higher lymphocyte count, and a lower neutrophil/lymphocyte ratio in the initial blood panel. An RDW >=15% was associated with long-term mortality or heart transplant. CONCLUSION: A basic blood panel could be a useful tool in assessing patients with heart failure. Larger studies are necessary to confirm our findings. A multimarker strategy could also be useful for stratification of patients with advanced heart failure.

AB - The CentriMag (Levitronix LLC, Waltham, MA, USA) ventricular assist device is a centrifugal pump designed for short-term support in patients with cardiogenic shock. In patients with restrictive physiology, there is some concern about the use of these devices due a very small ventricular cavity. We review the evolution of a 32-year-old woman with restrictive cardiomyopathy, moderate pulmonary hypertension, and severe biventricular systo-diastolic dysfunction in whom a biventricular Centrimag device was implanted due to a progressive clinical worsening. PMID- 29579880 TI - Complex Congenital Heart Disease: Is Heart Transplantation an Option? AB - INTRODUCTION: Within the heart transplant (HT) population, few patients have complex congenital heart disease (CHD) underlying disease. Our objective is to assess the complications and follow-up of patients with CHD transplanted in our center (1991-present). MATERIAL AND METHODS: Retrospective analysis of patients older than 14 years old with CHD and HT. Clinical and surgical variables were analyzed. RESULTS: Ten patients (age 25 +/- 7 years old, 60% male) were analyzed, which represents 2.2% of the entire series of HT; 9 of the 10 patients were electively transplanted and 1 was under support with extracorporeal membrane oxygenation. Compared with the rest of the transplanted patients, patients with CHD had a lower median age (25 [25-36] vs 53 [15-69]; P < .009); more cardiac surgeries prior to HT (100% vs 14.4%; P < .001); a lower percentage of cardiovascular risk factors (CVRF; 0% vs 60%; P < .001). The left ventricle ejection fraction also showed statistically significant differences (33.5 [12-67] vs 20 [6-70]). CONCLUSIONS: Our patients with CHD and HT are younger and have less CVRF and more cardiac surgeries, which highlights that it is a subgroup with clear clinical differences in its comorbidity and pretransplantation assessment. They also require longer extracorporeal circulation time, more hours of intubation, and more days in the intensive care unit. Primary graft failure is more common in patients with CHD. Therefore, survival at 1-month follow-up is lower than the rest of the series and equalizes after the year of follow-up. This long-term survival reaffirms the possibility of HT in CHD despite the fact that its postoperative period is more difficult. PMID- 29579881 TI - Long-term Prognosis After Lung Transplantation: A Monocentric Study in 510 Patients. AB - INTRODUCTION: Lung transplantation is the final treatment option in patients with respiratory failure. Morbidity and mortality rates associated with the management of complications is high despite advances. Postoperative complications include acute transplant rejection, bronchiolitis obliterans, and infections. Because of that, the success of this treatment option depends on the correct choice of donor and candidates to receive a transplant. OBJECTIVE: This study aims to perform a survival analysis of transplanted patients in our center and determine predictive variables of mortality. PATIENTS AND METHODS: This study is a retrospective assessment of data collected from 510 patients at the Hospital University Reina Sofia from October 1993 to December 31, 2016. Patients who were retransplanted were excluded. We collected data regarding basal characteristics of the donors and candidates to receive a transplant. We analyzed the impact in terms of future survival of basal variables from donor and donor recipients. RESULTS: Five hundred ten patients were included (average age 44 +/- 17 years, 69% male), with a maximum follow-up period of 21.6 years (average follow-up 4.52 years, interquartile ratio: 0.13 to 6.97 years). Two hundred twenty-seven patients died (54.3% of the total amount). The influence of donor's basal characteristics on mortality was analyzed; moreover, the relationship between basal variables and survival were analyzed using univariate analysis. Available variables were analyzed through multivariate analysis. CONCLUSION: Lung transplantation is a treatment option with an acceptable risk of morbidity and mortality. Increased awareness of features of evolution could help to reduce postoperative complications. PMID- 29579882 TI - Left Single Lung Transplantation Through Left Anterolateral Thoracotomy With Longitudinal Partial Sternotomy (Hemiclamshell): An Innovative Surgical Resource. AB - INTRODUCTION: Pulmonary fibrosis (PF) is one of the main indications for lung transplantation among end-stage respiratory diseases. PF represents a surgical challenge due to the pulmonary retraction, reduction of pleural space, and limitation for access of the lung hilum by elevation, specifically on the left lung. Unilateral sternothoracotomy, or hemiclamshell (HCS) approach, is the anterolateral thoracotomy with longitudinal partial sternotomy with possibility of cervical extension. This was initially described as a surgical approach for resection of lung apex tumors and of the cervicothoracic region, excision of mediastinal and thoracic wall tumors, and as an urgent incision for the repair of mediastinal and cervicothoracic vascular lesions. HCS is not usually described for liver transplantation. CASE: A 62-year-old man who was a nonsmoker was diagnosed with idiopathic PF. After 3 years of medical management and follow-up, the patient was referred to us for a pretransplantation study. He presented with dyspnea grade III according to the Medical Research Council. In the radiograph of the chest and computed tomography of the thorax showed signs of pulmonary fibrosis predominantly left-lung associated with loss of volume and alteration of respiratory function tests. We performed left single lung transplantation through a left HCS approach. During implantation we converted the superior pulmonary vein into "neo-atrium" for the atrial anastomosis. The patient presented excellent evolution and was discharged from the hospital at 26 days. CONCLUSION: We present a case of left single lung transplantation by PF through an HCS approach as novel and effective resource for this type of procedure. PMID- 29579883 TI - What Is the Influence of Both Risk Donor and Risk Receiver on Simultaneous Pancreas-Kidney Transplantation? AB - INTRODUCTION: Some factors affect the pancreas of a marginal donor, and although their influence on graft survival has been determined, there is an increasing consensus to accept marginal organs in a controlled manner to increase the pool of organs. Certain factors related to the recipient have also been proposed as having negative influence on graft prognosis. The objective of this study was to analyze the influence of these factors on the results of our simultaneous pancreas-kidney (SPK) transplantation series. MATERIALS AND METHODS: Retrospective analysis of 126 SPK transplants. Donors and recipients were stratified in an optimal group (<2 expanded donor criteria) and a risk group (>=2 criteria). A pancreatic graft survival analysis was performed using a Kaplan Meier test and log-rank test. Prognostic variables on graft survival were studied by Cox regression. Postoperative complications (graded by Clavien classification) were compared by chi2 test or Fisher test. RESULTS: Median survival of pancreas was 66 months, with no significant difference between groups (P > .05). Multivariate analysis showed risk factors to be donor age, cold ischemia time, donor body mass index, receipt body mass index, and receipt panel-reactive antibody. CONCLUSIONS: In our series, the use of pancreatic grafts from donors with expanded criteria is safe and has increased the pool of grafts. Different variables, both donor and recipient, influence the survival of the pancreatic graft and should be taken into account in organ distribution systems. PMID- 29579884 TI - Prevalence and Survival of Cancer After Pancreas-Kidney Transplantation. AB - BACKGROUND: Malignancy is an important cause of mortality in solid organ transplantation. There have been few studies of de novo solid organ malignancy (NSOM) after pancreas-kidney transplantation (PKT). The aim of this study was analyze the prevalence of NSOM and transplant outcomes. METHODS: We studied the development of NSOM after PKT in our center from May 1990 to February 2017. We analyzed demographic characteristics, prevalence of cancer, and survival after cancer diagnosis. We excluded nonmelanoma skin cancer and patients with history of malignancy before transplantation. RESULTS: We included 194 patients who received 206 PKTs (184 simultaneous PKTs and 22 pancreas after kidney transplants) with triple immunosuppressive therapy and basiliximab in more than 95%. The mean age at transplantation was 39 +/- 7 years and 74% were male patients. Twelve patients developed malignancies (6.1%). Median time from transplant to NSOM was 6.6 (interquartile range [IQR] 0.2-11.7) years. The malignancies were 2 cecal appendix tumors, 2 hematologic tumors, 2 breast tumors, 1 melanoma, 1 native kidney tumor, 1 brain tumor, 1 bladder tumor, 1 prostate tumor, and 1 leiomyosarcoma. Thirty-five of the 194 patients of the whole cohort died throughout the follow-up, 4 of whom died after NSOM diagnosis (11.4%). Patient and grafts survivals were lower in recipients with tumor compared with recipients without tumor, but the difference was not statistically significant: renal graft survival was 80% vs 90% at 10 years (P = .86); and pancreatic graft survival was 45% vs 70% at 10 years (P = .15), respectively. The mean patient survival time from the diagnosis of cancer was 36.6 (IQR 18-54) months. Patient survival after NSOM diagnosis was 90% at 1 year and 50% at 5 years. CONCLUSION: The prevalence of NSOM in our PKT recipients is low, despite the scarce series of published data for comparison. Also hematologic tumors rate is very low, possibly influenced by age and type of induction. PMID- 29579885 TI - Intraoperative Heparinization During Simultaneous Pancreas-Kidney Transplantation: Is It Really Necessary? AB - INTRODUCTION: The use of intraoperative sodium heparin during simultaneous pancreas-kidney transplantation (SPKT) remains as a routine practice in some referral centers to minimize pancreatic graft thrombosis rate. One of its disadvantages is the theoretical increased risk of postoperative bleeding. In our center, we have abandoned its use since 2011. MATERIALS AND METHODS: We performed a retrospective analysis among 198 SPKTs performed in our center between the years 1989 and 2017. The variables of our study were vascular thrombosis of the pancreatic graft and hemoperitoneum and upper gastrointestinal bleeding in the mediate postoperative period (up to 2 months after the transplant). We compared these results between SPKT recipients who had undergone intraoperative heparinization (n = 157) and those who had not (n = 51). To avoid bias, a second comparison was performed using propensity score matching on the following characteristics: sex, recipient age, recipient body mass index, cold ischemia time, preoperative hemodialysis or peritoneal dialysis, time of diabetes, and Pancreas Donor Risk Index. Student t test or Mann-Whitney U test was used for intergroup comparisons of quantitative variables where appropriate, whereas chi2 or Fisher exact test was used to compare categorical data. RESULTS: No statistically significant differences were found when comparing the use of intraoperative heparin, even after the homogenization of both groups. CONCLUSIONS: In our experience, intraoperative heparinization during SPKT surgery was not useful because it did not significantly decrease the graft thrombosis rate, and its withdrawal did not enhance hemoperitoneum or upper gastrointestinal bleeding postoperative rates. PMID- 29579886 TI - Pancreas Donor Hypernatremia: Is it Really a Risk Factor for Simultaneous Pancreas-kidney Transplantation? AB - INTRODUCTION: Solid organ donor hypernatremia has been classically reported to be a risk factor for cell lysis and graft damage. National criteria for pancreatic donation consider severe hypernatremia (sodium level more than 160 mEq/L) to be relative exclusion criteria. The aim of our study is to review the postoperative outcomes of our simultaneous pancreas-kidney transplantation (SPKT) sample in terms of pancreatic fistula, intra-abdominal abscesses, pancreatitis, pancreas graft thrombosis, early pancreatectomy, and reoperation rates regarding different ranges of donor sodium levels. MATERIAL AND METHODS: We performed a retrospective analysis among 161 SPKTs performed in our center between the years 2001 and 2017. We compared the aforementioned postoperative variables in two situations: 1) Whether the donor pancreas sodium levels were inferior to 149 mEq/L, or equal to or greater than 150 mEq/L; and 2) If they had severe hypernatremia (considering sodium levels greater than or equal to 160 mEq/L as threshold) or not. To ensure the comparability of the groups, a second comparison was performed on new samples after using propensity score matching. A Student t test or Mann-Whitney U test was used for intergroup comparisons of quantitative variables where appropriate, whereas a chi2 test or Fisher's exact test was used to compare categorical data. RESULTS: No statistically significant differences were found between the groups that relate high donor serum sodium levels with the morbidity variables included in our study or with early pancreatic graft loss. CONCLUSIONS: In our cohort, early postoperative main morbidity and pancreas graft loss of SPKT recipients do not differ significantly regarding donor serum sodium levels. PMID- 29579887 TI - Donor Selection Based on Killer Cell Immunoglobulin-Like Receptor (KIR) Genotype May Improve Outcome After T-Cell-Replete Haploidentical Transplantation. AB - BACKGROUND: In haploidentical stem cell transplantation (SCT), the "ideal donor" selection is not performed in a standardized way according to killer cell immunoglobulin-like receptor (KIR) genotype expressed by potential donors. The aim of this study was to evaluate the relevance of KIR genotype in a series of patients submitted to haploidentical SCT in our center. METHODS: We retrospectively analyzed 30 patients that were prepared with the use of a conditioning regimen including thiotepa-busulfan-fludarabine with high doses of post-transplantation cyclophosphamide (CyPT) and tacrolimus as graft-versus-host disease (GVHD) prophylaxis. We analyzed the impact of the KIR genotype variables (donor AA/Bx haplotype, donor B content, KIR inhibitor mismatches, and mismatching in KIR ligands in the graft-versus-host direction and the host-versus graft direction) on overall survival, GVHD-free survival, and event-free survival. RESULTS: Statistical significance was found for the presence of mismatches on KIR ligands in the graft-versus-host direction in relation to the diagnosis of chronic GVHD (54% vs 100%; P = .004). Significance was also found for the effect of the donor presence AA or Bx haplotype in relation to the diagnosis of chronic GVHD (50% vs 86%; P = .033). CONCLUSIONS: KIR genotyping can provide useful information that can help us with the right donor choice for haploidentical SCT without T-cell depletion with high doses of CyPT. Donors with Bx haplotype that do not show KIR ligand incompatibilities in the graft-versus host direction may provide a lower risk of GVHD. PMID- 29579888 TI - Severe Scedosporium apiospermum Infection in a Recent Renal Transplant Recipient: Case Report. AB - Infections in transplanted patients are still an important cause of morbidity and mortality. Among them, fungal infections with pathogens have become increasingly more prevalent in the last decade. We report the clinical course and management of disseminated Scedosporium apiospermum infection in a kidney transplant recipient, with microbiological isolation of the fungus in cerebrospinal fluid culture. S apiospermum is a fungus that is distributed worldwide and can be grown from soil samples or stagnant water. Disseminated infection is the most frequent form of infection, with cerebral involvement in most cases, which leads to a very high mortality (around 75%). Post-transplant renal infections require a thorough evaluation. Specifically, a high suspicion index is necessary, considering Scedosporium infection among the differential diagnosis of invasive fungal diseases in renal transplantation patients. It is essential to confirm the microbiological diagnosis for an adequate diagnosis and treatment. PMID- 29579889 TI - Retransplant Due to Fulminant Hepatic Failure From Hepatitis E Virus: A Case Report. AB - Hepatitis E virus (HEV) usually causes self-limiting acute liver infections from fecal or oral transmission, though other routes of infection exist (vertical transmission, blood transfusion, zoonosis). It may give rise to fulminant hepatic failure in 1% of cases. Cases have recently been reported of chronic infection evolving to cirrhosis in immunosuppressed patients, such as those with a liver or kidney transplant. Nonetheless, development of acute liver failure in these patients is exceptional, with few cases published. We present a case of acute liver failure due to HEV in a liver transplant patient who required a liver retransplant 9 years after receiving the original transplant. PMID- 29579891 TI - Erratum. PMID- 29579890 TI - Molecular Adsorbent Recirculating System Treatment Can Reduce Blood Levels of N Acetylcysteine in Patients With Acetaminophen Overdose: Case Reports. AB - BACKGROUND: Acetaminophen poisoning continues to be a major cause of liver failure that can lead to liver transplantation. N-acetylcysteine (NAC) is the cornerstone of treatment. Some authors use a Molecular Adsorbent Recirculating System (MARS) system in acetaminophen poisoning. It is reported that the MARS system eliminates acetaminophen more efficiently than conventional dialysis. It is theoretically possible that treatment with MARS administered after NAC will increase the effectiveness of treatment. CASE REPORTS: The first patient, a woman of 14 years old, presented blood levels of 112 mg/dL 12 hours after ingestion of 15 g of acetaminophen. Treatment with NAC was initiated. At 17 and 23 hours after ingestion, blood levels were 23.5 MUg/mL and 5.9 MUg/mL, respectively. The second patient, a woman of 28 years old, presented blood levels of 115 mg/dL 4 hours after ingestion of 40 g of acetaminophen. Treatment with NAC was initiated. At 14 and 23 hours after ingestion, blood levels were 15.8 MUg/mL and <2 MUg/mL, respectively. In both patients, we performed MARS after completing treatment with NAC, and after the first session, blood levels were below the lower limit of detection (<=2 MUg/mL). DISCUSSION: The correct timing of MARS to avoid interactions with the administered dose of NAC in acetaminophen overdose is essential so as to not impair the effectiveness of this treatment. These considerations in the management of this entity help in the resolution of liver failure, thus avoiding the need for a liver transplant. PMID- 29579892 TI - Tds of cheese: Implications of analyzing texture and taste simultaneously. AB - This study aimed to evaluate the implications of analyzing texture and taste simultaneously on Temporal Dominance of Sensations (TDS) descriptions of Prato cheese. TDS tests were performed in two ways: I-panelists performed TDS tests of cheeses evaluating an attribute list with taste and texture sensations in a same session; II-TDS sessions were performed for each sensory modality. The difficulty and reliability degrees on performing the tests were assessed by the panelists; and some physico-chemical parameters were determined to compare the sensory and instrumental results. During TDS tests, simultaneous evaluations provided a higher number of significant sensations (considering both taste and texture sensations), but at lower dominance rates. Moreover, it was noted that one of the main implications of the simultaneous analysis on TDS results was the temporality differences (the time to reach the significance level, the sensation duration and the sensations sequence). However, regarding only the attributes that most characterized the samples, the results suggested a great similarity between the descriptions obtained from both TDS modalities. The simultaneous analysis implied greater difficulty in performing the tests and less reliable results according to the panelist's opinions. Moreover, the panel considered the texture evaluation more difficult than the taste evaluation. Regarding the instrumental analysis, the physico-chemical parameter intensity (amplitude) was not strongly linked to the maximum dominance rate. PMID- 29579893 TI - Environmental impacts of chocolate production and consumption in the UK. AB - This study evaluates life cycle environmental impacts associated with chocolate products made and consumed in the UK. The paper focuses on three representative chocolate products occupying 90% of the market: 'moulded chocolate', 'chocolate countlines' and 'chocolates in bag'. The impacts were estimated using life cycle assessment (LCA) as a tool and following the ReCiPe impact assessment method. The water footprint was also considered. For example, the global warming potential ranges between 2.91 and 4.15 kg CO2 eq., primary energy demand from 30 to 41 MJ and the water footprint, including water stress, from 31 to 63 l per kilogram of chocolate. The raw materials are the major hotspot across all impact categories for all three product types, followed by the chocolate production process and packaging. The raw material impacts are mainly due to milk powder, cocoa derivatives, sugar and palm oil. The sensitivity analysis shows that the results for global warming potential are sensitive to land-use change (LUC) associated with cocoa production, increasing the impact of the chocolate products by three to four times if LUC is involved. The improvement opportunities targeting the key contributing stages suggest that GWP of chocolates could be reduced by 14%-19%. Chocolate countlines have the highest contribution to the total impacts at the UK level (37%-43%), followed by chocolates in bag (28%-33%). Moulded chocolates and other chocolate confectionary make up the rest of the impacts, with a roughly equal share each. Chocolate consumption in the UK contributes 4.7% to the primary energy consumption and 2.4% to the GHG emissions from the whole food and drink sector. The results of this work will be of interest to policy makers, chocolate producers and consumers, helping them to make more informed decisions towards sustainable production and consumption of chocolate products. PMID- 29579894 TI - Synergistic effects of nutmeg and citrus peel extracts in imparting oxidative stability in meat balls. AB - Nutmeg (NM) and citrus peel (CP) extracts are potential sources of phytochemicals high in antioxidant activity. The synergistic effect of the extracts when incorporated as a binary mixture (NM-CP) demonstrated high antioxidant activity, exceeding the expected values indicating possible interactive synergism. This effect prompted us to investigate the potential of NM, CP and NM-CP extracts in imparting oxidative stability to meat balls during frozen storage. NM-CP was evaluated at two concentrations 0.5% (NMCP) and 1.0% (NMCP1). Meat balls with added salt (MS) and control (without any salt and antioxidant) served as control. Binary mixture (NM-CP) at 1% showed a stronger inhibitory effect on lipid oxidation in comparison to the NMCP and individual extracts NM and CP. However, with respect to protein oxidation, both concentrations (NMCP and NMCP1) exhibited higher inhibitory activity than the individual counterparts. Color, flavor and sensory scores further confirmed the efficacy of NM-CP in extending the storage life of frozen meat. Synergistic effect of binary extract NMCP in retarding lipid and protein oxidation in meat balls could be of practical value for meat processors. PMID- 29579895 TI - Evaluating the efficacy of turbimetric measurements as a rapid screening technique to assess fungal susceptibility to antimicrobial compounds as exemplified by the use of sodium metabisulfite. AB - The in vitro susceptibility to sodium metabisulphite (NaMBS) was investigated in 10 different food spoilage filamentous fungi, namely Aspergillus flavus, A. carbonarius, A. niger, A. ochraceus, A. tubingensis, A. westerdijkiae, Cladosporium cladosporioides, Fusarium oxysporum, Penicillium commune and P. expansum. The fungi were inoculated in sterile 96-well microtiter plates containing Yeast-extract Sucrose (YES) semi-solid agar supplemented with NaMBS in concentrations ranging from 2000 to 3.9 mg l-1 and incubated at 25 degrees C. Growth was monitored by absorbance measurements at 600 nm using a multi spectrophotometer. The surface areas under the optical density (OD) vs. time growth curves obtained were used to calculate the fractional area f(a), from which the non-inhibitory (NIC) and minimum inhibitory concentrations (MIC) of the antifungal agent were calculated for each fungus using the Gompertz model for decay. Most Aspergillus species showed remarkable resistance to NaMBS, presenting NIC and MIC values higher than 250 and 2500 mg l-1, respectively. The most susceptible fungi were the two Penicillium species and A. carbonarius, which presented very low NIC (<100 mg l-1) and MIC (<1300 mg l-1) values, whereas C. cladosporioides and F. oxysporum presented intermediate values. The method has the advantage of good repeatability and accuracy, rapid results within 48-72 h, growth detection and susceptibility to the antifungal agent for several fungi at the same time, and optimal use of microbiological media by using small volumes of consumables.

AB - The present study provides molecular insight into the effect of thymol and carvacrol on the oxidative damage caused to myofibrillar proteins by a hydroxyl radical generating system (HRGS). An innovative model system was designed, in which gels, prepared with increasing levels of myofibrillar proteins, were oxidized by a HRGS (Fe3+/H2O2, 60 degrees C and 7 days) in the presence of lipids. The molecular affinity between myofibrillar proteins and both terpenes, as well as their effect on the oxidative stability of the gel systems, were studied using a non-destructive and solvent-free procedure based on fluorescence spectroscopy. Carvacrol displayed more affinity than thymol for establishing chemical interactions with protein residues. Both terpenes exhibited a significant antioxidant potential against the generation of lipid-derived volatile carbonyls and against the formation of protein crosslinking. This procedure may be applied to meat products to assess the effectiveness of a given antioxidant additive without size reduction or sample processing. PMID- 29579897 TI - Quantitative risk assessment of antimicrobials in biosolids applied on agricultural land and potential translocation into food. AB - The use of biosolids as a fertiliser may be an indirect route for contaminants into the food chain. One of the main concerns regarding the spreading of biosolids on agricultural land is the potential uptake of contaminants into plants which may bio-transfer into grazing animals that supply the food chain directly (e.g. meat and milk) and hence are subsequently consumed. The aim of this project was to create a quantitative risk assessment model to estimate the fate and translocation of triclosan (TCS) and triclocarban (TCC) into the feed (grass) and food chain with subsequent human exposure. The model's results indicate that TCS and TCC have low potential to transfer into milk and beef following the ingestion of contaminated grass by dairy cows. Mean estimated TCS and TCC residues in milk and beef show that TCC had the greatest concentration (mean values of 7.77*10-6mgkg-1 in milk and 1.36*10-4mgkg-1 in beef). Human exposure results show that TCC was greater for milk consumption in infants (1 4years) (mean value 1.14*10-7mgkg-1bwd-1) and for beef consumption by teens (12 17years) (mean value 6.87*10-8mgkg-1bwd-1). Concentrations of TCS and TCC were well below the estimated acceptable daily intake (ADI). Human health risk was estimated by evaluation of the hazard quotient (HQ), which used the NOAEL as a toxicity endpoint, combined with milk and beef human exposure estimates. HQ results show that all values were <0.01 (no existing risk). A sensitivity analysis revealed that the Kow and initial concentration in biosolids as the parameters of greatest importance (correlation coefficients 0.91 and 0.19, respectively). This highlights the importance of physio-chemical properties of the compounds and their detection in biosolids post wastewater treatment along with their persistence in soil following application. This model is a valuable tool in which to ascertain the potential transfer of contaminants in the environment into animal forage with knock on consequences for exposure through the human food chain.

PMID- 29579899 TI - Use of Fourier transform infrared spectroscopy for monitoring the shelf life of ham slices packed with probiotic supplemented edible films after treatment with high pressure processing. AB - The aim of the present study was to investigate the potential use of Fourier transform infrared (FTIR) spectroscopy to quantify biochemical changes occurring in ham slices packed with probiotic supplemented edible films and treated with High Pressure Processing (HPP), in monitoring spoilage. Details regarding the data collection and experimental procedure were presented by Pavli et al. (2017). A series of Partial Least Squares (PLS) models were developed to correlate spectral data from FTIR analysis with ham spoilage during storage under vacuum at different temperatures (4, 8 and 12 degrees C). FTIR spectra were collected from the surface of the ham samples in parallel with microbiological analysis of total viable counts (TVC) and lactic acid bacteria (LAB). Qualitative interpretation of spectral data was based on a sensory evaluation, using a hedonic scale, classifying the samples in three quality classes, fresh, semi-fresh and spoiled. The scope of the modeling approach was to discriminate the ham slices in their respective quality class and additionally to predict the microbial population directly from spectral data. The results obtained demonstrated that the processing of the samples affected the performance of classification in the sensory classes, with better results observed in the case of for ham slices packed with probiotic supplemented (PS) edible films and of control samples without HPP. The performance of PLS regression models on providing quantitative estimations of microbial counts were based on specific figures of merit (bias factor, accuracy factor, root mean square error, percentage of prediction error). Bias and accuracy factors were close to unity for both microbial groups tested for samples without HPP, whereas for HPP treated samples the values of these indices ranged from 0.963 to 1.332, depending on the case and indice. The results of this study demonstrated for the first time that although FTIR can be used reliably for the rapid assessment of sliced ham, additional processes such as HPP can affect its performance. PMID- 29579900 TI - Development of fish-based model systems with various microstructures. AB - The effectiveness of predictive microbiology is limited by the lack of knowledge concerning the influence of food microstructure on microbial dynamics. Therefore, future modelling attempts should be based on experiments in structured food model systems as well as liquid systems. In this study, fish-based model systems with various microstructures were developed, i.e., two liquid systems (with and without xanthan gum), an emulsion, an aqueous gel, and a gelled emulsion. The microstructural effect was isolated by minimising compositional and physico chemical changes among the different model systems. The systems were suitable for common growth and mild thermal inactivation experiments involving both homogeneous and surface inoculation. Average pH of the model systems was 6.36+/ 0.03 and average aw was 0.988+/-0.002. The liquid system without xanthan gum behaved like a Newtonian fluid, while the emulsion and the liquid containing xanthan gum exhibited (non-Newtonian) pseudo-plastic behaviour. Both the aqueous gel and gelled emulsion were classified as strong gels, with a hardness of 1.35+/ 0.07N and 1.25+/-0.05N, respectively. Fat droplet size of the emulsion and gelled emulsion model systems was evenly distributed around 1MUm. In general, the set of model systems was proven to be suitable to study the influence of important aspects of food microstructure on microbial dynamics. PMID- 29579901 TI - Quantification of Campylobacter jejuni contamination on chicken carcasses in France. AB - Highly prevalent in poultry, Campylobacter is a foodborne pathogen which remains the primary cause of enteritis in humans. Several studies have determined prevalence and contamination level of this pathogen throughout the food chain. However it is generally performed in a deterministic way without considering heterogeneity of contamination level. The purpose of this study was to quantify, using probabilistic tools, the contamination level of Campylobacter spp. on chicken carcasses after air-chilling step in several slaughterhouses in France. From a dataset (530 data) containing censored data (concentration <10CFU/g), several factors were considered, including the month of sampling, the farming method (standard vs certified) and the sampling area (neck vs leg). All probabilistic analyses were performed in R using fitdistrplus, mc2d and nada packages. The uncertainty (i.e. error) generated by the presence of censored data was small (ca 1 log10) in comparison to the variability (i.e. heterogeneity) of contamination level (3 log10 or more), strengthening the probabilistic analysis and facilitating result interpretation. The sampling period and sampling area (neck/leg) had a significant effect on Campylobacter contamination level. More precisely, two "seasons" were distinguished: one from January to May, another one from June to December. During the June-to-December season, the mean Campylobacter concentration was estimated to 2.6 [2.4; 2.8] log10 (CFU/g) and 1.8 [1.5; 2.0] log10 (CFU/g) for neck and leg, respectively. The probability of having >1000CFU/g (higher limit of European microbial criterion) was estimated to 35.3% and 12.6%, for neck and leg, respectively. In contrast, during January-to-May season, the mean contamination level was estimated to 1.0 [0.6; 1.3] log10 (CFU/g) and 0.6 [0.3; 0.9] log10 (CFU/g) for neck and leg, respectively. The probability of having >1000CFU/g was estimated to 13.5% and 2.0% for neck and leg, respectively. An accurate quantification of contamination level enables industrials to better adapt their processing and hygiene practices. These results will also help in refining exposure assessment models. PMID- 29579902 TI - Plum (Prunus salicina) peel and pulp microparticles as natural antioxidant additives in breast chicken patties. AB - Fiber microparticles (MPCs) separately obtained from peel and pulp of Japanese plum residues contained co-extracted beta-carotene, lutein, and alpha- and gamma tocopherols, as well as polyphenols (cyanidins, quercetin derivatives, pentameric proanthocyanidins). Peel and pulp MPCs were then separately evaluated as natural antioxidant additives (2.0% w/w level) in raw breast chicken patty, susceptible to oxidation. Their effect on technological properties was also analyzed. MPCs reduced in 50% the formation of thiobarbituric acid reactive substances (TBARS) in raw patties during 10-days storage at 4.0 degrees C. Ferric reducing power (FRAP) was 77-157% higher in MPCs-added patties, especially with peel MPCs, being then attributed to the antioxidants supplied by these MPCs. It can be also associated to the highest alpha- and gamma-tocopherol levels found in the peel MPCs-added patties, which remained high after cooking as well. Also, higher pectin and low lignin contents of pulp MPCs determined greater hydration, stabilized the cyanidins and, hence, the red color transferred to raw patties, and increased springiness of cooked patties. Plum peel and pulp MPCs are efficient additives for chicken meat products. PMID- 29579903 TI - Berries extracts as natural antioxidants in meat products: A review. AB - The aim was to evaluate antioxidants from berries as replacement food additives for inhibition of lipid and protein oxidation in meat and meat products, since meats are highly susceptible to oxidation. Oxidation can be delayed/retarded by synthetic antioxidants with phenolic structures (e.g. butylated hydroxytoluene). However, new natural alternatives are needed for synthetic antioxidants due to the controversy regarding their possible negative health effects and consumers' demand for more 'natural' food additives. Berries are a good source of phenolic compounds, especially anthocyanins, which can be used as the potential alternative. Reviewed berries included bearberry (Arctostaphylos sp.), blueberry (Vaccinium sp.), blackberry (Rubus sp.), blackcurrant (Ribes nigrum), cranberry (Vaccinium sp.), cloudberry (Rubus chamaemorus), strawberry (Fragaria ananassa), and grape berries (Vitis sp.). Data implied that blueberries, blackberries, cranberries, and grapes can be useful for replacing/decreasing synthetic antioxidants in meat products. Their extracts have antioxidant polyphenols with health benefits that are useful for stabilizing meat products. PMID- 29579904 TI - Wine tasting based on emotional responses: An expedite approach to distinguish between warm and cool climate dry red wine styles. AB - In this study, we improved an empirical tasting sheet including emotional responses and common sensory attributes. An Optimized Descriptive Profile (ODP) was run to characterize different red wines according to sensory descriptors used in the improved sheet. A total of 5 wines were evaluated by a Consumer Panel (CP) of 103 subjects (36 females, 67 males) using the improved sheet and a Check-All That-Apply (CATA) list of 25 emotions. In the ODP, the panel identified the main discriminating sensory attributes as "Complexity", "Astringency" and "Duration of the wine fragrance". However, this analysis did not allow for differentiating very distinct dry red wine styles originating from warmer or cooler regions. On the contrary, Principal Component Analysis of emotional attributes demonstrated that these two wine styles could be easily distinguished. In particular, wine with a red-brick color, complex smell and aggressive mouthfeel consistent with those from cooler regions was less liked by the CP than a warm climate gold awarded wine. Although receiving lower scores considering its color and smell, the former wine was regarded as the most "surprising" in the CATA. PMID- 29579905 TI - Parameter estimations in predictive microbiology: Statistically sound modelling of the microbial growth rate. AB - When building models to describe the effect of environmental conditions on the microbial growth rate, parameter estimations can be performed either with a one step method, i.e., directly on the cell density measurements, or in a two-step method, i.e., via the estimated growth rates. The two-step method is often preferred due to its simplicity. The current research demonstrates that the two step method is, however, only valid if the correct data transformation is applied and a strict experimental protocol is followed for all experiments. Based on a simulation study and a mathematical derivation, it was demonstrated that the logarithm of the growth rate should be used as a variance stabilizing transformation. Moreover, the one-step method leads to a more accurate estimation of the model parameters and a better approximation of the confidence intervals on the estimated parameters. Therefore, the one-step method is preferred and the two step method should be avoided. PMID- 29579906 TI - Growth of Listeria monocytogenes in pasteurized vanilla cream pudding as affected by storage temperature and the presence of cinnamon extract. AB - The objective of the present study was the assessment and quantitative description of the growth behavior of Listeria monocytogenes as a function of temperature in vanilla cream pudding, formulated with or without cinnamon extract. Commercially prepared pasteurized vanilla cream pudding, formulated with (0.1% w/w) or without cinnamon extract, was inoculated with a five-strain mixture of L. monocytogenes (ca. 2logCFU/g) and stored aerobically at 4, 8, 12 and 16 degrees C. At appropriate time intervals, L. monocytogenes populations were determined, and the primary model of Baranyi and Roberts was fitted to the derived microbiological data for the estimation of the pathogen's growth kinetic parameters. The effect of temperature on maximum specific growth rate (MUmax) was then modeled for each product type using a square-root-type model, and the developed models were validated using independent growth data generated during storage of inoculated vanilla cream samples under dynamic temperature conditions. Although the kinetic behavior of the pathogen was similar in cream with and without cinnamon extract during storage at higher temperatures, significant (P<0.05) differences were observed between the two product types at 4 degrees C. With regard to secondary modelling, the estimated values of Tmin for cream with and without cinnamon extract were 0.39 degrees C and -2.54 degrees C, respectively, while the dynamic models exhibited satisfactory performance. Finally, as demonstrated by the findings of pulsed-field gel electrophoresis, both temperature and cinnamon extract affected the pathogen's strains dominating during storage. According to the collected data, cinnamon extract exhibits an important potential of enhancing the microbiological safety of vanilla cream pudding, provided that efficient temperature control is in place. The developed models should be useful in quantitative microbial risk assessment regarding the studied cream products. PMID- 29579907 TI - An interaction model for the combined effect of temperature, pH and water activity on the growth rate of E. coli K12. AB - Previous research has indicated that more complex model structures than the commonly used gamma model are needed to obtain an accurate prediction of the effect of multiple environmental conditions on the microbial growth rate. Due to the complexity associated with the development of such model structures, it is recommended that the model structure is compatible with a modular model building method. In this research, a gamma-interaction model was built to describe the combined effect of temperature, pH and water activity on the microbial growth rate of E. coli K12 based on a dataset of 68 bioreactor experiments. This novel interaction model was compared with the standard gamma model. The model structures were tested separately for the combined effects of (i) temperature and pH, (ii) pH and water activity, (iii) temperature and water activity and (iv) temperature, pH and water activity. Based on the results of this research, it was concluded that models for the combined effect of environmental conditions need to allow for sufficient flexibility for the description of combined effects of environmental conditions to obtain accurate model predictions. In the current study, this flexibility was successfully introduced by using the gamma interaction model. A cross-validation study also demonstrated that the predictions of the interaction model are more robust with respect to the specific data used than the gamma model. As such, the gamma-interaction model provides food producers and food safety authorities with a more accurate and reliable tool for the prediction of the microbial growth rate as a function of multiple environmental conditions. PMID- 29579908 TI - Quantitative microbiological risk assessment in food industry: Theory and practical application. AB - The objective of this article is to bring scientific background as well as practical hints and tips to guide risk assessors and modelers who want to develop a quantitative Microbiological Risk Assessment (MRA) in an industrial context. MRA aims at determining the public health risk associated with biological hazards in a food. Its implementation in industry enables to compare the efficiency of different risk reduction measures, and more precisely different operational settings, by predicting their effect on the final model output. The first stage in MRA is to clearly define the purpose and scope with stakeholders, risk assessors and modelers. Then, a probabilistic model is developed; this includes schematically three important phases. Firstly, the model structure has to be defined, i.e. the connections between different operational processing steps. An important step in food industry is the thermal processing leading to microbial inactivation. Growth of heat-treated surviving microorganisms and/or post-process contamination during storage phase is also important to take into account. Secondly, mathematical equations are determined to estimate the change of microbial load after each processing step. This phase includes the construction of model inputs by collecting data or eliciting experts. Finally, the model outputs are obtained by simulation procedures, they have to be interpreted and communicated to targeted stakeholders. In this latter phase, tools such as what if scenarios provide an essential added value. These different MRA phases are illustrated through two examples covering important issues in industry. The first one covers process optimization in a food safety context, the second one covers shelf-life determination in a food quality context. Although both contexts required the same methodology, they do not have the same endpoint: up to the human health in the foie gras case-study illustrating here a safety application, up to the food portion in the brioche case-study illustrating here a quality application. PMID- 29579909 TI - Determining quality parameters of fish oils by means of 1H nuclear magnetic resonance, mid-infrared, and near-infrared spectroscopy in combination with multivariate statistics. AB - Fish oil is becoming increasingly popular as a dietary supplement as well as for its use in animal feed, which is mainly due to its high contents of the health promoting omega-3 fatty acids. However, these polyunsaturated fatty acids are highly susceptible to oxidation, which results in a decrease of the fish oil quality. This study investigated the potential of 1H NMR, FT-MIR, and FT-NIR spectroscopy in the quality assessment of fish oils. A total of 84 different fish oils, of which 22 were subjected to accelerated storage with varying temperature and light exposure, were used to develop models for predicting the peroxide value (PV), the anisidine value (AnV), and the acid value (AV). Predictions were based on comprehensive spectroscopic data in combination with Artificial Neural Networks (ANN) as well as Partial Least Squares Regression (PLSR). The best ANN model for PV was obtained from NMR data, with a predictive coefficient of determination (Q2) of 0.961 and a Root Mean Square Error of Prediction (RMSEP) of 1.5meqO2kg-1. The combined MIR/NIR data provided the most reliable ANN model for AnV (Q2=0.993; RMSEP=0.74). For AV, the ANN model based on the MIR data yielded a Q2 of 0.988 and an RMSEP of 0.43mgNaOHg-1. In most cases, the accuracy of the ANN models was superior to the respective PLSR models. Variable selection and data dimensionality reduction turned out to improve the performance of the ANN models in some cases. The application of 1H NMR, FT-MIR, and FT-NIR spectroscopy in combination with ANN can be considered very promising for a rapid, reliable, and sustainable assessment of fish oil quality. PMID- 29579910 TI - Effect of dietary fiber (inulin) addition on phenolics and in vitro bioaccessibility of tomato sauce. AB - The effect of the addition of inulin (5 and 10%) on the phenolic content and in vitro gastrointestinal digestion of tomato sauces has been investigated. Results have shown that the addition of inulin to tomato sauce significantly decreased the total phenolic content (57-68%), total flavonoid content (48-60%), and total antioxidant capacity (49-61%). Similarly, all assays of the sauce containing both 5% and 10% inulin, showed a slight decrease during in vitro gastrointestinal digestion of tomato sauces. Higher levels of inulin added to tomato sauce resulted in the greatest decrease in phenolic content, probably because of the interaction between inulin and phenolic compounds. To address the effects of inulin on the global metabolite profile of tomato sauce, an untargeted metabolomics approach was followed. Changes related to the presence of inulin suggest that inulin quenches a subset of unidentified compounds which are present in sauce but not in fruit, suggesting that inulin can contribute to the conservation of fruit properties in tomato sauce. PMID- 29579911 TI - Aflatoxigenic and ochratoxigenic fungi and their mycotoxins in spices marketed in Brazil. AB - During their processing, spices usually remain close to the ground for drying, a fact that disposes to fungal contamination, as well as moisture transferred from the tropical environment can allow their multiplication and synthesis of mycotoxins. The objective of this study was to evaluate the presence of potentially toxigenic fungi and mycotoxins in spices marketed in Brazil. The fungal contamination was evaluated by direct plating for samples of clove, black and white peppers. Spread plate was used for the samples of rosemary, cinnamon, fennel, pepperoni pepper and oregano. Analyses were performed in triplicate in DG18 media with incubation at 25 degrees C for 7days. The isolation and identification of fungi followed specific recommendations of culture media and incubation period for each genus. The presence of mycotoxins in spices was verified by high-performance liquid chromatography (HPLC) coupled to fluorescence. The frequency of species potentially toxigenic was high in white and black peppers with presence of both aflatoxigenic and ochratoxigenic fungi. Only rosemary and fennel showed contamination with aflatoxin B1 and there was a positive correlation (rho<0.01) between the rosemary contamination with the presence of AFB1 and A. flavus. Even in the presence of ochratoxigenic fungi, ochratoxin A was not detected in the samples. The presence of natural components with antimicrobial activity could justify the low presence of mycotoxins, even in the presence of known toxigenic fungi in the samples. Mycotoxins were not detected in spices covered by Brazilian regulation of mycotoxins. On the other hand, these contaminants were present in other spices consumed by population and not mentioned in the regulation, which could be considered a cause to concern. PMID- 29579912 TI - Fungi in cake production chain: Occurrence and evaluation of growth potential in different cake formulations during storage. AB - This study aimed to determine the prevalence and populations of fungi in cake production chain. Besides, the growth potential of twelve fungal strains in different cake formulations was evaluated. Raw materials from two different batches (n=143), chocolate cakes (n=30), orange cakes (n=20), and processing environment air samples (n=147) were analyzed. Among the raw materials, wheat flour (3.2+/-0.3 log CFU per g) and corn meal (3.8+/-0.8 log CFU per g) belonging to batch #1 showed significant higher fungal counts (p<0.05). The fungal counts in the processing environment air reached up to 2.56 log CFU per m3 (p<0.05). The predominant fungi species in the industrialized cakes were Aspergillus flavus (28.15%), Penicillium citrinum (18.45%), Penicillium paxilli (14.56%), and Aspergillus niger (6.8%), which were also detected in the raw materials and processing environment air. Only Penicillium glabrum and Penicillium citrinum showed visible mycelium (>3mm) in the free of preservative cake formulation at 19th and 44th days of storage at 25 degrees C, respectively. Revealing the biodiversity of fungi in ingredients, air and final products, as well as challenging final products with representative fungal strains may assist to implement effective controlling measures as well as to gather data for the development of more robust cake formulations. PMID- 29579913 TI - Absorption kinetics of vitamin E nanoemulsion and green tea microstructures by intestinal in situ single perfusion technique in rats. AB - The absorption kinetics of food ingredients such as nanoemulsified vitamin E and green tea microstructures were evaluated by the intestinal in situ single perfusion technique. Absorption rate, sub-acute oral toxicity and organ morphology in a rat model were examined. The intestinal in situ single perfusion technique and HPLC analysis were applied to investigate the absorption rate of selected materials by examining time-dependent changes in the serum levels of catechin and dl-alpha-tocopherol. The acute toxicity test and histopathological evaluation were applied to analyze the safety of microsized green tea and nanosized vitamin E in a rat model. Total serum dl-alpha-tocopherol levels significantly increased with nanosized vitamin E administration (P<0.05). Rats treated to nanosized vitamin E until 90min after administration showed significantly increased absorption rate of serum dl-alpha-tocopherol levels at each time point (10min interval) (P<0.001). Rats administered 2000mg/kg of nanosized vitamin E and microsized green tea did not show signs of acute toxicity or death after 14days of observation. In addition, macroscopic analysis showed that there were no changes in representative organ sections of rats following the oral administration of food-related nanoscale materials. We successfully demonstrated that using nanosized vitamin E increased absorption rate to a greater extent than normal food-related material, and these results occurs via safety analyses on food-related nanoscale materials for human consumption. These results could be useful for the design and development of novel nanoemulsified vitamin E and microsized green tea formulations that can overcome the problem of their bioavailability and improve their efficacy while still maintaining their essential therapeutic efficacies. PMID- 29579914 TI - Characterization of taste and aroma compounds in Tianyou, a traditional fermented wheat flour condiment. AB - Taste and aroma compounds in Tianyou were determined using HPLC and GC-MS/GC olfactometry. By comparison with light soy sauce (control), the contents of salt, sugar, total nitrogen and total acid in Tianyou were higher, while the contents of umami, sweet and bitter free amino acids, and the percentage of 1-5kDa peptides in Tianyou were lower. Thirty-one aroma-active compounds were identified in both Tianyou and the control (30 compounds in common). Aroma extraction dilution analysis indicated that most flavor dilution factors of aroma-active compounds were lower in Tianyou than the control. Quantitative descriptive analysis showed that Tianyou had significantly stronger salty and sweet tastes, weaker umami taste and weaker malty, caramel-like and smoky notes when compared to the control (p<0.05), which were in agreement with the analyses of taste and aroma compounds. This confirms that Tianyou has a distinctively different flavor from light soy sauce. PMID- 29579915 TI - Specialized oxygenated heterocyclics from Villorita cyprinoides with cyclooxygenase-2 and 5-lipoxygenase inhibitory properties. AB - Villorita cyprinoides is traditional seafood in the coastal regions of Arabian Sea. Bioactivity-guided purification of ethyl acetate:methanol extract of V. cyprinoides resulted in the identification of two O-spirocyclic ether derivatives (1-2) along with one O-heterocyclic irregular meroterpenoid (3). The structures and their relative stereochemistries were elucidated through comprehensive spectroscopic experiments. These specialized metabolites were found to exhibit potential antioxidative (IC50<0.70mg/mL) and anti-inflammatory activities against pro-inflammatory inducible 5-lipoxygenase (anti-5-LOX IC50<=0.80mg/mL) and cyclooxygenase-2 (anti-COX-2 IC50<0.75mg/mL) enzymes. Molecular docking simulations were used to describe the interactions of the isolated compounds (ligands) with COX-2 and 5-LOX inflammation model. The permissible hydrophobic hydrophilic balance and lesser steric bulk of spirocyclic ether derivative (compound 2), along with greater number of hydrogen bonding interactions in the active sites of COX-2 and 5-LOX manifested towards its greater bioactivities compared to other compounds isolated from V. cyprinoides. PMID- 29579916 TI - Effect of technological treatments on bovine lactoferrin: An overview. AB - Lactoferrin (LF) is a multifunctional protein that exerts important activities in the neonate through its presence in milk, and also in other external mucosas, acting as a defense protein of innate immunity. The addition of bovine LF to infant formula and also to other functional products and cosmetics has increased during the last decades. Consequently, it is essential to know the effect that the technological processes, necessary to elaborate those products, have on LF activity. In this study, we have revised the effect of classical treatments on lactoferrin structure and activity, such as heat treatment or drying, and also of emerging technologies, like high pressure or pulsed electric field. The results of the studies included in this review indicate that LF stability is dependent on its level of iron-saturation and on the characteristics of the treatment media. Furthermore, the studies revised here reveal that the non-thermal treatments are interesting alternatives to the traditional ones, as they protect better the structure and activity of lactoferrin. It is also clear the need for research on LF encapsulation by different ways, to protect its properties before it reaches the intestine. All this knowledge would allow designing processes less harmful for LF, thus maintaining all its functionality. PMID- 29579917 TI - Factors affecting migration kinetics from a generic epoxy-phenolic food can coating system. AB - This study investigated how the properties of a polymeric can coating film, such as thickness and crosslink density as well as the type of migrant, influence the migration kinetics of model migrants in an attempt to better understand, model and control the migration process. Four model migrants were used BADGE (bisphenol A diglycidyl ether), BADGE.H2O, cyclo-diBADGE and Uvitex OB, that differ in size and polarity. Fatty and aqueous food simulants were used at high temperatures (70 130 degrees C). The apparent diffusion coefficients were found to decrease with increasing crosslink density, while they increased with increasing film thickness. The apparent activation energy of BADGE and BADGE-related compounds was calculated from the diffusion data and were high, in the range of 250 264kJmol-1. The polarity of the simulant and the polarity of the migrant were found to influence migration. The results can be used to improve existing migration models, and thereby help to reduce migration from packaging into food by using safety-by-design approaches in new product development. PMID- 29579919 TI - Extensional and shear rheology of okra hydrocolloid-saliva mixtures. AB - This is an investigation of the shear and extensional properties of okra polysaccharide-saliva mixtures, intended to model the mechanical behavior a food hydrocolloid during oral processing. Shear measurements show that incorporation of okra mucilage in saliva interferes with the self-assembly of salivary mucins, with partly detrimental effects on the low-shear viscosity of the mixture. This is counter-acted by excluded volume effects, as the overall concentration of macromolecules in the mixture reaches the semi-dilute regime. Particle tracking confirms the lack of direct interactions between the two polymeric populations. The contribution of extensional viscosity to the overall behavior of okra hydrocolloid-saliva mixtures is dominant, at about one to two orders of size higher than the equivalent shear values. The Trouton ratio values are in the order of tens or hundreds for the range of concentrations and deformation rates under study. Although the extensional viscosity dominates viscous flow, the two types of flow are equally important concerning the elastic behavior, giving insight on the mechanical behavior of mucilages in the oral cavity.

AB - Hyperspectral imaging (HSI) is a novel technology for the food sector that enables rapid non-contact analysis of food materials. HSI was applied for the first time to whole green coffee beans, at a single seed level, for quantitative prediction of sucrose, caffeine and trigonelline content. In addition, the intra bean distribution of coffee constituents was analysed in Arabica and Robusta coffees on a large sample set from 12 countries, using a total of 260 samples. Individual green coffee beans were scanned by reflectance HSI (980-2500nm) and then the concentration of sucrose, caffeine and trigonelline analysed with a reference method (HPLC-MS). Quantitative prediction models were subsequently built using Partial Least Squares (PLS) regression. Large variations in sucrose, caffeine and trigonelline were found between different species and origin, but also within beans from the same batch. It was shown that estimation of sucrose content is possible for screening purposes (R2=0.65; prediction error of ~0.7% w/w coffee, with observed range of ~6.5%), while the performance of the PLS model was better for caffeine and trigonelline prediction (R2=0.85 and R2=0.82, respectively; prediction errors of 0.2 and 0.1%, on a range of 2.3 and 1.1% w/w coffee, respectively). The prediction error is acceptable mainly for laboratory applications, with the potential application to breeding programmes and for screening purposes for the food industry. The spatial distribution of coffee constituents was also successfully visualised for single beans and this enabled mapping of the analytes across the bean structure at single pixel level.

AB - In a multi-component chocolate product, oil migration, from high oil content filling into chocolate, is one of the major contributors to the product quality loss. Among various parameters influencing oil diffusivity, cocoa butter is studied intensively. Studies have shown that the rate of oil transportion in cocoa butter is affected by its composition, the way that it is crystallized, and also the storage conditions. To model and study effects of cocoa butter type and processing conditions on oil migration, five different cocoa butter samples were studied in this work. Samples' chemical compositions in addition to their structural properties were analyzed to understand and compare oil migrations in the networks. Crystallized cocoa butter samples were placed in contact with a cream as a source of liquid oil. Using Magnetic Resonance Imaging, the movement of liquid oil into samples was investigated. The effects of minor differences in the cocoa butter chemical compositions on oil migrations rate are shown clearly. The highest effective diffusion coefficient was observed in the sample with the higher unsaturated fatty acids and phospholipids content. Although shearing at 250s-1 delayed oil migration in all the samples and a significantly lower diffusion coefficient was observed in the dynamic samples, the effects of chemical composition were still dominant. This study successfully highlighted that even minor differences in cocoa butter composition affect the network mass transfer phenomenon dramatically and that it is not easy to diminish these possessions by just crystallization processes.

AB - The ability of Patagonian L. plantarum and O. oeni strains to change the volatile profile of a sterile Pinot noir wine was studied through fermentation assays, at laboratory scale. Two strains of each LAB species were selected based on data regarding to their ability to survive in wine and to consume l-malic acid. Both O. oeni strains but only one L. plantarum (UNQLp 11) strain were able to remain viable, consuming l-malic acid through the fermentation assay with a concomitant increase of l-lactic acid. The volatile profile of Pinot noir wine, before and after LAB inoculation, was measured by using HS-SPME gas chromatography technique. This analysis showed that alcohols were the main volatile compounds after alcoholic fermentation and that after fermentation with the selected LAB strains, a decrease in the volatile alcohols concentration and an increase in the volatile esters concentration could be observed. The O. oeni UNQOe 73.2 strain produced the most notable change in the volatile profile, with the production of some important odorant esters at higher concentration, compared to O. oeni UNQOe 31b strain. Although, L. plantarum UNQLp 11 strain showed a better performance in the consumption of l-malic acid, this strain had a low capacity to modify the volatile compounds profile after incubation in red wine. The results found in the present work showed that different strains selected as potential malolactic starters could have different behavior when are incubated in real wine. Although L. plantarum UNQLp 11 strain showed a good consumption of l-malic acid, the O. oeni UNQOe 73.2 strain exhibited superior capacity to improve the flavor of wine due to its esterase activity that produce an increase of fruity and creamy odorants. PMID- 29579922 TI - MLVA subtyping of Listeria monocytogenes isolates from meat products and meat processing plants. AB - Listeria monocytogenes is widely distributed in meat products and the meat processing industry thus posing a risk to consumers. The aim of this study was to evaluate the suitability of the multilocus variable-number tandem-repeat analysis (MLVA) for use as a L. monocytogenes subtyping technique for surveillance and routine control in meat products and meat processing plants. A collection of 113 isolates (including control strains and isolates from meat products and meat processing plants) were subject to MLVA analysis using two different platforms for fragment sizing: 1.) ABI 3730xl DNA analyzer (Life Technologies) as the reference method and 2.) The QIAxcel Advanced System (Qiagen). Although discrepancies in fragment sizing were observed it was possible to standardize results in order to assign the same allele for a given fragment independently of the platform used for fragment sizing. A total of 27 different MLVA profiles were obtained considering all the isolates (N=113), 24 of them corresponding to the meat industry isolates (N=106). MLVA and multilocus sequence typing (MLST) results were compared and yielded Simpson's diversity indices of 0.907 and 0.872, respectively. The congruence between both typing methods was measured with the adjusted Wallace coefficient (AW). Using MLVA as the primary method, AW=0.946 suggested that MLVA can predict the sequence type with high accuracy. Given its discriminatory power and high throughput, MLVA could be considered a rapid, reliable, and high-throughput alternative to existing subtyping methods for surveillance and control of L. monocytogenes in the meat-processing industry. PMID- 29579923 TI - A metabolic fingerprinting approach based on selected ion flow tube mass spectrometry (SIFT-MS) and chemometrics: A reliable tool for Mediterranean origin labeled olive oils authentication. AB - Selected Ion flow tube mass spectrometry (SIFT-MS) in combination with chemometrics was used to authenticate the geographical origin of Mediterranean virgin olive oils (VOOs) produced under geographical origin labels. In particular, 130 oil samples from six different Mediterranean regions (Kalamata (Greece); Toscana (Italy); Meknes and Tyout (Morocco); and Priego de Cordoba and Baena (Spain)) were considered. The headspace volatile fingerprints were measured by SIFT-MS in full scan with H3O+, NO+ and O2+ as precursor ions and the results were subjected to chemometric treatments. Principal Component Analysis (PCA) was used for preliminary multivariate data analysis and Partial Least Squares Discriminant Analysis (PLS-DA) was applied to build different models (considering the three reagent ions) to classify samples according to the country of origin and regions (within the same country). The multi-class PLS-DA models showed very good performance in terms of fitting accuracy (98.90-100%) and prediction accuracy (96.70-100% accuracy for cross validation and 97.30-100% accuracy for external validation (test set)). Considering the two-class PLS-DA models, the one for the Spanish samples showed 100% sensitivity, specificity and accuracy in calibration, cross validation and external validation; the model for Moroccan oils also showed very satisfactory results (with perfect scores for almost every parameter in all the cases). PMID- 29579924 TI - Unlocking Phacelia tanacetifolia Benth. honey characterization through melissopalynological analysis, color determination and volatiles chemical profiling. AB - Phacelia tanacetifolia Benth. honey (14 samples) collected in Poland was characterized by melissopalynological analysis, color determination (CIE L*a*b*Cab*hab degrees coordinates) and volatiles (VOCs) composition. VOCs were isolated by headspace solid-phase microextraction (HS-SPME, two fibers) and ultrasound-assisted solvent extraction (USE, two solvents) and analyzed by GC-MS. Principal component analysis (PCA) and hierarchical-tree clustering (HTC) were applied to show trends and form groups and to indicate the most representative unifloral samples. Six samples were pointed out with average pollen 74.9% and color parameters (L=85.1; a*=-0.8; b*=27.9; Cab*=27.9; hab*=91.9) that were significantly correlated. High abundance of trans-linalool oxide (27.3-45.9%) that was significantly correlated with the pollen percentages, hexan-1-ol (4.4 5.7%) and lavender lactone (0.8% - 1.5%) were characteristic for their headspace. C13-norisoprenoids, mainly (E)-/(Z)-3-oxo-retro-alpha-ionol (4.7-5.4%; 6.9-9.4%) and vomifoliol (9.0-13.0%) dominated in their USE extracts. PMID- 29579925 TI - Impact of starter culture, ingredients, and flour type on sourdough bread volatiles as monitored by selected ion flow tube-mass spectrometry. AB - This study deals with the detection of volatile compounds originating from the crumb of breads made with sourdoughs obtained through starter culture-initiated fermentations, which differed in flour type (wheat and teff), ingredients (citrate and malate), fermentation time (24h or 72h), and starter culture strains (homo- and heterofermentative lactic acid bacteria species and acetic acid bacteria species) applied. Therefore, selected ion flow tube-mass spectrometry (SIFT-MS) was used. SIFT-MS is an easy-to-use and promising technique in the field of food and flavor analysis. Volatile compounds of crumb samples from the breads with sourdough were measured and compared with those of reference bread crumb samples. In general, sourdough addition had a positive effect on the concentrations of the volatile compounds measured by SIFT-MS. Furthermore, a trend toward higher concentrations of several volatiles was seen upon the addition of sourdoughs that were fermented up to 72h, compared to the addition of sourdoughs that were fermented for a shorter time. Ethanol was the major volatile compound identified tentatively, next to alcohols, aldehydes, esters, terpenes, and heterocyclic compounds. Also acetoin/ethyl acetate could be identified, but these compounds could not be distinguished. Higher alcohols showed an increase upon the use of sourdough fermented for a long time. High concentrations of acetic acid were found in breads made with Gluconobacter oxydans IMDO A845 initiated sourdough, indicating its potential for sourdough production. Breads made with teff sourdoughs were distinct from wheat-based sourdough breads as to their volatile compound profiles. PMID- 29579926 TI - An 1H NMR-based metabolomic approach to compare the chemical profiling of retail samples of ground roasted and instant coffees. AB - The present non-targeted 1H NMR-based fingerprinting approach along with multivariate analysis established differences between representative aqueous extracts of commercial ground roasted coffee (GRC) and instant (soluble) coffee (IC) samples. The latter were prepared either by spray drying or freeze drying. When comparing a total of 33 compounds between GRC and IC, the latter product contained a remarkable increase in 5-(hydroxymethyl)furfural and carbohydrates, as well as a clear decrease in trigonelline, N-methylpyridinium, caffeine, caffeoylquinic acids and 2-furylmethanol. Furthermore, the current protocol was able to detect the subtle chemical differences between spray-dried and freeze dried IC. The aforementioned metabolites could serve as target molecules in the attempt to preserve, as much as possible, the organoleptic and nutraceutical properties of GRC during the industrial drying processes used in the production of the two commercial types of IC. PMID- 29579927 TI - Recovery of soluble proteins from migratory locust (Locusta migratoria) and characterisation of their compositional and techno-functional properties. AB - Edible insects emerged as an alternative source of high-quality proteins. Therefore, the effect of an extraction procedure for the recovery of migratory locust (Locusta migratoria) protein concentrate (MLPC) on the compositional characteristics and techno-functional properties was studied. The influence of pH value (2-10) and salt concentration (0, 1 and 3% w/v) on techno-functional properties was evaluated. Proteins were identified and characterized by RP-HPLC, SDS-PAGE and LC-MS/MS. The initial crude protein content of the whole locusts (65.9% on dry base) could be enhanced to 82.3% (MLPC). Solubility profiles of MLPC showed maximum solubility at pH9 (100%). Promising functionality comparable to egg white protein in terms of emulsifying activity at pH5, foamability at pH3 and 3% NaCl, and foam stability at pH9 were found. Consequently, MLPC offers a nutritious protein source with good functional properties at certain conditions, which could be used as food ingredient in a variety of food systems. PMID- 29579928 TI - Thymol/cyclodextrin inclusion complex nanofibrous webs: Enhanced water solubility, high thermal stability and antioxidant property of thymol. AB - The development of novel nanomaterials that provide an efficient encapsulation and protection for the active food additives is one of the main focuses of current research efforts at food application areas. From this point of view, in this study, nanofibrous webs from inclusion complexes (IC) of modified cyclodextrins (hydroxypropyl-beta-cyclodextrin (HPbetaCD), hydroxypropyl-gamma cyclodextrin (HPgammaCD) and methyl-beta-cyclodextrin (MbetaCD)) and essential oils compound (i.e. thymol) was produced through electrospinning technique. While pure thymol has a highly volatile nature, the volatility of thymol was effectively suppressed by the inclusion complexation and ~88-100% (w/w) of thymol was preserved in electrospun thymol/cyclodextrin inclusion complex nanofibers (Thymol/CD-IC NF). The aqueous solubility enhancement for hydrophobic thymol was demonstrated by phase solubility diagram which also suggested the 1:1M inclusion complexation between thymol and CD molecules. Besides, Thymol/CD-IC NF displayed quite fast disintegration in water compared to poorly water soluble thymol. By inclusion complexation, high temperature stability for volatile thymol was achieved for Thymol/CD-IC NF samples. The loading of thymol in Thymol/CD-IC NF conferred DPPH radical scavenging ability to these nanofibrous webs. So, the Thymol/CD-IC NF have shown antioxidant activity along with enhanced water solubility and high thermal stability of thymol. In brief, encapsulation of essential oil compounds such as thymol in electrospun CD-IC nanofibers can promote its potential application in food and oral-care products by associating the large surface area of nanofibrous webs along with CD inclusion complexation which provides enhanced water solubility and antioxidant property, and high temperature stability for thymol. PMID- 29579929 TI - Evaluation of the Pivot Profile(c), a new method to characterize a large variety of a single product: Case study on honeys from around the world. AB - Honey is a natural product with very diverse sensory attributes that are influenced by the flower source, the bee species, the geographic origin, the treatments and conditions during storage. This study aimed at describing 50 honeys from diverse flower sources in different continents and islands, stored under various conditions. Many articles have been published on the sensory characterization of honeys, thus a common list of attributes has been established, but it appeared to be poorly suited to describe a large number of honeys from around the world. This is why the novel and rapid sensory evaluation method, the Pivot Profile(c), was tested, with the participation of 15 panelists during five sessions. The first objective was to obtain a sensory description of the 50 honeys that were tested. From 1152 distinct terms, a list of 29 sensory attributes was established and the attributes divided into three categories: color/texture (8 terms), aroma (16 terms), and taste (5 terms). At first, the honeys have been ranked according to their level of crystallization from fluid/liquid to viscous/hard. Then color was the second assessment factor of the variability. In terms of aroma, honeys from Africa were characterized by smoky, resin, caramel and dried fruit as opposed to floral and fruity, mainly for honeys from South America and Europe. Finally, the honeys were ranked according to their sweetness. The second objective of this study was to test the new sensory method, called Pivot Profile(c) which is used to describe a large number of products with interpretable results. PMID- 29579930 TI - Antioxidative and antibacterial activities of aqueous ethanol extracts of berries, leaves, and branches of berry plants. AB - Phenolic compounds were extracted with food grade solvent of acidified aqueous ethanol from leaves, berries, berry press cakes, and branches of Finnish berry plants and analyzed with HPLC-DAD, UPLC-DAD-ESI-MS and NMR. In addition, press cakes from two berry species and branches from one species were also extracted and analyzed with the same methods. The antioxidant activities of the extracts were evaluated using Folin-Ciocalteau, oxygen radical absorbance capacity (ORAC), DPPH free radical scavenging, and total radical trapping antioxidant parameter (TRAP) assays. The antibacterial activities were investigated against various Gram-negative and Gram-positive foodborne pathogens. The leaf extracts showed higher antioxidative activities (3-20 fold in ORAC assay, 10-20 fold in TRAP) than the berry extracts, in association with the higher contents of phenolic compounds in the leaf extracts; Strongest anti-bacterial effects was observed in the leaf extracts of lingonberry (Vaccinium vitis-idaea), sea buckthorn (Hippophae rhamnoides ssp. rhamnoides) and saskatoon (Amelanchier alnifolia) on Staphylococcus aureus, Listeria monocytogenes, and Bacillus cereus. However, the antibacterial efficacy varied with bacterial species and strains. The Folin Ciocalteu, ORAC, and TRAP values was strongly correlated with the total content of flavonoids with less association shown with the content of total phenolics and flavonol glycosides. The results suggest a major contribution of pranthocyanidins and flavan-3-ols to the antioxidative activities of the extracts. The growth inhibition on Staphylococcus aureus and Bacillus cereus was clearly associated with the content of total phenolics and ellagitannins. PMID- 29579931 TI - Sensory profiling and quality assessment of research Cabernet Sauvignon and Chardonnay wines; quality discrimination depends on greater differences in multiple modalities. AB - The sensory profiles of Cabernet Sauvignon and Chardonnay research wines were determined and analysed together with wine quality scores of expert judges. Research Cabernet Sauvignon and Chardonnay wines from three and two vintages, respectively, were evaluated. Wines of both varieties were produced with grapes harvested from across South Australian wine making regions throughout 2013-2016 vintages. Wines within varieties were vinified identically across samples and also across vintages. Wines were profiled in triplicate using descriptive analysis with a panel of trained assessors (n=9-11) and graded for quality in triplicate by winemakers (n=6-9) using a sorting task based on similarity of quality and with the aid of definitions formed by the winemakers prior to sorting. The data sets were analysed using canonical variate analysis (CVA) and multidimensional scaling (MDS). The scores from CVA and MDS per variety per vintage were analysed using Generalised Procrustes Analysis (GPA). Differences in Cabernet Sauvignon samples by provenance were determined, where associations with regions by sensory attributes were observed in all vintages. These wines were consistently sorted based on quality by the winemakers, evident from GPA. Chardonnay in comparison were poorly discriminated in both sensory profiles and quality. The combination of descriptive sensory analysis with sorting was complimentary to each other and was able to uncover additional information about the sensory properties of wines when the two methods were used in concert, such as balance and complexity. However the red wine variety had more intrinsic characteristics that lead to better discrimination based on sensory properties and hence quality than the white wine variety. PMID- 29579932 TI - Multi-functional application of Moringa oleifera Lam. in nutrition and animal food products: A review. AB - Research on the use of various parts of the Moringa oleifera Lam. plant (M. oleifera) as a nutritional and neutraceutical resource for human and animal diets has increased in recent years, emanating from the widespread use of the plant in traditional cuisines and medicinal remedies in several regions of the world. Analytical studies have identified M. oleifera as an important source of essential nutrients; rich in protein, essential amino acids, minerals, and vitamins, with a relatively low amount of antinutrients. It is also a rich source of other bio active compounds including flavonoids and phenolic compounds; with several studies detailing demonstrated in vitro and in vivo functional properties, most substantially, antioxidant activities. Moringa oleifera consumption has been reported to improve the health status, feed conversion efficiency, growth performance and product quality of several livestock species, at dietary inclusion rates generally not exceeding 5% of total dry matter intake. Fortification of processed foods with M. oleifera has been reported to increase nutritional value, some organoleptic properties, oxidative stability and product shelf life; with a notable need for further analytical and consumer studies in the development of these products. There is a paucity of literature detailing clinical studies, nutrient bioavailability, toxicity and the mode of action of the bioactive compounds to which the health claims associated with M. oleifera consumption are attributed. Many of these are not yet fully understood; therefore more research in these areas is required in order to fully utilize the potential benefits of this plant in human and livestock nutrition. PMID- 29579933 TI - Portulaca oleracea extracts and their active compounds ameliorate inflammatory bowel diseases in vitro and in vivo by modulating TNF-alpha, IL-6 and IL-1beta signalling. AB - Portulaca oleracea L. (P. oleracea) is an herb that is widely used in traditional medicine to treat various diseases. However, its effects on inflammatory diseases, such as inflammatory bowel disease (IBD), are not yet well characterized. Here, we investigated the impact of the ethyl acetate (EtOAc) and ethanol (EtOH) extracts of P. oleracea on lipopolysaccharide (LPS)-induced inflammatory responses and phosphorylation of ERK, JNK, and p38 expression in RAW264.7 macrophages. In addition, the inhibitory effects of these extracts and fractions on 3% dextran sulphate sodium (DSS)-induced ulcerative colitis were examined using an ICR mouse model. DSS-induced colitis, including body weight loss, reduced colon length, and histological colon injury, was significantly ameliorated in mice fed the P. oleracea extracts (200 and 500mg/kg). In particular, P. oleracea extracts also inhibited pro-inflammatory cytokine (TNF alpha, IL-6, and 1L-1beta) production in mice with DSS-induced colitis; the P. oleracea extracts displayed higher and/or similar inhibitory activity to sulfasalazine at high concentrations. Furthermore, the chemical structures of active compounds separated from the EtOAc extract of P. oleracea were elucidated using nuclear magnetic resonance (NMR) spectroscopy (see Figure in supplementary materials), resulting in the identification of three known compounds. Among these active compounds, cis-N-feruloyl-3'-methoxytyramine (2) exhibited the strongest effects on preventing DSS-induced IBD in animal models. Thus, extract of P. oleracea and their active compounds represents a new therapeutic approach for patients with inflammatory bowel diseases. PMID- 29579934 TI - In vitro protein digestion of pork cuts differ with muscle type. AB - Porcine trapezius, longissimus dorsi and biceps femoris muscles have been shown to contain different types of muscle fibers. Little is known about the differences in digestibility among cooked pork cuts. In this study, we compared the protein losses of porcine trapezius, longissimus dorsi and biceps femoris muscles under in vitro digestion conditions. Meat samples were cooked in 72 degrees C water bath to center temperature of 70 degrees C. Then meat samples were homogenized and incubated with pepsin alone or followed by trypsin. The in vitro protein losses and particle size were measured. The pepsin and trypsin digestion products were separated and identified by SDS-PAGE and Nano LC-LTQ Orbitrap XL MS/MS. The results indicated that longissimus dorsi muscle had the highest losses under both pepsin and trypsin treatments (P<0.05). In untreated samples, biceps femoris muscle showed the greatest particle size (P<0.05), but enzymatic treatment decreased particles to the similar size for all the three muscles (P>0.05). Proteome analysis indicated that biceps femoris muscle had the highest susceptibility to digestion. Interaction analysis reveals that differential proteins mainly are related to glycolysis and muscle contraction. And thus fiber types could be the key factor to cause the differences in protein composition and their susceptibility to digestion. PMID- 29579935 TI - Characterization of oat beta-glucan and coenzyme Q10-loaded beta-glucan powders generated by the pressurized gas-expanded liquid (PGX) technology. AB - The physicochemical properties of the oat beta-glucan powder (BG) and coenzyme Q10 (CoQ10)-loaded BG powder (L-BG) produced by the pressurized gas-expanded liquid (PGX) technology were studied. Helium ion microscope, differential scanning calorimeter, X-ray diffractometer, AutoSorb iQ and rheometer were used to determine the particle morphology, thermal properties, crystallinity, surface area and viscosity, respectively. Both BG (7.7MUm) and L-BG (6.1MUm) were produced as micrometer-scale particles, while CoQ10 nanoparticles (92nm) were adsorbed on the porous structure of L-BG. CoQ10 was successfully loaded onto BG using the PGX process via adsorptive precipitation mainly in its amorphous form. Viscosity of BG and L-BG solutions (0.15%, 0.2%, 0.3% w/v) displayed Newtonian behavior with increasing shear rate but decreased with temperature. Detailed characterization of the physicochemical properties of combination ingredients like L-BG will lead to the development of novel functional food and natural health product applications. PMID- 29579936 TI - Effect of ultrasound on the physicochemical and microbiological characteristics of Italian salami. AB - Italian salami were sonicated in different times (0, 3, 6 and 9min) using ultrasound bath (US, 25kHz). The effect of sonication on microbial growth (lactic acid bacteria and Micrococcaceae), lipid and protein oxidation, total heme pigments (THP), non heme iron (NHI) and metmyoglobin (MMb) was investigated during processing (0, 2, 15, and 28days) and storage (1, 30, and 120days). US enhanced growth of microorganisms (P<0.05), mainly for the treatment 9min of sonication. The lipid (peroxide value and TBARS) and protein (thiol group) oxidative reactions were accelerated by US (P<0.05) and they should be considered to maintain Italian salami quality. Sonication contributed to maintenance of THP (P<0.05), especially during storage. MMb pigment was not affected by sonication (P>0.05). This study presented some features of US application that could be explored in the manufacture of Italian salami. PMID- 29579937 TI - Volatile changes in cv. Verdeal Transmontana olive oil: From the drupe to the table, including storage. AB - This study focused on the volatile changes in cv. Verdeal Transmontana throughout the entire olive oil processing chain, from the drupe to olive oil storage up to 12 months, while correlating it with quality parameters and sensory quality. During crushing and malaxation, the volatiles formed were mainly "green-leaf volatiles" (GLVs), namely (E)-2-hexenal, hexanal, and 1-hexanol. Centrifugation and clarification steps increased the total volatile amounts to 130 mg kg-1. However, clarification also increased nonanal and (E)-2-decenal contents, two markers of oxidation, with a noticeable loss of phenolic compounds and oxidative stability. During storage, the total volatile amounts reduced drastically (94% at 12 months after extraction), together with the positive sensory attributes fruity, green, bitter, and pungent. Despite being classified as extra-virgin after one year of storage, peroxides and conjugated dienes were significantly higher while there was a reduction in antioxidant capacity as well as in phenolic compounds (less 50%) and oxidative stability (57%). The present work allowed concluding that the extraction process modulates the volatile composition of olive oil, with a concentration of volatiles at the clarification step. During storage, volatiles are lost, mainly eight months after extraction, leading to the loss of important sensory attributes. PMID- 29579938 TI - Patterns of sweetness preference in red wine according to consumer characterisation. AB - The preference for sweet taste in red wine was examined according to consumer categories of age, gender, drinking experience and personality type (Big-5 personality-test). A total of 114 subjects revealed their preferences for sweetness after tasting dry red wine spiked with equal concentrations of glucose and fructose at 2g/L, 4g/L, 8g/L, 16g/L and 32g/L, following an ascending forced choice paired comparison method (2-AFC). The overall preference for sweetness was shown within the range of 4.8 to 21.9g/L, with maximal liking at 8g/L. Three patterns of response to sweetness were observed (sweet dislikers, sweet likers and indifferent to sweet) according to the different categories of consumers. Differences (p>0.05) were not found in sweetness preference among the categories up to 16g/L sugar except for the trait extraversion at 8g/L, where low extraverts showed a higher proportion of responses preferring the sweeter sample. Most significant differences were found only under the highest tasted concentration (32g/L). Females and novices preferred sweeter samples (p<0.05) when compared with the response of males and experienced consumers, respectively. PMID- 29579939 TI - Maltodextrin: A consummate carrier for spray-drying of xylooligosaccharides. AB - The aim of this study was to evaluate the influence of spray-drying on the powder qualities and microstructures of prebiotic xylooligosaccharides (XOS). The relationships between glass transition temperature (Tg) and XOS retention, moisture content, drying yield as well as specific surface area under different inlet air temperatures and maltodextrin concentrations were investigated. Antioxidant activity retention, hygroscopicity, color attributes, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) of the spray-dried XOS product were also assessed. The results indicated that an increase in inlet air temperature decreased the moisture content, hence the Tg value was increased. Higher maltodextrin concentration increased the Tg value, and was attributed to the molecular weight increase. The wall deposition was a tendency to occur when the temperature beyond the Tg, reduced the drying yield. Higher temperature and wall deposition promoted the decomposition of XOS into monosaccharide. The crust formation rate of droplets and stickiness of microparticles were affected by Tg, and hence, influenced the specific surface area. The antioxidant activity retention of XOS exhibited a concentration-dependent behavior. The hygroscopicity of the microparticles could be reduced by both of the low inlet air temperature and high maltodextrin concentration. According to the results of color attributes, XRD and SEM, the particles were colorless and amorphous, and tended to become more spherical and scattered with the addition of maltodextrin. The FT-IR analysis confirmed that no chemical reaction occurred between XOS and agent, which indicated that maltodextrin is a promising carrier for producing bioactive XOS powder. PMID- 29579940 TI - Impact of temperature, nutrients, pH and cold storage on the germination, growth and resistance of Bacillus cereus spores in egg white. AB - B. cereus spores are a concern to the food industry, especially to the producers of heat sensitive food products like egg white or precooked and stored food such as fried rice. This study investigated the impact of nutrients, temperature (4, 8, 15 and 25 degrees C), pH (4, 5, 7 and 9), and cold storage on the germination, growth and resistance of B. cereus spores. In egg white held at 4 degrees C for 12 days spore germination was not apparent, however the addition of egg yolk (5%) resulted in a 2 Log colony forming units (CFU)/mL increase in vegetative cells (p < .05). Adding l-alanine (0.9 mg/mL) to egg white did not induce germination unless the spores were simultaneously heat activated at 70 degrees C for 30 min. On incubation at 15 or 25 degrees C in egg white, spore germination increased by 3.0 Log and 3.7 Log CFU/mL on day 12. The presence of 5% yolk further enhanced germination and subsequent sporulation during storage at 15 and 25 degrees C. Acidification (pH 4) of 10% egg white solution prevented germination at 4, 8, 15 and 25 degrees C. Spores held at 4 degrees C for 6 days in phosphate buffer (50 mM, pH 4) had visible deformations on their surface (scanning electron microscopy) and a significant reduction in D88, and D92 values of 13.9 and 8.2 min respectively. A better understanding of how spores sense and respond to changing environmental conditions will help in the development of processing strategies, involving multiple hurdles to ensure the prevention of germination and subsequent toxin production. PMID- 29579942 TI - A novel antioxidative peptide derived from chicken blood corpuscle hydrolysate. AB - Chicken blood contains copious amounts of edible protein, which is currently underutilized. In this study, chicken blood corpuscle was hydrolyzed using two proteases (papain and flavourzyme) and its hydrolysis conditions were optimized by means of response surface methodology (RSM). The optimal conditions based on obtaining a hydrolysate with maximum antioxidant activity were E/S 2.0%, temperature 50 degrees C, and time 6.0h. Under the above conditions, the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, superoxide anion scavenging activity and reducing power of papain and flavourzyme hydrolysate (PFH) were 94.99+/-0.31%, 57.39+/-2.82%, and 1.83+/-0.06, respectively. Additionally, PFH showed not only a stable DPPH scavenging activity in the pH ranges of 1 to 7, but also a good tolerance to magnesium (Mg2+), potassium (K+) and calcium (Ca2+). We also found that PFH retained at least 95% of antioxidant capacity under simulated gastrointestinal digestion. Subsequently, PFH was purified sequentially by ultrafiltration, anion exchange chromatography, gel filtration chromatography, and high-performance liquid chromatography (HPLC). Finally, the sequence of the peptide with the highest antioxidant activity was identified to be AEDKKLIQ (943.5Da) using LC-ESI-MS/MS. Further, this peptide showed free radicals scavenging ability and reducing power as well as that of GSH (P>0.05), further evidencing its potential used as an antioxidative ingredient.

The aim of this work was to investigate the effects of endogenous proteins and lipids on starch digestibility in rice flour, with an emphasis on establishing the underlying physicochemical mechanisms involved. Native long grain indica rice flour and rice flour with the lipids and/or proteins removed were subjected to a simulated digestion in vitro. A significant increase in starch digestibility was observed after removal of proteins, lipids, or both. The starch digestibility of the rice flour without lipids was slightly lower than that without proteins, even though the proteins content was about 10-fold higher than the lipids content. Microstructural analysis suggested that the proteins and lipids were normally attached to the surfaces of the starch granules in the native rice flour, thus inhibiting their contact with digestive enzymes. Moreover, the proteins and lipids restricted the swelling of the starch granules, which may have decreased their digestion by reducing their surface areas. In addition, amylose-lipid complex was detected in the rice flour, which is also known to slow down starch digestion. These results have important implications for the design of foods with improved nutritional profiles.

AB - Edible insects are part of the diets of a significant proportion of rural populations in the tropics especially Africa and Asia, and their use as source of key nutrients for better nutrition is re-emerging. Indigenously, elemental methods are used to process the insects before they are consumed or sold in retail outlets. In recent years, better knowledge of processing, packaging and storage has become necessary because of commercialisation needs. A common processing approach involves drying after a brief heat-treatment step, and then milling into a powdered product which is sold to manufacturers or consumers as ingredient for processing final products. The hydration properties of dried powders of edible house cricket and black soldier fly larvae (BSFL) were studied with the aim of predicting shelf-life stability under typical packaging and storage temperatures experienced in the tropics. Moisture adsorption isotherms were determined gravimetrically at 25, 30 and 35 degrees C, over 0.11-0.97 water activity (aW) range, and the data fitted to various models. Sorption isotherms were of type II according to Brunauer classification indicating monolayer multilayer sorption behaviour. Cricket powder exhibited higher hydration capacity, and aW of this product was less sensitive to temperature variation as compared to BSFL powder. In the two products, water exhibited transitions from bound- to free- state at ~5 g/100 g moisture content. Based on Heiss-Eichner model, a shelf-life of 7 months at 25 degrees C can be achieved if the cricket and BSFL powders are dried to ca. 5 g/100 g moisture content and packaged in 80 MUm thick polyethylene films. At 35 degrees C the shelf-life of the cricket product is shortened three- to four-fold whereas the BSFL powder is unable to store.

AB - Black garlic is a distinctive garlic deep-processed product made from fresh garlic at high temperature and controlled humidity. To explore microbial community structure, diversity and metabolic potential during the 12days of the black garlic processing, Illumina MiSeq sequencing technology was performed to sequence the 16S rRNA V3-V4 hypervariable region of bacteria. A total of 677,917 high quality reads were yielded with an average read length of 416bp. Operational taxonomic units (OTU) clustering analysis showed that the number of species OTUs ranged from 148 to 1974, with alpha diversity increasing remarkably, indicating the high microbial community abundance and diversity. Taxonomic analysis indicated that bacterial community was classified into 45 phyla and 1125 distinct genera, and the microbiome of black garlic samples based on phylogenetic analysis was dominated by distinct populations of four genera: Thermus, Corynebacterium, Streptococcus and Brevundimonas. The metabolic pathways were predicted for 16S rRNA marker gene sequences based on Kyoto Encyclopedia of Genes and Genomes (KEGG), indicating that amino acid metabolism, carbohydrate metabolism and membrane transport were important for the black garlic fermentation process. Overall, the study was the first to reveal microbial community structure and speculate the composition of functional genes in black garlic samples. The results contributed to further analysis of the interaction between microbial community and black garlic components at different stages, which was of great significance to study the formation mechanism and quality improvement of black garlic in the future.

AB - The influence of carrier oil type on the chemical stability, antioxidant properties and bioaccessibility of lycopene in orange oil-in-water beverage emulsions was investigated. The emulsions were formulated with orange oil (A), which was partially (50%) replaced with tributyrin (B) or corn oil (C) because of their distinctively different fatty acid composition. The addition of corn oil enhanced the physical stability of the beverage during chilled storage by inhibiting Ostwald ripening. The formation of oxidation products was insignificant after storage for 28 days at 4 degrees C, regardless the type of added oil. Lycopene was more susceptible to chemical degradation in the presence of unsaturated, long chain triglycerides and the retention followed the order: A (87.94%), B (64.41%) and C (57.39%). Interestingly, bioaccessibility of lycopene was significantly lower for emulsions formulated with 50% corn oil as opposed to 100% orange oil as indicated by the simulated in vitro gastric digestion model. PMID- 29579946 TI - Comparative study on the composition of free amino acids and derivatives in the two botanical origins of an edible Chinese herb "Xiebai", i.e., Allium chinense G. Don and Allium macrostemon Bunge species. AB - Xiebai is an edible Chinese herb with various health and therapeutic benefits. To evaluate its nutritional and health values, the free amino acids and derivatives of its two botanical origins (i.e., Allium chinense G. Don and Allium macrostemon Bunge) were isolated using a solvent extraction method and analyzed using automatic amino acid analysis and ultra-performance liquid chromatography quadrupole-time of flight (UPLC-Q-TOF) mass spectrometry. Our data show that both plants contain abundant free amino acids, and the amount of total free amino acids in A. chinense G. Don is higher than that in A. macrostemon Bunge. The free amino acid compositions in the two plants are qualitatively similar, including nineteen proteinogenic and four non-proteinogenic amino acids. The identified proteinogenic amino acids include eight essential amino acids and five semi essential amino acids. The sum of essential and semi-essential amino acids accounts for 64.9% and 69.7% of the total free amino acids of the two plants, respectively. The principal amino acids of both plants, from highest concentration to lowest concentration, are arginine, glutamine, glutamic acid, asparagine and serine. A. chinense G. Don is also rich in citrulline and lysine. In addition, two amino acid derivatives were identified from the two plants, i.e., the proline analog N-methyl-proline and the dipeptide H-Glu-Tyr-OH. For the first time, the presence of N-methyl-proline in the plants of the Allium genus and the presence of H-Glu-Tyr-OH in unprocessed food sources are reported. The influences of the identified substances on the flavor, nutrition and health values of Xiebai are discussed. PMID- 29579947 TI - Sensory description of marine oils through development of a sensory wheel and vocabulary. AB - The Omega-3 industry lacks a defined methodology and a vocabulary for evaluating the sensory quality of marine oils. This study was conducted to identify the sensory descriptors of marine oils and organize them in a sensory wheel for use as a tool in quality assessment. Samples of marine oils were collected from six of the largest producers of omega-3 products in Norway. The oils were selected to cover as much variation in sensory characteristics as possible, i.e. oils with different fatty acid content originating from different species. Oils were evaluated by six industry expert panels and one trained sensory panel to build up a vocabulary through a series of language sessions. A total of 184 aroma (odor by nose), flavor, taste and mouthfeel descriptors were generated. A sensory wheel based on 60 selected descriptors grouped together in 21 defined categories was created to form a graphical presentation of the sensory vocabulary. A selection of the oil samples was also evaluated by a trained sensory panel using descriptive analysis. Chemical analysis showed a positive correlation between primary and secondary oxidation products and sensory properties such as rancidity, chemical flavor and process flavor and a negative correlation between primary oxidation products and acidic. This research is a first step towards the broader objective of standardizing the sensory terminology related to marine oils. PMID- 29579948 TI - Multiple protective effect of peptides released from Olea europaea and Prunus persica seeds against oxidative damage and cancer cell proliferation. AB - The long exposition to reactive species results in oxidative stress which has been related with the development of cancer and other serious diseases. Olea europaea and Prunus persica seeds present a high protein content and preliminary results demonstrated their high potency to obtain bioactive peptides. The protective effect against oxidative damage exerted by peptides released from Olea europaea and Prunus persica seeds has been evaluated in this work. Seed hydrolysates showed protection against oxidation through four different mechanisms: inhibition of the formation of hydroxyl radicals, scavenging of free radicals, reduction of oxidizing compounds, and inhibition of lipid peroxidation. Moreover, seed hydrolysates also reduced the oxidative stress induced by an oxidizing agent on human cancer cells. Despite protection evaluated by individual mechanisms seemed to be significantly affected by the seed genotype, overall protection of seed hydrolysates was not so different. Seeds hydrolysates were not cytotoxic on normal cells but they demonstrated antiproliferative effect on human cancer cells (HeLa, PC-3, and HT-29). Peptides in all seed hydrolysates were sequenced by RP-HPLC-ESI-Q-TOF. Eighteen common peptides were observed among olive seed hydrolysates while a wider variability was observed among Prunus seed hydrolysates. PMID- 29579950 TI - Hydrolysis and transepithelial transport of two corn gluten derived bioactive peptides in human Caco-2 cell monolayers. AB - The objective of this paper was to investigate the transepithelial transport of two novel corn gluten-derived antioxidant peptides, YFCLT and GLLLPH, using Caco 2 cell monolayers. Results showed that both of YFCLT and GLLLPH could transport in intact form across Caco-2 cell monolayers with apparent permeability coefficient (Papp) values of (1.10+/-0.16)*10-7cm/s and (1.98+/-0.23)*10-7cm/s, respectively. However, it was found that the two peptides were susceptible and easily hydrolyzed by brush border membrane peptidases. In the presence of diprotin A, an inhibitor of dipeptidyl peptidase IV (DPPIV), the hydrolysis of YFCLT and GLLLPH decreased and their permeabilities increased significantly compared to control group (P<0.05). The results of transport routes revealed that Gly-Sar, a peptide transporter 1 (PepT1) substrate, had little effects on the transepithelial permeability (P>0.05), suggesting that the transport of YFCLT and GLLLPH across Caco-2 cell monolayers was not mediated by PepT1. However, it was found that cytochalasin d, a tight junctions (TJs) disruptor, increased the permeability significantly (P<0.05). While wortmannin, a transcytosis inhibitor, and sodium azide, an ATP synthesis inhibitor, both decreased the permeability significantly (P<0.05). It indicated that the TJs-mediated paracellular pathway and energy-dependent transcytosis were involved in the transport of YFCLT and GLLLPH across Caco-2 cell monolayers. PMID- 29579949 TI - Microbiological criteria and ecology of commercially available processed cheeses according to the product specification and physicochemical characteristics. AB - Although global cheese manufacturers release a variety of products onto the market, research on the microbiological quality and safety of cheese has focused mainly on conventional cheeses made from milk. Here, this study aimed to investigate commercially processed cheese products produced by mixing conventional cheeses after melting. Two approaches were used: a summary and comparison of legal definitions and standards/regulations regarding the microbiological criteria used by major cheese traders in the global market (Australia/New Zealand, China, European Union, Japan, Mexico, Republic of Korea, and the United States) and a comprehensive microbiological analysis of commercial products (n = 800), along with an assessment of salinity, pH, water activity, and heating conditions. The results of the literature search showed that major importing countries (China, Japan, Mexico, and the Republic of Korea) have stricter microbiological criteria for commercially available cheese products than major exporters (Australia/New Zealand, EU, and the USA). The former set limits with respect to the number of total coliforms in the product. Microbiological analyses were designed according to global standards and recommendations. No test sample contained detectable levels of Clostridium perfringens, enterohemorrhagic Escherichia coli, Listeria monocytogenes, Salmonella, or Staphylococcus aureus. In addition, no coliform bacteria (including E. coli) were detected. Overall, 79.9% of the samples contained detectable aerobic plate counts (1.0-7.8 log CFU/g); these levels varied significantly according to product type (grated cheese > chunks; cream cheese > portions or sliced) (p < .05). There was no significant association between microbe levels and salinity, water activity, pH, and heating conditions. The results can be used to develop a comprehensive database about commercially processed cheese products available in the global market and, as such, may be helpful for both national authorities and cheese manufacturers when considering novel strategic management plans for microbiological quality and safety. PMID- 29579951 TI - Stability of functional compounds and antioxidant activity of fresh and pasteurized orange passion fruit (Passiflora caerulea) during cold storage. AB - This research aimed to evaluate differences in the stability of physicochemical and color parameters, phenolic compounds, flavonoids, carotenoids and antioxidant capacity in fresh and pasteurized juice of orange passion fruit, respectively cold stored (8 degrees C) during 0-4 or during 0-15 days. The results showed that in the physicochemical analysis, no significant differences were observed comparing pasteurized and fresh juice during storage. The pasteurized juice showed higher concentrations of color parameters, phenolic compounds (15% more of retention for days 0 and 4), epigallocatechin gallate (40% in day 0 and 27% in day 4), lycopene (142% for day 0 and 39% for day 4), total carotenoids (114% in day 0 and 8% in day 4) and antioxidant capacity (12% in day 0 and 7% in day 4).; already fresh juice retained more values of quercetin (79% in day 0 and 245% in day 4), alpha-carotene (57% in day 4), beta-carotene and provitamin A (80% of retention in day 4). Therefore, the pasteurization processing was positive in orange passion fruit juice and improved the accessibility of most bioactive compounds. PMID- 29579952 TI - High pressure homogenization combined with pH shift treatment: A process to produce physically and oxidatively stable hemp milk. AB - Hemp milk, an emerging beverage with high nutritional value and low allergenicity, is an attractive alternative to dairy, soy, and nut milks. To obtain a non-thermally processed, physically and oxidatively stable hemp milk, high pressure homogenization (HPH) combined with pH shift treatment was investigated. For hemp milk (4% protein, 5% fat) without pH shift, increasing the homogenization pressure (up to 60 MPa) resulted in a more uniform distribution of emulsion droplets (2.2-2.7 MUm). When pH shift was applied prior to HPH, large clusters and aggregates of oil droplets (3.5-8.2 MUm) were formed. Interestingly, hemp milk with such interactive structures was remarkably stable, showing negligible phase separation within 3-day storage at 4 degrees C. Moreover, hemp milk made by combined pH shift and HPH exhibited delayed hydroperoxides (expressed as peroxide value, PV) and malondialdehyde (expressed as thiobarbituric acid-reactive substances, TBARS) production, suggesting the resistance of such emulsion cluster structures to radicals. On the other hand, a significant reduction of microbial population was observed in hemp milk prepared by pH shift combined with HPH. The results indicate that the pH shift + HPH combination treatment may potentially be employed for the production of non thermally processed hemp milk. PMID- 29579953 TI - Effects of the gastric juice injection pattern and contraction frequency on the digestibility of casein powder suspensions in an in vitro dynamic rat stomach made with a 3D printed model. AB - Previously, we have prepared a version of the dynamic in vitro rat stomach system (DIVRS-II or Biomimic Rat II). It was constructed and tested by showing similar digestive behaviors with those occurred in vivo. In the present work, a 3D printed plastic mold was employed to create highly repeatable silicone rat stomach model. It has been seen to have shortened the time to handcraft a model like that used in DIVRS-II. The maximum mechanical force of the current stomach model generated by rolling extrusion is found to be more stable probably due to the more uniform wall thickness of the new model. Then the effects of the simulated gastric secretion patterns and contraction frequency of the system on the in vitro digestibility of casein powder suspensions were investigated. The results have shown that the location of the gastric secretion injection has an impact on experimental digestibility. The position of rolling-extrusion area, established at the central part of glandular portion (stomach B), displayed the highest digestibility compared to that at the other locations. Furthermore, the extent of digestion was positively correlated with the contraction frequency of the model stomach system, with the maximum frequency of 12cpm giving the highest digestibility. This highest digestibility is almost the same as the average value found in vivo. The better digestive performance produced by optimizing the gastric secretion pattern and contraction frequency may be both resulted from the improved mixing efficiency of the food matrix with digestive juice. This study shows that it is possible to achieve what in vivo in a simulated digestion device, which may be used for future food and nutrition studies in vitro. PMID- 29579954 TI - Effect of household cooking techniques on the microbiological load and the nutritional quality of mealworms (Tenebrio molitor L. 1758). AB - Mealworms are new food products in Europe, but consumers do not know how to cook them. Although cooking could increase the safety, acceptability, palatability, and digestibility of insects, the heating process could have deleterious effects on protein and lipid quality. Therefore, this study characterized the effects of different household cooking methods (boiling, pan-frying, vacuum cooking, and oven cooking) on the microbial load and nutritive value of mealworms, with a focus on protein digestibility and fatty acid composition. Boiling and cooking under vacuum were the most efficient techniques to reduce microbial load while maintaining the high levels of protein and polyunsaturated fatty acids of mealworms. Cooking method-related changes were very low on macronutrients content except for pan-fried mealworms which exhibited the highest lipid content. Cooking slightly changed fatty acid composition of mealworms by principally decreasing their level of saturated fatty acids but also increased the in vitro crude protein digestibility of mealworms. PMID- 29579955 TI - Improving microbiological safety and quality characteristics of wheat and barley by high voltage atmospheric cold plasma closed processing. AB - Contamination of cereal grains as a key global food resource with insects or microorganisms is a persistent concern for the grain industry due to irreversible damage to quality and safety characteristics and economic losses. Atmospheric cold plasma presents an alternative to conventional grain decontamination methods owing to the high antimicrobial potential of reactive species generated during the treatment, but effects against product specific microflora are required to understand how to optimally develop this approach for grains. This work investigated the influence of ACP processing parameters for both cereal grain decontamination and grain quality as important criteria for grain or seed use. A high voltage (HV) (80 kV) dielectric barrier discharge (DBD) closed system was used to assess the potential for control of native microflora and pathogenic bacterial and fungal challenge microorganisms, in tandem with effects on grain functional properties. Response surface modelling of experimental data probed the key factors in relation to microbial control and seed germination promotion. The maximal reductions of barley background microbiota were 2.4 and 2.1 log10 CFU/g and of wheat - 1.5 and 2.5 log10 CFU/g for bacteria and fungi, respectively, which required direct treatment for 20 min followed by a 24 h sealed post treatment retention time. In the case of challenge organisms inoculated on barley grains, the highest resistance was observed for Bacillus atrophaeus endospores, which, regardless of retention time, were maximally reduced by 2.4 log10 CFU/g after 20 min of direct treatment. The efficacy of the plasma treatment against selected microorganisms decreased in the following order: E. coli > P. verrucosum (spores) > B. atrophaeus (vegetative cells) > B. atrophaeus (endospores). The challenge microorganisms were more susceptible to ACP treatment than naturally present background microbiota. No major effect of short term plasma treatment on the retention of quality parameters was observed. Germination percentage measured after 7 days cultivation was similar for samples treated for up to 5 min, but this was decreased after 20 min of direct treatment. Overall, ACP proved effective for cereal grain decontamination, but it is noted that the diverse native micro-flora may pose greater resistance to the closed, surface decontamination approach than the individual fungal or bacterial challenges, which warrants investigation of grain microbiome responses to ACP. PMID- 29579956 TI - Mechanistic insight into softening of Canadian wonder common beans (Phaseolus vulgaris) during cooking. AB - The relative contributions of cotyledons and seed coats towards hardening of common beans (Phaseolus vulgaris) were investigated and the rate-limiting process which controls bean softening during cooking was determined. Fresh or aged whole beans and cotyledons were soaked and cooked in demineralised water or 0.1 M NaHCO3 solution, and texture evolution, microstructure changes and thermal properties were studied. Fresh and aged whole beans cooked in demineralised water had significantly different softening rate constants and so did fresh and aged cotyledons. The comparable softening rate constants of aged whole beans and cotyledons indicated an insignificant role of the seed coat in hardening during storage. All samples cooked faster in 0.1 M NaHCO3 solution. Disintegration of cooked tissues followed by microscopic examination revealed a transition from cell breakage through a phase of cell breakage and separation to complete cell separation with increased cooking time wherefore texture decayed. Therefore, progressive solubilization of pectin in the middle lamella greatly promoted texture decay. While residual birefringence even after substantial cooking time suggested some molecular order of the starch, calorimetric analyses revealed complete starch gelatinisation before complete cell separation occurred. This implies an insignificant role of starch in texture decay during cooking but its hindered uncoiling into a viscous gel after gelatinisation due to the restricting cell wall could promote its retrogradation. Therefore, we suggest that the rate determining process in bean softening relates to cell wall/middle lamella changes influencing pectin solubilization. PMID- 29579957 TI - The role of product information on consumer sensory evaluation, expectations, experiences and emotions of cricket-flour-containing buns. AB - Studies suggest that consumer' acceptance of edible insects can be enhanced by processing and blending them with familiar food products. This is however, expected to result in changes in some sensory attributes. In this study, we investigated how consumers evaluate the appropriateness of sensory attributes of a common bakery product (buns) that was blended with cricket-flour i.e., cricket flour-containing (CFC) buns. We also tested whether provision of information can modulate the sensory evaluations, personal involvement and emotions. The study is based on a field experiment involving 432 participants drawn from rural communities in Kenya. Participants were randomly assigned to 3 information treatment groups: i) Control group - received only general information, ii) Treatment 1 - received general information and information about the benefits (i.e., positive attributes), iii) Treatment 2 - received general information and information about the potential drawbacks (i.e., negative attributes). Participants evaluated the CFC buns before and after tasting using Just-About Right (JAR) scale. Results indicate that providing product information affected sensory evaluation of the product's sensory attributes. They also indicate that actual tasting of the CFC buns improved the convergence of sensory evaluation of the attributes towards the ideal level. Results further show that CFC buns elicited more positive feelings with little differences in the emotional profiles between the information treatments, which suggests general interest in the buns. These results provide useful insights on how to enhance consumer acceptance of insect-based foods. We discuss the implications of the findings.

AB - The aim of this study was to develop and validate an HPLC-DAD method to evaluate the phenolic compounds profile of organic and conventional Pera-Rio orange juice. The proposed method was validated for 10 flavonoids and 6 phenolic acids. A wide linear range (0.01-223.4MUg.g-1), good accuracy (79.5-129.2%) and precision (CV<=3.8%), low limits of detection (1-22ng.g-1) and quantification (0.7-7.4MUg), and overall ruggedness were attained. Good recovery was achieved for all phenolic compounds after extraction and cleanup. The method was applied to organic and conventional Pera-Rio orange juices from beginning, middle and end of the 2016 harvest. Flavones rutin, nobiletin and tangeretin, and flavanones hesperidin, narirutin and eriocitrin were identified and quantified in all organic and conventional juices. Identity was confirmed by mass spectrometry. Nineteen non identified phenolic compounds were quantified based on DAD spectra characteristic of the chemical class: 7 cinnamic acid derivatives, 6 flavanones and 6 flavones. The phenolic compounds profile of Pera-Rio orange juices changed during the harvest; levels increased in organic orange juices, and decreased or were about the same in conventional orange juices. Phenolic compounds levels were higher in organic (0.5-1143.7mg.100g-1) than in conventional orange juices (0.5 689.7mg.100g-1). PCA differentiated organic from conventional FS and NFC juices, and conventional FCOJ from conventional FS and NFC juices, thus differentiating cultivation and processing.

AB - Acai berry is the fruit of an Amazonian palm tree and rich in anthocyanins (ACNs). Scientific studies have proven the health benefits of acai berry and declared this fruit as "super fruit". ACNs have high antioxidant activities, but they are unstable and can easily deteriorate during food processing. In order to protect ACNs and increase their applicability, food-grade water-in-oil (W/O) emulsions were successfully formulated with different concentrations of acai berry extracts (AEs). The formulated W/O nanoemulsions were relatively stable, with no phase separation after 30 days of storage. The average droplet size varied between 146.8 and 814.8 nm, with higher values corresponding to samples without AEs. All W/O nanoemulsion samples exhibited antioxidant activity and high retention rates of polyphenols after 30 days of storage. ACN retention followed first-order kinetics, with high protection of ACNs observed in emulsified samples. 2% AE encapsulated in a 30 wt% W/O nanoemulsion had an estimated half life of 385 days. The results indicate that stable nanoemulsion systems with high ACN protection can be produced with possible applications in the food and pharmaceutical industries.

Koch] extracts. AB - Ultrasonic-assisted extraction combined with statistical tools (factorial design, response surface methodology and kinetics) were used to evaluate the effects of the experimental conditions of temperature, solid-to-solvent ratio, ethanol concentration and time for the extraction of the total phenolic content from pecan nut shells. The optimal conditions for the aqueous and hydroalcoholic extract (with 20% v/v of ethanol) were 60 and 80 degrees C; solid to solvent ratio of 30 mL.g-1 (for both) and extraction time of 35 and 25 min, respectively. Using these optimize extraction conditions, 426 and 582 mg GAE.g-1 of phenolic compounds, from the aqueous and hydroalcoholic phases respectively, were obtained. In addition, the analysis of the phenolic compounds using the LC-ESI MS/MS system allowed the identification of 29 phenolic compounds, 24 of which had not been reported in literature for this raw material yet. PMID- 29579961 TI - Evaluation of the neuroprotective and antidiabetic potential of phenol-rich extracts from virgin olive oils by in vitro assays. AB - In this work, phenol-rich extracts from 'Cornicabra' and 'Picual' virgin-olive oils (EVOOs) were examined, for the first time, to establish their capacity to inhibit key enzymes involved in Alzheimer's disease (AD) (acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and 5-lipoxygenase (LOX)), major depressive disorder (MDD) and Parkinson's disease (PD) (monoamine oxidases: hMAO-A and hMAO B respectively), and diabetes mellitus (DM) (alpha-glucosidase and alpha amylase). 'Cornicabra' displayed the best inhibitory activity against all enzymes, when compared to 'Picual': BuChE (IC50 = 156 +/- 4 and 308 +/- 33 mg mL 1), LOX (IC50 = 26 +/- 0.5 and 37 +/- 3 mg mL-1), hMAO-A (IC50 = 20 +/- 2 and 37 +/- 0.2 mg mL-1), hMAO-B (IC50 = 131 +/- 7 and 215 +/- 13 mg mL-1) and alpha glucosidase (IC50 = 154 +/- 17 and 251 +/- 31 mg mL-1), respectively. The behaviour observed can be associated with the higher content of secoiridoids, lignans and phenolic acids in 'Cornicabra' EVOO. PMID- 29579962 TI - The effect of prefermentative addition of gallic acid and ellagic acid on the red wine color, copigmentation and phenolic profiles during wine aging. AB - : Though non-anthocyanin phenolics normally do not have red color, they affect the red color expression in the copigmentation of red wines. In this study, the influence of prefermentative addition of 300mg/L gallic acid and ellagic acid, as cofactors, on aging dry red wines had been systematically evaluated at the industrial scales from the perspectives of color, phenolic profiles and copigmentation effects of anthocyanins. Red wines made with these two compounds exhibited better color properties than the control, having better CIELAB chromatic parameters. Additionally, significantly higher levels of detectable anthocyanins and copigmented anthocyanin ratio had been observed. Wines with ellagic acid showed better chromatic properties and phenolic profiles than wines with gallic acid, as shown in previous theoretical results. Anti-copigmentation phenomenon was noticed and elucidated. These practical results confirmed that ellagic acid was the better cofactor, and would give more additional guidance for the production of high quality wine.

AB - The low operating temperatures employed in atmospheric freeze-drying permits an effective drying of heat sensitive products, without any impairment of their quality attributes. When using power ultrasound, the drying rate can be increased, thus reducing the process duration. However, ultrasound can also affect the product quality. The aim of this study was to evaluate the effect of various drying process variables, namely air temperature and velocity, ultrasound power and sample size, on the antioxidant properties of eggplant (Solanum melongena L.) samples. For this reason, drying experiments were carried out at different drying temperatures (-5, -7.5, -10 degrees C), power ultrasound levels (0, 25, 50 W; 21.9 kHz) and air velocities (2, 5 m s-1) using different sample sizes (8.8 mm and 17.6 mm cube side). The ascorbic acid content (Jagota and Dani method), total phenolic content (Folin-Ciocalteau method), and the antioxidant capacity (FRAP method) of the dried products were considered as quality indicators of the dried samples. The increase in air velocity and temperature, as well as the sample size, significantly reduced the antioxidant potential of the dried samples (p-value < .05). For a given sample size, the application of ultrasound, at the acoustic power levels tested, did not produce significant effects on the antioxidant indicators considered. Temperature measurements inside the drying sample showed a non-negligible temperature rise when acoustic power was applied.

AB - As a protein-rich, underutilized crop, green soybean could be exploited to produce hydrolysates containing angiotensin-I converting enzyme (ACE) inhibitory peptides. Defatted green soybean was hydrolyzed using four different food-grade proteases (Alcalase, Papain, Flavourzyme and Bromelain) and their ACE inhibitory activities were evaluated. The Alcalase-generated green soybean hydrolysate showed the highest ACE inhibitory activity (IC50: 0.14 mg/mL at 6 h hydrolysis time) followed by Papain (IC50: 0.20 mg/mL at 5 h hydrolysis time), Bromelain (IC50: 0.36 mg/mL at 6 h hydrolysis time) and Flavourzyme (IC50: 1.14 mg/mL at 6 h hydrolysis time) hydrolysates. The Alcalase-generated hydrolysate was profiled based on its hydrophobicity and isoelectric point using reversed phase high performance liquid chromatography (RP-HPLC) and isoelectric point focusing (IEF) fractionators. The Alcalase-generated green soybean hydrolysate comprising of peptides EAQRLLF, PSLRSYLAE, PDRSIHGRQLAE, FITAFR and RGQVLS, revealed the highest ACE inhibitory activity of 94.19%, 99.31%, 92.92%, 101.51% and 90.40%, respectively, while their IC50 values were 878 MUM, 532 MUM, 1552 MUM, 1342 MUM and 993 MUM, respectively. It can be concluded that Alcalase-digested green soybean hydrolysates could be exploited as a source of peptides to be incorporated into functional foods with antihypertensive activity. PMID- 29579965 TI - Atlantic salmon (Salmo salar) co-product-derived protein hydrolysates: A source of antidiabetic peptides. AB - Large quantities of low-value protein rich co-products, such as salmon skin and trimmings, are generated annually. These co-products can be upgraded to high value functional ingredients. The aim of this study was to assess the antidiabetic potential of salmon skin gelatin and trimmings-derived protein hydrolysates in vitro. The gelatin hydrolysate generated with Alcalase 2.4L and Flavourzyme 500L exhibited significantly higher (p < 0.001) insulin and GLP-1 secretory activity from pancreatic BRIN-BD11 and enteroendocrine GLUTag cells, respectively, when tested at 2.5 mg/mL compared to hydrolysates generated with Alcalase 2.4L or Promod 144MG. The gelatin hydrolysate generated with Alcalase 2.4L and Flavourzyme 500L showed significantly more potent (p < 0.01) DPP-IV inhibitory activity than those generated with Alcalase 2.4L or Promod 144MG. No significant difference was observed in the insulinotropic activity mediated by any of the trimmings-derived hydrolysates when tested at 2.5 mg/mL. However, the trimmings hydrolysate generated with Alcalase 2.4L and Flavourzyme 500L exhibited significantly higher DPP-IV inhibitory (p < 0.05:Alcalase 2.4L and p < 0.01:Promod 144MG) and GLP-1 (p < 0.001, 2.5 mg/mL) secretory activity than those generated with Alcalase 2.4L or Promod 144MG. The salmon trimmings hydrolysate generated with Alcalase 2.4L and Flavourzyme 500L when subjected to simulated gastrointestinal digestion (SGID) was shown to retain its GLP-1 secretory and DPP IV inhibitory activities, in addition to improving its insulin secretory activity. However, the gelatin hydrolysate generated with Alcalase 2.4L and Flavourzyme 500L was shown to lose GLP-1 secretory activity following SGID. A significant increase in membrane potential (p < 0.001) and intracellular calcium (p < 0.001) by both co-product hydrolysates generated with Alcalase 2.4L and Flavourzyme 500L suggest that both hydrolysates mediate their insulinotropic activity through the KATP channel-dependent pathway. Additionally, by stimulating a significant increase in intracellular cAMP release (p < 0.05) it is likely that the trimmings-derived hydrolysate may also mediate insulin secretion through the protein kinase A pathway. The results presented herein demonstrate that salmon co product hydrolysates exhibit promising in vitro antidiabetic activity. PMID- 29579966 TI - The impact of newly produced protein and dietary fiber rich fractions of yellow pea (Pisum sativum L.) on the structure and mechanical properties of pasta-like sheets. AB - Two fractions from pea (Pisum sativum L.), protein isolate (PPI) and dietary fiber (PF), were newly produced by extraction-fractionation method and characterized in terms of particle size distribution and structural morphology using SEM. The newly produced PPI and PF fractions were processed into pasta-like sheets with varying protein to fiber ratios (100/0, 90/10, 80/20, 70/30 and 50/50, respectively) using high temperature compression molding. We studied protein polymerization, molecular structure and protein-fiber interactions, as well as mechanical performance and cooking characteristics of processed PPI-PF blends. Bi-modal particle size distribution and chemical composition of the PPI and PF fractions influenced significantly the physicochemical properties of the pasta-like sheets. Polymerization was most pronounced for the 100 PPI, 90/10 and 80/20 PPI-PF samples as studied by SE-HPLC, and polymerization decreased with addition of the PF fraction. The mechanical properties, as strength and extensibility, were likewise the highest for the 100 PPI and 90/10 PPI-PF blends, while the E-modulus was similar for all the studied blends (around 38 MPa). The extensibility decreased with the increasing amount of PF in the blend. The highest amounts of beta-sheets were found in the pasta-like sheets with high amounts of PPI (100, 90 and 80%), by FT-IR. An increase in PF fraction in the blend, resulted into the high amounts of unordered structures as observed by FT IR, as well as in an increase in the molecular scattering distances observed by SAXS. The water uptake increased and cooking loss decreased with increased proportions of the PF fraction, and the consistency of 10 min cooked pasta-like sheets were alike al dente texture. The new knowledge obtained in this study on the use of extraction-fractionation method to produce novel PPI and PF fractions for developing innovative high nutritious food can be of a great importance. The obtained knowledge on the pea protein and fiber processing behaviour could greatly contribute to a better control of functional properties of various temperature-processed products from yellow pea.

AB - The complexation of anthocyanin-rich black rice extracts (ARBRE) with soybean protein isolate (SPI) heated at 0, 70, 85, and 100 degrees C and its effect on protein digestibility were studied. The structural changes of SPI during its interaction with ARBRE in all the samples were studied by Fourier transform infrared, circular dichroism, and fluorescence spectroscopy. The secondary structure changes of SPI in all the samples after complexation with ARBRE showed a significant increase in alpha-helix and a significant decrease in beta-sheet contents. Results also showed that ARBRE quenched the SPI fluorescence (in both unheated and heated samples) via static quenching with a single binding site. The digestibility of unheated and heated SPI was improved upon complexing with ARBRE. The formation of the SPI-ARBRE complexes is beneficial for the application of soy protein-based products in foods by increasing their protein digestibility and nutritional quality. PMID- 29579968 TI - The regulation mechanisms of soluble starch and glycerol for production of azaphilone pigments in Monascus purpureus FAFU618 as revealed by comparative proteomic and transcriptional analyses. AB - Monascus spp. have been used for thousands of years as a traditional food additive in China. This mold can produce many different types of commercially valuable secondary metabolites of biological activity. Soluble starch and glycerol are the two principal carbon sources universally utilized by Monascus for the production of beneficial metabolites. In this study, the effects and regulation mechanisms of soluble starch and glycerol for M. purpureus FAFU618 on Monascus azaphilone pigments (MonAzPs) were investigated through ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-QTOF-MS/MS), comparative proteomics and quantitative real-time reverse transcription polymerase chain reaction (RT-qPCR). The production of intracellular and extracellular pigments was significantly different between the soluble starch group (SSG) and glycerol group (GCG). Additionally, the components of intracellular pigments revealed by UPLC-QTOF-MS/MS showed that Monascin and Ankaflavin increased significantly in the GCG, while Rubropunctatin and Monascorubrin increased in the SSG. Differentially expressed proteins of mycelia between SSG and GCG were analyzed by two-dimensional gel electrophoresis (2-DE) and MALDI-TOF/TOF MS. We identified 27 proteins with statistically altered expression, of which 18 proteins associated with the EMP (glycolytic pathway), translation, energy generation, proteolysis, etc. were up-regulated, and 9 proteins, including ribosomal proteins, heat shock proteins (HSPs) and others, were down-regulated in GCG. Meanwhile, the expression levels of MonAzP biosynthetic genes were also analyzed by RT-qPCR, and the results showed that mppA, mppC, mppR1 and mppR2 were down-regulated, whereas genes MpPKS5, MpFasA2, MpFasB2, mppB, mppD and mppE were up-regulated. Collectively, these findings illustrate that the regulation of MonAzPs is not only closely related to the expression levels of certain proteins in the polyketide synthesis pathway but also closely related to the concentration of primary metabolism-generated molecules that are used as substrates for polyketide synthesis. The present study provides insights into the regulation of different carbon sources on the metabolism of MonAzPs in M. purpureus FAFU618. These results may promote further development of functional foods or medicines from Monascus spp. fermented products. PMID- 29579969 TI - De-stoning technology for improving olive oil nutritional and sensory features: The right idea at the wrong time. AB - De-stoning technology has been introduced in the olive oil sector more than twenty years ago. It has not gained momentum because, sometimes, innovative ideas are not accepted since they are suggested at the wrong time or under the wrong circumstances. Virgin olive oil (VOO) is one of the most popular functional foods, mainly due to its antioxidant properties. These features, as well as other nutritional characteristics are generally enhanced by the de-stoning process. However, despite the improvement of the nutritional value, in the past the de stoned oil didn't achieve marketing success mainly in relation to technological limitations (i.e. low oil yield). Only in recent years healthy properties became an element able to influence consumers' behavior, overcoming the limit of low oil yields and attracting the attention of olive oil producers. An analysis of the advantages, in terms of product quality and process sustainability, is given in this review. Here, for the first time, the fragmented results reported in literature are critically analyzed underlining the contradictions reported by different authors showing the main reasons for the unlucky fate of this technology in the industrial sector. In the final section the challenges, that future research must focus on, are presented, including emerging technologies in VOO processing. Literature data, for the first time discussed here exhaustively, show that de-stoning technology is a mechanical strategy useful to increase the nutritional and the sensory quality of the product. Moreover, it reduces the depletion of natural resources obtaining a selective crushing of the drupe by removing the stones from the olive paste so increasing the sustainability and efficiency of VOO extraction plants. PMID- 29579970 TI - Mimicking gluten functionality with beta-conglycinin concentrate: Evaluation in gluten free yeast-leavened breads. AB - Fractionation of soy proteins has proved to produce protein concentrates with viscoelastic properties. In the present study, a beta-conglycinin concentrate (betaCC) obtained by a pH fractionation of soy flour was tested as structuring agent in gluten-free yeast-leavened bread model. A lean formulation with betaCC and corn starch was used to produce gluten-free breads with two hydration conditions and three levels of protein (5%, 10% and 15%). Vital gluten was used to compare the functionality of betaCC protein and its performance for breadmaking. Breads were characterized in moisture, color, textural parameters and image analysis. betaCC presented lower hydration properties and higher emulsifying activity compared to vital gluten. Blends betaCC:starch had higher water binding capacity compared to vital gluten blends. The hydration conditions tested affected the moisture, color and cell density of breads. Breads produced with betaCC presented higher 2D area and height and presented higher crumb softness and cohesiveness, and did not present significant differences in springiness and resilience compared to vital gluten breads. The image analysis of crumbs showed higher cell density but lower porosity and mean cell areas in betaCC breads. Thus, betaCC proved to have potential as a structuring agent in gluten-free breads. PMID- 29579971 TI - Alterations in the morphological, sugar composition, and volatile flavor properties of petai (Parkia speciosa Hassk.) seed during ripening. AB - Petai seeds are one of the well-known strong-smelling foods of the Southeast Asian region that have been harvested and commercially offered in different ripening forms. The current study focused on alterations in the size, color, sugar composition, and volatile flavor properties of petai seeds in the four ripening stages (unripe, mid ripe, ripe, and over-ripe). The ripening process was mainly indicated by the increase in size and weight as seed color turned paler and less greenish. The total sugar content gradually increased during ripening, and then elevated from 1.60 g/100 g (ripe seed) to the level of 2.82 g/100 g in the over-ripe seed. Ripening also altered the volatile flavor composition of petai seed, wherein the predominant aldehydes (hexanal and acetaldehyde) were decreased, and the sulfuric compounds (hydrogen sulfide, methanethiol, and 1,2,4 trithiolane) tended to increase. Additionally, gas chromatography-olfactometry (GC-O) analysis revealed alterations in the perceived odor strength and sensation of each volatile compound and demonstrated volatile flavor profiles, viz. detection percentages of volatile group odor strengths and descriptive odors, of petai seed. These results provide valuable information for monitoring alterations in the physical appearance, sugar composition, and aroma that represent the flavor quality in seasonal petai seed. PMID- 29579972 TI - Volatile molecular markers of VOO Thermo-oxidation: Effect of heating processes, macronutrients composition, and olive ripeness on the new emitted aldehydic compounds. AB - Heating operation has been applied to Chetoui extra-virgin olive oils (EVOOs) extracted from fruits with several ripening stages (RS). The studied samples, were subjected to microwave and conventional heating. Results showed that heated VOOs after 2.5 h and 7 min of conventional and microwave heating, respectively, gave rise to a drastically decrease of LOX products and allowed the detection of toxic new formed aldehydic volatiles (alkanal: nonanal, alkenals: (Z)-2-heptenal and (E)-2-decenal, and alkadienals: (E.E)-2.4-decadienal), which can be used as markers of VOO degradation. Their abundance in the VOO headspaces depends on their boiling points, the rate of their possible degradation to yield other compounds, on the heating processes and on the rate of macronutrients. The emission rate of the new synthesized volatiles during heating processes was mainly attributed to enzymatic oxidation of some fatty acids. Hexanal, (Z)-2 heptenal, (E)-2-octenal, (E)-2-nonenal, (E,E) and (E,Z)-2,4-decadienal, and (E,E) 2,4-nonadienal, derived from linoleic acid, and heptanol, octanal, nonanal, decanal, (E) and (Z)-2-decenal, (E)-2-undecenal, and (E,E)-2,4-nonadienal, are emitted after degradation of oleic acid. During thermo-oxidation, the ECN44 (LLO, and OLnO), and the ECN46 (OLO, and PLO + SLL) compounds decreased, whereas, the ECN48 (OOO, and PPO), and the ECN50 (SOO) compounds increased when temperature and heating time increased. The several variations of the studied biochemical compounds depend to the heating processes. Ripening stage of olive fruits can be used as a tool to monitor the emission rate of the aldehydic volatiles, but cannot be used for a chemometric discrimination. PMID- 29579973 TI - On printability, quality and nutritional properties of 3D printed cereal based snacks enriched with edible insects. AB - 3D printing technology was employed to obtain snacks with a designed cylindrical geometry from wheat flour dough enriched by ground larvae of Yellow mealworms (Tenebrio molitor) as novel source of proteins. The main microstructural features, overall quality, and nutritional attributes were studied as a function of formulation, time and temperature of baking. The addition of ground insects up to 20 g/100 g (d.b.) resulted in softer dough. This caused an overflow in dough deposition producing the increase in diameter, height and weight of snacks. Baking conditions did not alter the overall aspect of the snacks, but modification of the main dimensional and microstructure attributes were observed due to the better water evaporation. The optimization of baking conditions found that 22 min and 200 degrees C allowed obtaining a maximum desirability of 0.693. Baked in these conditions, the printed snacks enriched with 10 and 20% of ground insects significantly increased the total essential amino acid, from 32.5 (0% insects) to 38.2 and 41.3 g/100 g protein, respectively. The protein digestibility corrected amino acid score increased from 41.6 to 65.2 from 0 to 20% insect enrichment, with lysine and methionine + cysteine being the respective limiting amino acid. Our results evidenced the rational promotion of insects based on nutritional arguments and validated the use of 3D printing as technology to manufacture innovative printed snacks without adverse impact on technological quality. PMID- 29579974 TI - Determination of four Alternaria alternata mycotoxins by QuEChERS approach coupled with liquid chromatography-tandem mass spectrometry in tomato-based and fruit-based products. AB - A liquid chromatography-tandem mass spectrometry method for the determination of four Alternaria toxins, i.e. alternariol, alternariol monomethyl ether, tentoxin, and tenuazonic acid in tomato-based and fruit-based products was developed using a QuEChERs approach for the extraction of the mycotoxins. To optimise the QuEChERs extraction, several parameters were tested: types of QuEChERs pouches, sample weights, quantities of added water, use of dispersive SPE as a purification step, types of solvent and conditions of shaking. The method showed good linearity (R2 > 0.997) and precision (RSD% < 10) for all analytes. Tenuazonic acid showed very good recovery (98.8%-108.9%) for tomato-based products, as well as for fruit-based products. The method was successfully applied to 57 samples collected from the Italian market. Tenuazonic acid was found in appreciable concentrations in some products. The highest value was found in a tomato sauce sample (814 MUg/kg). PMID- 29579975 TI - Analysis of volatile compounds in gluten-free bread crusts with an optimised and validated SPME-GC/QTOF methodology. AB - The aroma of bread crust, as one of the first characteristics perceived, is essential for bread acceptance. However, gluten-free bread crusts exhibit weak aroma. A SPME-GC/QTOF methodology was optimised with PCA and RSM and validated for the quantification of 44 volatile compounds in bread crust, extracting 0.75 g of crust at 60 degrees C for 51 min. LODs ranged between 3.60 and 1760 MUg Kg-1, all the R2 were higher than 0.99 and %RSD for precision and %Er for accuracy were lower than 9% and 12%, respectively. A commercial wheat bread crust was quantified, and furfural was the most abundant compound. Bread crusts of wheat starch and of japonica rice, basmati rice and teff flours were also quantified. Teff flour and wheat starch crusts were very suitable for improving gluten-free bread crust aroma, due to their similar content in 2-acetyl-1-pyrroline and 4 hydroxy-2,5-dimethyl-3(2H)-furanone compared to wheat flour crust and also for their high content in pyrazines. PMID- 29579976 TI - In vitro lipolysis of dairy and soy based infant formula. AB - Hydrolysed and non-hydrolysed dairy and soy proteins with vegetable oils are commonly used in infant formulations. Lipid digestion of these infant formula emulsions was studied under an in vitro gastrointestinal condition for 60 min in the stomach and 120 min in the small intestine (with and without the presence of enzyme proteases). The distribution of oil droplets, the released free fatty acids, and micro-structure changes of the digesta were monitored over the digestion period. Oil droplet coalescence was observed during gastric phase but not in the intestinal phase for most of formulations. The emulsion structure and the oil-water interface of the oil droplets play an important part in lipolysis kinetics. Higher rate of lipolysis in infant formula emulsion stabilized by hydrolysed proteins was noted. The obtained results suggest that digestive proteases had a limited impact on lipolysis of infant formulations. PMID- 29579977 TI - Influence of time orientation on food choice: Case study with cookie labels. AB - Time orientation can influence health-related behaviors, including food consumption. The aim of the present work was to study the influence of time orientation on food choice, using cookie labels as case study. A choice-conjoint task was designed using labels differing in type of cookie (chocolate chips vs. granola), front-of-pack nutrition information (nutritional warnings vs. Facts Up Front system) and nutritional claim (no claim vs. "0% cholesterol. 0% trans fat"). An online study was conducted, in which 155 participants evaluated 8 pairs of cookie labels and selected the one they would buy if they were in the supermarket. Then, they were asked to complete a consideration of future consequences scale (CFC) adapted to eating habits, as well as a questionnaire about socio-demographic characteristics. Time orientation influenced participants' choices of cookies labels; particularly the importance attached to type of cookie. Participants with greater consideration of future consequences preferred the granola cookies, associated with health, while those who prioritized immediate consequences preferred chocolate chip cookies. In addition, nutritional warnings discouraged choice regardless of participants' time orientation. Results from the present work provide additional evidence of the influence of time preferences on food choices and suggest that strategies to stimulate and generate a more future-oriented perspective on eating habits could contribute to more healthful food choices. PMID- 29579978 TI - Cytotoxic, proapoptotic and antioxidative potential of flavonoids isolated from propolis against colon (HCT-116) and breast (MDA-MB-231) cancer cell lines. AB - Isolated and structurally confirmed, eleven flavonoids from propolis were examined for their cytotoxicity toward human colon cancer and human breast cancer cells. Their effect on induction of apoptosis and their antioxidative activities were also evaluated. Six flavonoids induced cytotoxic effects in both cell lines. Luteolin had a marked effect on both cell lines, especially on HCT-116 cells (IC50 72h, 66.86MUM). Also, luteolin was observed to have the highest apoptotic potential after 72h treatment of examined cell lines (27.13% and 37.09%, respectively). Myricetin exhibited selective inhibition of cell growth (IC50 114.75MUM) and induced apoptosis in MDA-MB-231 cells only. Luteolin and galangin exhibited prooxidative properties 24h after the treatment in HCT-116 cells, while myricetin induced prooxidative effects in MDA-MB-231 cells. On the other hand, selected flavonoids exhibited antioxidative properties 72h after the treatment, decreasing superoxide anion radical and nitrite levels in both cell lines. Cytotoxic and proapoptotic effects on colon and breast cancer cell lines and the influence on their redox status make tested flavonoids good candidates for developing new anticancer drugs. PMID- 29579979 TI - Cheese matrix protects the immunomodulatory surface protein SlpB of Propionibacterium freudenreichii during in vitro digestion. AB - Propionibacterium freudenreichii is a traditional Swiss-type cheeses starter and constitutes an emergent probiotic, exerting several beneficial effects, including anti-inflammatory modulation of gut inflammation. This feature relies on several metabolites and on surface proteins, with a prominent role of the surface protein SlpB. In this study, we firstly investigated the relevance to avoid SlpB digestive proteolysis, by comparing the effect of i) P. freudenreichii CIRM-BIA 129, ii) its native Slps, or iii) peptides resulting from Slps digestive proteolysis, with respect to modulation of HT-29 cells response to a lipopolysaccharide (LPS) challenge. The anti-inflammatory effect exerted by P. freudenreichii CIRM-BIA 129 and by its native surface proteins (Slps) on HT-29 cells was abolished by digestive proteolysis. This result confirmed the importance to protect immunomodulatory surface proteins from digestive proteolysis in order to allow gut immune system modulation. Thus, we examined the effect of dairy matrices on P. freudenreichii viability and on SlpB integrity during digestion. In comparison with liquid matrices, the cheese matrix provided an enhanced tolerance towards digestive stresses and protection of SlpB towards proteolysis, during two in vitro digestion models: static and dynamic. Taken together, these results show that cheese is an adequate delivery vehicle for P. freudenreichii immunomodulatory proteins. This opens perspectives for the development of fermented dairy functional foods aimed at target populations at high risk for diet-related diseases with an inflammatory component. PMID- 29579980 TI - Tayloring W/O/W emulsion composition for effective encapsulation: The role of PGPR in water transfer-induced swelling. AB - The role of the lipophilic surfactant, polyglycerol polyricinoleate (PGPR) in water transfer in food-grade double emulsions was investigated, and related to physical emulsion stability. Double (W/O/W) emulsions were prepared with various PGPR concentrations (0.5-5.0 wt%) in the oil phase, at initial osmotic pressure differences of up to 1.1 MPa between the water phases. At high PGPR concentrations (>2 wt%), emulsions showed good physical stability, with encapsulation efficiency close to 100%. It was found that PGPR is involved in water transfer between the water phases through reverse micelle formation by PGPR molecules or hydrated monomers of PGPR, and this allows for controlled swelling. Emulsions that are initially of low viscosity (milk-like emulsions), obtain an apparent viscosity of up to 3 Pa.s, and this effect can be used to tune the emulsion properties to the targeted application, whithout the need to gel either the internal or external phase.

AB - This paper reports on a study of chemical characterization and colour parameters of cv. Carignan red wines from six locations and two production years of the Chilean Maule valley. The chemical study was performed on polyphenolic composition (benzoic acids, hydroxycinnamic acid derivatives, stilbenes, flavan-3 ols, flavonols and anthocyanins) and several fractions of proanthocyanidins and polysaccharides. Results revealed that although significantly (p < 0.05) different content of anthocyanins were observed according to the production year, it could be possible to establish fingerprints of the different locations of the Maule valley wines. Thus, wines from zones closer to the Andes Mountains had higher content of procyanidin B3 (Caliboro), polysaccharides and cis-resveratrol glucoside (Loncomilla and Melozal), whereas the proximity to the Pacific Ocean provoked a unifying effect in chemical and colorimetric terms (Cauquenes, Sauzal and Huerta del Maule). PMID- 29579982 TI - Nutritional potential, chemical profile and antioxidant activity of Chicha (Sterculia striata) nuts and its by-products. AB - The Sterculia striata nut commonly known as chicha is consumed raw or toasted inBrazil but information on its chemical composition and antioxidant activity are scarce in the literature. In this work, the nutritional composition, minerals profile, lipid composition and phenolic compounds profile of chicha nuts and its by-products (pellicle and shell) were determined. The results showed that the nuts and the cake contain considerable amount of fibers and proteins and are rich in minerals (Fe, Mn and Cu). Oleic acid was the main fatty acid (37.8%), and PPO (36.0%) and POP (15.6%) were the main triacylglycerides present in the chicha oil. The phytosterols beta-sitosterol, stigmasteroland campesterol (1848.5MUgg-1, 542.2MUgg-1 and 186.3MUgg-1, respectively), and the gamma-, delta-, alpha- and beta-tocopherol (8.85; 2.10; 1.64, and 0.11mg100g-1, respectively) were identified in the oil. The antioxidant activity (ABTS and FRAP assays) followed the order pellicle>shell>nuts (13.25 and 84.65; 8.71 and 64.3; 5.85 and 36.79MUmolTEACg-1, respectively). The main phenolic compounds identified in the extracts were ellagic and ferulic acids; ellagic and protocatechuic acids; and protocatechuic, ellagic and methoxyphenylacetic acids for the nuts, shells and pellicle, respectively. A strong positive correlation was observed between total phenolic content and antioxidant activity determined by ABTS and FRAP assays (r=0.9067, p<0.01; and r=0.9584, p<0.01; respectively). Collectively, the results showed that the chicha is a nut of high nutritional value, rich in bioactive compounds.

AB - The highly acidic nature of the gastric fluids inside the human stomach can cause have health problems in certain individuals e.g., acid reflux and ulcers. Antacid loaded biopolymer microgels can be used to control the acidity of the gastric fluids, which may be useful for developing functional foods to treat these problems. In this study, the impact of biopolymer microgel dimensions and composition on the dissolution rate of encapsulated antacid was determined under simulated gastric conditions. The microgels were formed by injecting antacid (magnesium hydroxide) and biopolymers (alginate or alginate/pectin) into a calcium chloride solution to promote cross-linking. Microgels of varying dimensions were formed using either a hand-held syringe or a vibrating nozzle encapsulation device with different nozzle sizes. The rate of antacid dissolution was measured using an automatic titration device (pH stat) that added HCl solution into the simulated gastric fluids to maintain a constant pH of 2.5. The antacid dissolution rate decreased with increasing microgel diameter (300 to 1660 MUm) and decreasing pore size (0.8 to 2.0% alginate). The slowest dissolution rate was observed in microgels containing 80% alginate and 20% pectin, which may have been due to the impact of biopolymer composition on bead dimensions and pore size. The results of this study may be useful for the design of biopolymer microgels that can control the release of antacids in the stomach, thereby leading to better control over the pH of the gastric fluids.

AB - The texture of apples is paramount for determining fruit quality. This research explored the correlations among firmness determinations from the Sinclair iQTM Firmness Tester (SiQTM), the Aweta Acoustic Firmness Sensor (AFS), and eight measurements from the Mohr Digi-Test-2 (MDT) instrument. Assessments were conducted on a collection of nine apple cultivars (Ambrosia, Aurora Golden GalaTM, Honeycrisp, Fuji, Imperial Gala, McIntosh, Pink LadyTM, Silken, SalishTM), with a broad range of firmness values, in each of two years. Sensory analysis of the apples was conducted using a semi-trained panel (n = 10) to evaluate crispness, hardness, juiciness and skin toughness, in quadruplicate at two testing dates, providing eight data points per cultivar per year. Inter correlations of the instrumental firmness determinations (SiQTM, AFS, MDT) revealed that most values were highly correlated with one another (r > 0.500 n = 72). This suggested that the instruments were tracking similar, but not identical, underlying characteristics. Multiple regression models were developed using the 2016 data to predict the sensory attributes from the instrumental and compositional (titratable acidity, soluble solids concentration, absorbed juice) analyses. Models with the highest R2 were cross-validated using the 2015 data. Accuracy of these models was evaluated using R2 and prediction standard errors (PSEs) - an index quantifying the difference between the predicted and actual values. In general, simple 1- and 2-variable models satisfactorily predicted hardness and crispness, with the R2 values ranging between 85 and 89%, while more complex non-linear models were required to predict juiciness and skin toughness. Correlations coefficients reported in this research allow for interconversion of experimental firmness data, as determined by the SiQTM, AFS and MDT. Regression models predicting hardness, crispness and juiciness from instrumental/compositional analyses, revealed that the quality factor (QF) variable was particularly important for estimation of textural characteristics. Therefore the MDT, among the instruments evaluated, was the instrument of choice for quality assessment of apples. Since cross-validation of the models accounted for a high proportion of the variance (70-82%) in a new data set with small PSEs (2.67-6.36) (on a 100-unit scale), the developed models were appropriate for estimating the apple textural attributes. PMID- 29579985 TI - Application of a recombinant laccase-chlorogenic acid system in protein crosslink and antioxidant properties of the curd. AB - Milk protein crosslink through the action of enzymes represents a feasible strategy to impart new functionalities to cheese. In this work we reported the effects of a laccase mediator system (LMS) on protein crosslink and antioxidant property of curd. The crosslinking activity of a purified recombinant laccase Ery4 and a commercial enzyme preparation (cLC), with three mediators was firstly evaluated in milk and then applied before curd manufacture. Only Ery4-LMS significantly increased curd weight compared to that of the control sample. SDS PAGE revealed that similar high molecular weight bands produced by both LMSs in milk were also retained in curds. The antioxidant activity recorded in curds with Ery4-LMS was the highest among all samples both before and after gastro pancreatic digestion. This is the first time that a CGA-based LMS is used in manufacture of curd with improved antioxidant properties. These results open new perspectives for dairy applications. PMID- 29579986 TI - Ohmic Heating: A potential technology for sweet whey processing. AB - The use of Ohmic Heating (OH) for sweet whey processing was investigated in this study. Whey samples were subjected to both different OH parameters (2, 4, 5, 7 and 9 V.cm-1 at 60 Hz, up to 72-75 degrees C/15 s) and conventional processing (72-75 degrees C/15 s). Physicochemical analyses (pH), color measurements (L*, a*, b*), rheological properties (flow curves and particle size distribution), microstructure (optical microscopy), bioactive compounds (ACE and antioxidant capacity), microbiological characterization (mesophilic bacteria, total coliforms, and thermotolerant coliforms), water mobility (TD-magnetic resonance domain), and sensory evaluation (descriptive analysis) were carried out. The OH effects on sweet whey characteristics depended on the applied electric field intensity. Higher saturation, higher color variation (DeltaE*), and higher luminosity (L*) were observed in low electric fields. For bioactive compounds, the increase of the electric field negatively affected the preservation of the antioxidant capacity and the ACE Inhibitory Activity of bioactive peptides. OH and conventional samples exhibited a pseudo-plastic behavior (n < 1). OH performed at 4 and 5 V.cm-1 was able to provide similar levels of sensory profile and higher volatile compounds levels. The results suggested the OH technology as an interesting alternative to whey processing. PMID- 29579987 TI - Inactivation kinetics of Escherichia coli in cranberry juice during multistage treatment by electric fields. AB - The inactivation of Escherichia coli inoculated in cranberry juice by processing with radio frequency electric fields was studied. E. coli ATCC 35218 was chosen among three non-pathogenic strains based on its ability to survive in low pH cranberry juice. Studies were conducted by measuring the survival population when changing the electric field strength between 2.2 and 13.2 kV cm-1, number of treatment stages from 1 to 6 and flow rates between 13 and 25 L h-1 at moderate temperatures of 20, 30 and 40 degrees C. A minimum inactivation of 5-log reduction, as requested by the Food and Drug Administration (FDA), can be achieved by increasing the number of treatment stages, temperature or both. At 40 degrees C and 6 treatment stages, 6.57 +/- 0.02 log CFU ml-1 reduction in the initial population of E. coli (ATCC 35218) was obtained. At a constant electric field, increasing the temperature produced higher microbial inactivation, consuming lower radio frequency energy input, than increasing the number of treatment stages. Furthermore, a primary model that accounts for the combined effect of time and electric field is proposed. The model represented the sigmoidal curve composed of shoulder, log-linear and tailing sections as observed when changing electric fields. A secondary model that accounts for the effect of temperature and flow rate on the primary model constants is also proposed. The combined primary and secondary models were found to fit the data well with a high coefficient of determination (R2 = 0.965). The proposed model can be extended to kinetic models for pulsed electric fields. PMID- 29579988 TI - Assessment of the color modulation and stability of naturally copigmented anthocyanin-grape colorants with different levels of purification. AB - Grape skins or their by-products from wine production are rich sources of anthocyanins and various colorless phenolics, depending on the grape variety. Phenolics have strong antioxidant and anthocyanin stabilizing properties and help to produce functional anthocyanin colorants with improved stability. This study aimed to assess differences in color expression and stability of anthocyanin colorants from red grape varieties naturally copigmented and with different levels of purity and to compare them to synthetic FD&C Red No. 3. Model juice systems were prepared at pH 3.5 with anthocyanins and phenolic copigments extracted from four Vitis vinifera grape varieties ('Tempranillo', 'Syrah', 'C. Sauvignon', and 'Graciano') both crude and purified by C18 solid phase extraction. Attention was focused on differential colorimetry and phenolic composition related to the color. Degradation kinetics of total color were also studied during storage of 17 days in darkness at 25 degrees C. Grape variety significantly influenced pigment yield, proportion of acylation, and proportion of copigments:pigments ratios in crude extracts; purification modulated the copigment:pigment ratios. This proportion was related to perceptible color variability among colorants and to different stabilities. With the same pigment content, grape varieties richer in skin copigments and higher copigment/pigment ratios ('Syrah' and 'Tempranillo') produced more intensely colored crude extracts whose tonalities ranged from reddish ('Graciano') to red-bluish ('Syrah'), depending on the proportion of acylation. Increasing the purity of the pigments diminished the color variability due to variety, making them less vivid and visually more similar to one another and also to the synthetic colorant. Degradation kinetic studies showed that unpurified grape colorants had higher color stability over time, with the greatest stabilizing effects achieved with varieties richer in skin flavonols ('Tempranillo' and 'Syrah'). PMID- 29579989 TI - Fabrication of beta-conglycinin-stabilized nanoemulsions via ultrasound process and influence of SDS and PEG 10000 co-emulsifiers on the physicochemical properties of nanoemulsions. AB - Nanoemulsions stabilized by beta-conglycinin (7S), beta-conglycinin/sodium dodecyl sulfate (SDS) and beta-conglycinin/polyethylene glycol 10000 (PEG 10000) were produced via ultrasound process. All the nanoemulsions showed the desired mean particle size and narrow size distribution. The effects of pH, ionic strength and temperature on the properties of the nanoemulsions were investigated, and the long-term stability of the fabricated nanoemulsions was also monitored during storage at 4 degrees C. The nanoemulsions prepared by 7S exhibited a good stability over various pH (<4 or >5), ionic strength (0-500 mM NaCl), thermal treatment (80 degrees C) and storage time (0-45 days). The stability of 7S nanoemulsions was enhanced by adding SDS, whereas reduced by adding PEG 10000, which could be attributed to the higher zeta-potential in the present of SDS leading to stronger electrostatic repulsion against droplet flocculation, whereas opposite was observed for the addition of PEG 10000. Therefore, this study provided important evidences for the fabrication of nanoemulsions using protein/surfactant complexes as the emulsion stabilizer via ultrasound process. PMID- 29579990 TI - Stability and release behavior of encapsulated flavor from spray-dried Saccharomyces cerevisiae and maltodextrin powder. AB - Yeast cells (Saccharomyces cerevisiae), from which beta-glucans have been partially extracted, were used to encapsulate flavor inside the lipid bilayer membrane as natural encapsulant. The focus of this study was to investigate the release and stability of flavors (d-limonene and ethyl hexanoate) encapsulated in yeast cells and maltodextrin (MD) (DE = 19) by spray drying. The release behavior of encapsulated flavors from yeast cells was measured at 40, 60, 80, and 105 degrees C with different moisture content (0, 50, 100, and 200% of powder). Water affected flavor release from the yeast cells. The release rate constants were correlated using Gaussian distribution of the activation energy of the release rate constants. The release of d-limonene from the spray-dried MD powder showed a different trend than that of yeast cells at various temperatures. The activation energies of the release rate constant for ethyl hexanoate and d-limonene from yeast were 55 and 49 kJ/mol, respectively, under a wet condition. The formation rates of limonene oxide and carvone were slower in yeast than that of MD powder at 30 degrees C after 2 months. PMID- 29579991 TI - Valorization of okara oil for the encapsulation of Lactobacillus plantarum. AB - Oil-in-water (O/W) emulsions of okara oil-caseinate (1:2; 1:3 and 1:4 O/W ratios) were used to encapsulate Lactobacillus plantarum CIDCA 83114. Once encapsulated, microorganisms were freeze-dried or spray-dried, and observed by scanning electronic and confocal microscopies. A physical characterization of the dehydrated capsules was carried out by determining their moisture content, water activity, particle size, polydispersity index and zeta potential. Determining the induction times and peroxide values provided information about their susceptibility to oxidation. In turn, bacterial stability was analyzed by plate counting before and after freeze-drying and spray-drying, and during storage at 4 degrees C. Spray-dried emulsions had lower Z-sizes and polydispersity indexes, higher induction times and lower peroxide values than the freeze-dried ones, thus resulting better systems to protect L. plantarum CIDCA 83114. In addition, the culturability of spray-dried bacteria did not decrease neither after spray-drying nor up to 60days of storage at 4 degrees C. The results showed that the better physical-chemical stability of spray-dried capsules determined the greater stability of microorganisms. This demonstrates the importance of defining adequate emulsions' formulations for an efficient encapsulation of microorganisms, with promising applications in the development of novel functional foods. PMID- 29579992 TI - Mild high hydrostatic pressure pretreatments applied before soaking process to modulate wholegrain brown rice germination: An examination on embryo growth and physicochemical properties. AB - This investigation aimed to examine the effects of a novel processing pattern, combining high hydrostatic pressure (HHP) with germination, on the embryo growth and physicochemical characteristics of wholegrain brown rice (WBR). WBR grains were firstly subjected to mild HHP stress (30-90 MPa/5 min) and then incubated at 37 degrees C for 52 h for obtaining germinated samples (GBR). The results showed that HHP shock resulted in a delayed embryo growth of WBR grains, maintaining acceptable sprouting rates ranging from 65% to 76% when germination was finished. The contents of gama-aminobutyric acid in GBR were greatly increased responding to HHP stress, showing pressure intensities dependent. Total digestible and resistant starch contents in samples stressed at 60/90 MPa were decreased, mainly associated with high pressure-induced amorphization as revealed by SEM imaging and FTIR, which promoted starch hydrolysis during germination. Besides, the levels of zinc and iron were influenced by HHP pretreatments due to the high pressure-mediated degradation behavior for phytic acids. The storability of HHP stressed GBR grains was significantly enhanced through reducing free fatty acids formation and maintaining color stability during a storage testing. These results obtained from the current work demonstrated that mild HHP stress pretreatment prior to germination process could be used as a promising strategy to modulate certain physicochemical characteristics of WBR products. PMID- 29579993 TI - Metabolic variation and cooking qualities of millet cultivars grown both organically and conventionally. AB - Millet plays a major role in food security in Africa and Asia. In addition to being a rich source of nutrients, millet contains many phytochemicals that are potentially beneficial for human health, and several of these compounds are related to its cooking properties. In this study, 172 metabolites and 3 cooking quality traits of millet from the same two cultivars grown both organically and conventionally were analyzed. The results indicated that the differences in the metabolities and cooking quality of the millets could be attributed mostly to the cultivar and whether the millet was grown conventionally or organically. Organic growing conditions only enhanced the accumulation of some carbohydrates such as fructose and glucose. Therefore, cultivar selection was important in organic millet cultivation. The relationships between metabolites and cooking quality traits showed that, overall, 57.43% of the variation in the cooking quality matrix was explained by metabolome matrix, which indicated that some chemical compounds could also be used to evaluate the cooking qualities of millet. These results could contribute to breeding millet to improve its the nutritional properties and cooking qualities. PMID- 29579994 TI - Standardizing the analysis of phenolic profile in propolis. AB - The analysis of propolis is controversial, hampering the comparison of its biological properties and estimation of its commercial value. This work evaluates the effectiveness of combining maceration and ultrasonication extraction techniques on the yield, total phenol content (Folin-Ciocalteau) and the specific phenolic compounds (HPLC-UV), on propolis from different origins. The extraction method was not significant in any case; therefore ultrasonication is recommended (time-saving) but only when a double extraction is performed. Propolis yield varies significantly between samples, as it includes impurities, consequently the results should be expressed considering the yield (as balsam) instead of raw propolis. Of the 13 quantified phenolic compounds, CAPE and pinocembrin (803 and 701 mg/g balsam) stand out. The phenolic profile of a propolis must be fixed using both total phenol content (with a consensus reference compound) and the specific phenolic compounds, since the latter provides information about compounds that can play a significant antioxidant role. PMID- 29579995 TI - Metabolomics approach for understanding geographical dependence of soybean leaf metabolome. AB - The soybean plant (Glycine max) is widely used as an ingredient in various foods, nutraceuticals and cosmetics, due to their diverse bioactive compounds. Their metabolic compositions are likely affected by environmental conditions during growth. To investigate the influence of different environmental conditions on the metabolite composition of soybean leaves, we cultivated soybean (G. max Sinhwa) in the southernmost island and volcanic region of Korea, and in the central section and limestone region of the Korean peninsula. Comprehensive metabolite variations of their leaves were analyzed through 1H NMR-based metabolomics approach. With marked differences in soil compositions and climatic conditions between the two growing areas, differences in accumulations of pinitol and diverse flavonoids were noted between the soybean leaves, reflecting the distinct metabolism of soybean plants for physiological adaptation toward different environmental conditions. Therefore, the current study highlights the geographical dependences of diverse soybean leaf metabolites for developing biofunction-enhanced soybean products. PMID- 29579996 TI - Effects of sonication on the physicochemical and functional properties of walnut protein isolate. AB - The objective of this study was to investigate the impact of high-intensity ultrasound treatment (sonication) on the molecular, physicochemical, and functional properties of walnut protein isolate. Aqueous walnut protein suspensions were sonicated at varying power levels (200, 400 or 600 W) and times (15 or 30 min), and then any alternations in protein structure and properties were determined. SDS-PAGE demonstrated that there were no changes in protein electrophoretic patterns, indicating that sonication did not break covalent bonds. Circular dichroism spectroscopy indicated a small change in protein secondary structure after sonication, with a decrease in alpha-helix and increase in beta-sheet, beta-turn, and random coil content. There was an increase in surface free sulfhydryl (SH) groups and a decrease in fluorescence intensity after sonication, indicating that appreciable changes in tertiary structure occurred. Ultrasound reduced the size of the particles in aqueous walnut protein dispersions as confirmed by static light scattering and scanning electron microscopy, suggesting that sonication dissociated protein aggregates. Moreover, the water-solubility (+22%), emulsifying activity index (+26%), and emulsifying stability index (+41%) all increased after sonication. These results suggest that sonication is a valuable tool for improving the functional attributes of walnut proteins. PMID- 29579997 TI - Cold atmospheric pressure ambient air plasma inhibition of pathogenic bacteria on the surface of black pepper. AB - In present study, the inhibition effect of low temperature plasma on Bacillus subtilis, Escherichia coli, Salmonella Enteritidis and B. subtilis endospores inoculated on the surface of black peppercorns was studied. Plasma was generated by Diffuse Coplanar Surface Barrier Discharge (DCSBD) at atmospheric pressure in ambient air. Plasma treatment time of 300 s led to log10 CFU/g reduction of B. subtilis from 7.36 to 2.30 and B. subtilis endospores from 4.42 to 2.39. Plasma treatment reduced the number of E. coli and Salmonella Enteritidis to below detection level (1.0 log10 CFU/g) from initial populations of 7.45 log10 CFU/g and 7.60 log10 CFU/g, respectively. The inactivation kinetics was explained by Weibull model. Decimal reduction times (D-values) for B. subtilis, E. coli, Salmonella Enteritidis, and B. subtilis endospores were determined as 43 s, 47 s, 58 s, and 142 s, respectively. The surface morphology observed by Scanning Electron Microscopy showed no significant changes after the plasma treatment. The influence of plasma on chemical bonds on the surface and inside the peppercorns was studied by Attenuated Total Reflectance - Fourier Transform Infrared Spectroscopy. PMID- 29579998 TI - 1H NMR-based metabolomic profiling for identification of metabolites in Capsicum annuum cv. mirasol infected by beet mild curly top virus (BMCTV). AB - Beet mild curly top virus (BMCTV) is associated with an outbreak of curly top in chili pepper, tomato and other Solanaceae species, which can cause severe crop losses. The aim of this work was to obtain the 1H NMR metabolomic profiling of both healthy chili peppers (cv. mirasol) and infected chili peppers with BMCTV in order to find chemical markers associated to the infection process. Significant differences were found between the two groups, according to principal component analysis and orthogonal projections to latent structure discriminant analysis. Compared to the asymptomatic peppers, the symptomatic fruits had higher relative abundance of fructose, isoleucine, histidine, phenylalanine and tryptophan. Contrarily, the asymptomatic samples showed greater amounts of malonate and isobutyrate. These results suggest that in diseased chili peppers there are metabolic changes related to the viral acquisition of energy for replication and capsid assembly. This is the first study describing the chemical profiling of a polar extract obtained from Capsicum annuum infected by BMCTV under open field conditions. PMID- 29579999 TI - Influence of in vitro digestion process on polyphenolic profile of skin grape (cv. Italia) and on antioxidant activity in basal or stressed conditions of human intestinal cell line (HT-29). AB - White table grape cv. Italia is a typical component of the Mediterranean diet and a source of phenolic compounds, particularly abundant in the skin portion. The aim of this study was to characterize the phenolic profile of the table grape skin and to assess its stability after the in vitro digestion process. The main phenolic compounds identified by the HPLC-DAD analysis were: procyanidin B1, caftaric acid, catechin, coutaric acid, quercetin 3-glucuronide and quercetin 3 glucoside. All compounds showed a good stability after in vitro digestion (from 43 to 80%). Moreover, the influence of grape skin polyphenols on the modulation of ROS and GSH levels was evaluated in basal and in stressed conditions on human intestinal cells (HT-29). In basal conditions, a higher polyphenol concentrations exerted pro-oxidant effect corresponding to high ROS level and low GSH content. This effect was probably due to the polyphenolic oxidation in cell culture condition with consequent production of hydrogen peroxide. Otherwise, in stressed conditions, grape skin polyphenols exerted antioxidant effects up to 1.3 * 10-6 MUg/g and restored the stress-related GSH reduction. The in vitro digestion process attenuated the biological effect of grape skin polyphenols on intestinal cell line (HT-29). In conclusion, grape skin polyphenols showed different behavior in relation to their concentrations and to the intracellular ROS levels. PMID- 29580000 TI - The effect of dense phase carbon dioxide on the conformation of hemoglobin. AB - Dense phase carbon dioxide (DPCD) sterilization is a non-thermal sterilization technology used to process heat-sensitive foods. Although nutritional and sensorial quality of food is preserved while unwanted microbial activity is reduced during DPCD sterilization, the effect on protein structure remains unclear. In this work, the effect of DPCD on the higher order structure and fluorescence properties of Hemoglobin (Hb) was investigated. The different conditions assessed during DPCD processing included variation in pressure, pH and heating conditions. Results from this study showed an inversely proportional correlation between alpha-helical content of Hb and pressure. As the pressure was lowered, the levels of alpha-helical content increased. The increased levels of alpha-helix correlated with a lower fluorescence intensity and a limited redshift in the fluorescence emission wavelength. TEM imaging showed that DPCD processing resulted in Hb with larger molecular diameters, which became smaller as the pressure increased. Interestingly, after 7-day storage at 4 degrees C, an increase in alpha-helical content was observed. Results from this work show that DPCD sterilization does impact the conformation of hemoglobin, with a notable impact on secondary and tertiary structure. PMID- 29580001 TI - Comparison of rapid descriptive sensory methodologies: Free-Choice Profiling, Flash Profile and modified Flash Profile. AB - Rapid sensory methods have been developed as alternatives to traditional sensory descriptive analysis methods. Among them, Free-Choice Profiling (FCP) and Flash Profile (FP) are two that have been known for many years. The objectives of this work were to compare the rating-based FCP and ranking-based FP method; to evaluate the impact of adding adjustments to FP approach; to investigate the influence of the number of assessors on the outcome of modified FP. To achieve these aims, a conventional descriptive analysis (DA), FCP, FP and a modified version of FP were carried out. Red wines made by different grape maturity and ethanol concentration were used for sensory testing. This study showed that DA provided a more detailed and accurate information on products through a quantitative measure of the intensity of sensory attributes than FCP and FP. However, the panel hours for conducting DA were higher than that for rapid methods, and FP was even able to separate the samples to a higher degree than DA. When comparing FCP and FP, this study showed that the ranking-based FP provided a clearer separation of samples than rating-based FCP, but the latter was an easier task for most assessors. When restricting assessors on their use of attributes in FP, the sample space became clearer and the ranking task was simplified. The FP protocol with restricted attribute sets seems to be a promising approach for efficient screening of sensory properties in wine. When increasing the number of assessors from 10 to 20 for conducting the modified FP, the outcome tended to be slightly more stable, however, one should consider the degree of panel training when deciding the optimal number of assessors for conducting FP. PMID- 29580002 TI - Improved freeze drying efficiency by ice nucleation proteins with ice morphology modification. AB - This study aims to use ice nucleation proteins (INPs) as a novel approach to improve the efficiency of freeze drying process and investigate the related mechanism of ice morphology. Our results show that INPs can significantly improve freeze drying efficiency with increased primary drying rate under the increase of INP concentration from 0 to 10-2mg/mL. Moreover, such improvement was more significant at higher subzero freezing temperatures with the addition of INPs, when the control samples were unable to freeze. Those improvements further lead to reduced total drying time, which suggests an estimated total energy saving of 28.5% by INPs. Our ice morphology results indicate the ability of INPs to alter ice morphology with lamellar ice structure and larger crystal size, which both show linear relationships with primary drying rate. The results further suggest that these ice morphology characteristics induced by INPs are very likely to facilitate the water vapor flow and improve the sublimation rate. Additionally, the increase of freeze drying efficiency can also be achieved by INPs in other food systems like coffee and milk with elevated primary drying rate. The results of this study suggest great potential of using INPs to improve the efficiency of freeze drying process for a wide range of food products and other related applications. This study also provides new insights into the relationship between process efficiency and ice morphology. PMID- 29580003 TI - Kinetic modelling of ascorbic and dehydroascorbic acids concentrations in a model solution at different temperatures and oxygen contents. AB - The degradation kinetics of vitamin C (ascorbic and dehydroascorbic acids, AA and DHA) were determined under controlled conditions of temperature (50-90 degrees C) and oxygen concentrations in the gas phase (10-30% mol/mol) using a specific reactor. The degradation of vitamin C in malate buffer (20 mM, pH 3.8), mimetic of an apple puree, was assessed by sampling at regular intervals and spectrophotometric quantification of AA and DHA levels at 243 nm. The results showed that AA degradation increased with temperature and oxygen concentration, while DHA exhibited the behaviour of an intermediate species, appearing then disappearing. A kinetic model was successfully developed to simulate the experimental data by two first order consecutive reactions. The first one represented AA degradation as a function of temperature and concentration in dissolved oxygen, and the second reflected DHA degradation as a function of temperature only, both adequately following Arrhenius' law. PMID- 29580004 TI - Application of metabolomics profiling in the analysis of metabolites and taste quality in different subtypes of white tea. AB - Three subtypes of white tea, Silver Needle (SN), White Peony (WP), and Shou Mei (SM), differ in their taste, aroma, bioactivity, and commercial value. Here, a metabolomics investigation on the chemical compositions combining taste equivalent-quantification and dose-over-threshold (DoT) determination on the taste qualities were applied to comprehensively characterize the white tea subtypes for the first time. Significant differences in the contents of catechins, dimeric catechins, amino acids, phenolic acids, flavonol/flavone glycosides, and aroma precursors were observed among these 3 white teas. Metabolite content comparison and partial least-squares (PLS) analysis suggest that theanine, aspartic acid, asparagine, and AMP were positively correlated with the umami taste in white tea, and flavan-3-ols, theasinensins, procyanidin B3, and theobromine had positive correlations with higher bitterness and astringency tastes. In addition, puckering astringent (-)-epigallocatechin gallate (EGCG), ( )-epicatechin gallate (ECG) and theogallin, bitter-tasting caffeine, and the mouth-drying/velvety-like astringent gamma-aminobutyric acid (GABA) were identified as key taste compounds of white tea infusion by absolute quantification and DoT factor calculations. This work provided systematic and comprehensive knowledge on the chemical components, taste qualities, and sensory active metabolites for the subtypes of white tea.

PMID- 29580006 TI - The ultrasound assisted hydration as an opportunity to incorporate nutrients into grains. AB - Hydration is an important but long step in processing beans. Consequently, any ways of taking advantage of this processing time are desirable. One possibility is to fortify the beans during the hydration process, especially with water soluble nutrients. This work studied the incorporation of iron into beans during hydration with and without ultrasound, describing the kinetics of water and iron uptake, the entrance pathway and its effect on germination and the cooking process. For that, carioca beans were soaked in ferrous sulfate solution (0.271% w/v) with and without ultrasound (91 W/L; 25 kHz) at 25 degrees C. It was demonstrated that iron could be incorporated during the hydration process, describing a similar kinetics behavior to the water uptake. In addition, ultrasound accelerated this process, achieving 60.1 mg Fe/100 g w.b. after 510 min of process, in contrast to 34.4 mg Fe/100 g w.b. when the beans were hydrated without ultrasound. Finally, by hydrating the beans with ferrous sulfate, the cooking process was accelerated, which is desirable. However, the capacity for germination of the beans was reduced. In conclusion, the hydration process time can be used to fortify the beans with iron (and, possibly, other water-soluble nutrients). Nevertheless, future studies must be performed to determine if the incorporated iron is bioavailable and bioaccessible, as well as how relevant this approach is as a nutritional policy. PMID- 29580007 TI - Functional characterization of Lactobacillus plantarum ITEM 17215: A potential biocontrol agent of fungi with plant growth promoting traits, able to enhance the nutritional value of cereal products. AB - In this work, we explored the potential of 25 Lactobacillus plantarum strains isolated from cereals and milk-based products, testing characteristics related to antifungal activity and to nutritional quality. The tested strains demonstrated interesting beneficial traits, such as the ability to utilize fructo oligosaccharides, prebiotic substances that help probiotic microorganisms to grow in the human gut, and to reduce phytate, an antinutrient present in cereal sector. Regarding mould inhibition, we highlighted the ability of the strains to inhibit Penicillium roqueforti, Mucor circinelloides and mycotoxinogenic moulds associated with cereal grains as Aspergillus flavus, A. niger, Fusarium verticillioides. Moreover, a moderate reduction of the bioavailability of aflatoxin AFB1 was detected. The selected L. plantarum strain ITEM 17215, showed a strong inhibitory ability towards fungal growth and was able to produce 1,2 dihydroxybenzene, benzoic acid, p-hydroxyphenyllactic acid and 3-phenyllactic acid. The latter compound, already described as efficient antifungal inhibitor, was the most abundant and its concentration was further increased by adding phenylalanine and phenylpyruvic acid in the growth medium. The metabolites produced by strain ITEM 17215 could also be related to the ability of the strain to induce cereal germination and promote plant growth. This aspect, not yet investigated in L. plantarum, could have interesting applications in the agro food sector. PMID- 29580008 TI - Water-in-oil-in-water emulsion obtained by glass microfluidic device for protection and heat-triggered release of natural pigments. AB - Anthocyanins and norbixin are natural pigments used in food; however, they are unstable. The aim of this study was to evaluate the microencapsulation technique to protect these pigments. Elderberry extract (source of anthocyanins) and norbixin were encapsulated using a microfluidic device with palm oil as middle phase in a water-in-oil-in-water emulsion. The formulations were characterized for morphology, particle size, encapsulation efficiency, zeta potential, color release under heating, Fourier transform infrared spectrophotometry, and color stability under different conditions. Spherical, mononucleated microcapsules, with particle size of 187-190 MUm (elderberry) and 164-184 MUm (norbixin), and with encapsulation efficiencies values of 47.80-54.87% (elderberry) and 49.18 74.73% (norbixin) were obtained. The formulations showed high color retention, with the encapsulated elderberry extract stored at pH 3.0 being the most stable. This study shows that the microencapsulation of these pigments using a microfluidic device provided protection, and represents a new method for anthocyanins and norbixin delivery in foods.

AB - This study aims to examine the effects of non-hydrolyzed octopus (Octopus vulgaris) muscle proteins (NHOPs) and their hydrolysates (OPHs) on alloxan induced diabetes in Wistar rats (AIDR). Animals were allocated into seven groups of six rats each: control group (C), diabetic group (D) and diabetic rats treated with acarbose (D + Acar), non-hydrolyzed octopus proteins (D + NHOPs) and octopus proteins hydrolysates (D + OPHs) groups. The diabetic rats presented a significant increase in glycemic status such as alpha-amylase activity (in plasma, pancreas and intestine), hepatic glycogen, blood glucose and glycated hemoglobin (HbA1c) levels, as well as a significant decrease in the levels of plasma insulin and total hemoglobin compared to control group. In addition, plasma and liver contents in total cholesterol, triglycerides and LDL-cholesterol significantly increased in AIDR compared to control group. However, the daily administration of OPHs for 30 days improved the glucose tolerance test, the glycemic status of diabetic rats and corrected the lipid profiles. Further, a significant increase in the activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyl transpeptidase as well as in the level of plasma bilirubin on diabetic status was observed, indicating considerable hepatocellular injury. OPHs treatment was found to attenuate the increased activities of the plasma enzymes produced by diabetes and caused a subsequent recovery towards normalization compared to the control group. By contrast, the NHOPs treatment was found to increase the glucose metabolic disorders in AIDR. These beneficial effects of OPHs were confirmed by histological findings in the hepatic and pancreatic tissues of diabetic treated rats. Indeed, they avoid lipid accumulation in the hepatocytes and protect the pancreatic beta-cells from degeneration. Our results thus suggest that OPHs may be helpful in the preventing from diabetic complications by reversing hepatotoxicity. PMID- 29580010 TI - Physicochemical characterization of native and modified sodium caseinate- Vitamin A complexes. AB - Native and modified sodium caseinate- Vitamin A complexes {Sodium caseinate- Vit A complex by stirring (NaCas-VA ST), succinylated sodium caseinate- Vit A complex by stirring (SNaCas-VA ST), reassembled sodium caseinate- Vit A complex (RNaCas VA) and reassembled succinylated sodium caseinate- Vit A complex (RSNaCas-VA)} were prepared and characterized for their physicochemical characteristics e.g. particle size, zeta potential, turbidity analysis and tryptophan intensities which confirmed structural modification of both native (NaCas-VA ST) and modified (SNaCas-VA ST, RNaCas-VA and RSNaCas- VA) proteins upon complex formation with vitamin A. Binding of vitamin A to milk protein reduced the turbidity caused by vitamin A, however, the particle size and zeta potential of milk protein increased after complexation. Microstructure details of NaCas (spray dried) showed uniform spherical structure, however, other milk proteins and milk protein Vit A complexes (freeze dried) showed broken glass and flaky structures. Tiny particles were observed on the surface of reassembled protein and reassembled protein- Vit A complexes. Binding of vitamin A to milk protein did not have an influence on the electrophoretic mobility and elution profile (RP-HPLC). PMID- 29580011 TI - The effect of organic wheat flour by-products on sourdough performances assessed by a multi-criteria approach. AB - In this study, we determined the effect of organic (i) flour ash content (1% 1.4%) and (ii) flour by-product addition (bran, shorts and germ) on sourdough performances. After five consecutive back-sloppings, sourdough was used for bread making and its bread-related properties were assessed. No effect of flour composition factors (i & ii) on sourdough lactic acid bacteria and yeasts were highlighted. Nonetheless, they greatly altered lactic acid and acetic acid sourdough contents from 6.9 to 17.4 g/kg and from 0.9 to 2.2 g/kg, respectively. The flour ash content (i) had a significant and positive effect on sourdough acidity and CO2 production. Bread made with sourdough with a high ash content had a significantly higher acidity and specific volume. These physicochemical differences between breads were perceived by sensory evaluation in a significant way. Sourdough supplemented (ii) with germ had higher lactic acid and carbon dioxide contents than sourdough supplemented with bran and shorts. Hence, flour composition, combining ash content and flour by-products, appears to be an effective factor to obtain a better control of sourdough performances.

AB - Interesterification reaction involves rearrangement of the fatty acid radicals on the glycerol backbone, either randomly (chemical interesterification) or regioselectivity (enzymatic interesterification). Refined, bleached and deodourised palm oil (RBDPO) and palm kernel oil (RBDPKO) were blended in ratios from 25:75 to 75:25 (wt/wt). All blends were subjected to enzymatic (EI) and chemical interesterification (CI) using Lipozyme TL IM (4% w/w) and sodium methoxide (0.2% m/m) as the catalysts, respectively. The effect of EI and CI on the triacylglycerol (TAG) composition, thermal behaviour, polymorphism, crystal morphology and crystallisation kinetics were studied. The aim of this research is to characterise the nature of crystals in food product for certain desired structure. The crystallisation behaviour discussed in this study involves microstructure (PLM), polymorphism (XRD), thermal properties and crystallisation kinetics by DSC. The alteration in TAG composition was greater after CI as compared to EI with the reduction of LaLaLa (from 11.00% to 5.15%) and POO (from 14.28% to 4.87%). The DSC complete melting and crystallisation temperature of blend with 75% PO increased after CI, from 39.58 degrees C to 41.67 degrees C and from -30.84 degrees C to -28.33 degrees C, respectively. EI contributed to finer crystals than CI. However, the beta' and beta polymorph mixture and crystallisation kinetics (n = 2) of PO-PKO blends did not change after CI and EI. The knowledge on controlling crystallisation of RBDPO and RBDPKO blends is vital for proper processing condition like margarine production. PMID- 29580012 TI - Degradation of beta-casomorphins and identification of degradation products during yoghurt processing using liquid chromatography coupled with high resolution mass spectrometry. AB - Liquid chromatography-high resolution mass spectrometry (LC-HRMS) was used to investigate the degradation of beta-casomorphin 5 (beta-CM5) and beta-casomorphin 7 (beta-CM7) by Streptococcus thermophilus and/or Lactobacillus delbrueckii ssp. bulgaricus, and to identify the degradation products forming during yoghurt processing. Bovine UHT milk was fermented with: (i) a single strain of L. delbrueckii ssp. bulgaricus, (ii) a single strain of S. thermophilus and (iii) the mixture of S. thermophilus and L. delbrueckii ssp. bulgaricus to pH4.5 and then stored at 4 degrees C for 1 and 7days. Results showed that L. delbrueckii ssp. bulgaricus and/or S. thermophilus completely degraded beta-CM5 and beta-CM7 upon fermentation to pH4.5 and degradation products were significantly influenced by bacteria strains and storage time. Four peptides, beta-CNf60-61 (YP), beta CNf62-63 (FP), beta-CNf64-66 (GPI) and beta-CNf62-66 (FPGPI) were tentatively identified through high resolution MS/MS experiments; however, it was not possible to confirm if either milk protein or beta-casomorphins was a source releasing these peptides. Nonetheless, in this study peptides YP and GPI were released by L. delbrueckii ssp. bulgaricus. This is the first time GPI has been identified and thus future investigation of its bioactivity is warranted.

AB - Headspace gas chromatography mass spectrometry (HS-GC-MS) was used to measure changes in selected volatile flavour compounds in fresh banana during low temperature heat pump drying. Ten compounds from a range of chemical classes were measured during drying at three different drying conditions. Ester compounds were found to be the most affected, with losses varying from 25 to 87% during drying. Three patterns of depletion were observed in this study. Ester and aldehyde levels reduced quickly during the early stages of drying, but levels stabilised at non-zero values towards the end of drying; alcohol levels initially increased, then decreased and stabilised; whilst high molecular weight compounds, such as elemicine and eugenol, were not affected significantly. Selective diffusion and volatility affected the degree of flavour retention. PMID- 29580015 TI - Product involvement and consumer food-elicited emotional associations: Insights from emoji questionnaires. AB - Individual differences in food-related consumer behaviour are well documented, but lack thorough exploration in relation to product-elicited emotional associations. In this research, focus is directed to product involvement as a factor that modulates emotional associations to tasted products (dried fruit, n = 4) and written descriptions of consumption situations (drinking red wine, cooking dinner using seafood). Emoji questionnaires were used (as check-all-that-apply questions: CATA), and across two studies with consumers in New Zealand (n = 352) and China (n = 450), higher levels of involvement were associated with more positive emotional associations. For example, consumers with higher involvement for dried fruit used emoji with positive meanings (e.g., face savouring delicious food (), smiling face with heart-shaped eyes () and smiling face with smiling eyes () more frequently than those with lower levels of involvement. Conversely, emoji with negative or neutral meanings (e.g., confused face (), confounded face (), neutral face ()), were more frequently used by consumers with lower levels of product involvement. The number of significant differences between the samples of dried fruit were lower in the less involved consumer segment, and these consumers, on average, used less emoji to characterise the samples. A similar pattern of results were established for the written stimuli, which were used with Chinese consumers. For example, in the segment with greater involvement with seafood, associations to emoji with positive meanings were higher when responding to the situation "cooking dinner using frozen seafood as one of the ingredients." In the case of "drinking French red wine," the strategy used to define segments (median vs. triadic split of summed involvement scores) additionally influenced the results, and bigger differences were established when comparing more discrete segments (two extreme groups following triadic split).

Vascular endothelial growth factor (VEGF) is a secretedmolecule supporting angiogenesis in various cancers through activation of the PI3K/AKT/ERK1/2 pathway. OPN andVEGF have a number of isoforms with various activities. In spite of the well-defined association between OPN andVEGF isoform expression and cure rate for solid tumors, there is a scarcity of information as to any association inleukemia. Based on the critical role of OPN in cell survival, it seems reasonable to hypothesize that OPN and VEGFisoform expression levels may impact on chemoresistance and relapse in leukemia the same as in solid tumors. Hence,the aim of our review was to explain relationships between OPN and VEGF isoforms and angiogenesis and relatedpathways in chemoresistance of leukemia and solid tumors. Our findings demonstrated that OPNb and OPNc alongsidewith VEGF isoforms and other gene pathways are involved in angiogenesis and also might promote chemoresistanceand even recurrence in leukemia and solid tumors. To sum up, targeting OPN isoforms, particularly b and c, might bea novel therapeutic strategy for the treatment of leukemia as well as solid tumors. PMID- 29580030 TI - Knowledge, Attitudes and Practices Regarding Breast Cancer amongst Lebanese Females in Beirut AB - Objectives: Regular screening for breast cancer is associated with better survival, but compliance with guidelinesdepends on good knowledge and attitudes. This study aimed to assess the level of breast cancer knowledge, attitudesand screening practices in Lebanese females, and identify their socio-demographic determinants as well as barriers tomammography use. Methods: This cross-sectional study was conducted with 371 Lebanese females residing in Beirutaged 18-65 with no history of breast cancer. The questionnaire applied was adapted from Stager and Champion.The overall knowledge score was determined with sections on general knowledge, curability, symptoms, and screening;the overall attitude score concerned attitudes towards breast cancer, screening, and barriers; and the overall practicesscore was for breast self examination (BSE), clinical breast examination (CBE) and mammography. Bivariate andmultivariate analyses of socioeconomic determinants were performed for each score. Results: The mean knowledgescore was 55.5+/-17.1% and that for attitudes was 71.9+/-8.3%. For self examination, mammography and clinicalexamination practices, individual means were 45.7+/-42.3%, 77.9+/-36.5% and 29.1+/-45.5%, respectively. Knowledge,attitudes and practices correlated positively with each other (p<0.0001). The highest average was the knowledgeof symptoms (72.8+/-24.7%), and the lowest that of curability (49.6+/-25.7%). Most frequent barriers to mammographywere fear of learning bad news, pain, costs, and staff unpleasantness. Higher education was associated with betterknowledge (p=0.002) and smoking with lower levels (p=0.003). Older age (p=0.002), higher education (p=0.02),and taking exercise (p=0.02) were associated with better attitudes. Higher education (p=0.02) and having children(p=0.003) were associated with better practices. Conclusion: More emphasis should be placed on educating femaleson the curability of breast cancer and specific targeting of the barriers identified. PMID- 29580031 TI - Effects of an Educational Program for Prostate Cancer Prevention on knowledge and PSA Testing in Men Over 50Years old in Community Areas of Shiraz in 2016 AB - Background and Objectives: Prostate cancer was reported to be the second cause of cancer death in men in 2013.Studies have shown that those with higher knowledge levels are much more likely to undergo prostate cancer screening.The present study was aimed to determinate the effect of an educational program for prostate cancer prevention onknowledge and prostate-specific antigen (PSA) testing in men over 50 years old in community areas of Shiraz. Methods:This clinical trial was conducted among 93 men over 50 years old who were randomly divided into an intervention(n=48) and a control (n=45) group. The intervention group took part in an educational program focusing on theimportance of prostate cancer prevention with emphasis on cultural and economic issues. Data were collected usinga demographic information form, the Weinrich questionnaire for measuring the knowledge level about prostate cancerand screening, and also a researcher-made questionnaire covering reasons for not doing the test, before and 3 monthsafter the intervention. Additionally, participation in PSA testing was evaluated 3 months after the intervention. All datawere entered into the SPSS statistical software (version 14) and p<0.05 was considered to be statistically significant.Findings: The results showed that the intervention group's participation in PSA testing increased from 6.12% to 36.4%three months after the intervention. However, no significant change was observed in the control group. In addition,the intervention group's mean score of knowledge increased by about 2.69 points after the intervention, and a significantdifference was observed between the two groups in this regard (p<0.05). Conclusion: The results of the current studyrevealed effectiveness of the educational program in increasing the knowledge about prostate cancer and participationin PSA testing in men over 50 years of age. Hence, managers and authorities should execute plans to educate menregarding prostate cancer screening and promote their health status. PMID- 29580032 TI - Comparative Evaluation of a 6MV Flattened Beam and a Flattening Filter Free Beam for Carcinoma of Cervix - IMRTPlanning Study AB - Purpose: Intensity modulated radiotherapy (IMRT) plan quality, beam on time and integral dose were compared using6MV FB (Flattened Beam) and FFFB (Flattening filter free beam) for carcinoma of cervix. Materials and Methods:Ten patients with stage II-IIIB cervix cancer (Ca.Cx) were retrospectively identified from the department database.Target volume (TV) and organ at risk (OAR) were delineated as per Radiation Therapy Oncology Group (RTOG) cancerguidelines. Dose prescribed to planning target volume (PTV) was 50.4Gy in 28 fractions. Two plans (6MV FB IMRTand 6MV FFFB IMRT) were generated to achieve 95% of prescription dose to PTV and sparing OAR as per normaltissue guidelines. Numbers of beams and their orientations were the same for all plans. The homogeneity index (HI),conformity index (CI), treatment monitor unit (MU), beam on time (BOT) and non-tumor integral dose (NTID) werechosen for comparison. Results: FFFB generated plans were clinically acceptable. There was a statistically significantdifference among the FB IMRT and FFFB IMRT plans with respect to CI, HI, D50%, D2% in PTV coverage, bladderV50Gy, MU, mean NTID and non-tumor low dose volume. Conclusions: 6MV flattened and flattening filter free photonbeams produce comparable plans by IMRT . FFF beams allow time efficient treatment delivery and may help reducethe risk of secondary malignances in carcinoma cervix cases. PMID- 29580033 TI - Evaluation the Anti-Cancer Effect of PEGylated Nano-Niosomal Gingerol, on Breast Cancer Cell lines (T47D), In-Vitro AB - Background: Cancer is a significant problem in modern medicine, also is the most common cause of death aftercardiovascular diseases, and in need of targeted drug release. Although, chemotherapy is an important candidate incancer treatment, but it has many side effects on healthy tissues of the body. Therefore, Nano technology is usedfor specific function, by the least side effects and damage to normal cells. Materials and method: In this study, thepharmacological properties of PEGylated Nano-niosomal Gingerol was examined. Noisome were prepared using reversephase evaporation method, which contains specific proportion of cholesterol, span60 and polyethylene glycol. Then,PEGylated the prepared formulation by PEG6600. The amount of release and encapsulation of the drug was investigated.The percentage of remains of cancer cell line T47D treated with PEGylated niosomal Gingerol. Results: The averagediameter of the nanoparticles, size distribution and zeta potential were reported for PEGylated niosomal sample 35.65nm, 0.17 and 21 mv, and for PEGylated niosomal drug sample 256.9 nm, 0.23 and 28 mv, respectively. The amountof OD for encapsulated drug was 0.198, also the amount of concentration of the drug which is not encapsulated, was0.77947 MUl of the drug per ml. This value of encapsulated drug was 76.38 percent. Conclusion: The results showed thatIC50 of the formulation of PEGylated nanoniosomal Gingerol is less than the standard drug. It seems, the cause of thisphenomenon is due to the effect of Polyethylene glycol, in more stability and slower drug release, in the formulationof PEGylated niosome. Also, Polyethylene glycol makes increase in the drug dealing and its greater influence with thetarget cell. In this study, more than 76% of the Gingerol drug in PEGylated nanoniosomal formulation were enclose.Also, we could reduce the amount of drug release, as much as possible. PMID- 29580034 TI - Risk Factors, Biomarkers, Etiology, Outcome and Prognosis of Ischemic Stroke in Cancer Patients AB - Introduction: Cerebrovascular disease is the second most common complication in individuals with tumours.The aim of this study was to investigate risk factors, biomarkers, etiology and prognosis of ischemic stroke in cancerpatients (ISCPs). Methods: The medical records of 619 consecutive patients who were admitted with acute ischemicstroke from January 2012 to November 2014 were retrospectively evaluated. The patients were divided into two groups(group 1, patients with an active cancer prior to the onset of ischemic stroke; group 2, patients without an active cancerhistory). The demographic data, risk factors, NIHSS scores, thrombocyte count, D-dimer, fibrinogen and C reactiveprotein (CRP) level at admission, modified Rankin Scale (mRS) scores in the follow-up period and location of lesionson DWI were recorded. The Mann-Whitney U test, chi-squared test and logistic regression was used for analyzing data,p<0.05 being considered statistically significant. Results: A total of 46 (7.4%) ISCPs were included. Hyperlipidemiawas significantly lower in the ISCP group (p=0.001). Elevated thrombocyte counts, D-dimer, fibrinogen and CRP levelsat admission, acute multiple ischemic lesions, other causes, mortality in hospital and worse outcome were significantlyrelated to ISCP (p<0.05). On logistic regression analysis, follow up mRS>3, acute multiple ischemic lesions locatedin more than one vascular territory (AMIMCT) and other causes were significantly associated with ISCP (p<0.001).Conclusion: In our study, other causes, AMIMCT and mRS>3 were more common in the ISCP group. We consider thatCCS could be more suitable for detecting other causes than TOAST. Biomarkers could be important in the ISCP group. PMID- 29580035 TI - Fluorescence in Situ Hybridization (FISH) for Differential Diagnosis of Soft Tissue Sarcomas AB - Introduction:Soft tissue sarcomas are rare tumors comprising 1 percent of solid malignancies. The latest editionof WHO soft tissue pathology lists 94 benign and malignant soft tissue tumors. Many of these show a large degreeof morphological overlap. Immunohistochemistry has been shown to be reliable in many cases for differential diagnosisof lesions, although cytogenetic tests are considered the gold standard for many entities.Fluorescence in-situ hybridization(FISH) is a cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome whichhave a high degree of sequence complementarity. Many soft tissue tumors show recurrent genetic mutations that arenow being used as diagnostic markers. Knowledge of the molecular identity allows prediction of behavior, prognosisand treatment response. Objective:The aim of this study was to identify genetic mutations in soft tissue sarcomas usingFISH testing and to assess correlations with histological diagnosis. Material and methods:A total of 25 cases of differentsoft tissue sarcomas diagnosed on histology with the help of immunohistochemical staining and for which FISH studieswere requested were included in this study. Three pathologists with a special interest in soft tissue sarcomas reviewedthe cases. FISH tests for EWS, the X:18 translocation, FOXO1 and MDM2 were respectively applied for 8 cases ofEwing sarcoma, 8 cases of synovial sarcoma, 2 cases of rhabdomyosarcoma and 7 cases of dedifferentiated liposarcomaand atypical lipomatous tumors/well differentiated liposarcomas. Results:EWS gene fusion was detected in 7 out of8 cases of Ewing sarcoma and the X:18 translocation was positive in 3 of the 8 cases of synovial sarcoma. FOXO1was not detected in either of the two rhabdomyosarcomas. MDM2 by FISH was detected in only one out of 5 cases ofatypical lipomatous tumors and 1 out of 2 dedifferentiated liposarcomas. Conclusion: FISH is a useful adjunct in thediagnostic assessment of different types of soft tissue sarcomas. It is easy to set up, is relatively inexpensive and hasthe ability to diagnose sarcomas with great accuracy, especially in cases which can not be accurately classified evenafter thorough histological and immunohistochemical evaluation. It may play a very important role in the accuratediagnosis and correct management of patients. PMID- 29580036 TI - Clinical implication of hepatic volumetry for living donor liver transplantation. PMID- 29580037 TI - Analysis of the Expression of Surface Receptors on NK Cells and NKG2D on Immunocytes in Peripheral Blood of Patientswith Nasopharyngeal Carcinoma AB - Background: The aberrant expression of surface receptors on immunocytes may represent potential markers of tumorescape for nasopharyngeal carcinoma (NPC). The aim of this study was to investigate the expression of representativereceptors on natural killer (NK) cells and NK group 2, member D (NKG2D) on immunocytes in the peripheral bloodof patients with NPC. Methods: Patients (n = 64) with NPC prior to initiation of treatment were defined as the studygroup. Healthy volunteers (n = 31) served as the control group. The expression of NK cells and NKT cells; the triggeringreceptors NKp30, NKp44, and NKp46 on NK cells; the activating receptor NKG2D on NK cells, CD4+ T cells, andCD8+ T cells; and the inhibitory receptors CD158b and CD159a on NK cells were analyzed by flow cytometry in thetwo groups. Results: Here, our study showed that no differences were observed in terms of the numbers of NK cells orNKT cells, or the expression of CD158b and CD159a on the surface of NK cells between the two groups. Nevertheless,the expression levels of NKp30 and NKp46 on NK cells in the NPC patients were significantly lower than in the healthyindividuals (P < 0.05). No differences existed in the expression of NKG2D on NK cells, but NKG2D on CD8+ T cellsshowed a markedly lower expression in the study group (P < 0.001). Conclusions: Our findings may reflect a possiblemechanism of immune evasion for NPC. The enhancement of immunotherapy concerning NKp30, NKp46, and NKG2Dmay be an innovative treatment strategy for patients with NPC. PMID- 29580039 TI - Impact of Parents and Peers Smoking on Tobacco Consumption Behavior of University Students AB - Introduction: In the United Arab Emirates, smoking prevalence has increased in both sexes, especially amongyoung adults. Various factors have led to this catastrophe; examples include coverage on TV and social media, as wellas market availability. One major influence is smoking by parents and peers. A lot of students may start smoking becauseof the behavior of their family and friends, and therefore it is necessary to quantify adverse contributions. The aim ofthis project was to study to what degree parents and peers smoking habits may impact on smoking behavior of studentsat the University of Sharjah. Methods: This cross sectional observational study with a non-probability convenient typeof sampling, was conducted with university students aged 18 to 23. Information was collected using a self-administeredquestionnaire, comprising 23 questions, developed by ourselves. Results: A total of 400 University of Sharjah students(50% males and 50% females) were included.Some 15.8% of the smoking students had smoking parents, and 17.1%of them had smoking peers. The respective figures were 22.2% and 21.7% for males and 10% and 7.8% for females.Conclusions: Peers had a stronger impact than parents and both parents and peers had greater influence on males thanon females. Interestingly, almost 80% of the smoking students did not have smoking parents or peers, which leavesthe question unanswered of why they started smoking in the first place. Actions at a societal level should be taken intoconsideration to prevent smoking and thus help create a non-smoking generation. PMID- 29580038 TI - Epigenetic Downregulation and Growth Inhibition of IGFBP7 in Gastric Cancer AB - Background: Insulin-like growth factor-binding protein 7 (IGFBP7) has been found to be a tumor suppressorin several human cancers, but the role of IGFBP7 in gastric cancer has not yet been fully investigated. Herein, weexamined the epigenetic downregulation of IGFBP7 expression in gastric cancer. Methods: Expression and methylationof IGFBP7 in gastric cancer cells and primary gastric cancer patients were determined using qRT-PCR, western blot,immunohistochemistry, and methylation specific-PCR, respectively. The effects of IGFBP7 on gastric cancer cellswere investigated by various experimental conditions, such as proliferation, colony formation, apoptosis, invasion,and migration assay. Results: IGFBP7 methylation was inversely correlated with IGFBP7 expression in gastriccancer. Univariate and multivariate analysis showed that IGFBP7 expression and tumor stage were independentprognostic factors. IGFBP7 knockdown increased gastric cancer cell growth, invasion, and migration, whereas IGFBP7overexpression in gastric cancer cells induced cell growth inhibition and apoptosis. Conclusion: Our data suggest thatIGFBP7 functions as a tumor suppressor in gastric cancer via an epigenetic pathway.

The effect of a GnRH antagonist synchronous to chemotherapy, which might protect spermatogenesisby halting cell division in spermatogenic cells, was also investigated. Method and Materials: A total of 30 adult malemice were studied in three equal groups of ten. In the V group, a single dose of the chemotherapy drug vincristine wasinjected intraperitonally at 1.5 mg/kg. In the V+C, group, the injection of Cetrorelix was started, and one week beforeto one week after vincristine injection continued ( for 3 weeks). Controls received no treatment. Samples were takenfrom the testicles, and fixed in Boueins fixative for light microscopy. Results: Comparing the mean number of Sertoliand spermatogony cells and the rate of spermatogenesis index (SI) in the V group with controls showed significantdifferences,which were not evident in the V+C group. Conclusion: According to the results, the cetrorelix antagonist(GnRH) could largely prevent side effects of vincristine administration regarding seminiferous tubules.

Serumlevels were compared between patients with salivary gland tumors and healthy control. A total of 105 patients wereenrolled in the study (55 men, 50 women). Result: Mean age was 45.5 years. Thirty-nine patients with malignant and66 cases with benign tumors were compared with 56 healthy participants with a mean age of 51.7. No statisticallysignificant differences were observed when comparing GAL-3 serum levels between malignant and benign salivary glandtumor patients, but a statistically significant difference was found between case and control patients with p-values of0.02. Serum levels of galectin-3 protein were elevated in patients with salivary gland cancer compared with the healthypopulation. Conclusion: The difference between benign and malignant tumor patients was significant, but revealedno clinic pathological characteristics in malignant tumors. To the best of the authors' knowledge, this is the first timea study suggests that GAL-3 serum levels could help clinicians screen for salivary gland cancer.

Since co stimulatory molecule expression may be affected by genepolymorphisms, we aimed to investigate associations between variants of PD.1 and ICOS and susceptibility to coloncancer. Material and methods: ICOS (-693A/G), ICOS (+1720C/T) and PD.1 ( 538G/A) gene polymorphisms wereevaluated by the PCR-RFLP method in 76 colon cancer patients and 73 healthy controls. Results: The frequenciesof the GG genotype and the G allele at position -693 of the ICOS gene were significantly higher in the patient group(P=0.014 and p=0.0002), while the AA genotype was significantly more common in controls (P=0.0016). At position-538 of PD.1, GG genotype and G allele frequencies were higher in the patient group (P<0.0001and P<0.0001). Again,AA and also AG genotypes significantly predominated in controls (P<0.0001 and P=0.012). Regarding genotypesand alleles of ICOS at position +1720. Frequencies of GCG and GTG haplotypes were higher in patients comparedto those of controls (P=0.016 and P<0.0001), while, frequencies of GTA, ATA and ATG haplotypes were higher incontrols (P=0.0017, P<0.0001 and P=0.015). GTG/GTG and GTG/GCG double haplotypes were more frequent inpatients compared to controls (P=0.0147 and P=0.0071). Conclusion: Our study clarified that PD.1 (-538G/A) andICOS (-693A/G) gene polymorphisms can be considered as genetic risk factors for the development of colon canceramong Iranian patients.

Although use of the prostate specific antigen (PSA) asa diagnostic marker has improved the detection and management of PCa, low specificity and sensitivity has limited itsclinical efficacy. Moreover, elevated PSA is frequently observed in benign prostate hyperplasia (BPH). Mean plateletvolume (MPV) and platelet distribution width (PDW) are commonly used indicators of platelet activation. The purposeof current study was to investigate the ability of PSA, MPV, and PDW individually or in combination, to differentiatePCa from BPH. Materials and Methods: This study included 100 patients with PCa and 108 patients with BPH. Wecollected all participants' clinical and laboratory characteristics. The benefit of adding MPV and PDW to a modelwith only PSA was evaluated as an increased in the area under the curve (AUC) obtained by receiver operating curve(ROC). Results: PCa patients had reduced MPV and elevated PSA and PDW levels compared to BPH patients. Singlebiomarkers had AUC values ranging from 0.683 for PDW to 0.865 for PSA. Moreover, the combination of PSA, MPV,and PDW increased the AUC to 0.935 (0.892-0.964) (p<0.0001), significantly higher than those of any single marker.Conclusions: The combined use of PSA, MPV, and PDW may be clinically useful in distinguishing between PCa andBPH. PMID- 29580044 TI - Alcohol Consumption as a Risk Factor for Breast Cancer Development: A Case Control Study in Brazil AB - Background: Alcohol consumption is a well-established risk factor for breast cancer, but the evidence is mostlyfrom developed countries. Brazil is going through a rapid demographic expansion, and studies of this relationship arealso needed in such unexplored settings. Methods: We assessed the relationship between alcohol consumption andbreast cancer risk among 1,506 Brazilian women (406 cases and 1,100 controls). Regression models were used tocalculate odds ratios (OR) and 95% confidence intervals (CI). All statistical tests were two-tailed. Results: The meanage of the 1,506 women was 42.0 (standard deviation, +/-15.0) years. There was a significant association between breastcancer and age, body mass index, age at menarche, menstrual flow and menstrual cycle. Multivariate analysis showedan increased risk of invasive breast cancer in regular alcohol consumers (<50 years old: OR 4.7; 95% CI 1.4-16.2; >=50years old: OR 3.9; 95% CI 1.2-13.4) compared with abstainers or occasional drinkers. Women with a regular alcoholintake for 10 years or more who were less than 50 years old had a threefold higher risk of developing breast cancer(OR 3.0; 95% CI 1.2-7.6). Conclusion: Regular alcohol consumption increases the risk of breast cancer mainly amongwomen less than 50 years old.

Cancer incidence data gathered for different organs wereprocessed through cleaning, integration, transformation, reduction and mining for ultimate representation. Risk ofcancer appeared to be continuously increasing among both males and females. Overall, lymphomas and breast cancerare the most common neoplasm in males and females, respectively, in Lahore with almost the highest rates in the AsianPacific region. The incidence of head and neck, brain, and lung cancers, as well as leukemia have rapidly increasedamong males, whereas, ovarian, cervix, head and neck and lymphomas have become more common among females.The present communication should be helpful for adequate strategic planning, identification of risk factors and takingappropriate prevention and control measures at the national level. PMID- 29580046 TI - Initial clinical outcomes of proton beam radiotherapy for hepatocellular carcinoma. AB - PURPOSE: This study aimed to evaluate the initial outcomes of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in terms of tumor response and safety. MATERIALS AND METHODS: HCC patients who were not indicated for standard curative local modalities and who were treated with PBT at Samsung Medical Center from January 2016 to February 2017 were enrolled. Toxicity was scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was evaluated using modified Response Evaluation Criteria in Solid Tumors (mRECIST). RESULTS: A total of 101 HCC patients treated with PBT were included. Patients were treated with an equivalent dose of 62-92 GyE10. Liver function status was not significantly affected after PBT. Greater than 80% of patients had Child-Pugh class A and albumin-bilirubin (ALBI) grade 1 up to 3-months after PBT. Of 78 patients followed for three months after PBT, infield complete and partial responses were achieved in 54 (69.2%) and 14 (17.9%) patients, respectively. CONCLUSION: PBT treatment of HCC patients showed a favorable infield complete response rate of 69.2% with acceptable acute toxicity. An additional follow-up study of these patients will be conducted. PMID- 29580047 TI - The feasibility of shear wave elastography for diagnosing superficial benign soft tissue masses. AB - Purpose: The purpose of this study was to investigate the feasibility of shear wave ultrasound elastography for differentiating superficial benign soft tissue masses through a comparison of their shear moduli. Methods: We retrospectively analyzed 48 masses from 46 patients from February 2014 to May 2016. Surgical excision, fine-needle aspiration, and clinical findings were used for the differential diagnosis. The ultrasonographic examinations were conducted by a single musculoskeletal radiologist, and the ultrasonographic findings were reviewed by two other radiologists who were blinded to the final diagnosis. Conventional ultrasonographic features and the median shear modulus were evaluated. We compared the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors using the Kruskal-Wallis test. Additionally, the Mann-Whitney U test was used to compare two distinct groups. Results: Significant differences were found in the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors (23.7, 5.8, and 9.2 kPa, respectively, P=0.019). Epidermoid cysts showed a greater median shear modulus than ganglion cysts (P=0.014) and lipomatous tumors (P=0.049). Conclusion: Shear wave elastography may contribute to the differential diagnosis of superficial benign soft tissue masses through a direct quantitative analysis.

AB - Hydraulic fracturing is an increasingly common technique for the extraction of natural gas entrapped in shale formations. This technique has been highly criticized due to the possibility of environmental contamination, underscoring the need for method development to identify chemical factors that could be utilized in point-source identification of environmental contamination events. Here, we utilize comprehensive two-dimensional gas chromatography (GC * GC) coupled to high-resolution time-of-flight (HRT) mass spectrometry, which offers a unique instrumental combination allowing for petroleomics hydrocarbon fingerprinting. Four flowback fluids from Marcellus shale gas wells in geographic proximity were analyzed for differentiating factors that could be exploited in environmental forensics investigations of shale gas impacts. Kendrick mass defect (KMD) plots of these flowback fluids illustrated well-to-well differences in heteroatomic substituted hydrocarbons, while GC * GC separations showed variance in cyclic hydrocarbons and polyaromatic hydrocarbons among the four wells. Additionally, generating plots that combine GC * GC separation with KMD established a novel data-rich visualization technique that further differentiated the samples.

AB - Nuclear power is a relatively carbon-free energy source that has the capacity to be utilized today in an effort to stem the tides of global warming. The growing demand for nuclear energy, however, could put significant strain on our uranium ore resources, and the mining activities utilized to extract that ore can leave behind long-term environmental damage. A potential solution to enhance the supply of uranium fuel is to recover uranium from seawater using amidoximated adsorbent fibers. This technology has been studied for decades but is currently plagued by the material's relatively poor selectivity of uranium over its main competitor vanadium. In this work, we investigate the binding schemes between uranium, vanadium, and the amidoxime functional groups on the adsorbent surface. Using quantum chemical methods, binding strengths are approximated for a set of complexation reactions between uranium and vanadium with amidoxime functionalities. Those approximations are then coupled with a comprehensive aqueous adsorption model developed in this work to simulate the adsorption of uranium and vanadium under laboratory conditions. Experimental adsorption studies with uranium and vanadium over a wide pH range are performed, and the data collected are compared against simulation results to validate the model. It was found that coupling ab initio calculations with process level adsorption modeling provides accurate predictions of the adsorption capacity and selectivity of the sorbent materials. Furthermore, this work demonstrates that this multiscale modeling paradigm could be utilized to aid in the selection of superior ligands or ligand compositions for the selective capture of metal ions. Therefore, this first-principles integrated modeling approach opens the door to the in silico design of next-generation adsorbents with potentially superior efficiency and selectivity for uranium over vanadium in seawater. PMID- 29580050 TI - Indirect X-ray Detectors Based on Inkjet-Printed Photodetectors with a Screen Printed Scintillator Layer. AB - Organic photodetectors (PDs) based on printing technologies will allow to expand the current field of PD applications toward large-area and flexible applications in areas such as medical imaging, security, and quality control, among others. Inkjet printing is a powerful digital tool for the deposition of smart and functional materials on various substrates, allowing the development of electronic devices such as PDs on various substrates. In this work, inkjet printed PD arrays, based on the organic thin-film transistor architecture, have been developed and applied for the indirect detection of X-ray radiation using a scintillator ink as an X-ray absorber. The >90% increase of the photocurrent of the PDs under X-ray radiation, from about 53 nA without the scintillator film to about 102 nA with the scintillator located on top of the PD, proves the suitability of the developed printed device for X-ray detection applications. PMID- 29580051 TI - General Theory of Absorption in Porous Materials: Restricted Multilayer Theory. AB - In this article, we present an approach for the generalization of adsorption of light gases in porous materials. This new theory goes beyond Langmuir and Brunauer-Emmett-Teller theories, which are the standard approaches that have a limited application to crystalline porous materials by their unphysical assumptions on the amount of possible adsorption layers. The derivation of a more general equation for any crystalline porous framework is presented, restricted multilayer theory. Our approach allows the determination of gas uptake considering only geometrical constraints of the porous framework and the interaction energy of the guest molecule with the framework. On the basis of this theory, we calculated optimal values for the adsorption enthalpy at different temperatures and pressures. We also present the use of this theory to determine the optimal linker length for a topologically equivalent framework series. We validate this theoretical approach by applying it to metal-organic frameworks (MOFs) and show that it reproduces the experimental results for seven different reported materials. We obtained the universal equation for the optimal linker length, given the topology of a porous framework. This work applied the general equation to MOFs and H2 to create energy-storage materials; however, this theory can be applied to other crystalline porous materials and light gases, which opens the possibility of designing the next generations of energy-storage materials by first considering only the geometrical constraints of the porous materials. PMID- 29580052 TI - High Selectivity Toward C2H4 Production over Cu Particles Supported by Butterfly Wing-Derived Carbon Frameworks. AB - Converting carbon dioxide to useful C2 chemicals in a selective and efficient manner remains a major challenge in renewable and sustainable energy research. Herein, we adopt butterfly wings to assist the preparation of an electrocatalyst containing monodispersed Cu particles supported by nitrogen-doped carbon frameworks for an efficient reduction of CO2. Benefiting from structure advantages and the synergistic effect between nitrogen dopants and stepped surface-rich Cu particles, the resulting catalyst exhibited a high faradic efficiency of 63.7 +/- 1.4% for ethylene production (corresponding to an ethylene/methane products' ratio of 57.9 +/- 5.4) and an excellent durability (~100% retention after 24 h). This work presents some guidelines for the rational design and accurate modulation of metal heterocatalysts for high selectivity toward ethylene from CO2 electroreduction. PMID- 29580053 TI - Occurrence of Glucocorticoids, Mineralocorticoids, and Progestogens in Various Treated Wastewater, Rivers, and Streams. AB - In the current study a high sensitive analytical method was developed for the determination of 60 steroids including glucocorticoids (GC), mineralocorticoids (MC), and progestogens (PG) in WWTP effluents and surface water using liquid chromatography with tandem mass spectrometry detection (LC-MS/MS). The limits of quantification (LOQ) ranged between 0.02 ng/L (cortisone) to 0.5 ng/L (drospirenone) in surface water and from 0.05 ng/L (betamethasone) to 5 ng/L (chlormadinone) in treated wastewater. After optimization, the developed method was applied to WWTP effluents, rivers, and streams around Germany. Numerous steroids have been detected during the sampling campaign and predominant analytes from all steroid types were determined. Moreover, the occurrence of dienogest, mometasone furoate, flumethasone pivalate, and the metabolites 6beta-hydroxy dienogest, 6beta-hydroxy triamcinolone acetonide, 7alpha-thiomethyl spironolactone, and 11alpha-hydroxy canrenone is reported for the first time. In addition, this study revealed the ubiquitous presence of topically applied GC monoesters betamethasone propionate, betamethasone valerate, and 6alpha methylprednisolone propionate in WWTP effluents and surface water.

AB - Bifacial semitransparent inverted planar structured perovskite solar cells (PSCs) based on Cs0.05FA0.3MA0.7PbI2.51Br0.54 using an Ag thin film electrode and V2O5 optical coupling layer are investigated theoretically and experimentally. It is shown that the introduction of the cesium (Cs) ions in the perovskite could obviously improve the device performance and stability. When only the bare Ag film electrode is used, the PSCs show a bifacial performance with the power conversion efficiency (PCE) of 14.62% illuminated from the indium tin oxide (ITO) side and 5.45% from the Ag film side. By introducing a V2O5 optical coupling layer, the PCE is enhanced to 8.91% illuminated from the Ag film side, which is 63% improvement compared with the bare Ag film electrode, whereas the PCE illuminated from the ITO side remains almost unchanged. Moreover, when a back reflector is employed, the PCE of device could be further improved to 15.39% by illumination from the ITO side and 12.44% by illumination from the Ag side. The devices also show superior semitransparent properties and exhibit negligible photocurrent hysteresis, irrespective of the side from which the light is illuminated. In short, the Ag/V2O5 double layer is a promising semitransparent electrode due to its low cost and simple preparation process, which also point to a new direction for the bifacial PSCs and tandem solar cells. PMID- 29580056 TI - Study of the Gemini Surfactants' Self-Assembly on Graphene Nanosheets: Insights from Molecular Dynamic Simulation. AB - Understanding the mechanism of adsorption and self-assembly of surfactants on graphene is highly important to perform better optimization of the graphene dispersion process. Because of Gemini surfactants' special structure, they have a high charge capacity, high hydrophobicity, and unique self-assembly properties compared to single-chain surfactants. Therefore, Gemini surfactants with their small concentrations are expected to disperse and stabilize graphene nanosheets in aqueous solutions more effectively. We conducted molecular dynamics simulations to study adsorption and self-assembly of single-chain cationic surfactant dodecyltrimethylammonium bromide (C12TAB) and its same family Gemini surfactant dimethylene-alpha,beta-bis(dodecyldimethylammonium bromide) ([12-2 12]Br2) on graphene nanosheets. The results showed that assemblies morphology formed on graphene is affected by surfactant structure. We observed that increasing surface coverage, especially for [12-2-12]Br2, leads to a transmission in adsorption mechanism and most [12-2-12]Br2 head groups tend toward the aqueous phase and prevent water molecules from accessing graphene surface. It can be concluded from morphological assessments that [12-2-12]Br2 is more effective than C12TAB in stabilizing graphene aqueous suspensions. Moreover, we investigated the effect of graphene sheet size and Gemini surfactant spacer length on the structure of surfactant assemblies on graphene. The present study results can expand our comprehension of dispersion mechanism of graphene nanosheets by Gemini surfactants. PMID- 29580055 TI - Gate-Induced Metal-Insulator Transition in MoS2 by Solid Superionic Conductor LaF3. AB - Electric-double-layer (EDL) gating with liquid electrolyte has been a powerful tool widely used to explore emerging interfacial electronic phenomena. Due to the large EDL capacitance, a high carrier density up to 1014 cm-2 can be induced, directly leading to the realization of field-induced insulator to metal (or superconductor) transition. However, the liquid nature of the electrolyte has created technical issues including possible side electrochemical reactions or intercalation, and the potential for huge strain at the interface during cooling. In addition, the liquid coverage of active devices also makes many surface characterizations and in situ measurements challenging. Here, we demonstrate an all solid-state EDL device based on a solid superionic conductor LaF3, which can be used as both a substrate and a fluorine ionic gate dielectric to achieve a wide tunability of carrier density without the issues of strain or electrochemical reactions and can expose the active device surface for external access. Based on LaF3 EDL transistors (EDLTs), we observe the metal-insulator transition in MoS2. Interestingly, the well-defined crystal lattice provides a more uniform potential distribution in the substrate, resulting in less interface electron scattering and therefore a higher mobility in MoS2 transistors. This result shows the powerful gating capability of LaF3 solid electrolyte for new possibilities of novel interfacial electronic phenomena. PMID- 29580057 TI - Design, Synthesis, and Preliminary Evaluation of SPECT Probes for Imaging beta Amyloid in Alzheimer's Disease Affected Brain. AB - In this study, we synthesized of a series of 2-phenyl- and 2-pyridyl-imidazo[1,2- a]pyridine derivatives and examine their suitability as novel probes for single photon emission computed tomography (SPECT)-based imaging of beta-amyloid (Abeta). Among the 11 evaluated compounds, 10 showed moderate affinity to Abeta(1 42) aggregates, exhibiting half-maximal inhibitory concentrations (IC50) of 14.7 +/- 6.07-87.6 +/- 39.8 nM. In vitro autoradiography indicated that 123I-labeled triazole-substituted derivatives displayed highly selective binding to Abeta plaques in the hippocampal region of Alzheimer's disease (AD)-affected brain. Moreover, biodistribution studies performed on normal rats demonstrated that all 123I-labeled probes featured high initial uptake into the brain followed by a rapid washout and were thus well suited for imaging Abeta plaques, with the highest selectivity observed for a 1 H-1,2,3-triazole-substituted 2-pyridyl imidazopyridine derivative, [123I]ABC577. This compound showed good kinetics in rat brain as well as moderate in vivo stability in rats and is thus a promising SPECT imaging probe for AD in clinical settings.

AB - The acetonitrile-water mixture is one of the most commonly used solvents in hydrophilic interaction chromatography, which contains silica as the solid phase. As such, the silica/acetonitrile-water interface plays a large role in the separation of compounds. Varying the pH is one way to influence retention times, particularly of ionizable solutes, yet the influence of high pH is often unpredictable. To determine how the structure of this interface changes with pH, we utilized the surface specific technique sum frequency generation (SFG). Previous SFG studies at neutral pH have suggested the existence of acetonitrile bilayers at the aqueous silica interface even at low acetonitrile mole fractions. Here we find that the SFG signal from 2900 to 3040 cm-1 at the silica/acetonitrile-water interface increased as we adjusted the aqueous pH from near neutral to high values. This increase in signal was attributed to a greater amount of aligned water which is consistent with an increase in silica surface charge at high pH. In contrast, complementary measurements of the silica/acetonitrile-deuterium oxide interface revealed that the acetonitrile methyl mode nearly vanished as the aqueous pH was increased. This loss of methyl mode signal is indicative of a decrease in the number density of acetonitrile molecules at the interface, as orientation analysis indicates no significant change in the net orientation of the outer leaflet of the acetonitrile bilayer over the pH range studied. PMID- 29580059 TI - Adsorbed Layer Thickness Determination for Convective-Based Media from Pressure Drop Data. AB - In the present work, we derive a theoretical framework to determine the adsorbed layer thickness from pressure drop measurements for convective-based media without any assumptions about the geometry of the pore structure of the stationary phase matrix. Equations are presented to calculate accuracy of the estimated adsorbed layer thickness as a consequence of measurement error and approximations of the mathematical model. We discovered that there is a minimum in the error for certain pressure drops that results in optimal experimental conditions for determining the adsorbed layer thickness. We demonstrate that the adsorbed layer thickness can be determined with less than 10% error using a wide range of experimental conditions simply from pressure drop data. By careful selection of porous bed dimensions and flow rates, the adsorbed layer thicknesses from subnanometer dimensions up to several hundred nanometers can be determined by measurement of the pressure drop in a range of several bars. The method was experimentally tested on methacrylate monolithic columns using monodisperse latex nanoparticles as a reference standard and two different proteins as unknowns demonstrating close agreement with calculations.

AB - INTRODUCTION: Diabetes prevalence in Scotland is 5.3%, with type 2 diabetes accounting for 86.7% of all cases in the National Health Service Highlands health board area and 85.7% in the Western Isles. Structured education is a key component in the management of this chronic disease. However, current group session models are less feasible in lower-population non-urban environments due to distance, participant numbers and access to appropriately trained healthcare professionals. Group sessions may also be a less attractive option in small communities, where people tend to have close day-to-day personal contact. This study assesses the access and delivery preferences of remote and rural service users in the Highlands and Western Isles to structured diabetes education programs. METHODS: The study used a mixed methods approach of focus groups and questionnaires with people with type 2 diabetes in the Highlands and Islands of Scotland. Both modes of participation were designed to explore perception of diabetes knowledge, diabetes education and use of technology. RESULTS: One-to-one delivery was the delivery method of choice; however, there was a preference for a digital approach over group education sessions. Service users expressed a strong desire to be able to learn at their own pace, when and where they wanted to, and with no requirement to travel. To address these requirements an online resource, providing access to both learning sessions and trusted sources of information, was the preferred mode of delivery. CONCLUSIONS: People with type 2 diabetes living in remote and rural areas of the Scottish Highlands and Islands who already use the internet are receptive to the use of digital technology for delivery of diabetes education and are interested in learning more about management of their condition through this medium. They believe that a technology approach will provide them with more control over the pace of learning, and where and when this learning can take place. PMID- 29580063 TI - Ambient air pollution and cardiovascular diseases: From bench to bedside. AB - Air pollution has a great impact on health, representing one of the leading causes of death worldwide. Previous experimental and epidemiological studies suggested the role of pollutants as risk factors for cardiovascular diseases. For this reason, international guidelines included specific statements regarding the contribution of particulate matter exposure to increase the risk of these events. In this review, we summarise the main evidence concerning the mechanisms involved in the processes linking air pollutants to the development of cardiovascular diseases.

AB - Rifaximin, an oral antimicrobial, has many advantages because it is selective intestine, has minimal adverse effects and is used for the treatment of some diseases such as hepatic encephalopathy, irritable bowel syndrome, travelers' diarrhea, ulcerative colitis, Clostridium difficile and acute diarrhea. Rifaximin in the form of 200 mg tablets is commercially available. The crystalline alpha form is therapeutically safe and effective. In most of the official compendia, rifaximin has no monograph and in none of them is there a monograph for rifaximin tablets. The literature, however, contemplates this gap with varied methods. The literature presents some methods for evaluation of rifaximin in both biological fluid and pharmaceutical product. High performance liquid chromatography stands out for the evaluation of rifaximin. Most of the methods reported in the literature are for pharmaceuticals products. They use (1) toxic organic solvents, harmful to the operator and the environment, and/or (2) buffer solution, which has a shorter service life and requires time-consuming washes of the chromatographic system generating more waste. So, this work aims to discuss (i) properties; (ii) applications; (iii) polymorphism and (iv) analytical methods of rifaximin by the look of green chemistry. This review shows an extremely current topic of great importance to the chemical-pharmaceutical area and everything it involves, since the analytical process until the impact on the environment in which it is embedded.

AB - Compared with other types of packaging, edible coatings are becoming more and more popular because of their more environmentally friendly properties and active ingredients carrying ability. The edible coating can reduce the influence of essential oils (EOs) on the flavor of the product and also can prolong the action time of EOs through the slow-release effect, which effectively promote the application of EOs in food. Understanding the different combinations of edible coatings and EOs as well as their antimicrobial effects on different microorganisms will be more powerful and targeted to promote the application of EOs in real food systems. The review focus on the contribution of the combination of EOs and edible coatings (EO-edible coatings) to prolong the shelf life of food products, (1) specifically addressing the main materials used in the preparation of EO-edible coatings and the application of EO-edible coatings in the product, (2) systematically summarizing the main production method of EO-edible coatings, (3) discussing the antiseptic activity of EO-edible coatings on different microorganisms in food. PMID- 29580067 TI - Migraine is common in patients with sarcoidosis. AB - OBJECTIVE: To describe the frequency of migraine and predictors of having migraine in sarcoidosis patients. METHODS: The ID migraine questionnaire was administered to a well-phenotyped observational cohort of sarcoidosis patients (most of whom were seeking specialty care) and healthy controls. Predictors of migraine status were examined using univariate and multivariable logistic regression. RESULTS: Migraine was seen in 29% of 96 patients with sarcoidosis and 13% of 39 healthy controls, ( p = 0.049). Among those with sarcoidosis, in univariate regression analysis only female sex was predictive of having migraine, and in a multivariable regression female sex remained significant (OR 4.6, 95% CI 1.2-18.2). There was no association between migraine and age, depression, dyspnea, immunosuppression use, or ESR. CONCLUSIONS: Migraine is a common comorbidity in sarcoidosis patients. As such, better recognition and targeted treatment of migraine has the potential to improve quality of life as part of a comprehensive care plan for sarcoidosis patients.

AB - It is widely recognized that abdominal pain and discomfort are common problems in the United States and are often associated with negative quality of life. The prevalence of anxiety/depression elevations and disorders among persons with gastrointestinal disturbances (GI) is estimated to be at least two to three times the rate in the general population. Visceral sensitivity reflects anxiety about GI sensations and its accompanying contexts and often leads to worsening of sensations (e.g. bloating, upset stomach, diarrhea). Among individuals with GI symptoms, visceral sensitivity may be associated with interpreting common sensations as catastrophic which may be related to greater difficulties with emotion dysregulation (e.g. severe anxiety and depression). The current study evaluated the indirect association of visceral sensitivity via emotion dysregulation in relation to depression, anxious arousal, and social anxiety symptoms among 344 young adults with a current history of GI symptoms and problems. Results indicated an indirect effect of visceral sensitivity via emotion dysregulation. These findings provide novel empirical support for the association of visceral sensitivity with emotional distress symptoms among young adults with GI symptoms. Based on the results, targeting emotion dysregulation may be a promising health promotion tactic among young adults with GI symptoms and disorders. PMID- 29580070 TI - Circadian gene methylation profiles are associated with obesity, metabolic disturbances and carbohydrate intake. AB - The circadian clock regulates the daily rhythms of several physiological and behavioral processes. Disruptions in clock genes have been associated with obesity and related comorbidities. This study aimed to analyze the association of DNA methylation signatures at circadian rhythm pathway genes with body mass index (BMI), metabolic profiles and dietary intakes. DNA methylation profiling was determined by microarray in white blood cells from 474 adults from the Methyl Epigenome Network Association (MENA) project. Kyoto Encyclopedia of Genes and Genomes database was used to identify the genes integrating the circadian rhythm pathway. Network enrichment analyses were performed with the PathDIP platform. Associations between circadian methylation patterns with anthropometric measurements, the metabolic profile, clinical data and dietary intakes were analyzed. DNA methylation patterns of nine CpG sites at six circadian rhythm pathway genes were strongly correlated with BMI (false discovery rates <0.0001). These CpGs encompassed cg09578018 (RORA), cg20406576 (PRKAG2), cg10059324 (PER3), cg01180628 (BHLHE40), cg23871860 (FBXL3), cg16964728 (RORA), cg14129040 (CREB1), cg07012178 (PRKAG2) and cg24061580 (PRKAG2). Interestingly, network enrichment analyses revealed that the six BMI-associated genes statistically contributed to the regulation of the circadian rhythm pathway (p = 1.9E-10). In addition, methylation signatures at cg09578018 (RORA), cg24061580 (PRKAG2), cg01180628 (BHLHE40) and cg10059324 (PER3) also correlated with insulin resistance (p < 0.0001) and mean arterial blood pressure (p < 0.0001). Furthermore, relevant correlations (p < 0.05) between methylation at cg09578018 (RORA) and cg01180628 (BHLHE40) with total energy and carbohydrate intakes were found. This investigation revealed potential associations of DNA methylation profiles at circadian genes with obesity, metabolic disturbances and carbohydrate intake, with potential impact on weight homeostasis.

AB - The aim of this study was to compare metabolic aspects potentially associated with metabolic syndrome (MetS), in addition to serum leptin levels and sleep, according to exposure to night work among nursing staff. A cross-sectional study involving 60 nursing staff was conducted. Sociodemographic, sleep (Karolinska Sleep Questionnaire), physical activity (International Physical Activity Questionnaire), and nutrition data (16-Food Intake Questionnaire) were collected. Body measurements and blood pressure were taken and blood collected to determine glycemia, total cholesterol and portions of low-density lipoprotein and high density lipoprotein and triglycerides, and leptin levels. The sample was divided into three groups according to exposure to night work (nonexposed, currently exposed, past exposure). Furthermore, to evaluate the relationship between exposure time and prevalence of MetS, the night-exposed groups (past and current) were divided according to time exposed to night shifts (<10 years and >=10 years). Mean age of participants was 39.8 +/- 10.5 years. The groups were homogenous with regard to sociodemographic characteristics, physical activity, dietary patterns, and health aspects. The prevalence of MetS in the population studied was 32%, above the rate for the general population. However, there were no significant differences among the groups. In addition, a higher proportion of participants with hypertriglyceridemia and diastolic arterial hypertension was observed in the currently exposed group. The currently exposed group also reported less sleep and higher sleep debt than the other groups on workdays. Although no differences were observed among the groups regarding MetS, the currently exposed group had more sleep disturbances than the others, and a higher prevalence of two out of three risk factors for the MetS diagnosis. PMID- 29580072 TI - Bright light exposure before bedtime impairs response inhibition the following morning: a non-randomized crossover study. AB - INTRODUCTION: Bright light exposure in the late evening can affect cognitive function the following morning either by changing the biological clock and/or disturbing sleep, but the evidence for this effect is scarce, and the underlying mechanism remains unknown. In this study, we first aimed to evaluate the effect of bright light exposure before bedtime on frontal lobe activity the following morning using near-infrared spectroscopy (NIRS) during a Go/NoGo task. Second, we aimed to evaluate the effects of bright light exposure before bedtime on polysomnographic measures and on a frontal lobe function test the following morning. METHODS: Twenty healthy, young males (mean age, 25.5 years) were recruited between September 2013 and August 2014. They were first exposed to control light (150 lux) before bedtime (from 20:00 h to 24:00 h) for 2 days and then to bright light (1,000 lux) before bedtime for an additional 5 days. We performed polysomnography (PSG) on the final night of each light exposure period (on nights 2 and night 7) and performed NIRS, which measures the concentrations of oxygenated and deoxygenated hemoglobin (OxyHb and DeoxyHb, respectively), coupled with a Go/NoGo task the following morning (between 09:30 h and 11:30 h). The participants also completed frontal lobe function tests the following morning. RESULTS: NIRS showed decreased hemodynamic activity (lower OxyHb and a tendency toward higher DeoxyHb concentration) in the right frontal lobe during the NoGo block after 1000-lux light exposure compared with that during the NoGo block after 150-lux light exposure. The commission error rate (ER) during the Go/NoGo task was higher after 1000-lux light exposure than that during the Go/NoGo task after 150-lux light exposure (1.24 +/- 1.09 vs. 0.6 +/- 0.69, P = 0.002), suggesting a reduced inhibitory response. CONCLUSION: This study shows that exposure to bright light before bedtime for 5 days impairs right frontal lobe activation and response inhibition the following morning. PMID- 29580073 TI - The Effects of the Perception of Being Recognized by Patients With Alzheimer Disease on a Caregiver's Burden and Psychophysical Health. AB - Caring for a patient with Alzheimer disease (AD) represents a real challenge that can have considerable long-term psychological and physical consequences. The aim of this study was to evaluate the impact of the perception of being recognized on both the psychophysical health and the level of burden reported in caregivers of patients with AD. The secondary aim was to evaluate the association between the use of a home care assistance service and the burden and psychophysical health in caregivers. The Caregiver Burden Inventory (CBI), the 36-item Short-Form Health Survey (SF-36), and a visual analog scale (VAS) to evaluate the level of perception of being recognized were administered to 31 caregivers of patients with AD. Data were also collected from patients with AD using the Mini-Mental State Examination (MMSE). The level of perception of being recognized was significantly and negatively correlated with total burden ( r = -0.36; P = .045) and objective burden ( r = -0.53; P = .002). It was also significantly and positively correlated with the MMSE score ( r = 41; P = .02). Regression models showed that only the perception of being recognized, and not MMSE, significantly predicted lower caregiver objective burden scores. Furthermore, the use of a home care assistance service significantly predicted higher caregiver physical functioning. The perception of being recognized by an AD relative significantly predicted the caregiver's objective burden associated with a shortage of time. The use of a home care assistance service also resulted in a promotion in the caregiver's social functioning. Further studies are needed to confirm these results. PMID- 29580074 TI - Early Palliative Care for Patients With Brain Metastases Decreases Inpatient Admissions and Need for Imaging Studies. AB - BACKGROUND: Early encounters with palliative care (PC) can influence health-care utilization, clinical outcome, and cost. AIM: To study the effect of timing of PC encounters on brain metastasis patients at an academic medical center. SETTING/PARTICIPANTS: All patients diagnosed with brain metastases from January 2013 to August 2015 at a single institution with inpatient and/or outpatient PC records available for review (N = 145). DESIGN: Early PC was defined as having a PC encounter within 8 weeks of diagnosis with brain metastases; late PC was defined as having PC after 8 weeks of diagnosis. Propensity score matched cohorts of early (n = 46) and late (n = 46) PC patients were compared to control for differences in age, gender, and Karnofsky Performance Status (KPS) at diagnosis. Details of the palliative encounter, patient outcomes, and health-care utilization were collected. RESULTS: Early PC versus late PC patients had no differences in baseline KPS, age, or gender. Early PC patients had significantly fewer number of inpatient visits per patient (1.5 vs 2.9; P = .004), emergency department visits (1.2 vs 2.1; P = .006), positron emission tomography/computed tomography studies (1.2 vs 2.7, P = .005), magnetic resonance imaging scans (5.8 vs 8.1; P = .03), and radiosurgery procedures (0.6 vs 1.3; P < .001). There were no differences in overall survival (median 8.2 vs 11.2 months; P = .2). Following inpatient admissions, early PC patients were more likely to be discharged home (59% vs 35%; P = .04). CONCLUSIONS: Timely PC consultations are advisable in this patient population and can reduce health-care utilization. PMID- 29580075 TI - The Determinants of Palliative Care Use in Patients With Colorectal Cancer: A National Study. AB - BACKGROUND: Palliative care is associated with improved survival and quality of life, but its use among patients with colorectal cancer varies nationwide and the determinants of those variations are not clear. OBJECTIVE: To determine the factors associated with palliative care use among patients who died of colorectal cancer. METHODS: Deceased patients treated for colorectal cancer (2004-2013) were identified within the National Cancer Database. Multivariable logistic regression was used to evaluate patient and institutional characteristics associated with palliative care use. Patients were classified based on their length of survival (<6 months, 6-24 months, and 24+ months) to provide timing context. RESULTS: A total of 287 923 patients were analyzed. Overall, 4.3% of the patients received palliative care. Patients who received palliative care were more likely to be younger, recently diagnosed, treated at academic hospitals, and have stage IV disease. Patients living in Mountain and Pacific regions had higher odds of palliative care receipt than those in the East Coast. Patients without insurance had higher odds of palliative care if they survived <24 months. Insurance coverage through Medicaid was associated with increased palliative care use among patients who survived 6 to 24 months. Patients who survived <6 months and lived >9 miles from the institution received more palliative care. CONCLUSION: Palliative care use among patients with colorectal cancer is associated with a younger age, a more recent year of diagnosis, insurance status, academic hospitals, and living in Mountain and Pacific regions. PMID- 29580076 TI - Analyses of separate and concatenated cox1 and 18S rRNA gene sequences indicate that the bat piroplasm Babesia vesperuginis is phylogenetically close to Cytauxzoon felis and the 'prototheilerid' Babesia conradae. AB - Babesia vesperuginis is the only piroplasm known to infect bats. Unlike most members of the genus Babesia, it is probably transmitted by a soft tick species (i.e. Argas vespertilionis). Recently, two studies have been conducted to clarify the phylogenetic status of this species, and both agreed on placing it into a basal position among Babesia sensu stricto (s.s.). However, several important groups of piroplasms were not included in the already reported phylogenetic trees of B. vesperuginis isolates. Therefore, the aim of the present study was to amplify an approx. 950-bp fragment of the cytochrome c oxidase subunit 1 (cox1) gene of B. vesperuginis from A. vespertilionis specimens, and to compare its sequences with those from other piroplasmid groups in a broader phylogenetic context. Sequence comparisons focusing on either 18S rRNA or cox1 genes, as well as phylogenetic analyses involving separate and concatenated 18S rRNA and cox1 sequences indicate that B. vesperuginis is more closely related to the phylogenetic group of Theileriidae than to Babesia s.s. In particular, B. vesperuginis clustered closest to Cytauxzoon felis and the 'prototheilerid' B. conradae. The results of this study highlight that B. vesperuginis is a unique and taxonomically important species, which should be included in future studies aimed at resolving the comprehensive phylogeny of Piroplasmida. PMID- 29580078 TI - Characterisation of a multiresistant Pasteurella multocida strain isolated from cattle. AB - The emergence of simultaneous resistance to multiple classes of antibiotics presents an increasing threat. Plasmid-borne multiresistance and integrative conjugative elements have been reported in Pasteurella multocida. We report an alternative strategy for the development of multiresistance observed in a P. multocida strain (Pm238) isolated from calf pneumonia. We identified genes integrated into the chromosomal DNA without known integrative and conjugative elements. These genes conferred resistance to streptomycin (strA), tetracycline (tetB), chloramphenicol (catAIII), and sulphonamides (sulII). We also detected mutation in the quinolone-resistance-determining regions of parC. No plasmids could be isolated from strain Pm238. These results suggest that P. multocida can accumulate multiple resistance determinants on the chromosome as single genes. PMID- 29580077 TI - Caffeine strongly improves motility parameters of turkey spermatozoa with no effect on cell viability. AB - The purpose of this study was to evaluate the impact of caffeine on turkey spermatozoa during in vitro incubation. Experimental samples were prepared by diluting the raw semen with nine different concentrations of caffeine - from 0.078125 mg/mL to 10 mg/mL. The individual motility parameters were evaluated by the Computer Assisted Semen Analyser (CASA) system, and the viability of spermatozoa was evaluated using eosin-nigrosin staining. Selected parameters were recorded at six time periods: 0, 1, 2, 3, 4 and 5 h at 5 degrees C and 41 degrees C. A significantly higher motility and progressive motility of spermatozoa (P < 0.01 and P < 0.001, respectively) was detected in the samples containing caffeine ranging from 0.15625 to 7.5 mg/mL as compared to the control sample at 5 degrees C. At an incubation temperature of 41 degrees C the positive effect of caffeine on motility parameters was observed only at the beginning of incubation (at times 0 and 1). The tested caffeine concentrations showed no significant effect on the viability of turkey spermatozoa at any time period of incubation. A higher percentage of dead spermatozoa was observed for incubation at 41 degrees C (from 5.96% to 11.1%) in comparison to 5 degrees C (from 1.62% to 5.79%). The results suggest that caffeine can be used as a suitable component of turkey semen extenders and has the potential to improve fertility. PMID- 29580079 TI - Metagenomic analysis of bat guano samples revealed the presence of viruses potentially carried by insects, among others by Apis mellifera in Hungary. AB - The predominance of dietary viruses in bat guano samples had been described recently, suggesting a new opportunity to survey the prevalence and to detect new viruses of arthropods or even plant-infecting viruses circulating locally in the ecosystem. Here we describe the diversity of viruses belonging to the order Picornavirales in Hungarian insectivorous bat guano samples. The metagenomic analysis conducted on our samples has revealed the significant predominance of aphid lethal paralysis virus (ALPV) and Big Sioux River virus (BSRV) in Hungary for the first time. Phylogenetic analysis was used to clarify the relationship to previously identified ALPV strains infecting honey bees, showing that our strain possesses a close genetic relationship with the strains that have already been described as pathogenic to honey bees. Furthermore, studies have previously confirmed the ability of these viruses to replicate in adult honey bees; however, no signs related to these viruses have been revealed yet. With the identification of two recently described possibly honey bee infecting viruses for the first time in Hungary, our results might have importance for the health conditions of Hungarian honey bee colonies in the future. PMID- 29580080 TI - Coronavirus infection retards the development of the cortico-medullary capillary network in the bursa of Fabricius of chicken. AB - Coronavirus infection delays the development of the cortico-medullary (CM) capillary network which results in retarded development of bursal follicles. The smaller size of the medulla in the coronavirus-infected birds may lead to a lower number of B lymphocytes and bursal secretory dendritic cells, which negatively affects the reactivity and efficacy of the immune system. Contrary to the wild type infectious bronchitis virus (IBV) strain, infection induced by H120 vaccine virus exerts only a moderate influence on caveolin-1 expression of the CM capillary web and on follicular development compared to the untreated controls. PMID- 29580081 TI - Pulmonary hypertensive response of broiler chickens to arginine and guanidinoacetic acid under high-altitude hypoxia. AB - This study assessed the preventive effects of arginine (ARG) and guanidinoacetic acid (GAA) on the incidence of pulmonary hypertension syndrome (PHS) in broiler chickens. Four isoenergetic and isonitrogenous diets were prepared, including: (i) the control, (ii) the control supplemented with 1 g/kg ARG, (iii) the control supplemented with 1 g/kg GAA, and (iv) the control supplemented with 1.5 g/kg GAA. These diets were fed to broilers (Ross 308) from day 1 to 42 post-hatch. Criteria evaluated in the experiment were growth performance, carcass characteristics, serum and blood variables, lead-II electrocardiogram, and ET-1 and iNOS gene expression in heart and lungs. Mortality from PHS was recorded daily. The results showed that ARG and GAA supplements improved the feed conversion ratio (FCR) compared to the control (P < 0.05). Supplementation of ARG and GAA significantly (P < 0.05) increased serum nitric oxide (NO) concentration. ARG and GAA supplementation significantly reduced the haematocrit value and the heterophil to lymphocyte ratio in the blood. A significant (P < 0.05) decline in S-wave amplitude of the lead-II electrocardiogram, right to total ventricular weight ratio (RV:TV) and ascites mortality was observed by supplementing ARG or 1.5 g/kg GAA. Addition of ARG and GAA supplements did not significantly change ET 1 and iNOS gene expression in the heart and lung relative to the control. In conclusion, GAA supplementation at 1.5 g/kg had a potential to improve growth performance and could prevent PHS. PMID- 29580082 TI - Association of amniotic uric acid, glucose, lactate and creatinine concentrations and lactate/creatinine ratio with newborn survival in small-sized dogs - preliminary results. AB - In order to define the normal composition of canine amniotic fluid and to detect differences between surviving and non-surviving newborn puppies, the present study determined the uric acid, glucose, lactate and creatinine concentrations and the lactate to creatinine ratio in amniotic fluids collected during elective Caesarean section from small-sized purebred bitches. The possible relationship between newborn survival and the studied parameters, as well as the effects of maternal parity, fetal gender and Apgar score were assessed. The study enrolled 27 small-sized purebred bitches submitted to elective Caesarean section at term. After opening the fetal membranes, amniotic fluid samples were collected aseptically from the amniotic sac of each fetus. The data obtained from 74 amniotic fluid samples collected from 27 bitches showed that amniotic glucose concentration was lower (P < 0.05) in non-surviving than in surviving puppies. Within the normal, surviving puppies, amniotic glucose concentration was higher (P < 0.05) in male than in female newborns, and the lactate/creatinine ratio was significantly higher in multiparous than in primiparous bitches (P < 0.05). These preliminary results demonstrate the relevance of amniotic glucose, but not of uric acid, lactate, creatinine and the lactate to creatinine ratio for detecting puppies at risk of death immediately after birth. PMID- 29580083 TI - Rapid in-house detection method of Campylobacter spp. from food by redox potential monitoring combined with real-time PCR. AB - The rapid detection of Campylobacter spp. is of utmost importance for the reduction of infections in humans by contaminated food products. The standard culturing method (ISO 10272-1:2006) involves a high time and labour demand. In this paper, we present a method that reduces the detection time of Campylobacter spp. to or below one third as compared to the ISO method, at a reduced cost per test. We used redox potential change of enrichment cultures (Bolton broth with Bolton selective supplement) for reliably selecting Campylobacter-contaminated raw milk and broiler meat samples. Identification of Campylobacter spp. in the contaminated samples was done by real-time PCR method. Culturing time to conclusive redox monitoring varied between 6 and 24 h for positive samples, depending on the contamination rate, in contrast to 136 h with the standard culturing process. However, now the Campylobacter-negative majority of food samples will not need to be tested by real-time PCR because redox potential monitoring can identify them in the selective enrichment phase. This method could be potentially used as a faster alternative to the current standard ISO 10272 1:2006, for nonregulatory monitoring purposes. PMID- 29580084 TI - Effect of methionine deficiency on oxidative stress and apoptosis in the small intestine of broilers. AB - The aim of this study was to investigate the effects of methionine (Met) deficiency on antioxidant functions (in the duodenal, jejunal and ileal mucosa) and apoptosis in the duodenum, jejunum and ileum of broiler chickens. A total of 120 one-day-old Cobb broilers were divided into two groups and fed a Metdeficient diet and a control diet, respectively, for six weeks. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), the ability to inhibit hydroxyl radicals, and glutathione (GSH) content were significantly decreased in the Met-deficient group compared to the control. In contrast, malondialdehyde (MDA) content was significantly higher in the Met deficient group. As measured by terminal deoxynucleotidyl transferase 2' deoxyuridine 5'- triphosphate dUTP nick end-labelling (TUNEL) and flow cytometry (FCM), the percentages of apoptotic cells were significantly increased. In conclusion, dietary Met deficiency can cause oxidative stress and then induce increased apoptosis in the intestine. Oxidative stress contributes to intestinal apoptosis. This results in the impairment of local intestinal mucosal immunity due to oxidative stress and apoptosis in the small intestine. The results of this study provide new experimental evidence for understanding the negative effects of Met deficiency on mucosal immunity or the functions of other immune tissues. PMID- 29580085 TI - Monitoring minimal residual disease in canine lymphomas treated with modified L COP or L-CHOP protocols. AB - Heteroduplex polymerase chain reaction for antigen receptor rearrangements (hPARR) was developed to monitor minimal residual disease (MRD) in canine B- and T-cell lymphomas treated with the modified L-COP or L-CHOP protocol. Thirty-five dogs were recruited in this study and their neoplastic lineages were determined by immunophenotyping with Pax5 and CD3. Peripheral blood leukocytes were collected prior to and during chemotherapy in weeks 4, 9 and 13 to detect MRD by hPARR. Twenty-eight dogs (80%) had B-cell lymphoma while seven dogs (20%) had T cell lymphoma. A monoclonal band was detected in 11 cases that showed complete or partial remission before tumour relapse and no response to the current treatment without statistical difference in clinical outcomes; however, the treatment response had an association with the MRD result (P < 0.05). Modified L-CHOP prolonged median progression-free survival as compared to modified L-COP (215 days vs. 93 days; P < 0.05). Substage b had shorter progression-free survival than substage a (90 days vs. 215 days; P < 0.05). Clinical stage III affected median overall survival time when compared to clinical stages IV and V (432, 173 and 118 days, respectively; P < 0.05). hPARR could be used for screening refractory lymphoma together with lymph node measurement in routine clinical cases. PMID- 29580086 TI - Short-term effects of T-2 toxin or deoxynivalenol on glutathione status and expression of its regulatory genes in chicken. AB - Short-term (48-hour) effects of 3.74/1.26 mg kg-1 T-2/HT-2 toxin or 16.12 mg kg-1 DON in feed were investigated in the liver of three-week-old cockerels (body weight: 749.60 +/- 90.98 g). Markers of lipid peroxidation showed no significant changes. At hour 24, glutathione content in the T-2/HT-2 toxin group was significantly higher than in the control. Glutathione peroxidase activity was significantly higher than the control at hour 24 in the T-2/H-2 toxin group and at hour 48 in the DON group. In the DON group, expression of the glutathione peroxidase 4 gene (GPX4) was significantly lower than in the control at hours 12 and 14, and higher at hour 48. Expression of the glutathione reductase gene (GSR) was significantly lower than in the control at hour 12 in the T-2/HT-2 toxin group, and at hours 12, 24 and 48 in the DON group. However, at hour 36 higher GSR expression was measured in the DON group. Due to the effect of both trichothecenes, expression of the glutathione synthetase gene (GSS) was significantly lower than in the control at hours 24 and 48. In conclusion, T-2/HT 2 toxin and DON had a moderate short-term effect on free radical formation. T 2/HT-2 toxin induced more pronounced activation of the glutathione redox system than did DON. PMID- 29580088 TI - Effect of fulvic and humic acids on copper and zinc homeostasis in rats. AB - The objective of this study was to investigate the effects of fulvic acid (FA) and humic acid (HA), the two main compounds of humic substances (HSs), on copper (Cu) and zinc (Zn) homeostasis. Seventy-two male Wistar rats were randomly divided into nine experimental groups. The control diet (AIN-93G formula) and the diets supplemented with 0.1%, 0.2%, 0.4% and 0.8% FA or HA were fed for 26 days. Cu and Zn concentrations of the large intestinal content (LIC), liver, kidney, femur and hair were determined. FA and HA did not influence significantly the Cu or Zn contents of the experimental diets, the rats' feed intake, weight gain and the feed to gain ratio. Both FA and HA decreased the Cu concentrations of the LIC significantly and in a dose-related manner; however the absorption-stimulating effect of HA was more pronounced. FA increased the Cu content of the liver, but neither FA nor HA had a dose-dependent effect on it. FA or HA supplementations had no significant effect on the Cu concentration of the kidney. At the concentrations used, dietary FA or HA supplementations are not promising growth promoters. FA influences the Cu homeostasis unlike HA, because FA not only stimulates Cu absorption, but the extra quantity of absorbed Cu is retained in the organism. The stimulatory effect of HA on Zn absorption may not be manifested in Cu and Zn homeostasis, because of the tight connection of these microelements to FA and HA, which prevents the transmission of Zn from the ZnHA complex to the organs. As regards the effect of FA and HA on Cu and Zn homeostasis, both FA and HA stimulated the absorption of these microelements, but only FA increased the retention of Cu (in the liver) and Zn (in the kidney). PMID- 29580089 TI - Detection and molecular characterisation of Ehrlichia canis in naturally infected dogs in South West Nigeria. AB - Canine ehrlichiosis is an important tick-borne rickettsial disease mainly caused by Ehrlichia canis. This study aimed to detect and characterise E. canis in dogs in Abeokuta, Nigeria by microscopy and nested PCR. Blood samples were collected from 205 dogs, thin smears were made, field-stained, and DNA was extracted from the blood samples. A partial region of the 16S rRNA gene was amplified by polymerase chain reaction (PCR) and sequenced unidirectionally. Ehrlichial morulae were detected in three dogs (1.5%). The PCR test revealed that 47 dogs (22.9%) were positive for E. canis. The lengths of the sequences obtained range from 374 bp to 376 bp with an average G-C content of 37% and 98-99% homology with the reference sequences in GenBank. The aligned autochthonous sequences were less polymorphic. The phylogenetic analysis separated sequences reported previously in Nigeria from the autochthonous sequences. The present work shows that the strain of E. canis detected in the study area is genetically different from those reported in the northern part of Nigeria and more closely related to sequences from Brazil and India. PMID- 29580090 TI - Helminths of European smelt Osmerus eperlanus (Linnaeus, 1758) in Lake Hancza and the Vistula Lagoon, with special regard to their zoonotic threats. AB - Reports published in recent years on the increased risk in the Baltic Sea of fish infection with larvae of nematodes potentially pathogenic to humans have prompted a study of European smelt Osmerus eperlanus with respect to the presence of these parasites in the Vistula Lagoon. Additionally, samples of this fish from Lake Hancza were comparatively considered. The body cavity, the surface of internal organs, the alimentary tract and the swimbladder of fish from two environmentally different water bodies were taken into account in the analysis. Only the tapeworm Proteocephalus longicollis was found in the alimentary tract of the fish from Lake Hancza. Depending on the period of study, the prevalence ranged from 60% to 100%, and the mean intensity from 11.5 to 42.0. The helminth fauna of smelt from the Vistula Lagoon was more diverse: Cystidicola farionis occurred with a prevalence from 25.9 to 75.0% and a mean intensity of infection from 2.7 to 66.0%, Proteocephalus longicollis and cystacanths of Corynosoma with a prevalence ranging in different years from 12.0 to 44.0% and from 14.8 to 50.0%, respectively. Zoonotic parasites, such as nematode larvae of the Anisakidae family (Contracaecum sp., Anisakis simplex), occurred in the intestine with a prevalence of 31%, 72% and 22% in consecutive years of the study. PMID- 29580091 TI - Maternal-Neonatal Pheromone/Interomone Added to Cat Litter Improves Litter Box Use and Reduces Aggression in Pair-Housed Cats. AB - Introducing a new cat into a household with one or more resident cats can be a significant source of stress for the cats involved. These studies sought to determine if rabbit maternal-neonatal pheromone (2-methyl-2-butenal [2M2B]) in litter impacted cat social behaviors and litter box use. Study 1 determined that cats preferred to eliminate in litter containing 2M2B; other semiochemicals tested did not change litter box use. Cats prone to aggression were identified in an intermediate pilot study, and eight pairs of these cats were selected for Study 2. In Study 2, cat pairs were provided litter containing either vehicle or 2M2B for 24 hours. Cats experiencing control litter displayed more aggression during the first 6 hours (p < .01) and spent more time using the litter box 12 hours and 18 hours after pairing compared with cats experiencing litter with 2M2B (p = .02). These results suggest 2M2B-infused cat litter may act as an interomone in cats housed domestically to prevent initial occurrences of aggression and may improve cat welfare in multicat households. PMID- 29580092 TI - Ventral tegmental area inactivation alters hormonal, metabolic, and locomotor responses to inescapable stress. AB - CONTEXT: The involvement of unilateral and bilateral inhibition of the ventral tegmental area (VTA) in response to stress is not well understood. OBJECTIVE: In the present study, the effect of unilateral and bilateral inhibition of the VTA on hormonal, metabolic, and locomotor responses to stress was assessed. MATERIAL AND METHODS: Male rats seven days after cannulation into the VTA received electro foot-shock stress for seven consecutive days. Twenty minutes before induction of stress, 2% lidocaine hydrochloride or sterile saline (control) was injected either uni- or bi-laterally into the VTA. RESULTS: Results showed that stress significantly increased serum corticosterone level, adrenal gland weight and anorexia, reduced weight gain, food-intake, and locomotor activity. However, bilateral inactivation of VTA prevented stress-induced these parameters changes. CONCLUSION: The present study demonstrated that the bilateral VTA blockade effectively relieves the symptoms of stress, while the unilateral VTA blockade does not significantly improve the changes caused by stress. PMID- 29580093 TI - What is the relationship between self-reported aberrant driving behaviors, mindfulness, and self-reported crashes and infringements? AB - OBJECTIVES: This study investigated the relationship between self-reported aberrant driving behaviors, mindfulness, and self-reported crashes and infringements. METHODS: Three hundred and eighteen participants (M = 46.0 years, SD = 13.7 years; female: 81.8%) completed an online survey that assessed aberrant driving behaviors, mindfulness (including regular mindfulness meditation [MM]), and self-reported crashes and infringements during the past 2 years. Structural equation modeling (SEM) was used to examine the relationship between self reported aberrant driving behaviors and mindfulness simultaneously, as well as with participants' age and estimated kilometers driven over the past year. RESULTS: The results of the SEM showed that mindfulness was negatively related to each self-reported aberrant driving behavior, with the strongest relationships being between mindfulness and driving-related lapses (-0.58) and errors (-0.46). Participants who practice MM had significantly fewer crashes in the past 2 years and reported significantly fewer driving-related violations and lapses compared to participants who did not practice MM (crashes: 9.3% vs. 18.8%, P < .05; violations: M = 6.66 [SD = 3.44] vs. M = 7.68 [SD = 4.53], P < .05; errors: M = 5.17 [SD = 3.44] vs. M = 6.19 [SD = 4.12], P < .05). CONCLUSIONS: More research is needed to understand whether MM results in more mindful and attentive drivers or whether individuals who practice MM may have other traits or behaviors that are linked to improved safety. PMID- 29580094 TI - Outcomes of Noninvasively Treated Idiopathic Toe Walkers. AB - : Idiopathic toe walking (ITW) causes a common problem in pediatric orthopaedics. In the literature, numerous treatment options have been reported, but consensus about the management of ITW is still missing. The aim of the current study was to evaluate conservative treatment with pyramidal insoles. A total of 193 patients underwent conservative treatment between January 2010 and June 2013. Mean age at the beginning of the treatment was 7.75 +/- 0.23 years (range 2.0-17.0 years). For all patients, demographic data, comorbid diseases, passive range of motion (ROM), persistent toe walking, and performed operations were retrospectively evaluated. Following operative treatment was defined failure. Eight (4.15%) patients underwent Achilles tendon lengthening operation after mean therapy time of 2.72 years (range 0.1-7.0 years), 174 cases were treated successfully (90.16%). In 50 cases, toe walking suspended completely after mean therapy time of 2.83 years. In cases of failure, patients were older at diagnosis and at the beginning of the treatment. Mean passive ROM increased over the time. In cases of failure, ROM decreased from the first to the second examination. Conservative treatment of ITW using pyramidal insoles can be effective. Ankle dorsiflexion significantly improved in the patients who were successfully treated. Therapy should start early. A decrease of ROM under therapy should lead to critical revisal of individual therapy. LEVELS OF EVIDENCE: Therapeutic, level IV: Case series. PMID- 29580095 TI - Minimal Invasive Fixation Can Decrease Infection Rates in Diabetic and Obese Patients With Severe Ankle Fracture and Syndesmotic Injury. AB - BACKGROUND: Ankle fractures involving syndesmosis disruption cause severely unstable joint conditions. Traditional invasive operations put certain patient groups at an increased risk of infection. There is limited literature discussing the outcomes of minimally invasive fixation of severe ankle fractures including syndesmotic injury, as clinicians may be tempted to treat these difficult cases with open reduction internal fixation (ORIF). METHODS: A retrospective case control study was conducted on patients treated at a level one trauma center. Patients were divided into 2 groups based on presence of diabetes and/or obesity (body mass index >=30.0 kg/m2). Those with either comorbidity were defined as high infection risk patients and placed in a comorbidity group. Patients were further divided into subgroups based on the operation's invasiveness; either traditional ORIF or percutaneous cannulated screw fixation. RESULTS: Comorbid patients (N = 67) were more likely to sustain Weber C fractures compared to noncomorbid patients (N = 43) (59.70% to 37.21%, P = .019). Additionally, patients receiving minimally invasive fixation procedures experienced fewer infections than those receiving ORIF (0 vs 11 incidences, P = .01), without effect on union rates, fracture reduction, pain, need for revision surgery, or time to full weightbearing. CONCLUSIONS: Diabetic and obese patients are at an increased risk of experiencing severe ankle fractures. The use of minimally invasive fixation methods can reduce the risk of postoperative infection without sacrificing other surgical outcomes, even with fractures involving syndesmotic injury. LEVELS OF EVIDENCE: Therapeutic, Level III: Retrospective comparative study. PMID- 29580096 TI - Comparison of intensive versus conventional insulin therapy in traumatic brain injury: a meta-analysis of randomized controlled trials. AB - OBJECTIVE: To compare intensive insulin therapy (IIT) and conventional insulin therapy (CIT) on clinical outcomes of patients with traumatic brain injury (TBI). METHODS: MEDLINE, EMBASE, Google Scholar, ISI Web of Science, and Cochrane Library were systematically searched for randomized controlled trials (RCTs) comparing IIT to CIT in patients with TBI. Study-level characteristics, intensive care unit (ICU) events, and long-term functional outcomes were extracted from the articles. Meta-analysis was performed with random-effect models. RESULTS: Seven RCTs comprising 1070 patients were included. Although IIT was associated with better neurologic outcome (GOS > 3) (RR=0.87, 95% CI=0.78-0.97; P=0.01; I2=0%), sensitivity analysis revealed that one study influenced this overall estimate (RR=0.90, 95% CI=0.80-1.01, P=0.07; I2=0%). IIT was strongly associated with higher risk of hypoglycaemia (RR=5.79, 95% CI=3.27-10.26, P<0.01; I2=38%). IIT and CIT did not differ in terms of early or late mortality (RR=0.96, 95% CI=0.79 1.17, P=0.7; I2=0%), infection rate (RR=0.82, 95% CI=0.59-1.14, P=0.23; I2=68%), or ICU length of stay (SMD= -0.14, 95% CI=-0.35 to 0.07, P=0.18; I2=45%0.) Conclusions: IIT did not improve long-term neurologic outcome, mortality, or infection rate and was associated with increased risk of hypoglycaemia. Additional well-designed RCTs with defined TBI subgroups should be performed to generate more powerful conclusions. PMID- 29580097 TI - The Influence of Materialism on Purebred Dogs' Welfare Among Two Different Generations in Colombia (South America). AB - Some consumers in Colombia show a clear preference for purebred dogs. At the same time, there are many abandoned dogs on the streets and in shelters in this country. Previous research has revealed that appearances of the breeds influence the caregivers' (owners') choice. A choice based on appearances has been connected with materialism in the psychology and consumer behavior literature. Buying purebred dogs based on materialistic standards could affect the welfare of these nonhuman animals. With the use of quantitative research and the methodology of structural equation modeling, this research demonstrated that more materialistic consumers in Colombia have purebred dogs who, in the owners' opinions, show more behavioral problems. Furthermore, the results showed that materialism influenced the owners' intentions to abandon their companion animals when they perceived these problems. Finally, this research examined the moderating effect of generational segmentation regarding these relationships. It was observed that the intention to abandon the dogs was greater among members of Generation X than among members of Generation Y.

PMID- 29580100 TI - Assessment of AAV Vector Tropisms for Mouse and Human Pluripotent Stem Cell Derived RPE and Photoreceptor Cells. AB - Adeno-associated viral vectors are showing great promise as gene therapy vectors for a wide range of retinal disorders. To date, evaluation of therapeutic approaches has depended almost exclusively on the use of animal models. With recent advances in human stem cell technology, stem cell-derived retina now offers the possibility to assess efficacy in human organoids in vitro. Here we test six adeno-associated virus (AAV) serotypes [AAV2/2, AAV2/9, AAV2/8, AAV2/8T(Y733F), AAV2/5, and ShH10] to determine their efficiency in transducing mouse and human pluripotent stem cell-derived retinal pigment epithelium (RPE) and photoreceptor cells in vitro. All the serotypes tested were capable of transducing RPE and photoreceptor cells in vitro. AAV ShH10 and AAV2/5 are the most efficient vectors at transducing both mouse and human RPE, while AAV2/8 and ShH10 achieved similarly robust transduction of human embryonic stem cell-derived cone photoreceptors. Furthermore, we show that human embryonic stem cell-derived photoreceptors can be used to establish promoter specificity in human cells in vitro. The results of this study will aid capsid selection and vector design for preclinical evaluation of gene therapy approaches, such as gene editing, that require the use of human cells and tissues. PMID- 29580101 TI - Application of energy derivative method to determine the structural components' contribution to deceleration in crashes. AB - OBJECTIVE: For occupant protection, it is important to understand how a car's deceleration time history in crashes can be designed using efficient of energy absorption by a car body's structure. In a previous paper, the authors proposed an energy derivative method to determine each structural component's contribution to the longitudinal deceleration of a car passenger compartment in crashes. In this study, this method was extended to 2 dimensions in order to analyze various crash test conditions. The contribution of each structure estimated from the energy derivative method was compared to that from a conventional finite element (FE) analysis method using cross-sectional forces. METHOD: A 2-dimensional energy derivative method was established. A simple FE model with a structural column connected to a rigid body was used to confirm the validity of this method and to compare with the result of cross-sectional forces determined using conventional analysis. Applying this method to a full-width frontal impact simulation of a car FE model, the contribution and the cross-sectional forces of the front rails were compared. In addition, this method was applied to a pedestrian headform FE simulation in order to determine the influence of the structural and inertia forces of the hood structures on the deceleration of the headform undergoing planar motion. RESULT: In an oblique impact of the simple column and rigid body model, the sum of the contributions of each part agrees with the rigid body deceleration, which indicates the validity of the 2-dimensional energy derivative method. Using the energy derivative method, it was observed that each part of the column contributes to the deceleration of the rigid body by collapsing in the sequence from front to rear, whereas the cross-sectional force at the rear of the column cannot detect the continuous collapse. In the full-width impact of a car, the contributions of the front rails estimated in the energy derivative method was smaller than that using the cross-sectional forces at the rear end of the front rails due to the deformation of the passenger compartment. For a pedestrian headform impact, the inertial and structural forces of the hood contributed to peaks of the headform deceleration in the initial and latter phases, respectively. CONCLUSIONS: Using the 2-dimensional energy derivative method, it is possible to analyze an oblique impact or a pedestrian headform impact with large rotations. This method has advantages compared to the conventional approach using cross-sectional forces because the contribution of each component to system deceleration can be determined. PMID- 29580102 TI - Ocular surface changes in recurrent pterygium cases post-operatively treated with 5-fluorouracil subconjunctival injections. AB - INTRODUCTION: To investigate the ocular surface changes occurring in eyes with recurrent pterygium post-operatively treated with 5-fluorouracil intralesional injections. METHODS: Retrospective observational study of recurrent pterygium cases treated with weekly intralesional injections of 0.1 mL (5 mg) of 5 fluorouracil (10 injections). Impression cytology samples taken from the lesion, the healthy conjunctivae (inferior, superior, and contralateral to injury), and the cornea before and after treatment were analyzed. Clinical ocular characteristics (including Schirmer's test and break-up time) were evaluated during treatment. RESULTS: A total of 15 eyes were treated, with the mean follow up of 27 +/- 8.7 months (mean +/- standard deviation). Prior to treatment initiation, the ocular surface citology over the pterygium was found to be abnormal. No epithelial cells (27%) and a lower goblet cell density (73%) compared to the healthy conjunctivae (p < 0.01) were found. Squamous metaplasia was observed to some degree in the cornea (100%), pterygium (81%) and healthy conjunctivae (73%). Following treatment, pterygium composition had changed: epithelial cell number (100%) and goblet cell density (47%) had increased (p < 0.05). Goblet cell density was also increased in healthy conjunctivae (67%; p < 0.05). The degree of squamous metaplasia decreased in the cornea (67%), pterygium (45%), and healthy conjunctivae (60%; p < 0.05). No adverse effects were reported, recurrence progression was arrested, and conjunctival redness and dry eye severity level were decreased in all cases (p < 0.01). DISCUSSION: The cytology of ocular surface in recurrent pterygium is abnormal. After weekly intralesional 5-fluorouracil injections, it tends to normalize. The 5 fluorouracil compound is a safe and effective treatment to prevent pterygium recurrence. PMID- 29580103 TI - Distribution of keratometry and its determinants in a general population of 6- to 12-year-old children. AB - PURPOSE: To determine the distribution of keratometry and its determinants in Iranian school children. METHODS: The present cross-sectional study was conducted in 2015 in Shahroud in the north of Iran. The entire rural population of elementary school children was invited to the study. In urban areas, cluster sampling was conducted. Pentacam HR (Oculus Inc., Lynnwood, WA) was used to measure the flat meridian, the steep meridian, and the mean keratometry. Linear regression was used to determine the associated variables with mean keratometry. RESULTS: Of 5620 participated in the study, 5559 children were analyzed after applying the exclusion criteria. Mean keratometry was 43.56 +/- 1.96 diopters (D) (95% confidence interval = 43.48-43.64) in the total sample, 43.18 +/- 2.23 D (95% confidence interval = 43.09-43.26) in boys, and 44.01 +/- 1.46 D (95% confidence interval = 43.95-44.07) in girls (p < 0.001). The highest and lowest mean keratometry was 43.28 +/- 1.66 D (95% confidence interval = 43.00-43.55) and 42.89 +/-2.70 D (95% confidence interval = 42.68-43.11) in 6-year-old and 10-year old children, respectively (p = 0.031). The results of multiple linear regression showed that mean keratometry in girls was 0.82 D higher than in boys (p < 0.001), and in groups older than 9 years, it was significantly decreased. Mean keratometry in myopic children was 0.62 D higher than emmetropic children (p < 0.001). CONCLUSION: This study provided valuable findings from the status of keratometry in Iranian children. In line with other studies, corneal power was higher in girls than in boys, and the cornea becomes flatter with age in children. PMID- 29580105 TI - Herbal Remedies: A Boon for Diabetic Neuropathy. AB - Diabetic neuropathy is a chronic complication of diabetes mellitus affecting about 50% of patients. Its symptoms include decreased motility and severe pain in peripheral parts. The pathogenesis involved is an abnormality in blood vessels that supply the peripheral nerves, metabolic disorders such as myo-inositol depletion, and increased nonenzymatic glycation. Moreover, oxidative stress in neurons results in activation of multiple biochemical pathways, which results in the generation of free radicals. Apart from available marketed formulations, extensive research is being carried out on herbal-based natural products to control hyperglycemia and its associated complications. This review is focused to provide a summary on diabetic neuropathy covering its etiology, types, and existing work on herbal-based therapies, which include pure compounds isolated from plant materials, plant extracts, and Ayurvedic preparations. PMID- 29580104 TI - Soluble glycoprotein 130 is inversely related to severity of coronary atherosclerosis. AB - PURPOSE: Recent studies indicate that the effects of interleukin 6 (IL-6) realized via soluble IL-6 receptor (sIL-6R) facilitate the development of various pathological processes. Soluble gp130 (sgp130) is a naturally occurring inhibitor of signal transduction via this pathway. In this study, we assessed the relationship between circulating levels of IL-6, sIL-6R and sgp130 and severity of coronary atherosclerosis in patients with stable coronary artery disease (CAD). METHODS: Plasma levels of IL-6, sIL-6R and sgp130 were measured in patients with atherosclerotic coronary lesions (n = 128, group 1) and with intact coronary arteries (n = 48, group 2). The severity of coronary atherosclerosis was evaluated by the number of affected arteries and by Gensini Score index. RESULTS: Circulating IL-6 levels in group 1 were significantly higher than those in group 2. The levels of sIL-6R did not differ considerably in both the groups. The levels of sgp130 in group 1 were significantly lower than in group 2. A negative correlation has been revealed between sgp130 levels and the number of affected coronary arteries and Gensini Score index. CONCLUSIONS: Serum concentration of sgp130 in patients with stable CAD is inversely related to severity of coronary damage. Low sgp130 level may serve as an additional indicator of coronary atherosclerosis severity. PMID- 29580106 TI - Flagellin as a vaccine adjuvant. AB - INTRODUCTION: Bacterial flagellin, as a pathogen-associated molecular pattern (PAMP), can activate both innate and adaptive immunity. Its unique structural characteristics endow an effective and flexible adjuvant activity, which allow the design of different types of vaccine strategies to prevent various diseases. This review will discuss recent progress in the mechanism of action of flagellin and its prospects for use as a vaccine adjuvant. Areas covered: Herein we summarize various types of information related to flagellin adjuvants from PubMed, including structures, signaling pathways, natural immunity, and extensive applications in vaccines, and it discusses the immunogenicity, safety, and efficacy of flagellin-adjuvanted vaccines in clinical trials. Expert commentary: It is widely accepted that as an adjuvant, flagellin can induce an enhanced antigen-specific immune response. Flagellin adjuvants will allow more effective flagellin-based vaccines to enter clinical trials. Furthermore, vaccine formulations containing PAMPs are crucial to exert the maximum potential of vaccine antigens. Therefore, combinations of flagellin-adjuvanted vaccines with other adjuvants that act in a synergistic manner, particularly TLR ligands, represent a promising method for tailoring targeted vaccines to meet specific requirements.

PMID- 29580108 TI - The feasibility of assessing speech and non-speech function of the speech apparatus in adults with cerebral palsy. AB - This short note reports on observations concerning the feasibility of a set of speech and non-speech assessment tasks in an investigation of dysarthria in 21 adults (15 males/6 females; median 23 years) with cerebral palsy and concomitant cognitive impairment. The participants were assessed with nine tasks representing standard components of clinical dysarthria assessment (i.e. six speech and three non-speech tasks). The tasks were evaluated for their feasibility on the basis of common clinical criteria. Our results indicated that, overall, speech tasks were more feasible than non-speech tasks. Several participants showed signs of dysexecutive behaviour on some of the non-speech tasks, but not on the speech tasks. The current note provides tentative clues regarding the impact of cognitive deficits on the feasibility of assessment tasks in the diagnosis of dysarthria. PMID- 29580109 TI - Total pathological complete response versus breast pathological complete response in clinical trials of reference and biosimilar trastuzumab in the neoadjuvant treatment of breast cancer. AB - INTRODUCTION: Trastuzumab is a key drug in the neoadjuvant treatment of breast cancers that overexpress the human epidermal growth factor receptor 2 (HER2). Pathological complete response (pCR) is commonly used as an endpoint in neoadjuvant clinical trials of trastuzumab as evidence suggests it may be a surrogate for long-term survival. Several biosimilar candidates of originator or 'reference' trastuzumab are in development and have used pCR as a primary endpoint to assess therapeutic equivalence between treatments. The exact definition of pCR has varied across studies. Areas covered: Here we look at the clinical relevance of pCR and compare rates of total pCR (defined as ypT0/is ypN0) and breast pCR (defined as ypT0/is) in clinical trials of reference and biosimilar trastuzumab. Expert commentary: In order to evaluate the efficacy of neoadjuvant systemic therapies in a uniform way, standardization of trial endpoints is necessary. Future studies in HER2-positive breast cancer should include full assessment of the breast and lymph node basin before and after neoadjuvant systemic therapy, and the use of total pCR as the primary outcome. PMID- 29580110 TI - Current and future molecular approaches in the diagnosis of cystic fibrosis. AB - INTRODUCTION: Cystic Fibrosis is among the first diseases to have general population genetic screening tests and one of the most common indications of prenatal and preimplantation genetic diagnosis for single gene disorders. During the past twenty years, thanks to the evolution of diagnostic techniques, our knowledge of CFTR genetics and pathophysiological mechanisms involved in cystic fibrosis has significantly improved. Areas covered: Sanger sequencing and quantitative methods greatly contributed to the identification of more than 2,000 sequence variations reported worldwide in the CFTR gene. We are now entering a new technological age with the generalization of high throughput approaches such as Next Generation Sequencing and Droplet Digital PCR technologies in diagnostics laboratories. These powerful technologies open up new perspectives for scanning the entire CFTR locus, exploring modifier factors that possibly influence the clinical evolution of patients, and for preimplantation and prenatal diagnosis. Expert commentary: Such breakthroughs would, however, require powerful bioinformatics tools and relevant functional tests of variants for analysis and interpretation of the resulting data. Ultimately, an optimal use of all those resources may improve patient care and therapeutic decision-making. PMID- 29580111 TI - The African American Eye Disease Study: Design and Methods. AB - PURPOSE: To describe the study design, operational and recruitment strategies, procedures, and baseline characteristics of the African American Eye Disease Study (AFEDS), a population-based assement of the prevalence of visual impairment, ocular disease, visual function, and health-related quality of life in African Americans. METHODS: This population-based, cross-sectional study included over 6000 African Americans 40 years and older residing in and around Inglewood, California. A detailed interview and eye examination was performed on each eligible participant. The interview included an assessment of demographic, behavioral, and ocular risk factors and health-related and vision-related quality of life. The eye examination included measurements of visual acuity, intraocular pressure, visual fields; fundus and optic disc photography; a detailed anterior and posterior segment examination; and measurements of blood pressure, glycosylated hemoglobin levels, and blood glucose levels. RESULTS: The AFEDS cohort includes more than 6000 participants that have completed a home questionnaire and a comprehensive eye examination. The majority of participants were female (63%), the average (+/- standard deviation) overall age was 60.9 (+/ 11.3). Participants are mostly working (40%) or retired (41%), non-smoking (57%), partial drinking (54%), and with at least some college education (38%). A trust development recruitment strategy was refined in order to overcome challenges in study participation. CONCLUSION: The AFEDS is the largest epidemiologic eye study among African Americans to date. The AFEDS cohort will provide information about the prevalence and risk factors of ocular disease in the largest ophthalmologic study population of African Americans in the United States. PMID- 29580112 TI - Invasive Mammary Carcinoma With Mixed Invasive Papillary and Glycogen Rich Clear Cell Features. AB - Invasive papillary carcinoma (IPC) and glycogen-rich clear cell carcinoma (GRCCC) are rare primary breast carcinomas. IPC typically have favorable prognosis, whereas the prognosis of GRCCC is less established. We report a unique case of high-grade invasive mammary carcinoma with mixed IPC and GRCCC features. We review the imaging and pathologic features and discuss prognosis of these unusual breast cancer subtypes. PMID- 29580113 TI - Platelet biomechanics, platelet bioenergetics, and applications to clinical practice and translational research. AB - The purpose of this review is to explore the relationship between platelet bioenergetics and biomechanics and how this relationship affects the clinical interpretation of platelet function devices. Recent experimental and technological advances highlight platelet bioenergetics and biomechanics as alternative avenues for collecting clinically relevant data. Platelet bioenergetics drive energy production for key biomechanical processes like adhesion, spreading, aggregation, and contraction. Platelet function devices like thromboelastography, thromboelastometry, and aggregometry measure these biomechanical processes. Platelet storage, stroke, sepsis, trauma, or the activity of antiplatelet drugs alters measures of platelet function. However, the specific mechanisms governing these alterations in platelet function and how they relate to platelet bioenergetics are still under investigation. PMID- 29580114 TI - Athletes and Supplements: Prevalence and Perspectives. AB - In elite sport, where opponents are evenly matched, small factors can determine the outcome of sporting contests. Not all athletes know the value of making wise nutrition choices, but anything that might give a competitive edge, including dietary supplements, can seem attractive. Between 40% and 100% of athletes typically use supplements, depending on the type of sport, level of competition, and the definition of supplements. However, unless the athlete has a nutrient deficiency, supplementation may not improve performance and may have a detrimental effect on both performance and health. Dietary supplements are classified as a subcategory of food, so manufacturers are not required to provide evidence of product safety and efficacy, nor obtain approval from regulatory bodies before marketing supplements. This creates the potential for health risks, and serious adverse effects have been reported from the use of some dietary supplements. Athletes who compete in sports under an anti-doping code must also realize that supplement use exposes them to a risk of ingesting banned substances or precursors of prohibited substances. Government systems of regulations do not include specific laboratory testing for banned substances according to the WADA list, so a separate regulatory framework to evaluate supplements for their risk of provoking a failed doping test is needed. In the high-performance culture typical of elite sport, athletes may use supplements regardless of possible risks. A discussion around medical, physiological, cultural, and ethical questions may be warranted to ensure that the athlete has the information needed to make an informed choice. PMID- 29580116 TI - Novel Surgical Techniques in Guided Bone Regeneration. PMID- 29580115 TI - Comparison of four methods to assess high-on platelet reactivity under P2Y12 receptor inhibitor. AB - P2Y12 receptor inhibitors are antiplatelet agents commonly prescribed in the treatment of coronary artery disease. Their efficacy can be limited by high on treatment platelet reactivity (HPR), which can be evaluated by different biological assays. Most commonly, HPR is evaluated by flow cytometric vasodilator stimulated phosphoprotein-phosphorylation (VASP-P) assay, which can be time consuming. To evaluate the potential interest of novel technologies, we compared four different assays. Ninety patients receiving P2Y12 inhibitors were included. Four technologies were evaluated: the current standard test measuring VASP-P by flow cytometry, the historical reference test based on light transmittance aggregation (LTA), and two relatively novel techniques: whole blood multiple electrode aggregometry (MEA) and platelet function analyzer (PFA), which are less time consuming. The three latter tests were compared with the VASP-P assay as a reference using receiver operating characteristics (ROC) analysis: LTA has an excellent comparability with the VASP test (ROC AUC > 0.9); the other two tests (multiplate and PFA) have only satisfactory comparability (ROC AUC around 0.7) and therefore may not replace the VASP "gold standard" test, if importance is attached to a quantitative assessment of the substitution parameter of VASP. Nevertheless, if a binary approach of the anti-aggregation result is sought, then one can conclude that the three tests are equivalent since Cohen's kappa coefficients are very close for the three tests (k = 0.548 for LTA; k = 0.554 for MEA; k = 0.570 for PFA/P2Y), and a similar proportion of patients are misclassified (15% for LTA, 14% for MEA, and 13.6% for PFA). Discriminant factor analysis using all the parameters provided by each test did not improve the diagnostic performance of MEA or PFA. In conclusion, only LTA shows a good comparability to the VASP assay using ROC curve analysis, probably because misclassified patients have results close to the cutoff values. All three tests have moderate agreement regarding the classification of patients as responders to P2Y12 inhibition. PMID- 29580117 TI - Evidence for panmixia despite barriers to gene flow in the hooked mussel, Ischadium recurvum (Mytilidae; Brachidontinae) along the North American coastline. AB - The discovery of phylogeographic patterns within broadly distributed marine species can be particularly challenging because absolute physical barriers to dispersal can be inconspicuous. Genetic boundaries often lie where ocean currents meet, forming sharp physical and ecological gradients, which may act as barriers to successful migrants. In eastern North America, coastal species often show phylogeographic differentiation associated with two recognized genetic barriers: the Gulf/Atlantic and the Virginia/Carolina discontinuities. We examined 185 specimens of the intertidal hooked mussel Ischadium recurvum collected from 15 locations along the eastern coastline of North America to examine phylogeographic, migration and historical demographic patterns associated climate change associated with Pleistocene glacial patterns. Hypothesis testing using Bayes factors in Migrate-n rejected the presence of phylogeographic breaks consistent with either maritime discontinuity and favoured a panmictic population model. The migration rate from the Gulf to the Atlantic was approximately three times higher than the migration from the Atlantic to the Gulf whereas the Carolina-Virginia migration rates were nearly equal. The summary statistics (Tajima's D, Fu's Fs) were significant and the demographic analyses (mismatch distributions, Bayesian skyline plot) were consistent with patterns of population expansion following glacial retreat during the Pleistocene epoch. PMID- 29580118 TI - Invasive Solid Papillary Carcinoma of the Nipple With Pagetoid Extension and Nodal Metastasis. AB - We report a case of invasive solid papillary carcinoma (SPC) of the nipple with Pagetoid extension to the skin and lymph node metastasis. SPC is an uncommon primary breast cancer accounting for less than 1% of all breast cancers. Only 2 cases occurring in the nipple have been reported. However, both cases were without Pagetoid extension or lymph node metastasis. The presently reported tumor consisted of irregularly shaped solid cell nests with delicate fibrovascular cores. The tumor cells had round nuclei with low-grade atypia and eosinophilic cytoplasm. Neuroendocrine differentiation was confirmed by immunohistochemical positivity for CD56, synaptophysin, and chromogranin A. Immunohistochemistry also confirmed the absence of myoepithelial cells around the tumor cell nests. Therefore, a diagnosis of invasive SPC was made. Additionally, tumor cell deposits in the intramammary and axillary lymph nodes were identified, and these deposits had the same histological characteristics as the invasive SPC of the nipple. The invasiveness of SPC can be difficult to determine. However, the tumor cell nests in the current case exhibited a retraction artifact, which is known to be associated with invasive carcinoma and a poor prognosis, as well as morphological patterns that have been previously identified as characteristic of invasive SPC. Although SPC is widely recognized as having a favorable outcome, the existence of exceptionally aggressive cases occurring in the nipple must be recognized. Additional cases of invasive SPC of the nipple are needed to analyze the clinicopathological correlation. PMID- 29580119 TI - A nationwide cohort study of the role of CHADS2 score in predicting lower extremity amputation and death among patients with peripheral arterial occlusive disease. AB - OBJECTIVES: The current study aimed to explore whether the CHADS2 score was predictive of lower extremity amputation (LEA) and death in people with peripheral arterial occlusive disease (PAOD). METHODS: This nationwide cohort came from Taiwan, with 16,888 PAOD patients, from 2000 through 2011, extracted from the Longitudinal Health Insurance Database 2000. Cox proportional hazard regression models were employed to identify the LEA and mortality risk according to CHADS2 score. The discriminatory properties of the score in predicting the outcomes were quantified by the area under the receiver operating characteristic curve (AUROC) and the Cox C-index. RESULTS: The AUROC of the CHADS2 score in predicting LEA and death were 0.75 (95% CI = 0.73-0.77) and 0.70 (95% CI = 0.69 0.71), respectively. The CHADS2 score had an acceptable stratification capacity for LEA (C-index = 0.79) and death (C-index = 0.76) based on Cox-regression analysis. CONCLUSIONS: This study correlates the CHADS2 score with risk of developing LEA and death in patients with PAOD. The acceptable discriminative power of the score diversifies its predictive role in this population.

AB - PURPOSE: We recently demonstrated the efficacy of tadalafil treatment for fetal growth restriction (FGR). This study aimed to evaluate the utility of serum placental growth factor (PlGF) level for predicting the efficacy of tadalafil for the treatment of FGR. MATERIALS AND METHODS: The correlations between serum level of PlGF and fetal growth velocity were retrospectively assessed in nine pregnant women receiving tadalafil for FGR before 30 weeks' gestation. RESULTS: Median gestational age was 26 weeks (range 26-28 weeks), and median deviation of estimated fetal weight from standard weight was -2.1 standard deviations (SD) ( 2.2 to -1.9 SD) at the beginning of tadalafil treatment. The median serum PlGF level was 227 pg/ml (40.2-427.0 pg/ml) before tadalafil treatment and 278 pg/ml (66.2-729.5 pg/ml) more than 2 weeks after initiation of tadalafil treatment (median gestational week at measurement of PlGF after treatment, 33 weeks [28-33 weeks]). The median fetal growth velocity from enrollment to birth was 17.5 g/day (12.1-20.3 g/day). Maternal serum PlGF levels were increased after tadalafil treatment in all nine cases (median increase in PlGF, 73.1 pg/ml [26.0-281.5 pg/ml]). Notably, maternal serum PlGF level before tadalafil treatment significantly correlated with fetal growth velocity (R2 = 0.63, p < .01). CONCLUSIONS: Tadalafil treatment may increase maternal serum PlGF levels. Our results suggest that maternal serum PlGF levels can be used as a predictor of the efficacy of tadalafil treatment for FGR.

PMID- 29580121 TI - Depletion of reactive oxygen species induced by chlorogenic acid triggers apoptosis-like death in Escherichia coli. AB - Chlorogenic acid (CGA) is a phenolic compound with various health-promoting properties, including antioxidant effects and a wide range of antibacterial activities. However, the antibacterial mechanism remains unclear. We investigated the underlying mode of action of CGA against Escherichia coli, which shows bacterial apoptosis-like death. Cells treated with CGA showed apoptotic features such as membrane depolarisation, caspase-like protein expression, increased intracellular Ca2+ levels, phosphatidylserine externalisation, and DNA fragmentation. In contrast to common bacterial apoptosis-like death, which is caused by reactive oxygen species (ROS) accumulation, CGA depleted intracellular ROS. Because ROS are important intracellular signalling molecules, and ROS depletion may affect bacterial intracellular signalling pathways, leading to cell death. To determine whether deficiencies in intracellular ROS cause apoptosis like death, the cells were treated with H2O2 after CGA treatment. H2O2 restored depleted intracellular ROS levels to similar levels as in untreated cells, and cell viability was increased compared to CGA-treated cells. Moreover, apoptotic features were attenuated in H2O2 post-treated cells. These results demonstrate that CGA induces bacterial apoptosis in E. coli and intracellular ROS depletion is a core regulator in the progression of bacterial apoptosis-like death. PMID- 29580123 TI - Ethnic and racial difference in Helicobacter pylori infection in patients with immune thrombocytopenia treated at a major urban medical center. AB - Immune thrombocytopenia (ITP) is an autoimmune disorder with a complex immunopathology and pathogenesis characterized by thrombocytopenia and bleeding manifestations. The disorder is separated into primary (idiopathic) ITP and secondary ITP, when associated with other immune or lymphoproliferative disorders and certain chronic infections. Helicobacter pylori (H. pylori) is a recognized bacterial cause of ITP. In regions with high prevalence of infection, bacterial eradication has resulted in improvement in platelet count. However, the prevalence of H. pylori infection and response to antimicrobial therapy in North American ITP patients is reportedly low. We evaluated the prevalence of H. pylori infection in ITP patients diagnosed and treated at a large urban medical center. Eighty-two patients were screened for H. pylori, by stool antigen (n = 54), H. pylori breath test (n = 11), and H. pylori antibodies (n = 16), of which 15 (18.3%) were white non-Hispanic (WNH), 55 (67%) Hispanic (H), 8 (9.8%) Asian (A), and 4 (4.9%) African-American (AA). Of the screened patients, 36/82 (43.9%) tested positive for H. pylori. The prevalence of H. pylori infection within the represented ethnic groups was 2/15 (13%) WNH, 29/55 (52.7%) H, 3/8 (37.5%) A, and 2/4 (50%) AA. There was a significant difference in prevalence of infection comparing WNH and H patients (p = 0.007). There were 36 treated patients, with H. pylori eradication documented in 26 patients. Fifteen of the 26 patients were evaluable for response with 8 of 15 (53%) having clinical responses, 6 complete responses, and 2 partial responses. Our study demonstrates an increased prevalence of H. pylori infection in the Hispanic ITP population with a reasonable platelet response among patients with H. pylori eradication.

PMID- 29580127 TI - Epithelial sodium channel blockade and new beta-ENaC polymorphisms among normotensive and hypertensive adult Nigerians. AB - We sought to determine the effect of amiloride on blood pressure (BP) and the presence of polymorphisms of the beta-subunit of the epithelial sodium channel (ENaC) among normotensive (NT) and hypertensive (HT) Nigerians. Healthy volunteers-47 NT and 53 age-matched HT were recruited after giving informed consent. Subjects were salt-loaded with 200 mmol of NaCl daily for 5 days. Following a week washout period, salt-loading was repeated in addition to the administration of 5 mg amiloride daily for five days. Blood pressure, plasma and urine electrolytes were measured at baseline, after salt-loading and after salt loading plus amiloride. PCR amplicons were sequenced for beta-ENaC polymorphisms. Salt-loading led to a significant increase (p < 0.05) in SBP among NT and HT and in DBP (p < 0.001) only among HT. Amiloride reduced SBP and DBP to below baseline levels in NT (p < 0.05) and HT (p < 0.001) subjects. Five of the subjects had the beta-T594M polymorphism, HT 3/53; NT 2/47 (p = 0.75). Four previously unreported beta-ENaC mutations were recorded: E632V and E636V, respectively, among two HT subjects, D638Y in another HT and L628Q in one NT subject. We showed the presence of beta-ENaC polymorphisms among our populace and the possible usefulness of amiloride as a single antihypertensive among Nigerians. PMID- 29580128 TI - Breast cancer lung metastasis: Molecular biology and therapeutic implications. AB - Distant metastasis accounts for the vast majority of deaths in patients with cancer. Breast cancer exhibits a distinct metastatic pattern commonly involving bone, liver, lung, and brain. Breast cancer can be divided into different subtypes based on gene expression profiles, and different breast cancer subtypes show preference to distinct organ sites of metastasis. Luminal breast tumors tend to metastasize to bone while basal-like breast cancer (BLBC) displays a lung tropism of metastasis. However, the mechanisms underlying this organ-specific pattern of metastasis still remain to be elucidated. In this review, we will summarize the recent advances regarding the molecular signaling pathways as well as the therapeutic strategies for treating breast cancer lung metastasis. PMID- 29580129 TI - Bidirectional influence of amygdala beta1-adrenoceptors blockade on cannabinoid signaling in contextual and auditory fear memory. AB - The basolateral amygdala (BLA) is a major target and modulator of stress and has a critical role in the neural circuitry presenting learned fear behaviors. On the other hand, both the endocannabinoid and noradrenergic systems may be involved in regulating the stress responses, fear, and anxiety. Considering the aforementioned, we have investigated the involvement of the BLA beta1 adrenoceptors in conditioned fear responses induced by ACPA, a CB1 receptor (CB1R) agonist. In adult male NMRI mice, freezing responses to context and cue were measured using a Pavlovian fear conditioning apparatus. Pre-training intra BLA microinjection of xamoterol (0.01 and 0.02 ug/mouse), a partial beta1 adrenoceptor agonist, or atenolol (0.5 ug/mouse), a beta1-adrenoceptor antagonist, decreased freezing behavior, which suggests an impairment of contextual and auditory fear retrieval. Similar results were found with pre training intraperitoneal administration of ACPA (0.5 mg/kg). A sub-threshold dose of xamoterol, infused into the BLA, decreased ACPA (0.005 and 0.05 mg/kg) effect on both memories, while atenolol increased ACPA response to the context at the middle dose and decreased ACPA response to the tone at the lower dose. It can be concluded that the blockade of BLA beta1-adrenoceptors differentially affects ACPA response on the contextual and auditory conditioned fear memories. PMID- 29580130 TI - Repeated intermittent oral amphetamine administration results in locomotor tolerance not sensitization. AB - BACKGROUND: The phenomenon of locomotor sensitization to injected amphetamine is well-characterised. The increased locomotor activity found acutely is enhanced with repeated intermittent treatment. This effect arises due to hypersensitization of the dopaminergic system and is linked to drug addiction. A clinical population exposed to chronic repeated intermittent amphetamine treatment, such as is found for attention deficit hyperactivity disorder (ADHD), may be expected to be more at risk of addiction following this treatment. However, evidence suggests the opposite may be true. This suggests the route of administration may determine the direction of effects. AIMS AND METHODS: We aimed to establish how an oral amphetamine treatment regimen, similar to that used in ADHD, impacts on locomotor activity, specifically whether tolerance or sensitization would arise. Healthy hooded Lister rats were given amphetamine (2 mg/kg, 5 mg/kg and 10 mg/kg) or a vehicle solution once daily for 4 weeks with a 5 day on, 2 day off schedule. Locomotor activity was measured on the first day of treatment to establish the acute effects and on the final day of treatment to examine the chronic effects. RESULTS: As expected, acute doses of amphetamine increased locomotor activity, although this only reached statistical significance for the 5 mg/kg and 10 mg/kg doses. By contrast, after chronic treatment, animals administered these doses showed reduced activity indicating drug tolerance rather than sensitization had occurred. CONCLUSION: We suggest that the route of administration used in ADHD, which results in more stable and longer duration drug levels in the blood, results in tolerance rather than sensitization and that this effect could explain the reduced likelihood of substance addiction in those treated with psychostimulants for ADHD. PMID- 29580131 TI - How Do Allied Health Professionals Define and Apply Equity When Making Resource Allocation Decisions? AB - An ethnographic study was conducted in 2 stages to understand how allied health professionals define and apply equity when making resource allocation decisions. Participants were allied health managers and clinicians from Victoria, Australia. Stage 1 included 4 semi-structured forums that incorporated real-life case studies, group discussions, and hypothetical scenarios. The project's steering committee began a thematic analysis during post-forum discussions. Stage 2 included a key stakeholder working party that further discussed the concept of equity. The forum recordings were transcribed verbatim, and a detailed thematic analysis ensured the initial thematic analysis was complete. Several domains of equity were discussed. Participants would readily identify that equity was a consideration when making resource decisions but were generally silent for a prolonged period when prompted to identify what they meant when using this term. The findings indicate that asking allied health professionals to directly state how they define and apply equity to their decision-making could be too difficult a task, as this did not elicit rich and meaningful discussions. Future research should examine individual domains of equity when applied to resource allocation decisions. PMID- 29580132 TI - Learning "Math on the Move": Effectiveness of a Combined Numeracy and Physical Activity Program for Primary School Children. AB - BACKGROUND: Physically active learning that combines physical activity with core curriculum areas is emerging in school-based health interventions. This study investigates the effectiveness of learning an important numeracy skill of times tables (TT) while concurrently engaging in aerobic activity compared with a seated classroom approach. METHODS: Grade-4 primary school students were randomly allocated to physical activity (P) or classroom (C) groups and received the alternate condition in the following term. P group received moderate to vigorous exercise (20 min, 3 times per week, 6 wk) while simultaneously learning selected TT. C group received similar learning, but seated. Changes in TT accuracy, general numeracy, aerobic fitness, and body mass index were assessed. Data were expressed as mean (SEM) and between-condition effect size (ES; 95% confidence interval). RESULTS: Participants [N = 85; 55% male, 9.8 (0.3) y, 36.4% overweight/obese] improved similarly on TT in both conditions [C group: 2.2% (1.1%); P group: 2.5% (1.3%); ES = 0.03; -0.30 to 0.36; P = .86]. Improvement in general numeracy was significantly greater for P group than C group [C group: 0.7% (1.2%); P group: 5.3% (1.4%); ES = 0.42; 0.08 to 0.75; P < .03]. An improvement in aerobic fitness for P group (P < .01) was not significantly greater than C group [C group: 0.8 (0.6); P group: 2.2 (0.5) mL.kg.min-1; ES = 0.32; -0.01 to 0.66; P = .06]. Body mass index was unchanged. CONCLUSION: Combined movement with learning TT was effective. Physically active learning paradigms may contribute to meeting daily physical activity guidelines while supporting or even boosting learning. PMID- 29580133 TI - Time interval of revaccination with 23-valent pneumococcal polysaccharide vaccine more than 5 years does not affect the immunogenicity and safety in the Japanese elderly. AB - In the previous study, revaccination with 23-valent pneumococcal polysaccharide vaccine (PPSV23) in a total of 161 elderly subjects (>=70 years of age) who had received the initial vaccination at least 5 years before (range: 5 to11 years) showed an acceptable safety profile and induction of immune responses to the serotypes in PPSV23. The optimal interval between the initial vaccination and revaccination with PPSV23 is of interest to protect elderly from pneumococcal disease over the long-term. In this post-hoc analysis, we analyzed that the immunogenicity and safety of revaccination with PPSV23 by time interval after the initial vaccination. The level of serotype-specific immunoglobulin G (IgG) geometric mean concentrations (GMCs) and opsonophagocytic killing activity (OPA) geometric mean titers (GMTs) at 4 weeks after revaccination with PPSV23 in each subgroup based on time interval (5, 6, 7, 8 and 9-11 years) after the initial vaccination were comparable to those after the primary vaccination and vaccine induced serotype-specific IgG and OPA levels were similar regardless of the time interval after the initial vaccination. There was no difference in the safety profiles among the subgroups. In conclusion, administration of a second dose of PPSV23 at least 5 years after the initial vaccination was immunogenic and well tolerated in the elderly >=70 years of age regardless of the time interval after the initial vaccination. PMID- 29580134 TI - Low- and High-Volume Water-Based Resistance Training Induces Similar Strength and Functional Capacity Improvements in Older Women: A Randomized Study. AB - BACKGROUND: Water-based resistance training (WRT) has been indicated to promote strength gains in elderly population. However, no study has compared different training strategies to identify the most efficient one. The aim of this study was to compare the effects of 3 WRT strategies on the strength and functional capacity of older women. METHODS: In total, 36 women were randomly allocated to training groups: simple set of 30 seconds [1 * 30s; 66.41 (1.36) y; n = 12], multiple sets of 10 seconds [3 * 10s; 66.50 (1.43) y; n = 11], and simple set of 10 seconds [1 * 10s; 65.23 (1.09) y; n = 13]. Training lasted for 12 weeks. The maximal dynamic strength (in kilograms) and muscular endurance (number of repetitions) of knee extension, knee flexion, elbow flexion, and bench press, as well as functional capacity (number of repetitions), were evaluated. RESULTS: All types of training promoted similar gains in maximal dynamic strength of knee extension and flexion as well as elbow flexion. Only the 1 * 30s and 1 * 10s groups presented increments in bench press maximal strength. All 3 groups showed increases in muscular endurance in all exercises and functional capacity. CONCLUSIONS: WRT using long- or short-duration simple sets promotes the same gains in strength and functional capacity in older women as does WRT using multiple sets. PMID- 29580135 TI - Understanding the Nature of Measurement Error When Estimating Energy Expenditure and Physical Activity via Physical Activity Recall. AB - BACKGROUND: The National Health and Nutrition Examination Survey physical activity questionnaire (PAQ) is used to estimate activity energy expenditure (AEE) and moderate to vigorous physical activity (MVPA). Bias and variance in estimates of AEE and MVPA from the PAQ have not been described, nor the impact of measurement error when utilizing the PAQ to predict biomarkers and categorize individuals. METHODS: The PAQ was administered to 385 adults to estimate AEE (AEE:PAQ) and MVPA (MVPA:PAQ), while simultaneously measuring AEE with doubly labeled water (DLW; AEE:DLW) and MVPA with an accelerometer (MVPA:A). RESULTS: Although AEE:PAQ [3.4 (2.2) MJ.d-1] was not significantly different from AEE:DLW [3.6 (1.6) MJ.d-1; P > .14], MVPA:PAQ [36.2 (24.4) min.d-1] was significantly higher than MVPA:A [8.0 (10.4) min.d-1; P < .0001]. AEE:PAQ regressed on AEE:DLW and MVPA:PAQ regressed on MVPA:A yielded not only significant positive relationships but also large residual variances. The relationships between AEE and MVPA, and 10 of the 12 biomarkers were underestimated by the PAQ. When compared with accelerometers, the PAQ overestimated the number of participants who met the Physical Activity Guidelines for Americans. CONCLUSIONS: Group-level bias in AEE:PAQ was small, but large for MVPA:PAQ. Poor within-participant estimates of AEE:PAQ and MVPA:PAQ lead to attenuated relationships with biomarkers and misclassifications of participants who met or who did not meet the Physical Activity Guidelines for Americans. PMID- 29580137 TI - Natural Diversity in Heat Resistance of Bacteria and Bacterial Spores: Impact on Food Safety and Quality. AB - Heat treatments are widely used in food processing often with the aim of reducing or eliminating spoilage microorganisms and pathogens in food products. The efficacy of applying heat to control microorganisms is challenged by the natural diversity of microorganisms with respect to their heat robustness. This review gives an overview of the variations in heat resistances of various species and strains, describes modeling approaches to quantify heat robustness, and addresses the relevance and impact of the natural diversity of microorganisms when assessing heat inactivation. This comparison of heat resistances of microorganisms facilitates the evaluation of which (groups of) organisms might be troublesome in a production process in which heat treatment is critical to reducing the microbial contaminants, and also allows fine-tuning of the process parameters. Various sources of microbiological variability are discussed and compared for a range of species, including spore-forming and non-spore-forming pathogens and spoilage organisms. This benchmarking of variability factors gives crucial information about the most important factors that should be included in risk assessments to realistically predict heat inactivation of bacteria and spores as part of the measures for controlling shelf life and safety of food products. PMID- 29580138 TI - Stability and Stabilization of Enzyme Biosensors: The Key to Successful Application and Commercialization. AB - Fifty-five years have passed and more than 100,000 articles have been published since the first report of an electrochemical enzyme biosensor. However, very few biosensors have reached practical application and commercialization. The bulk of the research effort has been on increasing sensitivity and selectivity. In contrast, the number of publications dealing with stability or stabilization of enzyme biosensors is very small. Here, we critically review enzyme stabilization strategies as well as the progress that has been done in the past 20 years with respect to enzyme biosensor stabilization. Glucose oxidase, lactate oxidase, alcohol oxidase, and xanthine oxidase are the focus of this review because of their potential applications in food. The inconsistency in reporting biosensor stability was identified as a critical hurdle to research progress in this area. Fundamental questions that remain unanswered are outlined. PMID- 29580139 TI - Use of Natural Selection and Evolution to Develop New Starter Cultures for Fermented Foods. AB - The fermented foods industry is constantly seeking new starter cultures to deal with changing consumer preferences and new fermentation processes. New cultures can either be composed of strains isolated from nature or improved derivatives of existing isolates. A variety of techniques involving natural selection and evolution are available to enhance the performance of existing strains, including the isolation of mutants with desired properties, adaptive laboratory evolution, genome shuffling, and genome editing. Numerous examples of traits that can be improved are provided. These include resistance to bacteriophages; the secretion of glucose to increase sweetness; the production of vitamins, antifungal compounds, bacteriocins, texture, or aroma; enhancement of acidification rates and acid tolerance; and elimination of biofilm formation. Careful consideration is required to ensure the developed strains are suitable for the desired purpose, as some approaches may lead to regulatory concerns. PMID- 29580136 TI - Milk Glycans and Their Interaction with the Infant-Gut Microbiota. AB - Human milk is a unique and complex fluid that provides infant nutrition and delivers an array of bioactive molecules that serve various functions. Glycans, abundant in milk, can be found as free oligosaccharides or as glycoconjugates. Milk glycans are increasingly linked to beneficial outcomes in neonates through protection from pathogens and modulation of the immune system. Indeed, these glycans influence the development of the infant and the infant-gut microbiota. Bifidobacterium species commonly are enriched in breastfed infants and are among a limited group of bacteria that readily consume human milk oligosaccharides (HMOs) and milk glycoconjugates. Given the importance of bifidobacteria in infant health, numerous studies have examined the molecular mechanisms they employ to consume HMOs and milk glycans, thus providing insight into this unique enrichment and shedding light on a range of translational opportunities to benefit at-risk infants. PMID- 29580140 TI - Uptake of Engineered Nanoparticles by Food Crops: Characterization, Mechanisms, and Implications. AB - With the rapidly increasing demand for and use of engineered nanoparticles (NPs) in agriculture and related sectors, concerns over the risks to agricultural systems and to crop safety have been the focus of a number of investigations. Significant evidence exists for NP accumulation in soils, including potential particle transformation in the rhizosphere and within terrestrial plants, resulting in subsequent uptake by plants that can yield physiological deficits and molecular alterations that directly undermine crop quality and food safety. In this review, we document in vitro and in vivo characterization of NPs in both growth media and biological matrices; discuss NP uptake patterns, biotransformation, and the underlying mechanisms of nanotoxicity; and summarize the environmental implications of the presence of NPs in agricultural ecosystems. A clear understanding of nano-impacts, including the advantages and disadvantages, on crop plants will help to optimize the safe and sustainable application of nanotechnology in agriculture for the purposes of enhanced yield production, disease suppression, and food quality. PMID- 29580141 TI - Lactic Acid Bacteria Exopolysaccharides in Foods and Beverages: Isolation, Properties, Characterization, and Health Benefits. AB - Exopolysaccharides produced by lactic acid bacteria are a diverse group of polysaccharides produced by many species. They vary widely in their molecular, compositional, and structural characteristics, including mechanisms of synthesis. The physiochemical properties of these polymers mean that they can be exploited for the sensorial and textural enhancement of a variety of food and beverage products. Traditionally, lactic acid bacteria exopolysaccharides have an important role in fermented dairy products and more recently are being applied for the improvement of bakery products. The health benefits that are continually being associated with these polysaccharides enable the development of dual function, added-value, and clean-label products. To fully exploit and understand the functionality of these exopolysaccharides, their isolation, purification, and thorough characterization are of great importance. This review considers each of the above factors and presents the current knowledge on the importance of lactic acid bacteria exopolysaccharides in the food and beverage industry. PMID- 29580142 TI - A rare case of multicentric castleman's disease transforms into multiple myeloma and its successful treatment. AB - Multicentric Castleman's disease (MCD) is a rare kind of lymphoproliferative disorder characterized by systemic problems such as frequent fever, fatigue and weight loss with angiofollicular lymph node hyperplasia. However, unlike unicentric Castleman's disease (UCD) with long-time survival by surgery and local radiotherapy, MCD remains poor prognosis due to no well-defined optimal treatment strategies and high risk of developing malignances especially lymphoma. We reported a case of MCD who received chemotherapy by ECHOP with unsatisfactory outcome and then oral administration with thalidomide combined with prednisone without disease progression after therapy. After 3 y, his MCD turned into multiple myeloma (MM) and accompanied by obvious response to combination of thalidomide with prednisone. Nowadays, there is no standard of therapy yet established for MCD. We successfully treated one such patient and found thalidomide based therapy may have a significant effect on MCD. We also proposed further researches with therapeutic potential about thalidomide for MCD. PMID- 29580143 TI - MiR-135a-5p represses proliferation of HNSCC by targeting HOXA10. AB - OBJECTIVES: This research aimed to explore the role of miR-135a-5p in head and neck squamous cell carcinoma (HNSCC) cells and its influence on cell viability. Moreover, we aimed to compare effects of miR-135a-5p and miR-494 in HNSCC, which was found to repress HOXA10 expression in oral cancer. METHODS: The association between miR-135a-5p and HOXA10 was confirmed by green fluorescence protein reporter assay and qRT-PCR. The expression levels of HOXA10 in HNSCC cell lines (CAL-27, FaDu and NEC) were examined using western blot. The expression levels of HOXA10 in FaDu cells and CAL-27 cells were examined by western blot after transfection with miR-135a-5p mimics and miR-494 mimics. Colony formation assay and flow cytometry assay were respectively utilized to detect the proliferation and apoptosis of HNSCC cells after transfection with HOXA10 plasmids and HOXA10 KO plasmids. In vitro tumor xenograft experiments were performed to analyze the inhibitive effect of miR-135a-5p on HOXA10 in BALA/c mice. RESULTS: HOXA10 was overexpressed in HNSCC cells, while miR-135a-5p was under-expressed. Therefore, low expression of HOXA10 lengthened disease-free survival time and overall survival time. MiR-135a-5p overexpression could inhibit HOXA10 expression by directly targeting HOXA10 3'UTR, and the inhibition was more effective than miR 494. HOXA10 suppression inhibited proliferation and enhanced apoptosis of HNSCC cells. In vivo experiments showed that miR-135a-5p could decelerate the growth of tumor cells in mice by downregulating HOXA10 expression. CONCLUSION: MiR-135a-5p could repress HNSCC cells proliferation and enhance apoptosis by directly targeting HOXA10, implying miR-135a-5p's significance on HNSCC treatment. PMID- 29580144 TI - Natural dietary compound naringin prevents azoxymethane/dextran sodium sulfate induced chronic colorectal inflammation and carcinogenesis in mice. AB - : Naringin, a natural occurring flavonoid compound, enriches in citrus fruits. We aimed to evaluate the inhibitory effect of naringin on colitis and chronic inflammation-driven carcinogenesis. Male C57BL/6 mice were exposed to AOM/DSS to induce colorectal inflammation and carcinogenesis. Naringin by oral administration prevented AOM/DSS-induced ulcerative colitis and carcinogenesis without significant side effects. Naringin attenuated the severity of colitis and colorectal adenomas through inhibiting myeloid-derived suppressor cells (MDSCs), pro-inflammatory mediators GM-CSF/M-CSF, IL-6 and TNF-alpha and the NF-kappaB/IL 6/STAT3 cascades in colorectal tissues. Naringin-treated mice exhibited normalized structures of colorectal tissues. Electron microscopy analysis showed the suppression of robust endoplasmic reticulum (ER) stress-induced autophagy. Naringin inhibited the secretion of the ER-spanning transmembrane proteins, such as GRP78 ATF6, IRE1alpha and activated PERK phosphorylated eIF-2alpha and complex of autophagosomes ATG3, ATG5, ATG7, ATG12, ATG16 and ATG16L1 in the colorectal mucosal cells. CONCLUSION: Naringin prevented colitis and colorectal carcinogenesis through suppressing robust ER stress-induced autophagy in colorectal mucosal cells. Naringin could develop a promising therapeutic agent for the prevention of ulcerative colitis and colorectal tumor. PMID- 29580146 TI - Segregating the Distinct Effects of Sedentary Behavior and Physical Activity on Older Adults' Cardiovascular Profile: Part 2-Isotemporal Substitution Approach. AB - BACKGROUND: The aim of the study was to provide an isotemporal substitution model to predict how changes in physical behavior may affect the cardiovascular parameters (CVPs) of older adults. METHODS: Participants wore a thigh-mounted accelerometer for 7 days. Phenotype of the carotid, brachial, and popliteal artery was conducted using ultrasound. Isotemporal substitution was used to simulate the degree to which replacing 1 hour of physical behavior with another would affect CVP. RESULTS: Substitution of sedentary behavior with Standing and sporadic moderate- to vigorous-intensity physical activity (MVPA accumulated in bouts <10 min) would reduce resting heart rate [-6.20 beats per minute (-12.1 to 0.22) and -3.72 beats per minute (-7.01 to -0.44), respectively]. Substitution of sedentary behavior with light-intensity physical activity would reduce carotid artery diameter [-0.54 mm (-1.00 to -0.07)]. Substitution of Standing with sporadic MVPA would increase popliteal artery diameter [1.31 mm (0.11 to 2.51)]. CONCLUSIONS: Our modeling suggests that an accumulation of MVPA bouts that are shorter than the recommended 10-minute minimum may still improve CVP, with lower intensity physical activity also influencing CVP. Our findings are a promising avenue for lifestyle interventions in older adults to reduce the aging effects on CVP for those who cannot engage or sustain sufficient MVPA. PMID- 29580145 TI - Ovarian dysgerminoma in pregnancy: A case report and literature review. AB - BACKGROUND: Dysgerminoma is an uncommon malignant tumor arising from the germ cells of the ovary. Its association with pregnancy is extremely rare; the incidence is about 0.2-1 per 100,000 pregnancies. Because of its infrequency, there are few recommendations regarding its management in pregnancy; therefore, it is important to discuss and summarize the treatment strategy. CASE: We presented a case of a 23-year-old pregnant woman with a large dysgerminoma originated from the right ovary, which had the unusual coincidence of being associated with an abdominal desmoid tumor simultaneously. We did not find any similar cases published in the PubMed database after 1947. A cesarean section was performed at 34 + 6 weeks gestation secondary to her abdominal pain worsening. The patient delivered a healthy boy and had fertility-preserving surgery, followed by 6 cycles of chemotherapy. This case is compared with 21 other reported cases of pure ovarian dysgerminoma in the literature to evaluate the clinical characteristics, feto-maternal compromise, treatment, long-term survival, and fertility outcome. CONCLUSION: The treatment strategy in women with ovarian dysgerminoma should be discussed and structured on an individual basis. If pregnancy is desired, surgical intervention undertaken in the second trimester seems to be the first choice. When chemotherapy is indicated, unless delivery can be accomplished within a few weeks of diagnosis, it should not necessarily be delayed until after delivery. Good reproductive function and high survival rate can be achieved in patients treated with conservative surgery and adjuvant chemotherapy. PMID- 29580147 TI - Early brain metastasis of advanced gastric cancer with a pathological complete response to neoadjuvant chemotherapy followed by surgery: A case report and literature review. AB - Advanced gastric cancer with a pathological complete response to neoadjuvant chemotherapy and surgery followed by early brain metastasis is rare. A 52-y-old male patient who was diagnosed with advanced gastric cancer (cT4N2M0, stage SHB). Radiological examinations after three cycles of preoperative chemotherapy with a modified FOLFOX6 (mFOLFOX6) regimen showed a partial response (PR) had been achieved. The patient underwent curative surgery consisting of proximal gastrectomy, and D2 lymph node dissection. The lack of abnormal gastric cancer cells in the primary lesion or lymph nodes confirmed a pathological complete response (pCR). Postoperative chemotherapy with oral S-1 was administrated. However, during the second cycles of postoperative chemotherapy, the patient experienced headaches, projectile vomiting and convulsion. Upon further examination, a tumor representing metastasis to the brain was recognized by cranial enhanced magnetic resonance imaging (MRI) examination and cytopathology of cerebrospinal fluid. In addition to documenting the case report, we reviewed the literature associated to features of metastatic brain malignancies that form from gastric cancer. In short, advanced gastric cancer patents achieved pCR after preoperative chemotherapy typically have good prognosis; however, great attention should be paid on detecting metastatic events.

AB - A Massive Open Online Course, Dying2Learn, was designed to foster community death conversations and strengthen community awareness of palliative care and death as a normal process. This exploratory study used a pre-post prospective design to determine if participation in Dying2Learn and exposure to online conversations about death and dying resulted in any significant influence on death competence in 134 participants who completed the Coping-with-Death-Scale both at the beginning and end of the course in 2016. Death competence refers to a range of attitudes and capabilities people have for dealing with death. Results at the end of the course indicated that engagement in Dying2Learn led to significant improvements in death competence scores over time (medium-to-large effect size). The positive impact was greater for those who completed more of the course, and effectiveness did not depend on sociodemographic characteristics. In conclusion, this study found that an online learning platform in the form of a Massive Open Online Course could engage community members in meaningful social discussion about death and dying, and that exposure to these conversations was beneficial for all participants regardless of previous exposure to death. Further exploration is required to determine whether this change in death competence will have an impact on participant's behavior in the community regarding death conversations and preparedness. PMID- 29580150 TI - Embodied Interaction Priority: Other's Body Part Affects Numeral-Space Mappings. AB - Traditionally, the spatial-numerical association of response codes (SNARC) effect was presented in two-choice condition, in which only one individual reacted to both even (small) and odd (large) numbers. Few studies explored SNARC effect in a social situation. Moreover, there are many reference frames involved in SNARC effect, and it has not yet been investigated which reference frame is dominated when two participants perform the go-nogo task together. In the present study, we investigated which reference frame plays a primary role in SNARC effect when allocentric and egocentric reference frames were consistent or inconsistent in social settings. Furthermore, we explored how two actors corepresent number-space mapping interactively. Results of the two experiments demonstrated that egocentric reference frame was at work primarily when two reference frames were consistent and inconsistent. This shows that body-centered coordinate frames influence number-space mapping in social settings, and one actor may represent another actor's action and tasks. PMID- 29580149 TI - A novel BRCA2 mutation in prostate cancer sensitive to combined radiotherapy and androgen deprivation therapy. AB - Genetic factors contribute to more than 40% of prostate cancer risk, and mutations in BRCA1 and BRCA2 are well-established risk factors. By using target capture-based deep sequencing to identify potential pathogenic germline mutations, followed by Sanger sequencing to determine the loci of the mutations, we identified a novel pathogenic BRCA2 mutation caused by a cytosine-to-guanine base substitution at position 4211, resulting in protein truncation (p.Ser1404Ter), which was confirmed by immunohistochemistry. Analysis of peripheral blood also identified benign polymorphisms in BRCA2 (c.7397T>C, p.Val2466Ala) and SRD5A2 (c.87G>C, p.Lys29Asn). Analysis of tumor tissues revealed seven somatic mutations in prostate tumor tissue and nine somatic mutations in esophageal squamous carcinoma tissue (single nucleotide polymorphisms, insertions, and deletions). Five-year follow-up results indicate that ADT combined with radiotherapy successfully treated the prostate cancer. To our knowledge, we are the first to report the germline BRCA2 mutation c.4211C>G (p.Ser1404Ter) in prostate cancer. Combined ADT and radiotherapy may be effective in treating other patients with prostate cancer caused by this or similar mutations. PMID- 29580151 TI - Effects of Facial Skin Smoothness and Blemishes on Trait Impressions. AB - People make trait inferences based on facial appearance, and these inferences guide social approach and avoidance. Here, we investigate the effects of textural features on trait impressions from faces. In contrast to previous work, which exclusively manipulated skin smoothness, we manipulated smoothness and the presence of skin blemishes independently (Study 1) and orthogonally (Study 2). We hypothesized that people are particularly sensitive to skin blemishes because blemishes potentially indicate poor health and the presence of an infectious disease. We therefore predicted that the negative effect of blemished skin is stronger than the positive effect of smoothed skin. The results of both studies are in line with this reasoning. Across ratings of trustworthiness, competence, maturity, attractiveness, and health, the negative influence of skin blemishes was stronger and more consistent than the positive influence of skin smoothness (Study 1). Moreover, the presence of skin blemishes diminished the positive effect of skin smoothness on attractiveness ratings (Study 2). In sum, both facial skin blemishes and facial skin smoothness influence trait impression, but the negative effect of blemished skin is larger and more salient than the positive effect of smooth skin. PMID- 29580152 TI - Epidemiology, risk factors, and clinical outcomes in severe microbial keratitis in South India. AB - PURPOSE: Here, we report risk factors associated with outcome in severe bacterial keratitis (BK), fungal keratitis (FK), and Acanthamoeba keratitis (AK) in India. METHODS: Prospective observational cohort study conducted in Aravind Eye Hospital, India. Adults presenting with severe microbial keratitis (MK) were enrolled (size >=3 mm) and followed to 21 days post-enrolment. Ulcer clinical features were recorded at presentation. Outcomes by final visit were classified as good (completely healed or reduced infiltrate size) or poor (enlarged infiltrate size, perforated, or surgery performed). RESULTS: Of 252 participants with severe MK, 191 had FK, 18 had AK, 19 had BK, 4 had mixed BK/FK, and 20 were microbiologically negative. Median age was 50 years (interquartile range [IQR]: 37-60 years), 64% were male, 63% were agriculturalists, and 45% had no formal education. Corneal trauma occurred in 72%, and median symptom duration before presentation was 7 days (IQR: 5-15 days). Clinical features associated with FK were feathery margins (p < 0.001), raised profile (p = 0.039), or dry surface (p = 0.007). Hypopyon was more likely in BK (p = 0.001) and ring infiltrate in AK (p < 0.001). Ulcers with poor outcome (n = 106/214) were more likely to be larger (odds ratio [OR]: 1.63, 95% confidence interval [CI]: 1.30-2.05, p < 0.001), involve the posterior cornea at presentation (OR: 2.31, 95% CI: 1.16-4.59, p = 0.017), involve Aspergillus sp. (OR: 3.23, 95% CI: 1.26-8.25, p = 0.014), or occur in females (OR: 2.04, 95% CI: 1.03-4.04, p = 0.04). Even after treatment, 34% (n = 76/221) had severe visual impairment by the final visit. CONCLUSIONS: Severe MK occurred predominantly in agriculturalists post-corneal trauma and often had poor outcomes. Provision of community-based eyecare may allow earlier treatment and improve outcomes. PMID- 29580153 TI - Peripheral nerve injury increases contribution of L-type calcium channels to synaptic transmission in spinal lamina II: Role of alpha2delta-1 subunits. AB - Background Following peripheral nerve chronic constriction injury, the accumulation of the alpha2delta-1 auxiliary subunit of voltage-gated Ca2+ channels in primary afferent terminals contributes to the onset of neuropathic pain. Overexpression of alpha2delta-1 in Xenopus oocytes increases the opening properties of Cav1.2 L-type channels and allows Ca2+ influx at physiological membrane potentials. We therefore posited that L-type channels play a role in neurotransmitter release in the superficial dorsal horn in the chronic constriction injury model of neuropathic pain. Results Whole-cell recording from lamina II neurons from rats, subject to sciatic chronic constriction injury, showed that the L-type Ca2+ channel blocker, nitrendipine (2 uM) reduced the frequency of spontaneous excitatory postsynaptic currents. Nitrendipine had little or no effect on spontaneous excitatory postsynaptic current frequency in neurons from sham-operated animals. To determine whether alpha2delta-1 is involved in upregulating function of Cav1.2 L-type channels, we tested the effect of the alpha2delta-1 ligand, gabapentin (100 uM) on currents recorded from HEK293F cells expressing Cav1.2/beta4/alpha2delta-1 channels and found a significant decrease in peak amplitude with no effect on control Cav1.2/beta4/alpha2delta-3 expressing cells. In PC-12 cells, gabapentin also significantly reduced the endogenous dihydropyridine-sensitive calcium current. In lamina II, gabapentin reduced spontaneous excitatory postsynaptic current frequency in neurons from animals subject to chronic constriction injury but not in those from sham-operated animals. Intraperitoneal injection of 5 mg/kg nitrendipine increased paw withdrawal threshold in animals subject to chronic constriction injury. Conclusion We suggest that L-type channels show an increased contribution to synaptic transmission in lamina II dorsal horn following peripheral nerve injury. The effect of gabapentin on Cav1.2 via alpha2delta-1 may contribute to its anti-allodynic action. PMID- 29580155 TI - Self-Compassion and the Self-Regulation of Exercise: Reactions to Recalled Exercise Setbacks. AB - Self-compassion facilitates health behavior self-regulation; few studies have examined self-compassion and exercise. This online, cross-sectional study investigated self-compassion's relationship with exercise self-regulation of an exercise setback. Adults (N = 105) who had experienced an exercise setback within the last 6 months completed baseline measures, recalled an exercise setback, and completed questionnaires assessing self-regulation in this context. Self compassion associated with self-determined motivations and exercise goal reengagement, and negatively related to extrinsic motivations, state rumination, and negative affect. Self-compassion predicted unique variance, beyond self esteem, in exercise goal reengagement, external regulation, state rumination, and negative affect experienced after an exercise setback. Self-compassion and self esteem had unique relationships with goal reengagement, state rumination, and situational motivation, while having a complementary relationship with negative affect. This research adds to the few studies that examine the role of self compassion in exercise self-regulation by examining how self-compassion and self esteem relate to reactions to a recalled exercise setback. PMID- 29580156 TI - Liquid biopsy of bile for the molecular diagnosis of gallbladder cancer. AB - INTRODUCTION: Tissue sampling of gallbladder cancer (GBCa) is challenging because of the anatomy of the gallbladder. The aim of this study is to investigate the possibility of diagnosing GBCa patients by performing a liquid biopsy of bile in addition to current diagnostic methods. METHODS: Thirty patients with GBCa were enrolled in this study. Cytological examination was performed in all patients. Using next generation sequencing (NGS), DNA isolated from the bile and tumor tissue was analyzed for mutations in 49 oncogenes. We also compared these mutations with cytology results. RESULTS: 57.1% of DNA samples from tumor tissue were positive for a mutation. In these patients, 87.5% of the bile circulating tumor DNA (ctDNA) samples had the same mutation. The concordance rate between bile ctDNA and tissue DNA samples was 85.7%, and the mutation frequencies detected in ctDNA were approximately half of what was detected in tumor tissue DNA. On the other hand, the sensitivity of the cytological and bile ctDNA analyses was 45.8% and 58.3%, respectively. The concordance rate between cytology and bile ctDNA analyses was 87.5%. CONCLUSIONS: Mutated tumor DNA could be detected in bile by NGS. Liquid biopsy of bile might help us to diagnose GBCa because of higher sensitivity and positive predict value compared to cytology with ERCP. PMID- 29580154 TI - Inhibitory Gi/O-coupled receptors in somatosensory neurons: Potential therapeutic targets for novel analgesics. AB - Primary sensory neurons in the dorsal root ganglia and trigeminal ganglia are responsible for sensing mechanical and thermal stimuli, as well as detecting tissue damage. These neurons express ion channels that respond to thermal, mechanical, or chemical cues, conduct action potentials, and mediate transmitter release. These neurons also express a large number of G-protein coupled receptors, which are major transducers for extracellular signaling molecules, and their activation usually modulates the primary transduction pathways. Receptors that couple to phospholipase C via heterotrimeric Gq/11 proteins and those that activate adenylate cyclase via Gs are considered excitatory; they positively regulate somatosensory transduction and they play roles in inflammatory sensitization and pain, and in some cases also in inducing itch. On the other hand, receptors that couple to Gi/o proteins, such as opioid or GABAB receptors, are generally inhibitory. Their activation counteracts the effect of Gs stimulation by inhibiting adenylate cyclase, as well as exerts effects on ion channels, usually resulting in decreased excitability. This review will summarize knowledge on Gi-coupled receptors in sensory neurons, focusing on their roles in ion channel regulation and discuss their potential as targets for analgesic and antipruritic medications. PMID- 29580157 TI - Spontaneous response to and expressive regulation of mirth elicited by humorous cartoons in younger and older adults. AB - Many studies have examined the effect of aging on the ability to regulate negative emotions but less is known about the way the elderly people control their positive affects. Thirty-eight younger and 38 older adults were compared on their affective, expressive, physiological, and behavioral spontaneous responses to and in expressive regulation of mirth elicited by humorous cartoons. Compared to younger adults, older adults were equally amused and aroused but showed lower expressivity in their spontaneous reaction. They were similarly successful in implementing expressive regulation but they had lower physiological activation under amplification condition and more gaze avoidance from the key areas of the cartoons under suppression condition. This indicates that in older, amplification skills are disjointed from the physiological responses and suppression skills seem supplanted by a less costly strategy of attention redeployment. This also suggests that older adults' behavior is not driven by a greater preference for positive information. PMID- 29580158 TI - Quantifying beetle-macrofungal associations in a temperate biodiversity hot spot. AB - Beetles (Coleoptera) are often among the most abundant and diverse insects that feed on sporocarps of macrofungi, but little is known regarding their relative specialism or generalism in most communities. We surveyed >9000 sporocarps in montane hardwood forest in the Appalachian Mountains (USA) to characterize associations of mycophagous beetles and macrofungi. We used traditional metrics and network analyses to quantify relationships between sporocarp traits (mass, age, persistence, and toughness) and assemblages of adult beetles, drawing from >50 000 beetles collected over two survey years. Strict-sense specificity was rare in these associations: most beetle species were found on multiple fungal genera, and most fungi hosted multiple beetle species. Sporocarp age and fresh mass were positively associated with beetle diversity in fungi with ephemeral sporocarps (here including 12 genera of Agaricales and Russulales), but sporocarp persistence was not. In Polyporales, beetle diversity was greater in softer sporocarps than in tough or woody sporocarps. The increase of beetle diversity in aging sporocarps could not be attributed to increases in sporocarp mass or sampling point in the growing season, suggesting that age-related changes in chemistry or structure may support increasingly diverse beetle communities. Interaction networks differed as a function of sporocarp age, revealing that community-wide measures of generalism (i.e., network connectance) and evenness (i.e., variance in normalized degree) change as sporocarps mature and senesce. Beetles observed on Agaricales and Russulales with more persistent sporocarps had narrower interaction breadth (i.e., were more host-specific) than those on less persistent sporocarps, and beetles on Polyporales with tougher sporocarps had narrower interaction breadth than those on soft sporocarps. In addition to providing a large-scale evaluation of sporocarp use by adult beetles in this temperate biodiversity hot spot, this study shows that characteristics of food organisms are associated with specialism and generalism in interactions relevant to fungal and forest ecology. PMID- 29580159 TI - A systematic review and meta-analysis of the effects of educating parents on the benefits and schedules of childhood vaccinations in low and middle-income countries. AB - Public health benefits of childhood vaccinations risk being derailed by low vaccination coverage in low and middle-income countries. One reason for the low coverage is poor parental knowledge of the importance of completing vaccination schedules. We therefore assessed the effects on childhood vaccination coverage, of educating parents and other persons assuming the parental role. We prospectively registered the systematic review, published the protocol, and used standard Cochrane methods to collect and synthesise the evidence. We found six eligible randomised trials with 4248 participants. Three trials assessed health facility based education of mothers on the importance of completing vaccination schedules; immediately after birth and three months later (one study) or during the first vaccination visit (two studies). The other trials assessed community based education, including information campaigns on the importance of vaccines using audiotaped presentations and leaflet distributions (one study); structured group discussions on benefits and costs of childhood vaccination and local action plans for improving vaccine uptake (one study); and home-based information sessions using graphic cards showing benefits and costs of childhood vaccinations and location of vaccination centres (one study). Combining the data shows that these interventions lead to substantial improvements in childhood vaccination coverage (relative increase 36%, 95% confidence interval 14% to 62%). There was no difference between the effects of community-based and facility-based education. Therefore, education in communities and health facilities on the importance of childhood vaccinations should be integrated into all vaccination programmes in low and middle-income countries; accompanied by robust monitoring of impacts and use of data for action. PMID- 29580160 TI - Significant transcriptome and cytokine changes in hepatitis B vaccine non responders revealed by genome-wide comparative analysis. AB - Individuals fail to elicit protective antibody after hepatitis B vaccination remain at risk for hepatitis B virus infection. Analysis of the transcriptome of peripheral blood mononuclear cells (PBMCs) is essential to elucidate the characteristics of gene expression in non-responders. In this study, we enrolled seven responders who had received three injections and seven non-responders who had six injections of hepatitis B vaccine before. All the participants were then vaccinated with a three-dose boost regimen. Microarray analysis and Luminex assay were applied to examine mRNA expression and Th1/Th2/Th9/Th17/Th22/Treg cytokine and chemokine profiles in non-responders and responders. Differentially expressed genes in PBMCs of non-responders at 5 time points, i.e. pre-vaccination, 3rd, 7th, 28th day post the first dose vaccination and 7th day post the second dose vaccination indicated a dense network trend. Compared with responders, nine coding genes (BPI, DEFA1B, DEFA4, CEACAM8, MMP8, FOLR3, LTF, TCN1 and TKTL1) were significantly up-regulated in non-responders at all 5 time points, which could probably be the characteristic genes in hepatitis B vaccine non-responsiveness. Gene ontology analysis revealed that most of the DEGs were related with immune responses. Validation results of these 9 genes using quantitative real-time polymerase chain reaction were mostly consistent with the results of microarray. Cytokine analysis demonstrated that IL-27 and CXCL12 concentrations in responders were significantly higher than non-responders on the 3rd day after the first dose and 7th day after the second dose of vaccination, respectively. No significant difference was observed in other cytokine and chemokine signatures between the two groups. In conclusion, our results revealed characteristic transcriptome and cytokine changes in hepatitis B vaccine non-responders after boost immunization. PMID- 29580161 TI - Comparison of EpCAMhighCD44+ cancer stem cells with EpCAMhighCD44- tumor cells in colon cancer by single-cell sequencing. AB - Cancer stem cells (CSCs) are considered to be responsible for tumorigenesis and cancer relapse. EpCAMhighCD44+ tumor cells are putative colorectal CSCs that express high levels of stem cell genes, while the EpCAMhighCD44- population mostly contains differentiated tumor cells (DTCs). This study aims to determine whether single CSC (EpCAMhighCD44+) and DTC (EpCAMhighCD44-) can be distinguished in terms of somatic copy number alterations (SCNAs). We applied fluorescence activated cell sorting to isolate the CD45-EpCAMhighCD44+ and CD45-EpCAMhighCD44- populations from two primary colon tumors, on which low-coverage single-cell whole-genome sequencing (WGS) was then performed ~0.1x depth. We compared the SCNAs of the CSCs and DTCs at single-cell resolution. In total, 47 qualified single cells of the two populations underwent WGS. The single-cell SCNA profiles showed that there were obvious SCNAs in both the CSCs and DTCs of each patient, and each patient had a specific copy number alteration pattern. Hierarchical clustering and correlation analysis both showed that the SCNA profiles of CSCs and DTCs from the same patient had similar SCNA pattern, while there were regional differences in the CSCs and DTCs in certain patient. SCNAs of CSCs in the same patient were highly reproducible. Our data suggest that major SCNAs occurred at an early stage and were inherited steadily. The similarity of ubiquitous SCNAs between the CSCs and DTCs might have arisen from lineage differentiation. CSCs from the same patient had reproducible SCNA profiles, indicating that gain or loss in certain chromosome is required for colon cancer development. PMID- 29580162 TI - Updates in pancreatic cancer: Modest gains and hopeful targets. AB - Pancreatic cancer is the twelfth most common cancer in the United States, representing 3.2% of all new cancer cases. While composing a small percentage of cancer diagnoses, pancreatic cancer is amongst the most lethal carcinomas, with an overall 5-year survival of 8.2% and incidence rates almost equivocal to death rates. By the time of diagnosis, a majority of patients will present with advanced stage disease. For patients with resectable disease, the estimated overall survival (OS) remains low at 20% as most will develop metastatic disease within 5 years. The lethality of this cancer is attributed to several factors including delayed presentation, lack of effective screening, and complex tumor biology and genetics. Data also suggest that even upon early presentation, pancreatic cancer is a systemic disease with micrometastasis present in the early stages. Traditional cytotoxic therapies have not been clinically impactful in pancreatic cancer, especially in advanced stages, and very little headway has been made in the development of new targeted therapies. As such, this review will discuss current advances in standard of care treatments and novel drug targets being researched. PMID- 29580163 TI - From Homer and Hippocrates to modern personalized medicine: is there a role for pharmacoepigenomics in the treatment of alcohol addiction? AB - From the earliest times to the present, alcohol has evolved as part of life and culture. For most adults, moderate alcohol use is harmless, however, it lies at one end of a range that moves through alcohol abuse to alcohol addiction. Alcohol addiction is a serious and chronic psychiatric disorder that, on top of its heavy consequences on health, also brings significant social and economic losses to individuals and society at large. Pharmacotherapy of alcohol addiction exists, but its effectiveness varies significantly among individuals. Genomic and nongenomic factors are significant contributors to interindividual variation in the clinical presentation of alcohol problems and the response to a given treatment. In addition, emerging evidence suggests pharmacoepigenomics of alcohol addiction as a novel promising area for improvement of alcohol addiction management. PMID- 29580164 TI - Emergence of KRAS-mutation in liver metastases after an anti-EGFR treatment in patient with colorectal cancer: Are we aware of the therapeutic impact of intratumor heterogeneity? AB - Tumors represent a dynamic system where the genomic plasticity permits to adapt to the perturbation induced by environmental pressures, supporting the importance of longitudinal tumor sampling strategies to deciphering the temporal acquisition of driver event that could impact treatment outcome. We describe the case of a metastatic colorectal cancer (mCRC) patient, RAS wild-type, who responded to anti EGFR therapy and underwent liver surgery, revealing a KRAS mutations in the metastatic lesion, not detectable prior to initiation of therapy in the colonic biopsy. After liver surgery, the patient received chemotherapy alone, then underwent left colectomy and the final pathological report confirmed the KRAS wild-type status. We can speculate the existence of two distinct populations of KRAS wild-type and mutant CRC cells sharing the same genetic origin. The anti EGFR treatment represented a selective pressure which allowed the selection of KRAS mutant subclones. The prognostic and /or predictive role of intratumor heterogeneity has not been assessed prospectively. Our case report is of clinical relevance because patients with mCRC who respond to anti-EGFR antibodies often develop resistance within several months of initiating therapy, thus outlining the importance to better ascertain the molecular landscape of tumors to design better therapeutic strategies. PMID- 29580165 TI - Accelerometer and GPS Analysis of Trail Use and Associations With Physical Activity. AB - BACKGROUND: Concurrent use of accelerometers and global positioning system (GPS) data can be used to quantify physical activity (PA) occurring on trails. This study examined associations of trail use with PA and sedentary behavior (SB) and quantified on trail PA using a combination of accelerometer and GPS data. METHODS: Adults (N = 142) wore accelerometer and GPS units for 1-4 days. Trail use was defined as a minimum of 2 consecutive minutes occurring on a trail, based on GPS data. We examined associations between trail use and PA and SB. On trail minutes of light-intensity, moderate-intensity, and vigorous-intensity PA, and SB were quantified in 2 ways, using accelerometer counts only and with a combination of GPS speed and accelerometer data. RESULTS: Trail use was positively associated with total PA, moderate-intensity PA, and light-intensity PA (P < .05). On trail vigorous-intensity PA minutes were 346% higher when classified with the combination versus accelerometer only. Light-intensity PA, moderate-intensity PA, and SB minutes were 15%, 91%, and 85% lower with the combination, respectively. CONCLUSIONS: Adult trail users accumulated more PA on trail use days than on nontrail use days, indicating the importance of these facilities for supporting regular PA. The combination of GPS and accelerometer data for quantifying on trail activity may be more accurate than accelerometer data alone and is useful for classifying intensity of activities such as bicycling. PMID- 29580166 TI - Anaesthetic effects of alfaxalone administered intraperitoneally alone or combined with dexmedetomidine and fentanyl in the rat. AB - Alfaxalone is a neuroactive steroid used as a general anaesthetic in several species including dogs, cats, rabbits and ferrets. It has a wide margin of safety and a similar anaesthetic profile to propofol. To increase its aqueous solubility, a new formulation with cyclodextrins has been marketed recently. The objective of this study was to evaluate the anaesthetic effect of several doses of alfaxalone alone, considering differences between sexes, and alfaxalone combined with dexmedetomidine and fentanyl in the rat administered by the intraperitoneal route. A total of 40 Sprague Dawley rats, involved in three studies, were used. Firstly, 25, 35 and 45 mg kg-1 of alfaxalone alone were tested. In a second study, alfaxalone (25 mg kg-1, females; 75 mg kg-1, males) was combined with dexmedetomidine (0.05 mg kg-1). Finally, alfaxalone (20 mg kg 1, females; 60 mg kg-1, males) was combined with dexmedetomidine (0.05 mg kg-1) and fentanyl (0.1 mg kg-1). Times of onset and duration of anaesthesia, and analgesia, deemed as losing of withdrawal pedal reflex, were recorded. Alfaxalone alone produced a 2 - to 3-fold longer time of anaesthesia in females, although surgical anaesthesia was not achieved in either sex. The addition of dexmedetomidine and fentanyl to alfaxalone produced a similar time of analgesia as well as increased time of anaesthesia in both sexes. In conclusion, alfaxalone produces light anaesthesia in rats, and males required a higher dose. The combination with other sedatives or analgesics, such as dexmedetomidine or fentanyl, allows a more prolonged anaesthesia with analgesic effects, potentially suitable for invasive procedures. PMID- 29580167 TI - Evaluation of heat stress and heat strain among employees working outdoors in an extremely hot environment. AB - A heat stress evaluation was conducted among employees engaged in strenuous work in an extremely hot outdoor environment. Environmental conditions that contribute to heat stress along with various physiological indicators of heat strain were monitored on a task-basis for nine employees daily across four workdays. Employees performed moderate to heavy tasks in elevated environmental conditions for longer periods of time than recommended by various heat stress exposure limits. Seven of nine employees showed evidence of excessive heat strain according to criteria yet all employees were able to self-regulate task duration and intensity to avoid heat-related illness. PMID- 29580169 TI - Integration of membrane separation and Fenton processes for sanitary landfill leachate treatment. AB - The appropriate treatment of sanitary landfill leachate is one of the greatest challenges nowadays due to the large volumes of solid waste generated. Thus, the aim of this study is to evaluate the performance of different routes involving the integration of advanced oxidation processes based on Fenton's reagents (AOP Fenton) and microfiltration (MF) and nanofiltration (NF) membrane processes for the treatment of landfill leachate. MF module configuration (submerged or sidestream) and MF and NF recovery rate were evaluated. The combination of AOP Fenton, MF and NF proved to be an effective treatment for landfill leachate. High removal efficiencies of chemical oxidation demand (94-96%) and colour (96-99%) were obtained. The configuration named route 3, composed of MF of raw landfill leachate (MF1), POA-Fenton-MF2 of the MF1 concentrate and NF of both MF1 and MF2 permeates, showed a higher global water recovery and was responsible for lower waste generation. It was considered the best one in terms of environmental, technical and economical aspects. PMID- 29580170 TI - Comparison of Therapeutic Triiodothyronine Versus Metoprolol in the Treatment of Myocardial Infarction in Rats. AB - BACKGROUND: Beta blockers are standard therapy for myocardial infarction (MI). Preclinical studies have shown efficacy and safety of thyroid hormone (TH) treatment of cardiovascular disorders. Since THs interact with the sympathoadrenergic system, this study aimed to compare triiodothyronine (T3) and metoprolol (Met) in the treatment of rats with MI on pathophysiology and TH adrenergic signaling. METHODS: Female Sprague-Dawley rats aged 12 weeks underwent left anterior descending coronary artery ligation (MI) or sham surgeries. T3 (5 MUg/kg/day) or Met (100 mg/kg/day) was given in drinking water immediately after surgery for eight weeks. At the terminal of the experiments, the rats were subjected to morphological, functional, and molecular examination. RESULTS: T3 and Met significantly enhanced left ventricular contractility (left ventricular fractional shortening 21.37 +/- 2.58% and 21.14 +/- 3.71%, respectively) compared to untreated MI (17.88 +/- 1.23%), and decreased the incidence of inducible atrial tachyarrhythmia by 87.5% and 62.5%, respectively. Although both treatments showed efficacy, T3 but not Met showed statistically significant improvements compared to MI in arrhythmia duration, left atrial diameter (T3 vs. MI 4.33 +/- 0.63 vs. 5.65 +/- 1.32 mm; p < 0.05), fibrosis (6.1 +/- 0.6%, 6.6 +/- 0.6% vs. 8.2 +/- 0.7%, T3, Met vs. MI, respectively), and aortic vasorelaxation responsiveness to acetylcholine (pD2 6.97 +/- 0.22, 6.83 +/- 0.21 vs. 6.66 +/- 0.22, T3, Met vs. MI, respectively). Quantitative polymerase chain reaction showed that T3 and Met attenuated expression of genes associated with inflammation and oxidative stress and restored expression of ion channels and contractile proteins. CONCLUSION: These results support comparable efficacy of T3 and Met treatments, suggesting that T3 may provide a therapeutic alternative to standard beta-receptor blockade, especially for patients intolerant to treatment with beta-blockers after MI. PMID- 29580171 TI - MRI for Fetal Developmental Brain Abnormalities: Perspectives From the Pregnant Patient. AB - Ultrasound is routinely used as a prenatal screening and diagnostic tool but has limitations. Some anomalies in the developing fetal brain can be difficult to detect, and in utero magnetic resonance imaging (iuMRI) is increasingly used as an adjunct to ultrasound. However, understandings of patient perspectives of iuMRI technology are still developing. Our qualitative study of 41 mothers who experienced iuMRI was embedded in a diagnostic accuracy trial and aimed to inform policy recommendations that might stem from the clinical findings. Our analysis suggests that iuMRI is seen as useful, offering valuable additional information and helping women make decisions about care options at a difficult time. However, patients' experiences demonstrated the uncertainty and anxiety associated with the prenatal diagnosis (PND) process relating to brain anomalies including the challenges of their embodied contributions. Our findings suggest more could be done to reduce the impact on pregnant women during an already difficult, anxious period. PMID- 29580168 TI - Photocrosslinkable Gelatin/Tropoelastin Hydrogel Adhesives for Peripheral Nerve Repair. AB - Suturing peripheral nerve transections is the predominant therapeutic strategy for nerve repair. However, the use of sutures leads to scar tissue formation, hinders nerve regeneration, and prevents functional recovery. Fibrin-based adhesives have been widely used for nerve reconstruction, but their limited adhesive and mechanical strength and inability to promote nerve regeneration hamper their utility as a stand-alone intervention. To overcome these challenges, we engineered composite hydrogels that are neurosupportive and possess strong tissue adhesion. These composites were synthesized by photocrosslinking two naturally derived polymers, gelatin-methacryloyl (GelMA) and methacryloyl substituted tropoelastin (MeTro). The engineered materials exhibited tunable mechanical properties by varying the GelMA/MeTro ratio. In addition, GelMA/MeTro hydrogels exhibited 15-fold higher adhesive strength to nerve tissue ex vivo compared to fibrin control. Furthermore, the composites were shown to support Schwann cell (SC) viability and proliferation, as well as neurite extension and glial cell participation in vitro, which are essential cellular components for nerve regeneration. Finally, subcutaneously implanted GelMA/MeTro hydrogels exhibited slower degradation in vivo compared with pure GelMA, indicating its potential to support the growth of slowly regenerating nerves. Thus, GelMA/MeTro composites may be used as clinically relevant biomaterials to regenerate nerves and reduce the need for microsurgical suturing during nerve reconstruction. PMID- 29580172 TI - Paw preferences in the Asian small-clawed otter - using an inexpensive, video based protocol to study laterality of rare species in the zoo. AB - It is still debated whether limb-use preferences represent a common trait in vertebrates, which is based on a shared phylogenetic history. Unravelling the evolutionary origin and pattern of paw preferences in vertebrates requires the analysis of a larger number of species within an ecologically relevant setting. We therefore investigated whether observations in a zoo enable the collection of reliable data sets by quantifying paw use in two independent groups of Asian small-clawed otters (Amblonyx cinerea). Employing a continuous focal animal sampling method, each day one of the ten individuals was video recorded from outside of the enclosure during usual activity. We selected four types of unimanual behaviour (reaching for food, reaching for non-food, reaching into a hole, carrying an object) and quantified paw use for each animal. Our study provides first evidences for individual paw preferences in otters, which were in line with previously reported forelimb use pattern in carnivoran species. Preferences differed between motor acts but for "reaching into a hole" a population-level right paw bias was detected. These data support that observations in a zoological setting are useful to explore task-dependent paw preferences and may facilitate future studies investigating paw preferences under experimentally controlled conditions. PMID- 29580173 TI - Reinforced Electrospun Polycaprolactone Nanofibers for Tracheal Repair in an In Vivo Ovine Model. AB - Tracheal stenosis caused by congenital anomalies, tumors, trauma, or intubation related damage can cause severe breathing issues, diminishing the quality of life, and potentially becoming fatal. Current treatment methods include laryngotracheal reconstruction or slide tracheoplasty. Laryngotracheal reconstruction utilizes rib cartilage harvested from the patient, requiring a second surgical site. Slide tracheoplasty involves a complex surgical procedure to splay open the trachea and reconnect both segments to widen the lumen. A clear need exists for new and innovative approaches that can be easily adopted by surgeons, and to avoid harvesting autologous tissue from the patient. This study evaluated the use of an electrospun patch, consisting of randomly layered polycaprolactone (PCL) nanofibers enveloping 3D-printed PCL rings, to create a mechanically robust, suturable, air-tight, and bioresorbable graft for the treatment of tracheal defects. The study design incorporated two distinct uses of PCL: electrospun fibers to promote tissue integration, while remaining air-tight when wet, and 3D-printed rings to hold the airway open and provide external support and protection during the healing process. Electrospun, reinforced tracheal patches were evaluated in an ovine model, in which all sheep survived for 10 weeks, although an overgrowth of fibrous tissue surrounding the patch was observed to significantly narrow the airway. Minimal tissue integration of the surrounding tissue and the electrospun fibers suggested the need for further improvement. Potential areas for further improvement include a faster degradation rate, agents to increase cellular adhesion, and/or an antibacterial coating to reduce the initial bacterial load. PMID- 29580174 TI - Effect of hydrochlorothiazide on serum uric acid concentration: a genome-wide association study. AB - AIM: To recognize genetic associations of hydrochlorothiazide-induced change in serum uric acid (SUA) concentration. PATIENTS & METHODS: We conducted a genome wide association study on hydrochlorothiazide-induced change in SUA in 214 Finnish men from the GENRES study. Replication analyses were performed in 465 Finns from the LIFE study. RESULTS: In GENRES, we identified 31 loci associated with hydrochlorothiazide-induced change in SUA at p < 5 * 10-5. rs1002976 near VEGFC associated with the change in GENRES and in LIFE. rs950569 near BRINP3 associated with the change in SUA in GENRES and LIFE. The analysis of previously reported SNPs and candidate genes provided some proof for PADI4 and ABCC4. CONCLUSION: We report genetic markers that may predict the increase in SUA concentration during thiazide treatment. PMID- 29580175 TI - The Usage of Digital Resources by Swedish Suicide Bereaved in Their Grief Work: A Survey Study. AB - This study examined Swedish suicide bereaved individuals' use of different resources in their grief work and how they value these resources. The material consisted of a web-based survey, which was analyzed with quantitative methods. The results showed that the psychosocial ill-health was severe among the suicide bereaved participants and that a majority used digital resources in their grief work. The propensity to engage in online support groups or memorial websites was not predicted by the severity of psychosocial consequences following the suicide. However, multiple regressions showed that higher online support group activity predicted more satisfaction with current psychosocial health, while memorial websites seemed to have the opposite effect. This study not only indicates that some digital resources, for example, online support groups, may be an effective way of coping with grief related to suicide loss, but also suggests that memorial websites may increase rumination and in this way cause emotional distress. PMID- 29580176 TI - Reliability and Validity of Tethered Swimming Lactate Minimum Test and Their Relationship With Performance in Young Swimmers. AB - PURPOSE: To test the reliability and validity of tethered swimming lactate minimum test in young swimmers. METHODS: Lactate minimum test was performed twice to test the reliability (experiment 1; n = 13). In addition, the validity was investigated through lactate minimum test relationships with tethered swimming lactate threshold and peak force obtained during graded exercise test (experiment 2; n = 11). Finally, the correlations with mean speeds observed during 200-m (s200m) and 30-minute continuous efforts (s30min) were also analyzed (experiment 3; n = 15). In all experiments, the lactate minimum test began with 3-minute all out effort to induce lactatemia, followed by an exhaustive graded exercise test. RESULTS: The lactate minimum intensity and mean force during the entire 3-minute all-out effort (MF) showed high reliability (coefficient of variation < 8.9% and intraclass correlation coefficient > .93). The lactate minimum intensity was not different compared with lactate threshold (P = .22), presenting high correlations (r = .92) and agreement (95% limits of agreement = +/-7.9 N). The mean force during the entire 3-minute all-out effort was similar to peak force obtained during graded exercise test (P = .41), presenting significant correlations (r = .88) and high indices of agreement (95% limits of agreement = +/-11.3 N). In addition, lactate minimum test parameters correlated both with mean speeds observed during 200-m (r > .74) and 30-minute continuous efforts (r > .70). CONCLUSION: Thus, tethered swimming lactate minimum test can be used for training recommendations and to monitor aerobic adaptations in young swimmers. PMID- 29580177 TI - Sensor-triggered sampling to determine instantaneous airborne vapor exposure concentrations. AB - It is difficult to measure transient airborne exposure peaks by means of integrated sampling for organic chemical vapors, even with very short-duration sampling. Selection of an appropriate time to measure an exposure peak through integrated sampling is problematic, and short-duration time-weighted average (TWA) values obtained with integrated sampling are not likely to accurately determine actual peak concentrations attained when concentrations fluctuate rapidly. Laboratory analysis for integrated exposure samples is preferred from a certainty standpoint over results derived in the field from a sensor, as a sensor user typically must overcome specificity issues and a number of potential interfering factors to obtain similarly reliable data. However, sensors are currently needed to measure intra-exposure period concentration variations (i.e., exposure peaks). In this article, the digitized signal from a photoionization detector (PID) sensor triggered collection of whole-air samples when toluene or trichloroethylene vapors attained pre-determined levels in a laboratory atmosphere generation system. Analysis by gas chromatography-mass spectrometry of whole-air samples (with both 37 and 80% relative humidity) collected using the triggering mechanism with rapidly increasing vapor concentrations showed good agreement with the triggering set point values. Whole-air samples (80% relative humidity) in canisters demonstrated acceptable 17-day storage recoveries, and acceptable precision and bias were obtained. The ability to determine exceedance of a ceiling or peak exposure standard by laboratory analysis of an instantaneously collected sample, and to simultaneously provide a calibration point to verify the correct operation of a sensor was demonstrated. This latter detail may increase the confidence in reliability of sensor data obtained across an entire exposure period. PMID- 29580178 TI - Combining NSAM and CPC concentrations to determine airborne nanoparticle count median diameter: Application to various laboratory and workplace aerosols. AB - Because nanomaterials have been increasingly developed and used in many technology and industry sectors over the last 20 years, an increasing number of workers is likely to be exposed to airborne nanoparticles. In addition, the question of the nanomaterial characteristics that should be assessed in epidemiological studies remains open. Thus, assessing occupational exposure to airborne nanoparticles will not only rely on mass concentration and chemical composition. Rather, key parameters, such as particle size, have to be included in measurement strategies. We previously proposed a methodology to estimate the Count Median Diameter (CMD) of an aerosol based on the simultaneous size integrated measurement of two particle concentrations, lung-deposited surface area, and number, thanks to field-portable, commercially available aerosol instruments (Nanoparticle Surface Area Monitor/Condensation Particle Counter combination). In addition to previous work, this study investigates the case of various polydisperse metal oxides, organic oil, and salt particles with CMDs ranging from 16-410 nm. Once corrected, the CMDs derived from the NSAM/CPC agree within +/-20% with regard to the reference electrical mobility equivalent diameter, regardless of aerosol composition, morphology, or geometric standard deviation (GSD). Furthermore, the field-applicability of the method was tested through 6 sets of experimental data stemming from workplace measurement campaigns where different materials were produced and handled (TiO2, SiO2, Ag, Multi-Walled Carbon Nanotubes-MWCNT), covering a range of CMDs between 40 and 190 nm. All situations considered, the approach based on the combination of a NSAM and a CPC leads to a satisfying estimation of particle CMD, within +/-20% compared to reference CMD.

PMID- 29580181 TI - Decellularized Cartilage Directs Chondrogenic Differentiation: Creation of a Fracture Callus Mimetic. AB - Complications that arise from impaired fracture healing have considerable socioeconomic implications. Current research in the field of bone tissue engineering predominantly aims to mimic the mature bone tissue microenvironment. This approach, however, may produce implants that are intrinsically unresponsive to the cues present during the initiation of fracture repair. As such, this study describes the development of decellularized xenogeneic hyaline cartilage matrix in an attempt to mimic the initial reparative phase of fracture repair. Three approaches based on vacuum-assisted osmotic shock (Vac-OS), Triton X-100 (Vac STx), and sodium dodecyl sulfate (Vac-SDS) were investigated. The Vac-OS methodology reduced DNA content below 50 ng/mg of tissue, while retaining 85% of the sulfate glycosaminoglycan content, and as such was selected as the optimal methodology for decellularization. The resultant Vac-OS scaffolds (decellularized extracellular matrix [dcECM]) were also devoid of the immunogenic alpha-Gal epitope. Furthermore, minimal disruption to the structural integrity of the dcECM was demonstrated using differential scanning calorimetry and fluorescence lifetime imaging microscopy. The biological integrity of the dcECM was confirmed by its ability to drive the chondrogenic commitment and differentiation of human chondrocytes and periosteum-derived cells, respectively. Furthermore, histological examination of dcECM constructs implanted in immunocompetent mice revealed a predominantly M2 macrophage-driven regenerative response both at 2 and 8 weeks postimplantation. These findings contrasted with the implanted native costal cartilage that elicited a predominantly M1 macrophage-mediated inflammatory response. This study highlights the capacity of dcECM from the Vac OS methodology to direct the key biological processes of endochondral ossification, thus potentially recapitulating the callus phase of fracture repair. PMID- 29580182 TI - Perceived importance and difficulty of online activities among visually impaired persons in Nigeria. AB - This study investigated perceived relevance of and difficulties in access to day to-day online activities among visually impaired computer users who used screen readers. The 98 participants in the study were grouped into visually impaired adults (aged 20-59, n = 60) and visually impaired older adults (aged 60 and over, n = 38). Data were collected in structured interview questionnaires with Likert scales exploring ratings of perceived importance and difficulty of access to 11 online platforms of various internet activities. Analyses revealed that the two groups did not differ significantly in ratings of perceived importance of four major online activities, namely sending or reading email (p = 0.5224), online banking (p = 0.2833), online shopping (p = 0.1829), and health information seeking (p = 0.1414). The topmost rated activity of priority among both groups was sending and reading emails. Findings also show that, apart from sending and reading emails, activities rated as important were mostly perceived as difficult to access. The implications of the study for inclusive design and strategies and/or interventions to encourage uptake of internet use among the visually impaired population are discussed. PMID- 29580183 TI - 13th International Workshop on Resistance to Thyroid Hormone and Thyroid Hormone Action. PMID- 29580184 TI - Launching the dialogue: Safety and innovation as partners for success in advanced manufacturing. AB - Emerging and novel technologies, materials, and information integrated into increasingly automated and networked manufacturing processes or into traditional manufacturing settings are enhancing the efficiency and productivity of manufacturing. Globally, there is a move toward a new era in manufacturing that is characterized by: (1) the ability to create and deliver more complex designs of products; (2) the creation and use of materials with new properties that meet a design need; (3) the employment of new technologies, such as additive and digital techniques that improve on conventional manufacturing processes; and (4) a compression of the time from initial design concept to the creation of a final product. Globally, this movement has many names, but "advanced manufacturing" has become the shorthand for this complex integration of material and technology elements that enable new ways to manufacture existing products, as well as new products emerging from new technologies and new design methods. As the breadth of activities associated with advanced manufacturing suggests, there is no single advanced manufacturing industry. Instead, aspects of advanced manufacturing can be identified across a diverse set of business sectors that use manufacturing technologies, ranging from the semiconductors and electronics to the automotive and pharmaceutical industries. The breadth and diversity of advanced manufacturing may change the occupational and environmental risk profile, challenge the basic elements of comprehensive health and safety (material, process, worker, environment, product, and general public health and safety), and provide an opportunity for development and dissemination of occupational and environmental health and safety (OEHS) guidance and best practices. It is unknown how much the risk profile of different elements of OEHS will change, thus requiring an evolution of health and safety practices. These changes may be accomplished most effectively through multi-disciplinary, multi-sector, public private dialogue that identifies issues and offers solutions. PMID- 29580185 TI - Assessing occupational erionite and respirable crystalline silica exposure among outdoor workers in Wyoming, South Dakota, and Montana. AB - Erionite is a naturally occurring fibrous mineral found in many parts of the world, including the western United States. Inhalational exposure to erionite fibers in some localities is associated with health effects similar to those caused by asbestos exposure, including malignant mesothelioma. Therefore, there is concern regarding occupational exposures in the western United States. Currently, there are no standard sampling and analytical methods for airborne erionite fibers, as well as no established occupational exposure limits. Due to the potential adverse health effects, characterizing and minimizing exposures is prudent. Crystalline silica also occurs naturally in areas where erionite is found, principally as the mineral quartz. Work activities involving rocks containing quartz and soils derived from those rocks can lead to exposure to respirable crystalline silica (RCS). The typically dry and dusty environment of the western United States can increase the likelihood of exposures to aerosolized rocks and soils, but inhalation exposure is also possible in more humid conditions. In this case study, we describe several outdoor occupational environments with potential exposures to erionite and RCS. We describe our method for evaluating those exposures and demonstrate: (1) the occurrence of occupational exposures to airborne erionite and RCS, (2) that the chemical make up of the erionite mineral can be determined, and (3) that effective dust control practices are needed to reduce employee exposures to these minerals. PMID- 29580186 TI - Chronic Discrimination and Sleep Problems in Late Life: Religious Involvement as Buffer. AB - The association between chronic discrimination and sleep problems is important to examine in older adults because sleep is highly reactive to stress and impaired sleep has diverse adverse health effects. The association between chronic discrimination and sleep problems may, however, be confounded by a number of time stable influences, and this association may also vary by religious involvement. In three waves (2006, 2010, and 2014) of the Health and Retirement Study ( N = 7,130), the overall association between chronic discrimination and sleep problems is negated in econometric models that control for all time-stable sources of confounding. Religious involvement does not modify this association for men, but a significant association is found among women who do not attend religious services. These analyses suggest that the association between chronic discrimination and sleep quality in late life is substantially inflated due to unobserved time-stable confounders, although women who do not attend religious services may be at risk. PMID- 29580187 TI - Grandparenting and Self-Rated Health Among Older Korean Women. AB - An increasing number of older Korean women have played an important role in taking care of their grandchildren to help their adult children. This study investigates the effects of grandparenting on older women' health in South Korea. Using the Korean Longitudinal Study of Aging ( N = 3,092), we estimated ordinal logistic regression models with lagged dependent variable to examine whether and how grandparenting type and transition and grandparenting intensity are associated with older women's self-rated health. Results show that grandmothers who provide long-term nonresidential grandparenting have better self-rated health than grandmothers who are not engaged in grandparenting. Grandmothers caring for grandchildren in skipped-generation households or multigenerational households do not suffer from a deficit in health. Grandparenting intensity is not associated with grandmothers' health. Our findings suggest that the implications of grandparenting for older women's health may differ in different social and cultural contexts. PMID- 29580188 TI - Ovarian cancer-derived extracellular vesicles affect normal human fibroblast behavior. AB - It has become clear that non-tumor cells in the microenvironment, especially fibroblasts, actively participate in tumor progression. Fibroblasts conditioned by tumor cells become "activated" and, as such, are identified as CAFs (cancer associated fibroblasts). These CAFs remodel the tumor stroma to make it more favourable for cancer progression. The aim of this work was to verify whether EVs (extracellular vesicles - whose role as mediators of information between tumor and stromal cells is well known) released from human ovarian cancer cells were able to activate fibroblasts. EVs isolated from SKOV3 (more aggressive) and CABA I (less aggressive) cells were administered to fibroblasts. The consequent activation was supported by morphological and molecular changes in treated fibroblasts; XTT assays, zymographies, wound healing tests and invasion assays also highlighted higher proliferation, motility, invasiveness and enzyme expression. The secretome of these "activated" fibroblasts was, in turn, able to modulate the responses (proliferation, motility and invasion) of fibroblasts, and of tumor and endothelial cells. These findings support the idea that ovarian cancer cells can modulate fibroblast behaviour through the release of EVs, activating them to a CAFs-like state; the latter are able, in turn, to stimulate the surrounding cells. EVs from SKOV3 rather than from CABA I seem to be more efficient in some processes. PMID- 29580189 TI - Occupational exposure monitoring data collection, storage, and use among state based and private workers' compensation insurers. AB - Despite substantial financial and personnel resources being devoted to occupational exposure monitoring (OEM) by employers, workers' compensation insurers, and other organizations, the United States (U.S.) lacks comprehensive occupational exposure databases to use for research and surveillance activities. OEM data are necessary for determining the levels of workers' exposures; compliance with regulations; developing control measures; establishing worker exposure profiles; and improving preventive and responsive exposure surveillance and policy efforts. Workers' compensation insurers as a group may have particular potential for understanding exposures in various industries, especially among small employers. This is the first study to determine how selected state-based and private workers' compensation insurers collect, store, and use OEM data related specifically to air and noise sampling. Of 50 insurers contacted to participate in this study, 28 completed an online survey. All of the responding private and the majority of state-based insurers offered industrial hygiene (IH) services to policyholders and employed 1 to 3 certified industrial hygienists on average. Many, but not all, insurers used standardized forms for data collection, but the data were not commonly stored in centralized databases. Data were most often used to provide recommendations for improvement to policyholders. Although not representative of all insurers, the survey was completed by insurers that cover a substantial number of employers and workers. The 20 participating state based insurers on average provided 48% of the workers' compensation insurance benefits in their respective states or provinces. These results provide insight into potential next steps for improving the access to and usability of existing data as well as ways researchers can help organizations improve data collection strategies. This effort represents an opportunity for collaboration among insurers, researchers, and others that can help insurers and employers while advancing the exposure assessment field in the U.S. PMID- 29580190 TI - Sami yoik, Sami history, Sami health: a narrative review. AB - Music as a possible health-promoting agent has attained increasing academic and scientific interest over the last decades. Nonetheless, possible connections between indigenous singing traditions and health beyond traditional ceremonial healing practices are still under-researched worldwide. The Sami, the indigenous people living in Northern Fennoscandia, have a distinct ancient vocal music tradition called "yoik" practiced from immemorial times. The Sami share a history of assimilation with many indigenous people. During this period of nearly 400 years, yoik alongside other cultural markers was under hard pressure and even banned at times. Compared to other indigenous people in the Arctic, Sami public health shows few significant unfavourable differences to the majority population. The potential role of yoik as a protective health and resilience factor within the Sami culture is the topic of this review. We suggest a two stage model for the health promoting effects of yoik through i) emotion regulation and stress relief on the level of the individual, and ii) as a socio-cultural resilience factors within the Sami population. This review is to be understood as theory building review article striving for a scholarly review of the literature. PMID- 29580192 TI - Potential Uses of Vinegar as a Medicine and Related in vivo Mechanisms. AB - While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria. PMID- 29580193 TI - Releasability of asbestos fibers from weathered roof cement. AB - Chrysotile asbestos fibers were added to roofing products, including roof cement, for several decades. The fibers were described as "encapsulated" and therefore incapable of being released, an assertion that is disproved by the study reported herein. Three test panels of roof cement from the original container were exposed to ambient weathering in 2015 and 2016. Two panels were then sampled using the ASTM D5755 microvacuum method. Sampling revealed a light brown sub-layer under the dark brown surface layer, both of which crumbled and became friable during sampling. Analysis of the microvacuum samples with transmission electron microscopy showed that the material on the 2 panels contained 4,432,000 and 3,320,000 asbestos structures per cm2 with nearly all of the structures consisting of fibers less than 5 um long. Energy dispersive spectrometry determined that none of the fibers reported were coated with asphalt. The presence of free fibers was confirmed by direct examination of the surfaces of the panels and of dust released from handling the panels via scanning electron microscopy. This study confirmed the releasability of uncoated asbestos fibers from dried roof cement that was indicated in 2 previous studies published in 2007 and 2010. These results suggest that the finding of the Fifth Circuit Court in 1997 that uncoated airborne asbestos fibers cannot be released from roof cement, and therefore do not present a potential exposure by inhalation, was erroneous in retrospect. The exemption of roof cement from regulation under the Occupational Safety and Health Administration Construction Industry Standard for asbestos by the Court should not be relied on by employers of workers who remove weathered asbestos-containing roof cement, and precautions should be taken against exposure to airborne asbestos fibers during this work. PMID- 29580194 TI - Post-licensure safety surveillance of zoster vaccine live (Zostavax(r)) in the United States, Vaccine Adverse Event Reporting System (VAERS), 2006-2015. AB - BACKGROUND: Herpes zoster (HZ), or shingles, is caused by reactivation of varicella-zoster virus in latently infected individuals. Live-attenuated HZ vaccine (zoster vaccine live, ZVL) is approved in the United States for persons aged >=50 years and recommended by the CDC for persons >=60 years. METHODS: We analyzed U.S. reports of adverse events (AEs) following ZVL submitted to the Vaccine Adverse Event Reporting System (VAERS), a spontaneous reporting system to monitor vaccine safety, for persons vaccinated May 1, 2006, through January 31, 2015. We conducted descriptive analysis, clinical reviews of reports with selected pre-specified conditions, and empirical Bayesian data mining. RESULTS: VAERS received 23,092 reports following ZVL, of which 22,120 (96%) were classified as non-serious. Of reports where age was documented (n = 18,817), 83% were in persons aged >=60 years. Reporting rates of AEs were 106 and 4.4 per 100,000 ZVL doses distributed for all reports and serious reports, respectively. When ZVL was administered alone among persons aged >=50 years, injection site erythema (27%), HZ (17%), injection site swelling (17%), and rash (14%) were the most commonly reported symptoms among non-serious reports; HZ (29%), pain (18%), and rash (16%) were the most commonly reported symptoms among serious reports. Six reports included laboratory evidence of vaccine-strain varicella-zoster virus (Oka/Merck strain) infection; AEs included HZ, HZ- or varicella-like illness, and local reaction with vesicles. In our review of reports of death with sufficient information to determine cause (n = 46, median age 75 years), the most common causes were heart disease (n = 28), sepsis (n = 4), and stroke (n = 3). Empirical Bayesian data mining did not detect new or unexpected safety signals. CONCLUSIONS: Findings from our safety review of ZVL are consistent with those from pre-licensure clinical trials and other post-licensure assessments. Transient injection-site reactions, HZ, and rashes were most frequently reported to VAERS following ZVL. Overall, our results are reassuring regarding the safety of ZVL. PMID- 29580195 TI - Sex Differences in the Association Between Gaming and Serious Violence Among Predominantly African American Youth. AB - Video gaming, a remarkably popular hobby in the United States, has been consistently identified as a correlate of aggressive behavior, and this association is not limited to violent video gaming. Prior studies of sex differences in the association between video gaming and aggression have not controlled for other well-known violence correlates (e.g., substance use, community violence exposure, violence attitudes) or focused primarily on high risk youth. In this study, we used data from an emergency department in Flint, Michigan ( N = 409, 59.9% female, 93.4% African American) to identify sex differences in the association between video gaming and serious peer violence. Youth aged 14 to 20 years were recruited from October 2011 to March 2015, and self-administered computerized surveys including measures of demographics, violence perpetration, gaming frequency, substance use, community violence exposure, and violence attitudes. The primary outcome was an indicator of any serious violence perpetration (e.g., choking, burning, weapon violence) in the past 2 months. Using logistic regression, we estimated the association between gaming and serious violence perpetration, and how it varied by sex, while controlling for demographics, substance use, community violence exposure, and violence attitudes. Approximately 36.6% of males and 27.3% of females reported past 2-month serious violence. On adjusted analysis, hours spent gaming was associated with violence among females (odds ratio [OR] = 1.40, 95% confidence interval [CI] = [1.16, 1.78]), but not males (OR = 1.03, 95% CI = [0.89, 1.19]); in the model including both males and females, the interaction between hours gaming and sex was significant ( p < .01). Our findings suggest video gaming is a stronger marker of severe violence perpetration in females than males among at risk youth. Violence interventions among females may be improved by including content related to video gaming and identifying other prosocial activities for youth as an alternative to video gaming. Additional research is required to clarify the causal process underlying the identified associations, and to determine what aspects of video gaming are risk-enhancing.

AB - Family violence is threatening behavior carried out by a person to coerce or control another member of the family or causes the family member to be fearful. Health practitioners are well placed to play a pivotal role in identifying and responding to family violence; however, their perceived capacity to respond to patients experiencing family violence is not well understood. We aim to explore Australian health practitioners' current perspectives, practices, and perceived barriers in working with family violence, including perceived confidence in responding effectively to cases of family violence encountered during their work with patients. A total of 1,707 health practitioners primarily practicing in the wider Melbourne region were identified, and 114 health practitioners participated in the study between March 2016 and August 2016 by completing an investigator developed questionnaire. Descriptive, qualitative, and thematic analyses were performed. The majority of participants recognized family violence to be a health issue and that family violence would impact the mental health of afflicted persons. Despite this, only a fifth of participants felt they were very confident in screening, supporting, and referring patients with family violence experiences. Perceived barriers to inquire about family violence included time constraints and greater importance placed on screening for other health issues. Health practitioners reported that additional training on screening, supporting, and referring patients would be beneficial. Australian health practitioners need to be upskilled. Recently, in Australia, state-relevant toolkits have been developed to provide succinct information about responding to initial patient presentations of family violence, how to inquire about family violence, and how to handle disclosures (and nondisclosures) by patients. Further resources could be developed to aid health practitioners in providing assistance to their patients as indicated. These initiatives would be a step toward addressing the concerns with regard to the lack of training and could possibly optimize outcomes for patients experiencing family violence.

AB - Commercial sexual exploitation of children (CSEC) is a social problem in the United States that has recently received growing attention from policy makers, advocates, and researchers. Despite increasing awareness of this issue, information on the prevalence, demographic profile, and psychosocial needs of victims of CSEC is scarce. To better understand the scope of CSEC and to examine the feasibility of screening for CSEC in Child Advocacy Centers (CACs), a pilot study was initiated through Arkansas Building Effective Services for Trauma (ARBEST) to identify youth who may be at risk for commercial sexual exploitation. Data for this pilot study were collected from all of the state's CACs ( n = 14) over a 6-month period. Family advocates completed a screening questionnaire adapted from Greenbaum, Dodd, and McCracken with 918 youth aged 12 to 18 years old treated at CACs. Almost 20% of youth were identified as being at high risk for experiencing CSEC. Furthermore, youth classified as high-risk for commercial sexual exploitation reported significantly more avoidance symptoms on the UCLA (University of California at Los Angeles) PTSD (Posttraumatic Stress Disorder) Reaction Index than youth classified as low-risk. The results suggest that a significant portion of youth treated at CACs in Arkansas are at high risk for experiencing commercial sexual exploitation, which may be associated with a particular pattern of trauma symptoms. These findings also lend support for the feasibility and utilization of a screening questionnaire as part of routine care in CACs to potentially identify youth at risk for CSEC. PMID- 29580198 TI - Pharmacogenetics of oral antidiabetic therapy. AB - Type 2 diabetes prevalence is still on the rise worldwide. Antidiabetic drugs are widely prescribed to patients with Type 2 diabetes. Most patients start with metformin which is mostly well tolerated. However, a high percentage of patients fail to achieve glycemic control. The effectiveness of metformin as well as most other antidiabetic drugs depends among other factors on interindividual genetic differences that are up to now ignored in the treatment of Type 2 diabetes. Interestingly, many genes influencing the effectiveness of antidiabetic drugs are Type 2 diabetes risk genes making matters worse. Here, we shed light on these interindividual genetic differences. PMID- 29580199 TI - Screening of Pig (Sus scrofa) Bactericidal Permeability-Increasing Protein (BPI) Gene as Marker for Disease Resistance. AB - Salmonella infection can cause septicemia, acute or chronic enteritis and wasting in weaned pigs, but may occur in other age groups. The bactericidal/permeability increasing protein (BPI) gene plays an important role in the natural defense of the host and is found to be associated with resistance/susceptibility to Salmonella infection and identified as a candidate gene for disease resistance breeding in pig. This study was conducted to screen the resistance and/or susceptibility of pigs to Salmonella infection, to determine the genotype and evaluate presence of resistant allele of the BPI gene in population of pigs, and to establish genetic data for pig breeders for the improvement of Philippine pig industry. In this study, 389 blood samples from different pig breeds were collected from pig breeder farms in the Philippines. Genomic DNA was extracted from these samples and genotyping was done by PCR-RFLP analysis using AvaII restriction enzyme. Out of 389 pigs, the genotypic frequency showed that 98.4, 1.3, and 0.3% pigs are resistant (GG), heterozygous type (AG), and susceptible (AA), respectively. The application of BPI gene as marker for disease resistance will provide information to the pig industry to implement strategies for the identification of Salmonella infection-resistant pigs. PMID- 29580200 TI - Evaluating the effect of training along with fit testing on earmuff users in a Chinese textile factory. AB - A hearing protection fit testing was conducted on workers (n = 189) in a textile factory in southern China. The 3M E-A-Rfit Dual-Ear Validation System was used to measure the personal attenuation rating (PAR) on an over-the-head style earmuff at the work site. In addition, PARs were obtained several times throughout the same work shift to capture different fits on 39 workers. Follow-up visits were conducted in approximate 6-month or 12-month intervals to repeat the fit testing. Both the immediate and residual effects of training on the field attenuation of hearing protection devices obtained by workers, and the effects of training toward improving the attenuation and protection of earmuffs after a period of daily use, were observed. A questionnaire survey was used to assess the awareness of hearing health and motivation toward the use of earmuffs in a high temperature environment. The results showed that there were wide variations in PARs among the workers tested. The one-on-one training together with fit testing improved PAR and helped to reduce the negative impact caused by use of protective hair covers. Since earmuffs are often used for long periods of time (>1 year), repeating fit tests could be helpful in order to verify the attenuation received throughout their useful life. PMID- 29580201 TI - Combining six genome scan methods to detect candidate genes to salinity in the Mediterranean striped red mullet (Mullus surmuletus). AB - BACKGROUND: Adaptive genomics may help predicting how a species will respond to future environmental changes. Genomic signatures of local adaptation in marine organisms are often driven by environmental selective agents impacting the physiology of organisms. With one of the highest salinity level, the Mediterranean Sea provides an excellent model to investigate adaptive genomic divergence underlying salinity adaptation. In the present study, we combined six genome scan methods to detect potential genomic signal of selection in the striped red mullet (Mullus surmuletus) populations distributed across a wide salinity gradient. We then blasted these outlier sequences on published fish genomic resources in order to identify relevant potential candidate genes for salinity adaptation in this species. RESULTS: Altogether, the six genome scan methods found 173 outliers out of 1153 SNPs. Using a blast approach, we discovered four candidate SNPs belonging to three genes potentially implicated in adaptation of M. surmuletus to salinity. The allele frequency at one of these SNPs significantly increases with salinity independently from the effect of longitude. The gene associated to this SNP, SOCS2, encodes for an inhibitor of cytokine and has previously been shown to be expressed under osmotic pressure in other marine organisms. Additionally, our results showed that genome scan methods not correcting for spatial structure can still be an efficient strategy to detect potential footprints of selection, when the spatial and environmental variation are confounded, and then, correcting for spatial structure in a second step represents a conservative method. CONCLUSION: The present outcomes bring evidences of potential genomic footprint of selection, which suggest an adaptive response of M. surmuletus to salinity conditions in the Mediterranean Sea. Additional genomic data such as sequencing of a full-genome and transcriptome analyses of gene expression would provide new insights regarding the possibility that some striped red mullet populations are locally adapted to their saline environment. PMID- 29580203 TI - Sample size determination for mediation analysis of longitudinal data. AB - BACKGROUND: Sample size planning for longitudinal data is crucial when designing mediation studies because sufficient statistical power is not only required in grant applications and peer-reviewed publications, but is essential to reliable research results. However, sample size determination is not straightforward for mediation analysis of longitudinal design. METHODS: To facilitate planning the sample size for longitudinal mediation studies with a multilevel mediation model, this article provides the sample size required to achieve 80% power by simulations under various sizes of the mediation effect, within-subject correlations and numbers of repeated measures. The sample size calculation is based on three commonly used mediation tests: Sobel's method, distribution of product method and the bootstrap method. RESULTS: Among the three methods of testing the mediation effects, Sobel's method required the largest sample size to achieve 80% power. Bootstrapping and the distribution of the product method performed similarly and were more powerful than Sobel's method, as reflected by the relatively smaller sample sizes. For all three methods, the sample size required to achieve 80% power depended on the value of the ICC (i.e., within subject correlation). A larger value of ICC typically required a larger sample size to achieve 80% power. Simulation results also illustrated the advantage of the longitudinal study design. The sample size tables for most encountered scenarios in practice have also been published for convenient use. CONCLUSIONS: Extensive simulations study showed that the distribution of the product method and bootstrapping method have superior performance to the Sobel's method, but the product method was recommended to use in practice in terms of less computation time load compared to the bootstrapping method. A R package has been developed for the product method of sample size determination in mediation longitudinal study design. PMID- 29580202 TI - Carcinoembryonic antigen as a marker of radioresistance in colorectal cancer: a potential role of macrophages. AB - BACKGROUND: We sought to identify the carcinoembryonic antigen (CEA) as a marker of radioresistance in rectal cancer. METHODS: From July 1997 to January 2008, 104 patients with stage II or III rectal cancer who were treated with post-operative radiotherapy (PORT) were included in this study. The doses of radiotherapy ranged from 45 to 54.6 Gy. The CEA levels were measured before surgery. We analyzed the actuarial rates of overall survival (OS), distant metastasis (DM), and local recurrence (LR) using Kaplan-Meier curves. Multivariate analyses were performed with Cox regression models. We used THP-1 monocyte cell lines for macrophage differentiation (M0, M1 or M2). The RNA extracted from the macrophages was analyzed via a genomic method in the core laboratory. The radiosensitivities of CEA-rich LS1034 cells were compared between cells with and without the conditioned media from CEA-stimulated macrophages. RESULTS: Preoperative CEA levels >=10 ng/mL were independent predictive factors for OS (p = 0.005), DM (p = 0.026), and LR (p = 0.004). The OS rates among the patients with pretreatment CEA levels < 10 ng/mL and >=10 ng/mL were 64.5% and 35.9% (p = 0.004), respectively. The corresponding rates of DM were 40.6% and 73.1% (p = 0.024). The corresponding rates of LR were 6.6% and 33.9% (p = 0.002). In the M0 macrophages, exogenous CEA elicited a dose-response relationship with M2 differentiation. In the CEA stimulated M0 cells, some mRNAs were upregulated by as much as 5-fold, including MMP12, GDF15, and JAG1. In the CEA-stimulated M2 cells, a 4-fold up-regulation of GADD45G mRNA was noted. The conditioned media from the CEA-stimulated M2 cells elicited an increase in the numbers of LS180, SW620, and LS1034 cells after irradiation. CEA caused the M2 differentiation of the macrophages. CONCLUSION: Pretreatment CEA levels >=10 ng/mL are a significant risk factor for OS, DM, and LR following PORT for rectal cancer. CEA causes radioresistance in the presence of M2 macrophages. More comprehensive examinations prior to surgery and intensive adjuvant therapy are suggested for patients with CEA levels >=10 ng/mL. Further studies of these mechanisms are needed. PMID- 29580204 TI - Anti-EGFR targeted therapy delivered before versus during radiotherapy in locoregionally advanced nasopharyngeal carcinoma: a big-data, intelligence platform-based analysis. AB - BACKGROUND: Little is known about the prognostic difference of anti-EGFR therapy, cetuximab (CTX) or nimotuzumab (NTZ), concurrently with induction chemotherapy (IC, investigational arm) or RT (control arm) for patients with locoregionally advanced nasopharyngeal carcinoma (LA-NPC). We conducted this retrospective study to address this. METHODS: We identified 296 patients with newly diagnosed LA-NPC at Sun Yat-Sen University Cancer Center between January 2012 and May 2015. Patients were treated by IC with CCRT or RT and CTX/NTZ was delivered during IC or radiotherapy. Survival outcomes and toxicities between different arms were compared. RESULTS: In total, there were 149 patients in the investigational arm and 147 in control arm. The 3-year disease-free survival, overall survival, distant metastasis-free survival and locoregional relapse-free survival rates for investigational arm vs. control arm were 84.3% vs. 74.3% (P = 0.027), 94.0% vs. 92.1% (P = 0.673), 88.0% vs. 81.8% (P = 0.147) and 93.3% vs. 88.0% (P = 0.093). Multivariate analysis revealed patients in the control arm achieved significantly worse disease-free survival (HR, 1.497; 95% CI, 1.016-2.206; P = 0.026) compared with those in the investigational arm; however, no significant difference was identified for other endpoints. Patients in the investigational arm experienced more grade 3-4 skin reaction (15.4% vs. 2.0%, P < 0.001) and mucositis (10.1% vs. 3.4%, P = 0.022) during induction phase, but less skin reaction (5.4% vs. 25.9%, P < 0.001) and mucositis (24.8% vs. 36.7%, P = 0.026) during RT. CONCLUSIONS: Our findings suggested that CTX/NTZ concurrently with IC may be a more effective and promising strategy for patients with LA-NPC receiving intensity-modulated radiotherapy. PMID- 29580207 TI - The effect of Kenya's free maternal health care policy on the utilization of health facility delivery services and maternal and neonatal mortality in public health facilities. AB - BACKGROUND: Kenya abolished delivery fees in all public health facilities through a presidential directive effective on June 1, 2013 with an aim of promoting health facility delivery service utilization and reducing pregnancy-related mortality in the country. This paper aims to provide a brief overview of this policy's effect on health facility delivery service utilization and maternal mortality ratio and neonatal mortality rate in Kenyan public health facilities. METHODS: A time series analysis was conducted on health facility delivery services utilization, maternal and neonatal mortality 2 years before and after the policy intervention in 77 health facilities across 14 counties in Kenya. RESULTS: A statistically significant increase in the number of facility-based deliveries was identified with no significant changes in the ratio of maternal mortality and the rate of neonatal mortality. CONCLUSION: The findings suggest that cost is a deterrent to health facility delivery service utilization in Kenya and thus free delivery services are an important strategy to promote utilization of health facility delivery services; however, there is a need to simultaneously address other factors that contribute to pregnancy-related and neonatal deaths. PMID- 29580205 TI - Primordial origin and diversification of plasmids in Lyme disease agent bacteria. AB - BACKGROUND: With approximately one-third of their genomes consisting of linear and circular plasmids, the Lyme disease agent cluster of species has the most complex genomes among known bacteria. We report here a comparative analysis of plasmids in eleven Borreliella (also known as Borrelia burgdorferi sensu lato) species. RESULTS: We sequenced the complete genomes of two B. afzelii, two B. garinii, and individual B. spielmanii, B. bissettiae, B. valaisiana and B. finlandensis isolates. These individual isolates carry between seven and sixteen plasmids, and together harbor 99 plasmids. We report here a comparative analysis of these plasmids, along with 70 additional Borreliella plasmids available in the public sequence databases. We identify only one new putative plasmid compatibility type (the 30th) among these 169 plasmid sequences, suggesting that all or nearly all such types have now been discovered. We find that the linear plasmids in the non-B. burgdorferi species have undergone the same kinds of apparently random, chaotic rearrangements mediated by non-homologous recombination that we previously discovered in B. burgdorferi. These rearrangements occurred independently in the different species lineages, and they, along with an expanded chromosomal phylogeny reported here, allow the identification of several whole plasmid transfer events among these species. Phylogenetic analyses of the plasmid partition genes show that a majority of the plasmid compatibility types arose early, most likely before separation of the Lyme agent Borreliella and relapsing fever Borrelia clades, and this, with occasional cross species plasmid transfers, has resulted in few if any species specific or geographic region-specific Borreliella plasmid types. CONCLUSIONS: The primordial origin and persistent maintenance of the Borreliella plasmid types support their functional indispensability as well as evolutionary roles in facilitating genome diversity. The improved resolution of Borreliella plasmid phylogeny based on conserved partition-gene clusters will lead to better determination of gene orthology which is essential for prediction of biological function, and it will provide a basis for inferring detailed evolutionary mechanisms of Borreliella genomic variability including homologous gene and plasmid exchanges as well as non-homologous rearrangements. PMID- 29580206 TI - Correlates of evolutionary rates in the murine sperm proteome. AB - BACKGROUND: Protein-coding genes expressed in sperm evolve at different rates. To gain deeper insight into the factors underlying this heterogeneity we examined the relative importance of a diverse set of previously described rate correlates in determining the evolution of murine sperm proteins. RESULTS: Using partial rank correlations we detected several major rate indicators: Phyletic gene age, numbers of protein-protein interactions, and survival essentiality emerged as particularly important rate correlates in murine sperm proteins. Tissue specificity, numbers of paralogs, and untranslated region lengths also correlate significantly with sperm genes' evolutionary rates, albeit to a lesser extent. Multifunctionality, coding sequence or average intron lengths, and mean expression level have insignificant or virtually no independent effects on evolutionary rates in murine sperm genes. Gene ontology enrichment analyses of three equally sized murine sperm protein groups classified based on their evolutionary rates indicate strongest sperm-specific functional specialization in the most quickly evolving gene class. CONCLUSIONS: We propose a model according to which slowly evolving murine sperm proteins tend to be constrained by factors such as survival essentiality, network connectivity, and/or broad expression. In contrast, evolutionary change may arise especially in less constrained sperm proteins, which might, moreover, be prone to specialize to reproduction-related functions. Our results should be taken into account in future studies on rate variations of reproductive genes. PMID- 29580208 TI - Screening for inhibitors of mutacin synthesis in Streptococcus mutans using fluorescent reporter strains. AB - BACKGROUND: Within the polymicrobial dental plaque biofilm, bacteria kill competitors by excreting mixtures of bacteriocins, resulting in improved fitness and survival. Inhibiting their bacteriocin synthesis might therefore be a useful strategy to eliminate specific pathogens. We used Streptococcus mutans, a highly acidogenic inhabitant of dental plaque, as a model and searched for natural products that reduced mutacin synthesis. To this end we fused the promoter of mutacin VI to the GFP+ gene and integrated the construct into the genome of S. mutans UA159 by single homologous recombination. RESULTS: The resulting reporter strain 423p - gfp + was used to screen 297 secondary metabolites from different sources, mainly myxobacteria and fungi, for their ability to reduce the fluorescence of the fully induced reporter strain by > 50% while growth was almost unaffected (> 90% of control). Seven compounds with different chemical structures and different modes of action were identified. Erinacine C was subsequently validated and shown to inhibit transcription of all three mutacins of S. mutans. The areas of the inhibition zones of the sensor strains S. sanguinis and Lactococcus lactis were reduced by 35% to 61% in comparison to controls in the presence of erinacine C, demonstrating that the amount of active mutacins in the culture supernatants of S. mutans was reduced. Erinacines are cyathane diterpenes that were extracted from cultures of the edible mushroom Hericium erinaceus. They have anti-inflammatory, antimicrobial and neuroprotective effects. For erinacine C, a new biological activity was found here. CONCLUSIONS: We demonstrate the successful development of a whole-cell fluorescent reporter for the screening of natural compounds and report that erinacine C suppresses mutacin synthesis in S. mutans without affecting cell viability. PMID- 29580209 TI - Physical activity and fitness are associated with verbal memory, quality of life and depression among nursing home residents: preliminary data of a randomized controlled trial. AB - BACKGROUND: Few studies have simultaneously examined changes in physical, cognitive and emotional performance throughout the aging process. METHODS: Baseline data from an ongoing experimental randomized study were analyzed. Physical activity, handgrip, the Senior Fitness Test, Trail Making Test A, Rey Auditory-Verbal Learning Test, Quality of Life-Alzheimer's Disease Scale (QoL-AD) and the Goldberg Depression Scale were used to assess study participants. Logistic regression models were applied. TRIAL REGISTRATION: ACTRN12616001044415 (04/08/2016). RESULTS: The study enrolled 114 participants with a mean age of 84.9 (standard deviation 6.9) years from ten different nursing homes. After adjusting for age, gender and education level, upper limb muscle strength was found to be associated with Rey Auditory-Verbal Learning Test [EXP(B): 1.16, 95% confidence interval (CI): 1.04-1.30] and QoL-AD [EXP(B): 1.18, 95% CI: 1.06 1.31]. Similarly, the number of steps taken per day was negatively associated with the risk of depression according to the Goldberg Depression Scale [EXP(B): 1.14, 95% CI: 1.000-1.003]. Additional analyses suggest that the factors associated with these variables are different according to the need for using an assistive device for walking. In those participants who used it, upper limb muscle strength remained associated with Rey Auditory-Verbal Learning Test [EXP(B): 1.21, 95% CI: 1.01-1.44] and QoL-AD tests [EXP(B): 1.19, 95% CI: 1.02 1.40]. In those individuals who did not need an assistive device for walking, lower limb muscle strength was associated with Rey Auditory-Verbal Learning Test [EXP(B): 1.35, 95% CI: 1.07-1.69], time spent in light physical activity was associated with QoL-AD test [EXP(B): 1.13, 95% CI: 1.00-1.02], and the number of steps walked per day was negatively associated with the risk of depression according to the Goldberg Depression Scale [EXP(B): 1.27, 95% CI: 1.000-1.004]. CONCLUSIONS: Muscle strength and physical activity are factors positively associated with a better performance on the Rey Auditory-Verbal Learning Test, QoL-AD and Goldberg Depression Scale in older adults with mild to moderate cognitive impairment living in nursing homes. These associations appeared to differ according to the use of an assistive device for walking. Our findings support the need for the implementation of interventions directed to increase the strength and physical activity of individuals living in nursing homes to promote physical, cognitive and emotional benefits. TRIAL REGISTRATION: ACTRN12616001044415 (04/08/2016). PMID- 29580210 TI - Defense against territorial intrusion is associated with DNA methylation changes in the honey bee brain. AB - BACKGROUND: Aggression is influenced by individual variation in temperament as well as behavioral plasticity in response to adversity. DNA methylation is stably maintained over time, but also reversible in response to specific environmental conditions, and may thus be a neuromolecular regulator of both of these processes. A previous study reported DNA methylation differences between aggressive Africanized and gentle European honey bees. We investigated whether threat-induced aggression altered DNA methylation profiles in the honey bee brain in response to a behavioral stimulus (aggression-provoking intruder bee or inert control). We sampled five minutes and two hours after stimulus exposure to examine the effect of time on epigenetic profiles of aggression. RESULTS: There were DNA methylation differences between aggressive and control bees for individual cytosine-guanine dinucleotides (CpGs) across the genome. Eighteen individual CpG sites showed significant difference between aggressive and control bees 120 min post stimulus. For clusters of CpGs, we report four genomic regions differentially methylated between aggressive and control bees at the 5-min time point, and 50 regions differentially methylated at the120-minute time point following intruder exposure. Differential methylation occurred at genes involved in neural plasticity, chromatin remodeling and hormone signaling. Additionally, there was a significant overlap of differential methylation with previously published epigenetic differences that distinguish aggressive Africanized and gentle European honey bees, suggesting an evolutionarily conserved use of brain DNA methylation in the regulation of aggression. Lastly, we identified individually statistically suggestive CpGs that as a group were significantly associated with differentially expressed genes underlying aggressive behavior and also co-localize with binding sites of transcription factors involved in neuroplasticity or neurodevelopment. CONCLUSIONS: There were DNA methylation differences in the brain associated with response to an intruder. These differences increased in number a few hours after the initial exposure and overlap with previously reported aggression-associated genes and neurobiologically relevant transcription factor binding sites. Many DNA methylation differences that occurred in association with the expression of aggression in real time also exist between Africanized bees and European bees, suggesting an evolutionarily conserved role for epigenetic regulation in aggressive behavior. PMID- 29580211 TI - New insight into the mechanism underlying the silk gland biological process by knocking out fibroin heavy chain in the silkworm. AB - BACKGROUND: Exploring whether and how mutation of silk protein contributes to subsequent re-allocation of nitrogen, and impacts on the timing of silk gland degradation, is important to understand silk gland biology. Rapid development and wide application of genome editing approach in the silkworm provide us an opportunity to address these issues. RESULTS: Using CRISPR/Cas9 system, we successfully performed genome editing of Bmfib-H. The loss-of-function mutations caused naked pupa and thin cocoon mutant phenotypes. Compared with the wild type, the posterior silk gland of mutant showed obviously degraded into fragments in advance of programmed cell death of silk gland cells. Comparative transcriptomic analyses of silk gland at the fourth day of the fifth instar larval stage(L5D4)identified 1456 differential expressed genes (DEGs) between posterior silk gland (PSG) and mid silk gland (MSG) and 1388 DEGs between the mutant and the wild type. Hierarchical clustering of all the DEGs indicated a remarkable down-regulated and an up-regulated gene clade in the mutant silk glands, respectively. Down-regulated genes were overrepresented in the pathways involved in cancer, DNA replication and cell proliferation. Intriguingly, up-regulated DEGs are significantly enriched in the proteasome. By further comparison on the transcriptome of MSG and PSG between the wild type and the mutant, we consistently observed that up-regulated DEGs in the mutant PSG were enriched in protein degrading activity and proteasome. Meantime, we observed a series of up regulated genes involved in autophagy. Since these protein degradation processes would be normally occur after the spinning time, the results suggesting that these progresses were activated remarkably ahead of schedule in the mutant. CONCLUSIONS: Accumulation of abnormal fib-H protein might arouse the activation of proteasomes as well as autophagy process, to promote the rapid degradation of such abnormal proteins and the silk gland cells. Our study therefore proposes a subsequent process of protein and partial cellular degradation caused by mutation of silk protein, which might be helpful for understanding its impact of the silk gland biological process, and further exploration the re-allocation of nitrogen in the silkworm. PMID- 29580212 TI - Frequency of HPV in oral cavity squamous cell carcinoma. AB - BACKGROUND: The prevalence of high-risk human papillomavirus (HPV) DNA in cases of oral cavity squamous cell carcinoma (SCC) varies widely. The aim of this study is to investigate the frequency of high-risk HPV DNA in a large Brazilian cohort of patients with oral cavity SCC. METHODS: Biopsy and resected frozen and formalin-fixed paraffin-embedded specimens of oral cavity SCC were available from 101 patients who were recruited at two Brazilian centres. Stringent measures with respect to case selection and prevention of sample contamination were adopted to ensure reliability of the data. Nested PCR using MY09/MY11 and GP5+/GP6+ as well as PGMY09/11 L1 consensus primers were performed to investigate the presence of HPV DNA in the tumours. HPV-positive cases were subjected to direct sequencing. Shapiro-Wilk and Student t test were used to evaluate data normality and to compare the means, respectively. Qualitative variables were analysed by logistic regression. RESULTS: Our results demonstrate that the frequency of high-risk HPV types in oral cavity SCC is very low and is less than 4%. All HPV-positive cases were HPV16. In addition, our results do not show a significant association between the tumour clinical features and the risk factors (tobacco, alcohol and HPV) for oral cavity SCC. CONCLUSION: In the current study, we observed an overlapping pattern of risk factors that are related to tumour development. This, along with a low frequency of high-risk HPV DNA, supports the findings that HPV is not involved in the genesis of oral cavity SCC in Brazilian population. PMID- 29580213 TI - Feasibility and acceptability of expressive writing with postpartum women: a randomised controlled trial. AB - BACKGROUND: Pregnancy, birth and adjusting to a new baby is a potentially stressful time that can negatively affect women's mental and physical health. Expressive writing, where people write about a stressful event for at least 15 min on three consecutive days, has been associated with improved health in some groups but it is not clear whether it is feasible and acceptable for use with postpartum women. This study therefore examined the feasibility and acceptability of expressive writing for postpartum women as part of a randomised controlled trial (RCT). METHODS: The Health After Birth Trial (HABiT) was an RCT evaluating expressive writing for postpartum women which included measures of feasibility and acceptability. At 6 to 12 weeks after birth 854 women were randomised to expressive writing, a control writing task or normal care, and outcome measures of health were measured at baseline, one month later and six months later. Feasibility was measured by recruitment, attrition, and adherence to the intervention. Quantitative and qualitative measures of acceptability of the materials and the task were completed six months after the intervention. RESULTS: Recruitment was low (10.7% of those invited to participate) and the recruited sample was from a restricted sociodemographic range. Attrition was high, increased as the study progressed (35.8% at baseline, 57.5% at one month, and 68.1% at six months) and was higher in the writing groups than in the normal care group. Women complied with instructions to write expressively or not, but adherence to the instruction to write for 15 min per day for three days was low (Expressive writing: 29.3%; Control writing: 23.5%). Acceptability measures showed that women who wrote expressively rated the materials/task both more positively and more negatively than those in the control writing group, and qualitative comments revealed that women enjoyed the writing and/or found it helpful even when it was upsetting. CONCLUSIONS: The feasibility of offering expressive writing as a universal self-help intervention to all postpartum women 6 to 12 weeks after birth in the HABiT trial was low, but the expressive writing intervention was acceptable to the majority of women who completed it.

PMID- 29580214 TI - Priming effect of root-applied silicon on the enhancement of induced resistance to the root-knot nematode Meloidogyne graminicola in rice. AB - BACKGROUND: Silicon (Si) can confer plant resistance to both abiotic and biotic stress. In the present study, the priming effect of Si on rice (Oryza sativa cv Nipponbare) against the root-knot nematode Meloidogyne graminicola and its histochemical and molecular impact on plant defense mechanisms were evaluated. RESULTS: Si amendment significantly reduced nematodes in rice roots and delayed their development, while no obvious negative effect on giant cells was observed. Increased resistance in rice was correlated with higher transcript levels of defense-related genes (OsERF1, OsEIN2 and OsACS1) in the ethylene (ET) pathway. Si amendment significantly reduced nematode numbers in rice plants with enhanced ET signaling but had no effect in plants deficient in ET signaling, indicating that the priming effects of Si were dependent on the ET pathway. A higher deposition of callose and accumulation of phenolic compounds were observed in rice roots after nematode attack in Si-amended plants than in the controls. CONCLUSION: These findings indicate that the priming effect may partially depend on the production of phenolic compounds and hydrogen peroxide. Further research is required to model the ethylene signal transduction pathway that occurs in the Si-plant-nematode interaction system and gain a better understanding of Si induced defense in rice. PMID- 29580215 TI - Nomograms predict long-term survival for patients with periampullary adenocarcinoma after pancreatoduodenectomy. AB - BACKGROUND: The prognosis of patients with periampullary adenocarcinoma after pancreatoduodenectomy is diverse and not yet clearly illustrated. The aim of this study was to develop a nomogram to predict individual risk of overall survival (OS) and progression-free survival (PFS) in patients with periampullary adenocarcinoma after pancreatoduodenectomy. METHODS: A total of 205 patients with periampullary adenocarcinoma after pancreatoduodenectomy were retrospectively included. OS and PFS were evaluated by the Kaplan-Meier method. Two nomograms for predicting OS and PFS were established, and the predictive accuracy was measured by the concordance index (Cindex) and calibration plots. RESULTS: Lymph node ratio (LNR), carbohydrate antigen 19-9 (CA19-9) and anatomical location were incorporated into the nomogram for OS prediction and LNR, CA19-9; anatomical location and tumor differentiation were incorporated into the nomogram for PFS prediction. All calibration plots for the probability of OS and PFS fit well. The Cindexes of the nomograms for OS and PFS prediction were 0.678 and 0.68, respectively. The OS and PFS survival times were stratified significantly using the nomogram-predicted survival probabilities. CONCLUSIONS: The present nomograms for OS and PFS prediction can provide valuable information for tailored decision making for patients with periampullary adenocarcinoma after pancreatoduodenectomy. PMID- 29580216 TI - An evaluation of functional mental capacity in forensic mental health practice: the Dundrum capacity ladders validation study. AB - BACKGROUND: Because of the potential gravity of finding a person incompetent, assessment of mental capacity is challenging for clinicians. We aimed to test validity of a new structured professional judgement tool designed to assess functional mental capacity in three domains - finances, welfare and healthcare. METHODS: Fifty-five male forensic psychiatric patients with Schizophrenia were interviewed using the Dundrum Capacity Ladders - a new semi-structured interview, and scores were assigned on a stratified scoring system, measuring ability to understand, reason, appreciate the personal importance of the decision at hand and communicate a decision. Data were also gathered pertaining to level of therapeutic security at the time of interview, diagnosis, neurocognitive function and a validated measure of real world function. RESULTS: The results show that internal consistency and inter-rater reliability were high for all items. There were correlations between higher scores of functional mental capacity, neurocognitive function and measures of real world function in this population. Correlations were in the range 0.358 to 0.693, effect sizes that were moderate to high. CONCLUSIONS: The DUNDRUM Capacity Ladders appear to be a valid measure of functional mental capacity in this population. Further prospective studies of functional mental capacity as a measure of recovery are now required. PMID- 29580218 TI - Education and employment status of adults with autism spectrum disorders in Germany - a cross-sectional-survey. AB - BACKGROUND: Adults with autism spectrum disorders (ASD) experience challenges in participating in the labour market and struggle to achieve and maintain appropriate professional positions, possibly due to impairments of communication and social interaction. Studies have shown high rates of unemployment as well as evidence of inadequate employment. As knowledge on the participation in the German labour market is scarce, the aim of our study was to examine employment status, type of occupation and inadequate employment in a sample of clinically mostly late-diagnosed and most likely not intellectually disabled adults with ASD in Germany. METHODS: We conducted a cross-sectional-survey in clinically mostly late-diagnosed adults with ASD. Employment status, type of occupation, and the level of formal education and training were examined through a postal questionnaire. Inadequate employment regarding participants' current and longest practised occupation was assessed by transforming participants' information into skill levels of the "Classification of Occupations 2010" of the German Federal Employment Agency, and comparing these with participants' level of formal education and training. RESULTS: The response rate was 43.2% (N = 185 of N = 428 potential participants). 94.6% were first-time diagnosed when being 18 years of age or older. 56.8% held a general university entrance-level qualification and 24.9% had obtained a Masters' or diploma degree as their highest vocational qualification. 94.1% had been employed at some time. Of these, 68.4% reported being currently employed, 13.5% being currently unemployed and 17.0% being retired for health reasons. Regarding the longest-practised and the current occupation, the highest proportion of participants was found in the occupational area "health and social sector, teaching and education" (22.4% and 23.3%, respectively). With respect to inadequate employment, 22.1% were found to be overeducated in relation to their longest-practised occupation and 31.3% in relation to their current occupation. This is significantly higher than the percentage of overeducation in the general population. CONCLUSIONS: Despite largely high formal qualifications, the clinically mostly late-diagnosed adults with ASD represented in our sample are disadvantaged regarding their participation in the German labour market, especially with respect to rates of unemployment, early retirement and overeducation. Employment support programs should be developed to improve employment outcomes. PMID- 29580217 TI - Foreign peptide triggers boost in pneumococcal metabolism and growth. AB - BACKGROUND: Nonencapsulated Streptococcus pneumoniae bacteria are successful colonizers of the human nasopharynx and often possess genes aliB-like ORF 1 and 2 in place of capsule genes. AliB-like ORF 2 binds peptide FPPQSV, found in Prevotella species, resulting in enhanced colonization. How this response is mediated is so far unknown. RESULTS: Here we show that the peptide increases expression of genes involved in release of host carbohydrates, carbohydrate uptake and carbohydrate metabolism. In particular, the peptide increased expression of 1,5-anhydro-D-fructose reductase, a metabolic enzyme of an alternative starch and glycogen degrading pathway found in many organisms, in both transcriptomic and proteomic data. The peptide enhanced pneumococcal growth giving a competitive advantage to a strain with aliB-like ORF 2, over its mutant lacking the gene. Possession of aliB-like ORF 2 did not affect release of inflammatory cytokine CXCL8 from epithelial cells in culture and the nonencapsulated wild type strain was not able to establish disease or inflammation in an infant rat model of meningitis. CONCLUSIONS: We propose that AliB-like ORF 2 confers an advantage in colonization by enhancing carbohydrate metabolism resulting in a boost in growth. This may explain the widespread presence of aliB-like ORF 2 in the nonencapsulated pneumococcal population in the human nasopharynx. PMID- 29580219 TI - A Sequel to Sanger: amplicon sequencing that scales. AB - BACKGROUND: Although high-throughput sequencers (HTS) have largely displaced their Sanger counterparts, the short read lengths and high error rates of most platforms constrain their utility for amplicon sequencing. The present study tests the capacity of single molecule, real-time (SMRT) sequencing implemented on the SEQUEL platform to overcome these limitations, employing 658 bp amplicons of the mitochondrial cytochrome c oxidase I gene as a model system. RESULTS: By examining templates from more than 5000 species and 20,000 specimens, the performance of SMRT sequencing was tested with amplicons showing wide variation in GC composition and varied sequence attributes. SMRT and Sanger sequences were very similar, but SMRT sequencing provided more complete coverage, especially for amplicons with homopolymer tracts. Because it can characterize amplicon pools from 10,000 DNA extracts in a single run, the SEQUEL can reduce greatly reduce sequencing costs in comparison to first (Sanger) and second generation platforms (Illumina, Ion). CONCLUSIONS: SMRT analysis generates high-fidelity sequences from amplicons with varying GC content and is resilient to homopolymer tracts. Analytical costs are low, substantially less than those for first or second generation sequencers. When implemented on the SEQUEL platform, SMRT analysis enables massive amplicon characterization because each instrument can recover sequences from more than 5 million DNA extracts a year. PMID- 29580220 TI - Pragmatic RAndomised controlled trial of a trauma-focused guided self-help Programme versus InDividual trauma-focused cognitive Behavioural therapy for post traumatic stress disorder (RAPID): trial protocol. AB - BACKGROUND: There is good evidence that trauma-focused therapies for Post Traumatic Stress Disorder are effective. However, they are not always feasible to deliver due a shortage of trained therapists and demands on the patient. An online trauma-focused Guided Self-Help (GSH) programme which could overcome these barriers has shown promise in a pilot study. This study will be the first to evaluate GSH against standard face-to-face therapy to assess its suitability for use in the NHS. METHODS: The study is a large-scale multi-centre pragmatic randomised controlled non-inferiority trial, with assessors masked to treatment allocation. One hundred and ninety-two participants will be randomly allocated to receive either face-to-face trauma-focused cognitive behaviour therapy (TFCBT) or trauma-focused online guided self-help (GSH). The primary outcome will be the severity of symptoms of PTSD over the previous week as measured by the Clinician Administered PTSD Scale for DSM5 (CAPS-5) at 16 weeks post-randomisation. Secondary outcome measures include PTSD symptoms over the previous month as measured by the CAPS-5 at 52 weeks plus the Impact of Event Scale - revised (IES R), Work and Social Adjustment Scale (WSAS), Patient Health Questionnaire-9 (PHQ 9), General Anxiety Disorder-7 (GAD-7), Alcohol Use Disorders Test (AUDIT-O), Multidimensional Scale for Perceived Social Support (MSPSS), short Post-Traumatic Cognitions Inventory (PTCI), Insomnia Severity Index (ISI) and General Self Efficacy Scale (GSES) measured at 16 and 52 weeks post-randomisation. Changes in health-related quality of life will be measured by the EQ-5D and the level of healthcare resource utilisation for health economic analysis will be determined by an amended version of the Client Socio-Demographic and Service Receipt Inventory European Version. The Client Satisfaction Questionnaire (CSQ) will be collected at 16 weeks post-randomisation to evaluate treatment satisfaction. DISCUSSION: This study will be the first to compare online GSH with usual face-to face therapy for PTSD. The strengths are that it will test a rigorously developed intervention in a real world setting to inform NHS commissioning. The potential challenges of delivering such a pragmatic study may include participant recruitment, retention and adherence, therapist retention, and fidelity of intervention delivery. TRIAL REGISTRATION: ISRCTN13697710 registered on 20/12/2016. PMID- 29580221 TI - Depletion of nuclear import protein karyopherin alpha 7 (KPNA7) induces mitotic defects and deformation of nuclei in cancer cells. AB - BACKGROUND: Nucleocytoplasmic transport is a tightly regulated process carried out by specific transport machinery, the defects of which may lead to a number of diseases including cancer. Karyopherin alpha 7 (KPNA7), the newest member of the karyopherin alpha nuclear importer family, is expressed at a high level during embryogenesis, reduced to very low or absent levels in most adult tissues but re expressed in cancer cells. METHODS: We used siRNA-based knock-down of KPNA7 in cancer cell lines, followed by functional assays (proliferation and cell cycle) and immunofluorescent stainings to determine the role of KPNA7 in regulation of cancer cell growth, proper mitosis and nuclear morphology. RESULTS: In the present study, we show that the silencing of KPNA7 results in a dramatic reduction in pancreatic and breast cancer cell growth, irrespective of the endogenous KPNA7 expression level. This growth inhibition is accompanied by a decrease in the fraction of S-phase cells as well as aberrant number of centrosomes and severe distortion of the mitotic spindles. In addition, KPNA7 depletion leads to reorganization of lamin A/C and B1, the main nuclear lamina proteins, and drastic alterations in nuclear morphology with lobulated and elongated nuclei. CONCLUSIONS: Taken together, our data provide new important evidence on the contribution of KPNA7 to the regulation of cancer cell growth and the maintenance of nuclear envelope environment, and thus deepens our understanding on the impact of nuclear transfer proteins in cancer pathogenesis. PMID- 29580222 TI - Drug-related deaths in Scotland 1979-2013: evidence of a vulnerable cohort of young men living in deprived areas. AB - BACKGROUND: Even after accounting for deprivation, mortality rates are higher in Scotland relative to the rest of Western Europe. Higher mortality from alcohol- and drug-related deaths (DRDs), violence and suicide (particularly in young adults) contribute to this 'excess' mortality. Age-period and cohort effects help explain the trends in alcohol-related deaths and suicide, respectively. This study investigated whether age, period or cohort effects might explain recent trends in DRDs in Scotland and relate to exposure to the changing political context from the 1980s. METHODS: We analysed data on DRDs from 1979 to 2013 by sex and deprivation using shaded contour plots and intrinsic estimator regression modelling to identify and quantify relative age, period and cohort effects. RESULTS: The peak age for DRDs fell around 1990, especially for males as rates increased for those aged 18 to 45 years. There was evidence of a cohort effect, especially among males living in the most deprived areas; those born between 1960 and 1980 had an increased risk of DRD, highest for those born 1970 to 1975. The cohort effect started around a decade earlier in the most deprived areas compared to the rest of the population. CONCLUSION: Age-standardised rates for DRDs among young adults rose during the 1990s in Scotland due to an increased risk of DRD for the cohort born between 1960 and 1980, especially for males living in the most deprived areas. This cohort effect is consistent with the hypothesis that exposure to the changing social, economic and political contexts of the 1980s created a delayed negative health impact. PMID- 29580223 TI - Association between braced curve behavior by pubertal growth peak and bracing effectiveness in female idiopathic scoliosis: a longitudinal cohort study. AB - BACKGROUND: Pre-pubertal idiopathic scoliosis (IS) is associated with high risk of bracing ineffectiveness. Integrated multidimensional maturity assessments are useful but complex to predict the high-risk occurrence of curve progression. This study is designed to provide a simple screening method for brace effectiveness by determining whether or not the braced curve behavior at growth spurt, being defined as variations in Cobb angle velocity (AV) at peak height velocity (PHV), can be a new factor predictive of brace outcome prescribed before PHV. METHODS: This is a retrospective study of a series of 35 IS girls with simplified skeletal maturity score no more than 3 at initiation of bracing treatment and followed up through the growth spurt until brace weaning or surgery. Serial Cobb angle and maturity indicators involving height velocity, Risser sign, triradiate cartilage, simplified skeletal maturity score and distal radius and ulna classification were assessed and patients were stratified into either a positive or negative category based on a positive or negative value of AV at PHV. Comparisons were made between the positive and negative AV groups, as well as the failed and successful bracing groups, using independent sample T test and crosstab analysis. Logistic regression analysis was used to identify the predictive factors of failed brace treatment. RESULTS: Brace treatment prescribed before PHV was found to have an overall failure rate of 57.1% and a surgical rate of 45.7%. Negative AV at PHV accounting for 54.3% of the recruited patients were associated with lower brace failure rate (36.8% vs. 81.2%, p = 0.016) and surgical rate (21.1% vs. 75.0%, p = 0.002). Patients in the failed bracing group showed higher ratio of thoracic curve (80.0% vs. 26.7%,p = 0.002) and higher AV at growth peak (2.3 +/- 9.1 vs. 6.5 +/- 11.4 degrees /yrs., p = 0.016). The logistic regression analysis revealed that positive AV at PHV (OR = 9.268, 95% CI = 1.279-67.137, p = 0.028) and thoracic curve type (OR = 13.391, 95% CI = 2.006-89.412, p = 0.007) were strong predictive factors of ineffective brace treatment initiated before PHV. CONCLUSIONS: Sustained curve correction following bracing despite early onset and rapid pubertal growth was strongly predictive of effective brace control of scoliosis. PMID- 29580225 TI - Psychotropic medication use among patients with celiac disease. AB - BACKGROUND: Celiac disease is a multi-system disorder with manifestations that may result in psychiatric disorders. We assessed the prevalence of medication use to treat psychiatric disorders in celiac disease patients. METHODS: We conducted a cross-sectional study of patients undergoing esophagogastroduodenoscopy over 9 years at a celiac disease referral center. We compared the prevalence of psychotropic medication use among celiac disease patients (n = 1293) to a control group (n = 1401) with abdominal pain or reflux. RESULTS: Among all patients the mean age was 48.4 years, most were female (69.5%), and 22.7% used any psychotropic medication. There was no difference between overall psychotropic medication use among celiac disease patients and controls (23.9% vs 21.8%, OR 1.16; 95% CI 0.96-1.39, p = 0.12). However, those with celiac disease were more likely to use antidepressants on univariate (16.4% vs 13.4%, p = 0.03) and multivariate analysis (OR 1.28; 95% CI 1.03-1.59; p = 0.03). Use of psychotropic medications was not associated with disease duration or mode of presentation of celiac disease. CONCLUSIONS: Celiac disease patients use psychotropic medications at similar rates as those with other gastrointestinal diseases, though subgroup analysis suggests they may use more antidepressants. Future studies should investigate whether celiac disease is associated with mood disorders that are not treated with medications. PMID- 29580224 TI - Intraspecific comparative genomics of isolates of the Norway spruce pathogen (Heterobasidion parviporum) and identification of its potential virulence factors. AB - BACKGROUND: Heterobasidion parviporum is an economically most important fungal forest pathogen in northern Europe, causing root and butt rot disease of Norway spruce (Picea abies (L.) Karst.). The mechanisms underlying the pathogenesis and virulence of this species remain elusive. No reference genome to facilitate functional analysis is available for this species. RESULTS: To better understand the virulence factor at both phenotypic and genomic level, we characterized 15 H. parviporum isolates originating from different locations across Finland for virulence, vegetative growth, sporulation and saprotrophic wood decay. Wood decay capability and latitude of fungal origins exerted interactive effects on their virulence and appeared important for H. parviporum virulence. We sequenced the most virulent isolate, the first full genome sequences of H. parviporum as a reference genome, and re-sequenced the remaining 14 H. parviporum isolates. Genome-wide alignments and intrinsic polymorphism analysis showed that these isolates exhibited overall high genomic similarity with an average of at least 96% nucleotide identity when compared to the reference, yet had remarkable intra specific level of polymorphism with a bias for CpG to TpG mutations. Reads mapping coverage analysis enabled the classification of all predicted genes into five groups and uncovered two genomic regions exclusively present in the reference with putative contribution to its higher virulence. Genes enriched for copy number variations (deletions and duplications) and nucleotide polymorphism were involved in oxidation-reduction processes and encoding domains relevant to transcription factors. Some secreted protein coding genes based on the genome wide selection pressure, or the presence of variants were proposed as potential virulence candidates. CONCLUSION: Our study reported on the first reference genome sequence for this Norway spruce pathogen (H. parviporum). Comparative genomics analysis gave insight into the overall genomic variation among this fungal species and also facilitated the identification of several secreted protein coding genes as putative virulence factors for the further functional analysis. We also analyzed and identified phenotypic traits potentially linked to its virulence. PMID- 29580226 TI - Prevalence of alcohol consumption and alcohol use disorders among outdoor drinkers in public open places in Nigeria. AB - BACKGROUND: There is a rapid shift in the social context of drinking, with a large proportion of regular drinkers favouring outdoor-open space drinking, such as motor-parks, by the road sides, the majority of which are unlicensed premises for drinking. METHOD: This study determined the prevalence and determinants of harmful or hazardous alcohol use and possible dependence, defined as a "likely alcohol use disorder" (AUD) in a community sample of 1119 patrons of open space drinking places in Ibadan, Nigeria, using the AUDIT. Scores of 8 and above signified a likely AUD. The associations between a likely AUD and demographic characteristics were sought using Chi square statistics and binary regression analysis was used to determine the effects of multiple confounding variables on a likely AUD using the SPSS version 20.0 software. RESULTS: Of the entire population, the prevalence of likely AUD was 39.5%, and 44.4% out of the drinking population Multivariate analysis showed that Islamic religion was a negative predictor for likely AUD, OR = 0.13, 95% CI (0.06-0.26), while rural residence, OR = 1.84, 95% CI (1.34-2.53) and cigarette smoking OR = 1.81, 95% CI (1.37-2.40) were predictive of likely AUD. CONCLUSION: Outdoor-open space drinkers are likely to have AUD compared with the general population. Open space drinking has a huge public health implication because of the associated health risks and injuries. PMID- 29580227 TI - First case report of M1 macrophage polarization in an untreated symptomatic patient with toxoplasmosis. AB - BACKGROUND: In immunocompetent patients, acute toxoplasmosis is usually asymptomatic. We identified M1 macrophages in a case of symptomatic acute Toxoplasma gondii infection that resolved without treatment. M1 macrophages have been demonstrated in animal models of toxoplasmosis, but not in humans. CASE PRESENTATION: A 63-year-old woman presented with laterocervical and axillary bilateral lymphadenopathy. Her anamnesis defined an episode of high fever and prolonged asthenia 4 months previously, which suggested an infectious disease. Following laboratory, radiological, and pathological analyses, she was diagnosed with toxoplasmosis. Immunohistochemical analyses were performed on lymph node sections. More than 50% of the macrophages in the lymph node microgranulomas were M1 macrophages, defined by CD68+/p-Stat1+ staining, and the presence of T helper 1 lymphocytes indicated an immune response known to induce M1 macrophage polarization. Activated endothelial cells were found only in inflamed areas. No therapy was administered before or after diagnosis, and the lymphadenopathy resolved after a follow-up of 5 months. CONCLUSIONS: This is the first report to demonstrate the presence of M1 macrophages in human toxoplasmosis. Our findings contribute to the understanding of the pathogenesis of toxoplasmosis, and encourage further studies on the role of macrophage polarization in human toxoplasmosis. PMID- 29580228 TI - Intra- and interobserver reliability of glenoid fracture classifications by Ideberg, Euler and AO. AB - BACKGROUND: Representing 3%-5% of shoulder girdle injuries scapula fractures are rare. Furthermore, approximately 1% of scapula fractures are intraarticularfractures of the glenoid fossa. Because of uncertain fracture morphology and limited experience, the treatment of glenoid fossa fractures is difficult. The glenoid fracture classification by Ideberg (1984) and Euler (1996) is still commonly used in literature. In 2013 a new glenoid fracture classification was introduced by the AO. The purpose of this study was to examine the new AO classification in clinical practice in comparison with the classifications by Ideberg and Euler. METHODS: In total CT images of 84 patients with glenoid fossa fractures from 2005 to 2018 were included. Parasagittal, paracoronary and axial reconstructions were examined according to the classifications of Ideberg, Euler and the AO by 3 investigators (orthopedic surgeon, radiologist, student of medicine) at three individual time settings. Inter- and intraobserver reliability of the three classification systems were ascertained by computing Inter- and Intraclass (ICCs) correlation coefficients using Spearman's rank correlation coefficient, 95%-confidence intervals as well as F-tests for correlation coefficients. RESULTS: Inter- and intraobserver reliability for the AO classification showed a perspicuous coherence (R = 0.74 and R = 0.79). Low to moderate intraobserver reliability for Ideberg (R = 0.46) and Euler classification (R = 0.41) was found. Furthermore, data show a low Interobserver reliability for both Ideberg and Euler classification (R < 0.2). Both the Inter- and Intraclass reliability using AO is significantly higher than those using Ideberg and Euler (p < 0.05). Using the new AO classification, it was possible to find a proper class for every glenoid fossa fracture. On average, according to Euler classification 10 of 84 fractures were not classifiable whereas to Ideberg classification 21 of 84 fractures were not classifiable. CONCLUSION: The new AO classification system introduced 2013 facilitates reliable grading of glenoid fossa fractures with high inter- and intraobserver reliability in 84 patients using CT images. It should possibly be applied in order to enable a valid, reliable and consistent academic description of glenoid fossa fractures. The established classifications by Euler and Ideberg are not capable of providing a similar reliability. PMID- 29580229 TI - Population admixture can enhance establishment success of the introduced biological control agent Cryptolaemus montrouzieri. AB - BACKGROUND: Introduced biological control agents have opportunities of population admixture through multiple introductions in the field. However, the importance of population admixture for their establishment success often remains unclear. Previous studies based on genetic markers have suggested a history of population admixture in the predatory ladybird Cryptolaemus montrouzieri Mulsant in China. RESULTS: We tested whether population admixture may lead to fitness changes under laboratory conditions. We first found no mating barrier or strong bias between two parental populations, despite their differences in genetics and phenotypes. Then, our experimental evidence supported the hypothesis that admixed populations have a higher potential of establishment success, due to their superior reproductive ability, and hunger and cold tolerance inherited from one of the parental populations. CONCLUSIONS: We suggest that population admixture can be a breeding method to improve the performance of biological control agents, particularly when used in a classical biological control approach, but that consequences for potential invasiveness need to be considered. PMID- 29580230 TI - Palliative care for people with schizophrenia: a qualitative study of an under serviced group in need. AB - BACKGROUND: People with schizophrenia are at risk of receiving poorer end of life care than other patients. They are often undertreated, avoid treatment and are about half as likely to access palliative care. There are limited options for end of life care for this under-serviced group in need. This study aims to address the paucity of research by documenting possible need, experiences of health care service use and factors affecting palliative care use for people with schizophrenia who have advanced life limiting illness. METHODS: Semi-structured interviews were undertaken with 16 experienced health professionals caring for people with schizophrenia in Western Australia. The interviews focussed on their perceptions and experiences of end of life care, their patients' unmet needs, palliative care options, and suggested services to support this vulnerable group and improve health care provision. The research used a qualitative design and thematic analyses. RESULTS: The participants all advocated strongly for their patients and recognised their extreme vulnerability. They identified a range of challenges and unmet needs experienced by people with schizophrenia at the end of life including: illness factors such as the impact of schizophrenia on information processing and communication; social factors such as stigma, isolation and the absence of a carer; and health care factors such as late diagnosis, delayed access to care, and mismanagement in care. Four themes were organised into two domains with the first exploring the individual and social circumstances of people with schizophrenia, including the challenges they experience in the health care system. The second domain covers themes that discuss barriers and facilitators to people with schizophrenia receiving palliative care and key features in palliative care provision, including recognising declining health, communication and planning, and collaboration and capacity building in the broader health, mental health and palliative care sectors. CONCLUSIONS: To ensure people with schizophrenia are well supported at the end of life a model of palliative care is required that offers both specialised services and capacity building within the pre-existing health workforce. Resources are needed to address the stigma and lack of services faced by this vulnerable group. PMID- 29580231 TI - GDF15 predict platinum response during first-line chemotherapy and can act as a complementary diagnostic serum biomarker with CA125 in epithelial ovarian cancer. AB - BACKGROUND: Growth differentiation factor 15 (GDF15) has attracted much interest as a novel biomarker for epithelial ovarian carcinoma (EOC). Research focus has been directed at GDF15 as a diagnostic detection, while the prognostic determination of GDF15 in EOC patients remains to be clearly elucidated. The present study aimed to investigate GDF15 level relative to clinicopathological characters, chemoresponse, and clinical outcome of EOC patients. METHODS: Serum from 122 patients with primary diagnosed EOC were analyzed for GDF15 and serum cancer antigen 125 (CA125). All cases were treated with debulking surgery and first-line chemotherapy, and samples were obtained just before debulking surgical treatment and first-line chemotherapy. Subsequently, clinical characteristics, responses to chemotherapy and progression-free survival (PFS) were recorded. RESULTS: Increasing levels of serum GDF15 was significantly associated with FIGO stage and lymphonodus metastasis. GDF15 and CA125 detection are complementary in the diagnosis of EOC and can be simultaneously profiled. The chemo-resistant EOC patients (median, 1225.0 pg/mL) showed significantly higher GDF15 than chemo sensitive patients (median, 824.2 pg/mL; P = 0.013). Highly expressed GDF15 was an independent negative prognostic indicator in the PFS (P = 0.026) of the 122 EOC cases in the multivariate analysis. Additionally, patients with high level of serum CA125 significantly associated with suboptimal (P = 0.043) debulking surgery. CONCLUSIONS: Our results provide valuable evidence that GDF15 is related with first-line chemo-resistance, with highly expressed GDF15 being a strong and an independent indicator of shorter PFS in EOC patients. PMID- 29580232 TI - Mental disorders around cancer diagnosis and increased hospital admission rate - a nationwide cohort study of Swedish cancer patients. AB - BACKGROUND: Whether the emotional distress around cancer diagnosis is associated with the long-term outcomes and care utilization is unknown. We aimed to examine the association of mental disorders around cancer diagnosis with the hospital admission rates of cancer patients thereafter. METHODS: We conducted a nationwide cohort study including 218,508 cancer patients diagnosed in Sweden during 2004 2009 and followed them from 90 days after cancer through 2010. We used a clinical diagnosis of stress-related mental disorders from 90 days before to 90 days after cancer diagnosis as the exposure. We studied first all hospital admissions and then separately three common admissions, including external injuries, infections, and cardiovascular diseases. The Cox model was used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: Four thousand one hundred five patients received a diagnosis of stress-related mental disorders around the cancer diagnosis, and experienced a 35% increased rate of any hospital admission during follow-up (HR: 1.35, 95%CI: 1.28-1.41) as well as hospital admissions for external injuries (HR: 1.89, 95%CI: 1.67-2.14), infections (HR: 1.28, 95%CI: 1.08 1.52), and cardiovascular diseases (HR: 1.16, 95%CI: 1.03-1.30). Similar association was noted for most common cancer types. CONCLUSIONS: These data suggest that cancer patients diagnosed with a stress-related mental disorder immediately before or after cancer diagnosis are subsequently at increased risk of hospital admissions for major comorbidities of cancer. PMID- 29580233 TI - Oligohistidine and targeting peptide functionalized TAT-NLS for enhancing cellular uptake and promoting angiogenesis in vivo. AB - BACKGROUND: Gene therapy has been developed and used in medical treatment for many years, especially for the enhancement of endothelialization and angiogenesis. But slow endosomal escape rate is still one of the major barriers to successful gene delivery. In order to evaluate whether introducing oligohistidine (Hn) sequence into gene carriers can promote endosomal escape and gene transfection or not, we designed and synthesized Arg-Glu-Asp-Val (REDV) peptide functionalized TAT-NLS-Hn (TAT: typical cell-penetrating peptide, NLS: nuclear localization signals, Hn: oligohistidine sequence, n: 4, 8 and 12) peptides with different Hn sequence lengths. pEGFP-ZNF580 (pZNF580) was condensed by these peptides to form gene complexes, which were used to transfect human umbilical vein endothelial cells (HUVECs). RESULTS: MTT assay showed that the gene complexes exhibited low cytotoxicity for HUVECs. The results of cellular uptake and co-localization ratio demonstrated that the gene complexes prepared from TAT-NLS-Hn with long Hn sequence (n = 12) benefited for high internalization efficiency of pZNF580. In addition, the results of western blot analysis and PCR assay of REDV-TAT-NLS-H12/pZNF580 complexes showed significantly enhanced gene expression at protein and mRNA level. Wound healing assay and transwell migration assay also confirmed the improved proliferation and migration ability of the transfected HUVECs by these complexes. Furthermore, the in vitro and in vivo angiogenesis assay illustrated that these complexes could promote the tube formation ability of HUVECs. CONCLUSION: The above results indicated that the delivery efficiency of pZNF580 and its expression could be enhanced by introducing Hn sequence into gene carriers. The Hn sequence in REDV-TAT-NLS-Hn is beneficial for high gene transfection. These REDV and Hn functionalized TAT-NLS peptides are promising gene carriers in gene therapy. PMID- 29580234 TI - In vitro inhibition of porcine reproductive and respiratory syndrome virus replication by short antisense oligonucleotides with locked nucleic acid modification. AB - BACKGROUND: Porcine reproductive and respiratory syndrome virus (PRRSV) causes porcine reproductive and respiratory syndrome (PRRS), which is currently insufficiently controlled. From a previous small-scale screen we identified an effective DNA-based short antisense oligonucleotide (AS-ON) targeting viral NSP9, which could inhibit PRRSV replication in both Marc-145 cells and pulmonary alveolar macrophages (PAMs). The objective of this study was to explore the strategy of incorporating locked nucleic acids (LNAs) to achieve better inhibition of PRRSV replication in vitro. METHODS: The effective DNA-based AS-ON (YN8) was modified with LNAs at both ends as gap-mer (LNA-YN8-A) or as mix-mer (LNA-YN8-B). Marc-145 cells or PAMs were infected with PRRSV and subsequently transfected. RESULTS: Compared with the DNA-based YN8 control, the two AS-ONs modified with LNAs were found to be significantly more effective in decreasing the cytopathic effect (CPE) induced by PRRSV and thus in maintaining cell viability. LNA modifications conferred longer lifetimes to the AS-ON in the cell culture model. Viral ORF7 levels were more significantly reduced at both RNA and protein levels as shown by quantitative PCR, western blot and indirect immunofluorescence staining. Moreover, transfection with LNA modified AS-ON reduced the PRRSV titer by 10-fold compared with the YN8 control. CONCLUSION: Taken together, incorporation of LNA into AS-ON technology holds higher therapeutic promise for PRRS control. PMID- 29580235 TI - Performance of in silico prediction tools for the classification of rare BRCA1/2 missense variants in clinical diagnostics. AB - BACKGROUND: The use of next-generation sequencing approaches in clinical diagnostics has led to a tremendous increase in data and a vast number of variants of uncertain significance that require interpretation. Therefore, prediction of the effects of missense mutations using in silico tools has become a frequently used approach. Aim of this study was to assess the reliability of in silico prediction as a basis for clinical decision making in the context of hereditary breast and/or ovarian cancer. METHODS: We tested the performance of four prediction tools (Align-GVGD, SIFT, PolyPhen-2, MutationTaster2) using a set of 236 BRCA1/2 missense variants that had previously been classified by expert committees. However, a major pitfall in the creation of a reliable evaluation set for our purpose is the generally accepted classification of BRCA1/2 missense variants using the multifactorial likelihood model, which is partially based on Align-GVGD results. To overcome this drawback we identified 161 variants whose classification is independent of any previous in silico prediction. In addition to the performance as stand-alone tools we examined the sensitivity, specificity, accuracy and Matthews correlation coefficient (MCC) of combined approaches. RESULTS: PolyPhen-2 achieved the lowest sensitivity (0.67), specificity (0.67), accuracy (0.67) and MCC (0.39). Align-GVGD achieved the highest values of specificity (0.92), accuracy (0.92) and MCC (0.73), but was outperformed regarding its sensitivity (0.90) by SIFT (1.00) and MutationTaster2 (1.00). All tools suffered from poor specificities, resulting in an unacceptable proportion of false positive results in a clinical setting. This shortcoming could not be bypassed by combination of these tools. In the best case scenario, 138 families would be affected by the misclassification of neutral variants within the cohort of patients of the German Consortium for Hereditary Breast and Ovarian Cancer. CONCLUSION: We show that due to low specificities state-of-the-art in silico prediction tools are not suitable to predict pathogenicity of variants of uncertain significance in BRCA1/2. Thus, clinical consequences should never be based solely on in silico forecasts. However, our data suggests that SIFT and MutationTaster2 could be suitable to predict benignity, as both tools did not result in false negative predictions in our analysis. PMID- 29580236 TI - The FieldTrip-SimBio pipeline for EEG forward solutions. AB - BACKGROUND: Accurately solving the electroencephalography (EEG) forward problem is crucial for precise EEG source analysis. Previous studies have shown that the use of multicompartment head models in combination with the finite element method (FEM) can yield high accuracies both numerically and with regard to the geometrical approximation of the human head. However, the workload for the generation of multicompartment head models has often been too high and the use of publicly available FEM implementations too complicated for a wider application of FEM in research studies. In this paper, we present a MATLAB-based pipeline that aims to resolve this lack of easy-to-use integrated software solutions. The presented pipeline allows for the easy application of five-compartment head models with the FEM within the FieldTrip toolbox for EEG source analysis. METHODS: The FEM from the SimBio toolbox, more specifically the St. Venant approach, was integrated into the FieldTrip toolbox. We give a short sketch of the implementation and its application, and we perform a source localization of somatosensory evoked potentials (SEPs) using this pipeline. We then evaluate the accuracy that can be achieved using the automatically generated five-compartment hexahedral head model [skin, skull, cerebrospinal fluid (CSF), gray matter, white matter] in comparison to a highly accurate tetrahedral head model that was generated on the basis of a semiautomatic segmentation with very careful and time consuming manual corrections. RESULTS: The source analysis of the SEP data correctly localizes the P20 component and achieves a high goodness of fit. The subsequent comparison to the highly detailed tetrahedral head model shows that the automatically generated five-compartment head model performs about as well as a highly detailed four-compartment head model (skin, skull, CSF, brain). This is a significant improvement in comparison to a three-compartment head model, which is frequently used in praxis, since the importance of modeling the CSF compartment has been shown in a variety of studies. CONCLUSION: The presented pipeline facilitates the use of five-compartment head models with the FEM for EEG source analysis. The accuracy with which the EEG forward problem can thereby be solved is increased compared to the commonly used three-compartment head models, and more reliable EEG source reconstruction results can be obtained. PMID- 29580237 TI - Assessment of population coverage of hypertension screening in Thailand based on the effective coverage framework. AB - BACKGROUND: Hypertension (HT) is a major risk factor, and accessible and effective HT screening services are necessary. The effective coverage framework is an assessment tool that can be used to assess health service performance by considering target population who need and receive quality service. The aim of this study is to measure effective coverage of hypertension screening services at the provincial level in Thailand. METHODS: Over 40 million individual health service records in 2013 were acquired. Data on blood pressure measurement, risk assessment, HT diagnosis and follow up were analyzed. The effectiveness of the services was assessed based on a set of quality criteria for pre-HT, suspected HT, and confirmed HT cases. Effective coverage of HT services for all non-HT Thai population aged 15 or over was estimated for each province and for all Thailand. RESULTS: Population coverage of HT screening is 54.6%, varying significantly across provinces. Among those screened, 28.9% were considered pre-HT, and another 6.0% were suspected HT cases. The average provincial effective coverage was at 49.9%. Around four-fifths (82.6%) of the pre-HT group received HT and Cardiovascular diseases (CVD) risk assessment. Among the suspected HT cases, less than half (38.0%) got a follow-up blood pressure measurement within 60 days from the screening date. Around 9.2% of the suspected cases were diagnosed as having HT, and only one-third of them (36.5%) received treatment within 6 months. Within this group, 21.8% obtained CVD risk assessment, and half of them had their blood pressure under control (50.8%) with less than 1 % (0.7%) of them managed to get the CVD risk reduced. CONCLUSIONS: Our findings suggest that hypertension screening coverage, post-screening service quality, and effective coverage of HT screening in Thailand were still low and they vary greatly across provinces. It is imperative that service coverage and its effectiveness are assessed, and both need improvement. Despite some limitations, measurement of effective coverage could be done with existing data, and it can serve as a useful tool for performance measurement of public health services. PMID- 29580238 TI - The effectiveness of treatment for Severe Acute Malnutrition (SAM) delivered by community health workers compared to a traditional facility based model. AB - BACKGROUND: In most health systems, Community Health Workers (CHWs) identify and screen for severe acute malnutrition (SAM) in the community. This study aimed to investigate the potential of integrating SAM identification and treatment delivered by CHWs, in order to improve the coverage of SAM treatment services. METHODS: This multicentre, randomised intervention study was conducted in Kita, Southwest Mali between February 2015 and February 2016. Treatment for uncomplicated SAM was provided in health facilities in the control area, and by Community Health Workers and health facilities in the intervention area. Clinical outcomes (cure, death and defaulter ratios), treatment coverage and quality of care were examined in both the control and intervention group. RESULTS: Six hundred ninety nine children were admitted to the intervention group and 235 children to the control group. The intervention group reported cure ratios of 94.2% compared to 88.6% in the control group (risk ratio 1.07 [95% CI 1.01; 1.13]). Defaulter ratios were twice as high in the control group compared to the intervention group (10.8% vs 4.5%; RR 0.42 [95% CI 0.25; 0.71]). Differences in mortality ratios were not statistically significant (0.9% in the intervention group compared to 0.8% in the control group). Coverage rates in December 2015 were 86.7% in intervention group compared to 41.6% in the control (p < 0.0001). CONCLUSIONS: With minimal training, CHWs are able to appropriately treat SAM in the community. Allowing CHWs to treat SAM reduces defaulter ratios without compromising treatment outcomes and can lead to improved access to treatment.

PMID- 29580239 TI - Is double-approach surgery and tenodesis without a gastrocnemius flap better for dealing with proximal fibular osteosarcoma? AB - BACKGROUND: Resection of proximal fibular osteosarcoma involving the posteromedial aspect of the fibula is challenging. Reconstruction using a gastrocnemius flap may result in significant lateral instability and abnormal knee movement. Furthermore, postoperative gait may be disturbed by foot drop resulting from scarification of the common peroneal nerve. METHODS: Between January 2011 and December 2013, five patients with proximal fibular osteosarcoma were treated via the double-approach procedure using en bloc resection without a gastrocnemius flap. Simultaneously, all patients received one-stage tenodesis of the anterior tibial and toe extensor tendons. Clinical outcomes, including local tumor recurrence, complications, and functional outcomes, were evaluated. RESULTS: The mean follow-up duration was 47.2 months (range 42-52 months). No patients experienced local recurrence. The patients' Enneking functional scores were excellent (80%) or good (20%) at the final follow-up. CONCLUSIONS: In patients with proximal fibular osteosarcoma, the double-approach procedure allows easier and safer en bloc tumor resection with vessel and nerve protection. One stage tenodesis without a gastrocnemius flap is associated with good functional outcomes. PMID- 29580240 TI - Exploring native genetic elements as plug-in tools for synthetic biology in the cyanobacterium Synechocystis sp. PCC 6803. AB - BACKGROUND: The unicellular cyanobacterium Synechocystis sp. PCC 6803 has been widely used as a photoautotrophic host for synthetic biology studies. However, as a green chassis to capture CO2 for biotechnological applications, the genetic toolbox for Synechocystis 6803 is still a limited factor. RESULTS: We systematically characterized endogenous genetic elements of Synechocystis 6803, including promoters, ribosome binding sites, transcription terminators, and plasmids. Expression from twelve native promoters was compared by measuring fluorescence from the reporter protein EYFP in an identical setup, exhibiting an 8000-fold range of promoter activities. Moreover, we measured the strength of twenty native ribosome binding sites and eight native terminators, indicating their influence on the expression of the reporter genes. In addition, two shuttle vectors, pCA-UC118 and pCB-SC101, capable of replication in both Synechocystis 6803 and E. coli were constructed. Expression of reporter proteins were significantly enhanced in cells containing these new plasmids, thus providing superior gene expression platforms in this cyanobacterium. CONCLUSIONS: The results of this study provide useful and well characterized native tools for bioengineering work in the model cyanobacterium Synechocystis 6803. PMID- 29580241 TI - Enhanced expression of histone chaperone APLF associate with breast cancer. AB - DNA damage-specific histone chaperone Aprataxin PNK-like factor (APLF) regulates mesenchymal-to-epithelial transition (MET) during cellular reprogramming. We investigated the role of APLF in epithelial-to-mesenchymal transition (EMT) linked to breast cancer invasiveness and metastasis. Here, we show that a significant manifestation of APLF is present in tumor sections of patients with invasive ductal carcinoma when compared to their normal adjacent tissues. APLF was significantly induced in triple negative breast cancer (TNBC) cells, MDAMB 231, in comparison to invasive MCF7 or normal MCF10A breast cells and supported by studies on invasive breast carcinoma in The Cancer Genome Atlas (TCGA). Functionally, APLF downregulation inhibited proliferative capacity, altered cell cycle behavior, induced apoptosis and impaired DNA repair ability of MDAMB-231 cells. Reduction in APLF level impeded invasive, migratory, tumorigenic and metastatic potential of TNBC cells with loss in expression of genes associated with EMT while upregulation of MET-specific gene E-cadherin (CDH1). So, here we provided novel evidence for enrichment of APLF in breast tumors, which could regulate metastasis-associated EMT in invasive breast cancer. We anticipate that APLF could be exploited as a biomarker for breast tumors and additionally could be targeted in sensitizing cancer cells towards DNA damaging agents. PMID- 29580242 TI - Plasma procalcitonin concentrations predict organ dysfunction and outcome in dogs with sepsis. AB - BACKGROUND: Procalcitonin (PCT) is a valuable prognostic biomarker in human sepsis that is predictive of organ dysfunction, septic shock and mortality. Data on PCT in dogs is limited. This study aimed to investigate the prognostic value of baseline and serial PCT measurements in dogs with sepsis and to determine the association between PCT and sepsis severity and the presence of organ dysfunction. PCT concentrations were measured in citrated plasma samples collected from 53 dogs with sepsis at the time of admission (T0, n = 53) and at 24 h (T1, n = 35) and 48 h (T2, n = 30) post-admission using a commercial ELISA. Dogs were classified by sepsis severity (sepsis without organ dysfunction; severe sepsis; septic shock) and outcome (survivors; non-survivors). Organ dysfunctions were recorded at T0 and during hospitalization, and the APPLEfast score calculated at T0. Healthy dogs (n = 12) were used as controls. RESULTS: There were 18 septic dogs without organ dysfunction, 24 dogs with severe sepsis and 11 with septic shock. Baseline PCT concentrations were significantly greater in dogs with sepsis compared to healthy controls (P < 0.0001), and in dogs with septic shock compared to dogs without cardiovascular compromise (P = 0.01). Baseline PCT was significantly correlated with organ dysfunction (P = 0.003). Declining PCT concentrations were documented in survivors at T1 and T2 compared to PCT at T0 (P = 0.0006), and PCT clearance at 24 h was significantly higher in survivors (n = 38) compared to non-survivors (n = 15) (P = 0.037). Canine APPLEfast score was not predictive of sepsis severity, the development of MODS or outcome. CONCLUSION: In dogs with sepsis, PCT concentrations at hospital admissions are predictive of organ dysfunction and septic shock. Serial procalcitonin monitoring may offer valuable prognostic information in canine sepsis, wherein early decreases in PCT concentrations are associated with survival. PMID- 29580243 TI - Factors associated with the use of cognitive aids in operating room crises: a cross-sectional study of US hospitals and ambulatory surgical centers. AB - BACKGROUND: Operating room (OR) crises are high-acuity events requiring rapid, coordinated management. Medical judgment and decision-making can be compromised in stressful situations, and clinicians may not experience a crisis for many years. A cognitive aid (e.g., checklist) for the most common types of crises in the OR may improve management during unexpected and rare events. While implementation strategies for innovations such as cognitive aids for routine use are becoming better understood, cognitive aids that are rarely used are not yet well understood. We examined organizational context and implementation process factors influencing the use of cognitive aids for OR crises. METHODS: We conducted a cross-sectional study using a Web-based survey of individuals who had downloaded OR cognitive aids from the websites of Ariadne Labs or Stanford University between January 2013 and January 2016. In this paper, we report on the experience of 368 respondents from US hospitals and ambulatory surgical centers. We analyzed the relationship of more successful implementation (measured as reported regular cognitive aid use during applicable clinical events) with organizational context and with participation in a multi-step implementation process. We used multivariable logistic regression to identify significant predictors of reported, regular OR cognitive aid use during OR crises. RESULTS: In the multivariable logistic regression, small facility size was associated with a fourfold increase in the odds of a facility reporting more successful implementation (p = 0.0092). Completing more implementation steps was also significantly associated with more successful implementation; each implementation step completed was associated with just over 50% higher odds of more successful implementation (p <= 0.0001). More successful implementation was associated with leadership support (p < 0.0001) and dedicated time to train staff (p = 0.0189). Less successful implementation was associated with resistance among clinical providers to using cognitive aids (p < 0.0001), absence of an implementation champion (p = 0.0126), and unsatisfactory content or design of the cognitive aid (p = 0.0112). CONCLUSIONS: Successful implementation of cognitive aids in ORs was associated with a supportive organizational context and following a multi-step implementation process. Building strong organizational support and following a well-planned multi-step implementation process will likely increase the use of OR cognitive aids during intraoperative crises, which may improve patient outcomes. PMID- 29580244 TI - Simultaneous detection of Plasmodium vivax dhfr, dhps, mdr1 and crt-o resistance associated mutations in the Colombian Amazonian region. AB - BACKGROUND: Malaria continues being a public health problem worldwide. Plasmodium vivax is the species causing the largest number of cases of malaria in Asia and South America. Due to the lack of a completely effective anti-malarial vaccine, controlling this disease has been based on transmission vector management, rapid diagnosis and suitable treatment. However, parasite resistance to anti-malarial drugs has become a major yet-to-be-overcome challenge. This study was thus aimed at determining pvmdr1, pvdhfr, pvdhps and pvcrt-o gene mutations and haplotypes from field samples obtained from an endemic area in the Colombian Amazonian region. METHODS: Fifty samples of parasite DNA infected by a single P. vivax strain from symptomatic patients from the Amazonas department in Colombia were analysed by PCR and the pvdhfr, pvdhps, pvmdr1 and pvcrt-o genes were sequenced. Diversity estimators were calculated from the sequences and the haplotypes circulating in the Colombian Amazonian region were obtained. CONCLUSION: pvdhfr, pvdhps, pvmdr1 and pvcrt-o genes in the Colombian Amazonian region are characterized by low genetic diversity. Some resistance-associated mutations were found circulating in this population. New variants are also being reported. A selective sweep signal was located in pvdhfr and pvmdr1 genes, suggesting that these mutations (or some of them) could be providing an adaptive advantage. PMID- 29580245 TI - The clinical relevance of advanced artificial feedback in the control of a multi functional myoelectric prosthesis. AB - BACKGROUND: To effectively replace the human hand, a prosthesis should seamlessly respond to user intentions but also convey sensory information back to the user. Restoration of sensory feedback is rated highly by the prosthesis users, and feedback is critical for grasping in able-bodied subjects. Nonetheless, the benefits of feedback in prosthetics are still debated. The lack of consensus is likely due to the complex nature of sensory feedback during prosthesis control, so that its effectiveness depends on multiple factors (e.g., task complexity, user learning). METHODS: We evaluated the impact of these factors with a longitudinal assessment in six amputee subjects, using a clinical setup (socket, embedded control) and a range of tasks (box and blocks, block turn, clothespin and cups relocation). To provide feedback, we have proposed a novel vibrotactile stimulation scheme capable of transmitting multiple variables from a multifunction prosthesis. The subjects wore a bracelet with four by two uniformly placed vibro-tactors providing information on contact, prosthesis state (active function), and grasping force. The subjects also completed a questionnaire for the subjective evaluation of the feedback. RESULTS: The tests demonstrated that feedback was beneficial only in the complex tasks (block turn, clothespin and cups relocation), and that the training had an important, task-dependent impact. In the clothespin relocation and block turn tasks, training allowed the subjects to establish successful feedforward control, and therefore, the feedback became redundant. In the cups relocation task, however, the subjects needed some training to learn how to properly exploit the feedback. The subjective evaluation of the feedback was consistently positive, regardless of the objective benefits. These results underline the multifaceted nature of closed-loop prosthesis control as, depending on the context, the same feedback interface can have different impact on performance. Finally, even if the closed-loop control does not improve the performance, it could be beneficial as it seems to improve the subjective experience. CONCLUSIONS: Therefore, in this study we demonstrate, for the first time, the relevance of an advanced, multi-variable feedback interface for dexterous, multi-functional prosthesis control in a clinically relevant setting.

PMID- 29580247 TI - Nationwide insecticide resistance status and biting behaviour of malaria vector species in the Democratic Republic of Congo. AB - BACKGROUND: Globally, the Democratic Republic of Congo (DRC) accounted for 9% of malaria cases and 10% of malaria deaths in 2015. As part of control efforts, more than 40 million long-lasting insecticidal nets (LLINs) were distributed between 2008 and 2013, resulting in 70% of households owning one or more LLINs in 2014. To optimize vector control efforts, it is critical to monitor vector behaviour and insecticide resistance trends. Entomological data was collected from eight sentinel sites throughout DRC between 2013 and 2016 in Kingasani, Mikalayi, Lodja, Kabondo, Katana, Kapolowe, Tshikaji and Kalemie. Mosquito species present, relative densities and biting times were monitored using human landing catches (HLC) conducted in eight houses, three times per year. HLC was conducted monthly in Lodja and Kapolowe during 2016 to assess seasonal dynamics. Laboratory data included resistance mechanism frequency and sporozoite rates. Insecticide susceptibility testing was conducted with commonly used insecticides including deltamethrin and permethrin. Synergist bioassays were conducted with PBO to determine the role of oxidases in permethrin resistance. RESULTS: In Lodja, monthly Anopheles gambiae s.l. biting rates were consistently high at > 10 bites/person/night indoors and outdoors. In Kapolowe, An. gambiae s.l. dominated during the rainy season, and Anopheles funestus s.l. during the dry season. In all sites, An. gambiae and An. funestus biting occurred mostly late at night. In Kapolowe, significant biting of both species started around 19:00, typically before householders use nets. Sporozoite rates were high, with a mean of 4.3% (95% CI 3.4-5.2) for An. gambiae and 3.3% (95% CI 1.3-5.3) for An. funestus. Anopheles gambiae were resistant to permethrin in six out of seven sites in 2016. In three sites, susceptibility to deltamethrin was observed despite high frequency permethrin resistance, indicating the presence of pyrethroid-specific resistance mechanisms. Pre-exposure to PBO increased absolute permethrin associated mortality by 24%, indicating that resistance was partly due to metabolic mechanisms. The kdr-1014F mutation in An. gambiae was present at high frequency (> 70%) in three sites (Kabondo, Kingasani and Tshikaji), and lower frequency (< 20%) in two sites (Lodja and Kapolowe). CONCLUSION: The finding of widespread resistance to permethrin in DRC is concerning and alternative insecticides should be evaluated. PMID- 29580248 TI - Knockdown of IFI27 inhibits cell proliferation and invasion in oral squamous cell carcinoma. AB - BACKGROUND: The development of oral squamous cell carcinoma (OSCC) involves genetic mutations, epigenetic gene expression modification, and other processes. It has been reported that IFI27 is upregulated in OSCC, but its function is unknown. The aim of this study was to investigate the role of IFI27 on OSCC cell proliferation and invasion. METHODS: The protein level of IFI27 in OSCC tissues and adjacent tissues was detected by immunohistochemistry. In the OSCC cell model, we designed the IFI27 siRNA to downregulate the expression of IFI27; gene and protein of IFI27 in those models were then detected by Q-PCR and Western blot. MTT assay was used to detect the effect of -IFI27 knockdown on cell proliferation; Annexin V-PI staining flow cytometry was used to detect the effect of IFI27 downregulation on apoptosis of cancer cells. The effect of IFI27 downregulation on oral cancer cell invasion was detected using Transwell assay. RESULTS: IFI27 was highly expressed in OSCC tissues by immunohistochemical assay. In the OSCC cell model, IFI27 siRNA could downregulate the mRNA and protein expression level of IFI27. As showed in MTT assay, Annexin V-PI assay, and Transwell assay, through the downregulation of IFI27, TSCCA and TCA8113 cell proliferation were inhibited, OSCC cell apoptosis was promoted, and its migration and invasion were inhibited. CONCLUSION: IFI27 is involved in the development and progression of OSCC. Its high expression promotes cell proliferation and invasion and reduces apoptosis. These findings may provide new biomarkers and therapeutic targets for OSCC diagnosis and clinical treatment. PMID- 29580249 TI - Evaluation of a program for routine implementation of shared decision-making in cancer care: study protocol of a stepped wedge cluster randomized trial. AB - BACKGROUND: Shared decision-making (SDM) has become increasingly important in health care. However, despite scientific evidence, effective implementation strategies, and a prominent position on the health policy agenda, SDM is not widely implemented in routine practice so far. Therefore, we developed a program for routine implementation of SDM in oncology by conducting an analysis of the current state and a needs assessment in a pilot study based on the Consolidated Framework for Implementation Research (CFIR). Based on these results, the main aim of our current study is to evaluate the process and outcome of this theoretically and empirically grounded multicomponent implementation program designed to foster SDM in routine cancer care. METHODS: We use a stepped wedge design, a variant of the cluster randomized controlled trial. The intervention to be implemented is SDM. Three participating clinics of one comprehensive cancer center will be randomized and receive the multicomponent SDM implementation program in a time-delayed sequence. The program consists of the following strategies: (a) SDM training for health care professionals, (b) individual coaching for physicians, (c) patient activation strategy, (d) provision of patient information material and decision aids, (e) revision of the clinics' quality management documents, and (f) critical reflection of current organization of multidisciplinary team meetings. We will conduct a mixed methods outcome and process evaluation. The outcome evaluation will consist of four measurement points. The primary outcome is adoption of SDM, measured by the 9-item Shared Decision Making Questionnaire. A range of other implementation outcomes will be assessed (i.e., acceptability, readiness for implementing change, appropriateness, penetration). The implementation process will be evaluated using stakeholder interviews and field notes. This will allow adapting interventions if necessary. DISCUSSION: This study is the first large study on routine implementation of SDM conducted in German cancer care. We expect to foster implementation of SDM at the enrolled clinics. Insights gained from this study, using a theoretically and empirically grounded approach, can inform other SDM implementation studies and health policy developments, both nationally and internationally. TRIAL REGISTRATION: clinicaltrials.gov, NCT03393351 . Registered 8 January 2018. PMID- 29580250 TI - Effectiveness of Omega-3 fatty acid for polycystic ovary syndrome: a systematic review and meta-analysis. AB - OBJECTIVE: To assess the effectiveness and safety of omega-3 fatty acid for patients with PCOS. METHODS: In this meta-analysis, data from randomized controlled trials were obtained to assess the effects of omega-3 fatty acid versus placebo or western medicine in women with PCOS. The study's registration number is CRD42017065859. The primary outcomes included the change of homeostatic model assessment (HOMA) of insulin resistance, total cholesterol (TC), triglyceride (TG) and adiponectin. RESULT: Nine trials involving 591 patients were included. Comparing with the control group, omega-3 fatty acid may improve HOMA index (WMD -0.80; 95% CI -0.89, - 0.71; P<0. 00001), decrease TC and TG level [TC: (WMD -9.43; 95% CI -11.90, - 6.95; P<0. 00001); TG: (WMD -29.21; 95% CI -48.08, - 10.34; P = 0. 002)], and increase adiponectin level (WMD 1.34; 95% CI 0.51, 2.17; P = 0. 002). CONCLUSION: Based on current evidence, omega-3 fatty acid may be recommended for the treatment of PCOS with insulin resistance as well as high TC (especially LDL-C) and TG. PMID- 29580252 TI - Early musculoskeletal classroom education confers little advantage to medical student knowledge and competency in the absence of clinical experiences: a retrospective comparison study. AB - BACKGROUND: Deficiencies in medical student knowledge in musculoskeletal medicine have been well documented. To address these deficiencies, numerous curricular changes at our institution were instituted. The objective of this study was to determine whether medical students in their preclinical years benefit from early exposure to musculoskeletal medicine when compared to students exposed to musculoskeletal medicine just prior to completion of their preclinical curriculum. METHODS: United States Medical Licensing Examination (USMLE) Step 1 and 2 scores were compared for periods of time before and after institution of the new curriculum. Scores on the previously validated 24-question short answer survey from Freedman and Bernstein were also compared over these same periods of time between these two groups and to established standards for competency, using a student's two-tailed unpaired t-test for significance. Entering Medical College Admission Test (MCAT) scores were used to compare baseline preparation of students. RESULTS: Overall USMLE scores as well as scores on the USMLE subtest on Musculoskeletal, Skin and Connective Tissue Disease showed no improvement when scores were compared between the two groups of students. There was a statistically significant lower performance on the Freedman and Bernstein knowledge assessment exam for students in the new pre-clinical curriculum as compared to those introduced under the old model, considering both musculoskeletal knowledge (p < 0.001) and proficiency (p < 0.01), though the response rate on the recent survey was low (112/986 or 11%). Spine remained the least understood sub-topic, while a dedicated course in rheumatology likely contributed to increased student knowledge in that area. Additional exposure to musculoskeletal topics during the clinical years increased student knowledge. There was no difference between groups when comparing entering MCAT scores. CONCLUSIONS: Classroom curricular changes, including moving the introductory musculoskeletal course to the first year, intended to optimize musculoskeletal medicine education in the pre-clinical years of medical school did not appear to improve student musculoskeletal knowledge at any year of training. Further efforts to improve the education of medical students in musculoskeletal medicine should be directed towards providing more clinical experiences with patients having musculoskeletal concerns. This was a retrospective comparative study, level III evidence. PMID- 29580251 TI - Defining the external implementation context: an integrative systematic literature review. AB - BACKGROUND: Proper implementation of evidence-based interventions is necessary for their full impact to be realized. However, the majority of research to date has overlooked facilitators and barriers existing outside the boundaries of the implementing organization(s). Better understanding and measurement of the external implementation context would be particularly beneficial in light of complex health interventions that extend into and interact with the larger environment they are embedded within. We conducted a integrative systematic literature review to identify external context constructs likely to impact implementation of complex evidence-based interventions. METHODS: The review process was iterative due to our goal to inductively develop the identified constructs. Data collection occurred in four primary stages: (1) an initial set of key literature across disciplines was identified and used to inform (2) journal and (3) author searches that, in turn, informed the design of the final (4) database search. Additionally, (5) we conducted citation searches of relevant literature reviews identified in each stage. We carried out an inductive thematic content analysis with the goal of developing homogenous, well-defined, and mutually exclusive categories. RESULTS: We identified eight external context constructs: (1) professional influences, (2) political support, (3) social climate, (4) local infrastructure, (5) policy and legal climate, (6) relational climate, (7) target population, and (8) funding and economic climate. CONCLUSIONS: This is the first study to our knowledge to use a systematic review process to identify empirically observed external context factors documented to impact implementation. Comparison with four widely-utilized implementation frameworks supports the exhaustiveness of our review process. Future work should focus on the development of more stringent operationalization and measurement of these external constructs. PMID- 29580253 TI - Excessive nerve growth factor impairs bidirectional communication between the oocyte and cumulus cells resulting in reduced oocyte competence. AB - BACKGROUND: Excessive nerve growth factor (NGF) is commonly found in the follicular fluid of patients with polycystic ovary syndrome (PCOS). Furthermore, oocytes from PCOS patients exhibit lower developmental competence. The purpose of this study was to explore the association between excessive NGF and low oocyte competence in vitro. METHODS: Excessive NGF was added to mouse cumulus oocyte complexes (COCs) cultured in vitro to investigate meiotic maturation of the oocyte. After culture, mRNA expression levels of Pfkp and Ldha genes in cumulus cells (CCs) and Gdf9, Bmp15 and Fgf8 genes in oocytes, were determined by real time quantitative polymerase chain reaction (qPCR). We also investigated the mRNA content of Pfkp and Ldha in CCs from PCOS and non-PCOS patients. RESULTS: Excessive NGF significantly inhibited oocyte meiotic maturation. The inhibitory effect was mediated by the NGF high-affinity receptor, NTRK1. mRNA content of Pfkp and Ldha genes in CCs was significantly reduced by excessive NGF stimulation. Moreover, the expression levels of Gdf9, Bmp15 and Fgf8 were also decreased in oocytes, and was induced by excessive NGF-stimulated CCs. In addition, lower expression levels of Pfkp and Ldha in CCs were identified in Chinese PCOS patients with excessive NGF (PCOS, 22 +/- 2.63 ng/ml, n = 13; non PCOS, 7.18 +/- 2.42 ng/ml, n = 9; p < 0.01) in the follicular fluid, suggesting a potential association between excessive NGF and decreased glycolysis in the CCs of women with PCOS. CONCLUSIONS: Excessive NGF impairs bidirectional communication between oocyte and cumulus cells, which might be related to low oocyte competence. PMID- 29580254 TI - Implementation of surgical debriefing programs in large health systems: an exploratory qualitative analysis. AB - BACKGROUND: The role of the "debrief" to address issues related to patient safety and systematic flaws in care is frequently overlooked. In our study, we interview surgical leaders who have developed successful strategies of debriefing within a comprehensive program of quality improvement. METHODS: Semi-structured interviews of four implementation leaders were performed. The observations, beliefs and strategies of surgical leaders are compared and contrasted. Common themes are identified related to program success and failure. Quality and safety researchers performed, coded and categorized the interviews and coordinated the analysis and interpretation of the results. The authors from the four institutions aided in interpretation and framing of the results. RESULTS: The debriefing programs evaluated were part of comprehensive quality improvement projects. Seven high level themes and 24 subthemes were identified from the interviews. Themes related to leadership included early engagement, visible ongoing commitment and enforcement. Success appeared to depend upon meaningful and early debriefing feedback. The culture of safety that promoted success included a commitment to open and fair communication and continuous improvement. There were many challenges to the success of debriefing programs. The loss of institutional commitment of resources and personnel was the instigating factor behind the collapse of the program at Michigan. Other areas of potential failure included communication issues and loss of early and meaningful feedback. CONCLUSIONS: Leaders of four surgical systems with strong debriefing programs report success using debriefing to improve system performance. These findings are consistent with previously published studies. Success requires commitment of resources, and leadership engagement. The greatest gains may be best achieved by programs that provide meaningful debriefing feedback in an atmosphere dedicated to open communication. PMID- 29580255 TI - Total energy expenditure in adults aged 65 years and over measured using doubly labelled water: international data availability and opportunities for data sharing. AB - BACKGROUND: Increasing population lifespan necessitates a greater understanding of nutritional needs in older adults (65 year and over). A synthesis of total energy expenditure in the older population has not been undertaken and is needed to inform nutritional requirements. We aimed to establish the extent of the international evidence for total energy expenditure (TEE) using doubly-labelled water (DLW) in older adults (65 years and over), report challenges in obtaining primary data, and make recommendations for future data sharing. METHODS: Four databases were searched to identify eligible studies; original research of any study design where participant level TEE was measured using DLW in participants aged >=65 years. Once studies were identified for inclusion, authors were contacted where data were not publicly available. RESULTS: Screening was undertaken of 1223 records; the review of 317 full text papers excluded 170 records. Corresponding or first authors of 147 eligible studies were contacted electronically. Participant level data were publicly available or provided by authors for 45 publications (890 participants aged >=65 years, with 248 aged >=80 years). Sixty-seven percent of the DLW data in this population were unavailable due to authors unable to be contacted or declining to participate, or data being irretrievable. CONCLUSIONS: The lack of data access limits the value of the original research and its contribution to nutrition science. Openly accessible DLW data available through publications or a new international data repository would facilitate greater integration of current research with previous findings and ensure evidence is available to support the needs of the ageing population. TRIAL REGISTRATION: The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42016047549 . PMID- 29580256 TI - Utilization of institutional delivery service and associated factors among mothers in North West Ethiopian. AB - OBJECTIVE: The aim of this study was to assess institutional delivery and its associated factors in Benishangul-Gumez region, North-West of Ethiopia. The data were obtained at community level in a single survey within 1 month and there is no continuation of this study or previously published part elsewhere. RESULTS: Among the 428 eligible respondents recruited for this study, 427 of them responded completely to the interview, giving a response rate of 99.8%. Of the total (427) respondents, 51.1% women delivered the recent child at health facility in the 12 months preceding the survey. Among the common reasons for home delivery were, labour was urgent (25.8%), home birth was usual habit for them (23.9%) and distance to health center was too far. Age (AOR = 3.4, 95% CI 1.46, 7.97), husband occupation (AOR = 5.16, 95% CI 1.74, 15.31), frequency of antenatal care visit (AOR = 3.34, 95% CI 1.88, 5.94) and maternal knowledge on danger signs of pregnancy and delivery (AOR = 7.18, 95% CI 3.77, 13.66) were significantly associated factors with institutional delivery. Although, the prevalence of institutional delivery has improved when compared to previous reports, strategic modification is important to increase health facility delivery.

AB - Immune checkpoint inhibitors (ICIs) therapy is a novel strategy for cancer treatments in recent years. However, it was observed that most patients treated with ICIs could not get benefit from the therapy, which led to the limitation of clinical application. Motivated by potent and durable efficacy of ICIs, oncologists endeavor to explore the mechanisms of resistance to ICIs and increase the drug sensitivity. It is known that heterogeneity of gut microbiome in populations may result in different outcomes of therapy. In xenograft model, bacteria in gut have been proved as a crucial factor regulating immunotherapy efficacy. And the similar phenomenon was obtained in patients. In this review, we summarized relevant advancements about gut microbiome and ICIs. Furthermore, we focused on modulatory function of gut microbiome in ICIs therapy and possible antitumor mechanism of specific commensals in ICIs treatment. We propose that gut microbiome is an important predictive factor, and manipulation of gut microbiome is feasible to elevate response rate in ICIs therapy. PMID- 29580258 TI - Detection of Creutzfeldt-Jakob disease prions in skin: implications for healthcare. AB - Evidence has recently been reported of prion seeding activity in skin tissue from patients with sporadic Creutzfeldt-Jakob disease (sCJD). This is relevant information for infection control measures during surgery. The work uses very sensitive prion assays now available for medical research, and may soon be adapted to related neurodegenerative disorders. PMID- 29580260 TI - Systematic Techniques to Enhance rEtention in Randomised controlled trials: the STEER study protocol. AB - BACKGROUND: Non-retention of participants seriously affects the credibility of clinical trial results and significantly reduces the potential of a trial to influence clinical practice. Non-retention can be defined as instances where participants leave the study prematurely. Examples include withdrawal of consent and loss to follow-up and thus outcome data cannot be obtained. The majority of existing interventions targeting retention fail to describe any theoretical basis for the observed improvement, or lack of improvement. Moreover, most of these interventions lack involvement of participants in their conception and/or design, raising questions about their relevance and acceptability. Many of the causes of non-retention involve people performing a behaviour (e.g. not returning a questionnaire). Behaviour change is difficult, and the importance of a strong theoretical basis for interventions that aim to change behaviour is increasingly recognised. This research aims to develop and pilot theoretically informed, participant-centred, evidence-based behaviour change interventions to improve retention in trials. METHODS: This research will generate data through semi structured interviews on stakeholders' perspectives of the reasons for trial non retention. It will identify perceived barriers and enablers to trial retention using the Theoretical Domains Framework. The intervention development work will involve identification of behaviour change techniques, using recognised methodology, and co-production of retention interventions through discussion groups with end-users. An evaluation of intervention acceptability and feasibility will be conducted in focus groups. Finally, a ready-to-use evaluation framework to deploy in Studies Within A Trial as well as an explanatory retention framework will be developed for identifying and tackling modifiable issues to improve trial retention. DISCUSSION: We believe this to be one of the first studies to apply a theoretical lens to the development of interventions to improve trial retention that have been informed by, and are embedded within, participants' experiential accounts. By developing and identifying priority interventions this study will support efforts to reduce research waste. PMID- 29580261 TI - A novel Babesia orientalis 135-kilodalton spherical body protein like: identification of its secretion into cytoplasm of infected erythrocytes. AB - BACKGROUND: The spherical body is a distinct organelle only existing in Babesia and Theileria. Spherical body proteins (SBPs) are secreted from spherical bodies and incorporated into the cytoplasm of infected erythrocytes during invasion and post-invasion stages. Four different SBP homologues (SBP1, SBP2, SBP3 and SBP4) have been identified in Babesia bovis and Babesia bigemina. So far, there has been no report available about the identification of SBPs in Babesia orientalis. METHODS: The SBP3-like in B. orientalis (BoSBP3-like) was cloned, sequenced, characterized and compared to the SBP3 sequences of B. bovis and B. bigemina by bioinformatics analyses. The BoSBP3-like gene was truncated into three fragments: BoSBP3-like-1 (915 bp), BoSBP3-like-2 (1311 bp) and BoSBP3-like-3 (1011 bp), which were amplified and cloned into the expression vector pET-28a and expressed as three truncated recombinant (His-fusion) proteins. The immunogenicity, native forms and localization of BoSBP3-like were identified by western blot and indirect immunofluorescence assay (IFA). RESULTS: The BoSBP3-like gene was intronless with an open reading frame (ORF) of 3237 bp, encoded a 1079 amino acid polypeptide with a predicted size of 135 kDa, and contained a cysteine-rich region, three dispersing FAINT domains and a signal peptide (1-16 aa) at the N terminus. The amino acid sequence of BoSBP3-like was 61.6 and 35.0% identical to that of B. bovis and B. bigemina, respectively. BoSBP3-like was identified as 135 kDa in the parasite lysate by rabbit antiserum against the truncated recombinant BoSBP3-like-1 (rBoSBP3-like-1). Three specific bands corresponding to rBoSBP3 like-1 (1-305 aa, 43 kDa), rBoSBP3-like-2 (306-742 aa, 58 kDa) and rBoSBP3-like-3 (743-1079 aa, 52 kDa) were detected by reaction with serum from B. orientalis infected buffalo. The BoSBP3-like was not only localized in the spherical body of B. orientalis but also in the cytoplasm of infected erythrocytes of buffalo as puncta-like protein specks at both single and paired parasite development stages. CONCLUSIONS: Through secretion into the cytoplasm of infected erythrocytes, BoSBP3-like may play a significant role in adaptation, interaction, and modification related to the host environment to benefit the growth and survival of Babesia. BoSBP3-like could react with the serum from B. orientalis-infected buffalo, but not healthy buffalo, implicating that BoSBP3-like is highly antigenic and may serve as a candidate diagnostic antigen for the detection of B. orientalis. PMID- 29580262 TI - Treatment of B-cell precursor acute lymphoblastic leukemia with the Galectin-1 inhibitor PTX008. AB - BACKGROUND: Drug resistance of B-cell precursor acute lymphoblastic leukemia (BP ALL) cells is conferred by both intrinsic and extrinsic factors, which could be targeted to promote chemo-sensitization. Our previous studies showed that Galectin-3, a lectin that clusters galactose-modified glycoproteins and that has both an intracellular and extracellular location, protects different subtypes of BP-ALL cells against chemotherapy. Galectin-1 is related to Galectin-3 and its expression was previously reported to be restricted to the MLL subtype of BP-ALL. METHODS AND RESULTS: Here, we report that Galectin-1 is expressed at different levels in and on different subclasses of BP-ALLs. Bone marrow plasma also contains high levels of Galectin-1. PTX008 is an allosteric inhibitor which inhibits Galectin-1 but not Galectin-3-mediated agglutination. The compound reduces migration of BP-ALL cells to CXCL12 and OP9 stromal cells and inhibits fibronectin-mediated adhesion. It also affects cell cycle progression of BCP-ALL cells. PTX008 is cytostatic for BP-ALL cells even when these are co-cultured with protective stroma, and can sensitize ALL cells to vincristine chemotherapy in vitro and in mice. CONCLUSIONS: PTX008 inhibits multiple functions that contribute to BP-ALL survival. The effects of Galectin-1 inhibition on both BP ALL cell proliferation and migration suggest both the leukemia cells as well as the microenvironment that protects these cells may be targeted. PMID- 29580263 TI - Post-millennial trends of socioeconomic inequalities in chronic illness among adults in Germany. AB - OBJECTIVE: Time trends in health inequalities have scarcely been studied in Germany as only few national data have been available. In this paper, we explore trends in socioeconomic inequalities in the prevalence of chronic illness using Germany-wide data from four cross-sectional health surveys conducted between 2003 and 2012 (n = 54,197; ages 25-69 years). We thereby expand a prior analysis on post-millennial inequality trends in behavioural risk factors by turning the focus to chronic illness as the outcome measure. The regression-based slope index of inequality (SII) and relative index of inequality (RII) were calculated to estimate the extent of absolute and relative socioeconomic inequalities in chronic illness, respectively. RESULTS: The results for men revealed a significant increase in the extent of socioeconomic inequalities in chronic illness between 2003 and 2012 on both the absolute and relative scales (SII2003 = 0.06, SII2012 = 0.17, p-trend = 0.013; RII2003 = 1.18, RII2012 = 1.57, p-trend = 0.013). In women, similar increases in socioeconomic inequalities in chronic illness were found (SII2003 = 0.05, SII2012 = 0.14, p-trend = 0.022; RII2003 = 1.14, RII2012 = 1.40, p-trend = 0.021). Whereas in men this trend was driven by an increasing prevalence of chronic illness in the low socioeconomic group, the trend in women was predominantly the result of a declining prevalence in the high socioeconomic group. PMID- 29580264 TI - Improving Recovery and Outcomes Every Day after the ICU (IMPROVE): study protocol for a randomized controlled trial. AB - BACKGROUND: Delirium affects nearly 70% of older adults hospitalized in the intensive care unit (ICU), and many of those will be left with persistent cognitive impairment or dementia. There are no effective and scalable recovery models to remediate ICU-acquired cognitive impairment and its attendant elevated risk for dementia or Alzheimer disease (AD). The Improving Recovery and Outcomes Every Day after the ICU (IMPROVE) trial is an ongoing clinical trial which evaluates the efficacy of a combined physical exercise and cognitive training on cognitive function among ICU survivors 50 years and older who experienced delirium during an ICU stay. This article describes the study protocol for IMPROVE. METHODS: IMPROVE is a four-arm, randomized controlled trial. Subjects will be randomized to one of four arms: cognitive training and physical exercise; cognitive control and physical exercise; cognitive training and physical exercise control; and cognitive control and physical exercise control. Facilitators administer the physical exercise and exercise control interventions in individual and small group formats by using Internet-enabled videoconference. Cognitive training and control interventions are also facilitator led using Posit Science, Inc. online modules delivered in individual and small group format directly into the participants' homes. Subjects complete cognitive assessment, mood questionnaires, physical performance batteries, and quality of life scales at baseline, 3, and 6 months. Blood samples will also be taken at baseline and 3 months to measure pro-inflammatory cytokines and acute-phase reactants; neurotrophic factors; and markers of glial dysfunction and astrocyte activation. DISCUSSION: This study is the first clinical trial to examine the efficacy of combined physical and cognitive exercise on cognitive function in older ICU survivors with delirium. The results will provide information about potential synergistic effects of a combined intervention on a range of outcomes and mechanisms of action.

PMID- 29580265 TI - Unexpected association between subclinical hearing loss and restorative sleep in a middle-aged and elderly Japanese population. AB - OBJECTIVE: Hearing loss may be associated with certain sleep abnormalities. We recently reported that subclinical hearing loss (SHL) was more prevalent in individuals in a broad Japanese population who slept longer than 8 h; however, the underlying mechanism was unknown. Therefore, we investigated the association between SHL and self-reported restorative sleep (RS), assessed by questionnaire, in a database of 33,888 Japanese aged 40-69 years without overt or diagnosed hearing loss (20,225 men, 13,663 women). RESULTS: The proportion of individuals with RS (more than half of the subjects) was significantly higher in the group with bilateral than with unilateral SHL at 4000 Hz and intact hearing; however, that was not the case at 1000 Hz, independent of age (P < 0.0001, two-way analysis of variance). Multivariate logistic regression analysis showed that bilateral SHL at 4000 Hz, but not at 1000 Hz, was significantly associated with RS. This relationship was independent of potential relevant confounders, including age, sex, and cardiometabolic risk factors. The present study extends our earlier work by revealing an unexpected association between early hearing impairment and satisfactory sleep in a middle-aged and elderly population. This association requires further confirmation regarding the possible underlying mechanism and clinical relevance. PMID- 29580266 TI - Synergistic anti-proliferative effects of combination of ABT-263 and MCL-1 selective inhibitor A-1210477 on cervical cancer cell lines. AB - OBJECTIVE: There are number of studies which report that BCL-2 anti-apoptotic proteins (e.g. BCL-2, BCL-XL, and MCL-1) are highly expressed in cervical cancer tissues compared to the normal cervical epithelia. Despite these reports, targeting these proteins for cervical cancer treatment has not been explored extensively. BH3-mimetics that inhibit specific BCL-2 anti-apoptotic proteins may hold encouraging treatment outcomes for cervical cancer management. Hence, the aim of this pilot study is to investigate the sensitivity of cervical cancer cell lines to combination of two BH3-mimetics namely ABT-263 which selectively inhibits BCL-2, BCL-XL and BCL-w and A-1210477, a selective MCL-1 inhibitor. RESULTS: We report that combination of A-1210477 and ABT-263 exhibited synergistic effects on all cervical cancer cell lines tested. Drug sensitization studies revealed that A-1210477 sensitised the cervical cancer cell lines SiHa and CaSki to ABT-263 by 11- and fivefold, respectively. Sensitization also occurred in the opposite direction whereby ABT-263 sensitised SiHa and CaSki to A 1210477 by eightfold. This report shows that combination of ABT-263 and A-1210477 could be a potential treatment strategy for cervical cancer. Extensive drug mechanistic studies and drug sensitivity studies in physiological models are necessary to unleash the prospect of this combination for cervical cancer therapy. PMID- 29580267 TI - Bevacizumab-induced intestinal perforation in a patient with inoperable breast cancer: a case report and review of the literature. AB - BACKGROUND: Gastrointestinal perforation is known as a serious adverse event, but, for breast cancer, there are very few reports of gastrointestinal perforation. This report highlights gastrointestinal perforation caused by bevacizumab for breast cancer, which is of special interest because gastrointestinal perforations caused by bevacizumab are very rare in breast cancer. CASE PRESENTATION: We describe the case of 54-year-old Japanese woman. She was diagnosed as having inoperable breast cancer T2 N1 M1 (pleura, peritoneum), Stage IV, and received chemotherapy by paclitaxel. There was reduction in the primary tumor and disappearance of the pleural effusion; however, the ascites did not change. We performed diagnostic laparoscopy which revealed that her whole peritoneum was thickened, and her small intestine, colon, and her omentum were grouped and formed an omental cake. We submitted a part of her peritoneum to pathological examination and diagnosed the peritoneum dissemination of breast cancer. On the basis of these results, paclitaxel and bevacizumab combination chemotherapy was started, and a decrease in ascites was seen. However, a gastrointestinal perforation occurred on 26th day of second cycle of bevacizumab + paclitaxel, and we performed an emergency operation. In the operation, the omental cake was resolved, and we could search the full length of the gastrointestinal tract. Two small perforations of her small intestine were seen. We performed simple closures for perforations, and peritoneal lavage and drainage. She was in a state of septic shock, but it improved. It was thought that the small intestinal perforations were caused by the bevacizumab-additional chemotherapy which was very effective. CONCLUSIONS: We report a very rare and valuable case. This case suggests that the risk of gastrointestinal perforation must be considered in a case of bevacizumab administration, and it is necessary to determine carefully the patient administered bevacizumab, regardless of the type of cancer. PMID- 29580269 TI - Comparison of an injectable toltrazuril-gleptoferron (Forceris(r)) and an oral toltrazuril (Baycox(r)) + injectable iron dextran for the control of experimentally induced piglet cystoisosporosis. AB - BACKGROUND: Cystoisospora suis causes diarrhoeal disease and reduced weight gain in suckling piglets, and a toltrazuril-based oral suspension is available for treatment. Recently a combinatorial product with toltrazuril plus iron has been developed for parenteral application. In this study we compared the efficacy of the injectable product with the oral suspension against experimentally induced piglet cystoisosporosis. METHODS: In a randomised controlled study, three groups of piglets (n = 10-13) were treated either with a fixed dose of 45 mg toltrazuril + 200 mg gleptoferron i.m. per piglet (Forceris(r)) on the second day of life (study day 2; SD 2) or with 20 mg toltrazuril/kg body weight as an oral suspension (Baycox(r) 5%) on SD 4 or left untreated (Control group). The Baycox(r) and the Control group received 200 mg of iron dextran/piglet on SD 2. All piglets were infected with 1000 sporulated C. suis oocysts on SD 3. Faecal samples were taken daily from SD 7 to SD 20 to determine faecal consistency, oocyst shedding and other diarrhoeal pathogens. Body weight was recorded on SD 1 and then weekly until SD 29. Animals were observed daily for general health and after treatment for possible adverse events. RESULTS: In the Control group all animals shed oocysts for 3.1 days on average and all animals showed diarrhoea for an average of five days. Excretion peaked on SD 9 (max. 48,618 oocysts per gram of faeces). Treatment with Forceris(r) completely suppressed oocyst excretion. In the Baycox(r) group, low levels of excretion could be detected. Diarrhoea was reduced to single piglets in the treated groups. Body weight development was reduced in the Control group compared to the treated groups. Enteropathogenic bacteria (Escherichia coli, Clostridium perfringens) could be detected. All parameters related to oocyst excretion, faecal consistency and weight gain were significantly improved in the treated groups compared to the Control group without significant differences between the treated groups. Both products were safe to use. CONCLUSIONS: Treatment with both the injectable (Forceris(r)) and the oral (Baycox(r)) formulation of toltrazuril in the prepatent period were safe and highly effective against experimental infection with C. suis in newborn piglets. PMID- 29580268 TI - The impact of direct oral anticoagulants in traumatic brain injury patients greater than 60-years-old. AB - BACKGROUND: Traumatic brain injury (TBI) is the leading cause of death among trauma patients. Patients under antithrombotic therapy (ATT) carry an increased risk for intracranial haematoma (ICH) formation. There is a paucity of data about the role of direct oral anticoagulants (DOACs) among TBI patients. METHODS: In this retrospective study, we investigated all TBI patients >=60-years-old who were admitted to the intensive care unit (ICU) from January 2014 until May 2017. Patients were grouped into those receiving vitamin K antagonists (VKA), platelet inhibitors (PI), DOACs and no antithrombotic therapy (no-ATT). RESULTS: One hundred-eighty-six, predominantly male (52.7%) TBI patients with a median age of 79 years (range: 70-85 years) were enrolled in the study. Glasgow Coma Scale and S-100beta were not different among the groups. Patients on VKA and DOACs had a higher Charlson Comorbidity Index compared to the PI group and no-ATT group (p = 0.0021). The VKA group received reversal agents significantly more often than the other groups (p < 0.0001). Haematoma progression in the follow-up cranial computed tomography (CCT) was lowest in the DOAC group. The number of CCT and surgical interventions were low with no differences between the groups. No relevant differences in ICU and hospital length of stay were observed. Mortality in the VKA group was significantly higher compared to DOAC, PI and no-ATT group (p = 0.047). DISCUSSION: Data from huge registry studies displayed higher efficacy and lower fatal bleeding rates for DOACs compared to VKAs. The current study revealed comparable results. Despite the fact that TBI patients on VKAs received reversal agents more often than patients on DOACs (84.4% vs. 24.2%, p < 0.001), mortality rate was significantly higher in the VKA group (p = 0.047). CONCLUSION: In patients >=60 years suffering from TBI, anticoagulation with DOACs appears to be safer than with VKA. Anti-thrombotic therapy with VKA resulted in a worse outcome compared to DOACs and PI. Further studies are warranted to confirm this finding. PMID- 29580270 TI - Overactive bladder induces transient hypertension. AB - OBJECTIVES: Several studies have shown the relationship between lower urinary tract symptoms and autonomic imbalance. We investigated the relationship between detrusor overactivity (DO) or urgency, and transient increase in blood pressure as a type of hypertension related to sympathetic hyperactivity. Study 1: we enrolled 14 male patients with DO and 10 without DO. We measured the overactive bladder symptom score (OABSS) and blood pressure during cystometry. Study 2: we enrolled 14 men patients with overactive bladder (OAB) and 8 without OAB. We measured OABSS and blood pressure using a 24-h ambulatory device. RESULTS: Study 1: the mean systolic pressure was significantly higher at urgency or SDV than at the other measurement points in the DO group (161.3 +/- 23.2 vs. 134.5 +/- 16.3, 137.8 +/- 15.3, or 139.5 +/- 14.8 mmHg). Study 2: the mean systolic pressure was significantly higher at the measurement points before micturition than at the points unrelated to micturition in the OAB group (159.7 +/- 24.9 vs. 124.9 +/- 13.8 mmHg). In conclusion, DO or urgency induces a transient increase of blood pressure, suggesting that OAB induces a type of hypertension before micturition. PMID- 29580271 TI - Local adaptation in European populations affected the genetics of psychiatric disorders and behavioral traits. AB - BACKGROUND: Recent studies have used genome-wide data to investigate evolutionary mechanisms related to behavioral phenotypes, identifying widespread signals of positive selection. Here, we conducted a genome-wide investigation to study whether the molecular mechanisms involved in these traits were affected by local adaptation. METHODS: We performed a polygenic risk score analysis in a sample of 2455 individuals from 23 European populations with respect to variables related to geo-climate diversity, pathogen diversity, and language phonological complexity. The analysis was adjusted for the genetic diversity of European populations to ensure that the differences detected would reflect differences in environmental exposures. RESULTS: The top finding was related to the association between winter minimum temperature and schizophrenia. Additional significant geo climate results were also observed with respect to bipolar disorder (sunny daylight), depressive symptoms (precipitation rate), major depressive disorder (precipitation rate), and subjective well-being (relative humidity). Beyond geo climate variables, we also observed findings related to pathogen diversity and language phonological complexity: openness to experience was associated with protozoan diversity; conscientiousness and extraversion were associated with language consonants. CONCLUSIONS: We report that common variation associated with psychiatric disorders and behavioral traits was affected by processes related to local adaptation in European populations. PMID- 29580272 TI - Ejaculated boar spermatozoa displaying a rare multivesicular defect. AB - Two cases of a previously unreported sperm defect appearing in boar studs in Finland are presented. Spermatozoa showed small particles scattered on their surface with a prevalence decreasing with boar age. Semen samples, either stained with eosin-nigrosin or examined with phase contrast optics on formaldehyde-fixed spermatozoa, revealed the presence of multiple particles attached to the surface of spermatozoa counted as dead cells at fixation. Transmission electron microscopy revealed these were multivesicular and multilamellar vesicles, built up by phospholipid membranes. The case is classified as a post-epididymal multivesicular sperm defect with a favorable prognosis. PMID- 29580273 TI - Effect of total exemption from medical service co-payments on potentially inappropriate medication use among elderly ambulatory patients in a single center in Japan: a retrospective cross-sectional study. AB - OBJECTIVE: The effect of total exemption from medical service co-payments on drug prescribing practices has not been extensively evaluated. We conducted a retrospective cross-sectional study to evaluate the effect of total exemption from medical service co-payments on potentially inappropriate medication (PIM) and benzodiazepine use in elderly ambulatory patients. We defined PIM based on the Beers Criteria. RESULTS: Six hundred seventy-one consecutive patients aged 65 years or older who routinely visited internal medicine physicians were included. Their mean age was 75.7 years, and 342 (51.0%) patients were men. The proportions of patients taking any PIMs or benzodiazepines were 37.7% and 16.2%, respectively. Of all patients, 62 (9.2%) were totally exempt from medical service co-payments. The patients who were totally exempt from medical service co payments showed a significantly increased risk of PIM (OR 2.16, 95% CI 1.28-3.66) or benzodiazepine use (OR 2.12, 95% CI 1.16-3.87) compared with patients who were not. These associations did not change after adjusting for age, gender, comorbidities and polypharmacy. These findings should be confirmed in other settings or hospitals in Japan. PMID- 29580274 TI - Chronic obstructive pulmonary disease (COPD): neutrophils, macrophages and lymphocytes in patients with anterior tuberculosis compared to tobacco related COPD. AB - OBJECTIVE: The inflammatory profile of chronic obstructive pulmonary disease (COPD) related to tobacco is known in certain studies while that of the post tuberculosis form is not yet known. This study aimed to evaluate the levels of neutrophils, macrophages and lymphocytes cells in sputum of COPD patients with history of smoking or anterior tuberculosis. Enumeration of cells in samples was analyzed using standard microscopy. RESULTS: We enrolled 92 participants, 46 (50%) were COPD subjects comprising 22 (47.83%) smokers and 24 (52.17%) with anterior tuberculosis while 46 (50%) healthy persons constituted the control group. The levels of neutrophils, lymphocytes and monocytes were statistically higher in COPD patients compared to the control group with p-values of 0.0001 respectively. Neutrophils levels were higher in COPD patients with history of tobacco than in COPD patients with anterior tuberculosis with a mean rate of 4.72 * 106/ml and 2.48 * 106/ml respectively (p = 0.04). The monocytes and lymphocytes levels were not statistically different between the two sub-groups of COPD patients with p-value of 0.052 and 0.91 respectively. Neutrophils are the only inflammatory cells that were significantly higher in COPD patients with history of smoking as compared to COPD patients with anterior tuberculosis. PMID- 29580275 TI - The emerging roles of exosomes in the modulation of immune responses in cancer. AB - Exosomes are promising tools for improving cancer care, but conversely may also contribute to tumor progression. Here, we highlight recently discovered roles of exosomes in modulating immune responses in cancer, with emphasis on exosomal surface proteins and on RNA and DNA content. We also discuss how exosomes could be exploited as biomarkers and delivery vehicles in cancer therapy. PMID- 29580276 TI - Indicators for prediction of Mycobacterium tuberculosis positivity detected with bronchoalveolar lavage fluid. AB - BACKGROUND: The diagnosis of active pulmonary tuberculosis (TB) remains a challenge in clinic, especially for sputum negative pulmonary TB. Bronchoalveolar lavage fluid (BALF) has higher sensitivity than sputum for detection of Mycobacterium tuberculosis (Mtb). However, bronchoscopy is invasive and costly, and not suitable for all patients. In order to make TB patients get more benefit from BALF for diagnosis, we explore which indicator might be used to optimize the choice of bronchoscopy. METHODS: A total of 1539 sputum-smear-negative pulmonary TB suspects who underwent bronchoscopy were recruited for evaluation. The sensitivity, specificity and accuracy of Mtb detection in sputum and BALF were compared. Odds ratios and 95% confidence intervals were used to assess variables that associated with positive acid-fast bacilli (AFB) smear, Mtb culture and nucleic acid amplification test (NAAT) of BALF in sputum-negative and non-sputum producing pulmonary TB suspects. RESULTS: BALF has significantly higher sensitivity (63.4%) than sputum (43.5%) for Mtb detection by culture and NAAT. 19.7% (122/620) sputum-negative and 40.0% (163/408) non-sputum-producing suspects had positive bacteriological results in BALF. Among sputum-negative and non sputum-producing pulmonary TB suspects, the positivity of Mtb detection in BALF is associated with a younger age, the presence of pulmonary cavities and a positive result of interferon-gamma release assay (IGRA). Sputum-negative patients under 35 years old with positive IGRA and pulmonary cavity had 84.8% positivity of Mtb in BALF. CONCLUSIONS: Our study indicated that combination of age, the presence of pulmonary cavity, and the result of IGRA is useful to predict the positivity of Mtb detection in BALF among sputum-negative and non sputum producing pulmonary TB suspects. Those who are under 35 years old, positive for the presence of pulmonary cavity and IGRA, should undergo bronchoscopy to collect BAFL for Mtb tests, as they have the highest possibility to get bacteriologically confirmation of TB. PMID- 29580277 TI - How to best distribute written patient education materials among patients with rheumatoid arthritis: a randomized comparison of two strategies. AB - BACKGROUND: The aim of this randomized controlled trial was to evaluate the effect of a 'supply on demand'-distribution strategy, compared to an 'unsolicited supply'-distribution strategy, on the use of a care booklet and clinical outcomes among patients with rheumatoid arthritis (RA). In addition, differences in socio demographic and clinical characteristics between users and non-users were explored. METHODS: As part of regular care the care booklet was distributed among RA-patients of two hospitals in the Netherlands. 1000 patients received the care booklet by mail, whereas another 1000 received an information letter with the option to order the care booklet. Four months after distribution, a random sample of 810 patients (stratified by hospital and distribution method) received a questionnaire on the use of the booklet, social-demographic and clinical characteristics. To compare effects between the two distribution strategies and differences between users and non-users univariate and multilevel regression analyses were performed. Secondary analysis included a per-protocol analysis (excluding participants who did not order the care booklet). RESULTS: One hundred ninety four patients in the 'unsolicited supply' and 176 patients in the 'supply on demand' group (46%) returned the questionnaire. In the 'supply on demand' group 106 (60.2%) participants ordered the care booklet. In total, no difference was found in use between the 'unsolicited supply'-group (23.2%) and the 'supply on demand'-group (21.6%) (OR 0.9 CI:0.6-1.5). However, the proportion of users among patients in the 'supply on demand'-group who ordered the booklet (35%) was significantly higher than in the 'unsolicited supply'-group (OR 1.9 CI:1.1-3.2). Regardless of distribution method, use of the care booklet was associated with being married (OR 2.4 CI:1.2-4.6), higher disease activity (mean difference 0.5 CI: 0.0-1.1), more activity limitations (mean difference 0.2 CI: 0.1-0.4), use of corticosteroids (OR 1.9 CI:1.0-3.5), perception of disease course as fluctuating (mean difference 1.4 CI:0.5-2.3) and higher educational needs (mean difference 9.7 CI: 2.9-16.6). CONCLUSIONS: From an economic and environmental perspective a 'supply on demand'-distribution strategy could be recommended. Results of this study provide starting points to optimize further implementation strategies of a care-booklet in routine care. TRIAL REGISTRATION: ISRCTN registry ( ISRCTN22703067 ). Retrospectively registered 27 March 2017. PMID- 29580278 TI - A mobile phone based tool to identify symptoms of common childhood diseases in Ghana: development and evaluation of the integrated clinical algorithm in a cross sectional study. AB - BACKGROUND: The aim of this study was the development and evaluation of an algorithm-based diagnosis-tool, applicable on mobile phones, to support guardians in providing appropriate care to sick children. METHODS: The algorithm was developed on the basis of the Integrated Management of Childhood Illness (IMCI) guidelines and evaluated at a hospital in Ghana. Two hundred and thirty-seven guardians applied the tool to assess their child's symptoms. Data recorded by the tool and health records completed by a physician were compared in terms of symptom detection, disease assessment and treatment recommendation. To compare both assessments, Kappa statistics and predictive values were calculated. RESULTS: The tool detected the symptoms of cough, fever, diarrhoea and vomiting with good agreement to the physicians' findings (kappa = 0.64; 0.59; 0.57 and 0.42 respectively). The disease assessment barely coincided with the physicians' findings. The tool's treatment recommendation correlated with the physicians' assessments in 93 out of 237 cases (39.2% agreement, kappa = 0.11), but underestimated a child's condition in only seven cases (3.0%). CONCLUSIONS: The algorithm-based tool achieved reliable symptom detection and treatment recommendations were administered conformably to the physicians' assessment. Testing in domestic environment is envisaged. PMID- 29580279 TI - Distinct clinical characteristics and helminth co-infections in adult tuberculosis patients from urban compared to rural Tanzania. AB - BACKGROUND: Differences in rural and urban settings could account for distinct characteristics in the epidemiology of tuberculosis (TB). We comparatively studied epidemiological features of TB and helminth co-infections in adult patients from rural and urban settings of Tanzania. METHODS: Adult patients (>= 18 years) with microbiologically confirmed pulmonary TB were consecutively enrolled into two cohorts in Dar es Salaam, with ~ 4.4 million inhabitants (urban), and Ifakara in the sparsely populated Kilombero District with ~ 400 000 inhabitants (rural). Clinical data were obtained at recruitment. Stool and urine samples were subjected to diagnose helminthiases using Kato-Katz, Baermann, urine filtration, and circulating cathodic antigen tests. Differences between groups were assessed by chi2, Fisher's exact, and Wilcoxon rank sum tests. Logistic regression models were used to determine associations. RESULTS: Between August 2015 and February 2017, 668 patients were enrolled, 460 (68.9%) at the urban and 208 (31.1%) at the rural site. Median patient age was 35 years (interquartile range [IQR]: 27-41.5 years), and 454 (68%) were males. Patients from the rural setting were older (median age 37 years vs. 34 years, P = 0.003), had a lower median body mass index (17.5 kg/m2 vs. 18.5 kg/m2, P < 0.001), a higher proportion of recurrent TB cases (9% vs. 1%, P < 0.001), and in HIV/TB co infected patients a lower median CD4 cell counts (147 cells/MUl vs. 249 cells/MUl, P = 0.02) compared to those from urban Tanzania. There was no significant difference in frequencies of HIV infection, diabetes mellitus, and haemoglobin concentration levels between the two settings. The overall prevalence of helminth co-infections was 22.9% (95% confidence interval [CI]: 20.4-27.0%). The significantly higher prevalence of helminth infections at the urban site (25.7% vs. 17.3%, P = 0.018) was predominantly driven by Strongyloides stercoralis (17.0% vs. 4.8%, P < 0.001) and Schistosoma mansoni infection (4.1% vs. 16.4%, P < 0.001). Recurrent TB was associated with living in a rural setting (adjusted odds ratio [aOR]: 3.97, 95% CI: 1.16-13.67) and increasing age (aOR: 1.06, 95% CI: 1.02-1.10). CONCLUSIONS: Clinical characteristics and helminth co-infections pattern differ in TB patients in urban and rural Tanzania. The differences underline the need for setting-specific, tailored public health interventions to improve clinical management of TB and comorbidities. PMID- 29580280 TI - Report of the first international workshop on onchocerciasis-associated epilepsy. AB - BACKGROUND: Recently, several epidemiological studies performed in Onchocerca volvulus-endemic regions have suggested that onchocerciasis-associated epilepsy (OAE) may constitute an important but neglected public health problem in many countries where onchocerciasis is still endemic. MAIN TEXT: On October 12-14th 2017, the first international workshop on onchocerciasis-associated epilepsy (OAE) was held in Antwerp, Belgium. The workshop was attended by 79 participants from 20 different countries. Recent research findings strongly suggest that O. volvulus is an important contributor to epilepsy, particularly in meso- and hyperendemic areas for onchocerciasis. Infection with O. volvulus is associated with a spectrum of epileptic seizures, mainly generalised tonic-clonic seizures but also atonic neck seizures (nodding), and stunted growth. OAE is characterised by an onset of seizures between the ages of 3-18 years. Multidisciplinary working groups discussed topics such as how to 1) strengthen the evidence for an association between onchocerciasis and epilepsy, 2) determine the burden of disease caused by OAE, 3) prevent OAE, 4) improve the treatment/care for persons with OAE and affected families, 5) identify the pathophysiological mechanism of OAE, and 6) deal with misconceptions, stigma, discrimination and gender violence associated with OAE. An OAE Alliance was created to increase awareness about OAE and its public health importance, stimulate research and disseminate research findings, and create partnerships between OAE researchers, communities, advocacy groups, ministries of health, non-governmental organisations, the pharmaceutical industry and funding organizations. CONCLUSIONS: Although the exact pathophysiological mechanism underlying OAE remains unknown, there is increasing evidence that by controlling and eliminating onchocerciasis, OAE will also disappear. Therefore, OAE constitutes an additional argument for strengthening onchocerciasis elimination efforts. Given the high numbers of people with epilepsy in O. volvulus-endemic regions, more advocacy is urgently needed to provide anti-epileptic treatment to improve the quality of life of these individuals and their families. PMID- 29580281 TI - A retrospective review of 146 active and passive fixation bradycardia lead implantations in 74 dogs undergoing pacemaker implantation in a research setting of short term duration. AB - BACKGROUND: Canine veterinary patients increasingly benefit from implantation of transvenous pacemakers for bradyarrhythmias. No published data exist examining procedural outcomes of pacemaker implantation performed in the preclinical laboratory. The purpose was to review short term complication, infection, dislodgement, penetration rates, plus overall morbidity following pacemaker implantation in the research setting. A retrospective review of 74 Class A purpose-bred mongrels implanted with active (n = 89) and passive fixation (n = 57) intracardiac leads for dual (n = 72) or single (n = 2) chamber pacing was performed. RESULTS: All leads were implanted successfully, meeting electrical implant criteria. Follow-ups typically occurred every 7 days (first month), then at 30 day intervals. Seroma formation was 1.4% and 10.8% at the venotomy and pulse generator site respectively. Overall infection rate was 1.4%. Overall dislodgement rate was 2.1%, (2 passive atrial leads, 1 passive ventricular lead). Overall fractures and insulation defects were zero. Two helix penetrations were noted incidentally post mortem, one at the right atrial appendage and one at the right ventricle (64 dogs, 128 leads evaluated), a 1.6% event rate. Major in-life adverse events were 5.4% (4 of 74 dogs), including 1 infection and 3 lead dislodgements. CONCLUSIONS: This review demonstrates a low complication rate with bradycardia lead implants in the short term (up to 180 days), in a high volume research setting. Lead type, implant technique, surgeon experience, healthy patient population, patient size and follow-up care play a role. This review also suggests active fixation leads in the right atrial appendage of dogs are safe and reliable. PMID- 29580282 TI - Plasma YKL-40 and NGAL are useful in distinguishing ACO from asthma and COPD. AB - BACKGROUND: Asthma-chronic obstructive pulmonary disorder (COPD) overlap (ACO) is characterized by the coexistence of features of both asthma and COPD and is associated with rapid progress and a poor prognosis. Thus, the early recognition of ACO is crucial. OBJECTIVES: We sought to explore the plasma levels of biomarkers associated with asthma (periostin, TSLP and YKL-40), COPD (NGAL) and their possible correlation with lung function, the bronchodilator response and radiographic imaging in patients with asthma, COPD and with features of ACO. METHODS: We enrolled 423 subjects from 6 clinical centers. All participants underwent blood collection, lung function measurements, bronchodilator response tests and high-resolution CT. Correlations of the plasma biomarkers with lung function, the bronchodilator response and percentemphysema were calculated by Spearman's rank correlation and multivariate stepwise regressionanalysis. RESULTS: 1) Patients with features of ACO had lower plasma YKL-40 than COPD patients and a moderate elevated plasma level of NGAL compared with asthma patients. 2) Patients with features of ACO had an intermediate degree of airflow obstruction, the bronchodilator response and emphysema between patients with COPD and asthma. 3) Plasma YKL-40 was negatively correlated with lung function and with the bronchodilator response, and plasma NGAL was positively correlated with the extent of emphysema. CONCLUSIONS: Plasma YKL-40 is a promising candidate for distinguishing between patients with features of ACO and COPD patients, while plasma NGAL may be a valuable biomarker for differentiating between patients with features of ACO and asthma patients. CLINICAL TRIAL REGISTRATION: ChiCTR-OOC 16009221. PMID- 29580283 TI - Prevalence and reasons for intentional use of complementary and alternative medicine as an adjunct to future visits to a medical doctor for chronic disease. AB - BACKGROUND: Intentional use of complementary and alternative medicine (CAM) has previously only been researched in small, possibly biased, samples. There seems to be a lack of scientific information regarding healthy individual's attitudes and presumed use of CAM. The aim of this study is to describe prevalence and characteristics of participants who intend to see a CAM provider compared to participants who intend to see a medical doctor (MD) only when suffering from a chronic, non- life-threatening disease and in the need of treatment. Further to describe differences between the groups regarding expected reasons for CAM use and expected skills of CAM providers. METHOD: The survey was conducted in January 2016 as part of the "TNS Gallup Health policy Barometer". In total, 1728 individuals aged 16-92 years participated in the study, constituting an overall response rate of 47%. The survey included questions regarding opinions and attitudes towards health, health services and health politics in Norway. RESULTS: The majority of the participants (90.2%) would see a MD only if they were suffering from a chronic, non- life-threatening disease and were in the need of treatment. Men over the age of 60 with a university education tended to see a MD only. Only 9.8% of all respondents would in addition visit a CAM provider. Being an intentional user of a MD + CAM provider was associated with being a woman under the age of 60. The respondents believed that CAM providers have professional competence based on formal training in CAM. They also believed that individuals seeing a CAM provider have poor health and are driven by the hope of being cured. Further, that they have heard that others have good experience with such treatment. CONCLUSION: Intentional use of CAM is associated with positive attitudes, trustworthiness, and presumed positive experiences in the CAM-patient setting. Intentional CAM users also have the impression that CAM providers have professional competence based on formal training in alternative therapies. PMID- 29580284 TI - The development of facility standards for common outpatient procedures and implications for the context of abortion. AB - BACKGROUND: In recent years, an increasing number of states have enacted laws that impose specific requirements for facilities in which abortions are performed. In this study, we sought to understand the processes used to develop facility standards in the context of other, less politically charged areas of health care and consider implications for the context of abortion. METHODS: We conducted key informant interviews with 20 clinicians and accreditation professionals involved in facility standards development for common outpatient procedures (endoscopy, gynecology, oral surgery, plastic surgery). We examined the motivations for and processes used in facility standards development, use of scientific evidence in standards development, and decision-making in the absence of evidence. Interview data were thematically coded and analyzed using an iterative approach. RESULTS: In contrast to U.S. state laws that target abortion facilities, standards for other outpatient procedures are commonly set by committees of clinicians organized by professional associations or accreditation organizations. These committees seek to establish standards that ensure patient safety without placing unnecessary burden on clinicians in practice. They aim to create evidence-based standards but can be hampered by lack of relevant research. In the absence of research evidence, committees rely on their clinical expertise and sense of best practices in decision-making. According to respondents, considerations of potential harm (e.g., deeper levels of sedation, invasiveness), rather than the specific procedure, should prompt additional requirements. CONCLUSIONS: If facility standards in the context of abortion were developed through processes similar to other outpatient procedures, 1) professionals who perform the procedure would be involved in standards development and 2) in the absence of clear research evidence, the expertise of clinicians, and the guidelines and standards of other organizations, are used to describe a best practice standard of care. PMID- 29580285 TI - Pioglitazone is effective for multiple phenotyepes of the Zucker fa/fa rat with polycystc ovary morphology and insulin resistance. AB - BACKGROUND: Hyperandrogenism and insulin resistance may be related to the etiology of PCOS. Zucker fa/fa rats with polycystic ovary are obese, have insulin resistance without diabetes mellitus or hyperandrogenism and can be utilized as PCOS model rats without effects of hyperandrogenemia. PCOS patients are reported to have elevated levels of serum anti-Mullerian hormone (AMH), which has an inhibitory action on folliculogenesis, and low levels of serum adiponectin, which blocks apoptosis and induces biological effects in some tissues. Pioglitazone, an insulin sensitizer, is administered to PCOS patients with insulin resistance to induce ovulation but the mechanisms by which this occurs have not been elucidated. METHODS: We purchased 4-week-old female fatty Zucker fa/fa rats as well as lean Zucker +/+ rats for use as control rats with normal insulin sensitivity. The Zucker fa/fa rats were administered pioglitazone (2.5 mg/kg body weight/day) or a vehicle every day for 14 days in separate groups. The Zucker +/+ rats were also administered the vehicle. After 2 weeks of treatment, they were euthanized and we obtained serum samples and both ovaries and determined the body weight, ovarian weight, and serum AMH, adiponectin, testosterone, and androstenedione levels. We also examined ovarian histology to check follicle numbers by using hematoxylin-eosin staining, and the number of atretic follicles using Tdt-mediated dUTP nick end labeling (TUNEL) methods. RESULTS: The Zucker fa/fa rats used as PCO model rats and Pioglitazone treated PCO model rats were significantly heavier than the Zucker +/+ control rats (p < 0.05) at 15 day old. Pioglitazone treatment did not influence body weight or ovarian weight in either group. However, the total number of follicles was significantly larger in the PCO model rats than in the control rats (P < 0.05). Although pioglitazone treatment appeared to decrease the total number of follicles in the PCO model rats, the decrease was not statistically significant. However, pioglitazone treatment significantly decreased the total number of atretic follicles and the rate of atreteic follicles in the PCO model rats (P < 0.05). The serum AMH level was significantly higher in the PCO model rats than in the control rats. Pioglitazone treatment significantly decreased the serum AMH level and significantly increased the serum adiponectin level in the PCO model rats (P < 0.05). Serum testosterone and androstenedione levels were quite low or undetectable in the 3 groups of rats, and were not influenced by pioglitazone treatment. CONCLUSION: In this study, pioglitazone treatment reduced the serum AMH level and increased the serum adiponectin level in PCO model rats. These effects are related to reduction of the total number of atretic follicles and rate of atretic follicles. This proves that pioglitazone treatment improves healthy follicle growth in these PCO model rats with insulin resistance. PMID- 29580286 TI - Hematoma block or procedural sedation and analgesia, which is the most effective method of anesthesia in reduction of displaced distal radius fracture? AB - BACKGROUND: Procedure sedation and analgesia (PSA) is often used to alleviate discomfort and to facilitate fracture reduction for patients with distal radius fracture in emergency departments and clinics, but risks of respiratory distress and needs for different levels of monitoring under PSA are still under concern. Hematoma block (HB) is a simple alternative method of providing rapid pain relief during reduction of distal radius fracture. However, there is still in lack of strong evidence to promote HB over PSA in clinical practice. The aim of this study was to compare HB and PSA for adult and pediatric patients during reduction of displaced distal radius fracture to identify the level of pain relief, frequency of adverse effects (AEs), and reduction failure. METHODS: The PubMed, ScienceDirect, Cochrane Library, and ClinicalTrials.gov were searched for studies comparing HB or PSA in distal radius fracture reduction. The search revealed four randomized controlled trials and one non-randomized trial, which included two studies of pediatric subjects and three studies of adult subjects. Subgroup meta analysis for adult and pediatric groups were specifically performed according to age difference to avoid potential bias. RESULTS: In the adult group, the effect of HB on post-reduction pain severity was better than that of PSA with significant heterogeneity (Hedges' g - 0.600, 95% confidence interval (CI) - 1.170 to - 0.029, p = 0.039), although there was no difference on the pain severity during reduction between these two groups with significant heterogeneity (Hedges' g 0.356, 95% CI - 1.101 to 1.812, p = 0.632). In the pediatric group, the treatment effect on pain severity was significantly better by HB than that by PSA but without significant heterogeneity (Hedges' g - 0.402, 95% CI - 0.718 to - 0.085, p = 0.013, I 2 < 0.001%). Most of the reported adverse effects (AEs) include nausea, vomiting, and respiratory distress developed in adult patients treated by PSA. The rates of reported AEs did not significantly differ between HB and PSA in the pediatric group. Additionally, final outcomes of reduction failure did not significantly differ between HB and PSA in both adult and pediatric groups. CONCLUSION: Hematoma block is a safe and effective alternative of anesthesia in reduction of distal radius fracture without inferior pain relief compared with PSA among adult and pediatric patients. PMID- 29580287 TI - How I do it: feasibility of a new ultrasound probe fixator to facilitate high quality stress echocardiography. AB - BACKGROUND: Stress echocardiography (SE) has recently regained momentum as an important diagnostic tool for the assessment of both ischemic and non-ischemic heart disease. Performing SE during physical exercise is challenging due to a suboptimal patient position and vigorous movements of the patient's chest. This hampers a stable ultrasound position and reduces the diagnostic performance of SE. A stable ultrasound probe position would facilitate producing high quality images during continuous measurements. With Probefix (Usono, Eindhoven, The Netherlands), a newly developed tool to fixate the ultrasound probe to the patient's chest, stabilization of the probe during physical exercise is possible. IMPLEMENTATION AND RESULTS: The technique of SE with the Probefix and its' feasibility are evaluated in a small pilot study. Probefix fixates the ultrasound probe to the patient's chest, using two chest straps and a fixation device. The ultrasound probe position and angle may be altered with a relative high degree of freedom. We tested the Probefix for continuous echocardiographic imaging in 12 study subjects during supine and upright ergometer stress tests. One patient was unable to perform exercise and in two study subjects good quality images were not achieved. In the other patients (82%) a stable probe position was obtained, with subsequent good quality echocardiographic images during SE. CONCLUSION: We have demonstrated the feasibility of the Probefix support during ergometer tests in supine and upright positions and conclude that this external fixator may facilitate continuous monitoring of cardiac function in a group of patients. PMID- 29580288 TI - Modulating PD-L1 expression in multiple myeloma: an alternative strategy to target the PD-1/PD-L1 pathway. AB - Even with recent advances in therapy regimen, multiple myeloma patients commonly develop drug resistance and relapse. The relevance of targeting the PD-1/PD-L1 axis has been demonstrated in pre-clinical models. Monotherapy with PD-1 inhibitors produced disappointing results, but combinations with other drugs used in the treatment of multiple myeloma seemed promising, and clinical trials are ongoing. However, there have recently been concerns about the safety of PD-1 and PD-L1 inhibitors combined with immunomodulators in the treatment of multiple myeloma, and several trials have been suspended. There is therefore a need for alternative combinations of drugs or different approaches to target this pathway. Protein expression of PD-L1 on cancer cells, including in multiple myeloma, has been associated with intrinsic aggressive features independent of immune evasion mechanisms, thereby providing a rationale for the adoption of new strategies directly targeting PD-L1 protein expression. Drugs modulating the transcriptional and post-transcriptional regulation of PD-L1 could represent new therapeutic strategies for the treatment of multiple myeloma, help potentiate the action of other drugs or be combined to PD-1/PD-L1 inhibitors in order to avoid the potentially problematic combination with immunomodulators. This review will focus on the pathophysiology of PD-L1 expression in multiple myeloma and drugs that have been shown to modulate this expression. PMID- 29580289 TI - A multi-host approach to identify a transposon mutant of Pseudomonas aeruginosa LESB58 lacking full virulence. AB - OBJECTIVE: Pseudomonas aeruginosa is an opportunistic bacterial pathogen well known to cause chronic lung infections in individuals with cystic fibrosis (CF). Some strains adapted to this particular niche show distinct phenotypes, such as biofilm hyperproduction. It is necessary to study CF clinical P. aeruginosa isolates, such as Liverpool Epidemic Strains (LES), to acquire a better understanding of the key genes essential for in vivo maintenance and the major virulence mechanisms involved in CF lung infections. Previously, a library of 9216 mutants of the LESB58 strain were generated by signature-tagged mutagenesis (STM) and screened in the rat model of chronic lung infection, allowing the identification of 163 STM mutants showing defects in in vivo maintenance. RESULTS: In the present study, these 163 mutants were successively screened in two additional surrogate host models (the amoeba and the fruit fly). The STM PALES_11731 mutant was the unique non-virulent in the three hosts. A competitive index study in rat lungs confirmed that the mutant was 20-fold less virulent than the wild-type strain. This study demonstrated the pertinence to use a multi-host approach to study the genetic determinants of P. aeruginosa strains infecting CF patients. PMID- 29580290 TI - Rescue of an aggressive female sexual courtship in mice by CRISPR/Cas9 secondary mutation in vivo. AB - OBJECTIVE: We had previously reported a mouse line carrying the Atypical female courtship (HoxD Afc ) allele, where an ectopic accumulation of Hoxd10 transcripts was observed in a sparse population of cells in the adult isocortex, as a result of a partial deletion of the HoxD gene cluster. Female mice carrying this allele displayed an exacerbated paracopulatory behavior, culminating in a severe mutilation of the studs' external genitals. To unequivocally demonstrate that this intriguing phenotype was indeed caused by an illegitimate function of the HOXD10 protein, we use CRISPR/Cas9 technology to induce a microdeletion into the homeobox of the Hoxd10 gene in cis with the HoxD Afc allele. RESULTS: Females carrying this novel HoxDDel(1-9)d10hd allele no longer mutilate males. We conclude that a brain malfunction leading to a severe pathological behavior can be caused by the mere binding to DNA of a transcription factor expressed ectopically. We also show that in HoxD Afc mice, Hoxd10 was expressed in cells containing glutamate decarboxylase (Gad1) and Cholecystokinin (Cck) transcripts, corroborating our proposal that a small fraction of GABAergic neurons in adult hippocampus may participate to some aspects of female courtship.

AB - Orthogonal CRISPR-Cas systems have been integrated into combinatorial screens to decipher complex genetic relationships in two recent studies. PMID- 29580292 TI - Hermansky-Pudlak syndrome type 2 manifests with fibrosing lung disease early in childhood. AB - BACKGROUND: Hermansky-Pudlak syndrome (HPS), a hereditary multisystem disorder with oculocutaneous albinism, may be caused by mutations in one of at least 10 separate genes. The HPS-2 subtype is distinguished by the presence of neutropenia and knowledge of its pulmonary phenotype in children is scarce. METHODS: Six children with genetically proven HPS-2 presented to the chILD-EU register between 2009 and 2017; the data were collected systematically and imaging studies were scored blinded. RESULTS: Pulmonary symptoms including dyspnea, coughing, need for oxygen, and clubbing started 3.3 years before the diagnosis was made at the mean age of 8.83 years (range 2-15). All children had recurrent pulmonary infections, 3 had a spontaneous pneumothorax, and 4 developed scoliosis. The frequency of pulmonary complaints increased over time. The leading radiographic pattern was ground-glass opacities with a rapid increase in reticular pattern and traction bronchiectasis between initial and follow-up Computer tomography (CT) in all subjects. Honeycombing and cysts were newly detectable in 3 patients. Half of the patients received a lung biopsy for diagnosis; histological patterns were cellular non-specific interstitial pneumonia, usual interstitial pneumonia-like, and desquamative interstitial pneumonia. CONCLUSIONS: HPS-2 is characterized by a rapidly fibrosing lung disease during early childhood. Effective treatments are required. PMID- 29580293 TI - Effects of oncological care pathways in primary and secondary care on patient, professional, and health systems outcomes: protocol for a systematic review and meta-analysis. AB - BACKGROUND: The high impact of a cancer diagnosis on patients and their families and the increasing costs of cancer treatment call for optimal and efficient oncological care. To improve the quality of care and to minimize healthcare costs and its economic burden, many healthcare organizations introduce care pathways to improve efficiency across the continuum of cancer care. However, there is limited research on the effects of cancer care pathways in different settings. METHODS: The aim of this systematic review and meta-analysis described in this protocol is to synthesize existing literature on the effects of oncological care pathways. We will conduct a systematic search strategy to identify all relevant literature in several biomedical databases, including Cochrane library, MEDLINE, Embase, and CINAHL. We will follow the methodology of Cochrane Effective Practice and Organisation of Care (EPOC), and we will include randomized trials, non randomized trials, controlled before-after studies, and interrupted time series studies. In addition, we will include full economic evaluations (cost effectiveness analyses, cost-utility analyses, and cost-benefit analyses), cost analyses, and comparative resource utilization studies, if available. Two reviewers will independently screen all studies and evaluate those included for risk of bias. From these studies, we will extract data regarding patient, professional, and health systems outcomes. Our systematic review will follow the PRISMA set of items for reporting in systematic reviews and meta-analyses. DISCUSSION: Following the protocol outlined in this article, we aim to identify, assess, and synthesize all available evidence in order to provide an evidence base on the effects of oncological care pathways as reported in the literature.

AB - BACKGROUND: Giardia duodenalis and Enterocytozoon bieneusi are widespread pathogens that can infect humans and various animal species. Thus far, there are only a few reports of G. duodenalis and E. bieneusi infections in ruminant wildlife. Thus, the objective of this study was to examine the prevalence of G. duodenalis and E. bieneusi in forest musk deer in Sichuan, China, as well as identifying their genotypes. RESULTS: In total, we collected 223 faecal samples from musk deer at the Sichuan Institute of Musk Deer Breeding in Dujiangyan (n = 80) and the Maerkang Breeding Institute (n = 143). Five (2.24%) faecal samples were positive for G. duodenalis; three belonged to assemblage E, and two belonged to assemblage A based on the sequence analysis of the beta-giardin (bg) gene. One sample each was found to be positive based on the glutamate dehydrogenase (gdh) and triosephosphate isomerase (tpi) gene, respectively. Thirty-eight (17.04%) faecal samples were found to be E. bieneusi-positive based on the internal transcribed spacer (ITS) sequence, and only SC03 genotype was identified, which belonged to the zoonotic group 1 according to the phylogenic analysis. The infection rates were significantly different among the different geographical areas and age groups but had no apparent association with gender or clinical symptoms. CONCLUSIONS: To our knowledge, this was the first molecular characterisation of G. duodenalis and E. bieneusi in musk deer. Identification of the zoonotic genotypes indicated a potential public health threat, and our study suggested that the forest musk deer is an important carrier of these parasites.

AB - BACKGROUND: As leprosy elimination becomes an increasingly realistic goal, it is essential to determine the factors that contribute to its persistence. We evaluate social and economic factors as predictors of leprosy annual new case detection rates within India, where the majority of leprosy cases occur. METHODS: We used correlation and linear mixed effect regressions to assess whether poverty, illiteracy, nighttime satellite radiance (an index of development), and other covariates can explain district-wise annual new case detection rate and Grade 2 disability diagnoses. RESULTS: We find only weak evidence of an association between poverty and annual new case detection rates at the district level, though illiteracy and satellite radiance are statistically significant predictors of leprosy at the district level. We find no evidence of rapid decline over the period 2008-2015 in either new case detection or new Grade 2 disability. CONCLUSIONS: Our findings suggest a somewhat higher rate of leprosy detection, on average, in poorer districts; the overall effect is weak. The divide between leprosy case detection and true incidence of clinical leprosy complicates these results, particularly given that the detection rate is likely disproportionately lower in impoverished settings. Additional information is needed to distinguish the determinants of leprosy case detection and transmission during the elimination epoch. PMID- 29580297 TI - Clinical impact of "pure" empirical catheter ablation of slow-pathway in patients with non-ECG documented clinical on-off tachycardia. AB - BACKGROUND: Catheter ablation of slow-pathway (CaSP) has been reported to be effective in patients with dual atrioventricular nodal conduction properties (dcp AVN) and clinical ECG documentation but without the induction of tachycardia during electrophysiological studies (EPS). However, it is unknown whether CaSP is beneficial in the absence of pre-procedural ECG documentation and without the induction of tachycardia during EPS. The aim of this study was to evaluate long term results after a "pure" empirical CaSP (peCaSP). METHODS: 334 consecutive patients who underwent CaSP (91 male, 47.5 +/- 17.6 years) were included in this study. Sixty-three patients (19%) who had no pre-procedural ECG documentation, and demonstrated dcp-AVN with a maximum of one echo-beat were assigned to the peCaSP group. The remaining 271 patients (81%) were assigned to the standard CaSP group (stCaSP). Clinical outcomes of the two groups were compared, based on ECG documented recurrence or absence of tachycardia and patients' recorded symptoms. RESULTS: CaSP was performed in all patients without any major complications including atrioventricular block. During follow-up (909 +/- 435 days), 258 patients (77%) reported complete cessation of clinical symptoms. There was no statistically significant difference in the incidence of AVNRT recurrence between the peCaSP and stCaSP groups (1/63 [1.6%] vs 3/271 [1.1%], P = 0.75). Complete cessation of clinical symptoms was noted significantly less frequently in patients after peCaSP (39/63 [62%] vs 219/271 [81%], P = 0.0013). The incidence of non-AVNRT atrial tachyarrhythmias (AT) was significantly higher in patients after peCaSP (5/63 [7.9%] vs 1/271 [0.4%], P = 0.0011). CONCLUSION: A higher incidence of other AT and subjective symptom persistence are demonstrated after peCaSP, while peCaSP improves clinical symptoms in 60% of patients with non documented on-off tachycardia. PMID- 29580298 TI - Submental liposuction for the management of lymphedema following head and neck cancer treatment: a randomized controlled trial. AB - BACKGROUND: Patients who have undergone treatment for head and neck cancer are at risk for neck lymphedema, which can severely affect quality of life. Liposuction has been used successfully in cancer patients who suffer from post-treatment limb lymphedema. The purpose of our study was to review the outcomes of head and neck cancer patients at our center who have undergone submental liposuction for post treatment lymphedema and compare their subsequent results with a control group. METHODS: All head and neck cancer patients at an oncology center in tertiary hospital setting who complained to their attending surgeon or radiation oncologist regarding cervical lymphedema secondary to head and neck cancer treatment, and had been disease-free for a minimum of one year, with no previous facial plastic surgical procedures were eligible for inclusion into the study. Study design was a non-blinded randomized controlled trial. Twenty patients were randomized into a treatment arm (underwent submental liposuction n = 10) and control arm (n = 10). Both groups of patients completed two surveys (Modified Blepharoplasty Outcome Evaluation and the validated Derriford Appearance Scale) on initial office visit after consenting for the trial. The treatment group then completed the surveys 6 months post-operatively while the control group filled the surveys 6 months after the initial assessment but had no intervention. Mann Whitney U tests were performed to compare the responses of those that did and did not receive liposuction. RESULTS: Our study demonstrated a statistically significant improvement in patients' self-perception of appearance and statistically significant subjective scoring of appearance following submental liposuction. CONCLUSIONS: Submental liposuction is an effective and safe procedure to improves the quality of life for head and neck cancer patients suffering from post-treatment lymphedema. PMID- 29580299 TI - A Systematic Review of the Burden of Multidrug-Resistant Healthcare-Associated Infections Among Intensive Care Unit Patients in Southeast Asia: The Rise of Multidrug-Resistant Acinetobacter baumannii. AB - OBJECTIVETo summarize the clinical burden (cumulative incidence, prevalence, case fatality rate and length of stay) and economic burden (healthcare cost) of healthcare-associated infections (HAIs) due to multidrug-resistant organisms (MDROs) among patients in intensive care units (ICUs) in Southeast Asia.DESIGNSystematic review.METHODSWe conducted a comprehensive literature search in PubMed, EMBASE, CINAHL, EconLit, and the Cochrane Library databases from their inception through September 30, 2016. Clinical and economic burdens and study quality were assessed for each included study.RESULTSIn total, 41 studies met our inclusion criteria; together, 22,876 ICU patients from 7 Southeast Asian countries were included. The cumulative incidence of HAI caused by A. baumannii (AB) in Southeast Asia is substantially higher than has been reported in other regions, especially carbapenem-resistant AB (CRAB; 64.91%) and multidrug-resistant AB (MDR-AB) (58.51%). Evidence of a dose-response relationship between different degrees of drug resistance and excess mortality due to AB infections was observed. Adjusted odds ratios were 1.23 (95% confidence interval [CI], 0.51-3.00) for MDR-AB, 1.72 (95% CI, 0.77-3.80) for extensively drug-resistant AB (XDR-AB), and 1.82 (95% CI, 0.55-6.00) for pandrug-resistant AB (PDR-AB). There is, however, a paucity of published data on additional length of stay and costs attributable to MDROs.CONCLUSIONSThis review highlights the challenges in addressing MDROs in Southeast Asia, where HAIs caused by MDR gram negative bacteria are abundant and have a strong impact on society. With our findings, we hope to draw the attention of clinicians and policy makers to the problem of antibiotic resistance and to issue a call for action in the management of MDROs.Infect Control Hosp Epidemiol 2018;39:525-533. PMID- 29580300 TI - Association study highlights the influence of ELOVL fatty acid elongase 6 gene region on backfat fatty acid composition in Large White pig breed. AB - Dietary fatty acid (FA) composition has an impact on human health. There is an increasing request from consumers for healthier food and pork industry must respond to it without worsening performance and the technological properties of pork products. The inclusion of genetic markers for carcass FA composition in pig selection schemes could be a useful tool to reach the right balance between unsaturated and saturated FAs to satisfy market demands. With the aim of finding genomic regions associated with porcine backfat FA composition, a genome-wide association study was performed on 798 Italian Large White pigs genotyped using Illumina PorcineSNP60 k. The strongest associations with backfat contents of palmitic, palmitoleic, oleic, medium-chain and long-chain FAs were found for the Sus scrofa chromosome (SSC) 8 region located at 119 to 122 Mb, where the gene ELOVL FA elongase 6 is mapped. Palmitic, palmitoleic, stearic and oleic acid contents were also found associated with SSC14, in particular with the genomic region at 121 to 124 Mb, where stearoyl-CoA desaturase Delta9 gene lies. On the other hand, the genomic regions associated with backfat contents of arachidic, arachidonic, n-6 and n-3 FAs showed to harbour mainly genes involved in dietary lipids and carbohydrates digestion, absorption and utilisation. To our knowledge, this is the first study performed in Large White pigs identifying markers and genomic regions associated with backfat FA composition. The results validate in Large White some associations previously detected in other pig breeds and indicate the involvement of distinct metabolic pathways in the deposition pattern of essential and non-essential FAs.

AB - : AimThe objective of this study was to assess determinants of poor sleep quality which is an under-diagnosed and under-treated problem in elderly patients with diabetes mellitus, hyperlipidemia and hypertension. BACKGROUND: Poor sleep quality is linked to decreased quality of life, increased morbidity and mortality. Poor sleep quality is common in the elderly population with associated cardiometabolic risk factors such as diabetes, hyperlipidemia and hypertension. METHODS: This is a cross-sectional study undertaken in the primary healthcare setting (Singhealth Polyclinics-Outram) in Singapore. Singaporeans aged 65 years and above who had at least one of the three cardiometabolic risk factors (diabetes, hypertension and hyperlipidemia) were identified. Responders' sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and were divided into those with good quality sleep and those with poor quality sleep, based on the PSQI score. Information on demographics, co morbidities and lifestyle practices were collected. Descriptive and multivariate analyses of determinants of poor sleep were determined.FindingsThere were 199 responders (response rate 88.1%). Nocturia (adjusted prevalence rate ratio 1.54, 95% confidence interval 1.06-2.26) was found to be associated with an increased risk of poor sleep quality in elderly patients with diabetes mellitus, hypertension and hyperlipidaemia. Nocturia, a prevalent problem in the Asian elderly population, has been found to be associated with poor sleep quality in our study. Hence, it is imperative to identify and treat patients with nocturia to improve sleep quality among them. PMID- 29580301 TI - Changes in the nutritional quality of fast-food items marketed at restaurants, 2010 v. 2013. AB - OBJECTIVE: To examine the nutritional quality of menu items promoted in four (US) fast-food restaurant chains (McDonald's, Burger King, Wendy's, Taco Bell) in 2010 and 2013. DESIGN: Menu items pictured on signs and menu boards were recorded at 400 fast-food restaurants across the USA. The Nutrient Profile Index (NPI) was used to calculate overall nutrition scores for items (higher scores indicate greater nutritional quality) and was dichotomized to denote healthier v. less healthy items. Changes over time in NPI scores and energy of promoted foods and beverages were analysed using linear regression. SETTING: Four hundred fast-food restaurants (McDonald's, Burger King, Wendy's, Taco Bell; 100 locations per chain). SUBJECTS: NPI of fast-food items marketed at fast-food restaurants. RESULTS: Promoted foods and beverages on general menu boards and signs remained below the 'healthier' cut-off at both time points. On general menu boards, pictured items became modestly healthier from 2010 to 2013, increasing (mean (se)) by 3.08 (0.16) NPI score points (P<0.001) and decreasing (mean (se)) by 130 (15) kJ (31.1 (3.65) kcal; P<0.001). This pattern was evident in all chains except Taco Bell, where pictured items increased in energy. Foods and beverages pictured on the kids' section showed the greatest nutritional improvements. Although promoted foods on general menu boards and signs improved in nutritional quality, beverages remained the same or became worse. CONCLUSIONS: Foods, and to a lesser extent, beverages, promoted on menu boards and signs in fast-food restaurants showed limited improvements in nutritional quality in 2013 v. 2010. PMID- 29580303 TI - Healthy changes in some cardiometabolic risk factors accompany the higher summertime serum 25-hydroxyvitamin D concentrations in Iranian children: National Food and Nutrition Surveillance. AB - OBJECTIVE: To investigate seasonal variations of vitamin D status at different latitudes and if these changes are accompanied by corresponding variations in certain health parameters in children living in a broad latitudinal range in Iran. DESIGN: Longitudinal study. SUBJECTS: In total, 530 apparently healthy children aged 5-18 years were randomly selected from six regions of Iran with a latitudinal gradient from 29 degrees N to 37.5 degrees N. All anthropometric and biochemical assessments were performed twice during a year (summer, winter). High BMI (Z-score >1), low HDL cholesterol (150 mg/dl) were considered cardiometabolic risk factors. RESULTS: Serum 25-hydroxyvitamin D (25(OH)D) showed between-season variation, with significantly higher concentrations (mean (sd)) in summer v. winter (43 (29) v. 27 (18) nmol/l; P33 degrees N v. <33 degrees N: 4.5; 0.09, 9.0; P=0.04) were predictors of change of serum 25(OH)D between two seasons. CONCLUSIONS: Summertime improvement of vitamin D status was accompanied by certain improved cardiometabolic risk factors, notably serum TAG, total cholesterol and BMI, in children. PMID- 29580304 TI - Impact of Discontinuing Contact Precautions for Methicillin-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococcus: An Interrupted Time Series Analysis. AB - : OBJECTIVETo investigate the impact of discontinuing contact precautions among patients infected or colonized with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) on rates of healthcare associated infection (HAI). DESIGN: Single-center, quasi-experimental study conducted between 2011 and 2016.METHODSWe employed an interrupted time series design to evaluate the impact of 7 horizontal infection prevention interventions across intensive care units (ICUs) and hospital wards at an 865-bed urban, academic medical center. These interventions included (1) implementation of a urinary catheter bundle in January 2011, (2) chlorhexidine gluconate (CHG) perineal care outside ICUs in June 2011, (3) hospital-wide CHG bathing outside of ICUs in March 2012, (4) discontinuation of contact precautions in April 2013 for MRSA and VRE, (5) assessments and feedback with bare below the elbows (BBE) and contact precautions in August 2014, (6) implementation of an ultraviolet-C disinfection robot in March 2015, and (7) 72-hour automatic urinary catheter discontinuation orders in March 2016. Segmented regression modeling was performed to assess the changes in the infection rates attributable to the interventions.RESULTSThe rate of HAI declined throughout the study period. Infection rates for MRSA and VRE decreased by 1.31 (P=.76) and 6.25 (P=.21) per 100,000 patient days, respectively, and the infection rate decreased by 2.44 per 10,000 patient days (P=.23) for device-associated HAI following discontinuation of contact precautions.CONCLUSIONThe discontinuation of contact precautions for patients infected or colonized with MRSA or VRE, when combined with horizontal infection prevention measures was not associated with an increased incidence of MRSA and VRE device-associated infections. This approach may represent a safe and cost-effective strategy for managing these patients.Infect Control Hosp Epidemiol 2018;39:676-682. PMID- 29580305 TI - Genotyping of individual Ceratonova shasta (Cnidaria: Myxosporea) myxospores reveals intra-spore ITS-1 variation and invalidates the distinction of genotypes II and III. AB - Genotypes of the myxosporean parasite Ceratonova shasta are defined by the number of ATC repeats in the parasite's ribosomal DNA internal transcribed spacer region 1. These genotypes correlate with specific salmonid fish hosts. We observed coho salmon (Oncorhynchus kisutch) and rainbow trout (Oncorhynchus mykiss) with mixtures of genotypes II and III, and assumed that this was a consequence of fish having an aggregate infection from multiple individual parasites. We hypothesized that although multiple ITS copies are present within a parasite spore, the DNA sequences of these copies are identical, and thus individual C. shasta spores are a single genotype. We tested this by extracting and sequencing DNA from individual myxospores. We trialed three approaches for in-tube DNA extraction; digestion with proteinase K was superior to simply rehydrating spores, or incubation in the buffer. Sequences from 14 myxospores were each a mixture of genotypes II and III. Therefore, intra-genomic ribosomal DNA variants exist within individual parasite spores, and II and III should no longer be regarded as discrete C. shasta genotypes. This single-spore genotyping approach will be a useful tool for testing validity of other C. shasta genotypes, and for correctly matching genotype with phenotype for mixed infections of other myxozoan species. PMID- 29580306 TI - Assessment of thyroid function in children, adults and pregnant and lactating women after long-term salt iodisation measurements. AB - Universal salt iodisation (USI) has been successfully implemented in China for more than 15 years. Recent evidence suggests that the definition of 'adequate iodine' (100-199 ug/l) be revised to 'sufficient iodine' (100-299 ug/l) based on the median urinary iodine concentration (MUI) in school-age children. The objective of this study was to determine the prevalence of thyroid dysfunction in populations after long-term salt iodisation and examine whether the definition of adequate iodine can be broadened to sufficient iodine based on the thyroid function in four population groups. A cross-sectional survey was conducted in six provinces in the northern, central and southern regions of China. Four population groups consisting of 657 children, 755 adults, 347 pregnant women and 348 lactating women were recruited. Three spot urinary samples were collected over a 10-d period and blood samples were collected on the 1st day. In the study, among the adults, pregnant women and lactating women, the prevalence rates of elevated thyroglobulin antibody and thyroid microsomal antibody levels were 12.4, 8.5 and 7.8 %, and 12.1, 9.1 and 9.1 %, respectively. Abnormally high thyroid dysfunction prevalence was not observed after more than 15 years of USI in China because the thyroid dysfunction rates were all <5 %. The recommended range should be cautiously broadened from adequate iodine to sufficient iodine according to the MUI of school-age children considering the high levels of hormones and antibodies in the other populations. Adults, particularly pregnant women positive for thyroid antibodies, should be closely monitored. PMID- 29580307 TI - n-3 PUFA and obesity: from peripheral tissues to the central nervous system. AB - The current paradigms of prevention and treatment are unable to curb obesity rates, which indicates the need to explore alternative therapeutic approaches. Obesity leads to several damages to the body and is an important risk factor for a number of other chronic diseases. Furthermore, despite the first alterations in obesity being observed and reported in peripheral tissues, studies indicate that obesity can also cause brain damage. Obesity leads to a chronic low-grade inflammatory state, and the therapeutic manipulation of inflammation can be explored. In this context, the use of n-3 PUFA (especially in the form of fish oil, rich in EPA and DHA) may be an interesting strategy, as this substance is known by its anti-inflammatory effect and numerous benefits to the body, such as reduction of TAG, cardiac arrhythmias, blood pressure and platelet aggregation, and has shown potential to help treat obesity. Thereby, the aim of this narrative review was to summarise the literature related to n-3 PUFA use in obesity treatment. First, the review provides a brief description of the obesity pathophysiology, including alterations that occur in peripheral tissues and at the central nervous system. In the sequence, we describe what are n-3 PUFA, their sources and their general effects. Finally, we explore the main topic linking obesity and n-3 PUFA. Animal and human studies were included and alterations on the whole organism were described (peripheral tissues and brain). PMID- 29580308 TI - Introduction: From "The Popularization of Science through Film" to "The Public Understanding of Science". AB - Science in film, and usual equivalents such as science on film or science on screen, refer to the cinematographic representation, staging, and enactment of actors, information, and processes involved in any aspect or dimension of science and its history. Of course, boundaries are blurry, and films shot as research tools or documentation also display science on screen. Nonetheless, they generally count as scientific film, and science in and on film or screen tend to designate productions whose purpose is entertainment and education. Moreover, these two purposes are often combined, and inherently concern empirical, methodological, and conceptual challenges associated with popularization, science communication, and the public understanding of science. It is in these areas that the notion of the deficit model emerged to designate a point of view and a mode of understanding, as well as a set of practical and theoretical problems about the relationship between science and the public. PMID- 29580309 TI - Harnessing the Persuasive Power of Narrative: Science, Storytelling, and Movie Censorship, 1930-1968. AB - Argument As the deficit model's failure leaves scientists searching for more effective communicative approaches, science communication scholars have begun promoting narrative as a potent persuasive tool. Narratives can help the public make choices by setting out a scientific issue's contexts, establishing the stakes involved, and offering potential solutions. However, employing narrative for persuasion risks embracing the same top-down communication approach underlying deficit model thinking. This essay explores the parallels between movie censorship and the current use of narrative to influence public opinion by examining how the Hays Office and the Catholic Legion of Decency responded to science in movies. I argue that deploying narratives solely as public relations exercises demonstrates the same mistrust of audiences that provided the foundation of movie censorship. But the history of movie censorship reveals the dangers of using narrative to remove the public's agency and to coerce them towards a preferred position rather than fostering their ability to come to their own conclusions. PMID- 29580310 TI - Taking Spectacle Seriously: Wildlife Film and the Legacy of Natural History Display. AB - Argument I argue through an analysis of spectacle that the relationship between wildlife documentary films' entertainment and educational mandates is complex and co-constitutive. Accuracy-based criticism of wildlife films reveals assumptions of a deficit model of science communication and positions spectacle as an external commercial pressure influencing the genre. Using the Planet Earth (2006) series as a case study, I describe spectacle's prominence within the recent blue chip renaissance in wildlife film, resulting from technological innovations and twenty-first-century consumer and broadcast market contexts. I connect spectacle in contemporary wildlife films to its relevant precursors within natural history, situating spectacle as a central feature of natural history display designed to inspire awe and wonder in audiences. I show that contemporary documentary spectacle is best understood as an opportunity for affective knowing rather than a constraint on accuracy; as a result, spectacle contributes to the virtuous inter-reinforcement of entertainment and education at work in blue-chip wildlife films. PMID- 29580311 TI - Configuring Epistemic Authority: The Significance of Film Style in Documentaries about Science. AB - Argument Among the many limitations of the deficit model of science communication is its inability to account for the qualities of communication products that arise from creative decisions about form and style. This paper examines two documentaries about the nature of time - Patricio Guzman's Nostalgia for the Light and the first episode of the BBC's Wonders of the Universe series - in order to consider how film style inflects science with different meanings. The analysis pays particular attention to the ways in which authority is assigned between film author, narrator, and depicted subjects and the degree to which different film styles promote epistemological certainty or hesitancy. PMID- 29580312 TI - The Shifting Aesthetics of Expertise in the Sharing Economy of Scientific Medicine. AB - Argument The deficit model of science communication assumes that the creation and dissemination of knowledge is limited to researchers with formal credentials. Recent challenges to this model have emerged among "e-patients" who develop extensive online activist communities, demand access to their own health data, conduct crowd-sourced experiments, and "hack" health problems that traditional medical experts have failed to solve. This article explores the aesthetics of medical media that enact the transition from a deficit model to a patient-driven model of visual representation and health communication. I present a framework for understanding the role of film and video in patient movements by analyzing the historical transition from researchers filming patients as nameless, voiceless human research subjects to patients recording their own health narratives through activist cinematography. By comparing several approaches to patient-centered video, I argue that imperfect production aesthetics play a critically important role in establishing the credibility of health communications. PMID- 29580313 TI - The Changing Nature of Modernization Discourses in Documentary Films. AB - Argument Franco's fascist regime in Spain (1939-1975) offers the possibility of exploring the complex relationship between media communication practices and the processes of production, circulation, and management of knowledge. The regime persistently used film, and later on television, as indoctrination and disciplining devices. These media thus served to shape the regime's representation, which largely relied on the generation of positive attitudes of adherence to the rulers through people's submission and obedience to experts. This article examines the changing nature of modernization discourses and practices, as a fundamental element of the regime's propaganda strategies, and as portrayed in documentaries produced under its rule. The rhetoric of modernization involved an explicit deficit model of knowledge management, which aimed at legitimating the regime's deeds and policies in its first decades, as we shall see regarding colonial-medical documentaries produced for the official newsreel in the 1940s. However, the focus of such rhetoric, despite its enduring political aims, had to somehow open up as the relationship between experts and non-experts changed, both in epistemological and practical terms, such as in wildlife documentary films produced for television in the 1970s, the regime's last decade. PMID- 29580314 TI - Accuracy, Authenticity, Fidelity: Aesthetic Realism, the "Deficit Model," and the Public Understanding of Science. AB - Argument "Deficit model" designates an outlook on the public understanding and communication of science that emphasizes scientific illiteracy and the need to educate the public. Though criticized, it is still widespread, especially among scientists. Its persistence is due not only to factors ranging from scientists' training to policy design, but also to the continuance of realism as an aesthetic criterion. This article examines the link between realism and the deficit model through discussions of neurology and psychiatry in fiction film, as well as through debates about historical movies and the cinematic adaptation of literature. It shows that different values and criteria tend to dominate the realist stance in different domains: accuracy for movies concerning neurology and psychiatry, authenticity for the historical film, and fidelity for adaptations of literature. Finally, contrary to the deficit model, it argues that the cinema is better characterized by a surplus of meaning than by informational shortcomings.

AB - Due to the lack of an effective prophylactic intervention and diagnosis, human liver fluke Clonorchis sinensis continues to afflict a large human population, causing a chronic inflammatory bile duct disease. With an aim to identify target antigens for sensitive serodiagnosis, adenylate kinase 3 of C. sinensis (CsAK3) was successfully expressed in soluble form in Escherichia coli by fusion to an RNA-interacting domain derived from human Lys-tRNA synthetase and purified by Ni2+-affinity chromatography. Anti-CsAK3 serum was raised by immunization of mice, and Western blotting confirmed that CsAK3 was expressed in adult-stage C. sinensis. Histochemical analysis showed that CsAK3 was localized to the subtegumental tissue of C. sinensis and was excreted into the bile duct of the host. When tested against sera from various parasite-infected patients by enzyme linked immunosorbent assay, the recombinant CsAK3 elicited a specific response to C. sinensis-infected sera. The results suggest that CsAK3, either alone or in combination with other antigens, could be used for improving the clinical diagnosis of clonorchiasis. PMID- 29580316 TI - Interventions to address household food insecurity in high-income countries. AB - Household food insecurity is a serious public health concern in high-income countries. Canada and the USA regularly monitor household food insecurity, while in other countries, such as the UK, it has been the rapid rise of food bank usage that has drawn increased attention to this longstanding, but largely overlooked, problem. This review evaluates evidence on interventions intended to reduce household food insecurity in high-income countries. Research on social protection interventions suggests both cash transfers and food subsidies (e.g. the US Supplement Nutrition and Assistance Programme) reduce household food insecurity. In contrast, research on community-level interventions, such as food banks and other food programmes, suggests limited impacts. Although food banks have become a common intervention for food insecurity in high-income countries, evidence suggests their reliance on donations of volunteer time and food make them inevitably limited in the assistance they are able to provide. The stigma people feel using food banks may also make them untenable. Alternatives to, or enhanced, food banks such as community shops or community kitchens, have become common, but evidence also suggests they may be limited in effectiveness if they do not reach people experiencing food insecurity. This review highlights the difficulty of trying to address household food insecurity with community-based food interventions when solutions likely lie upstream in social protection policies. PMID- 29580317 TI - Streptomyces salilacus sp. nov., an actinomycete isolated from a salt lake. AB - The taxonomic position of a novel actinomycete, strain TRM 41337T, isolated from sediment of a salt lake, Xiaoerkule Lake, Xinjiang, China, was determined by a polyphasic approach. Strain TRM 41337T grew optimally at 28 degrees C and in the presence of 1 % (w/v) NaCl. It grew at up to pH 12. The whole-cell sugars of strain TRM 41337T were ribose and xylose. The diagnostic diamino acid contained ll-diaminopimelic acid. The polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositolmannoside and two other unidentified phospholipids. The predominant menaquinones were MK-9(H8), MK-9, MK-9(H4) and MK-9(H6). The major fatty acids were iso-C16 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 1 H. Based on morphological and chemotaxonomic characteristics, the isolate was determined to belong to the genus Streptomyces. The phylogenetic tree based on its nearly complete 16S rRNA gene sequence (1498 nt) with representative strains showed that the strain consistently falls into a distinct phyletic lineage together with Streptomyces barkulensis DSM 42082T (97.48 % similarity) and a subclade consisting of Streptomyces fenghuangensis GIMN 4.003T (97.20 %), Streptomyces macrosporus NBRC 14748T (97.14 %) and Streptomyces radiopugnans R97T (97.01 %). On the basis of these data, strain TRM 41337T should be designated as a representative of a novel species of the genus Streptomyces, for which the name Streptomyces salilacus sp. nov. is proposed. The type strain is TRM 41337T (=CCTCC AA 2015030T=KCTC 39726T). PMID- 29580318 TI - alpha7-nAChR Knockout Mice Decreases Biliary Hyperplasia and Liver Fibrosis in Cholestatic Bile Duct-Ligated Mice. AB - alpha7-nAChR is a nicotinic acetylcholine receptor [specifically expressed on hepatic stellate cells (HSCs), Kupffer cells, and cholangiocytes] that regulates inflammation and apoptosis in the liver. Thus, targeting alpha7-nAChR may be therapeutic in biliary diseases. Bile duct ligation (BDL) was performed on wild type (WT) and alpha7-nAChR-/- mice. We first evaluated the expression of alpha7 nAChR by immunohistochemistry (IHC) in liver sections. IHC was also performed to assess intrahepatic bile duct mass (IBDM), and Sirius Red staining was performed to quantify the amount of collagen deposition. Immunofluorescence was performed to assess colocalization of alpha7-nAChR with bile ducts (costained with CK-19) and HSCs (costained with desmin). The mRNA expression of alpha7-nAChR, Ki-67/PCNA (proliferation), fibrosis genes (TGF-beta1, fibronectin-1, Col1alpha1, and alpha SMA), and inflammatory markers (IL-6, IL-1beta, and TNF-alpha) was measured by real-time PCR. Biliary TGF-beta1 and hepatic CD68 (Kupffer cell marker) expression was assessed using IHC. alpha7-nAChR immunoreactivity was observed in both bile ducts and HSCs and increased following BDL. alpha7-nAChR-/- BDL mice exhibited decreased (i) bile duct mass, liver fibrosis, and inflammation, and (ii) immunoreactivity of TGF-beta1 as well as expression of fibrosis genes compared to WT BDL mice. alpha7-nAChR activation triggers biliary proliferation and liver fibrosis and may be a therapeutic target in managing extrahepatic biliary obstruction. PMID- 29580319 TI - Liver and Pancreas: Do Similar Embryonic Development and Tissue Organization Lead to Similar Mechanisms of Tumorigenesis? AB - The liver and pancreas are closely associated organs that share a common embryological origin. They display amphicrine properties and have similar exocrine organization with parenchymal cells, namely, hepatocytes and acinar cells, secreting bile and pancreatic juice into the duodenum via a converging network of bile ducts and pancreatic ducts. Here we compare and highlight the similarities of molecular mechanisms leading to liver and pancreatic cancer development. We suggest that unraveling tumor development in an organ may provide insight into our understanding of carcinogenesis in the other organ. PMID- 29580320 TI - ICTV Virus Taxonomy Profile: Avsunviroidae. AB - Members of the family Avsunviroidae have a single-stranded circular RNA genome that adopts a rod-like or branched conformation and can form, in the strands of either polarity, hammerhead ribozymes involved in their replication in plastids through a symmetrical RNA-RNA rolling-circle mechanism. These viroids lack the central conserved region typical of members of the family Pospiviroidae. The family Avsunviroidae includes three genera, Avsunviroid, Pelamoviroid and Elaviroid, with a total of four species. This is a summary of the ICTV Report on the taxonomy of the family Avsunviroidae, which is available at http://www.ictv.global/report/avsunviroidae. PMID- 29580321 TI - Salinivirga fredricksonii gen. nov., sp. nov., a heterotrophic halophile isolated from a photosynthetic mat, a member of a novel lineage (Salinarimonadaceae fam. nov.) within the order Rhizobiales, and reclassification of the genus Salinarimonas Liu et al. 2010 into Salinarimonadaceae. AB - A halophilic bacterial strain, HL-109T, was isolated from the unicyanobacterial consortium UCC-O, which was obtained from the photosynthetic mat of Hot Lake (Washington, USA). A polyphasic approach using phenotypic, genotypic and chemotaxonomic data was used to classify the strain within the order Rhizobiales. The organism stained Gram-negative and was a moderate thermophile with a growth optimum of 45 degrees C. It was obligately aerobic, heterotrophic and halophilic, growing in both NaCl and MgSO4 brines. The novel isolate had a polymorphic cellular morphology of short rods with occasional branching, and cells were monotrichous. The major fatty acids detected were C18 : 1, C18 : 0, C16 : 0 and C18 : cyc. Phylogenetic analysis of the 16S rRNA gene placed the strain in the order Rhizobiales and it shared 94 % identity with the type strain of its nearest relative, Salinarimonas ramus. Morphological, chemotaxonomic and phylogenetic results did not affiliate the novel organism with any of the families in the Rhizobiales; therefore, HL-109T is representative of a new lineage, for which the name Salinivirga fredricksonii gen. nov., sp. nov. is proposed, with the type strain HL-109T (=JCM 31876T=DSM 102886T). In addition, examination of the phylogenetics of strain HL-109T and its nearest relatives, Salinarimonas ramus and Salinarimonasrosea, demonstrates that these halophiles form a clade distinct from the described families of the Rhizobiales. We further propose the establishment of a new family, Salinarimonadaceae fam. nov., to accommodate the genera Salinivirga and Salinarimonas (the type genus of the family). PMID- 29580322 TI - Two novel totiviruses in the white-backed planthopper, Sogatella furcifera. AB - There is little information about commensal viruses in the white-backed planthopper, Sogatella furcifera, although it is an important agricultural insect. Here, two novel double-stranded RNA viruses related to the viruses in the family Totiviridae were identified using next-generation sequencing and tentatively named Sogatella furcifera totivirus 1 and 2 (SfTV1 and SfTV2). Their complete genomes consist of 6310 and 6303 nt, respectively, showing typical genomic features with viruses in the family Totiviridae. Identity, phylogenetic and conserved sequence analyses showed that SfTV1, SfTV2 and three other insect viruses may form a proposed novel genus of the family Totiviridae. Vertical transmission of the two viruses was highly efficient, and they were detected in all insect tissues and developmental stages, with the highest titres in the adult and in the haemolymph and reproductive organs. To our knowledge, this is the first report of viruses in the family Totiviridae found in a hemipteran insect. PMID- 29580323 TI - Aquimarina celericrescens sp. nov., isolated from seawater. AB - An orange-coloured, slender rod-shaped, gliding bacterium, designated NS08T, was isolated from coastal water of Xiaoshi Island, Weihai, China (37 degrees 31' 36'' N 122 degrees 00' 58'' E). Cells were Gram-stain-negative, non-spore forming, non-flagellated, aerobic, catalase-positive and oxidase-negative. Growth occurred at 10-37 degrees C (optimum 30 degrees C), in the presence of 1.0-5.0 % (w/v) NaCl (optimum 2.0-3.0 %) and at pH 6.5-9.0 (optimum pH 7.0-7.5). Carotenoid pigments were produced but flexirubin-type pigments were not. The major fatty acids (>10 %) were iso-C15 : 0 and iso-C17 : 0 3-OH. The sole isoprenoid quinone of strain NS08T was menaquinone MK-6 and the DNA G+C content was 39.4 mol%. The polar lipid compositions of strain NS08T and the type strain of the type species of the genus Aquimarina, Aquimarina muelleri KCTC 12285T, were very similar with phosphatidylethanolamine, an unidentified aminolipid and two unknown polar lipids as the major components. A phylogenetic tree based on 16S rRNA gene sequences showed that strain NS08T formed an evolutionary lineage within the genus Aquimarina and shared the highest level of similarity to A. versatilis JCM 19528T (96.0 %) while level to A. muelleri KCTC 12285T was 95.0 %. Phenotypic characteristics distinguished strain NS08T from described members of the genus Aquimarina. On the basis of the evidence presented in this study, strain NS08T represents a novel species of the genus Aquimarina, for which the name Aquimarina celericrescens sp. nov. is proposed. The type strain is NS08T (=KCTC 52897T=MCCC 1H00191T). PMID- 29580324 TI - Emended description of Salinivibrio proteolyticus, including Salinivibrio costicola subsp. vallismortis and five new isolates. AB - We carried out a comparative taxonomic study of Salinivibrio proteolyticus and Salinivibrio costicola subsp. vallismortis, as well as of five halophilic strains (IB574, IB872, PR5, PR919 and PR932), isolated from salterns in Spain and Puerto Rico that were closely related to these bacteria. Multilocus sequence analysis of concatenated gyrB, recA, rpoA and rpoD housekeeping genes showed that they constituted a single cluster separate from the other species and subspecies of Salinivibrio. Experimental and in silico DNA-DNA hybridization studies indicated that they are members of the same species, with relatedness of 100-74 % and 97.8 70.0 %, respectively. The average nucleotide identity (ANI) determined for these strains was 99.7-95.6 % for ANIb and 99.7-95.7 % for OrthoANI. However, the ANI values for S. costicolasubsp.vallismortis DSM 8285T with respect to S. costicolasubsp.costicola DSM 11403T and S. costicolasubsp.alcaliphilus DSM 16359T were 78.7 and 78.9 % (ANIb) and 79.4 and 79.4 % (OrthoANI), respectively. The phylogenomic tree based on 1072 concatenated orthologous single-copy core genes confirmed that S. proteolyticus, S. costicolasubsp.vallismortis and the five new isolates constitute a coherent single phylogroup, separated from the other species and subspecies of Salinivibrio. All these data indicate that S. costicolasubsp.vallismortis is a heterotypic synonym of S. proteolyticus and we propose an emended description of this species.

AB - Becoming compliant with the Accreditation Council for Graduate Medical Education (ACGME) requirements for scholarly activity and remaining compliant over time requires time and attention to the development of an environment of inquiry, which is reflected in detailed documentation submitted in program applications and annual updates. Since the beginning of the next accreditation system, all ACGME programs have been required to submit evidence of scholarly activity of both residents and faculty on an annual basis. Since 2014, American Osteopathic Association-accredited programs have been able to apply for ACGME accreditation under the Single Graduate Medical Education Accreditation initiative. The Residency Program Director, Chair, Designated Institutional Official, Faculty, and coordinator need to work cohesively to ensure compliance with all program requirements, including scholarly activity in order for American Osteopathic Association-accredited programs to receive Initial ACGME Accreditation and for current ACGME-accredited programs to maintain accreditation. Fortunately, there are many ways to show the type of scholarly activity that is required for the training of surgeons. In this article, we will review the ACGME General Surgery Program Requirements and definitions of scholarly activity. We will also offer suggestions for how programs may show evidence of scholarly activity. PMID- 29580341 TI - Laparoscopic Heller Myotomy with Anterior Fundoplication Improves Frequency and Severity of Symptoms of Achalasia, Regardless of Preoperative Severity Determined by Esophagography. AB - This study was undertaken to determine whether postoperative outcomes after laparoscopic Heller myotomy with anterior fundoplication could be predicted by preoperative findings on esophagography. Preoperative barium esophagograms of 135 patients undergoing laparoscopic Heller myotomy with anterior fundoplication were reviewed. The number of esophageal curves, esophageal width, and angulation of the gastroesophageal junction (GEJ) were determined; correlations between these determined parameters and symptoms were assessed using linear regression analysis. The number of esophageal curves correlated with the preoperative frequency of dysphagia, vomiting, chest pain, regurgitation, and heartburn. The width of the esophagus negatively correlated with the preoperative frequency of regurgitation. The angulation of the GEJ did not correlate with preoperative symptoms. Laparoscopic Heller myotomy with anterior fundoplication significantly reduced the frequency and severity of all symptoms, regardless of the number of esophageal curves, esophageal width, or angulation of the GEJ. Laparoscopic Heller myotomy with anterior fundoplication provides dramatic palliation for achalasia. More esophageal curves on preoperative esophagography correlate well with the frequency of a broad range of preoperative symptoms, including the frequency of dysphagia and regurgitation. Patients experience dramatically improved frequency and severity of symptoms after laparoscopic Heller myotomy with anterior fundoplication for achalasia regardless of the number of esophageal curves, esophageal width, or the angulation of the GEJ. Findings on barium esophagogram, in evaluating achalasia, should not deter the application of laparosocopic Heller myotomy with anterior fundoplication. PMID- 29580342 TI - Early Uncomplicated Appendicitis-Who Can We Treat Nonoperatively? AB - This study evaluated nonoperative treatment for mild appendicitis and reviewed selection criteria to be used in introducing this option into clinical practice. A retrospective review of 73 consecutive cases of appendicitis treated by a single surgeon from 2011 to 2013 was completed. Patients who were diagnosed with mild appendicitis meeting the criteria of an APPENDICITIS scoring algorithm proposed in this manuscript were considered for nonoperative management. An additional 17 patients with mild appendicitis were offered and successfully treated nonoperatively between 2014 and 2016 and reviewed. Of these original 73 patients, 37 had moderate to severe appendicitis and directly underwent appendectomy. The remaining patients were diagnosed with mild appendicitis and considered eligible for nonoperative management. Of these, 14 patients were offered nonoperative therapy. Thirteen responded successfully; one patient responded partially, but later opted for surgery. In 2014, this scoring system and preliminary results were shared with the other surgeons in our department. Nonoperative management was then selectively adopted by a few of the surgeons from 2014 to 2016 with another 17 patients (APPENDICITIS score of 0 or 1) being offered and successfully managed nonoperatively. Patients with mild or early appendicitis can be successfully managed nonoperatively. A proposed APPENDICITIS scoring system may provide a helpful mnemonic for successfully selecting patients for this option. PMID- 29580343 TI - Incidence and Impact of Variant Celiacomesenteric Vascularization and Vascular Stenosis on Pancreatic Surgery Outcomes: Personal Experience. AB - Ischemic complications after pancreatic surgery can raise postoperative mortality from 4 to 83 per cent. Variants in vascular anatomy play a major role in determining such complications, but they have been only occasionally reported in the literature. We retrospectively analyzed 100 records of patients consecutively treated between January 2011 and December 2013 for resectable malignant diseases who underwent pancreaticoduodenectomy (PD) or total pancreatectomy to state the statistical impact of anatomical vascular variations in surgical outcomes (mean surgical timing, mean blood loss during surgery, and postoperative major complications onset) and to state whether preoperatively undetected vascular anomalies (VA) can raise the risk of postoperative ischemic complications. PD was performed in 89 patients, requiring multiorgan resections in three cases and total pancreatectomy was performed in 11 cases, which was associated to splenectomy in four patients. Incidence of VA was 25/100 (25%), whereas in 18/25 cases (72%) they were detected by preoperative radiologic setting. Their presence in patients undergoing PD significantly raised mean surgical timing (P = 0.003) and increased mean blood loss (P < 0.0001). Preoperatively undetected VA resulted in a major risk of postoperative acute liver ischemia (P = 0.008). Celiacomesenteric aberrant anatomy was proven to be related to an increased risk of intraoperative complications. If undetected preoperatively, they can be associated with anastomotic complications and liver failure. Maximal efforts must be done to detect and to preserve vascular anatomy of celiacomesenteric district. PMID- 29580344 TI - Building a Single-Site Robotic Cholecystectomy Program in a Public Teaching Hospital: Is It Safe for Patients and Feasible for Residents to Participate? AB - Single-site robotic cholecystectomy (SSRC) accounts for most of the robotic surgery cases performed by general surgeons at our institution since acquiring the da Vinci Si Surgical SystemTM (Intuitive Surgical, Inc., Sunnyvale, CA) in 2014. We sought to determine whether a SSRC program is safe to start in a public teaching hospital and to determine whether resident participation in this procedure is feasible. Data on age, gender, race, BMI, total operative time, length of stay, comorbidities, and conversion from laparoscopic to open surgery were examined for elective SSRC and laparoscopic cholecystectomies (LCs) performed by two faculty surgeons between February 2015 and August 2015. Thirty eight patients underwent elective SSRC, whereas 27 patients underwent LC. Residents participated as operating surgeons for some portion of the case in 15 SSRC cases and in all LC cases. There were no significant differences in operative time, length of stay, or 30-day readmission rates, regardless of resident involvement. Patients in the SSRC group had a significantly lower BMI (25.8 vs 33.7, P = 0.008). This study suggests that resident participation does not increase complications or total operative time and that SSRC is a safe procedure to start in a public teaching hospital after proper faculty and resident training. PMID- 29580345 TI - Minimally Invasive versus Open Simultaneous Resections of Colorectal Cancer and Synchronous Liver Metastases: A Meta-Analysis. AB - The aim of this meta-analysis was to compare the efficacy and safety of simultaneous resections between the minimally invasive approach (MIA) and the open approach (OA) for patients with colorectal cancer (CRC) and synchronous colorectal liver metastases (SCRLM). A systematic search was conducted in the Cochrane Library, PubMed, EMBASE and Ovid databases (until May 5, 2016). Studies comparing the perioperative results and long-term outcomes for patients undergoing simultaneous CRC and SCRLM resections between the two approaches were evaluated. Six studies were identified, which included 164 minimally invasive and 213 open simultaneous resections of CRC and SCRLM. MIA was associated with lesser surgical blood loss (mean difference = -155.85 mL; 95% confidence interval: 305.64 to -6.06, P = 0.04) and shorter length of postoperative stay (mean difference = -3.16 days; 95% confidence interval: -4.00 to -2.31, P < 0.00001.). The other perioperative results, including operating time, operative blood transfusion, intestinal function recovery time, and postoperative complications, did not differ significantly. No significant difference in the disease-free survival and overall survival rates between the two approaches was observed. In conclusion, compared with the OA, the MIA for simultaneous CRC and SCRLM resections is safe and effective for the treatment of SCRLM with lesser surgical blood loss and shorter length of postoperative stay. The MIA may be an alternative to the OA for simultaneous CRC and SCRLM resections for appropriately selected patients with resectable SCRLM. PMID- 29580346 TI - Head CT before Transfer Does Not Decrease Time to Craniotomy for TBI Patients. AB - Rural trauma education emphasizes that radiologic imaging should be discouraged if it delays transfer to definitive care. With increased capacity for image sharing, however, radiography obtained at referring hospitals (RH) could help providers at trauma centers (TC) prepare for patients with traumatic brain injury. We evaluated whether a head CT prior to transfer accelerated time to neurosurgical intervention at the TC. The study was conducted at a combined adult Level I and pediatric Level II TC with a catchment area that includes rural hospitals within a 150 mile radius. The trauma registry was used to identify patients with traumatic brain injury who went to surgery for a neurosurgical procedure immediately after arrival at the TC. All patients were transferred in from a RH. Differences between groups were assessed using analysis of variance and chi-square. Fifty-six patients met study criteria during the study period (2010-2015). The majority (86%) of patients received head CT imaging at the RH, including a significant percentage of patients (18%) who presented with GCS <=8. There was no statistically significant decrease in time to surgery when patients received imaging at the RH. CT imaging was associated with a delay in transfer that exceeded 90 minutes. Findings demonstrate that imaging at the RH delayed transfer to definitive care and did not improve time to neurosurgical intervention at the TC. Transfer to the TC should not be obstructed by imaging, especially for patients with severe TBI. PMID- 29580347 TI - Follow-Up Imaging in Patients with Blunt Splenic or Hepatic Injury Managed Nonoperatively. AB - Nonoperative management of blunt splenic and hepatic injuries has become the standard of care for hemodynamically stable patients. However, nonoperative management may lead to delayed complications and appropriate follow-up is therefore crucial. The aim of this systematic literature review was to assess the role of different imaging modalities in the follow-up assessment of patients with blunt splenic or hepatic injuries using the PubMed database. Eighteen studies were found to be relevant to the topic. A total of 2725 patients were enrolled in the included studies. Both retrospective and prospective studies, but no randomized controlled trials were found. In these studies, CT, ultrasound, and contrast-enhanced ultrasound were discussed. CT was the most commonly used imaging modality. Taking into account all studies included, only one patient underwent intervention due to a complication diagnosed by follow-up CT scan in the absence of clinical signs and symptoms. This equates to a total of 920 CT scans performed to diagnose one clinically nonevident complication that required intervention. Based on the reviewed literature, routine imaging follow-up CT scans may not be indicated in asymptomatic patients with lower grade blunt splenic or hepatic injuries. Contrast-enhanced ultrasound is a promising alternative imaging modality for the follow-up of these patients. PMID- 29580348 TI - Prosthetic Mesh Repair in the Emergency Management of Acutely Strangulated Groin Hernias with Grade I Bowel Necrosis: A Rational Choice. AB - The aim of this study was to determine the feasibility of prosthetic mesh repair according to the degree of bowel necrosis in the emergency management of acutely strangulated groin hernias. Emergency prosthetic mesh repair versus primary suture repair was randomly performed in 208 consecutive strangulated groin hernia patients with bowel necrosis between January 2005 and August 2016. The degree of bowel necrosis of each patient was determined according to a modified three-grade classification system. Patient characteristics sorted by repair method were analyzed by using Pearson's chi-squared tests. Correlations between mortality and wound-related morbidity with bowel necrosis grade and repair method were analyzed. There was no difference in gender, age, body mass index, comorbid diseases, hernia type (left or right, primary or recurrent), necrosis grade, and mortality between the mesh repair and suture repair groups (all P > 0.05). However, with regard to wound-related morbidity, there was significant difference between the two groups (P < 0.05). Mortality and wound-related morbidity showed significant relationship with necrosis grade, especially with regard to postoperative wound infection (P < 0.001). The wound infection rate with mesh repair was significantly higher than that with primary suture in Grade II and III necrosis patients (P < 0.05), but there was no difference in Grade I patients (P > 0.05). The use of prosthetic mesh in the emergency repair of acutely strangulated groin hernias seems to be as safe as suture-only repair in patients with noninfected strangulated bowel (Grade I necrosis). The use of prosthetic mesh repair is a rational choice made based on the degree of bowel necrosis in the emergency management of acutely strangulated hernias. PMID- 29580349 TI - eFAST for Pneumothorax: Real-Life Application in an Urban Level 1 Center by Trauma Team Members. AB - The focused assessment with sonography for trauma (FAST) examination has become the standard of care for rapid evaluation of trauma patients. Extended FAST (eFAST) is the use of ultrasonography for the detection of pneumothorax (PTX). The exact sensitivity and specificity of eFAST detecting traumatic PTX during practical "real-life" application is yet to be investigated. This is a retrospective review of all trauma patients with a diagnosis of PTX, who were treated at a large level 1 urban trauma center from March 2013 through July 2014. Charts were reviewed for results of imaging, which included eFAST, chest X-ray, and CT scan. The requirement of tube thoracostomy and mechanism of injury were also analyzed. A total of 369 patients with a diagnosis of PTX were identified. A total of 69 patients were excluded, as eFAST was either not performed or not documented, leaving 300 patients identified with PTX. A total of 113 patients had clinically significant PTX (37.6%), requiring immediate tube thoracostomy placement. eFAST yielded a positive diagnosis of PTX in 19 patients (16.8%), and all were clinically significant, requiring tube thoracostomy. Chest X-ray detected clinically significant PTX in 105 patients (92.9%). The literature on the utility of eFAST for PTX in trauma is variable. Our data show that although specific for clinically significant traumatic PTX, it has poor sensitivity when performed by clinicians with variable levels of ultrasound training. We conclude that CT is still the gold standard in detecting PTX, and clinicians performing eFAST should have adequate training. PMID- 29580350 TI - Frailty Predicts Morbidity after Colectomy for Ulcerative Colitis. AB - The rate of ulcerative colitis (UC), an inflammatory bowel disease, has been on the rise in the United States for the last several decades. Colectomy can be performed when other treatment options cannot provide a reasonable quality of life to patients with UC. Frailty has been shown to be a strong tool for evaluating preoperative risk factors for poor postoperative outcomes. The National Surgical Quality and Improvement Program cross-institutional database was used for this study. Data from 943 patients who underwent colectomy for UC between 2005 and 2012 were evaluated. Modified frailty index (mFI) is a previously described and validated 11-variable frailty measure used in the National Surgical Quality and Improvement Program to assess frailty. Outcome measures included serious morbidity; overall morbidity; cardiopulmonary, septic, and wound complications; and Clavien class IV (requiring ICU) and V (mortality) complications. Median age was 46 years and median body mass index was 25.5 Kg/m2. In all, 54.3 per cent of patients were male and 39.38 per cent of patients were American Society of Anesthesiologists Class lll or higher. The median mFI was 0 (0-0.54). As the mFI increased from 0 (nonfrail) to 0.18 and above, the overall morbidity increased from 25.40 to 52.1 per cent (P < 0.05), serious morbidity increased from 14.9 to 42.1 per cent (P < 0.05), septic complications increased from 9.87 to 21.49 per cent (P < 0.05), cardiopulmonary complications increased from 2.98 to 23.14 per cent (P < 0.05), Clavien class IV complications increased from 3.5 to 26.5 per cent (P < 0.05), and Clavien V complications increased from 0.16 to 6.61 per cent (P < 0.05). On multivariate analysis, mFI was an independent predictor of septic complications [Adjusted Odds Ratio (AOR): 31.26; P = 0.006], cardiopulmonary complications (AOR: 216.3; P <= 0.001), serious morbidity(AOR: 66.8; P <= 0.001), overall morbidity (AOR: 25.5; P <= 0.001), Clavien class IV (AOR: 204.9; P <= 0.001) complications, and return to the operating room (AOR: 14.29; P = 0.048). Frailty is associated with an increase in morbidity and mortality after colectomy in patients with UC. mFI is an easy-to use tool and can play an important role in the risk stratification of these patients. PMID- 29580351 TI - Short- and Long-Term Results of Laparoscopic Parenchyma-Sparing Hepatectomy for Small-Sized Hepatocellular Carcinoma: A Comparative Study Using Propensity Score Matching Analysis. AB - The aim of this study was to evaluate the degree of invasiveness and the clinical outcomes of laparoscopic parenchyma-sparing hepatectomy (LPSH) for a maximum hepatocellular carcinoma (HCC) size <=5 cm. Sixty-one LPSHs and 175 open parenchyma-sparing hepatectomies (OPSHs) for small-sized HCC were analyzed using a propensity score matching analysis. The median operative time was significantly shorter in the LPSH group (194 min) than in the OPSH group (275 minutes) (P < 0.0001). The estimated blood loss was significantly lower in the LPSH group (100 mL) than in the OPSH group (380 mL) (P < 0.0001). The incidences of superficial incisional surgical site infections and respiratory complications were significantly lower in the LPSH group than in the OPSH group (P = 0.0161 and 0.0285, respectively). During the postoperative course, the white blood cell counts and C-reactive protein levels were significantly lower in the LPSH group. There were no differences in overall survival and disease-free survival (P = 0.1293 and 0.4039, respectively), and no significant differences in terms of type of recurrence and site of intrahepatic recurrence (P = 0.1410). The data from the present series suggest the lesser invasiveness and safety of LPSH even for small sized HCC patients.

AB - Obesity and its associated metabolic disorders are strongly linked to both morbidity and mortality. Sleeve gastrectomy (SG) has been established as an effective means of weight loss for obese patients as well as a treatment for type 2 diabetes mellitus (T2DM). This study was designed to examine the short- and midterm outcomes of patients who underwent SG in a Middle Eastern Center of Excellence, a military training teaching hospital. The clinical outcomes of 59 patients with impaired glucose tolerance and T2DM who underwent SG between 2011 and 2014 with at least one and up to four years of follow-up were studied. Data were collected and compared, including the pre- and post-surgery measures of weight, body mass index, glycosylated hemoglobin (HbA1c), and fasting blood glucose. Complete remission was defined as a fasting blood glucose level <=100 mg/dL, an HbA1c <=6 mg/dL, without use of antidiabetic medications. All patients showed significant reduction in body mass index following SG. Tight glycemic control was achieved among both diabetic and prediabetic patients. In this study, 88.14 per cent of all patients (diabetic and prediabetic) achieved complete resolution from their impaired glucose tolerance and T2DM and maintained normal blood glucose and HbA1C levels from one to four years postoperatively. SG is beneficial both in terms of short- and midterm weight loss and glucose control in both diabetic and prediabetic obese patients. PMID- 29580353 TI - When Hiring New Trauma and Surgical Critical Care Fellowship Graduates, What Qualities Are Most Desirable? A Survey of Trauma Directors and Trauma Program Administrators. AB - : A general surgeon shortage exists and fewer surgical residents specialize in trauma and surgical critical care (TSCC). We conducted a survey of trauma directors and administrators to determine what qualities are most desirable when hiring new TSCC fellowship graduates. METHODS: The survey, entitled "A Survey of Directors of Trauma on Hiring New Attending Trauma Surgeons," was submitted to the Eastern Association for the Surgery of Trauma (EAST) and distributed to the association members in January 2016. Categorical data were summarized using frequency counts and percentages. Comparisons of responses were analyzed using the chi-squared or Fisher's exact test. Statistical significance was denoted by P < 0.05. RESULTS: A total of 317 respondents from 1364 submitted surveys presented a response rate of 23.2 per cent. Of these respondents, 85.8 per cent (n = 272) decide whether or not a new trauma surgeon is hired and 33.7 per cent were trauma directors. In all, 82.9 per cent work at academic centers and have an Accreditation Council for Graduate Medical Education-approved general surgery residency and 58.4 per cent have an Accreditation Council for Graduate Medical Education-approved surgical critical care or acute care surgery fellowship. In total, 72.6 per cent work in American College of Surgeons-verified trauma centers and 45.0 per cent hire new trauma surgeons as needed. Of the 272 respondents who decide whether or not a new trauma surgeon is hired, the recommendation of the residency and fellowship program director is important. Word of mouth was the most important manner of finding a new hire and the most important qualities of a new TSCC physician were personality and likeability. CONCLUSION: The survey revealed that well-trained, likeable, enthusiastic, and personable TSCC physicians are the best candidates for hire. PMID- 29580354 TI - Prehospital Extrication Techniques: Neurological Outcomes Associated with the Rapid Extrication Method and the Kendrick Extrication Device. AB - Most emergency medical service personnel rely on one of two techniques to extricate motor vehicle crash victims; the Rapid Extrication Maneuver (REM) or the Kendrick Extrication Device (KED). The purpose of this study was to compare pre- and postextrication neurological outcomes between these two techniques. A retrospective review was conducted of all adult patients with a vertebral column injury resulting from motor vehicle collision and admitted to a Level I trauma center between January 1, 2003 and December 31, 2010. Standardized pre- and postextrication neurological examinations were reviewed for all patients. More than half of patients (N = 81) were extricated using the KED (53.1%, n = 43) and 46.9 per cent (n = 38) were extricated with the REM. Except for the thoracic Abbreviated Injury Score, no differences between groups emerged related to the Glasgow Coma Scale score, Injury Severity Score or Abbreviated Injury Score. There were no pre- and postextrication changes for motor to all extremities and sensation to all extremities using either method. The results of this study suggest that the REM and the KED are equivalent in protecting the patient from neurologic injury after motor vehicle collision. PMID- 29580355 TI - A Cost-Benefit Analysis of Reducing Surgical Site Infections. AB - Surgical Site Infections (SSI) represent an onerous burden on our health-care system. This study was undertaken to determine the impact of a protocol aimed at reducing SSIs on the frequency and cost of SSIs after abdominal surgery. Beginning in 2013, 811 patients undergoing gastrointestinal operations were prospectively followed. In 2014, we initiated a protocol to reduce SSIs. SSIs were monitored before and after protocol implementation, and differences in SSI incidence and associated costs were determined. Before protocol initiation, standardized operative preparation cost was $40.85 to $126.94 per patient depending on the results of methicillin-resistant Staphylococcus aureus screen; after protocol initiation, the cost was $43.85 per patient, saving up to $83.09 per patient. With the protocol in place, SSI rate was reduced from 4.9 to 3.4 per cent (13 of 379) representing a potential prevention of eight infections that would have cost payers $166,280 ($20,785 per infection). Notably, the SSI rate after pancreatectomy was reduced by 63 per cent (P = 0.04). With preparation and diligence, SSI rate can be meaningfully reduced and potential cost savings can be achieved. In particular, SSI rate reduction for major abdominal operations and especially pancreatic resections can be achieved. A protocol to reduce SSI is a "win-win" for all stakeholders and should be encouraged with thoughtful and active participation from all hospital disciplines. PMID- 29580356 TI - Substernal Goiter: Correlation between Grade and Surgical Approach. AB - Substernal goiter is defined as a thyroid growth beyond the thoracic inlet. Using the cross-section imaging CT system, it can be classified into three grades. The aim of the study was to validate the surgical approach and the occurrence of postoperative complications with substernal goiter extension in our patient population. From a total of 1145 patients who underwent thyroid surgery at our institution in a 15-year period, 60 patients with substernal goiter were included. Clinical features and demographics, degree of extension, surgical details, and complications were analyzed. Mean +/- SD age of the patients was 58 +/- 14.7 years and 88 per cent were females. According to the cross-section imaging CT system 61.7 per cent were grade I, 23.3 per cent grade II, and 15 per cent grade III. Total thyroidectomy was performed in 78.3 per cent of the patients, subtotal thyroidectomy in 18.3 per cent, and lobectomy in 3.3 per cent. The cervical approach was sufficient to perform 96.7 per cent of the thyroidectomies, requiring partial sternotomy in only two patients with grade III substernal goiter. Patients with grade III substernal goiter had a higher risk for postoperative dysphonia (OR = 14.29, IC95% 1.14-178.9, P = 0.03), which occurred in three patients (two transient and one permanent). Transitory hypoparathyroidism was present in 20 patients (33.3%) and did not correlate with goiter extension. Most substernal goiters can be resected through a cervical approach, with relatively low morbidity. Postoperative dysphonia was directly related to the extension of the goiter. Few cases with grade III goiters require a partial sternotomy. PMID- 29580357 TI - Severe Bleeding in Pelvic Fractures: Considerations in Planning Damage Control. AB - Severe bleeding due to pelvic fractures may require damage control procedures, such as preperitoneal packing. In many cases, preperitoneal packing is performed without full abdominal exploration. There are concerns that such an approach may miss major iliac vascular injuries or other intraabdominal injuries. This analysis assessed the incidence of iliac vascular and intraabdominal injuries in patients with pelvic fractures. The National Trauma Data Bank was queried for blunt trauma patients. Patients with severe pelvic fractures were observed. Common or external iliac vascular lacerations (CEIVL) and associated intraabdominal injuries were recorded. The study comprised 42,122 patients with pelvic fractures, of which 3,221 (7.6%) were severe pelvic fractures. The incidence of CEIVL in patients with severe pelvic fractures was 10.7 per cent. Patient age greater than or equal to 65 years was an independent predictor of CEIVL. A total of 34.3 per cent of severe pelvic fracture patients had severe associated intraabdominal injuries, including injuries to the bladder (26.5%) and bowel (16.7%). Severe pelvic fractures are associated with a high incidence of iliac vascular and intraabdominal injuries. Preperitoneal pelvic packing without abdominal exploration may miss these injuries. PMID- 29580358 TI - Clinicopathological Features and Management of Appendiceal Mucoceles: A Systematic Review. AB - Appendiceal mucoceles (AMs) are rare mucin-containing neoplasms with malignant potential. Lack of evidence-based data exists defining clinicopathological features for management. MEDLINE search between 1995 and 2015 was performed using search criteria "Appendix mucocele." Systematic review of patient-, pathologic-, and treatment-related characteristics was performed and data analyzed. Among 276 cases of non-perforated AMs, 163 (59%) patients were female, with variable and nonspecific presentation. Patients were treated with appendectomy (52.1%), right hemicolectomy (17.6%), partial cecectomy (17.2%), and ileocecetomy (13.1%). Pathologic evaluation revealed the following: cystadenoma/low-grade appendiceal mucinous neoplasm (54%), unspecified/benign (25%), retention cyst (14.1%), cystadenocarcinoma (4.2%), and mucosal hyperplasia (2.9%). All 11 (4.2%) patients with cystadenocarcinoma were female (P = 0.004), odds ratio for malignancy 1.07 times higher for women. Synchronous colonic malignancy was reported in three patients (27%) with cystadenocarcinoma (P = 0.007), odds ratio of 12.1. AMs have low risk for malignancy. Treatment should begin with appendectomy-only and subsequently guided by pathologic diagnosis. PMID- 29580359 TI - Comparison of Transarterial Chemoembolization Combined with Radiofrequency Ablation Therapy versus Surgical Resection for Early Hepatocellular Carcinoma. AB - Both radiofrequency ablation (RFA) and surgical resection (SR) are radical treatment recommended for early hepatocellular carcinoma (HCC). Transarterial chemoembolization (TACE) is a palliative treatment for intermediate HCC, and TACE+RFA combined therapy is considered superior to TACE or RFA alone for management of early HCC. This systematic review compared the efficacy and safety of TACE+RFA combined therapy with SR for early HCC. Web of Science, PubMed, EMBASE, and the Cochrane Library were searched for literatures related with our topic. The primary endpoint was overall survival (OS), and the secondary endpoint was the recurrence-free survival (RFS) rate; safety was measured by the rate of major complications. The effect sizes of OS, RFS, and local progression rates were expressed by odds ratio (OR), while the effect size of complications was presented using relative risk. TACE+RFA combined therapy and SR had a similar 1 year OS rate [OR: 1.84; 95% confidence interval (CI): 0.82, 4.14; P > 0.05], 3 year OS rate (OR: 0.84; 95% CI: 0.43, 1.67; P > 0.05), 1-year RFS rate (OR: 0.77; 95% CI: 0.53, 1.11; P > 0.05), and 3-year RFS rate (OR: 0.88; 95% CI: 0.48, 1.42; P > 0.05) for early HCC. However, the 5-year OS rate (OR: 0.54; 95% CI: 0.40, 0.73; P < 0.05) and 5-year RFS rate (OR: 0.49; 95% CI: 0.27, 0.90; P < 0.05) were lower in patients with TACE+RFA than in those with SR. SR is associated with better long-term survival outcomes and a lower recurrence rate than TACE+RFA for patients with early HCC and is the optimal choice for patients with early HCC. PMID- 29580360 TI - Helmets Matter: Kentucky All-Terrain Vehicle Crashes Seen at a Tennessee Trauma Center. AB - All-terrain vehicle (ATV) safety laws, including helmet use, vary by state and are sporadically enforced. Kentucky state laws require safety helmets only for younger riders. We hypothesized that ATV riders injured in Kentucky and seen at a Tennessee trauma center would more likely be unhelmeted, have more severe head injuries, and have higher mortality rates than those injured in Virginia or Tennessee. A Trauma Registry review of 750 injured ATV riders from June 1, 2005, through June 1, 2015 examined state location of accident, helmet use, markers of injury severity, and outcomes. Multiple logistic regression analysis examined predictors of severe head injuries and death with P < 0.05 significant. Unhelmeted ATV rider status predicted more severe head injuries (relative risk 23.5, P < 0.001) and death (relative risk 4.6, P < 0.001). ATV riders injured in the state of Kentucky were twice as numerous. In addition, they were more likely than ATV riders injured in Tennessee or Virginia to be unhelmeted, to have severe head injuries, and to sustain fatal injuries (all P < 0.001). This single trauma center study lends support for maintaining and enforcing current universal helmet laws for ATV riders of all ages in states where they are in effect and highlights the need to upgrade helmet laws that apply only to some riders. PMID- 29580361 TI - Supervisor, Colleague, or Assistant: General Surgery Resident Perceptions of Advanced Practitioners. AB - Integration of advanced practitioners (APs) into academic medical centers can improve processes of care and decrease physician workload but may adversely impact general surgery residency training. The aim of the present study was to characterize general surgery resident perceptions of APs and their impact on resident training. We conducted an institutional review board-approved survey covering five topic areas: knowledge of AP training, interaction with APs, scope of-practice of APs, role of APs in the health-care team, and impact of APs on physician training. The survey was administered to general surgery residents at six large academic medical centers. One hundred eighteen general surgery residents completed the survey. The majority (43.6%) of respondents were junior residents. All respondents had interactions with APs with 90.7 per cent having worked directly with an AP in the last month. Residents reported minimal formal educational involvement by APs with 6.8 per cent reporting participation in didactics and 22.2 per cent teaching operative techniques. Almost half (44.1%) of the respondents reported that APs played an important role in their education, and 42.4 per cent of respondents disagreed or strongly disagreed that the role of the AP is well defined in their hospital. Today's general surgery residents work closely with APs who seem to positively impact resident education. Although residents perceive significant benefit with integration of APs, well-defined roles are lacking. PMID- 29580362 TI - Inadequacy of Algorithmic Ventilator-Associated Pneumonia Diagnosis in Acute Care Surgery. AB - Clinical utility of algorithms to diagnose ventilator-associated pneumonia (VAP) in surgical patients has not been established. We aimed to test the diagnostic accuracy of two established methods to reliably diagnose VAP in acutely ill and injured surgical patients. After institutional review board approval, we prospectively collected data on 508 mechanically ventilated acute care surgery patients. Microbiologic samples were taken daily from all patients. Demographics, clinical, laboratory, and radiographic data were collected. The Johanson Criteria (JC) and Clinical Pulmonary Infection Score (CPIS) were calculated and analyzed. Sensitivity, specificity, and positive predictive values (PPV) and negative predictive value (NPV) were calculated in comparison to positive respiratory cultures. Of the 508 patients, 312 (61.4%) were acutely injured; emergent general surgery was performed in 141 (27.8%) patients, and 54 (10.6%) underwent elective operation. Positive respiratory cultures were identified in 198 (39%) of the 508 patients. JC diagnosed VAP in 291 (57.3%) patients (sensitivity 82.8%, specificity 59%, PPV 56.4%, NPV 84.3%, accuracy 68.3%). The CPIS resulted in 189 (37.2%) VAP diagnoses (sensitivity 61.1%, specificity 78.1%, PPV 64%, NPV 75.9%, and accuracy 71.5%). To address the inaccuracy of the algorithms, concordance testing was performed on the data to evaluate correlation between the algorithmic VAP diagnosis criteria and respiratory culture data. Nonconcordance with culture data diagnosis was identified with both JC (rho 0.41) and CPIS (rho 0.41). Sensitivity, specificity, PPV and NPV, and accuracy of both established clinical formulas was unacceptably low in acute care surgery patients. PMID- 29580363 TI - Prospective Analysis of Epigastric, Umbilical, and Small Incisional Hernia Repair Using the Modified Kugel Oval Patch. AB - The study was performed to determine the complication and recurrence rate using the modified Kugel oval patch for small ventral hernia repair. Another aim of the study was to find risk factors for recurrence in patients with this repair. Seventy-three patients underwent ventral hernia repair with the modified Kugel oval patch between April 2013 and February 2015. Prospective follow-up data (18 months postoperative) were collected and evaluated. A total of 58 primary (18 epigastric/40 umbilical) and 15 incisional ventral hernias were repaired with the modified Kugel oval patch (7.6/10.2 cm/8 * 12 cm). We found three patients suffered superficial wound infection and two participants got hernia recurrence. Placement of mesh was found to be a significant risk factor for hernia recurrence. Small ventral hernia repair using the modified Kugel oval patch is a novel and useful approach and we recommend placing the patch preperitoneally.

PMID- 29580364 TI - Statewide Analysis Shows Collaborative Regional Trauma Network Reduces Regional Mortality. AB - A Regional Trauma Network (RTN), composed of one level I and several lower-level trauma centers (TCs) across multiple hospital systems, was established in 2010. This collaborative network used a unified triage protocol and a single transfer center. The impact of this RTN was assessed by evaluating regional mortality changes before and after RTN establishment. Patients in the state trauma registry aged 15 and older from 2006 to 2012 were analyzed; 2006 to 2009 and 2010 to 2012 were designated as pre-RTN and RTN periods, respectively. The region was defined as a county containing L1TC and its adjacent counties. Any counties bordering multiple L1TC-containing counties were excluded from analysis. Mortality was compared for all regions before and after RTN implementation. The following subgroups were also included a priori for the comparison: Injury Severity Score >=15, age >=65, and trauma mechanisms. 121,448 patients were analyzed; 66,977 and 54,471 patients were in the pre-RTN and RTN groups, respectively. Mean age was 58; 90 per cent had blunt injuries. The overall mortality was 4.9 per cent. Mortality comparisons over time for all regions are presented. The RTN region was the only region in the state that had mortality reduction in all patient subgroups. After adjusting for age, Injury Severity Score, level of TC that performed treatment, and trauma mechanism, RTN implementation was an independent predictor of survival (odds ratio: 0.876; 95% CI: 0.771-0.995, P = 0.04, c statistic: 0.84). These findings suggest that regional collaboration and network wide, uniform triage practices should be key components in the development of regionalized trauma networks.

PMID- 29580367 TI - Comparison of the Cepheid Xpert HPV test and the HC2 High-Risk HPV DNA Test for detection of high-risk HPV infection in cervical smear samples in SurePath preservative fluid. AB - PURPOSE: Cytological and histological cervical screening methods for human papillomavirus may be subjective. Current guidelines recommend the use of direct human papillomavirus screening by molecular methods in conjunction with cytology for the detection of high-risk human papillomavirus types with carcinogenic potential. In this study, we compared the performance of the molecular Cepheid Xpert HPV test to the FDA-approved HC2 High-Risk HPV DNA Test on samples from patients presenting for cervical screening, regardless of the cytology results, in which cervical cell samples were originally collected for Papanicolaou (Pap) smear specimens in Becton Dickinson (BD) SurePath preservative fluid. METHODOLOGY: Cervical cells were obtained for Pap smear specimens from 343 women attending Qatif Central Hospital in Saudi Arabia for cervical cancer screening using a Cytobrush Plus GT and immersed in BD SurePath preservative fluid in BD SurePath collection vials. The study was carried out between December 2015 and July 2016. RESULTS: The Xpert HPV test was positive in 27 (7.9 %) of the samples. The HC2 High-Risk HPV DNA Test was positive in 32 (9.3 %) of the samples. The most common HPV types according to the Xpert HPV test were HPV other types, either alone (n=15) or in combination with HPV16 (n=3). The overall concordance rate between the tests was 98.5 %. The positive concordance was 84.4 %. CONCLUSION: The Xpert HPV test is convenient to use on cervical cell samples collected for Pap smear specimens in BD SurePath preservative fluid within an hour and is a viable alternative to the HC2 High-Risk HPV DNA Test for HPV testing. PMID- 29580368 TI - Anaerobacillus isosaccharinicus sp. nov., an alkaliphilic bacterium which degrades isosaccharinic acid. AB - Strain NB2006T was isolated from an isosaccharinate-degrading, nitrate-reducing enrichment culture in minimal freshwater medium at pH 10. Analysis of the 16S rRNA gene sequence indicated that this strain was most closely related to species of the newly established genus Anaerobacillus. This was supported by phenotypic and metabolic characterisation that showed that NB2006T was rod-shaped, Gram stain-positive, motile and formed endospores. It was an aerotolerant anaerobe and an obligate alkaliphile that grew at pH 8.5-11, could tolerate up to 6 % (w/v) NaCl, and grew at a temperature between 10 and 40 degrees C. In addition, it could utilise a number of organic substrates, and was able to reduce nitrate and arsenate. The predominant cellular fatty acids were C16 : 0, C16 : 1omega11c, anteiso-C15 : 0, iso-C15 : 0, C16 : 1omega7c/iso-C15 : 0 2-OH and C14 : 0. The cell wall peptidoglycan contained meso-diaminopimelic acid and the DNA G+C content was 37.7 mol%. In silico DNA-DNA hybridization with the four known species of the genus Anaerobacillus showed 21.8, 21.9, 22.4, and 21.5 % relatedness to Anaerobacillusarseniciselenatis DSM 15340T, Anaerobacilus alkalidiazotrophicus DSM 22531T, Anaerobacillusalkalilacustris DSM 18345T, and Anaerobacillus macyae DSM 16346T, respectively. NB2006T differed from strains of other species of the genus Anaerobacillus in its ability to metabolise isosaccharinate, an alkaline hydrolysis product of cellulose. On the basis of the consensus of phylogenetic and phenotypic analyses, this strain represents a novel species of the genus Anaerobacillus, for which the name Anaerobacillus isosaccharinicus sp. nov. is proposed. The type strain is NB2006T (=DSM 100644T=LMG 30032T). PMID- 29580369 TI - Mechanism of activation of the BNLF2a immune evasion gene of Epstein-Barr virus by Zta. AB - The human gamma herpes virus Epstein-Barr virus (EBV) exploits multiple routes to evade the cellular immune response. During the EBV lytic replication cycle, viral proteins are expressed that provide excellent targets for recognition by cytotoxic T cells. This is countered by the viral BNLF2a gene. In B cells during latency, where BNLF2a is not expressed, we show that its regulatory region is embedded in repressive chromatin. The expression of BNLF2a mirrors the expression of a viral lytic cycle transcriptional regulator, Zta (BZLF1, EB1, ZEBRA), in B cells and we propose that Zta plays a role in up-regulating BNLF2a. In cells undergoing EBV lytic replication, we identified two distinct regions of interaction of Zta with the chromatin-associated BNLF2a promoter. We identify five potential Zta-response elements (ZREs) in the promoter that are highly conserved between virus isolates. Zta binds to these elements in vitro and activates the expression of the BNLF2a promoter in both epithelial and B cells. We also found redundancy amongst the ZREs. The EBV genome undergoes a biphasic DNA methylation cycle during its infection cycle. One of the ZREs contains an integral CpG motif. We show that this can be DNA methylated during EBV latency and that both Zta binding and promoter activation are enhanced by its methylation. In summary, we find that the BNLF2a promoter is directly targeted by Zta and that DNA methylation within the proximal ZRE aids activation. The implications for regulation of this key viral gene during the reactivation of EBV from latency are discussed. PMID- 29580370 TI - Identification of a newly described OsHV-1 uvar from the North Adriatic Sea (Italy). AB - The surveillance activities for abnormal bivalve mortality events in Italy include the diagnosis of ostreid herpesvirus type 1 (OsHV-1) in symptomatic oysters. OsHV-1-positive oysters (Crassostrea gigas) were used as a source for in vivo virus propagation and a virus-rich sample was selected to perform shotgun sequencing based on Illumina technology. Starting from this unpurified supernatant sample from gills and mantle, we generated 3.5 million reads (2*300 bp) and de novo assembled the whole genome of an Italian OsHV-1 microvariant (OsHV-1-PT). The OsHV-1-PT genome encodes 125 putative ORFs, 7 of which had not previously been predicted in other sequenced Malacoherpesviridae. Overall, OsHV-1 PT displays typical microvariant OsHV-1 genome features, while few polymorphisms (0.08 %) determine its uniqueness. As little is known about the genetic determinants of OsHV-1 virulence, comparing complete OsHV-1 genomes supports a better understanding of the virus pathogenicity and provides new insights into virus-host interactions. PMID- 29580371 TI - Small RNA Esr41 inversely regulates expression of LEE and flagellar genes in enterohaemorrhagic Escherichia coli. AB - Enterohaemorrhagic Escherichia coli (EHEC) is a life-threatening human pathogen worldwide. The locus of enterocyte effacement (LEE) in EHEC encodes a type three secretion system and effector proteins, all of which are essential for bacterial adherence to host cells. When LEE expression is activated, flagellar gene expression is down-regulated because bacterial flagella induce the immune responses of host cells at the infection stage. Therefore, this inverse regulation is also important for EHEC infection. We report here that a small regulatory RNA (sRNA), Esr41, mediates LEE repression and flagellar gene activation. Multiple copies of esr41 abolished LEE expression by down-regulating the expression of ler and pch, which encode positive regulators of LEE. This regulation led to reduced EHEC adhesion to host cells. Translational gene reporter fusion experiments revealed that Esr41 regulates ler expression at a post-transcriptional level, and pch transcription, probably via an unknown target of Esr41. Esr41-mediated ler and pch repression was not observed in cells lacking hfq, which encodes an RNA-binding protein essential for most sRNA functions, indicating that Esr41 acts in an Hfq-dependent manner. We previously reported an increase in cell motility induced by Esr41. This motility enhancement was also observed in EHEC lacking ler, showing that Esr41-mediated enhancement of cell motility is in a ler-independent manner. In addition, Esr41 activated the expression of flagellar Class 3 genes by indirectly inducing the transcription of fliA, which encodes the sigma factor for flagellar synthesis. These results suggest that Esr41 plays important roles in the inverse regulation of LEE and flagellar gene expression. PMID- 29580372 TI - Neptunicoccus sediminis gen. nov., sp. nov., a member of the family Rhodobacteraceae isolated from the Yellow Sea. AB - A novel Gram-stain-negative bacterium, designated strain CY02T, was isolated from sediment of the Yellow Sea. Cells of CY02T were aerobic, coccus or short rods. Growth occurred at 5-42 degrees C (optimum, 35 degrees C), pH 6-10 (optimum, 8.0) and 0.5-9.0 % NaCl (optimum, 1.5-3.0 %). Phylogenetic analysis of 16S rRNA gene sequences revealed that CY02T was a member of the family Rhodobacteraceae and exhibited less than 95 % sequence similarities with the closely related type strains of the family Rhodobacteraceae. The genomic DNA G+C content of CY02T was 57.5 mol%. The major respiratory quinone was ubiquinone-10 (Q-10). The polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, three unidentified lipids, one unidentified phospholipid and one unidentified aminolipid. The predominant cellular fatty acids were C18 : 1omega7c (57.6 %), 11-methyl C18 : 1omega7c (22.8 %) and C16 : 0 (10.6 %). Based on the results of morphological, physiological, biochemical, chemotaxonomic, genotypic and phylogenetic analyses, strain CY02T represents a novel species of a novel genus of the family Rhodobacteraceae, for which the name Neptunicoccus sediminis gen. nov., sp. nov. is proposed. The type strain of Neptunicoccus sediminis is CY02T (=CCTCC AB 2015430T=KCTC 42985T=NBRC 111872T=MCCC 1K03518). PMID- 29580373 TI - Comparative analysis of prions in nervous and lymphoid tissues of chronic wasting disease-infected cervids. AB - The prevalence, host range and geographical bounds of chronic wasting disease (CWD), the prion disease of cervids, are expanding. Horizontal transmission likely contributes the majority of new CWD cases, but the mechanism by which prions are transmitted among CWD-affected cervids remains unclear. To address the extent to which prion amplification in peripheral tissues contributes to contagious transmission, we assessed the prion levels in central nervous and lymphoreticular system tissues in white-tailed deer (Odocoileus virginianus), red deer (Cervus elaphus elaphus) and elk (Cervus canadensis). Using real-time quaking-induced conversion, cervid prion cell assay and transgenic mouse bioassay, we found that the retropharyngeal lymph nodes of red deer, white-tailed deer and elk contained similar prion titres to brain from the same individuals. We propose that marked lymphotropism is essential for the horizontal transmission of prion diseases and postulate that shed CWD prions are produced in the periphery. PMID- 29580374 TI - Mitochondrial dysfunction suppresses p53 expression via calcium-mediated nuclear factor-kB signaling in HCT116 human colorectal carcinoma cells. AB - Mitochondrial DNA (mtDNA) mutations are often observed in various cancer types. Although the correlation between mitochondrial dysfunction and cancer malignancy has been demonstrated by several studies, further research is required to elucidate the molecular mechanisms underlying accelerated tumor development and progression due to mitochondrial mutations. We generated an mtDNA-depleted cell line, rho0, via long-term ethidium bromide treatment to define the molecular mechanisms of tumor malignancy induced by mitochondrial dysfunction. Mitochondrial dysfunction in rho0 cells reduced drug-induced cell death and decreased the expression of pro-apoptotic proteins including p53. The p53 expression was reduced by activation of nuclear factor-kappaB that depended on elevated levels of free calcium in HCT116/rho0 cells. Overall, these data provide a novel mechanism for tumor development and drug resistance due to mitochondrial dysfunction. [BMB Reports 2018; 51(6): 296-301].

AB - CONSTANS (CO) induces the expression of FLOWERING LOCUS T (FT) in the photoperiodic pathway, and thereby regulates the seasonal timing of flowering. CO expression is induced and CO protein is stabilized by FLAVIN-BINDING KELCH REPEAT F-BOX PROTEIN 1 (FKF1) in the late afternoon, while CO is degraded by CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) during the night. These regulatory cascades were thought to act independently. In our study, we investigated the relationship between FKF1 and COP1 in the regulation of CO stability in response to ambient light conditions. A genetic analysis revealed that FKF1 acts as a direct upstream negative regulator of COP1, in which cop1 mutation is epistatic to fkf1 mutation in the photoperiodic regulation of flowering. COP1 activity requires the formation of a hetero-tetramer with SUPPRESSOR OF PHYA-105 (SPA1), [(COP1)2(SPA1)2]. Light-activated FKF1 has an increased binding capacity for COP1, forming a FKF1-COP1 hetero-dimer, and inhibiting COP1 homo-dimerization at its coiled-coil (CC) domain. Mutations in the CC domain result in poor COP1 dimerization and misregulation of photoperiodic floral induction. We propose that FKF1 represses COP1 activity by inhibiting COP1 dimerization in the late afternoon under long-day conditions, resulting in early flowering. [BMB Reports 2018; 51(4): 163-164]. PMID- 29580376 TI - High-throughput non-invasive prenatal testing for fetal rhesus D status in RhD negative women not known to be sensitised to the RhD antigen: a systematic review and economic evaluation. AB - BACKGROUND: High-throughput non-invasive prenatal testing (NIPT) for fetal rhesus (D antigen) (RhD) status could avoid unnecessary treatment with routine anti-D immunoglobulin for RhD-negative women carrying a RhD-negative fetus, although this may lead to an increased risk of RhD sensitisations. OBJECTIVES: To systematically review the evidence on the diagnostic accuracy, clinical effectiveness and implementation of high-throughput NIPT and to develop a cost effectiveness model. METHODS: We searched MEDLINE and other databases, from inception to February 2016, for studies of high-throughput NIPT free-cell fetal deoxyribonucleic acid (DNA) tests of maternal plasma to determine fetal RhD status in RhD-negative pregnant women who were not known to be sensitised to the RhD antigen. Study quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) and A Cochrane Risk of Bias Assessment Tool: for Non-Randomised Studies of Interventions (ACROBAT-NRSI). Summary estimates of false-positive rates (FPRs) and false-negative rates (FNRs) were calculated using bivariate models. Clinical effectiveness evidence was used to conduct a simulation study. We developed a de novo probabilistic decision tree-based cohort model that considered four alternative ways in which the results of NIPT could guide the use of anti-D immunoglobulin antenatally and post partum. Sensitivity analyses (SAs) were conducted to address key uncertainties and model assumptions. RESULTS: Eight studies were included in the diagnostic accuracy review, seven studies were included in the clinical effectiveness review and 12 studies were included in the review of implementation. Meta-analyses included women mostly at or post 11 weeks' gestation. The pooled FNR (women at risk of sensitisation) was 0.34% [95% confidence interval (CI) 0.15% to 0.76%] and the pooled FPR (women needlessly receiving anti-D) was 3.86% (95% CI 2.54% to 5.82%). SAs did not materially alter the overall results. Data on clinical outcomes, including sensitisation rates, were limited. Our simulation suggests that NIPT could substantially reduce unnecessary use of antenatal anti-D with only a small increase in the risk of sensitisation. All large implementation studies suggested that large-scale implementation of high-throughput NIPT was feasible. Seven cost effectiveness studies were included in the review, which found that the potential for the use of NIPT to produce cost savings was dependent on the cost of the test. Our de novo model suggested that high-throughput NIPT is likely to be cost saving compared with the current practice of providing routine antenatal anti-D prophylaxis to all women who are RhD negative. The extent of the cost saving appeared to be sufficient to outweigh the small increase in sensitisations. However, the magnitude of the cost saving is highly sensitive to the cost of NIPT itself. LIMITATIONS: There was very limited evidence relating to the clinical effectiveness of high-throughput NIPT, with no evidence on potential adverse effects. The generalisability of the findings to non-white women and multiple pregnancies is unclear. CONCLUSIONS: High-throughput NIPT is sufficiently accurate to detect fetal RhD status in RhD-negative women from 11 weeks' gestation and would considerably reduce unnecessary treatment with routine anti-D immunoglobulin, potentially resulting in cost savings of between L485,000 and L671,000 per 100,000 pregnancies if the cost of implementing NIPT is in line with that reflected in this evaluation. FUTURE WORK: Further research on the diagnostic accuracy of NIPT in non-white women is needed. STUDY REGISTRATION: This study is registered as PROSPERO CRD42015029497.

AB - : Background In Germany, drug use in sexual settings (i.e. chemsex) among men who have sex with men (MSM) has increasingly been the subject of discussion for considerable time. At the same time, however, little is known about this practice. It is against this background that what is currently known about chemsex among MSM in Germany is discussed. METHODS: The present study observations are essentially based on the results of two research projects of a qualitative-explorative nature. In-depth interviews with drug-using MSM (n=14), as well as qualitative, problem-centred interviews with drug-using MSM (n=75) and expert interviews (n=27) were conducted within these research projects. RESULTS: Chemsex is a minority behaviour among MSM in Germany. The reasons for using drugs in sexual settings are manifold. For the most part, the effects of the drugs are used to intensify sexual feelings and to achieve greater intimacy. Men who consider their consumption to be problematic, in particular, report a range of negative consequences, such as sexually transmissible infections. Even though chemsex is a minority behaviour, suitable offers of support are, hence, necessary, especially for these men. However, such offers are not yet available in most German cities. CONCLUSIONS: In order to close this gap in provision of support services, tangible practical steps, such as further training of people who work at drug and gay advisory services, are necessary, along with further research into the backgrounds and contexts of chemsex. PMID- 29580378 TI - Hypoexcitability precedes denervation in the large fast-contracting motor units in two unrelated mouse models of ALS. AB - Hyperexcitability has been suggested to contribute to motoneuron degeneration in amyotrophic lateral sclerosis (ALS). If this is so, and given that the physiological type of a motor unit determines the relative susceptibility of its motoneuron in ALS, then one would expect the most vulnerable motoneurons to display the strongest hyperexcitability prior to their degeneration, whereas the less vulnerable should display a moderate hyperexcitability, if any. We tested this hypothesis in vivo in two unrelated ALS mouse models by correlating the electrical properties of motoneurons with their physiological types, identified based on their motor unit contractile properties. We found that, far from being hyperexcitable, the most vulnerable motoneurons become unable to fire repetitively despite the fact that their neuromuscular junctions were still functional. Disease markers confirm that this loss of function is an early sign of degeneration. Our results indicate that intrinsic hyperexcitability is unlikely to be the cause of motoneuron degeneration.

AB - Single-cell RNA-sequencing is revolutionising our understanding of seemingly homogeneous cell populations but has not yet been widely applied to single-celled organisms. Transcriptional variation in unicellular malaria parasites from the Plasmodium genus is associated with critical phenotypes including red blood cell invasion and immune evasion, yet transcriptional variation at an individual parasite level has not been examined in depth. Here, we describe the adaptation of a single-cell RNA-sequencing (scRNA-seq) protocol to deconvolute transcriptional variation for more than 500 individual parasites of both rodent and human malaria comprising asexual and sexual life-cycle stages. We uncover previously hidden discrete transcriptional signatures during the pathogenic part of the life cycle, suggesting that expression over development is not as continuous as commonly thought. In transmission stages, we find novel, sex specific roles for differential expression of contingency gene families that are usually associated with immune evasion and pathogenesis. PMID- 29580380 TI - Resilience of small intestinal beneficial bacteria to the toxicity of soybean oil fatty acids. AB - Over the past century, soybean oil (SBO) consumption in the United States increased dramatically. The main SBO fatty acid, linoleic acid (18:2), inhibits in vitro the growth of lactobacilli, beneficial members of the small intestinal microbiota. Human-associated lactobacilli have declined in prevalence in Western microbiomes, but how dietary changes may have impacted their ecology is unclear. Here, we compared the in vitro and in vivo effects of 18:2 on Lactobacillus reuteri and L. johnsonii. Directed evolution in vitro in both species led to strong 18:2 resistance with mutations in genes for lipid biosynthesis, acid stress, and the cell membrane or wall. Small-intestinal Lactobacillus populations in mice were unaffected by chronic and acute 18:2 exposure, yet harbored both 18:2- sensitive and resistant strains. This work shows that extant small intestinal lactobacilli are protected from toxic dietary components via the gut environment as well as their own capacity to evolve resistance. PMID- 29580381 TI - Origin and evolution of the nuclear auxin response system. AB - The small signaling molecule auxin controls numerous developmental processes in land plants, acting mostly by regulating gene expression. Auxin response proteins are represented by large families of diverse functions, but neither their origin nor their evolution is understood. Here, we use a deep phylogenomics approach to reconstruct both the origin and the evolutionary trajectory of all nuclear auxin response protein families. We found that, while all subdomains are ancient, a complete auxin response mechanism is limited to land plants. Functional phylogenomics predicts defined steps in the evolution of response system properties, and comparative transcriptomics across six ancient lineages revealed how these innovations shaped a sophisticated response mechanism. Genetic analysis in a basal land plant revealed unexpected contributions of ancient non-canonical proteins in auxin response as well as auxin-unrelated function of core transcription factors. Our study provides a functional evolutionary framework for understanding diverse functions of the auxin signal. PMID- 29580382 TI - High levels of histones promote whole-genome-duplications and trigger a Swe1WEE1 dependent phosphorylation of Cdc28CDK1. AB - Whole-genome duplications (WGDs) have played a central role in the evolution of genomes and constitute an important source of genome instability in cancer. Here, we show in Saccharomyces cerevisiae that abnormal accumulations of histones are sufficient to induce WGDs. Our results link these WGDs to a reduced incorporation of the histone variant H2A.Z to chromatin. Moreover, we show that high levels of histones promote Swe1WEE1 stabilisation thereby triggering the phosphorylation and inhibition of Cdc28CDK1 through a mechanism different of the canonical DNA damage response. Our results link high levels of histones to a specific type of genome instability that is quite frequently observed in cancer and uncovers a new mechanism that might be able to respond to high levels of histones.

PMID- 29580385 TI - Synergistic effect of kappa-carrageenan and gelatin blends towards adipose tissue engineering. AB - The current paper focuses on the functionalization of kappa-carrageenan and gelatin as extracellular matrix polysaccharide and protein mimic respectively to produce hydrogel films for adipose tissue engineering. More specifically, kappa carrageenan as well as gelatin have been functionalized with methacrylate and methacrylamide moieties respectively to enable subsequent UV-induced crosslinking in the presence of a photo-initiator. The gel fraction, the mass swelling ratio and the mechanical properties of both the one-component hydrogels and the protein/polysaccharide blends have been evaluated. The mechanical and swelling properties of the blends could be tuned by varying the hydrogel composition as well as the crosslinking method applied. The in vitro biocompatibility assays indicated a significantly higher cell viability of adipose tissue-derived mesenchymal stem cells seeded onto the blends as compared to the one-component hydrogels. The results show that the blends of gelatin and kappa-carrageenan clearly outperform the one-component hydrogels in terms of adipose tissue engineering potential. PMID- 29580386 TI - Two structurally similar fucosylated chondroitin sulfates from the holothurian species Stichopus chloronotus and Stichopus horrens. AB - Two fucosylated chondroitin sulfates SC and SH were isolated from the holothurian species Stichopus chloronotus and Stichopus horrens, respectively. The molar ratio of monosaccharides and sulfate (GalNAc:GlcA:Fuc:SO3Na) was suggested as ~1:1:1:4 for both polysaccharides. Really this theoretical ratio was slightly distorted by the presence of some fucan sulfate in both preparations (about 2% in SH and 10% in SC), which could not be separated probably due to coincidence with the main components in charge density and molecular weight. The 1D and 2D NMR spectroscopic methods were applied for the detailed structural characterization of SC and SH, which were found to have similar structures. The main chain of SC and SH was shown to be composed of the repeating disaccharide units ->4)-beta-d GlcA-(1 -> 3)-beta-d-GalNAc-(1-> sulfated at O-4 or both at O-4 and O-6 of the N acetyl-galactosaminyl residues. The ratio of mono- and disulfated GalNAc residues was determined as 1:9 for SC and SH. Only one type of branches linked to O-3 of glucuronyl residues, namely fucosyl 2,4-disulfate residues, were found in both polysaccharides. Therefore polysaccharides SC and SH are two new examples of highly regular fucosylated chondroitin sulfates. PMID- 29580384 TI - The asymmetrically segregating lncRNA cherub is required for transforming stem cells into malignant cells. AB - Tumor cells display features that are not found in healthy cells. How they become immortal and how their specific features can be exploited to combat tumorigenesis are key questions in tumor biology. Here we describe the long non-coding RNA cherub that is critically required for the development of brain tumors in Drosophila but is dispensable for normal development. In mitotic Drosophila neural stem cells, cherub localizes to the cell periphery and segregates into the differentiating daughter cell. During tumorigenesis, de-differentiation of cherub high cells leads to the formation of tumorigenic stem cells that accumulate abnormally high cherub levels. We show that cherub establishes a molecular link between the RNA-binding proteins Staufen and Syncrip. As Syncrip is part of the molecular machinery specifying temporal identity in neural stem cells, we propose that tumor cells proliferate indefinitely, because cherub accumulation no longer allows them to complete their temporal neurogenesis program. PMID- 29580387 TI - Synthesis of novel grafted hyaluronic acid with antitumor activity. AB - In our study, we aimed to synthesize novel grafted hyaluronic acid with cationic biodegradable polymer, poly (N-vinyl imidazole) (PVI), through free radical polymerization using potassium persulfate as initiator. The effect of various grafting factors including initiator and monomer concentrations, reaction time and temperature was studied on the percentage of grafting parameters such as; graft yield (% GY), grafting efficiency (% GE) and amount of homopolymer formation (% H). Maximum grafted HA was% GY = 235% and%GE = 83% obtained on optimum conditions at [In] = 17.5 mmol L-1, [M] = 1.25 mol L-1, Temp. = 50 degrees C, time = 1.5 h and [HA] = 0.025 mol L-1. The structure of grafted HA (HA g-PVI) was elucidated via various analysis tools such as; elemental analyses, FTIR, 1H NMR, XRD, TGA and Field emission scanning electron microscopy (FE-SEM). Hepatic and breast cancers are two common cancer types threatening people worldwide, so, the antitumor activity of two grafted HA samples (% GY = 155% and 235%) was studied against hepatic cancer (HepG-2) and breast cancer cell lines (MCF-7) compared to unmodified HA and PVI. The results showed that antitumor activity of grafted samples was more than unmodified HA and increased with increasing the grafting percentage of PVI onto HA chains, also, the antitumor activity of tested samples against HepG-2 cell lines was higher than MCF-7 cell lines. PMID- 29580388 TI - Development of gelatin/carboxymethyl chitosan/nano-hydroxyapatite composite 3D macroporous scaffold for bone tissue engineering applications. AB - The present study delineates a relatively simpler approach for fabrication of a macroporous three-dimensional scaffold for bone tissue engineering. The novelty of the work is to obtain a scaffold with macroporosity (interconnected networks) through a combined approach of high stirring induced foaming of the gelatin/carboxymethyl chitosan (CMC)/nano-hydroxyapatite (nHAp) matrix followed by freeze drying. The fabricated macroporous (SGC) scaffold had a greater pore size, higher porosity, higher water retention capacity, slow and sustained enzymatic degradation rate along with higher compressive strength compared to that of non-macroporous (NGC, prepared by conventional freeze drying methodology) scaffold. The biological studies revealed the increased percentage of viability, proliferation, and differentiation as well as higher mineralization of differentiated human Wharton's jelly MSC microtissue (wjhMSC-MT) on SGC as compared to NGC scaffold. RT-PCR also showed enhanced expression level of collagen type I, osteocalcin and Runx2 when seeded on SGC. MUCT and histological analysis further revealed a penetration of cellular spheroid to a greater depth in SGC scaffold than NGC scaffold. Furthermore, the effect of cryopreservation on microtissue survival on the three-dimensional construct revealed significant higher viability upon revival in macroporous SGC scaffolds. These results together suggest that high stirring based macroporous scaffolds could have a potential application in bone tissue engineering.

AB - In the present work, the corrosion resistance performance and biocompatibility of polypyrrole/chitosan (PPy/CHI) composite coated Ti was studied. The deposition of composite coating was carried out by electropolymerization method. The deposited PPy/CHI composite coatings were different in morphology, structural, surface roughness and wettability compared PPy coated Ti. The presence of composite coating was confirmed by solid 13C NMR. The PPy/CHI composite coating showed enhanced microhardness and adhesion strength compared to the PPy coating. The corrosion protection ability of PPy/CHI composite coatings at various applied potentials was analyzed by dynamic electrochemical impedance spectroscopy (DEIS), exhibited higher impedance in all the potentials compared to uncoated and PPy coated Ti. The lower corrosion current density obtained for PPy/CHI-2 composite coating from polarization studies revealed increased corrosion protection ability in SBF solution. The stability of composite coating was confirmed by immersion studies. PPy/CHI-2 composite coating immersed in SBF solution enhances hydroxyapatite (HAp) formation.

AB - In the current article cellulose pulp extracted from mesquite tree was characterized and used as a raw material for preparation of carboxymethyl cellulose (CMC) which further used for preparing nanocomposite. CMC/Fe3O4 nanocomposite was synthesized by co-precipitation of iron (II) and (III) salts by aqueous ammonia in CMC solution. Cellulose pulp, CMC and CMC/Fe3O4 materials were characterized by using FTIR, XRD, TGA, SEM and TEM analysis. The results showed that homogenous spherical magnetic nanoparticles with diameter ~25 nm were formed. The nanocomposite was further applied to remove methylene blue (MB) from aqueous solutions. The adsorption experiments showed the maximum adsorption capacity at pH 7. The adsorption results were analyzed by different isotherm and kinetic models and the results were fitted well with the Langmuir model and pseudo second-order model respectively. The current article showed that mesquite tree is a new resource for cellulose pulp which could be employed for preparing sustainable and environmentally friendly composite materials. PMID- 29580391 TI - Cellulose ultrafine fibers embedded with titania particles as a high performance and eco-friendly separator for lithium-ion batteries. AB - Mixtures of cellulose acetate (M.W. ~3 * 104 g/mol) dissolved in 75% v/v acetic acid in water (17% w/w) and ground anatase titania particles with diameters of 197 +/- 75 nm (0%, 5% and 10% w/w) were electrospun at 17 kV with a fiber collection distance and a feed rate of 10 cm and 0.6 mL/h. Then, the fiber was treated with 0.5 M potassium hydroxide in ethanol. Rough regenerated cellulose (RC)-titania separators with diameters of ~310 nm and uniformly dispersed titania particles showed ~78% porosities. They decomposed at 300 degrees C, higher than the decomposition temperature of polyethylene separators (220 degrees C). Added titania particles increased the electrolyte wettability and lithium transference number (from 0.22 to 0.62). RC - 10% titania separator retained the capacity with 79 mA h/g after 30 cycles and had excellent discharge capacity. These fascinating properties make RC-titania separator promising for lithium ion battery. PMID- 29580392 TI - Improved miscibility of PA6 and chitosan by the electric-field assisted phase inversion. AB - A facile and efficient method for the improved miscibility of natural polymer/synthetic polymer blends is reported here based on the electric-field driven phase inversion. We have employed bioderived chitosan (CS) and Polyamide-6 (PA6) as an example since their blends are known to always result in a large scale phase separation (i.e. CS settles to the bottom of the blends as sediment) during phase inversion procedure. The condensed structure of the polymer blends has been well characterized, notably by the polarized attenuated total reflectance infrared spectroscopy and proton longitudinal relaxation time (T1) distribution. The application of an electric field can orient the polar groups which will hinder the crystallization of blends and also increase the interphase interaction between PA6 and CS. The miscibility of the PA6/CS blends has been characterized by scanning electron microscopy and confocal Raman spectroscopy. It is shown that this controllable hydrogen bonding environment, induced by the presence of electric field, indeed greatly hinder the sedimentation of CS without destroying its chemical structure. The improved miscibility of PA6/CS blends can thus significantly increase the toughness and generate a somewhat larger tensile strength.

AB - A low-cost, high-adsorption-capacity, eco-friendly bioadsorbent for removing Cd2+ from aqueous solution is reported. J-g-P(AM-co-AANa) was prepared by hydrolysis of the grafted copolymer, which was synthesized by free radical polymerization of acrylamide (AM) with jute fibers (JSE) pretreated by continuous screw-extrusion steam explosion. Fourier transform infrared and solid-state 13C nuclear magnetic resonance spectroscopies, confirmed that amino and carboxylate groups were introduced into J-g-P(AM-co-AANa). X-ray diffraction showed that the crystallinity of J-g-P(AM-co-AANa) was significantly lower than that of JSE. The surface morphology of bioadsorbent was investigated by scanning electron microscopy (SEM). The adsorption capacity of Cd2+ on J-g-P(AM-co-AANa) was evaluated for different solution pH values, contact times, and initial Cd2+ concentrations. The adsorption kinetics followed the pseudo-second-order kinetic model, and the rate controlling step was chemisorption. The adsorption isotherm was well fitted by the Freundlich model, and the adsorption process was multilayer adsorption. The maximum adsorption capacity was 344.8 mg/g, which indicated that the bioadsorbent was effective for removing Cd2+ from aqueous solution. PMID- 29580394 TI - Size-dependent pharmacological activities of differently degraded fucoidan fractions from Fucus vesiculosus. AB - Fucose-containing sulfated glycans (syn. fucoidans) from brown algae exhibit a wide range of bioactivities and are therefore considered promising candidates for health-supporting and medical applications. In this study, we investigated the pharmacological activities of fucoidan from Fucus vesiculosus and 18 gradually depolymerized fractions, which were obtained by hydrothermal and H2O2 treatment, respectively. All the activities decreased with decreasing molecular mass (Mw) but to a different extent resulting in some modified pharmacological profiles in dependence on the Mw as well as on the degradation method. H2O2 treatment was not only more efficient, simpler and cheaper than hydrothermal degradation, but also led to superior activity profiles and additionally eliminated co-extracted contaminants. Compared to heparin, the prime example of biologically active sulfated glycans, evenly sized H2O2 fractions exhibited considerable effects being relevant for anti-inflammatory activity, however only negligible anticoagulant activity and FXII activating potency. Due to their improved biopharmaceutical characteristics and favorable activities, degraded fucoidan fractions are worth to be further investigated as anti-inflammatory and anticomplementary agents.

AB - Fique fibers are extracted from Furcraea spp. leaves, with 5% average mass yield, using mechanical decortication. Juice, pulp and tow, the by-products of this process, amount 95% of the leaf weight and are considered waste. We extracted cellulose nanofibrils (CNF) from Fique tow, via ultrasound-assisted TEMPO followed by mechanical disintegration with sonication. Fique CNF exhibit diameters around 100 nm, degree of oxidation (DO) of 0.27 and surface charge density (sigma) of 1.6 mmol/g. Fique CNF aqueous suspensions show optical birefringence and high colloidal stability due to a high zeta potential (-53 mV). The morphology, chemical structure, crystallinity and phase transitions of Fique CNF were studied using FESEM, IR-ATR, XRD and TGA. We observed that the delignification pretreatment and the TEMPO reaction assisted by ultrasound significantly increase Fique CNF sigma and zeta potential, in contrast with the oxidation carried out without ultrasound or with raw (lignified) tow. PMID- 29580396 TI - Chitin nanocrystals prepared by oxidation of alpha-chitin using the O2/laccase/TEMPO system. AB - Laccase mediator oxidation was applied to chitin at pH 6.8 and 30 degrees C to prepare chitin nanocrystals with a catalytic amount of 2,2,6,6 tetramethylpiperidine-1-oxyl radical (TEMPO). When 40 mM TEMPO and a total of 500 U laccase were added to 1 g chitin, the yield of water-insoluble oxidized chitin was more than 95%, and the carboxylate content was 0.43 mmol/g. Adsorption of laccase molecules on chitin particles occurred in a buffer at pH 6.8, which may have been caused by electrostatic interactions between positively charged C2 ammonium groups of chitin and anionically charged groups of laccase. Rod-like chitin nanocrystals (ChNCs) were obtained with average lengths and widths of 480 +/- 200 nm and 24 +/- 17 nm, respectively, by sonication of the oxidized chitin/water suspensions. The O2/laccase/TEMPO oxidation caused no decrease in the degree of N-acetylation or the crystallinity of the original chitin based on FTIR and X-ray diffraction data.

AB - Double helix formation from the non-natural anionic and cationic amylose analog polysaccharides (amylouronic acid and amylosamine, respectively) was achieved through electrostatic interactions. A water-insoluble complex was obtained by simply mixing the two polysaccharides in water. The 1H NMR analysis indicated that the formation of the complexes with an approximately equimolar unit ratio from the two polysaccharides was resulted regardless of feed ratios for mixing. The powder X-ray diffraction (XRD) measurement suggested that the helix had larger sizes both in diameter and pitch compared with well-known amylose double helix. The formation of the double helical structure was also examined by theoretical calculations. The double helix models, differing in a chain polarity and a charge state of the residues, were constructed based on the 6-fold left handed amylose chain of the A-amylose crystal structure. Molecular dynamics calculations indicated that those with an antiparallel chain polarity retained an intertwined form. The antiparallel double helical model with the free form residues was suggested to be the most likely structure for the non-natural polysaccharides.

AB - Combining the advantages of both cellulose and ionic liquid, ionic liquid functionalized cellulose (ILFC) as adsorbent was prepared through radiation grafting glycidyl methacrylate onto cellulose microsphere following by reaction with ionic liquid 1-aminopropyl-3-methyl imidazolium nitrate. Its adsorption properties towards Cr(VI) were investigated in batch and column experiments. In batch experiments, the adsorption kinetics was well fitted with pseudo-second order mode with equilibrium time of 2 h and the adsorption capacity reached 181.8 mg/g at pH 2 calculated from Langmuir model. In fixed column, both Yoon-Nelson and Thomas models gave satisfactory fit to experimental data and breakthrough curves, and equilibrium adsorption capacity calculated by Thomas model was 161.0 mg/g. Moreover, ILFC exhibited high selectivity towards Cr(VI) even in synthetic chrome-plating wastewater. Besides, adsorption/desorption test revealed ILFC can be regenerated and reused several times without obvious decrease in adsorbed amount. The adsorption process was demonstrated to anion exchange-reduction mechanism via XPS analysis.

AB - An important preventive measure for providing a bacteria-free environment for the patients is the introduction of highly efficient and durable antibacterial textiles in hospitals. This work describes a single step sono-enzymatic process for coating of cotton medical textiles with antibacterial ZnO nanoparticles (NPs) and gallic acid (GA) to produce biocompatible fabrics with durable antibacterial properties. Cellulose substrates, however, need pre-activation to achieve sufficient stability of the NPs on their surface. Herein, this drawback is overcome by the simultaneous sonochemical deposition of ZnO NPs and the synthesis of a bio-based adhesive generated by the enzymatic cross-linking of GA in which the NPs were embedded. GA possesses the multiple functions of an antibacterial agent, a building block of the cross-linked phenolic network, and as a compound providing the safe contact of the coated materials with human skin. The ZnO NPs GA coated fabrics maintained above 60% antibacterial efficacy even after 60 washing cycles at 75 degrees C hospital laundry regime. PMID- 29580400 TI - A promptly approach from monosaccharides of biomass to oligosaccharides via sharp quenching thermo conversion (SQTC). AB - In this study, a novel and facile approach of conversion monosaccharides (glucose and xylose) to oligosaccharides (Cello-oligosaccharides and Xylo oligosaccharides) was demonstrated. The approach did not introduce any chemical reagent and the preparation process could be environmentally friendly. Identification and quantification by ion chromatography (IC) and high performance liquid chromatography (HPLC) showed that the yields of COS and XOS reached to 44.62% (38 s) and 47.09% (30 s) respectively at 500 degrees C reaction temperature coupled with sharp-quenching method. Structural characterization indicated that such oligosaccharides showed a degree of polymerization (DP) with 2-6, and the units mainly linked by beta-(1 -> 4)-glycosidic bond. PMID- 29580402 TI - Preparation and characterization of green-nano-composite material based on polyaniline, multiwalled carbon nano tubes and carboxymethyl cellulose: For electrochemical sensor applications. AB - In this paper, we are presenting the preparation and characterization of "polyaniline/multiwalled carbon nanotubes/carboxymethyl cellulose" based novel composite material. It's morphological, thermal, structural, and electrochemical properties were investigated by using different instrumental techniques. During the in-situ chemical polymerization of aniline in the aqueous suspension of CMC and MWCNTs, the particle size change in two different ways "top to bottom" (low molecular weight oligomers grows in size) and "bottom to top" (long fibers of CMC fragmented in the reaction mixture). The combination of these two processes facilitated the fabrication of an integrated green-nano-composite material. In addition, a little amount of conductive nanofillers (MWCNTs) boosts the electrical and electrocatalytic properties of the material. Electron-rich centers of benzenoid rings exhibited pi-pi stacking with sp2 carbon of MWCNTs. CMC dominantly impact on the properties of PANI, negatively charged carboxylate group of CMC ionically bonded with protonated amine/imine. FTIR and Raman analysis confirmed that the material has dominated quinoid units and effective charge transfer. Hydroxyl and carboxyl groups and bonded water molecules of CMC results in a network of hydrogen bonds (which induced directional property). PANI/MWCNTs/CMC have nanobead-like structures (TEM analysis), large surface area, large pore volume, small pore diameter (BET and BJH studies) and good dispersion ability in the aqueous phase. Nanostructures of aligned PANI exhibited excellent electrochemical properties have attracted increasing attention. Modified carbon paste electrode was used for electrocatalytic detection of ascorbic acid (as a model analyte). The sensor exhibited a linear range 0.05 mM-5 mM, sensitivity 100.63 MUA mM-1 cm-2, and limit of detection 0.01 mM. PANI/MWCNTs/CMC is suitable nanocomposite material for apply electroactive/conducting ink and membrane (which could be used in electrochemical sensor applications).

AB - Polymer sanxan is a novel microbial polysaccharide produced by Sphingomonas sanxanigenens NX02, which can produce poly-3-hydroxybutyrate (PHB) simultaneously. A strategy of combining rational and random gene manipulation was investigated to improve the yield of sanxan. Several crucial PHB biosynthesis genes were deleted through homologous recombination, then the PHB-deficient mutant was treated with plasma mutagenesis to obtain NXdP, an engineering strain. Ultimately, the yield of purified sanxan produced by strain NXdP increased from 14.88 +/- 0.83 g/L to 21.20 +/- 0.38 g/L in a 5 L bioreactor, while the cell dry weight (CDW) was decreased from 9.61 +/- 0.14 g/L to 3.12 +/- 0.15 g/L. The total precipitable material (crude sanxan) produced from NXdP showed higher zero-shear viscosity, light transmittance, and greater gel strength than that from NX02 due to the enhancement of its purity. The engineering strategies explored here are useful for engineering cell factories to produce other valuable metabolites.

AB - Neural tissue engineering (TE), an innovative biomedical method of brain study, is very dependent on scaffolds that support cell development into a functional tissue. Recently, 3D patterned scaffolds for neural TE have shown significant positive effects on cells by a more realistic mimicking of actual neural tissue. In this work, we present a conductive nanocellulose-based ink for 3D printing of neural TE scaffolds. It is demonstrated that by using cellulose nanofibrils and carbon nanotubes as ink constituents, it is possible to print guidelines with a diameter below 1 mm and electrical conductivity of 3.8 * 10-1 S cm-1. The cell culture studies reveal that neural cells prefer to attach, proliferate, and differentiate on the 3D printed conductive guidelines. To our knowledge, this is the first research effort devoted to using cost-effective cellulosic 3D printed structures in neural TE, and we suppose that much more will arise in the near future.

AB - Microorganisms can spread on the surface of banknotes and cause many infectious diseases. Chitosan nanofibers (CNFs) and cellulose nanocrystals (CNCs) are nanomaterials, which can affect the antimicrobial properties. In this study, the fungal species that grew on the surfaces of collected banknotes from different places were identified. To examine the antifungal effect of the both nanomaterials on the banknotes, the stable coatings using CNFs and CNCs emulsions were prepared by roller coating. The results revealed that the most colonies in the banknotes obtained from the bakeries and butcheries were Aspergillus sp., whereas the colonies in bus terminals and the hospitals were Aspergillus niger and Penicillium, respectively. The results showed that the CNCs had no antifungal effect alone on the aforementioned species, but it could improve the antifungal effect, adhesion, and stability of CNFs on the banknote surfaces. This study suggested a new approach to decrease the infection spreads through banknotes. PMID- 29580405 TI - Physical characterization and modeling of chitosan/peg blends for injectable scaffolds. AB - Injectable scaffolds find many applications on the biomedical field due to several advantages on preformed scaffolds such as being able to fill any defect can be used in minimal invasion surgeries and are ready to use products. The most critical parameter for an injectable scaffold usage is its injectability, which can be related with rheological properties. Therefore, the objective of the present work was to increase knowledge about the critical parameters influencing injectability of biopolymers used for injectable scaffolds. Rheological and mechanical properties of a biopolymer blend in combination with injectability tests for a given design space controlled by the concentrations of both polymers and temperatures was made. Then those results were modeled to better understand the impact of parameters on injectability. The biopolymer blend chosen was Chitosan physically blended with Poly(ethylene glycol) where variations of both polymer concentrations and molecular weights were tested. Rheological and mechanical properties of all samples were determined, together with the injection force using a compression test at different injection conditions. All solutions were clear and transparent suggesting perfect miscibility. Rheological results were modeled using Ostwald-Waelle law and revealed a shear thinning pseudo plastic solution at any composition and temperature, being chitosan concentration the most influencing variable. Compression tests results revealed mean injection forces ranging from 9.9 +/- 0.06N to 29.9 +/- 0.65N and it was possible to accurately estimate those results. Simulations revealed draw speed as the most influencing parameter. Cell viability tests revealed a non-cytotoxic biopolymer blend. PMID- 29580406 TI - Novel method for holocellulose analysis of non-woody biomass wastes. AB - Compositional analysis of non-woody biomass is quite important to determine its possible applications. However, current standard methods developed for woody biomass compositional analysis have been revealed to be unsuitable when applied to non-woody biomass. Therefore, a novel and less-time consuming modified method which enables for a proper isolation of holocellulose in non-woody biomass samples while increasing lignin degradation has been developed. The novel method mainly consists in a treatment with sodium chlorite and glacial acetic acid at boiling point, which precludes changes in the holocellulose crystallinity degree or losses of carbohydrates, as shown by DSC, XRPD, and HPLC analysis. It was successfully applied to the determination of the structural components of 10 different non-woody biomass samples. Also, its use revealed that non-woody biomass belongs to LHC and LCH groups in the biomass structural composition ternary diagram, which are completely different than the ones the woody biomass belongs to. PMID- 29580407 TI - Chitosan/waste coffee-grounds composite: An efficient and eco-friendly adsorbent for removal of pharmaceutical contaminants from water. AB - Waste coffee-grounds (WCG), a poorly explored source of biocompounds, were combined with chitosan (Cs) and poly(vinyl alcohol) (PVA) in order to obtain composites. Overall, WCG showed a good interaction with the polymeric matrix and good dispersibility up to 10 wt-%. At 5 wt-% WCG, the composite exhibited a noticeable enhancement (from 10 to 44%) of the adsorption of pharmaceuticals (metamizol (MET), acetylsalicylic acid (ASA), acetaminophen (ACE), and caffeine (CAF)) as compared to the pristine sample. The highest removal efficiency was registered at pH 6 and the removal followed the order ASA > CAF > ACE > MET. For all pharmaceuticals, the adsorption kinetics was found to follow the pseudo second order model, while the adsorption mechanism was explained by the Freundlich isotherm. Reuse experiments indicated that the WCG-containing composite has an attractive cost-effectiveness since it presented a remarkable reusability in at least five consecutive adsorption/desorption cycles. PMID- 29580408 TI - Factors affecting the properties of nitrocellulose emulsions: A comparative study. AB - In this study the influence of viscosity and chemical nature of dispersed phase, preparation conditions and storage temperature on the properties of nitrocellulose emulsions produced by gel emulsification (G) and direct mechanical emulsification (D) methods were examined. Chemical nature of dispersed phase had no effect on the drop size for both methods; however it had a significant effect on emulsion stability. Viscosity of dispersed phase did not considerably affect drop breakage process in route G, while strongly affected drop breakage in route D. Addition rate had no significant effect on the drop size produced by route D; while for route G high addition rate resulted in catastrophic phase inversion. The drop size produced by route D decreased dramatically by increasing stirring speed, whereas stirring speed had a minimal effect on the drop breakage process in route G. Finally, it was found that emulsion stability was greatly influenced by storage temperature.

AB - Hyaluronic acid (HA) modified with an aldehyde group (HA-CHO) has enormous potential for the covalent attachment of the amino compounds and for the crosslinking of HA with bis or multi-functional amino linkers under physiological conditions. Modification of HA-CHO to its alpha,beta-unsaturated analogue (DeltaHA-CHO) generally increases the stability of the reversible imino attachment due to conjugation of the imine moiety with the adjacent CC double bound. Conjugation of a wide range of structurally different amines including the amines with enhanced biological activity were studied in detail. Results showed that the stabilities of the final conjugates DeltaHACHNR significantly depend on the chemical structure of the amine and on the pH value. PMID- 29580410 TI - Reinforcement of thermoplastic chitosan hydrogel using chitin whiskers optimized with response surface methodology. AB - To strengthen the mechanical strength of thermo-sensitive hydroxybutyl chitosan (HBC) hydrogel, chitin whiskers were used as sticker to fabricate reinforced HBC (HBCW) hydrogel by using response surface methodology. Unlike the intrinsic network of HBC hydrogel, HBCW hydrogel showed a laminar shape with firm structure. The preparation condition was optimized by three-factor-three-level Box-Behnken design. The maximum mechanical strength (1011.11 Pa) was achieved at 50 degrees C, when the concentrations of HBC and chitin whiskers were 5.1 wt% and 2.0 wt%, respectively. The effects of temperature, pH value and NaCl concentration on mechanical strength of HBCW hydrogels were investigated via the oscillatory stress sweeps. The results showed that HBCW hydrogel could reach the maximum stiffness (~1126 Pa) at 37 degrees C pH 12.0. Low pH and high salty ions could decrease the stability of hydrogel, while chitin whiskers could increase the stress tolerance and related ruptured strain of HBCW hydrogels. PMID- 29580411 TI - Polysaccharides from Dendrobium huoshanense stems alleviates lung inflammation in cigarette smoke-induced mice. AB - The present work investigated the inhibitory activity of the polysaccharide from cultivated Dendrobium huoshanense (cDHP) on lung inflammation in cigarette smoke (CS)-induced mouse model. cDHP was mainly composed of mannose and glucose in a molar ratio of 1.89: 1.00, and had a backbone with linkages of 1,4-Manp, 1,4 Glcp, 1,4,6-Manp and 1-Glcp. Hematoxylin and Eosin (HE) staining and immunohistochemistry analysis showed that cDHP can increase alveolar number, thicken alveolar wall, inhibit pulmonary bulla formation and decrease inflammatory cell infiltration as compared to the model group. ELISA determination revealed that cDHP can inhibit CS-induced enhancement in TNF-alpha and IL-1beta secretion in serum and lung. These results suggested that cDHP can resist CS-induced lung inflammation. Further, the phosphorylation analysis of p65, IkappaB, p38 and JNK as well as the DNA binding activity analysis of NF kappaB and AP-1 implied that the anti-inflammation function of cDHP is mediated via regulating NF-kappaB and MAPK signaling. PMID- 29580412 TI - Structural characterization of the exopolysaccharides from water kefir. AB - Water kefir is a beverage which is produced by initiating fermentation of a fruit extract/sucrose solution with insoluble kefir grains. Exopolysaccharides that are formed from sucrose play a major role in the kefir grain formation, but the exopolysaccharides in the kefir beverage and the detailed structural composition of the whole kefir grains have not been studied yet. Therefore, kefir grains and the corresponding kefir beverage were analyzed for exopolysaccharides by multiple chromatographic approaches and two-dimensional NMR spectroscopy. Furthermore, different fractionation techniques were applied to obtain further information about the exopolysaccharides. The exopolysaccharide-fraction of the investigated kefir beverage was predominantly composed of O3- and O2-branched dextrans as well as lower amounts of levans. The insoluble dextrans from the kefir grains were mostly O3-branched and contained an elevated portion of 1,3-linked glucose units compared to the soluble dextrans. The structurally different exopolysaccharides in water kefir suggest the involvement of multiple bacteria. PMID- 29580413 TI - Conductive nanostructured materials based on poly-(3,4-ethylenedioxythiophene) (PEDOT) and starch/kappa-carrageenan for biomedical applications. AB - Smart electroactive biomaterials are sought to allow the direct delivery of electrical, electrochemical and electromechanical signals to biological tissues. Specifically, poly-(3,4-ethylenedioxythiophene) (PEDOT) is a polymer of special interest attending to its biocompatibility, tuneable electrical conductivity and processing versatility. In this work, nanostructured PEDOT was synthesized using starch/kappa-carrageenan aerogels as templates. kappa-carrageenan biopolymer acted as doping agent of the conductive polymer to enhance the biocompatibility and the electrical response. The physicochemical, morphological, mechanical and electrical properties of the nanostructured PEDOT and templates were characterized. The incorporation of kappa-carrageenan to the nanostructured materials resulted in an increase in the compressive strength of ca. 40% and a decrease in the electrical impedance of one order-of-magnitude. The synergistic combination of the inherent electrical properties of the PEDOT, the advantageous features of kappa-carrageenan as doping agent and the porous morphology of the aerogel template resulted in electroactive PEDOT nanostructures with relevant properties for biomedical applications. PMID- 29580414 TI - Natural gum-type biopolymers as potential modified nonpolar drug release systems. AB - In this work, the relationship between surface properties and drug release mechanism from binary composition tablets formed by quetiapine fumarate and biopolymer materials was studied. The biopolymers correspond to xanthan and tragacanth gums, which are projected as modified drug release systems. The surface studies were carried out by the sessile drop method, while the surface free energy (SFE) was determinate through Young-Dupree and OWRK semi-empirical models. On the other hand, the drug release studies were performed by in vitro dissolution tests, where the data were analyzed through kinetic models of zero order, first order, Higuchi, and Korsmeyer-Peppas. The results showed that depending on the type and the proportion of biopolymer, surface properties, and the drug release processes are significantly affected, wherein tragacanth gum present a usual erosion mechanism, while xanthan gum describes a swelling mechanism that controls the release of the drug. PMID- 29580415 TI - The novel application of chitosan: Effects of cross-linked chitosan on the fire performance of thermoplastic polyurethane. AB - In this paper, a novel flame retardant (ACS) was prepared by crosslinking chitosan with bis-(4-formylphenyl)-phenyl-phosphonate (ABPO). ACS in association with ammonium polyphosphate (APP) and organic modified montmorillonite (OMMT) were used to prepare flame retardant thermoplastic polyurethane (TPU) composite through melt blending. For the TPU sample containing 10% flame retardants, the limiting oxygen index was increased from 20.8 to 29.0%, the vertical burning (UL 94) rating was upgraded from no rating to V-0, and the peak heat release rate was decreased from 1090 to 284 kW/m2. The thermal gravity analysis (TGA) indicated that ACS had excellent char formation ability and could greatly enhance the thermal stability of TPU. The tensile strength and elongation at break for flame retardant sample could reach 16.5 MPa and 1443% respectively. PMID- 29580416 TI - Fabrication of calcium phosphate-loaded carboxymethyl cellulose non-woven sheets for bone regeneration. AB - Calcium phosphate-loaded carboxymethyl cellulose non-woven sheets (CMC/CaP sheet) were fabricated and their potential to induce in vitro osteoblast differentiation and in vivo bone regeneration were investigated. The CMC/CaP sheets were prepared by alternately soaking protonated-CMC non-woven sheets in CaCl2 and Na2HPO4 aqueous solutions. Because of its slow water uptake rate, the protonated-CMC was successfully loaded with a mixed phase of brushite and hydroxyapatite. In vitro, the CMC/CaP sheet induced osteoblast differentiation of human mesenchymal stromal cells (hMSCs), as shown by calcification and the upregulation of osteoblast marker genes. In absence of CaP, hMSCs on the CMC sheet had enhanced expression of alkaline phosphatase (ALP) only, indicative of early osteoblast differentiation. Finally, bone regeneration by the CMC/CaP sheet was demonstrated in a mouse calvarial defect model, based on micro-computed tomography (micro-CT), Masson's trichrome staining, and immunostaining for osteoblast markers. Cells expressing the transcription factor Sp7/Osterix, which is essential for osteoblast differentiation, were detected around the new bone. The combined effect of CMC and CaP enhanced osteoblast differentiation and the CMC/CaP non woven sheet was found to be an easy-to-handle and flexible scaffold for bone regeneration. PMID- 29580417 TI - Grafting polycaprolactone diol onto cellulose nanocrystals via click chemistry: Enhancing thermal stability and hydrophobic property. AB - Hydrophobic and thermally-stable cellulose nanocrystals (CNCs) were synthesized by polycarpolactone diol (PCL diol) grafting via click chemistry strategy. The synthesis was designed as a three-step procedure containing azide-modification of CNCs, alkyne-modification of PCL diol and sequent copper(I)-catalyzed azide alkyne cycloaddition reaction. The structure of azide-modified CNCs and alkyne modified PCL diol, the structure, hydrophobic ability and thermal stability of click products CNC-PCL were characterized. FTIR, XPS and H1 NMR results indicated a successful grafting of the N3 groups onto the CNCs, synthesis of PCL diol-CCH, and formation of the CNC-PCL material. CNC-PCL had enhanced dispersion in the non polar solvent chloroform owing to the well-maintained microscale size and PCL induced hydrophobic surface. The thermal stability of CNC-PCL was largely increased due to the grafting of thermally-stable PCL. This work demonstrates that click chemistry is an attractive modification strategy to graft CNCs with polyester chains for further potential application in polymer composites. PMID- 29580418 TI - Structure of water in hybrid cellulose acetate-silica ultrafiltration membranes and permeation properties. AB - Hybrid cellulose acetate (CA) silica (SiO2) (CA/SiO2) membranes were synthesized by promoting the in situ condensation between silanols from the SiO2 precursor and the COH or acetate groups from the CA polymer. For all the CA/SiO2 membranes, the ATR-FTIR peak assigned to (SiOC) proves the hybrid condensation reaction and confirms the synthesis of monophasic hybrid membranes. ATR-FTIR shows the presence of uncondensed highly reactive SiOH species, in membranes with silica contents higher than 20 mol%. Together with RMN studies, results show molecular water strongly hydrogen-bonded with SiOH groups, yielding a drastic decrease in the membrane hydraulic permeability, from 57 to 10 kg/h/m2/bar. The incorporation of 5 and 10 mol% of silica increased the hydraulic permeability from 32 to 82 kg/h/m2/bar when compared to the CA membrane.

AB - The purpose of this study was to develop an oral nanocarrier as budesonide delivery system and to evaluate its therapeutic potential for inflammatory bowel disease (IBD). The nanoparticles (NPs) based on an amphiphilic inulin polymer with 4-aminothiophenol (ATP) grafted onto carboxymethyl inulin (CMI) were prepared. The particle sizes were about 210.18 nm and had the obvious pH/redox sensitive swelling transitions. The drug-release study of NPs <-- >in vitro showed a low release rate (about 45 wt%) in GSH-free media, whereas high release rate (about 80 wt%) in the media containing 20 mM GSH, exhibiting a redox responsive property. Further in vivo experiments found the NPs tended to accumulate in inflamed sites, and exerted excellent therapeutic efficacy in comparison to drug suspension in colitis mice model. All the results demonstrated that the redox-sensitive NPs, based on amphiphilic inulin, may be used as colon targeted drug delivery for the treatment of IBD. PMID- 29580420 TI - Design of amphoteric chitosan flocculants for phosphate and turbidity removal in wastewater. AB - An amphoteric flocculant (CMC-CTA) was synthesized by grafting 3-chloro-2 hydroxypropyl trimethylammonium chloride onto carboxymethyl chitosan (CMC). The turbidity and orthophosphate (Pi) removal properties of chitosan (CHI), CMC, and CMC-CTA were compared in the presence (and absence) of FeCl3 coagulant. At a fixed FeCl3 dosage, the effects of flocculant dosage, pH and settling time were evaluated. Turbidity removal (%) and optimal dosage (FeCl3; mg/L) was determined: CMC-CTA (95.8%;5), CHI (88.8%;7.0) and CMC (68.8%;9.0). The corresponding Pi removal (%) and dosage (mg/L) are listed: (93.4%;10), (90.6%;10), and (67.4%;5). Optimal turbidity and Pi removal occurred at pH 4, where CMC-CTA had greater efficiency over CMC and CHI. The turbidity removal kinetics was described by the pseudo-second-order model, while Pi removal followed the pseudo-first-order model. The removal process involves cooperative Coulombic interactions between the biopolymer/Fe(III)/Pi and/or kaolinite colloids, along with polymer bridging effects. PMID- 29580421 TI - Facile hydrothermal synthesis of Fe3O4@cellulose aerogel nanocomposite and its application in Fenton-like degradation of Rhodamine B. AB - A magnetic cellulose aerogel-supported Fe3O4 nanoparticles composite was designed as a highly efficient and eco-friendly catalyst for Fenton-like degradation of Rhodamine B (RhB). The composite (coded as Fe3O4@CA) was formed by embedding well dispersed Fe3O4 nanoparticles into the 3D structure of cellulose aerogels by virtue of a facile and cheap hydrothermal method. Comparative studies indicate that the RhB decolorization ratio is much higher in co-presence of Fe3O4 and H2O2 than that in presence of Fe3O4 or H2O2 only, revealing that the Fe3O4@CA catalyzed Fenton-like reaction governed the RhB decolorization process. It was also found that almost 100% RhB removal was achieved in the Fenton-like system. Moreover, the composite exhibited higher catalytic activity than that of the individual Fe3O4 particles. In addition, the Fe3O4@CA catalyst retained ~97% of its ability to degrade RhB after the six successive degradation experiments, suggesting its excellent reusability. All these merits indicate that the green and low-cost catalyst with strong magnetic responsiveness possesses good potential for H2O2-driven Fenton-like treatment of organic dyestuff wastewater.

AB - Wound dressings are designed to support the wound bed and protect it from the factors that may delay or impede its healing such as contaminations and moisture loss, thereby facilitating and accelerating the healing process. The materials used to prepare wound dressings include natural and synthetic polymers, as well as their combinations, in the forms of films, sponges and hydrogels. Polysaccharides are naturally-occurring polymers that have been extensively used as wound dressing materials. Homopolysaccharides are a class of polysaccharides consist of only one type of monosaccharide. The current review intends to overview the studies in which wound dressings from naturally-occurring polymers, based on homopolysaccharides, were prepared and evaluated. Homopolysaccharides such as cellulose, chitosan, chitin, pullulan, starch and beta-glucan were considered. PMID- 29580423 TI - A novel enzymatic approach to nanocrystalline cellulose preparation. AB - In this work, conditions for an enzymatic pretreatment prior to NCC isolation from cotton linter were assessed. Different cellulase doses and reaction times were studied within an experimental design and NCC were obtained. At optimal enzymatic conditions (20U, 2 h), a total yield greater than 80% was achieved and the necessary enzymatic treatment time was reduced 90%. Different intensities of enzymatic treatments led to proportional decreases in fiber length and viscosity and also were inversely proportional to the amount of released oligosaccharides. These differences within fibers lead to quantitative differences in NCC: increase in acid hydrolysis yield, reduction of NCC surface charge and crystallinity increase. Benefits produced by enzymatic treatments did not have influence over other NCC characteristics such as their sulfur content (~1%), size (~200 nm), zeta potential (~-50 mV) or degree of polymerization (~200). Evidence presented in this work would reduce the use of harsh sulfuric acid generating a cleaner stream of profitable oligosaccharides.

AB - Environmental concerns have led to extensive research for replacing polymer-based food packaging with bio-nano-composites. In this study, incorporation of nano cellulose into gelatin and starch matrices is investigated for this purpose. Chitosan is used to improve mechanical, anti-fungal and waterproof properties. Experiments are designed and analyzed using response surface methodology. Nano Cellulose is synthesized via acid hydrolysis and incorporated in base matrices through wet processing. Also, tensile strength test, food preservation, transparency in visible and UV and water contact angle are performed on the nano composite films. DSC/TGA and air permeability tests are also performed on the optimal films. The results show that increasing nano-cellulose composition to 10% leads to increase the tensile strength at break to 8121 MN/m2 and decrease the elongation at break. Also, increasing chitosan composition from 5% to 30% can enhance food preservation up to 15 days. PMID- 29580426 TI - A new biodegradable sisal fiber-starch packing composite with nest structure. AB - A new completely biodegradable sisal fiber-starch packing composite was proposed. The effects of fiber content and alkaline treatment on the cushioning property of the composites were studied from energy absorption efficiency, cellular microstructure and compatibility between fiber and starch. With increasing fiber content, the nest structure of composites becomes dense first and then loosens, resulting in initial enhancement and subsequent weakening of the cushioning property of the composites. The composite with 4:13 mass ratio of fiber and thermoplastic starch (TPS) exhibit the optimal cushioning property. Alkaline treatment increases the compatibility between sisal fiber and TPS, promotes the formation of dense nest structure, thereby enhances the cushioning property of the composites. After biodegradability tests for 28 days, the weight loss of the composites was 62.36%. It's found that the composites are a promising replacement for expandable polystyrene (EPS) as packing material, especially under large compression load (0.7-6 MPa).

AB - The over- and inefficient release of antibiotics from common delivery systems causes the development of drug-resistant bacteria. In the present work, methoxy poly(ethylene glycol)-poly(epsilon-caprolactone)-chitosan/montmorillonite (MPC/MMT) hybrid multilayer films were constructed for bacterial infections and pH-dependent release of the hydrophobic drug triclosan (TCA). The thickness of the (MPC-T/MMT)10 multilayer films was 384.4 +/- 26.5 nm, and the TCA loading dosage was 2.4 MUg/cm2. Staphylococcus aureus, Escherichia coli and Staphylococcus epidermidis were used in the antibacterial tests. pH responsive TCA release from the prepared multilayer films was examined by measuring the bactericidal activity of the films after immersion in PBS (pH 7.4) or MES (pH 5.5) and zone of inhibition on nutrient agar. In vitro bacterial shake-flask, zone of inhibition and live/dead staining results demonstrated the high sterilization efficiency of the films. Furthermore, cell biocompatibility measurements toward L929 fibroblasts and human lens epithelial cells showed no adverse effects of the multilayer film. PMID- 29580428 TI - Effects of sodium salt types on the intermolecular interaction of sodium alginate/antarctic krill protein composite fibers. AB - Sodium alginate (SA) and antarctic krill protein (AKP) were blended to fabricate the SA/AKP composite fibers by the conventional wet spinning method using 5% CaCl2 as coagulation solution. The sodium salt was added to the SA/AKP solution to adjust the ionization degree and intermolecular interaction of composite system. The main purpose of this study is to investigate the influences of sodium salt types (NaCl, CH3COONa, Na2SO4) on the intermolecular interaction of SA/AKP composite fibers. The intermolecular interaction, morphology, crystallinity, thermal stability and mechanical properties of SA/AKP composite fibers were analyzed by fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), x-ray diffraction (XRD), thermogravimetric analysis (TGA). The results show that the types of sodium salt have obvious influences on the content of both beta-sheet, intermolecular hydrogen bond, breaking strength and surface morphology in SA/AKP composite fibers, but have a negligible effect on the crystallinity and thermal stability.

AB - There has been growing interest in the use of nanocellulose-based substrate for surface-enhanced Raman spectroscopy (SERS) applications. This study aimed to use cellulose nanofibers (CNF) to develop novel CNF-based nanocomposite as a SERS substrate. CNF were cationized with ammonium ions and then interacted with citrate-stabilized gold nanoparticles (AuNPs) via electrostatic attraction to form uniform nanocomposites. The CNF-based nanostructures were loaded with AuNPs that were firmly adhered on the CNF surfaces, providing a three-dimensional plasmonic SERS platform. A Raman-active probe molecule, 4-aminothiophenol, was selected to evaluate the sensitivity and reproducibility of CNF-based SERS substrate. The intensity of SERS spectra obtained from CNF/AuNP nanocomposite was 20 times higher than that from the filter paper/AuNP substrate. The SERS intensity map demonstrates good uniformity of the CNF/AuNP substrate. CNF/AuNP nanocomposites were used in rapid detection of thiram in apple juice by SERS and a limit of detection of 52 ppb of thiram was achieved. These results demonstrate that CNF/AuNP nanocomposite can be used for rapid and sensitive detection of pesticides in food products.

AB - Patho-physiologies related to skin are diverse in nature such as burns, skin ulcers, atopic dermatitis, psoriasis etc. which impose severe bio-medical problems and thus enforce requirement of new and healthy skin prepared through tissues engineering methodologies. However, fully functional and biodegradable matrix for attachment, growth, proliferation and differentiation of the relevant cells is not available. In the present study, we introduce a set of hydrogels synthesized by incorporation of a synthetic monomer (Hydroxyethlmethacryate) with a semi-synthetic polymer backbone (carboxy methyl tamarind, CMT) in different mole ratios. We termed these materials as CMT:HEMA based hydrogels and these were characterized by different physico-chemical techniques, namely by X-Ray Diffraction, SEM and Dynamic Light Scattering. Biocompatibility studies with HaCaT, NIH-3T3 and mouse dermal fibroblasts confirm that this material is biocompatible. MTT assay further confirmed that this material does not have any cytotoxic effects. Assays for mitochondrial functionality such as ATP assay and mitochondrial reactive oxygen (ROS) generation also suggest that this material is safe and does not have any cytotoxicity. Hemolytic assay with red blood cells and acute skin irritation test on SD Rats confirmed that this material is suitable for ex-vivo application in future. We suggest that this hydrogel is suitable for in-vivo applications and may have clinical and commercial importance against skin disorders.

AB - Cellulose nanocrystals (CNCs) are nature-resourced nanoparticles and have been widely used to improve performance of biodegradable polyesters. Two types of CNCs respectively prepared by sulphuric acid hydrolysis (aCNCs) and ammonium persulfate oxidation (oCNCs) processes were incorporated into poly(butylene adipate) (PBA) matrix to regulate its crystallization behavior and enzymatic degradation performance. Thermal and X-ray diffraction analysis revealed that both aCNCs and oCNCs could promote the crystallization ability and lamellar thickening of alpha-form PBA, while oCNCs showed stronger promotion than aCNCs. Optical morphology study indicated that both two types of CNCs enhanced the nucleation ability of PBA. Furthermore, the mechanism of crystallization promotion of CNCs on PBA was further discussed and attributed to the "memory effect" in the melt state of PBA/CNCs composites, which was originated from the hydrogen-bonding interaction between CNCs and PBA chains. The enzymatic degradation testing proved that CNCs could slower down degradation rate of PBA and PBA/oCNCs composites possessed lower degradation rate than PBA/aCNCs composites.

The goal of post-treatment imaging is to identify relapse prior to clinical symptoms, when the burden of disease is lower and the possibility of effective salvage therapy and cure are greater. However, little data exist to support the performance of surveillance imaging after completion of treatment, with the vast majority of studies suggesting there is no clinical benefit to surveillance imaging in asymptomatic patients. Ongoing efforts seek to identify a subset of patients with a higher risk of relapse that might benefit from surveillance imaging, though financial and other costs associated with imaging are non negligible and must be considered. Here we summarize the current data regarding post-treatment surveillance imaging in lymphoma. PMID- 29580432 TI - Surveillance imaging following definitive radiotherapy for non-small cell lung cancer: What is the clinical impact? AB - Lung cancer is the leading cause of cancer death worldwide. Recurrence rates at all stages are high, but evidence-based post-treatment surveillance imaging strategies to detect recurrence are poorly defined, and salvage options are frequently limited. A number of national and international oncology guidelines address post-treatment imaging, but are largely based on low-level, retrospective evidence because of a paucity of high-quality data, particularly in regard to cost-effectiveness and quality-of-life endpoints. Given the lack of randomized data addressing appropriate surveillance imaging modality and interval following definitive treatment of lung cancer, there remains an unmet clinical need. Meaningful surveillance endpoints should include the financial impact, patient quality-of-life outcomes, and access-to-care issues associated with intensive follow-up to ensure that guidelines reflect quality and sustainability. A need for prospective randomized data on the subject of imaging surveillance after definitive local therapy remains an unmet need, and an opportunity for collaboration and further research. PMID- 29580434 TI - Surveillance imaging following treatment of head and neck cancer. AB - Post-treatment surveillance is an important component in the treatment of head and neck cancers, especially as the proportion of human papilloma virus-positive cancers increases. Early detection of recurrences or second malignancies can increase success and minimize the toxicity of salvage treatment. Unfortunately, there are no consensus guidelines on the frequency and modality of post-treatment imaging. Computed tomography, ultrasound, magnetic resonance imaging and positron emission tomography-computed tomography (PET-CT) all have unique advantages and disadvantages when used as surveillance imaging. There is evidence that PET-CT may be the most sensitive of these modalities, but further research is needed to show an improvement in patient outcomes. Institutions will benefit most from a surveillance plan that is consistent and tailored to the individualized needs of their patients. This review focuses on the available evidence for different imaging modalities and general guidelines for developing an institution-specific practice pattern. PMID- 29580435 TI - Cell-free DNA as a post-treatment surveillance strategy: current status. AB - Circulating tumor DNA (ctDNA) consists of cell-free DNA (cfDNA) fragments that are released from tumor cells into the bloodstream. ctDNA harbors cancer-specific genetic and epigenetic alterations that allow its detection and quantification using a variety of emerging techniques. The promise of convenient non-invasive access to the complex and dynamic molecular features of cancer through peripheral blood has galvanized translational researchers around this topic with compelling routes to clinical implementation, particularly in the post-treatment surveillance setting. Although analysis methods must contend with the small quantities of ctDNA present in most patients, and the relative over-abundance of background cfDNA derived from normal tissues, recent technical innovations have led to dramatic improvements in the sensitivity of ctDNA detection. As a result, ever more studies are investigating the clinical utility of ctDNA for applications in (1) treatment response assessment, (2) identification of emerging resistance mechanisms, (3) minimal residual disease detection, and (4) characterization of clonal heterogeneity and selection. In this review, we describe the detection methods currently used in clinical studies to assess low fractions of ctDNA, as well as their utility in the applications previously described. Finally, we address current limitations that have hampered the clinical implementation of ctDNA analysis for post-treatment surveillance and propose steps that could be made to address them. PMID- 29580436 TI - The Surgical Management of Prostate Cancer. AB - Prostate cancer is a heterogeneous disease with a variable natural history. Therefore, optimal management remains challenging. While many men with newly diagnosed prostate cancer may be candidates for active surveillance, there are others who will benefit from aggressive local therapy. Radical prostatectomy is associated with improvements in cancer-specific mortality, metastasis-free survival, and need for palliative treatments when compared with observation in several randomized controlled trials. Additionally, radical prostatectomy may have some oncologic benefit over radiation therapy. All aggressive therapy for prostate cancer negatively impacts erectile function and urinary continence. The decision for which treatment modality to pursue should incorporate shared decision making and consider cancer risk and severity in addition to patient preferences. PMID- 29580437 TI - Second-line therapy in patients with metastatic castration-resistant prostate cancer with progression after or under docetaxel: A systematic review of nine randomized controlled trials. AB - Treatment decisions are challenging in patients with metastatic castration resistant prostate cancer with progression after or under docetaxel. The current review systematically searched the published literature on all treatment options, and assessed the risk of bias and quality of evidence. It found the best available evidence for effective prolongation of overall survival and progression free survival for abiraterone acetate plus prednisone versus placebo plus prednisone and enzalutamide versus placebo. Other treatment modalities could be beneficial for individual patients by taking into consideration the: selection criteria of the randomized clinical trials, risk of bias, subgroup analyses, and quality of life and adverse events. Further research is needed to determine the sequence, timing asnd combination of different treatments. PMID- 29580438 TI - "Mind the Gap" Revisited.

AB - OBJECTIVE: The objective of this study was to discern the relationship between state-level structural racism and Black-White disparities in police shootings of victims not known to be armed. METHODS: Using a Poisson regression, we evaluated the effect of structural racism on differences between states in Black-White disparities in fatal police shootings involving victims not known to be armed during the period from January 1, 2013 through June 30, 2017. We created a state racism index, which was comprised of five dimensions: (1) residential segregation; and gaps in (2) incarceration rates; (3) educational attainment; (4) economic indicators; and (5) employment status. RESULTS: After controlling for numerous state-level factors and for the underlying rate of fatal shootings of black victims in each state, the state racism index was a significant predictor of the Black-White disparity in police shooting rates of victims not known to be armed (incidence rate ratio: 1.24; 95% confidence interval, 1.02-1.50). For every 10-point increase in the state racism index, the Black-White disparity ratio of police shooting rates of people not known to be armed increased by 24%. CONCLUSION: These findings suggest that structural racism is an important predictor of the Black-White disparity in rates of police shootings of unarmed victims across states. PMID- 29580444 TI - Medical Simulation as a Vital Adjunct to Identifying Clinical Life-Threatening Gaps in Austere Environments. AB - BACKGROUND: Maternal mortality and morbidity are major causes of death in low resource countries, especially those in Sub-Saharan Africa. Healthcare workforce scarcities present in these locations result in poor perioperative care access and quality. These scarcities also limit the capacity for progressive development and enhancement of workforce training, and skills through continuing medical education. Newly available low-cost, in-situ simulation systems make it possible for a small cadre of trainers to use simulation to identify areas needing improvement and to rehearse best practice approaches, relevant to the context of target environments. METHODS: Nurse anesthetists were recruited throughout Sierra Leone to participate in simulation-based obstetric anesthesia scenarios at the country's national referral maternity hospital. All subjects participated in a detailed computer assisted training program to familiarize themselves with the Universal Anesthesia Machine (UAM). An expert panel rated the morbidity/mortality risk of pre-identified critical incidents within the scenario via the Delphi process. Participant responses to critical incidents were observed during these scenarios. Participants had an obstetric anesthesia pretest and post-test as well as debrief sessions focused on reviewing the significance of critical incident responses observed during the scenario. RESULTS: 21 nurse anesthetists, (20% of anesthesia providers nationally) participated. Median age was 41 years and median experience practicing anesthesia was 3.5 years. Most participants (57.1%) were female, two-thirds (66.7%) performed obstetrics anesthesia daily but 57.1% had no experience using the UAM. During the simulation, participants were observed and assessed on critical incident responses for case preparation with a median score of 7 out of 13 points, anesthesia management with a median score of 10 out of 20 points and rapid sequence intubation with a median score of 3 out of 10 points. CONCLUSION: This study identified substantial risks to patient care and provides evidence to support the feasibility and value of in-situ simulation-based performance assessment for identifying critical gaps in safe anesthesia care in the low-resource settings. Further investigations may validate the impact and sustainability of simulation based training on skills transfer and retention among anesthesia providers low resource environments. PMID- 29580445 TI - Health Literacy (HL) & Health-Related Quality of Life (HRQL) Among Minority Men. AB - Health literacy remains a key factor in the continuance of health disparities in our society as health related quality of life can be negatively affected by limited health literacy. This study explores how limited health literacy among minority men, attending a community health fair, correlates with their health related quality of life. Findings reflect that minority men who possess lower levels of health literacy experience lower self-reported quality of life. Directions for healthcare providers, community health educators and future research approaches are provided. PMID- 29580446 TI - A Little Effort Can Withstand the Hardship: Fielding an Internet-Based Intervention to Prevent Depression among Urban Racial/Ethnic Minority Adolescents in a Primary Care Setting. AB - BACKGROUND: This study explored the implementation of Chicago Urban Resiliency Building (CURB), a randomized clinical trial designed as an Internet-based primary care depression prevention intervention for urban African American and Latino adolescents. METHODS: We utilized a mixed methods analysis to explore four aims. First, we estimated the percent of at-risk adolescents that were successfully screened. Second, we examined clinic site factors and performance. Third, primary care providers (n = 10) and clinic staff (n = 18) were surveyed to assess their knowledge and attitudes about the intervention. Fourth, clinic staff (nursing and medical assistant) interviews were analyzed using thematic analysis to gather perspectives of the implementation process. RESULTS: We found that the estimated percent of at-risk adolescents who were successfully screened in each clinic varied widely between clinics with a mean of 14.48%. Daily clinic communication was suggestive of greater successful screening. Feasibility of screening was high for both primary care providers and clinic staff. Clinic staff exit interviews indicated the presence of community barriers that inhibited successful implementation of the intervention. CONCLUSION: This study shares the challenges and successes for depression screening and implementing Internet-based mental health interventions for urban racial/ethnic minority adolescents in primary care settings. PMID- 29580447 TI - Is Unsedated Colonoscopy Gaining Ground Over Sedated Colonoscopy? AB - Colorectal cancer (CRC) is a prevalent cancer with high global incidence and a leading cause of cancer death worldwide. CRC screening is important for early cancer detection and prevention. Most premalignant adenomas can be identified and removed before they become malignant. Colonoscopy plays a vital role in reducing the risk for developing CRC. Although screening programs with colonoscopy have been implemented in many countries and considered beneficial for a number of people, this technique is generally associated with anxiety, embarrassment, pain, and discomfort, resulting in lack of adherence to the recommended screening guidelines. In the US, colonoscopy is mostly performed under sedation, thereby causing amnesia and analgesia. In contrast to sedated colonoscopy, which has been associated with some disadvantages, unsedated colonoscopy exhibits advantages and has been preferred over sedated colonoscopy in numerous cancer centers worldwide. This review enumerates the features of sedated and unsedated colonoscopy with the use of the current relevant evidence-based literature. Unsedated colonoscopy can be a reasonable option for routine and unscheduled CRC screening. PMID- 29580448 TI - Hospital Admissions, Mortality and Comorbidities Among New York State Sickle Cell Patients, 2005-2013. AB - Analyses of administrative and large data sources in Sickle Cell Disease (SCD) can answer questions not suitable for prospective study but have been hampered by lack of validated methods to adjust for individual comorbidities and lack of baseline utilization data over time. We sought to develop a database to characterize inpatient SCD care across New York State and generate a re-weighted sickle-cell specific Charlson Comorbidity index (S-CCI) for use in future large data SCD research. We identified 18,541 individual SCD patients admitted to New York State hospitals between 2005 and 2013 from the SPARCS database. We present data from both a randomly selected derivation cohort, used to develop the S-CCI and a validation cohort, The S-CCI resulted in small improvements in model fit and discrimination while using fewer covariates, allowing a more parsimonious model. Despite being the most common comorbidity, chronic pulmonary disease was not predictive of mortality. Mortality per hospitalization was 0.61%. Many patients (32%) were admitted only once during the nine year period. However, the majority was admitted more frequently with over 15% of patients being admitted more than once per year. PMID- 29580449 TI - Medical Students Rate Black Female Peers as Less Socially Connected. AB - BACKGROUND: Social and cultural outcomes are critically important in medical education. A large medical school located in the United States implemented a learning community model intended to promote social and cultural growth among its medical students. The purpose of this study was to evaluate the degree to which medical students from the same peer cohort were socially connected across racial and sex groups. METHODS: Because most assessments involving social and cultural outcomes involve self-reported data of a personal nature, the possibility of social desirability bias is increased. To mitigate this threat, this study utilized a novel method for measuring medical students social connectedness by having peers in one's advisory college provide social connectedness ratings about one another. RESULTS: While surface level results did not reveal any significant differences, a closer inspection of data revealed Black females were less socially connected with medical student peers from their cohort than other peer groups. DISCUSSION: Possible explanations for this are discussed. Future research should continue to investigate the experiences of Black females in medical schools so as to better understand the needs of this important and valuable subpopulation of students. PMID- 29580450 TI - Opioid Utilization by Pregnant Women with Sickle Cell Disease and the Risk of Neonatal Abstinence Syndrome. AB - BACKGROUND: Pregnant women with sickle cell disease (SCD) are at increased risk of maternal and fetal complications. There are limited data on the outcome of the treatment of VOCs with opioids in relation to neonatal complications during pregnancy. METHODS: This is a retrospective cohort study of women with SCD from January 1999 to December 2008. Women with SCD were identified by ICD-9 codes and matched 2:1 to a control group of women on methadone for opioid dependence. The primary outcome was the rate of neonatal abstinence syndrome (NAS). Secondary outcomes included the mean NAS score prior to treatment and the length of treatment. Statistical analysis was performed using SPSS. RESULTS: Twenty-one women with SCD who delivered a total of 23 neonates were included. The rate of NAS among infants born to women with SCD who were treated with opioids at any time was 22% compared to 54% in the methadone controls (p = .010). The rate of NAS was 27% among infants born to women taking opioids daily compared to 54% in the methadone control group (p = .062). CONCLUSIONS: Neonates born to women with SCD who are treated with daily opioids are at a similar risk for developing NAS as those born to mothers on methadone for opioid dependence. Neonates born to women with SCD treated with episodic opioids are at a significantly lower risk for developing NAS than those born to women on methadone for opioid dependence. PMID- 29580451 TI - Racial Differences in Heart Age and Impact on Mortality. AB - BACKGROUND: Heart age is an estimate of the age of a person's cardiovascular system given their cardiovascular disease (CVD) risk factors. The difference between a person's chronological age and heart age (excess heart age) represents their added CVD risk. OBJECTIVE: To examine racial differences in excess heart age and whether race impacts the association between excess heart age and CVD mortality. METHODS: This analysis included 5110 participants (2449 non-Hispanic white, 1287 non-Hispanic black, and 1374 Mexican-American) from the NHANES III who were free of CVD. Heart age was calculated using the sex-specific non laboratory-based Framingham risk prediction functions. Multivariable Cox proportional-hazards regression models were used to evaluate the relationship (overall and by race) between excess heart age and CVD mortality. RESULTS: Mean excess heart age was greatest in non-Hispanic blacks (13.0 years), followed by Mexican-Americans (10.5 years), and non-Hispanic whites (8.5 years); p < 0.001 for pairwise differences. Over a mean follow-up of 13.0 years, 394 CVD deaths occurred. Each 10 years of excess heart age was associated with 65% increased risk of CVD mortality (HR, 95% CI: 1.65, 1.53-1.78). This association was stronger in non-Hispanic whites (1.83, 1.63-2.02) compared to non-Hispanic blacks (1.50, 1.29-1.72) and Mexican American (1.60, 1.33-1.87), interaction p = 0.065. CONCLUSIONS: Compared to non-Hispanic whites, non-Hispanic blacks and Mexican Americans have more excess heart age, but the risk of CVD death for the same level of excess heart age appears more pronounced in non-Hispanic whites. Further investigation is needed to show the usefulness of these findings in directing future efforts and resource allocation for reduction of health disparities between ethnic groups. PMID- 29580452 TI - Effect of Age, Gender, and Sun Exposure on Ethnic Skin Photoaging: Evidence Gathered Using a New Photonumeric Scale. AB - BACKGROUND: African-Americans are less affected by photoaging than lighter skin individuals. Although scales for photoaging have been developed for Caucasians and Asians, no scale exists for African-Americans. AIM: To develop a photonumeric scale for photoaging and to determine factors that contribute to photoaging in African-Americans. METHODS: Five participants' photographs were selected as standards to create a 9-point photonumeric scale (0 = none, 8 = most severe). Three blinded dermatologists used the scale to grade the remaining participants' photographs. RESULTS: Interrater reliabilities were 0.775 (95% CI: 0.635, 0.880) for trial 1 and 0.832 (0.747, 0.883) for trial 2. Intrarater reliabilities, assessed over a 1 week interval, were 0.863 (0.727, 0.940), 0.928 (0.890, 0.954), and 0.866 (0.739, 0.935) for the three graders, indicating strong agreement. Photoaging scores were then correlated with participants' survey on lifestyle factors, which yielded age as a significant predictor (r = 0.91, p < 0.001). Furthermore, multiple regression model to predict facial photoaging (adjusted R2 = 0.849) selected age (b1 = 0.111, p < 0.001), sun exposure (b2 = 0.206, p = 0.014), and gender (b2 = -0.388, p = 0.063) as the most important variables. CONCLUSIONS: A reliable photonumeric scale for photoaging in African Americans was developed. Age, sun exposure, and male gender were found to be contributory factors to photoaging. PMID- 29580453 TI - "We Would Still Find Things to Talk About": Assessment of Mentor Perspectives in a Systemic Lupus Erythematosus Intervention to Improve Disease Self-Management, Empowering SLE Patients. AB - BACKGROUND: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disorder with significant disparate impact on African American women. The current study sought to highlight how the Peer Approaches to Lupus Self-management (PALS) intervention worked bi-directionally wherein both women with SLE leading the disease self-management program (mentors), and those participants who served as mentees, were empowered toward greater disease self-efficacy. METHODS: Data was captured for this study in two formats from the seven mentors participating in the pilot study: 1) mentor logs and 2) mentor interviews with the principle investigator. This information was then analyzed for themes relating to their experience within the study. RESULTS: We found that empowerment was facilitated by mentors taking their mentorship responsibilities seriously and seeking several avenues for collaboratively developing success with their mentees. Mentors reported that although challenges arose, their desire for success resulted in multiple approaches to be flexible and responsive to the needs of their mentees. Additionally, reciprocity was found to be a vital element of the program. CONCLUSIONS: Key thematic areas supported our ability to demonstrate the usefulness of a peer mentoring program for SLE disease self-management on evoking empowerment through reciprocal relationships among mentors and mentees within our study population. Furthermore the feedback from PALS participants yielded very rich and contextual information that can be used as a thematic guide for developing and refining evidence-based interventions that seek to incorporate empowerment into disease self-management efforts for women suffering from SLE. PMID- 29580455 TI - Development of Rope Connected Life-Saving Equipment for Transferring Numerous People. AB - BACKGROUND: This study is focused on a rapid and safe transfer when there are many people who need rescuing in unapproachable location. Generally, a stretcher, a basket or a mesh drawing is used to transfer injured people or survivors in the emergency rescue, however, it turned out that it takes long time to transfer a number of people with a stretcher and it is difficult to transfer injured people safely with a basket or a mesh drawing. It would expect to transfer many people who need rescuing promptly and harmlessly. METHODS: In this article, Targeted Acceptable Responses to Generated Events of Tasks (TARGETS), an event-based team performance measurement methodology was used to investigate the effects of Mission Oriented Protective Posture (MOPP) on the behavioral processes underlying team performance during simulated rescue tasks while wearing chemical protective equipment. In addition, this study determined which team processes were related to team performance outcomes. Results of six primary analyses indicated that team process performance was not degraded by MOPP 4 on any rescue task and that the team processes critical for successful task performance are task-dependent. RESULTS: As a result, authors have developed a new life-saving equipment. Numerous people who need rescuing can be quickly and safely rescued and transferred to the hospital with it. From a medical point of view, it reduces the risk of secondary damage from transport and helps avoid missing the golden time for first aid caused by delay in transferring emergency patients as numerous people can be transferred safely and quickly. CONCLUSION: The article is due to introduce the equipment which can transfer people who need rescuing promptly and effectively in a situation such as when numerous people need rescuing in the mountain. In a rescue situation such as mountain rescue, rope connected life saving equipment is dropped to the rescue site with a rope from a rescue helicopter and laying down the injured on the life-saving equipment body and equip life-saving equipment to the rope consecutively. In this way, it is expected to transfer the injured rapidly and safely. PMID- 29580454 TI - Characterizing Mobility Limitations Among Older African American Men. AB - This study represents an effort to contribute to the limited body of research on biopsychosocial contextual factors that influence or contribute to mobility limitations for older African American men. Specifically, we were interested in examining associations between socio-demographic, physical and emotional health experiences with mobility limitations. A secondary analysis of 1666 older African American men was performed to investigate socio-demographic, mental and physical health correlates to a specific measures of mobility limitation. In the final model, difficulty with self-care, severe pain interference, and problems with usual activities were most strongly associated with mobility limitations. Men who were married were significantly less likely to experience mobility limitations. Findings highlighted the relationship between mobility limitations and difficulty performing activities of daily living. Additional research should examine the impact of poor emotional health and the buffering effects of marriage on mobility for older African American men, a population at high risk of experiencing disparate health outcomes.

AB - Large yellow croaker (Pseudosciaena crocea) is a popular and nutritious but also highly perishable fish species, with Shewanella baltica being the primary spoilage bacteria during low-temperature storage. Clarifying the factors promoting spoilage will facilitate efforts to predict and control the shelf life of foods. This study focused on spoilage-related genes in two Shewanella baltica strains with different spoilage potentials. Using whole genome sequencing and alignment, three distinguishing genes (torT, cysM and trxB) were identified. Further protein sequence comparison and protein structure modeling revealed possible motifs responsible for the spoilage activity. Moreover, diketopiperazine (DKP) quorum sensing (QS) signaling molecules regulated biofilm formation and spoilage gene expression, indicating a relationship between the QS system, biofilm formation and spoilage potential. Our results suggest that DKPs and spoilage genes are potential targets for developing novel food antiseptics, as well as new markers for fish product spoilage. PMID- 29580466 TI - Integrated combined effects of temperature, pH and sodium chloride concentration on biofilm formation by Salmonella enterica ser. Enteritidis and Typhimurium under low nutrient food-related conditions. AB - Salmonella enterica is a major foodborne bacterial pathogen. This forms biofilms on surfaces and persists, depending on the strain and the environment. The integrative interaction of temperature (T; 13-39 degrees C), pH (5-8) and sodium chloride (NaCl) concentration (0.5-8.5%) on biofilm formation by two S. enterica strains (ser. Enteritidis and Typhimurium) was here evaluated under low nutrient conditions. This was achieved using response surface methodology to model the combined effect of each factor on the response, through mathematical quadratic fitting of the outcomes of a sequence of designed experiments. These last were executed by incubating stainless steel coupons carrying sessile bacteria, for 24 h, in 1:10 diluted tryptone soya broth, under 15 different combinations of three independent factors (T, pH and NaCl). For each strain, a second order polynomial model, describing the relationship between biofilm formation (log CFU/cm2) and the factors (T, pH and NaCl), was developed using least square regression analysis. Both derived models predicted the combined influences of these factors on biofilm formation, with agreement between predictions and experimental observations (R2 >= 0.96, P <= 0.0001). For both strains, the increase of NaCl content restricted their sessile growth, while under low salinity conditions (NaCl < 4%) biofilm formation was favored as pH increased, regardless of T. Interestingly, under low salt content, and depending on the strain, biofilm formation was either favored or hindered by increasing T. Thus, 34.5 and 13 degrees C were the T predicted to maximize biofilm formation by strains Enteritidis and Typhimurium, respectively, something which was also experimentally verified. To sum, these models can predict the interactive influences of crucial food-related factors on biofilm growth of a significant foodborne pathogen towards the efforts to limit its persistence in food industry. PMID- 29580467 TI - Extracts of black garlic exhibits gastrointestinal motility effect. AB - In this studied, extracts of black garlic on the improvement of gastrointestinal function, antioxidant activity, total polyphenols, total flavonoids and total polysaccharides were evaluated. Results showed that the black garlic n-butanol fraction extract (BA) had significantly increased effect within small intestine in vitro, while the ethyl acetate fractions had no significant effect on small intestine in vitro. Increase of 5-HT4 content effectively stimulated the gastrointestinal peristalsis, which enhanced its gastrointestinal tract emptying, and promoted defecation. As for antioxidant activity test, the water extract was more effective in SOD activity test, DPPH radical scavenging rates, ferric reducing antioxidant power and reducing power. In addition, the water fraction was simulated by gastric acid digestion and hydrolysis, and the small intestine was isolated after acid hydrolysis (AW). It was found that the water fraction extract after acid hydrolysis did significantly improve the intestinal contraction rate. In short, extract of black garlic could effectively promote gastrointestinal motility and promote defecation. The active compounds were highly polar ingredients since water extract of black garlic exhibits most significant effect on improving gastrointestinal function. PMID- 29580468 TI - Processed cheese as a polymer matrix composite: A particle toolkit for the replacement of milk fat with canola oil in processed cheese. AB - In this study, we show that the replacement of milk fat with canola oil in a model caseinate-based imitation cheese product to increase its nutritional value can be done by treating processed cheese as a particle filled gel network. Using microscopy, model imitation cheese products with different lipid phases were found to have similar microstructures where fat or oil appears as inert particle fillers in a continuous protein network. Using a texture profile analyzer, we show that the textural properties of model imitation cheese are dependent on the material properties of the inert filler. Addition of rigid particle fillers generally results in greater reinforcement of the matrix (i.e., increased hardness). The addition of oat fiber particles at 5% volume fraction to model cheese containing 51% milk fat and 49% canola oil resulted in a product with similar functionalities (i.e., hardness, oil stability, and meltability) as that of model cheese containing 100% milk fat. The current study therefore shows that the addition of edible non-fat particles for matrix reinforcement can be used as an alternative method for reducing saturated fats in foods while keeping other desirable properties of the product. PMID- 29580469 TI - Comparison of fresh watermelon juice aroma characteristics of five varieties based on gas chromatography-olfactometry-mass spectrometry. AB - Qualitative and quantitative analysis and odor active value (OAV) calculation were applied to identify the aroma-active compounds of fresh watermelon juice in five varieties: Seedless, Jingxin, Lianfa, Qilin, and Texiaofeng. Principal component analysis and cluster analysis were selected to compare the similarity and difference among watermelons juices. Fifty-five volatiles were identified in watermelon juice in five varieties, among which 6 volatiles were identified for the first time in watermelon. (Z)-6-nonenal, (E, Z)-2,6-nonadienal, (E)-2 nonenal, and (E, E)-2,4-nonadienal contributed greater to aroma profiles than alcohols due to lower threshold through odor active values. It was indicated by principal component analysis and cluster analysis that watermelon juices were separated into three groups, Jingxin, Lianfa-Texiaofeng, and Seedless-Qilin, whose characteristic volatiles were aldehydes, alcohols, and ketones respectively. The average distance between JX and the other varieties was higher than that of others through cluster analysis, indicating that the aroma of Jingxin differed from that of the other four varieties greatly. PMID- 29580470 TI - Degradation of carotenoids in dehydrated pumpkins as affected by different storage conditions. AB - The degradation kinetics of carotenoids in dehydrated pumpkins, stored at 4, 25, and 40 degrees C under air or controlled atmosphere conditions (N2), was evaluated using reversed-phase high performance liquid chromatography coupled with diode array and mass spectrometry detectors. The degradations of predominant carotenoids including beta-carotene, alpha-carotene and lutein depended on the storage temperature, the storage duration as well as the presence of oxygen, which was following the first-order kinetics. The temperature dependence of reaction constants were well explained by the Arrhenius relationship. The activation energy (Ea) for carotenoids degradation ranged from 23.69 kJ/mol for lutein in N2-packaged dehydrated pumpkins to 13.82 kJ/mol for beta-carotene in air-packaged samples. Lutein was less degradable than alpha-carotene and beta carotene in dehydrated pumpkins during storage. Higher all-E-carotenoid degradation in N2-packaged dehydrated pumpkins stored at 40 degrees C occurred than that stored at lower temperature under N2 or air storage, and those storage conditions were beneficial to the formation of Z-isomers (e.g., 15-Z-beta carotene and 13-Z-beta-carotene). Storage under N2 at 4 degrees C enhanced the retention of all-E-carotenoids in dehydrated pumpkins. Thus, package atmosphere should be paid more attention during long-term storage.

AB - The addition of xylooligosaccharide (XOS), sodium reduction and flavor enhancers (arginine and yeast extract) on the manufacture of requeijao cremoso processed cheese was investigated. The addition of XOS resulted in a denser and compact structure, with increased apparent viscosity, elasticity (G') and firmness (G*). The addition of XOS and yeast extract improved the rheological and physicochemical properties (decrease in viscosity and particle size and increase in melting rate) and sensory characteristics (improvement in salty and acid taste, greater homogeneity, and lower bitter taste). In addition, a positive effect of arginine was observed in the sensory characteristics of the requeijao cremoso processed cheese, but without improvements in the physicochemical and rheological characteristics. Overall, the XOS addition and sodium reduction proportionated the development of a healthier processed cheese formulation.

AB - In this study the effect of various emulsifiers (whey protein isolate (WPI), Na caseinate, and Tween 20) and thickeners (xanthan and pectin) present in the outer water phase, w2, on oil droplet size and yield of the inner water phase, w1, of (w1/o/w2) double emulsions was investigated. Double emulsions stabilized by Tween 20 had smaller oil droplet sizes and higher yields in comparison to emulsions stabilized by WPI and Na-caseinate. Gelation of the inner water droplets w1 increased yield by 20% for all emulsifiers. Upon the addition of thickeners, the increasing viscosity of the outer water phase, w2, facilitated oil droplet breakup. This resulted in smaller oil droplets and lower yields. When pectin was used as a thickener, in comparison to xanthan, an additional decrease in yield was observed. The yield decreased to values close to zero indicating that all inner water droplets w1 were lost during emulsification. We conclude that type of hydrophilic emulsifier, properties of inner water droplets, viscosity ratio of continuous and dispersed phase, as well as type of thickener influence oil droplet size and yield of w1 phase of double emulsions. This work provides a better understanding of how composition influences the properties of double emulsions and how this can be used to design double emulsions as fat replacers in more complex food systems.

AB - Twenty extended-spectrum beta-lactamase (ESBL)-producing E. coli strains were isolated from imported meat in South Korea. ESBL strains of E. coli were detected in chicken (14/20) more often than in pork (6/20) and beef (0/20); the highest number (12/20) was detected in Brazilian meats. The blaCTX-M genes were predominant in meats from many countries. E. coli from pork imported from France produced the blaCTX-M-58 enzyme, which has never been documented previously in ESBL-producing bacteria from clinical or environmental sources. Additionally, the coexistence of the blaCTX-M-2 and blaOXA-1 enzymes in EC12-5 isolate was found for the first time in an ESBL E. coli isolate. A rare blaCTX-M type, blaCTX-M-25, was found in 40% of ESBL E. coli isolates. Phenotypic susceptibility testing showed that E. coli isolates were resistant to up to eleven antibiotics, including ciprofloxacin. For the first time, a new combination in an integron gene cassette, aacA4-cmlA6-qacEDelta1, was found in an E. coli isolate from poultry imported from Brazil. Three E. coli ST117 isolates, from an avian pathogenic lineage producing CTX-M-94, harbored fimH, fyuA, iutA, papC, rfc, and traT virulence genes and were not susceptible to quinolones. For the first time, rfc and papG virulence factors were detected in ESBL E. coli strains isolated from meat products. Even though E. coli CC21 and CC22 were obtained from meats from the USA and Brazil, respectively, they had a similarity coefficient higher than 99% in rep-PCR and the same MLST type (ST117), phenotypic antibiotic resistance pattern, integron gene (qacEDelta1), and plasmid DNA profile. This study indicates that imported meat products may be a source of ESBL-producing E. coli strains in South Korea.

AB - This work studied the cell transport of peptidase-generated peptides from cowpea bean proteins and their effects on mRNA expression of cholesterol-related genes in intestinal and liver cells. The <=3 kDa hydrolysate was obtained and incubated with Caco-2 intestinal cells using Transwell(r) plates. HepG2 liver cells were incubated with synthetic analogues of peptides (MELNAVSVVHS and MELNAVSVVSH) identified by "de novo" peptide sequencing in the Caco-2 monolayer permeates. The mRNA expression of NPC1L1, ABCA1 and ABCG1 was measured in Caco-2 cells, in the presence or absence of <=3 kDa hydrolysate and the expression of HMGCR, SREBP2, LXRalpha, AMPK1, was determined in the HepG2 cells in the presence or absence of synthetic peptides. Exposure of Caco-2 cells to cowpea <=3 kDa hydrolysate (2.5 and 5 mg/mL) increased ABCG1 expression at 6 h and 12 h. SREBP2, HMGCR and LDLR mRNA levels were reduced in HepG2 cells after 24 h of treatment with MELNAVSVVHS peptide (50 MUM and 100 MUM). These results suggest that MELNAVSVVHS peptide is able to cross intestinal barrier and to modulate genes involved in cholesterol homeostasis. PMID- 29580475 TI - Viscozyme L pretreatment on palm kernels improved the aroma of palm kernel oil after kernel roasting. AB - With an interest to enhance the aroma of palm kernel oil (PKO), Viscozyme L, an enzyme complex containing a wide range of carbohydrases, was applied to alter the carbohydrates in palm kernels (PK) to modulate the formation of volatiles upon kernel roasting. After Viscozyme treatment, the content of simple sugars and free amino acids in PK increased by 4.4-fold and 4.5-fold, respectively. After kernel roasting and oil extraction, significantly more 2,5-dimethylfuran, 2 [(methylthio)methyl]-furan, 1-(2-furanyl)-ethanone, 1-(2-furyl)-2-propanone, 5 methyl-2-furancarboxaldehyde and 2-acetyl-5-methylfuran but less 2-furanmethanol and 2-furanmethanol acetate were found in treated PKO; the correlation between their formation and simple sugar profile was estimated by using partial least square regression (PLS1). Obvious differences in pyrroles and Strecker aldehydes were also found between the control and treated PKOs. Principal component analysis (PCA) clearly discriminated the treated PKOs from that of control PKOs on the basis of all volatile compounds. Such changes in volatiles translated into distinct sensory attributes, whereby treated PKO was more caramelic and burnt after aqueous extraction and more nutty, roasty, caramelic and smoky after solvent extraction. PMID- 29580477 TI - Thermal treatment of skim milk concentrates in a novel shear-heating device: Reduction of thermophilic spores and physical properties. AB - Endospores of thermophilic bacilli are a major concern for producers of dairy powders. In this study, we heat treated 10 different spore suspensions at 110 degrees C in skim milk and skim milk concentrate (36% dry matter) of the species Geobacillus stearothermophilus (10 min) and Anoxybacillus flavithermus (5 min) in a new shear-heating device. The highest log reduction in skim milk concentrate was 3.5. The death behavior of the spores was strain dependent. Particle formation and Maillard reaction were observed. By increasing the shear-rate up to 1500 s-1 the particle size was reduced for both heating times (D90 reduction: 57.4 and 77.0%, respectively). The particle size was lessened by a reduction of dry matter of 27%, compared to 36%. This work emphasizes, that heat treatment of concentrated dairy products represents a technological option to reduce thermophilic spores in skim milk concentrate and powders produced thereof. PMID- 29580476 TI - Correlating the properties of different carioca bean cultivars (Phaseolus vulgaris) with their hydration kinetics. AB - This work explained how the intrinsic properties of beans affects the hydration process. For that, different properties of six cultivars of carioca bean (a variety of common bean) were analyzed to verify the correlation with their hydration kinetics characteristics (hydration rate, lag phase time and equilibrium moisture content), using a Multiple Factorial Analysis (MFA): the chemical composition (starch, protein, lipids, minerals (Mg, P, S, K, Ca, Mn, Fe, Cu, Zn), functional groups from the seed coat analyzed by FT-IR), physical properties (size, 1000 grain weight, seed coat thickness, energy to penetrate the bean) and microstructure. Only few properties correlated with the hydration kinetics characteristics of the studied bean, comprising both composition and structure. The fat content, potassium content, specific surface, and the protein to lipids ratio correlated with the lag phase time, which is related with the seed coat impermeability to water. The necessary energy to perforate the seed coat correlated negatively with the hydration rate. It was concluded that the hydration of beans process is a complex phenomenon and that despite being from the same variety of legume, any change due to agronomic enhancement may affect their hydration process kinetics. PMID- 29580478 TI - Supersaturation of calcium citrate as a mechanism behind enhanced availability of calcium phosphates by presence of citrate. AB - Dissolution of amorphous calcium phosphate (ACP) in aqueous citrate at varying pH has been studied with perspective of increasing availability of calcium from sidestreams of whey protein, lactose and/or cheese production or on development of new functional foods. ACP formed as an initial precipitate in 0.10 mol L-1 equimolar aqueous calcium chloride, sodium citrate, and sodium hydrogenphosphate was used as model for mineral residues formed during milk processing. Upon acidification of the ACP suspension by hydrochloric acid decreasing pH from 6.5 to 4.5, the transformations of ACP occurred through an 8 h period of supersaturation prior to a slow precipitation of calcium citrate tetrahydrate. This robust supersaturation, which may explain increased availability of calcium phosphates in presence of citrate, presented a degree of supersaturation of 7.1 and was characterized by precipitation rates for 0.10 mol L-1 equimolar aqueous calcium chloride, sodium hydrogencitrate, and sodium hydrogenphosphate with pH 5.5, and for 0.10 mol L-1 equimolar aqueous calcium chloride, sodium hydrogencitrate, and sodium dihydrogenphosphate with pH 4.1, with a degree of supersaturation of 2.7. The crystallization processes were similar according to Avrami's model with a half-life for precipitation of approximately 5 h independent of the degree of supersaturation. Ion speciation based on measurement of pH, and total concentrations of calcium, phosphate and citrate, and of conductivity and calcium ion activity during precipitation indicates a low driving force for precipitation with calcium citrate complex dominating at pH 5.5 and calcium hydrogencitrate complex dominating at pH 4.1. Calcium hydrogencitrate is suggested to be the species involved in the crystal growth followed by solid state transformation to calcium citrate tetrahydrate.

AB - Nowadays the higher nutritional value of whole grains compared to refined grains is recognized. In the last decade, there has been a renewed interest in the ancient wheat varieties for producing high-value food products with enhanced health benefits. This study compared two ancient grains, two heritage grains, and four modern grains grown in the same agronomic conditions considering not only their chemical characteristics, but also their biological effects. Whole grain flours were obtained and used to make bread. Bread was in vitro digested, the digesta were supplemented to HepG2 cells, and the biological effects of supplementation were evaluated. In addition, cells previously supplemented with the different digested bread types were then exposed to inflammatory agents to evidence possible protective effects of the pre-treatments. Despite the impossibility to discriminate bread made with different grains based on their chemical composition, results herein reported evidence that their supplementation to cultured cells exerts different effects, confirming the potential health benefits of ancient grains. This research represents an advancement for the evaluation of the apparent positive effects of ancient grains and the formulation of cereal-based products with added nutritional value. PMID- 29580480 TI - Chemical characterization complemented with chemometrics for the botanical origin identification of unifloral and multifloral honeys from India. AB - Chemical fingerprints based on FTIR spectra, phenolics and volatiles were studied for a total of 30 honey types of eight different botanical origin i.e. litchi, neem, ginger, eucalyptus, lemon (unifloral) and Kashmiri white, BR Hills & Pan India honey (Multifloral). Chemometrics based on principal component analysis (PCA) was used as a complementary tool for chemical fingerprint of honey. ATR FTIR had a good predictive capability to discriminate among honey when conjugated with chemometric tools, providing the rapid first-line of classification for honey. The specific phenolic compounds identified were homovanillic acid for neem, zingerone and gingerol for ginger, tricetin for eucalyptus, hesperitin and naringenin for lemon honey. Analysis of volatiles led to identification of odor active compounds such as azadirachtin for neem and zingiberene in ginger honey for the first time, whereas cis-rose oxide for litchi, 2-hydroxycineole for eucalyptus and methyl anthranilate & limonene diol for lemon honey as per previous studies which were well correlated with PCA of phenolics and volatiles. PMID- 29580481 TI - Impact of wall material physicochemical characteristics on the stability of encapsulated phytochemicals: A review. AB - Phytochemicals are plant-derived chemicals that have a number of protective or health-promoting properties. However, their health benefits and thus commercial potential can be restricted due to their instability to environmental factors such as moisture, heat, light, oxygen etc. A common approach to improve stability is via encapsulation whereby the phytochemical is encased inside a wall material, thereby forming a protective barrier between the phytochemical and the external environment. The impact of a wide range of wall materials and their combinations on the stability of various phytochemicals has been studied in the last twenty years. This review focuses on the specific inherent physicochemical characteristics of the wall material as well as the encapsulation process dependant physical characteristics that has shown to have the greatest impact on the stability of encapsulated phytochemicals. The information contained in this review could assist researchers in addressing some of the most important considerations when designing a wall material for increased phytochemical stability. PMID- 29580482 TI - Growth of non-toxigenic Clostridium botulinum mutant LNT01 in cooked beef: One step kinetic analysis and comparison with C. sporogenes and C. perfringens. AB - The objective of this study was to investigate the growth kinetics of Clostridium botulinum LNT01, a non-toxigenic mutant of C. botulinum 62A, in cooked ground beef. The spores of C. botulinum LNT01 were inoculated to ground beef and incubated anaerobically under different temperature conditions to observe growth and develop growth curves. A one-step kinetic analysis method was used to analyze the growth curves simultaneously to minimize the global residual error. The data analysis was performed using the USDA IPMP-Global Fit, with the Huang model as the primary model and the cardinal parameters model as the secondary model. The results of data analysis showed that the minimum, optimum, and maximum growth temperatures of this mutant are 11.5, 36.4, and 44.3 degrees C, and the estimated optimum specific growth rate is 0.633 ln CFU/g per h, or 0.275 log CFU/g per h. The maximum cell density is 7.84 log CFU/g. The models and kinetic parameters were validated using additional isothermal and dynamic growth curves. The resulting residual errors of validation followed a Laplace distribution, with about 60% of the residual errors within +/-0.5 log CFU/g of experimental observations, suggesting that the models could predict the growth of C. botulinum LNT01 in ground beef with reasonable accuracy. Comparing with C. perfringens, C. botulinum LNT01 grows at much slower rates and with much longer lag times. Its growth kinetics is also very similar to C. sporogenes in ground beef. The results of computer simulation using kinetic models showed that, while prolific growth of C. perfringens may occur in ground beef during cooling, no growth of C. botulinum LNT01 or C. sporogenes would occur under the same cooling conditions. The models developed in this study may be used for prediction of the growth and risk assessments of proteolytic C. botulinum in cooked meats. PMID- 29580483 TI - Pre-fermentative cold maceration in presence of non-Saccharomyces strains: Evolution of chromatic characteristics of Sangiovese red wine elaborated by sequential inoculation. AB - Two different Metschnikowia strains (M. pulcherrima MP 346 or M. fructicola MF 98 3) were applied for the first time, during pre-fermentative cold maceration (PCM) in order to enhance the properties and stability of Sangiovese wine color. During the 2014 and 2015 vintages a total of eight wines were produced with 24 h of cold maceration (PCM 24 h) or 72 h (PCM 72 h), respectively. PCM was carried out in presence of MP 346 or MF 98-3 or pectic enzyme (Cuvee Rouge). The sequential inoculation of S. cerevisiae strain was carried out at the end of PCM. After 12 months in the bottle, the MP 346 and MF 98-3 wines contained much higher levels of total flavonoids than the Control sample for both vintages and regardless PCM duration. Moreover, in both vintages only MF 98-3 showed a higher color intensity than the Control sample after 12 months in the bottle. However, neither PCM duration nor the microbial/enzymatic treatment increased the level of anthocyanins at draining off. Both wines produced by the pre-fermentative inoculum with Metschnikowia strains (MP 346 and MF 98-3) retained their red hue, regardless the duration of pre-fermentative and fermentative macerations, while the Control wines were characterized by faster rates of color loss.

PMID- 29580485 TI - Application of Raman spectroscopy and chemometric techniques to assess sensory characteristics of young dairy bull beef. AB - This work aims to develop a rapid analytical technique to predict beef sensory attributes using Raman spectroscopy (RS) and to investigate correlations between sensory attributes using chemometric analysis. Beef samples (n = 72) were obtained from young dairy bulls (Holstein-Friesian and Jersey*Holstein-Friesian) slaughtered at 15 and 19 months old. Trained sensory panel evaluation and Raman spectral data acquisition were both carried out on the same longissimus thoracis muscles after ageing for 21 days. The best prediction results were obtained using a Raman frequency range of 1300-2800 cm-1. Prediction performance of partial least squares regression (PLSR) models developed using all samples were moderate to high for all sensory attributes (R2CV values of 0.50-0.84 and RMSECV values of 1.31-9.07) and were particularly high for desirable flavour attributes (R2CVs of 0.80-0.84, RMSECVs of 4.21-4.65). For PLSR models developed on subsets of beef samples i.e. beef of an identical age or breed type, significant improvements on prediction performances were achieved for overall sensory attributes (R2CVs of 0.63-0.89 and RMSECVs of 0.38-6.88 for each breed type; R2CVs of 0.52-0.89 and RMSECVs of 0.96-6.36 for each age group). Chemometric analysis revealed strong correlations between sensory attributes. Raman spectroscopy combined with chemometric analysis was demonstrated to have high potential as a rapid and non destructive technique to predict the sensory quality traits of young dairy bull beef. PMID- 29580486 TI - Encapsulation of Hibiscus sabdariffa L. anthocyanins as natural colours in yeast. AB - Hibiscus sabdariffa extracts, a rich source of anthocyanin, were subjected to encapsulation in yeast cells. An encapsulation yield (EY) of 208 MUg/100 mg of cells and an encapsulation efficiency (EE) of 27%, were reached after optimisation of the ratios (0.5 g wet yeast cells for 5 ml of anthocyanin extracts at 1 g.L-1) and with 10% of ethanol. The storage stability of encapsulated pigments was investigated in water and buffer pH 1.5 at 5 & 37 degrees C for 10 days and 90 degrees C for 30 min. The percentage of loss of colour was determined by colourimetry assays. The microparticles made of yeast with or without heat treatment exhibited different protecting effects (P < 0.01). At 37 degrees C, the percentage of loss of colour in water was of 2.5% for heat treated and 36.5% for non-treated yeast microparticles, suggesting that yeast enzymes would be responsible for the loss of anthocyanin during storage. These results are confirmed by the percentage of loss of colour which was far lower in conditions of low enzymatic activity: 3.1% at 5 degrees C for non-heat-treated cells in water. The pH of solvent had also an important effect on the degradation of encapsulated anthocyanin; in buffer at pH 1.5 and 37 degrees C with the non heat-treated cells, the degradation decreased strongly to 9.4% compared with 36.5% in water. These results show that yeast cells are a good mean of encapsulation of pigments for a colouring purpose and that they provide anthocyanins a good protection as long as their enzymes are inactivated. PMID- 29580487 TI - Viscoelastic properties of soy protein isolate - pectin blends: Richer than those of a simple composite material. AB - Concentrated soy protein isolate (SPI) - pectin blends acquire fibrous textures by shear-induced structuring while heating. The objective of this study was to determine the viscoelastic properties of concentrated SPI-pectin blends under similar conditions as during shear-induced structuring, and after cooling. A closed cavity rheometer was used to measure these properties under these conditions. At 140 degrees C, SPI and pectin had both a lower G* than the blend of the two and also showed a different behavior in time. Hence, the viscoelastic properties of the blend are richer than those of a simple composite material with stable physical phase properties. In addition, the G'pectin was much lower compared with the G'SPI and G'SPI-pectin upon cooling, confirming that pectin formed a weak dispersed phase. The results can be explained by considering that the viscoelastic properties of the blend are influenced by thermal degradation of the pectin phase. This degradation leads to: i) release of galacturonic acid, ii) lowering of the pH, and iii) water redistribution from the SPI towards the pectin phase. The relative importance of those effects are evaluated. PMID- 29580488 TI - Biocontrol of Listeria monocytogenes in a meat model using a combination of a bacteriocinogenic strain with curing additives. AB - The aim of this work was to evaluate the effect of meat curing agents on the bioprotective activity of the bacteriocinogenic strain, Enterococcus (E.) mundtii CRL35 against Listeria (L.) monocytogenes during meat fermentation. The ability of E. mundtii CRL35 to grow, acidify and produce bacteriocin in situ was assayed in a meat model system in the presence of curing additives (CA). E. mundtii CRL35 showed optimal growth and acidification rates in the presence of CA. More importantly, the highest bacteriocin titer was achieved in the presence of these food agents. In addition, the CA produced a statistical significant enhancement of the enterocin CRL35 activity. This positive effect was demonstrated in vitro in a meat based culture medium, by time-kill kinetics and finally by using a beaker sausage model with a challenge experiment with the pathogenic L. monocytogenes FBUNT strain. E. mundtii CRL35 was found to be a promising strain of use as a safety adjunct culture in meat industry and a novel functional supplement for sausage fermentation, ensuring hygiene and quality of the final product. PMID- 29580489 TI - Plant cells as food - A concept taking shape. AB - Plant cell cultures from cloudberry, lingonberry and stoneberry were studied in terms of their nutritional properties as food. Carbohydrate, lipid and protein composition, in vitro protein digestibility and sensory properties were investigated. Dietary fibre content varied between 21.2 and 36.7%, starch content between 0.3 and 1.3% and free sugar content between 17.6 and 33.6%. Glucose and fructose were the most abundant sugars. High protein contents between 13.7 and 18.9% were recorded and all samples had a balanced amino acid profile. In vitro protein digestion assay showed hydrolysis by digestive enzymes in fresh cells but only limited hydrolysis in freeze-dried samples. The lipid analysis indicated that the berry cells were rich sources of essential, polyunsaturated fatty acids. In sensory evaluation, all fresh berry cells showed fresh odour and flavour. Fresh cell cultures displayed a rather sandy, coarse mouthfeel, whereas freeze dried cells melted quickly in the mouth. All in all the potential of plant cells as food was confirmed. PMID- 29580490 TI - Effect of whey protein isolate films incorporated with montmorillonite and citric acid on the preservation of fresh-cut apples. AB - The objective of this paper was to evaluate the effect of bioactive whey protein isolate/montmorillonite films containing citric acid on the inhibition of enzymatic browning and physicochemical properties in minimally processed apples. Whey protein isolate films incorporated with montmorillonite (3 g/100 g) and citric acid (5 and 10 g/100 g) were applied to the apples slices. All samples were packaged in polypropylene trays (14.6 cm * 11.4 cm * 6.5 cm) and stored at 5 +/- 2 degrees C and 85 +/- 3% RH for eight days. Every two days, the apples samples were evaluated for color, acidity, pH, soluble solids, water activity and polyphenol oxidase and peroxidase enzyme activity. The enzymatic browning of the apples slices was reduced for all films during storage. However, the films containing citric acid maintained the color characteristics, reducing the loss of quality associated the maintenance of acidity, soluble solids, water activity, reduction of polyphenol oxidase and peroxidase activity, thus prolonging the shelf life of the apples. PMID- 29580491 TI - Application of electrospray ionization mass spectrometry fingerprinting associated with macroscopic and histological analysis for Plantago major herbal infusions quality control. AB - The present study demonstrates the need to conduct an integrative quality control of teas marketed as Plantago major. In the present study, quality control checks were performed through macroscopic, microscopic and chemical analyses of commercial brands. Leaves with parts not allowed for consumption were found in all brands. Six brands showed histological similarity <50% with the authentic P. major. Eight brands demonstrated low chemical similarity (40 to 60%), indicating that they do not have the same compounds from the authentic P. major. All commercial samples are contaminated with aflatoxins, indicative of fungicide contamination and consequent degradation of phenolic compounds and reduction of antioxidant activity from the commercial samples. The difference in the present study is the integrative application of methods for success in the quality control of P. major, which can be applied to other species. Thus, more rigorous inspection actions in the production of teas to guarantee the therapeutic benefit of these products. PMID- 29580492 TI - Utilisation of water-in-oil-water (W1/O/W2) double emulsion in a set-type yogurt model for the delivery of probiotic Lactobacillus paracasei. AB - W1/O/W2 emulsion in set-type yogurt has the potential to segregate probiotics in order to avoid interference with the starter culture as well as protection against harsh processing and digestion conditions. Lactobacillus paracasei subsp. paracasei DC 412 probiotic cells in milk-based W1/O/W2 emulsions were incorporated in yogurt, in addition to starter cultures Lactobacillus bulgaricus and Streptococcus thermophilus, and the effect on the fermentation, bacterial growth kinetics, physicochemical properties, and structural characteristics was investigated. Stability of W1/O/W2 was monitored with optical microscopy and cryo SEM and localisation of encapsulated L. paracasei in yogurt was monitored using fluorescent microscopy. During fermentation, starter culture was not affected by introduction of L. paracasei and/or W1/O/W2 emulsion. The viability of L. paracasei encapsulated in W1/O/W2 emulsion was enhanced during storage and after exposure to simulated gastrointestinal conditions. L. paracasei remained within the inner W1 phase till the end of the storage period (28 days at 4 degrees C). Moreover, W1/O/W2 emulsion altered physicochemical and textural properties; however, these were within acceptable range. These results demonstrate the capability of W1/O/W2 emulsion to be utilised for probiotic fortification of yogurt to increase functionality without interfering with starter culture and fermentation. PMID- 29580493 TI - Development of LLDPE based active nanocomposite films with nanoclays impregnated with volatile compounds. AB - In this study, a novel procedure was performed for grafting of nanoclays (montmorillonite (MMT) and halloysite (HNT)) with essential oil constituents (thymol (THY), eugenol (EUG) and carvacrol (CRV)) using Tween 80 as surfactant and then the nanoclay particles were incorporated into LLDPE pellets (5 wt%) to produce active nanocomposite films using a twin screw extruder. The resulting nanocomposite films were analyzed for antimicrobial and antioxidant capacity as well as thickness, mechanical, color, barrier, thermal properties and surface morphology and molecular composition. Release of the active compounds from the films at the refrigerated and room temperature conditions were also tested. The results showed that the films had strong in vitro antibacterial activity against pathogenic bacteria (Salmonella Typhimurium, Escherichia coli O157:H7, Listeria monocytogenes, Staphylococcus aureus and Bacillus cereus) while their effect against lactic acid bacteria (Lactobacillus rhamnosus and Lb. casei) was limited. The lowest and highest DPPH scavenging ability levels were 65.59% and % 87.92, belonged to THY-MMT and EUG-MMT, respectively. Release of active compounds at 24 degrees C was much more rapid than at 4 degrees C. CRV-HNT and THY-HNT provided slower release than the other films. SEM results showed that nanoclays were uniformly dispersed in the polymer matrix with exceptional agglomerates. Incorporation of the active nanoclays significantly (P > 0.05) improved tensile strength and elongation of the films. The results confirmed that LLDPE based active nanocomposite films could be successfully produced due to its good interaction with MMT and HNT, activated with THY, EUG and CRV. PMID- 29580494 TI - Orange juice affects acylcarnitine metabolism in healthy volunteers as revealed by a mass-spectrometry based metabolomics approach. AB - Citrus juices, especially orange juice, constitute rich sources of bioactive compounds with a wide range of health-promoting activities. Data from epidemiological and in vitro studies suggest that orange juice (OJ) may have a positive impact on lipid metabolism. However, the effect of orange juice intake on blood lipid profile is still poorly understood. We have used two different blood samples, Dried Blood Spots (DBS) and plasma, to assess the effect of two week orange juice consumption in healthy volunteers by a mass-spectrometry based metabolomics approach. DBS were analysed by liquid chromatography mass spectrometry (LC-MS) and plasma samples were analysed by the gas chromatography mass spectrometry (GC-MS). One hundred sixty-nine lipids including acylcarnitines (AC), lysophosphatidylcholines (LysoPC), (diacyl- and acyl-alkyl-) phosphatidylcholines (PC aa and PC ae) and sphingomyelins (SM) were identified and quantified in DBS. Eighteen fatty acids were identified and quantified in plasma. Multivariate analysis allowed to identify an increase in C3:1, C5-DC(C6 OH), C5-M-DC, C5:1-DC, C8, C12-DC, lysoPC18:3, myristic acid, pentadecanoic acid, palmitoleic and palmitic acid and a decrease in nervonic acid, C0, C2, C10, C10:1, C16:1, C16-OH, C16:1-OH, C18-OH, PC aa C40:4, PC ae C38:4, PC ae C42:3, PC ae C42:4 and cholesterol levels after orange juice intake. A two-week period of orange juice intake could affect fatty acids beta-oxidation through mitochondrial and peroxisomal pathways, leading to an increase of short-chain acylcarnitines and a decrease of medium and long-chain acylcarnitines. This is the first report analyzing the effect of orange juice intake in healthy volunteers using a dried blood spot-based metabolomics approach.

AB - The aim of this study was to detect Cronobacter from 30 samples of ready-to-eat (RTE) salads and 30 foods from Japanese cuisine as commercially available in Brazil. The detection of Cronobacter was as according to the ISO standard 22964:2017. The isolates were phenotypically characterized by Vitek 2.0 and the antibiotic susceptibility profile was determined using the standardized agar disc diffusion method. Molecular characterization was accomplished by real-time PCR targeting dnaG gene, multiplex-PCR targeting cgcA gene, and fusA allele sequencing. Twenty-seven samples (45.0%) contained Cronobacter, 14 (23.3%) samples of foods from Japanese cuisine and 13 (21.7%) samples of RTE salads. Twenty-nine unique Cronobacter isolates were selected from the 27 positive samples and were identified as C. sakazakii (n = 18), C. malonaticus (n = 8), and C. dublinensis (n = 3). A high genetic diversity was observed, with 29 Cronobacter strains being assigned to 11 different fusA alleles, a ratio of 2.6 strains by fusA allele was found. The cgcA multiplex-PCR failed to identify many of the Cronobacter isolates at the species level. Four (13.8%) Cronobacter isolates were resistant to one or more antibiotics tested (n = 12). The presence of Cronobacter in RTE foods could be a potential threat to human health and highlights the need for high levels of hygiene, particularly when preparing food for elderly, immunosuppressed persons or adults with prior underlying pathology. Epidemiological surveillance agencies should be aware of the risk that these RTE foods may represent, for these groups.

AB - An accurate method to heat treat flour samples has been used to quantify the effects of heat treatment on flour functionality. A variety of analytical methods has been used such as oscillatory rheology, rheomixer, solvent retention capacity tests, and Rapid Visco Analysis (RVA) in water and in aqueous solutions of sucrose, lactic acid, and sodium carbonate. This work supports the hypothesis that heat treatment facilitates the swelling of starch granules at elevated temperature. Results furthermore indicated improved swelling ability and increased interactions of flour polymers (in particular arabinoxylans) of heat treated flour at ambient conditions. The significant denaturation of the proteins was indicated by a lack of gluten network formation after severe heat treatments as shown by rheomixer traces. Results of these analyses were used to develop a possible cake flour specification. A method was developed using response surfaces of heat treated flour samples in the RVA using i) water and ii) 50% sucrose solution. This can uniquely characterise the heat treatment a flour sample has received and to establish a cake flour specification. This approach might be useful for the characterisation of processed samples, rather than by baking cakes. Hence, it may no longer be needed to bake a cake after flour heat treatment to assess the suitability of the flour for high ratio cake production, but 2 types of RVA tests suffice.

Therefore, sugar reduction in these products could contribute to the prevention of various negative health conditions, such as obesity, diabetes and cardiovascular diseases. In this context, the present work aimed to study consumer sensory and hedonic perception towards sugar reduction in fruit nectars. Five sequential difference thresholds for added sugar in three fruit nectars (passion fruit, orange/passion fruit and orange/pomegranate) were determined based on consumer perception. In each test, difference thresholds were estimated using survival analysis based on the responses of 50 consumers to six paired comparison tests. Each pair was composed of two samples, a control nectar and a sample that was reduced in added sugar from the control. Consumers were asked to try each of the samples in each pair and to indicate which was sweeter. Then, consumers' sensory and hedonic perception of nectar samples was evaluated for each nectar using a 9-point hedonic scale and a check-all-that-apply question. Difference thresholds were estimated in 4.20%-8.14% of the added sugar concentration of the nectars. No significant differences in overall liking were detected for fruit nectars with 20% sugar reduction. However, large heterogeneity in consumer hedonic reaction towards sugar reduction was found, which should be taken into account in the design of sugar reduction programs. Consumer hedonic reaction towards sugar reduction was product dependent. Results from the present work reinforce the idea that gradual sugar reduction in sugar sweetened beverages is a feasible strategy that could contribute to reduce the sugar intake of the population.

AB - The oxidative stability, as well as the chemical composition of Amygdalus reuteri kernel oil (ARKO), were evaluated and compared to those of Amygdalus scoparia kernel oil (ASKO) and extra virgin olive oil (EVOO) during and after holding in the oven (170 degrees C for 8 h). The oxidative stability analysis was carried out by measuring the changes in conjugated dienes, carbonyl and acid values as well as oil/oxidative stability index and their correlation with the antioxidant compounds (tocopherol, polyphenols, and sterol compounds). The oleic acid was determined as the predominant fatty acid of ARKO (65.5%). Calculated oxidizability value and an iodine value of ARKO, ASKO and EVOO were reported as 3.29 and 3.24, 2.00 and 100.0, 101.4 and 81.9, respectively. Due to the high wax content (4.5% and 3.3%, respectively), the saponification number of ARKO and ASKO (96.4 and 99.8, respectively) was lower than that of EVOO (169.7). ARKO had the highest oxidative stability, followed by ASKO and EVOO. Therefore, ARKO can be introduced as a new source of edible oil with high oxidative stability.

AB - Biofilms are communities of bacterial cells that serve to protect them from external adverse influences and enhance bacterial resistance to antibiotics and sanitizers. Here, we studied the regulatory effects of glucose and sodium chloride on biofilm formation in Salmonella serovar Dublin (S. Dublin). To analyze expression levels of the quorum sensing gene luxS, we created a luxS knockout mutant. Also, antimicrobial resistance, hydrophobicity and autoinducer-2 (AI-2) activity of both the wild-type (WT) and the mutant strain were investigated. Our results revealed that glucose was not essential for S. Dublin biofilm formation but had an inhibitory effect on biofilm formation when the concentration was over 0.1%. NaCl was found to be indispensable in forming biofilm, and it also exerted an inhibitory effect at high concentrations (>1.0%). Both the WT and the mutant strains displayed significant MIC growth after biofilm formation. An increase of up to 32,768 times in the resistance of S. Dublin in biofilm phonotype against antibiotic (ampicillin) compared to its planktonic phonotype was observed. However, S. Dublin luxS knockout mutant only showed slight differences compared to the WT strain in the antimicrobial tests although it displayed better biofilm-forming capacity than the WT strain. The mutant strain also exhibited higher hydrophobicity than the WT strain, which was a feature related to biofilm formation. The production of the quorum sensing autoinducer-2 (AI-2) was significantly lower in the mutant strain than in the WT strain since the LuxS enzyme, encoded by the luxS gene, plays an essential role in AI-2 synthesis. However, the limited biofilm-forming ability in the WT strain indicated AI-2 was not directly related to S. Dublin biofilm formation. Furthermore, gene expression analysis of the WT and mutant strains revealed upregulation of genes related to biofilm stress response and enhanced resistance in the luxS mutant strain, which may provide evidence for the regulatory role of the luxS gene in biofilm formation. PMID- 29580500 TI - Effect of preheat treatment of milk proteins on their interactions with cyanidin 3-O-glucoside. AB - In this study, the binding of cyanidin-3-O-glucoside (C3G) to preheated milk proteins beta-lactoglobulin (beta-Lg) and beta-casein (beta-CN) at 55-90 degrees C under pH 3.6 and pH 6.3 was investigated using multi-spectral techniques. Fluorescence quenching spectroscopy data showed C3G quenched milk proteins' fluorescence strongly. Thermodynamic analysis revealed that C3G bound to beta-Lg mainly through hydrogen bonding and hydrophobic interactions, and that their binding affinity increased gradually with increasing preheating temperature at pH 6.3, whereas it decreased at pH 3.6. Hydrogen bonding and van der Waals forces played the major roles in the interaction of beta-CN with C3G, their affinity decreasing with increasing preheating temperature at both pH values. The combination of C3G and preheated beta-Lg at 85 degrees C had the strongest binding affinity, with a KA of 14.10 (+/-0.33) * 105 M-1 (pH 6.3, 298 K). Preheating of milk proteins did not change their major forces with C3G. Fourier transform infrared spectra (FT-IR) results showed that C3G binding altered the secondary structures of beta-Lg and beta-CN by reducing the proportion of alpha helix and beta-sheet structures and increasing the proportion of random coil and turn structures. The structural changes of preheated beta-Lg upon C3G binding were more pronounced than that of native beta-Lg, while there was little difference between preheated and native beta-CN in their structural changes upon C3G binding. These results will be helpful in better understanding the relevance of native and preheated milk protein-C3G interactions to the stability of C3G, and in promoting its application in the food industry as a natural pigment. PMID- 29580501 TI - Extraction and identification of antimicrobial peptides from the Canastra artisanal minas cheese. AB - Canastra artisanal Minas cheese samples were collected in Minas Gerais - Brazil. The samples were evaluated in order to observe the presence of antimicrobial peptides during 30 days of ripening. Soluble peptides extracted from the cheeses were fractionated by reverse phase liquid chromatography and their fractions evaluated for inhibitory action of E. coli. Fractions containing antimicrobial activity were analyzed by MALDI-TOF/TOF and then peptides were sequenced and identified using MASCOT Daemon coupled with UniProt database. The identified peptides were then validated by SCAFFOLD application. The peptides present in fractions with antimicrobial activity were RPKHPIKHQ, RPKHPIKHQG, RPKHPIKHQGLPQ and RPKHPIKHQGLPQE, HQPHQPLPPT and MHQPHQPLPPT. Peptide sequences PKHPIKHQ, RPKHPIKHQG, RPKHPIKHQGLPQ and RPKHPIKHQGLPQE were originated from alphas1-casein and are their fragments belonging to Isracidine, which in turn is a well known antimicrobial peptide. The HQPHQPLPPT and MHQPHQPLPPT peptides were related to beta-casein and were isolated in other studies, but their biological activities are still unknown. PMID- 29580502 TI - Food grade microemulsion systems: Sunflower oil/castor oil derivative ethanol/water. Rheological and physicochemical analysis. AB - Microemulsions are thermodynamically stable systems that have attracted considerable attention in the food industry as delivery systems for many hydrophobic nutrients. These spontaneous systems are highly dependent on ingredients and composition. In this work phase diagrams were constructed using two surfactants (Kolliphor RH40 and ELP), water, sunflower oil, and ethanol as cosurfactant, evaluating their physicochemical properties. Stability of the systems was studied at 25 and 60 degrees C, monitoring turbidity at 550 nm for over a month to identify the microemulsion region. Conductivity was measured to classify between water-in-oil and oil-in-water microemulsions. The phase diagram constructed with Kolliphor RH40 exhibited a larger microemulsion area than that formulated with Kolliphor ELP. All formulations showed a monomodal droplet size distribution with low polydispersity index (<0.30) and a mean droplet size below 20 nm. Systems with higher water content presented a Newtonian behavior; increasing the dispersed phase content produced a weak gel-like structure with pseudoplastic behavior under flow conditions that was satisfactorily modeled to obtain structural parameters. PMID- 29580503 TI - Encapsulation of purple corn and blueberry extracts in alginate-pectin hydrogel particles: Impact of processing and storage parameters on encapsulation efficiency. AB - Purple corn (PC) and blueberry (BB) extracts were encapsulated in alginate-pectin hydrogel particles to protect anthocyanins (ACNs) from degradation. Combinations of alginate to pectin ratios at 82 to 18% and 43 to 57% and total gum concentrations (TGC) at 2.2% and 2.8% TGC were prepared to encapsulate both PC and BB ACN. The alginate-pectin hydrogel particles containing PC or BB extracts were produced by dripping solution into pH 1.2 buffer. Blueberry extract encapsulation efficiency was significantly higher than that of purple corn extract due to ACN chemical structure differences and the compatibility between the ACN structures and alginate-pectin hydrogel structure at the low pH environment. Effect of initial ACN concentration in droplets, particle shape, alginate to pectin ratio, TGC, ACN source, and curing bath conditions on encapsulation efficiency after curing (EEm) was investigated. The initial ACN concentration and particle shape didn't influence the EEm, while the alginate to pectin ratio, TGC, ACN source and the pH of the curing bath showed significant effect on the EEm. The EEm was improved from 26% to 65% for PC ACN and from 48% to 116% for BB ACN by augmenting curing bath with ACN at various concentrations. The ACN retention during storage (ARs) in hydrogel particles stored in pH 3.0 buffer was improved at low temperature and high particle weight to solution volume ratio. Higher amount of ACN was retained in the hydrogel particles when spherical particles were used. Encapsulation in hydrogel particles significantly reduced the anthocyanin photodegradation upon exposure to fluorescence light. The degradation of ACN was described with a first-order kinetics with half-life values of 630 h for encapsulated PC ACN and 58 h for PC ACN aqueous solution. Hydrogel production and subsequent storage conditions can be optimized to increase the anthocyanin delivered to human body using the low pH beverages such as fruit juices as a delivery vehicle. PMID- 29580504 TI - In vitro digestion models suitable for foods: Opportunities for new fields of application and challenges. AB - In vitro digestion assays simulate the physiological conditions of digestion in vivo and are useful tools for studying and understanding changes, interactions, as well as the bioaccessibility of nutrients, drugs and non-nutritive compounds. The technique is widely used in fields such as nutrition, pharmacology and food chemistry. Over the last 40 years, more than 2500 research articles have been published using in vitro digestion assays (85% of which have been published in the last two decades) to elucidate multiple aspects such as protein digestibility, nutrient interactions or the viability of encapsulated microorganisms. The most recent trend in the use of this technique involves the determination of the antioxidant activity of bioactive compounds after digestion. However, the inability to reproduce certain in vivo digestion events, as well as the multiple models of in vitro digestion, point to a need to optimize and validate the method with in vivo assays to determine its limitations and uses. The purpose of this paper is to provide an overview of the current state of the art of in vitro digestion models through an analysis of how they have evolved in terms of the development of digestion models (parameters, protocols, guidance) and taking into consideration the boom in new fields of application. PMID- 29580505 TI - The prevalence of Listeria spp. food contamination in Iran: A systematic review and meta-analysis. AB - Listeria monocytogenes can cause circling disease, encephalitis, meningitis, septicemia, and mastitis in dairy cattle. Contamination from the environment can contaminate foods with Listeria spp. Consumption of foods containing L. monocytogenes can lead to listeriosis in susceptible people (adults with a compromised immune system), pregnant women, and infants. The objective of this study was to determine the prevalence of Listeria spp. and L. monocytogenes in various foods in Iran. We searched PubMed, Science direct, Scopus, Google scholar, and Iranian local databases including Iranian scientific information database and Magiran for relevant studies up to May 2015 using related keywords. In our preliminary search, we retrieved 1344 articles. After removing duplicates and reviewing titles/abstracts, 117 articles were considered, out of which, 75 articles had sufficient quality for inclusion in this meta-analysis. The prevalence of Listeria spp. contamination was about 18.3% in poultry, 8.5% in raw meat, 14.6% in ready-to-eat (RTE) foods, 10% in sea foods, 7.3% in traditional dairy, 3.2% in commercial dairy, and 0.1% in eggs. The findings showed that L. monocytogenes was most prevalent in ready to eat (9.2%), seafood (5.1%), poultry (5%), traditional dairy (4%), raw meat (2.6%), commercial dairy (1.4%), and egg (0.2%), respectively. Furthermore, the presence of L. monocytogenes particularly in RTE foods (that are consumed without further heat processing) and under-cooked products could be a potential risk for public health. So, contamination should be controlled at all levels of the food chain. PMID- 29580506 TI - Inoculation of Torulaspora delbrueckii as a bio-protection agent in winemaking. AB - In oenology, bio-protection consists in adding bacteria, yeasts or a mixture of microorganisms on grape must before fermentation in order to reduce the use of chemical compounds such as sulphites. More particularly, non-Saccharomyces yeasts are used as a total or partial alternative to sulphites. However, scientific data capable of proving the effectiveness of adding these yeasts on grape must is lacking. This study reports the analysis of antimicrobial and antioxidant effects of one non-Saccharomyces yeast, Torulaspora delbrueckii, inoculated at the beginning of the white winemaking process in two Burgundian wineries as an alternative to sulphiting. The implantation of the T. delbrueckii strain was successful in both wineries and had no impact on fermentation kinetics. Adding T. delbrueckii reduced biodiversity during the pre-fermentation stages compared to sulphited controls and it also effectively limited the development of spoilage microorganisms in the same way as the addition of sulphites. T. delbrueckii could protect must and wine from oxidation as demonstrated by the analysis of colour and phenolic compounds. This is the first evidence that early addition of T. delbrueckii during winemaking can be a microbiogical and chemical alternative to sulphites. However, its contribution seems to be matrix dependent. PMID- 29580507 TI - Study of two-stage ohmic hydro-extraction of essential oil from Artemisia aucheri Boiss.: Antioxidant and antimicrobial characteristics. AB - The effect of two-stage ohmic-assisted hydrodistillation (TSOH) on the extraction and characteristics of essential oils (EOs) from the Artemisia aucheri Boiss. was studied, and the results were compared to conventional hydrodistillation (HD). According to the results, the yield of EOs obtained through TSOH was almost 30% higher than those extracted by HD in nearly one-quarter of a time used by the HD. Scanning electron micrographs of A. aucheri leaves showed almost complete eruption of EO glands and their surrounding area in TSOH extraction method, hence achieving higher yield. The components of the EOs obtained through TSOH were only slightly different from those of HD. GC/MS analysis indicated some differences in the quantity of the main components, too. The main components of EOs were identified as Thymol, Linalool, Geraniol, Camphor, and 1, 8-Cineole, Davana ether and Cis-Davanone. Thymol (~17%) and Cis-Davanone (~23%) were the highest quantity in the EOs extracted from TSOH and HD, respectively. The variation of antioxidant and antimicrobial activities of the EOs may be attributed to these differences in the percentage of the main components. The radical scavenging activity of the EOs obtained by TSOH was almost twice that of HD. Based on antimicrobial activity assays, the EOs were efficient against S. aureus (a Gram-positive), E. coli (a Gram-negative), and S. cerevisiae (yeast). However, the efficacy was higher in gram-positive than gram-negative bacteria and yeast. The results indicate TSOH has a potential to produce EOs from herbal plants at a faster rate, higher yield, being probably more efficient in terms of energy although having similar antimicrobial and antioxidant efficacy.

AB - Fat separation, gelation or sedimentation of UHT milk during shelf-storage represent instability phenomena causing the product rejection by consumers. Stability of UHT milk is of increasing concern because access to emerging markets currently implies for this product to be stable during shipping and prolonged storage, up to 12 months. The role of microfiltration prior to UHT process in avoiding or retarding the gelation or sediment formation was studied by comparing microfiltered UHT milk to conventional UHT milk. A second trial was set up to study the effects of double ultra-high pressure homogenization in delaying the cream rising and UHT milk homogenized once at lower pressure was taken as control. All milk samples were produced at industrial plant level. Milk packages were stored at 22 degrees C, opened monthly for visually inspecting the presence of cream layer, gel or sediment and then analysed. Microfiltration markedly delayed the formation of both gel particles and sediment, with respect to the control, and slowed down the proteolysis in terms of accumulation of peptides although no correlation was observed between the two phenomena. The double homogenization, also evaluated at ultra-structural level, narrowed the fat globule distribution and the second one (400 MPa), performed downstream to the sterilization step, disrupted the fat-protein aggregates produced in the first one (250 MPa). The adopted conditions avoided the appearance of the cream layer in the UHT milk up to 18 months. This study contributes important knowledge for developing strategies to delay instability phenomena in UHT milk destined to extremely long shelf storage.

AB - Biodegradable polymers with antibacterial properties are highly desirable materials for active food packaging applications. Thymol, a dietary monoterpene phenol with a strong antibacterial activity is abundant in plants belonging to the genus Thymus. This study presents two approaches for supercritical CO2 impregnation of poly(lactic acid)(PLA)/poly(epsilon-caprolactone)(PCL) blended films to induce antibacterial properties of the material: (i) a batch impregnation process for loading pure thymol, and (ii) an integrated supercritical extraction-impregnation process for isolation of thyme extract and its incorporation into the films, operated in both batch or semi-continuous modes with supercritical solution circulation. The PCL content in films, impregnation time and CO2 flow regime were varied to maximize loading of the films with thymol or thyme extract with preserving films' structure and thermal stability. Representative film samples impregnated with thymol and thyme extract were tested against Gram (-) (Escherichia coli) and Gram(+) (Bacillus subtilis) model strains, by measuring their metabolic activity and re-cultivation after exposure to the films. The film containing thymol (35.8 wt%) showed a strong antibacterial activity leading to a total reduction of bacterial cell viability. Proposed processes enable fast, controlled and organic solvent-free fabrication of the PLA/PCL films containing natural antibacterial substances at moderately low temperature, with a compact structure and a good thermal stability, for potential use as active food packaging materials. PMID- 29580512 TI - Synergistic effect of X-ray irradiation and sodium hypochlorite against Salmonella enterica serovar Typhimurium biofilms on quail eggshells. AB - The present study investigated the synergistic bactericidal effects of combined X ray irradiation (0.5, 1.0, 1.5, and 2.0 kGy) and sodium hypochlorite (NaOCl) (50, 100, 150, 200, and 300 ppm) treatment on the reduction of S. enterica serovar Typhimurium ATCC 14028 biofilms on quail eggshells. Additionally, the color change of the quail eggshells was measured by hunter color "L" (lightness), "a" (red/green), "b" (yellow/blue), and "DeltaE" (total color difference). Additionally, the puncture force was tested to evaluate eggshell thickness after the combined treatments. The highest biofilm reduction values were observed as 4.6 log CFU/egg after X-ray (2.0 kGy) and NaOCl (300 ppm) treatment. Moreover, the synergistic reduction in values after combined treatment was evaluated, and the highest biofilm reduction value was 4.3 log CFU/egg by 2.0 kGy X-ray/50 ppm NaOCl (1.47 log higher than the sum of reduction values of the individual treatments). The color of the quail eggshell and puncture force were not significantly changed by combined treatments (p > 0.05 at both cases). Consequently, 2.0 kGy X-ray/50 ppm NaOCl was considered optimal for combination treatment for eliminating S. enterica ser. Typhimurium biofilms on eggshell without any color or thickness changes. Furthermore, combination treatment could be useful for improving microbiological safety in the quail egg industry. PMID- 29580513 TI - Food isolate Listeria monocytogenes harboring tetM gene plasmid-mediated exchangeable to Enterococcus faecalis on the surface of processed cheese. AB - The genetic basis of tetracycline resistance in a food isolate Listeria monocytogenes (Lm16) was evaluated. Resistance to tetracycline was associated with the presence of the tetM gene in plasmid DNA. The sequence of tetM showed 100% of similarity with the Enterococcus faecalis sequences found in the EMBL database, suggesting that Lm16 received this gene from E. faecalis. Various size bands were detected in the DNA plasmid analysis, the largest being approximately 54.38 kb. Transferability of the tetM gene was achieved in vitro by agar matings between Lm16 and E. faecalis JH2-2, proving the potential for the spread of tetM by horizontal gene transfer. Furthermore, the conjugation experiments were performed on the surface of processed cheese, confirming the transferability in a food matrix. PCR assays were used to confirm the identity of E. faecalis and to detect the tetM gene in transconjugant bacteria. Additionally, the minimal inhibitory concentration for tetracycline and rifampicin and plasmid profiling were performed. This is the first report of a food isolate L. monocytogenes carrying the tetM gene in plasmid DNA, and it highlights the potential risk of spreading antimicrobial resistance genes between different bacteria. PMID- 29580514 TI - Addition of sucrose during the blueberry heating process is good or bad? Evaluating the changes of anthocyanins/anthocyanidins and the anticancer ability in HepG-2 cells. AB - The objectives of this study were to evaluate the role of sucrose on the stability of anthocyanins during heating and the anticancer effects of anthocyanins/anthocyanidins on HepG-2 cells. The anthocyanins extract was heated at 70 degrees C, 100 degrees C, and 120 degrees C in the presence of 5%, 10%, and 20% sucrose. Total anthocyanin content, anthocyanin/anthocyanidin species, and the ability to induce HepG-2 cell apoptosis were evaluated. The results indicated that the total anthocyanin content decreased during heating at temperatures above 70 degrees C. Anthocyanins were degraded into anthocyanidins after heat treatment and the degradation rate positively correlated with temperature. The degradation of anthocyanins was inhibited with the addition 5% to 20% sucrose. However, sucrose had no protective effect on the total anthocyanin content. The anticancer ability of blueberry extract was assayed using HepG-2 cells and found to be associated with the concentration of anthocyanins. Anthocyanins displayed stronger anticancer activity than anthocyanidins and this has not been reported so far. PMID- 29580515 TI - Probiotic potential of yeasts isolated from pineapple and their use in the elaboration of potentially functional fermented beverages. AB - Pineapple (Ananas comosus (L.) Merril) is a tropical fruit rich in nutrients characterized by a pleasant taste and widely consumed in several countries. It is used to produce juice, jams and wine. In this work, 150 yeasts isolates were obtained from peel (18) and spontaneously fermented pineapple pulp (132). The probiotic potential of 50 isolates was studied. Survival at pH 2.0, pepsin 3.0 g/L, and tolerance of bile salts (0.1 and 1% (w/v) were determined as indicators of survival potential of the isolates during the passage through the human gastrointestinal tract in simulated conditions. The selected isolates were also evaluated for their resistance to 6 antibiotics, antimicrobial activity against 6 pathogenic bacteria and autoaggregation and hydrophobicity properties. Five of them survived to gastrointestinal conditions, showed antibiotic resistance and autoaggregation properties. They were identified by MALDI-TOF MS and sequencing of ITS region as Candida lusitaniae (3) and Meyerozyma caribbica (2). Among these isolates, M. caribbica 9 D was evaluated in the production of a fermented pineapple beverage. The Saccharomyces cerevisiae var. boulardii was used as control, due to the fact that it is the only commercially available probiotic yeast. With M. caribbica inoculum, the beverage produced showed higher concentrations of residual glucose (24.19 g/L) and fructose (8.67 g/L), lower concentration of acetic acid (0.22 g/L); higher total phenolic compounds (196.93 mg/L), catechin (155.56 mg/L), chlorogenic acid (3.64 mg/L), vanillin (0.18 mg/L) and ferulic acid (33.2 mg/L). It was observed that M. caribbica population remained stable during refrigerated storage with cell counts greater than 7.00 log CFU/mL over 21 days. Compared to beverage produced with S. cerevisiae var. boulardii, the one produced with M. caribbica presented greater acceptance in the sensorial analysis for taste, aroma and general acceptance. The fermented pineapple beverage prepared with M. caribbica proved to be a good alternative in development of a potential probiotic beverage with different sensory and nutritional properties. PMID- 29580516 TI - Effect of cellulose nanocrystals from sugarcane bagasse on whey protein isolate based films. AB - Whey protein isolate (WPI) has been utilized as edible film or food packaging material. However, WPI films are hydrophilic due to highly polar amino acids which provide a moderate barrier to water vapor and low mechanical properties. To overcome these drawbacks, cellulose nanocrystals (CNCs) extracted from sugarcane bagasse were incorporated with whey protein. FTIR and TGA were used to confirm the changes in chemical structures and to observe the thermal properties, respectively. The CNCs had sizes of 200-300 nm and diameters of 20-40 nm using TEM and AFM technique, respectively. Different amounts of CNCs (0-8 wt% based on WPI) were added into whey protein solution and formed films. The lightness and transparency of the films tended to decrease with increasing WPI content. The water activity (aw) and water solubility of those films increased, whereas their water contact angle values decreased, implying that the film became more hydrophilic when the cellulose nanocrystal was added. The addition of CNCs increased the tensile strength and Young's modulus and reduced the water vapor permeability of WPI-based CNC films. However, the CNCs did not change the oxygen permeability of the film. Therefore, the obtained WPI films provided good mechanical performance and may be promising as an alternative product for film packaging. PMID- 29580517 TI - Qualitative carbonyl profile in coffee beans through GDME-HPLC-DAD-MS/MS for coffee preliminary characterization. AB - In this work, an analytical methodology for volatile carbonyl compounds characterization in green and roasted coffee beans was developed. The methodology relied on a recent and simple sample preparation technique, gas diffusion microextraction for extraction of the samples' volatiles, followed HPLC-DAD-MS/MS analysis. The experimental conditions in terms of extraction temperature and extraction time were studied. A profile for carbonyl compounds was obtained for both arabica and robusta coffee species (green and roasted samples). Twenty-seven carbonyl compounds were identified and further discussed, in light of reported literature, with different coffee characteristics: coffee ageing, organoleptic impact, presence of defective beans, authenticity, human's health implication, post-harvest coffee processing and roasting. The applied methodology showed to be a powerful analytical tool to be used for coffee characterization as it measures marker compounds of different coffee characteristics. PMID- 29580518 TI - A different approach for the analysis of grapes: Using the skin as sensing element. AB - In this work, an alternative method to monitor the phenolic maturity of grapes was developed. In this approach, the skins of grapes were used to cover the surface of carbon paste electrodes and the voltammetric signals obtained with the skin-modified sensors were used to obtain information about the phenolic content of the skins. These sensors could easily detect differences in the phenolic composition of different Spanish varieties of grapes (Mencia, Prieto Picudo and Juan Garcia). Moreover, sensors were able to monitor changes in the phenolic content throughout the ripening process from veraison until harvest. Using PLS-1 (Partial Least Squares), correlations were established between the voltammetric signals registered with the skin-modified sensors and the phenolic content measured by classical methods (Glories or Total Polyphenol Index). PLS-1 models provided additional information about Brix degree, density or sugar content, which usually used to establish the harvesting date. The quality of the correlations was influenced by the maturation process and the structural and mechanical skin properties. Thus the skin sensors fabricated with Juan Garcia and Prieto Picudo grapes (that showed faster polyphenolic maturation and a higher amount of extractable polyphenols than Mencia), showed good correlations and therefore could be used to monitor the ripening.

The rye flours used differed in their particle size. R1 and R2 resulted from jet milling of the R flour at two different feed rates. The mean particle size of W, R, R1 and R2 flours was 173.87, 100.91, 54.59 and 35.66 MUm, respectively. Glycerol was used as plasticizer at concentrations of 0.5, 0.7 and 1 g/g of flour. Films made from mixtures of flours (50:50 w/w) were also studied in the presence of 0.7 g glycerol/g of flour. Colour, moisture content, solubility, thickness, viscosity, microstructure and mechanical properties were assessed. In most cases the films were homogeneous. Film moisture content, thickness, opacity and mechanical properties were correlated to glycerol concentration. Particle size was found important for the mechanical properties. Wheat films were lighter ([L*] ~ 49) and less opaque (135). For both single and composite films, moisture content varied from 24 to 35%, solubility from 43.5-58%, opacity from 135 to 371, thickness from 0.66-0.72 mm and mechanical strength from 0.68-1.7 MPa. All film-forming solutions exhibited shear thinning behaviour. Wheat flour dominated most of the studied properties in composite films. Rye films were more opaque, with relatively high solubility but greater mechanical strength.

AB - Defective textures in dry-cured ham are a common problem that causes important economic losses in the ham industry. An increase of proteolysis during the dry cured ham processing may lead to high adhesiveness and consumer rejection of the product. Therefore, the influence of proteolysis index (PI) on instrumental adhesiveness, free amino acids and volatile profile of dry-cured ham was assessed. Two hundred Spanish dry-cured ham units were firstly classified according to their PI: low PI (<32%), medium PI (32-36%) and high PI (>36%). Instrumental adhesiveness was affected by PI, showing the lowest values in the batch with low PI. Significant differences (P < 0.05) among groups were found in six amino acids: serine, taurine, cysteine, methionine, isoleucine and leucine. The content of leucine, serine, methionine, and isoleucine significantly (P < 0.05) increased as the proteolysis index rose. However, taurine and cysteine content showed an opposite behaviour, reaching the highest values in the dry cured hams with low PI. Significant differences (P < 0.001) in the total content of volatile compounds among ham groups were observed, with the highest concentration in the batch with low PI, and decreasing the concentration as the PI increased. Regarding the different chemical families of volatiles, the hydrocarbons (the main family), alcohols, aldehydes, ketones and acids were more abundant in the hams showing the lowest PI. Esters did not show significant differences among the three batches of hams studied. The present study demonstrated that, apart from the effect on the adhesiveness, an excessive proteolysis seems to be associated with negative effects on the taste and aroma of the dry-cured ham. PMID- 29580521 TI - Yellow tea (Camellia sinensis L.), a promising Chinese tea: Processing, chemical constituents and health benefits. AB - Yellow tea, also known as huangcha in Chinese, is a lightly fermented tea unique to China. As a rare and precious variety of tea, it has gained increasing popularity in recent years because of its pleasant mellow taste and known health benefits such as anti-oxidation, anti-inflammation and anti-cancer properties. Yellow tea is similar to green tea in many ways. The initial production process of both teas is the same, but the production of yellow tea requires additional steps. A unique procedure called "sealed yellowing" is always involved in yellow tea processing to increase the oxidation level and remove the characteristic grassy smell associated with green tea while still preserving its health benefits. Compared to other types of teas, yellow tea is much less well-known and studied. In this review, the history and classification of yellow tea are introduced. The processing procedures, including detailed information about "sealed yellowing", are presented. The bioactive chemical compounds common in various types of teas or unique to yellow tea are discussed. Finally, future needs in research and development of yellow tea are proposed. PMID- 29580522 TI - Citrus fruit extracts with carvacrol and thymol eliminated 7-log acid-adapted Escherichia coli O157:H7, Salmonella typhimurium, and Listeria monocytogenes: A potential of effective natural antibacterial agents. AB - Despite the widespread belief that citrus fruit extracts (CFEs) are microbiologically safe due to their acidity, limited bactericidal effect results in low applicability as antibacterial agent and outbreaks occurred by acid adapted pathogens. Here, we examined the antibacterial effects of CFEs [lime (Citrus medica), lemon (Citrus limon), calamansi (Citrus microcarpa)] combined with essential oil components (EOCs; carvacrol and thymol) against non-acid adapted/acid-adapted Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes under 22 degrees C for 5 min. CFEs (<20%) alone or small amounts of EOCs (2.0 mM; 0.032%) alone could not inactivate the target bacteria effectively. However, combined treatments exhibited marked synergy: CFE + EOCs eliminated all the bacteria (>6.9 log CFU/ml). Among the CFEs tested, the highest synergism was shown by calamansi, an exotic citrus fruit previously unrecognized as an antibacterial agent. Although acid-adaptation improved bacterial survival, calamansi (<20%) + EOCs (<0.032%) completely inactivated even the most resistant pathogen (E. coli O157:H7). Validation test also showed that all tested commercial juice products also eliminated acid-adapted pathogens when used with EOCs. Physicochemical analysis of tested CFEs (pH measurement and HPLC analysis of components) revealed that low pH and flavanone (hesperidin) did not contribute to the synergistic bactericidal effects. Rather, the high citric acid content is likely to contribute to the strong synergistic effect with EOCs by damaging susceptible bacterial membranes. Sensory scores for CFEs were not altered by addition of EOCs at concentrations up to 1.5 mM. This study provides new insight into the utility of CFEs with EOCs to improve not only the microbiological safety of food products containing CFEs but also their applicability as natural antibacterial complex. PMID- 29580523 TI - Postprandial lipemia and fecal fat excretion in rats is affected by the calcium content and type of milk fat present in Cheddar-type cheeses. AB - The aim of this study was to better understand the effect of calcium on the bioavailability of milk lipids from a cheese matrix using a rat model. Cheddar type cheeses were manufactured with one of three types of anhydrous milk fat, control, olein or stearin, and salted with or without CaCl2. The cheeses were fed to rats and postprandial lipemia was monitored. Feces were analyzed to quantify fatty acids excreted as calcium soaps. Higher calcium concentration in cheese caused a higher and faster triacylglycerol peak in blood, except for cheeses containing stearin. Furthermore, calcium soaps were more abundant in feces when the ingested cheese had been enriched with calcium and when the cheese was prepared with stearin. Increased lipid excretion was attributable to the affinity of saturated long-chain fatty acids for calcium. Results showed that lipid bioaccessibility can be regulated by calcium present in Cheddar cheese. This study highlights the nutritional interaction between calcium and lipids present in the dairy matrix and confirms its physiological repercussions on fatty acid bioavailability. PMID- 29580524 TI - Investigation on complex coacervation between fish skin gelatin from cold-water fish and gum arabic: Phase behavior, thermodynamic, and structural properties. AB - The study is aimed to investigate phase behavior, thermodynamic, and structural properties based on complex coacervation between fish skin gelatin (FSG) from cold-water fish and gum arabic (GA). Phase separation behavior between FSG and GA was investigated as a function of pH through varying mixing ratios from 4:1 to 1:4 at 25 degrees C and 1.0 wt% of total biopolymer concentration. The turbidity of FSG-GA mixture reached the maximum (1.743) at the 1:2 of mixing ratio and pHopt 3.5, and stabilized at zero. Then physicochemical properties of FSG-GA coacervates at pHopt 3.5 and FSG-GA mixtures at pH 6.0 (>pHc) were evaluated. Scanning electron microscope (SEM) and X-ray diffraction (XRD) showed that the interactions between FSG and GA occurred at pHopt 3.5 and were very weak at pH 6.0 (>pHc). The isothermal titration calorimetry (ITC) results including the negative Gibbs free energy change (DeltaG = -18.71 +/- 1.300 kJ/mol), binding enthalpy (DeltaH = -41.81 +/- 1.300 kJ/mol) and binding entropy (TDeltaS = -23.10 kJ/mol) indicated that the complexation between FSG and GA was spontaneous and driven by negative enthalpy owing to the electrostatic interaction and hydrogen bondings. The zeta potential (ZP) of FSG-GA coacervates at pHopt 3.5 was -9.00 +/ 0.79 mV that was not close to electrically neutral, indicating other interactions besides electronic interaction. Hydrogen bondings in FSG-GA mixtures at pH 6.0 and 3.5 were found to be stronger than pure FSG at pH 6.0 and 3.5 owing to that the amide II peaks shifted to high wavenumbers. Electronic interaction was proven to exist in FSG-GA mixtures at pH 6.0 through the vanishment of asymmetric COO- stretching. However, the electronic interaction in FSG-GA coacervates at pHopt 3.5 was obviously stronger than FSG-GA mixtures at pH 6.0, resulting from the vanishment of asymmetric and symmetric COO- stretching vibration and the positively charged FSG and GA. The intrinsic fluorescence represented that the introduction of GA changed the microenvironment of tyrosine residues in FSG, which may be owing to the unfolding of the tertiary conformation. Moreover, the decrease of pH could promote the formation of random coils of FSG through circular dichroism (CD). Therefore the addition of GA into FSG and decrease of pH might enhance the conformation freedom of FSG, which would bring about favorable entropic effects and contribute to the complexation. PMID- 29580525 TI - Assessment of effects of phenolic fractions from leaves and petals of dandelion in selected components of hemostasis. AB - Aerial parts and roots of Taraxacum officinale (dandelion) have been found to be rich sources of polyphenols, including cinnamic acid derivatives, flavonoids and triterpenoids, which exert different biological activities, such as anti inflammatory, anticancer and antimicrobial. Additionally, the whole plant is recognized as safe and well tolerated by humans, with no reported adverse effects. Nowadays, dandelion is a commonly available dietary supplement and a component of pharmaceutical preparations used for the treatment of bladder, liver, and spleen. Nevertheless, the effect of dandelion on blood platelets and plasma - components of hemostasis involved in the functioning of a cardiovascular system and linked with various cardiovascular diseases, has not been studied yet. Thus, the main objective of our in vitro experiments was to examine the anti platelet and antioxidant properties of four standardized dandelion phenolic fractions, i.e. leaves 50% and 85% methanol fractions, and petals 50% and 85% methanol fractions, in blood platelets. Additionally, aforementioned plant preparations were investigated for hemostatic activity in plasma, using three selected hemostatic parameters: the activated partial thromboplastin time (APTT), prothrombin time (PT) and thrombin time (TT). None of the studied dandelion fractions, caused the damage of human blood platelets, at the whole tested range. The inhibition of lipid peroxidation in platelets treated with H2O2/Fe (the donor of OH) was observed for two fractions: leaves and petals 50% fractions, both at the dose 50 MUg/mL. Analysis of the effect on the coagulation activity of human plasma demonstrated that three fractions: petals 50% fraction, and leaves and petals 85% fractions, significantly prolonged the thrombin time, at the whole tested range. On the contrary, none of the fractions changed the APTT and the PT. The obtained results demonstrate that dandelion preparations, based on aerial parts, especially rich in hydroxycinnamic acid derivatives (leaves and petals 50% fractions) are promising plant materials exerting both antioxidant and anticoagulant activities of the hemostatic system that is beneficial in the prevention and treatment of cardiovascular diseases. PMID- 29580526 TI - Structuration of lipid bases with fully hydrogenated crambe oil and sorbitan monostearate for obtaining zero-trans/low sat fats. AB - Several studies have shown that excessive intake of trans and saturated fatty acids is associated with an increased risk of cardiovascular disease. In this context, the food industry has sought alternatives for the development of healthy lipid bases, with higher levels of unsaturated fatty acids, adapting to current legislation. The incorporation of structuring agents into liquid oils has proven to be a potential alternative for obtaining semi-plastic lipid bases with reduced levels of saturated fatty acids. Thus, the objective of this study was to produce zero trans fat bases with lower saturated fatty acids levels. Palm oil (PO) was used as a zero trans-lipid base reference because of its technological functionality. Blends containing different proportions of high oleic sunflower oil (HOSO) and PO were prepared as follows: control 100: 0; 80:20; 60:40; 40:60; 20:80; and 100: 0 PO: HOSO (w/w%), respectively. Then, 3% of fully hydrogenated crambe oil (FHCO) and 3% sorbitan monostearate (SMS) were added to the blends as structuring agents, forming the structured (S) blends. The addition of HOSO to the PO decreased the saturated fatty acids by up to 30.6%, with consequent increase of unsaturated fatty acids, especially oleic acid. The joint action of the SMS and the FCHO allowed for obtaining structured blends with plastic and spreadability characteristics, as well as modifications throughout the crystallization process of the original blends. PMID- 29580527 TI - Rapid determination of the aromatic compounds methyl-anthranilate, 2' aminoacetophenone and furaneol by GC-MS: Method validation and characterization of grape derivatives. AB - A methodology for the rapid determination of the aromatic compounds methyl anthranilate (MA), 2'-aminoacetophenone (2-AAP) and furaneol by GC-MS was validated and used to characterize grape juice and wine elaborated with the new Brazilian grape varieties cultivated in northeastern Brazil, and Brazilian grape nectars. The method presented linearity (R2 ? 0.9952), good accuracy (CV < 12.9%), recovery (76.6% to 106.3%), limit of detection (23 MUg L-1 to 94 MUg L-1) and limit of quantification (96 MUg L-1 to 277 MUg L-1) acceptable in only 20 min of running. The methodology was considered satisfactory for the purpose, being a simple and rapid method for the determination of these compounds in grape derivatives drinks. In the characterization of the nectars the compound that stood out was the MA, being its presence attributed to the addition of flavorings in these products. It was evidenced a significant contribution of furaneol in the aroma of grape juice and wines elaborated with the new Brazilian grape varieties. PMID- 29580528 TI - Sorting out the phytoprostane and phytofuran profile in vegetable oils. AB - Phytoprostanes (PhytoPs) and phytofurans (PhytoFs) are prostaglandin-like compounds, contributing to defense signaling and prevention of cellular damage. These plant oxylipins result from autoxidation of alpha-linolenic acid (ALA) and have been proposed as new bioactive compounds due to their structural analogies with isoprostanes (IsoPs) and prostanoids derived from arachidonic acid in mammals, which have demonstrated diverse biological activities. The present work assesses a wide range of vegetable oils - including extra virgin olive oils (n = 7) and flax, sesame, argan, safflower seed, grapeseed, and palm oils - for their content of PhytoPs and PhytoFs. Flax oil displayed the highest concentrations, being notable the presence of 9-epi-9-D1t-PhytoP, 9-D1t-PhytoP, 16-B1-PhytoP, and 9-L1-PhytoP (7.54, 28.09, 28.67, and 19.22 MUg mL-1, respectively), which contributed to a total PhytoPs concentration of 119.15 MUg mL-1, and of ent-16 (RS)-9-epi-ST-Delta14-10-PhytoF (21.46 MUg mL-1). Palm and grapeseed oils appeared as the most appropriate negative controls, given the near absence of PhytoPs and PhytoFs (lower than 0.15 MUg mL-1). These data inform on the chance to develop nutritional trials using flax and grapeseed oils as food matrices that would provide practical information to design further assays intended to determine the actual bioavailability/bioactivity in vivo.

AB - This study investigated the chemical and nutritional composition of breakfast cereal based on whole sorghum, and the effect of its association with unfermented probiotic milk on the inflammation and oxidative stress of individuals with chronic kidney disease. Extruded sorghum breakfast meal presented higher carbohydrate concentration (approximately 71%), followed by protein (approximately 11%) and lipid (approximately 0.4%). When compared to extruded maize breakfast meal, it presented higher percentage of dietary fiber (p < 0.05), and higher content of phenolic compounds and tannin, consequently higher antioxidant activity (p < 0.05). Extruded sorghum breakfast cereal combined with unfermented probiotic milk decreased the C-reactive protein (p < 0.05) and malondialdehyde (p < 0.05) serum levels and increased the total antioxidant capacity and superoxide dismutase (p < 0.05) in patients with chronic kidney disease. Therefore, the extruded sorghum, source of tannin, anthocyanin, and dietary fiber, when consumed with unfermented probiotic milk alleviates the inflammation and oxidative stress in patients with chronic kidney disease. PMID- 29580530 TI - Gazing behavior reactions of Vietnamese and Austrian consumers to Austrian wafers and their relations to wanting, expected and tasted liking. AB - Predictability of consumers' food choice based on their gazing behavior using eye tracking has been shown and discussed in recent research. By applying this observational technique and conventional methods on a specific food product, this study aims at investigating consumers' reactions associated with gazing behavior, wanting, building up expectations, and the experience of tasting. The tested food products were wafers from Austria with hazelnut, whole wheat, lemon and vanilla flavors, which are very well known in Austria and not known in Vietnam. 114 Vietnamese and 128 Austrian participants took part in three sections: The results indicate that: i) the gazing behavior parameters are highly correlated in a positive way with the wanting-to-try choice; ii) wanting to try is in compliance with the expected liking for the Austrian consumer panel only, which is very familiar with the products; iii) the expected and tasted liking of the products are highly country and product dependent. The expected liking is strongly correlated with the tasted liking for the Austrian panel only. Differences between the reactions of the Vietnamese and Austrian consumers are discussed in detail. The results, which reflect the complex process from gazing for "wanting to try" to the expected and tasted liking, are discussed in the context of the cognitive theory and food choice habits of the consumers. PMID- 29580531 TI - Changes of free-form volatile compounds in pre-treated raisins with different packaging materials during storage. AB - The aroma profiles of volatile compounds (VOCs) were analyzed by GC/MS in pre treated air-dried (PAD) and sun-dried (PSD) raisins during storage. Total 98, 94 and 81 VOCs were identified in Zixiang Seedless raisins (ZSRs), Centennial Seedless raisins (CSRs) and Thompson Seedless raisins (TSRs), respectively. During storage, the overall concentrations of VOCs of PSD raisins were higher in plastic bag (PB) compared to those in woven bag (WB). Regarding fruity and floral aromas, the effect of PAD and PB was significant throughout the storage periods (3, 6 and 9 months), however, fatty aroma was higher in PSD raisins due to the major contribution of 2,3-butanedione. The main fruity and floral aroma contributors were beta-damascenone, limonene, rose oxide, geraniol and ethyl hexanoate. This study showed that compounds came from unsaturated fatty acid oxidation, glycosidically-derived and grape-derived source were contributed to fruity, floral or herbaceous aromas, but Maillard reaction-derived VOCs imparted fatty and roasted aromas. PMID- 29580532 TI - Changes in levels of phytic acid, lectins and oxalates during soaking and cooking of Canadian pulses. AB - Raw and processed (soaked or cooked) seeds of peas, lentils, chickpeas, fava beans and common beans were studied for their contents of antinutritional factors (lectins, phytic acid, total and soluble oxalates), along with soybean as a control. Analysis of variance indicated that legume type, treatment and their interactive effects were significant on these antinutrients. The raw soybean seed was found to contain the highest levels of lectins (692.8 HU/mg), phytic acid (22.91 mg/g), total oxalate (370.5 mg/100 g) and soluble oxalate (200.7 mg/100 g) among all investigated seeds. Relatively high contents of lectins were detected in beans (87.69-88.59 HU/mg) and other pulses ranging from 2.73-11.07 HU/mg. Phytic acid in Canadian pulses varied slightly from 8.55-22.85 mg/g. Total oxalates were variable, ranging from 244.7-294.0 mg/100 g in peas, 168.6-289.1 mg/100 g in lentils, 241.5-291.4 mg/100 g in fava beans, 92.2-214.0 mg/100 g in chickpeas and 98.86-117.0 mg/100 g in common beans. Approximately 24-72% of total oxalate appeared to be soluble in all investigated pulses. Soaking the seeds in distilled water significantly decreased the contents of lectins (0.11-5.18%), total oxalate (17.40-51.89%) and soluble oxalate (26.66-56.29%), but had no impact on phytic acid. The cooking process was found to be more effective in reducing levels of all the investigated antinutritional factors, except phytic acid in common beans and soybean. PMID- 29580533 TI - Product reformulation in the context of nutritional warning labels: Exploration of consumer preferences towards food concepts in three food categories. AB - The reformulation of the food products available in the marketplace to improve their nutritional quality has been identified as one of the most cost-effective policies for controlling the global obesity pandemic. Front-of-pack (FOP) nutrition labelling is one of the strategies that has been suggested to encourage the food industry to reformulate their products. However, the extent to which certain FOP labels can encourage product reformulation is dependent on consumer reaction. The aim of the present work was to assess consumers' perception towards product reformulation in the context of the implementation of nutritional warnings, an interpretive FOP nutrition labelling scheme. Three product categories were selected as target products: bread, cream cheese and yogurt, each associated with high content of one target nutrient. For each category, six packages were designed using a 3 * 2 experimental design with the following variables: product version (regular, nutrient-reduced and nutrient-free) and brand (market leader and non-market leader). A total 306 Uruguayan participants completed a choice experiment with 18 choice sets. Reformulated products without nutritional warnings were preferred by participants compared to regular products with nutritional warnings. No apparent preference for products reformulated into nutrient-reduced or nutrient-free product versions was found, although differences depended on the product category and the specific reformulation strategy. Preference for reformulated products without nutritional warnings was more pronounced for non-market leaders. Results from the present work suggest that reformulation of foods in the context of the implementation of nutritional warnings holds potential to encourage consumers to make more healthful food choices and to cause a reduction of their intake of nutrients associated with non communicable diseases. PMID- 29580534 TI - Assessment of cocoa (Theobroma cacao L.) butter content and composition throughout fermentations. AB - Cocoa fermentation is a crucial step for the development of cocoa aroma and precursors of high quality cocoa and by-products. This bioprocess has been studied for years to understand cocoa chemical changes but some matters concerning changes in fat content remain that are investigated in this work. Changes in the quantity (free and total fat), extractability and composition of cocoa butter were assessed in samples from Madagascar, the Dominican Republic and Ecuador. Increases in free fat content were highlighted in samples from each origin thanks to the use of the 'soxtec' solvent method, which preserves the integrity of the butter. A 4.71% increase in free fat was measured in the Ecuadorian samples fermented for 144 h. Conversely, total fat content remained stable throughout fermentation. Protein and polyphenol contents decreases were linked to fat content augmentation by a strong negative interaction. Triglyceride and total and linked fatty acid kinetics (0 to 6 days) of the butter remained statistically stable during fermentation, as did unsaponifiable matter. The origin of fermentation had a predominant and significant impact on composition, revealed by PCA. This work underlines and explains the importance of fermentation process in improving yield of fat that can be extracted while preserving the composition of this cocoa butter. This study highlights an interaction in cocoa unfermented or partially fermented beans. This phenomenon causes butter content retention but is slowly broken after 72 h fermentation. Therefore, fermentation appears to be also necessary to enhance the cocoa butter content extracted from the nibs.

AB - Konjac glucomannan (KGM) is a natural polysaccharide with several favorable nutritional characteristics, and exhibits functional properties as a potential fat-replacer in dairy products. In our study, composition, color and browning (L*, a* and b* before and after heating), and textural characteristics of low-fat and skimmed Mozzarella cheese with KGM (LFKGM and SKKGM) were compared with those of full-fat, low-fat and skimmed Mozzarella cheese controls (FFC, LFC and SKC) after 0, 7, 14, 21 and 28 days of storage at 4 degrees C. In general, LFKGM and SKKGM had similar composition to LFC and SKC, respectively, except that LFKGM had higher moisture than LFC and SKKGM had high aw than SKC. The LFKGM and SKKGM had higher L* (lightness) than LFC and SKC, respectively, and LFKGM had similar whiteness to FFC before and after heating. However, the browning factor was not affected by KGM addition. The a* values (greenness) of LFKGM and SKKGM were more negative than for LFC and SKC before and after heating. The b* values (yellowness) of LFKGM and SKKGM were higher than LFC and SKC, respectively. Grated SKKGM exhibited lower firmness than SKC, and LFKGM exhibited higher stickiness than LFC. The melted LFKGM and SKKGM had similar resistance and stretch quality to LFC and SKC when they were stretched, respectively. The changes in the lightness, moisture and firmness as affected by KGM addition in the cheeses were more close to those of full-fat cheese compared with the cheeses without KGM, indicating KGM would be a potential fat replacer to be used in Mozzarella cheese. PMID- 29580537 TI - Combined high-power ultrasound and high-pressure homogenization nanoemulsification: The effect of energy density, oil content and emulsifier type and content. AB - Combinations of ultrasound (US) and high-pressure homogenization (HPH) at low medium energy densities were studied as alternative processes to individual US and HPH to produce Tween 80 and whey protein stabilized nanoemulsions, while reducing the energy input. To this aim, preliminary trials were performed to compare emulsification efficacy of single and combined HPH and US treatments delivering low-medium energy densities. Results highlighted the efficacy of US HPH combined process in reducing the energy required to produce nanoemulsions stabilized with both Tween 80 and whey protein isolate. Subsequently, the effect of emulsifier content (1-3% w/w), oil amount (10-20% w/w) and energy density (47 175 MJ/m3) on emulsion mean particle diameter was evaluated by means of a central composite design. Particles of 140-190 nm were obtained by delivering 175 MJ/m3 energy density at emulsions containing 3% (w/w) Tween 80 and 10% (w/w) oil. In the case of whey protein isolate stabilized emulsions, a reduced emulsifier amount (1% w/w) and intermediate energy density (120 MJ/m3) allowed a minimum droplet size around 220-250 nm to be achieved. Results showed that, in both cases, at least 50% of the energy density should be delivered by HPH to obtain the minimum particle diameter. PMID- 29580538 TI - Alfalfa but not milk in lamb's diet improves meat fatty acid profile and alpha tocopherol content. AB - To establish animal feeding recommendations, it is required to quantify whether the effects of combining dietary alfalfa and milk on meat composition of light lambs are overlapped or independent. This experiment aimed to evaluate the separate effects of dietary alfalfa and milk access on the light lamb carcass quality (10-11 kg), meat colour, chemical composition, fatty acid profile and alpha-tocopherol content. Thirty-two lambs were assigned to one of four treatments in a 2 * 2 factorial design. The factors were the inclusion of dietary forage (grazed alfalfa vs. concentrate-fed indoors) and lactation length (weaning at a target live-weight of 13 kg vs. suckling until slaughter at 22-24 kg). Dietary alfalfa but not milk supply improved conjugated linoleic acid isomers (CLA), omega-3 fatty acids and alpha-tocopherol contents in lamb meat without affecting meat colour attributes. Milk supply affected more the fatty acid profile (more saturated) than the alpha-tocopherol content of meat. Thus, dietary alfalfa improved CLA, omega-3 fatty acids and alpha-tocopherol content in light lamb without affecting the meat colour, whereas lengthening the lactation period did not provide benefits in terms of meat colour or healthy nutrient composition.

PMID- 29580540 TI - Chemical composition of kale as influenced by dry vermicast, potassium humate and volcanic minerals. AB - Biofortification using agronomic practices can be used to improve the nutritional quality of food crops. Three natural media amendments (dry vermicast, potassium (K)-humate and volcanic minerals) were assessed under greenhouse conditions to determine the effects on the chemical composition of kale (Brassica oleracea L. var. acephala 'Ripbor'). The results indicated that K-humate had low pH, while the volcanic minerals had high pH. Plants grown in the dry vermicast amended media had the highest levels of macronutrients and micronutrients except for zinc and iron. However, the glycolipid: phospholipid ratio was lower in kale plants cultivated in dry vermicast compared to plants cultivated in the volcanic minerals or K-humate. Conversely, plants cultivated in the dry vermicast had enhanced levels of polyunsaturated fatty acids. The omega-3 fatty acid content was significantly (P < 0.05) higher in plants cultivated in dry vermicast and potassium humate, while the omega-6 fatty acids were unaffected by media amendments. Dry vermicast was the most effective at increasing plant tissue oleic acid content. The total phenolic content and antioxidant capacity were highest in plants treated with K-humate, but lowest in the dry vermicast treated plants. In conclusion, dry vermicast proved to be the most effective in enhancing the phytochemical composition of kale 'Ripbor'. These results suggest dry vermicast could be a potential target natural media amendment for biofortifying kale plants during cultivation. PMID- 29580541 TI - Wild Lonicera caerulea berry polyphenol extract reduces cholesterol accumulation and enhances antioxidant capacity in vitro and in vivo. AB - The hypocholesterolemic effect of Lonicera caerulea berry extract rich in polyphenols (LCBP) on high cholesterol-induced hypercholesterolemia and lipoprotein metabolite changes was examined in Caco-2 cells and rats. Cyanidin-3 glucoside, catechin, and chlorogenic acid are the major phenolic components of LCBP. The cholesterol-reducing effect and antioxidant capacity of these components were compared in Caco-2 cells. LCBP (80 MUg/mL) and cyanidin-3 glucoside, catechin, and chlorogenic acid (50 MUM) were found to be effective (p < 0.05). Rats were fed a high cholesterol diet (HCD) with or without LCBP supplementation (75, 150, and 300 mg/kg body weight intragastrically once daily) for 12 weeks. Compared with the HCD control group, LCBP supplementation at 150 and 300 mg/kg decreased the levels of TC, TG, and LDL-C, but increased that of HDL-C. LCBP treatment promoted greater neutral and acidic sterol excretion (p < 0.05) and improved the antioxidant capacity of the colon tissue, colon contents, and blood. Moreover, trimethylamine N-oxide (TMAO) levels were decreased in serum (p < 0.05). NPC1L1, ACAT2, and MTP mRNA and protein expression were reduced and ABCG5/8 expression was increased (p < 0.05) after LCBP treatment. Our results suggest that LCBP could be used as a functional food for the prevention and treatment of diseases related to excessive cholesterol accumulation.

AB - The effects of ethanol (up to 20 wt%) on the rheological properties and structural characteristics of kappa-carrageenan gel were investigated by Field Emission Scanning Electron Microscopy (FESEM) and Small Angle X-ray Scattering (SAXS). Both the sol-gel and gel-sol transition temperatures shifted to higher degree (from 36.8 +/- 0.5 to 52.5 +/- 1.4 degrees C and from 51.2 +/- 0.6 to 67.0 +/- 0.5 degrees C, respectively) upon 20 wt% ethanol addition (P < 0.05). The critical relaxation exponent n and the critical gel strength Sg obtained from Winter-Chambon criterion decreased and increased, respectively as the ethanol concentration increased. The kappa-carrageenan gel was formed due to the formation of fibrillar networks, and the fibrillar density increased upon ethanol addition via FESEM. Moreover, upon 20 wt% ethanol addition, the average radius of gyration of kappa-carrageenan strand increased from 1.18 +/- 0.03 of control to 1.55 +/- 0.02 nm by SAXS. A mechanism underlying the effect of ethanol on the kappa-carrageenan gelation was proposed based on coil to double helix transition followed by the helix aggregation. PMID- 29580543 TI - The relevance of supply chain characteristics in GHG emissions: The carbon footprint of Maltese juices. AB - AIMS: Foods and drinks are major contributors (17%) to the greenhouse gas (GHG) emissions caused by private consumption in Europe. The carbon footprint (CF) of a certain product expresses the total GHG emissions over its whole life cycle, and its calculation for foodstuff is a necessary first step to reduce their contribution to global warming. The calculation of the CF of Maltese food products is especially relevant for two reasons: the economic characteristics of the island, whose food sector is highly dependent on imports, implying longer transport distances; and the Maltese electricity production mix, based almost exclusively on oil combustion. METHODS AND RESULTS: The CF of ten multi-fruit juices marketed in Malta has been determined, covering all the processes from the agricultural stage to the distribution of the final products. As a functional unit (FU), a 250 ml bottle of packaged product arriving at the retailer has been considered. The Maltese orange juice, the only final product in which only local ingredients are used, presents the lowest CF (0.50 kgCO2/FU), while the remaining ones range from 0.67 kgCO2/FU to 0.80 kgCO2/FU. The major contributor to all the CFs is juice processing at the Maltese plant (0.42 kgCO2/FU), mainly due to the use of electricity (78%). CONCLUSIONS: The influence of both the electricity mix and the Maltese supply chain in the CF of the final products has been demonstrated. Alternatives to reduce the impacts of the final products have been proposed and evaluated that could lower the average CF of the juices by 32%. SIGNIFICANCE AND IMPACT OF THE STUDY: The calculation of the CF of Maltese juices represents an innovative case study due to the characteristics of the island, and it is expected to act as a first step to lower their environmental impacts. PMID- 29580544 TI - High voltage electrical discharges combined with enzymatic hydrolysis for extraction of polyphenols and fermentable sugars from orange peels. AB - Orange peels are a biomass rich in carbohydrates and polyphenols and characterized by their low lignin content. This work focuses on finding the best combination between physical and biological treatments to enhance the extraction of fermentable sugars and polyphenols. High voltage electrical discharges (HVED) (0 to 900 kJ/kg) or enzymatic hydrolysis with Viscozyme(r) L (12 FBGU/g) were applied on fresh or defatted orange peels for the extraction of polyphenols and fermentable sugars. An HVED energy input of 222 kJ/kg was optimal for the extraction of reducing sugars (19 g/100 g DM) and polyphenols (0.7 g/100 g DM). However, enzymatic hydrolysis allowed a higher extraction of reducing sugars (50 g/100 g DM). HVED were then applied prior or simultaneously to enzymatic hydrolysis to maximize the extraction of biomolecules from orange peels. Thus, the results clearly showed that the HVED pretreatment of orange peels is efficient to enhance the accessibility of cellulosic biomass to enzymes. HVED (222 kJ/kg) prior to enzymatic hydrolysis (12 FBGU/g), was the most effective combination of these two processes to get an intensive extraction of biomolecules from orange peels.

AB - In the last years, there has been a growing interest in the use of edible materials in food packaging. The cheese industry is clearly one of the sectors where these materials have a good opportunity for application, as shown by the recent developments on edible coatings and films for cheese. Edible coatings and films, besides its edibility, can be used to reduce weight loss and prevent the microbiological spoilage through the control of oxygen and carbon dioxide exchange rate and as a carrier of antimicrobial compounds. This review summarizes the recent results on edible films and coatings for cheese, the main developments and the main future perspectives for the application of these materials in the cheese industry. PMID- 29580547 TI - Preparation and cellular protection against oxidation of Konjac oligosaccharides obtained by combination of gamma-irradiation and enzymatic hydrolysis. AB - Konjac glucomannan (KGM) is an important source for preparation of Konjac oligo glucomannan (KOG), but high molecular weight and viscosity in KGM inhibited its full degradation into KOG. In this study, KOG with a degree of polymerization between 2 and 9 was obtained by combining gamma-irradiation and enzymatic hydrolysis in high yield. We investigated the protective effect of KOG against H2O2 - induced oxidative damage in vitro, using human hepatic cell line (LO2) as a cell model. Our results demonstrated that pretreating LO2 with KOG significantly increases cellular survival and antioxidant activities of GSH-Px and CAT enzymes, and reduces levels of LDH, MDA, intracellular accumulation of ROS and Ca2+ concentration within the cell. Marked protective effect against oxidative damage, in addition to obtained high yield of KOG, supports its potential use as an abundant source of antioxidant. To conclude, our study provided a theoretical perspective for future uses of KGM. PMID- 29580548 TI - Analysis of an old controversy: The compensation temperature for micellization of surfactants. AB - The actual significance of the so-called compensation temperature Tc for micellization of surfactants is reviewed. It is demonstrated that it is possible to obtain as many Tc values as the number of temperature intervals in which the dependencies of enthalpy and entropy changes with temperature are analyzed. The value of each Tc will be the central value To of each temperature interval. These two facts suggest that Tc is simply such experimental To. Thus any physical interpretation derived from Tc is unfounded. PMID- 29580549 TI - Improving the psychometric properties of dot-probe attention measures using response-based computation. AB - BACKGROUND AND OBJECTIVES: Abnormal threat-related attention in anxiety disorders is most commonly assessed and modified using the dot-probe paradigm; however, poor psychometric properties of reaction-time measures may contribute to inconsistencies across studies. Typically, standard attention measures are derived using average reaction-times obtained in experimentally-defined conditions. However, current approaches based on experimentally-defined conditions are limited. In this study, the psychometric properties of a novel response-based computation approach to analyze dot-probe data are compared to standard measures of attention. METHODS: 148 adults (19.19 +/- 1.42 years, 84 women) completed a standardized dot-probe task including threatening and neutral faces. We generated both standard and response-based measures of attention bias, attentional orientation, and attentional disengagement. We compared overall internal consistency, number of trials necessary to reach internal consistency, test-retest reliability (n = 72), and criterion validity obtained using each approach. RESULTS: Compared to standard attention measures, response-based measures demonstrated uniformly high levels of internal consistency with relatively few trials and varying improvements in test-retest reliability. Additionally, response-based measures demonstrated specific evidence of anxiety related associations above and beyond both standard attention measures and other confounds. LIMITATIONS: Future studies are necessary to validate this approach in clinical samples. CONCLUSIONS: Response-based attention measures demonstrate superior psychometric properties compared to standard attention measures, which may improve the detection of anxiety-related associations and treatment-related changes in clinical samples.

PMID- 29580551 TI - Determination of Dynamical Heterogeneity from Dynamic Neutron Scattering of Proteins. AB - Motional displacements of hydrogen (H) in proteins can be measured using incoherent neutron-scattering methods. These displacements can also be calculated numerically using data from molecular dynamics simulations. An enormous amount of data on the average mean-square motional displacement (MSD) of H as a function of protein temperature, hydration, and other conditions has been collected. H resides in a wide spectrum of sites in a protein. Some H are tightly bound to molecular chains, and the H motion is dictated by that of the chain. Other H are quite independent. As a result, there is a distribution of motions and MSDs of H within a protein that is denoted dynamical heterogeneity. The goal of this paper is to incorporate a distribution of MSDs into models of the H incoherent intermediate scattering function, I(Q,t), that is calculated and observed. The aim is to contribute information on the distribution as well as on the average MSD from comparison of the models with simulations and experiment. For example, we find that simulations of I(Q,t) in lysozyme are well reproduced if the distribution of MSDs is bimodal with two broad peaks rather than a single broad peak. PMID- 29580553 TI - Karyotype classification, clinical manifestations and outcome in 124 Turner syndrome patients in China. AB - OBJECTIVE: To investigate the karyotype, clinical manifestations and natural and therapeutic outcome of Turner syndrome (TS) in China. METHOD: A total of 124 TS patients with definite diagnosis were included. Karyotype, main clinical signs, sexual development and therapeutic outcome were analyzed. RESULTS: TS karyotype was classified in 4 types: monosomy (32.7%), mosaic (15.9%), variant (23.9%) and mosaic with variant (27.4%). All patients showed short stature, with mean adult height<145cm. Sixteen percent of adolescent patients showed spontaneous breast development and 8% spontaneous menstruation. The rate of spontaneous sexual development was lowest in the monosomy karyotype. Common signs included cubitus valgus and wide breast space in about 50% of patients, epicanthus and skin nevus in 30% and webbed neck and shield chest in 10-20%. More than 10% of patients had associated heart, kidney or thyroid abnormalities. The rate of kidney malformation was highest in the monosomy karyotype. Growth hormone (GH) therapy can accelerate growth, with 7.6cm and 6.7cm increase in height in the first and second years of therapy respectively, slowing to 5.7cm and 4.1cm in the third and fourth years. Treated patients who reached nearly adult height were 10.2cm taller than untreated patients. Therapeutic effect correlated with GH therapy duration. CONCLUSION: TS patients showed a variety of karyotypes, related to the diversity of clinical manifestations and outcomes. Sexual development and adult height were poorer in monosomy karyotypes than in other types. PMID- 29580552 TI - Evidence for DNA Sequence Encoding of an Accessible Nucleosomal Array across Vertebrates. AB - Nucleosome-depleted regions around which nucleosomes order following the "statistical" positioning scenario were recently shown to be encoded in the DNA sequence in human. This intrinsic nucleosomal ordering strongly correlates with oscillations in the local GC content as well as with the interspecies and intraspecies mutation profiles, revealing the existence of both positive and negative selection. In this letter, we show that these predicted nucleosome inhibitory energy barriers (NIEBs) with compacted neighboring nucleosomes are indeed ubiquitous to all vertebrates tested. These 1 kb-sized chromatin patterns are widely distributed along vertebrate chromosomes, overall covering more than a third of the genome. We have previously observed in human deviations from neutral evolution at these genome-wide distributed regions, which we interpreted as a possible indication of the selection of an open, accessible, and dynamic nucleosomal array to constitutively facilitate the epigenetic regulation of nuclear functions in a cell-type-specific manner. As a first, very appealing observation supporting this hypothesis, we report evidence of a strong association between NIEB borders and the poly(A) tails of Alu sequences in human. These results suggest that NIEBs provide adequate chromatin patterns favorable to the integration of Alu retrotransposons and, more generally to various transposable elements in the genomes of primates and other vertebrates. PMID- 29580554 TI - Paramunity-inducing Factors (PINDs) in dendritic cell (DC) cultures lead to impaired antileukemic functionality of DC-stimulated T-cells. AB - INTRODUCTION: Paramunity-inducing-Factors (PINDs) consist of attenuated/inactivated viruses of various poxvirus-genera, used in veterinary medicine as non-antigen-specific, non-immunising stimulators of the innate immune system against infectious and malignant diseases. Their danger-signaling interactions were tested for their capacity to improve leukemic antigen presentation on DC generated from AML-patients' blasts ('DCleu') and DC stimulation/activation of antileukemic T-cells. METHODS: We analyzed, whether the addition of PINDs during DC cultures (15 healthy, 22 leukemic donors) and mixed lymphocyte culture (MLC, n = 15) with autologous (n = 6), allogeneic (n = 2) or T cells after stem cell transplantation (SCT; n = 7) would alter the quality and quantity of DC, the composition of T-cell-subsets, and/or their antileukemic functionality (AF) as studied by FACS and functional Fluorolysis-cytotoxicity assays. RESULTS: Effects on 1. DC-cultures: PINDs in DC-cultures lead to increased proportions of mature DC and DCleu, but reduced proportions of viable and overall, as well as TLR4- and TLR9-expressing DC. 2. MLC: PINDs increased early (CD8+) T-cell activation (CD69+), but reduced proportions of effector-T cells after MLC 3. AF: Presence of PINDs in DC- and MLC-cultures reduced T-cells' as well as innate cells' antileukemic functionality. 4. Cytokine-release profile: Supernatants from PIND-treated DC- and MLC-cultures resembled an inhibitory microenvironment, correlating with impaired blast lysis. CONCLUSIONS: Our data shows that addition of PINDs to DC-cultures and MLC result in a "blast-protective capacity" leading to impaired AF, likely due to changes in the composition of T /innate effector cells and the induction of an inhibitory microenvironment. PINDs might be promising in treating infectious diseases, but cannot be recommended for the treatment of AML-patients due to their inhibitory influence on antileukemic functionality.

AB - INTRODUCTION: This study evaluated the effect of resident involvement on patient outcomes following major ventral hernia repair (VHR). METHODS: National Surgical Quality Improvement Program database was queried to identify patients with major VHR between 2007 and 2010. Patient outcomes were compared based on presence or absence of resident in the operating room. RESULTS: Residents participated in 57% of the 27,773 identified cases. There was no significant difference in return to operating room or 30-day mortality. A higher incidence of superficial surgical site infection (SSI) (4.9% vs 3.9%, P = 0.013) and longer operative time (129.2 vs 99.1 min, P < 0.001) were observed with resident involvement in open inpatient cases. We found no evidence of a "July effect" on outcomes. CONCLUSION: Resident involvement in VHR has little impact on morbidity, and patients can be reassured that resident participation in their care is safe. PMID- 29580558 TI - Prevalence and Predictors of Depression Among Patients With Epilepsy, Stroke, and Multiple Sclerosis Using the Cleveland Clinic Knowledge Program Within the Neurological Institute. AB - BACKGROUND: Neurological conditions carry a high risk of depression. Given this risk, the Neurological Institute (NI) at Cleveland Clinic has initiated systematic screening for depression using the 9-item Patient Health Questionnaire 9 (PHQ-9) embedded within its electronic medical record and its data capture system, the Knowledge Program (KP)1. OBJECTIVE: We sought to (1) estimate the prevalence of depression among patients with epilepsy, stroke, and multiple sclerosis (MS); (2) identify risk factors for depression within each disease; and (3) determine differential risks and predictors across neurological disorders. METHODS: The KP1 database provided information on approximately 23,000 visits involving 7946 outpatients with epilepsy, stroke, or MS seen in neurology specialty clinics. The primary outcome measure was depression as defined as a PHQ 9 >= 10. RESULTS: Overall, the point prevalence of depression was 29.0%. For stroke, epilepsy, and MS, prevalence of depression was 23% (95% CI: 21-25%), 33% (95% CI: 31-35%), and 29% (95% CI: 28-30%), respectively. For all 3 conditions, increasing disease severity and decreased health-related quality of life were independent predictors of depression. In multivariable models, there was a significant interaction between age and condition, and condition with disease severity. In stroke and MS, increasing age was associated with reduced odds for depression, whereas in epilepsy, increasing age was associated with an increased odds for depression. CONCLUSIONS: Although depression is common among patients with neurological disorders, our data suggest that predictors of depression such as age and disease severity varied by condition, supporting important possible phenomenological and pathophysiological differences of depression across these neurological conditions. PMID- 29580559 TI - Microplastics in freshwater systems: A review on occurrence, environmental effects, and methods for microplastics detection. AB - The continuous increase in synthetic plastic production and poor management in plastic waste have led to a tremendous increase in the dumping into our aqueous environment. Consequently, microplastics commonly defined as sizes less than 5 mm are produced and stay in both seawater and freshwater environment. The presence of microplastics as a new type of emerging contaminant has become a great issue of concerns from public and government authorities. The sources of microplastics to freshwater systems are many with the largest portion from wastewater treatment plants. The abundance of microplastics varies with the location, from above 1 million pieces per cubic meter to less than 1 piece in 100 cubic meters. Microplastics can cause several harmful physical effects on humans and living organisms through such mechanisms as entanglement and ingestion. The microplastics can act as carriers of various toxins such as additives from industrial production processes and persistent contaminants by the sorption in waters. Those toxins may cause great health problems to humans. A few studies on the fishes demonstrated that the microplastics and the associated toxins are bio accumulated and cause such problems as intestinal damage and change in metabolic profiles. In studies of microplastics, fresh water is first sampled by the nets with typical mesh size of 330 MUm for collection of microplastics. After the volume reducing process, the samples will then go through the purification process including density separation by such inorganic salts as sodium chloride and digestion process by oxidizing agents or enzymes. The sequence of these two processes (namely purification and digestion) is dependent on the sample type. The purified samples can be studied by several analytical methods. The commonly used methods for the qualification studies are FTIR spectroscopy, Raman spectroscopy, pyrolysis-GC/MS, and liquid chromatography. A tagging method can be used in the quantification study. Our literature study finds that there is still no universal accepted quantification and qualification tools of microplastics in fresh waters. More work is anticipated so as to obtain accurate information on microplastics in freshwater, which can then be used for the better assessment of the environmental risk. PMID- 29580560 TI - Understanding implementation and uptake in the National Health Service Health Check Programme. AB - OBJECTIVES: We present findings from a national online survey of uptake and implementation of the National Health Service Health Check (NHSHC) programme. The research aimed to understand national variation in implementation of NHSHCs and to explore the relationship between uptake and different components of implementation. STUDY DESIGN: The study design was a descriptive online survey. METHODS: Data were collected via an online survey between November 2015 and August 2016. The survey was distributed nationally to practice managers in the Midlands and East of England, South of England, North of England and London via local NHSHC leads with the help of the national programme manager. RESULTS: Responses were received from 153 participants, half of who were practice managers (49.7%). Common components of implementation included using postal invitations accompanied by the national leaflet, delivering NHSHCs routinely with other appointments, offering NHSHC outside of working hours and taking blood samples during the consultation. Meaningful exploration of the relationship between uptake and components of implementation was not possible given the inaccuracy of self-reported uptake data, which was confirmed by comparison with public health data in a subsample (n = 18). The comparison also found that a number of practices were reporting more completed health checks than the total number of patients invited, which again indicates problems that may have implications for uptake figures locally and nationally. CONCLUSIONS: Overall, our findings showed considerable variation in the implementation of NHSHCs on a national scale and issues with quality of programme uptake data, which has implications for national reporting for NHSHC. PMID- 29580561 TI - Association between bedtime and self-reported illness among college students: a representative nationwide study of China. AB - OBJECTIVE: This study was to examine the association between bedtime and self reported illness among Chinese college students. METHODS: Participants were 11,942 students, who were identified through a multistage survey sampling process. Sleep and illness status were obtained by self report. Both unadjusted and adjusted methods were considered in the analyses. RESULTS: The logistic regression model found that late bedtime was positively associated with self reported short and long-term illness (OR: 3.70 and 1, 79) after adjusting for demographic characteristics, short sleep duration, and mental disorders. CONCLUSIONS: This study is the first to find a positive relationship between late bedtime and self reported illnesses in China or elsewhere. The findings underscore the importance of educating college students about the importance of sleep.

AB - This clinical report describes the prosthetic rehabilitation of a patient with a mandibular implant-supported complete fixed dental prosthesis with limited interocclusal restorative space. The problem was manifested by repeated fractures of the acrylic resin teeth and distortion of the supporting framework. The definitive restoration included a custom computer-aided design and computer-aided manufacturing (CAD-CAM) titanium framework with the lingual cusps and most of the occlusal table of the mandibular posterior teeth milled in titanium as part of the framework. An esthetic CAD-CAM milled denture base along with teeth was bonded over this framework. PMID- 29580563 TI - Predictors of health-related quality of life in chronically ill children and adolescents over time. AB - OBJECTIVE: This study aims at identifying predictors of generic health-related quality of life (HRQoL) in chronically ill children and adolescents over time. The newly developed computer-adaptive test Kids-CAT was used to assess five dimensions of HRQoL. METHODS: Longitudinal data from the Kids-CAT study on children and adolescents with asthma, diabetes and juvenile arthritis (n = 248; aged 7-17 years) were assessed at three measurement points over six months. Individual growth modeling served to investigate effects of sociodemographic, disease- and health-related as well as psychosocial factors on HRQoL dimensions Physical Well-Being (WB), Psychological WB, Parent Relations, Social Support & Peers, and School WB over time. RESULTS: Besides effects of sociodemographic variables on HRQoL dimensions Social Support & Peers as well as School WB, we found that a longer duration of the disease was associated with better Physical WB. Lower scores were found for patients with juvenile arthritis compared to those with diabetes in HRQoL dimensions Physical WB and Social Support & Peers. Disease control was positively related to Physical and Psychological WB over time. Mental health problems were negatively associated with four, and subjective health complaints with all five HRQoL dimensions over time. Parental mental health was positively related to the patients' HRQoL score in Parent Relations over time. CONCLUSIONS: HRQoL as a multidimensional construct is associated with a wide range of different factors. Pediatricians should consider potential mental health problems and subjective health complaints in their patients. Finally, parental HRQoL can affect HRQoL in chronically ill children and adolescents. PMID- 29580564 TI - Clinical value of autoantibodies for lupus myelitis and its subtypes: A systematic review. AB - OBJECTIVE: We conducted a systematic review to investigate the clinical value of clinical characteristics and autoantibodies, especially lupus-specific antibodies, for lupus myelitis and its subtypes. METHODS: We searched PubMed, EMBASE, and ICHUSHI without language restrictions for case reports or series of lupus myelitis. We focused on cases reported since 1997, when the revised classification criteria for systemic lupus erythematosus were published. Associations between patient characteristics including autoantibodies and functional outcome, survival, subtypes of myelitis (grey and white matter myelitis), and treatment were examined. We attempted to contact authors to supplement missing information for analysis. RESULTS: Our search identified 224 cases from 105 articles. White matter myelitis predicted favorable function (odds ratio = 15.18; 99% confidence interval, 3.09-151.31; p < 0.0001). Grey matter myelitis was associated with longitudinally extensive transverse myelitis (p < 0.001) and anti-double-stranded DNA (p = 0.003), and tended to be associated with anti-beta2-glycoprotein I (p = 0.011). White matter myelitis tended to be associated with optic neuritis and anti-neuromyelitis optica antibodies. Although our study might be susceptible to under-reporting of original cases and selection bias, we aimed to provide a conservative interpretation by setting the statistical significance threshold at p < 0.01. CONCLUSIONS: This systematic review confirmed that grey matter myelitis predicted poor functional outcome and was associated with longitudinally extensive transverse myelitis and anti-double stranded DNA antibodies. White matter myelitis was associated with favorable functional outcomes and may partially represent a complication of neuromyelitis optica.

AB - INTRODUCTION: Migraine is ranked as the seventh leading cause of disability worldwide, and it is characterized by a manifestation of combined neurological, gastrointestinal, and autonomic symptoms linked with different provoking factors. AIM OF THE STUDY: This study investigates the association between migraine and PTSD, depression and anxiety in the Kosovo population during the post-war period. MATERIAL AND METHODS: 273 war survivors with headache were enrolled in the study and were divided into two groups: 153 individuals with confirmed migraine (the study group) and 120 individuals with non-migraine headaches (control group). All individuals were evaluated using the ICHD-II 2004 diagnostic criteria for migraine, as well as the mini-test for PTSD, MMPI (Minnesota Multiphasic Personality Inventory) for psychological evaluation, PAI (Personality Assessment Inventory) and Hamilton Scale for Depression. RESULTS: Among migraine patients, depressive disorders were present in 27.5% of patients, anxiety was found in 60.8%, and PTSD was present in 39.2%. While the prominence of depression was not different between groups, anxiety was significantly more common (p<0.05) in women from the control group. PTSD was significantly more common (p<0.001) in migraine patients overall, whereas the difference in PTSD prevalence between women from the migraine and control groups came close to significance (p=0.05). Females in the migraine group had higher incidences of aura (50% vs. 25.5%), whereas the incidence of aura in males in each group was approximately equal (9.8% vs. 7.84%). CONCLUSION: Based on our data, we can confirm an association between PTSD and migraine in a sample of patients from Kosovo. PMID- 29580568 TI - Giant intradural cervical spine arteriovenous malformations - A case and review of literature. AB - INTRODUCTION: Spinal arteriovenous malformations (SAVMs) are very rare and can be very challenging to treat since none of the therapeutic options does provide a definitive cure to these lesions. We believe that incorporation of intraoperative angiography during surgery in a hybrid theatre can help achieve a better cure. CASE PRESENTATION: We present a 45 years old woman with three (3) years history of weakness and ten (10) days' history of acute pain in right upper extremity. Magnetic resonance angiography (MRA) of the cervical segment of spinal cord revealed tortuous vascular masses from foramen magnum to the inferior margin of fourth cervical (C4) vertebral. Spinal digital subtracting angiography (DSA) confirmed vascular malformation at the cervical segment of the spinal cord with their origin from bilateral posterior spinal arteries. She was successfully operated on with the aid of intraoperative angiography without any neurological deficient. CONCLUSION: Spinal angiography is the gold standard for all-inclusive assessment of SAVMs. Surgery and endovascular techniques equally have key therapeutic valves in treatment of SAVMs but a combination of the two gives a more accurate and reliable cure to this disorder. PMID- 29580569 TI - Default Mode Connectivity in Major Depressive Disorder Measured Up to 10 Days After Ketamine Administration. AB - BACKGROUND: The symptoms of major depressive disorder (MDD) are rapidly alleviated by administration of a single dose of the glutamatergic modulator ketamine. However, few studies have investigated the potential sustained neural effects of this agent beyond immediate infusion. This study used functional magnetic resonance imaging to examine the effect of a single ketamine infusion on the resting state default mode network (DMN) at 2 and 10 days after a single ketamine infusion in unmedicated subjects with MDD as well as healthy control subjects (HCs). METHODS: Data were drawn from a double-blind, placebo-controlled crossover study of 58 participants (33 with MDD and 25 HCs) who received an intravenous infusion of either ketamine hydrochloride (0.5 mg/kg) or placebo on 2 separate test days spaced 2 weeks apart. Eight minutes of functional magnetic resonance imaging resting state data was acquired at baseline and at about 2 and 10 days after both infusions. The DMN was defined using seed-based correlation and was compared across groups and scans. RESULTS: In subjects with MDD, connectivity between the insula and the DMN was normalized compared with HCs 2 days postketamine infusion. This change was reversed after 10 days and did not appear in either of the placebo scans. Group-specific connectivity differences in drug response were observed, most notably in the insula in subjects with MDD and in the thalamus in HCs. CONCLUSIONS: Connectivity changes in the insula in subjects with MDD suggest that ketamine may normalize the interaction between the DMN and salience networks, supporting the triple network dysfunction model of MDD.

PMID- 29580570 TI - Increased Alcohol Seeking in Mice Lacking Gpr88 Involves Dysfunctional Mesocorticolimbic Networks. AB - BACKGOUND: Alcohol use disorder (AUD) is devastating and poorly treated, and innovative targets are actively sought for prevention and treatment. The orphan G protein-coupled receptor GPR88 is enriched in mesocorticolimbic pathways, and Gpr88 knockout mice show hyperactivity and risk-taking behavior, but a potential role for this receptor in drug abuse has not been examined. METHODS: We tested Gpr88 knockout mice for alcohol-drinking and -seeking behaviors. To gain system level understanding of their alcohol endophenotype, we also analyzed whole-brain functional connectivity in naive mice using resting-state functional magnetic resonance imaging. RESULTS: Gpr88 knockout mice showed increased voluntary alcohol drinking at both moderate and excessive levels, with intact alcohol sedation and metabolism. Mutant mice also showed increased operant responding and motivation for alcohol, while food and chocolate operant self-administration were unchanged. Alcohol place conditioning and alcohol-induced dopamine release in the nucleus accumbens were decreased, suggesting reduced alcohol reward in mutant mice that may partly explain enhanced alcohol drinking. Seed-based voxelwise functional connectivity analysis revealed significant remodeling of mesocorticolimbic centers, whose hallmark was predominant weakening of prefrontal cortex, ventral tegmental area, and amygdala connectional patterns. Also, effective connectivity from the ventral tegmental area to the nucleus accumbens and amygdala was reduced. CONCLUSIONS: Gpr88 deletion disrupts executive, reward, and emotional networks in a configuration that reduces alcohol reward and promotes alcohol seeking and drinking. The functional connectivity signature is reminiscent of alterations observed in individuals at risk for AUD. The Gpr88 gene, therefore, may represent a vulnerability/resilience factor for AUD, and a potential drug target for AUD treatment.

AB - The infiltration by numerous osteoclastic giant cells is a frequent finding in bone tumors and pseudo-tumors. Pathologists must integrate clinical and radiological data to achieve a correct diagnosis in bone pathology. Benign giant cell rich lesions of bone encompass giant cell tumor of bone, aneurysmal bone cyst, chondroblastoma, brown tumor and fibrous cortical defect/non-ossifying fibroma. Amongst malignant neoplasms, variants of conventional osteosarcoma, undifferentiated pleomorphic sarcoma, leiomyosarcoma and bone metastasis must be discussed. Recently, new diagnostic markers, antibodies for immuno-histochemistry and genetic markers, have been developed and are helpful to diagnose such lesions.

AB - The prevalence of diabetes is increasing worldwide, with the greatest increases occurring in low- and middle-income countries. In most developed countries, type 2 diabetes is presently the leading cause of end-stage renal disease and also contributes substantially to cardiovascular disease. In countries with weaker economies type 2 diabetes is rapidly replacing communicable diseases as a leading cause of kidney disease and is increasingly competing for scarce health care resources. Here, we present a narrative review of the prevalence and incidence of diabetes-related kidney disease worldwide. Mortality among those with diabetes and kidney disease will also be explored. Given the high morbidity and mortality associated with chronic kidney disease, we will also examine the level of awareness of this disease among people who have it. PMID- 29580577 TI - Competing Risk of Death With End-Stage Renal Disease in Diabetic Kidney Disease. AB - The concept of competing risks is particularly relevant to survival analyses of diabetic ESRD given the high likelihood of death prior to ESRD. Approaches such as Kaplan-Meier curves and Cox regression models operate on the assumption that there are no competing risks for the event of interest, yielding uninterpretable and generally biased estimates in the presence of competing risks. The cumulative incidence function and Fine-Gray regression are more appropriate methodologies for survival analysis when competing risks are present. We present an example taken from the Action to Control Cardiovascular Risk in Diabetes, a randomized trial of people with type 2 diabetes at high risk for cardiovascular disease. Participants were stratified according to baseline markers of kidney disease: (1) no kidney disease; (2) low estimated glomerular filtration rate; (3) microalbuminuria alone; and (4) macroalbuminuria. The macroalbuminuria group had the highest risk for ESRD and demonstrated the most marked difference between the Kaplan-Meier and cumulative incidence estimator. Cox and Fine-Gray regression models yielded similar risk estimates for baseline characteristics, with the exception of diabetes duration, which was significant in the Cox but not Fine Gray model. We underscore the importance of competing risk methods, particularly when the competing risk is common, as is the case in diabetic kidney disease. PMID- 29580578 TI - Glycemic Control as Primary Prevention for Diabetic Kidney Disease. AB - Improving strategies to prevent the development and progression of CKD is a highly desirable outcome for all involved in the care of patients with diabetes. This is because CKD is a major factor contributing to morbidly and mortality in patients with diabetes. Furthermore, diabetes is the leading cause of ESRD in most developed countries. Although tight glucose control is now an established modality for preventing the development and progression of albuminuria, evidence is now accumulating to suggest that it can also ameliorate glomerular filtration rate loss and possibly progression to ESRD. These benefits of intensive glucose control appear to be most pronounced when applied to patients with the early stages of CKD. Recently, medications that belong to the sodium glucose cotransporter-type 2 inhibitor and the glucagon-like peptide-1 receptor analogue classes have been shown to reduce progression of CKD in patients with type 2 diabetes and relatively well-preserved kidney function. Here, we review the evidence from observational and interventional clinical studies that link good glucose control with the primary prevention of diabetic kidney disease with a focus on preventing early glomerular filtration rate loss. PMID- 29580579 TI - New Glucose-Lowering Agents for Diabetic Kidney Disease. AB - The prevalence of diabetes mellitus is increasing and is associated with a range of complications including nephropathy. New antidiabetic agents are sought which also have positive effects to diminish diabetic complications. Examples of promising new classes of such agents are glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, and sodium-glucose cotransporter 2 inhibitors. In addition to cardiovascular protective effects such as weight loss and decreased blood pressure of some of these agents, there is evidence for renoprotective effects with these agents. This review elaborates on the main results of renoprotective effects of these 3 treatment classes. In conclusion, currently available trials have demonstrated renoprotective effects for certain glucagon-like peptide-1 receptor agonists, liraglutide and semaglutide, and the sodium-glucose cotransporter 2 inhibitors, empagliflozin and canagliflozin. Dipeptidyl peptidase-4 inhibitors did not show a significant renoprotective effect. Nevertheless, larger studies with respect to renoprotective effects of these 3 drug classes are currently being performed, and thus, no conclusions for all of these agents can yet be made. PMID- 29580580 TI - Treatment of Diabetic Kidney Disease With Hypertension Control and Renin Angiotensin System Inhibition. AB - The global incidence and prevalence of diabetes continues to expand due primarily to the influences of obesity and the contribution of obesity to the progression of type 2 diabetes mellitus. The rising prevalence of type 2 diabetes has driven an increase in rates of CKD in the past 3 decades in the United States. In turn, so have the rates for complications related to type 2 diabetes including CKD, eg, diabetic kidney disease (DKD). Although incident rates for DKD have stabilized in the recent years, diabetes continues to be the leading cause of ESRD in the United States. The United Kingdom Prospective Diabetes Study data and other population-level studies support that lowering blood pressure reduces kidney disease and cardiovascular disease in patients with type 2 diabetes. Furthermore, strategies targeting renin-angiotensin-aldosterone system interruption have shown to improve DKD outcomes to a greater extent than other classes of antihypertensive regimens. PMID- 29580582 TI - Inflammatory Mechanisms as New Biomarkers and Therapeutic Targets for Diabetic Kidney Disease. AB - Diabetic kidney disease (DKD) is the leading cause of CKD and end-stage kidney disease (ESKD) worldwide. Approximately 30-40% of people with diabetes develop this microvascular complication, placing them at high risk of losing kidney function as well as of cardiovascular events, infections, and death. Current therapies are ineffective for arresting kidney disease progression and mitigating risks of comorbidities and death among patients with DKD. As the global count of people with diabetes will soon exceed 400 million, the need for effective and safe treatment options for complications such as DKD becomes ever more urgent. Recently, the understanding of DKD pathogenesis has evolved to recognize inflammation as a major underlying mechanism of kidney damage. In turn, inflammatory mediators have emerged as potential biomarkers and therapeutic targets for DKD. Phase 2 clinical trials testing inhibitors of monocyte chemotactic protein-1 chemokine C-C motif-ligand 2 and the Janus kinase/signal transducer and activator of transcription pathway, in particular, have produced promising results.

PMID- 29580581 TI - Acute Kidney Injury and Progression of Diabetic Kidney Disease. AB - Diabetic kidney disease, commonly termed diabetic nephropathy (DN), is the most common cause of end-stage kidney disease (ESKD) worldwide. The characteristic histopathology of DN includes glomerular basement membrane thickening, mesangial expansion, nodular glomerular sclerosis, and tubulointerstitial fibrosis. Diabetes is associated with a number of metabolic derangements, such as reactive oxygen species overproduction, hypoxic state, mitochondrial dysfunction, and inflammation. In the past few decades, our knowledge of DN has advanced considerably although much needs to be learned. The traditional paradigm of glomerulus-centered pathophysiology has expanded to the tubule-interstitium, the immune response and inflammation. Biomarkers of proximal tubule injury have been shown to correlate with DN progression, independent of traditional glomerular injury biomarkers such as albuminuria. In this review, we summarize mechanisms of increased susceptibility to acute kidney injury in diabetes mellitus and the roles played by many kidney cell types to facilitate maladaptive responses leading to chronic and end-stage kidney disease. PMID- 29580583 TI - Role of Kidney Biopsies for Biomarker Discovery in Diabetic Kidney Disease. AB - Although estimated glomerular filtration rate and albuminuria are well established biomarkers of diabetic kidney disease (DKD), additional biomarkers are needed, especially for the early stages of the disease when both albuminuria and estimated glomerular filtration rate may still be in the normal range and are less helpful for identifying those at risk of progression. Traditional biomarker studies for early DKD are challenging because of a lack of good early clinical end points, and most rely on changes in existing imprecise biomarkers to assess the value of new biomarkers. There are well-characterized changes in kidney structure, however, that are highly correlated with kidney function, always precede the clinical findings of DKD and, at preclinical stages, predict DKD progression. These structural parameters may thus serve as clinically useful end points for identifying new biomarkers of early DKD. In addition, investigators are analyzing tissue transcriptomic data to identify pathways involved in early DKD which may have associated candidate biomarkers measurable in blood or urine, and differentially expressed microRNAs and epigenetic modifications in kidney tissue are beginning to yield important observations which may be useful in identifying new clinically useful biomarkers. This review examines the emerging literature on the use of kidney tissue in biomarker discovery in DKD. PMID- 29580584 TI - The Promise of Systems Biology for Diabetic Kidney Disease. AB - Diabetic kidney disease (DKD) has a complex and prolonged pathogenesis involving many cell types in the kidney as well as extrarenal factors. It is clinically silent for many years after the onset of diabetes and usually progresses over decades. Given this complexity, a comprehensive and unbiased molecular approach is best suited to help identify the most critical mechanisms responsible for progression of DKD and those most suited for targeted intervention. Systems biological investigations provide such an approach since they examine the entire network of molecular changes that occur in a disease process in a comprehensive way instead of focusing on a single abnormal molecule or pathway. Systems biological studies can also start with analysis of the disease in humans, not in animal or cell culture models that often poorly reproduce the changes in human DKD. Indeed, in the last decade, systems biological approaches have led to the identification of critical molecular abnormalities in DKD and have directly led to development of new biomarkers and potential treatments for DKD. PMID- 29580586 TI - Paediatric bilateral vocal cord paralysis: our experience. AB - : Bilateral vocal cord paralysis (BVCP) is the second most common cause of neonatal stridor. The aim of this study was to describe the demographic features, aetiology, comorbidities, and management of our patients with BVCP. MATERIAL AND METHODS: We conducted a retrospective review of the clinical charts of all patients diagnosed with BVCP seen at the Department of Respiratory Endoscopy between 2011 and 2015. RESULTS: 47 patients were included. Mean age at diagnosis was 1 month and male sex predominated (63%). The aetiology was congenital in 59% and acquired in 41% of the infants. The cause was most frequently idiopathic in the former group and secondary to postoperative injury in the latter. Overall, 42 patients (89%) required tracheostomy, without statistically significant differences between the causes. Of all the patients, 39% regained vocal-cord mobility; 44% of those with congenital BVCP, 31% of those with acquired BVCP and 62.5% with idiopathic BVCP. In five patients a laryngotracheoplasty was performed with a posterior costal cartilage graft and one underwent posterior cordectomy. All were decannulated. In one patient vocal-cord lateralization was performed, avoiding tracheostomy. CONCLUSION: BVCP was most commonly of congenital cause and was mainly idiopathic within this group of patients, with a slight male preponderance. A high percentage of patients required tracheostomy. A higher recovery rate of vocal-cord mobility was observed in idiopathic BVCP, which allowed for successful decannulation. In this series, decannulation was possible in all patients that underwent surgery; however, further studies with comparison of techniques and objective assessment of swallowing and phonation are necessary. PMID- 29580587 TI - Olfactory Disorder Pattern In Patients With Neurological Diseases Excluding Psychiatric And Traumatic Aetiologies. AB - INTRODUCTION: The most common cause of olfactory ENT disorders are colds and flu, chronic sinusitis, allergies and traumatic brain injury. Rarer aetiologies include certain neurological, psychiatric and metabolic injuries. TARGET: The aim of this paper was to check the sort of olfactory disorders found in people who have suffered a brain injury, excluding: cranial traumas, psychiatric diseases, epilepsy, Parkinson's and Alzheimer's disease, and synaesthesia. MATERIAL AND METHODS: A descriptive study based on 61 patients with diagnoses of various neurological injuries, which were tested by BAST-24 olfactometer. The results were compared with those of a control group (n= 120). RESULTS: The results show major impairment in these patients' olfactory sense. The neurological injury patients were able to detect from 60-77% of the odours, while the control group were able to detect between 98-100%. The neurological patients were able, at best, to identify, 11-32% of the odours correctly, while the control group were able to correctly detect between 59 -75%. The differences between odour detection and correct identification were statistically significant (p<.05). CONCLUSIONS: We concluded: a) Neurological injury, not caused by traumatic brain injury, psychiatric disorders or ENT diseases, ranged from 68-89% of the olfactory failures. b) We must bear in mind that these sorts of injuries can cause olfactory disorders. c) ENT and Neurologists should collaborate in the treatment of these disorders.

PMID- 29580590 TI - Decreasing Postanesthesia Care Unit to Floor Transfer Times to Facilitate Short Stay Total Joint Replacements. AB - PURPOSE: We describe a process for studying and improving baseline postanesthesia care unit (PACU)-to-floor transfer times after total joint replacements. DESIGN: Quality improvement project using lean methodology. METHODS: Phase I of the investigational process involved collection of baseline data. Phase II involved developing targeted solutions to improve throughput. Phase III involved measured project sustainability. FINDINGS: Phase I investigations revealed that patients spent an additional 62 minutes waiting in the PACU after being designated ready for transfer. Five to 16 telephone calls were needed between the PACU and the unit to facilitate each patient transfer. The most common reason for delay was unavailability of the unit nurse who was attending to another patient (58%). Phase II interventions resulted in transfer times decreasing to 13 minutes (79% reduction, P < .001). Phase III recorded sustained transfer times at 30 minutes, a net 52% reduction (P < .001) from baseline. CONCLUSIONS: Lean methodology resulted in the immediate decrease of PACU-to-floor transfer times by 79%, with a 52% sustained improvement. Our methods can also be used to improve efficiencies of care at other institutions. PMID- 29580591 TI - A Comparison of Aromatherapy to Standard Care for Relief of PONV and PDNV in Ambulatory Surgical Patients. AB - PURPOSE: To determine effectiveness of aromatherapy (AT) compared with standard care (SC) for postoperative and postdischarge nausea and vomiting (PONV/PDNV) in ambulatory surgical patients. DESIGN: Prospective randomized study. METHODS: Patients (n = 254) received either SC or AT for PONV and interviewed for effectiveness of PDNV. Machine learning methods (eight algorithms) were used to evaluate. FINDING: Of patients (64 of 221) that experienced PONV, 52% were in the AT group and 48% in the SC group. The majority were satisfied with treatment (timely, P = .60; effectiveness, P = .86). Of patients that experienced PDNV, treatment was 100% effective in the AT group and 67% in the SC group. The cforest algorithm was used to develop a model for predicting PONV with literature-based risk factors (0.69 area under the curve). CONCLUSIONS: AT is an effective way to manage PONV/PDNV. Gender and age were the most important predictors of PONV. PMID- 29580592 TI - Benchmarking the Applicability of Four Methods of Endotracheal Tube Cuff Inflation for Optimal Sealing: A Randomized Trial. AB - PURPOSE: To assess the comparable applicability of four methods of endotracheal tube cuff (ETTc) inflation on the basis of optimal level of intracuff pressure and presence of intubation-related complications. DESIGN: Double-blind, randomized trial. METHODS: A total of 139 adult surgical patients scheduled to undergo nitrous oxide-free general anesthesia were assigned into one of four groups according to the method used for ETTc inflation. The cuff pressure and air volume applied in each method, and laryngotracheal complications were recorded. FINDINGS: The highest and lowest ETTc pressure and air volume values were recorded in palpation and minimum leak technique group, respectively. Laryngotracheal complaints were maximized in palpation and minimized in minimal occlusive volume and minimum leak techniques. CONCLUSIONS: The air-return back into the syringe method emerges as an attractive and simple-to-perform alternative regarding effective ETTc sealing and low incidence of intubation related morbidity when a cuff manometer is not readily available.

PMID- 29580593 TI - Multimodal Perioperative Analgesia Regimen to Improve Patient Outcomes After Total Knee Arthroplasty: A Multidisciplinary Quality Improvement Project. AB - PURPOSE: The primary aim of this quality improvement project was to improve mobilization for patients after total knee arthroscopy by developing and implementing a standardized, evidence-based, multimodal analgesia regimen and patient-educational video. Secondary outcomes included opioid consumption, pain, and length of stay. DESIGN: A pre-post implementation design was used to compare two independent samples. METHODS: Patients were screened based on inclusion and exclusion criteria 1-2 weeks before surgery. The anesthesia provider made the final determination for inclusion. Data were collected by retrospective chart review. FINDINGS: Following implementation, patients displayed significantly improved mobilization, reduced opioid consumption, and reduced length of stay. Patient-reported pain scores were similar or significantly lower in the postimplementation group. CONCLUSIONS: Variability of patient outcomes was reduced, and quality of care was improved by standardizing care and incorporating the best available evidence, consistent with organization's resources in the nonacademic-affiliated, community hospital setting. PMID- 29580594 TI - Efficacy of an Ice Popsicle on Thirst Management in the Immediate Postoperative Period: A Randomized Clinical Trial. AB - PURPOSE: Perioperative thirst is an intense discomfort with high incidence in the immediate postoperative period, but nonetheless, it is highly neglected in clinical practice. The purpose of this study was to evaluate the efficacy of an ice popsicle compared with water at room temperature for thirst relief in the immediate postoperative period in terms of variation in the intensity of the initial compared with the final thirst and the satiety reached after an hour of evaluation and intervention. DESIGN: A parallel randomized clinical trial was used. METHODS: A total of 208 patients in the immediate postoperative period were assessed for 1 hour, every 15 minutes. Thirst intensity was assessed initially and subsequently; interventions were performed according to the group: (1) control group, 10 mL of water at room temperature; and (2) experimental group, 10 mL ice popsicle. FINDINGS: The ice popsicle was 37.8% (P < .01) more effective than water regarding the intensity variation between the initial and final thirst. The thirst intensity and number of interventions were different for the two groups as from the second moment (P < .01). Regarding not reaching satiety after an hour of evaluation and intervention, the relative risk was 41%, the relative risk reduction was 59%, the absolute risk reduction was 31%, and the number needed to treat was 3.2. CONCLUSIONS: Ice popsicle has greater efficacy than water at room temperature for thirst management in the immediate postoperative period. PMID- 29580595 TI - Comfort Theory in Practice-Nurse Anesthetists' Comfort Measures and Interventions in a Preoperative Context. AB - PURPOSE: The Comfort Theory proposes a systematic work approach to respond to patients' holistic needs. The usefulness of the Comfort Theory in the perioperative setting should be investigated. The aim of this study was to describe and analyze the nurse anesthetist's comfort measures in the preoperative context on the basis of the Comfort Theory DESIGN: Qualitative observational study METHODS: Semi-structured, clinical observation data collection in the preoperative context and deductive thematic analysis FINDINGS: The nurse anesthetist's comfort measures in the preoperative phase in the operating room department aim to ensure the patient's needs of relief, ease and transcendence in the physical, psycho-spiritual, environmental and socio-cultural contexts CONCLUSIONS: The application of the Comfort Theory to daily work in the preoperative phase is of value for the nurse anesthetist in becoming more aware of the individual holistic needs of the patient and in this way adapting and initiating comfort measures and interventions. PMID- 29580596 TI - A Survey of Perianesthesia Nursing Electronic Documentation. AB - PURPOSE: Electronic health records have become a common part of the perianesthesia care workflow, particularly for data gathering and documentation. The purpose of this survey of perianesthesia nurses was to examine patterns of adoption of electronic health records and their effect on clinical documentation and patient care. DESIGN: A survey was sent to nurses who are members of the American Society of Perianesthesia Nursing (ASPAN). METHODS: The electronic documentation survey was sent to the e-mail addresses of 13,339 ASPAN members representing various practice environments across the United States. Results were examined through descriptive statistics. FINDINGS: About two thirds (66.02%) of the respondents indicated that they could capture 80% of their clinical interactions with the patient. Few nurses indicated that adoption of the EHR was done using a standardized terminology. Respondents (63.99%) overwhelmingly indicated that they spent less time interacting with patients and families because of electronic documentation demands. CONCLUSIONS: The results pertaining to the impact of the EHR on their practice were fairly mixed with some indication that there was greater access to important patient data, but with a trade-off of less satisfaction and efficiency. Improvements and evaluation of clinical documentation are being done, but ongoing optimization and improvements to the EHR based on the knowledge needs of nurses will help realize the promise of greater quality, safety, and access to data. PMID- 29580597 TI - The Quality of Patient Education in Day Surgery by Adult Patients. AB - PURPOSE: The purpose of the study was to describe the quality of patient education in day surgery as evaluated by adult patients. DESIGN: Descriptive design using survey methodology. METHODS: The data were collected by questionnaire and measured the quality and implementation of education resources for day surgery patients (n = 600) in a university hospital. The data were analyzed statistically using basic and multivariate methods. FINDINGS: The implementation of patient education has been done in a patient-centered and goal oriented way by half of respondents. Most respondents (81%) were satisfied with the interaction in patient education. The education resources were reported as good by 77% of respondents. CONCLUSIONS: Health care staff should assess for the presence of anxiety as a barrier to the comprehension of information. In developing patient education, the professional expertise and skills of health care staff in educating patients should be used. PMID- 29580598 TI - Patterns of Changes in Patients' Postoperative Recovery From a Short-Term Perspective. AB - PURPOSE: To explore patterns of changes in patients' postoperative recovery over 1 month within different surgery groups. DESIGN: A quantitative longitudinal survey design was used. METHODS: A standardized questionnaire was used (N = 167 patients); the postoperative recovery profile for self-assessment of recovery. The postoperative recovery profile developed for hospitalized patients contains 17 items distributed over five dimensions: physical symptoms, physical function, psychological function, social function, and activity. FINDINGS: Overall, orthopaedic patients perceived a lower recovery than general surgery patients. All major surgery groups and subgroups except for joint replacement patients indicated significant systematic changes toward lower levels of problems. The orthopaedic patients assessed their psychological functioning as impaired, and the gastric bypass group was the most recovered. CONCLUSIONS: The patients' expectations should be charted initially, and patients should be given realistic information to achieve a realistic hope for a good life in the future. A patient's recovery trajectory may not start after the surgery is completed. Rather, it has already commenced before surgery. PMID- 29580599 TI - Anesthetists and Surgeons Predict Postoperative Pain. AB - PURPOSE: Nurses, surgeons and anesthetists are responsible for the management of postoperative pain. This study aimed to investigate surgeons', surgical residents', anesthesiologists', and anesthetic residents' predictions of patients' postoperative pain and satisfaction with pain management, compared to patients' postoperative ratings. DESIGN: The bias and limits of agreement between physician and patient ratings of postoperative pain were compared. METHODS: Doctors and patients completed a pain questionnaire (Numeric Rating Scale 11 point) regarding patients' overall pain, worst pain, and dissatisfaction with pain management during the first three days postoperatively. FINDINGS: All doctors overestimated the degree of pain. Possible reasons include the efforts of the postoperative multidisciplinary team. Surgeons were the most accurate regarding patients' worst pain. The limits of agreement for doctor and patient ratings were very wide. CONCLUSIONS: Postoperative pain management is better than predicted. PMID- 29580600 TI - Globalization of Health Service: Sharing of Best Practices in Perianesthesia Nursing Care, a Case Study of Cross-Border Institutional Collaboration. AB - Healthcare is a global concern among all nations and nursing is a global profession as evidenced by the flow of healthcare professionals across international boundaries. With English as the language of science and commerce and post-colonial influence in domestic healthcare practice and training, many former Anglo-speaking colonial settlements become parts of an expansive market for health human resources migration. The movement of health personnel mainly flows from low and medium income countries to high income countries to sustain their health systems. The resulting brain drain adversely impacts a source country's health system, leading the World Health Organization to declare global health migration as the biggest health threat of the 21st century. This report illustrates how an overseas health network achieves its goals of developing clinical and management excellence through an international exchange program. The provider institution also fulfills its mission of contributing to a more balanced, equitable and healthier world. PMID- 29580601 TI - Effective Communication Improves Patient Safety.

However, uncertainty exists about the extent to which the major social determinants of mental disorders are addressed by these goals. The aim of this study was to develop a conceptual framework for the social determinants of mental disorders that is aligned with the Sustainable Development Goals, to use this framework to systematically review evidence regarding these social determinants, and to identify potential mechanisms and targets for interventions. We did a systematic review of reviews using a conceptual framework comprising demographic, economic, neighbourhood, environmental events, and social and culture domains. We included 289 articles in the final Review. This study sheds new light on how the Sustainable Development Goals are relevant for addressing the social determinants of mental disorders, and how these goals could be optimised to prevent mental disorders.

AB - The European pediatric regulation, that entered into force in June 2007 with the objectives to improve the health of children in Europe, dramatically changed the regulatory environment of paediatric drug evaluation in Europe. The recent 10years European medicines agency (EMA) report showed that the number of paediatric trials increased and that 238 new medicines and indications for use in children were authorised in the EU. However, results remain constrated and futur developments require european collaborations beween all experts in developmental pharmacology, drug evaluation and trial conduct, training, all aspects already considered in different EU paediatric programs. PMID- 29580613 TI - Pharmacoepidemiology in pediatrics: Needs, challenges and future directions for research. AB - Despite international initiatives to promote clinical research in pediatrics, there are still many gaps of knowledge in the use of drugs to treat this specific population. When important information cannot be derived only from clinical trials, use of available observational research tools is required. In this paper, we provide an overview of the particular interest of pharmacoepidemiological research into the evaluation of drug effects in children and adolescents. We also sought to underline the unique challenges and specific needs regarding this research. Implementation of innovative methodologies and expansion of database networks to perform necessary studies could further improve performances of observational research. PMID- 29580614 TI - Off-label and unlicensed drug use in children population. AB - INTRODUCTION: Off-label (OL) and unlicensed (UL) drug use is widely developed in the pediatric population according to previous reviews published in the early 2010s. The present study is a narrative review of the literature of OL-UL drug use from 2013. METHODS: We performed a literature search of research articles assessing OL-UL drug use in children (<18 years-old) published in Medline(r) from January 2013 until May 2017. RESULTS: Twenty-seven studies were included. OL drug use was defined by inappropriate age, indication, dosage or way of administration according to the summary of product characteristics in >80% of studies. UL drug used was defined by the use of drugs not licensed in the country or modifications of licensed drugs in >70% of studies. Among in- and out-patients, the frequency of patients exposed to at least one OL-UL drug ranged from 36.3 to 97.0% and from 18.6 to 40.2%, respectively. Drug use was categorized as OL mostly due to inappropriate age, dosage or indication. OL-UL drug use was the most prevalent in newborns (mainly preterms) and pre-school children (aged 2-5years). Various drugs were involved, depending on patients' age. Polypharmacy and long hospital stays were risk factors for OL-UL drug use. Whether OL-UL drug use leads to a higher incidence of adverse drug reactions is a controversial finding. CONCLUSIONS: OL UL drug use is frequent in children. A standardized definition of OL-UL drug use is needed to better assess its frequency, risk factors and impact. PMID- 29580616 TI - Increasing robustness of radial GRASE acquisition for SAR-reduced brain imaging. AB - PURPOSE: To improve a radial multi-slice 2D gradient- and spin-echo (GRASE) sequence and provide an appropriate image reconstruction technique for SAR reduced high-resolution neuroimaging. METHODS: Additional readout gradients per radio-frequency (RF) refocusing allow for a reduced number of RF pulses. In this way, a specific absorption rate (SAR) reduction is achieved and the application at high-field systems becomes more feasible. A phase insensitive image reconstruction is proposed to reduce signal dropout artifacts originating from opposite readout polarities. In addition, the image reconstruction allows for the calculation of images with varying contrast from one measurement. RESULTS: Results obtained at 3T and 7T demonstrate a SAR-reduction of at least 66% for a single-slice experiment with radial GRASE. The reduced SAR is used for an increased spatial coverage without increasing the measurement time. Experiments at 3T and 7T showed that the visual image quality is comparable to standard TSE and GRASE sequences with the same measurement parameters. Using higher EPI factors and the presented image reconstruction, artifact-free images with a significant SAR-reduction can be achieved. CONCLUSION: Radial GRASE enables SAR reduced acquisitions of high-resolution brain images with different contrasts from one measurement and is a promising sequence for high-field neuroimaging. PMID- 29580615 TI - [SaO2 and PaO2 mismatch: Do not forget hemoglobinopathy]. AB - INTRODUCTION: Different clinico-biological parameters are used to estimate the amount of oxygen available for the organism. Oxygen saturation measured with pulse oxymetry (SpO2), oxygen saturation of arterial blood (SaO2) and oxygen partial pressure of the arterial blood (PaO2) are the most commonly used. CASE REPORT: We report the case of a patient admitted for investigation of respiratory failure in the context of chronic dyspnea of effort. SpO2 and SaO2 were decreased, though the PaO2 was normal. This mismatch between oxygen saturation and PaO2 led to the diagnosis of hemoglobinopathy (Bassett hemoglobin). CONCLUSION: The diagnosis of hemoglobinopathy should be considered in cases of oxygen desaturation with normal respiratory and cardiac investigations. There are no reasons to prescribe long-term oxygen to these patients. PMID- 29580617 TI - Biocontrol activity of surfactin A purified from Bacillus NH-100 and NH-217 against rice bakanae disease. AB - The potential of the Bacillus genus to antagonize phytopathogens is associated with the production of cyclic lipopeptides. Depending upon the type of lipopeptide, they may serve as biocontrol agents that are eco-friendly alternatives to chemical fertilizers. This study evaluates the biocontrol activity of surfactin-producing Bacillus (SPB) strains NH-100 and NH-217 and purified surfactin A from these strains against rice bakanae disease. Biologically active surfactin fractions were purified by HPLC, and surfactin A variants with chain lengths from C12 to C16 were confirmed by LCMS-ESI. In hemolytic assays, a positive correlation between surfactin A production and halo zone formation was observed. The purified surfactin A had strong antifungal activity against Fusarium oxysporum, F. moniliforme, F. solani, Trichoderma atroviride and T. reesei. Maximum fungal growth suppression (84%) was recorded at 2000 ppm against F. moniliforme. Surfactin A retained antifungal activity at different pH levels (5-9) and temperatures (20, 50 and 121 degrees C). Hydroponic and pot experiments were conducted to determine the biocontrol activity of SPB strains and the purified surfactin A from these strains on Super Basmati rice. Surfactin production in the rice rhizosphere was detected by LCMS ESI at early growth stages in hydroponics experiments inoculated with SPB strains. However, the maximum yield was observed with a consortium of SPB strains (T4) and purified surfactin A (T5) treatments in the pot experiment. The outcomes of the present study revealed that surfactin A significantly reduced rice bakanae disease by up to 80%. These findings suggest that purified surfactin A could be an effective biocontrol agent against bakanae disease in rice and should be incorporated into strategies for disease management.

AB - Corynebacterium glutamicum can degrade phenol by a meta-cleavage pathway, which depends on ncgl2588 (phe) of the phe operon encoding phenol hydroxylase. An additional gene, ncgl2587 (pheR), is located upstream of phe. The pheR encodes an AraC/XylR-type regulator protein with 377 amino acid residues and is transcribed in the same direction as phe. Disruption of pheR by homologous recombination resulted in the accumulation of phenol in C. glutamicum. PheR demonstrates a low type of constitutive expression where phenol induces phe expression. PheR shares 75% sequence identity with AraC-type regulator of Corynebacterium lubricantis and 37 conserved residues, characteristic of AraC family, were located. A constructed pK18mobsacB-Pphe:lacZ transcriptional fusion plasmid was transformed into the wild-type, DeltapheR, and DeltapheR+ strains, and the results indicated that PheR activates the expression of phe encoding phenol hydroxylase. Electrophoretic mobility shift assay (EMSA) demonstrated a direct interaction of PheR with the phe promoter region and binding site of PheR on the Pphe was located 109-bp upstream of phe, as indicated by foot printing analysis. Our research provides deep insight into PheR expression and its regulatory function on Phe in C. glutamicum. PMID- 29580619 TI - Plant growth promoting bacteria as an alternative strategy for salt tolerance in plants: A review. AB - Approximately 5.2 billion hectare agriculture land are affected by erosion, salinity and soil degradation. Salinity stress has significantly affecting the fertile lands, and therefore possesses a huge impact on the agriculture and economy of a country. Salt stress has severe effects on the growth and development of plants as well as reducing its yield. Plants are inherently equipped with stress tolerance ability to responds the specific type of stress. Plants retained specific mechanisms for salt stress mitigation, such as hormonal stimulation, ion exchange, antioxidant enzymes and activation of signaling cascades on their metabolic and genetic frontiers that sooth the stressed condition. Additional to the plant inherent mechanisms, certain plant growth promoting bacteria (PGPB) also have specialized mechanism that play key role for salt stress tolerance and plant growth promotion. These bacteria triggers plants to produce different plant growth hormones like auxin, cytokinine and gibberellin as well as volatile organic compounds. These bacteria also produces growth regulators like siderophore, which fix nitrogen, solubilize organic and inorganic phosphate. Considering the importance of PGPB in compensation of salt tolerance in plants, the present study has reviewed the different aspect and mechanism of bacteria that play key role in promoting plants growth and yield. It can be concluded that PGPB can be used as a cost effective and economical tool for salinity tolerance and growth promotion in plants. PMID- 29580620 TI - Physiologically distinct subpopulations formed in Escherichia coli cultures in response to heat shock. AB - Bacteria can form heterogeneous populations containing phenotypic variants of genetically identical cells. The heterogeneity of populations can be considered a bet-hedging strategy allowing adaptation to unknown environmental changes - at least some individual subpopulations or cells might be able to withstand future adverse conditions. Using Percoll gradient centrifugation, we demonstrated that in an Escherichia coli culture exposed to heat shock at 50 degrees C, two physiologically distinct subpopulations were formed. A high-density subpopulation (HD50) demonstrated continued growth immediately after its transfer to LB medium, whereas the growth of a low-density subpopulation (LD50) was considerably postponed. The LD50 subpopulation contained mainly viable but non-culturable bacteria and exhibited higher tolerance to sublethal concentrations of antibiotics or H2O2 than HD50 cells. The levels of aggregated proteins and main molecular chaperones were comparable in both subpopulations; however, a decreased number of ribosomes and a significant increase in protein oxidation were observed in the LD50 subpopulation as compared with the HD50 subpopulation. Interestingly, under anaerobic heat stress, the formation of the HD50 subpopulation was decreased and culturability of the LD50 subpopulation was significantly increased. In both subpopulations the level of protein aggregates formed under anaerobic and aerobic heat stress was comparable. We concluded that the formation of protein aggregates was independent of oxidative damage induced by heat stress, and that oxidative stress and not protein aggregation limited growth and caused loss of LD50 culturability. Our results indicate that heat stress induces the formation of distinct subpopulations differing in their ability to grow under standard and stress conditions. PMID- 29580621 TI - Heat stress-induced reactive oxygen species participate in the regulation of HSP expression, hyphal branching and ganoderic acid biosynthesis in Ganoderma lucidum. AB - Heat stress (HS) is an important environmental factor that affects the growth and metabolism of edible fungi, but the molecular mechanism of the heat stress response (HSR) remains unclear. We previously reported that HS treatment increased the length between two hyphal branches and induced the accumulation of ganoderic acid biosynthesis and the gene expression of heat shock proteins (HSPs) in Ganoderma lucidum. In this study, we found that HS induced a significant increase in the cytosolic ROS concentration, and exogenously added ROS scavengers NAC, VC and NADPH oxidase (Nox) inhibitor DPI reduce the cytosolic ROS accumulation in G. lucidum. In addition, the phenomena of the increased gene expression and increased length between the two hyphal branches and the accumulation of GA biosynthesis induced by HS were mitigated. Furthermore, we investigated the effects of HS on Nox-silenced strains (NoxABi-10, NoxABi-11 and NoxRi-4, NoxRi-7) and found that the level of ROS concentration was lower than that in wild-type (WT) strains treated with HS. Additionally, Nox silenced strains reduced the HS-induced increase in HSP expression, the length between two hyphal branches and GA biosynthesis compared with the WT strain. These data indicate that HS-induced ROS participate in the regulation of HSP expression, hyphal branching and ganoderic acid biosynthesis in G. lucidum. In addition, these findings identified potential pathways linking ROS networks to HSR, physiological and metabolic processes in fungi and provide a valuable reference for studying the role of ROS in HSR, mycelium growth and secondary metabolites. PMID- 29580622 TI - Phospholipases play multiple cellular roles including growth, stress tolerance, sexual development, and virulence in fungi. AB - Phospholipases are ubiquitous enzymes that hydrolyze phospholipids. Based on the cleavage site of the ester linkage in the substrate phospholipids, phospholipases are classified into four major types, phospholipase A (PLA), phospholipase B (PLB), phospholipase C (PLC), and phospholipase D (PLD), which are further classified into various subtypes. Phospholipases hydrolyze phospholipids into various signaling products including phosphatidic acid (PA), diacylglycerol (DAG), free fatty acids (FFAs), and lyso-phospholipids (LPLs). These signaling products regulate numerous processes such as cytoskeletal dynamics, growth, homeostasis, membrane remodeling, nutrient acquisition, secretion, signal transduction, stress tolerance, sexual development, and virulence in various organisms including fungi. Due to these key cellular roles, phospholipases are also promising targets in diagnostic and therapeutic applications. In this review, we discuss current knowledge about the cellular roles of different classes of phospholipases in fungi. PMID- 29580623 TI - Phosphorylation of PppA at threonine 253 controls T6SS2 expression and bacterial killing capacity in the marine pathogen Vibrio alginolyticus. AB - Type VI secretion systems (T6SSs) are multi-protein secretory nano-machines that mediate inter-bacterial competition. Vibrio alginolyticus is an abundant gram negative marine bacterium that efficiently kills other bacteria with its T6SS2. The V. alginolyticus T6SS2 gene cluster encodes a phosphatase, PppA, and a type II membrane-spanning Hanks-type threonine kinase, PpkA2, which have been implicated in the activation of T6S. Meanwhile, T6SS2 gene expression is under the control of quorum sensing. However, the role of PppA in T6SS2 activity is unclear. Here, our phosphoproteomic screen identified PppA as a novel PpkA2 substrate. Phosphorylation at threonine 253 (T253) of PppA is not conserved in other bacteria, suggesting that PppA may play a unique role in T6SS2 activation in V. alginolyticus. Interestingly, PppA phosphatase activity was modulated by the cognate kinase PpkA2, which implied that a homeostasis is required for optimal T6S activity. PppA and phosphorylation of PppA at T253 are important for T6S activity and T6SS2-mediated bacterial killing. Moreover, PppA and the phosphorylation of PppA are also essential for the expression of LuxR, the master regulator of quorum sensing, thus augmenting T6SS2 expression. Collectively, our data demonstrated that phosphorylation of PppA at T253 controls the activity of T6SS2, thereby enhancing the competitive fitness of V. alginolyticus. PMID- 29580624 TI - Antidiabetic "gliptins" affect biofilm formation by Streptococcus mutans. AB - Streptococcus mutans, a dental caries causing odontopathogen, produces X-prolyl dipeptidyl peptidase (Sm-XPDAP, encoded by pepX), a serine protease known to have a nutritional role. Considering the potential of proteases as therapeutic targets in pathogens, this study was primarily aimed at investigating the role of Sm XPDAP in contributing to virulence-related traits. Dipeptidyl peptidase (DPP IV), an XPDAP analogous enzyme found in mammalian tissues,is a well known therapeutic target in Type II diabetes. Based on the hypothesis that gliptins, commonly used as anti-human-DPP IV drugs, may affect bacterial growth upon inhibition of Sm XPDAP, we have determined their ex vivo antimicrobial and anti-biofilm activity towards S. mutans. All three DPP IV drugs tested reduced biofilm formation as determined by crystal violet staining. To link the observed biofilm inhibition to the human-DPP IV analogue present in S. mutans UA159, a pepX isogenic mutant was generated. In addition to reduced biofilm formation, CLSM studies of the biofilm formed by the pepX isogenic mutant showed these were comparable to those formed in the presence of saxagliptin, suggesting a probable role of this enzyme in biofilm formation by S. mutans UA159. The effects of both pepX deletion and DPP IV drugs on the proteome were studied using LC-MS/MS. Overall, this study highlights the potential of Sm-XPDAP as a novel anti-biofilm target and suggests a template molecule to synthesize lead compounds effective against this enzyme. PMID- 29580625 TI - Letter to the Editor: Public Health Nursing. PMID- 29580626 TI - Reprint of: A chemical screen identifies trifluoperazine as an inhibitor of glioblastoma growth. AB - Glioblastoma (GBM) is regarded as the most common malignant brain tumor but treatment options are limited. Thus, there is an unmet clinical need for compounds and corresponding targets that could inhibit GBM growth. We screened a library of 80 dopaminergic ligands with the aim of identifying compounds capable of inhibiting GBM cell line proliferation and survival. Out of 45 active compounds, 8 were further validated. We found that the dopamine receptor D2 antagonist trifluoperazine 2HCl inhibits growth and proliferation of GBM cells in a dose dependent manner. Trifluoperazine's inhibition of GBM cells is cell line dependent and correlates with variations in dopamine receptor expression profile. We conclude that components of the dopamine receptor signaling pathways are potential targets for pharmacological interventions of GBM growth. PMID- 29580628 TI - Prognostic Usefulness of Tricuspid Annular Diameter for Cardiovascular Events in Patients With Tricuspid Regurgitation of Moderate to Severe Degree. AB - Functional tricuspid regurgitation (TR) is frequently encountered. Current guidelines recommend the surgical correction of severe TR only at the time of left valve surgery despite emphasizing the enlarged tricuspid annulus (TA) dimension. We attempted to evaluate the relation between TA dimension and clinical outcomes of moderate or severe TR. A total of 213 patients (mean age 68 years, women 68%) with moderate or severe TR secondary to left-sided valve surgery, nonvalvular disease, or isolated primary TR were retrospectively identified and classified into tertiles of TA dimension. Cardiovascular (CV) outcomes were defined as a composite of hospitalization for worsening heart failure (HF), stroke, and CV death over a median follow-up of 3.4 years. Upper and lower tertiles of TA dimension had high frequencies of left-sided valve surgery and isolated primary TR, respectively. TA dimension was correlated with TR severity assigned as color Doppler grade and systolic tissue Doppler imaging of the tricuspid valve (TDI s'). During follow-up, there were 87 (41%) occurrences of primary outcomes: 65 HFs (31%), 13 CV deaths (6%), and 9 strokes (4%). There was a high frequency of adverse outcomes in the upper tertile. TA dimension and TDI s' were independently related to outcomes. An enlarged TA dimension was associated with outcomes irrespective of subgroups according to type or severity of TR and TDI s' (p = 0.21, p = 0.77, p = 0.15 for interaction). A cut-off value of 4.0 cm for TA dimension was best for CV event occurrence. When assessing clinical CV outcomes, TA dimension should be considered, even in moderate TR. PMID- 29580629 TI - Rates of Echocardiography, Coronary Angiography, and Coronary Intervention Associated With Troponin Testing in Hospitalized Patients. AB - Diagnosis of acute myocardial infarction (AMI) often depends on detection of cardiac troponin elevation >99th percentile. However, troponin elevation is commonly found in patients without AMI. We have previously reported an association between troponin elevation and rates of electrocardiogram (ECG), echocardiography (ECHO), and coronary angiography (CAG) in patients with a primary diagnosis of sepsis. We hypothesized that elevated troponin might be associated with greater use of ECHO and CAG in primary diagnoses other than sepsis and that this correlation might also include percutaneous coronary intervention (PCI). We reviewed all inpatient admissions to nine hospitals in Texas in 2016 collecting primary International Statistical Classification of Diseases and Related Health Problems (International Classification of Diseases 10) diagnoses, troponin test data, and the presence of ECHO, CAG, or PCI during hospitalization. We identified 56,895 unique inpatient admissions, of which 14,326 (25.2%) were associated with troponin testing. Of patients tested, 26.1% had one or more troponin I values >=0.1 ng/ml (99th percentile). Primary ICD-10 diagnoses were grouped into (1) AMI, (2) primary diagnosis other than AMI (non AMI), (3) congestive heart failure (CHF), (4) sepsis, and (5) Other excluding AMI, CHF, or sepsis. Troponin testing was itself associated with greater utilization of ECHO, CAG, and PCI in all groups except CHF. Troponin I values >=0.1 ng/ml were associated with increased rates of ECHO, CAG, and PCI across all groups. PMID- 29580627 TI - Alcohol Consumption and Risk of Coronary Artery Disease (from the Million Veteran Program). AB - Moderate alcohol consumption has been associated with a lower risk of coronary artery disease (CAD) in the general population but has not been well studied in US veterans. We obtained self-reported alcohol consumption from Million Veteran Program participants. Using electronic health records, CAD events were defined as 1 inpatient or 2 outpatient diagnosis codes for CAD, or 1 code for a coronary procedure. We excluded participants with prevalent CAD (n = 69,995) or incomplete alcohol information (n = 8,449). We used a Cox proportional hazards model to estimate hazard ratios and 95% confidence intervals for CAD, adjusting for age, gender, body mass index, race, smoking, education, and exercise. Among 156,728 participants, the mean age was 65.3 years (standard deviation = 12.1) and 91% were men. There were 6,153 CAD events during a mean follow-up of 2.9 years. Adjusted hazard ratios (95% confidence intervals) for CAD were 1.00 (reference), 1.02 (0.92 to 1.13), 0.83 (0.74 to 0.93), 0.77 (0.67 to 0.87), 0.71 (0.62 to 0.81), 0.62 (0.51 to 0.76), 0.58 (0.46 to 0.74), and 0.95 (0.85 to 1.06) for categories of never drinker; former drinker; current drinkers of <=0.5 drink/day, >0.5 to 1 drink/day, >1 to 2 drinks/day, >2 to 3 drinks/day, and >3 to 4 drinks/day; and heavy drinkers (>4 drinks/day) or alcohol use disorder, respectively. For a fixed amount of ethanol, intake at >=3 days/week was associated with lower CAD risk compared with <=1 day/week. Beverage preference (beer, wine, or liquor) did not influence the alcohol-CAD relation. Our data show a lower risk of CAD with light-to-moderate alcohol consumption among US veterans, and drinking frequency may provide a further reduction in risk. PMID- 29580630 TI - Feasibility of Performing Radiofrequency Catheter Ablation and Endomyocardial Biopsy in the Same Setting. AB - In patients with unexplained cardiomyopathy, electroanatomical mapping can identify abnormal tissue to target during electrophysiology-guided endomyocardial biopsy (EP-guided EMB). The objective of this study is to determine whether catheter ablation performed in the same setting as EP-guided EMB increases procedural risk. Sixty-seven patients (mean age 54.4 +/- 13.8, 57% male) undergoing EP-guided EMB were included. Radiofrequency catheter ablation was performed in 17 patients (25%) for ventricular arrhythmias and in 2 (3%) for typical atrial flutter. Femoral arterial access was obtained in 90% ablation patients and 40% biopsy-only patients; vascular access complications were more common in the ablation group than in the EMB-only group (p = 0.02). There were no significant differences in rate of tricuspid regurgitation, thromboembolism, or pericardial effusion, whether procedural anticoagulation was used. In conclusion, catheter ablation and procedural anticoagulation can be combined with EP-guided EMB with an increased risk of vascular access complications, but no significant increase in intracardiac complications. PMID- 29580631 TI - Predictors of Left Ventricular Remodeling After Myocardial Infarction in Patients With a Patent Infarct Related Coronary Artery After Percutaneous Coronary Intervention (from the Post-Myocardial Infarction Remodeling Prevention Therapy [PRomPT] Trial). AB - Left ventricular (LV) remodeling after myocardial infarction (MI) is a strong predictor of heart failure and mortality. The predictors of long-term remodeling after MI have been incompletely studied. We therefore examined the correlates of LV remodeling in patients with large ST-segment elevation myocardial infarction and a patent infarct artery after percutaneous 2coronary intervention (PCI) from the randomized Post-Myocardial Infarction Remodeling Prevention Therapy trial. Peri-infarct pacing had a neutral effect on long-term remodeling in patients with large first MI. The present analysis includes 109 patients in whom an open artery was restored after PCI, and in whom LV end-diastolic volume (LVEDV) at baseline and 18 months was assessed by transthoracic echocardiography. Multivariable models were fit to identify the independent predictors of LVEDV at baseline and 18 months. By multivariable analysis, male sex (p = 0.004) and anterior MI location (p = 0.03) were independently associated with baseline LVEDV. The following variables were independent predictors of increased LVEDV at 18 months: younger age (p = 0.01), male sex (p = 0.03), peak creatine phosphokinase (p = 0.03), shorter time from MI to baseline transthoracic echocardiography (p = 0.04), baseline LVEDV (p < 0.0001), and lack of statin use (p = 0.03). In conclusion, patients with large MI and an open infarct artery after PCI, anterior MI location, and male sex were associated with greater baseline LVEDV, but MI location was not associated with 18-month LVEDV. In contrast, younger age, peak creatine phosphokinase, male sex, baseline LVEDV, and lack of statin use were associated with long-term LV remodeling. PMID- 29580632 TI - Relation of Blood Pressure to Severity of Pericardial Effusion. AB - Subacute tamponade is a challenging diagnosis requiring careful consideration of both clinical and imaging data. We aimed at exploring the association of initial blood pressure with markers of pericardial effusion severity in patients with moderate and large pericardial effusion. We conducted a retrospective, single center study in 102 well-phenotyped patients with moderate and large pericardial effusion. The presenting systolic and diastolic blood pressure recordings were divided into tertiles to examine the association between the blood pressure and the different established markers of pericardial effusion severity. On presentation, 42% of patients had systolic blood pressure exceeding 130 mm Hg, and only 5% of patients had systolic blood pressure <90 mm Hg. Patients in the lowest blood pressure tertiles did not differ significantly from patients in the upper tertiles in terms of clinical, etiologic, or echocardiographic characteristics. Although patients who underwent pericardial drainage had higher presenting heart rates, no significant differences were seen in the blood pressure recordings, either systolic or diastolic (mean 125 mm Hg vs 130 mm Hg, p = 0.36 and 76 vs 75 mm Hg, p = 0.82, respectively). In conclusion, systolic and diastolic blood pressure recordings upon initial presentation do not demonstrate a significant association with markers of effusion severity or the need for drainage in patients with moderate and large pericardial effusion. PMID- 29580633 TI - Relation of Testosterone Levels to Mortality in Men With Heart Failure. AB - We aimed to investigate the impact of testosterone on the prognosis of heart failure (HF), as well as the underlying cardiac function, cardiac damage, and exercise capacity. We analyzed consecutive 618 men with HF (age 65.9 years). These patients were divided into quartiles based on their serum levels of total testosterone (TT): first (TT > 631 ng/dl, n = 154), second (462 < TT <= 631 ng/dl, n = 155), third (300 < TT <= 462 ng/dl, n = 156), and fourth (TT <= 300 ng/dl, n = 153) quartiles. In the Kaplan-Meier analysis (mean 1,281 days), all cause mortality progressively increased throughout from the first to the fourth groups. In the multivariable Cox proportional hazard analysis, TT was found to be an independent predictor of all-cause mortality (hazard ratio 0.929, p = 0.042). In addition, we compared the parameters of echocardiography and cardiopulmonary exercise testing, as well as levels of B-type natriuretic peptide and cardiac troponin I, among the 4 groups. Left ventricular ejection fraction and B-type natriuretic peptide did not differ among the groups. In contrast, the fourth quartile, compared with the first, second, and third groups, had higher levels of troponin I and lower peak VO2 (p <0.05, respectively). Decreased serum testosterone is associated with myocardial damage, lower exercise capacity, and higher mortality in men with HF. PMID- 29580634 TI - The relationship between posttraumatic and depressive symptoms during virtual reality exposure therapy with a cognitive enhancer. AB - Two studies suggest that reductions in posttraumatic symptoms (Aderka et al., 2013) and cognitions (Zalta et al., 2014) precede reductions in depressive symptoms during prolonged exposure (PE) therapy for posttraumatic stress disorder (PTSD) in female assault survivors. The present study explored the temporal relationship between posttraumatic and depressive symptoms in a randomized trial of D-Cycloserine (DCS) versus placebo augmented virtual reality exposure (VRE) therapy for chronic World Trade Center-related PTSD following the September 11, 2001 terrorist attacks. Twenty-five male and female participants were randomly assigned to receive either 100 mg DCS (N = 13) or placebo (N = 12) 90 min before 12 weekly VRE sessions. Participants contributed a total of 280 weekly PTSD Checklist (PCL; Weathers et al., 1993) and Beck Depression Inventory-second edition (BDI-II; Beck et al., 1996) symptom scores. Two sets of mediation analyses for longitudinal mixed models assessed the effects of 1) lagged PCL on BDI-II (Model 1), and 2) lagged BDI-II on PCL (Model 2) in the VRE-DCS and VRE Placebo treatment groups, respectively. Results revealed reciprocal relations between posttraumatic and depressive symptoms during VRE treatment, although reductions in posttraumatic symptoms led to subsequent reductions in depressive symptoms to a greater extent than the converse. These effects were stronger in the DCS-enhanced group. Findings suggest that VRE primarily decreases posttraumatic symptoms, which in turn leads to decreased depressive symptoms, and that DCS may strengthen these effects. PMID- 29580635 TI - Prevention and treatment of hyperphosphatemia in chronic kidney disease. AB - Hyperphosphatemia has consistently been shown to be associated with dismal outcome in a wide variety of populations, particularly in chronic kidney disease (CKD). Compelling evidence from basic and animal studies elucidated a range of mechanisms by which phosphate may exert its pathological effects and motivated interventions to treat hyperphosphatemia. These interventions consisted of dietary modifications and phosphate binders. However, the beneficial effects of these treatment methods on hard clinical outcomes have not been convincingly demonstrated in prospective clinical trials. In addition, exposure to high amounts of dietary phosphate may exert untoward actions even in the absence of overt hyperphosphatemia. Based on this concept, it has been proposed that the same interventions used in CKD patients with normal phosphate concentrations be used in the presence of hyperphosphatemia to prevent rise of phosphate concentration and as an early intervention for cardiovascular risk. This review describes conceptual models of phosphate toxicity, summarizes the evidence base for treatment and prevention of hyperphosphatemia, and identifies important knowledge gaps in the field. PMID- 29580636 TI - Pyrophosphate deficiency in vascular calcification. AB - Pathologic cardiovascular calcification is associated with a number of conditions and is a common complication of chronic kidney disease. Because ambient calcium and phosphate levels together with properties of the vascular matrix favor calcification even under normal conditions, endogenous inhibitors such as pyrophosphate play a key role in prevention. Genetic diseases and animal models have elucidated the metabolism of extracellular pyrophosphate and demonstrated the importance of pyrophosphate deficiency in vascular calcification. Therapies based on pyrophosphate metabolism have been effective in animal models, including renal failure, and hold promise as future therapies to prevent vascular calcification. PMID- 29580638 TI - The effectiveness of influenza vaccination among nursery school children in China during the 2016/17 influenza season. AB - BACKGROUND: The effectiveness of influenza vaccine among nursery school children has not been systematically studied. We conducted a cohort study of children from 13 nursery schools in Suzhou, China, to estimate the effectiveness of influenza vaccine against laboratory-confirmed influenza during 2016-17. METHODS: Children aged 36-72 months were chosen from 13 nursery schools from 3 District in Suzhou. The surveillance started 2 weeks after vaccination during October 2016-February 2017. Class teachers reported the names of students with ILI (influenza-like illness) to study clinicians on each school day. Further, local physicians collected the student's nasopharyngeal swab or throat swab, either at a study clinic or at the child's home. The swabs were sent to the National Influenza Network Laboratory in Suzhou Center for Disease Control and Prevention for influenza testing by RT-PCR. RESULT: A total of 4614 children were enrolled, of which 15 children (vaccinated: 2; unvaccinated: 13) were lost to follow-up. Of the remaining 4599 children, 558 swabs were collected. Among these swabs, 70 samples tested positive for influenza virus; 17 in the vaccinated group (B Victoria: 2; H3N2: 15) and 53 in the unvaccinated group (B Victoria: 14; A(H1N1)pdm09: 1; H3N2: 38). The overall influenza vaccine effectiveness (VE) during the influenza season of 2016-2017 was 20.6%. The incidence of developing ILI symptoms and healthcare seeking behavior through clinical visits was significantly lower in vaccinated children than in the unvaccinated group. CONCLUSION: Influenza vaccine protection in vaccinated and unvaccinated children showed no statistical difference and the VE percentage varied for different virus subtypes. However, the incidence rate of developing ILI and healthcare seeking behavior was significant lower in the vaccinated group than in the unvaccinated children. Larger studies are required to estimate the VE according to the influenza type, subtype, and lineage during influenza seasons in China in the future. PMID- 29580637 TI - Detection of renin lineage cell transdifferentiation to podocytes in the kidney glomerulus with dual lineage tracing. AB - Understanding of cellular transdifferentiation is limited by the technical inability to track multiple lineages in vivo. To overcome this we developed a new tool to simultaneously fate map two distinct cell types in the kidney, and genetically test whether cells of renin lineage (CoRL) can transdifferentiate to a podocyte fate. Ren1cCreER/tdTomato/Nphs1-FLPo/FRT-EGFP mice (CoRL-PODO mice) were generated by crossing Ren1c-CreER/tdTomato CoRL reporter mice with Nphs1 FLPo/FRT-EGFP podocyte reporter mice. Following tamoxifen administration in these animals, CoRL were labeled with red fluorescence (tdTomato) and co-localized with renin. Podocytes were labeled green (enhanced green fluorescent protein) and co localized with nephrin. Following podocyte loss by nephrotoxic antibody and subsequent enalapril-enhanced partial replacement, tdTomato-EGFP-labeled CoRL were detected as yellow-colored cells in a subset of glomerular tufts, without the use of antibodies. Co-localization with podocin indicated that these cells are podocytes, derived from CoRL origin. Thus, our novel study shows that two distinct cell types can be simultaneously labeled in the mouse kidney and provide strong genetic evidence in vivo that lost podocytes can be replaced in part by CoRL. PMID- 29580639 TI - Official batch control of influenza vaccines: Is it still useful? AB - INTRODUCTION: The governmental quality control of human vaccines is a long established tradition in many European countries. In Germany, vaccines have been controlled by a governmental agency since 1935. In the beginning, vaccine production and control was a purely national activity. However, that changed fundamentally in 1994 when the so-called Official Control Authority Batch Release Network (OCABR) was implemented shortly after the establishment of the European Union. Today, Official Medicinal Control Laboratories (OMCLs) are part of the European OCABR Network. In many European countries, OMCLs experimentally test every batch of human vaccines before they enter the market. We wanted to gain insights into the benefits of batch release by the Network and address the question whether batch release is still useful. This question was investigated in the context of influenza vaccines. METHODS: Notifications on influenza vaccines circulated from 2006 to 2016 within the OCABR network were compiled and organized into 32 cases. The impact of these findings was evaluated, and the communication pathways between companies and respective European control laboratories were examined. RESULTS: Approximately 5850 batches were tested by the OMCL network between 2006 and 2016. Among these, notifications belonging to 32 cases were observed. The predominant proportion of the circulated notifications related to manufacturing issues. In most cases, the manufacturer itself had withdrawn the batches before they entered the market. However, in three cases, batches of insufficient quality were detected by the respective European Control Laboratory leading to withdrawal of 13 batches. CONCLUSION: 13 batches which did not meet the specifications of influenza vaccine were detected by the OMCL network between 2006 and 2016 which would not have been identified by the manufacturer. This demonstrates the impact of governmental batch release. Together with the intrinsic values of the OCABR system and keeping in mind that vaccines are given to healthy often young individuals, governmental batch release of influenza vaccines is still justified. PMID- 29580640 TI - A randomized, open label trial to evaluate and compare the immunogenicity and safety of a novel liquid hexavalent DTwP-Hib/Hep B-IPV (EasySixTM) to licensed combination vaccines in healthy infants. AB - : Immunogenicity and safety of a newly developed liquid DTwP-Hib/HepB-IPV hexavalent vaccine (EasySixTM) was evaluated and compared with administration of commercially licensed Pentavac SD(r) (DTwP-HepB/Hib) and Imovax Polio(r) vaccine in an open-label, randomized multi-centric trial. 284 participants, aged 6 10weeks, randomized in a 1:1 allocation, received three doses of test or comparator vaccines, administered 4weeks apart. Immunogenicity of the vaccines was determined by measuring the baseline and post-vaccination antibody responses and comparing the proportions of subjects achieving seroprotection against the vaccine antigens; safety was evaluated in terms of solicited (local and systemic) and unsolicited incidences in the follow up phase. Post-vaccination, seroprotection was achieved against all six vaccine antigens in both vaccine groups. The seroresponse rate as well as geometric mean titers of antibody for all vaccine components were comparable between EasySixTM and Pentavac SD(r) Imovax Polio(r) group. Both vaccines had similar reactogenicity profiles and were well tolerated; all adverse events resolved completely without any sequelae. Only one serious adverse event was reported that completely resolved; it was regarded unconnected to the vaccine administered. This study demonstrated that immunogenicity and safety profiles of EasySixTM vaccine, manufactured by Panacea Biotec Ltd, are non-inferior to the commercially available vaccines.

AB - During the last 12 years, over 80 countries have introduced national HPV vaccination programs. The majority of these countries are high or upper-middle income countries. The barriers to HPV vaccine introduction remain greatest in those countries with the highest burden of cervical cancer and the most need for vaccination. Innovation and global leadership is required to increase and sustain introductions in low income and lower-middle income countries.

AB - Yellow fever (YF) is an acute viral haemorrhagic disease caused by the yellow fever virus (YFV), which remains a potential threat to public health. The live attenuated YF vaccine (17D strain) is a safe and highly effective measure against YF. However, increasing adverse events have been associated with YF vaccinations in recent years; thus, safer, alternative vaccines are needed. In this study, using the Japanese encephalitis live vaccine strain SA14-14-2 as a backbone, a novel chimeric virus was constructed by replacing the pre-membrane (prM) and envelope (E) genes with their YFV 17D counterparts.The chimeric virus exhibited a reduced growth rate and a much smaller plaque morphology than did either parental virus. Furthermore, the chimera was much less neurovirulent than was YF17D and protected mice that were challenged with a lethal dose of the YF virus. These results suggest that this chimera has potential as a novel attenuated YF vaccine.

AB - Haiti has historically vaccinated between 100,000 and 300,000 dogs annually against rabies, however national authorities have not been able to reach and maintain the 70% coverage required to eliminate the canine rabies virus variant. Haiti conducts massive dog vaccination campaigns on an annual basis and utilizes both central point and door-to-door methods. These methods require that dog owners are aware of the dates and locations of the campaign. To improve this awareness among dog owners, 600,000 text messages were sent to phones in two Haitian communes (Gonaives and Saint-Marc) to remind dog owners to attend the campaign. Text messages were delivered on the second day and at the mid-point of the campaign. A post-campaign household survey was conducted to assess dog owner's perception of the text messages and the impact on their participation in the vaccination campaign. Overall, 147 of 160 (91.9%) text-receiving dog owners indicated the text was helpful, and 162 of 187 (86.6%) responding dog owners said they would like to receive text reminders during future rabies vaccination campaigns. In areas hosting one-day central point campaigns, dog owners who received the text were 2.0 (95% CI 1.1, 3.6) times more likely to have participated in the campaign (73.1% attendance among those who received the text vs 36.4% among those who did not). In areas incorporating door-to-door vaccination over multiple days there was no significant difference in participation between dog owners who did and did not receive a text. Text message reminders were well-received and significantly improved campaign attendance, indicating that short message service (SMS) alerts may be a successful strategy in low resource areas with large free roaming dog populations. PMID- 29580644 TI - Intracytoplasmic sperm injection use in states with and without insurance coverage mandates for infertility treatment, United States, 2000-2015. AB - OBJECTIVE: To compare indications and trends in intracytoplasmic sperm injection (ICSI) use for in vitro fertilization (IVF) cycles among residents of states with and without insurance mandates for IVF coverage. DESIGN: Cross-sectional analysis of the National Assisted Reproductive Technology Surveillance System from 2011 to 2015 for the main outcome and from 2000 to 2015 for trends. SETTING: IVF cycles performed in U.S. fertility clinics. PATIENT(S): Fresh IVF cycles. INTERVENTION(S): Residency in a state with an insurance mandate for IVF (n = 8 states) versus no mandate (n = 43 states, including DC). MAIN OUTCOME MEASURE(S): ICSI use by insurance coverage mandate status stratified by male-factor infertility diagnosis. RESULT(S): During 2000-2015, there were 1,356,377 fresh IVF cycles, of which 25.8% (n = 350,344) were performed for residents of states with an insurance coverage mandate for IVF. ICSI use increased significantly during 2000-2015 in states both with and without a mandate; however, for non-male factor infertility cycles, the percentage increase in ICSI use was greater among nonmandate states (34.6% in 2000 to 73.9% in 2015) versus mandate states (39.5% in 2000 to 63.5% in 2015). For male-factor infertility cycles, this percentage increase was ~7.3% regardless of residency in a state with an insurance mandate for IVF. From 2011 to 2015, ICSI use was lower in mandate versus nonmandate states, both for cycles with (91.5% vs. 94.5%), and without (60.3% vs. 70.9%) male-factor infertility. CONCLUSION(S): Mandates for IVF coverage were associated with lower ICSI use for non-male-factor infertility cycles.

PMID- 29580646 TI - Assessment of 30-day mortality and complication rates associated with extended deep vein thrombosis prophylaxis following hip fracture surgery. AB - BACKGROUND: DVT is a common complication following lower extremity surgery, occurring in up to 60% of patients undergoing hip fracture surgery without postoperative anticoagulation. The risk of fatal PE continues well-beyond two weeks postoperatively, thus extended DVT prophylaxis beyond 14 days may be warranted. This investigation sought to examine the association between prescription of extended DVT prophylaxis and 30-day postoperative complications following hip fracture surgery. METHODS: This study utilized the ACS NSQIP Hip Fracture Procedure Targeted dataset, a newly available set of patient variables for 2016. The outcome measures were death, occurrence of any postoperative complication, complication subtype, readmission or reoperation within 30-days postoperatively, and length of stay. The primary independent variable was medical DVT prophylaxis continued 28-days postoperatively ("extended DVT prophylaxis"). The control group contains both patients receiving no prophylaxis and those receiving short-duration prophylaxis. Multivariate stepwise logistic regression was employed to control for potential demographic, comorbidity, and procedural/medical confounding factors. RESULTS: In total, 7533 surgically treated hip fracture patients treated in 2016 were analyzed. Overall, 57.8% of patients (n = 4354) were prescribed extended DVT prophylaxis. On bivariate analysis, prescription of extended DVT prophylaxis was associated with significantly lower incidence of death (7.7% without vs. 2.7% with, p < 0.0001) and stroke/CVA (1.4% vs. 0.6%, p = 0.0016). In multivariate analysis, prescription of extended DVT prophylaxis was significantly associated with lower odds of death (OR 0.33, p < 0.0001), stroke/CVA (OR 0.44, p = 0.0010), and acute kidney injury (AKI) (OR 0.31, p = 0.0010). CONCLUSIONS: This retrospective cohort study of the 2016 ACS NSQIP found that hip fracture surgery patients prescribed >=28 days of postoperative DVT prophylaxis exhibited 67% lower odds of death and significantly lower rates of AKI and stroke/CVA as compared to those prescribed short-duration prophylaxis. Given the retrospective and uncontrolled nature of this analysis, these results should be interpreted with caution, and additional prospective randomized controlled trials examining the association between extended DVT prophylaxis and postoperative outcomes are warranted. If these observations accurately reflect real-world experience, these data suggest that >=28 days of DVT prophylaxis following hip fracture surgery should be strongly considered for patients without explicit contraindications. PMID- 29580647 TI - Evaluation of the DiversiLab(r) automated repetitive sequence-based PCR system for the characterization of Candida albicans and Candida glabrata isolates. AB - The objective of our study was to assess the DiversiLab(r) automated repetitive sequence-based PCR (rep-PCR) system for typing C. albicans and C. glabrata isolates and to compare it with two proven and routinely used typing methods. A total of 39 isolates from 11 patients with candidaemia or tissue candidiasis (two to six isolates per patient) were analyzed with three typing methods: DiversiLab(r) rep-PCR, multilocus sequence typing and multilocus microsatellite typing. DiversiLab(r) rep-PCR results were consistent with those obtained using the two other typing methods for C. albicans, but not for C. glabrata. Thanks to its simplicity of use, rapidity, standardization and reproducibility, the DiversiLab(r) rep-PCR system is an interesting tool to investigate C. albicans infections. PMID- 29580648 TI - Ageing with a learning disability: Care and support in the context of austerity. AB - Recent work in geography has begun to look at the opportunities for care from siblings, friends and neighbours alongside parents and spouses. This paper examines the daily relationships that middle to older age adults with a learning disability have with remaining kin members, friends, and neighbours, within the context of declining formal day services. Adults with learning disabilities are more likely to have different life course experiences and be living on low incomes and in poor housing than the rest of the population as they have had less opportunity to work and save money through their lives. We draw on two qualitative studies with adults with learning disabilities. Findings suggest that friend and kin networks are anything but certain, as opportunities to meet and socialise shrink, and connections with siblings do not necessarily lend themselves to support. The findings raise the possibility of a space of attenuated care to convey the increasingly limited fronts from which support can be derived. PMID- 29580649 TI - Recommendations for newborn screening for galactokinase deficiency: A systematic review and evaluation of Dutch newborn screening data. AB - INTRODUCTION: Galactokinase (GALK) deficiency causes cataract leading to severe developmental consequences unless treated early. Because of the easy prevention and rapid reversibility of cataract with treatment, the Dutch Health Council advised to include GALK deficiency in the Dutch newborn screening program. The aim of this study is to establish the optimal screening method and cut-off value (COV) for GALK deficiency screening by performing a systematic review of the literature of screening strategies and total galactose (TGAL) values and by evaluating TGAL values in the first week of life in a cohort of screened newborns in the Netherlands. METHODS: Systematic literature search strategies in OVID MEDLINE and OVID EMBASE were developed and study selection, data collection and analyses were performed by two independent investigators. A range of TGAL values measured by the Quantase Neonatal Total Galactose screening assay in a cohort of Dutch newborns in 2007 was evaluated. RESULTS: Eight publications were included in the systematic review. All four studies describing screening strategies used TGAL as the primary screening marker combined with galactose-1-phosphate uridyltransferase (GALT) measurement that is used for classical galactosemia screening. TGAL COVs of 2200 MUmol/L, 1665 MUmol/L and 1110 MUmol/L blood resulted in positive predictive values (PPV) of 100%, 82% and 10% respectively. TGAL values measured in the newborn period were reported for 39 GALK deficiency patients with individual values ranging from 3963 to 8159 MUmol/L blood and 2 group values with mean 8892 MUmol/L blood (SD +/- 5243) and 4856 MUmol/L blood (SD +/- 461). Dutch newborn screening data of 72,786 newborns from 2007 provided a median TGAL value of 110 MUmol/L blood with a range of 30-2431 MUmol/L blood. CONCLUSION: Based on TGAL values measured in GALK deficiency patients reported in the literature and TGAL measurements in the Dutch cohort by newborn screening we suggest to perform the GALK screening with TGAL as a primary marker with a COV of 2500 MUmol/L blood, combined with GALT enzyme activity measurement as used in the classical galactosemia screening, to ensure detection of GALK deficiency patients and minimize false positive referrals. PMID- 29580650 TI - Significance of PITX2 Promoter Methylation in Colorectal Carcinoma Prognosis. AB - BACKGROUND: New treatment modalities and a growing understanding of the complex genetic tumor landscape have improved the outcome of colorectal cancer (CRC) patients. Nonetheless, more individualized treatment regimens, taking individual tumor characteristics into account, have been recently postulated and prognostic biomarkers are needed. We therefore evaluated the prognostic potential of paired like homeodomain transcription factor 2 (PITX2) promoter methylation in CRC patients. MATERIALS AND METHODS: Data of 2 independent cohorts were investigated. Tissue specimens of cohort A (n = 179) were analyzed for their methylation in the PITX2 promoter region using quantitative methylation-specific polymerase chain reaction and compared with publicly available data (PITX2 promoter methylation and PITX2 mRNA expression levels) from "The Cancer Genome Atlas Research Network" (cohort B, n = 443). Data were correlated with clinicopathological parameters and outcome. RESULTS: Tumor samples of both cohorts showed a decreased PITX2 promoter methylation level (both P < .001) compared with nonmalignant tissue. Additionally, PITX2 promoter hypomethylation was prognostic in univariate and multivariate analysis (hazard ratio [HR], 1.97 [95% confidence interval (CI), 1.12-3.47], P = .018 and HR, 1.89 [95% CI, 1.09-3.29], P = .023), and Kaplan Meier analysis (median overall survival, 53.2 vs. 70.4 months, P = .004). Subanalysis of high-risk vs. low-risk stage II CRC patients also showed a PITX2 hypomethylation of the promoter region in the high-risk group (P = .006). CONCLUSION: Our results suggest a prognostic role of PITX2 promoter methylation in CRC as biomarker for risk stratification in stage II CRC patients although the results need to be independently validated. PMID- 29580651 TI - [Ocular tuberculosis : A case series]. AB - OBJECTIVES: Ocular tuberculosis is a rare form of extra pulmonary tuberculosis. It represents 1-2% of all clinical forms. The aim of this work was to focus on diagnostic and therapeutic characteristics of ocular tuberculosis. METHODS: We report a case series of 14 patients with ocular tuberculosis seen in an infectious diseases department between 2006 and 2015. The diagnosis was retained on clinical data and a positive tuberculin skin test or interferon-gamma release assay. RESULTS: The patient's mean age was 40.7+/-9years. The most common clinical presentation was uveitis (11 patients and 16 eyes). An extra ocular involvement was associated in three patients. The mean duration of antitubercular therapy was 10+/-2.5 months. Corticosteroid therapy was associated in 11 cases. The outcome was favorable in all cases. Two patients had maintained visual sequelae. CONCLUSION: Ocular tuberculosis is a rare disease but still remains a diagnostic problem. It should be considered in case of any chronic ocular symptoms, especially in endemic countries. Early management can improve the visual prognosis. PMID- 29580652 TI - Gambling behavior in Parkinson's Disease: Impulsivity, reward mechanism and cortical brain oscillations. AB - Psychopathological components, such as reward sensitivity and impulsivity, and dopaminergic treatment are crucial characteristics related to the development of Pathological Gambling (PG) in Parkinson's Disease (PD). The aim of the present study is to investigate the differences in decision-making in PD patients with or without PG considering both neurophysiological and behavioral aspects. The IOWA Gambling Task (IGT) and electroencephalographic (EEG) activity were considered to elucidate the decision and post-feedback processes in PG. The sample included fifty-two PD patients, divided in three groups: 17 PD patients with active gambling behavior (PD Gamblers, PDG); 15 PD patients who remitted from PG (PD Non Gamblers, PDNG); and a Control Group (CG) composed by 20 patients with PD only. EEG and IGT performance were recorded during decision and post-feedback phase. Results showed worse performance and an increase of the low frequency bands in the frontal area for the PDG group compared to the other two groups. In addition, higher BAS (Behavioral Activation System) and BIS-11 (Barratt Impulsiveness Scale) personality components were correlated to groups' behavioral response. These results show an anomalous behavioral (IGT) and cortical response of PDG patients related to their inability to use adequate control mechanisms during a decision-making task where reward mechanisms (BAS) and impulsivity (BIS-11) are relevant.

PMID- 29580655 TI - Protection of the rat brain from hypothermic circulatory arrest injury by a chipmunk protein. AB - OBJECTIVES: The study objectives were to test the hypothesis that special protein exists in hibernating chipmunk albumin and whether this protein has a neuroprotective effect in Sprague-Dawley rats during deep hypothermia circulatory arrest. METHODS: Forty chipmunks were allocated into a hibernation group and an active group (20 chipmunks in each group). Special protein was detected and isolated from hibernating chipmunk albumin. Forty Sprague-Dawley rats were randomly divided into a sham group, deep hypothermia circulatory arrest group, special protein group, and naloxone group (10 rats in each group). Special protein that was detected and collected from hibernating chipmunks were injected in rats in the special protein group for 3 consecutive days before operation, and naloxone was given at the same time in the naloxone group. Rats were subjected to cardiopulmonary bypass and 60-minute deep hypothermia circulatory arrest. Tumor necrosis factor-alpha and interleukin-6 levels were detected. Animals received neurologic testing. Relative protein expression, malondialdehyde, and superoxide dismutase of hippocampus were detected. The brain was fixed for histopathologic assessment. RESULTS: The rats that received special protein displayed ischemic tolerance after deep hypothermia circulatory arrest. The neuroprotective effect could be reversed by naloxone. The inflammation response was attenuated in the special protein group (P < .008, compared with the deep hypothermia circulatory arrest and naloxone groups). The mature brain-derived neurotrophic factor and SIRT1 levels were higher in the special protein group (P < .01, compared with the deep hypothermia circulatory arrest and naloxone groups). Histopathologic assessment showed that the injury in the special protein group was attenuated (pathological score, P < .05; surviving hippocampal CA1 neurons, P < .01; TUNEL positive neurons, P < .01; compared with deep hypothermia circulatory arrest and naloxone groups). Intravenous injection of special protein significantly improved neurologic recovery. CONCLUSIONS: We found that a specific protein existed in hibernating chipmunk albumin and could play an important neuroprotective role in rats.

PMID- 29580658 TI - Transcutaneous Auricular Vagus Nerve Stimulation with Concurrent Upper Limb Repetitive Task Practice for Poststroke Motor Recovery: A Pilot Study. AB - BACKGROUND: Invasive vagus nerve stimulation (VNS) has the potential to enhance the effects of physiotherapy for upper limb motor recovery after stroke. Noninvasive, transcutaneous auricular branch VNS (taVNS) may have similar benefits, but this has not been evaluated in stroke recovery. We sought to determine the feasibility of taVNS delivered alongside upper limb repetitive task specific practice after stroke and its effects on a range of outcome measures evaluating limb function. MATERIALS AND METHODS: Thirteen participants at more than 3 months postischemic stroke with residual upper limb dysfunction were recruited from the community of Sheffield, United Kingdom (October-December 2016). Participants underwent 18 * 1-hour sessions over 6 weeks in which they made 30-50 repetitions of 8-10 arm movements concurrently with taVNS (NEMOS; Cerbomed, Erlangen, Germany, 25 Hz, .1-millisecond pulse width) at maximum tolerated intensity (mA). An electrocardiogram and rehabilitation outcome scores were obtained at each visit. Qualitative interviews determined the acceptability of taVNS to participants. RESULTS: Median time after stroke was 1.16 years, and baseline median/interquartile range upper limb Fugl-Meyer (UFM) score was 63 (54.5-99.5). Participants attended 92% of the planned treatment sessions. Three participants reported side effects, mainly fatigue, but all performed mean of more than 300 arm repetitions per session with no serious adverse events. There was a significant change in the UFM score with a mean increase per participant of 17.1 points (standard deviation 7.8). CONCLUSION: taVNS is feasible and well tolerated alongside upper limb repetitive movements in poststroke rehabilitation. The motor improvements observed justify a phase 2 trial in patients with residual arm weakness. PMID- 29580659 TI - Impact of iron deficiency on long-term clinical outcomes of hospitalized patients with heart failure. AB - BACKGROUND: Iron deficiency (ID) is commonly observed in chronic heart failure (HF) patients and is associated with worse clinical outcomes. While ID is frequent finding in hospitalized heart failure (HHF), its impact on long-term outcome in HHF patients remains unclear. METHODS: We evaluated iron status at discharge in 578 HHF patients. Absolute ID was defined as serum ferritin <100 MUg/L, and functional ID (FID) was defined as serum ferritin of 100-299 MUg/L with transferrin saturation <20%. The primary outcome of interest was the composite of all-cause mortality and HF admission at one year. RESULTS: Among the study population, 185 had absolute ID, 88 had FID and 305 had no evidence of ID. At one-year post-discharge, 64 patients had died and 112 had been readmitted with HF. Patients with absolute ID had more adverse events than those with FID or no ID (p = 0.021). In multivariate Cox regression analyses, absolute ID was significantly associated with increased risk of adverse events at one year (HR 1.50, 95% CI 1.02-2.21, p = 0.040) compared with the remaining patients. Sensitivity analysis revealed that its prognostic effect did not differ across anemic status, or between HF with reduced and preserved ejection fraction (p for interaction = 0.17, 0.68, respectively). CONCLUSION: Absolute ID, but not FID, at discharge was associated with increased risk of one-year mortality or HF admission in patients with HHF. Further studies are required to evaluate the role of repleting iron stores and its impact on clinical outcomes in patients with HHF.

PMID- 29580660 TI - CKD Self-management: Phenotypes and Associations With Clinical Outcomes. AB - BACKGROUND: To slow chronic kidney disease (CKD) progression and its complications, patients need to engage in self-management behaviors. The objective of this study was to classify CKD self-management behaviors into phenotypes and assess the association of these phenotypes with clinical outcomes. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Adults with mild to moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study. 3,939 participants in the CRIC Study recruited between 2003 and 2008 served as the derivation cohort and 1,560 participants recruited between 2013 and 2015 served as the validation cohort. PREDICTORS: CKD self-management behavior phenotypes. OUTCOMES: CKD progression, atherosclerotic events, heart failure events, death from any cause. MEASUREMENTS: Latent class analysis stratified by diabetes was used to identify CKD self-management phenotypes based on measures of body mass index, diet, physical activity, blood pressure, smoking status, and hemoglobin A1c concentration (if diabetic); Cox proportional hazards models. RESULTS: 3 identified phenotypes varied according to the extent of implementation of recommended CKD self-management behaviors: phenotype I characterized study participants with the most recommended behaviors; phenotype II, participants with a mixture of recommended and not recommended behaviors; and phenotype III, participants with minimal recommended behaviors. In multivariable-adjusted models for those with and without diabetes, phenotype III was strongly associated with CKD progression (HRs of 1.82 and 1.49), death (HRs of 1.95 and 4.14), and atherosclerotic events (HRs of 2.54 and 1.90; each P < 0.05). Phenotype II was associated with atherosclerotic events and death among those with and without diabetes. LIMITATIONS: No consensus definition of CKD self-management; limited to baseline behavior data. CONCLUSIONS: There are potentially 3 CKD self-management behavior phenotypes that distinguish risk for clinical outcomes. These phenotypes may inform the development of studies and guidelines regarding optimal self management. PMID- 29580663 TI - Asian Fish Tapeworm: The Most Successful Invasive Parasite in Freshwaters. AB - The Asian fish tapeworm (AFT), Schyzocotyle acheilognathi, is a notorious and highly successful invasive parasite reported in a wide spectrum of freshwater fishes, and new reports of its spread continue to emerge. To date, no thorough review of its worldwide distribution and host associations is available. In the present work, we collected information from 651 articles up until 2017, from which we updated the number of the hosts to 312 fish species and 11 non-fish species, which is quite unusual among helminths. The AFT has spread to all but one continent (Antarctica). The highest number of records are from North America, followed by Asia and Europe. A key feature of its invasive success is its broad environmental tolerance. PMID- 29580664 TI - Diabetes mellitus as a protective factor of abdominal aortic aneurysm: Possible mechanisms. AB - Abdominal aortic aneurysm (AAA) shares several risk factors with atherosclerosis. Among these, diabetes mellitus (DM) could have a negative effect on the formation, growth and expansion of AAA. Several systematic reviews and meta analyses reported up to 2016 have shown concordant results regarding the possible protective effect on AAA formation. However, the pathophysiological mechanisms of this supposed protective effect are still unknown. It appears that both hyperglycaemia and hyperinsulinemia, which are closely associated with DM, cause an increase in advanced glycation end-products, a decrease in fibrinolysis, and alterations in smooth muscle cells, leading to a decreased risk of aneurysm growth and expansion. This protective role is mainly mediated by a decrease in metalloproteinases, mainly type 2 and 9. In addition, drugs used to treat type 2 DM, as well as those for hypertension and dyslipidaemia could also play an important role in this protective effect. Metformin, thiazolidinediones, DPP4 inhibitors, statins, and angiotensin-converting enzyme inhibitors have been evaluated in this field. In conclusion, studies reported so far seem to confirm the protective effect of DM in both the formation and expansion of AAA, although future long-term studies are needed to confirm the pathophysiological mechanisms involved, as well as the role of concomitant medication. PMID- 29580662 TI - Duration of Living Kidney Transplant Donor Evaluations: Findings From 2 Multicenter Cohort Studies. AB - BACKGROUND: A prolonged living kidney donor evaluation may result in worse outcomes for transplant recipients. Better knowledge of the duration of this process may help inform future donors and identify opportunities for improvement. STUDY DESIGN: 1 prospective and 1 retrospective cohort study. SETTING & PARTICIPANTS: At 16 Canadian and Australian transplantation centers (prospective cohort) and 5 Ontario transplantation centers (retrospective cohort), we assessed the duration of living kidney donor evaluation and explored donor, recipient, and transplantation factors associated with longer evaluation times. Data were obtained from 2 sources: donor medical records using chart abstraction and health care administrative databases. PREDICTORS: Donor and recipient demographics, direct versus paired donation, center-level variables. OUTCOMES: Duration of living donor evaluation. RESULTS: The median total duration of transplantation evaluation (time from when the candidate started the evaluation until donation) was 10.3 (IQR, 6.5-16.7) months. The median duration from evaluation start until approval to donate was 7.9 (IQR, 4.6-14.1) months, and from approval until donation was 0.7 (IQR, 0.3-2.4) months, respectively. The median time between the first and last consultation among donors who completed a nephrology, surgery, and psychosocial assessment in the prospective cohort was 3.0 (IQR, 1.0-6.3) months, and between computed tomography angiography and donation was 4.8 (IQR, 2.6-9.2) months. After adjustment, the total duration of transplantation evaluation was longer if the donor participated in paired donation (6.6 [95% CI, 1.6-9.7] months) and if the recipient was referred later relative to the donor's evaluation start date (0.9 [95% CI, 0.8-1.0] months [per month of delayed referral]). Results depended on whether the recipient was receiving dialysis. LIMITATIONS: Living donor candidates who did not donate were not included and proxy measures were used for some dates in the donor evaluation process. CONCLUSIONS: The duration of kidney transplant donor evaluation is variable and can be lengthy. Better understanding of the reasons for a prolonged evaluation may inform quality improvement initiatives to reduce unnecessary delays. PMID- 29580665 TI - Low T3 syndrome improves risk prediction of in-hospital cardiovascular death in patients with acute myocardial infarction. AB - BACKGROUND: Low triiodothyronine (T3) syndrome (LT3S) is frequently seen in patients with acute myocardial infarction (AMI). We examined the association between LT3S and severity of myocardial injury and determined whether LT3S adds predictive value over thrombolysis in myocardial infarction (TIMI) risk score for in-hospital cardiovascular (CV) death. METHODS: Of 2459 AMI patients, 529 pairs of euthyroid and LT3S individuals with similar baseline characteristics were identified using 1:1 propensity score matching. LT3S was defined as free T3 (fT3) <2.36pg/mL, normal values of thyroid-stimulating hormone and free thyroxin. Primary outcome was in-hospital CV death. Receiver operating characteristic curves were generated to assess the predictive effects of fT3, TIMI risk score, and TIMI-LT3S risk score on in-hospital CV death. RESULTS: LT3S was found in 23.3% of patients with AMI. The peak values of cardiac troponin I in ng/mL and N terminal pro-brain natriuretic peptide in ng/mL were significantly higher in LT3S: 6.6 (1.3-19.6) vs. 3.5 (0.8-12.1), p<0.001 and 3625 (1046-12,776) vs. 2158 (774-6759), p<0.001. Patients with LT3S had significantly higher rate of in hospital CV death than those without (4.7% vs. 1.7%, p=0.005). Lower levels of fT3 yielded an area under the curve (AUC) of 0.741 for predicting CV death. LT3S, when added to the TIMI risk score, significantly increased AUC for in-hospital CV death than TIMI risk score alone (0.775 vs. 0.738, p=0.005). CONCLUSIONS: LT3S was associated with more severe myocardial injury and increased in-hospital CV mortality in patients with AMI. Furthermore, it improved risk prediction of in hospital CV death post-AMI when it was added to the TIMI risk score.

AB - BACKGROUND: This study aimed to evaluate cross-cultural adaptation, validation, and reliability of Patient and Observer Scar Assessment Scale (POSAS) for its Turkish use. METHOD: This study included 50 burn patients with hypertrophic scars who were aged 18-65 years (mean, 37.5+/-1.4years) and were admitted to Wound and Burn Treatment Center from February 2014 to April 2014. With regard to the cultural adaptation of POSAS from English to Turkish, the scale was translated by two people who worked in different health fields. POSAS was administered to the patients with a 1-week interval to evaluate the validity and reliability of the scale. Internal consistency of the scale was tested using the Cronbach alphamethod. RESULTS: The Cronbach alpha value for the observer measurements was found to be 0.93 (excellent), and that for patient measurements was found to be 0.77 (good). Accordingly, the internal consistency of the scale was established. CONCLUSION: The Turkish version of POSAS is a valid, reliable and culturally appropriate survey for evaluating hypertrophic scars. We believe that the Turkish version of POSAS will be an important clinical/scientific tool in the field of burn physiotherapy in Turkey, which will lead to new researches in this field.

PMID- 29580668 TI - Medication-related osteonecrosis of the jaw: An update on the memorial sloan kettering cancer center experience and the role of premedication dental evaluation in prevention. AB - OBJECTIVE: The aim of this study was to investigate the relationship between type of antiresorptive medication and medication-related osteonecrosis of the jaw (MRONJ) onset and the role of premedication dental evaluation (PMDE) in the prevention of MRONJ. STUDY DESIGN: Our database of patients with MRONJ was reviewed. The Kruskal-Wallis test was used to analyze the onset dose of the 3 frequent medication types associated with MRONJ. To evaluate the role of PMDE in the prevention of MRONJ, all patients on antiresorptive and/or antiangiogenic medications seen in the Dental Service of Memorial Sloan Kettering Cancer Center during a 10-year period were subclassified into 2 groups. Group I comprised patients seen for PMDE before the commencement of A/A and group II patients seen after prior exposure to antiresorptive and/or antiangiogenic medications. Fischer's exact test was used to compare the incidence of MRONJ in both groups. RESULTS: Patients on denosumab developed MRONJ earlier compared with zoledronate and pamidronate (P = .003). Group I had a significantly reduced incidence of MRONJ (0.9%) compared with group II (10.5%) (P < .0001). Dentoalveolar trauma as a precipitating factor between groups I and II was not statistically significant. CONCLUSIONS: Denosumab was associated with an earlier occurrence of MRONJ compared with zoledronate and pamidronate. The role of PMDE may be an effective preventive strategy in reducing the incidence of MRONJ.

AB - OBJECTIVE: Adenoid cystic carcinoma (ACC) is characterized by a high rate of local recurrence and late distant metastasis. The status of an elective neck dissection (END) is controversial in the literature. STUDY DESIGN: In this study we retrospectively analyzed the surgical treatment and follow-up examinations of 59 patients with ACCs of a salivary gland treated in a single center between 1980 and 2016. RESULTS: The incidence of occult nodal metastases among all patients who underwent END was 20.6%. The overall survival and the disease-free survival of patients who underwent END versus patients without END had no significant differences. Even in the case of positive lymph nodes metastasis there was no significant benefit in survival or local recurrence control. CONCLUSION: The incidence of occult neck metastases in patients with ACC was 20.6%. There was no significant enhanced survival in the group of patients who underwent an END.

AB - INTRODUCTION: Individuals in early stages of Alzheimer's disease are a targeted population for secondary prevention trials aimed at preserving normal cognition. Understanding within-person biomarker(s) change over time is critical for trial enrollment and design. METHODS: Longitudinal cerebrospinal fluid samples from the Alzheimer's Disease Neuroimaging Initiative were assayed for novel markers of neuronal/synaptic injury (visinin-like protein 1, Ng, and SNAP-25) and neuroinflammation (YKL-40) and compared with beta amyloid 42, tau, and phospho tau181. General linear mixed models were used to compare within-person rates of change in three clinical groups (cognitively normal, mild cognitive impairment, and Alzheimer's disease) further defined by beta amyloid status. RESULTS: Levels of injury markers were highly positively correlated. Despite elevated baseline levels as a function of clinical status and amyloid-positivity, within-person decreases in these measures were observed in the early symptomatic, amyloid positive Alzheimer's disease group. DISCUSSION: Knowledge of within-person biomarker change will impact interpretation of biomarker outcomes in clinical trials that are dependent on disease stage. PMID- 29580671 TI - Intron-retained transcripts of the spinal muscular atrophy genes, SMN1 and SMN2. AB - BACKGROUND: The SMN genes, SMN1 and SMN2, are highly homologous genes which are related to the development or clinical severity of spinal muscular atrophy. Some alternative splicing patterns of the SMN genes have been well documented. In 2007, an SMN1 transcript with a full sequence of intron 3 was reported as the first intron-retained SMN transcript. METHODS: Intron-retained SMN transcripts in various cells and tissues were studied using reverse transcription (RT)-PCR. HeLa cells were used for subcellular localization of the transcripts and protein expression analysis with Western blotting. RESULTS: Two intron-retained SMN transcripts were detected, which contain full sequences of intron 2b or intron 3. These transcripts were produced from SMN1 and SMN2, and ubiquitously expressed in human cells and tissues. Western blotting analysis showed no proteins derived from the intron-retained transcripts. Fractionation analysis showed that these intron-retained transcripts were localized mainly in the nucleus. Contrary to our expectation, the intron-retained transcript levels decreased during the treatment of cycloheximide, an inhibitor of nonsense-mediated decay (NMD), suggesting that they were not targets of NMD. CONCLUSION: Intron 2b-retained SMN transcript and intron3-retained SMN transcript were ubiquitously expressed in human cells and tissues. The intron-retained transcripts were mainly localized in the nucleus and decreased through non-NMD pathway. PMID- 29580672 TI - Athlete's heart and soldier's heart: Is Morganroth striking back? PMID- 29580673 TI - Using a social construction of gender lens to understand gender differences in posttraumatic stress disorder. AB - A wealth of research has established clear gender differences in exposure to potentially traumatic events and in subsequent posttraumatic stress disorder (PTSD). One perspective that is missing from most conversations about gender differences in PTSD is a systematic discussion of gender role socialization, and relatedly, the social construction of gender within our society. The purpose of the present review is to provide exposure to these theories as they relate to gender differences in PTSD, including differences in trauma exposure, risk for the development and maintenance of PTSD symptoms, and PTSD treatment outcome. In this review we focus on characteristics and behaviors that arise from a way of being in the world that is largely influenced by assigned gender. These include gender differences in patterns of trauma exposure, chronic environmental strain, behavioral responses to distress, cognitive factors, and the experience and expression of emotion. We posit that these different sets of factors reciprocally influence each other and combine synergistically to influence observed gender differences. The research reviewed here indicates that societal definitions of masculinity and femininity have psychological consequences in that they produce gender differences in major risk factors relevant to PTSD.

AB - This study aimed to analyze the medication use and related falls risk of central nervous system(CNS) drugs in oncology inpatients, explore the association between CNS drugs and falls. In this study, we enrolled inpatients, hospitalized in the oncology department of the Teaching Hospital of Chengdu University of Traditional Chinese Medicine, from March 2013 to October 2015. All inpatients were divided into two groups: taking-CNS drugs group (treatment group) and non CNS drugs group (control group). The falls risk between two groups were being compared and analyzed. Results showed that a total of 768 inpatients were enrolled in this study; 401 of them were males and 367 were females; the average age was 47.9+/ 5.8 year-old. Of them, 129 were taking CNS drugs, while 639 were not. In the treatment group, the number of fall patients was 39, at an incidence rate of 30.23%; of the 39 fall patients, 3 suffered fractures, and 1 suffered an intracranialhemorrhage; while in the control group, the incidence of falls totaled at 45, at an incidence rate of 7.04%; 4 of the patients suffered fractures. The difference of incidence rate between two groups had statistical significance (P< 0.01). The incidence rate of falls in the treatment group was 4.29 times that in the control group. By the further analysis of CNS drugs, results implied that hypnotics, sedatives, selective serotonin reuptake inhibitors (no patient taking tricyclic antidepressants in this study), opioids, antiepileptics and antipsychotics had relationship with falls (OR>1). Our finding indicates that oncology inpatients have a higher risk of falls resulting from taking CNS drugs. Therefore, it is necessary to build up a systemic mechanism of nursing safety management on preventing falls of oncology inpatients, to improve nursing quality, and reduce the risk of falls. PMID- 29580675 TI - Evaluating the Current Status of Rectal Cancer Care in the US: Where We Stand at the Start of the Commission on Cancer's National Accreditation Program for Rectal Cancer. AB - BACKGROUND: In an effort to improve the quality of rectal cancer care in the US, the American College of Surgeons Commission on Cancer has developed the National Accreditation Program for Rectal Cancer (NAPRC). We aimed to describe the current status of rectal cancer care before implementation of the NAPRC. STUDY DESIGN: The 2011-2014 National Cancer Database was queried for non-metastatic rectal cancer patients who underwent proctectomy. The NAPRC process measures evaluated included clinical staging completion, treatment starting fewer than 60 days from diagnosis, CEA level drawn before treatment, tumor regression grading, and margin assessment. The NAPRC performance measures included negative proximal, distal, and circumferential margins, and >=12 lymph nodes harvested during resection. RESULTS: There were 39,068 patients identified (mean age 62 years, 61.6% male sex). In >85% of patients, clinical staging was completed, treatment was started within 60 days, and all tumor margins were assessed. Pretreatment CEA level (64.6% complete) was the process measure most often omitted. However, completion of all included process measures occurred in only 28.1% of patients. All pathologic margins were negative in 79.8% of patients and 73.2% of specimens reported >=12 lymph nodes. Overall, 56.3% of patients achieved all performance measures. Patients treated at high-volume centers (>30 cases/year) had higher odds of meeting all performance measures (odds ratio 1.42; p < 0.001). CONCLUSIONS: Overall, very few patients achieved all of the proposed quality measures for rectal cancer care. It will be important to re-evaluate these data after the implementation of the NAPRC.

AB - OBJECTIVES: To compare the mean number of medical and psychiatric hospital-based services in children with and without attention deficit hyperactivity disorder (ADHD) and to assess the effect of ADHD on hospital-based service use, including child-, parental-, and socioeconomic-related risk factors. STUDY DESIGN: A Danish birth cohort was followed through 12 years, and children with ADHD were identified using Danish nationwide registries. Poisson regression analyses were used to assess the association of ADHD with service use and to adjust for a comprehensive set of explanatory variables. RESULTS: Children diagnosed with ADHD used more medical and psychiatric hospital-based healthcare than those without ADHD. In children with ADHD, intellectual disability and parental psychiatric disorder were associated with increased medical and psychiatric service use. Low birth weight and low gestational age were associated with increased medical service use. Psychiatric comorbidity and having a divorced or single parent were associated with increased psychiatric service use. CONCLUSIONS: ADHD independently affected medical and psychiatric hospital-based service use even when adjusting for a comprehensive set of explanatory variables. However, the pattern of medical and psychiatric hospital-based service use is complex and cannot exclusively be explained by the child-, parental-, and socioeconomic related variables examined in this study. PMID- 29580679 TI - Accuracy of Pulse Oximetry Screening for Critical Congenital Heart Defects after Home Birth and Early Postnatal Discharge. AB - OBJECTIVE: To assess the accuracy of pulse oximetry screening for critical congenital heart defects (CCHDs) in a setting with home births and early discharge after hospital deliveries, by using an adapted protocol fitting the work patterns of community midwives. STUDY DESIGN: Pre- and postductal oxygen saturations (SpO2) were measured >=1 hour after birth and on day 2 or 3. Screenings were positive if the SpO2 measurement was <90% or if 2 independent measures of pre- and postductal SpO2 were <95% and/or the pre-/postductal difference was >3%. Positive screenings were referred for pediatric assessment. Primary outcomes were sensitivity, specificity, and false-positive rate of pulse oximetry screening for CCHD. Secondary outcome was detection of noncardiac illnesses. RESULTS: The prenatal detection rate of CCHDs was 73%. After we excluded these cases and symptomatic CCHDs presenting immediately after birth, 23 959 newborns were screened. Pulse oximetry screening sensitivity in the remaining cohort was 50.0% (95% CI 23.7-76.3) and specificity was 99.1% (95% CI 99.0-99.2). Pulse oximetry screening was false positive for CCHDs in 221 infants, of whom 61% (134) had noncardiac illnesses, including infections (31) and respiratory pathology (88). Pulse oximetry screening did not detect left-heart obstructive CCHDs. Including cases with prenatally detected CCHDs increased the sensitivity to 70.2% (95% CI 56.0-81.4). CONCLUSION: Pulse oximetry screening adapted for perinatal care in home births and early postdelivery hospital discharge assisted the diagnosis of CCHDs before signs of cardiovascular collapse. High prenatal detection led to a moderate sensitivity of pulse oximetry screening. The screening also detected noncardiac illnesses in 0.6% of all infants, including infections and respiratory morbidity, which led to early recognition and referral for treatment. PMID- 29580681 TI - Head-to-tail macrocyclization of cysteine-free peptides using an o-aminoanilide linker. AB - A head-to-tail macrocyclization protocol for the preparation of cysteine-free cyclic peptides was investigated. The o-aminoanilide linker constructed in the peptide sequence by a standard Fmoc-based peptide synthesis procedure was subjected to nitrite-mediated activation under acidic conditions toward N-acyl benzotriazole as the active ester species. The subsequent cyclization smoothly proceeded by neutralization in the presence of additives such as 1 hydroxybenzotriazole (HOBt) and 1-hydroxy-7-azabenzotriazole (HOAt) to afford the expected cyclic pentapeptide, a CXCR4 antagonist. The cyclization efficiencies were dependent on the precursor open-chain sequence. The application of this step wise activation-cyclization protocol to microflow reaction systems is also described. PMID- 29580682 TI - Dose-Dependent Prevention of Metabolic and Neurologic Disease in Murine MPS II by ZFN-Mediated In Vivo Genome Editing. AB - Mucopolysaccharidosis type II (MPS II) is an X-linked recessive lysosomal disorder caused by deficiency of iduronate 2-sulfatase (IDS), leading to accumulation of glycosaminoglycans (GAGs) in tissues of affected individuals, progressive disease, and shortened lifespan. Currently available enzyme replacement therapy (ERT) requires lifelong infusions and does not provide neurologic benefit. We utilized a zinc finger nuclease (ZFN)-targeting system to mediate genome editing for insertion of the human IDS (hIDS) coding sequence into a "safe harbor" site, intron 1 of the albumin locus in hepatocytes of an MPS II mouse model. Three dose levels of recombinant AAV2/8 vectors encoding a pair of ZFNs and a hIDS cDNA donor were administered systemically in MPS II mice. Supraphysiological, vector dose-dependent levels of IDS enzyme were observed in the circulation and peripheral organs of ZFN+donor-treated mice. GAG contents were markedly reduced in tissues from all ZFN+donor-treated groups. Surprisingly, we also demonstrate that ZFN-mediated genome editing prevented the development of neurocognitive deficit in young MPS II mice (6-9 weeks old) treated at high vector dose levels. We conclude that this ZFN-based platform for expression of therapeutic proteins from the albumin locus is a promising approach for treatment of MPS II and other lysosomal diseases. PMID- 29580683 TI - Mandibular reconstruction with free fibula flaps in the elderly: a retrospective evaluation. AB - The purpose of this study was to evaluate surgical outcomes in elderly patients who had undergone free fibula flap transfer for malignant head and neck tumours. A retrospective chart review was performed to identify patients who had undergone free fibula flap transfer for mandibular reconstruction after malignant tumour resection at Jichi Medical University Hospital between May 2009 and April 2015. Enrolled patients were divided into an elderly group (>=80years old) and a younger group (<80years old). Seventeen patients met the inclusion criteria and were included in the elderly group. Age at surgery ranged from 80 to 92years. Thirteen patients (76.5%) experienced postoperative complications. Surgical site complications occurred in seven patients. The success rate of free fibula flap transfer was 100%. Systemic complications occurred in nine patients, most commonly delirium (n=6). No perioperative mortality was encountered. The overall 1-year survival rate was 94.1% (16/17). No patient reported gait disturbance as a donor site complication or any other major complication. The incidence of postoperative complications did not differ significantly between the elderly and younger groups. Almost no difference in postoperative course was seen between the groups. Elderly patients appear to tolerate free fibula flap reconstruction just as well as younger patients. PMID- 29580684 TI - Comparison of 3 Types of Readmission Rates for Measuring Hospital and Surgeon Performance After Primary Total Hip and Knee Arthroplasty. AB - BACKGROUND: All-cause 30-day hospital readmission is in widespread use for monitoring and incentivizing hospital performance for patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, little is known on the extent to which all-cause readmission is influenced by hospital or surgeon performance and whether alternative measures may be more valid. METHODS: This is an observational study using multilevel modeling on English administrative data to determine the interhospital and intersurgeon variation for 3 readmission metrics: all-cause, surgical, and return-to-theater. Power calculations estimated the likelihood of identifying whether the readmission rate for a surgeon or hospital differed from the national average by a factor of 1.25, 1.5, 2, or 3 times, for both average and high-volume providers. RESULTS: 259,980 THAs and 311,033 TKAs were analyzed. Variations by both surgeons and hospitals were smaller for the all-cause measure than for the surgical or return-to-theater metrics, although statistical power to detect differences was higher. Statistical power to detect surgeon-level rates of 1.25 or 1.5 times the average was consistently low. However, at the hospital level, the surgical readmission measure showed more variation by hospital while maintaining excellent power to detect differences in rates between hospitals performing the average number of THA or TKA cases per year in England. In practice, more outliers than expected from purely random variation were found for all-cause and surgical readmissions, especially at hospital level. CONCLUSION: The 30-day surgical readmission rate should be considered as an adjunctive measure to 30-day all-cause readmission rate when assessing hospital performance. PMID- 29580685 TI - Systematic review and pooled analysis of the rate of carpal tunnel syndrome after prophylactic carpal tunnel release in patients with a distal radius fracture. AB - The aim of this study was to determine the rate of carpal tunnel syndrome (CTS) in patients with a volar plated distal radius fracture (DRF), with or without prophylactic carpal tunnel release (CTR). The PubMed database was searched for studies reporting on CTS in patients with a DRF fixed by a volar plate. Selected patients were those who underwent prophylactic CTR versus patients who did not. Pooled rates of CTS were calculated using inverse - variance weighting assuming a random effects model. Tests for heterogeneity were applied. In this study, 172 patients in the CTR group and 1839 patients in the non-CTR group were included. The pooled rate for CTS in the CTR group was 28.1% (95% CI: 11.8% to 48.2%) while it was 4.4% (95% CI: 3.1% to 6.0%) in the non-CTR group. CTR is of no prophylactic value for postoperative CTS in volar plated DRF patients. PMID- 29580686 TI - Relationship between pain and hesitation during movement initiation after distal radius fracture surgery: A preliminary study. AB - We investigated the relationship between pain and hesitation during movement initiation among 11 adult female patients who had undergone surgery for a distal radius fracture. Data on the patients' pain at rest, pain during movement and score on the Pain Catastrophizing Scale were analyzed. Movement characteristics were assessed by the administration of a finger tapping (FT) task using the thumb and index finger, with the movement repeated 10 times, recorded and analyzed to determine the patient's hesitation when opening or closing her thumb/forefinger during the task. Hesitation of movement initiation was significantly correlated with subjective factors such as pain at rest, pain during movement, and rumination. Pain was not significantly correlated with the physical range of motion. Our findings suggest that hesitation during movement initiation for the FT task may be a type of behavior that is affected by subjective pain. Movement hesitation is a novel clinical sign indicating the possible progression of acute pain into chronic pain. The kinematic evaluation described herein is a convenient clinical measurement that captures a subjective factor. PMID- 29580687 TI - Beadex, a Drosophila LIM domain only protein, function in follicle cells is essential for egg development and fertility. AB - LIM domain, constituted by two tandem C2H2 zinc finger motif, proteins regulate several biological processes. They are usually found associated with various functional domains like Homeodomain, kinase domain and other protein binding domains. LIM proteins that are devoid of other domains are called LIM only proteins (LMO). LMO proteins were first identified in humans and are implicated in development and oncogenesis. They regulate various cell specifications by regulating the activity of respective transcriptional complexes. The Drosophila LMO protein (dLMO), Beadex (Bx), regulates various developmental processes like wing margin development and bristle development. It also regulates Drosophila behavior in response to cocaine and ethanol. We have previously generated Bx null flies and shown its essential function in neurons for multiple aspects of female reproduction. However, it was not known whether Bx affects reproduction through its independent function in ovaries. In this paper we show that female flies null for Bx lay eggs with multiple defects. Further, through knock down studies we demonstrate that function of Bx in follicle cells is required for normal egg development. We also show that function of Bx is particularly required in border cells for Drosophila fertility. PMID- 29580688 TI - SIRT3 aggravates metformin-induced energy stress and apoptosis in ovarian cancer cells. AB - Increasing evidence suggests that mitochondrial respiratory chain complex I participates in carcinogenesis and cancer progression by providing energy and maintaining mitochondrial function. However, the role of complex I in ovarian cancer is largely unknown. In this study we showed that metformin, considered to be an inhibitor of complex I, simultaneously inhibited cell growth and induced mitochondrial-related apoptosis in human ovarian cancer cells. Metformin interrupted cellular energy metabolism mainly by causing damage to complex I that impacted mitochondrial function. Additionally, treatment with metformin increased the activation of sirtuin 3 (SIRT3), a mitochondrial deacetylase. We demonstrated that SIRT3 overexpression aggravated metformin-induced apoptosis, energy stress and mitochondrial dysfunction. Moreover, treatment with metformin or SIRT3 overexpression increased activation of AMP-activated protein kinase (AMPK), a major sensor of cellular energy status. AMPK compensated for energy loss by increasing glycolysis. The impact of this was assessed by reducing glucose levels in the media or by using inhibitors (2-deoxyglucose, Compound C) of glycolysis and AMPK. The combination of these factors with metformin intensified cytotoxicity through further downregulation of ATP. Our study outlines an important role for SIRT3 in the antitumor effect of mitochondrial complex I inhibitors in human ovarian cancer cells. This effect appears to be mediated by induction of energy stress and apoptosis. Strategies that target the mitochondria could be enhanced by modulating glycolysis to further aggravate energy stress that may increase the antitumor effect. PMID- 29580689 TI - Relationships between scalp, brain, and skull motion estimated using magnetic resonance elastography. AB - The objective of this study was to characterize the relationships between motion in the scalp, skull, and brain. In vivo estimates of motion transmission from the skull to the brain may illuminate the mechanics of traumatic brain injury. Because of challenges in directly sensing skull motion, it is useful to know how well motion of soft tissue of the head, i.e., the scalp, can approximate skull motion or predict brain tissue deformation. In this study, motion of the scalp and brain were measured using magnetic resonance elastography (MRE) and separated into components due to rigid-body displacement and dynamic deformation. Displacement estimates in the scalp were calculated using low motion-encoding gradient strength in order to reduce "phase wrapping" (an ambiguity in displacement estimates caused by the 2 pi-periodicity of MRE phase contrast). MRE estimates of scalp and brain motion were compared to skull motion estimated from three tri-axial accelerometers. Comparison of the relative amplitudes and phases of harmonic motion in the scalp, skull, and brain of six human subjects indicate that data from scalp-based sensors should be used with caution to estimate skull kinematics, but that fairly consistent relationships exist between scalp, skull, and brain motion. In addition, the measured amplitude and phase relationships of scalp, skull, and brain can be used to evaluate and improve mathematical models of head biomechanics. PMID- 29580691 TI - Measurement of active muscle stiffness with and without the stretch reflex. AB - The purpose of the present study was to evaluate active muscle stiffness with the stretch reflex according to changes (in 110-ms period after stretching) in torque and fascicle length during slower angular velocity (peak angular velocity of 100 deg.s-1) in comparison with active muscle stiffness without the stretch reflex (in 60-ms period after stretching) during slower and faster (peak angular velocity of 250 deg.s-1) angular velocities. Active muscle stiffness in the medial gastrocnemius muscle was calculated according to changes in estimated muscle force and fascicle length with slower and faster stretching during submaximal isometric contractions (10-90% maximal voluntary contractions). Active muscle stiffness significantly increased for both angular velocities and analyzed periods as torque levels exerted became higher. The effects of angular velocities and the interaction between angular velocities and torque levels were not significantly different between 250 deg.s-1 (in 60-ms period after stretching) and 100 deg.s-1 (in 110-ms period after stretching) conditions. The effects of the analyzed periods and the interaction between analyzed periods and torque levels were not significantly different between the analyzed periods (60-ms and 110-ms periods after stretching) for the 100 deg.s-1 condition. Furthermore, active muscle stiffness measured during the same angular velocity had significant correlations between those calculated in the different analyzed periods, whereas those under 250 deg.s-1 (60-ms period after stretching) did not correlate with those under 100 deg.s-1 (110-ms period after stretching). These results suggest that active muscle stiffness is not influenced by the stretch reflex. PMID- 29580690 TI - Opto-mechanical characterization of sclera by polarization sensitive optical coherence tomography. AB - Polarization sensitive optical coherence tomography (PSOCT) is an interferometric technique sensitive to birefringence. Since mechanical loading alters the orientation of birefringent collagen fibrils, we asked if PSOCT can be used to measure local mechanical properties of sclera. Infrared (1300 nm) PSOCT was performed during uniaxial tensile loading of fresh scleral specimens of rabbits, cows, and humans from limbal, equatorial, and peripapillary regions. Specimens from 8 human eyes were obtained. Specimens were stretched to failure at 0.01 mm/s constant rate under physiological conditions of temperature and humidity while birefringence was computed every 117 ms from cross-sectional PSOCT. Birefringence modulus (BM) was defined as the rate of birefringence change with strain, and tensile modulus (TM) as the rate of stress change between 0 and 9% strain. In cow and rabbit, BM and TM were positively correlated with slopes of 0.17 and 0.10 GPa, and with correlation coefficients 0.63 and 0.64 (P < 0.05), respectively, following stress-optic coefficients 4.69, and 4.20 GPa-1. In human sclera, BM and TM were also positively correlated with slopes of 0.24 GPa for the limbal, 0.26 GPa for the equatorial, and 0.31 GPa for the peripapillary regions. Pearson correlation coefficients were significant at 0.51, 0.58, and 0.69 for each region, respectively (<0.001). Mean BM decreased proportionately to TM from the limbal to equatorial to peripapillary regions, as stress-optic coefficients were estimated as 2.19, 2.42, and 4.59 GPa-1, respectively. Since birefringence and tensile elastic moduli correlate differently in cow, rabbit, and various regions of human sclera, it might be possible to mechanically characterize the sclera in vivo using PSOCT. PMID- 29580692 TI - Modeling the two-dimensional accuracy of soccer kicks. AB - In many sports, athletes perform motor tasks that simultaneously require both speed and accuracy for success, such as kicking a ball. Because of the biomechanical trade-off between speed and accuracy, athletes must balance these competing demands. Modelling the optimal compromise between speed and accuracy requires one to quantifyhow task speed affects the dispersion around a target, a level of experimental detail not previously addressed. Using soccer penalties as a system, we measured two-dimensional kicking error over a range of speeds, target heights, and kicking techniques. Twenty experienced soccer players executed a total of 8466 kicks at two targets (high and low). Players kicked with the side of their foot or the instep at ball speeds ranging from 40% to 100% of their maximum. The inaccuracy of kicks was measured in horizontal and vertical dimensions. For both horizontal and vertical inaccuracy, variance increased as a power function of speed, whose parameter values depended on the combination of kicking technique and target height. Kicking precision was greater when aiming at a low target compared to a high target. Side-foot kicks were more accurate than instep kicks. The centre of the dispersion of shots shifted as a function of speed. An analysis of the covariance between horizontal and vertical error revealed right-footed kickers tended to miss below and to the left of the target or above and to the right, while left-footed kickers tended along the reflected axis. Our analysis provides relationships needed to model the optimal strategy for penalty kickers. PMID- 29580693 TI - Innovative in cellulo method as an alternative to in vivo neurovirulence test for the characterization and quality control of human live Yellow Fever virus vaccines: A pilot study. AB - Live attenuated vaccines have proved to be mostly valuable in the prevention of infectious diseases in humans, especially in developing countries. The safety and potency of vaccine, and the consistency of vaccine batch-to-batch manufacturing, must be proven before being administrated to humans. For now, the tests used to control vaccine safety largely involve animal testing. For live viral vaccines, regulations require suppliers to demonstrate the absence of neurovirulence in animals, principally in non-human primates and mice. In a search to reduce the use of animals and embracing the 3Rs principles (Replacement, Reduction, Refinement in the use of laboratory animals), we developed a new Blood-Brain Barrier Minibrain (BBB-Minibrain) in cellulo device to evaluate the neuroinvasiveness/neurovirulence of live Yellow Fever virus (YFV) vaccines. A pilot study was performed using the features of two distinct YFV strains, with the ultimate goal of proposing a companion test to characterize YFV neurovirulence. Here, we demonstrate that the BBB-Minibrain model is a promising alternative to consider for future replacement of YFV vaccine in vivo neurovirulence testing (see graphical abstract).

AB - BACKGROUND: There is a paucity of data on the utility of right atrial pressure (RAP) for estimating pulmonary capillary wedge pressure (PCWP) in patients with normal ejection fraction (EF), including patients with heart failure with preserved EF. METHODS: Mean RAP was compared with PCWP in 129 patients (mean age, 61 +/- 11 years; 45% men) with exertional dyspnea enrolled in a multicenter study. Measurements included left ventricular volumes, EF, and mitral inflow velocities. RESULTS: Mean PCWP was 14 +/- 7 mm Hg, and mean RAP was 8 +/- 5 mm Hg. A significant relation was present between mean RAP and mean PCWP (r2 = 0.5, P < .001). RAP > 8 mm Hg had 76% sensitivity and 86% specificity in detecting mean PCWP > 12 mm Hg. In 101 patients with inconclusive mitral filling pattern (defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging 2016 diastolic function recommendations), RAP by catheterization had sensitivity of 73% and specificity of 91%. In a subset of 59 patients with echocardiographic assessment of mean RAP, RAP by echocardiography had sensitivity of 76% and specificity of 89%. CONCLUSIONS: Mean RAP provides useful information about mean PCWP in many patients with normal left ventricular EF. There is good sensitivity and excellent specificity when combining invasive or noninvasive RAP and mitral velocities to determine if PCWP is elevated. PMID- 29580695 TI - Vasodilator Stress Single-Photon Emission Computed Tomography or Contrast Stress Echocardiography Association with Hard Cardiac Events in Suspected Coronary Artery Disease. AB - BACKGROUND: We compared the long-term outcome of subjects without prior cardiac disease who underwent either vasodilator single-photon emission computed tomography (SPECT) or contrast stress-echocardiography (cSE) for suspected coronary artery disease (CAD). METHODS: Subjects who underwent vasodilator SPECT or cSE between 2008 and 2012 for suspected CAD but no history of cardiac disease were included. We retrospectively compared the association of each method with combined all-cause death and nonfatal myocardial infarction and their positive predictive value (PPV) for angiographically obstructive CAD. RESULTS: A total of 1,387 subjects were selected: 497 who underwent SPECT and 890 who underwent cSE. During 4 years of mean follow-up there were 78 hard events in the cSE group and 51 in the SPECT group. Event-free survival in subjects testing positive for ischemia, either with SPECT or cSE, was significantly worse both in the overall population and after propensity matching patients. In multivariable analyses, vasodilator SPECT or cSE demonstrated significant stratification capability with an ischemic test doubling (SPECT) or more than doubling (cSE) the risk of future hard events independently from other variables. PPV of vasodilator SPECT for the diagnosis of obstructive CAD was inferior to vasodilator cSE (PPV = 63% vs 89%, respectively; P < .001). CONCLUSIONS: Our study suggests that the associations of vasodilator SPECT or cSE with outcome are comparable, with cSE demonstrating better diagnostic PPV for CAD. The absence of ionizing radiation and anticipated lower costs from higher PPV suggest that vasodilator cSE is a valid alternative to vasodilator SPECT as a gatekeeper in subjects without a prior history of CAD. PMID- 29580696 TI - Outcomes in Patients Treated with Post-mastectomy Chest Wall Radiotherapy without the Routine Use of Bolus. AB - AIMS: The use of bolus in post-mastectomy radiotherapy (PMRT) varies significantly between institutions. We report on chest wall recurrence and acute toxicity rates for PMRT patients treated with selective use of bolus. MATERIALS AND METHODS: We analysed PMRT patients who received adjuvant chest wall radiotherapy for invasive breast cancer between 2004 and 2009. Patient, tumour and cancer outcomes were collected from a prospective database, with additional radiotherapy and acute toxicity details supplemented retrospectively. Chest wall bolus was reserved for patients considered at high risk of local recurrence. RESULTS: There were 314 patients suitable for analysis: 52 received bolus, 262 did not. The mean age was 53.2 years. The median follow-up was 4.2 years. The most common T stage was T2 (37%), followed by T3/T4 (33%). There were 229 patients (73%) who had N+ disease; 213 (68%) patients had grade 3 cancer. Oestrogen receptor was positive in 176 (56%) cases, progesterone receptor was positive in 134 (43%) and HER2 receptor was positive in 24 (8%). Lymphovascular space invasion was present in 146 patients (46%), dermal invasion in 30 patients (10%) and positive margin in 14 patients (4%). The 4 year chest wall recurrence rate was 14% (95% confidence interval 5.4-26.8%) in the bolus group and only 3.5% (95% confidence interval 1.6-6.4%) in the non-bolus group. On univariate analysis, use of bolus was associated with a significant difference in chest wall recurrence (hazard ratio 3.09; 1.15-8.33; P = 0.025). However, when taking into account margin status, this significance was lost (hazard ratio = 2.45; 95% confidence interval 0.80-7.50, P = 0.12). There was a higher rate of acute grade 2 skin toxicity in patients receiving bolus compared with those without, 40% versus 21% (P = 0.01). CONCLUSIONS: The selective use of bolus resulted in a small risk of chest wall recurrence rates for low-risk patients. This suggests that the routine use of bolus in PMRT patients may be unnecessary. PMID- 29580697 TI - Intravesical recurrence after bladder sparing treatment of small cell carcinoma of the bladder: Characteristics, treatment, and outcome. AB - INTRODUCTION: Small cell carcinoma of the bladder (SCCB) is a rare and lethal disease. Previously, we and others have reported a bladder sparing strategy with platinum-etoposide-based chemotherapy followed by radiotherapy of the bladder. Little is known on frequency and treatment of intravesical recurrence following this approach. The objective of this study is to describe the incidence of intravesical recurrences and their management. MATERIALS AND METHODS: Retrospective study including all patients with SCCB treated at a single institution from 1993 until 2016. All patients with limited disease (LD) SCCB who had a bladder sparing approach with sequential chemotherapy and radiotherapy were identified. Intravesical and overall recurrence rate, overall and disease specific survival, salvage treatment options and their results were retrieved. RESULTS: Of the 110 patients with SCCB (82% male) with a mean age of 65 years and a median follow up of 48 months, 89 patients (81%) had LD-SCCB. Of these, 65 were treated with chemotherapy and radiotherapy, with a median overall recurrence free survival of 22 months (CI: 14-30). Of 65 patients, 23 (35%) progressed to distant metastasis without intravesical recurrence after a median of 9 months (CI: 8-11), whereas 14 patients (22%) developed isolated intravesical recurrence at a median of 24 months (CI: 14-34). Local recurrence contained SCCB, urothelial carcinoma, and carcinoma in situ and was treated with various local salvage treatments including TURB, cystectomy, neoadjuvant chemotherapy, and BCG. Following salvage treatment a complete response was seen in 64%. Median overall survival for intravesical vs. systemic recurrence was different, with 28 (CI: 9-47) and 8 (CI: 5-11) months, respectively (P<0.001). CONCLUSION: SCCB is a serious potentially lethal disease. Even in patients with LD-SCCB a high percentage rapidly develops systemic disease. This suggests that systemic therapy is more important than the type of local treatment to control the disease but small sample sizes limit the ability to distinguish between different treatment options in this study. A bladder sparing approach can be a reasonable alternative to major surgery. However, in those surviving long enough isolated intravesical recurrence occurs even after many years. Our results indicate that long term follow up is required because salvage therapy can be successful in the majority of patients. PMID- 29580698 TI - Application of HRAM screening and LC-MS/MS confirmation of active pharmaceutical ingredient in "natural" herbal supplements. AB - The growing market of herbal remedies worldwide could pose severe problems to consumers' health due to the possible presence of potentially harmful, undeclared synthetic substances or analogues of prescription drugs. The present work shows a simple but effective approach to unequivocally identify synthetic anorectic compounds in allegedly 'natural' herbal extracts, by exploiting liquid chromatography/time of flight (Q-TOF LC/MS) technology coupled to liquid chromatography/triple quadrupole (LC-MS/MS) confirmation and quantitation. The procedure was applied to five tea herbal extracts and pills sold as coadjutant for weigh loss. The method exploited liquid-liquid sample extraction (LLE) and separation in a C18 (2.1mm*150mm, 1.8MUm) column. QTOF acquisitions were carried out both in scan mode and all ion MS/MS mode and results were obtained after search against ad hoc prepared library. Sibutramine, 4-hydroxyamphetamine, caffeine and theophylline were preliminary identified samples. Confirmation and quantitation of the preliminary identified compounds were obtained in LC-MS/MS after preparation of appropriated standards. Sibutramine, caffeine and theophylline were finally confirmed and quantitate. PMID- 29580699 TI - Evaluation of two commercial methods for the susceptibility testing of Candida species: Vitek 2(r) and Sensititre YeastOne(r). AB - BACKGROUND: An increased incidence of fungal infections caused by Candida species, especially Candida glabrata and Candida krusei, which are less susceptible to azoles, has been observed. Standardized susceptibility testing is essential for clinical management and for monitoring the epidemiology of resistance. AIMS: We evaluated the performance of two different susceptibility testing commercial methods, Vitek 2(r) and Sensititre YeastOne(r), and compared them with the standard broth microdilution method (CLSI). METHODS: A total of 80 isolates of several Candida species (Candida albicans, Candida parapsilosis complex, Candida tropicalis, C. glabrata and C. krusei) were selected for this study. RESULTS: We analyzed the categorical agreement (CA) between the methods, stratifying the disagreements. The average CA between the methods was 96.3% for Vitek 2(r) and 84% for Sensititre YeastOne(r). No very major errors were observed. Major errors and minor errors were found for all the isolates tested. With the azoles, both Vitek 2(r) and Sensititre YeastOne(r) had good and similar performance levels, except for C. tropicalis and C. krusei (Sensititre YeastOne(r) showed low CA, 56.2%). With the echinocandins, both methods showed good performance for C. albicans, C. parapsilosis and C. tropicalis. However, we observed important discrepancies for C. krusei with caspofungin: Vitek 2(r) had 100% CA while Sensititre YeastOne(r) had only 25%. With amphotericin B, both Vitek 2(r) and Sensititre YeastOne(r) had good performance with high CA. CONCLUSIONS: Despite the limited isolates tested, we concluded that both methods have good performance and are reliable for antifungal susceptibility testing. However, caspofungin activity against C. krusei and C. glabrata should be interpreted carefully when using Sensititre YeastOne(r) because we observed a low CA. PMID- 29580700 TI - [Peer support programs in mental health in France: Status report and challenges]. AB - OBJECTIVES: Recovery is a process through which people experiencing mental illness learn to live with their disorder and reach social insertion and citizenship. This positive approach focuses on a person's competencies and strengths rather than on the symptoms. Within this philosophy, peer support has been unevenly developing in mental health services worldwide with roots in the South-American social programs for homeless people and in the American recovery circles in the field of addiction. Therapeutic efficiency of peer support has been proven by several studies including a control group, as being at least as good as traditional services and even better in some specific areas such as reduction of need for emergency services and ability to reach "difficult" patients. The integration of former psychiatric services users in mental health services can take several forms, from the participation to scientific research studies to the direct involvement in a professional team at mental health facilities. In this context, our research aims to sum up the situation in France in comparison with other countries. METHODS: We conducted a worldwide literature review in English and in French on peer support experiences and policies in mental health services, using medical and psychological databases (PsycInfo, PsycArticles, SantePsy, Cairn, Medline, Wiley Interscience and PubPsych) on a recent period: 2005-2016. In total, 32 relevant scientific papers have been included in our research. In some cases, we have also used official reports, blogs, Internet sites, and mass media articles when they were relevant. RESULTS: Our results show that this movement has been long to develop in France, with controversies having been raised since the beginning on the role that peers should play and confusion with existing social integration programs in the associative sector. Drawing inspiration from the Canadian model, a recent "peer mentor" initiative has been analyzed after 2 years of existence: many benefits for services users such as the optional aspect of this care process, a more authentic therapeutic relationship, a less normative frame, an active partnership, and a more optimistic philosophy aiming to make "small steps" towards improvement have been reported. Health professionals and peer mentors themselves have found benefits during the process. However, several limits such as difficulties to find a place with regards to the psychiatric team and difficulties to take advantage of the peer specificity, resulting in a significant attrition of the number of peer mentors, could be observed. A few other important initiatives focused on social insertion and using the help of professional peer support have been developed in recent years, but they seem to have encountered the same issues about positioning themselves both in terms of day-to-day integration in the professional environment and in the job title given by institutions which rarely corresponds to their experience and specificity. In addition, it remains difficult to obtain reliable information, as only a few papers have been published on this matter. Also, while some evaluation studies are currently being carried out, independent quantitative studies of the few running programs seem to lack in this field. CONCLUSIONS: In our presentation, taking into account the difficulties that were raised in French programs and the lessons of practical experiences at work in other countries, we propose recommendations for larger and more effective implementations of peer support programs in France. As this new kind of care is emerging and seems promising in terms of benefits for not only the users but also the peer supporters and the teams of health professionals, we also insist on the need for a systematic scientific and objective evaluation of the programs. PMID- 29580701 TI - Facial emotion recognition in children with or without Attention Deficit/Hyperactivity Disorder: Impact of comorbidity. AB - OBJECTIVES: This study sought to assess facial emotion recognition deficit in children with Attention Deficit/Hyperactivity Disorder (ADHD) and to test the hypothesis that it is increased by comorbid features. METHOD: Forty children diagnosed with ADHD were compared with 40 typically developing children, all aged from 7 to 11years old, on a computerized facial emotion recognition task (based on the Pictures of Facial Affect). Data from parents' ratings of ADHD and comorbid symptoms (on the Conners' Revised Parent Rating Scale) were also collected. RESULTS: Children with ADHD had significantly fewer correct answer scores than typically developing controls on the emotional task while they performed similarly on the control task. Recognition of sadness was especially impaired in children with ADHD. While ADHD symptoms were slightly related to facial emotion recognition deficit, oppositional symptoms were related to a decrease in the number of correct answers on sadness and surprise recognition. CONCLUSION: Facial emotion recognition deficit in children with ADHD might be related to an impaired emotional process during childhood. Moreover, Oppositional Defiant Disorder seems to be a risk factor for difficulties in emotion recognition especially in children with ADHD. PMID- 29580702 TI - [Methods to improve suicidal adolescents' compliance to care after emergency discharge: A literature review]. AB - OBJECTIVES: Suicidal adolescents admitted in an Emergency Department (ED) present a high risk of suicidal reattempts. Poor observance of follow-up in this particular group imped the efficacity of the treatment. We propose to summarize the international literature on ED interventions promoting suicidal adolescents' adherence to care. METHOD: We carried out a comprehensive review of papers listed in PubMed, PsycInfo, and CINHAL databases using keywords about adolescence, suicide, and ED. We also manually consulted the main journals specialized in suicidology (Crisis and Suicide and Life-Threatening Behavior) and adolescence (Journal of the American Academy of Child and Adolescent Psychiatry, Journal of Adolescent Health, Neuropsychiatrie de l'Enfance et de l'Adolescence). We selected the relevant articles describing or evaluating one or more interventions initiated in the ED and designed to promote adolescent adherence to post emergency care. The results are presented in a narrative review form. RESULTS: Interventions are organized in three groups: interventions that take place solely at the ED (problem-solving interventions and educational interventions directed to families) and interventions that take place during and after emergency care (we included in this group the ED-Care program, the FISP program, and the SAFETY program), to which should be added interventions that take place prior to care, in particular specific trainings for medical and paramedical teams. Small samples and barriers in measuring adherence to care make statistical comparisons difficult, yet the interventions that seem most effective are those that target the time both during and after ED discharge, those which are implemented most rapidly after discharge, those which actively include parents, and those which involve an implication of the families about barriers to follow-up. CONCLUSION: Our results show an effectiveness of complete programs on short-term compliance but no conclusion can be drawn on long-term effects. Most comprehensive care programs are based on the principle of adolescent compliance, which remains problematic. Until today, no ideal protocol exists to improve short-term as well as long-term compliance to care among adolescents after a suicide attempt. We have to improve our understanding of facilitators and barriers to follow-up using quantitative as well as qualitative research studies. Although it is well established that parents' involvement in the early stages of care is essential, little is known about the underlying processes. In these situations, qualitative studies could help to better target interventions that lead more particularly to follow up compliance in adolescence. PMID- 29580703 TI - [Delusional misidentification syndromes: A factor associated with violence? Literature review of case reports]. AB - OBJECTIVES: Delusional misidentification syndromes (DMS) correspond to the delusional belief of misidentification of familiar persons, places or objects and to the conviction that they have been replaced or transformed. Several cases of patients who developed violent behavior while suffering from DMS have been published. This led some authors to consider patients with DMS at risk of violence. However, only a few studies have focused on the potential relationship between violence and DMS. The aim of our study was to explore this relationship with a literature review of published cases of patients having committed violent acts associated to DMS. METHODS: A systematic literature search was conducted on PubMed up to January 2017 using the following term combination "misidentification" and "violence" Fifteen cases of patients with DMS who had committed violent acts were identified. The data from these descriptions were analyzed and synthetized. RESULTS: Most of the patients were men with a diagnosis of schizophrenia and Capgras syndrome. Acts of violence were severe with a relatively high number of murders or attempted murders. For half of the patients these violent acts were perpetrated with weapons. Victims were regularly the patient's family members and the assaults were usually not planned. Delusional syndromes often progressed for several years. Importantly, substance abuse, which is known to increase the risk of violence in patients with schizophrenia, was only observed in two patients. CONCLUSION: DMS are associated with several risk factors of violence, such as a diagnosis of schizophrenia, specific delusions including megalomania, persecution, negative affects and identified targets. Despite this risk for severe violence, there are no existing guidelines on how to assess and treat DMS in schizophrenia. Accordingly, we propose (1) the establishment of formal diagnostic criteria, (2) the development of rigorous research on these syndromes and (3) the integration of DMS in assessment of violence risk in schizophrenic patients. PMID- 29580704 TI - On cognitive debiasing and the judgment of suicide-attackers. AB - Suicide-attacks are possibly increasing in frequency all over the world. To date, these attacks are not considered as a manifestation of a particular mental illness. However, the process of radicalization of suicide-attackers has to interest the field of mental health. One plausible explanation for the radicalization of individuals is the use of biased cognitive schemes by the indoctrinator. Among these cognitive schemes could figure the causal attribution bias in which the subject cannot distinguish in front of two factors that operate simultaneously, the share of each factor in achieving a certain goal. Another cognitive bias would be the confirmation bias during which the subject would tend to adhere to ideas from his/her own thinking or the thinking of subjects who share some cultural values with him/her and refute any other ideas. Finally, the bias of polarization or splitting could also be incriminated. Through this bias, the subject would either be proud of being a member of a cultural group or ashamed when he/she feels that this group is being attacked and that he/she is unable to rescue it. Approaches to increase the awareness of individuals to the adverse effects of these biased cognitive schemes may theoretically reduce the risk of committing suicide-attacks. However, despite numerous attempts of "deradicalization" involving technological means of communication as well as social "reintegration" centers, all approaches aiming at raising awareness of cognitive biases need to be studied in a scientific manner before they become widespread. PMID- 29580705 TI - [Consultation/liaison addiction medicine: Tools and specificities]. AB - Since the 1970s, the concept of "consultation/liaison (CL) psychiatry" has pertained to specialized mobile teams which meet inpatients hospitalized in non psychiatric settings to offer them on-the-spot psychiatric assessment, treatment, and, if needed, adequate referral. Since the birth of CL psychiatry, a long set of theoretical books and articles has aimed at integrating CL psychiatry into the wider scope of psychosomatic medicine. In the year 2000, a circular issued by the Health Ministry defined the organization of "CL addiction services" in France. Official CL addiction teams are named "Equipes de Liaison et de Soins en Addictologie" (ELSAs) which are separated from CL psychiatry units. Though this separation can be questioned, it actually emphasizes that the work provided by CL addiction teams has some very specific features. The daily practice of ELSAs somewhat differs from that of psychiatric CL teams. Addictive behaviors often result from progressive substance misuse. In this respect, the ELSAs' practice frequently involves screening, brief intervention, and referral to treatment (SBIRT) interventions, which are rather specific of addiction medicine and consist more of prevention interventions than actual addiction treatment. Moreover, for patients with characterized substance use disorders substantial skills in motivational interviewing are required in ELSA consultations. Though motivational interviewing is not specific to addiction medicine, its regular use is uncommon for other liaison teams in France. Furthermore, substance misuse can induce many types of acute or delayed substance-specific medical consequences. These consequences are often poorly known and thus poorly explored by physicians of other specialties. ELSAs have therefore the role of advising their colleagues for a personalized somatic screening among patients with substance misuse. In this respect, the service undertaken by ELSAs is not only based on relational skills but also comprises a somatic expertise. This specificity differs from CL psychiatry. Moreover, several recent studies have shown that in some cases it was useful to extend liaison interventions for addiction into outpatient consultations that are directly integrated in the consultation units of certain specialties (e.g., hepatology, emergency, or oncology). Such a partnership can substantially enhance patients' motivation and addiction outcome. This specificity is also hardly transposable in CL psychiatry. In France, addiction medicine is an inter-specialty that is not fully-integrated into psychiatry. This separation is also applied for CL services which emphasizes real differences in the daily practices and in intervention frameworks. Regardless, CL psychiatry units and ELSAs share many other features and exhibit important overlaps in terms of targeted populations and overall missions. These overlaps are important to conjointly address, with the aim to offer integrated and collaborative services, within the hospital settings of other medical specialties. PMID- 29580706 TI - [Predictive factors of seclusion duration in patients hospitalized in psychiatry settings. A prospective multisite study in the DTRF Paris-Sud]. AB - INTRODUCTION: In psychiatric inpatient settings seclusion is a last resort to ensure the safety of the patient, other patients, and staff from disturbed behaviors. Despite its major interest for patients, seclusion could negatively impact treatment adherence and patient/staff relationships. Indeed, some secluded patients report a feeling of guilt during the measure and do not consider seclusion to be a healthcare intervention. To be more beneficial and to reduce the feeling by patients of being forced, seclusions should be as short and rare as possible. In other words, measures to reduce seclusion are available and have been clearly identified. Such measures could be applied, in the first instance, in patients with longer duration. In this way, the aim of this study was to investigate predictive factors of a seclusion of long duration. METHODS: Our study was based on the dataset of the EPIC study, an observational prospective French multicenter study of seclusion and restraint. The EPIC study occurred in seven French psychiatric hospitals in the southern region of Paris. Inclusions were realized for 73days and allowed a data collection of 302 seclusion measures. Of these measures 236 were effectively a seclusion in a standardized room. Because the median duration was 7days, we defined two groups of patients: duration<7days and duration >= 7 days. Our variable to be explicated was duration >= 7 days. Explicative variables available in EPIC study were age, sex, forced hospitalization, autoagressivity, heteroagressivity, use of sedative treatment (oral or intramuscular), history of seclusion and patient diagnoses. We used bivariate and multivariate analyses to explore the association between a seclusion duration >= 7 days and explicative variables. Diagnoses were classified as psychotic disorders, mood disorders and others diagnoses. To be included in multivariate logistic regressions, diagnoses were treated as dummy variables (mood disorder vs psychotic disorders; psychotic disorders vs others; mood disorders vs others). Statistical analyses were performed using SPSS software 20.0 and R 3.4.0. RESULTS: Of the 236 measures of seclusion the mean age was 38.2 (+/-12.8), 196 (83%) patients were forcibly hospitalized prior to their seclusion, 147 (62%) had a diagnosis of psychotic disorder, 43 (18%) a diagnosis of mood disorder and 33 (14%) an "other diagnosis". Mean duration was 10.2 (1.5) days and median was 7.1 days. One hundred and thirty-five (47%) patients were in the group of duration >= 7 days. In bivariate analyses, variables associated with a duration >= 7 days were: being in forced hospitalization prior to the seclusion (P=0.04), administration of a sedative treatment (P=0.01) and against the group of others diagnoses the diagnosis of mood disorders (P<0.0005) and psychotic disorders (P=0.001). Multivariate analyses showed that, against the group of other diagnoses, the group of psychotic disorders [OR=3.3, CI 95% (1.3-8.4), P=0.01], the group of mood disorder [OR=2.7, CI 95% (1.4-4.9), P=0.002] and administration of sedative treatment [OR=8.1, CI 95% (2.0-32.5), P=0.003] were significantly associated with a duration >= 7 days. These results were independent from other confusion variables. Considering the hospitalization status, psychotic disorders was the only diagnosis which showed an association between duration >= 7 days and forced hospitalization [OR=2.9 CI 95% (1.1-7.8), P=0.03]. CONCLUSION: Our study highlighted two profiles of higher risk to remain >= 7days in seclusion. The first one is patients with a diagnosis of mood disorder who needed sedative treatment. The second one is patients with a diagnosis of psychotic disorder who needed sedative treatment and forced hospitalized before seclusion. Thus, these two profiles could be a good target to practice, in the first instance, measures to reduce seclusion duration in psychiatry settings. PMID- 29580707 TI - Improving quality of psychiatric care in Latvia by measuring patient experiences. AB - In Latvia, as in many former Soviet Union countries, there used to be little priority given to systematic assessments of the quality of psychiatric care. Furthermore, using the experiences of patients as a measure of quality was unthinkable because psychiatric patients were seen as incapable of assessing quality of psychiatric services. Over the past few years, and facilitated by Latvia's progress along the route of Western democracy and participation in international organizations (EU, OECD), as well as funding support from the EU, several policy documents have been developed with the aim of improving healthcare quality. Simultaneously, several small-scale initiatives have emerged aiming at the promotion of quality of care, such as the quality award, and the quality comparison of psychiatric hospitals. Furthermore, the Psychiatric Inpatient Patient Experience Questionnaire for on-site measurement (PIPEQ-OS) has recently been adapted for use in Latvia. The first application of PIPEQ-OS in a psychiatric hospital in Riga reveals high patient responsiveness, interest and surprise about being asked to participate in the decision-making process regarding treatment and pharmaceutical choices. More widespread use of the PIPEQ OS has considerable potential for (1) improving information about treatment shortcomings from the patients' perspective and (2) improving the treatment process by opening doors of cooperation with patients and changing deep-rooted paradigms.

PMID- 29580709 TI - Impact of Surgical Factors on Robotic Partial Nephrectomy Outcomes: Comprehensive Systematic Review and Meta-Analysis. AB - PURPOSE: Utilization of robotic partial nephrectomy has increased significantly. We report a literature wide systematic review and cumulative meta-analysis to critically evaluate the impact of surgical factors on the operative, perioperative, functional, oncologic and survival outcomes in patients undergoing robotic partial nephrectomy. MATERIALS AND METHODS: All English language publications on robotic partial nephrectomy comparing various surgical approaches were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement and AHRQ (Agency for Healthcare Research and Quality) guidelines to evaluate PubMed(r), Scopus(r) and Web of ScienceTM databases (January 1, 2000 to October 31, 2016, updated June 2017). Weighted mean difference and odds ratio were used to compare continuous and dichotomous variables, respectively. Sensitivity analyses were performed as needed. To condense the sheer volume of analyses, for the first time data are presented using novel summary forest plots. The study was registered at PROSPERO (https://www.crd.york.ac.uk/prospero/, ID CRD42017062712). RESULTS: Our meta analysis included 20,282 patients. When open partial nephrectomy was compared to robotic partial nephrectomy, the latter was superior for blood loss (weighted mean difference 85.01, p <0.00001), transfusions (OR 1.81, p <0.001), complications (OR 1.87, p <0.00001), hospital stay (weighted mean difference 2.26, p = 0.001), readmissions (OR 2.58, p = 0.005), percentage reduction of latest estimated glomerular filtration rate (weighted mean difference 0.37, p = 0.04), overall mortality (OR 4.45, p <0.0001) and recurrence rate (OR 5.14, p <0.00001). Sensitivity analyses adjusting for baseline disparities revealed similar findings. When robotic partial nephrectomy was compared to laparoscopic partial nephrectomy, the former was superior for ischemia time (weighted mean difference 4.21, p <0.0001), conversion rate (OR 2.61, p = 0.002), intraoperative (OR 2.05, p >0.0001) and postoperative complications (OR 1.27, p = 0.0003), positive margins (OR 2.01, p <0.0001), percentage decrease of latest estimated glomerular filtration rate (weighted mean difference -1.97, p = 0.02) and overall mortality (OR 2.98, p = 0.04). Hilar control techniques, selective and unclamped, are effective alternatives to clamped robotic partial nephrectomy. An important limitation is the overall suboptimal level of evidence of publications in the field of robotic partial nephrectomy. No level I prospective randomized data are available. Oxford level of evidence was level II, III and IV in 5%, 74% and 21% of publications, respectively. No study has indexed functional outcomes against volume of parenchyma preserved. CONCLUSIONS: Based on the contemporary literature, our comprehensive meta-analysis indicates that robotic partial nephrectomy delivers mostly superior, and at a minimum equivalent, outcomes compared to open and laparoscopic partial nephrectomy.

AB - OBJECTIVE: Anti-NMDA receptor encephalitis (NMDARE) may not respond to first line immunotherapy. Biomarkers to track disease course and guide escalation of immunotherapy are needed. We describe the evolution of EEG in four patients with NMDARE requiring prolonged intensive care. METHODS: Within a database of 121 patients with immune-mediated neurological disorders, ten with NMDARE were retrospectively identified. Four patients did not respond to first line immunotherapy. Continuous EEG was reviewed and correlated with clinical status and treatment. RESULTS: Intermittent polymorphic delta slowing was present in all patients. Generalized rhythmic delta occupied increasing proportion of the EEG as disease progressed, at times with superimposed beta. The institution of second line immunotherapy was followed by progressive decrease in rhythmic delta, predating clinical improvement. In one patient who did not respond to second line immunotherapy, rhythmic delta continued to occupy a majority of the recording. The extreme delta pattern was not seen in a comparison cohort of patients with autoimmune encephalitis without anti-NMDA-R antibodies. CONCLUSIONS: Extreme delta, with or without brushes, increases with progression of NMDARE, responds to escalation of immunotherapy, predating clinical improvement, and is likely specific to NMDA-R antibodies. SIGNIFICANCE: Extreme delta may be a surrogate marker of disease activity in NMDARE refractory to first line immunotherapy. PMID- 29580711 TI - Clinical Outcomes after Pulmonary Cryoablation with the Use of a Triple Freeze Protocol. AB - PURPOSE: To elucidate clinical variables associated with safety and efficacy in patients after cryoablation of pulmonary tumors with the use of a triple freeze protocol. MATERIALS AND METHODS: Percutaneous cryoablation of pulmonary tumors was performed using Galil Medical cryoprobes (Arden Hills, Minnesota) with a triple freeze protocol: 67 nodules in 42 patients were treated at a single institution from 2012 to 2016. Average nodule diameter was 1.6 cm (range 0.4 5.9); 13 nodules (19.4%) were pathologically determined to be a primary lung malignancy, whereas 54 (80.6%) were metastatic nodules of extrapulmonary origin. Average patient age was 68.1 years (range 39.6-89.6), and the male-female ratio was 1.3:1. Ipsilateral thoracic surgery, intervention, or radiotherapy had been performed before the first cryoablation in 18 patients (42.9%). Mean imaging follow-up was 326 days (range 9-1,152). RESULTS: Pneumothorax occurred in 19 cases (33.9%), 7 (12.5%) requiring chest tube, the likelihood of which was significantly greater in patients with 3 or more cryoprobes (P < .01). Local tumor recurrence/residual disease occurred in 6 cases (9.0%). Local tumor recurrence was not seen after ablation of nodules measuring <1.0 cm at the time of procedure, a significant difference from the recurrence ratee of 14.3% for nodules measuring >=1.0 cm (P < .05). Likelihood of tumor recurrence/residual disease did not correlate with tumor pathology, tumor location, or procedural factors. The estimated marginal probabilities of local recurrence were 11.4%, 11.4%, and 38.1% at 1, 2, and 3 years after ablation, respectively. CONCLUSIONS: Cryoablation of pulmonary tumors with the use of a triple freeze protocol is a viable modality with low recurrence and complication rates. PMID- 29580712 TI - Prostatic Artery Embolization in the Treatment of Localized Prostate Cancer: A Bicentric Prospective Proof-of-Concept Study of 12 Patients. AB - PURPOSE: To provide initial data on tumoricidal efficacy of embolization on prostate cancer via histopathologic examination of prostatectomy specimens after embolization. MATERIALS AND METHODS: In this bicentric prospective trial, 12 men with localized prostate cancer underwent radical prostatectomy 6 weeks after prostatic artery embolization (PAE) from October 2016 to May 2017. PAE was performed with the use of 100-MUm Embozene microspheres (Boston Scientific, Natick, Massachusetts). Response of prostate cancer tissue to PAE was assessed according to tumor regression grades. The major outcome measure was complete histopathologic absence of viable cancer cells, including secondary foci, in the prostatectomy specimens. RESULTS: Complete necrosis of the index lesion was found in 2 patients and partial necrosis in 5. Considering secondary cancerous foci, viable cancer cells were found in all 12 patients. Pathologic specimens were characterized by demarcated zones of necrotic tissue predominantly located in the central gland. Two patients required additional surgery to remove necrotic bladder tissue caused by PAE. CONCLUSIONS: PAE with the use of 100-MUm microspheres failed to achieve complete elimination of tumor cells. Extensive tumor regression was induced in some lesions, highlighting the need for further assessment of PAE as a potential treatment option for prostate cancer. PMID- 29580713 TI - Effect of statin therapy on plasma apolipoprotein CIII concentrations: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Statins are well-established low-density lipoprotein cholesterol lowering drugs. Elevated apolipoprotein CIII (Apo CIII) levels are associated with elevated triglyceride-rich particles, which are also considered to be a possible risk factor for cardiovascular disease. OBJECTIVE: The aim of this meta analysis of randomized placebo-controlled clinical trials was to assess the effect of statins on Apo CIII concentrations. METHODS: Randomized placebo controlled trials investigating the impact of statin treatment on cholesterol lowering that include lipoprotein measurement were searched in PubMed, MEDLINE, Scopus, Web of Science, and Google Scholar databases (up to July 31, 2017). A random-effects model and generic inverse variance method were used for quantitative data synthesis. Sensitivity analysis was conducted using the leave one-out method. A weighted random-effects meta-regression was performed to evaluate the impact of potential confounders on Apo CIII concentrations. RESULTS: This meta-analysis of data from 6 randomized placebo-controlled clinical trials (10 statin arms) involving 802 subjects showed that statin therapy significantly decreased circulating Apo CIII concentrations (weighted mean difference [WMD]: 2.71, 95% confidence interval [CI]: -3.74 to -1.68, P < .001; I2: 73.83%). The effect size was robust in the leave-one-out sensitivity analysis and not driven by any single study. Subgroup analysis showed a reduction of Apo CIII concentrations by atorvastatin (WMD: -4.74, 95% CI: -3.74 to -1.68, P = .002; I2: 84.02%), rosuvastatin (WMD: -2.68, 95% CI: -4.52 to -0.84, P = .004; I2: 0%), and lovastatin (WMD: -1.64, 95% CI: -2.22 to -1.07, P < .001; I2: 0%). CONCLUSION: This meta-analysis suggests that statin treatment significantly reduces plasma Apo CIII levels.

PMID- 29580714 TI - Controllable and uncontrollable stress differentially impact pathogenicity and survival in a mouse model of viral encephalitis. AB - Intranasal instillation of vesicular stomatitis virus (VSV) into mice given controllable stress (modeled by escapable foot shock, ES) resulted in enhanced pathogenicity and decreased survival relative to infected mice given uncontrollable stress (modeled by inescapable foot shock, IS) and non-shocked control mice. Survival likely reflected differential cytokine gene expression that may have been regulated by miR146a, a predicted stress-responsive upstream regulator. Controllability also enhanced the accumulation of brain T resident memory cells that persisted long after viral clearance. The unexpected facilitatory effect of ES on antiviral neuroimmune responses and pathogenicity may arise from differential immunoactivating and immunosuppressive effects of uncontrollable and controllable stress.

AB - PURPOSE: Examine recent trends in the use of skeletal radiography and assess the roles of various nonradiologic specialties in the interpretations. METHODS: Medicare Part B fee-for-service claims data files from 2003 to 2015 were analyzed for all Current Procedural Terminology, version 4 (CPT-4) procedure codes related to skeletal radiography. The files provide examination volume, and we calculated utilization rates per 1,000 Medicare beneficiaries. Medicare's physician specialty codes were used to determine the specialties of the providers. Total utilization rate trends were analyzed, as well as those for radiologists and nonradiologists. We determined which nonradiologist specialties were the highest users of skeletal radiography. Medicare place-of-service codes were used to identify the locations where the services were provided. RESULTS: The total utilization rate per 1,000 of skeletal radiography within the Medicare population increased 9.5% from 2003 to 2015. The utilization rate for radiologists increased 5.5% from 2003 to 2015 versus 11.1% for nonradiologists as a group. Among nonradiologist specialties in all health care settings over the study period, orthopedic surgeons increased 10.6%, chiropractors and podiatrists together increased 14.4%, nonphysician providers (primarily nurse practitioners and physician assistants) increased 441%, and primary care physicians' rate decreased 33.5%. Although radiologists do almost all skeletal radiography interpretation in hospital settings, nonradiologists do the majority in private offices. There has been strong growth in skeletal radiography in emergency departments, but a substantial drop in inpatient settings. CONCLUSIONS: The utilization of skeletal radiography has increased more rapidly among nonradiologists than among radiologists. This raises concerns about self-referral and quality. PMID- 29580718 TI - Burden of Illness Associated with Tenosynovial Giant Cell Tumors. AB - PURPOSE: Little is known about the burden of illness in patients with tenosynovial giant cell tumors (TGCT), which are rare, typically benign, lesions of the synovial tissue including giant cell tumor of the tendon sheath (GCT-TS) and pigmented villonodular synovitis (PVNS). The objective of this study was to describe health care resource use and costs for patients with GCT-TS and PVNS, which are rare and typically benign TGCT. METHODS: A retrospective cohort study design was used to analyze administrative claims for adult commercial and Medicare Advantage health plan enrollees with evidence of GCT-TS and PVNS from January 1, 2006 through March 31, 2015. Participants were continuously enrolled for 12 months before (pre-index period) and 12 months after (post-index period) the date of the first tenosynovial giant cell tumor (TGCT) claim (index date). Preindex and postindex measures were compared using the McNemar test and Wilcoxon signed-rank test. Results were stratified by TGCT type. FINDINGS: The study identified 4664 patients with TGCT, 284 with GCT-TS, and 4380 with PVNS. Mean age (GCT-TS group: 50 years; PVNS group: 51 years) and sex distributions (GCT-TS group: 60.2% female; PVNS group: 59.5% female) were similar for each group. Most patients with GCT-TS (78.2%) had at least one postindex surgery, compared with 38.7% of patients with PVNS. Mean total health care costs increased from $8943 in the preindex period to $14,880 in the postindex period (P < 0.001) for GCT-TS and from $13,221 in the preindex period to $17,728 in the postindex period (P < 0.001) for PVNS. Preindex to postindex ambulatory costs increased nearly 120% for patients with GCT-TS ($4340 to $9570, P < 0.001) and 50% for patients with PVNS ($6782 to $10,278, P < 0.001), and physical therapy use increased significantly during the same period (GCT-TS: 18% to 40%, P < 0.001; PVNS: 38% to 60%, P < 0.001). IMPLICATIONS: Costs increased substantially 1 year after the first TGCT claim, with more than half the costs covering ambulatory care. These results suggest a high health care burden once TGCT is identified. PMID- 29580719 TI - The toxicity of E-cigarettes and children's respiratory health. AB - Electronic cigarettes (E-cig), also referred to as Electronic Nicotine Delivery System (ENDS), were initially developed in 2003 to reduce the harmful effects of tobacco smoking. Since then, E-cig have become widely available in many countries and are used by many young people who would be unlikely to take up cigarette smoking. However, the adverse effects on child health remain largely unknown. E cigs are available through regulated sale in many countries, but easily accessible by the internet in others. Adverse effects may be ascribed to the nicotine itself, to the accompanying substances in the aerosol (often referred to as vapour) or to temperature modifications of the content. There is a lack of human studies to assess respiratory effects of nicotine exposure to the unborn or young child. Also assessing the effects of the vaping content apart from nicotine is challenging, with the huge variety of exposure by frequency, duration and content, but experimental studies are on the way that may indicate the level of harm by such products. This article will summarize what is currently known about the use of E-cigs in children and in pregnancy, and discuss adverse effects of direct or in utero exposure to E-cig on the respiratory health of children. We thereby hope to provide a background for discussing potential harms to the respiratory system of children by E-cig exposure in pregnancy and early post natal life, in a setting where an increasing proportion of adolescent and young adults use E-cigs, marketed to be 95% less harmful than conventional cigarettes. PMID- 29580720 TI - [Endonasal endoscopic surgery in pituitary adenomas: Surgical results in a series of 86 consecutive patients]. AB - INTRODUCTION: The endoscopic endonasal approach has become the gold standard for the surgical treatment of pituitary adenomas. OBJECTIVES: The aim of this study is to present the results obtained in our hospital in purely endoscopic surgery of pituitary adenomas. METHODS: From February 2011 to August 2016, we conducted a prospective study on a series of 86 patients with pituitary adenoma, all of whom underwent surgery with a purely endoscopic endonasal approach. The 'four hands two nostrils' technique was performed in all cases by a surgical team composed of an ENT surgeon and a neurosurgeon. Mean follow-up was 32 months. All patients were evaluated according to clinical, radiological and endocrinological criteria. RESULTS: In our series, 53% were women and 47% men. The age ranged from 14 to 84 years of age, with a mean of 54 years of age. The most common initial symptom was visual deficit (42%), followed by hormonal hyperfunction (21%), with acromegaly being the most common clinical syndrome. The most common tumours were non functioning tumours (73%), while GH-secreting tumours (65%) were the most common functioning adenoma. Regarding tumour size, 76% were macroadenomas, 11% microadenomas and 13% giant adenomas. Approximately 63% of the adenomas exhibited suprasellar extension and 37% involved invasion of the cavernous sinus (Knosp grade >=3). Total excision was achieved in 77% of the cases. After the intervention, visual improvement was achieved in 91% and remission of endocrine hyperfunction in up to a 73% of cases. The most common complication was anterior pituitary insufficiency of at least one axis (9%). There were no cases of postoperative cerebrospinal fluid fistula. CONCLUSIONS: In terms of surgical quality, our results are similar to those of published series, and demonstrate the efficacy and safety of the endoscopic endonasal approach as the surgical treatment of choice for pituitary adenomas. However, further studies with a higher sample size are necessary to obtain clinically significant results. PMID- 29580721 TI - Quantitative analysis of hydroxyapatite-binding plasma proteins in genotyped individuals with late-stage age-related macular degeneration. AB - Age-related macular degeneration (AMD) is associated with the formation of sub retinal pigment epithelial (RPE) deposits that block circulatory exchange with the retina. The factors that contribute to deposit formation are not well understood. Recently, we identified the presence of spherular hydroxyapatite (HAP) structures within sub-RPE deposits to which several AMD-associated proteins were bound. This suggested that protein binding to HAP represents a potential mechanism for the retention of proteins in the sub-RPE space. Here we performed quantitative proteomics using Sequential Window Acquisition of all THeoretical fragment-ion spectra-Mass Spectrometry (SWATH-MS) on plasma samples from 23 patients with late-stage neovascular AMD following HAP-binding. Individuals were genotyped for the high risk CFH variant (T1277C) and binding to HAP was compared between wild type and risk variants. From a library of 242 HAP binding plasma proteins (1% false discovery rate), SWATH-MS revealed significant quantitative differences in the abundance of 32 HAP-binding proteins (p < 0.05) between the two homozygous groups. The concentrations of six proteins (FHR1, FHR3, APOC4, C4A, C4B and PZP) in the HAP eluted fractions and whole plasma were further analysed using ELISA and their presence in sections from human cadaver eyes was examined using immunofluorescence. All six proteins were found to be present in the RPE/choroid interface, and four of these (FHR1, FHR3, APOC4 and PZP) were associated with spherules in sub-RPE space. This study provides qualitative and quantitative information relating to the degree by which plasma proteins may contribute to sub-RPE deposit formation through binding to HAP spherules and how genetic differences might contribute to deposit formation. PMID- 29580722 TI - High-temperature Requirement Protein A1 Regulates Odontoblastic Differentiation of Dental Pulp Cells via the Transforming Growth Factor Beta 1/Smad Signaling Pathway. AB - INTRODUCTION: Dentinogenesis includes odontoblast differentiation and extracellular matrix maturation as well as dentin mineralization. It is regulated by numerous molecules. High-temperature requirement protein A1 (HtrA1) plays crucial roles in bone mineralization and development and is closely associated with the transforming growth factor beta (TGF-beta) signal in osteogenesis differentiation. Simultaneously, the TGF-beta1/small mother against decapentaplegic (Smad) signaling pathway is an important signaling pathway in various physiological processes and as a downstream regulation factor of HtrA1. However, the role of HtrA1 and its relationship with the TGF-beta1/Smad signaling pathway in dentin mineralization is unknown. METHODS: We detected the role of HtrA1 and its relationship with the TGF-beta1/Smad signaling pathway in odontoblastic differentiation of human dental pulp cells (hDPCs) in this study. First, hDPCs were cultured in mineralized medium, and odontoblastic differentiation was confirmed by investigating mineralized nodule formation, alkaline phosphatase (ALP) activity, and the expression of mineral-associated genes, including ALP, collagen I, and dentin sialophosphoprotein. Then, the expression of HtrA1 and TGF-beta1/Smad in hDPCs was investigated in hDPCs during mineralized induction. After HtrA1 knockdown by lentivirus, the mineralized nodule formation, ALP activity, and expression of mineral-associated genes and TGF-beta1/Smad genes were investigated to confirm the effect of HtrA1 on odontoblastic differentiation and its relationship with the TGF-beta1/Smad signaling pathway. RESULTS: The expression of HtrA1 and TGF-beta1 was increased during odontoblastic differentiation of hDPCs along with the messenger RNA expression of downstream factors of the TGF-beta1/Smad signaling pathway. In addition, lentivirus-mediated HtrA1 knockdown inhibited the process of mineralization and the expression of HtrA1 and TGF-beta1/Smad genes. CONCLUSIONS: These findings suggest that HtrA1 might positively regulate odontoblastic differentiation of hDPCs through activation of the TGF-beta1/Smad signaling pathway. PMID- 29580723 TI - The Performance of a Zirconium-based Root Filling Material with Artifact Reduction Properties in the Detection of Artificially Induced Root Fractures Using Cone-beam Computed Tomographic Imaging. AB - INTRODUCTION: Limited field of view cone-beam computed tomographic (CBCT) imaging has been used to augment clinical testing of vertical root fractures (VRFs); however, the presence of gutta-percha (GP) in the canal space generates substantial imaging artifacts that make fracture detection difficult. The purpose of this study was to evaluate the influence of a zirconium (Zr)-based root filling material with radiologic properties that reduce beam hardening (BH) artifacts using CBCT imaging in the in vitro diagnosis of VRFs. METHODS: One hundred seventy-six single-rooted mandibular premolar teeth were obtained, and half of these teeth were filled with GP or Zr (CPoint; EndoTechnologies, LLC, Shrewsbury, MA). VRFs were induced in 44 decoronated teeth in each group using an Instron (Norwood, MA) Universal Testing Machine. Each root was then placed in a dry human mandible and imaged with the Carestream 9000 3D CBCT system (Carestream Dental, Atlanta, GA). The images were evaluated by 6 oral maxillofacial radiologists (OMRs) and residents. RESULTS: The sensitivity was greater for detecting VRFs in the Zr group than the GP group (P = .035). However, the specificity was greater for the GP group than the Zr group (P = .028). Receiver operating characteristic area under the curve values were greater for the Zr group than the GP group, but these differences were not statistically significant. The OMRs outperformed the residents in the detection of VRFs in the Zr group with respect to specificity (P = .006) and positive predictive value (P = .012). CONCLUSIONS: The reduced BH of the Zr group improved the sensitivity of the detection of artificially induced VRFs. The ability to detect VRFs in the Zr group was further enhanced by clinical experience. PMID- 29580724 TI - Application of Enamel Matrix Derivative (Emdogain) in Endodontic Therapy: A Comprehensive Literature Review. AB - INTRODUCTION: Enamel matrix derivative (EMD) is a protein extract used for the treatment of periodontal defects and soft tissue recession. Its use in endodontics has been a subject of exploration, especially in regenerative procedures. The aim of this review was to evaluate the current literature available on the application of EMD in the field of endodontics. METHODS: An initial literature search of databases using different combinations of the search terms yielded 1089 articles. From the 29 qualified studies, there were 17 animal studies and 12 human case series and clinical trials. RESULTS: The evidence for the application of EMD as a direct pulp capping agent was relatively dichotomous. In determining the possible effect of EMD on pulpotomy procedures, only 1 animal study qualified under the criteria set forth previously. When comparing EMD against calcium hydroxide (Ca[OH]2), Portland cement, and mineral trioxide aggregate (MTA), Ca(OH)2 induced more histologic hard tissue formation, whereas MTA performed best clinically and radiographically. The scientific literature available is inconclusive on the effectiveness of EMD in preventing root resorption. In regeneration, EMD treatment induced mainly the formation of a cementumlike tissue at the apical region of the root's external surface and showed an ingrowth of newly formed hard tissues into the root canal space. CONCLUSIONS: The results of EMD application in endodontic treatments are highly variable, warranting additional research, specifically in the subjects of replantation and regeneration/revascularization.

AB - INTRODUCTION: Neurofibromatosis type 1 (NF1) or Von Recklinghausen disease is an autosomal dominant genetic disorder with multivisceral manifestations. We report the case of a spontaneous haemothorax in a young lady wearing this genetic pathology. CASE REPORT: A 31-year-old woman with kyphoscoliosis developed acute chest pain and dyspnea. The physical examination revealed a right pleuritic syndrome, coffee and milk spots and neurofibromas of the trunk. Biological assessment showed anemia at 6.4g/dl. Chest x-ray revealed a right side opacification. The pleural puncture showed an incoagulable hemorrhagic fluid. The chest CT scan showed no vascular abnormalities. The diagnosis of spontaneous haemothorax, revealing NF1, was retained. Transfusion and thoracic drainage were performed followed by haemostasis surgery. Pleural exploration showed pleural hematoma with regard to the 5th intercostal space. Electrocoagulation and declogging were performed. The evolution of the patient was favorable. CONCLUSION: Haemothorax is a rare and serious complication which may reveal NF1. It must be suspected when sudden and spontaneous white haemithorax occurs in NF1. PMID- 29580727 TI - Folate receptor-directed orthogonal click-functionalization of siRNA lipopolyplexes for tumor cell killing in vivo. AB - The delivery of small interfering RNA (siRNA) and its therapeutic usage as an anti-cancer agent requires a carrier system for selective internalization into the cytosol of tumor cells. We prepared folate-bearing formulations by first complexing siRNA with the novel azido-functionalized sequence-defined cationizable lipo-oligomer 1106 (containing two cholanic acids attached to an oligoaminoamide backbone in T-shape configuration) into spherical, ~100-200 nm sized lipopolyplexes, followed by surface-functionalization with various folate conjugated DBCO-PEG agents. Both the lipo-oligomer and the different defined shielding and targeting agents with mono- and bis-DBCO and varying PEG length were generated by solid phase supported synthesis. A bivalent DBCO surface agent with a PEG24 spacer was identified as the optimal formulation in terms of nanoparticle size, folate receptor (FR) targeting, cellular uptake and gene silencing in vitro. Notably, near-infrared fluorescence bioimaging studies showed that double-click incorporation of bivalent DBCO-PEG24 resulted in siRNA/1106/DBCO2-ss2-PEG24-FolA lipopolyplexes with extended biodistribution and intratumoral delivery in a subcutaneous FR-positive leukemia mouse model. Intravenous administration of analogous therapeutic siRNA lipopolyplexes (directed against the kinesin spindle motor protein EG5) mediated tumoral EG5 mRNA knockdown by ~60% and, in combination with the novel antitubulin drug pretubulysin, significantly prolonged survival of aggressive leukemia bearing mice without noticeable side effects. PMID- 29580728 TI - Effect of torrefaction pretreatment on the pyrolysis of rubber wood sawdust analyzed by Py-GC/MS. AB - The aim of this study was to investigate the effect of torrefaction on the pyrolysis of rubber wood sawdust (RWS) using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). Three typical torrefaction temperatures (200, 250, and 300 degrees C) and pyrolysis temperatures (450, 500, and 550 degrees C) were considered. The results suggested that only diethyl phthalate, belonging to esters, was detected at the torrefaction temperatures of 200 and 250 degrees C, revealing hemicellulose degradation. With the torrefaction temperature of 300 degrees C, esters, aldehydes, and phenols were detected, suggesting the predominant decomposition of hemicellulose and lignin. The double-shot pyrolysis indicated that the contents of oxy-compounds such as acids and aldehydes in pyrolysis bio-oil decreased with rising torrefaction temperature, implying that increasing torrefaction severity abated oxygen content in the bio-oil. With the torrefaction temperature of 300 degrees C, relatively more cellulose was retained in the biomass because the carbohydrate content in the pyrolysis bio-oil increased significantly. PMID- 29580729 TI - A review on microbial lipids as a potential biofuel. AB - Energy security, environmental concerns, and unstable oil prices have been the driving trifecta of demand for alternative fuels in the United States. The United States' dependence on energy resources, often from unstable oil-producing countries has created political insecurities and concerns. As we try to gain energy security, unconventional oil becomes more common, flooding the market, and causing the major downshift of the usual unstable oil prices. Meanwhile, consumption of fossil fuels and the consequent CO2 emissions have driven disruptions in the Earth's atmosphere and are recognized to be responsible for global climate change. While the significance of each of these three factors may fluctuate with global politics or new technologies, transportation energy will remain the prominent focus of multi-disciplined research. Bioenergy future depends on the price of oil. Current energy policy of the United States heavily favors petroleum industry. In this review, the current trend in microbial lipids as a potential biofuel is discussed. PMID- 29580730 TI - Risk factors for repeat surgical intervention in pediatric nephrolithiasis: A Pediatric Health Information System database study. AB - INTRODUCTION: Successful surgical therapy for pediatric upper urinary tract calculi (UUTC) minimizes the need for repeat surgical interventions. However, staged procedures, whether planned or unplanned, are sometimes necessary. We assessed predictors of repeat intervention for children with UUTC using a nationwide administrative dataset. METHODS: Using the Pediatric Health Information System (PHIS) dataset, we assessed children with UUTC undergoing shock wave lithotripsy (SWL) or ureteroscopy (URS) for an index stone from January 2010 to June 2015. Primary outcome was additional treatment for nephrolithiasis within 90 days. Patient and procedural variables were assessed as potential risks for retreatment. Multivariable logistic regression models were used to compare the risk of retreatment adjusting for potential confounding factors. RESULTS: A total of 2788 patients undergoing URS (2,216, 79.5%) and SWL (572, 20.5%) were identified. SWL, stenting at the index operation without pre index stenting, chronic comorbidities, renal calculi, and age <5 years were independent risk factors for retreatment. Use of ureteral stenting, most commonly employed in URS, was also a strong predictor of retreatment. Odds for reintervention, adjusted by multivariate modeling, are shown in the Figure. CONCLUSIONS: Adjusting for measured confounders, SWL is associated with a 2.6 fold higher risk of repeat stone-related interventions. Additional patient related factors also increase likelihood of retreatment. Intra-operative stent placement is a strong predictor of retreatment, perhaps serving as a marker for complex cases or planned staged procedures. Prospective studies are needed to assess comparative effectiveness of SWL and URS and improve mono-therapeutic success for children with UUTC. PMID- 29580731 TI - Active surveillance for antenatally detected ureteroceles: Predictors of success. AB - INTRODUCTION: Historically, ureteroceles were surgically treated, as patients were diagnosed after developing symptoms. However, with the advance of fetal medicine, antenatal detection has provided an opportunity to look at the natural history of ureteroceles. OBJECTIVES: With data derived from a retrospective chart review of patients with ureteroceles that were detected antenatally, the current study aimed to determine which group of children would be at risk for failure on active surveillance. It was hypothesized that single system ureteroceles (SSU) and male patients with duplex system ureteroceles (DSU) would be ideal for observation. METHODS: Outcomes were assessed by descriptive statistics. Kaplan Meier curves were utilized to estimate median duration on active surveillance in both single and duplex cohorts. Breakthrough febrile urinary tract infection (fUTI) and surgery were determined by Cox regression in the duplex system cohort. Surgery was considered surveillance failure. RESULTS: A total of 102 patients (64 females/38 males) met the criteria: 78 (76.5%) had DSU and 24 (23.5%) SSU. The overall median observation was 1.2 years (range 0.7-3.1). Follow-up ranged from 0.3 to 11.7 years for SSU, and from 0.02 to 17.3 years for DSU. The predictors of failure of active surveillance (AS) in DSU (surgical intervention) were male gender (HR 1.8, 1.0-3.3, P = 0.037), or fUTI (HR 3.1, 1.7-5.8, P = 0.002). Predictors of fUTI were contralateral hydroureter or ipsilateral hydronephrosis +/- hydroureter (OR 9.5, 1.2-71.7, P = 0.028). Interestingly, vesicoureteral reflux (VUR) was not a predictor of fUTI. The SSU patients were ideal for AS, while in DSU, surveillance was successful in 30% of patients who were primarily females without contralateral hydroureter or ipsilateral hydronephrosis +/- hydroureter. However, in contradiction to the hypothesis, males were at higher risk for surgical intervention in the DSU cohort. CONCLUSION: Active surveillance is an option for patients with antenatally detected ureteroceles, but careful long term follow up is mandatory. Parents should be advised that surgical intervention may still be necessary, particularly in males with DSU.

AB - INTRODUCTION: Studies have shown that non-stented distal hypospadias repair eliminates stent-related bladder spasm and stent removal discomfort without increasing complications; however, results are inconsistent. We performed a systematic review to assess the complication rates of non-stented compared to the stented distal hypospadias repair. METHODS: The literature search included randomized control trials (RCTs) and cohort studies published prior to October 2016 in all languages (PROSPERO CRD42016047563). All included studies were assessed according to Cochrane Collaborative recommendations and included for meta-analysis. Surgical outcomes from each treatment group were classified according to early complications and later final outcomes. Outcomes were expressed as relative risk (RR) and 95% confidence intervals (CI). Interstudy heterogeneity was assessed using chi-square and I2. Effect estimates were pooled using the inverse variant method with random effect model. Subgroup analysis was performed according to surgical technique (Mathieu versus tubularized incised plate) and study design. RESULTS: A total of 20 studies (14 cohorts, 6 RCTs) with 2466 hypospadias repairs (1290 non-stented, 1176 stented) were included for the meta-analysis. Serious risk of bias was noted among the cohort studies with publication bias likely present, while the included RCTs were of moderate methodological quality. The overall pooled effect estimates comparing non-stented versus stented distal hypospadias repair showed no between-group difference for outcomes of early and late complications (RR 0.83, 95% CI 0.46-1.50; RR 0.96, 95% CI 0.92, 1.48; respectively) CONCLUSIONS: Current evidence of low to moderate quality suggests that there is likely no outcome difference between non-stented and stented distal hypospadias repair. PMID- 29580733 TI - The administration of adjuvant chemo(-immuno) therapy in the post ACOSOG-Z0011 era; a population based study. AB - PURPOSE: The ACOSOG-Z0011-study has resulted in a trend to a more conservative treatment of the axilla for selected sentinel-node-positive patients. However, axillary nodal involvement has always been an important factor for tumor staging and tailoring adjuvant chemotherapy plans. This study evaluates the impact of omitting completion axillary lymph node dissection (cALND) on the administration of adjuvant chemo (-immuno)therapy in Dutch clinical T1-2N0M0 (cT1-2N0M0) sentinel-node-positive breast cancer patients. METHODS: Data were obtained from the nationwide NABON breast cancer audit. Descriptive analyses were used to demonstrate trends in axillary surgery and adjuvant chemo (-immuno)therapy. Multivariable logistic regression analyses were used to identify factors associated with the prescription of chemo (-immuno)therapy. RESULTS: In this cohort of 4331 patients, the omission of a cALND increased from 34% to 92%, and the administration of chemo (-immuno)therapy decreased from 68% to 55%, between 2011 and 2015 (P < 0.001). Patients treated with cALND had an OR of 2.2 for receiving adjuvant chemo (-immuno)therapy compared with SLNB only patients. Lower age, a hormone receptor (HR) status other than HR-positive, HER2-negative, increasing tumor grade and stage, and a lymph node status >= pN2 were independently associated with a higher probability of chemo (-immuno)therapy (P < 0.05). CONCLUSIONS: This study showed that Dutch cT1-2N0M0 sentinel node-positive breast cancer patients treated with cALND had a higher independent probability for receiving adjuvant chemo (-immuno)therapy compared with SLNB only patients, even when corrected for lymph node status and HR-status. Probably, the decisions to administer adjuvant chemo (-immuno)therapy were not only based on guidelines and tumor characteristics, but also on the preferences from physicians and patients. PMID- 29580734 TI - Morbidity of rectosigmoid resection in cytoreductive surgery for ovarian cancer. Risk factor analysis. AB - AIM: Rectosigmoid resection is often performed during cytoreductive surgery for ovarian cancer, to achieve the goal of no residual tumour. Here, we evaluated the morbidity associated with rectosigmoid resection and the underlying risk factors. METHODS: We retrospectively assessed consecutive patients managed with rectosigmoid resection during cytoreductive surgery for ovarian cancer at our centre in Paris, France, between 2005 and 2013. All previously identified risk factors were analysed. Major complications were defined as grade III-IV in the Clavien-Dindo classification. RESULTS: Of 228 patients, 116 had primary and 112 interval surgery; 43/228 [18.9%]; experienced major complications, and these were more common after primary surgery [24.1% vs. 13.4%, p = .04]. The 69 patients who had rectosigmoid resection [33 primary vs. 36 interval surgery, p = .32] had a higher morbidity rate compared to the other patients [30.4% vs. 14.6%, p = .006]. The anastomotic leakage rate was 2.89%. By multivariate logistic regression, independent risk factors for morbidity were postmenopausal status [adjusted odds ratio (aOR), 13.7; 95% confidence interval (95%CI), 1.2;161.9], surgery after neoadjuvant chemotherapy [aOR, 4.4; 95%CI, 1.1;18.8], and peritoneal stripping of the left; paracolic gutter [aOR, 11.3; 95%CI, 2.3;54.3]. CONCLUSION: The morbidity of rectosigmoid resection during cytoreductive surgery for ovarian cancer seems acceptable. Ileostomy does not seem associated with a lower risk of major complications or adjuvant bevacizumab with a higher complication rate. PMID- 29580735 TI - The impact of primary tumour location in patients undergoing hepatic resection for colorectal liver metastasis. AB - BACKGROUND: Primary tumour location has long been debated as a prognostic factor in colorectal cancer patients with liver metastases (CRLM) undergoing liver resection. This retrospective study was conducted to clarify the prognostic value of tumour location after radical hepatectomy for CRLM and its underlying causes. METHODS: We retrospectively analysed clinical data from 420 patients with CRLM whom underwent liver resection between January 2002 and December 2015. Right sided (RS) tumours include tumours located in the cecum, ascending colon, and transverse colon, and left-sided (LS) tumours include those located in the splenic flexure, descending colon, sigmoid colon, and rectum. RESULTS: Both overall survival (OS) and disease-free survival (DFS) were similar between patients with RS and LS primary tumours (5-year OS: 46.5% vs 38.3%, P = 0.699; 5 year DFS: 29.1% vs 22.4%, P = 0.536). Specifically, RAS mutation rate was significantly higher in patients with RS tumours (P = 0.007). Subgroup analysis showed that the RAS mutation on the LS and RS tumours have different prognostic impact for CRLM patients on long-term survival after hepatic resection (RS, OS: P = 0.437, DFS: P = 0.471; LS, OS: P < 0.001, DFS: P = 0.002). The multivariable analysis showed that RAS mutant is an independent factor influencing OS in patients with LS primary tumour only. CONCLUSIONS: The site of the primary tumour has no significant impact on the long-term survival in patients with CRLM undergoing radical surgery. However, prognostic value of RAS status differs depending on the site of the primary tumour. PMID- 29580736 TI - Quantitative phosphoproteomic analysis of caprine muscle with high and low meat quality. AB - During the conversion of muscle to meat, protein phosphorylation can regulate various biological processes that have important effects on meat quality. To investigate the phosphorylation pattern of protein on rigor mortis, goat longissimus thoracis and external intercostals were classified into two groups (high quality and low quality), and meat quality was evaluated according to meat quality attributes (Warner-Bratzler shear force, Color, pH and drip loss). A quantitative mass spectrometry-based phosphoproteomic study was conducted to analyze the caprine muscle at 12h postmortem applying the TiO2-SIMAC-HILIC (TiSH) phosphopeptide enrichment strategy. A total of 2125 phosphopeptides were identified from 750 phosphoproteins. Among them, 96 proteins had differed in phosphorylation levels. The majority of these proteins are involved in glucose metabolism and muscle contraction. The differential phosphorylation level of proteins (PFK, MYL2 and HSP27) in two groups may be the crucial factors of regulating muscle rigor mortis. This study provides a comprehensive view for the phosphorylation status of caprine muscle at rigor mortis, it also gives a better understanding of the regulation of protein phosphorylation on various biological processes that affect the final meat quality attributes. PMID- 29580737 TI - An approach for N-linked glycan identification from MS/MS spectra by target-decoy strategy. AB - Glycan structure determination serves as an essential step for the thorough investigation of the structure and function of protein. Currently, appropriate sample preparation followed by tandem mass spectrometry has emerged as the dominant technique for the characterization of glycans and glycopeptides. Although extensive efforts have been made to the development of computational approaches for the automated interpretation of glycopeptide spectra, the previously appeared methods lack a reasonable quality control strategy for the statistical validation of reported results. In this manuscript, we introduced a novel method that constructed a decoy glycan database based on the glycan structures in the target database, and searched the experimental spectra against both the target and decoy databases to find the best matched glycans. Specifically, a two-layer scoring scheme for calculating a normalized matching score is applied in the search procedure which enables the unbiased ranking of the matched glycans. Experimental analysis showed that our proposed method can report more structures with high confidence compared with previous approaches. PMID- 29580738 TI - SpliceVec: Distributed feature representations for splice junction prediction. AB - Identification of intron boundaries, called splice junctions, is an important part of delineating gene structure and functions. This also provides valuable insights into the role of alternative splicing in increasing functional diversity of genes. Identification of splice junctions through RNA-seq is by mapping short reads to the reference genome which is prone to errors due to random sequence matches. This encourages identification of splicing junctions through computational methods based on machine learning. Existing models are dependent on feature extraction and selection for capturing splicing signals lying in the vicinity of splice junctions. But such manually extracted features are not exhaustive. We introduce distributed feature representation, SpliceVec, to avoid explicit and biased feature extraction generally adopted for such tasks. SpliceVec is based on two widely used distributed representation models in natural language processing. Learned feature representation in form of SpliceVec is fed to multilayer perceptron for splice junction classification task. An intrinsic evaluation of SpliceVec indicates that it is able to group true and false sites distinctly. Our study on optimal context to be considered for feature extraction indicates inclusion of entire intronic sequence to be better than flanking upstream and downstream region around splice junctions. Further, SpliceVec is invariant to canonical and non-canonical splice junction detection. The proposed model is consistent in its performance even with reduced dataset and class-imbalanced dataset. SpliceVec is computationally efficient and can be trained with user-defined data as well. PMID- 29580739 TI - Clinical Implications of the BIM Deletion Polymorphism in Advanced Lung Adenocarcinoma Treated With Gefitinib. AB - BACKGROUND: Proapoptotic protein Bcl-2-like 11 (BIM) is a crucial tumor suppressor gene in lung cancer development. A 2903-bp genomic deletion polymorphism is present in BIM intron 2, which alters RNA splicing and impairs the generation of the death-inducing isoform of BIM and resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). In the present study, we investigated the clinical implications of this genetic polymorphism in patients with advanced lung adenocarcinoma treated with gefitinib. MATERIALS AND METHODS: After genotyping the BIM deletion polymorphism in 111 patients with stage IIIB or IV lung adenocarcinoma receiving gefitinib, the hazard ratio (HR) and 95% confidence interval (CI) for progression-free survival and overall survival were estimated using Cox proportional hazards models. RESULTS: Possession of >= 1 deletion allele of the BIM polymorphism was observed in 18.02% of the patients. The BIM deletion polymorphism was an independent indicator of a shorter PFS (7.5 months vs. 11.3 months; HR, 2.38; 95% CI, 1.30-4.34; P = .005) and shorter OS (9.9 months vs. 27.5 months; HR, 2.53; 95% CI, 1.37-4.65; P = .003). Additionally, patients carrying the BIM deletion allele were more likely to experience acquired gefitinib-resistant disease. CONCLUSION: Our results indicate that the BIM deletion polymorphism might be a promising germline biomarker for gefitinib treatment in Chinese patients with lung adenocarcinoma. PMID- 29580740 TI - Negative voice-content as a full mediator of a relation between childhood adversity and distress ensuing from hearing voices. AB - A key predictor of whether or not an individual who hears voices (auditory verbal hallucinations; AVH) meets criteria for a psychiatric diagnosis is the level of negative content of the voices (e.g., threats, criticism, abuse). Yet the factors that contribute to negative voice-content are still not well understood. This study aimed to test the hypotheses that levels of childhood adversity would predict levels of negative voice-content, and that negative voice-content would partially mediate a relation between childhood adversity and voice-related distress. These hypotheses were tested in a clinical sample of 61 patients with formally diagnosed psychotic disorders (48 schizophrenia, 13 bipolar). We found evidence consistent with negative voice-content fully (not partially) mediating the relation between childhood adversity and voice-related distress. Although bivariate analyses found depression to be associated with both negative voice content and voice-related distress, we found no evidence of an indirect effect of childhood adversity on either negative voice-content or voice-related distress via depression. Alternative study designs are now needed to test if our findings are replicable and causal. Should they be, it will be necessary for psychological therapies to devise ways to reduce negative voice-content itself, rather than just changing beliefs about voices. A number of techniques are discussed (Avatar Therapy, Compassion Focused Therapy, voice-dialogue) that already show promise for this. PMID- 29580741 TI - Accidental deaths among persons with schizophrenia: A nationwide population-based cohort study. AB - OBJECTIVES: Persons with schizophrenia have a shorter life expectancy by 15 20years compared to the background population, but little is known about deaths caused by accidents. We aimed to investigate the rates of accidental death among persons with schizophrenia and compare these rates with those of the background population. METHODS: We conducted a national register-based cohort study of all persons born in Denmark between 1955 and 2011. The cohort included 2,703,307 persons, representing 56,845,085 person years at risk. We compared rates of accidental death between persons with schizophrenia and those without by using Cox regression analysis. The main outcome measure was hazard ratio (HR) for accidental death. RESULTS: A total of 12,425 accidental deaths were identified, including 371 accidental deaths among persons with schizophrenia. We found an increased HR for both women with schizophrenia (10.47; 95% CI=8.07-13.58) and men with schizophrenia (8.33; 95% CI=7.44-9.33) compared to the background population. After adjusting for substance abuse, we found attenuated HRs for both women (HR=3.22; 95% CI=2.46-4.20) and men (HR=3.23; 95% CI=2.87-3.63). CONCLUSIONS: Schizophrenia is a strong independent risk factor for accidental deaths. Substance abuse seems to constitute a substantial part of the association. PMID- 29580742 TI - Propionibacterium Acnes Persists Despite Various Skin Preparation Techniques. AB - PURPOSE: To investigate the efficacy of various skin preparations at eradicating Propionibacterium acnes in the dermal layer of the skin. METHODS: Twelve healthy volunteers consented to participate in this study. Each subject's upper back was prepped using 4 different techniques: an isopropyl alcohol control, chlorhexidine gluconate paint, chlorhexidine gluconate plus a mechanical scrub, and a high concentration chlorhexidine gluconate plus a mechanical scrub. A 3-mm dermal punch biopsy specimen was obtained at each preparation site. The 4 punch biopsy specimens were cultured for 14 days to assess for P. acnes growth. A Fisher's exact test was used to compare the proportion of positive cultures in each group and across biopsy sites. A Skillings-Mack test was used to compare the degree of culture positivity between the treatment arms. RESULTS: There were no reported complications in any of our subjects. P. acnes grew in 7 of the 12 control sites, 5 of the 12 chlorhexidine gluconate sites, 6 of the 12 chlorhexidine plus mechanical scrub sites, and 6 of the 12 high-concentration chlorhexidine gluconate plus mechanical scrub sites. There were no statistically significant differences between any of the treatment arms (P = .820). CONCLUSIONS: P. acnes persisted despite a variety of clinically relevant skin antisepsis preparations and techniques. LEVEL OF EVIDENCE: Level II, prospective comparative study. PMID- 29580743 TI - Surgical Trends in Arthroscopic Hip Surgery Using a Large National Database. AB - PURPOSE: To assess the practice trends in hip arthroscopy, including femoroplasty, acetabuloplasty, and labral repair Current Procedure Terminology, 4th edition (CPT-4), codes that have been implemented since many of the previous studies were published, without concerns for Hawthorne or observer effect as can be seen during a board collection window, and in a larger volume of patients with a more comprehensive database than previous published data. METHODS: The MarketScan Commercial Claims and Encounters database was searched using CPT-4 codes to identify patients who underwent any arthroscopic hip procedure from 2008 to 2013. Patients identified were characterized by gender, age group, and year of the initial procedure. Regression analysis was used to evaluate differences in surgical trends between individual patient groups delineated by age and gender. The Cochran-Armitage trend test was used to identify significant differences in surgical trends seen yearly. RESULTS: A total of 62,782 arthroscopic hip procedures in 31,569 surgeries in 27,997 patients were identified and included from 2008 through 2013. The number of surgeries in the database increased every year. After changes to CPT coding in 2011, femoroplasty became the most common procedure in 2012, comprising 28% of all procedures performed in 2013. Patients ages 40 to 49 underwent the most procedures (7,467, 27%). Females were more likely to undergo any arthroscopic procedure during the study period (.068% vs .041%, P < .0001). A total of 2,754 patients (10%) underwent a second surgery during the study period. A total of 1,625 patients (6%) underwent a total hip arthroplasty following an arthroscopic procedure during the study period. CONCLUSIONS: Arthroscopic hip procedures continue to increase, with femoroplasty, labral repair, and acetabuloplasty being the 3 most common procedures performed. Females are more likely to undergo any procedure, and labral repair is now performed more commonly than labral debridement. LEVEL OF EVIDENCE: Level IV, cross-sectional study. PMID- 29580744 TI - Anthropometric Study of the Radiocapitellar Joint. AB - PURPOSE: There is scant knowledge about the relationship between the size of the radial head and the size of the capitellum. Also, no data exist comparing the size of the capitellum between the left and the right elbow. METHODS: Eight pairs of elbows and 12 single elbows from fresh-frozen cadavers were obtained for this study. The vertical height and anterior width of the capitellum were measured with digital calipers. Four different measurements were performed at the radial head: longest outer diameter, shortest outer diameter, the long dish diameter, and short dish diameter. The Pearson intrarater intraclass correlation coefficients were obtained for all measurements. RESULTS: For the paired elbows, the correlations ranged between 0.95 and 0.96 for the capitellar dimensions and 0.77 and 0.98 for the radial head dimensions. The correlations between the long outer diameter of the radial head with the vertical height and the anterior width of the capitellum were 0.8 and 0.9, respectively. CONCLUSIONS: There is a high correlation between the long outer diameter of the radial head and the vertical height of the capitellum as well its anterior width. There is also a high correlation between the left and the right elbow. CLINICAL RELEVANCE: These findings are relevant to radiocapitellar arthroplasty and may be useful for radiocapitellar prosthetic design as well as in the preoperative planning of cases in which the radial head and/or the capitellum is destroyed. PMID- 29580745 TI - Biomechanical characterization of three iliac screw fixation techniques: A finite element study. AB - We aim to characterize the biomechanical properties of a modified iliac screw fixation method compared with the classic iliac screw fixation and the S2 alar iliac screw (S2AI) fixation using a FEM. A three-dimensional, non-linear FEM of lumbosacral spine and pelvis (L1-pelvis) was modified to simulate 3 different iliac screw fixations based on posterior screw fusion. The peak von Mises stress (PVMS) values of the iliac screws in the 3 different iliac screw fixations were recorded in during flexion/extension/axial rotation/lateral bending. The interaction stress which arose between the screw head and the shaft of iliac screws, was also measured for each case. The PVMS values of the 3 different iliac screw fixation techniques were lower than the fatigue strength levels under physiological loadings. PVMS of iliac screws was observed in the screw shaft for S2AI, in the screw neck for the modified iliac screw technique, and in the offset connectors of the classic iliac screw technique. The interaction between the screw head and the neck was compressed in modified iliac screw fixation technique. On the other hand, distraction force was observed in the S2AI technique between the screw head and the screw shaft. This FEM study supports our previous clinical results, which found that the modified iliac screw fixation technique can be an effective alternative sacropelvic fixation technique comparable to the classic iliac screw and the S2AI technique. PMID- 29580746 TI - REVEAL risk score in patients with chronic thromboembolic pulmonary hypertension receiving riociguat. AB - BACKGROUND: The REVEAL risk score (RRS) was developed to predict survival in patients with pulmonary arterial hypertension (PAH), based on multiple patient characteristics. Herein we calculated RRS for patients in the randomized CHEST-1 study and open-label CHEST-2 extension study of riociguat in inoperable or persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH). We investigated the effect of riociguat vs placebo on RRS in the CHEST-1 study, and the relationship between RRS and long-term outcomes in the CHEST-2 study. METHODS: RRS was calculated post hoc for baseline and Week 16 of CHEST-1 and Week 12 of CHEST-2, based on 9 evaluable elements. Patients were grouped into risk strata by RRS. Relationships between RRS and both survival and clinical worsening free survival were examined by Kaplan-Meier and Cox proportional hazards analyses. RESULTS: Overall, 237 patients completed CHEST-1 and entered CHEST-2. In CHEST-1, riociguat significantly improved RRS (p < 0.0001) and risk stratum (p < 0.001) vs placebo from baseline to Week 16. RRS at baseline, and at Week 16, and change in RRS during CHEST-1 were significantly associated with survival (hazard ratios for a 1-point reduction in RRS: 0.702, 0.692, and 0.682, respectively) and clinical worsening-free survival (hazard ratios: 0.697, 0.719, and 0.754, respectively) over 2 years in CHEST-2. CONCLUSIONS: Riociguat improved RRS in patients with inoperable and persistent/recurrent CTEPH. RRS at baseline and Week 16, and change in RRS from baseline, predicted survival and clinical worsening-free survival. This analysis of RRS in patients with inoperable or persistent/recurrent CTEPH suggests utility for the RRS in indications beyond PAH.

AB - INTRODUCTION AND OBJECTIVES: Cardiac resynchronization therapy (CRT) is beneficial for selected heart failure (HF) patients, although nonresponse to therapy is still prevalent. We investigated a set of novel biomarkers associated with various pathophysiological pathways of HF. Our purpose was to assess their ability to predict clinical outcomes after CRT. METHODS: We studied 136 chronic HF patients undergoing CRT. We measured the plasma levels of fractalkine, pentraxin-3, hepatocyte growth factor (HGF), carbohydrate antigen-125, and matrix metalloproteinase-9 before and 6 months after CRT. The primary endpoint of the study was 5-year all-cause mortality, and we considered the absence of 6-month reverse remodelling (defined as at least a 15% decrease in end-systolic volume) as a secondary endpoint. RESULTS: Fifty-eight patients died during the 5-year follow-up period and 66 patients were categorized as nonresponders. In multivariable models, only an increased HGF was an independent predictor of both mortality (HR, 1.35; 95%CI, 1.11-1.64; P=.003; per 1 standard deviation increase) and the absence of reverse remodelling (OR, 1.83; 95%CI, 1.10-3.04; P=.01; per 1 standard deviation increase). Applying HGF to the basic multivariable model of both mortality (net reclassification improvement=0.69; 95%CI, 0.39-0.99; P<.0001; integrated discrimination improvement=0.06; 95%CI, 0.02-0.11) and reverse remodelling (net reclassification improvement=0.39; 95%CI, 0.07-0.71; P=.01; integrated discrimination improvement=0.03; 95%CI, 0.00-0.06) resulted in a statistically significant reclassification and discrimination improvement. CONCLUSIONS: Of the investigated biomarkers, only HGF predicted clinical outcomes following CRT independently of other parameters. Reclassification analyses showed that HGF measurements could be useful in refining patient selection. PMID- 29580751 TI - Novel 1,3,4-thiadiazoles inhibit colorectal cancer via blockade of IL-6/COX-2 mediated JAK2/STAT3 signals as evidenced through data-based mathematical modeling. AB - We attempted a preclinical study using DMH-induced CRC rat model to evaluate the antitumor potential of our recently synthesized 1,3,4-thiadiazoles. The molecular insights were confirmed through ELISA, qRT-PCR and western blot analyses. The CRC condition was produced in response to COX-2 and IL-6 induced activation of JAK2/STAT3 which, in turn, was due to the enhanced phosphorylation of JAK2 and STAT3. The treatment with 1,3,4-thiadiazole derivatives (VR24 and VR27) caused the significant blockade of this signaling pathway. The behavior of STAT3 populations in response to IL-6 and COX-2 stimulations was further confirmed through data-based mathematical modeling using the quantitative western blot data. Finally, VR24 and VR27 restored the perturbed metabolites associated to DMH induced CRC as evidenced through 1H NMR based serum metabolomics. The tumor protecting ability of VR24 and VR27 was found comparable or to some degree better than the marketed chemotherapeutics, 5-flurouracil. PMID- 29580750 TI - Targeted next-generation-sequencing for reliable detection of targetable rearrangements in lung adenocarcinoma-a single center retrospective study. AB - Oncogenic rearrangements leading to targetable gene fusions are well-established cancer driver events in lung adenocarcinoma. Accurate and reliable detection of these gene fusions is crucial to select the appropriate targeted therapy for each patient. We compared the targeted next-generation-sequencing Oncomine Focus Assay (OFA; Thermo Fisher Scientific) with conventional ALK FISH and anti-Alk immunohistochemistry in a cohort of 52 lung adenocarcinomas (10 ALK rearranged, 18 non-ALK rearranged, and 24 untested cases). We found a sensitivity and specificity of 100% for detection of ALK rearrangements using the OFA panel. In addition, targeted next generation sequencing allowed us to analyze a set of 23 driver genes in a single assay. Besides EML4-ALK (11/52 cases), we detected EZR ROS1 (1/52 cases), KIF5B-RET (1/52 cases) and MET-MET (4/52 cases) fusions. All EML4-ALK, EZR-ROS1 and KIF5B-RET fusions were confirmed by multiplexed targeted next generation sequencing assay (Oncomine Solid Tumor Fusion Transcript Kit, Thermo Fisher Scientific). All cases with EML4-ALK rearrangement were confirmed by Alk immunohistochemistry and all but one by ALK FISH. In our experience, targeted next-generation sequencing is a reliable and timesaving tool for multiplexed detection of targetable rearrangements. Therefore, targeted next generation sequencing represents an efficient alternative to time-consuming single target assays currently used in molecular pathology. PMID- 29580752 TI - Dose-dependent effects of frutalin on in vitro maturation and fertilization of pig oocytes. AB - The aim of the present study was to evaluate the effect of frutalin (FTL) on in vitro maturation (IVM), and fertilization (IVF) of pig oocytes. In the Experiment 1, cumulus-oocyte complexes (COCs) were submitted to IVM in maturation medium alone or supplemented with different FTL concentration (0.6, 6 and 60 MUg/mL), or 0.3 MUg/mL doxorubicin (DXR). After IVM, some oocytes were evaluated for chromatin configuration, and the remaining oocytes were submitted to in vitro fertilization. In Experiment 2, matured oocytes were fertilized in IVF medium alone (control) or in presence of different FTL concentration (0.6, 6 and 60 MUg/mL), or 0.3 MUg/mL DXR. After 18 h post fertilization, the endpoints penetration rate, monospermy, spermatozoa per oocyte, and the IVF efficiency were evaluated in both experiments. In Experiment 1, 6 and 60 MUg/mL FTL, as well as DXR increased (P < 0.05) the rate of oocytes with abnormal chromatin configuration when compared to oocyte matured in control medium alone or supplemented with 0.6 MUg/mL FTL. The percentage of meiotic resumption in oocytes cultured with 60 MUg/mL FTL or DXR was less (P < 0.05) than in the other treatments. Moreover, oocytes matured with 6 or 60 MUg/mL FTL and DXR had a lesser IVM efficiency when compared to those matured with 0.6 MUg/mL FTL or in control medium. Additionally, there was a greater (P < 0.05) with culture in a medium containing 6 MUg/mL FTL for the rate of partenogenetically activated oocytes when compared with the other treatments. Culturing of COCs during IVM in a medium containing 6 or 60 FTL resulted in a lesser (P < 0.05) sperm penetration and spermatozoa/oocyte rates when compared to other treatments, and IVF efficiency was less (P < 0.05) than that in control medium alone or with a medium containing 0.6 MUg/mL FTL. In Experiment 2, culturing in a medium containing 0.6 MUg/mL FTL resulted in greater (P < 0.05) monospermy and IVF efficiency rates when compared to culturing in the control medium. In addition, culturing in a medium with 6 and 60 MUg/mL FTL resulted in a lesser (P < 0.05) spermatozoa penetration, sperm/oocyte rates and IVF efficiency, although there were greater (P < 0.05) monospermy rates. In conclusion, culturing in a medium containing 0.6 MUg/mL FTL resulted in lesser spermatozoa penetration rates and number of spermatozoa/oocyte increasing the IVF efficiency without harmful effects. Use of a greater concentration of FTL in the medium has toxic effects during oocyte maturation and results in a reduced IVF efficiency.

The present study was conducted to evaluate the suitability of DGC (BoviPure(r), Percoll(r) and Accudenz(r)) and FC (Sephadex G-15(r)) sperm selection procedures for fresh-extended and cold-stored ram semen by assessment of post-treatment sperm quality variables. Twenty normospermic ejaculates from ten adult Merino rams were used. Sperm concentration of recovered cells was greater (P < 0.001) after BoviPure treatment than other procedures in both fresh and cold semen. With the Sephadex method, there were more desirable values than with use of DGC procedures in several sperm motility variables measured by using the CASA system. In non-refrigerated semen samples, the percentage of progressive sperm motility (%PSM) after Sephadex filtration was greater (P < 0.05) than after BoviPure treatment; the straightline velocity (VSL) value after Sephadex filtration was greater (P < 0.01) than after Accudenz treatment; the amplitude of lateral head displacement (ALH) after Sephadex and Accudenz treatment was less than non-filtered semen (P < 0.001) and after Percoll (P < 0.01) and BoviPure (P < 0.05) treatments. In cold-stored semen samples, the %PSM after Sephadex filtration was greater than non-filtered (P < 0.05) semen and after BoviPure (P < 0.05), Percoll (P < 0.05) and Accudenz (P < 0.001) treatments. It is concluded that Sephadex column filtration can be used to select ram sperm in non refrigerated and cooled semen, because percentage progressively motile sperm and some other sperm motility characteristics are greater with use of this techniques as compared with use of DGC methods. PMID- 29580754 TI - Energy utilization associated with regular activity breaks and continuous physical activity: A randomized crossover trial. AB - AIMS: To quantify and compare energy utilization associated with prolonged sitting alone, or interrupted with regular activity breaks and/or an additional bout of continuous physical activity. METHODS AND RESULTS: Thirty six adults (11 males, BMI 24.1 +/- 4.6) completed four interventions: (1) prolonged sitting (SIT), (2) sitting with 2-min of walking every 30 min (RAB), (3) prolonged sitting with 30-min of continuous walking at the end of the day (SIT + PA), (4) a combination of the activities in (2) and (3) above (RAB + PA). All walking was at a speed and incline corresponding to 60% VO2max. Energy utilization over 7 h for each intervention was estimated using indirect calorimetry. Compared to SIT, SIT + PA increased total energy utilization by 709 kJ (95% CI 485-933 kJ), RAB by 863 kJ (95% CI 638-1088 kJ), and RAB + PA by 1752 kJ (95% CI 1527-1927 kJ) (all p < 0.001). There was no difference in total energy utilization between SIT + PA and RAB, however, post-physical activity energy utilization in RAB was 632 kJ greater than SIT + PA (95% CI 561-704 kJ; p < 0.001). CONCLUSIONS: Short frequent activity, results in greater accumulation of elevated post-physical activity energy utilization compared to a single bout of continuous activity; however the total energy utilization is similar. Combining activity breaks with a longer continuous bout of activity will further enhance energy utilization, and in the longer term, may positively affect weight management of a greater magnitude than either activity pattern performed alone. TRIAL REGISTRATION: ANZCTR12614000624684. PMID- 29580755 TI - Incidence and clinical outcomes of the different neovascular forms of age-related macular degeneration in Valencia (Spain). AB - OBJECTIVE: To analyse the incidence and outcomes of the different neovascular subtypes in age-related macular degeneration (AMD). MATERIAL AND METHODS: A retrospective review was carried out on patients with neovascular AMD treated in the University and Polytechnic Hospital la Fe in Valencia by the same retinal physician (RGP) between December 2012 and July 2015. The anatomic classification of the neovascular lesions was recorded, as well as the number of intravitreal treatments administered and the change in visual acuity (VA) obtained throughout the follow-up. RESULTS: A total number of 174 eyes of 156 patients (mean age: 79.9years) with a minimum follow-up of 4 months were included. The anatomic classification of choroidal neovascularisation (CNV) showed the presence of type1 lesions in 40,8%, type2 lesions in 12%, type3 lesions in 31%, and mixed lesions in 14.4%, with 1.7% showing polypoidal choroidal vasculopathy features. Overall, the mean baseline VA was 0,32, improving to 0,38 at 24months, after having received a mean of 9.3 injections. Type2, 3, and mixed forms showed a visual result significantly lower than type1, but there was no significant difference in the polypoidal vasculopathy. CONCLUSIONS: Type 1 CNV was the most common finding, and was associated with a better visual prognosis, compared to the other neovascular lesions. PMID- 29580756 TI - Case series of ocular involvement due to dengue. First reported cases in Guatemala. AB - OBJECTIVE: Describe the ocular findings of a case series of 8 patients with a diagnosis of dengue. MATERIALS AND METHODS: Review of clinical records and interviews with patients during outpatient visits, after informed consent was obtained and following the ethical standards of the Helsinki declaration. The patients were diagnosed with diagnosis by IgM / IgG dengue serology in whom ocular involvement was identified, between January and October 2017 in Retinal vascular clinic of the "Dr. Rodolfo Robles Valverde Hospital", Guatemala. RESULTS: The 8 patients, 5 men and 3 women from rural areas in Guatemala, were diagnosed with dengue by IgM / IgG serology with associated ocular involvement. The mean age was 32.3 years, with the oldest being 45 years old and the youngest being 20 years old. The ocular manifestations identified were, 4 neuroretinitis, 3 venous obstructions, 3 maculopathies, 2 serous detachments, 1 episcleritis, and 1 vasculitis. Two patients developed optic atrophy after resolving the neuroretinitis, and 1 developed peri-foveal scarring after the maculopathy. The ocular involvement was resolved in all patients after treatment, with an improvement in visual acuity, although in some cases damage to the visual field developed as a sequela of neuroretinitis. CONCLUSION: It is necessary to consider dengue as an important differential diagnosis in an endemic country such as Guatemala. There are a large number of ocular manifestations due to direct involvement, as well as by an immune system reaction, and thus avoid considering the different ocular manifestations as idiopathic, or due to a different condition. PMID- 29580757 TI - External ophthalmomyiasis due to Dermatobia hominis. A case report. AB - CLINICAL CASE: A 46-year-old woman with no relevant medical history, native of Honduras and resident in Spain for one and a half months. The patient went to the Emergency Department due to inflammation of the upper eyelid of the right eye, with an area that simulated an abscess. This was drained (obtaining hardly any purulent content). Treatment was prescribed with oral and topical antibiotics, as well as an anti-inflammatory drug. One week later the patient returned, with improvement of the inflammatory signs, but with discomfort and corneal erosions. After eversion of the upper eyelid, a "worm" type parasite emerged from the tarsus. The extraction was completed with a clamp, and was later identified as Dermatobia hominis (Dh) by examination of a fresh specimen. The subsequent outcome of the patient was favourable. DISCUSSION: Preseptal cellulitis in patients from tropical and sub-tropical areas can be caused by Dh. PMID- 29580758 TI - Nitric oxide-donating compounds for IOP lowering in glaucoma. AB - INTRODUCTION: An elevated intraocular pressure (IOP) remains the main risk factor for progression of glaucoma upon which we can efficiently act. Pharmacological strategies to reduce IOP are directed towards the reduction of aqueous humour (AH) production and/or the increase in AH drainage through the uveoscleral pathway. However, there are no drugs currently available as first-line treatment to increase AH outflow primarily via the conventional route. Ocular nitric oxide (NO) production takes place in AH outflow pathways and in the ciliary muscle, modulating the cellular response to elevated IOP. METHODS: This review describes the mechanism of action of endogenous NO and NO-donating compounds that are under research. It includes information regarding pre-clinical and clinical studies previously conducted with these compounds, discussing their role and therapeutic potential in the pharmacological treatment of ocular hypertension in glaucoma. RESULTS: The topical ocular administration of NO-donating compounds significantly lowered IOP and maintained it in animal models of glaucoma and subjects with ocular hypertension. CONCLUSIONS: The mechanism of action of these compounds is novel and scientific evidence that shows promising results. However, there is a need for more comprehensive studies to assess long-term safety and tolerability in order to properly evaluate their use in chronic therapies. PMID- 29580759 TI - Uveitis and serous retinal detachment secondary to systemic dabrafenib and trametinib. AB - CASE REPORT: The case is presented of a 39-year-old woman with metastatic melanoma treated with dabrafenib and trametinib. She presented with a severe acute panuveitis with granulomatous anterior uveitis, vitritis, and multiple serous retinal detachments. Dabrafenib and trametinib were suspended, and treatment with a systemic and topical corticosteroid was started. A good response was obtained, with a recovery of visual acuity of 1.0 in both eyes within two weeks. DISCUSSION: Dabrafenib and trametinib can lead to severe uveitis. Treatment with corticosteroids and discontinuation of therapy with dabrafenib and trametinib led to an anatomical and functional improvement, and resolved the episode rapidly. Ophthalmologists must be aware of this toxicity, given the increasing use of those drugs. PMID- 29580760 TI - Iris metastasis as a first manifestation of lung adenocarcinoma. AB - OBJECTIVE: To describe a case of lung adenocarcinoma for which the first clinical manifestation was an iris metastasis. CASE REPORT: A 76-year-old male patient came for consultation referring a "pinkish speck" on his right eye. On biomicroscopy examination, a mass was found on the iris of the right eye. Subsequent systemic work-up of the patient revealed a left lung adenocarcinoma. DISCUSSION: Although uncommon, iris metastasis secondary to lung cancer should be part of differential diagnosis in iris tumours. PMID- 29580761 TI - The impact of social protection and poverty elimination on global tuberculosis incidence: a statistical modelling analysis of Sustainable Development Goal 1. AB - BACKGROUND: The End TB Strategy and the Sustainable Development Goals (SDGs) are intimately linked by their common targets and approaches. SDG 1 aims to end extreme poverty and expand social protection coverage by 2030. Achievement of SDG 1 is likely to affect the tuberculosis epidemic through a range of pathways. We estimate the reduction in global tuberculosis incidence that could be obtained by reaching SDG 1. METHODS: We developed a conceptual framework linking key indicators of SDG 1 progress to tuberculosis incidence via well described risk factor pathways and populated it with data from the SDG data repository and the WHO tuberculosis database for 192 countries. Correlations and mediation analyses informed the strength of the association between the SDG 1 subtargets and tuberculosis incidence, resulting in a simplified framework for modelling. The simplified framework linked key indicators for SDG 1 directly to tuberculosis incidence. We applied an exponential decay model based on linear associations between SDG 1 indicators and tuberculosis incidence to estimate tuberculosis incidence in 2035. FINDINGS: Ending extreme poverty resulted in a reduction in global incidence of tuberculosis of 33.4% (95% credible interval 15.5-44.5) by 2035 and expanding social protection coverage resulted in a reduction in incidence of 76.1% (45.2-89.9) by 2035; both pathways together resulted in a reduction in incidence of 84.3% (54.7-94.9). INTERPRETATION: Full achievement of SDG 1 could have a substantial effect on the global burden of tuberculosis. Cross sectoral approaches that promote poverty reduction and social protection expansion will be crucial complements to health interventions, accelerating progress towards the End TB targets.

AB - AIM: Major hepatic resection of a cirrhotic liver may result in a fatal clinical course. Preoperative erythropoietin (EPO) treatment has been shown to have protective properties and to stimulate liver regeneration. This study aims to investigate the effect of preoperative EPO on survival following major hepatic resection in a cirrhotic rat model. METHODS: Cirrhotic liver was induced by intraperitoneal injection of thioacetamide (200mg/kg/mL) in 72 Lewis rats. Each 36 rats received EPO (1IU/g, every second day, 5 times preoperatively) or saline (control) and major hepatectomy (removal of the left and half of the median lobe) was performed. Biochemical and immunohistochemical parameters, cytokines and overall survival were compared following surgery. RESULTS: Rats that received preoperative EPO had decreased hepatic aspartate aminotransferase, alanine aminotransferase and interleukin (IL)-1beta expression, 48hours following surgery. They had increased hepatocyte growth factor and vascular endothelial growth factor expression at 1hour, increased IL-6 expression at 24, 48 and 120hours and increased Ki-67, 120hours following surgery. Overall, survival was significantly improved among EPO-treated rats (P=0.034). CONCLUSION: Preoperative EPO treatment has a protective effect and stimulates liver regeneration, leading to improved overall survival following major hepatectomy in a cirrhotic rat model.

PMID- 29580767 TI - Fatty liver index is associated to pulse wave velocity in healthy subjects: Data from the Brisighella Heart Study. AB - BACKGROUND: Non-Alcoholic Fatty Liver Disease (NAFLD) is associated to increased risk of cardiovascular disease. Our aim was to evaluate association of indexes of fatty liver with arterial stiffness (AS). METHODS: We analyzed data of adult volunteers visited during the last Brisighella survey. We evaluated the Pulse Wave Velocity (PWV) and the following non-invasive indexes of liver steatosis: Fatty Liver Index (FLI), Lipid Accumulation Product (LAP), Hepatic Steatosis Index (HSI). We compared patients according to the risk of Non-Alcoholic Steatohepatitis (NASH): low-risk (BMI < 28 and no diabetes), intermediate-risk (BMI >= 28 or diabetes), high-risk (BMI >= 28 and diabetes). Multiple Linear Regression analysis was assessed for predictors of AS. RESULTS: We studied 1731 volunteers. In subjects with low metabolic risk, HSI (RR = 0.138, 95%CI 0.105 0.170, p < 0.001), FLI (RR = 0.024, 95%CI 0.016-0.032, p < 0.001), LAP (RR = 0.014, 95%CI 0.008-0.020, p < 0.001) and Serum Uric Acid (RR = 0.150, 95%CI 0.024 0.275, p = 0.019) were significant predictors of AS. HSI and FLI emerged as predictors of PWV in intermediate risk group (RR = 0.116, 95%CI 0.071-0.160, p < 0.001; RR = 0.010, 95%CI 0.001-0.020, p = 0.041). In volunteers with high risk, FLI and Uric Acid were related to PWV (RR = 0.049, 95%CI 0.011-0.087, p = 0.013; RR = 0.632, 95% CI 0.222-1.041, p = 0.003). CONCLUSION: Fatty liver indirect indexes were associated to AS in subjects with different metabolic risk profiles. PMID- 29580768 TI - Functional Connectivity Between Anterior Insula and Key Nodes of Frontoparietal Executive Control and Salience Networks Distinguish Bipolar Depression From Unipolar Depression and Healthy Control Subjects. AB - BACKGROUND: Patients with bipolar depression are characterized by dysregulation across the full spectrum of mood, differentiating them from patients with unipolar depression. The ability to switch neural resources among the default mode network, salience network, and executive control network (ECN) has been proposed as a key mechanism for adaptive mood regulation. The anterior insula is implicated in the modulation of functional network switching. Differential connectivity between anterior insula and functional networks may provide insights into pathophysiological differences between bipolar and unipolar mood disorders, with implications for diagnosis and treatment. METHODS: Resting-state functional magnetic resonance imaging data were collected from 98 subjects (35 unipolar, 24 bipolar, and 39 healthy control subjects). Pearson correlations were computed between bilateral insula seed regions and a priori defined target regions from the default mode network, salience network, and ECN. After r-to-z transformation, a one-way multivariate analysis of covariance was conducted to identify significant differences in connectivity between groups. Post hoc pairwise comparisons were conducted and Bonferroni corrections were applied. Receiver operating characteristics were computed to assess diagnostic sensitivity. RESULTS: Patients with bipolar depression evidenced significantly altered right anterior insula functional connectivity with the inferior parietal lobule of the ECN relative to patients with unipolar depression and control subjects. Right anterior insula-inferior parietal lobule connectivity significantly discriminated patients with bipolar depression. CONCLUSIONS: Impaired functional connectivity between the anterior insula and the inferior parietal lobule of the ECN distinguishes patients with bipolar depression from those with unipolar depression and healthy control subjects. This finding highlights a pathophysiological mechanism with potential as a therapeutic target and a clinical biomarker for bipolar disorder, exhibiting reasonable sensitivity and specificity. PMID- 29580769 TI - Novel DYW-type pentatricopeptide repeat (PPR) protein BLX controls mitochondrial RNA editing and splicing essential for early seed development of Arabidopsis. AB - In plants, RNA editing is a post-transcriptional process that changes specific cytidine to uridine in both mitochondria and plastids. Most pentatricopeptide repeat (PPR) proteins are involved in organelle RNA editing by recognizing specific RNA sequences. We here report the functional characterization of a PPR protein from the DYW subclass, Baili Xi (BLX), which contains five PPR motifs and a DYW domain. BLX is essential for early seed development, as plants lacking the BLX gene was embryo lethal and the endosperm failed to initiate cellularization. BLX was highly expressed in the embryo and endosperm, and the BLX protein was specifically localized in mitochondria, which is essential for BLX function. We found that BLX was required for the efficient editing of 36 editing sites in mitochondria. Moreover, BLX was involved in the splicing regulation of the fourth intron of nad1 and the first intron of nad2. The loss of BLX function impaired the mitochondrial function and increased the reactive oxygen species (ROS) level. Genetic complementation with truncated variants of BLX revealed that, in addition to the DYW domain, only the fifth PPR motif was essential for BLX function. The upstream sequences of the BLX-targeted editing sites are not conserved, suggesting that BLX serves as a novel and major mitochondrial editing factor (MEF) via a new non-RNA-interacting manner. This finding provides new insights into how a DYW-type PPR protein with fewer PPR motifs regulates RNA editing in plants. PMID- 29580770 TI - A new empiricism for harm reduction. AB - This commentary reflects on the key methodological innovations presented in Nicole Vitellone's recent book Social Science of the Syringe (Vitellone, 2017). Vitellone's book offers a critical account of harm reduction steeped in the material practices of empirical inquiry. In Vitellone's hands, harm reduction becomes a "matter of care"; a means of thinking, feeling and knowing the life worlds of people who inject drugs, such that these worlds may be encountered differently. Vitellone couches this analysis in terms of a novel social science of the syringe. Throughout her analysis, Vitellone asks us to reimagine the syringe, not as a fixed technical object, but as a dense point of capacities and affects around which certain forms of sociality become possible. The book follows the implications of this logic for scholars interested in the social and political contexts - the situated materialities - of injection drug use. I will close with some brief reflections on Vitellone's book in relation to broader efforts to advance a novel social science for harm reduction. PMID- 29580771 TI - Interactions of amyloid-beta peptides on lipid bilayer studied by single molecule imaging and tracking. AB - The amyloid-beta peptides (Abeta40 and Abeta42) feature prominently in the synaptic dysfunction and neuronal loss associated with Alzheimer's disease (AD). This has been proposed to be due either to interactions between Abeta and cell surface receptors affecting cell signaling, or to the formation of calcium permeable channels in the membrane that disrupt calcium homeostasis. In both mechanisms the cell membrane is the primary cellular structure with which Abeta interacts. Abeta concentrations in human bodily fluids are very low (pM-nM) rendering studies of the size, composition, cellular binding sites and mechanism of action of the oligomers formed in vivo very challenging. Most studies, therefore, have utilized Abeta oligomers prepared at micromolar peptide concentrations, where Abeta forms oligomeric species which possess easily observable cell toxicity. Such toxicity has not been observed when nM concentrations of peptide are used in the experiment highlighting the importance of employing physiologically relevant peptide concentrations for the results to be of biological significance. In this paper single-molecule microscopy was used to monitor Abeta oligomer formation and diffusion on a supported lipid bilayer at nanomolar peptide concentrations. Abeta monomers, the dominant species in solution, tightly associate with the membrane and are highly mobile whereas trimers and higher-order oligomers are largely immobile. Abeta dimers exist in a mixture of mobile and immobile states. Oligomer growth on the membrane is more rapid for Abeta40 than for the more amyloidogenic Abeta42 but is largely inhibited for a 1:1 Abeta40:Abeta42 mixture. The mechanism underlying these Abeta40-Abeta42 interactions may feature in Alzheimer's pathology. PMID- 29580773 TI - Patient-centeredness and endometriosis: Definition, measurement, and current status. AB - The patient-centeredness of care is important for health care quality, especially because it was recently associated with health-related quality of life, which is increasingly being recognized as the ultimate outcome parameter of health care. Therefore, insight into the definition, measurement, and current status of the patient-centeredness of clinics is important for all health care professionals caring for patients with endometriosis. The definition of patient-centered endometriosis care is based on research into the most common preferences, needs, and values of patients with endometriosis and can be summarized in ten dimensions. One valid and reliable questionnaire exists, the ENDOCARE questionnaire, which allows measuring the patient-centeredness status of an endometriosis clinic. This questionnaire has been used to benchmark centers in different countries and has allowed the identification of ten targets for improving the patient-centeredness of endometriosis care. The next step would be to use the ENDOCARE questionnaire before and after an improvement project.

PMID- 29580772 TI - Acute Brain Dysfunction: Development and Validation of a Daily Prediction Model. AB - BACKGROUND: The goal of this study was to develop and validate a dynamic risk model to predict daily changes in acute brain dysfunction (ie, delirium and coma), discharge, and mortality in ICU patients. METHODS: Using data from a multicenter prospective ICU cohort, a daily acute brain dysfunction-prediction model (ABD-pm) was developed by using multinomial logistic regression that estimated 15 transition probabilities (from one of three brain function states [normal, delirious, or comatose] to one of five possible outcomes [normal, delirious, comatose, ICU discharge, or died]) using baseline and daily risk factors. Model discrimination was assessed by using predictive characteristics such as negative predictive value (NPV). Calibration was assessed by plotting empirical vs model-estimated probabilities. Internal validation was performed by using a bootstrap procedure. RESULTS: Data were analyzed from 810 patients (6,711 daily transitions). The ABD-pm included individual risk factors: mental status, age, preexisting cognitive impairment, baseline and daily severity of illness, and daily administration of sedatives. The model yielded very high NPVs for "next day" delirium (NPV: 0.823), coma (NPV: 0.892), normal cognitive state (NPV: 0.875), ICU discharge (NPV: 0.905), and mortality (NPV: 0.981). The model demonstrated outstanding calibration when predicting the total number of patients expected to be in any given state across predicted risk. CONCLUSIONS: We developed and internally validated a dynamic risk model that predicts the daily risk for one of three cognitive states, ICU discharge, or mortality. The ABD-pm may be useful for predicting the proportion of patients for each outcome state across entire ICU populations to guide quality, safety, and care delivery activities.

PMID- 29580777 TI - Quality of Life After Cardiac Operations Based on the Minimal Clinically Important Difference Concept. AB - BACKGROUND: Health-related quality of life (HRQOL) is an increasingly important issue in assessing the consequences of any surgical or medical intervention. Our study aimed to evaluate change in HRQOL 6 months after elective cardiac operations and to identify specific predictors of poor HRQOL. METHODS: In this prospective, single-center study, HRQOL was evaluated before and 6 months after the operation using the Medical Outcome Study 36-Item Short Form Health Survey questionnaire and its two components: the Physical Component Summary and the Mental Component Summary. We distinguished patients with worsening of HRQOL according to the minimal clinically important difference. All consecutive adult patients undergoing cardiac operations were included. RESULTS: The preoperative and postoperative 36-Item Short Form Health Survey questionnaires were completed by 326 patients, and 24 patients died before completing follow-up questionnaires. On the basis of the definition used, clinically significant deterioration of HRQOL was observed in 93 patients (26.6%) for the Physical Component Summary and in 99 patients (28.2%) for the Mental Component Summary. Renal replacement for acute renal failure and mechanical ventilation for longer than 48 hours were independent risk factors for Physical Component Summary and Mental Component Summary worsening or death. CONCLUSIONS: Although our study showed overall improvement of quality of life after cardiac operations, more than one-quarter of the patients manifested deterioration of HRQOL at 6 months postoperatively. The findings from this study should help clinicians to inform patients about their likely postoperative functional status and quality of life. PMID- 29580778 TI - Two-Field Lymphadenectomy During Esophagectomy: The Presence of Thoracic Duct Lymph Nodes. AB - BACKGROUND: Resection of the thoracic duct is part of the formal en bloc mediastinal esophagolymphadenectomy for cancer, although with the adaptation of minimally invasive techniques, some centers started to leave the thoracic duct compartment in situ. However, previous studies reported thoracic duct lymph nodes in this compartment that may contain metastasis. The aim of this study was to assess the presence and number of lymph nodes in the fatty tissue surrounding the thoracic duct. METHODS: A right-sided thoracoscopic esophagectomy was performed on seven fresh-frozen human cadavers (male, n = 3; female, n = 4). The esophagus and lymph node stations 7, 8, and 9 were resected en bloc, followed by resection of the thoracic duct compartment consisting of the fatty tissue covering the aorta, the thoracic duct and thoracic duct lymph nodes. Lymph nodes were visualized by a hematoxylin and eosin stain and counted macroscopically and microscopically. RESULTS: Thoracic duct lymph nodes were found in 6 of 7 cadavers (86%), with a median number of 1 (range, 0 to 6). Nodes were predominantly located in the area of the azygos vein. A median of 4 subcarinal nodes (range, 1 to 8) and 2 periesophageal nodes (range, 1 to 4) were present. CONCLUSIONS: This study shows that thoracic duct lymph nodes are located within the fatty tissue surrounding the thoracic duct. Resection of this compartment during an esophagectomy for cancer increases lymph node yield. PMID- 29580779 TI - Long-Term Results for Clinical Stage IA Lung Cancer: Comparing Lobectomy and Sublobar Resection. AB - BACKGROUND: Lobectomy has been compared with sublobar resection for the treatment of stage IA non-small cell lung cancer (NSCLC). Accurate long-term data are lacking on the risk of recurrence in routine clinical practice. This study used a unique and representative dataset to compare recurrence, overall survival (OS), and lymph node staging between lobectomy and sublobar resection. METHODS: The American College of Surgeons performed a Special Study of the National Cancer Data Base, by reabstracting records to augment NSCLC data with enhanced information on preoperative comorbidity and cancer recurrence from 2007 to 2012. For patients treated with lobectomy or sublobar resection (wedge resection or segmentectomy) for clinical stage IA NSCLC, propensity matching and competing risks models compared 5-year OS and risk of cancer recurrence. Secondary measures included lymph nodes collected, pathologic upstaging, and surgical margin status. RESULTS: A total of 1,687 patients with stage IA NSCLC were identified (1,354 who underwent lobectomy, and 333 who had sublobar resections). Propensity matching yielded 325 pairs. Lobectomy and sublobar resection groups had similar 5-year OS (61.8% vs 55.6%, p = 0.561). The sublobar group had a 39% increased risk of NSCLC recurrence (hazard ratio, 1.39; 95% confidence interval, 1.04 to 1.87). Median lymph node counts were higher for lobectomy-treated patients (7 [3, 10] vs 1 [0, 4], p < 0.001)]. CONCLUSIONS: In an enhanced national dataset representative of outcomes for stage IA NSCLC, sublobar resection was associated with a 39% increased risk of cancer recurrence. The majority of patients treated with sublobar resection had an inadequate lymph node assessment. These real-world results must be considered when existing clinical trial results comparing these treatments are extrapolated for clinical use.

PMID- 29580781 TI - Elevated Urine Levels of Macrophage Migration Inhibitory Factor in Inflammatory Bladder Conditions: A Potential Biomarker for a Subgroup of Interstitial Cystitis/Bladder Pain Syndrome Patients. AB - OBJECTIVE: To investigate whether urinary levels of macrophage migration inhibitory factor (MIF) are elevated in interstitial cystitis/bladder pain syndrome (IC/BPS) patients with Hunner lesions and also whether urine MIF is elevated in other forms of inflammatory cystitis. METHODS: Urine samples were assayed for MIF by enzyme-linked immunosorbent assay. Urine samples from 3 female groups were examined: IC/BPS patients without (N = 55) and with Hunner lesions (N = 43), and non-IC/BPS patients (N = 100; control group; no history of IC/BPS; cancer or recent bacterial cystitis). Urine samples from 3 male groups were examined: patients with bacterial cystitis (N = 50), radiation cystitis (N = 18) and noncystitis patients (N = 119; control group; negative for bacterial cystitis). RESULTS: Urine MIF (mean MIF pg/mL +/- standard error of the mean) was increased in female IC/BPS patients with Hunner lesions (2159 +/- 435.3) compared with IC/BPS patients without Hunner lesions (460 +/- 114.5) or non IC/BPS patients (414 +/- 47.6). Receiver operating curve analyses showed that urine MIF levels discriminated between the 2 IC groups (area under the curve = 72%; confidence interval 61%-82%). Male patients with bacterial and radiation cystitis had elevated urine MIF levels (2839 +/- 757.1 and 4404 +/- 1548.1, respectively) compared with noncystitis patients (681 +/- 75.2). CONCLUSION: Urine MIF is elevated in IC/BPS patients with Hunner lesions and also in patients with other bladder inflammatory and painful conditions. MIF may also serve as a noninvasive biomarker to select IC/BPS patients more accurately for endoscopic evaluation and possible anti-inflammatory treatment. PMID- 29580782 TI - Physiological differences between female limited, alternative life history strategies: The Alba phenotype in the butterfly Colias croceus. AB - Across a wide range of taxa, individuals within populations exhibit alternative life history strategies (ALHS) where their phenotypes dramatically differ due to divergent investments in growth, reproduction and survivorship, with the resulting trade-offs directly impacting Darwinian fitness. Though the maintenance of ALHS within populations is fairly well understood, little is known regarding the physiological mechanisms that underlie ALHS and how environmental conditions can affect the evolution and expression of these phenotypes. One such ALHS, known as Alba, exists within females of many species in the butterfly genus Colias. Previous works in New World species not only found that female morphs differ in their wing color due to a reallocation of resources away from the synthesis of wing pigments to other areas of development, but also that temperature played an important role in these trade-offs. Here we build on previous work conducted in New World species by measuring life history traits and conducting lipidomics on individuals reared at hot and cold temperatures in the Old World species Colias croceus. Results suggest that the fitness of Alba and orange morphs likely varies with rearing temperature, where Alba females have higher fitness in cold conditions and orange in warm. Additionally shared traits between Old and New World species suggest the Alba mechanism is likely conserved across the genus. Finally, in the cold treatment we observe an intermediate yellow morph that may have decreased fitness due to slower larval development. This cost may manifest as disruptive selection in the field, thereby favoring the maintenance of the two discrete morphs. Taken together these results add insights into the evolution of, and the selection on, the Alba ALHS. PMID- 29580783 TI - Enhancement of fermentative hydrogen production from Spirogyra sp. by increased carbohydrate accumulation and selection of the biomass pretreatment under a biorefinery model. AB - In this work, hydrogen (H2) was produced through the fermentation of Spirogyra sp. biomass by Clostridium butyricum DSM 10702. Macronutrient stress was applied to increase the carbohydrate content in Spirogyra, and a 36% (w/w) accumulation of carbohydrates was reached by nitrogen depletion. The use of wet microalga as fermentable substrate was compared with physically and chemically treated biomass for increased carbohydrate solubilisation. The combination of drying, bead beating and mild acid hydrolysis produced a saccharification yield of 90.3% (w/w). The H2 production from Spirogyra hydrolysate was 3.9 L H2 L-1, equivalent to 146.3 mL H2 g-1 microalga dry weight. The presence of protein (23.2 +/- 0.3% w/w) and valuable pigments, such as astaxanthin (38.8% of the total pigment content), makes this microalga suitable to be used simultaneously in both food and feed applications. In a Spirogyra based biorefinery, the potential energy production and food-grade protein and pigments revenue per cubic meter of microalga culture per year was estimated on 7.4 MJ, US $412 and US $15, respectively, thereby contributing to the cost efficiency and sustainability of the whole bioconversion process.

AB - Bioelectrochemical system (BES) is a novel, self-sustaining metal removal technology functioning on the utilization of chemical energy of organic matter with the help of microorganisms. Experimental trials of two chambered BES reactor were conducted with varying substrate concentration using sodium acetate (500 mg/L to 2000 mg/L COD) and different initial chromium concentration (Cri) (10-100 mg/L) at different cathode pH (pH 1-7). In the current study mathematical models based on multiple linear regression (MLR) and non-linear regression (NLR) approach were developed using laboratory experimental data for determining chromium removal efficiency (CRE) in the cathode chamber of BES. Substrate concentration, rate of substrate consumption, Cri, pH, temperature and hydraulic retention time (HRT) were the operating process parameters of the reactor considered for development of the proposed models. MLR showed a better correlation coefficient (0.972) as compared to NLR (0.952). Validation of the models using t-test analysis revealed unbiasedness of both the models, with t critical value (2.04) greater than t-calculated values for MLR (-0.708) and NLR ( 0.86). The root-mean-square error (RMSE) for MLR and NLR were 5.06 % and 7.45 %, respectively. Comparison between both models suggested MLR to be best suited model for predicting the chromium removal behavior using the BES technology to specify a set of operating conditions for BES. Modelling the behavior of CRE will be helpful for scale up of BES technology at industrial level. PMID- 29580785 TI - Donor mesenchymal stem cell linetics after transamniotic stem cell therapy (TRASCET) for experimental spina bifida. AB - PURPOSE: We sought to examine donor mesenchymal stem cell (MSC) kinetics after transamniotic stem cell therapy (TRASCET) in experimental spina bifida. METHODS: Pregnant Sprague-Dawley dams exposed to retinoic acid for the induction of fetal neural tube defects received volume-matched intra-amniotic injections on gestational day 17 (E17; term=E22): either amniotic fluid MSCs (afMSCs) labeled with a luciferase reporter gene (n=78), or luciferase protein alone (n=66). Samples from twelve organ systems from each surviving fetus with spina bifida (total n=60) were screened via microplate luminometry at term. RESULTS: Donor afMSCs were identified exclusively in the placenta, umbilical cord, spleen, bone marrow, hip bones, defect, and brain. Luminometry was negative in control fetuses receiving luciferase alone (p<0.001). Signal intensity in relative light units (RLUs) was moderately correlated between the defect and the hip bones (rho=0.38, p=0.048), and between the placenta and the brain (rho=0.40, p=0.038). CONCLUSIONS: Amniotic mesenchymal stem cells engraft to specific sites after concentrated intra-amniotic injection in the setting of spina bifida. A hematogenous route encompassing the bone marrow as well as distant central nervous system homing are fundamental constituents of cell trafficking. These findings must be considered during eventual patient selection for transamniotic stem cell therapy in the prenatal management of spina bifida. PMID- 29580786 TI - Neurodevelopmental outcomes in CDH survivors: A single institution's experience. AB - PURPOSE: Survivors of congenital diaphragmatic hernia (CDH) face high morbidity. We studied the neurodevelopmental outcomes of CDH survivors at a single institution. METHODS: CDH survivors born July 2006-March 2016 at a free-standing children's hospital were reviewed. Neurodevelopment was assessed using the Peabody Developmental Motor Scales (PDMS-2) broken into gross, fine, and total motor quotients. Data collected included prenatal variables (liver herniation, defect laterality, observed:expected total fetal lung volume (o:eTFLV) on MRI), birth demographics (sex, race, estimated gestational age (EGA), birth weight (BtWt), 5 min APGAR, associated anomalies), and therapies/hospital course (HFOV/HFJV, ECMO, timing of repair, pulmonary hypertension (PHTN) severity, length of stay, ventilator days). Variables were analyzed using mixed linear modeling. RESULTS: Sixty-eight children were included. Most patients had left sided CDH (55/68, 81%) without liver herniation (42/68, 62%). ECMO utilization was 25/68 (37%). The mean [95% confidence interval] gross motor quotient for the entire cohort was 87 [84-91], fine motor quotient was 92 [88-96], and total motor quotient was 88 [84-93], representing below average, average, and below average functioning, respectively. o:eTFLV predicted fine motor quotient among prenatal variables. Associated anomalies and ECMO use predicted all quotients in the final model. CONCLUSIONS: Associated anomalies and ECMO use predict neurodevelopmental delay in CDH survivors.

PMID- 29580787 TI - Using bibliometrics to analyze the state of academic productivity in US pediatric surgery training programs. AB - BACKGROUND: The Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements state that faculty must establish and maintain an environment of inquiry and scholarship. Bibliometrics, the statistical analysis of written publications, assesses scientific productivity and impact. The goal of this study was to understand the state of scholarship at Pediatric Surgery training programs. METHODS: Following IRB approval, Scopus was used to generate bibliometric profiles for US Pediatric Surgery training programs and faculty. Statistical analyses were performed. RESULTS: Information was obtained for 430 surgeons (105 female) from 48 US training programs. The mean lifetime h index/surgeon for programs was 14.4 +/- 4.7 (6 programs above 1 SD, 9 programs below 1 SD). The mean 5-yearh-index/surgeon for programs was 3.92 +/- 1.5 (7 programs above 1 SD, 8 programs below 1 SD). Programs accredited after 2000 had a lower lifetime h-index than those accredited before 2000 (p=0.0378). Female surgeons had a lower lifetime h-index (p<0.0001), 5-yearh-index (p=0.0049), and m quotient (p<0.0001) compared to males. Mean lifetime h-index increased with academic rank (p<0.0001), with no gender differences beyond the assistant professor rank (p=NS). CONCLUSION: Variability was identified based on institution, gender, and rank. This information can be used for benchmarking the academic productivity of faculty and programs and as an adjunct in promotion/tenure decisions. TYPE OF STUDY: Original Research.

AB - RATIONALE AND OBJECTIVES: To use an automatic computed tomography (CT) dose monitoring system to analyze the institutional chest and abdominopelvic CT dose data as regards the updated 2017 American College of Radiology (ACR) diagnostic reference levels (DRLs) based on water-equivalent diameter (Dw) and size-specific dose estimates (SSDE) to detect patient-size subgroups in which CT dose can be optimized. MATERIALS AND METHODS: All chest CT examinations performed between July 2016 and April 2017 with and without contrast material, CT of the pulmonary arteries, and abdominopelvic CT with and without contrast material were included in this retrospective study. Dw and SSDE were automatically calculated for all scans using a previously validated in-house developed Matlab software and stored into our CT dose monitoring system. CT dose data were analyzed as regards the updated ACR DRLs (size groups: 21-25 cm, 25-29 cm, 29-33 cm, 33-37 cm, 37-41 cm). SSDE and volumetric computed tomography dose index (CTDIvol) were used as CT dose parameter. RESULTS: Overall, 30,002 CT examinations were performed in the study period, 3860 of which were included in the analysis (mean age 62.1 +/- 16.4 years, Dw 29.0 +/- 3.3 cm; n = 577 chest CT without contrast material, n = 628 chest CT with contrast material, n = 346 CT of chest pulmonary, n = 563 abdominopelvic CT without contrast material, n = 1746 abdominopelvic CT with contrast material). Mean SSDE and CTDIvol relative to the updated DRLs were 43.3 +/- 26.4 and 45.1 +/- 27.9% for noncontrast chest CT, 52.3 +/- 23.1 and 52.0 +/- 23.1% for contrast-enhanced chest CT, 68.8 +/- 29.5 and 70.0 +/- 31.0% for CT of pulmonary arteries, 41.9 +/- 29.2 and 43.3 +/- 31.3% for noncontrast abdominopelvic CT, and 56.8 +/- 22.2 and 58.8 +/- 24.4% for contrast-enhanced abdominopelvic CT. Lowest dose compared to the DRLs was found for the Dw group of 21-25 cm in noncontrast abdominopelvic CT (SSDE 30.4 +/- 21.8%, CTDIvol 30.8 +/- 21.4%). Solely the group of patients with a Dw of 37-41 cm undergoing noncontrast abdominopelvic CT exceeded the ACR DRL (SSDE 100.3 +/- 59.0%, CTDIvol 107.1 +/- 63.5%). CONCLUSIONS: On average, mean SSDE and CTDIvol of our institutional chest and abdominopelvic CT protocols were lower than the updated 2017 ACR DRLs. Size specific subgroup analysis revealed a wide variability of SSDE and CTDIvol across CT protocols and patient size groups with a transgression of DRLs in noncontrast abdominopelvic CT of large patients (Dw 37-41 cm). PMID- 29580789 TI - Designing a Curriculum for Professionalism and Ethics Within Radiology: Identifying Challenges and Expectations. AB - Although professionalism and ethics represent required competencies, they are more challenging than other competencies to design a curriculum for and teach. Reasons include variability in agreed definitions of professionalism within medicine and radiology. This competency is also framed differently whether as roles, duties, actions, skills, behavior, beliefs, and attitudes. Standardizing a curriculum in professionalism is difficult because each learner's (medical student/resident) professional experiences and interactions will be unique. Professionalism is intertwined throughout all (sub) specialties and areas and its teaching cannot occur in isolation as a standalone curriculum. In the past, professionalism was not emphasized enough or at all, with global (or no) assessments, with the potential effect of trainees not valuing it. Although we can teach it formally in the classroom and informally in small groups, much of professionalism is witnessed and learned as "hidden curricula". The formal, informal, and hidden curricula often contradict each other creating confusion, disillusion, and cynicism in trainees. The corporatization of medicine pressurizes us to increase efficiency (throughput) with less focus on aspects of professionalism that add value, creating a disjoint between what we do in practice and preach to trainees. Progressively, expectations for our curriculum include providing evidence for the impacts of our efforts on patient outcomes. Generational differences in the perception of professionalism and the increasingly diverse and multicultural society in which we live affects our interpretation of professionalism, which can add to confusion and misunderstanding. The objectives of this article are to outline challenges facing curriculum design in professionalism and to make suggestions to help educators avoid or overcome them. PMID- 29580790 TI - Recognition of Neonatal Lymphatic Flow Disorder: Fetal MR Findings and Postnatal MR Lymphangiogram Correlation. AB - RATIONALE AND OBJECTIVES: This study aimed to describe prenatal and postnatal imaging features and outcomes of neonates with neonatal lymphatic disorders (NLDs). MATERIALS AND METHODS: An institutional review board-approved search of the radiology database for patients with NLD identified five patients. Inclusion criteria include prenatal imaging (fetal magnetic resonance [MR] imaging and ultrasound) and postnatal three-dimensional T2 Sampling Perfection with Application optimized Contrasts using different flip angle Evolution (SPACE) and dynamic contrast-enhanced MR lymphangiography within 6 months of life. Chart review was undertaken to evaluate morbidity and mortality. RESULTS: Prenatal finding of "nutmeg lung" or fetal pulmonary lymphatic disorder was identified in all five patients on fetal MR imaging, and in four of five patients on fetal ultrasound. Postnatal dynamic contrast-enhanced MR lymphangiography demonstrated abnormal lymphatic flow to the lungs in four of five patients, but absent in the single patient with coexisting hypoplastic left heart syndrome (HLHS). Dermal backflow was seen in one patient, also the only patient with prenatal body wall edema. Three patients with lymphatic flow to the lungs only were classified as neonatal chylothorax. The patient with dermal backflow and perfusion to the lungs was diagnosed with central lymphatic flow disorder (CLFD). The HLHS patient with normal lymphatic perfusion maintained the HLHS diagnosis. Of the five patients, the patient with CLFD and the one with HLHS expired because of respiratory distress. CONCLUSIONS: NLDs can be recognized on prenatal and postnatal imaging and may be primary, as in neonatal chylothorax or CLFD, or secondary. In this small series, "nutmeg lung" was present in all patients. Prenatal imaging demonstrates that body wall edema may correlate with postnatal dermal backflow, which, in our small cohort, carried a poor prognosis. PMID- 29580791 TI - Breast Lesions Detected via Molecular Breast Imaging: Physiological Parameters Affecting Interpretation. AB - RATIONALE AND OBJECTIVES: To evaluate correlations between molecular breast imaging (MBI) descriptor characteristics and positive predictive value (PPV) in detecting breast cancer. MATERIALS AND METHODS: A retrospective review was performed on 193 suspicious findings from 153 women (31-81 years) with positive MBI examinations. We assessed associations between (i) lesion pattern (mass vs. nonmass) and PPV; (ii) lesion pattern and suspected likelihood of cancer (low vs. moderate vs. high); (iii) background parenchymal uptake (BPU) (homogeneous vs. heterogeneous) and PPV; (iv) breast density (dense vs. non-dense) and PPV; and (v) BPU and density. RESULTS: One hundred ten of 153 patients were diagnosed with malignancy or high-risk pathology (PPV1 = 71.9%), and 130/193 biopsies resulted in malignant or high-risk lesions (PPV3 = 67.4%). Biopsies of mass vs. nonmass findings had comparable PPV3 (71.7% vs. 61.3%; P = .0717). Mass findings were correlated with higher suspicion for cancer than nonmass findings (P < .001). There was no significant difference in PPV3 when comparing biopsies from homogeneous vs. heterogeneous BPU (72.5% vs. 60.7%; P = .103). No association was found between patients' BPU and diagnosed cancer or high-risk lesions (P = .513). Biopsies from nondense breasts demonstrated higher PPV3 than biopsies from dense breasts (85.4% vs. 60.6%; P = .0025); patients with nondense breasts were more likely to be diagnosed with cancer or high-risk pathology (PPV1 = 87.8% vs. 66.0%; P = .00844). Dense breasts had a greater association with heterogeneous BPU (P = .0844). CONCLUSION: Neither variability in mass or nonmass positive MBI findings, nor variability in BPU on MBI were significant determinants for the probability of malignancy. Dense breasts were associated with lower predictability and heterogeneous BPU on MBI. PMID- 29580792 TI - Observer Variability in Breast Cancer Diagnosis between Countries with and without Breast Screening. AB - RATIONAL AND OBJECTIVES: Image reporting is a vital component of patient management depending on individual radiologists' performance. Our objective was to explore mammographic diagnostic efficacy in a country where breast cancer screening does not exist. MATERIALS AND METHODS: Two mammographic test sets were used: a typical screening (TS) and high-difficulty (HD) test set. Nonscreening (NS) radiologists (n = 11) read both test sets, while 52 and 49 screening radiologists read the TS and HD test sets, respectively. The screening radiologists were classified into two groups: a less experienced (LE) group with <=5 years' experience and a more experienced (ME) group with >=5 years' experience. A Kruskal-Wallis and Tukey-Kramer post hoc test were used to compare reading performance among reader groups, and the Wilcoxon matched pairs tests was used to compare TS and ND test sets for the NS radiologists. RESULTS: Across the three reader groups, there were significant differences in case sensitivity (chi2 [2] = 9.4, P = .008), specificity (chi2 [2] = 10.3, P = .006), location sensitivity (chi2 [2] = 19.8, P < .001), receiver operating characteristics, area under the curve (chi2 [2] = 19.7, P < .001) and jack-knife free-response receiver operating characteristics (JAFROCs) (chi2 [2] = 18.1, P < .001). NS performance for all measured scores was significantly lower than those for the ME readers (P < .006), while only location sensitivity was lower (chi2 [2] = 17.5, P = .026) for the NS compared to the LE group. No other significant differences were observed. CONCLUSION: Large variations in mammographic performance exist between radiologists from screening and nonscreening countries.

AB - Patient-specific biomechanical modelling can improve preoperative surgical planning. This requires patient-specific geometry as well as patient-specific material properties as input. The latter are, however, still quite challenging to estimate in vivo. This study focuses on the estimation of the mechanical properties of the arterial wall. Firstly, in vivo pressure, diameter and thickness of the arterial wall were acquired for sheep common carotid arteries. Next, the animals were sacrificed and the tissue was stored for mechanical testing. Planar biaxial tests were performed to obtain experimental stress stretch curves. Finally, parameters for the hyperelastic Mooney-Rivlin and Gasser Ogden-Holzapfel (GOH) material model were estimated based on the in vivo obtained pressure-diameter data as well as on the ex situ experimental stress-stretch curves. Both material models were able to capture the in vivo behaviour of the tissue. However, in the ex situ case only the GOH model provided satisfactory results. When comparing different fitting approaches, in vivo vs. ex situ, each of them showed its own advantages and disadvantages. The in vivo approach estimates the properties of the tissue in its physiological state while the ex situ approach allows to apply different loadings to properly capture the anisotropy of the tissue. Both of them could be further enhanced by improving the estimation of the stress-free state, i.e. by adding residual circumferential stresses in vivo and by accounting for the flattening effect of the tested samples ex vivo. * Competing interests: none declared * Word count: 4716.

AB - OBJECTIVE: Acute kidney injury (AKI) occurs frequently after cardiac surgery. Levosimendan might reduce the incidence of AKI in patients undergoing cardiac surgery. The authors investigated whether levosimendan administration could reduce AKI incidence in a high-risk cardiac surgical population. DESIGN: Post hoc analysis of a multicenter randomized trial. SETTING: Cardiac surgery operating rooms and intensive care units of 14 centers in 3 countries. PARTICIPANTS: The study comprised 90 patients who underwent mitral valve surgery with an estimated glomerular filtration rate <60 mL/min/1.73 m2 and perioperative myocardial dysfunction. INTERVENTIONS: Patients were assigned randomly to receive levosimendan (0.025-0.2 MUg/kg/min) or placebo in addition to standard inotropic treatment. MEASUREMENTS AND MAIN RESULTS: Forty-six patients were assigned to receive levosimendan and 44 to receive placebo. Postoperative AKI occurred in 14 (30%) patients in the levosimendan group versus 23 (52%) in the placebo group (absolute difference -21.8; 95% confidence interval -41.7 to -1.97; p = 0.035). The incidence of major complications also was lower (18 [39%]) in the levosimendan group versus that in the placebo group (29 [66%]) (absolute difference -26.8 [-46.7 to -6.90]; p = 0.011). A trend toward lower serum creatinine at intensive care unit discharge was observed in the levosimendan group (1.18 [0.99-1.49] mg/dL) versus that in the placebo group (1.39 [1.05-1.76] mg/dL) (95% confidence interval -0.23 [-0.49 to 0.01]; p = 0.07). CONCLUSIONS: Levosimendan may improve renal outcome in cardiac surgery patients with chronic kidney disease undergoing mitral valve surgery who develop perioperative myocardial dysfunction. Results of this exploratory analysis should be investigated in future properly designed randomized controlled trials. PMID- 29580797 TI - Frailty in Cardiac Surgery. PMID- 29580798 TI - The South Asian Origins of the Global Network to Eradicate Blindness: WHO, NGOs, and Decentralization. AB - The global network to eradicate blindness emerged out of the work of Western and South Asian professionals to eradicate smallpox which was endemic in South Asia. The history of the emergence of the global network to eradicate blindness demonstrates a shift from vertical command and control public health programs directed by the WHO, to the decentralized public health services originating in non-profit, non-governmental organizations and coordinated by the WHO. The WHO constitution started with a federal regionalist structure that encouraged collaboration and coordination with NGOs. In South Asia in particular, epidemiologists and general medical practitioners moved from eradicating smallpox through the WHO to creating their own domestic and international NGOs based in various countries with a mission to control blindness in South Asia and Africa. In 1975, pushed by the WHO Director General, these new NGOs in turn joined with individual ophthalmologists and existing blind member associations to form the International Agency for the Prevention of Blindness. Thus, the WHO was shaped by, and shaping, international NGOs such as the IAPB. The IAPB pushed for the formation of the WHO Prevention of Blindness program. This was the earliest example of how the IAPB facilitates bottom-up agenda-setting in the WHO. In 1980, when the WHO officially closed the smallpox program, the Prevention of Blindness program first received independent funding. Presently, the IAPB acts as a decentralized arm of the WHO. PMID- 29580799 TI - Gold nanoparticles dispersion stability under dynamic coating conditions in capillary zone electrophoresis. AB - Capillary zone electrophoresis (CZE) of unmodified gold nanoparticles (Au NPs) was investigated in terms of dispersion stability in a presence of buffering counter-ions in background electrolyte (BGE). Capillary length, migration time and electric field strength were identified among factors influencing particles CZE. Moreover, BGE electrolysis was found to significantly affect analyses repeatability. The adsorption of NPs to capillary wall was recognized as the main problem. It was shown that this inconvenience can be overcome by the application of relatively big counter-ions. According to this observation, steric stabilization of NPs suspension by BGE components during CZE was hypothesized. In result, repeatable CZE of bare Au NPs under dynamic coating conditions was shown. PMID- 29580800 TI - Construction of chiral ligand exchange capillary electrochromatography for d,l amino acids enantioseparation and its application in glutaminase kinetics study. AB - A chiral ligand exchange capillary electrochromatography (CLE-CEC) protocol was designed and implemented for d,l-amino acids enantioseparation with poly(maleic anhydride-styrene-methacryloyl-l-arginine methyl ester) as the coating. The block copolymer was synthesized through the reversible addition fragmentation chain transfer reaction. In the constructed CLE-CEC system, poly (methacryloyl-l arginine methyl ester) moiety of the block copolymer played the role as the immobilized chiral ligand and Zn (II) was used as the central ion. Key factors, including pH of buffer solution, ratio of Zn (II) to ligands, the mass ratio of monomers in the block copolymer, which affect the enantioresolution were investigated. Comparing with the bare capillary, the CLE-CEC enantioresolution was enhanced greatly with the coating one. 5 Pairs of d,l-amino acids enantiomers obtained baseline separation with 5 pairs partly separated. The mechanism of enhancement enantioresolution of the developed CLE-CEC system was explored briefly. Further, good linearities were achieved in the range of 25.0 MUM-5.0 mM for quantitative analysis of d-glutamine (r2 = 0.997) and l-glutamine (r2 = 0.991). Moreover, the proposed CLE-CEC assay was successfully applied in the kinetics study of glutaminase by using l-glutamine as the substrate. PMID- 29580801 TI - Reversible Concanavalin A (Con A) ligands immobilization on metal chelated macroporous cellulose monolith and its selective adsorption for glycoproteins. AB - The present work deals with the development of novel affinity monolith with reversible protein ligands for protein chromatography. As for the formation of reversible ligands, Concanavalin A (Con A) is chelated with Cu(II)-iminodiacetic acid (IDA) immobilized macroporous cellulose monolith (MCM) for glycoprotein adsorption. The reversible immobilization is realized by Cu ions, which bridge affinity ligands and support by strong chelation interaction. The fabrication process of reversible Con A immobilized adsorbent is studied, especially with regards to the effect of synthesis conditions on the ligands immobilization. The adsorption behavior is then evaluated to elucidate the potential of Con A-Cu(II) IDA-MCM for protein chromatography. It reveals that the static adsorption capacity and dissociation constant of glucose oxidase (GOD) on Con A-Cu(II)-IDA MCM are determined to be 17.4 +/- 0.6 mg mL-1 and 0.055 +/- 0.011 mg mL-1 by Langmuir model. With frontal analysis, the dynamic binding capacity of GOD at 10% breakthrough point is about 11.4 +/- 1.0 mg mL-1 and changes less with an increase of flow velocity from 0.2 to 1.0 mL min-1. Moreover, Con A-Cu(II)-IDA MCM displays weak nonspecific adsorption for the impurities and is able to successfully enrich glycoprotein ovalbumin (OVA) from diluted chicken egg white. In addition, Con A-Cu(II)-IDA-MCM exhibits excellent stability by the repeated adsorption/desorption operations. By taking these advantages of high adsorption capacity, excellent specificity and structure stability, the prepared affinity adsorbent of Con A-Cu(II)-IDA-MCM has great potential for high performance protein chromatography. PMID- 29580802 TI - Poly(butylene terephthalate) based novel achiral stationary phase investigated under supercritical fluid chromatography conditions. AB - Poly(butylene terephthalate) based novel stationary phase (SP), composed of planar aromatic phenyl group together with ester group monomer units, was designed for supercritical fluid chromatography (SFC) use. As expected from its structure, this phase shows planarity recognition of isomeric aromatics and closely similar compounds. Interestingly, for most analytes, the retention behavior of this SP is significantly distinct from that of the 2-ethylpyridine based SPs which is among the most well-known SFC dedicated phases. Although the poly(butylene terephthalate) is coated on silica gel, the performance of the column did not change by using extended range modifiers such as THF, dichloromethane or ethyl acetate and column robustness was confirmed by cycle durability testing. PMID- 29580803 TI - Childbirth Narratives of Women With Posttraumatic Stress Symptoms in the Postpartum Period. AB - OBJECTIVE: To examine cognitive, emotional, and perceptual differences in the childbirth narratives of women with high levels of posttraumatic stress symptoms (PTSS) compared with women with low levels of PTSS in the postpartum period. DESIGN: A cross-sectional design. Participants were retrospectively assigned to the high or low PTSS group on the basis of their scores on the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) administered at 1 week and 3 months after childbirth. SETTING: Participants' homes and Internet survey. PARTICIPANTS: Twenty-five women were included in the high PTSS group (PPQ score >= 12), and 25 were included in the low PTSS group (PPQ score <= 1). METHODS: Participants completed the PPQ and a writing task about the birth experience 1 week after birth and completed an online version of the PPQ 3 months after birth. Characteristics of the narratives were analyzed and compared between the two groups using the Linguistic Inquiry Word Count. RESULTS: Compared with participants with low levels of PTSS, participants with high levels of PTSS reported more negative emotions, including horrific images connected to labor and birth and fewer positive emotions. Participants with high levels of PTSS used more sensory and perceptual terms (tactile, visual, and auditory). In contrast, women with low levels of PTSS described more active participation during birth and used more future tense verbs. CONCLUSION: Our findings suggest the aspects that are involved in the development and maintenance of PTSS after birth and may be considered for use in clinical practice to improve quality of care and women's health during the postpartum period. PMID- 29580804 TI - Neurometabolite levels in antipsychotic-naive/free patients with schizophrenia: A systematic review and meta-analysis of 1H-MRS studies. AB - BACKGROUND: Studies using proton magnetic resonance spectroscopy (1H-MRS) have reported altered neurometabolite levels in patients with schizophrenia. However, results are possibly confounded by the influence of antipsychotic (AP). Thus, this meta-analysis aimed to examine neurometabolite levels in AP-naive/free patients with schizophrenia. METHODS: A literature search was conducted using Embase, Medline, and PsycINFO to identify studies that compared neurometabolite levels in AP-naive/free patients with schizophrenia to healthy controls (HCs). Eight neurometabolites (glutamate, glutamine, glutamate + glutamine, N acetylaspartate [NAA], choline, creatine, myo-inositol, and gamma-Aminobutyric acid [GABA]) and seven regions of interest (ROI; medial prefrontal cortex, dorsolateral prefrontal cortex, frontal white matter, occipital lobe, basal ganglia, hippocampus/medial temporal lobe, and thalamus) were examined. RESULTS: Twenty-one studies (N = 1281) were included in the analysis. The results showed lower thalamic NAA levels (3 studies, n = 174, effect size = -0.56, P = 0.0005) in the patient group. No group differences were identified for other neurometabolites. CONCLUSIONS: Our findings suggest that impaired neuronal integrity in the thalamus may be a potential trait maker in the early stages of schizophrenia.

AB - Succinate is known to act as an inflammatory signal in classically activated macrophages through stabilization of HIF-1alpha leading to IL-1beta production. Relevant to this, hypoxia is known to drive succinate accumulation and release into the extracellular milieu. The metabolic alterations associated with succinate release during inflammation and under hypoxia are poorly understood. Data are presented showing that Mycoplasma arginini infection of VM-M3 cancer cells enhances the Warburg effect associated with succinate production in mitochondria and eventual release into the extracellular milieu. We investigated how succinate production and release was related to the changes of other soluble metabolites, including itaconate and 2-HG. Furthermore, we found that hypoxia alone could induce succinate release from the VM-M3 cells and that this could occur in the absence of glucose-driven lactate production. Our results elucidate metabolic pathways responsible for succinate accumulation and release in cancer cells, thus identifying potential targets involved in both inflammation and hypoxia.

PMID- 29580807 TI - Immunogenicity and antitumor activity of the superlytic lambdaF7 phage nanoparticles displaying a HER2/neu-derived peptide AE37 in a tumor model of BALB/c mice. AB - Phage display technique has been increasingly researched for vaccine design and delivery strategies in recent years. In this study, the AE37 (Ii-Key/HER-2/neu 776-790) peptide derived from HER2 (human epidermal growth factor receptor protein) was used as a fused peptide to the lambda phage (lambdaF7) coat protein gpD, and the phage nanoparticles were used to induce antitumor immunogenicity in a TUBO model of breast cancer in mice. Mice were immunized with the AE37 peptide displaying phage, lambdaF7 (gpD::AE37) every 2-week intervals over 6-weeks, then the generated immune responses were evaluated. An induction of CTL immune response by the lambdaF7 (gpD::AE37) construct compared to the control lambdaF7 and buffer groups was observed in vitro. Moreover, in the in vivo studies, the vaccine candidate showed promising prophylactic and therapeutic effects against the HER2 overexpressing cancer in BALB/c mice. PMID- 29580806 TI - Targeting the NRF-2/RHOA/ROCK signaling pathway with a novel aziridonin, YD0514, to suppress breast cancer progression and lung metastasis. AB - Metastasis is a major cause of breast cancer-associated mortality. Natural products extracted from herbs provide rich bioactive compounds with anticancer efficacy but may have limited or moderate potency and considerable toxicity. We developed a novel aziridonin, YD0514, by aziridinating oridonin, a natural product of the medicinal herb Rabdosia rubescens. In this study, we found that YD0514 significantly inhibited proliferation, motility, and adhesion of metastatic breast cancer cell lines MDA-MB-231, GI101, GILM2, and GILM3. YD0514 also decreased the protein expression of matrix metalloproteinases 2 and 9 (MMP2 and MMP9), focal adhesion kinase (FAK), and integrin family members. Importantly, YD0514 suppressed the growth of metastatic breast cancer xenograft tumors and significantly inhibited lung metastasis in vivo. Lastly, we showed that YD0514's anti-metastatic effect on highly aggressive breast cancer is mediated via regulating the NRF-2/RHOA/ROCK signaling pathway. These results demonstrate that YD0514, the first active analog based on an oridonin D-ring modification, has the potential to be developed as an anti-metastasis therapy for patients with metastatic cancers. PMID- 29580808 TI - Basement membrane destruction by pancreatic stellate cells leads to local invasion in pancreatic ductal adenocarcinoma. AB - Stroma invasion is an important step in pancreatic cancer progression. However, how pancreatic ductal adenocarcinoma (PDAC) with ductal structure invades the surrounding stroma has not been clear. Here, we elucidated the mechanism of stromal invasion of PDAC, using organoids. From resected PDAC specimens, we established human PDAC organoids, which developed ductal and basement membrane (BM) structures. When the organoids were co-cultured with pancreatic stellate cells (PSCs) in a collagen matrix, organoids lost their BM and ductal structures, and invaded collagen matrix more frequently than did mono-cultured organoids. Interestingly, direct contact by PSCs to PDAC organoids was observed before BM destruction. Matrix metalloproteinase (MMP) 2 or membrane type-1 MMP (MT1MMP) knockdown in PSCs significantly attenuated BM destruction by PSCs, and retained the ductal structures in organoids. Our results imply that direct contact by PSCs induces BM destruction and stromal invasion of PDAC via MMP2 which binds to MT1MMP on PSCs. PMID- 29580809 TI - Commentary regarding Gannon et al. "Viral infections and breast cancer - A current perspective". PMID- 29580810 TI - Accurate detection and quantification of epigenetic and genetic second hits in BRCA1 and BRCA2-associated hereditary breast and ovarian cancer reveals multiple co-acting second hits. AB - BACKGROUND: This study characterizes the second hit spectrum in BRCA1 and BRCA2 associated breast and ovarian cancers at both gene loci to investigate if second hit mechanisms are mutually exclusive or able to coincide within the same tumor. METHODS: Loss of heterozygosity, somatic point mutations and copy number alterations along with promoter methylation were studied in 56 breast and 15 ovarian cancers from BRCA1 and BRCA2 germline mutation carriers. A mathematical methodology was introduced to quantify the tumor cell population carrying a second hit. RESULTS: Copy neutral LOH was the most prevalent LOH mechanism in this cohort (BC 69%, OC 67%). However, only 36% of BC and 47% of OC showed LOH in all cancerous cells. Somatic intragenic deletions and methylated subclones were also found in combination with (partial) loss of heterozygosity. Unequivocal deleterious somatic point mutations were not identified in this cohort. CONCLUSION: Different mechanisms inactivating the wild type allele are present within the same tumor sample at various extents. Results indicate that BRCA1/2 linked breast and ovarian cancer cells are predominantly characterized by LOH, but harbor a complex combination of second hits at various frequencies. PMID- 29580811 TI - Characterizing alleles with large deletions using region specific extraction. AB - Two novel HLA class II alleles, DRB4*03:01N and DQB1*03:276N, containing large deletions were identified during routine typing. Extraction of DNA encompassing the deletions was carried out with a panel of capture oligonucleotides followed by whole genome amplification. Next generation DNA sequencing was then used to characterize the sequences. DRB4*03:01N has a 16 kilobase pair deletion stretching upstream from intron 2 toward centromeric DRB8. DQB1*03:276N has two deletions separated by 844 nucleotides. The first deletion (3.7 kilobase pairs) is upstream of intron 1 and the second deletion removes 3.3 kilobase pairs further upstream towards centromeric DQA2. PMID- 29580812 TI - DDX3 in HIV-1 infection and sensing: A paradox. AB - HIV-1 sensors and their signaling features have been an ongoing topic of intense research over the last decade, as these mechanisms fail to establish protective immunity against HIV-1. Here, we discuss how HIV-1 infects dendritic cells (DCs) and which sensors play a role in recognizing viral DNA and RNA in these specialized immune cells. We will elaborate on the RNA helicase DDX3, which is crucial in translation initiation of HIV-1 mRNA, but also fulfills an important role as RNA sensor and inducer of antiviral immunity in DCs. As DDX3 is indispensable for HIV-1 replication, the virus cannot escape sensing by DDX3, which is an important aspect of its function. Last but not least, we will discuss how HIV-1 suppresses DDX3 sensing and how this impacts the viral load in HIV-1 infected individuals. PMID- 29580813 TI - Association between impaired IL-10 production following exposure to Staphylococcus aureus enterotoxin B and disease severity in eosinophilic chronic rhinosinusitis. AB - BACKGROUND: IL-10 is a major anti-inflammatory cytokine that prevents inflammation-mediated tissue damage. We characterized the production of IL-10 by sinonasal tissue cells following exposure to Staphylococcus aureus enterotoxin B (SEB), which elicits cellular responses and is associated with the pathogenesis of eosinophilic chronic rhinosinusitis (ECRS). METHODS: Dispersed nasal polyp (NP) cells and uncinate tissue (UT) cells were prepared from patients with CRS with and without NP, respectively. Cells were incubated with SEB, and then the levels of IL-10 in the cell supernatants were determined. The effect of neutralizing IL-10 on SEB-induced IL-5, IL-13, IFN-gamma, and IL-17A production was examined. Expression of IL-10 in NPs was also determined. RESULTS: IL-10 was expressed in infiltrating inflammatory cells in NPs. NP cells, especially non adherent NP cells, produced substantial amounts of IL-10 in response to SEB. Although baseline production of IL-10 was significantly higher in NP cells than UT cells, the degree of IL-10 response to SEB was not significantly different between the cell types. The degree of IL-10 production was negatively correlated with the degree of eosinophilia both in tissues and peripheral blood whereas positively correlated with the 1-s forced expiratory volume/forced vital capacity ratio. Patients with severe ECRS displayed a significant decrease in IL-10 production compared with those with non-ECRS. IL-10 neutralization significantly augmented SEB-induced IL-13 and IFN-gamma production by NP cells. CONCLUSIONS: Impaired IL-10 production in response to SEB in NP may exacerbate the pathophysiology of ECRS including eosinophilia and lower airway obstruction. PMID- 29580814 TI - Development and Evaluation of a New Formative Assessment of Surgical Performance. AB - BACKGROUND: Formative assessment of operative performance is a mandatory part of surgical training. Engagement with assessment is limited in part by the time consuming nature and the high perceived stakes of current assessment tools. OBJECTIVES: Our aims were to develop and collect validity evidence for a new operative assessment tool that addresses barriers to assessment that current trainers and trainees experience. METHODS: We developed the Generic Operative Supervised Learning Event (GOSLE). Orthopedic trainees were invited to complete GOSLEs with their trainers after surgical procedures. Experienced consultants assessed videotaped operations performed by trainees using the GOSLE. Validity evidence for content, relationships to other scores, internal structure, response process, and consequences of testing were evaluated. RESULTS: A total of 250 GOSLEs were completed. A strong correlation was found between the GOSLE scores and the Procedure-Based Assessment ratings (r = 0.87, p < 0.001). Rasch analysis confirmed satisfactory internal structure of the rating scale, with sequential increases in rating as performance improved. The reproducibility coefficient was 0.88, with 10 assessments of the same trainee who has to achieve a reliability coefficient of 0.8. Over 90% of users found the GOSLE easy to use, with most preferring it to other assessment methods. Feedback quality was higher using the GOSLE than with current assessments. CONCLUSION: We have collected validity evidence across multiple domains in support of the GOSLE. Its psychometric performance is comparable to that of current assessments. It is preferred by trainers and trainees over existing assessments. It stimulates high-quality, actionable feedback which better supports formative assessment. By addressing issues experienced with existing assessments, we expect engagement among users to be high. PMID- 29580815 TI - Age dependent variations in the deep brain photoreceptors (DBPs), GnRH-GnIH system and testicular steroidogenesis in Japanese quail, Coturnix coturnix japonica. AB - The complex physiology of aging involves a number of molecular and biochemical events, manifested as signs of senescence. Japanese quail is a very unique and advantageous model to study the signs and symptoms of senescence in the central and peripheral modules of HPG axis. In the present study, we have investigated the age dependent variations in hypothalamic deep brain photoreceptors (DBPs), central GnRH-I/II-GnIH-Mel1cR system, testicular GnRH-GnIH system, testicular steroidogenic genes and proteins, androgen receptor (AR) and serum testosterone level in quail of different age groups [3-wk (sexually immature), 6-wk (sexually mature and crossed the puberty), 16-wk (adult, sexually active and showing full breeding phase) and 144-wk (aged)]. Findings of our present study showed the differential expression of these genes/proteins in quail of different age groups. The low levels of the DBPs, GnRH-I, GnIH, Mel1cR in hypothalamus and GnRH-II in midbrain, significantly decreased testicular GnRH/GnRH-R-GnIH, steroidogenic genes/proteins and serum testosterone were observed in immature quail. The significantly increased expression of opsins in the DBPs, GnRH-I, GnIH, Mel1cR in hypothalamus and GnRH-II in midbrain influences the testicular GnRH-GnIH and stimulate the testicular steroidogenesis in mature and adult quail. In aged quail, the significantly decreased levels of hypothalamic DBPs, GnRH-I, GnIH, Mel1cR and midbrain GnRH-II modulates the testicular GnRH-GnIH and further suppresses the genes/proteins involved in steroidogenesis and results in reduced serum testosterone. Hence, it can be concluded from our findings that the testicular steroidogenesis and its neuroendocrine regulation varies with age, in Japanese quail. PMID- 29580816 TI - Overexpression of Egr2 and Egr4 protects rat brains against ischemic stroke by downregulating JNK signaling pathway. AB - OBJECTIVE: The purpose of this study was to investigate the effect of Egr2 and Egr4 upregulation on ischemic stroke recovery of rats. METHODS: In this study, Sprague Dawley (SD) rats assigned at random into control, sham and MCAO (middle cerebral artery occlusion) group were treated accordingly to build MCAO models. The neurological severity scores (NSS) test was applied to assess rats' behavior. Triphenyltetrazolium chloride (TTC) staining reflected infarct areas while Nissl staining revealed the number of neurons. Levels of pro-inflammatory cytokines (interleukin [IL]-1beta, IL-6 and tumor necrosis factor [TNF]-alpha) were judged by enzyme-linked immunosorbent assay (ELISA) in brain and serum tissues. We applied western blot to check the expression of Egr2, Egr4 and JNK/c-JUN (c-Jun N terminal kinase) pathway. Further grouping of rats were based on various transfection, requiring control, sham, MCAO, MCAO + Egr2 cDNA (complementary DNA), MCAO + Egr4 cDNA, MCAO + Egr2 cDNA + Egr4 cDNA group to observe difference in MCAO recovery and JNK/c-JUN-pathway-related protein expression. RESULTS: Under successful modeling of MCAO, western blot results suggested down-regulation of Egr2 and Egr4 and overexpression of pro-inflammatory cytokines. The JNK/c-JUN pathway was activated. On upregulation of Egr2 and Egr4 in infarct areas, neurological function of SD rats recovered along with repressed JNK/c-JUN pathway activation and increased neuron number. CONCLUSION: Upregulation of Egr2 and Egr4 could demote the activation of JNK/c-JUN pathway and the expression of pro inflammatory cytokines in MCAO rats, so that Egr2 and Egr4 might be potential targets for ischemic stroke in future. PMID- 29580817 TI - Concrete action now: UN High-Level Meeting on Tuberculosis. PMID- 29580818 TI - Tuberculosis: advances and challenges in development of new diagnostics and biomarkers. AB - Tuberculosis remains the leading cause of death from an infectious disease worldwide. Early and accurate diagnosis and detection of drug-sensitive and drug resistant tuberculosis is essential for achieving global tuberculosis control. Despite the introduction of the Xpert MTB/RIF assay as the first-line rapid tuberculosis diagnostic test, the gap between global estimates of incidence and new case notifications is 4.1 million people. More accurate, rapid, and cost effective screening tests are needed to improve case detection. Diagnosis of extrapulmonary tuberculosis and tuberculosis in children, people living with HIV, and pregnant women remains particularly problematic. The diagnostic molecular technology landscape has continued to expand, including the development of tests for resistance to several antituberculosis drugs. Biomarkers are urgently needed to indicate progression from latent infection to clinical disease, to predict risk of reactivation after cure, and to provide accurate endpoints for drug and vaccine trials. Sophisticated bioinformatic computational tools and systems biology approaches are being applied to the discovery and validation of biomarkers, with substantial progress taking place. New data have been generated from the study of T-cell responses and T-cell function, serological studies, flow cytometric-based assays, and protein and gene expression studies. Alternative diagnostic strategies under investigation as potential screening and triaging tools include non-sputum-based detection with breath-based tests and automated digital radiography. We review developments and key achievements in the search for new tuberculosis diagnostics and biomarkers. We highlight gaps and challenges in evaluation and rollout of new diagnostics and biomarkers, and prioritise areas needing further investment, including impact assessment and cost-benefit studies. PMID- 29580819 TI - Tuberculosis: progress and advances in development of new drugs, treatment regimens, and host-directed therapies. AB - Tuberculosis remains the world's leading cause of death from an infectious disease, responsible for an estimated 1 674 000 deaths annually. WHO estimated 600 000 cases of rifampicin-resistant tuberculosis in 2016-of which 490 000 were multidrug resistant (MDR), with less than 50% survival after receiving recommended treatment regimens. Concerted efforts of stakeholders, advocates, and researchers are advancing further development of shorter course, more effective, safer, and better tolerated treatment regimens. We review the developmental pipeline and landscape of new and repurposed tuberculosis drugs, treatment regimens, and host-directed therapies (HDTs) for drug-sensitive and drug resistant tuberculosis. 14 candidate drugs for drug-susceptible, drug-resistant, and latent tuberculosis are in clinical stages of drug development; nine are novel in phase 1 and 2 trials, and three new drugs are in advanced stages of development for MDR tuberculosis. Specific updates are provided on clinical trials of bedaquiline, delamanid, pretomanid, and other licensed or repurposed drugs that are undergoing investigation, including trials aimed at shortening duration of tuberculosis treatment, improving treatment outcomes and patient adherence, and reducing toxic effects. Ongoing clinical trials for shortening tuberculosis treatment duration, improving treatment outcomes in MDR tuberculosis, and preventing disease in people with latent tuberculosis infection are reviewed. A range of HDTs and immune-based treatments are under investigation as adjunctive therapy for shortening duration of therapy, preventing permanent lung injury, and improving treatment outcomes of MDR tuberculosis. We discuss the HDT development pipeline, ongoing clinical trials, and translational research efforts for adjunct tuberculosis treatment. PMID- 29580820 TI - Plant food allergy: Influence of chemicals on plant allergens. AB - Plant-derived foods are the most common allergenic sources in adulthood. Owing to the rapidly increasing prevalence of plant food allergies in industrialized countries, the environmental factors are suspected to play a key role in development of allergic sensitization. The present article provides an overview of ways by which chemicals may influence the development and severity of allergic reactions to plant foods, with especial focus on plant allergens up-regulated under chemical stress. In plants, a substantial part of allergens have defense related function and their expression is highly influenced by environmental stress and diseases. Pathogenesis-related proteins (PR) account for about 25% of plant food allergens and some are responsible for extensive cross-reactions between plant-derived foods, pollen and latex allergens. Chemicals released by anthropogenic sources such as agriculture, industrial activities and traffic related air pollutants are potential drivers of the increasing sensitization to allergenic PRs by elevating their expression and by altering their immunogenicity through post-translational modifications. In addition, some orally-taken chemicals may act as immune adjuvants or directly trigger non-IgE mediated food allergy. Taken together, the current literature provides an overwhelming body of evidence supporting the fact that plant chemical exposure and chemicals in diet may enhance the allergenic properties of certain plant-derived foods. PMID- 29580821 TI - PAHs in seafood from the Mediterranean Sea: An exposure risk assessment. AB - Seafood represent an important food source for human, and seafood quality is associated with marine environment quality. PAHs are one of the main organic environmental contaminants and they can be introduced into the body through different way (ingestion, inhalation, dermal absorption). We present data on bioaccumulation of the sixteen PAHs, defined priority by the U.S.- EPA, in Sardina pilchardus, Solea solea and Donax trunculus, three species caught in the Catania Gulf and highly consumed by the local population. The risk to develop chronic systemic and carcinogenic effects due to the consumption of these target species was evaluated through the EDI, THQ and CR. EDI derived from D. trunculus ingestion falls within the range calculated by the EFSA. The THQ is less than 1, and the CR calculated for the Benzo(a)Pyrene is at the limit of the ARL (1?10-5). EDI derived from S. pilchardus and S. solea ingestion are below the range calculated by the EFSA. The THQ is less than 1, and the CR is below the acceptable risk level. The contamination level found in local seafood determines a low risk to develop chronic systemic effects, but the cancer risk could be of health concern especially for high-frequency molluscs consumers. PMID- 29580822 TI - Dietary exposure to cadmium and health risk assessment in children - Results of the French infant total diet study. AB - Besides specific occupational activities or smoking, food is the main route of cadmium exposure for the general population. In France a total diet study previously conducted for adults and children over 3 years old revealed that health concerns due to Cd dietary exposure existed for both adults and children. This study showed that the Cd tolerable weekly intake, based on potential nephrotoxicity effects, is exceeded by a high proportion of children under 3 years old. Nephrotoxicity results from the accumulation of cadmium in the kidney and appears typically after long-term exposure (40-50 years). Despite the exceeding of the tolerable weekly intake observed during the first three years of childhood, due to low body weights compared to adults, the accumulation rate of cadmium is much lower during the whole childhood period (from 0 to 17 years of age) than during adulthood. These data suggest that dietary exposure to cadmium should be reduced for both children and adults to prevent health concerns associated with nephrotoxicity in later life. Moreover, recent literature suggests that Cd can induce other adverse health effects (especially endocrine disruption or neurotoxicity) that could be triggered at even lower doses than those triggering nephrotoxicity. PMID- 29580823 TI - GW0742 (PPAR-beta agonist) attenuates hepatic endoplasmic reticulum stress by improving hepatic energy metabolism in high-fat diet fed mice. AB - Endoplasmic reticulum (ER) stress and hepatic steatosis are intertwined with insulin resistance. PPARs are at the crossroads of these pathways. This study aimed to investigate the effects of GW0742 (PPAR-beta agonist) on hepatic energy metabolism and ER stress in a murine diet-induced obesity model. HF diet caused overweight, hyperinsulinemia, hepatic inflammation (increased NF-kB, TNF-alpha, and IL-6 protein expression) and favored hepatic lipogenesis, leading to ER stress, with ultrastructural and molecular alterations, ending up in proapoptotic stimulus. GW0742 rescued the overweight and the glucose tolerance, tackled hepatic inflammation and favored hepatic beta-oxidation over lipogenesis. These results comply with ER ultrastructure improvement, reducing ER stress and apoptosis in treated animals. Our results indicate that the PPAR-beta/delta activation alleviated the ER stress by improving the insulin sensitivity and maximizing the hepatic energy metabolism with a shift towards beta-oxidation. PPAR-beta/delta activation could be an essential tool to avoid the NAFLD progression and other obesity constraints. PMID- 29580824 TI - ESR2 regulates granulosa cell genes essential for follicle maturation and ovulation. AB - Estrogen receptor 2 (ESR2) plays a critical role in folliculogenesis and ovulation. Disruption of ESR2-function in the rats results in female infertility due to failure of ovulation. Ovulation failure occurred in two distinct rat models, a null mutant and a DNA binding domain (DBD) mutant of ESR2, indicating that transcriptional regulation by ESR2 is indispensable for ovulation. To define the regulatory role of ESR2 in preovulatory follicular maturation and ovulation, we investigated ovarian responsiveness to exogenous gonadotropins in prepubertal females. Granulosa cells (GCs) play a vital role in follicle maturation and ovulation, and ESR2-dependent estrogen signaling is predominant in GCs, therefore, we examined the differential expression of gonadotropin-induced genes in GCs. Of 32,623 genes detected by RNA-sequencing, 1696 were differentially expressed in Esr2-mutant rats (789 downregulated, and 907 upregulated, absolute fold change 2, FDR p < 0.05). Molecular pathway analyses indicated that these differentially expressed genes are involved in steroidogenesis, follicle maturation, and ovulation. Many of these genes are known regulators of ovarian function and a subset were also disrupted in Esr2-mutant mice. Interestingly, Kiss1 was identified as one of the differentially expressed genes implicating a potential role within the follicle and its regulation by ESR2. Our findings indicate that ESR2 regulates key genes in GCs that are essential for follicle maturation and ovulation in the rat. PMID- 29580825 TI - PIWI-piRNA pathway: Setting the pace of aging by reducing DNA damage. AB - Transposable elements (TEs) are powerful drivers of genome evolutionary dynamics but are principally deleterious to the host organism by compromising the integrity and function of the genome. The transposition of TEs may result in mutations and DNA damage. DNA double-strand breaks (DSBs), which may be caused by the transposition, are one of the processes directly linked to aging. TEs may thus be considered to constitute an internal source of aging and the frequency of transposition may, in turn, be considered to affect the pace of aging. The PIWI piRNA pathway is a widespread strategy used by most animals to effectively suppress transposition. Interestingly, the PIWI-piRNA pathway is expressed predominantly in the animal germline, a more or less continuous immortal lineage set aside after the first few cell divisions of a developing embryo. Recent findings further imply that the PIWI-piRNA pathway and TE suppression constitute an important mechanism regulating aging. This article discusses the proposed role of the PIWI-piRNA pathway in setting the pace of aging as well as the possible mechanisms underlying this process. PMID- 29580826 TI - Protein aggregates and proteostasis in aging: Amylin and beta-cell function. AB - The ubiquitin-proteasomal-system (UPS) and the autophagy-lysosomal-system (ALS) are both highly susceptible for disturbances leading to the accumulation of cellular damage. A decline of protein degradation during aging results in the formation of oxidatively damaged and aggregated proteins finally resulting in failure of cellular functionality. Besides protein aggregation in response to oxidative damage, amyloids are a different type of protein aggregates able to distract proteostasis and interfere with cellular functionality. Amyloids are clearly linked to the pathogenesis of age-related degenerative diseases such as Alzheimer's disease. Human amylin is one of the peptides forming fibrils in beta sheet conformation finally leading to amyloid formation. In contrast to rodent amylin, human amylin is prone to form amyloidogenic aggregates, proposed to play a role in the pathogenesis of Type 2 Diabetes by impairing beta-cell functionality. Since aggregates such as lipofuscin and beta-amyloid are known to impair proteostasis, it is likely to assume similar effects for human amylin. In this review, we focus on the effects of IAPP on UPS and ALS and their role in amylin degradation, since both systems play a crucial role in maintaining proteome balance thereby influencing, at least in part, cellular fate and aging. PMID- 29580827 TI - Dual antiplatelet therapy versus single antiplatelet therapy after transaortic valve replacement: Meta-analysis. AB - BACKGROUND: The current guidelines recommend empirical therapy with DAPT of aspirin and clopidogrel for six months after TAVR. This recommendation is based on expert consensus only. Giving the lack of clear consensus on treatment strategy following TAVR. Goal of this meta-analysis is to assess the efficacy and safety of mono-antiplatelet therapy (MAPT) versus dual antiplatelet therapy (DAPT) following transcatheter aortic valve replacement (TAVR). METHODS AND MATERIALS: We performed a meta-analysis from randomized clinical trials (RCTs) and prospective studies that tested DAPT vs. MAPT for all-cause mortality and major bleeding of 603 patients. The primary efficacy outcomes were 30 days mortality and stroke. The primary safety outcomes were major bleeding and major vascular complications. RESULTS: We included 603 patients from 4 studies. The use of MAPT was associated with similar mortality rate (5.9% vs. 6.6%; RR = 0.92; 95% CI 0.49-1.71; P = 0.68) and stroke rate compared with DAPT (1.3% vs. 1.3%; RR 1.04; 95% CI 0.27 to 4.04; P = 0.81). There was no difference in major vascular complication (4.2% vs. 8.9%; RR 0.52; 95% CI 0.23 to 1.18; P = 0.17) or minor vascular complication (4.2% vs. 7.3%; RR 0.58; 95% CI 0.25 to 1.34; P = 0.14). However, MAPT was associated with significantly less risk of major bleeding (4.9% vs. 14.5%; RR 0.37; 95% CI 0.20 to 0.70; P < 0.01) but no difference in minor bleeding (4.2% vs. 3.6%; RR 1.16; 95% CI 0.43 to 3.10; P = 0.85). CONCLUSION: MAPT use after TAVR is associated with lower rates of major bleeding compared with DAPT with no significant difference in mortality, stroke or vascular complications. PMID- 29580828 TI - Continuous glucose monitoring abnormalities in cystic fibrosis youth correlate with pulmonary function decline. AB - BACKGROUND: To characterize glucose patterns with continuous glucose monitoring (CGM) in cystic fibrosis (CF) and assess relationships between CGM and clinical outcomes. METHODS: 110 CF youth and healthy controls (HC), 10-18 years, wore CGM up to 7 days. Correlations between CGM and lung function and BMI z-score change over the prior year were determined. RESULTS: Multiple CGM measures were higher in CF Normal Glycemic (CFNG) youth versus HC (peak glucose, excursions >140 mg/dl/day, %time > 140 mg/dl, standard deviation (SD) and mean amplitude of glycemic excursions (MAGE)). Hypoglycemia was no different among groups. In CF, decline in FEV1% and FVC% correlated with maximum CGM glucose, excursions >200 mg/dl/day, SD, and MAGE. CONCLUSIONS: CFNG youth have higher glucoses and glucose variability than HC on CGM. Higher and more variable glucoses correlate with lung function decline. Whether earlier treatment of CGM abnormalities improves lung function in CF requires further study. PMID- 29580829 TI - Sweat test for cystic fibrosis: Wearable sweat sensor vs. standard laboratory test. AB - BACKGROUND: Sweat chloride testing for diagnosis of cystic fibrosis (CF) involves sweat induction, collection and handling, and measurement in an analytical lab. We have developed a wearable sensor with an integrated salt bridge for real-time measurement of sweat chloride concentration. Here, in a proof-of-concept study, we compare the performance of the sensor to current clinical practice in CF patients and healthy subjects. METHOD: Sweat was induced on both forearms of 10 individuals with CF and 10 healthy subjects using pilocarpine iontophoresis. A Macroduct sweat collection device was attached to one arm and sweat was collected for 30 min and then sent for laboratory analysis. A sensor was attached to the other arm and the chloride ion concentration monitored in real time for 30 min using a Bluetooth transceiver and smart phone app. RESULTS: Stable sweat chloride measurements were obtained within 15 min following sweat induction using the wearable sensor. We define the detection time as the time at which the standard deviation of the real-time chloride ion concentration remained below 2 mEq/L for 5 min. The sweat volume for sensor measurements at the detection time was 13.1 +/ 11.4 MUL (SD), in many cases lower than the minimum sweat volume of 15 MUL for conventional testing. The mean difference between sweat chloride concentrations measured by the sensor and the conventional laboratory practice was 6.2 +/- 9.5 mEq/L (SD), close to the arm-to-arm variation of about 3 mEq/L. The Pearson correlation coefficient between the two measurements was 0.97 highlighting the excellent agreement between the two methods. CONCLUSION: A wearable sensor can be used to make real-time measurements of sweat chloride within 15 min following sweat induction, requiring a small sweat volume, and with excellent agreement to standard methods.

PMID- 29580830 TI - Myocardial Injury is More Common than Deep Venous Thrombosis after Vascular Surgery and is Associated with a High One Year Mortality Risk. AB - OBJECTIVE/BACKGROUND: Venous thromboembolism (VTE) has been considered the dominant major life threatening vascular complication after non-cardiac surgery, but recent studies have shifted the emphasis toward myocardial injury after non cardiac surgery (MINS) as a common adverse event in the peri-operative setting. The aim of the present study was to compare the incidence and influence on mortality of two dominant venous and arterial events in the peri-operative period by prospectively screening a consecutive cohort of patients undergoing vascular surgery. METHODS: This was a sub-study of Vascular Events In Non-cardiac Surgery Patients Cohort Evaluation (VISION), the main objective of which was to evaluate major peri-operative complications after non-cardiac surgery. Patients undergoing vascular surgery had their blood collected to measure the Roche fifth generation high sensitivity troponin T (hsTnT) assay before and four times after surgery (6 12 h post-operatively, on the first, second, and third day following the procedure). MINS was defined as an elevated post-operative hsTnT >=65 ng/L or an hsTnT >=20 to <65 ng/L with an absolute change of >=5 ng/L that was judged to be due to ischaemia. All patients underwent ultrasound venous compression testing for deep vein thrombosis (DVT) before, 4, and 7 days after surgery and follow-up was performed by telephone 30 days and 1 year after surgery. RESULTS: In total, 164 consecutive patients were included in this sub-study. MINS was diagnosed in 39 patients (23.8%) and DVT in four patients (2.4%). The 1 year mortality was higher in MINS (9/39 [23.1%]) than non-MINS patients (9/125 [7.2%]; p = .006). None of the patients who developed DVT died in the first year after surgery. CONCLUSION: MINS is a common complication after vascular surgery. It occurs more frequently than DVT and is associated with high 1 year mortality.

PMID- 29580833 TI - Association between physical activity and walking capacity with cognitive function in peripheral artery disease patients. AB - OBJECTIVE: To identify the association between objectively measured physical activity and walking capacity with cognitive function in patients with symptomatic peripheral artery disease. METHODS: This was an observational, cross sectional study. One hundred and thirty patients (age 67 +/- 8 years) were recruited at a tertiary centre specializing in vascular disease. Cognitive function (global, memory, executive function and attention) was evaluated using the Montreal Cognitive Assessment tool. Physical activity levels (total, light, and moderate-vigorous) were obtained using an accelerometer. A 6 min and 4 m walk test were undertaken to assess walking capacity. Crude and covariate adjusted, linear regression analyses confirmed significant associations between physical activity levels and walking capacity with cognitive function. RESULTS: Positive and significant associations were observed between moderate to vigorous physical activity (p = .039) and walking capacity (p = .030) with memory after adjusting for covariates. No significant association was identified between light physical activity and usual gait speed with any cognitive function outcome. CONCLUSION: Greater memory performance was associated with greater moderate to vigorous physical activity levels and walking capacity in patients with symptomatic peripheral artery disease. Clinical interventions focused on improving moderate to vigorous physical activity levels and walking capacity may provide important therapies to potentially enhance cognitive health in patients with peripheral artery disease. PMID- 29580834 TI - Niemann-Pick C2 protein regulates sterol transport between plasma membrane and late endosomes in human fibroblasts. AB - Niemann-Pick disease type C2 is a lipid storage disorder in which mutations in the NPC2 protein cause accumulation of lipoprotein-derived cholesterol in late endosomes and lysosomes (LE/LYSs). Whether cholesterol delivered by other means to NPC2 deficient cells also accumulates in LE/LYSs is currently unknown. We show that the close cholesterol analog dehydroergosterol (DHE), when delivered to the plasma membrane (PM) accumulates in LE/LYSs of human fibroblasts lacking functional NPC2. We measured two different time scales of sterol diffusion; while DHE rich LE/LYSs moved by slow anomalous diffusion in disease cells (D ~ 4.6?10-4 MUm2/sec; alpha~0.76), a small pool of sterol could exchange rapidly with D ~ 3 MUm2/s between LE/LYSs, as shown by fluorescence recovery after photobleaching (FRAP). By quantitative lipid mass spectrometry we found that esterification of 13C-labeled cholesterol but not of DHE is reduced 10-fold in disease fibroblasts compared to control cells. Internalized NPC2 rescued the sterol storage phenotype and strongly expanded the dynamic sterol pool seen in FRAP experiments. Together, our study shows that cholesterol esterification and trafficking of sterols between the PM and LE/LYSs depends on a functional NPC2 protein. NPC2 likely acts inside LE/LYSs from where it increases non-vesicular sterol exchange with other organelles. PMID- 29580835 TI - Implications of the Mediterranean diet and physical exercise on the lipid profile of metabolically healthy obese women as measured by nuclear magnetic resonance spectroscopy (1H NMR). AB - OBJECTIVE: There is a lack of consensus when it comes to establishing the biochemical parameters that define metabolically healthy obese (MHO) subjects. Indeed, most studies do not include subjects' lipid profiles. Our objective was to characterize lipoprotein size, particle and subclass concentration using 1H NMR in MHO women after two years of weight loss with a hypocaloric Mediterranean diet and physical exercise. METHODS: 115 non-diabetic women (aged 35-55 years) with a body mass index (BMI) of 30-40 kg/m2 and <=1 of the following criteria: blood pressure >=135/85 mmHg, fasting plasma glucose >=100 mg/dL, HDL cholesterol <=50 mg/dL and triglycerides >=150 mg/dL were included. After two years of intensive lifestyle modification (Mediterranean diet and physical exercise), they were classified according to their weight loss: <5%, >=5%-<10% and >=10%. Lipoprotein size, particle and subclass concentrations were measured using 1H NMR. RESULTS: The final population, after dropouts, were 67 women (age: 44.5 +/- 3.7 years, BMI: 36.3 +/- 4.7 kg/m2), of whom 23 (38.3%) lost <5%, and 22 (36.7%), lost >=5% to <10% and >=10% of baseline body weight, respectively. The lipid profile showed no significant changes after intervention, especially in small LDL particles or in production of HDL. The diameter of LDL and HDL particles did not change after two years of a Mediterranean diet and physical exercise. CONCLUSION: These results indicate that intensive lifestyle modification does not produce significant changes in the lipid profile of MHO women. Levels of more atherogenic or atheroprotective particles did not change after two years, despite the intervention. PMID- 29580836 TI - Differential expression of two Piwil orthologs during embryonic and gonadal development in pufferfish, Takifugu fasciatus. AB - Piwil was an important regulator gene in germ cell division during gonadal development. Two Piwi-like genes, Piwil1 and Piwil2, were first cloned from T. fasciatus. The full-length cDNAs of Piwil1 and Piwil2 were of 2933 and 3394 bp, respectively. Piwil1 and Piwil2 possessed an open reading frame (ORF) of 2565 and 3138 bp, encoding 854 and 1045 amino acids, respectively. The tissue distribution analysis demonstrated that Piwil1 and Piwil2 were expressed at higher levels in gonad compared to other tissues (brain, liver, gill, etc.). The time-course dynamic expressions of Piwils during embryonic indicated that Piwil1 and Piwil2 were mainly enriched in the early embryonic development. In testis, the expression of Piwil1 and Piwil2 increased at first but then decreased at mRNA and protein levels. However, the expression of Piwil1 and Piwil2 in the ovary showed a downward trend from the beginning. In addition, the expression levels of Piwil1 and Piwil2 were weak in mature testes or ovaries. The immunohistochemistry analysis revealed that Piwil1 and Piwil2 were abundantly expressed in cytoplasm of spermatogonia, spermatocytes, oocyte I and oocytes II, which were mainly presented in the early stages of gonadal development. Our results suggested that Piwil was related to the differentiation of germ cells, and might play an important role in embryonic development. Therefore, our findings provided valuable information of Piwils in the reproductive cycle of T. fasciatus. PMID- 29580837 TI - Identification and characterization of two distinct sigma-class glutathione-S transferase from freshwater bivalve Cristaria plicata. AB - Glutathione-S-transferases (GSTs) are multifunctional phase II detoxification enzymes that catalyze the attachment of electrophilic substrates to glutathione, and play an important role in protecting organisms against the toxicity of reactive oxygen species. In this study, two distinct sigma-class GST (CpGSTsigma1 and 2) cDNA sequences were cloned from freshwater bivalve Cristaria plicata. The full length cDNA of CpGSTsigma1 and 2 was 826 bp and 1609 bp, which encoded 213 and 248 amino acid residues, respectively. Their transcripts were expressed in all detected tissues and the highest expression level was in hepatopancreas from C. plicata. The expression level of CpGSTsigma1 and 2 in hepatopancreas and hemocytes showed a significantly increased trend after bacterial challenge. The recombinant CpGSTsigma1 was successfully expressed as a soluble form in Escherichia coli DE3. The specific activity of recombinase toward CDNB was 46.965 +/- 0.082 MUmol/min/mg, and its optimum temperature and pH was 37 degrees C and 9.0, respectively. The recombinant of CpGSTsigma1 could bear 6 M urea and 8% SDS, when the concentration of urea was 8 M and its activity was only below 20%. The results might provide a better perspective on the mechanisms of resistance to bacterial infection in molluscs. PMID- 29580838 TI - Tackling mortality due to childhood tuberculosis. PMID- 29580839 TI - The now and then of gut-brain signaling. AB - Since their very beginnings, animals had gut sensory epithelial cells. In one of the first multicellular animals, Trichoplax - a literal wandering gut - food sensing and feeding was coordinated by specialized ventral sensor cells. In mammals, including humans, gut epithelial sensor cells (a.k.a enteroendocrine cells) have been recognized for an array of neuropeptides, like ghrelin and cholecystokinin, that modulate hunger or satiety. Indeed, since first described as "clear cells" by Rudfolf Heidenhain (1868), research efforts increasingly focused on their hormone neuropeptides leading to the alphabetical classification of one cell-one hormone (e.g. I-cell synthesizes only cholecystokinin). A recent explosion of molecular tools to study the biology of single cells is expanding the imagination of studies and unveiling intriguing aspects of gut sensory transduction. To mention a few: multimodal sensing, one cell expressing both ghrelin and cholecystokinin-the yin and yang of appetite-, and synapses with nerves. This brief account examines recent advances on gut sensory transduction to highlight how food and bacteria in the gut alter eating. PMID- 29580840 TI - HIV-1 Promotes the Degradation of Components of the Type 1 IFN JAK/STAT Pathway and Blocks Anti-viral ISG Induction. AB - Anti-retroviral therapy successfully suppresses HIV-1 infection, but fails to provide a cure. During infection Type 1 IFNs normally play an essential role in viral clearance, but in vivo IFN-alpha only has a modest impact on HIV-1 infection, suggesting its possible targeting by HIV. Here, we report that the HIV protein, Vif, inhibits effective IFN-alpha signalling via degradation of essential JAK/STAT pathway components. We found that STAT1 and STAT3 are specifically reduced in HEK293T cells expressing Vif and that full length, infectious HIV-1 IIIB strain promotes their degradation in a Vif-dependent manner. HIV-1 IIIB infection of myeloid ThP-1 cells also reduced the IFN-alpha mediated induction of the anti-viral gene, ISG15, but not MxA, revealing a functional consequence of this HIV-1-mediated immune evasion strategy. Interestingly, while total STAT levels were not reduced upon in vitro IIIB infection of primary human PBMCs, IFN-alpha-mediated phosphorylation of STAT1 and STAT3 and ISG induction were starkly reduced, with removal of Vif (IIIBDeltaVif), partially restoring pSTATs, ISG15 and MxB induction. Similarly, pSTAT1 and pSTAT3 expression and IFN-alpha-induced ISG15 were reduced in PBMCs from HIV-infected patients, compared to healthy controls. Furthermore, IFN-alpha pre-treatment of a CEM T lymphoblast cells significantly inhibited HIV infection/replication (measured by cellular p24), only in the absence of Vif (IIIBDeltaVif), but was unable to suppress full length IIIB infection. When analysing the mechanism by which Vif might target the JAK/STAT pathway, we found Vif interacts with both STAT1 and STAT3, (but not STAT2), and its expression promotes ubiquitination and MG132-sensitive, proteosomal degradation of both proteins. Vif's Elongin-Cullin SOCS-box binding motif enables the formation of an active E3 ligase complex, which we found to be required for Vif's degradation of STAT1 and STAT3. In fact, the E3 ligase scaffold proteins, Cul5 and Rbx2, were also found to be essential for Vif-mediated proteasomal degradation of STAT1 and STAT3. These results reveal a target for HIV-1-Vif and demonstrate how HIV-1 impairs the anti-viral activity of Type 1 IFNs, possibly explaining why both endogenous and therapeutic IFN-alpha fail to activate more effective control over HIV infection. PMID- 29580841 TI - Long Non-Coding RNAs Associated with Metabolic Traits in Human White Adipose Tissue. AB - Long non-coding RNAs (lncRNAs) belong to a recently discovered class of molecules proposed to regulate various cellular processes. Here, we systematically analyzed their expression in human subcutaneous white adipose tissue (WAT) and found that a limited set was differentially expressed in obesity and/or the insulin resistant state. Two lncRNAs herein termed adipocyte-specific metabolic related lncRNAs, ASMER-1 and ASMER-2 were enriched in adipocytes and regulated by both obesity and insulin resistance. Knockdown of either ASMER-1 or ASMER-2 by antisense oligonucleotides in in vitro differentiated human adipocytes revealed that both genes regulated adipogenesis, lipid mobilization and adiponectin secretion. The observed effects could be attributed to crosstalk between ASMERs and genes within the master regulatory pathways for adipocyte function including PPARG and INSR. Altogether, our data demonstrate that lncRNAs are modulators of the metabolic and secretory functions in human fat cells and provide an emerging link between WAT and common metabolic conditions. PMID- 29580843 TI - In-clinic secondary tracheoesophageal puncture and voice prosthesis placement in laryngectomees. AB - Secondary tracheoesophageal puncture (TEP) with voice prosthesis placement represents one of the possibility to restore vocal function after total laryngectomy. However, some patients have comorbidities that contraindicate general anesthesia. In our department, an in-clinic TEP procedure for retrograde voice prosthesis placement was developed. It allows the immediate placement of the prosthesis and the avoidance of the use of dilators. We described our technique with advantages and pitfalls. The Provox Vega Puncture Set was used. Our technique for in-clinic secondary TEP without general anesthesia or target controlled infusion was a safe and effective procedure. It allows the use of the traditional TEP set, with possibility of voice prosthesis placement after previous TEP closure. PMID- 29580842 TI - MARCKSL1 Regulates Spine Formation in the Amygdala and Controls the Hypothalamic Pituitary-Adrenal Axis and Anxiety-Like Behaviors. AB - Abnormalities in limbic neural circuits have been implicated in the onset of anxiety disorders. However, the molecular pathogenesis underlying anxiety disorders remains poorly elucidated. Here, we demonstrate that myristoylated alanine-rich C-kinase substrate like 1 (MARCKSL1) regulates amygdala circuitry to control the activity of the hypothalamic-pituitary-adrenal (HPA) axis, as well as induces anxiety-like behaviors in mice. MARCKSL1 expression was predominantly localized in the prefrontal cortex (PFC), hypothalamus, hippocampus, and amygdala of the adult mouse brain. MARCKSL1 transgenic (Tg) mice exhibited anxiety-like behaviors dependent on corticotropin-releasing hormone. MARCKSL1 increased spine formation in the central amygdala, and downregulation of MARCKSL1 in the amygdala normalized both increased HPA axis activity and elevated anxiety-like behaviors in Tg mice. Furthermore, MARCKSL1 expression was increased in the PFC and amygdala in a brain injury model associated with anxiety-like behaviors. Our findings suggest that MARCKSL1 expression in the amygdala plays an important role in anxiety-like behaviors. PMID- 29580844 TI - Primary Maxillary Deficiency Dentofacial Deformities: Occlusion and Facial Esthetic Surgical Outcomes. AB - PURPOSE: The purpose of this study was to document the malocclusion and facial dysmorphology in patients with primary maxillary deficiency (PMD) and chronic obstructive nasal breathing before treatment and the outcomes after bimaxillary orthognathic, genioplasty, and intranasal surgery. MATERIALS AND METHODS: A retrospective cohort study of patients with PMD undergoing bimaxillary orthognathic, chin, and intranasal surgery was implemented. The predictor variables were grouped into demographic, anatomic, operative, and longitudinal follow-up categories. The primary outcome variables were the initial postoperative occlusion achieved (T2; 5 weeks postoperatively) and that maintained long-term (T3 or T4; >2 years after surgery). Six occlusion parameters were assessed: overjet, overbite, coincidence of dental midlines, Angle classification, and molar vertical and transverse positions. A second outcome variable was facial esthetic results. Photographs were analyzed to document 7 facial contour characteristics. RESULTS: Sixty-six patients met the inclusion criteria. Age at operation averaged 22 years (15 to 55 yr). The study included 18 women (27%). Most patients (57 of 66; 86%) achieved and maintained a favorable occlusion for each parameter studied long-term (mean, 5 yr). The need for a 3 segment Le Fort I was strongly associated with long-term posterior malocclusion. Facial dysmorphology before surgery included the appearance of a prominent chin (56%), flat labiomental fold (61%), prominent lower lip (88%), prominent nose (77%), sunken midface (100%), flat cheekbones (82%), and recessed upper lip (73%). Before surgery, 82% of patients exhibited at least 5 of the 7 key facial contour deformities. Correction of all 7 facial contour deformities was confirmed in 92% of patients in the long-term. In 8% of patients, an overly prominent appearing chin persisted. CONCLUSION: Using orthognathic techniques, most patients with PMD achieved and maintained a corrected occlusion long-term. In unoperated patients, a "facial esthetic type" was identified. Bimaxillary orthognathic and chin surgery proved effective in correcting associated facial dysmorphology in most patients. PMID- 29580845 TI - Occupational exposure and asthma. PMID- 29580846 TI - Barriers to medication adherence in asthma: The importance of culture and context. AB - OBJECTIVE: Significant disparities exist in asthma outcomes. Racial and ethnic minorities have lower controller medication adherence, which may contribute to differences in asthma morbidity between minority and non-minority groups. The objective of this review is to identify individual, patient-provider communication, and systems issues that contribute to this pattern of medication underuse and to discuss potential strategies for intervention. DATA SOURCES: Data were gathered from numerous sources, including reports of pharmacy and medical records, observational studies, and trials. STUDY SELECTIONS: Studies analyzed factors contributing to patterns of asthma medication adherence that differ by race and ethnicity. RESULTS: There is clear evidence of underuse of asthma controller medications among racial and ethnic minorities in prescription receipt, prescription initiation, and medication use once obtained. Individual factors such as medication beliefs and depressive symptoms play a role. Provider communication is also relevant, including limited discussion of complementary and alternative medicine use, difficulties communicating with patients and caregivers with limited English proficiency, and implicit biases regarding cultural differences. Systems issues (eg, insurance status, cost) and social context factors (eg, exposure to violence) also present challenges. Culturally informed strategies that capitalize on patient strengths and training providers in culturally informed communication strategies hold promise as intervention approaches. CONCLUSION: Disparities in controller medication use are pervasive. Identifying the sources of these disparities is a critical step toward generating intervention approaches to enhance disease management among the groups that bear the greatest asthma burden. PMID- 29580847 TI - Parabens and measures of adiposity among adults and children from the U.S. general population: NHANES 2007-2014. AB - BACKGROUND: Emerging experimental studies suggest that parabens could affect metabolism by altering the microbiome or signaling pathways involved in adipocyte differentiation. While human exposure to parabens is widespread, epidemiologic studies assessing the role of these chemicals on adiposity measures are scarce. OBJECTIVE: We examined associations of parabens with adiposity measures among adults and children in the U.S. general population. METHODS: We conducted covariate-adjusted linear and logistic regression models to examine associations between urinary biomarker concentrations of four parabens (butyl-BP, ethyl-EP, methyl-MP, and propyl paraben-PP) and measures of adiposity (obesity; body mass index, BMI or BMI z-score; and waist circumference) among 4730 adults (2007-2014) and 1324 children (2007-2012), participating in the National Health and Nutrition Examination Survey. We also assessed heterogeneity of associations by gender. RESULTS: We generally observed significant inverse associations between adiposity measures and paraben biomarker concentrations among adults (BP, EP, MP, PP) and children (MP). For example, adjusted prevalence odds ratios (95% confidence intervals, CI) for obesity per a ten-fold increase in MP concentrations were 0.64 (95% CI: 0.55, 0.73) for adults and 0.71(95% CI: 0.52, 0.95) for children. Strength of inverse associations typically increased monotonically with increasing paraben exposure quartiles; and, in general, inverse associations were more pronounced among females. Associations remained when controlling for other phenolic compounds previously linked with adiposity measures. CONCLUSIONS: In this cross-sectional study of adiposity measures and parabens, we observed consistent inverse associations in a representative sample of U.S adults and children. Further studies are warranted to confirm our findings, examine the potential role of paraben sequestration in adipose tissue, and elucidate mechanisms by which parabens could alter metabolism. PMID- 29580848 TI - Human biomonitoring reference values for some non-persistent chemicals in blood and urine derived from the Canadian Health Measures Survey 2009-2013. AB - The Canadian Health Measures Survey collects nationally representative human biomonitoring data on a suite of chemicals and their metabolites, including many non-persistent chemicals. Data has been collected on non-persistent chemicals, including acrylamide, chlorophenols, environmental phenols and triclocarban, organophosphate insecticides, phthalates, polycyclic aromatic hydrocarbon, pyrethroid insecticides, and volatile organic compounds from 2009 to 2013. Using a systematic approach building on the reference interval concept proposed by the International Federation of Clinical Chemistry and Laboratory Medicine and the International Union of Pure and Applied Chemistry, we derive human biomonitoring reference values (RV95s) for these classes of non-persistent chemicals in blood and urine for the general Canadian population. RV95s were derived for biomarkers of non-persistent chemicals with widespread detection in Canadians (>66% detection rate). Samples with urinary creatinine levels outside the recommended range of 0.3-3.0 MUg/L were excluded. Reference populations were constructed by applying smoking and fasting as exclusion criteria where appropriate. Age and sex were evaluated as possible partitioning criteria and separate RV95s were derived for sub-populations in cases where partitioning was deemed necessary. Reference values were derived for 40 biomarkers and represent the first set of RV95s for non-persistent chemicals in the general Canadian population. These values provide a measure of the upper margin of background exposure in the general population and can be compared against individual and population human biomonitoring data. RV95s can be used to by public health officials to identify individuals with high exposures, and by risk assessors and risk managers to identify atypical exposures or subpopulations with elevated exposures. PMID- 29580850 TI - Selective binding and controlled release of anticancer drugs by polyanionic cyclodextrins. AB - The binding stoichiometry, binding constants, and inclusion mode of some water soluble negatively charged cyclodextrin derivatives, i.e. heptakis-[6-deoxy-6-(3 sulfanylpropanoic acid)]-beta-cyclodextrin(H1), heptakis-[6-deoxy-6-(2 sulfanylacetic acid)]-beta-cyclodextrin(H2), mono-[6-deoxy-6-(3-sulfanylpropanoic acid)]-beta-cyclodextrin (H3) and mono-[6-deoxy-6-(2-sulfanylacetic acid)]-beta cyclodextrin (H4), with three anticancer drugs, i.e. irinotecan hydrochloride; topotecan hydrochloride; doxorubicin hydrochloride, were investigated by means of 1H NMR, UV-Vis spectroscopy, mass spectra and 2D NMR. Polyanionic cyclodextrins H1-H2 showed the significantly high binding abilities of up to 2.6 * 104-2.0 * 105 M-1 towards the selected anticancer drugs, which were nearly 50-1000 times higher than the corresponding Ks values of native beta-cyclodextrin. In addition, these polyanionic cyclodextrins also showed the pH-controlled release behaviors. That is, the anticancer drugs could be efficiently encapsulated in the cyclodextrin cavity at a pH value similar to that of serum but sufficiently released at an endosomal pH value of a cancer cell, which would make these cyclodextrin derivatives the potential carriers for anticancer drugs. PMID- 29580849 TI - Synthesis and biological evaluation of aminothiazoles against Histoplasma capsulatum and Cryptococcus neoformans. AB - The design and synthesis of a library of forty novel 2-aminoazole analogues as well as their evaluation as antifungal compounds against Histoplasma capsulatum and Cryptococcus neoformans is described. These structures were derived from N-[5 (1-naphthalenylmethyl)-2-thiazolyl]cyclohexanecarboxamide (41F5), a fungistatic agent previously identified through phenotypic screening (Antimicrob Agents Chemother. 2013;57:4349). Modifications to improve potency and water-solubility of 41F5 focused primarily on the 5-naphthalenyl group, the thiazole core, and the methylene linker between these two structural elements. In general, compounds with lipophilic [5+6] bicyclic ring systems, such as the 7-benzothiophenyl- and 4 indanyl groups, at the 5-position were 2-3 times more active against both fungal species as compared to 41F5. Also, introduction of a carbonyl group at the methylene linker of 41F5 resulted in a 2-3-fold increase in potency. These highly active compounds also showed generally low toxicities against murine P388D1 macrophages resulting in selectivity indices ranging from 63 to >200. Compounds that were highly active against fluconazole-sensitive C. neoformans strains had almost identical activity against fluconazole-resistant variants of this fungus indicating that 14alpha-demethylase is not their molecular target. Highly active compounds also retained activity against H. capsulatum phagocytosed into P388D1 macrophages. PMID- 29580851 TI - Structure-activity relationships of succinimidyl-Cys-C(O)-Glu derivatives with different near-infrared fluorophores as optical imaging probes for prostate specific membrane antigen. AB - Prostate-specific membrane antigen (PSMA), which is overexpressed in malignant prostate cancer (PCa), is an ideal target for imaging and therapy of PCa. We previously reported a PSMA imaging probe, 800CW-SCE, based on succinimidyl-Cys C(O)-Glu (SCE) for optical imaging of PCa. In this study, we investigated the structure-activity relationships of novel SCE derivatives with five different near-infrared (NIR) fluorophores (IRDye 680LT, IRDye 750, Indocyanine Green, Cyanine 5.5, and Cyanine 7) as optical imaging probes targeting PSMA. An in vitro binding assay revealed that 800CW-SCE, 680LT-SCE, and 750-SCE exhibited higher binding affinity than 2-PMPA, which is known as a PSMA inhibitor. These three SCE derivatives were internalized into PSMA-positive cells (LNCaP cells) but not into PSMA-negative cells (PC-3 cells). In the in vivo imaging study, 800CW-SCE and 750 SCE were highly accumulated in LNCaP tumors but not in PC-3 tumors, and the ratio of LNCaP/PC-3 accumulation of 800CW-SCE was higher than that of 750-SCE. The present study may provide valuable molecular design information for the future development of new PSMA imaging probes based on the SCE scaffold. PMID- 29580852 TI - Modelling low pathogenic avian influenza introduction into the commercial poultry industry. AB - Outbreaks of highly pathogenic avian influenza (HPAI) in commercial poultry flocks are rare but highly disruptive to the industry. There is evidence that low pathogenic avian influenza (LPAI) can transfer from wild birds to domestic flocks, where it may mutate to HPAI, and the industry is concerned that an increasing demand for free-range produce may affect the risk of LPAI and HPAI outbreaks. In this paper we focus on LPAI introduction and establishment, and formulate a branching process model to compare risk between sectors and their contribution to overall industry-level risk. Our aim is to determine how heterogeneity in avian influenza viruses and the distinct population structures of each sector - caged, barn and free-range, meat and layer - interact with a continuous risk of virus introduction to affect outbreak probabilities. We show that free-range access is the most influential driver of LPAI outbreaks, with production cycle length having relatively little effect. We demonstrate that variation in virus transmission rates is particularly important when modelling avian influenza introduction to domestic poultry. Virus-free status is of interest for biosecurity and we distinguish how it differs from the usual probability of extinction, and discuss how production cycle length affects this difference. We also use the nonlinear relationship between shed size and risk to identify conditions for which shed size is most influential. PMID- 29580853 TI - FEM simulation of EM field effect on body tissues with bio-nanofluid (blood with nanoparticles) for nanoparticle mediated hyperthermia. AB - The study of temperature profiles and heat transport within the human body when subjected to electromagnetic waves is crucial for development and improvement of radiofrequency hyperthermia treatments. These treatments being minimally invasive can be a better alternative over surgery and chemotherapy for treatment of cancer. Nanoparticle-mediated hyperthermia for cancer therapy is a growing area of cancer nanomedicine because of the potential for localized and targeted destruction of cancer cells. This treatment is dependent on many factors, including thermal conductivity of bio-nanofluid, volume fraction of nanoparticles,excitation wavelength and power and metabolic heat generation. The present study employs Finite Element Method to investigate and optimize the effects of these parameters on temperature distributions and discuss the heat transport within the human body injected with nanoparticles and subjected to electromagnetic waves. The LTNE (Local Thermal Non Equilibrium) model is used to characterize the bioheat transport through the biological medium. In order to understand the effects induced by imposed electromagnetic field, the specific absorption rate (SAR) of body tissues is also studied. The results obtained have been validated against the pertinent numerical results in the literature. This study provides benchmark numerical solutions for heat transport through biological media thereby, helping in understanding the thermophysiologic response of bio-nanofluid towards imposed electromagnetic radiation. PMID- 29580854 TI - Metabolomics-based evidence of the hypoglycemic effect of Ge-Gen-Jiao-Tai-Wan in type 2 diabetic rats via UHPLC-QTOF/MS analysis. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Ge-Gen-Jiao-Tai-Wan (GGJTW) formula, derived from traditional Chinese herbal medicine, is composed of Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep (Ge-Gen in Chinese), Coptis chinensis Franch (Huang Lian), and Cinnamomum cassia (L.) J. Presl (Rou-Gui). GGJTW is used for treatment of diabetes in China, reflecting the potent hypoglycemic effect of its ingredients. However, little is known of the hypoglycemic effect of GGJTW and the underlying metabolic mechanism. AIM OF THE STUDY: This study aimed to investigate the hypoglycemic effect of GGJTW in type 2 diabetic rats and the metabolic mechanism of action. MATERIALS AND METHODS: Ultra high-performance liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry (UHPLC-QTOF/MS)-based metabolomics approach was used for monitoring hyperglycaemia induced by high-sugar high-fat fodder and streptozotocin (STZ), and the protective effect of GGJTW. Dynamic fasting blood glucose (FBG) levels, body weight, and biochemical parameters, including lipid levels, hepatic-renal function, and hepatic histopathology were used to confirm the hyperglycaemic toxicity and attenuation effects. An orthogonal partial least squared discriminant analysis (OPLS-DA) approach highlighted significant differences in the metabolome of the healthy control, diabetic, and drug-treated rats. The metabolomics pathway analysis (MetPA) and Kyoto encyclopedia of genes and genomes (KEGG) database were used to investigate the underlying metabolic pathways. RESULTS: Metabolic profiling revealed 37 metabolites as the most potential biomarker metabolites distinguishing GGJTW-treated rats from model rats. Most of the metabolites were primarily associated with bile acid metabolism and lipid metabolism. The most critical pathway was primary bile acid biosynthesis pathway involving the up-regulation of the levels of cholic acid (CA), chenodeoxycholic acid (CDCA), taurocholic acid (TCA), glycocholic acid (GCA), taurochenodesoxycholic acid (TCDCA), and taurine. CONCLUSIONS: The significantly altered metabolite levels indicated the hypoglycemic effect of GGJTW on diabetic rats and the underlying metabolic mechanism. This study will be meaningful for the clinical application of GGJTW and valuable for further exploration of the mechanism. PMID- 29580855 TI - Statin therapy is associated with higher long-term but not perioperative survival after abdominal aortic aneurysm repair. AB - BACKGROUND: Although preoperative and perioperative statin therapy improves postoperative outcomes in several populations, few data examine its association with survival after abdominal aortic aneurysm (AAA) repair. In addition, no data exist regarding the benefits of starting statins in patients with AAA not currently taking them. METHODS: We performed a registry-based study of all patients undergoing repair of AAAs in the Vascular Quality Initiative between 2003 and 2017 without documented statin intolerance. In our primary analysis, we evaluated the association between preoperative statin therapy and long-term mortality, 30-day mortality, and in-hospital myocardial infarction and stroke. As a secondary analysis, we studied the cohort of patients not taking a statin preoperatively and compared their long-term mortality on the basis of whether they were discharged on a statin. To account for nonrandom assignment to treatment, we constructed propensity scores and applied inverse probability weighting. RESULTS: We identified 40,452 AAA repairs, of which 37,950 fit our entry criteria (29,257 endovascular and 8693 open). Overall, 25,997 patients (69%) were taking a statin preoperatively, with patients undergoing endovascular aneurysm repair more frequently taking a statin than those undergoing open repair (69% compared with 66%; P < .001). After propensity weighting, preoperative statin therapy was not associated with 30-day death or in-hospital stroke or myocardial infarction. However, patients taking statins preoperatively experienced higher adjusted 1-year (94% vs 90%) and 5-year (85% vs 81%) survival from the date of surgery compared with those who were not (P < .001 overall), although subgroup analysis showed that this applied only to intact or symptomatic aneurysms. Of the 11,941 patients not taking a statin preoperatively and discharged alive, 2910 (24%) started on a statin before discharge. In our secondary analysis of the subset of patients not taking statins preoperatively, those initiated on a statin before discharge experienced higher survival at 1 year (94% vs 91%) and 5 years (89% vs 81%; P < .001 overall) than those who remained off statin therapy, with the greatest absolute long-term survival difference in patients with rupture (87% vs 62%; P < .001 overall). CONCLUSIONS: Preoperative statin therapy is associated with higher long-term survival but not perioperative mortality and morbidity in patients undergoing AAA repair, and initiating statin therapy in previously statin-naive patients is associated with markedly higher survival. All patients with AAAs without contraindications should receive statin therapy. In patients not taking a statin at the time of AAA repair, clinicians should consider initiating one before discharge. PMID- 29580856 TI - Induction of inosine triphosphatase activity during ribavirin treatment for chronic hepatitis C. AB - BACKGROUND: Ribavirin (RBV) is an antiviral agent and the primary component for chronic hepatitis C (CHC) therapy. Hemolytic anemia is limitation for RBV treatment. Inosine triphosphatase (ITPA) activity has been associated with severity of RBV-induced anemia. However, changes in ITPA activity during CHC therapy are unknown. The aim of this study was to measure the time-dependent change in ITPA activity over the RBV treatment. METHODS: Forty-two patients with CHC were evaluated for ITPA activity over the course of RBV treatment. RESULTS: The median value of ITPA activity at start of RBV treatment was 134.2 MUmol/h/g hemoglobin (Hb; range, 26.3-251.0 MUmol/h/g Hb). The ITPA activity values at 4, 8, and 12 weeks during RBV treatment were 143.2, 202.2, and 225.7 MUmol/h/g Hb, respectively, and these ITPA values were significantly elevated compared with the start of treatment (p < 0.001). In patients with ITPA variants, patients with anemia (Hb < 10 g/dL) had greater elevated ITPA activities compared with patients without anemia at 12 weeks. CONCLUSION: Our findings indicate that ITPA activities are elevated with RBV therapy, and this elevation may be a risk of anemia in late therapeutic phase in patients that began with low ITPA activity. PMID- 29580857 TI - Analytical interference of HBOC-201 (Hemopure, a synthetic hemoglobin-based oxygen carrier) on four common clinical chemistry platforms. AB - BACKGROUND: There are 13 million blood transfusions each year in the US. Limitations in the donor pool, storage capabilities, mass casualties, access in remote locations and reactivity of donors all limit the availability of transfusable blood products to patients. HBOC-201 (Hemopure(r)) is a second generation glutaraldehyde-polymer of bovine hemoglobin, which can serve as an "oxygen bridge" to maintain oxygen carrying capacity while transfusion products are unavailable. Hemopure presents the advantages of extended shelf life, ambient storage, and limited reactive potential, but its extracellular location can also cause significant interference in modern laboratory analyzers similar to severe hemolysis. METHODS: Observed error in 26 commonly measured analytes was determined on 4 different analytical platforms in plasma from a patient therapeutically transfused Hemopure as well as donor blood spiked with Hemopure at a level equivalent to the therapeutic loading dose (10% v/v). RESULTS: Significant negative error ratios >50% of the total allowable error (>0.5tAE) were reported in 23/104 assays (22.1%), positive bias of >0.5tAE in 26/104 assays (25.0%), and acceptable bias between -0.5tAE and 0.5tAE error ratio was reported in 44/104 (42.3%). Analysis failed in the presence of Hemopure in 11/104 (10.6%). Observed error is further subdivided by platform, wavelength, dilution and reaction method. CONCLUSION: Administration of Hemopure (or other hemoglobin based oxygen carriers) presents a challenge to laboratorians tasked with analyzing patient specimens. We provide laboratorians with a reference to evaluate patient samples, select optimal analytical platforms for specific analytes, and predict possible bias beyond the 4 analytical platforms included in this study. PMID- 29580858 TI - Analytical validation of an ultra low-cost mobile phone microplate reader for infectious disease testing. AB - Most mobile health (mHealth) diagnostic devices for laboratory tests only analyze one sample at a time, which is not suitable for large volume serology testing, especially in low-resource settings with shortage of health professionals. In this study, we developed an ultra-low-cost clinically-accurate mobile phone microplate reader (mReader), and clinically validated this optical device for 12 infectious disease tests. The mReader optically reads 96 samples on a microplate at one time. 771 de-identified patient samples were tested for 12 serology assays for bacterial/viral infections. The mReader and the clinical instrument blindly read and analyzed all tests in parallel. The analytical accuracy and the diagnostic performance of the mReader were evaluated across the clinical reportable categories by comparison with clinical laboratorial testing results. The mReader exhibited 97.59-99.90% analytical accuracy and <5% coefficient of variation (CV). The positive percent agreement (PPA) in all 12 tests achieved 100%, negative percent agreement (NPA) was higher than 83% except for one test (42.86%), and overall percent agreement (OPA) ranged 89.33-100%. We envision the mReader can benefit underserved areas/populations and low-resource settings in rural clinics/hospitals at a low cost (~$50 USD) with clinical-level analytical quality. It has the potential to improve health access, speed up healthcare delivery, and reduce health disparities and education disparities by providing access to a low-cost spectrophotometer.

PMID- 29580859 TI - Stage IV melanoma of unknown primary: A population-based study in the United States from 1973 to 2014. AB - BACKGROUND: Melanoma of unknown primary (MUP) is incompletely described on a population level. OBJECTIVE: We sought to characterize stage IV MUP in a population-based cancer registry. METHODS: We developed a novel search algorithm to identify cases of stage IV MUP in the Surveillance, Epidemiology, and End Results 18 registries from 1973 to 2014. Cases of stage IV melanoma of known primary (MKP) served as a comparison group. Age-standardized incidence rates, demographic characteristics, adjusted disease-specific survival, and Cox proportional hazard models were calculated for MUP and MKP. RESULTS: A total of 322 stage IV MUP cases and 12,796 stage IV MKP cases were identified in Surveillance, Epidemiology, and End Results 18 registries from 1973 to 2014. The incidence of stage IV MUP is increasing, particularly for patients younger than 30 years of age. In multivariate analyses, age older than 50 and a lack of surgical treatment were negative prognostic factors for stage IV MUP. Relative survival, but not 5-year adjusted disease-specific survival, was higher for stage IV MUP than for MKP. LIMITATIONS: Limitations include the retrospective study design and possible misclassification of MUP. CONCLUSIONS: The incidence of stage IV MUP is increasing, and stage IV MUP shares similar prognostic factors with stage IV MKP, including age and surgical treatment. PMID- 29580861 TI - Melanoma staging: Varying precision and terminal digit clustering in Breslow thickness data is evident in a population-based study. AB - BACKGROUND: Errors in Breslow thickness reporting can give misclassification of T category, an important classifier in melanoma staging. OBJECTIVE: We sought to investigate precision (number of digits) and terminal digit clustering in Breslow thickness and potential consequences for T category. METHODS: All first primary and morphologically verified invasive melanomas in Norway between 2008 and 2015 were included. A smoothing model was fitted to estimate the underlying Breslow thickness distribution without digit clustering. RESULTS: Thickness was reported for 13,057 (97.5%) patients; the median was 1.0 mm (range, 0.09-85). It was reported as whole numbers (15.6%), to 1 decimal (78.2%) and 2 decimal places (6.2%)-thin tumors with more precision than thick tumors. Terminal digit clustering was found with marked peaks in the observed frequency distribution for terminal digits 0 and 5, and with drops around these peaks. Terminal digit clustering increased proportions of patients classified with T1 and T4 tumors and decreased proportions classified with T2 and T3. LIMITATIONS: Breslow thickness was not reported in 2.5% of cases. CONCLUSIONS: The Norwegian recommendation of measurement to the nearest 0.1 mm was not followed. Terminal digit clustering was marked, with consequences for T category. Pathologists, clinicians, and epidemiologists should know that clustering of thickness data around T category cut points can impact melanoma staging with consequent effect on patient management and prognosis. PMID- 29580862 TI - Galactose metabolism and toxicity in Ustilago maydis. AB - In most organisms, galactose is metabolized via the Leloir pathway, which is conserved from bacteria to mammals. Utilization of galactose requires a close interplay of the metabolic enzymes, as misregulation or malfunction of individual components can lead to the accumulation of toxic intermediate compounds. For the phytopathogenic basidiomycete Ustilago maydis, galactose is toxic for wildtype strains, i.e. leads to growth repression despite the presence of favorable carbon sources as sucrose. The galactose sensitivity can be relieved by two independent modifications: (1) by disruption of Hxt1, which we identify as the major transporter for galactose, and (2) by a point mutation in the gene encoding the galactokinase Gal1, the first enzyme of the Leloir pathway. The mutation in gal1(Y67F) leads to reduced enzymatic activity of Gal1 and thus may limit the formation of putatively toxic galactose-1-phosphate. However, systematic deletions and double deletions of different genes involved in galactose metabolism point to a minor role of galactose-1-phosphate in galactose toxicity. Our results show that molecular triggers for galactose toxicity in U. maydis differ from yeast and mammals.

PMID- 29580864 TI - Epstein-barr virus DNAemia monitoring for the management of post-transplant lymphoproliferative disorder. AB - BACKGROUND: Post-transplant lymphoproliferative disorder (PTLD) is a potentially fatal complication of allogeneic hematopoietic cell transplantation (HCT). Epstein-Barr virus (EBV) reactivation (detectable DNAemia) predisposes to the development of PTLD. METHODS: We retrospectively studied 306 patients monitored for EBV DNAemia after Thymoglobulin-conditioned HCT to determine the utility of the monitoring in the management of PTLD. DNAemia was monitored weekly for >=12 weeks post-transplantation. RESULTS: Reactivation was detected in 82% of patients. PTLD occurred in 14% of the total patients (17% of patients with reactivation). PTLD was treated with rituximab only when and if the diagnosis was established. This allowed us to evaluate potential DNAemia thresholds for pre emptive therapy. We suggest 100,000-500,000 IU per mL whole blood as this would result in unnecessary rituximab administration to only 4-20% of patients and near zero mortality due to PTLD. After starting rituximab (for diagnosed PTLD), sustained regression of PTLD occurred in 25/25 (100%) patients in whom DNAemia became undetectable. PTLD progressed or relapsed in 12/17 (71%) patients in whom DNAemia was persistently detectable. DISCUSSION: In conclusion, for pre-emptive therapy of PTLD, we suggest threshold DNAemia of 100,000-500,000 IU/mL. Persistently detectable DNAemia after PTLD treatment with rituximab appears to have 71% positive predictive value and 100% negative predictive value for PTLD progression/relapse. PMID- 29580865 TI - Bone marrow-mesenchymal stromal cell infusion in patients with chronic kidney disease: A safety study with 18 months of follow-up. AB - BACKGROUND: Chronic kidney disease (CKD) is a progressive loss of kidney function and structure that affects approximately 13% of the population worldwide. A recent meta-analysis revealed that cell-based therapies improve impaired renal function and structure in preclinical models of CKD. We assessed the safety and tolerability of bone marrow-mesenchymal stromal cell (MSC) infusion in patients with CKD. METHODS: A single-arm study was carried out at one center with 18-month follow-up in seven eligible patients with CKD due to different etiologies such as hypertension, nephrotic syndrome (NS) and unknown etiology. We administered an intravenous infusion (1-2 * 106 cells/kg) of autologous cultured MSCs. The primary endpoint was safety, which was measured by number and severity of adverse events. The secondary endpoint was decrease in the rate of decrease in estimated glomerular filtration rate (eGFR). We compared kidney function during the follow up visits to baseline and 18 months prior to the intervention. RESULTS: Follow-up visits of all seven patients were completed; however, we have not observed any cell-related adverse events during the trial. Changes in eGFR (P = 0.10) and serum creatinine (P = 0.24) from 18 months before cell infusion to baseline in comparison with baseline to 18 months were not statistically significant. CONCLUSIONS: We showed safety and tolerability of a single-dose infusion of autologous MSCs in patients with CKD. PMID- 29580866 TI - Pyruvate dehydrogenase complex and lactate dehydrogenase are targets for therapy of acute liver failure. AB - BACKGROUND & AIMS: Acute liver failure is a rapidly progressive deterioration of hepatic function resulting in high mortality and morbidity. Metabolic enzymes can translocate to the nucleus to regulate histone acetylation and gene expression. METHODS: Levels and activities of pyruvate dehydrogenase complex (PDHC) and lactate dehydrogenase (LDH) were evaluated in nuclear fractions of livers of mice exposed to various hepatotoxins including CD95-antibody, alpha-amanitin, and acetaminophen. Whole-genome gene expression profiling by RNA-seq was performed in livers of mice with acute liver failure and analyzed by gene ontology enrichment analysis. Cell viability was evaluated in cell lines knocked-down for PDHA1 or LDH-A and in cells incubated with the LDH inhibitor galloflavin after treatment with CD95-antibody. We evaluated whether the histone acetyltransferase inhibitor garcinol or galloflavin could reduce liver damage in mice with acute liver failure. RESULTS: Levels and activities of PDHC and LDH were increased in nuclear fractions of livers of mice with acute liver failure. The increase of nuclear PDHC and LDH was associated with increased concentrations of acetyl-CoA and lactate in nuclear fractions, and histone H3 hyper-acetylation. Gene expression in livers of mice with acute liver failure suggested that increased histone H3 acetylation induces the expression of genes related to damage response. Reduced histone acetylation by the histone acetyltransferase inhibitor garcinol decreased liver damage and improved survival in mice with acute liver failure. Knock-down of PDHC or LDH improved viability in cells exposed to a pro-apoptotic stimulus. Treatment with the LDH inhibitor galloflavin that was also found to inhibit PDHC, reduced hepatic necrosis, apoptosis, and expression of pro-inflammatory cytokines in mice with acute liver failure. Mice treated with galloflavin also showed a dose-response increase in survival. CONCLUSION: PDHC and LDH translocate to the nucleus, leading to increased nuclear concentrations of acetyl-CoA and lactate. This results in histone H3 hyper-acetylation and expression of damage response genes. Inhibition of PDHC and LDH reduces liver damage and improves survival in mice with acute liver failure. Thus, PDHC and LDH are targets for therapy of acute liver failure. LAY SUMMARY: Acute liver failure is a rapidly progressive deterioration of liver function resulting in high mortality. In experimental mouse models of acute liver failure, we found that two metabolic enzymes, namely pyruvate dehydrogenase complex and lactic dehydrogenase, translocate to the nucleus resulting in detrimental gene expression. Treatment with an inhibitor of these two enzymes was found to reduce liver damage and to improve survival. PMID- 29580867 TI - Eosinophils Accelerate Pathogenesis of Psoriasis by Supporting an Inflammatory Milieu that Promotes Neutrophil Infiltration. AB - Eosinophils are proinflammatory granulocytes that are involved in the pathogenesis of various inflammatory reactions. However, their roles in psoriasis remain largely unknown. In this study, by examining the inflammatory features of the eosinophilic cell line EoL-1 and an imiquimod-induced murine model of psoriasis, we show that eosinophils provide inflammatory signals that accelerate the pathogenesis of psoriasis. EoL-1 cells constitutively expressed TLR7, which mediates acute and rapidly developing psoriatic inflammation. The activation of TLR7 on EoL-1 cells using R837 resulted in the secretion of inflammatory mediators that support the migration, activation, and survival of neutrophils. The underlying pathologic role of eosinophils in psoriatic inflammation was further substantiated by markedly decreased psoriasiform inflammation in imiquimod-treated DeltadblGATA mice, which have a systemic eosinophil deficiency. While imiquimod-treated wild-type mice showed a significant increase in the eosinophils in their skin, neutrophils remarkably outnumbered the eosinophils in the skin, lymph nodes, and spleen in wild-type mice after imiquimod application. In addition, lesional skin samples from psoriasis patients also showed up regulated eosinophil cytotoxic granules, accompanied by marked neutrophil infiltration. Based on these collective data, we propose that eosinophils accelerate psoriatic inflammation by supporting inflammatory microenvironments to favor the activation and infiltration of neutrophils. PMID- 29580868 TI - Downregulated TRPV1 Expression Contributes to Melanoma Growth via the Calcineurin ATF3-p53 Pathway. AB - Melanoma is the most lethal form of skin cancer with increasing incidence over the years. Because of its rapid proliferative and drastic metastatic capacity, the prognosis of melanoma remains dismal, although the targeted therapy and immunotherapy have gained revolutionary progress recently. Therefore, it is of necessity to further clarify the mechanism of melanoma pathogenesis for developing an alternative treatment strategy. Transient receptor potential vanilloid 1 (TRPV1) is a nonselective Ca2+ channel greatly involved in regulating cell apoptosis, proliferation, metabolism, and cancer development, but its role in melanoma remains unknown. Herein, we first found that TRPV1 expression was significantly decreased in melanoma tissues and cell lines, compared with nevus tissues and normal melanocytes, respectively. We then proved that TRPV1 overexpression or its agonist capsaicin treatment inhibited melanoma growth by activating p53 and inducing cell apoptosis. A subsequent mechanistic study revealed that TRPV1 induced Ca2+ influx to regulate p53 activation via calcineurin-ATF3 transcriptional cascade. Finally, the effect of TRPV1 on melanoma growth was proved in vivo. Altogether, our study demonstrates that TRPV1 is a potential tumor suppressor in melanoma.

PMID- 29580870 TI - Hyfraxins A and B, cytotoxic ergostane-type steroid and lanostane triterpenoid glycosides from the invasive ash dieback ascomycete Hymenoscyphus fraxineus. AB - A virulent culture of Hymenoscyphus fraxineus, the causal agent of ash dieback, was investigated for its production of secondary metabolites in a 70 L batch fermentation. Chemical analysis of the mycelial extract by means of flash chromatography and preparative HPLC led to the isolation of a new ergostane-type steroid (1) and a new related lanostane triterpenoid (2), both revealing the same glycosylation pattern. While their planar structures were elucidated by HR-ESIMS and NMR data, relative stereochemistry was assigned by ROESY correlations in conjunction with H,H and C,H coupling constants. Absolute configuration was determined based on ROESY correlations between the aglycons and the sugar moieties, which were identified in both cases as d-mannose by GC/MS analysis of the trimethylsilylated derivatives. The isolated compounds, for which we propose the trivial names hyfraxins A (1) and B (2), were found to be cytotoxic against the mouse fibroblast cell line L929 and exhibited moderate to weak activity against Gram-positive bacteria. PMID- 29580872 TI - Molecular and culture based assessment of bacterial pathogens in subjects with diabetic foot ulcer. AB - INTRODUCTION: Expeditious and precise discerning of bacterial pathogens is a fundamental grail, of clinical diagnostic microbiology. Genotypic detection is a budding substitute to recognize phenotypic culture based processes in bacterial identification. AIMS: We report a comparative evaluation of biochemical and genomic-based assays for exploring the commonest bacterial flora of infected diabetic foot ulcers along with clinical variables of subjects enrolled. METHODS: The pathogens selected (i) Staphylococcus aureus ii) Pseudomonas aeruginosa, iii) Escherichia coli and iv) Klebsiella pneumonia, stood for the most frequent isolates of diabetic foot infection in previous studies from Northern India. Identification of these pathogens were done by conventional assays and polymerase chain reaction. RESULTS: Of 50 specimens obtained from infected DFUs, 74% of cases were affirmative by bacteriological assays and 90% showed positivity via polymerase chain reaction (PCR). Among processed samples 44 isolates were detectable through phenotypic analysis and 65 bacteria by species-specific PCR. Thirteen samples and 21 isolates could not be scrutinized by phenotypic identification systems. The most prevalent pathogens identifiable were Klebsiella pneumonia, followed by Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. CONCLUSIONS: We have shown that PCR-based diagnostic methods improved the identification compared to conventional methods and highlight the incorporation of PCR due to shorten turnaround time translating into improved clinical outcomes. PMID- 29580871 TI - Effect of oral vitamin D supplementation on glycemic control in patients with type 2 diabetes mellitus with coexisting hypovitaminosis D: A parellel group placebo controlled randomized controlled pilot study. AB - CONTEXT: Vitamin D supplementation in type 2 diabetes mellitus patients may lead to improved glycemic control by improving insulin secretion and decreasing insulin resistance. AIMS: To investigate effect of oral vitamin D supplementation on glycemic control, in patients with type 2 diabetes mellitus and coexisting hypovitaminosis D. SETTINGS AND DESIGN: Randomized, Parallel Group, Placebo Controlled Trial carried out in a tertiary care hospital of Indian Armed Forces. METHODS AND MATERIAL: Sixty patients with coexisting type 2 diabetes mellitus and hypovitaminosis D were randomized into cases and controls and were supplemented with oral Vitamin D and microcrystalline cellulose respectively for six months. Subjects' HbA1c and vitamin D levels were monitored at the beginning and end of the study, fasting plasma glucose (FPG) & post prandial plasma glucose (PPPG) during monthly OPD visits. STATISTICAL ANALYSIS USED: Intra-group comparison was made by paired t test & unpaired t test was used for inter-group (A v/s B) comparisons. Repeated measures ANOVA was undertaken to compare values over time. RESULTS: The two groups were comparable for all parameters at baseline. Case group showed significant decrease in mean HbA1c levels (7.29% to 7.02%; P = 0.01), mean FPG levels (131.4 to 102.6 mg/dl; P = 0.04) and mean PPPG levels (196.2 to 135.0 mg/dl; P < 0.001). Incidentally, significant improvement in systolic as well as diastolic blood pressure and total cholesterol was also noted in the cases, while for LDL cholesterol improvement tended towards significance (p = 0.05). CONCLUSIONS: We found that oral vitamin D supplementation was associated with improved glycemic control and other metabolic parameters in patients with type 2 diabetes mellitus. Supplementation to achieve normal levels of vitamin D can be a promising adjuvant therapy for T2DM patients & coexisting hypovitaminosis D.

PMID- 29580874 TI - Comparison of the Dietary Antioxidant Profiles of 21 a priori Defined Mediterranean Diet Indexes. AB - BACKGROUND: The Mediterranean Diet (MD) is a dietary pattern that features a high quotient of antioxidant-rich foods. Differences in the level of dietary antioxidants intake reflected by different MD indexes has received little research attention. OBJECTIVE: The purpose of this study was to compare the dietary antioxidant profile of 21 a priori defined indexes of adherence to the MD. DESIGN: A cross-sectional study. PARTICIPANTS/SETTING: A total of 14,756 participants belonging to two Spanish European Prospective Investigation into Cancer and Nutrition cohorts, aged 32 to 69 years, recruited between 1992 and 1996, were included. MAIN OUTCOME MEASURE: Participants provided information on diet through a validated diet history questionnaire. Antioxidants (vitamin C, beta carotene and alpha-tocopherol), total antioxidant capacity, total polyphenols, flavonoids, and polyphenol antioxidant content score were estimated using different food composition databases. Twenty-one MD indexes were operationalized. STATISTICAL ANALYSIS: Spearman correlation coefficients between the indexes were calculated and hierarchical clustering was applied to identify cluster groups. Weighted kappa statistic was estimated to value the scoring agreements between indexes. Antioxidant profiles between the MD indexes were compared based on geometric mean intakes. The relationship between each MD index with the components of the antioxidant profile was evaluated using linear multivariable regression analysis. RESULTS: Correlation patterns between the MD indexes showed that about half of the indexes were moderately-to-weakly correlated with each other (rho<0.5). The main cluster groups derived denoted the high-, moderate-, and low-correlated MD indexes. Three MD indexes (MD pattern 2002, Prevention with MD, and Alternate MD index) presented the highest mean intakes of antioxidant vitamins, total antioxidant capacity, total polyphenols, flavonoids, and polyphenol antioxidant content score. These and other indexes (mainly those belonging to the MD Scale group) captured higher intake levels of dietary antioxidants overall. CONCLUSIONS: The level of dietary antioxidant intake that is captured through the different MD indexes differed due to the variation in their construction. Study results also suggest that some MD indexes reflect a higher antioxidant profile. PMID- 29580876 TI - Regulatory respiratory data refinement with reduced animal usage. AB - INTRODUCTION: Assessment of effects of potential drug candidates on the respiratory system is part of the regulatory preclinical safety assessment conducted prior to first in human trials (FTIH). Commonly, this is carried out utilizing head out plethysmography (HOP) or whole body plethysmography (WBP) which record only ventilatory parameters. When dosing via the inhaled route a more thorough respiratory assessment, including a direct measure of airway mechanics, is desirable. The aim of the present work was to improve the strategy for respiratory safety testing by a) evaluating a telemetered pleural pressure - HOP (PP-HOP) model and b) evaluating a crossover study design protocol in the WBP model to reduce variability and animal usage. METHODS: For the PP- HOP model, rats were surgically implanted with a telemetry device for measurement of pleural pressure. Animals were placed in HOP tubes and respiratory function assessed when exposed to methacholine at doses of 0 (saline only), 0.42, 1.6 and 3.8 mg/kg. WBP assessment was performed in rats in a crossover study design when treated with theophylline at doses of 0 (saline only), 3, 10 and 30 mg/kg. RESULTS: Data from the PP-HOP study confirmed the expected changes in ventilatory parameters and airway mechanics in response to inhaled methacholine, including an increase in pulmonary resistance and decrease in tidal volume. Data from the WBP crossover study demonstrated similar sensitivity and statistical power to detect changes in respiratory rate and tidal volume to a standard parallel group design. CONCLUSION: Measurement of PP-HOP in a stand-alone safety pharmacology study in conjunction with HOP assessment conducted as part of a toxicology study, represents an improved respiratory testing strategy for inhaled drugs. For compounds administered by other routes, we conclude that use of WBP using a crossover dosing design is a suitable alternative to parallel dosing groups, with a significant reduction in animal numbers and no loss of statistical power. PMID- 29580877 TI - Establishment of a novel microscale thermophoresis ligand-binding assay for characterization of SLC solute carriers using oligopeptide transporter PepT1 (SLC15 family) as a model system. AB - INTRODUCTION: Membrane proteins represent roughly one third of the human proteome and many of them serve as targets of therapeutic drugs. An exception is the SLC solute carrier superfamily with only a handful of approved drugs targeting SLCs. Indeed, for many of the SLCs, the natural transport substrates are still unknown. A major limitation for SLCs has been the difficulty to thoroughly characterize these multimembrane spanning proteins. The intrinsic properties of membrane proteins with alternative hydrophobic and hydrophilic domains lead to instability, making the purification tasks even more challenging compared to soluble proteins. This issue also holds true for conventional ligand-binding assays (LBAs) which usually require high-quality, pure and concentrated protein samples. Herein, we report a novel binding assay strategy to overcome these issues, taking advantage of a unique combination of yeast expression and microscale thermophoresis (MST). Following yeast overexpression of SLC15A1/PepT1 ortholog from moss Physcomitrella patens, PepTPp, which exhibits remarkable similarity to human PepT1, the approach was validated using dipeptide glycylsarcosine (Gly-Sar) and antiviral prodrug valacyclovir as test substrates. METHOD: The originality of our approach is based on the comparative analysis of solubilized total membrane preparations with or without expression of the SLC target of interest, using a yeast strain (S. cerevisiae), in which the corresponding endogenous SLC homolog is depleted. MST is a recently developed technique that takes advantage of the properties of biomolecules in solution to migrate along a temperature gradient. Importantly, this migration is affected by substrate binding. It is being monitored by fluorescence using labelled SLC molecules in the presence of different ligand concentrations. RESULTS: We herein report a novel MST/yeast-based method to characterize binding of ligands to SLCs without the need for a prior SLC-purification step. For validation purposes, we used a close eukaryotic homolog of the human H+-coupled oligopeptide transporter PepT1 (SLC15A1) that mediates uptake of di-tripeptides and peptide-like drugs as a test model. This approach allowed the successful confirmation of the binding of Gly-Sar at the mM range and revealed for the first time the KD of the antiviral prodrug valacyclovir to the PepT1 homolog at around 50 MUM. DISCUSSION: This novel LBA approach is independent of protein purification. It is suitable for drug discovery as it is upscalable to high throughput compound screening. It works well for SLC transporters which are underrepresented targets due to their difficulties to study them. Moreover, this approach could make a significant contribution toward "deorphanization" of SLCs, revealing their transport substrates. PMID- 29580878 TI - Multidisciplinary Conference and Clinical Management of Rectal Cancer. AB - BACKGROUND: Presentation of rectal cancer cases at a colorectal cancer multidisciplinary conference (CRC-MDC) is a required standard for the newly formed National Accreditation Program for Rectal Cancer administered by the Commission on Cancer. The aim of this study was to determine the frequency and manner in which CRC-MDC changed the management of rectal cancer patients at a tertiary academic center. STUDY DESIGN: All rectal cancer cases presented at a weekly CRC-MDC between July 2015 and June 2016 were prospectively included. Patient demographics and clinical information were recorded. The presenting physician completed a uniform written questionnaire outlining any changes in management as a result of the discussion. RESULTS: There were 408 rectal cancer cases included, and survey responses were obtained for 371 (91%). Thirty-nine patients (11%) had stage IV disease and 20 (5%) had locally recurrent cancer. There was a documented change in plan as a result of the CRC-MDC discussion in 97 of 371 (26%) cases surveyed. Changes in management included a change in therapy or change in therapy sequence in 76 cases, and recommendation of additional evaluation in 36 cases. Rates of management change were similar regardless of surgeon experience. Changes occurred in 23%, 28%, and 26% of cases presented by surgeons with <10, 10 to 20, and >20 years of experience, respectively (chi square p = 0.63). CONCLUSIONS: The CRC-MDC changes clinical management for a significant portion of rectal cancer patients at a tertiary center, independent of the presenting surgeon's years of clinical experience. Our results support the CRC-MDC standard for the National Accreditation Program for Rectal Cancer. PMID- 29580879 TI - Evaluating the Relevance of the 2013 Tokyo Guidelines for the Diagnosis and Management of Cholecystitis. AB - BACKGROUND: The 2013 Tokyo Guidelines (TG13) are used to diagnose, grade severity, and guide management of acute cholecystitis (AC). The aim of our study was to verify the diagnostic criteria, severity assessment, and management protocols based on the TG13. STUDY DESIGN: Our prospectively maintained emergency general surgery registry was used to review patients who had a surgical consultation for right upper quadrant pain (from 2013 to 2015). Diagnosis and severity were graded based on TG13 and compared with pathology reports. Our institutional management protocols were compared with TG13. RESULTS: Nine hundred and fifty-two patients were analyzed, of which 857 had biliary diseases. Mean age was 42 +/- 18 years and 67% were female. Seven hundred and seventy-nine had a cholecystectomy, 15 underwent cholecystostomy tube placement, and 63 patients were managed conservatively. Only 4% were febrile on presentation and 51% of patients had leukocytosis. Fifty-nine percent of patients did not have any signs of AC on ultrasonography. The TG13 criteria had a sensitivity of 53% for diagnosing AC (definitive 27%, suspected 26%, and undiagnosed 47%) when compared with the final pathology report; 92.5% of patients with grade I, 93% with grade II, and even 64% with grade III, underwent cholecystectomy safely at our institute. There were no differences in complication rates (3.7% vs 4.7%; p = 0.81), return to operating room rates (0.6% vs 0.7%; p = 0.95), or mortality rates (0.3% vs 0%; p = 0.96) between grade I and grade II patients who underwent early cholecystectomy. CONCLUSIONS: The TG13 diagnostic criteria lack sensitivity and missed more than half of the patients with AC, as many patients lack clinical signs (fever and leukocytosis). The TG13 recommendations for conservative management and delayed cholecystectomy in grade II and grade III disease are not warranted. PMID- 29580880 TI - What Are the Most Significant Cost and Value Drivers for Pancreatic Resection in an Integrated Healthcare System? AB - BACKGROUND: An initiative was established to improve value-based care for pancreatic surgery in a large nonprofit health system. Cost data were presented bimonthly to a hepatobiliary clinical performance group via videoconference. STUDY DESIGN: The direct costs were calculated for all patients undergoing distal pancreatectomy (DP) and pancreaticoduodenectomy (PD) between January 2014 and July 2017. Median length of stay, 30-day and 90-day mortality rates, readmission rate, and costs were stratified by surgeon volume using 2 published criteria: "volume pledge" criteria (>=5 PDs/year) and Leapfrog criteria (>=11 PDs/year). RESULTS: There were 270 DPs and 526 PDs performed in 14 hospitals spanning 4 states. Median PD costs were lower for high-volume surgeons (>=5 PDs/year), $21,026 vs $24,706 (p = 0.005). High-volume surgeons had a shorter length of stay (9 days vs 11 days; p < 0.001) for PD and DP (6 days vs 7 days; p = 0.001). Increased costs for low-volume surgeons included operative/anesthesia costs ($7,321 vs $6,325; p = 0.03), room and board ($5,828 vs $4,580; p = 0.01), and intensive care costs ($4,464 vs $3,113; p = 0.04). Operating time was increased for high-volume surgeons for DP and PD (p < 0.001). There was no difference in 30 day or 90-day mortality rates or readmissions for DP or PD when stratified by volume pledge criteria. There was no difference in total costs for DP or PD when stratified by Leapfrog criteria. CONCLUSIONS: There was a significant cost reduction for PD but not DP when the threshold of 5 PDs was used as a definition of high volume. The sharing of detailed financial data with HPB surgeons on a regular basis provides an opportunity to evaluate practice patterns and thereby reduce direct costs. PMID- 29580881 TI - Doping risk and career turning points in male elite road cycling (2005-2016). AB - OBJECTIVES: Determine whether career paths of elite male professional riders explain the risk of being sanctioned for an Anti-Doping Rules Violation through the International Cycling Union. DESIGN, METHODS: A discrete-time logit model explored the link between career path and ADRV risk in a database of 10,551 riders engaged in the first three world divisions (2005-2016), including 271 sanctioned riders. RESULTS: Despite a longer career (7.8years), sanctioned riders have a precarious path. The odds of finding a sanctioned rider within those who experienced a career interruption is 5.80 times higher than for a non-caught one. 61% of the caught riders have experienced a team change. The odds of finding a caught rider within those who experienced such a change is 1.35 times higher. 44% of caught riders start before 23years, vs 34% for non-sanctioned ones. The odds of being sanctioned are 1.69 times higher for doped riders beginning before 23. The odds of finding a sanctioned rider are 1.94 times higher among those starting their careers before 2005 (establishment of Pro Tour), than those who started in 2008 or after. In that year, the Cycling Anti-Doping Foundation and the biologic passport were both launched. CONCLUSIONS: Caught riders could have extended their more precarious careers with doping. The post-2005 generation effect could mean that riders are cleaner or slicker at hiding doping. The higher risk of being caught for riders starting after 23 might indicate that an early professional socialization reduces the risk by teaching them to be cleaner, or better at hiding doping. PMID- 29580882 TI - Astrocytes and neurons in locus coeruleus mediate restraint water immersion stress-induced gastric mucosal damage through the ERK1/2 signaling pathway. AB - Restraint water-immersion stress (RWIS) is considered to be a compound stress model that includes psychological and physical stimulation and may cause gastric mucosal damage. Studies have shown that locus coeruleus (LC) is involved in the gastrointestinal function, but whether it is involved in RWIS-induced gastric mucosal damage has not yet been reported. Here, we investigated the expression of glial fibrillary acidic protein (GFAP), c-Fos, and phosphorylation extracellular signal regulated kinase 1/2 (p-ERK1/2) in the LC after RWIS using immunocytochemical staining and western blotting in order to explore whether the ERK1/2 signaling pathway interacts with the neuron-astrocyte network in the LC during RWIS and whether it is involved in causing RWIS-induced gastric mucosal damage. Expression of c-Fos, GFAP, and p-ERK1/2 increased significantly following RWIS and peaked at 3 h after RWIS. After intracerebroventricular injection of c Fos antisense oligodeoxynucleotides (ASO) and astrocytic toxin L-a-aminoadipate (L-AA), the gastric mucosal damage and the activation of neurons and astrocytes in the LC significantly decreased. Intracerebroventricular injection of ERK1/2 signaling pathway inhibitor PD98059 suppressed gastric mucosal damage as well as the RWIS-induced activation of neurons and astrocytes in the LC. Activation of LC neurons and astrocytes induced by RWIS through the ERK1/2 signaling pathway may play a critical role in RWIS-induced gastric mucosa damage. PMID- 29580883 TI - Cre-expressing neurons in the cortical white matter of Ntsr1-Cre GN220 mice. AB - Genetically modified mouse strains that express Cre-recombinase in specific neuronal sub-populations have become widely used tools for investigating neuronal function. The Ntsr1-Cre GN220 mouse expresses this enzyme in corticothalamic neurons in layer 6 of cerebral cortex. We observed that about 7% of Cre expressing cells in the primary visual cortex are found within the white matter bordering layer 6. By using the immunohistochemical marker for layer 6 neurons, Forkhead box protein 2 (FoxP2), and fluorescently conjugated latex beads injected into the dorsal lateral geniculate nucleus, we show that about half of these cells are similar to and could belong to the layer 6 corticothalamic neuron population. The other half seems to be a distinct white matter (WM) neuron sub population that we estimate to constitute 2-4% of the total cortical Cre expressing population. Staining for the neuronal marker Neuronal nuclei (NeuN) revealed that about 15-40% of WM neurons are Cre-expressing. Thus, the potential contribution from WM neurons needs to be considered when interpreting the results from experiments using the Ntsr1-Cre GN220 mouse for investigating corticothalamic neuronal function. PMID- 29580884 TI - Mycobacterium tuberculosis. AB - In this infographic, the genetics, phylogeny, physiology, and pathogenesis mechanisms of Mycobacterium tuberculosis are shown. Mycobacterium tuberculosis is the etiological agent of tuberculosis (TB), the leading cause of death due to a single infectious agent, claiming 1.7 million lives in 2016. Of the deaths attributable to TB in 2016, 22% occurred in people coinfected with HIV, and close to 5% of the 10.4 million incident cases of this disease were resistant to at least two of the first-line TB drugs. In this infographic, we describe the fundamental features of the genetics, phylogeny, and physiology of this member of the phylum Actinobacteria, which is associated increasingly with drug resistance mediated by mutations and rearrangements in its single, circular chromosome. We also highlight the key pathogenesis mechanisms employed by this slow-growing, facultative intracellular bacterium, which include avoidance of host cell clearance by arrest of the normal macrophage maturation process. PMID- 29580886 TI - Physical Activity and Sarcopenia in the Geriatric Population: A Systematic Review. AB - INTRODUCTION: Sarcopenia is an aging-related health problem in the geriatric population. Sarcopenia reduces muscle mass, muscle strength, and physical performance. Although physical activity is protective against sarcopenia for older adults, there are limited studies in this area. The purpose of this study was to integrate and analyze research on physical activity and sarcopenia in the geriatric population. METHODS: Studies that assess sarcopenia were searched across electronic databases that included Medline, PubMed, CINAHL, and Cochrane Database of Systematic Reviews. Studies that implemented physical activity related intervention or research were included. A critical appraisal skills program was used for quality assessment of the selected articles. Study selection and data extraction were counted by 2 independent reviewers. RESULTS: Of the 149 references identified through the database search, 10 studies were included in this systematic review. Seven studies were randomized controlled trials, and 3 were cross-sectional or longitudinal. The results of 8 studies indicated significant improvement in muscle mass, muscle strength, and physical performance through exercise intervention, as determined by long-term observation. CONCLUSIONS: Physical activity is an effective protective strategy for sarcopenia. Most studies of older adults exercise intervention indicated that the participants achieved positive results, but maintenance of muscle strength appeared to depend on continuous implementation of certain types of physical activities. A limitation of these 10 reviewed studies was that there was no consistency in the measurement of sarcopenia. Therefore, sarcopenia measurement needs further investigation. PMID- 29580885 TI - Prophylaxis of Venous Thromboembolism in Geriatric Settings: A Cluster-Randomized Multicomponent Interventional Trial. AB - OBJECTIVES: To evaluate the efficacy of an intervention on the practice of venous thromboembolism prevention. DESIGN: A multicenter, prospective, controlled, cluster-randomized, multifaceted intervention trial consisting of educational lectures, posters, and pocket cards reminding physicians of the guidelines for thromboprophylaxis use. SETTINGS: Twelve geriatric departments with 1861 beds total, of which 202, 803, and 856 in acute care, post-acute care, and long-term care wards, respectively. PARTICIPANTS: Patients hospitalized between January 1 and May 31, 2015, in participating departments. MEASUREMENTS: The primary endpoint was the overall adequacy of thromboprophylaxis prescription at the patient level, defined as a composite endpoint consisting of indication, regimen, and duration of treatment. Geriatric departments were divided into an intervention group (6 departments) and control group (6 departments). The preintervention period was 1 month to provide baseline practice levels, the intervention period 2 months, and the postintervention period 1 month in acute care and post-acute care wards or 2 months in long-term care wards. Multivariable regression was used to analyze factors associated with the composite outcome. RESULTS: We included 2962 patients (1426 preintervention and 1536 postintervention), with median age 85 [79;90] years. For the overall 18.9% rate of inadequate thromboprophylaxis, 11.1% was attributable to underuse and 7.9% overuse. Intervention effects were more apparent in post-acute and long-term care wards although not significantly [odds ratio 1.44 (95% confidence interval 0.78;2.66), P = .241; and 1.44 (0.68, 3.06), P = .345]. Adequacy rates significantly improved in the postintervention period for the intervention group overall (from 78.9% to 83.4%; P = .027) and in post-acute care (from 75.4% to 86.3%; P = .004) and long-term care (from 87.0% to 91.7%; P = .050) wards, with no significant trend observed in the control group. CONCLUSIONS/IMPLICATIONS: This study failed to demonstrate improvement in prophylaxis adequacy with our intervention. However, the intervention seemed to improve practices in post-acute and long-term care but not acute care wards. PMID- 29580887 TI - Neuroimaging correlates of narcolepsy with cataplexy: A systematic review. AB - Recent developments in neuroimaging techniques have advanced our understanding of biological mechanisms underpinning narcolepsy. We used MEDLINE to retrieve neuroimaging studies to compare patients with narcolepsy and healthy controls. Thirty-seven studies were identified and demonstrated several replicated abnormalities: (1) gray matter reductions in superior frontal, superior and inferior temporal, and middle occipital gyri, hypothalamus, amygdala, insula, hippocampus, cingulate cortex, thalamus, and nucleus accumbens, (2) decreased fractional anisotropy in white matter of fronto-orbital and cingulate area, (3) reduced brain metabolism or cerebral blood flow in middle and superior frontal, and cingulate cortex (4) increased activity in inferior frontal gyri, insula, amygdala, and nucleus accumbens, and (5) N-acetylaspartate/creatine phosphocreatine level reduction in hypothalamus. In conclusion, all the replicated findings are still controversial due to the limitations such as heterogeneity or size of the samples and lack of multimodal imaging or follow-up. Thus, future neuroimaging studies should employ multimodal imaging methods in a large sample size of patients with narcolepsy and consider age, duration of disease, age at onset, severity, human leukocyte antigen type, cerebrospinal fluid hypocretin levels, and medication intake in order to elucidate possible neuroimaging characteristic of narcolepsy and identify therapeutic targets. PMID- 29580888 TI - Characterization of mouse chorda tympani responses evoked by stimulation of anterior or posterior fungiform taste papillae. AB - Different gustatory papilla types vary in their locations on the tongue. Distinctions have often made between types, but variation within fungiform papillae has seldom been explored. Here, regional differences in fungiform papillae were investigated by flowing solutions selectively over either an anterior fungiform (AF, tongue tip) or a posterior fungiform (PF, middle third) region as taste-evoked activity was measured in the chorda tympani nerve of C57BL/6J (B6) mice. Significantly larger responses were evoked by NaCl applied to the AF than PF region, and the ENaC blocker amiloride reduced the NaCl response size only for the former. Umami synergy, based on co-presenting MSG and IMP, was larger for the AF than PF region. The regions did not differ in response size to sour chemicals, but responses to l-lysine, l-arginine, sucrose, and tetrasodium pyrophosphate were larger for the AF than PF region. Thus, fungiform papillae on the tongue tip differed from those found further back in their transduction mechanisms for salty and umami compounds. Gustatory sensitivity also showed regional variation, albeit with a complex relationship to palatability and taste quality. Overall, the data support a regional organization for the mouse tongue, with different functional zones for the anterior, middle, and posterior thirds. PMID- 29580889 TI - Behavioral evaluation of auditory stream segregation in rats. AB - Perceptual organization of sound sequences into separate sound sources or streams is called auditory stream segregation. Neural substrates for this process in both the spectral and temporal domains remain to be elucidated. Despite abundant knowledge about their auditory physiology, behavioral evidence for auditory streaming in rodents is still limited. We provided behavioral evidence for auditory streaming in the go/no-go discrimination task, but not in the two alternative choice task. In the go/no-go discrimination phase, rats were able to discriminate different rhythms corresponding to segregated or integrated tone sequences in both short inter-tone interval (ITI) and long ITI conditions. Nevertheless, performance was poorer in the long ITI group. In probe testing, which assessed the ability to discriminate one of the segregated tone sequences from ABA- tone sequences, the detection rate increased with the difference in frequency (DeltaF) for short (100 ms), but not long (200 ms) ITIs. Our results indicate that auditory streaming in rats on both the spectral and temporal features in the ABA- tone paradigm is qualitatively analogous to that observed in human psychophysics studies. This suggests that rodents are a valuable model for investigating the neural substrates of auditory streaming. PMID- 29580890 TI - Mifepristone attenuates depression-like changes induced by chronic central administration of interleukin-1beta in rats. AB - Increased proinflammatory cytokines, such as interleukin (IL)-1beta, may play an important role in the etiology of depression because they cause the hypothalamic pituitary-adrenal axis to release glucocorticoids (GC) and induce dysfunction of serotonin and norepinephrine neurotransmission. Sustained increase in GC may activate microglia to induce neuroinflammation, and suppress astrocytes to produce neurotrophins, which lead to neuronal apoptosis. Here, we tested the hypothesis that glucocorticoid receptor (GR) antagonist mifepristone (RU486) may attenuate IL-1beta-induced depression-like behavior by regulating the neuroinflammation and neurotrophin functions of microglia and astrocytes. Rats received intracerebroventricular injections of IL-1beta (10 ng) and/or subcutaneous injections of RU486 for 14 days. Then animal depression-like behaviors, serum corticosterone concentration, the levels of pro-inflammatory cytokines (TNF-alpha, IL-6), mRNA and protein expressions of CD11b, GFAP and neurotrophins (pro-BDNF, BDNF, GDNF and their receptors TrkB, p75, GFRalpha-1 and GFRalpha-2) in the amygdala were studied. Compared to controls, significantly decreased rearing score and increased defecation in the open field test, decreases in ratio of open/closed time in the elevated plus maze and in sucrose preference, while increased level of corticosterone in the serum were found in the rats administrated with IL-1beta. IL-1beta administration also reduced the expressions of GFAP, BDNF, GDNF and its receptor GFR-alpha1, but increased the expressions of CD11b, pro-BDNF, p75 and pro-inflammatory cytokines (TNF-alpha, IL 6) concentrations. RU486 treatment markedly attenuated these changes induced by IL-1beta, except for the expressions of GFR-alpha1. In conclusion, RU486 may improve depression-like changes by suppressing microglia and inflammation and promoting astrocytes to restore neurotrophin function. PMID- 29580891 TI - Repeated social stress leads to contrasting patterns of structural plasticity in the amygdala and hippocampus. AB - Previous studies have demonstrated that repeated immobilization and restraint stress cause contrasting patterns of dendritic reorganization as well as alterations in spine density in amygdalar and hippocampal neurons. Whether social and ethologically relevant stressors can induce similar patterns of morphological plasticity remains largely unexplored. Hence, we assessed the effects of repeated social defeat stress on neuronal morphology in basolateral amygdala (BLA), hippocampal CA1 and infralimbic medial prefrontal cortex (mPFC). Male Wistar rats experienced social defeat stress on 5 consecutive days during confrontation in the resident-intruder paradigm with larger and aggressive Wild-type Groningen rats. This resulted in clear social avoidance behavior one day after the last confrontation. To assess the morphological consequences of repeated social defeat, 2 weeks after the last defeat, animals were sacrificed and brains were stained using a Golgi-Cox procedure. Morphometric analyses revealed that, compared to controls, defeated Wistar rats showed apical dendritic decrease in spine density on CA1 but not BLA. Sholl analysis demonstrated a significant dendritic atrophy of CA1 basal dendrites in defeated animals. In contrast, basal dendrites of BLA pyramidal neurons exhibited enhanced dendritic arborization in defeated animals. Social stress failed to induce lasting structural changes in mPFC neurons. Our findings demonstrate for the first time that social defeat stress elicits divergent patterns of structural plasticity in the hippocampus versus amygdala, similar to what has previously been reported with repeated physical stressors. Therefore, brain region specific variations may be a universal feature of stress-induced plasticity that is shared by both physical and social stressors. PMID- 29580893 TI - D-Cycloserine Facilitates Reversal in an Animal Model of Post-traumatic Stress Disorder. AB - Many psychiatric disorders are associated with cognitive dysfunction that is ineffectively treated by existing pharmacotherapies and which may contribute to poor real-world functioning. D-cycloserine (DCS) is a partial N-methyl-D aspartate (NMDA) agonist that has attracted attention because of its cognitive enhancing properties, including in people with post-traumatic stress disorder (PTSD). Here, we examined the effect of DCS on reversal learning - a type of cognitive flexibility - following exposure to single prolonged stress (SPS), a rodent model of PTSD. Male Sprague Dawley rats (n = 64) were trained to press levers in an operant chamber, matched for performance and assigned to SPS or control (unstressed) groups. Following SPS, rats received three additional lever press sessions, followed by a side bias test on day three. One day later they learned a response discrimination rule (press left or right lever, opposite to side bias) and on a subsequent day were trained (and tested) for reversal to the opposite lever. DCS (15 mg/kg) or vehicle was administered 30 minutes prior to the reversal session. No between-group differences were found in acquisition or retrieval of the initial rule, but a significant drug x stress interaction on response discrimination reversal indicated that DCS had a greater beneficial effect on SPS rats' cognitive flexibility than it did on performance in controls. These findings add to a growing literature on the beneficial effects of DCS for treating a wide variety of deficits that develop following exposure to extreme stress and may have implications for the development of novel pharmacotherapies for PTSD. PMID- 29580892 TI - Cocaine- and amphetamine-regulated transcript peptide (CART) induced reward behavior is mediated via Gi/o dependent phosphorylation of PKA/ERK/CREB pathway. AB - Although the role of cocaine- and amphetamine-regulated transcript peptide (CART) in modulating the mesolimbic reward pathway has been suggested, underlying cellular mechanisms have not been elucidated. Herein, we investigate the involvement of Gi/o dependent protein kinase A (PKA)/extracellular signal regulated kinase (ERK)/cAMP response element binding protein (CREB) signaling in CART induced reward behavior. The rat was implanted with a stimulating electrode targeted at the lateral hypothalamus (LH)-medial forebrain bundle (MFB) and conditioned to intracranial self-stimulation (ICSS) in an operant chamber. Intracerebroventricular (icv) administration of CART (55-102) dose-dependently lowered ICSS threshold suggesting reward promoting action, however, pretreatment with subeffective doses of Gi/o inhibitor (pertussis toxin, PTX) or PKA inhibitor (Rp-cAMPS) or ERK inhibitor (U0126) via icv route, attenuated CART mediated reward experience. Operant conditioned rats showed increased pCREB levels in the nucleus accumbens shell (AcbSh), ventral tegmental area (VTA) and hypothalamic paraventricular nucleus (PVN). Infusion of CART (icv) in the conditioned rats augmented the population of pCREB positive cells in the AcbSh, VTA and PVN areas, but not in the arcuate nucleus (ARC). Pretreatment with U0126 significantly decreased CART induced pCREB activation in the AcbSh and VTA, but not in PVN and ARC. ICSS or CART induced CREB mRNA expression in Acb and VTA was attenuated by U0126. We suggest that recruitment of Gi/o dependent PKA/ERK/CREB phosphorylation signaling in Acb and VTA might play an important role in CART induced reward behavior. PMID- 29580894 TI - Gut microbiota profiles in treatment-naive children with attention deficit hyperactivity disorder. AB - BACKGROUNDS: Although increasing evidence suggests a role for the gut microbiota in neurodevelopment, the actual structure and composition of microbiota in children with attention-deficit/hyperactivity disorder (ADHD) remain unclear. METHODS: Thus, the present study aimed to define the characteristics of gut microbiota in treatment-naive children with ADHD and to assess their relationship with the severity of ADHD symptoms. High-throughput pyrosequencing was used to investigate the microbiota composition in fecal matter from 51 children with ADHD and 32 healthy controls (HC). RESULTS: An operational taxonomical unit (OTU) level analysis revealed a significant decrease in the fractional representation of Faecalibacterium in children with ADHD compared to HC. In individuals with ADHD, the abundance of Faecalibacterium was negatively associated with parental reports of ADHD symptoms. However, there was no significant difference in alpha diversity between the ADHD and control groups. CONCLUSIONS: This present findings support the involvement of microbiota alteration in psychiatric diseases and Faecalibacterium may represent a potential novel marker of gut microbiota in ADHD. Future studies are needed to validate these findings and to elucidate the temporal and causal relationships between these variables. PMID- 29580895 TI - Effect of mobile laminar airflow units on airborne bacterial contamination during neurosurgical procedures. AB - BACKGROUND: Surgical site infections (SSIs) after neurosurgery are potentially life-threatening and entail great costs. SSIs may occur from airborne bacteria in the operating room, and ultraclean air is desired during infection-prone cleaning procedures. Door openings and the number of persons present in the operating room affect the air quality. Mobile laminar airflow (MLAF) units, with horizontal laminar airflow, have previously been shown to reduce airborne bacterial contamination. AIM: To assess the effect of MLAF units on airborne bacterial contamination during neurosurgical procedures. METHODS: In a quasi-experimental design, bacteria-carrying particles (colony-forming units: cfu) during neurosurgical procedures were measured with active air-sampling in operating rooms with conventional turbulent ventilation, and with additional MLAF units. The MLAF units were shifted between operating rooms monthly. Colony-forming unit count and bacterial species detection were conducted after incubation. Data was collected for a period of 18 months. FINDINGS: A total of 233 samples were collected during 45 neurosurgical procedures. The use of MLAF units significantly reduced the numbers of cfu in the surgical site area (P < 0.001) and above the instrument table (P < 0.001). Logistic regression showed that the only significant predictor affecting cfu count was the use of MLAF units (odds ratio: 41.6; 95% confidence interval: 11.3-152.8; P < 0.001). The most frequently detected bacteria were coagulase-negative staphylococci. CONCLUSION: MLAF successfully reduces cfu during neurosurgery to ultraclean air levels. MLAF units are valuable when the main operating room ventilation system is unable to produce ultraclean air in infection-prone clean neurosurgery. PMID- 29580896 TI - p53 and glucose metabolism: an orchestra to be directed in cancer therapy. AB - Metabolic reprogramming is a hallmark of cancer with a strong impact on tumor cell survival, proliferation, dissemination, and resistance to therapy. As such, it has represented a promising therapeutic target for cancer. Although cancer cells may exhibit a wide range of metabolic profiles, the enhancement of aerobic glycolysis to generate lactate and ATP (Warburg effect) is a cancer-associated trait, which is under regulation of both oncogenes and tumor suppressor genes. Particularly, the tumor suppressor protein p53 was shown to revert the Warburg effect, and to negatively influence the oncogenic metabolic adaption of cancer cells. This review provides a systematization of the p53 influence on glycolysis and oxidative phosphorylation (OXPHOS), giving attention to the interplay of p53 with key signaling pathways, including c-Myc, HIF-1, LKB1/AMPK, and PI3K/Akt, as well as to mutant p53 gain-of-function. It also contributes to a better understanding of distinct metabolic profiles in heterogeneous tumor cell populations, and of its impact on cancer therapeutic resistance. Additionally, a reflection on current strategies adopted in clinical trials to overcome therapeutic resistance is presented, highlighting the main limitations and future therapeutic perspectives based on metabolic reprogramming. In particular, this review emphasizes the p53 activation as a promising therapeutic strategy to reprogram tumor glucose metabolism, conducting to cell death. Moreover, potential synergisms between p53-activating agents and metabolic inhibitors are discussed, fostering the improvement of cancer therapy. PMID- 29580898 TI - Deep sequencing-based characterization of transcriptome of Pyrus ussuriensis in response to cold stress. AB - Pyrus ussuriensis is extremely cold hardy when fully acclimated, but knowledge relevant to the molecular mechanisms underlying this economically valuable trait is still limited so far. In this study, global transcriptome profiles of Pyrus ussuriensis under cold conditions (4 degrees C) over a time course were generated by high-throughput sequencing. In total, >57,121,199 high quality clean reads were obtained with approximately 11.0 M raw data for each library. Among them, the values of 66.84%-72.03% of clean reads in the digital transcript abundance measurement could be well mapped to the pear genome database, resulting in the identification of 8544 differentially expressed genes (DEGs) having 43 Gene Ontology (GO) terms and 17 clusters of orthologous groups (COG) involved in 385 Kyoto Encyclopedia of Genes and Genomes (KEGG) defined pathways. These comprised 3124 (1033 up-regulated, 2091 down-regulated), 1243 (729 up-regulated, 514 down-regulated), and 750 (458 up-regulated, 292 down-regulated) genes from the cold-treated samples at 5, 12 and 24 h, respectively. The accuracy of the RNA Seq derived transcript expression data was validated by analyzing the expression patterns of 16 DGEs by quantitative real-time PCR. Plant-pathogen interaction, plant hormone signal transduction, Photosynthesis, signal transduction, innate immune response and response to biotic stimulus were the most significantly enriched GO categories among in the DEGs. A total of 335 transcription factors were shown to be cold responsive. In addition, a number of genes involved in the catabolism and signaling of hormones were significantly affected by the cold stress. The RNA-Seq and digital expression profiling provides valuable insights into the understanding the molecular events related to cold responses in Pyrus ussuriensis and dataset may help guide future identification and functional analysis of potential genes that are important for enhancing cold hardiness. PMID- 29580897 TI - Prevalence and risk factors of Giardia duodenalis in domestic rabbbits (Oryctolagus cuniculus) in Jilin and Liaoning province, northeastern China. AB - BACKGROUND: Giardia duodenalis is one of the most important intestinal parasites that can infect virtually all animals, including rabbits and humans. However, there is little information regarding the prevalence and genotypes of G. duodenalis in domestic rabbits in China. METHODS: A total of 426 rabbit fecal samples (136 from Shenyang City, 174 from Changchun City, and 116 from Jilin City) were examined by Lugol's iodine staining with microscopy analysis, and the positive samples were genotyped at the triosephosphate isomerase (tpi) and the beta giardin (bg) gene loci using nested PCR. RESULTS: Forty-two (9.86%) out of 426 rabbit fecal samples were G. duodenalis-positive under microscopy analysis, and the highest G. duodenalis infection rate was 23.08% on farm 6. The prevalence of G. duodenalis in rabbits from different cities ranged from 1.47% to 14.37%. Among different age groups, G. duodenalis prevalence in rabbits ranged from 5.41% to 12.58%. The prevalence of G. duodenalis in outdoor rabbits and indoor rabbits was 14.29% and 6.77%, respectively. In the present study, region and farming mode were highly correlated with G. duodenalis infection in rabbits. All 42 G. duodenalis isolates were successfully amplified and sequenced at the tpi and bg loci, and only G. duodenalis assemblage B were identified. CONCLUSION: This study not only further confirmed the dominance of G. duodenalis assemblage B in rabbits, but also further improved the foundation data concerning the distribution of G. duodenalis assemblages in China.

AB - Spinal cord injury (SCI) is a serious devastating condition and it has a high mortality rate and morbidity rate. The early pathological changes in the immediate phase of SCI may play a major part in the development of secondary injury. Alterations in the expression of many long noncoding RNAs (lncRNAs) have been shown to play fundamental roles in the diseases of the central nervous system. However, the roles of lncRNAs and messenger RNAs (mRNAs) in the immediate phase of SCI are not clear. We examined the expression of mRNAs and lncRNAs in a rat model at 2 h after SCI and identified the differentially expressed lncRNAs (DE lncRNAs) and differentially expressed mRNAs (DE mRNAs) using microarray analysis. 772 DE lncRNAs and 992 DE mRNAs were identified in spinal cord samples in the immediate phase following SCI compared with control samples. Moreover, Gene Ontology (GO) term annotation results showed that CXCR chemokine receptor binding, neutrophil apoptotic process, neutrophil migration, neutrophil extravasation, macrophage differentiation, monocyte chemotaxis and cellular response to interleukin-1 (IL-1) were the main significantly enriched GO terms. The results of Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that the DEGs were enriched in toll-like receptor signaling pathway, p53 signaling pathway, MAPK signaling pathway and Jak-STAT signaling pathway. IL6, MBOAT4, FOS, TNF, JUN, STAT3, CSF2, MYC, CCL2 and FGF2 were the top 10 high degree hub nodes and may be important targets in the immediate phase of SCI. The current study on provides novel insights into how lncRNAs and mRNAs regulate the pathogenesis of the immediate phase after SCI.

AB - Amyotrophic lateral sclerosis (ALS) causes rapidly progressive paralysis and death within 5 years from diagnosis due to degeneration of the motor circuits. However, a significant population of ALS patients also shows cognitive impairments and progressive hippocampal pathology. Likewise, the mutant SOD1(G93A) mouse model of ALS (mSOD1), in addition to loss of spinal motor neurons, displays altered spatial behavior and hippocampal abnormalities including loss of parvalbumin-positive interneurons (PVi) and enhanced long-term potentiation (LTP). However, the cellular and molecular mechanisms underlying these morpho-functional features are not well understood. Since removal of TrkB.T1, a receptor isoform of the brain-derived neurotrophic factor, can partially rescue the phenotype of the mSOD1 mice, here we tested whether removal of TrkB.T1 can normalize the number of PVi and the LTP in this model. Stereological analysis of hippocampal PVi in control, TrkB.T1-/-, mSOD1, and mSOD1 mice deficient for TrkB.T1 (mSOD1/T1-/-) showed that deletion of TrkB.T1 restored the number of PVi to physiological level in the mSOD1 hippocampus. The rescue of PVi neuron number is paralleled by a normalization of high-frequency stimulation-induced LTP in the pre-symptomatic mSOD1/T1-/- mice. Our experiments identified TrkB.T1 as a cellular player involved in the homeostasis of parvalbumin expressing interneurons and, in the context of murine ALS, show that TrkB.T1 is involved in the mechanism underlying structural and functional hippocampal degeneration. These findings have potential implications for hippocampal degeneration and cognitive impairments reported in ALS patients at early stages of the disease. PMID- 29580902 TI - Early life trauma: An exploratory study of effects on OXTR and NR3C1 gene expression and nurturing self-efficacy in mothers of infants. AB - BACKGROUND: In animals, adverse early experience alters oxytocinergic and glucocorticoid activity and maternal behavior in adulthood. This preliminary study explored associations among childhood trauma (loss of a parent or sexual abuse in childhood), maternal self-efficacy, and leukocyte gene expression (mRNA) of oxytocin and glucocorticoid receptors (OXTR and NR3C1) in mothers of infants. METHODS: 62 mothers (20 with early life trauma) with healthy 3-month old infants reported maternal self-efficacy, depression, infant temperament, and overall social support; the effects of early trauma on these measures were assessed. Of these, 35 mothers (14 with early trauma) underwent blood draws after 2 infant feeding times; their OXTR and NR3C1 mRNA was compared to a control group of 25 no infant women without early trauma, and also was examined for associations with self-efficacy. RESULTS: OXTR mRNA was increased in mothers of infants versus no infant controls (p < 0.0003), and mothers with greatest prior maternal experience had higher OXTR than those with less experience (0-2 vs. 3+ older children, p < 0.033). Mothers with early trauma and less maternal experience had lower OXTR mRNA than no-trauma mothers (p < 0.029) and lower NR3C1 mRNA than controls (p < 0.004). Mothers with depression also had lower NR3C1 than other mothers (p < 0.003) but did not differ in OXTR. Mothers with early trauma also reported their support network to be less helpful and more upsetting and unpredictable than other mothers (p < 0.035-p < 0.005). Regarding maternal behavior, in mothers with early trauma, helpful support networks increased self-reported nurturing self efficacy when babies were not fussy but decreased it with fussy babies (p < 0.05). Support was unrelated to self-efficacy in no-trauma mothers. Similarly, among mothers with low OXTR or NR3C1 (-1SD, most having early trauma and lower maternal experience), greater support was associated with lower self-efficacy (p < 0.05), while mothers with high OXTR or NR3C1 (+1SD) tended to have higher self efficacy with greater support. CONCLUSIONS: These preliminary findings need confirmation in a larger sample but suggest that childhood trauma influences maternal behavior and both OXTR and NR3C1 pathways in mothers of infants, and that both depression and prior maternal experience may be other important factors. Effects on maternal behavior appear to require more complex modeling. PMID- 29580903 TI - Neuromagnetic correlates of audiovisual word processing in the developing brain. AB - The brain undergoes enormous changes during childhood. Little is known about how the brain develops to serve word processing. The objective of the present study was to investigate the maturational changes of word processing in children and adolescents using magnetoencephalography (MEG). Responses to a word processing task were investigated in sixty healthy participants. Each participant was presented with simultaneous visual and auditory word pairs in "match" and "mismatch" conditions. The patterns of neuromagnetic activation from MEG recordings were analyzed at both sensor and source levels. Topography and source imaging revealed that word processing transitioned from bilateral connections to unilateral connections as age increased from 6 to 17 years old. Correlation analyses of language networks revealed that the path length of word processing networks negatively correlated with age (r = -0.833, p < 0.0001), while the connection strength (r = 0.541, p < 0.01) and the clustering coefficient (r = 0.705, p < 0.001) of word processing networks were positively correlated with age. In addition, males had more visual connections, whereas females had more auditory connections. The correlations between gender and path length, gender and connection strength, and gender and clustering coefficient demonstrated a developmental trend without reaching statistical significance. The results indicate that the developmental trajectory of word processing is gender specific. Since the neuromagnetic signatures of these gender-specific paths to adult word processing were determined using non-invasive, objective, and quantitative methods, the results may play a key role in understanding language impairments in pediatric patients in the future. PMID- 29580901 TI - Species-conserved SYNGAP1 phenotypes associated with neurodevelopmental disorders. AB - SYNGAP1 loss-of-function variants are causally associated with intellectual disability, severe epilepsy, autism spectrum disorder and schizophrenia. While there are hundreds of genetic risk factors for neurodevelopmental disorders (NDDs), this gene is somewhat unique because of the frequency and penetrance of loss-of-function variants found in patients combined with the range of brain disorders associated with SYNGAP1 pathogenicity. These clinical findings indicate that SYNGAP1 regulates fundamental neurodevelopmental processes that are necessary for brain development. Here, we describe four phenotypic domains that are controlled by Syngap1 expression across vertebrate species. Two domains, the maturation of cognitive functions and maintenance of excitatory-inhibitory balance, are defined exclusively through a review of the current literature. Two additional domains are defined by integrating the current literature with new data indicating that SYNGAP1/Syngap1 regulates innate survival behaviors and brain structure. These four phenotypic domains are commonly disrupted in NDDs, suggesting that a deeper understanding of developmental Syngap1 functions will be generalizable to other NDDs of known or unknown etiology. Therefore, we discuss the known molecular and cellular functions of Syngap1 and consider how these functions may contribute to the emergence of disease-relevant phenotypes. Finally, we identify major unexplored areas of Syngap1 neurobiology and discuss how a deeper understanding of this gene may uncover general principles of NDD pathobiology. PMID- 29580904 TI - Different profiles of decision making and physiology under varying levels of stress in trained military personnel. AB - Decision making is one of the most vital processes we use every day, ranging from mundane decisions about what to eat to life-threatening choices such as how to avoid a car collision. Thus, the context in which our decisions are made is critical, and our physiology enables adaptive responses that account for how environmental stress influences our performance. The relationship between stress and decision making can additionally be affected by one's expertise in making decisions in high-threat environments, where experts can develop an adaptive response that mitigates the negative impacts of stress. In the present study, 26 male military personnel made friend/foe discriminations in an environment where we manipulated the level of stress. In the high-stress condition, participants received a shock when they incorrectly shot a friend or missed shooting a foe; in the low-stress condition, participants received a vibration for an incorrect decision. We characterized performance using signal detection theory to investigate whether a participant changed their decision criterion to avoid making an error. Results showed that under high-stress, participants made more false alarms, mistaking friends as foes, and this co-occurred with increased high frequency heart rate variability. Finally, we examined the relationship between decision making and physiology, and found that participants exhibited adaptive behavioral and physiological profiles under different stress levels. We interpret this adaptive profile as a marker of an expert's ingrained training that does not require top down control, suggesting a way that expert training in high-stress environments helps to buffer negative impacts of stress on performance. PMID- 29580905 TI - [Management of epilepsia in older]. AB - Epilepsy increases in frequency with age, above 60, with consequences in terms of independence. Stroke and dementia are the most frequent etiologies. Clinical diagnostic of epileptic seizure is challenging at this age, and a clinical algorithm is proposed. Sleep EEG during one hour seems to be the most useful exam. Interictal and critical discharges can be seen during sleep in dementia ; relation between hyperexcitability and evolution of cognition has to be precised in this pathology. In a therapeutical point of view, it is necessary to bear in mind the pharmacological consequences of aging, polytherapies, and the frequency of adverse events in this age group. Two molecules, lamotrigine and levetiracetam are recommended as first line treatment. Pronostic is good, as the majority of patients are seizure-free in monotherapy. PMID- 29580906 TI - Post-traumatic psychiatric disorders: PTSD is not the only diagnosis. AB - Traumatic events and their consequences are often hidden or minimised by patients for reasons linked to the post-traumatic stress disorder itself (inexpressibility, shame, depressive thoughts, fear of stigmatisation, etc.). Although post-traumatic stress disorder (PTSD) remains the most widely known disorder, chronic post-traumatic psychiatric disorders are many and varied. After a trauma, the practitioner has to check for the different clinical forms of post traumatic psychological consequences: PTSD is not the only diagnosis. Based on our own clinical experience compared to the international literature, we think necessary to build a didactic classification describing chronic post-traumatic symptoms and syndromes. Post traumatic depressions and bereavement lead to high risk of suicidal crisis and self-harm behaviours. Re-experiencing are felt with anxiety, hyper arousal increases anxious reactivity, and avoidance strategies increase anticipatory anxiety, indicating post-traumatic anxiety disorders (agoraphobia, specific phobia, obsessive compulsive disorder, separation anxiety, social phobia). Characterising an often-severe clinical picture, the co occurrence of post-traumatic and chronic psychotic symptoms is not unusual (post traumatic schizophrenia, post-traumatic depression with mood-congruent psychotic features, non-schizophrenic post-traumatic psychotic disorder, and bipolar reaction to trauma). A physical injury occurring at the same time as a traumatic exposure increases the risk of developing post-traumatic stress disorder later which, in turn, afflicts the subjective perception of the physical health (development of somatoform and psychosomatic disorders, comorbidity with a post concussion syndrome). The trauma may cause a rupture in the biography of a person, also in his/her internal physiological functioning as in his/her social activities (impacts of instinctive functions and behaviours, personality changes, and adjustment difficulties on professional and personal life). Although a nomenclature is necessary for semiological descriptions, a thorough analysis of the patient's general psychological functioning must also be conducted.

PMID- 29580908 TI - [Extracorporeal life support and heart-lung transplant in children]. AB - Extracorporeal life support and heart and/or lung transplant are the last resort in children with end-stage cardiac and/or pulmonary failure and short-term life threaten. Currently, circulatory support is used as a bridge to recovery or as a bridge to transplant but not as a destination therapy. The Excor Berlin Heart is the long-lasting external pneumatic ventricular assist system that is currently available from infancy to adulthood. Long-term prognosis after pediatric cardiac and/or pulmonary transplant is conditioned by the occurrence of graft failure, coronary disease of the cardiac graft, viral infections and bronchiolitis obliterans of the pulmonary graft, the incidence of which increase with time. The scarcity of grafts and the risk of acute rejection due to lack of compliance with immunosuppressive treatment require the transplant specialized teams to choose the best candidates according to psychosocial and biological criteria. The next expected developments concern mainly long-term ventricular assistance with systems that allow for greater autonomy and a return to the child's home.

AB - Alcohol interacts with numerous neurotransmission systems and particularly glutamatergic NMDA receptors and gabaergic GABAA receptors. Binge drinking induces both cerebral damages and cognitive deficits. Alcohol addiction is associated with an increase in the activation threshold of dopaminegic neurons and with a negative emotional state. Alcohol addiction is associated with a deficit in inhibitory control and an increase in motivation to drink alcohol. Environemental cues associated with alcohol trigger drinking desire and can induce relapse. Alcohol disturbs synaptic plasticity phenomena within the brain reward system.

AB - TAK-448 is a kisspeptin analog with improved in vivo potency. In our previous studies in the rat JDCaP prostate cancer model, TAK-448 showed more rapid and profound reductions in plasma testosterone (T) and prostate-specific antigen (PSA, a biomarker of prostate tumor growth) levels than the gonadotropin releasing hormone (GnRH) analog leuprolide (TAP-144); however, its effects on tumor volume and subsequent tumor recurrence have not been elucidated fully. To overcome these challenges, we established the rat VCaP subcutaneous xenograft model replicating both the androgen-sensitive and castration-resistant phases of prostate cancer, and we performed pharmacokinetic/efficacy (PK/E) correlation analyses to compare the overall anti-tumor growth effects of TAK-448 to those of TAP-144. Our approach demonstrated TAK-448 had greater anti-tumor growth potential, including in the castration-resistant phase, than TAP-144 in this rat VCaP model. TAK-448 treatment was associated with a reduction in intra-tumoral dihydrotestosterone levels, which might explain its superior anti-tumor activity. Thus, our PK/E analysis was effective at providing new insights into the therapeutic efficacy of TAK-448 as a novel ADT agent in our rat VCaP model.

AB - STUDY OBJECTIVE: According to the American Academy of Pediatrics, pediatricians are to counsel and provide long-acting reversible contraceptives (LARCs) as first line of defense contraceptives because they are the most effective. We wanted to explore positive influences on LARC placement for pediatricians, particularly compared with providers in other specialties who care for women. DESIGN: Survey methods with data analyzed using analyses of variance and general linear models in statistical software SPSS version 24.0 (IBM Corp). SETTING: Online survey. PARTICIPANTS: Participants were 224 providers across the state of Ohio who specialize in family medicine (51.8%), obstetrics/gynecology (17.9%), pediatrics (16.5%), and internal medicine (13.8%). Most of the sample was female (50.9%) and Caucasian (74.6%). The most frequent provider types were Doctors of Osteopathic Medicine (42.0%), followed by Doctors of Medicine (37.9%), and Certified Nurse Practitioners (8.5%). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Attitudes about LARCs, perceived norms about placing LARCs, perceived behavioral control over placing LARCs, intentions to place LARCs. RESULTS: Means for all of the variables (attitudes, perceived norms, perceived behavioral control, and intentions to place) differed according to provider specialty. A pattern emerged across these variables in which internal medicine and pediatric practitioners reported lower attitudes, perceived norms, perceived behavioral control, and intentions to place LARCs than family medicine and obstetrics/gynecology practitioners, in that order. CONCLUSION: To increase positive attitudes and perceived norms about LARCs, professional organizations should increase communication to providers about the importance and expectations to place, counsel about, and facilitate placement of LARCs, and medical schooling can improve LARC counseling and procedural training to medical students, interns, and residents. Because perceived behavioral control is linked to intentions to place LARCs, perhaps providers would feel more confident to place them if they had more deliberate training. For pediatricians in particular, perhaps encouraging those who do not currently provide LARC methods to begin with training in implant placement would be a way to capitalize on their more favorable attitudes about implants. For pediatricians who do not feel comfortable providing device placement themselves, other strategies should be encouraged to facilitate provision of LARCs. PMID- 29580917 TI - Comparison of Parental and Adolescent Views on the Confidential Interview and Adolescent Health Risk Behaviors within the Gynecologic Setting. AB - STUDY OBJECTIVE: To explore parental and adolescent views on the confidential interview in the gynecologic setting and compare adolescent reported risk-taking behaviors with parental perception. DESIGN: Anonymous surveys were administered separately to parents/guardians and adolescents between the ages of 11 and 17 years. Information pertaining to the patient's Tanner stage and reason for visit was obtained from the provider. This first phase served as the usual care group. In the second phase of the study, surveys were again distributed after a brief educational intervention. Linear regression analysis, Wilcoxon rank sum test, and Fisher exact test were used where appropriate. SETTING AND PARTICIPANTS: Pediatric and adolescent gynecology clinics in 2 tertiary hospitals. INTERVENTIONS: Brief educational handout on key concepts of the confidential interview. MAIN OUTCOME MEASURES: Parental perception of the confidential interview and adolescent risk-taking behaviors. RESULTS: A total of 248 surveys were included in the final analysis, which accounts for 62 adolescent and parent/guardian pairs in each group. Most parents and adolescents reported perceived benefit to the confidential interview. However, parents were less likely to rate benefits of private time specifically for their own adolescent and less than half of the parents believed that adolescents should have access to private time in the gynecologic setting. Parents/guardians as well as adolescents feared that the confidential interview would limit the parent's ability to take part in decision-making. The low support for confidential time for their adolescent was not different in the usual care group compared with the intervention group, although there was a trend toward parental acceptance with increased adolescent age. Adolescents were consistently more likely to report more risk-taking behaviors than their parents perceived. CONCLUSION: There is a discord between parental perception and adolescent reports of risk-taking behaviors. This is coupled with a lack of understanding or comfort regarding the benefits of the confidential interview among parents and adolescents who present for gynecologic care. A short educational intervention had only a modest effect on parental perceptions regarding the confidential interview. PMID- 29580918 TI - PGC-1alpha sparks the fire of neuroprotection against neurodegenerative disorders. AB - Recently, growing evidence has demonstrated that peroxisome proliferator activated receptor gamma (PPARgamma) coactivator-1alpha (PGC-1alpha) is a superior transcriptional regulator that acts via controlling the expression of anti-oxidant enzymes and uncoupling proteins and inducing mitochondrial biogenesis, which plays a beneficial part in the central nervous system (CNS). Given the significance of PGC-1alpha, we summarize the current literature on the molecular mechanisms and roles of PGC-1alpha in the CNS. Thus, in this review, we first briefly introduce the basic characteristics regarding PGC-1alpha. We then depict some of its important cerebral functions and discuss upstream modulators, partners, and downstream effectors of the PGC-1alpha signaling pathway. Finally, we highlight recent progress in research on the involvement of PGC-1alpha in certain major neurodegenerative disorders (NDDs), including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. Collectively, the data presented here may be useful for supporting the future potential of PGC-1alpha as a therapeutic target. PMID- 29580919 TI - Sirtuins in mitochondrial stress: Indispensable helpers behind the scenes. AB - Mitochondria play an essential part in guaranteeing normal cellular physiological functions through providing ATP and participating in diverse processes and signaling pathways. Recently, more and more studies have revealed the vital roles of mitochondria in coping with stressors in the aging process, metabolic disturbances and neurological disorders. Mitochondrial stress responses, including the mitochondrial unfolded protein response (UPRmt), antioxidant defense, mitochondrial fission, mitochondrial fusion and mitophagy, are induced to maintain cellular integrity in response to stress. The sirtuin family, a group of NAD+-dependent deacetylases, has been the focus of much attention in recent years for their multiple regulatory functions, especially in aging and metabolism. Recent reports validated the significant link between mitochondrial stress responses and the sirtuin family, which may help to elucidate the pathogenesis and therapies for diseases such as Alzheimer's disease or Parkinson's disease. This review will summarize recent related studies and illuminate the interplay between sirtuins and mitochondrial stress. PMID- 29580920 TI - Beyond ROS clearance: Peroxiredoxins in stress signaling and aging. AB - Antioxidants were long predicted to have lifespan-promoting effects, but in general this prediction has not been well supported. While some antioxidants do seem to have a clear effect on longevity, this may not be primarily as a result of their role in the removal of reactive oxygen species, but rather mediated by other mechanisms such as the modulation of intracellular signaling. In this review we discuss peroxiredoxins, a class of proteinaceous antioxidants with redox signaling and chaperone functions, and their involvement in regulating longevity and stress resistance. Peroxiredoxins have a clear role in the regulation of lifespan and survival of many model organisms, including the mouse, Caenorhabditis elegans and Drosophila melanogaster. Recent research on peroxiredoxins - in these models and beyond - has revealed surprising new insights regarding the interplay between peroxiredoxins and longevity signaling, which will be discussed here in detail. As redox signaling is emerging as a potentially important player in the regulation of longevity and aging, increased knowledge of these fascinating antioxidants and their mode(s) of action is paramount. PMID- 29580921 TI - Potential role for Ext1-dependent heparan sulfate in regulating P311 gene expression in A549 carcinoma cells. AB - BACKGROUND: Exostosin-1 (EXT1), a member of the EXT protein family, is indispensable for synthesis of heparan sulfate (HS) chains that bind to and modulate the signaling efficiency of numerous growth factor activities. We have previously shown that Ext1 mutated mouse embryonic fibroblasts produce short sulfated HS chains which dramatically influence tumor cell behavior in a 3 dimensional (3D) heterospheroid system composed of tumor cells and fibroblasts. METHODS: In this study, we have used both 2D co-culture and 3D heterospheroid models, consisting of human A549 carcinoma cells co-cultured with wild-type or Ext1-mutated mouse embryonic fibroblasts. RESULTS AND CONCLUSIONS: Gene expression profiling of differentially expressed genes in fibroblast/A549 heterospheroids identified P311 as a gene substantially down-regulated in A549 cells co-cultured with Ext1-mutated fibroblasts. In addition, we observed that the Ext1 mutants displayed reduced Tgf-beta1 mRNA levels and lower levels of secreted active TGF-beta protein. Re-introduction of Ext1 in the Ext1 mutant fibroblasts rescued the levels of Tgf-beta1 mRNA, increased the amounts of secreted active TGF-beta in these cells, as well as P311 mRNA levels in adjacent A549 cells. Accordingly, small interfering RNAs (siRNAs) against fibroblast Tgf beta1 reduced P311 expression in neighboring A549 tumor cells. Our data raises the possibility that fibroblast Ext1 levels play a role in P311 expression in A549/fibroblast co-culture through TGF-beta1. GENERAL SIGNIFICANCE: This study considers a possible novel mechanism of Ext1-regulated heparan sulfate structure in modifying tumor-stroma interactions through altering stromal tgf-beta1 expression. PMID- 29580922 TI - Characteristic glycopeptides associated with extreme human longevity identified through plasma glycoproteomics. AB - BACKGROUND: Glycosylation is highly susceptible to changes of the physiological conditions, and accordingly, is a potential biomarker associated with several diseases and/or longevity. Semi-supercentenarians (SSCs; older than 105 years) are thought to be a model of human longevity. Thus, we performed glycoproteomics using plasma samples of SSCs, and identified proteins and conjugated N-glycans that are characteristic of extreme human longevity. METHODS: Plasma proteins from Japanese semi-supercentenarians (SSCs, 106-109 years), aged controls (70-88 years), and young controls (20-38 years) were analysed by using lectin microarrays and liquid chromatography/mass spectrometry (LC/MS). Peak area ratios of glycopeptides to corresponding normalising peptides were subjected to orthogonal projections to latent structures discriminant analysis (OPLS-DA). Furthermore, plasma levels of clinical biomarkers were measured. RESULTS: We found two lectins such as Phaseolus vulgaris, and Erythrina cristagalli (ECA), of which protein binding were characteristically increased in SSCs. Peak area ratios of ECA-enriched glycopeptides were successfully discriminated between SSCs and controls using OPLS-DA, and indicated that tri-antennary and sialylated N-glycans of haptoglobin at Asn207 and Asn211 sites were characterized in SSCs. Sialylated glycans of haptoglobin are a potential biomarker of several diseases, such as hepatocellular carcinoma, liver cirrhosis, and IgA-nephritis. However, the SSCs analysed here did not suffer from these diseases. CONCLUSIONS: Tri-antennary and sialylated N-glycans on haptoglobin at the Asn207 and Asn211 sites were abundant in SSCs and characteristic of extreme human longevity. GENERAL SIGNIFICANCE: We found abundant glycans in SSCs, which may be associated with human longevity. PMID- 29580924 TI - Electrical-biological hybrid system for CO2 reduction. AB - Here we have developed an electrochemical-biological hybrid system to fix CO2. Natural biological CO2 fixation processes are relatively slow. To increase the speed of fixation we applied electrocatalysts to reduce CO2 to formate. We chose a user-friendly organism, Escherichia coli, as host. Overall, the newly constructed CO2 and formate fixation pathway converts two formate and one CO2 to one pyruvate via glycine and L-serine in E. coli. First, one formate and one CO2 are converted to one glycine. Second, L-serine is produced from one glycine and one formate. Lastly, L-serine is converted to pyruvate. E. coli's genetic tractability allowed us to balance various parameters of the pathway. The carbon flux of the pathway was sufficient to compensate L-serine auxotrophy in the strain. In total, we integrated both electrocatalysis and biological systems into a single pot to support E. coli growth with CO2 and electricity. Results show promise for using this hybrid system for chemical production from CO2 and electricity. PMID- 29580923 TI - Endoglin pathway genetic variation in preeclampsia: A validation study in Norwegian and Latina cohorts. AB - OBJECTIVE: The purpose of this study was to validate our previous genetic association findings related to the endoglin (ENG) pathway from an American Caucasian preeclampsia cohort in independent preeclampsia cohorts. We also sought to explore the ENG pathway for new genetic associations in these independent cohorts. STUDY DESIGN: We used a tagging single nucleotide (tSNP) approach to assess genetic variability across five ENG pathway genes (ENG, TGFbeta1, TGFbetaR1, ALK1, and TGFbetaR2) in a Caucasian cohort from Norway (n = 77 preeclampsia cases & n = 63 normotensive controls) and a White Hispanic cohort from Southern California (n = 69 preeclampsia cases & n = 106 normotensive controls). MAIN OUTCOME MEASURES: Univariate analyses (Chi Square, Fisher's Exact) and multivariate logistic regression were conducted to evaluate the association between tSNP genotype distributions and pregnancy outcome in each cohort. Logistic regression models were adjusted for maternal age at delivery, infant sex, parity, smoking during pregnancy, and pre-pregnancy BMI. RESULTS: Although we were unable to replicate our previous SNP-specific findings (ENG rs11792480, rs10121110; TGFbetaR2 rs6550005; p's > 0.05), we found that genetic variation in TGFbetaR1[ALK5] (rs6478974) and TGFbetaR2 (rs11129420, rs6802220, rs1155708, rs3773640, rs3773663) was significantly associated with preeclampsia in the Norwegian cohort and genetic variation in ALK1 (rs706819) and TGFbetaR2 (rs9843942) was significantly associated with preeclampsia in the Latina cohort. CONCLUSION: Overall, our results provide further support for the involvement and investigation of the endoglin pathway in preeclampsia. PMID- 29580926 TI - 19q13.12 microdeletion syndrome fibroblasts display abnormal storage of cholesterol and sphingolipids in the endo-lysosomal system. AB - Microdeletions in 19q12q13.12 cause a rare and complex haploinsufficiency syndrome characterized by intellectual deficiency, developmental delays, and neurological movement disorders. Variability in the size and interval of the deletions makes it difficult to attribute the complex clinical phenotype of this syndrome to an underlying gene(s). As an alternate approach, we examined the biochemical and metabolic features of fibroblasts from an affected individual to derive clues as to the molecular basis for the syndrome. Immunofluorescence and electron microscopy of affected fibroblasts revealed an abnormal endo-lysosomal compartment that was characterized by rapid accumulation of lysosomotropic dyes, elevated LAMP1 and LAMP2 expression and vacuoles containing membrane whorls, common features of lysosomal lipid storage disorders. The late endosomes lysosomes (LE/LY) of affected fibroblasts accumulated low-density lipoprotein cholesterol, and displayed reduced cholesterol esterification and increased de novo cholesterol synthesis, indicative of defective cholesterol transport to the endoplasmic reticulum. Affected fibroblasts also had increased ceramide and sphingolipid mass, altered glycosphingolipid species and accumulation of a fluorescent lactosylceramide probe in LE/LY. Autophagosomes also accumulated in affected fibroblasts because of decreased fusion with autolysosomes, a defect associated with other lysosomal storage diseases. Attempts to correct the cholesterol/sphingolipid storage defect in fibroblasts with cyclodextrin, sphingolipid synthesis inhibitors or by altering ion transport were unsuccessful. Our data show that 19q13.12 deletion fibroblasts have abnormal accumulation of cholesterol and sphingolipids in the endo-lysosomal system that compromises organelle function and could be an underlying cause of the clinical features of the syndrome.

AB - CRISPR/Cas9 or Cpf1-introduced double strand break dramatically decreases bacterial cell survival rate, which hampers multiplex genome editing in bacteria. In addition, the requirement of a foreign DNA template for each target locus is labor demanding and may encounter more GMO related regulatory hurdle in industrial applications. Herein, we developed a multiplex automated Corynebacterium glutamicum base editing method (MACBETH) using CRISPR/Cas9 and activation-induced cytidine deaminase (AID), without foreign DNA templates, achieving single-, double-, and triple-locus editing with efficiencies up to 100%, 87.2% and 23.3%, respectively. In addition, MACBETH was applied to generate a combinatorial gene inactivation library for improving glutamate production, and pyk&ldhA double inactivation strain was found to improve glutamate production by 3-fold. Finally, MACBETH was automated with an integrated robotic system, which would enable us to generate thousands of rationally engineered strains per month for metabolic engineering of C. glutamicum. As a proof of concept demonstration, the automation platform was used to construct an arrayed genome-scale gene inactivation library of 94 transcription factors with 100% success rate. Therefore, MACBETH would be a powerful tool for multiplex and automated bacterial genome editing in future studies and industrial applications.

AB - OBJECTIVES: The aim of this study is to elucidate the possible mechanism of neurotoxic effect of acrylamide (AA) applied during pregnancy on fetal brain development and to show the effect of N-acetylcysteine (NAC) on AA toxicity. MATERIALS AND METHODS: Four groups were formed with 9 pregnant rats each as control (C), acrylamide (AA), N-acetylcysteine (NAC), acrylamide plus N acetylcysteine (AA plus NAC) groups. Caesarian section was implemented on the 20th day of pregnancy. Malondialdehyde (MDA), reduced glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and Brain-derived neurotrophic factor (BDNF) levels were analyzed and histopathologic examinations were performed in brain tissues of the fetuses. RESULTS: Our data indicated that AA caused necrotic death and hemorrhagic damages in fetal brain tissue with decreasing BNDF levels and increasing oxidative stress. N acetylcysteine prevented the toxic effects of its on fetal brain (p < 0.05). CONCLUSION: Our study indicated that acrylamide has toxic effects in the fetal brain and N-acetylcysteine prevents its toxic effect.

AB - Yarrowia lipolytica, a nonpathogenic, nonconventional, aerobic and dimorphic yeast, is considered an oleaginous microorganism due to its excellent ability to accumulate large amounts of lipids. Glucose-6-phosphate dehydrogenase (G6PD) is one of two key enzymes involved in the lipid accumulation in this fungi, which catalyzes the oxidative dehydrogenation of glucose-6-phosphate to 6 phosphoglucono-delta-lactone with the reduction of NADP+ to NADPH. In this study, the full-length gene of G6PD from Y. lipolytica (YlG6PD) was cloned without intron and heterogeneously expressed in E. coli. Then, YlG6PD was purified and biochemically characterized in details. Kinetic analysis showed that YlG6PD was completely dependent on NADP+ and its apparent Km for NADP+ was 33.3 MUM. The optimal pH was 8.5 and the maximum activity was around 47.5 degrees C. Heat inactivation profiles revealed that it remained 50% of maximal activity after incubation at 48 degrees C for 20 min YlG6PD activity was competitively inhibited by NADPH with a Ki value of 56.04 MUM. Most of the metal ions have no effect on activity, but Zn2+ was a strong inhibitor. Furthermore, the determinants in the coenzyme specificity of YlG6PD were investigated. Kinetic analysis showed that the single mutant R52D completely lost the ability to utilize NADP+ as its coenzyme, suggesting that Arg-52 plays a decisive role in NADP+ binding in YlG6PD. The identification of Y. lipolytica G6PD may provide useful scientific information for metabolic engineering of this yeast as a model for bio-oil production.

PMID- 29580931 TI - Pseudomonas aeruginosa sequence type 357 with VEB extended-spectrum beta lactamases in the UK: relatedness and resistance. PMID- 29580930 TI - Which non-carbapenem antibiotics are active against extended-spectrum beta lactamase-producing Enterobacteriaceae? AB - In this study, the activity of 18 non-carbapenem antibiotics was evaluated against 100 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBL-Ec) and 50 ESBL-producing Klebsiella pneumoniae (ESBL-Kp) isolated from urinary tract infections and bacteraemia in 2016. Minimum inhibitory concentrations (MICs) were determined using reference methods and the susceptibility profiles were defined according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) 2017 recommendations. All of the ESBL-Ec isolates were susceptible to ceftazidime/avibactam and a great majority of them were susceptible to fosfomycin (98%), piperacillin/tazobactam (97%), amikacin (97%) and nitrofurantoin (96%). Mecillinam, cefoxitin and ceftolozane/tazobactam remained active against 92%, 83% and 78% of the ESBL-Ec isolates, respectively. Moreover, 100%, 94% and 90% of the ESBL-Kp tested were susceptible to ceftazidime/avibactam, amikacin and mecillinam, respectively. This study showed that there are non-carbapenem options (including orally administrable drugs) for the treatment of all of the situations of ESBL-Ec or ESBL-Kp infections, with ceftazidime/avibactam being the most efficient alternative. PMID- 29580932 TI - Postradiation hypothyroidism in head and neck cancers: A Department of Veterans Affairs single-institution case-control dosimetry study. AB - We performed a case-control study to characterize the dose-volume relationship and other variables leading to hypothyroidism after head and neck (H&N) cancer radiation therapy (RT) in a homogenous Veterans Affairs (VA) population. All records of patients receiving RT for various H&N cancers at a single VA medical center between 2007 and 2013 (n = 143) were screened for post-RT thyroid stimulating hormone (TSH) levels (n = 77). The thyroid gland was contoured on each slice of the planning computed tomography scan when available (hypothyroid: n = 18; euthyroid > 2 years: n = 16), and dose-volume histograms based on physical dose and biologically equivalent dose (BED) were compared systematically to find the significant dose-volume thresholds that distinguish the patients who developed clinical hypothyroidism. Dosimetric and clinical variables were considered in univariate and multivariate analysis. Preirradiation prevalence of hypothyroidism was 8 of 143 (5.6%). After RT, 36 of 77 (47%) screened patients had abnormally high TSH, of which 22 of 36 (61%) had clinical hypothyroidism after 1.29 +/- 0.99 years. The median follow-up durations were 3.3 years and 4.7 years for euthyroid and hypothyroid patients, respectively. Compared with the euthyroid cohort (n = 41), these hypothyroid patients displayed no significant difference in age, gender, primary tumor site, thyroid volume, hypertension, diabetes, or use of chemotherapy, surgery, or intensity-modulated radiation therapy (IMRT). They were more likely to have had stage 3 or 4 cancer than euthyroid patients (86.5% vs 73.2%, p = 0.01). The odds ratios of hypothyroidism for stage 3 + 4 cancers and V50Gy < 75% were 5.0 and 0.2, respectively (p < 0.05). Equivalent BED threshold of V75Gy3 < 75% gave an odds ratio of 0.156 for developing hypothyroidism (p = 0.02). The prevalence of post-RT clinical hypothyroidism was relatively high for patients with H&N cancers and warrants routine surveillance, especially in those with higher stage malignancy. V50Gy < 75% may be a useful guideline to avoid hypothyroidism. We also show BED data which could be used for unconventionally fractionated schemes, and V75Gy3 < 75% may be a useful guideline. PMID- 29580933 TI - 3D treatment planning system-Pinnacle system. AB - The treatment planning system is key for the success of external beam radiotherapy, directly impacting the quality of treatment plans and accuracy of dose calculation in the plans. In this article, we provided an overview of the Pinnacle treatment planning system for external beam planning, including 3 dimensional (3D) conformal plans, step-shoot intensity modulated radiotherapy (IMRT) plans, and volumetric modulated arc therapy (VMAT) plans. We discussed dose calculation algorithm and other utilities, including image fusion, plan documentation, and adaptive planning. Based on our many years of clinical experience with the system, the aim of this article is to provide readers with a summary of this particular planning system. PMID- 29580934 TI - 3D treatment planning on helical tomotherapy delivery system. AB - The helical tomotherapy is a technologically advanced radiation dose delivery system designed to perform intensity-modulated radiation therapy (IMRT). It is mechanistically unique, based on a small 6-MV linear accelerator mounted on a ring gantry that rotates around the patient while the patient moves through a bore, ultimately yielding a helical path of radiation dose delivery. The helical pattern of dose delivery differentiated tomotherapy from other contemporary radiation therapy systems at the time of its inception. The accompanying 3 dimensional (3D) treatment planning system has been developed to solely support this specific type of dose delivery system. The treatment planning system has 2 modules identified as TomoHelical and TomoDirect to perform IMRT and conformal radiation therapy, respectively. The focus of this work within the scope of this special issue on 3D treatment planning systems is to assess the use of planning tools to generate treatment plans for helical tomotherapy. Clinical examples are used throughout to demonstrate the quality and differences of various clinical scenarios planned with tomotherapy. PMID- 29580935 TI - Seasonal Patterns of Community Participation and Mobility of Wheelchair Users Over an Entire Year. AB - OBJECTIVE: To describe how people who use wheelchairs participate and move at home and in the community over an entire yearlong period, including during times of inclement weather conditions. DESIGN: Longitudinal mixed-methods research study. SETTING: Urban community in Canada. PARTICIPANTS: People who use a wheelchair for home and community mobility (N=11). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Use of a global positioning system (GPS) tracker for movement in community (number of trips per day), use of accelerometer for bouts of wheeling mobility (number of bouts per day, speed, distance, and duration), prompted recall interviews to identify supports and barriers to mobility and participation. RESULTS: More trips per day were taken during the summer (P= .03) and on days with no snow and temperatures above 0 degrees C. Participants reliant on public transportation demonstrated more weather-specific changes in their trip patterns. The number of daily bouts of mobility remained similar across seasons; total daily distance wheeled, duration, and speed were higher on summer days, days with no snow, and days with temperatures above 0 degrees C. A higher proportion of outdoor wheeling bouts occurred in summer (P=.02) and with temperatures above 0 degrees C (P=.03). Inaccessible public environments were the primary barrier to community mobility and participation; access to social supports and private transportation were the primary supports. CONCLUSIONS: Objective support is provided for the influence of various seasonal weather conditions on community mobility and participation for people who use a wheelchair. Longitudinal data collection provided a detailed understanding of the patterns of, and influences on, wheelchair mobility and participation within wheelchair users' own homes and communities. PMID- 29580936 TI - Safety and Feasibility of a Neuroscience Critical Care Program to Mobilize Patients With Primary Intracerebral Hemorrhage. AB - OBJECTIVE: To measure the impact of a progressive mobility program on patients admitted to a neurocritical critical care unit (NCCU) with intracerebral hemorrhage (ICH). The early mobilization of critically ill patients with spontaneous ICH is a challenge owing to the potential for neurologic deterioration and hemodynamic lability in the acute phase of injury. Patients admitted to the intensive care unit have been excluded from randomized trials of early mobilization after stroke. DESIGN: An interdisciplinary working group developed a formalized NCCU Mobility Algorithm that allocates patients to incremental passive or active mobilization pathways on the basis of level of consciousness and motor function. In a quasi-experimental consecutive group comparison, patients with ICH admitted to the NCCU were analyzed in two 6-month epochs, before and after rollout of the algorithm. Mobilization and safety endpoints were compared between epochs. SETTING: NCCU in an urban, academic hospital. PARTICIPANTS: Adult patients admitted to the NCCU with primary intracerebral hemorrhage. INTERVENTION: Progressive mobilization after stroke using a formalized mobility algorithm. MAIN OUTCOME MEASURES: Time to first mobilization. RESULTS: The 2 groups of patients with ICH (pre-algorithm rolllout, n=28; post-algorithm rollout, n=29) were similar on baseline characteristics. Patients in the postintervention group were significantly more likely to undergo mobilization within the first 7 days after admission (odds ratio 8.7, 95% confidence interval 2.1, 36.6; P=.003). No neurologic deterioration, hypotension, falls, or line dislodgments were reported in association with mobilization. A nonsignificant difference in mortality was noted before and after rollout of the algorithm (4% vs 24%, respectively, P=.12). CONCLUSIONS: The implementation of a progressive mobility algorithm was safe and associated with a higher likelihood of mobilization in the first week after spontaneous ICH. Research is needed to investigate methods and the timing for the first mobilization in critically ill stroke patients. PMID- 29580937 TI - Windmill-task as a New Quantitative and Objective Assessment for Mirror Movements in Unilateral Cerebral Palsy: A Pilot Study. AB - OBJECTIVE: To introduce the Windmill-task, a new objective assessment tool to quantify the presence of mirror movements (MMs) in children with unilateral cerebral palsy (UCP), which are typically assessed with the observation-based Woods and Teuber scale (W&T). DESIGN: Prospective, observational, cohort pilot study. SETTING: Children's hospital. PARTICIPANTS: Prospective cohort of children (N=23) with UCP (age range, 6-15y, mean age, 10.5+/-2.7y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The concurrent validity of the Windmill-task is assessed, and the sensitivity and specificity for MM detection are compared between both assessments. To assess the concurrent validity, Windmill-task data are compared with W&T data using Spearman rank correlations (rho) for 2 conditions: affected hand moving vs less affected hand moving. Sensitivity and specificity are compared by measuring the mean percentage of children being assessed inconsistently across both assessments. RESULTS: Outcomes of both assessments correlated significantly (affected hand moving: rho=.520; P=.005; less affected hand moving: rho=.488; P=.009). However, many children displayed MMs on the Windmill-task, but not on the W&T (sensitivity: affected hand moving: 27.5%; less affected hand moving: 40.6%). Only 2 children displayed MMs on the W&T, but not on the Windmill-task (specificity: affected hand moving: 2.9%; less affected hand moving: 1.4%). CONCLUSIONS: The Windmill-task seems to be a valid tool to assess MMs in children with UCP and has an additional advantage of sensitivity to detect MMs. PMID- 29580938 TI - Is 25Hz enough to accurately measure a dynamic change in the ocular accommodation? AB - BACKGROUND: Accommodation is often recorded at a low sampling rate using devices such as autorefractors that are designed to measure the static refractive error. It is therefore important to determine if that resolution is sufficient to accurately measure the dynamic properties of accommodation. The current study provides both theoretical and empirical evidence on the ideal sampling rate necessary to measure a dynamic response. METHODS: Accommodative and disaccommodative step stimuli ranging from 1-3D (1D steps) were presented using a Badal optical system. Responses from 12 children (8-13 years) and 6 adults (20-35 years) were recorded using a dynamic photorefractor (DPR). Fast Fourier transformation was applied to the unsmoothed dynamic responses including position, velocity and acceleration. Also, velocity and acceleration main sequence (MS) characteristics were compared between three photorefractor conditions on 3 subjects. RESULTS: The Nyquist sampling limit necessary to accurately estimate position, velocity and acceleration was at least 5, 10 and 70Hz, respectively. Peak velocity and acceleration were significantly underestimated at a lower rate (p<0.5). However, the slope of MS remained invariant with sampling rate (p>0.5). CONCLUSION: Contrary to the previous findings, a dynamic accommodative response exhibited frequencies larger than 10Hz. Stimulus direction and amplitude had no influence on the frequencies present in the dynamic response. Peak velocity and acceleration can be significantly underestimated when sampled at a lower rate. Taken as a whole, low sampling rate instruments can accurately estimate static accommodation, however, caution needs to be exercised when using them for dynamic accommodation. PMID- 29580939 TI - Non-pharmacological management of a hemodynamically significant patent ductus arteriosus. AB - The association between the patent ductus arteriosus (PDA) and neonatal morbidity, mortality and poor neurodevelopmental outcome in later childhood has been the focus of intense debate for decades. The lack of evidence supporting therapeutic strategies aimed at achieving PDA closure has led to the widespread adoption of conservative management aimed at mitigating the impact of shunt volume without achieving ductal closure. In this article, we review this management approach, describe the supportive evidence and potential complications associated with this strategy. PMID- 29580940 TI - Relationships Among Perceived Functional Capacity, Self-Efficacy, and Disability After Dysvascular Amputation. AB - BACKGROUND: Prosthesis rehabilitation after dysvascular transtibial amputation (TTA) is focused on optimizing functional capacity with limited emphasis on promoting health self-efficacy. Self-efficacy interventions decrease disability for people living with chronic disease, but the influence of self-efficacy on disability is unknown for people with dysvascular TTA. OBJECTIVES: To identify if self-efficacy mediates the relationship between self-reported functional capacity and disability after dysvascular TTA. DESIGN: Cross-sectional, secondary data analysis. SETTING: Outpatient rehabilitation facilities. PARTICIPANTS: Thirty eight men (63.6 +/- 9.1 years old) with dysvascular TTA. METHODS: Participants had been living with an amputation for less than 6 months and using walking as their primary form of locomotion using a prosthesis. The independent variable, functional capacity, was measured using the Prosthesis Evaluation Questionnaire Mobility Scale (PEQ-MS). The proposed mediator, self-efficacy, was measured with the Self-Efficacy of Managing Chronic Disease questionnaire (SEMCD). MAIN OUTCOME MEASURE: Disability was measured using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) questionnaire. RESULTS: The relationship between self-reported functional capacity and disability is partially mediated by self-efficacy. Relationships between WHODAS 2.0 and PEQ-MS (r = -0.61), WHODAS 2.0 and SEMCD (r = -0.51), and PEQ-MS and SEMCD (r = 0.44) were significant (P < .01). Controlling for SEMCD (P = .04), the relationship between PEQ-MS and WHODAS 2.0 remained significant (P < .01). Statistically significant mediation was determined by a bootstrap method for the product of coefficients (95% confidence interval: -2.23, -7.39). CONCLUSIONS: This study provides initial evidence that the relationship between self-reported functional capacity and disability is partially mediated by self-efficacy after dysvascular TTA. The longitudinal effect of self-efficacy should be further examined to identify causal pathways of disability after dysvascular amputation. Furthermore, additional factors contributing to the relationship between self-reported functional capacity and disability need to be identified. LEVEL OF EVIDENCE: III. PMID- 29580941 TI - Increased epoxyeicosatrienoic acids may be part of a protective mechanism in human ulcerative colitis, with increased CYP2J2 and reduced soluble epoxide hydrolase expression. AB - BACKGROUND: Previous preclinical evidence has suggested that the elevation of epoxyeicosatrienoic acids (EETs) derived from the cytochrome P450 (CYP) epoxygenases-dependent metabolism of arachidonic acid has important anti inflammatory effects. However, the levels of EETs and their synthetic and metabolic enzymes in human ulcerative colitis has not been evaluated. METHOD: To evaluate EETs and the expression of relevant CYP isoforms and the metabolizing enzyme, soluble epoxide hydrolase (sEH), tissue biopsies were collected from 16 pairs of ulcerative colitis patients' tissues and matched with adjacent non inflamed tissues. EETs were extracted from tissue homogenates and analyzed by liquid chromatography coupled with tandem mass spectrometry. RESULTS: The concentration of EETs was higher in ulcerative colitis tissues compared with matched adjacent non-inflamed tissues (1.91 +/- 0.98 ng/mg vs. 0.96 +/- 0.77 ng/mg, mean +/- SD, P < 0.01). As shown by immunohistochemistry, sEH was present in the cytoplasm and intestinal mucosa and showed a decline in ulcerative colitis tissues compared with matched adjacent non-inflamed tissues. Western blot analyses showed reduced sEH expression in ulcerative colitis tissues compared with matched adjacent non-inflamed tissues, whereas CYP2J2 increased in ulcerative colitis tissues (P < 0.05). However, there was no statistically significant difference observed in CYP2C8 and CYP2C9 protein expression between them (P > 0.05). CONCLUSION: Our data suggest that the increase in EET levels may be part of a protective mechanism in ulcerative colitis. Furthermore, the concentration of EETs could be a key factor for drug therapy for ulcerative colitis. PMID- 29580942 TI - Targeting the replication stress response in cancer. AB - Many conventional chemotherapies used in cancer treatment exert their effect by inflicting DNA damage. Highly proliferative tissues, as well as tumour cells, are particularly vulnerable to this damage resulting in unwanted toxicities. In contrast, a targeted therapeutic approach has the aim of specifically eliminating cancer cells but with a reduced effect on healthy tissue. New therapies have been developed that target the replication stress response (RSR), a branch of the broader DNA damage response that specifically deals with interferences of the normal DNA replication program. Different pharmaceutical companies have developed inhibitors of the RSR kinases ATR, CHK1 and WEE1, which are currently at different phases of clinical development. Here, we review how the RSR works at the molecular level, what is the rationale for its targeting, and how we envisage its best use in the clinic, based on patient selection and combination therapies supported by in vitro and in vivo preclinical studies. PMID- 29580943 TI - Protein tyrosine kinase 7 regulates extracellular matrix integrity and mesenchymal intracellular RAC1 and myosin II activities during Wolffian duct morphogenesis. AB - Wolffian duct morphogenesis must be highly coordinated with its specialized function of providing an optimal microenvironment for sperm maturation. Without normal Wolffian duct morphogenesis, male infertility will result. Our previous study showed that mediolateral and radial intercalation of epithelial and mesenchymal cells respectively, were major drivers of ductal elongation and were regulated by protein tyrosine kinase 7 (PTK7), a member of the planar cell polarity (PCP) non-canonical Wnt pathway. To understand the mechanism by which PTK7 regulates cell rearrangement/intercalation, we investigated the integrity of the extracellular matrix (ECM) and the activity of intracellular cytoskeleton mediators following loss of Ptk7. Abnormal assembly of nephronectin, laminin, and collagen IV at the basement membrane and fibrosis-like deposition of fibrilla collagen in the interstitium were observed in Ptk7 knockout Wolffian ducts. Further, the activity levels of RAC1 and myosin II, two cytoskeleton mediators, decreased in the Ptk7 knockout mesenchyme compared to controls. In addition, in vitro experiments suggested that alterations of ECM and cytoskeleton mediators resulted in changes in Wolffian duct morphogenesis. When in-vitro-cultured Wolffian ducts were treated with collagenase IV, the degree of cross-linked fibrilla collagen was reduced, Wolffian duct elongation and coiling were significantly reduced, and an expanded cyst-like duct was observed. When Wolffian ducts were treated with RAC1 inhibitor NSC23766, mesenchymal fibrilla collagen was disassembled, and Wolffian duct elongation was significantly reduced. Our findings provide evidence that PTK7 regulates ECM integrity and the activity levels of RAC1 and myosin II, which in turn regulates Wolffian duct morphogenesis and therefore, epididymal function. PMID- 29580944 TI - Inhibition of anthrax lethal factor by ssDNA aptamers. AB - Anthrax is caused by Bacillus anthracis, a bacterium that is able to secrete the toxins protective antigen, edema factor and lethal factor. Due to the high level of secretion from the bacteria and its severe virulence, lethal factor (LF) has been sought as a biomarker for detecting bacterial infection and as an effective target to neutralize toxicity. In this study, we found three aptamers, and binding affinity was determined by fluorescently labeled aptamers. One of the aptamers exhibited high affinity, with a Kd value of 11.0 +/- 2.7 nM, along with low cross reactivity relative to bovine serum albumin and protective antigen. The therapeutic functionality of the aptamer was examined by assessing the inhibition of LF protease activity against a mitogen-activated protein kinase kinase. The aptamer appears to be an effective inhibitor of LF with an IC50 value of 15 +/- 1.5 MUM and approximately 85% cell viability, suggesting that this aptamer provides a potential clue for not only development of a sensitive diagnostic device of B. anthracis infection but also the design of novel inhibitors of LF. PMID- 29580945 TI - Bioavailability and pharmacokinetic profile of grape pomace phenolic compounds in humans. AB - Grape pomace, the major byproduct of the wine and juice industry, is a relevant source of bioactive phenolic compounds. However, polyphenol bioavailability in humans is not well understood, and the inter-individual variability in the production of phenolic metabolites has not been comprehensively assessed to date. The pharmacokinetic and excretive profiles of phenolic metabolites after the acute administration of a drink made from red grape pomace was here investigated in ten volunteers. A total of 35 and 28 phenolic metabolites were quantified in urine and plasma, respectively. The main circulating metabolites included phenyl gamma-valerolactones, hydroxybenzoic acids, simple phenols, hydroxyphenylpropionic acids, hydroxycinnamates, and (epi)catechin phase II conjugates. A high inter-individual variability was shown both in urine and plasma samples, and different patterns of circulating metabolites were unravelled by applying unsupervised multivariate analysis. Besides the huge variability in the production of microbial metabolites of colonic origin, an important variability was observed due to phase II conjugates. These results are of interest to further understand the potential health benefits of phenolic metabolites on individual basis. PMID- 29580946 TI - Research trends in flavonoids and health. AB - Herein we describe, based on some bibliometric data, how the field of research on flavonoids has evolved over the last 25 years. The number of papers on flavonoids has risen in an exponential manner over these years, much faster than other fields on food constituents. This increase appears to be related to the contemporary explosion of interest in healthy foods, supplements and nutraceuticals. It was also probably triggered by large epidemiological studies on fruits and vegetables, and particularly on flavonoids, consumption and incidence of cancer, stroke and coronary heart disease. The widely distributed flavonols constitute the flavonoid subgroup upon which the greatest interest has been focused, followed by flavanols and more recently by anthocyanidins and other related polyphenols such as resveratrol. Research on isoflavones rapidly emerged in the 1990s but plateaued in the 2000s. In the 1990s flavonoids were mainly considered as the active components of medicinal plants, while from 2000 onward, they switched to be mainly regarded as bioactive food ingredients. We envision a continuation in the growth of research for the coming decade focused on clearly demonstrating the importance of flavonoids for human health. PMID- 29580947 TI - A mass spectrometry approach for the identification and localization of small aldehyde modifications of proteins. AB - Lipids containing polyunsaturated fatty acids are primary targets of oxidation, which produces reactive short-chain aldehydes that can covalently modify proteins, a process called lipoxidation. Improved mass spectrometry (MS) methods for the analysis of these adducts in complex biological systems are needed. Lysozyme and human serum albumin (HSA) were used as model proteins to investigate lipoxidation products formed by two short-chain aldehydes, acrolein and pentanal, which are unsaturated and saturated aldehydes respectively. The adducts formed were stabilized by NaBH4 or NaBH3CN reduction and analysed by MS. Analysis of intact modified lysozyme showed a pentanal modification resulting from Schiff's base formation (+70 Da), and up to 8 acrolein adducts, all resulting from Michael addition (+58 Da). Analysis of tryptic digests identified specific histidine, cysteine and lysine residues modified in both lysozyme and HSA, and determined characteristic amino acid-specific fragmentations. Eight different internal fragment ions were found that could be used as general diagnostic ions for pentanal- and acrolein-modified amino acids. The combined use of intact protein analysis and LC-MS/MS methods provided a powerful tool for the identification and localization of aldehyde-protein adducts, and the diagnostic ions will facilitate the development of targeted MS methods for analysis of adducts in more complex samples. PMID- 29580948 TI - Tubeimoside V sensitizes human triple negative breast cancer MDA-MB-231 cells to anoikis via regulating caveolin-1-related signaling pathways. AB - Metastatic triple-negative breast cancer (TNBC) has poor outcome with conventional chemotherapy regimens due to its aggressive behavior. The acquisition of anoikis resistance, a programmed cell death process triggered by substratum detachment, is an important mechanism in TNBC metastasis. Therefore, agents that can restore the sensitivity of cancer cells to anoikis may be helpful for the treatment of metastatic TNBC. In this study, we investigated the inhibitory effect of Tubeimosides V (TBMS-V), a cyclic bisdesmoside isolated from the ethanol extracts of tubers of B. paniculatum., on anoikis resistance and the involvement of caveolin-1(CAV-1)-related signaling pathways in such process in MDA-MB-231 cells. The results showed that the treatment of TBMS-V could sensitize cancer cells to anoikis, which was associated with suppression of anchorage independent culture-induced CAV-1 overexpression, EGFR activation as well as ITGB1-FAK activation. The data from this study might contribute to providing a potential therapeutic target for metastatic TNBC and suggest the possibility of TBMS-V and its derivatives for metastatic TNBC therapy. PMID- 29580949 TI - LEC1 (NF-YB9) directly interacts with LEC2 to control gene expression in seed. AB - The LAFL transcription factors LEC2, ABI3, FUS3 and LEC1 are master regulators of seed development. LEC2, ABI3 and FUS3 are closely related proteins that contain a B3-type DNA binding domain. We have previously shown that LEC1 (a NF-YB type protein) can increase LEC2 and ABI3 but not FUS3 activity. Interestingly, FUS3, LEC2 and ABI3 contain a B2 domain, the function of which remains elusive. We showed that LEC1 and LEC2 partially co-localised in the nucleus of developing embryos. By comparing protein sequences from various species, we identified within the B2 domains a set of highly conserved residues (i.e. TKxxARxxRxxAxxR). This domain directly interacts with LEC1 in yeast. Mutations of the conserved amino acids of the motif in the B2 domain abolished this interaction both in yeast and in moss protoplasts and did not alter the nuclear localisation of LEC2 in planta. Conversely, the mutations of key amino acids for the function of LEC1 in planta (D86K) prevented the interaction with LEC2. These results provide molecular evidences for the binding of LEC1 to B2-domain containing transcription factors, to form heteromers, involved in the control of gene expression. PMID- 29580950 TI - The Value of Early Depth of Response in Predicting Long-Term Outcome in EGFR Mutant Lung Cancer. AB - INTRODUCTION: Traditionally, marked tumor shrinkage has been assumed to portend better outcome. We investigated whether depth of tumor response was associated with improved survival outcomes in advanced EGFR-mutant NCLC. METHODS: Individual patient data from randomized trials (EURTAC, IPASS, ENSURE, LUX-Lung 3, and LUX Lung 6) were used. The association of depth of response with progression-free survival (PFS) and overall survival was examined using landmark analyses. Depth of response based on radiologic assessments at 6 weeks and 12 weeks was calculated as the relative changes in the sum of the longest diameters of the target lesions from baseline. RESULTS: Of 1081 evaluable patients at 6 weeks with no disease progression, 71.2% achieved Response Evaluation Criteria in Solid Tumors response. Using a landmark analysis, EGFR-TKI was more effective than chemotherapy (PFS hazard ratio = 0.36, p < .0001); and was associated with greater mean tumor shrinkage than chemotherapy (35.1% versus 18.5%, p < .0001). However, there was no significant difference in the relative PFS benefit between treatment groups across the entire spectrum of tumor shrinkage (p = .18 for test of interaction between treatment and continuously measured depth of response). Depth of response at 6 weeks was not associated with PFS when adjusted for treatment effect (hazard ratio = 0.96, p = .78). Similar results were obtained for 12-week landmark analysis and for OS outcome. CONCLUSIONS: The PFS advantage of EGFR-TKI over chemotherapy in advanced EGFR mutant NCLC is not explained by depth of response at 6 or 12 weeks. It should not be used as a surrogate of benefit in future trials or routine clinical decision making.

AB - Morphine induces peripherally MU-opioid-mediated antinociception to heat but not to mechanical stimulation. Peripheral sigma-1 receptors tonically inhibit MU opioid antinociception to mechanical stimuli, but it is unknown whether they modulate MU-opioid heat antinociception. We hypothesized that sigma-1 receptors might play a role in the modality-specific peripheral antinociceptive effects of morphine and other clinically relevant MU-opioid agonists. Mechanical nociception was assessed in mice with the paw pressure test (450 g), and heat nociception with the unilateral hot plate (55 degrees C) test. Local peripheral (intraplantar) administration of morphine, buprenorphine or oxycodone did not induce antinociception to mechanical stimulation but had dose-dependent antinociceptive effects on heat stimuli. Local sigma-1 antagonism unmasked peripheral antinociception by MU-opioid agonists to mechanical stimuli, but did not modify their effects on heat stimulation. TRPV1+ and IB4+ cells are segregated populations of small neurons in the dorsal root ganglia (DRG) and the density of sigma-1 receptors was higher in IB4+ cells than in the rest of small nociceptive neurons. The in vivo ablation of TRPV1-expressing neurons with resiniferatoxin did not alter IB4+ neurons in the DRG, mechanical nociception, or the effects of sigma-1 antagonism on local morphine antinociception in this type of stimulus. However, it impaired the responses to heat stimuli and the effect of local morphine on heat nociception. In conclusion, peripheral opioid antinociception to mechanical stimuli is limited by sigma-1 tonic inhibitory actions, whereas peripheral opioid antinociception to heat stimuli (produced in TRPV1-expressing neurons) is not. Therefore, sigma-1 receptors contribute to the modality-specific peripheral effects of opioid analgesics. PMID- 29580952 TI - Brain tissue oxygen regulation in awake and anesthetized neonates. AB - Inhaled general anesthetics are used commonly in adults and children, and a growing body of literature from animals and humans suggests that exposure to anesthesia at an early age can impact brain development. While the origin of these effects is not well understood, it is known that anesthesia can disrupt oxygen regulation in the brain, which is critically important for maintaining healthy brain function. Here we investigated how anesthesia affected brain tissue oxygen regulation in neonatal rabbits by comparing brain tissue oxygen and single unit activity in the awake and anesthetized states. We tested two common general anesthetics, isoflurane and sevoflurane, delivered in both air and 80% oxygen. Our findings show that general anesthetics can greatly increase brain tissue PO2 in neonates, especially when combined with supplemental oxygen. Although isoflurane and sevoflurane belong to the same class of anesthetics, notable differences were observed in their effects upon neuronal activity and spontaneous respiration. Our findings point to the need to consider the potential effects of hyperoxia when supplemental oxygen is utilized, particularly in children and neonates. PMID- 29580953 TI - Effects of drugs of abuse on channelrhodopsin-2 function. AB - Channelrhodopsins are light activated ion channels used extensively over the past decade to probe the function of genetically defined neuronal populations and distinct neural circuits with high temporal and spatial precision. The widely used Channelrhodopsin-2 variant (ChR2) is an excitatory opsin that undergoes conformational changes in response to blue light, allowing non-selective passage of protons and cations across the plasma membrane thus leading to depolarization. In the addiction neuroscience field, opsins such as ChR2 provide a means to disambiguate the overlapping circuitry involved in mediating the reinforcing and aversive effects of drugs of abuse as well as to determine the plasticity that can occur in these circuits during the development of dependence. Although ChR2 has been widely used in animal models of drug and alcohol self-administration, direct effects of drugs of abuse on ChR2 function may confound its use and lead to misinterpretation of data. As a variety of neuronal ion channels are primary targets of various drugs of abuse, it is critical to determine whether ChR2 mediated currents are modulated by these drugs. In this study, we performed whole cell electrophysiological recordings in HEK293 cells expressing the commonly used ChR2(H134R) variant and examined the effects of various drugs of abuse and other commonly used agents on light-induced currents. We found no differences in ChR2 mediated currents in the presence of 30 MUM nicotine, 30 MUM cocaine, 100 MUM methamphetamine or 3 mM toluene. Similarly, ChR2 currents were insensitive to 30 mM ethanol but higher concentrations (100-300 mM) produced significant effects on the desensitization and amplitude of light-evoked currents. Tetrahydrocannabinol (1-10 MUM) and morphine (30-100 MUM) significantly inhibited ChR2 currents while the cannabinoid receptor antagonist AM-251 had no effect. The sodium channel blocker tetrodotoxin (5 MUM) and the generic channel blocker/contrast agent gadolinium chloride (10 mM) also reduced ChR2 currents while the divalent ion magnesium (10 mM) had no effect. Together, the results from this study highlight the importance of conducting appropriate control experiments when testing new compounds in combination with optogenetic approaches. PMID- 29580954 TI - Assessing "chaotic eating" using self-report and the UK Adult National Diet and Nutrition Survey: No association between BMI and variability in meal or snack timings. AB - Although regular meal timings are recommended for weight loss, no study has characterised irregularity in the timing of eating occasions or investigated associations with body-mass index (BMI). Here, we characterise "chaotic eating" as the tendency to eat at variable times of day. In two studies, we used a novel measure to explore the relationship between BMI and chaotic eating. In Study 1 (N = 98) we measured BMI and used a self-report measure to assess the usual range of times that meals and snacks are consumed over a seven-day period, as well as meal and snack frequency. A separate meal and snack 'chaotic eating index' was derived from the number of possible thirty-minute snack- or meal-slots, divided by the frequency of these eating events. After adjusting for age, gender, and dietary habits (Three-Factor Eating Questionnaire) we found no relationship between BMI and chaotic eating of meals (beta = -0.07, p = 0.73) or snacks (beta = -0.10, p = 0.75). In Study 2, we calculated the same chaotic eating index (meals and snacks) using data from the UK National Diet and Nutrition Survey of adults 2000-2001 (seven-day diet diaries; N = 1175). Again, we found little evidence that BMI is associated with chaotic eating of meals (beta = 0.16, p = 0.27) or snacks (beta = 0.15, p = 0.12). Together, these results suggest that irregular eating timings do not promote weight gain and they challenge guidelines that recommend regularity in meal timings for weight loss. PMID- 29580955 TI - Intraepithelial corneal haemorrhage in a rigid contact lens wearer. AB - Intracorneal haemorrhage is a rare complication of modern contact lens wear. While a limited number of reports have described intracorneal haemorrhages (typically stromal) associated with the extended wear of soft contact lenses with limited oxygen permeability for the correction of aphakia, this case report documents the management and resolution of a significant intraepithelial corneal haemorrhage associated with long-term rigid contact lens wear for keratoconus and high myopia. PMID- 29580956 TI - The use of miltefosine in the management of refractory Acanthamoeba keratitis. AB - Acanthamoeba keratitis (AK) is a sight threatening infection most commonly affecting contact lens wearers. The authors report a case of intractable A.polyphaga and A.castellanii, with extensive intraocular spread, managed using oral miltefosine. A 59-year old male contact lens wearer was referred to the tertiary corneal service at Bristol Eye Hospital. Vision was hand movements on the left and 6/6 on the right. Clinical examination was consistent with left AK (confirmed by corneal scrape). Management included biguanide (polyhexamethylene biguanide (PHMB) 0.02%, later 0.06%) and diamidine (hexamidine 0.1%). Further treatment included imidazole (guttae voriconazole, oral posaconazole) and fortified biguanide (chlorhexidine 0.2%). Therapeutic PKP was performed. Microscopy revealed Acanthamoeba throughout host stroma. Corneal scrape and anterior chamber tap revealed persistent infection with Acanthamoeba. Intracameral voriconazole was administered twice. Clinically there was scleritis, with concerns regarding posterior segment involvement. There was a severe necrotic keratitis with almost complete corneal melt, requiring enucleation. Oral miltefosine was commenced to reduce the risk of transmission of Acanthamoeba beyond ocular structures at the time of the enucleation. Histopathological analysis detected A.polyphaga and A.castellanii in vitreous but not retina, choroid or optic nerve suggesting that infection had not progressed posteriorly through the ocular structures and the central nervous system was not involved. The use of miltefosine as a component of combination anti-parasitic therapy is associated with long-term survival in cases of Acanthamoeba infection of the central nervous system. This case reports its first systemic use in the United Kingdom in a case of severe intractable AK with intraocular spread. PMID- 29580957 TI - Alamandine injected into the paraventricular nucleus increases blood pressure and sympathetic activation in spontaneously hypertensive rats. AB - Alamandine is a newly discovered new component of the renin-angiotensin (Ang) system (RAS) that has been shown to exert vasoactive effects in some areas of the nervous system. The present study investigated whether administration of alamandine to the hypothalamic paraventricular nucleus (PVN) modulates blood pressure and sympathetic activity. Mean arterial pressure (MAP) and renal sympathetic nerve activity (RSNA) were recorded in anaesthetized rats. PVN microinjection of alamandine increased MAP and RSNA both in Wistar-Kyoto (WKY) rats and in spontaneously hypertensive rats (SHRs), but to a greater extent in SHRs. Moreover, these effects were blocked by pretreatment with alamandine receptor Mas-related G-protein-coupled receptor, member D (MrgD) antagonist D Pro7-Ang-(1-7), adenylyl cyclase (AC) inhibitor SQ22536, and protein kinase A (PKA) inhibitor rp-adenosine-3',5'-cyclic monophosphorothionate (Rp-cAMP). Treatment with D-Pro7-Ang-(1-7), SQ22536, or Rp-cAMP alone in PVN decreased MAP and RSNA in the SHRs. Conversely cAMP alone increased MAP and RSNA, and pretreatment with cAMP enhanced alamandine's effects. These results indicate that microinjection of alamandine into the PVN increases blood pressure and sympathetic outflow via MrgD and the cAMP-PKA pathway. PMID- 29580959 TI - Repetitive versus standard tactile stimulation of preterm infants at birth - A randomized controlled trial. AB - AIM: To evaluate the direct effect of repetitive tactile stimulation on breathing effort of preterm infants at birth. METHODS: This randomized controlled trial compared the effect of repetitive stimulation on respiratory effort during the first 4 min after birth with standard stimulation based on clinical indication in preterm infants with a gestational age of 27-32 weeks. All details of the stimulation performed were noted. The main study parameter measured was respiratory minute volume, other study parameters assessed measures of respiratory effort; tidal volumes, rate of rise to maximum tidal volumes, percentage of recruitment breaths, and oxygenation of the infant. RESULTS: There was no significant difference in respiratory minute volume in the repetitive stimulation group when compared to the standard group. Oxygen saturation was significantly higher (87.6 +/- 3.3% vs 81.7 +/- 8.7%, p = .01) while the amount of FiO2 given during transport to the NICU was lower (28.2 (22.8-35.0)% vs 33.6 (29.4-44.1)%, p = .04). There was no significant difference in administration of positive pressure ventilation (52% vs 78%, p = .13), or the duration of ventilation (median (IQR) time 8 (0-118)s vs 35 (13-131)s, p = .23). Caregivers decided less often to administer caffeine in the delivery room to stimulate breathing in the repetitive stimulation group (10% vs 39%, p = .036). CONCLUSION: Although the increase in respiratory effort during repetitive stimulation did not reach significance, oxygenation significantly improved with a lower level of FiO2 at transport to the NICU. Repetitive tactile stimulation could be of added value to improve breathing effort at birth. PMID- 29580958 TI - Cerebral saturation in cardiac arrest patients measured with near-infrared technology during pre-hospital advanced life support. Results from Copernicus I cohort study. AB - AIM: To date, monitoring options during pre-hospital advanced life support (ALS) are limited. Regional cerebral saturation (rSO2) may provide more information concerning the brain during ALS. We hypothesized that an increase in rSO2 during ALS in out-of hospital cardiac arrest (OHCA) patients is associated with return of spontaneous circulation (ROSC). METHODS: A prospective, non-randomized multicenter study was conducted in the pre-hospital setting of six hospitals in Belgium. Cerebral saturation was measured during pre-hospital ALS by a medical emergency team in OHCA patients. Cerebral saturation was continuously measured until ALS efforts were terminated or until the patient with sustained ROSC (>20 min) arrived at the emergency department. To take the longitudinal nature of the data into account, a linear mixed model was used. The correlation between the repeated measures of a patient was handled by means of a random intercept and a random slope. Our primary analysis tested the association of rSO2 with ROSC. RESULTS: Of the 329 patients 110 (33%) achieved ROSC. First measured rSO2 was 30% +/- 18 in the ROSC group and 24% +/- 15 in the no-ROSC group (p = .004; mean +/- SD). Higher mean rSO2 values were observed in the ROSC group compared to the no ROSC group (41% +/- 13 versus 33% +/- 13 respectively; p < 0.001). The median increase in rSO2, measured from start until two minutes before ROSC, was higher in the ROSC group (ROSC group 17% (IQR 6-29)) than in the no-ROSC group (8% (IQR 2-13); p < 0.001). An increase in rSO2 above 15% was associated with ROSC (OR 4.5; 95%CI 2.747-7.415; p < 0.001). CONCLUSION: Regional cerebral saturation measurements can be used during pre-hospital ALS as an additional marker to predict ROSC. An increase of at least 15% in rSO2 during ALS is associated with a higher probability of ROSC. PMID- 29580960 TI - Prediction and risk stratification of survival in accidental hypothermia requiring extracorporeal life support: An individual patient data meta-analysis. AB - BACKGROUND: Extra-corporeal life support (ECLS) is a life-saving intervention for patients with hypothermia induced cardiac arrest or severe cardiovascular instability. However, its application is highly variable due to a paucity of data in the literature to guide practice. Current guidelines and recommendations are based on expert opinion, single case reports, and small case series. Combining all of the published data in a patient-level analysis can provide a robust assessment of the influence of patient characteristics on survival with ECLS. OBJECTIVE: To develop a prediction model of survival with good neurologic outcome for accidental hypothermia treated with ECLS. METHODS: Electronic searches of PubMed, EMBASE, CINAHL were conducted with a hand search of reference lists and major surgical and critical care conference abstracts. Studies had to report the use of ECLS configured with a circuit, blood pump and oxygenator with an integrated heat exchanger. Randomized and observational studies were eligible for inclusion. Non-human, non-English and review manuscripts were deemed ineligible. Study authors were requested to submit patient level data when aggregate or incomplete individual patient data was provided in a study. Survival with good neurologic outcome was categorized for patients to last follow-up based on the reported scores on the Cerebral Performance Category (1 or 2), Glasgow Outcome Scale (4 or 5) and Pediatric Overall Performance Category (1 or 2). A one-stage, individual patient data meta-analysis was performed with a mixed-effects multi level logistic regression model reporting odds ratio (OR) with a 95% confidence interval (CI). RESULTS: Data from 44 observational studies and 40 case reports (n = 658) were combined and analyzed to identify independent predictors of survival with good neurologic outcome. The survival rate with good neurologic outcome of the entire cohort was 40.3% (265 of 658). ECLS rewarming rate (OR: 0.93; 95% CI: 0.88, 0.98; p = .007), female gender (OR: 2.78; 95% CI: 1.69, 4.58; p < 0.001), asphyxiation (OR: 0.19; 95% CI: 0.11, 0.35; p < 0.001) and serum potassium (OR: 0.62; 95% CI: 0.53, 0.73; p < 0.001) were associated with survival with a good neurologic outcome. The logistic regression model demonstrated excellent discrimination (c-statistic: 0.849; 95% CI: 0.823, 0.875). CONCLUSIONS: The use of extracorporeal life support in the treatment of hypothermic cardiac arrest provides a favourable chance of survival with good neurologic outcome. When used in a weighted scoring system, asphyxiation, serum potassium and gender can help clinicians prognosticate the benefit of resuscitating hypothermic patients with ECLS. PMID- 29580961 TI - Childhood aggression: A synthesis of reviews and meta-analyses to reveal patterns and opportunities for prevention and intervention strategies. AB - This study provides a synthesis of meta-analyses and systematic reviews on non pharmacological treatments for childhood aggression. Treatments referred to universal prevention, selective prevention, indicated prevention, or intervention (Mrazek and Haggerty, 1994). Seventy-two meta-analyses and systematic reviews met the inclusion criteria. We describe their characteristics, effect sizes across types of treatments, and the effects of various moderators. For universal and selective prevention, effects were mostly absent or small; for indicated prevention and interventions, effects were mostly small or medium. Only two moderators had a positive effect on treatment effectiveness, namely pre-test levels of aggression and parental involvement. These results identified similarities between indicated prevention and intervention treatments, on the one hand, and universal prevention and selective prevention, on the other. Our findings suggest that research distinguishing between targets of treatments (i.e., factors associated with childhood aggression vs. present aggressive behaviors) would be promising. Moreover, to further increase effectiveness of treatments for childhood aggression, individual differences warrant scientific attention. PMID- 29580962 TI - Acute Changes in Electrophysiological Properties of Cortical Regular-Spiking Cells Following Seizures in a Rat Lithium-Pilocarpine Model. AB - Profound alterations in both the synaptic and intrinsic membrane properties of neurons that increase the neuronal network excitability are found in epileptic tissue. However, there are still uncertainties regarding the kind of changes in the intrinsic membrane properties occurring during epileptogenesis. Epileptogenesis is typically triggered by the initial brain-damaging insult, and status epilepticus (SE) is one of such insults. In the present study, we explored the acute changes in the intrinsic membrane properties of pyramidal cells one day after SE in a rat lithium-pilocarpine model. Using whole-cell patch-clamp recording and the dynamic-clamp technique, we investigated the properties of regular-spiking neurons in the entorhinal cortex (EC) and the medial prefrontal cortex (PFC), two areas differentially affected by SE. We found that one day after SE: (1) the intrinsic membrane properties of EC neurons are significantly altered, while the properties of PFC neurons are mostly unchanged; (2) the input resistance and membrane time constant of regular-spiking neurons are reduced due to enhanced leak current; (3) the active membrane properties of neurons are mostly unaffected; and (4) changes in the passive membrane properties diminish the intrinsic neuronal excitability. Therefore, our results suggest that the acute changes in the intrinsic membrane properties of entorhinal neurons following pilocarpine-induced SE do not contribute to network hyperexcitability. In contrast, at the early stage of epileptogenesis, protective homeostatic plasticity of intrinsic membrane properties is observed in the EC; it reduces the neuronal excitability in response to increased network excitability. PMID- 29580963 TI - Neurovascular Coupling During Visual Stimulation in Multiple Sclerosis: A MEG fMRI Study. AB - The process of neurovascular coupling ensures that increases in neuronal activity are fed by increases in cerebral blood flow. Evidence suggests that neurovascular coupling may be impaired in Multiple Sclerosis (MS) due to a combination of brain hypoperfusion, altered cerebrovascular reactivity and oxygen metabolism, and altered levels of vasoactive compounds. Here, we tested the hypothesis that neurovascular coupling is impaired in MS. We characterized neurovascular coupling as the relationship between changes in neuronal oscillatory power within the gamma frequency band (30-80 Hz), as measured by magnetoencephalography (MEG), and associated hemodynamic changes (blood oxygenation level dependent, BOLD, and cerebral blood flow, CBF) as measured by functional MRI. We characterized these responses in the visual cortex in 13 MS patients and in 10 matched healthy controls using a reversing checkerboard stimulus at five visual contrasts. There were no significant group differences in visual acuity, P100 latencies, occipital gray matter (GM) volumes and baseline CBF. However, in the MS patients we found a significant reduction in peak gamma power, BOLD and CBF responses. There were no significant differences in neurovascular coupling between groups, in the visual cortex. Our results suggest that neuronal and vascular responses are altered in MS. Gamma power reduction could be an indicator of GM dysfunction, possibly mediated by GABAergic changes. Altered hemodynamic responses confirm previous reports of a vascular dysfunction in MS. Despite altered neuronal and vascular responses, neurovascular coupling appears to be preserved in MS, at least within the range of damage and disability studied here. PMID- 29580964 TI - Obstetric patients' health-related quality of life before and after intensive care. AB - BACKGROUND: Intensive care admissions during pregnancy, childbirth, and postpartum period are relatively well investigated. However, very little is known about these obstetric patients' health-related quality of life (HRQoL) before and after critical care. OBJECTIVE: The objective of this study was to assess obstetric patients' HRQoL before intensive care admission (baseline) and at 6 months after discharge (follow-up) DESIGN: This was a retrospective database study. In a 5-year period, the data of all women admitted to the intensive care unit (ICU) during pregnancy, delivery, or up to 42 days postpartum were analysed. METHODS: Four multidisciplinary ICUs of Finnish University hospitals participated. The HRQoL was assessed using the EuroQol-5D (EQ-5D) instrument with utility score (EQsum) and visual analogue scale (EQ-VAS). RESULTS: A total of 283 obstetric patients were identified from the clinical information system. Of these, 99 (35%) completed the EQ-5D questionnaires both at baseline and follow up, and 65 of them (23%) completed EQ-VAS. The comparison of patients' EQsum scores before intensive care admission and after discharge showed that patients' HRQoL remained good (0.970 vs 0.972) (max 1.0) or increased (0.788 vs 0.982) in 80.8% of the patients. Patients reported improved overall health on the EQ-VAS at 6 months follow-up (EQ-VAS mean, 71.86 vs 88.20; p <= 0.001) (max 100). However, 19.2% of the patients had lower HRQoL (EQsum mean 0.987 vs 0.798) at follow-up. Following intensive care, 15% of the patients had more pain/discomfort, and 11% expressed more depression/anxiety. Multiparous patients were more likely to suffer from worsened depression/anxiety (p = 0.024). CONCLUSION: In the majority of the obstetric patients, HRQoL at 6 months follow-up remained good or had increased from baseline. However, nearly one-fifth of the patients had impaired HRQoL after discharge. Thus, intensive care management should take in to consideration follow-up program after intensive care of ICU-admitted obstetric patients. PMID- 29580965 TI - Designing a nurse-delivered delirium bundle: What intensive care unit staff, survivors, and their families think? AB - BACKGROUND: Implementation of quality improvement interventions can be enhanced by exploring the perspectives of those who will deliver and receive them. We designed a non-pharmacological bundle for delirium management for a feasibility trial, and we sought to obtain the views of intensive care unit (ICU) staff, survivors, and families on the barriers and facilitators to its implementation. OBJECTIVE: The objective of this study is to determine the barriers and facilitators to a multicomponent bundle for delirium management in critically ill patients comprising (1) education and family participation, (2) sedation minimisation and pain, agitation, and delirium protocol, (3) early mobilisation, and (4) environmental interventions for sleep, orientation, communication, and cognitive stimulation. METHODS: Nine focus group interviews were conducted with ICU staff (n = 68) in 12 UK ICUs. Three focus group interviews were conducted with ICU survivors (n = 12) and their family members (n = 2). Interviews were digitally recorded, transcribed, and thematically analysed using the Braun and Clarke framework. RESULTS: Overall, staff, survivors, and their families agreed the bundle was acceptable. Facilitating factors for delivering the bundle were staff and relatives' education about potential benefits and encouraging family presence. Facilitating factors for sedation minimisation were evening ward rounds, using non-verbal pain scores, and targeting sedation scores. Barriers identified by staff were inadequate resources, poor education, relatives' anxiety, safety concerns, and ICU culture. Concerns were raised about patient confidentiality when displaying orientation materials and managing resources for early mobility. Survivors cited that flexible visiting and re-establishing normality were important factors; and staff workload, lack of awareness, and poor communication were factors that needed to be considered before implementation. CONCLUSION: Generally, the bundle was deemed acceptable and deliverable. However, like any complex intervention, component adaptations will be required depending on resources available to the ICU; in particular, involvement of pharmacists in the ward round and physiotherapists in mobilising intubated patients. PMID- 29580966 TI - Hand hygiene compliance and behavioural determinants in a paediatric intensive care unit: An observational study. AB - BACKGROUND: Hand hygiene is considered the single most effective means of reducing healthcare-associated infections, but improving and sustaining hand hygiene compliance remains a great challenge. OBJECTIVES: To compare hand hygiene compliance before and after interventions to promote adherence in a paediatric intensive care unit (PICU) and to identify predictors of intention to perform the behaviour "hand hygiene during patient care in the PICU". METHODS: A before and after study was conducted in three phases. Based on the World Health Organization guideline for hand hygiene compliance monitoring, 1261 hand hygiene opportunities were directly observed during routine patient care by two observers simultaneously, in a nine-bed PICU in Brazil, before and after infrastructure and educational interventions. To identify predictors of healthcare professionals' intention to perform the behaviour hand hygiene during patient care, a data collection instrument was designed based on the Theory of Planned Behaviour. Statistical analyses were undertaken using Chi-square test or the Fisher's exact test and regression analysis. A significance level of 5% (p < 0.05) was applied to all analyses. RESULTS: The hand hygiene compliance rate increased significantly from 27.3% in the "pre-intervention phase" to 33.1% in "phase 1 post-intervention," to 37.0% in "phase 2-post-intervention" (p = .010). Perceived social pressure (p = .026) was a determinant factor of intention to perform the behaviour. CONCLUSIONS: Hand hygiene compliance raised significantly after infrastructure, educational, and performance feedback interventions. However, despite the significant effect of the implemented interventions, the overall hand hygiene compliance rate was low. Perceived social pressure characterised a determinant factor of intention to perform the behaviour "hand hygiene during patient care in the PICU", reinforcing the need for behaviour determinants analysis when designing promotional interventions. PMID- 29580967 TI - Interleaved quantitative BOLD: Combining extravascular R2' - and intravascular R2 measurements for estimation of deoxygenated blood volume and hemoglobin oxygen saturation. AB - Quantitative BOLD (qBOLD), a non-invasive MRI method for assessment of hemodynamic and metabolic properties of the brain in the baseline state, provides spatial maps of deoxygenated blood volume fraction (DBV) and hemoglobin oxygen saturation (HbO2) by means of an analytical model for the temporal evolution of free-induction-decay signals in the extravascular compartment. However, mutual coupling between DBV and HbO2 in the signal model results in considerable estimation uncertainty precluding achievement of a unique set of solutions. To address this problem, we developed an interleaved qBOLD method (iqBOLD) that combines extravascular R2' and intravascular R2 mapping techniques so as to obtain prior knowledge for the two unknown parameters. To achieve these goals, asymmetric spin echo and velocity-selective spin-labeling (VSSL) modules were interleaved in a single pulse sequence. Prior to VSSL, arterial blood and CSF signals were suppressed to produce reliable estimates for cerebral venous blood volume fraction (CBVv) as well as venous blood R2 (to yield HbO2). Parameter maps derived from the VSSL module were employed to initialize DBV and HbO2 in the qBOLD processing. Numerical simulations and in vivo experiments at 3 T were performed to evaluate the performance of iqBOLD in comparison to the parent qBOLD method. Data obtained in eight healthy subjects yielded plausible values averaging 60.1 +/- 3.3% for HbO2 and 3.1 +/- 0.5 and 2.0 +/- 0.4% for DBV in gray and white matter, respectively. Furthermore, the results show that prior estimates of CBVv and HbO2 from the VSSL component enhance the solution stability in the qBOLD processing, and thus suggest the feasibility of iqBOLD as a promising alternative to the conventional technique for quantifying neurometabolic parameters. PMID- 29580969 TI - Unconventional secretion of transmembrane proteins. AB - Over the past 20 years it has become evident that eukaryotic cells utilize both conventional and unconventional pathways to deliver proteins to their target sites. Most proteins with a signal peptide and/or a transmembrane domain are conventionally transported through the endoplasmic reticulum to the Golgi apparatus and then to the plasma membrane. However, an increasing number of both soluble cargos (Type I, II, and III) and integral membrane proteins (Type IV) have been found to reach the plasma membrane via unconventional protein secretion (UPS) pathways that bypass the Golgi apparatus under certain conditions, such as cellular stress or development. Well-known examples of transmembrane proteins that undergo Type IV UPS pathways are position-specific antigen subunit alpha 1 integrin, cystic fibrosis transmembrane conductance regulator, myeloproliferative leukemia virus oncogene, and pendrin. Although we collectively refer to all Golgi bypassing routes as UPS, individual trafficking pathways are diverse compared to the conventional pathways, and the molecular mechanisms of UPS pathways are not yet completely defined. This review summarizes the intracellular trafficking pathways of UPS cargo proteins, particularly those with transmembrane domains, and discusses the molecular machinery involved in the UPS of transmembrane proteins. PMID- 29580968 TI - Correlation of neural activity with behavioral kinematics reveals distinct sensory encoding and evidence accumulation processes during active tactile sensing. AB - Many real-world decisions rely on active sensing, a dynamic process for directing our sensors (e.g. eyes or fingers) across a stimulus to maximize information gain. Though ecologically pervasive, limited work has focused on identifying neural correlates of the active sensing process. In tactile perception, we often make decisions about an object/surface by actively exploring its shape/texture. Here we investigate the neural correlates of active tactile decision-making by simultaneously measuring electroencephalography (EEG) and finger kinematics while subjects interrogated a haptic surface to make perceptual judgments. Since sensorimotor behavior underlies decision formation in active sensing tasks, we hypothesized that the neural correlates of decision-related processes would be detectable by relating active sensing to neural activity. Novel brain-behavior correlation analysis revealed that three distinct EEG components, localizing to right-lateralized occipital cortex (LOC), middle frontal gyrus (MFG), and supplementary motor area (SMA), respectively, were coupled with active sensing as their activity significantly correlated with finger kinematics. To probe the functional role of these components, we fit their single-trial-couplings to decision-making performance using a hierarchical-drift-diffusion-model (HDDM), revealing that the LOC modulated the encoding of the tactile stimulus whereas the MFG predicted the rate of information integration towards a choice. Interestingly, the MFG disappeared from components uncovered from control subjects performing active sensing but not required to make perceptual decisions. By uncovering the neural correlates of distinct stimulus encoding and evidence accumulation processes, this study delineated, for the first time, the functional role of cortical areas in active tactile decision-making. PMID- 29580970 TI - Role of autophagy in IL-1beta export and release from cells. AB - The autophagy pathway known also as macroautophagy (herein referred to as autophagy) is characterized by the formation of double-membrane organelles that capture cytosolic material. Based on pathway termination alternatives, autophagy has been divided into degradative and secretory. During degradative autophagy, autophagosomes typically fuse with lysosomes upon which the sequestered material is degraded. During secretory autophagy, instead of degradation the sequestered cargo is subjected to active secretion or passive release. In this review, we focus on the mechanisms of secretion/passive release of the potent pro inflammatory cytokine IL-1beta, as a prototypical leaderless cytosolic protein cargo studied in the context of secretory autophagy. PMID- 29580972 TI - Making reliable negative predictions of human skin sensitisation using an in silico fragmentation approach. AB - A previously published fragmentation method for making reliable negative in silico predictions has been applied to the problem of predicting skin sensitisation in humans, making use of a dataset of over 2750 chemicals with publicly available skin sensitisation data from 18 in vivo assays. An assay hierarchy was designed to enable the classification of chemicals within this dataset as either sensitisers or non-sensitisers where data from more than one in vivo test was available. The negative prediction approach was validated internally, using a 5-fold cross-validation, and externally, against a proprietary dataset of approximately 1000 chemicals with in vivo reference data shared by members of the pharmaceutical, nutritional, and personal care industries. The negative predictivity for this proprietary dataset was high in all cases (>75%), and the model was also able to identify structural features that resulted in a lower accuracy or a higher uncertainty in the negative prediction, termed misclassified and unclassified features respectively. These features could serve as an aid for further expert assessment of the negative in silico prediction. PMID- 29580971 TI - Retroviral Gag protein-RNA interactions: Implications for specific genomic RNA packaging and virion assembly. AB - Retroviral Gag proteins are responsible for coordinating many aspects of virion assembly. Gag possesses two distinct nucleic acid binding domains, matrix (MA) and nucleocapsid (NC). One of the critical functions of Gag is to specifically recognize, bind, and package the retroviral genomic RNA (gRNA) into assembling virions. Gag interactions with cellular RNAs have also been shown to regulate aspects of assembly. Recent results have shed light on the role of MA and NC domain interactions with nucleic acids, and how they jointly function to ensure packaging of the retroviral gRNA. Here, we will review the literature regarding RNA interactions with NC, MA, as well as overall mechanisms employed by Gag to interact with RNA. The discussion focuses on human immunodeficiency virus type-1, but other retroviruses will also be discussed. A model is presented combining all of the available data summarizing the various factors and layers of selection Gag employs to ensure specific gRNA packaging and correct virion assembly. PMID- 29580973 TI - A pre-clinical safety study of PEGylated recombinant human endostatin (M2ES) in Sprague Dawley rats. AB - PEGylated recombinant human endostatin (M2ES) exhibited prolonged serum half-life and enhanced antitumor activity when compared with endostatin. A pre-clinical study was performed to evaluate the safety of M2ES in rats. After intravenous (IV) infusions of M2ES at a dose level of 3, 15 and 75 mg/kg in Sprague Dawley (SD) rats, M2ES was well tolerated in animals, with no observable changes in clinical observation, body weight, food consumption, urine analysis, hematology and serum biochemical analysis. The increase of kidney weights, and slight to severe vacuolation and necrosis of proximal tubule epithelial cells in kidney were observed in 15 and 75 mg/kg M2ES groups, but this adverse-effect was reversible. In summary, the major toxicity target organ of M2ES might be kidney, and the no observed adverse effect level (NOAEL) of M2ES in rats was 3 mg/kg in this study. These pre-clinical safety data contribute to the initiation of the ongoing clinical study. PMID- 29580974 TI - The safety of green tea and green tea extract consumption in adults - Results of a systematic review. AB - A systematic review of published toxicology and human intervention studies was performed to characterize potential hazards associated with consumption of green tea and its preparations. A review of toxicological evidence from laboratory studies revealed the liver as the target organ and hepatotoxicity as the critical effect, which was strongly associated with certain dosing conditions (e.g. bolus dose via gavage, fasting), and positively correlated with total catechin and epigallocatechingallate (EGCG) content. A review of adverse event (AE) data from 159 human intervention studies yielded findings consistent with toxicological evidence in that a limited range of concentrated, catechin-rich green tea preparations resulted in hepatic AEs in a dose-dependent manner when ingested in large bolus doses, but not when consumed as brewed tea or extracts in beverages or as part of food. Toxico- and pharmacokinetic evidence further suggests internal dose of catechins is a key determinant in the occurrence and severity of hepatotoxicity. A safe intake level of 338 mg EGCG/day for adults was derived from toxicological and human safety data for tea preparations ingested as a solid bolus dose. An Observed Safe Level (OSL) of 704 mg EGCG/day might be considered for tea preparations in beverage form based on human AE data. PMID- 29580975 TI - Argon Cold Plasma-A Novel Tool to Treat Therapy-resistant Corneal Infections. AB - PURPOSE: To test whether therapy-resistant corneal infections can be successfully treated with argon cold plasma to reduce or eliminate pathogen microorganisms without affecting corneal cell viability. DESIGN: First-in-human case series and experimental study. METHODS: Cold plasma effects on viability of primary human corneal limbal epithelial cells were studied using exposure times from 0.5 to 10 minutes (metabolic activity, oxidative stress, apoptosis). Disinfective potential of cold plasma was tested against common pathogens (Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans) on culture medium and evaluated by counting colony-forming units and optical density measurements, as well as against S aureus in a human cornea infection model. Additionally, in a first-in-human trial 4 patients with therapy resistant corneal ulcers were treated to evaluate the clinical potential of cold plasma. RESULTS: Cells treated for 0.5-5 minutes completely recovered within 24 hours without changes in morphology; only 10-minute treatment impaired the cells permanently. No evident oxidative stress, apoptosis, or damage to the corneal structure could be found. All pathogens were susceptible to cold plasma treatments, with different levels of sensitivity. The condition of all 4 patients significantly improved after cold plasma treatment combined with antibiotic therapy. CONCLUSIONS: Our results indicate that argon cold plasma treatment reduces or eliminates common pathogens without impairing corneal epithelial cells in vitro, ex vivo, and in direct application on patients' eyes. We conclude that argon cold plasma therapy offers a potential supplement or alternative therapy for therapy-resistant corneal infections. A larger, comparative study is necessary to further confirm these findings. PMID- 29580976 TI - Inter-eye Asymmetry of Optical Coherence Tomography Angiography Vessel Density in Bilateral Glaucoma, Glaucoma Suspect, and Healthy Eyes. AB - PURPOSE: To investigate inter-eye retinal vessel density asymmetry in healthy, glaucoma suspect, and mild-to-moderate glaucoma subjects, and its potential utility for early detection of glaucomatous damage. DESIGN: Cross-sectional study. METHODS: In 153 subjects including 55 healthy, 32 glaucoma suspect, and 66 glaucoma subjects enrolled in the Diagnostic Innovations in Glaucoma Study (DIGS), vessel density was obtained from optical coherence tomography angiography (OCT-A) macular and optic nerve head scans. Thickness of peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell complex (mGCC) was measured with spectral-domain optical coherence tomography (SD-OCT) scans. Inter-eye asymmetry was calculated by taking the absolute value of difference in vessel density and thickness between the right and left eyes. RESULTS: Inter-eye retinal vessel density asymmetry parameters were significantly different among the 3 groups. Glaucoma suspects had significantly higher peripapillary and macular inter-eye vessel density asymmetries compared to healthy groups in univariate (1.1% vs 2.0%, P = .014 and 1.2% vs 2.5%, P = .027, respectively) and multivariate analyses (P = .007 and P = .038, respectively). No significant differences in asymmetry of thickness parameters were found between glaucoma suspect and healthy groups (all P > .718). However, significant differences in asymmetry of thickness parameters between glaucoma suspects and glaucoma patients (P < .01) were found for all parameters. CONCLUSION: Inter-eye vessel density asymmetry can be quantified by OCT-A measurement. Glaucoma suspects have significantly greater vessel density asymmetry than healthy eyes. Longitudinal studies are needed to better characterize the relationship of vessel density asymmetry with the development and progression of glaucoma. PMID- 29580977 TI - Difluprednate for the Treatment of Uveitic Cystoid Macular Edema. AB - PURPOSE: To describe clinical outcomes associated with the use of topical difluprednate in treating uveitic cystoid macular edema. DESIGN: Retrospective, interventional case series. METHODS: Setting: Medical record review in a tertiary care uveitis center. PATIENT POPULATION: Fifty-eight patients (72 eyes) with uveitic cystoid macular edema (CME) treated with difluprednate 0.05% ophthalmic solution between June 2012 and May 2016. MAIN OUTCOME MEASURES: Macular central subfield thickness (CST) determined by optical coherence tomography, improvement of CME (>=20% reduction in CST or resolution), and resolution of CME (CST <= 320 MUm with no cysts) at 30 days after starting treatment. Outcomes were assessed up to 90 days. RESULTS: CST on average decreased by 17% (95% CI: -33%, -7%) for eyes using only difluprednate (n = 43) and by 6% (95% CI: -17%, -2%) for eyes in patients using concomitant systemic immunosuppressive therapy (n = 29) at 30 days, a 12% difference between groups (95% CI: 2%, 21%, P = .02). Of eyes on difluprednate alone, 76% had improvement and 48% had resolution of CME. In patients using systemic therapy, 37% of eyes had improvement and 17% had resolution. Eight eyes (11%) had an intraocular pressure (IOP) > 24 mm Hg within the first 30 days. By 90 days, CME had improved in 69% of all eyes and resolved in 43% of eyes, with only 9 patients starting or increasing systemic immunosuppressive medications and 2 patients receiving periocular corticosteroid injections. CONCLUSIONS: Difluprednate was associated with an improvement in uveitic CME and could be a reasonable first-line therapy. IOP should be closely monitored. PMID- 29580978 TI - Sheep as a model for evaluating mesenchymal stem/stromal cell (MSC)-based chondral defect repair. AB - Osteoarthritis results from the degradation of articular cartilage and is one of the leading global causes of pain and immobility. Cartilage has a limited capacity for self-repair. While repair can be enhanced through surgical intervention, current methods often generate inferior fibrocartilage and repair is transient. The development of tissue engineering strategies to improve repair outcomes is an active area of research. While small animal models such as rodents and rabbits are often used in early pre-clinical work, larger animals that better recapitulate the anatomy and loading of the human joint are required for late stage preclinical evaluation. Because of their physiological similarities to humans, and low cost relative to other large animals, sheep are routinely used in orthopedic research, including cartilage repair studies. In recent years, there has been considerable research investment into the development of cartilage repair strategies that utilize mesenchymal stem/stromal cells (MSC). In contrast to autologous chondrocytes derived from biopsies of articular cartilage, MSC offer some benefits including greater expansion capacity and elimination of the risk of morbidity at the cartilage biopsy site. The disadvantages of MSC are related to the challenges of inducing and maintaining a stable chondrocyte-like cell population capable of generating hyaline cartilage. Ovine MSC (oMSC) biology and their utility in sheep cartilage repair models have not been reviewed. Herein, we review the biological properties of MSC derived from sheep tissues, and the use of these cells to study articular cartilage repair in this large animal model. PMID- 29580979 TI - Bone morphogenetic proteins for articular cartilage regeneration. AB - Degeneration of articular cartilage (AC) tissue is the most common cause of osteoarthritis (OA) and rheumatoid arthritis. Bone morphogenetic proteins (BMPs) play important roles in bone and cartilage formation. This article reviews the experimental and clinical applications of BMPs in cartilage regeneration. Experimental evidence indicates that BMPs play an important role in protection against cartilage damage caused by inflammation or trauma, by binding to different receptor combinations and, consequently, activating different intracellular signaling pathways. Loss of function of BMP-related receptors contributes to the decreased intrinsic repair capacity of damaged cartilage and, thus, the multifunctional effects of BMPs make them attractive tools for the treatment of cartilage damage in patients with degenerative diseases. However, the development of BMP therapy as a treatment modality for cartilage regeneration has been hampered by certain factors, such as the eligibility of participants in clinical trials, financial support, drug delivery carrier safety, availabilities of effective scaffolds, appropriate selection of optimal dose and timing of administration, and side effects. Further research is needed to overcome these issues for future routine clinical applications. Research and development leading to the successful application of BMPs can initiate a new era in the treatment of cartilage degenerative diseases like OA. PMID- 29580980 TI - Tumor suppressor ZHX2 restricts hepatitis B virus replication via epigenetic and non-epigenetic manners. AB - Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA), the stable genomic form as the template for viral transcription, plays a crucial role in viral persistence which remains a major global health problem. While accumulating evidence suggests the involvement of transcription factors and epigenetic machinery in cccDNA transcription, the roles of host transcription factors which contribute to epigenetic modification of cccDNA remain largely unknown. Zinc finger and homeoboxes 2 (ZHX2) is abundantly expressed in adult hepatocytes, where it acts as a transcriptional repressor and tumor suppressor by directly inhibiting the promoter activities of target genes. However, whether ZHX2 influences HBV replication or is involved in cccDNA epigenetic regulation remain unknown. In this study, we investigated the role of ZHX2 in cccDNA transcription. Analysis of immunohistochemistry showed that ZHX2 nuclear expression negatively correlated with serum HBV DNA and HBeAg. Remarkably, ZHX2 significantly decreased HBV antigens expression, pregenomic RNA (pgRNA) and HBV core particle DNA production both in vitro and in mouse livers supporting HBV antigens expression and cccDNA transcription. Dual luciferase and cccDNA ChIP assays confirmed that ZHX2 could bind to cccDNA and transcriptionally inhibit HBV promoter activities. In addition, ZHX2 suppressed the expression of histone regulator genes, such as cccDNA bound p300/CBP, and led to epigenetic repression of cccDNA. These findings highlight the roles of a novel restriction factor, ZHX2, in modulating HBV replication via regulating HBV promoter activities and cccDNA modifications. This study furthers our understanding of HBV transcription from cccDNA and offers new insights on potential HBV therapy. PMID- 29580981 TI - Improved intracellular PHA determinations with novel spectrophotometric quantification methodologies based on Sudan black dye. AB - The presence of intracellular polyhydroxyalkanoates (PHAs) is usually studied using Sudan black dye solution (SB). In a previous work it was shown that the PHA could be directly quantified using the absorbance of SB fixed by PHA granules in wet cell samples. In the present paper, the optimum SB amount and the optimum conditions to be used for SB assays were determined following an experimental design by hybrid response surface methodology and desirability-function. In addition, a new methodology was developed in which it is shown that the amount of SB fixed by PHA granules can also be determined indirectly through the absorbance of the supernatant obtained from the stained cell samples. This alternative methodology allows a faster determination of the PHA content (involving 23 and 42 min for indirect and direct determinations, respectively), and can be undertaken by means of basic laboratory equipment and reagents. The correlation between PHA content in wet cell samples and the spectra of the SB stained supernatant was determined by means of multivariate and linear regression analysis. The best calibration adjustment (R2 = 0.91, RSE: 1.56%), and the good PHA prediction obtained (RSE = 1.81%), shows that the proposed methodology constitutes a reasonably precise way for PHA content determination. Thus, this methodology could anticipate the probable results of the above mentioned direct PHA determination. Compared with the most used techniques described in the scientific literature, the combined implementation of these two methodologies seems to be one of the most economical and environmentally friendly, suitable for rapid monitoring of the intracellular PHA content. PMID- 29580982 TI - Real-time PCR-based method for rapid detection of Aspergillus niger and Aspergillus welwitschiae isolated from coffee. AB - Some species from Aspergillus section Nigri are morphologically very similar and altogether have been called A. niger aggregate. Although the species included in this group are morphologically very similar, they differ in their ability to produce mycotoxins and other metabolites and their taxonomical status has evolved continuously. Among them, A. niger and A. welwitschiae are ochratoxin A and fumonisin B2 producers and their detection and/or identification is of crucial importance for food safety. The aim of this study was the development of a real time PCR-based method for simultaneous discrimination of A. niger and A. welwitschiae from other species of the A. niger aggregate isolated from coffee beans. One primer pair and a hybridization probe specific for detection of A. niger and A. welwitschiae strains were designed based on the BenA gene sequences, and used in a Real-time PCR assay for the rapid discrimination between both these species from all others of the A. niger aggregate. The Real-time PCR assay was shown to be 100% efficient in discriminating the 73 isolates of A. niger/A. welwitschiae from the other A. niger aggregate species analyzed as a negative control. This result testifies to the use of this technique as a good tool in the rapid detection of these important toxigenic species. PMID- 29580983 TI - A comparison of ergosterol and PLFA methods for monitoring the growth of ligninolytic fungi during wheat straw solid state cultivation. AB - Ergosterol, total phospholipid fatty acid (PLFA) and linoleic acid (18:2n-6) have all been used to determine fungal growth. This paper compares these methods to assess the growth of four different saprotrophic fungal species during solid state cultivation using a wheat straw substrate that have not been compared or measured previously. Ergosterol production appeared to track the mycelia growth well but its production differed considerably between fungi. This means that a specific conversion factor needs to be determined and applied for any given fungus. In comparison, measurements of total PLFA and linoleic acid only showed promise for determining the growth of Postia placenta due to the positive correlation with ergosterol measurements. In contrast, the other fungi tested (Phanerochaete chrysosporium, Serpula lacrymans and Schizophyllum commune) showed either no correlation or in some cases a negative correlation using this assay. The novel findings highlight the variation in fungal fatty acid between species, culture conditions and durations of incubation; suggesting that measurement of linoleic acid is only usable in specific cases. These findings provide important consideration for the study of fungi growing in solid substrates and suggest that the use of PLFA might bias diversity indices. PMID- 29580984 TI - Monitoring cellular redox state under hypoxia using a fluorescent sensor based on eel fluorescent protein. AB - Genetically encoded fluorescent sensors are widely used to visualize secondary messengers, metabolites and dynamic events in living cells. However, almost all of these sensors are based on Aequorea GFPs or GFP-like proteins, which do not correctly maturate and fluoresce under hypoxia or anoxic conditions, greatly limiting their application in biomedical research. Herein, we provide a novel strategy for design of sensors and report a series of thiol redox-sensitive sensor based on a recently discovered oxygen-independent fluorescent protein UnaG from Japanese eel. These redox sensors have large dynamic range, rapid responsiveness, a flexible "switch", and pH-independence, are particularly compatible with hypoxia conditions, and therefore represent a substantial improvement for live-cell redox measurement. We further demonstrated the versatility of these redox sensors, by simultaneously monitoring redox changes and hypoxia state in living cells, thereby proving its capability as a powerful and flexible tool for indexing multidimensional metabolism data in the context of physiological stressors and pathological states. These redox sensors are not only the first case of UnaG-based functional sensors, but also the first case of functional sensors based on non GFP-like proteins. Based on this strategy, more oxygen-independent biosensors could be developed, hence, provide new opportunities for bioimaging. PMID- 29580985 TI - Tributyltin role on the serotonin and histamine receptors in human umbilical artery. AB - Some studies in animals suggest that TBT may constitute a risk factor for cardiovascular diseases. Hence, the main purpose of this study was to investigate in human umbilical artery (HUA) the effect of TBT on vascular reactivity, manly in serotonin (5-HT) and histamine receptors. Using standard organ bath techniques, rings of HUA without endothelium were contracted by 5-HT and histamine. We also investigated the effect of TBT on the expression of the receptors using Real-time PCR. The results show that TBT short term effects include concentration-dependent relaxation. Moreover, at long term exposures, the arteries treated with 100 MUM of TBT do not have contraction capacity when 5-HT is added, and the gene expression of 5-HT2A receptor decrease. Regarding histamine, it was demonstrated that TBT induces a concentration-dependent relaxation and the H1 gene expression levels decrease. In conclusion TBT modifies the activity and expression of 5-HT and histamine receptors. PMID- 29580986 TI - Maduramicin induces apoptosis in chicken myocardial cells via intrinsic and extrinsic pathways. AB - Maduramicin is one of the most extensively used anticoccidial drugs for the treatment of Eimeria spp. infections. However, overdosage, misuse and drug interactions have resulted in the development of ionophore toxic syndrome. Heart and skeletal muscles have been identified as the main target organs of toxicity. In the present study, primary chicken myocardial cells were isolated to investigate the toxicity and underlying mechanisms of maduramicin. Our results showed that maduramicin causes morphological changes and a decrease in the viability of chicken myocardial cells. Annexin V-FITC/PI and 4',6-diamidino-2 phenylindole (DAPI) staining showed a significant increase in the number of apoptotic cells. Furthermore, caspases-3/8/9 were activated at the gene and protein levels and this was accompanied by the upregulation of apoptosis-related genes, including bcl-2, bax, and cytochrome C. Treatment with the pan-caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp (O-Me) fluoromethyl ketone (z-VAD-fmk) ameliorated the apoptosis and cytotoxicity. Furthermore, intracellular Ca2+ and reactive oxygen species (ROS) were elevated, whereas mitochondrial membrane potential (MMP) and intracellular glutathione (GSH) decreased with exposure to maduramicin. The antioxidant N-acetyl-cysteine (NAC) had no significant effect on maduramicin-induced cytotoxicity and apoptosis. Taken together, our findings demonstrate that maduramicin is cytotoxic to primary chicken myocardial cells via caspase dependent and independent apoptotic pathways. PMID- 29580987 TI - Interaction of carbon monoxide-releasing ruthenium carbonyl CORM-3 with plasma fibronectin. AB - Inhaled carbon monoxide (CO) gas is highly toxic, but the human body produces low levels of CO for vasoregulation and other purposes. Given the established protective roles of low concentrations of CO gas against a panel of pathological insults, CO-releasing molecules (CORMs) have been developed and examined in disease models both in vitro and in vivo. Among CORMs, CORM-3 [Ru(CO)3Cl(glycinate)], a ruthenium carbonyl compound, has been extensively studied since it is water-soluble and is suitable for in vivo application. As one of the most prominent features of CO gas is its anti-fibrotic effect, we examined the effects of CORM-3 on mouse embryonic fibroblasts (MEFs). The application of 1 mM CORM-3 to MEFs resulted in the decreased syntheses of collagens I and III within 24 h, confirming an anti-fibrotic effect. To our surprise, CORM-3 caused a rapid (within 1 h) dissociation of cell-associated plasma fibronectin (FN) from the cells, which is associated with formation of a reduction-resistant oligomer of plasma FN. This aberrant oligomerization of plasma FN was reproduced using purified FN in vitro. Furthermore, we showed that RuCl3, but not another water soluble CORM, CORM-A1 [Na2H3BCO2], also oligomerized plasma FN in vitro. FN depletion from the serum substantially ameliorates cell death by prolonged (72 h) exposure to CORM-3, suggesting a detrimental role of FN oligomerization on cell death. Taken together, we reveal for the first time that FN is a CORM-3 interactive plasma protein, and that the CORM-3-FN interaction is involved in the death of fibroblasts. PMID- 29580988 TI - Kruppel-like factor 4 regulates keratinocyte senescence. AB - Keratinocyte replicative senescence has an important role in time-related changes of epidermis. Previous studies demonstrated that miRNAs play key roles in inhibiting proliferation and in the acquisition of the keratinocyte senescent phenotype as well as in individual ageing. Kruppel-like factor 4 is a transcription factor with dual functions in keratinocytes, being a stemness factor and a pro-differentiation factor. Interestingly, in skin squamous cell carcinomas KLF4 expression is strongly down-regulated or absent. While KLF4 involvement in senescence and ageing has not been investigated yet. Here, we show that Klf4 protein decreases during keratinocyte replicative senescence and during physiological skin aging, while its mRNA level does not change. We demonstrated that the senescence-associated miR-34a regulates post-transcriptionally Klf4 expression. KLF4 silencing is sufficient to induce a senescent phenotype in primary keratinocytes and ectopic miR-34a over-expression phenocopies this result. Our findings identify a novel regulatory loop between miR-34a and KLF4 during keratinocytes replicative senescence. This regulatory loop, beside aging, may play a role in age-related pathologies. PMID- 29580989 TI - AMP-activated protein kinase stabilizes FOXO3 in primary myotubes. AB - AMP-activated protein kinase (AMPK) is a critical enzyme in conditions of cellular energy deficit such as exercise, hypoxia or nutritional stress. AMPK is well known to regulate protein degradation pathways notably through FOXO-related axis. In this study, we investigated the implication of AMPK activation in FOXO3 expression and stability in skeletal muscle primary myotubes. First, time course and dose response studies revealed optimal AICAR treatment duration and dose in skeletal muscle cells. Then, experiments with cycloheximide treatment of primary myotubes highlighted that AICAR infusion extends FOXO3 protein half-life. Our results also showed that AICAR treatment or nutrient depletion increases FOXO3 expression in primary myotubes and the expression of the mitochondrial E3 ligase Mul1 involved in mitochondrial turnover (mitophagy). In AMPK KO cells, nutrient depletion failed to alter the level of some FOXO3-dependent atrophic genes, including LC3B, BNIP3, and the mitochondrial E3 ligase Mul1, but not the expression of other genes (i.e. FOXO1, Gabarapl1, MAFbx, MuRF1). In summary, our data highlight that AMPK stabilizes FOXO3 and suggest a role in the first initiation step of mitochondrial segregation in muscle cells. PMID- 29580990 TI - Copper induces structural changes in N-terminus of human prion protein. AB - Copper ions reportedly bind to the cellular prion (PrPC) and induce PrP proteinase K (PK) resistant from (PrPres). PrPC also plays a role in response to oxidative stress. By using purified human PrP23-98 containing octarepeats, we have found that Cu(II) induces PrPres determined by Western blots and atomic force microscopy, and structural changes detected by hydrogen/deuterium exchange in the PrP N-terminus. Therefore, we have provided the evidence that copper ions play an important role in the change of N-terminus of human prion protein. PMID- 29580991 TI - Ferritin heavy chain controls the HIF-driven hypoxic response by activating the asparaginyl hydroxylase FIH. AB - Hypoxia-inducible factor 1 (HIF-1) is a key player in cellular response to hypoxia. The stability and transcriptional activity of this protein are oxygen dependently regulated by the prolyl hydroxylases PHD1-3 and the asparaginyl hydroxylase FIH. Recently, ferritin heavy chain (FTH1) has been characterized to reinforce the HIF-1 signaling pathway in an indirect way through the inhibition of PHD activity by depleting the free iron pool in the cytoplasm. In the present study, we addressed the role of FTH1 in the FIH control of HIF-1 activity. Unexpectedly, immunoprecipitation analyses revealed that FTH1 directly interacted with FIH. In an in vitro hydroxylation assay, FTH1 was found to facilitate the FIH-mediated Asn803 hydroxylation in HIF-1alpha. As expected, FTH1 prevented the recruitment of p300 to HIF-1alpha through the Asn803 hydroxylation. In luciferase reporter analyses, FTH1 was found to repress the transcriptional activity of HIF 1alpha in HCT116 cells under either normoxic or hypoxic conditions. Consequently, FTH1 downregulated the expression of the HIF-1 target genes, such as VEGF, CA9 and GLUT1. Our results suggest a new role of FTH1 as a co-regulator for the FIH mediated oxygen sensing pathway. Since HIF-1alpha is involved in pathogenesis of diverse hypoxia-associated diseases, we propose that FTH1 be a potential target in developing new therapeutic strategies against such diseases. PMID- 29580992 TI - Comparative toxicity and contrast enhancing assessments of Gd2O3@BSA and MnO2@BSA nanoparticles for MR imaging of brain glioma. AB - The albumin-templated Gd2O3 and MnO2 nanoparticles (NPs) have been developed as a new type of magnetic resonance (MR) T1 contrast agents. However, their potential toxicity and applicability for MR imaging of brain gliomas has not been fully explored so far. In this study, we prepared Gd2O3@BSA and MnO2@BSA nanoparticles (NPs) and investigated their toxicity comprehensively and comparatively by H&E staining, blood biochemical analysis, and adverse outcome pathways testing. It is revealed that both Gd2O3@BSA and MnO2@BSA NPs are biocompatible at a rational dose level. Although the relaxivity of MnO2@BSA NPs is less than that of Gd2O3@BSA NPs, the MnO2@BSA NPs lead to a greater contrast enhancement in the brain glioma due to the controlled release of Mn ions under the acidic tumor microenvironmental conditions. These comparative toxicity and contrast enhancement data are of fundamental importance for the clinical translation of Gd2O3@BSA and MnO2@BSA NPs as MR contrast agents for brain glioma diagnosis. PMID- 29580993 TI - Genome-wide identification of circRNAs involved in tomato fruit coloration. AB - Circular RNAs (circRNAs) are an emerging class of non-coding RNAs in plants. Our aim is to identify the circRNAs with different expression levels between tomato fruits from two cultivars ('Jinling Fenyu' and 'Jinling Moyu') at two different developmental stages. Following high-throughput sequencing, 3796 circRNAs were identified, and 243 circRNAs were shared in the four samples. As compared with the fruit at mature green stage, the expression levels of 273 and 89 circRNAs were significantly altered in the fruit at turning stage from 'Jinling Fenyu' and 'Jinling Moyu', respectively. Moreover, the parental genes of the circRNAs with significantly different expression level were mainly involved in metabolic, cellular and single-organism process and played roles in catalytic activity and binding based on GO (Gene Ontology) analysis. The results suggested that circRNAs were widespread in tomato and were generated from different chromosomes and diverse genomic regions. Some circRNAs were specific in tomato fruits at different developmental stages, which enriches the number of circRNAs in plants involved in fruit coloration and ripening. This study provides the first genome wide profile of circRNAs involved in tomato fruit coloration and lays a foundation for studying the potential biological functions of circRNAs involved in fruit ripening. PMID- 29580994 TI - Modification of gum ghatti via grafting with acrylamide and analysis of its flocculation, adsorption, and biodegradation properties. AB - In this work, an environmentally friendly gum ghatti-crosslinked-polyacrylamide (Gg-cl-PAAM) hydrogel was synthesized from gum ghatti (Gg) and acrylamide (AAM) using a microwave-assisted grafting technique, and tested for use in water purification applications as an adsorbent and flocculent. The Gg-cl-PAAM was characterized using SEM, FTIR, and TGA, and displayed pH responsive swelling behavior, with maximum swelling (2117%) observed in solution with neutral pH. The flocculation characteristics of Gg-cl-PAAM were tested in clay solutions as a function of pH, temperature, and the polymer mass loading, showing that the best performance is obtained at neutral pH at 40 degrees C. The adsorption capacities of Gg-cl-PAAM for the removal different dyes such as brilliant green (BG), rhodamine B (RhB), congo red (CR), and methyl orange (MO) were tested, revealing that the adsorption of all dyes followed the Langmuir isotherm model, with qm values of 523.62mgg-1 for BG, 421.60mgg-1 for RhB, 179.09mgg-1 for CR, and 173.69mgg-1 for MO. Finally, the environmentally friendly nature of Gg-cl-PAAM was examined using the soil-burial composting method, which demonstrated 93% degradation of the Gg-cl-PAAM hydrogel within 60days.

AB - In this study, cellulose was chemically modified through the addition of the phosphorylating agent, metaphosphoric acid in order to obtain a new material (MPCel) with higher adsorptive properties than the starting material. Both materials were characterized by infrared spectroscopy, X-ray diffraction, solid state phosphorus-31 nuclear magnetic resonance spectroscopy and thermogravimetric analysis. Maximal adsorption capacity, at 45 degrees C for pure cellulose, was 90.5mgg-1, at pH=10 and contact time of 40min, with experimental isotherms better adjusted to the Langmuir model. MPCel at the same temperature conditions showed contact time of 10min, pH=10, and maximal adsorption capacity of 150.0mgg-1, being better adjusted to the Temkin model. The kinetic study of both materials followed the pseudo-second-order model. Modification successfully occurred and both adsorbents were shown able to be capable of removing the brilliant green dye, but MPCel was more efficient for purpose, when compared to the pure cellulose.

AB - Nanoparticles of starches from different botanical origin were prepared by nanoprecipitation using 0.1M hydrochloric acid as non-solvent. The morphology and the particle size were analyzed using field emission scanning electron microscopy and dynamic light scattering. The nanoparticles were spherical and their sizes vary depending on the origin and the concentration of the starch solution. Starch nanoparticles loaded with quercetin were prepared. In-vitro release studies of the quercetin from the starch nanoparticles were performed in 35% ethanol as a release medium. The starch origin affects the quercetin loading percentage, the release kinetics and the antioxidant activity of the produced nanoparticles. The starch-quercetin nanoparticles from cereal origin showed the lowest loading percentage and the lowest fraction released of quercetin in comparison with nanoparticles from tuber and legume origin. The release kinetics seem to be controlled mainly by Fickian diffusion which have been revealed fitting the release data to the Peppas-Sahlin model. PMID- 29580997 TI - Modification of chitin with high adsorption capacity for methylene blue removal. AB - Porous chitin sorbents (PChs) with different content of chitin, ranging from 0.9% to 3.5%, were prepared by gel method with CaBr2.xH2O/CH3OH solution and characterized by FT-IR, XRD and SEM. The adsorption isotherms and kinetic analysis of methylene blue (MB) onto PChs were studied. Experimental results illustrated lower crystallinity and more pores of PChs containing 3.5% chitin displayed higher adsorption capacity, the removal of MB was 79.8%. The adsorption equilibrium isotherm curve of MB onto PChs adsorbents conformed to the Freundlich equation. The PFO, PSO and Weber-Morris models were applied to fit with the adsorption kinetics. The results demonstrated the adsorption of MB might be the mass transfer of heterogeneous system and involve multiple diffusion steps. The adsorption capacity of PChs with 3.5% chitin can maintain 65% removal ratio of MB after being used six adsorption-desorption cycles. It was supposed that PChs may be a promising, cheap, environmentally friendly and efficient adsorbent for some dye wastewater treatment in the near future. PMID- 29580998 TI - A halotolerant bifunctional beta-xylosidase/alpha-l-arabinofuranosidase from Colletotrichum graminicola: Purification and biochemical characterization. AB - A beta-xylosidase from Colletotrichum graminicola (Bxcg) was purified. The enzyme showed high halotolerance, retaining about 63% of the control activity in the presence of 2.5molL-1 NaCl. The presence of NaCl has not affected the optimum reaction temperature (65 degrees C), but the optimum pH was slightly altered (from 4.5 to 5.0) at high salt concentrations. Bxcg was fully stable at 50 degrees C for 24h and over a wide pH range even in the presence of NaCl. In the absence of salt Bxcg hydrolyzed p-nitrophenyl-beta-d-xylopyranoside with maximum velocity of 348.8+/-11.5Umg-1 and high catalytic efficiency (1432.7+/-47.3Lmmol 1s-1). Bxcg revealed to be a bifunctional enzyme with both beta-xylosidase and alpha-l-arabinofuranosidase activities, and hydrolyzed xylooligosaccharides containing up to six pentose residues. The enzyme showed high synergistic effect (3.1-fold) with an endo-xylanase for the hydrolysis of beechwood xylan, either in the absence or presence of 0.5molL-1 NaCl, and was tolerant to different organic solvents and surfactants. This is the first report of a halotolerant bifunctional beta-xylosidase/alpha-l-arabinofuranosidase from C. graminicola, and the enzyme showed attractive properties for application in lignocellulose hydrolysis, particularly under high salinity and/or in the presence of residues of pretreatment steps. PMID- 29580999 TI - Highly stable single-strand-specific 3'-nuclease/nucleotidase from Legionella pneumophila. AB - The Gram-negative bacterium Legionella pneumophila is one of the known opportunistic human pathogens with a gene coding for a zinc-dependent S1-P1 type nuclease. Bacterial zinc-dependent 3'-nucleases/nucleotidases are little characterized and not fully understood, including L. pneumophila nuclease 1 (Lpn1), in contrast to many eukaryotic representatives with in-depth studies available. To help explain the principle properties and role of these enzymes in intracellular prokaryotic pathogens we have designed and optimized a heterologous expression protocol utilizing E. coli together with an efficient purification procedure, and performed detailed characterization of the enzyme. Replacement of Ni2+ ions by Zn2+ ions in affinity purification proved to be a crucial step in the production of pure and stable protein. The production protocol provides protein with high yield, purity, stability, and solubility for structure-function studies. We show that highly thermostable Lpn1 is active mainly towards RNA and ssDNA, with pH optima 7.0 and 6.0, respectively, with low activity towards dsDNA; the enzyme features pronounced substrate inhibition. Bioinformatic and experimental analysis, together with computer modeling and electrostatics calculations point to an unusually high positive charge on the enzyme surface under optimal conditions for catalysis. The results help explain the catalytic properties of Lpn1 and its substrate inhibition. PMID- 29581000 TI - Preparation and characterization of contact active antibacterial surface based on chemically modified nanofibrillated cellulose by phenanthridinium silane salt. AB - The main object of this research is chemical modification of the nanofibrillated cellulose (NFC) surface with a phenanthridinium silane salt to develop durable non-leaching antibacterial surface. Initially, (3-trimethoxysilylpropyl) phenanthridinium iodide (TMSPhI) as an antibacterial agent was synthesized using (3-chloropropyl trimethoxysilane) (CPTMS) and phenanthridine in the presence of potassium iodide. Subsequently, NFC was cationized by reaction of its hydroxyl groups with the trimethoxysilane group of TMSPhI to prepare the modified sample (NFC-TMSPhI). The synthesized TMSPhI was characterized by FT-IR, 1H and 13C NMR spectroscopies. The modified NFC samples were also characterized by FE-SEM/EDX, XRD, TGA, elemental analysis, contact angle measurement, FT-IR, UV-Visible and fluorescence spectroscopies. The obtained NFC-TMSPhI samples presented fluorescence property at the maximum emission wavelength in the range of 539-549 nm. Additionally, the antibacterial activity of the modified samples were evaluated quantitatively against Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria. All the modified samples displayed promising results with at least bacteriostatic effect or bactericidal properties. Finally, the cytotoxic effect of the modified sample on human dermal fibroblasts (HDFs) and two cancer cell lines (MCF-7 and Hela) was investigated that showed dose- and surface charge dependent toxicity. PMID- 29581001 TI - Supramolecular hydrogel formation between chitosan and hydroxypropyl beta cyclodextrin via Diels-Alder reaction and its drug delivery. AB - Chitosan-cyclodextrin hydrogel (CFCD) was prepared via Diels-Alder reaction between furfural functionalized chitosan (CF) and N-maleoyl alanine functionalized hydroxypropyl beta-cyclodextrin (HPCD-AMI) in aqueous media without any catalyst or initiator. The CF and HPCD-AMI were confirmed by Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy. The resultant CFCD hydrogel was characterized in terms of thermal peripteries, microstructure, rheology behavior, and swelling capacity. The rheology analysis found that the storage modulus G' ranged from 1pa to 1200pa as the degree of furfural substitute on chitosan increased from 2.6% to 28.3%, indicating the hydrogel strength can be tuned readily by reaction stoichiometry. The swelling behaviors proved that CFCD hydrogel was pH-responsive with low swelling capacity, which would be preferable for drug delivery. Drug adsorption analysis showed the introduction of cyclodextrin into CFCD hydrogels promoted drug adsorption capacity. In addition, methyl orange cumulative release in PBS buffer was only 48.85% after 24h, suggesting CFCD hydrogel had good sustained release capacity on the loaded drug. PMID- 29581002 TI - Design, characterization and preliminary biological evaluation of new lignin-PLA biocomposites. AB - The study focuses on the obtainment of new poly (lactic acid)-lignin biocomposites. The effect of lignin loading on the morphology and mechanical properties, as well as the water uptake behaviour of the obtained biocomposites, was investigated in order to elucidate the influence of lignin incorporation into a poly (lactic acid) matrix. The addition of 7% lignin improved the Young modulus and led to a decrease in the tensile strength in comparison with the corresponding values of the poly (lactic acid) matrix, while the water sorption capacity slowly decreased. A subsequent increment in lignin loading from 7 to 15wt% resulted in an increase in tensile strength, as well as in a decline in the water sorption capacity. These results show the importance of the lignin content in controlling the properties of such composites. Furthermore, the behaviour of the PLA-lignin biocomposites in SBF was another concern for evaluation of mechanical performance and biological activity. The mechanical performance declined after immersion in simulated body fluid, but the properties of the biomaterials remained sufficiently high for the perspective of their use in medical applications. In-vitro biocompatibility studies evidenced that the addition of lignin to a poly (lactic acid) matrix can allow tailoring the final properties of the composites without inducing any significant change in cell metabolic activity (compared to poly (lactic acid) itself). PMID- 29581003 TI - Carbazole ligands as c-myc G-quadruplex binders. AB - The interactions of c-myc G-quadruplex with three carbazole derivatives were investigated by UV-Vis spectrophotometry, fluorescence, CD spectroscopy, and molecular modeling. The results showed that a combination of carbazole scaffold functionalized with ethyl, triazole and imidazole groups resulted in stabilization of the intramolecular G-quadruplex formed by the DNA sequence derived from the NHE III1 region of c-myc oncogene (Pu22). Binding to the G quadruplex Pu22 resulted in the significant increase in fluorescence intensity of complexed ligands 1-3. All ligands were capable of interacting with G4 DNA with binding stoichiometry indicating that two ligand molecules bind to G-quadruplex with comparable affinity, which agrees with binding model of end-stacking on terminal G-tetrads. PMID- 29581004 TI - Preparation of biocompatible and biodegradable silk fibroin/chitin/silver nanoparticles 3D scaffolds as a bandage for antimicrobial wound dressing. AB - One of the most serious challenge in wound care is difficulty of the infection control in wound healing process. Wound dressings with antimicrobial effects are useful to minimize the bacterial infections of wounds. In this study a biocompatible and biodegradable silk fibroin/chitin nanocomposite scaffolds with various content of silver nanoparticles (0.001, 0.01, and 0.1%) were fabricated via freeze-drying method for successful wound dressing application. The nanocomposite scaffolds have biocompatibility with high antimicrobial effects, good mechanical properties, and high porosity. Furthermore, swelling and water uptake, blood clotting, and biodegradability were also investigated. The antimicrobial evaluation with both disc diffusion method and colony counts imply that nanocomposite scaffolds have high antimicrobial activity and could successfully inhibit the growth of E. coli, S. aureus, and C. albicans. Also proliferation, cell viability, and cell attachment with MTT assay and DAPI staining on nHFFF2 cell, have proved the cytocompatibility nature of the nanocomposite scaffolds. All results revealed that prepared nanocomposite scaffolds are good candidate for wound dressing and could be use in further in vivo uses. PMID- 29581005 TI - Influence of polysiloxane as nanofiller on the surface, optical and thermal properties of guar gum grafted polyaniline matrix. AB - Mesoporous silica containing nanocomposites of in situ polymerised aniline grafted on guar gum (GG), were synthesised by sol-gel technique. Characterization of samples with respect to SEM, TEM, XRD, XPS, FTIR, BET, UV-vis, and PL illustrated the optically active materials with diverse morphologies. Microscopic analysis rendered transitional changes from smooth GG to coated PANI grafts and dense clusters of polysiloxane nanocomposites. FTIR analysis confirmed the interaction of GG-PANI-Si components. XRD diffractograms illustrate tremendous reduction of dominant amorphous phase of GG by grafted HCl doped PANI depicted by characteristic peaks (centred at 2theta=~25 degrees and 2theta=~20.0 degrees ) in the partially crystalline and amorphous GG-g-PANI and GG-g-PANI-Si1 nanocomposites. Phase modification through PANI grafting showed specific surface area of GG-g-PANI (7.6m2/g) improving immensely with low polysiloxane contents to ~170.6m2/g in GG-g-PANI-Si1 compared to 25.6m2/g of GG-g-PANI-Si2. The nanocomposites were thermally stable up to ~240 degrees C, each leaving 69% (GG-g PANI-Si1) and ~77% (GG-g-PANI-Si2) of inorganic residues. Both showed no thermal dedoping, suggesting the good thermal protection offered by polysiloxane layer. PMID- 29581006 TI - Amino functionalization of carboxymethyl cellulose for efficient immobilization of urease. AB - Jack bean urease (EC.3.5.1.5) was effectively immobilized onto amino functionalized epichlorohydrin cross-linked carboxymethyl cellulose (ECH-CMC) beads that were fabricated by graft co-polymerization of polyacrylamide (PAm) onto ECH-CMC beads in presence of potassium persulfate (KPS)/thiourea (TU) combined redox initiator followed by Hoffmann degradation. The progress of the synthesis along with immobilization processes was investigated by FTIR spectra. Also, the morphological structures of the beads before and after urease immobilizations were examined using SEM. Immobilization efficiency and immobilized urease amounts were estimated as a function of the amino functionalization degrees. The effects of pH and temperature on urease activity were studied. The results showed that after immobilization the optimum pH and temperature displayed higher shifts to 8 and 45 degrees C, respectively, which reveal a higher structural stability upon immobilization performance. Moreover, the kinetic studies indicated that the urea hydrolysis reaction, which catalyzed by urease enzyme displayed a good fit with Michaelis-Menten equation, and the kinetic parameters Km and vm were estimated to be 14+/-0.7mM and 2+/ 0.2MUmolNH3/min.mg immobilized urease, respectively. Furthermore, the immobilized urease maintained approximately 88% of its initial activity after the 10th reuse cycle. PMID- 29581008 TI - Editorial on special issue: Machine learning on MCI. PMID- 29581007 TI - Positive autoregulation of the flhDC operon in Proteus mirabilis. AB - Using a variety of techniques, we demonstrate the Class I regulator of the flagellar cascade, FlhD4C2, can activate its own expression in Proteus mirabilis. This activation was direct, as the FlhD4C2 protein specifically bound to its promoter region. The expression of bacterial genes under a positive feedback control can exhibit varying levels between cells due to stochastic fluctuations that activate the feedback loop and result in some cells in an "ON" state. Cells containing a chromosomal flhDC::gfp transcriptional fusion exhibited a heterogeneous pattern of expression within the population during growth on agar surfaces and the percentage of cells expressing GFP increased as cells approached swarmer cell differentiation. Disrupting the FlhD4C2 -mediated positive feedback loop significantly reduced the frequency of cells exhibiting GFP expression. PMID- 29581009 TI - The Virtual Shop: A new immersive virtual reality environment and scenario for the assessment of everyday memory. AB - BACKGROUND: Assessing and predicting memory performance in everyday life is a common assignment for neuropsychologists. However, most traditional neuropsychological tasks are not conceived to capture everyday memory performance. NEW METHOD: The Virtual Shop is a fully immersive task developed to assess memory in a more ecological way than traditional neuropsychological assessments. Two studies were undertaken to assess the feasibility of the Virtual Shop and to appraise its ecological and construct validity. In study 1, 20 younger and 19 older adults completed the Virtual Shop task to evaluate its level of difficulty and the way the participants interacted with the VR material. The construct validity was examined with the contrasted-group method, by comparing the performance of younger and older adults. In study 2, 35 individuals with subjective cognitive decline completed the Virtual Shop task. Performance was correlated with an existing questionnaire evaluating everyday memory in order to appraise its ecological validity. To add further support to its construct validity, performance was correlated with traditional episodic memory and executive tasks. RESULTS: All participants successfully completed the Virtual Shop. The task had an appropriate level of difficulty that helped differentiate younger and older adults, supporting the feasibility and construct validity of the task. COMPARISON WITH EXISTING METHOD(S): The performance on the Virtual Shop was significantly and moderately correlated with the performance on the questionnaire and on the traditional memory and executive tasks. CONCLUSIONS: Results support the feasibility and both the ecological and construct validity of the Virtual Shop. PMID- 29581010 TI - Molecular cloning, expression, and characterization of UDP N-acetyl-alpha-d galactosamine: Polypeptide N-acetylgalactosaminyltransferase 4 from Cryptosporidium parvum. AB - Cryptosporidium spp. are the causative agents of diarrheal disease worldwide, but effective treatments are lacking. Cryptosporidium employs mucin-like glycoproteins with O-glycans to attach to and infect host intestinal epithelial cells. The Tn antigen (GalNAcalpha1-Ser/Thr) is an O-glycan essential for these processes, as Tn-specific lectins and a Tn-specific monoclonal antibody block attachment to and infection of host cells in vitro. The enzymes in Cryptosporidium catalyzing their synthesis, however, have not been studied. Previously, we identified four genes encoding putative UDP N-acetyl-alpha-d galactosamine:polypeptide N-acetylgalactosaminyltransferases (ppGalNAc-Ts) in the genomes of three Cryptosporidium spp. Here we report the in silico analysis, cloning, expression, purification, and characterization of one of the four enzymes Cryptosporidium parvum (Cp)-ppGalNAc-T4. This enzyme contains the characteristic domains and motifs conserved in ppGalNAc-Ts and is expressed at multiple time points during in vitro infection. Recombinant soluble Cp-ppGalNAc T4 was enzymatically active against an unmodified EA2 peptide suggesting that it may function as an "initiating" ppGalNAc-T. Cp-ppGalNAc-T4 also exhibited a strong preference for UDP-GalNAc over other nucleotide sugar donors and was active against unmodified and O-glycosylated versions of the C. parvum gp40 derived peptide, with a preference for the former, suggesting it may play a role in modifying this glycoprotein in vivo. Given the importance of mucin-type O glycosylation in Cryptosporidium spp., the enzymes that catalyze their synthesis may serve as potential therapeutic targets. PMID- 29581011 TI - A plant-like mitochondrial carrier family protein facilitates mitochondrial transport of di- and tricarboxylates in Trypanosoma brucei. AB - The procyclic form of the human parasite Trypanosoma brucei harbors one single, large mitochondrion containing all tricarboxylic acid (TCA) cycle enzymes and respiratory chain complexes present also in higher eukaryotes. Metabolite exchange among subcellular compartments such as the cytoplasm, the mitochondrion, and the peroxisomes is crucial for redox homeostasis and for metabolic pathways whose enzymes are dispersed among different organelles. In higher eukaryotes, mitochondrial carrier family (MCF) proteins transport TCA-cycle intermediates across the inner mitochondrial membrane. Previously, we identified several MCF members that are essential for T. brucei survival. Among these, only one MCF protein, TbMCP12, potentially could transport dicarboxylates and tricarboxylates. Here, we conducted phylogenetic and sequence analyses and functionally characterised TbMCP12 in vivo. Our results suggested that similarly to its homologues in plants, TbMCP12 transports both dicarboxylates and tricarboxylates across the mitochondrial inner membrane. Deleting this carrier in T. brucei was not lethal, while its overexpression was deleterious. Our results suggest that the intracellular abundance of TbMCP12 is an important regulatory element for the NADPH balance and mitochondrial ATP-production. PMID- 29581012 TI - The pseudo-dimeric tyrosyl-tRNA synthetase of T. brucei aminoacylates cytosolic and mitochondrial tRNATyr and requires both monomeric units for activity. AB - Aminoacyl-tRNA synthetases are essential for protein synthesis. The single-copy tyrosyl-tRNA synthetase (Tb-TyrRS) of T. brucei has an unusual structure and forms a pseudo-dimer. It is therefore twice the size than tyrosyl-tRNA synthetases of most other organisms. Here we show by inducible RNAi that Tb-TyrRS is essential for normal growth of procyclic T. brucei. Furthermore we demonstrate that Tb-TyrRS aminoacylates cytosolic as well as mitochondrial tRNATyr indicating that it is dually localized. Finally we show that individual deletion of the 36 N or C-terminal amino acids abolishes the function of Tb-TyrRS. This indicates that both monomeric units of the enzyme, the C-terminal one of which is predicted to lack enzymatic activity, are essential for Tb-TyrRS function. In summary our results together with previous studies support the notion that Tb-TyrRS might be a suitable drug target. PMID- 29581013 TI - Industry Financial Relationships in Neurosurgery in 2015: Analysis of the Sunshine Act Open Payments Database. AB - OBJECTIVE: The 2013 Physician Payments Sunshine Act mandates that all U.S. drug and device manufacturers disclose payments to physicians. All payments are made available annually in the Open Payments Database (OPD). Our aim was to determine prevalence, magnitude, and nature of these payments to physicians performing neurologic surgery in 2015 and to discuss the role that financial conflicts of interest play in neurosurgery. METHODS: All records of industry financial relationships with physicians identified by the neurological surgery taxonomy code in 2015 were accessed via the OPD. Data were analyzed in terms of type and amounts of payments, companies making payments, and comparison with previous studies. RESULTS: In 2015, 83,690 payments (totaling $99,048,607) were made to 7613 physicians by 330 companies. Of these, 0.01% were >$1 million, and 73.2% were <$100. The mean payment ($13,010) was substantially greater than the median ($114). Royalties and licensing accounted for the largest monetary value of payments (74.2%) but only 1.7% of the total number. Food and beverage payments were the most commonly reported transaction (75%) but accounted for only 2.5% of total reported monetary value. Neurologic surgery had the second highest average total payment per physician of any specialty. CONCLUSIONS: The neurological surgery specialty receives substantial annual payments from industry in the United States. The overall value is driven by a small number of payments of high monetary value. The OPD provides a unique opportunity for increased transparency in industry-physician relationships facilitating disclosure of financial conflicts of interest. PMID- 29581014 TI - Magnetic Resonance Neurography in Chronic Lumbosacral and Pelvic Pain: Diagnostic and Management Impact-Institutional Audit. AB - BACKGROUND/OBJECTIVE: Low back and pelvic pain are among the most prevalent conditions worldwide, with major social and economic costs. The aim of this study was to evaluate the role of magnetic resonance neurography (MRN) of lumbosacral plexus in the management and outcomes of these patients with chronic pain. METHODS: Consecutive patients with chronic lumbosacral and pelvic pain referred for MRN over a year were included. Preimaging and postimaging clinical diagnosis and treatment, pain levels, and location were recorded. Pain-free survival was compared between treatments using a Cox proportional hazards model. RESULTS: A total of 202 patients with mean age 53.7 +/- 14.8 years and a male/female ratio of 1:1.53 were included. Of these patients, 115 presented with radiculopathy (57%), 56 with pelvic pain (28%), and 31 with groin pain (15%). Mean initial pain level was 6.9 +/- 1.9. Mean symptom duration was 4.21 +/- 5.86 years. Of these patients, 143 (71%) had a change in management because of MRN. After MRN, reduction in pain levels was observed in 21 of 32 patients receiving conservative treatment (66%), 42 of 67 receiving injections (63%), and 27 of 33 receiving surgery (82%). Follow-ups were available in 131 patients. Median pain-free survival was 12 months. Patients treated with surgery had significantly lower pain recurrence than patients receiving other treatments in the same time frame (hazard ratio, 3.6; 95% confidence interval, 1.4-9.2; P = 0.0061). CONCLUSIONS: MRN use in chronic lumbosacral and pelvic pain led to a meaningful change in diagnosis and treatment. After MRN, conservative treatment and injections provided pain relief; however, patients benefited more from surgery than from any other treatment. PMID- 29581015 TI - Suprasellar Hemangioblastoma with Reversible Edema-Like Change Along the Optic Tract: A Case Report and Literature Review. AB - BACKGROUND: Hemangioblastomas usually occur in the cerebellum and are often a component of von Hippel-Lindau disease. Edema-like changes along the optic tract are commonly observed in association with tumors in the sellar and suprasellar regions, such as craniopharyngiomas and pituitary adenomas. Here, we describe a case of sporadic suprasellar hemangioblastoma with edema-like changes along the optic tract that completely resolved after surgery. CASE DESCRIPTION: The patient was a 28-year-old woman with failing vision and a bitemporal hemianopia. Magnetic resonance imaging revealed a tumor accompanied by a 10-mm cyst. Fluid-attenuated inversion recovery axial magnetic resonance imaging revealed a hyperintense region along the optic tract. Other regions of the central nervous system were normal. Endoscopic transsphenoidal surgery was performed, and the histopathologic findings confirmed hemangioblastoma. Six months after surgery, the edema-like change along the optic tract had disappeared. The patient is doing well without pituitary insufficiency, pituitary hormone medications, or signs of tumor recurrence. In addition, the genetic test was negative for von Hippel-Lindau mutations. CONCLUSIONS: When examining a patient with suprasellar tumor, clinicians must consider the possibility of hemangioblastoma. Adequate treatment can improve the edematous change and visual disturbance. PMID- 29581016 TI - CASP8, XRCC1, WRN, NF2, and BRIP1 Polymorphisms Analysis Shows Their Genetic Susceptibility for Meningioma Risk and the Association with Tumor-Related Phenotype in a Chinese Population. AB - OBJECTIVE: To investigate 10 candidate single nucleotide polymorphisms (SNPs) in 5 genes (CASP8, XRCC1, WRN, NF2, and BRIP1) to confirm the association between the 5 genes and the meningioma risk in a Chinese population. METHODS: We examined 10 candidate SNPs in 5 genes (CASP8, XRCC1, WRN, NF2, and BRIP1) to confirm the association between the 5 genes and the meningioma risk and tumor-related phenotype in 433 individuals, including 215 patients with meningioma and 218 controls. RESULTS: The polymorphisms rs4968451T>G in BRIP1 were significantly associated with the risk of meningioma (TT vs. TG vs. GG additive, P = 0.005; TT+TG vs. GG dominant, P = 0.015; TT/GT+GG recessive, P = 0.034). The significant association was found only in females for BRIP1 rs4968451T>G (TT+TG vs. GG dominant, P = 0.001; TT/GT+GG recessive, P = 0.044). We observed no significant association between genotypes and the meningioma risk for the other 9 SNPs. Through genotype-phenotype analysis, the genotype of BRIP1 rs4968451T>G was also strongly associated with tumor-related phenotypes, including the tumor grade and tumor subtypes. BRIP1 rs4968451T>G was associated with markedly grade I meningioma risk (TT+TG vs. GG dominant, P = 0.008; TT/GT+GG recessive, P = 0.020). In addition, BRIP1 rs4968451T>G was associated with markedly meningothelial and transitional meningioma risk. Furthermore, the genotype of CAPS8, XRCC1, and NF2 was associated with different subtype of meningioma risk. CONCLUSIONS: This study indicated a role for BRIP1 gene variations in meningioma and may be informative for future genetic or biological studies of meningioma. These findings will assist in further understanding the genetic cause for meningiomas and guide more effective biological interventions to facilitate meningiomas. PMID- 29581017 TI - Transforaminal Endoscopic Decompression for Lumbar Spinal Stenosis: A Novel Surgical Technique and Clinical Outcomes. AB - OBJECTIVE: Transforaminal endoscopic treatment has been reported to be an effective treatment option in patients with lumbar disc herniation. However, it is rarely performed for spinal stenosis because of the limitation of endoscopic working mobility caused by the exiting nerve root and foraminous bony structure. The objective of this study was to describe a novel transforaminal endoscopic decompression technique for spinal stenosis and report the clinical results. METHODS: From October 2015 to October 2016, 30 consecutive cases were diagnosed as lateral recess stenosis in our institution and underwent transforaminal endoscopic decompression. Visual analog scale (VAS) of back and leg pain and the Oswestry Disability Index (ODI) were measured preoperatively and at follow-up. RESULTS: The mean +/- SD value of preoperative VAS leg pain score was 7.6 +/- 1.17. The score improved to 2.2 +/- 1.11 at 1 week postoperatively, 1.73 +/- 0.96 at 4 weeks postoperatively, and 1.63 +/- 0.95 at 26 weeks postoperatively (P < 0.01). The mean +/- SD value of the preoperative ODI score was 65.69 +/- 14.22. The score improved to 24.29 +/- 11.89 at 1 week postoperatively, 21.25 +/- 9.25 at 4 weeks postoperatively, and 15.62 +/- 10.49 at 26 weeks postoperatively (P < 0.01). There were no patients with postoperative infection, dural tear, delayed neurologic deterioration, or conversion to open surgery. CONCLUSIONS: Transforaminal endoscopic decompression under local anesthesia could be an effective treatment method for the selected group of patients with spinal stenosis. PMID- 29581018 TI - Application of Morphometrics as a Predictor for Survival in Patients with Prostate Cancer Metastasis to the Spine. AB - BACKGROUND: Surgery for spinal metastases can improve survival but has high morbidity that can potentially diminish benefits. New objective methods of predicting overall survival would be beneficial for surgical decision making. Morphometrics quantifies patient frailty and has been successfully used to predict overall survival in patients with lung cancer spinal metastases. This study evaluated whether morphometrics can predict survival in patients with prostate cancer spinal metastases. METHODS: Using a retrospective registry of patients with spinal metastases who underwent stereotactic body radiation therapy, we identified patients with primary prostate cancer. Morphometric measurements of the psoas muscle were taken from most recent lumbar spine computed tomography. Patients were stratified into lowest, middle, and highest tertiles based on psoas muscle area. Primary outcome measure was overall survival from the date of computed tomography scan. RESULTS: We identified 92 patients. Median survival for all patients was 124 days (95% confidence interval, 98-197 days). Patients in the smallest third for average psoas size had significantly shorter survival compared with patients in the largest third: 117 days versus 302 days (hazard ratio 2.42; 95% confidence interval, 1.32-4.43; P = 0.004). Patients in the middle third for average psoas size also had shorter survival compared with patients in the largest third: 113 days versus 302 days (hazard ratio 2.31; 95% confidence interval, 1.25-4.25; P = 0.007). CONCLUSIONS: In patients with prostate cancer spinal metastases, morphometric analysis of psoas muscle size can identify patients at risk for shorter survival. This technique can aid in surgical decision making by weighing expected survival and fitness versus potential morbidity of intervention.

AB - OBJECTIVE: To investigate the changes of Apo-J and Omi/HtrA2 protein expression in rats with intracerebral hemorrhage. METHODS: 150 Sprague-Dawley adult rats were randomly divided into 3 groups: (1) normal control (NC) group, (2) sham group, and (3) intracerebral hemorrhage (ICH) group. The data were collected at 6 hours, 12 hours, 1 day, 2 days, 3 days, 5 days, and 7 days. Apoptosis was measured by terminal deoxynucleotidyl transferase-mediated biotinylated-dUTP nick end labeling staining. The distributions of the Apo-J and Omi/HtrA2 proteins were determined by immunohistochemical staining. The levels of Apo-J mRNA and Omi/HtrA2 mRNA expressions were examined by real-time polymerase chain reaction. RESULTS: Apoptosis in the ICH group was higher than in the sham and NC groups (P < 0.05). Both the Apo-J and Omi/HtrA2 expression levels were increased in the peripheral region of hemorrhage, with a peak at 3 days. The Apo-J mRNA level positively correlated with the HtrA2 mRNA level in the ICH group (r = 0.883, P < 0.001). CONCLUSION: The expressions of Apo-J and Omi/HtrA2 increased in parallel in the peripheral region of rat cerebral hemorrhage. Local high expression of Apo J in the peripheral regions may play a neuroprotective role by inhibiting apoptosis via the Omi/HtrA2 pathway after hemorrhage. PMID- 29581020 TI - Results of Percutaneous Balloon Compression in Trigeminal Pain Syndromes. AB - OBJECTIVE: To investigate initial pain relief and subsequent recurrence after percutaneous balloon compression (PBC) and describe its association with the nature of trigeminal pain, previous procedures, or other clinical factors. METHODS: A total of 222 patients with medically refractory trigeminal pain treated with PBC at Mayo Clinic Florida between 1998 and 2017 were enrolled into this study. Patients were divided into those with typical trigeminal neuralgia (TN) and those with atypical trigeminal pain. The postprocedural rate of pain recurrence and associations between patient characteristics and recurrence were studied. RESULTS: One hundred fifty-two patients had TN and 70 patients had atypical pain. At the last follow-up, 158 patients had excellent pain relief, 37 had good pain relief, 11 had fair pain relief, and 16 had poor pain relief. The median duration of follow-up was 31.1 months. Patients with atypical pain were less likely to have an excellent result compared with patients with typical pain (61.4% vs. 82.9%; P < 0.001). Recurrence was observed in 103 patients (46.4%) and was associated with previous procedures (hazard ratio, 1.658; 95% confidence interval, 1.09-2.49; P = 0.017). Other clinical factors were not significant. CONCLUSIONS: Our study demonstrates the safety and efficacy of PBC, with 88% of patients pain-free at last follow-up. Patients with atypical pain have worse outcomes, and patients with previous procedures have a higher risk of recurrence. Repeat surgery does not decrease efficacy. We recommend conservative parameter selection at the initial procedure. PMID- 29581021 TI - Magnetic Resonance Imaging Characteristics of Pituitary Abscess: A Review of 51 Cases. AB - OBJECTIVE: To investigate pituitary abscess (PA) magnetic resonance imaging (MRI) features to improve the neuroradiologic and diagnostic knowledge of this rare disease and guide follow-up treatments. METHODS: Clinical data were collected for 51 patients with PA, and MRI data were quantitatively reviewed in a retrospective analysis. Clinical factors were analyzed to investigate their relevance. RESULTS: PA neuroimaging showed special radiologic features, including hypointensity or isointensity on T1-weighted imaging (30 patients, 58.8%), isointensity or hyperintensity on T2-weighted imaging (39 patients, 76.5%), and disappearance of the posterior pituitary bright spot in most patients (44 patients, 86.3%). After gadolinium injection, rim or rimlike enhancement was observed in 82.4% of patients (n = 42). Half of those patients showed typical rim enhancement (profound peripheral enhancement with internal hypointensity); others showed atypical rim enhancement with special signs, such as enhanced, thick abscess wall and hyperintense flocculent or cottonlike foci within the internal hypointense region. Almost all patients (96.1%) presented at least 1 sign of adjacent anatomic structure invasion, including peripheral meninges enhancement, pituitary stalk thickening, and paranasal sinus mucosa enhancement. Rank correlation analysis of the clinical time course and MRI characteristics of PA showed a Spearman correlation coefficient of 0.270, indicating borderline significance (P = 0.055). CONCLUSIONS: Classic MRI characteristics of PA show T1 signal hypointensity or isointensity, T2 signal isointensity or hyperintensity, and peripheral rim enhancement after gadolinium injection. The MRI appearance of PA may reflect the abscess liquefaction and formation. Despite its profound significance for differential diagnosis, adjacent structure invasion is generally ignored by clinicians. PMID- 29581023 TI - Stress-induced flexibility and individuality in female and male zebra finch distance calls. AB - Vocal recognition is central to the coordination and organization of behavior in pair-bonding species such as zebra finches. Zebra finches' vocalizations are individualized and support acoustic discrimination processes. Physiological states - such as the ones involved in emotional stress - can modify vocal production and consequently the structure of vocalizations. These modifications might signal the state of the caller but also impair individual recognition processes. This may represent a signaling trade-off, especially in contexts where both pieces of information can be critically important, for example when mates use calls to reunite after social isolation. Here we study the impact of a stress on the individual vocal signature in both female and male zebra finch distance calls. We built a manually curated database of distance calls of several individuals (both females and males) recorded in control and stress conditions. The stress was induced either by social isolation of the bird or using exogenous corticosterone. We developed a machine learning approach to assess the impact of stress on the individual characterization of calls. We show that while calls' spectral structure is significantly modified by stress, it still allows for the correct classification of calls to the caller. Moreover, we also show that the stress-induced modification of calls' structure is not a 'general feature signal' that can be detected as a 'stress' signal regardless of identity. Thus, female and male zebra finch calls' structure show stress-induced flexibility that stays within the range of individual vocal signatures. PMID- 29581022 TI - Neuroendoscopic Cylinder Surgery and 5-Aminolevulinic Acid Photodynamic Diagnosis of Deep-Seated Intracranial Lesions. AB - BACKGROUND: Microscopic detection of intracranial brain tumors with 5 aminolevulinic acid (5-ALA) has proven extremely useful, and reports the use of 5 ALA have recently increased. However, few reports have described 5-ALA photodynamic diagnosis (PDD) using a neuroendoscope. We performed neuroendoscopic 5-ALA PDD for various brain lesions and present a procedure using only a neuroendoscope. METHODS: We describe the diagnosis of 20 intracranial brain lesion cases with a 5-ALA-guided fluorescence endoscope. A light-emitting diode that emitted either white light or 400- to 410-nm violet light was attached to a neuroendoscope. We performed cylinder surgery with a transparent sheath under observation with a rigid neuroendoscope. RESULTS: Neuroendoscopic biopsies were performed in 11 patients, and resections were performed in 9 patients. All lesions were observed with a neuroendoscope under sequential white light and violet light. We confirmed the presence of a red fluorescent lesion under violet light in 15 patients, including 4 of 5 glioblastoma cases (80%); 1 of 2 anaplastic astrocytoma cases (50%); 4 of 5 diffuse large B cell lymphoma cases (80%); 2 of 2 metastatic brain tumors; 1 of 1 case each of diffuse astrocytoma, pilocytic astrocytoma, inflammatory change, and germinoma (100%); and no cases of anaplastic ependymoma or cysticercosis. Pretargeted lesions were accurately harvested from all biopsy specimens. Gross total resection was achieved in 5 of 9 patients using a resection procedure. CONCLUSIONS: Our described method offers a promising technique for achieving precise brain tumor biopsies and safe resection. PMID- 29581024 TI - Zoon politikon: The evolutionary origins of human socio-political systems. AB - We deploy the most up-to-date evidence available in various behavioral fields in support of the following hypothesis: The emergence of bipedalism and cooperative breeding in the hominin line, together with environmental developments that made a diet of meat from large animals adaptive, as well as cultural innovations in the form of fire, cooking, and lethal weapons, created a niche for hominins in which there was a significant advantage to individuals with the ability to communicate and persuade in a moral context. These forces added a unique political dimension to human social life which, through gene-culture coevolution, became Homo ludens-Man, the game player-with the power to conserve and transform the social order. Homo sapiens became, in the words of Aristotle's Nicomachean Ethics, a zoon politikon. PMID- 29581025 TI - Effect of the exploratory behaviour on a bird's ability to categorize a predator. AB - Despite the encountering of a predator always being extremely threatening, there is a significant plasticity among individuals in how they cope with such a situation. In laboratory experiments with wild-caught great tits (Parus major), we tested the effect of exploratory behaviour (performance in novel food, object and environment test, startle test) on the ability of individual birds to assess the threat represented by a predator. We presented a wooden dummy of the European sparrowhawk (Accipiter nisus), an extremely dangerous predator, and its visual modifications (chimeras), changing the beak or head to be non-threatening (those of a pigeon - Columba livia f. domestica). We showed that the differences between 'slow' and 'fast explorers' are not very distinct, but that 'slow explorers' generally tended to be more cautious in the presence of an unmodified sparrowhawk dummy, while the 'fast explorers' tended to observe the dummy. On the contrary, 'slow explorers' tended to treat both chimaeras (and the pigeon dummy as well) as less-threatening than 'fast explorers'. Since 'slow explorers' are usually considered to be more sensitive to environmental cues, it came as no surprise that most of them correctly assessed the unmodified sparrowhawk dummy as threatening, while they probably subjected the chimeras to a detailed inspection and were not confused by the presence of sparrowhawk features and assessed them as non-threatening. PMID- 29581026 TI - Description and phylogeny of the mitochondrial genome of Sabethes chloropterus, Sabethes glaucodaemon and Sabethes belisarioi (Diptera: Culicidae). AB - Mosquitoes as Sabethes chloropterus, Sabethes glaucodaemon, Sabethes belisarioi are species of medical and epidemiological importance for arboviruses transmission such as yellow fever and St. Louis encephalitis. Despite this, no information about these three species mitochondrial DNA has been found in literature. Our study presents a mitochondrial genome description, including identity, SNPs, mutation rate, and phylogeny analysis using COX1, COX2, NADH4, NADH5, CYOB genes. The Sa. chloropterus, Sa. glaucodaemon and Sa. belisaroi mitochondrial genome sizes 15.609 bp, 15.620 bp, 15.907 bp, respectively, with 37 functional genes, presenting about 4.982 single nucleotide polymorphisms and 13.291 identical sites between them, besides all genes with dN/dS < 1 ratio, and also a greater approximation between Sa. glaucodaemon and Sa. chloropterus than with Sa. belisarioi. Due to the importance of mitochondrial DNA for population structure studies, evolution, and others, we expect that this data can contribute to other studies related to these mosquitoes and their viruses. PMID- 29581027 TI - Improved reactive nanoparticles to treat dentin hypersensitivity. AB - : The aim of this study was to evaluate the effectiveness of different nanoparticles-based solutions for dentin permeability reduction and to determine the viscoelastic performance of cervical dentin after their application. Four experimental nanoparticle solutions based on zinc, calcium or doxycycline-loaded polymeric nanoparticles (NPs) were applied on citric acid etched dentin, to facilitate the occlusion and the reduction of the fluid flow at the dentinal tubules. After 24 h and 7 d of storage, cervical dentin was evaluated for fluid filtration. Field emission scanning electron microscopy, energy dispersive analysis, AFM and Nano-DMA analysis were also performed. Complex, storage, loss modulus and tan delta (delta) were assessed. Doxycycline-loaded NPs impaired tubule occlusion and fluid flow reduction trough dentin. Tubules were 100% occluded in dentin treated with calcium-loaded NPs or zinc-loaded NPs, analyzed at 7 d. Dentin treated with both zinc-NPs and calcium-NPs attained the highest reduction of dentinal fluid flow. Moreover, when treating dentin with zinc-NPs, complex modulus values attained at intertubular and peritubular dentin were higher than those obtained after applying calcium-NPs. Zinc-NPs are then supposed to fasten active dentin remodeling, with increased maturity and high mechanical properties. Zinc-based nanoparticles are then proposed for effective dentin remineralization and tubular occlusion. Further research to finally prove for clinical benefits in patients with dentin hypersensitivity using Zn-doped nanoparticles is encouraged. STATEMENT OF SIGNIFICANCE: Erosion from acids provokes dentin hypersensitivity (DH) which presents with intense pain of short duration. Open dentinal tubules and demineralization favor DH. Nanogels based on Ca-nanoparticles and Zn-nanoparticles produced an efficient reduction of fluid flow. Dentinal tubules were filled by precipitation of induced calcium-phosphate deposits. When treating dentin with Zn-nanoparticles, complex modulus values attained at intertubular and peritubular dentin were higher than those obtained after applying Ca-nanoparticles. Zn-nanoparticles are then supposed to fasten active dentin remodeling, with increased maturity and high mechanical properties. Zinc-based nanogels are, therefore, proposed for effective dentin remineralization and tubular occlusion. Further research to finally prove for clinical benefits in patients with dentin hypersensitivity using Zn-doped nanogels is encouraged. PMID- 29581028 TI - Nanoemulsions containing Cymbopogon flexuosus essential oil: Development, characterization, stability study and evaluation of antimicrobial and antibiofilm activities. AB - The increase of microbial resistance generates the search for new substances with antimicrobial potential. The essential oil of Cymbopogon flexuosus (Lemongrass) stands out in the literature for its antimicrobial, insecticide and antioxidant properties, but it has high volatilization and low stability, and the nanoencapsulation of this oil could be an alternative to overcome these limitations. Thus, the objective of this study was to develop, for the first time, nanoemulsions containing the essential oil of C. flexuosus, through a method that does not use organic solvent and with temperature control to avoid the volatilization of the oil, characterize and evaluate of stability and the antimicrobial and antibiofilm activities of these nanoemulsions. Nanoemulsions presented adequate physicochemical characteristics (average size less than 200 nm, polydispersity index less than 0.3, negative zeta potential and acid pH) which were maintained during 90 days of storage, and the nanoencapsulation of the C. flexuosus oil enhanced its therapeutic efficacy against the microorganisms evaluated in this study compared to the free oil. These results are very promising because among the microorganisms that the nanoemulsion containing C. flexuosus was able to inhibit the formation of biofilm are the bacteria Pseudomonas aeruginosa and Staphylococcus aureus, which were recently listed by the World Health Organization as priority pathogens for development of new antibiotics. PMID- 29581029 TI - Identification of first-stage dorsal-spined lungworm larvae of Tunisian barbary red deer: First report of Varestrongylus sagittatus and Elaphostrongylus cervi in Africa. AB - Barbary red deer (Cervus elaphus barbarus) is a protected rare subspecies of red deer. The study of its Protostrongylidae fauna based only on sporadic necropsy of naturally dead animals is difficult. Therefore diagnosis of lungworms rely mainly on the identification of the first stage larvae (L1). The L1 of the different species are not readily diagnosed on morphological basis since much variation is recorded within and among dorsal-spined larvae belonging to various species. The aim of this study was to identify the dorsal-spined lungworm larvae of the Barbary red deer. A discriminant function was established, using the measurements of L1 lungworms recorded from red deer in the literature, then applied to identify 220 dorsal-spined larvae extracted from 25 Tunisian Barbary red deer fresh fecal samples. Also the ITS2 region of rDNA of four pools of larvae (n = 25 60) were amplified, sequenced and analyzed. Using discriminant analysis of morphological traits, Elaphostrongylus cervi and Varestongylus sagittatus were identified. Molecular identification confirmed the presence of E. cervi which is the most prevalent species. This study represents the first identification of V. sagittatus and E. cervi in North Africa. PMID- 29581030 TI - Detection of Neospora caninum DNA by polymerase chain reaction in bats from Southern China. AB - Neospora caninum is an intracellular protozoan that infects many domestic and wild animals. Domestic dogs and other canids function as definitive hosts, while other mammals serve as natural intermediate hosts. In the present study, the brain tissues of bats collected in Yunnan Province, Southern China were tested by N. caninum specific-nested PCR, targeting the Nc-5 gene and the internal transcribed spacer 1 (ITS1) region of the ribosomal DNA to determine whether bats could be infected with N. caninum. N. caninum DNA was detected in 1.8% (4/227) of bats, i.e., 1.7% (1/60) in Rousettus leschenaultia, 1.7% (1/58) in Hipposideros pomona, 2.9% (2/69) in Rhinolophus pusillus, and none (0/40) in Myotis daubentoniid. The findings of the present study are only the first indication that bats could serve as an intermediate host, and further studies are necessary to confirm whether bats are involved in the transmission of N. caninum infections. PMID- 29581031 TI - IL-7-induced phosphorylation of the adaptor Crk-like and other targets. AB - IL-7 is required for T cell differentiation and mature T cell homeostasis and promotes pro-B cell proliferation and survival. Tyrosine phosphorylation plays a central role in IL-7 signaling. We identified by two-dimensional electrophoresis followed by anti-phosphotyrosine immunoblotting and mass spectrometry sixteen tyrosine phosphorylated proteins from the IL-7-dependent cell line D1. IL-7 stimulation induced the phosphorylation of the proteins STI1, ATIC and hnRNPH, involved in pathways related to survival, proliferation and gene expression, respectively, and increased the phosphorylation of CrkL, a member of a family of adaptors including the highly homologous Crk isoforms CrkII and CrkI, important in multiple signaling pathways. We observed an increased phosphorylation of CrkL in murine pro-B cells and in murine and human T cells. In addition, IL-7 increased the association of CrkL with the transcription factor Stat5, essential for IL-7 pro-survival activity. The selective tyrosine kinase inhibitor Imatinib. counteracted the IL-7 pro-survival effect in D1 cells and decreased CrkL phosphorylation. These data suggested that CrkL could play a pro-survival role in IL-7-mediated signaling. We observed that pro-B cells also expressed, in addition to CrkL, the Crk isoforms CrkII and CrkI and therefore utilized pro-B cells conditionally deficient in all three to evaluate the role of these proteins. The observation that the IL-7 pro-survival effect was reduced in Crk/CrkL conditionally-deficient pro-B cells further pointed to a pro-survival role of these adaptors. To further evaluate the role of these proteins, gene expression studies were performed in Crk/CrkL conditionally-deficient pro-B cells. IL-7 decreased the transcription of the receptor LAIR1, which inhibits B cell proliferation, in a Crk/CrkL-dependent manner, suggesting that the Crk family of proteins may promote pro-B cell proliferation. Our data contribute to the understanding of IL-7 signaling and suggest the involvement of Crk family proteins in pathways promoting survival and proliferation. PMID- 29581032 TI - Enhancing the performance of Escherichia coli-inoculated microbial fuel cells by introduction of the phenazine-1-carboxylic acid pathway. AB - Microbial fuel cells (MFCs) are a renewable green energy source that uses microorganisms to catalytically convert chemical energy into electrical energy. The efficiency of extracellular electron transfer (EET) from the microbe cell to the anode electrode plays a key role in the MFC. However, the insulating properties of the cell membrane limit the efficiency of EET. Herein, EET efficiency was improved by introducing a phenazine synthesis pathway into Escherichia coli. Through the heterologous expression of phzA1B1C1D1E1F1G1, phenazine-1-carboxylic acid production increased, and the maximum power density increased from 16.7 mW/m2 to 181.1 mW/m2. Furthermore, the charge transfer resistance of 6.7 Omega decreased to 4.2 Omega, which reflected the enhancement of the EET efficiency and the electricity power output. Our results imply that introducing a heterologous electron shuttle into E. coli could be an efficient approach to improving the EET efficiency and performance of an MFC. PMID- 29581033 TI - Production of foot-and-mouth disease virus capsid proteins by the TEV protease. AB - Protective immunity to viral pathogens often includes production of neutralizing antibodies to virus capsid proteins. Many viruses produce capsid proteins by expressing a precursor polyprotein and related protease from a single open reading frame. The foot-and-mouth disease virus (FMDV) expresses a 3C protease (3Cpro) that cleaves a P1 polyprotein intermediate into individual capsid proteins, but the FMDV 3Cpro also degrades many host cell proteins and reduces the viability of host cells, including subunit vaccine production cells. To overcome the limitations of using the a wild-type 3Cpro in FMDV subunit vaccine expression systems, we altered the protease restriction sequences within a FMDV P1 polyprotein to enable production of FMDV capsid proteins by the Tobacco Etch Virus NIa protease (TEVpro). Separate TEVpro and modified FMDV P1 proteins were produced from a single open reading frame by an intervening FMDV 2A sequence. The modified FMDV P1 polyprotein was successfully processed by the TEVpro in both mammalian and bacterial cells. More broadly, this method of polyprotein production and processing may be adapted to other recombinant expression systems, especially plant-based expression. PMID- 29581035 TI - Validation of the Edmonton Symptom Assessment System: Ascites Modification. AB - CONTEXT: Few patient-reported outcomes are available to measure the symptoms associated with malignant-related ascites in patient care and clinical research. Although the Edmonton Symptom Assessment System: Ascites Modification (ESAS:AM) is a brief tool to measure symptoms associated with malignant-related ascites, it remains to be fully validated. OBJECTIVES: The objective of the study was to validate the ESAS:AM in Japanese cancer patients. METHODS: We assessed the internal consistency, test-retest reliability, concurrent validity, and construct validity in 292 Japanese adult patients with cancer. They completed Japanese versions of the ESAS:AM, M.D. Anderson Symptom Inventory, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, and abdominal pain/ascites subscales of the EORTC Core Quality of Life Questionnaire, 26-item pancreatic cancer module. RESULTS: Cronbach's alpha coefficient of the ESAS:AM was 0.89. The intraclass correlation coefficient on test-retest examination of its total score was 0.93 (P < 0.001). Pearson correlation coefficients of the total score of the ESAS:AM with the total score of the M.D. Anderson Symptom Inventory and abdominal pain/ascites subscales of the EORTC Core Quality of Life Questionnaire, 26-item pancreatic cancer module ranged from 0.44 to 0.81 (P < 0.001) and those with global health status/quality of life and functional subscales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 ranged from -0.40 to -0.61 (P < 0.001). The total scores of the ESAS:AM were significantly higher in 20 patients with symptomatic ascites (34 [SD, 26]) than 267 patients without symptomatic ascites (23 [SD, 19]) (P = 0.018). CONCLUSION: The ESAS:AM is a reliable and valid tool for measuring symptoms associated with malignant-related ascites and can be used in daily patient care and future epidemiological studies and clinical trials. PMID- 29581034 TI - Preference for Palliative Care in Cancer Patients: Are Men and Women Alike? AB - CONTEXT: Men and those with low educational attainment are less likely to receive palliative care. Understanding these disparities is a high priority issue. OBJECTIVES: In this study of advanced cancer patients, we hypothesized that men and those with lower levels of educational attainment would have less favorable attitudes toward palliative care. METHODS: We performed a cross-sectional analysis of data collected from 383 patients at study entry in the Values and Options in Cancer Care (VOICE) clinical trial. Patients were asked about their preferences for palliative care if their oncologist informed them that further treatment would not be helpful. Palliative care was defined as "comfort care" that focuses on "quality of life, but not a cure." Response options were definitely no, possibly no, unsure, possibly yes, and definitely yes. Those preferring palliative care (definitely or possibly yes) were compared to all others. Predictors were patient gender and education level. Covariates included age, race, disease aggressiveness, and financial strain. RESULTS: Women were more likely [odds ratio (95% CI)] than men to prefer palliative care [3.07 (1.80 5.23)]. The effect of education on preferences for palliative care was not statistically significant [0.85 (0.48-1.48)]. CONCLUSION: Significant gender differences in patients' preferences for palliative care could partially account for gender disparities in end-of-life care. Interventions to promote palliative care among men could reduce these disparities.

PMID- 29581037 TI - The Association of Body Mass Index and 20-Year All-Cause Mortality Among Patients With Stable Coronary Artery Disease. AB - BACKGROUND: Limited data exist regarding the long-term association of body mass index (BMI) and all-cause mortality among patients with stable coronary artery disease (CAD). Accordingly, the aim of this study is to explore the association between BMI and long-term all-cause mortality among patients with stable CAD. METHODS: Our study included 15,357 patients with stable CAD who were enrolled in the Bezafibrate Infarction Prevention (BIP) registry between February, 1990 and October1992, and subsequently followed-up through December 2014. RESULTS: 5051 (33%) patients were classified as normal weight (BMI 18.5-24.99kg/m2), while 7841 (51%) patients classified as overweight (BMI 25-29.99kg/m2), and 2465 (16%) as obese (BMI>=30). Kaplan-Meier survival analysis showed that at 20 years of follow up the rate of all-cause mortality was significantly higher among obese patients (67%) compared to overweight (61%) and normal weight (61%); log rank p-value for the overall difference <0.001. Multivariable analysis showed that obese patients had an independently 12% greater mortality risk compared to normal weight patients (HR=1.12; 95% CI 1.02-1.23; p=0.02), whereas, overweight patients experienced a similar mortality risk as normal weight patients (HR=0.99; 95% CI 0.92-1.06; p=0.76). The mortality risk associated with obesity was pronounced among patients younger than 65 years (p-value for interaction<0.05). CONCLUSIONS: Our findings indicate that obesity is independently associated with increased risk for long-term mortality among patients with stable coronary artery disease, whereas overweight does not appear to confer an additional risk in this population. PMID- 29581038 TI - Levosimendan Following Cardiac Surgery. AB - A best evidence topic was written to address if perioperative levosimendan improves mortality following cardiac surgery. Fourteen papers represented the best available evidence. An older meta-analysis summarising 11 of these trials concluded that there were fewer deaths in the levosimendan group compared to the control group (OR 0.41, p <0.001) however, this was driven by the results of three included trials by the same author. Three larger and more recent randomised controlled trials failed to demonstrate significant differences in mortality. We conclude that levosimendan lacks robust evidence to substantiate claims of mortality benefit in cardiac surgery patients and should not be used routinely in such patients. PMID- 29581039 TI - Arterial Access for Invasive Coronary Angiography: The 'Left Backhander'. PMID- 29581040 TI - Female False Positive Exercise Stress ECG Testing - Fact Verses Fiction. AB - BACKGROUND: Exercise stress testing is a well validated cardiovascular investigation. Accuracy for treadmill stress electrocardiograph (ECG) testing has been documented at 60%. False positive stress ECGs (exercise ECG changes with non obstructive disease on anatomical testing) are common, especially in women, limiting the effectiveness of the test. This study investigates the incidence and predictors of false positive stress ECG findings, referenced against stress echocardiography (SE) as a standard. METHODS: Stress echocardiography was performed using the Bruce treadmill protocol. False positive stress ECG tests were defined as greater than 1mm of ST depression on ECG during exertion, without pain, with a normal SE. Potential causes for false positive tests were recorded before the test. RESULTS: Three thousand consecutive negative stress echocardiograms (1036 females, 34.5%) were analysed (age 59+/-14 years. False positive (F+) stress ECGs were documented in 565/3000 tests (18.8%). F+ stress ECGs were equally prevalent in females (194/1036, 18.7%) and males (371/1964, 18.9%, p=0.85 for the difference). Potential causes (hypertension, left ventricular hypertrophy, known coronary disease, arrhythmia, diabetes mellitus, valvular heart disease) were recorded in 36/194 (18.6%) of the female F+ ECG tests and 249/371 (68.2%) of the male F+ ECG tests (p<0.0001 for the difference). CONCLUSIONS: These data suggest that F+ stress ECG tests are frequent and equally common in women and men. However, most F+ stress ECGs in men can be predicted before the test, while most in women cannot. Being female may be a risk factor in itself. These data reinforce the value of stress imaging, particularly in women. PMID- 29581041 TI - Titania and silica nanoparticles coupled to Chlorin e6 for anti-cancer photodynamic therapy. AB - In this study, light-sensitive photosensitizers (Chlorin e6, Ce6) were linked to TiO2 and SiO2 nanoparticles (NPs) in order to develop new kinds of NP-based drug delivery systems for cancer treatment by PDT. TiO2 or SiO2 NPs were modified either by the growth of a polysiloxane layer constituted of two silane reagents ((3-aminopropyl)triethoxysilane (APTES) and tetraethyl orthosilicate (TEOS)) around the core (PEGylated NPs: TiO2@4Si-Ce6-PEG, SiO2@4Si-Ce6-PEG) or simply modified by APTES alone (APTES-modified NPs: TiO2-APTES-Ce6, SiO2-APTES-Ce6). Ce6 was covalently attached onto the modified TiO2 and SiO2 NPs via an amide bond. The absorption profile of the hybridized NPs was extended to the visible region of the light. The physicochemical properties of these NPs were explored by TEM, HR-TEM, XRD, FTIR and zeta potential. The photophysical characteristics including the light absorption, the fluorescence properties and the production reactive oxygen species (1O2 and HO) were also addressed. In vitro experiments on glioblastoma U87 cells were performed to evaluate the photodynamic efficiency of the new hybridized NPs. The cells were exposed to different concentrations of NPs and illuminated (lambdaexc = 652 nm, fluence rate 10 J/cm2). In contrast to the PEGylated NPs, the APTES-modified nanosystems were found to be more efficient for PDT. An interesting photodynamic effect was observed in the case of TiO2-APTES Ce6 NPs. After illumination, the viability of U87 was decreased by 89% when they were exposed to 200 MUg/mL of TiO2-APTES-Ce6 NPs, which corresponds to 0.22 MUM of Ce6. The same effect can be obtained with free photosensitizer but using a higher concentration of 10 MUM of Ce6.

AB - OBJECTIVE: Administrative data are often used to estimate state Medicaid/Children's Health Insurance Program duration of enrollment and insurance continuity, but they are generally not used to estimate participation (the fraction of eligible children enrolled) because administrative data do not include reasons for disenrollment and cannot observe eligible never-enrolled children, causing estimates of eligible unenrolled to be inaccurate. Analysts are therefore forced to either utilize survey information that is not generally linkable to administrative claims or rely on duration and continuity measures derived from administrative data and forgo estimating claims-based participation. We introduce appendectomy-based participation (ABP) to estimate statewide participation rates using claims by taking advantage of a natural experiment around statewide appendicitis admissions to improve the accuracy of participation rate estimates. METHODS: We used Medicaid Analytic eXtract (MAX) for 2008-2010; and the American Community Survey for 2008-2010 from 43 states to calculate ABP, continuity ratio, duration, and participation based on the American Community Survey (ACS). RESULTS: In the validation study, median participation rate using ABP was 86% versus 87% for ACS-based participation estimates using logical edits and 84% without logical edits. Correlations between ABP and ACS with or without logical edits was 0.86 (P < .0001). Using regression analysis, ABP alone was a significant predictor of ACS (P < .0001) with or without logical edits, and adding duration and/or the continuity ratio did not significantly improve the model. CONCLUSION: Using the ABP rate derived from administrative claims (MAX) is a valid method to estimate statewide public insurance participation rates in children. PMID- 29581043 TI - Combinations of nanovesicles and physical methods for enhanced transdermal delivery of a model hydrophilic drug. AB - Here, we combined lipid nanovesicles (ethosomes, liposomes) as the drug carrier systems with two physical methods (electroporation, sonoporation) to enhance transdermal delivery of a hydrophilic model molecule, calcein. First, using different formulations, ethosomes greatly enhanced calcein permeation by passive diffusion compared to liposomes and calcein in buffer, which is most likely due to a synergism between the ethanol action on the stratum corneum lipids and the penetration of the elastic vesicles. Liposomes permeated poorly through the skin and, as also suggested by other authors, seem to remain confined to the outer layers of the skin. By creating localized effects, liposomes would be better suited to topical dermal delivery than transdermal delivery. Using sonoporation as the physical enhancement method, sonication (5 min) showed improvement over passive diffusion; however, only for the ethosome formulation, and not for solution and liposomes. Similarly, electroporation greatly enhanced delivery of calcein, which was again more pronounced for ethosomes than liposomes and calcein in buffer. Finally, three different transdermal delivery enhancement methods were coupled, using ethosomes as carriers, along with both electroporation and sonoporation, to investigate the potential for synergistic effects. However, these combinations failed to achieve not only synergistic effects, but also additive effects. Nevertheless, combination of the ethosome formulation of calcein with either of electroporation or sonoporation achieves significant enhancement of transdermal molecular delivery being safe for potential clinical use.

AB - OBJECTIVE: To evaluate the falciform ligament as an autologous substitute for mesentericoportal vein reconstruction during pancreaticoduodenectomy. BACKGROUND: Mesentericoportal vein reconstruction was needed in some certain cases during pancreaticoduodenectomy, and a rapidly available substitute was required. METHODS: The falciform ligament was used as an autologous substitute during pancreaticoduodenectomy in 6 patients between June 2016 and May 2017. Anticoagulation was not performed at any stage and venous patency was estimated by Color-Doppler ultrasonography and contrast-enhanced computed tomography. RESULTS: 6 patients underwent vascular resection during pancreaticoduodenectomy for malignant tumors. The falciform ligament graft, with a mean length of 26 mm (10-40), was immediately harvested and used as a lateral patch for reconstruction of the mesentericoportal vein (n = 6). Severe morbidity included Clavien grade III complications occurred in 1(16.7%) patients but there was no graft-related complications. Histological vascular invasion was present in all the patients (n = 6, 100%), and all had an R0 resection (100%). All venous reconstructions were patent (100%) after a mean follow-up of 12 (6-16) months. CONCLUSIONS: An autologous falciform ligament graft can be safely used as a lateral substitute for mesentericoportal vein reconstruction during pancreaticoduodenectomy; this could help improve the radical resection rate of malignant tumors when oncologically required. PMID- 29581045 TI - Consensus views on the optimum training curriculum for advanced minimally invasive surgery: A delphi study. AB - INTRODUCTION: There has been a wide uptake in the use of Minimal Invasive Surgery (MIS) globally across different surgical specialties. Whilst evidence exists for a structured training curriculum for basic laparoscopic surgery, there is little agreement on a complete framework for an advanced MIS training curriculum, defining the essential elements of the curriculum including the optimal assessment methods. The aim of this study is to obtain a consensus on the essential elements of a training curriculum for advanced MIS. MATERIALS AND METHODS: A Delphi study was carried out involving 57 international experts in advanced MIS across different surgical specialties. A three round survey was conducted to reach consensus on the essential domains of a curriculum. This included defining the learners, trainers and training centres; curriculum content and competency based assessment. RESULTS: Unanimous agreement was reached for the completion of basic laparoscopic training before entry into advanced training. A trainer should have reached competency in advanced MIS and attended a 'Train the trainer' course. The curriculum should be delivered as modular training, including a multi-modal approach with a structured clinical proctorship programme. Formative assessment was considered as an integral part of learning and should be performed using objective work based assessment tools such as global assessment scale (GAS) forms. Accreditation in advanced MIS can be achieved by objective assessment of technical performance of unedited videos in addition to key clinical performance outcomes. CONCLUSION: A consensus on the framework of an advanced MIS training curriculum has been achieved defining the essential elements of entry criteria, selection of trainers and training units and curriculum content. Multimodal learning, clinical proctorship programme and competency based assessment are integral parts of the curriculum. PMID- 29581046 TI - The outcome of A. Double mesh intraperitoneal repair for complex ventral hernia: A retrospective cohort study. AB - BACKGROUND: Complex ventral hernia is a challenging surgical entity, commonly attended with huge defect, loss of domain and possible soft tissue infection. It is difficult to repair, especially with multiple recurrences. Numerous methods of repair have been described with no evidence-based data available to prefer one method over the other. The purpose of this study is to determine the long-term outcome of the proposed new modification of intraperitoneal mesh repair procedure in complex ventral hernia. MATERIALS AND METHODS: This is a single-center retrospective analysis utilizing the prospectively-maintained dataset in our institution during the study period between January 2003 and June 2017. Patients who fit the inclusion criteria of having a complex ventral hernia, whether de novo or recurrent and were subjected to A. Double Mesh Intraperitoneal Repair (ADMIR) procedure were included in the study. Patients were followed up till recurrence or lost to follow through a period ranging from 6 to 174 months (mean: 142.96 +/- SE: 11.91). RESULTS: Forty-nine cases were included in this study (38 females and 11 males) with a female to male ratio of 3.5:1. The age range was from 28 to 81 years (mean 49 +/- 12.4). BMI range from 25 to 42 (mean 33.6 +/- 5.42). The ratio between the hernia sac volume and abdominal cavity volume was more than 20% in 12 patients (24.5%), who were subjected to preoperative progressive pneumoperitoneum (PPP) for an average period of two weeks. Hernias were recurrent in 28 cases (57%) and associated comorbidities were observed in 29 patients (63%). Postoperative complications occurred in 19 patients (38.7%), among them only 2 patients developed recurrence (4%) after a mean follow up period of 142 months. Five patients were lost to follow and were included in the Kaplan and Meier survival analysis. CONCLUSIONS: ADMIR procedure is successful for the repair of complex ventral hernias as it is applicable to all sites of ventral hernias. The mesh is tension free hidden within the abdomen allowing for early mobilization and the complications rate is acceptable with low recurrence rate. PMID- 29581047 TI - Results of subclavian to carotid artery bypass for occlusive disease of the common carotid artery: A retrospective cohort study. AB - BACKGROUND: Optimal treatment of significant atherosclerosis of the common carotid artery (CCA) is not well-defined. The purpose of this study was to evaluate the long-term results of prosthetic subclavian to carotid bypass for occlusive disease of the CCA. MATERIAL AND METHODS: From January 1994 to December 2015, 45 patients, mean age 67 years, underwent an ipsilateral subclavian to carotid bypass for occlusive disease of the CCA. Thirty-eight patients (84%) presented with neurologic symptoms, including transitory ischemic attacks in 29 cases and minor strokes in 9 cases. The graft material consisted of a 7 mm polytetrafluoroethylene conduit, and the distal anastomosis was done on the carotid bulb in 21 patients, on the internal carotid artery in 19 cases, and on the distal CCA in 5 cases. Median length of follow-up was 58 months. Study endpoints were the combined postoperative stroke/mortality rate, graft infection, overall late survival, freedom from ipsilateral stroke, and graft patency. RESULTS: Postoperative stroke/mortality rate was 2%. No graft infection was observed throughout follow-up. At 60 months, overall survival, freedom from stroke, and graft patency were 71% (standard error [SE] = 0.07), 98% (SE = 0.02), and 95.5% (SE = 0.06), respectively. CONCLUSIONS: Subclavian to carotid bypass allows very good patency rates and excellent protection from postoperative and late stroke, remaining a benchmark for any other treatment method. PMID- 29581048 TI - What risk of endocarditis is low enough to justify the omission of transoesophageal echocardiography in Staphylococcus aureus bacteraemia? A narrative review. AB - BACKGROUND: Recent criteria which can identify patients with Staphylococcus aureus bacteraemia (SAB) who are at very low risk of endocarditis raise the question of whether transoesophageal echocardiography (TOE) is appropriate for these patients. AIMS: To estimate the probability of occult endocarditis complicating SAB below which a TOE-guided treatment strategy no longer offers the best 180-day survival, and to examine the key uncertainties affecting this result. SOURCES: Estimates of the parameters required to calculate the Pauker Kassirer testing threshold were identified from studies published prior to 1 June 2017 using a composite search strategy that involved a systematic search for relevant controlled trials and guidelines, followed by a non-systematic iterative search of the observational literature. CONTENT: Estimates of the necessary parameters were generally consistent across the literature with the exception of the procedural mortality of TOE. In our base-case scenario (TOE mortality 0.1%), the testing threshold for TOE in apparently uncomplicated SAB was a 1.1% probability of occult endocarditis. Sensitivity analyses revealed that the procedural mortality of TOE was a key uncertainty affecting estimates of the testing threshold. IMPLICATIONS: None of the available clinical tools can place patients with SAB below this probability of endocarditis with 95% confidence. Future work in this area should concentrate on improving the precision of these tools and on exploring the value of alternative echocardiography strategies. In addition, a better understanding of the harms of TOE is required to ensure that recommendations regarding the role of this investigation in the management of patients with SAB are appropriate. PMID- 29581049 TI - Towards precision medicine in sepsis: a position paper from the European Society of Clinical Microbiology and Infectious Diseases. AB - BACKGROUND: Our current understanding of the pathophysiology and management of sepsis is associated with a lack of progress in clinical trials, which partly reflects insufficient appreciation of the heterogeneity of this syndrome. Consequently, more patient-specific approaches to treatment should be explored. AIMS: To summarize the current evidence on precision medicine in sepsis, with an emphasis on translation from theory to clinical practice. A secondary objective is to develop a framework enclosing recommendations on management and priorities for further research. SOURCES: A global search strategy was performed in the MEDLINE database through the PubMed search engine (last search December 2017). No restrictions of study design, time, or language were imposed. CONTENT: The focus of this Position Paper is on the interplay between therapies, pathogens, and the host. Regarding the pathogen, microbiologic diagnostic approaches (such as blood cultures (BCs) and rapid diagnostic tests (RDTs)) are discussed, as well as targeted antibiotic treatment. Other topics include the disruption of host immune system and the use of biomarkers in sepsis management, patient stratification, and future clinical trial design. Lastly, personalized antibiotic treatment and stewardship are addressed (Fig. 1). IMPLICATIONS: A road map provides recommendations and future perspectives. RDTs and identifying drug-response phenotypes are clear challenges. The next step will be the implementation of precision medicine to sepsis management, based on theranostic methodology. This highly individualized approach will be essential for the design of novel clinical trials and improvement of care pathways.

PMID- 29581051 TI - Febrile illness in Asia: gaps in epidemiology, diagnosis and management for informing health policy. AB - BACKGROUND: Increasing evidence is becoming available on the aetiology and management of fevers in Asia; the importance of these fevers has increased with the decline in the incidence of malaria. AIMS: To conduct a narrative review of the epidemiology and management of fevers in South and South-East Asia and to highlight gaps in our knowledge that impair evidence-based health policy decisions. SOURCES: A narrative review of papers published since 2012 on developments in fever epidemiology, diagnosis and treatment in South and South East Asia. The papers that the authors felt were pivotal, from their personal perspectives, are discussed. CONTENT: We identified 100 studies. Among the 30 studies (30%)-including both children and adults-that investigated three or more pathogens, the most frequently reported fever aetiology was dengue (reported by 15, 50%), followed by leptospirosis (eight, 27%), scrub typhus (seven, 23%) and Salmonella serovar Typhi (six, 20%). Among four studies investigating three or more pathogens in children, dengue and Staphylococcus aureus were the most frequent, followed by non-typhoidal Salmonella spp, Streptococcus pneumoniae, Salmonella serovar Typhi, and Orientia tsutsugamushi. Increased awareness is needed that rickettsial pathogens are common but do not respond to cephalosporins, and that alternative therapies, such as tetracyclines, are required. IMPLICATIONS: Many key gaps remain, and consensus guidelines for study design are needed to aid comparative understanding of the epidemiology of fevers. More investment in developing accurate and affordable diagnostic tests for rural Asia and independent evaluation of those already on the market are needed. Treatment algorithms, including simple biomarker assays, appropriate for empirical therapy of fevers in different areas of rural Asia should be a major aim of fever research. Enhanced antimicrobial resistance (AMR) surveillance and openly accessible databases of geography-specific AMR data would inform policy on empirical and specific therapy. More investment in innovative strategies facilitating infectious disease surveillance in remote rural communities would be an important component of poverty reduction and improving public health.

PMID- 29581053 TI - Prevalence and clinical significance of respiratory viruses and bacteria detected in tuberculosis patients compared to household contact controls in Tanzania: a cohort study. AB - OBJECTIVES: To describe the prevalence of respiratory pathogens in tuberculosis (TB) patients and in their household contact controls, and to determine the clinical significance of respiratory pathogens in TB patients. METHODS: We studied 489 smear-positive adult TB patients and 305 household contact controls without TB with nasopharyngeal swab samples within an ongoing prospective cohort study in Dar es Salaam, Tanzania, between 2013 and 2015. We used multiplex real time PCR to detect 16 respiratory viruses and seven bacterial pathogens from nasopharyngeal swabs. RESULTS: The median age of the study participants was 33 years; 61% (484/794) were men, and 21% (168/794) were HIV-positive. TB patients had a higher prevalence of HIV (28.6%; 140/489) than controls (9.2%; 28/305). Overall prevalence of respiratory viral pathogens was 20.4% (160/794; 95%CI 17.7 23.3%) and of bacterial pathogens 38.2% (303/794; 95%CI 34.9-41.6%). TB patients and controls did not differ in the prevalence of respiratory viruses (Odds Ratio [OR] 1.00, 95%CI 0.71-1.44), but respiratory bacteria were less frequently detected in TB patients (OR 0.70, 95%CI 0.53-0.94). TB patients with both respiratory viruses and respiratory bacteria were likely to have more severe disease (adjusted OR [aOR] 1.6, 95%CI 1.1-2.4; p 0.011). TB patients with respiratory viruses tended to have more frequent lung cavitations (aOR 1.6, 95%CI 0.93-2.7; p 0.089). CONCLUSIONS: Respiratory viruses are common for both TB patients and household controls. TB patients may present with more severe TB disease, particularly when they are co-infected with both bacteria and viruses. PMID- 29581054 TI - Typing of vancomycin-resistant enterococci with MALDI-TOF mass spectrometry in a nosocomial outbreak setting. AB - OBJECTIVES: To investigate the usefulness of matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) typing as a first-line epidemiological tool in a nosocomial outbreak of vancomycin-resistant Enterococcus faecium (VREfm). METHODS: Fifty-five VREfm isolates, previously characterized by whole-genome sequencing (WGS), were included and analysed by MALDI-TOF MS. To take peak reproducibility into account, ethanol/formic acid extraction and other steps of the protocol were conducted in triplicate. Twenty seven spectra were generated per isolate, and spectra were visually inspected to determine discriminatory peaks. The presence or absence of these was recorded in a peak scheme. RESULTS: Nine discriminatory peaks were identified. A characteristic pattern of these could distinguish between the three major WGS groups: WGS I, WGS II and WGS III. Only one of 38 isolates belonging to WGS I, WGS II or WGS III was misclassified. However, ten of the 17 isolates not belonging to WGS I, II or III displayed peak patterns indistinguishable from those of the outbreak strain. CONCLUSIONS: Using visual inspection of spectra, MALDI-TOF MS typing proved to be useful in differentiating three VREfm outbreak clones from each other. However, as non-outbreak isolates could not be reliably differentiated from outbreak clones, the practical value of this typing method for VREfm outbreak management was limited in our setting. PMID- 29581055 TI - Evaluation of the Roche LightMix Gastro parasites multiplex PCR assay detecting Giardia duodenalis, Entamoeba histolytica, cryptosporidia, Dientamoeba fragilis, and Blastocystis hominis. AB - OBJECTIVES: Multiplex PCR assays offer highly sensitive and specific tools for the detection of enteric pathogens. This prospective study aimed at comparing the novel Roche LightMix Modular Assay Gastro Parasites (LMAGP) detecting Giardia duodenalis, Entamoeba histolytica, Cryptosporidium spp., Blastocystis hominis, and Dientamoeba fragilis with routine laboratory procedures. METHODS: Stool specimens (n = 1062 from 1009 patients) were consecutively examined by LMAGP, R Biopharm Ridascreen enzyme immunoassays (EIAs) detecting G. duodenalis or E. histolytica/dispar, and microscopy of wet mounts. Discrepant results were analysed by in-house PCR. RESULTS: D. fragilis or B. hominis were detected by LMAGP in 131 (14.4%) and 179 (19.9%; 16 samples positive by microscopy; p < 0.0001) of 909 samples, respectively. Of 918 samples analysed for Cryptosporidium spp., six were positive by LMAGP (three could be confirmed by Kinyoun staining and one by in-house PCR). G. duodenalis was detected by LMAGP, EIA, or microscopy in 20, 16, or 9 of 1039 stool samples, respectively; all four samples missed by EIA were confirmed by in-house PCR. In total, 938 stool samples were analysed for E. histolytica/dispar. Nine of ten EIA-positive samples were negative by LMAGP but positive by in-house PCR for E. dispar. One E. histolytica infection (positive by both LMAGP and in-house PCR) was missed by EIA and microscopy. Parasites only detected by microscopy included Enterobius vermicularis eggs (n = 3) and apathogenic amoebae (n = 27). CONCLUSIONS: The data call for routine use of multiplex PCR assays for the detection of enteric protozoan parasites in laboratory diagnostics. PMID- 29581056 TI - Development of diagnostic prediction tools for bacteraemia caused by third generation cephalosporin-resistant enterobacteria in suspected bacterial infections: a nested case-control study. AB - OBJECTIVES: Current guidelines for the empirical antibiotic treatment predict the presence of third-generation cephalosporin-resistant enterobacterial bacteraemia (3GCR-E-Bac) in case of infection only poorly, thereby increasing unnecessary carbapenem use. We aimed to develop diagnostic scoring systems which can better predict the presence of 3GCR-E-Bac. METHODS: A retrospective nested case-control study was performed that included patients >=18 years of age from eight Dutch hospitals in whom blood cultures were obtained and intravenous antibiotics were initiated. Each patient with 3GCR-E-Bac was matched to four control infection episodes within the same hospital, based on blood-culture date and onset location (community or hospital). Starting from 32 commonly described clinical risk factors at infection onset, selection strategies were used to derive scoring systems for the probability of community- and hospital-onset 3GCR-E-Bac. RESULTS: 3GCR-E-Bac occurred in 90 of 22 506 (0.4%) community-onset infections and in 82 of 8110 (1.0%) hospital-onset infections, and these cases were matched to 360 community-onset and 328 hospital-onset control episodes. The derived community onset and hospital-onset scoring systems consisted of six and nine predictors, respectively. With selected score cut-offs, the models identified 3GCR-E-Bac with sensitivity equal to existing guidelines (community-onset: 54.3%; hospital-onset: 81.5%). However, they reduced the proportion of patients classified as at risk for 3GCR-E-Bac (i.e. eligible for empirical carbapenem therapy) with 40% (95%CI 21-56%) and 49% (95%CI 39-58%) in, respectively, community-onset and hospital onset infections. CONCLUSIONS: These prediction scores for 3GCR-E-Bac, specifically geared towards the initiation of empirical antibiotic treatment, may improve the balance between inappropriate antibiotics and carbapenem overuse.

AB - AIM: Our study objectives were to evaluate umbilical cord blood acid-base balance in presence of nuchal cord at delivery, effects of nuchal cord at delivery on perinatal outcomes and incidence of nuchal cord in a racially diverse population. METHODS: Perinatal records of 2530 women (predominantly African American and Hispanic) who delivered in 2012 were examined. Perinatal outcomes of women who delivered a baby with nuchal cord were compared with those without nuchal cord. RESULTS: In this study, incidence of nuchal cord was 23.5% and incidence of tight nuchal cord was 1.9%; 4.2% of babies with nuchal cord required resuscitation and 3.2% of babies with nuchal cord needed to be admitted to NICU. In our study, 4.2% of babies with nuchal cord required resuscitation and in total 3.2% of babies with nuchal cord needed to be admitted to NICU. Nuchal cord frequency increased from 15.6% at <=36 weeks to 22.8% at >=37 weeks. Significantly elevated umbilical cord Veno-Arterial pH differential was noted in babies with nuchal cord, indicating fetal acidemia. CONCLUSIONS: Perinatal outcomes of pregnancies with nuchal cord in predominantly African American and Hispanic women were not adversely affected. Analysis of umbilical cord blood gases suggests mixed respiratory and metabolic fetal acidosis. PMID- 29581059 TI - Dissociable effects of inter-stimulus interval and presentation duration on rapid face categorization. AB - Fast periodic visual stimulation combined with electroencephalography (FPVS-EEG) has unique sensitivity and objectivity in measuring rapid visual categorization processes. It constrains image processing time by presenting stimuli rapidly through brief stimulus presentation durations and short inter-stimulus intervals. However, the selective impact of these temporal parameters on visual categorization is largely unknown. Here, we presented natural images of objects at a rate of 10 or 20 per second (10 or 20 Hz), with faces appearing once per second (1 Hz), leading to two distinct frequency-tagged EEG responses. Twelve observers were tested with three squarewave image presentation conditions: 1) with an ISI, a traditional 50% duty cycle at 10 Hz (50-ms stimulus duration separated by a 50-ms ISI); 2) removing the ISI and matching the rate, a 100% duty cycle at 10 Hz (100-ms duration with 0-ms ISI); 3) removing the ISI and matching the stimulus presentation duration, a 100% duty cycle at 20 Hz (50-ms duration with 0-ms ISI). The face categorization response was significantly decreased in the 20 Hz 100% condition. The conditions at 10 Hz showed similar face categorization responses, peaking maximally over the right occipito-temporal (ROT) cortex. However, the onset of the 10 Hz 100% response was delayed by about 20 ms over the ROT region relative to the 10 Hz 50% condition, likely due to immediate forward-masking by preceding images. Taken together, these results help to interpret how the FPVS-EEG paradigm sets temporal constraints on visual image categorization. PMID- 29581060 TI - Performance-monitoring integrated reweighting model of perceptual learning. AB - Perceptual learning (PL) has been traditionally thought of as highly specific to stimulus properties, task and retinotopic position. This view is being progressively challenged, with accumulating evidence that learning can generalize (transfer) across various parameters under certain conditions. For example, retinotopic specificity can be diminished when the proportion of easy to hard trials is high, such as when multiple short staircases, instead of a single long one, are used during training. To date, there is a paucity of mechanistic explanations of what conditions affect transfer of learning. Here we present a model based on the popular Integrated Reweighting Theory model of PL but departing from its one-layer architecture by including a novel key feature: dynamic weighting of retinotopic-location-specific vs location-independent representations based on internal performance estimates of these representations. This dynamic weighting is closely related to gating in a mixture-of-experts architecture. Our dynamic performance-monitoring model (DPMM) unifies a variety of psychophysical data on transfer of PL, such as the short-vs-long staircase effect, as well as several findings from the double-training literature. Furthermore, the DPMM makes testable predictions and ultimately helps understand the mechanisms of generalization of PL, with potential applications to vision rehabilitation and enhancement. PMID- 29581061 TI - Evaluation of some effects on plant metabolism through proteins and enzymes in transgenic and non-transgenic soybeans after cultivation with silver nanoparticles. AB - : To evaluate the effects of silver nanoparticles (AgNP) exposition, transgenic (through gene cp4EPSPS) and non-isogenic non-transgenic soybeans were cultivated in the presence or absence of AgNP or silver nitrate (AgNO3) at 50 mg/kg of silver. Physiological aspects of the plants including mass production and development of roots, proteomics such as protein amount and differential proteins, enzymes and lipid peroxidation were determined after exposition. The mass production of non-transgenic plants treated with AgNP or AgNO3 was decreased by 25 and 19%, respectively, on their mass based, while for transgenic soybean this effect was observed for AgNP cultivation only. Fifty-nine proteins were identified from the differentially abundant spots by two-dimensional difference gel electrophoresis and nano-electrospray ionization liquid chromatography coupled tandem mass spectrometry. Identified species as ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), ATP synthase, superoxide dismutase (SOD), related to plant metabolism were less abundant for the cultivation with either AgNP and AgNO3 than the control. Finally, this work demonstrated significant correlation as evidenced by changes in lipid peroxidation content and catalase activity, which were a result of exposure to either AgNP or AgNO3 cultivations. Further, necrotic areas in the basal part of the stems and damage or chlorotic areas were found in the leaves. SIGNIFICANCE: Once nanoparticles have been employed for several applications in recent years and they can be released in the environmental matrices, this study highlights proteomic and enzymatic alterations in transgenic and non-transgenic soybeans, an important crop, after cultivation with silver nanoparticles. Such strategy employing proteomic and enzymatic approaches to evaluate soybeans exposed to silver nanoparticles has not yet been reported. Therefore, the results obtained in this study can expand the information concerning the effects of silver nanoparticles in soybean plants. PMID- 29581062 TI - Editorial: A matter of ingredients. PMID- 29581063 TI - Characterization of rat primary trigeminal satellite glial cells and associated extracellular vesicles under normal and inflammatory conditions. AB - Satellite glial cells (SGCs) in sensory ganglia contribute to the pathogenesis of chronic pain, potentially through mediating extracellular or paracrine signaling. Recently, extracellular vesicles (EVs) in the form of exosomes have been found to play an important role in cell-cell communication. However, their release from SGCs and extent in modulating pain remain unknown. An in vitro cell platform using fresh primary SGCs was used to characterize the shed vesicles by size and proteomic profiling following activation of SGCs by lipopolysaccharide (LPS), simulating neurogenic inflammation in vivo. Results demonstrated that SGCs shed vesicles in the size range of exosomes (>150 nm) but with altered protein expression upon LPS-activation. Proteomic profiling of SGCs-shed EVs showed that a number of proteins were differentially regulated upon LPS stimulation such as junction plakoglobin and myosin 9 that are proposed as novel biomarkers of SGCs activation under inflammatory conditions. Findings from this study highlight the utility of using fresh primary SGC cultures as a model to further investigate EVs under normal and inflammatory conditions. SIGNIFICANCE: This study demonstrated that. PMID- 29581064 TI - Molecular signatures of medullary thyroid carcinoma by matrix-assisted laser desorption/ionisation mass spectrometry imaging. AB - : The main aim of the study was to assess the feasibility of matrix-assisted laser desorption/ionisation mass spectrometry imaging (MALDI-MSI) in the pathological investigation of Medullary Thyroid Carcinoma (MTC). Formalin-fixed paraffin-embedded (FFPE) samples from seven MTC patients were analysed by MALDI MSI in order to detect proteomic alterations within tumour lesions and to define the molecular profiles of specific findings, such as amyloid deposition and C cell hyperplasia (CCH). nLC-ESI MS/MS was employed for the identification of amyloid components and to select alternative proteomic markers of MTC pathogenesis. Results highlighted the potential of MALDI-MSI to confirm the classic immunohistochemical methods employed for the diagnosis of MTC, with good sensitivity and specificity. Intratumoural amyloid components were also detected and identified, and were characterised by calcitonin, apolipoprotein E, apolipoprotein IV, and vitronectin. The tryptic peptide profiles representative of MTC and CCH were distinctly different, with four alternative markers for MTC being detected; K1C18, and three histones (H2A, H3C, and H4). Finally, a further 115 proteins were identified through the nLC-ESI-MS/MS analysis alone, with moesin, veriscan, and lumican being selected due to their potential involvement in MTC pathogenesis. This approach represents a complimentary strategy that could be employed to detect new proteomic markers of MTC. STATEMENT OF SIGNIFICANCE: Medullary thyroid carcinoma (MTC) is a rare endocrine malignancy that originates from the parafollicular C-cells of the thyroid. The diagnosis is typically established using a combination of fine-needle aspiration biopsy (FNAB) of a suspicious nodule along with the demonstrable elevation of serum biomarkers, such as calcitonin and carcinoembryonic antigen (CEA). Unfortunately, this combination is often associated with a high degree of false-positive results and this can lead to misdiagnosis and avoidable total thyroidectomy. The current study presents the potential role of MALDI-MSI in the search for new proteomic markers of MTC with diagnostic and prognostic significance. MALDI-MSI was capable of detecting the classic immunohistochemical markers employed for the diagnosis of MTC, with good sensitivity and specificity. Furthermore, the complementary combination of MALDI-MSI and nLC-ESI-MS/MS analysis, using a single tissue section, enabled further potential markers to be identified and their spatial localisation visualised within tumoural regions. Such findings could be a valuable starting point for further studies focused on confirming the data presented here using thyroid FNABs, with the final objective being to provide complimentary assistance for the detection of MTC during the pre-operative phase. PMID- 29581066 TI - No lower bacterial adhesion for ceramics compared to other biomaterials: An in vitro analysis. AB - BACKGROUND: Although there is some clinical evidence of ceramic bearings being associated with a lower infection rate after total hip arthroplasty (THA), available data remains controversial since this surface is usually reserved for young, healthy patients. Therefore, we investigated the influence of five commonly used biomaterials on the adhesion potential of four biofilm-producing bacteria usually detected in infected THAs. HYPOTHESIS: Ceramic biomaterials exhibit less bacterial adherence than other biomaterials. MATERIAL AND METHODS: In this in vitro research, we evaluated the ability of Staphylococcus aureus, Staphylococcus epidermidis ATCC 35984, Escherichia coli ATCC 25922 and Pseudomonas aeruginosa to adhere to the surface of a cobalt-chromium metal head, a fourth-generation ceramic head, a fourth-generation ceramic insert, a highly crossed linked polyethylene insert and a titanium porous-coated acetabular component. After an initial washing step, bacterial separation from the surface of each specimen was done with a vortex agitator. The colony-forming units were counted to determine the number of viable adherent bacteria. RESULTS: We found no differences on global bacterial adhesion between the different surfaces (p=0.5). E. coli presented the least adherence potential among the analysed pathogens (p<0.001). The combination of E. coli and S. epidermidis generated an antagonist effect over the adherence potential of S. epidermidis individually (58+/-4% vs. 48+/-5%; p=0.007). The combination of P. aeruginosa and S. aureus presented a trend to an increased adherence of P. aeruginosa independently, suggesting an agonist effect (71% vs. 62%; p=0.07). DISCUSSION: Ceramic bearings appeared not to be related to a lower bacterial adhesion than other biomaterials. However, different adhesive potentials among bacteria may play a major role on infection's inception. LEVEL OF EVIDENCE: IV, in vitro study. PMID- 29581065 TI - Micelle directed chemical polymerization of polypyrrole particles for the electrically triggered release of dexamethasone base and dexamethasone phosphate. AB - Conducting polymers such as polypyrrole (PPy) can be used as electrically responsive drug delivery systems typically prepared by electrochemical polymerisation, however, the amount of drug that can be delivered is typically low. To increase drug delivery capacity and prepare larger amounts of polymer, PPy nanoparticles were produced by chemical polymerisation over drug-loaded micelles. Two forms of dexamethasone were included to increase total drug loading and to explore the mechanisms of loading and release. The particles produced were approximately 50 nm in size and their conductivity and reversible redox activity were demonstrated. Loading of the hydrophobic dexamethasone base was more efficient than for the more hydrophilic phosphate salt. After pressing the particles into the desired form, electrically-responsive drug release was achieved with a pulsed potential signal being the most effective way to trigger release. Notably, the anionic phosphate salt of the drug was more sensitive to electrically stimulated release than the uncharged base of dexamethasone, highlighting the role of electrostatic forces in driving drug release. This system has potential to be loaded with different drugs widening the scope of application of these smart particles to treat a range of disease states. PMID- 29581067 TI - The use of the LARS system in the treatment of AC joint instability - Long-term results after a mean of 7.4 years. AB - BACKGROUND: The acromioclavicular (AC) joint is of great importance for shoulder stability and one of the most frequently injured regions of the shoulder. HYPOTHESIS: AC joint reconstruction with the ligament augmentation & reconstruction system (LARSTM) leads to a good-to-excellent outcome at long-term follow-up. PATIENTS AND METHODS: This study was performed as a retrospective single-centre data analysis of a level-I trauma centre. All patients treated operatively for an acute AC dislocation with the LARSTM between 2003 and 2013 were included. RESULTS: The study group consisted of three female (6%) and 44 male patients (94%) with an average age of 37 years and a minimum follow-up of two years. The overall mean clinical outcomes at latest follow-up were: Constant 93, DASH 2.64, ASES 96, SST 97, UCLA 34 and VAS 0.4-representing a good-to excellent outcome in all patients. Overall, 45 patients (96%) reported to be very satisfied with the achieved result at latest follow-up. In five patients, (11%) complications occurred during the follow-up period, requiring surgical revision in four of the five patients (80%). CONCLUSION: AC joint reconstruction with the LARSTM achieves good-to-excellent clinical and functional outcomes at long-term follow-up with a surgical revision rate of 8.5%.

AB - BACKGROUND: There are several reports regarding total hip arthroplasty (THA) after a previous pelvic osteotomy (PO). However, to our knowledge, until now there has been no formal systematic review and meta-analysis published to summarize the clinical results of THA after a previous PO. Therefore, we conducted a systematic review and meta-analysis of results of THA after a previous PO. We focus on these questions as follows: does a previous PO affect the results of subsequent THA, such as clinical outcomes, operative time, operative blood loss, and radiological parameters. METHODS: Using PubMed, Web of Science, and Cochrane Library, we searched for relevant original papers. The pooling of data was performed using RevMan software (version 5.3, Cochrane Collaboration, Oxford, UK). A p-value<0.05 was judged as significant. Standardized mean differences (SMD) were calculated for continuous data with a 95% confidence interval (CI) was reported. Statistical heterogeneity was assessed based on I2 using standard chi2 test. When I2>50%, significant heterogeneity was assumed and a random-effects model was applied for the meta-analysis. A fixed effects model was applied in the absence of significant heterogeneity. RESULTS: Eleven studies were included in this meta-analysis. The pooled results indicated that there was no significant difference in postoperative Merle D'Aubigne-Postel score (I2=0%, SMD=-0.15, 95% CI: -0.36 to 0.06, p=0.17), postoperative Harris hip score (I2=60%, SMD=-0.23, 95% CI: -0.50 to 0.05, p=0.10), operative time (I2=86%, SMD=0.37, 95% CI: -0.09 to 0.82, p=0.11), operative blood loss (I2=82%, SMD=0.23, 95% CI: -0.17 to 0.63, p=0.25), and cup abduction angle (I2=43%, SMD=-0.08, 95% CI: -0.25 to 0.09, p=0.38) between THA with and without a previous PO. However, cup anteversion angle of THA with a previous PO was significantly smaller than that of without a previous PO (I2=77%, SMD=-0.63, 95% CI: -1.13 to -0.13, p=0.01). CONCLUSION: Systematic review and meta-analysis of results of THA after a previous PO was performed. A previous PO did not affect the results of subsequent THA, except for cup anteversion. Because of the low quality evidence currently available, high-quality randomized controlled trials are required. LEVEL OF EVIDENCE: Level III, meta-analysis of case-control studies. PMID- 29581069 TI - Capitellar erosion after radial head arthroplasty: A comparative biomechanical study of operated radial head fractures on cadaveric specimens. AB - BACKGROUND: We asked whether open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA), common techniques used for the confrontation of displaced or comminuted radial head fractures, are correlated with cartilage wear of the capitulum. HYPOTHESIS: We hypothesized that neither ORIF nor RHA are correlated with capitellar cartilage wear. MATERIAL AND METHODS: On 5 cadaveric elbow specimens, osteotomies were employed to simulate radial head comminuted fractures followed with ORIF by Herbert screws. Radial heads were also excised from other 5 cadaveric elbow specimens and were replaced by metallic monopolar implants. Finally, 2 elbows were not operated and used as a control group. Custom made rotary machines, working unstoppably, generated 700,000 pronation and supination forearm movements at a 110 degrees arc of motion. The elbow joints were examined with pre- and postoperative magnetic resonance imaging (MRI) scans and the articular surfaces of the capitula were resected and sent for histopathology study. RESULTS: In the 2 cadaveric elbows of the control group and the 4 elbows treated with ORIF, no cartilage damage was found. The fifth one displayed cartilage fissures, which were, classified according to International Cartilage Repair Society (ICRS) grading system as grade I cartilage damage. On the contrary, all 5 elbows treated with RHA sustained complete cartilage loss, exposure of the subchondral bone and were classified as ICRS grade IV cartilage damage. DISCUSSION: Our study suggests that metallic monopolar RHA after a displaced or comminuted radial head fracture carries a high risk of rapidly evolving cartilage loss of the capitulum. PMID- 29581070 TI - Diagnostic accuracy of the alpha defensin lateral flow device (Synovasure) for periprosthetic infections in microbiologically complex situations: A study of 42 cases in a French referral centre. AB - BACKGROUND: Joint aspiration is currently the reference standard test for diagnosing periprosthetic joint infection (PJI) despite the high rate of false negative results, of which a major cause is the fastidious nature of some microorganisms. A rapid diagnostic test that detects alpha defensin (SynovasureTM, Zimmer, Warsaw, IN, USA) in joint fluid can provide the diagnosis of PJI within a few minutes across the full spectrum of causative organisms (including mycobacteria and yeasts). Its performance in detecting bacterial infections is unaltered by concomitant antibiotic therapy. Few studies of SynovasureTM have been conducted by groups that were involved in designing the test, which has not been validated in France. Assessments in referral centres where complex microbiological situations are common hold considerable interest. The objective of this prospective study was to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and causes of error of SynovasureTM used to diagnose periprosthetic infection in complex microbiological situations. HYPOTHESIS: The rapid diagnostic test SynovasureTM has greater than 90% NPV for detecting periprosthetic infections in complex microbiological infections. MATERIAL AND METHODS: SynovasureTM was used 42 times in 39 patients between October 2015 and October 2017 in challenging microbiological situations [discordant joint aspiration results (n=20), negative cultures with clinical or laboratory evidence of infection, (n=21), and concomitant antibiotic therapy (n=1)]. Of the 39 patients, 23 had total knee prostheses, 13 total hip prostheses, and 3 total femoral prostheses. The reference standard to which the SynovasureTM results were compared was the PJI criteria set developed by the Musculoskeletal Infection Society (MSIS). RESULTS: SynovasureTM was negative in 30 cases with negative joint fluid cultures (30/42, 71.4%). Of the 12 (28.6%) cases with positive SynovasureTM results, only 7 (7/12, 58.3%) had positive joint fluid cultures. According to the MSIS criteria 9 cases were infected, including 8 with positive and 1 with negative SynovasureTM results. Of the 33 cases that were not infected according to MSIS criteria, 29 had negative and 3 positive SynovasureTM results; the remaining case had a positive SynovasureTM result but was excluded when metallosis was found intra operatively. NPV was 96.7%, PPV 72.7%, sensitivity 88.9%, and specificity 90.6%. DISCUSSION: The high NPV of SynovasureTM suggests a role for this test in microbiologically complex situations as a new tool for ruling in and, most importantly, ruling out infection in doubtful cases.

AB - BACKGROUND: Locking compression plates have become increasingly popular in orthopaedic surgery. However, the gold standard of treatment for distal fibular fractures remains fixation with a non-locking one-third tubular plate. It has been reported that locking plates in distal fibular fractures are associated with an increased complication rate. HYPOTHESIS: The objective of this study is to assess the complication rates of locking versus non-locking plates in patients who underwent surgical fixation of distal fibular fractures. MATERIALS & METHODS: A retrospective analysis of closed distal fibular fractures that underwent surgical repair over a 2-year period with either a locking or non-locking plate was undertaken, analysing the groups for both wound and overall postoperative complications. RESULTS: A total of 160 patients were treated over 2 years, of which 129 and 31 patients were treated with non-locking and locking plates respectively. There was no significant difference between the non-locking and locking plates overall complication rates (13.5% versus 15.4%, p=0.76) or wound complication rates (3.97% versus 3.85%, p=1.00). DISCUSSION: Distal fibular fractures managed with locking plates do not have a higher complication rate in comparison to those managed with non-locking plates.

PMID- 29581074 TI - Antimicrobial susceptibility profiles of bacteria causing urinary tract infections in Mexico: Single-centre experience with 10 years of results. AB - OBJECTIVES: The aim of this retrospective study was to describe urinary tract infections (UTIs) diagnosed in a single centre in Mexico through 10 years of results, with a particular emphasis on the aetiology, patterns of antimicrobial susceptibility and incidence of extended-spectrum beta-lactamase (ESBL)-producing strains. METHODS: This study involved all urine samples analysed during the period March 2007 to September 2017 in a single centre in Mexico. Isolated uropathogens were identified to species level using routine laboratory methods, and antimicrobial susceptibility was determined by the disk diffusion method. RESULTS: Overall, 859 urinary isolates were identified, including 582 (67.8%) Escherichia coli, 69 (8.0%) Enterococcus faecalis, 29 (3.4%) Klebsiella pneumoniae, 24 (2.8%) Proteus mirabilis, 24 (2.8%) Pseudomonas aeruginosa, 23 (2.7%) Candida albicans, 18 (2.1%) Streptococcus agalactiae and 10 (1.2%) Candida glabrata. Patient sex and age were the main risk factors associated with UTI in this population. Nitrofurantoin together with fosfomycin and amikacin had the highest percentages of susceptibility. Of the 859 isolates, 213 (24.8%) presented a positive double-disk synergy test indicating the presence of an ESBL phenotype, with E. coli showing a gradual increase in ESBL-producing isolates over time. CONCLUSIONS: These results provide additional evidence in relation to the role of different bacterial species as aetiological agents of UTI as well as antimicrobial susceptibility information that will help to guide the selection of antimicrobial treatment for UTIs and the prevalence of ESBL-producing strains over a 10-year period in a Mexican centre. PMID- 29581076 TI - Helicobacter pylori therapy and clinical perspective. AB - Helicobacter pylori induces chronic gastritis and duodenal ulcer in a small fraction of the colonised population. Three decades after the discovery of H. pylori and disclosure of an urgent need for eliminating the bacterium in patients, it seems that we are still in the first steps of dealing with this mysterious organism. Treatment of H. pylori is a complex dilemma for clinicians, a repeating sentence by many scientists who spend years on this research topic. Apart from many modifications in initial first-line treatment of H. pylori, gastroenterologists are unable to overcome the problem of therapeutic failure. Choosing the best regimen in any region depends on many factors, which have been the focus of many randomised clinical trials. A potential increase in efficacy of future therapies may be influenced by adding the novel potassium-competitive acid blocker vonoprazan. Undeniably, in-depth analysis is necessary to propose more effective therapeutic regimens. Meanwhile, we recommend the performance of antimicrobial susceptibility testing before any antimicrobial prescription. PMID- 29581075 TI - Distribution of extended-spectrum beta-lactam, quinolone and carbapenem resistance genes, and genetic diversity among uropathogenic Escherichia coli isolates in Tehran, Iran. AB - OBJECTIVES: Antimicrobial resistance among uropathogenic Escherichia coli (UPEC) is increasing. The aim of this study was to evaluate antimicrobial resistance in UPEC isolates and its correlation with virulence factors. METHODS: A total of 120 E. coli isolates were collected from patients with urinary tract infection in Tehran, Iran. Biofilm formation and antimicrobial susceptibility were determined by phenotypic tests. The combination disk diffusion test and modified Hodge test (MHT) were performed for phenotypic detection of extended-spectrum beta lactamases (ESBLs) and carbapenemases, respectively. PCR was used for the detection of virulence genes, ESBL-encoding genes, and quinolone (qnr) and carbapenem resistance genes. Pulsed-field gel electrophoresis (PFGE) was performed to explore the genetic relatedness among isolates. RESULTS: Most isolates exhibited biofilm formation, and different frequencies of virulence genes were observed. There was a high rate of resistance, especially multidrug resistance, to most of the antimicrobial agents tested. Phenotypically, 67.5% of the isolates produced an ESBL and were resistant to different antimicrobial classes. In total, 83.3% of the isolates harboured ESBL genes, especially blaTEM and blaCTX-M, and 32.5% were positive for the quinolone resistance genes qnrS and qnrB. All isolates were negative for carbapenemases by the MHT and PCR. These results indicate the association between the presence of various virulence genes and antimicrobial susceptibility. PFGE analysis showed that there was great clonal diversity among the selected isolates, with 17 isolates divided into five clusters. CONCLUSIONS: These results indicate that the high antimicrobial resistance among UPEC isolates is alarming and requires urgent attention.

PMID- 29581078 TI - Alogliptin in Patients with Type 2 Diabetes Receiving Metformin and Sulfonylurea Therapies in the EXAMINE Trial. AB - BACKGROUND: We evaluated the antihyperglycemic efficacy and safety of adding the dipeptidyl dipeptidase-4 inhibitor alogliptin to metformin and sulphonylurea in the treatment of type 2 diabetes in the Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care Trial. METHODS: Patients with type 2 diabetes and recent acute coronary syndrome were randomized to alogliptin or placebo and standard of care. Participants were followed for up to 40 (median 18) months. In a subgroup taking metformin and sulphonylurea at baseline, we evaluated change from baseline in glycated hemoglobin (HbA1c), adverse events, cardiovascular outcomes, laboratory data, and other safety parameters. RESULTS: There were 1398 patients receiving baseline dual therapy (metformin and sulphonylurea only) randomized to alogliptin (N = 693) or placebo (N = 705); 550 patients receiving alogliptin and 505 patients receiving placebo completed the Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care without addition of other antihyperglycemic therapies (P = .008). Changes from baseline to last visit in HbA1c were -0.4% on alogliptin and +0.1% on placebo (P < .001) in all those with baseline dual therapy and -0.4% for alogliptin and +0.2% for placebo (P < .001) in those without additional therapies. Reported rates of hypoglycemia were 8.8% for alogliptin and 6.7% for placebo (P = .16). Cardiovascular death and all-cause mortality rates were lower in those receiving alogliptin compared with those receiving placebo (hazard ratio, 0.49; 95% confidence interval, 0.28-0.84 and hazard ratio, 0.61; 95% confidence interval, 0.38-0.96, respectively). CONCLUSIONS: Addition of the dipeptidyl peptidase-4 inhibitor alogliptin to dual therapy with metformin plus sulfonylurea significantly reduced HbA1c and was well tolerated. Lower mortality rates were seen in patients treated with alogliptin in this subgroup. PMID- 29581079 TI - Thiazolidinediones and Risk of Atrial Fibrillation Among Patients with Diabetes and Coronary Disease. AB - BACKGROUND: We sought to determine whether insulin-sensitizing therapy (thiazolidinediones or metformin) decreased the risk of developing atrial fibrillation compared with insulin-providing therapy (insulin, sulfonylurea, or a meglitinide). Thiazolidinediones are insulin sensitizers that also decrease the inflammatory response. Because inflammation is a risk factor for atrial fibrillation, we hypothesized that treating diabetes with thiazolidinediones might decrease the risk of developing atrial fibrillation. METHODS: The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial enrolled patients with type 2 diabetes and documented coronary artery disease. All patients were randomized to insulin-sensitizing therapy or insulin-providing therapy. RESULTS: A total of 2319 patients entered the study, with 1160 assigned to the insulin-sensitization strategy and 1159 assigned to the insulin-provision strategy. Over a median follow-up of 4.2 years, 90 patients (3.9%) developed new onset atrial fibrillation. In the intention-to-treat analysis, the incidence of atrial fibrillation was 8.7 per 1000 person-years in patients assigned to insulin sensitization compared with 9.5 in patients assigned to insulin provision with a hazard ratio (HR) of 0.91 (95% confidence interval [CI], 0.60-1.38, P = .66). In a time-varying exposure analysis, the incidence rate per 1000 person-years was 7.2 while exposed to thiazolidinediones and 9.7 while not exposed to thiazolidinediones with an adjusted HR of 0.80 (95% CI, 0.33-1.94, P = .62). In a subset of patients matched on propensity to receive a thiazolidinediones, the HR was 0.75 (95% CI, 0.43-1.30, P = .30). CONCLUSIONS: We did not find a significant reduction of atrial fibrillation incidence with use of thiazolidinediones. PMID- 29581080 TI - Persistent Profound Lactic Acidosis: an Unusual Case. PMID- 29581081 TI - Silencing SOCS1 in dendritic cells promote survival of mice with systemic Candida albicans infection via inducing Th1-cell differentiation. AB - Enhancing the immunity conferred by dendritic cells (DCs) to fungal infection represents a promising strategy in the number of immunocompromised individuals. In a previous study, we demonstrated that suppressor of cytokine signaling 1 (SOCS1) silencing can promote the maturation of DCs and induce an immune response against Candida albicans (C. albicans) in vitro. Herein, the effectiveness of SOCS1 suppression administered by SOCS1-siRNA-treated DCs is further evaluated in systemic candidiasis mouse model. The SOCS1-silenced DCs increase mouse survival and significantly decrease fungal colonization in the kidneys. We confirm that the serum IFN-gamma levels in SOCS1-siRNA-treated mice are higher than in all other infected groups at the early stages of infection, which correlates with a higher differentiation of IFN-gamma+CD4+ T cells (Th1) in the spleen. Meanwhile, the differentiation of IL-4-producing CD4+ T (Th2) or IL-17-producing CD4+ T cells (Th17 cells) remain unaffected under the same treatment, suggesting that SOCS1-silenced DCs significantly affect the IFN-gamma-producing CD4+ T cells (Th1). However, at the late stages of infection when the differentiation of Th1, Th2 and Th17 cells decreases in SOCS1-silenced-DCs-treated mice, all the serum cytokines (IFN-gamma, IL-4 and IL-17) are also reduced. In summary, treatment of mice with SOCS1-silenced DCs can protect mice from systemic infection during the early stages and thereby increase overall survival. We conclude that the increase in Th1 response in early stages avoids the cascade inflammatory response in later stages that is known to place such a large fungal load on the kidneys and cause subsequent death. PMID- 29581083 TI - Long-term predictors for psychological outcome of pre-symptomatic testing for late-onset neurological diseases. AB - This longitudinal study aimed at determining predicting variables for middle and long-term psychological disturbance due pre-symptomatic testing (PST) for two late-onset neurological diseases, Huntington disease (HD) and TTR (transthyretin protein) familial amyloid polyneuropathy (FAP) Val30Met (now classified as Val50Met). 196 clinical records of persons who performed PST at least three years ago and answered to the two stages of evaluation (before PST and least 3 years after disclosure of results) were analysed. For this purpose, regression analysis was performed, showing that the Positive Symptom Distress Index (PSDI), psychoticism, somatization and paranoid ideation dimensions assume predictive value in the middle and long-term impact for total anxiety and PSDI. The result of PST was not a relevant predictor. The application of an evaluation instrument of various psychopathological dimensions played a fundamental role in the detection of clinical situations that may arise several years later after PST. Attention should be paid to providing psychological support to persons at-risk who, at the pre-test phase, present some psychopathology indices before pursuing with genetic testing. PMID- 29581082 TI - Methylmercury alters proliferation, migration, and antioxidant capacity in human HTR8/SV-neo trophoblast cells. AB - Methylmercury, a potent neurotoxin, is able to pass through the placenta, but its effects on the placenta itself have not been elucidated. Using an immortalized human trophoblast cell line, HTR8/SV-neo, we assessed the in vitro toxicity of methylmercury. We found that 1 MUg/mL methylmercury decreased viability, proliferation, and migration; and it had effects on antioxidant genes similar to those seen in neural cells. However, methylmercury led to decreased expression of superoxide dismutase 1 and increased expression of surfactant protein D. HTR cells treated 0.01 or 0.1 MUg/mL methylmercury had increased migration rates along with decreased expression of an adhesion gene, cadherin 3, suggesting that low doses of methylmercury promote migration in HTR cells. Our results indicate that trophoblast cells react differently to methylmercury relative to neural cell lines, and thus investigation of methylmercury toxicity in placental cells is needed to understand the effects of this heavy metal on the placenta. PMID- 29581084 TI - Beyond the five-year horizon: long-term outcome of high-risk and inoperable patients undergoing TAVR with first-generation devices. AB - AIMS: We sought to determine the long-term outcome of high-risk patients who underwent transcatheter aortic valve replacement (TAVR) with first-generation devices with a focus on the identification of predictors for mortality and valve durability. METHODS AND RESULTS: Consecutive patients in our prospective single centre registry undergoing TAVR with first-generation devices (n=214 CoreValve; n=86 SAPIEN) between 06/2007 and 07/2009 were retrospectively analysed (n=300, mean age 81.43+/-6.55 years, mean STS score 6.5+/-4.5%). Kaplan-Meier estimates of survival and the Cox proportional hazards model were used to identify independent predictors of all-cause-mortality. At 1, 5, and 7 years, estimated survival rates were 76.0%, 40.2%, and 23.2%, respectively. Age-adjusted baseline predictors of mortality included atrial fibrillation, impaired kidney function, peripheral artery disease, and mitral regurgitation (>=moderate). Baseline risk adjusted procedure-related predictors for all-cause mortality included acute kidney injury, neurological events, major vascular complications, and major/life threatening bleeding. At both five and six years, 78.2% of surviving patients were in NYHA Class I or II. PVL was <=mild in the majority of patients at discharge and throughout follow-up. At seven years, the overall crude cumulative incidence of structural valve deterioration according to the 2017 EAPCI/ESC/EACTS definition was 14.9% (CoreValve 11.8% vs. SAPIEN 22.6%; p=0.01). CONCLUSIONS: Seven years after TAVR, 23.2% of high-risk patients were still alive. Independent predictors of all-cause mortality included both patient- and procedure-related factors. With a cumulative incidence of 14.9% at seven years, there is some suggestion that SVD post TAVR may become increasingly relevant during longer-term follow-up. PMID- 29581085 TI - Qualitative Resting Coronary Pressure Wave Form Analysis to Predict Fractional Flow Reserve. AB - AIMS: To evaluate the predictability of resting distal coronary pressure wave forms for fractional flow reserve (FFR). METHODS AND RESULTS: Resting coronary wave forms were qualitatively evaluated for the presence of (i) dicrotic notch; (ii) diastolic dipping; and (iii) ventricularization. In a development cohort (n=88) a scoring system was developed that was then applied to a validation cohort (n=428) using a multivariable linear regression model to predict FFR and receiver operating characteristics (ROC) to predict FFR <=0.8. In the development cohort, all 3 qualitative parameters were independent predictors of FFR. However, in a multivariable linear regression model in the validation cohort, qualitative wave form analysis did not further improve the ability of resting distal coronary to aortic pressure ratio (Pd/Pa) (p=0.80) or instantaneous wave-free ratio (iFR) (p=0.26) to predict FFR. Using ROC, the area under the curve of resting Pd/Pa (0.86 versus 0.86, P=0.08) and iFR (0.86 versus 0.86, P=0.26) did not improve by adding qualitative analysis. CONCLUSIONS: Qualitative coronary wave form analysis showed moderate classification agreement in predicting FFR but did not add substantially to the resting pressure gradients Pd/Pa and iFR; however, when discrepancies between quantitative and qualitative analyses are observed, artifact or pressure drift should be considered.

AB - BACKGROUND: Ostomy surgeries involving the placement of an ostomy bag (eg, colostomy, ileostomy, urostomy, etc) have been shown to have a negative impact on health-related quality of life. To date, no studies have been conducted examining what impact, if any, wearable biosensors have on the health-related quality of life of ostomy patients. OBJECTIVE: In the present study, we plan to assess the quality of life of ostomy patients using the Ostom-i alert sensor, a portable, wearable, Bluetooth-linked biosensor that facilitates easier ostomy bag output measurements. We hypothesize that using the Ostom-i alert sensor will result in an improved, ostomy-specific, health-related quality of life as compared to baseline measurement before the use of the sensor. METHODS: A total of 20 ostomy patients will be screened and recruited to participate in this prospective, observational, cross-over pilot study using an Ostom-i alert sensor for one month. The primary outcome of this study will compare ostomy-specific, health related quality of life at baseline (prior to Ostom-i alert sensor use) to ostomy specific, health-related quality of life after 2 and 4 weeks of Ostom-i use by utilizing the City of Hope Quality of Life Questionnaire for Patients with an Ostomy. Secondary outcomes of general health-related quality of life and adjustment to ostomy will be evaluated using the Medical Outcomes Study 36-item short form health survey and the Olbrisch Ostomy Adjustment Scale Short Form 2. RESULTS: The project was funded by the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University School of Medicine. Enrollment is currently underway and data analysis is expected to be completed in 2018. CONCLUSIONS: Proposed benefits of mobile, internet-linked personal health monitors, such as the Ostom-i, include a reduction in the cost of care by reducing resource utilization and infection rates, improving patient-provider communication, reducing time spent as an inpatient as well as improved quality of life. Prior studies have demonstrated decreased health-related quality of life in patients with an ostomy bag. We aim to examine the extent to which the Ostom-i alert sensor affects the health-related quality of life of its users. The Ostom-i alert sensor has the potential to improve quality of life of users by giving them the freedom and confidence to partake in daily activities with the knowledge that they can check how full their ostomy bag is in a private, discrete manner.

PMID- 29581088 TI - Effect of Harm Anchors in Visual Displays of Test Results on Patient Perceptions of Urgency About Near-Normal Values: Experimental Study. AB - BACKGROUND: Patient-facing displays of laboratory test results typically provide patients with one reference point (the "standard range"). OBJECTIVE: To test the effect of including an additional harm anchor reference point in visual displays of laboratory test results, which indicates how far outside of the standard range values would need to be in order to suggest substantial patient risk. METHODS: Using a demographically diverse, online sample, we compared the reactions of 1618 adults in the United States who viewed visual line displays that included both standard range and harm anchor reference points ("Many doctors are not concerned until here") to displays that included either (1) only a standard range, (2) standard range plus evaluative categories (eg, "borderline high"), or (3) a color gradient showing degree of deviation from the standard range. RESULTS: Providing the harm anchor reference point significantly reduced perceived urgency of close to-normal alanine aminotransferase and creatinine results (P values <.001) but not generally for platelet count results. Notably, display type did not significantly alter perceptions of more extreme results in potentially harmful ranges. Harm anchors also substantially reduced the number of participants who wanted to contact their doctor urgently or go to the hospital about these test results. CONCLUSIONS: Presenting patients with evaluative cues regarding when test results become clinically concerning can reduce the perceived urgency of out of-range results that do not require immediate clinical action. PMID- 29581089 TI - Evaluation of an Internet-Based Behavioral Intervention to Improve Psychosocial Health Outcomes in Children With Insomnia (Better Nights, Better Days): Protocol for a Randomized Controlled Trial. AB - BACKGROUND: Up to 25% of 1- to 10-year-old children experience insomnia (ie, resisting bedtime, trouble falling asleep, night awakenings, and waking too early in the morning). Insomnia can be associated with excessive daytime sleepiness and negative effects on daytime functioning across multiple domains (eg, behavior, mood, attention, and learning). Despite robust evidence supporting the effectiveness of behavioral treatments for insomnia in children, very few children with insomnia receive these treatments, primarily due to a shortage of available treatment resources. OBJECTIVE: The Better Nights, Better Days (BNBD) internet-based program provides a readily accessible electronic health (eHealth) intervention to support parents in providing evidence-based care for insomnia in typically developing children. The purpose of the randomized controlled trial (RCT) is to evaluate the effectiveness of BNBD in treating insomnia in children aged between 1 and 10 years. METHODS: BNBD is a fully automated program, developed based on evidence-based interventions previously tested by the investigators, as well as on the extant literature on this topic. We describe the 2-arm RCT in which participants (500 primary caregivers of children with insomnia residing in Canada) are assigned to intervention or usual care. RESULTS: The effects of this behavioral sleep eHealth intervention will be assessed at 4 and 8 months postrandomization. Assessment includes both sleep (actigraphy, sleep diary) and daytime functioning of the children and daytime functioning of their parents. Results will be reported using the standards set out in the Consolidated Standards of Reporting Trials statement. CONCLUSIONS: If the intervention is supported by the results of the RCT, we plan to commercialize this program so that it is sustainable and available at a low cost to all families with internet access.

PMID- 29581090 TI - Implications of Patient Portal Transparency in Oncology: Qualitative Interview Study on the Experiences of Patients, Oncologists, and Medical Informaticists. AB - BACKGROUND: Providing patients with unrestricted access to their electronic medical records through patient portals has impacted patient-provider communication and patients' personal health knowledge. However, little is known about how patient portals are used in oncology. OBJECTIVE: The aim of this study was to understand attitudes of the portal's adoption for oncology and to identify the advantages and disadvantages of using the portal to communicate and view medical information. METHODS: In-depth semistructured interviews were conducted with 60 participants: 35 patients, 13 oncologists, and 12 medical informaticists. Interviews were recorded, transcribed, and thematically analyzed to identify critical incidents and general attitudes encountered by participants. RESULTS: Two primary themes were discovered: (1) implementation practices influence attitudes, in which the decision-making and execution process of introducing portals throughout the hospital did not include the input of oncologists. Lack of oncologists' involvement led to a lack of knowledge about portal functionality, such as not knowing the time period when test results would be disclosed to patients; (2) perceptions of portals as communication tools varies by user type, meaning that each participant group (patients, oncologists, and medical informaticists) had varied opinions about how the portal should be used to transmit and receive information. Oncologists and medical informaticists had difficulty understanding one another's culture and communication processes in their fields, while patients had preferences for how they would like to receive communication, but it largely depended upon the type of test being disclosed. CONCLUSIONS: The majority of patients (54%, 19/35) who participated in this study viewed lab results or scan reports via the portal before being contacted by a clinician. Most were relatively comfortable with this manner of disclosure but still preferred face-to-face or telephone communication. Findings from this study indicate that portal education is needed for both patients and oncologists, especially when portals are implemented across entire health systems since highly specialized areas of medicine may have unique needs and uses. Patient portals in oncology can potentially alter the way diagnoses are delivered and how patients and oncologists communicate. Therefore, communication about the portal should be established during initial consultations so patients can decide whether they want to be informed in such a manner. PMID- 29581091 TI - How Online Quality Ratings Influence Patients' Choice of Medical Providers: Controlled Experimental Survey Study. AB - BACKGROUND: In recent years, the information environment for patients to learn about physician quality is being rapidly changed by Web-based ratings from both commercial and government efforts. However, little is known about how various types of Web-based ratings affect individuals' choice of physicians. OBJECTIVE: The objective of this research was to measure the relative importance of Web based quality ratings from governmental and commercial agencies on individuals' choice of primary care physicians. METHODS: In a choice-based conjoint experiment conducted on a sample of 1000 Amazon Mechanical Turk users in October 2016, individuals were asked to choose their preferred primary care physician from pairs of physicians with different ratings in clinical and nonclinical aspects of care provided by governmental and commercial agencies. RESULTS: The relative log odds of choosing a physician increases by 1.31 (95% CI 1.26-1.37; P<.001) and 1.32 (95% CI 1.27-1.39; P<.001) units when the government clinical ratings and commercial nonclinical ratings move from 2 to 4 stars, respectively. The relative log odds of choosing a physician increases by 1.12 (95% CI 1.07-1.18; P<.001) units when the commercial clinical ratings move from 2 to 4 stars. The relative log odds of selecting a physician with 4 stars in nonclinical ratings provided by the government is 1.03 (95% CI 0.98-1.09; P<.001) units higher than a physician with 2 stars in this rating. The log odds of selecting a physician with 4 stars in nonclinical government ratings relative to a physician with 2 stars is 0.23 (95% CI 0.13-0.33; P<.001) units higher for females compared with males. Similar star increase in nonclinical commercial ratings increases the relative log odds of selecting the physician by female respondents by 0.15 (95% CI 0.04-0.26; P=.006) units. CONCLUSIONS: Individuals perceive nonclinical ratings provided by commercial websites as important as clinical ratings provided by government websites when choosing a primary care physician. There are significant gender differences in how the ratings are used. More research is needed on whether patients are making the best use of different types of ratings, as well as the optimal allocation of resources in improving physician ratings from the government's perspective. PMID- 29581092 TI - Detecting Motor Impairment in Early Parkinson's Disease via Natural Typing Interaction With Keyboards: Validation of the neuroQWERTY Approach in an Uncontrolled At-Home Setting. AB - BACKGROUND: Parkinson's disease (PD) is the second most prevalent neurodegenerative disease and one of the most common forms of movement disorder. Although there is no known cure for PD, existing therapies can provide effective symptomatic relief. However, optimal titration is crucial to avoid adverse effects. Today, decision making for PD management is challenging because it relies on subjective clinical evaluations that require a visit to the clinic. This challenge has motivated recent research initiatives to develop tools that can be used by nonspecialists to assess psychomotor impairment. Among these emerging solutions, we recently reported the neuroQWERTY index, a new digital marker able to detect motor impairment in an early PD cohort through the analysis of the key press and release timing data collected during a controlled in-clinic typing task. OBJECTIVE: The aim of this study was to extend the in-clinic implementation to an at-home implementation by validating the applicability of the neuroQWERTY approach in an uncontrolled at-home setting, using the typing data from subjects' natural interaction with their laptop to enable remote and unobtrusive assessment of PD signs. METHODS: We implemented the data-collection platform and software to enable access and storage of the typing data generated by users while using their computer at home. We recruited a total of 60 participants; of these participants 52 (25 people with Parkinson's and 27 healthy controls) provided enough data to complete the analysis. Finally, to evaluate whether our in-clinic-built algorithm could be used in an uncontrolled at-home setting, we compared its performance on the data collected during the controlled typing task in the clinic and the results of our method using the data passively collected at home. RESULTS: Despite the randomness and sparsity introduced by the uncontrolled setting, our algorithm performed nearly as well in the at-home data (area under the receiver operating characteristic curve [AUC] of 0.76 and sensitivity/specificity of 0.73/0.69) as it did when used to evaluate the in clinic data (AUC 0.83 and sensitivity/specificity of 0.77/0.72). Moreover, the keystroke metrics presented a strong correlation between the 2 typing settings, which suggests a minimal influence of the in-clinic typing task in users' normal typing. CONCLUSIONS: The finding that an algorithm trained on data from an in clinic setting has comparable performance with that tested on data collected through naturalistic at-home computer use reinforces the hypothesis that subtle differences in motor function can be detected from typing behavior. This work represents another step toward an objective, user-convenient, and quasi continuous monitoring tool for PD. PMID- 29581093 TI - Evolution of Cognitive Rehabilitation After Stroke From Traditional Techniques to Smart and Personalized Home-Based Information and Communication Technology Systems: Literature Review. AB - BACKGROUND: Neurological patients after stroke usually present cognitive deficits that cause dependencies in their daily living. These deficits mainly affect the performance of some of their daily activities. For that reason, stroke patients need long-term processes for their cognitive rehabilitation. Considering that classical techniques are focused on acting as guides and are dependent on help from therapists, significant efforts are being made to improve current methodologies and to use eHealth and Web-based architectures to implement information and communication technology (ICT) systems that achieve reliable, personalized, and home-based platforms to increase efficiency and level of attractiveness for patients and carers. OBJECTIVE: The goal of this work was to provide an overview of the practices implemented for the assessment of stroke patients and cognitive rehabilitation. This study puts together traditional methods and the most recent personalized platforms based on ICT technologies and Internet of Things. METHODS: A literature review has been distributed to a multidisciplinary team of researchers from engineering, psychology, and sport science fields. The systematic review has been focused on published scientific research, other European projects, and the most current innovative large-scale initiatives in the area. A total of 3469 results were retrieved from Web of Science, 284 studies from Journal of Medical Internet Research, and 15 European research projects from Community Research and Development Information Service from the last 15 years were reviewed for classification and selection regarding their relevance. RESULTS: A total of 7 relevant studies on the screening of stroke patients have been presented with 6 additional methods for the analysis of kinematics and 9 studies on the execution of goal-oriented activities. Meanwhile, the classical methods to provide cognitive rehabilitation have been classified in the 5 main techniques implemented. Finally, the review has been finalized with the selection of 8 different ICT-based approaches found in scientific-technical studies, 9 European projects funded by the European Commission that offer eHealth architectures, and other large-scale activities such as smart houses and the initiative City4Age. CONCLUSIONS: Stroke is one of the main causes that most negatively affect countries in the socioeconomic aspect. The design of new ICT based systems should provide 4 main features for an efficient and personalized cognitive rehabilitation: support in the execution of complex daily tasks, automatic error detection, home-based performance, and accessibility. Only 33% of the European projects presented fulfilled those requirements at the same time. For this reason, current and future large-scale initiatives focused on eHealth and smart environments should try to solve this situation by providing more complete and sophisticated platforms. PMID- 29581094 TI - Prenatal Remote Monitoring of Women With Gestational Hypertensive Diseases: Cost Analysis. AB - BACKGROUND: Remote monitoring in obstetrics is relatively new; some studies have shown its effectiveness for both mother and child. However, few studies have evaluated the economic impact compared to conventional care, and no cost analysis of a remote monitoring prenatal follow-up program for women diagnosed with gestational hypertensive diseases (GHD) has been published. OBJECTIVE: The aim of this study was to assess the costs of remote monitoring versus conventional care relative to reported benefits. METHODS: Patient data from the Pregnancy Remote Monitoring (PREMOM) study were used. Health care costs were calculated from patient-specific hospital bills of Ziekenhuis Oost-Limburg (Genk, Belgium) in 2015. Cost comparison was made from three perspectives: the Belgian national health care system (HCS), the National Institution for Insurance of Disease and Disability (RIZIV), and costs for individual patients. The calculations were made for four major domains: prenatal follow-up, prenatal admission to the hospital, maternal and neonatal care at and after delivery, and total amount of costs. A simulation exercise was made in which it was calculated how much could be demanded of RIZIV for funding the remote monitoring service. RESULTS: A total of 140 pregnancies were included, of which 43 received remote monitoring (30.7%) and 97 received conventional care (69.2%). From the three perspectives, there were no differences in costs for prenatal follow-up. Compared to conventional care, remote monitoring patients had 34.51% less HCS and 41.72% less RIZIV costs for laboratory test results (HCS: mean ?0.00 [SD ?55.34] vs mean ?38.28 [SD ? 44.08], P<.001; RIZIV: mean ?21.09 [SD ?27.94] vs mean ?36.19 [SD ?41.36], P<.001) and a reduction of 47.16% in HCS and 48.19% in RIZIV costs for neonatal care (HCS: mean ?989.66 [SD ?3020.22] vs mean ?1872.92 [SD ?5058.31], P<.001; RIZIV: mean ?872.97 [SD ?2761.64] vs mean ?1684.86 [SD ?4702.20], P<.001). HCS costs for medication were 1.92% lower in remote monitoring than conventional care (mean ?209.22 [SD ?213.32] vs mean ?231.32 [SD 67.09], P=.02), but were 0.69% higher for RIZIV (mean ?122.60 [SD ?92.02] vs mean ?121.78 [SD ?20.77], P<.001). Overall HCS costs for remote monitoring were mean ?4233.31 (SD ?3463.31) per person and mean ?4973.69 (SD ?5219.00) per person for conventional care (P=.82), a reduction of ?740.38 (14.89%) per person, with savings mainly for RIZIV of ?848.97 per person (23.18%; mean ?2797.42 [SD ?2905.18] vs mean ?3646.39 [SD ?4878.47], P=.19). When an additional fee of ?525.07 per month per pregnant woman for funding remote monitoring costs is demanded, remote monitoring is acceptable in their costs for HCS, RIZIV, and individual patients. CONCLUSIONS: In the current organization of Belgian health care, a remote monitoring prenatal follow-up of women with GHD is cost saving for the global health care system, mainly via savings for the insurance institution RIZIV. PMID- 29581095 TI - The Presence of Diabetes and Higher HbA1c Are Independently Associated With Adverse Outcomes After Surgery. AB - OBJECTIVE: Limited studies have examined the association between diabetes and HbA1c with postoperative outcomes. We investigated the association of diabetes, defined categorically, and the association of HbA1c as a continuous measure, with postoperative outcomes. RESEARCH DESIGN AND METHODS: In this prospective, observational study, we measured the HbA1c of surgical inpatients age >=54 years at a tertiary hospital between May 2013 and January 2016. Patients were diagnosed with diabetes if they had preexisting diabetes or an HbA1c >=6.5% (48 mmol/mol) or with prediabetes if they had an HbA1c between 5.7 and 6.4% (39 and 48 mmol/mol). Patients with an HbA1c <5.7% (39 mmol/mol) were categorized as having normoglycemia. Baseline demographic and clinical data were obtained from hospital records, and patients were followed for 6 months. Random-effects logistic and negative binomial regression models were used for analysis, treating surgical units as random effects. We undertook classification and regression tree (CART) analysis to design a 6-month mortality risk model. RESULTS: Of 7,565 inpatients, 30% had diabetes, and 37% had prediabetes. After adjusting for age, Charlson comorbidity index (excluding diabetes and age), estimated glomerular filtration rate, and length of surgery, diabetes was associated with increased 6-month mortality (adjusted odds ratio [aOR] 1.29 [95% CI 1.05-1.58]; P = 0.014), major complications (1.32 [1.14-1.52]; P < 0.001), intensive care unit (ICU) admission (1.50 [1.28-1.75]; P < 0.001), mechanical ventilation (1.67 [1.32-2.10]; P < 0.001), and hospital length of stay (LOS) (adjusted incidence rate ratio [aIRR] 1.08 [95% CI 1.04-1.12]; P < 0.001). Each percentage increase in HbA1c was associated with increased major complications (aOR 1.07 [1.01-1.14]; P = 0.030), ICU admission (aOR 1.14 [1.07-1.21]; P < 0.001), and hospital LOS (aIRR 1.05 [1.03-1.06]; P < 0.001). CART analysis confirmed a higher risk of 6-month mortality with diabetes in conjunction with other risk factors. CONCLUSIONS: Almost one-third of surgical inpatients age >=54 years had diabetes. Diabetes and higher HbA1c were independently associated with a higher risk of adverse outcomes after surgery. PMID- 29581096 TI - p110alpha of PI3K is necessary and sufficient for quiescence exit in adult muscle satellite cells. AB - Adult mouse muscle satellite cells (MuSCs) are quiescent in uninjured muscles. Upon injury, MuSCs exit quiescence in vivo to become activated, re-enter the cell cycle to proliferate, and differentiate to repair the damaged muscles. It remains unclear which extrinsic cues and intrinsic signaling pathways regulate quiescence exit during MuSC activation. Here, we demonstrated that inducible MuSC-specific deletion of p110alpha, a catalytic subunit of phosphatidylinositol 3-kinase (PI3K), rendered MuSCs unable to exit quiescence, resulting in severely impaired MuSC proliferation and muscle regeneration. Genetic reactivation of mTORC1, or knockdown of FoxOs, in p110alpha-null MuSCs partially rescued the above defects, making them key effectors downstream of PI3K in regulating quiescence exit. c-Jun was found to be a key transcriptional target of the PI3K/mTORC1 signaling axis essential for MuSC quiescence exit. Moreover, induction of a constitutively active PI3K in quiescent MuSCs resulted in spontaneous MuSC activation in uninjured muscles and subsequent depletion of the MuSC pool. Thus, PI3K-p110alpha is both necessary and sufficient for MuSCs to exit quiescence in response to activating signals. PMID- 29581097 TI - Spatial separation between replisome- and template-induced replication stress signaling. AB - Polymerase-blocking DNA lesions are thought to elicit a checkpoint response via accumulation of single-stranded DNA at stalled replication forks. However, as an alternative to persistent fork stalling, re-priming downstream of lesions can give rise to daughter-strand gaps behind replication forks. We show here that the processing of such structures by an exonuclease, Exo1, is required for timely checkpoint activation, which in turn prevents further gap erosion in S phase. This Rad9-dependent mechanism of damage signaling is distinct from the Mrc1 dependent, fork-associated response to replication stress induced by conditions such as nucleotide depletion or replisome-inherent problems, but reminiscent of replication-independent checkpoint activation by single-stranded DNA Our results indicate that while replisome stalling triggers a checkpoint response directly at the stalled replication fork, the response to replication stress elicited by polymerase-blocking lesions mainly emanates from Exo1-processed, postreplicative daughter-strand gaps, thus offering a mechanistic explanation for the dichotomy between replisome- versus template-induced checkpoint signaling.

PMID- 29581100 TI - Resilience: surviving and thriving in the paediatric workplace. AB - The health of the medical workforce, within the UK, has been described as an unmet public health need. Reports of stress, burnout and ill health are continuing to rise. Burnout is when meaningful and challenging work becomes unpleasant and unfulfilling; energy turns into exhaustion; enthusiasm turns into cynicism and efficacy turns into ineffectiveness. Stress is an individual's physical and psychological response to single or multiple pressures. Low-level stress, or 'healthy stress', is essential. Stress becomes unhealthy when pressures exceed one's perceived ability to cope and the response to the pressures becomes counterproductive, leading to a decrease in performance. Resilience is the capability to develop and adapt to challenges and discover new ways forward, without negative consequences on one's well-being. This paper discusses stress and burnout within the healthcare profession; strategies to cope with the demands of the workplace through a reflective scenario, along with well being and mindfulness resources for managing stress and promoting resilience. The five ways to well-being and mindfulness practice are simple measures that can be built into one's daily life to increase resilience against excess stress and pressures. The coping matrix is a practical tool to encourage reflecting upon and developing one's own coping strategies. A good healthcare professional is one who is compassionate to themselves and their own well-being, enabling them to care and treat their patients. PMID- 29581101 TI - Catastrophic drug coverage: utilization insights from the Ontario Trillium Drug Program. AB - BACKGROUND: Catastrophic drug coverage programs help those with high drug-costs to reduce the burden of out-of-pocket expenses. We set out to measure changes in utilization, spending and demographic profiles of people accessing Ontario's catastrophic drug program, the Trillium Drug Program. METHODS: We conducted a cross-sectional time-series analysis examining quarterly utilization and spending trends among medications reimbursed by the Trillium Drug Program in Ontario, Canada from Jan. 1, 2000, to Dec. 31, 2016. In each of 2000, 2005, 2010 and 2015, we described the population of beneficiaries, including demographic information, health care utilization and medication utilization. RESULTS: Over our study period, use of the Trillium Drug Program increased threefold from 3.6 beneficiaries per 1000 to 10.9 beneficiaries per 1000 Ontarians, and total government spending on the program increased by over 700%, reaching $487 million in 2016. Between 2000 and 2015, there was an increase in the number of beneficiaries who were under the age of 35 years (19.6% to 25.3%; p < 0.0001), did not have a hospital admission (68.3% to 80.5%; p < 0.0001) and had medium to high deductibles (2.3% to 8.0%; p < 0.0001). Further, there was a large increase in the percentage of users with drug claims greater than $1000 (3.4% to 10.4%; p < 0.0001) and those dispensed a high-cost biologic drug (1.6% to 5.5%; p < 0.0001). INTERPRETATION: Increasing use of Ontario's catastrophic drug program highlights the growing burden of high drug prices for Canadians. With a growing number of expensive drugs being approved in Canada, we anticipate that spending and use of the catastrophic drug program will continue to expand.

PMID- 29581103 TI - Data Generated by Quantitative Liquid Chromatography-Mass Spectrometry Proteomics Are Only the Start and Not the Endpoint: Optimization of Quantitative Concatemer Based Measurement of Hepatic Uridine-5'-Diphosphate-Glucuronosyltransferase Enzymes with Reference to Catalytic Activity. AB - Quantitative proteomic methods require optimization at several stages, including sample preparation, liquid chromatography-tandem mass spectrometry (LC-MS/MS), and data analysis, with the final analysis stage being less widely appreciated by end-users. Previously reported measurement of eight uridine-5'-diphospho glucuronosyltransferases (UGT) generated by two laboratories [using stable isotope-labeled (SIL) peptides or quantitative concatemer (QconCAT)] reflected significant disparity between proteomic methods. Initial analysis of QconCAT data showed lack of correlation with catalytic activity for several UGTs (1A4, 1A6, 1A9, 2B15) and moderate correlations for UGTs 1A1, 1A3, and 2B7 (Rs = 0.40-0.79, P < 0.05; R2 = 0.30); good correlations were demonstrated between cytochrome P450 activities and abundances measured in the same experiments. Consequently, a systematic review of data analysis, starting from unprocessed LC-MS/MS data, was undertaken, with the aim of improving accuracy, defined by correlation against activity. Three main criteria were found to be important: choice of monitored peptides and fragments, correction for isotope-label incorporation, and abundance normalization using fractional protein mass. Upon optimization, abundance activity correlations improved significantly for six UGTs (Rs = 0.53-0.87, P < 0.01; R2 = 0.48-0.73); UGT1A9 showed moderate correlation (Rs = 0.47, P = 0.02; R2 = 0.34). No spurious abundance-activity relationships were identified. However, methods remained suboptimal for UGT1A3 and UGT1A9; here hydrophobicity of standard peptides is believed to be limiting. This commentary provides a detailed data analysis strategy and indicates, using examples, the significance of systematic data processing following acquisition. The proposed strategy offers significant improvement on existing guidelines applicable to clinically relevant proteins quantified using QconCAT.

PMID- 29581106 TI - What Else Can We Do to Ensure Transplant Equity for High-Risk Patients? PMID- 29581107 TI - Transplant Center Patient Navigator and Access to Transplantation among High-Risk Population: A Randomized, Controlled Trial. AB - BACKGROUND AND OBJECTIVES: Barriers exist in access to kidney transplantation, where minority and patients with low socioeconomic status are less likely to complete transplant evaluation. The purpose of this study was to examine the effectiveness of a transplant center-based patient navigator in helping patients at high risk of dropping out of the transplant evaluation process access the kidney transplant waiting list. DESIGN, SETTING, PARTICIPANTS & MEASUREMENTS: We conducted a randomized, controlled trial of 401 patients (n=196 intervention and n=205 control) referred for kidney transplant evaluation (January 2013 to August 2014; followed through May 2016) at a single center. A trained navigator assisted intervention participants from referral to waitlisting decision to increase waitlisting (primary outcome) and decrease time from referral to waitlisting (secondary outcome). Time-dependent Cox proportional hazards models were used to determine differences in waitlisting between intervention and control patients. RESULTS: At study end, waitlisting was not significantly different among intervention (32%) versus control (26%) patients overall (P=0.17), and time from referral to waitlisting was 126 days longer for intervention patients. However, the effectiveness of the navigator varied from early (<500 days from referral) to late (>=500 days) follow-up. Although no difference in waitlisting was observed among intervention (50%) versus control (50%) patients in the early period (hazard ratio, 1.03; 95% confidence interval, 0.69 to 1.53), intervention patients were 3.3 times more likely to be waitlisted after 500 days (75% versus 25%; hazard ratio, 3.31; 95% confidence interval, 1.20 to 9.12). There were no significant differences in intervention versus control patients who started evaluation (85% versus 79%; P=0.11) or completed evaluation (58% versus 51%; P=0.14); however, intervention patients had more living donor inquiries (18% versus 10%; P=0.03). CONCLUSIONS: A transplant center-based navigator targeting disadvantaged patients improved waitlisting but not until after 500 days of follow-up. However, the absolute effect was relatively small. PMID- 29581108 TI - VKORC1 and VKORC1L1 have distinctly different oral anticoagulant dose-response characteristics and binding sites. AB - Vitamin K reduction is catalyzed by 2 enzymes in vitro: the vitamin K 2,3-epoxide reductase complex subunit 1 (VKORC1) and its isozyme VKORC1-like1 (VKORC1L1). In vivo, VKORC1 reduces vitamin K to sustain gamma-carboxylation of vitamin K dependent proteins, including coagulation factors. Inhibition of VKORC1 by oral anticoagulants (OACs) is clinically used in therapy and in prevention of thrombosis. However, OACs also inhibit VKORC1L1, which was previously shown to play a role in intracellular redox homeostasis in vitro. Here, we report data for the first time on specific inhibition of both VKOR enzymes for various OACs and rodenticides examined in a cell-based assay. Effects on endogenous VKORC1 and VKORC1L1 were independently investigated in genetically engineered HEK 293T cells that were knocked out for the respective genes by CRISPR/Cas9 technology. In general, dose-responses for 4-hydroxycoumarins and 1,3-indandiones were enzyme dependent, with lower susceptibility for VKORC1L1 compared with VKORC1. In contrast, rodenticides exhibited nearly identical dose-responses for both enzymes. To explain the distinct inhibition pattern, we performed in silico modeling suggesting different warfarin binding sites for VKORC1 and VKORC1L1. We identified arginine residues at positions 38, 42, and 68 in the endoplasmatic reticulum luminal loop of VKORC1L1 responsible for charge-stabilized warfarin binding, resulting in a binding pocket that is diametrically opposite to that of VKORC1. In conclusion, our findings provide insight into structural and molecular drug binding on VKORC1, and especially on VKORC1L1. PMID- 29581109 TI - B-cell tumor development in Tet2-deficient mice. AB - The TET2 gene encodes an alpha-ketoglutarate-dependent dioxygenase able to oxidize 5-methylcytosine into 5-hydroxymethylcytosine, which is a step toward active DNA demethylation. TET2 is frequently mutated in myeloid malignancies but also in B- and T-cell malignancies. TET2 somatic mutations are also identified in healthy elderly individuals with clonal hematopoiesis. Tet2-deficient mouse models showed widespread hematological differentiation abnormalities, including myeloid, T-cell, and B-cell malignancies. We show here that, similar to what is observed with constitutive Tet2-deficient mice, B-cell-specific Tet2 knockout leads to abnormalities in the B1-cell subset and a development of B-cell malignancies after long latency. Aging Tet2-deficient mice accumulate clonal CD19+ B220low immunoglobulin M+ B-cell populations with transplantable ability showing similarities to human chronic lymphocytic leukemia, including CD5 expression and sensitivity to ibrutinib-mediated B-cell receptor (BCR) signaling inhibition. Exome sequencing of Tet2-/- malignant B cells reveals C-to-T and G-to A mutations that lie within single-stranded DNA-specific activation-induced deaminase (AID)/APOBEC (apolipoprotein B messenger RNA editing enzyme, catalytic polypeptide-like) cytidine deaminases targeted motif, as confirmed by the lack of a B-cell tumor in compound Tet2-Aicda-deficient mice. Finally, we show that Tet2 deficiency accelerates and exacerbates T-cell leukemia/lymphoma 1A-induced leukemogenesis. Together, our data establish that Tet2 deficiency predisposes to mature B-cell malignancies, which development might be attributed in part to AID mediated accumulating mutations and BCR-mediated signaling.

AB - Among 158 Candida glabrata bloodstream isolates collected from numerous centers in China, a resistance to fluconazole was seen in 8.9%. Three isolates (1.9%) were resistant to all echinocandins. Multilocus sequence typing (MLST) revealed that sequence type 7 ([ST7] 65.8%) was the most common type, followed by ST3 (7.6%). PDR1 polymorphisms were associated with the acquisition of fluconazole resistance in C. glabrata isolates, while MSH2 polymorphisms were associated with the STs and microsatellite genotypes, irrespective of fluconazole resistance. PMID- 29581111 TI - Combination of Amphotericin B and Terbinafine against Melanized Fungi Associated with Chromoblastomycosis. AB - Our in vitro studies showed that a combination of amphotericin B and terbinafine had synergistic effects against the majority of melanized fungi associated with chromoblastomycosis (CBM) and similar infections, including those with Cladophialophora carrionii, Cladophialophora arxii, Exophialadermatitidis, Exophialaspinifera, Fonsecaea monophora, Fonsecaea nubica, Fonsecaea pedrosoi, and Phialophora verrucosa. This drug combination could provide an option for the treatment of severe or unresponsive cases of CBM, particularly in cases due to species of Fonsecaea and Cladophialophora. PMID- 29581112 TI - Survival in Patients with Candida glabrata Bloodstream Infection Is Associated with Fluconazole Dose. AB - Robust pharmacodynamic indices that align fluconazole dose or exposure with outcomes in invasive candidiasis due to Candida glabrata remain elusive. The purpose of this retrospective multicenter study was to evaluate a cohort of 127 patients with C. glabrata fungemia treated with fluconazole, using adjusted analyses to identify risk factors for 28-day death. No significant correlations were found between fluconazole area under the curve (AUC), AUC/MIC ratio, or MIC and survival. In multivariate logistic regression analyses, however, higher average fluconazole dose (odds ratio [OR], 1.006 [95% confidence interval [CI], 1.001 to 1.010]; P = 0.008), average fluconazole dose of >=400 mg (OR, 3.965 [95% CI, 1.509 to 10.418]; P = 0.005), and higher fluconazole dose on day 1 of therapy (OR, 1.007 [95% CI, 1.002 to 1.011]; P = 0.002) were found to be independent predictors of 28-day survival. Additionally, the presence of a central venous catheter at the time of infection was found to be a significant risk factor for death. In conclusion, we found fluconazole dose to be an independent predictor of 28-day survival for patients with C. glabrata fungemia, with doses of >=400 mg/day being associated with 28-day survival rates approaching 90%. These data indicate the use and efficacy of fluconazole in the treatment of this serious infection. Aggressive dosing appears to be necessary when fluconazole is used for the treatment of C. glabrata fungemia, irrespective of MIC. PMID- 29581113 TI - Chemotherapy with Phage Lysins Reduces Pneumococcal Colonization of the Respiratory Tract. AB - Bacteriophage-borne lytic enzymes, also named lysins or enzybiotics, are efficient agents for the killing of bacterial pathogens. The colonization of the respiratory tract by Streptococcus pneumoniae is a prerequisite for the establishment of the infection process. Hence, we have evaluated the antibacterial activities of three different lysins against pneumococcal colonization using human nasopharyngeal and lung epithelial cells as well as a mouse model of nasopharyngeal colonization. The lysins tested were the wild-type Cpl-1, the engineered Cpl-7S, and the chimera Cpl-711. Moreover, we included amoxicillin as a comparator antibiotic. Human epithelial cells were infected with three different multidrug-resistant clinical isolates of S. pneumoniae followed by a single dose of the corresponding lysin. The antimicrobial activities of these lysins were also evaluated using a mouse nasopharyngeal carriage model. The exposure of the infected epithelial cells to Cpl-7S did not result in the killing of any of the pneumococcal strains investigated. However, the treatment with Cpl 1 or Cpl-711 increased the killing of S. pneumoniae organisms adhered to both types of human epithelial cells, with Cpl-711 being more effective than Cpl-1, at subinhibitory concentrations. In addition, a treatment with amoxicillin had no effect on reducing the carrier state, whereas mice treated by the intranasal route with Cpl-711 showed significantly reduced nasopharyngeal colonization, with no detection of bacterial load in 20 to 40% of the mice. This study indicates that Cpl-1 and Cpl-711 lysins might be promising antimicrobial candidates for therapy against pneumococcal colonization. PMID- 29581114 TI - Determination of the Dynamically Linked Indices of Fosfomycin for Pseudomonas aeruginosa in the Hollow Fiber Infection Model. AB - Fosfomycin is the only expoxide antimicrobial and is currently under development in the United States as an intravenously administered product. We were interested in identifying the exposure indices most closely linked to its ability to kill bacterial cells and to suppress amplification of less susceptible subpopulations. We employed the hollow fiber infection model for this investigation and studied wild-type strain Pseudomonas aeruginosa PAO1. Because of anticipated rapid resistance emergence, we shortened the study duration to 24 h but sampled the system more intensively. Doses of 12 and 18 g/day and schedules of daily administration, administration every 8 h, and administration by continuous infusion for each daily dose were studied. We measured fosfomycin concentrations (by liquid chromatography-tandem mass spectrometry), the total bacterial burden, and the burden of less susceptible isolates. We applied a mathematical model to all the data simultaneously. There was a rapid emergence of resistance with all doses and schedules. Prior to resistance emergence, an initial kill of 2 to 3 log10(CFU/ml) was observed. The model demonstrated that the area under the concentration-time curve/MIC ratio was linked to total bacterial kill, while the time that the concentration remained above the MIC (or, equivalently, the minimum concentration/MIC ratio) was linked to resistance suppression. These findings were also seen in other investigations with Enterobacteriaceae (in vitro systems) and P. aeruginosa (murine system). We conclude that for serious infections with high bacterial burdens, fosfomycin may be of value as a new therapeutic and may be optimized by administering the agent as a continuous or prolonged infusion or by use of a short dosing interval. For indications such as ventilator-associated bacterial pneumonia, it may be prudent to administer fosfomycin as part of a combination regimen. PMID- 29581115 TI - Clinical and Microbiological Characteristics of Candida guilliermondii and Candida fermentati. AB - A total of 46 clinical isolates of Candida guilliermondii and Candida famata were reidentified genetically, resulting in 27 C. guilliermondii and 12 Candida fermentati strains. The majority of C. guilliermondii strains, but not C. fermentati strains, were isolated from blood cultures. C. fermentati was more sensitive to antifungals, hydrogen peroxide, and killing by murine macrophages than was C. guilliermondii The C. guilliermondii isolates were echinocandin susceptible in vitro but resistant to micafungin in a murine model of invasive candidiasis. PMID- 29581116 TI - Antifungal Prophylaxis with Posaconazole Delayed-Release Tablet and Oral Suspension in a Real-Life Setting: Plasma Levels, Efficacy, and Tolerability. AB - We continuously determined posaconazole plasma concentrations (PPCs) in 61 patients with hematological malignancies receiving posaconazole (PCZ) delayed release tablets (DRT; 48 patients; median duration of intake, 92 days) and PCZ oral solution (OS; 13 patients; median duration of intake, 124 days). PCZ DRT and OS antifungal prophylaxis was efficient and well tolerated. Thirty-four of 48 patients (71%) receiving DRT always had PPCs of >0.7 mg/liter, while 14 of 48 patients (29%) had at least one PPC of <=0.7 mg/liter. In patients receiving OS, 4 of 13 patients (31%) always had PPCs of >0.7 mg/liter, 6 of 13 patients (46%) had at least one PPC of <=0.7 mg/liter, and 3 (23%) patients never reached a PPC of 0.7 mg/liter. In patients with at least one determined PPC, the mean proportion of all PPCs of >0.7 mg/liter was 91% for PCZ DRT, whereas it was 52% for PCZ OS (P = 0.001). In the per sample analysis, PPCs were significantly more likely to be >0.7 mg/liter in patients receiving DRT than in patients receiving OS (PPCs were >0.7 mg/liter in 91.4% [297/325] of patients receiving DRT versus 70.3% [85/121] of patients receiving OS; P < 0.001). Patients receiving PCZ DRT had higher proportions of PPCs of >0.7 mg/liter than patients receiving OS both in the per patient and in the per sample analyses. Two patients (3%) had side effects during PCZ prophylaxis, and one (2%) had fungal breakthrough infection. Therapeutic drug monitoring enables detection of extended periods of PPCs of <=0.7 mg/liter (e.g., due to nonadherence or graft-versus-host disease), which may also be associated with the loss of protective intracellular PCZ concentrations, regardless of the PCZ formulation. PMID- 29581117 TI - Pharmacokinetics and Pharmacodynamics of Fosfomycin and Its Activity against Extended-Spectrum-beta-Lactamase-, Plasmid-Mediated AmpC-, and Carbapenemase Producing Escherichia coli in a Murine Urinary Tract Infection Model. AB - Fosfomycin has become an attractive treatment alternative for urinary tract infections (UTIs) due to increasing multidrug resistance (MDR) in Escherichia coli In this study, we evaluated the pharmacokinetic (PK) and pharmacodynamic (PD) indices of fosfomycin and its in vivo activity in an experimental murine model of ascending UTI. Subcutaneous administration of fosfomycin showed that the mean peak plasma concentrations of fosfomycin were 36, 280, and 750 mg/liter following administration of a single dose of 0.75, 7.5, and 30 mg/mouse, respectively, with an elimination half-life of 28 min, and urine peak concentrations of 1,100, 33,400, and 70,000 mg/liter expected to be sustained above 1 mg/liter (MIC of the test strain, NU14) for 5, 8, and 9.5 h, respectively. The optimal PK/PD indices for reducing urine colony counts (number of CFU per milliliter) were determined to be the area under the concentration time curve/MIC from 0 to 72 h and the maximum concentration/MIC on the basis of the dose-dependent bloodstream PK and the results of an evaluation of six dosing regimens. With a dosing regimen of 15 mg/mouse twice (every 36 h), fosfomycin significantly reduced the number of CFU per milliliter of all susceptible strains in urine, including clinical MDR strains, except for one clinical strain (P = 0.062). Variable degrees of reduction were observed in the bladder and kidneys. No significant reductions in the number of CFU per milliliter were observed with the resistant strains. In conclusion, fosfomycin shows concentration-dependent in vivo activity, and the results suggest that fosfomycin is an effective alternative to carbapenems in treating MDR E. coli in uncomplicated UTIs. The data on the effectiveness of fosfomycin against the MDR isolates along with the results of PK/PD modeling should facilitate the further development of improved recommendations for its clinical use. PMID- 29581118 TI - Molecular Characterization of OXA-198 Carbapenemase-Producing Pseudomonas aeruginosa Clinical Isolates. AB - Carbapenemase-producing Pseudomonadaceae have increasingly been reported worldwide, with an ever-increasing heterogeneity of carbapenem resistance mechanisms, depending on the bacterial species and the geographical location. OXA 198 is a plasmid-encoded class D beta-lactamase involved in carbapenem resistance in one Pseudomonas aeruginosa isolate from Belgium. In the setting of a multicenter survey of carbapenem resistance in P. aeruginosa strains in Belgian hospitals in 2013, three additional OXA-198-producing P. aeruginosa isolates originating from patients hospitalized in one hospital were detected. To reveal the molecular mechanism underlying the reduced susceptibility to carbapenems, MIC determinations, whole-genome sequencing, and PCR analyses to confirm the genetic organization were performed. The plasmid harboring the blaOXA-198 gene was characterized, along with the genetic relatedness of the four P. aeruginosa isolates. The blaOXA-198 gene was harbored on a class 1 integron carried by an ~49-kb IncP-type plasmid proposed as IncP-11. The same plasmid was present in all four P. aeruginosa isolates. Multilocus sequence typing revealed that the isolates all belonged to sequence type 446, and single-nucleotide polymorphism analysis revealed only a few differences between the isolates. This report describes the structure of a 49-kb plasmid harboring the blaOXA-198 gene and presents the first description of OXA-198-producing P. aeruginosa isolates associated with a hospital-associated cluster episode. PMID- 29581119 TI - Genetic Relationships among Multidrug-Resistant Salmonella enterica Serovar Typhimurium Strains from Humans and Animals. AB - We identified 20 to 22 resistance genes, carried in four incompatibility groups of plasmids, in each of five genetically closely related Salmonella enterica serovar Typhimurium strains recovered from humans, pigs, and chickens. The genes conferred resistance to aminoglycosides, chloramphenicol, sulfonamides, trimethoprim, tetracycline, fluoroquinolones, extended-spectrum cephalosporins and cefoxitin, and azithromycin. This study demonstrates the transmission of multidrug-resistant Salmonella strains among humans and food animals and may be the first identification of mphA in azithromycin-resistant Salmonella strains in Taiwan. PMID- 29581120 TI - Influence of Reactive Oxygen Species on De Novo Acquisition of Resistance to Bactericidal Antibiotics. AB - The radical-based theory proposes that three major classes of bactericidal antibiotics, i.e., beta-lactams, quinolones, and aminoglycosides, have in common the downstream formation of lethal levels of reactive oxygen species (ROS) as part of the killing mechanism. If bactericidal antibiotics exhibit a common mechanism, then it is to be expected that the acquisition of resistance against these drugs would have some shared traits as well. Indeed, cells made resistant to one bactericidal antibiotic more rapidly became resistant to another. This effect was absent after induced resistance to a bacteriostatic drug. De novo acquisition of resistance to one bactericidal antibiotic provided partial protection to killing by bactericidal antibiotics from a different class. This protective effect was observed in short-term experiments. No protective effect was detected during 24-h exposures, suggesting that cross-resistance did not occur. In the wild-type strain, exposure to bactericidal antibiotics increased intracellular ROS levels. This increase in ROS levels was not observed when strains resistant to these drugs were exposed to the same concentrations. These results indicate that de novo acquisition of resistance to the bactericidal drugs tested involves a common cellular response that provides protection against ROS accumulation upon exposure to this type of antibiotics. A central mechanism or at least a few common elements within the separate mechanisms possibly play a role during the acquisition of antibiotic resistance. PMID- 29581121 TI - Dextromethorphan Attenuates NADPH Oxidase-Regulated Glycogen Synthase Kinase 3beta and NF-kappaB Activation and Reduces Nitric Oxide Production in Group A Streptococcal Infection. AB - Group A Streptococcus (GAS) is an important human pathogen that causes a wide spectrum of diseases, including necrotizing fasciitis and streptococcal toxic shock syndrome. Dextromethorphan (DM), an antitussive drug, has been demonstrated to efficiently reduce inflammatory responses, thereby contributing to an increased survival rate of GAS-infected mice. However, the anti-inflammatory mechanisms underlying DM treatment in GAS infection remain unclear. DM is known to exert neuroprotective effects through an NADPH oxidase-dependent regulated process. In the present study, membrane translocation of NADPH oxidase subunit p47phox and subsequent reactive oxygen species (ROS) generation induced by GAS infection were significantly inhibited via DM treatment in RAW264.7 murine macrophage cells. Further determination of proinflammatory mediators revealed that DM effectively suppressed inducible nitric oxide synthase (iNOS) expression and NO, tumor necrosis factor alpha, and interleukin-6 generation in GAS-infected RAW264.7 cells as well as in air-pouch-infiltrating cells from GAS/DM-treated mice. GAS infection caused AKT dephosphorylation, glycogen synthase kinase-3beta (GSK-3beta) activation, and subsequent NF-kappaB nuclear translocation, which were also markedly inhibited by treatment with DM and an NADPH oxidase inhibitor, diphenylene iodonium. These results suggest that DM attenuates GAS infection induced overactive inflammation by inhibiting NADPH oxidase-mediated ROS production that leads to downregulation of the GSK-3beta/NF-kappaB/NO signaling pathway. PMID- 29581122 TI - Pharmacokinetics of Intravenous Posaconazole in Critically Ill Patients. AB - To date, there is no information on the intravenous (i.v.) posaconazole pharmacokinetics for intensive care unit (ICU) patients. This prospective observational study aimed to describe the pharmacokinetics of a single dose of i.v. posaconazole in critically ill patients. Patients with no history of allergy to triazole antifungals and requiring systemic antifungal therapy were enrolled if they were aged >=18 years, central venous access was available, they were not pregnant, and they had not received prior posaconazole or drugs interacting with posaconazole. A single dose of 300 mg posaconazole was administered over 90 min. Total plasma concentrations were measured from serial plasma samples collected over 48 h, using a validated chromatographic method. The pharmacokinetic data set was analyzed by noncompartmental methods. Eight patients (7 male) were enrolled with the following characteristics: median age, 46 years (interquartile range [IQR], 40 to 51 years); median weight, 68 kg (IQR, 65 to 82 kg); and median albumin concentration, 20 g/liter (IQR, 18 to 24 g/liter). Median (IQR) pharmacokinetic parameter estimates were as follows: observed maximum concentration during sampling period (Cmax), 1,702 ng/ml (1,352 to 2,141 ng/ml); area under the concentration-time curve from zero to infinity (AUC0-infinity), 17,932 ng . h/ml (13,823 to 27,905 ng . h/ml); clearance (CL), 16.8 liters/h (11.1 to 21.7 liters/h); and volume of distribution (V), 529.1 liters (352.2 to 720.6 liters). The V and CL were greater than 2-fold and the AUC0-infinity was 39% of the values reported for heathy volunteers. The AUC0-infinity was only 52% of the steady-state AUC0-24 reported for hematology patients. The median of estimated average steady-state concentrations was 747 ng/ml (IQR, 576 to 1,163 ng/ml), which is within but close to the lower end of the previously recommended therapeutic range of 500 to 2,500 ng/ml. In conclusion, we observed different pharmacokinetics of i.v. posaconazole in this cohort of critically ill patients compared to those in healthy volunteers and hematology patients. PMID- 29581123 TI - CrpP Is a Novel Ciprofloxacin-Modifying Enzyme Encoded by the Pseudomonas aeruginosa pUM505 Plasmid. AB - The pUM505 plasmid, isolated from a clinical Pseudomonas aeruginosa isolate, confers resistance to ciprofloxacin (CIP) when transferred into the standard P. aeruginosa strain PAO1. CIP is an antibiotic of the quinolone family that is used to treat P. aeruginosa infections. In silico analysis, performed to identify CIP resistance genes, revealed that the 65-amino-acid product encoded by the orf131 gene in pUM505 displays 40% amino acid identity to the Mycobacterium smegmatis aminoglycoside phosphotransferase (an enzyme that phosphorylates and inactivates aminoglycoside antibiotics). We cloned orf131 (renamed crpP, for ciprofloxacin resistance protein, plasmid encoded) into the pUCP20 shuttle vector. The resulting recombinant plasmid, pUC-crpP, conferred resistance to CIP on Escherichia coli strain J53-3, suggesting that this gene encodes a protein involved in CIP resistance. Using coupled enzymatic analysis, we determined that the activity of CrpP on CIP is ATP dependent, while little activity against norfloxacin was detected, suggesting that CIP may undergo phosphorylation. Using a recombinant His-tagged CrpP protein and liquid chromatography-tandem mass spectrometry, we also showed that CIP was phosphorylated prior to its degradation. Thus, our findings demonstrate that CrpP, encoded on the pUM505 plasmid, represents a new mechanism of CIP resistance in P. aeruginosa, which involves phosphorylation of the antibiotic. PMID- 29581124 TI - Time to Endovascular Treatment and Outcome in Acute Ischemic Stroke: MR CLEAN Registry Results. AB - BACKGROUND: Randomized, clinical trials in selected acute ischemic stroke patients reported that for every hour delay of endovascular treatment (EVT), chances of functional independence diminish by up to 3.4%. These findings may not be fully generalizable to clinical practice because of strict in- and exclusion criteria in these trials. Therefore, we aim to assess the association of time to EVT with functional outcome in current, everyday clinical practice. METHODS: The MR CLEAN Registry (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in The Netherlands) is an ongoing, prospective, observational study in all centers that perform EVT in The Netherlands. Data were analyzed from patients treated between March 2014 and June 2016. In the primary analysis we assessed the association of time from stroke onset to start of EVT and time from stroke onset to successful reperfusion with functional outcome (measured with the modified Rankin Scale), by means of ordinal logistic regression. RESULTS: We analyzed 1488 patients with acute ischemic stroke who underwent EVT. An increased time to start of EVT was associated with worse functional outcome (adjusted common odds ratio, 0.83 per hour; 95% confidence interval, 0.77-0.89) and a 2.2% increase in mortality. Every hour increase from stroke onset to EVT start resulted in a 5.3% decreased probability of functional independence (modified Rankin Scale, 0-2). In the 742 patients with successful reperfusion, every hour increase from stroke onset to reperfusion was associated with a 7.7% decreased probability of functional independence. CONCLUSIONS: Time to EVT for acute ischemic stroke in current clinical practice is strongly associated with functional outcome. Our data suggest that this association might be even stronger than previously suggested in reports on more selected patient populations from randomized, controlled trials. These findings emphasize that functional outcome of EVT patients can be greatly improved by shortening onset to treatment times. PMID- 29581125 TI - Prevalence and Predictors of Cholesterol Screening, Awareness, and Statin Treatment Among US Adults With Familial Hypercholesterolemia or Other Forms of Severe Dyslipidemia (1999-2014). AB - BACKGROUND: Familial hypercholesterolemia (FH) and other extreme elevations in low-density lipoprotein cholesterol significantly increase the risk of atherosclerotic cardiovascular disease; however, recent data suggest that prescription rates for statins remain low in these patients. National rates of screening, awareness, and treatment with statins among individuals with FH or severe dyslipidemia are unknown. METHODS: Data from the 1999 to 2014 National Health and Nutrition Examination Survey were used to estimate prevalence rates of self-reported screening, awareness, and statin therapy among US adults (n=42 471 weighted to represent 212 million US adults) with FH (defined using the Dutch Lipid Clinic criteria) and with severe dyslipidemia (defined as low-density lipoprotein cholesterol levels >=190 mg/dL). Logistic regression was used to identify sociodemographic and clinical correlates of hypercholesterolemia awareness and statin therapy. RESULTS: The estimated US prevalence of definite/probable FH was 0.47% (standard error, 0.03%) and of severe dyslipidemia was 6.6% (standard error, 0.2%). The frequency of cholesterol screening and awareness was high (>80%) among adults with definite/probable FH or severe dyslipidemia; however, statin use was uniformly low (52.3% [standard error, 8.2%] of adults with definite/probable FH and 37.6% [standard error, 1.2%] of adults with severe dyslipidemia). Only 30.3% of patients with definite/probable FH on statins were taking a high-intensity statin. The prevalence of statin use in adults with severe dyslipidemia increased over time (from 29.4% to 47.7%) but not faster than trends in the general population (from 5.7% to 17.6%). Older age, health insurance status, having a usual source of care, diabetes mellitus, hypertension, and having a personal history of early atherosclerotic cardiovascular disease were associated with higher statin use. CONCLUSIONS: Despite the high prevalence of cholesterol screening and awareness, only ~50% of adults with FH are on statin therapy, with even fewer prescribed a high-intensity statin; young and uninsured patients are at the highest risk for lack of screening and for undertreatment. This study highlights an imperative to improve the frequency of cholesterol screening and statin prescription rates to better identify and treat this high-risk population. Additional studies are needed to better understand how to close these gaps in screening and treatment. PMID- 29581126 TI - SDF-1 Is an Autocrine Insulin-Desensitizing Factor in Adipocytes. AB - Insulin desensitization occurs not only under the obese diabetic condition but also in the fasting state. However, little is known about the common secretory factor(s) that are regulated under these two insulin-desensitized conditions. Here, using database analysis and in vitro and in vivo experiments, we identified stromal derived factor-1 (SDF-1) as an insulin-desensitizing factor in adipocytes, overexpressed in both fasting and obese adipose tissues. Exogenously added SDF-1 induced extracellular signal-regulated kinase signal, which phosphorylated and degraded IRS-1 protein in adipocytes, decreasing insulin mediated signaling and glucose uptake. In contrast, knockdown of endogenous SDF-1 or inhibition of its receptor in adipocytes markedly increased IRS-1 protein levels and enhanced insulin sensitivity, indicating the autocrine action of SDF 1. In agreement with these findings, adipocyte-specific ablation of SDF-1 enhanced insulin sensitivity in adipose tissues and in the whole body. These results point to a novel regulatory mechanism of insulin sensitivity mediated by adipose autocrine SDF-1 action and provide a new insight into the process of insulin desensitization in adipocytes. PMID- 29581127 TI - Acceptability of text messages for safety netting patients with low-risk cancer symptoms: a qualitative study. AB - BACKGROUND: Safety netting is an important diagnostic strategy for patients presenting to primary care with potential (low-risk) cancer symptoms. Typically, this involves asking patients to return if symptoms persist. However, this relies on patients re-appraising their symptoms and making follow-up appointments, which could contribute to delays in diagnosis. Text messaging is increasingly used in primary care to communicate with patients, and could be used to improve safety netting. AIM: To explore the acceptability and feasibility of using text messages to safety net patients presenting with low-risk cancer symptoms in GP primary care (txt-netting). DESIGN AND SETTING: Qualitative focus group and interview study with London-based GPs. METHOD: Participants were identified using convenience sampling methods. Five focus groups and two interviews were conducted with 22 GPs between August and December 2016. Sessions were audiorecorded, transcribed verbatim, and analysed using thematic analysis. RESULTS: GPs were amenable to the concept of using text messages in cancer safety netting, identifying it as an additional tool that could help manage patients and promote symptom awareness. There was wide variation in GP preferences for text message content, and a number of important potential barriers to txt-netting were identified. Concerns were raised about the difficulties of conveying complex safety netting advice within the constraints of a text message, and about confidentiality, widening inequalities, and workload implications. CONCLUSION: Text messages were perceived to be an acceptable potential strategy for safety netting patients with low-risk cancer symptoms. Further work is needed to ensure it is cost-effective, user friendly, confidential, and acceptable to patients. PMID- 29581128 TI - Improving palliative care provision in primary care: a pre- and post-survey evaluation among PaTz groups. AB - BACKGROUND: In PaTz (PAlliatieve Thuis Zorg, palliative care at home), modelled after the Gold Standards Framework, GPs and community nurses meet on a regular basis to identify patients with palliative care needs (the PaTz register), and to discuss care for these patients. AIM: To study the effects of the implementation of PaTz, and provide additional analyses on two important elements: the PaTz register and patient discussions. DESIGN AND SETTING: A pre- and post-evaluation among Dutch GPs (n = 195 before the start of PaTz; n = 166, 1 year after the start of PaTz). The GPs also provided data on recently deceased patients (n = 460 before the start of PaTz; n = 305 14 months after the start of PaTz). METHOD: GPs from all 37 PaTz groups filled in questionnaires. Pre- and post-test differences were analysed using multilevel analyses to adjust for PaTz group. RESULTS: Identification of patients with palliative care needs was done systematically for more patients after implementation of PaTz compared with before (54.3% versus 17.6%). After implementation, 64.8% of deceased patients had been included on the PaTz register. For these patients, when compared with patients not included on the PaTz register, preferred place of death was more likely to be known (88.1% of patients not on the register and 97.3% of deceased patients included on the register), GPs were more likely to have considered a possible death sooner (>1 month before death: 53.0% and 80.2%), and conversations on life expectancy, physical complaints, existential issues, and possibilities of care occurred more often (60.8% and 81.3%; 68.6% and 86.1%; 22.5% and 34.2%; 60.8% and 84.0%, respectively). CONCLUSIONS: Implementation of PaTz improved systematic identification of palliative care patients within the GP practice. Use of the PaTz register has added value. PMID- 29581129 TI - Computer screening for palliative care needs in primary care: a mixed-methods study. AB - BACKGROUND: Though the majority of people could benefit from palliative care before they die, most do not receive this approach, especially those with multimorbidity and frailty. GPs find it difficult to identify such patients. AIM: To refine and evaluate the utility of a computer application (AnticiPal) to help primary care teams screen their registered patients for people who could benefit from palliative care. DESIGN AND SETTING: A mixed-methods study of eight GP practices in Scotland, conducted in 2016-2017. METHOD: After a search development cycle the authors adopted a mixed-methods approach, combining analysis of the number of people identified by the search with qualitative observations of the computer search as used by primary care teams, and interviews with professionals and patients. RESULTS: The search identified 0.8% of 62 708 registered patients. A total of 27 multidisciplinary meetings were observed, and eight GPs and 10 patients were interviewed. GPs thought the search identified many unrecognised patients with advanced multimorbidity and frailty, but were concerned about workload implications of assessment and care planning. Patients and carers endorsed the value of proactive identification of people with advanced illness. CONCLUSION: GP practices can use computer searching to generate lists of patients for review and care planning. The challenges of starting a conversation about the future remain. However, most patients regard key components of palliative care (proactive planning, including sharing information with urgent care services) as important. Screening for people with deteriorating health at risk from unplanned care is a current focus for quality improvement and should not be limited by labelling it solely as 'palliative care'. PMID- 29581130 TI - Primary Care Outcomes Questionnaire: psychometric testing of a new instrument. AB - BACKGROUND: Patients attend primary care for many reasons and to achieve a range of possible outcomes. There is currently no Patient Reported Outcome Measure (PROM) designed to capture these diverse outcomes, and trials of interventions in primary care may thus fail to detect beneficial effects. AIM: This study describes the psychometric testing of the Primary Care Outcomes Questionnaire (PCOQ), which was designed to capture a broad range of outcomes relevant to primary care. DESIGN AND SETTING: Questionnaires were administered in primary care in South West England. METHOD: Patients completed the PCOQ in GP waiting rooms before a consultation, and a second questionnaire, including the PCOQ and seven comparator PROMs, after 1 week. Psychometric testing included exploratory factor analysis on the PCOQ, internal consistency, correlation coefficients between domain scores and comparator measures, and repeated measures effect sizes indicating change across 1 week. RESULTS: In total, 602 patients completed the PCOQ at baseline, and 264 (44%) returned the follow-up questionnaire. Exploratory factor analysis suggested four dimensions underlying the PCOQ items: health and wellbeing, health knowledge and self-care, confidence in health provision, and confidence in health plan. Each dimension was internally consistent and correlated as expected with comparator PROMs, providing evidence of construct validity. Patients reporting an improvement in their main problem exhibited small to moderate improvements in relevant domain scores on the PCOQ. CONCLUSION: The PCOQ was acceptable, feasible, showed strong psychometric properties, and was responsive to change. It is a promising new tool for assessment of outcomes of primary care interventions from a patient perspective.

PMID- 29581131 TI - Higher Absolute Lymphocyte Counts Predict Lower Mortality from Early-Stage Triple Negative Breast Cancer. AB - Purpose: Tumor-infiltrating lymphocytes (TIL) in pretreatment biopsies are associated with improved survival in triple-negative breast cancer (TNBC). We investigated whether higher peripheral lymphocyte counts are associated with lower breast cancer-specific mortality (BCM) and overall mortality (OM) in TNBC.Experimental Design: Data on treatments and diagnostic tests from electronic medical records of two health care systems were linked with demographic, clinical, pathologic, and mortality data from the California Cancer Registry. Multivariable regression models adjusted for age, race/ethnicity, socioeconomic status, cancer stage, grade, neoadjuvant/adjuvant chemotherapy use, radiotherapy use, and germline BRCA1/2 mutations were used to evaluate associations between absolute lymphocyte count (ALC), BCM, and OM. For a subgroup with TIL data available, we explored the relationship between TILs and peripheral lymphocyte counts.Results: A total of 1,463 stage I-III TNBC patients were diagnosed from 2000 to 2014; 1,113 (76%) received neoadjuvant/adjuvant chemotherapy within 1 year of diagnosis. Of 759 patients with available ALC data, 481 (63.4%) were ever lymphopenic (minimum ALC <1.0 K/MUL). On multivariable analysis, higher minimum ALC, but not absolute neutrophil count, predicted lower OM [HR = 0.23; 95% confidence interval (CI), 0.16-0.35] and BCM (HR = 0.19; CI, 0.11-0.34). Five year probability of BCM was 15% for patients who were ever lymphopenic versus 4% for those who were not. An exploratory analysis (n = 70) showed a significant association between TILs and higher peripheral lymphocyte counts during neoadjuvant chemotherapy.Conclusions: Higher peripheral lymphocyte counts predicted lower mortality from early-stage, potentially curable TNBC, suggesting that immune function may enhance the effectiveness of early TNBC treatment.

AB - Radiographic imaging continues to be one of the most effective and clinically useful tools within oncology. Sophistication of artificial intelligence has allowed for detailed quantification of radiographic characteristics of tissues using predefined engineered algorithms or deep learning methods. Precedents in radiology as well as a wealth of research studies hint at the clinical relevance of these characteristics. However, critical challenges are associated with the analysis of medical imaging data. Although some of these challenges are specific to the imaging field, many others like reproducibility and batch effects are generic and have already been addressed in other quantitative fields such as genomics. Here, we identify these pitfalls and provide recommendations for analysis strategies of medical imaging data, including data normalization, development of robust models, and rigorous statistical analyses. Adhering to these recommendations will not only improve analysis quality but also enhance precision medicine by allowing better integration of imaging data with other biomedical data sources.

PMID- 29581135 TI - ER+ Breast Cancers Resistant to Prolonged Neoadjuvant Letrozole Exhibit an E2F4 Transcriptional Program Sensitive to CDK4/6 Inhibitors. AB - Purpose: This study aimed to identify biomarkers of resistance to endocrine therapy in estrogen receptor-positive (ER+) breast cancers treated with prolonged neoadjuvant letrozole.Experimental Design: We performed targeted DNA and RNA sequencing in 68 ER+ breast cancers from patients treated with preoperative letrozole (median, 7 months).Results: Twenty-four tumors (35%) exhibited a PEPI score >=4 and/or recurred after a median of 58 months and were considered endocrine resistant. Integration of the 47 most upregulated genes (log FC > 1, FDR < 0.03) in letrozole-resistant tumors with transcription-binding data showed significant overlap with 20 E2F4-regulated genes (P = 2.56E-15). In patients treated with the CDK4/6 inhibitor palbociclib before surgery, treatment significantly decreased expression of 24 of the 47 most upregulated genes in letrozole-resistant tumors, including 18 of the 20 E2F4 target genes. In long term estrogen-deprived ER+ breast cancer cells, palbociclib also downregulated all 20 E2F4 target genes and P-RB levels, whereas the ER downregulator fulvestrant or paclitaxel only partially suppressed expression of this set of genes and had no effect on P-RB. Finally, an E2F4 activation signature was strongly associated with resistance to aromatase inhibitors in the ACOSOG Z1031B neoadjuvant trial and with an increased risk of relapse in adjuvant-treated ER+ tumors in METABRIC.Conclusions: In tumors resistant to prolonged neoadjuvant letrozole, we identified a gene expression signature of E2F4 target activation. CDK4/6 inhibition suppressed E2F4 target gene expression in estrogen-deprived ER+ breast cancer cells and in patients' ER+ tumors, suggesting a potential benefit of adjuvant CDK4/6 inhibitors in patients with ER+ breast cancer who fail to respond to preoperative estrogen deprivation.

PMID- 29581138 TI - Acupuncture in the emergency department: a systematic review of randomised controlled trials. AB - INTRODUCTION: A comprehensive review of both English and Chinese language literature to inform acupuncture practice in emergency department (ED) settings is lacking. Accordingly, we aimed to conduct a systematic review of English and Chinese randomised controlled trials (RCTs) of acupuncture use in the ED. METHODS: Four English databases (Embase, PubMed, AMED and CENTRAL) and two Chinese databases (CNKI and Wanfang) were systematically searched using the keywords 'acupuncture' and 'emergency department', followed by a bibliographic search of references. The data were extracted and assessed by two independent authors. RCTs were selected based on pre-defined criteria. Data were extracted and a risk of bias assessment was performed using the Cochrane risk of bias tool. The quality of evidence was rated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: In total, 1461 articles were screened and six RCTs involving 651 patients were included. For various acute pain conditions, acupuncture was superior to sham acupuncture, more effective than intravenous morphine, comparable to conventional ED treatment, and superior to standard ED care alone when used on an adjuvant basis; however, the overall level of evidence was low. Studies that applied acupuncture in hypertension and cardiac arrest were deemed to be at high risk of bias, and the level of evidence for these outcomes was very low. No major adverse events were reported in the included studies. CONCLUSION: There is a lack of high-quality evidence to support the use of acupuncture in the ED. Multicentre RCTs with rigorous designs are warranted. PMID- 29581139 TI - Regulation of the IL-33/ST2 pathway contributes to the anti-inflammatory effect of acupuncture in the ovalbumin-induced murine asthma model. AB - BACKGROUND: Bronchial asthma is a chronic airway inflammatory disease which has three main pathological features: airway hyperresponsiveness (AHR), airway remodelling, and chronic inflammation. Acupuncture is known to be an effective integrative medical therapy that has been used in the treatment of several chronic diseases, including bronchial asthma. The aim of the current study was to evaluate the effects of acupuncture on inflammation and regulation of the IL 33/ST2 pathway in a mouse model of asthma. METHODS: The murine asthma model was established by both injection and inhalation of ovalbumin (OVA). Within 24 hours of the last OVA challenge, lung function was assessed by measurement of the airway resistance (RL) and lung dynamic compliance (Cdyn). Pulmonary tissues were collected for the detection of pathological changes and mucus secretion. Serum levels of tumour necrosis factor alpha (TNF-alpha), interleukin (IL)-1beta, IL-33 and sST2 (secreted ST2) were detected by ELISA. Th17 cell proportions and counts in bronchoalveolar lavage fluid (BALF) were analysed by flow cytometry. RESULTS: The results showed that AHR, chronic inflammation and mucus secretion were significantly suppressed by acupuncture treatment. RL decreased while Cdyn increased after acupuncture treatment. There was an apparent decrease in the serum concentrations of certain pro-inflammatory cytokines, such as TNF-alpha, IL 1beta and IL-33, and an increase in sST2 level compared with untreated asthmatic mice. Acupuncture also reduced the CD4 +IL-17A+ cell proportion and counts in BALF. CONCLUSION: Acupuncture effectively protects lung function and attenuates airway inflammation in the OVA-induced mouse model of asthma, which supports the role of acupuncture as a potential therapy in asthma treatment. PMID- 29581140 TI - Transmission of a TP53 germline mutation from unaffected male carrier associated with pediatric glioblastoma in his child and gestational choriocarcinoma in his female partner. AB - Li-Fraumeni syndrome (LFS) is an autosomal dominant cancer predisposition syndrome caused by germline alterations in the tumor suppressor gene TP53 LFS is associated with numerous malignancies including astrocytoma. Sanger sequencing and chromosomal microarray studies of blood and tumor tissue from a 4-yr-old boy with glioblastoma demonstrated a germline TP53 mutation with loss of heterozygosity for the short arm of Chromosome 17 as the second inactivating event in the tumor. There was no family history of LFS, but the child's mother had recently died from metastatic choriocarcinoma after antecedent normal term delivery of a then 6-mo-old daughter. The choriocarcinoma contained the same TP53 mutation detected in the proband and the 6-mo-old daughter was confirmed to be a carrier. Unexpectedly, the germline TP53 mutation was found to be inherited from the unaffected father. We report here the second genetically confirmed case of TP53-mutated choriocarcinoma in the partner of an LFS patient. Based on this case and recent literature, female partners of LFS patients may have increased risk of choriocarcinoma due to transmission of germline TP53 mutation from male carriers. Although the Toronto protocol has established an effective approach to detect tumors and improve survival in children and adults with LFS, there is a need to expand the current criteria to include surveillance of female partners of LFS patients for choriocarcinoma and other gestational trophoblastic disease. Recognition of this unique mode of transmission of TP53 mutations should be considered in genetic counseling for cancer risk assessment and family planning. PMID- 29581141 TI - Risk factors for, and prevention of, shoulder injuries in overhead sports: a systematic review with best-evidence synthesis. AB - OBJECTIVE: To assess the evidence for risk factors and prevention measures for shoulder injuries in overhead sports. DESIGN: Systematic review with best evidence synthesis. DATA SOURCES: Medline (Ovid), PubMed (complementary search), Embase (Elsevier), Cochrane (Wiley), SPORTDiscus (Ebsco) and Web of Science Core Collection (Thomson Reuters), from 1 January 1990 to 15 May 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials, cohort studies and case-control studies on risk factors or prevention measures for shoulder injuries in overhead sports. The eligible studies were quality assessed using the Scottish Intercollegiate Guidelines Network criteria. RESULTS: Of 4778 studies identified, 38 were eligible for quality review and 17 met the quality criteria to be included in the evidence synthesis. One additional quality study presented a shoulder injury prevention programme. Most studies focused on baseball, lacrosse or volleyball (n=13). The risk factors examined included participation level (competition vs training) (n=10), sex (n=4), biomechanics (n=2) and external workload (n=2). The evidence for all risk factors was limited or conflicting. The effect of the prevention programme within the subgroup of uninjured players at baseline was modest and possibly lacked statistical power. CONCLUSIONS: All investigated potential risk factors for shoulder injury in overhead sports had limited evidence, and most were non-modifiable (eg, sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports. PROSPERO TRIAL REGISTRATION NUMBER: CRD42015026850.

PMID- 29581142 TI - Femoroacetabular impingement surgery allows 74% of athletes to return to the same competitive level of sports participation but their level of performance remains unreported: a systematic review with meta-analysis. AB - BACKGROUND: Femoroacetabular impingement (FAI) syndrome is one source of hip pain that can limit sport participation among athletes. OBJECTIVE: To summarise the return to sport (RTS) rate for athletes after surgery for FAI syndrome. METHODS: A computer-assisted search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and EMBASE databases was performed using keywords related to RTS and RTS at preinjury level (RTSPRE) of competition for FAI syndrome. The risk of bias in the included studies was assessed using the Methodological Index for Non-Randomized Studies scale. RESULTS: 35 studies (1634 athletes/1828 hips) qualified for analysis. Based on evidence of limited to moderate strength (level 3b to 4 studies), athletes return to sport at preinjury level post surgery for FAI syndrome at a rate of only 74% (67%-81%). Only 37% of studies reported RTSPRE. The mean time from surgery to RTS was 7.0+/-2.6 months. The mean follow-up postsurgery was 28.1+/-15.5 months. Professional athletes returned to sport (p=0.0002) (although not the preinjury sport level; p=0.63) at a higher rate than collegiate athletes. Only 14% of studies reported on athletic presurgery and postsurgery athletic performance, which means it is impossible to comment on whether athletes return to their previous level of performance or not. No studies reported on the specific criteria used to permit players to return to sport. 20% of studies reported on career longevity, 51% reported surgical complications and 77% reported on surgical failures. CONCLUSION: There was limited to moderate evidence that one in four athletes did not return to their previous level of sport participation after surgery for FAI syndrome. Only 37% of the included studies clearly distinguished RTS from RTSPRE. Poor outcome reporting on athletic performance postsurgery makes it difficult to determine to what level of performance these athletes actually perform. Thus, if a player asks a surgeon 'Will I get back to my previous level of performance?' there are presently little to no published data from which to base an answer.

PMID- 29581146 TI - Inhibition of miR-34a-5p alleviates hypoxia-reoxygenation injury by enhancing autophagy in steatotic hepatocytes. AB - Hypoxia-reoxygenation (H/R) injury in steatotic hepatocytes has been implicated in liver dysfunction after liver transplantation. MicroRNAs (miRs) play important roles in regulating several cell biology mechanisms related to H/R injury. However, the role of miRs in regulating H/R injury in steatotic hepatocytes is still unclear. We established an in vitro model for studying H/R injury in steatotic hepatocytes and identified miR-34a-5p as a miR that was substantially upregulated in steatotic hepatocytes under H/R challenge. MiR-34a-5p expression was modified by transfecting miR-34a-5p mimic and inhibitor into H/R-challenged steatotic hepatocytes. We found that inhibition of miR-34a-5p alleviated H/R induced apoptosis and promoted post-H/R proliferation in steatotic hepatocytes. Whereas, overexpression of miR-34a-5p augmented H/R-induced apoptosis and prohibited post-H/R proliferation. By examining autophagy, our data demonstrated that miR-34a-5p suppressed autophagy in H/R-challenged steatotic hepatocytes, induction of autophagy partially rescued the exaggeration of H/R injury induced by miR-34a-5p mimic, while inhibition of autophagy impaired the protection of the miR-34a-5p inhibitor against H/R injury. In conclusion, miR-34a-5p is crucial in exaggerating H/R injury, likely by suppressing autophagy in steatotic hepatocytes. Inhibition of miR-34a may be a promising strategy to protect steatotic hepatocytes against H/R-injury. PMID- 29581147 TI - Gtgen3A, a novel plant GH3 beta-glucosidase, modulates gentio-oligosaccharide metabolism in Gentiana. AB - Gentiobiose, a beta-1,6-linked glycosyl-disaccharide, accumulates abundantly in Gentianaceae and is involved in aspects of plant development, such as fruits ripening and release of bud dormancy. However, the mechanisms regulating the amount of gentio-oligosaccharide accumulation in plants remain obscure. The present study aimed to identify an enzyme that modulates gentio-oligosaccharide amount in gentian (Gentiana triflora). A protein responsible for gentiobiose hydrolysis, GtGen3A, was identified by partial purification and its peptide sequence analysis. The enzyme had a molecular mass of ~67 kDa without a secretory signal peptide sequence. Sequence analysis revealed that GtGen3A could be a beta glucosidase member belonging to glycoside hydrolase family 3 (GH3). GtGen3A showed a homology to GH3 beta-glucan exohydrolases, ExoI of Hordeum vulgare, and ExgI from Zea mays, which preferentially hydrolyzed beta-1,3- and beta-1,4-linked oligosaccharides. The purified recombinant GtGen3A (rGtGen3A) produced in Escherichia coli showed optimal reaction at pH 6.5 and 20 degrees C. The rGtGen3A liberated glucose from beta-1,2-, beta-1,3-, beta-1,4-, and beta-1,6-linked oligosaccharides, and showed the highest activity toward gentiotriose among the substrates tested. Kinetic analysis also revealed that rGtGen3A preferentially hydrolyzed gentiotriose. Virus-induced gene silencing of Gtgen3A in gentian plantlets resulted in predominant accumulation of gentiotriose rather than gentiobiose. Furthermore, the expression level of Gtgen3A was almost similar to the amount of gentiobiose in field-grown gentians. These findings suggest that the main function of GtGen3A is the hydrolysis of gentiotriose to gentiobiose, and that GtGen3A plays a role in modulating gentiobiose amounts in gentian. PMID- 29581150 TI - Environmental cadmium exposure is associated with elevated risk of chronic otitis media in adults. AB - OBJECTIVES: Chronic otitis media (COM) is caused by an infection of the middle ear, although it may also be associated with environmental pollutants. Recent reports found that cadmium exposure could be toxic to middle ear cell lines, but the role of cadmium in the development of COM in humans has not been examined to date. We hypothesised that environmental cadmium exposure was associated with an increased risk of COM in the general population. METHODS: We analysed cross sectional data for 5331 adults of 20 years of age or above, obtained from the Korea National Health and Nutrition Examination Survey 2010-2012. We examined the association between blood cadmium levels and COM diagnosed by an otolaryngologist. RESULTS: The highest quartile group of cadmium blood concentration was associated with an OR of 3.33 (95% CI 1.78 to 7.53) for COM, after adjusting for potential confounding factors. Doubling blood cadmium concentration resulted in an OR of 1.58 (95% CI 1.19 to 2.08) for COM. These associations were robust on sensitivity analyses after excluding current smokers and former smokers and after excluding subjects with a potential history of occupational exposure to cadmium. CONCLUSIONS: The results of our study suggest that environmental cadmium exposure is associated with increased risk of COM, and further studies are warranted to understand the pathogenetic mechanism by which COM is caused by cadmium exposure. PMID- 29581148 TI - Transcriptional regulatory networks underlying gene expression changes in Huntington's disease. AB - Transcriptional changes occur presymptomatically and throughout Huntington's disease (HD), motivating the study of transcriptional regulatory networks (TRNs) in HD We reconstructed a genome-scale model for the target genes of 718 transcription factors (TFs) in the mouse striatum by integrating a model of genomic binding sites with transcriptome profiling of striatal tissue from HD mouse models. We identified 48 differentially expressed TF-target gene modules associated with age- and CAG repeat length-dependent gene expression changes in Htt CAG knock-in mouse striatum and replicated many of these associations in independent transcriptomic and proteomic datasets. Thirteen of 48 of these predicted TF-target gene modules were also differentially expressed in striatal tissue from human disease. We experimentally validated a specific model prediction that SMAD3 regulates HD-related gene expression changes using chromatin immunoprecipitation and deep sequencing (ChIP-seq) of mouse striatum. We found CAG repeat length-dependent changes in the genomic occupancy of SMAD3 and confirmed our model's prediction that many SMAD3 target genes are downregulated early in HD. PMID- 29581149 TI - High-resolution definition of humoral immune response correlates of effective immunity against HIV. AB - Defining correlates of immunity by comprehensively interrogating the extensive biological diversity in naturally or experimentally protected subjects may provide insights critical for guiding the development of effective vaccines and antibody-based therapies. We report advances in a humoral immunoprofiling approach and its application to elucidate hallmarks of effective HIV-1 viral control. Systematic serological analysis for a cohort of HIV-infected subjects with varying viral control was conducted using both a high-resolution, high throughput biophysical antibody profiling approach, providing unbiased dissection of the humoral response, along with functional antibody assays, characterizing antibody-directed effector functions such as complement fixation and phagocytosis that are central to protective immunity. Profiles of subjects with varying viral control were computationally analyzed and modeled in order to deconvolute relationships among IgG Fab properties, Fc characteristics, and effector functions and to identify humoral correlates of potent antiviral antibody directed effector activity and effective viral suppression. The resulting models reveal multifaceted and coordinated contributions of polyclonal antibodies to diverse antiviral responses, and suggest key biophysical features predictive of viral control.

PMID- 29581153 TI - AICAR Prevents Acute Olanzapine-Induced Disturbances in Glucose Homeostasis. AB - Olanzapine (OLZ) is an antipsychotic drug used in the treatment of schizophrenia. Although effective in reducing psychoses, OLZ causes acute increases in blood glucose. The acute effects of OLZ on hyperglycemia are likely caused by reductions in insulin secretion, insulin resistance, and increased hepatic glucose production. 5AMP-activated protein kinase (AMPK) is an energy sensor activated during exercise that can increase insulin sensitivity and insulin independent glucose uptake in muscle. 5-Aminoimidazole-4-carboxamide ribonucleoside (AICAR) is a pharmacologic agent that, among other effects, can activate AMPK in vivo. Conversely, hypothalamic activation of AMPK has been suggested to mediate the hyperglycemic effects of OLZ. The purpose of this investigation was to determine whether cotreatment with AICAR could prevent acute OLZ-induced hyperglycemia in lean and obese C57BL6/J mice. OLZ (5 mg/kg, i.p.) caused rapid increases in blood glucose, a blunted insulin response, and pyruvate intolerance, all of which were prevented with AICAR cotreatment in both lean and obese mice. AICAR did not affect OLZ-induced changes in whole-body substrate oxidation or energy expenditure. Peripheral injection of AICAR, but not OLZ, activated AMPK signaling in the hypothalamus. The results of the current study provide evidence that AICAR prevents OLZ-induced hyperglycemia, despite increasing hypothalamic AMPK signaling. These protective effects were associated with the preservation of whole-body insulin action and reductions in markers of liver glucose production. PMID- 29581154 TI - Sepiapterin Enhances Tumor Radio- and Chemosensitivities by Promoting Vascular Normalization. AB - Previously, we demonstrated that nitric oxide (NO) synthase (NOS) is uncoupled in a wide range of solid tumors and that restoring NOS coupling with the tetrahydrobiopterin precursor sepiapterin (SP) inhibits tumor progression. Endothelial dysfunction characterizes the poorly functional vasculature of solid tumors, and since NO is critical for regulation of endothelial function we asked whether SP, by recoupling NOS, improves tumor vasculature structure and function enhancing chemotherapeutic delivery and response to radiotherapy. MMTV-neu mice with spontaneous breast tumors were treated with SP by oral gavage and evaluated by multispectral optoacoustic tomographic analysis of tumor HbO2 and by tissue staining for markers of hypoxia, blood perfusion, and markers of endothelial and smooth muscle proteins. Recoupling tumor NOS activity results in vascular normalization observed as reduced tumor hypoxia, improved tumor percentage of HbO2 and perfusion, as well as increased pericyte coverage of tumor blood vessels. The normalized vasculature and improved tumor oxygenation led to a greater than 2-fold increase in radiation-induced apoptosis compared with radiation or SP alone. High-performance liquid chromatography analysis of tumor doxorubicin levels showed a greater than 50% increase in doxorubicin uptake and a synergistic effect on tumor cell apoptosis. This study highlights for the first time the importance of NOS uncoupling and endothelial dysfunction in the development of tumor vasculature and presents a new approach for improving the tumoricidal efficacies of chemotherapy and radiotherapy. PMID- 29581155 TI - Disorders of sex development: timing of diagnosis and management in a single large tertiary center. AB - BACKGROUND: We describe the phenotypic spectrum and timing of diagnosis and management in a large series of patients with disorders of sexual development (DSD) treated in a single pediatric tertiary center. METHODS: DSD patients who had visited our tertiary center during the survey period (between 2004 and 2014) were identified based on an ICD-10 inquiry, and their phenotypic and molecular genetic findings were recorded from patient charts. RESULTS: Among the 550 DSD patients, 53.3% had 46,XY DSD; 37.1% had sex chromosome DSD and 9.6% had 46,XX DSD. The most common diagnoses were Turner syndrome (19.8%, diagnosed at the mean age of 4.7 +/- 5.5 years), Klinefelter syndrome (14.5%, 6.8 +/- 6.2 years) and bilateral cryptorchidism (23.1%). Very few patients with 46,XY DSD (7%) or 46,XX DSD (21%) had molecular genetic diagnosis. The yearly rate of DSD diagnoses remained stable over the survey period. After the release of the Nordic consensus on the management of undescended testes, the age at surgery for bilateral cryptorchidism declined significantly (P < 0.001). CONCLUSIONS: Our results show that (i) Turner syndrome and Klinefelter syndrome, the most frequent single DSD diagnoses, are still diagnosed relatively late; (ii) a temporal shift was observed in the management of bilateral cryptorchidism, which may favorably influence patients' adulthood semen quality and (iii) next-generation sequencing methods are not fully employed in the diagnostics of DSD patients. PMID- 29581156 TI - Height outcome of the recombinant human growth hormone treatment in Turner syndrome: a meta-analysis. AB - OBJECTIVE: This study sought to determine the effect of the recombinant human growth hormone (rhGH) treatment of Turner syndrome (TS) on height outcome. METHODS: We searched in MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews. A literature search identified 640 records. After screening and full-text assessment, 11 records were included in the systematic review. Methodological quality was assessed using the Cochrane Risk of Bias tool. RevMan 5.3 software was used for meta-analysis. We also assessed the quality of evidence with the GRADE system. RESULTS: Compared with controls, rhGH therapy led to increased final height (MD = 7.22 cm, 95% CI 5.27-9.18, P < 0.001, I2 = 4%; P = 0.18), height standard deviation (HtSDS) (SMD = 1.22, 95% CI 0.88-1.56, P < 0.001, I2 = 49%; P = 0.14) and height velocity (HV) (MD 2.68 cm/year; 95% CI 2.34, 3.02; P < 0.001, I2 = 0%; P = 0.72). There was a small increase in bone age (SMD 0.32 years; 95% CI 0.1, 0.54; P = 0.004, I2 = 73%; P = 0.02) after rhGH therapy for 12 months. What is more, the rhGH/oxandrolone combination therapy suggested greater final height (MD 2.46 cm; 95% CI 0.73, 4.18; P = 0.005, I2 = 32%; P = 0.22), increase and faster HV (SMD 1.67 cm/year; 95% CI 1.03, 2.31; P < 0.03, I2 = 80%; P < 0.001), with no significant increase in HtSDS and bone maturation compared with rhGH therapy alone. CONCLUSIONS: For TS patients, rhGH alone or with concomitant use of oxandrolone treatment had advantages on final height. PMID- 29581157 TI - Regulation of mitochondrial trifunctional protein modulates nonalcoholic fatty liver disease in mice. AB - Mitochondrial trifunctional protein (MTP) plays a critical role in the oxidation of long-chain fatty acids. We previously reported that aging mice (>9 months old) heterozygous for an MTP defect (MTP+/-) develop nonalcoholic fatty liver disease (NAFLD). We tested whether a high-fat diet (HFD) accelerates NAFLD in young MTP+/ mice, and whether overexpression of the nicotinamide adenine dinucleotide (NAD+) dependent deacetylase sirtuin 3 (SIRT3) deacetylates MTP and improves mitochondrial function and NAFLD. Three-month-old WT and MTP+/- mice were fed HFD (60% cal fat) for 16 weeks and livers were assessed for fatty acid oxidation (FAO) and NAFLD. Compared with WT, MTP+/- mice displayed reduced hepatic SIRT3 levels and reduced FAO, with increased hepatic steatosis and the inflammatory marker CD68. Hepatic overexpression of SIRT3 in HFD-fed MTP+/- mice increased hepatic MTP protein levels at the posttranscriptional level. Immunoprecipitation of MTP from liver mitochondria followed by Western blot with acetyl-lysine antibody showed higher acetylation of MTP in MTP+/- compared with WT mice. Overexpression of SIRT3 in MTP+/- mice significantly reduced the acetylation of MTP compared with beta-galactosidase controls, increased mitochondrial FAO, and reduced hepatic steatosis, CD68, and serum ALT levels. Taken together, our data indicate that deacetylation of MTP by SIRT3 improves mitochondrial function and rescues NAFLD in MTP+/- mice.

PMID- 29581158 TI - Chymase released from hypoxia-activated cardiac mast cells cleaves human apoA-I at Tyr192 and compromises its cardioprotective activity. AB - ApoA-I, the main structural and functional protein of HDL particles, is cardioprotective, but also highly sensitive to proteolytic cleavage. Here, we investigated the effect of cardiac mast cell activation and ensuing chymase secretion on apoA-I degradation using isolated rat hearts in the Langendorff perfusion system. Cardiac mast cells were activated by injection of compound 48/80 into the coronary circulation or by low-flow myocardial ischemia, after which lipid-free apoA-I was injected and collected in the coronary effluent for cleavage analysis. Mast cell activation by 48/80 resulted in apoA-I cleavage at sites Tyr192 and Phe229, but hypoxic activation at Tyr192 only. In vitro, the proteolytic end-product of apoA-I with either rat or human chymase was the Tyr192 truncated fragment. This fragment, when compared with intact apoA-I, showed reduced ability to promote migration of cultured human coronary artery endothelial cells in a wound-healing assay. We propose that C-terminal truncation of apoA-I by chymase released from cardiac mast cells during ischemia impairs the ability of apoA-I to heal damaged endothelium in the ischemic myocardium.

PMID- 29581161 TI - Smoking abstinence 1 year after acute coronary syndrome: follow-up from a randomized controlled trial of varenicline in patients admitted to hospital. AB - BACKGROUND: Patients who continue to smoke after acute coronary syndrome are at increased risk of reinfarction and death. We previously found use of varenicline to increase abstinence 24 weeks after acute coronary syndrome; here we report results through 52 weeks. METHODS: The EVITA trial was a multicentre, double blind, randomized, placebo-controlled trial of varenicline for smoking cessation in patients admitted to hospital with acute coronary syndrome. Participants were randomly assigned (1:1) to receive varenicline or placebo for 12 weeks, in conjunction with low-intensity counselling. Smoking abstinence was assessed via 7 day recall, with biochemical validation using exhaled carbon monoxide. Participants lost to follow-up or withdrawn were assumed to have returned to smoking. RESULTS: Among the 302 participants, abstinence declined over the course of the trial, with 34.4% abstinent 52 weeks after acute coronary syndrome. Compared with placebo, point estimates suggest use of varenicline increased point prevalence abstinence (39.9% v. 29.1%, difference 10.7%, 95% confidence interval [CI] 0.01% to 21.44%; number needed to treat 10), continuous abstinence (31.1% v. 21.2%, difference 9.9%, 95% CI -0.01% to 19.8%) and reduction in daily cigarette smoking by 50% or greater (57.8% v. 49.7%, difference 8.1%, 95% CI -3.1% to 19.4%). Varenicline and placebo groups had similar occurrence of serious adverse events (24.5% v. 21.9%, risk difference 2.7%, 95% CI -7.3% to 12.6%) and major adverse cardiovascular events (8.6% v. 9.3%, risk difference -0.7%, 95% CI -7.8% to 6.5%). INTERPRETATION: Varenicline was efficacious for smoking cessation in this high-risk patient population. However, 60% of patients who received treatment with varenicline still returned to smoking.

AB - BACKGROUND: Australia introduced tamper-resistant controlled-release (CR) oxycodone in April 2014. We quantified the impact of the reformulation on dispensing, switching and poisonings. METHODS: We performed interrupted time series analyses using population-representative national dispensing data from 2012 to 2016. We measured dispensing of oxycodone CR (>= 10 mg), discontinuation of use of strong opioids and switching to other strong opioids after the reformulation compared with a historical control period. Similarly, we compared calls about intentional opioid poisoning using data from a regional poisons information centre. RESULTS: After the reformulation, dispensing decreased for 10 30 mg (total level shift -11.1%, 95% confidence interval [CI], -17.2% to -4.6%) and 40-80 mg oxycodone CR (total level shift -31.5%, 95% CI -37.5% to -24.9%) in participants less than 65 years of age but was unchanged in people 65 years of age or older. Compared with the previous year, discontinuation of use of strong opioids did not increase (adjusted hazard ratio [HR] 0.95, 95% CI 0.91 to 1.00), but switching to oxycodone/naloxone did increase (adjusted HR 1.54, 95% CI 1.32 to 1.79). Switching to morphine varied by age (p < 0.001), and the greatest increase was in participants less than 45 years of age (adjusted HR 4.33, 95% CI 2.13 to 8.80). Participants switching after the reformulation were more likely to be dispensed a tablet strength of 40 mg or more (adjusted odds ratio [OR] 1.40, 95% CI 1.09 to 1.79). Calls for intentional poisoning that involved oxycodone taken orally increased immediately after the reformulation (incidence rate ratio (IRR) 1.31, 95% CI 1.05-1.64), but there was no change for injected oxycodone. INTERPRETATION: The reformulation had a greater impact on opioid access patterns of people less than 65 years of age who were using higher strengths of oxycodone CR. This group has been identified as having an increased risk of problematic opioid use and warrants closer monitoring in clinical practice.

PMID- 29581176 TI - Identification of Pik3ca Mutation as a Genetic Driver of Prostate Cancer That Cooperates with Pten Loss to Accelerate Progression and Castration-Resistant Growth. AB - Genetic alterations that potentiate PI3K signaling are frequent in prostate cancer, yet how different genetic drivers of the PI3K cascade contribute to prostate cancer is unclear. Here, we report PIK3CA mutation/amplification correlates with poor survival of patients with prostate cancer. To interrogate the requirement of different PI3K genetic drivers in prostate cancer, we employed a genetic approach to mutate Pik3ca in mouse prostate epithelium. We show Pik3caH1047R mutation causes p110alpha-dependent invasive prostate carcinoma in vivo Furthermore, we report that PIK3CA mutation and PTEN loss coexist in patients with prostate cancer and can cooperate in vivo to accelerate disease progression via AKT-mTORC1/2 hyperactivation. Contrasting single mutants that slowly acquire castration-resistant prostate cancer (CRPC), concomitant Pik3ca mutation and Pten loss caused de novo CRPC. Thus, Pik3ca mutation and Pten deletion are not functionally redundant. Our findings indicate that PIK3CA mutation is an attractive prognostic indicator for prostate cancer that may cooperate with PTEN loss to facilitate CRPC in patients.Significance: We show PIK3CA mutation correlates with poor prostate cancer prognosis and causes prostate cancer in mice. Moreover, PIK3CA mutation and PTEN loss coexist in prostate cancer and can cooperate in vivo to accelerate tumorigenesis and facilitate CRPC. Delineating this synergistic relationship may present new therapeutic/prognostic approaches to overcome castration/PI3K-AKT-mTORC1/2 inhibitor resistance. Cancer Discov; 8(6); 764-79.

PMID- 29581173 TI - Structural mechanisms of CFTR function and dysfunction. AB - Cystic fibrosis (CF) transmembrane conductance regulator (CFTR) chloride channel plays a critical role in regulating transepithelial movement of water and electrolyte in exocrine tissues. Malfunction of the channel because of mutations of the cftr gene results in CF, the most prevalent lethal genetic disease among Caucasians. Recently, the publication of atomic structures of CFTR in two distinct conformations provides, for the first time, a clear overview of the protein. However, given the highly dynamic nature of the interactions among CFTR's various domains, better understanding of the functional significance of these structures requires an integration of these new structural insights with previously established biochemical/biophysical studies, which is the goal of this review. PMID- 29581177 TI - RECX Interacts with Mitochondrial RECA to Maintain Mitochondrial Genome Stability. AB - The chloroplast and mitochondrial genomes are essential for photosynthesis and respiration, respectively. RECA and RECG, which are plant-specific homologs of the bacterial homologous recombination repair proteins RecA and RecG, maintain organelle genome stability by suppressing aberrant recombination between short dispersed repeats (SDRs) in the moss Physcomitrella patens In this study, we analyzed the plant-specific factor RECX, a homolog of bacterial RecX that regulates RecA. RECX fused to GFP colocalized with mitochondrial RECA1 and chloroplast RECA2 on mitochondrial and chloroplast nucleoids, respectively. Knockout (KO) and overexpression (OEX) of RECX did not alter the P. patens morphological phenotype. Analysis of mitochondrial DNA, however, showed that products from recombination between SDRs increased significantly in RECX OEX mitochondria and modestly in RECX KO mitochondria. By contrast, analysis of chloroplast DNA revealed no substantial alteration in the number of products from recombination between SDRs in RECX KO and OEX chloroplasts. Yeast two-hybrid analysis revealed interactions between RECX and RECA1 and between RECX and RECA2. Expression profiles showed a positive correlation between RECX and factors maintaining the stability of both organelle genomes and RECA1 Collectively, these results suggest that RECX maintains mitochondrial genome stability, likely by modulating RECA1 activity, and that the compromised function of RECX induces mitochondrial genome instability. PMID- 29581178 TI - Rice Morphology Determinant-Mediated Actin Filament Organization Contributes to Pollen Tube Growth. AB - For successful fertilization in angiosperms, rapid tip growth in pollen tubes delivers the male gamete into the ovules. The actin-binding protein-mediated organization of the actin cytoskeleton within the pollen tube plays a crucial role in this polarized process. However, the mechanism underlying the polarity of the actin filament (F-actin) array and behaviors in pollen tube growth remain largely unknown. Here, we demonstrate that an actin-organizing protein, Rice Morphology Determinant (RMD), a type II formin from rice (Oryza sativa), controls pollen tube growth by modulating the polarity and distribution of the F-actin array. The rice rmd mutant exhibits abnormal pollen tube growth and a decreased germination rate of the pollen grain in vitro and in vivo. The rmd pollen tubes display a disorganized F-actin pattern with disrupted apical actin density and shank longitudinal cable direction/arrangement, indicating the novel role of RMD in F-actin polarity during tip growth. Consistent with this role, RMD localizes at the tip of the rice pollen tube, which is essential for pollen tube growth and polarity as well as F-actin organization. Furthermore, the direction and characteristics of the RMD-guided F-actin array positively regulate the deposition of cell wall components and the pattern and velocity of cytoplasmic streaming during rice pollen tube growth. Collectively, our results suggest that RMD is essential for the spatial regulation of pollen tube growth via modulating F-actin organization and array orientation in rice. This work provides insights into tip-focused cell growth and polarity. PMID- 29581179 TI - Selective Targeting of Mobile mRNAs to Plasmodesmata for Cell-to-Cell Movement. AB - Many plant mRNAs move from cell to cell or long distance to execute non-cell autonomous functions. These mobile mRNAs traffic through the phloem to regulate many developmental processes, but despite the burgeoning discovery of mobile mRNAs, little is known about the mechanism underlying the intracellular sorting of these mRNAs. Here, we exploited a fluorescence-based mRNA labeling system, using the bacteriophage coat protein MS2, fused to GFP (MS2-GFP) and an MS2 recognition site in the RNA of interest, to visualize the intracellular trafficking of mobile mRNAs in living plant cells of Nicotiana benthamiana We first improved this system by using the nuclear localization sequence from FD, which substantially reduced the fluorescent background of MS2-GFP in the cytoplasm. The modified system allowed us to observe the cytoplasmic fluorescent foci dependent on MS2-binding sites. Coexpressing the MS2-GFP system with a virus movement protein, which is a plasmodesmata (PD)-localized nonspecific RNA-binding protein, targeted cytoplasmic fluorescent foci to the PD, suggesting that the cytoplasmic fluorescent foci contain mRNA and MS2-GFP. Our ex vivo RNA imaging revealed that mobile but not nonmobile mRNAs were selectively targeted to PD. Real-time images of intracellular translocation revealed that the translocation of mRNA and organelles in the transvacuolar strands may be governed by the same mechanism. Our study suggests that PD targeting of mRNA is a selective step in determining mRNA cell-to-cell movement of mRNAs. PMID- 29581180 TI - Soft X-Ray Imaging of Cellular Carbon and Nitrogen Distributions in Heterocystous Cyanobacteria. AB - Soft x-ray microscopy (SXM) is a minimally invasive technique for single-cell high-resolution imaging as well as the visualization of intracellular distributions of light elements such as carbon, nitrogen, and oxygen. We used SXM to observe photosynthesis and nitrogen fixation in the filamentous cyanobacterium Anabaena sp. PCC 7120, which can form heterocysts during nitrogen starvation. Statistical and spectroscopic analyses from SXM images around the K-absorption edge of nitrogen revealed a significant difference in the carbon-to-nitrogen (C/N) ratio between vegetative cells and heterocysts. Application of this analysis to soft x-ray images of Anabaena sp. PCC 7120 revealed inhomogenous C/N ratios in the cells. Furthermore, soft x-ray tomography of Anabaena sp. PCC 7120 revealed differing cellular C/N ratios, indicating different carbon and nitrogen distributions between vegetative cells and heterocysts in three dimensions. PMID- 29581181 TI - Sports Sponsorships of Food and Nonalcoholic Beverages. AB - BACKGROUND: Food and nonalcoholic beverage companies spend millions of dollars on professional sports sponsorships, yet this form of marketing is understudied. These sponsorships are valuable marketing tools but prompt concerns when unhealthy products are associated with popular sports organizations, especially those viewed by youth. METHODS: This descriptive study used Nielsen audience data to select 10 sports organizations with the most 2-17 year old viewers of 2015 televised events. Sponsors of these organizations were identified and assigned to product categories. We identified advertisements promoting food and/or nonalcoholic beverage sponsorships on television, YouTube, and sports organization Web sites from 2006 to 2016, and the number of YouTube advertisement views. The nutritional quality of advertised products was assessed. RESULTS: Youth watched telecasts associated with these sports organizations over 412 million times. These organizations had 44 food and/or nonalcoholic beverage sponsors (18.8% of sponsors), second to automotive sponsors (n = 46). The National Football League had the most food and/or nonalcoholic beverage sponsors (n = 10), followed by the National Hockey League (n = 7) and Little League (n = 7). We identified 273 advertisements that featured food and/or nonalcoholic beverage products 328 times and product logos 83 times (some advertisements showed multiple products). Seventy-six percent (n = 132) of foods had unhealthy nutrition scores, and 52.4% (n = 111) of nonalcoholic beverages were sugar sweetened. YouTube sponsorship advertisements totaled 195.6 million views. CONCLUSIONS: Sports sponsorships are commonly used to market unhealthy food and nonalcoholic beverages, exposing millions of consumers to these advertisements. PMID- 29581182 TI - Pediatric Hoverboard and Skateboard Injuries. AB - OBJECTIVES: To investigate the characteristics of hoverboard injuries compared with skateboard injuries in children presenting to US emergency departments (EDs). METHODS: Data regarding hoverboard and skateboard injuries in children <18 years of age were obtained from the National Electronic Injury Surveillance System for calendar years 2015 and 2016. Data included demographics, body regions injured, and ED disposition. RESULTS: There were an estimated 26 854 hoverboard and 121 398 skateboard injuries treated in US EDs between 2015 and 2016. The mean and median ages for hoverboard and skateboard injuries were 11 and 13 years, respectively. In both groups, boys were more commonly injured. The majority of hoverboard injuries occurred at home, whereas skateboard injuries occurred on the street. The wrists were the most common injured body part, and fractures were the most common diagnosis in both groups. The majority of patients in both groups were discharged from the hospital. Approximately 3% of the patients with skateboard injuries and hoverboard injuries were admitted to the hospital. CONCLUSIONS: The distribution of injuries among hoverboard riders and skateboarders was similar. Fractures, contusions, and sprains and/or strains were the most common types of injuries in both riders. However, there was a higher number of sprains and/or strains in skateboarders when compared with hoverboard users. This difference may be attributed to the way users ride these boards. Fractures were the most common reason for hospital admission for both toys. By elucidating the characteristics of hoverboard injuries, preventive measures can be implemented to decrease the incidence of these injuries as well as ED visits. PMID- 29581183 TI - How cells sense their own shape - mechanisms to probe cell geometry and their implications in cellular organization and function. AB - Cells come in a variety of shapes that most often underlie their functions. Regulation of cell morphogenesis implies that there are mechanisms for shape sensing that still remain poorly appreciated. Global and local cell geometry features, such as aspect ratio, size or membrane curvature, may be probed by intracellular modules, such as the cytoskeleton, reaction-diffusion systems or molecular complexes. In multicellular tissues, cell shape emerges as an important means to transduce tissue-inherent chemical and mechanical cues into intracellular organization. One emergent paradigm is that cell-shape sensing is most often based upon mechanisms of self-organization, rather than determinism. Here, we review relevant work that has elucidated some of the core principles of how cellular geometry may be conveyed into spatial information to guide processes, such as polarity, signaling, morphogenesis and division-plane positioning. PMID- 29581184 TI - Loss of the hematopoietic stem cell factor GATA2 in the osteogenic lineage impairs trabecularization and mechanical strength of bone. AB - The transcription factor GATA2 is required for expansion and differentiation of hematopoietic stem cells (HSCs). In mesenchymal stem cells (MSCs) GATA2 blocks adipogenesis, but its biological relevance and underlying genomic events are unknown. We report a dual function of GATA2 in bone homeostasis. GATA2 in MSCs binds near genes involved in skeletal system development and co-localizes with motifs for FOX and HOX transcription factors, known regulators of skeletal development. Ectopic GATA2 blocks osteoblastogenesis by interfering with SMAD1/5/8 activation. MSC-specific deletion of GATA2 in mice increases numbers and differentiation capacity of bone-derived precursors, resulting in elevated bone formation. Surprisingly, MSC-specific GATA2 deficiency impairs trabecularization and mechanical strength of bone, involving reduced MSC expression of the osteoclast inhibitor osteoprotegerin and increased osteoclast numbers. Thus, GATA2 affects bone turnover via MSC-autonomous and indirect effects. By regulating bone trabecularization, GATA2 expression in the osteogenic lineage may contribute to the anatomical and cellular microenvironment of the HSC niche required for hematopoiesis. PMID- 29581185 TI - The C-Terminal Extension Unique to the Long Isoform of the Shelterin Component TIN2 Enhances Its Interaction with TRF2 in a Phosphorylation- and Dyskeratosis Congenita Cluster-Dependent Fashion. AB - TIN2 is central to the shelterin complex, linking the telomeric proteins TRF1 and TRF2 with TPP1/POT1. Mutations in TINF2, which encodes TIN2, that are found in dyskeratosis congenita (DC) result in very short telomeres and cluster in a region shared by the two TIN2 isoforms, TIN2S (short) and TIN2L (long). Here we show that TIN2L, but not TIN2S, is phosphorylated. TRF2 interacts more with TIN2L than TIN2S, and both the DC cluster and phosphorylation promote this enhanced interaction. The binding of TIN2L, but not TIN2S, is affected by TRF2-F120, which is also required for TRF2's interaction with end processing factors such as Apollo. Conversely, TRF1 interacts more with TIN2S than with TIN2L. A DC associated mutation further reduces TIN2L-TRF1, but not TIN2S-TRF1, interaction. Cells overexpressing TIN2L or phosphomimetic TIN2L are permissive to telomere elongation, whereas cells overexpressing TIN2S or phosphodead TIN2L are not. Telomere lengths are unchanged in cell lines in which TIN2L expression has been eliminated by clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9-mediated mutation. These results indicate that TIN2 isoforms are biochemically and functionally distinguishable and that shelterin composition could be fundamentally altered in patients with TINF2 mutations. PMID- 29581186 TI - The phosphatase PTPL1 is required for PTEN-mediated regulation of apical membrane size. AB - PTEN is a tumor suppressor frequently lost in epithelial malignancies. Part of the tumor suppressive properties of PTEN is attributed to its function in cell polarization and consequently its role in maintaining epithelial tissue integrity. However, surprisingly little is known about the function and regulation of PTEN during epithelial cell polarization.We used CRISPR/Cas9 mediated gene disruption to delete PTEN in intestinal epithelial Ls174T:W4 cells, which upon differentiation form a microvilli-covered apical membrane (brush border) on a part of the cell cortex, independent of cell-cell junctions. We show that loss of PTEN results in the formation of a larger brush border that, in a fraction of the cells, even spans the entire plasma membrane, revealing that PTEN functions in the regulation of apical membrane size. Depletion of the phosphatase PTPL1 resulted in a similar defect. PTPL1 interacts with PTEN, and this interaction is necessary for apical membrane enrichment of PTEN. Importantly, phosphatase activity of PTPL1 is not required, indicating that PTPL1 functions as an anchor protein in this process.Our work thus demonstrates a novel function for PTEN during cell polarization in controlling apical membrane size and identifies PTPL1 as a critical apical membrane anchor for PTEN in this process. PMID- 29581187 TI - RBM4 Modulates Radial Migration via Alternative Splicing of Dab1 during Cortex Development. AB - The RNA-binding motif 4 (RBM4) protein participates in cell differentiation via its role in regulating the expression of tissue-specific or developmentally regulated mRNA splice isoforms. RBM4 is expressed in embryonic brain during development; it is initially enriched in the ventricular zone/subventricular zone and subsequently distributed throughout the cerebral cortex. Rbm4a knockout brain exhibited delayed migration of late-born neurons. Using in utero electroporation, we confirmed that knockdown of RBM4 impaired cortical neuronal migration. RNA immunoprecipitation with high-throughput sequencing identified Disabled-1 (Dab1), which encodes a critical reelin signaling adaptor, as a potential target of RBM4. Rbm4a knockout embryonic brain showed altered Dab1 isoform ratios. Overexpression of RBM4 promoted the inclusion of Dab1 exons 7 and 8 (7/8), whereas its antagonist polypyrimidine tract-binding protein 1 (PTBP1) acted in an opposite manner. RBM4 directly counteracted the effect of PTBP1 on exon 7/8 selection. Finally, we showed that the full-length Dab1, but not exon 7/8-truncated Dab1, rescued neuronal migration defects in RBM4-depleted neurons, indicating that RBM4 plays a role in neuronal migration via modulating the expression of Dab1 splice isoforms. Our findings imply that RBM4 is necessary during brain development and that its deficiency may lead to developmental brain abnormality. PMID- 29581188 TI - New Insights into the Role of Zinc Acquisition and Zinc Tolerance in Group A Streptococcal Infection. AB - Zinc plays an important role in host innate immune function. However, the innate immune system also utilizes zinc starvation ("nutritional immunity") to combat infections. Here, we investigate the role of zinc import and export in the protection of Streptococcus pyogenes (group A Streptococcus; GAS), a Gram positive bacterial pathogen responsible for a wide spectrum of human diseases, against challenge from host innate immune defense. In order to determine the role of GAS zinc import and export during infection, we utilized zinc import (DeltaadcA DeltaadcAII) and export (DeltaczcD) deletion mutants in competition with the wild type in both in vitro and in vivo virulence models. We demonstrate that nutritional immunity is deployed extracellularly, while zinc toxicity is utilized upon phagocytosis of GAS by neutrophils. We also show that lysosomes and azurophilic granules in neutrophils contain zinc stores for use against intracellular pathogens. PMID- 29581189 TI - Identification and Characterization of the Neisseria gonorrhoeae MscS-Like Mechanosensitive Channel. AB - Mechanosensitive channels are ubiquitous in bacteria and provide an essential mechanism to survive sudden exposure to a hypo-osmotic environment by the sensing and release of increased turgor pressure. No mechanosensitive channels have thus far been identified and characterized for the human-specific bacterial pathogen Neisseria gonorrhoeae In this study, we identified and characterized the N. gonorrhoeae MscS-like mechanosensitive channel (Ng-MscS). Electrophysiological analyses by the patch clamp method showed that Ng-MscS is stretch activated and contains pressure-dependent gating properties. Further mutagenesis studies of critical residues forming the hydrophobic vapor lock showed that gain-of-function mutations in Ng-MscS inhibited bacterial growth. Subsequent analysis of the function of Ng-MscS in N. gonorrhoeae by osmotic down-shock assays revealed that the survival of Ng-mscS deletion mutants was significantly reduced compared with that of wild-type strains, while down-shock survival was restored upon the ectopic complementation of mscS Finally, to investigate whether Ng-MscS is important for N. gonorrhoeae during infections, competition assays were performed by using a murine vaginal tract infection model. Ng-mscS deletion mutants were outcompeted by N. gonorrhoeae wild-type strains for colonization and survival in this infection model, highlighting that Ng-MscS contributes to in vivo colonization and survival. Therefore, Ng-MscS might be a promising target for the future development of novel antimicrobials. PMID- 29581190 TI - Candida albicans White-Opaque Switching Influences Virulence but Not Mating during Oropharyngeal Candidiasis. AB - The capacity of Candida albicans to switch reversibly between the white phenotype and the opaque phenotype is required for the fungus to mate. It also influences virulence during hematogenously disseminated candidiasis. We investigated the roles of the mating type loci (MTL) and white-opaque switching in the capacity of C. albicans to mate in the oropharynx and cause oropharyngeal candidiasis (OPC). When immunosuppressed mice were orally infected with mating-competent opaque a/a and alpha/alpha cells either alone or mixed with white cells, no detectable mating occurred, indicating that the mating frequency was less than 1.6 * 10-6 Opaque cells were also highly attenuated in virulence; they either were cleared from the oropharynx or switched to the white phenotype during OPC. Although there were strain-to-strain differences in the virulence of white cells, they were consistently more virulent than opaque cells. In vitro studies indicated that relative to white cells, opaque cells had decreased capacity to invade and damage oral epithelial cells. The reduced invasion of at least one opaque strain was due to reduced surface expression of the Als3 invasin and inability to activate the epidermal growth factor receptor, which is required to stimulate the epithelial cell endocytic machinery. These results suggest that mating is a rare event during OPC because opaque cells have reduced capacity to invade and damage the epithelial cells of the oral mucosa. PMID- 29581191 TI - Kingella kingae Surface Polysaccharides Promote Resistance to Human Serum and Virulence in a Juvenile Rat Model. AB - Kingella kingae is a Gram-negative coccobacillus that is increasingly being recognized as an important cause of invasive disease in young children. The pathogenesis of K. kingae disease begins with colonization of the oropharynx, followed by invasion of the bloodstream, survival in the intravascular space, and dissemination to distant sites. Recent studies have revealed that K. kingae produces a number of surface factors that may contribute to the pathogenic process, including a polysaccharide capsule and an exopolysaccharide. In this study, we observed that K. kingae was highly resistant to the bactericidal effects of human serum complement. Using mutant strains deficient in expression of capsule, exopolysaccharide, or both in assays with human serum, we found that elimination of both capsule and exopolysaccharide was required for efficient binding of IgG, IgM, C4b, and C3b to the bacterial surface and for complement mediated killing. Abrogation of the classical complement pathway using EGTA treated human serum restored survival to wild-type levels by the mutant lacking both capsule and exopolysaccharide, demonstrating that capsule and exopolysaccharide promote resistance to the classical complement pathway. Consistent with these results, loss of both capsule and exopolysaccharide eliminated invasive disease in juvenile rats with an intact complement system but not in rats lacking complement. Based on these observations, we conclude that the capsule and the exopolysaccharide have important redundant roles in promoting survival of K. kingae in human serum. Each of these surface factors is sufficient by itself to fully prevent serum opsonin deposition and complement-mediated killing of K. kingae, ultimately facilitating intravascular survival and promoting K. kingae invasive disease. PMID- 29581192 TI - Characterization of Individual Human Antibodies That Bind Pertussis Toxin Stimulated by Acellular Immunization. AB - Despite high vaccination rates, the incidence of whooping cough has steadily been increasing in developing countries for several decades. The current acellular pertussis (aP) vaccines all include the major protective antigen pertussis toxin (PTx) and are safer, but they appear to be less protective than infection or older, whole-cell vaccines. To better understand the attributes of individual antibodies stimulated by aP, we isolated plasmablast clones recognizing PTx after booster immunization of two donors. Five unique antibody sequences recognizing native PTx were recovered and expressed as recombinant human IgG1 antibodies. The antibodies all bind different epitopes on the PTx S1 subunit, B oligomer, or S1-B subunit interface, and just one clone neutralized PTx in an in vitro assay. To better understand the epitopes bound by the nonneutralizing S1-subunit antibodies, comprehensive mutagenesis with yeast display provided a detailed map of the epitope recognized by antibodies A8 and E12. Residue R76 is required for antibody A8 binding and is present on the S1 surface but is only partially exposed in the holotoxin, providing a structural explanation for A8's inability to neutralize holotoxin. The B-subunit-specific antibody D8 inhibited PTx binding to a model receptor and neutralized PTx in vitro as well as in an in vivo leukocytosis assay. This is the first study, to our knowledge, to identify individual human antibodies stimulated by the acellular pertussis vaccine and demonstrates the feasibility of using these approaches to address outstanding issues in pertussis vaccinology, including mechanisms of accelerated waning of protective immunity despite repeated aP immunization.

AB - The gram-negative obligate intracellular bacterium Rickettsia parkeri is an emerging tick-borne human pathogen. Recently, R. parkeri Sca2 and RickA have been implicated in adherence and actin-based motility in vertebrate host cell infection models; however, the rickettsial-derived factors essential to tick infection are unknown. Using R. parkeri mutants lacking functional Sca2 or RickA to compare actin polymerization, replication, and cell-to-cell spread in vitro, similar phenotypes in tick and mammalian cells were observed. Specifically, actin polymerization in cultured tick cells is controlled by the two separate proteins in a time-dependent manner. To assess the role of Sca2 and RickA in dissemination in the tick host, Rickettsia-free Amblyomma maculatum, the natural vector of R. parkeri, were exposed to the wild-type, R. parkeri rickA::tn, or R. parkeri sca2::tn bacteria and individual tick tissues including salivary glands, midguts, ovaries, and hemolymph were analyzed at 12 hours and after continued bloodmeal acquisition for 3 or 7 days post-exposure. Initially, ticks exposed to wild-type R. parkeri had the highest rickettsial load across all organs; however, rickettsial loads decreased and wild-type rickettsiae were cleared in the ovaries at seven days post-exposure. In contrast, ticks exposed to R. parkeri rickA::tn or R. parkeri sca2::tn had comparatively lower rickettsial loads, but bacteria persisted in all organs for seven days. These data suggest that, while RickA and Sca2 function in actin polymerization in tick cells, the absence of these proteins did not change dissemination patterns with the tick vector. PMID- 29581193 TI - Cysteamine, an Endogenous Aminothiol, and Cystamine, the Disulfide Product of Oxidation, Increase Pseudomonas aeruginosa Sensitivity to Reactive Oxygen and Nitrogen Species and Potentiate Therapeutic Antibiotics against Bacterial Infection. AB - Cysteamine is an endogenous aminothiol produced in mammalian cells as a consequence of coenzyme A metabolism through the activity of the vanin family of pantetheinase ectoenzymes. It is known to have a biological role in oxidative stress, inflammation, and cell migration. There have been several reports demonstrating anti-infective properties targeting viruses, bacteria, and even the malarial parasite. We and others have previously described broad-spectrum antimicrobial and antibiofilm activities of cysteamine. Here, we go further to demonstrate redox-dependent mechanisms of action for the compound and how its antimicrobial effects are, at least in part, due to undermining bacterial defenses against oxidative and nitrosative challenges. We demonstrate the therapeutic potentiation of antibiotic therapy against Pseudomonas aeruginosa in mouse models of infection. We also demonstrate potentiation of many different classes of antibiotics against a selection of priority antibiotic-resistant pathogens, including colistin (often considered an antibiotic of last resort), and we discuss how this endogenous antimicrobial component of innate immunity has a role in infectious disease that is beginning to be explored and is not yet fully understood. PMID- 29581195 TI - Serine-Rich Repeat Adhesins Mediate Shear-Enhanced Streptococcal Binding to Platelets. AB - The binding of bacteria to platelets is thought to be a central event in the pathogenesis of infective endocarditis. The serine-rich repeat (SRR) glycoproteins of viridans group streptococci have been shown to mediate platelet binding in vitro and to contribute to virulence in animal models. However, it is not known whether SRR adhesins can mediate streptococcal binding under the high fluidic shear stress conditions present on the endocardial surface. We found that three streptococcal SRR adhesins (GspB, Hsa, and SrpA) with differing structures and sialoglycan binding specificities nevertheless exhibited similar biomechanical properties. All three adhesins mediated shear-enhanced streptococcal binding to immobilized platelets through the platelet receptor GPIbalpha. Shear-enhanced adhesion was manifested in three ways. First, the number of circulating streptococci binding via SRR adhesins to immobilized platelet receptors peaked at 1 dyn/cm2 Second, bound streptococci switched from weak rolling to strong stationary adhesion as shear stress increased to 10 dyn/cm2 Third, while a few streptococci detached each time the flow was increased, the majority of streptococci bound to platelets remained firmly attached through 20 to 80 dyn/cm2 (shear levels typical of arteries and the endocardium). Thus, all three adhesins mediated shear-enhanced streptococcal binding to platelets under the flow conditions found in heart valves. The ability of the SRR adhesins to mediate shear-enhanced binding strongly suggests that they form catch bonds that are activated by tensile force and provides a mechanism for the selective targeting of bacteria to platelet receptors immobilized on the endocardial surface. PMID- 29581196 TI - Immunity against the Obligate Intracellular Bacterial Pathogen Rickettsia australis Requires a Functional Complement System. AB - The complement system has a well-defined role in deterring blood-borne infections. However, complement is not entirely efficacious, as several bacterial pathogens, including some obligate intracellular pathogens, have evolved mechanisms for resistance. It is presumed that obligate intracellular bacteria evade complement attack by residing within a host cell; however, recent studies have challenged this presumption. Here, we demonstrate that the complement system is activated during infection with the obligate intracellular bacterium Rickettsia australis and that genetic ablation of complement increases susceptibility to infection. Interaction of Rickettsia australis with serum-borne complement leads to activation of the complement cascade, producing three effector mechanisms that could negatively influence R. australis. The C9 dependent membrane attack complex can lead to deposition of a bacteriolytic membrane pore on the bacteria, but this system does not contribute to control of rickettsial infection. Similarly, complement receptor (CR1/2)-dependent opsonophagocytosis may lead to engulfment and killing of the bacteria, but this system is also dispensable for immunity. Nevertheless, intact complement is essential for naturally acquired and antibody-mediated immunity to Rickettsia infection. Comparison of infection in mice lacking the central complement protein C3 with infection in their wild-type counterparts demonstrated decreases in gamma interferon (IFN-gamma) production, IgG secretion, and spleen hyperplasia in animals lacking complement. The correlation between loss of secondary immune functions and loss of complement indicates that the proinflammatory signaling components of the complement system, and not membrane attack complex or opsonophagocytosis, contribute to the immune response to this pathogen. PMID- 29581197 TI - Tumor Necrosis Factor Alpha Antagonism Reveals a Gut/Lung Axis That Amplifies Regulatory T Cells in a Pulmonary Fungal Infection. AB - Tumor necrosis factor (TNF) antagonists are popular therapies for inflammatory diseases. These agents enhance the numbers and function of regulatory T cells (Tregs), which are important in controlling inflammatory diseases. However, elevated Treg levels increase susceptibility to infections, including histoplasmosis. We determined the mechanism by which Tregs expand in TNF neutralized mice infected with Histoplasma capsulatum Lung CD11c+ CD11b+ dendritic cells (DCs), but not alveolar macrophages, from H. capsulatum-infected mice treated with anti-TNF induced a higher percentage of Tregs than control DCs in vitro CD11b+ CD103+ DCs, understood to be unique to the intestines, were augmented in lungs with anti-TNF treatment. In the absence of this subset, DCs from anti-TNF-treated mice failed to amplify Tregs in vitro CD11b+ CD103+ DCs from TNF-neutralized mice displayed higher retinaldehyde dehydrogenase 2 (RALDH2) gene expression, and CD11b+ CD103+ RALDH+ DCs exhibited greater enzyme activity. To determine if CD11b+ CD103+ DCs migrated from gut to lung, fluorescent beads were delivered to the gut via oral gavage, and the lungs were assessed for bead containing DCs. Anti-TNF induced migration of CD11b+ CD103+ DCs from the gut to the lung that enhanced the generation of Tregs in H. capsulatum-infected mice. Therefore, TNF neutralization promotes susceptibility to pulmonary H. capsulatum infection by promoting a gut/lung migration of DCs that enhances Tregs. PMID- 29581198 TI - Care home services at the vanguard: a qualitative study exploring stakeholder views on the development and evaluation of novel, integrated approaches to enhancing healthcare in care homes. AB - OBJECTIVES: To explore stakeholders' understanding of novel integrated approaches to enhancing care in care homes (a care home 'vanguard') and identify priorities for evaluation. DESIGN: A qualitative study, using semistructured interviews with commissioners and service providers to/within care homes, and third sector organisations with thematic analysis. SETTING: A Clinical Commissioning Group (CCG) area in England. PARTICIPANTS: Thirty interviewees from care homes, the National Health Service (NHS; England) and local authority, third sector (10 care home managers, 5 general practitioners, 4 CCG employees, 4 local authority employees, 1 national (NHS England) vanguard lead, 2 specialist nurses, 2 geriatricians, 1 third sector and 1 health manager). RESULTS: Four higher level themes emerged from the data: understanding of proposed changes, communication, evaluation of outcome measures of success, and trust and complexity. The vision for the new programme was shared by stakeholders, with importance attached to equitable access to high-quality care. Support for the programme was described as being 'the right thing to do', inferring a moral imperative. However, the practical implications of key aspects, such as integrated working, were not clearly understood and the programme was perceived by some as being imposed, top down, from the health service. Barriers and facilitators to change were identified across themes of communication, outcomes, trust and complexity. Importance was attached to the measurement of intangible aspects of success, such as collaboration. Interviewees understood that outcome-based commissioning was one element of the new programme, but discussion of their aspirations and practices revealed values and beliefs more compatible with a system based on trust. CONCLUSIONS: Innovation in service delivery requires organisations to adopt common priorities and share responsibility for success. The vanguard programme is working to ensure health and local authorities have this commitment, but engaging care homes that may feel isolated from the welfare system needs sustained dialogue over the longer term. Evaluation of the programme needs to measure what is important to stakeholders, and not focus too closely on resource consumption. PMID- 29581199 TI - Is exposure to ionising radiation associated with childhood cardiac arrhythmia in the Russian territories contaminated by the Chernobyl fallout? A cross-sectional population-based study. AB - OBJECTIVE: To investigate childhood cardiac arrhythmia and chronic exposure to caesium-137 (137Cs) resulting from the Chernobyl accident. DESIGN: Prospective cross-sectional study using exposed/unexposed design conducted in the Bryansk region from May 2009 to May 2013 on children selected on the basis of 137Cs soil deposition: control territories ([137Cs]<37 kBq per square metre, where children were considered as unexposed) and contaminated territories ([137Cs]>555 kBq per square metre, where children were considered as exposed). SETTING: Russian territories affected by the Chernobyl fallout (Bryansk region). PARTICIPANTS: This cross-sectional study included 18 152 children aged 2-18 years and living in the Bryansk region (Russia). MAIN OUTCOME MEASURES: All children received three medical examinations (ECG, echocardiography and 137Cs whole-body activity measurement) and some of them were given with a 24-hour Holter monitoring and blood tests. RESULTS: Cardiac arrhythmia was diagnosed in 1172 children living in contaminated territories and 1354 children living in control territories. The crude prevalence estimated to 13.3% in contaminated territories was significantly lower than in control territories with 15.2% over the period 2009-2013 (P<0.001). Considering 137Cs whole-body burden as exposure, cardiac arrhythmia was found in 449 contaminated children and 2077 uncontaminated children, corresponding to an estimated crude prevalence of 14.5% and 14.2%, respectively, which does not differ significantly (P=0.74). Also, we investigated the association between territory, exposure to 137Cs and cardiac arrhythmia: the adjusted OR was not significant (0.90 with 95% CI 0.81 to 1.00; P=0.06) for the territory. For 137Cs whole-body burden, the ORs close to 1 did not reach statistical significance (P for trend=0.97). CONCLUSION: This study does not observe an association between cardiac arrhythmia and 137Cs deposition levels in the Bryansk region exposed to Chernobyl fallout. The suspected increase of cardiac arrhythmia in children exposed to Chernobyl fallout is not confirmed. PMID- 29581200 TI - Effectiveness of the 13-valent pneumococcal conjugate vaccine against adult pneumonia in Italy: a case-control study in a 2-year prospective cohort. AB - OBJECTIVES: Current strategies to prevent adult pneumococcal disease have been recently reviewed in Italy. We did a postlicensure study to estimate the direct vaccine effectiveness (VE) of the 13-valent pneumococcal conjugate vaccine (PCV13) against adult pneumococcal community-acquired pneumonia (pCAP). STUDY DESIGN: Between 2013 and 2015, a 2-year prospective cohort study of adults with CAP was conducted in the Apulia region of Italy where the average vaccine uptake of PCV13 was 32% among adults >=65 years. The test-negative design was used to estimate VE against all episodes of confirmed pCAP and vaccine-type (VT)-CAP. VE in a subgroup of patients managed in the community was also estimated using a matched case-control design. VE was calculated as one minus the OR times 100%. RESULTS: The overall VE of PCV13 was 33.2% (95% CI -106.6% to 82%) against pCAP irrespective of serotype and 38.1% (95% CI -131.9% to 89%) against VT-CAP in the cohort of adults >=65 years. The VE was 42.3% (95% CI -244.1% to 94.7%) against VT-CAP in the age group at higher vaccine uptake. For the subgroup of cases managed in the community, the overall VE against disease due to any pneumococcal strain was 88.1% (95% CI 4.2% to 98.5%) and 91.7% (95% CI 13.1% to 99.2%) when we controlled for underlying conditions. CONCLUSIONS: Although our results are non significant, PCV13 promises to be effective against all confirmed pCAP already with modest levels of uptake in the population of adults >=65 years of age. Larger studies are needed to confirm the direct vaccine benefits. PMID- 29581201 TI - Voices from low-income and middle-income countries: a systematic review protocol of primary healthcare interventions within public health systems addressing intimate partner violence against women. AB - INTRODUCTION: Intimate partner violence (IPV) considerably harms the health, safety and well-being of women. In response, public health systems around the globe have been gradually implementing strategies. In particular, low-income and middle-income countries (LMIC) have been developing innovative interventions in primary healthcare (PHC) addressing the problem. This paper describes a protocol for a systematic review of studies addressing the impacts and outcomes of PHC centre interventions addressing IPV against women from LMIC. METHODS AND ANALYSIS: A systematic search for studies will be conducted in African Index Medicus, Africa Portal Digital Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Index Medicus for the Southeast Asia Region, IndMed, Latin American and Caribbean Health Science Literature Database (LILACS), Medecins Sans Frontieres, MEDLINE, Minority Health and Health Equity Archive, ProQuest, PsycINFO, Scientific Electronic Library Online, (SciELO) and Social Policy and Practice. Studies will be in English, Spanish and Portuguese, published between 2007 and 2017, addressing IPV against women from LMIC, whose data quantitatively report on the impacts and outcomes for survivors and/or workers and/or public health systems preintervention and postintervention. Two trilingual reviewers will independently screen for study eligibility and data extraction, and a librarian will cross-check for compliance. Risk of bias and quality assessment of studies will be measured according to: (1) the Cochrane Collaboration's tool for assessing risk of bias for randomised controlled trials and (2) the Methodological Index for Non-Randomised Studies (MINORS). Data will be analysed and summarised using meta-analysis and narrative description of the evidence across studies. This systematic review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols(PRISMA P) guidelines. ETHICS AND DISSEMINATION: This systematic review will be based on published studies, thus not requiring ethical approval. Findings will be presented in conferences and published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017069261. PMID- 29581202 TI - Real-world effects of medications for chronic obstructive pulmonary disease: protocol for a UK population-based non-interventional cohort study with validation against randomised trial results. AB - INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a progressive disease affecting 3 million people in the UK, in which patients exhibit airflow obstruction that is not fully reversible. COPD treatment guidelines are largely informed by randomised controlled trial results, but it is unclear if these findings apply to large patient populations not studied in trials. Non interventional studies could be used to study patient groups excluded from trials, but the use of these studies to estimate treatment effectiveness is in its infancy. In this study, we will use individual trial data to validate non interventional methods for assessing COPD treatment effectiveness, before applying these methods to the analysis of treatment effectiveness within people excluded from, or under-represented in COPD trials. METHODS AND ANALYSIS: Using individual patient data from the landmark COPD Towards a Revolution in COPD Health (TORCH) trial and validated methods for detecting COPD and exacerbations in routinely collected primary care data, we will assemble a cohort in the UK Clinical Practice Research Datalink (selecting people between 1 January 2004 and 1 January 2017) with similar characteristics to TORCH participants and test whether non-interventional data can generate comparable results to trials, using cohort methodology with propensity score techniques to adjust for potential confounding. We will then use the methodological template we have developed to determine risks and benefits of COPD treatments in people excluded from TORCH. Outcomes are pneumonia, COPD exacerbation, mortality and time to treatment change. Groups to be studied include the elderly (>80 years), people with substantial comorbidity, people with and without underlying cardiovascular disease and people with mild COPD. ETHICS AND DISSEMINATION: Ethical approval has been granted by the London School of Hygiene & Tropical Medicine Ethics Committee (Ref: 11997). The study has been approved by the Independent Scientific Advisory Committee of the UK Medicines and Healthcare Products Regulatory Agency (protocol no. 17_114R). An application to use the TORCH trial data made to clinicalstudydatarequest.com has been approved. In addition to scientific publications, dissemination methods will be developed based on discussions with patient groups with COPD. PMID- 29581203 TI - Glycaemic control in type 2 diabetes patients and its predictors: a retrospective database study at a tertiary care diabetes centre in Ningbo, China. AB - OBJECTIVES: The objectives of the study were to assess glycaemic control in patients with type 2 diabetes (T2DM) at a tertiary care diabetes centre in Ningbo, China and to determine factors that independently predict their glycaemic control. DESIGN: Retrospective cross-sectional study using an existing database, the Diabetes Information Management System. SETTING: Tertiary care diabetes centre in Ningbo, China. PARTICIPANTS: The study included adult patients with T2DM, registered and received treatment at the diabetes centre for at least six consecutive months. The study inclusion criteria were satisfied by 1387 patients, from 1 July 2012 to 30 June 2017. PRIMARY OUTCOME MEASURE: Glycaemic control (poor was defined as glycated haemoglobin (HbA1c)>=7% or fasting blood glucose (FBG)>7.0 mmol/L). RESULTS: In terms of HbA1c and FBG, the 5-year period prevalence of poor glycaemic control was 50.3% and 57.3%, respectively. In terms of HbA1c and FBG, the odds of poor glycaemic control increased with the duration of T2DM (>1 to 2 years: OR 1.84, 95% CI 1.06 to 3.19; >2 to 4 years: 3.32, 1.88 to 5.85 and >4 years: 5.98, 4.09 to 8.75 and >1 to 2 years: 2.10, 1.22 to 3.62; >2 to 4 years: 2.48, 1.42 to 4.34 and >4 years: 3.34, 2.32 to 4.80) and were higher in patients residing in rural areas (1.68, 1.24 to 2.28 and 1.42, 1.06 to 1.91), with hyperlipidaemia (1.57, 1.12 to 2.19 and 1.68, 1.21 to 2.33), on diet, physical activity and oral hypoglycaemic drug (OHD) as part of their T2DM therapeutic regimen (1.80, 1.01 to 3.23 and 2.40, 1.36 to 4.26) and on diet, physical activity, OHD and insulin (2.47, 1.38 to 4.41 and 2.78, 1.58 to 4.92), respectively. CONCLUSIONS: More than half of patients with T2DM at the diabetes centre in Ningbo, China have poor glycaemic control, and the predictors of glycaemic control were identified. The study findings could be taken into consideration in future interventional studies aimed at improving glycaemic control in these patients. PMID- 29581204 TI - A cost of illness study of hypoglycaemic events in insulin-treated diabetes in the Netherlands. AB - OBJECTIVES: Patients with diabetes mellitus are at a risk for hypoglycaemia. Besides the burden of hypoglycaemia for patients, hypoglycaemia poses an economic burden to society. The aim of this study was to calculate the per patient societal costs of hypoglycaemia among patients with type1 diabetes (T1DM) and type 2 diabetes (T2DM) on insulin therapy in the Netherlands. METHODS: To calculate the costs of hypoglycaemia, data from the Global Hypoglycaemia Assessment Tool (HAT) study were used. Dutch patients were selected from the HAT study database and data regarding healthcare resource use, informal care use and productivity losses were combined with Dutch unit costs to calculate the per patient 4-week costs of patients experiencing hypoglycaemia. Besides these 4-week costs, costs per hypoglycaemic event were calculated by dividing the study population total 4-week costs by the total number of events in this period. RESULTS: Mean 4-week total costs of hypoglycaemia amounted to ?163 (SD, ?870) in T1DM and ?134 (SD, ?364) in T2DM. While productivity costs were the most important cost driver of hypoglycaemia in patients with T1DM (accounting for 72% of the total costs), costs of hypoglycaemia in patients with T2DM were almost entirely driven by costs within the healthcare sector (accounting for 98% of the total costs). Mean costs of a severe hypoglycaemic event were ?828 and ?508 in T1DM and T2DM, respectively, whereas mean costs of a non-severe event were almost zero. CONCLUSIONS: This study showed that the economic burden of severe hypoglycaemia is substantial. The prevention of hypoglycaemia could therefore not only reduce the burden for patients, but also the economic burden to society. PMID- 29581205 TI - A cross-sectional study of all clinicians' conflict of interest disclosures to NHS hospital employers in England 2015-2016. AB - OBJECTIVE: We set out to document how NHS trusts in the UK record and share disclosures of conflict of interest by their employees. DESIGN: Cross-sectional study of responses to a Freedom of Information Act request for Gifts and Hospitality Registers. SETTING: NHS Trusts (secondary/tertiary care organisations) in England. PARTICIPANTS: 236 Trusts were contacted, of which 217 responded. MAIN OUTCOME MEASURES: We assessed all disclosures for completeness and openness, scoring them for achieving each of five measures of transparency. RESULTS: 185 Trusts (78%) provided a register. 71 Trusts did not respond within the 28 day time limit required by the FoIA. Most COI registers were incomplete by design, and did not contain the information necessary to assess conflicts of interest. 126/185 (68%) did not record the names of recipients. 47/185 (25%) did not record the cash value of the gift or hospitality. Only 31/185 registers (16%) contained the names of recipients, the names of donors, and the cash amounts received. 18/185 (10%) contained none of: recipient name, donor name, and cash amount. Only 15 Trusts had their disclosure register publicly available online (6%). We generated a transparency index assessing whether each Trust met the following criteria: responded on time; provided a register; had a register with fields identifying donor, recipient, and cash amount; provided a register in a format that allowed further analysis; and had their register publicly available online. Mean attainment was 1.9/5; no NHS trust met all five criteria. CONCLUSION: Overall, recording of employees' conflicts of interest by NHS trusts is poor. None of the NHS Trusts in England met all transparency criteria. 19 did not respond to our FoIA requests, 51 did not provide a Gifts and Hospitality Register and only 31 of the registers provided contained enough information to assess employees' conflicts of interest. Despite obligations on healthcare professionals to disclose conflicts of interest, and on organisations to record these, the current system for logging and tracking such disclosures is not functioning adequately. We propose a simple national template for reporting conflicts of interest, modelled on the US 'Sunshine Act'. PMID- 29581206 TI - Validation of an algorithm to identify heart failure hospitalisations in patients with diabetes within the veterans health administration. AB - OBJECTIVES: We aimed to validate an algorithm using both primary discharge diagnosis (International Classification of Diseases Ninth Revision (ICD-9)) and diagnosis-related group (DRG) codes to identify hospitalisations due to decompensated heart failure (HF) in a population of patients with diabetes within the Veterans Health Administration (VHA) system. DESIGN: Validation study. SETTING: Veterans Health Administration-Tennessee Valley Healthcare System PARTICIPANTS: We identified and reviewed a stratified, random sample of hospitalisations between 2001 and 2012 within a single VHA healthcare system of adults who received regular VHA care and were initiated on an antidiabetic medication between 2001 and 2008. We sampled 500 hospitalisations; 400 hospitalisations that fulfilled algorithm criteria, 100 that did not. Of these, 497 had adequate information for inclusion. The mean patient age was 66.1 years (SD 11.4). Majority of patients were male (98.8%); 75% were white and 20% were black. PRIMARY AND SECONDARY OUTCOME MEASURES: To determine if a hospitalisation was due to HF, we performed chart abstraction using Framingham criteria as the referent standard. We calculated the positive predictive value (PPV), negative predictive value (NPV), sensitivity and specificity for the overall algorithm and each component (primary diagnosis code (ICD-9), DRG code or both). RESULTS: The algorithm had a PPV of 89.7% (95% CI 86.8 to 92.7), NPV of 93.9% (89.1 to 98.6), sensitivity of 45.1% (25.1 to 65.1) and specificity of 99.4% (99.2 to 99.6). The PPV was highest for hospitalisations that fulfilled both the ICD-9 and DRG algorithm criteria (92.1% (89.1 to 95.1)) and lowest for hospitalisations that fulfilled only DRG algorithm criteria (62.5% (28.4 to 96.6)). CONCLUSIONS: Our algorithm, which included primary discharge diagnosis and DRG codes, demonstrated excellent PPV for identification of hospitalisations due to decompensated HF among patients with diabetes in the VHA system. PMID- 29581207 TI - Cross-sectional associations of objectively assessed neighbourhood attributes with depressive symptoms in older adults of an ultra-dense urban environment: the Hong Kong ALECS study. AB - OBJECTIVES: This study aimed to examine the associations between objectively assessed neighbourhood environmental attributes and depressive symptoms in Hong Kong Chinese older adults and the moderating effects of neighbourhood environmental attributes on the associations between living arrangements and depressive symptoms. DESIGN: Cross-sectional observational study. SETTING: Hong Kong. PARTICIPANTS: 909 Hong Kong Chinese community dwellers aged 65+ years residing in preselected areas stratified by walkability and socioeconomic status. EXPOSURE AND OUTCOME MEASURES: Attributes of participants' neighbourhood environment were objectively assessed using geographic information systems and environmental audits. Depressive symptoms were measured using the Geriatric Depression Scale. RESULTS: Overall, pedestrian infrastructure (OR=1.025; P=0.008), connectivity (OR=1.039; P=0.002) and prevalence of public transport stops (OR=1.056; P=0.012) were positively associated with the odds of reporting depressive symptoms. Older adults living alone were at higher risk of reporting any depressive symptoms than those living with others (OR=1.497; P=0.039). This association was moderated by neighbourhood crowdedness, perceptible pollution, access to destinations and presence of people. Residing in neighbourhoods with lower levels of these attributes was associated with increased deleterious effects of living alone. Living in neighbourhoods with lower public transport density also increased the deleterious effects of living alone on the number of depressive symptoms. Those living alone and residing in neighbourhoods with higher levels of connectivity tended to report more depressive symptoms than their counterparts. CONCLUSIONS: The level of access to destinations and social networks across Hong Kong may be sufficiently high to reduce the risk of depressive symptoms in older adults. Yet, exposure to extreme levels of public transport density and associated traffic volumes may increase the risk of depressive symptoms. The provision of good access to a variety of destinations, public transport and public open spaces for socialising in the neighbourhood may help reduce the risk of depressive symptoms in older adults who live alone. PMID- 29581208 TI - Omega-3 polyunsaturated fatty acid supplementation for improving peripheral nerve health: protocol for a systematic review. AB - INTRODUCTION: Damage to peripheral nerves occurs in a variety of health conditions. Preserving nerve integrity, to prevent progressive nerve damage, remains a clinical challenge. Omega-3 polyunsaturated fatty acids (PUFAs) are implicated in the development and maintenance of healthy nerves and may be beneficial for promoting peripheral nerve health. The aim of this systematic review is to assess the effects of oral omega-3 PUFA supplementation on peripheral nerve integrity, including both subjective and objective measures of peripheral nerve structure and/or function. METHODS AND ANALYSIS: A systematic review of randomised controlled trials that have evaluated the effects of omega-3 PUFA supplementation on peripheral nerve assessments will be conducted. Comprehensive electronic database searches will be performed in Ovid MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), US National Institutes of Health Clinical Trials Registry and the WHO International Clinical Trials Registry Platform. The title, abstract and keywords of identified articles will be assessed for eligibility by two reviewers. Full-text articles will be obtained for all studies judged as eligible or potentially eligible; these studies will be independently assessed by two reviewers to determine eligibility. Disagreements will be resolved by consensus. Risk of bias assessment will be performed using the Cochrane Collaboration risk of bias tool to appraise the quality of included studies. If clinically meaningful, and there are a sufficient number of eligible studies, a meta-analysis will be conducted and a summary of findings table will be provided. ETHICS AND DISSEMINATION: This is a systematic review that will involve the analysis of previously published data, and therefore ethics approval is not required. A manuscript reporting the results of this systematic review will be published in a peer-reviewed journal and may also be presented at relevant scientific conferences.

PMID- 29581209 TI - Index coronary angiography use in Manitoba, Canada: a population-level descriptive analysis of First Nations and non-First Nations recipients. AB - OBJECTIVES: To investigate recipient characteristics and rates of index angiography among First Nations (FN) and non-FN populations in Manitoba, Canada. SETTING: Population-based, secondary analysis of provincial administrative health data. PARTICIPANTS: All adults 18 years or older who received an index angiogram between 2000/2001 and 2008/2009. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Descriptive statistics for age, sex, income quintile by rural and urban residency and Charlson Comorbidity Index for FN and non-FN recipients. (2) Annual index angiogram rates for FN and non-FN populations and among those rates of 'urgent' angiograms based on acute myocardial infarction (AMI)-related hospitalisations during the previous 7 days. (3) Proportions of people who did not receive an angiogram in the 20 years preceding an ischaemic heart disease (IHD) diagnosis or a cardiovascular death; stratified by age (<65 or >=65 years old). RESULTS: FN recipients were younger (56.3vs63.8 years; p<0.0001) and had higher Charlson Comorbidity scores (1.32vs0.78; p<0.001). During all years examined, index angiography rates were lower among FN people (2.67vs3.33 per 1000 population per year; p<0.001) with no notable temporal trends. Among the index angiogram recipients, a higher proportion was associated with an AMI-related hospitalisation in the FN group (28.8%vs25.0%; p<0.01) and in both groups rates significantly increased over time. FN people who died from cardiovascular disease or were older (65+years old) diagnosed with IHD were more likely to have received an angiogram in the preceding 20-30 years (17.8%vs12.5%; p<0.01 and 50.9%vs49.5%; p<0.03, respectively). FN people diagnosed with IHD who were under the age of 65 were less likely to have received an angiogram (47.8%vs53.1%; p<0.01) CONCLUSIONS: Index angiogram use differences are suggested between FN and non-FN populations, which may contribute to reported IHD disparities. Investigating factors driving these rates will determine any association between ethnicity and angiography services. PMID- 29581210 TI - A systematic assessment of Cochrane reviews and systematic reviews published in high-impact medical journals related to cancer. AB - OBJECTIVE: To compare cancer-related systematic reviews (SRs) published in the Cochrane Database of SRs (CDSR) and high-impact journals, with respect to type, content, quality and citation rates. DESIGN: Methodological SR with assessment and comparison of SRs and meta-analyses. Two authors independently assessed methodological quality using an Assessment of Multiple Systematic Reviews (AMSTAR)-based extraction form. Both authors independently screened search results, extracted content-relevant characteristics and retrieved citation numbers of the included reviews using the Clarivate Analytics Web of Science database. DATA SOURCES: Cancer-related SRs were retrieved from the CDSR, as well as from the 10 journals which publish oncological SRs and had the highest impact factors, using a comprehensive search in both the CDSR and MEDLINE. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included all cancer-related SRs and meta analyses published from January 2011 to May 2016. Methodological SRs were excluded. RESULTS: We included 346 applicable Cochrane reviews and 215 SRs from high-impact journals. Cochrane reviews consistently met more individual AMSTAR criteria, notably with regard to an a priori design (risk ratio (RR) 3.89; 95% CI 3.10 to 4.88), inclusion of the grey literature and trial registries (RR 3.52; 95% CI 2.84 to 4.37) in their searches, and the reporting of excluded studies (RR 8.80; 95% CI 6.06 to 12.78). Cochrane reviews were less likely to address questions of prognosis (RR 0.04; 95% CI 0.02 to 0.09), use individual patient data (RR 0.03; 95% CI 0.01 to 0.09) or be based on non-randomised controlled trials (RR 0.04; 95% CI 0.02 to 0.09). Citation rates of Cochrane reviews were notably lower than those for high-impact journals (Cochrane reviews: mean number of citations 6.52 (range 0-143); high-impact journal SRs: 74.45 (0-652)). CONCLUSIONS: When comparing cancer-related SRs published in the CDSR versus those published in high-impact medical journals, Cochrane reviews were consistently of higher methodological quality, but cited less frequently. PMID- 29581211 TI - Effects of vaccines in patients with sickle cell disease: a systematic review protocol. AB - INTRODUCTION: Sickle cell disease (SCD) is an inherited haematological disorder caused by a single point mutation (Glub6Val) that promotes polymerisation of haemoglobin S and sickling of erythrocytes. Inflammation, haemolysis, microvascular obstruction and organ damage characterise the highly variable clinical expression of SCD. People with SCD are at increased risk of severe infections, hence the need for vaccination against common disease-causing organisms in this population. We aim to review the evidence on the efficacy and safety of vaccines in people with SCD. METHODS AND ANALYSIS: The present systematic review will examine the current data as indexed in PubMed, CENTRAL, EMBASE and EBSCOHost. We will consult Strategic Advisory Group of Experts practice statements, conference abstracts, reference lists of relevant articles, WHO ICTRP trial registry and experts in the field. Two authors will independently screen search outputs, select studies, extract data and assess risk of bias; resolving discrepancies by discussion and consensus between the two authors or arbitration by a third author when necessary. We will perform a meta-analysis for clinically homogenous studies. Evidence from clinically diverse studies will be aggregated using narrative synthesis of the findings. In either case, we will use the GRADE approach to assess the strength of the available evidence. ETHICS AND DISSEMINATION: The study draws on data that are readily available in the public domain, hence no formal ethical review and approval is required. The findings of this review will be disseminated through conference presentations and a publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42018084051. PMID- 29581212 TI - Study protocol for a self-controlled cluster randomised trial of the Alert Program to improve self-regulation and executive function in Australian Aboriginal children with fetal alcohol spectrum disorder. AB - INTRODUCTION: While research highlights the benefits of early diagnosis and intervention for children with fetal alcohol spectrum disorders (FASD), there are limited data documenting effective interventions for Australian children living in remote communities. METHODS AND ANALYSIS: This self-controlled cluster randomised trial is evaluating the effectiveness of an 8-week Alert Program school curriculum for improving self-regulation and executive function in children living in remote Australian Aboriginal communities. Children in grades 1 6 attending any of the eight participating schools across the Fitzroy Valley in remote North-West Australia (N ~ 363) were invited to participate. Each school was assigned to one of four clusters with clusters randomly assigned to receive the intervention at one of four time points. Clusters two, three and four had extended control conditions where students received regular schooling before later receiving the intervention. Trained classroom teachers delivered the Alert Program to students in discrete, weekly, 1-hour lessons. Student outcomes were assessed at three time points. For the intervention condition, data collection occurred 2 weeks immediately before and after the intervention, with a follow-up 8 weeks later. For control conditions in clusters two to four, the control data collection matched that of the data collection for the intervention condition in the preceding cluster. The primary outcome is change in self-regulation. FASD diagnoses will be determined via medical record review after the completion of data collection. The results will be analysed using generalised linear mixed modelling and reported in accordance with Consolidated Standards of Reporting Trials (CONSORT) guidelines. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Western Australia (WA) (RA/4/1/7234), WA Aboriginal Health Ethics Committee (601) and WA Country Health Service (2015:04). The Kimberley Aboriginal Health Planning Forum Research Sub-Committee and WA Department of Education also provided approval. The results will be disseminated through peer-reviewed journals, conference presentations, the media and at forums. TRIAL REGISTRATION NUMBER: ACTRN12615000733572; Pre-results. PMID- 29581213 TI - Secreted Klotho Attenuates Inflammation-Associated Aortic Valve Fibrosis in Senescence-Accelerated Mice P1. AB - Senescence-accelerated mice P1 (SAMP1) is an aging model characterized by shortened lifespan and early signs of senescence. Klotho is an aging-suppressor gene. The purpose of this study is to investigate whether in vivo expression of secreted klotho (Skl) gene attenuates aortic valve fibrosis in SAMP1 mice. SAMP1 mice and age-matched (AKR/J) control mice were used. SAMP1 mice developed obvious fibrosis in aortic valves, namely fibrotic aortic valve disease. Serum level of Skl was decreased drastically in SAMP1 mice. Expression of MCP-1 (monocyte chemoattractant protein 1), ICAM-1 (intercellular adhesion molecule 1), F4/80, and CD68 was increased in aortic valves of SAMP1 mice, indicating inflammation. An increase in expression of alpha-smooth muscle actin (myofibroblast marker), transforming growth factorbeta-1, and scleraxis (a transcription factor of collagen synthesis) was also found in aortic valves of SAMP1 mice, suggesting that accelerated aging is associated with myofibroblast transition and collagen gene activation. We constructed adeno-associated virus 2 carrying mouse Skl cDNA for in vivo expression of Skl. Skl gene delivery effectively increased serum Skl of SAMP1 mice to the control level. Skl gene delivery inhibited inflammation and myofibroblastic transition in aortic valves and attenuated fibrotic aortic valve disease in SAMP1 mice. It is concluded that senescence-related fibrotic aortic valve disease in SAMP1 mice is associated with a decrease in serum klotho leading to inflammation, including macrophage infiltration and transforming growth factorbeta-1/scleraxis-driven myofibroblast differentiation in aortic valves. Restoration of serum Skl levels by adeno-associated virus 2 carrying mouse Skl cDNA effectively suppresses inflammation and myofibroblastic transition and attenuates aortic valve fibrosis. Skl may be a potential therapeutic target for fibrotic aortic valve disease. PMID- 29581214 TI - Effect of Lowering Diastolic Pressure in Patients With and Without Cardiovascular Disease: Analysis of the SPRINT (Systolic Blood Pressure Intervention Trial). AB - Systolic and diastolic blood pressure thresholds, below which cardiovascular events increase, are widely debated. Using data from the SPRINT (Systolic Blood Pressure Intervention Trial), we evaluated the relation between systolic and diastolic pressure and cardiovascular events among 1519 participants with or 7574 without prior cardiovascular disease. Using Cox regression, we examined the composite risk of myocardial infarction, other acute coronary syndrome, stroke, heart failure, or cardiovascular death, and follow-up systolic and diastolic pressure were analyzed as time-dependent covariates for a median of 3.1 years. Models were adjusted for age, sex, baseline systolic pressure, body mass index, 10-year Framingham risk score, and estimated glomerular filtration rate. A J shaped relationship with diastolic pressure was observed in both treatment arms in patients with or without cardiovascular disease (P nonlinearity<=0.002). When diastolic pressure fell <55 mm Hg, the hazards were at least 25% higher relative to 70 mm Hg (P=0.29). The hazard ratios (95% CI) of diastolic pressure <55 mm Hg versus 55 to 90 mm Hg were 1.68 (1.16-2.43), P value 0.006 and 1.52 (0.99-2.34), P value 0.06 in patients without and with prior cardiovascular disease, respectively. After adjusting for follow-up diastolic pressure, follow-up systolic pressure was not associated with the outcome in those without prior cardiovascular disease (P=0.64). In those with cardiovascular disease, adjusting for diastolic pressure, follow-up systolic pressure was associated with the risk in the intensive arm (hazard ratio per 10 mm Hg decrease, 0.86; 95% CI, 0.75 0.99; P interaction=0.02). Although the observed J-shaped relationship may be because of reverse causality in the SPRINT population, we advise caution in aggressively lowering diastolic pressure.

AB - Orb-weaving spiders use adhesive threads to delay the escape of insects from their webs until the spiders can locate and subdue the insects. These viscous threads are spun as paired flagelliform axial fibers coated by a cylinder of solution derived from the aggregate glands. As low molecular mass compounds (LMMCs) in the aggregate solution attract atmospheric moisture, the enlarging cylinder becomes unstable and divides into droplets. Within each droplet an adhesive glycoprotein core condenses. The plasticity and axial line extensibility of the glycoproteins are maintained by hygroscopic LMMCs. These compounds cause droplet volume to track changes in humidity and glycoprotein viscosity to vary approximately 1000-fold over the course of a day. Natural selection has tuned the performance of glycoprotein cores to the humidity of a species' foraging environment by altering the composition of its LMMCs. Thus, species from low humidity habits have more hygroscopic threads than those from humid forests. However, at their respective foraging humidities, these species' glycoproteins have remarkably similar viscosities, ensuring optimal droplet adhesion by balancing glycoprotein adhesion and cohesion. Optimal viscosity is also essential for integrating the adhesion force of multiple droplets. As force is transferred to a thread's support line, extending droplets draw it into a parabolic configuration, implementing a suspension bridge mechanism that sums the adhesive force generated over the thread span. Thus, viscous capture threads extend an orb spider's phenotype as a highly integrated complex of large proteins and small molecules that function as a self-assembling, highly tuned, environmentally responsive, adhesive biomaterial. Understanding the synergistic role of chemistry and design in spider adhesives, particularly the ability to stick in wet conditions, provides insight in designing synthetic adhesives for biomedical applications. PMID- 29581216 TI - The Receptor-Like Cytoplasmic Kinase STRK1 Phosphorylates and Activates CatC, Thereby Regulating H2O2 Homeostasis and Improving Salt Tolerance in Rice. AB - Salt stress can significantly affect plant growth and agricultural productivity. Receptor-like kinases (RLKs) are believed to play essential roles in plant growth, development, and responses to abiotic stresses. Here, we identify a receptor-like cytoplasmic kinase, salt tolerance receptor-like cytoplasmic kinase 1 (STRK1), from rice (Oryza sativa) that positively regulates salt and oxidative stress tolerance. Our results show that STRK1 anchors and interacts with CatC at the plasma membrane via palmitoylation. CatC is phosphorylated mainly at Tyr-210 and is activated by STRK1. The phosphorylation mimic form CatCY210D exhibits higher catalase activity both in vitro and in planta, and salt stress enhances STRK1-mediated tyrosine phosphorylation on CatC. Compared with wild-type plants, STRK1-overexpressing plants exhibited higher catalase activity and lower accumulation of H2O2 as well as higher tolerance to salt and oxidative stress. Our findings demonstrate that STRK1 improves salt and oxidative tolerance by phosphorylating and activating CatC and thereby regulating H2O2 homeostasis. Moreover, overexpression of STRK1 in rice not only improved growth at the seedling stage but also markedly limited the grain yield loss under salt stress conditions. Together, these results offer an opportunity to improve rice grain yield under salt stress. PMID- 29581219 TI - Prognostic Performance of Heart Rate Recovery on an Exercise Test in a Primary Prevention Population. AB - BACKGROUND: Heart rate (HR) recovery has been investigated in specific patient cohorts, but there is less information about the role of HR recovery in general populations. We investigated whether HR recovery has long-term prognostic significance in primary prevention. METHODS AND RESULTS: Exercise tests performed between 1993 and 2010 on patients aged 30 to 79 years without cardiovascular disease were included. Mortality was determined from Mayo Clinic records and Minnesota Death Index. Total, cardiovascular, and non-cardiovascular mortality was reported according to HR recovery <13 bpm using Cox regression. 19 551 patients were included, 6756 women (35%), age 51+/-10 years. There were 1271 deaths over follow-up of 12+/-5 years. HR recovery declined after age 60, and was also lower according to diabetes mellitus, hypertension, obesity, current smoking, and poor cardiorespiratory fitness but not sex or beta-blockers. Adjusting for these factors, abnormal HR recovery was a significant predictor of total (hazard ratio [95% confidence interval]=1.56 [1.384-1.77]), cardiovascular (1.95 [1.57-2.42]), and non-cardiovascular death (1.41 [1.22-1.64]). Hazard ratios for cardiovascular death according to abnormal HR recovery were significant in all age groups (30-59, 60-69, 70-79), in both sexes, in patients with and without hypertension, obesity, and diabetes mellitus, but not in patients taking beta-blockers, current smokers, and patients with normal cardiorespiratory fitness. CONCLUSIONS: HR recovery is a powerful prognostic factor predicting total, cardiovascular, and non-cardiovascular death in a primary prevention cohort. It performs consistently well according to sex, age, obesity, hypertension, and diabetes mellitus but shows diminished utility in patients taking beta-blockers, current smokers, and patients with normal cardiorespiratory fitness. PMID- 29581218 TI - RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study: Myocardial Dysfunction, Postoperative Neurocognitive Dysfunction, and 1 Year Follow-Up. AB - BACKGROUND: Remote ischemic preconditioning (RIPC) has been suggested to protect against certain forms of organ injury after cardiac surgery. Previously, we reported the main results of RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study, a multicenter trial randomizing 1403 cardiac surgery patients receiving either RIPC or sham-RIPC. METHODS AND RESULTS: In this follow-up paper, we present 1-year follow-up of the composite primary end point and its individual components (all-cause mortality, myocardial infarction, stroke and acute renal failure), in a sub-group of patients, intraoperative myocardial dysfunction assessed by transesophageal echocardiography and the incidence of postoperative neurocognitive dysfunction 5 to 7 days and 3 months after surgery. RIPC neither showed any beneficial effect on the 1-year composite primary end point (RIPC versus sham-RIPC 16.4% versus 16.9%) and its individual components (all-cause mortality [3.4% versus 2.5%], myocardial infarction [7.0% versus 9.4%], stroke [2.2% versus 3.1%], acute renal failure [7.0% versus 5.7%]) nor improved intraoperative myocardial dysfunction or incidence of postoperative neurocognitive dysfunction 5 to 7 days (67 [47.5%] versus 71 [53.8%] patients) and 3 months after surgery (17 [27.9%] versus 18 [27.7%] patients), respectively. CONCLUSIONS: Similar to our main study, RIPC had no effect on intraoperative myocardial dysfunction, neurocognitive function and long-term outcome in cardiac surgery patients undergoing propofol anesthesia.

PMID- 29581220 TI - Effect of Vegan Fecal Microbiota Transplantation on Carnitine- and Choline Derived Trimethylamine-N-Oxide Production and Vascular Inflammation in Patients With Metabolic Syndrome. AB - BACKGROUND: Intestinal microbiota have been found to be linked to cardiovascular disease via conversion of the dietary compounds choline and carnitine to the atherogenic metabolite TMAO (trimethylamine-N-oxide). Specifically, a vegan diet was associated with decreased plasma TMAO levels and nearly absent TMAO production on carnitine challenge. METHODS AND RESULTS: We performed a double blind randomized controlled pilot study in which 20 male metabolic syndrome patients were randomized to single lean vegan-donor or autologous fecal microbiota transplantation. At baseline and 2 weeks thereafter, we determined the ability to produce TMAO from d6-choline and d3-carnitine (eg, labeled and unlabeled TMAO in plasma and 24-hour urine after oral ingestion of 250 mg of both isotope-labeled precursor nutrients), and fecal samples were collected for analysis of microbiota composition. 18F-fluorodeoxyglucose positron emission tomography/computed tomography scans of the abdominal aorta, as well as ex vivo peripheral blood mononuclear cell cytokine production assays, were performed. At baseline, fecal microbiota composition differed significantly between vegans and metabolic syndrome patients. With vegan-donor fecal microbiota transplantation, intestinal microbiota composition in metabolic syndrome patients, as monitored by global fecal microbial community structure, changed toward a vegan profile in some of the patients; however, no functional effects from vegan-donor fecal microbiota transplantation were seen on TMAO production, abdominal aortic 18F fluorodeoxyglucose uptake, or ex vivo cytokine production from peripheral blood mononuclear cells. CONCLUSIONS: Single lean vegan-donor fecal microbiota transplantation in metabolic syndrome patients resulted in detectable changes in intestinal microbiota composition but failed to elicit changes in TMAO production capacity or parameters related to vascular inflammation.

PMID- 29581221 TI - Impact of Type 2 Myocardial Infarction (MI) on Hospital-Level MI Outcomes: Implications for Quality and Public Reporting. AB - BACKGROUND: The International Classification of Diseases (ICD) coding system does not recognize type 2 myocardial infarction (MI) as a separate entity; therefore, patients with type 2 MI continue to be categorized under the general umbrella of non-ST-segment-elevation myocardial infarction (NSTEMI). We aim to evaluate the impact of type 2 MI on hospital-level NSTEMI metrics and discuss the implications for quality and public reporting. METHODS AND RESULTS: We conducted a single center retrospective analysis of 1318 patients discharged with a diagnosis of NSTEMI between July 2013 and October 2014. The Third Universal Definition was used to define type 1 and type 2 MI. Weighted Kaplan-Meier curves were used to analyze risk of mortality and readmission. Overall, 1039 patients met NSTEMI criteria per the Third Universal Definition; of those, 264 (25.4%) had type 2 MI. Patients with type 2 MI were older, were more likely to have chronic kidney disease, and had lower peak troponin levels. Compared with type 1 MI patients, those with type 2 MI had higher inpatient mortality (17.4% versus 4.7%, P<0.0001) and were more likely to die from noncardiovascular causes (71.7% versus 25.0%, P<0.0001). Despite weighting for patient characteristics and discharge medications, patients with type 2 MI had higher mortality at both 30 days (risk ratio: 3.63; 95% confidence interval, 1.67-7.88) and 1 year (risk ratio: 1.98; 95% confidence interval, 1.44-2.73) after discharge. Type 2 MI was also associated with a lower 30-day cardiovascular-related readmission (risk ratio: 0.49; 95% confidence interval, 0.12-2.06). CONCLUSIONS: NSTEMI metrics are significantly affected by type 2 MI patients. Type 2 MI patients have distinct etiologies, are managed differently, and have higher mortality compared with patients with type 1 MI. Moving forward, it may be appropriate to exclude type 2 MI data from NSTEMI quality metrics. PMID- 29581222 TI - Device Therapies Among Patients Receiving Primary Prevention Implantable Cardioverter-Defibrillators in the Cardiovascular Research Network. AB - BACKGROUND: Primary prevention implantable cardioverter-defibrillators (ICDs) reduce mortality in selected patients with left ventricular systolic dysfunction by delivering therapies (antitachycardia pacing or shocks) to terminate potentially lethal arrhythmias; inappropriate therapies also occur. We assessed device therapies among adults receiving primary prevention ICDs in 7 healthcare systems. METHODS AND RESULTS: We linked medical record data, adjudicated device therapies, and the National Cardiovascular Data Registry ICD Registry. Survival analysis evaluated therapy probability and predictors after ICD implant from 2006 to 2009, with attention to Centers for Medicare and Medicaid Services Coverage With Evidence Development subgroups: left ventricular ejection fraction, 31% to 35%; nonischemic cardiomyopathy <9 months' duration; and New York Heart Association class IV heart failure with cardiac resynchronization therapy defibrillator. Among 2540 patients, 35% were <65 years old, 26% were women, and 59% were white. During 27 (median) months, 738 (29%) received >=1 therapy. Three year therapy risk was 36% (appropriate, 24%; inappropriate, 12%). Appropriate therapy was more common in men (adjusted hazard ratio [HR], 1.84; 95% confidence interval [CI], 1.43-2.35). Inappropriate therapy was more common in patients with atrial fibrillation (adjusted HR, 2.20; 95% CI, 1.68-2.87), but less common among patients >=65 years old versus younger (adjusted HR, 0.72; 95% CI, 0.54-0.95) and in recent implants (eg, in 2009 versus 2006; adjusted HR, 0.66; 95% CI, 0.46 0.95). In Centers for Medicare and Medicaid Services Coverage With Evidence Development analysis, inappropriate therapy was less common with cardiac resynchronization therapy defibrillator versus single chamber (adjusted HR, 0.55; 95% CI, 0.36-0.84); therapy risk did not otherwise differ for Centers for Medicare and Medicaid Services Coverage With Evidence Development subgroups. CONCLUSIONS: In this community cohort of primary prevention patients receiving ICD, therapy delivery varied across demographic and clinical characteristics, but did not differ meaningfully for Centers for Medicare and Medicaid Services Coverage With Evidence Development subgroups. PMID- 29581223 TI - Beneficial Pleiotropic Antidepressive Effects of Cardiovascular Disease Risk Factor Interventions in the Metabolic Syndrome. AB - BACKGROUND: Although the increased prevalence and severity of clinical depression and elevated cardiovascular disease risk represent 2 vexing public health issues, the growing awareness of their combined presentation compounds the challenge. The obese Zucker rat, a model of the metabolic syndrome, spontaneously develops significant depressive symptoms in parallel with the progression of the metabolic syndrome and, thus, represents a compelling model for study. The primary objective was to assess the impact on both cardiovascular outcomes, specifically vascular structure and function, and depressive symptoms in obese Zucker rats after aggressive treatment for cardiovascular disease risk factors with long-term exercise or targeted pharmacological interventions. METHODS AND RESULTS: We chronically treated obese Zucker rats with clinically relevant interventions against cardiovascular disease risk factors to determine impacts on vascular outcomes and depressive symptom severity. While most of the interventions (chronic exercise, anti-hypertensive, the interventions (long-term exercise, antihypertensive, antidyslipidemia, and antidiabetic) were differentially effective at improving vascular outcomes, only those that also resulted in a significant improvement to oxidant stress, inflammation, arachidonic acid metabolism (prostacyclin versus thromboxane A2), and their associated sequelae were effective at also blunting depressive symptom severity. Using multivariable analyses, discrimination between the effectiveness of treatment groups to maintain behavioral outcomes appeared to be dependent on breaking the cycle of inflammation and oxidant stress, with the associated outcomes of improving endothelial metabolism and both cerebral and peripheral vascular structure and function. CONCLUSIONS: This initial study provides a compelling framework from which to further interrogate the links between cardiovascular disease risk factors and depressive symptoms and suggests mechanistic links and potentially effective avenues for intervention. PMID- 29581224 TI - Vascular Cognitive Impairment Linked to Brain Endothelium Inflammation in Early Stages of Heart Failure in Mice. AB - BACKGROUND: Although advanced heart failure (HF) is a clinically documented risk factor for vascular cognitive impairment, the occurrence and pathomechanisms of vascular cognitive impairment in early stages of HF are equivocal. Here, we characterize vascular cognitive impairment in the early stages of HF development and assess whether cerebral hypoperfusion or prothrombotic conditions are involved. METHODS AND RESULTS: Tgalphaq*44 mice with slowly developing isolated HF triggered by cardiomyocyte-specific overexpression of G-alphaq*44 protein were studied before the end-stage HF, at the ages of 3, 6, and 10 months: before left ventricle dysfunction; at the stage of early left ventricle diastolic dysfunction (with preserved ejection fraction); and left ventricle diastolic/systolic dysfunction, respectively. In 6- to 10-month-old but not in 3-month-old Tgalphaq*44 mice, behavioral and cognitive impairment was identified with compromised blood-brain barrier permeability, most significantly in brain cortex, that was associated with myelin sheet loss and changes in astrocytes and microglia. Brain endothelial cells displayed increased E-selectin immunoreactivity, which was accompanied by increased amyloid-beta1-42 accumulation in piriform cortex and increased cortical oxidative stress (8-OHdG immunoreactivity). Resting cerebral blood flow measured by magnetic resonance imaging in vivo was preserved, but ex vivo NO-dependent cortical arteriole flow regulation was impaired. Platelet hyperreactivity was present in 3- to 10-month old Tgalphaq*44 mice, but it was not associated with increased platelet-dependent thrombogenicity. CONCLUSIONS: We report for the first time that vascular cognitive impairment is already present in the early stage of HF development, even before left ventricle systolic dysfunction. The underlying pathomechanism, independent of brain hypoperfusion, involves preceding platelet hyperreactivity and brain endothelium inflammatory activation. PMID- 29581225 TI - Prognostic Value of Serial N-Terminal Pro-B-Type Natriuretic Peptide Measurements in Adults With Congenital Heart Disease. AB - BACKGROUND: A single NT-proBNP (N-terminal pro-B-type natriuretic peptide) measurement is a strong prognostic factor in adult congenital heart disease. This study investigates NT-proBNP profiles within patients with adult congenital heart disease and relates these to cardiovascular events. METHODS AND RESULTS: In this prospective cohort, 602 patients with adult congenital heart disease were enrolled at the outpatient clinic (years 2011-2013). NT-proBNP was measured at study inclusion in 595 patients (median age 33 [IQR 25-41] years, 58% male, 90% NYHA I) and at subsequent annual visits. The primary end point was defined as death, heart failure, hospitalization, arrhythmia, thromboembolic event, or cardiac intervention; the secondary end point as death or heart failure. Repeated measurements were analyzed using linear mixed models and joint models. During a median follow-up of 4.4 [IQR 3.8-4.8] years, a total of 2424 repeated measurements were collected. Average NT-proBNP increase was 2.9 pmol/L the year before the primary end point (n=199, 34%) and 18.2 pmol/L before the secondary end point (n=58, 10%), compared with 0.3 pmol/L in patients who remained end point-free (P-value for difference in slope 0.006 and <0.001, respectively). In patients with elevated baseline NT-proBNP (>14 pmol/L, n=315, 53%), repeated measurements were associated with the primary end point (HR per 2-fold higher value 2.08; 95% CI 1.31-3.87; P<0.001) and secondary end point (HR 2.47; 95% CI 1.13-5.70; P=0.017), when adjusted for the baseline measurement. CONCLUSIONS: NT proBNP increased before the occurrence of events, especially in patients who died or developed heart failure. Serial NT-proBNP measurements could be of additional prognostic value in the annual follow-up of patients with adult congenitive heart disease with an elevated NT-proBNP. PMID- 29581226 TI - Cause-specific mortality in Swedish males diagnosed with non-psychotic mental disorders in late adolescence: a prospective population-based study. AB - BACKGROUND: While risk of premature death is most pronounced among persons with severe mental illness, also milder conditions are associated with increased all cause mortality. We examined non-psychotic mental (NPM) disorders and specific causes of natural death in a cohort of late adolescent men followed for up to 46 years. METHODS: Prospective cohort study of Swedish males (n=1 784 626) who took part in structured conscription interviews 1968-2005. 74 525 men were diagnosed with NPM disorders at or prior to conscription. Median follow-up time was 26 years. HRs for cause-specific mortality were calculated using Cox proportional hazards models. RESULTS: Risks in fully adjusted models were particularly elevated for death by infectious diseases (depressive and neurotic/adjustment disorders (HR 2.07; 95% CI 1.60 to 2.67), personality disorders (HR 2.90; 95% CI 1.96 to 4.28) and alcohol-related and other substance use disorders (HR 9.02; 95% CI 6.63 to 12.27)) as well as by gastrointestinal causes (depressive and neurotic/adjustment disorders (HR 1.64; 95% CI 1.42 to 1.89), personality disorders (HR 2.77; 95% CI 2.27 to 3.38) and alcohol-related/substance use disorders (HR 4.41; 95% CI 3.59 to 5.42)). CONCLUSION: Young men diagnosed with NPM disorders had a long-term increased mortality risk, in particular due to infectious and gastrointestinal conditions. These findings highlight the importance of early preventive actions for adolescents with mental illness. PMID- 29581227 TI - Clarity in research frameworks for studying 'health selective migration'. PMID- 29581228 TI - Socioeconomic inequalities in child vaccination in low/middle-income countries: what accounts for the differences? AB - BACKGROUND: Socioeconomic inequalities in child vaccination continue to be a global public health concern. This study aimed to measure and identify factors associated with socioeconomic inequalities in full immunisation coverage against the four core vaccine-preventable diseases (ie, bacille Calmette-Guerin, diphtheria-tetanus-pertussis (three doses), polio (three doses) and measles vaccines) in 46 low/middle-income countries. METHODS: The most recent nationally representative samples of children (aged 10-59 months, n=372 499) collected through the Demographic Health Surveys were used to measure vaccination rates. The concentration index (C) was used to quantify socioeconomic inequalities in vaccination coverage. Furthermore, meta-regression analyses were used to determine factors affecting socioeconomic inequalities in vaccination coverage across countries. RESULTS: Results suggested that immunisation coverage was pro rich in most countries (median C=0.161, IQR 0.131). Gambia (C=-0.146, 95% CI 0.223 to -0.069), Namibia (C=-0.093, 95% CI -0.145 to -0.041) and Kyrgyz Republic (C=-0.227, 95% CI -0.304 to -0.15) were the only countries where children who belong to higher socioeconomic status group were less likely to receive all the four core vaccines than their lower socioeconomic status counterparts. Meta regression analyses suggested that, across countries, the concentration of antenatal care visits among wealthier mothers was positively associated with the concentration of vaccination coverage among wealthier children (coefficient=0.606, 95% CI 0.301 to 0.911). CONCLUSIONS: Pro-rich distribution of child vaccination in most low/middle-income countries remains an important public health policy concern. Policies aimed to improve antenatal care visits among mothers in lower socioeconomic groups may mitigate socioeconomic inequalities in vaccination coverage in low/middle-income countries. PMID- 29581229 TI - Low level of knowledge of heart attack symptoms and inappropriate anticipated treatment-seeking behaviour among older Chinese: a cross-sectional survey. AB - BACKGROUND: Prehospital delay of acute myocardial infarction (AMI) is common globally, and Hong Kong-home of a rapidly ageing Chinese population-is not an exception. Seeking emergency medical care promptly is important for patients. Treatment-seeking behaviours have been shown to be associated with knowledge of AMI symptoms and specific cultural beliefs. This study aimed to assess the level of knowledge of AMI symptoms and expected treatment-seeking behaviour among older Chinese in Hong Kong. METHODS: A cross-sectional population-based survey was conducted at the Elderly Health Centres in Hong Kong from March to September 2016. Face-to-face interviews were conducted with a structured questionnaire based on previous studies and local adaptations. RESULTS: Among 1804 people aged 65 years and above who completed the questionnaire, chest pain (80.2%), palpitations (75.8%) and fainting (71.9%) were the major symptoms recognised as AMI related. Meanwhile, stomach ache (46.9%), coughing (45.4%) and neck pain (40.8%) were recognised as not AMI related. The mean expected discomfort intensity during AMI onset was 7.7 out of 10 (SD=2.1). Regarding the expected treatment-seeking behaviour, seeking non-emergent medical care was the most popular action when AMI symptoms emerged during the day, without chest pain or with lower discomfort intensity, whereas calling an ambulance was the most common option when AMI symptoms emerged at night or with high discomfort intensity. CONCLUSIONS: To minimise delays in seeking treatment, future health education should focus on increasing the public knowledge of AMI symptoms and the need to call an ambulance during an emergency. PMID- 29581230 TI - Association between circulating leptin levels and multiple sclerosis: a systematic review and meta-analysis. AB - AIM: Leptin, synthesised by adipocytes, has been identified as a hormone that can influence inflammatory activity. Several studies have investigated leptin levels in patients with multiple sclerosis (MS), but the results are not consistent. This study aims to derive a more precise evaluation on the relationship between circulating leptin levels and MS. DESIGN: A comprehensive literature searched up to July 2017 was conducted to evaluate the association of circulating leptin levels and MS. The random-effect model was applied to calculate pooled standardised mean difference (SMD) and its 95% CI. MAIN OUTCOME MEASURES: Circulating leptin levels of patients with MS and healthy controls. RESULTS: Of 2155 studies identified, 33 met eligibility criteria and 9 studies with 645 patients with MS and 586 controls were finally included in the meta-analysis. Meta-analysis revealed that, compared with the healthy control group, the MS group had significantly higher plasma/serum leptin levels, with the SMD of 0.70% and 95% CI (0.24 to 1.15). Subgroup analyses suggested that the leptin levels of patients with MS were associated with region, age, study sample size, measurement type, gender and blood sample type. CONCLUSION: Overall, our study suggests that patients with MS have a significantly higher leptin level than in healthy controls. Further mechanism studies and longitudinal large cohort studies are still needed to further reveal the role of leptin in the pathogenesis of MS.

AB - Cross-talk between different components of the intestinal barrier and the immune system may be important in maintaining gut homeostasis. A crucial part of the gut barrier is the mucus layer, a cross-linked gel on top of the intestinal epithelium that consists predominantly of the mucin glycoprotein MUC2. However, whether the mucin layer actively regulates intestinal immune cell responses is not clear. Because recent evidence suggests that intestinal dendritic cells (DCs) may be regulated by the mucus layer, we purified intestinal mucin, incubated it with human DCs, and determined the functional effects. Here we show that expression of the chemokine IL-8 and co-stimulatory DC markers CD86 and CD83 are significantly up-regulated on human DCs in the presence of intestinal mucins. Additionally, mucin-exposed DCs promoted neutrophil migration in an IL-8 dependent manner. The stimulatory effects of mucins on DCs were not due to mucin sample contaminants such as lipopolysaccharide, DNA, or contaminant proteins. Instead, mucin glycans are important for the pro-inflammatory effects on DCs. Thus, intestinal mucins are capable of inducing important pro-inflammatory functions in DCs, which could be important in driving inflammatory responses upon intestinal barrier damage. PMID- 29581232 TI - Distinct cargo-specific response landscapes underpin the complex and nuanced role of galectin-glycan interactions in clathrin-independent endocytosis. AB - Clathrin-independent endocytosis (CIE) is a form of endocytosis that lacks a defined cytoplasmic machinery. Here, we asked whether glycan interactions, acting from the outside, could be a part of that endocytic machinery. We show that the perturbation of global cellular patterns of protein glycosylation by modulation of metabolic flux affects CIE. Interestingly, these changes in glycosylation had cargo-specific effects. For example, in HeLa cells, GlcNAc treatment, which increases glycan branching, increased major histocompatibility complex class I (MHCI) internalization but inhibited CIE of the glycoprotein CD59 molecule (CD59). The effects of knocking down the expression of galectin 3, a carbohydrate binding protein and an important player in galectin-glycan interactions, were also cargo-specific and stimulated CD59 uptake. By contrast, inhibition of all galectin-glycan interactions by lactose inhibited CIE of both MHCI and CD59. None of these treatments affected clathrin-mediated endocytosis, implying that glycosylation changes specifically affect CIE. We also found that the galectin lattice tailors membrane fluidity and cell spreading. Furthermore, changes in membrane dynamics mediated by the galectin lattice affected macropinocytosis, an altered form of CIE, in HT1080 cells. Our results suggest that glycans play an important and nuanced role in CIE, with each cargo being affected uniquely by alterations in galectin and glycan profiles and their interactions. We conclude that galectin-driven effects exist on a continuum from stimulatory to inhibitory, with distinct CIE cargo proteins having unique response landscapes and with different cell types starting at different positions on these conceptual landscapes. PMID- 29581233 TI - Kinetics and structural features of dimeric glutamine-dependent bacterial NAD+ synthetases suggest evolutionary adaptation to available metabolites. AB - NADH (NAD+) and its reduced form NADH serve as cofactors for a variety of oxidoreductases that participate in many metabolic pathways. NAD+ also is used as substrate by ADP-ribosyl transferases and by sirtuins. NAD+ biosynthesis is one of the most fundamental biochemical pathways in nature, and the ubiquitous NAD+ synthetase (NadE) catalyzes the final step in this biosynthetic route. Two different classes of NadE have been described to date: dimeric single-domain ammonium-dependent NadENH3 and octameric glutamine-dependent NadEGln, and the presence of multiple NadE isoforms is relatively common in prokaryotes. Here, we identified a novel dimeric group of NadEGln in bacteria. Substrate preferences and structural analyses suggested that dimeric NadEGln enzymes may constitute evolutionary intermediates between dimeric NadENH3 and octameric NadEGln The characterization of additional NadE isoforms in the diazotrophic bacterium Azospirillum brasilense along with the determination of intracellular glutamine levels in response to an ammonium shock led us to propose a model in which these different NadE isoforms became active accordingly to the availability of nitrogen. These data may explain the selective pressures that support the coexistence of multiple isoforms of NadE in some prokaryotes. PMID- 29581234 TI - TRAF-interacting protein with forkhead-associated domain (TIFA) transduces DNA damage-induced activation of NF-kappaB. AB - DNA damage-induced NF-kappaB activation and the secretion of inflammatory cytokines play crucial roles in carcinogenesis and cellular senescence. However, the underlying mechanisms, especially the initial sensors and transducers connecting the nuclear DNA damage signal with cytoplasmic NF-kappaB activation remain incompletely understood. Here, we report that TRAF-interacting protein with forkhead-associated domain (TIFA), an established NF-kappaB activator in the cytosol, unexpectedly exhibited nuclear translocation and accumulation on damaged chromatin following genotoxic stress. Accordingly, we also found that DNA damage induced transcriptional activation and the resulting secretion of classic NF kappaB targets, including interleukin (IL)-6 and IL-8, was greatly enhanced in TIFA-overexpressing cells compared with control cells. Mechanistically, DNA damage-induced TIFA phosphorylation at threonine 9 (pThr-9), and this phosphorylation event, involving the pThr-binding forkhead-associated domain, was crucial for its enrichment on damaged chromatin and subsequent NF-kappaB activation. Moreover, in conjunction with its partner protein, the E3 ligase TNF receptor-associated factor 2 (TRAF2), TIFA relayed the DNA damage signals by stimulating ubiquitination of NF-kappaB essential modulator (NEMO), whose sumoylation, phosphorylation, and ubiquitination were critical for NF-kappaB's response to DNA damage. Consistently, TRAF2 knockdown suppressed TIFA overexpression-enhanced NEMO ubiquitination under genotoxic stress, and a unphosphorylatable Thr-9-mutated TIFA variant had only minor effects on NEMO poly ubiquitination. Finally, in agreement with the model of DNA damage-associated secretory senescence barrier against carcinogenesis, ectopic TIFA expression limited proliferation of multiple myeloma cancer cells. In conclusion our results indicate that TIFA functions as a key transducer in DNA damage-induced NF-kappaB activation. PMID- 29581235 TI - Myeloperoxidase-derived oxidants damage artery wall proteins in an animal model of chronic kidney disease-accelerated atherosclerosis. AB - Increased myeloperoxidase (MPO) levels and activity are associated with increased cardiovascular risk among individuals with chronic kidney disease (CKD). However, a lack of good animal models for examining the presence and catalytic activity of MPO in vascular lesions has impeded mechanistic studies into CKD-associated cardiovascular diseases. Here, we show for the first time that exaggerated atherosclerosis in a pathophysiologically relevant CKD mouse model is associated with increased macrophage-derived MPO activity. Male 7-week-old LDL receptor deficient mice underwent sham (control mice) or 5/6 nephrectomy and were fed either a low-fat or high-fat, high-cholesterol diet for 24 weeks, and the extents of atherosclerosis and vascular reactivity were assessed. MPO expression and oxidation products-protein-bound oxidized tyrosine moieties 3-chlorotyrosine, 3 nitrotyrosine, and o,o'-dityrosine-were examined with immunoassays and confirmed with mass spectrometry (MS). As anticipated, the CKD mice had significantly higher plasma creatinine, urea nitrogen, and intact parathyroid hormone along with lower hematocrit and body weight. On both the diet regimens, CKD mice did not have hypertension but had lower cholesterol and triglyceride levels than the control mice. Despite the lower cholesterol levels, CKD mice had increased aortic plaque areas, fibrosis, and luminal narrowing. They also exhibited increased MPO expression and activity (i.e. increased oxidized tyrosines) that co-localized with infiltrating lesional macrophages and diminished vascular reactivity. In summary, unlike non-CKD mouse models of atherosclerosis, CKD mice exhibit increased MPO expression and catalytic activity in atherosclerotic lesions, which co-localize with lesional macrophages. These results implicate macrophage-derived MPO in CKD-accelerated atherosclerosis. PMID- 29581236 TI - Cryo-EM structure of Escherichia coli sigma70 RNA polymerase and promoter DNA complex revealed a role of sigma non-conserved region during the open complex formation. AB - First step of gene expression is transcribing the genetic information stored in DNA to RNA by the transcription machinery including RNA polymerase (RNAP). In Escherichia coli, a primary sigma70 factor forms the RNAP holoenzyme to express housekeeping genes. The sigma70 contains a large insertion between the conserved regions 1.2 and 2.1, the sigma non-conserved region (sigmaNCR), but its function remains to be elucidated. In this study, we determined the cryo-EM structures of the E. coli RNAP sigma70 holoenzyme and its complex with promoter DNA (open complex, RPo) at 4.2 and 5.75 A resolutions, respectively, to reveal native conformations of RNAP and DNA. The RPo structure presented here found an interaction between the sigmaNCR and promoter DNA just upstream of the -10 element, which was not observed in a previously determined E. coli RNAP transcription initiation complex (RPo plus short RNA) structure by X-ray crystallography because of restraint of crystal packing effects. Disruption of the sigmaNCR and DNA interaction by the amino acid substitutions (R157A/R157E) influences the DNA opening around the transcription start site and therefore decreases the transcription activity of RNAP. We propose that the sigmaNCR and DNA interaction is conserved in proteobacteria, and RNAP in other bacteria replaces its role with a transcription factor. PMID- 29581237 TI - Female fertility preservation: past, present and future. AB - Anti-cancer therapy, particularly chemotherapy, damages ovarian follicles and promotes ovarian failure. The only pharmacological means for protecting the ovaries from chemotherapy-induced injury is gonadotrophin-releasing hormone agonist, but its efficiency remains controversial; ovarian transposition is used to shield the ovary from radiation when indicated. Until the late 1990s, the only option for fertility preservation and restoration in women with cancer was embryo cryopreservation. The development of other assisted reproductive technologies such as mature oocyte cryopreservation and in vitro maturation of oocytes has contributed to fertility preservation. Treatment regimens to obtain mature oocytes/embryos have been modified to overcome various limitations of conventional ovarian stimulation protocols. In the last decades, several centres have begun cryopreserving ovarian samples containing primordial follicles from young patients before anti-cancer therapy. The first live birth following implantation of cryopreserved-thawed ovarian tissue was reported in 2004; since then, the number has risen to more than 130. Nowadays, ovarian tissue cryopreservation can be combined with in vitro maturation and vitrification of oocytes. The use of cryopreserved oocytes eliminates the risk posed by ovarian implantation of reseeding the cancer. Novel methods for enhancing follicular survival after implantation are presently being studied. In addition, researchers are currently investigating agents for ovarian protection. It is expected that the risk of reimplantation of malignant cells with ovarian grafts will be overcome with the putative development of an artificial ovary and an efficient follicle class- and species-dependent in vitro system for culturing primordial follicles. PMID- 29581238 TI - Role of dysfunctional adipocytes in cholesterol-induced nonobese metabolic syndrome. AB - Many studies have reported the causes of obese metabolic syndrome (MS); however, the causes of nonobese MS (NMS) remain unknown. In this study, we demonstrated that inflamed dysfunctional adipose tissue plays a crucial role in cholesterol induced NMS. Control (C), high cholesterol (HC) and HC with 10% fructose in drinking water (HCF) diets were fed to Sprague-Dawley rats for 12 weeks. After 12 weeks, the body weights of the C- and HC-fed rats were comparable, but the weights of the HCF-fed rats were relatively low. Cholesterol caused metabolic problems such as high blood pressure, hypercholesterolemia and hypoinsulinemia. The HCF-fed rats exhibited whole-body insulin resistance with low circulating high-density lipoprotein levels. Increases in the tumor necrosis factor alpha level in the plasma, the number of CD68+ macrophages and the free nuclear factor kappaB level in gonadal white adipose tissue (gWAT) resulted in local inflammation, which appeared as inflamed dysfunctional gWAT. Reduced superoxide dismutases (SODs) deteriorate natural antioxidant defense systems and induce reactive oxygen species in gWAT. Dysregulation of plasma levels of catecholamine, adipokines (leptin and adiponectin), hormone-sensitive lipase and perilipin in cholesterol-induced inflamed adipose tissue contributed to increased lipolysis and increased circulating nonesterified fatty acids. Cholesterol activated inflammation, lipolysis and cell death in 3T3-L1 adipocytes. Moreover, Chol-3T3 CM reduced the population of M2-type Raw264.7 macrophages, indicating that the macrophage polarization is mediated by cholesterol. Together, our findings indicate that inflamed dysfunctional adipocytes are critical in NMS, supporting the development of anti-inflammatory agents as potential therapeutic drugs for treating NMS. PMID- 29581240 TI - Intracranial Arterial Dolichoectasia and Stenosis: Risk Factors and Relation to Cerebral Small Vessel Disease. AB - BACKGROUND AND PURPOSE: Intracranial arterial dolichoectasia (IADE) is a poorly understood arteriopathy compared with intracranial atherosclerotic stenosis (ICAS). We aimed to investigate the risk factors of IADE and ICAS and their relationship with neuroimaging markers of cerebral small vessel disease in a population-based study. METHODS: This study comprised 1237 participants (aged 57.2+/-9.4 years, 37.6% men) who underwent brain magnetic resonance imaging and magnetic resonance angiography. IADE was assessed based on basilar artery dolichoectasia (diameter, height of bifurcation, and laterality of basilar artery) and dilation of basilar artery and internal carotid artery (intracranial volume-adjusted diameter >=2 SD). ICAS was defined as any degree of stenosis in at least 1 intracranial artery. The neuroimaging markers of cerebral small vessel disease, including lacunes, white matter hyperintensities, microbleeds, dilated perivascular spaces, and brain atrophy, were evaluated. RESULTS: Basilar arterial dolichoectasia was observed in 3.6% (45/1237); intracranial arterial dilation in 5.9% (67/1142); and ICAS in 15.7% (194/1237). Older age, higher systolic blood pressure, diabetes mellitus, higher LDL-C (low-density lipoprotein cholesterol) and lower HDL-C (high-density lipoprotein cholesterol) were associated with the presence of ICAS (all P<0.001), whereas only older age was associated with IADE. ICAS was associated with lacunes (odds ratio, 2.91; 95% confidence interval, 1.96 4.34; P<0.001), increased white matter hyperintensities volume (beta+/-SE, 0.54+/ 0.13; P<0.001), and brain atrophy (beta+/-SE, -1.16+/-0.21; P<0.001), whereas basilar arterial dolichoectasia was mainly associated with dilated perivascular spaces in basal ganglia (odds ratio, 2.20; 95% confidence interval, 1.20-4.02; P=0.01) and, to a lesser extent, associated with lacunes and microbleeds. CONCLUSIONS: IADE and ICAS had different risk factor profiles and associated with different imaging phenotypes of cerebral small vessel disease, suggesting different underlying mechanisms.

AB - Insulin-like growth factor 1(IGF1) and ephrin ligand (EFN)-receptor (EPH) signaling are both crucial for bone cell function and skeletal development and maintenance. IGF1 signaling is the major mediator of growth hormone-induced bone growth, but a host of different signals and factors regulate IGF1 signaling at the systemic and local levels. Disruption of the Igf1 gene results in reduced peak bone mass in both experimental animal models and humans. Additionally, EFN EPH signaling is a complex system which, particularly through cell-cell interactions, contributes to the development and differentiation of many bone cell types. Recent evidence has demonstrated several ways in which the IGF1 and EFN-EPH signaling pathways interact with and depend upon each other to regulate bone cell function. While much remains to be elucidated, the interaction between these two signaling pathways opens a vast array of new opportunities for investigation into the mechanisms of and potential therapies for skeletal conditions such as osteoporosis and fracture repair.

AB - Several studies have reported an association between levels of folate, homocysteine, and vitamin B12 and the risk of colorectal polyps. Here, our aim is to examine the possible effect of folate, homocysteine, and vitamin B12 levels on the risk of colorectal polyps by means of meta-analysis based quantitative synthesis. According to our inclusion/exclusion criteria, a total of 13 case control studies were enrolled. The P-value of the association test, standard mean difference (SMD), and 95% confidence interval (CI) were calculated. Pooled analysis data showed a negative correlation between the risk of colorectal polyps and the levels of serum folate, red blood cell (RBC) folate, or vitamin B12 (all P>0.05). Nevertheless, for homocysteine level, we also observed a statistically significant difference between cases and controls in the overall and subgroup analysis of hospital-based control (HB), population-based control (PB), Chinese, Caucasian, or Asian (all P<0.05, SMD > 0). We found that increased levels of homocysteine may be statistically and significantly related to the risk of colorectal polyps. PMID- 29581247 TI - Association of single nucleotide polymorphisms in CACNA 1A/CACNA 1C/CACNA 1H calcium channel genes with diabetic peripheral neuropathy in Chinese population. AB - The present study was conducted to explore the correlations between single nucleotide polymorphisms (SNPs) in the calcium channel CACNA 1A, CACNA 1C, and CACNA 1H genes and diabetic peripheral neuropathy (DPN) amongst the Chinese population. In total, 281 patients diagnosed with type 2 diabetes participated in the present study. These patients were divided into the case group, which was subdivided into the DPN (143 cases) and the non-DPN groups (138 cases). Subsequently, 180 healthy individuals that had undergone routine health examinations were also recruited and assigned to the control group. PCR restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotype and allele frequencies of CACNA 1A, CACNA 1C, and CACNA 1H genes; logistic regression analysis to investigate the association of gene polymorphisms with DNP. Gene-gene interactions were then detected by generalized multifactor dimensionality reduction (GMDR). The results revealed that CACNA 1A rs2248069 and rsl6030, CACNA 1C rs216008 and rs2239050, and CACNA 1H rs3794619, and rs7191246 SNPs were all associated with DPN, while rs2248069, rsl6030, rs2239050, and rs7191246 polymorphisms were attributed to the susceptibility to DPN. It was also observed that the optimal models were three-, four- and five-dimensional models with a prediction accuracy of 61.05% and the greatest consistency of cross validation was 10/10. In summary, these findings demonstrated that the SNPs in the CACNA 1A, CACNA 1C, and CACNA 1H genes were involved in the pathophysiology of DPN. In addition, polymorphisms in the CACNA 1A, CACNA 1C, and CACNA 1H genes and their interactions also had effects on DPN. PMID- 29581246 TI - The association of neutrophil to lymphocyte ratio, mean platelet volume, and platelet distribution width with diabetic retinopathy and nephropathy: a meta analysis. AB - The aim of the present study was to investigate the correlation of neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV), and platelet distribution width (PDW) with diabetic nephropathy (DN) and diabetic retinopathy (DR). We searched for eligible studies from PubMed, Embase, Web of Science, and CNKI up to 1 December 2017. Standardized mean difference (SMD) was calculated with a confidence interval (CI) of 95%. A total of 48 studies were included in our meta analysis. Compared with patients with type II diabetes mellitus (T2DM) and without DR, NLR, MPV, and PDW were higher in patients with DR (SMD = 0.77; 95% CI: 0.49-1.05; P<0.001; SMD = 0.68; 95% CI: 0.36-0.99; P<0.001; SMD = 0.52; 95% CI: 0.28-0.76; P<0.01). Compared with patients with T2DM and without DN, NLR, MPV, and PDW were higher in patients with DN (SMD = 0.63; 95% CI: 0.43-0.83; P<0.001; SMD = 0.81; 95% CI: 0.36-1.25; P<0.001; SMD = 0.70; 95% CI: 0.50-0.90; P<0.001). We also found that MPV was strongly associated with the severity of DR, and NLR was closely related to the degree of DN. Our findings indicated that NLR, MPV, and PDW could be recommended as inexpensive diagnostic biomarkers for DN and DR. However, considering several limitations in the present study, further high quality clinical studies should be performed to investigate the relationship of NLR, MPV, and PDW to DN and DR.

AB - Jeanloz & Kavner have a very timely contribution which raises some very important issues concerning the measurement of temperature using spectroradiometry. In this discussion of the paper, we intend to show that while all the issues raised by the authors should be of real concern to all workers, some of the issues have indeed been resolved with improved technique. However, we agree with the authorn that there are several issues that must be resolved and caution is necessary in interpreting the observations. PMID- 29581249 TI - Hypoxia-inducible factor prolyl hydroxylase inhibitor roxadustat (FG-4592) protects against cisplatin-induced acute kidney injury. AB - Renal hypoxia occurs in acute kidney injury (AKI) of various etiologies. Activation of hypoxia-inducible transcription factor (HIF) has been identified as an important mechanism of cellular adaptation to low oxygen. Preconditional HIF activation protects against AKI, suggesting a new approach in AKI treatment. HIF is degraded under normoxic conditions mediated by oxygen-dependent hydroxylation of specific prolyl residues of the regulative alpha-subunits by HIF prolyl hydroxylases (PHD). FG-4592 is a novel, orally active, small-molecule HIF PHD inhibitor for the treatment of anemia in patients with chronic kidney disease (CKD). The current study aimed to evaluate the effect of FG-4592 (Roxadustat) on cis-diamminedichloroplatinum (cisplatin)-induced kidney injury. In mice, pretreatment with FG-4592 markedly ameliorated cisplatin-induced kidney injury as shown by the improved renal function (blood urea nitrogen (BUN), serum creatinine (Scr), and cystatin C) and kidney morphology (periodic acid-Schiff (PAS) staining) in line with a robust blockade of renal tubular injury markers of kidney injury molecule 1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL). Meanwhile, the renal apoptosis and inflammation induced by cisplatin were also strikingly attenuated in FG-4592-treated mice. Along with the protective effects shown above, FG-4592 pretreatment strongly enhanced HIF-1alpha in tubular cells, as well as the expressions of HIF target genes. FG-4592 alone did not affect the renal function and morphology in mice. In vitro, FG-4592 treatment significantly up-regulated HIF-1alpha and protected the tubular cells against cisplatin-induced apoptosis. In summary, FG-4592 treatment remarkably ameliorated the cisplatin-induced kidney injury possibly through the stabilization of HIF. Thus, besides the role in treating CKD anemia, the clinical use of FG-4592 also could be extended to AKI. PMID- 29581251 TI - The opportunity cost of animal based diets exceeds all food losses. AB - Food loss is widely recognized as undermining food security and environmental sustainability. However, consumption of resource-intensive food items instead of more efficient, equally nutritious alternatives can also be considered as an effective food loss. Here we define and quantify these opportunity food losses as the food loss associated with consuming resource-intensive animal-based items instead of plant-based alternatives which are nutritionally comparable, e.g., in terms of protein content. We consider replacements that minimize cropland use for each of the main US animal-based food categories. We find that although the characteristic conventional retail-to-consumer food losses are ~30% for plant and animal products, the opportunity food losses of beef, pork, dairy, poultry, and eggs are 96%, 90%, 75%, 50%, and 40%, respectively. This arises because plant based replacement diets can produce 20-fold and twofold more nutritionally similar food per cropland than beef and eggs, the most and least resource intensive animal categories, respectively. Although conventional and opportunity food losses are both targets for improvement, the high opportunity food losses highlight the large potential savings beyond conventionally defined food losses. Concurrently replacing all animal-based items in the US diet with plant-based alternatives will add enough food to feed, in full, 350 million additional people, well above the expected benefits of eliminating all supply chain food waste. These results highlight the importance of dietary shifts to improving food availability and security. PMID- 29581250 TI - LSD1 activates a lethal prostate cancer gene network independently of its demethylase function. AB - Medical castration that interferes with androgen receptor (AR) function is the principal treatment for advanced prostate cancer. However, clinical progression is universal, and tumors with AR-independent resistance mechanisms appear to be increasing in frequency. Consequently, there is an urgent need to develop new treatments targeting molecular pathways enriched in lethal prostate cancer. Lysine-specific demethylase 1 (LSD1) is a histone demethylase and an important regulator of gene expression. Here, we show that LSD1 promotes the survival of prostate cancer cells, including those that are castration-resistant, independently of its demethylase function and of the AR. Importantly, this effect is explained in part by activation of a lethal prostate cancer gene network in collaboration with LSD1's binding protein, ZNF217. Finally, that a small-molecule LSD1 inhibitor-SP-2509-blocks important demethylase-independent functions and suppresses castration-resistant prostate cancer cell viability demonstrates the potential of LSD1 inhibition in this disease. PMID- 29581252 TI - Global increase and geographic convergence in antibiotic consumption between 2000 and 2015. AB - Tracking antibiotic consumption patterns over time and across countries could inform policies to optimize antibiotic prescribing and minimize antibiotic resistance, such as setting and enforcing per capita consumption targets or aiding investments in alternatives to antibiotics. In this study, we analyzed the trends and drivers of antibiotic consumption from 2000 to 2015 in 76 countries and projected total global antibiotic consumption through 2030. Between 2000 and 2015, antibiotic consumption, expressed in defined daily doses (DDD), increased 65% (21.1-34.8 billion DDDs), and the antibiotic consumption rate increased 39% (11.3-15.7 DDDs per 1,000 inhabitants per day). The increase was driven by low- and middle-income countries (LMICs), where rising consumption was correlated with gross domestic product per capita (GDPPC) growth (P = 0.004). In high-income countries (HICs), although overall consumption increased modestly, DDDs per 1,000 inhabitants per day fell 4%, and there was no correlation with GDPPC. Of particular concern was the rapid increase in the use of last-resort compounds, both in HICs and LMICs, such as glycylcyclines, oxazolidinones, carbapenems, and polymyxins. Projections of global antibiotic consumption in 2030, assuming no policy changes, were up to 200% higher than the 42 billion DDDs estimated in 2015. Although antibiotic consumption rates in most LMICs remain lower than in HICs despite higher bacterial disease burden, consumption in LMICs is rapidly converging to rates similar to HICs. Reducing global consumption is critical for reducing the threat of antibiotic resistance, but reduction efforts must balance access limitations in LMICs and take account of local and global resistance patterns. PMID- 29581253 TI - NAA80 is actin's N-terminal acetyltransferase and regulates cytoskeleton assembly and cell motility. AB - Actin, one of the most abundant proteins in nature, participates in countless cellular functions ranging from organelle trafficking and pathogen motility to cell migration and regulation of gene transcription. Actin's cellular activities depend on the dynamic transition between its monomeric and filamentous forms, a process exquisitely regulated in cells by a large number of actin-binding and signaling proteins. Additionally, several posttranslational modifications control the cellular functions of actin, including most notably N-terminal (Nt) acetylation, a prevalent modification throughout the animal kingdom. However, the biological role and mechanism of actin Nt-acetylation are poorly understood, and the identity of actin's N-terminal acetyltransferase (NAT) has remained a mystery. Here, we reveal that NAA80, a suggested NAT enzyme whose substrate specificity had not been characterized, is Nt-acetylating actin. We further show that actin Nt-acetylation plays crucial roles in cytoskeletal assembly in vitro and in cells. The absence of Nt-acetylation leads to significant differences in the rates of actin filament depolymerization and elongation, including elongation driven by formins, whereas filament nucleation by the Arp2/3 complex is mostly unaffected. NAA80-knockout cells display severely altered cytoskeletal organization, including an increase in the ratio of filamentous to globular actin, increased filopodia and lamellipodia formation, and accelerated cell motility. Together, the results demonstrate NAA80's role as actin's NAT and reveal a crucial role for actin Nt-acetylation in the control of cytoskeleton structure and dynamics.

The chemotaxis system of Escherichia coli provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level. These bacteria sense chemical gradients with transmembrane proteins [methyl-accepting chemotaxis proteins (MCPs)] that have an extracellular ligand binding domain and intracellular histidine kinases, adenylate cyclases, methyl accepting proteins, and phosphatases (HAMP) and signaling domains that govern locomotor behavior. HAMP domains are versatile input-output elements that operate in a variety of bacterial signaling proteins, including the sensor kinases of two component regulatory systems. The MCP HAMP domain receives stimulus information and in turn modulates output signaling activity. This study describes mutants of the Escherichia coli serine chemoreceptor, Tsr, that identify a heptad-repeat structural motif (LLF) at the membrane-proximal end of the receptor signaling domain that is critical for HAMP output control. The homodimeric Tsr signaling domain is an extended, antiparallel, four-helix bundle that controls the activity of an associated kinase. The N terminus of each subunit adjoins the HAMP domain; the LLF residues lie at the C terminus of the methylation-helix bundle. We found, by using in vivo Forster resonance energy transfer kinase assays, that most amino acid replacements at any of the LLF residues abrogate chemotactic responses to serine and lock Tsr output in a kinase-active state, impervious to HAMP-mediated down-regulation. We present evidence that the LLF residues may function like a leucine zipper to promote stable association of the C-terminal signaling helices, thereby creating a metastable helix-packing platform for the N-terminal signaling helices that facilitates conformational control by the HAMP domains in MCP-family chemoreceptors. PMID- 29581255 TI - Anti-CTLA-4 therapy requires an Fc domain for efficacy. AB - Ipilimumab, a monoclonal antibody that recognizes cytotoxic T lymphocyte antigen (CTLA)-4, was the first approved "checkpoint"-blocking anticancer therapy. In mouse tumor models, the response to antibodies against CTLA-4 depends entirely on expression of the Fcgamma receptor (FcgammaR), which may facilitate antibody dependent cellular phagocytosis, but the contribution of simple CTLA-4 blockade remains unknown. To understand the role of CTLA-4 blockade in the complete absence of Fc-dependent functions, we developed H11, a high-affinity alpaca heavy chain-only antibody fragment (VHH) against CTLA-4. The VHH H11 lacks an Fc portion, binds monovalently to CTLA-4, and inhibits interactions between CTLA-4 and its ligand by occluding the ligand-binding motif on CTLA-4 as shown crystallographically. We used H11 to visualize CTLA-4 expression in vivo using whole-animal immuno-PET, finding that surface-accessible CTLA-4 is largely confined to the tumor microenvironment. Despite this, H11-mediated CTLA-4 blockade has minimal effects on antitumor responses. Installation of the murine IgG2a constant region on H11 dramatically enhances its antitumor response. Coadministration of the monovalent H11 VHH blocks the efficacy of a full-sized therapeutic antibody. We were thus able to demonstrate that CTLA-4-binding antibodies require an Fc domain for antitumor effect. PMID- 29581257 TI - Reversal of orbital angular momentum arising from an extreme Doppler shift. AB - The linear Doppler shift is familiar as the rise and fall in pitch of a siren as it passes by. Less well known is the rotational Doppler shift, proportional to the rotation rate between source and receiver, multiplied by the angular momentum carried by the beam. In extreme cases the Doppler shift can be larger than the rest-frame frequency and for a red shift, the observed frequency then becomes "negative." In the linear case, this effect is associated with the time reversal of the received signal, but it can be observed only with supersonic relative motion between the source and receiver. However, the rotational case is different; if the radius of rotation is smaller than the wavelength, then the velocities required to observe negative frequencies are subsonic. Using an acoustic source at [Formula: see text]100 Hz we create a rotational Doppler shift larger than the laboratory-frame frequency. We observe that once the red-shifted wave passes into the "negative frequency" regime, the angular momentum associated with the sound is reversed in sign compared with that of the laboratory frame. These low-velocity laboratory realizations of extreme Doppler shifts have relevance to superoscillatory fields and offer unique opportunities to probe interactions with rotating bodies and aspects of pseudorelativistic frame translation. PMID- 29581256 TI - PUMA amplifies necroptosis signaling by activating cytosolic DNA sensors. AB - Necroptosis, a form of regulated necrotic cell death, is governed by RIP1/RIP3 mediated activation of MLKL. However, the signaling process leading to necroptotic death remains to be elucidated. In this study, we found that PUMA, a proapoptotic BH3-only Bcl-2 family member, is transcriptionally activated in an RIP3/MLKL-dependent manner following induction of necroptosis. The induction of PUMA, which is mediated by autocrine TNF-alpha and enhanced NF-kappaB activity, contributes to necroptotic death in RIP3-expressing cells with caspases inhibited. On induction, PUMA promotes the cytosolic release of mitochondrial DNA and activation of the DNA sensors DAI/Zbp1 and STING, leading to enhanced RIP3 and MLKL phosphorylation in a positive feedback loop. Furthermore, deletion of PUMA partially rescues necroptosis-mediated developmental defects in FADD deficient embryos. Collectively, our results reveal a signal amplification mechanism mediated by PUMA and cytosolic DNA sensors that is involved in TNF driven necroptotic death in vitro and in vivo. PMID- 29581258 TI - CSI1, PATROL1, and exocyst complex cooperate in delivery of cellulose synthase complexes to the plasma membrane. AB - Cellulose synthesis occurs exclusively at the plasma membrane by cellulose synthase complexes (CSCs). Therefore, delivery of CSCs to discrete sites at the plasma membrane is critical for cellulose synthesis. Despite their significance, the delivery of CSCs is poorly understood. Here we used proteomics approaches, functional genetics, and live cell imaging to show that the de novo secretion of CSCs is mediated by cooperation among cellulose synthase interactive 1 (CSI1), the plant-specific protein PATROL1, and exocyst complex in Arabidopsis thaliana We propose that CSI1 plays a role in marking the docking site, which allows CSCs containing vesicles access to the plasma membrane through its interaction with microtubules. PATROL1 assists in exocytosis by its interaction with multiple components, including CSI1, CSCs, and exocyst subunits. Both PATROL1 and the exocyst complex determine the rate of delivery of CSCs to the plasma membrane. By monitoring the exocyst complex, PATROL1, CSI1, and CSCs dynamics in real time, we present a timeline of events for exocytosis of CSCs. Our findings provide unique insights into the evolution of exocytosis in eukaryotes. PMID- 29581259 TI - LTP requires postsynaptic PDZ-domain interactions with glutamate receptor/auxiliary protein complexes. AB - Long-term potentiation (LTP) is a persistent strengthening of synaptic transmission in the brain and is arguably the most compelling cellular and molecular model for learning and memory. Previous work found that both AMPA receptors and exogenously expressed kainate receptors are equally capable of expressing LTP, despite their limited homology and their association with distinct auxiliary subunits, indicating that LTP is far more promiscuous than previously thought. What might these two subtypes of glutamate receptor have in common? Using a single-cell molecular replacement strategy, we demonstrate that the AMPA receptor auxiliary subunit TARP gamma-8, via its PDZ-binding motif, is indispensable for both basal synaptic transmission and LTP. Remarkably, kainate receptors and their auxiliary subunits Neto proteins share the same requirement of PDZ-binding domains for synaptic trafficking and LTP. Together, these results suggest that a minimal postsynaptic requirement for LTP is the PDZ binding of glutamate receptors/auxiliary subunits to PSD scaffolding proteins. PMID- 29581260 TI - Molecular and structural architecture of polyQ aggregates in yeast. AB - Huntington's disease is caused by the expansion of a polyglutamine (polyQ) tract in the N-terminal exon of huntingtin (HttEx1), but the cellular mechanisms leading to neurodegeneration remain poorly understood. Here we present in situ structural studies by cryo-electron tomography of an established yeast model system of polyQ toxicity. We find that expression of polyQ-expanded HttEx1 results in the formation of unstructured inclusion bodies and in some cases fibrillar aggregates. This contrasts with recent findings in mammalian cells, where polyQ inclusions were exclusively fibrillar. In yeast, polyQ toxicity correlates with alterations in mitochondrial and lipid droplet morphology, which do not arise from physical interactions with inclusions or fibrils. Quantitative proteomic analysis shows that polyQ aggregates sequester numerous cellular proteins and cause a major change in proteome composition, most significantly in proteins related to energy metabolism. Thus, our data point to a multifaceted toxic gain-of-function of polyQ aggregates, driven by sequestration of endogenous proteins and mitochondrial and lipid droplet dysfunction. PMID- 29581261 TI - Mechanistic insights into staphylopine-mediated metal acquisition. AB - Metal acquisition is vital to pathogens for successful infection within hosts. Staphylopine (StP), a broad-spectrum metallophore biosynthesized by the major human pathogen, Staphylococcus aureus, plays a central role in transition-metal acquisition and bacterial virulence. The StP-like biosynthesis loci are present in various pathogens, and the proteins responsible for StP/metal transportation have been determined. However, the molecular mechanisms of how StP/metal complexes are recognized and transported remain unknown. We report multiple structures of the extracytoplasmic solute-binding protein CntA from the StP/metal transportation system in apo form and in complex with StP and three different metals. We elucidated a sophisticated metal-bound StP recognition mechanism and determined that StP/metal binding triggers a notable interdomain conformational change in CntA. Furthermore, CRISPR/Cas9-mediated single-base substitution mutations and biochemical analysis highlight the importance of StP/metal recognition for StP/metal acquisition. These discoveries provide critical insights into the study of novel metal-acquisition mechanisms in microbes. PMID- 29581262 TI - Continuous plating/stripping behavior of solid-state lithium metal anode in a 3D ion-conductive framework. AB - The increasing demands for efficient and clean energy-storage systems have spurred the development of Li metal batteries, which possess attractively high energy densities. For practical application of Li metal batteries, it is vital to resolve the intrinsic problems of Li metal anodes, i.e., the formation of Li dendrites, interfacial instability, and huge volume changes during cycling. Utilization of solid-state electrolytes for Li metal anodes is a promising approach to address those issues. In this study, we use a 3D garnet-type ion conductive framework as a host for the Li metal anode and study the plating and stripping behaviors of the Li metal anode within the solid ion-conductive host. We show that with a solid-state ion-conductive framework and a planar current collector at the bottom, Li is plated from the bottom and rises during deposition, away from the separator layer and free from electrolyte penetration and short circuit. Owing to the solid-state deposition property, Li grows smoothly in the pores of the garnet host without forming Li dendrites. The dendrite-free deposition and continuous rise/fall of Li metal during plating/stripping in the 3D ion-conductive host promise a safe and durable Li metal anode. The solid-state Li anode shows stable cycling at 0.5 mA cm-2 for 300 h with a small overpotential, showing a significant improvement compared with reported Li anodes with ceramic electrolytes. By fundamentally eliminating the dendrite issue, the solid Li metal anode shows a great potential to build safe and reliable Li metal batteries.

PMID- 29581263 TI - Binding site for coenzyme A revealed in the structure of pyruvate:ferredoxin oxidoreductase from Moorella thermoacetica. AB - Pyruvate:ferredoxin oxidoreductase (PFOR) is a microbial enzyme that uses thiamine pyrophosphate (TPP), three [4Fe-4S] clusters, and coenzyme A (CoA) in the reversible oxidation of pyruvate to generate acetyl-CoA and carbon dioxide. The two electrons that are generated as a result of pyruvate decarboxylation are used in the reduction of low potential ferredoxins, which provide reducing equivalents for central metabolism, including the Wood-Ljungdahl pathway. PFOR is a member of the 2-oxoacid:ferredoxin oxidoreductase (OFOR) superfamily, which plays major roles in both microbial redox reactions and carbon dioxide fixation. Here, we present a set of crystallographic snapshots of the best-studied member of this superfamily, the PFOR from Moorella thermoacetica (MtPFOR). These snapshots include the native structure, those of lactyl-TPP and acetyl-TPP reaction intermediates, and the first of an OFOR with CoA bound. These structural data reveal the binding site of CoA as domain III, the function of which in OFORs was previously unknown, and establish sequence motifs for CoA binding in the OFOR superfamily. MtPFOR structures further show that domain III undergoes a conformational change upon CoA binding that seals off the active site and positions the thiolate of CoA directly adjacent to the TPP cofactor. These structural findings provide a molecular basis for the experimental observation that CoA binding accelerates catalysis by 105-fold. PMID- 29581265 TI - Circadian clock activity of cryptochrome relies on tryptophan-mediated photoreduction. AB - Cryptochromes (CRYs) entrain the circadian clocks of plants and animals to light. Irradiation of the Drosophila cryptochrome (dCRY) causes reduction of an oxidized flavin cofactor by a chain of conserved tryptophan (Trp) residues. However, it is unclear how redox chemistry within the Trp chain couples to dCRY-mediated signaling. Here, we show that substitutions of four key Trp residues to redox active tyrosine and redox-inactive phenylalanine tune the light sensitivity of dCRY photoreduction, conformational activation, cellular stability, and targeted degradation of the clock protein timeless (TIM). An essential surface Trp gates electron flow into the flavin cofactor, but can be relocated for enhanced photoactivation. Differential effects of Trp-mediated flavin photoreduction on cellular turnover of TIM and dCRY indicate that these activities are separated in time and space. Overall, the dCRY Trp chain has evolutionary importance for light sensing, and its manipulation has implications for optogenetic applications of CRYs. PMID- 29581266 TI - Cracking the social code of speech prosody using reverse correlation. AB - Human listeners excel at forming high-level social representations about each other, even from the briefest of utterances. In particular, pitch is widely recognized as the auditory dimension that conveys most of the information about a speaker's traits, emotional states, and attitudes. While past research has primarily looked at the influence of mean pitch, almost nothing is known about how intonation patterns, i.e., finely tuned pitch trajectories around the mean, may determine social judgments in speech. Here, we introduce an experimental paradigm that combines state-of-the-art voice transformation algorithms with psychophysical reverse correlation and show that two of the most important dimensions of social judgments, a speaker's perceived dominance and trustworthiness, are driven by robust and distinguishing pitch trajectories in short utterances like the word "Hello," which remained remarkably stable whether male or female listeners judged male or female speakers. These findings reveal a unique communicative adaptation that enables listeners to infer social traits regardless of speakers' physical characteristics, such as sex and mean pitch. By characterizing how any given individual's mental representations may differ from this generic code, the method introduced here opens avenues to explore dysprosody and social-cognitive deficits in disorders like autism spectrum and schizophrenia. In addition, once derived experimentally, these prototypes can be applied to novel utterances, thus providing a principled way to modulate personality impressions in arbitrary speech signals. PMID- 29581268 TI - IRF9 and unphosphorylated STAT2 cooperate with NF-kappaB to drive IL6 expression. AB - In response to IFNbeta, the IL6 gene is activated, modestly at early times by ISGF3 (IRF9 plus tyrosine-phosphorylated STATs 1 and 2), and strongly at late times by U-ISGF3 (IRF9 plus U-STATs 1 and 2, lacking tyrosine phosphorylation). A classical IFN-stimulated response element (ISRE) at -1,513 to -1,526 in the human IL6 promoter is required. Pretreating cells with IFNbeta or increasing the expression of U-STAT2 and IRF9 exogenously greatly enhances IL6 expression in response to the classical NF-kappaB activators IL1, TNF, and LPS. U-STAT2 binds tightly to IRF9, the DNA binding subunit of ISGF3, and also to the p65 subunit of NF-kappaB. Therefore, as shown by ChIP analyses, U-STAT2 can bridge the ISRE and kappaB elements in the IL6 promoter. In some cancer cells, the protumorigenic activation of STAT3 will be enhanced by the increased synthesis of IL6 that is facilitated by high expression of U-STAT2 and IRF9. PMID- 29581267 TI - Exploring the structural origins of cryptic sites on proteins. AB - Molecular dynamics (MD) simulations of proteins reveal the existence of many transient surface pockets; however, the factors determining what small subset of these represent druggable or functionally relevant ligand binding sites, called "cryptic sites," are not understood. Here, we examine multiple X-ray structures for a set of proteins with validated cryptic sites, using the computational hot spot identification tool FTMap. The results show that cryptic sites in ligand free structures generally have a strong binding energy hot spot very close by. As expected, regions around cryptic sites exhibit above-average flexibility, and close to 50% of the proteins studied here have unbound structures that could accommodate the ligand without clashes. Nevertheless, the strong hot spot neighboring each cryptic site is almost always exploited by the bound ligand, suggesting that binding may frequently involve an induced fit component. We additionally evaluated the structural basis for cryptic site formation, by comparing unbound to bound structures. Cryptic sites are most frequently occluded in the unbound structure by intrusion of loops (22.5%), side chains (19.4%), or in some cases entire helices (5.4%), but motions that create sites that are too open can also eliminate pockets (19.4%). The flexibility of cryptic sites frequently leads to missing side chains or loops (12%) that are particularly evident in low resolution crystal structures. An interesting observation is that cryptic sites formed solely by the movement of side chains, or of backbone segments with fewer than five residues, result only in low affinity binding sites with limited use for drug discovery. PMID- 29581269 TI - Internal states and extrinsic factors both determine monkey vocal production. AB - A key question for understanding speech evolution is whether or not the vocalizations of our closest living relatives-nonhuman primates-represent the precursors to speech. Some believe that primate vocalizations are not volitional but are instead inextricably linked to internal states like arousal and thus bear little resemblance to human speech. Others disagree and believe that since many primates can use their vocalizations strategically, this demonstrates a degree of voluntary vocal control. In the current study, we present a behavioral paradigm that reliably elicits different types of affiliative vocalizations from marmoset monkeys while measuring their heart rate fluctuations using noninvasive electromyography. By modulating both the physical distance between marmosets and the sensory information available to them, we find that arousal levels are linked, but not inextricably, to vocal production. Different arousal levels are, generally, associated with changes in vocal acoustics and the drive to produce different call types. However, in contexts where marmosets are interacting, the production of these different call types is also affected by extrinsic factors such as the timing of a conspecific's vocalization. These findings suggest that variability in vocal output as a function of context might reflect trade-offs between the drive to perpetuate vocal contact and conserving energy. PMID- 29581270 TI - Kv4.2 autism and epilepsy mutation enhances inactivation of closed channels but impairs access to inactivated state after opening. AB - A de novo mutation in the KCND2 gene, which encodes the Kv4.2 K+ channel, was identified in twin boys with intractable, infant-onset epilepsy and autism. Kv4.2 channels undergo closed-state inactivation (CSI), a mechanism by which channels inactivate without opening during subthreshold depolarizations. CSI dynamically modulates neuronal excitability and action potential back propagation in response to excitatory synaptic input, controlling Ca2+ influx into dendrites and regulating spike timing-dependent plasticity. Here, we show that the V404M mutation specifically affects the mechanism of CSI, enhancing the inactivation of channels that have not opened while dramatically impairing the inactivation of channels that have opened. The mutation gives rise to these opposing effects by increasing the stability of the inactivated state and in parallel, profoundly slowing the closure of open channels, which according to our data, is required for CSI. The larger volume of methionine compared with valine is a major factor underlying altered inactivation gating. Our results suggest that V404M increases the strength of the physical interaction between the pore gate and the voltage sensor regardless of whether the gate is open or closed. Furthermore, in contrast to previous proposals, our data strongly suggest that physical coupling between the voltage sensor and the pore gate is maintained in the inactivated state. The state-dependent effects of V404M on CSI are expected to disturb the regulation of neuronal excitability and the induction of spike timing-dependent plasticity. Our results strongly support a role for altered CSI gating in the etiology of epilepsy and autism in the affected twins. PMID- 29581271 TI - Levy flight movements prevent extinctions and maximize population abundances in fragile Lotka-Volterra systems. AB - Multiple-scale mobility is ubiquitous in nature and has become instrumental for understanding and modeling animal foraging behavior. However, the impact of individual movements on the long-term stability of populations remains largely unexplored. We analyze deterministic and stochastic Lotka-Volterra systems, where mobile predators consume scarce resources (prey) confined in patches. In fragile systems (that is, those unfavorable to species coexistence), the predator species has a maximized abundance and is resilient to degraded prey conditions when individual mobility is multiple scaled. Within the Levy flight model, highly superdiffusive foragers rarely encounter prey patches and go extinct, whereas normally diffusing foragers tend to proliferate within patches, causing extinctions by overexploitation. Levy flights of intermediate index allow a sustainable balance between patch exploitation and regeneration over wide ranges of demographic rates. Our analytical and simulated results can explain field observations and suggest that scale-free random movements are an important mechanism by which entire populations adapt to scarcity in fragmented ecosystems.

PMID- 29581272 TI - Endothelial GqPCR activity controls capillary electrical signaling and brain blood flow through PIP2 depletion. AB - Brain capillaries play a critical role in sensing neural activity and translating it into dynamic changes in cerebral blood flow to serve the metabolic needs of the brain. The molecular cornerstone of this mechanism is the capillary endothelial cell inward rectifier K+ (Kir2.1) channel, which is activated by neuronal activity-dependent increases in external K+ concentration, producing a propagating hyperpolarizing electrical signal that dilates upstream arterioles. Here, we identify a key regulator of this process, demonstrating that phosphatidylinositol 4,5-bisphosphate (PIP2) is an intrinsic modulator of capillary Kir2.1-mediated signaling. We further show that PIP2 depletion through activation of Gq protein-coupled receptors (GqPCRs) cripples capillary-to arteriole signal transduction in vitro and in vivo, highlighting the potential regulatory linkage between GqPCR-dependent and electrical neurovascular-coupling mechanisms. These results collectively show that PIP2 sets the gain of capillary initiated electrical signaling by modulating Kir2.1 channels. Endothelial PIP2 levels would therefore shape the extent of retrograde signaling and modulate cerebral blood flow. PMID- 29581274 TI - Loss of TDP43 inhibits progression of triple-negative breast cancer in coordination with SRSF3. AB - Aberrant alternative splicing has been highlighted as a potential hallmark of cancer. Here, we identify TDP43 (TAR DNA-binding protein 43) as an important splicing regulator responsible for the unique splicing profile in triple-negative breast cancer (TNBC). Clinical data demonstrate that TDP43 is highly expressed in TNBC with poor prognosis. Knockdown of TDP43 inhibits tumor progression, including proliferation and metastasis, and overexpression of TDP43 promotes proliferation and malignancy of mammary epithelial cells. Deep sequencing analysis and functional experiments indicate that TDP43 alters most splicing events with splicing factor SRSF3 (serine/arginine-rich splicing factor 3), in the regulation of TNBC progression. The TDP43/SRSF3 complex controls specific splicing events, including downstream genes PAR3 and NUMB The effect of reduced metastasis and proliferation upon the knockdown of TDP43 or SRSF3 is mediated by the splicing regulation of PAR3 and NUMB exon 12, respectively. The TDP43/SRSF3 complex and downstream PAR3 isoform are potential therapeutic targets for TNBC. PMID- 29581275 TI - IpdAB, a virulence factor in Mycobacterium tuberculosis, is a cholesterol ring cleaving hydrolase. AB - Mycobacterium tuberculosis (Mtb) grows on host-derived cholesterol during infection. IpdAB, found in all steroid-degrading bacteria and a determinant of pathogenicity, has been implicated in the hydrolysis of the last steroid ring. Phylogenetic analyses revealed that IpdAB orthologs form a clade of CoA transferases (CoTs). In a coupled assay with a thiolase, IpdAB transformed the cholesterol catabolite (R)-2-(2-carboxyethyl)-3-methyl-6-oxocyclohex-1-ene-1 carboxyl-CoA (COCHEA-CoA) and CoASH to 4-methyl-5-oxo-octanedioyl-CoA (MOODA-CoA) and acetyl-CoA with high specificity (kcat/Km = 5.8 +/- 0.8 * 104 M-1?s-1). The structure of MOODA-CoA was consistent with IpdAB hydrolyzing COCHEA-CoA to a beta keto-thioester, a thiolase substrate. Contrary to characterized CoTs, IpdAB exhibited no activity toward small CoA thioesters. Further, IpdAB lacks the catalytic glutamate residue that is conserved in the beta-subunit of characterized CoTs and a glutamyl-CoA intermediate was not trapped during turnover. By contrast, Glu105A, conserved in the alpha-subunit of IpdAB, was essential for catalysis. A crystal structure of the IpdAB.COCHEA-CoA complex, solved to 1.4 A, revealed that Glu105A is positioned to act as a catalytic base. Upon titration with COCHEA-CoA, the E105AA variant accumulated a yellow-colored species (lambdamax = 310 nm; Kd = 0.4 +/- 0.2 MUM) typical of beta-keto enolates. In the presence of D2O, IpdAB catalyzed the deuteration of COCHEA-CoA adjacent to the hydroxylation site at rates consistent with kcat Based on these data and additional IpdAB variants, we propose a retro-Claisen condensation-like mechanism for the IpdAB-mediated hydrolysis of COCHEA-CoA. This study expands the range of known reactions catalyzed by the CoT superfamily and provides mechanistic insight into an important determinant of Mtb pathogenesis. PMID- 29581276 TI - Single-nucleotide resolution dynamic repair maps of UV damage in Saccharomyces cerevisiae genome. AB - We have adapted the eXcision Repair-sequencing (XR-seq) method to generate single nucleotide resolution dynamic repair maps of UV-induced cyclobutane pyrimidine dimers and (6-4) pyrimidine-pyrimidone photoproducts in the Saccharomyces cerevisiae genome. We find that these photoproducts are removed from the genome primarily by incisions 13-18 nucleotides 5' and 6-7 nucleotides 3' to the UV damage that generate 21- to 27-nt-long excision products. Analyses of the excision repair kinetics both in single genes and at the genome-wide level reveal strong transcription-coupled repair of the transcribed strand at early time points followed by predominantly nontranscribed strand repair at later stages. We have also characterized the excision repair level as a function of the transcription level. The availability of high-resolution and dynamic repair maps should aid in future repair and mutagenesis studies in this model organism. PMID- 29581278 TI - Rapid enhancement of chemical weathering recorded by extremely light seawater lithium isotopes at the Permian-Triassic boundary. AB - Lithium (Li) isotope analyses of sedimentary rocks from the Meishan section in South China reveal extremely light seawater Li isotopic signatures at the Permian Triassic boundary (PTB), which coincide with the most severe mass extinction in the history of animal life. Using a dynamic seawater lithium box model, we show that the light seawater Li isotopic signatures can be best explained by a significant influx of riverine [Li] with light delta7Li to the ocean realm. The seawater Li isotope excursion started >=300 Ky before and persisted up to the main extinction event, which is consistent with the eruption time of the Siberian Traps. The eruption of the Siberian Traps exposed an enormous amount of fresh basalt and triggered CO2 release, rapid global warming, and acid rains, which in turn led to a rapid enhancement of continental weathering. The enhanced continental weathering delivered excessive nutrients to the oceans that could lead to marine eutrophication, anoxia, acidification, and ecological perturbation, ultimately resulting in the end-Permian mass extinction. PMID- 29581277 TI - Endoplasmic reticulum-localized CCX2 is required for osmotolerance by regulating ER and cytosolic Ca2+ dynamics in Arabidopsis. AB - Ca2+ signals in plant cells are important for adaptive responses to environmental stresses. Here, we report that the Arabidopsis CATION/Ca2+ EXCHANGER2 (CCX2), encoding a putative cation/Ca2+ exchanger that localizes to the endoplasmic reticulum (ER), is strongly induced by salt and osmotic stresses. Compared with the WT, AtCCX2 loss-of-function mutant was less tolerant to osmotic stress and displayed the most noteworthy phenotypes (less root/shoot growth) during salt stress. Conversely, AtCCX2 gain-of-function mutants were more tolerant to osmotic stress. In addition, AtCCX2 partially suppresses the Ca2+ sensitivity of K667 yeast triple mutant, characterized by Ca2+ uptake deficiency. Remarkably, Cameleon Ca2+ sensors revealed that the absence of AtCCX2 activity results in decreased cytosolic and increased ER Ca2+ concentrations in comparison with both WT and the gain-of-function mutants. This was observed in both salt and nonsalt osmotic stress conditions. It appears that AtCCX2 is directly involved in the control of Ca2+ fluxes between the ER and the cytosol, which plays a key role in the ability of plants to cope with osmotic stresses. To our knowledge, Atccx2 is unique as a plant mutant to show a measured alteration in ER Ca2+ concentrations. In this study, we identified the ER-localized AtCCX2 as a pivotal player in the regulation of ER Ca2+ dynamics that heavily influence plant growth upon salt and osmotic stress. PMID- 29581279 TI - Reduction of lipid accumulation rescues Bietti's crystalline dystrophy phenotypes. AB - Bietti's crystalline dystrophy (BCD) is an intractable and progressive chorioretinal degenerative disease caused by mutations in the CYP4V2 gene, resulting in blindness in most patients. Although we and others have shown that retinal pigment epithelium (RPE) cells are primarily impaired in patients with BCD, the underlying mechanisms of RPE cell damage are still unclear because we lack access to appropriate disease models and to lesion-affected cells from patients with BCD. Here, we generated human RPE cells from induced pluripotent stem cells (iPSCs) derived from patients with BCD carrying a CYP4V2 mutation and successfully established an in vitro model of BCD, i.e., BCD patient-specific iPSC-RPE cells. In this model, RPE cells showed degenerative changes of vacuolated cytoplasm similar to those in postmortem specimens from patients with BCD. BCD iPSC-RPE cells exhibited lysosomal dysfunction and impairment of autophagy flux, followed by cell death. Lipidomic analyses revealed the accumulation of glucosylceramide and free cholesterol in BCD-affected cells. Notably, we found that reducing free cholesterol by cyclodextrins or delta tocopherol in RPE cells rescued BCD phenotypes, whereas glucosylceramide reduction did not affect the BCD phenotype. Our data provide evidence that reducing intracellular free cholesterol may have therapeutic efficacy in patients with BCD. PMID- 29581281 TI - Water-like anomalies as a function of tetrahedrality. AB - Tetrahedral interactions describe the behavior of the most abundant and technologically important materials on Earth, such as water, silicon, carbon, germanium, and countless others. Despite their differences, these materials share unique common physical behaviors, such as liquid anomalies, open crystalline structures, and extremely poor glass-forming ability at ambient pressure. To reveal the physical origin of these anomalies and their link to the shape of the phase diagram, we systematically study the properties of the Stillinger-Weber potential as a function of the strength of the tetrahedral interaction [Formula: see text] We uncover a unique transition to a reentrant spinodal line at low values of [Formula: see text], accompanied with a change in the dynamical behavior, from non-Arrhenius to Arrhenius. We then show that a two-state model can provide a comprehensive understanding on how the thermodynamic and dynamic anomalies of this important class of materials depend on the strength of the tetrahedral interaction. Our work establishes a deep link between the shape of the phase diagram and the thermodynamic and dynamic properties through local structural ordering in liquids and hints at why water is so special among all substances.

PMID- 29581280 TI - Chloroplast SRP43 acts as a chaperone for glutamyl-tRNA reductase, the rate limiting enzyme in tetrapyrrole biosynthesis. AB - Assembly of light-harvesting complexes requires synchronization of chlorophyll (Chl) biosynthesis with biogenesis of light-harvesting Chl a/b-binding proteins (LHCPs). The chloroplast signal recognition particle (cpSRP) pathway is responsible for transport of nucleus-encoded LHCPs in the stroma of the plastid and their integration into the thylakoid membranes. Correct folding and assembly of LHCPs require the incorporation of Chls, whose biosynthesis must therefore be precisely coordinated with membrane insertion of LHCPs. How the spatiotemporal coordination between the cpSRP machinery and Chl biosynthesis is achieved is poorly understood. In this work, we demonstrate a direct interaction between cpSRP43, the chaperone that mediates LHCP targeting and insertion, and glutamyl tRNA reductase (GluTR), a rate-limiting enzyme in tetrapyrrole biosynthesis. Concurrent deficiency for cpSRP43 and the GluTR-binding protein (GBP) additively reduces GluTR levels, indicating that cpSRP43 and GBP act nonredundantly to stabilize GluTR. The substrate-binding domain of cpSRP43 binds to the N-terminal region of GluTR, which harbors aggregation-prone motifs, and the chaperone activity of cpSRP43 efficiently prevents aggregation of these regions. Our work thus reveals a function of cpSRP43 in Chl biosynthesis and suggests a striking mechanism for posttranslational coordination of LHCP insertion with Chl biosynthesis. PMID- 29581283 TI - Dependence of the evolution of carbon dynamics in the northern permafrost region on the trajectory of climate change. AB - We conducted a model-based assessment of changes in permafrost area and carbon storage for simulations driven by RCP4.5 and RCP8.5 projections between 2010 and 2299 for the northern permafrost region. All models simulating carbon represented soil with depth, a critical structural feature needed to represent the permafrost carbon-climate feedback, but that is not a universal feature of all climate models. Between 2010 and 2299, simulations indicated losses of permafrost between 3 and 5 million km2 for the RCP4.5 climate and between 6 and 16 million km2 for the RCP8.5 climate. For the RCP4.5 projection, cumulative change in soil carbon varied between 66-Pg C (1015-g carbon) loss to 70-Pg C gain. For the RCP8.5 projection, losses in soil carbon varied between 74 and 652 Pg C (mean loss, 341 Pg C). For the RCP4.5 projection, gains in vegetation carbon were largely responsible for the overall projected net gains in ecosystem carbon by 2299 (8- to 244-Pg C gains). In contrast, for the RCP8.5 projection, gains in vegetation carbon were not great enough to compensate for the losses of carbon projected by four of the five models; changes in ecosystem carbon ranged from a 641-Pg C loss to a 167-Pg C gain (mean, 208-Pg C loss). The models indicate that substantial net losses of ecosystem carbon would not occur until after 2100. This assessment suggests that effective mitigation efforts during the remainder of this century could attenuate the negative consequences of the permafrost carbon-climate feedback. PMID- 29581284 TI - Light-induced dilation in nanosheets of charge-transfer complexes. AB - We report the observation of a sizable photostrictive effect of 5.7% with fast, submillisecond response times, arising from a light-induced lattice dilation of a molecular nanosheet, composed of the molecular charge-transfer compound dibenzotetrathiafulvalene (DBTTF) and C60 An interfacial self-assembly approach is introduced for the thickness-controlled growth of the thin films. From photoabsorption measurements, molecular simulations, and electronic structure calculations, we suggest that photostriction within these films arises from a transformation in the molecular structure of constituent molecules upon photoinduced charge transfer, as well as the accommodation of free charge carriers within the material. Additionally, we find that the photostrictive properties of the nanosheets are thickness-dependent, a phenomenon that we suggest arises from surface-induced conformational disorder in the molecular components of the film. Moreover, because of the molecular structure in the films, which results largely from interactions between the constituent pi-systems and the sulfur atoms of DBTTF, the optoelectronic properties are found to be anisotropic. This work enables the fabrication of 2D molecular charge-transfer nanosheets with tunable thicknesses and properties, suitable for a wide range of applications in flexible electronic technologies. PMID- 29581285 TI - Water-mediated conformational preselection mechanism in substrate binding cooperativity to protein kinase A. AB - Substrate binding cooperativity in protein kinase A (PKA) seems to involve allosteric coupling between the two binding sites. It received significant attention, but its molecular basis still remains not entirely clear. Based on long molecular dynamics of PKA and its complexes, we characterized an allosteric pathway that links ATP binding to the redistribution of states adopted by a protein substrate positioning segment in favor of those that warrant correct binding. We demonstrate that the cooperativity mechanism critically depends on the presence of water in two distinct, buried hydration sites. One holds just a single water molecule, which acts as a switchable hydrogen bond bridge along the allosteric pathway. The second, filled with partially disordered solvent, is essential for providing a smooth free energy landscape underlying conformational transitions of the peptide binding region. Our findings remain in agreement with experimental data, also concerning the cooperativity abolishing effect of the Y204A mutation, and indicate a plausible molecular mechanism contributing to experimentally observed binding cooperativity of the two substrates. PMID- 29581286 TI - Embryophyte stress signaling evolved in the algal progenitors of land plants. AB - Streptophytes are unique among photosynthetic eukaryotes in having conquered land. As the ancestors of land plants, streptophyte algae are hypothesized to have possessed exaptations to the environmental stressors encountered during the transition to terrestrial life. Many of these stressors, including high irradiance and drought, are linked to plastid biology. We have investigated global gene expression patterns across all six major streptophyte algal lineages, analyzing a total of around 46,000 genes assembled from a little more than 1.64 billion sequence reads from six organisms under three growth conditions. Our results show that streptophyte algae respond to cold and high light stress via expression of hallmark genes used by land plants (embryophytes) during stress response signaling and downstream responses. Among the strongest differentially regulated genes were those associated with plastid biology. We observed that among streptophyte algae, those most closely related to land plants, especially Zygnema, invest the largest fraction of their transcriptional budget in plastid targeted proteins and possess an array of land plant-type plastid-nucleus communication genes. Streptophyte algae more closely related to land plants also appear most similar to land plants in their capacity to respond to plastid stressors. Support for this notion comes from the detection of a canonical abscisic acid receptor of the PYRABACTIN RESISTANCE (PYR/PYL/RCAR) family in Zygnema, the first found outside the land plant lineage. We conclude that a fine tuned response toward terrestrial plastid stressors was among the exaptations that allowed streptophytes to colonize the terrestrial habitat on a global scale. PMID- 29581287 TI - Fusogenic micropeptide Myomixer is essential for satellite cell fusion and muscle regeneration. AB - Regeneration of skeletal muscle in response to injury occurs through fusion of a population of stem cells, known as satellite cells, with injured myofibers. Myomixer, a muscle-specific membrane micropeptide, cooperates with the transmembrane protein Myomaker to regulate embryonic myoblast fusion and muscle formation. To investigate the role of Myomixer in muscle regeneration, we used CRISPR/Cas9-mediated genome editing to generate conditional knockout Myomixer alleles in mice. We show that genetic deletion of Myomixer in satellite cells using a tamoxifen-regulated Cre recombinase transgene under control of the Pax7 promoter abolishes satellite cell fusion and prevents muscle regeneration, resulting in severe muscle degeneration after injury. Satellite cells devoid of Myomixer maintain expression of Myomaker, demonstrating that Myomaker alone is insufficient to drive myoblast fusion. These findings, together with prior studies demonstrating the essentiality of Myomaker for muscle regeneration, highlight the obligatory partnership of Myomixer and Myomaker for myofiber formation throughout embryogenesis and adulthood. PMID- 29581288 TI - Small proline-rich protein 2B drives stress-dependent p53 degradation and fibroblast proliferation in heart failure. AB - Heart disease is associated with the accumulation of resident cardiac fibroblasts (CFs) that secrete extracellular matrix (ECM), leading to the development of pathological fibrosis and heart failure. However, the mechanisms underlying resident CF proliferation remain poorly defined. Here, we report that small proline-rich protein 2b (Sprr2b) is among the most up-regulated genes in CFs during heart disease. We demonstrate that SPRR2B is a regulatory subunit of the USP7/MDM2-containing ubiquitination complex. SPRR2B stimulates the accumulation of MDM2 and the degradation of p53, thus facilitating the proliferation of pathological CFs. Furthermore, SPRR2B phosphorylation by nonreceptor tyrosine kinases in response to TGF-beta1 signaling and free-radical production potentiates SPRR2B activity and cell cycle progression. Knockdown of the Sprr2b gene or inhibition of SPRR2B phosphorylation attenuates USP7/MDM2 binding and p53 degradation, leading to CF cell cycle arrest. Importantly, SPRR2B expression is elevated in cardiac tissue from human heart failure patients and correlates with the proliferative state of patient-derived CFs in a process that is reversed by insulin growth factor-1 signaling. These data establish SPRR2B as a unique component of the USP7/MDM2 ubiquitination complex that drives p53 degradation, CF accumulation, and the development of pathological cardiac fibrosis. PMID- 29581289 TI - Energetic tradeoffs control the size distribution of aquatic mammals. AB - Four extant lineages of mammals have invaded and diversified in the water: Sirenia, Cetacea, Pinnipedia, and Lutrinae. Most of these aquatic clades are larger bodied, on average, than their closest land-dwelling relatives, but the extent to which potential ecological, biomechanical, and physiological controls contributed to this pattern remains untested quantitatively. Here, we use previously published data on the body masses of 3,859 living and 2,999 fossil mammal species to examine the evolutionary trajectories of body size in aquatic mammals through both comparative phylogenetic analysis and examination of the fossil record. Both methods indicate that the evolution of an aquatic lifestyle is driving three of the four extant aquatic mammal clades toward a size attractor at ~500 kg. The existence of this body size attractor and the relatively rapid selection toward, and limited deviation from, this attractor rule out most hypothesized drivers of size increase. These three independent body size increases and a shared aquatic optimum size are consistent with control by differences in the scaling of energetic intake and cost functions with body size between the terrestrial and aquatic realms. Under this energetic model, thermoregulatory costs constrain minimum size, whereas limitations on feeding efficiency constrain maximum size. The optimum size occurs at an intermediate value where thermoregulatory costs are low but feeding efficiency remains high. Rather than being released from size pressures, water-dwelling mammals are driven and confined to larger body sizes by the strict energetic demands of the aquatic medium. PMID- 29581290 TI - OSR1 regulates a subset of inward rectifier potassium channels via a binding motif variant. AB - The with-no-lysine (K) (WNK) signaling pathway to STE20/SPS1-related proline- and alanine-rich kinase (SPAK) and oxidative stress-responsive 1 (OSR1) kinase is an important mediator of cell volume and ion transport. SPAK and OSR1 associate with upstream kinases WNK 1-4, substrates, and other proteins through their C-terminal domains which interact with linear R-F-x-V/I sequence motifs. In this study we find that SPAK and OSR1 also interact with similar affinity with a motif variant, R-x-F-x-V/I. Eight of 16 human inward rectifier K+ channels have an R-x-F-x-V motif. We demonstrate that two of these channels, Kir2.1 and Kir2.3, are activated by OSR1, while Kir4.1, which does not contain the motif, is not sensitive to changes in OSR1 or WNK activity. Mutation of the motif prevents activation of Kir2.3 by OSR1. Both siRNA knockdown of OSR1 and chemical inhibition of WNK activity disrupt NaCl-induced plasma membrane localization of Kir2.3. Our results suggest a mechanism by which WNK-OSR1 enhance Kir2.1 and Kir2.3 channel activity by increasing their plasma membrane localization. Regulation of members of the inward rectifier K+ channel family adds functional and mechanistic insight into the physiological impact of the WNK pathway. PMID- 29581291 TI - Divergent trends of open-surface water body area in the contiguous United States from 1984 to 2016. AB - The contiguous United States (CONUS), especially the West, faces challenges of increasing water stress and uncertain impacts of climate change. The historical information of surface water body distribution, variation, and multidecadal trends documented in remote-sensing images can aid in water-resource planning and management, yet is not well explored. Here, we detected open-surface water bodies in all Landsat 5, 7, and 8 images (~370,000 images, >200 TB) of the CONUS and generated 30-meter annual water body frequency maps for 1984-2016. We analyzed the interannual variations and trends of year-long water body area, examined the impacts of climatic and anthropogenic drivers on water body area dynamics, and explored the relationships between water body area and land water storage (LWS). Generally, the western half of the United States is prone to water stress, with small water body area and large interannual variability. During 1984-2016, water poor regions of the Southwest and Northwest had decreasing trends in water body area, while water-rich regions of the Southeast and far north Great Plains had increasing trends. These divergent trends, mainly driven by climate, enlarged water-resource gaps and are likely to continue according to climate projections. Water body area change is a good indicator of LWS dynamics in 58% of the CONUS. Following the 2012 prolonged drought, LWS in California and the southern Great Plains had a larger decrease than surface water body area, likely caused by massive groundwater withdrawals. Our findings provide valuable information for surface water-resource planning and management across the CONUS. PMID- 29581292 TI - Sortase ligation enables homogeneous GPCR phosphorylation to reveal diversity in beta-arrestin coupling. AB - The ability of G protein-coupled receptors (GPCRs) to initiate complex cascades of cellular signaling is governed by the sequential coupling of three main transducer proteins, G protein, GPCR kinase (GRK), and beta-arrestin. Mounting evidence indicates these transducers all have distinct conformational preferences and binding modes. However, interrogating each transducer's mechanism of interaction with GPCRs has been complicated by the interplay of transducer mediated signaling events. For example, GRK-mediated receptor phosphorylation recruits and induces conformational changes in beta-arrestin, which facilitates coupling to the GPCR transmembrane core. Here we compare the allosteric interactions of G proteins and beta-arrestins with GPCRs' transmembrane cores by using the enzyme sortase to ligate a synthetic phosphorylated peptide onto the carboxyl terminus of three different receptors. Phosphopeptide ligation onto the beta2-adrenergic receptor (beta2AR) allows stabilization of a high-affinity receptor active state by beta-arrestin1, permitting us to define elements in the beta2AR and beta-arrestin1 that contribute to the receptor transmembrane core interaction. Interestingly, ligation of the identical phosphopeptide onto the beta2AR, the muscarinic acetylcholine receptor 2 and the MU-opioid receptor reveals that the ability of beta-arrestin1 to enhance agonist binding relative to G protein differs substantially among receptors. Furthermore, strong allosteric coupling of beta-arrestin1 correlates with its ability to attenuate, or "desensitize," G protein activation in vitro. Sortase ligation thus provides a versatile method to introduce complex, defined phosphorylation patterns into GPCRs, and analogous strategies could be applied to other classes of posttranslationally modified proteins. These homogeneously phosphorylated GPCRs provide an innovative means to systematically study receptor-transducer interactions. PMID- 29581293 TI - South American monsoon response to iceberg discharge in the North Atlantic. AB - Heinrich Stadials significantly affected tropical precipitation through changes in the interhemispheric temperature gradient as a result of abrupt cooling in the North Atlantic. Here, we focus on changes in South American monsoon precipitation during Heinrich Stadials using a suite of speleothem records covering the last 85 ky B.P. from eastern South America. We document the response of South American monsoon precipitation to episodes of extensive iceberg discharge, which is distinct from the response to the cooling episodes that precede the main phase of ice-rafted detritus deposition. Our results demonstrate that iceberg discharge in the western subtropical North Atlantic led to an abrupt increase in monsoon precipitation over eastern South America. Our findings of an enhanced Southern Hemisphere monsoon, coeval with the iceberg discharge into the North Atlantic, are consistent with the observed abrupt increase in atmospheric methane concentrations during Heinrich Stadials. PMID- 29581294 TI - Crystal structure of human lysyl oxidase-like 2 (hLOXL2) in a precursor state. AB - Lysyl oxidases (LOXs), a type of copper- and lysyl tyrosylquinone (LTQ) dependent amine oxidase, catalyze the oxidative deamination of lysine residues of extracellular matrix (ECM) proteins such as elastins and collagens and generate aldehyde groups. The oxidative deamination of lysine represents the foundational step for the cross-linking of elastin and collagen and thus is crucial for ECM modeling. Despite their physiological significance, the structure of this important family of enzymes remains elusive. Here we report the crystal structure of human lysyl oxidase-like 2 (hLOXL2) at 2.4-A resolution. Unexpectedly, the copper-binding site of hLOXL2 is occupied by zinc, which blocks LTQ generation and the enzymatic activity of hLOXL2 in our in vitro assay. Biochemical analysis confirms that copper loading robustly activates hLOXL2 and supports LTQ formation. Furthermore, the LTQ precursor residues in the structure are distanced by 16.6 A, corroborating the notion that the present structure may represent a precursor state and that pronounced conformational rearrangements would be required for protein activation. The structure presented here establishes an important foundation for understanding the structure-function relationship of LOX proteins and will facilitate LOX-targeting drug discovery. PMID- 29581295 TI - Amide-forming chemical ligation via O-acyl hydroxamic acids. AB - The facile rearrangement of "S-acyl isopeptides" to native peptide bonds via S,N acyl shift is central to the success of native chemical ligation, the widely used approach for protein total synthesis. Proximity-driven amide bond formation via acyl transfer reactions in other contexts has proven generally less effective. Here, we show that under neutral aqueous conditions, "O-acyl isopeptides" derived from hydroxy-asparagine [aspartic acid-beta-hydroxamic acid; Asp(beta-HA)] rearrange to form native peptide bonds via an O,N-acyl shift. This process constitutes a rare example of an O,N-acyl shift that proceeds rapidly across a medium-size ring (t1/2 ~ 15 min), and takes place in water with minimal interference from hydrolysis. In contrast to serine/threonine or tyrosine, which form O-acyl isopeptides only by the use of highly activated acyl donors and appropriate protecting groups in organic solvent, Asp(beta-HA) is sufficiently reactive to form O-acyl isopeptides by treatment with an unprotected peptide alphathioester, at low mM concentration, in water. These findings were applied to an acyl transfer-based chemical ligation strategy, in which an unprotected N terminal Asp(beta-HA)-peptide and peptide-alphathioester react under aqueous conditions to give a ligation product ultimately linked by a native peptide bond. PMID- 29581296 TI - Recombinant immunotoxins with albumin-binding domains have long half-lives and high antitumor activity. AB - Recombinant immunotoxins (RITs) are chimeric proteins consisting of a Fv that binds to a cancer cell and a portion of a protein toxin. One of these, Moxetumomab pasudotox, was shown to be effective in treating patients with some leukemias, where the cells are readily accessible to the RIT. However, their short half-life limits their efficacy in solid tumors, because penetration into the tumors is slow. Albumin and agents bound to albumin have a long half-life in the circulation. To increase the time tumor cells are exposed to RITs, we have produced and evaluated variants that contain either an albumin-binding domain (ABD) from Streptococcus or single-domain antibodies from Llama. We have inserted these ABDs into RITs targeting mesothelin, between the Fv and the furin cleavage site. We find that these proteins can be produced in large amounts, are very cytotoxic to mesothelin-expressing cancer cell lines, and have a high affinity for human or mouse serum albumin. In mice, the RIT containing an ABD from Streptococcus has a longer half-life and higher antitumor activity than the other two. Its half-life in the circulation of mice ranges from 113 to 194 min compared with 13 min for an RIT with no ABD. Cell uptake studies show the RIT enters the target cell bound to serum albumin. We conclude that RITs with improved half lives and antitumor activity should be evaluated for the treatment of cancer in humans. PMID- 29581297 TI - Inhibition of Enhancer of zeste homolog 2 (EZH2) induces natural killer cell mediated eradication of hepatocellular carcinoma cells. AB - Natural killer (NK) cell-mediated tumor cell eradication could inhibit tumor initiation and progression. However, the factors that regulate NK cell-mediated cancer cell eradication remain unclear. We determined that hepatocellular carcinoma (HCC) cells exhibit transcriptional down-regulation of NK group 2D (NKG2D) ligands and are largely resistant to NK cell-mediated eradication. Because the down-regulation of NKG2D ligands occurred at the transcriptional level, we tested 32 chemical inhibitors of epigenetic regulators for their ability to re-express NKG2D ligands and enhance HCC cell eradication by NK cells and found that Enhancer of zeste homolog 2 (EZH2) was a transcriptional repressor of NKG2D ligands. The inhibition of EZH2 by small-molecule inhibitors or genetic means enhanced HCC cell eradication by NK cells in a NKG2D ligand-dependent manner. Collectively, these results demonstrate that EZH2 inhibition enhances HCC eradication by NK cells and that EZH2 functions, in part, as an oncogene by inhibiting immune response. PMID- 29581298 TI - RNA-mediated gene regulation is less evolvable than transcriptional regulation. AB - Much of gene regulation is carried out by proteins that bind DNA or RNA molecules at specific sequences. One class of such proteins is transcription factors, which bind short DNA sequences to regulate transcription. Another class is RNA binding proteins, which bind short RNA sequences to regulate RNA maturation, transport, and stability. Here, we study the robustness and evolvability of these regulatory mechanisms. To this end, we use experimental binding data from 172 human and fruit fly transcription factors and RNA binding proteins as well as human polymorphism data to study the evolution of binding sites in vivo. We find little difference between the robustness of regulatory protein-RNA interactions and transcription factor-DNA interactions to DNA mutations. In contrast, we find that RNA-mediated regulation is less evolvable than transcriptional regulation, because mutations are less likely to create interactions of an RNA molecule with a new RNA binding protein than they are to create interactions of a gene regulatory region with a new transcription factor. Our observations are consistent with the high level of conservation observed for interactions between RNA binding proteins and their target molecules as well as the evolutionary plasticity of regulatory regions bound by transcription factors. They may help explain why transcriptional regulation is implicated in many more evolutionary adaptations and innovations than RNA-mediated gene regulation. PMID- 29581299 TI - MDMX acidic domain inhibits p53 DNA binding in vivo and regulates tumorigenesis. AB - The MDM2 homolog MDMX oncoprotein is indispensable for inhibition of p53 during normal embryonic development and malignant transformation, yet how MDMX harnesses p53 functions is unclear. In addition to a canonical N-terminal p53-binding domain, recent work suggests the central acidic domain of MDMX regulates p53 interaction through intramolecular mimicry and engages in second-site interaction with the p53 core domain in vitro. To test the physiological relevance of these interactions, we generated an MDMX knockin mouse having substitutions in a conserved WW motif necessary for these functions (W201S/W202G). Notably, MDMXSG cells have normal p53 level but increased p53 DNA binding and target gene expression, and rapidly senesce. In vivo, MDMXSG inhibits early-phase disease in Eu-Myc transgenic mice but accelerates the onset of lethal lymphoma and shortens overall survival. Therefore, MDMX is an important regulator of p53 DNA binding, which complements the role of MDM2 in regulating p53 level. Furthermore, the results suggest that the WW motif has dual functions that regulate p53 and inhibit Myc-driven lymphomas independent of p53. PMID- 29581301 TI - Escalation of competition into conflict in competitive networks of Formula One drivers. AB - This article investigates the factors that escalate competition into dangerous conflict. Recent sociological theorizing claims that such escalations are particularly likely in dyads of structurally equivalent people (i.e., actors who have the same relations with the same third parties). Using panel data on Formula One races from 1970 through 2014, we model the probability that two drivers collide on the racetrack (an observable trace of conflict) as a function of their structural equivalence in a dynamic network of competitive relationships. Our main hypothesis, that the likelihood of conflict rises with structural equivalence, receives empirical support. Our findings also show that the positive association between structural equivalence and conflict is neither merely a matter of contention for official position nor an artifact of inherently hostile parties spatially exposed to each other. Our analyses further reveal that this positive association is concentrated in a number of theoretically predictable conditions: among age-similar dyads, among stronger performers, in stable competitive networks, and in safe, rather than dangerous, weather conditions. Implications for future research on conflict, networks, and tournaments are discussed. PMID- 29581300 TI - BACE1 SUMOylation increases its stability and escalates the protease activity in Alzheimer's disease. AB - Amyloid beta (Abeta) is a major pathological marker in Alzheimer's disease (AD), which is principally regulated by the rate-limiting beta-secretase (i.e., BACE1) cleavage of amyloid precursor protein (APP). However, how BACE1 activity is posttranslationally regulated remains incompletely understood. Here, we show that BACE1 is predominantly SUMOylated at K501 residue, which escalates its protease activity and stability and subsequently increases Abeta production, leading to cognitive defect seen in the AD mouse model. Compared with a non-SUMOylated K501R mutant, injection of wild-type BACE1 significantly increases Abeta production and triggers cognitive dysfunction. Furthermore, overexpression of wild-type BACE1, but not non-SUMOylated K501R mutant, facilitates senile plaque formation and aggravates the cognitive deficit seen in the APP/PS1 AD mouse model. Together, our data strongly suggest that K501 SUMOylation on BACE1 plays a critical role in mediating its stability and enzymatic activity. PMID- 29581302 TI - New tRNA contacts facilitate ligand binding in a Mycobacterium smegmatis T box riboswitch. AB - T box riboswitches are RNA regulatory elements widely used by organisms in the phyla Firmicutes and Actinobacteria to regulate expression of amino acid-related genes. Expression of T box family genes is down-regulated by transcription attenuation or inhibition of translation initiation in response to increased charging of the cognate tRNA. Three direct contacts with tRNA have been described; however, one of these contacts is absent in a subclass of T box RNAs and the roles of several structural domains conserved in most T box RNAs are unknown. In this study, structural elements of a Mycobacterium smegmatis ileS T box riboswitch variant with an Ultrashort (US) Stem I were sequentially deleted, which resulted in a progressive decrease in binding affinity for the tRNAIle ligand. Selective 2'-hydroxyl acylation analyzed by primer extension (SHAPE) revealed structural changes in conserved riboswitch domains upon interaction with the tRNA ligand. Cross-linking and mutational analyses identified two interaction sites, one between the S-turn element in Stem II and the T arm of tRNAIle and the other between the Stem IIA/B pseudoknot and the D loop of tRNAIle These newly identified RNA contacts add information about tRNA recognition by the T box riboswitch and demonstrate a role for the S-turn and pseudoknot elements, which resemble structural elements that are common in many cellular RNAs. PMID- 29581303 TI - Structural basis for the ethanol action on G-protein-activated inwardly rectifying potassium channel 1 revealed by NMR spectroscopy. AB - Ethanol consumption leads to a wide range of pharmacological effects by acting on the signaling proteins in the human nervous system, such as ion channels. Despite its familiarity and biological importance, very little is known about the molecular mechanisms underlying the ethanol action, due to extremely weak binding affinity and the dynamic nature of the ethanol interaction. In this research, we focused on the primary in vivo target of ethanol, G-protein-activated inwardly rectifying potassium channel (GIRK), which is responsible for the ethanol-induced analgesia. By utilizing solution NMR spectroscopy, we characterized the changes in the structure and dynamics of GIRK induced by ethanol binding. We demonstrated here that ethanol binds to GIRK with an apparent dissociation constant of 1.0 M and that the actual physiological binding site of ethanol is located on the cavity formed between the neighboring cytoplasmic regions of the GIRK tetramer. From the methyl-based NMR relaxation analyses, we revealed that ethanol activates GIRK by shifting the conformational equilibrium processes, which are responsible for the gating of GIRK, to stabilize an open conformation of the cytoplasmic ion gate. We suggest that the dynamic molecular mechanism of the ethanol-induced activation of GIRK represents a general model of the ethanol action on signaling proteins in the human nervous system. PMID- 29581304 TI - Identifying psychological responses of stigmatized groups to referendums. AB - Public votes and referendums on the rights of marginalized communities are utilized in 27 states and occur with some regularity. However, research has only recently begun to examine the psychological consequences of these voter referendums for members of stigmatized groups, and a number of important questions remain regarding the internal validity and generalizability of the existing evidence. The current study advances this literature by combining survey data from a large probability-based sample conducted in 2012 [lesbian, gay, bisexual, and/or transgender (LGBT) n = 939; non-LGBT n = 31,067] with media market ad-buy data in states where marriage equality was on the ballot. Television media markets cross state boundaries, ensuring that there was an unintended group of people in 12 states who were exposed to the same-sex marriage discourse but who did not live in states with the voter referendum ("media market spillovers"). We take advantage of this unique data structure by comparing LGBT people in the media market spillovers to those residing in the same state but in nonspillover markets with no ad exposure. LGBT people are emotionally affected by these campaigns, and non-LGBT people are unaffected. LGBT people in markets with a cumulative total of 400 ads have a 34.0% greater probability of reporting stress than LGBT people not exposed to ads. Additionally, while the negative ads evoked sadness, positive ads evoked enjoyment and happiness. Thus, public votes on minority rights represent both a source of minority stress and resilience. PMID- 29581305 TI - Everolimus rescues multiple cellular defects in laminopathy-patient fibroblasts. AB - LMNA encodes the A-type lamins that are part of the nuclear scaffold. Mutations in LMNA can cause a variety of disorders called laminopathies, including Hutchinson-Gilford progeria syndrome (HGPS), atypical Werner syndrome, and Emery Dreifuss muscular dystrophy. Previous work has shown that treatment of HGPS cells with the mTOR inhibitor rapamycin or with the rapamycin analog everolimus corrects several of the phenotypes seen at the cellular level-at least in part by increasing autophagy and reducing the amount of progerin, the toxic form of lamin A that is overproduced in HGPS patients. Since other laminopathies also result in production of abnormal and potentially toxic lamin proteins, we hypothesized that everolimus would also be beneficial in those disorders. To test this, we applied everolimus to fibroblast cell lines from six laminopathy patients, each with a different mutation in LMNA Everolimus treatment increased proliferative ability and delayed senescence in all cell lines. In several cell lines, we observed that with treatment, there is a significant improvement in nuclear blebbing, which is a cellular hallmark of HGPS and other lamin disorders. These preclinical results suggest that everolimus might have clinical benefit for multiple laminopathy syndromes. PMID- 29581306 TI - Cross-linking of Orai1 channels by STIM proteins. AB - The transmembrane docking of endoplasmic reticulum (ER) Ca2+-sensing STIM proteins with plasma membrane (PM) Orai Ca2+ channels is a critical but poorly understood step in Ca2+ signal generation. STIM1 protein dimers unfold to expose a discrete STIM-Orai activating region (SOAR1) that tethers and activates Orai1 channels within discrete ER-PM junctions. We reveal that each monomer within the SOAR dimer interacts independently with single Orai1 subunits to mediate cross linking between Orai1 channels. Superresolution imaging and mobility measured by fluorescence recovery after photobleaching reveal that SOAR dimer cross-linking leads to substantial Orai1 channel clustering, resulting in increased efficacy and cooperativity of Orai1 channel function. A concatenated SOAR1 heterodimer containing one monomer point mutated at its critical Orai1 binding residue (F394H), although fully activating Orai channels, is completely defective in cross-linking Orai1 channels. Importantly, the naturally occurring STIM2 variant, STIM2.1, has an eight-amino acid insert in its SOAR unit that renders it functionally identical to the F394H mutant in SOAR1. Contrary to earlier predictions, the SOAR1-SOAR2.1 heterodimer fully activates Orai1 channels but prevents cross-linking and clustering of channels. Interestingly, combined expression of full-length STIM1 with STIM2.1 in a 5:1 ratio causes suppression of sustained agonist-induced Ca2+ oscillations and protects cells from Ca2+ overload, resulting from high agonist-induced Ca2+ release. Thus, STIM2.1 exerts a powerful regulatory effect on signal generation likely through preventing Orai1 channel cross-linking. Overall, STIM-mediated cross-linking of Orai1 channels is a hitherto unrecognized functional paradigm that likely provides an organizational microenvironment within ER-PM junctions with important functional impact on Ca2+ signal generation.

AB - Bipartite expression systems, such as the GAL4-UAS system, allow fine manipulation of gene expression and are powerful tools for interrogating gene function. Recently, we established cGAL, a GAL4-based bipartite expression system for transgene control in Caenorhabditis elegans, where a single promoter dictates the expression pattern of a cGAL driver, which then binds target upstream activation sequences to drive expression of a downstream effector gene. Here, we report a split strategy for cGAL using the split intein gp41-1 for intersectional control of transgene expression. Split inteins are protein domains that associate, self-excise, and covalently ligate their flanking peptides together. We split the DNA binding domain and transcriptional activation domain of cGAL and fused them to the N terminal of gp41-1-N-intein and the C terminal of gp41-1-C intein, respectively. In cells where both halves of cGAL are expressed, a functional cGAL driver is reconstituted via intein-mediated protein splicing. This reconstitution allows expression of the driver to be dictated by two promoters for refined spatial control or spatiotemporal control of transgene expression. We apply the split cGAL system to genetically access the single pair of MC neurons (previously inaccessible with a single promoter), and reveal an important role of protein kinase A in rhythmic pharyngeal pumping in C. elegans Thus, the split cGAL system gives researchers a greater degree of spatiotemporal control over transgene expression, and will be a valuable genetic tool in C. elegans for dissecting gene function with finer cell-specific resolution. PMID- 29581307 TI - Structural determinants and cellular environment define processed actin as the sole substrate of the N-terminal acetyltransferase NAA80. AB - N-terminal (Nt) acetylation is a major protein modification catalyzed by N terminal acetyltransferases (NATs). Methionine acidic N termini, including actin, are cotranslationally Nt acetylated by NatB in all eukaryotes, but animal actins containing acidic N termini, are additionally posttranslationally Nt acetylated by NAA80. Actin Nt acetylation was found to regulate cytoskeletal dynamics and motility, thus making NAA80 a potential target for cell migration regulation. In this work, we developed potent and selective bisubstrate inhibitors for NAA80 and determined the crystal structure of NAA80 in complex with such an inhibitor, revealing that NAA80 adopts a fold similar to other NAT enzymes but with a more open substrate binding region. Furthermore, in contrast to most other NATs, the substrate specificity of NAA80 is mainly derived through interactions between the enzyme and the acidic amino acids at positions 2 and 3 of the actin substrate and not residues 1 and 2. A yeast model revealed that ectopic expression of NAA80 in a strain lacking NatB activity partially restored Nt acetylation of NatB substrates, including yeast actin. Thus, NAA80 holds intrinsic capacity to posttranslationally Nt acetylate NatB-type substrates in vivo. In sum, the presence of a dominant cotranslational NatB in all eukaryotes, the specific posttranslational actin methionine removal in animals, and finally, the unique structural features of NAA80 leave only the processed actins as in vivo substrates of NAA80. Together, this study reveals the molecular and cellular basis of NAA80 Nt acetylation and provides a scaffold for development of inhibitors for the regulation of cytoskeletal properties.

AB - The jointed appendages of arthropods have facilitated the spectacular diversity and success of this phylum. Key to the regulation of appendage outgrowth is the Kruppel-like factor (KLF)/specificity protein (Sp) family of zinc finger transcription factors. In the fruit fly, Drosophila melanogaster, the Sp6-9 homolog is activated by Wnt-1/wingless (wg) and establishes ventral appendage (leg) fate. Subsequently, Sp6-9 maintains expression of the axial patterning gene Distal-less (Dll), which promotes limb outgrowth. Intriguingly, in spiders, Dll has been reported to have a derived role as a segmentation gap gene, but the evolutionary origin and regulation of this function are not understood because functional investigations of the appendage-patterning regulatory network are restricted to insects. We tested the evolutionary conservation of the ancestral appendage-patterning network of arthropods with a functional approach in the spider. RNAi-mediated knockdown of the spider Sp6-9 ortholog resulted in diminution or loss of Dll expression and truncation of appendages, as well as loss of the two body segments specified by the early Dll function. In reciprocal experiments, Dll is shown not to be required for Sp6-9 expression. Knockdown of arrow (Wnt-1 coreceptor) disrupted segmentation and appendage development but did not affect the early Sp6-9 expression domain. Ectopic appendages generated in the spider "abdomen" by knockdown of the Hox gene Antennapedia-1 (Antp-1) expressed Sp6-9 comparably to wild-type walking legs. Our results support (i) the evolutionary conservation of an appendage-patterning regulatory network that includes canonical Wnt signaling, Sp6-9, and Dll and (ii) the cooption of the Sp6 9/Dll regulatory cassette in arachnid head segmentation. PMID- 29581311 TI - Processes and patterns of interaction as units of selection: An introduction to ITSNTS thinking. AB - Many practicing biologists accept that nothing in their discipline makes sense except in the light of evolution, and that natural selection is evolution's principal sense-maker. But what natural selection actually is (a force or a statistical outcome, for example) and the levels of the biological hierarchy (genes, organisms, species, or even ecosystems) at which it operates directly are still actively disputed among philosophers and theoretical biologists. Most formulations of evolution by natural selection emphasize the differential reproduction of entities at one or the other of these levels. Some also recognize differential persistence, but in either case the focus is on lineages of material things: even species can be thought of as spatiotemporally restricted, if dispersed, physical beings. Few consider-as "units of selection" in their own right-the processes implemented by genes, cells, species, or communities. "It's the song not the singer" (ITSNTS) theory does that, also claiming that evolution by natural selection of processes is more easily understood and explained as differential persistence than as differential reproduction. ITSNTS was formulated as a response to the observation that the collective functions of microbial communities (the songs) are more stably conserved and ecologically relevant than are the taxa that implement them (the singers). It aims to serve as a useful corrective to claims that "holobionts" (microbes and their animal or plant hosts) are aggregate "units of selection," claims that often conflate meanings of that latter term. But ITSNS also seems broadly applicable, for example, to the evolution of global biogeochemical cycles and the definition of ecosystem function. PMID- 29581310 TI - Adeno-associated virus Rep proteins antagonize phosphatase PP1 to counteract KAP1 repression of the latent viral genome. AB - Adeno-associated virus (AAV) is a small human Dependovirus whose low immunogenicity and capacity for long-term persistence have led to its widespread use as vector for gene therapy. Despite great recent successes in AAV-based gene therapy, further improvements in vector technology may be hindered by an inadequate understanding of various aspects of basic AAV biology. AAV is unique in that its replication is largely dependent on a helper virus and cellular factors. In the absence of helper virus coinfection, wild-type AAV establishes latency through mechanisms that are not yet fully understood. Challenging the currently held model for AAV latency, we show here that the corepressor Kruppel associated box domain-associated protein 1 (KAP1) binds the latent AAV2 genome at the rep ORF, leading to trimethylation of AAV2-associated histone 3 lysine 9 and that the inactivation of KAP1 repression is necessary for AAV2 reactivation and replication. We identify a viral mechanism for the counteraction of KAP1 in which interference with the KAP1 phosphatase protein phosphatase 1 (PP1) by the AAV2 Rep proteins mediates enhanced phosphorylation of KAP1-S824 and thus relief from KAP1 repression. Furthermore, we show that this phenomenon involves recruitment of the NIPP1 (nuclear inhibitor of PP1)-PP1alpha holoenzyme to KAP1 in a manner dependent upon the NIPP1 FHA domain, identifying NIPP1 as an interaction partner for KAP1 and shedding light on the mechanism through which PP1 regulates cellular KAP1 activity. PMID- 29581313 TI - Grassland biodiversity can pay. AB - The biodiversity-ecosystem functioning (BEF) literature provides strong evidence of the biophysical basis for the potential profitability of greater diversity but does not address questions of optimal management. BEF studies typically focus on the ecosystem outputs produced by randomly assembled communities that only differ in their biodiversity levels, measured by indices such as species richness. Landholders, however, do not randomly select species to plant; they choose particular species that collectively maximize profits. As such, their interest is not in comparing the average performance of randomly assembled communities at each level of biodiversity but rather comparing the best-performing communities at each diversity level. Assessing the best-performing mixture requires detailed accounting of species' identities and relative abundances. It also requires accounting for the financial cost of individual species' seeds, and the economic value of changes in the quality, quantity, and variability of the species' collective output-something that existing multifunctionality indices fail to do. This study presents an assessment approach that integrates the relevant factors into a single, coherent framework. It uses ecological production functions to inform an economic model consistent with the utility-maximizing decisions of a potentially risk-averse private landowner. We demonstrate the salience and applicability of the framework using data from an experimental grassland to estimate production relationships for hay and carbon storage. For that case, our results suggest that even a risk-neutral, profit-maximizing landowner would favor a highly diverse mix of species, with optimal species richness falling between the low levels currently found in commercial grasslands and the high levels found in natural grasslands.

AB - S-nitrosylation, a prototypic redox-based posttranslational modification, is frequently dysregulated in disease. S-nitrosoglutathione reductase (GSNOR) regulates protein S-nitrosylation by functioning as a protein denitrosylase. Deficiency of GSNOR results in tumorigenesis and disrupts cellular homeostasis broadly, including metabolic, cardiovascular, and immune function. Here, we demonstrate that GSNOR expression decreases in primary cells undergoing senescence, as well as in mice and humans during their life span. In stark contrast, exceptionally long-lived individuals maintain GSNOR levels. We also show that GSNOR deficiency promotes mitochondrial nitrosative stress, including excessive S-nitrosylation of Drp1 and Parkin, thereby impairing mitochondrial dynamics and mitophagy. Our findings implicate GSNOR in mammalian longevity, suggest a molecular link between protein S-nitrosylation and mitochondria quality control in aging, and provide a redox-based perspective on aging with direct therapeutic implications.

PMID- 29581340 TI - Arterial Wall Imaging in Pediatric Stroke. AB - BACKGROUND AND PURPOSE: Arteriopathy is common in childhood arterial ischemic stroke (AIS) and predicts stroke recurrence. Currently available vascular imaging techniques mainly image the arterial lumen rather than the vessel wall and have a limited ability to differentiate among common arteriopathies. We aimed to investigate the value of a magnetic resonance imaging-based technique, namely noninvasive arterial wall imaging (AWI), for distinguishing among arteriopathy subtypes in a consecutive cohort of children presenting with AIS. METHODS: Children with confirmed AIS and magnetic resonance angiography underwent 3-Tesla AWI including T1-weighted 2-dimensional fluid-attenuated inversion recovery fast spin echo sequences pre- and post-gadolinium contrast. AWI characteristics, including wall enhancement, wall thickening, and luminal stenosis, were documented for all. RESULTS: Twenty-six children with AIS had AWI. Of these, 9 (35%) had AWI enhancement. AWI enhancement was associated with anterior circulation magnetic resonance angiography abnormality and cortical infarction in 8 of 9 (89%) children and normal magnetic resonance angiography with posterior circulation subcortical infarction in 1 (1 of 9; 11%) child. AWI enhancement was not seen in 17 (65%), 10 (59%) of whom had an abnormal magnetic resonance angiography. Distinct patterns of pre- and postcontrast signal abnormality were demonstrated in the vessel wall in the region of interest in children with transient cerebral arteriopathy, arterial dissection, primary central nervous system angiitis, dissecting aneurysm, and cardioembolic stroke. CONCLUSIONS: AWI is a noninvasive, high-resolution magnetic resonance AWI technique, which can be successfully used in children presenting with AIS. Patterns of AWI enhancement are recognizable and associated with specific AIS pathogeneses. Further studies are required to assess the additional diagnostic utility of AWI over routine vascular imaging techniques, in childhood AIS. PMID- 29581341 TI - Time From Imaging to Endovascular Reperfusion Predicts Outcome in Acute Stroke. AB - BACKGROUND AND PURPOSE: This study aims to describe the relationship between computed tomographic (CT) perfusion (CTP)-to-reperfusion time and clinical and radiological outcomes, in a cohort of patients who achieve successful reperfusion for acute ischemic stroke. METHODS: We included data from the CRISP (Computed Tomographic Perfusion to Predict Response in Ischemic Stroke Project) in which all patients underwent a baseline CTP scan before endovascular therapy. Patients were included if they had a mismatch on their baseline CTP scan and achieved successful endovascular reperfusion. Patients with mismatch were categorized into target mismatch and malignant mismatch profiles, according to the volume of their Tmax >10s lesion volume (target mismatch, <100 mL; malignant mismatch, >100 mL). We investigated the impact of CTP-to-reperfusion times on probability of achieving functional independence (modified Rankin Scale, 0-2) at day 90 and radiographic outcomes at day 5. RESULTS: Of 156 included patients, 108 (59%) had the target mismatch profile, and 48 (26%) had the malignant mismatch profile. In patients with the target mismatch profile, CTP-to-reperfusion time showed no association with functional independence (P=0.84), whereas in patients with malignant mismatch profile, CTP-to-reperfusion time was strongly associated with lower probability of functional independence (odds ratio, 0.08; P=0.003). Compared with patients with target mismatch, those with the malignant mismatch profile had significantly more infarct growth (90 [49-166] versus 43 [18-81] mL; P=0.006) and larger final infarct volumes (110 [61-155] versus 48 [21-99] mL; P=0.001). CONCLUSIONS: Compared with target mismatch patients, those with the malignant profile experience faster infarct growth and a steeper decline in the odds of functional independence, with longer delays between baseline imaging and reperfusion. However, this does not exclude the possibility of treatment benefit in patients with a malignant profile. PMID- 29581342 TI - Rescue Stenting for Failed Mechanical Thrombectomy in Acute Ischemic Stroke: A Multicenter Experience. AB - BACKGROUND AND PURPOSE: Effective rescue treatment has not yet been suggested in patients with mechanical thrombectomy (MT) failure. This study aimed to test whether rescue stenting (RS) improved clinical outcomes in MT-failed patients. METHODS: This is a retrospective analysis of the cohorts of the 16 comprehensive stroke centers between September 2010 and December 2015. We identified the patients who underwent MT but failed to recanalize intracranial internal carotid artery or middle cerebral artery M1 occlusion. Patients were dichotomized into 2 groups: patients with RS and without RS after MT failure. Clinical and laboratory findings and outcomes were compared between the 2 groups. It was tested whether RS is associated with functional outcome. RESULTS: MT failed in 148 (25.0%) of the 591 patients with internal carotid artery or middle cerebral artery M1 occlusion. Of these 148 patients, 48 received RS (RS group) and 100 were left without further treatment (no stenting group). Recanalization was successful in 64.6% (31 of 48 patients) of RS group. Compared with no stenting group, RS group showed a significantly higher rate of good outcome (modified Rankin Scale score, 0-2; 39.6% versus 22.0%; P=0.031) without increasing symptomatic intracranial hemorrhage (16.7% versus 20.0%; P=0.823) or mortality (12.5% versus 19.0%; P=0.360). Of the RS group, patients who had recanalization success had 54.8% of good outcome, which is comparable to that (55.4%) of recanalization success group with MT. RS remained independently associated with good outcome after adjustment of other factors (odds ratio, 3.393; 95% confidence interval, 1.192-9.655; P=0.022). Follow-up vascular imaging was available in the 23 (74.2%) of 31 patients with recanalization success with RS. The stent was patent in 20 (87.0%) of the 23 patients. Glycoprotein IIb/IIIa inhibitor was significantly associated with stent patency but not with symptomatic intracranial hemorrhage. CONCLUSIONS: RS was independently associated with good outcomes without increasing symptomatic intracranial hemorrhage or mortality. RS seemed considered in MT-failed internal carotid artery or middle cerebral artery M1 occlusion. PMID- 29581343 TI - Risk Factors for Poststroke Cognitive Decline: The REGARDS Study (Reasons for Geographic and Racial Differences in Stroke). AB - BACKGROUND AND PURPOSE: Poststroke cognitive decline causes disability. Risk factors for poststroke cognitive decline independent of survivors' prestroke cognitive trajectories are uncertain. METHODS: Among 22 875 participants aged >=45 years without baseline cognitive impairment from the REGARDS cohort (Reasons for Geographic and Racial Differences in Stroke), enrolled from 2003 to 2007 and followed through September 2015, we measured the effect of incident stroke (n=694) on changes in cognitive functions and cognitive impairment (Six-Item Screener score <5) and tested whether patient factors modified the effect. Median follow-up was 8.2 years. RESULTS: Incident stroke was associated with acute declines in global cognition, new learning, verbal memory, and executive function. Acute declines in global cognition after stroke were greater in survivors who were black (P=0.04), men (P=0.04), and had cardioembolic (P=0.001) or large artery stroke (P=0.001). Acute declines in executive function after stroke were greater in survivors who had =6. Further clinical trial-specific selection criteria were applied based on the presence of large vessel occlusion, baseline modified Rankin Scale score, core infarct, and perfusion imaging (when available). There were 45 patients who met all DAWN trial criteria and 47 to 58 patients who would meet DEFUSE-3 trial criteria. Thirty-three percent of DAWN-eligible patients are DEFUSE-3 ineligible. CONCLUSIONS: Of all patients with acute ischemic stroke presenting to a single comprehensive stroke center, 1.7% of patients qualified for DAWN clinical trial enrollment with an additional 0.6% to 1% qualifying for the DEFUSE-3 trial. These data predict an increase in thrombectomy utilization with important implications for comprehensive stroke center resource optimization and stroke systems of care. PMID- 29581345 TI - Ischemic Stroke Alters the Expression of the Transcribed Ultraconserved Regions of the Genome in Rat Brain. AB - BACKGROUND AND PURPOSE: Human and rodent genomes diverged ~75 million years ago. However, 481 regions of their genomes (200-779 nucleotide each) remained absolutely conserved and form noncoding RNAs known as transcribed ultraconserved regions (T-UCRs). The functional significance of T-UCRs is not apparent, but their altered expression is associated with many diseases, and thus thought to be critical for life. We presently investigated the poststroke temporal changes in the expression of T-UCRs with potential functional significance. METHODS: Male, spontaneously hypertensive rats were subjected to transient middle cerebral artery occlusion. Expression profile of T-UCRs was determined at 3, 6, and 12 hours of reperfusion using microarrays and real-time polymerase chain reaction in the peri-infarct cortex. The putative functional significance of stroke responsive T-UCRs was identified by bioinformatics. RESULTS: Ischemia altered expression of 69 T-UCRs at >=1 time points of reperfusion compared with sham. Poststroke expression of the intragenic T-UCRs is independent of the expression of their parent gene mRNAs. Bioinformatics showed that the upstream/downstream and the parent genes of the T-UCRs modulate several biological and molecular functions, including metabolism, response to stimuli, cell communication, protein and nucleic acid binding. CONCLUSIONS: This first report shows that ischemic stroke temporally alters the noncoding ultraconserved RNAs in spontaneously hypertensive rats, but their functional significance is yet to be evaluated.

AB - Tissue adhesives are gaining popularity in ophthalmology, as they could potentially reduce the complications associated with current surgical methods. An ideal tissue adhesive should have superior tensile strength, be non-toxic and anti-inflammatory, improve efficiency and be cost-effective. Both synthetic and biological glues are available. The primary synthetic glues include cyanoacrylate and the recently introduced polyethylene glycol (PEG) derivatives, while most biological glues are composed of fibrin. Cyanoacrylate has a high tensile strength, but rapidly polymerises upon contact with any fluid and has been associated with histotoxicity. Fibrin induces less toxic and inflammatory reactions, and its polymerisation time can be controlled. Tensile strength studies have shown that fibrin is not as strong as cyanoacrylate. While more research is needed, PEG variants currently appear to have the most promise. These glues are non-toxic, strong and time-effective. Through MEDLINE and internet searches, this paper presents a systematic review of the current applications of surgical adhesives to corneal, glaucoma, retinal, cataract and strabismus surgeries. Our review suggests that surgical adhesives have promise to reduce problems in current ophthalmic surgical procedures. PMID- 29581353 TI - Optical coherence tomography angiography in comparison with other multimodal imaging techniques in punctate inner choroidopathy. AB - AIMS: To characterise punctate lesions and choroidal neovascularisation (CNV) in eyes with punctate inner choroidopathy (PIC) using current standard multimodal imaging techniques and optical coherence tomography angiography (OCTA). METHODS: In our prospective, single-centre study, 20 individuals with PIC underwent imaging with spectral-domain optical coherence tomography (SD-OCT), fluorescein angiography (FA), indocyanine green angiography, fundus autofluorescence, fundus colour photography and OCTA. RESULTS: Thirty-two eyes of 20 patients were affected. Eight (20%) eyes revealed typical punctate lesions, while 24 (60%) eyes had confirmed CNV on SD-OCT and FA in addition to punctate lesions. Of these 24 eyes with CNV, a reoccurrence of active CNV was detected in 5 (21%) eyes, a residual fluid in 3 (13%) eyes, while 16 (67%) eyes were defined as being stable. On OCTA, CNV was classified as having 'lacy wheel', 'pruned large-trunk' and 'dead tree aspect' vessel shapes with or without areas of non-perfusion. The disease activity was dependent on several predictors in the regression analysis such as intraretinal fluid (p=0.0014), CNV type (p=0.0199), leakage (p<0.0001) and hypoperfusion/non-perfusion (p<0.0001) on OCTA. CONCLUSION: OCTA offers additional valuable insight into the current standard multimodal imaging techniques used for characterisation of PIC. This imaging technique can be a useful tool for analysis of disease activity. PMID- 29581354 TI - Memory Follicular Helper Invariant NKT Cells Recognize Lipid Antigens on Memory B Cells and Elicit Antibody Recall Responses. AB - Invariant NKT (iNKT) cells have been shown to help B cells in a cognate or noncognate manner; however, whether cognate iNKT cell help induces B cell memory responses remains controversial, and the underlying mechanisms are still unclear. In this study, we demonstrated that, in the absence of follicular helper T cells, cognate iNKT cell help could promote B cell memory responses in mice that were dependent on the formation of memory follicular helper iNKT (iNKTFH) cells and their interactions with memory B cells in recall responses. Generation of memory iNKTFH cells required lipid Ag presentation by dendritic cells but not by B cells. Upon rechallenge, memory iNKTFH cells recognized lipid Ags presented by memory B cells, which recalled iNKTFH effector cells and elicited B cell memory responses. However, LPS, which promoted the synthesis of self-lipids, failed to elicit recall responses in the absence of exogenous lipid Ags. PMID- 29581355 TI - Filamin A Is Required for Optimal T Cell Integrin-Mediated Force Transmission, Flow Adhesion, and T Cell Trafficking. AB - T cells traffic from the bloodstream into tissues to perform their functions in the immune system and are therefore subjected to a range of different mechanical forces. Integrins are essential for T cell trafficking into the tissues, as they mediate firm adhesion between the T cell and the endothelium under shear flow conditions. In addition, integrins are important for the formation of the contact between the T cell and the APC required for T cell activation. The actin-binding protein filamin A (FlnA) provides an important link between the integrin and the actin cytoskeleton. FlnA has been reported to function as an integrin inhibitor by competing with talin. However, its role in regulating integrin-dependent immune functions in vivo is currently poorly understood. In this study, we have investigated the role of FlnA in T cells, using T cell-specific FlnA knockout mice. We report that FlnA is required for the formation of strong integrin-ligand bonds under shear flow and for the generation of integrin-mediated T cell traction forces on ligand-coated hydrogels. Consequently, absence of FlnA leads to a reduction in T cell adhesion to integrin ligands under conditions of shear flow, as well as reduced T cell trafficking into lymph nodes and sites of skin inflammation. In addition, FlnA is not needed for T cell activation in vivo, which occurs in shear-free conditions in lymphoid organs. Our results therefore reveal a role of FlnA in integrin force transmission and T cell trafficking in vivo. PMID- 29581356 TI - ICOS Signaling Controls Induction and Maintenance of Collagen-Induced Arthritis. AB - ICOS is a key costimulatory receptor facilitating differentiation and function of follicular helper T cells and inflammatory T cells. Rheumatoid arthritis patients were shown to have elevated levels of ICOS+ T cells in the synovial fluid, suggesting a potential role of ICOS-mediated T cell costimulation in autoimmune joint inflammation. In this study, using ICOS knockout and knockin mouse models, we found that ICOS signaling is required for the induction and maintenance of collagen-induced arthritis (CIA), a murine model of rheumatoid arthritis. For the initiation of CIA, the Tyr181-based SH2-binding motif of ICOS that is known to activate PI3K was critical for Ab production and expansion of inflammatory T cells. Furthermore, we found that Tyr181-dependent ICOS signaling is important for maintenance of CIA in an Ab-independent manner. Importantly, we found that a small molecule inhibitor of glycolysis, 3-bromopyruvate, ameliorates established CIA, suggesting an overlap between ICOS signaling, PI3K signaling, and glucose metabolism. Thus, we identified ICOS as a key costimulatory pathway that controls induction and maintenance of CIA and provide evidence that T cell glycolytic pathways can be potential therapeutic targets for rheumatoid arthritis.

Using Magt1-knockout mice (Magt1-/y ), we show that Mg2+ homeostasis was impaired in Magt1-/y B cells and Ca2+ influx was increased after BCR stimulation, whereas T and NK cell function was unaffected. Consequently, mutant B cells displayed an increased phosphorylation of BCR related proteins differentially affecting protein kinase C activation. These in vitro findings translated into increased frequencies of CD19+ B cells and marginal zone B cells and decreased frequencies of plasma cells among CD45+ splenocytes in vivo. Altogether, our study demonstrates for the first time, to our knowledge, that abolished MAGT1 function causes imbalanced cation homeostasis and developmental responses in B cells. Therefore, this study might contribute to a further understanding of B cell-related pathologies.

AB - Disturbed balance between immune surveillance and tolerance may lead to poor clinical outcomes in some malignancies. In paired analyses of adenocarcinoma and normal mucosa from 142 patients, we found a significant increase of the CD4/CD8 ratio and accumulation of regulatory T cells (Tregs) within the adenocarcinoma. The increased frequency of Tregs correlated with the local infiltration and extension of the tumor. There was concurrent maturation arrest, upregulation of programmed death-1 expression, and functional impairment in CD8+ T cells (CTLs) isolated from the adenocarcinoma. Adenocarcinoma-associated Tregs directly inhibit the function of normal human CTLs in vitro. With histopathological analysis, Foxp3+ Tregs were preferentially located in stroma. Concurrent transcriptome analysis of epithelial cells, stromal cells, and T cell subsets obtained from carcinomatous and normal intestinal samples from patients revealed a distinct gene expression signature in colorectal adenocarcinoma-associated Tregs, with overexpression of CCR1, CCR8, and TNFRSF9, whereas their ligands CCL4 and TNFSF9 were found upregulated in cancerous epithelium. Overexpression of WNT2 and CADM1, associated with carcinogenesis and metastasis, in cancer-associated stromal cells suggests that both cancer cells and stromal cells play important roles in the development and progression of colorectal cancer through the formation of a tumor microenvironment. The identification of CTL anergy by Tregs and the unique gene expression signature of human Tregs and stromal cells in colorectal cancer patients may facilitate the development of new therapeutics against malignancies.

AB - The prevalence of obesity has increased globally over the last 2 decades. Although the body mass index has been a convenient and simple index of obesity at the population level, studies have shown that obesity defined by body mass index alone is a remarkably heterogeneous condition with varying cardiovascular and metabolic manifestations across individuals. Adipose tissue is an exquisitely active metabolic organ engaged in cross-talk between various systems; perturbation of adipose tissue results in a pathological response to positive caloric balance in susceptible individuals that directly and indirectly contributes to cardiovascular and metabolic disease. Inadequate subcutaneous adipose tissue expansion in the face of dietary triglycerides leads to visceral and ectopic fat deposition, inflammatory/adipokine dysregulation, and insulin resistance. Conversely, preferential fat storage in the lower body depot may act as a metabolic buffer and protect other tissues from lipotoxicity caused by lipid overflow and ectopic fat. Translational, epidemiological, and clinical studies over the past 30 years have clearly demonstrated a strong link between visceral and ectopic fat and the development of a clinical syndrome characterized by atherogenic dyslipidemia, hyperinsulinemia/glucose intolerance, hypertension, atherosclerosis, and adverse cardiac remodeling/heart failure. This relationship is even more nuanced when clinical entities such as metabolically healthy obesity phenotype and the obesity paradox are considered. Although it is clear that the accumulation of visceral/ectopic fat is a major contributor to cardiovascular and metabolic risk above and beyond the body mass index, implementation of fat distribution assessment into clinical practice remains a challenge. Anthropometric indexes of obesity are easily implemented, but newer imaging-based methods offer improved sensitivity and specificity for measuring specific depots. Lifestyle, pharmacological, and surgical interventions allow a multidisciplinary approach to overweight/obesity that may improve outcomes and align with a public health message to combat the growing epidemic of obesity worldwide and to build healthier lives free of cardiovascular diseases.

Dysfunction in NMDA receptors has been implicated in neuropsychiatric diseases. While it is well recognized that the composition of NMDA receptors undergoes a GluN2B-to-GluN2A switch in early postnatal life, the mechanism regulating this switch remains unclear. Using transcriptomic and functional analyses in brain tissues from male and female Hipk2+/+ and Hipk2-/- mice, we showed that the HIPK2-JNK-c-Jun pathway is important in suppressing the transcription of Grin2a and Grin2c, which encodes the GluN2A and GluN2C subunits of the NMDA receptors, respectively. Loss of HIPK2 leads to a significant decrease in JNK-c-Jun signaling, which in turn derepresses the transcription of Grin2a and Grin2c mRNA and upregulates GluN2A and GluN2C protein levels. These changes result in a significant increase of GluN2A/GluN2B ratio in synapse and mitochondria, a persistent activation of the ERK-CREB pathway and the upregulation of synaptic activity-regulated genes, which collectively contribute to the resistance of Hipk2-/- neurons to cell death induced by mitochondrial toxins.SIGNIFICANCE STATEMENT We identify HIPK2-JNK-c Jun signaling as a key mechanism that regulates the transcription of NMDA receptor subunits GluN2A and GluN2C in vivo Our results provide insights into a previously unrecognized molecular mechanism that control the switch of NMDA receptor subunits in early postnatal brain development. Furthermore, we provide evidence that changes in the ratio of NMDA subunits GluN2A/GluN2B can also be detected in the synapse and mitochondria, which contributes to a persistent activation of the prosurvival ERK-CREB pathway and its downstream target genes. Collectively, these changes protect HIPK2 deficient neurons from mitochondrial toxins. PMID- 29581379 TI - Visual Mismatch and Predictive Coding: A Computational Single-Trial ERP Study. AB - Predictive coding (PC) posits that the brain uses a generative model to infer the environmental causes of its sensory data and uses precision-weighted prediction errors (pwPEs) to continuously update this model. While supported by much circumstantial evidence, experimental tests grounded in formal trial-by-trial predictions are rare. One partial exception is event-related potential (ERP) studies of the auditory mismatch negativity (MMN), where computational models have found signatures of pwPEs and related model-updating processes. Here, we tested this hypothesis in the visual domain, examining possible links between visual mismatch responses and pwPEs. We used a novel visual "roving standard" paradigm to elicit mismatch responses in humans (of both sexes) by unexpected changes in either color or emotional expression of faces. Using a hierarchical Bayesian model, we simulated pwPE trajectories of a Bayes-optimal observer and used these to conduct a comprehensive trial-by-trial analysis across the time * sensor space. We found significant modulation of brain activity by both color and emotion pwPEs. The scalp distribution and timing of these single-trial pwPE responses were in agreement with visual mismatch responses obtained by traditional averaging and subtraction (deviant-minus-standard) approaches. Finally, we compared the Bayesian model to a more classical change model of MMN. Model comparison revealed that trial-wise pwPEs explained the observed mismatch responses better than categorical change detection. Our results suggest that visual mismatch responses reflect trial-wise pwPEs, as postulated by PC. These findings go beyond classical ERP analyses of visual mismatch and illustrate the utility of computational analyses for studying automatic perceptual processes.SIGNIFICANCE STATEMENT Human perception is thought to rely on a predictive model of the environment that is updated via precision-weighted prediction errors (pwPEs) when events violate expectations. This "predictive coding" view is supported by studies of the auditory mismatch negativity brain potential. However, it is less well known whether visual perception of mismatch relies on similar processes. Here we combined computational modeling and electroencephalography to test whether visual mismatch responses reflected trial by-trial pwPEs. Applying a Bayesian model to series of face stimuli that violated expectations about color or emotional expression, we found significant modulation of brain activity by both color and emotion pwPEs. A categorical change detection model performed less convincingly. Our findings support the predictive coding interpretation of visual mismatch responses.

PMID- 29581380 TI - Effects of Aging on Cortical Neural Dynamics and Local Sleep Homeostasis in Mice. AB - Healthy aging is associated with marked effects on sleep, including its daily amount and architecture, as well as the specific EEG oscillations. Neither the neurophysiological underpinnings nor the biological significance of these changes are understood, and crucially the question remains whether aging is associated with reduced sleep need or a diminished capacity to generate sufficient sleep. Here we tested the hypothesis that aging may affect local cortical networks, disrupting the capacity to generate and sustain sleep oscillations, and with it the local homeostatic response to sleep loss. We performed chronic recordings of cortical neural activity and local field potentials from the motor cortex in young and older male C57BL/6J mice, during spontaneous waking and sleep, as well as during sleep after sleep deprivation. In older animals, we observed an increase in the incidence of non-rapid eye movement sleep local field potential slow waves and their associated neuronal silent (OFF) periods, whereas the overall pattern of state-dependent cortical neuronal firing was generally similar between ages. Furthermore, we observed that the response to sleep deprivation at the level of local cortical network activity was not affected by aging. Our data thus suggest that the local cortical neural dynamics and local sleep homeostatic mechanisms, at least in the motor cortex, are not impaired during healthy senescence in mice. This indicates that powerful protective or compensatory mechanisms may exist to maintain neuronal function stable across the life span, counteracting global changes in sleep amount and architecture.SIGNIFICANCE STATEMENT The biological significance of age-dependent changes in sleep is unknown but may reflect either a diminished sleep need or a reduced capacity to generate deep sleep stages. As aging has been linked to profound disruptions in cortical sleep oscillations and because sleep need is reflected in specific patterns of cortical activity, we performed chronic electrophysiological recordings of cortical neural activity during waking, sleep, and after sleep deprivation from young and older mice. We found that all main hallmarks of cortical activity during spontaneous sleep and recovery sleep after sleep deprivation were largely intact in older mice, suggesting that the well-described age-related changes in global sleep are unlikely to arise from a disruption of local network dynamics within the neocortex. PMID- 29581383 TI - High altitude arterialised capillary earlobe blood gas measurement using the Abbott i-STAT. AB - INTRODUCTION: Measurement of physiological parameters in extreme environments is essential to advancing knowledge, prophylaxis and treatment of altitude sickness. Point-of-care testing facilitates investigation in non-specialist and remote settings, as well as becoming increasingly popular at the bedside for real-time results in the clinical environment. Arterialised capillary earlobe blood gases are recommended as a valid alternative to arterial sampling in research. This study aimed to test the feasibility of obtaining and analysing daily earlobe samples at high altitude. METHODS: From 17 to 24 January 2016, 24 participants on a research expedition to Ecuador underwent daily earlobe blood gas measurements including pH, partial pressure of oxygen and partial pressure of carbon dioxide to 5043 m. Samples were analysed using an Abbott i-STAT blood gas analyser and G3+ cartridges. RESULTS: Daily measurements were successfully obtained and analysed at the point of care in 23/24 participants and were well tolerated with no adverse events. 12% (27/220) cartridges failed and required repeat sampling. CONCLUSIONS: Daily earlobe blood gas analysis using the Abbott i-STAT is feasible in a protected environment at high altitude. Participants and equipment should be kept warm before and during testing. Spare cartridges should be available. This methodology may be useful for both research and therapeutic measurements in remote, rural and wilderness medicine. PMID- 29581384 TI - Ultrasound is more reliable than inflammatory parameters to evaluate disease activity in patients with RA receiving tocilizumab therapy. AB - The target of treatment for rheumatoid arthritis (RA) is to keep low disease activity or remission. Tocilizumab can fully inhibit interleukin-6 and C reactive protein (CRP) production. The goal of the study is to search whether tocilizumab treatment compared with adalimumab treatment had the similar effect on sonography and inflammatory parameters in patients with RA. We compared ultrasound scores and inflammatory parameters between patients with RA receiving tocilizumab therapy and those receiving adalimumab therapy. Power Doppler (PD) ultrasound and grayscale synovial hypertrophy on bilateral radiocarpal joints were performed. Inflammatory mediators and ultrasound scores were compared by independent t-test between the adalimumab and tocilizumab groups. 65 patients with RA (32 tocilizumab and 33 adalimumab) were included. Between the two groups, there were no significant differences in age, gender, rheumatoid factors and anticyclic citrullinated peptide antibody. Following biological therapy, the ultrasound score was 2.33 in the tocilizumab group and 2.08 in the adalimumab group (p=0.570), while the erythrocyte sedimentation rate, CRP and Disease Activity Score in 28 joints (DAS28) were lower in the tocilizumab group. So ultrasound scores between the two groups were not significantly different, but the laboratory parameters and DAS28 were lower in the tocilizumab group than in the adalimumab group. Hence, to assess disease activity cannot be based only on clinical evaluations, so we suggest PD ultrasound to be used for all patients on tocilizumab therapy and reflect the true disease activity in these patients. PMID- 29581386 TI - Siglec expression on the surface of human, bull and ram sperm. AB - Sialic acid (Sia) is a major constituent of both the sperm glycocalyx and female reproductive mucosal surface and is involved in regulating sperm migration, uterotubal reservoir formation and oocyte binding. Siglecs (sialic acid-binding immunoglobulin - like lectins) commonly found on immune cells, bind to Sia in a linkage- and sugar-specific manner and often mediate cell-to-cell interactions and signalling. Proteomic and transcriptomic analysis of human and bovine sperm have listed Siglecs, but to date, their presence and/or localisation on sperm has not been studied. Therefore, the aim of this study was to characterise the presence of Siglecs on the surface of bovine, human and ovine sperm using both immunostaining and Western blotting. Siglec 1, 2, 5, 6, 10 and 14 were identified and displayed both species- and regional-specific expression on sperm. Almost universal expression across Siglecs and species was evident in the sperm neck and midpiece region while variable expression among Siglecs, similar among species, was detected in the head and tail regions of the sperm. The possible role for these proteins on sperm is discussed. PMID- 29581385 TI - Advanced body composition assessment: from body mass index to body composition profiling. AB - This paper gives a brief overview of common non-invasive techniques for body composition analysis and a more in-depth review of a body composition assessment method based on fat-referenced quantitative MRI. Earlier published studies of this method are summarized, and a previously unpublished validation study, based on 4753 subjects from the UK Biobank imaging cohort, comparing the quantitative MRI method with dual-energy X-ray absorptiometry (DXA) is presented. For whole body measurements of adipose tissue (AT) or fat and lean tissue (LT), DXA and quantitative MRIs show excellent agreement with linear correlation of 0.99 and 0.97, and coefficient of variation (CV) of 4.5 and 4.6 per cent for fat (computed from AT) and LT, respectively, but the agreement was found significantly lower for visceral adipose tissue, with a CV of >20 per cent. The additional ability of MRI to also measure muscle volumes, muscle AT infiltration and ectopic fat, in combination with rapid scanning protocols and efficient image analysis tools, makes quantitative MRI a powerful tool for advanced body composition assessment. PMID- 29581387 TI - RNASET2 impairs the sperm motility via PKA/PI3K/calcium signal pathways. AB - Asthenozoospermia is one of the leading causes of male infertility owing to a decline in sperm motility. Herein, we determined if there is a correlation between RNASET2 content on human spermatozoa and sperm motility in 205 semen samples from both asthenozoospermia patients and normozoospermia individuals. RNASET2 content was higher in sperm from asthenozoospermia patients than in normozoospermia individuals. On the other hand, its content was inversely correlated with sperm motility as well as progressive motility. Moreover, the inhibitory effect of RNASET2 on sperm motility was induced by incubating normozoospermic sperm with RNase T2 protein. Such treatment caused significant declines in intracellular spermatozoa PKA activity, PI3K activity and calcium level, which resulted in severely impaired sperm motility, and the sperm motility was largely rescued by cAMP supplementation. Finally, protein immunoprecipitation and mass spectrometry identified proteins whose interactions with RNASET2 were associated with declines in human spermatozoa motility. AKAP4, a protein regulating PKA activity, coimmunoprecipated with RNASET2 and they colocalized with one another in the sperm tail, which might contribute to reduced sperm motility. Thus, RNASET2 may be a novel biomarker of asthenozoospermia. Increases in RNASET2 can interact with AKAP4 in human sperm tail and subsequently reduce sperm motility by suppressing PKA/PI3K/calcium signaling pathways. PMID- 29581388 TI - Maternal inheritance of mitochondria: implications for male fertility? AB - Evolutionary theory predicts maternal inheritance of the mitochondria will lead to the accumulation of mutations in the mitochondrial DNA (mtDNA) that impair male fertility, but leave females unaffected. The hypothesis has been referred to as 'Mother's Curse'. There are many examples of mtDNA mutations or haplotypes, in humans and other metazoans, associated with decreases in sperm performance, but seemingly few reports of associations involving female reproductive traits; an observation that has been used to support the Mother's Curse hypothesis. However, it is unclear whether apparent signatures of male bias in mitochondrial genetic effects on fertility reflect an underlying biological bias or a technical bias resulting from a lack of studies to have screened for female effects. Here, we conduct a systematic literature search of studies reporting mitochondrial genetic effects on fertility-related traits in gonochoristic metazoans (animals with two distinct sexes). Studies of female reproductive outcomes were sparse, reflecting a large technical sex bias across the literature. We were only able to make a valid assessment of sex specificity of mitochondrial genetic effects in 30% of cases. However, in most of these cases, the effects were male biased, including examples of male bias associated with mtDNA mutations in humans. These results are therefore consistent with the hypothesis that maternal inheritance has enriched mtDNA sequences with mutations that specifically impair male fertility. However, future research that redresses the technical imbalance in studies conducted per sex will be key to enabling researchers to fully assess the wider implications of the Mother's Curse hypothesis to male reproductive biology. PMID- 29581389 TI - Collective movement in ecology: from emerging technologies to conservation and management. AB - Recent advances in technology and quantitative methods have led to the emergence of a new field of study that stands to link insights of researchers from two closely related, but often disconnected disciplines: movement ecology and collective animal behaviour. To date, the field of movement ecology has focused on elucidating the internal and external drivers of animal movement and the influence of movement on broader ecological processes. Typically, tracking and/or remote sensing technology is employed to study individual animals in natural conditions. By contrast, the field of collective behaviour has quantified the significant role social interactions play in the decision-making of animals within groups and, to date, has predominantly relied on controlled laboratory based studies and theoretical models owing to the constraints of studying interacting animals in the field. This themed issue is intended to formalize the burgeoning field of collective movement ecology which integrates research from both movement ecology and collective behaviour. In this introductory paper, we set the stage for the issue by briefly examining the approaches and current status of research in these areas. Next, we outline the structure of the theme issue and describe the obstacles collective movement researchers face, from data acquisition in the field to analysis and problems of scale, and highlight the key contributions of the assembled papers. We finish by presenting research that links individual and broad-scale ecological and evolutionary processes to collective movement, and finally relate these concepts to emerging challenges for the management and conservation of animals on the move in a world that is increasingly impacted by human activity.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581390 TI - Challenges and solutions for studying collective animal behaviour in the wild. AB - Mobile animal groups provide some of the most compelling examples of self organization in the natural world. While field observations of songbird flocks wheeling in the sky or anchovy schools fleeing from predators have inspired considerable interest in the mechanics of collective motion, the challenge of simultaneously monitoring multiple animals in the field has historically limited our capacity to study collective behaviour of wild animal groups with precision. However, recent technological advancements now present exciting opportunities to overcome many of these limitations. Here we review existing methods used to collect data on the movements and interactions of multiple animals in a natural setting. We then survey emerging technologies that are poised to revolutionize the study of collective animal behaviour by extending the spatial and temporal scales of inquiry, increasing data volume and quality, and expediting the post processing of raw data.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581391 TI - Inferring influence and leadership in moving animal groups. AB - Collective decision-making is a daily occurrence in the lives of many group living animals, and can have critical consequences for the fitness of individuals. Understanding how decisions are reached, including who has influence and the mechanisms by which information and preferences are integrated, has posed a fundamental challenge. Here, we provide a methodological framework for studying influence and leadership in groups. We propose that individuals have influence if their actions result in some behavioural change among their group-mates, and are leaders if they consistently influence others. We highlight three components of influence (influence instances, total influence and consistency of influence), which can be assessed at two levels (individual-to-individual and individual-to group). We then review different methods, ranging from individual positioning within groups to information-theoretic approaches, by which influence has been operationally defined in empirical studies, as well as how such observations can be aggregated to give insight into the underlying decision-making process. We focus on the domain of collective movement, with a particular emphasis on methods that have recently been, or are being, developed to take advantage of simultaneous tracking data. We aim to provide a resource bringing together methodological tools currently available for studying leadership in moving animal groups, as well as to discuss the limitations of current methodologies and suggest productive avenues for future research.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581392 TI - Disentangling social interactions and environmental drivers in multi-individual wildlife tracking data. AB - While many animal species exhibit strong conspecific interactions, movement analyses of wildlife tracking datasets still largely focus on single individuals. Multi-individual wildlife tracking studies provide new opportunities to explore how individuals move relative to one another, but such datasets are frequently too sparse for the detailed, acceleration-based analytical methods typically employed in collective motion studies. Here, we address the methodological gap between wildlife tracking data and collective motion by developing a general method for quantifying movement correlation from sparsely sampled data. Unlike most existing techniques for studying the non-independence of individual movements with wildlife tracking data, our approach is derived from an analytically tractable stochastic model of correlated movement. Our approach partitions correlation into a deterministic tendency to move in the same direction termed 'drift correlation' and a stochastic component called 'diffusive correlation'. These components suggest the mechanisms that coordinate movements, with drift correlation indicating external influences, and diffusive correlation pointing to social interactions. We use two case studies to highlight the ability of our approach both to quantify correlated movements in tracking data and to suggest the mechanisms that generate the correlation. First, we use an abrupt change in movement correlation to pinpoint the onset of spring migration in barren-ground caribou. Second, we show how spatial proximity mediates intermittently correlated movements among khulans in the Gobi desert. We conclude by discussing the linkages of our approach to the theory of collective motion.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581393 TI - The importance of individual variation in the dynamics of animal collective movements. AB - Animal collective movements are a key example of a system that links two clearly defined levels of organization: the individual and the group. Most models investigating collective movements have generated coherent collective behaviours without the inclusion of individual variability. However, new individual-based models, together with emerging empirical information, emphasize that within-group heterogeneity may strongly influence collective movement behaviour. Here we (i) review the empirical evidence for individual variation in animal collective movements, (ii) explore how theoretical investigations have represented individual heterogeneity when modelling collective movements and (iii) present a model to show how within-group heterogeneity influences the collective properties of a group. Our review underscores the need to consider variability at the level of the individual to improve our understanding of how individual decision rules lead to emergent movement patterns, and also to yield better quantitative predictions of collective behaviour.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581395 TI - Different bees, different needs: how nest-site requirements have shaped the decision-making processes in homeless honeybees (Apis spp.). AB - During reproductive swarming, a honeybee swarm needs to decide on a new nest site and then move to the chosen site collectively. Most studies of swarming and nest site selection are based on one species, Apis mellifera Natural colonies of A. mellifera live in tree cavities. The quality of the cavity is critical to the survival of a swarm. Other honeybee species nest in the open, and have less strict nest-site requirements, such as the open-nesting dwarf honeybee Apis floreaApis florea builds a nest comprised of a single comb suspended from a twig. For a cavity-nesting species, there is only a limited number of potential nest sites that can be located by a swarm, because suitable sites are scarce. By contrast, for an open-nesting species, there is an abundance of equally suitable twigs. While the decision-making process of cavity-nesting bees is geared towards selecting the best site possible, open-nesting species need to coordinate collective movement towards areas with potential nest sites. Here, we argue that the nest-site selection processes of A. florea and A. mellifera have been shaped by each species' specific nest-site requirements. Both species use the same behavioural algorithm, tuned to allow each species to solve their species specific problem.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581394 TI - Collective animal navigation and migratory culture: from theoretical models to empirical evidence. AB - Animals often travel in groups, and their navigational decisions can be influenced by social interactions. Both theory and empirical observations suggest that such collective navigation can result in individuals improving their ability to find their way and could be one of the key benefits of sociality for these species. Here, we provide an overview of the potential mechanisms underlying collective navigation, review the known, and supposed, empirical evidence for such behaviour and highlight interesting directions for future research. We further explore how both social and collective learning during group navigation could lead to the accumulation of knowledge at the population level, resulting in the emergence of migratory culture.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581396 TI - Synchronization, coordination and collective sensing during thermalling flight of freely migrating white storks. AB - Exploring how flocks of soaring migrants manage to achieve and maintain coordination while exploiting thermal updrafts is important for understanding how collective movements can enhance the sensing of the surrounding environment. Here we examined the structural organization of a group of circling white storks (Ciconia ciconia) throughout their migratory journey from Germany to Spain. We analysed individual high-resolution GPS trajectories of storks during circling events, and evaluated each bird's flight behaviour in relation to its flock members. Within the flock, we identified subgroups that synchronize their movements and coordinate switches in their circling direction within thermals. These switches in direction can be initiated by any individual of the subgroup, irrespective of how advanced its relative vertical position is, and occur at specific horizontal locations within the thermal allowing the storks to remain within the thermal. Using the motion of all flock members, we were able to examine the dynamic variation of airflow within the thermals and to determine the specific environmental conditions surrounding the flock. With an increasing amount of high-resolution GPS tracking, we may soon be able to use these animals as distributed sensors providing us with a new means to obtain a detailed knowledge of our environment.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581397 TI - From single steps to mass migration: the problem of scale in the movement ecology of the Serengeti wildebeest. AB - A central question in ecology is how to link processes that occur over different scales. The daily interactions of individual organisms ultimately determine community dynamics, population fluctuations and the functioning of entire ecosystems. Observations of these multiscale ecological processes are constrained by various technological, biological or logistical issues, and there are often vast discrepancies between the scale at which observation is possible and the scale of the question of interest. Animal movement is characterized by processes that act over multiple spatial and temporal scales. Second-by-second decisions accumulate to produce annual movement patterns. Individuals influence, and are influenced by, collective movement decisions, which then govern the spatial distribution of populations and the connectivity of meta-populations. While the field of movement ecology is experiencing unprecedented growth in the availability of movement data, there remain challenges in integrating observations with questions of ecological interest. In this article, we present the major challenges of addressing these issues within the context of the Serengeti wildebeest migration, a keystone ecological phenomena that crosses multiple scales of space, time and biological complexity.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581398 TI - Fitness trade-offs of group formation and movement by Thomson's gazelles in the Serengeti ecosystem. AB - Collective behaviours contributing to patterns of group formation and coordinated movement are common across many ecosystems and taxa. Their ubiquity is presumably due to altering interactions between individuals and their predators, resources and physical environment in ways that enhance individual fitness. On the other hand, fitness costs are also often associated with group formation. Modifications to these interactions have the potential to dramatically impact population-level processes, such as trophic interactions or patterns of space use in relation to abiotic environmental variation. In a wide variety of empirical systems and models, collective behaviour has been shown to enhance access to ephemeral patches of resources, reduce the risk of predation and reduce vulnerability to environmental fluctuation. Evolution of collective behaviour should accordingly depend on the advantages of collective behaviour weighed against the costs experienced at the individual level. As an illustrative case study, we consider the potential trade-offs on Malthusian fitness associated with patterns of group formation and movement by migratory Thomson's gazelles in the Serengeti ecosystem.This article is part of the theme issue 'Collective movement ecology'.

Heterospecific sociality, although documented in numerous taxa and contexts, remains at the margins of sociality research and is rarely investigated in conjunction with single-species sociality. This could be because heterospecific and single-species sociality are thought to be based on fundamentally different mechanisms. However, our literature survey shows that heterospecific sociality based on mechanisms similar to single-species sociality is reported from many taxa, contexts and for various benefits. Therefore, we propose a conceptual framework to understand conspecific versus heterospecific social partner choice. Previous attempts, which are all in the context of social information, model partner choice as a trade-off between information benefit and competition cost, along a single phenotypic distance axis. Our framework of partner choice considers both direct grouping benefits and information benefits, allows heterospecific and conspecific partners to differ in degree and qualitatively, and uses a multi-dimensional trait space analysis of costs (competition and activity matching) and benefits (relevance of partner and quality of partner). We conclude that social partner choice is best-viewed as a continuum: some social benefits are obtainable only from conspecifics, some only from dissimilar heterospecifics, while many are potentially obtainable from conspecifics and heterospecifics.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581400 TI - Using activity and sociability to characterize collective motion. AB - A wide range of measurements can be made on the collective motion of groups, and the movement of individuals within them. These include, but are not limited to: group size, polarization, speed, turning speed, speed or directional correlations, and distances to near neighbours. From an ecological and evolutionary perspective, we would like to know which of these measurements capture biologically meaningful aspects of an animal's behaviour and contribute to its survival chances. Previous simulation studies have emphasized two main factors shaping individuals' behaviour in groups; attraction and alignment. Alignment responses appear to be important in transferring information between group members and providing synergistic benefits to group members. Likewise, attraction to conspecifics is thought to provide benefits through, for example, selfish herding. Here, we use a factor analysis on a wide range of simple measurements to identify two main axes of collective motion in guppies (Poecilia reticulata): (i) sociability, which corresponds to attraction (and to a lesser degree alignment) to neighbours, and (ii) activity, which combines alignment with directed movement. We show that for guppies, predation in a natural environment produces higher degrees of sociability and (in females) lower degrees of activity, while female guppies sorted for higher degrees of collective alignment have higher degrees of both sociability and activity. We suggest that the activity and sociability axes provide a useful framework for measuring the behaviour of animals in groups, allowing the comparison of individual and collective behaviours within and between species.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581401 TI - Migration in the Anthropocene: how collective navigation, environmental system and taxonomy shape the vulnerability of migratory species. AB - Recent increases in human disturbance pose significant threats to migratory species using collective movement strategies. Key threats to migrants may differ depending on behavioural traits (e.g. collective navigation), taxonomy and the environmental system (i.e. freshwater, marine or terrestrial) associated with migration. We quantitatively assess how collective navigation, taxonomic membership and environmental system impact species' vulnerability by (i) evaluating population change in migratory and non-migratory bird, mammal and fish species using the Living Planet Database (LPD), (ii) analysing the role of collective navigation and environmental system on migrant extinction risk using International Union for Conservation of Nature (IUCN) classifications and (iii) compiling literature on geographical range change of migratory species. Likelihood of population decrease differed by taxonomic group: migratory birds were more likely to experience annual declines than non-migrants, while mammals displayed the opposite pattern. Within migratory species in IUCN, we observed that collective navigation and environmental system were important predictors of extinction risk for fishes and birds, but not for mammals, which had overall higher extinction risk than other taxa. We found high phylogenetic relatedness among collectively navigating species, which could have obscured its importance in determining extinction risk. Overall, outputs from these analyses can help guide strategic interventions to conserve the most vulnerable migrations.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581402 TI - Eco-evolutionary dynamics, density-dependent dispersal and collective behaviour: implications for salmon metapopulation robustness. AB - The spatial dispersal of individuals plays an important role in the dynamics of populations, and is central to metapopulation theory. Dispersal provides connections within metapopulations, promoting demographic and evolutionary rescue, but may also introduce maladapted individuals, potentially lowering the fitness of recipient populations through introgression of heritable traits. To explore this dual nature of dispersal, we modify a well-established eco evolutionary model of two locally adapted populations and their associated mean trait values, to examine recruiting salmon populations that are connected by density-dependent dispersal, consistent with collective migratory behaviour that promotes navigation. When the strength of collective behaviour is weak such that straying is effectively constant, we show that a low level of straying is associated with the highest gains in metapopulation robustness and that high straying serves to erode robustness. Moreover, we find that as the strength of collective behaviour increases, metapopulation robustness is enhanced, but this relationship depends on the rate at which individuals stray. Specifically, strong collective behaviour increases the presence of hidden low-density basins of attraction, which may serve to trap disturbed populations, and this is exacerbated by increased habitat heterogeneity. Taken as a whole, our findings suggest that density-dependent straying and collective migratory behaviour may help metapopulations, such as in salmon, thrive in dynamic landscapes. Given the pervasive eco-evolutionary impacts of dispersal on metapopulations, these findings have important ramifications for the conservation of salmon metapopulations facing both natural and anthropogenic contemporary disturbances.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581403 TI - Personality and the collective: bold homing pigeons occupy higher leadership ranks in flocks. AB - While collective movement is ecologically widespread and conveys numerous benefits on individuals, it also poses a coordination problem: who controls the group's movements? The role that animal 'personalities' play in this question has recently become a focus of research interest. Although many animal groups have distributed leadership (i.e. multiple individuals influence collective decisions), studies linking personality and leadership have focused predominantly on the group's single most influential individual. In this study, we investigate the relationship between personality and the influence of multiple leaders on collective movement using homing pigeons, Columba livia, a species known to display complex multilevel leadership hierarchies during flock flights. Our results show that more exploratory (i.e. 'bold') birds are more likely to occupy higher ranks in the leadership hierarchy and thus have more influence on the direction of collective movement than less exploratory (i.e. 'shy') birds during both free flights around their lofts and homing flights from a distant site. Our data also show that bold pigeons fly faster than shy birds during solo flights. We discuss our results in light of theories about the evolution of personality, with specific reference to the adaptive value of heterogeneity in animal groups.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581404 TI - Inferring the rules of social interaction in migrating caribou. AB - Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to environmental cues, and the cultural transmission of optimal routes. Despite their significance, the precise nature of social interactions in migrating species remains largely unknown. Here we deploy unmanned aerial systems to collect aerial footage of caribou as they undertake their migration from Victoria Island to mainland Canada. Through a Bayesian analysis of trajectories we reveal the fine-scale interaction rules of migrating caribou and show they are attracted to one another and copy directional choices of neighbours, but do not interact through clearly defined metric or topological interaction ranges. By explicitly considering the role of social information on movement decisions we construct a map of near neighbour influence that quantifies the nature of information flow in these herds. These results will inform more realistic, mechanism-based models of migration in caribou and other social ungulates, leading to better predictions of spatial use patterns and responses to changing environmental conditions. Moreover, we anticipate that the protocol we developed here will be broadly applicable to study social behaviour in a wide range of migratory and non-migratory taxa.This article is part of the theme issue 'Collective movement ecology'. PMID- 29581405 TI - Lung abscess or empyema? Taking a closer look. PMID- 29581406 TI - Staphylococcus aureus utilizes host-derived lipoprotein particles as sources of exogenous fatty acids. AB - Methicillin-resistant Staphylococcus aureus (MRSA) is a threat to global health. Consequently, much effort has focused on the development of new antimicrobials that target novel aspects of S. aureus physiology. Fatty acids are required to maintain cell viability, and bacteria synthesize fatty acids using the type II fatty acid synthesis pathway (FASII). FASII is significantly different from human fatty acid synthesis, underscoring the therapeutic potential of inhibiting this pathway. However, many Gram-positive pathogens incorporate exogenous fatty acids, bypassing FASII inhibition and leaving the clinical potential of FASII inhibitors uncertain. Importantly, the source(s) of fatty acids available to pathogens within the host environment remains unclear. Fatty acids are transported throughout the body by lipoprotein particles in the form of triglycerides and esterified cholesterol. Thus, lipoproteins, such as low-density lipoprotein (LDL) represent a potentially rich source of exogenous fatty acids for S. aureus during infection. We sought to test the ability of LDLs to serve as a fatty acid source for S. aureus and show that cells cultured in the presence of human LDLs demonstrate increased tolerance to the FASII inhibitor, triclosan. Using mass spectrometry, we observed that host-derived fatty acids present in the LDLs are incorporated into the staphylococcal membrane and that tolerance to triclosan is facilitated by the fatty acid kinase A, FakA, and Geh, a triacylglycerol lipase. Finally, we demonstrate that human LDLs support the growth of S. aureus fatty acid auxotrophs. Together, these results suggest that human lipoprotein particles are a viable source of exogenous fatty acids for S. aureus during infection.IMPORTANCE Inhibition of bacterial fatty acid synthesis is a promising approach to combating infections caused by S. aureus and other human pathogens. However, S. aureus incorporates exogenous fatty acids into its phospholipid bilayer. Therefore, the clinical utility of targeting bacterial fatty acid synthesis is debated. Moreover, the fatty acid reservoir(s) exploited by S. aureus are not well understood. Human low-density lipoprotein particles represent a particularly abundant in vivo source of fatty acids and are present in tissues S. aureus colonizes. Herein, we establish that S. aureus is capable of utilizing the fatty acids present in low-density lipoproteins to bypass both chemical and genetic inhibition of fatty acid synthesis. These findings imply that S. aureus targets LDLs as a source of fatty acids during pathogenesis. PMID- 29581407 TI - A Critical Region in the FlaA Flagellin Facilitates Filament Formation of the Vibrio cholerae Flagellum. AB - Vibrio cholerae is a Gram-negative bacterium with a monotrichous flagellum that causes the human disease cholera. Flagellum-mediated motility is an integral part of the bacterial life cycle inside the host and in the aquatic environment. The V. cholerae flagellar filament is composed of five flagellin subunits (FlaA, FlaB, FlaC, FlaD, and FlaE); however, only FlaA is necessary and sufficient for filament synthesis. flaA is transcribed from a class III flagellar promoter, whereas the other four flagellins are transcribed from class IV promoters. However, expressing flaA from a class IV promoter still facilitated motility in a strain that was otherwise lacking all five flagellins (DeltaflaA-E). Furthermore, FlaA from V. parahaemolyticus (FlaAVP; 77% identity) supported motility of the V. cholerae DeltaflaA-E strain, whereas FlaA from V. vulnificus (FlaAVV; 75% identity) did not, indicating that FlaA amino acid sequence is responsible for its critical role in flagellar synthesis. Chimeric proteins composed of different domains of FlaAVC and FlaD or FlaAVV revealed that the N-terminal D1 domain (D1N) contains an important region required for FlaA function. Further analyses of chimeric FlaAVC-FlaD proteins identified a lysine residue present at position 145 of the other flagellins but absent from FlaAVC that can prevent monofilament formation. Moreover, the D1N region of amino acids 87 to 153 of FlaAVV inserted into FlaAVC allows monofilament formation but not motility, apparently due to the lack of filament curvature. These results identify residues within the D1N domain that allow FlaAVC to fold into a functional filament structure and suggest that FlaAVC assists correct folding of the other flagellins.IMPORTANCEV. cholerae causes the severe diarrheal disease cholera. Its ability to swim is mediated by rotation of a polar flagellum, and this motility is integral to its ability to cause disease and persist in the environment. The current studies illuminate how one specific flagellin (FlaA) within a multiflagellin structure mediates formation of the flagellar filament, thus allowing V. cholerae to swim. This knowledge can lead to safer vaccines and potential therapeutics to inhibit cholera. PMID- 29581409 TI - One Intact Transmembrane Substrate Binding Site Is Sufficient for the Function of the Homodimeric Type I ATP-Binding Cassette Importer for Positively Charged Amino Acids Art(MP)2 of Geobacillus stearothermophilus. AB - ATP-binding cassette (ABC) transport systems comprise two transmembrane domains/subunits that form a translocation path and two nucleotide-binding domains/subunits that bind and hydrolyze ATP. Prokaryotic canonical ABC import systems require an extracellular substrate-binding protein for function. Knowledge of substrate-binding sites within the transmembrane subunits is scarce. Recent crystal structures of the ABC importer Art(QN)2 for positively charged amino acids of Thermoanerobacter tengcongensis revealed the presence of one substrate molecule in a defined binding pocket in each of the transmembrane subunits, ArtQ (J. Yu, J. Ge, J. Heuveling, E. Schneider, and M. Yang, Proc Natl Acad Sci U S A 112:5243-5248, 2015, https://doi.org/10.1073/pnas.1415037112). This finding raised the question of whether both sites must be loaded with substrate prior to initiation of the transport cycle. To address this matter, we first explored the role of key residues that form the binding pocket in the closely related Art(MP)2 transporter of Geobacillus stearothermophilus, by monitoring consequences of mutations in ArtM on ATPase and transport activity at the level of purified proteins embedded in liposomes. Our results emphasize that two negatively charged residues (E153 and D160) are crucial for wild-type function. Furthermore, the variant Art[M(L67D)P]2 exhibited strongly impaired activities, which is why it was considered for construction of a hybrid complex containing one intact and one impaired substrate-binding site. Activity assays clearly revealed that one intact binding site was sufficient for function. To our knowledge, our study provides the first biochemical evidence on transmembrane substrate-binding sites of an ABC importer.IMPORTANCE Canonical prokaryotic ATP binding cassette importers mediate the uptake of a large variety of chemicals, including nutrients, osmoprotectants, growth factors, and trace elements. Some also play a role in bacterial pathogenesis, which is why full understanding of their mode of action is of the utmost importance. One of the unsolved problems refers to the chemical nature and number of substrate binding sites formed by the transmembrane subunits. Here, we report that a hybrid amino acid transporter of G. stearothermophilus, encompassing one intact and one impaired transmembrane binding site, is fully competent in transport, suggesting that the binding of one substrate molecule is sufficient to trigger the translocation process. PMID- 29581408 TI - The Opp (AmiACDEF) Oligopeptide Transporter Mediates Resistance of Serotype 2 Streptococcus pneumoniae D39 to Killing by Chemokine CXCL10 and Other Antimicrobial Peptides. AB - Antimicrobial peptides (AMPs), including chemokines, are produced during infections to kill pathogenic bacteria. To fill in gaps in knowledge about the sensitivities of Streptococcus pneumoniae and related Streptococcus species to chemokines and AMPs, we performed a systematic, quantitative study of inhibition by chemokine CXCL10 and the AMPs LL-37 and nisin. In a standard Tris-glucose buffer (TGS), all strains assayed lacked metabolic activity, as determined by resazurin (alamarBlue) reduction, and were extremely sensitive to CXCL10 and AMPs (50% inhibitory concentration [IC50], ~0.04 MUM). In TGS, changes in sensitivities caused by mutations were undetectable. In contrast, strains that retained reductive metabolic activity in a different assay buffer (NPB [10 mM sodium phosphate {pH 7.4}, 1% {vol/vol} brain heart infusion {BHI} broth]) were less sensitive to CXCL10 and AMPs than in TGS. In NPB, mutants known to respond to AMPs, such as Deltadlt mutants lacking d-alanylation of teichoic acids, exhibited the expected increased sensitivity. S. pneumoniae serotype 2 strain D39 was much (~10-fold) less sensitive to CXCL10 killing in NPB than serotype 4 strain TIGR4, and the sensitivity of TIGR4 was unaffected by the absence of capsule. Candidate screening of strain D39 revealed that mutants lacking Opp (DeltaamiACDEF) oligopeptide permease were significantly more resistant to CXCL10 than the wild-type strain. This increased resistance could indicate that Opp is a target for CXCL10 binding or that it transports CXCL10 into cells. Finally, DeltaftsX or DeltaftsE mutants of Bacillus subtilis or amino acid changes that interfere with FtsX function in S. pneumoniae did not impart resistance to CXCL10, in contrast to previous results for Bacillus anthracis, indicating that FtsX is not a general target for CXCL10 binding.IMPORTANCES. pneumoniae (pneumococcus) is a human commensal bacterium and major opportunistic respiratory pathogen that causes serious invasive diseases, killing millions of people worldwide annually. Because of its increasing antibiotic resistance, S. pneumoniae is now listed as a "superbug" for which new antibiotics are urgently needed. This report fills in knowledge gaps and resolves inconsistencies in the scientific literature about the sensitivity of S. pneumoniae and related Streptococcus pathogens to chemokines and AMPs. It also reveals a new mechanism by which S. pneumoniae can acquire resistance to chemokine CXCL10. This mechanism involves the Opp (AmiACDEF) oligopeptide transporter, which plays additional pleiotropic roles in pneumococcal physiology, quorum sensing, and virulence. Taking the results together, this work provides new information about the way chemokines kill pneumococcal cells. PMID- 29581410 TI - Environmental role of pathogenic traits in Vibrio cholerae. AB - Vibrio cholerae is a natural inhabitant of aquatic ecosystems. Some strains of V. cholerae can colonize the human host and cause cholera, a profuse watery diarrhea. The major pathogenicity factors and virulence regulators of V. cholerae are either encoded in mobile genetic elements acquired in the environment (e.g. pathogenicity islands or lysogenic phages) or in the core genome. Several lines of evidence indicate that the emergence of numerous virulence traits of V. cholerae occurred in its natural environment due to biotic and abiotic pressures. Here, we discuss the connection between the human host and the potential ecological role of these virulent traits. Unraveling these connections will help us understand the emergence of this organism and other facultative bacterial pathogens. PMID- 29581413 TI - Visible-light promoted catalytic activity of dumbbell-like Au nanorods supported on graphene/TiO2 sheets towards hydrogenation reaction. AB - In this work, the rationally-designed sharp corners on Au nanorods tremendously improved the catalytic activity, particularly in the presence of visible light irradiation, towards the hydrogenation of 4-nitrophenol to 4-aminophenol. A strikingly increased rate constant of 50.6 g-1 s-1 L was achieved in M-Au-3, which was 41.8 times higher than that of parent Au nanorods under dark conditions. The enhanced activities were proportional to the extent of the protruding sharp corners. Furthermore, remarkably enhanced activities were achieved in novel ternary Au/RGO/TiO2 sheets, which were endowed with a 52.0 times higher rate constant than that of straight Au nanorods. These remarkably enhanced activities were even higher than those of previously reported 3-5 nm Au and 3 nm Pt nanoparticles. It was systematically observed that there are three aspects to the synergistic effects between Au and RGO sheets: (i) electron transfer from RGO to Au, (ii) a high concentration of p-nitrophenol close to dumbbell-like Au nanorods on RGO sheets, and (iii) increased local reaction temperature from the photothermal effect of both dumbbell-like Au nanorods and RGO sheets. PMID- 29581411 TI - The Transcriptional Regulator BpsR Controls the Growth of Bordetella bronchiseptica by Repressing Genes Involved in Nicotinic Acid Degradation. AB - Many of the pathogenic species of the genus Bordetella have an absolute requirement for nicotinic acid (NA) for laboratory growth. These Gram-negative bacteria also harbor a gene cluster homologous to the nic cluster of Pseudomonas putida which is involved in the aerobic degradation of NA and its transcriptional control. We report here that BpsR, a negative regulator of biofilm formation and Bps polysaccharide production, controls the growth of Bordetella bronchiseptica by repressing the expression of nic genes. The severe growth defect of the DeltabpsR strain in Stainer-Scholte medium was restored by supplementation with NA, which also functioned as an inducer of nic genes at low micromolar concentrations that are usually present in animals and humans. Purified BpsR protein bound to the nic promoter region, and its DNA binding activity was inhibited by 6-hydroxynicotinic acid (6-HNA), the first metabolite of the NA degradative pathway. Reporter assays with the isogenic mutant derivative of the wild-type (WT) strain harboring deletion in nicA, which encodes a putative nicotinic acid hydroxylase responsible for conversion of NA to 6-HNA, showed that 6-HNA is the actual inducer of the nic genes in the bacterial cell. Gene expression profiling further showed that BpsR dually activated and repressed the expression of genes associated with pathogenesis, transcriptional regulation, metabolism, and other cellular processes. We discuss the implications of these findings with respect to the selection of pyridines such as NA and quinolinic acid for optimum bacterial growth depending on the ecological niche.IMPORTANCE BpsR, the previously described regulator of biofilm formation and Bps polysaccharide production, controls Bordetella bronchiseptica growth by regulating the expression of genes involved in the degradation of nicotinic acid (NA). 6-Hydroxynicotinic acid (6-HNA), the first metabolite of the NA degradation pathway prevented BpsR from binding to DNA and was the actual in vivo inducer. We hypothesize that BpsR enables Bordetella bacteria to efficiently and selectively utilize NA for their survival depending on the environment in which they reside. The results reported herein lay the foundation for future investigations of how BpsR and the alteration of its activity by NA orchestrate the control of Bordetella growth, metabolism, biofilm formation, and pathogenesis. PMID- 29581412 TI - HnRNP L represses cryptic exons. AB - The fidelity of RNA splicing is regulated by a network of splicing enhancers and repressors, although the rules that govern this process are not yet fully understood. One mechanism that contributes to splicing fidelity is the repression of nonconserved cryptic exons by splicing factors that recognize dinucleotide repeats. We previously identified that TDP-43 and PTBP1/PTBP2 are capable of repressing cryptic exons utilizing UG and CU repeats, respectively. Here we demonstrate that hnRNP L (HNRNPL) also represses cryptic exons by utilizing exonic CA repeats, particularly near the 5'SS. We hypothesize that hnRNP L regulates CA repeat repression for both cryptic exon repression and developmental processes such as T cell differentiation.

PMID- 29581414 TI - Nephrectomy Versus Embolization of Non-Functioning Renal Graft: A Systematic Review with a Proportional Meta-Analysis. AB - There is no standardization on the timing of the best approach to treat a non functioning renal graft. We reviewed the literature and performed a proportional meta-analysis of case series of transplantectomy and embolization for a non functioning renal graft. The groups were compared for mortality and morbidity outcomes. A total of 2421 patients were included in this review. Of these, 2232 patients underwent transplantectomy and 189 underwent percutaneous embolization. The mortality rate in the nephrectomy group was 4% [95% confidence interval [CI], 2-7%; I2=87%] as compared with 0.1% [95% CI, 0.1-0.5%; I2=0%] in the embolization group. The rates of common morbidities were 18% [95% CI, 13-26%, I2=79.7%] for nephrectomy compared with 1.2% [95% CI, 0.7-2.1%, I2=26.4%] for embolization. The incidence of post-embolization syndrome was 68%, and 20% of patients needed post embolization nephrectomy. Percutaneous embolization was associated with lower mortality and morbidity rates but also with a high rate of post-embolization syndrome. However, in most cases this complication had easily manageable symptoms. Embolization is a new and attractive technique that can be considered in treating non-functioning renal grafts.

AB - BACKGROUND Enterocolitis is an immune-related adverse event associated with nivolumab treatment. Although intravenous corticosteroids and infliximab are recommended as a first-line and second-line therapy, respectively, there is no established treatment for severe enterocolitis that is refractory to these drugs. CASE REPORT A 62-year-old male with non-small cell lung cancer, with multiple brain metastasis, received nivolumab as the eighth-line chemotherapy for his disease. A few days after nivolumab administration, grade 2-3 enterocolitis developed in the patient. The enterocolitis improved to grade 1 after careful observation; however, it was aggravated to grade 3 after resuming nivolumab treatment. After cessation of nivolumab, 3.3 mg of intravenous dexamethasone and 40 mg of methylprednisolone were administered for 16 days and subsequently 30-60 mg of oral prednisolone was administered for 50 days, with little improvement in the patient's colitis. A second-line treatment with 5 mg/kg of infliximab was twice attempted, but the patient had persistent diarrhea. Therefore, 50 mg of oral cyclosporine was started as a third-line therapy. Three days after the start of cyclosporine, the number of diarrhea events decreased, with resolution 2 weeks after cyclosporine administration. CONCLUSIONS Oral cyclosporine treatment can be a third-line therapy for enterocolitis associated with immune-related adverse events.

AB - Transition-metal dichalcogenide monolayers have naturally terminated surfaces and can exhibit a near-unity photoluminescence quantum yield in the presence of suitable defect passivation. To date, steady-state monolayer light-emitting devices suffer from Schottky contacts or require complex heterostructures. We demonstrate a transient-mode electroluminescent device based on transition-metal dichalcogenide monolayers (MoS2, WS2, MoSe2, and WSe2) to overcome these problems. Electroluminescence from this dopant-free two-terminal device is obtained by applying an AC voltage between the gate and the semiconductor. Notably, the electroluminescence intensity is weakly dependent on the Schottky barrier height or polarity of the contact. We fabricate a monolayer seven-segment display and achieve the first transparent and bright millimeter-scale light emitting monolayer semiconductor device. PMID- 29581420 TI - Aberrant salience network functional connectivity in auditory verbal hallucinations: a first episode psychosis sample. AB - Auditory verbal hallucinations (AVH) often lead to distress and functional disability, and are frequently associated with psychotic illness. Previously both state and trait magnetic resonance imaging (MRI) studies of AVH have identified activity in brain regions involving auditory processing, language, memory and areas of default mode network (DMN) and salience network (SN). Current evidence is clouded by research mainly in participants on long-term medication, with chronic illness and by choice of seed regions made 'a priori'. Thus, the aim of this study was to elucidate the intrinsic functional connectivity in patients presenting with first episode psychosis (FEP). Resting state functional MRI data were available from 18 FEP patients, 9 of whom also experienced AVH of sufficient duration in the scanner and had symptom capture functional MRI (sc fMRI), together with 18 healthy controls. Symptom capture results were used to accurately identify specific brain regions active during AVH; including the superior temporal cortex, insula, precuneus, posterior cingulate and parahippocampal complex. Using these as seed regions, patients with FEP and AVH showed increased resting sb-FC between parts of the SN and the DMN and between the SN and the cerebellum, but reduced sb-FC between the claustrum and the insula, compared to healthy controls.It is possible that aberrant activity within the DMN and SN complex may be directly linked to impaired salience appraisal of internal activity and AVH generation. Furthermore, decreased intrinsic functional connectivity between the claustrum and the insula may lead to compensatory over activity in parts of the auditory network including areas involved in DMN, auditory processing, language and memory, potentially related to the complex and individual content of AVH when they occur. PMID- 29581421 TI - Lateral habenula perturbation reduces default-mode network connectivity in a rat model of depression. AB - Hyperconnectivity of the default-mode network (DMN) is one of the most widely replicated neuroimaging findings in major depressive disorder (MDD). Further, there is growing evidence for a central role of the lateral habenula (LHb) in the pathophysiology of MDD. There is preliminary neuroimaging evidence linking LHb and the DMN, but no causal relationship has been shown to date. We combined optogenetics and functional magnetic resonance imaging (fMRI), to establish a causal relationship, using an animal model of treatment-resistant depression, namely Negative Cognitive State rats. First, an inhibitory light-sensitive ion channel was introduced into the LHb by viral transduction. Subsequently, laser stimulation was performed during fMRI acquisition on a 9.4 Tesla animal scanner. Neural activity and connectivity were assessed, before, during and after laser stimulation. We observed a connectivity decrease in the DMN following laser induced LHb perturbation. Our data indicate a causal link between LHb downregulation and reduction in DMN connectivity. These findings may advance our mechanistic understanding of LHb inhibition, which had previously been identified as a promising therapeutic principle, especially for treatment-resistant depression. PMID- 29581422 TI - Low-frequency and rare variants may contribute to elucidate the genetics of major depressive disorder. AB - Major depressive disorder (MDD) is a common but serious psychiatric disorder with significant levels of morbidity and mortality. Recent genome-wide association studies (GWAS) on common variants increase our understanding of MDD; however, the underlying genetic basis remains largely unknown. Many studies have been proposed to explore the genetics of complex diseases from a viewpoint of the "missing heritability" by considering low-frequency and rare variants, copy-number variations, and other types of genetic variants. Here we developed a novel computational and statistical strategy to investigate the "missing heritability" of MDD. We applied Hamming distance on common, low-frequency, and rare single nucleotide polymorphism (SNP) sets to measure genetic distance between two individuals, and then built the multi-dimensional scaling (MDS) pictures. Whole exome genotyping data from a Los Angeles Mexican-American cohort (203 MDD and 196 controls) and a European-ancestry cohort (473 MDD and 497 controls) were examined using our proposed methodology. MDS plots showed very significant separations between MDD cases and healthy controls for low-frequency SNP set (P value < 2.2e 16) and rare SNP set (P value = 7.681e-12). Our results suggested that low frequency and rare variants may play more significant roles in the genetics of MDD. PMID- 29581423 TI - Effects on gene expression and behavior of untagged short tandem repeats: the case of arginine vasopressin receptor 1a (AVPR1a) and externalizing behaviors. AB - Genome-wide association studies (GWAS) of complex, heritable, behavioral phenotypes have yielded an incomplete accounting of the genetic influences. The identified loci explain only a portion of the observed heritability, and few of the loci have been shown to be functional. It is clear that current GWAS techniques overlook key components of phenotypically relevant genetic variation, either because of sample size, as is frequently asserted, or because of methodology. Here we use arginine vasopressin receptor 1a (AVPR1a) as an in-depth model of a methodologic limitation of GWAS: the functional genetic variation (in the form of short tandem repeats) of this key gene involved in affiliative behavior cannot be captured by current GWAS methodologies. Importantly, we find evidence of differential allele expression, twofold or more, in at least a third of human brain samples heterozygous for a reporter SNP in the AVPR1a transcript. We also show that this functional effect and a downstream phenotype, externalizing behavior, are predicted by AVPR1a STRs but not SNPs. PMID- 29581424 TI - A comprehensive map coupling histone modifications with gene regulation in adult dopaminergic and serotonergic neurons. AB - The brain is composed of hundreds of different neuronal subtypes, which largely retain their identity throughout the lifespan of the organism. The mechanisms governing this stability are not fully understood, partly due to the diversity and limited size of clinically relevant neuronal populations, which constitute a technical challenge for analysis. Here, using a strategy that allows for ChIP-seq combined with RNA-seq in small neuronal populations in vivo, we present a comparative analysis of permissive and repressive histone modifications in adult midbrain dopaminergic neurons, raphe nuclei serotonergic neurons, and embryonic neural progenitors. Furthermore, we utilize the map generated by our analysis to show that the transcriptional response of midbrain dopaminergic neurons following 6-OHDA or methamphetamine injection is characterized by increased expression of genes with promoters dually marked by H3K4me3/H3K27me3. Our study provides an in vivo genome-wide analysis of permissive/repressive histone modifications coupled to gene expression in these rare neuronal subtypes.

AB - Understanding the unique contributions of frontoparietal networks (FPN) in cognition is challenging because they overlap spatially and are co-activated by diverse tasks. Characterizing these networks therefore involves studying their activation across many different cognitive tasks, which previously was only possible with meta-analyses. Here, we use neuroadaptive Bayesian optimization, an approach combining real-time analysis of functional neuroimaging data with machine-learning, to discover cognitive tasks that segregate ventral and dorsal FPN activity. We identify and subsequently refine two cognitive tasks, Deductive Reasoning and Tower of London, which maximally dissociate the dorsal from ventral FPN. We subsequently investigate these two FPNs in the context of a wider range of FPNs and demonstrate the importance of studying the whole activity profile across tasks to uniquely differentiate any FPN. Our findings deviate from previous meta-analyses and hypothesized functional labels for these FPNs. Taken together the results form the starting point for a neurobiologically-derived cognitive taxonomy. PMID- 29581426 TI - A semi-synthetic regulon enables rapid growth of yeast on xylose. AB - Nutrient assimilation is the first step that allows biological systems to proliferate and produce value-added products. Yet, implementation of heterologous catabolic pathways has so far relied on constitutive gene expression without consideration for global regulatory systems that may enhance nutrient assimilation and cell growth. In contrast, natural systems prefer nutrient responsive gene regulation (called regulons) that control multiple cellular functions necessary for cell survival and growth. Here, in Saccharomyces cerevisiae, by partially- and fully uncoupling galactose (GAL)-responsive regulation and metabolism, we demonstrate the significant growth benefits conferred by the GAL regulon. Next, by adapting the various aspects of the GAL regulon for a non-native nutrient, xylose, we build a semi-synthetic regulon that exhibits higher growth rate, better nutrient consumption, and improved growth fitness compared to the traditional and ubiquitous constitutive expression strategy. This work provides an elegant paradigm to integrate non-native nutrient catabolism with native, global cellular responses to support fast growth. PMID- 29581427 TI - TRIM11 activates the proteasome and promotes overall protein degradation by regulating USP14. AB - The proteasome is a complex protease critical for protein quality control and cell regulation, and its dysfunction is associated with cancer and other diseases. However, the mechanisms that control proteasome activity in normal and malignant cells remain unclear. Here we report that TRIM11 enhances degradation of aberrant and normal regulatory proteins, and augments overall rate of proteolysis. Mechanistically, TRIM11 binds to both the proteasome and USP14, a deubiquitinase that prematurely removes ubiquitins from proteasome-bound substrates and also noncatalytically inhibits the proteasome, and precludes their association, thereby increasing proteasome activity. TRIM11 promotes cell survival and is upregulated upon heat shock. Moreover, TRIM11 is required for tumor growth, and increased expression of TRIM11 correlates with poor clinical survival. These findings identify TRIM11 as an important activator of the proteasome, define a pathway that adjusts proteasome activity, and reveal a mechanism by which tumor cells acquire higher degradative power to support oncogenic growth. PMID- 29581428 TI - Divergent midbrain circuits orchestrate escape and freezing responses to looming stimuli in mice. AB - Animals respond to environmental threats, e.g. looming visual stimuli, with innate defensive behaviors such as escape and freezing. The key neural circuits that participate in the generation of such dimorphic defensive behaviors remain unclear. Here we show that the dimorphic behavioral patterns triggered by looming visual stimuli are mediated by parvalbumin-positive (PV+) projection neurons in mouse superior colliculus (SC). Two distinct groups of SC PV+ neurons form divergent pathways to transmit threat-relevant visual signals to neurons in the parabigeminal nucleus (PBGN) and lateral posterior thalamic nucleus (LPTN). Activations of PV+ SC-PBGN and SC-LPTN pathways mimic the dimorphic defensive behaviors. The PBGN and LPTN neurons are co-activated by looming visual stimuli. Bilateral inactivation of either nucleus results in the defensive behavior dominated by the other nucleus. Together, these data suggest that the SC orchestrates dimorphic defensive behaviors through two separate tectofugal pathways that may have interactions.

AB - Catalytic transformation of CH4 under a mild condition is significant for efficient utilization of shale gas under the circumstance of switching raw materials of chemical industries to shale gas. Here, we report the transformation of CH4 to acetic acid and methanol through coupling of CH4, CO and O2 on single site Rh1O5 anchored in microporous aluminosilicates in solution at <=150 degrees C. The activity of these singly dispersed precious metal sites for production of organic oxygenates can reach about 0.10 acetic acid molecules on a Rh1O5 site per second at 150 degrees C with a selectivity of ~70% for production of acetic acid. It is higher than the activity of free Rh cations by >1000 times. Computational studies suggest that the first C-H bond of CH4 is activated by Rh1O5 anchored on the wall of micropores of ZSM-5; the formed CH3 then couples with CO and OH, to produce acetic acid over a low activation barrier. PMID- 29581430 TI - LFP beta amplitude is linked to mesoscopic spatio-temporal phase patterns. AB - Beta oscillations observed in motor cortical local field potentials (LFPs) recorded on separate electrodes of a multi-electrode array have been shown to exhibit non-zero phase shifts that organize into planar waves. Here, we generalize this concept to additional classes of salient patterns that fully describe the spatial organization of beta oscillations. During a delayed reach-to grasp task we distinguish planar, synchronized, random, circular, and radial phase patterns in monkey primary motor and dorsal premotor cortices. We observe that patterns correlate with the beta amplitude (envelope): Coherent planar/radial wave propagation accelerates with growing amplitude, and synchronized patterns are observed at largest amplitudes. In contrast, incoherent random or circular patterns are observed almost exclusively when beta is strongly attenuated. The occurrence probability of a particular pattern modulates with behavioral epochs in the same way as beta amplitude: Coherent patterns are more present during movement preparation where amplitudes are large, while incoherent phase patterns are dominant during movement execution where amplitudes are small. Thus, we uncover a trigonal link between the spatial arrangement of beta phases, beta amplitude, and behavior. Together with previous findings, we discuss predictions on the spatio-temporal organization of precisely coordinated spiking on the mesoscopic scale as a function of beta power. PMID- 29581431 TI - Urban and nomadic isotopic niches reveal dietary connectivities along Central Asia's Silk Roads. AB - The ancient 'Silk Roads' formed a vast network of trade and exchange that facilitated the movement of commodities and agricultural products across medieval Central Asia via settled urban communities and mobile pastoralists. Considering food consumption patterns as an expression of socio-economic interaction, we analyse human remains for carbon and nitrogen isotopes in order to establish dietary intake, then model isotopic niches to characterize dietary diversity and infer connectivity among communities of urbanites and nomadic pastoralists. The combination of low isotopic variation visible within urban groups with isotopic distinction between urban communities irrespective of local environmental conditions strongly suggests localized food production systems provided primary subsistence rather than agricultural goods exchanged along trade routes. Nomadic communities, in contrast, experienced higher dietary diversity reflecting engagements with a wide assortment of foodstuffs typical for mobile communities. These data indicate tightly bound social connectivity in urban centres pointedly funnelled local food products and homogenized dietary intake within settled communities, whereas open and opportunistic systems of food production and circulation were possible through more mobile lifeways. PMID- 29581432 TI - Maternal deprivation induces alterations in cognitive and cortical function in adulthood. AB - Early life trauma is a risk factor for a number of neuropsychiatric disorders, including schizophrenia (SZ). The current study assessed how an early life traumatic event, maternal deprivation (MD), alters cognition and brain function in rodents. Rats were maternally deprived in the early postnatal period and then recognition memory (RM) was tested in adulthood using the novel object recognition task. The expression of catechol-o-methyl transferase (COMT) and glutamic acid decarboxylase (GAD67) were quantified in the medial prefrontal cortex (mPFC), ventral striatum, and temporal cortex (TC). In addition, depth EEG recordings were obtained from the mPFC, vertex, and TC during a paired-click paradigm to assess the effects of MD on sensory gating. MD animals exhibited impaired RM, lower expression of COMT in the mPFC and TC, and lower expression of GAD67 in the TC. Increased bioelectric noise was observed at each recording site of MD animals. MD animals also exhibited altered information theoretic measures of stimulus encoding. These data indicate that a neurodevelopmental perturbation yields persistent alterations in cognition and brain function, and are consistent with human studies that identified relationships between allelic differences in COMT and GAD67 and bioelectric noise. These changes evoked by MD also lead to alterations in shared information between cognitive and primary sensory processing areas, which provides insight into how early life trauma confers a risk for neurodevelopmental disorders, such as SZ, later in life. PMID- 29581433 TI - Silicon and glass very large scale microfluidic droplet integration for terascale generation of polymer microparticles. AB - Microfluidic chips can generate emulsions, which can be used to synthesize polymer microparticles that have superior pharmacological performance compared to particles prepared by conventional techniques. However, low production rates of microfluidics remains a challenge to successfully translate laboratory discoveries to commercial manufacturing. We present a silicon and glass device that incorporates an array of 10,260 (285 * 36) microfluidic droplet generators that uses only a single set of inlets and outlets, increasing throughput by >10,000* compared to microfluidics with a single generator. Our design breaks the tradeoff between the number of generators and the maximum throughput of individual generators by incorporating high aspect ratio flow resistors. We test these design strategies by generating hexadecane microdroplets at >1 trillion droplets per h with a coefficient of variation CV <3%. To demonstrate the synthesis of biocompatible microparticles, we generated 8-16 um polycaprolactone particles with a CV <5% at a rate of 277 g h-1. PMID- 29581434 TI - Organic osmolytes preserve the function of the developing tight junction in ultraviolet B-irradiated rat epidermal keratinocytes. AB - Epidermal barrier function is provided by the highly keratinised stratum corneum and also by tight junctions (TJs) in the granular layer of skin. The development of the TJ barrier significantly deteriorates in response to ultraviolet B radiation (UVB). Following exposure to UVB, keratinocytes accumulate organic osmolytes, which are known to preserve cell volume during water stress. Since TJs are intimately associated with control of water homeostasis in skin, we hypothesised that there may be a direct influence of osmolytes on TJ development. Exposure of rat epidermal keratinocytes (REKs) to a single dose of UVB reduced the function of developing TJs. This was concomitant with dislocalisation of claudin-1 and claudin-4 from the keratinocyte plasma membrane, phosphorylation of occludin and elevation of reactive oxygen species (ROS). In the presence of organic osmolytes, these effects were negated but were independent of the effects of these molecules on cell volume, elevation of ROS or the gene expression of TJ proteins. These data suggest that organic osmolytes affect TJs via post translational mechanism(s) possibly involving protection of the native conformation of TJ proteins. PMID- 29581435 TI - Correlation of Xpert MTB/RIF with measures to assess Mycobacterium tuberculosis bacillary burden in high HIV burden areas of Southern Africa. AB - Traditionally, smear microscopy has been used as a point-of-care measure of bacillary burden in tuberculosis patients to inform infection control and contact tracing. Xpert MTB/RIF has the potential to replace smear. However, data to support the use of its quantitative output [cycle threshold (CT)] as an alternate point-of-care measure of bacillary burden are limited. This study assessed the correlation (Spearman's) between CT, smear, culture time-to-positivity (TTP), and clinical factors in patients with Xpert-positive sputum from Mozambique (n = 238) and South Africa (n = 462). Mean CT and smear grade correlated well (rho0.72); compared to TTP and smear (rho0.61); and mean CT and TTP (rho0.50). In multivariate analyses, lower CT (higher bacillary load) was associated with negative HIV serostatus and low BMI. A smear positivity rule-out (95% sensitivity) CT cut-off of 28.0 was identified, with 54.1% specificity, 2.07 positive likelihood ratio, 0.09 negative likelihood ratio and 79.0% correctly classified. Cut-offs were higher for HIV positive compared to HIV negative individuals for any set sensitivity level. This study suggests Xpert CT values correlate well with smear, both in HIV positive and negative individuals, and that CT cut-offs might be broadly applicable to multiple settings. Studies to directly assess the association of CT with infectiousness are needed. PMID- 29581436 TI - A highly efficient Cu(In,Ga)(S,Se)2 photocathode without a hetero-materials overlayer for solar-hydrogen production. AB - Surface modification of a Cu(In,Ga)(S,Se)2 (CIGSSe) absorber layer is commonly required to obtain high performance CIGSSe photocathodes. However, surface modifications can cause disadvantages such as optical loss, low stability, the use of toxic substances and an increase in complexity. In this work, we demonstrate that a double-graded bandgap structure (top-high, middle-low and bottom-high bandgaps) can achieve high performance in bare CIGSSe photocathodes without any surface modifications via a hetero-materials overlayer that have been fabricated in a cost-effective solution process. We used two kinds of CIGSSe film produced by different precursor solutions consisting of different solvents and binder materials, and both revealed a double-graded bandgap structure composed of an S-rich top layer, Ga- and S-poor middle layer and S- and Ga-rich bottom layer. The bare CIGSSe photocathode without surface modification exhibited a high photoelectrochemical activity of ~6 mA.cm-2 at 0 V vs. RHE and ~22 mA.cm-2 at 0.27 V vs. RHE, depending on the solution properties used in the CIGSSe film preparation. The incorporation of a Pt catalyst was found to further increase their PEC activity to ~26 mA.cm-2 at -0.16 V vs. RHE. PMID- 29581437 TI - Orthogonality of Pyrrolysine tRNA in the Xenopus oocyte. AB - Chemical aminoacylation of orthogonal tRNA allows for the genetic encoding of a wide range of synthetic amino acids without the need to evolve specific aminoacyl tRNA synthetases. This method, when paired with protein expression in the Xenopus laevis oocyte expression system, can extract atomic scale functional data from a protein structure to advance the study of membrane proteins. The utility of the method depends on the orthogonality of the tRNA species used to deliver the amino acid. Here, we report that the pyrrolysyl tRNA (pylT) from Methanosarcina barkeri fusaro is orthogonal and highly competent for genetic code expansion experiments in the Xenopus oocyte. The data show that pylT is amendable to chemical acylation in vitro; it is then used to rescue a cytoplasmic site within a voltage-gated sodium channel. Further, the high fidelity of the pylT is demonstrated via encoding of lysine within the selectivity filter of the sodium channel, where sodium ion recognition by the distal amine of this side-chain is essential. Thus, pylT is an appropriate tRNA species for delivery of amino acids via nonsense suppression in the Xenopus oocyte. It may prove useful in experimental contexts wherein reacylation of suppressor tRNAs have been observed. PMID- 29581438 TI - Structural modelling of the DNAJB6 oligomeric chaperone shows a peptide-binding cleft lined with conserved S/T-residues at the dimer interface. AB - The remarkably efficient suppression of amyloid fibril formation by the DNAJB6 chaperone is dependent on a set of conserved S/T-residues and an oligomeric structure, features unusual among DNAJ chaperones. We explored the structure of DNAJB6 using a combination of structural methods. Lysine-specific crosslinking mass spectrometry provided distance constraints to select a homology model of the DNAJB6 monomer, which was subsequently used in crosslink-assisted docking to generate a dimer model. A peptide-binding cleft lined with S/T-residues is formed at the monomer-monomer interface. Mixed isotope crosslinking showed that the oligomers are dynamic entities that exchange subunits. The purified protein is well folded, soluble and composed of oligomers with a varying number of subunits according to small-angle X-ray scattering (SAXS). Elongated particles (160 * 120 A) were detected by electron microscopy and single particle reconstruction resulted in a density map of 20 A resolution into which the DNAJB6 dimers fit. The structure of the oligomer and the S/T-rich region is of great importance for the understanding of the function of DNAJB6 and how it can bind aggregation-prone peptides and prevent amyloid diseases. PMID- 29581439 TI - A micro-CT-based method for quantitative brain lesion characterization and electrode localization. AB - Lesion verification and quantification is traditionally done via histological examination of sectioned brains, a time-consuming process that relies heavily on manual estimation. Such methods are particularly problematic in posterior cortical regions (e.g. visual cortex), where sectioning leads to significant damage and distortion of tissue. Even more challenging is the post hoc localization of micro-electrodes, which relies on the same techniques, suffers from similar drawbacks and requires even higher precision. Here, we propose a new, simple method for quantitative lesion characterization and electrode localization that is less labor-intensive and yields more detailed results than conventional methods. We leverage staining techniques standard in electron microscopy with the use of commodity micro-CT imaging. We stain whole rat and zebra finch brains in osmium tetroxide, embed these in resin and scan entire brains in a micro-CT machine. The scans result in 3D reconstructions of the brains with section thickness dependent on sample size (12-15 and 5-6 microns for rat and zebra finch respectively) that can be segmented manually or automatically. Because the method captures the entire intact brain volume, comparisons within and across studies are more tractable, and the extent of lesions and electrodes may be studied with higher accuracy than with current methods. PMID- 29581440 TI - Three-dimensional Epigenome Statistical Model: Genome-wide Chromatin Looping Prediction. AB - This study aims to understand through statistical learning the basic biophysical mechanisms behind three-dimensional folding of epigenomes. The 3DEpiLoop algorithm predicts three-dimensional chromatin looping interactions within topologically associating domains (TADs) from one-dimensional epigenomics and transcription factor profiles using the statistical learning. The predictions obtained by 3DEpiLoop are highly consistent with the reported experimental interactions. The complex signatures of epigenomic and transcription factors within the physically interacting chromatin regions (anchors) are similar across all genomic scales: genomic domains, chromosomal territories, cell types, and different individuals. We report the most important epigenetic and transcription factor features used for interaction identification either shared, or unique for each of sixteen (16) cell lines. The analysis shows that CTCF interaction anchors are enriched by transcription factors yet deficient in histone modifications, while the opposite is true in the case of RNAP II mediated interactions. The code is available at the repository https://bitbucket.org/4dnucleome/3depiloop . PMID- 29581441 TI - Metabolomic Prediction of Human Prostate Cancer Aggressiveness: Magnetic Resonance Spectroscopy of Histologically Benign Tissue. AB - Prostate cancer alters cellular metabolism through events potentially preceding cancer morphological formation. Magnetic resonance spectroscopy (MRS)-based metabolomics of histologically-benign tissues from cancerous prostates can predict disease aggressiveness, offering clinically-translatable prognostic information. This retrospective study of 185 patients (2002-2009) included prostate tissues from prostatectomies (n = 365), benign prostatic hyperplasia (BPH) (n = 15), and biopsy cores from cancer-negative patients (n = 14). Tissues were measured with high resolution magic angle spinning (HRMAS) MRS, followed by quantitative histology using the Prognostic Grade Group (PGG) system. Metabolic profiles, measured solely from 338 of 365 histologically-benign tissues from cancerous prostates and divided into training-testing cohorts, could identify tumor grade and stage, and predict recurrence. Specifically, metabolic profiles: (1) show elevated myo-inositol, an endogenous tumor suppressor and potential mechanistic therapy target, in patients with highly-aggressive cancer, (2) identify a patient sub-group with less aggressive prostate cancer to avoid overtreatment if analysed at biopsy; and (3) subdivide the clinicopathologically indivisible PGG2 group into two distinct Kaplan-Meier recurrence groups, thereby identifying patients more at-risk for recurrence. Such findings, achievable by biopsy or prostatectomy tissue measurement, could inform treatment strategies. Metabolomics information can help transform a morphology-based diagnostic system by invoking cancer biology to improve evaluation of histologically-benign tissues in cancer environments. PMID- 29581443 TI - The electromagnetic wave energy effect(s) in microwave-assisted organic syntheses (MAOS). AB - Organic reactions driven by microwaves have been subjected for several years to some enigmatic phenomenon referred to as the microwave effect, an effect often mentioned in microwave chemistry but seldom understood. We identify this microwave effect as an electromagnetic wave effect that influences many chemical reactions. In this article, we demonstrate its existence using three different types of microwave generators with dissimilar oscillation characteristics. We show that this effect is operative in photocatalyzed TiO2 reactions; it negatively influences electro-conductive catalyzed reactions, and yet has but a negligible effect on organic syntheses. The relationship between this electromagnetic wave effect and chemical reactions is elucidated from such energetic considerations as the photon energy and the reactions' activation energies. PMID- 29581442 TI - A vaccinia-based single vector construct multi-pathogen vaccine protects against both Zika and chikungunya viruses. AB - Zika and chikungunya viruses have caused major epidemics and are transmitted by Aedes aegypti and/or Aedes albopictus mosquitoes. The "Sementis Copenhagen Vector" (SCV) system is a recently developed vaccinia-based, multiplication defective, vaccine vector technology that allows manufacture in modified CHO cells. Herein we describe a single-vector construct SCV vaccine that encodes the structural polyprotein cassettes of both Zika and chikungunya viruses from different loci. A single vaccination of mice induces neutralizing antibodies to both viruses in wild-type and IFNAR-/- mice and protects against (i) chikungunya virus viremia and arthritis in wild-type mice, (ii) Zika virus viremia and fetal/placental infection in female IFNAR-/- mice, and (iii) Zika virus viremia and testes infection and pathology in male IFNAR-/- mice. To our knowledge this represents the first single-vector construct, multi-pathogen vaccine encoding large polyproteins, and offers both simplified manufacturing and formulation, and reduced "shot burden" for these often co-circulating arboviruses. PMID- 29581444 TI - Whole Genome Resequencing of Capsicum baccatum and Capsicum annuum to Discover Single Nucleotide Polymorphism Related to Powdery Mildew Resistance. AB - The present study deals with genome wide identification of single-nucleotide polymorphism (SNP) markers related to powdery mildew (PM) resistance in two pepper varieties. Capsicum baccatum (PRH1- a PM resistant line) and Capsicum annuum (Saengryeg- a PM susceptible line), were resequenced to develop SNP markers. A total of 6,213,009 and 6,840,889 SNPs for PRH1 and Saengryeg respectively have been discovered. Among the SNPs, majority were classified as homozygous type SNPs, particularly in the resistant line. Moreover, the SNPs were differentially distributed among the chromosomes in both the resistant and susceptible lines. In total, 4,887,031 polymorphic SNP loci were identified between the two lines and 306,871 high-resolution melting (HRM) marker primer sets were designed. In order to understand the SNPs associated with the vital genes involved in diseases resistance and stress associated processes, chromosome wise gene ontology analysis was performed. The results revealed the occurrence that SNPs related to diseases resistance genes were predominantly distributed in chromosome 4. In addition, 6281 SNPs associated with 46 resistance genes were identified. Among the lines, PRH1 consisted of maximum number of polymorphic SNPs related to NBS-LRR genes. The SNP markers were validated using HRM assay in 45 F4 populations and correlated with the phenotypic disease index. PMID- 29581445 TI - Incongruent pitch cues are associated with increased activation and functional connectivity in the frontal areas. AB - Pitch plays a crucial role in music and speech perception. Pitch perception is characterized by multiple perceptual dimensions, such as pitch height and chroma. Information provided by auditory signals that are related to these perceptual dimensions can be either congruent or incongruent. To create conflicting cues for pitch perception, we modified Shepard tones by varying the pitch height and pitch chroma dimensions in either the same or opposite directions. Our behavioral data showed that most listeners judged pitch changes based on pitch chroma, instead of pitch height, when incongruent information was provided. The reliance on pitch chroma resulted in a stable percept of upward or downward pitch shift, rather than alternating between two different percepts. Across the incongruent and congruent conditions, consistent activation was found in the bilateral superior temporal and inferior frontal areas. In addition, significantly stronger activation was observed in the inferior frontal areas during the incongruent compared to congruent conditions. Enhanced functional connectivity was found between the left temporal and bilateral frontal areas in the incongruent than congruent conditions. Increased intra-hemispheric and inter-hemispheric connectivity was also observed in the frontal areas. Our results suggest the involvement of the frontal lobe in top-down and bottom-up processes to generate a stable percept of pitch change with conflicting perceptual cues. PMID- 29581446 TI - Propensity Score-Matched Analysis on the Association Between Pregnancy Infections and Adverse Birth Outcomes in Rural Northwestern China. AB - The purpose of this study is to examine the relationship between infections and birth outcomes in pregnant Chinese women by using propensity score (PS) matching. The data used here was from a large population-based cross-sectional epidemiological survey on birth defects in Shaanxi province, Northwest China. The babies born during 2010-2013 and their mothers were selected with a stratified multistage sampling method. We used PS-matched (1:1) analysis to match participants with infections to participants without infections. Of 22916 rural participants, the overall prevalence of infection was about 39.96%. 5381 pairs were matched. We observed increased risks of birth defects with infections, respiratory infections and genitourinary infections during the pregnancy (OR, 1.59; 95% CI: 1.21-2.08; OR, 1.44; 95% CI: 1.10-1.87; OR, 3.11; 95% CI: 1.75 5.54). There was also a significant increase of low birth weight associated with respiratory infections (1.13(1.01-1.27)). The association of birth defect with the infection could be relatively stable but the effect could be mediated by some important factors such as mother's age, education level and economic level. The infection during pregnancy is common in Chinese women and might increase the risk of offspring birth defects and low birth weight, especially in younger, lower education, poor pregnant women. PMID- 29581447 TI - Asymmetries in Distractibility: Left Distractors Improve Reaction Time Performance. AB - Research using the irrelevant-distractor paradigm shows perceptual load influences distractibility, such that distractors are more likely to be processed and decrease reaction times during low perceptual load. In contrast, under high load, attentional resources are limited, and the likelihood of distractibility is decreased. We manipulated distractor placement to determine whether location differentially influenced distractibility. During low load, reaction times were increased equally for all distractor locations. Under high load, left distractors speeded reaction times significantly more than right distractors. We suggest two potential explanations: (1) the central focus of attention was sufficiently large to encapsulate both the distractor and the visual array during low perceptual load, leading to increased distraction-during high load, attention was split across the two visual stimuli, allowing the distractors and array to be processed independently; (2) superior executive control for stimuli in the left visual field allowed participants to 'catch and release' left distractors more efficiently, ultimately decreasing distraction and providing a performance benefit. Our findings represent an intriguing development in relation to visual asymmetries in distractibility. PMID- 29581448 TI - Sulfate alters aerosol absorption properties in East Asian outflow. AB - Black carbon (BC) and brown carbon (BrC) aerosols that are released from the combustion of fossil fuels and biomass are of great concern because of their light-absorbing ability and great abundance associated with various anthropogenic sources, particularly in East Asia. However, the optical properties of ambient aerosols are dependent on the mixing state and the chemical composition of absorbing and non-absorbing aerosols. Here we examined how, in East Asian outflows, the parameters of the aerosol optical properties can be altered seasonally in conjunction with the mixing state and the chemical composition of aerosols, using 3-year aerosol measurements. Our findings highlight the important role played by sulfate in East Asia during the warm season in both enhancing single scattering albedo (SSA) and altering the absorption properties of aerosols enhancing mass absorption cross section of BC (MACBC) and reducing MAC of BrC (MACBrC,370). Therefore we suggest that in global radiative forcing models, particular attention should be paid to the consideration of the accurate treatment of the SO2 emission changes in the coming years in this region that will result from China's air quality policy. PMID- 29581449 TI - Adipose mesenchymal stem cells from osteoporotic donors preserve functionality and modulate systemic inflammatory microenvironment in osteoporotic cytotherapy. AB - Maintenance of bone homeostasis against diseased microenvironments remains as a major challenge. Recently, mesenchymal stem cells (MSCs) have been unravelled as potent microenvironmental modulators, the systemic infusion of which in cytotherapy can prevent or rescue extensive bone loss via anti-inflammation. However, MSCs also accept microenvironmental regulations; particularly, MSCs from bone marrow (BMMSCs) are prone to pathological microenvironmental factors of bone. In this study, we discovered that BMMSCs from osteoporotic donors of ovariectomized (OVX) mice lost their anti-inflammatory capability and failed to prevent bone loss when infused back into OVX recipients. Nevertheless, MSCs from adipose tissues (ADMSCs) preserved their anti-inflammatory capacity, despite diseased microenvironments of OVX donors, and continued to show protective effects on bone in OVX recipients. In the cellular level, the anti-inflammatory superiority of osteoporotic donor-derived ADMSCs over BMMSCs existed in their distinctive capability to induce T-cell apoptosis, which was molecularly attributed to retained expression levels of critical immunomodulatory genes. Furthermore, these functional discrepancies of BMMSCs and ADMSCs were due to differential stemness, energy metabolism and anti-oxidative defence system, underlying general disparity in their cellular states. Collectively, our findings optimize osteoporotic cytotherapy by using ADMSCs in resistance to and in modulation of diseased microenvironments. PMID- 29581450 TI - Methylation-to-Expression Feature Models of Breast Cancer Accurately Predict Overall Survival, Distant-Recurrence Free Survival, and Pathologic Complete Response in Multiple Cohorts. AB - Prognostic biomarkers serve a variety of purposes in cancer treatment and research, such as prediction of cancer progression, and treatment eligibility. Despite growing interest in multi-omic data integration for defining prognostic biomarkers, validated methods have been slow to emerge. Given that breast cancer has been the focus of intense research, it is amenable to studying the benefits of multi-omic prognostic models due to the availability of datasets. Thus, we examined the efficacy of our methylation-to-expression feature model (M2EFM) approach to combining molecular and clinical predictors to create risk scores for overall survival, distant metastasis, and chemosensitivity in breast cancer. Gene expression, DNA methylation, and clinical variables were integrated via M2EFM to build models of overall survival using 1028 breast tumor samples and applied to validation cohorts of 61 and 327 samples. Models of distant recurrence-free survival and pathologic complete response were built using 306 samples and validated on 182 samples. Despite different populations and assays, M2EFM models validated with good accuracy (C-index or AUC >= 0.7) for all outcomes and had the most consistent performance compared to other methods. Finally, we demonstrated that M2EFM identifies functionally relevant genes, which could be useful in translating an M2EFM biomarker to the clinic. PMID- 29581451 TI - Modeling the effects of lipid peroxidation during ferroptosis on membrane properties. AB - Ferroptosis is a form of regulated cell death characterized by the accumulation of lipid hydroperoxides. There has been significant research on the pathways leading to the accumulation of oxidized lipids, but the downstream effects and how lipid peroxides cause cell death during ferroptosis remain a major puzzle. We evaluated key features of ferroptosis in newly developed molecular dynamics models of lipid membranes to investigate the biophysical consequences of lipid peroxidation, and generated hypotheses about how lipid peroxides contribute to cell death during ferroptosis. PMID- 29581453 TI - Extracting quasi-steady Lagrangian transport patterns from the ocean circulation: An application to the Gulf of Mexico. AB - We construct a climatology of Lagrangian coherent structures (LCSs)-the concealed skeleton that shapes transport-with a twelve-year-long data-assimilative simulation of the sea-surface circulation in the Gulf of Mexico (GoM). Computed as time-mean Cauchy-Green strain tensorlines of the climatological velocity, the climatological LCSs (cLCSs) unveil recurrent Lagrangian circulation patterns. The cLCSs strongly constrain the ensemble-mean Lagrangian circulation of the instantaneous model velocity, showing that a climatological velocity can preserve meaningful transport information. The quasi-steady transport patterns revealed by the cLCSs agree well with aspects of the GoM circulation described in several previous observational and numerical studies. For example, the cLCSs identify regions of persistent isolation, and suggest that coastal regions previously identified as high-risk for pollution impact are regions of maximal attraction. We also show that cLCSs are remarkably accurate at identifying transport patterns observed during the Deepwater Horizon and Ixtoc oil spills, and during the Grand LAgrangian Deployment (GLAD) experiment. Thus it is shown that computing cLCSs is an efficient and meaningful way of synthesizing vast amounts of Lagrangian information. The cLCS method confirms previous GoM studies, and contributes to our understanding by revealing the persistent nature of the dynamics and kinematics treated therein.

AB - We propose a novel semi-automatic approach to design biomarkers for capturing pharmacodynamic effects induced by pharmacological agents on the spectral power of electroencephalography (EEG) recordings. We apply this methodology to investigate the pharmacodynamic effects of methylphenidate (MPH) and atomoxetine (ATX) on attention deficit/hyperactivity disorder (ADHD), using rodent models. We inject the two agents into the spontaneously hypertensive rat (SHR) model of ADHD, the Wistar-Kyoto rat (WKY), and the Wistar rat (WIS), and record their EEG patterns. To assess individual EEG patterns quantitatively, we use an integrated methodological approach, which consists of calculating the mean, slope and intercept parameters of temporal records of EEG spectral power using a smoothing filter, outlier truncation, and linear regression. We apply Fisher discriminant analysis (FDA) to identify dominant discriminants to be heuristically consolidated into several new composite biomarkers. Results of the analysis of variance (ANOVA) and t-test show benefits in pharmacodynamic parameters, especially the slope parameter. Composite biomarker evaluation confirms their validity for genetic model stratification and the effects of the pharmacological agents used. The methodology proposed is of generic use as an approach to investigating thoroughly the dynamics of the EEG spectral power. PMID- 29581454 TI - Resonance interaction energy between two entangled atoms in a photonic bandgap environment. AB - We consider the resonance interaction energy between two identical entangled atoms, where one is in the excited state and the other in the ground state. They interact with the quantum electromagnetic field in the vacuum state and are placed in a photonic-bandgap environment with a dispersion relation quadratic near the gap edge and linear for low frequencies, while the atomic transition frequency is assumed to be inside the photonic gap and near its lower edge. This problem is strictly related to the coherent resonant energy transfer between atoms in external environments. The analysis involves both an isotropic three dimensional model and the one-dimensional case. The resonance interaction asymptotically decays faster with distance compared to the free-space case, specifically as 1/r2 compared to the 1/r free-space dependence in the three dimensional case, and as 1/r compared to the oscillatory dependence in free space for the one-dimensional case. Nonetheless, the interaction energy remains significant and much stronger than dispersion interactions between atoms. On the other hand, spontaneous emission is strongly suppressed by the environment and the correlated state is thus preserved by the spontaneous-decay decoherence effects. We conclude that our configuration is suitable for observing the elusive quantum resonance interaction between entangled atoms.

AB - The neural mechanisms of visual perceptual learning (VPL) remain unclear. Previously we found that activation in the primary visual cortex (V1) increased in the early encoding phase of training, but returned to baseline levels in the later retention phase. To examine neural changes during the retention phase, we measured structural and functional connectivity changes using MRI. After weeks of training on a texture discrimination task, the fractional anisotropy of the inferior longitudinal fasciculus, a major tract connecting visual and anterior areas, was increased, as well as the functional connectivity between V1 and anterior regions mediated by the ILF. These changes were strongly correlated with behavioral performance improvements. These results suggest a two-phase model of VPL in which localized functional changes in V1 in the encoding phase of training are followed by changes in both structural and functional connectivity in ventral visual processing, perhaps leading to the long-term stabilization of VPL. PMID- 29581456 TI - Sex Genotyping of Archival Fixed and Immunolabeled Guinea Pig Cochleas. AB - For decades, outbred guinea pigs (GP) have been used as research models. Various past research studies using guinea pigs used measures that, unknown at the time, may be sex-dependent, but from which today, archival tissues may be all that remain. We aimed to provide a protocol for sex-typing archival guinea pig tissue, whereby past experiments could be re-evaluated for sex effects. No PCR sex genotyping protocols existed for GP. We found that published sequence of the GP Sry gene differed from that in two separate GP stocks. We used sequences from other species to deduce PCR primers for Sry. After developing a genomic DNA extraction for archival, fixed, decalcified, immunolabeled, guinea pig cochlear half-turns, we used a multiplex assay (Y-specific Sry; X-specific Dystrophin) to assign sex to tissue as old as 3 years. This procedure should allow reevaluation of prior guinea pig studies in various research areas for the effects of sex on experimental outcomes. PMID- 29581457 TI - Counterregulation of cAMP-directed kinase activities controls ciliogenesis. AB - The primary cilium emanates from the cell surface of growth-arrested cells and plays a central role in vertebrate development and tissue homeostasis. The mechanisms that control ciliogenesis have been extensively explored. However, the intersection between GPCR signaling and the ubiquitin pathway in the control of cilium stability are unknown. Here we observe that cAMP elevation promotes cilia resorption. At centriolar satellites, we identify a multimeric complex nucleated by PCM1 that includes two kinases, NEK10 and PKA, and the E3 ubiquitin ligase CHIP. We show that NEK10 is essential for ciliogenesis in mammals and for the development of medaka fish. PKA phosphorylation primes NEK10 for CHIP-mediated ubiquitination and proteolysis resulting in cilia resorption. Disarrangement of this control mechanism occurs in proliferative and genetic disorders. These findings unveil a pericentriolar kinase signalosome that efficiently links the cAMP cascade with the ubiquitin-proteasome system, thereby controlling essential aspects of ciliogenesis.

AB - Mapping of MR fiber g-ratio, which is the ratio of the diameter of the axon to the diameter of the neuronal fiber, is introduced in this article. We investigated the MR fiber g-ratio, the axon volume fraction (AVF) and the myelin volume fraction (MVF) to evaluate microstructural changes in the spinal cord in patients with cervical spondylotic myelopathy (CSM) in vivo, using atlas-based analysis. We used diffusion MRI data acquired with a new simultaneous multi-slice accelerated readout-segmented echo planar imaging sequence for diffusion analysis for AVF calculation and magnetization transfer saturation imaging for MVF calculation. The AVFs of fasciculus gracilis in the affected side spinal cord, fasciculus cuneatus and lateral corticospinal tracts (LSCT) in the affected and unaffected side spinal cord were significantly lower (P = 0.019, 0.001, 0019, 0.000, and 0.002, respectively) than those of normal controls. No difference was found in the MVFs. The fiber g-ratio of LSCT was significantly lower (P = 0.040) in the affected side spinal cords than in the normal controls. The pathological microstructural changes in the spinal cord in patients with CSM, presumably partial axonal degenerations with preserved myelin. This technique has the potential to be a clinical biomarker in patients with CSM in vivo. PMID- 29581459 TI - Predictors and estimation of risk for early exit from working life by poor health among middle and older aged workers in Korea. AB - The aims of this study were to investigate the predictors and estimate the risk for early exit from work owing to poor personal health status of the retirees. This study analysed the longitudinal data of 2,708 workers aged more than 45 years old from the Korean Longitudinal Study of Ageing. Multivariate Cox regression analyses were conducted to identify the predictors and to build a prediction model for early exit from work due to poor health. Internal validation was performed using random split, and external validation using the English Longitudinal Study of Ageing. Over the 8-year follow-up, 124 workers exited work early because of poor health. Significant predictors for early exit from work due to poor health included hypertension (hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.01-2.28), abnormal body mass index (HR, 1.60; 95% CI, 1.10 2.35), decreased grasping power index, and perceived health status. The prediction model designed to estimate the risk of unwanted early exit from work because of poor health status showed fair performance in both the internal and external validations. The current study revealed the specific determinants and the possibility of prediction of shortened working life due to poor health status. PMID- 29581460 TI - Loss of Stemness, EMT, and Supernumerary Tooth Formation in Cebpb-/-Runx2+/- Murine Incisors. AB - Adult Cebpb KO mice incisors present amelogenin-positive epithelium pearls, enamel and dentin allopathic hyperplasia, fewer Sox2-positive cells in labial cervical loop epitheliums, and reduced Sox2 expression in enamel epithelial stem cells. Thus, Cebpb acts upstream of Sox2 to regulate stemness. In this study, Cebpb KO mice demonstrated cementum-like hard tissue in dental pulp, loss of polarity by ameloblasts, enamel matrix in ameloblastic layer, and increased expression of epithelial-mesenchymal transition (EMT) markers in a Cebpb knockdown mouse enamel epithelial stem cell line. Runx2 knockdown in the cell line presented a similar expression pattern. Therefore, the EMT enabled disengaged odontogenic epithelial stem cells to develop supernumerary teeth. Cebpb and Runx2 knockdown in the cell line revealed higher Biglycan and Decorin expression, and Decorin-positive staining in the periapical region, indicating their involvement in supernumerary tooth formation. Cebpb and Runx2 acted synergistically and played an important role in the formation of supernumerary teeth in adult incisors. PMID- 29581461 TI - Transcriptome-wide identification and screening of WRKY factors involved in the regulation of taxol biosynthesis in Taxus chinensis. AB - WRKY, a plant-specific transcription factor family, plays important roles in pathogen defense, abiotic cues, phytohormone signaling, and regulation of plant secondary metabolism. However, little is known about the roles, functions, and mechanisms of WRKY in taxane biosynthesis in Taxus spp. In this study, 61 transcripts were identified from Taxus chinensis transcriptome datasets by using hidden Markov model search. All of these transcripts encoded proteins containing WRKY domains, which were designated as TcWRKY1-61. After phylogenetic analysis of the WRKY domains of TcWRKYs and AtWRKYs, 16, 8, 10, 14, 5, 7, and 1 TcWRKYs were cladded into Group I, IIa-IIe, and III, respectively. Then, six representative TcWRKYs were selected to classify their effects on taxol biosynthesis. After MeJA (methyl jasmonate acid) and SA (salicylic acid) treatments, all of the six TcWRKYs were upregulated by MeJA treatment. TcWRKY44 (IId) and TcWRKY47 (IIa) were upregulated, whereas TcWRKY8 (IIc), TcWRKY20 (III), TcWRKY26 (I), TcWRKY41 (IIe), and TcWRKY52 (IIb) were downregulated by SA treatment. Overexpression experiments showed that the six selected TcWRKYs exerted different effects on taxol biosynthesis. In specific, TcWRKY8 and TcWRKY47 significantly improved the expression levels of taxol-biosynthesis-related genes. Transcriptome-wide identification of WRKY factors in Taxus not only enhances our understanding of plant WRKY factors but also identifies candidate regulators of taxol biosynthesis. PMID- 29581462 TI - Persistent random deformation model of cells crawling on a gel surface. AB - In general, cells move on a substrate through extension and contraction of the cell body. Though cell movement should be explained by taking into account the effect of such shape fluctuations, past approaches to formulate cell-crawling have not sufficiently quantified the relationship between cell movement (velocity and trajectory) and shape fluctuations based on experimental data regarding actual shaping dynamics. To clarify this relationship, we experimentally characterized cell-crawling in terms of shape fluctuations, especially extension and contraction, by using an elasticity-tunable gel substrate to modulate cell shape. As a result, an amoeboid swimmer-like relation was found to arise between the cell velocity and cell-shape dynamics. To formulate this experimentally obtained relationship between cell movement and shaping dynamics, we established a persistent random deformation (PRD) model based on equations of a deformable self-propelled particle adopting an amoeboid swimmer-like velocity-shape relationship. The PRD model successfully explains the statistical properties of velocity, trajectory and shaping dynamics of the cells including back-and-forth motion, because the velocity equation exhibits time-reverse symmetry, which is essentially different from previous models. We discuss the possible application of this model to classify the phenotype of cell migration based on the characteristic relation between movement and shaping dynamics. PMID- 29581463 TI - Engineered 3D vascular and neuronal networks in a microfluidic platform. AB - Neurovascular coupling plays a key role in the pathogenesis of neurodegenerative disorders including motor neuron disease (MND). In vitro models provide an opportunity to understand the pathogenesis of MND, and offer the potential for drug screening. Here, we describe a new 3D microvascular and neuronal network model in a microfluidic platform to investigate interactions between these two systems. Both 3D networks were established by co-culturing human embryonic stem (ES)-derived MN spheroids and endothelial cells (ECs) in microfluidic devices. Co culture with ECs improves neurite elongation and neuronal connectivity as measured by Ca2+ oscillation. This improvement was regulated not only by paracrine signals such as brain-derived neurotrophic factor secreted by ECs but also through direct cell-cell interactions via the delta-notch pathway, promoting neuron differentiation and neuroprotection. Bi-directional signaling was observed in that the neural networks also affected vascular network formation under perfusion culture. This in vitro model could enable investigations of neuro vascular coupling, essential to understanding the pathogenesis of neurodegenerative diseases including MNDs such as amyotrophic lateral sclerosis. PMID- 29581464 TI - Whole-exome Sequencing Helps the Diagnosis and Treatment in Children with Neurodevelopmental Delay Accompanied Unexplained Dyspnea. AB - Neurodevelopmental delay accompanied unexplained dyspnea is a highly lethal disease in clinic. This study is to investigate the performance characteristics of trio whole exome sequencing (Trio-WES) in a pediatric setting by presenting our patient cohort and displaying the diagnostic yield. A total of 31 pediatric patients showing neurodevelopmental delay accompanied unexplained dyspnea were admitted to our hospital and referred for molecular genetic testing using Trio WES. Eight genes namely MMACHC, G6PC, G6PT, ETFDH, OTC, NDUFAF5, SLC22A5, and MAGEL2 were suspected to be responsible for the onset of the clinical symptoms and 6 variants were novel. Standard interpretation according to ACMG guideline showed that the variants were pathogenic. Finally, diagnosis of methylmalonic aciduria and homocystinuria, glycogen storage disease, ornithine transcarbamylase deficiency, glutaric acidemia II, mitochondrial complex 1 deficiency, carnitine deficiency, and Schaaf-Yang syndrome was made in 12 out of the 31 patients. Trio WES is an effective means for molecular diagnosis of infantile neurodevelopmental delay accompanied unexplained dyspnea. As for molecular etiology identification, when routine potential monogenetic inheritance patterns including de novo, autosomal recessive, autosomal dominant, and X-linked recessive inheritance analysis is negative, physicians should take into account imprinted genes. PMID- 29581465 TI - Dietary genistein supplementation for breeders and their offspring improves the growth performance and immune function of broilers. AB - Genistein (GEN) is mainly extracted from soy plants and has potential functions as an antioxidant and in promoting immune function and growth. This study evaluated the effects of feeding breeders and their offspring dietary GEN on the immune function and growth performance of broiler chicks. Breeders were assigned to a control diet or GEN diet (control diet +400 mg/kg GEN), and their offspring were fed a control diet or GEN diet (control diet +40 mg/kg GEN). GEN treatment increased the body weight gain, tibial length, tibial width and slaughter performance of broilers and decreased the feed conversion ratio. The treatment also affected skeletal muscle myosin assembly and growth and increased growth hormone levels and IGF-I and IGFBP1 expression. Following GEN treatment, antigen processing and presentation, macrophage activation, B lymphocyte, NK cell and helper T cell proliferation, and CD4+ T lymphocyte differentiation all increased significantly. Increases were also observed in IgM and IgG concentrations, antibody titers, and antioxidant capacity. In addition, GEN treatment activated the Toll-like receptor signaling pathway and MAPK cascade signaling pathway. In summary, dietary GEN supplementation for breeders and their offspring can improve the growth performance and immune function of broiler chicks. PMID- 29581466 TI - A band of bound states in the continuum induced by disorder. AB - Bound states in the continuum usually refer to the phenomenon of a single or a few discrete bound states embedded in a continuous spectrum of extended states. Here we propose a simple mechanism to achieve a band of bound states in the continuum in a class of disordered quasi-1D and quasi-2D systems, where the bound states and extended states overlap completely in a spectral range. The systems are partially disordered in a way that a band of extended states always exists, not affected by the randomness, whereas the states in all other bands become localized and cover the entire spectrum of extended states. We demonstrate such disordered-induced bound states in the continuum in disordered multi-chain and multi-layer systems. PMID- 29581467 TI - Extracting biological age from biomedical data via deep learning: too much of a good thing? AB - Age-related physiological changes in humans are linearly associated with age. Naturally, linear combinations of physiological measures trained to estimate chronological age have recently emerged as a practical way to quantify aging in the form of biological age. In this work, we used one-week long physical activity records from a 2003-2006 National Health and Nutrition Examination Survey (NHANES) to compare three increasingly accurate biological age models: the unsupervised Principal Components Analysis (PCA) score, a multivariate linear regression, and a state-of-the-art deep convolutional neural network (CNN). We found that the supervised approaches produce better chronological age estimations at the expense of a loss of the association between the aging acceleration and all-cause mortality. Consequently, we turned to the NHANES death register directly and introduced a novel way to train parametric proportional hazards models suitable for out-of-the-box implementation with any modern machine learning software. As a demonstration, we produced a separate deep CNN for mortality risks prediction that outperformed any of the biological age or a simple linear proportional hazards model. Altogether, our findings demonstrate the emerging potential of combined wearable sensors and deep learning technologies for applications involving continuous health risk monitoring and real-time feedback to patients and care providers. PMID- 29581469 TI - Comparative transcriptomics gives insights into the evolution of parasitism in Strongyloides nematodes at the genus, subclade and species level. AB - Strongyloides spp., gastrointestinal nematode parasites of humans and other animals, have genetically identical parasitic and free-living adult life cycle stages. This is an almost unique feature amongst nematodes and comparison of these two stages can provide insights into the genetic basis and evolution of Strongyloides nematode parasitism. Here, we present RNAseq data for S. venezuelensis, a parasite of rodents, and identify genes that are differentially expressed in parasitic and free-living life cycle stages. Comparison of these data with analogous RNAseq data for three other Strongyloides spp., has identified key protein-coding gene families with a putative role in parasitism including WAGO-like Argonautes (at the genus level) and speckle-type POZ-like coding genes (S. venezuelensis-S. papillosus phylogenetic subclade level). Diverse gene families are uniquely upregulated in the parasitic stage of all four Strongyloides species, including a distinct upregulation of genes encoding cytochrome P450 in S. venezuelensis, suggesting some diversification of the molecular tools used in the parasitic life cycle stage among individual species. Together, our results identify key gene families with a putative role in Strongyloides parasitism or features of the parasitic life cycle stage, and deepen our understanding of parasitism evolution among Strongyloides species. PMID- 29581468 TI - Long term potentiation, but not depression, in interlamellar hippocampus CA1. AB - Synaptic plasticity in the lamellar CA3 to CA1 circuitry has been extensively studied while interlamellar CA1 to CA1 connections have not yet received much attention. One of our earlier studies demonstrated that axons of CA1 pyramidal neurons project to neighboring CA1 neurons, implicating information transfer along a longitudinal interlamellar network. Still, it remains unclear whether long-term synaptic plasticity is present within this longitudinal CA1 network. Here, we investigate long-term synaptic plasticity between CA1 pyramidal cells, using in vitro and in vivo extracellular recordings and 3D holography glutamate uncaging. We found that the CA1-CA1 network exhibits NMDA receptor-dependent long term potentiation (LTP) without direction or layer selectivity. By contrast, we find no significant long-term depression (LTD) under various LTD induction protocols. These results implicate unique synaptic properties in the longitudinal projection suggesting that the interlamellar CA1 network could be a promising structure for hippocampus-related information processing and brain diseases. PMID- 29581470 TI - Factors associated with cognitive impairment in elderly versus nonelderly patients with metabolic syndrome: the different roles of FGF21. AB - Increased fibroblast growth factor 21 (FGF21) levels have been found in patients with metabolic syndrome (MetS). MetS is also associated with cognitive decline. However, the correlation between FGF21 and cognitive decline in elderly and nonelderly MetS patients has not been investigated. 116 non-elderly patients (age <65 years old) and 96 elderly patients (>=65 years old) with MetS were enrolled. Blood samples for FGF21 were collected from all participants after 12-hour fasting. Cognitive function was assessed using the Montreal cognitive assessment (MoCA) test. The MoCA score was negatively associated with age and was different among different levels of education in these MetS patients. In the non-elderly group, body mass index (BMI) showed positively correlated with MoCA score while, FGF21 level and HbA1C were negatively associated with the MoCA score in non elderly MetS patients. BMI was the only factor which showed a negative correlation with the MoCA score in elderly MetS patients. This study demonstrated that FGF21 level was independently associated with cognitive impairment in non elderly patients but not in elderly patients. The possible role of FGF21 level in cognitive impairment in non-elderly should be confirmed in a prospective study. PMID- 29581471 TI - Using spatial mark-recapture for conservation monitoring of grizzly bear populations in Alberta. AB - One of the challenges in conservation is determining patterns and responses in population density and distribution as it relates to habitat and changes in anthropogenic activities. We applied spatially explicit capture recapture (SECR) methods, combined with density surface modelling from five grizzly bear (Ursus arctos) management areas (BMAs) in Alberta, Canada, to assess SECR methods and to explore factors influencing bear distribution. Here we used models of grizzly bear habitat and mortality risk to test local density associations using density surface modelling. Results demonstrated BMA-specific factors influenced density, as well as the effects of habitat and topography on detections and movements of bears. Estimates from SECR were similar to those from closed population models and telemetry data, but with similar or higher levels of precision. Habitat was most associated with areas of higher bear density in the north, whereas mortality risk was most associated (negatively) with density of bears in the south. Comparisons of the distribution of mortality risk and habitat revealed differences by BMA that in turn influenced local abundance of bears. Combining SECR methods with density surface modelling increases the resolution of mark recapture methods by directly inferring the effect of spatial factors on regulating local densities of animals. PMID- 29581472 TI - Proteomic analysis of plasma extracellular vesicles reveals mitochondrial stress upon HTLV-1 infection. AB - Extracellular vesicles (EVs) can participate in intercellular communication and pathogenesis. EVs contain many cargos, including proteins, and the composition of EVs differs between cell-types and activation levels. Thus, plasma EVs can be used as a biomarker of systemic response to infection and/or disease progression. In this study, we aimed at describing alterations in the protein content of plasma EVs upon infection with the human T-lymphotropic retrovirus type 1 (HTLV 1). HTLV-1 is the etiological agent of a lymphoproliferative disease (ATL) and a series of inflammatory diseases, including a neurodegenerative inflammatory disease (HAM/TSP). We found that plasma EVs are more abundant and smaller in HTLV 1 asymptomatic carriers or HAM/TSP patients when compared to uninfected healthy donors. Moreover, EVs from HTLV-1 infected donors contain markers of metabolic and mitochondrial stress. PMID- 29581473 TI - Revealing Individual Lifestyles through Mass Spectrometry Imaging of Chemical Compounds in Fingerprints. AB - Fingerprints, specifically the ridge details within the print, have long been used in forensic investigations for individual identification. Beyond the ridge detail, fingerprints contain useful chemical information. The study of fingerprint chemical information has become of interest, especially with mass spectrometry imaging technologies. Mass spectrometry imaging visualizes the spatial relationship of each compound detected, allowing ridge detail and chemical information in a single analysis. In this work, a range of exogenous fingerprint compounds that may reveal a personal lifestyle were studied using matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI). Studied chemical compounds include various brands of bug sprays and sunscreens, as well as food oils, alcohols, and citrus fruits. Brand differentiation and source determination were possible based on the active ingredients or exclusive compounds left in fingerprints. Tandem mass spectrometry was performed for the key compounds, so that these compounds could be confidently identified in a single multiplex mass spectrometry imaging data acquisition. PMID- 29581474 TI - Furin inhibitor protects against neuronal cell death induced by activated NMDA receptors. AB - The proprotein convertases (PCs) act as serine proteases and are known to convert diverse precursor proteins into their active forms. Among the PCs, furin has been considered to play a crucial role not only in embryogenesis, but also in the initiation and progression of certain pathologic conditions. However, the roles played by furin with respect to neuronal cell injuries remain to be determined. An excessive influx of Ca2+ through the N-methyl-d-aspartate (NMDA) receptor has been associated with diverse neurological and neurodegenerative disorders. The aim of this study was to achieve further insight into the pathophysiologic roles of furin in cultured cortical neurons. We demonstrated that furin inhibitors dose dependently prevented neuronal injury induced by NMDA treatment. Neuronal injury induced by NMDA treatment was attenuated by the calpain inhibitor calpeptin. And the increase observed in the activity of calpain after NMDA treatment was significantly inhibited by these furin inhibitors. Furthermore, calpain-2 activity, which was evaluated by means of the immunoblotting assay, was increased by NMDA treatment. It was noteworthy that this increased activity was almost completely inhibited by a furin inhibitor. Our findings suggested that furin is involved in NMDA-induced neuronal injury by acting upstream of calpain.

AB - We propose Josephson junction with a high-spin magnetic impurity sandwiched between two superconductors. This system shows a pi junction behavior as a function of the spin magnetic moment state of the impurity, the interface transparency, exchange coupling and electron-electron interactions in the system. The system is theoretically analyzed for possible reason behind the pi shift. The crucial role of spin flip scattering is highlighted. Possible applications in quantum computation of our proposed tunable high spin magnetic impurity pi junction is underscored. PMID- 29581476 TI - Dynamic Evolution of alpha-Gliadin Prolamin Gene Family in Homeologous Genomes of Hexaploid Wheat. AB - Wheat Gli-2 loci encode complex groups of alpha-gliadin prolamins that are important for breadmaking, but also major triggers of celiac disease (CD). Elucidation of alpha-gliadin evolution provides knowledge to produce wheat with better end-use properties and reduced immunogenic potential. The Gli-2 loci contain a large number of tandemly duplicated genes and highly repetitive DNA, making sequence assembly of their genomic regions challenging. Here, we constructed high-quality sequences spanning the three wheat homeologous alpha gliadin loci by aligning PacBio-based sequence contigs with BioNano genome maps. A total of 47 alpha-gliadin genes were identified with only 26 encoding intact full-length protein products. Analyses of alpha-gliadin loci and phylogenetic tree reconstruction indicate significant duplications of alpha-gliadin genes in the last ~2.5 million years after the divergence of the A, B and D genomes, supporting its rapid lineage-independent expansion in different Triticeae genomes. We showed that dramatic divergence in expression of alpha-gliadin genes could not be attributed to sequence variations in the promoter regions. The study also provided insights into the evolution of CD epitopes and identified a single indel event in the hexaploid wheat D genome that likely resulted in the generation of the highly toxic 33-mer CD epitope. PMID- 29581477 TI - Metal behavior in the extremes of dynamics. AB - When the rate of loading is faster than the rate at which material absorbs and converts energy to plastic work and damages, then there is an excess of energy that is partly stored in the material's microstructure and the rest of it triggers micro-dynamic excitations. The additional storage necessitates the development of plastic flow constraints and is directly responsible for the observed dynamic strengthening. At extreme conditions, we find that the micro excitations contribute to the dynamic behavior. The phenomena are universally observed in metals, frictional materials and polymers. In essence, strong dynamics creates conditions at which materials are pushed from equilibrium and temporarily reside in an excited state of behavior. This study is focused on the behavior of metals. The concept is incorporated into a mechanisms-based constitutive model and is examined for annealed OFHC copper. PMID- 29581479 TI - Effects of Structural and Energetic Disorders on Charge Transports in Crystal and Amorphous Organic Layers. AB - Understanding charge transports in organic films is important for both fundamental science and practical applications. Here, contributions of off diagonal (structural) and diagonal (energetic) disorders to charge transports were clarified using molecular-based multiscale simulation. These disorders, important for understanding charge transport in organic systems, are investigated by comparing crystal and amorphous aggregates of N,N'-diphenyl-N,N'-bis(1 naphthyl)-1,1'-biphenyl-4,4'-diamine (NPD). Although NPD has been used as a hole transport material, it also exhibits comparable electron mobility experimentally. The experimental mobility and its electric field dependence in amorphous layers were reasonably reproduced by the multiscale simulation, confirming the electron transport properties of NPD. We assumed that the structural disorder would lower mobilities; however, the mobilities were found to be independent of the degree of structural disorder. Energetic disorder markedly lowered charge mobility instead. Charge migration in crystals was dominated by maximum electronic coupling pairs, whereas small electronic coupling pairs significantly contributed to charge transport in amorphous aggregate. PMID- 29581478 TI - Heparanase attenuates axon degeneration following sciatic nerve transection. AB - Axon degeneration underlies many nervous system diseases; therefore understanding the regulatory signalling pathways is fundamental to identifying potential therapeutics. Previously, we demonstrated heparan sulphates (HS) as a potentially new target for promoting CNS repair. HS modulate cell signalling by both acting as cofactors in the formation of ligand-receptor complexes and in sequestering ligands in the extracellular matrix. The enzyme heparanase (Hpse) negatively regulates these processes by cleaving HS and releasing the attached proteins, thereby attenuating their ligand-receptor interaction. To explore a comparative role for HS in PNS axon injury/repair we data mined published microarrays from distal sciatic nerve injury. We identified Hpse as a previously unexplored candidate, being up-regulated following injury. We confirmed these results and demonstrated inhibition of Hpse led to an acceleration of axonal degeneration, accompanied by an increase in beta-catenin. Inhibition of beta-catenin and the addition of Heparinase I both attenuated axonal degeneration. Furthermore the inhibition of Hpse positively regulates transcription of genes associated with peripheral neuropathies and Schwann cell de-differentiation. Thus, we propose Hpse participates in the regulation of the Schwann cell injury response and axo glia support, in part via the regulation of Schwann cell de-differentiation and is a potential therapeutic that warrants further investigation. PMID- 29581480 TI - Late cardiovascular morbidity and mortality following pediatric allogeneic hematopoietic cell transplantation. AB - We analyzed late cardiovascular outcomes of 661 patients who survived at least 2 years from hematopoietic cell transplantation for childhood hematologic malignancy between 1995 and 2008. Center for International Blood and Marrow Transplant Research data was supplemented with surveys focused on cardiotoxicity and potential risk factors. The median duration of follow-up was 97 months (range 24-230). 4.2% of survivors experienced at least one of the primary outcomes including coronary artery disease (0.2%), cerebrovascular accident (0.6%), cardiomyopathy (3%), and cardiac-related death (0.5%). Patients who received anthracycline chemotherapy (HR 4.67, p = 0.036) or cranial or chest radiation (HR 5.58, p < 0.0001; HR 2.18, p = 0.0087) were at increased risk for developing one of the primary outcomes. Dyslipidemia was diagnosed in 18% of survivors. Pre transplant anthracycline (HR 1.74, p < 0.0001) and chest radiation (HR 1.34, p = 0.0371) were risk factors for dyslipidemia. Overweight/obese body mass status was present in 63% of patients at baseline, 65% at 2 years, and 52% at most recent evaluation. Diabetes was diagnosed in 7% of subjects. In conclusion, severe cardiovascular complications were infrequently reported. The incidence of risk factors including obesity and dyslipidemia were significant and will likely increase the risk of cardiovascular disease over time in transplant survivors. PMID- 29581481 TI - Linked homozygous BMPR1B and PDHA2 variants in a consanguineous family with complex digit malformation and male infertility. AB - In affected members of a consanguineous family, a syndrome, which is concurrence of set of medical signs, is often observed and commonly assumed to have arisen from pleiotropy, i.e., the phenomenon of a single gene variant affecting multiple traits. We detected six sibs afflicted with a unique combination of digit malformation that includes brachydactyly, symphalangism and zygodactyly plus infertility in males owing to azoospermia, sperm immotility or necrospermia, which we hypothesised to have arisen from a defect in a single gene. We mapped the disease locus and by exome sequencing identified in patients homozygous missense variants bone morphogenetic protein receptor type IB (BMPR1B) c.640C>T (p.(Arg214Cys)) and alpha-2 pyruvate dehydrogenase (PDHA2) c.679A>G (p.(Met227Val)). Structural protein modelling, protein sequence conservation and in silico analysis indicate that both variants affect protein function. BMPR1B is known to be responsible for autosomal dominant brachydactyly and autosomal recessive acromesomelic chondrodysplasia. Our findings show that also recessive complex digit malformation can be caused by BMPR1B variant and not all biallelic BMPR1B variants cause acromesomelic dysplasia. PDHA2 is a novel candidate gene for male infertility; the protein product is a mitochondrial enzyme with highest expression in ejaculated sperm. Our findings are a unique example of two linked variants, ~ 711 Kb apart, in different genes that together manifest as a novel syndrome. They demonstrate that exome sequencing and not candidate gene approach should be employed in disease gene hunt, defining new diseases and genetic testing, to rule out the coincidental presence of two variants contributing together to the phenotype, which may be discerned as a novel disease. PMID- 29581482 TI - Higher High-Sensitivity C Reactive Protein is Associated with Future Premature Ventricular Contraction: a Community Based Prospective Cohort Study. AB - We aimed to determine whether hs-CRP is a predictor of future premature ventricular contraction (PVC) events in a community based population. A total of 101,510 participants were recruited at baseline (2006-2007). The follow-up visits were conducted every two years. Participants who were free from PVC at baseline and achieved the fourth visit, or diagnosed of PVC during the subsequent visits were included for analyses. Diagnosis of PVC was based on standard supine resting, 10-s 12-lead ECG. Cox regression was applied to evaluate the association between quartiles of hs-CRP and the incidence of PVCs. 60710 participants (male: 79.9%, mean age 49.4 years) were included for analyses. During a mean follow-up of 74.9 +/- 7.4 months, 908 (1.5%) participants were diagnosed with PVC. Participants of the highest quartile of hs-CRP had significantly increased risk of PVC events as compared with the lowest quartile (HR 1.36; 95% CI 1.12-1.66); and stratified analyses showed similar result in males (HR 1.45; 95% CI 1.16 1.80), but not in females (HR 1.12; 95% CI 0.71-1.79). Moreover, elevated serum hs-CRP was associated with future PVC in participants without history of myocardial infarction or stroke (HR 1.34; 95% CI 1.09-1.65). Elevated hs-CRP was an independent predictor of PVC in Chinese population, especially in men. PMID- 29581483 TI - Height and overall cancer risk and mortality: evidence from a Mendelian randomisation study on 310,000 UK Biobank participants. AB - BACKGROUND: Observational studies have shown that being taller is associated with greater cancer risk. However, the interpretation of such studies can be hampered by important issues such as confounding and reporting bias. METHODS: We used the UK Biobank resource to develop genetic predictors of height and applied these in a Mendelian randomisation framework to estimate the causal relationship between height and cancer. Up to 438,870 UK Biobank participants were considered in our analysis. We addressed two primary cancer outcomes, cancer incidence by age ~60 and cancer mortality by age ~60 (where age ~60 is the typical age of UK Biobank participants). RESULTS: We found that each genetically predicted 9 cm increase in height conferred an odds ratio of 1.10 (95% confidence interval 1.07-1.13) and 1.09 (1.02-1.16) for diagnosis of any cancer and death from any cancer, respectively. For both risk and mortality, the effect was larger in females than in males. CONCLUSIONS: Height increases the risk of being diagnosed with and dying from cancer. These findings from Mendelian randomisation analyses agree with observational studies and provide evidence that they were not likely to have been strongly affected by confounding or reporting bias. PMID- 29581485 TI - Cooperative communication within and between single nanocatalysts. AB - Enzymes often show catalytic allostery in which reactions occurring at different sites communicate cooperatively over distances of up to a few nanometres. Whether such effects can occur with non-biological nanocatalysts remains unclear, even though these nanocatalysts can undergo restructuring and molecules can diffuse over catalyst surfaces. Here we report that phenomenologically similar, but mechanistically distinct, cooperative effects indeed exist for nanocatalysts. Using spatiotemporally resolved single-molecule catalysis imaging, we find that catalytic reactions on a single Pd or Au nanocatalyst can communicate with each other, probably via hopping of positively charged holes on the catalyst surface, over ~102 nanometres and with a temporal memory of ~101 to 102 seconds, giving rise to positive cooperativity among its surface active sites. Similar communication is also observed between individual nanocatalysts, however it operates via a molecular diffusion mechanism involving negatively charged product molecules, and its communication distance is many micrometres. Generalization of these long-range intra- and interparticle catalytic communication mechanisms may introduce a novel conceptual framework for understanding nanoscale catalysis.

AB - The sequenced Diels-Alder/oxidation reaction represents a powerful route for the construction of aromatic compounds in organic synthesis. The oxidative Diels Alder reaction with H2 evolution would be a more ideal approach that can avoid the additional oxidation procedure and stoichiometric oxidant. Herein, an oxidative [4 + 2] annulation reaction of styrene derivatives with electron-rich dienophiles accompanying the H2 generation has been developed by using the synergistic merger of photoredox and cobaloxime catalyst. With respect to atom and step-economy ideals, this dual catalytic system enables the formation of high value molecules from feedstock chemicals in a single step under room temperature. PMID- 29581486 TI - Distinct thermodynamic signatures of oligomer generation in the aggregation of the amyloid-beta peptide. AB - Mapping free-energy landscapes has proved to be a powerful tool for studying reaction mechanisms. Many complex biomolecular assembly processes, however, have remained challenging to access using this approach, including the aggregation of peptides and proteins into amyloid fibrils implicated in a range of disorders. Here, we generalize the strategy used to probe free-energy landscapes in protein folding to determine the activation energies and entropies that characterize each of the molecular steps in the aggregation of the amyloid-beta peptide (Abeta42), which is associated with Alzheimer's disease. Our results reveal that interactions between monomeric Abeta42 and amyloid fibrils during fibril dependent secondary nucleation fundamentally reverse the thermodynamic signature of this process relative to primary nucleation, even though both processes generate aggregates from soluble peptides. By mapping the energetic and entropic contributions along the reaction trajectories, we show that the catalytic efficiency of Abeta42 fibril surfaces results from the enthalpic stabilization of adsorbing peptides in conformations amenable to nucleation, resulting in a dramatic lowering of the activation energy for nucleation. PMID- 29581488 TI - Infused ice can multiply IceCube's sensitivity. AB - The IceCube Neutrino Observatory is the world's largest neutrino detector with a cubic-kilometer instrumented volume at the South Pole. It is preparing for a major upgrade that will significantly increase its sensitivity. A promising technological innovation investigated for this upgrade is wavelength shifting optics. Augmenting sensors with such optics could increase the photo-collection area of IceCube's digital optical modules, and shift the incoming photons' wavelength to where these modules are the most sensitive. Here we investigate the use of IceCube's drill holes as wavelength shifting optics. We calculate the sensitivity enhancement due to increasing the ice's refractive index in the holes, and infusing wavelength-shifting substrate into the ice. We find that, with adequate wavelength-shifter infusion, every ~0.05 increase in the ice's refractive index will increase IceCube's photon sensitivity by 100%, opening the possibility for the substantial, cost-effective expansion of IceCube's reach.

PMID- 29581487 TI - A prominent air pollutant, Indeno[1,2,3-cd]pyrene, enhances allergic lung inflammation via aryl hydrocarbon receptor. AB - Chronic exposure to ambient polycyclic aromatic hydrocarbons (PAHs) is associated with asthma, but its regulatory mechanisms remain incompletely defined. We report herein that elevated levels of urinary 1-hydroxypyrene, a biomarker of PAH exposure, were found in asthmatic subjects (n = 39) as compared to those in healthy subjects (n = 43) living in an industrial city of Taiwan, where indeno[1,2,3-cd]pyrene (IP) was found to be a prominent PAH associated with ambient PM2.5. In a mouse model, intranasal exposure of mice with varying doses of IP significantly enhanced antigen-induced allergic inflammation, including increased airway eosinophilia, Th2 cytokines, including IL-4 and IL-5, as well as antigen-specific IgE level, which was absent in dendritic cell (DC)-specific aryl hydrocarbon receptor (AhR)-null mice. Mechanistically, IP treatment significantly altered DC's function, including increased level of pro-inflammatory IL-6 and decreased generation of anti-inflammatory IL-10. The IP's effect was lost in DCs from mice carrying an AhR-mutant allele. Taken together, these results suggest that chronic exposure to environmental PAHs may pose a significant risk for asthma, in which IP, a prominent ambient PAH in Taiwan, was shown to enhance the severity of allergic lung inflammation in mice through, at least in part, its ability in modulating DC's function in an AhR-dependent manner.

PMID- 29581509 TI - The RNA-binding protein ARPP21 controls dendritic branching by functionally opposing the miRNA it hosts. AB - About half of mammalian miRNA genes lie within introns of protein-coding genes, yet little is known about functional interactions between miRNAs and their host genes. The intronic miRNA miR-128 regulates neuronal excitability and dendritic morphology of principal neurons during mouse cerebral cortex development. Its conserved host genes, R3hdm1 and Arpp21, are predicted RNA-binding proteins. Here we use iCLIP to characterize ARPP21 recognition of uridine-rich sequences with high specificity for 3'UTRs. ARPP21 antagonizes miR-128 activity by co-regulating a subset of miR-128 target mRNAs enriched for neurodevelopmental functions. Protein-protein interaction data and functional assays suggest that ARPP21 acts as a positive post-transcriptional regulator by interacting with the translation initiation complex eIF4F. This molecular antagonism is reflected in inverse activities during dendritogenesis: miR-128 overexpression or knockdown of ARPP21 reduces dendritic complexity; ectopic ARPP21 leads to an increase. Thus, we describe a unique example of convergent function by two products of a single gene. PMID- 29581512 TI - Learning from CIK plants. PMID- 29581511 TI - A group of receptor kinases are essential for CLAVATA signalling to maintain stem cell homeostasis. AB - Continuous organ initiation and outgrowth in plants relies on the proliferation and differentiation of stem cells maintained by the CLAVATA (CLV)-WUSCHEL (WUS) negative-feedback loop1-3. Leucine-rich repeat receptor-like protein kinases (LRR RLKs), including CLV1, BARELY ANY MERISTEMS and RECEPTOR-LIKE PROTEIN KINASE 2 (RPK2), a receptor-like protein CLV2 and a pseudokinase CORYNE (CRN) are involved in the perception of the CLV3 signal to repress WUS expression4-10. WUS, a homeodomain transcription factor, in turn directly activates CLV3 expression and promotes stem cell activity in the shoot apical meristem11,12. However, the signalling mechanism immediately following the perception of CLV3 by its receptors is poorly understood. Here, we show that a group of LRR-RLKs, designated as CLAVATA3 INSENSITIVE RECEPTOR KINASES (CIKs), have essential roles in regulating CLV3-mediated stem cell homeostasis. The cik1 2 3 4 quadruple mutant exhibits a significantly enlarged SAM, resembling clv mutants. Genetic analyses and biochemical assays demonstrated that CIKs function as co-receptors of CLV1, CLV2/CRN and RPK2 to mediate CLV3 signalling through phosphorylation. Our findings not only widen the understanding of the underlying mechanism of CLV3 signal transduction in regulating stem cell fate but also reveal a novel group of RLKs that function as co-receptors to possibly mediate multiple extrinsic and intrinsic signals during plant growth and development. PMID- 29581513 TI - The CPLANE protein Intu protects kidneys from ischemia-reperfusion injury by targeting STAT1 for degradation. AB - Intu is known as a ciliogenesis and planar polarity effector (CPLANE) protein. Although roles for Intu have been reported during embryonic development and in the context of developmental disorders, its function and regulation in adult tissues remain poorly understood. Here we show that ablation of Intu specifically in kidney proximal tubules aggravates renal ischemia-reperfusion injury, and leads to defective post-injury ciliogenesis. We identify signal transducer and activator of transcription 1 (STAT1) as a novel interacting partner of Intu. In vitro, Intu and STAT1 colocalize at the centriole/basal body area, and Intu promotes proteasomal degradation of STAT1. During cell stress, Intu expression preserves cilia length and cell viability, and these actions are antagonized by STAT1 expression. Thus, we propose a role for Intu in protecting cells and tissues after injury by targeting STAT1 for degradation and maintaining primary cilia. PMID- 29581514 TI - Structure and Dynamics of Polymeric Canopies in Nanoscale Ionic Materials: An Electrical Double Layer Perspective. AB - Nanoscale ionic materials (NIMs) are an emerging class of materials consisting of charged nanoparticles and polymeric canopies attaching to them dynamically by electrostatic interactions. Using molecular simulations, we examine the structure and dynamics of the polymeric canopies in model NIMs in which the canopy thickness is much smaller than the nanoparticle diameter. Without added electrolyte ions, the charged terminal groups of polymers adsorb strongly on charged walls, thereby electrostatically "grafting" polymers to the wall. These polymers are highly stretched. They rarely desorb from the wall, but maintain modest in-plane mobility. When electrolyte ion pairs are introduced, the counterions adsorb on the wall, causing some electrostatically "grafted" polymers to desorb. The desorbed polymers, however, are less than the adsorbed counter ions, which leads to an overscreening of wall charges. The desorbed polymers' charged terminal groups do not distribute uniformly across the canopy but are depleted in some regions; they adopt conformation similar to those in bulk and exchange with the "grafted" polymers rapidly, hence dilating the canopy and accelerating its dynamics. We understand these results by taking the canopy as an electrical double layer, and highlight the importance of the interplay of electrostatic and entropic effects in determining its structure and dynamics. PMID- 29581515 TI - Mentha-Stabilized Silver Nanoparticles for High-Performance Colorimetric Detection of Al(III) in Aqueous Systems. AB - The present paper reports a facile and selective colorimetric method for the detection of potential environmental and health hazardous metal ions using green synthesized silver nanoparticles (AgNPs). Here the organic functional groups present in the plant extract (Mentha arvensis) are used as reductants and stabilizers in the synthesis of AgNPs. They also provide a suitable binding site to the (Al(III)) analyte in the detection mechanism. The leaf extract of Mentha arvensis was used to synthesize AgNPs at room-temperature and at 80 degrees C. The AgNPs synthesized at 80 degrees C exhibit excellent selective colorimetric detection of Al(III). The as-synthesized AgNPs have been characterized, and the synthesis, stabilization of NPs and detection mechanism has also been illustrated by using UV-vis, XPS, FTIR, TEM, EDX, SEM, AAS, and TGA analytical tools and techniques. The selectivity of detection probe was supported by the reaction between probe and metal ions followed first-order kinetics having the highest value of the regression coefficient (R2 = 0.99) for Al(III) and the analysis of thermodynamic parameters. The prepared sensor showed a lower limit of detection (LOD) of 1 nM (S/N = 3.2) in real water samples. The proposed method can be successfully utilized for the detection of Al(III) from both drinking and real water samples at the nanomolar level.

AB - Phytophthora capsici is a devastating oomycete that affects solanaceous, cucurbitaceous, fabaceous, and other crops in the United States (US) and worldwide. The release of the P. capsici genome allows for design of robust markers for genetic studies. We identified and characterized microsatellites in the P. capsici transcriptome. A subset of 50 microsatellites were assayed in a diverse set of P. capsici isolates and evaluated for polymorphism. Polymorphic microsatellites were confirmed by fragment analysis, and 12 were used for population characterization of 50 P. capsici isolates from different states, hosts, and mating types. Analysis of genetic relationship among isolates revealed significant geographic structure by state. Our findings highlight the usefulness of these 12 microsatellites to characterize the population structure of P. capsici and potential transferability to closely-related Phytophthora spp. since markers are located in coding regions. Our markers will facilitate genetic characterization and complement phenotypic studies of P. capsici populations, which may assist in deployment of disease management strategies.

AB - Elia Kazan's 1963 film, America America is a tribute to the immigrant experience of his own forebears, and has relevance to the refugee crisis of today. In stark black and white cinematography, the film provides insight into the refugee immigrant experience, personified in Stavros, a young man longing for freedom, obsessed with an idealized America. His hope and innocence cannot safeguard him. His memories of his happy childhood and loving family create idealizing transferences to a world of others who manipulate and betray him as he undertakes his quest. Eventually he too learns to manipulate and betray, unconsciously identifying with the aggressor. History will offer ethical challenges, the black and white cinematography mirroring the black and white perception of good and bad, the shades of grey evoking a maturation of understanding. PMID- 29581518 TI - Depressive mood in individuals with spinal cord injury (SCI) living in Greece. AB - STUDY DESIGN: Cross-sectional study. OBJECTIVES: To provide data on depressive symptoms rates in the Greek SCI population and to investigate their association with demographic and clinical variables. SETTING: Greek territory. METHODS: One hundred and sixty-four individuals with SCI living in the community for at least 1 year after the completion of the primary inpatient rehabilitation program were included in the study. Our group of participants were enrolled from multiple rehabilitation centers throughout Greece and were evaluated for probable depression according to the Patient Health Questionnaire (PHQ-9). Univariable and multiple linear regression analyses were performed to assess the possible association of risk factors with the occurrence of depression. We had also examined the correlation between PHQ-9 and scales measuring social reintegration (Craig Handicap Assessment and Reporting Technique (CHART)), quality of life (World Health Organization Quality of Life BREF (WHOQOL-BREF)), and independence (Spinal Cord Independence Measure (SCIM)). RESULTS: It was found that 18.2% of the sample had probable depression. The mean (SD) PHQ-9 score was 5.7 (4.9). The multiple linear regression analysis showed that high pain scores (P = 0.001) and suffering from both nociceptive and neuropathic pain (P = 0.005) were associated with depressive mood, while pressure ulcers had a significant effect (P = 0.049) only in the univariable analysis. Participant's PHQ-9 scores had also a negative correlation with almost all CHART, WHOQOL-BREF, and SCIM subscales' scores. CONCLUSIONS: This study documents relatively low rates of probable depression among individuals with SCI in Greece. Severe pain and pressure ulcers were the main identified predictors of depressive mood. PMID- 29581519 TI - Internet-delivered mindfulness for people with depression and chronic pain following spinal cord injury: a randomized, controlled feasibility trial. AB - STUDY DESIGN: Between-subjects, randomized controlled feasibility study. OBJECTIVES: Populations with reduced sensory and motor function are at increased risk of depression, anxiety and pain, and may be less geographically mobile. This study explored the efficacy and feasibility of web-based mindfulness training for people with spinal cord injury (SCI). SETTING: UK community sample. METHODS: Participants were randomly allocated to an 8-week online mindfulness intervention (N = 36), or to internet-delivered psychoeducation (N = 31). Depression symptom severity was the primary outcome. Secondary outcomes included anxiety, quality of life (QoL), pain perception, pain catastrophizing and mindfulness. Measures were taken before (T1), at completion of, (T2), and 3 months following the intervention (T3). RESULTS: At T2, ten participants discontinued mindfulness training, and five discontinued psychoeducation. Dropouts were of significantly older age. Nine participants were lost to follow-up. Mindfulness reduced depression significantly more than psychoeducation at T2 (mean difference = 1.50, 95% CI [-2.43, -0.58]) and T3 (mean difference = -2.34, 95% CI [-3.62, 1.10]). Anxiety, pain unpleasantness and catastrophizing were significantly reduced compared with psychoeducation. Total mindfulness scores, and all facets of mindfulness except observing were significantly higher following mindfulness training. At follow-up, reductions in anxiety and catastrophizing persisted. CONCLUSIONS: Internet-delivered mindfulness training offers unique benefits and is viable for people with reduced sensory awareness. Future work should explore the feasibility of combined education and mindfulness training. The use of brief interventions shows promise in maximizing participant retention. PMID- 29581520 TI - Predicting Urban Reservoir Levels Using Statistical Learning Techniques. AB - Urban water supplies are critical to the growth of the city and the wellbeing of its citizens. However, these supplies can be vulnerable to hydrological extremes, such as droughts and floods, especially if they are the main source of water for the city. Maintaining these supplies and preparing for future conditions is a crucial task for water managers, but predicting hydrological extremes is a challenge. This study tested the abilities of eight statistical learning techniques to predict reservoir levels, given the current hydroclimatic conditions, and provide inferences on the key predictors of reservoir levels. The results showed that random forest, an ensemble, tree-based method, was the best algorithm for predicting reservoir levels. We initially developed the models using Lake Sidney Lanier (Atlanta, Georgia) as the test site; however, further analysis demonstrated that the model based on the random forest algorithm was transferable to other reservoirs, specifically Eagle Creek (Indianapolis, Indiana) and Lake Travis (Austin, Texas). Additionally, we found that although each reservoir was impacted differently, streamflow, city population, and El Nino/Southern Oscillation (ENSO) index were repeatedly among the most important predictors. These are critical variables which can be used by water managers to recognize the potential for reservoir level changes. PMID- 29581521 TI - The effects of host species and sexual dimorphism differ among root, leaf and flower microbiomes of wild strawberries in situ. AB - Plant-associated microbiomes profoundly influence host interactions with below- and aboveground environments. Characterizing plant-associated microbiomes in experimental settings have revealed important drivers of microbiota assemblies within host species. However, it remains unclear how important these individual drivers (e.g., organ type, host species, host sexual phenotype) are in structuring the patterns of plant-microbiota association in the wild. Using 16s rRNA sequencing, we characterized root, leaf and flower microbiomes in three closely related, sexually polymorphic Fragaria species, in the broadly sympatric portion of their native ranges in Oregon, USA. Taking into account the potential influence of broad-scale abiotic environments, we found that organ type explained the largest variation of compositional and phylogenetic alpha- and beta-diversity of bacterial communities in these wild populations, and its overall effect exceeded that of host species and host sex. Yet, the influence of host species increased from root to leaf to flower microbiomes. We detected strong sexual dimorphism in flower and leaf microbiomes, especially in host species with the most complete separation of sexes. Our results provide the first demonstration of enhanced influence of host species and sexual dimorphism from root to flower microbiomes, which may be applicable to many other plants in the wild. PMID- 29581522 TI - Relationship between age and surgical success after trabeculectomy with adjunctive mitomycin C. AB - PURPOSE: To investigate whether there is any effect of age on bleb morphology and surgical success after trabeculectomy with adjunctive Mitomycin C (MMC). METHODS: A total 143 eyes of 123 patients were divided into two groups: group 1 ( <= 60 years old, n = 85) and group 2 ( > 60 years old, n = 58). Kaplan-Meier survival curve analysis was used to assess long-term surgical success according to "complete success" (intraocular pressure (IOP) reduction >= 30% without medications) and "qualified success" criteria (IOP reduction >= 30%, with or without medications) between the two groups. Cox proportional hazard models were used to examine the factors associated with surgical success. Bleb morphology was evaluated by height, extent and vascularity at postoperative 1 month, 3 months, 6 months, and 12 months. RESULTS: The younger-age group (group 1) showed significantly better results, in terms of both complete success and qualified success, than did the older-age group (group 2) (p < 0.001 and p = 0.01, respectively). Age and preoperative anti-glaucoma medications were the factors related to complete success (p = 0.001). Also, there were significant differences in height, extent and vascularity of bleb between the two groups (p = 0.038, p = 0.002 and p = 0.006, respectively). CONCLUSION: The long-term surgical outcome after trabeculectomy with MMC was better in the younger-age group than in the older-age group. Specifically, the younger-age group showed a more prominent and more localized bleb with less vascularity.

PMID- 29581524 TI - Exercise Mitigates Alcohol Induced Endoplasmic Reticulum Stress Mediated Cognitive Impairment through ATF6-Herp Signaling. AB - Chronic ethanol/alcohol (AL) dosing causes an elevation in homocysteine (Hcy) levels, which leads to the condition known as Hyperhomocysteinemia (HHcy). HHcy enhances oxidative stress and blood-brain-barrier (BBB) disruption through modulation of endoplasmic reticulum (ER) stress; in part by epigenetic alternation, leading to cognitive impairment. Clinicians have recommended exercise as a therapy; however, its protective effect on cognitive functions has not been fully explored. The present study was designed to observe the protective effects of exercise (EX) against alcohol-induced epigenetic and molecular alterations leading to cerebrovascular dysfunction. Wild-type mice were subjected to AL administration (1.5 g/kg-bw) and subsequent treadmill EX for 12 weeks (5 day/week@7-11 m/min). AL affected mouse brain through increases in oxidative and ER stress markers, SAHH and DNMTs alternation, while decreases in CBS, CSE, MTHFR, tight-junction proteins and cellular H2S levels. Mechanistic study revealed that AL increased epigenetic DNA hypomethylation of Herp promoter. BBB dysfunction and cognitive impairment were observed in the AL treated mice. AL mediated transcriptional changes were abolished by administration of ER stress inhibitor DTT. In conclusion, exercise restored Hcy and H2S to basal levels while ameliorating AL-induced ER stress, diminishing BBB dysfunction and improving cognitive function via ATF6-Herp-signaling. EX showed its protective efficacy against AL-induced neurotoxicity. PMID- 29581525 TI - Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. AB - Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined. The Innate immune system can be activated by endogenous nucleic acids from non processed pre-rRNAs, DNA damage, and apoptosis that occurs in DBA. Recognition by toll like receptors (TLRs) and Mda5-like sensors induces interferons (IFNs) and inflammation. Dying cells can also activate complement system. Therefore we analyzed the status of these pathways in RP-deficient zebrafish and found upregulation of interferon, inflammatory cytokines and mediators, and complement. We also found upregulation of receptors signaling to IFNs including Mda5, Tlr3, and Tlr9. TGFb family member activin was also upregulated in RP-deficient zebrafish and in RPS19-deficient human cells, which include a lymphoid cell line from a DBA patient, and fetal liver cells and K562 cells transduced with RPS19 shRNA. Treatment of RP-deficient zebrafish with a TLR3 inhibitor decreased IFNs activation, acute phase response, and apoptosis and improved their hematopoiesis and morphology. Inhibitors of complement and activin also had beneficial effects. Our studies suggest that innate immune system contributes to the phenotype of RPS19-deficient zebrafish and human cells. PMID- 29581526 TI - HDAC genes play distinct and redundant roles in Cryptococcus neoformans virulence. AB - The human fungal pathogen Cryptococcus neoformans undergoes many phenotypic changes to promote its survival in specific ecological niches and inside the host. To explore the role of chromatin remodeling on the expression of virulence related traits, we identified and deleted seven genes encoding predicted class I/II histone deacetylases (HDACs) in the C. neoformans genome. These studies demonstrated that individual HDACs control non-identical but overlapping cellular processes associated with virulence, including thermotolerance, capsule formation, melanin synthesis, protease activity and cell wall integrity. We also determined the HDAC genes necessary for C. neoformans survival during in vitro macrophage infection and in animal models of cryptococcosis. Our results identified the HDA1 HDAC gene as a central mediator controlling several cellular processes, including mating and virulence. Finally, a global gene expression profile comparing the hda1Delta mutant versus wild-type revealed altered transcription of specific genes associated with the most prominent virulence attributes in this fungal pathogen. This study directly correlates the effects of Class I/II HDAC-mediated chromatin remodeling on the marked phenotypic plasticity and virulence potential of this microorganism. Furthermore, our results provide insights into regulatory mechanisms involved in virulence gene expression that are likely shared with other microbial pathogens.

AB - Solid state thermoelectric cooling is based on the electronic Peltier effect, which cools via an electronic heat current in the absence of an applied temperature gradient. In this work, we demonstrate that equivalently, a phonon Peltier effect may arise in the non-linear thermoelectric transport regime of a dissipative quantum dot thermoelectric setup described via Anderson-Holstein model. This effect leads to an electron induced phonon heat current in the absence of a thermal gradient. Utilizing the modification of quasi-equilibrium phonon distribution via charge induced phonon accumulation, we show that in a special case the polarity of the phonon heat current can be reversed so that setup can dump heat into the hotter reservoirs. In further exploring possibilities that can arise from this effect, we propose a novel charge-induced phonon switching mechanism that may be incited via electrostatic gating. PMID- 29581527 TI - Identification of an Arg-Leu-Arg tripeptide that contributes to the binding interface between the cytokine MIF and the chemokine receptor CXCR4. AB - MIF is a chemokine-like cytokine that plays a role in the pathogenesis of inflammatory and cardiovascular disorders. It binds to the chemokine-receptors CXCR2/CXCR4 to trigger atherogenic leukocyte migration albeit lacking canonical chemokine structures. We recently characterized an N-like-loop and the Pro-2 residue of MIF as critical molecular determinants of the CXCR4/MIF binding-site and identified allosteric agonism as a mechanism that distinguishes CXCR4-binding to MIF from that to the cognate ligand CXCL12. By using peptide spot-array technology, site-directed mutagenesis, structure-activity-relationships, and molecular docking, we identified the Arg-Leu-Arg (RLR) sequence-region 87-89 that - in three-dimensional space - 'extends' the N-like-loop to control site-1 binding to CXCR4. Contrary to wildtype MIF, mutant R87A-L88A-R89A-MIF fails to bind to the N-terminal of CXCR4 and the contribution of RLR to the MIF/CXCR4 interaction is underpinned by an ablation of MIF/CXCR4-specific signaling and reduction in CXCR4-dependent chemotactic leukocyte migration of the RLR-mutant of MIF. Alanine-scanning, functional competition by RLR-containing peptides, and molecular docking indicate that the RLR residues directly participate in contacts between MIF and CXCR4 and highlight the importance of charge-interactions at this interface. Identification of the RLR region adds important structural information to the MIF/CXCR4 binding-site that distinguishes this interface from CXCR4/CXCL12 and will help to design MIF-specific drug-targeting approaches. PMID- 29581529 TI - Enhanced protection of the renal vascular endothelium improves early outcome in kidney transplantation: Preclinical investigations in pig and mouse. AB - Ischemia reperfusion injury is one of the major complications responsible for delayed graft function in kidney transplantation. Applications to reduce reperfusion injury are essential due to the widespread use of kidneys from deceased organ donors where the risk for delayed graft function is especially prominent. We have recently shown that coating of inflamed or damaged endothelial cells with a unique heparin conjugate reduces thrombosis and leukocyte recruitment. In this study we evaluated the binding capacity of the heparin conjugate to cultured human endothelial cells, to kidneys from brain-dead porcine donors, and to murine kidneys during static cold storage. The heparin conjugate was able to stably bind cultured endothelial cells with high avidity, and to the renal vasculature of explanted kidneys from pigs and mice. Treatment of murine kidneys prior to transplantation reduced platelet deposition and leukocyte infiltration 24 hours post-transplantation, and significantly improved graft function. The present study thus shows the benefits of enhanced protection of the renal vasculature during cold storage, whereby increasing the antithrombotic and anti-adhesive properties of the vascular endothelium yields improved renal function early after transplantation. PMID- 29581530 TI - Genomic expansion of magnetotactic bacteria reveals an early common origin of magnetotaxis with lineage-specific evolution. AB - The origin and evolution of magnetoreception, which in diverse prokaryotes and protozoa is known as magnetotaxis and enables these microorganisms to detect Earth's magnetic field for orientation and navigation, is not well understood in evolutionary biology. The only known prokaryotes capable of sensing the geomagnetic field are magnetotactic bacteria (MTB), motile microorganisms that biomineralize intracellular, membrane-bounded magnetic single-domain crystals of either magnetite (Fe3O4) or greigite (Fe3S4) called magnetosomes. Magnetosomes are responsible for magnetotaxis in MTB. Here we report the first large-scale metagenomic survey of MTB from both northern and southern hemispheres combined with 28 genomes from uncultivated MTB. These genomes expand greatly the coverage of MTB in the Proteobacteria, Nitrospirae, and Omnitrophica phyla, and provide the first genomic evidence of MTB belonging to the Zetaproteobacteria and "Candidatus Lambdaproteobacteria" classes. The gene content and organization of magnetosome gene clusters, which are physically grouped genes that encode proteins for magnetosome biosynthesis and organization, are more conserved within phylogenetically similar groups than between different taxonomic lineages. Moreover, the phylogenies of core magnetosome proteins form monophyletic clades. Together, these results suggest a common ancient origin of iron-based (Fe3O4 and Fe3S4) magnetotaxis in the domain Bacteria that underwent lineage-specific evolution, shedding new light on the origin and evolution of biomineralization and magnetotaxis, and expanding significantly the phylogenomic representation of MTB. PMID- 29581531 TI - Bi-directional coupling in strain-mediated multiferroic heterostructures with magnetic domains and domain wall motion. AB - Strain-coupled multiferroic heterostructures provide a path to energy-efficient, voltage-controlled magnetic nanoscale devices, a region where current-based methods of magnetic control suffer from Ohmic dissipation. Growing interest in highly magnetoelastic materials, such as Terfenol-D, prompts a more accurate understanding of their magnetization behavior. To address this need, we simulate the strain-induced magnetization change with two modeling methods: the commonly used unidirectional model and the recently developed bidirectional model. Unidirectional models account for magnetoelastic effects only, while bidirectional models account for both magnetoelastic and magnetostrictive effects. We found unidirectional models are on par with bidirectional models when describing the magnetic behavior in weakly magnetoelastic materials (e.g., Nickel), but the two models deviate when highly magnetoelastic materials (e.g., Terfenol-D) are introduced. These results suggest that magnetostrictive feedback is critical for modeling highly magnetoelastic materials, as opposed to weaker magnetoelastic materials, where we observe only minor differences between the two methods' outputs. To our best knowledge, this work represents the first comparison of unidirectional and bidirectional modeling in composite multiferroic systems, demonstrating that back-coupling of magnetization to strain can inhibit formation and rotation of magnetic states, highlighting the need to revisit the assumption that unidirectional modeling always captures the necessary physics in strain-mediated multiferroics. PMID- 29581532 TI - C-type lectins in immunity and homeostasis. AB - The C-type lectins are a superfamily of proteins that recognize a broad repertoire of ligands and that regulate a diverse range of physiological functions. Most research attention has focused on the ability of C-type lectins to function in innate and adaptive antimicrobial immune responses, but these proteins are increasingly being recognized to have a major role in autoimmune diseases and to contribute to many other aspects of multicellular existence. Defects in these molecules lead to developmental and physiological abnormalities, as well as altered susceptibility to infectious and non-infectious diseases. In this Review, we present an overview of the roles of C-type lectins in immunity and homeostasis, with an emphasis on the most exciting recent discoveries. PMID- 29581533 TI - Highly efficient Fenton and enzyme-mimetic activities of NH2-MIL-88B(Fe) metal organic framework for methylene blue degradation. AB - Here, we show that NH2-MIL-88B(Fe) can be used as a peroxidase-like catalyst for Fenton-like degradation of methylene blue (MB) in water. The iron-based NH2-MIL 88B(Fe) metal organic framework (MOF) was synthesized by a facile and rapid microwave heating method. It was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, powder X-ray diffraction, and the Brunauer-Emmett-Teller method. The NH2-MIL-88B(Fe) MOF possesses intrinsic oxidase-like and peroxidase-like activities. The reaction parameters that affect MB degradation were investigated, including the solution pH, NH2-MIL-88B(Fe) MOF and H2O2 concentrations, and temperature. The results show that the NH2-MIL 88B(Fe) MOF exhibits a wide working pH range (pH 3.0-11.0), temperature tolerance, and good recyclability for MB removal. Under the optimal conditions, complete removal of MB was achieved within 45 min. In addition, removal of MB was above 80% after five cycles, showing the good recyclability of NH2-MIL-88B(Fe). The NH2-MIL-88B(Fe) MOF has the features of easy preparation, high efficiency, and good recyclability for MB removal in a wide pH range. Electron spin resonance and fluorescence probe results suggest the involvement of hydroxyl radicals in MB degradation. These findings provide new insight into the application of high efficient MOF-based Fenton-like catalysts for water purification. PMID- 29581534 TI - MicroRNA-1 suppresses proliferation, migration and invasion by targeting Notch2 in esophageal squamous cell carcinoma. AB - MicroRNAs play an important role in the migration and invasion of tumors, and lower expression of microRNA-1 (miR-1) has been proven in a variety of malignant tumors, including esophageal squamous cell carcinoma (ESCC). In this study, we found that miR-1 expression levels in tumor tissues and preoperative serum from esophageal carcinoma patients were lower than those in non-tumorous tissues and healthy volunteers. miR-1 expression in tissues and plasma was closely related to invasion, lymph node metastasis and TNM staging. Additionally, miR-1 expression levels in tissues and plasma were positively correlated. miR-1 inhibited cell proliferation, migration and invasion. Overexpression of miR-1 in ESCC cells reduced Notch2 protein but not mRNA levels, whereas suppression of miR-1 led to an increase in Notch2 protein but not mRNA levels. A dual-luciferase experiment validated that Notch2 was a direct target of miR-1. Introducing Notch2 mRNA into cells over-expressing miR-1 partially abrogated the effects of miR-1 on migration and invasion. Further studies verified that miR-1 regulates EMT signalling pathways directly through Notch2. Therefore, these results confirm that, as a tumor suppressor gene, miR-1 may be a potential tumor marker for the early diagnosis of ESCC and a new drug target. PMID- 29581535 TI - Mitochondrial fragmentation affects neither the sensitivity to TNFalpha-induced apoptosis of Brucella-infected cells nor the intracellular replication of the bacteria. AB - Mitochondria are complex organelles that participate in many cellular functions, ranging from ATP production to immune responses against viruses and bacteria. This integration of a plethora of functions within a single organelle makes mitochondria a very attractive target to manipulate for intracellular pathogens. We characterised the crosstalk that exists between Brucella abortus, the causative agent of brucellosis, and the mitochondria of infected cells. Brucella replicates in a compartment derived from the endoplasmic reticulum (ER) and modulates ER functionality by activating the unfolded protein response. However, the impact of Brucella on the mitochondrial population of infected cells still requires a systematic study. We observed physical contacts between Brucella containing vacuoles and mitochondria. We also found that B. abortus replication is independent of mitochondrial oxidative phosphorylation and that mitochondrial reactive oxygen species do not participate to the control of B. abortus infection in vitro. We demonstrated that B. abortus and B. melitensis induce a drastic mitochondrial fragmentation at 48 hours post-infection in different cell types, including myeloid and non-myeloid cells. This fragmentation is DRP1-independent and might be caused by a deficit of mitochondrial fusion. However, mitochondrial fragmentation does not change neither Brucella replication efficiency, nor the susceptibility of infected cells to TNFalpha-induced apoptosis. PMID- 29581536 TI - Neural activation to monetary reward is associated with amphetamine reward sensitivity. AB - One known risk factor for drug use and abuse is sensitivity to rewarding effects of drugs. It is not known whether this risk factor extends to sensitivity to non drug rewards. In this study with healthy young adults, we examined the association between sensitivity to the subjective rewarding effects of amphetamine and a neural indicator of anticipation of monetary reward. We hypothesized that greater euphorigenic response to amphetamine would be associated with greater neural activation to anticipation of monetary reward (Win > Loss). Healthy participants (N = 61) completed four laboratory sessions in which they received d-amphetamine (20 mg) and placebo in alternating order, providing self-report measures of euphoria and stimulation at regular intervals. At a separate visit 1-3 weeks later, participants completed the guessing reward task (GRT) during fMRI in a drug-free state. Participants reporting greater euphoria after amphetamine also exhibited greater neural activation during monetary reward anticipation in mesolimbic reward regions, including the bilateral caudate and putamen. This is the first study to show a relationship between neural correlates of monetary reward and sensitivity to the subjective rewarding effects of amphetamine in humans. These findings support growing evidence that sensitivity to reward in general is a risk factor for drug use and abuse, and suggest that sensitivity of drug-induced euphoria may reflect a general sensitivity to rewards. This may be an index of vulnerability for drug use or abuse. PMID- 29581539 TI - Slab narrowing in the Central Mediterranean: the Calabro-Ionian subduction zone as imaged by high resolution seismic tomography. AB - A detailed 3D image of the Calabro-Ionian subduction system in the central Mediterranean was obtained by means of a seismic tomography, exploiting a large dataset of local earthquakes and computing algorithms able to build a dense grid of measure nodes. Results show that the slab is continuous below the southern sector of the Calabro-Peloritan Arc, but the deformation processes developing at its edges are leading to its progressive narrowing, influencing tectonics and magmatism at the surface, and with possible stress concentration in the tip zones. In the southwest, the deformation occurring at a free slab edge lead to propagation of a vertical lithospheric tear in the overriding plate, which extends along a NW-SE fault system (Aeolian-Tindari-Letojanni) up to about 30 km into the Ionian Sea; further southeast, the lithosphere appears only flexed and not broken yet. In the northeast, the slab seems to break progressively, parallel to the trench. Finally, northwest of Mt. Etna, the tomography highlights low VP that can be related to an upwelling of deep mantle material likely flowing laterally through a window opened by the complete slab detachment. PMID- 29581538 TI - Brain lactate and pH in schizophrenia and bipolar disorder: a systematic review of findings from magnetic resonance studies. AB - Converging evidence from molecular to neuroimaging studies suggests brain energy metabolism abnormalities in both schizophrenia and bipolar disorder. One emerging hypothesis is: decreased oxidative phosphorylation leading to accumulation of lactic acid from glycolysis and subsequent acidification of tissue. In this regard, integrating lactate and pH data from magnetic resonance spectroscopy (MRS) studies in both diseases may help us understand underlying neurobiological mechanisms. In order to achieve this goal, we performed a systematic search of case-control studies examining brain lactate or pH among schizophrenia and/or bipolar patients by using MRS. Medline/Pubmed and EBSCO databases were searched separately for both diseases and outcomes. Our search yielded 33 studies in total composed of 7 lactate and 26 pH studies. In bipolar disorder, 5 out of 6 studies have found elevated lactate levels especially in the cingulate cortex and 4 out of 13 studies reported reduced pH in the frontal lobe. In contrast, in schizophrenia a single study has examined lactate and reported elevation, while only 2 out of 13 studies examining pH have reported reduction in this measure. There were no consistent patterns for the relationship between lactate or pH levels and medication use, disease type, mood state, and other clinical variables. We highlight the need for future studies combining 1H-MRS and 31P-MRS approaches, using longitudinal designs to examine lactate and pH in disease progression across both schizophrenia and bipolar disorders. PMID- 29581537 TI - M1-positive allosteric modulators lacking agonist activity provide the optimal profile for enhancing cognition. AB - Highly selective positive allosteric modulators (PAMs) of the M1 subtype of muscarinic acetylcholine receptor have emerged as an exciting new approach for improving cognitive function in patients suffering from Alzheimer's disease and schizophrenia. However, excessive activation of M1 is known to induce seizure activity and have actions in the prefrontal cortex (PFC) that could impair cognitive function. We now report a series of pharmacological, electrophysiological, and behavioral studies in which we find that recently reported M1 PAMs, PF-06764427 and MK-7622, have robust agonist activity in cell lines and agonist effects in the mouse PFC, and have the potential to overactivate the M1 receptor and disrupt PFC function. In contrast, structurally distinct M1 PAMs (VU0453595 and VU0550164) are devoid of agonist activity in cell lines and maintain activity dependence of M1 activation in the PFC. Consistent with the previously reported effect of PF-06764427, the ago-PAM MK-7622 induces severe behavioral convulsions in mice. In contrast, VU0453595 does not induce behavioral convulsions at doses well above those required for maximal efficacy in enhancing cognitive function. Furthermore, in contrast to the robust efficacy of VU0453595, the ago-PAM MK-7622 failed to improve novel object recognition, a rodent assay of cognitive function. These findings suggest that in vivo cognition enhancing efficacy of M1 PAMs can be observed with PAMs lacking intrinsic agonist activity and that intrinsic agonist activity of M1 PAMs may contribute to adverse effects and reduced efficacy in improving cognitive function. PMID- 29581540 TI - Lower serum calcium is independently associated with CKD progression. AB - Disturbances in calcium metabolism are common in individuals with chronic kidney disease (CKD), but whether they are associated with subsequent kidney function decline is less clear. In a CKD 3-5 cohort of 15,755 adult citizens of Stockholm with creatinine tests taken during 2006-2011 and concurrent calcium testing at cohort entry, we investigated the association between baseline serum calcium and the subsequent change in estimated glomerular filtration rate (eGFR, by CKD-EPI) decline using linear mixed models. Mean (SD) baseline corrected serum calcium was 9.6 (0.5) mg/dL. Mean (95%-confidence interval [CI]) eGFR decline was -0.82 ( 0.90; -0.74) mL/min/1.73 m2/year. In advanced CKD stages, higher baseline serum calcium was associated with less rapid kidney function decline. The adjusted change (95%-CI) in eGFR decline associated with each mg/dL increase in baseline serum calcium was -0.10 (-0.28; 0.26), 0.39 (0.07; 0.71), 0.34 (-0.02; 0.70) and 0.68 (0.36; 1.00) mL/min/1.73 m2/year for individuals in CKD stage 3a, 3b, 4, and 5, respectively. In a subgroup of patients using vitamin D supplements, the association between baseline serum calcium and CKD progression was eliminated, especially in CKD stage 3b and 4. To conclude, in individuals with CKD stage 3b to 5, lower baseline corrected serum calcium, rather than higher baseline serum calcium, associated with a more rapid CKD progression. Lower serum corrected calcium seems to be indicative for vitamin D deficiency. PMID- 29581542 TI - Detailed genomic characterization identifies high heterogeneity and histotype specific genomic profiles in adrenocortical carcinomas. AB - Molecular characterization of adrenocortical carcinoma has been recently established, but the correlation between molecular profiles and clinical and pathological characteristics is still poorly defined with no data available about genetic heterogeneity along disease progression. In this scenario, a detailed molecular profile was correlated with clinical and pathological characteristics in adrenocortical carcinoma patients to identify potentially novel biomarkers. Targeted next-generation sequencing and copy number variation analyses for 18 most frequently altered genes in adrenocortical carcinoma were assessed on 62 adult cases (including 10 with matched primary and metastatic/recurrence samples) and results correlated with major clinical and pathological characteristics of tumors. A total of 433 somatic deleterious genetic alterations (328 gene mutations and 105 copy number variations) were identified in 57/62 cases, five resulted wild type for all genes tested. TERT, CDK4, ZNRF3,and RB1 were altered in more than 30% of cases. Among histological variants genotypes were significantly different. Lowest mutation burden was found in the oncocytic type (p = 0.006), whereas the highest with a prevalence of RB1 (p = 0.001) and CDK4 (p = 0.002) was found in the conventional and myxoid ones, respectively. None of the 10 cases with matched samples showed a stable genotype along tumor progression, although allelic frequencies or percentages of altered nuclei at fluorescence in situ hybridization were in most cases similar among different tumor samples for genes that were stable along tumor progression. Among individual genes, an altered p53/Rb1 pathway was the strongest adverse molecular signature, being associated with high Ki-67 index, high tumor stage, aggressive disease status, and shorter disease-free survival. The genomic signature in adrenocortical carcinoma is changing along tumor progression and is associated with specific clinical and pathological features, including histological variant and prognosis. PMID- 29581541 TI - Structure-based discovery of mPGES-1 inhibitors suitable for preclinical testing in wild-type mice as a new generation of anti-inflammatory drugs. AB - Human mPGES-1 is recognized as a promising target for next generation of anti inflammatory drugs without the side effects of currently available anti inflammatory drugs, and various inhibitors have been reported in the literature. However, none of the reported potent inhibitors of human mPGES-1 has shown to be also a potent inhibitor of mouse or rat mPGES-1, which prevents using the well established mouse/rat models of inflammation-related diseases for preclinical studies. Hence, despite of extensive efforts to design and discover various human mPGES-1 inhibitors, the promise of mPGES-1 as a target for the next generation of anti-inflammatory drugs has never been demonstrated in any wild-type mouse/rat model using an mPGES-1 inhibitor. Here we report discovery of a novel type of selective mPGES-1 inhibitors potent for both human and mouse mPGES-1 enzymes through structure-based rational design. Based on in vivo studies using wild-type mice, the lead compound is indeed non-toxic, orally bioavailable, and more potent in decreasing the PGE2 (an inflammatory marker) levels compared to the currently available drug celecoxib. This is the first demonstration in wild-type mice that mPGES-1 is truly a promising target for the next generation of anti-inflammatory drugs. PMID- 29581543 TI - Programmed cell death ligand-1 expression in tumor and immune cells is associated with better patient outcome and decreased tumor-infiltrating lymphocytes in uveal melanoma. AB - Programmed cell death-1/ligand (PD-1/PD-L1) interaction negatively regulates T cell activity. PD-L1 expression in tumor cells, antigen-presenting cells, and lymphocytes of the tumor microenvironment is associated with response to treatment with PD-1/PD-L1 inhibitors, but there is still debate on the cutoff value that correlates with responders. In uveal melanoma (UM), 40% of patients will develop liver metastases and, amongst them, 90% will succumb to their disease. The aim of this study was to analyze PD-L1 expression as a prognostic marker and as a possible therapeutic target for UM. Sixty-seven enucleated eyes from UM patients with relevant clinical information were analyzed. Univariate and multivariate analysis were used to evaluate association of PD-L1 with survival. PD-L1 expression was positive relatively to tumor cells, immune cells, and the tumor and tumor-infiltrating immune cell group scoring in 46, 34 and 55% of the cases, respectively. On univariate analysis, tumor cells and the tumor and tumor infiltrating immune cell group PD-L1 expression was associated with a longer metastasis-free survival (P = 0.04 and P = 0.007). However, on multivariate analysis, only the tumor and tumor-infiltrating immune cell group positivity was associated with longer metastasis-free survival (P = 0.01). Furthermore, tumor cells and the tumor and tumor-infiltrating immune cell group PD-L1 expression was associated with decreased tumor-infiltrating lymphocytes (P = 0.02). PD-L1, when expressed in uveal melanoma, is associated with better patient outcome and decreased tumor-infiltrating lymphocytes. These results support the consideration of anti-PD-1/PD-L1 therapy in uveal melanoma. To determine the best cutoff value, further studies from patients enrolled in clinical trials treated with PD-1/PD-L1 inhibitors are necessary. PMID- 29581544 TI - Double-hit or dual expression of MYC and BCL2 in primary cutaneous large B-cell lymphomas. AB - In nodal diffuse large B-cell lymphoma, the search for double-hit with MYC and BCL2 and/or BCL6 rearrangements or for dual expression of BCL2 and MYC defines subgroups of patients with altered prognosis that has not been evaluated in primary cutaneous large B-cell lymphoma. Our objectives were to assess the double hit and dual expressor status in a cohort of 44 patients with primary cutaneous large B-cell lymphoma according to the histological subtype and to evaluate their prognosis relevance. The 44 cases defined by the presence of more than 80% of large B-cells in the dermis corresponded to 21 primary cutaneous follicle centre lymphoma with large cell morphology and 23 primary cutaneous diffuse large B-cell lymphoma, leg type. Thirty-one cases (70%) expressed BCL2 and 29 (66%) expressed MYC. Dual expressor profile was observed in 25 cases (57%) of either subtypes (n = 6 or n = 19, respectively). Only one primary cutaneous follicle centre lymphoma, large-cell case had a double-hit status (2%). Specific survival was significantly worse in primary cutaneous diffuse large B-cell lymphoma, leg type than in primary cutaneous follicle centre lymphoma, large cell (p = 0.021) and for the dual expressor primary cutaneous large B-cell lymphoma group (p = 0.030). Both overall survival and specific survival were worse for patients belonging to the dual expressor primary cutaneous diffuse large B-cell lymphoma, leg type subgroup (p = 0.001 and p = 0.046, respectively). Expression of either MYC and/or BCL2 negatively impacted overall survival (p = 0.017 and p = 0.018 respectively). As the differential diagnosis between primary cutaneous follicle centre lymphoma, large cell and primary cutaneous diffuse large B-cell lymphoma, leg type has a major impact on prognosis, dual-expression of BCL2 and MYC may represent a new diagnostic criterion for primary cutaneous diffuse large B-cell lymphoma, leg type subtype and further identifies patients with impaired survival. Finally, the double-hit assessment does not appear clinically relevant in primary cutaneous large B-cell lymphoma. PMID- 29581545 TI - Microglia remodel synapses by presynaptic trogocytosis and spine head filopodia induction. AB - Microglia are highly motile glial cells that are proposed to mediate synaptic pruning during neuronal circuit formation. Disruption of signaling between microglia and neurons leads to an excess of immature synaptic connections, thought to be the result of impaired phagocytosis of synapses by microglia. However, until now the direct phagocytosis of synapses by microglia has not been reported and fundamental questions remain about the precise synaptic structures and phagocytic mechanisms involved. Here we used light sheet fluorescence microscopy to follow microglia-synapse interactions in developing organotypic hippocampal cultures, complemented by a 3D ultrastructural characterization using correlative light and electron microscopy (CLEM). Our findings define a set of dynamic microglia-synapse interactions, including the selective partial phagocytosis, or trogocytosis (trogo-: nibble), of presynaptic structures and the induction of postsynaptic spine head filopodia by microglia. These findings allow us to propose a mechanism for the facilitatory role of microglia in synaptic circuit remodeling and maturation. PMID- 29581546 TI - Depth of organ response in AL amyloidosis is associated with improved survival: grading the organ response criteria. AB - Organ recovery following anti-plasma cell therapy is associated with improved outcome in patients with AL amyloidosis. Current organ response criteria do not consider the depth of response. Newly diagnosed AL amyloidosis patients who had involvement of at least one evaluable organ and documentation of organ response were included. Cardiac response was seen in 182 patients. Time to cardiac response was 9.4 months. Renal response was seen in 278 patients, at a median time to response of 6 months. Hepatic response was seen in 70 patients, with a median time to response of 6.1 months. In all organs, the deeper the organ response achieved, the longer the survival. This led to four organ response criteria: complete organ response (nadir NT-proBNP <=400 pg/mL; nadir proteinuria <=200 mg per 24 h; nadir alkaline phosphatase <=*2 lower limit of normal); very good partial organ response (>60% reduction in parameter not meeting complete organ response definition); partial organ response (31-60% reduction in parameter); and non-responder (<=30% reduction in organ response parameter). Cardiac and renal progression were associated with baseline organ impairment and inversely associated with the depth of organ response. Grading the depth of organ response provides additional valuable prognostic information for newly diagnosed AL amyloidosis patients. PMID- 29581548 TI - Charge transport in the inverted Marcus region. PMID- 29581549 TI - Transition from direct to inverted charge transport Marcus regions in molecular junctions via molecular orbital gating. AB - Solid-state molecular tunnel junctions are often assumed to operate in the Landauer regime, which describes essentially activationless coherent tunnelling processes. In solution, on the other hand, charge transfer is described by Marcus theory, which accounts for thermally activated processes. In practice, however, thermally activated transport phenomena are frequently observed also in solid state molecular junctions but remain poorly understood. Here, we show experimentally the transition from the Marcus to the inverted Marcus region in a solid-state molecular tunnel junction by means of intra-molecular orbital gating that can be tuned via the chemical structure of the molecule and applied bias. In the inverted Marcus region, charge transport is incoherent, yet virtually independent of temperature. Our experimental results fit well to a theoretical model that combines Landauer and Marcus theories and may have implications for the interpretation of temperature-dependent charge transport measurements in molecular junctions. PMID- 29581547 TI - Protein targeting chimeric molecules specific for bromodomain and extra-terminal motif family proteins are active against pre-clinical models of multiple myeloma. AB - Bromodomain and extraterminal (BET) domain containing protein (BRD)-4 modulates the expression of oncogenes such as c-myc, and is a promising therapeutic target in diverse cancer types. We performed pre-clinical studies in myeloma models with bi-functional protein-targeting chimeric molecules (PROTACs) which target BRD4 and other BET family members for ubiquitination and proteasomal degradation. PROTACs potently reduced the viability of myeloma cell lines in a time-dependent and concentration-dependent manner associated with G0/G1 arrest, reduced levels of CDKs 4 and 6, increased p21 levels, and induction of apoptosis. These agents specifically decreased cellular levels of downstream BRD4 targets, including c MYC and N-MYC, and a Cereblon-targeting PROTAC showed downstream effects similar to those of an immunomodulatory agent. Notably, PROTACs overcame bortezomib, dexamethasone, lenalidomide, and pomalidomide resistance, and their activity was maintained in otherwise isogenic myeloma cells with wild-type or deleted TP53. Combination studies showed synergistic interactions with dexamethasone, BH3 mimetics, and Akt pathway inhibitors. BET-specific PROTACs induced a rapid loss of viability of primary cells from myeloma patients, and delayed growth of MM1.S based xenografts. Our data demonstrate that BET degraders have promising activity against pre-clinical models of multiple myeloma, and support their translation to the clinic for patients with relapsed and/or refractory disease. PMID- 29581550 TI - When radionuclides meet nanoparticles. PMID- 29581551 TI - Nanoparticles as multimodal photon transducers of ionizing radiation. AB - In biomedical imaging, nanoparticles combined with radionuclides that generate Cerenkov luminescence are used in diagnostic imaging, photon-induced therapies and as activatable probes. In these applications, the nanoparticle is often viewed as a carrier inert to ionizing radiation from the radionuclide. However, certain phenomena such as enhanced nanoparticle luminescence and generation of reactive oxygen species cannot be completely explained by Cerenkov luminescence interactions with nanoparticles. Herein, we report methods to examine the mechanisms of nanoparticle excitation by radionuclides, including interactions with Cerenkov luminescence, beta particles and gamma radiation. We demonstrate that beta-scintillation contributes appreciably to excitation and reactivity in certain nanoparticle systems, and that excitation by radionuclides of nanoparticles composed of large atomic number atoms generates X-rays, enabling multiplexed imaging through single photon emission computed tomography. These findings demonstrate practical optical imaging and therapy using radionuclides with emission energies below the Cerenkov threshold, thereby expanding the list of applicable radionuclides. PMID- 29581552 TI - Ambipolar Landau levels and strong band-selective carrier interactions in monolayer WSe2. AB - Monolayers (MLs) of transition-metal dichalcogenides (TMDs) exhibit unusual electrical behaviour under magnetic fields due to their intrinsic spin-orbit coupling and lack of inversion symmetry1-15. Although recent experiments have also identified the critical role of carrier interactions within these materials11,15, a complete mapping of the ambipolar Landau level (LL) sequence has remained elusive. Here we use single-electron transistors (SETs)16,17 to perform LL spectroscopy in ML WSe2, and provide a comprehensive picture of the electronic structure of a ML TMD for both electrons and holes. We find that the LLs differ notably between the two bands, and follow a unique sequence in the valence band (VB) that is dominated by strong Zeeman effects. The Zeeman splitting in the VB is several times higher than the cyclotron energy, far exceeding the predictions of a single-particle model and, moreover, tunes significantly with doping 15 . This implies exceptionally strong many-body interactions, and suggests that ML WSe2 can serve as a host for new correlated electron phenomena. PMID- 29581553 TI - Body mass index, abdominal fatness, and hypertension incidence: a dose-response meta-analysis of prospective studies. AB - Despite the established relationship of obesity to hypertension, the question as to whether there is a linear association between these two morbidities is unanswered. To quantitatively evaluate the relationship between obesity and hypertension, we carried out a dose-response meta-analysis of studies that looked at the relationship of different adiposity measures to hypertension. We searched PubMed, Embase, and Web of Science databases for articles published before 27 June 2017. A random-effects model was used to pool relative risks and 95% confidence intervals. Restricted cubic spline analysis was used to model the relationship. A total of 59 studies were included. Fifty-seven cohort studies with 125,071 incident cases among 830,685 participants were included in the analysis of body mass index and hypertension with the summary relative risk for per 5-unit increment in body mass index of 1.50 (95% confidence interval: 1.40 1.59). We found that the risk of hypertension in the body mass index analysis was greater in populations where the baseline body mass index was <25 kg/m2. The summary relative risk for a 10-cm increase in waist circumference was 1.25 (95% confidence interval: 1.19-1.32) and per 0.1-unit increase in waist-to-hip ratio was 1.27 (95% confidence interval: 1.18-1.37). This meta-analysis suggests that in normal range of obesity indexes, as lean as possible may be the best suggestion to prevent hypertension incidence. PMID- 29581554 TI - Heart rate reduction decreases central blood pressure in sick sinus syndrome patients with a permanent cardiac pacemaker. AB - Increased resting heart rate (HR) contributes to higher cardiovascular mortality and morbidity in the healthy as well as in people with cardiovascular diseases, possibly due to elevated blood pressure (BP) among other mechanisms. Data on the relationship between HR and central (aortic) BP remains controversial, however, and concerning beta-blockers, it has been proposed that pharmacological HR lowering is associated with augmentation of central BP. We aimed to study the role of pharmacologically unaffected HR on central BP indices in sick sinus syndrome patients with a permanent cardiac pacemaker in the HR range from 40 to 90 bpm. We included 27 subjects (mean age 65.8 +/- 9.5 years, 12 men) with a dual chamber pacemaker implanted due to sick sinus syndrome. We determined central hemodynamic indices noninvasively during an atrial pacing mode at low (40 bpm), middle (60 bpm), and high (90 bpm) HR levels with an oscillometric cuff-based device (Sphygmocor XCEL). There was no difference in central systolic BP at the middle versus the high HR level (mean 121.2 +/- 13.0 and 121.2 +/- 12.1 mmHg, respectively, P = 0.9), but at the low HR level, it was significantly lower than at the middle HR level (mean 117.2 +/- 13.1 and 121.2 +/- 13.0 mmHg, P < 0.01). Our acute study provides evidence to suggest that at a HR of <60 bpm, sick sinus syndrome patients may have a lower central BP than at a higher HR, despite the proposed augmenting effects of low HR on central BP. PMID- 29581555 TI - Comparison of various anthropometric indices for the identification of a predictor of incident hypertension: the ARIRANG study. AB - We compared the predictive capability of weight, waist circumference (WC), waist to-height ratio (WHtR), waist-to-hip ratio (WHR), body mass index (BMI), body roundness index (BRI), and a body shape index (ABSI) to identify incident hypertension, and to determine whether any of these indices may be used as a better single predictor of incident hypertension. A total of 1718 participants aged 39-72 years were collected in a longitudinal study. Logistic regression models were used to evaluate various anthropometric indices as significant predictors of hypertension. During 2.8 years of follow-up, 185 new cases of hypertension (10.8%) were reported. The BRI and ABSI were significantly higher in the participants who had developed hypertension than in those who had not (4.15 +/- 1.01 vs. 3.57 +/- 1.03, 0.80 +/- 0.04 vs. 0.78 +/- 0.05; respectively, p < 0.001). After adjusting for confounding variables, logistic regression analysis indicated that participants within the highest quartile of WC and WHtR were 4.79 and 4.51 times more likely to have hypertension than those within the lowest quartile (OR 4.79, 95% CI 2.49-9.20 vs. OR 4.51, 95% CI 2.41-8.43, respectively, p < 0.0001); in contrast, no such correlation was found for BMI, WHR, BRI, and ABSI. WC (AUC: 0.672) showed a more powerful predictive ability for hypertension (p < 0.0001) than BMI (AUC: 0.623), and an equal predictive power for hypertension as WHtR (AUC: 0.662) and BRI (AUC: 0.662) in the general population. We concluded that WC and/or WHtR but not BMI, showed superior prediction capability compared to WHR, BRI, and ABSI, for determining the incidence of hypertension in a community-based prospective study. PMID- 29581556 TI - Salt sensitivity of blood pressure at age 8 years in children born preterm. AB - Preterm birth and low birth weight have been associated with an increased risk of hypertension; postnatal growth and dietary salt intake may contribute to these associations. In adults, the change of blood pressure (BP) in response to modifications in salt intake, i.e., salt sensitivity of BP, has been independently associated with cardiovascular disease. Little is known about salt sensitivity in children. We hypothesize that it may partly explain the association between preterm birth and higher BP in later life. We assessed salt sensitivity of BP at age 8 years in 63 preterm-born children, and explored its association with postnatal growth, sodium intake, and body composition from infancy onwards. BP was measured at baseline and after a 7-day high-salt diet. The difference in mean arterial pressure (MAP) was calculated; salt sensitivity was defined as an increase in MAP of >=5%. Ten children (16%) showed salt sensitivity of BP, which was associated with neonatal growth restriction as well as with lower fat mass and BMI from infancy onwards. At age 8 years, children classified as salt sensitive had a lower weight-for-age SD-score (-1.5 +/- 1.3 vs. -0.6 +/- 1.1) and BMI (13.8 +/- 1.7 vs. 15.5 +/- 1.8 kg/m2) compared to their salt resistant counterparts. Sodium intake was not associated with (salt sensitivity of) BP. Salt sensitivity of BP was demonstrated in preterm-born children at age 8 years and may contribute to the development of cardiovascular disease at later age. Long-term follow-up studies are necessary to assess reproducibility of our findings and to explore clustering with other cardiovascular risk factors. PMID- 29581557 TI - Less primary fistula failure in hypertensive patients. AB - End stage renal disease (ESRD) patients suffer from advanced renal diseases and actually nonfunctioning kidneys, and need kidney transplantation or dialysis. Hemodialysis (HD) is the most used method and requires a vascular access (VA). Arteriovenous fistula (AVF) is the first choice of VA over the world for having least morbidity and mortality. Despite the wide-spread use of AVFs, the rate of AVF failures are notable. Detecting the factors that cause AVF failure can reduce repeating VA surgeries and hospitalization of ESRD patients. Present research studies 480 Iranian HD patients who underwent AVF surgery from 2010 to 2017 and aged 18-90 years old, using data mining techniques. (i) The AVF failure rate was equal to 8.96%, such that AVF failure has occurred in 3.54% and 5.52% of HD patient with and without hypertension, respectively. (ii) The rate of non-failure AVF in hypertensive patients is 61.46%, whereas the same rate for patients with negative history of hypertension reaches to 29.58%. (iii) Hypertension has a significant inverse association with AVF failure (Spearman's rho = -0.160, P value <= 0.005). (iv) The decision tree (with accuracy rate = 92.24%) shows less AVF failure in hypertsensive patients (5.53%) comparing with non-hypertensive patients (15.09%). (v) The AVFs with greater failure rates and non-hypertensive HD patients were clustered together. "Significantly lower risk of AVF failure was associated with presence of a positive history of hypertension; in other words, positive history of hypertension has an adverse effect on AVF failure and Hypertensive HD patients have more maturated AVF." PMID- 29581558 TI - Identification of Urinary Activin A as a Novel Biomarker Reflecting the Severity of Acute Kidney Injury. AB - Acute kidney injury (AKI) is a common but complex condition that is associated with increased morbidity and mortality. In the present study, we examined whether urinary activin A, a member of the TGF-beta superfamily, is present in mice with ischemia-reperfusion injury and in humans with AKI, as well as its potential as a biomarker for AKI. Expression of activin A was markedly increased in ischemic mouse kidneys. In situ hybridization demonstrated that activin mRNA was expressed in tubular cells of ischemic kidneys but not of normal kidneys. Immunoreactive activin A, which was absent in normal kidneys, was detected in the cytoplasm of proximal tubular cells in ischemic kidneys. Activin A was undetectable in the urine of normal mice. In contrast, activin A was significantly increased in the urine of ischemic mice at 3 h after reperfusion. Urinary activin A levels increased according to the period of ischemia. In humans, urinary activin A was almost undetectable in healthy volunteers and in patients with pre-renal AKI, but was significantly increased in patients with renal AKI. There was no significant correlation between urinary activin A and serum activin A. Collectively, urinary activin A might be a useful biomarker reflecting the severity of AKI. PMID- 29581559 TI - Improvement of physical properties of calcium phosphate cement by elastin-like polypeptide supplementation. AB - Calcium phosphate cements (CPCs) are synthetic bioactive cements widely used as hard tissue substitutes. Critical limitations of use include their poor mechanical properties and poor anti-washout behaviour. To address those limitations, we combined CPC with genetically engineered elastin-like polypeptides (ELPs). We investigated the effect of the ELPs on the physical properties and biocompatibility of CPC by testing ELP/CPC composites with various liquid/powder ratios. Our results show that the addition of ELPs improved the mechanical properties of the CPC, including the microhardness, compressive strength, and washout resistance. The biocompatibility of ELP/CPC composites was also comparable to that of the CPC alone. However, supplementing CPC with ELPs functionalized with octaglutamate as a hydroxyapatite binding peptide increased the setting time of the cement. With further design and modification of our biomolecules and composites, our research will lead to products with diverse applications in biology and medicine. PMID- 29581560 TI - Surface enhanced Raman spectroscopy of Chlamydia trachomatis and Neisseria gonorrhoeae for diagnostics, and extra-cellular metabolomics and biochemical monitoring. AB - SERS spectra excited at 785 nm of the bacteria Chlamydia trahomatis (elementary bodies, EB) and Neisseria gonorrheoae, the causative pathogens for the two most common sexually transmitted diseases (STD), chlamydia and gonorrhea, respectively, are reported. Although both are Gram-negative bacteria, the SERS signatures of C. trachomatis and N. gonorrheoae are completely different. N. gonorrheoae SERS spectra are due to the starvation induced nucleotide metabolites adenine and guanine, and the surface associated co-enzyme nicotinamide adenine dinucleotide and are very similar on Au and Ag although the spectrum appears more rapidly on Ag. The C. trachomatis SERS spectrum is dominated by the vibrational features of cell surface proteins. While features attributable to specific residues and the amide backbone characterize the C. trachomatis spectrum on Ag, the corresponding SERS spectrum on Au substrates displays vibrational characteristics of aggregated proteins. The prospects for the development of a SERS based platform for rapid (5) cohort (n = 35) lost significantly more muscle as compared to the low (<=5) group (n = 13); the adjusted ratio (high versus low group) of the geometric mean RFCSA were (0.58, 95% CI 0.46-0.75) for right and (0.61, 95% CI 0.49-0.77) for left, both p < 0.001. mNUTRIC score obtained at admission to ICU can identify patients at risk of subsequent muscle loss.

PMID- 29581563 TI - A review of probiotic supplementation in healthy adults: helpful or hype? AB - Probiotic supplements have a positive impact on several health outcomes. However, the majority of published studies have focused on populations with specific health pathologies. Therefore, this study reviewed the current literature on the health effects of probiotic consumption in "healthy adults." The findings from this review may help guide consumers, researchers, and manufacturers regarding probiotic supplementation. Relevant literature published between 1990 and August 2017 was reviewed. Studies were included if they were experimental trials, included healthy adults, used live bacteria, and had accessible full-text articles published in English. Included studies were classified according to common foci that emerged. Forty-five studies were included in this review. Five foci emerged: gut microbiota changes (n = 15); immune system response (n = 16); lipid profile and cardiovascular disease risk (n = 14); gastrointestinal discomfort (n = 11); and female reproductive health (n = 4). Results suggest that probiotic supplementation in healthy adults can lead to transient improvement in gut microbiota concentration of supplement-specific bacteria. Evidence also supports the role of probiotics in improving immune system responses, stool consistency, bowel movement, and vaginal lactobacilli concentration. There is insufficient evidence to support the role of probiotics to improve blood lipid profile. Probiotic consumption can improve in the immune, gastrointestinal, and female reproductive health systems in healthy adults. However, this review failed to support the ability of probiotics to cause persistent changes in gut microbiota, or improve lipid profile in healthy adults. The feasibility of probiotics consumption to provide benefits in healthy adults requires further investigation. PMID- 29581564 TI - Prognostic impact of early nutritional support in patients affected by locally advanced and metastatic pancreatic ductal adenocarcinoma undergoing chemotherapy. AB - BACKGROUND/OBJECTIVES: The aim of this analysis was to determine the risk of malnutrition and the prognostic value of nutritional intervention in patients affected by pancreatic ductal adenocarcinoma (PDAC) undergoing chemotherapy. SUBJECTS/METHODS: Clinical-pathological and nutritional data were correlated with overall survival (OS) using a Cox model. Nutritional status was determined by Malnutrition Universal Screening Tool (MUST), body mass index, weight loss in the past 6 months, presence of nutrition-related symptoms, and current energy intake. Nutritional intervention included appropriate individual dietary counseling. RESULTS: Data from 109 patients were gathered (median age 63 years). The majority of patients (64.2%) presented a MUST value of >= 2, corresponding to a high risk of malnutrition. At multivariate analysis for OS in locally advanced and metastatic PDAC patients, the time between the diagnosis and the nutritional intervention (HR 2.22, p = 0.017), the performance status (HR 1.38, p = 0.075), the surgery of the primary (HR 5.89, p = 0.005), and the response to the first line (HR 5.9, p = 0.03) were independent significant predictors of outcome. Furthermore, a weight gain > 2% from the baseline weight was correlated with the time between the diagnosis and the nutritional intervention (p = 0.021): in patients receiving a nutritional support within 3 months from diagnosis, a 2% weight gain was associated with a 2-year OS benefit (50.3% vs. 33.0%, p = 0.04). CONCLUSIONS: This analysis suggests that the early nutritional support may contribute to influence the prognosis of patients affected by advanced PDAC undergoing chemotherapy. PMID- 29581565 TI - ARE-mediated decay controls gene expression and cellular metabolism upon oxygen variations. AB - Hypoxia triggers profound modifications of cellular transcriptional programs. Upon reoxygenation, cells return to a normoxic gene expression pattern and mRNA produced during the hypoxic phase are degraded. TIS11 proteins control deadenylation and decay of transcripts containing AU-rich elements (AREs). We observed that the level of dTIS11 is decreased in hypoxic S2 Drosophila cells and returns to normal level upon reoxygenation. Bioinformatic analyses using the ARE assessing algorithm AREScore show that the hypoxic S2 transcriptome is enriched in ARE-containing transcripts and that this trend is conserved in human myeloid cells. Moreover, an efficient down-regulation of Drosophila ARE-containing transcripts during hypoxia/normoxia transition requires dtis11 expression. Several of these genes encode proteins with metabolic functions. Here, we show that ImpL3 coding for Lactate Dehydrogenase in Drosophila, is regulated by ARE mediated decay (AMD) with dTIS11 contributing to ImpL3 rapid down-regulation upon return to normal oxygen levels after hypoxia. More generally, we observed that dtis11 expression contributes to cell metabolic and proliferative recovery upon reoxygenation. Altogether, our data demonstrate that AMD plays an important role in the control of gene expression upon variation in oxygen concentration and contributes to optimal metabolic adaptation to oxygen variations.

PMID- 29581567 TI - Gating interaction maps reveal a noncanonical electromechanical coupling mode in the Shaker K+ channel. AB - Membrane potential regulates the activity of voltage-dependent ion channels via specialized voltage-sensing modules, but the mechanisms involved in coupling voltage-sensor movement to pore opening remain unclear owing to a lack of resting state structures and robust methods to identify allosteric pathways. Here, using a newly developed interaction-energy analysis, we probe the interfaces of the voltage-sensing and pore modules in the Drosophila Shaker K+ channel. Our measurements reveal unexpectedly strong equilibrium gating interactions between contacts at the S4 and S5 helices in addition to those between S6 and the S4-S5 linker. Network analysis of MD trajectories shows that the voltage-sensor and pore motions are linked by two distinct pathways: a canonical pathway through the S4-S5 linker and a hitherto unknown pathway akin to rack-and-pinion coupling involving the S4 and S5 helices. Our findings highlight the central role of the S5 helix in electromechanical transduction in the voltage-gated ion channel (VGIC) superfamily.

AB - Superhydrophobicity is a remarkable evolutionary adaption manifested by several natural surfaces. Artificial superhydrophobic coatings with good mechanical robustness, substrate adhesion and chemical robustness have been achieved separately. However, a simultaneous demonstration of these features along with resistance to liquid impalement via high-speed drop/jet impact is challenging. Here, we describe all-organic, flexible superhydrophobic nanocomposite coatings that demonstrate strong mechanical robustness under cyclic tape peels and Taber abrasion, sustain exposure to highly corrosive media, namely aqua regia and sodium hydroxide solutions, and can be applied to surfaces through scalable techniques such as spraying and brushing. In addition, the mechanical flexibility of our coatings enables impalement resistance to high-speed drops and turbulent jets at least up to ~35 m s-1 and a Weber number of ~43,000. With multifaceted robustness and scalability, these coatings should find potential usage in harsh chemical engineering as well as infrastructure, transport vehicles and communication equipment.

AB - Although airway fibrosis and epithelial-mesenchymal transition (EMT) contribute to airway remodeling in chronic obstructive pulmonary disease (COPD), the mechanisms underlying their development have not been fully elucidated. In the present study, we aimed to assess heparin-binding epidermal growth factor (HB EGF) expression in the airways of patients with COPD and to elucidate the possible role of HB-EGF in the pathology of COPD. Sputum and lung tissue HB-EGF expression was evaluated in control subjects and patients with COPD. The relationships between HB-EGF expression, disease severity, collagen deposition (fibrosis), and EMT were investigated. In vitro, human bronchial epithelial (HBE) cells and lung fibroblast cells exposed to the recombinant HB-EGF, collagen deposition and EMT were assessed. We found that sputum HB-EGF expression was significantly increased in patients with COPD compared with non-smokers and smokers without COPD. There was a significant positive correlation between sputum HB-EGF and COPD assessment test (CAT) score. HB-EGF expression was significantly increased in the lung tissue samples of patients with COPD and associated with collagen deposition and N- and E-cadherin, and vimentin expression. In vitro, HB EGF promoted collagen production in lung fibroblasts. Moreover, HB-EGF induced the EMT process through induction of N-and E-cadherin, and vimentin expression in HBE cells. Collectively, HB-EGF induces airway remodeling by modulating airway fibrosis and pulmonary EMT, and contributes to the COPD severity. The current data may provide insight into the underlying pathogenesis of COPD, in which HB EGF has an important pathogenic role. PMID- 29581579 TI - Restoration of E-cadherin by PPBICA protects against cisplatin-induced acute kidney injury by attenuating inflammation and programmed cell death. AB - E-cadherin is a major component of tubular adherent proteins that maintain intercellular contacts and cell polarity in epithelial tissue. It is involved in pathological processes of renal cell carcinoma and fibrotic diseases via epithelial-mesenchymal transition. Although studies have shown E-cadherin is significantly downregulated in acute kidney injury (AKI), its function in AKI is unknown. Here, we evaluated cell damage and inflammation in cisplatin-stimulated tubular epithelial cell lines after disrupting E-cadherin and restoring it with PPBICA, a small molecule identified by high-throughput screening. We also determined the therapeutic potential of restoring E-cadherin in vivo. Results show cisplatin reduced E-cadherin expression both in mouse kidney and proximal tubular epithelial cell lines (mTECs). PPBICA restored E-cadherin levels, which increased cell viability while attenuating programmed cell death. This may be mediated via deactivation of the RIPK1/RIPK3 axis and decreased caspase3 cleavage. In addition, PPBICA suppressed inflammatory response in cisplatin treated mTECs, which correlated with suppressed NF-kappaB phosphorylation and promoter activity. In contrast, disruption of E-cadherin promoted cell damage and inflammation. PPBICA failed to further attenuate kidney damage in E-cadherin knockdown cells, indicating that PPBICA protects against mTECs through E-cadherin restoration. We also found that peritoneal injection of PPBICA in mice prevented loss of renal function and tubular damage by suppressing NF-kappaB-driven renal inflammation and RIPK-regulated programmed cell death. This was driven by restoration of E-cadherin in cisplatin nephropathy. Additionally, PPBICA attenuated cisplatin-induced kidney damage in an established AKI model, indicating its therapeutic potential in the treatment of AKI. In conclusion, E cadherin plays functional roles in tubule integrity, programmed cell death, and renal inflammation. Our results underscore the potential of E-cadherin restoration as a novel therapeutic strategy for AKI. PMID- 29581580 TI - Reduced expression of the H19 long non-coding RNA inhibits pancreatic cancer metastasis. AB - H19 is an oncofetal RNA expressed in the developing embryo as well as in bladder, breast, gastric, pancreatic, hepatocellular, and prostate cancers. Recent studies have shown that H19 enhances cancer invasion and metastasis; however, its roles in cancer remain controversial. In the current study, H19 exhibited the second largest increase (82.4-fold) and represented the only non-protein coding gene among 11 genes identified that were elevated over 10-fold in lung-metastasis derived pancreatic cancer cells compared with their parental cells using a mouse metastatic model. Subsequently, we further clarified the roles of H19 in pancreatic cancer growth and metastasis using in vitro and in vivo techniques. In situ hybridization showed that H19 was detected in 23 of 139 invasive ductal carcinomas (17%), and that H19 expression positively correlated with higher histological grades (P < 0.0001). Overexpression of H19 in PANC-1 pancreatic cancer cells induced higher motilities, whereas H19 inhibition using shRNA and siRNA showed opposite results; however, cell growth rates were not impacted. Intravenous injection of H19 shRNA vector-transfected PANC-1 cells yielded marked inhibition of metastasis in the liver and lungs of immunodeficient mice. These findings suggest that H19 has important roles in pancreatic cancer metastasis, and that inhibition of H19 represents a novel candidate for pancreatic cancer therapy. PMID- 29581581 TI - Stage-Rocked Electron Channeling for Crystal Orientation Mapping. AB - Microstructural analysis by crystal orientation mapping of bulk functional materials is an essential and routine operation in the engineering of material properties. Far and away the most successfully employed technique, Electron Backscattered Diffraction (EBSD), provides high spatial resolution information at the cost of limited angular resolution and a distorted imaging condition. In this work, we demonstrate a stage-rocked electron channeling approach as a low-cost orientation mapping alternative to EBSD. This is accomplished by automated electron channeling contrast imaging (ECCI) as the microscope stage physically tilts/rotates a sample through a reduced hemisphere of orientations followed by computational reconstruction of electron channeling patterns (ECP). Referred to as Orientation Mapping by Electron Channeling (OMEC), our method offers advantages in terms of local defect analysis, as it combines the advantages of selected area ECP (SACP) and ECCI. We also illustrate dynamic or "adaptive" sampling schemes to increase the throughput of the technique. Finally, we discuss the implications for sample analysis in which large 3D maps of ECCI images can be routinely constructed of challenging crystalline samples. As an electron channeling-based approach to orientation mapping, OMEC may open new routes to characterize crystalline materials with high angular and spatial resolution.

AB - ClC chloride channels and transporters are important for chloride homeostasis in species from bacteria to human. Mutations in ClC proteins cause genetically inherited diseases, some of which are likely to involve folding defects. The ClC proteins present a challenging and unusual biological folding problem because they are large membrane proteins possessing a complex architecture, with many reentrant helices that go only partway through membrane and loop back out. Here we were able to examine the unfolding of the Escherichia coli ClC transporter, ClC-ec1, using single-molecule forced unfolding methods. We found that the protein could be separated into two stable halves that unfolded independently. The independence of the two domains is consistent with an evolutionary model in which the two halves arose from independently folding subunits that later fused together. Maintaining smaller folding domains of lesser complexity within large membrane proteins may be an advantageous strategy to avoid misfolding traps. PMID- 29581584 TI - Biosynthesis of redox-active metabolites in response to iron deficiency in plants. AB - Iron is an essential but poorly bioavailable nutrient because of its low solubility, especially in alkaline soils. Here, we describe the discovery of a previously undescribed redox-active catecholic metabolite, termed sideretin, which derives from the coumarin fraxetin and is the primary molecule exuded by Arabidopsis thaliana roots in response to iron deficiency. We identified two enzymes that complete the biosynthetic pathway of fraxetin and sideretin. Chemical characterization of fraxetin and sideretin, and biological assays with pathway mutants, suggest that these coumarins are critical for iron nutrition in A. thaliana. Further, we show that sideretin production also occurs in eudicot species only distantly related to A. thaliana. Untargeted metabolomics of the root exudates of various eudicots revealed production of structurally diverse redox-active molecules in response to iron deficiency. Our results indicate that secretion of small-molecule reductants by roots may be a widespread and previously underappreciated component of reduction-based iron uptake. PMID- 29581585 TI - The dTAG system for immediate and target-specific protein degradation. AB - Dissection of complex biological systems requires target-specific control of the function or abundance of proteins. Genetic perturbations are limited by off target effects, multicomponent complexity, and irreversibility. Most limiting is the requisite delay between modulation to experimental measurement. To enable the immediate and selective control of single protein abundance, we created a chemical biology system that leverages the potency of cell-permeable heterobifunctional degraders. The dTAG system pairs a novel degrader of FKBP12F36V with expression of FKBP12F36V in-frame with a protein of interest. By transgene expression or CRISPR-mediated locus-specific knock-in, we exemplify a generalizable strategy to study the immediate consequence of protein loss. Using dTAG, we observe an unexpected superior antiproliferative effect of pan-BET bromodomain degradation over selective BRD4 degradation, characterize immediate effects of KRASG12V loss on proteomic signaling, and demonstrate rapid degradation in vivo. This technology platform will confer kinetic resolution to biological investigation and provide target validation in the context of drug discovery. PMID- 29581586 TI - Altered access to beneficial mutations slows adaptation and biases fixed mutations in diploids. AB - Ploidy varies considerably in nature. However, our understanding of the impact of ploidy on adaptation is incomplete. Many microbial evolution experiments characterize adaptation in haploid organisms, but few focus on diploid organisms. Here, we perform a 4,000-generation evolution experiment using diploid strains of the yeast Saccharomyces cerevisiae. We show that the rate of adaptation and spectrum of beneficial mutations are influenced by ploidy. Haldane's sieve effectively alters access to recessive beneficial mutations in diploid populations, leading to a slower rate of adaptation and a spectrum of beneficial mutations that is shifted towards dominant mutations. Genomic position also has an important role, as the prevalence of homozygous mutations is largely dependent on their proximity to a recombination hotspot. Our results demonstrate key aspects of diploid adaptation that have previously been understudied and provide support for several proposed theories. PMID- 29581587 TI - A biodiversity-crisis hierarchy to evaluate and refine conservation indicators. AB - The Convention on Biological Diversity and its Strategic Plan for Biodiversity 2011-2020 form the central pillar of the world's conservation commitment, with 196 signatory nations; yet its capacity to reign in catastrophic biodiversity loss has proved inadequate. Indicators suggest that few of the Convention on Biological Diversity's Aichi targets that aim to reduce biodiversity loss will be met by 2020. While the indicators have been criticized for only partially representing the targets, a bigger problem is that the indicators do not adequately draw attention to and measure all of the drivers of the biodiversity crisis. Here, we show that many key drivers of biodiversity loss are either poorly evaluated or entirely lacking indicators. We use a biodiversity-crisis hierarchy as a conceptual model linking drivers of change to biodiversity loss to evaluate the scope of current indicators. We find major gaps related to monitoring governments, human population size, corruption and threat-industries. We recommend the hierarchy is used to develop an expanded set of indicators that comprehensively monitor the human behaviour and institutions that drive biodiversity loss and that, so far, have impeded progress towards achieving global biodiversity targets.

We provide a phylogeny incorporating nearly all extant amphibians (7,238 species). Current amphibian diversity is composed of both older, depauperate lineages and extensive, more recent tropical radiations found in select clades. Frog and salamander diversification increased strongly after the Cretaceous-Palaeogene boundary, preceded by a potential mass-extinction event in salamanders. Diversification rates of subterranean caecilians varied little over time. Biogeographically, the Afro- and Neotropics harbour a particularly high proportion of Gondwanan relicts, comprising species with high evolutionary distinctiveness (ED). These high-ED species represent a large portion of the branches in the present tree: around 28% of all phylogenetic diversity comes from species in the top 10% of ED. The association between ED and imperilment is weak, but many species with high ED are now imperilled or lack formal threat status, suggesting opportunities for integrating evolutionary position and phylogenetic heritage in addressing the current extinction crisis. By providing a phylogenetic estimate for extant amphibians and identifying their threats and ED, we offer a preliminary basis for a quantitatively informed global approach to conserving the amphibian tree of life. PMID- 29581589 TI - The resilience of postglacial hunter-gatherers to abrupt climate change. AB - Understanding the resilience of early societies to climate change is an essential part of exploring the environmental sensitivity of human populations. There is significant interest in the role of abrupt climate events as a driver of early Holocene human activity, but there are very few well-dated records directly compared with local climate archives. Here, we present evidence from the internationally important Mesolithic site of Star Carr showing occupation during the early Holocene, which is directly compared with a high-resolution palaeoclimate record from neighbouring lake beds. We show that-once established there was intensive human activity at the site for several hundred years when the community was subject to multiple, severe, abrupt climate events that impacted air temperatures, the landscape and the ecosystem of the region. However, these results show that occupation and activity at the site persisted regardless of the environmental stresses experienced by this society. The Star Carr population displayed a high level of resilience to climate change, suggesting that postglacial populations were not necessarily held hostage to the flickering switch of climate change. Instead, we show that local, intrinsic changes in the wetland environment were more significant in determining human activity than the large-scale abrupt early Holocene climate events. PMID- 29581590 TI - Restoration science does not need redefinition. PMID- 29581591 TI - A guide to ancient protein studies. AB - Palaeoproteomics is an emerging neologism used to describe the application of mass spectrometry-based approaches to the study of ancient proteomes. As with palaeogenomics (the study of ancient DNA), it intersects evolutionary biology, archaeology and anthropology, with applications ranging from the phylogenetic reconstruction of extinct species to the investigation of past human diets and ancient diseases. However, there is no explicit consensus at present regarding standards for data reporting, data validation measures or the use of suitable contamination controls in ancient protein studies. Additionally, in contrast to the ancient DNA community, no consolidated guidelines have been proposed by which researchers, reviewers and editors can evaluate palaeoproteomics data, in part due to the novelty of the field. Here we present a series of precautions and standards for ancient protein research that can be implemented at each stage of analysis, from sample selection to data interpretation. These guidelines are not intended to impose a narrow or rigid list of authentication criteria, but rather to support good practices in the field and to ensure the generation of robust, reproducible results. As the field grows and methodologies change, so too will best practices. It is therefore essential that researchers continue to provide necessary details on how data were generated and authenticated so that the results can be independently and effectively evaluated. We hope that these proposed standards of practice will help to provide a firm foundation for the establishment of palaeoproteomics as a viable and powerful tool for archaeologists, anthropologists and evolutionary biologists. PMID- 29581592 TI - Passively Driven Probe Based on Miniaturized Propeller for Intravascular Optical Coherence Tomography. AB - Optical coherent tomography (OCT) has enabled clinical applications ranging from ophthalmology to cardiology that revolutionized in vivo medical diagnostics in the last few decades, and a variety of endoscopic probes have been developed in order to meet the needs of various endoscopic OCT imaging. We propose a passive driven intravascular optical coherent tomography (IV-OCT) probe in this paper. Instead of using any electrically driven scanning device, the probe makes use of the kinetic energy of the fluid that flushes away the blood during the intravascular optical coherence tomography imaging. The probe converts it into the rotational kinetic energy of the propeller, and the rotation of the rectangular prism mounted on the propeller shaft enables the scanning of the beam. The probe is low cost, and enables unobstructed stable circumferential scanning over 360 deg. The experimental results show that the probe scanning speed can exceed 100 rotations per second (rps). Spectral-domain OCT imaging of a phantom and porcine cardiac artery are demonstrated with axial resolution of 13.6 MUm, lateral resolution of 22 MUm, and sensitivity of 101.7 dB. We present technically the passively driven IV-OCT probe in full detail and discuss how to optimize the probe in further. PMID- 29581594 TI - Comparison of ultrasound with hysteroscopic and histological findings for intrauterine assessment. AB - INTRODUCTION: Hysteroscopy with biopsy is a common diagnostic and therapeutic method in gynaecology. Its use is preceded by ultrasound examination. The success rate of predicting intrauterine findings based on ultrasound has not been assessed in the Czech Republic for a long time. In the meantime, there have been technological improvements in ultrasound devices. METHOD: Patients indicated for hysteroscopy underwent ultrasound examination and their medical history was recorded. The percentage agreement between ultrasound and histopathological findings was assessed. The secondary goal was to find an easier way of describing ultrasound findings in gynaecological practice. RESULTS: The study comprised 255 patients. In 15 cases, endometrial carcinoma was confirmed by hysteroscopy and histopathological examination. Of these, malignancies were suspected based on previous ultrasound scans in 11 patients. In 95 cases, intrauterine polyps were detected. The success rate for predicting polyps by ultrasound examination was 65.1%. The agreement between ultrasound and hysteroscopic/histopathological findings was 72%. The secondary goal of making the description of the uterine cavity easier was not fulfilled. The prediction percentages for the criteria were low. The incidence of pathological findings in ultrasound findings labelled as anechogenic was 4.8%, suggesting a high negative predictive value. CONCLUSION: In spite of the better resolution of new ultrasound devices, their predictive value remains limited. Findings that are suspicious in ultrasound should be confirmed by hysteroscopy with biopsy. PMID- 29581593 TI - L3MBTL2 orchestrates ubiquitin signalling by dictating the sequential recruitment of RNF8 and RNF168 after DNA damage. AB - Cells respond to cytotoxic DNA double-strand breaks (DSBs) by recruiting DNA repair proteins to the damaged site. This recruitment is dependent on ubiquitylation of adjacent chromatin areas by E3 ubiquitin ligases such as RNF8 and RNF168, which are recruited sequentially to the DSBs. However, it is unclear what dictates the sequential order and recruits RNF168 to the DNA lesion. Here, we reveal that L3MBTL2 (lethal(3)malignant brain tumour-like protein 2) is the missing link between RNF8 and RNF168. We found that L3MBTL2 is recruited by MDC1 and subsequently ubiquitylated by RNF8. Ubiquitylated L3MBTL2, in turn, facilitates recruitment of RNF168 to the DNA lesion and promotes DNA DSB repair. These results identify L3MBTL2 as a key target of RNF8 following DNA damage and demonstrates how the DNA damage response pathway is orchestrated by ubiquitin signalling. PMID- 29581595 TI - Elevated DNA methylation in malignant tumors of the sinonasal tract and its association with patient survival. AB - BACKGROUND: Epigenetic modifications have been recognized as an important mechanism underlying carcinoma progression. DNA methylation plays an important role in cancer biology and represents potentially heritable changes in gene expression that do not involve DNA sequence. The aim of this study was to investigate promoter methylation of selected genes in sinonasal carcinoma by comparison with noncancerous sinonasal tissue. METHODS: To search for epigenetic events (methylation in 25 tumor suppressor genes) we used MS-MLPA (Methylation specific multiplex ligation-dependent probe amplification) to compare methylation status of 59 formalin fixed, paraffin embedded tissue samples of sinonasal carcinomas with 18 control samples. The most important changes in methylation were confirmed using MSP (Methylation specific PCR). Detected alterations in methylation were compared with clinicopathological characteristics. RESULTS: Using a 20% cut-off for methylation (MS-MLPA), we found significantly higher methylation in GATA5 (P=0.0005), THSB1 (P=0.0002) and PAX5 (P=0.03) genes in the sinonasal cancer group compared to the control group. Methylation in five or more genes was associated with impaired overall survival (P=0.017). CONCLUSION: These findings provide evidence that alterations in methylation profile may be one of the major mechanisms in sinonasal carcinogenesis. In addition, changes in methylation could potentially be used as prognostic factors of sinonasal carcinoma and may have implications for future individualized therapy based on epigenetic changes. PMID- 29581596 TI - Why Is Burnout a Taboo? PMID- 29581597 TI - Stability of 2 mg/mL Adenosine Solution in Polyvinyl Chloride and Polyolefin Infusion Bags. AB - Adenosine is a potent endogenous mediator of vasodilation. Compounded sterile solutions of adenosine are used in cardiac catheterization lab to perform stress tests on the heart. These tests are used to determine the fractional flow reserve (FFR) and are commonly used in the management and diagnosis of cardiovascular conditions. The purpose of this study was to assess the physical and chemical stability of 2 mg/mL adenosine in 0.9% Sodium Chloride Injection, USP in polyvinyl chloride [PVC]) and polyolefin infusion bags stored at room temperature (20 degrees C-25 degrees C) and under refrigeration (2 degrees C-8 degrees C). The compounding and analytical methods used in this study were very similar to those described in the prior publications from the authors' laboratory. To ensure a uniform starting concentration of all stability samples, a batch of 2 mg/mL adenosine solution was prepared and then packaged into empty PVC and polyolefin infusion bags. These stability samples were prepared in triplicate for each bag type and storage temperature (a total of 12 samples). The infusion bag samples were assessed for stability immediately after preparation and after 1 day, 3 days, 7 days, and 14 days. At each time point, the infusion bags were first visually inspected against a light background for color change, clarity, and particulates. Aliquots were drawn from each sample at each time point for pH analysis and high-performance liquid chromatography (HPLC) analysis. Over 14 days of storage at room temperature or refrigeration, no considerable change in visual appearance or pH was observed in any bags. All samples retained 90% to 110% of the initial drug concentration. No significant degradation peaks were observed in the HPLC chromatograms.

PMID- 29581599 TI - New Medications in the Treatment of Acute Decompensated Heart Failure. AB - Acute decompensated heart failure is a sudden worsening of heart failure symptoms, typically resulting in peripheral edema and dyspnea as a result of pulmonary congestion. Acute decompensated heart failure is responsible for over 1 million hospitalizations every year. Current pharmacologic therapy is limited in its options. Despite an improved survival rate, statistic still suggests that about 50% of patients die within 5 years of diagnosis. New pharmacologic agents aim to improve efficacy by targeting previously unexplored physiological pathways. PMID- 29581600 TI - The Prescription Drug User Fee Act: Cause for Concern? AB - The Prescription Drug User Fee Act (PDUFA) was originally enacted into law in 1992. PDUFA provides the Food and Drug Administration (FDA) with needed revenue in the form of various fees paid by drug and biologic manufacturers. The FDA utilizes this revenue to streamline the review and approval process for medications. Since the enactment of PDUFA, the median approval time for priority new drug applications and biologics license applications has reduced significantly. The FDA views PDUFA as a successful program that provides a consistent revenue stream to the agency, improves access to medications for patients, and allows industry to have a more predictable product review timeline. However, critics of PDUFA cite concerns including the potential for a lack of FDA independence and medication safety issues involving drugs approved after the existence of PDUFA.

AB - Purpose: The purpose of this article is to share experiences after the development of a health-system pharmacy administration residency with a MS degree and express the need for additional programs in nonacademic medical center health system settings. Summary: Experiences with the development and implementation of a health-system pharmacy administration residency at a large community teaching hospital are described. Resident candidates benefit from collaborations with other health-systems through master's degree programs and visibility to leaders at your health-system. Programs benefit from building a pipeline of future pharmacy administrators and by leveraging the skills of residents to contribute to projects and department-wide initiatives. Tools to assist in the implementation of a new pharmacy administration program are also described and include rotation and preceptor development, marketing and recruiting, financial evaluation, and steps to prepare for accreditation. Conclusion: Health-system pharmacy administration residents provide the opportunity to build a pipeline of high-quality leaders, provide high-level project involvement, and produce a positive return on investment (ROI) for health-systems. These programs should be explored in academic and nonacademic-based health-systems. PMID- 29581604 TI - Breadth of Statistical Training Among Pharmacy Residency Programs Across the United States. AB - Background: Pharmacy residents' knowledge of biostatistics is a self-identified deficit. Objective: To describe statistical training practices across postgraduate year 1 (PGY1) pharmacy residency programs and correlate training practices with residency program directors' (RPDs) confidence in their residents' statistical abilities. Methods: A 13-item survey was sent to PGY1 RPDs and included questions regarding respondents' institution, program characteristics, type and amount of statistical training offered and desired, as well as performance of statistics, resident project publication rates, and RPDs' confidence in residents' statistical abilities. Results: Of the 1054 RPDs invited to participate in the survey, 202 (19.7%) surveys were completed. Nearly 25% of PGY1 pharmacy residency programs in this sample offered no statistical training to their residents. The most common types of training were study design considerations/selecting statistical tests (64.9%), descriptive statistics (59.9%), and database development/data manipulation (46.6%). The majority (60.9%) of RPDs had low confidence in their residents' abilities to perform their own statistical analysis. After adjusting for significant covariates, residents receiving complex statistical training (odds ratio [OR]: 6.76; 95% confidence interval [CI]: 2.7-24.9) and a publication rate >50% (OR: 5.63; 95% CI: 1.61 19.69) were associated with higher RPD confidence in residents' abilities to perform statistical analyses. Conclusion: The sample of programs in this survey indicates that statistical training for many residents may be limited, and many RPDs are not confident in their residents' abilities to perform statistical analysis of research projects. Statistical training and opportunities to enhance research skills may be an area for future growth in pharmacy residency training programs. PMID- 29581605 TI - Antihypertensive Prescription Pattern and Compliance to JNC 7 and JNC 8 at Tertiary Care Government Hospital, Hyderabad, India: A Cross-sectional Retrospective Study. AB - Background: The monitoring of hypertension treatment can provide insight into the rational drug use pattern. The objective of this study was to examine the antihypertensive medication use among South Indian adults with hypertension in compliance with the hypertension treatment guidelines (Seventh Joint National Committee [JNC 7] and JNC 8). Methods and Results: A total of 550 hypertensive people aged >25 years were included in this retrospective cross-sectional study. The order of drugs prescribed in the year 2012 was beta blockers (BB) > calcium channel blockers (CCB) > CCB + BB > angiotensin receptor blockers (ARB) > angiotensin-converting enzyme inhibitors (ACEI) > thiazide diuretics, whereas in the year 2014, the order has changed drastically, namely, ACEI > CCB > ARB > BB > thiazide diuretics (P < .001). Most notably, there was a large increase in the use of monotherapy (from 56.9% to 82.5%, P < .001). The usage of BB has simply moved from the first position to the last position in concordance with JNC 8 guidelines, whereas use of thiazide diuretics was found to be the least preferred drug in the 2012 prescriptions, thus deviating from JNC 7 guidelines. The use of generic names (28.3% vs 11.3%) and National List of Essential Medicines (NLEM) compliance (79.3% vs 60.9%) were significantly more in the calendar year 2012 than in the calendar year 2014 (P < .001). Conclusions: Antihypertensive medication use has gone through wide variations among south Indian adults with hypertension. Combination therapy regimens must be adopted as per the guidelines for achievement of blood pressure goals. PMID- 29581606 TI - Changes in Pharmacy Residency Training Design Between 2012 and 2017: A Perspective of Academic Medical Centers. AB - Purpose:The role of health-system pharmacists continues to expand, and this area of pharmacy practice increasingly requires augmented baseline training. It is unclear how Post Graduate Year 1 (PGY-1) pharmacy residencies may be changing to meet these needs.The objectives of our survey were to describe PGY-1 pharmacy residency program design among academic medical centers, characterize program changes enacted over 5-year period, and describe career paths among PGY-1 pharmacy residency graduates. Methods: A 32-item questionnaire was developed independently, which was reviewed and validated by 4 residency program directors. The survey was uploaded to an online survey tool and sent electronically to residency program directors of 109 Vizient academic medical centers with PGY-1 pharmacy residency programs. Residency program directors were identified from a list of Vizient-participating hospitals. The survey was re-sent at 2-week intervals on 4 occasions to improve response rates. SPSS version 23.0 was used to analyze the data. Results: Overall, 49 (45%) of hospitals responded to the survey. Survey responses showed statistically significant increases over the 5 year survey period in the following areas: the number of PGY-1 resident positions offered (P = .001), percent of time spent on teaching experiences (P = .001), and percentage of PGY-1 residents pursuing PGY-2 or fellowship training (P = .026). Conclusion: We found that PGY-1 pharmacy residency programs at Vizient academic medical centers have undergone limited changes over the 5-year survey period and substantial variation exists between program designs. The most common change to program design was an increase in the percentage of time residents spend on teaching experiences. There was an increase in residents pursuing PGY-2 or fellowship training, which may suggest a shift toward increased specialization in clinical pharmacy practice or may reflect changes in the availability of job opportunities. PMID- 29581607 TI - Incidence of Hypoglycemia in Burn Patients: A Focus for Process Improvement. AB - Background: Glycemic control in burn patients is critical for reducing infection and mortality. Objective: This study was conducted to assess the incidence and outcomes of hypoglycemia during continuous insulin infusions (CII). Methods: This institutional review board-approved study was a retrospective, single burn center, electronic chart review. Patients admitted between January 1, 2013, and October 31, 2014, who received a CII were included. Patients with incomplete data or who received <24 hours of CII were excluded. Results: Thirty-eight patients met inclusion criteria; 6 were excluded. The average patient was a 52-year-old Caucasian male with a 33% total body surface area burn and an acute physiology and chronic health evaluation (APACHE) II score of 20.Hypoglycemia was present for 87 of 6540 hours of CII therapy (1.1%). Two-thirds experienced a serum glucose <70 mg/dL and half <60 mg/dL. The most commonly assessed reasons for the hypoglycemic episodes were protocol violations (47%) and glucose variability (30%). After multivariable logistic regression, only history of diabetes remained a statistically significant risk factor with an odds ratio of 15.4 (95% confidence interval: 2.5-95.1). Four different CII protocols were prescribed. All protocols had a high glucose variability, as assessed by hours / day within goal range (13.1 +/- 2.5, 14.1 +/- 3.1, 14.3 +/- 2.4, 9.8; P = .282). Conclusion: The amount of different protocols likely contributed to protocol violations and glucose variability. Our data demonstrate the need to create and consolidate usage to a single protocol in attempts to improve glycemic control. PMID- 29581608 TI - Physical Compatibility of Micafungin With Sodium Bicarbonate Hydration Fluids Commonly Used With High-Dose Methotrexate Chemotherapy. AB - Purpose: The purpose of this study was to determine the physical compatibility of micafungin with commonly used concentrations of sodium bicarbonate hydration fluids administered via a Y-site connected to a central venous catheter (Y site/CVC). Methods: Micafungin sodium (evaluated concentration of 1.5 mg/mL) was combined in a 3:1 (vehicle:drug) ratio with the following commonly used hydration vehicles: 40 mEq/L sodium bicarbonate in 5% dextrose in water with 1/4 normal saline (40SB-D5W-1/4NS), 75 mEq/L sodium bicarbonate in D5W (75SB-D5W), and 154 mEq/L sodium bicarbonate in D5W (154SB-D5W). A 3:1 ratio was used based on the flow rates (typically 125 mL/m2/h for bicarbonate-containing vehicles and 50 mL/h for micafungin) of the corresponding solutions in a clinical setting. Visual observations recorded to determine physical compatibility included visual inspection against different backgrounds (unaided, black, and white). Other physical observations were as follows: odor, evolution of gas, pH, and turbidity immediately recorded after mixing and at specified time points up to 2 hours. Evaluations at each time point were compared against baseline observation values at Time 0. Results: All combinations tested were found to be compatible up to 2 hours. Time points beyond 2 hours cannot be safely verified as compatible. Conclusion: Micafungin may be administered safely using a Y-site/CVC delivery system with all the vehicles tested in this study. PMID- 29581609 TI - Surgical outcomes of decompressive laminoplasty with spinous process osteotomy to treat lumbar spinal stenosis. AB - Decompressive laminoplasty with spinous process osteotomy (LSPO) was developed as a less invasive procedure for lumbar decompression by Weiner et al. There are few reports extensively highlighting the surgical outcomes of LSPO. The purpose of this study was to evaluate the surgical outcomes of LSPO for lumbar spinal stenosis (LSS). In total, 23 patients with LSS were studied. All patients were followed up for more than 2 years. The Japanese Orthopedic Association (JOA) scores, the recovery rate (RR) of JOA scores, Visual analog scale (VAS) scores, responses to the JOA Back Pain Evaluation Questionnaire (JOABPEQ), sagittal alignment and segmental motion following LSPO were assessed preoperatively and 2 years postoperatively. Postoperative paravertebral muscle atrophy and bone union rates between the spinous process and the residual laminae were assessed. Preoperative and 2-year postoperative JOA scores were 13.0 points and 24.7 points, respectively (p<0.001). With respect to JOABPEQ, significant improvements were observed in pain-related disorders (p<0.05), walking ability (p<0.01), social life function (p<0.05), and mental health (p<0.05) dimensions. There were no significant differences between preoperative and 2-year postoperative sagittal alignment and range of motion. The degree of the paravertebral muscle atrophy at 2 years postoperatively was 23.0 % at spread side and 9.6 % at nonspread side (p<0.01). The fusion rate of the spinous process with the arcus vertebrae was 87%. This result reveals that LSPO could acquire the reconstruction of posterior supporting structures. We demonstrated that LSPO could be a one of the surgical options for LSS. PMID- 29581610 TI - Estimated costs for treatment and prophylaxis of newborn vitamin K deficiency bleeding in Tashkent, Uzbekistan. AB - Vitamin K deficiency bleeding (VKDB) is a preventable cause of infant mortality and long-term morbidity through the world. This study aimed to demonstrate the costs of VKDB treatment estimated from the hospital records in Tashkent, Uzbekistan, as well as the prophylaxis costs for mass vitamin K medication. Subjects were 50 patients with no operation and 50 patients who had received a brain operation, consecutively enrolled from 180 cases diagnosed at Republican Research Center of Emergency Medicine in 2014. In that year, an additional 22 VKDB patients were found in Tashkent; the incidence of VKDB was 478/100,000 among 42,225 newborns. The prophylaxis costs for all newborns in Tashkent were estimated under a plausible condition. The average age at admission was 43.2 days among 100 patients (67 boys and 33 girls) with birth weight from 2,600 g to 3,800 g (3,105 g on average). The great majority of patients (92.0%) were breastfed; 89.5% in boys and 97.0% in girls. Average treatment cost per VKDB patient was 365 USD for the operated and 285 USD for the non-operated. Total expenses of the 202 patients were estimated to be 64,603 USD. A single prophylaxis was estimated to cost 1.24 USD, totaling 52,359 USD for the prophylaxis of 42,225 newborns. Since the reduction of VKDB incidence through prophylaxis is considered to be higher than 78.5% (52,359/64,603), provision of prophylaxis services would reduce the total costs of VKDB treatment in Uzbekistan, where prophylaxis is not provided. PMID- 29581611 TI - Obesity does not affect peri- and postoperative outcomes of transabdominal laparoscopic adrenalectomy. AB - Laparoscopic adrenalectomy is the gold standard procedure for most adrenal tumors. Obesity is considered as a risk factor for surgical complications. This study aimed to evaluate whether obesity affects peri- and postoperative outcomes of transabdominal laparoscopic adrenalectomy using body mass index (BMI). This retrospective study included 98 patients who underwent transabdominal laparoscopic adrenalectomy between January 2011 and December 2016. We divided the patients into 2 groups: non-obese group (BMI < 25 kg/m2) and obese group (BMI >= 25 kg/m2). We assessed perioperative outcomes and postoperative complications between the groups. A total of 98 patients were analyzed (70 without obesity and 28 with obesity). There were no significant differences between the non-obese and obese groups regarding operative time (111 vs 107 min; p = 0.795), blood loss (3.5 vs 3.5 ml; p = 0.740), rate of placement of additional trocars (14.3% vs 17.9%; p = 0.657), rate of open conversion (2.6% vs 3.6%; p = 0.853), and postoperative length of hospital stay (6 vs 5 days; p = 0.237). Furthermore, obesity was not a significant risk factor for postoperative complications (postoperative bleeding, wound infection, and pneumonia). There are no significant differences in peri- and postoperative outcomes of transabdominal laparoscopic adrenalectomy in patients with obesity compared with those without obesity. Transabdominal laparoscopic adrenalectomy is feasible and safe for patients with obesity. PMID- 29581612 TI - Association between the perspective of adult inpatients with digestive cancer regarding the nursing service and their quality of recovery on postoperative day 3. AB - Although qualitative research that focuses on inpatients' experience immediately after surgery has continued to elucidate the efficacy of the nursing service for postoperative recovery, there has been little quantitative research. Our aim was to quantitatively clarify the association between inpatients' perception of the nursing service and the quality of postoperative recovery. Seventy-one digestive cancer patients who underwent surgery were recruited. Participants completed two self-administered questionnaires, including the Japanese version of the 40-item postoperative Quality of Recovery scale (QoR-40J) and the Nursing Service Quality Scale for Japan (NURSERV-J) which has 22 items and five dimensions (tangibles, reliability, responsiveness, assurance, and empathy) on postoperative day 3. There were significant positive associations between the global scores of the NURSERV-J and the QoR-40J. The global score of the QoR-40J was compared between patients who gave full marks for each dimension of the NURSERV-J (the entirely satisfied group) and those who did not (the not entirely satisfied group). The entirely satisfied groups regarding tangibles, reliability and responsiveness had a significantly higher global score for the QoR-40J than the respective not entirely satisfied groups. Adjusted for age, gender, operative procedure, and duration of surgery, the entirely satisfied groups regarding tangibles and responsiveness had a significant higher global score for the QoR-40J than the respective not entirely satisfied groups. Patients who perceived that they had received a nursing service of high quality were likely to attain a high quality of postoperative recovery. Nursing services related to tangibles, reliability, and responsiveness especially contributed to postoperative recovery. PMID- 29581613 TI - Intra-articular platelet-rich plasma (PRP) injections for treating knee pain associated with osteoarthritis of the knee in the Japanese population: a phase I and IIa clinical trial. AB - Intra-articular platelet-rich plasma (PRP) injection has been found to be effective for treating osteoarthritis in patients from Western countries; however, the safety and efficacy of PRP have not been sufficiently investigated in Japanese patients. The present study aimed to evaluate the safety and feasibility of intra-articular PRP injection in Japanese patients with knee osteoarthritis. PRP without white blood cells was prepared using a single-spin centrifuge (PRGF-Endoret; BTI Biotechnology Institute, Vitoria, Spain). A 6-mL PRP volume was injected in the knee joint three times at 1 week intervals. All patients were prospectively evaluated before intervention and at 1, 3, and 6 months after the treatment. Adverse events, the Visual Analog Scale (VAS) pain score, Japanese Knee Osteoarthritis Measure (JKOM) score and Japanese Orthopedic Association score were evaluated. Ten patients (all women; average age, 60.6 years) were treated. Only minor adverse events after injection were noted, and symptoms resolved within 48 hours after the injection. The average VAS pain scores were 71.6 mm and 18.4 mm at baseline and the 6-month follow-up, respectively (P < 0.05). At the 6-month follow-up, 80% of patients had a decrease in the VAS pain score of 50% or more. The average JKOM scores were 35.2 and 14.3 at baseline and at the 1-month follow-up, respectively (P < 0.05). Intra articular PRP injection likely represents a safe treatment option for Japanese patients with mild-to-moderate knee osteoarthritis, and has the potential to relieve pain for up to 6 months, but further study is needed to verify the efficacy. PMID- 29581614 TI - Effect of spinal tap test on the performance of sit-to-stand, walking, and turning in patients with idiopathic normal pressure hydrocephalus. AB - The aim of the study was to investigate the effect of the spinal tap test on sit to-stand (STS), walking, and turning and to determine the relationship among the outcome measures of STS, walking, and turning in patients with iNPH. Twenty-seven patients with clinical symptoms of iNPH were objectively examined for STS, walking, and turning by the Force Distribution Measurement (FDM) platform connected with a video camera. Assessments were performed at before and 24 hours after spinal tap. Motor abilities were assessed by the STS time, time of walking over 3 meters, and time and number of steps when turning over 180 degrees. Significant improvements were found in the STS time (p = 0.046), walking time (p = 0.048), and turning step (p = 0.001). In addition, turning time was improved but not statistically significant (p = 0.064). Significant relationships were found among all outcome measures (p < 0.001). The relationship among these outcome measures indicated that the individuals had similar ability levels to perform different activities. This may serve as a new choice of outcome measures to evaluate the effect of intervention in different severity levels of patients with iNPH. PMID- 29581615 TI - Factors related to sense of coherence in adult patients with Type 2 diabetes. AB - The influence of a diabetic person's sense of burden and blood sugar control through sense of coherence (SOC) on self-management has yet to be sufficiently clarified. The purpose of this study was to examine the utility of salutogenesis, which has sense of coherence at its core, for the self-management of patients with type 2 diabetes. A total of 258 questionnaires were distributed to patients who were seen at one of three hospitals in an urban area in Japan, after obtaining consent from the patient. They were between 20 and 75 years old and regularly received care. Of the 185 responses, 177 were valid. The responses were analyzed by referring to the framework of salutogenesis, and the relationship between patient characteristics, SOC, the Problem Areas In Diabetes survey (PAID), and glycosylated hemoglobin (HbA1c) were studied with structural equation modeling (SEM). SOC had a main effect on PAID scores and an indirect effect on HbA1c. Moreover, age influenced SOC positively. The SOC of patients with type 2 diabetes in the present study was comparatively high. These observations suggest a direct effect of SOC on reducing the sense of burden from having diabetes and an indirect effect on decreasing HbA1c. This research suggested the possibility that diabetes can be controlled by improving SOC. PMID- 29581616 TI - Medical clerks in a national university hospital: improving the quality of medical care with a focus on spinal surgery. AB - In our institution, which is a national university hospital, medical clerks were introduced in 2009 to improve the doctor's working environment. Seventeen clerks were assigned to 9 separate departments and the work content differed greatly among departments, but sufficient professional work was not done efficiently. The purpose of this study is to investigate the effects of the work of medical clerks on improvement of medical quality in recent years. In 2011, we established a central clerk desk on our outpatient floor to improve efficiency and centralize the clerk work. Since 2013, periodic education of clerks on spine disease has been provided by spine doctors, and this has facilitated sharing of information on spinal surgery from diagnosis to surgical treatment. This has allowed medical clerks to ask patients questions, leading to more efficient medical treatment and a potential reduction of doctors' work. In 2016, a revision of the insurance system by the Ministry of Health, Labour and Welfare of Japan increased the amount of medical work that clerks can perform, and it became possible to increase the number of medical clerks. Currently, we have 30 medical clerks, and this has allowed establishment of new clerk desks in other departments to handle patients. A training curriculum will be developed to reduce the burden on doctors further and to improve the quality of medical treatment. PMID- 29581617 TI - National survey of international electives for global health in undergraduate medical education in Japan, 2011-2014. AB - Interest in global health in medical education is increasing in Western countries, whereas data from non-Western countries is scarce. Here, we conducted a nationwide study of international clinical electives at Japanese medical schools from 2011 to 2013. We constructed a 28-item cross-sectional survey in Japanese to investigate the rate and characteristics of both Japanese students going abroad and international students coming on exchange to Japan. The surveys were sent to the administrative offices of all 80 Japanese medical schools in each of the three years, through the Japan Medical Education Foundation. All 80 medical schools responded to the questionnaire (response rate, 100%). An average of 70 of the 80 medical universities provided exchange programs across the three years to allow students to travel abroad as part of the school curriculum and obtain academic credit. The schools provided support in the form of in- and outside-class preparatory programs, tuition fee exemptions and housing. The most popular destinations for Japanese students going abroad were Europe and North America, which may reflect the desire of Japanese students to acquire medical knowledge or experience through exposure to the English language. In contrast, the most common countries of origin of international exchange students coming to Japan were Asian countries such as South Korea, Thailand and Taiwan, with pediatrics being the most popular elective. Foreign exchange programs are becoming increasingly incorporated into the Japanese medical education curriculum and can help to strengthen international partnerships and collaborations. PMID- 29581618 TI - Maxillary sinus carcinoma outcomes over 60 years: experience at a single institution. AB - Advances in the diagnosis and treatment of patients with maxillary sinus carcinoma have improved patient prognosis. This study investigated changes in demographic and clinical characteristics, treatment methods, and outcomes of patients with maxillary sinus carcinomas during three different 10-year periods spanning 60 years at our university hospital. Of the 233 patients with maxillary sinus carcinomas managed at Nagoya University Hospital, 135 were treated between 1951 and 1960 (first period), 35 between 1981 and 1990 (second period), and 63 between 2003 and 2012 (third period). Patient age, sex, TN classifications, treatment methods, and survival rates were compared among patients treated during these time periods. Of the 135, 35, and 63 patients with maxillary sinus carcinomas treated during these time periods, 86 (63.7%), 21 (51.4%), and 48 (76.2%), respectively, were men; 14 (10.4%), six (17.1%), and 14 (22.2%), respectively, were aged >=70 years; and 135 (100%), 28 (80.0%), and 43 (68.3%), respectively, were treated surgically. The 5-year overall survival rates in patients treated during the first, second, and third periods were 29.7%, 44.3%, and 57.5%, respectively. These findings indicated that advances in the diagnosis and treatment of patients with maxillary sinus carcinoma, including computed tomography and craniofacial resection, have contributed to improvements in patient survival rates. PMID- 29581619 TI - Identifying the social capital influencing diabetes control in Japan. AB - The number of patients with diabetes is increasing in Japan. Recently, Social capital (SC) has received increasing attention as a factor influencing health conditions. In the US, the relation between SC and diabetes control has been reported, but little attention has been paid to this connection in Japan. Three SC questionnaires, entitled "trust in people in a community," "social support," and "social relationships," were constructed. The subjects were adult patients with type 2 diabetes. Information on diabetic conditions, such as HbA1c, self attainment of diet (SAD) and exercise (SAE), and complications were collected. The reliability coefficients for the SC questionnaire and factor analysis of SC were conducted. Multiple and logistic regressions were used to identify the influence of SC on diabetes control. Sixty-five patients participated in this study. The questionnaires "social support" and "social relationships" were adopted to measure Cronbach alpha coefficient. Factor analysis extracted the factors "hope to be helped (HH)," "participation in favorite events (PFE)," "sense of belonging (SB)," and "social movement (SM)." HbA1c was positively correlated with HH (P < 0.05). SAD and SAE were negatively correlated with HH (P < 0.05). SAE was positively correlated with PFE (P < 0.05). PFE reduced complication risks (P < 0.05). HH includes amae, which negatively affected self efficacy that correlates with diabetes control. Therefore, higher HH might cause higher levels of HbA1c. PFE reduces distress and contributes to glucose control. Reduced distress through PFE might prevent complications. HH and PFE were identified as SC that influences diabetes control. PMID- 29581620 TI - Genome-wide association study for pollinosis identified two novel loci in interleukin (IL)-1B in a Japanese population. AB - The number of pollinosis patients in Japan has significantly increased over the past 20 years. The majority of genome-wide association studies (GWAS) on pollinosis have been conducted in subjects of European descent, with few studies in Japanese populations. The aim of our GWAS was to identify genetic loci associated with self-reported pollinosis in a Japanese population and to understand its molecular background using a combination of single nucleotide polymorphisms (SNPs) and gene- and pathway-based analyses. A total of 731 and 560 individuals who were recruited as participants of the Japan Multi-Institutional Collaborative Cohort Study participated in the discovery and replication phases, respectively. The phenotype of pollinosis was based on the information from a self-administered questionnaire. In the single-SNP analysis, four SNPs (rs11975199, rs11979076, rs11979422, and rs12669708) reached suggestive significance level (P < 1 * 10-4) and had effects in the same direction in both phases of the study. The pathway-based analysis identified two suggestive pathways (nucleotide-binding oligomerization domain -like receptor and tumor necrosis factor signaling pathways). Both rs1143633 and rs3917368 in the interleukin-1B gene showed associations in the retrace (from pathway to gene and SNP) analysis. We performed single-SNP, gene, and pathway analysis and shed light on the molecular mechanisms underlying pollinosis in a Japanese population. PMID- 29581621 TI - Clinical significance of gastrointestinal patency evaluation by using patency capsule in Crohn's disease. AB - Capsule endoscopy (CE) enables noninvasive visualization of the small bowel in Crohn's disease (CD), but should not be conducted in patients with bowel obstruction. Patency capsule (PC) can be ingested before conducting the CE examination to ensure patency of the gastrointestinal (GI) tract. This study aimed to evaluate the clinical significance of GI patency which the PC demonstrated. A retrospective review of the medical records was conducted with 99 consecutive patients with CD who underwent PC and CE at Nagoya University Hospital from January 2010 to May 2015. By using the Cox proportional hazards model, the association between the GI patency evaluated using the PC and the outcome in terms of the rate of patients who needed admission or surgery during the 2-year follow-up was examined. Of all 99 patients who ingested the PC, 84 (84.8%) were diagnosed as not having bowel obstruction, and therefore were eligible for CE (P group). Of the 15 patients in whom bowel obstruction was suspected (NP group), 12 patients underwent either the balloon-assisted endoscopy (n=10) or enteroclysis (n=2), and 11 were confirmed to have small bowel stricture. Non-admission rates of the P and NP groups during the 2-year observation period were 74/84 (88.0%) and 8/15 (53.3%), respectively (P<0.001). Non-operation rates of the P and NP groups during the 2-year observation period were 80/84 (95.2%) and 9/15 (60.0%), respectively (P<0.001). In conclusion, GI patency as diagnosed using the PC was associated with a significantly lower incidence of admission or surgical intervention. PMID- 29581622 TI - Bevacizumab-induced tracheoesophageal fistula in a patient suffering from lung cancer with bulky subcarinal lymph node: a case report. AB - A 66-year-old male with advanced non-small-cell lung cancer (NSCLC) who was previously treated with carboplatin, pemetrexed, and bevacizumab consequently suffered from severe coughing during deglutition. Chest computed tomography (CT) revealed a tracheoesophageal fistula (TEF) between the left main bronchus and esophagus through a subcarinal metastatic lymph node. Given the extreme swelling of the lymph node due to metastatic cancer, it was determined that the walls of the bronchus and esophagus had been injured simultaneously. Delayed and dysfunctional wound healing due to bevacizumab resulted in necrosis of the contact region leading to fistula formation. This case suggests that using bevacizumab for NSCLC in patients with bulky subcarinal lymphadenopathy may increase the risk for TEF. PMID- 29581624 TI - Time for a new resistance against antibiotics. PMID- 29581623 TI - A case of local recurrence of T1 rectal cancer 10 years after transanal excision. AB - We report a case of a patient with T1 rectal cancer, which recurred locally after 10 years from the primary operation. A 78-year-old woman was diagnosed with rectal cancer. Transanal excision (TAE) was performed in December 2006. The pathological findings revealed stage I rectal cancer [tub2>muc, pSM (2,510 um), ly0, v0, pHM0, pVM0]. Because she did not opt for additional treatment, she received follow-up examination. After approximately 10 years from the primary operation, she presented to her physician, complaining of melena, and she was referred to our hospital again in November 2016. She was diagnosed with recurrent rectal cancer. Laparoscopic abdominoperineal resection was performed in December 2016. Pathological findings revealed stage IIIB rectal cancer (tub2>muc, pA, pN1). The reported postoperative local recurrence rate for T1 rectal cancer after TAE is high, but local recurrence after years from the primary operation is rare. In high-risk cases, local recurrence may be observed even after 10 years from the primary operation. Long-term and close postoperative follow-up is important to detect local recurrence early.

AB - The ERBE BiClamp(r) BVSS appears to be a safe and effective method of vaginal hysterectomy in this small single surgeon, single institution study; demonstrating efficient operative times, minimal blood loss and intraoperative morbidity with acceptable surgical outcomes. Its use contributes to the advancement of minimally invasive gynaecology and should be encouraged. PMID- 29581628 TI - The Effect of Interval From Completion of Short-Course Radiotherapy to Surgery on the Post-Operative Morbidity and Mortality of Patients with Rectal Cancer. AB - Aim: Surgery is the mainstay of treatment for invasive rectal cancer. Advances in surgical technique and radiotherapy over the past few decades have resulted in improved local control and survival.1-3 Some concern remains regarding the morbidity associated with performing surgery within a short window following radiotherapy. The current study assessed whether the interval between short course radiotherapy and surgery influences all cause post-operative morbidity and mortality. Methods: All patients who had undergone short-course radiotherapy for rectal cancer within the Belfast Health and Social Care Trust from 2005 to 2014 held on a prospective database were included (n=102). A retrospective review of patients' clinical records was performed and a comparison made of patients who had undergone surgery less than 4 days with those 4 or more days following completion of radiotherapy. Baseline patient and tumour characteristics, post operative complications and readmission rates were compared. Statistical analysis was performed using SPSS (r), Version 22 (SPSS, Inc, Chicago, Illinois, USA). Results: There was no significant difference in mortality or overall post operative complications between groups, however, less serious complications were reduced in patients undergoing surgery less than 4 days following radiotherapy. Perineal wound complications were significantly more common in patients who had undergone surgery 4 or more days following radiotherapy. Conclusion: Our results support the existing data that post-operative complications may be more common with increasing interval to surgery from completion of radiotherapy. Perineal wound morbidity appears significantly more common in patients who undergo surgery 4 or more days following short-course radiotherapy. A larger study to look particularly at perineal wound morbidity and interval from completion of radiotherapy is warranted. PMID- 29581629 TI - Long Term Follow Up of Male Breast Cancer. AB - Introduction: Male breast cancer accounts for less than 1% of breast cancers with published overall and disease free survival being lower than in females. Aims: To determine treatment and long term outcomes for male breast cancer patients in our unit. Methods: A database has been maintained for all breast cancer patients diagnosed in our unit since 1993. Patients were identified using the database and information was collated on patient demographics, tumour pathology, treatment and outcomes using the database and retrospective chart review. Patients were followed to cause of death. Results: From 1994-2009 twenty-four cancers were diagnosed in twenty-two patients. Mean age at diagnosis was 69. Male breast cancer patients were treated using similar principles to female breast cancer. Twenty patients underwent mastectomy, two patients underwent wide local excision. No patients developed local recurrence. One patient died from their breast cancer with systemic metastases. 10-year overall survival was 22%, 10 year disease specific survival was 80%. Other causes of death included medical co-morbidity and secondary cancers. Discussion: Disease free survival in our unit is comparable to other published studies. High age at diagnosis and co-morbidity are the most important factors in determining overall outcome. Treatment pathways for male breast cancer should follow guidelines for female disease in order to optimise outcomes. Future research at national or international level is necessary to ensure the most effective treatments are implemented for male breast cancer patients. PMID- 29581630 TI - Minimally Invasive management of delayed recognition iatrogenic ureteric injury. AB - Introduction: Iatrogenic ureteric injuries are a rare but serious complication of abdomino-pelvic surgery which can be associated with significant morbidity. 65 80% of ureteric trauma is only identified in the postoperative period. Current guidelines recommend stent insertion or urinary diversion via percutaneous nephrostomy. Good quality evidence on success and outcomes remains scant and the optimum treatment pathway unknown. Methods: A retrospective review of all delayed presentation ureteric injuries treated in our unit between 2005 and 2013 was performed. Clinical, treatment and outcome data were collected in a custom proforma. Results: 19 patients with 21 injured ureters met inclusion criteria. 16/19 (84.2%) injuries were sustained during gynaecological procedures with 10 (52.6%) of these during total abdominal hysterectomy. Suspected mechanisms from diagnostic studies was defined as partial transection in 9/21 (42.9%), complete transection in 3/21 (14.3%) and perforation in 1/21 (4.8%).Median time from injury to presentation was 16 days (IQR 7-25). 11/21 (52.4%) had successful stenting with a median time to stent placement of 25 days (IQR 18.5-42). Those with failed stenting had a median time to attempted stenting of 65 days (IQR 10 91.3). Those with successful stenting 3/11 (27.3%) had resolution requiring no further intervention. 6/11 (54.5%) required open reconstruction, with the remaining two patients unfit for reconstruction and managed with long term stents. With successful stenting median time to definitive surgery was 413 days (IQR 156-476). Conclusion: Success rates for stenting are similar to those reported in the literature (55% vs. 44-59%), but resolution rates are significantly lower (15% vs. 44-80%). Data for an endourological approach as a possible long-term solution is limited by heterogeneity, and a further well conducted multicentre prospective study is required.

AB - Background: Nonsense mutations in the dystrophin gene usually result in a severe Duchenne muscular dystrophy phenotype. Findings: We describe a 7-year-old boy with a rare pathogenic mutation in exon 29 c.3940C>T p.(Arg1314Ter) resulting in exon skipping, in turn rescuing the phenotype from a severe Duchenne type to a milder Becker muscular dystrophy type. No adults have been described with this mutation to date. Conclusions: Exon skipping of exon 29 results in a higher level of functional dystrophin. Some cases of muscular dystrophy may still require muscle biopsy to determine optimal management and pharmaceutical treatment options.

PMID- 29581634 TI - Adaptive Learning in Medical Education: The Final Piece of Technology Enhanced Learning? AB - Technology enhanced learning (TEL) is now common practice in the field of medical education. One of the primary examples of its use is that of high fidelity simulation and computerised mannequins. Further examples include online learning modules, electronic portfolios, virtual patient interactions, massive open online courses and the flipped classroom movement. The rise of TEL has occurred primarily due to the ease of internet access enabling the retrieval and sharing of information in an instant. Furthermore, the compact nature of internet ready devices such as smartphones and laptops has meant that access to information can occur anytime and anywhere. From an educational perspective however, the current utilisation of TEL has been hindered by its lack of understanding of learners' needs. This is concerning, particularly as evidence highlights that during medical training, each individual learner has their own learning requirements and often achieves competency at different rates. In view of this, there has been interest in ensuring TEL is more learner aware and that the learning process should be more personalised. Adaptive learning can aim to achieve this by ensuring content is delivered according to the needs of the learner. This commentary highlights the move towards adaptive learning and the benefits of such an intervention. PMID- 29581635 TI - PARAMILITARY SHOOTINGS AND ASSAULTS.

AB - The asymptotic efficiency of a generalized likelihood ratio test proposed by Cox is studied under the large deviations framework for error probabilities developed by Chernoff. In particular, two separate parametric families of hypotheses are considered (Cox, 1961, 1962). The significance level is set such that the maximal type I and type II error probabilities for the generalized likelihood ratio test decay exponentially fast with the same rate. We derive the analytic form of such a rate that is also known as the Chernoff index (Chernoff, 1952), a relative efficiency measure when there is no preference between the null and the alternative hypotheses. We further extend the analysis to approximate error probabilities when the two families are not completely separated. Discussions are provided concerning the implications of the present result on model selection. PMID- 29581649 TI - Small Changes Yield Large Results at NIST's Net-Zero Energy Residential Test Facility. AB - The Net-Zero Energy Residential Test Facility (NZERTF) was designed to be approximately 60 % more energy efficient than homes meeting the 2012 International Energy Conservation Code (IECC) requirements. The thermal envelope minimizes heat loss/gain through the use of advanced framing and enhanced insulation. A continuous air/moisture barrier resulted in an air exchange rate of 0.6 air changes per hour at 50 Pa. The home incorporates a vast array of extensively monitored renewable and energy efficient technologies including an air-to-air heat pump system with a dedicated dehumidification cycle; a ducted heat-recovery ventilation system; a whole house dehumidifier; a photovoltaic system; and a solar domestic hot water system. During its first year of operation the NZERTF produced an energy surplus of 1023 kWh. Based on observations during the first year, changes were made to determine if further improvements in energy performance could be obtained. The changes consisted of installing a thermostat that incorporated control logic to minimize the use of auxiliary heat, using a whole house dehumidifier in lieu of the heat pump's dedicated dehumidification cycle, and reducing the ventilation rate to a value that met but did not exceed code requirements. During the second year of operation the NZERTF produced an energy surplus of 2241 kWh. This paper describes the facility, compares the performance data for the two years, and quantifies the energy impact of the weather conditions and operational changes. PMID- 29581650 TI - An Exploration of the Relationship between Improvements in Energy Efficiency and Life-Cycle Energy and Carbon Emissions using the BIRDS Low-Energy Residential Database. AB - To conduct a more complete analysis of low-energy and net-zero energy buildings that considers both the operating and embodied energy/emissions, members of the building community look to life-cycle assessment (LCA) methods. This paper examines differences in the relative impacts of cost-optimal energy efficiency measure combinations depicting residential buildings up to and beyond net-zero energy consumption on operating and embodied flows using data from the Building Industry Reporting and Design for Sustainability (BIRDS) Low-Energy Residential Database. Results indicate that net-zero performance leads to a large increase in embodied flows (over 40%) that offsets some of the reductions in operational flows, but overall life-cycle flows are still reduced by over 60% relative to the state energy code. Overall, building designs beyond net-zero performance can partially offset embodied flows with negative operational flows by replacing traditional electricity generation with solar production, but would require an additional 8.34 kW (18.54 kW in total) of due south facing solar PV to reach net zero total life-cycle flows. Such a system would meet over 239% of operational consumption of the most energy efficient design considered in this study and over 116% of a state code-compliant building design in its initial year of operation. PMID- 29581651 TI - Motion-plane dependency of the range of dart throw motion and the effects of tendon action due to finger extrinsic muscles during the motion. AB - [Purpose] To clarify the motion-plane dependency of the range of dart throw motion and the effects of tendon action due to long finger flexors and extensors during the motion. [Subjects and Methods] Forty healthy subjects attended the experiment, and the active range of wrist motion in seven motion planes was measured with an originally designed apparatus. [Results] The reliability of the measurement was acceptable. The range of dart throw motion depended on the motion planes, with a maximum at around the motion plane of 45 degrees from the sagittal plane (45 degrees of pronation). The tendon action of long finger muscles was shown in dart throw motion except in 45 degrees of pronation. [Conclusion] Motion-plane dependency of the range of dart throw motion exists in healthy subjects. The absence of tendon action due to finger extrinsic muscles in dart throw motion at 45 degrees might be one of the causes of the advantage of dart throw motion. PMID- 29581652 TI - Effects of extracorporeal shock wave therapy on upper extremity muscle tone in chronic stroke patients. AB - [Purpose] The purpose of this study was to examine the effects of extracorporeal shock wave therapy (ESWT) on upper extremity muscle tone in chronic stroke patients. [Subjects and Methods] For this study, 30 stroke patients participated in this study and they were divided into ESWT group and sham-ESWT group, each group consisted of 15 patients. ESWT and sham-ESWT was performed by the patients for two times a week, for eight weeks. MyotonPRO was used to measure muscle tone. [Results] According to the results of the comparisons between the groups, after intervention, upper extremity muscle tone were significantly higher in the ESWT group than in the sham-ESWT group. [Conclusion] This study showed that ESWT is effective for improving decrease of muscle tone in chronic stroke patients. PMID- 29581653 TI - Effects of mechanical-bed massage on exercise-induced back fatigue in athletes. AB - [Purpose] The study aimed to preliminarily investigate the effects of mechanical bed massage on exercise-induced back fatigue in athletes. [Subjects and Methods] Twelve male college athletes, randomly allocated to experimental or control groups, were instructed to perform reverse sit-up for 8 sessions until they became fatigued. The experimental group received a 20-min mechanical-bed massage session, while the control group rested on a bed for the same period of time. Visual Analogue Scale (VAS) on perceived back muscle fatigue, back muscle endurance, and Heart Rate Variability (HRV) parameters including stress index (SI), HRV index, SDNN, RMSSD, pNN50, LF, HF, and LF/HF were analyzed. [Results] Immediately and 24 hours after the intervention, the VAS significantly differed between the groups. Experimental group's HF was significantly higher immediately after the intervention than control group. Experimental group's LF and LF/HF were significantly lower immediately after the intervention than the control group. [Conclusion] Mechanical bed massage may help athletes overcome the subjective feelings of exercise-induced fatigue, modulate the automatic nervous system activity, especially for balancing sympathetic and parasympathetic activities. Therefore, mechanical bed massage may facilitate recovery from muscle and central fatigue after athlete training or competition.

AB - [Purpose] The purpose of this study was to analyze the effects of pectoralis minor stretching and shoulder strengthening with an elastic band on balance and maximal shoulder muscle strength in young adults with rounded shoulder posture. [Subjects and Methods] Nineteen subjects with rounded shoulder posture were randomly divided into 2 groups: a shoulder stabilization exercise group and a stretching exercise group. The groups performed each exercise for 40 minutes, 3 times a week, for 4 weeks. Static balance (eyes open and closed), dynamic balance (the limits of stability in 4 directions) and shoulder muscle strength in 5 directions were measure before and after the exercises. [Results] The stretching exercise demonstrated a significant difference between the pre- and post-exercise in the static balance with eyes closed and extension and horizontal abduction strength while the stabilization exercise demonstrated significant difference in the left and right directions between the pre- and post-exercise of the dynamic balance and flexion strength. The stabilization exercise demonstrated significant differences shown in the flexion between the pre- and post-test. [Conclusion] The shoulder stabilization and stretching exercises improved the static balance, dynamic balance, and muscle strength. PMID- 29581655 TI - Effect of squatting velocity on hip muscle latency in women with patellofemoral pain syndrome. AB - [Purpose] Neuromuscular activity has been evaluated in patellofemoral pain syndrome but movement velocity has not been considered. The aim was to determine differences in onset latency of hip and knee muscles between individuals with and without patellofemoral pain syndrome during a single leg squat, and whether any differences are dependent on movement velocity. [Subjects and Methods] Twenty four females with patellofemoral pain syndrome and 24 healthy females participated. Onset latency of gluteus maximus, anterior and posterior gluteus medius, rectus femoris, vastus medialis, vastus lateralis and biceps femoris during a single leg squat at high and low velocity were evaluated. [Results] There was an interaction between velocity and diagnosis for posterior gluteus medius. Healthy subjects showed a later posterior gluteus medius onset latency at low velocity than high velocity; and also later than patellofemoral pain syndrome subjects at low velocity and high velocity. [Conclusion] Patellofemoral pain syndrome subjects presented an altered latency of posterior gluteus medius during a single leg squat and did not generate adaptations to velocity variation, while healthy subjects presented an earlier onset latency in response to velocity increase. PMID- 29581656 TI - Limb-dominance and gender differences in the ground reaction force during single leg lateral jump-landings. AB - [Purpose] The purpose of this study was to examine limb-dominance and gender differences in the magnitude of the ground reaction force during single-leg lateral jump-landings. We hypothesized that the peak ground reaction force would be larger in the non-dominant leg compared to that in the dominant leg and would be larger in females compared to that in men. [Subjects and Methods] Fifteen females and 15 males performed jump-landings sideways from a height of 20 cm, with a lateral distance of 60 cm. Vertical and medial ground reaction forces were measured, and the elapsed time from the initial contact to the peak ground reaction force was determined. The loading rate was calculated as the peak ground reaction force divided by the elapsed time from the initial contact to the peak ground reaction force. [Results] The vertical and medial peak ground reaction forces during single-leg lateral jump-landings were larger in females compared to that in males. In addition, the medial peak ground reaction force was larger for the non-dominant leg compared to that for the dominant leg. [Conclusion] The results suggest that in rehabilitation and conditioning settings, evaluations and instructions regarding attenuation are especially important for females and the non-dominant leg. PMID- 29581658 TI - Effect of interferential current therapy on forward head posture. AB - [Purpose] The purpose of this study was to examine the effects of interferential current therapy on the shoulder muscles of subjects with forward head posture. [Subjects and Methods] Thirty volunteers (15 forward head posture, 15 control) participated in this study. Interferential current therapy treatment was conducted for 10 min, three times per week, for 3 weeks on both the upper trapezius and levator scapulae. Subjects were measured anterior both acromion distance and posterior both acromial distance using a ruler, and the forward head posture angle using an electronic application. [Results] Both groups showed significant increases in anterior acromial distance, and decreases in posterior acromial distance and forward head posture angle. [Conclusion] Subjects were concluded that electrical therapy could improve structural alignment; therefore, the implementation of interferential current therapy is expected to be effective for the treatment of forward head posture. PMID- 29581657 TI - Effects of anterior weight-shifting methods on sitting balance in wheelchair dependent patients with spinal cord injury. AB - [Purpose] This study aimed to compare changes in the center of pressure between healthy subjects and patients with spinal cord injury and to provide basic information to these patients for improving their sitting balance. [Subjects and Methods] A total of 12 healthy subjects without histories of neurological or psychiatric disorders and 12 patients with spinal cord injuries were recruited. In all subjects, a change in the center of pressure during the performance of the modified functional reach test was measured using a Force Sensing Array system while the subjects were seated in a wheelchair. In the spinal cord injury group, the change in the center of pressure was highest when subjects reached forward while holding a gym ball. [Results] In the spinal cord injury group, the change in the center of pressure was highest when subjects reached forward while holding a gym ball. A significant correlation between forward reaching of the upper limbs with shoulders at 90 degrees flexion and a change in the center of pressure was found. [Conclusion] Our findings suggest that the combination of functional reaching and the change in the center of pressure assessment is novel enough to be attempted to achieve sitting balance control in patients with spinal cord injury. The findings can provide clinical interventions that contribute to the improvement in the balance ability of wheelchair-dependent individuals. PMID- 29581659 TI - Effects of stabilization exercise using flexi-bar on functional disability and transverse abdominis thickness in patients with chronic low back pain. AB - [Purpose] The purpose of this study is to examine the effects of lumbar stabilization exercises using flexi-bar (FB) on pain, functional disability, transverse abdominis muscle (TrA) activation capacity and thickness in patients with chronic low back pain (CLBP). [Subjects and Methods] Twenty-seven patients were randomly assigned to an experimental (14 patients performing stabilization exercises with flexi-bar (FB)) or control (13 patients performing stabilization exercises) group. The patients in both groups then underwent stabilization exercises with or without FB 30 min/day, 3 times a week, for 6 weeks. The main outcome measures were perceived disability based on the pain, Oswestry disability index (ODI), TrA activation capacity and thickness. [Results] Both groups showed improved ODI, VAS, and TrA activation capacity performed for 6 weeks in patients with CLBP, but all outcomes, except for TrA thickness, showed greater improvements in patients following stabilization exercises with FB than following stabilization exercises. [Conclusion] Based on the above results, lumbar stabilization exercises with FB could restoring pain, functional disability and improving TrA activation capacity in CLBP patients. PMID- 29581660 TI - Postural stability for taekwondo athletes with repetitive ankle sprains during a single-leg stance. AB - [Purpose] The purpose of this study is to investigate postural stability in such group of taekwondo athletes by measuring the center-of-pressure variables in both the injured limb and uninjured limb during a single-leg stance with eyes closed. [Subjects and Methods] The study includes eleven taekwondo athletes with repetitive ankle sprains (RASs) and eleven healthy taekwondo athletes (the controls) at the college level participating in taekwondo training sessions. For the controls, the "injured" limb was taken to be the left limb. [Results] The postural stability measured in both the anteroposterior and mediolateral directions using center-of-pressure variables was lower in the uninjured limb of the RAS group than in the control group during a single-leg stance with eyes closed. However, for the injured limb, there were no significant differences between the two groups. Furthermore, compared to the RAS group, the control group had higher stability in the injured limb than in the uninjured limb. [Conclusion] Individuals with RASs should ensure improvements in their proprioceptive and neuromuscular functions, as well as muscle strength, through an adequate period of rehabilitation to reduce the risk of re-injury. PMID- 29581661 TI - Effects of thoracic posture correction exercises on scapular position. AB - [Purpose] The purpose of this study was to investigate the effects of thoracic extension exercise on scapular alignment and thoracic kyphosis angle. [Subjects and Methods] Ten subjects with a kyphosis angle >=40 degrees and aged between 20 and 26 years participated in this study. This study investigated the scapular forward distance and thoracic kyphosis angle before and after the thoracic extension exercise. [Results] The kyphosis angle after exercise was significantly decreased compared with that before exercise. Scapular forward distance after exercise significantly decreased compared to that before exercise. [Conclusion] The results of the present study suggest that correction of thoracic kyphosis should be included among exercises designed to achieve normal scapular alignment. PMID- 29581662 TI - Relationship between advanced glycation end-product accumulation in the skin and pulmonary function. AB - . [Purpose] This study aimed to evaluate the relationship between advanced glycation end-product accumulation and pulmonary function in a general population with normal spirometry results. [Subjects and Methods] A total of 201 subjects (mean age, 56 +/- 11 years; males, 58%) enrolled in this study. Subjects were classified into two groups (younger group [<65 years old] and elderly group [>=65 years old]). Skin autofluorescence was assessed as an estimate of advanced glycation end-product. Forced vital capacity and forced expiratory volume in one second were measured using a spirometer, and the forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC) was calculated. [Results] Skin autofluorescence was not an independent factor associated with FEV1/FVC in the younger group, but both skin autofluorescence and pack-years of smoking were significant independent factors associated with FEV1/FVC in the elderly group. [Conclusion] Advanced glycation end-product accumulation, assessed by skin autofluorescence, is an independent factor negatively associated with FEV1/FVC in elderly people with normal spirometry results. PMID- 29581663 TI - The effect of gait speed and gait phase to the allocation of attention during dual task gait. AB - [Purpose] The purpose of this study was to determine the change of allocation of attention caused by a difference in gait phase and gait speed. We also determined the relationship between attentional demand and gait automaticity change caused by the gait speed alteration. [Subjects and Methods] Ten male participated. Participants were instructed to perform the probe reaction time (RT) task during treadmill walking in four different gait speed conditions (60%, 80%, 100%, and 120% of preferred speed). Walking ratio in each gait speed conditions were calculated, and RTs and walking ratios were compared in each gait speed condition and in the single-support and double-support gait phase. [Results] RTs were significantly delayed with decline of gait speed. Walking ratio was significantly decreased in proportion of decrement of gait speed. There was no difference of gait phase between single-support and double-support phase. [Conclusion] This study showed that relationship between attentional load and deficit of gait automaticity. While gait phase didn't influence attentional demand, and this result showed the characteristics of treadmill gait. PMID- 29581664 TI - Effects of inspiratory muscle training on pulmonary functions and muscle strength in sedentary hemodialysis patients. AB - [Purpose] This study was conducted to evaluate the effect of Inspiratory Muscle Trainer (IMT) on respiratory muscle strength and pulmonary functions. [Subjects and Methods] Fifteen sedentary unemployed patients were recruited from both genders who received regular hemodialysis sessions from at least three months. Those patients received Threshold IMT program for 12 weeks. Pulmonary functions and respiratory muscle strength in form of (PImax) and (PEmax) were measured by electronic spirometry and digital pressure vacuum meter respectively. Additionally oxygen saturation was measured by Finger pulse oximeter. All measurements were performed before and at the end of the treatment program after 12 weeks. [Results] The results of this study revealed significant improvement in FVC%, FEV1%, PEF%, PImax and PEmax after three months of treatment by using inspiratory muscle trainer while no significant difference was recorded regarding to FEV1/FVC% ratio and SpO2. [Conclusion] Inspiratory muscle trainer is an effective therapeutic technique to improve respiratory muscle strength and pulmonary functions in patients undergoing hemodialysis. PMID- 29581665 TI - Effect of physical activity on cognition and daily living activities of the elderly with mild dementia. AB - [Purpose] The purpose of this study was to examine the effects of a physical activity program on cognitive function and ADLs in elderly people with mild dementia. [Subjects and Methods] Both groups (n=60) participated in a cognition program three times a week for 30 minutes each time over an eight-week period. In addition, the experimental group (n=30) underwent a physical activity program for 30 minutes three times a week over an eight-week period. The LOTCA-G and the FIM were recorded in both groups before and after the experiment to evaluate changes in their cognition and ADLs. [Results] The experimental group showed significant results in 18 subtests and total LOTCA-G, while the control group exhibited significant results in 8 subtests and total LOTCA-G. The comparison results between groups before and after the intervention are as follows. The experimental group showed significant results in 15 subtests and FIM total, while the control group exhibited significant results in 7 subtests and FIM total. The comparison results between groups before and after the intervention are as follows: significant results were revealed in 10 subtests and FIM total. [Conclusion] The physical activity program improves cognitive function and ADLs in patients with mild dementia. PMID- 29581666 TI - Lumbar lordosis angle and trunk and lower-limb electromyographic activity comparison in hip neutral position and external rotation during back squats. AB - [Purpose] To compare the lumbar lordosis angle and electromyographic activities of the trunk and lower-limb muscles in the hip neutral position and external rotation during back squats. [Subjects and Methods] Ten healthy males without severe low back pain or lower-limb injury participated in this study. The lumbar lordosis angle and electromyographic activities were measured using three dimensional motion-capture systems and surface electrodes during four back squats: parallel back squats in the hip neutral position and external rotation and full back squats in the hip neutral position and external rotation. A paired t-test was used to compare parallel and full back squats measurements in the hip neutral position and external rotation, respectively. [Results] During parallel back squats, the average lumbar lordosis angle was significantly larger in hip external rotation than in the hip neutral position. During full back squats, lumbar erector spinae and multifidus activities were significantly lower in hip external rotation than in the hip neutral position, whereas gluteus maximus activity was significantly higher in hip external rotation than in the hip neutral position. [Conclusion] The back squat in hip external rotation induced improvement of lumbar kyphosis, an increasing of the gluteus maximus activity and a decrease of both lumbar erector spinae and multifidus activities. PMID- 29581667 TI - Total assessment-reassessment & evaluation using bioKinesiologic (TAREK) approach: case presentation for theoretical formulation. AB - [Purpose] To introduce a new systematic physical therapy evaluation aiming to facilitate the process of examining complicated musculoskeletal cases. [Subject and Methods] The patient was a 20 years old male college student who had major motor vehicle accident one year ago. The patient was poorly responding to physical therapy and he felt that his case was worsening. The complexity of the case dictated a new evaluation with a different approach to resolve the barriers hindering the patient from showing functional improvements. [Results] The new evaluation approach explained many undetermined and stubborn symptoms experienced by the patient. The expert confirmed that the traditional evaluations methods utilized were insufficient to address patient's complaints. [Conclusion] Total Assessment-Reassessment & Evaluation using bioKinesiologic (TAREK) approach is comprehensive evaluation strategy using systematic pathway that guides clinicians to pinpoint the contribution of pathoanatomical structures in producing pathomechanical mobility and poor functional outcomes. PMID- 29581668 TI - Effects of task-specific paretic ankle plantar flexor training on walking in a stroke patient: a single-case study. AB - [Purpose] The purpose of this study was to examine the effects of task-specific plantar flexor training on walking ability indices in a patient with a paretic ankle. [Subject and Methods] The subject was a 65-year-old male patient with right hemiplegia due to a left medullary ventral infarction. An ABA' single subject design was adopted. The independent variable was a task-specific plantar flexor training exercise, similar to that during walking, targeting the paretic ankle. The dependent variables were the isometric ankle plantar flexor strength, maximum walking speed, step length, and trailing limb angle in the paretic terminal stance phase. The B study phase was divided into B1 and B2 phases. A two standard-deviation-band method was used to evaluate improvement. [Results] Improvements in the paretic plantar flexor strength, maximum walking speed, step length, and trailing limb angle in the B2 phase were observed. The improvements in the maximum walking speed, step length, and trailing limb angle were sustained in the A' study phase. [Conclusion] These results suggest that task-specific plantar flexor training exercise is efficacious in improving the walking ability index of a paretic ankle. PMID- 29581669 TI - Comparision of the effectiveness of ESWT and ultrasound treatments in myofascial pain syndrome: randomized, sham-controlled study. AB - [Purpose] The purpose of this study is to compare effectiveness of extracorporeal shock wave therapy (ESWT), ultrasound (US) and sham ESWT in the treatment of myofascial pain syndrome (MPS). [Subjects and Methods] Sixty MPS patients aged 18 60 years were included in the study. The patients were randomized equally into 3 groups. Group 1 received ESWT for 4 session with 3 day-intervals. Group 2 received 4 sessions of sham ESWT. US was applied to Group 3 for 10 sessions. All patients were recommended an exercise program. The patients were evaluated before post and 6 weeks after treatment. Measurements were made using pressure pain threshold (PPT), pain score (PS) and visual analogue scale (VAS). Patients were evaluated by using SF-36 and HADS (hospital anxiety and depression scale). [Results] A significant posttreatment difference was found in VAS, PPT and SF-36 subparameters in group 1. In group 2, a significant difference was not found in any parameter. In group 3, a significant difference was detected in parameters of VAS and PPT. A significant difference was found between groups 1 and 2 as for subtitles of PPT, VAS, SF-36. [Conclusion] These results suggest that ESWT is as effective as US. ESWT and US are significantly more effective than sham ESWT. PMID- 29581670 TI - Effects of chin tuck exercise using neckline slimmer device on suprahyoid and sternocleidomastoid muscle activation in healthy adults. AB - [Purpose] This study investigated the effect of chin tuck exercise (CTE) using a neckline slimmer device on suprahyoid (SH) and sternocleidomastoid (SCM) muscle activation in healthy adults. [Subjects and Methods] We measured activation of the SH and SCM muscles using surface electromyography in 20 healthy adults during head lift exercise (HLE) and CTE using a neckline slimmer device. The order of exercises was randomized and the mean and peak values of each muscle's activation were assessed. [Results] During the CTE using a neckline slimmer device, SH activation was significantly greater and SCM activation was significantly lower than during the HLE. [Conclusion] This study suggest that chin-tuck exercise using a neckline slimmer device may be more helpful than HLE for swallowing training. PMID- 29581671 TI - Effects of lumbar lordosis assistive support on craniovertebral angle and mechanical properties of the upper trapezius muscle in subjects with forward head posture. AB - [Purpose] The aim of this study was to investigate the effect of lumbar lordosis assistive support (LLAS) on craniovertebral angle (CVA) and mechanical properties of the upper trapezius (UT) muscle in subjects with forward head posture (FHP). [Subjects and Methods] This study recruited 20 subjects with FHP. CVA and muscle tone, viscoelasticity, and stiffness of the UT were measured using Myoton in all subjects in a sitting position with LLAS and in a neutral sitting position. The order of measurements was randomized and the mean values were calculated twice. [Results] The sitting position with LLAS showed a significantly greater improvement than the neutral sitting position with regard to CVA and muscle tone, viscoelasticity, and stiffness of the UT. [Conclusion] We suggest that the sitting position using LLAS induces the maintenance of normal neck posture and a reduction in the muscle tone of the UT in the subjects with FHP. PMID- 29581672 TI - Foot pressure analysis of gait pattern in older Japanese females requiring different personal care support levels. AB - [Purpose] This study evaluated gait parameters and foot pressure in two regions of the feet among older females with different personal care support needs to analyze factors that contribute to higher support requirements. [Subjects and Methods] Thirty-two older females were divided into support-need and care-need level groups. Gait parameters (speed, cadence, step length, step width, gait angle, toe angle, double support phase, swing phase, and stance phase) and foot pressure during a 5-m walk were measured and analyzed in the two groups. [Results] The percentage of the double support phase on both feet and the right stance phase were significantly higher in the care-need level group, while that of the right swing phase was significantly lower than that of the support-need level group. Additionally, the phase showing peak pressure on the left rear foot was significantly delayed and the left forefoot pressure in the terminal stance was significantly lower in the care-need level group than in the support-need level group. [Conclusion] These findings show that the temporal duration parameters and foot pressure on a particular side were significantly different between the two groups and suggest that these differences were associated with a higher care level. PMID- 29581673 TI - Changes in exercise tolerance and quality of life are unrelated in lung cancer survivors who undergo video-assisted thoracic surgery. AB - [Purpose] The associations between changes in respiratory function, exercise tolerance, and quality of life (QOL) in patients with lung cancer who undergo lobectomy using video-assisted thoracoscopic surgery (VATS) are unclear. This study aimed to investigate the relationships between exercise tolerance and QOL in patients who underwent VATS. [Subjects and Methods] Thirty-six patients with lung cancer were followed for 3 months after VATS. Patients were evaluated before and 1, 4, and 12 weeks after surgery. Respiratory function, grip strength, and knee extension strength, as well as the results of timed up and go, 6-minute walk, and cardiopulmonary exercise tests, were evaluated using the 36-item short form health survey. Longitudinal changes in physical performance and QOL were analyzed, as was the relationship between the change in physical function and QOL. [Results] The physical and social aspects of QOL significantly decreased at week 4 post-surgery, but recovered to pre-surgical levels by week 12. In contrast, physical (non-respiratory) function recovered to pre-surgical levels by week 4. There was no correlation between the percentages of change in QOL and those related to physical function. [Conclusion] Our preliminary study highlights the fact that early recovery of physical function is possible after VATS, but does not necessarily correlate with early QOL recovery. It is therefore necessary to perform perioperative interventions to promptly restore QOL after surgery. PMID- 29581674 TI - Novel method for evaluation of hindfoot alignment in weight-bearing position using laser beam. AB - [Purpose] It is clinically important to accurately evaluate the alignment of hindfoot alignment from the body surface in weight-bearing position. In general, measurement is carried out using a goniometer, but the measurement with goniometer requires experience, and the reliability in this measurement is also in question. Therefore, it is necessary to establish a clinical measurement method to replace the goniometer. As a solution, we devised a hindfoot alignment measurement method with laser beam (HAML), which measures hindfoot alignment along the body surface using a laser beam. This study aimed to study the correlation between the measurement result along the body surface with laser or goniometer and that of radiography with regard to hindfoot alignment. [Subjects and Methods] Subjects included 23 individuals with knee osteoarthritis. Their hindfoot alignment using radiography and goniometry were measured. The correlation between the measurement result along the body surface with or without laser and radiography was investigated. [Results] The correlation between HAML and radiography was better than that between HAML and goniometry. [Conclusion] The correlation between radiography and HAML for measuring hindfoot alignment was good. This finding implies that HAML can be used as a screening test or epidemiological survey in regional medicine. PMID- 29581675 TI - The effects of pain scrambler therapy on the pain and quality of life of degenerative gonarthritis patients. AB - [Purpose] The purpose of this study was to identify the effects of pain scrambler therapy on the pain and quality of life of degenerative gonarthritis patients. [Subject and Methods] This study is a single case study. Pain scrambler therapy was applied for 40 minutes per session once a day for 15 days to a 62-year-old female patient diagnosed with degenerative gonarthritis. Pain was measured using the Visual Analogue Scale and quality of life was measured using the short form 36 item after therapy. [Results] Decrease in pain and improved quality of life were evident after pain scrambler therapy. [Conclusion] Pain scrambler therapy had a potential to decrease pain and improve the quality of life in degenerative gonarthritis patients. PMID- 29581676 TI - Choosing Wisely in Surgery-a Perspective from the UK. PMID- 29581677 TI - Laparoscopic-Assisted Transhiatal Esophagectomy (LATE) for Carcinoma of the Esophagus. AB - Total laparoscopic approach for the management of carcinoma of the esophagus has not gained much popularity due to its complexity. The aim of this study was to evaluate safety, feasibility, and outcome of laparoscopic-assisted transhiatal esophagectomy (LATE) for patients with carcinoma of the esophagus. This retrospective study involves a total of 26 patients with carcinoma of the esophagus who were considered for LATE by a single surgical team from January 2010 to September 2014. The median (range) age was 55 years (35-72), and male to female ratio was 20:6. The median (range) operative time, blood loss, and hospital stay were 300 min (180-660), 300 ml (100-500), and 11.5 days (8-25), respectively. Pulmonary complications and cervical anastomotic leak (including one patient with conduit necrosis) occurred in eight (30.7 %) and three (11.5 %) patients, respectively. AJCC stage (7th ed.) was IIA in 12 (46.15 %), IIB in 10 (38.46 %), IIIA in 3 (11.53 %), and IIIB in 1 (3.84 %) patient. Surgical resection margin was negative in all but one patient (3.8 %). The median (range) number of lymph nodes (LN) retrieved was 13 (8-28). During a median follow-up 19 months (8-39), five patients (19.23 %) developed recurrence and three (11.5 %) of them died. LATE is a safe and feasible for the management of selected patients with carcinoma of the lower thoracic esophagus. PMID- 29581678 TI - Ten-Year Experience of Managing Giant Duodenal Ulcer Perforations with Triple Tube Ostomy at Tertiary Hospital of North India. AB - Duodenal ulcer perforations have been known since 1600 AD. It is a common surgical emergency and every surgeon will encounter it. The perforation size of >2 cm has been used as the criteria for defining Giant duodenal ulcers. The management of giant duodenal perforations in hemodynamically unstable patient with comorbid condition is taxing because of high incidence of the postoperative leak and mortality. We have used the simple technique of Triple Tube Ostomy after the primary closure of the defect with encouraging results. It is a retrospective study done at the J. N medical college AMU Aligarh from May 2005 to May 2015. Hemodynamically unstable patients who have presented to the emergency with preoperative diagnoses of giant duodenal ulcer perforation and had undergone triple tube ostomy with primary repair of the perforation were included in the study. There were 34 patients of giant duodenal perforation who presented in shock. All of them underwent triple-tube-ostomy after primary repair of the duodenum. Thirty-two patients recovered with two mortalities (5.8 %). Several definite surgical techniques have been described for the management of giant duodenal ulcer perforation but they are complex, have very high morbidity and mortality rate and require an expert surgeon. A close retrospective scrutiny of the patients suggests that simple triple-tube-ostomy technique which is based on the principle of damage control surgery has good postoperative results Therefore, we recommend it as the procedure of choice in these patients. PMID- 29581679 TI - Balloon-Inflated Catheters for Enteral Feeding: a Word of Caution. AB - Catheters with inflatable balloons such as a Foley catheter may be used for feeding gastrostomy/jejunostomy. The incorrect or improper use of these catheters can have serious consequences. We report 13 cases of feeding jejunostomy with balloon-inflated catheter's malfunction, some referred to our centre and others operated here over a period of 8 years. The most dramatic consequence of such improper use led to rupture of the small intestine due to inadvertent over inflation (over 100 ml) of the balloon of the catheter during a contrast study. The patient required a laparotomy with resection and anastomosis of the bowel. Three other patients had similar over-inflation of the balloon leading to severe pain and discomfort. In all three patients, timely deflation of the balloon was sufficient to relieve the symptoms. One patient had intussusception with the inflated balloon acting as a lead point. The patient underwent resection of the small bowel with end jejunostomy and distal mucous fistula. All other patients presented with abdominal pain and distension and intestinal obstruction and were managed non-operatively with deflation of balloon either by aspiration, cutting the balloon port or ultrasound-guided puncture of balloon. Healthcare personnel dealing with patients with indwelling catheters must be educated to suspect, detect and manage such problems. The best measure for such unusual complications of otherwise safe devices would be prevention by training and generation of awareness. PMID- 29581680 TI - Sexuality in Surgically Treated Carcinoma Penis Patients and Their Partners. AB - Most common treatment offered to carcinoma penis patients is surgery. This results in not only mutilation of the genitals but also affects their sexuality. The treating physician fails to address the issue due to the paucity of the data in this regard. Hence, we decided to evaluate sexuality in these patients after surgical treatment for penile cancer. Most of the times, their partners also face problems of sex and sexuality, regarding which there is no literature. Hence, we decided to include their partners also in the study. We retrieved records of the patients who underwent surgical treatment for carcinoma penis at our institute. After obtaining ethical committee approval, they were invited along with their partners for personal interview. After obtaining written informed consent from each of them, they were administered sexual functioning questionnaire (SFQ). Sexuality was evaluated based on the scores obtained. Performance anxiety was reported by majority of these patients. Their sexual interest, arousal and desire remained almost intact with reduction in satisfaction more so in total penectomised patients. Though the partners had accepted the global reduction in sexuality as their fate, their interpersonal relationship remained little disturbed. The study reveals that sexuality is more than the sexual intercourse alone. Proper pre-operative counselling of these patients and their partners by the treating urologist helps better post-treatment adjustment with regards to sexuality in these patients as well as their partners. PMID- 29581681 TI - Robot-Assisted Mckeown Esophagectomy is Feasible After Neoadjuvant Chemoradiation. Our Initial Experience. AB - Neoadjuvant chemoradiation has become the standard of care for esophageal cancer, especially for middle third esophageal lesions and those with squamous histology. Although more and more thoracic surgeons and surgical oncologists have now shifted to video-assisted and robot-assisted thoracoscopic esophagectomy; there is still limited experience for the use of minimal-assisted approaches in patients undergoing surgery after neoadjuvant chemoradiation. Most surgeons have concerns of feasibility, safety, and oncological outcomes as well as issues related to difficult learning curve in adopting robotic esophagectomy in patients after chemoradiation. We present our initial experience of Robot-Assisted Mckeown Esophagectomy in 27 patients after neoadjuvant chemoradiation, from May 2013 to October 2014. All patients underwent neoadjuvant chemoradiation to a dose of 50.4 Gy/25Fr with concurrent weekly cisplatin, followed by reassessment with clinical examination and repeat FDG PET/CT 6 weeks after completion of chemoradiation. Patients with progressive disease underwent palliative chemotherapy while patients with either partial or significant response to chemoradiation underwent Robot-Assisted Mckeown Esophagectomy with esophageal replacement by gastric conduit and esophagogastric anastomosis in the left neck. Out of 27 patients, 92.5 % patients had stage cT3/T4 tumours and node-positive disease in 48.1 % on imaging. Most patients were middle thoracic esophageal cancers (23/27), with squamous histology in all except for one. All patients received neoadjuvant chemoradiation and subsequently underwent Robot Assisted Mckeown Esophagectomy. The average time for robot docking, thoracic mobilization and total surgical procedure was 13.2, 108.4 and 342.7 min, respectively. The procedure was well tolerated by all patients with only one case of peri-operative mortality. Average ICU stay was 6.35 days (range 3-9 days). R0 resection rate of 96.3 % and average lymph node yield of 18 could be achieved. Pathological node negativity rate (pN0) and complete response (pCR) were 66.6 and 44.4 %, respectively. In the initial cases, four patients had to be converted to open due technical reasons or intraoperative complications. The present study, with shorter operative times, similar ICU stay, overall low morbidity, and mortality and optimal oncological outcomes suggest that robot-assisted thoracic mobilization of esophagus in patients with prior chemoradiation is feasible and safe with acceptable oncological outcomes. It has a shorter learning curve and hence allows for a transthoracic minimally invasive transthoracic esophagectomy to more and more patients, otherwise unfit for conventional approach. PMID- 29581682 TI - Comparing Hemodynamic Symptoms and the Level of Abdominal Pain in High- Versus Low-Pressure Carbon Dioxide in Patients Undergoing Laparoscopic Cholecystectomy. AB - The laparoscopic cholecystectomy (LC) is the gold standard to treat gallstone. To view the surgical site in this type of operations better, carbon dioxide is used with a certain pressure. The current study aimed to compare the hemodynamic symptoms and the level of abdominal pain due to using high- and low-pressure carbon dioxide in patients undergoing LC. The current double-blind randomized clinical trial was conducted on 60 patients with the age range of 20-70 years old undergoing LC. The first and second groups experienced PaCO2 of 7-10 and 12-14 mmHg, respectively. The hemodynamic symptoms, abdominal pain, shoulder-tip pain, nausea and vomiting after the surgery, and the mean of liver function tests were evaluated. Data were analyzed using T test, Chi-square test, and repeated measures ANOVA by SPSS 16. Information of 60 patients in two groups was analyzed. There was a significant difference between the groups regarding the mean of systolic blood pressure (P < 0.05). The mean of heart rate was significantly higher in the high-pressure group during surgery and 1 h after that (P < 0.05). The frequency of pain in shoulder-tip and abdomen was higher in the high-pressure group. Frequency of nausea and vomiting 12 h after the surgery between two groups was significant (P < 0.05). The mean of alkaline phosphatase was higher in the low-pressure group than the high-pressure group (P < 0.05). Considering the good performance and low side effects of low-pressure laparoscopic cholecystectomy compared to those of high-pressure, this method can be replaced by high-pressure in LC. PMID- 29581683 TI - An Analysis of Presentation, Pattern and Outcome of Chest Trauma Patients at an Urban Level 1 Trauma Center. AB - Chest trauma is an important public health problem accounting for a substantial proportion of all trauma admissions and deaths. It directly account for 20-25 % of deaths due to trauma. Therefore, this study was conducted to analyze the presentation, patterns, and outcome of chest trauma in a level-1 urban trauma center. It was a prospective observational study of all patients presented with chest trauma to an urban level 1-trauma center over a period of 3 years. Demographic profile, mechanism of injury, injury severity scores (ISS), associated injuries, hospital stay, etc. were recorded. Morbidity and mortality rates were analyzed and compared with the published literature. Chest injuries comprised 30.9 % of all trauma admissions and the mechanism was blunt in majority (83.5 %) of the cases. Vehicular crashes (59.7 %) followed by assault were the most common modes of injury. Rib fracture was the most common chest injury seen in 724 of the 1258 patients while abdominal visceral injuries were the commonest associated injuries in polytrauma cases. Majority of the patients were managed non-operatively. Inter costal tube drainage (ICD) was the main stay of treatment in 75 % of the cases, whereas, thoracotomy was required only in 5.56 % of the patients. Overall mortality was 11 % and it was found to be significantly higher following blunt chest trauma. We observed that associated extra thoracic injuries resulted in higher mortality as compared to isolated chest injuries. Thoracic injuries can be readily diagnosed in the emergency department by meticulous and repeated clinical evaluation and majority require simple surgical procedures to prevent immediate mortality and long-term morbidity. PMID- 29581684 TI - Robotic Pancreaticoduodenectomy: Single-Surgeon Initial Experience. AB - Minimally invasive surgery has gained increasing acceptance over the last few years, which has expanded to pancreaticoduodenectomy. Laparoscopic pancreaticoduodenectomy has been determined to be a feasible, safe, and effective procedure in an experienced surgeon's hands, but the adaptations to the clumsy instruments are needed. The improved dexterity of the Da Vinci robotic system provides a good opportunity to perform this challenging procedure in the minimally invasive context. The aim of this study was to share our preliminary experience of totally robotic pancreaticoduodenectomy. From April 2015 to August 2015, four patients were selected to undergo totally robotic pancreaticoduodenectomy in the Department of Pancreatic Surgery, West China Hospital, Sichuan University, China. The demographic characteristics, perioperative details, and pathological results were retrospectively reviewed. One female and two male patients underwent totally robotic pancreaticoduodenectomy, while another male patient underwent robotic total pancreatectomy due to the severe atrophy of pancreatic body and tail. The mean age of the four patients was 56.8 years. The average operation time and intraoperative blood loss were 563 min and 228 mL, respectively. No one needed blood transfusion, conversion to open pancreaticoduodenectomy, or postoperative analgesia. The postoperative courses of these patients were uneventful. The mean postoperative hospital stay was 10 days. No one required to be readmitted, and there was no death within 30 days following the surgery. Final pathologic examinations revealed one malignant pancreatic ductal adenocarcinoma, and three benign lesions. Based on this initial study, robotic pancreaticoduodenectomy is safe and feasible, with acceptable oncological outcomes for highly selected patients in experienced surgeons' hands. However, concerns such as long-term outcomes, cost-effectiveness analysis, and learning curve analysis should be fully demonstrated before the popularization of this challenging procedure. PMID- 29581685 TI - Incidental Findings in Routine Histopathological Examination of Appendectomy Specimens; Retrospective Analysis of 1970 Patients. AB - Diseases and tumors of the appendix vermiformis are very rare, except for acute appendicitis. This study aimed to examine rare findings in the histopathologic examinations of specimens of patients undergoing appendectomy due to the diagnosis of acute appendicitis. The files of 1970 patients undergoing appendectomy due to the diagnosis of acute appendicitis between March 2012 and March 2016 were retrospectively investigated. Rare findings were found in 59 (3 %) patients, and these were evaluated in detail. Patients' age, gender, pathology reports, and postoperation follow-ups were recorded. The rare histopathological findings of 59 patients were examined. Of these, 31 were female (52.5 %) and 28 were male (47.5 %). The average age was 33.1 +/- 18.2 years. The unusual findings were as follows: 16 fibrous obliteration, 11 Enterobius vermicularis, 2 schistosomiasis, 3 appendiceal neuroma, 2 granulomatous appendicitis, 1 Crohn's disease, 3 chronic appendicitis, 1 endometriosis, 2 hyperplastic polyps, 9 mucinous cystadenoma (+mucocele), 8 carcinoid tumors, and 1 lymphoma. All of the malignant tumors were localized in the distal end of the appendix, and all of the patients were treated with appendectomy. Patients with parasitic diseases also underwent anthelmintic treatment, while chemotherapy was administered to the patient with lymphoma. All of the patients diagnosed with malignancy were alive reported no problems at their follow-ups. Although all of the appendectomy samples were normal macroscopically, data from this study suggest that all specimens should be sent for routine investigation. PMID- 29581686 TI - The Charlson Comorbidity Index as an Independent Prognostic Factor in Older Colorectal Cancer Patients. AB - High-age patients have higher rates of comorbidity that are associated with a poor prognosis. It is important to correctly evaluate their preoperative status to avoid mortality. The aim of this study was to clarify whether the Charlson comorbidity index (CCI) was useful for predicting postoperative outcomes. This retrospective study collected data from 250 consecutive patients over 75 years of age. The CCI takes into account 19 comorbid conditions. Inflammation-based scores, including the Glasgow prognostic score (GPS) and the platelet to lymphocyte ratio (PLR), are other preoperative scoring systems. The relationships among these scores and postoperative outcomes were evaluated. The patients were classified according to their vital status (dead, n = 30 or alive, n = 220). Comorbidities, the presence of double cancer, and lymph node metastases were significantly different between the groups (p < 0.01, p = 0.01, and p < 0.01). In regard to the scoring systems, the CCI, GPS, and PLR were significantly different (p = 0.02, p = 0.03, and p = 0.05). Multivariate analysis identified CCI >= 2 (hazard ratio (HR) = 5.24, 95 % confidence interval (CI) = 1.30-12.1, p = 0.01) as a significant determinant of postoperative outcome (p < 0.01). The overall survival tended to be lower in patients with high CCI scores group (p = 0.03). The CCI was useful to predict postoperative outcomes in high-age colorectal cancer patients. PMID- 29581687 TI - Efficacy of the Evaluation of Inflammatory Markers for the Reduction of Negative Appendectomy Rates. AB - Unnecessary appendectomy can cause complications; ways of reducing negative appendectomy rates (NAR) using biochemical and imaging methods are desirable. We retrospectively examined 640 patients who underwent appendectomy for suspected AA. Patients with histologically confirmed appendicitis were designated the positive appendectomy group (n = 565), whereas those with unconfirmed appendicitis were designated the negative appendectomy group (n = 75). The positive appendectomy group was subdivided into the non-perforated (n = 511) and perforated (n = 54) appendectomy groups according to pathology reports. We compared the age, sex, lymphocyte count, neutrophil percentage, pathologic positivity or negativity for appendicitis, C-reactive protein (CRP) level, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) of the patients. When the perforated, non-perforated, and negative appendectomy groups were compared, the highest CRP level, NLR, and PLR were evident in the perforated appendectomy group (p = 0.001), whereas the lowest neutrophil percentage was found in the non-perforated appendectomy group (p = 0.001). Multiple logistic regression analysis identified neutrophil percentage, CRP value, and NLR as independent variables and demonstrated that AA could be diagnosed with 88.9 % accuracy using the cutoff values determined. In patients with suspected AA, particularly in rural areas with limited access to advanced imaging modalities, the evaluation of neutrophil percentage, CRP level, and NLR, in combination with the findings of a physical examination, may aid diagnosis and reduce NAR. PMID- 29581689 TI - Synchronous Squamous Cell Carcinoma of the Anorectum and Proctosigmoid-a Case Report. AB - Primary squamous cell carcinoma of the rectum is extremely rare. Squamous cell carcinoma of the anorectum is a known entity evaluation and treatment protocols have been well defined. The occurrence of squamous cell carcinoma of rectosigmoid in concurrence with squamous cell carcinoma of the anal canal is extremely rare and the first case to be reported in the literature. A 48-year-old male patient presented with difficulty in passing stools. The clinical examination, colonoscopy, and the histopathology revealed synchronous proctosigmoid and the anorectal neoplasm. A case like this will pose a diagnostic challenges; squamous cell carcinoma of the rectum is not defined in the medical literature; synchronous squamous cell carcinoma will pose both diagnostic dilemmas and treatment challenges like whether to conserve the sphincter or not. Because squamous cell carcinoma of the anorectum can be treated by chemoradiotherapy, even this case is initially thought of treating by neoadjuvant chemoradiotherapy followed by low anterior resection followed by adjuvant treatment. Since there was no medical literature to support this treatment, ultimately multidisciplinary tumor board decision was made for abdominoperineal resection. Patient was treated with abdominoperineal resection and adjuvant chemoradiation. The diagnostic dilemmas and the management issues have been discussed. PMID- 29581688 TI - Introducing In Vivo Dissection Modules for Undergraduate Level Trainees: What Is the Actual Benefit and How Could We Make It More Efficient? AB - Essential Skills in the Management of Surgical Cases (ESMSC) is an international wet lab simulation course aimed at undergraduate students. It combines basic science workshops, case-based lectures and ex vivo skills modules, as well as in vivo dissections using a swine model. This study aims to evaluate the effectiveness of high-fidelity In Vivo Simulation-Based Learning for undergraduate level trainees. Also our goal was to compare the skill-based performance of final year students vs. more junior-level ones. Forty undergraduate delegates at clinical rotation level (male = 28, female = 12, mean age = 23.12, 22-24, SD = 0.69) attended this 2-day course in Athens. N = 1 (2.5 %) was year 3, N = 4 (10 %) were year 4, N = 23 (57.5 %) were year 5 and N = 12 (30 %) were year 6. N = 30 (75 %) came from Hellenic universities, N = 8 (20 %) from the UK and N = 2 (5 %) from Germany. N = 20 (50 %) attended the in vivo dissections module first, and then the ex vivo one (type A rotation), whereas N = 20 followed the reverse training sequence with the ex vivo dissection first, followed by the in vivo one (type B rotation). The mean global rating scores for type A rotation were better in both the in vivo by 0.10 (2.40 vs. 2.30) and ex vivo modules by 0.15 (2.85 vs. 2.70), though it did not reach statistical significance (p > 0.05). Furthermore, the mean improvement of performance, in the laparoscopic skills station for the type A rotation, was better compared to type B by 0.351 (2.00 vs. 1.65, p = 0.003). Year 6 students performed better in the laparoscopic station (2.00 vs. 1.75, p = 0.059), whereas years 3, 4 and 5 performed better in the in vivo (2.42 vs. 2.16, p = 0.157) as well as the ex vivo dissections (2.78 vs. 2.75, p = 0.832), though none of those comparisons reached statistical significance. Delegates seemed to appreciate and enjoy the in vivo dissections as reflected in the feedback (8.67/10, min = 6 and max = 10, SD = 1.79). Although medical students seem to appreciate in vivo dissections modules, currently, further evidence is needed to support their recommendation in the undergraduate level. Surgical skills should be part of the undergraduate curriculum to improve final year students' performance in the theatre. PMID- 29581690 TI - Mentoring in Surgery-Mentor, Parshuram, Dronacharya, Krishan. AB - Success in any profession has no well-defined predictors. Knowledge, skills, training, and talent come in plenty but fail at times to achieve the universal goal of success. Some attribute it to luck. Apart from the tangible ingredients of a successful career, the intangibles like luck or something ill-defined is a real challenge. The intangibles seem like a chasm, an abyss, or a phantom obstacle. Presence of a guiding spirit who can handhold you to overcome these is essential for success. The aim of a professional is to learn, earn, and yearn for creativity. Practice of surgery is an ideal career to pursue the learning, earning, and yearning. More than any other profession, the guiding handholding spirit is required in surgical profession, the concept of mentoring. Originating from the Greco-Roman times when kind Odysseus left his son Telemachus under the care of his friend, mentor, it has become a universal defining necessity for a successful career in surgery. Indian history replete with such examples of mentorship, good as in the case of Dronacharya to Kaurvas but bad as denied by an able, competent, aspiring student like Eklavya. In the medical profession, there are very few Indian role models of mentorship. One name that comes to our mind is Dr. Krishan Mahajan. The more said is less revealed about him. "Knife before wife" was his commonly spoken advice to all who sought his mentorship. "Hard work is not easy but it is fair" so said a famous boxer, Larry Holmes. It is more than true for our profession as it is better to prepare and prevent, rather than repair and repent. PMID- 29581691 TI - Transmural Migration of Gossypiboma: a Rare Cause of Acute Abdomen. AB - Gossypiboma is the retained foreign body which is generally a cotton sponge/gauze after surgery. Incidence of gossypiboma is around one in 3000 to 5000 surgeries. This low incidence is mainly attributed to a low case reporting due to an associated medicolegal aspect. We are reporting a case of a 38 years old male, who presented with signs and symptoms of peritonitis. The patient had a history of open cholecystectomy 2 years back. A working diagnosis of perforation peritonitis was made, and the patient underwent exploratory laparotomy. Intraoperatively, a surgical sponge was present inside the ileal lumen causing intestinal obstruction with dense adhesion of bowel loops proximal to the site of obstruction with multiple ileal perforations. Even though the incidence of gossypiboma is very low, it should always be kept in mind as a cause of chronic abdominal pain and abdominal discomfort in a patient with previous abdominal surgery. PMID- 29581692 TI - Rupture of Cystic Artery Pseudoaneurysm: a Rare Complication of Acute Cholecystitis. AB - Pseudoaneurysm (PA) of the cystic artery is rare. Most of the reported cases are iatrogenic and develop secondary to liver biopsy, laparoscopic cholecystectomy, ERCP, and liver transplant. Other reported causes include trauma, malignancy, arteriovenous malformations, and inflammation in the hepatobiliary and pancreatic system. Cystic artery psuedoaneurysm is usually asymptomatic but may also present as vague abdominal pain, intra-abdominal mass, and hemobilia. In the event of rupture, it may present as a catastrophic intra-peritoneal bleeding with hemorrhagic shock. Doppler ultrasound and contrast-enhanced CT scan are useful tools for the diagnosis of this condition. However, selective visceral angiography is confirmatory and offers the opportunity for therapeutic embolization. We report a case which presented with upper right quadrant abdominal pain, vomiting, and hypotension. Abdominal ultrasonography revealed subhepatic hematoma and pericholecystic fluid collection along with acute calculus cholecystitis and sludge in the bile duct. Subsequent contrast-enhanced CT and CT angiography confirmed the presence of ruptured cystic artery psuedoaneurysm with subhepatic hematoma. The patient after resuscitation underwent selective visceral angiography and successful coil embolization of the cystic artery pseudoaneurysm. During the same admission, ERCP and biliary stenting were also performed followed by laparoscopic cholecystectomy. This case reports a rare entity which was successfully treated using a multimodality strategy. PMID- 29581693 TI - Large Solitary Plexiform Neurofibroma of the Penis Without Erectile Dysfunction: a Case Report from Kerala. AB - Case Report: Solitary plexiform neurofibroma of the penis is an extremely rare peripheral nerve lesion with only about 20 cases reported all around the world. Here, we are reporting a case of solitary penile plexiform neurofibroma with sexual dysfunction due to difficulty in penetration. This 47-year-old gentleman presented with a swelling on the dorsal side of the penis. He was aware of the swelling for the last 15 years. The swelling was slow growing and there was no associated loss of sensation or sexual dysfunction. For the last 2 months, he noticed that the tumour is rapidly increasing in size. He was also having difficulty in penetration during sexual intercourse which forced him to seek medical attention. He underwent excision of the swelling from our department. After 18 months of follow-up following excision, there has been no evidence of recurrence of the tumour. Conclusion: Penile plexiform neurofibromas are a rare type of lesions and are usually associated with neurofibromatosis. Solitary penile plexiform neurofibromas are extremely rare. Excision, when done properly, gives good results, without erectile dysfunction. PMID- 29581694 TI - Mayer-Rockitansky-Kuster-Hauser Syndrome Presenting as Irreducible Inguinal Hernia. AB - Inguinal hernia is the most common type of hernia experienced in the surgical OPD due to the muscular anatomy of the region being weak along with the natural weaknesses like deep ring with indirect hernia being more common than direct. Inguinal hernias may have varying unusual sac contents, a case presentation of rudimentary uterus and ovaries as contents of inguinal hernia in an adult female with Mayer-Rokitansky-Kuster-Hauser (MRKH) type II syndrome. This syndrome may be attributed to abnormal development of blastema of cervicothoracic somites and pronephriducts. PMID- 29581695 TI - Extreme Small Bowel Enteroatmospheric Fistula.

PMID- 29581697 TI - Drain Tags: A Reliable Method of Securing Drains in the Neck. AB - Drains are essential in most surgeries. Primary need is elimination of dead space and related consequences but drains per se do have their share of complications, one of them being dislodgment. Complications related to dislodgment can range from inactive drains to damage to critical areas like anastomosis sites. Securing drains using this technique was described by Jayaraj et al. in 1988. Since then, no study was done to determine the efficacy and outcomes of this method. An audit was conducted from 2009 to 2014 at SDM Craniofacial unit to determine the utility of drain fixation. Data was collected of a total of 143 patients from the medical records. This useful technique has the advantage of preventing the drain from displacement and its consequent complications.

PMID- 29581699 TI - Significant Points in Complicated Appendicitis. PMID- 29581700 TI - Red-Enhanced Photon Detection Module Featuring a 32 * 1 Single-Photon Avalanche Diode Array. AB - In this letter, the development and the experimental characterization of a new photon detection module, based on a 32*1 red-enhanced single-photon avalanche diode (RE-SPAD) array, are presented. A custom-developed technology has been exploited to design a detector having large-area pixels (50-um diameter) with optimized performance. With an excess bias voltage Voupsilon = 15 V, a photon detection efficiency as high as 57% at 600 nm (33% at 800 nm) is achieved, along with dark count rate in the kHz range and optical crosstalk probability as low as 0.29%. The remarkable detection efficiency of the RE-SPAD array makes the module particularly suitable for all applications where high detection efficiency in the red/near-infrared range is mandatory. As an example, the performance of the array module is demonstrated to match the demanding requirements of multispot single molecule fluorescence spectroscopy. PMID- 29581701 TI - Thyroid Nodule Management: Thyroid-Stimulating Hormone, Ultrasound, and Cytological Classification System for Predicting Malignancy. AB - Background/objectives: Thyroid nodule (TN) is a common thyroid disorder globally, and the incidence has been increasing in recent decades. The objective of this study was to determine the contribution of thyroid-stimulating hormone (TSH), ultrasound (US), and cytological classification system for predicting malignancy among the surgically excised nodules. Design and methods: A retrospective analysis was performed between January 2012 and December 2014, using data drawn from 1188 patients (15-90 years), who had 1433 TN and fine-needle aspiration in Prince Sultan Military Medical City, Saudi Arabia. After reviewing all the thyroid cytopathological slides and US reports, classification was done based on the Bethesda System for Reporting Thyroid Cytology and the Thyroid Imaging Reporting and Data System (TI-RADS). Results: A total of 1188 patients' medical records were reviewed for this study, among them 311 patients had undergone surgical intervention (253 patients had single nodule and 58 had 2 nodules), with a total of 369 nodules. However, as 54 nodules on the US were either unavailable or unclear, the 315 remaining nodules were analyzed, revealing 30.2% (n = 95) malignancy overall. Patients with TSH values of >4.5 mIU/L (38.2%), TN <1 cm (48.8%), TI-RADS category 5 (75.6%), and Bethesda category VI (88.9%) revealed a higher percentage of malignancy. From the univariate analysis using the chi2 test, significant relationship between the TSH, nodule size, TI-RADS, and the Bethesda category between the malignant and benign nodules emerged. The regression analysis showed that patients with a TSH value of 0.5 to 4.5 mIU/L (odds ratio [OR]: 2.96), TSH >4.5 mIU/L (OR: 6.54) had higher risk for malignancy than those with a TSH value of <=0.4 mIU/L. Thyroid nodules with sizes of 1 to 1.9 cm (OR: 1.12), 2 to 2.9 cm (OR: 0.74), 3-3.9 cm (OR: 1.21), and >=4 cm (OR: 0.52) were found to have no association with the risk of malignancy. Compared with TI-RADS 2 patients, those with categories 4B (OR: 1.35) and 5 (OR: 2.3) were found to be at higher risk of malignancy. Similarly, Bethesda IV (OR: 2.72), V (OR: 8.47), and VI (OR: 20; P < .02) category patients had a higher risk for malignancy than those in Bethesda class I. Among the study population, the papillary thyroid carcinoma was the most common type of thyroid cancer (86, 90.5%) followed by 7.4% (n = 7) of follicular thyroid carcinoma, 1.05% (n = 1) of anaplastic carcinoma, and 1.05% (n = 1) of medullary thyroid carcinoma. Conclusions: A predictive model for risk of malignancy using a combining characteristic of the TSH, US, and cytological classification systems could assist the clinicians in minimizing exposing the patients with TNs to nonessential invasive procedures. PMID- 29581702 TI - Linear-In-Flux-Expressions Methodology: Toward a Robust Mathematical Framework for Quantitative Systems Pharmacology Simulators. AB - Quantitative Systems Pharmacology (QSP) modeling is increasingly used as a quantitative tool for advancing mechanistic hypotheses on the mechanism of action of a drug, and its pharmacological effect in relevant disease phenotypes, to enable linking the right drug to the right patient. Application of QSP models relies on creation of virtual populations for simulating scenarios of interest. Creation of virtual populations requires 2 important steps, namely, identification of a subset of model parameters that can be associated with a phenotype of disease and development of a sampling strategy from identified distributions of these parameters. We improve on existing sampling methodologies by providing a means of representing the structural relationship across model parameters and describing propagation of variability in the model. This gives a robust, systematic method for creating a virtual population. We have developed the Linear-In-Flux-Expressions (LIFE) method to simulate variability in patient pharmacokinetics and pharmacodynamics using relationships between parameters at baseline to create a virtual population. We demonstrate the importance of this methodology on a model of cholesterol metabolism. The LIFE methodology brings us a step closer toward improved QSP simulators through enhanced capture of the observed variability in drug and disease clinical data. PMID- 29581703 TI - Mental Health in School-Aged Children Prenatally Exposed to Alcohol and Other Substances. AB - Prenatal exposure to substances can possibly influence a child's neurodevelopment and may impact on subsequent mental health. We investigated the mental health status of school-aged children referred to a pediatric hospital with a history of prenatal exposure to alcohol or other substances. Mental health was assessed using the Strengths and Difficulties Questionnaire and compared with a reference group. A total of 105 of 128 (82%) eligible children prenatally exposed to substances participated in the study, with 48 children exposed to alcohol and 57 to other substances. Strengths and Difficulties Questionnaire subscale mean scores, total difficulties scores, and total impact scores were statistically significantly higher in the group of exposed children, compared with the reference group. In this hospital-based population of school-aged children prenatally exposed to alcohol or other substances, the exposed group had an increased risk of mental health problems, compared with the reference group. PMID- 29581704 TI - Targeting Histone Demethylase LSD1/KDM1a in Neurodegenerative Diseases. AB - The autophagy-lysosome pathway sustains cellular homeostasis and is a protective mechanism against neurodegenerative diseases. Recent findings highlight the role of the histone demethylases LSD1/LDM1A as a pivotal regulator of autophagy process, by controlling the mTORC1 cascade, in neuroblastoma cells. LSD1 binds to the promoter region of the SESN2 gene, where LSD1-mediated demethylation leads to the accumulation of repressive histone marks that maintain SESN2 expression at low levels. LSD1 depletion results in enhanced SESN2 expression and consequently mTORC1 inhibition, thereby triggering the induction of autophagy. Our study provides important insight into neuroepigenetic mechanisms regulating the autophagic process, offering additional opportunities for the development of novel therapeutic strategies in diseases associated with dysfunctional autophagy lysosomal pathway. PMID- 29581705 TI - Hypoglycemic Coma in a Hemodialysis Patient Receiving Blood Glucose-Lowering Therapy With the Single Agent Teneligliptin. AB - Blood glucose management in patients undergoing dialysis is clinically challenging. In this population, most conventional oral hypoglycemic agents are contraindicated, especially from the perspective of pharmacokinetics. Dipeptidyl peptidase-4 inhibitors exert unique pharmacologic actions via glucose-dependent mechanism and have an excellent tolerability profile with a very low risk of hypoglycemia. Furthermore, the literature reports that some dipeptidyl peptidase 4 inhibitors such as teneligliptin can be administered at the usual dose, regardless of a patient's level of renal impairment. In this article, we report a case of hypoglycemic coma with a blood glucose level of 23 mg/dL. The patient became fully conscious shortly after receiving a glucose injection; however, severe hypoglycemia recurred for approximately 1.5 days. It eventually disappeared on the discontinuation of teneligliptin, which was the only antidiabetic agent that he had received. The present case may provide deep insights into promoting the safe use of hypoglycemic agents in patients undergoing dialysis. PMID- 29581707 TI - Long noncoding RNA LINC01510 promotes the growth of colorectal cancer cells by modulating MET expression. AB - Background: Abnormal expression of long non-coding RNA (lncRNAs) often facilitates unrestricted growth of cancer cells. Long intergenic non-protein coding RNA 1510, an enhancer lncRNA (LINC01510), a lncRNA enhancer is upregulated in colorectal cancer (CRC), and its expression might relate to MET as revealed by lncRNA microarray data. However, the potential biological role of LINC01510 and its regulatory mechanism in CRC remain unclear. Therefore, we investigated the involvement of LINC01510 in the proliferation of CRC cells. Methods: Microarray analysis, In situ hybridization, colony formation assay, MTT assay, Western blotting, quantitative RT-PCR and flow cytometry were applied. The two-tailed Student's t test and analysis of variance or general linear model of single factor variable was used for statistical analyse. Results: In the present study, we found that LINC01510 was significantly upregulated in CRC tissues and cell lines. The LINC01510 expression level were associated with the clinicopathological grade and stage. Meanwhile, gain- and loss-of-function assays demonstrated that LINC01510 overexpression increased CRC cell proliferation, and promoted cell cycle progression from the G1 phase to the S phase. Further study indicated that LINC01510 was positively correlated with the expression of MET, and its effects were most likely at the transcriptional level. Conclusions: Taken together, our findings suggested that upregulation of LINC01510 contributes to the proliferation of CRC cells, at least in part, through the regulation of MET protein. LINC01510 could be a candidate prognostic biomarker and a target for new therapies in CRC patients. PMID- 29581706 TI - Treatment, outcomes, and demographics in sinonasal sarcoma: a systematic review of the literature. AB - Background: Sarcomas comprise a diverse group of soft tissue mesenchymal malignancies. The sinuses and nasal region are a relatively rare site of sarcomas. Methods: Retrospective review of the literature on sinonasal sarcomas from 1987-2017. Data were analyzed for demographics, treatment type, stage, and histopathologic type. Kaplan-Meier analysis was used to assess and compare survival. Results: A total of 198 cases of sinonasal sarcoma were identified and analyzed. The median age at diagnosis was 39 years. Overall 5-, 10-, and 20-year survival was 61.3%, 58.9%, and 49.1%, respectively, and disease-free 5-, 10-, and 20-year survival was 53.2%, 49.1%, and 38.3%, respectively. Lymph node metastasis was present at diagnosis in 3.0% of cases, and distant metastasis was present in 3.5% of cases. On univariate analysis T stage, overall stage, treatment type, histopathologic subtype, and presence of distant metastasis significantly affected survival. On multivariate analysis overall stage alone significantly predicted overall survival. Open vs. endoscopic surgery, total radiation dose, and presence of neck metastasis did not significantly affect survival. Combined modality treatment was associated with higher survival rates than single modality therapy. Conclusions: Sinonasal sarcoma is a relatively rare malignancy. Lower T and overall stage, lack of distant metastasis, and multimodality therapy were associated with improved survival. Certain histopathologic subtypes were associated with poorer survival. PMID- 29581708 TI - Study of the Influence of Age in 18F-FDG PET Images Using a Data-Driven Approach and Its Evaluation in Alzheimer's Disease. AB - Objectives: 18F-FDG PET scan is one of the most frequently used neural imaging scans. However, the influence of age has proven to be the greatest interfering factor for many clinical dementia diagnoses when analyzing 18F-FDG PET images, since radiologists encounter difficulties when deciding whether the abnormalities in specific regions correlate with normal aging, disease, or both. In the present paper, the authors aimed to define specific brain regions and determine an age correction mathematical model. Methods: A data-driven approach was used based on 255 healthy subjects. Results: The inferior frontal gyrus, the left medial part and the left medial orbital part of superior frontal gyrus, the right insula, the left anterior cingulate, the left median cingulate, and paracingulate gyri, and bilateral superior temporal gyri were found to have a strong negative correlation with age. For evaluation, an age-correction model was applied to 262 healthy subjects and 50 AD subjects selected from the ADNI database, and partial correlations between SUVR mean and three clinical results were carried out before and after age correction. Conclusion: All correlation coefficients were significantly improved after the age correction. The proposed model was effective in the age correction of both healthy and AD subjects. PMID- 29581709 TI - DCE-MRI Pharmacokinetic-Based Phenotyping of Invasive Ductal Carcinoma: A Radiomic Study for Prediction of Histological Outcomes. AB - Breast cancer is a disease affecting an increasing number of women worldwide. Several efforts have been made in the last years to identify imaging biomarker and to develop noninvasive diagnostic tools for breast tumor characterization and monitoring, which could help in patients' stratification, outcome prediction, and treatment personalization. In particular, radiomic approaches have paved the way to the study of the cancer imaging phenotypes. In this work, a group of 49 patients with diagnosis of invasive ductal carcinoma was studied. The purpose of this study was to select radiomic features extracted from a DCE-MRI pharmacokinetic protocol, including quantitative maps of ktrans, kep, ve, iAUC, and R1 and to construct predictive models for the discrimination of molecular receptor status (ER+/ER-, PR+/PR-, and HER2+/HER2-), triple negative (TN)/non triple negative (NTN), ki67 levels, and tumor grade. A total of 163 features were obtained and, after feature set reduction step, followed by feature selection and prediction performance estimations, the predictive model coefficients were computed for each classification task. The AUC values obtained were 0.826 +/- 0.006 for ER+/ER-, 0.875 +/- 0.009 for PR+/PR-, 0.838 +/- 0.006 for HER2+/HER2-, 0.876 +/- 0.007 for TN/NTN, 0.811 +/- 0.005 for ki67+/ki67-, and 0.895 +/- 0.006 for lowGrade/highGrade. In conclusion, DCE-MRI pharmacokinetic-based phenotyping shows promising for discrimination of the histological outcomes. PMID- 29581710 TI - Electrocardiographic measures of repolarization dispersion and their relationships with echocardiographic indices of ventricular remodeling and premature ventricular beats in hypertension. AB - Objective: To examine the relationship between Tpeak- Tend interval (Tpe) and Tpe/QT ratio with occurrence of ventricular premature beats (VPBs) and left ventricular remodeling in hypertension. Methods: A total of 52 patients with mild to moderate essential hypertension were included, undergoing echocardiography and 24-hours Holter monitoring. Ventricular remodeling was assessed by left ventricular mass index (LVMI) using the Devereux formula and diastolic function by transmitral E and A wave velocities and E/A ratio. Tpe was measured in the precordial leads. The end of the T wave was set by the method of the tangent to the steepest descending slope of the T wave. Results: Tpe and Tpe/QT in leads V2 (r = 0.33, P = 0.01; r = 0.27, P = 0.04 respectively) and V3 (r = 0.40, P = 0.002; r = 0.40, P = 0.003, respectively) correlated significantly with LVMI. A significant inverse relationship was observed between E/A ratio and QT (r = 0.33, P = 0.01), Tpe in V3 (r = -0.39, P = 0.003) and Tpe/QT in V3 (r = -0.31, P = 0.02). Tpe in V3, V5, mean Tpe and maximum Tpe with cut-off values of 60 ms, 59 ms, 62 ms and 71 ms, respectively, associated with the occurrence of ventricular premature beats. Conclusions: The repolarization parameters Tpe interval and Tpe/QT ratio correlate with LVMI and indices of left ventricular diastolic function and show better predictive values than traditional parameters such as QT interval and QT dispersion. Lead V3 is the best lead for measuring Tpe and Tpe/QT. These ECG indices can therefore be used in clinical practice to monitor LV remodeling and predict occurrence of VPBs. PMID- 29581711 TI - Dual versus single antiplatelet therapy for patients with long-term oral anticoagulation undergoing coronary intervention: a systematic review and meta analysis. AB - Objective: The main aim of this meta-analysis is to compare the efficacy and safety of dual versus single antiplatelet therapy for patients taking oral anticoagulation (OAC) after coronary intervention. Background: The optimal regimen remains controversial for patients taking OAC after coronary intervention. Methods: PubMed, Embase and Cochrane Central Register of Controlled Trials were searched for eligible studies including data of triple therapy (TT) versus OAC plus single antiplatelet therapy for patients requiring OAC after coronary intervention. The primary outcome was major adverse cardiac and cerebrovascular event (MACCE). The safety outcome was major bleeding. Results: Fourteen studies with 32,825 patients were included. Among prospective studies, patients with TT had a trend toward a higher risk of major bleeding [odds ratios (OR): 1.56, 95% confidence interval (CI): 0.98-2.49, P = 0.06] and a markedly higher risk of all-cause death (OR; 2.11, 95% CI: 1.10-4.06 P = 0.02) compared with OAC plus clopidogrel. Meanwhile, TT was associated with decreased risks of MACCE (OR: 0.63, 95% CI: 051-0.77 P < 0.0001), all-cause death (OR: 0.45, 95% CI: 0.20-0.97, P = 0.04), and stroke/transient ischemic attack (TIA)/peripheral embolism (PE) (OR: 0.29, 95% CI: 0.09-0.96, P = 0.04) compared with OAC plus aspirin. Conclusions: For patients requiring OAC after coronary intervention, OAC plus clopidogrel may bring more clinical net benefit than TT, whereas OAC plus aspirin should be the last choice. More large-size randomized control trials are needed to confirm these findings. PMID- 29581712 TI - Predictors of super-response to cardiac resynchronization therapy: the significance of heart failure medication, pre-implant left ventricular geometry and high percentage of biventricular pacing. AB - Background: Super-responders (SRs) are defined as patients who show crucial cardiac function improvement after cardiac resynchronization therapy (CRT). The purpose of this study is to identify and validate predictors of SRs after CRT. Methods: This study enrolled 201 patients who underwent CRT during the period from 2010 to 2014. Clinical and echocardiographic evaluations were conducted before CRT and 6 months after. Patients with a decrease in New York Heart Association (NYHA) functional class >= 1, a decrease in left ventricular end systolic volume (LVESV) >= 15%, and a final left ventricular ejection fraction (LVEF) >= 45% were classified as SRs. Results: 29% of the 201 patients who underwent CRT were identified as SRs. At baseline, SRs had significantly smaller left atrial diameter (LAD), LVESV, left ventricular end-diastolic volume (LVEDV) and higher LVEF than the non-super-responders (non-SRs). The percentage of patients using angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) was higher in SRs than non-SRs. Most SRs had Biventricular (BiV) pacing percentage greater than 98% six months after CRT. In the multivariate logistic regression analysis, the independent predictors of SRs were lower LVEDV [odd ratios (OR): 0.93; confidence intervals (CI): 0.90-0.97], use of ACEI/ARB (OR: 0.33; CI: 0.13-0.82) and BiV pacing percentage greater than 98% (OR: 0.29; CI: 0.16-0.87). Conclusion: Patients with a better compliance of ACEI/ARB and a less ectatic ventricular geometry before CRT tends to have a greater probability of becoming SRs. Higher percentage of BiV pacing is essential for becoming SRs. PMID- 29581713 TI - Effect of advanced age on plasma homocysteine levels and its association with ischemic stroke in non-valvular atrial fibrillation. AB - Background: Elevated homocysteine (Hcy) has been reported to be associated with cardiovascular events in atrial fibrillation (AF) patients, while the age-related expression pattern of plasma Hcy in AF remains unknown. The study was aimed to investigate the effect of advanced age on plasma Hcy levels and its association with ischemic stroke in non-valvular AF patients. Methods: A total of 2562 consecutive patients with non-valvular AF and 535 controls were enrolled and divided into six age groups. Plasma Hcy levels were analyzed among different age groups, and the effect of advanced age on Hcy was investigated. Results: Plasma Hcy levels did not show any difference among groups aged below 65 years, while it increased sharply in patients aged 65-74 years and aged over 75 years (15.7 +/- 4.6 umol/L, 17.1 +/- 4.9 umol/L, both P < 0.01 compared with the first four age groups). Hcy was much higher in AF patients than in controls at the same age group (all P < 0.05). The proportion of patients with hyperhomocysteinemia increased gradually with age from 32.3%, 29.2%, 31.2%, 32.4%, 45.9%, to 51.4% in six age groups. The concentration of Hcy in AF patients with ischemic stroke increased progressively with age, and was higher than those without stroke at the same age. Logistic regression analysis demonstrated that age 65-74 years [odds ratios (OR): 1.742, 95% confidence interval (CI): 1.223-2.482, P = 0.002] and age >= 75 years (OR: 2.637, 95% CI: 1.605-4.335, P < 0.001) were significantly independent predictors of elevated plasma Hcy levels. Conclusions: Advanced age was significantly associated with elevated Hcy levels, which may provide a possible explanation for the progressive increase in ischemic stroke especially in elderly AF patients.

PMID- 29581714 TI - Congenital left ventricular aneurysms and diverticula: an entity in search of an identity. AB - Congenital left ventricular aneurysm or diverticulum are rare cardiac malformations described in 809 cases since the first description in 1816, being associated with other cardiac, vascular or thoraco-abdominal abnormalities in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. In an experimental study, targeted knockdown of cardiac troponin T in the chick was performed at day 3, after the heart tube has formed. Morpholino treatment of gene TNNT2 at this stage led to the development of left ventricular diverticula (LVD) in the primitive left ventricular wall. Diagnosis of left ventricular aneurysms (LVA)/LVD can be made after exclusion of coronary artery disease, local or systemic inflammation or traumatic causes as well as cardiomyopathies. Clinically, most of LVA and LVD are asymptomatic or may cause systemic embolization, congestive heart failure, valvular regurgitation, ventricular wall rupture, ventricular tachycardia or sudden cardiac death. Diagnosis is established by imaging studies (echocardiography, magnetic resonance imaging or left ventricular angiography) visualizing the structural changes and accompanying abnormalities. Mode of treatment has to be individually tailored and depends on clinical presentation, accompanying abnormalities and possible complications, options include surgical resection (especially in symptomatic patients), anticoagulation after systemic embolization, radiofrequency ablation or implantation of an implantable cardioverter defibrillator (ICD) in case of symptomatic ventricular tachycardias, and occasionally combined with class I- or III-antiarrhythmic drugs. Cardiac death occurs usually in childhood, is significantly more frequent in LVA patients and caused by congestive heart failure in most of the cases, whereas patients diagnosed with LVD died more frequently from rupture of the LVD.

PMID- 29581720 TI - Adsorption Characteristics of Bixin on Acid- and Alkali-Treated Kaolinite in Aprotic Solvents. AB - The adsorption of bixin in aprotic solvents onto acid- and alkali-treated kaolinite was investigated. Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FT-IR, EDS, and BET N2. The effects of contact time and dye concentration on adsorption capacity and kinetics, electronic transition of bixin before and after adsorption, and also mechanism of bixin-kaolinite adsorption were investigated. Dye adsorption followed pseudo-second order kinetics and was faster in acetone than in dimethyl carbonate. The best adsorption results were obtained for KOH-treated kaolinite. In both of the solvents, the adsorption isotherm followed the Langmuir model and adsorption capacity was higher in dimethyl carbonate (qm = 0.43 mg/g) than in acetone (0.29 mg/g). The adsorption capacity and kinetics of KOH-treated kaolinite (qm = 0.43 mg/g, k2 = 3.27 g/mg.min) were better than those of HCl treated kaolinite (qm = 0.21 mg/g, k2 = 0.25 g/mg.min) and natural kaolinite (qm = 0.18 mg/g, k2 = 0.32 g/mg.min). There are shift in the band position of maximum intensity of bixin after adsorption on this adsorbent. Adsorption in this system seemed to be based essentially on chemisorption due to the electrostatic interaction of bixin with the strong basic and reducing sites of kaolinite. PMID- 29581721 TI - Feature Selection for Object-Based Classification of High-Resolution Remote Sensing Images Based on the Combination of a Genetic Algorithm and Tabu Search. AB - In object-based image analysis of high-resolution images, the number of features can reach hundreds, so it is necessary to perform feature reduction prior to classification. In this paper, a feature selection method based on the combination of a genetic algorithm (GA) and tabu search (TS) is presented. The proposed GATS method aims to reduce the premature convergence of the GA by the use of TS. A prematurity index is first defined to judge the convergence situation during the search. When premature convergence does take place, an improved mutation operator is executed, in which TS is performed on individuals with higher fitness values. As for the other individuals with lower fitness values, mutation with a higher probability is carried out. Experiments using the proposed GATS feature selection method and three other methods, a standard GA, the multistart TS method, and ReliefF, were conducted on WorldView-2 and QuickBird images. The experimental results showed that the proposed method outperforms the other methods in terms of the final classification accuracy. PMID- 29581722 TI - A Two-Stream Deep Fusion Framework for High-Resolution Aerial Scene Classification. AB - One of the challenging problems in understanding high-resolution remote sensing images is aerial scene classification. A well-designed feature representation method and classifier can improve classification accuracy. In this paper, we construct a new two-stream deep architecture for aerial scene classification. First, we use two pretrained convolutional neural networks (CNNs) as feature extractor to learn deep features from the original aerial image and the processed aerial image through saliency detection, respectively. Second, two feature fusion strategies are adopted to fuse the two different types of deep convolutional features extracted by the original RGB stream and the saliency stream. Finally, we use the extreme learning machine (ELM) classifier for final classification with the fused features. The effectiveness of the proposed architecture is tested on four challenging datasets: UC-Merced dataset with 21 scene categories, WHU-RS dataset with 19 scene categories, AID dataset with 30 scene categories, and NWPU RESISC45 dataset with 45 challenging scene categories. The experimental results demonstrate that our architecture gets a significant classification accuracy improvement over all state-of-the-art references. PMID- 29581723 TI - Optimum Extraction, Characterization, and Antioxidant Activities of Polysaccharides from Flowers of Dendrobium devonianum. AB - Response surface methodology (RSM) was employed to optimize the conditions for the ultrasonic-assisted extraction (UAE) of polysaccharides from the flowers of Dendrobium devonianum. The optimal conditions for the maximum yields of DDFPs are as follows: an extraction temperature of 63.13 degrees C, an extraction time of 53.10 min, and a water-to-raw material ratio of 22.11 mL/g. Furthermore, three fractions (DDFPs30, DDFPs50, and DDFPs70) were prepared from Dendrobium devonianum flowers polysaccharides (DDFPs) by the stepwise ethanol precipitation method. The DDFPs50 exhibited the highest antioxidant activity compared to the other fractions. The molecular weight, polydispersity, and conformation of these fractions were also characterized. In particular, the monosaccharide composition analysis of the DDFPs indicates that mannose and glucose are the primary components, similar to those of the D. officinale plant. This study provides a rapid extraction technology and essential information for the production of DDFPs, which could be potentially used as healthcare food. PMID- 29581725 TI - Comparison of the Screening Tests for Gestational Diabetes Mellitus between "One Step" and "Two-Step" Methods among Thai Pregnant Women. AB - Objective: To compare the prevalence and pregnancy outcomes of GDM between those screened by the "one-step" (75 gm GTT) and "two-step" (100 gm GTT) methods. Methods: A prospective study was conducted on singleton pregnancies at low or average risk of GDM. All were screened between 24 and 28 weeks, using the one step or two-step method based on patients' preference. The primary outcome was prevalence of GDM, and secondary outcomes included birthweight, gestational age, rates of preterm birth, small/large-for-gestational age, low Apgar scores, cesarean section, and pregnancy-induced hypertension. Results: A total of 648 women were screened: 278 in the one-step group and 370 in the two-step group. The prevalence of GDM was significantly higher in the one-step group; 32.0% versus 10.3%. Baseline characteristics and pregnancy outcomes in both groups were comparable. However, mean birthweight was significantly higher among pregnancies with GDM diagnosed by the two-step approach (3204 +/- 555 versus 3009 +/- 666 g; p=0.022). Likewise, the rate of large-for-date tended to be higher in the two step group, but was not significant. Conclusion: The one-step approach is associated with very high prevalence of GDM among Thai population, without clear evidence of better outcomes. Thus, this approach may not be appropriate for screening in a busy antenatal care clinic like our setting or other centers in developing countries. PMID- 29581724 TI - Behaviour of the Foramen Ovale Flow in Fetuses with Intrauterine Growth Restriction. AB - Background: Foramen ovale (FO) flow may be altered in IUGR. This study was designed to test this hypothesis. Methods: Forty pregnant women (24-38 weeks) were divided into 3 groups: group I (IUGR), group II (adequate growth and maternal hypertension), and group III (normal controls). Impedance across the FO was assessed by the FO pulsatility index (FOPI): (systolic velocity - presystolic velocity)/mean velocity. Statistical analysis utilized ANOVA, Tukey test, and ROC curves. Results: Mean FOPI in IUGR fetuses (n = 15) was 3.70 +/- 0.99 (3.15 4.26); in the group II (n = 12), it was 2.84 +/- 0.69 (2.40-3.28), and in the group III (n = 13), it was 2.77 +/- 0.44 (2.50-3.04) (p=0.004). FOPI and UtA RI were correlated (r = 0.375, p=0.017), as well as FOPI and UA RI (r = 0.356, p=0.024) and, inversely, FOPI and MCA RI (r = -0.359, p=0.023). Conclusions: The FO flow pulsatility index is increased in fetuses with IUGR, probably as a result of impaired left ventricular diastolic function. PMID- 29581726 TI - Estimation of leaf traits from reflectance measurements: comparison between methods based on vegetation indices and several versions of the PROSPECT model. AB - Background: Leaf biochemical composition corresponds to traits related to the plant state and its functioning. This study puts the emphasis on the main leaf absorbers: chlorophyll a and b ([Formula: see text]), carotenoids ([Formula: see text]), water ([Formula: see text]) and dry mater ([Formula: see text]) contents. Two main approaches were used to estimate [[Formula: see text] [Formula: see text], [Formula: see text], [Formula: see text]] in a non-destructive way using spectral measurements. The first one consists in building empirical relationships from experimental datasets using either the raw reflectances or their combination into vegetation indices (VI). The second one relies on the inversion of physically based models of leaf optical properties. Although the first approach is commonly used, the calibration of the empirical relationships is generally conducted over a limited dataset. Consequently, poor predictions may be observed when applying them on cases that are not represented in the training dataset, i.e. when dealing with different species, genotypes or under contrasted environmental conditions. The retrieval performances of the selected VIs were thus compared to the ones of four PROSPECT model versions based on reflectance data acquired at two phenological stages, over six wheat genotypes grown under three different nitrogen fertilizations and two sowing density modalities. Leaf reflectance was measured in the lab with a spectrophotometer equipped with an integrating sphere, the leaf being placed in front of a white Teflon background to increase the sensitivity to leaf biochemical composition. Destructive measurements of [[Formula: see text] [Formula: see text], [Formula: see text], [Formula: see text]] were performed concurrently. Results: The destructive measurements demonstrated that the carotenoid, [Formula: see text], and chlorophyll, [Formula: see text], contents were strongly correlated (r2 = 0.91). The sum of [Formula: see text] and [Formula: see text], i.e. the total chlorophyllian pigment content, [Formula: see text], was therefore used in this study. When inverting the PROSPECT model, accounting for the brown pigment content, [Formula: see text], was necessary when leaves started to senesce. The values of [Formula: see text] and [Formula: see text] were well estimated (r2 = 0.81 and r2 = 0.88 respectively) while the dry matter content, [Formula: see text], was poorly estimated (r2 = 0.00). Retrieval of [Formula: see text] from PROSPECT versions was only slightly biased, while substantial overestimation of [Formula: see text] was observed. The ranking between estimated values of [Formula: see text] and [Formula: see text] from the several PROSPECT versions and that derived using the VIs were similar to the ranking observed over the destructively measured values of [Formula: see text] and [Formula: see text]. Conclusions: PROSPECT model inversion and empirical VI approach provide similar retrieval performances and are useful methods to estimate leaf biochemical composition from spectral measurements. However, the PROSPECT model inversion gives potential access to additional traits on surface reflectivity and leaf internal structure. This study suggests that non-destructive estimation of leaf chlorophyll and water contents is a relevant method to provide leaf traits with relatively high throughput. PMID- 29581727 TI - Reference gene identification for reliable normalisation of quantitative RT-PCR data in Setaria viridis. AB - Background: Quantitative real-time polymerase chain reaction (RT-qPCR) is the key platform for the quantitative analysis of gene expression in a wide range of experimental systems and conditions. However, the accuracy and reproducibility of gene expression quantification via RT-qPCR is entirely dependent on the identification of reliable reference genes for data normalisation. Green foxtail (Setaria viridis) has recently been proposed as a potential experimental model for the study of C4 photosynthesis and is closely related to many economically important crop species of the Panicoideae subfamily of grasses, including Zea mays (maize), Sorghum bicolor (sorghum) and Sacchurum officinarum (sugarcane). Setaria viridis (Accession 10) possesses a number of key traits as an experimental model, namely; (i) a small sized, sequenced and well annotated genome; (ii) short stature and generation time; (iii) prolific seed production, and; (iv) is amendable to Agrobacterium tumefaciens-mediated transformation. There is currently however, a lack of reference gene expression information for Setaria viridis (S. viridis). We therefore aimed to identify a cohort of suitable S. viridis reference genes for accurate and reliable normalisation of S. viridis RT-qPCR expression data. Results: Eleven putative candidate reference genes were identified and examined across thirteen different S. viridis tissues. Of these, the geNorm and NormFinder analysis software identified SERINE/THERONINE-PROTEIN PHOSPHATASE 2A (PP2A), 5'-ADENYLYLSULFATE REDUCTASE 6 (ASPR6) and DUAL SPECIFICITY PHOSPHATASE (DUSP) as the most suitable combination of reference genes for the accurate and reliable normalisation of S. viridis RT-qPCR expression data. To demonstrate the suitability of the three selected reference genes, PP2A, ASPR6 and DUSP, were used to normalise the expression of CINNAMYL ALCOHOL DEHYDROGENASE (CAD) genes across the same tissues. Conclusions: This approach readily demonstrated the suitably of the three selected reference genes for the accurate and reliable normalisation of S. viridis RT-qPCR expression data. Further, the work reported here forms a highly useful platform for future gene expression quantification in S. viridis and can also be potentially directly translatable to other closely related and agronomically important C4 crop species. PMID- 29581728 TI - Design of a Conceptual Bumper Energy Absorber Coupling Pedestrian Safety and Low Speed Impact Requirements. AB - The car front bumper system needs to meet the requirements of both pedestrian safety and low-speed impact which are somewhat contradicting. This study aims to design a new kind of modular self-adaptive energy absorber of the front bumper system which can balance the two performances. The X-shaped energy-absorbing structure was proposed which can enhance the energy absorption capacity during impact by changing its deformation mode based on the amount of external collision energy. Then, finite element simulations with a realistic vehicle bumper system are performed to demonstrate its crashworthiness in comparison with the traditional foam energy absorber, which presents a significant improvement of the two performances. Furthermore, the structural parameters of the X-shaped energy absorbing structure including thickness (tu), side arc radius (R), and clamping boost beam thickness (tb) are analyzed using a full factorial method, and a multiobjective optimization is implemented regarding evaluation indexes of both pedestrian safety and low-speed impact. The optimal parameters are then verified, and the feasibility of the optimal results is confirmed. In conclusion, the new X shaped energy absorber can meet both pedestrian safety and low-speed impact requirements well by altering the main deformation modes according to different impact energy levels. PMID- 29581729 TI - National profile of foot orthotic provision in the United Kingdom, part 2: podiatrist, orthotist and physiotherapy practices. AB - Background: A national survey recently provided the first description of foot orthotic provision in the United Kingdom. This article aims to profile and compare the foot orthoses practice of podiatrists, orthotists and physiotherapists within the current provision. Method: Quantitative data were collected from podiatrists, orthotists and physiotherapists via an online questionnaire. The topics, questions and answers were developed through a series of pilot phases. The professions were targeted through electronic and printed materials advertising the survey. Data were captured over a 10 month period in 2016. Differences between professions were investigated using Chi squared and Fischer's exact tests, and regression analysis was used to predict the likelihood of each aspect of practice in each of the three professions. Results: Responses from 357 podiatrists, 93 orthotists and 49 physiotherapists were included in the analysis. The results reveal statistically significant differences in employment and clinical arrangements, the clinical populations treated, and the nature and volume of foot orthoses caseload. Conclusion: Podiatrists, orthotists and physiotherapists provide foot orthoses to important clinical populations in both a prevention and treatment capacity. Their working context, scope of practice and mix of clinical caseload differs significantly, although there are areas of overlap. Addressing variations in practice could align this collective workforce to national allied health policy. PMID- 29581730 TI - The impact of Rhodiola rosea on the gut microbial community of Drosophila melanogaster. AB - Background: The root extract of Rhodiola rosea has historically been used in Europe and Asia as an adaptogen, and similar to ginseng and Shisandra, shown to display numerous health benefits in humans, such as decreasing fatigue and anxiety while improving mood, memory, and stamina. A similar extract in the Rhodiola family, Rhodiola crenulata, has previously been shown to confer positive effects on the gut homeostasis of the fruit fly, Drosophila melanogaster. Although, R. rosea has been shown to extend lifespan of many organisms such as fruit flies, worms and yeast, its anti-aging mechanism remains uncertain. Using D. melanogaster as our model system, the purpose of this work was to examine whether the anti-aging properties of R. rosea are due to its impact on the microbial composition of the fly gut. Results: Rhodiola rosea treatment significantly increased the abundance of Acetobacter, while subsequently decreasing the abundance of Lactobacillales of the fly gut at 10 and 40 days of age. Additionally, supplementation of the extract decreased the total culturable bacterial load of the fly gut, while increasing the overall quantifiable bacterial load. The extract did not display any antimicrobial activity when disk diffusion tests were performed on bacteria belonging to Microbacterium, Bacillus, and Lactococcus. Conclusions: Under standard and conventional rearing conditions, supplementation of R. rosea significantly alters the microbial community of the fly gut, but without any general antibacterial activity. Further studies should investigate whether R. rosea impacts the gut immunity across multiple animal models and ages. PMID- 29581731 TI - MicroRNA-34a regulates proliferation and apoptosis of gastric cancer cells by targeting silent information regulator 1. AB - The present study aimed to identify whether microRNA (miRNA/miR)-34a regulates the proliferation and apoptosis of gastric cancer cells by targeting silent information regulator 1 (SIRT1). The expression of miR-34a and SIRT1 and cell viability was investigated in gastric cancer cells. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was applied to determine miR-34a expression in gastric adenocarcinoma, normal pericarcinomatous tissues, human normal gastric mucosa epithelial cell line GES and various gastric cancer cell strains. A bioinformatics method was then used to predict the target gene of miR 34a. A human miR-34a over expression lentiviral vector system was constructed and then used for transfection of the gastric cancer cell line SCG-7901 to determine the expression of SIRT1 mRNA and SIRT1 protein using RT-qPCR and western blot analysis. The MTT method and flow cytometry was used to measure cell proliferation and apoptosis. The relative expression of miR-34a in gastric cancer tissues was significantly decreased compared with that in normal tissues (P<0.01). miR-34a expression was also significantly decreased in low differentiated N2, N3 gastric cancer tissues (P<0.01). However, tumor size and filtration degree were not significantly associated with miR-34a expression. The relative expression of miR-34a was decreased in gastric cancer cells, especially in the SGC-7901 cell line (P<0.01) compared with the GES group. The relative expression of SIRT1 protein was decreased in the miR-34a group compared with the negative control (P<0.01). The rate of proliferation was significantly decreased, whereas the rate of apoptosis was significantly increased in the miR-34a group compared with the NC group (P<0.01). Therefore, the present results suggested that miRNA-34a serves a pivotal role in gastric cancer as a cancer suppressor gene by targeting SIRT1 to regulate the proliferation and apoptosis of gastric cancer cells. PMID- 29581733 TI - Decreased expression of sirtuin 3 protein correlates with early stage chronic renal allograft dysfunction in a rat kidney model. AB - Chronic renal allograft dysfunction (CRAD) is the primary factor affecting the long-term survival of patients who have undergone renal transplantation. Oxidative stress and inflammation serve an important role in the pathological damage caused by CRAD in the early post-transplantation phase. Previous studies have demonstrated that sirtuin 3 (sirt3) protects cells from oxidative stress and inflammation. A model of renal orthotopic transplantation was established in the current study and kidney samples were harvested from the rats 12 weeks following surgery. Compared with the control groups, there were significantly increased levels of serum creatinine, blood urea nitrogen and 24 h urinary protein in the allograft group (P<0.05). Pathological examinations indicated mononuclear cell infiltration and intimal proliferation in the allograft group, which had a higher Banff score compared with the control groups. There were increased levels of malondialdehyde, decreased sirt3 protein expression and decreased superoxide dismutase enzyme activity in the allograft group compared with the control groups (P<0.05). In addition, there was a negative correlation between the expression of sirt3 and 24 h urinary protein excretion, serum creatinine levels, tubulointerstitial mononuclear cell infiltration, smooth muscle cell migration in the vascular wall and Banff scores. Thus, sirt3 may serve an important protective role in the early stage of CRAD. PMID- 29581732 TI - Isolation, culture and induced differentiation of rabbit mesenchymal stem cells into osteoblasts. AB - Mesenchymal stem cells (MSCs) may be easily isolated from the bone marrow, and possess multi-lineage differentiation potential and various therapeutic applications. The differentiation of MSCs into osteoblasts is a complex process that is regulated by multiple internal and external factors. In the present study, the differentiation of MSCs isolated from rabbit bone marrow into osteoblasts using different osteoblast inductive media in the presence of dexamethasone, bone morphogenetic protein 2 (BMP-2), 1,25-dihydroxyvitamin D3, transforming growth factor beta (TGFbeta), platelet lysate and cyclooxygenase 2 (COX2), respectively. Alkaline phosphatase (ALP) activity, mineralization, collagen type (Ct) I and osteocalcin activities, and the mRNA and protein expression levels of vascular endothelial growth factor (VEGF), BMP-2 and Ct II were measured during the differentiation process in MSCs treated with different inducers. Rabbit MSCs were successfully isolated and were observed to be predominantly circular in shape after culture for 24 h. Following subculture for 5 days, the cells demonstrated a spindle shape. ALP, Ct I and osteocalcin activities were higher in cells cultured in dexamethasone, BMP-2 and TGFbeta compared with the activities in control cells. Following differentiation, the dexamethasone, BMP-2 and TGFbeta groups demonstrated significantly enhanced mineralization of MSCs detected by Alizarin Red S staining. The mRNA and protein expression levels of VEGF, BMP-2 and Ct II were significantly increased in the same groups compared with the levels in the control group. In conclusion, rabbit MSCs were successfully isolated from bone marrow and differentiated into osteoblasts indicated by raised ALP, Ct I and osteocalcin activities, mineralization and expression of osteogenesis-inducing genes and proteins. The present study revealed that dexamethasone, BMP-2 and TGFbeta have a positive effect on cell differentiation. PMID- 29581734 TI - MicroRNA-133b inhibits cell proliferation and promotes apoptosis by targeting cullin 4B in esophageal squamous cell carcinoma. AB - microRNAs (miRs) serve a role as modulators during carcinogenesis. It has been demonstrated that the expression of miR-133b is decreased in a variety of tumor tissues and cell lines and serves a suppressive role in the proliferation and apoptosis of different types of tumor cells. However, its effect on esophageal squamous cell carcinoma (ESCC) cells remains unclear. In the current study, the expression of mature miR-133b was measured using reverse transcription quantitative polymerase chain reaction and the results indicated that miR-133b was significantly downregulated in ESCC tissues and various ESCC cell lines. The overexpression of miR-133b significantly inhibited the proliferation and promoted the apoptosis of KYSE150 and Eca-109 cells. Furthermore, it was demonstrated that cullin 4B (CUL4B) promotes ESCC cell proliferation and inhibits apoptosis by activating the protein kinase B/glycogen synthase kinase 3beta/beta-catenin pathway. Taken together, these results demonstrate that miR-133b/CUL4B serves a tumor suppressive role during ESCC progression and may therefore be used as a potential target to treat patients with ESCC. PMID- 29581735 TI - Reverting doxorubicin resistance in colon cancer by targeting a key signaling protein, steroid receptor coactivator. AB - Although there have been notable improvements in treatments against cancer, further research is required. In colon cancer, nearly all patients eventually experience drug resistance and stop responding to the approved drugs, making treatment difficult. Steroid receptor coactivator (SRC) is an oncogenic nuclear receptor coactivator that serves an important role in drug resistance. The present study generated a doxorubicin-resistant colon cancer cell line, in which the upregulation/activation of SRC was responsible for drug resistance, which in turn activated AKT. Overexpression of receptor tyrosine kinase-like epidermal growth factor receptor and insulin-like growth factor 1 receptor also induced SRC expression. It was observed that doxorubicin resistance in colon cancer also induced epithelial to mesenchymal transition, a decrease in expression of epithelial marker E-cadherin and an increase in the expression of mesenchymal markers, including N-cadherin and vimentin. Additionally, the present study indicated that SRC acts as a common signaling node, and inhibiting SRC in combination with doxorubicin treatment in doxorubicin-resistant cells aids in reversing the resistance. Thus, the present study suggests that activation of SRC is responsible for doxorubicin resistance in colon cancer. However, further research is required to understand the complete mechanism of how drug resistance occurs and how it may be tackled to treat patients. PMID- 29581736 TI - miR-143-3p regulates cell proliferation and apoptosis by targeting IGF1R and IGFBP5 and regulating the Ras/p38 MAPK signaling pathway in rheumatoid arthritis. AB - It has been demonstrated that the deregulation of microRNAs (miRNAs) affects the development of rheumatoid arthritis (RA). The primary objective of the current study was to determine the role of miR-143-3p in the progression of RA. The expression of miR-143-3p in synovium taken from patients with RA was assessed by reverse transcription-quantitative polymerase chain reaction. The expression of miR-143-3p was higher in synovium tissues of RA than that of osteoarthritis (OA). The decreased expression of miR-143-3p suppressed cell proliferation and promoted apoptosis in vitro. In addition, inhibition of miR-143-3p decreased levels of inflammatory cytokines, as determined by an enzyme-linked immunosorbent assay. IGF1R and IGFBP5 were found to be the target genes of miR-143-3p, and it was demonstrated that miR-143-3p regulated the proliferation and apoptosis of MH7A cells by targeting IGF1R and IGFBP5. Furthermore, TNF-alpha treatment stimulated the Ras/p38 mitogen activated protein kinase (MAPK) signaling pathway, whereas miR-143-3p inhibition suppressed it. The results of the current study indicate that miR-143-3p may regulate cell proliferation and apoptosis by targeting IGF1R and IGFBP5 expression and regulating the Ras/p38 MAPK signaling pathways. Therefore, miR-143-3p may be a novel therapeutic target in RA. PMID- 29581737 TI - Chronic ethanol exposure induces SK-N-SH cell apoptosis by increasing N-methyl-D aspartic acid receptor expression and intracellular calcium. AB - It has been identified that chronic ethanol exposure damages the nervous system, particularly neurons. There is scientific evidence suggesting that neuronal loss caused by chronic ethanol exposure has an association with neuron apoptosis and intracellular calcium oscillation is one of the primary inducers of apoptosis. Therefore, the present study aimed to investigate the inductive effects of intracellular calcium oscillation on apoptosis in SK-N-SH human neuroblastoma cells and the protective effects of the N-methyl-D-aspartic acid receptor (NMDAR) antagonist, memantine, on SK-N-SH cell apoptosis caused by chronic ethanol exposure. SK-N-SH cells were treated with 100 mM ethanol and memantine (4 uM) for 2 days. Protein expression of NR1 was downregulated by RNA interference (RNAi). Apoptosis was detected by Annexin V/propidium iodide (PI) double-staining and flow cytometry and cell viability was detected using an MTS kit. Fluorescence dual wavelength spectrophotometry was used to determine the intracellular calcium concentration and the levels of NR1 and caspase-3 were detected using western blotting. NR1 mRNA levels were also detected using qPCR. It was found that chronic ethanol exposure reduced neuronal cell viability and caused apoptosis of SK-N-SH cells, and the extent of damage in SK-N-SH cells was associated with ethanol exposure concentration and time. In addition, chronic ethanol exposure increased the concentration of intracellular calcium in SK-N-SH cells by inducing the expression of NMDAR, resulting in apoptosis, and memantine treatment reduced ethanol-induced cell apoptosis. The results of the present study indicate that the application of memantine may provide a novel strategy for the treatment of alcoholic dementia. PMID- 29581738 TI - Effect of probucol on hemodynamics, rheology and blood lipid of diabetic retinopathy. AB - The effect of probucol in the treatment of diabetic retinopathy was investigated to analyze its impact on its hemodynamics, rheology and blood lipid. A total of 80 patients with diabetic retinopathy who were treated in the Ninth People's Hospital of Chongqing (Chongqing, China) from January 2015 to August 2016 were selected and divided into two groups by random number table, with 40 patients in each group. Control group was treated by conventional and intensive glycemic control and antihypertensive therapy, while observation group was orally administered with 0.375 g probucol twice a day on the basis of intensive therapy. Outpatient follow-up was performed to all the patients for 6 months, then, among the blood rheology, the changes in blood viscosity and erythrocyte aggregation indexes at different time points before and after intervention in the two groups were compared, mean blood flow velocities in renal artery, renal artery pulse indexes and renal artery resistance indexes at different time points were recorded, changes in blood lipid of the two groups before and after intervention were compared, and complication rates during the treatment were calculated. After intervention, the whole blood viscosity at high shear rate, whole blood viscosity at low shear rate and plasma viscosity in observation group were lower than those before intervention and lower than those in control group after intervention (P<0.05); The erythrocyte aggregation indexes in observation group were obviously increased compared with those in control group at 1 week, 1 month and 6 months after intervention (P<0.05). The mean blood flow velocities in renal artery in observation group were remarkably higher than those in control group at 1 week, 1 month and 6 months after intervention (P<0.05), while the renal artery pulse indexes and resistance indexes in observation group were lower than those in control group in the same period (P<0.05). In observation group, the levels of total cholesterol (TC), triglyeride (TG) and low density lipoprotein cholesterol (LDL-C) after intervention were decreased compared with those before intervention, while the level of high-density lipoprotein cholesterol (HDL-C) was increased. The levels of TC, TG and LDL-C in observation group were lower than those in control group after intervention, while the HDL-C level was higher (P<0.05). During the treatment, the total incidence of phlebitis, chills, fever, rash and maculopapule in observation group was obviously lower than that in control group. Probucol can significantly improve the hemodynamic and rheological indexes and lower blood lipid in the body, and is an effective medicine for diabetic retinopathy. PMID- 29581739 TI - Investigating the application of diving endoscopic technique in determining the extent of pituitary adenoma resection via the trans-nasal-sphenoidal approach. AB - The aim of the present study was to investigate the advantages and disadvantages of the diving endoscopic technique in pituitary adenoma surgery, and the application value in determining the extent of tumor resection. A total of 37 patients with pituitary adenoma initially underwent tumor resection under an endoscope-assisted microscope via standard trans-nasal-sphenoidal approach, and tumor cavity structure was observed by applying the diving endoscopic technique. Surgery was subsequently performed again under a microscope or endoscope. The diving endoscopic technique allowed surgeons to directly observe the structure inside a tumor cavity in high-definition. In the present study, 24 patients had pituitary macroadenomas or microadenomas that did not invade the cavernous sinus, and were considered to have undergone successful total resection. Among these patients, no tumor residues were observed through the diving endoscopic technique. Some white lichenoid or fibrous cord-like tissues in the tumor cavity were considered to be remnants of tumors. However, pathology confirmed that these were not tumor tissues. For tumors that invaded the cavernous sinus in 13 patients, observation could only be conducted under the angulation endoscope of the diving endoscope; i.e., the operation could not be conducted under an endoscope. The present study suggests that the diving endoscopic technique may be used to directly observe the resection extent of tumors within the tumor cavity, especially the structure of the tumor cavity inside the sella turcica. The present study also directly validates the reliability of pituitary adenoma resection under endoscope-assisted microscope. In addition, the diving endoscopic technique also allows the surgeon to observe the underwater environment within the sella turcica. PMID- 29581740 TI - Effects of low-level laser therapy following surgical extraction of the lower third molar with objective measurement of swelling using a three-dimensional system. AB - The aim of the present study was to evaluate and compare the effects of single- and two-dose low-level laser therapy (LLLT) on the postoperative swelling, trismus and pain of patients undergoing extraction of impacted mandibular third molars. In addition, edema was volumetrically measured with a 3dMD face system. A total of 45 patients were randomly divided into three treatment groups (15 patients in each group) as follows: Group 1, receiving routine management with ice application and serving as the control group; Group 2, receiving a single dose of LLLT immediately following surgery; and Group 3, receiving two doses of LLLT, immediately following surgery and on day 2 after surgery. In the present study, a gallium-aluminum-arsenide (0.3 W, 40 sec, 4 J/cm2) diode laser device was applied extraorally at the insertion point of the masseter muscle. The trismus, pain level and facial swelling of the patients were evaluated. The visual analog scale (VAS) was used to examine the pain degree, while a 3dMD face photogrammetric system was used to evaluate the volumetric alterations of the swelling. The results indicated no statistically significant differences in the mean swelling or trismus among the three groups. The mean VAS measurements did not differ significantly among the groups at postoperative day 2; however, significantly reduced VAS values were observed in Group 2 compared with Group 1 at postoperative day 7 (P<0.05). The present study demonstrated that, although single-dose or two-dose LLLT had beneficial effects on the swelling, trismus and pain level, a significant reduction was only observed in the pain level at postoperative day 7. PMID- 29581741 TI - Extract of Rhus verniciflua stokes protects against renal ischemia-reperfusion injury by enhancing Nrf2-mediated induction of antioxidant enzymes. AB - Ischemia-reperfusion injury (IRI) may cause acute kidney disease (AKD) by mediating the oxidative stress-induced apoptosis of parenchymal cells. The extract of Rhus verniciflua Stokes (RVS) is used as a traditional herbal medicine as it exhibits anti-oxidant, anti-apoptotic and anti-inflammatory properties. Therefore, the current study investigated the therapeutic effect and the underlying mechanism of RVS on IRI-induced AKD in vivo and in vitro. The current study assessed the effects of RVS on a mouse model of renal IRI and in hypoxic human renal tubular epithelial HK-2 cells. The results demonstrated that the IRI induced elevation of blood urea nitrogen, serum creatinine and lactate dehydrogenase was significantly attenuated by the intraoral administration of RVS (20 mg/kg/day) for 14 days prior to surgery. It was demonstrated that IRI surgery induced histological damage and cellular apoptosis in renal parenchyma, which were attenuated by pretreatment with RVS. Furthermore, in HK-2 cells incubated with 300 uM CoCl2 to induce chemical hypoxia, it was demonstrated that RVS treatment significantly inhibited cell death and the production of reactive oxygen species (ROS). Furthermore, RVS treatment upregulated the levels of endogenous antioxidant enzymes, including heme oxygenase-1 and catalase, as well as their upstream regulator nuclear factor erythroid 2-related factor 2, in HK-2 cells. Taken together, these results suggested that the intraoral administration of RVS induces a therapeutic effect on IRI-induced AKD. These effects are at least partly due to the attenuation of ROS production via upregulation of the antioxidant defense system in renal tubular cells. PMID- 29581742 TI - Methylene blue relieves the development of osteoarthritis by upregulating lncRNA MEG3. AB - Methylene blue (MB) is a long-term inhibitor of peripheral nerve axons, thereby alleviating or permanently eliminating pain. However, it remains unknown whether MB is safe and effective method of treating osteoarthritis (OA). MB was injected into the knee joints of rabbits and they were monitored for any histological structural changes. The results revealed no evident changes in the histological structure of the normal knee joint following injection of 1 mg/kg MB at 1, 4, 8 and 24 weeks post-injection. Compared with the vehicle control, MB treatment significantly enhanced the weight distribution and significantly decreased the swelling ratio of the rabbits. Additionally, levels of long non-coding RNA (lncRNA) maternally expressed 3 (MEG3) mRNA were significantly increased following treatment with MB, but the protein expression of P2X purinoceptor 3 (P2X3) was significantly suppressed compared with the vehicle control. The levels of interleukin (IL) 6, tumor necrosis factor (TNF)alpha, IL-1beta and IL-8 were significantly suppressed following MB treatment, indicating that MB protects against OA progression. It was also revealed that MEG3 overexpression significantly suppresses levels of P2X3 protein. ELISA indicated that the MEG3 induced reduction of IL-6, TNFalpha, IL-1beta and IL-8 expression was significantly reversed following P2X3 overexpression. Therefore, the results of the present study demonstrated that MB is an effective method of treating OA associated pain by upregulating lncRNA MEG3 levels. Additionally, lncRNA MEG3 relieves the OA-associated pain and inflammation in a rabbit model of OA by inhibiting P2X3 expression. PMID- 29581743 TI - Tripterygium wilfordii mitigates hyperglycemia-induced upregulated Wnt/beta catenin expression and kidney injury in diabetic rats. AB - Aberrant activation of the Wnt/beta-catenin pathway contributes to the development of diabetic nephropathy (DN); however, treatment with Tripterygium wilfordii (TW) may be beneficial for patients with DN. The aim of the present study was to evaluate the effect of TW on Wnt/beta-catenin expression in the kidneys of diabetic rats. Male Sprague-Dawley rats were randomly injected with vehicle (control) or streptozotocin to induce diabetes. Diabetic rats were then randomly treated with vehicle (sodium carboxymethyl cellulose; SCC), TW combined with SCC (8 or 16 mg/kg) or irbesartan (50 mg/kg) daily for 8 weeks. Metabolic parameter levels and renal pathological changes were examined. mRNA and protein expression of Wnt-1, glycogen synthase kinase (GSK)-3beta, beta-catenin, nuclear factor (NF)-kappaB and transforming growth factor (TGF)-beta1 in the kidneys of rats from all groups were measured. Compared with the DM group, metabolic parameters and morphological parameters, apart from blood glucose levels, were significantly improved in TW-treated rats (all P<0.01). Furthermore, levels of Wnt-1, beta-catenin, NF-kappaB-p65 and TGF-beta1 mRNA and protein were significantly reduced in the kidneys of TW-treated rats compared with DM rats, whereas levels of GSK-3beta mRNA and protein did not differ significantly between any of the groups; however, the expression of P-GSK-3beta protein was significantly decreased in the kidneys of TW-treated rats compared with the DM group. The protective effects of TW tended to be dose-dependent and were an improvement compared with irbesartan treatment in diabetic rats. Therefore, the results of the present study indicated that treatment with TW mitigated hyperglycemia-induced upregulated Wnt-1 and beta-catenin expression in kidney tissues and ameliorated diabetes-induced kidney injury in rats. PMID- 29581744 TI - Protective effect of Atriplex suberecta extract against oxidative and apoptotic hepatotoxicity. AB - Atriplex suberecta I. Verd is a known phytomedicinal species of Atriplex; however, studies into its bioactivity remain inconclusive. The in vitro and in vivo antioxidative and hepatoprotective potential of A. suberecta ethanol-extract (ASEE) was assessed in the present study. 1,1-diphenyl-2-picrylhydrazyl radical scavenging and beta-carotene bleaching assays revealed that ASEE possesses free radical scavenging and anti-lipid peroxidative activities. These results were supported by the in vitro protection of HepG2 hepatoblastoma cells via abating 2,7-dichlorofluorescein-activated oxidative and apoptotic molecules (caspase-3/ 7). In carbon tetrachloride-treated rats, the oral administration of ASEE significantly normalized serum biomarkers of liver function (serum glutamate oxaloacetate, serum pyruvate transaminase, alkaline phosphatase, gamma-glutamyl transferase and bilirubin) and the lipid profile (total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides and malondialdehyde), including tissue non-protein sulfhydryl and total protein levels. These results were also supported by liver histopathology, which demonstrated that the therapeutic effect of ASEE was comparable to silymarin. Furthermore, phytochemical analysis of ASEE revealed the presence of flavonoids, alkaloids, tannins and saponins. Rutin, an antioxidant flavonoid, was identified using the validated high-performance thin-layer chromatography method. In conclusion, this is the first report on the therapeutic potential of A. suberecta against chemical induced oxidative stress and liver damage. PMID- 29581745 TI - Rat vibrissa dermal papilla cells promote healing of spinal cord injury following transplantation. AB - Bone marrow mesenchymal stem cell (BMSC) transplantation is effective for repairing spinal cord injuries (SCIs); however, there are limitations of clinical BMSC applications. Previously, we reported that dermal papilla cells (DPCs) secrete brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor more actively than BMSCs. To analyze the therapeutic function of DPCs in SCI, primary DPCs and BMSCs were cultured from the same green fluorescence protein-transgenic rat. The cells were suspended in rat-tail collagen I and transplanted separately into completely transected spinal cord lesion sites. Grafted-cell survival was examined with a small animal in vivo imaging detection system, and lesion sites were examined histochemically. In vivo imaging revealed enhanced lesion filling and survival with DPC grafts compared with BMSC grafts on days 14 and 21 post-transplantation. Hematoxylin and eosin staining demonstrated that lesion area sizes in the two groups were not markedly different. In the DPC transplant group, more axons formed within the lesion sites. CD31-positive vessel-like structures were more abundant in lesion sites near the grafted cells in the DPC group. The results of the present study suggest that DPCs may be a valuable alternative source of stem cells for autologous cell therapy for the treatment of SCI. PMID- 29581746 TI - Utility of dermoscopy for evaluating the therapeutic efficacy of tacrolimus ointment plus 308-nm excimer laser combination therapy in localized vitiligo patients. AB - The aim of the present study was to assess the function of dermoscopy in evaluating the therapeutic efficacy of tacrolimus ointment plus 308-nm excimer laser combination therapy in patients with localized vitiligo. A total of 147 patients with localized vitiligo (progressive disease, n=92; stable period, n=55) were enrolled and received combination therapy for 12 weeks. The condition of the skin lesions was monitored by dermoscopy and visual observation. At the initial visit, skin lesions were observed in 61 progressive and 19 stable patients. Residual perifollicular pigmentation was more abundant in progressive-stage patients than in stable-stage patients, whereas the presence of perilesional hyperpigmentation was obviously lower in patients with progressive vitiligo. After 12 weeks of combination therapy, marked differences in residual perifollicular pigmentation were identified between the progressive- and stable stage patients. Dermoscopy and visual observation indicated that the 12-week treatment efficacy in patients with progressive disease was significantly higher than in those with stable disease and that assessment by dermoscopy was superior to visual observation at 8 or 12 weeks of treatment. Binary logistic regression analysis revealed that the disease stage, vitiliginous areas and disease course were risk factors associated with the treatment efficacy of the combination therapy. In conclusion, dermoscopy may be used as an effective means of vitiligo therapy assessment to provide an accurate and scientific evaluation of treatment efficacy for localized vitiligo patients. PMID- 29581747 TI - Gene expression analysis for pneumonia caused by Gram-positive bacterial infection. AB - Gram-positive bacteria are an important pathogenic factor for bacterial pneumonia. The aim of the present study was to identify the differentially expressed genes (DEGs) and to explore their associated pathways or expression patterns. Expression profiling of gene arrays from two independent datasets, GSE6269 and GSE35716, were downloaded from the Gene Expression Omnibus. The DEGs between peripheral blood samples from healthy controls and patients with bacterial pneumonia were identified. The Functional Annotation Tool in the Database for Annotation, Visualization and Integrated Discovery was used to annotate and analyze the DEGs in Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Multiple proteins were used to generate a protein-protein interaction (PPI) network. A total of 624 (621 annotated) were identified in the GSE6269 dataset and 398 (295 annotated) DEGs were identified in the GSE35716 dataset between pneumonia and healthy samples. A total of 40 common DEGs were identified between the 2 datasets, including 4 downregulated and 32 upregulated DEGs. In the GO category cellular component, melanosome was highly enriched among 11 genes; in the category biological process, the three most enriched items were regulation of ruffle assembly, negative regulation of calcium ion transport and necroptotic process. In the KEGG terms, only the nuclear factor kappaB signaling pathway (Homo sapiens 04064) was significantly enriched. In the PPI network, five genes (CCL4, TIMP metallopeptidase inhibitor 1, intercellular adhesion molecule 1, plasminogen activator, urokinase receptor and cathepsin B) were identified to have a high degree of interaction with other DEGs. In conclusion, these five genes may represent key genes associated with pneumonia caused by Gram-positive bacteria. All of these results provide primary information and basic knowledge to understand the mechanisms of the pathogenesis. PMID- 29581748 TI - Osteoporosis as an initial manifestation in a patient with Crohn's disease: A case report. AB - The present case report details a rare case of osteoporosis as the initial manifestation of Crohn's disease (CD). A 43-year-old male was referred to the Second Xiangya Hospital of Central South University (Changsha, China) for further examination of low back pain (LBP) without digestive symptoms. Bone mineral density (BMD) analysis indicated osteoporosis, particularly in the lumbar spine. Endoscopy revealed an inflamed and strictured ileocecal valve with less inflammation in the ascending, transverse colon, sigmoid colon and rectum, compatible with CD, which was in accordance with the appearance of an abdominal computed tomography scan. Duodenal-balloon enteroscopy indicated segmental ulceration and stricture in the jejunum, in accordance with CD. The patient was diagnosed with CD following examination. It was suspected that osteoporosis may be an extra-intestinal manifestation of CD. Steroids and biological agents were prescribed in sequence. LBP and BMD rapidly improved following treatment, and inflammatory markers returned to normal after 1.5 years of treatment. According to this case, osteoporosis with unknown causes should be considered as a possible sign of small intestinal CD. PMID- 29581749 TI - Multiple pelvic accessory spleen: Rare case report with review of literature. AB - Accessory spleen (AS) usually presents as an isolated asymptomatic mass of splenic tissue separated from the body of the actual spleen. Multiple pelvic ASs are more unusual than single pelvic AS. The present study reported on the rare case of multiple pelvic AS. A 39-year-old Chinese woman presented at our hospital with complaints of abdominal pain for one week. A large pelvic mass behind the uterus was identified on ultrasound examination. Multiple AS in the pelvis was primarily considered during the operation and confirmed by histopathological examination after the surgery. The literature in English language was also reviewed by retrieving studies on AS published over the past 30 years, and it was discussed how to diagnose and treat pelvic AS. In conclusion, to the best of our knowledge, the present study provided the first case report of multiple pelvic AS. The gynecologist should be aware of the rare possibility of an AS in patients with abdominal and pelvic complaints and/or a pelvic mass. Pelvic AS is generally determined during radiological investigations or during open or laparoscopic surgeries. PMID- 29581750 TI - beta-Endorphin attenuates collagen-induced arthritis partially by inhibiting peripheral pro-inflammatory mediators. AB - The classical analgesic pathway of opioids by binding their receptors in the nervous system is well known. However, little is known regarding opioid analgesia through the anti-inflammatory pathway. The present study aimed to investigate the analgesic and anti-inflammatory effect of beta-endorphin on inflammatory pain. A rat model of collagen-induced arthritis (CIA) was generated by intradermal injection of bovine type II collagen. Rats were divided into the CIA + saline group and the CIA + beta-endorphin group, in which rats were intraperitoneally injected with beta-endorphin once every other day from day 18 following the injection of CII until day 28. Thermal hyperalgesia as determined by tail flick latency (TFL), as well as paw arthritis index and swelling. Tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6 mRNA expression in synovial tissue and their protein levels in paw inflammatory tissue were measured. The rat CIA model was successfully induced as indicated by the significantly decreased TFL, increased paw arthritis index and percentage of swelling on day 18. beta endorphin treatment significantly increased the TFL, while decreasing the paw arthritis index and swelling in CIA rats. It also significantly downregulated TNF alpha and IL-1beta mRNA expression in synovial tissue and their protein levels in inflammatory tissue of the paws of CIA rats, while it had no significant effect on the levels of IL-6. These results indicated that beta-endorphin suppresses peripheral pro-inflammatory mediators in collagen-induced arthritis, which may contribute to its analgesic effect. PMID- 29581751 TI - Tumor suppressor miR-211-5p is associated with cellular migration, proliferation and apoptosis in renal cell carcinoma. AB - Increasing evidence has demonstrated that microRNA (miRNA) serve an important role in the tumorigenesis of various types of cancer, such as renal cell carcinoma (RCC). The expression of miR-211-5p has been detected in RCC tissue by microarray profiling. However, studies regarding miR-211-5p and RCC remain rare. In the present study, the expression of miR-211-5p in RCC tissues and cell lines was revealed to be downregulated by reverse transcription-quantitative polymerase chain reaction analyses. The present results also revealed that the upregulation or downregulation of miR-211-5p inhibited or promoted, respectively, RCC cell proliferation, migration and invasion. In addition, the upregulation or downregulation of miR-211-5p induced or inhibited, respectively, RCC cell apoptosis. However, the present study only identified that downregulation of miR 211-5p promoted 786O and ACHN cell viability. The above results suggest that miR 211-5p may be a tumor suppressor in the tumorigenesis of RCC and may be a potential therapeutic target for RCC in the future. Further research should focus on the underlying mechanism of miR-211-5p in RCC and on investigating the possible use of miR-211-5p as a biomarker for RCC. PMID- 29581752 TI - Enhanced antitumor activity of combined megestrol acetate and arsenic trioxide treatment in liver cancer cells. AB - Liver cancer is an aggressive malignancy with a very high fatality rate. Although megestrol acetate (MA) and arsenic trioxide (ATO) have shown an antitumor effect in liver cancer cells, the therapeutic benefits of MA or ATO alone in patients with liver cancer were limited. The aim of the present study was to elucidate whether the co-treatment of MA/ATO could enhance antitumor efficacy in liver cancer cell lines (Hep G2 and BEL 7402) and explore the underlying anti-cancer mechanisms. The cell viability, apoptotic response and expression levels of associated proteins were detected by Cell Counting Kit-8 assay, flow cytometry and western blotting, respectively. An xenograft model in nude mice bearing a Hep G2 tumor was used to estimate tumor growth in vivo. Co-treatment with MA/ATO markedly improved the inhibition of cell viability, enhanced apoptosis, and increased the phosphorylation of p38, c-Jun N-terminal kinase 1/2 and extracellular signal-regulated kinase 1/2 on liver cancer cell lines. Furthermore, the tumor growth in the murine Hep G2 cancer xenograft model was significantly inhibited by combined treatment with MA/ATO. The results indicated that MA/ATO combined treatment enhanced antitumor efficacy and possessed potential application for treating liver cancer. PMID- 29581753 TI - Knockdown of dickkopf2 inhibits vascular endothelia growth factor expression through the Wnt/beta-catenin signaling pathway in human retinal pigment epithelial cells under hypoxic conditions. AB - Hypoxia has been demonstrated to be a proangiogenic factor that induces vascular endothelial growth factor (VEGF) in retinal pigment epithelial (RPE) cells. Dickkopf2 (DKK2), originally known as Wnt antagonist, has recently been demonstrated to have an important regulatory role in angiogenesis; however, the specific role of DKK2 in RPE cells is not known. In the present study, the effects of DKK2 on VEGF expression under hypoxic conditions were investigated, as well as the molecular mechanisms involved. The results demonstrated that the expression of DKK2 was markedly increased under hypoxic conditions compared with normoxic conditions. Knockdown of DKK2 markedly attenuated the CoCl2-induced expression of hypoxia-inducible factor (HIF)-1alpha and VEGF in RPE cells. Furthermore, knockdown of DKK2 markedly inhibited the expression of beta-catenin induced by hypoxia. In conclusion, the findings of the present study demonstrate that knockdown of DKK2 inhibits the hypoxia-induced production of VEGF by suppressing the activation of the Wnt/beta-catenin signaling pathway. PMID- 29581755 TI - FOXG1 Expression Is Elevated in Glioma and Inhibits Glioma Cell Apoptosis. AB - FOXG1, a member of forkhead family transcriptional factor, is involved in telencephalon development. Recent studies showed FOXG1 was important for a variety of cellular events in cancer cells. In respect to glioma, FOXG1 has been shown to regulate cell proliferation and cell cycles. However, its impacts on other cellular events were not well studied. Here, we found FOXG1 had high expression in clinical glioma tissues, and its expression positively correlated with glioma malignancy. Moreover, we found FOXG1 played roles in glioma cell apoptosis. The expressions of caspase family members were significantly altered in response to change of FOXG1 expression, indicating a direct regulation of FOXG1 on caspase family members. These data strongly suggest FOXG1 is negative regulator of glioma cell apoptosis. PMID- 29581756 TI - The Optimal Application of Transrectal Ultrasound in Staging of Rectal Cancer Following Neoadjuvant Therapy: A Pragmatic Study for Accuracy Investigation. AB - Background: Transrectal ultrasound (TRUS) is a cost-effective test for preoperative assessment of rectal cancer. However, whether the accuracy of TRUS staging is correlated with tumor location remains obscured. This study is designed to explore their relationship and confirm an optimal application of TRUS in rectal cancer restaging. Methods: From 2005 to 2011, rectal cancer patients with TRUS data were retrospectively reviewed. Patients were divided into five groups according to tumor-involved rectal segment (SEG) above the anal verge: SEG I 1-3cm, II 3-6cm, III 6-9cm, IV 9-12cm, and V 12-16cm. The accuracy and long term outcomes of tumor staging were compared between ultrasonographic and pathological stages. Results: 219 patients were included, with 55 (25.1%) in SEG I, 123 (56.2%) in SEG II, 32 (14.6%) in SEG III, 4 (1.8%) in SEG IV and 5 (2.3%) in SEG V. The overall accuracy of TRUS staging was remarkably superior to clinical staging by CT (64.8% vs. 34.7%, P<0.001), with 70.3% and 82.2% for ultrasonographic T and N stages respectively. The accuracy of TRUS reached its peak value when tumors were located in SEG II. The 5-year overall survival had no significant difference between TRUS and pathology staging for all stages. A cox regression analysis indicated that high levels of CEA and tumor location were risk factors of inaccurate staging. Conclusions: TRUS is still a valuable examination for restaging of rectal cancer after neoadjuvant therapy. The application of TRUS would be optimal for rectal cancer located 3-6cm above the anal verge. PMID- 29581754 TI - Exosomes in Nasopharyngeal Carcinoma. AB - Exosomes are nanosized (30-100nm) membrane microvesicles secreted through a complex cellular process. Exosomes contain a variety of bioactive molecules, such as proteins, microRNAs(miRNAs or miRs) and long non-coding RNAs (lncRNAs), playing an important role in the cell-to-cell substance transportation and signal transduction. Nasopharyngeal carcinoma-related exosomes (NPC-Exo) have been identified in circulating blood and contribute to tumor cell proliferation, angiopoiesis, and immune tolerance through remodeling of tumor microenvironment (TME). Nasopharyngeal carcinoma-related exosomes may also induce epithelial mesenchymal transition (EMT), thus promoting tumor metastasis and chemoradioresistance. Clinically, the exosomes may serve as novel biomarkers for diagnosis and targeted therapies of nasopharyngeal carcinoma. This review article updates the understanding of exosomes in nasopharyngeal carcinoma(NPC). PMID- 29581757 TI - Serum expression level of IL-6 at the diagnosis time contributes to the long-term prognosis of SCLC patients. AB - Cytokines are vital mediators involved in tumor immunity. We aimed to explore whether the expression levels of IL-1beta, TNF-alpha and IL-6 have impacts on prognosis of SCLC patients. In this study, we concluded 707 non-operable SCLC patients at stage III or IV into this study and analyzed the relationships between interleukins and OS/PFS by cox regression analysis and Kaplan-Meier analysis (log-rank test). As a result, under current standard chemotherapy, SCLC patients with higher IL-6 expression level had a shortened OS compared with those with normal level (HR: 0.381, 95%CI: 0.177-0.822, p=0.014). Furthermore, IL-6 expression level contributed mostly to patients without a smoking history. Non smoking patients with a high IL-6 level showed a 6 months shortened OS than those with normal IL-6 level (10.50 vs 16.90 months, p=0.003 by Log-Rank test in Kaplan Meier analysis). IL-6 had no obvious impacts on first-line PFS in these SCLC patients. To conclude, IL-6 acts as an independent factor of long-term prognosis of SCLC patients under current therapy. PMID- 29581758 TI - A Prognostic Score for Nasopharyngeal Carcinoma with Bone Metastasis: Development and Validation from Multicenter. AB - Background: To establish a prognostic score based on clinical routine factors to stratify nasopharyngeal carcinoma patients with bone metastasis into risk groups with different survival rates. Materials and Methods: Total 276 patients from multicenter were retrospectively analyzed. Kaplan-Meier method and Cox regression were used to confirm independent risk factors, which were checked for internal validity by bootstrapping method. The prognostic score, deriving from the corresponding regression coefficients in Cox model, classified patients into low and high risk groups. Finally, two independent cohorts were used for external validation. Results: In development cohort, six risk factors were identified: age>46 year-old (point=1), N>0 stage (point=2), anemia (point=2), bone metastasis free interval<=12 months (point=1), without radiotherapy to primary sites (point=1), and without radiotherapy to first metastasis sites (point=1). The derived prognostic score divided patients into low (score, 0-4) and high (score, 5-8) risk groups, with highly significant differences of 5-year overall survival rates (high vs. low risk: 24.6% vs. 58.2%, HR 3.47, P<0.001). Two external validations presented congruent results. Conclusion: A feasible and applicative prognostic score was successfully established and validated to discriminate bone metastatic nasopharyngeal carcinoma into low/high risk groups, which will be useful for individual treatment. PMID- 29581759 TI - The value of preoperative Glasgow Prognostic Score and the C-Reactive Protein to Albumin Ratio as prognostic factors for long-term survival in pathological T1N0 esophageal squamous cell carcinoma. AB - Plenty of studies have confirmed the prognostic values of inflammation-based prognostic scores in many malignant tumors. In present study, we aim to explore whether these indexes has same prognostic values in patients with stage T1N0 esophageal squamous cell carcinoma (ESCC). The clinicopathological data of 160 consecutive patients with pathological stage T1N0 ESCC from January 2005 to December 2012 were collected retrospectively. As prognostic factors, the inflammation-based prognostic scores, including C-reactive protein (CRP), Glasgow prognostic score (GPS), prognostic index (PI), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and CRP to albumin ratio (CAR), were evaluated. The best cut-off values were determined by the receiver operating characteristic (ROC) curves. The median follow-up time was 71.8 months. During the follow-up period, 34 (21.3%) patients occurred postoperative recurrence and 30 (18.8%) tumor-related deaths were recorded. The best cut-off values of CRP, NLR, PLR and CAR were 1.090, 1.976, 103.200 and 0.023, respectively. After multivariate analysis, the GPS and CAR were identified as independently prognostic factors for overall survival (OS) (p=0.017 and 0.040, respectively). Of all 160 individuals, there were 86 (53.8%) and 85 (53.1%) patients classified into high GPS group (1-2) and elevated CAR group (>0.023), respectively. In addition, the GPS were positively associated with PI (p<0.000) and the levels of serum CRP (p<0.000), NLR (p=0.004), PLR (p=0.029) and CAR (p<0.000) and the above correlations were also observed between the CAR and other inflammation-based prognostic scores (all p<0.050, except for p=0.054 for PLR levels). The preoperative GPS and CAR were simple, inexpensive, readily available predictor for long-term survival in stage T1N0 ESCC patients who underwent esophagectomy. PMID- 29581760 TI - A New and Safe Mode of Ventilation for Interventional Pulmonary Medicine: The Ease of Nasal Superimposed High Frequency Jet Ventilation. AB - We use pulmonary interventional procedures for the diagnosis of pulmonary diseases either for benign or malignant lesions. Flexible bronchoscopy with or without radial endobronchial ultrasound, convex-probe endobronchial ultrasound and electromagnetic navigation are procedures performed in centers with experience in diagnostic pulmonary medicine. The method of sedation and ventilation is very important in order to avoid or handle with success complications. Proper respiration during pulmonary (or other interventional) procedures is a key factor. Apart from the proper sedation method we have to choose the proper ventilation method which decides respiratory movement. Superimposed high-frequency jet ventilation (SHFJV) is supposed to be safe and effective in clinical practice. Although this perception is commonly accepted, there is no study proving its safety on the basic of reliable data. We analyzed the data of 100 patients in different interventional settings (bronchoscopy with or without navigational approach, left atrial appendage closure (LAAC) or intracardiac catheterization) using nasal SHFJV. Mainly analyzed were capillary ABG-Data at the beginning and end of the intervention under sedation. The aim was to analyze if a risk scenario for the patient by using the nasal SHFJV can be derived by measuring the changes of pCO2, pO2, cBase Excess, cHCO3 and PH. Due to our data we conclude that this method of ventilation can be easily and safely used in interventional medicine for patients with all kind of comorbidities such as; chronic respiratory disease, lung cancer, interstitial lung disease, structural heart disease and heart failure. PMID- 29581761 TI - Discrimination between malignant and benign mass-like lesions from breast dynamic contrast enhanced MRI: semi-automatic vs. manual analysis of the signal time intensity curves. AB - Purpose: To investigate the performance of a new semi-automatic method for analyzing the signal time-intensity curve (TIC) obtained by breast dynamic contrast enhancement (DCE)-MRI. Methods: In the conventional method, a circular region of interest was drawn manually onto the map reflecting the maximum slope of increase (MSI) to delineate the suspicious lesions. The mean TIC was determined subjectively as one of three different wash-out patterns. In the new method, the lesion area was identified semi-automatically. The mean TIC was categorized quantitatively. In addition to the MSI, other quantitative parameters were calculated, including the signal intensity slope (SIslope), initial percentage of enhancement (Einitial), percentage of peak enhancement (Epeak), early signal enhancement ratio (ESER), and second enhancement percentage (SEP). The performances were compared with receiver operating characteristic (ROC) analysis and Wilcoxon's test. Results: For TIC categorization results, the diagnostic accuracy rates were 61.54% with the traditional manual method and 76.92% with the new method. For the mean MSI values from the manual method, the accuracy was 63.41%. For the mean TIC derived using the semi-automatic method, the diagnostic accuracy were 82.05% for SIslope, 67.31% for MSI, 61.53% for Einitial, 64.75% for Epeak, 64.74% for ESER, and 52.56% for SEP, respectively. For the lesion regions identified by the semi-automatic method, the diagnostic accuracy for above mentioned parameters were 80.13%, 69.87%, 61.54%, 63.47%, 64.74% and 55.13%, respectively. Conclusion: With respect to the analysis of TIC from breast DCE-MRI, the results demonstrated that the new method increased the diagnostic accuracy, and should be considered as a supplementary tool for distinguishing benign and malignant lesions. PMID- 29581762 TI - Ring finger protein 38 promote non-small cell lung cancer progression by endowing cell EMT phenotype. AB - Objectives: Ring finger protein 38 (RNF38), as an E3 ubiquitin ligase, plays an essential role in multiple biological processes by controlling cell apoptosis, cell cycle and DNA repair, and resides in chromosome 9 (9p13) which is involvement in cancer pathogenesis including lung cancer. However, its function in tumorigenesis remains unclear. Hence, this study set out to investigate the biological function and clinical implications of RNF38 in non-small cell lung cancer (NSCLC). Materials and Methods: Immunohistochemistry, quantitative real time polymerase chain reaction (qRT-PCR) and western blot were used to detect RNF38 protein and mRNA levels in NSCLC and corresponding paratumor tissues. Tissue microarrays (TMA) analysis of 208 NSCLC cases were used to evaluate the relationship between RNF38 expression and clinical implications. Prognostic value was assessed by Kaplan-Meier analysis and log-rank tests. Wound-healing assays, trans-well assays, colony formation assays and CCK8 were used to assess cell migration, invasion and proliferative ability respectively. The analysis of epithelial-to-mesenchymal transition (EMT) phenotype was carried out by immunofluorescence and western blot. Results: Our data revealed that elevated RNF38 expression were more common in NSCLC tissues than paired normal tissues in both mRNA (2.82 +/- 0.29 vs. 1.23 +/- 0.13) and protein (2.75 +/- 0.09 vs. 1.24 +/- 0.02) level. High levels of RNF38 expression were significantly associated with lymph node metastases, higher TNM stages (p=0.011), larger tumor size (p=2.09E-04) and predicted poor prognosis. RNF38 expression was inversely correlated with E-cadherin expression (P= 0.025). Moreover, downregulation of RNF38 impaired the proliferation, metastatic and invasive abilities in NSCLC cells. In addition, aberrant RNF38 expression could modulate the key molecules of EMT. Conclusions: Our results indicate that elevated expression of RNF38 is significantly associated with the proliferation and metastatic capacity of NSCLC cells, and RNF38 overexpression can serve as a biomarker of NSCLC poor prognosis. PMID- 29581763 TI - Cancer survival in patients from a hospital-based cancer registry, China. AB - Purpose: There are few reports on survival rate analysis from hospital-based cancer registries (HBCR) in China, although the National Center of Cancer Registry of China has launched such an effort with the mission to expand the scope of registration and follow-up. Our study aimed to evaluate survival and outcomes of cancer patients from a HBCR in eastern China. Methods: Active and passive follow-up methods were used to obtain information on survival status for all patients from Qidong City and Haimen City in the databases of our hospital based registrations from 2002 to 2014. Censor time for survival was 31st March, 2016. Survival probability was estimated using the life-table method with SPSS Statistics software, and comparison of significant differences in survival rates was tested by Wilcoxon (Gehan) statistic. Results: The outcomes of 5010 patients were identified in the follow-up for 5244 cases from Qidong and Haimen, with a follow-up rate of 95.65%, and a rate of lost to follow-up of 4.35%. The 1-, 3-, 5 , and 10-year observed survival (OS) rate in all-combined cancer sites were 59.80%, 37.70%, 30.82%, and 22.60%, respectively. The top 10 cancer sites in rank were cancers of lung, esophagus, liver, cervix, stomach, breast, colon-rectum, non-Hodgkin's lymphoma, nasopharynx, and ovary, with 5-year OS rates of 12.63%, 19.62%, 11.69%, 66.61%, 21.35%, 59.43%, 36.36%, 37.03%, 48.95% and 36.17%, respectively. Females experienced better survival than males for lung, esophageal, liver, nasopharyngeal and pancreatic cancers (P<0.05), but not for other sites (P>0.05). A significant difference was also found between males and females when all-sites were combined (P<0.01). There are significant differences (P<0.05) between the 2015 patients (from Qidong) and the 3001 patients (from Haimen) with 5-year OS rates of 32.72% vs 29.57%; no significant differences were found for 5-year OS rates for individual cancer sites (P>0.05) except for liver (P=0.0005) and ovary (P=0.0460) between the two cities. Younger patients had better prognosis, but significance was only seen in cervical (P=0.0102) and nasopharyngeal (P=0.0305) cancers. Conclusion: The survival rates of each site or of all sites-combined in this setting are consistent with those elsewhere in China and abroad. Discrepancies in overall survival could be affected by the proportion of sites with or without better prognosis. Hospital-based cancer survival is a better index to evaluate outcomes that reflect the levels of comprehensive treatment and improvement of medical and health services. PMID- 29581764 TI - The value of neutrophil-to-lymphocyte ratio for response and prognostic effect of neoadjuvant chemotherapy in solid tumors: A systematic review and meta-analysis. AB - Introduction: The neutrophil-to-lymphocyte ratio (NLR) has been found to be an indicator of poor prognosis in many tumour types. However, little is known about the relationship between the NLR and patients with tumours who receive neoadjuvant chemotherapy (NAC) in terms of response rate and prognostic ability. We thus performed this meta-analysis to further investigate this relationship. Methods: An electronic systematic literature search for articles published before September 2017 was performed to explore the association between the pretreatment NLR and outcome in patients treated with NAC. Data were extracted by the reported odds ratios (ORs) and hazard ratios (HRs) with their 95% confidence intervals (CIs) for the response rate and the survival outcome, respectively. The results were pooled using the random-effect or fixed-effect model. Results: Thirty-three studies were eventually included in our study, and all were published no earlier than 2011. An NLR that was higher than the cut-off was associated with a lower pathological complete response (pCR) rate in patients with cancer (OR = 1.72, 95% CI, 1.26-2.33). A lower NLR was associated with better overall survival (OS) (HR = 1.58, 95% CI, 1.34-1.86), cancer-specific survival (CSS) (HR = 2.22, 95% CI, 1.32-3.74), disease-free survival (DFS) (HR = 1.32, 95% CI, 1.10-1.59) and recurrence-free survival (RFS) (HR = 1.90, 95% CI, 1.50-2.40). Conclusion: Overall, an NLR lower than the cut-off value indicated a greater chance for pCR and may predict good survival outcomes after NAC for patients with solid tumours. The use of the NLR for risk stratification before NAC should be further demonstrated by future large-scale prospective studies. PMID- 29581765 TI - Overall survival and post-progression survival are potent endpoint in phase III trials of second/third-line chemotherapy for advanced or recurrent epithelial ovarian cancer. AB - Purpose: A growing number of treatment options and active compounds in treatments have led to better outcomes for patients with advanced or recurrent epithelial ovarian cancer. We examined the association between progression-free survival (PFS), post-progression survival (PPS) and overall survival (OS) in phase III trials of second- and third-line chemotherapy for advanced or recurrent epithelial ovarian cancer. We aim to determine whether PFS or PPS is a surrogate of OS so that we can decide progress of disease is optimal endpoint for ovarian cancer. Methods: We identified 22 trials conducted between January 1, 2000 through December 31, 2014 by literature search. We divided OS into PFS and PPS, and assessed the association between OS and PFS/PPS. We also examined whether the year of trial enrollment completion was associated with any variables. Results: The median PPS was slightly longer in recent trials compared to older trials (10.0 vs. 8.8 months). While PPS was strongly associated with OS (r = 0.88) in all trials, PFS was moderately correlated with OS (r = 0.72). The correlation between OS and PPS in recent trials (r = 0.93) was stronger than in older trials (r = 0.84). Conclusions: Our findings indicate that PPS is highly associated with OS in second/third-line chemotherapy for advanced or recurrent epithelial ovarian cancer, while the association between PFS and OS is moderate. We recommend using OS as primary endpoint for clinical trial of ovarian cancer, however PFS is still an optional endpoint. PMID- 29581766 TI - Large Intergenic Non-coding RNA-RoR Inhibits Aerobic Glycolysis of Glioblastoma Cells via Akt Pathway. AB - Reprogramming energy metabolism is a hallmark of malignant tumors, including glioblastoma (GBM). Aerobic glycolysis is often utilized by tumor cells to maintain survival and proliferation. However, the underlying mechanisms of aerobic glycolysis in GBM remain elusive. Herein, we demonstrated that large intergenic non-coding RNA-RoR (LincRNA-RoR) functioned as a critical suppressor to inhibit the aerobic glycolysis and viability of GBM cells. We found that LincRNA-RoR was markedly reduced in GBM tissues compared with adjacent non-tumor tissues from 10 cases of GBM patients. Consistently, LincRNA-RoR expression in GBM cells was significantly lower than that in normal glial cells. The aerobic glycolysis of GBM cells, as determined by the measurement of glucose uptake and lactate production, was impaired by LincRNA-RoR overexpression. Mechanistically, LincRNA-RoR inhibited the expression of Rictor, the key component of mTORC2 (mammalian target of rapamycin complex 2), to suppress the activity of Akt pathway and impair the expression of glycolytic effectors, including Glut1, HK2, PKM2 and LDHA. Finally, enforced expression of LincRNA-RoR reduced the proliferation of GBM cells in vitro, restrained tumor growth in vivo, and repressed the expression of glycolytic molecules in GBM xenografts. Collectively, our results underscore LincRNA-RoR as a new suppressor of GBM aerobic glycolysis with therapeutic potential. PMID- 29581767 TI - Inhibition of PI3K/AKT Signaling Pathway Radiosensitizes Pancreatic Cancer Cells with ARID1A Deficiency in Vitro. AB - Pancreatic cancer is among the most aggressive human cancers, and is resistant to regular chemotherapy and radiotherapy. The AT-rich interactive domain containing protein 1A (ARID1A) gene, a crucial chromatin remodeling gene, mutates frequently in a broad spectrum of cancers, including pancreatic cancer. Recent evidence suggests that ARID1A acts as tumor suppressor and plays an important role in DNA damage repair (DDR). However, the effect of ARID1A on the radiosensitivity of pancreatic cancer remains unclear. Herein, we investigated the involvement of ARID1A depletion in the radioresistance of pancreatic cancer cells, and explored the underlying mechanisms. The results reveal that knockdown of ARID1A enhances the radioresistance of pancreatic cancer cells through suppressing apoptosis, impairing G2-M checkpoint arrest, strengthening DDR, and accompanying activation of PI3K/AKT signaling pathway. Moreover, upon inhibition of PI3K/AKT pathway by PI3K-inhibitor LY294002 or AKT-inhibitor mk2206, the radiosensitivity of ARID1A deficient pancreatic cancer cells is improved in vitro via increased apoptosis and weakened DDR. Taken together, these data suggest that loss of ARID1A expression enhances radioresistance of pancreatic cancer through activation of PI3K/AKT pathway, which maybe a promising target for radiosensitization of ARID1A deficient pancreatic cancer. PMID- 29581768 TI - Characteristics and Treatment of Brain Metastases from Esophageal Squamous Cell Carcinoma. AB - Brain metastasis is very rare in esophageal squamous cell carcinoma (ESCC). We retrospectively analyzed 4494 patients diagnosed with ESCC between 2010 and 2015 at a single institute; 15 of these patients developed brain metastases. All 15 patients had neurologic symptoms and were diagnosed by imaging or biology. Of the 15 patients, 67% had a solitary brain lesion and 73% had lesions larger than 3 cm. After treatment of the brain lesions, including surgery (53%) or stereotactic radiotherapy with or without whole brain radiation (20%), the median progression free survival time and the 2-year overall survival rate calculated from diagnosis of brain metastasis were 14.4 months and 36%, respectively. A graded prognostic assessment (GPA) score > 2.0 was associated with significantly better overall survival. Patients with brain metastases from ESCC achieve good overall survival after appropriate treatment of the brain lesion(s); GPA score may represent a prognostic factor for treatment decision-making. PMID- 29581769 TI - Alteration of Serum IgG Galactosylation as a Potential Biomarker for Diagnosis of Neuroblastoma. AB - Background: Neuroblastoma (NB) is the most frequent pediatric malignant neoplasm that originates from embryonic neural crest cells. Urinary catecholamines in 24-h urine are most commonly analyzed for the diagnosis of neuroblastoma at good sensitivity; however, it is challenging to collect 24-h urine samples in a pediatric population. Therefore, development of more rapid, non-invasive and cost effective tools for the diagnosis of NB remains needed. Serum immunoglobulin G (IgG) galactosylation have been found highly associated with adult cancers in our previous study. Methods: To explore the potential use of serum IgG galactosylation in aiding diagnosis of neuroblastoma, serum IgG galactosylation profiles of 26 neuroblastoma cases and 30 age-matched non-malignant controls were analyzed by MALDI MS. The alteration of IgG galactosylation in neuroblastoma patients was measured by a Gal-ratio formula: G0/(G1+G2*2), calculating the relative intensities of agalactosylated N-glycan (G0) vs mono-galactosyl N-glycan (G1) and digalactosyl N-glycan (G2). Results: The results showed that IgG Gal ratios were significantly higher in neuroblastoma cases compared with non malignant controls (p=5.0*10-4). And the Gal-ratio data generated sensitivity and specificity of 84.62% and 60.00%, combined with an AUC (area under the curve) of 0.80. Conclusions: The analysis of serum IgG galactosylation distribution may play a suggestive role for neuroblastoma diagnosis, or serve as a potential biomarker for NB diagnosis. PMID- 29581770 TI - Targeting hepatocarcinogenesis model in C56BL6 mice with pan-aurora kinase inhibitor Danusertib. AB - Background: To elucidate the expression of Aurora kinases (AURK) and the anticancer effects of pan-aurora kinase inhibitor Danusertib in hepatocarcinogenesis model in C56Bl6 mice. Methods: Thirty mice C56Bl6 were randomly divided into Group A or control, Group B animals who underwent experimental hepatocarcinogenesis with diethylnitrosamine (DEN), and Group C animals with DEN-induced hepatocarcinogenenesis that treated with pan-aurora kinase inhibitor Danusertib. Primary antibodies for immunochistochemistry (IHC) included rabbit antibodies against Ki-67, DKK1, INCENP, cleaved caspase-3, NF kappaB p65, c-Jun, beta-catenin. Hepatocyte growth factor receptor (C-MET/HGFR) and Bcl-2 antagonist of cell death (BAD) serum levels were determined using a quantitative sandwich enzyme immunoassay technique. Results: Inhibition of AURK reduced the number of DEN-induced liver tumours. Apoptosis and proliferation was very low in both DEN-induced and anti- AURK groups respectively. The hepatocellular adenoma cells of DEN-treated mice uniformly had ample nuclear INCENP whereas in anti- AURK markedly decreased. Expression of beta-catenin, NF kB and c-Jun did not differ in liver tumors of both AURK -depleted and non depleted mice. Conclusions: Depletion of AURK reduced the number of DEN-induced hepatic tumours. However, their size did not differ significantly between the groups. PMID- 29581771 TI - Genome-wide Association Study (GWAS) of Germline Copy Number Variations (CNVs) Reveal Genetic Risks of Prostate Cancer in Chinese population. AB - Introduction: The associations between Prostate cancer (PCa) and germline copy number variations (CNVs) in genome-wide level based on Chinese population are unknown. The objective of this study was to identify possible PCa-risk associated CNV regions in Chinese population. Materials and Methods: We performed a genome wide association study for CNV in 1,417 PCa cases and 1,008 controls in Chinese population. Results: 7 risk-associated CNVs were identified for PCa after association analyses (P <7.2*10-6). Another 34 CNVs were found to be potentially risk-associated CNVs (P<0.05). Among the total 41 CNVs, 27 CNVs were risk variations and the other 14 were found to be protective of PCa. 25 of the CNVs (19 duplications and 6 deletions) were located in gene regions while 16 CNVs (9 duplications and 7 deletions) were located in intergenic regions. We identified a higher burden of gaining PCa-risk CNVs and a lower frequency of protective CNVs in cases than controls. Bioinformatics analyses suggested that genes related to PCa risk-associated CNVs were significantly enriched in some biological processes, cellular components and molecular functions. Conclusion: These results provided additional information of genetic risks for PCa. Several CNV regions involved actionable genes that might be potential gene for target therapy. Additional validation and functional studies are warranted for these results. PMID- 29581772 TI - CXCR4/CXCR7/CXCL12-Axis in Follicular Thyroid Carcinoma. AB - Background: Follicular thyroid carcinoma's (FTC) often benign course is partially due to adjuvant radioactive iodine (RAI) treatment. However, once the tumour has spread and fails to retain RAI, the therapeutic options are limited and the outcome is poor. In this subset of patients, the identification of novel druggable biomarkers appears invaluable. Here, we investigated the stage dependent expression and functional role of the C-X-C chemokine receptors type 4 and 7 (CXCR4/7) in FTC. Methods: CXCR4/7 expression was examined in 44 FTC and corresponding non-neoplastic thyroid specimens as well as 10 FTC distant metastases and 18 follicular adenomas using tissue microarray technology. Expression levels were correlated with clinicopathological variables as well as overall and recurrence free survival. Changes regarding cell cycle activation, tumour cell invasiveness and mRNA expression of genes related to epithelial mesenchymal transition (EMT) were investigated after treatment with recombinant human SDF1alpha/CXCL12 (rh-SDF1alpha) and CXCR4 antagonists AMD3100 and WZ811. Results: CXCR4/7 expression was associated with large tumour size, advanced UICC stage as well as shorter overall and recurrence free survival. CXCR4 was significantly higher expressed in distant metastases than in primary tumour cores. In addition, rh-SDF1alpha induced invasive growth, cell cycle activation and EMT, while CXCR4 antagonists significantly reduced FTC invasiveness in vitro. Conclusion: Here we provide first evidence of the biological importance of the CXCR4/CXCR7/CXCL12 axis in FTC. Our findings underscore the therapeutic potential of this chemokine receptor family in advanced FTC and offer new valuable insight into the oncogenesis of metastatic FTC. PMID- 29581773 TI - Epigenetic modification of SALL1 as a novel biomarker for the prognosis of early stage head and neck cancer. AB - This study examined Sal-like protein (SALL)1 methylation profiles in head and neck squamous-cell carcinoma (HNSCC) patients at diagnosis and follow-up, and evaluated their prognostic significance and value as a biomarker. SALL1 expression was examined in a panel of cell lines by quantitative reverse transcription PCR (qRT-PCR). Promoter methylation was determined by quantitative methylation-specific polymerase chain reaction (qMSP) and was compared to the clinical characteristics of 205 samples. SALL1 promoter methylation was associated with transcriptional inhibition and was correlated with disease recurrence in 31.7% of cases, with an odds ratio of 1.694 (95% confidence interval: 1.093-2.626; P = 0.018) by multivariate Cox proportional hazard regression analysis. SALL1 promoter hypermethylation showed highly discriminatory receiver operator characteristic curve profiles that clearly distinguished HNSCC from adjacent normal mucosal tissue, and was correlated with reduced disease-free survival in early stage T1 and T2 patients (log-rank test, P < 0.001). SALL1 methylation was significantly correlated with the methylation status of both SALL3 and CDH1. This study suggests that CpG hypermethylation is a likely mechanism of SALL1 gene inactivation, supporting the hypothesis that SALL1 might play a role in HNSCC tumorigenesis and could serve as an important biomarker. PMID- 29581774 TI - Tumor location is an independent predictive factor for distant metastasis and metastatic sites of rectal adenocarcinoma in patients receiving total mesorectal excision. AB - Background and Objectives: To evaluate the predictive factor for and patterns of distant metastasis in patients with rectal adenocarcinoma receiving total mesorectal excision (TME). Methods: We enrolled 217 consecutive patients who had histologically confirmed rectal adenocarcinoma and underwent surgery at Taipei Medical University- Wanfang Hospital between January 2000 and December 2014. TME was performed in all patients undergoing a sphincter-sparing procedure or abdominal perineal resection of rectal cancer. We performed univariate and multivariate Cox regression analyses of the distant metastasis rate in all patients to evaluate predictive factors. Overall survival (OS) rates were calculated using the Kaplan-Meier method, and Kaplan-Meier survival curves were compared using the log-rank test. Results: A multivariate Cox regression analysis of the distant metastasis rate in patients with rectal adenocarcinoma identified tumor locations and American Joint Committee on Cancer (AJCC) stages as prognostic risk factors. The adjusted hazard ratios (aHRs) of distant metastasis for the upper-third, middle-third, and AJCC stage I-II cancers were 0.08 (95% CI, 0.01-0.69; p = 0.021), 0.41 (95% CI, 0.15-0.99; p = 0.047), and 0.20 (95% CI, 0.10-0.66; p = 0.008), respectively. The 5-year lung metastasis rates among patients with upper-, middle-, and lower-third rectal cancers were 0%, 3.37%, and 13.33%, respectively (log-rank, p = 0.001), and the 5-year liver metastasis rates among patients with upper-, middle-, and lower-third rectal cancers were 2.12%, 9.10%, and 11.76%, respectively (log-rank, p = 0.096). The 5-year OS rates also differed with different rectal adenocarcinoma locations. The 5-year OS rates for upper, middle, and lower rectal cancers were 96%, 86%, and 64%, respectively (log rank, p < 0.001). Conclusion: A poor OS rate and high lung or liver metastasis rate were observed in distal rectal adenocarcinoma. Longer intensive surveillance of the chest, abdomen, and pelvis after TME in distal rectal adenocarcinoma could be necessary. PMID- 29581775 TI - Increased Paxillin expression in prostate cancer is associated with advanced pathological features, lymph node metastases and biochemical recurrence. AB - Purpose Paxillin regulates cell-cell adhesion, and altered Paxillin expression has been associated with human carcinogenesis. This study analyzed the association between Paxillin expression in prostate cancer (PCa) tissues with clinicopathological features, lymph node metastasis and biochemical PCa recurrence. Methods A total of 386 tissue specimens from PCa patients who received radical prostatectomy and 60 tissue specimens from benign prostatic hyperplasia (BPH) cases were collected to construct tissue microarrays, which were subsequently immunostained for Paxillin expression. Thirty positive lymph node tissue specimens and 10 healthy prostate tissue specimens were randomly selected for Paxillin immunostaining. Results The association between Paxillin expression, lymph node metastasis and biochemical PCa recurrence was analyzed. Paxillin expression was significantly higher in PCa than both normal and BPH tissues (P<0.001) and was correlated with preoperative prostate-specific antigen level, Gleason score, clinical tumor stage, lymph node metastasis, positive surgical margin, extracapsular extension and seminal vesicle invasion (P<0.05 for all). Logistic regression analysis showed that Paxillin and Gleason score were independent risk factors for PCa lymph node metastasis (P<0.05). The receiver operating characteristic (ROC) curve indicated that Paxillin expression (AUC=0.723) more accurately predicted PCa lymph node metastasis than Gleason score (AUC=0.692). Kaplan-Meier curve analysis showed that increased Paxillin expression was associated with shortened biochemical-free survival (BFS) after radical prostatectomy (P<0.001). Conclusion Paxillin was significantly upregulated in PCa compared with BPH and normal tissues and associated with lymph node metastasis and shortened BFS of PCa. Further study will investigate the underlying molecular mechanism and the role of Paxillin in PCa. PMID- 29581776 TI - Association of Smoking and XPG, CYP1A1, OGG1, ERCC5, ERCC1, MMP2, and MMP9 Gene Polymorphisms with the early detection and occurrence of Laryngeal Squamous Carcinoma. AB - A total of 200 smoking-related laryngeal carcinoma patients with pathology confirmation from the Eye and ENT Hospital and 190 high-risk smokers were included in a survey. All of the participants had a smoking index greater than 400 (cigarettes/day*year.) We obtained data on clinical and baseline characteristics, and peripheral blood was obtained and subjected to DNA extraction to analyse the correlation between smoking and the occurrence of laryngeal carcinoma. We selected candidate genes and SNP fragments that were found to be closely associated with smoking-related tumours in preliminary studies. The selected candidate genes were XPG, CYP1A1, OGG1, ERCC5, ERCC1, MMP2, and MMP9. We then performed SNP sequencing using Sequenom SNP detection technology. Target genes and single nucleotide polymorphism (SNP) fragments were evaluated to analyse the correlation between genotype or allele and smoking related laryngeal carcinoma and to identify susceptibility genes related to laryngeal carcinoma. The results included four main findings: (1) The smoking index differed significantly between laryngeal cancer patients and control subjects (P=0.0035). The risk of laryngeal cancer was increased among individuals with a smoking index greater than 600 cigarettes/day*year (P=0.03). (2) The smoking index was significantly correlated with the T, N and clinical stages (P<0.05). (3) The polymorphisms CYP1A1-rs1048943, rs4646421, and rs4646422 and MMP9-rs17577 were significantly associated with laryngeal squamous carcinoma (P<0.05). (4) After stratifying the subjects by smoking degree, the GT genotype of ERCC1-rs2298881 was associated with a significantly greater risk of laryngeal carcinoma among heavy smokers (P=0.04). The results suggest that smoking plays an important role in the occurrence and development of laryngeal squamous carcinoma; CYP1A1 and MMP9 might be susceptibility gene SNPs for smoking-related laryngeal carcinoma, and ERCC1 might play an important role in heavy smokers. The results of this study might help identify an early marker for the detection and prevention of laryngeal carcinoma. PMID- 29581777 TI - Prospective matched study on comparison of volumetric-modulated arc therapy and intensity-modulated radiotherapy for nasopharyngeal carcinoma: dosimetry, delivery efficiency and outcomes. AB - Background: The purpose of this study is to assess the feasibility of volumetric modulated arc therapy (VMAT) for nasopharyngeal carcinoma (NPC) patients by comparing the physical dosimetry, delivery efficiency and clinical outcomes with intensity-modulated radiotherapy (IMRT). Methods: A prospective matched study was performed for patients with newly diagnosed NPC who underwent VMAT or IMRT. The patients in two groups were equally matched in terms of gender, age, tumor stage and chemotherapy. The target coverage, homogeneity index (HI) and conformity index (CI) of the planning target volume (PTV), organs at risk (OARs) sparing, average treatment time and clinical outcomes were analyzed. Results: From June 2013 to August 2015, a total of 80 patients were enrolled in this study, with 40 patients in each group. The coverage of PTV was similar for both groups. D2 was observed slight difference only in early stage disease (T1-2) (VMAT vs. IMRT, 7494+/-109 cGy vs. 7564+/-92 cGy; p=0.06). The HI of VMAT group was better than that of IMRT group (p=0.001), whereas CI was slightly worse (p=0.061). The maximum doses received by the brain stem, spinal cord, and optic nerve of VMAT were higher than those of IMRT (p<0.05). But the irradiation volumes in healthy tissue were generally lower for VMAT group, with significant differences in V20, V25 and V45 (p<0.05). With regard to the delivery efficiency compared with IMRT (1160 +/- 204s), a 69% reduction in treatment time was achieved by VMAT (363 +/- 162s). Both groups had 5 cases of nasopharyngeal residual lesions after radiotherapy. The 2-year estimated local relapse-free survival, regional relapse free survival and locoregional relapse-free survival, distant metastasis-free survival, disease-free survival and overall survival were similar between two groups, with the corresponding rates of 100%, 97.4%, 97.4%, 90.0%, 90.0% and 92.4% in VMAT group, and 100%, 100%, 100%, 95.0%, 95.0% and 97.5% in IMRT group, respectively. Conclusions: Both VMAT and IMRT can meet the clinical requirements for the treatment of NPC. The short-term tumor regression rates and 2-year survival rates with the two techniques are comparable. The faster treatment time benefits of VMAT will enable more patients to receive precision radiotherapy. PMID- 29581778 TI - The anti-tumor effects of dual PI3K/mTOR inhibitor BEZ235 and histone deacetylase inhibitor Trichostatin A on inducing autophagy in esophageal squamous cell carcinoma. AB - The effect and regulation of autophagy-related proteins Beclin-1 and LC3 in esophageal squamous cell carcinoma have not been fully studied. The aim of this study was to assess the expression of Beclin-1 and LC3 in ESCCs, and to investigate the association between the two markers and clinicopathological characteristics as well as prognosis. Meanwhile, we explored the anti-tumor effect of the PI3K/mTOR dual inhibitor BEZ235 and the histone deacetylase inhibitor TSA on inducing autophagy in ESCC cells. Our study included 118 ESCC tumors and paired non-tumor esophageal mucosa tissues. Beclin-1 and LC3 expression were performed by immunohistochemistry. Human ESCC cells Eca-109 and TE-1 were treated with BEZ235 and TSA either alone or in combination in Vitro. The expression of both Beclin-1 and LC3 proteins were decreased significantly in ESCCs, but there was no significant relation between the expression of Beclin-1 and LC3 (P = 0.427). The negative expression of either Beclin-1 or LC3 was associated with advanced TNM stages (P = 0.006 and P<0.001, respectively). Patients with a high expression of Beclin-1 and LC3 predict better prognosis. In Vitro co-treatment with BEZ235 and TSA showed a synergistic effect on inhibition of ESCC cell viability and induction of autophagy with the increasing expressions of Beclin-1, LC3-II and the ratio of LC3-II/LC3-I. Our results demonstrated that the autophagy-related proteins Beclin-1 and LC3 were decreased in ESCCs and the low expression of the two markers predicted a worse prognosis. The co-treatment of BEZ235 and TSA significantly induced autophagy and enhanced anti-tumor activities, provided a new effective therapeutic target in ESCCs. PMID- 29581779 TI - IDH1/2 Mutations Predict Shorter Survival in Chondrosarcoma. AB - Background. Recent studies have shown that isocitrate dehydrogenase 1/2 (IDH1/2)- activating mutations occur in a variety of cancers, including acute myeloid leukaemia, gliomas, and chondrosarcomas (CHS)s. The effect of IDH1/2 mutation on overall survival (OS) has not been reported in CHS. The aim of our study was to assess the prevalence of known cancer-related gene mutations in CHS, as well as their prognostic role in patient survival. Methods. DNA from FFPE samples of 80 patients (F:M- 1:1.3; mean age: 58 years; range 27-86) with histologically confirmed CHS (G1:29; G2:34; G3:17) was subjected to library preparation with the Ion AmpliSeq Cancer Hotspot Panel v2 and sequenced on the PGM Ion Torrent. Results. Among the clinical features only histological grade influenced OS. Deep sequencing identified 1784 single nucleotide variants. Of them, 426 were considered to be pathogenic or probably pathogenic. Activating IDH1/2 mutations were found in 27 patients (34%) including 17 R132 IDH1 (21%), 10 R172 IDH2 (13%) and 3 R140 IDH2 variants (4%). Three patients had concurrent IDH1 and IDH2 mutations. The R140 IDH2 mutant has not been reported to date in CHS patients. OS for CHS patients with IDH1/2 mutations was significantly lower than in patients without mutations (93% vs 64%; p<0.001). No other genetic feature of the Cancer Hotspot Panel had an impact on OS. Conclusions. In CHS, IDH1/2-mutation status and the histological aggressiveness of the CHS are important predictors for OS. The R140 IDH2 may also be a novel target for the treatment of CHS patients. PMID- 29581780 TI - Switch of the ovarian cancer cell to a calcifying phenotype in the calcification of ovarian cancer. AB - OBJECTIVE: The main aim of this study was to study swith of the ovarian cancer cell to a calcifying phenotype in the formation of calcification in ovarian cancer, and to offer some help for ovarian cancer's diagnosis and differentiation therapy. METHODS: The mineralization of ovarian cancer cell lines SKOV3 was induced via calcification medium for 21 d in vitro. Alizarin red staining, von kossa staining, calcein fluorescence staining and ALP activity detection were used to identify mineralization in calcification model of ovarian cancer. Also, the changes of ultrastructure and the mineralization biomarkers after the induction of calcification medium were investigated by transmission electron microscopy and western blot, respectively. The SKOV3 cells migration behavior after the induction of calcification medium was evaluated by using transwell assay and scratch wound. Finally, mineralization biomarkers were verified in 40 cases of calcified ovarian cancer specimens and matched 40 non-calcified ovarian cancer tissues. RESULTS: Classical calcium salt detection methods confirmed that the culture of SKOV3 cells in calcification medium was an appropriate ovarian cancer calcification model in vitro. Transmission electron microscopy and western blot revealed respectively the presence of cells with morphological characteristics of osteoblasts and the upregulation of mineralization biomarkers expression in treatment group. Transwell assay and scratch wound showed the decreased SKOV3 cell migration in treatment group. In specimens, the calcification occurred predominantly in well-differentiated carcinomas and the expression of the BMP2 and OPN elevated in calcified group. CONCLUSION: Our study showed that the switch of the ovarian cancer cell to a calcifying phenotype in the formation of calcification in ovarian cancer. The calcified phenotypic transformation may inform the new prospective in ovarian cancer therapy. PMID- 29581781 TI - LASS2 regulates invasion and chemoresistance via ERK/Drp1 modulated mitochondrial dynamics in bladder cancer cells. AB - Mitochondria coordinated a lot of vital cellular processes of energy production and distribution. Change of mitochondrial functions has been implicated in cancer progression. The present study aims to investigate the involvement of mitochondria dynamics in LASS2 induced invasion and chemoresistance of bladder cancer cells. J82 and BIU87 cell lines were used for LASS2 plasmid transfection while siRNA knockdown was carried out in 5637 cell line. Matrigel invasion assay and Annexin V/PI staining demonstrated that LASS2 negatively regulated cancer cell invasion and chemoresistance. JC-1 staining suggested that LASS2 overexpression downregulated mitochondrial membrane potential. Mitotracker staining showed that LASS2 induced mitochondrial fusion and inhibited mitochondrial fission. In addition, LASS2 overexpression downregulated expression of mitochondrial fission protein p-Drp1 Drp1 and Fis1. While depletion of LASS2 exhibited the opposite effects. Drp1 inhibitor Mdivi abolished invasion and chemoresistance induced by LASS2 siRNA. Furthermore, we found that LASS2 overexpression could inhibit phosphorylation of ERK, which act upstream of Drp1. ERK inhibitor PD98059 suppressed Drp1 phosphorylation and abrogated the effects of LASS2 depletion. In conclusion, the present study demonstrated that LASS2 inhibits bladder cancer invasion and chemoresistance through regulation of ERK Drp1 induced mitochondrial dynamics. PMID- 29581782 TI - A Novel Risk prediction Model for Patients with Combined Hepatocellular Cholangiocarcinoma. AB - Backgrounds: Regarding the difficulty of CHC diagnosis and potential adverse outcomes or misuse of clinical therapies, an increasing number of patients have undergone liver transplantation, transcatheter arterial chemoembolization (TACE) or other treatments. Objective: To construct a convenient and reliable risk prediction model for identifying high-risk individuals with combined hepatocellular-cholangiocarcinoma (CHC). Methods: 3369 patients who underwent surgical resection for liver cancer at Zhongshan Hospital were enrolled in this study. The epidemiological and clinical characteristics of the patients were collected at the time of tumor diagnosis. Variables (P <0.25 in the univariate analyses) were evaluated using backward stepwise method. A receiver operating characteristic (ROC) curve was used to assess model discrimination. Calibration was performed using the Hosmer-Lemeshow test and a calibration curve. Internal validation was performed using a bootstrapping approach. Results: Among the entire study population, 250 patients (7.42%) were pathologically defined with CHC. Age, HBcAb, red blood cells (RBC), blood urea nitrogen (BUN), AFP, CEA and portal vein tumor thrombus (PVTT) were included in the final risk prediction model (area under the curve, 0.69; 95% confidence interval, 0.51-0.77). Bootstrapping validation presented negligible optimism. When the risk threshold of the prediction model was set at 20%, 2.73% of the patients diagnosed with liver cancer would be diagnosed definitely, which could identify CHC patients with 12.40% sensitivity, 98.04% specificity, and a positive predictive value of 33.70%. Conclusions: Herein, the study established a risk prediction model which incorporates the clinical risk predictors and CT/MRI-presented PVTT status that could be adopted to facilitate the diagnosis of CHC patients preoperatively. PMID- 29581783 TI - Effect of the oncolytic ECHO-7 virus Rigvir(r) on the viability of cell lines of human origin in vitro. AB - Background: The role of oncolytic viruses in cancer treatment is increasingly studied. The first oncolytic virus (Rigvir(r), ECHO-7) was registered in Latvia over a decade ago. In a recent retrospective study Rigvir(r) decreased mortality 4.39-6.57-fold in stage IB-IIC melanoma patients. The aims of the present study are to test the effect of Rigvir(r) on cell line viability in vitro and to visualize the cellular presence of Rigvir(r) by immunocytochemistry. Methods: The cytolytic effect of Rigvir(r) on the viability of FM-9, RD, AGS, A549, HDFa, HPAF II, MSC, MCF7, HaCaT, and Sk-Mel-28 cell lines was measured using live cell imaging. PBMC viability was measured using flow cytometry. The presence of ECHO-7 virus was visualized using immunocytochemistry. Statistical difference between treatment groups was calculated using two-way ANOVA. Results: Rigvir(r) (10%, volume/volume) reduced cell viability in FM-9, RD, AGS, A549, HDFa, HPAF-II and MSC cell lines by 67-100%. HaCaT cell viability was partly affected while Rigvir(r) had no effect on MCF7, Sk-Mel-28 and PBMC viability. Detection of ECHO 7 by immunocytochemistry in FM-9, RD, AGS, A549, HDFa, HPAF-II and Sk-Mel-28 cell lines suggests that the presence of Rigvir(r) in the cells preceded or coincided with the time of reduction of cell viability. Rigvir(r) (10%) had no effect on live PBMC count. Conclusions: The results suggest that Rigvir(r) in vitro reduces the viability of cells of human melanoma, rhabdomyosarcoma, gastric adenocarcinoma, lung carcinoma, pancreas adenocarcinoma but not in PBMC. The presence of Rigvir(r) in the sensitive cells was confirmed using anti-ECHO-7 antibodies. The present results suggest that a mechanism of action for the clinical benefit of Rigvir(r) is its cytolytic properties. The present results suggest that the effect of Rigvir(r) could be tested in other cancers besides melanoma. Further studies of possible Rigvir(r) entry receptors are needed. PMID- 29581784 TI - Autophagy Inhibition Stimulates Apoptosis in Oesophageal Squamous Cell Carcinoma Treated with Fasudil. AB - Fasudil has been proven to be a promising chemotherapeutic drug for various malignancies. However, the potential anticancer effects of fasudil in oesophageal squamous cell carcinoma (ESCC) remain to be established. We confirmed the RhoA activity is inhibited by fasudil in ESCC cells. Then measured the effects of fasudil on apoptosis and autophagy in ESCC. Our study showed fasudil could both induce ESCCs apoptosis and autophagy, and when fasudil-induced autophagy was inhibited by knockdown of the essential autophagy genes (Beclin 1 or ATG7), and pharmacologic agent (chloroquine) treatment, both treatments also significantly sensitized ESCC to fasudil-induced apoptosis, reducing cell viability in vitro. Our study showed autophagy inhibitors combined with fasudil could significantly induce ESCC apoptosis, which may provide a novel therapeutic strategy for ESCC. PMID- 29581785 TI - A Meta-Analysis: Methylenetetrahydrofolate Reductase C677T Polymorphism in Gastric Cancer Patients Treated with 5-Fu Based Chemotherapy Predicts Serious Hematologic Toxicity but Not Prognosis. AB - 5-fluorouracil (5-Fu) metabolism associated enzyme, methylenetetrahydrofolate reductase (MTHFR)'s polymorphism C677T can affect enzyme activity and a series of studies have been performed to examine the association of this MTHFR polymorphism with the clinical outcomes of gastric cancer (GC) patients treated with 5-Fu based chemotherapies. However, the results are inconsistent and inconclusive. Therefore, a more comprehensive summary like meta-analysis on this topic is needed. We performed a systematic literature search of PubMed and Embase up to May 20, 2017. Researches exploring MTHFR polymorphisms C677T's relationship with the clinical outcomes (response rate, overall survival and toxicity) of GC patients treated with 5-Fu based chemotherapy were included. The association was measured by odds ratios (ORs) or hazard ratios (HRs) combined with their 95% confidence intervals (CIs) using random/fixed effects model according to the studies' heterogeneity. Subgroup, sensitivity and publication bias analyses were conducted. Thirteen studies were finally included in this meta-analysis. No significant association was found between response rate [TT/ (CC+CT) OR=1.31, 95% CI: 0.62-2.76] or overall survival [(CT+TT)/CC HR=1.05, 95% CI: 0.86-1.26; TT/(CT+CC) HR=1.48, 95% CI: 0.53-4.15] and MTHFR polymorphism C677T. However, GC patients with CC or CT genotype tended to experience less severe hematologic toxicity than those with TT genotype [(CC+CT)/TT OR=0.66, 95% CI: 0.48-0.91]. In conclusion, MTHFR C677T polymorphism predicts severe hematologic toxicity in GC patients receiving 5-Fu based chemotherapy, but not the efficiency. PMID- 29581786 TI - Genetic variations in the PI3K/PTEN/AKT/mTOR pathway predict tumor response and disease-free survival in locally advanced rectal cancer patients receiving preoperative chemoradiotherapy and radical surgery. AB - Objective: Although preoperative chemoradiotherapy (CRT) followed by total mesorectal excision (TME) is the standard treatment for locally advanced rectal cancer (LARC), the clinical efficacy differs among patients. This study was conducted to determine the association between genetic variations in the PI3K/PTEN/AKT/mTOR pathway and clinical outcomes in LARC patients. Methods: Sixteen tagging single-nucleotide polymorphisms (SNPs) in five core genes (PIK3CA, PTEN, AKT1, AKT2, and FRAP1) were genotyped. The associations of these SNPs with tumor response to preoperative CRT, postoperative disease-free survival (DFS) and overall survival (OS) were identified. Crude odds ratios (ORs) and hazard ratios (HRs) were adjusted by age, sex, clinical stage, tumor differentiation, tumor location, cycles of preoperative chemotherapy and time interval from CRT completion to surgery. Results: In an analysis of 97 LARC patients, the G/T+G/G genotype of AKT1:rs2498804 was associated with an increased tumor response rate (adjusted OR = 2.909, 95% confidence interval (CI), 1.127 7.505, P = 0.027). At a median of 65.7 months of follow-up, the G/C+C/C genotype of AKT2:rs8100018 was associated with a reduced risk of postoperative recurrence (adjusted HR = 0.414; 95% CI, 0.187-0.914, P = 0.029). Patients carrying the G/C+C/C genotype in AKT2:rs8100018 presented a higher 5-year DFS rate than those with the wild-type genotype (79.2% vs. 62.3%, P = 0.038). None of the SNPs were significantly associated with pathological complete response (pCR) or 5-year OS. Conclusions: The current study indicates that genetic variations within the PI3K/ PTEN/AKT/mTOR signaling pathway are associated with the clinical outcomes of LARC patients undergoing preoperative CRT followed by radical surgery. PMID- 29581787 TI - SULT1E1 inhibits cell proliferation and invasion by activating PPARgamma in breast cancer. AB - Sulfotransferase family 1E member 1 (SULT1E1) is known to catalyze sulfoconjugation and play a crucial role in the deactivation of estrogen homeostasis, which is involved in tumorigenesis and the progression of breast and endometrial cancers. Our previous study has shown that the protein levels of SULT1E1 were decreased in breast cancer; however, the underlying mechanism is still poorly understood. In this study, we explored the functional and molecular mechanisms by which SULT1E1 influenced breast cancer. Here, we identified that overexpression of SULT1E1 inhibited breast cancer cell growth through inducing apoptosis and arresting cell cycle progression. Furthermore, enforced expression of SULT1E1 suppressed tumor cell migration and invasion. Moreover, we found that the activation of PPARgamma was required for SULT1E1-mediated downregulation of C myc, Cyclin D1, MMP-2 and MMP-9 as well as for cell apoptosis, migration and invasion. In addition, the overexpression of SULT1E1 significantly inhibited tumor growth in vivo. Taken together, our findings indicated that SULT1E1 performed its tumor suppressor characteristics by activating PPARgamma, which provided a novel target for patients with breast cancer. PMID- 29581788 TI - Increased HE4 mRNA Expression Correlates with High Level Of eIF3a mRNA And Better Survival in Women with Epithelial Ovarian Cancer. AB - Human epididymis protein 4 (HE4) is one of the most promising biomarkers for epithelial ovarian cancer (EOC). The majority of previous studies utilized the serum level or tissue protein expression of HE4 based upon immunohistochemistry (IHC) to evaluate the role of HE4 in the diagnosis, prognosis, and surveillance of EOC, but very little is known about HE4 mRNA expression. Eukaryotic translation initiation factor 3a (eIF3a) is implicated in oncogenesis and has been investigated extensively as a potential biomarker for malignancy. We previously reported a positive correlation between IHC expressions of eIF3a and HE4 in EOC. In the present study, we performed RT-PCR to determine mRNA expressions of HE4 and eIF3a in 30 normal ovarian tissues, 45 benign, 20 borderline and 94 malignant ovarian tumors. The association of HE4 and eIF3a mRNA expressions with clinicopathological characteristics and patient survivals was investigated. IHC was also performed in the same participants to investigate the correlation between mRNA and protein levels of HE4. HE4 mRNA level was found to be 48.42 +/- 74.55 (mean +/- SD, range: 0.01-343.99), significantly higher in primary EOC than in the borderline tumor, benign tumor, and normal ovarian tissue (P<0.001). The cutoff value was 13.99 for HE4 to discriminate malignant from benign tumors at 68.1% sensitivity and 93.0% specificity. By Spearman's correlation test, HE4 mRNA expression was indicated to positively correlate with serum CA125 level (r=0.530, P<0.001). Higher HE4 mRNA expression was associated with decreased frequency of lymph node metastasis (P=0.038) and better overall survival (OS) (P=0.007) in primary EOC. Multivariable analysis showed an independent prognostic value of the relative mRNA level of HE4 greater than one for OS (Hazard Ratio, 0.069, 95%CI, 0.009-0.530, P=0.010). eIF3a mRNA expression in women with primary EOC was 0.95 +/- 1.19 (mean +/- SD, range: 0.06-7.46), which was in a positive linear correlation with HE4 mRNA expression (r=0.310, P=0.002). In the present study, the HE4 mRNA level was unparalleled with IHC expression of HE4 (P>0.05). Collectively, our study revealed that increased HE4 mRNA expression correlates with high level of eIF3a mRNA and better survival in women with EOC, which calls for further investigations. PMID- 29581790 TI - Surgical Treatment of Combined Hepatocellular-Cholangiocarcinoma is as Effective in Elderly Patients as it is in Younger Patients: A Propensity Score Matching Analysis. AB - Aims: To compare the long-term prognosis of younger and elderly patients with combined hepatocellular-cholangiocarcinoma (CHC) who underwent curative resection between 1993 and 2014 at our center. Methods: Two hundred and thirteen patients who underwent liver resection for CHC were enrolled in our study. The overall survival (OS) and disease-free survival (DFS) of elderly patients (age>=60, n=52) and younger patients (age<60, n=161) were compared by multivariate analysis and propensity score matching (PSM) analysis. Results: Among the 213 CHC patients, the elderly patients had a higher rate of worse Child-Pugh grade (P=0.027), abnormal serum albumin (P<0.001) and lymphoid metastases (P=0.024). The proportion of HBV-positive CHC patients (74.6%, 159/213) was much higher than that observed in healthy cohorts. Younger patients had a higher rate of hepatitis B virus (HBV) infection compared to older patients (83.9% vs 46.2%, P<0.001). OS and DFS of the elderly and younger patients before and after propensity score matching were comparable. Conclusion: Elderly and younger patients who underwent liver resection for CHC have comparable long-term OS and DFS. PMID- 29581789 TI - Integrated Oncogenomic Profiling of Copy Numbers and Gene Expression in Lung Adenocarcinomas without EGFR Mutations or ALK Fusion. AB - Targeted therapies based on EGFR mutations or on the ALK fusion oncogene have become the standard treatment for certain patients with lung adenocarcinoma (LUAD). However, most LUAD patients have no EGFR mutation or ALK fusion, and their oncogenetic alterations remain to be characterized. Here we conducted an integrated analysis of public datasets to assess the genomic alterations of 23 highly lung cancer-associated genes. The copy numbers of these genes were measured in ten micro-dissected, paired tumors and normal lung tissues of LUAD patients without EGFR mutations or ALK fusion. The copy numbers of PTEN, RB1, HMGA2, and PTPRD were lower in tumors compared with those for normal tissues. Although there were reduced mRNA levels of PTEN and RB1 in tumors, there was a correlation between copy number and expression only for PTEN. In addition, analysis of the copy number alterations of these 23 genes revealed correlations between EMSY/CCND1, EMSY/PIK3CA, CCND1/CDKN2A, and CCND1/PIK3CA. Our exploration of integrated copy number and gene expression analysis gives priority to the PTEN PIK3CA and RB1-CCND1 pathways in developing therapeutic strategies for LUAD patients without EGFR mutations or ALK fusion. PMID- 29581791 TI - Usefulness of Bronchoscopic Rebiopsy of Non-Small Cell Lung Cancer with Acquired Resistance to Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitor. AB - Background: Approximately 50% of non-small cell lung cancer (NSCLC) patients with acquired resistance to EGFR-TKI harbor the EGFR mutation T790M. The recent development and wide use of third-generation EGFR-TKIs targeting T790M-mutant NSCLCs have increased the importance of rebiopsy after EGFR-TKI failure. We aimed to investigate the advantages of flexible bronchoscopy as a rebiopsy method and the prevalence of and factors affecting the T790M mutation after EGFR-TKI failure. Methods: We investigated 139 patients who had undergone bronchoscopic rebiopsy and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) between Sep 2014 and Jul 2016. Results: Among the 139 patients, bronchoscopic rebiopsy yielded successful pathological diagnoses in 102 (73.4%). Among them, 41 patients with EGFR-mutant lung adenocarcinoma and EGFR-TKI progression were selected for an investigation of T790M mutation prevalence at rebiopsy. The initial EGFR mutations were exon 19 del (56.1%), L858R or L861Q (34.1%), and others (9.8%). The most common rebiopsy method was transbronchial lung biopsy (41.5%), followed by EBUS-TBNA (26.8%) and endobronchial biopsy (19.5%). The median interval to T790M emergence was the longest among cases with exon 19 deletion (14.1 months), followed by exon 21 L858R or L861Q (11.3 months) and other rare EGFR mutations (2.9 months). The T790M mutation was identified in 18 (43.9%) patients, and exon 19 del was the most significant factor affecting T790M mutation development (hazard ratio: 6.875, P = 0.014). Conclusions: Bronchoscopy was more useful than other rebiopsy approaches. The T790M emergence rate was highest in cases with exon 19 deletion, likely as a consequence of long term EGFR-TKI exposure.

Regarding Non-small Cell lung cancer there are novel therapies such as; tyrosine kinase inhibitors and immunotherapy. Currently we have two immunotherapies that can be used either as first-line treatment or second line treatment; pembrolizumab and nivolumab. A third one is being investigated as a combination of immunotherapy; ipilimumab. Aerosol treatment has been investigated for many diseases not only for the lung, but also for systematic diseases. The design of cups was found the most significant factor in producing significant effects. The comparison of cups reveals the design J as the most capable of reducing the droplets at a minimum size of mass median aerodynamic diameter (MMAD) MMAD=1.99. Drug effect comes second in sequence (F=62.04) showing that nivolumab is the most drastic preparation at low particle sizes (1.89), two drugs share an intermediate particle diameter (pembrolizumab and ipilimumab). In total drugs demonstrate a decreasing droplet size: Ipilimumab>Pembrolizumab> Nivolumab. PMID- 29581793 TI - Neonatal exposure to hyperoxia leads to persistent disturbances in pulmonary histone signatures associated with NOS3 and STAT3 in a mouse model. AB - Background: Early pulmonary oxygen exposure is one of the most important factors implicated in the development of bronchopulmonary dysplasia (BPD). Methods: Here, we analyzed short- and long-term effects of neonatal hyperoxia on NOS3 and STAT3 expression and corresponding epigenetic signatures using a hyperoxia-based mouse model of BPD. Results: Early hyperoxia exposure led to a significant increase in NOS3 (median fold change * 2.37, IQR 1.54-3.68) and STAT3 (median fold change * 2.83, IQR 2.21-3.88) mRNA levels in pulmonary endothelial cells with corresponding changes in histone modification patterns such as H2aZac and H3K9ac hyperacetylation at the respective gene loci. No complete restoration in histone signatures at these loci was observed, and responsivity to later hyperoxia was altered in mouse lungs. In vitro, histone signatures in human aortic endothelial cells (HAEC) remained altered for several weeks after an initial long-term exposure to trichostatin A. This was associated with a substantial increase in baseline eNOS (median 27.2, IQR 22.3-35.6) and STAT3alpha (median 5.8, IQR 4.8 7.3) mRNA levels with a subsequent significant reduction in eNOS expression upon exposure to hypoxia. Conclusions: Early hyperoxia induced permanent changes in histones signatures at the NOS3 and STAT3 gene locus might partly explain the altered vascular response patterns in children with BPD. PMID- 29581794 TI - Noninvasive Glioblastoma Testing: Multimodal Approach to Monitoring and Predicting Treatment Response. AB - Glioblastoma is the most aggressive adult primary brain tumor which is incurable despite intensive multimodal treatment. Inter- and intratumoral heterogeneity poses one of the biggest barriers in the diagnosis and treatment of glioblastoma, causing differences in treatment response and outcome. Noninvasive prognostic and predictive tests are highly needed to complement the current armamentarium. Noninvasive testing of glioblastoma uses multiple techniques that can capture the heterogeneity of glioblastoma. This set of diagnostic approaches comprises advanced MRI techniques, nuclear imaging, liquid biopsy, and new integrated approaches including radiogenomics and radiomics. New treatment options such as agents targeted at driver oncogenes and immunotherapy are currently being developed, but benefit for glioblastoma patients still has to be demonstrated. Understanding and unraveling tumor heterogeneity and microenvironment can help to create a treatment regime that is patient-tailored to these specific tumor characteristics. Improved noninvasive tests are crucial to this success. This review discusses multiple diagnostic approaches and their effect on predicting and monitoring treatment response in glioblastoma. PMID- 29581795 TI - The Association of Digit Ratio (2D : 4D) with Cancer: A Systematic Review and Meta-Analysis. AB - Objective: Intrauterine sex hormone environment as indicated by the second to the fourth digit ratio (2D : 4D) can be associated with cancer risk. This systematic review and meta-analysis aimed to evaluate the association of 2D : 4D with cancer diagnosis, malignancy, and age at presentation. Methods: Studies that evaluated the association of 2D : 4D with cancer risk were collected from Pubmed/MEDLINE and Clarivate Analytics databases. Nineteen studies were included in the qualitative analysis. Results: The 2D : 4D ratio was studied in prostate cancer, breast cancer, testicular cancer, gastric cancer, oral cancer, brain tumors, and cervical intraepithelial neoplasia. Low 2D : 4D was associated with prostate cancer, gastric cancer, and brain tumors, while high 2D : 4D, with breast cancer risk and cervical dysplasia. The 2D : 4D ratio was not associated with prostate, breast, and gastric cancer stage. Greater 2D : 4D ratio was associated with younger presentation of breast cancer and brain tumors. The meta-analyses demonstrated that testicular cancer was not associated with right-hand 2D : 4D ratio (p = 0.74) and gastric cancer was not associated with right-hand (p = 0.15) and left-hand (p = 0.95) 2D : 4D ratio. Conclusions: Sex hormone environment during early development is associated with cancer risk later in life. Further studies exploring the link between intrauterine hormone environment and cancer risk are encouraged. PMID- 29581796 TI - Polymorphisms in Vitamin D Receptor Genes in Association with Childhood Autism Spectrum Disorder. AB - Both genetic and environmental factors have been implicated in the etiology of autism spectrum disorder (ASD). This case-control study aimed to determine the association of single-nucleotide polymorphisms (SNPs) rs731276 (TaqI), rs1568820 (Cdx2), rs1544410 (BsmI), and rs2228570 (FokI) in the vitamin D receptor (VDR) gene with susceptibility of childhood ASD and severity of the disease. A total of 201 children with ASD and 200 healthy controls from the Han Chinese population were recruited. SNP genotyping was carried out by TaqMan probe-based real-time PCR using genomic DNA extracted from blood cells. Among four examined SNPs, only the CT genotype (odds ratio (OR) = 1.96, 95% confidence interval (CI) = 1.05 3.68, P = 0.0351) and the C allele (OR = 1.88, 95% CI = 1.02-3.46, P = 0.0416) of the rs731276 were significantly associated with increased risks of childhood ASD. None of the SNPs were associated with severity of childhood ASD. Our results reveal that certain polymorphisms in the VDR gene are a risk factor related to childhood ASD in the Han Chinese population. PMID- 29581797 TI - Exercise Therapy for Patients With Type 2 Diabetes: A Narrative Review. AB - To achieve excellent glycemic control in patients with type 2 diabetes, an adequate prescription of exercise therapy is required. The meta-analyses proposed that high-intensity training improves metabolic parameters in patients with pre diabetes or type 2 diabetes and low physical activity is associated with an increased risk of incident type 2 diabetes. Here, we would introduce literatures about effects of physical activity on mortality, cardiovascular events, and metabolic parameters, to encourage understanding of exercise therapy, and then describe how to prescribe exercise therapy for patients with type 2 diabetes. We also show the usefulness of non-exercise activity thermogenesis for diabetic patients who cannot perform volitional sporting-like exercise because of diabetic complication and/or comorbidity, by presenting results of our previous studies. PMID- 29581798 TI - The Main Anatomical Variations of the Pancreatic Duct System: Review of the Literature and Its Importance in Surgical Practice. AB - Anatomical variations or anomalies of the pancreatic ducts are important in the planning and performance of endoscopic retrograde cholangiopancreatography (ERCP) and surgical procedures of the pancreas. Normal pancreatic duct anatomy occurs in approximately 94.3% of cases, and multiple variations have been described for the remaining 5.7%. The purpose of this study was to review the literature on the pancreatic duct anatomy and to underline its importance in daily invasive endoscopic and surgical practice. Two main databases were searched for suitable articles published from 2000 to 2017, and results concerning more than 8,200 patients were included in the review. The most common anatomical variation was that of pancreas divisum, which appeared in approximately 4.5% of cases. PMID- 29581799 TI - The Impact of the Underlying Risk in Control Group and Effect Measures in Non Inferiority Trials With Time-to-Event Data: A Simulation Study. AB - Background: We designed a simulation study to assess how the conclusions of a non inferiority trial (NIT) will change if the observed risk is different from the expected risk. Methods: We simulated Weibull distribution time-to-event data with a true hazard ratio (HR) being equal or close to 1. The empirical margins and sample size of a hypothetical trial were chosen based on a systematic review. Setting the significance level at 5% for the two-sided confidence interval (CI), we examined the statistical power (i.e., the probabilities of the upper limit of the 95% CI falling within the margin) of using two measures at various underlying risk in the control group. Results: Using the empirical margins, HRs of 1.2, 1.35 or 1.5, the statistical power is lower than 0.22 when the underlying risk in the control group is less than 10%, but the power increases along with the higher underlying risk. The predicted upper limit of the 95% CI of the difference in two Kaplan-Meier estimators (DTKME) is low when risk is low (< 20%) or high (> 80%), but reaches the highest value when risk is around 50%. When the underlying risk in the control group is lower than 10%, measures of DTKME resulted in much higher power than HR. Conclusions: When HR is the effect measure, the probability of concluding non-inferiority will increase as the underlying risk in the control group increases. When DTKME is the effect measure, the probability of concluding non-inferiority will decrease as the underlying risk in the control increases. In this case, the probability of concluding non-inferiority is at a minimum when the control risk reaches about 50%. When the risk in the control arm is less than 10%, the conclusion of an NIT is sensitive to the choice of effect measure. PMID- 29581800 TI - Impact of Drug Induced Long QT Syndrome: A Systematic Review. AB - Background: Drug induced long QT syndrome is quite common in daily clinical practice but its impact is unknown. Methods: PubMed and EMBASE databases (until May 2, 2017) were searched to identify studies reporting drug induced long QT syndrome and followed the PRISMA guidelines. The main outcomes measured in these studies were QTc prolongation, ventricular arrhythmias, torsade de pointes (TdP) and death. Results: Out of 176 non-duplicate reports, 36 studies satisfied inclusion criteria and provided data on patients exposed to drugs that can potentially cause long QT. Totally, 14,756 patients were exposed and 930 patients (6.3%) were found to have QTc prolongation. The number of males was 6,400 and females were 5,723 patients. The mean age of the patients was 43.8 +/- 9.36 years. Ventricular arrhythmias were found in 379 patients (2.6%), 26 patients were found to have premature atrial contractions (PACs) and premature ventricular contractions (PVCs). TdP was found in 49 patients (0.33 %), sudden cardiac death (SCD) was found in five patients and 586 patients were found to have all-cause mortality. Conclusions: Around 6% of patients have risk of QT prolongation when exposed but only 0.3% developed TdP and 2.6% developed ventricular arrhythmias. Risk of developing arrhythmias is higher with concomitant use of multiple QT prolonging drugs. PMID- 29581801 TI - Sidestream Dark Field Imaging of the Microcirculation to Assess Preeclampsia Microvascular Dysfunction. AB - Background: Development of predictive models of preeclampsia has only yielded modest results. We hypothesized that impaired indices of microcirculatory function could be detected using sidestream dark field imaging. The objective of this study was to examine microvascular function in women at high risk for preeclampsia at mid-gestation. Methods: Women between 16 and 22 weeks of gestation were screened for eligibility. Patients were recruited if they met eligibility criteria indicating high risk for preeclampsia. Investigators performed non-invasive sidestream dark field imaging of the sublingual microcirculation. Images were analyzed to determine microcirculatory parameters (microvascular flow index, perfused vessel density, total vessel density, and proportion of perfused vessels). After delivery, charts were reviewed to determine if they developed gestational hypertension, preeclampsia or severe preeclampsia. Results: Twelve of 66 participants (18.2%) developed preeclampsia or severe preeclampsia during the course of their pregnancy. Microvascular flow index was not significantly different between participants with normal pregnancies and participants with preeclampsia or severe preeclampsia (2.75 +/- 0.38 vs. 2.80 +/- 0.34, respectively; P = 0.459). Similarly, there were no significant differences between groups in the remaining microcirculatory parameters. Conclusions: Sidestream dark field imaging of the sublingual microcirculation may remain an appropriate tool to identify women at risk for preeclampsia, albeit later in pregnancy. PMID- 29581802 TI - Fecal Calprotectin: A Comparison of Two Commercial Enzymoimmunoassays and Study of Fecal Extract Stability at Room Temperature. AB - Background: The aims of the study were: 1) to compare the fecal calprotectin (fCal) assay results with CalprolabTM ELISA (HRP) (Calpro AS) versus our routine method, EliaTM fluoroenzymoimmunoassay (Thermo Fisher), and 2) to determine whether the fCal assay results do not vary following storage of the extract at room temperature for 4 days with the Calpro AS buffer, this being the estimated shipment time from the home of the patient, and an aspect little studied to date. Methods: The fCal was determined in 198 patients divided into three groups: inflammatory bowel disease (IBD), organic intestinal disease, and functional intestinal disorders. Fecal extraction was carried out using the Roche Diagnostics kit with the corresponding specific buffers. Results: The fCal assay with the Thermo Fisher method was found to be more sensitive but less specific than with the Calpro AS technique. The positive predictive value was low (just over 50%), though the negative predictive value was high (over 90%) with both methods. The likelihood ratios revealed small but occasionally important pre- versus post-test differences. When we compared the two methods, the Spearman correlation coefficient (rho) was 0.819 (95% CI: 0.768 - 0.860) (P < 0.0001), reflecting a positive correlation. Similarly, when stratifying the fCal results into < 50 ug/g, 50 - 100 ug/g and > 100 ug/g, the resulting Cohen's kappa coefficient was 0.7766 (95% CI: 0.7025 - 0.8507), reflecting a substantial agreement between both methods. The stability of fCal was high in fecal extracts with the Calpro AS extraction buffer at room temperature for 4 days, which yielded a Spearman correlation coefficient of 0.951 (95% CI: 0.933 - 0.965), when the results were compared to those of the recent extracts (P < 0.0001). Conclusions: A positive correlation was observed between the two methods. In view of the high negative predictive value obtained with fCal, the presence of organic disease is highly unlikely in the presence of a normal concentration of this marker. We also confirmed the excellent stability of fCal in fecal extracts with the Calpro AS extraction buffer stored at room temperature. Thus, and for the sake of convenience and hygiene, it would be ideal for the patient to perform the extraction at home. PMID- 29581803 TI - Effects of a Low Advanced Glycation End Products Diet on Insulin Levels: The Feasibility of a Crossover Comparison Test. AB - Background: Advanced glycation end products (AGEs) are associated with diabetes mellitus. Digested food-derived AGEs have been implicated in the pathogenesis of AGE-related disorders, and restricting diet-derived AGEs improves insulin resistance in animal models. The AGE content in foods changes according to cooking method, and it is higher in baked or oven-fried foods than in those prepared by steaming or simmering. Here, we examined the feasibility of crossover comparison tests for determining how different cooking methods (normal diet vs. low-AGE diet) affect insulin levels in non-diabetic Japanese subjects. Methods: Five adult men and women (age, 41 +/- 7 years; body mass index (BMI), 21.7 +/- 2.6 kg/m2) were enrolled. The following dietary regimen was used: days 1 - 3, control meal; day 4, test meal (normal diet vs. low-AGE diet); day 5, washout day; and day 6, test meal. On days 4 and 6, blood samples were collected before and at 2, 4, and 6 h after meals. Results: Blood levels of N-(carboxymethyl) lysine (CML) increased with dietary intake, but the increase was similar for the normal diet and low-AGE diet groups. Mean plasma glucose, insulin, triglycerides (TG), and CML did not differ significantly between the two groups. The area under the curve (AUC) for insulin levels was lower in the low-AGE diet group (d = 0.8). The sample size calculated from the effect size of the insulin AUC change was 22. Conclusions: Twenty-two subjects may be needed to investigate the changes in clinical parameters attributable to cooking method in non-diabetic Japanese subjects. PMID- 29581804 TI - Anxiety and Depression Among Adult Patients With Diabetic Foot: Prevalence and Associated Factors. AB - Background: Diabetic foot is a frequent complication of diabetes mellitus with subsequent disturbances in the daily life of the patients. The co-existence of depression and anxiety among diabetic foot patients is a common phenomenon and the role of each of them in perpetuating the other is highlighted in the literature. Our study aimed to determine the prevalence rates of anxiety and depression, and to examine the associated risk factors among diabetic foot patients. Methods: This is a cross-sectional study. A total of 260 diabetic foot patients in the Diabetic Foot Clinic at the National Center for Diabetes, Endocrinology and Genetics (NCDEG), Amman, Jordan, participated in the study. Sociodemographic and health data were gathered through review of medical charts and a structured questionnaire. Depression and anxiety status were also assessed. The Generalized Anxiety Disorder Scale (GAD-7) was used to screen for anxiety and the Patient Health Questionnaire (PHQ-9) was used to screen for depression. A cutoff of >= 10 was used for each scale to identify those who tested positive for anxiety and depression. Results: Prevalence rate of anxiety was 37.7% and that of depression was 39.6%. Multiple logistic regression analysis showed that anxiety is positively associated with duration of diabetes of < 10 years (P = 0.01), with >= three comorbid diseases (P = 0.00), and HbA1c level of > 7% (P = 0.03). Multiple logistic regression analysis also showed that depression is positively associated with patients of < 50 years of age (P = 0.03), females (P = 0.01), current smokers (P = 0.01), patients with foot ulcer duration >= 7 months (P = 0.00), with >= three comorbid diseases (P = 0.00) than their counterparts. Conclusions: Anxiety and depression are widely prevalent among diabetic foot patients. Mental health status of those patients gets even worse among those suffering other comorbid diseases, which was a finding that requires special attention in the management of patients with diabetic foot. PMID- 29581805 TI - The Role of Urinary Neutrophil Gelatinase-Associated Lipocalin in Predicting Acute Kidney Dysfunction in Patients With Liver Cirrhosis. AB - Background: Early detection of acute kidney dysfunction (AKD) in cirrhotic patients is crucial. Urinary neutrophil gelatinase-associated lipocalin (uNGAL) has been identified as an early marker of AKD. The aim of the study was to evaluate serial uNGAL as a marker and predictor of AKD in liver cirrhosis patients. Methods: Serial uNGAL and serum creatinine (sCr) levels were measured daily during the first 6 days of admission. Furthermore, sCr levels and the estimated glomerular filtration rate (eGFR) were measured after 3 - 6 weeks. The uNGAL levels in patients with and without abnormal sCr were compared. Results: Fifty-seven consecutive cirrhotic patients were enrolled in the study. Eight of 14 patients (57%) who developed abnormal uNGAL level also had abnormal sCr level (odds ratio (OR) = 3.4, 95% CI: 0.99 - 12.03, P = 0.05). After 6 weeks, 41% of patients exhibited an abnormal uNGAL level and abnormal sCr (OR = 6.7, 95% CI: 1.55 - 28.85, P = 0.01). Area under the curve (AUROC) and the best cut-off point for highest NGAL in 6 days were 0.64 and 72.55 ng/mL, respectively. Conclusions: There is a modest association between highest uNGAL in the first 6 days of admission and sCr at week 6 in all participants. This may indicate that in cirrhotic patients, uNGAL level during the first 6 days of admission has a potential predictability for the development of high sCr and low eGFR 6 weeks later. The AUROC of 0.64 quantifies the overall ability of uNGAL to discriminate between those individuals who will have a raised sCr levels and those who will not. PMID- 29581806 TI - Accuracy of Three-Dimensional Planning in Surgery-First Orthognathic Surgery: Planning Versus Outcome. AB - Background: The benefit of computer-assisted planning in orthognathic surgery (OGS) has been extensively documented over the last decade. This study aimed to evaluate the accuracy of three-dimensional (3D) virtual planning in surgery-first OGS. Methods: Fifteen patients with skeletal class III malocclusion who underwent bimaxillary OGS with surgery-first approach were included. A composite skull model was reconstructed using data from cone-beam computed tomography and stereolithography from a scanned dental cast. Surgical procedures were simulated using Simplant O&O software, and the virtual plan was transferred to the operation room using 3D-printed splints. Differences of the 3D measurements between the virtual plan and postoperative results were evaluated, and the accuracy was reported using root mean square deviation (RMSD) and the Bland Altman method. Results: The virtual planning was successfully transferred to surgery. The overall mean linear difference was 0.88 mm (0.79 mm for the maxilla and 1 mm for the mandible), and the overall mean angular difference was 1.16 degrees . The RMSD ranged from 0.86 to 1.46 mm and 1.27 degrees to 1.45 degrees , within the acceptable clinical criteria. Conclusion: In this study, virtual surgical planning and 3D-printed surgical splints facilitated the diagnosis and treatment planning, and offered an accurate outcome in surgery-first OGS. PMID- 29581808 TI - Standardized Reporting System Use During Handoffs Reduces Patient Length of Stay in the Emergency Department. AB - Background: Emergency department (ED) shift handoffs are potential sources of delay in care. We aimed to determine the impact that using standardized reporting tool and process may have on throughput metrics for patients undergoing a transition of care at shift change. Methods: We performed a prospective, pre- and post-intervention quality improvement study from September 1 to November 30, 2015. A handoff procedure intervention, including a mandatory workshop and personnel training on a standard reporting system template, was implemented. The primary endpoint was patient length of stay (LOS). A comparative analysis of differences between patient LOS and various handoff communication methods were assessed pre- and post-intervention. Communication methods were entered a multivariable logistic regression model independently as risk factors for patient LOS. Results: The final analysis included 1,006 patients, with 327 comprising the pre-intervention and 679 comprising the post-intervention populations. Bedside rounding occurred 45% of the time without a standard reporting during pre intervention and increased to 85% of the time with the use of a standard reporting system in the post-intervention period (P < 0.001). Provider time (provider-initiated care to patient care completed) in the pre-intervention period averaged 297 min, but decreased to 265 min in the post-intervention period (P < 0.001). After adjusting for other communication methods, the use of a standard reporting system during handoff was associated with shortened ED LOS (OR = 0.60, 95% CI 0.40 - 0.90, P < 0.05). Conclusions: Standard reporting system use during emergency physician handoffs at shift change improves ED throughput efficiency and is associated with shorter ED LOS. PMID- 29581807 TI - The Prevalence and Implication of Zinc Deficiency in Patients With Chronic Liver Disease. AB - Background: Patients with liver cirrhosis often exhibit zinc deficiency. Although zinc is involved in many bioactivities, many aspects of clinical implications of zinc deficiency in liver cirrhosis remain unclear. We aimed to reveal the prevalence and implications of zinc deficiency in liver cirrhosis by assessing associations with parameters such as clinical symptoms and laboratory data. Methods: In 235 cirrhosis patients enrolled at multiple medical institutions in 2009, we assessed how blood zinc levels were associated with their clinical symptoms, patients characteristics, and liver function test results. Results: Blood zinc levels were most strongly correlated with blood albumin levels among the study parameters (r = 0.587, P < 0.0001). When blood albumin levels were <= 3.5 g/dL, blood zinc levels were < 70 MUg/dL in 88% of patients. Additionally, significant correlations were observed with age (r = -0.253, P = 0.0014), aspartate aminotransferase levels (r = -0.254, P = 0.0020), total bilirubin levels (r = -0.222, P = 0.0053), prothrombin time (r = -0.255, P = 0.0029), branched-chain amino acid to tyrosine ratio (r = 0.357, P < 0.0001), Child-Pugh score (r = 0.469, P < 0.0001), ammonia levels (r = -0.246, P = 0.0028), and total cholesterol levels (r = 0.314, P < 0.0001). Blood zinc levels were significantly lower in patients with edema/ascites (P < 0.0001), those with hepatic encephalopathy (P = 0.0215), those receiving oral diuretics (P = 0.0045), and those receiving oral branched-chain amino acids (P < 0.0001) than in those without these conditions. Conclusions: Zinc deficiency is prevalent in cirrhosis patients, whereas nitrogen metabolic disorders, particularly hypoalbuminemia, can be an indicator of zinc deficiency. Thus, cirrhosis patients exhibiting a nitrogen metabolic disorder should be examined for the presence of zinc deficiency. PMID- 29581809 TI - Autoimmune Diabetes Associated With Pembrolizumab: A Review of Published Case Reports. AB - The utility of immunotherapy, such as pembrolizumab, is becoming essential in the treatment of certain cancers. Pembrolizumab works through binding of programmed cell death 1 receptor that blocks the binding of the programmed cell death ligand 1 and is commonly used in non-small cell lung cancer and melanoma. Pembrolizumab has been reported to be associated with multiple adverse reactions such as pneumonitis, colitis, hepatitis, hypophysitis, hyperthyroidism, hypothyroidism, nephritis, and type 1 diabetes; however, pembrolizumab causing type 1 diabetes was only reported in 0.1% of the patients in clinical trials. A review of the literature generated 1,001 unique citations of which six reported cases of autoimmune diabetes associated with pembrolizumab were selected and compared. Review of the cases showed no sexual predilection and the average age of onset was 58 years old. The majority of the patients were treated for melanoma (5/6 cases), initially presented with diabetic ketoacidosis (4/6 cases), and had at one point taken ipilimumab (4/6 cases). There was no association found between the number of treatments received and the development of diabetes. With the increasing use of pembrolizumab in cancer treatment regular blood glucose monitoring during treatment, especially in patients who had also taken ipilimumab, may prevent the onset of this life-threatening complication. PMID- 29581810 TI - The Clinical Efficacy of Prostate Cancer Screening in Worldwide and Iran: Narrative Review. AB - Prostate cancer (CaP) imposes a great health burden on men, while its incidence has significantly increased in recent years. The screening program for CaP is still controversial and recent large trials have failed to present a significant reduction in prostate-specific mortality and all-cause mortality. An entire body of data obtained from worldwide studies conducted on CaP screening is required to better evaluate health policy decisions and patient decision-making. In current review, the clinical efficacy of screening programs on CaP was discussed in numerous parts of the world, such as in the US, Europe, and Asia, to provide an updated screening recommendation. Finally, we discuss about CaP screening status in Iran and update the screening recommendation in Iran. PMID- 29581811 TI - Lymphocyte to Monocyte Ratio and Modified Glasgow Prognostic Score Predict Prognosis of Lung Adenocarcinoma Without Driver Mutation. AB - Background: Neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR) and modified Glasgow prognostic score (mGPS) are useful prognostic markers based on host-related systemic inflammatory response. They have been shown as independent prognostic biomarkers in various cancers, including non-small cell lung cancer. However, there has been little evidence for a specific population of pulmonary adenocarcinoma without active epidermal growth factor receptor (EGFR) mutation. Methods: We retrospectively reviewed 159 patients who met the following criteria: histologically or cytologically diagnosed adenocarcinoma, confirmed wild-type EGFR, started first-line cytotoxic chemotherapy between July 2007 and March 2017 at our hospital, and c-stage IIIB or IV. We compared overall survival (OS) between dichotomized groups by the optimal cut-off points of NLR and LMR, and mGPS 0 - 1 vs. 2. Univariate and multivariate Cox proportional hazard analyses also detected prognostic factors for OS. Results: As favorable prognostic factors for OS, multivariate analysis detected Eastern Cooperative Oncology Group performance status (ECOG PS) 0 - 1 (hazard ratio (HR) 3.43, 95% confidence interval (CI): 2.12 - 5.53; P < 0.01), LMR >= 1.97 (HR 0.39, 95% CI: 0.21 - 0.72; P < 0.01) and mGPS 0 - 1 (HR 1.95, 95% CI: 1.20 - 3.16; P < 0.01). The OS of LMR >= 1.97 and mGPS 0 - 1 groups were significantly longer than those of LMR < 1.97 and mGPS 2 groups, respectively. We divided 159 patients into three groups, both LMR >= 1.97 and mGPS 0 - 1, either LMR >= 1.97 or mGPS 0 - 1 and both LMR < 1.97 and mGPS 2. The OS of both LMR < 1.97 and mGPS 2 was significantly shorter than the other two groups. After adjustment for age, sex, ECOG PS, sodium, alkaline phosphatase and NLR, multivariate analysis found both LMR < 1.97 and mGPS 2 as an independent poor prognostic combination in comparison with both LMR >= 1.97 and mGPS0-1 (HR 5.98, 95% CI: 2.64 - 13.5; P < 0.01). Conclusions: LMR and mGPS are independent prognostic markers for pulmonary adenocarcinoma with wild-type EGFR. Combination of LMR and mGPS can stratify patients according to prognosis.

AB - Background: The aim of the study was to evaluate the radiation sensitizing ability of ERK1/2, PI3K-AKT and JNK inhibitors in highly radiation resistant and metastatic B16F10 cells which carry wild-type Ras and Braf. Methods: Mouse melanoma cell line B16F10 was exposed to 1.0, 2.0 and 3.0 Gy of electron beam radiation. Phosphorylated ERK1/2, AKT and JNK levels were estimated by ELISA. Cells were exposed to 2.0 and 3.0 Gy of radiation with or without prior pharmacological inhibition of ERK1/2, AKT as well as JNK pathways. Cell death induced by radiation as well as upon inhibition of these pathways was measured by TUNEL assay using flow cytometry. Results: Exposure of B16F10 cells to 1.0, 2.0 and 3.0 Gy of electron beam irradiation triggered an increase in all the three phosphorylated proteins compared to sham-treated and control groups. B16F10 cells pre-treated with either ERK1/2 or AKT inhibitors equally enhanced radiation induced cell death at 2.0 as well as 3.0 Gy (P < 0.001), while inhibition of JNK pathway increased radiation-induced cell death to a lesser extent. Interestingly combined inhibition of ERK1/2 or AKT pathways did not show additional cell death compared to individual ERK1/2 or AKT inhibition. This indicates that ERK1/2 or AKT mediates radiation resistance through common downstream molecules in B16F10 cells. Conclusions: Even without activating mutations in Ras or Braf genes, ERK1/2 and AKT play a critical role in B16F10 cell survival upon radiation exposure and possibly act through common downstream effector/s. PMID- 29581813 TI - Atypical Presentation of Acute Myeloid Leukemia. AB - We present a case of a 48-year-old male who presented with worsening pleuritic chest pain for 2 h. He also complained of fever, malaise, headache and severe neck pain. Electrocardiogram (ECG) showed ST segment elevation in leads I, II, aVL and V5 with PR elevation and ST depression in aVR. On admission, troponin-I was 14.8 ng/mL. Based on ECG changes, elevated troponin and family history of early coronary artery disease, the patient was emergently taken to cardiac catheterization lab. Angiography showed non-obstructive coronaries, mild hypokinesis of mid inferior and anterolateral wall with ejection fraction (EF) of 40-45%. Based on above presentation and angiography findings, the diagnosis of acute myopericarditis was made. He was started on colchicine and ibuprofen. The other workup to determine etiology of myopericarditis was negative as shown below. Given the history of fever, headache and worsening neck pain, we also became suspicious of meningitis. Lumbar puncture was performed which was negative. On the day of admission, he was found to have blasts on complete blood count and peripheral smear. Bone marrow biopsy and flow cytometry confirmed the diagnosis of acute myeloid leukemia (AML). He received induction and salvage therapy. Repeat bone marrow confirmed complete remission and normal cytogenetics. Although pericardial or myocardial biopsies are unavailable for our patient, in the absence of other causes, it does appear that his acute myopericarditis was associated with AML. PMID- 29581814 TI - A Rare Case of Colonic Metastases From Tonsillar Carcinoma: Case Report and Review of Literature. AB - The incidence of tonsillar cancer has increased by four times in the United States over the last few decades likely due to recent increase in human papilloma virus (HPV) infections. The stage of the tumor predicts likelihood of metastasis, with advanced stages associated with higher chances of metastasis. The squamous cell carcinomas (SCCs) of the head and neck commonly metastasize to the lung, bone and liver in descending order. Tonsillar cancer rarely involves the small bowel and our review of the literature did not reveal any reported case of metastasis to the colon/large bowel. Our patient had locally metastatic tonsillar cancer, treated with partial pharyngectomy and selective neck dissection but later developed several bone and colonic metastases concurrently, likely secondary to hematogeneous dissemination after a few months of therapy. To the best of our knowledge, large bowel metastasis from head and neck SCC has never been reported in the literature. In these patients presenting with atypical gastrointestinal symptoms, a high index of suspicion should be maintained to determine the extent of metastasis and identify other metastatic sites. PMID- 29581815 TI - Inter-Rater Reliability of the Retrospectively Assigned Clinical Frailty Scale Score in a Geriatric Outreach Population. AB - Background: Frailty, a common clinical syndrome in older adults associated with increased risk of poor health outcomes, has been retrospectively calculated in previous publications; however, the reliability of retrospectively assigned frailty scores has not been established. The aim of this study was to see if frailty scores, based on chart review data, agreed with clinician-determined scores based on a comprehensive geriatric assessment. Methods: Per standard practice, all patients seen by one nurse clinician (JW) from the Southwestern Ontario Regional Geriatric Program, a tertiary care-based outreach service, between August 15, 2013 and December 31, 2015 received a comprehensive geriatric assessment which included the assignment of an interview-based Clinical Frailty Scale score (CFS-I). Subsequently, a medical student researcher (JD), blinded to the CFS-I, assigned each consenting patient a frailty score based on chart review data (CFS-C). The inter-rater reliability of the CFS-I and CFS-C was then determined. Results: Of the 41 consented patients, 39 had both a CFS-I and CFSC score. The median CFS score was 6, indicating patients were moderately frail and required assistance for some basic activities of daily living. Cohen's kappa coefficient was 0.64, indicating substantial agreement. Conclusion: CFS scores can be reliably assigned retrospectively, thereby strengthening the utility of this measure. PMID- 29581816 TI - Identifying the Priority Topics for the Assessment of Competence in Care of the Elderly. AB - Background: With Canada's senior population increasing, there is greater demand for family physicians with enhanced skills in Care of the Elderly (COE). The College of Family Physicians Canada (CFPC) has introduced Certificates of Added Competence (CACs), one being in COE. Our objective is to summarize the process used to determine the Priority Topics for the assessment of competence in COE. Methods: A modified Delphi technique was used, with online surveys and face-to face meetings. The Working Group (WG) of six physicians acted as the nominal group, and a larger group of randomly selected practitioners from across Canada acted as the Validation Group (VG). The WG, and then the VG, completed electronic write-in surveys that asked them to identify the Priority Topics. Responses were compiled, coded, and tabulated to identify the topics and to calculate the frequencies of their selection. The WG used face-to-face meetings and iterative discussion to decide on the final topic names. Results: The correlation between the initial Priority Topic list identified by the VG and that identified by the WG is 0.6793. The final list has 18 Priority Topics. Conclusion: Defining the required competencies is a first step to establishing national standards in COE. PMID- 29581817 TI - Medications & Polypharmacy Influence on Recurrent Fallers in Community: a Systematic Review. AB - The purpose of this systematic review is to summarize information about the impact different classes of medications and polypharmacy have on recurrent falls, defined as two or more falls in a 12-month period, in community-dwelling older adults. After adjustment for confounders such as age, gender, weight or depression symptoms, the reviewed studies suggested that older adults who use antidepressants, sedatives or hypnotics and anti-epileptics were more likely to experience recurrent falls than non-users. Polypharmacy (use of four or more prescription medications daily) caused 1.5-2 times higher possibility of recurrent falls in older adults. As a high-risk group, recurrent fallers require meaningful intervention. Medications are believed to be a modifiable risk factor in falls prevention; hence, special consideration should be taken to balance the benefit and harm in initiating, continuing or increasing certain classes of medications in elderly recurrent fallers. PMID- 29581818 TI - A Case for the Standardized Assessment of Testamentary Capacity. AB - Background: With an increasingly aged, frail population that holds a disproportionate amount of wealth, clinicians (especially those with expertise in older adults) may be asked with more frequency to offer a clinical opinion on testamentary capacity (TC), the mental capacity to make a will. Method: This paper reviews the legal criteria as well as the empirical research on assessment tools for determining testamentary capacity (TC). We also review the relevance of instruments used for the assessment of other decisional capacities in order to evince the potential value of developing a standardized assessment of TC for clinician experts. Results: The legal criteria, often referred to as a "test", for determining requisite TC (Banks v. Goodfellow) have remained much the same since 1870 with minimal clinical input and, as such, there has been little development in TC assessment instruments. Decisional instruments designed to assess Consent to Treatment may have relevance for TC. Conclusion: We make the case for a semi-structured interview that includes standardized criteria for the legal test for TC, supplemented by a validated brief neuropsychological assessment, which together comprise a Contemporaneous Assessment Instrument (CAI) for TC.

AB - Iron overload is a hallmark of many neurodegenerative processes such as Alzheimer's, Parkinson's, and Huntington's diseases. Unbound iron accumulated as a consequence of brain aging is highly reactive with water and oxygen and produces reactive oxygen species (ROS) or free radicals. ROS are toxic compounds able to damage cell membranes, DNA, and mitochondria. Which are the mechanisms involved in neuronal iron homeostasis and in neuronal response to iron-induced oxidative stress constitutes a cutting-edge topic in metalloneurobiology. Increasing our knowledge about the underlying mechanisms that operate in iron accumulation and their consequences would shed light on the comprehension of the molecular events that participate in the pathophysiology of the abovementioned neurodegenerative diseases. In this review, current evidences about iron accumulation in the brain, the signaling mechanisms triggered by metal overload, as well as the interaction between amyloid beta (Abeta) and iron, will be summarized.

PMID- 29581825 TI - Novel inhibitor candidates of TRPV2 prevent damage of dystrophic myocytes and ameliorate against dilated cardiomyopathy in a hamster model. AB - Transient receptor potential cation channel, subfamily V, member 2 (TRPV2) is a principal candidate for abnormal Ca2+-entry pathways, which is a potential target for therapy of muscular dystrophy and cardiomyopathy. Here, an in silico drug screening and the following cell-based screening to measure the TRPV2 activation were carried out in HEK293 cells expressing TRPV2 using lead compounds (tranilast or SKF96365) and off-patent drug stocks. We identified 4 chemical compounds containing amino-benzoyl groups and 1 compound (lumin) containing an ethylquinolinium group as candidate TRPV2 inhibitors. Three of these compounds inhibited Ca2+ entry through both mouse and human TRPV2, with IC50 of less than 10 MUM, but had no apparent effect on other members of TRP family such as TRPV1 and TRPC1. Particularly, lumin inhibited agonist-induced TRPV2 channel activity at a low dose. These compounds inhibited abnormally increased Ca2+ influx and prevented stretch-induced skeletal muscle damage in cultured myocytes from dystrophic hamsters (J2N-k). Further, they ameliorated cardiac dysfunction, and prevented disease progression in vivo in the same J2N-k hamsters developing dilated cardiomyopathy as well as muscular dystrophy. The identified compounds described here are available as experimental tools and represent potential treatments for patients with cardiomyopathy and muscular dystrophy. PMID- 29581826 TI - Increased visceral fat volume raises the risk for recurrence of hepatocellular carcinoma after curative treatment. AB - Obesity is a risk factor for the development of hepatocellular carcinoma (HCC). This study aimed to assess the influence of visceral fat on the recurrence of HCC after curative treatment. In 207 curative cases of HCC, the cross-sectional areas of visceral and subcutaneous fat mass on the computed tomographic image at the fourth lumbar vertebra were normalized by the square of the height to obtain the visceral fat mass index (VFMI) and the subcutaneous fat mass index (SFMI), respectively. Whether VFMI and SFMI contributed to recurrence of HCC and overall survival was analyzed using a Cox proportional hazards model. Increased VFMI was significantly associated with recurrence of HCC (P = 0.006), whereas SFMI was not (P = 0.502). When the patients were divided based on the optimal cut off value for VFMI (47.2 cm2/m2), obtained from maximally selected rank statistics to best predict the risk for recurrence, the higher VFMI group (n = 79) had more probability of recurrence than the lower VFMI group (n = 128) (log rank test, P = 0.002). There were significant differences in body mass index (P < .0001), SFMI (P < .0001), L3 skeletal muscle index (P < .0001), platelet count (P = 0.003), hemoglobin A1c (P < .0001), triglycerides (P = 0.004), serum leptin (P = 0.043), and underlying liver disease (P < .0001) between the groups. Neither VFMI (P = 0.689) nor SFMI (P = 0.117) significantly contributed to overall survival. VFMI, which is involved in obesity and its related metabolic disorders such as diabetes, hyperlipidemia, and adipokine imbalance, is an extremely promising indicator that can predict the risk of recurrence of HCC after curative treatment. PMID- 29581827 TI - Hypertension predicts a poor prognosis in patients with esophageal squamous cell carcinoma. AB - Background: We investigated the relationship between the preoperative hypertension and prognosis of esophageal squamous cell cancer (ESCC) patients who had underwent esophagectomy. Results: We detected 52% patients with hypertension, including 317 patients with newly diagnosed hypertension and 194 patients with history of hypertension. Compared with patients of normal blood pressure, all patients with hypertension and newly diagnosed hypertension were observed to have worse overall and ESCC-specific survival outcome (p < 0.05). After adjusted in multivariate Cox regression analysis, hypertension (HR: 1.343, 95% CI: 1.064, 1.695; HR: 1.315, 95% CI: 1.039, 1.664) and newly diagnosed hypertension (HR: 1.414, 95% CI: 1.095, 1.826; HR: 1.420, 95% CI: 1.098, 1.836) were inversely associated with overall and ESCC-specific survival outcome, respectively. While no association was found between history of hypertension and overall or ESCC specific survival outcome (HR: 1.229, 95% CI: 0.892, 1.694; HR: 1.132, 95% CI: 0.812, 1.578). Conclusions: Hypertension was an independent risk factor and resulted in inferior prognosis for ESCC patients who had underwent esophagectomy. Methods: A total of 982 ESCC patients who had underwent esophagectomy from August 2010 to December 2015 were enrolled in our study with a follow up of 6 years. The Kaplan-Meier method and log-rank test were respectively used to calculate and compare survival rate, and Cox proportional hazards regression model was applied to identify independent prognostic factors. PMID- 29581828 TI - Genetic variation of CXCR4 and risk of coronary artery disease: epidemiological study and functional validation of CRISPR/Cas9 system. AB - Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, while coronary artery disease (CAD) account for a large part of CVDs. Vascular CXCR4 could limit atherosclerosis by maintaining arterial integrity. Here, we conducted a population-based, case-control study to evaluate the associations of common genetic variation within the CXCR4 gene (rs2228014, rs117600832, rs2471859, and rs2322864) with CAD risk in a Chinese population. We found that CXCR4 rs2228014 was significantly associated with 1.29-fold increased risk of CAD (A vs G: OR = 1.29; 95% CI = 1.07-1.55; P = 0.007). The subjects with genotype AA (OR = 1.98; 95% CI = 1.03-3.81; P = 0.041) and AG (OR = 1.27; 95% CI = 1.02-1.58; P = 0.030) have higher risk of CAD, compared with those with genotype GG. Furthermore, both in the CAD patients with diabetes and those without diabetes, rs2228014 was significantly associated with increased risk of CAD (P < 0.05). Additionally, we also validated the significant association for rs2322864 (C vs T: OR = 1.20; 95% CI = 1.00-1.44; P = 0.046). Knockout of CXCR4 gene could significantly impair the capacity of cholesterol efflux (P < 0.01). These findings strongly suggest that CXCR4 polymorphisms might contribute to CAD susceptibility, and the exact biological mechanism awaits further research. PMID- 29581829 TI - Cystatin A suppresses tumor cell growth through inhibiting epithelial to mesenchymal transition in human lung cancer. AB - Cystatin A (CSTA), belonging to type 1 cystatin super-family, is expressed primarily in epithelial and lymphoid tissues for protecting cells from proteolysis of cytoplasmic and cytoskeletal proteins by cathepsins B, H and L. CSTA acts as a tumor suppressor in esophageal cancer, however, its role in lung cancer has not yet been elucidated. Here we found that CSTA was down-regulated in all lung cancer cell lines compared to normal lung epithelial cells. CSTA was restored in most lung cancer cell lines after treatment with demethylation agent 5-aza-2-deoxycytidine and deacetylation agent Trichostatin. Bisulfite sequencing revealed that CSTA was partially methylated in the promoter and exon 1. In primary lung tumors, squamous cell carcinoma (SCC) significantly expressed more CSTA compared to adenocarcinoma (p<0.00001), and higher expression of CSTA was significantly associated with lower tumor grade (p<0.01). CSTA stable transfection reduced the activity of cathepsin B and inhibited the ability of colony formation, migration and invasion, and enhanced gemcitabine-induced apoptosis. CSTA overexpression resulted in reduced activity of ERK, p-38, and AKT. Additionally, CSTA overexpression led to a mesenchymal to epithelial transition (MET) and prevented the TGF-beta1-induced epithelial to mesenchymal transition (EMT) through inhibiting the ERK/MAPK pathway. In conclusion, our date indicate 1) epigenetic regulation is associated with CSTA gene silencing; 2) CSTA exerts tumor suppressive function through inhibiting MAPK and AKT pathways; 3) Overexpression of CSTA leads to MET and prevents TGF-beta1-induced EMT by modulating the MAPK pathway; 4) CSTA may be a potential biomarker for lung SCC and tumor differentiation. PMID- 29581830 TI - Orthotopic hepatic cancer: radiofrequency hyperthermia-enhanced intratumoral herpes simplex virus-thymidine kinase gene therapy. AB - Purpose: To validate the feasibility of using interventional radiofrequency hyperthermia(RFH) to enhance herpes simplex virus-thymidine kinase (HSV TK)/ganciclovir (GCV) gene therapy of rat orthotopic hepatic cancer. Material and Methods: Rat hepatocellular carcinoma cells (MCA-RH-7777) were transduced with lentivirus/luciferase gene for optical imaging. In-vitro experiments with the luciferase cells and in-vivo experiments on rats with orthotopic hepatic tumors were divided into four treatment groups: (i) HSV-TK/GCV-mediated gene therapy combined with RFH; (ii) gene therapy alone; (iii) RFH alone; and (iv) phosphate buffered saline (PBS). Cell viability was evaluated by MTS assay and confocal microscopy, and HSV-TK gene expression in cells and tumors was quantified by western blotting. Bioluminescent optical imaging and ultrasound imaging were used to monitor and compare the photon signal and tumor size changes among different treatment groups overtime, respectively. The imaging findings were correlated with histology. Results: For in-vitro experiments, the combination therapy group (gene therapy + RFH) demonstrated the lowest cell proliferation by MTS assay, compared to the gene therapy alone, RFH alone, and PBS (26.1+/-3.2% vs 50.4+/ 4.6% vs 82.9+/-6.3% vs 100%, p<0.01). The combination therapy group also showed fewer survived cells by the confocal microscopy and the lowest bioluminescent signal by the optical imaging. For in-vivo experiments, the combination therapy group demonstrated a significantly decreased signal intensity on the bioluminescent optical imaging (0.57+/-0.09, 1.06+/-0.10 vs 3.43+/-0.27 vs 3.85+/ 0.12, p<0.05) and smallest tumor volume by ultrasound imaging (0.28+/-0.11 vs 1.28+/-0.23vs 4.64+/-0.35 vs 6.37+/-0.36, p<0.05), compared to the other three groups. Additionally, these imaging findings correlated well with the histological confirmation. Conclusion: It is feasible to use RFH to enhance HSV TK/GCV gene therapy of hepatic tumors in in-vitro and in-vivo settings, as assessed by molecular imaging. This technical development may provide a novel opportunity for effective treatment of liver malignancies by employing simultaneous integration of radiofrequency technology, interventional oncology, and direct intratumoral gene therapy. PMID- 29581831 TI - Association analysis of SNPs present in plasma with adverse events and population pharmacokinetics in Chinese sunitinib treated patients with renal cell carcinoma. AB - Background: Sunitinib is a tyrosine kinase inhibitor with effective therapeutic outcomes in patients with renal-cell carcinoma. The study were to analyze the association of single-nucleotide polymorphisms present in cell-free DNA and pharmacokinetics with sunitinib treatment-emergent adverse events in Chinese patients with renal-cell carcinoma. Materials and Methods: We genotyped 8 keys SNPs in 6 candidate genes. The plasma concentrations of sunitinib and N-desethyl sunitinib were measured using a high performance liquid chromatography-tandam mass spectrometry method. Correlations between the single-nucleotide polymorphisms and adverse events were investigated by univariate and multivariate logistic regression and we quantitatively evaluated the effect of single nucleotide polymorphisms on the pharmacokinetics of sunitinib by using a population PK model. Results: Necessary dose reductions of sunitinib were significantly correlated with SNP rs1933437 in FLT3. A higher severity of AEs were collected with SNP rs2032582 in ABCB1 and rs1800812 in PDGFRalpha. Thrombocytopenia was collected with rs1800812 in PDGFRalpha. Our study provides a population PK model of sunitinib with the ABCB1 genotype as a predictive covariate for apparent oral clearance. Conclusions: Our study preliminarily confirmed the hypothesis that the pharmacokinetics of sunitinib is affected by the SNPs of enzyme in Chinese renal-cell carcinoma patients, and this affects the different distribution and severity of adverse events of sunitinib. PMID- 29581832 TI - AP-1 confers resistance to anti-cancer therapy by activating XIAP. AB - The underlying cause of treatment failure in many cancer patients is intrinsic and acquired resistance to chemotherapy. Recently, histone deacetylase (HDAC) inhibitors have developed into a promising cancer treatment. However, resistance mechanism induced by HDAC inhibitors remains largely unknown. Here we report that a HDAC inhibitor, JNJ-2648158 induced transcription of XIAP by activating AP-1 expression, which conferring resistance to chemotherapeutics. Our results showed that high expression of c-Fos caused by HDAC inhibitor promoted AP-1 formation during acquired resistance towards chemo-drugs, indicating an extremely poor clinical outcome in breast cancers and liver cancers. Our study reveals a novel regulatory mechanism towards chemo-drug resistance, and suggests that XIAP may serve as a potential therapeutic target in those chemo-resistant cancer cells. PMID- 29581833 TI - Perspectives of patients and physicians about neuroendocrine tumors. A qualitative study. AB - Purpose: Gastrointestinal neuroendocrine tumors (NETs) are rare, complex to manage, and often have a chronic course. Qualitative methods are a tool of choice for focusing on patients' and physicians' points of view especially when dealing with a complex and rare disease. Nonetheless, they remain undeveloped in research related to NETs. This study aimed to explore the experience of NETs among both patients and their physicians and to cross their perspectives for the purpose of finding pathways to improving care. Results: Our analysis found two themes: (1) the questions raised by this disease, and (2) the complex experience of this singular disease. Our findings underlined the experience of confusion found among patients regarding the patient's unusual somatic experience and around the question of vocabulary, i.e. the naming of the disease and the semantic field of severity in the medical discourse. Conclusion: Means for reducing the confusion that patients experience in this disease are needed. The explanations that the physician offers to the patient must clarify the issues related to NETs. We therefore propose a statement that all physicians can use to support patients diagnosed with neuroendocrine tumors to clear up potential confusion. Methods: We conducted a qualitative study, based on 40 semi-structured interviews, in a specialized department of gastro-pancreatology. Participants, purposively selected until data saturation, came from two different sub-samples: (i) patients with a metastatic NETs (N = 20) and (ii) their referring physicians (N = 10). The data were examined by thematic analysis. PMID- 29581834 TI - Synergistic effects of inhibiting the MNK-eIF4E and PI3K/AKT/ mTOR pathways on cell migration in MDA-MB-231 cells. AB - The study of eukaryotic initiation factor 4E (eIF4E) is a key focus in cancer research due to its role in controlling the translation of tumour-associated proteins, that drive an aggressive migratory phenotype. eIF4E is a limiting component of the eIF4F complex which is a critical determinant for the translation of mRNAs. Mitogen-activated protein kinase interacting protein kinases (MNK1/2) phosphorylate eIF4E on Ser209, promoting the expression of oncogenic proteins, whereas mTORC1 phosphorylates and de-activates the eIF4E inhibitor, 4E-BP1, to release translational repression. Here we show that inhibiting these pathways simultaneously effectively slows the rate of cell migration in breast cancer cells. However, a molecular hybridisation approach using novel, cleavable dual MNK1/2 and PI3K/mTOR inhibiting hybrid agents was less effective at slowing cell migration. PMID- 29581835 TI - Cell internalization of 7-ketocholesterol-containing nanoemulsion through LDL receptor reduces melanoma growth in vitro and in vivo: a preliminary report. AB - Oxysterols are cholesterol oxygenated derivatives which possess several biological actions. Among oxysterols, 7-ketocholesterol (7KC) is known to induce cell death. Here, we hypothesized that 7KC cytotoxicity could be applied in cancer therapeutics. 7KC was incorporated into a lipid core nanoemulsion. As a cellular model the murine melanoma cell line B16F10 was used. The nanoparticle (7KCLDE) uptake into tumor cells was displaced by increasing amounts of low density-lipoproteins (LDL) suggesting a LDL-receptor-mediated cell internalization. 7KCLDE was mainly cytostatic, which led to an accumulation of polyploid cells. Nevertheless, a single dose of 7KCLDE killed roughly 10% of melanoma cells. In addition, it was observed dissipation of the transmembrane potential, evidenced with flow cytometry; presence of autophagic vacuoles, visualized and quantified with flow cytometry and acridine orange; and presence of myelin figures, observed with ultrastructural microscopy. 7KCLDE impaired cytokenesis was accompanied by changes in cellular morphology into a fibroblastoid shape which is supported by cytoskeletal rearrangements, as shown by the increased actin polymerization. 7KCLDE was injected into B16 melanoma tumor-bearing mice. 7KCLDE accumulated in the liver and tumor. In melanoma tumor 7KCLDE promoted a >50% size reduction, enlarged the necrotic area, and reduced intratumoral vasculature. 7KCLDE increased the survival rates of animals, without hematologic or liver toxicity. Although more pre-clinical studies should be performed, our preliminary results suggested that 7KCLDE is a promising novel preparation for cancer chemotherapy. PMID- 29581836 TI - RUNX1 and RUNX3 protect against YAP-mediated EMT, stem-ness and shorter survival outcomes in breast cancer. AB - Hippo pathway target, YAP has emerged as an important player in solid tumor progression. Here, we identify RUNX1 and RUNX3 as novel negative regulators of oncogenic function of YAP in the context of breast cancer. RUNX proteins are one of the first transcription factors identified to interact with YAP. RUNX1 or RUNX3 expression abrogates YAP-mediated pro-tumorigenic properties of mammary epithelial cell lines in an interaction dependent manner. RUNX1 and RUNX3 inhibit YAP-mediated migration and stem-ness properties of mammary epithelial cell lines by co-regulating YAP-mediated gene expression. Analysis of whole genome expression profiles of breast cancer samples revealed significant co-relation between YAP-RUNX1/RUNX3 expression levels and survival outcomes of breast cancer patients. High RUNX1/RUNX3 expression proved protective towards YAP-dependent patient survival outcomes. High YAP in breast cancer patients' expression profiles co-related with EMT and stem-ness gene signature enrichment. High RUNX1/RUNX3 expression along with high YAP reflected lower enrichment of EMT and stem-ness signatures. This antagonistic activity of RUNX1 and RUNX3 towards oncogenic function of YAP identified in mammary epithelial cells as well as in breast cancer expression profiles gives a novel mechanistic insight into oncogene tumor suppressor interplay in the context of breast cancer progression. The novel interplay between YAP, RUNX1 and RUNX3 and its significance in breast cancer progression can serve as a prognostic tool to predict cancer recurrence. PMID- 29581837 TI - Molecular and clinical features of the TP53 signature gene expression profile in early-stage breast cancer. AB - Purpose: TP53 signature has a robust predictive performance for prognosis in early-stage breast cancer, but the experiment that reported this relied on public microarray data and fresh-frozen samples. Before TP53 signature can be used in a clinical setting, a simple and low-cost diagnostic system using formalin-fixed paraffin-embedded (FFPE) samples is needed. New treatments based on the biological characteristics of TP53 signature are expected to follow. Experimental Design: TP53 signature was evaluated in 174 FFPE early breast cancer specimens using digital quantification via the nCounter technique (NanoString). Patients were classified as TP53 signature mutant type (n = 64) or wild type (n = 110). Predictive power of TP53 signature was compared with those of other gene expression signatures in 153 fresh-frozen samples of the same cohort by RNA-seq. The molecular features of TP53 signature were elucidated using TCGA omics data and RNA-seq data to explore new therapeutic strategies for patients with TP53 signature mutant type. Results: TP53 signature was a strong predictor of prognosis and was also more accurate than other gene expression signatures and independent of other clinicopathological factors. TCGA data analysis showed that risk score of TP53 signature was an index of chromosomal and genomic instability and that TP53 signature mutant type was associated with higher PD-L1 expression, variation in copy numbers, and numbers of somatic mutations. Conclusions: TP53 signature as diagnosed using the nCounter system is not only a robust predictor of prognosis but also a potential predictor of responsiveness to immune checkpoint inhibitors. PMID- 29581838 TI - High expression of SLCO2B1 is associated with prostate cancer recurrence after radical prostatectomy. AB - Solute carrier organic anion (SLCO) gene families encode organic anion transport proteins, which are transporters that up-take a number of substrates including androgens. Among them, high expression of SLCO2B1 is known to associate with the resistance to androgen deprivation therapy in prostate cancer (PCa). We hypothesized that high expression of SLCO genes enhances PCa progression by promoting the influx of androgen. Here, we demonstrated the impact of the expression levels of SLCO2B1 on prognosis in localized PCa after radical prostatectomy (RP) utilizing 494 PCa cases in The Cancer Genome Atlas (TCGA). SLCO2B1 high expression group showed significantly worse Disease-free survival (DFS) after RP (p = 0.001). The expression level of SLCO2B1 was significantly higher in advanced characteristics including Gleason Score (GS <= 6 vs GS = 7; p = 0.047, GS = 7 vs GS >= 8; p = 0.002), pathological primary tumor (pT2 vs pT3/4; p < 0.001), and surgical margin status (positive vs negative; p = 0.013), respectively. There was a significant difference in DFS between these two groups only in GS >= 8 patients (p = 0.006). Multivariate analysis demonstrated that only SLCO2B1 expression level was an independent predictor for DFS after RP in GS >= 8. SLCO2B1 high expressed tumors in GS >= 8 not only enriched epithelial mesenchymal transition (EMT) related gene set, (p = 0.027), as well as Hedgehog (p < 0.001), IL-6/JAK/STAT3 (p < 0.001), and K-ras signaling gene sets (p < 0.001), which are known to promote EMT, but also showed higher expression of EMT related genes, including N-cadherin (p = 0.024), SNAIL (p = 0.001), SLUG (p = 0.001), ZEB-1 (p < 0.001) and Vimentin (p < 0.001). In conclusion, PCa with high expression of SLCO2B1 demonstrated worse DFS, which might be due to accelerated EMT. PMID- 29581839 TI - Excellent outcomes of 2G-TKI therapy after imatinib failure in chronic phase CML patients. AB - Second-generation tyrosine kinase inhibitors (2G-TKIs) dasatinib and nilotinib produced historical rates of about 50% complete cytogenetic response (CCyR) and about 40% major molecular response (MMR) in chronic myeloid leukaemia (CML) patients failing imatinib. Direct comparisons between dasatinib and nilotinib are lacking, and few studies addressed the dynamics of deep molecular response (DMR) in a "real-life" setting. We retrospectively analyzed 163 patients receiving dasatinib (n = 95) or nilotinib (n = 68) as second-line therapy after imatinib. The two cohorts were comparable for disease's characteristics, although there was a higher rate of dasatinib use in imatinib-resistant and of nilotinib in intolerant patients. Overall, 75% patients not in CCyR and 60% patients not in MMR at 2G-TKI start attained this response. DMR was achieved by 61 patients (37.4%), with estimated rate of stable DMR at 5 years of 24%. After a median follow-up of 48 months, 60% of patients persisted on their second-line treatment. Rates and kinetics of cytogenetic and molecular responses, progression-free and overall survival were similar for dasatinib and nilotinib. In a "real-life" setting, dasatinib and nilotinib resulted equally effective and safe after imatinib failure, determining high rates of CCyR and MMR, and a significant chance of stable DMR, a prerequisite for treatment discontinuation. PMID- 29581840 TI - Interferon beta induces apoptosis in nasopharyngeal carcinoma cells via the TRAIL signaling pathway. AB - The combination of neoadjuvant chemotherapy, radiochemotherapy, and maintenance therapy with interferon beta (IFNbeta) has led to superior results in the treatment of children and adolescents with nasopharyngeal carcinoma (NPC). However, nothing is known about the mechanism of the antitumor activity of IFNbeta in NPC. Here, we investigate the role of IFNbeta on apoptosis in NPC cells. Six NPC cell lines, one patient-derived NPC xenograft (PDX) and one SV40 transformed nasoepithelial cell line were used. Induction of apoptosis by IFNbeta was measured by flow cytometric analysis of subG1-DNA-content, Hoechst 33258 staining and activation of caspase-3. Dissection of death ligand signaling pathways included measuring surface expression of its components by flow cytometry, activation by death ligands and neutralization with specific antibodies and siRNA. IFNbeta induced apoptosis at concentrations achievable in humans in five of six NPC cell lines and in PDX cells but not in nasoepithelial cells. Inhibition of caspases-3 and -8 abrogated this effect suggesting IFNbeta promoted apoptosis through the extrinsic pathway. IFNbeta induced surface expression of TRAIL and TRAIL-R2 and the addition of an anti-TRAIL-antibody or transfection with TRAIL-siRNA blocked IFNbeta-induced apoptosis. No induction of TRAIL-expression was noted in the IFNbeta-resistant cell line. In conclusion, IFNbeta leads to apoptosis in NPC cells in an autocrine way via the induction of TRAIL expression and subsequent activation of the TRAIL-signaling pathway. The mechanism described could at least partly explain the clinical benefit of IFNbeta in the treatment of NPC. Further studies in a mouse-xenograft model are warranted to substantiate this effect in vivo. PMID- 29581841 TI - Dysregulation of fibulin-5 and matrix metalloproteases in epithelial ovarian cancer. AB - Fibulin 5 (FBLN5) is an extracellular matrix glycoprotein that suppresses matrix metalloprotease 9 (MMP-9), angiogenesis and epithelial cell motility. Here, we investigated the regulation and function of FBLN5 in epithelial ovarian cancer (EOC). FBLN5 mRNA was down-regulated 5-fold in EOC relative to benign ovary. Not surprisingly, MMP9 mRNA and enzyme activity were increased significantly, and inversely correlated with FBLN5 gene expression. FBLN5 degradation products of 52.8 and 41.3 kDa were increased substantially in EOC. We identified two candidate proteases (serine elastase and MMP-7, but not MMP-9) that cleave FBLN5. MMP-7, but not neutrophil elastase, gene expression was increased dramatically in EOC. Recombinant FBLN5 significantly inhibited adhesion of EOC cells to both laminin and collagen I. Finally, using immunohistochemistry, we found immunoreactive FBLN5 within tumor macrophages throughout human EOC tumors. This work indicates that FBLN5 is degraded in EOC most likely by proteases enriched in macrophages of the tumor microenvironment. Proteolysis of FBLN5 serves as a mechanism to promote cell adhesion and local metastasis of ovarian cancer cells. Promotion of a stable ECM with intact FBLN5 in the tumor matrix may serve as a novel therapeutic adjunct to prevent spread of ovarian cancer. PMID- 29581842 TI - Integrative proteomic and transcriptomic analysis provides evidence for TrkB (NTRK2) as a therapeutic target in combination with tyrosine kinase inhibitors for non-small cell lung cancer. AB - While several molecular targets have been identified for adenocarcinoma (ACA) of the lung, similar drivers with squamous cell carcinoma (SCC) are sparse. We compared signaling pathways and potential therapeutic targets in lung SCC and ACA tumors using reverse phase proteomic arrays (RPPA) from two independent cohorts of resected early stage NSCLC patients: a testing set using an MDACC cohort (N=140) and a validation set using the Cancer Genome Atlas (TCGA) cohorts. We identified multiple potentially targetable proteins upregulated in SCC, including NRF2, Keap1, PARP, TrkB, and Chk2. Of these potential targets, we found that TrkB also had significant increases in gene expression in SCC as compared to adenocarcinoma. Thus, we next validated the upregulation of TrkB both in vitro and in vivo and found that it was constitutively expressed at high levels in a subset of SCC cell lines. Furthermore, we found that TrkB inhibition suppressed tumor growth, invasiveness and sensitized SCC cells to tyrosine kinase EGFR inhibition in a cell-specific manner. PMID- 29581843 TI - Comparative study of interhemispheric functional connectivity in left eye monocular blindness versus right eye monocular blindness: a resting-state functional MRI study. AB - Objective: In the present study, we investigated the brain interhemispheric functional connectivity changes in left eye MB versus right eye MB patients by voxel-mirrored homotopic connectivity (VMHC) methods. Methods: A total of 31 patients with MB (15 with left eye MB and 16 with right eye MB), and 31 healthy controls (HCs) closely matched for age were recruited. All subjects underwent functional magnetic resonance imaging (fMRI) examinations. The VMHC method was used to evaluate directly functional interactions between the hemispheres. A one way ANOVA was performed to determine the regions in which the VMHC differs between the three groups. Patients with MB were distinguished from HCs by a receiver operating characteristic (ROC) curve. The relationships between the mean VMHC signal values in many brain regions and clinical features in MB patients were calculated by pearson correlation analysis. Results: Compared with HCs, MB patients had significantly decreased VMHC values in the cuneus/calcarine/lingual gyrus. Furthermore, left eye MB showed decreased VMHC values in the cuneus/calcarine/lingual gyrus and showed increased VMHC values in the insula and middle frontal gyrus compared with HC. In addition, right eye MB showed decreased VMHC values in the cuneus/calcarine/lingual gyrus, primary motor cortex (M1)/primary somatosensory cortex (S1) and superior parietal lobule. Conclusion: MB subjects showed abnormal brain interhemispheric functional connectivity in visual pathways. Furthermore, different patterns of brain interhemispheric functional connectivity occurred in the left eye and right eye MB. These VMHC values provide much useful information to explain the neural mechanism changes in MB. PMID- 29581844 TI - Predictive value of inflammation-based prognostic scores in patients with metastatic renal cell carcinoma treated with cytoreductive nephrectomy. AB - Inflammation-based prognostic scores are useful for predicting survival in various cancers. Here, we aimed to determine the most useful inflammation-based prognostic score for predicting survival in patients with metastatic renal cell carcinoma undergoing cytoreductive nephrectomy. We retrospectively analyzed the data of 152 patients who underwent cytoreductive nephrectomy for metastatic renal cell carcinoma between 1986 and 2015. In the multivariate stepwise analysis, the combination of age, Memorial Sloan-Kettering Cancer Center score, histology, sarcomatoid change, clinical nodal stage, brain metastasis, and liver metastasis was a significant predictor for survival (Harrell's concordance index [c-index]: 0.638). The c-index of the combination improved with the addition of an inflammation-based prognostic score: C-reactive protein (c-index: 0.672), Glasgow prognostic score (c-index: 0.674), neutrophil-to-lymphocyte ratio (c-index: 0.685), lymphocyte-to-monocyte ratio (c-index: 0.670), platelet-to-lymphocyte ratio (c-index: 0.666), systemic inflammation response index (c-index: 0.652), and systemic immune-inflammation index (c-index: 0.678). The neutrophil-to lymphocyte ratio provided the greatest improvement in the c-index. Additional multivariate analysis showed that the neutrophil-to-lymphocyte ratio was an independent prognostic factor for survival (P < 0.0001). The neutrophil-to lymphocyte ratio was the most useful inflammation-based prognostic score for predicting survival in patients with metastatic renal cell carcinoma treated with cytoreductive nephrectomy. PMID- 29581845 TI - TP53 mutations and number of alterations correlate with maximum standardized uptake value (SUVmax) determined by positron emission tomography/computed tomography (PET/CT) [18F] fluorodeoxyglucose (18F-FDG PET). AB - Background: Our study explored the relationship between the molecular changes in cancer and the maximum standardized uptake value (SUVmax) determined by positron emission tomography/computed tomography (PET/CT) with [18F] fluorodeoxyglucose (18F-FDG). Results: A higher SUVmax correlated with TP53 alterations, but not with histologic diagnosis or other gene/pathway mutations or copy number alterations. In data from breast, lung and colon cancer, patients with the highest SUVmax show more genomic anomalies compared to those with the lowest SUVmax (P < 0.005). Conclusions: A higher SUVmax on 18F-FDG PET/CT is associated with TP53 tumor suppressor gene anomalies and the presence of more genomic anomalies. Since TP53 alterations and high SUVmax both correlate with a poor prognosis, the underlying mechanism/implications of this association merit further study. Methods: Overall, 176 patients with diverse cancers had a tumor biopsy within 6 months after a PET/CT image for SUVmax measurement. The biopsy was interrogated by next generation sequencing (182 to 315 genes). TP53, EGFR, ALK, MYC, MET and FGF/FGFR genes and DNA repair, PI3K/Akt/mTOR (PAM), MEK, CYCLIN, and WNT pathway genes were analyzed. PMID- 29581846 TI - Preclinical characterization of therapeutic antibodies targeted at the carboxy terminus of Sonic hedgehog. AB - The Sonic Hedgehog (Shh) signaling pathway has been implicated in the development and tumor progression of a number of human cancers. Using synthetic peptide mimics to mount an immune response, we generated a mouse mAb to the carboxy (C) terminus of the Shh protein and characterized its preclinical antitumor effects. In vitro screening guided selection of the best candidate for mAb scale-up production and therapeutic development. C-term anti-Shh, Ab 1C11-2G4 was selected based on ELISA screens, Western blotting, and flow cytometric analyses. Purified Ab 1C11-2G4 was shown to recognize and bind both Shh peptide mimics and cell surface Shh. Administration of Ab 1C11-2G4 not only reduced cell viability in 7 cancer cell lines but also significantly inhibitted tumor growth in a xenograft model of A549 lung cancer cells. Ex vivo analyses of xenograft tumors revealed a reduction in Shh signal transduction and apoptosis in 2G4-treated mice. Collectively, our results provide early demonstration of the antitumor utility of antibodies specific for the C-terminal region of Shh, and support continued development to evaluate their potential efficacy in cancers in which Shh activity is elevated. PMID- 29581847 TI - Mandatory role of HMGA1 in human airway epithelial normal differentiation and post-injury regeneration. AB - Due to high levels of expression in aggressive tumors, high mobility group AT hook 1 (HMGA1) has recently attracted attention as a potential anti-tumor target. However, HMGA1 is also expressed in normal somatic progenitor cells, raising the question: how might systemic anti-HMGA1 therapies affect the structure and function of normal tissue differentiation? In the present study, RNA sequencing data demonstrated HMGA1 is highly expressed in human airway basal stem/progenitor cells (BC), but decreases with BC differentiation in air-liquid interface cultures (ALI). BC collected from nonsmokers, healthy smokers, and smokers with chronic obstructive pulmonary disease (COPD) displayed a range of HMGA1 expression levels. Low initial expression levels of HMGA1 in BC were associated with decreased ability to maintain a differentiated ALI epithelium. HMGA1 down regulation in BC diminished BC proliferation, suppressed gene expression related to normal proliferation and differentiation, decreased airway epithelial resistance, suppressed junctional and cell polarity gene expression, and delayed wound closure of airway epithelium following injury. Furthermore, silencing of HMGA1 in airway BC in ALI increased the expression of genes associated with airway remodeling in COPD including squamous, epithelial-mesenchymal transition (EMT), and inflammatory genes. Together, the data suggests HMGA1 plays a central role in normal airway differentiation, and thus caution should be used to monitor airway epithelial structure and function in the context of systemic HMGA1 targeted therapies. PMID- 29581848 TI - Aberrant expression of NKL homeobox gene HLX in Hodgkin lymphoma. AB - NKL homeobox genes are basic regulators of cell and tissue differentiation, many acting as oncogenes in T-cell leukemia. Recently, we described an hematopoietic NKL-code comprising six particular NKL homeobox genes expressed in hematopoietic stem cells and lymphoid progenitors, unmasking their physiological roles in the development of these cell types. Hodgkin lymphoma (HL) is a B-cell malignancy showing aberrant activity of several developmental genes resulting in disturbed B cell differentiation. To examine potential concordances in abnormal lymphoid differentiation of T- and B-cell malignancies we analyzed the expression of the hematopoietic NKL-code associated genes in HL, comprising HHEX, HLX, MSX1, NKX2 3, NKX3-1 and NKX6-3. Our approach revealed aberrant HLX activity in 8 % of classical HL patients and additionally in HL cell line L-540. Accordingly, to identify upstream regulators and downstream target genes of HLX we used L-540 cells as a model and performed chromosome and genome analyses, comparative expression profiling and functional assays via knockdown and overexpression experiments therein. These investigations excluded chromosomal rearrangements of the HLX locus at 1q41 and demonstrated that STAT3 operated directly as transcriptional activator of the HLX gene. Moreover, subcellular analyses showed highly enriched STAT3 protein in the nucleus of L-540 cells which underwent cytoplasmic translocation by repressing deacetylation. Finally, HLX inhibited transcription of B-cell differentiation factors MSX1, BCL11A and SPIB and of pro apoptotic factor BCL2L11/BIM, thereby suppressing Etoposide-induced cell death. Collectively, we propose that aberrantly expressed NKL homeobox gene HLX is part of a pathological gene network in HL, driving deregulated B-cell differentiation and survival. PMID- 29581849 TI - Urinary cell-free nucleic acid IQGAP3: a new non-invasive diagnostic marker for bladder cancer. AB - Background: There is growing interest in developing new non-invasive diagnostic tools for bladder cancer (BC) that have better sensitivity and specificity than cystoscopy and cytology. This study examined the value of urinary cell-free nucleic acid (NA) as a diagnostic marker for BC. Material and methods: A total of 81 patients (74 BC and 7 normal controls) were used for a tissue set, and 212 patients (92 BC and 120 normal controls) were used as a urine set. Expression of tissue mRNA and urinary cell-free NAs was then examined. Results: Four candidate genes were top-ranked in the tissue microarray. Expression levels of two of these (IQGAP3 and TOP2A) in BC tissue and urine samples from BC patients were significantly higher than those in samples from the control groups. Binary logistic regression analysis of cell-free NA levels in urine samples revealed that IQGAP3 was significantly associated with BC: PicoGreen-adjusted odds ratio (OR), 3.434; confidence interval (CI), 2.999-4.180; P<0.001; RiboGreen-adjusted OR, 2.242; CI, 1.793-2.840; P<0.001. Further analysis of IQGAP3 urinary cell-free NAs with respect to tumor invasiveness and grade also yielded a high AUC, suggesting that IQGAP3 can discriminate between BC patients and non-cancer patients with hematuria. Conclusions: Levels of IQGAP3 urinary cell-free NA in BC patients were significantly higher than those in normal controls or patients with hematuria. High levels of IQGAP3 urinary cell-free NA also reflected high expression in BC tissues. Therefore, IQGAP3 urinary cell-free NA may be a complementary diagnostic biomarker for BC. PMID- 29581850 TI - Interactome analysis of transforming growth factor-beta-activated kinase 1 in Helicobacter pylori-infected cells revealed novel regulators tripartite motif 28 and CDC37. AB - Transforming growth factor-beta (TGFbeta)-activated kinase 1 (TAK1) plays a central role in controlling the cellular pro-inflammatory response via the activation of the nuclear factor kappaB (NF-kappaB)- and mitogen-activated protein (MAP) kinases-dependent transcriptional programs. Here, we show that depletion of TAK1 and the TAK1-binding proteins TAB1 and TAB2 affects NF-kappaB, JNK and p38 phosphorylation and suppresses NF-kappaB activity in AGS cells infected with Helicobacter pylori or stimulated with the cytokines TNF and IL 1beta. To increase our understanding of TAK1 regulation and function, we performed mass spectrometry (MS)-based TAK1 interactomics. In addition to the identification of known and novel TAK1 interacting proteins, including TRIM28, CDC37 and STOML2, analysis of the MS data revealed various post-translational modifications within the TAK1/TAB complex. By applying siRNAs, TRIM28 and CDC37 were found to regulate phosphorylations of TAK1, IkappaB kinases IKKalpha/IKKbeta and MAP kinases, NF-kappaB transactivation activity and IL-8 expression in the infected epithelial cells. PMID- 29581851 TI - MiR-124 aggravates failing hearts by suppressing CD151-facilitated angiogenesis in heart. AB - Heart failure (HF) is the final common pathway of various cardiovascular diseases. Although it is well documented that reduction of cardiac angiogenesis contributes to the progression from adaptive cardiac hypertrophy to HF, the molecular mechanisms remain unknown. In the present study, we found that cardiac expression of miR-124 was increased in patients and mice with HF. Recombinant adeno-associated virus (rAAV)-mediated miR-124 over-expression aggravated angiotensin II (Ang II) infusion-induced cardiac dysfunction and abnormal cardiac angiogenesis in mice. In vitro, transfection of miR-124 mimics significantly promoted apoptosis and reduced viability, migration, tube formation, and nitric oxide release in endothelial cells. In addition, CD151 was identified as a direct target of miR-124. Endothelial cell injury caused by CD151 silencing was mimicked by miR-124 over-expression. Re-expression of CD151 attenuated miR-124-mediated suppression of cardiac angiogenesis and cardiac dysfunction in Ang II-treated mice. Our observations suggest that miR-124 is an important negative regulator of cardiac angiogenesis and cardiac function, likely by suppressing the expression of CD151 in heart cells. Modulation of miR-124 levels may provide new strategies and targets for HF therapy. PMID- 29581852 TI - RhoA/Rho-kinase triggers epithelial-mesenchymal transition in mesothelial cells and contributes to the pathogenesis of dialysis-related peritoneal fibrosis. AB - Peritoneal fibrosis (PF) with associated peritoneal dysfunction is almost invariably observed in long-term peritoneal dialysis (PD) patients. Advanced glycation end products (AGEs) are pro-oxidant compounds produced in excess during the metabolism of glucose and are present in high levels in standard PD solutions. The GTPase RhoA has been implicated in PF, but its specific role remains poorly understood. Here, we studied the effects of RhoA/Rho-kinase signaling in AGEs-induced epithelial-mesenchymal transition (EMT) in human peritoneal mesothelial cells (HPMCs), and evaluated morphological and molecular changes in a rat model of PD-related PF. Activation of RhoA/Rho-kinase and activating protein-1 (AP-1) was assessed in HPMCs using pull-down and electrophoretic mobility shift assays, respectively, while expression of transforming growth factor-beta, fibronectin, alpha-smooth muscle actin, vimentin, N-cadherin, and E-cadherin expression was assessed using immunohistochemistry and western blot. AGEs exposure activated Rho/Rho-kinase in HPMCs and upregulated EMT-related genes via AP-1. These changes were prevented by the Rho-kinase inhibitors fasudil and Y-27632, and by the AP-1 inhibitor curcumin. Importantly, fasudil normalized histopathological and molecular alterations and preserved peritoneal function in rats. These data support the therapeutic potential of Rho-kinase inhibitors in PD-related PF. PMID- 29581853 TI - The protective autophagy activated by GANT-61 in MYCN amplified neuroblastoma cells is mediated by PERK. AB - The proto-oncogene MYC can trigger the unfolded protein response (UPR). The double-stranded RNA-activated protein kinase-like endoplasmic reticulum kinase (PERK), one of three primary branches of the UPR, is a key regulator of autophagy, promoting tumorigenesis. Upon activation of PERK, there is an increase in phosphorylation of the eukaryotic initiation factor-2 alpha (eIF2alpha), which in turn, activates the transcription factor-4 (ATF4), responsible for an increased expression of LC3, a common autophagy marker. PERK is repressed upon GLI1 and GLI2 induction. GANT-61 is an inhibitor of GLI1 and GLI2, known to reduce autophagy in MYCN non-amplified, but not in MYCN amplified neuroblastoma (NB) cells. In our study, we tested the effect of the joint administration of a PERK inhibitor (GSK2606414) and the GLI inhibitor GANT-61 to MYCN amplified and MYCN non-amplified NB cells. Our results suggest that inhibition of PERK impairs GANT-61 induced autophagy in NB cells with MYCN amplification, but had no effect on the MYCN non-amplified NB cells. In summary, PERK seems to be a good therapeutic target for NB. Inhibition of PERK reduces autophagy in MYCN amplified NB cells, thus amplifying the efficacy of the GLI inhibitor GANT-61 in reducing proliferation of this type of cancer cells. PMID- 29581854 TI - IRE1alpha-XBP1 inhibitors exerted anti-tumor activities in Ewing's sarcoma. AB - Ewing's sarcoma (ES) is the second-most frequent pediatric bone tumor. Chromosomal translocation t(11;22)(q24:q12) results in the formation of EWS/FLI1 gene fusion, which is detected in approximately 90% of tumors of the Ewing family. Several transcriptome studies have provided lists of genes associated with EWS/FLI1 expression. However, the protein expression profiles associated with EWS/FLI1 have yet to be elucidated. In this study, to identify the regulated proteins associated with EWS/FLI1 and therapeutic targets in ES, we conducted proteomic studies using EWS/FLI1 knockdown in four Ewing's sarcoma cell lines and human mesenchymal stem cells (hMSCs) expressing EWS/FLI1. Isobaric tags for relative and absolute quantitation (i-TRAQ) analyses identified more than 2,000 proteins regulated by the EWS/FLI1 fusion. In addition, the network analyses identified several critical pathways, including XBP1, which was ranked the highest. XBP1 is a protein well known to play an important role in the unfolded protein response (UPR) to endoplasmic reticulum (ER) stress through the IRE1alpha XBP1 pathway. We confirmed the high mRNA expression of XBP1 (spliced XBP1 and unspliced XBPl) in surgical samples and cell lines in ES. The silencing of XBP1 significantly suppressed the cell viabilities in ES cell lines. In the inhibitor assays using IRE1alpha-XBP1 inhibitors, including toyocamycin, we confirmed that these agents significantly suppressed the cell viabilities, leading to apoptosis in ES cells both in vitro and in vivo. Our findings suggested that IRE1alpha-XBP1 inhibitors might be useful for developing novel therapeutic strategies in ES. PMID- 29581855 TI - Association between angiotensin II receptor type 1 A1166C polymorphism and chronic kidney disease. AB - Studies of the association between angiotensin II receptor type 1 A1166C (AGTR1 A1166C) polymorphism and chronic kidney disease (CKD) risk have yielded conflicting results. We conducted a combined case-control study and meta-analysis to better define this association. The case-control study included 634 end-stage renal disease (ESRD) patients and 739 healthy controls. AGTR1 A1166C genotype was determined using polymerase chain reaction and iPLEX Gold SNP genotyping methods. The meta-analysis included 24 studies found in the PubMed and Cochrane Library databases. Together, the case-control study and meta-analysis included 36 populations (7,918 cases and 6,905 controls). We found no association between the C allele and ESRD (case-control study: OR: 1.02, 95% CI: 0.77-1.37; meta analysis: OR: 1.07; 95% CI: 0.97-1.18). Co-dominant, dominant, and recessive model results were also not significant. No known environmental factors moderated the effect of AGTR1 A1166C on CKD in our gene-environment interaction analysis. Sensitivity analysis showed an AGTR1 A1166C-CKD association in Indian populations (OR: 1.46, 95% CI: 1.26-1.69), but not in East Asian or Caucasian populations. Additional South Asian studies will be required to confirm the potential role of this polymorphism in CKD. PMID- 29581856 TI - Fibroblast growth factor receptor signaling plays a key role in transformation induced by the TMPRSS2/ERG fusion gene and decreased PTEN. AB - Prostate cancer is the most common visceral malignancy and the second leading cause of cancer deaths in US men. Correlative studies in human prostate cancers reveal a frequent association of the TMPRSS2/ERG (TE) fusion gene with loss of PTEN and studies in mouse models reveal that ERG expression and PTEN loss synergistically promote prostate cancer progression. To determine the mechanism by which ERG overexpression and PTEN loss leads to transformation, we overexpressed the TE fusion gene and knocked down PTEN in an immortalized but non transformed prostate epithelial cell line. We show that ERG overexpression in combination with PTEN loss can transform these immortalized but non-tumorigenic cells, while either alteration alone was not sufficient to fully transform these cells. Expression microarray analysis revealed extensive changes in gene expression in cells expressing the TE fusion with loss of PTEN. Among these gene expression changes was increased expression of multiple FGF ligands and receptors. We show that activation of fibroblast growth factor receptor signaling plays a key role in transformation induced by TE fusion gene expression in association with PTEN loss. In addition, in vitro and in silico analysis reveals PTEN loss is associated with widespread increases in FGF ligands and receptors in prostate cancer. Inhibitors of FGF receptor signaling are currently entering the clinic and our results suggests that FGF receptor signaling is a therapeutic target in cancers with TE fusion gene expression and PTEN loss. PMID- 29581857 TI - Trends in the prevalence of congenital hydrocephalus in 14 cities in Liaoning province, China from 2006 to 2015 in a population-based birth defect registry from the Liaoning Women and Children's Health Hospital. AB - The aim of this study was to assess the prevalence and trends of congenital hydrocephalus (CH) using a large population-based sample with cases retrieved from the Liaoning Birth Defects Registry, which included 14 cities, over a 10 year period. CH prevalence, percent change, average change, and contribution rates of each city were calculated. Statistical analysis was performed using a Poisson regression model. There was a total of 3008 CH cases among 3,248,954 live births during the observational period (9.26 cases/10,000 live births). On average, the prevalence of CH had significantly decreased by 11.84% each year (P < 0.01). The three leading cities with the highest prevalence of CH were Chaoyang (13.73/10,000), Huludao (13.18/10,000), and Fuxin (12.71/10,000), while Yingkou (6.06/10,000), Dalian (6.27/10,000), and Anshan (6.56/10,000) had the lowest prevalence. Notably, significantly decreasing trends were observed in 10 (71.4%) of these 14 cities. In addition, the cities of Fushun, Shenyang, and Dalian had contributed to more than one-third of the decreasing trend in Liaoning province. In conclusion, this study provides evidence of the decreasing prevalence of CH over a 10-year period (2006-2015) in Liaoning province. Preventative efforts should be strengthened to further reduce the risk of CH in these high prevalence areas. PMID- 29581858 TI - Depleting ovarian cancer stem cells with calcitriol. AB - Cancer stem cells (CSCs) represent the root of many solid tumors including ovarian cancer. Eradication of CSCs represents a novel cancer therapeutic strategy. Calcitriol, also known as 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], is an active metabolite of vitamin D, functioning as a potent steroid hormone. Calcitriol has shown anti-tumor effects in various cancers by regulating multiple signaling pathways. It has been reported that calcitriol can regulate the properties of normal and CSCs. However, the effect of calcitriol on the ovarian cancer growth and ovarian CSCs is still unclear. Here, by using a mouse subcutaneous xenograft model generated with human ovarian cancer cells, we have demonstrated that administration of calcitriol is able to strikingly delay the tumor growth. Calcitriol treatment can also deplete the ovarian CSC population characterized by ALDH+ and CD44+CD117+; decrease their capacity to form sphere under the CSC culture condition, and reduce the frequency of tumor-initiating cells, as evaluated by in vivo limiting dilution analysis. Mechanistic investigation revealed that calcitriol depletes CSCs via the nuclear vitamin D receptor (VDR)-mediated inhibition of the Wnt pathway. Furthermore, the activation of VDR pathway is more sensitive to calcitriol in ovarian CSCs than in non-CSCs, although the expression levels of VDR are comparable. Taken together, our data indicate that calcitriol is able to deplete the ovarian CSC population by inhibiting their Wnt signaling pathway, consequently, impeding the growth of xenograft tumors. PMID- 29581859 TI - A pilot study on primary cultures of human respiratory tract epithelial cells to predict patients' responses to H7N9 infection. AB - Avian influenza A(H7N9) virus infections frequently lead to acute respiratory distress syndrome and death in humans. We aimed to investigate whether primary cultures of human respiratory tract epithelial cells are helpful to understand H7N9 virus pathogenesis and tissue tropism, and to evaluate how patient-related characteristics can affect the host's response to infection. Normal human bronchial epithelial cells (isolated from two different donors) and primary epithelial cells (harvested from 27 patients undergoing airway surgery) were experimentally infected with H7N9 and/or H1N1pdm for 72 h. After virus infection, the culture media were collected for viral RNA quantitation and cytokine detection. Both H7N9 and H1N1pdm viruses replicated and induced a cytokine response differently for each donor in the normal human bronchial epithelial model. H7N9 replicated equivalently in epithelial cells harvested from the inferior turbinate and paranasal sinus, and those from the larynx and bronchus, at 72 h post-infection. Viral RNA quantity at 72 h was significantly higher in patients aged 21-64 years than in patients aged >= 65 years; however, no effects of sex, medical comorbidities, and obesity were noted. H7N9-infected cultured cells released multiple cytokines within 72 h. Levels of interleukin-1beta, interleukin-6, interleukin-8, interferon-gamma, and tumor necrosis factor-alpha were associated differently with patient-related characteristics (such as age, sex, obesity, and medical comorbidities). In the era of precision medicine, these findings illustrate the potential utility of this primary culture approach to predict a host's response to H7N9 infection or to future infection by newly emerging viral infections, and to dissect viral pathogenesis.

AB - Despite recent advances in intensive chemotherapy treatments, long-term success is achieved in less than 30% of children with high-risk neuroblastoma (NB). Key regulatory pathways including the PI3K/Akt, mTOR and NF-kappaB are implicated in the pathogenesis of NB. Although drugs targeting these individual pathways are in clinical trials, they are not effective due to the activation of compensatory mechanisms. We have previously reported that natural novel withanolides from Physalis longifolia can potently inhibit these key regulatory pathways simultaneously. In the present study, we examined the efficacy and mechanisms through which novel withanolides and their acetate derivatives (WGA-TA and WGB DA) from P.longifolia kill NB cells. The results from the study demonstrated that our novel acetate derivatives are highly effective in inhibiting the proliferation, shifting the cell cycle and inducing apoptosis in a dose dependent manner. Analysis of oncogenic pathway proteins targeted by withanolides indicated induction of heat shock response due to oxidative stress. Dose dependent decrease in clients of HSP90 chaperone function due to suppression of Akt, mTOR, and NF kappaB pathways led to decrease in the expressions of target genes such as cyclin D1, N-myc and Survivin. Additionally, there was a dose dependent attenuation of the migration and invasion of NB cells. Furthermore, the lead compound WGA-TA showed significant reduction in tumor growth of NB xenografts. Taken together, these results suggest that withanolides are an effective therapeutic option against NBs. PMID- 29581861 TI - The circadian clock regulates cisplatin-induced toxicity and tumor regression in melanoma mouse and human models. AB - Cisplatin is one of the most commonly used chemotherapeutic drugs; however, toxicity and tumor resistance limit its use. Studies using murine models and human subjects have shown that the time of day of cisplatin treatment influences renal and blood toxicities. We hypothesized that the mechanisms responsible for these outcomes are driven by the circadian clock. We conducted experiments using wild-type and circadian disrupted Per1/2-/- mice treated with cisplatin at selected morning (AM) and evening (PM) times. Wild-type mice treated in the evening showed an enhanced rate of removal of cisplatin-DNA adducts and less toxicity than the morning-treated mice. This temporal variation in toxicity was lost in the Per1/2-/- clock-disrupted mice, suggesting that the time-of-day effect is linked to the circadian clock. Observations in blood cells from humans subjected to simulated day and night shift schedules corroborated this view. Per1/2-/- mice also exhibited a more robust immune response and slower tumor growth rate, indicating that the circadian clock also influences the immune response to melanoma tumors. Our findings indicate that cisplatin chronopharmacology involves the circadian clock control of DNA repair as well as immune responses, and thus affects both cisplatin toxicity and tumor growth. This has important implications for chronochemotherapy in cancer patients, and also suggests that influencing the circadian clock (e.g., through bright light treatment) may be explored as a tool to improve patient outcomes. PMID- 29581862 TI - Doxorubicin-induced loss of DNA topoisomerase II and DNMT1- dependent suppression of MiR-125b induces chemoresistance in ALK-positive cells. AB - Systemic anaplastic large-cell lymphoma (ALCL) is a childhood T cell neoplasm defined by the presence or absence of translocations that lead to the ectopic expression of anaplastic lymphoma kinase (ALK), with nucleophosmin-ALK (NPM-ALK) fusions being the most common. Polychemotherapy involving doxorubicin is the standard first-line treatment but for the 25 to 35% of patients who relapse and develop resistance the prognosis remains poor. We studied the potential role of the microRNA miR-125b in the development of resistance to doxorubicin in NPM ALK(+) ALCL. Our results show that miR-125b expression is repressed in NPM-ALK(+) cell lines and patient samples through hypermethylation of its promoter. NPM-ALK activity, in cooperation with DNA topoisomerase II (Topo II) and DNA methyltransferase 1 (DNMT1), is responsible for miR-125b repression through DNA hypermethylation. MiR-125b repression was reversed by the inhibition of DNMTs with decitabine or the inhibition of DNA topoisomerase II with either doxorubicin or etoposide. In NPM-ALK(+) cell lines, doxorubicin treatment led to an increase in miR-125b levels by inhibiting the binding of DNMT1 to the MIR125B1 promoter and downregulating the pro-apoptotic miR-125b target BAK1. Reversal of miR-125b silencing, increased miR-125b levels and reduced BAK1 expression also led to a lower efficacy of doxorubicin, suggestive of a pharmacoresistance mechanism. In line with this, miR-125b repression and increased BAK1 expression correlated with early relapse in human NPM-ALK(+) ALCL primary biopsies. Collectively our findings suggest that miR-125b could be used to predict therapeutic outcome in NPM-ALK(+) ALCL. PMID- 29581863 TI - Reduced SMAD2/3 activation independently predicts increased depth of human cutaneous squamous cell carcinoma. AB - The incidence of cutaneous squamous cell carcinoma (cSCC) is rising. Whilst the majority are cured surgically, aggressive metastatic cSCC carry a poor prognosis. Inactivating mutations in transforming growth factor beta (TGF-beta) receptors have been identified amongst genetic drivers of sporadic tumours and murine models of cSCC, suggesting a tumour suppressor function for TGF-beta in normal skin. However, paradoxically, TGF-beta acts as a tumour promoter in some murine model systems. Few studies have analysed the role of TGF-beta/activin signalling in human normal skin, hyper-proliferative skin disorders and cSCC. Antibodies recognising phospho-SMAD proteins which are activated during canonical TGF beta/activin signalling were validated for use in immunohistochemistry. A tissue microarray comprising FFPE lesional and perilesional tissue from human primary invasive cSCC (n=238), cSCC in-situ (n=2) and keratocanthoma (n=9) were analysed in comparison with tissues from normal human scalp (n=10). Phosphorylated SMAD2 and SMAD3 were detected in normal interfollicular epidermal keratinocytes and were also highly localised to inner root sheath, matrix cells and Keratin 15 positive cells. Lesional cSCC tissue had significantly reduced activated SMAD2/3 compared to perilesional tissue, consistent with a tumour suppressor role for SMAD2/3 activators in cSCC. Increased cSCC tumour thickness inversely correlated with the presence of phospho-SMADs in tumour tissue suggesting that a reduction in canonical TGF-beta/activin signalling may be associated with disease progression. PMID- 29581864 TI - Galectin-3 sensitized melanoma cell lines to vemurafenib (PLX4032) induced cell death through prevention of autophagy. AB - Melanoma is a current worldwide problem, as its incidence is increasing. In the last years, several studies have shown that melanoma cells display high levels of autophagy, a self-degradative process that can promote survival leading to drug resistance. Consequently, autophagy regulation represents a challenge for cancer therapy. Herein, we showed that galectin-3 (Gal-3), a beta-galactoside binding lectin which is often lost along melanoma progression, is a negative regulator of autophagy in melanoma cells. Our data demonstrated that Gal-3low/negative cells were more resistant to the inhibition of the activity of the cancer driver gene BRAFV600E by vemurafenib (PLX4032). Interestingly, in these cells, starvation caused further LC3-II accumulation in cells exposed to chloroquine, which inhibits the degradative step in autophagy. In addition, Gal-3 low/negative tumor cells accumulated more LC3-II than Gal-3 high tumor cells in vivo. Resistance of Gal-3low/negative cells was associated with increased production of superoxide and activation of the Endoplasmic Reticulum (ER) stress response, as evaluated by accumulation of GRP78. Pharmacological inhibition of autophagy with bafilomycin A reversed the relative resistance of Gal-3low/negative cells to vemurafenib treatment. Taken together, these results show that the autophagic flux is dependent on Gal-3 levels, which attenuate the prosurvival role of autophagy. PMID- 29581865 TI - Luminal breast cancer-specific circular RNAs uncovered by a novel tool for data analysis. AB - Circular RNAs are highly stable molecules present in all eukaryotes generated by distinct transcript processing. We have exploited poly(A-) RNA-Seq data generated in our lab in MCF-7 breast cancer cells to define a compilation of exonic circRNAs more comprehensive than previously existing lists. Development of a novel computational tool, named CircHunter, allowed us to more accurately characterize circRNAs and to quantitatively evaluate their expression in publicly available RNA-Seq data from breast cancer cell lines and tumor tissues. We observed and confirmed, by ChIP analysis, that exons involved in circularization events display significantly higher levels of the histone post-transcriptional modification H3K36me3 than non-circularizing exons. This result has potential impact on circRNA biogenesis since H3K36me3 has been involved in alternative splicing mechanisms. By analyzing an Ago-HITS-CLIP dataset we also found that circularizing exons overlapped with an unexpectedly higher number of Ago binding sites than non-circularizing exons. Finally, we observed that a subset of MCF-7 circRNAs are specific to tumor versus normal tissue, while others can distinguish Luminal from other tumor subtypes, thus suggesting that circRNAs can be exploited as novel biomarkers and drug targets for breast cancer. PMID- 29581866 TI - Calpastatin phosphorylation regulates radiation-induced calpain activity in glioblastoma. AB - Glioblastoma (GBM) is an aggressive, malignant brain tumor that inevitably develops resistance to conventional chemotherapy and radiation treatments. In order to identify signaling pathways involved in the development of radiation resistance, we performed mass spectrometry-based phospho-proteomic profiling of GBM cell lines and normal human astrocytes before and after radiation treatment. We found radiation induced phosphorylation of a number of proteins including calpastatin, specifically in GBM stem cells (GSCs). Herein, we focused on calpastatin, an endogenous inhibitor of calpain proteases. Radiation-induced phosphorylation of calpastatin at Ser-633 within the inhibitory domain was validated with a phospho-specific antibody. In order to test the functional significance of phosphorylated calpastatin, we utilized site-directed mutagenesis to generate phospho-inactive (Ser633Ala) and phospho-mimetic (Ser633Glu) mutant calpastatin. GBM cell lines stably expressing the mutant calpastatin showed that phosphorylation was necessary for radiation-induced calpain activation. We also showed that casein kinase 2, a pro-survival kinase overexpressed in many cancer types, phosphorylated calpastatin at Ser-633. Our results indicate that calpastatin phosphorylation promotes radiation resistance in GBM cells by increasing the activity of calpain proteases, which are known to promote survival and invasion in cancer. PMID- 29581867 TI - Long noncoding RNA ANRIL as a novel biomarker of lymph node metastasis and prognosis in human cancer: a meta-analysis. AB - Dysregulation of the long noncoding RNA antisense noncoding RNA in the INK4 locus (ANRIL) has been reported in various solid tumors. We performed a synthetic analysis to clarify the clinical value of ANRIL as a prognostic indicator in malignant tumors. Article collection was conducted using several electronic databases, including PubMed, Web of Science, Medline, OVID and Embase (up to July 14 2017). Thirteen original studies and 1172 total patients were included in the meta-analysis. There was a significant positive association between the high expression level of ANRIL and lymph node metastasis (OR = 4.77, 95% CI: 2.30 9.91, P < 0.001) by a random effects model (I2 = 73.2, P = 0.001) and negative association with poor grade cancer (OR = 3.44, 95% CI: 1.68-7.08) by a random effects model (I2 = 77.9, P = 0.000). The results of the meta-analysis showed that overexpression of ANRIL is positively related to poor overall survival (OS) (pooled HR = 2.12, 95% CI: 1.78-2.53, P < 0.0001) by a fixed-effects model (I2 = 0%, P = 0.654) and poor disease-free survival (DFS) (HR = 2.10, 95% CI: 1.51 2.92, P < 0.001) by a fixed-effects model (I2 = 13.3%, P = 0.315) in human solid cancers. Statistically significant associations were also found with cancer type, analysis method, sample size, and follow-up time. In conclusion, ANRIL may serve as a novel biomarker for indicating lymph node metastasis and prognosis in human cancer. PMID- 29581868 TI - The efficacy and safety of paclitaxel and carboplatin with versus without bevacizumab in patients with non-small-cell lung cancer: a systematic review and meta-analysis. AB - Objectives: To investigate the efficacy and safety of Bevacizumab (Bev) used in combination with paclitaxel and carboplatin (PC), compared with PC alone in patients with advanced non-small-cell lung cancer (NSCLC). Materials and Methods: We searched the PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Chinese Biomedical Literature electronic databases, to identify randomized controlled trials of PC plus Bev versus PC alone for the treatment of NSCLC. The meta-analysis was performed using Reviewer Manager Version 5.3 software provided by the Cochrane Collaboration. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were overall survival (OS), objective response rate (ORR), the incidence of severe adverse events and treatment-related deaths. Results: The final analysis included 5 trials with a total of 1486 patients. Compared with PC alone, the regimen of PC plus Bev resulted in significantly longer PFS (HR = 0.57; 95% CI = 0.46 to 0.71; p < 0.00001), longer OS (HR = 0.81; 95% CI = 0.71 to 0.92; p = 0.0009) and higher response rates (RR = 2.06; 95% CI = 1.73 to 2.44; p < 0.00001). However, grade >= 3 neutropenia, haemoptysis, hypertension, proteinuria and bleeding events were more common among patients who received Bev, and these patients also experienced increased rates of treatment related death. Conclusions: Compared with PC alone, the combination of PC with Bev could prolong PFS, OS and RR for patients with advanced non-squamous NSCLC. However, this combination could lead to a higher toxicity profile. Therefore, the benefits and risks should be considered before making treatment decisions. PMID- 29581869 TI - Trigger pSA predicting recurrence from positive choline PET/CT with prostate cancer after initial treatment. AB - Purpose: To assess the relationship between the diagnostic accuracy of Choline positron emission tomography/computed tomography (PET/CT) and the trigger prostate-specific antigen (PSA) level in patients with a biochemical recurrence of prostate cancer. Materials and Methods: A meta-analysis was conducted to synthesize data across multiple studies. Results: The pooled sensitivity and specificity of choline PET/CT were 82% (95% Confidence Interval (CI):80-84%) and 92% (95%CI: 90-93%), respectively. The pooled sensitivity and specificity of 18F choline PET/CT were 81% (95%CI: 78-84%) and 90% (95%CI: 85-93%), respectively. The pooled sensitivity and specificity of 11C-choline PET/CT were 83% (95% CI: 80 86%) and 92% (95% CI: 90-94%), respectively. The pooled detection rate of 18F choline PET/CT and 11C-choline PET/CT were 58% (95% CI: 48-68%) and 58% (95%CI: 49-68%), respectively. Conclusions: Trigger PSA is an important risk factor for positive findings of Choline PET/CT and the detection rate of Choline PET/CT for recurrent prostate cancer increased in parallel with raises in PSA-values. Choline PET/CT got higher detection rate while the trigger PSA > 2ng/ml. PMID- 29581870 TI - Clinicopathological and prognostic significance of Twist overexpression in NSCLC. AB - Several studies were conducted to explore the prognostic significance of Twist in non-small cell lung cancer (NSCLC), however, contradictory results in different studies were reported. To this end, we presented a systematic review aiming to summarize the prognostic significance of Twist in patients with NSCLC. 5 studies involving a total of 572 patients were identified. The result indicated that high Twist expression was significantly associated with a worse overall survival (OS) (hazard ratio (HR) = 2.19, 95% confidence interval (95% CI) = 1.64-2.94, p < 0.001; I2 = 0.0%, fixed effect), recurrence-free survival (RFS) (HR = 2.476, 95% CI = 1.728-3.547, p < 0.001; I2 = 0.0%, fixed effect) and lymph node or other metastasis (odds rate (OR) = 0.419, 95% CI = 0.259-0.679, P < 0.001, fixed effect). Subgroup analysis revealed that the expression of Twist in Chinese patients might be more closely associated with the prognosis of NSCLC than in American patients. Overall, these results indicated that Twist over-expression in patients with NSCLC might be related to poor prognosis and serves as an unfavorable predictor of poor clinicopathological prognosis factor. PMID- 29581871 TI - Positive urinary fluorescence in situ hybridization indicates poor prognosis in patients with upper tract urothelial carcinoma. AB - Here, we evaluated the potential contribution of fluorescent in situ hybridization (FISH) as a prognostic risk factor of bladder recurrence and survival in patients with upper tract urothelial carcinoma (UTUC). A total of 159 UTUC patients were enrolled in this study from January 2012 to May 2016. The 159 voided urine samples before surgery were analyzed using the UroVysion(r) kit to detect the copy numbers of chromosomes 3, 7, 17 and 9p21 (p16). Patients were classified using an optimal cutoff value of chromosomes 3, 7, 17, and 9p21. Cox's proportional hazards regression model was used to assess the prognostic value of FISH for bladder recurrence and survival. We found that 27 (17.6%) patients experienced bladder recurrence and 26 (16.4%) patients died from cancer, with a median follow-up of 27 months. The patients with positive FISH result were more likely to present bladder recurrence (p = 0.077). However, positive FISH was not associated with cancer specific-free survival (CSS) (p = 0.944). Tumor multifocality, the percentage of abnormal chromosome 3 > 5%, chromosome 7 > 6%, chromosome 17 > 11% and deletion of p16 > 4% were significant prognostic risk factors for BRFS in univariate analysis. In multivariate analysis, only tumor multifocality (hazard ratio [HR] = 3.487, 95%CI: 1.605-7.576, p = 0.002) and the percentage of p16 loss > 4% were both prognostic risk factors for bladder recurrence (HR = 3.487, 95%CI: 1.605-7.576, p = 0.002). These data consider that the urinary FISH test could be a powerful tool in predicting the risk of bladder recurrence in patients with UTUC. PMID- 29581872 TI - Type 2 diabetes mellitus-related changes in left ventricular structure and function in patients with chronic kidney disease. AB - Type 2 Diabetes mellitus (DM) is the leading cause of chronic kidney disease (CKD) worldwide, and is associated with an increased risk of left ventricular (LV) hypertrophy, LV systolic and diastolic dysfunctions. The aim of this study was to investigate abnormal echocardiographic findings in patients with CKD with and without DM, and identify the factors associated with these abnormalities. We enrolled 356 pre-dialysis patients with CKD (stages 3-5), including 208 with DM and 148 without DM. The structure and systolic and diastolic functions of the left ventricle were assessed using echocardiography, and the clinical and echocardiographic parameters were analyzed. The patients with DM had higher rates of observed/predicted left ventricular mass > 128% (69.5% vs. 56.7%, p = 0.015), midwall fractional shortening < 14% (22.6% vs. 8.8%, p = 0.001), and ratio of peak early transmitral filling wave velocity to early diastolic velocity of lateral mitral annulus > 12 (32.7% vs. 16.2%, p < 0.001) than those without DM. Multivariate analysis showed that male sex, a history of smoking, high systolic blood pressure, high body mass index, high levels of fasting glucose and total cholesterol, low levels of albumin and hemoglobin, and a low estimated glomerular filtration rate were associated with abnormal echocardiographic findings. The rates of inappropriate left ventricular mass, systolic and diastolic dysfunction were higher in our patients with CKD and DM than in those without DM. PMID- 29581873 TI - Healthy efficacy of Nostoc commune Vaucher. AB - Nostoc commune Vaucher, a macroscopic cyanobacterium, has long been appreciated as a healthy food and traditional medicine worldwide. Accumulated evidence has demonstrated that it possesses a wide range of remarkably protective physiological and pharmacological activities, largely based on animal and in vitro studies. In this review, we summarise and update evidence regarding the chemical composition and nutritional characteristics of Nostoc commune Vaucher, and comprehensively discuss the recent studies on the antioxidative, anti inflammatory, anti-carcinogenic and immune regulation properties of Nostoc commune Vaucher and Nostoc commune Vaucher-derived extracts. The available results demonstrate the potential of it to act as a functional food for the amelioration of human associated diseases. More details from human clinical trials should be a matter of further investigation. PMID- 29581874 TI - Old Sonic Hedgehog, new tricks: a new paradigm in thoracic malignancies. AB - The Sonic Hedgehog (Shh) pathway is physiologically involved during embryogenesis, but is also activated in several diseases, including solid cancers. Previous studies have demonstrated that the Shh pathway is involved in oncogenesis, tumor progression and chemoresistance in lung cancer and mesothelioma. The Shh pathway is also closely associated with epithelial mesenchymal transition and cancer stem cells. Recent findings have revealed that a small proportion of lung cancer cells expressed an abnormal full-length Shh protein, associated with cancer stem cell features. In this paper, we review the role of the Shh pathway in thoracic cancers (small cell lung cancer, non-small cell lung cancer, and mesothelioma) and discuss the new perspectives of cancer research highlighted by the recent data of the literature. PMID- 29581877 TI - Immune checkpoint inhibitors in large cell neuroendocrine carcinoma: current status. AB - Introduction: Large cell neuroendocrine carcinomas (LCNEC) are a group of rare high grade neuroendocrine tumors that often behave clinically like small cell carcinoma (SCLC) and are treated as such. No major advancement in the management of these tumors has occurred in the last 30 years. Methods: We present a case series of three cases from Markey Cancer center along with a review of 13 published cases in the literature wherein immune-checkpoint inhibitors were utilized in the management of LCNEC. Results: Immune-checkpoint inhibitors might have clinical activity in LCNEC. Conclusion: Role of immune-checkpoint inhibitors should be explored in prospective LCNEC clinical trials. We summarize current evidence regarding use of immune checkpoint inhibitors in the treatment of LCNEC. PMID- 29581876 TI - Prostatic cancers: understanding their molecular pathology and the 2016 WHO classification. AB - Accumulating evidence suggests that prostatic cancers represent a group of histologically and molecularly heterogeneous diseases with variable clinical courses. In accordance with the increased knowledge of their clinicopathologies and genetics, the World Health Organization (WHO) classification of prostatic cancers has been revised. Additionally, recent data on their comprehensive molecular characterization have increased our understanding of the genomic basis of prostatic cancers and enabled us to classify them into subtypes with distinct molecular pathologies and clinical features. Our increased understanding of the molecular pathologies of prostatic cancers has permitted their evolution from a poorly understood, heterogeneous group of diseases with variable clinical courses to characteristic molecular subtypes that allow the implementation of personalized therapies and better patient management. This review provides perspectives on the new 2016 WHO classification of prostatic cancers as well as recent knowledge of their molecular pathologies. The WHO classification of prostatic cancers will require additional revisions to allow for reliable and clinically meaningful cancer diagnoses as a better understanding of their molecular characteristics is obtained. PMID- 29581878 TI - The geometric preference subtype in ASD: identifying a consistent, early-emerging phenomenon through eye tracking. AB - Background: The wide range of ability and disability in ASD creates a need for tools that parse the phenotypic heterogeneity into meaningful subtypes. Using eye tracking, our past studies revealed that when presented with social and geometric images, a subset of ASD toddlers preferred viewing geometric images, and these toddlers also had greater symptom severity than ASD toddlers with greater social attention. This study tests whether this "GeoPref test" effect would generalize across different social stimuli. Methods: Two hundred and twenty-seven toddlers (76 ASD) watched a 90-s video, the Complex Social GeoPref test, of dynamic geometric images paired with social images of children interacting and moving. Proportion of visual fixation time and number of saccades per second to both images were calculated. To allow for cross-paradigm comparisons, a subset of 126 toddlers also participated in the original GeoPref test. Measures of cognitive and social functioning (MSEL, ADOS, VABS) were collected and related to eye tracking data. To examine utility as a diagnostic indicator to detect ASD toddlers, validation statistics (e.g., sensitivity, specificity, ROC, AUC) were calculated for the Complex Social GeoPref test alone and when combined with the original GeoPref test. Results: ASD toddlers spent a significantly greater amount of time viewing geometric images than any other diagnostic group. Fixation patterns from ASD toddlers who participated in both tests revealed a significant correlation, supporting the idea that these tests identify a phenotypically meaningful ASD subgroup. Combined use of both original and Complex Social GeoPref tests identified a subgroup of about 1 in 3 ASD toddlers from the "GeoPref" subtype (sensitivity 35%, specificity 94%, AUC 0.75.) Replicating our previous studies, more time looking at geometric images was associated with significantly greater ADOS symptom severity. Conclusions: Regardless of the complexity of the social images used (low in the original GeoPref test vs high in the new Complex Social GeoPref test), eye tracking of toddlers can accurately identify a specific ASD "GeoPref" subtype with elevated symptom severity. The GeoPref tests are predictive of ASD at the individual subject level and thus potentially useful for various clinical applications (e.g., early identification, prognosis, or development of subtype-specific treatments). PMID- 29581875 TI - Vive la radioresistance!: converging research in radiobiology and biogerontology to enhance human radioresistance for deep space exploration and colonization. AB - While many efforts have been made to pave the way toward human space colonization, little consideration has been given to the methods of protecting spacefarers against harsh cosmic and local radioactive environments and the high costs associated with protection from the deleterious physiological effects of exposure to high-Linear energy transfer (high-LET) radiation. Herein, we lay the foundations of a roadmap toward enhancing human radioresistance for the purposes of deep space colonization and exploration. We outline future research directions toward the goal of enhancing human radioresistance, including upregulation of endogenous repair and radioprotective mechanisms, possible leeways into gene therapy in order to enhance radioresistance via the translation of exogenous and engineered DNA repair and radioprotective mechanisms, the substitution of organic molecules with fortified isoforms, and methods of slowing metabolic activity while preserving cognitive function. We conclude by presenting the known associations between radioresistance and longevity, and articulating the position that enhancing human radioresistance is likely to extend the healthspan of human spacefarers as well. PMID- 29581879 TI - Transport of charged small molecules after electropermeabilization - drift and diffusion. AB - Background: Applications of electric-field-induced permeabilization of cells range from cancer therapy to wastewater treatment. A unified understanding of the underlying mechanisms of membrane electropermeabilization, however, has not been achieved. Protocols are empirical, and models are descriptive rather than predictive, which hampers the optimization and expansion of electroporation-based technologies. A common feature of existing models is the assumption that the permeabilized membrane is passive, and that transport through it is entirely diffusive. To demonstrate the necessity to go beyond that assumption, we present here a quantitative analysis of the post-permeabilization transport of three small molecules commonly used in electroporation research - YO-PRO-1, propidium, and calcein - after exposure of cells to minimally perturbing, 6 ns electric pulses. Results: Influx of YO-PRO-1 from the external medium into the cell exceeds that of propidium, consistent with many published studies. Both are much greater than the influx of calcein. In contrast, the normalized molar efflux of calcein from pre-loaded cells into the medium after electropermeabilization is roughly equivalent to the influx of YO-PRO-1 and propidium. These relative transport rates are correlated not with molecular size or cross-section, but rather with molecular charge polarity. Conclusions: This comparison of the kinetics of molecular transport of three small, charged molecules across electropermeabilized cell membranes reveals a component of the mechanism of electroporation that is customarily taken into account only for the time during electric pulse delivery. The large differences between the influx rates of propidium and YO-PRO-1 (cations) and calcein (anion), and between the influx and efflux of calcein, suggest a significant role for the post-pulse transmembrane potential in the migration of ions and charged small molecules across permeabilized cell membranes, which has been largely neglected in models of electroporation. PMID- 29581880 TI - Imputation from SNP chip to sequence: a case study in a Chinese indigenous chicken population. AB - Background: Genome-wide association studies and genomic predictions are thought to be optimized by using whole-genome sequence (WGS) data. However, sequencing thousands of individuals of interest is expensive. Imputation from SNP panels to WGS data is an attractive and less expensive approach to obtain WGS data. The aims of this study were to investigate the accuracy of imputation and to provide insight into the design and execution of genotype imputation. Results: We genotyped 450 chickens with a 600 K SNP array, and sequenced 24 key individuals by whole genome re-sequencing. Accuracy of imputation from putative 60 K and 600 K array data to WGS data was 0.620 and 0.812 for Beagle, and 0.810 and 0.914 for FImpute, respectively. By increasing the sequencing cost from 24X to 144X, the imputation accuracy increased from 0.525 to 0.698 for Beagle and from 0.654 to 0.823 for FImpute. With fixed sequence depth (12X), increasing the number of sequenced animals from 1 to 24, improved accuracy from 0.421 to 0.897 for FImpute and from 0.396 to 0.777 for Beagle. Using optimally selected key individuals resulted in a higher imputation accuracy compared with using randomly selected individuals as a reference population for re-sequencing. With fixed reference population size (24), imputation accuracy increased from 0.654 to 0.875 for FImpute and from 0.512 to 0.762 for Beagle as the sequencing depth increased from 1X to 12X. With a given total cost of genotyping, accuracy increased with the size of the reference population for FImpute, but the pattern was not valid for Beagle, which showed the highest accuracy at six fold coverage for the scenarios used in this study. Conclusions: In conclusion, we comprehensively investigated the impacts of several key factors on genotype imputation. Generally, increasing sequencing cost gave a higher imputation accuracy. But with a fixed sequencing cost, the optimal imputation enhance the performance of WGP and GWAS. An optimal imputation strategy should take size of reference population, imputation algorithms, marker density, and population structure of the target population and methods to select key individuals into consideration comprehensively. This work sheds additional light on how to design and execute genotype imputation for livestock populations. PMID- 29581881 TI - The association between Korean employed workers' on-call work and health problems, injuries. AB - Background: On-call work is a form of work that requires the person to work at any time during the on-call period. Thus, on-call work is often regarded as one of the most severe stress factors. This study investigates the associations between on-call work and health problems, injuries. Methods: This study was based on the 3rd Korean Working Conditions Survey. Total of 29,246 employed workers who had been working for at least 1 year were included. Logistic regression analysis was performed to investigate the association between on-call work and health problems, injuries. Results: The odds ratios for on-call workers in terms of physical health problems, psychological health problems, and injuries were 1.33 (95% confidence interval [CI] 1.22-1.44), 1.31 (95% CI 1.08-1.60), and 2.76 (95% CI 2.26-3.37), respectively. Analysis of the detailed symptoms revealed odds ratios in on-call workers of 2.06 for hearing problems (95% CI 1.63-2.62); 1.71 for skin problems (95% CI 1.38-2.12); 1.22 for back pain (95% CI 1.08-1.38); 1.23 for muscular pains in upper limbs (95% CI 1.12-1.34); 1.27 for muscular pains in lower limbs (95% CI 1.15-1.40); 1.46 for headache, eye fatigue (95% CI 1.32 1.60); 1.37 for abdominal pain (95% CI 1.02-1.85); 1.43 for depression or anxiety disorders (95% CI 1.07-1.93); 1.36 for fatigue (95% CI 1.24-1.49); and 1.41 for insomnia and general sleep difficulties (95% CI 1.13-1.76). Conclusions: The present study found that on-call work results in an increased risk of health problems and injuries. This study is the result of analyses of broad range of the job spectrum in Korean employed workers; thus, future studies are necessary to determine the effects of on-call work in various job groups. PMID- 29581882 TI - Developing gene-tagged molecular markers for evaluation of genetic association of apple SWEET genes with fruit sugar accumulation. AB - Sugar content is an important component of fruit quality. Although sugar transporters are known to be crucial for sugar accumulation, the role of genes encoding SWEET sugar transporters in fruit sugar accumulation remains elusive. Here we report the effect of the SWEET genes on fruit sugar accumulation in apple. A total of 25 MdSWEET genes were identified in the apple genome, and 9 were highly expressed throughout fruit development. Molecular markers of these 9 MdSWEET genes were developed and used for genotyping of 188 apple cultivars. The association of polymorphic MdSWEET genes with soluble sugar content in mature fruit was analyzed. Three genes, MdSWEET2e, MdSWEET9b, and MdSWEET15a, were significantly associated with fruit sugar content, with MdSWEET15a and MdSWEET9b accounting for a relatively large proportion of phenotypic variation in sugar content. Moreover, both MdSWEET9b and MdSWEET15a are located on chromosomal regions harboring QTLs for sugar content. Hence, MdSWEET9b and MdSWEET15a are likely candidates regulating fruit sugar accumulation in apple. Our study not only presents an efficient way of implementing gene functional study but also provides molecular tools for genetic improvement of fruit quality in apple breeding programs. PMID- 29581883 TI - NPR1 as a transgenic crop protection strategy in horticultural species. AB - The NPR1 (NONEXPRESSOR OF PATHOGENESIS RELATED GENES1) gene has a central role in the long-lasting, broad-spectrum defense response known as systemic acquired resistance (SAR). When overexpressed in a transgenic context in Arabidopsis thaliana, this gene enhances resistance to a number of biotic and abiotic stresses. Its position as a key regulator of defense across diverse plant species makes NPR1 a strong candidate gene for genetic engineering disease and stress tolerance into other crops. High-value horticultural crops face many new challenges from pests and pathogens, and their emergence exceeds the pace of traditional breeding, making the application of NPR1-based strategies potentially useful in fruit and vegetable crops. However, plants overexpressing NPR1 occasionally present detrimental morphological traits that make its application less attractive. The practical utility of NPR-based approaches will be a balance of resistance gains versus other losses. In this review, we summarize the progress on the understanding of NPR1-centered applications in horticultural and other crop plants. We also discuss the effect of the ectopic expression of the A. thaliana NPR1 gene and its orthologs in crop plants and outline the future challenges of using NPR1 in agricultural applications. PMID- 29581884 TI - The BC Glomerulonephritis Network: Improving Access and Reducing the Cost of Immunosuppressive Treatments for Glomerular Diseases. AB - Glomerulonephritis (GN) is a common cause of end-stage renal disease in Canada and worldwide, and results in significant health care resource utilization and patient morbidity. However, GN has not been a traditional priority of provincial renal health care organizations, despite the known benefits to health services delivery and patient outcomes from integrated provincial care in other types of chronic kidney disease. To address this deficiency, the British Columbia (BC) Provincial Renal Agency created the BC GN Network in 2013 to coordinate provincial GN health services delivery informed by robust population-level data capture on all GN patients in the province via the BC GN Registry. This report describes the use of the BC GN Network infrastructure to systematically develop and evaluate a provincial GN drug formulary to improve patient and physician access to evidence-based immunosuppressive treatments for GN in a cost-efficient manner that successfully halted historical trends of increasing medication costs. An example is provided of using the provincial infrastructure to implement and subsequently evaluate an evidence-informed health policy of converting brand to generic tacrolimus for the treatment of GN. The BC GN Network, including the provincial drug formulary and data infrastructure, is an example of the benefits of expanding the mandate of provincial renal health administrative organizations to include the care of patients with GN, and constitutes a viable health delivery model that can be implemented in other Canadian provinces to achieve similar goals. PMID- 29581885 TI - An Examination of the Application of the Kidney Donor Risk Index in British Columbia. AB - Background: The Kidney Donor Risk Index (KDRI) is a continuous measure of deceased donor kidney transplant failure risk that was derived in US patients based on 10 donor characteristics. In the United States, the KDRI is utilized to guide organ allocation and to inform clinical decisions regarding organ acceptance. Objective: To examine the application of the US-derived KDRI in a large Canadian province. Patients: All deceased donor kidney-only transplant recipients in British Columbia (BC) between 2005 and 2014. Methods: We examined the predictive performance of KDRI in BC transplant recipients and compared the overall performance of KDRI with donor age alone in predicting transplant failure (from all causes including death). Results: Donors in BC (N = 785) were older but included no black donors and few Hepatitis C virus (HCV)-positive donors compared with the original derivation cohort of the KDRI in the United States. The KDRI was moderately predictive of transplant failure (c statistic, 0.63) and had similar predictive performance to donor age alone (c statistic, 0.64). Conclusion: Our findings suggest that the US-derived KDRI does not improve the prediction of kidney transplant failure compared with donor age alone in a Canadian cohort and highlight the need to determine the applicability of KDRI in different regions. PMID- 29581886 TI - TRIM29 negatively controls antiviral immune response through targeting STING for degradation. AB - Innate immune system is armed by several lines of pattern recognition receptors to sense various viral infection and to initiate antiviral immune response. This process is under a tight control and the negative feedback induced by infection and/or inflammation is critical to maintain immune homoeostasis and to prevent autoimmune disorders, however, the molecular mechanism is not fully understood. Here we report TRIM29, a ubiquitin E3 ligase, functions as an inducible negative regulator of innate immune response triggered by DNA virus and cytosolic DNA. DNA virus and cytosolic DNA stimulation induce TRIM29 expression robustly in macrophages and dendritic cells, although the basal level of TRIM29 is undetectable in those cells. TRIM29 deficiency elevates IFN-I and proinflammatory cytokine production upon viral DNA and cytosolic dsDNA stimulation. Consistently, in vivo experiments show that TRIM29-deficient mice are more resistant to HSV-1 infection than WT controls, indicated by better survival rate and reduced viral load in organs. Mechanism studies suggest that STING-TBK1-IRF3 signaling pathway in TRIM29 KO cells is significantly enhanced and the degradation of STING is impaired. Furthermore, we identify that TRIM29 targets STING for K48 ubiquitination and degradation. This study reveals TRIM29 as a crucial negative regulator in immune response to DNA virus and cytosolic DNA, preventing potential damage caused by overcommitted immune responses. PMID- 29581888 TI - Concerns on a new therapy for severe heart failure using cell sheets with skeletal muscle or myocardial cells from iPS cells in Japan. AB - In Japan, a new therapy for severe heart failure using skeletal myocardial sheet is ongoing and a treatment using iPS cells is just about to start. However, I think there are problems and concerns. In this comment, I will express concerns on these treatments. This will be useful and interesting to stem cell researchers and clinical cardiologists. PMID- 29581887 TI - Improving imputation in disease-relevant regions: lessons from cystic fibrosis. AB - Does genotype imputation with public reference panels identify variants contributing to disease? Genotype imputation using the 1000 Genomes Project (1KG; 2504 individuals) displayed poor coverage at the causal cystic fibrosis (CF) transmembrane conductance regulator (CFTR) locus for the International CF Gene Modifier Consortium. Imputation with the larger Haplotype Reference Consortium (HRC; 32,470 individuals) displayed improved coverage but low sensitivity of variants clinically relevant for CF. A hybrid reference that combined whole genome sequencing (WGS) from 101 CF individuals with the 1KG imputed a greater number of single-nucleotide variants (SNVs) that would be analyzed in a genetic association study (r2 >= 0.3 and MAF >= 0.5%) than imputation with the HRC, while the HRC excelled in the lower frequency spectrum. Using the 1KG or HRC as reference panels missed the most common CF-causing variants or displayed low imputation accuracy. Designs that incorporate population-specific WGS can improve imputation accuracy at disease-specific loci, while imputation using public data sets can omit disease-relevant genotypes. PMID- 29581889 TI - Non-traumatic myelopathy associated with prolonged hyperextension during swimming: an unusual variation of Surfer's Myelopathy. AB - Introduction: Surfer's myelopathy (SM) is a rare cause on non-traumatic acute myelopathy. This has classically been described in novice surfers however has been reported in other scenarios. Case presentation: We present a case of non traumatic paraparesis associated with prolonged cervical hyperextension during swimming with imaging characteristics consistent with an unusual variation of SM in a swimmer. Discussion: SM and its variants should be considered in the differential diagnosis of any patient presenting with an anterior spinal cord syndrome with a history of either sustained or repeated spinal hyperextension. PMID- 29581890 TI - Recurrent discitis in the acute rehab setting: a case report. AB - Introduction: Discitis is an infection of the intervertebral disc space that can lead to paralysis, sepsis, epidural abscess, or other life-threatening complications if left untreated and may sometimes present with limited laboratory abnormalities to clue a diagnosis. Case presentation: We present a case of a 67 year-old female in an acute rehabilitation setting who had presenting symptoms of sudden unexplained back pain refractory to pain control. She had a previous history of discitis and multiple failed knee replacement surgeries secondary to MSSA infections. Although vitals and basic labs were within normal limits, we recognized the clinical presentation as an indicator to order inflammatory markers (CPR and ESR), which were elevated compared to levels on admission, and subsequently ordered imaging and blood cultures to detect a case of recurrent worsening discitis. Discussion: We highlight the presentation of recurrent discitis and necessary low threshold needed to detect such recurrence in patients with a previous history of discitis that have sudden unexplained back pain with no other usual physical or laboratory indicators of infection. PMID- 29581891 TI - Multifocal primary melanoma of the cervical spinal cord successfully treated by tumorectomy: a case report. AB - Introduction: Multifocal primary melanoma of the spine is extremely rare. Here, we report a case of multifocal primary melanoma of the cervical spinal cord. Case presentation: A 39-year-old man presented with a 1-year history of numbness of the upper extremities and back. Magnetic resonance imaging of the cervical spine suggested multifocal intradural extramedullary tumors at levels C2 and C4-C5. A diagnostic biopsy revealed a pathological diagnosis of malignant melanoma. Tumorectomy was then performed. The numbness in the patient's upper extremities improved, and he was discharged. As of 2 years after surgery, no signs of local or systemic recurrence have been noted. Discussion: Primary melanoma of the spinal cord usually carries a poor prognosis. However, in this case, the outcome following tumorectomy has been highly favorable. We speculate that this is because the MIB-1 labeling index of the tumors was less than 1%. PMID- 29581892 TI - Primary intramedullary spinal cord tumour in pregnancy: a case report. AB - Introduction: Primary spinal cord tumours can lead to severe neurological complications and even death. Pregnant women often complain of discomfort of the lower limbs, which is usually caused by sciatica. Here we present the case of a pregnant woman, who was initially considered to have sciatica, but was finally diagnosed with a primary intramedullary spinal cord tumour. Case presentation: A 28-year-old pregnant woman presented to our hospital with inexplicable numbness in her lower limbs. She was initially considered to have sciatica, but acute deterioration of neurological symptoms and plain magnetic resonance imaging (MRI) findings suggested malignancy. The patient was finally diagnosed with a primary intramedullary spinal cord tumour at the C3-Th5 region. An emergency caesarean section was performed, after which the spinal cord lesion was evaluated using contrast-enhanced MRI, positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-d-glucose integrated with computed tomography, and spinal angiography, and further treatment was initiated. However, while the patient's spinal cord tumour surgery was performed in early postpartum, her paraplegia and bladder and rectal disturbances remained unchanged even 1 year after surgery. Discussion: Because of the low incidence of spinal cord tumours during pregnancy, no definite reports have been published on the treatment of pregnant patients with spinal cord tumours. Although safe imaging tests during pregnancy are limited, intervention in such patients should be performed as early as possible to avoid irreversible neurological deterioration. PMID- 29581893 TI - Effect of indoor wheelchair curling training on trunk control of person with chronic spinal cord injury: a randomised controlled trial. AB - Study design: Randomised, controlled, single-blind crossover design study. Objective: Effect of indoor wheelchair curling training on trunk control of a person with chronic spinal cord injury (SCI). Setting: SCI Centre of Balgrist University Hospital in Zurich, Switzerland. Methods: The trunk control of 13 subjects was assessed by the modified functional reach test (MFRT) and nonlinear dynamic systems analysis (NDSA) before and after eight indoor curling training sessions and compared to everyday life over 4 weeks. Results: The attendance rate was 95% during the training sessions. There were no adverse events. Neither the MRFT nor the NDSA showed any significant differences in the sitting stability. The subjects subjectively reported improved physical feeling, an increase in their trunk control and strength; 39% of the participants wanted to continue the training. Conclusions: With subjective improvements and no adverse events, indoor wheelchair curling training is a safe physical activity for people with SCI. Wheelchair curling offers a suitable alternative to sports already used in rehabilitation and in recreational activities of a person with SCI. In order to be able to draw more unambiguous conclusions from the training method for trunk control and to answer the question of the study unambiguously, the number of subjects would have to be greater and the test methods should provide more exact and specific measurements. PMID- 29581895 TI - Methamphetamine alters T cell cycle entry and progression: role in immune dysfunction. AB - We and others have demonstrated that stimulants such as methamphetamine (METH) exerts immunosuppressive effects on the host's innate and adaptive immune systems and has profound immunological implications. Evaluation of the mechanisms responsible for T-cell immune dysregulation may lead to ways of regulating immune homeostasis during stimulant use. Here we evaluated the effects of METH on T cell cycle entry and progression following activation. Kinetic analyses of cell cycle progression of T-cell subsets exposed to METH demonstrated protracted G1/S phase transition and differentially regulated genes responsible for cell cycle regulation. This result was supported by in vivo studies where mice exposed to METH had altered G1 cell cycle phase and impaired T-cell proliferation. In addition, T cells subsets exposed to METH had significant decreased expression of cyclin E, CDK2 and transcription factor E2F1 expression. Overall, our results indicate that METH exposure results in altered T cell cycle entry and progression. Our findings suggest that disruption of cell cycle machinery due to METH may limit T-cell proliferation essential for mounting an effective adaptive immune response and thus may strongly contribute to deleterious effect on immune system. PMID- 29581894 TI - Genetic and pharmacological inhibition of Cdk1 provides neuroprotection towards ischemic neuronal death. AB - Cell cycle proteins are mainly expressed by dividing cells. However, it is well established that these molecules play additional non-canonical activities in several cell death contexts. Increasing evidence shows expression of cell cycle regulating proteins in post-mitotic cells, including mature neurons, following neuronal insult. Several cyclin-dependent kinases (Cdks) have already been shown to mediate ischemic neuronal death but Cdk1, a major cell cycle G2/M regulator, has not been investigated in this context. We therefore examined the role of Cdk1 in neuronal cell death following cerebral ischemia, using both in vitro and in vivo genetic and pharmacological approaches. Exposure of primary cortical neurons cultures to 4 h of oxygen-glucose deprivation (OGD) resulted in neuronal cell death and induced Cdk1 expression. Neurons from Cdk1-cKO mice showed partial resistance to OGD-induced neuronal cell death. Addition of R-roscovitine to the culture medium conferred neuroprotection against OGD-induced neuronal death. Transient 1-h occlusion of the cerebral artery (MCAO) also leads to Cdk1 expression and activation. Cdk1-cKO mice displayed partial resistance to transient 1-h MCAO. Moreover, systemic delivery of R-roscovitine was neuroprotective following transient 1-h MCAO. This study demonstrates that promising neuroprotective therapies can be considered through inhibition of the cell cycle machinery and particularly through pharmacological inhibition of Cdk1. PMID- 29581896 TI - Chasing the signaling run by tri-molecular time-lapse FRET microscopy. AB - A feasible design is made to measure three protein/protein interactions to visualize signal pathways by time-lapse Forster resonance energy transfer (FRET) microscopy. When interacting proteins are in close proximity, excitation energy is provided to allow the energy flow from the first molecule to excite the second, followed by energy transfer to the third. By phorbol ester/calcium ionophore stimulation, for example, a real-time complex formation of ectopic IkappaBalpha/ERK/WWOX occurs as measured by FRET microscopy, indicative of an ongoing functional signaling. Hyaluronan induces membrane Hyal-2 signaling, which allows FRET measurement of the complex formation of ectopic Smad4/WWOX/Hyal-2 for causing bubbling cell death. If ectopic p53 is recruited to replace Hyal-2, the resulting ectopic Smad4/WWOX/p53 complex induces membrane blebbing without cell death. Together, in this perspective review article, we demonstrate the utilization of time-lapse FRET microscopy to visualize the signaling event via the tri-molecular protein complex formation and their biological outcomes. We show an initial two-protein binding to form the driving force to jumpstart the tri-molecular execution for the signal pathway. PMID- 29581898 TI - Giant Left Ventricular Thrombus in a Patient with Acute Ischemic Stroke: A Case Report and Minireview. AB - A 56-year-old healthy male with no obvious risk factors or significant past medical history was admitted to the emergency room with acute ischemic stroke. On his transthoracic echocardiography (TTE), an extremely large thrombus was detected at the apex involving the distal anterior wall. The thrombus was predominantly adherent but with a mobile tip. The patient was subsequently managed with dual antiplatelet therapy. In this report, we present an interesting case of an acute ischemic stroke secondary to a giant left ventricular thrombus in a patient with no past significant cardiac or neurologic medical history. PMID- 29581899 TI - Successful Rotational Atherectomy for an Angulated Calcified Lesion in an Anomalous Right Coronary Artery Using the "Mother-and-Child" Technique. AB - Percutaneous coronary intervention (PCI) involving the anomalous coronary artery is challenging with respect to difficulty in achieving stable catheterization. Rotational atherectomy (RA) can facilitate severely calcified lesions to improve stent delivery and stent expansion; however, its utility in tortuous and angulated coronary arteries is limited with difficulty in delivery of the RA burr. The mother-and-child technique is effective for complex PCIs with increased backup force for device delivery in such complicated cases. We report a case of successful rotational atherectomy using the "mother-and-child" technique with a Dio thrombus aspiration catheter for an angulated calcified lesion in an anomalous origin of the right coronary artery. PMID- 29581897 TI - Baseline mapping of Lassa fever virology, epidemiology and vaccine research and development. AB - Lassa fever (LF) is a zoonotic disease associated with acute and potentially fatal hemorrhagic illness caused by the Lassa virus (LASV), a member of the family Arenaviridae. It is generally assumed that a single infection with LASV will produce life-long protective immunity. This suggests that protective immunity induced by vaccination is an achievable goal and that cell-mediated immunity may play a more important role in protection, at least following natural infection. Seropositive individuals in endemic regions have been shown to have LASV-specific T cells recognizing epitopes for nucleocapsid protein (NP) and glycoprotein precursor (GPC), suggesting that these will be important vaccine immunogens. The role of neutralizing antibodies in protective immunity is still equivocal as recent studies suggest a role for neutralizing antibodies. There is extensive genetic heterogeneity among LASV strains that is of concern in the development of assays to detect and identify all four LASV lineages. Furthermore, the gene disparity may complicate the synthesis of effective vaccines that will provide protection across multiple lineages. Non-human primate models of LASV infection are considered the gold standard for recapitulation of human LF. The most promising vaccine candidates to date are the ML29 (a live attenuated reassortant of Mopeia and LASV), vesicular stomatitis virus (VSV) and vaccinia vectored platforms based on their ability to induce protection following single doses, high rates of survival following challenge, and the use of live virus platforms. To date no LASV vaccine candidates have undergone clinical evaluation. PMID- 29581900 TI - Autotransplantation and Orthodontic Treatment after Maxillary Central Incisor Region Trauma: A 13-Year Follow-Up Case Report Study. AB - The anterior maxilla is the most prone region to the trauma during childhood, and tooth loss sometimes happens due to trauma. Replacing the missing teeth has always been one of the dentists' challenges in children and adolescents, since their dentofacial growth is not complete. Autotransplantation of mandibular premolars with two-thirds or three-quarters of root formation provides the best prognosis for the tooth survival. This case report describes the management of a 10-year-old boy suffering a severe dental injury who received the autotransplantation of the premolars from mandible to restore the space caused by trauma in maxillary central incisor region and a 13-year follow-up of the autotransplantation. PMID- 29581901 TI - Regenerative Endodontic Treatment of a Maxillary Mature Premolar. AB - Regenerative endodontic treatment was performed on a mature maxillary premolar diagnosed as chronic pulpitis. The root canals were chemomechanically prepared and placed intracanal medicaments at the first appointment. Then 2 weeks later, a blood clot was created in the canals, over which mineral trioxide aggregate was placed. At 6-month follow-up, cementum-like tissue seemed to be formed in the root canal along with nearly recovered pulp vitality. At 12-month recall, the radiographic results revealed evidence of root wall thickening. At 30-month recall, no periapical lesion was found. This case report indicates that regenerative endodontic treatment for the mature premolar is feasible. More cases are needed for further validation. PMID- 29581902 TI - Sectional Fixed Orthodontic Extrusion Technique in Management of Teeth with Complicated Crown-Root Fractures: Report of Two Cases. AB - Complicated crown-root fractures account for a small percentage of traumatic dental injuries seen in children; however, management of these injuries can be very challenging to clinicians. Factors such as complexity of the injury, patient's age and dentition stage, patient's cooperation, and parental demands may have some bearing on the type of treatment undertaken and its outcomes. In some children, these injuries may have significant impact on their quality of life. The purpose of this article is to describe two cases of complicated crown root fracture which were successfully managed through orthodontic extrusion using a sectional fixed orthodontic technique. The basis for the treatment technique and its favourable outcomes were highlighted with its advantages and drawbacks. PMID- 29581903 TI - Ingested Foreign Body Migration to the Liver: An Unusual Cause of Persistent Abdominal Pain in a 54-Year-Old Female. AB - Abdominal pain is a common presentation in emergency medicine. We describe the case of a 54-year-old female who presented to the emergency department due to worsening abdominal pain. She had a history of right upper quadrant (RUQ) abdominal pain that had been ongoing for several months. The pain had been thought by the primary care team to be related to gastritis and she had been prescribed a proton pump inhibitor (PPI). Her abdominal pain increased in the three days prior to her presentation to the emergency department (ED). The computed tomography (CT) scan of the abdomen showed a foreign body (FB) in the liver which was successfully removed surgically. Pathology results showed that the FB was consistent with a small bone fragment. Ingestions of FB are common but seldom result in complications. When complications do arise, perforation of a hollow viscous is typically seen. Rarely, transmigration of the FB can occur. PMID- 29581904 TI - Nightmare and Abnormal Dreams: Rare Side Effects of Metformin? AB - Background: Metformin is widely known as an antidiabetic agent which has significant gastrointestinal side effects, but nightmares and abnormal dreams as its adverse reactions are not well reported. Case Presentation: Herein we present a case of 56-year-old male patient with no known history of recurrent nightmares and sleep disorder, experiencing nightmare and abnormal dreams directly after consumption of 750 mg extended release metformin. He reported his dream as an unpleasant experience which awakened him at night with negative feelings. The nightmare only lasted for a night, but his dreams every night thereafter seemed abnormal. The dreams were vivid and indescribable. The disappearance and occurrence of abnormal dreams ensued soon after the drug was discontinued and rechallenged. The case was assessed using Naranjo Adverse Drug Reaction (ADR) probability scale and resulted as probable causality. Conclusion: Metformin might be the underlying cause of nightmare and abnormal dreams in this patient. More studies are needed to confirm the association and causality of this findings. PMID- 29581905 TI - Antiphospholipid Antibody Induced by Nivolumab. AB - Nivolumab is a monoclonal antibody against the programmed death protein 1 and is used for patients with advanced melanoma. It is associated with potentially immune-related adverse events, including disorders of the skin, GI tract, and the thyroid; these disorders were successfully treated with prednisone and infliximab. Other immunotherapeutic agents were observed to induce the formation of antiphospholipid antibody (APA) including alpha-interferon and interleukin-2. We present a case of APA development after the third dose of nivolumab in a 71 year-old male with advanced melanoma. The APA was detected after finding a prolonged aPTT; the lupus anticoagulant assay tested positive. The patient was treated with prednisone but, unfortunately, he expired a few days later. PMID- 29581907 TI - Pregnancy after Prosthetic Aortic Valve Replacement: How Do We Monitor Prosthetic Valvular Function during Pregnancy? AB - Background: With modern medicine, many women after structural heart repair are deciding to experience pregnancy. There is a need for further study to identify normal echocardiographic parameters to better assess prosthetic valvular function in pregnancy. In addition, a multidisciplinary approach is essential in managing pregnant patients with complex cardiac conditions. Case: A 22-year-old nulliparous woman with an aortic valve replacement 18 months prior to her pregnancy presented to prenatal care at 20-week gestation. During her prenatal care, serial echocardiography showed a significant increase in the mean gradient across the prosthetic aortic valve. Multidisciplinary management and a serial echocardiography played an integral role in her care that resulted in a successful spontaneous vaginal delivery without complications. Conclusion: Further characterization of the normal echocardiographic parameters in pregnant patients with prosthetic valves is critical to optimize prenatal care for this patient population. This case report is novel in that serial echocardiograms were obtained throughout prenatal care, which showed significant changes across the prosthetic aortic valve. Teaching Points: (1) Further study is needed to identify normal echocardiographic parameters to best assess prosthetic valvular function in pregnancy. (2) Multidisciplinary management is encouraged to optimize prenatal care for women with prosthetic aortic valve replacements. PMID- 29581906 TI - The Cytoreductive Effect of Radiotherapy for Small Cell Ovarian Carcinoma of the Pulmonary Type: A Case Report and Review of the Literature. AB - Small cell ovarian carcinoma of the pulmonary type is a rare and highly aggressive tumor for which a suitable treatment strategy has not been established. A 45-year-old woman presented with abdominal swelling, and primary ovarian carcinoma was suspected. The postoperative pathological diagnosis was small cell ovarian carcinoma of the pulmonary type. She also had complicated grade 1 endometrioid carcinoma of the uterine corpus. Three courses of cisplatin and etoposide therapy were administered as adjuvant chemotherapy. Because the tumor was chemotherapy resistant, she underwent palliative abdominal irradiation at a dose of 26 Gy in 13 fractions, which induced cytoreduction and provided symptomatic relief. She died 4 months after surgery. Lactate dehydrogenase was a useful tumor marker during treatment. Here, we present an extremely rare case of a patient with small cell ovarian carcinoma of the pulmonary type treated with radiotherapy after surgery and chemotherapy. PMID- 29581908 TI - Sarcomatoid Variant of Urothelial Carcinoma of the Renal Pelvis with Inferior Vena Cava Tumour Thrombus: A Case Report and Literature Review. AB - Sarcomatoid variant of urothelial carcinoma (SVUC) of the renal pelvis is a rare entity. To the best of our knowledge, around 25 cases of this neoplasm have been reported in the literature to date, most of which were of high stage. The inferior vena cava tumour thrombus, which is a hallmark of renal cell carcinoma (RCC), may rarely be found in urothelial carcinoma of renal pelvis. In this report, a case of SVUC associated with tumour extension to inferior vena cava is documented. This association has been encountered in only one previously reported case. The possibility of urothelial carcinoma of the renal pelvis should therefore be included in the differential diagnosis of tumour thrombus of the inferior vena cava. PMID- 29581909 TI - Mechanically induced Ca2+ oscillations in osteocytes release extracellular vesicles and enhance bone formation. AB - The vast osteocytic network is believed to orchestrate bone metabolic activity in response to mechanical stimuli through production of sclerostin, RANKL, and osteoprotegerin (OPG). However, the mechanisms of osteocyte mechanotransduction remain poorly understood. We've previously shown that osteocyte mechanosensitivity is encoded through unique intracellular calcium (Ca2+) dynamics. Here, by simultaneously monitoring Ca2+ and actin dynamics in single cells exposed to fluid shear flow, we detected actin network contractions immediately upon onset of flow-induced Ca2+ transients, which were facilitated by smooth muscle myosin and further confirmed in native osteocytes ex vivo. Actomyosin contractions have been linked to the secretion of extracellular vesicles (EVs), and our studies demonstrate that mechanical stimulation upregulates EV production in osteocytes through immunostaining for the secretory vesicle marker Lysosomal-associated membrane protein 1 (LAMP1) and quantifying EV release in conditioned medium, both of which are blunted when Ca2+ signaling was inhibited by neomycin. Axial tibia compression was used to induce anabolic bone formation responses in mice, revealing upregulated LAMP1 and expected downregulation of sclerostin in vivo. This load-related increase in LAMP1 expression was inhibited in neomycin-injected mice compared to vehicle. Micro computed tomography revealed significant load-related increases in both trabecular bone volume fraction and cortical thickness after two weeks of loading, which were blunted by neomycin treatment. In summary, we found mechanical stimulation of osteocytes activates Ca2+-dependent contractions and enhances the production and release of EVs containing bone regulatory proteins. Further, blocking Ca2+ signaling significantly attenuates adaptation to mechanical loading in vivo, suggesting a critical role for Ca2+-mediated signaling in bone adaptation. PMID- 29581910 TI - Rehabilitation Outcomes for Total Knee Arthroplasties: Continuous Adductor Canal Block Versus Continuous Femoral Nerve Block. AB - Objective: To determine whether any strength, range of motion (ROM), or functional improvement exists in the adductor canal block (ACB) group after completion of inpatient rehabilitation and following the removal of the continuous block. Design: Retrospective cohort. Setting: Inpatient rehabilitation at discharge and outpatient orthopedic clinic for follow-up. Participants: Two hundred forty-six consecutive primary total knee arthroplasties (TKAs; N = 221 patients) performed by a single surgeon in a single institution between July 2013 and August 2015 for a diagnosis of osteoarthritis. Interventions: All TKA cases received a continuous femoral nerve block (FNB) from July 2013 to August 2014 for postoperative pain control. From August 2014 through August 2015, all TKAs received a continuous ACB. Main Outcome Measures: Manual muscle tests (MMTs; 0-5 scale) of the quadriceps and passive ROM of the knee were assessed at 3 time periods (hospital discharge [HD], 1-2 weeks, and 1 month). Patient-oriented outcomes and clinical knee scores were examined preoperatively and postoperatively at 3 and 6 months. Results: 63.6% of FNB cases had an MMT less than 3 at HD and 36.4% of FNB cases had an MMT of 3 or greater at HD. Conversely, 46% of ACB cases had an MMT less than 3 at HD and 54% had an MMT of 3 or greater at HD. There were no statistically significant differences in all postoperative variables at all tested time periods. Conclusions: This study showed no short term postoperative advantages in the ACB group after catheter removal. The superior inpatient rehabilitation course in the continuous ACB group is likely not long enough to translate into any maintained benefit following catheter removal. Nevertheless, the trend toward greater strength in the ACB group in the immediate short term at HD warrants further investigation. PMID- 29581911 TI - Fevers in Adult Lupus Patients. AB - Variability in systemic lupus erythematosus (SLE) disease manifestations is well recognized. Lupus disease activity can range from mild to severe. Fever is a common manifestation of SLE and occurs in 36%-86% of patients. In the Modified Systemic Lupus Erythematosus Disease Activity Index (M-SLEDAI), fever is taken into account as disease activity scoring. Assessment of lupus patients with fever is an important diagnostic challenge, since the initial clinical presentation of a patient with lupus is very similar to the acute febrile phase of an infection. The attribution of fever to SLE holds only after other causes are excluded. PMID- 29581912 TI - Massive Intradural Chondroma Masquerading as Lower Body Parkinsonism. AB - Intracranial chondromas of the dural convexity are exceedingly rare with less than 30 reported in the literature to date. We report a massive intradural convexity chondroma in a patient initially thought to have a frontal gait neurodegenerative disorder. This large tumor required a complex, piecemeal surgical resection due to the dense, fibrous nature of the tumor and the proximity of crucial structures. The patient had complete resolution of her preoperative symptoms after surgical excision. PMID- 29581913 TI - Respiratory Rate Variability as a Prognostic Factor in Hospitalized Patients Transferred to the Intensive Care Unit. AB - Introduction Increasing mortality rates within the intensive care unit (ICU) is an ever growing problem, ultimately leading to increases in the cost of healthcare expenditures. Currently, there are attempts to use guidelines in the hospital setting to predict overall mortality in critically ill patients. However, a predictor of subsequent ICU admissions remains to be explored. Recent data has shown the importance of monitoring respiratory rate variability (RRV) as a useful predictor of the deterioration of patients. Respiratory rate, in comparison to blood pressure or pulse rate, is deemed as the better determinant in identifying high-risk patients. Aim Our study aims to assess the role of RRV monitoring as a potential prognostic marker predictive of ICU admission. Results There was a significant (p = 0.009) increase in RRV between the third and fourth set of respiratory rates prior to ICU admission, such that coefficient of variation percentage (CV%) increased from 0.3% (95% confidence interval (CI): 0.09 - 0.42) to 0.7% (95% CI: 0.04 - 0.9) about 12 hours before admission to the ICU independent from diagnosis. Conclusion Using elevated RRV as a signal may be a useful prognostic tool in providing early intervention, thus reducing the incidence of subsequent morbidity and mortality in patients that might necessitate an ICU admission. PMID- 29581914 TI - Pepto-Bismol Tablets Resembling Foreign Bodies on Abdominal Imaging. AB - A 28-year-old female presented to the emergency department (ED) with a one-day history of severe, diffuse abdominal pain of sudden onset. In the ED, an abdominal x-ray was done, which showed two hyperdense disc-shaped structures. When her abdominal pain did not subside, the ED performed a computerized tomography (CT) scan of the abdomen and pelvis with contrast, which showed the two previously noted 16 mm disc-shaped objects to actually be located within the cecum. Based on the history and imaging, it was deduced that the two discs were likely to be Pepto-Bismol tablets (Proctor & Gamble Co., Cincinnati, OH). Most medications are radiolucent, but there are some that are radiopaque, including Pepto-Bismol (also known as bismuth subsalicylate). While quite a rare occurrence, it is important to know about since it can lead to unnecessary endoscopy and patient anxiety. PMID- 29581915 TI - Four-year Survival (and Counting) after Stereotactic Radiosurgery to Nearly 100 Brain Metastases: A Case Report. AB - Brain metastases are a relatively common consequence of Stage IV melanoma. Historically, patients with brain metastases fare poorly, with median survival of only weeks to months. Patients with multiple metastases in the brain have often been overlooked in the literature, with the focus being placed more on patients with only a small number of metastases. The authors present a case of a 42-year old man with a total of 98 brain metastases treated over several Gamma Knife sessions. He is nearly five years out from his initial treatment. This case highlights the fact that there is a large amount of variability in survival after diagnosis with brain metastases. Selection for treatment should be based on the clinical picture and clinicians should take care to avoid selection bias in this population. PMID- 29581916 TI - Hip Fracture in a Patient with Primary Hyperparathyroidism: Medical and Surgical Lessons. AB - Hyperparathyroidism is a condition which can be primary, secondary or tertiary and is characterized by increased calcium levels, low phosphate levels, and elevated parathyroid hormone (PTH) levels. Primary hyperthyroidism can cause severe bone resorption leading to bone pains and pathological fracture. We present the case of a patient with severe primary hyperparathyroidism with an atraumatic fracture at the neck of the femur and multiple medical comorbidities presenting a surgical challenge. While primary hyperparathyroidism is rare, it should be considered during differential diagnoses. PMID- 29581917 TI - Idiopathic Cutis Verticis Gyrata in a Female. AB - Cutis verticis gyrata (CVG) is a benign proliferation and hypertrophy involving the scalp which exhibits furrows resembling the cerebral cortex convolutions. The diagnosis of CVG is based on clinical findings. Complementary investigations are recommended to rule out local or systemic underlying disorders. Idiopathic or essential primary CVG refers to cases without obvious origin and with no other associated abnormalities. These forms affect mainly men. Herein, the authors present a new observation of an idiopathic CVG in a female, which seems to be extremely rare. PMID- 29581918 TI - Steroids and Thyrotoxicosis Precipitate Periodic Paralysis. AB - Thyrotoxic Periodic Paralysis (TPP) belongs to a group of muscle diseases called channelopathies, which present with painless generalized muscle weakness without exertion. TPP can be precipitated by a large carbohydrate meal, stress, strenuous exercise, alcohol, a high-salt diet, menstruation, and cold temperatures. Rarely, steroids such as dexamethasone can also precipitate a TPP attack. A 29-year-old Hispanic male, with a history of hyperthyroidism, presented to the emergency department with progressive weakness, predominantly in the lower extremities since morning. Earlier that day, the patient was seen in the same emergency department for difficulty in swallowing. He was diagnosed with uvulitis and received intramuscular dexamethasone and was discharged with amoxicillin for ten days. At home, he started to develop cramps in his lower extremities associated with paresthesias, which progressed to severe weakness to the point where he could not get out of bed. He returned to the hospital and revealed that he had suffered a similar episode following a steroid injection five years ago. He had not sought medical attention as it resolved spontaneously. He denied strenuous exercise, carbohydrate-rich meal, or alcohol ingestion. The patient had been noncompliant with atenolol and methimazole for the past month after losing his medical insurance. On examination, the patient appeared alert and calm. His vitals were significant for tachycardia of 123 beats per minute. Thyromegaly and tenderness were absent on examination of the neck. Muscle strength was 5/5 in the ankle dorsiflexors and ankle plantar flexors bilaterally, but the strength of the iliopsoas, quadriceps, and hamstrings was only 2/5 bilaterally. Deep tendon reflexes were diminished throughout to 1+. Laboratory findings were significant for profound hypokalemia, hypophosphatemia, low thyroid stimulating hormone, and elevated free T3 and T4 levels suggestive of hyperthyroidism. His electrolytes were replaced aggressively and his home medications were restarted. His electrolyte imbalance corrected and his symptoms resolved within a day and he was discharged home. The overwhelming majority of TPP cases reported are male patients, hence this case demonstrates the need to be aware of this complication while treating hyperthyroid male patients with steroids. Hyperthyroidism potentiates catecholamine-mediated Na/K ATPase transport of potassium into the cells. Glucocorticoids are used in the treatment of thyroid storm as it prevents the peripheral conversion of T4 to T3. Moreover, glucocorticoids increase glucose levels stimulating insulin release, which shifts potassium intracellularly accentuating muscle weakness. Although the incidence of glucocorticoids causing TPP is low and not many cases are documented, it is still an important condition to be aware of and can have major clinical implications. Clinicians should be aware of this small subset of hyperthyroidism patients where the use of glucocorticoids can precipitate paralysis. PMID- 29581919 TI - Liver Abscesses Caused by Streptococcus intermedius in an Immunocompromised Patient. AB - Streptococcus intermedius is a Gram-positive bacterium that is part of the normal flora in the oral cavity, as well as in the upper respiratory, female urogenital, and gastrointestinal tracts. It may also be found in human feces and is the dominant species found in subgingival plaque. We present a case of a 50-year-old man who came to the emergency room with abdominal pain for weeks associated with nausea and vomiting, diarrhea, and fever. A computed tomography (CT) scan of the abdomen showed numerous cysts throughout the liver. The patient was started on intravenous (IV) antibiotics and fluid from two of the liver abscesses was obtained for culture. PMID- 29581920 TI - First Clinical Applications of a High-Definition Three-Dimensional Exoscope in Pediatric Neurosurgery. AB - The ideal visualization tools in microneurosurgery should provide magnification, illumination, wide fields of view, ergonomics, and unobstructed access to the surgical field. The operative microscope was the predominant innovation in modern neurosurgery. Recently, a high-definition three-dimensional (3D) exoscope was developed. We describe the first applications in pediatric neurosurgery. The VITOM 3D exoscope (Karl Storz GmbH, Tuttlingen, Germany) was used in pediatric microneurosurgical operations, along with an OPMI PENTERO operative microscope (Carl Zeiss AG, Jena, Germany). Experiences were retrospectively evaluated with five-level Likert items regarding ease of preparation, image definition, magnification, illumination, field of view, ergonomics, accessibility of the surgical field, and general user-friendliness. Three operations were performed: supratentorial open biopsy in the supine position, infratentorial brain tumor resection in the park bench position, and myelomeningocele closure in the prone position. While preparation and image definition were rated equal for microscope and exoscope, the microscope's field of view, illumination, and user-friendliness were considered superior, while the advantages of the exoscope were seen in ergonomics and the accessibility of the surgical field. No complications attributed to visualization mode occurred. In our experience, the VITOM 3D exoscope is an innovative visualization tool with advantages over the microscope in ergonomics and the accessibility of the surgical field. However, improvements were deemed necessary with regard to field of view, illumination, and user friendliness. While the debate of a "perfect" visualization modality is influenced by personal preference, this novel visualization device has the potential to become a valuable tool in the neurosurgeon's armamentarium. PMID- 29581921 TI - Posterior Vitreous Detachment Precipitated by Yoga. AB - Yoga has recently been touted as a means to improve physical and mental well being. However, no form of exercise is without its risks. A 32-year-old Chinese female with moderate myopia complained of right eye sudden onset of floaters and mild blurring of vision after the head-down posture. The visual acuity was 6/12 in the right eye and 6/9 in the left eye. A right eye fundus examination showed posterior vitreous detachment, with a small blood clot located at the inferior margin of the optic disc. The patient was diagnosed with right eye vitreous hemorrhage secondary to acute posterior vitreous detachment and was managed conservatively. Acute changes in posture, especially between an upright and a head-down position, may cause acute posterior vitreous detachment. As yoga practitioners may be required to assume this head-down position, myopic patients should be warned of the possible ocular complications of this exercise. PMID- 29581922 TI - A Lymphoma Almost Overlooked. AB - A 50-year-old female with a prolonged history of untreated human immunodeficiency virus (HIV) presented with a large vaginal mass. During workup, the mass was found to be vaginal squamous cell carcinoma. Imaging suggested stage IV disease, but a biopsy of liver lesions demonstrated synchronous diffuse large B-cell lymphoma. Her treatment course was notable for complete remission of her lymphoma with lymphoma-directed chemotherapy and complete clinical response of her squamous cell carcinoma to lymphoma-directed therapy. She tolerated intensive chemotherapy despite her HIV but eventually died due to infectious complications during surgery to address a vaginal fistula. The case is demonstrative of several important diagnostic and therapeutic principles in the management of HIV associated malignancies. Thorough consideration and testing must be performed to ensure accurate staging, as synchronous malignancies and infections can distort standard clinical testing. Further, standard chemotherapeutic regimens often must be tailored and specially sequenced when dealing with severely immunocompromised patients with multiple synchronous processes. PMID- 29581923 TI - Existing Smog in Lahore, Pakistan: An Alarming Public Health Concern. AB - Lahore, the second-largest and most polluted city in Pakistan, has been plagued by a heavy blanket of smog recently. The ever-growing urbanization and industrialization have contributed to the worsening air quality of the city. Smog, being hazardous to health, is leading to a rapid sprout in multiple health related problems, as well as raising concerns about the long-term deleterious effects on public health. The current situation is expected to worsen due to the lack of an active action plan from the government's side and a failure of concerned authorities to take note of the urgency of the situation. Hence, we aim to highlight this pressing issue in the light of previously published articles, to alert the relevant authorities regarding the detrimental consequences smog can have on public health and urge them to take immediate action to avoid further damage. PMID- 29581924 TI - Distinguishing Pediatric Lyme Arthritis of the Hip from Transient Synovitis and Acute Bacterial Septic Arthritis: A Systematic Review and Meta-analysis. AB - Objective Lyme arthritis is an increasingly recognized clinical entity that often prompts orthopaedic evaluation in pediatric patients. While Lyme arthritis is most common in the knee, the clinical presentation of Lyme arthritis of the hip can be similar to both acute bacterial septic arthritis and transient synovitis. Accurately distinguishing these clinical entities is important since the definitive treatment of each is distinct. Because there is limited literature on monoarticular Lyme arthritis of the hip, the purpose of this study was to perform a systematic review and meta-analysis of clinical and laboratory parameters associated with Lyme arthritis (LA) of the hip and compare them to septic arthritis (SA) and transient synovitis (TS). Study design A systematic review of the literature was performed using the following search terms, including the variants and plural counterparts "hip" and "Lyme arthritis." A final database of individual patients was assembled from the published literature and direct author correspondence, when available. A previously published cohort of patients with hip transient synovitis or septic arthritis was used for comparative analysis. A comparative statistical analysis was performed to the assembled database to assess differences in laboratory and clinical variables between the three diagnoses. Results Data on 88 patients diagnosed with Lyme arthritis of the hip was collected and consolidated from the 12 articles meeting inclusion criteria. The average age of patients presenting with Lyme arthritis was 7.5 years (+/- 3.5 years), the mean erythrocyte sedimentation rate (ESR), and the C-reactive protein (CRP) was 41 mm/hr and 3.9 mg/L, respectively. Peripheral white blood cell (WBC) count averaged 10.6 x 109cells/L with the synovial WBC count averaging 55,888 cells/mm3. Compared to a previous cohort of patients with confirmed transient synovitis or septic arthritis, the 95% confidence interval for ESR was 21 - 33 mm/hr in those diagnosed with toxic synovitis (TS), 37 - 46 mm/hr for Lyme arthritis (LA), and 44 - 64 mm/hr for septic arthritis (SA). Synovial WBC counts (cells/mm3) 95% confidence intervals (CI) were 5,644 - 15,388 cells/mm3 for TS, 47,533 - 64,242 cells/mm3 for LA, and 105,432 - 260,214 cells/mm3 for SA. There was a statistically significant difference in the incidence of fever > 38.5oC (P < 0.001) and refusal to bear weight (P < 0.01) between SA, LA, and TS. Conclusions Monoarticular Lyme arthritis can be a cause of hip pain in certain geographic areas and has clinical and diagnostic overlap with transient synovitis and acute bacterial septic arthritis. This study consolidates the available literature and represents the largest series of patients diagnosed with Lyme arthritis of the hip to date. We propose a diagnostic algorithm that serially incorporates ESR, followed by a synovial neutrophil count, when evaluating pediatric patients with an irritable hip in Lyme endemic areas. PMID- 29581925 TI - Isolated Renal Laceration on Point-of-care Ultrasound. AB - We report a renal laceration identified on a point-of-care ultrasound (POCUS) performed in the emergency department on a 58-year-old female presenting after blunt trauma. Emergency workup demonstrated a right flank abrasion with tenderness to palpation, hematuria, and decreasing hematocrit. A Focused Assessment with Sonography in Trauma (FAST) exam, performed as part of the intake trauma protocol, identified positive intraperitoneal fluid in the right upper quadrant. A computed tomography (CT) scan established a diagnosis of isolated right renal hematoma arising from a Grade IV laceration, with no collecting duct involvement. This report reviews the sonographic distinction between a renal hematoma and a positive FAST exam, and emphasizes the vital role ultrasound plays in the evaluation of the trauma patient. PMID- 29581926 TI - Morphine, Oxygen, Nitrates, and Mortality Reducing Pharmacological Treatment for Acute Coronary Syndrome: An Evidence-based Review. AB - Since it was first reported in 1912, acute coronary syndrome (ACS) has become the leading cause of death in the Western world. Several improvements that have been made over the years in the pharmacological treatment of ACS have reduced the relative risk of death due to myocardial infarction from 35-45% previously to approximately 3.5% at present. Universities, websites, and educational videos commonly use a mnemonic for morphine, oxygen, nitrates, and aspirin (MONA) to refer to the adjuvant treatment used for the management of ACS. We review the scientific data pertaining to treatment strategies for the management of ACS and discuss whether MONA remains relevant in the present scenario. While using morphine and oxygen is associated with risks such as higher mortality and increase in the size of the infarct, respectively, several available drugs such as fibrinolytics, anticoagulants, beta-blockers, renin-angiotensin-aldosterone system inhibitors, P2Y12 inhibitors, and statins are known to be useful to treat ACS. MONA should be viewed as an obsolete teaching and learning aid, and therefore we recommend that its use be discontinued for the management of ACS. PMID- 29581929 TI - An efficient method for integration of PCR fragments into adjacent or overlapping restriction sites during gene cloning. AB - In the present work, a simple and straightforward method was developed to clone any PCR-amplified products into restriction sites that are very close, adjacent or overlapping in the expression vector. The novelty of the methodology involves a crucial primer-designing step by adding appropriate overhangs to the 5' ends of primers based on the multiple cloning sites (MCS) (polylinker) region of expression vector. After PCR amplification, actual cloning is performed not in adjacent RE sites, but in sites that are little distant in the MCS. However, the sites lost during this cloning step are maintained intact since they are provided by the cloned PCR product (through the primer overhangs). Gene for green fluorescent protein (GFP) was cloned and expressed employing this strategy to demonstrate its simplicity. This method is highly useful for vector modification without losing the restriction sites present in the MCS. PMID- 29581927 TI - Differential gene expression profiling through transcriptome approach of Saccharum spontaneum L. under low temperature stress reveals genes potentially involved in cold acclimation. AB - Sugarcane (Saccharum sp.) is predominantly grown in both tropics and subtropics in India, and the subtropics alone contribute more than half of sugarcane production. Sugarcane active growth period in subtropics is restricted to 8-9 months mainly due to winter's low temperature stress prevailing during November to February every year. Being a commercial crop, tolerance to low temperature is important in sugarcane improvement programs. Development of cold tolerant sugarcane varieties require a deep knowledge on molecular mechanism naturally adapted by cold tolerant genotypes during low temperature stress. To understand gene regulation under low temperature stress, control and stressed (10 degrees C, 24 h) leaf samples of cold tolerant S. spontaneum IND 00-1037 collected from high altitude region in Arunachal Pradesh were used for transcriptome analysis using the Illumina NextSeq 500 platform with paired-end sequencing method. Raw reads of 5.1 GB (control) and 5.3 GB (stressed) obtained were assembled using trinity and annotated with UNIPROT, KEGG, GO, COG and SUCEST databases, and transcriptome was validated using qRT-PCR. The differential gene expression (DGE) analysis showed that 2583 genes were upregulated and 3302 genes were down regulated upon low temperature stress. A total of 170 cold responsive transcriptional factors belonging to 30 families were differentially regulated. CBF6 (C-binding factor), a DNA binding transcriptional activation protein associated with cold acclimation and freezing tolerance was differentially upregulated. Many low temperature responsive genes involved in various metabolic pathways, viz. cold sensing through membrane fluidity, calcium and lipid signaling genes, MAP kinases, phytohormone signaling and biosynthetic genes, antioxidative enzymes, membrane and cellular stabilizing genes, genes involved in biosynthesis of polyunsaturated fatty acids, chaperones, LEA proteins, soluble sugars, osmoprotectants, lignin and pectin biosynthetic genes were also differentially upregulated. Potential cold responsive genes and transcriptional factors involved in cold tolerance mechanism in cold tolerant S. spontaneum IND 00-1037 were identified. Together, this study provides insights into the cold tolerance to low temperature stress in S. spontaneum, thus opening applications in the genetic improvement of cold stress tolerance in sugarcane. PMID- 29581930 TI - An improved method for rapid analysis of promoters using modified sonication assisted transient assay. AB - We present here a modified, sonication-assisted transient transformation assay for rapid analysis of cis-regulatory elements. We tested promoter elements from MIR159B locus of Brassica juncea by generating stable transgenic lines and compared the transcriptional activity of GUS reporter with that of the transient assay method. To obtain reliable and repeatable results, and to omit false positive data, we optimized several parameters including sonication duration and cycle and concentration of Agrobacterium tumefaciens measured as optical density (O.D.) at 600 nm. To the best of our knowledge, this is the first report of promoter characterization of MIR159B from Brassica juncea, and comparative analysis of stable and transient lines. Our analysis shows that the protocol described herein allows understanding promoter activity/transcriptional control in tissues other than leaf or protoplast which have remained the mainstay for transient analysis thus far. We tested reporter gene GUS under the control of constitutive promoter, CaMV 35S, and MIR159b from Brassica juncea. We optimized the duration of sonication (5-, 10- and 15-min cycle), bacterial density (measured as O.D at 600 nm = 0.6/0.8/1.0) and Agro-infection time (5, 10, 15 min), and co-cultivation (12-, and 24-h). Sonication cycle of 10-min, followed by Agro-infection and co-cultivation with Agrobacterium tumefaciens with O.D. 600 nm = 0.8 and for 12 h was found to be optimum. We could successfully express reporter genes in deep-seated tissues such as floral organs and pollen grains where it was previously not possible to perform transient assay. Constitutive GUS activity was observed when reporter was placed under control of the constitutive promoter of CaMV 35S. Reporter GUS when placed under transcriptional control of MIR159b promoter from Brassica juncea showed reporter activity in floral tissues, in mature pollen grains. Comparative analysis of reporter activity from stable transgenic lines at T2 generation with that of transient assay system reveals identical to near-identical reporter activity. Transient assay could be successfully performed in tissues collected not only from Arabidopsis thaliana, but also from Brassica juncea and Brassica nigra to demonstrate its wide applicability. Our modified method thus has the potential of quick and rapid analysis of promoter activity and allows us to record the developmental dynamics and spatio-temporal expression pattern driven by specific promoters. Suitable modification and controls should also allow analysis of hormonal regulation and identification of trans-factors via DNA-protein interactions. Furthermore, this method can also be extended to study promoters under various environmental conditions that otherwise do not allow growth and complete life cycle of healthy plants and can be modified to test reporter activity in other non-model plants or plants with long life cycle. PMID- 29581932 TI - Enhanced antimicrobial, antioxidant and anticancer activity of Rhizophora apiculata: An experimental report. AB - The present study is designed to evaluate the antimicrobial, antioxidant and anticancer activities of Rhizophora apiculata. Initially, the phenolic and flavonoid content was quantified in solvent extracts, and gallic acid and rutin were used as a control, respectively. Further, antimicrobial and minimal inhibitory activities of different solvent extracts were assessed against human clinical pathogenic bacteria, and the results showed that butanol and methanol extract has potential antimicrobial activity. FTIR analysis of solvent extracts showed the presence of phenolic compounds at 3409-3430 cm-1 that actively involved in various applications including antioxidant and anticancer activities. The in vitro antioxidant activity of solvent extracts showed excellent antioxidant potential, about 84% of DPPH free-radical scavenging, 76% of hydrogen peroxide, 82% of hydroxyl radical scavenging, and 80% of reducing power. Two-way ANOVA analysis showed that the highly significant effect of antioxidant activity depends on the concentration of extracts. The DNA protection efficiency of extracts against oxidative damage was confirmed by DNA nicking assay using bacterial DNA. The methanol extract effectively inhibited the growth and induces the apoptosis through ROS generation and sensitizes the mitochondrial membrane potential of A549 lung cancer cells. Taken together, the results showed that the solvent extracts of R. apiculata could be potential antioxidant and anticancer agents. PMID- 29581931 TI - Pectinolytic enzymes-solid state fermentation, assay methods and applications in fruit juice industries: a review. AB - A plethora of solid substrates, cultivation conditions and enzyme assay methods have been used for efficient production and estimation of polygalacturonase and pectin methylesterase enzymes. Recent developments in industrial biotechnology offer several opportunities for the utilization of low cost agro-industrial waste in Solid State Fermentation (SSF) for the pectinolytic enzyme production using fungi. Fruit waste mainly citrus fruit waste alone and along with other agro industrial waste has been explored in SSF for enzyme production. Agro-industrial waste, due to the economic advantage of low procuring cost has been employed in SSF bioreactors for pectinolytic enzyme production. Acidic pectinases produced by fungi are utilized especially in food industries for clarification of fruit juices. This review focuses on the recent developments in SSF processes utilizing agro-industrial residues for polygalacturonase and pectin methylesterase production, their various assay methods and applications in fruit juice industries. PMID- 29581933 TI - Cervical Stenosis in Adult Arthrogryposis: A Case Report and Review of the Literature. AB - Arthrogryposis multiplex congenita is a rare, nonprogressive congenital disorder that describes a constellation of conditions characterized by multiple joint contractures. Spinal pathology and deformity are common; however, the majority of the literature on arthrogryposis is focused on pediatric management. There exist very few reports on long-term outcomes and management of adults with arthrogryposis. We present a case of cervical spinal stenosis in an adult female with arthrogryposis that underwent posterior cervical decompression and fusion. A review of spine-related sequelae seen in adults with arthrogryposis and considerations for spinal surgery for these patients is discussed. PMID- 29581935 TI - Xpert implementation in challenging scenarios: a brand-new car running on the same bumpy old roads. PMID- 29581934 TI - The Developmental Nature of the Victim-Offender Overlap. AB - Purpose: It is well-established that victims and offenders are often the same people, a phenomenon known as the victim-offender overlap, but the developmental nature of this overlap remains uncertain. In this study, we drew from a developmental theoretical framework to test effects of genetics, individual characteristics, and routine-activity-based risks. Drawing from developmental literature, we additionally tested the effect of an accumulation of adverse childhood experiences (ACEs). Methods: Data came from the Environmental Risk (E Risk) Study, a representative UK birth cohort of 2232 twins born in 1994-1995 and followed to age 18 (with 93% retention). Crime victimization and offending were assessed through self-reports at age 18 (but findings replicated using crime records). We used the classical twin study method to decompose variance in the victim-offender overlap into genetic and environmental components. We used logistic regression to test the effects of childhood risk factors. Results: In contrast to past twin studies, we found that environment (as well as genes) contributed to the victim-offender overlap. Our logistic regression results showed that childhood low self-control and childhood antisocial behavior nearly doubled the odds of becoming a victim-offender, compared to a victim-only or an offender-only. Each additional ACE increased the odds of becoming a victim offender, compared to a victim-only or an offender-only, by approximately 12%, pointing to the importance of cumulative childhood adversity. Conclusions: This study showed that the victim-offender overlap is, at least partially, developmental in nature and predictable from personal childhood characteristics and an accumulation of many adverse childhood experiences. PMID- 29581936 TI - Unsuccessful Xpert(r) MTB/RIF results: the Nigerian experience. AB - Setting: Nigeria, a high tuberculosis (TB) burden country. Objective: To study the rate, distribution and causes of unsuccessful Xpert(r) MTB/RIF test outcomes, with the aim of identifying key areas that need to be strengthened for optimal performance of the assay. Design: This was a retrospective analysis of data uploaded between January and December 2015 from Xpert facilities to the central server using GXAlert. Result: Of 52 219 test results uploaded from 176 Xpert machines, 22.5% were positive for Mycobacterium tuberculosis, 10.8% of which were rifampicin-resistant; 4.7% of the total number of results were invalid, 4.2% had error results and 2.1% no result outcomes. Technical errors were most frequent (69%); these were non-seasonal and occurred in all geopolitical regions and at all health facility levels. Temperature-related errors were more prevalent in the North-West Region, with peaks in April to June. Peak periods for temperature and machine malfunction errors coincided with the periods of low utilisation of the assay. Conclusion: The key challenge affecting performance was poor adherence to standard operating procedures. Periodic refresher training courses, regular supervision, preventive maintenance of Xpert machines and proper storage of cartridges are strategies that could improve Xpert performance. PMID- 29581937 TI - The California Multidrug-Resistant Tuberculosis Consult Service: a partnership of state and local programs. AB - Background: The US Centers for Disease Control and Prevention recommend expert consultation for multi-drug-resistant tuberculosis (MDR-TB) cases. In 2002, the California MDR-TB Service was created to provide expert MDR-TB consultations. We describe the characteristics, treatment outcomes and management of patients referred to the Service. Methods: Surveillance data were used for descriptive analysis of cases, with consultation during July 2002-December 2012. Clinical consultation data and modified World Health Organization indicators were used to assess the care and management of cases, with consultation from January 2009 to December 2012. Results: Of 339 MDR-TB patients, 140 received a consultation. The proportion of patients receiving a consultation increased from 12% in 2002 to 63% in 2012. There were 24 pre-extensively drug-resistant TB and 5 patients with extensively drug-resistant TB. The majority (n = 123, 88%) completed treatment, 5 (4%) died, 7 (5%) moved before treatment completion, 4 (3%) stopped treatment due to an adverse event and 1 (1%) had an unknown outcome. Indicator data showed that 86% underwent rapid molecular drug susceptibility testing, 98% received at least four drugs to which they had known or presumed susceptibility, and 93% culture converted within 6 months. Conclusions: Consultations with the MDR-TB Service increased over time. Results highlight successful treatment and indicator outcomes. PMID- 29581938 TI - Did diabetes mellitus affect treatment outcome in drug-resistant tuberculosis patients in Pakistan from 2010 to 2014? AB - Settings: All hospitals managing drug-resistant tuberculosis (DR-TB) according to national guidelines in Pakistan. Objectives: To assess the effect of diabetes mellitus (DM) and factors associated with unfavourable outcomes in DR-TB. Methods: A cross-sectional study based on a retrospective record review of patients enrolled on DR-TB treatment from 2010 to 2014 in Pakistan. DR-TB data reported to Pakistan's National TB Control Programme on a monthly basis were used for the study. Result: Among 5811 patients enrolled on second-line drugs, 8.8% had DM. Overall, 68.9% had favourable outcomes. No association was found between DM and DR-TB treatment outcomes (risk ratio 0.90, 95%CI 0.74-1.05). Unfavourable outcomes were more frequent among DR-TB patients with human immunodeficiency virus (HIV) co-infection (OR 11.58, 95%CI 2.20-60.72), extensively drug-resistant TB patients (OR 5.36, 95%CI 1.00-28.72), patients with exposure to both first line and second-line anti-tuberculosis drugs (OR 2.45, 95%CI 1.21-4.97) and those with a previous history of treatment in the private sector (OR 1.53, 95%CI 1.16 2.02). Conclusion: Although there were limitations to correctly measuring DM and its management, DM appears not to be a risk factor for unfavourable outcomes in DR-TB patients in our study. DR-TB and HIV co-infection, second-line drug resistance and history of treatment in the private sector were nevertheless more frequently associated with adverse outcomes.

AB - Setting: A southern Myanmar district providing isoniazid preventive therapy (IPT) in one of the last countries to formally recommend it as part of human immunodeficiency virus (HIV) care. Objective: To assess coverage and adherence and the feasibility of IPT scale-up in a routine care setting in Myanmar. Design: A retrospective analysis of people living with HIV (PLHIV) screened for tuberculosis (TB) and enrolled in IPT over a 3-year period (July 2011-June 2014) using clinical databases. Results: Among 3377 patients under HIV care and screened for TB, 2740 (81.1%) initiated IPT, with 2651 (96.8%) completing a 6- or 9-month course of IPT; 83 (3.1%) interrupted treatment for different reasons, including loss to follow-up (n = 41), side effects (n = 15) or drug adherence issues (n = 9); 6 (0.2%) died. Among the IPT patients, 33 (1.2%) were diagnosed with TB, including 9 (0.3%) while on IPT and 24 (0.9%) within 1 year of completion of therapy. Among the PLHIV who completed IPT, one case of isoniazid resistance was detected. Conclusion: Scaling up IPT in Myanmar HIV settings is feasible with high rates of drug adherence and completion, and a low rate of discontinuation due to side effects. IPT scale-up should be prioritised in HIV clinical settings in Myanmar. PMID- 29581941 TI - Can ventilation oust tuberculosis bacilli? Dare to plug the unpluggable. PMID- 29581940 TI - Training social workers to enhance patient-centered care for drug-resistant TB HIV in South Africa. AB - KwaZulu-Natal, South Africa, is the epicenter of an epidemic of drug-resistant tuberculosis (DR-TB) and human immunodeficiency virus (HIV) co-infection, characterized by low rates of medication adherence and retention in care. Social workers may have a unique role to play in improving DR-TB-HIV outcomes. We designed, implemented and evaluated a model-based pilot training course on patient-centered care, treatment literacy in DR-TB and HIV coinfection, patient support group facilitation, and self-care. Ten social workers participated in a 1 day training course. Post-training questionnaire scores showed significant overall gains (P = 0.003). A brief training intervention may be a useful and feasible way to engage social workers in patient-centered care for DR-TB and HIV coinfection.

PMID- 29581944 TI - Osseous changes in the temporomandibular joint in rheumatoid arthritis: A cone beam computed tomography study. AB - Purpose: To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. Materials and Methods: This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled to undergo CBCT imaging for the diagnosis of a complaint not related to or affecting the TMJ. The Fonseca's questionnaire was used to assess the severity of TMJ dysfunction. Rheumatoid factor (RF) and the erythrocyte sedimentation rate (ESR) were assessed in the RA patients. CBCT was then performed in all subjects and osseous TMJ abnormalities were assessed. Results: According to the Fonseca's questionnaire, 14.3% of the patients had no TMJ dysfunction, while 50%, 21.4%, and 14.3% had mild, moderate, and severe dysfunction, respectively. RF was positive in 64.3% of patients, and the ESR level was high in 100%. Imaging findings revealed a statistically significantly higher prevalence of erosion (85.7%), flattening (89.3%), osteophyte formation (32.1%), subchondral cyst (32.1%), sclerosis (64.3%), and condylar irregularities (28.6%) in the RA patients than in the controls. No correlations were found between CBCT findings and the clinical findings, the severity of TMJ dysfunction, disease duration, or laboratory results. Conclusion: RA patients might show extensive osseous abnormalities with no/mild clinical signs or symptoms of TMJ dysfunction that necessitate TMJ imaging for these patients. CBCT is a valuable and efficient modality that can assess osseous TMJ changes in RA patients. PMID- 29581945 TI - Diagnostic accuracy of cone-beam computed tomography scans with high- and low resolution modes for the detection of root perforations. AB - Purpose: This study compared the diagnostic accuracy of cone-beam computed tomography (CBCT) scans obtained with 2 CBCT systems with high- and low resolution modes for the detection of root perforations in endodontically treated mandibular molars. Materials and Methods: The root canals of 72 mandibular molars were cleaned and shaped. Perforations measuring 0.2, 0.3, and 0.4 mm in diameter were created at the furcation area of 48 roots, simulating strip perforations, or on the external surfaces of 48 roots, simulating root perforations. Forty-eight roots remained intact (control group). The roots were filled using gutta-percha (Gapadent, Tianjin, China) and AH26 sealer (Dentsply Maillefer, Ballaigues, Switzerland). The CBCT scans were obtained using the NewTom 3G (QR srl, Verona, Italy) and Cranex 3D (Soredex, Helsinki, Finland) CBCT systems in high- and low resolution modes, and were evaluated by 2 observers. The chi-square test was used to assess the nominal variables. Results: In strip perforations, the accuracies of low- and high-resolution modes were 75% and 83% for NewTom 3G and 67% and 69% for Cranex 3D. In root perforations, the accuracies of low- and high-resolution modes were 79% and 83% for NewTom 3G and was 56% and 73% for Cranex 3D. Conclusion: The accuracy of the 2 CBCT systems was different for the detection of strip and root perforations. The Cranex 3D had non-significantly higher accuracy than the NewTom 3G. In both scanners, the high-resolution mode yielded significantly higher accuracy than the low-resolution mode. The diagnostic accuracy of CBCT scans was not affected by the perforation diameter. PMID- 29581946 TI - Estimation of the effective dose of dental cone-beam computed tomography using personal computer-based Monte Carlo software. AB - Purpose: To calculate the effective doses of cone-beam computed tomography (CBCT) using personal computer-based Monte Carlo (PCXMC) software (Radiation and Nuclear Safety Authority, Helsinki, Finland) and to compare the calculated effective doses with those measured using thermoluminescent dosimeters (TLDs) and an anthropomorphic phantom. Materials and Methods: An Alphard VEGA CBCT scanner (Asahi Roentgen Ind. Co., Kyoto, Japan) with multiple fields of view (FOVs) was used for this study. The effective doses of the scout and main projections of CBCT using 1 large and 2 medium FOVs with a height >10 cm were calculated using PCXMC and PCXMCRotation software and then were compared with the doses obtained using TLD-100 LiF and an anthropomorphic adult human male phantom. Furthermore, it was described how to determine the reference points on the Y- and Z-axes in PCXMC, the important dose-determining factors in this software. Results: The effective doses at CBCT for 1 large (20.0 cm*17.9 cm) and 2 medium FOVs (15.4 cm*15.4 cm and 10.2 cm*10.2 cm) calculated by the PCXMC software were 181, 300, and 158 uSv, respectively. These values were comparable (16%-18% smaller) to those obtained through TLD measurements in each mode. Conclusion: The use of PCXMC software could be an alternative to the TLD measurement method for effective dose estimation in CBCT with large and medium FOVs. PMID- 29581947 TI - Effect of field-of-view size on gray values derived from cone-beam computed tomography compared with the Hounsfield unit values from multidetector computed tomography scans. AB - Purpose: This study aimed to evaluate the effect of field-of-view (FOV) size on the gray values derived from conebeam computed tomography (CBCT) compared with the Hounsfield unit values from multidetector computed tomography (MDCT) scans as the gold standard. Materials and Methods: A radiographic phantom was designed with 4 acrylic cylinders. One cylinder was filled with distilled water, and the other 3 were filled with 3 types of bone substitute: namely, Nanobone, Cenobone, and Cerabone. The phantom was scanned with 2 CBCT systems using 2 different FOV sizes, and 1 MDCT system was used as the gold standard. The mean gray values (MGVs) of each cylinder were calculated in each imaging protocol. Results: In both CBCT systems, significant differences were noted in the MGVs of all materials between the 2 FOV sizes (P<.05) except for Cerabone in the Cranex3D system. Significant differences were found in the MGVs of each material compared with the others in both FOV sizes for each CBCT system. No significant difference was seen between the Cranex3D CBCT system and the MDCT system in the MGVs of bone substitutes on images obtained with a small FOV. Conclusion: The size of the FOV significantly changed the MGVs of all bone substitutes, except for Cerabone in the Cranex3D system. Both CBCT systems had the ability to distinguish the 3 types of bone substitutes based on a comparison of their MGVs. The Cranex3D CBCT system used with a small FOV had a significant correlation with MDCT results. PMID- 29581948 TI - Metal artifact production and reduction in CBCT with different numbers of basis images. AB - Purpose: To evaluate the effect of different numbers of basis images and the use of metal artifact reduction (MAR) on the production and reduction of artifacts in cone-beam computed tomography images. Materials and Methods: An acrylic resin phantom with a metal alloy sample was scanned, with 450 or 720 basis images and with or without MAR. Standard deviation values for the test areas (around the metal object) were obtained as a way of measuring artifact production. Two-way analysis of variance was used with a 5% significance level. Results: There was no significant difference in artifact production among the images obtained with different numbers of basis images without MAR (P=.985). MAR significantly reduced artifact production in the test areas only in the protocol using 720 basis images (P=.017). The protocol using 450 basis images with MAR showed no significant difference in artifact production when compared to the protocol using 720 basis images with MAR (P=.579). Conclusion: Protocols with a smaller number of basis images and with MAR activated are preferable for minimizing artifact production in tomographic images without exposing the patient to a greater radiation dose. PMID- 29581949 TI - Strain elastography of tongue carcinoma using intraoral ultrasonography: A preliminary study to characterize normal tissues and lesions. AB - Purpose: The aim of this study was to evaluate the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography. Materials and Methods: Two patients with squamous cell carcinoma (SCC) who underwent quantitative strain elastography for the diagnosis of tongue lesions using intraoral ultrasonography were included in this prospective study. Strain elastography was performed using a linear 14 MHz transducer (Aplio 300; Canon Medical Systems, Otawara, Japan). Manual light compression and decompression of the tongue by the transducer was performed to achieve optimal and consistent color coding. The variation in tissue strain over time caused by the compression exerted using the probe was displayed as a strain graph. The integrated strain elastography software allowed the operator to place circular regions of interest (ROIs) of various diameters within the elastography window, and automatically displayed quantitative strain (%) for each ROI. Quantitative indices of the strain (%) were measured for normal tissues and lesions in the tongue. Results: The average strain of normal tissue and tongue SCC in a 50-year-old man was 1.468% and 0.000%, respectively. The average strain of normal tissue and tongue SCC in a 59-year-old man was 1.007% and 0.000%, respectively. Conclusion: We investigated the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography. Strain elastography using intraoral ultrasonography is a promising technique for characterizing and differentiating normal tissues and SCC in the tongue. PMID- 29581950 TI - Quantitative evaluation of palatal bone thickness in patients with normal and open vertical skeletal configurations using cone-beam computed tomography. AB - Purpose: To perform a comparative analysis of the palatal bone thickness in Thai patients exhibiting class I malocclusion according to whether they exhibited a normal or open vertical skeletal configuration using cone-beam computed tomography (CBCT). Materials and Methods: Thirty CBCT images of Thai orthodontic patients (15-30 years of age) exhibiting class I malocclusion with a normal or open vertical skeletal configuration were selected. Palatal bone thickness was measured in a 3.0-mm grid pattern on both the right and left sides. The palatal bone thickness of the normal-bite and open-bite groups was compared using the independent t-test. The level of significance was established at P<.05. Results: The palatal bone thickness in the normal-bite group ranged from 2.2+/-1.0 mm to 12.6+/-4.1 mm. The palatal bone thickness in the open-bite group ranged from 1.9+/-1.1 mm to 13.2+/-2.3 mm. The palatal bone thickness was lower at almost all sites in patients with open bite than in those with normal bite. Significant differences were found at almost all anteroposterior sites along the 3 most medial sections (3.0, 6.0, and 9.0 mm lateral to the midsagittal plane) (P<.05). Conclusion: Class I malocclusion with open vertical skeletal configuration may affect palatal bone thickness, so the placement of temporary anchorage devices or miniscrew implants in the palatal area in such patients should be performed with caution. PMID- 29581951 TI - Unusual malignant neoplasms occurring around dental implants: A report of 2 cases. AB - Osseointegrated implants are now commonplace in contemporary dentistry. However, a number of complications can occur around dental implants, including peri implantitis, maxillary sinusitis, osteomyelitis, and neoplasms. There have been several reports of a malignant neoplasm occurring adjacent to a dental implant. In this report, we describe 2 such cases. One case was that of a 75-year-old man with no previous history of malignant disease who developed a solitary plasmacytoma around a dental implant in the left posterior mandible, and the other was that of a 43-year-old man who was diagnosed with squamous cell carcinoma adjacent to a dental implant in the right posterior mandible. Our experiences with these 2 cases suggest the possibility of a relationship between implant treatment and an inflammatory cofactor that might increase the risk of development of a malignant neoplasm. PMID- 29581952 TI - Fractured styloid process masquerading as neck pain: Cone-beam computed tomography investigation and review of the literature. AB - Historically, Eagle syndrome is a term that has been used to describe radiating pain in the orofacial region, foreign body sensation, and/or dysphagia due to a unilateral or bilateral elongated styloid process impinging upon the tonsillar region. Because elongated styloid processes-with or without associated Eagle syndrome-can present with various symptoms and radiographic findings, it can be challenging for healthcare practitioners to formulate an accurate diagnosis. Abnormal styloid anatomy can lead to a multitude of symptoms, including chronic orofacial/neck pain, thus masquerading as more commonly diagnosed conditions. In this report, we describe a patient who presented to our department with styloid process elongation and fracture. A careful history, physical examination, and a conebeam computed tomography (CBCT) investigation led to the diagnosis. The patient was then referred for appropriate care. This case report demonstrates the utilization of CBCT in differentiating a fracture site from a pseudo-joint that might mimic a fracture. PMID- 29581953 TI - Organized hematoma of temporomandibular joint. AB - Organized hematoma is a pseudo-tumorous lesion mostly occurs at sinonasal cavity and often confused with malignant neoplasm. The initiation of this lesion is blood accumulation, probably due to trauma, and this hematoma develops into organized hematoma as it encapsulated with fibrous band and neo-vascularized. Since it is uninformed at temporomandibular joint (TMJ) region, imaging diagnosis might be challenging. Also, delayed detection of mass involving TMJ is not uncommon due to confusion with joint disorder. Thus, this report introduced the rare pathology, organized hematoma on TMJ with advanced imaging features. Also, diagnostic point for early detection was described for the TMJ tumors and pseudo tumors considering complexity of surgical intervention in this region. PMID- 29581954 TI - Influence of Altered Gut Microbiota Composition on Aging and Aging-Related Diseases. AB - The gut microbiota forms a large community that coexists with all species, including humans and rodents. Genome projects have been conducted by many researchers in nearly every country to better understand and treat diseases that lead to death in humans. However, the gut microbiota is known as a "second genome" because it includes microbes, genomic DNA, proteins, and metabolites. A large number of studies have revealed the importance of the gut microbiota. In elderly people, the diversity of the gut microbiota is reduced and there is an increased incidence of degenerative diseases, including Alzheimer's and Parkinson's, and decreased cognitive and memory functions. However, the administration of pre/probiotics can help to improve the symptoms of these diseases. Therefore, we believe that the gut microbiota is important for maintaining homeostasis and diversity, as well as for avoiding gastrointestinal tract-derived diseases and improving health in the elderly population. PMID- 29581955 TI - Effects of Sedentary Behavior, Physical Activity, Frequency of Protein Consumption, Lower Extremity Strength and Lean Mass on All-Cause Mortality. AB - Background: No study has evaluated the potential independent and cumulative effects of physical activity, sedentary behavior, daily frequency of protein consumption, lean mass and muscular strength on mortality risk. Methods: Data from the 1999-2002 NHANES were utilized (N = 1,079 adults 50-85 yr), with follow up through 2011. Leg lean mass was estimated from DXA scans. Knee extensor strength was assessed using the Kin Com MP dynamometer. Physical activity and sedentary behavior were assessed via questionnaire, with the number of meals/day of >=30 g of protein/meal assessed via a "multiple pass" 24-hour dietary interview. An index score was created (range = 0-5) indicating the number of these health characteristics each participant had. Results: Only less sedentary behavior was independently associated with reduced mortality risk (HRadjustment = 0.46; 0.32-0.66). After adjustments, and compared to those with an index score of 0, those with an index score of 1, 2 and 3+, respectively, had a 34%, 49%, and 57% reduced risk of all-cause mortality. Conclusion: While considering physical activity, sedentary behavior, daily protein frequency consumption, lean mass and muscular strength, only sedentary behavior was independently associated with mortality risk among older adults. PMID- 29581956 TI - Effects of Lifestyle on Muscle Strength in a Healthy Danish Population. AB - Background: Lifestyle is expected to influence muscle strength. This study aimed at assessing a possible relationship between smoking, alcohol intake and physical activity, and muscle strength in a healthy Danish population aged 20-79 years. Population study based on data collected from The Copenhagen City Heart Study (CCHS) and measurements of Isokinetic muscle strength from a sub-study of randomly selected healthy participants from CCHS. Methods: 126 women and 63 men were studied. All participants completed a questionnaire regarding their lifestyle, including physical activity, alcohol intake and smoking habits. Isokinetic muscle strength was measured over the upper extremities (UE), trunk, and lower extremities (LE). Multivariate analyses including all of the variables were carried out. Results: The level of daily physical activity during leisure was positively correlated to muscle strength in the lower extremities (p = 0.03) for women, and lower extremities (p = 0.03) and trunk (p = 0.007) for men. Alcohol Intake was in general not correlated to muscle strength. No clear effect of smoking was seen on muscle strength. Conclusion: Our results show that physical activity during leisure is associated with a positive effect on muscle strength in both sexes. When keeping alcohol intake within the recommended limits, alcohol does not seem to affect muscle strength negatively. No effect of smoking on muscle strength was found in our group of healthy subjects. The findings are of importance when considering recommendation on life style when wishing to keeping fit with age to be able to carry out daily activities. PMID- 29581957 TI - Impact of Spiritual Behavior on Self-Reported Illness: A Cross-Sectional Study among Women in the Kailali District of Nepal. AB - Background: Different health behaviors influence health and illness. Spiritual well-being is one of the most important aspects of health promotion. The aim of this study was to identify the association between spiritual behavior in relation to meditation, worship, and physical exercise during yoga with self-reported disease/illness among women of the Kailali district of Nepal. Methods: This was a cross-sectional study with 453 randomly selected women in the Kailali district of Nepal within 1 municipality and 4 village development committees (VDC) using cluster sampling. We used a semi-structured interview to collect the data for selected respondents. Socioeconomics, lifestyle, self-care, and spiritual behavior variables were independent variables, and self-reported illness in the past year was a dependent variable. Descriptive statistics, chi square, hierarchical logistic regression for odds ratio, and 95% CI were used when appropriate. Results: Study results showed that 89% of participants were from the rural area, 29.3% were housewives, 51.4% had no formal education, 43.2% used tobacco, 42.1% did yoga, and 16.9% engaged in regular worship. Self-reported illness was associated with safe toilet-using behavior, tobacco use, junk food consumption, yoga and regular exercise, worship, and regular sleeping habits. Comparing odds ratios and 95% CIs, the women who had safe toilet behavior and did not use tobacco were 2.48 (1.98-7.98) and 2.86 (1.74-7.34) times less likely to be ill, respectively. Likewise, women who consumed junk food; did not regularly exercise, meditate, or worship; and had irregular sleeping habits were 1.65 (1.32 4.61), 2.81(1.91-5.62), 2.56 (2.01-4.88), 4.56 (3.91-8.26), and 2.45 (2.12-5.03) times more likely to become ill, respectively. Conclusion: Our study concludes that spiritual behavior is effective for better health and low risk for disease occurrence. A spiritual health policy and separate curriculum for basic education and medical education should be promoted globally, and further research is recommended. PMID- 29581958 TI - Effects of Different Types of Smoking Cessation Treatments for South Korean Adult Smokers without an Intention to Quit. AB - Background: While there are many different ways to quit smoking, current methods are not equally successful. The objective of this study was to analyze the effects of different types of stop smoking treatment for South Korean adult smokers without an intention to quit. Methods: This cross-sectional study used data of 14,174 adults (age 19 years and over) from the Korea national health and nutrition examination survey (2007-2012) who have experience of smoking. The data were analyzed using multiple logistic regression. Results: According to multiple logistic regression analysis, the education and counseling plus prescription drug group (OR = 14.831, 95% CI = 1.256 to 175.136) and education and counseling plus NRT group (OR = 3.060, 95% CI = 1.971 to 4.748) were associated with increased odds of quitting success compared to the no intervention group. Second, the education and counseling group was associated with increased odds of quitting success compared to the no intervention group (OR = 4.944, 95% CI = 3.463 to 7.058). Third, education and counseling plus NRT (OR = 0.325, 95% CI = 0.161 to 0.657) and NRT alone (OR = 0.322, 95% CI = 0.175 to 0.593) were associated with decreased odds of quitting success compared to the group using prescription drug only. Conclusion: These findings suggest that an approach utilizing education and counseling plus prescription drugs is the most successful type of stop smoking treatment for South Korean adult smokers without an intention to quit. PMID- 29581959 TI - Sleep Quality and Nutritional Intake in Subjects with Sleep Issues According to Perceived Stress Levels. AB - Background: Sleep disorders can negatively affect quality of life with reduced cognitive function. Since stress and eating behavior are considered crucial factors for sleep, this study's aim was to compare objective quality of sleep and nutrition between subjects with sleep issues and different stress levels. Methods: The investigation was performed in adults (>=18 years old) in the Sleep Laboratory between September 2015 and February 2016. Several measurement instruments were utilized, including the Pittsburgh Sleep Quality Index (PSQI), the Korean version of the Brief Encounter Psychosocial Instrument (BEPSI-K), polysomnography, and a food frequency questionnaire (FFQ). Results: There were no statistical differences in demographic data between the lower and higher stress groups except age, which was adjusted. Sleep quality in the lower stress group was better than the higher stress group in terms of sleep efficiency (90.92 +/- 7.72 vs 85.36 +/- 10.25%), sleep latency (16.94 +/- 20.86 vs 9.42 +/- 8.24 min), and WASO result (26 +/- 26.13 vs 43.66 +/- 41.32 min). There were statistically significant differences in nutritional intake between the groups: the lower stress group consumed more vegetables than the higher stress group while the higher stress group consumed more grains, meat and eggs, soju, and coffee products than the lower stress group. Conclusion: This study found that stress level and food intake have significant associations with objective sleep quality. Food and stress management for insomnia should be considered for improving not only quantity but also quality of sleep. PMID- 29581960 TI - Identification of Wheat Inflorescence Development-Related Genes Using a Comparative Transcriptomics Approach. AB - Inflorescence represents the highly specialized plant tissue producing the grains. Although key genes regulating flower initiation and development are conserved, the mechanism regulating fertility is still not well explained. To identify genes and gene network underlying inflorescence morphology and fertility of bread wheat, expressed sequence tags (ESTs) from different tissues were analyzed using a comparative transcriptomics approach. Based on statistical comparison of EST frequencies of individual genes in EST pools representing different tissues and verification with RT-PCR and RNA-seq data, 170 genes of 59 gene sets predominantly expressed in the inflorescence were obtained. Nearly one third of the gene sets displayed differentiated expression profiles in terms of their subgenome orthologs. The identified genes, most of which were predominantly expressed in anthers, encode proteins involved in wheat floral identity determination, anther and pollen development, pollen-pistil interaction, and others. Particularly, 25 annotated gene sets are associated with pollen wall formation, of which 18 encode enzymes or proteins participating in lipid metabolic pathway, including fatty acid omega-hydroxylation, alkane and fatty alcohol biosynthesis, and glycerophospholipid metabolism. We showed that the comparative transcriptomics approach was effective in identifying genes for reproductive development and found that lipid metabolism was particularly active in wheat anthers. PMID- 29581961 TI - Hospitalization Trends in Adult Patients with COPD and Other Respiratory Diseases in Northeast China from 2005 to 2015. AB - Chronic obstructive pulmonary disease (COPD), pneumonia, asthma, and lung cancer are four common respiratory diseases that impose a substantial economic burden on both patients and government in China. The objective of our study is to analyze the temporal trends of several clinical tracking metrics for hospitalization regarding these diseases. Hospital discharge data of 54 hospitals for the period 2005-2015 were derived from the Health and Family Planning Commission in Northeast China. The age-adjusted rate of discharge for the four respiratory diseases increased significantly (COPD, pneumonia, asthma: P trend < .001; lung cancer: P trend = .046). The mean LOS for the four diseases all showed a significant decline (P trend < .001), whereas the mean charge per stay and aggregate charge followed an upward trend over time (P trend < .001). There was a clear upward trend for the readmission rate for asthma patients (P trend = .001), while the trend for COPD patients was unclear (P trend = .224). Age adjusted discharge rates, LOS, and charges for hospitalization regarding several common respiratory diseases in China showed different patterns of change over the past decade. Our results should aid government and administrators in making informed decisions about the management and treatment of respiratory diseases. PMID- 29581962 TI - Protein Kinase G Induces an Immune Response in Cows Exposed to Mycobacterium avium Subsp. paratuberculosis. AB - To establish infection, pathogens secrete virulence factors, such as protein kinases and phosphatases, to modulate the signal transduction pathways used by host cells to initiate immune response. The protein MAP3893c is annotated in the genome sequence of Mycobacterium avium subspecies paratuberculosis (MAP), the causative agent of Johne's disease, as the serine/threonine protein kinase G (PknG). In this work, we report that PknG is a functional kinase that is secreted within macrophages at early stages of infection. The antigen is able to induce an immune response from cattle exposed to MAP in the form of interferon gamma production after stimulation of whole blood with PknG. These findings suggest that PknG may contribute to the pathogenesis of MAP by phosphorylating macrophage signalling and/or adaptor molecules as observed with other pathogenic mycobacterial species. PMID- 29581963 TI - Current Knowledge and Recent Advances of Right Ventricular Molecular Biology and Metabolism from Congenital Heart Disease to Chronic Pulmonary Hypertension. AB - Studies about pulmonary hypertension and congenital heart diseases have introduced the concept of right ventricular remodeling leading these pathologies to a similar outcome: right ventricular failure. However right ventricular remodeling is also a physiological process that enables the normal fetal right ventricle to adapt at birth and gain its adult phenotype. The healthy mature right ventricle is exposed to low pulmonary vascular resistances and is compliant. However, in the setting of chronic pressure overload, as in pulmonary hypertension, or volume overload, as in congenital heart diseases, the right ventricle reverts back to a fetal phenotype to sustain its function. Mechanisms include angiogenic changes and concomitant increased metabolic activity to maintain energy production. Eventually, the remodeled right ventricle cannot resist the increased afterload, leading to right ventricular failure. After comparing the fetal and adult healthy right ventricles, we sought to review the main metabolic and cellular changes occurring in the setting of PH and CHD. Their association with RV function and potential impact on clinical practice will also be discussed. PMID- 29581964 TI - Age Is Not a Limiting Factor in Interventional Radiotherapy (Brachytherapy) for Patients with Localized Cancer. AB - This review examines the role of interventional radiotherapy (IRT otherwise known as brachytherapy) in cancer treatment for elderly patients. Despite their advanced age and associated comorbidities, elderly patients should receive definitive cancer therapies, including surgery and radiotherapy (RT). In fact, RT becomes first-line option for patients who are not eligible for surgery (due to comorbidities, anticoagulant drugs, and risk of disfigurement) or those who refuse it. It emerged from this review of the literature as effective, simple, safe, and comfortable and was associated with good local control, low toxicity rates, and excellent cosmesis and provided a cost benefit. IRT may be used as sole treatment for small cancers or as a useful adjunct to surgery or external beam radiotherapy (EBRT) in more advanced (or lymph node positive) cases, especially when the aim is local control with adequate preservation of normal tissue function. As palliative treatment, IRT preserves quality of life and/or improves survival. It is to be hoped that this review will serve as a helpful guide for members of multidisciplinary teams that are involved in treating elderly patients with cancer. PMID- 29581965 TI - Involvement of Cholinergic Dysfunction and Oxidative Damage in the Effects of Simulated Weightlessness on Learning and Memory in Rats. AB - The present study aimed to determine how the learning and memory gradually change with the prolonged hindlimb unloading (HU) treatment in rats. Different HU durations (7 d, 14 d, 21 d, and 28 d) in Sprague-Dawley (SD) rats were implemented. Cognitive function was assessed using the Morris water maze (MWM) and the shuttle box test. Additionally, parameters about cholinergic activity and oxidative stress were tested. Results showed that longer-than-14 d HU led to the inferior performances in the behavioral tasks. Besides, acetylcholine esterase (AChE) activity, malondialdehyde (MDA) level in brain, reactive oxygen species (ROS), and 8-hydroxy-2-deoxyguanosine (8-OHdG) concentrations of HU rats were significantly increased. Furthermore, choline acetyltransferase (ChAT), superoxide dismutase (SOD), and catalase (CAT) activity in brain were notably attenuated. Most of these effects were more pronounced after longer exposure (21 d and 28 d) to HU, although some indicators had their own characteristics of change. These results indicate that cholinergic dysfunction and oxidative damage were involved in the learning and memory impairments induced by longer-than-14 d HU. Moreover, the negative effects of HU tend to be augmented as the HU duration becomes longer. The results may be helpful to present possible biochemical targets for countermeasures development regarding the memory deficits under extreme environmental conditions. PMID- 29581966 TI - Impaired Gut Epithelial Tight Junction Expression in Hemodialysis Patients Complicated with Intradialytic Hypotension. AB - Background: There is accumulating evidence pointing to uremia-induced impairment of the intestinal epithelial barrier structure in advanced chronic kidney disease (CKD) and hemodialysis (HD) patients. In this study, the impact of intradialytic hypotension on intestinal barrier integrity is being explored. Methods: Immunohistochemical staining was used to detect the expression of 4 types of tight junction (TJ) proteins such as occludin, zonula occludens-1 (ZO-1), claudin 1, and claudin-4, in colonic samples of a group of patients receiving segmental colectomy. Five patients with nondialysis CKD (group 2), 5 HD patients with intradialytic hypotension (group 3), and 5 non-CKD subjects (group 1) were examined. Results: Both patients' groups 2 and 3 demonstrated significantly reduced expression of occludin as compared to group 1 (p < 0.05 and p < 0.01, resp.). Except for claudin-4, expression of all markers of TJ proteins was significantly reduced in patients' group 3 as compared to control (p < 0.01). In addition, decreased expressions of claudin-1 and ZO-1 were also more pronounced in group 3 when compared to group 2. Conclusions: This study extends the earlier finding by demonstrating that dialysis-related hypotension caused even marked depletion of the key protein constituents of the epithelial TJ. PMID- 29581968 TI - A Risk Stratification Model for Lung Cancer Based on Gene Coexpression Network and Deep Learning. AB - Risk stratification model for lung cancer with gene expression profile is of great interest. Instead of previous models based on individual prognostic genes, we aimed to develop a novel system-level risk stratification model for lung adenocarcinoma based on gene coexpression network. Using multiple microarray, gene coexpression network analysis was performed to identify survival-related networks. A deep learning based risk stratification model was constructed with representative genes of these networks. The model was validated in two test sets. Survival analysis was performed using the output of the model to evaluate whether it could predict patients' survival independent of clinicopathological variables. Five networks were significantly associated with patients' survival. Considering prognostic significance and representativeness, genes of the two survival-related networks were selected for input of the model. The output of the model was significantly associated with patients' survival in two test sets and training set (p < 0.00001, p < 0.0001 and p = 0.02 for training and test sets 1 and 2, resp.). In multivariate analyses, the model was associated with patients' prognosis independent of other clinicopathological features. Our study presents a new perspective on incorporating gene coexpression networks into the gene expression signature and clinical application of deep learning in genomic data science for prognosis prediction. PMID- 29581967 TI - Criterion-Related Validity of a Simple Muscle Strength Test to Assess Whole Body Muscle Strength in Chinese Children Aged 10 to 12 Years. AB - Objective: To study the criterion-related validity of simple muscle strength test (SMST) indicators and assess whole body muscle strength in Chinese children aged 10 to 12 years old. Methods: Two hundred and forty children were equally divided into four groups in different genders and residences. The SMST indicators (hand grip, knee bent push-up, back muscle strength, sit-up, leg muscle strength, and standing long jump) were tested. We set up the total level of the whole-body muscle strength (Ftotal) through testing isokinetic muscle strength of the six joints' flexion and extension movements. Pearson correlation analyses were used to analyze the correlation between the SMST indicators and the Ftotal. Results: (1) Leg muscle strength and back muscle strength demonstrated the highest validity scores. Sit-ups, hand grip, and standing long jump demonstrated the lowest validity scores. (2) Leg muscle strength had the highest validity for males, but back muscle strength had the highest validity for females. Conclusions: Back muscle strength and leg muscle strength can give the highest validity of assessing whole body muscle strength, and also has higher validity in both the urban and rural children. For urban children, but not rural, the knee bent push-up also has a high validity indicator. PMID- 29581969 TI - Analgesic Effect of Extracorporeal Shock Wave Treatment Combined with Fascial Manipulation Theory for Adhesive Capsulitis of the Shoulder: A Retrospective Study. AB - Objectives: This study aims to explore whether extracorporeal shockwave treatment (ESWT) based on the theory of fascial manipulation (FM) at select treatment points is superior to traditional local ESWT for pain relief in adhesive capsulitis of the shoulder. Methods: Data from patients with adhesive capsulitis of the shoulder who received weekly ESWT according to fascial manipulation theory (ESWT-FM) or local extracorporeal shockwave treatment (L-ESWT) during a 5-week treatment period were evaluated. Pain-on-movement numeric rating scale (p-NRS) and range of motion (ROM) testing were performed before the treatment period, after the first treatment, and after the fifth treatment. Results: There were significant reductions in pain scores in the ESWT-FM group (p < 0.05) after the first treatment, and after the fifth treatment, both groups had marked, significant improvement (p < 0.05), with a significantly greater reduction in pain (p-NRS) in the ESWT-FM group compared to the L-ESWT group (p < 0.05). There was no significant difference in terms of ROM in the L-ESWT group, while there was slight improvement of forward flexion in the ESWT-FM group after the fifth treatment. Conclusions: ESWT-FM provided faster pain relief and slightly more notable improvement of function compared with L-ESWT for the patients with adhesive capsulitis of shoulder. PMID- 29581970 TI - Polymorphisms in the Osteopontin Are Associated with Susceptibility to Ankylosing Spondylitis in a Han Chinese Population. AB - The aim of this study was to investigate whether osteopontin (OPN) variants are associated with susceptibility to ankylosing spondylitis (AS) in a Chinese population. Polymorphisms at the 9175th position in exon 7 of OPN and rs17524488 were genotyped using direct sequencing in 186 unrelated AS patients and 188 ethnically matched healthy controls. Serum concentration of OPN was measured by enzyme-linked immunosorbent assay (ELISA) in all participants. AS patients displayed significantly higher OPN serum levels than the controls (P < 001). A heterozygous, novel 9175 T>A in exon 7 of the OPN gene was found in this study. In healthy controls, subjects carrying the rs17524488 G/G genotype of the OPN display significantly higher OPN serum levels than the GG/GG genotype (P < 0.05). Plasma OPN level is implicated as an early diagnostic marker of AS. The novel 9175th- (exon 7) position polymorphism of OPN and rs17524488 were related to susceptibility to AS in a Chinese population, the rs17524488 G/G genotype may be involved in the pathogenesis of AS, and the precise molecular mechanism underlying the influence of OPN polymorphisms on the development of AS remains to be determined in the further prospective studies. PMID- 29581971 TI - Chemoradiotherapy as Definitive Treatment for Elderly Patients with Head and Neck Cancer. AB - Background: With the aging population and a rising incidence of squamous cell carcinoma of the head and neck (SCCHN), there is an emerging need for developing strategies to treat elderly patients. Patients and Methods: We retrospectively analyzed 158 patients treated with definitive, concurrent chemoradiotherapy (CRT) for SCCHN. Clinicopathological characteristics, acute toxicities, and oncological outcomes were compared between patients younger and older than (or of age equal to) 65, 70, and 75 years. Results: RT dose, chemotherapy regimen, and total chemotherapy dose were balanced between the groups. After a median follow-up of 29 months, overall survival (OS), progression-free survival (PFS), local control rate, and distant metastasis-free survival stratified by age of >=65, >=70, or >=75 years revealed no differences. The rate of acute toxicities was also not higher for older patients. Worse ECOG performance score (ECOG 2-3) was associated with impaired OS (p = 0.004) and PFS (p = 0.048). Conclusion: Definitive treatment with CRT for SCCHN is feasible and effective; even in advanced age treatment decisions should be made according to general condition and comorbidity, rather than calendar age alone. PMID- 29581972 TI - Effect of Curcumin-Nanoemulsion Associated with Photodynamic Therapy in Cervical Carcinoma Cell Lines. AB - Cervical cancer is the fourth cause of cancer death in women. Curcumin has antineoplastic properties. Furthermore, curcumin may be used as a photosensitizing agent in Photodynamic Therapy. This study aimed to investigate the effects of Photodynamic Therapy in cellular viability using curcumin nanoemulsion as a photosensitizing drug in cervical carcinoma cell lines. The empty nanoemulsion presented very low cytotoxicity in all cell lines analyzed. Additionally, the incubation with curcumin-nanoemulsion at 20 MUM of curcumin showed more than 80% of cell viability for cell lines. Nanoemulsions were shown to be internalized inside cells by fluorescence microscopy and were observed in the intracellular environment for up to 36 hours after incubation with cell lines. In addition, after the Photodynamic Therapy we observed a high phototoxic effect of the curcumin-nanoemulsion with less than 5% of viable cells after irradiation. This was accompanied by an increase in caspase-3/caspase-7 activities after cell treatment with curcumin-nanoemulsion and Photodynamic Therapy, suggesting cell death by apoptosis. We conclude that the curcumin nanoemulsion formulation behaves as a photosensitizing drug in Photodynamic Therapy and shows potential as an alternative treatment to cervical lesions using an endoscopic diode fiber laser setup for in situ activation or cavity activation using a diffuse fiber delivery system. PMID- 29581974 TI - Biomechanical Evaluation of a Novel Apatite-Wollastonite Ceramic Cage Design for Lumbar Interbody Fusion: A Finite Element Model Study. AB - Objectives: Cage design and material properties play a crucial role in the long term results, since interbody fusions using intervertebral cages have become one of the basic procedures in spinal surgery. Our aim is to design a novel Apatite Wollastonite interbody fusion cage and evaluate its biomechanical behavior in silico in a segmental spinal model. Materials and Methods: Mechanical properties for the Apatite-Wollastonite bioceramic cages were obtained by fitting finite element results to the experimental compression behavior of a cage prototype. The prototype was made from hydroxyapatite, pseudowollastonite, and frit by sintering. The elastic modulus of the material was found to be 32 GPa. Three intact lumbar vertebral segments were modelled with the ANSYS 12.0.1 software and this model was modified to simulate a Posterior Lumbar Interbody Fusion. Four cage designs in different geometries were analyzed in silico under axial loading, flexion, extension, and lateral bending. Results: The K2 design had the best overall biomechanical performance for the loads considered. Maximum cage stress recorded was 36.7 MPa in compression after a flexion load, which was within the biomechanical limits of the cage. Conclusion: Biomechanical analyses suggest that K2 bioceramic cage is an optimal design and reveals essential material properties for a stable interbody fusion. PMID- 29581973 TI - Computational Investigation on the Biomechanical Responses of the Osteocytes to the Compressive Stimulus: A Poroelastic Model. AB - Osteocytes, the major type of bone cells embedded in the bone matrix and surrounded by the lacunar and canalicular system, can serve as biomechanosensors and biomechanotranducers of the bone. Theoretical analytical methods have been employed to investigate the biomechanical responses of osteocytes in vivo; the poroelastic properties have not been taken into consideration in the three dimensional (3D) finite element model. In this study, a 3D poroelastic idealized finite element model was developed and was used to predict biomechanical behaviours (maximal principal strain, pore pressure, and fluid velocity) of the osteocyte-lacunar-canalicular system under 150-, 1000-, 3000-, and 5000 microstrain compressive loads, respectively, representing disuse, physiological, overuse, and pathological overload loading stimuli. The highest local strain, pore pressure, and fluid velocity were found to be highest at the proximal region of cell processes. These data suggest that the strain, pore pressure, and fluid velocity of the osteocyte-lacunar-canalicular system increase with the global loading and that the poroelastic material property affects the biomechanical responses to the compressive stimulus. This new model can be used to predict the mechanobiological behaviours of osteocytes under the four different compressive loadings and may provide an insight into the mechanisms of mechanosensation and mechanotransduction of the bone. PMID- 29581975 TI - The Role of Actin Dynamics and Actin-Binding Proteins Expression in Epithelial-to Mesenchymal Transition and Its Association with Cancer Progression and Evaluation of Possible Therapeutic Targets. AB - Metastasis causes death of 90% of cancer patients, so it is the most significant issue associated with cancer disease. Thus, it is no surprise that many researchers are trying to develop drugs targeting or preventing them. The secondary tumour site formation is closely related to phenomena like epithelial to-mesenchymal and its reverse, mesenchymal-to-epithelial transition. The change of the cells' phenotype to mesenchymal involves the acquisition of migratory potential. Cancer cells movement is possible due to the development of invasive structures like invadopodia, lamellipodia, and filopodia. These changes are dependent on the reorganization of the actin cytoskeleton. In turn, the polymerization and depolymerization of actin are controlled by actin-binding proteins. In many tumour cells, the actin and actin-associated proteins are accumulated in the cell nucleus, suggesting that it may also affect the progression of cancer by regulating gene expression. Once the cancer cell reaches a new habitat it again acquires epithelial features and thus proliferative activity. Targeting of epithelial-to-mesenchymal or/and mesenchymal-to-epithelial transitions through regulation of their main components expression may be a potential solution to the problem of metastasis. This work focuses on the role of these processes in tumour progression and the assessment of therapeutic potential of agents targeting them. PMID- 29581977 TI - Association between Sleep Apnea Hypopnea Syndrome and the Risk of Atrial Fibrillation: A Meta-Analysis of Cohort Study. AB - Numerous reports have been done to seek the relationship between sleep apnea hypopnea syndrome (SAHS) and the risk of atrial fibrillation (AF). However, definite conclusion has not yet been fully established. We examined whether SAHS increases AF incidence in common population and summarized all existing studies in a meta-analysis. We summarized the current studies by searching related database for potential papers of the association between SAHS and the risk of AF. Studies that reported original data or relative risks (RRs) with 95% confidence intervals (CIs) for the associations were included. Sensitivity analyses were performed by omitting each study iteratively and publication bias was detected by Begg's tests. Eight eligible studies met the inclusion criteria. Fixed effects meta-analysis showed that SAHS increased AF risk in the common population (RR = 1.70, 95% CI: 1.53-1.89, P = 0.002, I2 = 69.2%). There was a significant association between mild SAHS and the risk of AF (RR = 1.52, 95% CI: 1.28-1.79, P = 0.01, I2 = 78.4%), moderate SAHS (RR = 1.88, 95% CI: 1.55-2.27, P = 0.017, I2 = 75.6%), and severe SAHS (RR = 2.16, 95% CI: 1.78-2.62, P < 0.001, I2 = 91.0%). The results suggest that sleep apnea hypopnea syndrome could increase the risk of AF, and the higher the severity of SAHS, the higher risk of atrial fibrillation. PMID- 29581976 TI - Hypoxia Enhances Fusion of Oral Squamous Carcinoma Cells and Epithelial Cells Partly via the Epithelial-Mesenchymal Transition of Epithelial Cells. AB - Increasing evidence and indications showed that cell fusion is crucial in tumor development and metastasis, and hypoxia, a closely linked factor to tumor microenvironment, which can lead to EMT, induces angiogenesis and metastasis in tumor growth. However, the relationship between hypoxia and fusion has not been reported yet. EMT will change some proteins in the epithelial cell surface and the changes of proteins in cell surface may increase cell fusion. This study found that hypoxia promotes the spontaneous cell fusion between Oral Squamous Carcinoma Cells (OSCCs) and Human Immortalized Oral Epithelial Cells (HIOECs). At the same time, Hypoxia can lead to EMT, and hypoxia-pretreated HIOECs increased fusion rate with OSCC, while the fusion rate was significantly reduced by DAPT, a kind of EMT blocker. Therefore, epithelial cells can increase spontaneously cell fusion with OSCC by EMT. Our study may provide a new insight to link among tumor microenvironment, cell fusion, and cancer. PMID- 29581978 TI - Suprapedicular Circumferential Opening Technique of Percutaneous Endoscopic Transforaminal Lumbar Discectomy for High Grade Inferiorly Migrated Lumbar Disc Herniation. AB - Purpose: To evaluate the efficacy of suprapedicular circumferential opening technique (SCOT) of percutaneous endoscopic transforaminal lumbar discectomy (PETLD) for high grade inferiorly migrated lumbar disc herniation. Material and Methods: Eighteen consecutive patients who presented with back and leg pain with a single-level high grade inferiorly migrated lumbar disc herniation were included. High grade inferiorly migrated disc was removed by the SCOT through PETLD approach. Outcome evaluation was done with visual analog scale (VAS) and Mac Nab's criteria. Result: There were 14 males and 4 females. The mean age of patients was 53.3 +/- 14.12 years. One, 4, and 13 patients had disc herniation at L1-2, L3-4, and L4-5 levels, respectively, on MRI, which correlated with clinical findings. The mean follow-up duration was 8.4 +/- 4.31 months. According to Mac Nab's criteria, 9 patients (50%) reported excellent and the remaining 9 patients (50%) reported good outcomes. The mean preoperative and postoperative VAS for leg pain were 7.36 +/- 0.73 and 1.45 +/- 0.60, respectively (p < 0.001). Improvement in outcomes was maintained even at final follow-up. There was no complication. Conclusion: In this preliminary study we achieved good to excellent clinical results using the SCOT of PETLD for high grade inferiorly migrated lumbar disc herniation. PMID- 29581979 TI - Current Strategies of Endocrine Therapy in Elderly Patients with Breast Cancer. AB - Currently, the growing population of the elderly is one of biggest problems in terms of increase in geriatric diseases. Lack of data from large prospective studies on geriatric breast cancer patients often makes it difficult for clinicians to make treatments decisions for them. Because both benefit and risk of treatment should be taken into account, treatment is usually determined considering life expectancy or comorbidities in elderly patients. Treatment of breast cancer is differentiated according to histologic classifications, and hormone therapy is even adopted for patients with metastatic breast cancer if tumor tissue expresses hormone receptors. Endocrine therapy can offer great benefit to elderly patients considering its equivalent efficacy to chemotherapy with fewer toxicities if it is appropriately used. Aromatase inhibitors are usually prescribed agents in hormone therapy for elderly breast cancer patients due to their physiology after menopause. Here, endocrine therapy for elderly patients with breast cancer in neoadjuvant, adjuvant, and palliative setting is reviewed along with predictive adverse events resulting from the use of hormone agents. PMID- 29581980 TI - Mineral and Phytochemical Profiles and Antioxidant Activity of Herbal Material from Two Temperate Astragalus Species. AB - Only a few species of the large Astragalus genus, widely used for medicinal purposes, have been thoroughly studied for phytochemical composition. The aim of our research was to investigate the rarely studied species A. glycyphyllos L. and A. cicer L. for the distribution of mineral elements and phytochemicals in whole plants at two growth stages and in morphological fractions. We also investigated the capacity of the plant extracts to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and to chelate ferrous ions. Chemical composition and antioxidant properties depended on species, maturity, and plant part. Herbal material of A. glycyphyllos was richer in Fe, total phenolics, and flavonoids, whereas extracts of A. cicer showed a higher antioxidant activity. Young plants had more isoflavones, showed greater quenching of DPPH radicals, and exhibited better mineral profiles than flowering plants. Among plant parts, leaves were the most valuable plant material according to most characteristics investigated. Isoflavone concentration in flowers was lower than in leaves and stems. None of the Astragalus samples contained detectable amounts of the alkaloid swainsonine. The study demonstrates the potential of plant material from two Astragalus species as a valuable source of iron, phenolic substances including isoflavones, free-radical scavengers, and Fe2+ chelators for pharmaceutical use. PMID- 29581981 TI - Mechanism of Activating the Proprioceptive NT-3/TrkC Signalling Pathway by Reverse Intervention for the Anterior Cruciate Ligament-Hamstring Reflex Arc with Electroacupuncture. AB - The anterior cruciate ligament (ACL) is an important structure maintaining stability of the knee joints. Deficits in physical stability and the proprioceptive capabilities of the knee joints are observed, when the ACL is damaged. Additionally, a unilateral ACL injury can affect bilateral knee proprioception; therefore, proprioception of the ACL may play a key role in stability. Electroacupuncture therapy has a definite effect nerve regeneration. In this study, cynomolgus monkeys were randomly divided into 4 groups: the model control group, intervention of the injured knee with electroacupuncture (IIKE) group, intervention of the bilateral knees with electroacupuncture (IBKE) group, and the blank control group. The unilateral ACL injury model was developed in IIKE and IBKE groups; acupuncture points around the knees underwent intervention similarly in the IIKE and IBKE groups. Then, mRNA and protein expressions of NT-3 and TrkC in the dorsal root ganglion and of growth-associated protein-43 in the ACL increased according to reverse-transcription quantitative polymerase chain reaction and Western blotting results. Decreased incubations and increased amplitudes were found for somatosensory-evoked potentials and motor nerve conduction velocity. The finding indicates that electroacupuncture may play an important role in the recovery of proprioception in the ACL by activating the NT 3/TrkC signalling pathway. PMID- 29581982 TI - TGF-alpha Overexpression in Breast Cancer Bone Metastasis and Primary Lesions and TGF-alpha Enhancement of Expression of Procancer Metastasis Cytokines in Bone Marrow Mesenchymal Stem Cells. AB - Bone metastasis (BM) is the advanced complication of breast cancer, while bone marrow-derived mesenchymal stem cells (BMSCs) in the microenvironment unclearly contribute to cancer metastasis. This study investigated potential roles of transforming growth factor- (TGF-) alpha in the interaction between breast cancer and BMSCs in BM. Clinical cases of breast cancer with bone metastasis (BMBC), breast cancer without bone metastasis (Non-BM-BC), and benign fibroadenoma (Benign) were enlisted in a retrospective study. TGF-alpha was found obviously overexpressed in BM lesion of BMBC compared to primary lesion of both BMBC and Non-BM-BC (P < 0.01), and TGF-alpha was higher in primary lesion of both BMBC and Non-BM-BC (P < 0.01) than Benign group. Interestingly, TGF-alpha in nontumor tissues of both BMBC and Non-BM-BC was at a higher level than Benign group (P < 0.01), and numbers of macrophages in nontumor tissues of both BMBC and Non-BM-BC (P < 0.01) were higher than Benign group. Furthermore, in cultured human BMSCs, TGF-alpha stimulated production of procancer cytokines including IL-6, VEGF, FGF10, FGF17, and TGF-beta1 in a dose-dependent manner. Thus, TGF-alpha in BC could potentially be an important signal of carcinogenesis and metastasis. Macrophages in the nontumor tissue of BC may not be protective but could promote cancer metastasis. PMID- 29581983 TI - Clinical Characteristics and Survival Outcomes for Non-Small-Cell Lung Cancer Patients with Epidermal Growth Factor Receptor Double Mutations. AB - Multiple randomized clinical trials have demonstrated that epidermal growth factor receptor (EGFR) exon 19 deletion (19Del) and exon 21 L858R mutation (L858R) are highly correlated with sensitivity to epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment in non-small-cell lung cancer (NSCLC). A mutation in exon 20 (T790M) is reportedly associated with resistance to EGFR-TKIs. However, few studies have focused on patients harboring double mutations in these 3 mutation sites. In this retrospective study, forty five patients (45/2546, 1.7%) harbored double mutations of 19Del, L858R, and T790M. Twenty-four patients with EGFR double mutations received EGFR-TKI therapy. Clinical characteristics of these patients, including the response to EGFR-TKIs and progression-free survival outcome for EGFR-TKI treatment (PFS-TKI), were analyzed. Patients with EGFR double mutations were more likely to be nonsmokers, have an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-1, have adenocarcinoma, and be at stage III-IV. The ORR, DCR, and median PFS-TKI in patients harboring EGFR double mutations were lower than in patients with a single EGFR-activating mutation. The differences in ORR and DCR were statistically insignificant between the 3 groups. Patients with double mutations of 19Del and T790M had longer PFS-TKIs than patients in the other 2 groups. PMID- 29581984 TI - Dynamic Changes in Plasma MicroRNAs Have Potential Predictive Values in Monitoring Recurrence and Metastasis of Nasopharyngeal Carcinoma. AB - Although circulating microRNAs (miRNAs) have already proven to be useful as diagnostic and prognostic biomarkers in nasopharyngeal carcinoma (NPC), the potential of these molecules to monitor patients over time has been less explored. This study aimed to analyze dynamic changes in plasma miRNAs before and after treatment and explore their clinical significance in monitoring recurrence and metastasis of NPC. Candidate miRNAs were screened by microarray analysis and validated by real-time quantitative polymerase chain reaction (RT-qPCR). In the follow-up cohort including 102 patients, blood samples (plasma) were collected before the treatment initiation, 3 months, 6 months, and 12 months after treatments, and at the time of any recurrence or metastasis. Among these plasma miRNAs, miR-9-3p, miR-124-3p, miR-892b, and miR-3676-3p were significantly upregulated (P = 0.018, P = 0.039, P = 0.001, and P = 0.01, resp.) after treatment compared with pretreatment, and the four plasma miRNAs were downregulated again at recurrence or metastasis (P < 0.001, P = 0.015, P = 0.003, and P = 0.026, resp.). The dynamic changes in plasma miRNAs after treatment reflect the outcome of the disease and have the potential to monitor recurrence and metastasis in patients with NPC. PMID- 29581985 TI - The Feasibility of 3D Printing Technology on the Treatment of Pilon Fracture and Its Effect on Doctor-Patient Communication. AB - Purpose: The aim of this study was to assess the feasibility and effectiveness of the three-dimensional (3D) printing technology in the treatment of Pilon fractures. Methods: 100 patients with Pilon fractures from March 2013 to December 2016 were enrolled in our study. They were divided randomly into 3D printing group (n = 50) and conventional group (n = 50). The 3D models were used to simulate the surgery and carry out the surgery according to plan in 3D printing group. Operation time, blood loss, fluoroscopy times, fracture union time, and fracture reduction as well as functional outcomes including VAS and AOFAS score and complications were recorded. To examine the feasibility of this approach, we invited surgeons and patients to complete questionnaires. Results: 3D printing group showed significantly shorter operation time, less blood loss volume and fluoroscopy times, higher rate of anatomic reduction and rate of excellent and good outcome than conventional group (P < 0.001, P < 0.001, P < 0.001, P = 0.040, and P = 0.029, resp.). However, no significant difference was observed in complications between the two groups (P = 0.510). Furthermore, the questionnaire suggested that both surgeons and patients got high scores of overall satisfaction with the use of 3D printing models. Conclusion: Our study indicated that the use of 3D printing technology to treat Pilon fractures in clinical practice is feasible. PMID- 29581986 TI - Negative Mood States Correlate with Laterobasal Amygdala in Collegiate Football Players. AB - A number of studies have suggested that sports-related concussion (SRC) may place individuals at increased risk for depression and negative outcomes including suicide. However, the mechanisms underlying a potential relationship between brain integrity and mood remain unclear. The current study is aimed at examining the association between amygdala shape, mood state, and postconcussion symptoms in collegiate football players. Thirty members of 1 football team completed the Profile of Mood States (POMS), the postconcussion symptom scale (PCSS), and an MRI protocol during preseason camp. T1-weighted images were acquired and three dimensional amygdala and probabilistic maps were created for shape analysis. Correlation analyses between POMS and PCSS and the relationship between POMS and amygdala shape were completed. In the amygdala, the left laterobasal subregion showed a positive relationship with the POMS total score and subscales scores. No significant relationship between PCSS and amygdala shape was found. Significant positive correlations were found between POMS subscales and PCSS. These results indicate that amygdala structure may be more closely associated with negative mood states than postconcussion symptoms. These findings suggest that premorbid individual differences in effect may provide critical insight into the relationship between negative mood and outcomes in collegiate football players with SRC.

AB - To ensure the biomechanical properties of Ti-24Nb-4Zr-8Sn, stress-shielding effects were compared between Ti-24Nb-4Zr-8Sn and Ti-6Al-4V fixation by using a porcine model. Twelve thoracolumbar spines (T12-L5) of 12-month-old male pigs were randomly divided into two groups: Ti-24Nb-4Zr-8Sn (EG, n = 6) and Ti-6Al-4V (RG, n = 6) fixation. Pedicle screw was fixed at the outer edge of L4-5 vertebral holes. Fourteen measuring points were selected on the front of transverse process and middle and posterior of L4-5 vertebra. Electronic universal testing machine was used to measure the strain resistance of measuring points after forward and backward flexion loading of 150 N. Meanwhile, stress resistance was compared between both groups. The strain and stress resistance of measurement points 1, 2, 5, 6, 9, and 10-14 in Ti-24Nb-4Zr-8Sn fixation was lower than that of Ti-6Al-4V fixation after forward and backward flexion loading (P < 0.05). The strain and stress resistance of measurement points 3, 4, 7, and 8 was higher in Ti-24Nb-4Zr 8Sn fixation than that of Ti-6Al-4V fixation (P < 0.05). Stress-shielding effects of Ti-24Nb-4Zr-8Sn internal fixation were less than that of Ti-6Al-4V internal fixation. These results suggest that Ti-24Nb-4Zr-8Sn elastic fixation has more biomechanical goals than conventional Ti-6Al-4V internal fixation by reducing stress-shielding effects.

AB - Visceral leishmaniasis (VL) is considered as a major health threat in the Indian subcontinent. Leishmania donovani, a usually visceralizing species, causes cutaneous leishmaniasis (CL) in Sri Lanka. However, visceralizing potential of the local L. donovani is not yet fully understood. This project studied the seroprevalence of local CL by using an in-house ELISA. An IgG-based ELISA using crude Leishmania antigen (Ag) was developed and validated. A total of 50 laboratory confirmed cases of locally acquired CL were examined using the newly developed ELISA. According to the optimized ELISA, seroprevalence of anti Leishmania IgG antibodies in the study group was 34.0% (n = 17/50). Majority of seropositive individuals were males (n = 13/17), representing 76%. Nearly half of the seropositive individuals were young adults (20-40 years, n = 9/17, 53%). Higher proportions of single lesions, large lesions, and nodular lesions were associated with a seroconversion. A proportion of local L. donovani infections leading to CL have the ability to raise an antibody response in the host. This may indicate early systemic involvement as one possibility. Study of a large number of patients with adequate follow-up would be useful. PMID- 29581990 TI - Inter- and Intraspecific Variations in the Pectoral Muscles of Common Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and Humans (Homo sapiens). AB - We have analyzed anatomic variations in the pectoralis major and pectoralis minor muscles of common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) and compared them to anatomic variations in these muscles in humans (Homo sapiens). We have macroscopically dissected these muscles in six adult Pan troglodytes, five Pan paniscus of ages ranging from fetus to adult, and five adult Homo sapiens. Although Pan troglodytes are thought to lack a separate pectoralis abdominis muscle, we have identified this muscle in three of the Pan troglodytes; none of the Pan paniscus, however, had this muscle. We have also found deep supernumerary fascicles in the pectoralis major of two Pan troglodytes and all five Pan paniscus. In all six Pan troglodytes, the pectoralis minor was inserted at the supraspinatus tendon, while, in Pan paniscus and Homo sapiens, it was inserted at the coracoid process of the scapula. Some of the anatomic features and variations of these muscles in common chimpanzees and bonobos are similar to those found in humans, therefore enhancing our knowledge of primate comparative anatomy and evolution and also shedding light on several clinical issues. PMID- 29581987 TI - Biochemical Stimulus-Based Strategies for Meniscus Tissue Engineering and Regeneration. AB - Meniscus injuries are very common and still pose a challenge for the orthopedic surgeon. Meniscus injuries in the inner two-thirds of the meniscus remain incurable. Tissue-engineered meniscus strategies seem to offer a new approach for treating meniscus injuries with a combination of seed cells, scaffolds, and biochemical or biomechanical stimulation. Cell- or scaffold-based strategies play a pivotal role in meniscus regeneration. Similarly, biochemical and biomechanical stimulation are also important. Seed cells and scaffolds can be used to construct a tissue-engineered tissue; however, stimulation to enhance tissue maturation and remodeling is still needed. Such stimulation can be biomechanical or biochemical, but this review focuses only on biochemical stimulation. Growth factors (GFs) are one of the most important forms of biochemical stimulation. Frequently used GFs always play a critical role in normal limb development and growth. Further understanding of the functional mechanism of GFs will help scientists to design the best therapy strategies. In this review, we summarize some of the most important GFs in tissue-engineered menisci, as well as other types of biological stimulation. PMID- 29581991 TI - Lifetime Traumatic Experiences and Disordered Eating among University Students: The Role of Posttraumatic Stress Symptoms. AB - The associations between lifetime traumatic events (TEs), posttraumatic stress (PTS) symptoms, and disordered eating (DE) were studied in a sample of 614 university students (mean age 20 years). An anonymous questionnaire included 32 lifetime TEs, IES-revised measured PTS symptoms, and EAT-26 evaluated DE symptoms. Statistical analyses included Pearson correlations and structural equation models (SEM) with bootstrapping method. Findings reveal the prevalence of DE in 8.1% of participants, while 73.9% of students experienced at least one lifetime TE. 52.0% of students with DE had PTS symptoms (p < 0.0001) and 30.8% of students with lifetime TEs had PTS symptoms (p < 0.001). In SEM, direct paths from lifetime TEs to PTS symptoms (0.38, p < 0.0001) and from PTS symptoms to DE (0.40, p < 0.0001) were observed. The final SEM confirmed the mediating role of PTS symptoms in the path between some TEs (traffic accident and seriously injured) and DE among the university students. If PTS symptoms are associated with DE, then addressing PTS symptoms in the context of DE treatment may improve treatment efficacy. PMID- 29581992 TI - Contrast-Enhanced Ultrasound Improves the Pathological Outcomes of US-Guided Core Needle Biopsy That Targets the Viable Area of Anterior Mediastinal Masses. AB - Based on the option that ultrasound-guided core needle biopsy (US-CNB) of the enhanced portion of anterior mediastinal masses (AMMs) identified by contrast enhanced ultrasound (CEUS) would harvest viable tissue and benefit the histological diagnoses, a retrospective study was performed to elucidate the correlation between the prebiopsy CEUS and diagnostic yield of AMMs and found that CEUS potentially improved the diagnostic yield of AMMs compared with conventional US with a significant increase in the cellularity of samples. Furthermore, the marginal blood flow signals and absence of necrosis can predict the diagnostic yield of AMM. It was concluded that US-CNB of the viable part of AMMs, as verified by CEUS, was able to harvest sufficient tissue with more cellularity that could be used for ancillary studies and improve the diagnostic yield. And CEUS was recommended to those patients with AMMs undergoing repeated US-CNB, with the absence of marginal blood signals or presence of necrosis. PMID- 29581993 TI - Hypereosinophilic Syndrome Complicated by Eosinophilic Myocarditis With Dramatic Response to Steroid. AB - Introduction. Eosinophilic myocarditis is an infiltrative disease that affects the myocardium leading to various presentations. It can be precipitated by medications, helminthiasis, or hypereosinophilic syndrome. Case. We present the case of a young, male patient who presented with palpitations and dyspnea and was found to have heart failure with reduced ejection fracture of 12%. His past medical history was significant for recent lung problem treated with steroids. Based on his history and laboratory findings, he was started on intravenous steroids for treatment of eosinophilic myocarditis. Within 3 days, his ejection fracture improved to 35%. Conclusion. Given the nonspecific clinical presentations, mimicking other diseases, high index of suspicion is warranted to diagnose eosinophilic myocarditis. This is crucial as early detection and treatment with steroids can lead to a dramatic response. PMID- 29581994 TI - Does the Reliability of Reporting in Injury Surveillance Studies Depend on Injury Definition? AB - Background: Choosing an appropriate definition for injury in injury surveillance studies is essential to ensure a balance among reporting reliability, providing an accurate representation of injury risk, and describing the nature of the clinical demand. Purpose: To provide guidance on the choice of injury definition for injury surveillance studies by comparing within- and between-team variability in injury incidence with >24-hour and >7-day time-loss injury definitions in a large multiteam injury surveillance study. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Injury data were reported for 2248 professional rugby union players from 15 Premiership Rugby clubs over 12 seasons. Within-team percentage coefficient of variation and mean between-team standard deviation (expressed as a percentage coefficient of variation) in injury incidence rates (injuries per 1000 player match hours) were calculated. For both variables, a comparison was made between >24-hour and >7-day injury incidence rates in terms of the magnitude of the observed effects. Results: The overall mean incidence across the population with a >24-hour time-loss injury definition was approximately double the reported incidence with the >7-day definition. There was a 10% higher between-team variation in match injury incidence rates with the >24-hour time-loss definition versus the >7-day definition. Conclusion: There was a likely higher degree of between-team variation in match injury incidence rates with a >24-hour time-loss definition than with a >7-day definition of injury. However, in professional sports settings, it is likely that the benefits of using a more inclusive definition of injury (improved understanding of clinical demand and the appropriate and accurate reporting of injury risk) outweigh the small increase in variation in reporting consistency. PMID- 29581995 TI - Role of Rotational Kinematics in Minimizing Elbow Varus Torques for Professional Versus High School Pitchers. AB - Background: Elbow injury rates among baseball pitchers are rapidly rising. However, this increase has been most dramatic among high school (HS) pitchers. Purpose: To examine pitch velocity and the kinetic and kinematic characteristics of HS versus professional (PRO) pitchers to identify potential differences that may play a role in the increased risk of ulnar collateral ligament injury in youth pitchers. Study Design: Controlled laboratory study. Methods: A total of 37 HS (mean +/- SD: age, 16 +/- 1 years) and 40 PRO (age, 21 +/- 2 years) baseball pitchers completed maximal-effort baseball pitches during a single testing session, from which pitch velocity (PV), absolute and normalized elbow varus torque (EVTA and EVTN, respectively) during arm cocking and at maximum shoulder external rotation (MER), and 8 other elbow and shoulder torques or forces and rotational kinematics of the pelvis and trunk were analyzed, recorded, and compared. Results: PV was greater in PRO than HS athletes; EVTA was greater in PRO than HS athletes during arm cocking and at MER; but EVTN was similar during arm cocking and greater in HS than PRO athletes at MER. In PRO athletes, PV was not related to EVTA during arm cocking or MER (r = 0.01-0.05). Furthermore, in PRO athletes, EVTA during arm cocking and at MER were inversely related to upper trunk rotation at hand separation and foot contact and to pelvis rotation at elbow extension (r = -0.30 to -0.33). In contrast, in HS athletes, PV was strongly related to EVTA during arm cocking and MER (r = 0.76-0.77). Furthermore, in HS athletes, PV and EVTA during arm cocking and at MER were moderately or strongly related to the other elbow and shoulder torques and forces (r = 0.424 0.991), and EVTA was not related to upper trunk rotation or pelvis rotation throughout the throwing motion (r = -0.16 to 0.15). Conclusion: The kinetic and rotational kinematic differences observed between PRO and HS pitchers in this study may help explain the greater performance of PRO pitchers while allowing them to minimize EVT during pitching. HS pitchers, however, do not appear to be as capable of utilizing the forces generated by rotation of their trunk and pelvis to aid in pitching, and those who throw the hardest generate the greatest forces at the shoulder and elbow. As a result, they experience higher EVTs relative to their body size, which may place them at an increased risk of injury. Clinical Relevance: HS pitchers throw harder primarily by generating larger forces in the arm and shoulder. Thus, owing to the relative physical immaturity of HS versus PRO pitchers, these factors may place them at an increased risk of injury. Coaches may first wish to focus on improving the rotational kinematics of HS pitchers rather than first focusing on achieving greater pitch velocities. PMID- 29581996 TI - A 5-Strand Hamstring Autograft Achieves Outcomes Comparable to Those of a 4 Strand Hamstring Autograft With a Graft Diameter of 8 mm or More in Anterior Cruciate Ligament Reconstruction. AB - Background: Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose: To report the outcomes of primary ACL reconstruction using 5 strand hamstring autografts in patients in whom the 4-strand configuration produced a graft diameter of <8 mm and to compare these outcomes with those of ACL reconstruction using 4-strand semitendinosus-gracilis autografts with a graft diameter of >=8 mm. Study Design: Cohort study; Level of evidence, 2. Methods: The primary study group comprised 25 patients who underwent ACL reconstruction using a 5-strand hamstring autograft. The comparison group comprised 20 patients who underwent ACL reconstruction using a 4-strand hamstring autograft with a graft diameter of >=8 mm. Interference screw fixation was used at the tibial and femoral ends for both groups of patients. Subjective questionnaires, including the Knee injury and Osteoarthritis Outcome Score (KOOS), the Lysholm score, and the Physical Component Summary and Mental Component Summary of the Short Form-36 (SF-36), were administered preoperatively as well as at 1- and 2-year follow-up visits. Results: There were no significant differences in the patient demographics and preoperative scores between the 2 groups. The mean graft diameter was 9.06 +/- 0.60 mm in the 5-strand group and 8.13 +/- 0.32 mm in the 4 strand group (P < .05). There was no statistically significant difference between groups on postoperative Lysholm, KOOS Pain, KOOS Symptoms, KOOS Activities of Daily Living, KOOS Sports, KOOS Quality of Life, and SF-36 Physical Component Summary scores. Conclusion: In primary ACL reconstruction, the 5-strand hamstring autograft achieves clinical outcomes that are comparable to those of the 4-strand hamstring autograft with a graft diameter of >=8 mm. The 5-strand graft technique is therefore a useful means of increasing the graft diameter when faced with an undersized hamstring graft. PMID- 29581997 TI - Cardiac Arrest in a Vitamin D-Deficient Infant. PMID- 29581999 TI - Astrocyte dysfunction following molybdenum-associated purine loading could initiate Parkinson's disease with dementia. AB - Sporadic or idiopathic Parkinson's disease is a movement disorder with a worldwide distribution, a long pre-clinical latent period and a frequent association with dementia. The combination of molybdenum deficiency and purine ingestion could explain the movement disorder, the distribution, the latent period and the dementia association. Recent studies in sheep have shown that molybdenum deficiency enables some dietary purines to accumulate in the central nervous system. This causes astrocyte dysfunction, altered neuromodulation and eventually irreversible central nervous system disease. Humans and sheep share the ability to salvage purines and this ability places humans at risk when they ingest xanthosine, inosine, adenosine and guanosine. Adenosine ingestion in molybdenum-deficient humans will lead to adenosine loading and potentially a disturbance to the A2a adenosine receptors in the nigro-striatum. This could result in Parkinson's disease. Guanosine ingestion in molybdenum-deficient humans will lead to guanosine loading and potentially a disturbance to the guanosine receptors in the hippocampus, amygdala and ventral striatum. This could result in dementia. The molybdenum content of the average daily diet in the United States is 0.07 ppm and in the United Kingdom 0.04 ppm. Central nervous system disease occurs in sheep at <0.04 ppm. Consistent with the role proposed for molybdenum deficiency in Parkinson's disease is the observation that affected individuals have elevated sulfur amino acid levels, depressed sulfate levels, and depressed uric acid levels. Likewise the geographical distribution of Parkinson's dementia complex on Guam corresponds with the distribution of molybdenum-deficient soils hence molybdenum-deficient food gardens on that island. PMID- 29581998 TI - Long-term effect of critical illness after severe paediatric burn injury on cardiac function in adolescent survivors: an observational study. AB - Background: Sepsis, trauma, and burn injury acutely depress systolic and diastolic cardiac function; data on long-term cardiac sequelae of pediatric critical illness are sparse. This study evaluated long-term systolic and diastolic function, myocardial fibrosis, and exercise tolerance in survivors of severe pediatric burn injury. Methods: Subjects at least 5 years after severe burn (post-burn:PB) and age-matched healthy controls (HC) underwent echocardiography to quantify systolic function (ejection fraction[EF%]), diastolic function (E/e'), and myocardial fibrosis (calibrated integrated backscatter) of the left ventricle. Exercise tolerance was quantified by oxygen consumption (VO2) and heart rate at rest and peak exercise. Demographic information, clinical data, and biomarker expression were used to predict long term cardiac dysfunction and fibrosis. Findings: Sixty-five subjects (PB:40;HC:25) were evaluated. At study date, PB subjects were 19+/-5 years, were at 12+/-4 years postburn, and had burns over 59+/-19% of total body surface area, sustained at 8+/-5 years of age. The PB group had lower EF% (PB:52+/-9%;HC:61+/ 6%; p=0.004), E/e' (PB:9.8+/-2.9;HC: 5.4+/-0.9;p<0.0001), VO2peak (PB:37.9+/ 12;HC: 46+/-8.32 ml/min/kg; p=0.029), and peak heart rate (PB:161+/-26;HC:182+/ 13bpm;p=0.007). The PB group had moderate (28%) or severe (15%) systolic dysfunction, moderate (50%) or severe diastolic dysfunction (21%), and myocardial fibrosis (18%). Biomarkers and clinical parameters predicted myocardial fibrosis, systolic dysfunction, and diastolic dysfunction. Interpretation: Severe pediatric burn injury may have lasting impact on cardiac function into young adulthood and is associated with myocardial fibrosis and reduced exercise tolerance. Given the strong predictive value of systolic and diastolic dysfunction, these patients might be at increased risk for early heart failure, associated morbidity, and mortality.

AB - This concept paper addresses communication issues arising between physicians and their patients. To facilitate the communication of essential diagnostic pathology information to patients, and address their questions and concerns, we propose that "Pathology Explanation Clinics" be created. The Pathology Explanation Clinics would provide a channel for direct communications between pathologists and patients. Pathologists would receive special training as "Certified Pathologist Navigators" in preparation for this role. The goal of Pathology Explanation Clinics would be to help fill gaps in communication of information contained in laboratory reports to patients, further explain its relevance, and improve patient understanding of the meaning of such information and its impact on their health and health-care choices. Effort would be made to ensure that Certified Pathologist Navigators work within the overall coordination of care by the health-care team. PMID- 29582002 TI - The Continuing Fellowship Conundrum. PMID- 29582003 TI - Editor's letter. PMID- 29582000 TI - Rhythmic abilities and musical training in Parkinson's disease: do they help? AB - Rhythmic auditory cues can immediately improve gait in Parkinson's disease. However, this effect varies considerably across patients. The factors associated with this individual variability are not known to date. Patients' rhythmic abilities and musicality (e.g., perceptual and singing abilities, emotional response to music, and musical training) may foster a positive response to rhythmic cues. To examine this hypothesis, we measured gait at baseline and with rhythmic cues in 39 non-demented patients with Parkinson's disease and 39 matched healthy controls. Cognition, rhythmic abilities and general musicality were assessed. A response to cueing was qualified as positive when the stimulation led to a clinically meaningful increase in gait speed. We observed that patients with positive response to cueing (n = 17) were more musically trained, aligned more often their steps to the rhythmic cues while walking, and showed better music perception as well as poorer cognitive flexibility than patients with non positive response (n = 22). Gait performance with rhythmic cues worsened in six patients. We concluded that rhythmic and musical skills, which can be modulated by musical training, may increase beneficial effects of rhythmic auditory cueing in Parkinson's disease. Screening patients in terms of musical/rhythmic abilities and musical training may allow teasing apart patients who are likely to benefit from cueing from those who may worsen their performance due to the stimulation. PMID- 29582004 TI - Now and at the Hour of Death. AB - With Alzheimer disease, the challenge of death can be unique to each who experience it: the caretaker, the family, the health-care professional, and the victim himself. Death of personality, of memory, and of physical skills wears away the fabric of relationships, leaving little hope of any return to normalcy. To some, this reflection exhibits how faith sustains hope and comforts those afflicted, despite the odds of inevitable loss. To others it reflects upon the poignant complexities associated with palliative care and the demand for individualized attention to the beliefs, norms, and values of each situation, no matter the culture, religion, age, or race. No two cases are ever the same in the face of death, yet for those who experience it, all must appreciate how difficult, unique, personal, and memorable such moments can be. PMID- 29582005 TI - Living With Multiple Myeloma: A Focus Group Study of Unmet Needs and Preferences for Survivorship Care. AB - Purpose: To describe the unmet informational, psychological, emotional, social, practical, and physical needs and preferences for posttreatment survivorship care of individuals living with multiple myeloma to inform the development of relevant, person-centered, survivorship services. Methods: An exploratory, descriptive study using 2 focus groups with 14 participants, 6 to 49 months postdiagnosis. Results: Thematic analysis revealed 7 key themes: information needs, experience with health-care professionals, coping with side effects, communicating with family and friends, dealing with emotions, support needs, and living with the chronicity of myeloma. Participants described key characteristics of survivorship care relevant to their needs and indicated they would like a more whole of person approach to follow-up when the main treatment phases had completed. Conclusion: Participants in this study described unmet needs across a breadth of domains that varied over time. The development of flexible, person centered approaches to comprehensive survivorship care is needed to address the considerable quality-of-life issues experienced by people living with multiple myeloma. Nurse-led care may offer 1 viable model to deliver enhanced patient experience-providing the vital "link" that people described as missing from their survivorship care. PMID- 29582006 TI - What's Mine is Yours: Long-Term Experiences of Good Samaritan Organ Donors. AB - This study is a long-term follow-up on the health and quality of life of Good Samaritan living organ donors who donated an average of 10 years ago. Thirteen donors (kidney, liver, and lung) completed 2 surveys. Data from the RAND 36-Item Health Survey showed that for all domains, as well as the physical and mental component summary scales, the Good Samaritan donor outcomes were superior to the general population (P < .0001). Data from the European Living Donor Satisfaction Survey (EULID) showed that in all 8 theme areas, the donors reported statistically significant positive reactions as compared to negative reactions. With regard to self-reported health status, there was a strong, positive correlation between the RAND 36-Item Health Survey and the EULID (n = 13, Pearson correlation coefficient: 0.874). All but 1 donor reported good, very good, or excellent health status. Although donors overwhelmingly reported positivity about the donation experience, narrative comments about adverse events and recipient death must keep transplant teams alert to these critical areas. Good Samaritan organ donors come to the hospital healthy, give a gift to a stranger, and sometimes leave and linger disabled. Donor teams should be observing, questioning, and responding in an effort to maximize their welfare. This research is unique because investigation of the long-term health and psychosocial outcomes of Good Samaritan organ donors is rare. Existing studies that report long-term outcomes of kidney donors do not separately analyze Good Samaritan donor data from related living donors. PMID- 29582007 TI - Carer Appraisal Scale: A Pilot Study of a Novel Carer-Based Assessment of Patient Functioning. AB - Measurement of patient outcomes is an integral part of mental health service evaluation, as well as guiding clinical practice to ensure best outcomes for patients. Moreover, carers have long held a need for a voice in care outcomes. Despite there existing numerous tools for quantifying patient functioning based on clinician assessments or self-reports, there is a serious paucity of tools available for the carers of patients to appraise their functioning. This tool, developed for use in a community aged care psychiatric service, involves 4 sections-a global impression of patient progress, a scorable checklist of patient functioning in multiple domains, a qualitative section for identifying the most pressing concerns from the carer's perspective, and an open-ended feedback on treatment to date. In this pilot study, the Carer Appraisal Scale was found to have a fair correlation with the Health of Nation Outcomes Scale for over 65. This tool has potential for use in community aged care psychiatric services, as it provides a framework for communication of concerns, assists in prioritizing care, and adds value to clinician treatment plans, as well as providing another dimension to assessment of the patient while empowering carers in care participation. Practical implications of its use, limitations, and potential for modifications are also discussed. PMID- 29582008 TI - Patient-Centered Obstetric Care in the Age of Cell-Free Fetal DNA Prenatal Screening. AB - Purpose: The clinical introduction of innovative prenatal genetic technologies challenges patients and providers to find new ways of fostering informed decision making in a setting characterized by complexity and uncertainty. As prenatal genetic technology advances, important questions remain about how to structure patient-centered conversations that effectively prepare pregnant patients to make informed choices about the different genetic conditions for which this new form screening may be used. Methods: Focus groups were conducted with 23 pregnant women to identify informational needs and decision-making preferences regarding emerging and anticipated applications of cell-free fetal DNA screening, the newest form of prenatal genetic screening. Results: Participants were in favor of obtaining more genetic information about the fetus than provided by conventional screens but acknowledged the challenges inherent in navigating the unique complexities of the decision-making process. The provider-patient relationship was seen as an important resource to navigate the associated uncertainties at each stage of the screening process. Participants emphasized the need for initiatives to support a personalized, accurate, and unbiased discussion about prenatal genetic risk and assessment. Conclusion: Continued advances in prenatal genetic screening call for new approaches to structure patient-centered communication to facilitate increasingly complex decisions about fetal genetic risk and assessment. PMID- 29582009 TI - Developing and Translating a New Model for Teaching Empowerment Into Routine Chronic Care Management: An International Patient-Centered Project. AB - Background: Health professional education has been criticized for not integrating patient expertise into professional curricula to develop professional skills in patient empowerment. Objective: To develop and translate a new expert patient centered model for teaching empowerment into professional education about routine chronic care management. Methods: Eight Finnish patients (known as expert patients), 31 students, and 11 lecturers from 4 European countries participated in a new pilot intensive educational module. Thirteen focus groups, artefacts, and an online student evaluation were analyzed using a thematic analysis and triangulated using a meta-matrix. Results: A patient-centered pedagogical model is presented, which describes 3 phases of empowerment: (1) preliminary work, (2) the elements of empowerment, and (3) the expected outcomes. These 3 phases were bound by 2 cross-cutting themes "time" and "enabling resources." Conclusion: Patient expertise was embedded into the new module curriculum. Using an example of care planning, and Pentland and Feldman's theory of routine organization, the results are translated into a patient-centered educational model for teaching empowerment to health profession students. PMID- 29582010 TI - Dimensions of Phenomenology in Exploring Patient's Suffering in Long-Life Illnesses: Qualitative Evidence Synthesis. AB - Background: Patients' suffering has been increasingly investigated by health-care researchers especially in the chronically ill. Suffering is viewed as a progressive negative consequence that associated with pain, impaired self-esteem, and social alienation. This qualitative evidence synthesis aimed to provide further insights into the application of phenomenology in explaining suffering among patients with chronic illnesses. Methods: Studies included in this qualitative evidence synthesis study were retrieved by searching from the following electronic databases: CINAHL, PubMed Central, and EBSCO. Findings: Phenomenology is regarded as influential to generate in-depth evidence about suffering that are grounded in chronically ill patients' perspectives. The philosophical constructs of suffering suggested fundamental dimensions such as stress, distress, hopelessness, and depression along with pain. Evidence encompasses the entire manifestation of suffering in which all interrelated meanings are understood and referred to a unique structure. Hermeneutic phenomenology was adopted as an effective strategy to elucidate human experience leading to the discovery of the embedded meanings of life experience. Conclusion: The phenomenological approach provides nursing research with the pathway to explore patients' suffering experiences in the chronically ill. PMID- 29582011 TI - Mitigating Burden Associated With Informal Caregiving. AB - Informal caregiving is the most common form of long-term care provided in the United States, and with the projected rapid growth of older adults, informal caregiving will be even more critical in the foreseeable future. In the United States, slightly more than 20% of informal caregivers provide care for more than one care recipient, and 10% provide care for three or more care recipients. Caring for a dependent, older adult patient may have negative effects on physical, psychological, psychosocial, social and financial health of caregivers. Careful assessment of the impact of informal caregiving on the caregiver's functioning is imperative, and will enable a practitioner to not only find ways to help caregivers shoulder the effects of caregiving, but also to measure the effectiveness of interventions that seek to mitigate the effects of caregiving. PMID- 29582012 TI - Improving Patient Experiences and Outcomes Through Personal Care Aide Training. AB - Introduction: The rapidly aging US population is resulting in major challenges including delivering quality care at lower costs in the face of a critical health care workforce shortage. The movement toward home care has dramatically increased the need for qualified, paid personal care aides (PCAs). Adequate PCA training that focuses on skills for person-centered, at home support is an imperative. This study provides evidence that clients of PCAs who have completed a comprehensive, evidence-based PCA training program, titled Building Training...Building Quality (BTBQ), report higher satisfaction and better health outcomes, compared to clients of PCAs with lesser or other training. Methods: A mixed-methods, quasi-experimental design was used to compare self-reported survey responses from clients of BTBQ-trained PCAs (treatment group) with responses from clients of non-BTBQ-trained PCAs (control group). Results: Clients of BTBQ trained PCAs had significantly fewer falls and emergency department visits compared to clients whose PCAs had no BTBQ training (P < .05). Conclusion: BTBQ like PCA training reduces costly adverse events. PMID- 29582013 TI - Occasionally a Patient: Always a Person.

We examined racial differences in clinical and tumor characteristics, treatment and survival in patients diagnosed with breast cancer between 2005 and 2014 at a single institution, the James Cancer Hospital, and who were included in the Arthur G. James Cancer Hospital and Richard J. Solove Research Institute Cancer Registry in Columbus OH. Statistical analyses included likelihood ratio chi square tests for differences in proportions, as well as univariate and multivariate Cox proportional hazards regressions to examine associations between race and overall and progression-free survival probabilities. AA women made up 10.2% (469 of 4593) the sample. Average time to onset of treatment after diagnosis was almost two times longer in AA women compared to white women (62.0 days vs 35.5 days, p < 0.0001). AA women were more likely to report past or current tobacco use, experience delays in treatment, have triple negative and late stage breast cancer, and were less likely to receive surgery, especially mastectomy and reconstruction following mastectomy. After adjustment for confounding factors (age, grade, and surgery), overall survival probability was significantly associated with race (HR = 1.33; 95% CI 1.03-1.72). These findings highlight the need for efforts focused on screening and receipt of prompt treatment among AA women diagnosed with breast cancer.

AB - Aquaporins (AQPs) feature highly selective water transport through cell membranes, where the dipolar orientation of structured water wires spanning the AQP pore is of considerable importance for the selective translocation of water over ions. We recently discovered that water permeability through artificial water channels formed by stacked imidazole I-quartet superstructures increases when the channel water molecules are highly organized. Correlating water structure with molecular transport is essential for understanding the underlying mechanisms of (fast) water translocation and channel selectivity. Chirality adds another factor enabling unique dipolar oriented water structures. We show that water molecules exhibit a dipolar oriented wire structure within chiral I-quartet water channels both in the solid state and embedded in supported lipid bilayer membranes (SLBs). X-ray single-crystal structures show that crystallographic water wires exhibit dipolar orientation, which is unique for chiral I-quartets. The integration of I-quartets into SLBs was monitored with a quartz crystal microbalance with dissipation, quantizing the amount of channel water molecules. Nonlinear sum-frequency generation vibrational spectroscopy demonstrates the first experimental observation of dipolar oriented water structures within artificial water channels inserted in bilayer membranes. Confirmation of the ordered confined water is obtained via molecular simulations, which provide quantitative measures of hydrogen bond strength, connectivity, and the stability of their dipolar alignment in a membrane environment. Together, uncovering the interplay between the dipolar aligned water structure and water transport through the self-assembled I-quartets is critical to understanding the behavior of natural membrane channels and will accelerate the systematic discovery for developing artificial water channels for water desalting. PMID- 29582017 TI - Stabilizing electrochemical interfaces in viscoelastic liquid electrolytes. AB - Electrodeposition is a widely practiced method for creating metal, colloidal, and polymer coatings on conductive substrates. In the Newtonian liquid electrolytes typically used, the process is fundamentally unstable. The underlying instabilities have been linked to failure of microcircuits, dendrite formation on battery electrodes, and overlimiting conductance in ion-selective membranes. We report that viscoelastic electrolytes composed of semidilute solutions of very high-molecular weight neutral polymers suppress these instabilities by multiple mechanisms. The voltage window DeltaV in which a liquid electrolyte can operate free of electroconvective instabilities is shown to be markedly extended in viscoelastic electrolytes and is a power-law function, DeltaV : eta1/4, of electrolyte viscosity, eta. This power-law relation is replicated in the resistance to ion transport at liquid/solid interfaces. We discuss consequences of our observations and show that viscoelastic electrolytes enable stable electrodeposition of many metals, with the most profound effects observed for reactive metals, such as sodium and lithium. This finding is of contemporary interest for high-energy electrochemical energy storage. PMID- 29582018 TI - Critical advancements in achieving high power and stable nonprecious metal catalyst-based MEAs for real-world proton exchange membrane fuel cell applications. AB - Despite great progress in the development of nonprecious metal catalysts (NPMCs) over the past several decades, the performance and stability of these promising catalysts have not yet achieved commercial readiness for proton exchange membrane fuel cells (PEMFCs). Through rational design of the cathode catalyst layer (CCL), we demonstrate the highest reported performance for an NPMC-based membrane electrode assembly (MEA), achieving a peak power of 570 mW/cm2 under air. This record performance is achieved using a precommercial catalyst for which nearly all pores are <3 nm in diameter, challenging previous beliefs regarding the need for larger catalyst pores to achieve high current densities. This advance is achieved at industrially relevant scales (50 cm2 MEA) using a precommercial NPMC. In situ electrochemical analysis of the CCLs is also used to help gain insight into the degradation mechanism observed during galvanostatic testing. Overall, the performance of this NPMC-based MEA has achieved commercial readiness and will be introduced into an NPMC-based product for portable power applications. PMID- 29582019 TI - Truncating SLC5A7 mutations underlie a spectrum of dominant hereditary motor neuropathies. AB - Objective: To identify the genetic cause of disease in 2 previously unreported families with forms of distal hereditary motor neuropathies (dHMNs). Methods: The first family comprises individuals affected by dHMN type V, which lacks the cardinal clinical feature of vocal cord paralysis characteristic of dHMN-VII observed in the second family. Next-generation sequencing was performed on the proband of each family. Variants were annotated and filtered, initially focusing on genes associated with neuropathy. Candidate variants were further investigated and confirmed by dideoxy sequence analysis and cosegregation studies. Thorough patient phenotyping was completed, comprising clinical history, examination, and neurologic investigation. Results: dHMNs are a heterogeneous group of peripheral motor neuron disorders characterized by length-dependent neuropathy and progressive distal limb muscle weakness and wasting. We previously reported a dominant-negative frameshift mutation located in the concluding exon of the SLC5A7 gene encoding the choline transporter (CHT), leading to protein truncation, as the likely cause of dominantly-inherited dHMN-VII in an extended UK family. In this study, our genetic studies identified distinct heterozygous frameshift mutations located in the last coding exon of SLC5A7, predicted to result in the truncation of the CHT C-terminus, as the likely cause of the condition in each family. Conclusions: This study corroborates C-terminal CHT truncation as a cause of autosomal dominant dHMN, confirming upper limb predominating over lower limb involvement, and broadening the clinical spectrum arising from CHT malfunction. PMID- 29582021 TI - Enhancement of Y123 dye-sensitized solar cell performance using plasmonic gold nanorods. AB - The role of the surface plasmon resonance (SPR) of gold nanorods (Au NRs) on the performance of Y123 dye-sensitized solar cells (DSSC) was investigated. DSSCs were fabricated by incorporating different concentrations (0.6 to 3.0 wt%) of Au NRs into TiO2 photoanodes. With an increase in the concentration of the Au NRs, the light absorption by the Y123 dye loaded photoanodes enhanced linearly, but the charge extraction was susceptible to the concentration of the Au NRs. With optimized concentrations (~1.8 wt%) of the Au NRs, the photocurrent of the DSSC enhanced from 12.45 to 15.74 mA cm-2, and the power conversion efficiency (PCE) improved from 5.31 to 8.86%. The DSSC performance was also verified using Au nanoparticles (the PCE was enhanced from 5.31 to 7.72%) for comparison with the Au NR DSSC performance, which demonstrated the advantage of the Au NRs' shape effect with longitudinal SPR due to the modified light interaction. To explain the experimental observations of the plasmonic DSSC, the Au NRs' extinction efficiency and spatial distribution of the near-fields in complete and porous TiO2 media were also estimated using the finite-element method. PMID- 29582020 TI - The Effect of Preoperative Biliary and Pancreatic Drainage on Postoperative Pancreatic Fistula: A Retrospective Cohort Study. AB - Background Surgeons and endoscopists welcome routine preoperative biliary drainage prior to pancreaticoduodenectomy despite evidence that it increases complications. Its effect on postoperative pancreatic fistula is variably reported in literature. Simultaneous biliary and pancreatic drainage is rarely performed for very selected indications and its effects on postoperative pancreatic fistula are largely unknown. Our aim was to analyze the same while eliminating confounding factors. Methods Retrospective single center cohort study of patients who underwent pancreaticoduodenectomy over the past 10 years for carcinoma obstructing the lower common bile duct. Patients who underwent biliary stenting alone, biliary and pancreatic stenting, and no stenting prior to pancreaticoduodenectomy were the three study cohort groups and their records were scrutinized for the incidence of postoperative pancreatic fistula. Results Sixty two patients underwent biliary stenting alone, 5 patients underwent both biliary and pancreatic stenting, and 237 patients were not stented in the adenocarcinoma group without chronic pancreatitis. The pancreatic fistula rate was similar in the patients who underwent biliary stenting alone when compared with the group which was not stented. (24/62 versus 67/237, odds ratio [OR] =0.619, confidence interval (CI) =0.345-1.112, p = 0.121). However, the patients who underwent both biliary and pancreatic stenting had a significant increase in postoperative pancreatic fistula compared with the not stented ( p = 0.003). By univariate and multivariate analysis using Firth logistic regression, pancreatic texture (OR = 1.205, CI = 0.103-2.476, p = 0.032) and the presence of a biliary and pancreatic stent (OR = 2.695, CI = 0.273-7.617, p = 0.027) were the significant factors affecting pancreatic fistula. Conclusion Preoperative biliary drainage alone has no significant influence on postoperative pancreatic fistula except when combined with pancreatic stenting. We need more such studies from other centers to confirm that the rare event of preoperative biliary and pancreatic stenting has indeed this harmful effect on healing of postoperative pancreatic anastomosis. PMID- 29582022 TI - Donor-acceptor cyclopropanes as ortho-quinone methide equivalents in formal (4 + 2)-cycloaddition to alkenes. AB - A new type of donor-acceptor cyclopropane reactivity towards alkenes was revealed for 2-arylcyclopropane-1,1-diesters that contain an OH-group in the ortho position of the aryl substituent. In this case, the initial cyclopropanes participate in formal (4 + 2)-cycloaddition as synthetic equivalents of ortho quinone methides which are potential intermediates generated under mild conditions in the presence of a Lewis acid. PMID- 29582023 TI - Lewis acid-catalyzed enantiospecific [3 + 2] annulations of gamma-butyrolactone fused cyclopropanes with aromatic aldehydes: synthesis of chiral furanolignans. AB - An enantiospecific [3 + 2] annulation of gamma-butyrolactone fused cyclopropanes with aromatic aldehydes was realized under Lewis acid catalysis. This method provides facile access to a series of chiral furanolignan derivatives bearing multiple contiguous stereogenic centers in good-to-excellent yields, exclusive diastereoselectivities and excellent enantiopurities under mild reaction conditions. Elaboration work on the product of this reaction delivers stereoisomeric analogues of (+)-virgatusin and suggests a structural revision might be necessary for a previously reported isolated natural product. PMID- 29582025 TI - Tuning antimicrobial properties of biomimetic nanopatterned surfaces. AB - Nature has amassed an impressive array of structures that afford protection from microbial colonization/infection when displayed on the exterior surfaces of organisms. Here, controlled variation of the features of mimetics derived from etched silicon allows for tuning of their antimicrobial efficacy. Materials with nanopillars up to 7 MUm in length are extremely effective against a wide range of microbial species and exceed the performance of natural surfaces; in contrast, materials with shorter/blunter nanopillars (<2 MUm) selectively killed specific species. Using a combination of microscopies, the mechanisms by which bacteria are killed are demonstrated, emphasizing the dependence upon pillar density and tip geometry. Additionally, real-time imaging reveals how cells are immobilized and killed rapidly. Generic or selective protection from microbial colonization could be conferred to surfaces [for, e.g., internal medicine, implants (joint, dental, and cosmetic), food preparation, and the agricultural industry] patterned with these materials as coatings. PMID- 29582024 TI - Microscale mapping of extracellular matrix elasticity of mouse joint cartilage: an approach to extracting bulk elasticity of soft matter with surface roughness. AB - Cartilage is composed of cells and an extracellular matrix, the latter being a composite of a collagen mesh interpenetrated by proteoglycans responsible for tissue osmotic swelling. The matrix composition and structure vary through the tissue depth. Mapping such variability requires tissue sectioning to gain access. The resulting surface roughness, and concomitant proteoglycan loss contribute to large uncertainties in elastic modulus estimates. To extract elasticity values for the bulk matrix which are not obfuscated by the indeterminate surface layer, we developed a novel experimental and data analysis methodology. We analyzed the surface roughness to optimize the probe size, and performed high-resolution (1 MUm) elasticity mapping on thin (~12 MUm), epiphyseal newborn mouse cartilage sections cut parallel to the bone longitudinal axis or normal to the articular surface. Mild fixation prevented the major proteoglycan loss observed in unfixed specimens but not the stress release that resulted in thickness changes in the sectioned matrix. Our novel data analysis method introduces a virtual contact point as a fitting parameter for the Hertz model, to minimize the effects of surface roughness and corrects for the finite section thickness. Our estimates of cartilage elasticity converge with increasing indentation depth and, unlike previous data interpretations, are consistent with linearly elastic material. A high cell density that leaves narrow matrix septa between cells may cause the underestimation of elastic moduli, whereas fixation probably causes an overestimation. The proposed methodology has broader relevance to nano- and micro indentation of soft materials with multiple length scales of organization and whenever surface effects (including roughness, electrostatics, van der Waals forces, etc.) become significant. PMID- 29582026 TI - Light trapping in thin film silicon solar cells via phase separated disordered nanopillars. AB - In this work, we have improved the absorption properties of thin film solar cells by introducing light trapping reflectors deposited onto self-assembled nanostructures. The latter consist of a disordered array of nanopillars and are fabricated by polymer blend lithography. Their broadband light scattering properties are exploited to enhance the photocurrent density of thin film devices, here based on hydrogenated amorphous silicon active layers. We demonstrate that these light scattering nanopillars yield a short-circuit current density increase of +33%rel with respect to equivalent solar cells processed on a planar reflector. Moreover, we experimentally show that they outperform randomly textured substrates that are commonly used for achieving efficient light trapping. Complementary optical simulations are conducted on an accurate 3D model to analyze the superior light harvesting properties of the nanopillar array and to derive general design rules. Our approach allows one to easily tune the morphology of the self-assembled nanostructures, is up-scalable and operated at room temperature, and is applicable to other photovoltaic technologies.

AB - In this paper we report the synthesis and single-crystal X-ray characterisation of six novel indium(iii) xanthate complexes. These xanthates have been used as an In-source for the synthesis of highly crystalline CuInS2 nanoparticles in conjunction with a Cu(i)-xanthate. In synthesising the nanoparticles we have also demonstrated an ability to control the phase of the material through choice of solvent. PMID- 29582028 TI - MOF-derived nanohybrids for electrocatalysis and energy storage: current status and perspectives. AB - More than 20 000 MOFs have been reported to date, with different combinations of metal ions/centers and organic linkers, and they can be grown into various 3D, 2D, 1D and 0D morphologies. The flexibility in control over varying length scales from atomic scale up to bulk structure allows access to an almost endless variety of MOF-based and MOF-derived materials. Indeed, MOFs themselves have been studied as a class of useful functional materials. More remarkably, extensive research conducted in recent years has shown that MOFs are exceptionally good precursors for a large variety of nanohybrids as active materials in both electrocatalysis and energy storage. As they already contain both carbon and well-dispersed metal atoms, MOFs can be converted to conductive carbons decorated with active metal species and doping elements through appropriate pyrolysis. Due to the great diversity accessible in the composition, structure, and morphology of MOFs, several types of MOF-derived nanohybrids are now among the best performing materials both for electrocatalysts and electrodes in various energy conversion and storage devices. In addition to mesoporous nano-carbons, both doped and undoped, carbon-metal nanohybrids, and carbon-compound nanohybrids, there are several types of core@shell, encapsulated nanostructures, embedded nanosystems and heterostructures that have been developed from MOFs recently. They can be made in either free-standing forms, nano- or micro-powders, grown on appropriate conducting substrates, or assembled together with other active materials. During the MOF to active material conversion, other active species or precursors can be inserted into the MOF-derived nanostructures or assembled on surfaces, leading to uniquely new porous nanostructures. These MOF-derived active materials for electrocatalysis and energy storage are nanohybrids consisting of more than functional components that are purposely integrated together at desired length scales for much-improved performance. This article reviews the current status of these nanohybrids and concludes with a brief perspective on the future of MOF derived functional materials. PMID- 29582029 TI - Salen-indium/triarylborane triads: synthesis and ratiometric emission-colour changes by fluoride ion binding. AB - Salen-based indium triads, [{(3-tBu)2-(5-Mes2B)2-salen}In-Me] (1) and [{(3-tBu)2 (5-Mes2Bphenyl)2-salen}In-Me] (2), bearing triarylborane (TAB) units were prepared and fully characterised by NMR spectroscopy and elemental analysis. The major absorption bands of 1 and 2 appeared in the region centred at 347 nm and 374 nm, respectively, and the intense emission spectra were observed in the sky blue (lambdaem = 491 nm for 1) and bluish-green (lambdaem = 498 nm for 2) regions, respectively. The solvatochromism effects in various organic solvents and computational calculation results strongly suggested that these absorption and emission features are mainly attributed to intramolecular charge transfer (ICT) transitions between the salen ligand moieties and the TAB units. Furthermore, UV-vis and photoluminescence (PL) titration experiments by the addition of fluoride anions demonstrated ratiometric quenching patterns in both the absorption and emission spectra, indicating that binding of the fluoride anion to the boron centres interrupts these ICT transitions in each compound. Interestingly, both triads exhibited a gradual red-shifted response in each emission spectrum upon the addition of the fluoride anions, resulting in a dramatic colour-change to yellow. The computational calculation results of the S1 states revealed that these emission-colour change properties arise from the elevation of HOMO levels, which are mainly localised on the TAB moieties, resulting from the fluoride anion binding to the borane centres. PMID- 29582030 TI - Does Rashba splitting in CH3NH3PbBr3 arise from 2 * 2 surface reconstruction? AB - As a result of early theoretical predictions, evidence for the Rashba or Dresselhaus effect in hybrid perovskites has recently attracted several experimental investigations, motivated by possible applications in spin orbitronics. For instance, a large Rashba splitting has recently been reported for the (001) surface of CH3NH3PbBr3. This effect is forbidden in the bulk material since both low-temperature and room-temperature crystal structures present inversion symmetry. Here we investigate the effects of two (001) nanoscale surface reconstructions of CH3NH3PbBr3 using first-principles approaches based on density functional theory (DFT). The two experimental reconstructions are related to different orientations of MA cations at the surface, defining zigzag and dimer phases. The impact of these structural transformations on their electronic structures is thoroughly investigated. Whereas calculations reveal the occurrence of surface-induced Rashba effect, its amplitude is considerably smaller than the experimentally reported value, in agreement with other experimental investigations and leading to the conclusion that mesoscale surface polar domains and/or surface defects may result from sample preparation. PMID- 29582031 TI - Variable temperature NMR of organogelators: the intensities of a single sample describe the full phase diagram. AB - Organogelators constitute a numerous class of compounds, able to form gels in organic solvents. Their phase diagrams are useful to understand their mechanisms of formation and their stability, but their mapping is often a tedious task. We show that liquid NMR can simplify and quicken the acquisition of phase diagrams. In liquid NMR spectra of organogels, the visible signals of the gelator represent only its soluble fraction. The intensities increase with temperature, until the gel melts. Suitable normalization of these intensities yields the solubility as a function of temperature, which is sufficient to map the phase diagram. We verified it experimentally with three organogelators, chosen because independent authors have previously mapped out their phase diagram by other techniques including DSC and rheology. We show that the curves obtained by NMR superimpose with these diagrams. A variable temperature NMR experiment with a single sample can yield the phase diagram with sensitivity of the order of 0.01 wt%. PMID- 29582032 TI - An in situ DRIFTS mechanistic study of CeO2-catalyzed acetylene semihydrogenation reaction. AB - CeO2-Catalyzed C2H2 semihydrogenation reaction is a newly emerging catalytic reaction, but the reaction mechanism is not established. We herein report a comprehensive mechanistic study by in situ diffuse reflectance infrared Fourier transformed spectroscopy. Various types of surface species were observed to form upon C2H2 and C2H4 adsorption on CeO2 at different temperatures, including molecularly-adsorbed pi-bonded and di-sigma-bonded species, dissociatively adsorbed species of C2H and C2H3, carbonates and formate species, and oligomers species, respectively. During the C2H2 semihydrogenation reaction, the CeO2 surface is partially reduced and strongly hydroxylated. Both O and Ce sites on CeO2 are capable of catalyzing C2H2 semihydrogenation reaction to C2H4, and the O site is more active than the Ce site. The reaction mechanism was elucidated with observed molecularly-adsorbed C2H2 species, a C2H3 intermediate and adsorbed C2H4 species on CeO2. The pi-bonded C2H2 species at the O site was identified as the dominant active surface species for CeO2-catalyzed C2H2 semihydrogenation reaction. These results greatly advance the fundamental understanding of CeO2 catalyzed C2H2 semihydrogenation reaction. PMID- 29582033 TI - Refugee health - collaborating for better outcomes. PMID- 29582034 TI - Helping refugees build new lives: from consultation to collaboration. AB - Professor Peter Shergold was appointed as the New South Wales (NSW) Coordinator General for Refugee Resettlement in 2015, providing him with an opportunity to reimagine how the not-for-profit, public and private sectors could collaborate to improve the wellbeing of refugees settling in NSW, Australia. Through collaboration, NSW agencies are shifting the service response from one that is reactive to refugees' immediate settlement needs towards an investment approach that creates employment pathways. By identifying and building on refugees' strengths, resilience and human capital, Professor Shergold believes NSW can deliver better outcomes for both refugees and the communities they live in. PHRP asked him about his role, its objectives and its achievements. PMID- 29582035 TI - Integration of refugees into routine primary care in NSW, Australia. AB - Refugees have complex physical, psychological and social needs that are challenging to manage comprehensively in primary care. In recent years, many refugees settling in Australia have been sponsored by family members. Although they may receive settlement support, these new arrivals may not be assessed or managed by specialised refugee health services. Their sponsors usually link them to bilingual general practitioners, but these doctors may not be aware of or have access to a comprehensive range of services. There is an urgent need for more integrated health service provision for people from refugee backgrounds, based on trust and communication. This requires change at the practice, local service and system level. PMID- 29582036 TI - Canada's response to refugees at the primary health care level. AB - Responsive primary health care systems and services must be at once complex and nimble. Policy makers may wish to believe that existing health systems effectively care for all populations equally, including refugees. However, we know that refugees may require a health equity approach: an approach where all levels of government, all types of health practitioners, and even the public sector, participate to ensure access to effective primary health care. This article outlines some of Canada's healthcare responses for refugee populations. We provide field examples and guidelines that demonstrate responses, as well as ongoing inconsistencies and limitations. Refugee-receiving countries such as Australia, the US and Canada all have stories of success in resettlement and health systems. This article will focus on Canada. PMID- 29582038 TI - Transition from an asylum seeker-specific health service to mainstream primary care for community-based asylum seekers: a qualitative interview study. AB - BACKGROUND AND AIM: Transition of asylum seekers from special-purpose health services to mainstream primary care is both necessary and difficult. This study explores the issues encountered by asylum seekers undergoing this transition in Sydney, Australia. METHODS: Qualitative semistructured interviews were conducted with nine asylum seeker patients and nine staff working in the sector. RESULTS: Asylum seekers faced significant challenges in the transition to mainstream primary care. Contributing factors included the complexity of health and immigration systems, the way in which asylum seeker-specific services provide care, lack of understanding and accommodation by mainstream general practioner (GP) services, asylum seekers' own lack of understanding of the health system, mental illness, and social and financial pressures. CONCLUSIONS: There is a need for better preparation of asylum seekers for the transition to mainstream primary care. Mainstream GPs and other providers need more education and support so that they can better accommodate the needs of asylum seeker patients. This is an important role for Australia's refugee health services and Primary Health Networks. PMID- 29582037 TI - Blood screen findings in a 2-year cohort of newly arrived refugees to Sydney, Australia. AB - OBJECTIVES: To describe the prevalence of certain health conditions in newly arrived refugees to Sydney, Australia, and thereby help inform screening practices. STUDY TYPE: A clinical audit of routinely collected pathology results. METHODS: Demographics and pathology results from a nurse-led health assessment program for newly arrived refugees during 2013 and 2014 were analysed. Prevalences of screened conditions were calculated, and compared by country of birth and other demographic features. A specific category was created for those from Middle Eastern countries, for comparative analysis. RESULTS: Pathology results were analysed for 3307 people from 4768 seen by the assessment program (69.4%). Anaemia was found in 6% of males and 7.6% of females. Vitamin D deficiency (<50 nmol/L) was detected in 77.5%. Chronic hepatitis B was found in only 1.7% but in more than 10% of people from Burmese and Tibetan backgrounds. Strongyloides seropositivity was found in 4%. Among the subset tested for hepatitis C antibody, 0.5% were positive. No human immunodeficiency virus (HIV) infections were detected. More than 75% of the study population was from Middle Eastern countries. Compared with refugees from other regions, this subset had less anaemia (in females), more vitamin D deficiency, less chronic hepatitis B and less strongyloides seropositivity. CONCLUSIONS: People from refugee backgrounds have differing risks of conditions, based on demographics, migration history and prior screening. Postarrival testing should be tailored to each family and individual. Results of screening should be constantly reviewed and the approach updated based on findings. We support, in particular, the Canadian approach of only retesting HIV in refugees from countries with a high prevalence of infection (>1%). PMID- 29582039 TI - Violence against ambulance personnel: a retrospective cohort study of national data from Safe Work Australia. AB - : Objectives and importance: Paramedics have high rates of occupational injury and fatality. The objective of this study is to describe their specific risks of violence-related injury. STUDY TYPE: This retrospective cohort study is an examination of retrospective data provided by Safe Work Australia (SWA). METHODS: An examination of the 300 cases of serious claims of injury related to assaults, violence, harassment and bullying that occurred among individuals identified as ambulance officers and paramedics in Australia from 2001 to 2014. Paramedic risks likely vary by exposures such as hours worked and call volume. To examine how those exposures may influence risk, the available data were used to estimate rates based on hours worked and call volume. RESULTS: The data show that, for serious injuries among paramedics in Australia between 2001 and 2014, the total number of violence-related cases increased from 5 to 40 per year; the number of cases of injury secondary to assault tripled from 10 to 30; and the rate of cases by call volume doubled from 6 to 12. The cost of these injuries was approximately AUD$250 000 for the year 2013-14. The median time at work lost per individual case of 'work-related harassment and/or workplace bullying' was 9.6 weeks. Although females comprised 32% of the paramedic workforce, they were the victims in 42% of cases of exposure to violence and 40% of harassment cases. CONCLUSIONS: Although anecdotal reports indicate that some interventions have been attempted, violence against paramedics continues to be a growing problem in Australia. The data presented in this study allow for a better understanding of the problem and can support efforts by ambulance service administrators, physicians, paramedics and university researchers to work together to develop and publish evidence based, cost-effective solutions to reduce the risk of workplace violence. Effective solutions will likely be multifaceted and include training, engineering changes, community education and adjustments to agency policies. Because of the widespread nature of the risks, a national commission should be empowered to address this growing problem. PMID- 29582040 TI - Insights from linking routinely collected data across Australian health jurisdictions: a case study of end-of-life health service use. AB - OBJECTIVES: The jurisdictional nature of routinely collected health data in Australia has created challenges for linking data across state/territory and federal government boundaries. This has impeded understanding of the interplay between service use across hospital and community care. Our objective was to demonstrate the value-add of cross-jurisdictional data using a case study of health service use and the factors associated with healthcare use towards the end of life. STUDY TYPE: Retrospective cohort study using routinely collected health data. METHODS: We used two decedent cohorts of people aged >=65 years who died in New South Wales (NSW), Australia, in 2006 or 2007. The population cohort comprised the general NSW population linked to NSW data collections; the other cohort comprised Australian Government Department of Veterans' Affairs (DVA) clients (with full healthcare entitlements) linked to NSW and Commonwealth data. We compared information available on health services received during the last 6 months of life and ran multivariable analyses for both cohorts to demonstrate the added value of the Commonwealth data. RESULTS: We included 37 567 decedents in the population cohort and 11 259 in the DVA cohort. Cancer was the cause of death for 27% of the NSW cohort and 22% of the DVA cohort; approximately 40% of decedents in each cohort had a cancer history. We summarise information on hospital services for both cohorts and examine community care (general practitioner consultations, specialist presentations, prescriptions dispensed) for the DVA cohort only. Multivariable analyses in the DVA cohort demonstrated that high rates of emergency department (ED) presentations and hospitalisation were associated with higher rates of use of all health services, including community care. Use of primary care did not reduce ED or hospital use. We were not able to examine the interplay between community and hospital care in the NSW population cohort. CONCLUSIONS: In our case study, we demonstrated the value-add of Commonwealth data for understanding the drivers of hospital services use, which has implications for service delivery and resource allocation. There is an abundance of routinely collected health data in Australia that can be used to describe whole-of-healthcare use for a broad range of issues. PMID- 29582041 TI - Psychostimulant-related health service demand in an inner-city hospital, 2012 2015. AB - OBJECTIVE: To analyse routinely collected data from a hospital database of drug health consultation-liaison (CL) assessments. We aimed to investigate changes in psychostimulant-related health service demand in an inner-city hospital to inform the development of locally appropriate models of care. METHODS: We used de identified drug health CL service data from 2012 to 2015. Psychostimulant-related consultations and admissions were compared with opioid-related consultations and admissions over time, by sex and by ward type (medical units, mental health units or emergency department). RESULTS: The CL service collected information on 8800 consultations and 4405 hospital admissions from 2012 to 2015. Psychostimulant use was responsible for 684 (7.8%) consultations and 372 (8.4%) admissions. Opioids were related to 1914 (21.8%) consultations and 864 (19.6%) admissions. Psychostimulants were the subject of three times more consultations in 2015 than in 2012, and more than twice as many admissions. Time trend analysis showed a significant time effect for consultations and admissions relating to psychostimulants. Conversely, no significant changes were observed in consultations and admissions relating to opioids. CONCLUSION: This study identified a rapid rise in the demand for psychostimulant-related inpatient assessments, suggesting the use of these drugs has increased locally. Because of the impact on the public health system, there is a need to invest in and implement new treatment strategies and services for psychostimulant users.

AB - As outlined in the Department of Immigration and Border Protection Annual report 2016-17, Australia granted 21 928 humanitarian visas in 2016-17, 13 760 of them offshore. This number will increase in future to a planned offshore program of 18 750 in 2018-19. The report notes that the United Nations High Commissioner for Refugees ranks Australia third for the number of refugees resettled. With such a massive program and commitment by the Australian Government, the need to ensure that health and wellbeing are maintained or gained during the settlement process is paramount. This article outlines how collaboration between like-minded national governments can improve premigration health screening through information sharing, collaborative learning and increased capability in countries of origin to not only screen for illness and disability, but to more effectively put measures in place to address these before, during and after arrival. Australia, Canada, New Zealand, the UK and the US have worked together for more than a decade on migration health screening policies to ensure better management of health needs and successful resettlement. A case study about the Syrian refugee cohort, which began arriving in Australia in late 2015, illustrates how intergovernmental collaboration can improve settlement.

AB - Purpose: Word selection has typically been thought of as an inactive ingredient in phonological treatment, but emerging evidence suggests that word selection is an active ingredient that can impact phonological learning. The goals of this tutorial are to (a) review the emerging single-subject evidence on the influence of word characteristics on phonological learning in clinical treatment, (b) outline hypotheses regarding the mechanism of action of word characteristics, and (c) provide resources to support clinicians incorporating word selection as an active ingredient in their approach to phonological treatment. Method: Research demonstrating the influence of the word frequency, neighborhood density, age of acquisition, and lexicality of treatment stimuli on phonological learning is summarized. The mechanism of action for each characteristic is hypothesized. Methods from the research studies are used to create a free set of evidence-based treatment materials targeting most of the mid-8 and late-8 consonants. Results: Clinicians have numerous evidence-based options to consider when selecting stimuli for phonological treatment including (a) high-frequency and high-density words, (b) low-frequency and high-density words, (c) high-frequency and mixed density words, (d) low-frequency and late-acquired words, and (e) nonwords. Conclusion: Incorporating word characteristics into phonological treatment may boost phonological learning. KU ScholarWorks Supplemental Material: http://hdl.handle.net/1808/24768. PMID- 29582052 TI - The Complexity Approach to Phonological Treatment: How to Select Treatment Targets. AB - Purpose: There are a number of evidence-based treatments for preschool children with phonological disorders (Baker & McLeod, 2011). However, a recent survey by Brumbaugh and Smit (2013) suggests that speech-language pathologists are not equally familiar with all evidence-based treatment alternatives, particularly the complexity approach. The goal of this clinical tutorial is to provide coaching on the implementation of the complexity approach in clinical practice, focusing on treatment target selection. Method: Evidence related to selecting targets for treatment based on characteristics of the targets (i.e., developmental norms, implicational universals) and characteristics of children's knowledge of the targets (i.e., accuracy, stimulability) is reviewed. Free resources are provided to aid clinicians in assessing accuracy and stimulability of singletons and clusters. Use of treatment target selection and generalization prediction worksheets is illustrated with 3 preschool children. Results: Clinicians can integrate multiple pieces of information to select complex targets and successfully apply the complexity approach to their own clinical practice. Conclusion: Incorporating the complexity approach into clinical practice will expand the range of evidence-based treatment options that clinicians can use when treating preschool children with phonological disorders.

PMID- 29582053 TI - Adeno-Associated Viral Vector (Serotype 2)-Nerve Growth Factor for Patients With Alzheimer Disease: A Randomized Clinical Trial. AB - Importance: Nerve growth factor (NGF) is an endogenous neurotrophic factor that prevents the death and augments the functional state of cholinergic neurons of the basal forebrain, a cell population that undergoes extensive degeneration in Alzheimer disease (AD). Objective: To determine whether stereotactically guided intracerebral injections of adeno-associated viral vector (serotype 2)-nerve growth factor (AAV2-NGF) are well tolerated and exhibit preliminary evidence of impact on cognitive decline in mild to moderate AD-associated dementia. Design, Setting, and Participants: In a multicenter phase 2 trial, 49 participants with mild to moderate AD were randomly assigned in a 1:1 ratio to receive stereotactically guided intracerebral injections of AAV2-NGF or sham surgery. Participants were enrolled between November 2009 and December 2012. Analyses began in February 2015. The study was conducted at 10 US academic medical centers. Eligibility required a diagnosis of mild to moderate dementia due to AD and individuals aged 55 to 80 years. A total of 39 participants did not pass screening; the most common reason was Mini-Mental State Examination scores below cutoff. Analyses were intention-to-treat. Interventions: Stereotactically guided intracerebral injections of AAV2-NGF into the nucleus basalis of Meynert of each hemisphere or sham surgery. Main Outcomes and Measures: Change from baseline on the Alzheimer's Disease Assessment Scale-cognitive subscale at month 24. Results: Among 49 participants, 21 (43%) were women, 42 (86%) self-identified as white, and the mean (SD) age was 68 (6.4) years. AAV2-NGF was safe and well-tolerated through 24 months. No significant difference was noted between the treatment group and placebo on the primary outcome measure, the Alzheimer's Disease Assessment Scale-cognitive subscale (mean [SD] score, 14.52 [4.66] vs 9.11 [4.65], P = .17). Conclusions and Relevance: This multicenter randomized clinical trial demonstrated the feasibility of sham-surgery-controlled stereotactic gene delivery studies in patients with AD. AAV2-NGF delivery was well-tolerated but did not affect clinical outcomes or selected AD biomarkers. Pathological confirmation of accurate gene targeting is needed.

PMID- 29582054 TI - Office-Based Screening for Dementia in Parkinson Disease: The Montreal Parkinson Risk of Dementia Scale in 4 Longitudinal Cohorts. AB - Importance: Parkinson disease dementia dramatically increases mortality rates, patient expenditures, hospitalization risk, and caregiver burden. Currently, predicting Parkinson disease dementia risk is difficult, particularly in an office-based setting, without extensive biomarker testing. Objective: To appraise the predictive validity of the Montreal Parkinson Risk of Dementia Scale, an office-based screening tool consisting of 8 items that are simply assessed. Design, Setting, and Participants: This multicenter study (Montreal, Canada; Tottori, Japan; and Parkinson Progression Markers Initiative sites) used 4 diverse Parkinson disease cohorts with a prospective 4.4-year follow-up. A total of 717 patients with Parkinson disease were recruited between May 2005 and June 2016. Of these, 607 were dementia-free at baseline and followed-up for 1 year or more and so were included. The association of individual baseline scale variables with eventual dementia risk was calculated. Participants were then randomly split into cohorts to investigate weighting and determine the scale's optimal cutoff point. Receiver operating characteristic curves were calculated and correlations with selected biomarkers were investigated. Main Outcomes and Measures: Dementia, as defined by Movement Disorder Society level I criteria. Results: Of the 607 patients (mean [SD] age, 63.4 [10.1]; 376 men [62%]), 70 (11.5%) converted to dementia. All 8 items of the Montreal Parkinson Risk of Dementia Scale independently predicted dementia development at the 5% significance level. The annual conversion rate to dementia in the high-risk group (score, >5) was 14.9% compared with 5.8% in the intermediate group (score, 4-5) and 0.6% in the low risk group (score, 0-3). The weighting procedure conferred no significant advantage. Overall predictive validity by the area under the receiver operating characteristic curve was 0.877 (95% CI, 0.829-0.924) across all cohorts. A cutoff of 4 or greater yielded a sensitivity of 77.1% (95% CI, 65.6-86.3) and a specificity of 87.2% (95% CI, 84.1-89.9), with a positive predictive value (as of 4.4 years) of 43.90% (95% CI, 37.76-50.24) and a negative predictive value of 96.70% (95% CI, 95.01-97.85). Positive and negative likelihood ratios were 5.94 (95% CI, 4.08-8.65) and 0.26 (95% CI, 0.17-0.40), respectively. Scale results correlated with markers of Alzheimer pathology and neuropsychological test results. Conclusions and Relevance: Despite its simplicity, the Montreal Parkinson Risk of Dementia Scale demonstrated predictive validity equal or greater to previously described algorithms using biomarker assessments. Future studies using head-to-head comparisons or refinement of weighting would be of interest. PMID- 29582056 TI - Educational Intervention in a Medically Underserved Area. AB - Context: Medical students from rural and medically underserved areas (MUAs) are more likely than their peers to practice medicine in rural areas and MUAs. However, students from MUAs are also more likely to face socioeconomic barriers to a career in medicine. Objective: To determine whether a week-long summer enrichment experience (SEE) at Edward Via College of Osteopathic Medicine Carolinas could successfully teach high school students from MUAs basic biomedical concepts and foster an interest in medicine and the health sciences. Methods: The SEE program is open to high school students in the Spartanburg, South Carolina, area. The program includes interactive lectures, laboratories, demonstrations on gross anatomy prosections, demonstrations on medical simulation models, tours of emergency vehicles, an introduction to osteopathic manipulative medicine, and student-led research projects. Participants were asked to complete a 15-question quiz that assessed their knowledge of basic biomedical concepts and a 10-question survey that assessed their attitudes toward careers in medicine and health sciences. Both the quiz and the survey were completed on both the first and final days of the program. The data were analyzed using paired t tests. Results: Participant knowledge of basic biomedical concepts, as determined by the quiz scores, increased after completion of the program (9.1 average correct answers vs 12.6 average correct answers) (P<.001). Participant attitude toward medicine and the health sciences improved in 9 of the 10 items surveyed after completion of the program (P<.05). Conclusions: Participant knowledge of basic biomedical concepts and their knowledge of and interest in careers in the health sciences improved after completing the SEE program. These findings suggest that educational interventions for high school students could help to develop primary care physicians for rural areas and MUAs and that there is a role for osteopathic medical schools to nurture these students as early as possible. PMID- 29582057 TI - Factors Associated With Osteopathic Primary Care Residency Choice Decisions. AB - Context: The osteopathic medical profession traditionally emphasized the education of primary care physicians. A common thread for both osteopathic and allopathic residency matches, however, has been an increase in the interest in specialties outside of primary care. Objective: To determine whether there are critical points in medical school associated with residency selection decision making, what factors affect residency selection decisions, and whether any identifiable shifts or trends exist. Methods: This mixed-methods study sequentially used qualitative and quantitative research approaches. The study population was a convenience sample of osteopathic medical students, interns and residents, and practicing physicians from partner medical schools, associated hospitals, and a regional association of osteopathic physicians. In the first phase, interviews and focus group discussions were analyzed for codes, categories, and themes relating to factors that influence residency selection. In the second phase, a survey was created from the results of the first phase and administered to study participants. Results: Of the 3450 potential participants, 282 completed the survey. Ninety-one of 209 participants (43.5%) indicated that the third year of medical school was the time they will or did decide what type of residency program to pursue. There were no significant differences in the mean scores between the respondent groups (ie, students, residents, and physicians) when ranking the importance of the 10 influential factors associated with residency selection decision-making (P>.05 for all). Conclusion: The highest percentage of participants indicated the third year of medical school was the time that they made residency selection decisions regarding what specialty they were interested in entering. No shifts regarding the importance of specific primary care residency choice factors were found between training status of respondents. PMID- 29582058 TI - Interprofessional Collaborative Practice: Use of Simulated Clinical Experiences in Medical Education. AB - Context: Mastering the art of assessing interprofessional outcomes has been a topic of interest in academic research. Specifically, the Interprofessional Education Collaborative has been publishing thorough bodies of work that aim to strengthen teamwork among health professionals and reinforce competencies that will lead to better patient care. Objective: To determine osteopathic medical students' perceived effectiveness of simulated clinical experiences in cultivating interprofessional competencies with nursing students. Methods: Second year osteopathic medical students (classes of 2016 and 2017) and nursing students participated in a simulated clinical experience using a simulated patient mannequin. Students were assessed on clinical and humanistic skills using graded evaluations performed by faculty and actors portraying family members and given feedback on their performance. Evaluation grades were not analyzed. Students were asked to complete an anonymous survey that assessed their attitudes toward the collaborative experience. Results: A total of 743 medical students participated in the study-371 from the class of 2016 and 372 from the class of 2017. Incomplete surveys (1 from the class of 2016 and 3 from the class of 2017) were included in the analysis. Statistically significant differences were found between the 2 classes of medical students in their responses to 2 items. With regard to appropriate patient data collection, the ranked distribution of scores was significantly greater for the class of 2014-2015 than for the class of 2013 2014 (mean rank, 389.3 vs 354.64, respectively; U=75,445.50; P=.017). For the item on effective communication with family members, the ranked distribution of scores was significantly greater for the class of 2014-2015 than for the class of 2013-2014 (mean rank, 390.61 vs 353.34, respectively; U=75,928.50; P=.006). Overall, medical students reported feeling better prepared to care for real patients after the simulation. Conclusion: Simulated interprofessional experiences during the second year of medical school may help prepare students to collaborate with other health care professionals in a clinical setting, take care of patients, and communicate with patients' family members. PMID- 29582059 TI - Assessment Considerations for Core Entrustable Professional Activities for Entering Residency. AB - Context: In the process of analyzing entrustable professional activities (EPAs) for use in medical education, ten Cate and others identified challenges, including the need for valid and reliable EPA assessment strategies. Objective: To provide osteopathic medical schools with a database of assessment tools compiled from the literature to assist them with the development and implementation of robust, evidence-based assessment methods. Methods: MEDLINE, ERIC, PubMed, and other relevant databases were searched using MeSH keywords for articles outlining robust, evidence-based assessment tools that could be used in designing assessments for EPAs 1 through 6. Results: A total of 55 publications were included in content analysis and reporting. All but 2 of the assessment articles were conducted in an undergraduate or graduate medical education setting. The majority of the 55 articles related to assessment of competencies affiliated with EPA 2 (16 articles) and EPA 4 (15 articles). Four articles focused on EPA 3. Conclusion: Osteopathic medical schools can use this database of assessment tools to support the development of EPA-specific assessment plans that match the unique context and needs of their institution. PMID- 29582060 TI - Resident and Faculty Attitudes Toward Osteopathic-Focused Education. AB - Context: The transition period for the single accreditation system for graduate medical education under the Accreditation Council for Graduate Medical Education (ACGME) began on July 1, 2015, and will end June 30, 2020. As of February 5, 2018, 82.6% of residency programs accredited by the American Osteopathic Association (AOA) have applied for or achieved ACGME accreditation and 160 programs have applied for or achieved osteopathic recognition. Objective: To assess baseline attitudes of osteopathic and allopathic faculty and residents in AOA-accredited and dually accredited residency programs regarding the value of osteopathic-focused educational curricula and mentors. Methods: A survey was emailed to 60 program directors of AOA-accredited programs and dually accredited residency programs, some of which had obtained ACGME osteopathic recognition. The survey was to be completed by residents and faculty. Items were formulated to obtain baseline measurements regarding the level of awareness of osteopathic principles and practice (OPP), attitudes regarding osteopathic culture, and the weighted importance of aspects of the osteopathic curriculum. Principal components analysis with Varimax rotation was used. Comparison analysis was accomplished by either independent t tests for subscale scores or Mann-Whitney U tests for item-level scores. Results: A total of 327 people responded to the survey (115 faculty members, 211 residents, and 1 no response). Of the 60 program directors contacted, 53 replied with at least 1 program representative. One hundred twenty-nine of all 211 residents (61.7%), including 107 of 134 osteopathic family medicine residents (79.9%), agreed that they intended to use OMT when in practice. The curricular component item with the lowest total survey score, indicating the highest-ranked level of importance, was the ability to work with osteopathic faculty (mean [SD], 1.98 [0.98]). Of the items measuring osteopathic awareness, statements with the strongest level of agreement from all respondents were "I have seen OMT performed on a patient or a peer" and "I am familiar with the basic tenets of OPP." Conclusion: Residents in AOA-accredited programs value osteopathic mentors and OMT, and they generally intend to use OMT when in practice. Respondents from programs with osteopathic recognition had more favorable attitudes toward osteopathic culture and curriculum than did respondents from programs without osteopathic recognition. PMID- 29582061 TI - Single Accreditation System Update: A Year of Progress. AB - In 2014, the American Osteopathic Association (AOA), the American Association of Colleges of Osteopathic Medicine, and the Accreditation Council for Graduate Medical Education (ACGME) agreed to establish a new, single accreditation system for graduate medical education in the United States. The 5-year transition period, from July 1, 2015, through June 30, 2020, gives AOA training programs time to apply for and receive ACGME accreditation before the AOA ceases its postdoctoral accreditation functions. This article discusses policies to protect osteopathic residents during training, addresses program size, reviews progress at the midpoint of the 5-year transition, and looks at next steps in the establishment of the single accreditation system.

AB - Importance: In recent years, rates of vaccination have been declining. Whether this phenomenon disproportionately affects children with autism spectrum disorder (ASD) or their younger siblings is unknown. Objectives: To investigate if children after receiving an ASD diagnosis obtain their remaining scheduled vaccines according to the Advisory Committee on Immunization Practices (ACIP) recommendations and to compare the vaccination patterns of younger siblings of children with ASD with the vaccination patterns of younger siblings of children without ASD. Design, Setting, and Participants: This investigation was a retrospective matched cohort study. The setting was 6 integrated health care delivery systems across the United States within the Vaccine Safety Datalink. Participants were children born between January 1, 1995, and September 30, 2010, and their younger siblings born between January 1, 1997, and September 30, 2014. The end of follow-up was September 30, 2015. Exposures: Recommended childhood vaccines between ages 1 month and 12 years. Main Outcome and Measure: The proportion of children who received all of their vaccine doses according to ACIP recommendations. Results: The study included 3729 children with ASD (676 [18.1%] female), 592 907 children without ASD, and their respective younger siblings. Among children without ASD, 250 193 (42.2%) were female. For vaccines recommended between ages 4 and 6 years, children with ASD were significantly less likely to be fully vaccinated compared with children without ASD (adjusted rate ratio, 0.87; 95% CI, 0.85-0.88). Within each age category, vaccination rates were significantly lower among younger siblings of children with ASD compared with younger siblings of children without ASD. The adjusted rate ratios varied from 0.86 for siblings younger than 1 year to 0.96 for those 11 to 12 years old. Parents who had a child with ASD were more likely to refuse at least 1 recommended vaccine for that child's younger sibling and to limit the number of vaccines administered during the younger sibling's first year of life. Conclusions and Relevance: Children with ASD and their younger siblings were undervaccinated compared with the general population. The results of this study suggest that children with ASD and their younger siblings are at increased risk of vaccine-preventable diseases.

PMID- 29582074 TI - Enforcing Federal Drug Laws in States Where Medical Marijuana Is Lawful. PMID- 29582076 TI - Ethical Obligations Regarding Short-Term Global Health Clinical Experiences: An American College of Physicians Position Paper. AB - This American College of Physicians position paper aims to inform ethical decision making surrounding participation in short-term global health clinical care experiences. Although the positions are primarily intended for practicing physicians, they may apply to other health care professionals and should inform how institutions, organizations, and others structure short-term global health experiences. The primary goal of short-term global health clinical care experiences is to improve the health and well-being of the individuals and communities where they occur. In addition, potential benefits for participants in global health include increased awareness of global health issues, new medical knowledge, enhanced physical diagnosis skills when practicing in low-technology settings, improved language skills, enhanced cultural sensitivity, a greater capacity for clinical problem solving, and an improved sense of self-satisfaction or professional satisfaction. However, these activities involve several ethical challenges. Addressing these challenges is critical to protecting patient welfare in all geographic locales, promoting fair and equitable care globally, and maintaining trust in the profession. This paper describes 5 core positions that focus on ethics and the clinical care context and provides case scenarios to illustrate them. PMID- 29582075 TI - Using Smartphones and Machine Learning to Quantify Parkinson Disease Severity: The Mobile Parkinson Disease Score. AB - Importance: Current Parkinson disease (PD) measures are subjective, rater dependent, and assessed in clinic. Smartphones can measure PD features, yet no smartphone-derived rating score exists to assess motor symptom severity in real world settings. Objectives: To develop an objective measure of PD severity and test construct validity by evaluating the ability of the measure to capture intraday symptom fluctuations, correlate with current standard PD outcome measures, and respond to dopaminergic therapy. Design, Setting, and Participants: This observational study assessed individuals with PD who remotely completed 5 tasks (voice, finger tapping, gait, balance, and reaction time) on the smartphone application. We used a novel machine-learning-based approach to generate a mobile Parkinson disease score (mPDS) that objectively weighs features derived from each smartphone activity (eg, stride length from the gait activity) and is scaled from 0 to 100 (where higher scores indicate greater severity). Individuals with and without PD additionally completed standard in-person assessments of PD with smartphone assessments during a period of 6 months. Main Outcomes and Measures: Ability of the mPDS to detect intraday symptom fluctuations, the correlation between the mPDS and standard measures, and the ability of the mPDS to respond to dopaminergic medication. Results: The mPDS was derived from 6148 smartphone activity assessments from 129 individuals (mean [SD] age, 58.7 [8.6] years; 56 [43.4%] women). Gait features contributed most to the total mPDS (33.4%). In addition, 23 individuals with PD (mean [SD] age, 64.6 [11.5] years; 11 [48%] women) and 17 without PD (mean [SD] age 54.2 [16.5] years; 12 [71%] women) completed in-clinic assessments. The mPDS detected symptom fluctuations with a mean (SD) intraday change of 13.9 (10.3) points on a scale of 0 to 100. The measure correlated well with the Movement Disorder Society Unified Parkinson Disease's Rating Scale total (r = 0.81; P < .001) and part III only (r = 0.88; P < .001), the Timed Up and Go assessment (r = 0.72; P = .002), and the Hoehn and Yahr stage (r = 0.91; P < .001). The mPDS improved by a mean (SD) of 16.3 (5.6) points in response to dopaminergic therapy. Conclusions and Relevance: Using a novel machine-learning approach, we created and demonstrated construct validity of an objective PD severity score derived from smartphone assessments. This score complements standard PD measures by providing frequent, objective, real-world assessments that could enhance clinical care and evaluation of novel therapeutics. PMID- 29582077 TI - Association of E-Cigarette Use With Smoking Cessation Among Smokers Who Plan to Quit After a Hospitalization: A Prospective Study. AB - Background: Many smokers report using e-cigarettes to help them quit smoking, but whether e-cigarettes aid cessation efforts is uncertain. Objective: To determine whether e-cigarette use after hospital discharge is associated with subsequent tobacco abstinence among smokers who plan to quit and are advised to use evidence based treatment. Design: Secondary data analysis of a randomized controlled trial. (ClinicalTrials.gov: NCT01714323 [parent trial]). Setting: 3 hospitals. Participants: 1357 hospitalized adult cigarette smokers who planned to stop smoking, received tobacco cessation counseling in the hospital, and were randomly assigned at discharge to a tobacco treatment recommendation (control) or free tobacco treatment (intervention). Measurements: Self-reported e-cigarette use (exposure) was assessed 1 and 3 months after discharge; biochemically validated tobacco abstinence (outcome) was assessed 6 months after discharge. Results: Twenty-eight percent of participants used an e-cigarette within 3 months after discharge. In an analysis of 237 propensity score-matched pairs, e-cigarette users were less likely than nonusers to abstain from tobacco use at 6 months (10.1% vs. 26.6%; risk difference, -16.5% [95% CI, -23.3% to -9.6%]). The association between e-cigarette use and quitting varied between intervention patients, who were given easy access to conventional treatment (7.7% vs. 29.8%; risk difference, -22.1% [CI, -32.3% to -11.9%]), and control patients, who received only treatment recommendations (12.0% vs. 24.1%; risk difference, -12.0% [CI, -21.2% to 2.9%]) (P for interaction = 0.143). Limitations: Patients self selected e-cigarette use. Unmeasured confounding is possible in an observational study. Conclusion: During 3 months after hospital discharge, more than a quarter of smokers attempting to quit used e-cigarettes, mostly to aid cessation, but few used them regularly. This pattern of use was associated with less tobacco abstinence at 6 months than among smokers who did not use e-cigarettes. Additional study is needed to determine whether regular use of e-cigarettes aids or hinders smoking cessation. Primary Funding Source: National Heart, Lung, and Blood Institute. PMID- 29582079 TI - 2017 Update on Pediatric Medical Overuse: A Review. AB - Importance: Medical overuse has historically focused on adult health care, but interest in how children are affected by medical overuse is increasing. This review examines important research articles published in 2016 that address pediatric overuse. Observations: A structured search of PubMed and a manual review of the tables of contents of 10 journals identified 169 articles related to pediatric overuse published in 2016, from which 8 were selected based on the quality of methods and potential harm to patients in terms of prevalence and magnitude. Articles were categorized by overtreatment, overmedicalization, and overdiagnosis. Findings included evidence of overtreatment with commercial rehydration solution, antidepressants, and parenteral nutrition; overmedicalization with planned early deliveries, immobilization of ankle injuries, and use of hydrolyzed infant formula; and evidence of overdiagnosis of hypoxemia among children recovering from bronchiolitis. Conclusions and Relevance: The articles were of high quality, with most based on randomized clinical trials. The potential harms associated with pediatric overuse were significant, including increased risk of infection, developmental disability, and suicidality.

PMID- 29582078 TI - Association Between Receptivity to Tobacco Advertising and Progression to Tobacco Use in Youth and Young Adults in the PATH Study. AB - Importance: Cigarette marketing contributes to initiation of cigarette smoking among young people, which has led to restrictions on use of cigarette advertising. However, little is known about other tobacco advertising and progression to tobacco use in youth and young adults. Objective: To investigate whether receptivity to tobacco advertising among youth and young adults is associated with progression (being a susceptible never user or ever user) to use of the product advertised, as well as conventional cigarette smoking. Design, Setting, and Participants: The Population Assessment of Tobacco and Health (PATH) Study at wave 1 (2013-2014) and 1-year follow-up at wave 2 (2014-2015) was conducted in a US population-based sample of never tobacco users aged 12 to 24 years from wave 1 of the PATH Study (N = 10 989). Household interviews using audio computer-assisted self-interviews were conducted. Exposures: Advertising for conventional cigarettes, electronic cigarettes (e-cigarettes), cigars, and smokeless tobacco products at wave 1. Main Outcomes and Measures: Progression to susceptibility or ever tobacco use at 1-year follow-up in wave 2. Results: Of the 10 989 participants (5410 male [weighted percentage, 48.3%]; 5579 female [weighted percentage, 51.7%]), receptivity to any tobacco advertising at wave 1 was high for those aged 12 to 14 years (44.0%; 95% confidence limit [CL], 42.6% 45.4%) but highest for those aged 18 to 21 years (68.7%; 95% CL, 64.9%-72.2%). e Cigarette advertising had the highest receptivity among all age groups. For those aged 12 to 17 years, susceptibility to use a product at wave 1 was significantly associated with product use at wave 2 for conventional cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among committed never users aged 12 to 17 years at wave 1, any receptivity was associated with progression toward use of the product at wave 2 (conventional cigarettes: adjusted odds ratio [AOR], 1.43; 95% CL, 1.23-1.65; e-cigarettes: AOR, 1.62; 95% CL, 1.41-1.85; cigars: AOR, 2.01; 95% CL, 1.62-2.49; and smokeless [males only]: AOR, 1.42; 95% CL, 1.07-1.89) and with use of the product (conventional cigarettes: AOR, 1.54; 95% CL, 1.03-2.32; e cigarettes: AOR, 1.45; 95% CL, 1.19-1.75; cigars: AOR, 2.07; 95% CL, 1.26-3.40). Compared with those not receptive to any product advertising, receptivity to e cigarette advertising, but not to cigarette advertising, was independently associated with those aged 12 to 21 years having used a cigarette at wave 2 (AOR, 1.60; 95% CL, 1.08-2.38). Conclusions and Relevance: Receptivity to tobacco advertising was significantly associated with progression toward use in adolescents. Receptivity was highest for e-cigarette advertising and was associated with trying a cigarette. PMID- 29582082 TI - Use of E-Cigarettes Among Smokers Who Plan to Quit After a Hospitalization.

PMID- 29582086 TI - Applicability of Publicly Reported Hospital Readmission Measures to Unreported Conditions and Other Patient Populations: A Cross-sectional All-Payer Study. AB - Background: Readmission rates after hospitalizations for heart failure (HF), acute myocardial infarction (AMI), and pneumonia among Medicare beneficiaries are used to assess quality and determine reimbursement. Whether these measures reflect readmission rates for other conditions or insurance groups is unknown. Objective: To investigate whether hospital-level 30-day readmission measures for publicly reported conditions (HF, AMI, and pneumonia) among Medicare patients reflect those for Medicare patients hospitalized for unreported conditions or non Medicare patients hospitalized with HF, AMI, or pneumonia. Design: Cross sectional. Setting: Population-based. Participants: Hospitals in the all-payer Nationwide Readmissions Database in 2013 and 2014. Measurements: Hospital-level 30-day all-cause risk-standardized excess readmission ratios (ERRs) were compared for 3 groups of patients: Medicare beneficiaries admitted for HF, AMI, or pneumonia (Medicare reported group); Medicare beneficiaries admitted for other conditions (Medicare unreported group); and non-Medicare beneficiaries admitted for HF, AMI, or pneumonia (non-Medicare group). Results: Within-hospital differences in ERRs varied widely among groups. Medicare reported ratios differed from Medicare unreported ratios by more than 0.1 for 29% of hospitals and from non-Medicare ratios by more than 0.1 for 46% of hospitals. Among hospitals with higher readmission ratios, ERRs for the Medicare reported group tended to overestimate ERRs for the non-Medicare group but underestimate those for the Medicare unreported group. Limitation: Medicare groups and risk adjustment differed slightly from those used by the Centers for Medicare & Medicaid Services. Conclusion: Hospital ERRs, as estimated by Medicare to determine financial penalties, have poor agreement with corresponding measures for populations and conditions not tied to financial penalties. Current publicly reported measures may not be good surrogates for overall hospital quality related to 30-day readmissions. Primary Funding Source: Richard A. and Susan F.

PMID- 29582084 TI - Dual Antiplatelet Therapy in Transient Ischemic Attack and Minor Stroke With Different Infarction Patterns: Subgroup Analysis of the CHANCE Randomized Clinical Trial. AB - Importance: Infarction patterns may serve as important imaging markers to assess the probability of stroke recurrence in transient ischemic attack (TIA) and minor stroke. However, it is unclear whether patients with different infarction patterns benefit differently from dual antiplatelet therapy. Objectives: To investigate whether infarction patterns can stratify the risk of recurrent stroke and whether the efficacy and safety of clopidogrel plus aspirin vs aspirin alone are consistent in different infarction patterns after TIA or minor stroke. Design, Setting, and Participants: In this prespecified imaging substudy of the Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events (CHANCE) randomized clinical trial, a total of 1342 patients with noncardioembolic TIA or minor stroke at 45 sites of CHANCE from October 1, 2009, to July 30, 2012, were included in this substudy. The final analysis was conducted on July 30, 2016, and included 1089 patients with required magnetic resonance imaging sequences. Infarction patterns were grouped into multiple acute infarctions (MAIs), single acute infarction (SAI), and no acute infarction (NAI) according to diffusion-weighted imaging. Main Outcomes and Measures: Primary and secondary efficacy outcomes were stroke recurrence and new clinical vascular event after 3 months, respectively. The safety outcome was moderate to severe bleeding risk after 3 months. Results: Among 1089 patients, the mean (SD) age was 63.1 (10.7) years and 731 patients (65%) were men. Patients with MAIs (hazard ratio [HR], 5.8; 95% CI, 2.2-15.1; P < .001) and SAI (HR, 3.9; 95% CI, 1.5-10.5; P = .007) had higher risk of recurrent stroke than those with NAI after adjustment for potential confounders at 3-month follow-up. Stroke recurrence occurred in 15 (10.1%) and 25 (18.8%) of patients with MAIs administered clopidogrel plus aspirin and placebo plus aspirin, respectively (HR, 0.5; 95% CI, 0.3-0.96; P = .04), 24 (8.9%) and 24 (8.5%) of patients with SAI administered clopidogrel plus aspirin and placebo plus aspirin, respectively (HR, 1.1; 95% CI, 0.6-2.0; P = .71), and 3 (2.6%) and 2 (1.4%) of patients with NAI administered clopidogrel plus aspirin and placebo plus aspirin, respectively (HR, 1.7; 95% CI, 0.3-11.1; P = .56), with P = .04 for treatment * infarction pattern interaction effect. Clopidogrel plus aspirin did not increase moderate to severe bleeding risk. Conclusions and Relevance: Infarction patterns can efficiently stratify the risk of recurrent stroke within 3 months of noncardioembolic TIA or minor ischemic stroke. Patients with MAIs received the most pronounced clinical benefit from dual antiplatelet therapy without increasing the risk of moderate to severe bleeding. However, even if after dual antiplatelet treatment, patients with MAIs still had a risk of stroke recurrence as high as those with SAI. Trial Registration: clinicaltrials.gov Identifier: NCT00979589. PMID- 29582087 TI - Promoting Conditional Use of Communication Skills for Learners With Complex Communication Needs: A Tutorial. AB - Purpose: Conditional use of communication skills refers to the ability of a learner to appropriately generalize and discriminate when, where, and how to communicate based on constant variation and shifts in environmental cues. Method: We describe discrimination and generalization challenges encountered by learners with complex communication needs and ways in which these challenges are fostered through traditional communication intervention programming. We address arrangements in instruction that maximize the probability of learners acquiring the conditional use of new vocabulary and the modest instructional technology implemented when planning for generalization. Results: We propose establishing well-discriminated and generalized use of new vocabulary items through the application of a general case instruction framework to communication intervention programming. Conclusion: We provide intervention methodology, including intervention steps for general case instruction, a plethora of functional examples, and graphic displays to assess and intervene to promote conditional use of communication skills for learners with complex communication needs. PMID- 29582088 TI - Alcohol-Related Nurse Care Management in Primary Care: A Randomized Clinical Trial. AB - Importance: Experts recommend that alcohol use disorders (AUDs) be managed in primary care, but effective approaches are unclear. Objective: To test whether 12 months of alcohol care management, compared with usual care, improved drinking outcomes among patients with or at high risk for AUDs. Design, Setting, and Participants: This randomized clinical trial was conducted at 3 Veterans Affairs (VA) primary care clinics. Between October 11, 2011, and September 30, 2014, the study enrolled 304 outpatients who reported heavy drinking (>=4 drinks per day for women and >=5 drinks per day for men). Interventions: Nurse care managers offered outreach and engagement, repeated brief counseling using motivational interviewing and shared decision making about treatment options, and nurse practitioner-prescribed AUD medications (if desired), supported by an interdisciplinary team (CHOICE intervention). The comparison was usual primary care. Main Outcomes and Measures: Primary outcomes, assessed by blinded telephone interviewers at 12 months, were percentage of heavy drinking days in the prior 28 days measured by timeline follow-back interviews and a binary good drinking outcome, defined as abstinence or drinking below recommended limits in the prior 28 days (according to timeline follow-back interviews) and no alcohol-related symptoms in the past 3 months as measured by the Short Inventory of Problems. Results: Of 304 participants, 275 (90%) were male, 206 (68%) were white, and the mean (SD) age was 51.4 (13.8) years. At baseline, both the CHOICE intervention (n = 150) and usual care (n = 154) groups reported heavy drinking on 61% of days (95% CI, 56%-66%). During the 12-month intervention, 137 of 150 patients in the intervention group (91%) had at least 1 nurse visit, and 77 of 150 (51%) had at least 6 nurse visits. A greater proportion of patients in the intervention group than in the usual care group received alcohol-related care: 42% (95% CI, 35%-49%; 63 of 150 patients) vs 26% (95% CI, 19%-35%; 40 of 154 patients). Alcohol-related care included more AUD medication use: 32% (95% CI, 26%-39%; 48 of 150 patients in the intervention group) vs 8% (95% CI, 5%-13%; 13 of 154 patients in the usual care group). No significant differences in primary outcomes were observed at 12 months between patients in both groups. The percentages of heavy drinking days were 39% (95% CI, 32%-47%) and 35% (95% CI, 28%-42%), and the percentages of patients with a good drinking outcome were 15% (95% CI, 9%-22%; 18 of 124 patients) and 20% (95 % CI, 14%-28%; 27 of 134 patients), in the intervention and usual care groups, respectively (P = .32-.44). Findings at 3 months were similar. Conclusions and Relevance: The CHOICE intervention did not decrease heavy drinking or related problems despite increased engagement in alcohol-related care.

AB - INTRODUCTION AND HYPOTHESIS: Urogenital symptoms are prevalent in older women, but there is little data available on the prevalence, bother, impact and associations with low back pain (LBP), obesity, parity, mental health (MH) and quality of life (QOL) in young women. Our aim was to determine the prevalence, bother and impact of urogenital symptoms and to explore associations with LBP, obesity, parity, MH and QOL in 22 year-old women. METHODS: This was a cross sectional evaluation using data collected from 588 women in the Raine Study, a pregnancy cohort in which participants have been regularly followed up from birth until 22 years. Data was analysed using descriptive statistics, univariate comparisons and linear regression models. RESULTS: Prevalence of urogenital symptoms were stress urinary incontinence (SUI) 6.3%, mixed urinary incontinence (MUI) 11.5%, leakage of drops 5.8%, urge urinary incontinence (UUI) 5.3%, bothersome urinary frequency 41.5%, difficulty emptying 11.8% and urogenital pain 22.9%. Urinary frequency, MUI, difficulty emptying and urogenital pain were most bothersome, whilst difficulty emptying and urogenital pain were associated with greatest impact. Urinary frequency, SUI, leakage of drops, difficulty emptying and urogenital pain were associated with current LBP and LBP ever. Difficulty emptying and urogenital pain were associated with chronic LBP. Urogenital symptoms were not associated with obesity or parity. Women with urogenital symptoms had significantly poorer scores on the Mental Component Score of the Short Form Health Survey (SF)-12 and all aspects of the Depression Anxiety Stress Score. CONCLUSIONS: Urogenital symptoms are prevalent in young women, bothersome for some and are associated with LBP, poorer MH and reduced QOL.

PMID- 29582092 TI - Particulate matter 2.5 damages skin cells by inducing oxidative stress, subcellular organelle dysfunction, and apoptosis. AB - The skin is the largest organ of the human body and the one mostly exposed to outdoor contaminants. To evaluate the biological mechanisms underlying skin damage caused by fine particulate matter (PM2.5), we analyzed the effects of PM2.5 on cultured human keratinocytes and the skin of experimental animals. PM2.5 was applied to human HaCaT keratinocytes at 50 ug/mL for 24 h and to mouse skin at 100 ug/mL for 7 days. The results indicate that PM2.5 induced oxidative stress by generating reactive oxygen species both in vitro and in vivo, which led to DNA damage, lipid peroxidation, and protein carbonylation. As a result, PM2.5 induced endoplasmic reticulum stress, mitochondrial swelling, and autophagy, and caused apoptosis in HaCaT cells and mouse skin tissue. The PM2.5-induced cell damage was attenuated by antioxidant N-acetyl cysteine, confirming that PM2.5 cellular toxicity was due to oxidative stress. These findings contribute to understanding of the pathophysiological mechanisms triggered in the skin by PM2.5, among which oxidative stress may play a major role.

AB - INTRODUCTION: Ataxia-Telangiectasia (A-T) syndrome is an autosomal recessive neurodegenerative disorder characterized by cerebellar ataxia, oculocutaneous telangiectasia, immunodeficiency, chromosome instability, radiosensitivity, and predisposition to malignancy. There is growing evidence that A-T patients suffer from pathologic inflammation that is responsible for many symptoms of this syndrome, including neurodegeneration, autoimmunity, cardiovascular disease, accelerated aging, and insulin resistance. In addition, epidemiological studies have shown A-T heterozygotes, somewhat like deficient patients, are susceptible to ionizing irradiation and have a higher risk of cancers and metabolic disorders. AREA COVERED: This review summarizes clinical and molecular findings of inflammation in A-T syndrome. CONCLUSION: Ataxia-Telangiectasia Mutated (ATM), a master regulator of the DNA damage response is the protein known to be associated with A-T and has a complex nuclear and cytoplasmic role. Loss of ATM function may induce immune deregulation and systemic inflammation. PMID- 29582096 TI - Living with systemic lupus erythematosus in the developing world. AB - Most of our understanding of SLE and its negative impact originates from developed countries. This review aims to collate existing literature on Health Related Quality of Life (HRQoL) in SLE patients living in developing countries to identify the gaps for the focus of future research. A narrative literature review was compiled using selected MeSH terms to search EBSCOHOST for articles published between January 1975 and February 2018 pertaining to HRQoL in SLE patients in developing countries. 31 studies from 11 countries were included for analysis. Only one longitudinal, one randomized controlled trial (RCT), one qualitative study, and two intervention studies were found. High disease activity and organ damage were associated with poor functional ability, mental health and low socio economic status (SES). Poor SES is a recurring theme in developing countries, and worsens all SLE outcomes by reducing access to healthcare, mental, social and emotional support systems. In developing countries, SLE has a globally negative impact on patients' HRQoL, similar to that seen in developed countries. There is an urgent need for more HRQoL studies, and in particular, longitudinal, qualitative and interventional studies in these countries to investigate unmet needs, and to explore novel strategies to improve patient outcomes. PMID- 29582095 TI - Physician-patient communication in rheumatology: a systematic review. AB - The nature of physician-patient interaction can have a significant impact on patient outcomes through information-sharing and disease-specific education that can enhance patients' active involvement in their care. The aim of this systematic review was to examine all the empirical evidence pertaining to aspects of physician-patient communication and its impact on patient outcomes. A systematic search of five electronic databases (MEDLINE, PsycINFO, EMBASE, CINAHL, and Web of Science) was undertaken from earliest record to December 2016. Studies were eligible if they: (1) included adult participants (18 years or over) with a diagnosis of a rheumatic condition; (2) were of quantitative, qualitative or mixed methods design; (4) were surveys, observational and interventional studies; (5) were published in the English language; and (6) reported findings on either various physician-patient communication aspects alone or in combination with physical and psychological outcomes. Searches identified 455 papers. Following full-text retrieval and assessment for eligibility and quality, ten studies were included in the review; six quantitative, one mixed methods, and three qualitative papers. Higher levels of trust in the physician and active patient participation in the medical consultation were linked to lower disease activity, better global health, less organ damage accrual, greater treatment satisfaction with fewer side effects from the medication, more positive beliefs about control over the disease, and about current and future health. Future research could focus on the design and implementation of interventions incorporating communications skills and patient-education training. PMID- 29582097 TI - Native rotational knee kinematics is restored after lateral UKA but not after medial UKA. AB - PURPOSE: The aim of this study was to compare the intraoperative kinematics of medial and lateral unicompartmental knee arthroplasty (UKA) with those of the native knee using a navigation system. METHODS: Six fresh-frozen cadaveric knees were included in the study. Medial UKA was performed in all right knees and lateral UKA was performed in all left knees. All UKA procedures were performed with a computerised navigation system. The tibial internal rotation angle and coronal alignment of the mechanical axis during passive knee flexion were assessed as rotational and varus/valgus kinematics before and after surgery using the navigation system. RESULTS: The rotation angles of the tibia in the early flexion phase of medial UKA were significantly larger than those of native knees (p = 0.008 at minimum knee flexion, p = 0.008 at 0 degrees knee flexion). The rotational kinematics of lateral UKA was similar to those of the native knees throughout knee flexion. There were no significant differences in varus/valgus kinematics between native and UKA knees. CONCLUSION: The rotational kinematics of the native knee was not restored after medial UKA but was preserved after lateral UKA. There were no significant differences in the varus/valgus kinematics after either medial or lateral UKA when compared with those of the native knees. Thus, the geometry of the medial tibial articular surface is a determinant of the ability to restore the rotational kinematics of the native knee. Surgeons and implant designers should be aware that the anatomical medial articular geometry is an important factor in restoration of the native knee kinematics after knee arthroplasty. PMID- 29582098 TI - High reported rate of return to play following bone marrow stimulation for osteochondral lesions of the talus. AB - PURPOSE: The purpose of this study is to systematically review the literature and to evaluate the reported rehabilitation protocols, return to play guidelines and subsequent rates and timing of return to play following bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLT). METHODS: MEDLINE, EMBASE and the Cochrane Library were searched according to the PRISMA guidelines in September 2017. The rate and timing of return to play was assessed. The rehabilitation protocols were recorded, including time to start range of motion, partial weight-bearing and complete weight-bearing. RESULTS: Fifty-seven studies with 3072 ankles were included, with a mean age of 36.9 years (range 23-56.8 years), and a mean follow-up of 46.0 months (range 1.5-141 months). The mean rate of return to play was 86.8% (range 60-100%), and the mean time to return to play was 4.5 months (range 3.5-5.9 months). There was large variability in the reported rehabilitation protocols. Range of motion exercises were most often allowed to begin in the first week (46.2%), and second week postoperatively (23.1%). The most commonly reported time to start partial weight-bearing was the first week (38.8%), and the most frequently reported time of commencing full weight-bearing was 6 weeks (28.8%). Surgeons most often allowed return to play at 4 months (37.5%). CONCLUSIONS: There is a high rate of return following BMS for OLT with 86.8% and the mean time to return to play was 4.5 months. There is also a significant deficiency in reported rehabilitation protocols, and poor quality reporting in return to play criteria. Early weightbearing and early postoperative range of motion exercises appear to be advantageous in accelerated return to sports. LEVEL OF EVIDENCE: Level IV. PMID- 29582099 TI - [Paths to the professional and responsible use of antibiotics]. AB - Germany's position on prescribing antibiotics is among the lower third in Europe. There are some countries that prescribe remarkably fewer antibiotics. In Germany, the number of out-patient antibiotic prescriptions is too high for patients with low-grade infections and non-bacterial infections. Often, broad-spectrum antibiotics are prescribed instead of narrow-spectrum antibiotics. For in patients, perioperative prophylaxis is given for too long.In this article, different ways to reduce antibiotic prescriptions are introduced. Recommendations are given to improve the quality of therapy, implementation of diagnostics and scores, as well as information for physicians and patients.In this regard, an unsystematic literature search was done.To optimise the quality of prescribing, antibiotic checklists should be used. The important initial questions are if there is a bacterial infection and if antibiotic therapy is necessary. To apply diagnostics correctly is essential. Antibiotic use can be shortened or in some cases totally omitted if point-of-care tests (POCTs) are applied correctly. Species identification and resistance testing are essential for quality assurance. S3-guidelines are central for modern evidence-based medicine. Another key factor is good communication within the team and with patients. All measurements, like the application of POCTs, back-up prescribing, and prescribing an antibiotic, have to be communicated in a clear and sensitive way. PMID- 29582100 TI - The impact of time to catheter removal on short-, intermediate- and long-term urinary continence after radical prostatectomy. AB - PURPOSE: To assess the impact of prolonged catheterization time on 1-week (short term), 3-month (intermediate-term) and 1-year (long-term) UC. METHODS: Between 2008 and 2015, 6918 men underwent RP by four high-volume surgeons. Exclusion criteria were baseline urinary incontinence (UI) and radiotherapy prior or within 12 months after RP. For the remaining 4111 patients, data on short-, intermediate and long-term UC were available for 3989, 2490 and 1967 patients, respectively. UC was defined as the use of zero or 1-safety pad/24 h. Time to catheter removal was categorized into <= 7, 8-14 and >= 15 days. To assess the impact of catheterization time on short-, intermediate- and long-term UI, uni- and multivariable logistic regression analyses adjusted for age, BMI, prostate volume, pathological tumor stage, Charlson comorbidity index and nerve-sparing technique were performed. RESULTS: Post-RP UC rates at 1 week for catheterization of <= 7, 8-14 and >= 15 days were 31.2, 27.4 and 18.0%. For the same groups, 3 month and 1-year UC rates were 82.7, 79.2 and 74.1% as well as 90.8, 91.6 and 88.2%, respectively. In multivariate logistic regressions, longer catheterization time was associated with worse short- and intermediate UI (OR 15 days: 2.19 and 1.54; p = <= 0.001 and p = 0.04). This difference dissipated at 1 year after RP (p > 0.05). CONCLUSIONS: While longer catheterization is associated with worse short- and intermediate-term UC, it has no adverse impact on long-term UC. PMID- 29582101 TI - Agromyces mangrovi sp. nov., a novel actinobacterium isolated from the rhizosphere of a mangrove. AB - A novel actinobacterium, designated HIr16-25T, was isolated from the rhizosphere soil of a mangrove growing on Iriomote Island in Japan. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HIr16-25T fell within the cluster of the members of the genus Agromyces and the highest sequence similarity value was observed with Agromyces rhizospherae IFO 16236T (98.6%). Strain HIr16 25T possessed L-2,4-diaminobutyric acid as a diagnostic diamino acid of the peptidoglycan, and MK-12 and MK-11 as the predominant menaquinones. The major fatty acids were identified as iso-C16:0, anteiso-C15:0 and anteiso-C17:0 and the principal polar lipids were phosphatidylglycerol and one glycolipid. These chemotaxonomic features matched well those described for the members of the genus Agromyces. Meanwhile, the result of DNA-DNA hybridization and the presence of differential phenotypic characteristics between strain HIr16-25T and the type strain of A. rhizospherae indicated that strain HIr16-25T be classified as a novel species of the genus Agromyces. Therefore, we propose strain HIr16-25T to represent a novel species of the genus Agromyces, with the name Agromyces mangrovi sp. nov. The type strain is HIr16-25T (= NBRC 112812T = TBRC 7760T).

PMID- 29582104 TI - Practices of shake-flask culture and advances in monitoring CO2 and O2. AB - About 85 years have passed since the shaking culture was devised. Since then, various monitoring devices have been developed to measure culture parameters. O2 consumed and CO2 produced by the respiration of cells in shaking cultures are of paramount importance due to their presence in both the culture broth and headspace of shake flask. Monitoring in situ conditions during shake-flask culture is useful for analysing the behaviour of O2 and CO2, which interact according to Henry's law, and is more convenient than conventional sampling that requires interruption of shaking. In situ monitoring devices for shake-flask cultures are classified as direct or the recently developed bypass type. It is important to understand the characteristics of each type along with their unintended effect on shake-flask cultures, in order to improve the existing devices and culture conditions. Technical developments in the bypass monitoring devices are strongly desired in the future. It is also necessary to understand the mechanism underlying conventional shake-flask culture. The existing shaking culture methodology can be expanded into next-generation shake-flask cultures constituting a novel culture environment through a judicious selection of monitoring devices depending on the intended purpose of shake-flask culture. Construction and sharing the databases compatible with the various types of the monitoring devices and measurement instruments adapted for shaking culture can provide a valuable resource for broadening the application of cells with shake flask culture. PMID- 29582105 TI - Microbial Decomposer Dynamics: Diversity and Functionality Investigated through a Transplantation Experiment in Boreal Forests. AB - Litter decomposition is the main source of mineral nitrogen (N) in terrestrial ecosystem and a key step in carbon (C) cycle. Microbial community is the main decomposer, and its specialization on specific litter is considered at the basis of higher decomposition rate in its natural environment than in other forests. However, there are contrasting evidences on how the microbial community responds to a new litter input and if the mass loss is higher in natural environment. We selected leaf litter from three different plant species across three sites of different altitudinal ranges: oak (Quercus petraea (Matt.) Liebl., 530 m a.s.l), beech (Fagus sylvatica L., 1000 m a.s.l.), rhododendron (Rhododendron ferrugineum L., 1530 m a.s.l.). A complete transplantation experiment was set up within the native site and the other two altitudinal sites. Microbial community structure was analyzed via amplified ribosomal intergenic spacer analysis (ARISA) fingerprinting. Functionality was investigated by potential enzyme activities. Chemical composition of litter was recorded. Mass loss showed no faster decomposition rate on native site. Similarly, no influence of site was found on microbial structure, while there was a strong temporal variation. Potential enzymatic activities were not affected by the same temporal pattern with a general increase of activities during autumn. Our results suggested that no specialization in microbial community is present due to the lack of influence of the site in structure and in the mass loss dynamics. Finally, different temporal patterns in microbial community and potential enzymatic activities suggest the presence of functional redundancy within decomposers. PMID- 29582106 TI - Trends and variations in the prescribing of secondary preventative cardiovascular therapies for non-ST elevation myocardial infarction (NSTEMI) in Malaysia. AB - PURPOSE: Information is lacking on prescribing of preventative cardiovascular pharmacotherapies for patients with non-ST elevation myocardial infarction (NSTEMI) in the Asian region. This study examined the prescribing rate of these pharmacotherapies, comparing NSTEMI to STEMI, and variations across demographics and clinical factors within the NSTEMI group in the multi-ethnic Malaysian population. METHODS: This is a retrospective analysis of the Malaysian National Cardiovascular Disease Database-Acute Coronary Syndrome registry from year 2006 to 2013 (n = 30,873). On-discharge pharmacotherapies examined were aspirin, ADP antagonists, statins, ACE-inhibitors, angiotensin-II-receptor blockers, and beta blockers. Multivariate logistic regression was used to calculate adjusted odds ratio of receiving individual pharmacotherapies according to patients' characteristics in NSTEMI patients (n = 11,390). RESULTS: Prescribing rates for cardiovascular pharmacotherapies had significantly increased especially for ADP antagonists (76%) in NSTEMI patients. More than 85% were prescribed statins and antiplatelets but rates remained significantly lower compared to STEMI. Women and those over 65 years old were less likely to be prescribed these pharmacotherapies compared to men and younger NSTEMI patients. Chinese and Indians were more likely to receive selected pharmacotherapies compared to Malays (main ethnicity). Geographical variations were observed; East Malaysian (Malaysian Borneo) patients were less likely to receive these compared to Western region of Malaysian Peninsular. Underprescribing in patients with risk factors such as diabetes were observed with other co-morbidities influencing prescribing selectively. CONCLUSION: This study uncovers demographic and clinical variations in cardiovascular pharmacotherapies prescribing for NSTEMI. Concerted efforts by policy makers, specialty societies, and physicians are required focusing on elderly, women, Malays, East Malaysians, and high-risk patients. PMID- 29582107 TI - Effects of stimulus pair orientation and hand switching on reaction time estimates of interhemispheric transfer. AB - Two behavioral estimates of interhemispheric transfer time, the crossed-uncrossed difference (CUD) and the unilateral field advantage (UFA), are thought to, respectively, index transfer of premotor and visual information across the corpus callosum in neurotypical participants. However, no attempt to manipulate visual and motor contingencies in a set of tasks while measuring the CUD and the UFA has yet been reported. In two go/no-go comparison experiments, stimulus pair orientations were manipulated. The hand of response changed after each correct response in the second, but not the first experiment. No correlation was found between the CUD and the UFA, supporting the hypothesis that these two measures index different types of information transfer across hemispheres. An effect of manipulation of stimulus pair orientation on UFAs was attributed to the homotopy of callosal fibers transferring visual information, while an effect of hand switching on CUDs was attributed mostly to spatial compatibility. PMID- 29582108 TI - Underestimation of large distances in active and passive locomotion. AB - Our ability to estimate distances, be it verbally or by locomotion, is exquisite at close range (action space). At distances above 100 m (vista space), verbal estimates continue to be quite accurate, whereas locomotor estimates have been found to be grossly underestimated. Until now, however, the latter have been performed on a treadmill, which might not translate to real-world walking. We investigated if the motor underestimation found on the treadmill holds up in a natural environment. Observers viewed pictures of objects at distances between 10 and 245 m and were asked to reproduce these distances in a blindfolded walking task (using passive movement or an active production method). Active and passive locomotor judgments underestimated far distances above 100 m. We conclude that underestimation of large distances does not depend on the medium (treadmill vs. real-world) but rather on the sensory modality and effort involved in the task.

PMID- 29582111 TI - Clinical Utility of Diffusion-Weighted Imaging in Spinal Infections. AB - PURPOSE: Both laboratory markers and radiographic findings in the setting of spinal infections can be nonspecific in determining the presence or absence of active infection, and can lag behind both clinical symptoms and antibiotic response. Magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) has been shown to be helpful in evaluating brain abscesses but has not been commonly used in evaluating spinal infections. We aimed to correlate findings on DWI of the spine to results of microbiological sampling in patients with suspected spinal infections. METHODS: Patients who underwent MRI with DWI for suspicion of spinal infections and microbiological sampling from 2002 to 2010 were identified and reviewed retrospectively in this institutional review board approved study. In addition to DWI, scans included sagittal and axial T1, fast spin echo (FSE) T2, and post-gadolinium T1 with fat saturation. Regions of interest were drawn on apparent diffusion coefficient (ADC) maps in the area of suspected infections, and ADC values were correlated with microbiological sampling. RESULTS: Of 38 patients with suspected spinal infections, 29 (76%) had positive microbiological sampling, and 9 (24%) had negative results. The median ADC value was 740 * 10-6 mm2/s for patients with positive microbiological sampling and 1980 * 10-6 mm2/s for patients with negative microbiological sampling (p < 0.001). Using an ADC value of 1250 * 10-6 mm2/s or less as the cut off value for a positive result for spinal infection, sensitivity was 66%, specificity was 88%, positive predictive value was 95%, negative predictive value was 41% and accuracy was 70%. CONCLUSION: In patients with suspected spine infection, ADC values on DWI are significantly reduced in those patients with positive microbiological sampling compared to patients with negative microbiological sampling. The DWI of the spine correlates well with the presence or absence of spinal infection and may complement conventional magnetic resonance imaging (MRI). PMID- 29582113 TI - Mapping of new quantitative trait loci for sudden death syndrome and soybean cyst nematode resistance in two soybean populations. AB - KEY MESSAGE: Novel QTL conferring resistance to both the SDS and SCN was detected in two RIL populations. Dual resistant RILs could be used in breeding programs for developing resistant soybean cultivars. Soybean cultivars, susceptible to the fungus Fusarium virguliforme, which causes sudden death syndrome (SDS), and to the soybean cyst nematode (SCN) (Heterodera glycines), suffer yield losses valued over a billion dollars annually. Both pathogens may occur in the same production fields. Planting of cultivars genetically resistant to both pathogens is considered one of the most effective means to control the two pathogens. The objective of the study was to map quantitative trait loci (QTL) underlying SDS and SCN resistances. Two recombinant inbred line (RIL) populations were developed by crossing 'A95-684043', a high-yielding maturity group (MG) II line resistant to SCN, with 'LS94-3207' and 'LS98-0582' of MG IV, resistant to both F. virguliforme and SCN. Two hundred F7 derived recombinant inbred lines from each population AX19286 (A95-684043 * LS94-3207) and AX19287 (A95-684043 * LS98-0582) were screened for resistance to each pathogen under greenhouse conditions. Five hundred and eighty and 371 SNP markers were used for mapping resistance QTL in each population. In AX19286, one novel SCN resistance QTL was mapped to chromosome 8. In AX19287, one novel SDS resistance QTL was mapped to chromosome 17 and one novel SCN resistance QTL was mapped to chromosome 11. Previously identified additional SDS and SCN resistance QTL were also detected in the study. Lines possessing superior resistance to both pathogens were also identified and could be used as germplasm sources for breeding SDS- and SCN-resistant soybean cultivars. PMID- 29582112 TI - Role of neurogenic inflammation in local communication in the visceral mucosa. AB - Intense research has focused on the involvement of the nervous system in regard to cellular mechanisms underlying neurogenic inflammation in the pelvic viscera. Evidence supports the neural release of inflammatory factors, trophic factors, and neuropeptides in the initiation of inflammation. However, more recently, non neuronal cells including epithelia, endothelial, mast cells, and paraneurons are likely important participants in nervous system functions. For example, the urinary bladder urothelial cells are emerging as key elements in the detection and transmission of both physiological and nociceptive stimuli in the lower urinary tract. There is mounting evidence that these cells are involved in sensory mechanisms and can release mediators. Further, localization of afferent nerves next to the urothelium suggests these cells may be targets for transmitters released from bladder nerves and that chemicals released by urothelial cells may alter afferent excitability. Modifications of this type of communication in a number of pathological conditions can result in altered release of epithelial-derived mediators, which can activate local sensory nerves. Taken together, these and other findings highlighted in this review suggest that neurogenic inflammation involves complex anatomical and physiological interactions among a number of cell types in the bladder wall. The specific factors and pathways that mediate inflammatory responses in both acute and chronic conditions are not well understood and need to be further examined. Elucidation of mechanisms impacting on these pathways may provide insights into the pathology of various types of disorders involving the pelvic viscera. PMID- 29582115 TI - Osteonecrosis in sickle cell disease patients from Bahia, Brazil: a cross sectional study. AB - PURPOSE: The aim of this study was to describe the clinical features of osteonecrosis (ON) in sickle cell disease (SCD) patients in Bahia, a Northeast state with the highest prevalence of the disease in Brazil. METHODS: Between 2006 and 2017, 283 cases of osteonecrosis in SCD patients were enrolled to analyse the age at diagnosis, genotype, gender, pain, distribution of the lesions and disease staging. MRI and radiograph were obtained at the participation. RESULTS: Of the 283 SCD cases, 120 (42.4%) were haemoglobin SS genotype while 163 (57.6%) were SC genotype. Two hundred and forty-six cases were bilateral and 37 were unilateral, with an average age at diagnosis of 33.7 (range 10-67) years. The most frequent identified ON site not only was the hip (74.6%), but also affected shoulder, knee and ankle. Most cases presented at early stage I (172, 60.8%) disease. No significant differences on the features of osteonecrosis were identified between haemoglobin SS and haemoglobin SC cases. CONCLUSIONS: Given the relatively high prevalence of bilateral osteonecrosis at early stages, painful symptoms and rather late age at diagnosis, SCD patients should have radiological examination of their joints more often in order to prevent severe functional disability and increase patient's life quality. PMID- 29582114 TI - Vertical shear pelvic injury: evaluation, management, and fixation strategies. AB - Vertical shear pelvic ring fractures are rare and account for less than 1% of all fractures. Unlike severely displaced antero-posterior compression and lateral compression pelvic fractures, patients' mortality is lower. Nevertheless, patients must be managed acutely using well-defined ATLS protocols and institution-specific protocols for haemodynamically unstable pelvic ring fractures. The definitive treatment of vertical shear pelvic fractures is however more controversial with a paucity of literature to recommend the ideal reduction and fixation strategy. While the majority of injuries can be reduced and fixed in a closed manner, orthopaedic traumatologists should be familiar with the contraindications to those techniques as well as options such as tension band plating and lumbo pelvic fixation. Our paper reviews the acute management, associated injuries and definitive reduction and fixation strategies of vertical shear pelvic fractures. In addition, we propose a treatment algorithm for the selection of the most appropriate fixation technique. PMID- 29582116 TI - Computer-assisted surgery prevents complications during peri-acetabular osteotomy. AB - PURPOSE: The aim of study is to evaluate the accuracy of a navigation system during curved peri-acetabular osteotomy (CPO). METHODS: Forty-seven patients (53 hips) with hip dysplasia were enrolled and underwent CPO with or without navigation during surgery. Clinical and radiographical evaluations were performed and compared between the navigation group and non-navigation group, post operatively. RESULTS: The clinical outcomes were not significantly different between the navigation and non-navigation groups. Furthermore, post-operative reorientation of the acetabular fragment was similar between the navigation and non-navigation groups. However, the discrepancy between the pre-operative planning line and post-operative osteotomy line was significantly improved in the navigation group compared with that in the non-navigation group (p < 0.05). Further, the complication rate was significantly improved in the navigation group (p < 0.001). CONCLUSION: The accuracy of the osteotomy's position was significantly improved by using the navigation. Therefore, the use of navigation during peri-acetabular osteotomy can avoid complications. PMID- 29582117 TI - Double calcaneal osteotomy with minimally invasive surgery for the treatment of severe flexible flatfeet. AB - BACKGROUND: Severe flexible flatfoot deformity in children and adolescents is a complex problem. Calcaneal lengthening remains the gold standard for surgical correction at this institution. However, in a minority of patients, inadequate correction of valgus is noted at surgery and a further calcaneal shift osteotomy is done. METHODS: We have conducted a retrospective review of ten patients who received 15 combined minimally invasive calcaneal shift and calcaneal lengthening osteotomies, which were all performed by the senior author. All patients had failed conservative treatment. We describe our technique for double calcaneal osteotomy combining minimally invasive surgery (MIS) for the medial calcaneal shift with traditional open calcaneal lengthening osteotomy for treating children and adolescents with severe flexible flatfoot deformity. RESULTS: The average shift achieved was 8.07 mm. The average improvement in Meary's angle was 14.99 degrees . All of them had radiological and clinical union at 12 weeks. None of the patients developed sural nerve injury, wound breakdown, or infection of the MIS incision. CONCLUSION: In double calcaneal osteotomies, the MIS calcaneal medial shift technique can be used safely with potentially lower risks of wound complications and sufficient medial shift, compared to conventional open extensive surgery. IMPLICATIONS: MIS calcaneal shift osteotomy has an advantage over open conventional open technique in cases where the skin is under tension like in combined calcaneal lengthening osteotomy. With experience, the procedure can be faster than an open procedure. PMID- 29582118 TI - Reverse total shoulder arthroplasty using helical blade to optimize glenoid fixation and bone preservation: preliminary results in thirty five patients with minimum two year follow-up. AB - PURPOSE: Glenoid loosening is a common cause of reverse total shoulder arthroplasty (RTSA) failure, and grafting of the glenoid is often required for revision due to bone loss due to the central peg in most glenoid baseplates. Helical blades have been used in the hip to optimize bone fixation in proximal femoral fracture. This study presents the initial results of specifically designed helical blade in the shoulder to optimize glenoid bone fixation and preservation as part of RTSA. METHODS: Thirty-five patients underwent RTSA with glenoid helical blade fixation. An uncemented glenoid baseplate was used with a central helical blade partially coated with hydroxyapatite and two or three screws. Outcome analysis was performed pre-operatively and at two years. RESULTS: All patients were satisfied with the results and significant improvement was observed in functional outcome scores between baseline and final follow-up. There was a single intra-operative undisplaced glenoid fracture which did not compromise the baseplate fixation. There was no radiographic evidence of loosening or radiolucencies around the helical blade. CONCLUSIONS: The helical blade provides a satisfactory primary fixation. Because of its length (21 mm), care should be taken in cases of pre-existing bone loss or sclerotic bone to avoid glenoid fracture or anterior cortical perforation. Helical blade has the potential to facilitate glenoid implant revision by preserving the glenoid bone stock. PMID- 29582119 TI - Molecularly imprinted polymers fabricated via Pickering emulsions stabilized solely by food-grade casein colloidal nanoparticles for selective protein recognition. AB - Novel molecularly imprinted polymers (MIPs) based on denatured casein nanoparticle (DCP)-stabilized Pickering emulsions were developed for the first time. Casein, a phosphoprotein, is the main protein in milk. In this work, DCPs were solely used as Pickering-type interfacial emulsifiers for fabrication of MIPs for the selective recognition of proteins for the first time. DCPs were prepared by acidification and heat denaturation (at 80 degrees C) of casein. Their dispersions have satisfactory colloidal stability over a wide pH range. The DCPs acted as natural, food-grade, and edible interfacial emulsifiers, and adsorbed at the oil-water interface to form Pickering emulsions. After the polymerization of monomers, the template protein was removed by elution. During the elution, the interfacial DCPs were also removed, allowing more imprinted cavities to become exposed. The interfacial imprinting technology causes nearly all the imprinted sites to locate on the surface of the polymeric material. Therefore, the MIPs obtained exhibit fast rebinding and excellent specific recognition ability toward the analytes. Overall, this work provides a promising method for designing and fabricating natural-protein-based structured emulsions to prepare MIPs and thus offers new insight into protein separation and purification. Graphical Abstract Pickering emulsions stabilized by denatured casein particles. PMID- 29582121 TI - Naked eye detection of infertility based on sperm protamine-induced aggregation of heparin gold nanoparticles. AB - The development of an easy to use, one-pot, environmentally friendly, non invasive and label-free colorimetric probe for the determination of semen protamines, the biochemical marker of male fertility, using heparin gold nanoparticles (HAuNPs) is presented. The affinity of HAuNPs for protamines was due to the electrostatic interactions between polycationic protamine and polyanionic heparin. The binding of HAuNPs to protamine was characterized by variation in the plasmon absorption spectra followed by a visibly observable colour change of the solution from red to blue. We observed a red shift in the plasmon peak and the method exhibited linearity in the range of 10-70 ng/mL with a detection limit of 5 ng/mL, which is much lower than that reported for colorimetric sensors of protamine. The colour change and the variation in the absorbance of HAuNPs were highly specific for protamines in the presence of different interfering compounds and the method was successfully applied for determining protamine in real samples of semen and serum. Rather than a quantitative estimation, it seems that the method provides a quick screening between a large array of positive and negative samples and, moreover, it maintains the privacy of the user. The method appears to be simple and would be very useful in third-world countries where high-tech diagnostic aids are inaccessible to the majority of the population. Graphical Abstract Heparin gold nanoparticles aided visual detection of infertility. PMID- 29582122 TI - Comprehensive 2D gas chromatography-time-of-flight mass spectrometry with 2D retention indices for analysis of volatile compounds in frankincense (Boswellia papyrifera). AB - Frankincense gum resin secreted from Boswellia papyrifera was analysed by comprehensive 2D gas chromatography hyphenated with accurate mass time-of-flight mass spectrometry (GC*GC-accTOFMS). Direct multiple injection experiments with stepwise isothermal temperature programming were then performed to construct isovolatility curves for reference alkane series in GC*GC. This provides access to calculation of second dimensional retention indices (2I). More than 500 peaks were detected and 220 compounds mainly comprising monoterpenes, sesquiterpenes, diterpenes and oxygenated forms of these compounds were identified according to their 1I, 2I and accurate mass data. The study demonstrates the capability of GC*GC-accTOFMS with retention data on two separate column phases, as an approach for improved component identification. A greater number of identified and/or tentatively identified terpenoids in this traditional Chinese medicine allow for a more comprehensive coverage of the volatile composition of frankincense. PMID- 29582120 TI - Consumer-friendly food allergen detection: moving towards smartphone-based immunoassays. AB - In this critical review, we provide a comprehensive overview of immunochemical food allergen assays and detectors in the context of their user-friendliness, through their connection to smartphones. Smartphone-based analysis is centered around citizen science, putting analysis into the hands of the consumer. Food allergies represent a significant worldwide health concern and consumers should be able to analyze their foods, whenever and wherever they are, for allergen presence. Owing to the need for a scientific background, traditional laboratory based detection methods are generally unsuitable for the consumer. Therefore, it is important to develop simple, safe, and rapid assays that can be linked with smartphones as detectors to improve user accessibility. Smartphones make excellent detection systems because of their cameras, embedded flash functions, portability, connectivity, and affordability. Therefore, this review has summarized traditional laboratory-based methods for food allergen detection such as enzyme-linked-immunosorbent assay, flow cytometry, and surface plasmon resonance, and the potential to modernize these methods by interfacing them with a smartphone readout system, based on the aforementioned smartphone characteristics. This is the first review focusing on smartphone-based food allergen detection methods designed with the intention of being consumer friendly. Graphical abstract A smartphone-based food allergen detection system in three easy steps (1) sample preparation, (2) allergen detection on a smartphone using antibodies, which then transmits the data wirelessly, (3) analytical results sent straight to smartphone. PMID- 29582123 TI - Increased incidence of abnormally located ovary in patients with Mayer-Rokitansky Kuster-Hauser syndrome: a retrospective analysis with magnetic resonance imaging. AB - PURPOSE: To explore the incidence of abnormally located ovary in patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome as compared to a control group with magnetic resonance imaging. METHODS: Pelvic MR images of 83 MRKH patients and 60 age-matched normal females were retrospectively reviewed by two experienced gynecological radiologists in consensus. Characteristics including location of ovary, ovarian volume, and follicle counts were assessed. The incidence of abnormally located ovary was compared between MRKH patients and controls. The ovarian size and follicle counts were compared among three groups: abnormally located ovaries in MRKH patients, eutopic ovaries in MRKH patients, and normal controls. RESULTS: In total, 166 ovaries of 83 MRKH patients and 120 ovaries of 60 control females were evaluated. Thirty-seven ovaries of 23 MRKH patients (28%, 23/83) were abnormally located, whereas 3 ovaries of three control females (5%, 3/60) were located in abnormal positions (P < 0.001). The mean volume was 9.2 +/- 6.3 mL of the abnormally located ovaries in MRKH patients, 7.8 +/- 4.0 mL of the eutopic ovaries in MRKH patients, and 8.9 +/- 4.8 mL in control females (P > 0.05). No obvious differences were observed with regard to follicle counts among the three groups. CONCLUSION: Incidence of abnormally located ovary was significantly increased in patients with MRKH syndrome. Such knowledge is important for infertility treatment, evaluation of pelvic pain, and surgical planning for MRKH patients. PMID- 29582124 TI - Relative diagnostic utility of radiologist-recommended abdominal ultrasound following emergency department abdominal and pelvic computed tomography. AB - PURPOSE: To retrospectively assess the relative diagnostic utility of radiologist recommended ultrasound (US) following emergency department (ED) abdominal and pelvic computed tomography (CT) in patients with non-traumatic abdominal and/or pelvic pain. METHODS: Blinded to clinical outcomes, two radiology residents and an attending radiologist reviewed radiology reports and relevant medical records for all adult patients from EDs at two academic medical centers from one institution over a 3-year time period, who underwent abdominal/pelvic US within 72 h of an initial IV contrast-enhanced abdominal and pelvic CT for non-traumatic abdominal and/or pelvic pain. Incremental diagnostic utility of subsequent US was deemed present when (1) US findings were discordant with those at CT, or (2) findings were concordant, but US yielded additional relevant diagnostic information. Diagnostic utility was stratified by whether examinations were radiologist-recommended or independently ordered by treating physicians. RESULTS: 319 encounters satisfied the inclusion criteria, including 194 female patients (18-98 years of age, mean of 59.8 years) and 125 male patients (20-90 years of age, mean of 63.2 years). 7 (2.2%) subsequent US examinations were discordant with the initial CT, 100 (31.3%) were concordant but provided relevant additional information, and 212 (66.5%) were concordant without providing additional information, for an overall diagnostic utility of 33.5%. Of subsequent radiologist-recommended US examinations, 70.0% (63/90) yielded incremental diagnostic utility vs. 19.2% (44/229) ordered independently by treating physicians (OR 3.65; 95% CI 2.31-5.75). For those encounters in which US provided incremental diagnostic utility, the most commonly assessed anatomical areas were the biliary system and the female adnexal region. CONCLUSION: In ED patients with non-traumatic abdominal and/or pelvic pain undergoing abdominal and pelvic CT, follow-up US examinations recommended by radiologists are more likely to provide incremental diagnostic utility than those independently ordered by their treating physicians. In order to optimize the value of advanced imaging, radiologists should assume greater roles in team-based utilization management. PMID- 29582125 TI - Does the Site of the Primary Affect Outcomes When Ablating Colorectal Liver Metastases with Radiofrequency Ablation? AB - PURPOSE: To determine whether primary tumor side was a predictor of radiofrequency ablation (RFA) outcome in colorectal liver metastases (CRLM). MATERIALS AND METHODS: The institutional review board approved this retrospective study. Written informed consent was obtained from all patients. From January 2007 to December 2013, 102 patients underwent RFA of metachronous CRLM were enrolled in this study with propensity score matching method. Recurrence rate (RR) and overall survival (OS) were analyzed between two patients cohorts with primary left-side colorectal cancer (LSCRC) or primary right-side colon cancer (RSCC). RESULTS: The total RR was 59.8% in all patients. Patients in LSCRC cohort had lower RR and non-local recurrence (NLR) rate than those in RSCC patients' cohort (49.0 vs 70.6%, p = 0.026 and 21.6 vs 41.2%, p = 0.033). Five-year OS was 14 and 30% for RSCC and LSCRC, respectively. There was a significant difference between two cohorts in median OS (29.4 vs 40.3 months for RSCC and LSCRC, respectively, p = 0.042). Univariate analysis showed that primary tumor side, the number of liver metastases, tumor size, carcinoembryonic antigen level, differentiation, TNM stage, active chemotherapy and RFA boundary were significant in predicting OS. When these variables were subsequently entered in a multivariate model, RSCC (p < 0.001; hazard ratio [HR], 6.2) and tumor size (> 3 cm) (p = 0.006; HR, 3.9) were significant. CONCLUSION: LSCRC and tumor size (<= 3 cm) are independent predictors of RFA in CRLM and yield the better oncologic outcomes. PMID- 29582126 TI - Endovascular Treatment of Haemodialysis Arteriovenous Fistula with Drug-Coated Balloon Angioplasty: A Single-Centre Study. AB - PURPOSE: To evaluate the effect of percutaneous transluminal angioplasty (PTA) on haemodialysis fistulas utilising drug-coated balloons with plain balloon vessel preparation (DCB). MATERIALS AND METHODS: In the study group, 31 patients (16 men; mean age 62.8 +/- 17.2 years) with failing arteriovenous fistulas were treated, with DCB, and compared with a control group (31 patients; 15 men; mean age 67.0 +/- 8.44 years), in which only plain balloon PTA was performed. All stenoses were dilated with regular PTA balloons. After achieving haemodynamic success (< 30% residual stenosis), drug-coated balloons were used for drug administration in the study group. The follow-up intervals were 6, 12 and 24 months. Target lesion primary patency, primary assisted patency and secondary patency were compared. The statistical significance was set at 0.05. RESULTS: Target lesion primary patency was compared in both groups and was significantly higher in the study group (DCB) at 6 months (90.3 vs. 61.3%; p = 0.016), 12 months (77.4 vs. 29%; p = 0.0004) as well as 24 months (45.2 vs. 16.1%; p = 0.026). Kaplan-Meier survival curves also showed a significant difference for target lesion primary patency (534.2 vs. 315.7 days; p = 0.0004). There were no significant differences in target lesion primary assisted patency and in secondary patency. However, only 38.7% of patients in the study group were treated twice or more versus 80.6% in the control group (p = 0.002). CONCLUSION: DCB increases target lesion primary patency during the first 24 months and decreases the rate of reinterventions. PMID- 29582127 TI - Prostatic Artery Embolization (PAE) for Benign Prostatic Hyperplasia (BPH) with Haematuria in the Absence of an Upper Urinary Tract Pathology. AB - PURPOSE: To assess the effectiveness of prostate artery embolization (PAE) in the control of haematuria and in patients with benign prostatic hyperplasia (BPH) and normal upper urinary tracts. SUBJECTS/PATIENTS: Twelve consecutive patients with haematuria were included in the prospective study. All patients had prior imaging and cystoscopy to exclude other causes of haematuria. Patients prostate arteries were embolized with particles (200-500 MUm), and they were followed up at 3, 12 and 18 months following the procedure. QOL questionnaires, IPSS, IIEF and clinical review were all employed to assess the success of the treatment. To allow useful comparison, patients were age- and prostate volume-matched and compared to patients treated with PAE for BPH without haematuria. RESULTS: All 12/12 cases were technically successful with bilateral PAE being performed. All cases of haematuria resolved by the 3-month follow-up (100%). There was one case of recurrence during the 12-month follow-up (overall clinical success at 18 months 92%). This was due to over anticoagulation and ceased once corrected. There was a reduction in lower urinary tract symptoms noted by improvements in QOL indices, IPSS and IIEF. There was continued success even if the patient was subsequently anticoagulated. There was no associated sexual dysfunction. There was more prostatic arterial branching and volume of embolic required to achieve stasis in BPH and haematuria than in BPH alone (p < 0.05). CONCLUSION: PAE is a very useful technique for controlling the quite debilitating condition of haematuria in patients with visible haematuria of prostatic origin. Controlling haematuria and BPH allows a significant improvement in QOL. PMID- 29582128 TI - Safety and Efficacy of Percutaneous Thermal Ablation of Juxta-Cardiac Hepatic Tumours. AB - INTRODUCTION: To evaluate the safety and efficacy of percutaneous thermal ablation of liver tumours in a juxta-cardiac (JC) location. MATERIALS AND METHODS: From January 2010 to December 2014, out of 274 cases of hepatic ablation, 33 consecutive patients who received thermal ablation (radiofrequency or microwave) to left hepatic lobe tumours were included in this study. Patients were divided into two groups: JC or non-juxta-cardiac (NJC) (tumour margin <= 10 mm or > 10 mm from the cardiac border, respectively). Imaging follow-up was performed at 6-week and 3-monthly intervals. Technical success, 30-day complications and local tumour control/recurrence were recorded. Statistical analysis was performed with t test and Fisher's test. Univariate and multivariate survival analyses were performed using Cox regression. RESULTS: Patients comprised of 23 men and 10 women (mean age 67.0 years). Mean tumour size was 2.2 +/- 0.9 cm (28 hepatocellular carcinoma and 5 metastases). Mean follow-up time was 21.2 months (range 2-72 months). There were no differences between the JC and NJC groups in the rates of complete ablation (86.7 vs 83.3% P = 1.0), tumour recurrence (20.0 vs 22.2%, P = 0.95) or complication rates (6.7 vs 11.1% P = 1.0). Metastatic lesions were associated with a higher rate of recurrent disease (hazard ratio 3.86, 95% CI 1.0-14.8%, P = 0.05). DISCUSSION: Percutaneous thermal ablation of JC tumours has similar rates of local tumour control and safety profile when compared to tumours in a NJC location. Tumours in a JC location should not be considered a contraindication for thermal ablation. PMID- 29582129 TI - Evaluating the Feasibility of Isolated Pancreatic Perfusion for Chemotherapy Using Computed Tomography: An Experimental Study in Pig Models. AB - PURPOSE: Percutaneous isolated pancreatic perfusion (PIPP) is performed along with interventional radiology techniques to obtain high drug concentration by occluding the arterial inlet and venous outlet of the pancreas. The experimental study aimed to evaluate the contrast distribution in PIPP under different flow rates with or without anterior mesenteric artery (AMA) occlusion. MATERIALS AND METHODS: This study was approved by a local animal experiment ethics committee. Nine pigs were divided into Groups 1, 2, and 3, by infusion rates of 12, 24, and 36 mL/min. Groups 4 and 5 (3 pigs each) and Group 6 (2 pigs) underwent PIPP at the same respective infusion rates with and without AMA occlusion. Computed tomography (CT) arteriography was performed during PIPP with nonionic contrast media. The enhanced volume was calculated by adding the enhanced area in each slice using 1.25-mm axial images. The percent enhanced volume to the whole pancreas (%eV) was used to simulate drug distribution; the result was compared among groups. RESULTS: Without AMA occlusion, a larger %eV was obtained with high infusion rates (P = 0.039). The median %eV in Groups 1, 2, and 3 were 57.7, 74.2, and 90.5%, respectively. With AMA occlusion, CT demonstrated duodenal enhancement at an infusion rate of 36 mL/min, and the median %eV in Groups 4, 5, and 6 were 92.8, 95.4, and 98.5%, respectively. A significantly larger %eV was obtained after AMA occlusion (P = 0.031). CONCLUSION: A higher infusion rate or AMA occlusion increases the enhanced volume in PIPP in pig models. LEVEL OF EVIDENCE: No level of evidence.

AB - BACKGROUND: Juvenile idiopathic arthritis (JIA) can cause structural damage. However, data on conventional radiography (CR) in JIA are scant. OBJECTIVE: To provide pragmatic guidelines on CR in each non-systemic JIA subtype. METHODS: A multidisciplinary task force of 16 French experts (rheumatologists, paediatricians, radiologists and one patient representative) formulated research questions on CR assessments in each non-systemic JIA subtype. A systematic literature review was conducted to identify studies providing detailed information on structural joint damage. Recommendations, based on the evidence found, were evaluated using two Delphi rounds and a review by an independent committee. RESULTS: 74 original articles were included. The task force developed four principles and 31 recommendations with grades ranging from B to D. The experts felt strongly that patients should be selected for CR based on the risk of structural damage, with routine CR of the hands and feet in rheumatoid factor positive polyarticular JIA but not in oligoarticular non-extensive JIA. CONCLUSION: These first pragmatic recommendations on CR in JIA rely chiefly on expert opinion, given the dearth of scientific evidence. CR deserves to be viewed as a valuable tool in many situations in patients with JIA. KEY POINTS: * CR is a valuable imaging technique in selected indications. * CR is routinely recommended for peripheral joints, when damage risk is high. * CR is recommended according to the damage risk, depending on JIA subtype. * CR is not the first-line technique for imaging of the axial skeleton.

AB - OBJECTIVES: To investigate current practices and perceptions of imaging in necrotising enterocolitis (NEC) according to involved specialists, put them in the context of current literature, and identify needs for further investigation. METHODS: Two hundred two neonatologists, paediatric surgeons, and radiologists answered a web-based questionnaire about imaging in NEC at their hospitals. The results were descriptively analysed, using proportion estimates with 95% confidence intervals. RESULTS: There was over 90% agreement on the value of imaging for confirmation of the diagnosis, surveillance, and guidance in decisions on surgery as well as on abdominal radiography as the first-choice modality and the most important radiographic signs. More variation was observed regarding some indications for surgery and the use of some ultrasonographic signs. Fifty-eight per cent stated that ultrasound was used for NEC at their hospital. Examination frequency, often once daily or more but with considerable variations, and projections used in AR were usually decided individually rather than according to fixed schedules. Predicting the need of surgery was regarded more important than formal staging. CONCLUSION: Despite great agreement on the purposes of imaging in NEC and the most important radiographic signs of the disease, there was considerable diversity in routines, especially regarding examination frequency and the use of ultrasound. Apart from continuing validation of ultrasound, important objectives for future studies include definition of the supplementary roles of both imaging modalities in relation to other diagnostic parameters and evaluation of various imaging routines in relation to timing of surgery, complications, and mortality rate. KEY POINTS: * Imaging is an indispensable tool in the management of necrotising enterocolitis * Predicting the need of surgery is regarded more important than formal staging * There is great consensus on important signs of NEC on abdominal radiography * There is more uncertainty regarding the role of ultrasound * Individualised management is preferred over standardised diagnostic algorithms.

AB - Irisin, a myokine produced by skeletal muscle in response to physical exercise, promotes trans-differentiation of white adipose tissue into brown adipose tissue. Recent evidences suggested that irisin also plays an important role in the control of bone metabolism. This study aimed to ascertain the relationship between plasma irisin and bone mineral density (BMD) in Chinese population by adoption of an extreme sampling method. Based on a large and screened Chinese elderly population (N = 6308), two subgroups with extremely high and low hip BMD were selected for discovery (N = 80, high vs. low BMD = 44:36) and validation (N = 60, high vs. low BMD = 30:30), respectively. Plasma irisin, P1NP, and beta-CTx were measured using commercially available ELISA kits. Other metabolic parameters (e.g., blood glucose, total cholesterol and triglycerides) were collected. Student's t test and Spearman correlation analyses were conducted in SPSS. Significant difference was discovered for plasma irisin between females and age matched males (N = 80, male vs. female = 42:38, P = 0.002). The plasma irisin levels were significantly higher in high BMD subjects than in low BMD subjects, which was observed in both discovery (P = 0.012) and validation samples (P = 0.022). However, such observation was limited to males only. Further correlation analyses in males showed that plasma irisin was correlated with BMD (r = 0.362, P = 0.025) and triglyceride (r = - 0.354, P = 0.032). Plasma irisin levels were associated with hip BMD in Chinese elderly men. This study represented the first effort of investigating the relationship of plasma irisin and BMD in elderly population. The positive correlation between plasma irisin and BMD hints intrinsic communication between muscle and bone. PMID- 29582133 TI - Marrow Adipose Tissue in Older Men: Association with Visceral and Subcutaneous Fat, Bone Volume, Metabolism, and Inflammation. AB - Marrow (MAT) and subcutaneous (SAT) adipose tissues display different metabolic profiles and varying associations with aging, bone density, and fracture risk. Using a non-invasive imaging methodology, we aimed to investigate the associations between MAT, SAT, and visceral fat (VAT) with bone volume, bone remodeling markers, insulin resistance, and circulating inflammatory mediators in a population of older men. In this cross-sectional study, 96 healthy men (mean age 67 +/- 5.5) were assessed for anthropometric parameters, body composition, serum biochemistry, and inflammatory panel. Using single-energy computed tomography images, MAT (in L2 and L3 and both hips), VAT, and SAT (at the level of L2-L3 and L4-L5) were measured employing Slice-O-Matic software (Tomovision), which enables specific tissue demarcation applying previously reported Hounsfield unit thresholds. MAT volume was similar in all anatomical sites and independent of BMI. In all femoral regions of interest (ROIs) there was a strong negative association between bone and MAT volumes (r = - 0.840 to - 0.972, p < 0.001), with location-dependent variations in the lumbar spine. Unlike VAT and SAT, no associations between MAT and serum glucose, inflammatory markers or insulin resistance indicators were found. Bone decline occurred without red marrow expansion; thus lost bone was mainly (if not exclusively) replaced by MAT. In conclusion, strong inverse correlations between MAT and bone mass, which have been previously observed in women, were also confirmed in older men. However, MAT volume in all ROIs was interrelated and unlike women, mainly independent of VAT or SAT. The lack of strong association between MAT vs VAT/SAT, and its discordant associations with metabolic and inflammatory mediators provide further evidence on MAT's distinct attributes in older men. PMID- 29582135 TI - Forensic molecular genetic diversity analysis of Chinese Hui ethnic group based on a novel STR panel. AB - In present study, the genetic polymorphisms of 22 autosomal short tandem repeat (STR) loci were analyzed in 496 unrelated Chinese Xinjiang Hui individuals. These autosomal STR loci were multiplex amplified and genotyped based on a novel STR panel. There were 246 observed alleles with the allele frequencies ranging from 0.0010 to 0.3609. All polymorphic information content values were higher than 0.7. The combined power of discrimination and the combined probability of exclusion were 0.999999999999999999999999999426766 and 0.999999999860491, respectively. Based on analysis of molecular variance method, genetic differentiation analysis between the Xinjiang Hui and other reported groups were conducted at these 22 loci. The results indicated that there were no significant differences in statistics between Hui group and Northern Han group (including Han groups from Hebei, Henan, Shaanxi provinces), and significant deviations with Southern Han group (including those from Guangdong, Guangxi provinces) at 7 loci, and Uygur group at 10 loci. To sum up, these 22 autosomal STR loci were high genetic polymorphic in Xinjiang Hui group. PMID- 29582134 TI - Effects of the recombinant crustacean hyperglycemic hormones rCHH-B1 and rCHH-B2 on the osmo-ionic regulation of the shrimp Litopenaeus vannamei exposed to acute salinity stress. AB - The Pacific white shrimp Litopenaeus vannamei is a euryhaline organism that copes with salinity fluctuations in the environment; therefore, its osmotic and ionic regulation abilities are vital. Osmoregulation may be controlled by the crustacean hyperglycemic hormone (CHH), a neuropeptide mainly expressed in the eyestalks. In L. vannamei, CHH-B1 and CHH-B2 are CHH isoforms isolated from the eyestalks whose expression is influenced by environmental salinity. It has been suggested that they are involved in the response to salinity stress. To clarify this, we investigated the effect of the recombinant peptides, rCHH-B1 and rCHH B2, on the osmo-ionic regulation of shrimp acutely exposed to different salinity conditions (8, 26 and 450/00). Both rCHHs promoted differential effects on the osmoregulatory capacity (OC) and the ionoregulatory capacity (IC) for hemolymph Na+ and Cl- during iso-osmotic (260/00) and hyper-osmotic (450/00) transfers. These changes were linked to the changes observed in Na+/K+ ATPase and carbonic anhydrase gene expression in gills, especially under high salinity conditions, suggesting that the hormones may regulate the expression of these genes. Glucose and protein levels measured during acute salinity transfer suggest their roles as sources of metabolic energy for osmotic regulation or as organic osmolytes. These results taken together suggest that both the CHH-B1 and CHH-B2 peptides are important regulators of the physiological response of L. vannamei to acute salinity fluctuations. PMID- 29582136 TI - Unexplained cardiac arrest: a tale of conflicting interpretations of KCNQ1 genetic test results. AB - OBJECTIVE: Unexplained cardiac arrest (UCA) is often the first manifestation of an inherited arrhythmogenic disease. Genetic testing in UCA is challenging due to the complexities of variant interpretation in the absence of supporting cardiac phenotype. We aimed to investigate if a KCNQ1 variant [p.(Pro64_Pro70del)], previously reported as pathogenic, contributes to the long-QT syndrome phenotype, co-segregates with disease or affects KCNQ1 function in vitro. METHODS: DNA was extracted from peripheral blood of a 22-year-old male after resuscitation from UCA. Targeted exome sequencing was performed using the TruSight-One Sequencing Panel (Illumina). Variants in 190 clinically relevant cardiac genes with minor allele frequency < 1% were analyzed according to the guidelines of the American College of Medical Genetics. Functional characterization was performed using site directed mutagenesis, expression in Xenopus laevis oocytes using the two electrode voltage-clamp technique. RESULTS: The 12-lead ECG, transthoracic echocardiography and coronary angiography after resuscitation showed no specific abnormalities. Two variants were identified: c.190_210del in-frame deletion in KCNQ1 (p.Pro64_Pro70del), reported previously as pathogenic and c.2431C > A in PKP2 (p.Arg811Ser), classified as likely benign. Two asymptomatic family members with no evident phenotype hosted the KCNQ1 variant. Functional studies showed that the wild-type and mutant channels have no significant differences in current levels, conductance-voltage relationships, as well as activation and deactivation kinetics, in the absence and presence of the auxiliary subunit KCNE1. CONCLUSIONS: Based on our data and previous reports, available evidence is insufficient to consider the variant KCNQ1:c.190_210del as pathogenic. Our findings call for cautious interpretation of genetic tests in UCA in the absence of a clinical phenotype. PMID- 29582137 TI - Diversity and common themes in the organization of ocelli in Hymenoptera, Odonata and Diptera. AB - We show in a comparative analysis that distinct retinal specializations in insect ocelli are much more common than previously realized and that the rhabdom organization of ocellar photoreceptors is extremely diverse. Hymenoptera, Odonata and Diptera show prominent equatorial fovea-like indentations of the ocellar retinae, where distal receptor endings are furthest removed from the lens surface and receptor densities are highest. In contrast, rhabdomere arrangements are very diverse across insect groups: in Hymenoptera, with some exceptions, pairs of ocellar retinular cells form sheet-like rhabdoms that form elongated rectangular shapes in cross-section, with highly aligned microvilli directions perpendicular to the long axis of cross-sections. This arrangement makes most ocellar retinular cells in Hymenoptera sensitive to the direction of polarized light. In dragonflies, triplets of retinular cells form a y-shaped fused rhabdom with microvilli directions oriented at 60 degrees to each other. In Dipteran ocellar retinular cells microvilli directions are randomised, which destroys polarization sensitivity. We suggest that the differences in ocellar organization between insect groups may reflect the different head attitude control systems that have evolved in these insect groups, but possibly also differences in the mode of locomotion and in the need for celestial compass information. PMID- 29582138 TI - A lake classification concept for a more accurate global estimate of the dissolved inorganic carbon export from terrestrial ecosystems to inland waters. AB - The magnitude of lateral dissolved inorganic carbon (DIC) export from terrestrial ecosystems to inland waters strongly influences the estimate of the global terrestrial carbon dioxide (CO2) sink. At present, no reliable number of this export is available, and the few studies estimating the lateral DIC export assume that all lakes on Earth function similarly. However, lakes can function along a continuum from passive carbon transporters (passive open channels) to highly active carbon transformers with efficient in-lake CO2 production and loss. We developed and applied a conceptual model to demonstrate how the assumed function of lakes in carbon cycling can affect calculations of the global lateral DIC export from terrestrial ecosystems to inland waters. Using global data on in-lake CO2 production by mineralization as well as CO2 loss by emission, primary production, and carbonate precipitation in lakes, we estimated that the global lateral DIC export can lie within the range of [Formula: see text] to [Formula: see text] Pg C yr-1 depending on the assumed function of lakes. Thus, the considered lake function has a large effect on the calculated lateral DIC export from terrestrial ecosystems to inland waters. We conclude that more robust estimates of CO2 sinks and sources will require the classification of lakes into their predominant function. This functional lake classification concept becomes particularly important for the estimation of future CO2 sinks and sources, since in-lake carbon transformation is predicted to be altered with climate change. PMID- 29582139 TI - Live cell analyses of synaptonemal complex dynamics and chromosome movements in cultured mouse testis tubules and embryonic ovaries. AB - During mammalian meiotic prophase, homologous chromosomes connect through the formation of the synaptonemal complex (SC). SYCP3 is a component of the lateral elements of the SC. We have generated transgenic mice expressing N- or C-terminal fluorescent-tagged SYCP3 (mCherry-SYCP3 (CSYCP) and SYCP3-mCherry (SYCPC)) to study SC dynamics and chromosome movements in vivo. Neither transgene rescued meiotic aberrations in Sycp3 knockouts, but CSYCP could form short axial element like structures in the absence of endogenous SYCP3. On the wild-type background, both fusion proteins localized to the axes of the SC together with endogenous SYCP3, albeit with delayed initiation (from pachytene) in spermatocytes. Around 40% of CSYCP and SYCPC that accumulated on the SC was rapidly exchanging with other tagged proteins, as analyzed by fluorescent recovery after photobleaching (FRAP) assay. We used the CSYCP transgenic mice for further live cell analyses and observed synchronized bouquet configurations in living cysts of two or three zygotene oocyte nuclei expressing CSYCP, which presented cycles of telomere clustering and dissolution. Rapid chromosome movements were observed in both zygotene oocytes and pachytene spermatocytes, but rotational movements of the nucleus were more clear in oocytes. In diplotene spermatocytes, desynapsis was found to proceed in a discontinuous manner, whereby even brief chromosome re association events were observed. Thus, this live imaging approach can be used to follow changes in the dynamic behavior of the nucleus and chromatin, in normal mice and different infertile mouse models. PMID- 29582140 TI - Parental care compromises feeding in the pumpkinseed (Lepomis gibbosus). AB - Providing parental care is potentially costly. Costs can arise through elevated energy expenditure or from an increased risk of mortality. A cost of parental care can also occur because a parent is compromised in their ability to forage. We used pumpkinseed Lepomis gibbosus, a fish with an alternative male mating strategy, to test whether parental males differed in their feeding in comparison with females and cuckolder males. To address this question, we examined the stomach contents of female, cuckolder male, and parental male pumpkinseed during the breeding season over an entire diel cycle. We showed that parental males had a lower total weight of food in their stomachs in comparison with females, while cuckolder males did not. Parental males also had a lower weight and number of chironomids in their stomachs. The temporal pattern of feeding of parental males diverged from that of females, and they had a lower probability of pupal chironomids in their stomachs, which implies spatial segregation in foraging. Parental males had a greater probability of conspecific eggs in their stomachs than females, while the probability of egg cannibalism did not differ between cuckolder males and females. Overall, these finding meet predictions in accordance with an assumption that parental care and territoriality can compromise feeding. PMID- 29582141 TI - Diagnosis of glenoid labral tears using 3-tesla MRI vs. 3-tesla MRA: a systematic review and meta-analysis. AB - BACKGROUND: Various protocols exist for magnetic resonance arthrogram (MRA) of the shoulder, including 3D isotropic scanning and positioning in neutral (2D neutral MRA), or abduction-external-rotation (ABER). HYPOTHESIS: MRA does not improve diagnostic accuracy for labral tears when compared to magnetic resonance imaging (MRI) performed using 3-Tesla (3T) magnets. METHOD: Systematic review of the Cochrane, MEDLINE, and PubMed databases according to PRISMA guidelines. Included studies compared 3T MRI or 3T MRA (index tests) to arthroscopic findings (reference test). Methodological appraisal performed using QUADAS-2. Pooled sensitivity and specificity were calculated. RESULTS: Ten studies including 929 patients were included. Index test bias and applicability were a concern in the majority of studies. The use of arthroscopy as the reference test raised concern of verification bias in all studies. For anterior labral lesions, 3T MRI was less sensitive (0.83 vs. 0.87 p = 0.083) than 3T 2D neutral MRA. Compared to 3T 2D neutral MRA, both 3T 3D Isotropic MRA and 3T ABER MRA significantly improved sensitivity (0.87 vs. 0.95 vs. 0.94). For SLAP lesions, 3T 2D neutral MRA was of similar sensitivity to 3T MRI (0.84 vs. 0.83, p = 0.575), but less specific (0.99 vs. 0.92 p < 0.0001). For posterior labral lesions, 3T 2D neutral MRA had greater sensitivity than 3T 3D Isotropic MRA and 3T MRI (0.90 vs. 0.83 vs. 0.83). CONCLUSIONS: At 3-T, MRA improved sensitivity for diagnosis of anterior and posterior labral lesions, but reduced specificity in diagnosis of SLAP tears. 3T MRA with ABER positioning further improved sensitivity in diagnosis of anterior labral tears. LEVEL OF EVIDENCE: IV. PMID- 29582142 TI - Land surface temperature estimating in urbanized landscapes using artificial neural networks. AB - Scenario-based land surface temperature (LST) modeling is a powerful tool for adopting proper urban land use planning policies. In this study, using greater Isfahan as a case study, the artificial neural network (ANN) algorithm was utilized to explore the non-linear relationships between urban LST and green cover spatial patterns derived from Landsat 8 OLI imagery. The model was calibrated using two sets of variables: Normalized Difference Built Index (NDBI) and Normalized Difference Vegetation Index (NDVI). Furthermore, Compact Development Scenario (CDS) and Green Development Scenario (GDS) were defined. The results showed that GDS is more successful in mitigating urban LST (mean LST = 40.93) compared to CDS (mean LST = 44.88). In addition, urban LST retrieved from the CDS was more accurate in terms of ANOVA significance (sig = 0.043) than the GDS (sig = 0.010). The findings of this study suggest that developing green spaces is a key strategy to combat against the risk of LST concerns in urban areas. PMID- 29582144 TI - Peritoneal drainage in pneumoperitoneum in extremely low birth weight infants. AB - : The aim was to determine if peritoneal drainage (PD) is a suitable treatment for pneumoperitoneum in extremely low birth weight (ELBW) infants. A retrospective chart review of 42 ELBW infants with pneumoperitoneum at the University Hospital of Cologne between November 2014 and April 2017 was performed. Forty-two infants with a median birth weight of 645 g (interquartile range (IQR) 550, 806) and a median gestational age of 24.3 weeks (IQR 23.2, 25.6) were treated for pneumoperitoneum. Twenty-six (62%) received PD, and in ten (38%), the drain could be removed without further intervention. Infants in the PD group were of significantly lower birth weight (622g vs. 750 g), age (4.5 vs. 10.0 days), and weight at diagnosis (538 vs. 778 g). The mortality in the PD group was 15% at 90 days of life, but no patient deceased in the primary laparotomy group. CONCLUSION: We suggest PD with close evaluation of drainage and clinical course as an alternative treatment for pneumoperitoneum in ELBW infants allowing bridging the vulnerable first days of life until these infants are in a more stable condition. Despite not reaching statistical significance in our series, PD showed the trend towards higher mortality. What is known: * Pneumoperitoneum is traditionally treated with laparotomy, but placement of peritoneal drainage (PD) is a valuable treatment option. * Previous randomized controlled trials have shown no significant differences in mortality for PD versus laparotomy. What is new: * In our cohort, 38% of the infants with PD could be saved from secondary laparotomy, but in the PD group there was a trend towards higher mortality. * PD allows bridging the vulnerable first days of life until ELBW infants are in a more stable condition for possible laparotomy. PMID- 29582143 TI - Genetic contribution to vestibular diseases. AB - Growing evidence supports the contribution of allelic variation to vestibular disorders. Heritability attributed to rare allelic variants is found in familial vestibular syndromes such as enlarged vestibular aqueduct syndrome or familial Meniere disease. However, the involvement of common allelic variants as key regulators of physiological processes in common and rare vestibular diseases is starting to be deciphered, including motion sickness or sporadic Meniere disease. The genetic contribution to most of the vestibular disorders is still largely unknown. This review will outline the role of common and rare variants in human genome to episodic vestibular syndromes, progressive vestibular syndrome, and hereditary sensorineural hearing loss associated with vestibular phenotype. Future genomic studies and network analyses of omic data will clarify the pathway towards a personalized stratification of treatments. PMID- 29582145 TI - Enhanced recovery after posterior minimally invasive total hip arthroplasty with continuous intraarticular anaesthesia. AB - BACKGROUND: The aim of this study was to evaluate the possible complications specific to the continuous intraarticular anaesthesia (CIA) in a minimally invasive posterior approach in total hip arthroplasty and its possible effects on the recovery, especially on pain and the length of hospitalisation. MATERIALS AND METHODS: The surgical procedure is first precisely described step by step with numerous per-operating photographs. Particular technical points are detailed. The errors to be avoided are specified. A prospective series of 70 first-line total hip arthroplasties (one half with and one half without CIA) are analysed for the well-known results of total hip arthroplasty but specifically assessing: (a) specific possible complications to the minimally invasive posterior technique with the prolonged local anaesthesia and (b) effects on pain, duration of hospitalisation and satisfaction in patients (questionnaire). RESULTS: (a) Very low level of immediate post-operative pain was observed in almost all of the patients. (b) Patient satisfaction was high in our series. (c) A repeated education was provided multiple times to avoid specific complications following the absence of pain and consequent inattention. DISCUSSION AND CONCLUSION: The minimally invasive posterior approach with continuous intraarticular anaesthesia is an entirely reliable hip arthroplasty procedure. The patients exhibited a significantly less pain and a fast rate of recovery, but preparatory education must be even more significant.

AB - Adequacy of dialysis is a term that has been used for many years based on measurement of small solute clearance using urea and creatinine. This has been shown in some but not all studies in adults to correlate with survival. However, small solute clearance is just one minor part of the effectiveness of dialysis and in fact 'optimum' dialysis, rather than 'adequate' dialysis is what most paediatric nephrologists would want for their patients. Additional ways to assess the success of dialysis in children would include dialysis access complications and longevity, preservation of residual kidney function, body composition, biochemical and haematological control, nutrition and growth, discomfort during the dialysis process and psychosocial adjustment including hospitalisation and school attendance. These criteria need to be balanced against a dialysis programme that has the least possible adverse effects on quality of life. PMID- 29582149 TI - Obtaining central access in challenging pediatric patients. AB - PURPOSE: Central catheter placement is one of the most commonly performed procedures by pediatric surgeons. Here, we present a case series of patients where central access was obtained at our institution with the utilization of a novel ultrasound-guided technique. This series represents the first of its kind where the native, parent vessels were inaccessible, resulting in a challenging situation for providers. METHODS: A retrospective chart review was performed in pediatric patients (0-17 years) at a tertiary care institution between July 2012 and November 2017 on all central line procedures where ultrasound was utilized to cannulate the brachiocephalic or superior vena cava in face of proximal occlusion. Our group has previous experience utilizing an image-guided in-plane approach to central line placement in the pediatric population. Demographics, operative characteristics, and postoperative complications were reviewed. RESULTS: A total of 11 procedures were included in this case series where the BC (N = 9) or SVC (N = 2) were cannulated for access. Internal jugular vein cannulation was attempted on each patient unless preoperative imaging demonstrated occlusion. The median operative time was 43 +/- 23 min. Most procedures were performed on the right sided (63%), with catheters ranging from 4.2F single lumen to 14F double lumen. Since being placed, three (27%) catheters have been removed, with one due to non-use, one due to sepsis, and the final one due to malposition. CONCLUSION: With the continued need for long-term central access in the pediatric population, distal vein occlusion or inaccessibility can prove challenging when attempting to obtain central access. Here, demonstrated a safe alternative technique that provides an additional option in the pediatric surgeon's armamentarium for patients with difficult central access. PMID- 29582150 TI - Evaluation of artifact-corrected electroencephalographic (EEG) training: a pilot study. AB - This double-blind study examined the effect of electromyographical (EMG) artifacts, which contaminate electroencephalographical (EEG) signals, by comparing artifact-corrected (AC) and non-artifact-corrected (NAC) neurofeedback (NF) training procedures. 14 unmedicated college students were randomly assigned to two groups: AC (n = 7) or NAC (n = 7). Both groups received 12 sessions of NF and were trained using identical NF treatment protocols to reduce their theta/beta power ratios (TBPR). Outcomes on a continuous performance test revealed that the AC group had statistically significant increases across measures of auditory and visual attention. The NAC group showed smaller gains that only reached statistical significance on measures of visual attention. Only the AC group reduced their TBPR, the NAC group did not. AC NF appears to play an important role during training that leads to improvements in both auditory and visual attention. Additional research is required to confirm the results of this study. PMID- 29582152 TI - Implementation and evaluation of an interdisciplinary preventive program to prevent early childhood caries. AB - OBJECTIVES: Since early childhood caries (ECC) is a major disease in the public health sector, an interdisciplinary prevention concept to avert this disease was developed, launched in a project region, and evaluated. It was examined whether the emergence of ECC could be prevented or curbed with the newly developed program. MATERIALS AND METHODS: The program encompasses seven pulses of information from an interdisciplinary team (gynecologists, midwives, pediatricians, dentists, municipal social services, and the public health office). The primary dependent variables were caries experience and prevalence among the 3- to 4-year-olds who took part in the ECC prevention program, compared to children of the same age without such measures. The effect of the prevention program was assessed by means of a "historical" comparison. The dental diagnoses were performed by two calibrated dentists based on the "ICDAS collapsed." Data on diet and preventive behavior were gathered using a standardized parental questionnaire. The significance was tested using the nonparametric Mann-Whitney U test. RESULTS: There were 661 3- to 4-year-olds in the control group and 706 in the test group. The mean d3-6mf-t for the control group (0.92) was significantly higher than that for the test group (0.46). While 78.8% of the children examined in the control group exhibited predominantly sound primary dentition, this was the case for 86.3% of the test group. The proportion of children with S-ECC was 7.9% in the test group and 14.5% in the control group. The test group differed significantly from the control group both in terms of reported diet and dental hygiene habits. CONCLUSIONS AND CLINICAL RELEVANCE: The interdisciplinary prevention program presented here is an effective concept for preventing ECC and considerably helps reduce problems in the treatment of small children. PMID- 29582151 TI - Bacterial exopolysaccharides as a modern biotechnological tool for modification of fungal laccase properties and metal ion binding. AB - Four bacterial EPSs extracted from Rhizobium leguminosarum bv. trifolii Rt24.2, Sinorhizobium meliloti Rm1021, Bradyrhizobium japonicum USDA110, and Bradyrhizobium elkanii USDA76 were determined towards their metal ion adsorption properties and possible modification of Cerrena unicolor laccase properties. The highest magnesium and iron ion-sorption capacity (~ 42 and ~ 14.5%, respectively) was observed for EPS isolated from B. japonicum USDA110. An evident influence of EPSs on the stability of laccase compared to the control values (without EPSs) was shown after 30-day incubation at 25 degrees C. The residual activity of laccases was obtained in the presence of Rh76EPS and Rh1021EPS, i.e., 49.5 and 41.5% of the initial catalytic activity, respectively. This result was confirmed by native PAGE electrophoresis. The EPS effect on laccase stability at different pH (from 3.8 to 7.0) was also estimated. The most significant changes at the optimum pH value (pH 5.8) was observed in samples of laccase stabilized by Rh76EPS and Rh1021EPS. Cyclic voltamperometry was used for analysis of electrochemical parameters of laccase stabilized by bacterial EPS and immobilized on single-walled carbon nanotubes (SWCNTs) with aryl residues. Laccases with Rh76EPS and Rh1021EPS had an evident shift of the value of the redox potential compared to the control without EPS addition. In conclusion, the results obtained in this work present a new potential use of bacterial EPSs as a metal-binding component and a modulator of laccase properties especially stability of enzyme activity, which can be a very effective tool in biotechnology and industrial applications. PMID- 29582153 TI - Predictive factors of neurological recovery after chronic craniovertebral brainstem compression. AB - BACKGROUND: Neurologic manifestations of craniovertebral junction (CVJ) disease may generate dramatic brainstem damage, which could evolve to paralysis. In most cases, patients are referred with advanced neurological symptoms such as tetraplegia/paresis. The aim of this study was to identify predictive factors of favorable neurological evolution after non-traumatic brainstem compression. METHODS: A prospective study evaluated 143 consecutive patients who had undergone CVJ anterior brainstem decompression. The mean age was 45.1 +/- 19.1 years. The study analyzed clinical, surgical, and imagery characters to determine predictive factors of neurological improvement. RESULTS: The mean follow-up of our series was 10.2 years (range 0.5-23.9). Seventy-one (49.6%) presented initial tetrapalsies resulting from spinal cord compression. Multivariable analysis revealed that Frankel score [odds ratio (OR) 5.7, CI 95% 1.01-31.8; p < 0.04] and preoperative symptoms < 6 months [OR 0.33, CI 95% 0.125-0.9; p < 0.025] were independently associated with partial neurological improvement, while the only independent factor associated with total neurologic recovery was the preoperative symptom evolution <6 months [odd ratio (OR) 4.3, CI 95% 1.6-11.4; p < 0.003]. None of the following were identified as predictive factors: demographic characteristics, medical history, the etiology of compression, or initial spinal cord MRI. CONCLUSION: The earlier the decompression is performed, the better the neurological improvement. Whatever the initial Frankel score, if neurological palsy or disorders evolved for less than 6 months, complete recovery is possible.

PMID- 29582154 TI - Association of body mass index with chronic pain prevalence: a large population based cross-sectional study in Japan. AB - PURPOSE: The aim of this study was to examine the association between body mass index and chronic pain. METHODS: The outcome was chronic pain prevalence by body mass index (BMI). BMIs of less than 18.5, 18.5-25.0, 25.0-30.0, and 30.0 or over kg/m2 were defined as underweight, normal weight, overweight, and obese. SUBJECTS: We used data from 4993 participants (2464 men and 2529 women aged 20-79 years) of the Pain Associated Cross-sectional Epidemiological survey in Japan. Sex-stratified multivariable-adjusted odds ratios were calculated with 95% confidence intervals using a logistic regression model including age, smoking, exercise, sleep time, monthly household expenditure, and presence of severe depression. We analyzed all ages and age subgroups, 20-49 and 50-79 years. RESULTS: The prevalence of chronic pain was higher among underweight, overweight, and obese male respondents than those reporting normal weight, with multivariable odds ratios of 1.52 (1.03-2.25), 1.55 (1.26-1.91), and 1.71 (1.12-2.60). According to underweight, only older men showed higher prevalence of chronic pain than normal weight men with odd ratios, 2.19 (1.14-4.20). Being overweight and obese were also associated with chronic pain in women; multivariable odds ratios were 1.48 (1.14-1.93) and 2.09 (1.20-3.64). Being underweight was not associated with chronic pain. CONCLUSION: There was a U-shaped association between BMI and chronic pain prevalence among men >= 50 years, and a dose-response association among women. Our finding suggests that underweight should be considered in older men suffering chronic pain. PMID- 29582156 TI - Groundwater contamination by polycyclic aromatic hydrocarbon due to diesel spill from a telecom base station in a Nigerian City: assessment of human health risk exposure. AB - Diesel pollution of groundwater poses great threat to public health, mainly as a result of the constituent polycyclic aromatic hydrocarbons (PAHs). In this study, the human health risk exposure to polycyclic aromatic hydrocarbons (PAHs) in diesel contaminated groundwater used by several families at Ring Road, Jos, Nigeria (as caused by diesel spill from a telecom base station) was assessed. Prior to the groundwater being treated, the residents were using the water after scooping off the visible diesel sheen for purposes of cooking, washing, and bathing. Until this study, it is not clear whether the groundwater contamination had resulted in sub-chronic exposure of the residents using the water to polycyclic aromatic hydrocarbons (PAHs) to the extent of the PAHs posing a health risk. The diesel contaminated groundwater and uncontaminated nearby groundwater (control) were collected and analyzed for PAHs using gas chromatography-mass spectrometry (GC-MS). The dosage of the dermal and oral ingestion entry routes of PAHs was determined. The estimation of the non-carcinogenic health risk was via hazard quotients (HQ) and the associated hazard index (HI), while the estimation of the carcinogenic health risk was via lifetime cancer risks (LCR) and the associated risk index (RI). Obtained results indicate that the exposure of the residents to the PAHs may have made them susceptible to the risk of non carcinogenic health effects of benzo(a)pyrene and the carcinogenic health effects of benzo(a)anthracene and benzo(a)pyrene. PMID- 29582157 TI - Next-generation sequencing reveals genetic landscape in 46, XY disorders of sexual development patients with variable phenotypes. AB - Disorders of sexual development (DSD) are rare congenital conditions in which chromosomal, gonadal, or anatomical sex is atypical. Currently, less than 20% of patients receive an accurate genetic diagnosis. Targeted next-generation sequencing, consisting of 33 candidate genes and 47 genes involved in sexual differentiation and development, was performed on 70 46, XY DSD patients. Functional assays were performed to evaluate the expression and transcriptional activity of one reported and nine novel mutations of NR5A1. In total, 113 mutations, including 86 novel and 27 reported sites in 40 genes, were identified in 52 patients. Among them, 37 mutations from 19 genes were first identified in 46, XY DSD patients, including EGF, LHX9, and CST9. Nine patients displayed biallelic mutations, 12 had mutations in sex chromosome genes and 14 had monoallelic mutations in NR5A1, BMP4, and WT1. Higher frequency mutations were identified in AR, SRD5A2, and NR5A1. Six missense, one frameshift, and one three nucleotide deletion mutations of NR5A1 were shown to impair the transactivation ability with an altered nuclear aggregation of p.T29K and p.N44del variants. Multiple genetic mutations were identified in 33 of the 70 patients. The targeted sequencing panel provides an efficient method for the etiological diagnosis of 46, XY DSD patients and expands the candidate genes and inherited patterns. PMID- 29582158 TI - Demonstrating PM2.5 and road-side dust pollution by heavy metals along Thika superhighway in Kenya, sub-Saharan Africa. AB - This study assessed the level of heavy metal in roadside dust and PM2.5 mass concentrations along Thika superhighway in Kenya. Thika superhighway is one of the busiest roads in Kenya, linking Thika town with Nairobi. Triplicate road dust samples collected from 12 locations were analysed for lead (Pb), chromium (Cr), cadmium (Cd), nickel (Ni), zinc (Zn), and copper (Cu) using atomic absorption spectrophotometry (AAS). PM2.5 samples were collected on pre-weighed Teflon filters using a BGI personal sampler and the filters were then reweighed. The ranges of metal concentrations were 39-101 MUg/g for Cu, 95-262 MUg/g for Zn, 9 28 MUg/g for Cd, 14-24 MUg/g for Ni, 13-30 MUg/g for Cr, and 20-80 MUg/g for Pb. The concentrations of heavy metals were generally highly correlated, indicating a common anthropogenic source of the pollutants. The results showed that the majority of the measured heavy metals were above the background concentration, and in particular, Cd, Pb, and Zn levels indicated moderate to high contamination. Though not directly comparable due to different sampling timeframes (8 h in this study and 24 h for guideline values), PM2.5 for all sites exceeds the daily WHO PM2.5 guidelines of 25 MUg/m3. This poses a health risk to people using and working close to Thika superhighway, for example, local residents, traffic police, street vendors, and people operating small businesses. PM2.5 levels were higher for sites closer to Nairobi which could be attributed to increased vehicular traffic towards Nairobi from Thika. This study provides some evidence of the air pollution problem arising from vehicular traffic in developing parts of the world and gives an indication of the potential health impacts. It also highlights the need for source apportionment studies to determine contributions of anthropogenic emissions to air pollution, as well as long-term sampling studies that can be used to fully understand spatiotemporal patterns in air pollution within developing regions. PMID- 29582159 TI - In Vitro Assessment of Spray Deposition Patterns in a Pediatric (12 Year-Old) Nasal Cavity Model. AB - PURPOSE: Nasal sprays available for the treatment of cold and allergy symptoms currently use identical formulations and devices for adults as well as for children. Due to the obvious differences between the nasal airway dimensions of a child and those of an adult, the performance of nasal sprays in children was evaluated. METHODS: Deposition patterns of nasal sprays administered to children were tested using a nasal cast based on MRI images obtained from a 12 year old child's nasal cavity. Test formulations emitting a range of spray patterns were investigated by actuating the device into the pediatric nasal cast under controlled conditions. RESULTS: The results showed that the nasal sprays impacted in the anterior region of the 12 year old child's nasal cavity, and only limited spray entered the turbinate region - the effect site for most topical drugs and the primary absorptive region for systemically absorbed drugs. CONCLUSION: Differences in deposition patterns following the administration of nasal sprays to adults and children may lead to differences in efficacy between these populations. Greater anterior deposition in children may result in decreased effectiveness, greater anterior dosage form loss, and the increased potential for patient non-compliance. PMID- 29582161 TI - Sex differences in the association of psychological status with measures of physical activity and sedentary behaviour in adults with type 2 diabetes. AB - AIM: To assess the association of psychological variables on leisure-time physical activity and sedentary time in men and women with type 2 diabetes mellitus (T2D). METHODS: In this cross-sectional study, we evaluated 163 patients with T2D, consecutively recruited at the Diabetes Centre of the Verona General Hospital. Scores on depression and anxiety symptoms, psychosocial factors (including self-efficacy, perceived interference, perceived severity, social support, misguided support behaviour, spouse's positive behaviour), physical activity and time spent sitting were ascertained using questionnaires responses to the Beck Depression Inventory-II, Beck Anxiety Inventory, Multidimensional Diabetes Questionnaire, International Physical Activity Questionnaire. RESULTS: Physical activity was significantly associated with higher social support in women and with increased self-efficacy in men. Sedentary time was significantly associated with higher perceived interference, anxiety and depressive symptoms, and with reduced diabetes self-efficacy in women, while it was associated solely with anxiety in men. Depressive symptoms and self-efficacy in women and anxiety symptoms in men were independent predictors of sedentary time when entered in a multivariable regression model also including age, BMI, haemoglobin A1c, diabetes duration, perceived interference and self-efficacy as covariates. CONCLUSIONS: Lower self-efficacy and higher symptoms of depression were closely associated with increased sedentary time in women, but not in men, with T2D. It is possible that individualized behavioural interventions designed to reduce depressive symptoms and to improve diabetes self-efficacy would ultimately reduce sedentary behaviours, particularly in women with T2D. PMID- 29582160 TI - Screening and diagnosis of gestational diabetes in India: a systematic review and meta-analysis. AB - AIMS: Although diabetes is rapidly increasing in India, there is no national consensus on best practices for screening, diagnosis, and management of gestational diabetes mellitus (GDM). The goal of this study was to systematically review the literature for studies reporting the prevalence and screening and diagnostic methods for gestational diabetes in India. METHODS: We searched MEDLINE, Embase, and POPLINE for studies on screening for GDM in India. We included English-language full reports and conference abstracts of cross sectional studies, prospective, and retrospective cohorts that reported the screening method and prevalence of GDM. We performed descriptive analysis on all studies and meta-analysis, meta-regression, and subgroup meta-analysis on studies with medium or low risk of bias. RESULTS: We included 64 studies reporting 90 prevalence estimates. Prevalence estimates ranged from 0 to 41.9%. Subset meta analyses showed that the IADPSG diagnostic criteria found significantly more GDM cases (prevalence = 19.19% [15.5, 23.6], p < 0.05) than the WHO 1999 criteria (10.13% [8.17, 12.50]) and DIPSI criteria (7.37% [5.2, 10.16]). Studies that compared the IADPSG and WHO 1999 criteria showed poor positive agreement (33 79%). Studies specifying time of GDM diagnosis showed that patients (11-60%) develop GDM as early as the first trimester, but many GDM cases (16-40%) are missed if screened only at first visit. CONCLUSIONS: In India, prevalence estimates of GDM vary substantially by diagnostic criteria. When evaluating screening and diagnostic criteria for GDM, providers should consider their patients' needs and correlate screening criteria with pregnancy outcomes. PMID- 29582162 TI - Low adherence to the western and high adherence to the mediterranean dietary patterns could prevent colorectal cancer. AB - PURPOSE: To assess if the associations found between three previously identified dietary patterns with breast, prostate and gastric cancer are also observed for colorectal cancer (CRC). METHODS: MCC-Spain is a multicase-control study that collected information of 1629 incident cases of CRC and 3509 population-based controls from 11 Spanish provinces. Western, Prudent and Mediterranean data driven dietary patterns-derived in another Spanish case-control study-were reconstructed in MCC-Spain. Their association with CRC was assessed using mixed multivariable logistic regression models considering a possible interaction with sex. Risk by tumor site (proximal colon, distal colon, and rectum) was evaluated using multinomial regression models. RESULTS: While no effect of the Prudent pattern on CRC risk was observed, a high adherence to the Western dietary pattern was associated with increased CRC risk for both males [ORfourth(Q4) vs. first(Q1)quartile (95% CI): 1.45 (1.11;1.91)] and females [ORQ4 vs. Q1 (95% CI): 1.50 (1.07;2.09)] but seem to be confined to distal colon [ORfourth(Q4) vs. first(Q1)quartile (95% CI): 2.02 (1.44;2.84)] and rectal [ORQ4 vs. Q1 (95% CI): 1.46 (1.05;2.01)] tumors. The protective effect of the Mediterranean dietary pattern against CRC was observed for both sexes [males: ORQ4 vs. Q1 (95% CI): 0.71 (0.55;0.92); females: ORQ4 vs. Q1 (95% CI): 0.56 (0.40;0.77)] and for all cancer sites: proximal colon [ORQ4 vs. Q1 (95% CI): 0.70 (0.51;0.97)], distal colon [ORQ4 vs. Q1 (95% CI): 0.65 (0.48;0.89)], and rectum (ORQ4 vs. Q1 (95% CI): 0.60 (0.45;0.81)]. CONCLUSION: Our results are consistent with most of the associations previously found between these patterns and breast, prostate and gastric cancer risk and indicate that consuming whole fruits, vegetables, legumes, olive oil, nuts, and fish and avoiding red and processed meat, refined grains, sweets, caloric drinks, juices, convenience food, and sauces might reduce CRC risk. PMID- 29582163 TI - Co-infection with human polyomavirus BK enhances gene expression and replication of human adenovirus. AB - Immunocompromised patients are susceptible to multiple viral infections. Relevant interactions between co-infecting viruses might result from viral regulatory genes which trans-activate or repress the expression of host cell genes as well as the genes of any co-infecting virus. The aim of the current study was to show that the replication of human adenovirus 5 is enhanced by co-infection with BK polyomavirus and is associated with increased expression of proteins including early region 4 open reading frame 1 and both the large tumor antigen and small tumor antigen. Clinical samples of whole blood and urine from 156 hematopoietic stem cell transplant recipients were tested. We also inoculated adenocarcinomic human alveolar basal epithelial cells with both human adenovirus 5 and BK polyomavirus to evaluate if co-infection of viruses affected their replication. Data showed that adenovirus load was significantly higher in the plasma (mean 7.5 x 103 +/- 8.5 x 102 copies/ml) and urine (mean 1.9 x 103 +/- 8.0 x 102 copies/ml) of samples from patients with co-infections, in comparison to samples from patients with isolated adenovirus infection. In vitro co-infection led to an increased (8.6 times) expression of the adenovirus early region 4 open reading frame gene 48 hours post-inoculation. The expression of the early region 4 open reading frame gene positively correlated with the expression of BK polyomavirus large tumor antigen (r = 0.90, p < 0.0001) and small tumor antigen (r = 0.83, p < 0.001) genes. The enhanced expression of the early region 4 open reading frame gene due to co-infection with BK polyomavirus was associated with enhanced adenovirus, but not BK polyomavirus, replication. The current study provides evidence that co-infection of adenovirus and BK polyomavirus contributes to enhanced adenovirus replication. Data obtained from this study may have significant importance in the clinical setting. PMID- 29582164 TI - Induction of a high-titered antibody response using HIV gag-EV71 VP1-based virus like particles with the capacity to protect newborn mice challenged with a lethal dose of enterovirus 71. AB - Enterovirus 71 (EV71) is the most frequently detected causative agent in hand, foot, and mouth disease (HFMD) and is a serious threat to public health in the Asia-Pacific region. Many EV71 vaccines are under development worldwide, and although both inactivated virus vaccines and virus-like particles (VLPs) are considered to be effective, the main focus has been on inactivated EV71vaccines. There have been very few studies on EV71 VLPs. In this study, using a strategy based on HIV gag VLPs, we constructed a gag-VP1 fusion gene to generate a recombinant baculovirus expressing the EV71 structural protein VP1 together with gag, which was then used to infect TN5 cells to form VLPs. The VLPs were characterized using transmission electron microscopy, electrophoresis and staining with Coomassie blue, and Western blotting. Mice immunized with gag-VP1 VLPs showed strong humoral and cellular immune responses. Finally, immunization of female mice with gag-VP1 VLPs provided effective protection of their newborn offspring against challenge with a lethal dose EV71. These results demonstrate a successful approach for producing EV71 VP1 VLPs based on the ability of HIV gag to self-assemble, thus providing a good foundation for producing high-titered anti-EV71 antibody by immunization with VLP-based gag EV71 VP1 protein. PMID- 29582165 TI - Using genomic analysis to identify tomato Tm-2 resistance-breaking mutations and their underlying evolutionary path in a new and emerging tobamovirus. AB - In September 2014, a new tobamovirus was discovered in Israel that was able to break Tm-2-mediated resistance in tomato that had lasted 55 years. The virus was isolated, and sequencing of its genome showed it to be tomato brown rugose fruit virus (ToBRFV), a new tobamovirus recently identified in Jordan. Previous studies on mutant viruses that cause resistance breaking, including Tm-2-mediated resistance, demonstrated that this phenotype had resulted from only a few mutations. Identification of important residues in resistance breakers is hindered by significant background variation, with 9-15% variability in the genomic sequences of known isolates. To understand the evolutionary path leading to the emergence of this resistance breaker, we performed a comprehensive phylogenetic analysis and genomic comparison of different tobamoviruses, followed by molecular modeling of the viral helicase. The phylogenetic location of the resistance-breaking genes was found to be among host-shifting clades, and this, together with the observation of a relatively low mutation rate, suggests that a host shift contributed to the emergence of this new virus. Our comparative genomic analysis identified twelve potential resistance-breaking mutations in the viral movement protein (MP), the primary target of the related Tm-2 resistance, and nine in its replicase. Finally, molecular modeling of the helicase enabled the identification of three additional potential resistance-breaking mutations. PMID- 29582166 TI - Restoring the IL-1beta/NF-kappaB-induced impaired chondrogenesis by diallyl disulfide in human adipose-derived mesenchymal stem cells via attenuation of reactive oxygen species and elevation of antioxidant enzymes. AB - Strategies based on mesenchymal stem cell (MSC) therapy for restoring injured articular cartilage are not effective enough in osteoarthritis (OA). Due to the enhanced inflammation and oxidative stress in OA microenvironment, differentiation of MSCs into chondrocytes would be impaired. This study aims to explore the effects of diallyl disulfide (DADS) on IL-1beta-mediated inflammation and oxidative stress in human adipose derived mesenchymal stem cells (hADSCs) during chondrogenesis. MTT assay was employed to examine the effects of various concentrations of DADS on the viability of hADSCs at different time scales to obtain non-cytotoxic concentration range of DADS. The effects of DADS on IL-1beta induced intracellular ROS generation and lipid peroxidation were evaluated in hADSCs. Western blotting was used to analyze the protein expression levels of IkappaBalpha (np), IkappaBalpha (p), NF-kappaB (np) and NF-kappaB (p). Furthermore, the gene expression levels of antioxidant enzymes in hADSCs and chondrogenic markers at days 7, 14 and 21 of differentiation were measured using qRT-PCR. The results showed that addition of DADS significantly enhanced the mRNA expression levels of antioxidant enzymes as well as reduced ROS elevation, lipid peroxidation, IkappaBalpha activation and NF-kappaB nuclear translocation in hADSCs treated with IL-1beta. In addition, DADS could significantly increase the expression levels of IL-1beta-induced impaired chondrogenic marker genes in differentiated hADSCs. Treatment with DADS may provide an effective approach to prevent the pro-inflammatory cytokines and oxidative stress as catabolic causes of chondrocyte cell death and enhance the protective anabolic effects by promoting chondrogenesis associated gene expressions in hADSCs exposed to OA condition. PMID- 29582167 TI - Amniotic membrane extract differentially regulates human peripheral blood T cell subsets, monocyte subpopulations and myeloid dendritic cells. AB - The discovery of the immunoregulatory potential of human amniotic membrane (hAM) propelled several studies focusing on its application for the treatment of immunological disorders. However, there is little information regarding the effects of hAM on distinct activation and differentiation stages of immune cells. Here, we aim to investigate the effect of human amniotic membrane extract (hAME) on the pattern of cytokine production by T cells, monocytes and myeloid dendritic cells (mDCs). For this purpose, peripheral blood mononuclear cells (PBMCs) from eight healthy individuals were stimulated in vitro in the presence or absence of hAME. Mitogen-induced proliferation of PBMCs and cytokine production among the distinct T cell functional compartments, monocyte subpopulations and mDCs were evaluated. hAME displayed an anti-proliferative effect and decreased the frequency of T cells producing tumor necrosis factor (TNF)alpha, interferon (IFN)gamma and interleukin (IL)-2, for all T cell functional compartments. The frequency of IL-17 and IL-9-producing T cells was also reduced. The inhibition of mRNA expression of granzyme B, perforin and NKG2D by CD8+ T cells and gammadelta T cells and the augment of FoxP3 and IL-10 in CD4+ T cells and IL-10 in regulatory T cells were also observed. Furthermore, hAME inhibited IFNgamma induced protein (IP)-10 expression by classical and non-classical monocytes, without hampering the production of TNFalpha and IL-6 by monocytes and mDCs. These results suggest that hAME exerts an anti-inflammatory effect on T cells, still at a different extent for distinct T cell functional compartments. PMID- 29582168 TI - Underutilized and Under Threat: Environmental Policy as a Tool to Address Diabetes Risk. AB - PURPOSE OF REVIEW: Diabetes is a burgeoning threat to public health in the USA. Importantly, the burden of diabetes is not equally borne across society with marked disparities based on geography, race/ethnicity, and income. The etiology of global and population-specific diabetes risk remains incompletely understood; however, evidence linking environmental toxicants acting as endocrine-disrupting chemicals (EDCs), such as particulate matter and arsenic, with diabetes suggests that environmental policies could play an important role in diabetes risk reduction. RECENT FINDINGS: Evidence suggests that disproportionate exposures to EDCs may contribute to subgroup-specific diabetes risk; however, no federal policies regulate EDCs linked to diabetes based upon diabetogenic potential. Nevertheless, analyses of European Union data indicate that such regulation could reduce diabetes-associated costs and disease burden. Federal laws only regulate EDCs indirectly. The accumulating evidence linking these chemicals with diabetes risk should encourage policymakers to adopt stricter environmental standards that consider both health and economic impacts. PMID- 29582169 TI - Medulloblastoma, WNT-activated/SHH-activated: clinical impact of molecular analysis and histogenetic evaluation. AB - PURPOSE: Medulloblastoma (MDB) is a small cell poorly differentiated embryonal tumor of the cerebellum, which more frequently compromises children. Overall prognosis is favorable, but dependent of stage, histopathological pattern and molecular group. Approximately 30% of the affected patients will die from the disease. WHO 2016 Classification of Tumors of the Central Nervous System (CNS) has been classified MDB into four principal groups: WNT-activated MDB, SHH activated MDB, group 3 MDB, and group 4 MDB. WNT-activated MDB is associated to monosomy 6, CTNNB1, DDX3X and TP53 mutations, beta-catenin nuclear immunoexpression, and a better prognosis than SHH-activated MDB. DISCUSSION: WNT activated tumors account approximately for 10% of cases of MDBs, and are thought to arise from cells in the dorsal brain stem/lower rhombic lip progenitor cells. SHH-activated MDB more frequently arises in the lateral hemispheres of the cerebellum, and clinical outcome in this group is variable. TP53-mutant SHHactivated MDB usually shows the large cell/anaplastic pattern, and can be related to MYCN amplification, GLI2 amplification and 17p loss. TP53-wildtype SHH activated MDB is more commonly of desmoplastic/nodular morphology, and can be related to PTCH1 deletion and 10q loss. Gene expression and methylation profiling is the gold standard for defining molecular groups of MDB. In immunohistochemistry assays, anti-GAB1 antibody expression is positive in tumors showing SHH pathway activation or PTCH mutation, while positive immunoexpression for YAP1 antibody can be only found in WNT-activated and SHH-activated MDB. PMID- 29582170 TI - Management of split cord malformation in children: the Lyon experience. AB - INTRODUCTION: Split cord malformation (SCM) is a rare congenital spinal abnormality. Clinical presentation varies. Other congenital defects can be associated. Management is surgical. MATERIAL AND METHODS: We retrospectively reviewed all our SCM cases and reported our experience for its management. From 1990 to 2014, 37 patients were operated. Five situations lead to the diagnosis (orthopedic disorders (n = 8), orthopedic and neurological disorders (n = 16), pure neurological disorders (n = 5), no symptoms except cutaneous signs (n = 7), antenatal diagnosis (n = 1)). Scoliosis was the most common associated condition. The level of the spur was always under T7 except in one case. There were more type I (n = 22) than type II (n = 15) SCM. RESULTS: Patients with preoperative neurological symptoms (n = 21) were improved in 71.4%. Five out of nine patients that had preoperative bladder dysfunction were improved. Eleven patients needed surgical correction of the scoliosis. CONCLUSIONS: For us, the surgical procedure is mandatory even in case of asymptomatic discovery in order to avoid late clinical deterioration. In any case, the filum terminale need to be cut in order to untether completely the spinal cord. In case a surgical correction of a spinal deformity is needed, we recommend a two-stage surgery, for both SCM type. The SCM surgery can stop the evolution of the scoliosis and it may just need an orthopedic treatment with a brace. PMID- 29582171 TI - Experience in shunt management on revision free survival in infants with myelomeningocele. AB - OBJECTIVE: Depending on the etiology of hydrocephalus in childhood, the shunt therapy still remains challenging due to frequent shunt complications leading to possible revisions such as shunt infection or shunt malfunction. In myelomeningocele (MMC) patients who often require shunt therapy, higher revisions rates were reported. In a single-center retrospective study, experiences on shunt regimen on hydrocephalus associated with MMC are presented. METHODS: Data of 160 infant hydrocephalus cases younger than 1 year of age at the time of implantation were retrospectively reviewed from the hospital database. These patients received an adjustable differential pressure valve with gravitational unit and antibiotic impregnated catheters as a primary or secondary implant during the time period of April 2007 to July 2015. The subgroup of infants cases with MMC (n = 44; age 50.6 +/- 80.6 days) were compared to the remaining cohort of other hydrocephalus etiology (control group). The shunt and valve revision free survival rates were recorded until July 2017. RESULTS: During the mean follow-up of 48.7 +/- 19.2 (7 114) months, the shunt revision free survival was 87% at 1 year and 49% at 60 months in the MMC cohort. The control group showed a shunt survival rate of 68% at 1 year and 39% at 60 months. Similarly, the valve revision free survival rate showed a significant higher rate of 92% at 1 year and 69% at 60 months in the MMC group compared to the control group (75% at 1 year and 51% at 60 months; p < 0.05). During the entire follow-up period, 37% of the MMC infants underwent a revision operation in contrast to the control group of 40%. CONCLUSION: The presented shunt strategy showed improved revision free survival rates in infants with a MMC-related hydrocephalus in comparison to other etiologies of hydrocephalus in infants, which might relate to infection prophylaxis and high drainage resistance integrated in the shunt system. PMID- 29582172 TI - Gender differences in the presentation of dysphonia related to laryngopharyngeal reflux disease: a case-control study. AB - OBJECTIVE: To investigate the voice quality impairments in patients with laryngopharyngeal reflux (LPR) according to the gender. DESIGN: Controlled multi center study. MATERIALS AND METHODS: 80 LPR patients (40 males and 40 females) with reflux finding score (RFS) > 7 and reflux symptom index (RSI) > 13 were included and clinically compared according to gender. To be considered as LPR patients, subjects responded to an empiric therapeutic trial based on pantoprazole intake and diet recommendations for 3 months or had positive pH/Impedance metry. Voice Handicap Index (VHI); Short Form Healthy Survey 36 (SF36), blinded Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI); aerodynamic and acoustic measurements were assessed in all patients and compared with 80 healthy controls (40 males and 40 females) according to gender. RESULTS: The most common reasons for the consultation were, respectively, globus sensation in males (22.5%) and dysphonia (27.5%) in female who complained more of breathing difficulties and choking episodes related to LPR than males (p = 0.024). From a quality of life standpoint, female had increased significant impact of LPR disease on vitality and mental health than male. Compared to healthy subjects, both LPR male and female patients had stronger values of G, R, B, S, I, VHI, percent jitter, percent shimmer, and soft palate index than controls. In addition, LPR female had stronger values of lowest fundamental frequency and all aerodynamic measurements than controls. CONCLUSION: As showed in many other laryngeal conditions, voice quality of female could be more impaired by LPR than male. Some anatomical, histological and functional factors can be suspected and need additional future researches. PMID- 29582173 TI - Expression of hormone receptors in oropharyngeal squamous cell carcinoma. AB - OBJECTIVES: Hormone receptors play an important role in many types of cancers. Alongside factors associated with human papillomavirus (HPV) infection, hormonal receptors may impact the tumorigenesis of oropharyngeal cancer. MATERIALS AND METHODS: This study consists of 199 consecutive oropharyngeal squamous cell carcinoma (OPSCC) patients diagnosed and treated with a curative intent. We examined androgen (AR), estrogen (ER; both alpha and beta), and progesterone receptor (PR) expressions using immunohistochemistry comparing tumor and patient characteristics. RESULTS: AR was expressed in 16%, PR in 27% and ER-beta in 63% of the tumors. HPV- and p16-positive tumors expressed more AR and less PR than their negative counterparts. High PR expression was associated with poor disease specific and locoregional recurrence-free survival. CONCLUSION: AR, PR, and ER beta are expressed in OPSCC, and AR and PR expressions are associated with HPV and p16 status. Furthermore, PR appears to have prognostic significance. This may allow us to investigate the role of anti-hormone receptors in the treatment of OPSCC. PMID- 29582174 TI - Arterial spin labeling perfusion-weighted MR imaging: correlation of tumor blood flow with pathological degree of tumor differentiation, clinical stage and nodal metastasis of head and neck squamous cell carcinoma. AB - PURPOSE: The prognostic parameters of head and neck squamous cell carcinoma (HNSCC) include the pathological degree of tumor differentiation, clinical staging, and presence of metastatic cervical lymph nodes. To correlate tumor blood flow (TBF) acquired from arterial spin labeling (ASL) perfusion-weighted MR imaging with pathological degree of tumor differentiation, clinical stage, and nodal metastasis of HNSCC. MATERIALS AND METHODS: Retrospective analysis of 43 patients (31 male, 12 female with a mean age of 65 years) with HNSCC that underwent ASL of head and neck and TBF of HNSCC was calculated. Tumor staging and metastatic lymph nodes were determined. The stages of HNSCC were stage 1 (n = 7), stage II (n = 12), stage III (n = 11) and stage IV (n = 13). Metastatic cervical lymph nodes were seen in 24 patients. The degree of tumor differentiation was determined through pathological examination. RESULTS: The mean TBF of poorly and undifferentiated HNSCC (157.4 +/- 6.7 mL/100 g/min) was significantly different (P = 0.001) than that of well-to-moderately differentiated (142.5 +/- 5.7 mL/100 g/min) HNSCC. The cut-off TBF used to differentiate well-moderately differentiated from poorly and undifferentiated HNSCC was 152 mL/100 g/min with an area under the curve of 0.658 and accuracy of 88.4%. The mean TBF of stages I, II (146.10 +/- 9.1 mL/100 g/min) was significantly different (P = 0.014) than that of stages III, IV (153.33 +/- 9.3 mL/100 g/min) HNSCC. The cut-off TBF used to differentiate stages I, II from stages III and IV was 148 mL/100 g/min with an area under the curve of 0.701 and accuracy of 69.8%. The TBF was higher in patients with metastatic cervical lymph nodes. The cut-off TBF suspect metastatic node was 147 mL/100 g/min with an area under the curve of 0.671 and accuracy of 67.4%. CONCLUSION: TBF is a non-invasive imaging parameter that well correlated with pathological degree of tumor differentiation, clinical stage of tumor and nodal metastasis of HNSCC.

AB - We report a case of a 20-year-old male patient suffering from motorcycle accident complicated by rapid development of severe refractory hypoxemia and hypercapnia due to serious bilateral lung contusions and lacerations. Positive pressure mechanical ventilation induced pressure-dependent massive air leak from disrupted pulmonary tissue. Simultaneous implementation of veno-venous extracorporeal membrane oxygenation together with surfactant application allowed prolonged disconnection of patient from mechanical ventilation ("total lung rest" mode). Despite considerable areas of nonaerated tissue on computed tomography prior to the disconnection from mechanical ventilation, almost total functional recovery of lungs was eventually achieved. PMID- 29582176 TI - Hypoglycemia Prevention by Algorithm Design During Intravenous Insulin Infusion. AB - PURPOSE OF REVIEW: This review examines algorithm design features that may reduce risk for hypoglycemia while preserving glycemic control during intravenous insulin infusion. We focus principally upon algorithms in which the assignment of the insulin infusion rate (IR) depends upon maintenance rate of insulin infusion (MR) or a multiplier. RECENT FINDINGS: Design features that may mitigate risk for hypoglycemia include use of a mid-protocol bolus feature and establishment of a low BG threshold for temporary interruption of infusion. Computer-guided dosing may improve target attainment without exacerbating risk for hypoglycemia. Column assignment (MR) within a tabular user-interpreted algorithm or multiplier may be specified initially according to patient characteristics and medical condition with revision during treatment based on patient response. We hypothesize that a strictly increasing sigmoidal relationship between MR-dependent IR and BG may reduce risk for hypoglycemia, in comparison to a linear relationship between multiplier-dependent IR and BG. Guidelines are needed that curb excessive up titration of MR and recommend periodic pre-emptive trials of MR reduction. Future research should foster development of recommendations for "protocol maxima" of IR appropriate to patient condition. PMID- 29582177 TI - Association between two SCN1A polymorphisms and resistance to sodium channel blocking AEDs: a meta-analysis. AB - Sodium channel blocking antiepileptic drugs (SCB-AEDs) are common effective medications available for epilepsy. However, not all patients respond to this regimen and drug resistance is frequently encountered. Rs2298771(c.3184A > G/p.Thr1067Ala) and rs3812718(IVS5N +5G > A) polymorphisms are two of the most common polymorphisms in the SCN1A gene, which is closely related to resistance to SCB-AEDs. Therefore, we have conducted a meta-analysis to investigate the contribution of the two polymorphisms to resistance of SCB-AEDs. The PubMed, Embase, MEDLINE, and Cochrane Library databases were searched up to September 2017, for studies on the association of SCN1A polymorphisms with resistance to SCB-AEDs. A fixed-effects or random-effects model was used to calculate the pooled odds ratios based on the results from the heterogeneity tests. A total of eight studies were eligible for the pooled analysis, of which eight studies included SCN1A rs3812718 polymorphism and four studies included SCN1A rs2298771 polymorphism. The results showed that SCN1A rs2298771 polymorphism was significantly associated with resistance to SCB-AEDs. (A vs. G: OR = 0.76, 95% CI 0.61-0.95, P = 0.02; AA vs. AG + GG: OR = 0.71, 95% CI 0.54-0.94, P = 0.022). However, no association was observed between SCN1A rs3812718 polymorphism and resistance to SCB-AEDs. Our results indicate that the A-allele of SCN1A rs2298771 polymorphism, especially AA genotype, may play an important role in responsiveness to SCB-AEDs, while SCN1A rs3812718 polymorphism is not associated with SCB-AEDs.

PMID- 29582180 TI - Pain assessment with the revised nociception coma scale and outcomes of patients with unresponsive wakefulness syndrome: results from a pilot study. AB - The aim of this study was to evaluate whether standardized responses to nociceptive pain, assessed with the revised Nociception Coma Scale (NCS-R), were correlated with the outcomes of patients with unresponsive wakefulness syndrome (UWS) 6 months after admission to a rehabilitation department. We recruited 24 consecutive patients with UWS. Patients' consciousness levels were assessed with the revised Coma Recovery Scale (CRS-R) at admission and 6 months later, and their CRS-R scores were correlated with the NCS-R scores at admission. Ten of the 24 patients with UWS recovered consciousness after 6 months. The NCS-R score at admission was correlated with the CRS-R score at admission (P = 0.02), but not after 6 months (P = 0.6). Patients with and without consciousness improvement after 6 months showed no significant difference in the NCS-R total score and sub scores at admission (P values > 0.05). In conclusion, the correlation between NCS R and CRS-R scores at admission suggests that the standardized assessment of pain parallels patients' levels of consciousness, and may be helpful in the clinical evaluation of patients with UWS. Pain response assessed with the NCS-R was not related to the 6-month outcomes of patients with UWS. PMID- 29582181 TI - Self-Myofascial Vibro-Shearing: a Randomized Controlled Trial of Biomechanical and Related Changes in Male Breakdancers. AB - BACKGROUND: This randomized controlled trial explored the practicality and effectiveness of a novel tool-assisted self-help device, one that combines vibrational oscillation, leverage, and the shearing effect from the edges, for promoting meaningful changes in key biochemical tissue indices and related parameters. METHODS: One hundred and thirteen male breakdancers were randomized to an intervention or control group. Individuals assigned to the intervention group performed the self-help treatment on the quadriceps and the iliotibial band of their right thighs for 8 min, while individuals assigned to the control condition merely sat quietly during this period. Various primary outcome measures (e.g., elasticity, stiffness, range of motion, pain pressure threshold sensitization, and blood flow) were assessed before and after the intervention for each participant, with position and posture being standardized throughout. Subjective sensations and a measure selected to assess for potential experimental demand effects, serving as secondary measures, were also administered pre- to post-treatment. RESULTS: Stiffness was significantly reduced for both structures (p < 0.001), elasticity and flexibility of the quadriceps were increased significantly (p < 0.001 for each), sensitization was significantly lessened (p < 0.001), and local temperatures increased to a significant degree as well (p < 0.001) when comparing change scores following application of the self-help tool on the treated thighs to those on the untreated thighs. Participants using the self-help tool reported their treated leg as being more relaxed, light, and stable. CONCLUSIONS: The vibro-shearing manipulation with a muscle-fascia tool resulted in significant improvements in various objective mechanical tissue properties, range of motion, and pain desensitization in healthy, well conditioned dancers. These promising effects for a new tool-assisted self treatment indicate further basic investigations are warranted, as are pilot investigations with patient populations. PMID- 29582182 TI - Diagnosis and Management of Fecal Incontinence. AB - PURPOSE OF REVIEW: The purpose of this review is to highlight current and newer therapeutic approaches to treat fecal incontinence in patients who do not respond to conservative measures. RECENT FINDINGS: Neurostimulation techniques, injection of bulking agents, and radiofrequency energy delivery to the anal canal have been proposed and tested for fecal incontinence over the last decade. Sacral stimulation is both effective and durable and is now the most popular of the invasive techniques whereas percutaneous tibial stimulation, radiofrequency energy, and bulking agents are either less effective or their evaluation has been handicapped by suboptimal study designs. The precise indications for the new vaginal control device and anal plugs remain to be established. The magnetic anal sphincter is disappointing. Stem cell therapy is a potentially exciting approach, which is in its infancy. There continues to be an unmet need for innovative approaches to patients with fecal incontinence who do not respond to conservative measures. The efficacy of current and future therapies should be assessed using criteria more stringent than has been used in the past to provide a more realistic assessment of meaningful efficacy. PMID- 29582183 TI - Phenylbutazone (Bute, PBZ, EPZ): one drug across two species. AB - In this article we explore the different trajectories of this one drug, phenylbutazone, across two species, humans and horses in the period 1950-2000. The essay begins by following the introduction of the drug into human medicine in the early 1950s. It promised to be a less costly alternative to cortisone, one of the "wonder drugs" of the era, in the treatment of rheumatic conditions. Both drugs appeared to offer symptomatic relief rather than a cure, and did so with the risk of side effects, which with phenylbutazone were potentially so severe that it was eventually banned from human use, for all but a few diseases, in the early 1980s. Phenylbutazone had been used with other animals for many years without the same issues, but in the 1980s its uses in veterinary medicine, especially in horses, came under increased scrutiny, but for quite different reasons. The focus was primarily the equity, economics, and ethics of competition in equine sports, with differences in cross-species biology and medicine playing a secondary role. The story of phenylbutazone, a single drug, shows how the different biologies and social roles of its human/animal subjects resulted in very different and changing uses. While the drug had a seemingly common impact on pain and inflammation, there were inter-species differences in the drug's metabolism, the conditions treated, dosages, and, crucially, in intended clinical outcomes and perceptions of its benefits and risks. PMID- 29582184 TI - Small Bowel Amyloidosis. AB - PURPOSE OF REVIEW: The goal of this paper is to review the literature on small bowel amyloidosis. Our review focuses on the underlying etiology, histopathology, clinical features, endoscopic and radiologic findings, and the mainstay of management. RECENT FINDINGS: The latest research shows changing epidemiological trends of different types of amyloidosis. It also reveals a better understanding of its pathophysiology and shows improvement in treatment outcomes. Amyloidosis is a group of diseases of multiple etiologies and clinical presentations. It is characterized by pathological deposition of insoluble fibrillar proteins within various organs leading to disruption of their structure and function. The classification of amyloidosis includes primary, secondary, dialysis-related, senile, and hereditary. Amyloidosis can be systemic or localized. The incidence of AA amyloidosis is declining in frequency. If the gastrointestinal (GI) tract is involved, the small intestine is the most commonly affected site. Overall, outcomes among patients with newly diagnosed amyloidosis have improved. This article focuses on small bowel amyloidosis. PMID- 29582186 TI - Decision modelling of non-pharmacological interventions for individuals with dementia: a systematic review of methodologies. AB - OBJECTIVES: The main objective of this study is to conduct a systematic review to identify and discuss methodological issues surrounding decision modelling for economic evaluation of non-pharmacological interventions (NPIs) in dementia. METHODS: A systematic search was conducted for publications using decision modelling to investigate the cost-effectiveness of NPIs for individuals with dementia. Search was limited to studies in English. Studies were excluded if they evaluated interventions aimed only at caregivers of patients with dementia, or if they only included economic evaluation alongside an RCT without additional modelling. RESULTS: Two primary, five secondary and three tertiary prevention intervention studies were identified and reviewed. Five studies utilised Markov models, with others using discrete event, regression-based simulation, and decision tree approaches. A number of challenging methodological issues were identified, including the use of MMSE-score as the main outcome measure, limited number of strategies compared, restricted time horizons, and limited or dated data on dementia onset, progression and mortality. Only one of the three tertiary prevention studies explicitly considered the effectiveness of pharmacological therapies alongside their intervention. CONCLUSIONS: Economic evaluations of NPIs in dementia should utilise purposefully-developed decision models, and avoid models for evaluation of pharmaceuticals. Broader outcome measures could be a way to capture the wide impact of NPIs for dementia in future decision models. It is also important to account for the effects of pharmacological therapies alongside the NPIs in economic evaluations. Access to more localised and up-to-date data on dementia onset, progression and mortality is a priority for accurate prediction. PMID- 29582185 TI - Neuromodulation for Chronic Pelvic Pain. AB - PURPOSE OF REVIEW: Chronic pelvic pain is a heterogeneous condition that often requires multiple physician visits and various treatments prior to achieving an acceptable management strategy. Neuromodulation has been used to treat chronic pelvic pain that has failed other therapies. RECENT FINDINGS: Numerous modalities of neuromodulation have been used to alleviate chronic pelvic pain with promising results. Numerous modalities of neuromodulation have demonstrated efficacy in the management of pelvic pain. Further investigation is needed to elucidate the most effective treatment modality and to identify the patients who would benefit most from this therapy. PMID- 29582187 TI - Cultural Aspects in Symptomatology, Assessment, and Treatment of Personality Disorders. AB - PURPOSE OF REVIEW: This review discusses cultural trends, challenges, and approaches to assessment and treatment of personality traits and disorders. Specific focus include current developments in the Asian, Italian, Iranian, and Australian societies, as well as the process of acculturation, following moves between cultures with the impact on healthy and disordered personality function. RECENT FINDINGS: Each culture with its specific history, dimensions, values, and practices influences and gears the individual and family or group in unique ways that affect personality functioning. Similarly, each culture provides means of protection and assimilation as well as norms for acceptance and denunciations of specific behaviors and personality traits. The diagnosis of personality disorders and their treatment need to take into consideration the individual in the context of the culture and society in which they live. Core personality problems, especially emotion dysregulation and interpersonal functioning are specifically influenced by cultural norms and context. PMID- 29582188 TI - Immune-Mediated Necrotizing Myopathy. AB - PURPOSE OF REVIEW: Immune-mediated necrotizing myopathy (IMNM) is a type of autoimmune myopathy characterized by relatively severe proximal weakness, myofiber necrosis with minimal inflammatory cell infiltrate on muscle biopsy, and infrequent extra-muscular involvement. Here, we will review the characteristics of patients with IMNM. RECENT FINDINGS: Anti-signal recognition particle (SRP) and anti-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) autoantibodies are closely associated with IMNM and define unique subtypes of patients. Importantly, the new European Neuromuscular Centre criteria recognize anti-SRP myopathy, anti HMGCR myopathy, and autoantibody-negative IMNM as three distinct subtypes of IMNM. Anti-SRP myopathy patients have more severe muscle involvement, have more common extra-muscular features, and may respond best to immunosuppressive regimens that include rituximab. In contrast, anti-HMGCR myopathy is often associated with statin exposure and intravenous immunoglobulin treatment may be an effective treatment, even as monotherapy. Both anti-SRP and anti-HMGCR myopathy tend to be most severe in younger patients. Furthermore, children with these forms of IMNM may present with dystrophy-like features which are potentially reversible with immunosuppressant treatment. IMNM patients with either autoantibody may experience fatty replacement of muscle soon after disease onset, suggesting that intense and early immunosuppressant therapy may provide the best chance to avoid long-term disability. IMNM is composed of anti-SRP myopathy, anti-HMGCR myopathy, and autoantibody-negative IMNM. Both anti-SRP and anti-HMGCR myopathy can cause severe weakness, especially in younger patients. Anti-SRP myopathy patients tend to have the most severe weakness and most prevalent extra-muscular features. Autoantibody-negative IMNM remains poorly described. PMID- 29582189 TI - Mesenchymal Chondrosarcoma: a Review with Emphasis on its Fusion-Driven Biology. AB - Mesenchymal chondrosarcoma is a rare but deadly form of chondrosarcoma that typically affects adolescents and young adults. While curative intent is possible for patients with localized disease, few options exist for patients in the unresectable/metastatic setting. Thus, it is imperative to understand the fusion driven biology of this rare malignant neoplasm so as to lead to the future development of better therapeutics for this disease. This manuscript will briefly review the clinical and pathologic features of mesenchymal chondrosarcoma followed by an appraisal of existing data linked to the fusions, HEY1-NCOA2 and IRF2BP2-CDX1, and the associated downstream pathways. PMID- 29582190 TI - Evaluation of efficacy of infliximab for retinal vasculitis and extraocular symptoms in Behcet disease. AB - PURPOSE: We evaluated ocular symptoms and activity of retinal vasculitis of Behcet disease before and after infliximab therapy, using Behcet disease ocular attack score 24 (BOS24) and fluorescein angiography (FA) score. We also analyzed the efficacy of infliximab for ocular and extraocular symptoms. STUDY DESIGN: Retrospective study. SUBJECT AND METHODS: Using medical records, we analyzed FA and BOS24 to evaluate the association between the efficacy of infliximab therapy and FA as well as BOS24 scores. Further, we evaluated the association between FA scores and extraocular symptoms. RESULTS: After 2 years of infliximab therapy, 6 month BOS24 was significantly reduced compared to that before treatment (PreBOS24 6M). After 4 years of infliximab therapy, 6-month BOS24 was also significantly reduced compared to preBOS24-6M. After 2 years of infliximab therapy, FA score median (interquartile range) decreased significantly compared to that before treatment [FA-2Y vs. preFA: 0 (0-0) vs.15.5 (12-24); P < 0.0001; n = 38]. The FA 4Y score in subjects followed for at least 4 years was also significantly lower than the preFA score [0 (0-0) vs.16.5 (12-24.5); P < 0.0001; n = 28]. Among 38 patients, extraocular symptoms were resolved following treatment in 29 cases (76.3%). No significant correlation was observed between the improvement in FA-2Y and FA-4Y scores and the occurrence and persistence of extraocular symptoms (P = 0.33; n = 38 or P = 0.4; n = 28). CONCLUSION: Infliximab therapy is effective for the treatment of ocular and extraocular involvement of Behcet disease. BOS24 and FA scores are useful for evaluating the efficacy of infliximab therapy. PMID- 29582191 TI - Zirconia stimulates ECM-remodeling as a prerequisite to pre-osteoblast adhesion/proliferation by possible interference with cellular anchorage. AB - The biological response to zirconia (ZrO2) is not completely understood, which prompted us to address its effect on pre-osteoblastic cells in both direct and indirect manner. Our results showed that zirconia triggers important intracellular signaling mainly by governing survival signals which leads to cell adhesion and proliferation by modulating signaling cascade responsible for dynamic cytoskeleton rearrangement, as observed by fluorescence microscopy. The phosphorylations of Focal Adhesion Kinase (FAK) and Rac1 decreased in response to ZrO2 enriched medium. This corroborates the result of the crystal violet assay, which indicated a significant decrease of pre-osteoblast adhesion in responding to ZrO2 enriched medium. However, we credit this decrease on pre-osteoblast adhesion to the need to govern intracellular repertory of intracellular pathways involved with cell cycle progression, because we found a significant up phosphorylation of Mitogen-Activated Protein Kinase (MAPK)-p38 and Cyclin dependent kinase 2 (CDK2), while p15 (a cell cycle suppressor) decreased. Importantly, Protein phosphatase 2 A (PP2A) activity decreased, guaranteeing the significant up-phosphorylation of MAPK -p38 in response to ZrO2 enriched medium. Complementarily, there was a regulation of Matrix Metalloproteinases (MMPs) in response to Zirconia and this remodeling could affect cell phenotype by interfering on cell anchorage. Altogether, our results show a repertory of signaling molecules, which suggests that ECM remodel as a pre-requisite to pre osteoblast phenotype by affecting their anchoring in responding to zirconia. PMID- 29582192 TI - Prevalence and Risk of Polypharmacy Among Elderly Cancer Patients Receiving Chemotherapy in Ambulatory Oncology Setting. AB - PURPOSE OF REVIEW: This was a single center, retrospective cross-sectional study looking into the incidence and types of drug-related problems (DRPs) detected among elderly cancer patients receiving at least three long-term medications concurrent with IV chemotherapy, and the types of intervention taken to address these DRPs. This paper serves to elucidate the prevalence and risk of polypharmacy in our geriatric oncology population in an ambulatory care setting, to raise awareness on this growing issue and to encourage more resource allocation to address this healthcare phenomenon. RECENT FINDINGS: DRP was detected in 77.6% of elderly cancer patients receiving at least three long-term medications concurrent with IV chemotherapy, with an average incidence of three DRPs per patient. Approximately half of DRPs were related to long-term medications. Forty percent of DRPs required interventions at the prescriber level. The use of five or more medications was shown to almost double the risk of DRP occurrence (OR 1.862, P = 0.039). Out of the eight predefined categories of DRPs, underprescribing was the most common (26.7%), followed by adverse drug reaction (25.0%) and drug non-adherence (16.2%). Polypharmacy leading to DRPs is a common occurrence in elderly cancer patients receiving outpatient IV chemotherapy. There should be systematic measures in place to identify patients who are at greater risk of inappropriate polypharmacy and DRPs, and hence more frequent drug therapy optimization and monitoring. The identification of DRPs is an important step to circumvent serious drug-related harm. Future healthcare interventions directed at reducing DRPs should aim to assess the clinical and economic impact of such interventions. PMID- 29582193 TI - Streptomyces urticae sp. nov., isolated from rhizosphere soil of Urtica urens L. AB - Two novel Gram-stain positive, spore-forming, aerobic actinomycetes, designated NEAU-PCY-1T and NEAU-PCY-2, were isolated from rhizosphere soil of Urtica urens L. collected from Anshan, Liaoning Province, northeast China. The 16S rRNA gene sequence analysis showed that strains NEAU-PCY-1T and NEAU-PCY-2 exhibited 99.8% similarity with each other and are closely related to Streptomyces abietis DSM 42080T (98.2, 98.3%) and Streptomyces fildesensis DSM 41987T (98.0, 98.1%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains formed a cluster with these two closely related species. Moreover, DNA DNA hybridization results and some phenotypic, physiological and biochemical properties differentiated the two strains from their close relatives in the genus Streptomyces. Based on a polyphasic taxonomy study, strains NEAU-PCY-1T and NEAU PCY-2 are considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces urticae sp. nov. is proposed, with NEAU-PCY-1T (= DSM 105115T = CCTCC AA 2017015T) as the type strain. PMID- 29582194 TI - Clinical Practice Guidelines for Fertility Preservation in Pediatric, Adolescent, and Young Adults with Cancer. AB - In recent years, more cancer patients are achieving long-term survival owing to advances in treatment. However, cancer treatment can cause gonadal dysfunction that leads to loss of fertility. Thus, it is important for clinical oncologists to consider fertility preservation in children, adolescents, and young adults with cancer who are expected to have a favorable outcome and may wish to have children in the future. Sometimes, fertility preservation has to be abandoned depending on the stage of the cancer and the general condition of the patient, because fertility preservation procedures may unacceptably delay cancer treatment or be too risky for the patient. The Clinical Practice Guidelines for Fertility Preservation in Children, Adolescents, and Young Adults with Cancer were published in 2017 as the first guidelines for this field in Japan. These guidelines cover general principles and recommendations for 8 oncological categories, which is a point of difference from other guidelines. Close coordination between clinical oncologists and reproductive medicine specialists is important over the long term from the pretreatment phase through the post treatment phase. Therefore, the guidelines were devised to help medical staff consider the available fertility preservation therapies and determine whether performing fertility preservation is appropriate before initiating the treatment for cancer, and to ultimately improve survivorship for children, adolescents, and young adults with cancer. This article reviews the latest information concerning clinical practice guidelines around the world, including the American Society of Clinical Oncology guidelines that were the first to be published in this field. PMID- 29582195 TI - Patterns of Family and Intimate Partner Violence in Problem Gamblers. AB - While the evidence about the statistical co-occurrence of family violence and problem gambling is growing, the mechanism by which the two behaviours are related is less clear. This study sought to clarify the dynamics of the problem behaviours, including the role of gender in victimisation and perpetration of violence in the family. Two-hundred-and-twelve treatment seeking problem gamblers (50.5% females) were recruited for interviews about past year FV and IPV experiences. The interviews included questions about the types of FV and IPV using the HITS tool (Sherin et al. in Fam Med Kans City 30:508-512, 1998). The questions addressed multiple family members, the temporal order of violence and gambling and the perceived associations between the two behaviours. The result show that well over half (60.8%; 95 CI = 54.1-67.2) of the participants reported some form of violence in the past 12 months, with no gender differences in relation to perpetration and victimisation. Bidirectional violence (43.9%; 95 CI = 37.4-50.6) was significantly more common than 'perpetration only' (11.3%; 95 CI = 7.7-16.3) or 'victimisation only' (5.7%; 95 CI = 3.3-9.6). Violence was mostly verbal, although considerable rates of physical violence also featured in the responses. 'Participants' own gambling preceded violence in a majority of the interviews but a small group of IPV victims reported that being a victim had led to their problematic gambling. These results can be used inform prevention, better treatment matching and capacity building in family violence and problem gambling services, where a significant focus should be on situational IPV. PMID- 29582196 TI - Pregnancy Outcomes Following Exposure to Quinolone Antibiotics - a Systematic Review and Meta-Analysis. AB - PURPOSE: Quinolones, and the fluoroquinolones subgroup, are a class of antibiotics commonly used for the treatment of a wide variety of infections. However, their safety profile in pregnant women is controversial. The association between fluoroquinolones and arthropathy was primarily described in immature animals, and only rarely in humans, yet it has led to the restricted use of quinolones during pregnancy. We aimed to assess their safety during pregnancy. METHODS: A systematic review and meta-analysis assessing the safety of quinolone exposure during any time of pregnancy, and during first trimester alone, was performed. The systematic review was performed using MEDLINE and EMBASE, and followed the PRISMA guidelines. Pooled effect sizes with corresponding 95% confidence intervals (CI) were calculated using random effects models, comparing fetal outcomes of quinolone exposed and non-exposed pregnancies. Only cohort and case control studies were included in the meta-analysis. RESULT: Twelve studies met the inclusion criteria. Exposure to quinolones during first trimester was not associated with an increased risk for birth defects (pooled odds ratio (OR) = 0.89, 95% CI 0.72-1.09, I2 = 0%), stillbirth (OR = 1.32, 95% CI 0.33-5.34, I2 = 16%), preterm birth (OR = 1.10, 95% CI 0.83-1.48, I2 = 41%) and low birth weight (OR = 1.29, 95% CI 0.54-3.12, I2 = 67%). CONCLUSION: The use of quinolones during the first-trimester of pregnancy was not associated with an increased risk of birth defects, stillbirths, preterm births or low birth weight. STUDY REGISTRY: PROSPERO CRD42017060573. PMID- 29582197 TI - Reduce the Sensitivity of CL-20 by Improving Thermal Conductivity Through Carbon Nanomaterials. AB - The graphene (rGO) and carbon nanotube (CNT) were adopted to enhance the thermal conductivity of CL-20-based composites as conductive fillers. The microstructure features were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD), and tested the properties by differential scanning calorimeter (DSC), static electricity accumulation, special height, thermal conductivity, and detonation velocity. The results showed that the mixture of rGO and CNT had better effect in thermal conductivity than rGO or CNT alone under the same loading (1 wt%) and it formed a three-dimensional heat-conducting network structure to improve the heat property of the system. Besides, the linear fit proved that the thermal conductivity of the CL-20-based composites were negatively correlated with the impact sensitivity, which also explained that the impact sensitivity was significantly reduced after the thermal conductivity increased and the explosive still maintained better energy. PMID- 29582198 TI - Molecular dynamics simulations of inverse patchy colloids. AB - Inverse patchy colloids are patchy particles with differently charged surface regions. In this paper we focus on inverse patchy colloids with two different polar patches and an oppositely charged equatorial belt, and we describe a model and a reliable and efficient numerical algorithm that can be applied to investigate the properties of these particles in molecular dynamics simulations. PMID- 29582199 TI - Integrated Bio-behavioral Approach to Improve Adherence to Pre-exposure Prophylaxis and Reduce HIV Risk in People Who Use Drugs: A Pilot Feasibility Study. AB - This study reports the feasibility, acceptability, and preliminary efficacy of the bio-behavioral community-friendly health recovery program-an integrated, HIV prevention intervention to improve pre-exposure prophylaxis (PrEP) adherence and HIV-risk reduction behaviors among high-risk people who use drugs. We used a within-subjects, pretest-posttest follow-up design to recruit participants, who were HIV-uninfected, methadone-maintained and reported HIV-risk behaviors and had initiated PrEP (n = 40; males: 55%). Participants were assessed at baseline (T0), immediately post-intervention (4 weeks: T4) and 4 weeks post-intervention (T8). Immediately after completing the four weekly intervention groups, participants underwent a post-intervention assessment including in-depth qualitative interviews. Feasibility was high, assessed by participant willingness to enroll (90.1%) and retention (95%). Results showed that participants were highly satisfied and perceived the intervention as valuable and acceptable [mean: 81.3 (range 0-100)]. Significant enhancements in self-reported PrEP adherence [F(2,74) = 7.500, p = 0.001] and PrEP-related knowledge [F(2,74) = 3.828, p = 0.026] were observed. Drug-related (e.g., injection of drugs, sharing of injection equipment) and sex-related (e.g., number of sexual partners, condomless sex) risk behaviors were reduced, while information, motivation, and behavioral skills (IMB) constructs increased. The results support feasibility and high acceptability and support further examination of the efficacy of this combination bio-behavioral intervention in a prospective clinical trial.

AB - Adiponectin is a key molecule whose upregulation may ameliorate symptoms of type 2 diabetes mellitus and disorders of lipid metabolism. Several plant-derived components have been shown to enhance adiponectin secretion; however, there have been no reports on the effects of animal-derived products. Therefore, in the current study, we investigated whether hot-water extracts of specific livestock by-products induce the expression of adiponectin in mouse 3T3-L1 adipocytes. Out of the 11 extracts tested, pig testis extract (PTE) was found to enhance adiponectin expression and secretion by 3T3-L1 cells. Furthermore, simultaneous treatment with PTE and daidzein, a soy phytoestrogen, synergistically enhanced adiponectin secretion. Moreover, pretreatment with an estrogen receptor beta antagonist (PHTPP) diminished adiponectin secretion from daidzein-treated cells but not from PTE-treated cells. Transcriptome analyses revealed that both daidzein and PTE regulate the peroxisome proliferator-activated receptor signaling pathway, although differences in the regulation of gene expression were observed between PTE- and daidzein-treated cells. These results suggest that PTE ameliorates lipid metabolic dysfunction by promoting adipocyte differentiation and enhancing adiponectin secretion via a mechanism different from that of daidzein. PMID- 29582201 TI - Friedelane, isolated from Pouzolzia indica Gaud. exhibits toxic effect against melanoma. AB - Melanoma is a predominant cause of skin cancer-related deaths. It was reported that, the methanolic extract of Pouzolzia Indica (P. indica) on chromatography gave five compounds (1-hentriacontanyl palmitate, myricyl alcohol, 6,7 dimethoxycoumarin, trichadonic acid and friedelane), which inhibited the acute promyelocytic leukemia cell lines, NB4, and HT93A. Friedelane was extracted as active compound from methanolic extract of P. indica. In this study, friedelane was tested on murine metastatic B16F10 and B16BL6 melanoma cell lines. To achieve the target, the cell viability using trypan blue exclusion, acridine orange/EtBr staining and cell cytotoxicity were tested using MTT assay. Caspase-3, caspase-9, Cyt-c, BAD and Bax protein were assayed to evidence the apoptosis induction. The compound friedelane shows potent cytotoxic effect against metastatic melanoma mouse cell lines in 10 ug/ml concentration. PMID- 29582202 TI - Automated quantitative image analysis for ex vivo metastasis assays reveals differing lung composition requirements for metastasis suppression by KISS1. AB - Imaging is broadly used in biomedical research, but signal variation complicates automated analysis. Using the Pulmonary Metastasis Assay (PuMA) to study metastatic colonization by the metastasis suppressor KISS1, we cultured GFP expressing melanoma cells in living mouse lung ex vivo for 3 weeks. Epifluorescence images of cells were used to measure growth, creating large datasets which were time consuming and challenging to quantify manually due to scattering of light from outside the focal plane. To address these challenges, we developed an automated workflow to standardize the measurement of disseminated cancer cell growth by applying statistical quality control to remove unanalyzable images followed and a filtering algorithm to quantify only in-focus cells. Using this tool, we demonstrate that expression of the metastasis suppressor KISS1 does not suppress growth of melanoma cells in the PuMA, in contrast to the robust suppression of lung metastasis observed in vivo. This result may suggest that a factor required for metastasis suppression is present in vivo but absent in the PuMA, or that KISS1 suppresses lung metastasis at a step in the metastatic cascade not tested by the PuMA. Together, these data provide a new tool for quantification of metastasis assays and further insight into the mechanism of KISS1 mediated metastasis suppression in the lung. PMID- 29582203 TI - Prevalence and Types of Anemia in a Large Refugee Cohort in Western Europe in 2015. AB - Currently, vast numbers of migrants with largely unknown health statuses have been entering Europe. To improve care taking strategies, prevalence, severity and types of anemia in a large refugee cohort were assessed. Blood counts were performed in n = 787 inhabitants from six German refugee centers. Most included migrants were young, male adults. Anemia was present in 22.5% of subjects with an age-dependent prevalence increase (7.9% > 18 years vs. 30.8% > 50 years). More females than males were anemic (27.1% vs. 20.4%). The majority of affected migrants had mild anemia (86.2%) of either normocytic/normochromic (55.9%) or microcytic/hypochromic (20.9%) type. Observed anemia frequencies are in accordance with global anemia prevalence recently estimated by the WHO. However, the observed high rates of anemia particularly in female and older refugees emphasize the need for adapted care taking strategies in refugee medicine. Further evaluation of causes of anemia in the migrating population is needed. PMID- 29582204 TI - GABAergic Mechanism of Anticonvulsive Effect of Chemical Agent RU-1205. AB - The study examined the effect of 9-(2-morpholinoethyl)-2-(4 fluorophenyl)imidazo[1,2-alpha] benzimidazole dihydrochloride (RU-1205) on the latency of seizures provoked by corazol, bicuculline, or picrotoxin. This agent (10 and 20 mg/kg) increased the seizure latency in the experimental models of epileptogenesis. The blockers of GABAA and GABA A -rho receptors picrotoxin and (1,2,5,6-tetrahydropyridin-4-yl)methylphosphinic acid, respectively, were employed to study the effects of RU-1205 on electrical activity of somatosensory cortical neurons and on formation of pathological rhythms in the rat brain. RU 1205 inhibited the focal background rhythm and eliminated the epileptiform activity, which can be mediated by interaction with GABAA receptors. PMID- 29582205 TI - In Vitro Model for Studying of the Role of IGFBP6 Gene in Breast Cancer Metastasizing. AB - IGFBP6 gene plays an important role in the pathogenesis of breast cancer. In this work, we performed knockdown of IGFBP6 gene in MDA-MB-231 cells and obtained a stable cell line. Knockdown of IGFBP6 gene was confirmed by the real-time PCR. The influence of IGFBP6 gene on migration and proliferation of breast cancer cells was studied. Knockdown of IGFBP6 gene reduced migration activity of MDA-MB 231 cells and increased their proliferation rate. This in vitro cell model can be used for the further analysis of the role of IGFBP6 gene in the pathogenesis of breast cancer. PMID- 29582206 TI - Parental and Child Psychopathology: Moderated Mediation by Gender and Parent Child Relationship Quality. AB - Previous literature has not examined the processes underlying the relations among parent-child relationship quality, parental psychopathology, and child psychopathology in the context of gender. Further, research examining these variables in emerging adulthood is lacking. The current study examined whether parent-child relationship quality would mediate the relation between parental and child psychopathology, and whether gender moderated these associations. Participants were emerging adults (N = 665) who reported on perceptions of their parents' and their own psychological problems as well as their parent-child relationship quality. Results indicated that the relation between parental internalizing problems and parent-child relationship quality was positive for males, and that mother-child relationship quality was related positively to psychological problems in males. This suggests that sons may grow closer to their parents (particularly their mother) who are exhibiting internalizing problems; in turn, this enmeshed relationship may facilitate transmission of psychopathology. Mediational paths were conditional upon gender, suggesting moderated mediation. Overall, the current study emphasizes that the complexities of parenting must be understood in the context of gender. Further, the mother-son dyad may particularly warrant further attention.

PMID- 29582209 TI - Long-term exposure to TNF-alpha leads human skin fibroblasts to a p38 MAPK- and ROS-mediated premature senescence. AB - Tumor necrosis factor alpha (TNF-alpha) is an inflammatory mediator overexpressed in the skin as a response to ultraviolet radiation, as well as in chronic non healing wounds. On the other hand, senescent fibroblasts have been shown to accumulate in the skin under these stressful conditions. Accordingly, here we assessed the putative implication of TNF-alpha in the induction of premature senescence of human adult dermal fibroblasts. We showed that TNF-alpha led to a rapid transient p38 MAPK activation, while elevation of reactive oxygen species (ROS) only occurred after a chronic exposure to TNF-alpha. Furthermore, in contrast to the majority of previous reports using various cell models and experimental settings, it was a long-term treatment with TNF-alpha that resulted in the premature senescence of human dermal fibroblasts, as shown by the reduced proliferative potential and the increased senescence associated beta galactosidase staining of the cells. TNF-alpha-senescent cells displayed a permanent phosphorylation of p38 MAPK and an inflammatory and catabolic phenotype. Increased ROS levels were also observed, possibly attributed to the weakened anti-oxidative response evidenced by the underexpression of the Nrf2 regulated genes encoding HO-1 and NQO1. These traits and the overall senescent phenotype were significantly reversed using the known anti-oxidant N-acetyl-L cysteine or a specific p38 MAPK inhibitor, suggesting the participation of oxidative stress and of the p38 MAPK pathway in TNF-alpha-triggered premature senescence. Even more, the observed blockade of ROS accumulation in senescent skin fibroblasts by p38 MAPK inhibition indicates a possible link between these two separate events during the manifestation of TNF-alpha-induced senescence. PMID- 29582208 TI - Update on Bile Acid Malabsorption: Finally Ready for Prime Time? AB - PURPOSE OF REVIEW: To provide an update on the prevalence, pathophysiology, disease associations, and treatment options for bile acid malabsorption (BAM). RECENT FINDINGS: *Molecular mechanisms-BAs prevent water reabsorption and increase water secretion by intracellular mediators, increasing aquaporin channels and intracellular permeability. *Inflammatory bowel disease-new molecular mechanisms of BAM are identified in patients without ileal disease, including changes in expression of ileal BA transporter and nuclear receptors involved in BA homeostasis. *Microscopic colitis-BAM is one of the mechanisms leading to microscopic colitis. *Diagnostic testing-new diagnostic tests have been launched in the USA (serum C4 and fecal 48-h BA excretion); stimulated FGF19 has higher detection of BAM compared to fasting sample alone. *Treatment investigational FXR agonists may provide a daily, oral option for treatment of BAM instead of BA sequestrants. There is a greater appreciation of the biological role of bile acids across multiple fields of medicine, including gastrointestinal indications. PMID- 29582210 TI - In-hospital and day-120 survival of critically ill solid cancer patients after discharge of the intensive care units: results of a retrospective multicenter study-A Groupe de recherche respiratoire en reanimation en Onco-Hematologie (Grrr OH) study. AB - OBJECTIVES: To assess outcomes at hospital discharge and day-120 after intensive care unit (ICU) discharge among patients with solid cancer admitted to ICU and to identify characteristics associated with in-hospital and day-120 after ICU discharge mortalities. DESIGN: International, multicenter, retrospective study. SETTING: Five ICUs in France and Brazil, two located in cancer centers, two in university affiliated and one in general hospitals. PATIENTS: Consecutive patients aged > 18 years, with underlying solid cancers (known before admission to the ICU or diagnosed during the stay in the ICU), admitted to the participating ICUs and discharged alive from the ICU from January 2006 to December 2011 were included in this study. Patients admitted after scheduled surgery or to secure procedure were excluded. Variables of interest were in hospital and day-120 post-ICU mortality among patients discharged alive from the ICU. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: A total of 1053 patients aged 63 years (54-71) (median [IQR]) were included. Most of the patients were of the male gender (66.8%). The in-ICU, in-hospital, and four-month post-ICU discharge mortalities were, respectively, 41.3, 60.7, and 65.8%. Among patients discharged alive from the ICU, in multivariate analysis, factors associated with four months post-ICU discharge mortality were type of cancer (OR from 0.25 to 0.52 when compared to lung cancers), systemic extension of the disease (OR 2.54; 95% CI 1.87-3.45), need for invasive mechanical ventilation (OR 2.54; 95% CI 1.80-3.59), for vasopressors (OR 2.35; 95% CI 1.66-3.29), or renal replacement therapy (OR 1.54; 95% CI 0.99-2.38). A predictive score, "Oncoscore," was built performing fairly in predicting 4 months post-ICU discharge outcome (AUC 0.74; 95% CI 0.71 0.77). CONCLUSION: Despite the high day-120 mortality following the ICU discharge, our study reports a meaningful medium-term survival rate after the ICU discharge of solid cancer patients. Of utmost importance, the "Oncoscore" must be validated in prospective studies and cannot be used, in its form without external validation, for individual decision making. Prospective studies to answer questions not provided by this study are needed, including only patients with solid cancers admitted in the ICU for medical reasons or after emergency surgery. PMID- 29582211 TI - The Caspase 1 Inhibitor VX-765 Protects the Isolated Rat Heart via the RISK Pathway. AB - PURPOSE: Protecting the heart from ischaemia-reperfusion (IR) injury is a major goal in patients presenting with an acute myocardial infarction. Pyroptosis is a novel form of cell death in which caspase 1 is activated and cleaves interleukin 1beta. VX-785 is a highly selective, prodrug caspase 1 inhibitor that is also clinically available. It has been shown to be protective against acute IR in vivo rat model, and therefore might be a promising possibility for future cardioprotective therapy. However, it is not known whether protection by VX-765 involves the reperfusion injury salvage kinase (RISK) pathway. We therefore investigated whether VX-765 protects the isolated, perfused rat heart via the PI3K/Akt pathway and whether protection was additive with ischaemic preconditioning (IPC). METHODS: Langendorff-perfused rat hearts were subject to ischaemia and reperfusion injury in the presence of 30 MUM VX-765, with precedent IPC, or the combination of VX-765 and IPC. RESULTS: VX-765 reduced infarct size (28 vs 48% control; P < 0.05) to a similar extent as IPC (30%; P < 0.05). The PI3 kinase inhibitor, wortmannin, abolished the protective effect of VX-765. Importantly in the model used, we were unable to show additive protection with VX 765 + IPC. CONCLUSIONS: The caspase 1 inhibitor, VX-765, was able to reduce myocardial infarction in a model of IR injury. However, the addition of IPC did not demonstrate any further protection. PMID- 29582212 TI - Evaluation of potential antiplatelet effects of CSL112 (Apolipoprotein A-I [Human]) in patients with atherosclerosis: results from a phase 2a study. AB - CSL112 (Apolipoprotein A-I [Human]), an infusible, plasma-derived apolipoprotein A-I, is being developed to reduce cardiovascular events following acute myocardial infarction (AMI). A predecessor compound (CSL111) demonstrated a potential antiplatelet effect. A phase 2a multicentre, randomised, single ascending dose study in patients with stable atherosclerotic disease receiving dual antiplatelet therapy (DAPT) assessed the potential additive effects of CSL112 administration on platelet function and increase bleeding risk in the subacute period after AMI. Patients (n = 44) on aspirin (75-325 mg/day) and either clopidogrel (75 mg/day, n = 37) or prasugrel (10 mg/day, n = 7) for > 30 days alongside standard-of-care therapy were randomised to a single dose of placebo or CSL112: 1.7, 3.4, or 6.8 g. Light transmission aggregometry was used to assess platelet aggregation in response to 2 mM arachidonic acid, 5 and 20 uM adenosine diphosphate, and 4 ug/mL collagen, pre-dose (baseline) and up to 48 h post-dosing. Compared to placebo, CSL112 had no clinically meaningful time- or dose-dependent effects on maximum platelet aggregation in response to any agonist, by either dose or renal function subgroup (p > 0.05). Coagulation parameters showed little variation over time or between treatment groups (p > 0.05). CSL112, when co-administered with standard DAPT, did not significantly influence platelet aggregation in response to agonists and is, therefore, not expected to significantly increase bleeding risk when administered with antiplatelet therapies. PMID- 29582213 TI - Management of antithrombotic therapy in adults with immune thrombocytopenia (ITP): a survey of ITP specialists and general hematologist-oncologists. AB - While patients with immune thrombocytopenia (ITP) and low platelet counts are at risk for bleeding, they are not protected against arterial and venous thrombotic events. Frequently, hematologists are asked to consult on a patient with ITP requiring an antiplatelet (AP) agent or anticoagulant (AC). No direct evidence exists to guide hematologists in weighing the risk of thrombosis against the risk of bleeding in patients with ITP. Therefore, we performed a survey to determine the preferred management of AP/AC therapy in ITP patients. The survey described hypothetical patient scenarios and asked respondents to recommend a minimum platelet count for initiation of AP/AC therapy. We surveyed both hematologists with an international reputation in treatment of ITP (n = 48) and also general hematologist-oncologists in Oklahoma (n = 97). Response rates were 38/48 (79%) for the ITP specialists and 46/97 (47%) for general hematologist-oncologists. Overall, recommended platelet thresholds for antithrombotic therapy were similar between ITP specialists and general hematologist-oncologists. Although both groups recommended a minimum platelet count of 50 * 109/L for AP and AC therapy in most scenarios, there was great variability in individual practice patterns among respondents. This study highlights the need for studies of patients with ITP who require AP/AC therapy to provide high-quality evidence for establishing optimal management strategies. PMID- 29582214 TI - The effect of gramicidin inclusions on the local order of membrane components. AB - We study the local effect of the antimicrobial peptide Gramicidin A on bilayers composed of lipids or surfactants using nuclear magnetic resonance spectroscopy and wide-angle X-ray scattering, techniques that probe the orientational and positional order of the alkyl chains, respectively. The two types of order vary with temperature and peptide concentration in complex ways which depend on the membrane composition, highlighting the subtlety of the interaction between inclusions and the host bilayer. The amplitude of the variation is relatively low, indicating that the macroscopic constants used to describe the elasticity of the bilayer are unlikely to change with the addition of peptide.

PMID- 29582216 TI - Commentary on Participation in Preventive Interventions. AB - In this commentary on the special issue, Preventive Parenting Interventions: Advancing Conceptualizations and Enhancing Reach, operationalization of participation, who engages in prevention interventions, and common themes from the studies are discussed. The papers in the special issue illustrate the importance of studying factors that increase participation in prevention and point out the need for additional research to understand these factors. These papers highlight the diverse conceptualizations of participation as well as a need to move toward standardization of methods to assess related constructs. Research is needed to elucidate the potential of enhanced participation and engagement in interventions to meaningfully impact intervention outcomes and ultimately improve the population-level benefit attributable to prevention efforts. Prevention scientists should attend to factors influencing participation in prevention as early in the intervention research process as possible in order to increase the likelihood that the target population will utilize evidence-based prevention interventions in real-world settings, under real-world conditions.

AB - Highly stretchable and electrically conductive thermoplastic polyurethane (TPU) nanofibrous composite based on electrospinning for flexible strain sensor and stretchable conductor has been fabricated via in situ polymerization of polyaniline (PANI) on TPU nanofibrous membrane. The PANI/TPU membrane-based sensor could detect a strain from 0 to 160% with fast response and excellent stability. Meanwhile, the TPU composite has good stability and durability. Besides, the composite could be adapted to various non-flat working environments and could maintain opportune conductivity at different operating temperatures. This work provides an easy operating and low-cost method to fabricate highly stretchable and electrically conductive nanofibrous membrane, which could be applied to detect quick and tiny human actions. PMID- 29582218 TI - Current Concepts in the Treatment of Resectable Pancreatic Cancer. AB - PURPOSE OF REVIEW: The diagnosis of pancreatic cancer carries with it a high mortality rate. Despite advances in the field, this has remained relatively unchanged over the last few decades. Current options for the treatment of resectable pancreatic ductal adenocarcinoma will be reviewed here in conjunction with the historical data that support them. We will focus on updates in treatment guidelines and ongoing clinical trials of interest. RECENT FINDINGS: For localized disease, standard of care includes resection followed by adjuvant chemotherapy +/- chemoradiation. Recently, a report was published supporting the use of doublet therapy with gemcitabine and capecitabine (as opposed to gemcitabine monotherapy), which prompted a practice-changing update to major treatment guidelines. Multiple trials using neoadjuvant treatment, novel therapies, and different forms of radiation are ongoing. Although pancreatic cancer is an active area of research, outcomes remain dismal. Clinical trials will need to be more robust and innovative to drastically improve survival statistics. PMID- 29582219 TI - Scientific output quality of 40 globally top-ranked medical researchers in the field of osteoporosis. AB - : The study presents the research output of 40 globally top-ranked authors, publishing in the field of osteoporosis. Their h-index is compared with the Scientific Quality Index (SQI), a novel indicator. Using SQI, 92.5% of the authors changed their initial positions in the general ranking. SQI partially depends on bibliometric measures different from those influencing h-index and may be considered as an assessment tool, reflecting more objective, qualitative, rather than quantitative, features of individual scientific output. PURPOSE: The study approaches the research output of 40 globally top-ranked authors in the field of osteoporosis. METHODS: The assessed authors were identified in the Scopus database, using the key word "osteoporosis" and the h-index data, collected during the last decade (2008-2017). The data, concerning the scientific output, expressed by the h-index, were compared with a novel indicator of scientific quality-called the Scientific Quality Index (SQI). SQI is calculated according to the following formula: Parameter No. 1 + Parameter No. 2, where: Parameter No. 1 (the percent of papers cited >= 10 times) the number of papers cited >= 10 times (excluding self-citations and citations of all co-authors) is divided by the number of all the published papers (including the papers with no citation) * 100%, Parameter No. 2 (the mean number of citations per paper) the total number of citations (excluding self-citations and citations of all co authors) divided by the number of all published papers (including papers with no citation). RESULTS: The following research output values were obtained: the citation index, 2483.6 +/- 1348.7; the total number of papers, 75.1 +/- 23.2; the total number of cited papers, 69.3 +/- 22.0; the number of papers cited, at least, 10 times, 45.4 +/- 17.2; the percent of papers cited, at least, 10 times, 59.9 +/- 10.0; and the mean citations per paper, 32.8 +/- 15.0. The mean value of Hirsch index was 24.2 +/- 6.2 and SQI 92.7 +/- 22.3. Using SQI, only three authors did not change their initial ranking position, established according to the h-index; 18 authors noted a decrease, while other 19 improved their initial ranking position. The h-index correlated with SQI; r = 0.72; p < 0.0001. CONCLUSION: Qualitative features of scientific output, reflected by SQI, have changed the classification of 92.5% of authors. SQI may be considered as an assessment tool which is more strongly determined by qualitative than quantitative features of individual scientific output. PMID- 29582220 TI - Assessing False-Belief Understanding in Children with Autism Using a Computer Application: A Pilot Study. AB - We have developed a False-Belief (FB) understanding task for use on a computer tablet, trying to assess FB understanding in a less social way. It is based on classical FB protocols, and additionally includes a manipulation of language in an attempt to explore the facilitating effect of linguistic support during FB processing. Specifically, the FB task was presented in three auditory conditions: narrative, silent, and interference. The task was assumed to shed new light on the FB difficulties often observed in Autism Spectrum Disorder (ASD). Sixty-eight children with ASD (M = 7.5 years) and an age matched comparison group with 98 typically developing (TD) children were assessed with the FB task. The children with ASD did not perform above chance level in any condition, and significant differences in success rates were found between the groups in two conditions (silent and narrative), with TD children performing better. We discuss implications, limitations, and further developments. PMID- 29582221 TI - The Influence of Learning Style on English Learning Achievement Among Undergraduates in Mainland China. AB - Learning style is one of the main factors that determines how students learn English and has a significant influence on students' learning strategy selection, which further affects their learning outcomes (Ehrman and Oxford in Mod Lang J 74(3):311-327, 1990; Oxford in Language learning styles and strategies: an overview, 2003. http://web.ntpu.edu.tw/~language/workshop/read2.pdf ). This study examines the learning style preferences of Chinese university students and whether those preferences influence their English achievements. Four hundred undergraduates from one university in eastern mainland China participated in this study. Data from 329 valid questionnaires were analysed. The results revealed that the Chinese university students preferred the visual learning style the most, followed by the auditory and kinaesthetic styles. However, no learning style preference was found to influence the students' English proficiency. Cultural reasons are discussed to explain the findings, which contradict those of previous studies of learning style theories and practices. This study recommends that Chinese scholars consider issues of English teaching and learning in China and to adopt appropriate teaching methods to effectively improve English teaching. PMID- 29582222 TI - Pre-analytical Factors Influence Accuracy of Urine Spot Iodine Assessment in Epidemiological Surveys. AB - Urinary iodine concentration (UIC) is commonly used to assess iodine status of subjects in epidemiological surveys. As pre-analytical factors are an important source of measurement error and studies about this phase are scarce, our objective was to assess the influence of urine sampling conditions on UIC, i.e., whether the child ate breakfast or not, urine void rank of the day, and time span between last meal and urine collection. A nationwide, two-stage, stratified, cross-sectional study including 1560 children (6-12 years) was performed in 2012. UIC was determined by the Sandell-Kolthoff method. Pre-analytical factors were assessed from children's mothers by using a questionnaire. Association between iodine status and pre-analytical factors were adjusted for one another and socio economic characteristics by multivariate linear and multinomial regression models (RPR: relative prevalence ratios). Skipping breakfast prior to morning urine sampling decreased UIC by 40 to 50 MUg/L and the proportion of UIC < 100 MUg/L was higher among children having those skipped breakfast (RPR = 3.2[1.0-10.4]). In unadjusted analyses, UIC was less among children sampled more than 5 h from their last meal. UIC decreased with rank of urine void (e.g., first vs. second, P < 0.001); also, the proportion of UIC < 100 MUg/L was greater among 4th rank samples (vs. second RPR = 2.1[1.1-4.0]). Subjects' breakfast status and urine void rank should be accounted for when assessing iodine status. Providing recommendations to standardize pre-analytical factors is a key step toward improving accuracy and comparability of survey results for assessing iodine status from spot urine samples. These recommendations have to be evaluated by future research.

PMID- 29582224 TI - Ramucirumab as Second-Line Therapy in Metastatic Gastric Cancer: Real-World Data from the RAMoss Study. AB - BACKGROUND: Ramucirumab-alone or combined with paclitaxel-represents one of the main options for patients failing first-line treatment for advanced gastric cancer. OBJECTIVE: The RAMoss study aimed to evaluate the safety and efficacy profile of ramucirumab in the "real-life setting". PATIENTS AND METHODS: Patients from 25 Italian hospitals started therapy consisting of ramucirumab 8 mg/kg i.v. d1,15q28 with or without paclitaxel 80 mg/m2 i.v. d1,8,15q28. The primary endpoint was safety, and secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). RESULTS: One hundred sixty-seven patients with disease progression on first-line therapy received ramucirumab as monotherapy (10%) or combined with paclitaxel (90%). Median treatment duration was 4 months (1-17 months). Global incidence of grade (G) 3-4 toxicity was 9.6%, and for neutropenia 5.4%; treatment was discontinued due to toxicity in 3% of patients. The most frequent adverse events (AE) were G1-2 fatigue (27.5%), G1-2 neuropathy (26.3%), and G1-2 neutropenia (14.9%). ORR was 20.2%. Stable disease was observed in 39.2% of patients, with a disease control rate of 59.4%. With a median follow-up of 11 months, median PFS was 4.3 months (95% confidence interval [CI] 4.1-4.7), whereas median OS was 8.0 months (95% CI: 7.09-8.9). In a multivariate analysis, ECOG performance status <1 or >=1 (HR 1.13, 95% CI 1.0-1.27, p = 0.04) and the presence versus absence of peritoneal metastases (HR 1.57, 95% CI 1.63-2.39, p = 0.03) were independent poor prognostic factors. CONCLUSIONS: These "real-life" efficacy data on ramucirumab treatment are in line with previous randomized trials. Ramucirumab is well tolerated in daily clinical practice. PMID- 29582225 TI - Outcomes in Children Treated with Pentobarbital Infusion for Refractory and Super Refractory Status Epilepticus. AB - BACKGROUND: Functional neurologic outcome for children with refractory and super refractory status epilepticus has not been well defined. METHODS: Retrospective chart review including children age 0-17 years who received pentobarbital infusion from 2003 to 2016 for status epilepticus. Outcomes were defined in terms of mortality, need for new medical technology assistance at hospital discharge and functional neurologic outcome determined by pediatric cerebral performance category score (PCPC). Potential patient characteristics associated with functional neurologic outcome including age, sex, ethnicity, etiology of the status epilepticus, and duration of pentobarbital infusion were evaluated. RESULTS: Forty children met inclusion criteria. In-hospital mortality was 30% (12/40). Of survivors, 21% (6/28) returned to baseline PCPC while half (14/28) declined in function >= 2 PCPC categories at hospital discharge. 25% (7/28) of survivors required tracheostomy and 27% (7/26) required new gastrostomy. Seizures persisted at discharge for most patients with new onset status epilepticus while the majority of patients with known epilepsy returned to baseline seizure frequency. Etiology (p = 0.015), PCPC at admission (p = 0.0006), new tracheostomy (p = 0.012), and new gastrostomy tube (p = 0.012) were associated with increase in PCPC score >= 2 categories in univariable analysis. Duration of pentobarbital infusion (p = 0.005) and length of hospital stay (p = 0.056) were longer in patients who demonstrated significant decline in neurologic function. None of these variables maintained statistical significance when multiple logistic regression model adjusting for PCPC score at admission was applied. At long-term follow-up, 36% (8/22) of children demonstrated improvement in PCPC compared to discharge and 23% (5/22) showed deterioration including three additional deaths. CONCLUSIONS: Mortality in this population was high. The majority of children experienced some degree of disability at discharge. Despite prolonged pentobarbital infusion, there were cases of survival with good neurologic outcome.

A proper renal diet represents the most efficient therapeutic intervention to improve survival and life quality in feline patients with 3 and 4 International Renal Interest Society (IRIS) stages. Twenty cats were selected in this study. Ten were administered the dietary supplementation for 360 days and the other ten, whose owners did not give consent for any supplemental therapies apart from the renal diet, were selected from a clinical database and used as control group. The present study is a long term study (360 days) aiming to evaluate the efficacy and palatability of a dietary supplementation containing calcium carbonate, calcium lactate gluconate, chitosan and sodium bicarbonate in cats diagnosed with 3 and 4 IRIS stages of CKD. The owners were asked to fill in questionnaires to get information on the cat's appetite, the palatability of the given supplement, the presence of vomit and/or diarrhoea, general health and vitality. Hematochemical, biochemical and urinary analyses were performed on day 0, 30, 60, 90, 120, 150,180 and 360. GraphPad Prism(r) software was used to perform statistical analysis. Our study shows that the given dietary supplement reduced serum phosphorus and increased serum bicarbonate values in cats with CKD. In turn, this supplement could be used as a support therapy in cats with advanced CKD improving their clinical conditions without any adverse reaction. Finally, it is important to underline that all the animals completed the study and the owners reported a good palatability of the feed supplement.

AB - The evolution of photosynthesis from primitive photosynthetic bacteria to higher plants has been driven by the need to adapt to a wide range of environmental conditions. The red alga Cyanidioschyzon merolae is a primitive organism, which is capable of performing photosynthesis in extreme acidic and hot environments. The study of its photosynthetic machinery may provide new insight on the evolutionary path of photosynthesis and on light harvesting and its regulation in eukaryotes. With that aim, the structural and functional properties of the PSI complex were investigated by biochemical characterization, mass spectrometry, and X-ray crystallography. PSI was purified from cells grown at 25 and 42 degrees C, crystallized and its crystal structure was solved at 4 A resolution. The structure of C. merolae reveals a core complex with a crescent-shaped structure, formed by antenna proteins. In addition, the structural model shows the position of PsaO and PsaM. PsaG and PsaH are present in plant complex and are missing from the C. merolae model as expected. This paper sheds new light onto the evolution of photosynthesis, which gives a strong indication for the chimerical properties of red algae PSI. The subunit composition of the PSI core from C. merolae and its associated light-harvesting antennae suggests that it is an evolutionary and functional intermediate between cyanobacteria and plants.

AB - Indigenous ancestral teachings commonly present individual and community health as dependent upon relationships between human and nonhuman worlds. But how do persons conversant with ancestral teachings effectively convey such perspectives in contemporary contexts, and to what extent does the general tribal citizenry share them? Can media technology provide knowledge keepers with opportunities to communicate their perspectives to larger audiences? What are the implications for tribal citizens' knowledge and views about tribal land use policies? Using a PhotoVoice approach, we collaborated with a formally constituted body of Cherokee elders who supply cultural guidance to the Cherokee Nation government in Oklahoma. We compiled photographs taken by the elders and conducted interviews with them centered on the project themes of land and health. We then developed a still-image documentary highlighting these themes and surveyed 84 Cherokee citizens before and after they viewed it. Results from the pre-survey revealed areas where citizens' perspectives on tribal policy did not converge with the elders' perspectives; however, the post-survey showed statistically significant changes. We conclude that PhotoVoice is an effective method to communicate elders' perspectives, and that tribal citizens' values about tribal land use may change as they encounter these perspectives in such novel formats.

AB - Antagonism of CCR9 is a promising mechanism for treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. There is limited experimental data on CCR9 and its ligands, complicating efforts to identify new small molecule antagonists. We present here results of a successful virtual screening and rational hit-to-lead campaign that led to the discovery and initial optimization of novel CCR9 antagonists. This work uses a novel data fusion strategy to integrate the output of multiple computational tools, such as 2D similarity search, shape similarity, pharmacophore searching, and molecular docking, as well as the identification and incorporation of privileged chemokine fragments. The application of various ranking strategies, which combined consensus and parallel selection methods to achieve a balance of enrichment and novelty, resulted in 198 virtual screening hits in total, with an overall hit rate of 18%. Several hits were developed into early leads through targeted synthesis and purchase of analogs. PMID- 29582230 TI - Binding free energy calculations to rationalize the interactions of huprines with acetylcholinesterase. AB - In the present study, the binding free energy of a family of huprines with acetylcholinesterase (AChE) is calculated by means of the free energy perturbation method, based on hybrid quantum mechanics and molecular mechanics potentials. Binding free energy calculations and the analysis of the geometrical parameters highlight the importance of the stereochemistry of huprines in AChE inhibition. Binding isotope effects are calculated to unravel the interactions between ligands and the gorge of AChE. New chemical insights are provided to explain and rationalize the experimental results. A good correlation with the experimental data is found for a family of inhibitors with moderate differences in the enzyme affinity. The analysis of the geometrical parameters and interaction energy per residue reveals that Asp72, Glu199, and His440 contribute significantly to the network of interactions between active site residues, which stabilize the inhibitors in the gorge. It seems that a cooperative effect of the residues of the gorge determines the affinity of the enzyme for these inhibitors, where Asp72, Glu199, and His440 make a prominent contribution. PMID- 29582231 TI - Amino acid substitutions in low pathogenic avian influenza virus strains isolated from wild birds in Korea. AB - Wild birds are natural hosts and reservoirs for influenza A viruses. However, many species, such as many waterfowl, are asymptomatic when infected and so facilitate the generation of viral genetic diversity. Mutations of key genes affect the replicability, pathogenicity, transmissibility, and antiviral resistance of influenza A viruses. In this study, we isolated avian influenza (AI) viruses from wild bird fecal samples and analyzed changes in amino acids over time and geographic region to monitor the biological change of the AI virus. Between 2014 and 2016, we collected 38,921 fresh fecal samples from major wild bird habitats located throughout Korea and isolated 123 AI viruses. We subsequently selected 22 amino acid sites to analyze for changes. These sites included ten sites associated with replication, ten sites associated with pathogenicity, three sites associated with transmission, and seven sites associated with antiviral resistance. We found substitution rates of 71.7% at the C38Y amino acid site within the polymerase basic protein 1 (PB1) gene, 66.7% at the D222G site within the hemagglutinin (HA) 1 gene, and 75.6% at the A184 site within the nucleoprotein (NP) gene. Alterations of the PB1, HA1, and NP genes are closely associated with increased pathogenicity in chickens and mammals. The remaining sites of interest exhibited few modifications. In this study, we confirmed that AI viruses circulating among wild birds in Korea consistently exhibit modifications at amino acid sites linked with replication and pathogenicity. PMID- 29582232 TI - Challenges to Effective Primary Care-Specialty Communication and Coordination in the Mental Health Referral and Care Process for Publicly Insured Children. AB - Publicly insured children needing referral to mental health (MH) services often do not access or receive services. The objective of this study was to identify gaps in communication and coordination between primary care providers (PCPs) and MH providers during the MH referral and care process for publicly insured children. Thirteen semi-structured interviews were conducted with 10 PCPs and staff from a federally qualified health center (FQHC) and 6 MH providers and staff from two local MH clinics. Interview participants identified multiple gaps in communication throughout the care process and different phases as priorities for improvement. PCPs described primary care-MH communication challenges during early phases, while MH providers described coordination challenges in transferring patients back to primary care for ongoing mental health management. Strategies are needed to improve primary care-specialty MH communication and coordination throughout all phases of the referral and care process, particularly at initial referral and transfer back to primary care. PMID- 29582233 TI - Economic Evaluation of the Juvenile Drug Court/Reclaiming Futures (JDC/RF) Model. AB - Juvenile drug court (JDC) programs are an increasingly popular option for rehabilitating juvenile offenders with substance problems, but research has found inconsistent evidence regarding their effectiveness and economic impact. While assessing client outcomes such as reduced substance use and delinquency is necessary to gauge program effectiveness, a more comprehensive understanding of program success and sustainability can be attained by examining program costs and economic benefits. As part of the National Cross-Site Evaluation of JDC and Reclaiming Futures (RF), an economic analysis of five JDC/RF programs was conducted from a multisystem and multiagency perspective. The study highlights the direct and indirect costs of JDC/RF and the savings generated from reduced health problems, illegal activity, and missed school days. Results include the average (per participant) cost of JDC/RF, the total economic benefits per JDC/RF participant, and the net savings of JDC/RF relative to standard JDC.

AB - The Access to Allied Psychological Services (ATAPS) Suicide Prevention Services initiative is an Australian Government-funded primary mental healthcare initiative providing free intensive psychological intervention for consumers at moderate risk of self-harm or suicide. Findings from a multi-method evaluation aimed at identifying whether the initiative is being implemented as stipulated within the operational guidelines, barriers and facilitators to implementation, and preliminary outcomes suggest that the Suicide Prevention Services are largely being implemented as stipulated in the Guidelines, but with some exceptions. In particular, service delivery barriers unique to rural and remote areas place limitations on implementation. Uptake of the ATAPS Suicide Prevention Services is high (10,428 consumers were referred to the Suicide Prevention Services between October 2008 and April 2013, and 86% of those attended at least one session), as is acceptance from organizations involved in its implementation. PMID- 29582235 TI - Characterization of isolated liver sinusoidal endothelial cells for liver bioengineering. AB - BACKGROUND: The liver sinusoidal capillaries play a pivotal role in liver regeneration, suggesting they may be beneficial in liver bioengineering. This study isolated mouse liver sinusoidal endothelial cells (LSECs) and determined their ability to form capillary networks in vitro and in vivo for liver tissue engineering purposes. METHODS AND RESULTS: In vitro LSECs were isolated from adult C57BL/6 mouse livers. Immunofluorescence labelling indicated they were LYVE 1+/CD32b+/FactorVIII+/CD31-. Scanning electron microscopy of LSECs revealed the presence of characteristic sieve plates at 2 days. LSECs formed tubes and sprouts in the tubulogenesis assay, similar to human microvascular endothelial cells (HMEC); and formed capillaries with lumens when implanted in a porous collagen scaffold in vitro. LSECs were able to form spheroids, and in the spheroid gel sandwich assay produced significantly increased numbers (p = 0.0011) of capillary like sprouts at 24 h compared to HMEC spheroids. Supernatant from LSEC spheroids demonstrated significantly greater levels of vascular endothelial growth factor-A and C (VEGF-A, VEGF-C) and hepatocyte growth factor (HGF) compared to LSEC monolayers (p = 0.0167; p = 0.0017; and p < 0.0001, respectively), at 2 days, which was maintained to 4 days for HGF (p = 0.0017) and VEGF-A (p = 0.0051). In vivo isolated mouse LSECs were prepared as single cell suspensions of 500,000 cells, or as spheroids of 5000 cells (100 spheroids) and implanted in SCID mouse bilateral vascularized tissue engineering chambers for 2 weeks. Immunohistochemistry identified implanted LSECs forming LYVE-1+/CD31- vessels. In LSEC implanted constructs, overall lymphatic vessel growth was increased (not significantly), whilst host-derived CD31+ blood vessel growth increased significantly (p = 0.0127) compared to non-implanted controls. LSEC labelled with the fluorescent tag DiI prior to implantation formed capillaries in vivo and maintained LYVE-1 and CD32b markers to 2 weeks. CONCLUSION: Isolated mouse LSECs express a panel of vascular-related cell markers and demonstrate substantial vascular capillary-forming ability in vitro and in vivo. Their production of liver growth factors VEGF-A, VEGF-C and HGF enable these cells to exert a growth stimulus post-transplantation on the in vivo host-derived capillary bed, reinforcing their pro-regenerative capabilities for liver tissue engineering studies.

PMID- 29582237 TI - Locations and Mucosal Lesions Responsible for Major Gastrointestinal Bleeding in Patients on Warfarin or Dabigatran. AB - BACKGROUND AND AIM: Different oral anticoagulants may be associated with gastrointestinal bleeding (GIB) from different locations or mucosal lesions. We aimed to test this hypothesis. METHODS: Two blinded gastroenterologists independently analyzed source documents from the randomized evaluation of long term anticoagulant therapy (RE-LY) trial of dabigatran 150 mg BID (D150), dabigatran 110 mg BID (D110) versus warfarin in non-valvular atrial fibrillation (NVAF). RESULTS: Major GIB events (total n = 546) and life-threatening GIB events (n = 258) were more common with D150 versus warfarin (RR 1.57 [1.28-1.92] and RR 1.62 [1.20-2.18], respectively) and similar for D110 compared to warfarin (RR 1.11 [0.89-1.38] and RR 1.16 [0.84-1.61], respectively). Fatal bleeding was similarly rare across treatment groups. Lower GI major bleeding and life threatening bleeding were more common with D150 compared to warfarin (RR 2.23 [1.47, 3.38] and RR 2.64 [1.36, 5.13], respectively) and with D110 compared to warfarin (RR 1.78 [1.16, 2.75] and RR 2.00 [1.00, 4.00], respectively). MGIB from colonic angiodysplasia was increased with dabigatran versus warfarin (P < 0.01 for both dose comparisons). Subacute and chronic MGIB events were more common with D150 than with warfarin (RR 1.72 [1.06, 2.78] and RR 1.66 [1.12, 2.45], respectively), as were hematochezia or melena (RR 1.67 [1.18, 2.36] and RR 1.72 [1.20, 2.47], respectively). CONCLUSIONS: In a chronic NVAF population, D150 but not D110 is associated with increased major and life-threatening GI bleeding in comparison with warfarin. At both dabigatran doses, increased bleeding from the colorectum, in particular from angiodysplasia, is seen. PMID- 29582238 TI - Influence of tube potential on quantitative coronary plaque analyses by low radiation dose computed tomography: a phantom study. AB - Previous studies have shown that employing the low dose computed tomography (CT) technique based on low tube potential reduces the radiation dose required for the coronary artery examination protocol. However, low tube potential may adversely influence the CT number of plaque composition. Therefore, we aimed to determine whether quantitative atherosclerotic plaque analysis by a multi-slice, low radiation dose CT protocol using 80 kilovolts (kV) yields results comparable to those of the standard 120 kV protocol. Artificial plaque samples (n = 17) composed of three kinds of plaque were scanned at 120 and 80 kV. Relative low density and medium-density plaque component volumes obtained by three protocols (80 kV, 60 Hounsfield units [HU] threshold; 120 kV, 60 HU threshold; and 80 kV, 82 HU threshold) were compared. Using the 60 HU threshold, relative volume of the low-density plaque component obtained at 80 kV was lower than that obtained at 120 kV (27 +/- 3% vs. 51 +/- 5%, P < 0.001), whereas relative volume of the medium-density plaque component obtained at 80 kV was higher than that obtained at 120 kV (73 +/- 3% vs. 48 +/- 5%, P < 0.001). By contrast, no significant difference in relative volume obtained at 80 kV (82 HU threshold) versus 120 kV (60 HU threshold) was observed for either low-density (52 +/- 5% vs. 51 +/- 5%) or medium-density (48 +/- 5% vs. 48 +/- 5%) plaque component. Low tube potential may affect the accuracy of quantitative atherosclerotic plaque analysis. For our phantom test, 82 HU was the optimal threshold for scanning at 80 kV.

AB - OBJECTIVE: B6, an analog of curcumin, is a compound isolated from a traditional Chinese medicine Turmeric. In this paper, we aimed to explore the efficacy of B6 on diabetic nephropathy and the related mechanisms. MATERIALS AND METHODS: The effects of B6 were studied on fast-blood glucose, serum creatinine, urea nitrogen, urine albumen/24 h, pathological changes of main organs, the levels of ACE2 and ACE2 mRNA in the rat model of diabetes induced by streptozotocin. RESULTS: The results showed that B6 treatment could reduce serum creatinine, urea nitrogen, urine albumen/24 h, decrease the level of AngII, improve the renal pathological changes in diabetic rats and increase the levels of ACE2 and ACE2 mRNA. CONCLUSION: These results suggested B6 could protect the renal function of diabetic rats. This study provided scientific basis for the further researches and clinical applications of B6. PMID- 29582240 TI - Enhancement of drug permeability across blood brain barrier using nanoparticles in meningitis. AB - The central nervous system, one of the most delicate microenvironments of the body, is protected by the blood-brain barrier regulating its homeostasis. Blood brain barrier is a highly complex structure that tightly regulates the movement of ions of a limited number of small molecules and of an even more restricted number of macromolecules from the blood to the brain, protecting it from injuries and diseases. However, the blood-brain barrier also significantly precludes the delivery of drugs to the brain, thus, preventing the therapy of a number of neurological disorders. As a consequence, several strategies are currently being sought after to enhance the delivery of drugs across the blood-brain barrier. Within this review a brief description of the structural and physiological features of the barriers and the recently born strategy of brain drug delivery based on the use of nanoparticles are described. Finally, the future technological approaches are described. The strong efforts to allow the translation from preclinical to concrete clinical applications are worth the economic investments. PMID- 29582242 TI - Automatic Pectoral Muscle Region Segmentation in Mammograms Using Genetic Algorithm and Morphological Selection. AB - In computer-aided diagnosis systems for breast mammography, the pectoral muscle region can easily cause a high false positive rate and misdiagnosis due to its similar texture and low contrast with breast parenchyma. Pectoral muscle region segmentation is a crucial pre-processing step to identify lesions, and accurate segmentation in poor-contrast mammograms is still a challenging task. In order to tackle this problem, a novel method is proposed to automatically segment pectoral muscle region in this paper. The proposed method combines genetic algorithm and morphological selection algorithm, incorporating four steps: pre-processing, genetic algorithm, morphological selection, and polynomial curve fitting. For the evaluation results on different databases, the proposed method achieves average FP rate and FN rate of 2.03 and 6.90% (mini MIAS), 1.60 and 4.03% (DDSM), and 2.42 and 13.61% (INBreast), respectively. The results can be comparable performance in various metrics over the state-of-the-art methods. PMID- 29582243 TI - Monte Carlo simulations for dose enhancement in cancer treatment using bismuth oxide nanoparticles implanted in brain soft tissue. AB - The objective of this work is to study the dosimetric performances of bismuth oxide nanoparticles implanted in tumors in cancer radiotherapy. GEANT4 based Monte Carlo numerical simulations were performed to assess dose enhancement distributions in and around a 1 * 1 * 1 cm3 tumor implanted with different concentrations of bismuth oxide and irradiated with low energies 125I, 131Cs, and 103Pd radioactive sources. Dose contributions were considered from photoelectrons, Auger electrons, and characteristic X-rays. Our results show the dose enhancement increased with increasing both bismuth oxide concentration in the target and photon energy. A dose enhancement factor up to 18.55 was obtained for a concentration of 70 mg/g of bismuth oxide in the tumor when irradiated with 131Cs source. This study showed that bismuth oxide nanoparticles are innovative agents that could be potentially applicable to in vivo cancer radiotherapy due to the fact that they induce a highly localized energy deposition within the tumor.

AB - NAD and NADP, a pivotal class of cofactors, which function as essential electron donors or acceptors in all biological organisms, drive considerable catabolic and anabolic reactions. Furthermore, they play critical roles in maintaining intracellular redox homeostasis. However, many metabolic engineering efforts in industrial microorganisms towards modification or introduction of metabolic pathways, especially those involving consumption, generation or transformation of NAD/NADP, often induce fluctuations in redox state, which dramatically impede cellular metabolism, resulting in decreased growth performance and biosynthetic capacity. Here, we comprehensively review the cofactor engineering strategies for solving the problematic redox imbalance in metabolism modification, as well as their features, suitabilities and recent applications. Some representative examples of in vitro biocatalysis are also described. In addition, we briefly discuss how tools and methods from the field of synthetic biology can be applied for cofactor engineering. Finally, future directions and challenges for development of cofactor redox engineering are presented. PMID- 29582244 TI - A Comparison of Five Algorithms for Fetal Magnetocardiography Signal Extraction. AB - Fetal magnetocardiography (fMCG) provides accurate and reliable measurements of electrophysiological events in the fetal heart and is capable of studying fetuses with congenital heart diseases. A variety of techniques exist to extract the fMCG signal with the demand for non-invasively obtained fetal cardiac information. To the best of our knowledge, there is no comparative study published in the field as to how the various extraction algorithms perform. We perform a comparative study of the ability of five methods to extract the fMCG using real biomagnetic signals, two of those methods are applied to real fMCG data for the first time. Biomagnetic signals were recorded and processed with each of the five methods to obtain fMCG. The R peaks of the fMCG traces were obtained via a peak-detection algorithm. From whole recording for each method, the fetal heart rate (FHR) was calculated and used to perform FHR variability (FHRV) analysis. Additionally, we calculated durations from the PQRST complex from time-averaged data during sinus rhythm. The five methods recovered the fMCG signals, but two of them were able to extract cleaner fMCG and the morphology was observed from the continuous data. The time-averaged data showed very similar morphologies between methods, but two of them displayed a signal amplitude reduction on the R-waves and T-waves. Values of PQRST durations, FHR and FHRV were in the range of previous fetal cardiac studies. We have compared five methods for fMCG extraction and showed their ability to perform fMCG analysis. PMID- 29582245 TI - Quantum Calculations on Plant Cell Wall Component Interactions. AB - Density functional theory calculations were performed to assess the relative interaction energies of plant cell wall components: cellulose, xylan, lignin and pectin. Monomeric and tetramer linear molecules were allowed to interact in four different configurations for each pair of compounds. The M05-2X exchange correlation functional which implicitly accounts for short- and mid-range dispersion was compared against MP2 and RI-MP2 to assess the reliability of the former for modeling van der Waals forces between these PCW components. Solvation effects were examined by modeling the interactions in the gas phase, in explicit H2O, and in polarized continuum models (PCM) of solvation. PCMs were used to represent water, methanol, and chloroform. The results predict the relative ranges of each type of interaction and when specific configurations will be strongly preferred. Structures and energies are useful as a basis for testing classical force fields and as guidance for coarse-grained models of PCWs. PMID- 29582246 TI - Current Treatment Patterns Among Postmenopausal Women with HR+/HER2- Metastatic Breast Cancer in US Community Oncology Practices: An Observational Study. AB - INTRODUCTION: Recent approval of novel agents has changed the treatment landscape for post menopausal women with hormone receptor-positive (HR+) and human epidermal growth factor receptor-2 negative (HER2-) metastatic breast cancer (mBC). The objective of this study was to describe contemporary treatment patterns among postmenopausal women with HR+/HER2- mBC in the real-world setting. METHODS: Data were collected from 64 community oncologists in the US between February and June 2017 using an online medical records extraction tool. Physicians reviewed medical records and provided information on patient demographics and disease characteristics, and treatment regimens. Treatment patterns were described overall and separately by line of therapy and type of treatment received. Discontinuation rates were estimated using Kaplan-Meier analyses to account for censoring. RESULTS: Data were collected on 401 patients. Mean age at the time of mBC diagnosis was 67 years. In the first-line setting, 52.4% of patients received a cyclin-dependent kinase 4/6 (CDK4/6) inhibitor-based regimen, most commonly with an aromatase inhibitor (AI) (39.2%) or fulvestrant (10.0%); 30.2% received endocrine therapy, most commonly an AI (21.4%) or fulvestrant (5.2%) in monotherapy, while 12.7% received a chemotherapy-based regimen. In the second-line setting, 42.9% of patients received a CDK4/6 inhibitor-based regimen, 18.4% received endocrine therapy, and 22.4% received a chemotherapy-based regimen. The 18-month discontinuation rate was 34.5% for patients receiving a CDK4/6 inhibitor-based regimen and 45.8% for patients receiving endocrine monotherapy. CONCLUSION: CDK4/6 inhibitor-based regimens were the most commonly prescribed treatment in both first- and second-line settings. A wide variety of treatment sequences were observed which suggests an absence of a standard of care for postmenopausal women with HR+/HER2- mBC in real-world practice. PMID- 29582248 TI - Safety and Pharmacokinetics of DS-8500a, a Novel GPR119 Agonist, After Multiple Oral Doses in Healthy Japanese Males. AB - BACKGROUND AND OBJECTIVES: G protein-coupled receptor 119 (GPR119) agonists reduce plasma glucose by promoting insulin secretion in a glucose-dependent manner. We evaluated the safety and pharmacokinetics of multiple oral doses of DS 8500a, a GPR119 agonist, under fed conditions in healthy adult Japanese male subjects. METHODS: In this Phase 1, randomized, placebo-controlled, double-blind, multiple oral dose study, participants were aged >= 20 and <= 45 years with a body mass index >= 18.5 and < 25.0 kg/m2. DS-8500a 50 and 100 mg or placebo were administered orally, once daily, 30 min after breakfast for 7 days. The primary endpoints were pharmacokinetics and safety. RESULTS: Twenty-four subjects were included (6, 9, and 9 in the placebo, 50-, and 100-mg groups, respectively). On Day 7, the mean maximum plasma concentration (Cmax) was 812 ng/mL in the 50-mg group and 1310 ng/mL in the 100-mg group. The mean area under the plasma concentration-time curve during dosing interval (AUCtau) was 7910 and 13,200 ng.h/mL in the two treatment groups, respectively. The observed accumulation ratio was 1.25 in the 50-mg group and 1.32 in the 100-mg group. All adverse events were mild and judged unrelated to the study drug. CONCLUSIONS: DS-8500a plasma concentrations reached steady state from Day 3, and Cmax and AUCtau increased in a less than dose-proportional manner. After repeated doses of DS 8500a at 100 mg, the DS-8500a trough concentration was expected to reach a pharmacologically active dose. DS-8500a was well tolerated up to 100 mg after a 7 day administration. STUDY REGISTRY IDENTIFICATION: JAPIC ID: JapicCTI-173550 (registered retrospectively on 30 March 2017). PMID- 29582247 TI - TaEDS1 genes positively regulate resistance to powdery mildew in wheat. AB - KEY MESSAGE: Three EDS1 genes were cloned from common wheat and were demonstrated to positively regulate resistance to powdery mildew in wheat. The EDS1 proteins play important roles in plant basal resistance and TIR-NB-LRR protein-triggered resistance in dicots. Until now, there have been very few studies on EDS1 in monocots, and none in wheat. Here, we report on three common wheat orthologous genes of EDS1 family (TaEDS1-5A, 5B and 5D) and their function in powdery mildew resistance. Comparisons of these genes with their orthologs in diploid ancestors revealed that EDS1 is a conserved gene family in Triticeae. The cDNA sequence similarity among the three TaEDS1 genes was greater than 96.5%, and they shared sequence similarities of more than 99.6% with the respective orthologs from diploid ancestors. The phylogenetic analysis revealed that the EDS1 family originated prior to the differentiation of monocots and dicots, and EDS1 members have since undergone clear structural differentiation. The transcriptional levels of TaEDS1 genes in the leaves were obviously higher than those of the other organs, and they were induced by Blumeria graminis f. sp. tritici (Bgt) infection and salicylic acid (SA) treatment. The BSMV-VIGS experiments indicated that knock down the transcriptional levels of the TaEDS1 genes in a powdery mildew-resistant variety of common wheat compromised resistance. Contrarily, transient overexpression of TaEDS1 genes in a susceptible common wheat variety significantly reduced the haustorium index and attenuated the growth of Bgt. Furthermore, the expression of TaEDS1 genes in the Arabidopsis mutant eds1-1 complemented its susceptible phenotype to powdery mildew. The above evidences strongly suggest that TaEDS1 acts as a positive regulator and confers resistance against powdery mildew in common wheat. PMID- 29582249 TI - Fluticasone Propionate/Salmeterol MDPI (AirDuo RespiClick(r)): A Review in Asthma. AB - The novel, easy-to-use, breath-actuated fluticasone propionate/salmeterol multidose dry powder inhaler (MDPI) (AirDuo RespiClick(r)) was recently approved in the USA for twice-daily treatment of asthma in patients aged >= 12 years. This inhaled corticosteroid (ICS) and long-acting beta2-adrenoreceptor agonist (LABA) combination treatment is available in low-, mid- and high-dosage formulations (55/14, 113/14 and 232/14 MUg, respectively). In 12-week, phase III trials in patients aged >= 12 years with persistent asthma, all three dosages of fluticasone propionate/salmeterol MDPI treatment produced significant improvements in lung function and other asthma symptoms compared with fluticasone propionate MDPI monotherapy or placebo MDPI. In a 26-week, phase III trial in this patient population, mid- and high-dosage fluticasone propionate/salmeterol MDPI were noninferior to mid- (250/50 MUg) and high- (500/50 MUg) dosage fluticasone propionate/salmeterol DPI (Advair Diskus(r)), respectively, in terms of improvements in lung function. Treatment-emergent adverse events (TEAEs) with fluticasone propionate/salmeterol MDPI were mostly of mild to moderate severity, with no severe TEAEs deemed to be treatment related. Although long-term pharmacovigilance is required to fully establish its safety, given the ease of use and favorable characteristics of the device and its clinical efficacy at relatively low metered doses of the active moieties, fluticasone propionate/salmeterol MDPI is an important emerging treatment option in patients aged >= 12 years with asthma.

PMID- 29582252 TI - Safety and efficacy of alternate-day corticosteroid treatment as adjunctive therapy for rheumatoid arthritis: a comparative study. AB - Corticosteroids (CSs), used to treat rheumatoid arthritis (RA), confer a risk of adverse events (AEs). This study investigated the safety and efficacy of alternate-day (QOD) CS therapy for RA. All patients (> 18 years) who started oral CS therapy for RA, between 2005 and 2014, at our hospital were retrospectively analysed. The patients were divided into the daily (QD) and QOD CS therapy groups to investigate the rates of CS-related major AEs (infection, diabetes, hypertension, cardiovascular events and fragility fractures) within the first year of treatment. The number of patients free from CS treatment at 1 year and the mean decreases in C-reactive protein (CRP) levels at 1 month were also investigated. In total, 138 patients were analysed (QD group, 68; QOD group, 70). The maximum daily CS dose was not significantly different between the two groups, but the annual cumulative dose was significantly lower in the QOD group (P < 0.01). The infection rate was significantly lower in the QOD group (24.3%) than in the QD group (50.0%; P < 0.01), whereas the other AE rates were similar between the groups. The CS-free rate at 1 year was significantly higher in the QOD group (58.6%) than in the QD group (26.5%; P < 0.01). The mean CRP decreases over 1 month of CS therapy were not significantly different between the groups. QOD CS treatment leads to a lower infection rate and less CS dependence than does daily treatment; both RA treatments are equally effective.

AB - Aflatoxin B1 is a potent hepatotoxin and carcinogen that poses a serious safety hazard to both humans and animals. Aspergillus flavus is the most common aflatoxin-producing species on corn, cotton, peanuts, and tree nuts. Application of atoxigenic strains to compete against aflatoxigenic strains of A. flavus has emerged as one of the most practical strategies for ameliorating aflatoxin contamination in food. Genes directly involved in aflatoxin biosynthesis are clustered on an 82-kb region of the genome. Three atoxigenic strains (CA12, M34, and AF123) were each paired with each of four aflatoxigenic strains (CA28, CA42, CA90, and M52), inoculated into soil and incubated at 28 degrees C for 2 weeks and 1 month. TaqMan probes, omtA-FAM, and norA-HEX were designed for developing a droplet digital PCR (ddPCR) assay to analyze the soil population of mixtures of A. flavus strains. DNA was extracted from each soil sample and used for ddPCR assays. The data indicated that competition between atoxigenic and aflatoxigenic was strain dependent. Variation in competitive ability among different strains of A. flavus influenced the population reduction of the aflatoxigenic strain by the atoxigenic strain. Higher ratios of atoxigenic to aflatoxigenic strains increased soil population of atoxigenic strains. This is the first study to demonstrate the utility of ddPCR to quantify mixtures of both atoxigenic and aflatoxigenic A. flavus strains in soil and allows for rapid and accurate determination of population sizes of atoxigenic and aflatoxigenic strains. This method eliminates the need for isolation and identification of individual fungal isolates from experimental soil samples. PMID- 29582250 TI - Opposite Interplay Between the Canonical WNT/beta-Catenin Pathway and PPAR Gamma: A Potential Therapeutic Target in Gliomas. AB - In gliomas, the canonical Wingless/Int (WNT)/beta-catenin pathway is increased while peroxisome proliferator-activated receptor gamma (PPAR-gamma) is downregulated. The two systems act in an opposite manner. This review focuses on the interplay between WNT/beta-catenin signaling and PPAR-gamma and their metabolic implications as potential therapeutic target in gliomas. Activation of the WNT/beta-catenin pathway stimulates the transcription of genes involved in proliferation, invasion, nucleotide synthesis, tumor growth, and angiogenesis. Activation of PPAR-gamma agonists inhibits various signaling pathways such as the JAK/STAT, WNT/beta-catenin, and PI3K/Akt pathways, which reduces tumor growth, cell proliferation, cell invasiveness, and angiogenesis. Nonsteroidal anti inflammatory drugs, curcumin, antipsychotic drugs, adiponectin, and sulforaphane downregulate the WNT/beta-catenin pathway through the upregulation of PPAR-gamma and thus appear to provide an interesting therapeutic approach for gliomas. Temozolomide (TMZ) is an antiangiogenic agent. The downstream action of this opposite interplay may explain the TMZ-resistance often reported in gliomas. PMID- 29582254 TI - 2,4 Dinitrophenol Attenuates Mitochondrial Dysfunction and Improves Neurobehavioral Outcomes Postanoxia in Neonatal Rats. AB - Following anoxia, a rapid and marked mitochondrial-linked cell death occurs in the cerebral cortex of newborn rats which leads to insult advancement within a couple of days and causes lifelong neurobehavioral abnormalities. The present study investigated the role of 2,4 dinitrophenol (2,4 DNP) in three doses, i.e.,1, 2.5, and 5 mg/kg on anoxia-induced time-dependent mitochondrial dysfunction and associated neurobehavioral outcome using a well-established global model of anoxia. Briefly, rat pups of 30-h age (P2) were subjected to two episodes of anoxia (10 min each) at 24 h of the time interval in an enclosed chamber supplied with 100% N2 and immersed in a water bath (35-37 degrees C) to avoid hypothermia. Results demonstrated that the uncoupler 2,4 DNP, in the dose 2.5 and 5 mg/kg injected i.p. within 5 min after second anoxic episode significantly (P < 0.05) preserved mitochondrial function on day 7 preferentially by maintaining mitochondrial membrane potential (MMP) and inhibiting mitochondrial permeability transition (MPT) pore. Further, 2,4 DNP preserved mitochondrial function by improving different states of mitochondrial respiration (s2, s3, s4, s5), respiratory control ratio (RCR), antioxidant enzyme system like superoxide dismutase (SOD) and catalase (CAT), and mitochondrial complex enzymes (I, II, IV, V) after anoxia. Furthermore, a marked decrease in the levels of expression of cytochrome C (cyt C) and pro-apoptotic (Bcl-2 family) and apoptotic (caspase-9/3) proteins was observed on day 7 indicating that the treatment with 2,4 DNP prevented mitochondrial dysfunction and further insult progression (day 1 to day 7). Moreover, 2,4 DNP decreased the apoptotic cell death on day 7 and overall improved the neurobehavioral outcomes like reflex latency and hanging latency which suggests its role in treating neonatal anoxia.

PMID- 29582257 TI - Measurement of extraocular horizontal muscle insertion distance via anterior segment optical coherence tomography of healthy children and comparison with healthy adults. AB - PURPOSE: The aim of the study was to determine the corneal limbus-extraocular muscle insertion distance (LID), via anterior segment optical coherence tomography, in healthy children and healthy adults and to compare the results of the measurements of the two groups. METHODS: Muscle limbus distances were measured using AS-OCT in 60 healthy cases in two groups. Children aged 8-13 years were evaluated as group 1, and healthy adults aged 25-30 years were evaluated as group 2. Measurements of 120 horizontal muscles were taken by one doctor (OBO). The values were compared according to age and gender groups, and correlation between LID measurements and spherical equivalent. Statistical evaluation was performed using SPSS 16(r) for Windows with the Student's t test and Pearson correlation coefficient test. RESULTS: LID measurements for MR and for lateral rectus (LR) were 5.74 +/- 0.75 and 6.74 +/- 1.11 mm, in the pediatric age-group, and 5.73 +/- 0.75 and 6.84 +/- 1.15 mm, in the adult age-group, respectively. There was no statistically significant difference between the two groups in terms of MR distances. There was a slight increase in the adult values, for the LR distance. There was no significant difference in terms of gender. Correlation was found 0.62 for MR and 0.46 for LR between LID measurements and spherical equivalent in the pediatric age-group. CONCLUSIONS: In healthy individuals, different imaging modalities can be used to measure LID, but AS-OCT can be used in pediatric age-groups as a preferred imaging method because it is easy and noninvasive. PMID- 29582256 TI - Probiotic treatment reduces the autistic-like excitation/inhibition imbalance in juvenile hamsters induced by orally administered propionic acid and clindamycin. AB - Increasing evidence suggests that the gut microbiota plays a key role in the central nervous system (CNS), and alterations of the gut microbiota composition due to environmental factors can contribute to neurodevelopmental disorders. Animal modeling may help to identify drugs that can normalize the altered gut microbiota and thereby ameliorate abnormal brain signaling pathways. The purpose of the present study was to investigate the therapeutic potency of probiotics such as Bifidobacteria and Lactobacilli on glutamate excitotoxicity as a neurotoxic effect induced by clindamycin and propionic acid (PPA) in juvenile hamsters. Fifty young golden Syrian hamsters weighing between 60 and 70 g were enrolled in the study. The hamsters were randomly divided into five groups, each with ten hamsters. The hamsters in the control group only received phosphate buffered saline orally. The PPA-treated group received a neurotoxic dose of 250 mg PPA/kg body weight (BW)/day for three days. The clindamycin-treated group received 30 mg clindamycin/kg BW as a single orogastric dose on the day the experiment started. The two therapeutic groups received the same doses of PPA and clindamycin followed by 0.2 g probiotic/kg BW for three weeks. Biochemical parameters related to glutamate excitotoxicity were investigated in brain homogenates from each group of hamsters. Additionally, the development of pathogenic bacteria was monitored in stool samples from all groups. The microbiology results of the present study revealed descriptive changes in the fecal microbiota and the appearance of Clostridium species in the hamsters treated with clindamycin and PPA. Additionally, the effectiveness of the probiotic in the restoration of the normal gut microbiota was demonstrated. Moreover, clindamycin and PPA were found to induce a significant depletion of Mg2+ and gamma-aminobutyric acid (GABA) and a remarkable increase in the Na+/Mg2+ and glutamate/GABA ratios but non-significant changes in the absolute levels of K+, Na+ and glutamate. The bacteria overgrowth induced by PPA and clindamycin in the present study effectively showed signs of neuronal toxicity. The study indicates that probiotics can be used safely to ameliorate glutamate excitotoxicity mostly through increasing depleted GABA and Mg2+ and decreasing the excitatory neurotransmitter, glutamate. PMID- 29582258 TI - Strabismus surgery for diplopia in chronic progressive external ophthalmoplegia. AB - BACKGROUND: To report midterm outcomes of strabismus strategy for management of diplopia in chronic progressive external ophthalmoplegia and specific surgical planning rationale. DESIGN: Retrospective interventional case series. RESULTS: Two patients, a 26-year-old male and a 36-year-old female, diagnosed with chronic progressive external ophthalmoplegia presented with blepharoptosis and intermittent diplopia. Ocular motility examination was significant for bilateral profound impairment of adduction with relative preservation of abduction, infraduction and elevation. Control of intermittent exotropia gradually worsened over 3 and 1.5 years of follow-up, respectively, in the presence of documented stability of the angle of exodeviation. Strabismus surgery involving modest amounts of bilateral medial rectus resection and lateral rectus recessions was undertaken. Surgical intervention was successful in controlling alignment in primary position and alleviating diplopia and asthenopia after 9 and 8 years of follow-up time, respectively, despite slow progression of ophthalmoplegia. CONCLUSION: Bilateral selective impairment of adduction and intermittent exotropia may be the presenting ocular motility disturbance in chronic progressive external ophthalmoplegia. Properly designed strabismus surgery may provide sustainable, in the midterm, control of alignment and symptomatic relief in selected patients with CPEO. PMID- 29582259 TI - Corneal densitometry after accelerated corneal collagen cross-linking in progressive keratoconus. AB - PURPOSE: To analyze changes in corneal densitometry 3 months after accelerated corneal collagen cross-linking (CXL) measured with Scheimpflug tomography. METHODS: In this study we reviewed charts and anterior segment data of patients who had undergone accelerated pulsed epithelium-off CXL (30 mW/cm2 for 4 min, 8 min total radiation time) for treatment of progressive keratoconus in the Department of Ophthalmology, Goethe University, Frankfurt, Germany. Visual, topographic, pachymetric and densitometric data were extracted before surgery and at the 3-month follow-up. Corneal densitometry measurements from different corneal layers and zones obtained using Scheimpflug tomography (Pentacam HR, Oculus). RESULTS: The study investigated 12 eyes of 12 patients. The anterior (120 MUm) stromal layer within the 0.0 to 2.0 mm and 2.0 to 6.0 mm concentric zones showed a significant elevation of mean densitometry 3 months post-surgery (P = 0.045; P = 0.015) compared to baseline. A mean stromal demarcation line was apparent at a depth of 203.00 MUm +/- 13.53 (SD). After accelerated CXL, no change in mean corrected distance visual acuity (LogMAR) was observed but a thinning of the cornea measured by a significant reduction in central pachymetry (MUm). CONCLUSION: Accelerated CXL results in an increase in corneal densitometry, particularly in the anterior stromal layer within the two central concentric zones (0.0 to 2.0 mm and 2.0 to 6.0 mm) of the cornea at 3 months postoperatively. The changes in corneal densitometry of the anterior stromal layer did not correlate with postoperative visual acuity or central pachymetry. PMID- 29582260 TI - Orbital apex syndrome secondary to optic nerve cysticercosis. AB - A 22-year-old male presented to us with complaints of sudden painful loss of vision in left eye 10 days ago along with inward deviation of the left eye. Best corrected visual acuity (BCVA) in right eye was 20/20 and 20/50 in left eye. Left eye showed limitation of abduction, a relative afferent pupillary defect, normal anterior segment with optic disc oedema. Contrast-enhanced MRI of the brain and orbit showed thickening of left optic nerve along with a cystic lesion near the orbital apex with a central iso- to hyperintense spot resembling a scolex. A diagnosis of left orbital apex syndrome secondary to optic nerve cysticercosis was made. Patient was treated with oral albendazole and intravenous corticosteroids for 3 days followed by oral corticosteroids. Ten weeks post treatment, his BCVA in the left eye improved to 20/20 and colour vision and visual fields improved. Pallor of the left optic disc was noted, and ocular motility improved completely. MRI after treatment showed a decreased thickness of left optic nerve with disappearance of the cystic lesion. PMID- 29582261 TI - Effects of different treatments on chemical and morphological features of eroded dentin. AB - To evaluate the treatment of eroded dentin (Sensodyne Repair & ProtectTM, Er:YAG laser and combinations). The occlusal surfaces of 25 third molars were sectioned 1.5 mm in thickness. After an erosion cycle (5 min in demineralizing solution + 3 h in remineralizing solution; six cycles a day for 8 days), the samples were divided into five groups (n = 5): (E) erosion - control; (ES) erosion + Sensodyne Repair & Protect (NovaMin); (EL) erosion + Er:YAG laser (40 mJ, 10 Hz, 0.4 W, 50 MUs, 3.1 J/cm2, 63 W/cm2); (ELS) erosion + Er:YAG laser + Sensodyne; and (ESL) erosion + Sensodyne + Er:YAG laser. Following storage in ultrapure water (37 degrees C/14 days), the Ca/P ratio was evaluated by EDXRF and the morphology surfaces examined in SEM. The percentage of exposed dentin tubules was calculated. One-way analysis of variance and Tukey's test at 5% were used to treat the data. The Ca/P ratio was higher in E and ES groups. More exposed dentin tubules were found in E group and less exposed tubules were found in the ES group (p < 0.0001). When the toothpaste and laser were combined, the number of occluded dentin tubules was higher when laser was performed first (ELS). A positive effect was found when the laser and toothpaste were combined. PMID- 29582262 TI - Distribution of heavy metals and associated human health risk in mine, agricultural and roadside soils at the largest chromite mine of India. AB - This study accessed the levels of Cd, Cr, Fe, Mn, Ni, Pb and Zn concentration in soils of different locations (mine, roadside, agricultural and control sites) of Sukinda chromite mine (the India's largest Chromite mine and listed among the world's ten most polluted regions). Geo-accumulation (Igeo) index indicates that the mine, agricultural and roadside soils are 'heavily to extremely contaminated' due to Cr, Ni, Pb and Cd, hence human residing/working in this region can have health hazards due to contaminated soil via different exposure pathways. The concentration of heavy metals (mg/kg) in mine site vary between 52.35 and 244.8 (Cr6+), 12,030.2 and 31,818.6 (Cr3+), 5460.4 and 8866.0 (Ni), 70.02 and 208.6 (Pb), 0.95 and 5.3 (Cd), 209.1 and 360.4 (Mn), 21,531.8 and 28,847 (Fe) and 221 and 349.3 (Zn). Fe, Cr6+, Cr3+ and Ni concentration in soil follows an order of mine site > road sites > agricultural lands > control forest sites. Principal component analysis and hierarchical cluster analysis indicate Cd, Cr, Fe, Ni and Pb as major pollutants in the region. Cancer Risk is 'high' in both adult (5.38E 04) and children (4.45E-04) in mining sites and 'low' to 'very low' in agricultural and road side soils. The hazard index for all the heavy metals in a mining areas is varied from 2.9 to 5.2 in adult and 2.8-5.1 in children, indicating 'high' to 'very high' non-cancer risk due to significant contribution of Ni, Pb and Cr6+ concentration (73, 11 and 10%, respectively). PMID- 29582263 TI - Heavy metal speciation, leaching and toxicity status of a tropical rain-fed river Damodar, India. AB - Speciations of metals were assessed in a tropical rain-fed river, flowing through the highly economically important part of the India. The pattern of distribution of heavy metals (Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn) were evaluated in water and sediment along with mineralogical characterization, changes with different water quality parameters and their respective health hazard to the local population along the Damodar River basin during pre-monsoon and post-monsoon seasons. The outcome of the speciation analysis using MINTEQ indicated that free metal ions, carbonate, chloride and sulfate ions were predominantly in anionic inorganic fractions, while in cationic inorganic fractions metal loads were negligible. Metals loads were higher in sediment phase than in the aqueous phase. The estimated values of Igeo in river sediment during both the seasons showed that most of the metals were found in the Igeo class 0-1 which represents unpolluted to moderately polluted sediment status. The result of partition coefficient indicated the strong retention capability of Cr, Pb, Co and Mn, while Cd, Zn, Cu and Ni have resilient mobility capacity. The mineralogical analysis of sediment samples indicated that in Damodar River, quartz, kaolinite and calcite minerals were dominantly present. The hazard index values of Cd, Co and Cr were > 1 in river water, which suggested potential health risk for the children. A combination of pragmatic, computational and statistical relationship between ionic species and fractions of metals represented a strong persuasion for identifying the alikeness among the different sites of the river. PMID- 29582264 TI - Association between skin lesion and arsenic concentration in hair by mixed bivariate model in chronic arsenic exposure. AB - Skin lesion is one of the important health hazards caused by high intake of arsenic through drinking water and diet, and the other hazards include several types of cancers (viz. skin, lung and urinary bladder), ischemic heart disease, hypertension, etc. Two most important biomarkers to measure arsenic intake in a human body are arsenic concentration in urine and hair. The primary interest of this paper is the association between skin lesion and arsenic concentration in hair for participants with chronic arsenic exposure from West Bengal, India, using bivariate regression model based on copula function. The result showed participants with high arsenic concentration in hair had higher incidence of developing skin lesion. Arsenic concentration in hair was significantly higher for the participants with an arsenic concentration in water > 10 mg/L. PMID- 29582265 TI - Source identification, environmental risk assessment and human health risks associated with toxic elements present in a coastal industrial environment, India. AB - This study investigated the source and contamination levels of toxic elements (Cd, Cr, As, Pb, Ni and Hg) present in a coastal environment, Paradip-an industrial hub of the east coast of India. The ecological risk assessment indices and human exposure models were used to evaluate the pollution status. Enrichment factor indicated that all the metal(loid)s found in the sediment are mostly derived from the anthropogenic source. According to the sediment quality quotient, 8.33% of sediments have crossed the ERM limit for Ni that can be fatal to biota. Meanwhile, 66.66, 41.66 and 8.33% of sediments have exceeded PEL range for Cr, Ni and As, respectively, that can register frequent lethal toxicity to benthic biota. As had the highest potential ecological harm coefficient (Erf > 80), and Hg had moderate ecological harm coefficient (40 < Erf < 80). Summarily, the sediment quality of this site is moderate to heavily toxic to benthic organisms. The concentration of toxic metals in seawater was below the permissible limit (CCC and CMC) set by USEPA indicating that water is relatively safer for free floating aquatic biota. The health risk index of toxic metal (loid)s present in soils of the residential sites has confirmed that there is a severe non-carcinogenic threat for children (HI child > 1) and a borderline carcinogenic risk for both adult and children. THQCr possesses highest non carcinogenic threat, which contributed approximately 50% to HI followed by THQAs. The contribution of carcinogenic risk of chromium (CRCr) to TCR is approximately 60%. Cr is the significant contaminant of this site that has highest health effects. Highest exposure risks were associated with ingestion pathway accounting for about 85% of the total for most of the elements.

PMID- 29582267 TI - Public Perception of Female Fertility: Initial Fertility, Peak Fertility, and Age Related Infertility Among U.S. Adults. AB - Perceptions of fertility are thought to impact reproductive behaviors, yet little is known about how lay people conceptualize the female fertility timeline. In this research, public perception of the female fertility timeline was assessed via a national survey of U.S. adults (N = 990) ranging in age from 18 to 89 years. Although there is no scientific consensus on the makeup of the female fertility timeline, results from this research indicate that the U.S. public posits fertility onset at (approximately) 13 years, peak fertility at 22, ideal first pregnancy age at 23, too late for pregnancy at 46, and infertility at 49. Regression analysis revealed that perceived peak fertility and ideal pregnancy age were positively correlated such that participants perceived the ideal pregnancy age as directly following peak fertility. Education was significantly related to fertility perceptions; those with more education perceived initial fertility to be lower and peak fertility and ideal pregnancy age to be higher. In other words, more highly educated individuals perceived fertility to manifest over a longer period of time as compared to individuals with less education. Black and Hispanic participants and participants with lower income perceived ideal first pregnancy age as significantly lower than did White participants and participants with higher income. These differences may suggest that the seeds of health disparities associated with phenomena such as adolescent pregnancy are lurking in fertility timeline perceptions. PMID- 29582268 TI - Effects of Sexual Arousal and Alcohol Cues on Acute Motivation for Alcohol. AB - Reward-related stimuli can induce motivation to obtain rewards both within and across domains. We tested within- and cross-domain effects of environmental context (mock bar vs. laboratory) and sexually arousing stimuli (pornography vs. nature film) on acute motivation for alcohol as measured by a state-based alcohol purchase task in 109 male and female college students. Our results showed significant effects of both sexual arousal and environmental context on acute motivation for alcohol. A limited subsample analysis (N = 84) revealed significant effects of both sexual arousal and environmental context conditions on elasticity. Consistent with hypotheses, the presence of either sex- or alcohol related cues increased acute motivation for alcohol and decreased sensitivity to costs of drinking. Furthermore, there was a significant video * laboratory condition interaction in the elasticity analysis. Our findings suggest that both sexually arousing stimuli and incidental environmental alcohol cues may significantly increase the effort one will expend to consume alcohol and thus the potential for risky drinking behavior. We believe this is the first experiment to use demand curves to present evidence of cross-domain effects of sexually arousing stimuli on acute motivation for alcohol. PMID- 29582269 TI - Sexual Probability Discounting: A Mechanism for Sexually Transmitted Infection Among Undergraduate Students. AB - Lack of condom use among youth is a major contributor to the spread of sexually transmitted infections (STIs) including HIV/AIDS, which has lifelong deleterious health consequences. College students (N = 262) completed the Sexual Probability Discounting Task in which participants reported their likelihood of condom use under various probabilities of contracting an STI. Each participant completed the task in regard to different STIs including HIV/AIDS and different partners. Results showed that the likelihood of condom-protected sex generally decreased as HIV/AIDS and other STI contraction became less probable. Moreover, condom protected sex likelihood was related to STI type (e.g., decreased condom protected sex in chlamydia relative to HIV/AIDS condition) and partner desirability (decreased condom-protected sex with more desirable partners). Results are the first to show that compared to other STIs, HIV/AIDS had the most influence on condom-protected sex. Results showed probability discounting contributed to lack of condom-protected sex and offers a novel framework for examining determinants of within-subject variability in condom use. PMID- 29582270 TI - Indications for salvage surgery during treatment for intracranial germ cell tumors. AB - This study retrospectively reviewed our single institute experience to clarify the optimal indication and timing of salvage surgery. Retrospective analysis of 159 consecutive cases with germ cell tumors identified 20 cases with salvage surgery. These cases were classified based on the radiological response to neoadjuvant treatment before salvage surgery into increase (growing group, five cases), no change (stable group, seven cases), and decrease (shrinkage group, eight cases) in tumor size. Changes in tumor markers, histological findings, and the pattern of failure after salvage surgery were reviewed. Growing teratoma syndrome (GTS) is defined as enlargement of tumor consisting of mature teratoma after chemotherapy with normalization of tumor markers. In growing group, two cases presented GTS, whereas other three cases did not fulfill the criteria for GTS. All cases in stable and shrinkage group had elevated levels of tumor markers at presentation and decreased levels after neoadjuvant treatment. Histologically, sparse components of mature teratoma with extensive fibrosis were found in cases with GTS and seven of eight cases in shrinkage group, whereas mature teratoma without fibrosis was found in six of seven cases in stable group. Six cases recurred after salvage surgery. We identified three factors as risks for recurrence after salvage surgery, as follows: (1) growing lesion which did not fulfill the criteria for GTS, (2) non-normalized level of tumor marker before salvage surgery, and (3) residual germinoma component. In conclusion, salvage surgery is recommended for patients with GTS, or with normalized tumor markers in stable or shrinkage group. PMID- 29582272 TI - [Tick-borne encephalitis].

PMID- 29582271 TI - Reduced hydroxymethylation characterizes medulloblastoma while TET and IDH genes are differentially expressed within molecular subgroups. AB - INTRODUCTION: Medulloblastoma (MB) is an embryonal tumour that originates from genetic deregulation of cerebellar developmental pathways and is classified into 4 molecular subgroups: SHH, WNT, group 3, and group 4. Hydroxymethylation levels progressively increases during cerebellum development suggesting a possibility of deregulation in MB pathogenesis. The aim of this study was to investigate global hydroxymethylation levels and changes in TET and IDH gene expression in MB samples compared to control cerebellum samples. METHODS: The methods utilized were qRT-PCR for gene expression, dot-blot and immunohistochemistry for global hydroxymethylation levels and sequencing for the investigation of IDH mutations. RESULTS: Our results show that global hydroxymethylation level was decreased in MB, and low 5hmC level was associated with the presence of metastasis. TET1 expression levels were decreased in the WNT subgroup, while TET3 expression levels were decreased in the SHH subgroup. Reduced TET3 expression levels were associated with the presence of events such as relapse and death. Higher expression of IDH1 was observed in MB group 3 samples, whereas no mutations were detected in exon 4 of IDH1 and IDH2. CONCLUSION: These findings suggest that reduction of global hydroxymethylation levels, an epigenetic event, may be important for MB development and/or maintenance, representing a possible target in this tumour and indicating a possible interaction of TET and IDH genes with the developmental pathways specifically activated in the MB subgroups. These genes could be specific targets and markers for each subgroup. PMID- 29582274 TI - [Herpes zoster]. PMID- 29582276 TI - ? PMID- 29582275 TI - [Rotten bones - no way]. PMID- 29582277 TI - ?

PMID- 29582318 TI - Clinical mimics: an emergency medicine focused review of pneumonia mimics. AB - Pneumonia is a common cause of morbidity and mortality in adults in the United States. While pneumonia classically presents with a fever, cough, and shortness of breath, the presentation can vary widely in adults. This review evaluates history and physical examination findings of pneumonia and several conditions that mimic pneumonia. Pneumonia is a potentially deadly disease. History and examination findings are variable in pneumonia, and many conditions mimic pneumonia. These conditions include pulmonary embolism, diffuse interstitial lung disease, endocarditis, vasculitis, diffuse alveolar hemorrhage, acute decompensated heart failure, tuberculosis, lung cancer, and acute respiratory distress syndrome. Emergency clinicians should assess the patient while resuscitation occurs. Early antibiotics and the diagnosis of pneumonia can improve outcomes. Key historical and physical examination findings may lead the clinician to consider other conditions that require immediate management. Using clinical evaluation and adjunctive imaging, these conditions can be diagnosed and treated. Knowledge of pneumonia mimics is vital for the care of patients with respiratory complaints. Pneumonia is common and may be deadly, and emergency clinicians must differentiate conditions that mimic pneumonia. Rapid evaluation and management may alleviate morbidity and mortality for each of these conditions. The history and physical examination, in addition to utilizing imaging modalities such as ultrasound and computed tomography, are vital in diagnosis of pneumonia mimics. PMID- 29582320 TI - Soft tissue sarcomas: new opportunity of treatment with PARP inhibitors? AB - BACKGROUND: Poly(ADP-ribose) polymerases (PARP) are a large family of enzymes involved in several cellular processes, including DNA single-strand break repair via the base-excision repair pathway. PARP inhibitors exert antitumor activity by both catalytic PARP inhibition and PARP-DNA trapping, moreover PARP inhibition represents a potential synthetic lethal approach against cancers with specific DNA-repair defects. Soft tissue sarcoma (STSs) are a heterogeneous group of mesenchymal tumors with locally destructive growth, high risk of recurrence and distant metastasis. OBJECTIVES: The purpuse of this review is to provide an overview of the main preclinical and clinical data on use of PARPi in STSs and of effect and safety of combination of PARPi with irradiation. RESULTS: Due to numerous genomic alterations in STSs, the DNA damage response pathway can offer an interesting target for biologic therapy. Preclinical and clinical studies showed promising results, with the most robust evidences of PARPi efficacy obtained on Ewing sarcoma bearing EWS-FLI1 or EWS-ERG genomic fusions. The activity of PARP inhibitors resulted potentiated by chemotherapy and radiation. Although mechanisms of synergisms are not completely known, combination of radiation therapy and PARP inhibitors exerts antitumor effect by accumulation of unrepaired DNA damage, arrest in G2/M, activity both on oxic and hypoxic cells, reoxygenation by effect on vessels and promotion of senescence. Early trials have shown a good tolerance profile. CONCLUSIONS: The use of PARP inhibitors in advanced stage STSs, alone or combined in multimodal treatments, is of great interest and warrants further investigations.

AB - PURPOSE: To compare the diagnostic performance of T1 high-resolution isotropic volume excitation (THRIVE) sequence with that of a standard protocol for direct shoulder magnetic resonance arthrography (MRA) for the diagnosis of superior labral anterior-to-posterior (SLAP) and Bankart lesions, using arthroscopy findings as a reference standard. MATERIALS AND METHODS: We retrospectively studied 84 patients who underwent direct shoulder 3T MRA using THRIVE and two dimensional three-plane proton-density fat-suppressed (2D-PD-FS) sequences. One reviewer evaluated the contrast-to-noise ratio (CNR) as a quantitative image quality. Other two reviewers independently evaluated the subjective image noise, image sharpness, and radiologic diagnosis as qualitative image quality. Arthroscopic surgical findings were considered the reference standard. Wilcoxon rank sum, Chi-square/Fisher's exact, and DeLong's tests, as well as intraclass correlation coefficients (ICCs) were used to evaluate differences between THRIVE and 2D-PD-FS images. RESULTS: THRIVE images had significantly higher CNR (p < 0.001), and subjective ratings of image noise (p = 0.009) and sharpness (p = 0.039) than 2D-PD-FS images (p < 0.001). THRIVE images had similar (p >= 0.18) diagnostic performance (sensitivity, 93.0-97.2%; specificity, 95.8-100%; accuracy, 95.2-97.6%) for the diagnosis of SLAP and Bankart lesions with excellent agreement (ICC = 0.898-0.942) when compared to 2D-PD-FS images (sensitivity, 86.1-91.7%; specificity, 93.8-95.8%; accuracy, 90.5-92.9%; agreement, ICC = 0.782-0.858). The scan time was reduced by 69% for THRIVE sequence compared to 2D-PD-FS sequence (2 min 40 s vs. 8 min 40 s). CONCLUSION: The THRIVE sequence may be helpful in the diagnosis of SLAP and Bankart lesions, and may be routinely used during direct shoulder 3T MRA.

AB - This study investigated a new biochar produced from vinegar residue that could be used to remediate cadmium (Cd)-contaminated water and soil. Aqueous solution adsorption and soil incubation experiments were performed to investigate whether a biochar prepared at 700 degrees C from vinegar residue could efficiently adsorb and/or stabilize Cd in water and soil. In the aqueous solution adsorption experiment, the Cd adsorption process was best fitted by the pseudo-second-order kinetic and Freundlich isotherm models. If the optimum parameters were used, i.e., pH 5 or higher, a biochar dosage of 12 g L-1, a 10 mg L-1 Cd initial concentration, and 15-min equilibrium time, at 25 degrees C, then Cd removal could reach about 100%. The soil incubation experiment evaluated the biochar effects at four different application rates (1, 2, 5, and 10% w/w) and three Cd contamination rates (0.5, 1, and 2.5 mg kg-1) on soil properties and Cd fractionation. Soil pH and organic matter increased after adding biochar, especially at the 10% application rate. At Cd pollution levels of 1.0 or 2.5 mg kg-1, a 10% biochar application rate was most effective. At 0.5 mg Cd kg-1 soil, a 5% biochar application rate was most efficient at transforming the acid extractable and easily reducible Cd fractions to oxidizable and residual Cd. The results from this study demonstrated that biochar made from vinegar residue could be a new and promising alternative biomass-derived material for Cd remediation in water and soil. PMID- 29582323 TI - Assessment of biotoxicity of Cu nanoparticles with respect to probiotic strains of microorganisms and representatives of the normal flora of the intestine of broiler chickens. AB - Copper nanoparticle Cu (d = 55 +/- 15 nm) and CuO nanoparticles (d = 90 +/- 10 nm) were used in the studies (OOO Platina, Russia). Using the method of pure cultures, we extracted Lactobacillus, Enterococcus, and Enterobacterium from the intestines of broilers. Additionally, strains of Bacillus subtilis 10641 and Bifidobacterium were involved in probiotic strains. The data obtained in the course of the study testify to the insignificant biotoxicity of copper nanoparticles with respect to representatives of the genera Lactobacillus (30 to 15 MUg/ml) and Bifidobacterium (30 MUg/ml), with the most sensitive bacteria being the genus Lactobacillus, for which a concentration of 7.5 MUg/ml was subinhibitory. The second stage was the study using method of agar wells. In the course of the experiment, we obtained results confirming the data of the research by the serial dilution method. In this case, as in the first case, the data indicate the insignificant biotoxicity of copper nanoparticles in relation to representatives of the genera Lactobacillus and Bifidobacterium. We have studied the bioaccumulating ability of microorganisms of the studied metals. In all the studies carried out, as in the first series of experiments, representatives of the genera Lactobacillus and Bifidobacterium with the lowest bioaccumulative ability were the most sensitive to copper nanoparticles and were 3.1 and 8.2%, respectively. The use of nanoparticles as a component of the fodder additive in small concentrations does not adversely affect not only the probiotic strains, but also the main representatives of the normoflora (Lactobacillus, Enterococcus, and Enterobacterium) of the poultry, the positive effect of the copper nanoparticles being directly related to low level of dissociation of nanoparticles, since biologically active ions will be released much more slowly, thereby creating a prolonged effect of exposure. PMID- 29582324 TI - Caffeine levels as a predictor of Human mastadenovirus presence in surface waters a case study in the Sinos River basin-Brazil. AB - The presence of caffeine in environmental water samples is almost entirely human related, given that there are virtually no industrial or agricultural releases. Caffeine has already been proposed as an anthropogenic marker for wastewater contamination of surface waters. The aim of this study was to evaluate if caffeine concentrations in water can be a predictor of virological and bacteriological contamination. Water samples were taken at three sampling sites from urban water streams from the hydrographic basin of the Sinos River (Brazil) monthly in the period of May 9th, 2016 to April 11th, 2017 (n = 36). Concentrations of Human mastadenovirus (HAdV-F and HAdV-C), fecal coliforms, and caffeine were measured in all collected samples. Concentrations of caffeine in water were strongly correlated with HAdV-F (rs = 0.704, p = 0.000). This study, for the first time, characterized caffeine concentrations in water as predictors of virus presence, with cut-off values presenting 92.9% specificity and 95.5% sensitivity for HAdV-F and 66.7% specificity and 80% sensitivity for HAdV-C. Considering its marked chemical stability and ease of quantification, caffeine concentrations can be used as a comprehensive marker of human contamination of water resources, also being predictive of bacteriological and virological concentrations. PMID- 29582325 TI - Protective effect of grape or apple juices in bone tissue of rats exposed to cadmium: role of RUNX-2 and RANK/L expression. AB - The aim of this study was to investigate if grape or apple juices are able to protect bone tissue of rats exposed to cadmium. For this purpose, histopathological analysis and immunohistochemistry for RUNX-2 and RANK-L were investigated in this setting. A total of 20 adult Wistar rats were distributed into four groups (n = 5), as follows: control group, cadmium group, cadmium and grape juice group, and Cadmium and apple juice group. Control group received a single intraperitoneal (i.p.) water injection. Cadmium group received a single i.p. injection of cadmium chloride (1.2 mg/kg body weight) diluted in water. Cadmium and grape juice and cadmium and apple juice groups received a single i.p. injection of cadmium chloride (1.2 mg/kg body), and after 15 days, the rats were treated with grape or apple juices for 15 days, by gavage. All animals were euthanized 30 days after the beginning of experiment. Histopathological analysis in rat femur revealed extensive bone loss in rats intoxicated with cadmium. Grape or apple juices were able to increase bone formation. Cadmium inhibited RUNX-2 immunoexpression whereas cadmium increased RANK-L immunoexpression in rat bone cells. Grape or apple juices increased RUNX-2 and decreased RANK-L immunoexpression after cadmium intoxication. Taken together, our results demonstrate that grape or apple juices are able to exert therapeutic activity following cadmium intoxication in rat bone tissue as result of stimulatory effect of bone formation by RUNX-2 upregulation and RANK-L downregulation. PMID- 29582326 TI - Using carbonized low-cost materials for removal of chemicals of environmental concern from water. AB - Adsorption on low-cost biochars would increase the affordability and availability of water treatment in, for example, developing countries. The aim of this study was to identify the precursor materials and hydrochar surface properties that yield efficient removal of compounds of environmental concern (CEC). We determined the adsorption kinetics of a mixture containing ten CECs (octhilinone, triclosan, trimethoprim, sulfamethoxasole, ciprofloxacin, diclofenac, paracetamol, diphenhydramine, fluconazole, and bisphenol A) to hydrochars prepared from agricultural waste (including tomato- and olive-press wastes, rice husks, and horse manure). The surface characteristics of the hydrochars were evaluated via diffuse reflectance infrared spectroscopy (DRIFTS), X-ray photoelectron spectroscopy (XPS), and N2-adsorption. Kinetic adsorption tests revealed that removal efficiencies varied substantially among different materials. Similarly, surface analysis revealed differences among the studied hydrochars and the degree of changes that the materials undergo during carbonization. According to the DRIFTS data, compared with the least efficient adsorbent materials, the most efficient hydrochars underwent more substantial changes during carbonization. PMID- 29582316 TI - Major adverse cardiovascular events in non-valvular atrial fibrillation with chronic obstructive pulmonary disease: the ARAPACIS study. AB - Chronic obstructive pulmonary disease (COPD) increases the risk of mortality in non-valvular atrial fibrillation (NVAF) patients. Data on the relationship of COPD to major cardiovascular events (MACE) in AF have not been defined. The aim of the study is to assess the predictive value of COPD on incident MACE in NVAF patients over a 3-year follow-up. In the Atrial Fibrillation Registry for Ankle Brachial Index Prevalence Assessment-Collaborative Italian Study (ARAPACIS) cohort, we evaluate the impact of COPD on the following clinical endpoints: MACE (including vascular death, fatal/non-fatal MI and stroke/TIA), cardiovascular (CV) death and all-cause mortality. Among 2027 NVAF patients, patients with COPD (9%) are more commonly male, elderly and at higher thromboembolic risk. During a median 36.0 months follow-up, 186 patients experienced MACE: vascular death (n = 72), MI (n = 57), stroke/TIA (n = 57). All major outcomes (including stroke/TIA, MI, vascular death, and all-cause death) are centrally adjudicated. Kaplan-Meier curves show that NVAF patients with COPD are at higher risk for MACE (p < 0.001), CV death (p < 0.001) and all-cause death (p < 0.001). On Cox proportional hazard analysis, COPD is an independent predictor of MACE (Hazard ratio [HR] 1.77, 95% Confidence Intervals [CI] 1.20-2.61; p = 0.004), CV death (HR 2.73, 95% CI 1.76 4.23; p < 0.0001) and all-cause death (HR 2.16, 95% CI 1.48-3.16; p < 0.0001). COPD is an independent predictor of MACE, CV death and all-cause death during a long-term follow-up of NVAF patients. PMID- 29582327 TI - Assessment of the effects of different tree species on urban microclimate. AB - Trees in urban areas are important for their ecological functions in addition to their esthetic characteristics. Trees provide positive effects on urban microclimate by canopy, reflection, and transpiration activities; therefore, they help to decline formation of heat island. The objective of this study was to determine thermal effects of 15 different tree types: 4 coniferous and 11 deciduous species commonly found in the city of Erzurum located at the northeastern part of Turkey. The relationships between sky view factor and surface temperature regarding the differences in leaf density and tree species. In August 2016, the surface temperature of trees was measured using a thermal camera at 10:00 am and 4:00 pm hours. Sky view factor (SVF) was obtained by fisheye photos and physiologically characteristics of trees were determined. In all trees while the surface temperature was 20.1 degrees C at 10:00 am, it was 23.4 degrees C at 4:00 pm. Among the deciduous tree species, Betula verrucosa Ehrh. and Robinia pseudoacacia "Umbracuifera" had the lowest surface temperature; however, Abies concolor (Gord. & Glen.) had the lowest surface temperature among the coniferous tree species. The results indicated that the surface temperatures of different tree species varied considerably, and the SVF value had a significant effect on tree surface temperatures. However, it was obtained that the leaf types had no statistically significant effect on tree surface temperature. PMID- 29582328 TI - Effects of exogenous sulfur on growth and Cd uptake in Chinese cabbage (Brassica campestris spp. pekinensis) in Cd-contaminated soil. AB - Soil pollution with heavy metals has many adverse effects on ecosystem health as well as food security. A pot experiment was performed to investigate the effects of different valence states of exogenous sulfur (S) on the uptake of cadmium (Cd) in Chinese cabbage in Cd-contaminated soil. The results showed that S significantly promoted plant growth in Chinese cabbage, with the following order of magnitude for the different S treatments: sodium sulfite (Na2SO3) > sodium sulfate (Na2SO4) > powdered sulfur (S0). Additionally, enzyme activity and the content of reductive substances in the leaves markedly increased, while malondialdehyde content significantly decreased; hence, S observably enhanced the ability of Chinese cabbage to tolerate Cd stress. S0 significantly reduced soil pH, thus increasing the mobility and bioavailability of Cd in the soil, while Na2SO3 increased soil pH, and Na2SO4 had no effect on soil pH. The acid-soluble and oxidizable fractions of Cd in soil increased with the S0 treatment. The applied Na2SO3 and Na2SO4 both increased the residual fraction of Cd in the soil, but they reduced the amount of the acid-extractable, reducible, and oxidizable Cd. The results showed that compared with S0, the Na2SO3 and Na2SO4 treatments decreased the acid-extractable Cd concentrations by 6.3 and 4%, respectively, in the most contaminated soil. In conclusion, the influence of S on the bioavailability and speciation of Cd varied not only with the soil Cd content but also with the application rate and S valence state. PMID- 29582329 TI - Distribution and hydrogeochemical behavior of arsenic enriched groundwater in the sedimentary aquifer comparison between Datong Basin (China) and Kushtia District (Bangladesh). AB - A prompt growth in research on arsenic occurrence and behavior in the environment has occurred over the last decade or so. High arsenic (As) in groundwater has become a major global concern due to its widespread occurrence. A comparative hydrogeochemical study was performed on the occurrence of high As groundwater in Datong Basin, China, and Kushtia District, Bangladesh. A total of 132 groundwater samples (83 from Datong Basin and 49 from Kushtia District) were collected to analyze the major hydrogeochemical components and trace elements in groundwater of both areas. Factor analysis (FA) was applied on the hydrochemical data to identify the major hydrogeochemical processes in sedimentary aquifers. High As groundwater was observed in the low-lying central parts of Datong Basin, which are composed of the Holocene alluvial and lacustrine aquifers. The elevated As concentrations ranged from 0.31 to 452 MUg/L and distributed in depths between 20 and 45 m. As-enriched groundwater is mainly Na-HCO3 type water and characterized by higher pH value, high Na+, low Ca2+, SO42-, and NO3- along with moderate TDS. The alkaline and reducing subsurface environment facilitate the leaching of As in sedimentary aquifers. The release and distribution of As in aquifers are resulted from the reduction of As-carrying crystalline iron (Fe) oxide/hydroxides and oxidation of organic matter. The aquifers of Kushtia District, Bangladesh, are unconsolidated, alluvial in nature, and developed from Holocene floodplain and Pleistocene deposits. High As (6.04-590.7 MUg/L) groundwater occurs mainly in shallow aquifers. The Ca-HCO3 type groundwater is distinguished by circum-neutral pH, medium-high EC, high HCO3-, and low content of NO3-, SO42-, K+, and Cl-. The reductive suspension of MnOOH increases the dissolved As loads and redox responsive elements such as SO42- and pyrite oxidation act as the main mechanisms for As release in groundwater. As is mobilized by anaerobic leakage from the brown-clay and gray-sand into the sediment. Infiltration from irrigation return and surface wash water are the potential factors that remobilize As. The weak loading of Fe suggests that the release of Fe and As is decoupled in sedimentary aquifers of Kushtia District. PMID- 29582330 TI - Screening of groundwater remedial alternatives for brownfield sites: a comprehensive method integrated MCDA with numerical simulation. AB - Brownfield sites pollution and remediation is an urgent environmental issue worldwide. The screening and assessment of remedial alternatives is especially complex owing to its multiple criteria that involves technique, economy, and policy. To help the decision-makers selecting the remedial alternatives efficiently, the criteria framework conducted by the U.S. EPA is improved and a comprehensive method that integrates multiple criteria decision analysis (MCDA) with numerical simulation is conducted in this paper. The criteria framework is modified and classified into three categories: qualitative, semi-quantitative, and quantitative criteria, MCDA method, AHP-PROMETHEE (analytical hierarchy process-preference ranking organization method for enrichment evaluation) is used to determine the priority ranking of the remedial alternatives and the solute transport simulation is conducted to assess the remedial efficiency. A case study was present to demonstrate the screening method in a brownfield site in Cangzhou, northern China. The results show that the systematic method provides a reliable way to quantify the priority of the remedial alternatives. PMID- 29582331 TI - Occurrence and toxicological assessment of polycyclic aromatic hydrocarbons (PAHs) in marine sediments under mussel farming influence. AB - The use of marine resources for mussel culture has become increasingly important, particularly on the European Atlantic coast and notably in the Galician Rias in the northwest of Spain. Despite its importance, there is a lack of research and analysis in this area and of the potential problems that it could cause to the environment. This paper details the findings of a study that aimed to find the probable environmental impact of mussel culture activities and to evaluate the polycyclic aromatic hydrocarbon (PAH) content derived from this activity. The Ria de Arousa, where you can find over 70% of all installed rafts in Galicia, was selected for the present study, and nearly 40 marine sediment samples were collected there. The sediments were extracted by ASE (accelerated solvent extraction) procedure, and the quantification of PAHs was performed using gas chromatography coupled to mass spectrometry (GC-MS), with the aid of deuterated PAH internal standards. The total concentration of parental PAHs ranged from 11.66 to 30,272-ng g-1 dry weight (d.w.), with a mean value of 3907-ng g-1 d.w.; the concentration of alkyl PAHs varied from 3.72 to 1187-ng g-1 d.w., with a mean value of 205.1-ng g-1 d.w. Compositional patterns, principal component analysis (PCA) and hieratical cluster association (HCA) yielded a sediment classification where the mussel raft impact is pointed out. PAH ratios indicated a predominance of combustion sources, except in two samples, located in small harbors. Only one station showed total potential carcinogenic PAH values in the range that would frequently cause negative biological effects, and the toxic equivalent concentrations based on BaP equivalents identified another ten positions where biological effects would occur occasionally. PMID- 29582332 TI - The copper complexation ability of a synthetic humic-like acid formed by an abiotic humification process and the effect of experimental factors on its copper complexation ability. AB - Humic acids have an important impact on the distribution, toxicity, and bioavailability of hazardous metals in the environment. In this study, a synthetic humic-like acid (SHLA) was prepared by an abiotic humification process using catechol and glycine as humic precursors and a MnO2 catalyst. The effect of physico-chemical conditions (ionic strength from 0.01 to 0.5 M NaNO3, pH from 4 to 8, temperature from 25 to 45 degrees C, and humic acid concentration from 5 to 100 mg/L) on the complexation ability of SHLA for Cu2+ were investigated. A commercial humic acid (CHA, CAS: 1415-93-6) from Sigma-Aldrich was also studied for comparison. The results showed that for pH 4 to 8, the conditional stability constants (log K) of SHLA and CHA were in the range 5.63-8.62 and 4.87-6.23, respectively, and complexation capacities (CC) were 1.34-2.61 and 1.42-2.31 mmol/g, respectively. The Cu complexation ability of SHLA was higher than that of the CHA due to its higher number of acidic functional groups (SHLA 19.19 mmol/g; CHA 3.87 mmol/g), extent of humification and aromaticity (AL/AR: 0.333 (SHLA); 1.554 (CHA)), and O-alkyl functional groups (SHLA 15.56%; CHA 3.45%). The log K and complexation efficiency (fraction of metal bound to SHLA) of SHLA were higher at higher pH, lower ionic strength, higher temperature, and higher SHLA concentration. Overall, SHLA was a good and promising complexation agent for copper in both soil washing of copper contaminated soil and the treatment of copper-containing wastewater. PMID- 29582333 TI - Influence of post-transplant mucosal-associated invariant T cell recovery on the development of acute graft-versus-host disease in allogeneic bone marrow transplantation. AB - Mucosal-associated invariant T (MAIT) and invariant natural killer T (iNKT) cells are T cell subpopulations that possess innate-like properties. We examined the impact of post-hematopoietic stem cell transplantation (HSCT) MAIT and iNKT cell recovery on the clinical outcomes of 69 patients who underwent allogeneic HSCT at Kyoto University Hospital. Multivariate analyses identified the absolute number of MAIT cells (< 0.48/MUL on day 60 post-HSCT) as the sole independent risk factor for grade I-IV and grade II-IV acute graft-versus-host disease (aGVHD) among patients who underwent bone marrow transplantation; no correlation was observed between post-HSCT iNKT cell recovery and the development of aGVHD. Six of the 15 patients in the MAIThigh (>= 0.48/MUL) group developed aGVHD, five within the first 30 days post HSCT. In contrast, 13 of the 15 patients in the MAITlow (< 0.48/MUL) group developed aGVHD, seven after day 30 post HSCT. The overall survival of the MAITlow group was slightly shorter than that of the MAIThigh group. Thus, the post-HSCT recovery of MAIT cells is closely related to the development of delayed onset aGVHD and the outcome of post-HSCT, suggesting its utility for identifying a subset of patients that requires more prolonged and/or intense GVHD prophylaxis. PMID- 29582334 TI - Acquired hemophilia A associated with autoimmune pancreatitis with serum IgG4 elevation. AB - A case of acquired hemophilia A (AHA) that developed in a patient with autoimmune pancreatitis (AIP) is presented. A 64-year-old woman was diagnosed with AIP in 2007. The symptoms resolved with prednisolone (PSL). Although the dose of PSL was tapered to 7.5 mg/day for maintenance, serum IgG4 levels remained high. She suddenly presented with subcutaneous bleeding in 2015. Her activated partial thromboplastin time was prolonged (80.0 s). A mixing test showed an inhibitor pattern, factor VIII (FVIII) activity was less than 1%, and FVIII inhibitor was 290 BU/mL. She was diagnosed with AHA. Her serum IgG4 was elevated to 133 mg/dL. She was treated first with PSL alone, but she developed bladder tamponade. Cyclophosphamide and activated prothrombin complex concentrate were combined with PSL. She then achieved hemostasis, and FVIII inhibitor disappeared. FVIII inhibitor had been detected since PSL was tapered and AHA recurred two months later. An enzyme-linked immunosorbent assay showed that the inhibitor was mainly IgG4 and IgG1. This case suggests that elevation of IgG4 may be associated with the development of both AHA and AIP. PMID- 29582335 TI - Influence of Religious and Spiritual Elements on Adherence to Pharmacological Treatment. AB - The objective of this study is to know the influence of religious/spiritual elements on the adherence to pharmacological therapy. The descriptors used for this literature review were "medicine, medication, drug, or treatment," "adherence to treatment," and "religion or spirituality or faith or prayer" in different databases (CINAHL, PsycINFO, PubMed). Finally, 23 articles were selected. Articles available in full text, published between 2010 and 2017, in English or Spanish were included. The results showed that some studies relate positively the R/S and therapeutic adherence, but others determine an opposite or even mixed effect, mainly addressing pathologies such as HIV and other chronic diseases. The influence of religiosity/spirituality on therapeutic adherence requires that health professionals acquire sensitivity and competence to address these issues with their patients. PMID- 29582337 TI - Longitudinal score prediction for Alzheimer's disease based on ensemble correntropy and spatial-temporal constraint. AB - Neuroimaging data has been widely used to predict clinical scores for automatic diagnosis of Alzheimer's disease (AD). For accurate clinical score prediction, one of the major challenges is high feature dimension of the imaging data. To address this issue, this paper presents an effective framework using a novel feature selection model via sparse learning. In contrast to previous approaches focusing on a single time point, this framework uses information at multiple time points. Specifically, a regularized correntropy with the spatial-temporal constraint is used to reduce the adverse effect of noise and outliers, and promote consistent and robust selection of features by exploring data characteristics. Furthermore, ensemble learning of support vector regression (SVR) is exploited to accurately predict AD scores based on the selected features. The proposed approach is extensively evaluated on the Alzheimer's disease neuroimaging initiative (ADNI) dataset. Our experiments demonstrate that the proposed approach not only achieves promising regression accuracy, but also successfully recognizes disease-related biomarkers. PMID- 29582338 TI - Health-related quality of life in end-stage renal disease patients: the effects of starting dialysis in the first year after the transition period. AB - BACKGROUND/AIMS: Prevalent dialysis patients have low scores of health-related quality of life (HRQOL) which are associated with increased risk of hospitalization and mortality. Also in CKD-5 non-dialysis patients, HRQOL scores seem to be lower as compared with the general population. This study firstly aimed to compare HRQOL between CKD-5 non-dialysis and prevalent dialysis patients in a cross-sectional analysis and to assess longitudinal changes over 1 year after the dialysis initiation. Secondly, the correlation between HRQOL and physical activity (PA) was explored. METHODS: Cross-sectional 44 CKD-5 non dialysis, 29 prevalent dialysis, and 20 healthy controls were included. HRQOL was measured by Short Form-36 questionnaires to measure physical and mental domains of health expressed by the physical component summary (PCS) and mental component summary (MCS) scores. PA was measured by a SenseWearTM pro3. Longitudinally, HRQOL was assessed in 38 CKD-5 non-dialysis patients (who were also part of the cross-sectional analysis), before dialysis initiation until 1 year after dialysis initiation. RESULTS: PCS scores were significantly lower both in CKD-5 non dialysis patients and in prevalent dialysis patients as compared with healthy controls (p < 0.001). MCS scores were significantly lower in both CKD-5 non dialysis patients (p = 0.003), and in dialysis patients (p = 0.022), as compared with healthy controls. HRQOL scores did not change significantly from the CKD-5 non-dialysis phase into the first year after dialysis initiation. PA was significantly related to PCS in both CKD-5 non-dialysis patients (r = 0.580; p < 0.001), and dialysis patients (r = 0.476; p = 0.009). CONCLUSIONS: HRQOL is already low in the CKD-5 non-dialysis phase. In the first year after dialysis initiation, HRQOL did not change significantly. Given the correlation between PCS score and PA, physical activity programs may be potential tools to improve HRQOL in both CKD-5 non-dialysis as well as in prevalent dialysis patients. PMID- 29582339 TI - Prevalence of pulmonary hypertension in patients with chronic kidney disease without dialysis: a meta-analysis. AB - PURPOSE: Recent epidemiological evidence attempts to demonstrate the risk of pulmonary hypertension (PH) among patients with chronic kidney disease (CKD) without dialysis, but prevalence estimates of PH in CKD without dialysis vary widely in the existing studies. This meta-analysis was to summarize the point prevalence of PH in adults with CKD without dialysis. METHODS: PubMed, EMBASE, the Cochrane Collaboration, and the reference lists of relevant articles were searched to identify eligible studies. We used a random-effect meta-analysis model to estimate the prevalence of PH. Associations were tested in subgroups and meta-regression analyses. We also performed sensitivity analyses and assessments of publishing bias. RESULTS: Twenty-one observational studies (n = 8012 participants) were included in this meta-analysis. The result of analysis in random-effect model showed that the pooled prevalence was 32% (95% CI 23-42%), with significant heterogeneity between these studies (I2 = 98%, P < 0.01). Stratified analyses found that the study design, region, sample size, year of publication, and definition of PH based on PASP >= 35 mmHg may explain the variation between studies. Sensitivity analysis further demonstrated the results to be robust. There was no evidence of publication bias. CONCLUSIONS: PH is highly prevalent in patients with CKD without dialysis. Owing to the high heterogeneity, future well-designed and large prospective studies are encouraged to confirm the findings and definitively clarify the potential biological mechanisms.

AB - A cross-sectional study was conducted among 308 lactating camels selected from 15 herds from three different camel milk clusters in Isiolo County, Kenya, to determine prevalence of bovine and avian tuberculosis using Single Comparative Intradermal Tuberculin Skin test. Seventy-five (75) questionnaires were administered to pastoralists/herders, and focus group discussions were conducted among 3-5 pastoralists/herders selected from each camel herd to collect information on camel husbandry and health management practices and knowledge on tuberculosis in livestock and wildlife. An overall prevalence of bovine and avian reactors was 3.57 and 18.18%, respectively, with bovine and avian reactors for different clusters being 2.38, 3.82, and 4.48% and 25, 17.2, and 11.94%, respectively. There was significant difference (p < 0.05) in prevalence of bovine and avian reactors between different clusters. There was a negative correction (r = -0.1399) between herd size and bovine reactors, while there was a positive correlation (r = 0.0445) between herd size and avian reactors. The respondents indicated that camel herds are exposed to several risk factors like close contact with other herds or livestock or wildlife during grazing and at watering points. Pastoralists have poor knowledge on mode of infection and transmission of bovine or avian tuberculosis. The high prevalence of bovine and avian reactors and pastoralists' poor knowledge on mode of transmission signify potential risk to public health.

AB - The objective of this experiment was to investigate the influence of ground date seed (GDS) on intake, digestibility, and milk yield and milk fatty acid (FA) composition of lactating Holstein cows. The experimental design was a 4 * 4 replicated Latin square with eight lactating dairy cows with an average milk production of 35.5 +/- 1.5 kg and 75 +/- 5 days in milk (DIM). Dairy cows were fed one of the four treatments contained 0, 2, 4, and 6% of diet dry matter (DM) GDS in replacement of wheat bran. All diets contained the same amount of forages (alfalfa hay and corn silage). Dietary treatments had no effect on DM intake (DMI), total tract apparent digestibility, milk yield, and milk composition. Increasing GDS linearly decreased concentration of C13:0 and increased cis-9 C14:1 and trans-11 C18:1 (vaccenic acid) (P < 0.05). A linear tendency for more C16:1 content in milk fat was observed with increasing GDS (P = 0.06). Feeding GDS resulted in a linear decrease (P < 0.01) in saturated FA (SFA) but increased milk fat monounsaturated FA (MUFA) and trans FA (TFA) (P < 0.05). Therefore, low levels of GDS (up to 6%) in the diet of Holstein dairy cows can beneficially modify milk FA composition without any adverse effects on intake, digestibility, and milk yield.

AB - A shortage in human resources for health is a growing crisis that has led to an inability to provide adequate health services to impoverished populations. By "task-shifting", health systems can delegate certain activities, such as health promotion and referral, to trained community members to help fill the human resource gap. An effective community health agent program can improve maternal and child health and overall effectiveness of rural health systems. Such a program is most effective when the community health agents receive supervision and evaluation of their performance. There is a shortage of literature that provides instruction and example on how to conduct a performance evaluation in the developing world to improve maternal and child health outcomes. The current study provides a case study of a performance evaluation in the Amazon region of Peru and how the findings can be used to make program adjustments. A set of instruments to measure the performance of CHWs was adapted from the literature and then implemented in the field. The instruments were used to measure the quality of home visits by the CHWs, their knowledge of the health topics, and structural activities. Three communities with an active CHW program in Loreto, Peru were chosen to receive the evaluation. All CHWs in the communities were evaluated. The scores from the evaluation were compared internally to identify strengths and weaknesses of the program and within the population of CHWs. The evaluation was completed on 52 home visits and 27 CHWs in three communities. The CHWs were found to be most effective at creating good relationships with caregivers and delivering health messages, and least effective at interacting with the child during the home visit and using material to deliver health messages. The evaluation instruments were well suited for the CHW program that utilizes home visits to teach about child health and development. PMID- 29582344 TI - TSH evaluation in hypothyroid patients assuming liquid levothyroxine at breakfast or 30 min before breakfast. AB - PURPOSE: To compare TSH levels of hypothyroid patients treated with liquid LT4 at breakfast or 30 min before breakfast. PATIENTS AND METHODS: Subjects, aged 18-75 years old, were eligible if they presented hypothyroidism, due to Hashimoto's thyroiditis or after thyroidectomy for proven benign goiter. Seven hundred ninety eight patients were recruited and enrolled in the study. Thirty-seven subjects withdrew from the trial. A total of 761 patients (mean age 46.2 +/- 10.8 years) completed the study. The starting dose of LT4 was determined through clinical judgment, taking into account TSH levels, estimated residual thyroid function, age, body weight and comorbidities. All patients underwent TSH, fT4, and fT3 evaluation to verify achievement of euthyroidism with their initial fasting state assumption of LT4 after 8 weeks of therapy. If euthyroidism was not achieved, an appropriately adjusted LT4 dose was administered for 8 weeks, after which thyroid function parameters were checked again. If euthyroidism was achieved, the patients were asked to take LT4 at breakfast and hormone levels were checked again after 6 months. RESULTS: At the end of the study period, no significant differences in serum TSH level were observed whether LT4 was ingested at breakfast or 30 min prior in a fasting state: 2.61 +/- 1.79 vs. 2.54 +/- 1.86 mIU/L, respectively (p = 0.455). CONCLUSIONS: This study confirms in a large set of patients that a liquid LT4 formulation can be taken directly at breakfast and potentially improve therapeutic compliance. PMID- 29582345 TI - Absence of cellular damage in tropical newly hatched sharks (Chiloscyllium plagiosum) under ocean acidification conditions. AB - Sharks have maintained a key role in marine food webs for 400 million years and across varying physicochemical contexts, suggesting plasticity to environmental change. In this study, we investigated the biochemical effects of ocean acidification (OA) levels predicted for 2100 (pCO2 ~ 900 MUatm) on newly hatched tropical whitespotted bamboo sharks (Chiloscyllium plagiosum). Specifically, we measured lipid, protein, and DNA damage levels, as well as changes in the activity of antioxidant enzymes and non-enzymatic ROS scavengers in juvenile sharks exposed to elevated CO2 for 50 days following hatching. Moreover, we also assessed the secondary oxidative stress response, i.e., heat shock response and ubiquitin levels. Newly hatched sharks appear to cope with OA-related stress through a range of tissue-specific biochemical strategies, specifically through the action of antioxidant enzymatic compounds. Our findings suggest that ROS scavenging molecules, rather than complex enzymatic proteins, provide an effective defense mechanism in dealing with OA-elicited ROS formation. We argue that sharks' ancient antioxidant system, strongly based on non-enzymatic antioxidants (e.g., urea), may provide them with resilience towards OA, potentially beyond the tolerance of more recently evolved species, i.e., teleosts. Nevertheless, previous research has provided evidence of detrimental effects of OA (interacting with other climate-related stressors) on some aspects of shark biology. Moreover, given that long-term acclimation and adaptive potential to rapid environmental changes are yet experimentally unaccounted for, future research is warranted to accurately predict shark physiological performance under future ocean conditions. PMID- 29582346 TI - Breast screening in symptomatic women over 35 years of age: improvements in service efficiency. AB - INTRODUCTION: The rationalization of cancer services in Ireland saw all women with symptomatic breast problems referred to one of the eight regional cancer centers. A pilot triaging system was introduced in St Vincent's University Hospital to streamline these services. Women over 35 years who do not meet urgent referral criteria are referred for a mammogram prior to a clinic appointment ("image first"). The aim of this study was to retrospectively determine the recall rates, biopsy rates, and rate of breast cancer identification within this cohort of patients. This was compared to a screening population of patients. METHODS: Patients triaged into the "image first" group within a one-year period were identified. Results of the initial mammogram, further imaging and subsequent biopsies were recorded. Data relating to number of recalls, number of patients biopsied and number of cancers identified within the Merrion Unit of the National Breastcheck Screening Program was obtained for comparison. RESULTS: One thousand six hundred eighty-eight referrals were triaged as "image first" over this period. 185 (11%) of patients required a biopsy of an identified lesion. Breast cancer was diagnosed in 65 patients (3.9%). During the same study period, of the 42,099 women who were screened for breast cancer, 496 (1.8%) underwent biopsy and 267 (0.63%) were diagnosed with breast cancer. CONCLUSION: Image first patients, who represent a cohort of "symptomatic" non-urgent women, have a greater rate of breast cancer detection than an asymptomatic screening population. This may have an impact on the appropriate triaging of symptomatic women in a national cancer center. PMID- 29582347 TI - In Vitro Assessment of Nasal Insufflation of Comminuted Drug Products Designed as Abuse Deterrent Using the Vertical Diffusion Cell. AB - In vitro evaluation of abuse deterrent formulations (ADFs) is a challenge since real abuse situations are variable and ADF technology is evolving. Specifically, an assessment of an ADF to deter nasal insufflation would be valuable. In this study, a vertical diffusion cell (VDC) was used to evaluate polyethylene oxide (PEO)-based tablets manipulated by three different forces. The commercially available products Oxycontin(r), an ADF, Opana(r), and metoprolol tartrate tablet formulations made in our laboratory were studied. Particle size distribution and percent recovery of manipulated tablets were measured. Grinding produced the lowest recovery and the smallest particle size distribution. Drug release was examined using a VDC by placing the dry comminuted particles on an enclosed wetted cellulose membrane. Dispensing dry particles on a VDC is atypical but includes some key features associated with an abuse situation where once the particles are snorted, the moisture in the nasal mucosa activates hydration and swelling of the polymers in the formulation, retarding drug release. Drug release from OxyContin(r), Opana(r), and metoprolol tablets were analyzed for the cutting, grinding, and milling modes of abuse. The analysis showed that in most cases, the mode of abuse produced different particle sizes with different release rates. Statistically different release rates were observed for metoprolol tablets made with different molecular weight PEO and with different porosities. These results indicate that within detection limits, the VDC can be used to quantitate release differences due to various modes of abuse used in this study. PMID- 29582348 TI - Comparison of detectability of breast cancer by abbreviated breast MRI based on diffusion-weighted images and postcontrast MRI. AB - PURPOSE: To compare the detectability of unenhanced abbreviated magnetic resonance imaging (MRI) based on diffusion-weighted imaging (DWI) and abbreviated postcontrast MRI for breast cancer. METHODS: The study population consisted of 87 patients undergoing breast MRI between December 2016 and March 2017 in a clinical setting. All breast MRIs were performed using a 1.5-T MRI scanner with a 16 channel breast radiofrequency coil. The abbreviated protocols based on DWI (AP1) and postcontrast MRI (AP2) were assessed independently by two radiologists. Sensitivity and specificity were calculated. Receiver operating characteristic analysis was performed and the areas under the curves (AUCs) were compared between AP1 and AP2. RESULTS: The study included 87 patients with 89 breast cancer lesions <= 2 cm in diameter. The sensitivity/specificity for AP1 and AP2 for reader 1 was 89.9/97.6% and 95.5/90.6%, respectively, and those for reader 2 was 95.5/94.1% and 98.9/94.1%, respectively. The AUCs for AP1 and AP2 for reader 1 were 0.9629 and 0.9640 (p = 0.95), respectively, and those for reader 2 were 0.9755 and 0.9843 (p = 0.46), respectively. CONCLUSIONS: The detectability of the unenhanced abbreviated protocol based on DWI would be comparable to that of abbreviated postcontrast MRI for breast cancer. PMID- 29582349 TI - Model reduction in mathematical pharmacology : Integration, reduction and linking of PBPK and systems biology models. AB - In this paper we present a framework for the reduction and linking of physiologically based pharmacokinetic (PBPK) models with models of systems biology to describe the effects of drug administration across multiple scales. To address the issue of model complexity, we propose the reduction of each type of model separately prior to being linked. We highlight the use of balanced truncation in reducing the linear components of PBPK models, whilst proper lumping is shown to be efficient in reducing typically nonlinear systems biology type models. The overall methodology is demonstrated via two example systems; a model of bacterial chemotactic signalling in Escherichia coli and a model of extracellular regulatory kinase activation mediated via the extracellular growth factor and nerve growth factor receptor pathways. Each system is tested under the simulated administration of three hypothetical compounds; a strong base, a weak base, and an acid, mirroring the parameterisation of pindolol, midazolam, and thiopental, respectively. Our method can produce up to an 80% decrease in simulation time, allowing substantial speed-up for computationally intensive applications including parameter fitting or agent based modelling. The approach provides a straightforward means to construct simplified Quantitative Systems Pharmacology models that still provide significant insight into the mechanisms of drug action. Such a framework can potentially bridge pre-clinical and clinical modelling - providing an intermediate level of model granularity between classical, empirical approaches and mechanistic systems describing the molecular scale. PMID- 29582350 TI - Root microbiota shift in rice correlates with resident time in the field and developmental stage. AB - Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field (e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment. PMID- 29582351 TI - Comparing human peritoneal fluid and phosphate-buffered saline for drug delivery: do we need bio-relevant media? AB - An understanding of biological fluids at the site of administration is important to predict the fate of drug delivery systems in vivo. Little is known about peritoneal fluid; therefore, we have investigated this biological fluid and compared it to phosphate-buffered saline, a synthetic media commonly used for in vitro evaluation of intraperitoneal drug delivery systems. Human peritoneal fluid samples were analysed for electrolyte, protein and lipid levels. In addition, physicochemical properties were measured alongside rheological parameters. Significant inter-patient variations were observed with regard to pH (p < 0.001), buffer capacity (p < 0.05), osmolality (p < 0.001) and surface tension (p < 0.05). All the investigated physicochemical properties of peritoneal fluid differed from phosphate-buffered saline (p < 0.001). Rheological examination of peritoneal fluid demonstrated non-Newtonian shear thinning behaviour and predominantly exhibited the characteristics of an entangled network. Inter patient and inter-day variability in the viscosity of peritoneal fluid was observed. The solubility of the local anaesthetic lidocaine in peritoneal fluid was significantly higher (p < 0.05) when compared to phosphate-buffered saline. Interestingly, the dissolution rate of lidocaine was not significantly different between the synthetic and biological media. Importantly, and with relevance to intraperitoneal drug delivery systems, the sustained release of lidocaine from a thermosensitive gel formulation occurred at a significantly faster rate into peritoneal fluid. Collectively, these data demonstrate the variation between commonly used synthetic media and human peritoneal fluid. The differences in drug release rates observed illustrate the need for bio-relevant media, which ultimately would improve in vitro-in vivo correlation. PMID- 29582352 TI - Correlation analysis of monocyte subsets and insulin resistance considering fetuin-A involvement in patients with type 2 diabetes. AB - BACKGROUND: Fetuin-A is a multifunctional circulating glycoprotein that can induce insulin resistance. Lately, adipose tissue has gained prominence as an effector site of fetuin-A. Although fetuin-A-induced proinflammatory polarization and migration of macrophages plays a crucial role, it remains obscure whether monocyte subsets in circulation could simulate characteristics of macrophages in adipose tissues. This study aims to investigate the correlation between monocyte subsets with fetuin-A and its relevant insulin resistance. RESULTS: We evaluated serum fetuin-A levels in 107 patients with type 2 diabetes (T2D). Using flow cytometry, we classified monocyte subsets into three subtypes: (a) classical, CD14++CD16-; (b) intermediate, CD14++CD16+, the most proinflammatory one; (c) and nonclassical, CD14+CD16++. We assessed the insulin resistance by the homeostasis model assessment for insulin resistance (HOMA-IR) in 68 patients without insulin injections. We observed no correlation between fetuin-A levels and classical (rho = - 0.005; P = 0.959), intermediate (rho = 0.022; P = 0.826), and nonclassical monocyte counts (rho = 0.063; P = 0.516), respectively. In addition, no significant correlation was found between log (HOMA-IR) and classical (rho = 0.052; P = 0.688), intermediate (rho = 0.054; P = 0.676), and nonclassical monocyte counts (rho = 0.012; P = 0.353), respectively. However, serum fetuin-A levels showed positive correlation with log (HOMA-IR) (rho = 0.340; P = 0.007). Multiple regression analyses revealed a significant relationship between fetuin-A and log (HOMA-IR) (beta = 0.313; P = 0.016), but not with monocyte subsets. CONCLUSIONS: Monocyte subsets in circulation, including proinflammatory intermediate monocytes, were not associated with fetuin-A and insulin resistance.

PMID- 29582353 TI - Development of apical hypertrophic cardiomyopathy with age in a transgenic mouse model carrying the cardiac actin E99K mutation. AB - In both humans and mice, the Glu-99-Lys (E99K) mutation in the cardiac actin gene (ACTC) results in little understood apical hypertrophic cardiomyopathy (AHCM). To determine how cross-bridge kinetics change with AHCM development, we applied sinusoidal length perturbations to skinned papillary muscle fibres from 2- and 5 month old E99K transgenic (Tg) and non-transgenic (NTg) mice, and studied tension and its transients. These age groups were chosen because our preliminary studies indicated that AHCM develops with age. Fibres from 5-month old E99K mice showed significant decreases in tension, stiffness, the rate of the medium-speed exponential process and its magnitude compared to non-transgenic control. The nucleotide association constants increased with age, and they were significantly larger in E99K compared to NTg. However, there were no large differences in the rates of the cross-bridge detachment step, the rates of the force generation step, or the phosphate association constant. Our result on force/cross-bridge demonstrates that the decreased active tension of E99K fibres was caused by a decreased amount of force generated per each cross-bridge. The effects were generally less or insignificant at 2 months. A pCa-tension study showed increased Ca2+-sensitivity (pCa50) with age in both the E99K and NTg sample groups, and pCa50 was significantly larger (but only for 0.05-0.06 pCa units) in E99K than in NTg groups. A significant decrease in cooperativity (nH) was observed only in 5 month old E99K mice. We conclude that the AHCM-causing ACTC E99K mutation is associated with progressive alterations in biomechanical parameters, with changes smaller at 2 months but larger at 5 months, correlating with the development of AHCM.

PMID- 29582356 TI - No reliable gene expression biomarkers of current or impending neurocognitive impairment in peripheral blood monocytes of persons living with HIV. AB - Events leading to and propagating neurocognitive impairment (NCI) in HIV-1 infected (HIV+) persons are largely mediated by peripheral blood monocytes. We previously identified expression levels of individual genes and gene networks in peripheral blood monocytes that correlated with neurocognitive functioning in HIV+ adults. Here, we expand upon those findings by examining if gene expression data at baseline is predictive of change in neurocognitive functioning 2 years later. We also attempt to validate the original findings in a new sample of HIV+ patients and determine if the findings are HIV specific by including HIV uninfected (HIV-) participants as a comparison group. At two time points, messenger RNA (mRNA) was isolated from the monocytes of 123 HIV+ and 60 HIV- adults enrolled in the Multicenter AIDS Cohort Study and analyzed with the Illumina HT-12 v4 Expression BeadChip. All participants received baseline and follow-up neurocognitive testing 2 years after mRNA analysis. Data were analyzed using standard gene expression analysis and weighted gene co-expression network analysis with correction for multiple testing. Gene sets were analyzed for GO term enrichment. Only weak reproducibility of associations of single genes with neurocognitive functioning was observed, indicating that such measures are unreliable as biomarkers for HIV-related NCI; however, gene networks were generally preserved between time points and largely reproducible, suggesting that these may be more reliable. Several gene networks associated with variables related to HIV infection were found (e.g., MHC I antigen processing, TNF signaling, interferon gamma signaling, and antiviral defense); however, no significant associations were found for neurocognitive function. Furthermore, neither individual gene probes nor gene networks predicted later neurocognitive change. This study did not validate our previous findings and does not support the use of monocyte gene expression profiles as a biomarker for current or future HIV-associated neurocognitive impairment. PMID- 29582357 TI - Does time taken to achieve jaundice-clearance influence survival of the native liver in post-Kasai biliary atresia? AB - BACKGROUND: We reviewed the time taken for post-portoenterostomy (PE) biliary atresia (BA) patients to obtain jaundice-clearance (total bilirubin <= 1.2 mg/dL; JC) post-PE to determine if JC time (JCT) is prognostic for survival of the native liver (SNL). METHODS: The subjects were 66 BA patients treated with PE at our institute between 1989, the year when liver transplantation (LTx) became available in Japan, and 2014. JCT was used to create three groups (<= 30 days: n = 14; 31-60 days: n = 31; >= 61 days: n = 21). Medical records were reviewed retrospectively to evaluate: age at onset of symptoms, duration of symptoms pre PE, age and weight at PE, serum liver function tests, incidence of cholangitis, and micro-bile duct size at PE. RESULTS: Age at onset of symptoms, age and weight at PE, duration of symptoms pre-PE, and micro-bile duct size were similar for all patients in all three groups. JCT and SNL appeared to correlate because preoperative total bilirubin (7.1, 9.6, 10.2 mg/dL; P < 0.05) was significantly lower in the JCT <= 30 days group (P < 0.05) while there was a significant decrease in SNL (P < 0.03) and a significant increase in LTx (P < 0.01) in the JCT >= 61 days group. All LTx subjects who achieved JC were found to have developed cholangitis within 3 months of PE. CONCLUSION: During the follow-up of post-PE subjects, longer JCT and cholangitis occurrence within 3 months of PE would appear to be negative prognostic factors for SNL while preoperative total bilirubin would appear to be a positive prognostic factor for SNL. PMID- 29582358 TI - Follow-up after surgery for gastric cancer: how to do it. AB - There is no consensus on follow-up after gastric surgery for cancer, nor evidence that it improves outcomes. We investigated the impact of intensity of follow-up, comparing the regimens adopted by two centres, in Italy and in the UK. Patients who underwent surgery for gastric and junctional type-3 adenocarcinoma, between September 2009 and April 2013, at the Surgical Clinic, University of Brescia (Italy), and at the Department of Upper Gastrointestinal Surgery, University College London Hospital (UK), were identified. Patients' demographics, stage, recurrence rates, modality of detection and treatment were recorded. Overall survival and costs were compared between the two protocols. A total of 128 patients were included. Recurrence rates were similar (p = 0.349), with more than 70% diagnosed during regular follow-up appointments in both centres. At univariate and multivariate analysis, stage I and treatment of recurrence were associated with a better survival. Patients treated for recurrence at the Italian centre showed an almost significant better survival (p = 0.052). The intensive Italian surveillance protocol was associated with significant higher costs per year. Follow-up and early detection of recurrence did not affect survival in the analysed series, focused on periods in which chemotherapy was ineffective towards recurrence. However, intensive follow-up allowed a greater number of patients to receive a treatment for recurrence; this might prove useful in the next few years, when more effective chemotherapy combinations are expected to become available. The costs could be reduced by adopting a less intensive surveillance programme. PMID- 29582359 TI - Robotic versus standard open pancreatectomy: a propensity score-matched analysis comparison. AB - Interest in robotic pancreatectomy has been greatly increasing over the last decade. However, evidence supporting the benefits of robotic over open pancreatectomy is still outstanding. This study aims to assess the safety and efficacy of robotic pancreatectomy compared with the conventional open surgical approach. Propensity score-matched (1:1) was used to balance age, sex, BMI, ASA, tumor size, and malignancy of 17 robotic pancreaticoduodenectomies (PD), 12 pancreatic enucleations (PE), and 28 distal pancreatectomies (DP); and was compared with the open standard approach. Robotic PD was associated with longer operative time (594 vs. 413 min; p = 0.03) and decreased blood loss (190 vs. 394 ml; p = 0.001). Robotic PE showed a lower mean length of hospital stay (8.4 vs. 12.8 days; p = 0.04) and, in addition, robotic DP showed less blood loss (175 vs. 375 ml; p = 0.01), less severe morbidities (7.14 vs. 17.9%; p = 0.02), and a reduced mean length of hospital stay (8.9 vs. 15.1; p = 0.001). Overall, conversion rate was 4 (7%). Robotic pancreatectomy is as safe and effective as the standard open surgical approach with reduced blood loss in PD and DP, length of hospital stay in PE and DP, and severe morbidity in DP. PMID- 29582360 TI - Comparison of oropharyngeal leak pressure between the Ambu(r) AuraGainTM and the LMA(r) SupremeTM supraglottic airways: a randomized-controlled trial. AB - PURPOSE: Studies comparing the recently introduced Ambu(r) AuraGainTM (Auragain) with the LMA(r) SupremeTM (Supreme) supraglottic airway (SGA) have reported conflicting results regarding differences in oropharyngeal leak pressure (OLP). This randomized-controlled trial investigated the OLP of the Auragain compared with the Supreme in patients undergoing ambulatory surgery. METHODS: Adult patients with a body mass index <= 40 kg.m-2 presenting for ambulatory surgery and requiring an SGA were randomized to receive either the Auragain or the Supreme. Anesthesia was induced with lidocaine (1 mg.kg-1), fentanyl (1-2 MUg.kg 1), and propofol (2-3 mg.kg-1). The SGA was inserted using a standard technique with the cuff inflated to 60 cmH2O. The groups were compared for the primary outcome of OLP. RESULTS: One hundred sixty-five patients (n = 81, Auragain; n = 84, Supreme) completed the study. Demographics were similar between the groups. The mean (standard deviation [SD]) OLP was significantly higher in the Auragain than in the Supreme group [26.4 (2.8) cmH2O vs 21.6 (3.4) cmH2O, respectively; difference in means (MD), 4.8 cmH2O; 95% confidence interval (CI), 3.9 to 5.8; P < 0.001]. The mean (SD) insertion time was longer in the Auragain than in the Supreme group [13 (4) sec vs 11 (3) sec, respectively; MD, 2 sec; 95% CI, 1 to 3 sec; P < 0.001]. CONCLUSION: In patients undergoing ambulatory anesthesia, the OLP was higher but took longer to insert with the Auragain than with the Supreme. A higher OLP may allow for SGAs to be utilized in a wider range of patients and procedures. TRIAL REGISTRATION: www.clinicaltrials.gov (NCT02816463). Registered 28 June 2016.

We examined primary care providers' perspective on use of decision aids and explored whether providers' beliefs and interest in use of a decision aid was associated with offering the prostate-specific antigen (PSA) test for early detection of prostate cancer. Data were obtained from 2016 DocStyles, an annual, web-based survey of U.S. healthcare professionals including primary care physicians (n = 1003) and nurse practitioners (n = 253). We found that the majority of primary care providers reported not using (patient) decision aids for prostate cancer screening, but were interested in learning about and incorporating these tools in their practice. Given the potential of decision aids to guide in informed decision-making, there is an opportunity for evaluating existing decision aids for prostate cancer screening for clinical use. PMID- 29582363 TI - Electrophysiological characteristics and radiofrequency ablation of sustained monomorphic ventricular tachycardia in adult patients with isolated ventricular noncompaction. AB - PURPOSE: This study examined electrophysiological characteristics and outcomes of patients with sustained ventricular tachycardia (VT) in the setting of isolated ventricular noncompaction (IVNC). BACKGROUND: In patients with IVNC, VT has been associated with sudden cardiac death. However, the electrophysiological characteristics and optimal management of these VTs are only incompletely understood. METHODS: This retrospective cohort study assessed arrhythmia characteristics and outcomes in IVNC patients with sustained monomorphic VTs. Data were obtained from five academic centers covering the time period from January 1, 2006, to December 31, 2016, with a median follow-up of 40 months. RESULTS: Eighteen consecutive IVNC patients with sustained VTs (12 males [66%], mean age of 44.4 +/- 16.9 years) were enrolled. Seven (39%) patients underwent VT ablation (five males, mean age of 43.3 +/- 15.5 years) and nine (50%) patients received ICD therapy. Six of 18 patients (33%) died during a median follow-up of 40 months. Of these, three had ICDs, two had undergone VT ablation, and one had received only antiarrhythmic drugs. Among the seven patients with prior VT ablation, five VTs in the RV (three RVOT and one tricuspid annulus) and two LV VTs (one anterolateral papillary muscle and one inferolateral wall) were localized by 3-D mapping and successfully ablated. In six of seven ablation cases (85.7%), the VTs were distant from the noncompaction zone. VTs appeared to be focal in 57% (4/7) and macro-reentry in 43% (3/7) of patients based on 3-D mapping and entrainment studies. The success rate of VT ablation was 85.7% with one VT recurrence and two deaths during the mean follow-up of 54 (28-115) months. CONCLUSIONS: IVNC Patients with sustained VTs appear to have a poor prognosis despite receiving ICD or apparently successful VT ablation therapy. Further, most VTs appear to arise remote from the noncompaction zone. Whether these VTs were "idiopathic" or related to IVNC was uncertain. PMID- 29582365 TI - Evaluation of Cardiovascular Toxicity Associated with Treatments Containing Proteasome Inhibitors in Multiple Myeloma Therapy. AB - INTRODUCTION: Recently new treatment options have substantially increased survival for patients with relapsed and/or refractory multiple myeloma (RRMM). Among these, proteasome inhibitors (PI), such as bortezomib and carfilzomib, offer high response rate and prolonged survival. These agents are generally well tolerated but demonstrated a significant cardiovascular toxicity, mostly for regimen containing carfilzomib. AIM: To assess the cardiovascular damage in patients treated with PI for RRMM. METHODS: 28 consecutive subjects treated with PI for RRMM were evaluated and compared with a population of 22 control (Con) subjects, matched for age, sex and mean 24 h blood pressure (24hMBP). All individuals underwent trans-thoracic echocardiography, ambulatory blood pressure monitoring and pulse wave velocity (PVW) study. RESULTS: PI patients did not have significant differences in blood pressure load and PWV compared to controls. Among echocardiographic parameters, the global longitudinal strain (GLS) was significantly decreased in PI subjects (p = 0.02). The GLS was significantly lower also considering only patients treated with carfilzomib. Moreover, among carfilzomib patients, we found increase values of left ventricle mass indexed by BSA (LVMi; p = 0.047). After correction for age, sex, BSA, 24hMBP and morphological and functional parameters of LV, treatment with PI and carfilzomib were significantly associated with GLS (p = 0.01; p = 0.036, respectively). CONCLUSIONS: PI treatment is associated with subclinical LV dysfunction in patients with RRMM compared to controls, as demonstrated by lower GLS values. These results are confirmed also considering patients treated with carfilzomib. Moreover, in this subgroup of patients, the LVMi is also increased, suggesting higher cardiotoxicity with this treatment. PMID- 29582367 TI - ? PMID- 29582366 TI - The reversal effect of Ginsenoside Rh2 on drug resistance in human colorectal carcinoma cells and its mechanism. AB - Recent studies hint that Ginsenoside is involved in cancer prevention and treatment. In this study, we investigated the effect of Ginsenoside Rh2 on drug resistance in human colorectal carcinoma (CRC) cells and its mechanism. The resistance reversion effect of Ginsenoside Rh2 in CRC cells was analyzed using CCK-8 assay. After treating with Ginsenoside Rh2, the cell cycle distribution and cellular apoptosis were analyzed by flow cytometry, cell migration was determined by transwell migration assay, the expression of drug-resistance genes and proteins were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Ginsenoside Rh2 could enhance the cytotoxicity of 5-FU in drug-resistant CRC cells (LoVo/5-FU and HCT-8/5-FU). Treatment with Ginsenoside Rh2 could result in an increase of cell numbers in G0/G1 phase accompanied with a decrease in S-phase, and induced cellular apoptosis in drug-resistant CRC cells. In addition, the migration process and EMT process of drug-resistant CRC cells were suppressed by treatment of Ginsenoside Rh2. Compared to control group, expression of drug-resistance genes, such as MRP1, MDR1, LRP and GST, were negatively correlated to Ginsenoside Rh2. All these results indicated that Ginsenoside Rh2 could effectively reverse drug resistance in human colorectal carcinoma cell and its mechanism involved the prevention of cellular proliferation and migration, the promotion of cellular apoptosis and the alteration of drug-resistance genes, which suggested that Ginsenoside Rh2 may act as a promising candidate for drug resistance in human colorectal carcinoma chemotherapy. PMID- 29582369 TI - Field Cancerization Therapies for Management of Actinic Keratosis: A Narrative Review. AB - Actinic keratoses (AKs) are atypical, precancerous proliferations of keratinocytes that develop because of chronic exposure to ultraviolet (UV) radiation. Treatment of AK can be lesion-directed or field-directed. Field cancerization theory postulates that the skin surrounding AK is also at increased risk for possible malignant transformation since it has been exposed to the same chronic UV light. Field-directed therapies thus have the potential to address subclinical damage, reduce AK recurrence rates, and potentially reduce the risk of squamous cell carcinoma (SCC) development. Published clinical studies have found lesion clearance rates ranging from 81 to 91% for photodynamic therapy (PDT) with either aminolevulinic acid (ALA) or methylaminolevulinate (MAL). Clinical studies have also been published on various topical treatments. Complete clinical clearance (CCC) was significantly higher in patients treated with a combination of 5-fluorouracil and salicylic acid (5-FU-SA) than in the vehicle group across multiple studies, and CCC ranged between 46 and 48% following treatment with imiquimod. Additionally, treatment with diclofenac sodium (DFS) found reduction in lesion sizes to range from 67 to 75%. Reported results have been similar for another non-steroidal anti-inflammatory drug (NSAID), piroxicam, which has more cyclooxygenase (COX)-1 activity than DFS. Active treatments with ingenol mebutate were also significantly more effective than vehicle at clearing AK lesions. All treatments resulted in mild, localized skin reactions. PDT using conventional light sources was associated with increased severity of pain and/or discomfort, while PDT using daylight as the light source was associated with less pain and occasionally no pain at all. Though no widely accepted algorithm for the treatment of AKs exists, field-directed therapy can be particularly useful for treating photo-exposed areas containing multiple AKs. Additional research with more direct comparisons between these field-directed therapies will help clinicians determine the best therapeutic approach. Here, we provide a balanced and comprehensive narrative review of the literature, considering both light based and topical therapies with a focus on their field-therapy aspects, and propose a therapeutic algorithm for selecting an appropriate treatment in the clinical setting. PMID- 29582368 TI - Expression of kallikrein-related peptidase 13 is associated with poor prognosis in esophageal squamous cell carcinoma. AB - OBJECTIVE: Our previous differential transcriptome analysis between a paired specimen of normal and esophageal squamous cell carcinoma (ESCC) tissues found aberrant expression of kallikrein-related peptidase 13 (KLK13) in tumors. In this study, we evaluated the expression of KLK13 in many ESCC cases in relation with clinical features, and the prognosis. METHODS: Eighty-eight ESCC cases were subjected to immunohistological staining for KLK13 and classified into KLK13 negative and KLK13-positive groups. Difference of clinical features and the prognosis between the groups was analyzed. RESULTS: In normal esophageal mucosa, KLK13 expression was evident but limited in the stratum granulosum in all cases. By contrast, only 27 of 88 ESCC samples showed KLK13 expression, whereas the remaining 61 tumors showed no KLK13 expression. The KLK13-positive group was significantly associated with pT classification (deeper tumor invasions; P = 0.0282), pN classification (lymph node metastasis; P = 0.0163), and advanced TNM stage (P = 0.0198). In KLK13-positive samples, KLK13-expressing cells often expressed Ki67, a proliferation marker, unlike normal mucosa, in which Ki67 expressing cells were limited to the basal layer and did not express KLK13. Compared with patients with KLK13-negative group, KLK13-positive group showed poorer postoperative prognosis. CONCLUSION: Relatively high levels of KLK13 expression in ESCC were associated with cell proliferation and correlated with tumor progression, advanced cancer stage, and poor prognosis. PMID- 29582370 TI - Immunofluorescence Staining Protocols for Major Autophagy Proteins Including LC3, P62, and ULK1 in Mammalian Cells in Response to Normoxia and Hypoxia. AB - Immunofluorescence is an invaluable technique widely used in cell biology. This technique allows visualization of the subcellular distribution of different target proteins or organelles, by specific recognition of the antibody to the endogenous protein itself or to its antigen via the epitope. This technique can be used on tissue sections, cultured cells, or individual cells. Meanwhile, immunofluorescence can also be used in combination with non-antibody fluorescent staining, such as DAPI or fluorescent fusion proteins, e.g., GFP or YFP, etc.Autophagy is a catabolic pathway in which dysfunctional organelles and cellular components are degraded via lysosomes. During this process, cytoplasmic LC3 translocates to autophagosomal membranes. Therefore, cells undergoing autophagy can be identified by visualizing fluorescently labeled LC3 or other autophagy markers. Immunofluorescence is an important part of autophagy detection methods even if observation of the formation of autophagosome by transmission electron microscopy has become a gold standard for characterizing autophagy.By observing the immunofluorescence staining of some key autophagy proteins, we can intuitively evaluate the levels of autophagy in samples. Herein, this protocol describes the predominant method used for the research of autophagy, which mainly focuses on the immunofluorescence staining of cellular LC3, P62, and ULK1 in response to normoxia and hypoxia, by presenting the detailed materials required and methodology. PMID- 29582371 TI - Determining Inorganic and Organic Nitrogen. AB - Nitrogen (N) is one of the key nutrients for algal growth and is an integral part of many cellular components, for example in proteins. Being able to determine the inorganic and organic pools of N is consequently critical for algal cultivation. In this chapter we present the methods we use for determining dissolved inorganic nitrogen (DIN), dissolved organic nitrogen (DON), and particulate organic nitrogen (PON). The methods presented here for DIN rely on colorimetric methods and those of DON and PON on filtration and high temperature catalytic oxidation. PMID- 29582372 TI - Determining Dissolved and Biogenic Silica. AB - Most algae do not use silicon in any form with one notable exception, diatoms. Silicon is a major constituent of diatoms. Diatoms are characterized by high growth rates and are often one of the key groups in forming algal blooms in natural waters, and as such it is an interesting group for cultivation. In this chapter we present methods for determining dissolved silica (DSi) and biogenic silica (BSi), oxide forms of silicon, based on colorimetric methods. BSi is determined after filtration and alkaline digestion. PMID- 29582373 TI - Isolation and Enrichment of Newborn and Adult Skin Stem Cells of the Interfollicular Epidermis. AB - The interfollicular epidermis regenerates from a heterogeneous population of basal cells undergoing either self-renewal or terminal differentiation, thereby balancing cell loss in tissue turnover or in wound repair. In this chapter, we describe a reliable and simple method for isolating interfollicular epithelial stem cells from the skin of newborn mice or from tail and ear skin of adult mice using fluorescence-activated cell sorting (FACS). We also provide a detailed protocol for culturing interfollicular epidermal stem cells and to assess their proliferative potential and self-renewing ability. These techniques are useful for directly evaluating epidermal stem cell function in normal mice under different conditions or in genetically modified mouse models. PMID- 29582374 TI - Isolation and Cultivation of Epidermal (Stem) Cells. AB - Recent studies have shown that epidermal stem cells derived from the epidermis of are able to form hair follicles in the presence of hair follicle-inducing cells.

AB - Epithelia are under constant threat from environmental carcinogens and none more so than squamous epithelia, which form the outermost linings of our bodies. Hence malignancies of squamous epithelia are collectively the most common cancer type and with the highest mortality, despite a constant cell turnover and only relatively rare long-lived adult tissue stem cells. Genetic analysis from SCC whole genome sequencing reveals commonality in mutated genes, despite various etiological factors. Most SCC types have been shown to exhibit hierarchical growth, in which a high frequency of cancer stem cells is associated with poor prognosis. For human cutaneous SCC (cSCC), we have shown that cancer stem cells express CD133 and that this population can recreate tumor heterogeneity in a novel in vivo model. CD133+ cSCC cells is small subset of tumor cells (~1%) in the outer layer of cSCC that are highly enriched for tumor-initiating capacity (TIC) (~1/400) compared to unsorted cSCC cells (~1/106). Xenografts of CD133+ cSCC recreated the original cSCC tumor histology and organizational hierarchy, while CD133- cells did not. Only CD133+ cells demonstrated the capacity for self renewal in serial transplantation studies. Hence, cSCC has the potential to be the ideal model in which to study SCC biology. PMID- 29582376 TI - Isolation, Culture, and Motility Measurements of Epidermal Melanocytes from GFP Expressing Reporter Mice. AB - In this article, we provide a method to isolate primary epidermal melanocytes from reporter mice, which also allow targeted gene inactivation. The mice from which these cells are isolated are bred into a Rosa26 mT/mG reporter background, which results in GFP expression in the targeted melanocytic cell population. These cells are isolated and cultured to >95% purity. The cells can be used for gene expression studies, clonogenic experiments, and biological assays, such as capacity for migration. Melanocytes are slow moving cells, and we also provide a method to measure motility using individual cell tracking and data analysis. PMID- 29582377 TI - Serial dependence in position occurs at the time of perception. AB - Observers perceive objects in the world as stable over space and time, even though the visual experience of those objects is often discontinuous and distorted due to masking, occlusion, camouflage, or noise. How are we able to easily and quickly achieve stable perception in spite of this constantly changing visual input? It was previously shown that observers experience serial dependence in the perception of features and objects, an effect that extends up to 15 seconds back in time. Here, we asked whether the visual system utilizes an object's prior physical location to inform future position assignments in order to maximize location stability of an object over time. To test this, we presented subjects with small targets at random angular locations relative to central fixation in the peripheral visual field. Subjects reported the perceived location of the target on each trial by adjusting a cursor's position to match its location. Subjects made consistent errors when reporting the perceived position of the target on the current trial, mislocalizing it toward the position of the target in the preceding two trials (Experiment 1). This pull in position perception occurred even when a response was not required on the previous trial (Experiment 2). In addition, we show that serial dependence in perceived position occurs immediately after stimulus presentation, and it is a fast stabilization mechanism that does not require a delay (Experiment 3). This indicates that serial dependence occurs for position representations and facilitates the stable perception of objects in space. Taken together with previous work, our results show that serial dependence occurs at many stages of visual processing, from initial position assignment to object categorization.

PMID- 29582381 TI - The Effect of Chronic Exercise Training on Leptin: A Systematic Review and Meta Analysis of Randomized Controlled Trials. AB - BACKGROUND: Leptin is a hormone associated with satiety, lipid oxidation, energy expenditure, and energy homeostasis. To date, the current body of research examining the effect of chronic exercise training on leptin has yielded inconsistent results. OBJECTIVE: The purpose of this meta-analysis was to provide a quantitative estimate of the magnitude of change in leptin levels following participation in exercise interventions lasting >= 2 weeks. METHODS: All studies included were peer-reviewed and published in English. To be included, studies randomized human participants to an exercise training group or non-exercise comparison group for an exercise training intervention. Leptin levels were measured at baseline, during, and/or after completion of the exercise training program. Random-effects models were used to aggregate a mean effect size (ES) and 95% confidence intervals (CIs), and identify potential moderators. RESULTS: Seventy-two randomized controlled trials met the inclusion criteria and resulted in 107 effects (n = 3826). The mean ES of 0.24 (95% CI 0.16-0.32, p < 0.0001) indicated a decrease in leptin following an exercise training program. A decrease in %Fat (beta = - 0.07, p < 0.01) was associated with a decrease in leptin after accounting for the type of control group (beta = - 0.38, p < 0.0001) used in each study. CONCLUSION: These results suggest that engaging in chronic exercise training (>= 2 weeks) is associated with a decrease in leptin levels for individuals regardless of age and sex. However, a greater decrease in leptin occurred with a decreased percentage of body fat.

AB - BACKGROUND: Immigrants comprise approximately 13% of the US population and 33% lack health coverage. Asian Americans are the fastest growing immigrant group; many lack a usual source of care. This study examines factors associated with health insurance among Asian American immigrants living in New York City. METHODS: Community needs assessments were conducted among Asian American subgroups in New York City from 2013 to 2015; analysis was completed in 2017 and 2018. Descriptive statistics examined factors associated with health insurance status while stratifying by Asian ethnic subgroup; multivariable logistic regression models further assessed these associations (p < 0.05 significance level). RESULTS: Approximately 19% of the study population (n = 1399) was uninsured. Logistic regression models adjusted for all factors. Among East Asians, insurance status was associated with female sex (OR = 2.8, p = 0.005), excellent/very good health status (OR = 3.5, p = 0.014), and seeing a private doctor when sick or injured (OR = 3.2, p = 0.033). Among South Asians, insurance status was associated with high school/some college and college education (OR = 2.6 and 2.9, respectively, p = 0.039 and p = 0.021), having a routine health check in the past year (OR = 6.4, p < 0.001), no diabetes diagnosis (OR = 2.7, p = 0.030), and a tuberculosis diagnosis (OR = 4.7, p = 0.019). Among Southeast Asians, insurance status was associated with less than high school education (p < 0.05), living in the USA > 20 years (OR = 3.7, p = 0.009), having a routine health check in the past year (OR = 5.6, p = 0.025), and seeing a private doctor when sick or injured (OR = 2.6, p = 0.018). CONCLUSIONS: Health insurance status was associated with differing factors among each subgroup. Findings may inform strategies to address challenges and barriers of healthcare access to immigrants, making healthcare more accessible to this underserved population. PMID- 29582385 TI - 1H, 13C and 15N backbone resonance assignment of the lamin C-terminal region specific to prelamin A. AB - Lamins are the main components of the nucleoskeleton. They form a protein meshwork that underlies the inner nuclear membrane. Mutations in the LMNA gene coding for A-type lamins (lamins A and C) cause a large panel of human diseases, referred to as laminopathies. These diseases include muscular dystrophies, lipodystrophies and premature aging diseases. Lamin A exhibits a C-terminal region that is different from lamin C and is post-translationally modified. It is produced as prelamin A and it is then farnesylated, cleaved, carboxymethylated and cleaved again in order to become mature lamin A. In patients with the severe Hutchinson-Gilford progeria syndrome, a specific single point mutation in LMNA leads to an aberrant splicing of the LMNA gene preventing the post-translational processing of prelamin A. This leads to the accumulation of a permanently farnesylated lamin A mutant lacking 50 amino acids named progerin. We here report the NMR 1H, 15N, 13CO, 13Calpha and 13Cbeta chemical shift assignment of the C terminal region that is specific to prelamin A, from amino acid 567 to amino acid 664. We also report the NMR 1H, 15N, 13CO, 13Calpha and 13Cbeta chemical shift assignment of the C-terminal region of the progerin variant, from amino acid 567 to amino acid 614. Analysis of these chemical shift data confirms that both prelamin A and progerin C-terminal domains are largely disordered and identifies a common partially populated alpha-helix from amino acid 576 to amino acid 585. This helix is well conserved from fishes to mammals.

AB - Fibroblast growth factors receptors (FGFR) are transmembrane protein tyrosine kinases involved in many cellular process, including growth, differentiation and angiogenesis. Dysregulation of FGFR enzymatic activity is associated with developmental disorders and cancers; therefore FGFRs have become attractive targets for drug discovery, with a number of agents in late-stage clinical trials. Here, we present the backbone resonance assignments of FGFR3 tyrosine kinase domain in the ligand-free form and in complex with the canonical FGFR kinase inhibitor PD173074. Analysis of chemical shift changes upon inhibitor binding highlights a characteristic pattern of allosteric network perturbations that is of relevance for future drug discovery activities aimed at development of conformationally-selective FGFR inhibitors. PMID- 29582386 TI - Solution NMR assignment of the C-terminal domain of human chTOG. AB - The microtubule regulatory protein colonic and hepatic tumor overexpressed gene (chTOG), also known as cytoskeleleton associated protein 5 (CKAP5) plays an important role in organizing the cytoskeleton and in particular in the assembly of k-fibres in mitosis. Recently, we dissected the hitherto poorly understood C terminus of this protein by discovering two new domains-a cryptic TOG domain (TOG6) and a smaller, helical domain at the very C-terminus. It was shown that the C-terminal domain is important for the interaction with the TACC domain in TACC3 during the assembly of k-fibres in a ternary complex that also includes clathrin. Here we now present the solution NMR assignment of the chTOG C-terminal domain which confirms our earlier prediction that it is mainly made of alpha helices. However, the appearance of the 1H-15N HSQC spectrum is indicative of the presence of a considerable amount of unstructured and possibly flexible portions of protein in the domain. PMID- 29582388 TI - Action influences unconscious visual processing. AB - It has long been known that action is tightly linked to visual perception. In support of this connection, recent studies have shown that making a simple action towards a visual object can bias subsequent visual processing of features of the acted-on object. The present study examined whether conscious awareness of the acted-on object is necessary to yield this action effect. In two experiments, we found that making an action towards an invisible object resulted in greater priming in a subsequent visual search task. This shows that conscious awareness is not necessary to obtain the action-induced visual bias. More importantly, the result implies that action might amplify the sensory signal from the subliminally presented object, which is presumed to occur during early visual processing. PMID- 29582387 TI - Psychophysics with children: Investigating the effects of attentional lapses on threshold estimates. AB - When assessing the perceptual abilities of children, researchers tend to use psychophysical techniques designed for use with adults. However, children's poorer attentiveness might bias the threshold estimates obtained by these methods. Here, we obtained speed discrimination threshold estimates in 6- to 7 year-old children in UK Key Stage 1 (KS1), 7- to 9-year-old children in Key Stage 2 (KS2), and adults using three psychophysical procedures: QUEST, a 1-up 2-down Levitt staircase, and Method of Constant Stimuli (MCS). We estimated inattentiveness using responses to "easy" catch trials. As expected, children had higher threshold estimates and made more errors on catch trials than adults. Lower threshold estimates were obtained from psychometric functions fit to the data in the QUEST condition than the MCS and Levitt staircases, and the threshold estimates obtained when fitting a psychometric function to the QUEST data were also lower than when using the QUEST mode. This suggests that threshold estimates cannot be compared directly across methods. Differences between the procedures did not vary significantly with age group. Simulations indicated that inattentiveness biased threshold estimates particularly when threshold estimates were computed as the QUEST mode or the average of staircase reversals. In contrast, thresholds estimated by post-hoc psychometric function fitting were less biased by attentional lapses. Our results suggest that some psychophysical methods are more robust to attentiveness, which has important implications for assessing the perception of children and clinical groups. PMID- 29582389 TI - Memory guidance in distractor suppression is governed by the availability of cognitive control. AB - Information stored in the memory systems can affect visual search. Previous studies have shown that holding the to-be-ignored features of distractors in working memory (WM) could accelerate target selection. However, such facilitation effect was only observed when the cued to-be-ignored features remained unchanged within an experimental block (i.e., the fixed cue condition). No search benefit was obtained if the to-be-ignored features varied from trial to trial (i.e., the varied cue condition). In the present study, we conducted three behavioral experiments to investigate whether the WM and long-term memory (LTM) representations of the to-be-ignored features could facilitate visual search in the fixed cue (Experiment 1) and varied cue (Experiments 2 and 3) conditions. Given the importance of the processing time of cognitive control in distractor suppression, we divided visual search trials into five quintiles based on their reaction times (RTs) and examined the temporal characteristics of the suppression effect. Results showed that both the WM and LTM representations of the to-be ignored features could facilitate distractor suppression in the fixed cue condition, and the facilitation effects were evident across the quintiles in the RT distribution. However, in the varied cue condition, the RT benefits of the WM matched distractors occurred only in the trials with the longest RTs, whereas no advantage of the LTM-matched distractors was observed. These results suggest that the effective WM-guided distractor suppression depends on the availability of cognitive control and the LTM-guided suppression occurs only if sufficient WM resource is accessible by LTM reactivation. PMID- 29582390 TI - Effects of absolute luminance and luminance contrast on visual search in low mesopic environments. AB - Diverse adaptive visual processing mechanisms allow us to complete visual search tasks in a wide visual photopic range (>0.6 cd/m2). Whether search strategies or mechanisms known from this range extend below, in the mesopic and scotopic luminance spectra (<0.6 cd/m2), has yet to be addressed. Based on a study that addressed simple target discrimination in luminance environments using contrast dependent behavioral efficiency functions, we assessed visual search in more complex-feature and conjunction-search paradigms. The results verify the previously reported deficiency windows defined by an interaction of base luminance and luminance contrast for more complex visual-search tasks. Based on significant regression analyses, a more precise definition of the magnitude of contribution of different contrast parameters. Characterized feature search patterns had approximately a 2.5:1 ratio of contribution from the Michelson contrast property relative to Weber contrast, whereas the ratio was approximately 1:1 in a serial-search condition. The results implicate near-complete magnocellular isolation in a visual-search paradigm that has yet to be demonstrated. Our analyses provide a new method of characterizing visual search and the first insight in its underlying mechanisms in luminance environments in the low mesopic and scotopic spectra.

PMID- 29582392 TI - Benefit-Risk Monitoring of Vaccines Using an Interactive Dashboard: A Methodological Proposal from the ADVANCE Project. AB - INTRODUCTION: New vaccines are launched based on their benefit-risk (B/R) profile anticipated from clinical development. Proactive post-marketing surveillance is necessary to assess whether the vaccination uptake and the B/R profile are as expected and, ultimately, whether further public health or regulatory actions are needed. There are several, typically not integrated, facets of post-marketing vaccine surveillance: the surveillance of vaccination coverage, vaccine safety, effectiveness and impact. OBJECTIVE: With this work, we aim to assess the feasibility and added value of using an interactive dashboard as a potential methodology for near real-time monitoring of vaccine coverage and pre-specified health benefits and risks of vaccines. METHODS: We developed a web application with an interactive dashboard for B/R monitoring. The dashboard is demonstrated using simulated electronic healthcare record data mimicking the introduction of rotavirus vaccination in the UK. The interactive dashboard allows end users to select certain parameters, including expected vaccine effectiveness, age groups, and time periods and allows calculation of the incremental net health benefit (INHB) as well as the incremental benefit-risk ratio (IBRR) for different sets of preference weights. We assessed the potential added value of the dashboard by user testing amongst a range of stakeholders experienced in the post-marketing monitoring of vaccines. RESULTS: The dashboard was successfully implemented and demonstrated. The feedback from the potential end users was generally positive, although reluctance to using composite B/R measures was expressed. CONCLUSION: The use of interactive dashboards for B/R monitoring is promising and received support from various stakeholders. In future research, the use of such an interactive dashboard will be further tested with real-life data as opposed to simulated data.

AB - INTRODUCTION: Food supplements containing red yeast rice (RYR) are proposed as an alternative in statin-intolerant patients, although they actually contain natural statin(s) and their safety in clinical practice is still incompletely characterized. We described and compared adverse events (AEs) associated with RYR products submitted to reporting systems maintained by the Food and Drug Administration (FDA), with a focus on liver and muscular events. METHODS: We extracted RYR-related AEs from the FDA Adverse Event Reporting System (FAERS) [first quarter (Q1)-2004 to Q2-2016], a drug-based archive, and the Center for Food Safety and Applied Nutrition Adverse Event Reporting System (CAERS) (Q1-2004 to Q1-2017). Disproportionality via reporting odds ratio (ROR) with 95% confidence interval (CI) calculation and case-by-case inspection were performed, with a focus on muscular and hepatic AEs. RESULTS: One thousand three hundred AEs were extracted from FAERS (RYR mainly reported as a concomitant agent), whereas only 159 AEs were found in CAERS (RYR recorded mainly as a suspect agent). In FAERS, a large number of reports emerged for "general disorders and administration site conditions," whereas CAERS received also a high number of reports for "investigations" and "musculoskeletal and connective tissue disorders". Disproportionality analyses confirmed higher reporting of serious muscular and liver injuries: in FAERS, five cases of hepatic disorders (ROR = 13.71; 95% CI 5.44-34.57); in CAERS, 27 cases of rhabdomyolysis/myopathy (8.44; 5.44-13.10). CONCLUSIONS: Notwithstanding recognized limitations, these findings strengthen the importance of exploring multiple databases in safety assessment of RYR products, which should be monitored by clinicians for muscular and hepatic safety, and call for urgent review by policymakers to harmonize their regulatory status.

AB - INTRODUCTION: The epidemic of prescription opioid overdose and mortality parallels the dispensing rates of prescription opioids, and the availability of increasingly potent opioid analgesics. OBJECTIVE: The common assumption that more potent opioid analgesics are associated with higher rates of adverse outcomes has not been adequately substantiated. We compared the rate of serious adverse events among commonly prescribed opioid analgesics of varying potency. METHODS: Serious adverse events (SAEs; defined as death, major medical effect, or hospitalization) resulting from exposure to tablets containing seven opioid analgesics (oxycodone, hydrocodone, morphine, hydromorphone, oxymorphone, tapentadol, and tramadol) captured by the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS(r)) System Poison Center Program were evaluated from 2010 through 2016. Rates of SAEs were adjusted for availability through outpatient dispensing data and regressed on morphine milligram equivalents (MME). RESULTS: There were 19,480 cases of SAE during the 7-year study period. Hydrocodone and oxycodone contributed to 77% of SAE cases. Comparing rates of outcome by relative potency, a hierarchy was observed with hydromorphone (8.02 SAEs/100 kg) and tapentadol (0.27 SAE/100 kg) as the highest and lowest rates, reflecting a 30-fold difference among individual opioid products. SAE rate and potency were related linearly-SAEs increased 2.04 per 100 kg drug dispensed for each 1-unit rise in MME (p = 0.004). Linear regression of SAE/100 kg drug dispensed and drug potency identified that MME comprised 96% of the variation observed. In contrast, potency did not explain variation seen using other study denominators (prescriptions dispensed, dosage units dispensed, and the number of individuals filling a prescription). CONCLUSIONS AND RELEVANCE: Potency of a prescription opioid analgesic demonstrates a significant, highly positive linear relationship with exposures resulting in SAEs per 100 kg drug dispensed reported to poison centers. Potency should be carefully considered from both individual provider and public health perspectives.

AB - The aim of this study was to evaluate in an experimental model of aortic valve (AV) stenosis the effectiveness of zoledronate on the inhibition of calcification. Sixteen New Zealand rabbits were placed on vitamin D-enriched diet for 3 weeks. All animals underwent PET/CT at baseline and before euthanasia to assess calcification. Thereafter, the AVs of eight animals were treated with local delivery of 500 MUg/l zoledronate. A placebo mixture was administered in the remaining eight animals. Standardized uptake values were corrected for blood pool activity, providing mean tissue to background ratios (TBRmean). In the zoledronate group, there was no progression of AV calcification (TBRmean 1.20 +/- 0.12 vs 1.17 +/- 0.78,p = 0.29), while AV calcification progressed in the placebo group (1.22 +/- 0.15 vs 1.53 +/- 0.23,p = 0.006). Ascending aorta (AA) calcification progressed in both zoledronate and placebo groups. Histology confirmed the results of the PET/CT. Inhibition of AV calcification by local delivery of zoledronate is feasible and effective. PMID- 29582396 TI - The Effects of Non-selective Dopamine Receptor Activation by Apomorphine in the Mouse Hippocampus. AB - Apomorphine is a dopamine receptor agonist that activates D1-D5 dopamine receptors and that is used to treat Parkinson's disease (PD). However, the effect of apomorphine on non-motor activity has been poorly studied, and likewise, the effects of dopaminergic activation in brain areas that do not fulfill motor functions are unclear. The aim of this study was to determine how dopamine receptor activation affects behavior, as well as plasticity, morphology, and oxidative stress in the hippocampus. Adult mice were chronically administered apomorphine (1 mg/kg for 15 days), and the effects on memory and learning, synaptic plasticity, dendritic length, inflammatory responses, and oxidative stress were evaluated. Apomorphine impaired learning and long-term memory in mice, as evaluated in the Morris water maze test. In addition, electrophysiological recording of field excitatory postsynaptic potentials (fEPSP) indicated that the long-term potentiation (LTP) of synaptic transmission in the CA1 region of the hippocampus was fully impaired by apomorphine. In addition, a Sholl analysis of Golgi-Cox stained neurons showed that apomorphine reduced the total length of dendrites in the CA1 region of the hippocampus. Finally, there were more reactive astrocytes and oxidative stress biomarkers in mice administered apomorphine, as measured by GFAP immunohistochemistry and markers of redox balance, respectively. Hence, the non-selective activation of dopaminergic receptors in the hippocampus by apomorphine triggers deficiencies in learning and memory, it prevents LTP, reduces dendritic length, and provokes neuronal damage. PMID- 29582397 TI - Chronic Hippocampal Expression of Notch Intracellular Domain Induces Vascular Thickening, Reduces Glucose Availability, and Exacerbates Spatial Memory Deficits in a Rat Model of Early Alzheimer. AB - The specific roles of Notch in progressive adulthood neurodegenerative disorders have begun to be unraveled in recent years. A number of independent studies have shown significant increases of Notch expression in brains from patients at later stages of sporadic Alzheimer's disease (AD). However, the impact of Notch canonical signaling activation in the pathophysiology of AD is still elusive. To further investigate this issue, 2-month-old wild-type (WT) and hemizygous McGill R-Thy1-APP rats (Tg(+/-)) were injected in CA1 with lentiviral particles (LVP) expressing the transcriptionally active fragment of Notch, known as Notch Intracellular Domain (NICD), (LVP-NICD), or control lentivirus particles (LVP-C). The Tg(+/-) rat model captures presymptomatic aspects of the AD pathology, including intraneuronal amyloid beta (Abeta) accumulation and early cognitive deficits. Seven months after LVP administration, Morris water maze test was performed, and brains isolated for biochemical and histological analysis. Our results showed a learning impairment and a worsening of spatial memory in LVP NICD- as compared to LVP-C-injected Tg(+/-) rats. In addition, immuno histochemistry, ELISA multiplex, Western blot, RT-qPCR, and 1H-NMR spectrometry of cerebrospinal fluid (CSF) indicated that chronic expression of NICD promoted hippocampal vessel thickening with accumulation of Abeta in brain microvasculature, alteration of blood-brain barrier (BBB) permeability, and a decrease of CSF glucose levels. These findings suggest that, in the presence of early Abeta pathology, expression of NICD may contribute to the development of microvascular abnormalities, altering glucose transport at the BBB with impact on early decline of spatial learning and memory. PMID- 29582398 TI - The Synthetic Steroid Tibolone Decreases Reactive Gliosis and Neuronal Death in the Cerebral Cortex of Female Mice After a Stab Wound Injury. AB - Previous studies have shown that estradiol reduces reactive gliosis after a stab wound injury in the cerebral cortex. Since the therapeutic use of estradiol is limited by its peripheral hormonal effects, it is of interest to determine whether synthetic estrogenic compounds with tissue-specific actions regulate reactive gliosis. Tibolone is a synthetic steroid that is widely used for the treatment of climacteric symptoms and/or the prevention of osteoporosis. In this study, we have assessed the effect of tibolone on reactive gliosis in the cerebral cortex after a stab wound brain injury in ovariectomized adult female mice. By 7 days after brain injury, tibolone reduced the number of glial fibrillary acidic protein (GFAP) immunoreactive astrocytes, the number of ionized calcium binding adaptor molecule 1 (Iba1) immunoreactive microglia, and the number of microglial cells with a reactive phenotype in comparison to vehicle injected animals. These effects on gliosis were associated with a reduction in neuronal loss in the proximity to the wound, suggesting that tibolone exerts beneficial homeostatic actions in the cerebral cortex after an acute brain injury. PMID- 29582399 TI - Perinatal Asphyxia and Brain Development: Mitochondrial Damage Without Anatomical or Cellular Losses. AB - Perinatal asphyxia remains a significant cause of neonatal mortality and is associated with long-term neurodegenerative disorders. In the present study, we evaluated cellular and subcellular damages to brain development in a model of mild perinatal asphyxia. Survival rate in the experimental group was 67%. One hour after the insult, intraperitoneally injected Evans blue could be detected in the fetuses' brains, indicating disruption of the blood-brain barrier. Although brain mass and absolute cell numbers (neurons and non-neurons) were not reduced after perinatal asphyxia immediately and in late brain development, subcellular alterations were detected. Cortical oxygen consumption increased immediately after asphyxia, and remained high up to 7 days, returning to normal levels after 14 days. We observed an increased resistance to mitochondrial membrane permeability transition, and calcium buffering capacity in asphyxiated animals from birth to 14 days after the insult. In contrast to ex vivo data, mitochondrial oxygen consumption in primary cell cultures of neurons and astrocytes was not altered after 1% hypoxia. Taken together, our results demonstrate that although newborns were viable and apparently healthy, brain development is subcellularly altered by perinatal asphyxia. Our findings place the neonate brain mitochondria as a potential target for therapeutic protective interventions.

PMID- 29582400 TI - Enhancing Endogenous Nitric Oxide by Whole Body Periodic Acceleration Elicits Neuroprotective Effects in Dystrophic Neurons. AB - We have previously shown that inadequate dystrophin in cortical neurons in mdx mice is associated with age-dependent dyshomeostasis of resting intracellular Ca2+ ([Ca2+]i) and Na+ ([Na+]i), elevated reactive oxygen species (ROS) production, increase in neuronal damage and cognitive deficit. In this study, we assessed the potential therapeutic properties of the whole body periodic acceleration (pGz) to ameliorate the pathology observed in cortical neurons from the mdx mouse. pGz adds small pulses to the circulation, thereby increasing pulsatile shear stress to the vascular endothelium, which in turn increases production of nitric oxide (NO). We found [Ca2+]i and [Na+]i overload along with reactive oxygen species (ROS) overproduction in mdx neurons and cognitive dysfunction. mdx neurons showed increased activity of superoxide dismutase, glutathione peroxidase, malondialdehyde, and calpain as well as decreased cell viability. mdx neurons were more susceptible to hypoxia-reoxygenation injury than WT. pGz ameliorated the [Ca2+]i, and [Na+]i elevation and ROS overproduction and further increased the activities of superoxide dismutase, glutathione peroxidase and reduced the malondialdehyde and calpains. pGz diminished cell damage and elevated [Ca2+]i during hypoxia-reoxygenation and improved cognitive function in mdx mice. Moreover, pGz upregulated the expression of utrophin, dystroglycan-beta and CAPON, constitutive nitric oxide synthases, prosaposin, brain-derived neurotrophic, and glial cell line-derived neurotrophic factors. The present study demonstrated that pGz is an effective therapeutic approach to improve mdx neurons function, including cognitive functions. PMID- 29582401 TI - TRPV4: a Sensor for Homeostasis and Pathological Events in the CNS. AB - Transient receptor potential vanilloid type 4 (TRPV4) was originally described as a calcium-permeable nonselective cation channel. TRPV4 is now recognized as a polymodal ionotropic receptor: it is a broadly expressed, nonselective cation channel (permeable to calcium, potassium, magnesium, and sodium) that plays an important role in a multitude of physiological processes. TRPV4 is involved in maintaining homeostasis, serves as an osmosensor and thermosensor, can be activated directly by endogenous or exogenous chemical stimuli, and can be activated or sensitized indirectly via intracellular signaling pathways. Additionally, TRPV4 is upregulated in a variety of pathological conditions. In this review, we focus on the role of TRPV4 in mediating homeostasis and pathological events in the central nervous system (CNS). This review is composed of three parts. Section 1 describes the role of TRPV4 in maintaining homeostatic processes, including the volume of body water, ionic concentrations, volume, and the temperature. Section 2 describes the effects of activation and inhibition of TRPV4 in the CNS. Section 3 focuses on the role of TRPV4 during pathological events in CNS. PMID- 29582403 TI - Medications and Prescribing Patterns as Factors Associated with Hospitalizations from Long-Term Care Facilities: A Systematic Review. AB - BACKGROUND: Residents of long-term care facilities (LTCFs) are at high risk of hospitalization. Medications are a potentially modifiable risk factor for hospitalizations. OBJECTIVE: Our objective was to systematically review the association between medications or prescribing patterns and hospitalizations from LTCFs. METHODS: We searched MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and International Pharmaceutical Abstracts (IPA) from inception to August 2017 for longitudinal studies reporting associations between medications or prescribing patterns and hospitalizations. Two independent investigators completed the study selection, data extraction and quality assessment using the Joanna Briggs Institute Critical Appraisal Tools. RESULTS: Three randomized controlled trials (RCTs), 22 cohort studies, five case control studies, one case-time-control study and one case-crossover study, investigating 13 different medication classes and two prescribing patterns were included. An RCT demonstrated that high-dose influenza vaccination reduced all cause hospitalization compared with standard-dose vaccination (risk ratio [RR] 0.93; 95% confidence interval [CI] 0.88-0.98). Another RCT found no difference in hospitalization rates between oseltamivir as influenza treatment and oseltamivir as treatment plus prophylaxis (treatment = 4.7%, treatment and prophylaxis = 3.5%; p = 0.7). The third RCT found no difference between multivitamin/mineral supplementation and hospitalization (odds ratio [OR] 0.94; 95% CI 0.74-1.20) or emergency department visits (OR 1.05; 95% CI 0.76-1.47). Two cohort studies demonstrated influenza vaccination reduced hospitalization. Four studies suggested polypharmacy and potentially inappropriate medications (PIMs) increased all-cause hospitalization. However, associations between polypharmacy (two studies), PIMs (one study) and fall-related hospitalizations were inconsistent. Inconsistent associations were found between psychotropic medications with all cause and cause-specific hospitalizations (11 studies). Warfarin, nonsteroidal anti-inflammatory drugs, pantoprazole and vinpocetine but not long-term acetylsalicylic acid (aspirin), statins, trimetazidine, digoxin or beta-blockers were associated with all-cause or cause-specific hospitalizations in single studies of specific resident populations. Most cohort studies assessed prevalent rather than incident medication exposure, and no studies considered time-varying medication use. CONCLUSION: High-quality evidence suggests influenza vaccination reduces hospitalization. Polypharmacy and PIMs are consistently associated with increased all-cause hospitalization. PMID- 29582405 TI - Ixazomib for Relapsed or Refractory Multiple Myeloma: Review from an Evidence Review Group on a NICE Single Technology Appraisal. AB - Ixazomib is an oral proteasome inhibitor used in combination with lenalidomide plus dexamethasone (IXA-LEN-DEX) and licensed for relapsed or refractory multiple myeloma. As part of a single technology appraisal (ID807) undertaken by the National Institute of Health and Care Excellence, the Evidence Review Group, Warwick Evidence was invited to independently review the evidence submitted by the manufacturer of ixazomib, Takeda UK Ltd. The main source of clinical effectiveness data about IXA-LEN-DEX came from the Tourmaline-MM1 randomized controlled trial in which 771 patients with relapsed or refractory multiple myeloma received either IXA-LEN-DEX or placebo-LEN-DEX as their second-, third-, or fourth-line treatment. Takeda estimated the cost effectiveness of IXA-LEN-DEX using a de-novo partitioned-survival model with three health states (pre progression, post-progression, and dead). In their first submission, this model was used to estimate the cost effectiveness of IXA-LEN-DEX vs. bortezomib plus dexamethasone (BORT-DEX) in second-line treatment, and of IXA-LEN-DEX vs. LEN-DEX in third-line treatment. To estimate the relative clinical performance of IXA-LEN DEX vs. BORT-DEX, Takeda conducted network meta-analyses for important outcomes. The network meta-analysis for overall survival was found to be flawed in several respects, but mainly because a hazard ratio input for one of the studies in the network had been inverted, resulting in a large inflation of the claimed superiority of IXA-LEN-DEX over BORT-DEX and a considerable overestimation of its cost effectiveness. In subsequent submissions, Takeda withdrew second-line treatment as an option for IXA-LEN-DEX. The manufacturer's first submission comparing IXA-LEN-DEX with LEN-DEX for third-line therapy employed Tourmaline-MM1 data from third- and fourth-line patients as proxy for a third-line population. The appraisal committee did not consider this reasonable because randomization in Tourmaline-MM1 was stratified according to one previous treatment and two or more previous treatments. A further deficiency was considered to be the manufacturer's use of interim survival data rather than the most mature data available. A second submission from the company focussed on IXA-LEN-DEX vs. LEN-DEX as third- or fourth-line treatment (the two or more previous lines population) and a new patient access scheme was introduced. Covariate modeling of survival outcomes was proposed using the most mature survival data. The Evidence Review Group's main criticisms of the new evidence included: the utility associated with the pre progression health state was overestimated, treatment costs of ixazomib were underestimated, survival models were still associated with great uncertainty, leading to clinically implausible anomalies and highly variable incremental cost effectiveness ratio estimates, and the company had not explored a strong assumption that the survival benefit of IXA-LEN-DEX over LEN-DEX would be fully maintained for a further 22 years beyond the observed data, which encompassed only approximately 2.5 years of observation. The appraisal committee remained unconvinced that ixazomib represented a cost-effective use of National Health Service resources. Takeda's third submission offered new base-case parametric models for survival outcomes, a new analysis of utilities, and proposed a commercial access agreement. In a brief critique of the third submission, the Evidence Review Group agreed that the selection of appropriate survival models was problematic and at the request of the National Institute for Health Care and Excellence investigated external sources of evidence regarding survival outcomes. The Evidence Review Group considered that some cost and utility estimates in the submission may have remained biased in favor of ixazomib. As a result of their third appraisal meeting, the committee judged that for the two to three prior therapies population, and at the price agreed in a commercial access agreement, ixazomib had the potential to be cost effective. It was referred to the Cancer Drugs Fund so that further data could accrue with the aim of diminishing the clinical uncertainties. PMID- 29582404 TI - Newer Antiepileptic Drugs for Status Epilepticus in Adults: What's the Evidence? AB - Status epilepticus (SE) is one of the most frequent neurological emergencies. Despite this, understanding of its pathophysiology and evidence regarding its management is limited. Rapid, effective, and well-tolerated treatment to achieve seizure cessation is advocated to prevent brain damage or potentially lethal outcomes. The last two decades have witnessed an exponential increase in the number of available antiepileptic drugs (AEDs). These compounds, especially lacosamide and levetiracetam, in view of their intravenous formulation, have been increasingly prescribed in SE. These and other newer AEDs present a promising profile in terms of tolerability, with few centrally depressive effects, favorable pharmacokinetic properties, and fewer drug interactions than classical AEDs; conversely, they are more expensive. There is still no clear evidence to suggest a specific beneficial impact of newer AEDs on SE outcome, preventing any strong recommendation regarding their prescription in SE. Further comparative studies are urgently required to clarify their place and optimal use in the armamentarium of SE treatment. PMID- 29582406 TI - Reslizumab for Treating Asthma with Elevated Blood Eosinophils Inadequately Controlled by Inhaled Corticosteroids: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - As part of the National Institute for Health and Care Excellence (NICE) Single Technology Appraisal (STA) process, the manufacturer of reslizumab (Teva) submitted evidence for its clinical and cost effectiveness for the treatment of eosinophilic asthma inadequately controlled by inhaled corticosteroids. NICE commissioned Southampton Health Technology Assessments Centre (SHTAC) as an independent Evidence Review Group (ERG) to provide a critique of the manufacturer's submitted evidence. Reslizumab is compared with best standard of care and omalizumab, for a small 'overlap' population of patients who have both eosinophilic and IgE-mediated severe asthma. This paper provides a summary of the ERG's review of the manufacturer's submission, and summarises the NICE Appraisal Committee's subsequent guidance (issued in August 2017). The ERG considered that there were limitations in the approach proposed by the manufacturer for the exacerbation rate and the utility for severe exacerbation. The company amended their initial analysis, following comments from the ERG and the NICE committee, whereby the incremental cost effectiveness ratio was L29,870 per QALY gained for reslizumab compared with best standard care. The NICE Appraisal Committee (AC) concluded that reslizumab was recommended as an option for the treatment of severe eosinophilic asthma that is inadequately controlled in adults despite maintenance therapy with high-dose inhaled corticosteroids plus another drug, only if (1) the blood eosinophil count has been recorded as 400 cells per microlitre or more and (2) the patient has had three or more asthma exacerbations in the past 12 months, and (3) the company provides reslizumab with the discount agreed in the patient access scheme. PMID- 29582407 TI - In vitro activity of linezolid, daptomycin and N-acetylcysteine agents on Staphylococcus aureus biofilms in the ventriculoperitoneal shunt model. AB - AIM: In this study, the effect of N-acetylcysteine (NAC) alone and in combination with linezolid (LIN) and daptomycin (DAPT) was examined on methicillin-sensitive Staphylococcus aureus (MSSA) biofilm formation. MATERIAL AND METHODS: Twelve groups (each containing six molds) of standard ventriculoperitoneal shunts were infected with MSSA. By using microbiological and electron microscopic evaluation methods, NAC was evaluated, alone and in combination with DAPT and LIN, in terms of preventing and eliminating biofilm capacity. The effect of NAC alone and in combination with DAPT and LIN were shown by microbial counts and electron microscopic observation. RESULTS: The results showed no significant difference in biofilm formation in shunts after different antibiotic treatments. However, the combination of NAC and DAPT had the highest bactericidal effects of all the groups. CONCLUSION: The resistance of bacteria and the dose-dependent effects of antibiotics can be considered. PMID- 29582408 TI - Strategies for the prevention of postoperative pulmonary complications. PMID- 29582409 TI - EphA2 receptor is a key player in the metastatic onset of Ewing sarcoma. AB - Ewing sarcoma (ES) is the second most common bone malignancy affecting children and young adults with poor prognosis due to high metastasis incidence. Our group previously described that EphA2, a tyrosine kinase receptor, promotes angiogenesis in Ewing sarcoma (ES) cells via ligand-dependent signaling. Now we wanted to explore EphA2 ligand-independent activity, controlled upon phosphorylation at S897 (p-EphA2S897 ), as it has been linked to metastasis in several malignancies. By reverse genetic engineering we explored the phenotypic changes after EphA2 removal or reintroduction. Gene expression microarray was used to identify key players in EphA2 signaling. Mice were employed to reproduce metastatic processes from orthotopically implanted engineered cells. We established a correlation between ES cells aggressiveness and p-EphA2S897 . Moreover, stable overexpression of EphA2 in low EphA2 expression ES cells enhanced proliferation and migration, but not a non-phosphorylable mutant (S987A). Consistently, silencing of EphA2 reduced tumorigenicity, migration and invasion in vitro, and lung metastasis incidence in experimental and spontaneous metastasis assays in vivo. A gene expression microarray revealed the implication of EphA2 in cell signaling, cellular movement and survival. ADAM19 knockdown by siRNA technology strongly reproduced the negative effects on cell migration observed after EphA2 silencing. Altogether, our results suggest that p-EphA2S897 correlates with aggressiveness in ES, so blocking its function may be a promising treatment. PMID- 29582410 TI - National Prescribing Trends for High-Risk Anticholinergic Medications in Older Adults. AB - OBJECTIVES: To estimate prescribing tends of and correlates independently associated with high-risk anticholinergic prescriptions in adults aged 65 and older in office-based outpatient visits. DESIGN: Repeated cross-sectional analysis. SETTING: National Ambulatory Medical Care Survey (NAMCS). PARTICIPANTS: A national sample of office-based physician visits by adults aged 65 and older from 2006 to 2015 (n=96,996 unweighted). MEASUREMENTS: Prescriptions of high-risk anticholinergics, regardless of indication, were identified, and overall prescribing trends were estimated from 2006 to 2015. Stratified analyses of prescribing trends according to physician specialty and anticholinergic drug class were also performed. We used a multivariable logistic regression analysis to estimate the odds of high-risk anticholinergic prescription. RESULTS: Between 2006 and 2015, a high-risk anticholinergic prescription was listed for 5,876 (6.2%) 96,996 visits of older adults, representative of 14.6 million total visits nationally. The most common drug classes were antidepressants, antimuscarinics, and antihistamines, which accounted for more than 70% of prescribed anticholinergics. Correlates independently associated with greater odds of receiving a high-risk anticholinergic prescription were female sex, the Southern geographic region, specific physician specialties (e.g., psychiatry, urology), receipt of 6 or more concomitantly prescribed medications, and related clinical diagnoses (e.g., urinary continence) (p<.01 for all). CONCLUSION: The prevalence of high-risk anticholinergic prescriptions was stable over time but varied according to physician specialty and drug class. Quality prescribing should be promoted because safer alternatives are available. PMID- 29582411 TI - Influence of endometrial thickness on pregnancy rates in modified natural cycle frozen-thawed embryo transfer. AB - INTRODUCTION: Pregnancy after frozen-thawed embryo transfer (FET) is a multifactorial process. Although embryo quality is a key factor in determining pregnancy, other factors, including maternal determinants, are also considered to be predictive. Even though an association between endometrial thickness measured by transvaginal ultrasound and pregnancy rates has been reported in patients undergoing various assisted reproductive technology treatments, whether endometrial thickness predicts achieving pregnancy after natural cycle FET (NC FET) remains unclear. MATERIAL AND METHODS: In this cohort study, 463 patients allocated to the modified NC-FET (mNC-FET) arm of a previously published randomized controlled trial were included. Monitoring in mNC-FET cycles consisted of regular ultrasound scans, measuring both dominant follicle and endometrial thickness. When the dominant follicle reached a size of 16-20 mm, an injection of human chorionic gonadotrophin was administered and embryo thawing and transfer planned. No minimal endometrial thickness was defined below which transfer was to be deferred. The primary endpoint was ongoing pregnancy rate. RESULTS: Overall, the ongoing pregnancy rate per started FET cycle was 12.5%. Multivariate regression analyses showed that embryo quality was the only significant predictor for ongoing pregnancy. Mean endometrial thickness did not differ between patients achieving ongoing pregnancy and those who did not (9.0 vs. 8.8 mm, p = 0.4). Comparable results were obtained with regard to clinical pregnancy, live birth and miscarriage rates. The area under the receiver operator curve was 0.5, indicating little discriminatory value of endometrial thickness. CONCLUSIONS: Given that endometrial thickness was not found to be predictive of pregnancy after mNC-FET, cancellation based on endometrial thickness alone may not be justified. PMID- 29582412 TI - Diabetes and smoking as predictors of cancer in Indigenous adults from rural and remote communities of North Queensland - A 15-year follow up study. AB - Indigenous Australians generally have a poor health status and an elevated cancer mortality that has increased in recent decades. A cohort of 2,273 Aboriginal and Torres Strait Islander (TSI) adults (18+ years) from 26 remote communities in far North Queensland, who were initially free of cancer, were followed-up for an average of 15 years. The associations of baseline anthropometric, biochemical and behavioural factors with cancer incidence were investigated using competing risk survival analysis. The age-standardised incidence (all cancers) was 5.2 cases/1,000 person-years (pys) (95% CI 4.1-6.6). Liver/bile duct and lung were the most common cancer sites. Overall cancer incidence was significantly higher in TSIs than Aboriginal people. The baseline prevalence of diabetes was 15.6% in Aboriginal and 25.6% in TSI people. The smoking rate of 59.8% for Aboriginal people was higher than the rate of 45.2% for TSIs. At follow-up, the adjusted sub hazard ratios (SHRs) of diabetes for all cancers combined were 1.8 (95% CI, 1.3 2.6), and for digestive system cancers, 2.3 (95% CI, 1.2-4.4). Smokers had a 60% higher risk (SHR 1.6, 95% CI: 1.1-2.0) for all cancers combined and a fourfold risk (SHR 3.7, 95% CI 1.7-8.0) for lung cancers when compared to non-smokers, regardless of age, sex and ethnicity. The most common cancers encountered by this Indigenous cohort and their consequences are potentially preventable in Indigenous Australians by effective management of highly prevalent modifiable risks in primary service settings, screening participation and arranging for good access to treatment services. PMID- 29582413 TI - Dietary docosahexaenoic acid supplementation enhances expression of fatty acid binding protein 5 at the blood-brain barrier and brain docosahexaenoic acid levels. AB - The cytoplasmic trafficking of docosahexaenoic acid (DHA), a cognitively beneficial fatty acid, across the blood-brain barrier (BBB) is governed by fatty acid-binding protein 5 (FABP5). Lower levels of brain DHA have been observed in Alzheimer's disease (AD), which is associated with diminished BBB expression of FABP5. Therefore, up-regulating FABP5 expression at the BBB may be a novel approach for enhancing BBB transport of DHA in AD. DHA supplementation has been shown to be beneficial in various mouse models of AD, and therefore, the aim of this study was to determine whether DHA has the potential to up-regulate the BBB expression of FABP5, thereby enhancing its own uptake into the brain. Treating human brain microvascular brain endothelial (hCMEC/D3) cells with the maximum tolerable concentration of DHA (12.5 MUM) for 72 h resulted in a 1.4-fold increase in FABP5 protein expression. Associated with this was increased expression of fatty acid transport proteins 1 and 4. To study the impact of dietary DHA supplementation, 6- to 8-week-old C57BL/6 mice were fed with a control diet or a DHA-enriched diet for 21 days. Brain microvascular FABP5 protein expression was up-regulated 1.7-fold in mice fed the DHA-enriched diet, and this was associated with increased brain DHA levels (1.3-fold). Despite an increase in brain DHA levels, reduced BBB transport of 14 C-DHA was observed over a 1 min perfusion, possibly as a result of competitive binding to FABP5 between dietary DHA and 14 C-DHA. This study has demonstrated that DHA can increase BBB expression of FABP5, as well as fatty acid transporters, overall increasing brain DHA levels. PMID- 29582414 TI - The novel MU-opioid receptor agonist PZM21 depresses respiration and induces tolerance to antinociception. AB - BACKGROUND AND PURPOSE: PZM21 is a novel MU-opioid receptor ligand that has been reported to induce minimal arrestin recruitment and be devoid of the respiratory depressant effects characteristic of classical MU receptor ligands such as morphine. We have re-examined the signalling profile of PZM21 and its ability to depress respiration. EXPERIMENTAL APPROACH: G protein (Gi ) activation and arrestin-3 translocation were measured in vitro, using BRET assays, in HEK 293 cells expressing MU receptors. Respiration (rate and tidal volume) was measured in awake, freely moving mice by whole-body plethysmography, and antinociception was measured by the hot plate test. KEY RESULTS: PZM21 (10-9 - 3 * 10-5 M) produced concentration-dependent Gi activation and arrestin-3 translocation. Comparison with responses evoked by morphine and DAMGO revealed that PZM21 was a low efficacy agonist in both signalling assays. PZM21 (10-80 mg.kg-1 ) depressed respiration in a dose-dependent manner. The respiratory depression was due to a decrease in the rate of breathing not a decrease in tidal volume. On repeated daily administration of PZM21 (twice daily doses of 40 mg.kg-1 ), complete tolerance developed to the antinociceptive effect of PZM21 over 3 days but no tolerance developed to its respiratory depressant effect. CONCLUSION AND IMPLICATIONS: These data demonstrate that PZM21 is a low efficacy MU receptor agonist for both G protein and arrestin signalling. Contrary to a previous report, PZM21 depresses respiration in a manner similar to morphine, the classical opioid receptor agonist.

PMID- 29582416 TI - Body fat reduction without cardiovascular changes in mice after oral treatment with the MAO inhibitor phenelzine. AB - BACKGROUND AND PURPOSE: Phenelzine is an antidepressant drug known to increase the risk of hypertensive crisis when dietary tyramine is not restricted. However, this MAO inhibitor inhibits other enzymes not limited to the nervous system. Here we investigated if its antiadipogenic and antilipogenic effects in cultured adipocytes could contribute to decreased body fat in vivo, without unwanted hypertensive or cardiovascular effects. EXPERIMENTAL APPROACH: Mice were fed a standard chow and given 0.028% phenelzine in drinking water for 12 weeks. Body composition was determined by NMR. Cardiovascular dysfunction was assessed by heart rate variability analyses and by evaluation of cardiac oxidative stress markers. MAO activity, hydrogen peroxide release and triacylglycerol turnover were assayed in white adipose tissue (WAT), alongside determination of glucose and lipid circulating levels. KEY RESULTS: Phenelzine-treated mice exhibited lower body fat content, subcutaneous WAT mass and lipid content in skeletal muscles than control, without decreased body weight gain or food consumption. A modest alteration of cardiac sympathovagal balance occurred without depressed aconitase activity. In WAT, phenelzine impaired the lipogenic but not the antilipolytic actions of insulin, MAO activity and hydrogen peroxide release. Phenelzine treatment lowered non-fasting blood glucose and phosphoenolpyruvate carboxykinase expression. In vitro, high doses of phenelzine decreased both lipolytic and lipogenic responses in mouse adipocytes. CONCLUSION AND IMPLICATIONS: As phenelzine reduced body fat content without affecting cardiovascular function in mice, it may be of benefit in the treatment of obesity associated complications, with the precautions of use recommended for antidepressant therapy. PMID- 29582418 TI - Management of uterine ectopic pregnancy - local vs. systemic methotrexate. AB - INTRODUCTION: The aim of this study was to compare ultrasound-guided local methotrexate (MTX) vs. systemic methotrexate in uterine ectopic pregnancy regarding the beta human chorionic gonadotropin (hCG) clearance duration. MATERIAL AND METHODS: Patients with interstitial pregnancy, cervical pregnancy or cesarean scar pregnancy were included. Methotrexate was administered locally ultrasound-guided (25 mg methotrexate fixed dose) or systemically (intramuscular; 50 mg/m2 body weight). Beta hCG clearance duration in days formed the main outcome measure. RESULTS: Forty-six patients with uterine ectopic pregnancy were included. The mean estimated beta hCG clearance duration was 29.2 days longer in patients with local methotrexate compared with systemic methotrexate (64.7 vs. 31.5 days, respectively; p = 0.026). There was no significant difference between local vs. systemic methotrexate regarding adverse events such as bleeding (p = 0.376), pain (p = 0.146) or secondary surgery (p = 0.631). There was no association of initial beta hCG levels (p = 0.746), initial progesterone levels (p = 0.870) or patients' age (p = 0.604) and the beta hCG clearance duration. No significant difference in beta hCG clearance duration comparing local methotrexate injection with aspiration vs. local methotrexate injection without aspiration could be found (mean 49.4 and 71.6 days, respectively, p = 0.225). CONCLUSIONS: In patients with uterine ectopic pregnancies, the mean estimated beta hCG clearance duration was 29.2 days longer when applying local methotrexate compared with systemic methotrexate. PMID- 29582417 TI - Analysis of the distribution of spinal NOP receptors in a chronic pain model using NOP-eGFP knock-in mice. AB - BACKGROUND AND PURPOSE: The nociceptin/orphanin FQ opioid peptide (NOP) receptor system plays a significant role in the regulation of pain. This system functions differently in the spinal cord and brain. The mechanism by which the NOP receptor agonists regulate pain transmission in these regions is not clearly understood. Here, we investigate the peripheral and spinal NOP receptor distribution and antinociceptive effects of intrathecal nociceptin/orphanin FQ (N/OFQ) in chronic neuropathic pain. EXPERIMENTAL APPROACH: We used immunohistochemistry to determine changes in NOP receptor distribution triggered by spinal nerve ligation (SNL) using NOP-eGFP knock-in mice. Antinociceptive effects of intrathecal N/OFQ on SNL-mediated allodynia and heat/cold hyperalgesia were assessed in wild-type mice. KEY RESULTS: NOP-eGFP immunoreactivity was decreased by SNL in the spinal laminae I and II outer, regions that mediate noxious heat stimuli. In contrast, immunoreactivity of NOP-eGFP was unchanged in the ventral border of lamina II inner, which is an important region for the development of allodynia. NOP-eGFP expression was also decreased in a large number of primary afferents in the L4 dorsal root ganglion (DRG) of SNL mice. However, SNL mice showed increased sensitivity, compared to sham animals to the effects of i.t administered N/OFQ with respect to mechanical as well as thermal stimuli. CONCLUSIONS AND IMPLICATIONS: Our findings suggest that the spinal NOP receptor system attenuates injury-induced hyperalgesia by direct inhibition of the projection neurons in the spinal cord that send nociceptive signals to the brain and not by inhibiting presynaptic terminals of DRG neurons in the superficial lamina. PMID- 29582419 TI - Synthesis and biological evaluation of novel cyclopropyl derivatives as subtype selective ligands for estrogen receptor. AB - OBJECTIVES: Tamoxifen is the most commonly used selective estrogen receptor modulators (SERMs); however, patients often develop the acquired drug resistance on tamoxifen therapy. The aim of this study was to develop new SERMs. METHODS: Several novel cyclopropyl derivatives were designed and synthesized. The binding affinities of these compounds as well as the selectivity on subtype of estrogen receptor (ER) were assessed by fluorescence polarization. The antagonistic activity was also evaluated by dual-luciferase reporter assay. KEY FINDINGS: Our data identified five compounds (9a, 9b, 9d, 9e and 9f) with a higher selectivity on ERalpha than ERbeta subtype, warranting further development as a subtype selective ER modulator. The study of antiestrogen activity also demonstrated that compounds 9a, 9c-f acted as full functional antagonists for ERalpha. These compounds had no or very low cytotoxicity. CONCLUSIONS: Although these cyclopropyl derivatives showed lower binding affinities on ERs compared to 17beta estradiol, five of these compounds exhibited binding to ERalpha only and therefore might serve as a promising lead compound for further development of novel subtype-selective SERMs. PMID- 29582420 TI - Redescription of Dekeyseria picta (Siluriformes; Loricariidae), a poorly known ancistrin from the Amazon and Orinoco Basins. AB - A re-evaluation of Dekeyseria brachyura and D. pulchra found them to be junior synonyms of D. picta, the oldest species among these congeners, based on continuous intraspecific variation in morphometrics and colour pattern. Examination of material deposited at Brazilian and Venezuelan collections, including the original type specimens of Ancistrus brachyurus and A. pictus, plus samples recently collected in the Rio Negro, Amazonas, Brazil, allowed re evaluation of the taxonomic status of D. picta and provides additional information on its distribution, habitats and reproductive strategies. PMID- 29582421 TI - The enhanced recovery after surgery (ERAS) Greenie Board: a Navy-inspired quality improvement tool. AB - The United States Navy uses a visual feedback system for pilots, named 'the Greenie Board', to improve flight manoeuvres on aircraft carriers. Given that increased compliance with enhanced recovery after surgery protocols reduces postoperative complications, we decided to apply a similar feedback system to our institutional enhanced recovery programme. We undertook a prospective 12-month audit of 194 patients assigned to our enhanced recovery programme and evaluated adherence to the anaesthesia-related components of our protocol, before and after implementing a Greenie Board. A compliance score was calculated by summing points for adherence to: intra-operative antibiotic prophylaxis; temperature management; goal-directed intravenous fluid therapy; postoperative nausea and vomiting prophylaxis; and postoperative fluid restriction. The score for each patient was then colour-coded and anonymously displayed for each anaesthetist on a Greenie Board within the operating theatre suite. Protocol adherence improved significantly following introduction, with 'Green' scores (acceptable compliance) increasing from 33% to 72% of patients (p < 0.0001). The greatest improvement was seen with anti-emetic prophylaxis (49% to 70%, p = 0.004) with a consequent reduction in postoperative nausea and vomiting (OR 0.42, 95% CI 0.19-0.88, p = 0.021). We did not observe a decrease in other postoperative complications nor hospital length of stay. We conclude that this US Navy-inspired feedback system is an easily implemented, low-cost quality improvement tool that significantly improved adherence to intra-operative components of our enhanced recovery protocol. The system lends itself to global scaling to drive quality improvement in healthcare delivery and would be suited to institutions without electronic medical records, including low-resource countries. PMID- 29582422 TI - The effect of spinal hyperbaric bupivacaine-fentanyl or hyperbaric bupivacaine on uterine tone and fetal heart rate in labouring women: a randomised controlled study. AB - The mechanism for fetal heart rate abnormalities following spinal opioids remains controversial. We evaluated uterine tone, using an intra-uterine pressure catheter, and fetal heart rate abnormalities in 30 women in spontaneous labour with cervical dilation of 3-5 cm having combined spinal-epidural analgesia. Women were randomly assigned to receive a spinal with 2.0 mg hyperbaric bupivacaine plus 15 MUg fentanyl, or 2.5 mg hyperbaric bupivacaine. The primary outcome measure was an increase > 10 mmHg in baseline uterine tone in the 30-min period following spinal injection. Only three (20%) women who had a bupivacaine-fentanyl spinal showed a > 10 mmHg increase in baseline tone vs. none who had bupivacaine (p = 0.63). The mean (SD) baseline uterine tone after the spinal injection was 13.3 (7.0) mmHg in the bupivacaine-fentanyl group and 7.7 (2.5) mmHg in the bupivacaine group (p = 0.01). Seven (47%) in the bupivacaine-fentanyl group showed new onset fetal heart rate changes during the 30-min period after the spinal, compared with two (13%) in the bupivacaine group (p = 0.04); however, these were transient and responded to intra-uterine resuscitation. Pain scores, sensory and motor block as well as neonatal outcomes were comparable between the groups. We found that raised baseline uterine tone was not more frequent when using bupivacaine-fentanyl rather than bupivacaine in the spinal component of combined spinal-epidural, although absolute values of baseline tone were higher, and fetal heart rate changes more frequent, in the former group. PMID- 29582423 TI - A PRDX1-p38alpha heterodimer amplifies MET-driven invasion of IDH-wildtype and IDH-mutant gliomas. AB - The Peroxiredoxin 1 (PRDX1) gene maps to chromosome arm 1p and is hemizygously deleted and epigenetically silenced in isocitrate dehydrogenase 1 or 2 (IDH) mutant and 1p/19q-codeleted oligodendroglial tumors. In contrast, IDH-wildtype astrocytic gliomas including glioblastomas mostly lack epigenetic silencing and express PRDX1 protein. In our study, we investigated how PRDX1 contributes to the infiltrative growth of IDH-wildtype gliomas. Focusing on p38alpha-dependent pathways, we analyzed clinical data from 133 patients of the NOA-04 trial cohort to look for differences in the gene expression profiles of gliomas with wildtype or mutant IDH. Biochemical interaction studies as well as in vitro and ex vivo migration studies were used to establish a biological role of PRDX1 in maintaining pathway activity. Whole-brain high-resolution ultramicroscopy and survival analyses of pre-clinical mouse models for IDH-wildtype gliomas were then used for in vivo confirmation. Based on clinical data, we found that the absence of PRDX1 is associated with changes in the expression of MET/HGF signaling components. PRDX1 forms a heterodimer with p38alpha mitogen-activated protein kinase 14 (MAPK14), stabilizing phospho-p38alpha in glioma cells. This process amplifies hepatocyte growth factor (HGF)-mediated signaling and stimulates actin cytoskeleton dynamics that promote glioma cell migration. Whole-brain high resolution ultramicroscopy confirms these findings, indicating that PRDX1 promotes glioma brain invasion in vivo. Finally, reduced expression of PRDX1 increased survival in mouse glioma models. Thus, our preclinical findings suggest that PRDX1 expression levels may serve as a molecular marker for patients who could benefit from targeted inhibition of MET/HGF signaling. PMID- 29582424 TI - Antinociceptive and anti-inflammatory effects of 1,2-bis-(4 methoxyphenylselanyl) styrene in mice: involvement of the serotonergic system. AB - BACKGROUND: Pain is one of the most prevalent, costly and disabling conditions that reduces quality of life. Although there are many analgesics available, there is some concern regarding their efficacy, safety and side effects. Organic selenium compounds are attractive targets of various research groups due to their pharmacological properties. OBJECTIVES: The aim of this study was to evaluate the antinociceptive and anti-inflammatory activity of 1,2-bis-(4 methoxyphenylselanyl) styrene (BMOSE) in mice, as well as to investigate the mechanism involved in the antinociceptive effect. METHODS: The animals were submitted to the formalin and glutamate tests. The assessment of the possible involvement of the serotonergic system in BMOSE antinociceptive activity was performed using the glutamate test. Also, we investigated the possible toxicity of the compound. KEY FINDINGS: 1,2-bis-(4-methoxyphenylselanyl) styrene (0.1-50 mg/kg, i.g.) was efficient in avoiding nociception induced by glutamate and formalin and also reduced paw oedema. The possible involvement of 5-HT3 serotoninergic receptor antagonist ondansetron blocked the antinociceptive effect of BMOSE. The acute toxicity assays did not show any toxicity related to the administration of BMOSE (200 mg/kg). CONCLUSIONS: It is possible to conclude that BMOSE has both antinociceptive and anti-inflammatory activity, and the serotoninergic system, more specifically, the 5-HT3 receptor, is involved in the effect. PMID- 29582425 TI - Good social skills despite poor theory of mind: exploring compensation in autism spectrum disorder. AB - BACKGROUND: It is proposed that some individuals with Autism Spectrum Disorder (ASD) can 'compensate' for their underlying difficulties (e.g. in theory of mind; ToM), thus demonstrating relatively few behavioural symptoms, despite continued core cognitive deficits. The mechanisms underpinning compensation are largely unexplored, as is its potential impact on mental health. This study aimed to estimate compensation patterns in ASD, by contrasting overt social behaviour with ToM task performance, in order to compare the characteristics of 'Low' and 'High' Compensators. METHODS: A total of 136 autistic adolescents, from the ongoing Social Relationships Study, completed a range of cognitive tasks, the Autistic Diagnostic Observation Schedule (ADOS) and a self-report anxiety questionnaire. Participants were assigned compensation group status; High Compensators demonstrated good ADOS scores despite poor ToM performance, while Low Compensators demonstrated similarly poor ToM, accompanied by poor ADOS scores. RESULTS: High Compensators demonstrated better IQ and executive function (EF), but greater self-reported anxiety, compared with Low Compensators. Such differences were not found when comparing individuals who had good versus poor ADOS scores, when ToM performance was good. Other core autistic characteristics (weak central coherence, nonsocial symptoms) did not differentiate the High and Low Compensators. CONCLUSIONS: IQ, EF and anxiety appear to be implicated in the processes by which certain autistic young people can compensate for their underlying ToM difficulties. This tendency to compensate does not appear to reflect the severity of 'hit' for ASD per se, suggesting that well-compensated individuals are not experiencing a milder form of ASD. The construct of compensation in ASD has implications for research and clinical practice. PMID- 29582426 TI - Prevalence of BRCA1/2 large genomic rearrangements in Chinese women with sporadic triple-negative or familial breast cancer. AB - The prevalence of BRCA1/2 large genomic rearrangements (LGRs) and their underlying mechanisms have not been fully evaluated in Chinese women with breast cancer. In this study, we determined the prevalence of BRCA1/2 LGRs in 834 patients with familial breast cancer (FBC) and 660 patients with sporadic triple negative breast cancer (TNBC) who were negative for BRCA1/2 small-range mutations using the multiplex ligation-dependent probe amplification method. We found that 20 index patients (2.4%) in the FBC group carried a BRCA1 or BRCA2 LGR, and the frequencies of BRCA1 and BRCA2 LGRs were 1.6% and 0.8%, respectively. Seven index patients (1.1%) carried a BRCA1 LGR in 660 sporadic TNBC patients, whereas no BRCA2 LGRs were found in these patients. Among the BRCA1/2 LGRs, 48.1% (13/27) were novel, and the breakpoints of the majority of the LGRs were identified. PsiBRCA1-mediated homologous recombination (HR) and Alu-mediated HR/non homologous end-joining (NHEJ) accounted for 40% and 30% of the BRCA1 LGRs, respectively. Alu-mediated HR accounted for 71.4% of the BRCA2 LGRs, and the remaining one-third was generated through Long interspersed nuclear elements (LINE)-mediated NHEJ. Our findings suggest that both FBC patients and sporadic TNBC patients should be tested for BRCA1/2 LGRs.

PMID- 29582429 TI - Early intervention (mobilization or active exercise) for critically ill adults in the intensive care unit. AB - BACKGROUND: Survivors of critical illness often experience a multitude of problems that begin in the intensive care unit (ICU) or present and continue after discharge. These can include muscle weakness, cognitive impairments, psychological difficulties, reduced physical function such as in activities of daily living (ADLs), and decreased quality of life. Early interventions such as mobilizations or active exercise, or both, may diminish the impact of the sequelae of critical illness. OBJECTIVES: To assess the effects of early intervention (mobilization or active exercise), commenced in the ICU, provided to critically ill adults either during or after the mechanical ventilation period, compared with delayed exercise or usual care, on improving physical function or performance, muscle strength and health-related quality of life. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase and CINAHL. We searched conference proceedings, reference lists of retrieved articles, databases of trial registries and contacted experts in the field on 31 August 2017. We did not impose restrictions on language or location of publications. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) or quasi-RCTs that compared early intervention (mobilization or active exercise, or both), delivered in the ICU, with delayed exercise or usual care delivered to critically ill adults either during or after the mechanical ventilation period in the ICU. DATA COLLECTION AND ANALYSIS: Two researchers independently screened titles and abstracts and assessed full-text articles against the inclusion criteria of this review. We resolved any disagreement through discussion with a third review author as required. We presented data descriptively using mean differences or medians, risk ratios and 95% confidence intervals. A meta-analysis was not possible due to the heterogeneity of the included studies. We assessed the quality of evidence with GRADE. MAIN RESULTS: We included four RCTs (a total of 690 participants), in this review. Participants were adults who were mechanically ventilated in a general, medical or surgical ICU, with mean or median age in the studies ranging from 56 to 62 years. Admitting diagnoses in three of the four studies were indicative of critical illness, while participants in the fourth study had undergone cardiac surgery. Three studies included range-of-motion exercises, bed mobility activities, transfers and ambulation. The fourth study involved only upper limb exercises. Included studies were at high risk of performance bias, as they were not blinded to participants and personnel, and two of four did not blind outcome assessors. Three of four studies reported only on those participants who completed the study, with high rates of dropout. The description of intervention type, dose, intensity and frequency in the standard care control group was poor in two of four studies.Three studies (a total of 454 participants) reported at least one measure of physical function. One study (104 participants) reported low-quality evidence of beneficial effects in the intervention group on return to independent functional status at hospital discharge (59% versus 35%, risk ratio (RR) 1.71, 95% confidence interval (CI) 1.11 to 2.64); the absolute effect is that 246 more people (95% CI 38 to 567) per 1000 would attain independent functional status when provided with early mobilization. The effects on physical functioning are uncertain for a range measures: Barthel Index scores (early mobilization: median 75 control: versus 55, low quality evidence), number of ADLs achieved at ICU (median of 3 versus 0, low quality evidence) or at hospital discharge (median of 6 versus 4, low quality evidence). The effects of early mobilization on physical function measured at ICU discharge are uncertain, as measured by the Acute Care Index of Function (ACIF) (early mobilization mean: 61.1 versus control: 55, mean difference (MD) 6.10, 95% CI -11.85 to 24.05, low quality evidence) and the Physical Function ICU Test (PFIT) score (5.6 versus 5.4, MD 0.20, 95% CI -0.98 to 1.38, low quality evidence). There is low quality evidence that early mobilization may have little or no effect on physical function measured by the Short Physical Performance Battery score at ICU discharge from one study of 184 participants (mean 1.6 in the intervention group versus 1.9 in usual care, MD -0.30, 95% CI -1.10 to 0.50), or at hospital discharge (MD 0, 95% CI -1.00 to 0.90). The fourth study, which examined postoperative cardiac surgery patients did not measure physical function as an outcome.Adverse effects were reported across the four studies but we could not combine the data. Our certainty in the risk of adverse events with either mobilization strategy is low due to the low rate of events. One study reported that in the intervention group one out of 49 participants (2%) experienced oxygen desaturation less than 80% and one of 49 (2%) had accidental dislodgement of the radial catheter. This study also found cessation of therapy due to participant instability occurred in 19 of 498 (4%) of the intervention sessions. In another study five of 101 (5%) participants in the intervention group and five of 109 (4.6%) participants in the control group had postoperative pulmonary complications deemed to be unrelated to intervention. A third study found one of 150 participants in the intervention group had an episode of asymptomatic bradycardia, but completed the exercise session. The fourth study reported no adverse events. AUTHORS' CONCLUSIONS: There is insufficient evidence on the effect of early mobilization of critically ill people in the ICU on physical function or performance, adverse events, muscle strength and health-related quality of life at this time. The four studies awaiting classification, and the three ongoing studies may alter the conclusions of the review once these results are available. We assessed that there is currently low-quality evidence for the effect of early mobilization of critically ill adults in the ICU due to small sample sizes, lack of blinding of participants and personnel, variation in the interventions and outcomes used to measure their effect and inadequate descriptions of the interventions delivered as usual care in the studies included in this Cochrane Review. PMID- 29582428 TI - Selective late sodium current inhibitor GS-458967 suppresses Torsades de Pointes by mostly affecting perpetuation but not initiation of the arrhythmia. AB - BACKGROUND AND PURPOSE: Enhanced late sodium current (late INa ) in heart failure and long QT syndrome type 3 is proarrhythmic. This study investigated the antiarrhythmic effect and mode of action of the selective and potent late INa inhibitor GS-458967 (GS967) against Torsades de Pointes arrhythmias (TdP) in the chronic atrioventricular block (CAVB) dog. EXPERIMENTAL APPROACH: Electrophysiological and antiarrhythmic effects of GS967 were evaluated in isolated canine ventricular cardiomyocytes and CAVB dogs with dofetilide-induced early afterdepolarizations (EADs) and TdP, respectively. Mapping of intramural cardiac electrical activity in vivo was conducted to study effects of GS967 on spatial dispersion of repolarization. KEY RESULTS: GS967 (IC50 ~200nM) significantly shortened repolarization in canine ventricular cardiomyocytes and sinus rhythm (SR) dogs, in a concentration and dose-dependent manner. In vitro, despite addition of 1MUM GS967, dofetilide-induced EADs remained present in 42% and 35% of cardiomyocytes from SR and CAVB dogs, respectively. Nonetheless, GS967 (787+/-265nM) completely abolished dofetilide-induced TdP in CAVB dogs (10/14 after dofetilide to 0/14 dogs after GS967), while single ectopic beats (sEB) persisted in 9 animals. In vivo mapping experiments showed that GS967 significantly reduced spatial dispersion of repolarization: cubic dispersion was significantly decreased from 237+/-54ms after dofetilide to 123+/-34ms after GS967. CONCLUSION AND IMPLICATIONS: GS967 terminated all dofetilide-induced TdP without completely suppressing EADs and sEB in vitro and in vivo, respectively. The antiarrhythmic mode of action of GS967, through the reduction of spatial dispersion of repolarization, seems to predominantly impede the perpetuation of arrhythmic events into TdP rather than their initiating trigger. PMID- 29582430 TI - Human periodontal ligament cells exhibit no endotoxin tolerance upon stimulation with Porphyromonas gingivalis lipopolysaccharide. AB - BACKGROUND/OBJECTIVES: Endotoxin tolerance is characterized by a state of hyporesponsiveness after confrontation with endotoxins such as lipopolysaccharides (LPS) at low concentrations. The aim of this study was to investigate, whether pretreatment with Porphyromonas gingivalis leads to endotoxin tolerance induction and possible alterations in toll-like receptor (TLR) 2- and 4-induced response in human periodontal ligament cells (hPDLCs). MATERIAL AND METHODS: Primary hPDLCs were pretreated with P. gingivalis (0.1 or 0.3 MUg/mL) LPS for 24 hours and afterwards treated with one of the following stimuli: P. gingivalis LPS (1 MUg/mL); TLR4 agonist Escherichia coli LPS (0.1 MUg/mL; 1 MUg/mL); TLR2 agonist Pam3CSK4 (0.1 MUg/mL; 1 MUg/mL). The protein expression of interleukin (IL)-6, IL-8 and monocyte chemotactic protein-1 was analyzed with quantitative polymerase chain reaction and enzyme-linked immunosorbent assay. Gene expression levels of TLR2 and TLR4 were determined by quantitative polymerase chain reaction. RESULTS: Pretreatment of cells with low concentrations of P. gingivalis LPS did not result in lower production of IL-6, IL-8 and monocyte chemotactic protein-1 compared to control group. In some cases, pretreated cells exhibited lower gene expression levels of TLR2 and TLR4 compared to non-pretreated cells. CONCLUSION: The results of this study implicate that hPDLCs do not develop endotoxin tolerance. Furthermore, the amplitude of the inflammatory response shows no significant dependency on TLR2 and TLR4 expression levels. PMID- 29582431 TI - Retinal histogenesis in an altricial avian species, the zebra finch (Taeniopygia guttata, Vieillot 1817). AB - Comparative developmental studies have shown that the retina of altricial fish and mammals is incompletely developed at birth, and that, during the first days of life, maturation proceeds rapidly. In contrast, precocial fish and mammals are born with fully differentiated retinas. Concerning birds, knowledge about retinal development is generally restricted to a single order of precocial birds, Galliformes, due to the fact that both the chicken and the Japanese quail are considered model systems. However, comparison of embryonic pre-hatchling retinal development between altricial and precocial birds has been poorly explored. The purpose of this study was to examine the morphogenesis and histogenesis of the retina in the altricial zebra finch (Taeniopygia guttata, Vieillot 1817) and compare the results with those from previous studies in the precocial chicken. Several maturational features (morphogenesis of the optic vesicle and optic cup, appearance of the first differentiated neurons, the period in which the non apical cell divisions are observable, and the emergence of the plexiform layers) were found to occur at later stages in the zebra finch than in the chicken. At hatching, the retina of T. guttata showed the typical cytoarchitecture of the mature tissue, although features of immaturity were still observable, such as a ganglion cell layer containing many thick cells, very thin plexiform layers, and poorly developed photoreceptors. Moreover, abundant mitotic activity was detected in the entire retina, even in the regions where the layering was complete. The circumferential marginal zone was very prominent and showed abundant mitotic activity. The partially undifferentiated stage of maturation at hatching makes the T. guttata retina an appropriate model with which to study avian postnatal retinal neurogenesis. PMID- 29582432 TI - Smoking, alcohol and cancer mortality in Eastern European men: Findings from the PrivMort retrospective cohort study. AB - Eastern European men have among the highest cancer mortality rates globally. Prevalence of smoking and alcohol intake in this region is also high. The aim of our study was to calculate population attributable risk fraction (PARF) of cancer deaths from smoking and alcohol in Russia, Belarus and Hungary, and to examine the contribution of these lifestyle factors to differences in male cancer mortality in the three countries. Data were collected as part of the PrivMort retrospective cohort study. Randomly selected participants living in mid-size towns in Russia, Belarus and Hungary provided information on smoking habits, alcohol consumption, vital status and cause of death (if applicable) of male relatives (fathers, siblings and partners). PARF of cancer deaths (age 35-79) due to smoking, alcohol consumption and both combined was estimated between 2001 and 2013. Among 72,190 men, 4,702 died of cancer. Age standardized cancer mortality rates were similar to official data in all three countries. The estimated PARF (95% CI) associated with measures of smoking, alcohol consumption, both combined, and overall smoking or drinking were 25% (19-30), 2% (0-4), 29% (19-39), 43% (32 53) in Russia, 18% (8-28), 2% (-1 to 6), 28% (20-35), 38% (25-50) in Belarus and 17% (13-20), 1% (0-3), 25% (20-30), 35% (28-42) in Hungary, respectively. These results suggest that in Eastern Europe, at least one third of cancer deaths in males may have been attributable to smoking and/or alcohol consumption in recent years. Health policies targeting these lifestyle factors can have a major impact on population health. PMID- 29582433 TI - Calcaneal adduction and eversion are coupled to talus and tibial rotation. AB - The purpose of this study was to quantify isolated coupling mechanisms of calcaneal adduction/abduction and calcaneal eversion/inversion to proximal bones in vitro. The in vitro approach is necessary because in vivo both movements appear together, making it impossible to determine the extent of their individual contribution to overall ankle joint coupling. Eight fresh frozen foot-leg specimens were tested. Data describing bone orientation and coupling mechanisms between segments were obtained using bone pin marker triads. The bone movement was described in a global coordinate system to examine the coupling between the calcaneus, talus and tibia. The strength of coupling was determined by means of the slope of a linear least squares fit to an angle-angle plot. The coupling coefficients in the present study indicate that not only calcaneal eversion/inversion (coupling coefficient: 0.68 +/- 0.15) but to an even greater extent calcaneal adduction/abduction (coupling coefficient: 0.99 +/- 0.10) was transferred into talus and tibial rotation, highlighting the relevance of calcaneal adduction for the overall ankle joint coupling. The results of this study present the possibility that controlling calcaneal adduction/abduction can affect talus and tibial rotation and therefore the possible genesis of overuse knee injuries. PMID- 29582434 TI - Latent class analysis of indicators of intolerance of uncertainty. AB - Intolerance of Uncertainty (IU) is a transdiagnostic vulnerability factor involved in depression and anxiety symptoms and disorders. IU encompasses Prospective IU ("Unforeseen events upset me greatly") and Inhibitory IU ("The smallest doubt can stop me from acting"). Research has yet to explore whether subgroups or classes of people exist characterized by different profiles of IU. This study used latent class analysis to identify such subgroups and examined if different classes of IU were distinct in terms of several cognitive vulnerabilities and psychological symptoms. Data were obtained from 519 students completing a 12-item measure of IU. Four subgroups were identified, characterized by low IU, predominantly Prospective IU, predominantly Inhibitory IU, and high IU, respectively. People in the high IU class reported cognitive vulnerabilities and depression and anxiety more than people in the low IU class. Inhibitory IU was more strongly associated with poor outcomes than was Prospective IU.

AB - The ultra long-acting beta2 -adrenoceptor agonist olodaterol plus the ultra long acting muscarinic antagonist tiotropium bromide are known to relax equine airways. In human bronchi combining these drugs elicits a positive interaction, thus we aimed to characterize this information further in equine isolated airways stimulated by electrical field stimulation (EFS) and using the Concentration Reduction Index (CRI) and Combination Index (CI) equations. The drugs were administered alone and together by reproducing ex vivo the concentration-ratio delivered by the currently available fixed-dose combination (1:1). The single agents elicited a significant (p < .05) concentration-dependent reduction in the EFS-induced contractility, that was synergistically improved (CI 0.18) when administered in combination (0.9 logarithms more potent, 24% more effective than the monocomponents). The drugs mixture allowed a reduction in the concentration of olodaterol from ?1 to ?2.3 logarithms. A favorable CRI was detected also for tiotropium bromide, whose concentration can be reduced ?1 logarithm at medium effect levels, remaining positive up to submaximal relaxant effect in the presence of olodaterol. The combination of tiotropium bromide/olodaterol allows the reduction in the concentration of the monocomponents to achieve airway smooth muscle relaxation, thus potentially decreases the risk of adverse events when these drugs are used to treat severe asthmatic horses. PMID- 29582436 TI - Modifiers of mesenchymal stem cell quantity and quality. AB - BACKGROUND: Clinical trials involving mesenchymal stem cell (MSC) therapy have variable outcomes. We hypothesize this is largely attributed to donor-to-donor variability and tissue of origin. STUDY DESIGN AND METHODS: We examined proliferation rates, cytokine secretion profiles, and differentiation capability of seven bone marrow-derived MSCs (BM-MSCs) and 16 adipose tissue-derived MSCs (AD-MSCs) from 23 donors. RESULTS: AD-MSCs had the capacity to undergo more than 40 population doublings, while the BM-MSC proliferation rate was found to be considerably slower. We observed more donor-to-donor variability in proliferation rates of BM-MSCs than with AD-MSCs. Cytokine analysis revealed that secretion of eight cytokines was significantly increased by AD-MSCs at Passage (P)3 compared with P1, while for BM-MSCs at P3 relative to P1, only interleukin-8 and RANTES secretion was significantly increased. By P5, secretion of all cytokines by AD MSCs was either decreased or unchanged relative to P1. In contrast, cytokine secretion by BM-MSCs at P5 was mostly unchanged, although secretion of six cytokines was significantly increased relative to P1. When we compared cytokine secretion between AD-MSCs and BM-MSCs at P3, AD-MSCs significantly secreted higher concentrations of cytokines than BM-MSCs while the opposite was observed at P5. This suggests that BM-MSCs are relatively more potent at P5 while AD-MSCs are relatively more potent at P3. AD-MSCs and BM-MSCs exhibited the capacity for chondrogenic differentiation. AD-MSCs and BM-MSCs appeared to display a more enhanced inclination toward adipogenic and osteogenic differentiation, respectively. CONCLUSION: MSC physiology is significantly influenced by donor variability and tissue of origin and this should be considered when designing clinical trials. PMID- 29582437 TI - Red blood cell transfusion after a global strategy for early detection and treatment of iron deficiency anemia: three-year results of a prospective observational study. AB - BACKGROUND: Anemia is the main indication for red blood cell (RBC) transfusion and iron deficiency is the most prevalent, preventable, and treatable cause of anemia worldwide. We aimed to assess the impact of iron deficiency anemia (IDA) on RBC transfusion by means of a program for prevention, early detection, and treatment. STUDY DESIGN AND METHODS: A prospective observational study was conducted starting in 2014 after an intervention in clinical practice in Melilla, a peripheral city isolated by 207 km sea distance to nearest continental Spain. Recommendations were proposed for first-step diagnosis of iron deficiency in the laboratory, oral iron prevention and treatment in primary care, and intravenous iron complexes and RBC transfusion for hospital management. Reduction in RBC use for years 2014 to 2016 was the primary outcome, with the period 2010 to 2013 considered as baseline performance for statistical analysis. RESULTS: Compared to baseline, there was a significant (p < 0.05) increase in mean (+/-SD) yearly reference population (79,748 +/- 3265 vs. 85,376 +/- 781), ferritin assays (6980 +/- 997 vs. 11,794 +/- 1567), admissions (6768 +/- 239 vs. 7629 +/- 191), and subjects exposed to iron therapy (3975 +/- 0.0 vs. 4667 +/- 21 for oral, 54 +/- 7 vs. 257 +/- 109 for sucrose, and 128 +/- 9 vs.176 +/- 15 for carboxymaltose iron). Mean yearly number of RBC units transfused decreased (1622 +/- 112 vs. 1434 +/- 44; p = 0.043), with a mean reduction of 11.6% from baseline, or 21.4% when estimated by units transfused per 1000 admissions. CONCLUSIONS: Management of IDA is a target to avoid RBC transfusion, and awareness of this health problem should be among the first pillars for any patient blood management program. PMID- 29582438 TI - A pilot serosurvey of Babesia microti in Chinese blood donors. AB - BACKGROUND AND OBJECTIVES: Babesia spp. are tick-borne, intraerythrocytic protozoan parasites, several of which are transfusion-transmissible. Transfusion transmitted babesiosis poses serious risk to a diverse patient population, including neonates, patients aged >50 years, the asplenic and the immunocompromised that are over-represented among transfusion recipients. Despite reports of B. microti and B. venatorum in People's Republic of China (PRC), no surveillance of blood donors for Babesia has previously been undertaken. We sought to determine the rates of B. microti seroreactivity in a sample of blood donors in the PRC. MATERIALS AND METHODS: A pilot serosurvey was conducted of community blood donors (n = 1000) who donated July-August 2016 at Mudanjiang Blood Center (Heilongjiang Province) using indirect fluorescent antibody testing for antibodies against B. microti. The slides were prepared using B. microti infected hamster blood. Samples that were initially positive to a titre of 64 were subjected to repeat IFA testing. Final seroreactivity was based on repeat reactivity to >=64. RESULTS: A total of 1000 individual donor samples were evaluated, comprising 888 whole blood and 112 platelet donations. Thirteen of 1000 (1.3%) donors were seroreactive for B. microti [8 (0.8%) and five (0.05%) at titres of 64 and 128, respectively]. CONCLUSION: Our preliminary findings support the need for expanded Babesia surveillance in Chinese blood donors, replete with molecular evaluation, to evaluate the risk to the blood supply. PMID- 29582439 TI - Radiation dose dependence on subject size in abdominal computed tomography: Water phantom and patient model comparison. AB - PURPOSE: Development of patient organ dose evaluation method in computed tomography (CT) needs to model the correlation between organ dose and patient size, under various conditions of scan length, tube current lineshape, and organ location. To facilitate this task, this work was to perform a comprehensive study of the relationship between the dose to water phantom and its diameter under various settings of phantom axis, scan length, and the location across or beyond the scanned range. METHODS: A dose calculation algorithm and the published data by Li et al. [Med. Phys. 39, 5347-5352 (2012); 40, 031903 (2013); 43, 5878-5888 (2016)] were used to calculate longitudinal dose distribution DL (z) in 10- to 50 cm diameter water phantoms undergoing constant tube current scans. The relationship between dose and phantom diameter was examined on three phantom axes (center, cross-sectional average, periphery), at seven scan lengths from 15 to 70 cm, and at eight longitudinal locations within or beyond each scan range. The water phantom results were compared to those of patient models of eight previous studies. RESULTS: For the water phantoms matching the abdominal perimeters (36.3 124.5 cm) of the GSF family of voxelized phantoms, the median and range of DL (z)(water) across scan range were consistent with those of the organ doses from the GSF phantom abdominal scans of a previous study. In 41 water phantoms (diameters 10-50 cm), DL (z)(water) at locations inside scan range decreased with increasing phantom diameters. Exponential regression analysis of the above trend yielded regression parameters approximately consistent with those of phantom or patient models of eight previous studies. However, the usual exponential function might not be optimal for modeling the dose dependence on subject size. Inside scan range, the log(dose) vs diameter curve was non-linear on a semilogarithmic graph. Outside of scan range, dose might increase with larger subject sizes, contradicting to the exponential attenuation law. In the CT examinations of a patient population, direct modeling of organ dose dependence on patient size would be more challenging due to varying scan lengths and changing organ distances to the scan range centers. CONCLUSION: An efficient approach to take into account the abdominal organ dose dependences on other factors is to calculate DL (z)(water) with the water equivalent diameter, scan length, and tube current lineshape from the patient examinations, and to evaluate the organ dose to DL (z)(water) ratio, where z is at the organ's longitudinal location. The ratio may be used for abdominal organ dose evaluation in the patient examinations. How to make use of DL (z)(water) for organ dose evaluation in other body regions may be explored in the future. PMID- 29582440 TI - A preclinical Talbot-Lau prototype for x-ray dark-field imaging of human-sized objects. AB - PURPOSE: Talbot-Lau x-ray interferometry provides information about the scattering and refractive properties of an object - in addition to the object's attenuation features. Until recently, this method was ineligible for imaging human-sized objects as it is challenging to adapt Talbot-Lau interferometers (TLIs) to the relevant x-ray energy ranges. In this work, we present a preclinical Talbot-Lau prototype capable of imaging human-sized objects with proper image quality at clinically acceptable dose levels. METHODS: The TLI is designed to match a setup of clinical relevance as closely as possible. The system provides a scan range of 120 * 30 cm2 by using a scanning beam geometry. Its ultimate load is 100 kg. High aspect ratios and fine grid periods of the gratings ensure a reasonable setup length and clinically relevant image quality. The system is installed in a university hospital and is, therefore, exposed to the external influences of a clinical environment. To demonstrate the system's capabilities, a full-body scan of a euthanized pig was performed. In addition, freshly excised porcine lungs with an extrinsically provoked pneumothorax were mounted into a human thorax phantom and examined with the prototype. RESULTS: Both examination sequences resulted in clinically relevant image quality - even in the case of a skin entrance air kerma of only 0.3 mGy which is in the range of human thoracic imaging. The presented case of a pneumothorax and a reader study showed that the prototype's dark-field images provide added value for pulmonary diagnosis. CONCLUSION: We demonstrated that a dedicated design of a Talbot-Lau interferometer can be applied to medical imaging by constructing a preclinical Talbot-Lau prototype. We experienced that the system is feasible for imaging human-sized objects and the phase-stepping approach is suitable for clinical practice. Hence, we conclude that Talbot-Lau x-ray imaging has potential for clinical use and enhances the diagnostic power of medical x-ray imaging. PMID- 29582441 TI - D-immunized blood donors who are female and who possess at least one HLA-DRB1*15 allele show a propensity for high serum RhIG production. AB - BACKGROUND: D- individuals with previous D-incompatible pregnancies and/or blood transfusions, as well as those who are actively immunized with small-volume D+ red blood cells (RBCs), are stimulated to produce RhIG. Many factors could influence the stimulation of immunoglobulin production in response to foreign antigen (such as antigen immunogenicity and genetic factors), and it is unknown whether genetic markers could potentially identify responder anti-D donors. STUDY DESIGN AND METHODS: Anti-D donors were assigned a responder profile based on their serum RhIG levels (n = 431). A subset of donors (n = 272) had DNA extracted for polymerase chain reaction genotyping assays for target genes in antigen presentation and pathogen recognition receptors (TLR2, TLR4, CD14, FcgammaRIIA, and the MHC Class II locus HLA-DRB1). Statistical tests for associations between anti-D donor responder profiles and genetic factors were performed. RESULTS: A large proportion of our donors (38.7%) were classified as nonresponder donors, despite receiving multiple D+ RBC immunizations, whereas female sex was significantly associated with an all-responder profile (p < 0.001). The presence of the DRB1*15 allele and absence of the DRB1*04 allele were more likely to be associated with a responder anti-D donor, although not significantly after Bonferroni correction. A combination of the DRB1*15 allele and female sex was significantly associated with an anti-D donor responder profile. CONCLUSION: This study has identified female sex and the HLA-DRB1*15 allele as potentially useful markers that could be used to screen donors before entry into D immunization programs. PMID- 29582442 TI - Relationship between fetal peak systolic velocity in Middle cerebral artery and umbilical blood gas values and hemoglobin levels in diabetic pregnant women. AB - PURPOSE: To assess the relationship between peak systolic velocity in the middle cerebral artery (MCA-PSV) and fetal hypoxia in diabetic pregnant women requiring insulin therapy. METHODS: The data of diabetic pregnant women using insulin who were followed in our departments were reviewed retrospectively. The relationships between MCA-PSV and umbilical cord pO2, pCO2, base deficit, hemoglobin, and birth weight were analyzed. RESULTS: A total of 120 cases were included in the final analysis. The median (Q1 - Q3 ) gestational age at Doppler evaluation was 37 weeks 3 days (37-38 weeks and 2 days), and the mean +/- SD gestational age at delivery was 38 weeks 4 days +/- 3days. The mean +/- SD hemoglobin A1c (HbA1c) level was 5.7% +/- 1.0% and, median (Q1 -Q3 ) daily total insulin dose was 25 U (10U-48U). There was no statistically significant correlation between MCA-PSV and pH, PO2, PCO2, base deficit, Hb, and birth weight (Spearman correlation, r: .001[P = .99], r:-.011[P = .90], r:-.052 [P = .51], r: .049[P = .59], r: .049 [P = .59], r: .030 [P = .75], respectively). Using binary logistic regression analysis, no independent factor for the prediction of fetal acidosis (venous pH < 7.23), and metabolic acidosis (base deficit >6.3 mmol/L) was detected. CONCLUSION: MCA-PSV is not a good indicator of fetal polycythemia or chronic hypoxia in fetuses of diabetic pregnant women. Fetal well-being should be monitored with other tools in these circumstances. PMID- 29582443 TI - Jealousy at work: The role of rivals' characteristics. AB - The present study examined rival characteristics that may evoke jealousy in the workplace, differences between men and women in this regard, and the relationship between jealousy responses and intrasexual competitiveness and social comparison orientation. Participants were 426 male and female employees. By means of a questionnaire, participants were presented with a jealousy-evoking scenario after which jealousy responses to 24 rival characteristics were assessed. Findings showed that a rival's social communal attributes evoked highest levels of jealousy, and that, compared to men, women reported more jealousy in response to a rival's physical attractiveness. Overall, as individuals had higher scores on intrasexual competitiveness and social comparison orientation, they also experienced more jealousy in response to their rival, regardless of his or her characteristics. These findings suggest that those characteristics that are highly valued in employees may backfire when employees perceive co-workers as rivals. PMID- 29582444 TI - 'You must know what you mean when you say that': the morality of knowledge claims about ADHD in radio phone-ins. AB - Drawing on a corpus of radio phone-ins, we present a discursive psychological analysis of how mothers carefully tailor their knowledge claims regarding their children with Attention Deficit Hyperactivity Disorder (ADHD). Mothers typically claim knowledge about their children's good intentions, but not about the 'ADHD ness' of their conduct. Whereas the former is seen as appropriate knowledge for a concerned parent, the latter is treated as a matter of expert knowledge. We show that as soon as problematic behaviour is treated as observable from the outside and describable by mothers and other lay persons, it becomes vulnerable to being formulated as 'normal disobedience', rather than symptomatic of a professionally administered, doctorable condition. We argue that it is important to be aware of the moralities hidden in knowledge claims, as they help sustain an unproductive perspective in which either the child's brain or his mother is blamed for behaviour perceived as problematic. PMID- 29582445 TI - Development of new extraction method based on liquid-liquid-liquid extraction followed by dispersive liquid-liquid microextraction for extraction of three tricyclic antidepressants in plasma samples. AB - In the present study, a new extraction method based on a three-phase system, liquid-liquid-liquid extraction, followed by dispersive liquid-liquid microextraction has been developed and validated for the extraction and preconcentration of three commonly prescribed tricyclic antidepressant drugs - amitriptyline, imipramine, and clomipramine - in human plasma prior to their analysis by gas chromatography-flame ionization detection. The three phases were an aqueous phase (plasma), acetonitrile and n-hexane. The extraction mechanism was based on the different affinities of components of the biological sample (lipids, fatty acids, pharmaceuticals, inorganic ions, etc.) toward each of the phases. This provided high selectivity toward the analytes since most interferences were transferred into n-hexane. In this procedure, a homogeneous solution of the aqueous phase (plasma) and acetonitrile (water-soluble extraction solvent) was broken by adding sodium sulfate (as a phase separating agent) and the analytes were extracted into the fine droplets of the formed acetonitrile. Next, acetonitrile phase was mixed with 1,2-dibromoethane (as a preconcentration solvent at microliter level) and then the microextraction procedure mentioned above was performed for further enrichment of the analytes. Under the optimum extraction conditions, limits of detection and lower limits of quantification for the analytes were obtained in the ranges of 0.001-0.003 and 0.003-0.010 MUg mL-1 , respectively. The obtained extraction recoveries were in the range of 79-98%. Intra- and inter-day precisions were < 7.5%. The validated method was successfully applied for determination of the selected drugs in human plasma samples obtained from the patients who received them. PMID- 29582446 TI - Molecular genetic studies in a case series of isolated hypoaldosteronism due to biosynthesis defects or aldosterone resistance. AB - BACKGROUND AND AIM: Hypoaldosteronism is associated with either insufficient aldosterone production or aldosterone resistance (pseudohypoaldosteronism). Patients with aldosterone defects typically present with similar symptoms and findings, which include failure to thrive, vomiting, hyponatremia, hyperkalemia and metabolic acidosis. Accurate diagnosis of these clinical conditions therefore can be challenging. Molecular genetic analyses can help to greatly clarify this complexity. The aim of this study was to obtain an overview of the clinical and genetic characteristics of patients with aldosterone defects due to biosynthesis defects or aldosterone resistance. DESIGN AND PATIENTS: We investigated the clinical and molecular genetic features of 8 consecutive patients with a clinical picture of aldosterone defects seen in our clinics during the period of May 2015 through October 2017. We screened CYP11B2 for aldosterone synthesis defects and NR3C2 and the three EnaC subunits (SCNN1A, SCNN1B and SCNN1G) for aldosterone resistance. RESULTS: We found 4 novel and 2 previously reported mutations in the genes CYP11B2, NR3C2, SCNN1A and SCNN1G in 9 affected individuals from 7 unrelated families. CONCLUSION: Molecular genetic investigations can help confidently diagnose these conditions and clarify the pathogenicity of aldosterone defects. This study may expand the clinical and genetic correlations of defects in aldosterone synthesis or resistance. PMID- 29582448 TI - Generalized lymphatic anomaly successfully treated with long-term, low-dose sirolimus. AB - Generalized lymphatic anomaly is a rare, complex, lymphatic anomaly generally involving soft tissues, spleen, and bones. It can lead to focal skeletal fragility and pathologic effusions. A recent prospective trial of sirolimus for complicated vascular anomalies showed partial response in seven patients with generalized lymphatic anomaly treated with sirolimus with a target trough level of 10-15 ng/mL for 1 year (Adams et al). We describe successful treatment of generalized lymphatic anomaly with a lower-dose, long-term course of sirolimus. PMID- 29582447 TI - Sleep study-guided multidisciplinary therapy (SGMT) for patients with acute coronary syndrome: Trial rationale and design. AB - Obstructive sleep apnea (OSA) is an emerging risk marker for acute coronary syndrome (ACS). This randomized trial aims to determine the effects of sleep study-guided multidisciplinary therapy (SGMT) comprising overnight sleep study, continuous positive airway pressure, and behavioral therapy for OSA during the subacute phase of ACS. We hypothesize that SGMT will reduce (1) the plasma levels of N-terminal pro brain natriuretic peptide and suppression of tumorigenicity 2; (2) the estimated 10-year risk of cardiovascular mortality as measured by the European Systematic Coronary Risk Evaluation (SCORE) algorithm; and (3) the cardiovascular event rate during a 3-year follow-up, compared with standard therapy. In the SGMT trial, 180 patients presenting with ACS will be randomly assigned to SGMT (n = 90) and standard therapy (n = 90) groups. Both groups will receive guideline-mandated treatment for ACS. Those assigned to SGMT will additionally undergo a sleep study and, if OSA is diagnosed, attend a multidisciplinary OSA clinic where they will receive personalized treatment including continuous positive airway pressure and behavioral/lifestyle counseling. The primary endpoint is the plasma N-terminal pro brain natriuretic peptide concentration at 7-month follow-up. This report presents the baseline characteristics of 117 patients (SGMT group: n =54; standard therapy group: n =63) who had been enrolled into the study as of August 31, 2017. The results of this trial will help us to understand whether active OSA diagnosis and treatment will improve the physiologic and clinical cardiovascular outcomes of this group of patients. PMID- 29582449 TI - The hOGG1 Ser326Cys polymorphism and male subfertility in Taiwanese patients with varicocele. AB - To investigate the association between the human 8-oxoguanine DNA glycosylase 1 (hOGG1) gene Ser326Cys polymorphism and male subfertility in Taiwanese patients with varicocele, we made a prospective study. Ninety young male patients with varicocele (group 1), 50 young male patients with subclinical varicocele (group 2) and 30 normal young male patients without varicocele (group 3) were recruited in this study. The hOGG1 null homozygous genotype (Cys/Cys) and the occurrence of a 4,977-bp deletion in mitochondrial DNA and mitochondrial copy number in spermatozoa were determined by polymerase chain reaction. The 8-hydroxy-2' deoxyguanosine (8-OHdG) content of DNA in the spermatozoa was measured using high performance liquid chromatography, and total antioxidant capacity (TAC) of seminal plasma was detected electrochemically. The rates of male subfertility were 31.1% (28/90) in group 1 and 22% (11/50) in group 2. Of 39 subfertile men, 74.4% (29/39) had the hOGG1 Cys/Cys genotype. Patients in groups 1 and 2 with hOGG1 Cys/Cys genotype had significantly higher 8-OHdG content in sperm DNA, lower mitochondrial copy number in spermatozoa and lower TAC in seminal plasma than those with Ser/Ser or Ser/Cys genotype. Clinicians should pay more attention to patients with varicocele with the hOGG1 Cys/Cys genotype. PMID- 29582450 TI - Tamper-resistant prescription forms for narcotics in France: Should we generalize them? AB - In France, prescription of narcotics must be written on a tamper-resistant prescription form with specific technical particularities. Dosage and daily dose of medicines shall be written out entirely in letters. These prescription forms are also mandatory for buprenorphine, clorazepate, clonazepam, tianeptine, buccal midazolam and zolpidem owing to traffic, abuse or diversion. In 2012, to assess the use of standard and tamper-resistant prescription forms and the acceptability of the generalization of the latter to all medicines, a national opinion survey was performed, with a postal questionnaire, within three randomized samples of 1500 prescribers (physicians, dentists and midwives). Of the 403 participating prescribers (participation rate of 26.8%), 373 were physicians, 14 dentists and 16 midwives. Tamper-resistant prescription forms were used by 76.2% of prescribers, but only by 5.1% in a computerized version, whereas for standard prescription forms, 61% used computer assisted prescription software. The main reason was the inability of the prescription software to print these forms or to respect the mandatory prescription rules for narcotics. Theft and falsification of prescriptions had ever occurred (working life). Most prescribers (62.5%) were against the generalization of tamper-resistant prescription forms. Those in favour were for a generalization to all medicines (65%) and not only to psychotropic agents. Generalization of tamper-resistant prescription forms is not a consensual solution to prevent medicines' diversion. Some prescribers alluded to the possibility of dematerialization and electronic transmission of prescription forms, which could avoid theft, forgery or falsification.

Successful treatment with topical N-acetylcysteine has been reported in a small number of patients, with generally good results. We report the finding of a retrospective chart review of 18 patients treated with N-acetylcysteine. Although topical N-acetylcysteine is an effective therapy for some patients with ichthyosis, problems with irritation, objectionable odor, and compounding costs limit its use. PMID- 29582452 TI - Design of cancer trials based on progression-free survival with intermittent assessment. AB - Therapeutic advances in cancer mean that it is now impractical to performed phase III randomized trials evaluating experimental treatments on the basis of overall survival. As a result, the composite endpoint of progression-free survival has been routinely adopted in recent years as it is viewed as enabling a more timely and cost-effective approach to assessing the clinical benefit of novel interventions. This article considers design of cancer trials directed at the evaluation of treatment effects on progression-free survival. In particular, we derive sample size criteria based on an illness-death model that considers cancer progression and death jointly while accounting for the fact that progression is assessed only intermittently. An alternative approach to design is also considered in which the sample size is derived based on a misspecified Cox model, which uses the documented time of progression as the progression time rather than dealing with the interval censoring. Simulation studies show the validity of the proposed methods. PMID- 29582453 TI - Bayesian modelling of lung function data from multiple-breath washout tests. AB - Paediatric respiratory researchers have widely adopted the multiple-breath washout (MBW) test because it allows assessment of lung function in unsedated infants and is well suited to longitudinal studies of lung development and disease. However, a substantial proportion of MBW tests in infants fail current acceptability criteria. We hypothesised that a model-based approach to analysing the data, in place of traditional simple empirical summaries, would enable more efficient use of these tests. We therefore developed a novel statistical model for infant MBW data and applied it to 1197 tests from 432 individuals from a large birth cohort study. We focus on Bayesian estimation of the lung clearance index, the most commonly used summary of lung function from MBW tests. Our results show that the model provides an excellent fit to the data and shed further light on statistical properties of the standard empirical approach. Furthermore, the modelling approach enables the lung clearance index to be estimated by using tests with different degrees of completeness, something not possible with the standard approach. Our model therefore allows previously unused data to be used rather than discarded, as well as routine use of shorter tests without significant loss of precision. Beyond our specific application, our work illustrates a number of important aspects of Bayesian modelling in practice, such as the importance of hierarchical specifications to account for repeated measurements and the value of model checking via posterior predictive distributions. PMID- 29582454 TI - Fine structure of the canal neuromasts of the lateral line system in the adult zebrafish. AB - The mechanosensory lateral line system of fish is responsible for several functions such as balance, hearing, and orientation in water flow and is formed by neuromast receptor organs distributed on head, trunk and tail. Superficial and canal neuromasts can be distinguished for localization and morphological differences. Several information is present regarding the superficial neuromasts of zebrafish and other teleosts especially during larval and juvenile stages, while not as numerous data are so far available about the ultrastructural characteristics of the canal neuromasts in adult zebrafish. Therefore, the aim of this study was to investigate by transmission electron microscopy the ultrastructural aspects of cells present in the canal neuromasts. Besides the typical cellular aspects of the neuromast, different cellular types of hair cells were observed that could be identified as developing hair cells during the physiological turnover. The knowledge of the observed cellular types of the canal neuromasts and their origin could give a contribution to studies carried out on adult zebrafish used as model in neurological and non-neurological damages, such as deafness and vestibular disorders. PMID- 29582455 TI - Pediatric Old World cutaneous leishmaniasis treated with oral fluconazole: A case series. AB - BACKGROUND: Cutaneous leishmaniasis has an incidence of 0.7-1.2 million cases per year and represents a growing concern in the outpatient dermatologic practice in Europe because of imported cases due to increased travel to risk areas and to immigration phenomena. When dealing with children, the treatment can be challenging because of side effects and pain of classic antimonial therapy leading to poor rates of course completion and requirement of sedation for several children. METHODS: We retrospectively studied three cases of cutaneous leishmaniasis in pediatric patients, between the ages of 3 and 6 years of age, treated with oral fluconazole. We examined the efficacy, the tolerability, the safety profile and the cosmetic result of fluconazole at a dose of 6 mg/kg/daily for 6 weeks. RESULTS: The patients had a complete resolution of their lesions with minimal scarring. No adverse effect was reported. The leishmaniasis species identified were L. major or L. tropica. CONCLUSION: Considering sides effects and the parents' and the clinician's concern for systemic treatment in the pediatric population, fluconazole represents a valid, safe and easily manageable option for Old World cutaneous leishmaniasis in pediatric outpatients caused by L. major or L. tropica.

AB - PURPOSE: Spin-lattice relaxation rate (R1 )-based time-domain EPR oximetry is reported for in vivo applications using a paramagnetic probe, a trityl-based Oxo71. METHODS: The R1 dependence of the trityl probe Oxo71 on partial oxygen pressure (pO2 ) was assessed using single-point imaging mode of spatial encoding combined with rapid repetition, similar to T1 -weighted MRI, for which R1 was determined from 22 repetition times ranging from 2.1 to 40.0 MUs at 300 MHz. The pO2 maps of a phantom with 3 tubes containing 2 mM Oxo71 solutions equilibrated at 0%, 2%, and 5% oxygen were determined by R1 and apparent spin-spin relaxation rate ( R2*) simultaneously. RESULTS: The pO2 maps derived from R1 and R2* agreed with the known pO2 levels in the tubes of Oxo71. However, the histograms of pO2 revealed that R1 offers better pO2 resolution than R2* in low pO2 regions. The SDs of pixels at 2% pO2 (15.2 mmHg) were about 5 times lower in R1 -based estimation than R2*-based estimation (mean +/- SD: 13.9 +/- 1.77 mmHg and 18.3 +/ 8.70 mmHg, respectively). The in vivo pO2 map obtained from R1 -based assessment displayed a homogeneous profile in low pO2 regions in tumor xenografts, consistent with previous reports on R2*-based oximetric imaging. The scan time to obtain the R1 map can be significantly reduced using 3 repetition times ranging from 4.0 to 12.0 MUs. CONCLUSION: Using the single-point imaging modality, R1 based oximetry imaging with useful spatial and oxygen resolutions for small animals was demonstrated.

AB - Angiomatoid and desmoplastic Spitz nevi are rare histologic variants of Spitz nevi that present most frequently on the extremities of children and young adults. Although Spitz nevi are clinically heterogeneous, one presenting as a keloidal nodule has not been previously published. We present a case of an angiomatoid and desmoplastic Spitz nevus clinically akin to a keloid on an African-American teenager and describe its unique histopathologic features. PMID- 29582460 TI - Rutaecarpine attenuates osteoclastogenesis by impairing macrophage colony stimulating factor and receptor activator of nuclear factor kappa-B ligand stimulated signalling pathways. AB - Rutaecarpine is a major alkaloid isolated from Evodia rutaecarpa. Here, we investigated the effects of rutaecarpine on osteoclast differentiation induced by macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor kappa-B ligand (RANKL) in bone marrow-derived macrophages (BMMs). Treatment with rutaecarpine significantly inhibited osteoclastogenesis and prevented bone resorption of BMM-derived osteoclasts. Mechanistically, rutaecarpine decreased the protein level of nuclear factor of activated T cells cytoplasmic-1 (NFATc1) and the phosphorylation of other signalling pathways during the osteoclast differentiation. Thus, rutaecarpine may be useful as a therapeutic agent for the treatment of bone diseases. PMID- 29582461 TI - Short anagen syndrome: Case series and literature review. AB - BACKGROUND/OBJECTIVES: Short anagen syndrome is a hair cycle disorder usually diagnosed in early childhood and characterized by short hair length due to short duration of the anagen phase. The objective was to review the presentation and demographic characteristics of short anagen syndrome and compare them with the most common differential diagnosis, loose anagen syndrome. METHODS: A retrospective review of eight children with short anagen syndrome was performed at the University of Miami Outpatient Dermatology Clinic. RESULTS: The diagnosis of short anagen syndrome was confirmed according to clinical findings and characteristic short telogen hairs with pointed tips on the hair pull test. CONCLUSION: This is the largest reported clinical series of short anagen syndrome thus far in the literature. PMID- 29582462 TI - Omeprazole-induced hypertrichosis in two children. AB - Omeprazole significantly increases duodenal prostaglandin E2 synthesis. Prostaglandins are involved in hair growth regulation: prostaglandin E2 and prostaglandin F2 alpha stimulate hair growth, and prostaglandin D2 has an inhibitory effect. The use of omeprazole can cause acquired generalized hypertrichosis by increasing prostaglandin E2 levels. PMID- 29582463 TI - Software tools and tutorials in liquid state NMR. PMID- 29582465 TI - Tularemia-induced erythema multiforme minor in an 11-year-old girl. AB - Tularemia is a rare and potentially life-threatening infection caused by the highly infectious gram-negative coccobacillus Francisella tularensis. We present the case of an 11-year old girl who presented with erythema multiforme minor in the setting of an indolent but progressive soft tissue infection and was found to have tularemia. We review the role of dermatologists in identifying the features of and complications associated with this rare zoonosis and discuss the potential effect of climate change on its incidence. PMID- 29582464 TI - Super-resolution musculoskeletal MRI using deep learning. AB - PURPOSE: To develop a super-resolution technique using convolutional neural networks for generating thin-slice knee MR images from thicker input slices, and compare this method with alternative through-plane interpolation methods. METHODS: We implemented a 3D convolutional neural network entitled DeepResolve to learn residual-based transformations between high-resolution thin-slice images and lower-resolution thick-slice images at the same center locations. DeepResolve was trained using 124 double echo in steady-state (DESS) data sets with 0.7-mm slice thickness and tested on 17 patients. Ground-truth images were compared with DeepResolve, clinically used tricubic interpolation, and Fourier interpolation methods, along with state-of-the-art single-image sparse-coding super-resolution. Comparisons were performed using structural similarity, peak SNR, and RMS error image quality metrics for a multitude of thin-slice downsampling factors. Two musculoskeletal radiologists ranked the 3 data sets and reviewed the diagnostic quality of the DeepResolve, tricubic interpolation, and ground-truth images for sharpness, contrast, artifacts, SNR, and overall diagnostic quality. Mann-Whitney U tests evaluated differences among the quantitative image metrics, reader scores, and rankings. Cohen's Kappa (kappa) evaluated interreader reliability. RESULTS: DeepResolve had significantly better structural similarity, peak SNR, and RMS error than tricubic interpolation, Fourier interpolation, and sparse coding super-resolution for all downsampling factors (p < .05, except 4 * and 8 * sparse-coding super-resolution downsampling factors). In the reader study, DeepResolve significantly outperformed (p < .01) tricubic interpolation in all image quality categories and overall image ranking. Both readers had substantial scoring agreement (kappa = 0.73). CONCLUSION: DeepResolve was capable of resolving high-resolution thin-slice knee MRI from lower-resolution thicker slices, achieving superior quantitative and qualitative diagnostic performance to both conventionally used and state-of-the-art methods. PMID- 29582466 TI - Unique cell tropism of HHV-6B in an infantile autopsy case of primary HHV-6B encephalitis. AB - Human herpes virus 6 (HHV-6) is known to cause primary encephalitis in the frontal lobes/cerebral hemisphere or reactivated encephalitis in the hippocampus, but the pathogenesis remains unclear. HHV-6B has also been detected in hippocampal samples in patients with mesial temporal lobe epilepsy. A 1 year and 3 months old female, who had been clinically diagnosed with exanthema subitum and febrile convulsion, was found dead on the third day after onset. Macroscopic findings showed massive brain edema. Microscopic examination revealed gemistocytic astrocytes and ballooned oligodendrocytes in the frontal white matter, along with neuronal cell death with microglial infiltration in the frontal cortex. Polymerase chain reaction detected HHV-6B in the cerebrospinal fluid and necropsy brain samples. The hippocampus showed a 4-5-fold increase in virus copy number of HHV-6B compared to samples from other brain sites. Immunostaining indicated that HHV-6B had infected vascular endothelial cells, neurons and oligodendrocytes but not astrocytes or microglia. Hippocampal neurons were infected with highly concentrated HHV-6B, but the hippocampus had neither neuronal loss nor reactive glial response. Silent and abundant HHV-6B infection in the hippocampus might be associated with latent infection, reactivation and some hippocampus-oriented disorders, including mesial temporal lobe epilepsy. PMID- 29582467 TI - Recent Progress in Organic Electrodes for Li and Na Rechargeable Batteries. AB - Organic rechargeable batteries, which use organics as electrodes, are excellent candidates for next-generation energy storage systems because they offer design flexibility due to the rich chemistry of organics while being eco-friendly and potentially cost efficient. However, their widespread usage is limited by intrinsic problems such as poor electronic conductivity, easy dissolution into liquid electrolytes, and low volumetric energy density. New types of organic electrode materials with various redox centers or molecular structures have been developed over the past few decades. Moreover, research aimed at enhancing electrochemical properties via chemical tuning has been at the forefront of organic rechargeable batteries research in recent years, leading to significant progress in their performance. Here, an overview of the current developments of organic rechargeable batteries is presented, with a brief history of research in this field. Various strategies for improving organic electrode materials are discussed with respect to tuning intrinsic properties of organics using molecular modification and optimizing their properties at the electrode level. A comprehensive understanding of the progress in organic electrode materials is provided along with the fundamental science governing their performance in rechargeable batteries thus a guide is presented to the optimal design strategies to improve the electrochemical performance for next-generation battery systems. PMID- 29582468 TI - Let-7c restores radiosensitivity and chemosensitivity and impairs stemness in oral cancer cells through inhibiting interleukin-8. AB - BACKGROUND: The let-7 family of microRNAs has been considered as tumor suppressors in various cancers; however, the role of let-7c in oral squamous cell carcinoma has not been determined yet. METHODS: In this study, phenotypical behaviors and the radio/chemoresistance were examined subsequent to overexpression of let-7c. In addition, the expression of let-7c in cancer stem cells (CSCs) was evaluated and the effect of let-7c on stemness characteristics was assessed. Also, luciferase activity assays were performed to test whether interleukin (IL)-8 was a putative target of let-7c. RESULTS: Our results confirmed that the expression of let-7c in CSCs was reduced, while overexpression of let-7c attenuated the oncogenicity. Moreover, ectopic expression of let-7c in CSCs downregulated the stemness hallmarks and the radio/chemoresistance. Expression and secretion of IL-8 in oral CSCs were both reduced following overexpression of let-7c. Besides, the inhibitory effect of let-7c on various stemness phenotypes was reverted by IL-8, indicating that lower expression of let 7c may confer higher cancer stemness through a failure to downregulate IL-8. CONCLUSION: These findings revealed the significance of let-7c in the contribution of oral cancer stemness and radio/chemoresistance. Targeting let-7c and its downstream IL-8 may be beneficial to prevent cancer recurrence and metastasis of oral squamous cell carcinoma. PMID- 29582469 TI - No evidence for follicular keratinocyte hyperproliferation in acne lesions as compared to autologous healthy hair follicles. AB - Abnormal hyperkeratinization in sebaceous hair follicles has long been believed to play an important role in acne pathogenesis. Several early reports purported to provide histological evidence for hyperproliferation of keratinocytes in acne lesions by showing a higher expression of the Ki67 as well as certain keratins. The evidence is, however, not robust, and a number of methodological and technical limitations can be identified in these studies. In this study, we looked at the expression of proliferation, mitosis and apoptosis markers directly at acne skin lesions in 66 patients with acne vulgaris. Ki67 was assessed using immunohistochemistry and alpha-tubulin, phospho-histone H3 and cleaved-PARP with immunofluorescence microscopy. Allogenic unaffected hair follicles from the same acne patients were used as an internal control. In both acne and control hair follicles, the alpha-tubulin staining was universal, approaching 100% cells and showed no signs of changed assembly. Expression of cleaved-PARP-the apoptosis marker-was a rare event. Cell proliferation rate measured by the expression of Ki67 and phospho-histone H3 was virtually identical between acne and the two control groups. Our findings show the absence of increased keratinocyte proliferation in acne vulgaris. Alternative mechanisms are likely responsible for infundibular hyperkeratinization in acne pathogenesis. PMID- 29582470 TI - Considering dominance in reduced single-step genomic evaluations. AB - Single-step models including dominance can be an enormous computational task and can even be prohibitive for practical application. In this study, we try to answer the question whether a reduced single-step model is able to estimate breeding values of bulls and breeding values, dominance deviations and total genetic values of cows with acceptable quality. Genetic values and phenotypes were simulated (500 repetitions) for a small Fleckvieh pedigree consisting of 371 bulls (180 thereof genotyped) and 553 cows (40 thereof genotyped). This pedigree was virtually extended for 2,407 non-genotyped daughters. Genetic values were estimated with the single-step model and with different reduced single-step models. Including more relatives of genotyped cows in the reduced single-step model resulted in a better agreement of results with the single-step model. Accuracies of genetic values were largest with single-step and smallest with reduced single-step when only the cows genotyped were modelled. The results indicate that a reduced single-step model is suitable to estimate breeding values of bulls and breeding values, dominance deviations and total genetic values of cows with acceptable quality. PMID- 29582471 TI - Characterization of transcriptional complexity during pre-implantation development of the yak (Bos grunniens) using RNA-Seq. AB - The objective of this study was to investigate the mechanism that regulates pre implantation development of the yak (Bos grunniens). We determined the transcriptomes of in vitro-produced yak embryos at two-cell, four-cell, eight cell stages, and morula and blastocyst using the Illumina RNA-seq for the first time. We obtained 47.36-50.86 million clean reads for each stage, of which, 85.65%-90.02% reads were covered in the reference genome. A total of 17,368 genes were expressed during the two-cell stage to blastocyst of the yak, of which 7,236 genes were co-expressed at all stages, whereas 10,132 genes were stage-specific expression. Transcripts from 9,827 to 14,893 different genes were detected in various developmental stages. When |log2 ratio| >= 1 and q-value <0.05 were set as thresholds for identifying differentially expressed genes (DEGs), we detected a total of 6,922-10,555 DEGs between any two consecutive stages. The GO distributions of these DEGs were classified into three categories: biological processes (23 terms), cellular components (22 terms) and molecular functions (22 terms). Pathway analysis revealed 310 pathways of the DEGs that were operative in early pre-implantation yak development, of which 32 were the significantly enriched pathways. In conclusion, this is the first report to investigate the mechanism that regulates yak embryonic development using high-throughput sequencing, which provides a comprehensive framework of transcriptome landscapes of yak pre-implantation embryos. PMID- 29582472 TI - Diaryl-1,2,3-Triazolylidene Platinum(II) Complexes. AB - Control of the excited state geometry by rational ligand design leads to a new class of phosphorescent emitters with extraordinary photophysical properties. Extension of the pi-system in the triplet state leading to a significant bathochromic shift of the emission was avoided by introduction of additional steric demand. We report the synthesis, characterization and photophysical properties of novel platinum(II) complexes bearing C^C* cyclometalated mesoionic carbene (MIC) with different beta-diketonate ligands. The MIC ligand precursors were prepared from 1-phenyl-1,2,3-triazole using arylation protocols, introducing phenyl or mesityl functionalities. A solid state structure confirming the NMR assignments is presented. The emission properties were investigated in detail at room temperature and 77 K and are supported by DFT calculations and cyclic voltammetry. All complexes, with emission maxima between 502-534 nm, emit with quantum efficiencies ranging from 70-84 % in PMMA films. PMID- 29582473 TI - Prolactin as a candidate sebotrop(h)ic hormone? AB - Recognised for its key role in lactation, it is less well appreciated that the neurohormone prolactin (PRL) is actually one of the most pleiotropic hormones known. Not only does PRL exert both tropic and trophic effects in a wide range of tissues, but it is also expressed in human skin and hair follicles and regulates multiple complex cutaneous functions, including keratin expression and hair growth. Despite several clinical indications that PRL may also play a role in sebaceous gland (SG) biology, the effects of PRL on SG function have received little attention. In this Viewpoint essay, we argue that PRL may be a sebotrop(h)ic hormone and could represent a novel therapeutic target in human dermatoses affecting the SG. We provide preliminary evidence in support of this hypothesis (based on findings in human skin organ culture) and chart the major open questions in SG biology and pathology from a PRL research perspective. We close by delineating how these questions can be experimentally addressed so as to identify new therapeutic strategies that are either sebogenic or sebostatic, for example in the management of acne and cutaneous ageing. PMID- 29582474 TI - Dual kidney transplantation as a strategy to use expanded criteria donors: a systematic review. AB - The objective of this review was to assess whether dual kidney transplantation (DKT) is better than single KT (SKT) for optimizing the use of expanded criteria donor kidneys. We did a systematic literature search and meta-analyses when possible, pooling data for calculating relative risks (RR) of major outcomes. Twenty-five studies met the inclusion criteria. One-year serum creatinine was better after DKT vs. SKT (mean difference -0.27 [-0.37, -0.17], P < 0.001), with less incidence of acute rejection (RR 0.66 [0.52, 0.85], P < 0.001) and without differences at five years. Less DGF was seen in DKT (RR 0.88 [0.76, 1.02], P = 0.09). Mortality at 1 and 3 years was similar after dual or SKT, but mortality at five years was lower after DKT (RR 0.71 [0.53, 0.94], P = 0.02). One-year graft loss was similar between dual (n = 4158) and SKT (n = 51 800) (RR 0.97 [0.87, 1.09], P = 0.62). Three- and five-year graft loss was not considered because of high heterogeneity between studies. In conclusion, short-term graft function and long-term patient survival are better in recipients receiving DKT vs. SKT. However, these differences are based on few retrospective reports with a relatively low number of cases. Good quality randomized controlled trials are needed to assess whether the investment of two kidneys in one recipient is justified in face of the current organ shortage. PMID- 29582475 TI - First-in-human experience of left atrial appendage occlusion with the steerable FuStar sheath. AB - BACKGROUND: Due the wide variability of left atrial appendage morphology left atrial appendage occlusion (LAAO) remains a challenging procedure. The steerable FuStar delivery sheath was designed to allow both, transseptal access and delivery of percutaneous devices. We here report the first-in-human experience of LAAO with the FuStar sheath. METHODS: Twenty patients (76.6 +/- 8.4 years; 12 (60%) males; CHA2 DS2 -VASc score: 5.0 +/- 2) with non-valvular fibrillation and contraindications to oral anticoagulation underwent LAAO with the LAmbre device using the FuStar steerable sheath (Lifetech Scientific Corp., Shenzhen, China) at two german centers. RESULTS: Successful device implantation was achieved in all patients (100%). No periprocedural complications were observed. Procedure time, fluoroscopy time, contrast media, and radiation dose were 23.4 min +/- 9.2, 11.9 min +/- 4.1, 96.2 mL +/- 45.7, and 2718.4 cG*cm2 +/- 3835.3, respectively. CONCLUSION: This study demonstrates the feasibility and safety of the steerable FuStar sheath for LAAO. PMID- 29582477 TI - Immune molecular profiling of whole blood drawn from a non-human primate cardiac xenograft model treated with anti-CD154 monoclonal antibodies. AB - Most studies of xenografts have been carried out with complex immunosuppressive regimens to prevent immune rejection; however, such treatments may be fatal owing to unknown causes. Here, we performed immune molecular profiling following anti CD154 monoclonal antibody (mAb) treatment in heterotopic abdominal cardiac xenografts from alpha-1,3-galactosyltransferase-knockout pigs into cynomolgus monkeys to elucidate the mechanisms mediating the undesirable fatal side effects of immunosuppressive agents. Blood samples were collected from healthy monkeys as control and then at 2 days after xenograft transplantation and just before humane euthanasia; 94 genes related to the immune system were analyzed. The basic immunosuppressive regimen included cobra venom factor, anti-thymocyte globulin, and rituximab, with and without anti-CD154 mAbs. The maintenance therapy was followed with tacrolimus, MMF, and methylprednisolone. The number of upregulated genes was initially decreased on Day 2 (-/+ anti-CD154 mAb, 22/13) and then increased before euthanasia in recipients treated with anti-CD154 mAbs (-/+ anti CD154 mAb, 30/37). The number of downregulated genes was not affected by anti CD154 mAb treatment. Additionally, the number of upregulated genes increased over time for both groups. Interestingly, treatment with anti-CD154 mAbs upregulated coagulation inducers (CCL2/IL6) before euthanasia. In conclusion, immunosuppressive regimens used for cardiac xenografting affected upregulation of 6 inflammation genes (CXCL10, MPO, MYD88, NLRP3, TNFalpha, and TLR1) and downregulation of 8 genes (CCR4, CCR6, CD40, CXCR3, FOXP3, GATA3, STAT4, and TBX21). PMID- 29582478 TI - Advanced Materials by Atom Transfer Radical Polymerization. AB - Atom transfer radical polymerization (ATRP) has been successfully employed for the preparation of various advanced materials with controlled architecture. New catalysts with strongly enhanced activity permit more environmentally benign ATRP procedures using ppm levels of catalyst. Precise control over polymer composition, topology, and incorporation of site specific functionality enables synthesis of well-defined gradient, block, comb copolymers, polymers with (hyper)branched structures including stars, densely grafted molecular brushes or networks, as well as inorganic-organic hybrid materials and bioconjugates. Examples of specific applications of functional materials include thermoplastic elastomers, nanostructured carbons, surfactants, dispersants, functionalized surfaces, and biorelated materials. PMID- 29582476 TI - Cell Membrane Coating Nanotechnology. AB - Nanoparticle-based therapeutic, prevention, and detection modalities have the potential to greatly impact how diseases are diagnosed and managed in the clinic. With the wide range of nanomaterials available, the rational design of nanocarriers on an application-specific basis has become increasingly commonplace. Here, a comprehensive overview is provided on an emerging platform: cell-membrane-coating nanotechnology. As a fundamental unit of biology, cells carry out a wide range of functions, including the remarkable ability to interface and interact with their surrounding environment. Instead of attempting to replicate such functions via synthetic techniques, researchers are now directly leveraging naturally derived cell membranes as a means of bestowing nanoparticles with enhanced biointerfacing capabilities. This top-down technique is facile, highly generalizable, and has the potential to greatly augment existing nanocarriers. Further, the introduction of a natural membrane substrate onto nanoparticles surfaces has enabled additional applications beyond those traditionally associated with nanomedicine. Despite its relative youth, there exists an impressive body of literature on cell membrane coating, which is covered here in detail. Overall, there is still significant room for development, as researchers continue to refine existing workflows while finding new and exciting applications that can take advantage of this developing technology. PMID- 29582479 TI - Comparative assessment of growth performance of three different indigenous goat breeds exposed to summer heat stress. AB - A study was conducted to assess comparatively the growth performance of three different indigenous goat breeds during exposure to summer heat stress. The primary objective of the study was to observe the heat stress impact on the growth performance based on the body weight changes, allometric measurements, growth hormone (GH) concentration and peripheral blood mononuclear cell (PBMC) Insulin-like growth factor-1 (IGF-1) mRNA expression pattern during the summer season in comparison with the local breed (Osmanabadi). Thirty-six ten-month- to one-year-old female goats of Osmanabadi, Malabari and Salem Black breeds were randomly divided into six groups, OC (n = 6; Osmanabadi control), OHS (n = 6; Osmanabadi heat stress), MC (n = 6; Malabari control), MHS (n = 6; Malabari heat stress), SBC (n = 6; Salem Black control) and SBHS (n = 6; Salem Black heat stress). Body weight was recorded at weekly intervals, whereas other growth and allometric measurements and blood collection were carried out at fortnightly intervals. Breed factor significantly (p < .05) influenced only few growth variables such as body weight, body mass index (BMI) and body condition score (BCS). However, heat stress treatment significantly (p < .05) reduced all growth parameters expect BMI. Further, the heat stress significantly (p < .01) increased plasma GH concentration in goats with significantly higher (p < .05) concentration recorded in OHS. Among the stress groups, the lower (p < .05) PBMC IGF-1 mRNA expression was recorded in OHS, while the higher (p < .05) expression was observed in SBHS indicating the extreme adaptive capability of Salem Black breed. Thus, the results indicated that the Salem Black breed performed much better compared to both Osmanabadi and Malabari breeds indicating the superior ability of this breed to adapt to heat stress challenges. The results also indicated that plasma GH and IGF-1 gene may act as ideal biomarkers for assessing the heat stress impact on growth performance in indigenous goats. PMID- 29582482 TI - Metal-Organic Frameworks for Separation. AB - Separation is an important industrial step with critical roles in the chemical, petrochemical, pharmaceutical, and nuclear industries, as well as in many other fields. Although much progress has been made, the development of better separation technologies, especially through the discovery of high-performance separation materials, continues to attract increasing interest due to concerns over factors such as efficiency, health and environmental impacts, and the cost of existing methods. Metal-organic frameworks (MOFs), a rapidly expanding family of crystalline porous materials, have shown great promise to address various separation challenges due to their well-defined pore size and unprecedented tunability in both composition and pore geometry. In the past decade, extensive research is performed on applications of MOF materials, including separation and capture of many gases and vapors, and liquid-phase separation involving both liquid mixtures and solutions. MOFs also bring new opportunities in enantioselective separation and are amenable to morphological control such as fabrication of membranes for enhanced separation outcomes. Here, some of the latest progress in the applications of MOFs for several key separation issues, with emphasis on newly synthesized MOF materials and the impact of their compositional and structural features on separation properties, are reviewed and highlighted. PMID- 29582480 TI - Evaluation of updated sepsis scoring systems and systemic inflammatory response syndrome criteria and their association with sepsis in equine neonates. AB - BACKGROUND: The original equine sepsis score provided a method of identifying foals with sepsis. New variables associated with sepsis have been evaluated, but the sepsis score has not been updated. OBJECTIVES: To evaluate the sensitivity and specificity of 2 updated sepsis scores and the systemic inflammatory response syndrome (SIRS) criteria in regard to detecting sepsis in foals. ANIMALS: Two hundred and seventy-three ill foals and 25 healthy control foals. METHODS: Historical, physical examination, and clinicopathologic findings were used to calculate the original sepsis score and 2 updated sepsis scores. SIRS criteria were also evaluated. Sepsis scores and positive SIRS scores were statistically compared to foals with sepsis. RESULTS: One-hundred and twenty-six foals were septic and 147 sick-nonseptic. The original and updated sepsis scores were significantly higher in septic foals as compared to sick-nonseptic and healthy foals. The sensitivity and specificity of the updated sepsis scores to predict sepsis were not significantly better than those of the original sepsis score. One hundred and twenty-seven of 273 (46.5%) foals met the original SIRS criteria and 88/273 (32%) foals met the equine neonatal SIRS criteria. The original SIRS criteria had similar sensitivity and specificity for predicting sepsis as did the 3 sepsis scores in our study. CONCLUSIONS AND CLINICAL IMPORTANCE: The updated sepsis scores did not provide improved ability in predicting sepsis. Fulfilling the original SIRS criteria provided similar sensitivity and specificity in predicting sepsis as the modified sepsis score and might serve as a diagnostic aid in identifying foals at risk for sepsis. PMID- 29582481 TI - Resveratrol-cyclodextrin complex affects the expression of genes associated with lipid metabolism in bovine in vitro produced embryos. AB - Antioxidants have been widely used during in vitro production to decrease the negative effect of reactive oxygen species. It was reported that the complex resveratrol-methyl beta-cyclodextrin (RV-CD) improves resveratrol's stability and bioavailability and increases its antioxidant activity. This study evaluates the effect of RV-CD during in vitro oocyte maturation (IVM) or in vitro embryo culture (IVC) on developmental competence and quantitative changes in gene expression of developmental important genes. In experiment 1, RV-CD was added to IVM media and maturation level, embryo development and oocytes, cumulus cells, and blastocysts gene expression by RT-qPCR were examined. In experiment 2, presumptive zygotes were cultured in SOF supplemented with RV-CD and embryo development and blastocysts gene expression by RT-qPCR were studied. A group without RV-CD (control- ) and a group with cyclodextrin (control+ ) were included. No differences were found in cleavage rate or blastocyst yield between groups. However, the expression of LIPE was higher in blastocysts derived from oocytes treated with resveratrol compared with control groups (p < .05). Blastocysts produced by IVC with resveratrol showed that RV-CD could modify the expression of genes related to lipid metabolism (CYP51A1, PNPLA2 and MTORC1) compared with control groups (p < .05). RV-CD in the IVM and IVC media could reduce accumulated fat by increasing lipolysis and suppressing lipogenesis of blastocysts. PMID- 29582483 TI - Stretchable All-Gel-State Fiber-Shaped Supercapacitors Enabled by Macromolecularly Interconnected 3D Graphene/Nanostructured Conductive Polymer Hydrogels. AB - Nanostructured conductive polymer hydrogels (CPHs) have been extensively applied in energy storage owing to their advantageous features, such as excellent electrochemical activity and relatively high electrical conductivity, yet the fabrication of self-standing and flexible electrode-based CPHs is still hampered by their limited mechanical properties. Herein, macromolecularly interconnected 3D graphene/nanostructured CPH is synthesized via self-assembly of CPHs and graphene oxide macrostructures. The 3D hybrid hydrogel shows uniform interconnectivity and enhanced mechanical properties due to the strong macromolecular interaction between the CPHs and graphene, thus greatly reducing aggregation in the fiber-shaping process. A proof-of-concept all-gel-state fibrous supercapacitor based on the 3D polyaniline/graphene hydrogel is fabricated to demonstrate the outstanding flexibility and mouldability, as well as superior electrochemical properties enabled by this 3D hybrid hydrogel design. The proposed device can achieve a large strain (up to ~40%), and deliver a remarkable volumetric energy density of 8.80 mWh cm-3 (at power density of 30.77 mW cm-3 ), outperforming many fiber-shaped supercapacitors reported previously. The all-hydrogel design opens up opportunities in the fabrication of next generation wearable and portable electronics. PMID- 29582484 TI - Covalent Organic Frameworks as a Decorating Platform for Utilization and Affinity Enhancement of Chelating Sites for Radionuclide Sequestration. AB - The potential consequences of nuclear events and the complexity of nuclear waste management motivate the development of selective solid-phase sorbents to provide enhanced protection. Herein, it is shown that 2D covalent organic frameworks (COFs) with unique structures possess all the traits to be well suited as a platform for the deployment of highly efficient sorbents such that they exhibit remarkable performance, as demonstrated by uranium capture. The chelating groups laced on the open 1D channels exhibit exceptional accessibility, allowing significantly higher utilization efficiency. In addition, the 2D extended polygons packed closely in an eclipsed fashion bring chelating groups in adjacent layers parallel to each other, which may facilitate their cooperation, thereby leading to high affinity toward specific ions. As a result, the amidoxime functionalized COFs far outperform their corresponding amorphous analogs in terms of adsorption capacities, kinetics, and affinities. Specifically, COF-TpAb-AO is able to reduce various uranium contaminated water samples from 1 ppm to less than 0.1 ppb within several minutes, well below the drinking water limit (30 ppb), as well as mine uranium from spiked seawater with an exceptionally high uptake capacity of 127 mg g-1 . These results delineate important synthetic advances toward the implementation of COFs in environmental remediation. PMID- 29582485 TI - Uniaxial Alignment of Conjugated Polymer Films for High-Performance Organic Field Effect Transistors. AB - Polymer semiconductors have been experiencing a remarkable improvement in electronic and optoelectronic properties, which are largely related to the recent development of a vast library of high-performance, donor-acceptor copolymers showing alternation of chemical moieties with different electronic affinities along their backbones. Such steady improvement is making conjugated polymers even more appealing for large-area and flexible electronic applications, from distributed and portable electronics to healthcare devices, where cost-effective manufacturing, light weight, and ease of integration represent key benefits. Recently, a strong boost to charge carrier mobility in polymer-based field-effect transistors, consistently achieving the range from 1.0 to 10 cm2 V-1 s-1 for both holes and electrons, has been given by uniaxial backbone alignment of polymers in thin films, inducing strong transport anisotropy and favoring enhanced transport properties along the alignment direction. Herein, an overview on this topic is provided with a focus on the processing-structure-property relationships that enable the controlled and uniform alignment of polymer films over large areas with scalable processes. The key aspects are specific molecular structures, such as planarized backbones with a reduced degree of conformational disorder, solution formulation with controlled aggregation, and deposition techniques inducing suitable directional flow.

AB - A series of chiral and helical PtII -Salen complexes with 1,1'-binaphthyl linkers were synthesized and characterized. Owing to the restriction of intramolecular motions of central 1,1'-binaphthyls, the complexes exhibit unusual near-infrared aggregation-induced phosphorescence (AIP). The (R)/(S) enantiopure complexes were characterized by X-ray diffraction, circular dichroism spectra, time-dependent density functional theory calculations, and circularly polarized luminescence (CPL). The present work explores the use of tetradentate ligands that can be easily prepared from commercially available enantiopure compounds, and the subsequent preparation of stable CPL-active square planar PtII complexes with AIP effect that may have interest in many applications.

AB - Precise patterning of polymer-based biomaterials for functional bio nanostructures has extensive applications including biosensing, tissue engineering, and regenerative medicine. Remarkable progress is made in both top down (based on lithographic methods) and bottom-up (via self-assembly) approaches with natural and synthetic biopolymers. However, most methods only yield 2D and pseudo-3D structures with restricted geometries and functionalities. Here, it is reported that precise nanostructuring on genetically engineered spider silk by accurately directing ion and electron beam interactions with the protein's matrix at the nanoscale to create well-defined 2D bionanopatterns and further assemble 3D bionanoarchitectures with shape and function on demand, termed "Protein Bricks." The added control over protein sequence and molecular weight of recombinant spider silk via genetic engineering provides unprecedented lithographic resolution (approaching the molecular limit), sharpness, and biological functions compared to natural proteins. This approach provides a facile method for patterning and immobilizing functional molecules within nanoscopic, hierarchical protein structures, which sheds light on a wide range of biomedical applications such as structure-enhanced fluorescence and biomimetic microenvironments for controlling cell fate. PMID- 29582488 TI - Binaural responses in the auditory midbrain of chicken (Gallus gallus). AB - The auditory midbrain is the location in which neurons represent binaural acoustic information necessary for sound localization. The external nucleus of the midbrain inferior colliculus (IC) of the barn owl is a classic example of an auditory space map, but it is unknown to what extent the principles underlying its formation generalize to other, less specialized animals. We characterized the spiking responses of 139 auditory neurons in the IC of the chicken (Gallus gallus) in vivo, focusing on their sensitivities to the binaural localization cues of interaural time (ITD) and level (ILD) differences. Most units were frequency-selective, with best frequencies distributed unevenly into low frequency and high-frequency (> 2 kHz) clusters. Many units showed sensitivity to either ITD (65%) or ILD (66%) and nearly half to both (47%). ITD selectivity was disproportionately more common among low-frequency units, while ILD-only selective units were predominantly tuned to high frequencies. ILD sensitivities were diverse, and we thus developed a decision tree defining five types. One rare type with a bell-like ILD tuning was also selective for ITD but typically not frequency-selective, and thus matched the characteristics of neurons in the auditory space map of the barn owl. Our results suggest that generalist birds such as the chicken show a prominent representation of ITD and ILD cues in the IC, providing complementary information for sound localization, according to the duplex theory. A broadband response type narrowly selective for both ITD and ILD may form the basis for a representation of auditory space.

AB - ISSUES: This overview of reviews will synthesise information from existing reviews to provide a summary of the evidence for universal alcohol and illicit drug prevention strategies across different intervention settings. APPROACH: Academic databases, including Medline, EMBASE and PsycInfo were searched on 1 August 2016. All reviews and meta-analyses of universal alcohol and drug prevention conducted since 2006 were included. The reviews included in this overview were grouped according to the different settings where prevention strategies have been applied (i.e. family, school, college, workplace, leisure, healthcare, community, media and policy). KEY FINDINGS: Fifty-two reviews met the inclusion criteria and were included in this report. There is sufficient evidence to support universal preventive interventions for alcohol in family and school settings. In terms of reducing drug use, there is sufficient evidence to support the use of school- and leisure-based universal primary prevention strategies. Based on evidence published in the last 10 years, mass media campaigns to do not appear to be effective in reducing drug use. More evidence is needed to support preventive interventions in college, workplace, healthcare and community settings. IMPLICATIONS: Through the identification of settings where preventive interventions are effective, this overview can be used to guide alcohol and drug policy and the allocation of resources. CONCLUSION: The evidence base for universal prevention in several settings could be strengthened, guiding priorities for future research.

AB - The Schulze-Hardy rule is a well-established observation in colloid science (can be derived from the DLVO theory) that demonstrates the relationship between the critical coagulation concentration (CCC) of colloids and the valence of extra counterionic electrolytes (z), with a simple mathematical relationship of CCC~z-6 . Here the Schulze-Hardy Rule is expanded to much smaller, nano-scaled soluble macroions in aqueous solution, by examining the stability of the macroions in the presence of additional electrolytes. The CCC values of the macroions follow the general trend of CCC~z-n but the n value is significantly dependent on the surface charge density of the macroions, ranging from n=2 at very low surface charge density to n=6 at a high surface charge density. In addition, different cations with the same valence showed clear different impacts on the CCC values, with an interesting trend being connected to the Hofmeister series originally discovered in protein solutions.

AB - Melanoma is the most lethal cutaneous cancer with a highly aggressive and metastatic phenotype. While recent genetic and epigenetic studies have shed new insights into the mechanism of melanoma development, the involvement of regulatory non-coding RNAs remain unclear. Long non-coding RNAs (lncRNAs) are a group of endogenous non-protein-coding RNAs with the capacity to regulate gene expression at multiple levels. Recent evidences have shown that lncRNAs can regulate many cellular processes, such as cell proliferation, differentiation, migration and invasion. In the melanoma, deregulation of a number of lncRNAs, such as HOTAIR, MALAT1, BANCR, ANRIL, SPRY-IT1 and SAMMSON, have been reported. Our review summarizes the functional role of lncRNAs in melanoma and their potential clinical application for diagnosis, prognostication and treatment. PMID- 29582493 TI - Hydrogenation of Fluorographite and Fluorographene: An Easy Way to Produce Highly Hydrogenated Graphene. AB - Fluorographene is an excellent precursor for the synthesis of graphene derivatives. Relative to pure graphene, fluorographene possesses higher reactivity and, in comparison with graphene oxide, is also homogenous in composition, which enables the preparation of well-defined materials. Recently, it has been shown that several graphene derivatives can be synthesized from fluorographene, thus yielding various products such as graphene acid or alkylated graphene. This study focuses on the hydrogenation of fluorographene by using various hydrogenation reactions, including the use complex hydrides and solvated electrons in different media. In addition, a comparison of these reactions shows that fluorinated graphite has significantly lower reactivity than fluorographene. The conversion rates of these reactions are higher when fluorographene is used relative to fluorographite. These reactions can be used to tune the hydrogen/fluorine composition on a graphene backbone. PMID- 29582495 TI - Targeting Alzheimer's disease with gene and cell therapies. AB - Alzheimer's disease (AD) causes dementia in both young and old people affecting more than 40 million people worldwide. The two neuropathological hallmarks of the disease, amyloid beta (Abeta) plaques and neurofibrillary tangles consisting of protein tau are considered the major contributors to the disease. However, a more complete picture reveals significant neurodegeneration and decreased cell survival, neuroinflammation, changes in protein and energy homeostasis and alterations in lipid and cholesterol metabolism. In addition, gene and cell therapies for severe neurodegenerative disorders have recently improved technically in terms of safety and efficiency and have translated to the clinic showing encouraging results. Here, we review broadly current data within the field for potential targets that could modify AD through gene and cell therapy strategies. We envision that not only Abeta will be targeted in a disease modifying treatment strategy but rather that a combination of treatments, possibly at different intervention times may prove beneficial in curing this devastating disease. These include decreased tau pathology, neuronal growth factors to support neurons and modulation of neuroinflammation for an appropriate immune response. Furthermore, cell based therapies may represent potential strategies in the future. PMID- 29582494 TI - 1,2,4-trihydroxynaphthalene-2-O-beta-D-glucopyranoside delays amyloid-beta42 aggregation and reduces amyloid cytotoxicity. AB - Presently, misfolding and aggregation of amyloid-beta42 (Abeta42 ) are considered early events in Alzheimer's disease (AD) pathogenesis. The use of natural products to inhibit the aggregation process and to protect cells from cytotoxicity of early aggregate grown at the onset of the aggregation path is one of the promising strategies against AD. Recently, we have purified a new powerful antioxidant and inhibitor of Abeta42 aggregation from the leaves of Lawsonia inermis. The new compound was identified as a new Lawsoniaside; 1,2,4 trihydroxynaphthalene-2-O-beta-D-glucopyranoside (THNG). Herein, we show that THNG interferes with Abeta42 aggregation, inhibits its conformational change to a beta-sheet-rich structure, decreases its polymerization into large fibrillar species, reduces oxidative stress, and aggregate cytotoxicity. These results indicate that THNG has great potential as a neuroprotective and therapeutic agent against AD. (c) 2018 BioFactors, 44(3):272-280, 2018. PMID- 29582496 TI - Availability of alcohol: Location, time and ease of purchase in high- and middle income countries: Data from the International Alcohol Control Study. AB - INTRODUCTION AND AIMS: Cross-country studies on alcohol purchasing and access are rare. We examined where and when people access alcohol to understand patterns of availability across a range of middle- and high-income countries. DESIGN AND METHODS: Surveys of drinkers in the International Alcohol Control study in high income countries (Australia, England, Scotland, New Zealand and St Kitts and Nevis) and middle-income countries (Mongolia, South Africa, Peru, Thailand and Vietnam) were analysed. Measures were: location of purchase from on-premise and take-away outlets, proportion of alcohol consumed on-premise versus take-away outlets, hours of purchase, access among underage drinkers and time to access alcohol. RESULTS: On-premise purchasing was prevalent in the high-income countries. However, the vast majority of alcohol consumed in all countries, except St Kitts and Nevis (high-income), was take-away. Percentages of drinkers purchasing from different types of on-premise and take-away outlets varied between countries. Late purchasing was common in Peru and less common in Thailand and Vietnam. Alcohol was easily accessed by drinkers in all countries, including underage drinkers in the middle-income countries. DISCUSSION AND CONCLUSIONS: In nine out of 10 countries the vast majority of alcohol consumed was take-away. Alcohol was readily available and relatively easy for underage drinkers to access, particularly in the middle-income countries. Research is needed to assess the harms associated with take-away consumption including late at night. Attention is needed to address the easy access by underage drinkers in the middle income countries which has been less of a focus than in high-income countries. PMID- 29582497 TI - Emergency department risk factors for serious clinical deterioration in a paediatric hospital in Peru. AB - AIM: Identification of critically ill children upon presentation to the emergency department (ED) is challenging, especially when resources are limited. The objective of this study was to identify ED risk factors associated with serious clinical deterioration (SCD) during hospitalisation in a resource-limited setting. METHODS: A retrospective case-control study of children less than 18 years of age presenting to the ED in a large, freestanding children's hospital in Peru was performed. Cases had SCD during the first 7 days of hospitalisation whereas controls did not. Information collected during initial ED evaluation was used to identify risk factors for SCD. RESULTS: A total of 120 cases and 974 controls were included. In univariate analysis, young age, residence outside Lima, evaluation at another facility prior to ED presentation, congenital malformations, abnormal neurologic baseline, co-morbidities and a prior paediatric intensive care unit admission were associated with SCD. In multivariate analysis, age < 12 months, residence outside Lima and evaluation at another facility prior to ED presentation remained associated with SCD. In addition, comatose neurological status, hypoxaemia, tachycardia, tachypnoea and temperature were also associated with SCD. CONCLUSIONS: Many risk factors for SCD during hospitalisation can be identified upon presentation to the ED. Using these factors to adjust monitoring during and after the ED stay has the potential to decrease SCD events. Further studies are needed to determine whether this holds true in other resource-limited settings. PMID- 29582498 TI - Requirement of Leptinotarsa decemlineata gene within the 74EF puff for larval pupal metamorphosis and appendage growth. AB - Two Drosophila melanogaster E-twenty-six domain transcription factor isoforms (E74A and E74B) act differentially at the start of the 20-hydroxyecdysone (20E) signalling cascade to regulate larval-pupal metamorphosis. In the present paper, we identified the two isoforms (LdE74A and LdE74B) in Leptinotarsa decemlineata. During the larval development stage, the mRNA transcript levels of the two LdE74 isoforms were correlated with circulating 20E titres. In vitro midgut culture and in vivo dietary supplementation with 20E revealed that the presence of 20E induced expression peaks of both LdE74A and LdE74B, with similar patterns observed for the two isoforms. Moreover, the mRNA transcript levels of both LdE74A and LdE74B isoforms were significantly downregulated in the L. decemlineata ecdysone receptor RNA interference (RNAi) specimens, but not in the LdE75 RNAi beetles. Ingestion of 20E reduced the larval fresh weights and shortened the larval development period, irrespective of knockdown of LdE74 or not. RNAi of LdE74 did not affect 20E-induced expression of the Ecdysone induced protein 75-hormone receptor 3-fushi tarazu factor 1 (E75-HR3-FTZ-F1) transcriptional cascade. Thus, it seems that LdE74 mediates 20E signalling independent of the E75-HR3-FTZ-F1 transcriptional cascade. Furthermore, silencing of both LdE74 isoforms caused failure of ecdysis. Most of the LdE74 RNAi beetles remained as prepupae. The LdE74 RNAi prepupae exhibited adult character-like forms underneath after removal of the apolysed larval cuticle. Their appendages such as antennae, legs and wings were shorter than those of control larvae. Only a few LdE74 RNAi larvae finally became deformed pupae, with shortened antennae and legs. Therefore, LdE74 is required for larval-pupal metamorphosis and appendage growth in L. decemlineata. PMID- 29582499 TI - Knowledge and behaviors in relation to antibiotic use among rural residents in Anhui, China. AB - OBJECTIVES: To examine antibiotic-related knowledge and behaviors in rural Anhui, identify factors associated with knowledge, and explore the relationship between knowledge and antibiotic use. METHODS: Cross-sectional study of a random sample of 2760 residents of rural China using structured interviews. RESULTS: The response rate was 94.6%. A total of 2390 respondents (91.6%) believed that antibiotics can control viruses; 2007 (77.5%) respondents thought that a combination of antibiotics is more effective than a single class; and 590 (22.6%) were able to name at least one disbenefit of using antibiotics. Multivariate analysis revealed those with a higher educational level and younger age group had greater knowledge of antibiotics (OR 2.54 and 0.77, respectively). Self medication was common with 1052 (out of 2274 responses, 46.3%) of participants use over the counter or leftover medicines for common infections. Greater knowledge was associated with buying drugs without prescription (aOR 2.02; 95% CI, 1.29-3.17) and using leftover medication (aOR 2.80; 95% CI, 1.55-5.06). CONCLUSION: Knowledge about antibiotics was low and reported use high. Worryingly those with greater knowledge had less desirable behaviors that highlights the urgent need for multifaceted interventions to change behavior. PMID- 29582500 TI - The stereodynamics of macrocyclic succinimide-thioethers. AB - Maleimide-thiol coupling is a popular bioconjugation strategy, but little is known about the stereoselectivity and the stereodynamics of the succinimide thioether formed in a biopolymer environment. We used thiol 1,4-addition for the macrocyclisation of 5 designed pentapeptides with the ringsize of hexapeptides because they incorporate the succinimide thioether (4-8). Both succinimide diastereomers are observed in the constrained macrocyclic rings in each case. In spite of the low diastereoselectivity of the macrocyclisation reaction, there is a significant influence of the amino acid environment on the epimerization rate of the succinimide. Its half life can be as short as several hours at room temperature when Gly is the amino acid following the succinimide (peptide 8). On the contrary, no epimerization is detectable even after several weeks in the case of d-Phe C-terminal to the succinimide in peptide 4. Already the small selection of examples shows how big the differences in epimerization rates can be and that the local environment has a significant influence. The variation of amino acids in the vicinity of the ligation site points the way towards the synthesis of bioconjugates which are obtained as stable and separable diastereomers. PMID- 29582501 TI - The symbolic representation of community in social isolation and loneliness among older people: Insights for intervention from a rural Irish case study. AB - Social isolation and loneliness are common experiences of ageing in rural communities. Policy responses and interventions for social isolation and loneliness in later life are shaped by sociocultural understandings of place, relationships and social interaction. This study examined how representations of rural community in Ireland influenced the focus, relationships and activities within a befriending intervention designed to tackle social isolation and loneliness. Through a qualitative case study conducted in 2014, the symbolic meaning of the intervention was explored using interviews and focus groups with participants (8 befriended, 11 befrienders and 3 community workers) from one befriending programme in rural Ireland. Reflected in the programme was a representation of a rural community in decline with concern for the impact on older people. There was a valuing of the traditional community defined by geographical place, perceptions of similarity among its members, and values of solidarity and mutual support. The befriending intervention represented a commitment to intra-community solidarity and a desire by many for authentic befriending relationships that mirrored understandings of relationships within the traditional community. Identifying and alleviating social isolation and loneliness imply a set of normative values about community and the optimal social relationships within community. This paper proposes that there is a need to consider the role played by understandings of community in shaping context sensitive interventions to counter social isolation and loneliness in later life. PMID- 29582502 TI - The role of the right temporo-parietal junction in social decision-making. AB - Identifying someone else's noncooperative intentions can prevent exploitation in social interactions. Hence, the inference of another person's mental state might be most pronounced in order to improve social decision-making. Here, we tested the hypothesis that brain regions associated with Theory of Mind (ToM), particularly the right temporo-parietal junction (rTPJ), show higher neural responses when interacting with a selfish person and that the rTPJ-activity as well as cooperative tendencies will change over time. We used functional magnetic resonance imaging (fMRI) and a modified prisoner's dilemma game in which 20 participants interacted with three fictive playing partners who behaved according to stable strategies either competitively, cooperatively or randomly during seven interaction blocks. The rTPJ and the posterior-medial prefrontal cortex showed higher activity during the interaction with a competitive compared with a cooperative playing partner. Only the rTPJ showed a high response during an early interaction phase, which preceded participants increase in defective decisions. Enhanced functional connectivity between the rTPJ and the left hippocampus suggests that social cognition and learning processes co-occur when behavioral adaptation seems beneficial. PMID- 29582503 TI - Th-17 response and antimicrobial peptide expression are uniformly expressed in gastric mucosa of Helicobacter pylori-infected patients independently of their clinical outcomes. AB - BACKGROUND: The pathological determinism of H. pylori infection is explained by complex interplay between bacterial virulence and host inflammatory response. In a large prospective multicenter clinical study, Th17 response, expression of antimicrobial peptides (AMPs), cagA and vacA status, and bacterial density were investigated in the gastric mucosa of H. pylori -infected patients. MATERIALS AND METHODS: Gastric inflammatory response was analyzed by RT-qPCR for quantification of Th17 cytokines (IL-17A, IL-22), CXCL-8, and AMPs (BD2 and S100A9) mRNA levels in gastric biopsies. Detection and genotyping of H. pylori strains were achieved by bacterial culture and PCR. RESULTS: Among 787 patients screened for H. pylori, 269 were analyzed (147 H. pylori -infected and 122 uninfected patients). In H. pylori -infected patients, distribution was 83 gastritis, 12 duodenal ulcers, 5 gastric ulcers, and 47 precancerous and cancerous lesions. CXCL-8, IL-17A, BD2, and S100A9 mRNA levels were significantly increased in H. pylori -infected patients but, surprisingly, IL-22 was not, and no difference was shown between H. pylori -related diseases. A positive correlation was identified between S100A9 expression and bacterial density. Although expression of the virulence genes cagA and vacA did not impact inflammatory response, patients infected with a cagA positive strain were associated with severe H. pylori -related diseases. CONCLUSION: This study showed that CXCL-8, IL-17A, and AMPs are not differently expressed according to the various H. pylori -related diseases. The clinical outcome determinism of H. pylori infection is most likely not driven by gastric inflammation but rather tends to mainly influenced by bacterial virulence factors.

AB - In vivo morphological study of the human habenula, a pair of small epithalamic nuclei adjacent to the dorsomedial thalamus, has recently gained significant interest for its role in reward and aversion processing. However, segmenting the habenula from in vivo magnetic resonance imaging (MRI) is challenging due to the habenula's small size and low anatomical contrast. Although manual and semi automated habenula segmentation methods have been reported, the test-retest reproducibility of the segmented habenula volume and the consistency of the boundaries of habenula segmentation have not been investigated. In this study, we evaluated the intra- and inter-site reproducibility of in vivo human habenula segmentation from 3T MRI (0.7-0.8 mm isotropic resolution) using our previously proposed semi-automated myelin contrast-based method and its fully-automated version, as well as a previously published manual geometry-based method. The habenula segmentation using our semi-automated method showed consistent boundary definition (high Dice coefficient, low mean distance, and moderate Hausdorff distance) and reproducible volume measurement (low coefficient of variation). Furthermore, the habenula boundary in our semi-automated segmentation from 3T MRI agreed well with that in the manual segmentation from 7T MRI (0.5 mm isotropic resolution) of the same subjects. Overall, our proposed semi-automated habenula segmentation showed reliable and reproducible habenula localization, while its fully-automated version offers an efficient way for large sample analysis. PMID- 29582506 TI - Exploring hydrophobicity limits of polyproline helix with oligomeric octahydroindole-2-carboxylic acid. AB - The polyproline-II helix is the most extended naturally occurring helical structure and is widely present in polar, exposed stretches and "unstructured" denatured regions of polypeptides. Can it be hydrophobic? In this study, we address this question using oligomeric peptides formed by a hydrophobic proline analogue, (2S,3aS,7aS)-octahydroindole-2-carboxylic acid (Oic). Previously, we found the molecular principles underlying the structural stability of the polyproline-II conformation in these oligomers, whereas the hydrophobicity of the peptide constructs remains to be examined. Therefore, we investigated the octan-1 ol/water partitioning and inclusion in detergent micelles of the oligo-Oic peptides. The results showed that the hydrophobicity is remarkably enhanced in longer oligomeric sequences, and the oligo-Oic peptides with 3 to 4 residues and higher are specific towards hydrophobic environments. This contrasts significantly to the parent oligoproline peptides, which were moderately hydrophilic. With these findings, we have demonstrated that the polyproline-II structure is compatible with nonpolar media, whereas additional manipulations of the terminal functionalities feature solubility in extremely nonpolar solvents such as hexane. PMID- 29582507 TI - The impact of caffeine consumption during 50 hr of extended wakefulness on glucose metabolism, self-reported hunger and mood state. AB - Caffeine is known for its capacity to mitigate performance decrements. The metabolic side-effects are less well understood. This study examined the impact of cumulative caffeine doses on glucose metabolism, self-reported hunger and mood state during 50 hr of wakefulness. In a double-blind laboratory study, participants were assigned to caffeine (n = 9, 6M, age 21.3 +/- 2.1 years; body mass index 21.9 +/- 1.6 kg/m2 ) or placebo conditions (n = 8, 4M, age 23.0 +/- 2.8 years; body mass index 21.8 +/- 1.6 kg/m2 ). Following a baseline sleep (22:00 hours-08:00 hours), participants commenced 50 hr of sleep deprivation. Meal timing and composition were controlled throughout the study. Caffeine (200 mg) or placebo gum was chewed for 5 min at 01:00 hours, 03:00 hours, 05:00 hours and 07:00 hours during each night of sleep deprivation. Continual glucose monitors captured interstitial glucose 2 hr post-breakfast, at 5-min intervals. Hunger and mood state were assessed at 10:00 hours, 16:30 hours, 22:30 hours and 04:30 hours. Caffeine did not affect glucose area under the curve (p = 0.680); however, glucose response to breakfast significantly increased after 2 nights of extended wakefulness compared with baseline (p = 0.001). There was a significant main effect of day, with increased tiredness (p < 0.001), mental exhaustion (p < 0.001), irritability (p = 0.002) and stress (p < 0.001) on the second day of extended wake compared with day 1. Caffeine attenuated the rise in tiredness (p < 0.001), mental exhaustion (p = 0.044) and irritability (p = 0.018) on day 1 but not day 2. Self-reported hunger was not affected by sleep deprivation or caffeine. These data confirm the effectiveness of caffeine in improving performance under conditions of sleep deprivation by reducing feelings of tiredness, mental exhaustion and irritability without exacerbating glucose metabolism and feelings of hunger. PMID- 29582509 TI - The contribution of smokefree outdoor areas in achieving New Zealand's Smokefree 2025 goal. AB - ISSUES ADDRESSED: With the adoption of Smokefree 2025, further commitment from local government to extend smokefree outdoor area policies is becoming increasingly important in the presence of high public support. The aim of this study was to identify local government commitment in the Canterbury/West Coast (CWC) region to the New Zealand Smokefree 2025 goal through provision of smokefree outdoor areas. METHODS: Document analysis of the different stages of council long-term plans (LTPs) was undertaken, including 239 draft LTP documents, 5926 public submissions on these documents and 13 final LTP documents. A comparison between the 2015 final document and the 2012 final document was undertaken. Following this, semi-structured telephone interviews were undertaken with council staff. RESULTS: No council had referred to Smokefree 2025 or smokefree community spaces in any 2015 LTP draft document. Each of the CWC councils received a number of smokefree-related submissions, with the main theme being the extension of current Smokefree Outdoor Area Policy. The final LTP documents showed that 5 councils had included a brief statement about Smokefree 2025. Smokefree issues were mentioned more often in the 2012 LTP compared to the 2015 LTP. CONCLUSIONS: This research highlights a need for more commitment by local government to achieving the Smokefree 2025 goal. So what? There are opportunities for health groups to work with councils to try and enhance their overall commitment to Smokefree 2025 and promote wellbeing. PMID- 29582508 TI - Cell-assembled nanoclusters of MSC-targeting Gd-DOTA-peptide as a T2 contrast agent for MRI cell tracking. AB - A cyclic peptide CC9 that targets cell membrane of mesenchymal stem cells (MSCs) is coupled with Gd-DOTA to yield a Gd-DOTA-CC9 complex as MRI contrast agent. It is used to label human MSCs (hMSCs) via electroporation. Electroporation-labeling of hMSCs with Gd-DOTA-CC9 induces cell-assembly of Gd-DOTA-CC9 nanoclusters in the cytoplasm, significantly promotes cell-labeling efficacy and intracellular retention time of the agent. In vitro MRI of labeled hMSCs exhibits significant signal reduction under T2 -weighted MRI, which can allow long-term tracking of labeled cell transplants in in vivo migration. The labeling strategy is safe in cytotoxicity and differentiation potential. PMID- 29582510 TI - Mental health disclosure amongst clinical psychologists in training: Perfectionism and pragmatism. AB - OBJECTIVES: This study investigated the incidence of lived experience of mental health problems amongst UK-based trainee clinical psychologists and factors associated with anticipated disclosure for trainees both with and without lived experience. METHODS: A web-based survey comprising the Multidimensional Perfectionism Scale, an adapted version of the Perceived Devaluation and Discrimination Scale, and questions about lived experience and anticipated likelihood of disclosure. RESULTS: The survey was completed by 348 trainees across 19 UK training institutions. Sixty-seven percent reported lived experience of a mental health problem. For these trainees, there was no difference in anticipated likelihood of disclosing to different recipient types after controlling for maladaptive perfectionism. However, across all participants, anticipated disclosure was associated with maladaptive perfectionism, temporal proximity, anticipated stigma (past), and recipient type. Anticipated stigma (present) was not associated with anticipated disclosure. CONCLUSIONS: Results support an approach to communicating about mental health disclosure that incorporates responsibility, interdependency, and transparency. Suggestions for further research are discussed. PMID- 29582511 TI - Comparative histochemical analysis of glycoconjugates in the nasal vestibule of camel and sheep. AB - While Corriedale sheep survive in a wide range of climates, which prevents them to specialize for one climatic condition only, dromedary camels strictly adapted to desert areas. This demands more adaptive mechanisms to hot, dry conditions in camels than in sheep. Being the entrance of the nasal cavity, nasal vestibule is subjected to various environmental stressors. A protective way is the lining epithelium which is cornified in camel, but not in sheep. Mucus nasal secretions also play a key role in the protection of underlyings. Additionally, arterio venous anastomosis is present in the lamina propria of the nasal vestibule of camel. In the present paper, sugar residues in the nasal vestibule of camel were analyzed and compared with those of sheep using 14 types of lectins to explore the distribution of glycoconjugates that may help the function of camel nasal vestibule in desert environment. In camel, none of the lectins could label the basal cells of the vestibular epithelium, although the basal cells reacted with six lectins in sheep. In camel, LEL and RCA-120 markedly labeled the luminal surface. WGA, DBA, SBA, and VVA produced marked intensities on the luminal surface in sheep. The mucous glands reacted with six lectins: WGA, s-WGA, VVA, PNA, PHA-E, and PHA-L in camel, while all lectins used except s-WGA and PHA-E reacted in the sheep. In summary, great differences are observed in the glycoconjugate expression between camel and sheep. This suggests that these glycoconjugate are related to camel's tolerance for environmental stressors. PMID- 29582512 TI - Common and distinct neural correlates of self-serving and prosocial dishonesty. AB - People often anticipate certain benefits when making dishonest decisions. In this article, we aim to dissociate the neural-cognitive processes of (1) dishonest decisions that focus on overall benefits of being dishonest (regardless of whether the benefits are self-serving or prosocial) from (2) those that distinguish between self-serving and prosocial benefits. Thirty-one participants had the opportunity to maximize their monetary benefits by voluntarily making dishonest decisions while undergoing functional magnetic resonance imaging (fMRI). In each trial, the monetary benefit of being dishonest was either self serving or prosocial. Behaviorally, we found dissociable patterns of dishonest decisions: some participants were dishonest for overall benefits, while others were primarily dishonest for self-serving (compared with prosocial) benefits. When provided an opportunity to be dishonest for either self-serving or prosocial benefits, participants with a stronger overall tendency to be dishonest had stronger vmPFC activity, as well as stronger functional connectivity between the vmPFC and dlPFC. Furthermore, vmPFC activity was associated with decisions to be dishonest both when the benefits of being dishonest were self-serving and prosocial. Conversely, high self-serving-biased participants had stronger striatum activity and stronger functional connectivity between the striatum and middle-mPFC when they had a chance to be dishonest for self-serving (compared with prosocial) benefits. Altogether, we showed that activity in (and functional connectivity between) regions in the valuation (e.g., vmPFC and Str) and executive control (e.g., dlPFC and mmPFC) systems play a key role in registering the social-related goal of dishonest decisions. PMID- 29582513 TI - Pollen morphology of subfamily Caryophylloideae (Caryophyllaceae) and its taxonomic significance. AB - The Pollen morphology of subfamily Caryophylloideae (Caryophyllaceae) from different phytogeographical region of Pakistan has been evaluated. In this research, 16 species belong to 6 genera of subfamily Caryophylloideae have been studied using light (LM) and scanning electron microscopy (SEM) for both qualitative and quantitative characters. Different palyno-morphological features were observed including; pollen ornamentation, pore ornamentation, echini arrangement, echinidensity, number of pori, size of polar and equatorial diameter, P/E ratio, exine thickness, and size of pore were studied. The palyno morphological characters of subfamily Caryophylloideae have taxonomically significant in identification and delimitation of species. Two pollen types, i.e., subspheroidal (15 species) and prolate (one species Vaccaria hispanica) were observed. Microechinate-punctate and microechinate-perforate pollen ornamentation were examined. Two pollen types of pori, i.e., prominent (5 species) and sunken (11 species) ornamentation have been reported. Three types of echini arrangement have been reported irregular, regular and rather regular, while three type of echinidensity (i.e., medium, dense and sparse) were observed. Pori numbers were found different in different species range from 5 in Silene apetala to 19-35 in Silene vulgaris. Based on different palyno-morphological characters, taxonomic key was develop for quick and accurate identification. The quantitative data were processed using SPSS software for average, minimum, maximum, and standard error. PMID- 29582514 TI - Altered gray matter volume and disrupted functional connectivity of dorsolateral prefrontal cortex in men with heroin dependence. AB - AIM: Chronic heroin use can cause various neuropathological characteristics that may compromise brain function. The present study evaluated the alteration of gray matter volume (GMV) and its resting-state functional connectivity (rsFC) over the dorsolateral prefrontal cortex (DLPFC) among male heroin users. METHODS: Thirty heroin-dependent men undergoing methadone maintenance therapy and 30 educational level- and age-matched male controls were recruited for this study. To assess their GMV and rsFC, the participants were evaluated using spoiled gradient echo and gradient-recalled echo planar imaging sequences with a 3-Tesla General Electric MR scanner under resting state. RESULTS: The heroin-dependent men showed lower GMV over the right DLPFC in comparison with the controls. Further evaluation of the rsFC of the right DLPFC revealed a marked decrease in interhemispheric DLPFC connectivity among those with heroin dependence under control of head movement and GMV of the right DLPFC. CONCLUSION: Although the mechanism remains unclear, the present study shows that chronic heroin use is associated with alteration of morphology as well as rsFC over the right DLPFC. As the DLPFC plays an imperative role in various domains of cognitive function, service providers for heroin users should consider the impacts of possible DLPFC related cognitive deficits on treatment effectiveness. PMID- 29582515 TI - Comparison of changes in the oxygenated hemoglobin level during a 'modified rock paper-scissors task' between healthy subjects and patients with schizophrenia. AB - AIM: The purpose of this study, using single-event-related near-infrared spectroscopy (NIRS), was to examine the psychophysiological and social function assessment of 30 schizophrenic patients during a modified rock-paper-scissors task. METHODS: We set up a screen in front of the subjects, on which pictures of hand-gestures for rock, paper, and scissors were randomly presented. Subjects were asked to give verbal answers under the conditions of win, lose, and draw, respectively. Using the 44-channel NIRS system, we evaluated the maximum amplitude of oxygenated hemoglobin, latency, and the area based on the arithmetic mean of resulting values after the task between 30 outpatients with schizophrenia and 30 healthy subjects, and analyzed the frontal pole area, dorsolateral prefrontal region, and parietal association area as regions of interest (ROI). RESULTS: In schizophrenic patients, oxygenated hemoglobin changes (Deltaoxy-Hb) when losing the task showed a significantly lower level of Deltaoxy-Hb in ROI than controls. In addition, a significant positive correlation was observed between the Global Assessment of Functioning Scale and Deltaoxy-Hb in ROI, and a significant negative correlation was observed between the Negative Syndrome scale of the Positive and Negative Syndrome Scale and Deltaoxy-Hb in ROI. CONCLUSION: From these results, we conclude that Deltaoxy-Hb levels when performing the modified rock-paper-scissors task assessed using NIRS may be a useful psychophysiological marker to evaluate the cognitive and social functions of schizophrenic patients. PMID- 29582516 TI - Long-term tolerability, immunogenicity and efficacy of Nuwiq(r) (human-cl rhFVIII) in children with severe haemophilia A. AB - INTRODUCTION: Nuwiq(r) (human-cl rhFVIII, simoctocog alfa) is a 4th generation recombinant human FVIII, without chemical modification or fusion with any other protein, produced in a human cell line. AIM/METHODS: This study (GENA-13) was an extension of the GENA-03 study in which previously treated children aged 2-12 years with severe haemophilia A received Nuwiq(r) prophylaxis for >=6 months. GENA-13 examined long-term tolerability, immunogenicity and efficacy of Nuwiq(r) prophylaxis in children. RESULTS: Of 59 patients enrolled in GENA-03, 49 continued Nuwiq(r) prophylaxis in GENA-13 for a median (range) of 30.0 (9.5-52.0) months. No patient withdrew due to drug-related adverse events or developed inhibitors. Only 2 of 20 518 infusions were associated with possibly related adverse events (dyspnoea, fever). The estimated annualized bleeding rate (ABR) was 0.67 (95% CI: 0.44, 1.02) for spontaneous and 2.88 (95% CI: 1.86, 4.46) for all bleeds. Younger children (2-5 years) had lower ABRs than children aged 6-12 years. Annualized bleeding rates were reduced in GENA-13 vs GENA-03, especially for spontaneous bleeds in younger children (71% reduction; ABR ratio 0.29 [95% CI: 0.11, 0.74]). Nuwiq(r) efficacy was rated as excellent/good in the treatment of 83.0% of 305 evaluated breakthrough bleeds. Surgical prophylaxis with Nuwiq(r) was rated as excellent for all 17 assessed procedures. CONCLUSION: Long-term treatment with Nuwiq(r) for the prevention of bleeds in children with severe haemophilia A was well tolerated, effective and reduced spontaneous bleeding by up to 70% compared with GENA-03. PMID- 29582517 TI - Effects of early motivational interviewing on post-stroke depressive symptoms: A pilot randomized study of the Good Mood Intervention program. AB - AIMS: The aim of this pilot randomized study was to investigate the feasibility of early motivational interviewing, for reducing mood after acute stroke. BACKGROUND: Depression is a frequent consequence of stroke that can adversely affect recovery. METHODS: DESIGN: Pilot randomized study. Intervention group patients received 3, individual motivational interviewing sessions by nurses or social workers prior to hospital discharge. PARTICIPANTS: Adult patients with acute stroke during 2013 to 2014. BLINDING: Research assistant who collected data was blind to group assignment. OUTCOMES: Data were collected at 3 time points: baseline, 1-month, and 3-month follow-up. Outcome measures (anxiety, depression, quality of life) were analysed by descriptive statistics. RESULTS: Forty-eight patients were enrolled, and 79% retention was achieved at 3 months. Eight participants withdrew (16.7%), and 2 were unable to participate (death: 2.1% and new onset aphasia: 2.1%), leaving 38 participants in the final cohort (Intervention: N = 18, Control: N = 20). Anxiety, depression, and quality of life measures did not alter significantly in the study period. CONCLUSIONS: Carefully designed studies are required to investigate the effectiveness of early motivational interviewing for improving mood after stroke. The therapy can be administered by nurses, but significant resources are required in terms of training and fidelity. PMID- 29582518 TI - Long-term safety and effectiveness of brexpiprazole in Japanese patients with schizophrenia: A 52-week, open-label study. AB - AIM: This study assessed the long-term safety, tolerability, and maintenance of the therapeutic effect of brexpiprazole in Japanese patients with schizophrenia. METHODS: This 52-week, open-label, flexible-dose (1-4 mg/day) study included patients with schizophrenia who continued treatment from a short-term randomized placebo-controlled fixed-dose (1, 2, or 4 mg/day) trial and de novo patients who switched from other antipsychotics. RESULTS: A total of 282 patients (184 de novo and 98 rolled over from short-term trial) entered the 52-week treatment with brexpiprazole, and 150 (53.2%) patients completed the week-52 assessment. Treatment-emergent adverse events (TEAE) were experienced by 235/281 patients (83.6%), and TEAE reported by >=10% of all patients were nasopharyngitis (23.1%) and worsening of schizophrenia (22.4%). During the study, most of the TEAE were mild or moderate in severity, and there were no deaths, and no clinically meaningful mean changes in laboratory values, vital signs, or electrocardiogram parameters. Mean scores for the Positive and Negative Syndrome Scale total and Clinical Global Impression-Severity remained stable until week 52. CONCLUSION: Brexpiprazole was generally safe and well tolerated and maintained therapeutic effects in the long-term treatment of Japanese patients with schizophrenia. PMID- 29582519 TI - Peripheral neuropathy in Tangier disease: A literature review and assessment. AB - Tangier disease (TD) (OMIM#205400) is a rare cause of inherited metabolic neuropathies characterized by marked deficiency of high-density lipoproteins and accumulation of cholesterol esters in various tissue resulting from reverse cholesterol transport deficiency. We report a case of a patient with TD with multifocal demyelinating neuropathy with conduction block who presents with winging scapula, tongue, and asymmetric extremity weakness. We also present a review of all studies published from 1960 to 2017 regarding peripheral neuropathy in TD. Our search identified 54 patients with TD with peripheral neuropathy. Syringomyelia-like neuropathy subtype (52.4%) was more frequent than multifocal sensorial and motor neuropathy subtype (26.2%), focal neuropathy subtype (19.1%), and distal symmetric polyneuropathy subtype (2.4%). Splenomegaly was the most common (40.7%) clinical manifestation in these patients. The pattern of electrodiagnostic abnormalities are: (1) demyelinating abnormalities were more predominant in the upper extremities than in the lower extremities and (2) slowing of motor nerve conduction was more prominent in the intermediate segment than in distal nerve segments. The sural-sparing pattern was present in 34.6% and conduction block was present in 11.5% of the patients. Our literature review and our case showed the clinical spectrum of TD neuropathy is quite wide and that it should be considered in the differential diagnosis of non-uniform demyelinating neuropathies. PMID- 29582520 TI - Pediatric endocrine society survey of diabetes practices in the United States: What is the current state? AB - BACKGROUND: The Practice Management Committee (PMC) of the Pediatric Endocrine Society (PES) conducted a survey of its membership in February/March, 2016 to assess the current state of pediatric diabetes care delivery across multiple practice types in the United States. METHODS: The PES distributed an anonymous electronic survey (Survey Monkey) via email to its membership and requested that only one survey be completed for each practice. RESULTS: Ninety-three unique entries from the US were entered into analysis. Care is predominantly delivered by multidisciplinary teams, based at academic institutions (65.6%), with >85% of the provider types being physicians. Each 1.0 full time equivalent certified diabetes educators serves on average 367 diabetic youth. Fee-for-service remains the standard method of reimbursement with 57% of practices reporting financial loss. Survey respondents identified under-reimbursement as a major barrier to improving patient outcomes and lack of behavioral health (BH) providers as a key gap in services provided. CONCLUSIONS: Our survey reveals wide variation in all aspects of pediatric diabetes care delivery in the United States. Pediatric Endocrinologists responding to the survey identified a lack of resources and the current fee for service payment model as a major impediment to practice and the lack of integrated BH staff as a key gap in service. The respondents strongly support its organizations' involvement in the dissemination of standards for care delivery and advocacy for a national payment model aligned with chronic diabetes care in the context of our emerging value-based healthcare system. PMID- 29582522 TI - Education on invasive mechanical ventilation involving intensive care nurses: a systematic review. AB - BACKGROUND: Intensive care unit nurses are critical for managing mechanical ventilation. Continuing education is essential in building and maintaining nurses' knowledge and skills, potentially improving patient outcomes. AIMS: The aim of this study was to determine whether continuing education programmes on invasive mechanical ventilation involving intensive care unit nurses are effective in improving patient outcomes. METHODS: Five electronic databases were searched from 2001 to 2016 using keywords such as mechanical ventilation, nursing and education. Inclusion criteria were invasive mechanical ventilation continuing education programmes that involved nurses and measured patient outcomes. Primary outcomes were intensive care unit mortality and in-hospital mortality. Secondary outcomes included hospital and intensive care unit length of stay, length of intubation, failed weaning trials, re-intubation incidence, ventilation associated pneumonia rate and lung-protective ventilator strategies. Studies were excluded if they excluded nurses, patients were ventilated for less than 24 h, the education content focused on protocol implementation or oral care exclusively or the outcomes were participant satisfaction. Quality was assessed by two reviewers using an education intervention critical appraisal worksheet and a risk of bias assessment tool. Data were extracted independently by two reviewers and analysed narratively due to heterogeneity. RESULTS: Twelve studies met the inclusion criteria for full review: 11 pre- and post-intervention observational and 1 quasi-experimental design. Studies reported statistically significant reductions in hospital length of stay, length of intubation, ventilator associated pneumonia rates, failed weaning trials and improvements in lung protective ventilation compliance. Non-statistically significant results were reported for in-hospital and intensive care unit mortality, re-intubation and intensive care unit length of stay. CONCLUSION: Limited evidence of the effectiveness of continuing education programmes on mechanical ventilation involving nurses in improving patient outcomes exists. Comprehensive continuing education is required. RELEVANCE TO CLINICAL PRACTICE: Well-designed trials are required to confirm that comprehensive continuing education involving intensive care nurses about mechanical ventilation improves patient outcomes. PMID- 29582521 TI - Identified OAS3 gene variants associated with coexistence of HBsAg and anti-HBs in chronic HBV infection. AB - The underlying mechanism of coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antigen antibody (anti-HBs) is still controversial. To identify the host genetic factors related to this unusual clinical phenomenon, a two-stage study was conducted in the Chinese Han population. In the first stage, we performed a case-control (1:1) age- and gender-matched study of 101 cases with concurrent HBsAg and anti-HBs and 102 controls with negative HBsAg and positive anti-HBs using whole exome sequencing. In the second validation stage, we directly sequence the 16 exons on the OAS3 gene in two dependent cohorts of 48 cases and 200 controls. Although, in the first stage, a genome-wide association study of 58,563 polymorphism variants in 101 cases and 102 controls found no significant loci (P-value <= .05/58563), and neither locus achieved a conservative genome-wide significance threshold (P-value <= 5e-08), gene-based burden analysis showed that OAS3 gene rare variants were associated with the coexistence of HBsAg and anti-HBs. (P-value = 4.127e-06 <= 0.05/6994). A total of 16 rare variants were screened out from 21 cases and 3 controls. In the second validation stage, one case with a stop-gained rare variant was identified. Fisher's exact test of all 149 cases and 302 controls showed that the rare coding sequence mutations were more frequent in cases vs controls (P-value = 7.299e-09, OR = 17.27, 95% CI [5.01-58.72]). Protein-coding rare variations on the OAS3 gene are associated with the coexistence of HBsAg and anti-HBs in patients with chronic HBV infection in Chinese Han population. PMID- 29582523 TI - UV Resonance Raman Study of Apoptosis, Platinum-Based Drugs, and Human Cell Lines. AB - As a noninvasive molecular analysis technique, ultraviolet resonance Raman (UVRR) spectroscopy represents a label-free method suitable for characterizing biomolecules. Using UVRR spectroscopy, we collected spectral fingerprints of UV absorbing cellular components, including proteins, nucleic acids, and unsaturated lipids. This knowledge was used to guide the assignment of spectra derived from intact human cell lines (i. e., HSC-3 and HaCaT) and from the apoptotic events induced by cisplatin. Notably, a jet-flow system was employed to generate flowing cell suspensions during UVRR measurements, minimizing UV-induced damage. A spectral marker is established based on the ratio of Raman intensities at 1488 and 1655 cm-1 ; this ratio correlates to the level of cell death due to apoptosis. Collectively, this work demonstrates that UVRR spectroscopy is a sensitive and informative probe of cellular physiology and molecular composition. The molecular insight obtained from UVRR measurements can be used to improve understanding of therapeutic treatment and to guide drug development and the choice of therapeutic agents. PMID- 29582524 TI - Selective Activation of a Prodrug by Thioredoxin Reductase Providing a Strategy to Target Cancer Cells. AB - Elevated reactive oxygen species and antioxidant defense systems have been recognized as one of the hallmarks of cancer cells. As a major regulator of the cellular redox homeostasis, the selenoprotein thioredoxin reductase (TrxR) is increasingly considered as a promising target for anticancer drug development. The current approach to inhibit TrxR predominantly relies on the modification of the selenocysteine residue in the C-terminal active site of the enzyme, in which it is hard to avoid the off-target effects. By conjugating the anticancer drug gemcitabine with a 1,2-dithiolane scaffold, an unprecedented prodrug strategy is disclosed that achieves a specific release of gemcitabine by TrxR in cells. As overexpression of TrxR is frequently found in different types of tumors, the TrxR dependent prodrugs are promising for further development as cancer chemotherapeutic agents. PMID- 29582525 TI - Clinical experience with moroctocog alfa (AF-CC) in younger paediatric patients with severe haemophilia A: Two open-label studies. AB - INTRODUCTION: The pharmacokinetics (PK), efficacy and safety of moroctocog alfa (AF-CC) have been demonstrated in haemophilia A patients aged >=6 years. AIM: These studies aimed to further describe moroctocog alfa (AF-CC) experience in paediatric patients (<12 years) with severe haemophilia A (FVIII:C < 1%). METHODS: Two prospective, open-label studies enrolled patients aged <12 years: one study with 37 previously treated patients (PTPs) and another with 23 previously untreated patients (PUPs). All patients initially received 50 IU/kg of moroctocog alfa (AF-CC) to evaluate either recovery alone, or with other PK parameters (6 to <12 years) before continuing treatment for 100 exposure days (EDs) or 24 months. RESULTS: At baseline, mean (+/-SD) recovery ranged between 1.32 +/- 0.65 (PUPs aged <2 years) and 2.13 +/- 0.82 (PTPs aged 6 to <12 years). The mean (+/-SD) half-life was 9.12 +/- 1.94 hours in PTPs aged 6 to <12 years. No new safety signals were detected in either study, 2 transient lower titre inhibitors occurred in PTPs while 8 inhibitors (3 low and 5 high titre) were detected in PUPs. Most bleeding episodes resolved with one infusion (94% [893/954]). The annualised bleeding rate (ABR) in the PTP study was 27.5 and 4.2 for patients reporting an on-demand and routine prophylaxis regimen at baseline, respectively. In the PUP study, the overall ABR was 5.9. CONCLUSION: Moroctocog alfa (AF-CC) had expected PK findings (lower recovery in young children compared with older children) along with being safe and efficacious in a population of young severe haemophilia A patients. PMID- 29582526 TI - Whole-exome sequencing reveals a novel missense mutation in the MARS gene related to a rare Charcot-Marie-Tooth neuropathy type 2U. AB - Charcot-Marie-Tooth (CMT) is a heterogeneous group of progressive disorders, characterized by chronic motor and sensory polyneuropathy. This hereditary disorder is related to numerous genes and varying inheritance patterns. Thus, many patients do not reach a final genetic diagnosis. We describe a 13-year-old girl presenting with progressive bilateral leg weakness and gait instability. Extensive laboratory studies and spinal magnetic resonance imaging scan were normal. Nerve conduction studies revealed severe lower limb peripheral neuropathy with prominent demyelinative component. Following presumptive diagnosis of chronic inflammatory demyelinating polyneuropathy, the patient received treatment with steroids and intravenous immunoglobulins courses for several months, with no apparent improvement. Whole-exome sequencing revealed a novel heterozygous c.2209C>T (p.Arg737Trp) mutation in the MARS gene (OMIM 156560). This gene has recently been related to CMT type 2U. In-silico prediction programs classified this mutation as a probable cause for protein malfunction. Allele frequency data reported this variant in 0.003% of representative Caucasian population. Family segregation analysis study revealed that the patient had inherited the variant from her 60-years old mother, reported as healthy. Neurologic examination of the mother demonstrated decreased tendon reflexes, while nerve conduction studies were consistent with demyelinative and axonal sensory-motor polyneuropathy. Our report highlights the importance of next-generation sequencing approach to facilitate the proper molecular diagnosis of highly heterogeneous neurologic disorders. Amongst other numerous benefits, this approach might prevent unnecessary diagnostic testing and potentially harmful medical treatment. PMID- 29582527 TI - Rab11 mediates selective recycling and endocytic trafficking in Trypanosoma brucei. AB - Trypanosoma brucei possesses a streamlined secretory system that guarantees efficient delivery to the cell surface of the critical glycosyl phosphatidylinositol (GPI)-anchored virulence factors, variant surface glycoprotein (VSG) and transferrin receptor (TfR). Both are thought to be constitutively endocytosed and returned to the flagellar pocket via TbRab11+ recycling endosomes. We use conditional knockdown with established reporters to investigate the role of TbRab11 in specific endomembrane trafficking pathways in bloodstream trypanosomes. TbRab11 is essential. Ablation has a modest negative effect on general endocytosis, but does not affect turnover, steady state levels or surface localization of TfR. Nor are biosynthetic delivery to the cell surface and recycling of VSG affected. TbRab11 depletion also causes increased shedding of VSG into the media by formation of nanotubes and extracellular vesicles. In contrast to GPI-anchored cargo, TbRab11 depletion reduces recycling of the transmembrane invariant surface protein, ISG65, leading to increased lysosomal turnover. Thus, TbRab11 plays a critical role in recycling of transmembrane, but not GPI-anchored surface proteins. We proposed a two-step model for VSG turnover involving release of VSG-containing vesicles followed by GPI hydrolysis. Collectively, our results indicate a critical role of TbRab11 in the homeostatic maintenance of the secretory/endocytic system of bloodstream T. brucei. PMID- 29582529 TI - How can "Super Corals" facilitate global coral reef survival under rapid environmental and climatic change? AB - Coral reefs are in a state of rapid global decline via environmental and climate change, and efforts have intensified to identify or engineer coral populations with increased resilience. Concurrent with these efforts has been increasing use of the popularized term "Super Coral" in both popular media and scientific literature without a unifying definition. However, how this subjective term is currently applied has the potential to mislead inference over factors contributing to coral survivorship, and the future trajectory of coral reef form and functioning. Here, we discuss that the information required to support a single definition does not exist, and in fact may never be appropriate, i.e. "How Super is Super"? Instead, we advocate caution of this term, and suggest a workflow that enables contextualization and clarification of superiority to ensure that inferred or asserted survivorship is appropriate into future reef projections. This is crucial to robustly unlock how "Super Corals" can be integrated into the suite of management options required to facilitate coral survival under rapid environmental and climate change. PMID- 29582528 TI - Efficient cell delivery mediated by lipid-specific endosomal escape of supercharged branched peptides. AB - Various densely charged polycationic species, whether of biological or synthetic origin, can penetrate human cells, albeit with variable efficiencies. The molecular underpinnings involved in such transport remain unclear. Herein, we assemble 1, 2 or 3 copies of the HIV peptide TAT on a synthetic scaffold to generate branched cell-permeable prototypes with increasing charge density. We establish that increasing TAT copies dramatically increases the cell penetration efficiency of the peptides while simultaneously enabling the efficient cytosolic delivery of macromolecular cargos. Cellular entry involves the leaky fusion of late endosomal membranes enriched with the anionic lipid BMP. Derivatives with multiple TAT branches induce the leakage of BMP-containing lipid bilayers, liposomal flocculation, fusion and an increase in lamellarity. In contrast, while the monomeric counterpart 1TAT binds to the same extent and causes liposomal flocculation, 1TAT does not cause leakage, induce fusion or a significant increase in lamellarity. Overall, these results indicate that an increase in charge density of these branched structures leads to the emergence of lipid specific membrane-disrupting and cell-penetrating activities. PMID- 29582530 TI - Safety and utility of surveillance biopsies in pediatric kidney transplant patients. AB - There is currently no way to diagnose a rejection before a change in serum creatinine. This had led some to start doing SB, but little data exist on the utility and safety of SB in pediatric patients. There is also little known on practice patterns of pediatric nephrologists. A retrospective review of pediatric kidney transplant SB between January 2013 and January 2017 at a single center was performed. A survey went to the PedNeph email list. There were 47 SB; 15 at 6 months, 12 at 1 year, 13 at 2 years, and 7 at 3 years. There were 3 minor (1 gross hematuria and 2 hematomas) and no major complications. On 6-month SB, 1 had SC 1A ACR (6.7%) with no BR ACR. On the 12-month SB, there were 5 with SCBR ACR (41.7%) and 1 with SC AMR (8.3%). On the 2-year SB, there were 4 that had SCBR ACR (30.8%), and 1 with SC AMR (7.7%). On the 3-year SB, 1 had chronic transplant glomerulitis (14.3%). The survey showed that 34.3% of pediatric nephrologists perform SB. SB can be performed safely. By early identification of histological lesions, SB gives us an opportunity for individualized immunosuppressive regimens that may prevent chronic allograft dysfunction and improve long-term graft outcome.

AB - BACKGROUND: A paucity of reports in the literature exists concerning the co existence between autism spectrum disorder (ASD) and type 1 diabetes (T1D). OBJECTIVE: To compare clinical characteristics, diabetes management and metabolic control in youth with T1D and ASD (T1D-ASD) with youth without ASD (T1D-non ASD). METHODS: Using the German/Austrian diabetes patient follow-up registry, this study analyzed aggregated data from the last available year of observation for each patient with T1D, ages 1-20 with consistent data on insulin regimen and glycated hemoglobin (A1C), between January, 2005 and March, 2017. RESULTS: From 61 749 patients, 150 (0.24%) were identified as T1D-ASD. Non-adjusted comparisons showed similar results for mean age at onset and duration of diabetes, but not for gender (male: T1D-ASD: 85.3%; T1D-non ASD: 52.8%; P < .001). Unadjusted comparisons showed no difference for severe hypoglycemia, diabetic ketoacidosis, insulin doses, insulin pump therapy, and body mass index. A statistical difference was observed for A1C (P-value .01) and in the number of blood glucose (SMBG) tests/day (median [interquartile range]: T1D-ASD 6.0 [4.4-7.0]; T1D-non ASD 5.0 [4.4-7.0]; P-value < .001). After adjusting for age, gender, duration of diabetes, and year of observation, only SMBG remained significant (P-value .003). T1D-ASD used psycho-stimulants (15.3% vs 2.2%; P-value < .001), antipsychotics (10.7% vs 0.6%; P-value < .001), and antidepressive medications (3.6% vs 0.7%; P value < .001) more frequently. CONCLUSION: Metabolic control was similar in the T1D-ASD group compared to T1D-non ASD despite their comorbidity. Awareness of ASD remains important in T1D treatment, as both conditions require long-term multi disciplinary medical follow-up for optimal outcomes. PMID- 29582532 TI - Extracellular HtrA serine proteases: An emerging new strategy in bacterial pathogenesis. AB - The HtrA family of chaperones and serine proteases is important for regulating stress responses and controlling protein quality in the periplasm of bacteria. HtrA is also associated with infectious diseases since inactivation of htrA genes results in significantly reduced virulence properties by various bacterial pathogens. These virulence features of HtrA can be attributed to reduced fitness of the bacteria, higher susceptibility to environmental stress and/or diminished secretion of virulence factors. In some Gram-negative and Gram-positive pathogens, HtrA itself can be exposed to the extracellular environment promoting bacterial colonisation and invasion of host tissues. Most of our knowledge on the function of exported HtrAs stems from research on Helicobacter pylori, Campylobacter jejuni, Borrelia burgdorferi, Bacillus anthracis, and Chlamydia species. Here, we discuss recent progress showing that extracellular HtrAs are able to cleave cell-to-cell junction factors including E-cadherin, occludin, and claudin-8, as well as extracellular matrix proteins such as fibronectin, aggrecan, and proteoglycans, disrupting the epithelial barrier and producing substantial host cell damage. We propose that the export of HtrAs is a newly discovered strategy, also applied by additional bacterial pathogens. Consequently, exported HtrA proteases represent highly attractive targets for antibacterial treatment by inhibiting their proteolytic activity or application in vaccine development.

AB - AIM: We aimed to evaluate whether potentially inappropriate medications (PIMs) increase the risk for adverse clinical outcomes including falls, emergency department (ED) visits and unplanned hospitalizations in older Japanese patients with chronic diseases, comparing the difference between patients with and without polypharmacy. METHODS: A prospective observational cohort study was carried out in a Japanese outpatient primary care clinic. Baseline data was collected from January to March 2016. A total of 740 patients aged >=65 years with chronic diseases were enrolled and were followed up at 1 year; falls, ED visits and unplanned hospitalizations were recorded. A questionnaire and review of the patients' medical records were used to collect information regarding sociodemographic status, comorbidities and medication prescriptions. PIMs were defined using the Screening Tool of Older Person's Prescriptions criteria version 2. Using logistic regression analysis, the incidence of falls, and ED visits and hospitalizations were compared between patients with and without PIMs, stratifying by number of prescriptions: those with five or more prescriptions and those with fewer than five prescriptions. RESULTS: PIMs were identified in 32.3% of enrolled patients. After stratification by number of prescriptions, PIMs were significantly associated with falls in the group with polypharmacy (OR 2.03, 95% CI 1.11-3.69). This association was not seen in the group without polypharmacy. PIMs were not associated with ED visits or hospitalizations at the 1-year follow up upon multivariate analysis. CONCLUSIONS: The combination of PIMs and polypharmacy might increase the risk of falls, therefore clinicians need to pay attention to both PIMs and polypharmacy.

PMID- 29582534 TI - Impact of frailty on chronic pain, activities of daily living and physical activity in community-dwelling older adults: A cross-sectional study. AB - AIM: The present cross-sectional study investigated the relationship between frailty and chronic pain, activities of daily living (ADL), and physical activity in community-dwelling older adults. METHODS: Participants were 379 older adults who attended community-based exercise classes. Outcome measures were frailty as determined by the Kihon Checklist, full pain assessment (including the sensory, emotional and cognitive aspects of pain), ADL and physical activity. These outcomes were evaluated using validated tests and instruments. Assessments were carried out before beginning the exercise classes. Outcome measures were compared for participants with and without frailty. Frailty was defined as a total Kihon Checklist score >=7, and chronic pain as the presence of related symptoms within the past month that had continued for at least 6 months and corresponded with a numerical rating scale score of at >=5 at the site of maximum pain. RESULTS: In total, 134 (35.4%) participants met the frailty criteria; 60.4% of this group had chronic pain. The frail group had significantly worse scores for the sensory, emotional and cognitive aspects of pain, ADL and physical activity than the non frail group (P < 0.05). Logistic regression analysis adjusted for age and sex showed the sensory and emotional aspects of pain were associated with frailty. CONCLUSIONS: For community-dwelling older adults with frailty, chronic pain can negatively influence sensory, emotional and cognitive aspects of pain, leading to a decline in ADL and lower physical activity. Full pain assessment focused on sensory and emotional aspects of pain is important to identify frailty among older adults. Geriatr Gerontol Int 2018; 18: 1079-1084.

AB - West Nile virus (WNV) is a single-stranded, positive sense RNA virus of the family Flaviviridae and is a significant pathogen of global medical importance. Flavivirus replication is known to be exclusively cytoplasmic, but we show here for the first time that access to the nucleus of the WNV strain Kunjin (WNVKUN ) RNA-dependent RNA polymerase (protein NS5) is central to WNVKUN virus production. We show that treatment of cells with the specific nuclear export inhibitor leptomycin B (LMB) results in increased NS5 nuclear accumulation in WNVKUN infected cells and NS5-transfected cells, indicative of nucleocytoplasmic shuttling under normal conditions. We used site-directed mutagenesis to identify the nuclear localisation sequence (NLS) responsible for WNVKUN NS5 nuclear targeting, observing that mutation of this NLS resulted in exclusively cytoplasmic accumulation of NS5 even in the presence of leptomycin B. Introduction of NS5 NLS mutations into FLSDX, an infectious clone of WNVKUN , resulted in lethality, suggesting that the ability of NS5 to traffic into the nucleus in integral to WNVKUN replication. This study thus shows for the first time that NLS-dependent trafficking into the nucleus during infection of WNVKUN NS5 is critical for viral replication. Excitingly, specific inhibitors of NS5 nuclear import reduce WNVKUN virus production, proving the principle that inhibition of WNVKUN NS5 nuclear import is a viable therapeutic avenue for antiviral drug development in the future. PMID- 29582536 TI - Comparison of body composition and physical and cognitive function between older Japanese adults with no diabetes, prediabetes and diabetes: A cross-sectional study in community-dwelling Japanese older people. AB - AIM: Diabetes is associated with not only cardiovascular and cerebrovascular disease, but also reductions in physical and cognitive function. The purpose of the present study was to determine whether muscle strength, walking ability and balance declined in Japanese community-dwelling older adults with diabetes or prediabetes. METHODS: We analyzed data from comprehensive health checkups carried out for 1689 individuals (710 men, 979 women; mean age 71.4 +/- 5.6 years) between 2011 and 2016. Participants were divided into three groups: no diabetes (non-history of diabetes and glycated hemoglobin level <5.7%), prediabetes (non history of diabetes, but glycated hemoglobin level was 5.7-6.4%) and diabetes (history of diabetes or glycated hemoglobin level >6.4%). Physical and cognitive function were compared between groups after adjusting for covariates. RESULTS: Participants with diabetes showed higher levels of obesity, comorbidity, gonarthrosis, and body fat, and lower levels of physical function relative to those observed in participants with prediabetes or no diabetes. After adjusting covariates, participants with diabetes showed significantly lower grip strength (P < 0.010), slower walking speed (P < 0.005), longer Timed Up and Go test time (P < 0.007) and less time spent standing on one foot (P < 0.001) relative to those with no diabetes, but not those with prediabetes. CONCLUSIONS: Significant functional decline was observed in community-dwelling older adults with diabetes, but not in those with prediabetes. Prevention of the progression of prediabetes to diabetes is important in avoiding reductions in physical function. Geriatr Gerontol Int 2018; 18: 1031-1037. PMID- 29582537 TI - Prognostic value of tumour regression grade in locally advanced rectal cancer: a systematic review and meta-analysis. AB - AIM: The current standard of care for locally advanced rectal cancer involves neoadjuvant chemoradiotherapy (CRT) followed by total mesorectal excision. There is a spectrum of response to neoadjuvant therapy; however, the prognostic value of tumour regression grade (TRG) in predicting disease-free survival (DFS) or overall survival (OS) is inconsistent in the literature. METHOD: This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was undertaken using Ovid MEDLINE, Embase and Google Scholar. Inclusion criteria were Stage II and III locally advanced rectal cancer treated with long-course CRT followed by radical surgery. The aim of the meta-analysis was to assess the prognostic implication of each TRG for rectal cancer following neoadjuvant CRT. Long-term prognosis was assessed. The main outcome measures were DFS and OS. A random effects model was performed to pool the hazard ratio (HR) from all included studies. RESULTS: There were 4875 patients from 17 studies, with 775 (15.9%) attaining a pathological complete response (pCR) and 719 (29.9%) with no response. A significant association with OS was identified from a pooled-estimated HR for pCR (HR = 0.47, P = 0.002) and nonresponding tumours (HR = 2.97; P < 0.001). Previously known tumour characteristics, such as ypN, lymphovascular invasion and perineural invasion, were also significantly associated with DFS and OS, with estimated pooled HRs of 2.2, 1.4 and 2.3, respectively. CONCLUSION: In conclusion, the degree of TRG was of prognostic value in predicting long-term outcomes. The current challenge is the development of a high-validity tests to predict pCR. PMID- 29582538 TI - Mobile phone applications and self-management of diabetes: A systematic review with meta-analysis, meta-regression of 21 randomized trials and GRADE. AB - We conducted a systematic review with meta-analysis of randomized controlled trials that evaluated the effect of diabetes mobile phone applications. A total of 1550 participants from 21 studies were included. For type 1 diabetes, a significant 0.49% reduction in HbA1c was seen (95% CI, 0.04-0.94; I2 = 84%), with unexplained heterogeneity and a low GRADE of evidence. For type 2 diabetes, using diabetes apps was associated with a mean reduction of 0.57% (95% CI, 0.32 0.82; I2 = 77%). The results had severe heterogeneity that was explained by the frequency of HCP feedback. In studies with no HCP feedback, low frequency and high frequency HCP feedback, the mean reduction is 0.24% (95% CI, 0.02-0.49; I2 = 0%), 0.33% (95% CI, 0.07-0.59; I2 = 47%) and 1.12% (95% CI, 0.91-1.32; I2 = 0%), respectively, with a high GRADE of evidence. There is evidence that diabetes apps improve glycaemic control in type 1 diabetes patients. A reduction of 0.57% in HbA1c was found in type 2 diabetes patients. However, HCP functionality is important to achieve clinical effectiveness. Future studies are needed to explore the cost-effectiveness of diabetes apps and the optimal intensity of HCP feedback.

AB - AIM: Although several risk factors contribute to the development of sarcopenia, whether preclinical atherosclerosis contributes to the risk of sarcopenia is not established. The present cross-sectional study aimed to investigate if there is an association between preclinical atherosclerosis and muscle strength among two ethnic populations. METHODS: Participants included individuals aged >=40 years and enrolled in the third follow-up examination of the Andhra Pradesh Children and Parents Study, India, and in the baseline assessments of the Nagasaki Islands Study, Japan. Preclinical atherosclerosis was evaluated by carotid intima-media thickness, brachial-ankle pulse wave velocity, cardio-ankle vascular index. The association of carotid intima-media thickness and pulse wave velocity/cardio ankle vascular index with handgrip strength (HGS) was analyzed separately in the sexes and for hypertensive status from the two cohorts using a multivariable linear regression model. RESULTS: Data on a total of 1501 participants in India and 3136 participants in Japan were analyzed. Carotid intima-media thickness was negatively associated with HGS in non-hypertensive Indian men (B coefficient = 5.38, P = 0.036). Arterial stiffness was also associated with HGS in non hypertensive Indian men (B = -0.97, P = 0.001), but not in hypertensive Indian men. Same as Indian men, we found the significant associations between arterial stiffness and HGS in non-hypertensive women in both India and Japan (B = -0.44, P = 0.020, B = -0.63, P = 0.016, respectively), but not in hypertensive women. CONCLUSIONS: The negative association between preclinical atherosclerosis and HGS was dominantly found in non-hypertensive participants. Geriatr Gerontol Int 2018; 18: 1071-1078. PMID- 29582541 TI - Relationship of muscle cramps to quality of life and sleep disturbance in patients with chronic liver diseases: A nationwide study. AB - BACKGROUND & AIMS: Although muscle cramps frequently occur in patients with cirrhosis, the importance of muscle cramps remains unclear. The aims of this study were to investigate the relationship of muscle cramps with quality of life (QOL) and sleep disturbance. In addition, this multi-institutional collaborative study in Japan investigated factors associated with muscle cramps in patients with cirrhosis. METHODS: A total of 1788 patients with chronic liver diseases including both non-cirrhosis and cirrhosis completed a questionnaire survey investigating: (i) frequency of muscle cramps, (ii) relationship of muscle cramps to poor QOL and sleep disturbance, (iii) characteristics of patients who require therapeutic intervention and (iv) characteristics of patients prone to experiencing muscle cramps. RESULTS: This study revealed that 51.8% of patients with cirrhosis have experienced muscle cramps. People who experienced muscle cramps were more likely to have reduced QOL and sleep disturbance if muscle cramps had (i) high frequency (occurring daily to a few times per week, P < .01); (ii) long duration (between a few minutes and a few hours, P < .01) and (iii) intense severity (visual analogue scale >=4, P < .01). Age, female sex, positive results for hepatitis C virus, low serum albumin concentration, and cirrhosis were independent factors related to the severity of muscle cramps. CONCLUSION: Muscle cramps occurred with great frequency and were associated with various factors such as age, sex, hepatitis C virus and liver function. Many patients experience poor QOL (26.3%) due to muscle cramps, and therapeutic interventions are therefore needed. PMID- 29582542 TI - Observational cohort study of outcomes in patients admitted to the intensive care unit for acute exacerbation of chronic obstructive pulmonary disease. AB - BACKGROUND: Patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are often referred to the intensive care unit (ICU) for non invasive respiratory support. AIMS: To describe the characteristics of patients with AECOPD admitted to ICU focusing on the performance of ICU prognostic systems, decisions to limit medical therapy and mortality outcomes. METHODS: Retrospective review of patients admitted between 2009 and 2016, separately in patients with active treatment and limitation or withdrawal of medical therapy. ICU acuity scores, blood gas analyses and ICU, in-hospital and 1-year mortality were analysed using descriptive statistics and logistic regression. RESULTS: A total of 403 patients was studied with an overall ICU mortality of 6.4%. The predicted risk of death in hospital using ICU scoring systems was 19% compared to the observed mortality of 15%. One-year mortality was 34%. Patients with limitation of medical therapy represented 32% of the total cohort and had higher mortality in ICU (13%), in hospital (30%) and at 1-year follow up (53%). Withdrawal of life-sustaining therapy occurred in 4% of patients who all died in ICU. Decreased arterial oxygenation and bicarbonate concentration as well as increased arterial carbon dioxide levels were overall associated with an increased likelihood of in-hospital mortality but no independent predictors of 1 year mortality were identified. CONCLUSION: In patients admitted to ICU for AECOPD, limitations of medical therapy are frequent and associated with significant mortality. Involving palliative care in addition to respiratory physicians and intensivists in the management of AECOPD patients admitted to ICU needs to be explored further. PMID- 29582543 TI - Application of the Nexo method in a general dental practice in the Netherlands: 6 year results of a RCT. AB - OBJECTIVES: The aim of this study was to establish the effect of a non-operative caries treatment programme (the Nexo method) in a general dental practice on dental caries, oral hygiene and self-reported motivational factors for a 6-year period. METHODS: A randomized clinical controlled trial study on caries preventive measures in 6- to 12-year-old children was performed among 3 groups of children: (i) care as usual (dental check-ups twice a year, accompanied by a professional fluoride application and the placement of occlusal sealants on a routine basis) (CONTROL); (ii) care as usual plus 2 extra professional fluoride applications (IPFA); or (iii) a non-operative caries treatment programme based on the Nexo method in which recall interval and caries-preventive measures were individualized based on caries activity, eruption stage and motivation of the parent (NOCTP). RESULTS: A total of 106 12-year-old children of the initial 230 6 year-olds completed the full-length study. Children in the NOCTP group developed 0.67 decayed, missing or filled surfaces (DMFS). This value was 0.86 in the IPFA group and 1.02 in control group. The level of oral hygiene was most favourable in the NOCTP group (OHI-s score 0.61 vs 0.87 [IPFA] and 0.70 [control]). Differences were not statistically significant. CONCLUSION: Children who followed the NOCTP programme in this general dental practice did not develop significantly fewer new caries lesions compared with children in the IPFA group or the control group after 6 years. However, the differences identified after the first 3 years of the trial remained apparent. PMID- 29582544 TI - Reversibility of platelet P2Y12 inhibition by platelet supplementation: ex vivo and in vitro comparisons of prasugrel, clopidogrel and ticagrelor. AB - : Essentials Successful outcome of platelet transfusion depends on specific antiplatelet therapy in use. We assessed if ticagrelor, clopidogrel or prasugrel impacts on donor platelet activity ex vivo. Ticagrelor and/or its active metabolite in plasma or bound to platelets can inhibit donor platelets. This might compromise the effectiveness of platelet transfusion therapy. SUMMARY: Background Platelet transfusion is the conventional approach to restore platelet function during acute bleeds or surgery, but successful outcome depends on the specific antiplatelet therapy. Notably ticagrelor is associated with inadequate recovery of platelet function after platelet transfusion. We examined whether plasma and/or platelets from ticagrelor-treated patients influence donor platelet function, in comparison with clopidogrel and prasugrel. Methods Platelet transfusion was mimicked ex vivo by mixing naive donor platelet-rich plasma (PRP) or gel-filtered platelets (GFP) in defined proportions with PRP, plasma or GFP from cardiovascular patients receiving standard care including medication with prasugrel, clopidogrel or ticagrelor (n = 20 each). Blood was taken 4 h after the previous dose. HLA2/HLA28 haplotyping let us distinguish net (all platelet) and individual patient/donor platelet reactivity in mixtures of patient/donor platelets, measured by flow cytometry analysis of ADP-induced fibrinogen binding and CD62P expression. Results ADP responsiveness of donor platelets was dramatically reduced by even low (10%) concentrations of PRP or plasma from ticagrelor-treated patients. Clopidogrel and prasugrel were associated with more modest donor platelet inhibition. GFP from ticagrelor-treated patients but not patients receiving clopidogrel or prasugrel also suppressed donor GFP function upon mixing, suggesting the transfer of ticagrelor from patient platelets to donor platelets. This transfer did not lead to recovery of ADP responsiveness of patient's platelets. Conclusion Collectively, these observations support the concept that ticagrelor and/or its active metabolite in plasma or bound to platelets can inhibit donor platelets, which might compromise the effectiveness of platelet transfusion therapy. PMID- 29582545 TI - Viscoelastic properties of the posterior eye of normal subjects, patients with age-related macular degeneration, and pigs. AB - The purpose of this study is to measure, characterize, and compare the viscoelastic properties of the posterior eye of advanced dry age-related macular degeneration (AMD) patients, age-matched normal subjects, and pigs (3 groups). Ten horizontal and ten vertical strips of the macula retina and the underneath choroid and sclera were obtained for each group, respectively. They were examined by incremental stress-relaxation cycles in body-temperature saline. Mechanical response was characterized by the quasi-linear viscoelastic model. All the tissues were shown to be nonlinear viscoelastic. Stiffening and isotropization, increased relaxation, and softening and isotropization were found in AMD retina, choroid, and sclera, respectively, which are the mechanical features of the atherosclerotic process. The patients' medical records were in accordance with epidemiological studies indicating a relationship between the advanced AMD and atherosclerotic vascular disease (ASVD). Moreover, many differences were found between the viscoelastic properties of porcine and normal human retina, choroid, and sclera. The results suggest that AMD is associated with ASVD through a mechanism involving abnormal retinal, choroidal, and scleral mechanics similar to those seen in the atherosclerotic process. Moreover, researchers should be aware of mechanical differences when using porcine posterior eyes as a substitute for human posterior eyes. (c) 2018 Wiley Periodicals, Inc.

AB - The inner membrane complex and the apical secretory organelles are defining features of apicomplexan parasites. Despite their critical roles, the mechanisms behind the biogenesis of these structures in the malaria parasite Plasmodium falciparum are still poorly defined. We here show that decreasing expression of the P. falciparum homologue of the conserved endolysomal escorter Sortilin-VPS10 prevents the formation of the inner membrane complex and abrogates the generation of new merozoites. Moreover, protein trafficking to the rhoptries, the micronemes, and the dense granules is disrupted, which leads to the accumulation of apical complex proteins in the endoplasmic reticulum and the parasitophorous vacuole. We further show that protein export to the erythrocyte and transport through the constitutive secretory pathway are functional. Taken together, our results suggest that the malaria parasite P. falciparum Sortilin has potentially broader functions than most of its other eukaryotic counterparts.

AB - This is the third part of a three-part series of papers. In Part I, we presented a method for determining the actual effective geometry of a reference column as well as the thermodynamic-based parameters of a set of probe compounds in an in house mixture. Part II introduced an approach for estimating the actual effective geometry of a target column by collecting retention data of the same mixture of probe compounds on the target column and using their thermodynamic parameters, acquired on the reference column, as a bridge between both systems. Part III, presented here, demonstrates the retention time transfer and prediction from the reference column to the target column using experimental data for a separate mixture of compounds. To predict the retention time of a new compound, we first estimate its thermodynamic-based parameters on the reference column (using geometric parameters determined previously). The compound's retention time on a second column (of previously determined geometry) is then predicted. The models and the associated optimization algorithms were tested using simulated and experimental data. The accuracy of predicted retention times shows that the proposed approach is simple, fast, and accurate for retention time transfer and prediction between gas chromatography columns.

AB - AIMS: To evaluate various measures of haemoglobin (Hb) A1c variability, compared with average HbA1c, as independent predictors of mortality. MATERIALS AND METHODS: The Renal Insufficiency And Cardiovascular Events Italian multicentre study enroled 15 733 patients with type 2 diabetes from 19 diabetes clinics during 2006-2008. A total of 3 to 5 HbA1c measures, obtained during the 2-year period before enrolment, were available from 9 centres (8290 patients) and were used to calculate average HbA1c (HbA1c -MEAN) and HbA1c variability, measured as intra-individual standard deviation (HbA1c-SD), SD adjusted for the number of HbA1c assessments (HbA1c-AdjSD) and coefficient of variation (HbA1c-CV), that is, the HbA1c-SD to HbA1c-MEAN ratio. Vital status on October 31, 2015 was retrieved for 8252 patients (99.5%). RESULTS: The measures of HbA1c variability increased according to quartiles of HbA1c-MEAN and vice versa. HbA1c-MEAN and measures of HbA1c variability were associated with all-cause mortality; however, the strength of association of HbA1c-MEAN was lower than that of HbA1c -SD, HbA1c-CV or HbA1c AdjSD, and disappeared after adjusting for confounders and any of the measures of HbA1c variability. Mortality increased with quartiles of HbA1c-MEAN, HbA1c -SD, HbA1c-CV and HbA1c-AdjSD, but only the association with HbA1c variability measures remained after adjustment for confounders and/or each other measure. In the fully adjusted model, mortality risk was lower for HbA1c-SD below the median and higher for HbA1c-SD above the median, regardless of whether HbA1c-MEAN was below or above the median. Conclusions HbA1c variability is a strong, independent predictor of all-cause mortality in type 2 diabetes and appears to be even more powerful than average HbA1c in predicting mortality. PMID- 29582549 TI - Microglial immune response is impaired against the neurotropic fungus Lomentospora prolificans. AB - Lomentospora (Scedosporium) prolificans is an opportunistic pathogen capable of causing invasive infections in immunocompromised patients. The fungus is able to disseminate via the bloodstream finally arriving at the central nervous system producing neurological symptoms and, in many cases, patient death. In this context, microglial cells, which are the resident immune cells in the central nervous system, may play an important role in these infections. However, this aspect of anti-L. prolificans immunity has been poorly researched to date. Thus, the interactions and activity of microglial cells against L. prolificans were analysed, and the results show that there was a remarkable impairment in their performance regarding phagocytosis, the development of oxidative burst, and in the production of pro-inflammatory cytokines, compared with macrophages. Interestingly, L. prolificans displays great growth also when challenged with immune cells, even when inside them. We also proved that microglial phagocytosis of the fungus is highly dependent on mannose receptor and especially on dectin-1. Taken together, these data provide evidence for an impaired microglial response against L. prolificans and contribute to understanding the pathobiology of its neurotropism.

PMID- 29582550 TI - Consensus opinion on diagnosis and management of thrombotic microangiopathy in Australia and New Zealand. AB - Thrombotic microangiopathy (TMA) arises in a variety of clinical circumstances with the potential to cause significant dysfunction of the kidneys, brain, gastrointestinal tract and heart. TMA should be considered in all patients with thrombocytopenia and anaemia, with an immediate request to the haematology laboratory to look for red cell fragments on a blood film. Although TMA of any aetiology generally demands prompt treatment, this is especially so in thrombotic thrombocytopenic purpura (TTP) and atypical haemolytic uraemic syndrome (aHUS), where organ failure may be precipitous, irreversible and fatal. In all adults, urgent, empirical plasma exchange (PE) should be started within 4-8 h of presentation for a possible diagnosis of TTP, pending a result for ADAMTS13 (a disintegrin and metalloprotease thrombospondin, number 13) activity. A sodium citrate plasma sample should be collected for ADAMTS13 testing prior to any plasma therapy. In children, Shiga toxin-associated haemolytic uraemic syndrome due to infection with Escherichia coli (STEC-HUS) is the commonest cause of TMA, and is managed supportively. If TTP and STEC-HUS have been excluded, a diagnosis of aHUS should be considered, for which treatment is with the monoclonal complement C5 inhibitor, eculizumab. Although early confirmation of aHUS is often not possible, except in the minority of patients in whom auto-antibodies against factor H are identified, genetic testing ultimately reveals a complement-related mutation in a significant proportion of aHUS cases. The presence of other TMA associated conditions (e.g. infection, pregnancy/postpartum and malignant hypertension) does not exclude TTP or aHUS as the underlying cause of TMA.

AB - We sought to investigate whether magnesium oxide bound to soy protein (MGP) increases serum magnesium concentrations with less diarrhea compared to commonly prescribed magnesium salts. Subjects were switched to MGP at a near-equivalent daily elemental magnesium dose. Mean serum magnesium levels were compared. If magnesium levels remained <1.7 mg/dL after switching to MGP, subjects were enrolled into Part 2 and received a one-time MGP dose adjustment. The MGP daily dose was increased by 266 mg. For both parts 1 and 2, subjects recorded the number and quality of their stools to assess gastrointestinal (GI) tolerability of MGP. Twelve pediatric kidney transplant recipients completed Part 1. Mean serum magnesium levels increased from 1.61 (SD 0.1) on standard MG to 1.69 (SD 0.1); t(11) = 2.6, P = .02 on MGP. Five subjects completed Part 2, and all achieved serum magnesium >=1.7 mg/dL (mean 1.75 mg/dL, SD 0.06; t(4) = 2.7, P = .06). Subjects reported the same number of, but looser bowel movements with MGP; however, individuals did not perceive intolerable GI symptoms with MGP therapy and all chose to remain on MGP at the end of the study. At an equivalent mg/kg/d dose of elemental magnesium, serum magnesium levels on MGP were significantly higher. PMID- 29582553 TI - Farming system and wheat cultivar affect infestation of, and parasitism on, Cephus cinctus in the Northern Great Plains. AB - BACKGROUND: Cephus cinctus infestation causes $350 million in annual losses in the Northern Great Plains. We compared infestation and parasitism of C. cinctus in spring (including Kamut; Triticum turgidum ssp. turanicum) and winter wheat cultivars grown in organic and conventional fields in Montana, USA. In the greenhouse, we compared C. cinctus preference and survival in Kamut, Gunnison, and Reeder spring wheat cultivars. RESULTS: Stems cut by C. cinctus varied by farming system and the seasonality of the wheat crop. No stems of Kamut in organic fields were cut by C. cinctus, but 1.5% [+/-0.35% standard error (SE)] of stems in conventional spring wheat, 5% (+/-0.70% SE) of stems in organic winter wheat, and 20% (+/-0.93% SE) of stems in conventional winter wheat fields were cut by C. cinctus. More larvae of C. cinctus were parasitized in organic (27 +/- 0.03% SE) compared with conventional (5 +/- 0.01% SE) winter wheat fields. Cephus cinctus oviposition, survival, and the number of stems cut were lowest in Kamut compared with Gunnison and Reeder. CONCLUSION: Cephus cinctus infestation was more common in winter wheat than in spring wheat. Organic fields with fewer cut stems also supported more parasitoids. Kamut is a genetic resource for developing C. cinctus-resistant cultivars. (c) 2018 Society of Chemical Industry. PMID- 29582554 TI - Genetic counselors on the frontline of precision health. AB - By enabling precise genetic diagnosis and treatment there is great potential for inexpensive, accurate, and widely accessible genomic information to transform health care and improve the general well-being of virtually every person. To maximize this potential, approaches to genetic counseling and the role of genetic counselors will need to adapt to fit changing clinical and commercial needs worldwide. This will require overcoming multiple challenges including an inadequate workforce; development and implementation of alternate models of service delivery; integration of new technologies to improve, extend, and expand services; and support for equitable education and counseling among all populations. Genetic counselors are aptly poised to take on these challenges. The result will be better informed patients and families more capable of utilizing genetic information appropriately, making autonomous decisions about their care, and modifying their approach to disease risk to actively contribute to their health. The contributors to this issue of Seminars discuss how key areas of genetic counseling need to evolve and how genetic counselors can play a role in shaping the future of precision health.

In our continuous efforts to develop more potent PfDHODH inhibitors, a unique library of active ingredients from traditional Chinese medicine (TCM) has been collected and was screened in this study. Through the initial screening, we found that coptisine, a natural alkaloid from TCM Coptidis Rhizoma, was a novel and potent inhibitor of PfDHODH with an IC50 value of 1.83 +/- 0.08 MUm. At the same time, enzyme kinetic analysis using Lineweaver-Burk plot indicated that coptisine is an uncompetitive inhibitor for PfDHODH. Thermal shift assay and molecular docking simulation research reveal that coptisine is capable of binding with PfDHODH. Moreover, coptisine exhibits weak inhibition activity against human DHODH, indicating that coptisine is a selective inhibitor of PfDHODH. Taken together, our study highlights the potential of active ingredients in TCM as valuable resource for discovering novel chemical scaffolds for PfDHODH.

AB - AIM: Improving timely access to evidence-based treatment for people aged 14-65 years experiencing a first episode psychosis (FEP) or an at-risk mental state (ARMS) for psychosis is a national priority within the United Kingdom. An early intervention in psychosis (EIP) access and waiting time standard has been set which has extended the age range and acceptance criteria for services. METHODS: This descriptive evaluation reports upon the referrals and access to treatment times within an EIP service over the first year of operating in line with the access and waiting time standard. Patient pathways and post-assessment status are also described. RESULTS: The service received 406 referrals, of which 88% (n = 357) were assessed. The mean length of time to treatment was 1.5 weeks, with 88% being seen within 2 weeks. Of those who engaged in an assessment, 34% (n = 138) were identified as ARMS cases and 30% (n = 123) were identified as FEP. Over 35 year olds accounted for 22% (n = 80) of the total accepted cases. CONCLUSIONS: The findings indicate clinical and operational issues, which will need careful consideration in the future planning of services. The high number of ARMS cases highlights the importance of clear treatment pathways and targeted interventions and may suggest a need to commission distinct ARMS services. The number of people who met the extended age and service acceptance criteria may suggest a need to adapt or redesign clinical services to meet the age-specific needs of over 35 year olds and those with an ARMS. It is unclear how changes to the remit of EIP services will impact upon future clinical outcomes.

AB - AIM: The aim of this study was to examine stakeholders' views of how the establishment of the South West Radiation Oncology Service in Bunbury, Western Australia, has affected treatment decision-making, and the extent to which patients are involved in the decision-making process. METHODS: Semi-structured in depth interviews were undertaken with 21 service providers involved in the treatment and care of people with cancer, and 17 adults diagnosed with cancer who opted to undergo radiotherapy (RT) treatment at the Service. Data were subject to thematic analysis using the qualitative data analysis software NVivo 10. RESULTS: Patients were overwhelmingly positive about their experiences at the Service, praising the quality of the care provided and noting the convenience associated with receiving treatment locally. Most patients reported feeling involved in decision-making, but tended to rely on and generally adopt advice from medical professionals regarding type and location of treatment. Although service providers in the region had become more aware of the regional RT service and referrals had increased, some patients continued to travel to the metropolitan area for treatment. Reasons identified for this included the need for more specialized RT treatment and the more extensive range of allied health services offered. CONCLUSION: Increased convenience and a lower financial burden are key reasons why rural cancer patients prefer treatment at a regional RT service rather than travelling to metropolitan centers. These factors highlight the need for ongoing improvement in access to local RT services so that disparities in cancer outcomes between rural and metropolitan patients are reduced.

AB - We aimed to increase pathologic complete response (pCR) in patients with invasive breast cancer by adding preoperative capecitabine to docetaxel following 5 fluorouracil, epirubicin, cyclophosphamide (FEC) (with trastuzumab for patients with HER2-positive disease) and to evaluate 5-year disease-free survival (DFS) associated with this preoperative regimen. Chemotherapy included four cycles of FEC100 (5-fluorouracil 500 mg/m2 , epirubicin 100 mg/m2 , cyclophosphamide 500 mg/m2 IV on Day 1 every 21 days) followed by 4 21-day cycles of docetaxel (35 mg/m2 days 1 and 8) concurrently with capecitabine (825 mg/m2 orally twice daily for 14 days followed by 7 days off) (wTX). For HER2-positive patients, treatment was modified by decreasing epirubicin to 75 mg/m2 and adding trastuzumab (H) in standard doses (FEC75-H ->wTX-H). The study objective was to achieve a pCR rate in the breast and axillary lymph nodes of 37% in patients with HER2-negative breast cancer and of 67% in patients with HER2-positive breast cancer treated with preoperative trastuzumab. A total of 186 patients were enrolled on study. In an intent-to-treat analysis, the pCR rate was 31% (37/118, 95% CI: 24-40%) in the HER2-negative patients, 24% (15/62, 95% CI: 14-37%) in ER-positive/HER2-negative patients, 39% (22/56, 95% CI: 27-53%) in the ER-negative/HER2-negative patients, and 46% (29/63, 95% CI: 34-48%) in the HER2-positive patients. The pCR rate in the 40 trastuzumab-treated patients was 53% (21/40, 95% CI: 38-67%). Grade 3 and 4 adverse events included neutropenia, leukopenia, diarrhea, and hand-foot skin reactions. One trastuzumab-treated patient developed grade 3 cardiotoxicity, and 4 others experienced grade 1-2 decrements in left ventricular function; all five patients' cardiac function returned to their baseline upon completion of trastuzumab. At 5 years, disease-free survival was 70% in the HER2-negative population (78% in ER-positive/HER2-negative and 62% in the ER-negative/HER2 negative patients) and 80% in the HER2-positive patients (87% in the trastuzumab treated HER2-positive patients). At 5 years, overall survival was 80% in the HER2 negative population (88% in ER-positive/HER2-negative and 71% in the ER negative/HER2-negative patients) and 86% in the HER2-positive patients (94.5% in the trastuzumab-treated HER2-positive patients). FEC100 (FEC75 with trastuzumab) followed by weekly docetaxel plus capecitabine, with or without trastuzumab is a safe, effective preoperative cytotoxic regimen. However, the addition of capecitabine to docetaxel following FEC, with or without trastuzumab, did not increase pCR rates nor 5-year DFS over the rates that have been reported with standard preoperative doxorubicin/cyclophosphamide (AC) followed by paclitaxel, with or without trastuzumab. Therefore, the use of capecitabine as part of preoperative chemotherapy is not recommended. PMID- 29582559 TI - Preclinical pharmacokinetics and biodistribution of subcutaneously administered glycoPEGylated recombinant factor VIII (N8-GP) and development of a human pharmacokinetic prediction model. AB - : Essentials N8-GP is an extended half-life recombinant factor VIII (FVIII) for the treatment of hemophilia A. Subcutaneous (SC) FVIII dosing might reduce the treatment burden of prophylaxis. SC N8-GP has a favorable PK profile in animal models and disappears from skin injection sites. Combined animal (SC) and clinical (IV) data suggest that daily SC dosing may provide prophylaxis. SUMMARY: Background N8-GP is an extended half-life recombinant factor VIII (FVIII) for the treatment of hemophilia A. Subcutaneous administration of FVIII may reduce the treatment burden of prophylaxis; however, standard FVIII products have low bioavailability after subcutaneous dosing in animals. Objective To evaluate the pharmacokinetics, effectiveness and local distribution of subcutaneously administered N8-GP in preclinical models and predict the human pharmacokinetic (PK) profile. Methods The pharmacokinetics of subcutaneously administered N8-GP were evaluated in FVIII knockout (F8-KO) mice and cynomolgus monkeys; a human PK prediction model in hemophilia A patients was developed. The hemostatic effect was evaluated in a tail vein bleeding model in F8-KO mice. The injection-site distribution and absorption of subcutaneously administered N8-GP were assessed in F8-KO mice by the use of temporal fluorescence imaging and immunohistochemistry. Results Subcutaneously administered N8-GP had a bioavailability, a first-order absorption rate and a half-life, respectively, of 24%, 0.094 h-1 and 14 h in F8 KO mice, and 26%, 0.33 h-1 and 15 h in cynomolgus monkeys. A dose-dependent effect of subcutaneously administered N8-GP on blood loss was observed in mice. A minimal amount of N8-GP was detected at the injection site 48-72 h after single or multiple dose(s) in F8-KO mice. Subcutaneously administered N8-GP was localized to the skin around the injection site, with time-dependent disappearance from the depot. PK modeling predicted that subcutaneously administered N8-GP at a daily dose of 12.5 IU kg-1 will provide FVIII trough levels of 2.5-10% in 95% of patients with severe hemophilia A. Conclusions Subcutaneously administered N8-GP may provide effective hemophilia A prophylaxis. A phase I clinical trial is underway to investigate this possibility.

PMID- 29582561 TI - Effects of locally administered rhBMP-2 and bisphosphonate on bone regeneration in the rat fibula. AB - OBJECTIVE: To evaluate the ability of xenogenic bone and absorbable collagen sponge to function as an rhBMP-2 carrier and the osteoinductivity of bisphosphonate by comparison with recombinant human bone morphogenetic protein-2 (rhBMP-2). MATERIALS AND METHODS: Thirty-two Sprague-Dawley male rats were divided into four groups. Segmental ostectomy of both fibulae was performed, and the defect area was then treated with Rapiderm Pad (absorbable collagen sponge; COL_BMP) or CollaOss (xenogenic bone; XENO_BMP) with application of rhBMP-2. Alternatively, both fibulae were grafted with xenogenic bone with different bisphosphonate concentrations (XENO_Low BP, XENO_High BP). After 4 or 8 weeks, animals were sacrificed, and radiographic, histological, histomorphometric, and immunohistochemical analyses were performed. RESULTS: Recombinant human bone morphogenetic protein-2 promoted bone formation, regardless of the carrier, and exhibited continuity between the graft material and defect area. Moreover, the results showed that higher concentrations of bisphosphonate were associated with greater bone formation than lower concentrations of bisphosphonate. CONCLUSION: Absorbable collagen sponges with rhBMP-2 were advantageous in that there was no remaining graft material and that the bone was remodeled to resemble the existing fibula. The local application of bisphosphonate promoted new bone formation, particularly when used at high concentrations. High-concentration bisphosphonate induced new bone formation comparable to rhBMP-2 with lesser remaining bone material. PMID- 29582562 TI - Description, evaluation and scale-up potential of a model for rapid access to early intervention for psychosis. AB - AIM: This paper aims to describe the entry protocol of the Prevention and Early Intervention for Psychosis Program (PEPP)-Montreal, an early intervention program for psychosis. The protocol is designed to fulfil a key objective of the early intervention movement-reducing delays to accessing high-quality care. The paper also aims to describe how this rapid entry protocol can be deployed in other services interested in reducing delays in initiating treatment. METHODS: PEPP provides rapid, easy access to quality care by placing a single, well-trained professional, the intake clinician, at the point of entry. Anyone can refer a youth directly and without formalities to the intake clinician who responds promptly and sensitively to all help-seeking, whether by a youth, a family member, a school counsellor or anyone acting on behalf of a youth in need. To promote accessibility, PEPP guarantees an initial assessment within 72 hours; maintains relationships with referral sources; and conducts awareness-enhancing outreach activities. RESULTS: Since 2003, PEPP has received 1750 referrals, which have all been responded to within 72 hours. Families have been involved in the intake process in 60% of the cases and hospitalization may have been averted in over half of the referrals originating from emergency-room services. Another indicator of success is the very low turnover in the intake clinician's position. Overall, the PEPP model has succeeded in providing rapid, engaging, easy and youth-friendly access to high-quality care. CONCLUSION: The success of this protocol at PEPP has inspired the entry protocols at other first-episode psychosis services. Its ability to provide rapid, engaging access to high-quality services may allow this protocol to become a model for other early intervention services for psychosis and other mental illnesses. PMID- 29582563 TI - Prognostic role of circulating tumor cells in patients with EGFR-mutated or ALK rearranged non-small cell lung cancer. AB - BACKGROUND: Circulating tumor cell (CTC) counts at baseline and follow-up are an independent prognostic factor in patients receiving standard chemotherapy for non small cell lung cancer (NSCLC). This study further explored the role of CTCs in EGFR-mutated and ALK-rearranged NSCLC patients administered targeted therapies as first-line treatment. METHODS: CTCs were enumerated with a novel high-efficiency detection method from the blood of 43 patients with EGFR-mutated or ALK rearranged NSCLC at baseline and at disease-progression. Patients were stratified into favorable and unfavorable groups with baseline CTC counts of < 8 or >= 8 CTCs/3.2 mL, respectively. RESULTS: A total of 76.7% of the patients were positive for >= 2 CTCs /3.2 ml blood at baseline. The median progression-free survival (PFS) and overall survival (OS) rates of the favorable compared to the unfavorable group were longer (11.6 vs. 8.5 months, P = 0.004 for PFS; 21.00 vs. 17.7 months, P = 0.013 for OS). Multivariate analysis demonstrated that baseline CTC count was a strong predictor of PFS (hazard ratio 2.835; 95% confidence interval 1.240-6.483; P = 0.014) and OS (hazard ratio 3.317; 95% confidence interval 1.360-8.092; P = 0.008). CONCLUSION: Baseline CTC count could be a predictive biomarker for EGFR-mutated and ALK-rearranged NSCLCs, which allows for better guidance and monitoring of patients over the course of molecular targeted therapies. PMID- 29582565 TI - IKKs and tumor cell plasticity. AB - Nuclear factor kappaB (NF-kappaB) transcription factors are the central hubs of signaling pathways connecting proinflammatory signals to cell survival, proliferation and cytokine production. In cancers, NF-kappaB signaling influences many aspects of tumor development, from initiation to metastasis. These functions are mediated by tumor-induced plasticity that allows tumor cells to adapt and survive in changing conditions within the tumor microenvironment. Tumor cell plasticity is shaped by the inflammatory microenvironment in tumors. This review focuses on inhibitor of NF-kappaB kinases, the direct upstream elements of NF kappaB regulation, specifically on their conventional and non-conventional functions in animal models of tumorigenesis from the recent literature. PMID- 29582566 TI - Quantitative time domain analysis of lifetime-based Forster resonant energy transfer measurements with fluorescent proteins: Static random isotropic fluorophore orientation distributions. AB - Forster resonant energy transfer (FRET) measurements are widely used to obtain information about molecular interactions and conformations through the dependence of FRET efficiency on the proximity of donor and acceptor fluorophores. Fluorescence lifetime measurements can provide quantitative analysis of FRET efficiency and interacting population fraction. Many FRET experiments exploit the highly specific labelling of genetically expressed fluorescent proteins, applicable in live cells and organisms. Unfortunately, the typical assumption of fast randomization of fluorophore orientations in the analysis of fluorescence lifetime-based FRET readouts is not valid for fluorescent proteins due to their slow rotational mobility compared to their upper state lifetime. Here, previous analysis of effectively static isotropic distributions of fluorophore dipoles on FRET measurements is incorporated into new software for fitting donor emission decay profiles. Calculated FRET parameters, including molar population fractions, are compared for the analysis of simulated and experimental FRET data under the assumption of static and dynamic fluorophores and the intermediate regimes between fully dynamic and static fluorophores, and mixtures within FRET pairs, is explored. Finally, a method to correct the artefact resulting from fitting the emission from static FRET pairs with isotropic angular distributions to the (incorrect) typically assumed dynamic FRET decay model is presented. PMID- 29582564 TI - Genetic variants in mRNA untranslated regions. AB - Genome Wide Association Studies (GWAS) have mapped thousands of genetic variants associated with complex disease risk and regulating quantitative traits, thus exploiting an unprecedented high-resolution genetic characterization of the human genome. A small fraction (3.7%) of the identified associations is located in untranslated regions (UTRs), and the molecular mechanism has been elucidated for few of them. Genetic variations at UTRs may modify regulatory elements affecting the interaction of the UTRs with proteins and microRNAs. The overall functional consequences include modulation of messenger RNA (mRNA) transcription, secondary structure, stability, localization, translation, and access to regulators like microRNAs (miRNAs) and RNA-binding proteins (RBPs). Alterations of these regulatory mechanisms are known to modify molecular pathways and cellular processes, potentially leading to disease processes. Here, we analyze some examples of genetic risk variants mapping in the UTR regulatory elements. We describe a recently identified genetic variant localized in the 3'UTR of the TNFSF13B gene, associated with autoimmunity risk and responsible of an increased stability and translation of TNFSF13B mRNA. We discuss how the correct use and interpretation of public GWAS repositories could lead to a better understanding of etiopathogenetic mechanisms and the generation of robust biological hypothesis as starting point for further functional studies.

PMID- 29582567 TI - Association of family history and survival in patients with colorectal cancer: a pooled analysis of eight epidemiologic studies. AB - A family history of colorectal cancer (CRC) in first-degree relatives (FDRs) increases the risk of CRC. However, the influence of family history on survival among CRC patients remains unclear. We conducted a pooled analysis of survival in 5010 incident CRC cases. Cox proportional hazards models were used to estimate the association of family history with overall survival (OS) and CRC-specific survival (CSS). We also assessed the impact of the number of affected FDRs and age at CRC diagnosis in the affected FDRs on survival. Among CRC cases, 819 (16%) patients reported a family history of CRC. There were 1580 total deaths over a median follow-up of 4.6 years, of which 1046 (66%) deaths were due to CRC. Having a family history of CRC was not associated with OS [hazard ratio (HR), 1.03; 95% confidence interval (CI), 0.89-1.19] or CSS (HR, 1.13; 95% CI, 0.95-1.36)]. There were no associations between the number of affected relatives or age at CRC diagnosis of the affected relative with survival (all Ptrend > 0.05). However, a family history of CRC did confer worse CSS in patients diagnosed with distal colon cancer (HR, 1.45, 95% CI, 1.03-2.04). A family history of CRC was generally not associated with survival after CRC diagnosis. However, having a family history of CRC was associated with worse CRC prognosis in individuals with distal colon cancer, suggesting a possible genetic predisposition with distinct pathogenic mechanism that may lead to worse survival in this group.

PMID- 29582569 TI - The potential of plant microbiota in reducing postharvest food loss. AB - The role of the plant microbiota in plant establishment, growth and health is well studied, but the dynamics of postharvest crop microbiota and its role in postharvest crop quality are largely unexplored, although food loss is an enormous issue worldwide. The microbiota might be especially important during crop storage by either preventing or favouring rots, or quality loss due to, for example, sprouting, saccharification, water loss or spoilage. We need more research on plant-microbe interactions in postharvest crops to be in future able to provide microbial solutions for plant production along the whole food chain from field to fork. PMID- 29582571 TI - Comprehensive assessment of insulin resistance in non-obese Asian Indian and Chinese men. AB - AIMS/INTRODUCTION: Indian individuals are more insulin resistant (IR) than Chinese individuals, even among those with a non-obese body mass index (BMI). However, BMI often underestimates body fat in Indian individuals, and it remains unclear whether Indians would remain more IR than Chinese individuals when both BMI and body fat are equally matched. MATERIALS AND METHODS: Using the hyperinsulinemic-euglycemic clamp with stable-isotope infusion, we comprehensively assessed IR between 13 non-obese Indian men with 13 Chinese men matched for age, BMI and body fat. We further compared the differences in insulin metabolic clearance rate (MCR) between the two groups and its relationship with various metabolic parameters. The response of lipid and amino acid metabolism to insulin stimulation was also evaluated using metabolomic profiling. RESULTS: The rates of endogenous glucose production during fasting were similar, and endogenous glucose production was completely suppressed during insulin clamp for both ethnic groups. Glucose disappearance during insulin clamp was also similar between the two groups, even after accounting for differences in insulin concentration. Metabolomic profiles of amino acids and various acylcarnitines were similar during both fasting and insulin clamp. However, plasma insulin during clamp was significantly higher in Indian men, indicating that insulin MCR was lower. Insulin MCR correlated significantly with total adiposity and skeletal muscle insulin sensitivity. CONCLUSION: When equally matched for body fat, non obese Indian men had similar skeletal muscle insulin sensitivity and endogenous glucose production to Chinese men. The effects of insulin on lipid and amino acid metabolism were also similar. Low insulin MCR is associated with greater adiposity and lower skeletal muscle insulin sensitivity. PMID- 29582572 TI - Linking Cognitive and Social Aspects of Sound Change Using Agent-Based Modeling. AB - The paper defines the core components of an interactive-phonetic (IP) sound change model. The starting point for the IP-model is that a phonological category is often skewed phonetically in a certain direction by the production and perception of speech. A prediction of the model is that sound change is likely to come about as a result of perceiving phonetic variants in the direction of the skew and at the probabilistic edge of the listener's phonological category. The results of agent-based computational simulations applied to the sound change in progress, /u/-fronting in Standard Southern British, were consistent with this hypothesis. The model was extended to sound changes involving splits and mergers by using the interaction between the agents to drive the phonological reclassification of perceived speech signals. The simulations showed no evidence of any acoustic change when this extended model was applied to Australian English data in which /s/ has been shown to retract due to coarticulation in /str/ clusters. Some agents nevertheless varied in their phonological categorizations during interaction between /str/ and /?tr/: This vacillation may represent the potential for sound change to occur. The general conclusion is that many types of sound change are the outcome of how phonetic distributions are oriented with respect to each other, their association to phonological classes, and how these types of information vary between speakers that happen to interact with each other. PMID- 29582573 TI - Regulation of melanocyte stem cell behavior by the niche microenvironment. AB - Somatic stem cells are regulated by their niches to maintain tissue homeostasis and repair throughout the lifetime of an organism. An excellent example to study stem cell/niche interactions is provided by the regeneration of melanocytes during the hair cycle and in response to various types of injury. These processes are regulated by neighboring stem cells and multiple signaling pathways, including WNT/beta-catenin, KITL/KIT, EDNs/EDNRB, TGF-beta/TGF-betaR, alpha MSH/MC1R, and Notch signaling. In this review, we highlight recent studies that have advanced our understanding of the molecular crosstalk between melanocyte stem cells and their neighboring cells, which collectively form the niche microenvironment, and we focus on the question of how McSCs/niche interactions shape the responses to genotoxic damages and mechanical injury. PMID- 29582575 TI - Rheoreversible Metallogels Derived from Coordination Polymers. AB - A series of mixed-ligand-based CdII /CoII coordination polymers (CPs) that were derived from two bis(pyridyl)-bis(amide) ligands, 4,4'-oxybis(N-(pyridin-3 yl)benzamide) (LP) and 4,4'-oxybis(N-(pyridin-4-yl)benzamide) (LP1), and a variety of dicarboxylates isophthalates, terephthalates, 1,2 carboxytranscinamates, and 1,3- and 1,4-phenylene dicarboxylates were synthesized based on a rationale that they would occlude solvate guests inside their crystal lattice, thereby rendering these CPs suitable as metallogelators. The CPs were characterized by using single-crystal X-ray diffraction, elemental analysis, powder X-ray diffraction (PXRD), FTIR spectroscopy, and thermogravimetric analysis (TGA). Structural analyses revealed that the majority of the CPs were lattice-occluded molecular solids, which provided us with an opportunity to study their gelation behavior. We observed that, out of eight CPs that were tested, seven were able to produce metallogels. A thorough study of the rheological behavior of the metallogels was performed and CPG1, CPG2, CPG4, and CPG5 were found to exhibit rheoreversible behavior, which was further confirmed by rheological experiments. Interestingly, ligand LP was found to form an aqueous gel, which was exploited to produce silver nanoparticles. PMID- 29582576 TI - Experimental versus theoretical log D7.4 , pKa and plasma protein binding values for benzodiazepines appearing as new psychoactive substances. AB - The misuse of benzodiazepines as new psychoactive substances is an increasing problem around the world. Basic physicochemical and pharmacokinetic data is required on these substances to interpret and predict their effects upon humans. Experimental log D7.4 , pKa and plasma protein binding values were determined for 11 benzodiazepines that have recently appeared as new psychoactive substances (3 hydroxyphenazepam, 4'-chlorodiazepam, desalkylflurazepam, deschloroetizolam, diclazepam, etizolam, flubromazepam, flubromazolam, meclonazepam, phenazepam, and pyrazolam) and compared with values generated by various software packages (ACD/I lab, MarvinSketch, ADMET Predictor and PreADMET). ACD/I-LAB returned the most accurate values for log D7.4 and plasma protein binding while ADMET Predictor returned the most accurate values for pKa . Large variations in predictive errors were observed between compounds. Experimental values are currently preferable and desirable as they may aid with the future 'training' of predictive models for these new psychoactive substances.

AB - Infectious diseases caused by pathogenic bacteria, especially multidrug-resistant bacteria, and their global spreading have become serious public health concerns. Early diagnosis and effective therapy can efficiently prevent deterioration and further spreading of the infections. There is an urgent need for sensitive, selective, and facile diagnosis as well as therapeutically potent treatment. The emergence of nanotechnology has provided more options for diagnosis and treatments of bacterial infections. Metal nanoparticles and metal oxide nanoparticles have drawn intense attention owing to their unique optical, magnetic, and electrical properties. These versatile metal-based nanoparticles have great potential for selective detection of bacteria and/or therapy. This review gives an overview of recent efforts on developing various metal-based nanoparticles for bacterial detection and infection therapy. It begins with an introduction of fundamental concepts and mechanisms in designing diagnostic and therapeutic strategies. Representative achievements are selected to illustrate the proof-of-concept in vitro and in vivo applications. A brief discussion of challenges and perspective outlook in this field is provided at the end of this review. PMID- 29582579 TI - 3D Interconnected Mesoporous Alumina with Loaded Hemoglobin as a Highly Active Electrochemical Biosensor for H2 O2. AB - Alumina is one of the most common and stable metal oxides in nature, which has been developed as a novel adsorbent in enrichment of biomolecules due to its excellent affinity to phosphor or amino groups. In this study, ordered mesoporous alumina (OMA) with interconnected mesopores and surface acidic property is synthesized through a solvent evaporation induced co-assembly process using poly(ethylene oxide)-b-polystyrene (PEO-b-PS) diblock copolymer as a template and aluminium acetylacetonate (Al(acac)3 ) as the aluminium source. The pore size (12.1-19.7 nm), pore window size (3.5-9.0 nm) and surface acidity (0.092-0.165 mmol g-1 ) can be precisely adjusted. The highly porous structure endows the OMA materials with high hemoglobin (Hb) immobilization capacity (170 mg g-1 ). The obtained Hb@OMA composite is used as an electrocatalyst of biosensor for convienet and fast detection of hydrogen peroxide (H2 O2 ) with a low H2 O2 detection limit of 1.7 * 10-8 m and a wide linear range of 2.5 * 10-8 to 5.0 * 10 5 m. Moreover, the Hb@OMA sensors show a good performance in real time detection of H2 O2 released from Homo sapiens bone osteosarcoma, indicating their potential application in complex biological processes.

AB - Malignant glioma is one of the most challenging central nervous system diseases to treat and has high rates of recurrence and mortality. Current therapies often fail to control tumor progression or improve patient survival. Marinobufagenin (MBG) is an endogenous mammalian cardiotonic steroid involved in sodium pump inhibition. Currently, various studies have indicated the potential of MBG in cancer treatments; however, the precise mechanisms are poorly understood. The functions of MBG were examined using colony formation, migration, cell cycle, and apoptosis assays in glioma cells. A mitochondrial membrane potential assay was performed to determine the mitochondrial transmembrane potential change, and cytochrome c release from mitochondria was assayed by fluorescence microscopy. An immunofluorescence assay was performed, and the nuclear translocation of NF kappaB in glioma cells was confirmed by confocal microscopy. Western blotting and RT-qPCR were used to detect the protein and gene expression levels, respectively. In addition, transfection experiment of ATP1A1-siRNA was further carried out to confirm the role of sodium pump alpha1 subunit in the anticancer effect of MBG in human glioma. The apoptosis-promoting and anti-inflammatory effects of MBG were further investigated, and the sodium pump alpha1 subunit and the ERK signaling pathway were found to be involved in the anticancer effect of MBG. The in vivo anticancer efficacy of MBG was also tested in xenografts in nude mice. Thus, therapies targeting the ERK signaling-mediated mitochondrial apoptotic pathways regulated by MBG might represent potential treatments for human glioma, and this study could accelerate the finding of newer therapeutic approaches for malignant glioma treatment.

We investigated intracellular fates of S. pneumoniae and found that the pathogen is entrapped by selective autophagy in pneumolysin- and ubiquitin-p62 LC3 cargo-dependent manners. Importantly, following induction of autophagy, Rab41 was relocated from the Golgi apparatus to S. pneumoniae-containing autophagic vesicles (PcAV), which were only formed in the presence of Rab41-positive intact Golgi apparatuses. Moreover, subsequent localization and regulation of K48- and K63-linked polyubiquitin chains in and on PcAV were clearly distinguishable from each other. Finally, we found that E3 ligase Nedd4-1 was recruited to PcAV and played a pivotal role in K63-linked polyubiquitin chain (K63Ub) generation on PcAV, promotion of PcAV formation, and elimination of intracellular S. pneumoniae. These findings suggest that Nedd4-1-mediated K63Ub deposition on PcAV acts as a scaffold for PcAV biogenesis and efficient elimination of host cell invaded pneumococci.

AB - OBJECTIVES: Mentalization-based treatment (MBT), originally designed for patients with borderline personality disorder (BPD), may be particularly indicated for severe conditions. However, there is limited documentation of how increasing severity of personality disorder (PD) effect outcomes of highly specialized treatments. This study aimed to investigate associations between clinical severity and outcomes for patients in MBT as compared to a psychodynamic group based treatment programme (PDT). DESIGN: A naturalistic, longitudinal, comparison study. METHODS: The sample included 345 patients with BPD (PDTn = 281, MBTn = 64). The number of diagnosed PDs, PD criteria, and symptom disorders were chosen as baseline indicators of clinical severity. Clinical outcomes (global functioning, symptom distress, interpersonal problems) were repeatedly assessed over three years. Therapists' fidelity to MBT was satisfactory. Linear mixed models were the applied statistics. RESULTS: In PDT, greater clinical severity was associated with poorer improvement rates. Clinical severity was not associated with significant differences in outcomes for patients in MBT. Differences in outcomes for patients in MBT and PDT increased significantly with higher severity of disorder. CONCLUSIONS: Supporting previous research, this study indicates that clinical benefits associated with MBT also apply for BPD patients with severe conditions. The results also suggest that increasing severity was a challenge in PDT. PRACTITIONER POINTS: MBT may be particularly beneficial for severely disordered BPD patients Differences between MBT and PDT were less pronounced in moderately disordered BPD patients. PMID- 29582582 TI - miRNA-23a/27a attenuates muscle atrophy and renal fibrosis through muscle-kidney crosstalk. AB - BACKGROUND: The treatment of muscle wasting is accompanied by benefits in other organs, possibly resulting from muscle-organ crosstalk. However, how the muscle communicates with these organs is less understood. Two microRNAs (miRs), miR-23a and miR-27a, are located together in a gene cluster and regulate proteins that are involved in the atrophy process. MiR-23a/27a has been shown to reduce muscle wasting and act as an anti-fibrotic agent. We hypothesized that intramuscular injection of miR-23a/27a would counteract both muscle wasting and renal fibrosis lesions in a streptozotocin-induced diabetic model. METHODS: We generated an adeno-associated virus (AAV) that overexpresses the miR-23a~27a~24-2 precursor RNA and injected it into the tibialis anterior muscle of streptozotocin-induced diabetic mice. Muscle cross-section area (immunohistology plus software measurement) and muscle function (grip strength) were used to evaluate muscle atrophy. Fibrosis-related proteins were measured by western blot to monitor renal damage. In some cases, AAV-GFP was used to mimic the miR movement in vivo, allowing us to track organ redistribution by using the Xtreme Imaging System. RESULTS: The injection of AAV-miR-23a/27a increased the levels of miR-23a and miR 27a as well as increased phosphorylated Akt, attenuated the levels of FoxO1 and PTEN proteins, and reduced the abundance of TRIM63/MuRF1 and FBXO32/atrogin-1 in skeletal muscles. It also decreased myostatin mRNA and protein levels as well as the levels of phosphorylated pSMAD2/3. Provision of miR-23a/27a attenuates the diabetes-induced reduction of muscle cross-sectional area and muscle function. Curiously, the serum BUN of diabetic animals was reduced in mice undergoing the miR-23a/27a intervention. Renal fibrosis, evaluated by Masson trichromatic staining, was also decreased as were kidney levels of phosphorylated SMAD2/3, alpha smooth muscle actin, fibronectin, and collagen. In diabetic mice injected intramuscularly with AAV-GFP, GFP fluorescence levels in the kidneys showed linear correlation with the levels in injected muscle when examined by linear regression. Following intramuscular injection of AAV-miR-23a~27a~24-2, the levels of miR-23a and miR-27a in serum exosomes and kidney were significantly increased compared with samples from control virus-injected mice; however, no viral DNA was detected in the kidney. CONCLUSIONS: We conclude that overexpression of miR 23a/27a in muscle prevents diabetes-induced muscle cachexia and attenuates renal fibrosis lesions via muscle-kidney crosstalk. Further, this crosstalk involves movement of miR potentially through muscle originated exosomes and serum distribution without movement of AAV. These results could provide new approaches for developing therapeutic strategies for diabetic nephropathy with muscle wasting. PMID- 29582583 TI - A Cascade-Targeting Nanocapsule for Enhanced Photothermal Tumor Therapy with Aid of Autophagy Inhibition. AB - Autophagy is a homeostatic lysosome-dependent metabolic process to eliminate damaged or dysfunctional cellular organelles, which is closely associated with tumor progression. Indocyanine green (ICG) can convert NIR light energy to localized heat for cancer cell and tissue ablation. However, the effect of autophagy modulation on ICG-mediated photothermal therapy remains unknown. In this study, it is found that primaquine (PQ) suppresses autophagy flux at a late stage through the impeding fusion of the autophagosome with the lysosome to form an autophagolysosome, leading to cell apoptosis or necrosis. This autophagosome lysosome fusion inhibitory effect and the autophagosome accumulation are more evident in the photothermal therapy combined with autophagy inhibition. Motivated by this notable effect, a cascade-targeting nanocapsule (HCP) is constructed using an organic solvent-free strategy to coencapsulate PQ and ICG. By targeting the cluster designation 44 molecule and sequentially enhancing the cell penetrating peptide-mediated endocytosis, the codelivery of PQ/ICG by HCP achieves selective recognition and reinforces the internalization by MCF-7 cells to exert a synergistic therapeutic effect on MCF-7 cells both in vitro and in vivo. The HCP system for the photothermal and autophagy inhibition combination therapy represents a novel strategy for the treatment of breast cancer. PMID- 29582585 TI - Low-level laser therapy as an adjunct to connective tissue graft procedure in the treatment of gingival recession defects: A systematic review and meta-analysis. AB - OBJECTIVE: The aim of this study was to systematically evaluate the effectiveness of low level laser therapy (LLLT) as an adjunct to connective tissue graft (CTG) procedure for the treatment of gingival recession (GR). MATERIALS AND METHODS: The addressed PICO question was; "In patients with Miller Class I or II recession defects (Population), what is the effect of LLLT as adjunct to CTG (Intervention) in comparison to CTG alone (Comparison) on gingival recession depth (Outcome)" Electronic databases were searched up to December 2017. Primary outcomes included gingival recession depth (GRD), whereas secondary outcomes were width of keratinized tissue (WKT) and relative clinical attachment level gain (RCAL). The weighted mean differences (WMD) of outcomes and 95% confidence intervals (CI) for each variable were calculated using random effect model. RESULTS: Four randomized clinical studies were included. Two studies showed significantly greater improvements with LLLT whereas, 2 studies showed comparable outcomes between LLLT and CTG group. Considering the effects of adjunctive LLLT as compared to CTG, a high degree of heterogeneity for GRD (Q value = 9.40, P = .02, I2 =68.11%) and WKT ((Q value = 16.04, P = .001, I2 =81.31%) was noticed among both the groups. Meta-analysis showed a statistically significant GRD (WMD= -0.61, 95% CI= -1.23 to 0.004, P = .05) for LLLT + CTG treatment versus CTG alone only. CONCLUSIONS: LLLT improves clinical and patient-centered outcomes of CTG procedures for the treatment of GR remains debatable. However, due to the small number of included studies and high heterogeneity in the laser parameters, precautions must be exercised when interpreting the results of the present systematic review. CLINICAL SIGNIFICANCE: Gingival recessions in dentistry are of major esthetic concern. Minimal gingival recessions can be treated by flap operations, but the predictability and stability of the outcomes is debatable. In the present review, low level laser therapy (LLLT) adjunct to connective tissue graft (CTG) depicted a significant improvement in the predictability and stability of root coverage outcomes compared with CTG alone. PMID- 29582584 TI - Dysregulation of metabolic-associated pathways in muscle of breast cancer patients: preclinical evaluation of interleukin-15 targeting fatigue. AB - BACKGROUND: Breast cancer patients report a perception of increased muscle fatigue, which can persist following surgery and standardized therapies. In a clinical experiment, we tested the hypothesis that pathways regulating skeletal muscle fatigue are down-regulated in skeletal muscle of breast cancer patients and that different muscle gene expression patterns exist between breast tumour subtypes. In a preclinical study, we tested the hypothesis that mammary tumour growth in mice induces skeletal muscle fatigue and that overexpression of the cytokine interleukin-15 (IL-15) can attenuate mammary tumour-induced muscle fatigue. METHODS: Early stage non-metastatic female breast cancer patients (n = 14) and female non-cancer patients (n = 6) provided a muscle biopsy of the pectoralis major muscle during mastectomy, lumpectomy, or breast reconstruction surgeries. The breast cancer patients were diagnosed with either luminal (ER+ /PR+ , n = 6), triple positive (ER+ /PR+ /Her2/neu+ , n = 5), or triple negative (ER- /PR- /Her2/neu- , n = 3) breast tumours and were being treated with curative intent either with neoadjuvant chemotherapy followed by surgery or surgery followed by standard post-operative therapy. Biopsies were used for RNA sequencing to compare the skeletal muscle gene expression patterns between breast cancer patients and non-cancer patients. The C57BL/6 mouse syngeneic mammary tumour cell line, E0771, was used to induce mammary tumours in immunocompetent mice, and isometric muscle contractile properties and fatigue properties were analysed following 4 weeks of tumour growth. RESULTS: RNA-sequencing and subsequent bioinformatics analyses revealed a dysregulation of canonical pathways involved in oxidative phosphorylation, mitochondrial dysfunction, peroxisome proliferator-activated receptor signalling and activation, and IL-15 signalling and production. In a preclinical mouse model of breast cancer, the rate of muscle fatigue was greater in mice exposed to mammary tumour growth for 4 weeks, and this greater muscle fatigue was attenuated in transgenic mice that overexpressed the cytokine IL-15. CONCLUSIONS: Our data identify novel genes and pathways dysregulated in the muscles of breast cancer patients with early stage non metastatic disease, with particularly aberrant expression among genes that would predispose these patients to greater muscle fatigue. Furthermore, we demonstrate that IL-15 overexpression can attenuate muscle fatigue associated with mammary tumour growth in a preclinical mouse model of breast cancer. Therefore, we propose that skeletal muscle fatigue is an inherent consequence of breast tumour growth, and this greater fatigue can be targeted therapeutically. PMID- 29582586 TI - Huntington's disease: From basic science to therapeutics. PMID- 29582588 TI - Altered lactate metabolism in Huntington's disease is dependent on GLUT3 expression. AB - AIMS: Huntington's disease (HD) is a neurodegenerative disorder characterized by progressive abnormalities in cognitive function, mental state, and motor control. HD is characterized by a failure in brain energy metabolism. It has been proposed that monocarboxylates, such as lactate, support brain activity. During neuronal synaptic activity, ascorbic acid released from glial cells stimulates lactate and inhibits glucose transport. The aim of this study was to evaluate the expression and function of monocarboxylate transporters (MCTs) in two HD models. METHODS: Using immunofluorescence, qPCR, and Western blot analyses, we explored mRNA and protein levels of MCTs in the striatum of R6/2 animals and HdhQ7/111 cells. We also evaluated MCT function in HdhQ7/111 cells using radioactive tracers and the fluorescent lactate sensor Laconic. RESULTS: We found no significant differences in the mRNA or protein levels of neuronal MCTs. Functional analyses revealed that neuronal MCT2 had a high catalytic efficiency in HD cells. Ascorbic acid did not stimulate lactate uptake in HD cells. Ascorbic acid was also unable to inhibit glucose transport in HD cells because they exhibit decreased expression of the neuronal glucose transporter GLUT3. CONCLUSION: We demonstrate that stimulation of lactate uptake by ascorbic acid is a consequence of inhibiting glucose transport. Supporting this, lactate transport stimulation by ascorbic acid in HD cells was completely restored by overexpressing GLUT3. Therefore, alterations in GLUT3 expression could be responsible for inefficient use of lactate in HD neurons, contributing to the metabolic failure observed in HD. PMID- 29582589 TI - Nafion/Titanium Dioxide-Coated Lithium Anode for Stable Lithium-Sulfur Batteries. AB - Lithium-sulfur (Li-S) batteries have shown great potential as high energy-storage devices. However, the stability of the Li metal anode is still a major concern. This is due to the formation of lithium dendrites and severe side reactions with polysulfide intermediates. We herein develop an anode protection method by coating a Nafion/TiO2 composite layer on the Li anode to solve these problems. In this architecture, Nafion suppresses the growth of Li dendrites, protects the Li anode, and prevents side reactions between polysulfides and the Li anode. Moreover, doped TiO2 further improves the ionic conductivity and mechanical properties of the Nafion membrane. Li-S batteries with a Nafion/TiO2 -coated Li anode exhibit better cycling stability (776 mA h g-1 after 100 cycles at 0.2 C, 1 C=1672 mA g-1 ) and higher rate performance (787 mA h g-1 at 2 C) than those with a pristine Li anode. This work provides an alternative way to construct stable Li anodes for high-performance Li-S batteries. PMID- 29582590 TI - Gap analysis of Mycoplasma bovis disease, diagnosis and control: An aid to identify future development requirements. AB - There is a worldwide problem of disease caused by Mycoplasma (M.) bovis in cattle; it has a significant detrimental economic and animal welfare impact on cattle rearing. Infection can manifest as a plethora of clinical signs including mastitis, pneumonia, arthritis, keratoconjunctivitis, otitis media and genital disorders that may result in infertility and abortion. Current diagnosis and control information are reviewed and analysed to identify gaps in knowledge of the causative organism in respect of the disease pathology, diagnosis and control methods. The main considerations are as follows: no vaccines are commercially available; antimicrobial resistance is increasing; diagnostic and antimicrobial sensitivity testing needs to be improved; and a pen-side test would facilitate more rapid diagnosis and implementation of treatment with antimicrobials. More data on host susceptibility, stress factors, immune response and infectious dose levels are required. The impact of asymptomatic carriers, M. bovis survival in the environment and the role of wildlife in transmitting the disease also needs investigation. To facilitate development of vaccines, further analysis of more M. bovis genomes, its pathogenic mechanisms, including variable surface proteins, is required, along with reproducible disease models.

PMID- 29582592 TI - Simultaneous in vivo confocal reflectance and two-photon retinal ganglion cell imaging based on a hollow core fiber platform. AB - We have developed a compact hollow core fiber (HCF)-based imaging platform capable of simultaneous in vivo confocal reflectance and two-photon imaging through the mouse pupil. We demonstrate the performance of this platform by imaging retinal ganglion cells (RGCs) in which the fluorophores YFP and GCaMP3 are expressed in Thy1-YFP-16 and Thy1-GCaMP3 transgenic mice, respectively. Confocal reflectance images of the mouse retina served as a reference for the simultaneous acquisition of the two-photon signals that clearly showed RGCs with single-cell resolution. The use of an HCF platform makes the system compact with future application in the longitudinal investigation into the structure and function of healthy and diseased RGCs. PMID- 29582593 TI - [Preparation of hydrophilic polymer brushes magnetic microspheres by surface initiated for magnetic dispersive solid phase extraction of tetracycline antibiotic residues from honey]. AB - Activators regenerated by electron transfer-atom transfer radical polymerization (ARGET-ATRP) was applied to the continuous grafting of polybasic polymers and poly(ethylene glycol) (PEG) brushes on the surface of the magnetic microspheres (MMs). At first, the MMs were coated with silica gel, modified by amino group, and then 2-bromoisobutyryl bromide was grafted on the surface of MMs. After that, the hydrophilic polymer brushes magnetic microspheres (HMMs) were prepared by polymerization on the surface of the MMs. HMMs were characterized by transmission electron microscope (TEM) and Fourier transform-infrared (FT-IR) spectrometer. The adsorption performance to protein was studied. The results demonstrated that HMMs have the relatively uniform particle size, good dispersity and excellent protein resistance properties. Tetracycline antibiotics (TCs, tetracycline hydrochloride, chlortetracycline hydrochloride and doxycycline hydrochloride) in honey samples were determined by magnetic dispersion solid phase extraction (MDSPE) using the prepared HMMs and high performance liquid chromatography (HPLC). The average recoveries were obtained in the range of 85.8%-94.5%. The limits of detection (LODs) and limits of quantification (LOQs) of the proposed method were in the ranges of 1.92-2.56 MUg/kg and 6.40-8.53 MUg/kg, respectively. The proposed method was successfully applied to fast clean-up and enrichment of the TCs residues in honey.

AB - A method for the separation and determination of lactose and sucrose using high performance liquid chromatography-refractive index (HPLC-RI) detection base on the prepared amino-bonded silica gel chromatographic stationary phase was established. The method was accorded to the content determination method in Pharmacopoeia of the People's Republic of China (2015). Then, a series of chromatographic behaviors of lactose and sucrose such as the retention times, resolutions and peak area stabilities were investigated on three different types of amino-bonded silica columns (300 mm*4.6 mm, 5 MUm). The mobile phase was acetonitrile-water (70:30, v/v) with isocratic elution, the flow rate was 1.0 mL/min and the injection volume was 10 MUL. The resolution of lactose and sucrose was 3.03 by isopropyl side chain protected amino column, and the peak shape of each target compound was good. The relative standard deviation (RSD) of peak area of lactose was 1.14%, less than 2.0% prescribed in the Pharmacopoeia of the People's Republic of China (2015). Therefore, this method meets the requirements of lactose content determination, and is suitable as the quality control method in the above mentioned Pharmacopoeia. PMID- 29582587 TI - Disrupted striatal neuron inputs and outputs in Huntington's disease. AB - Huntington's disease (HD) is a hereditary progressive neurodegenerative disorder caused by a CAG repeat expansion in the gene coding for the protein huntingtin, resulting in a pathogenic expansion of the polyglutamine tract in the N-terminus of this protein. The HD pathology resulting from the mutation is most prominent in the striatal part of the basal ganglia, and progressive differential dysfunction and loss of striatal projection neurons and interneurons account for the progression of motor deficits seen in this disease. The present review summarizes current understanding regarding the progression in striatal neuron dysfunction and loss, based on studies both in human HD victims and in genetic mouse models of HD. We review evidence on early loss of inputs to striatum from cortex and thalamus, which may be the basis of the mild premanifest bradykinesia in HD, as well as on the subsequent loss of indirect pathway striatal projection neurons and their outputs to the external pallidal segment, which appears to be the basis of the chorea seen in early symptomatic HD. Later loss of direct pathway striatal projection neurons and their output to the internal pallidal segment account for the severe akinesia seen late in HD. Loss of parvalbuminergic striatal interneurons may contribute to the late dystonia and rigidity. PMID- 29582595 TI - [Preparation of phenyl-modified silica nanoflake fibers and the solid-phase microextraction of polycyclic aromatic hydrocarbons]. AB - A novel silica-based solid-phase microextraction (SPME) fiber was successfully fabricated by the immobilization of silica nanoflakes (SiO2NFs) onto the hydrothermally treated nickel-titanium alloy (NiTi) wire using sol-gel method, followed by self-assembled surface modification of phenyltrichlorosilane. The extraction performance of the fabricated fiber was evaluated using typical aromatic compounds in direct-immersion mode of SPME. The fiber exhibited the high extraction capability and good extraction selectivity for polycyclic aromatic hydrocarbons (PAHs) in water samples. The influences of stirring rate, extraction temperature, extraction time and ionic strength on the extraction efficiencies were optimized coupled to HPLC with UV detection. Under the optimized conditions, the five PAHs presented good linearity in the certain mass concentration ranges with correlation coefficients (r) greater than 0.999, and LODs ranged from 0.013 to 0.108 MUg/L. The intra-day and inter-day RSDs were from 4.1% to 5.9% and 4.8% to 6.8% for the PAHs at the spiked level of 50 MUg/L with the single fiber, respectively. The recoveries of the five PAHs in real water samples spiked at 10 MUg/L and 30 MUg/L ranged from 90.8% to 105.7% and 93.6% to 103.1%, respectively. Moreover, the phenyl-modified SiO2NFs coated NiTi fiber has high stability and good preparation reproducibility. The developed method is suitable for the concentration and determination of the target PAHs in environmental water samples. PMID- 29582596 TI - [Two-dimensional liquid chromatography separation and high resolution mass spectrometry analysis for proteome of rice leaves based on different extraction methods]. AB - A two-dimensional liquid chromatography (2D LC) system was developed to separate proteins from rice leaves, which was extracted by phenol method, followed by the analysis with linear trap quadrupole orbitrap mass spectrometry (LTQ/Orbitrap MS). After proteins were extracted with phenol method, the enzymolytic peptides were separated by offline two-dimensional RP-RP system and detected by LTQ/Orbitrap MS, yielding 2712 proteins. Liquid chromatography separation system (1D LC and 2D LC) and protein extraction methods (phenol method, sodium dodecyl sulfate method (SDS method) and trichloroacetic acid/acetone method (TCA/acetone method)) were compared. Proteins identified by 2D LC were 2712, 2415 and 1914 with the above three extraction methods, respectively. The proteins were 2.7 fold, 2.5-fold and 1.9-fold the number of proteins identified by 1D LC respectively. And in terms of 2D LC, the proteins identified by phenol method were 297 and 798 more than SDS method and TCA/acetone method, respectively. Some proteins with extreme properties, such as very acidic or basic protein and high relative molecular mass proteins, were only identified in phenol method. Furthermore, proteins, which were extracted by different extraction methods and separated by 2D LC, were classified according to biological functions. It was found that protein functions by the three extraction methods were complementary. However, phenol method had the most variety of functions. The method provides technological support for rice proteomics and reference for research techniques of other crop proteomics.

The extraction solvents, types of SPE cartridges and eluents were optimized by comparing the recoveries under different conditions. The results showed that the detector response of each target compound was linear in corresponding mass concentration ranges with the correlation coefficients (r2) >= 0.9992. The limits of detection (LODs) and the limits of quantification (LOQs) of the three analytes were 1.48-13.61 MUg/kg and 5.96-45.67 MUg/kg, respectively. The recoveries of the three analytes were 65.02% 118.33% spiked at low, medium and high levels. The relative standard deviations (RSDs) were no more than 13.41%. The method is reliable, easy, and has a better purification effect. The method can be applied to the routine analysis of metformin hydrochloride and its relative substances melamine and dicyandiamide in different preparations of metformin hydrochloride.

AB - High performance liquid chromatography (HPLC) was used for the separation and quantification of the low molecular-mass organic acids in the root exudates of Cr hyperaccumulator Leersia hexandra Swartz. Eight organic acids, oxalic, tartaric, formic, malic, lactic, acetic, maleic and citric acids, were separated on an XSelect HSS T3 column (250 mm*4.6 mm, 5 MUm) within 13 min with the mobile phase of 40 mmol/L potassium dihydrogen phosphate-phosphorous acid at pH 2.40, a flow rate of 1.0 mL/min, a detection wavelength of 205 nm and a column temperature of 25C. This is a simple and highly sensitive method for the separation of the eight organic acids with well-shaped peaks. The limits of detection (LODs) for the eight acids ranged from 0.12 mg/L to 12.32 mg/L. Under the optimized conditions, tartaric, malic, lactic, maleic and citric acids in the root exudates were detected with high linearities, acceptable recoveries and excellent precisions. The contents of these acids calculated in the root exudates were (130.90+/-1.44) MUg/g (root dry weight (DW)) for tartaric acid, (1031.34+/-4.38) MUg/g (root DW) for malic acid, (65.54+/-1.01) MUg/g (root DW) for lactic acid, (0.96000+/ 0.00367) MUg/g (root DW) for maleic acid and (201.50+/-1.13) MUg/g (root DW) for citric acid. The proposed HPLC method is quite suitable for the simultaneous determination of organic acids in the root exudates of Leersia hexandra Swartz, and can be used in other plant root exudates as well.

AB - In order to develop a fast investigation method for phthalate esters (PAEs) from vegetable oils, a gas-liquid micro-extraction (GLME) technique that combined with GC-MS was established. A vegetable oil sample (0.1 g) was directly added into the GLME device. The integrated process of extraction, clean-up, and concentration of PAEs was completed within 5 min. Internal standard method was applied to ensure the accuracy of the results. Soybean oil, blend oil, olive oil, and sesame oil were spiked with 200 MUg/kg of a mixed 15 PAEs standard, and the ranges of the recoveries and RSDs were between 60.0% to 112.3% and 0.9% to 28.4%, respectively. Compared with some traditional sample pretreatment methods such as liquid-liquid extraction, liquid-liquid micro-extraction, gel permeation chromatography, this method is simple and fast, with high accuracy, good repeatability and low matrix effect. This study verified the suitability of the GLME method for field detection of food products in food safety sector and exhibits great significance for the completion of food safety system in China.

AB - The enantiomeric separation of unmodified D,L-isoleucine was achieved in citric acid-zinc(II) medium by capillary electrophoresis (CE) with contactless conductivity detector (C4D). In the conventional chiral separation methods of amino acid, a chiral complex used as the chiral selector was added into the eluent in order to yield a chiral environment. However, in this study a non chiral solution, i. e. 2.8 mmol/L NaOH+0.8 mmol/L citric acid+2.0 mmol/L zinc acetate was used as the running buffer, and the citric acid-zinc(II) acted the role of a chiral selector. Under the optimum experimental conditions:uncoated fused-silica capillary (45 cm*50 MUm, Leff=40 cm), separation voltage of +13 kV, electrokinetic injection of 11 kV*8 s, the enantiomers of D,L-isoleucine were baseline separated within 8 min with the resolutions (Rs) of 2.0. The calibration curve of each enantiomer showed good linearity in the range from 1.0 mg/L to 20 mg/L, with the limits of detection of 0.40 mg/L. The intra-and inter-day precisions were examined. The RSDs of peak area and migration time were found to be below 5.0% and 2.5% (n=6), respectively, indicating good repeatability (intra day) and reproducibility (inter-day) of the method. Interference experiment was also tested. As a result, other common amino acids did not interfere with the detection. The proposed method provided a potential new way to further investigate the enantioseparation of unmodified or native amino acids.

AB - A monolithic fiber of poly(butyl methacrylate-ethylene glycol dimethacrylate)[poly(BMA-EDMA)] was prepared using deep eutectic solvent (DES) of choline chloride-ethanediol as a porogen. The prepared fibers were applied to direct extraction of three polycyclic aromatic hydrocarbons (PAHs) in lake water samples by solid phase microextraction (SPME). The extracts were determined by ultra performance liquid chromatography (UPLC). The fiber without DES was prepared at the same time. Both fibers (with and without DES) were compared with a commercial polydimethylsiloxane (PDMS) fiber. The highest extraction efficiency was clearly obtained with poly(BMA-EDMA) fiber. The extraction time, extraction solvent, desorption time, desorption solvent, and ionic strength were optimized. Under the optimum conditions, the linear ranges for the three PAHs (naphthalene, biphenyl, and phenanthrene) were 0.1-6.0 mg/L (r >= 0.9903). The limits of detection (LODs) of the three PAHs were in the range of 2.1-4.9 MUg/L. The recoveries of the three PAHs spiked in lake water samples were 86.4%-111.3% with relative standard deviations (RSDs, n=6) of 11.2%-15.1%. This method is simple, stable, and inexpensive, and can be used for the determination of the PAHs in lake water samples.

AB - The heterogeneity of Ralstonia solanacearum avirulent espD-mutant, virulent wildtype strain FJAT-91 and spontaneous avirulent strain FJAT-1458 were compared and analyzed by using high performance ion-exchange chromatography (HPIEC). Their colony and cell morphologies were observed, and the contents of their extracellular polysaccharides (EPS) were determined. The results showed that the colony and cell morphologies of FJAT-91 ?epsD were different from the original strain FJAT-91, but were similar to the spontaneous avirulent strain FJAT-1458. The EPS content of FJAT-91 ?epsD was (12.64+/-1.46) MUg/mL, which was much lower than FJAT-91 with (30.49+/-2.97) MUg/mL. The strain FJAT-91 were separated into single peak of P3 at the retention time of 6.04 min, and FJAT-91 ?epsD had two peaks (P1 and P2) at the retention times of 0.59 min and 4.62 min, respectively. FJAT-1458 formed single peak of P1 at the retention time of 0.59 min. Then, the bacteria eluents from different chromatographic peaks were collected and their pathogenicities were detected with bioassay test using potted tomatoes in the greenhouse. The results showed that the tomato plants began to wilt 4 d after inoculation of strain FJAT-91-P3 eluted from P3, and the disease incidence reached 100% at 10 d post inoculation. The strain FJAT-91 ?epsD-P2 eluted from P2 caused tomato plants wilting 9 d after inoculation, and the disease incidence reached 100% at 20 d. During 20 d of observation, none of tomato plants caused wilting while inoculation with FJAT-1458-P1 and FJAT-91 ?epsD-P1 eluted from P1 of FJAT-1458 and FJAT-91 ?epsD, respectively. In this paper, the morphologies, EPS contents and chromatographic behaviors of FJAT-91, FJAT-91 ?epsD and FJAT 1458 were compared, which would provide theoretical basis for using FJAT-91 ?epsD to control bacterial wilt disease.

AB - A method was established for the simultaneous separation and determination of one organophosphorus and three carbamate insecticide residues in food and water samples by solid phase extraction (SPE) followed by analysis using a home-made capillary liquid chromatogram. Various parameters possibly affecting the efficiencies of capillary liquid chromatography (CLC) and SPE were investigated in detail, such as type of SPE column, pH value of samples, type and volume of elution solvent, flow rate of loading sample, salt effect, loading volume, detection wavelength, and type and ratio of mobile phases. Under the optimized experimental conditions, the four insecticides were separated completely within 6 min. The limits of detection and limits of quantification were 0.35-1.20 MUg/kg and 1.17-4.00 MUg/kg, respectively. Satisfactory recoveries of the SPE-CLC method were achieved for spiked food samples of tomato, cucumber and apple ranging from 72.41% to 107.15% with the relative standard deviations (RSDs) no more than 8.12%, and for spiked tap/lake water samples ranging from 71.45% to 109.25% with the RSDs no more than 9.28%. The method can meet the requirements for multi residue analysis of insecticides.

AB - A method for the determination of 37 fatty acids in natural cream and artificial cream was developed by comprehensive two-dimensional gas chromatography-mass spectrometry (GC*GC-MS). The samples were extracted with toluene and acetyl chloride-methanol (1:9,v/v) solution was added to the extract for fat esterification. Finally, the fatty acids were analyzed by GC*GC-MS. The GC conditions were as follows:a DB-5 column (30 m*0.25 mm*0.25 MUm) was set as the 1st dimensional column and a BPX-50 column (2.5 m*0.1 mm*0.25 MUm) was the 2nd dimensional column. The primary oven temperature was programmed from 50C (held for 2 min) to 180C at a rate of 20C/min, followed by an increase to 250C at 2.5C/min, then raised up to 300C (held for 5 min) at 3C/min. The ion source temperature was 200C with auxiliary temperature of 300C in scan mode. All fatty acids were separated effectively and determined accurately while the modulation period was 5s and the scan range of MS was m/z 40-385. This procedure was applied to analyze the fatty acids in commercial natural cream and artificial cream from Chinese markets, among which we found the characteristic components in different kinds of samples. Compared with gas chromatography-flame ionization detector (GC FID), GC*GC-MS method was more sensitive and more components of fatty acids were detected. Conclusively, this work suggests a new technical approach in analyzing fatty acids in natural cream and artificial cream, which is meaningful to ensure the quality identification and safety of natural cream.

The results showed that the 16 PAHs had good linearities in the range of 0.01-1.00 mg/L with the correlation coefficients (R) greater than 0.997. The spiked recoveries of the 16 PAHs were in the range of 75.8%-97.8%, and the relative standard deviations (RSDs) were less than 10%. The method detection limits (MDLs) of the 16 PAHs ranged from 0.048-0.234 MUg/kg with 20.0 g sampling weight. This method is suitable for the determination of trace PAHs in marine sediments. PMID- 29582614 TI - [Rapid resolving algorithm of gas chromatographic overlapping peaks based on the asymptotic expansion of integration]. AB - A novel algorithm, called asymptotic expansion of integration, is suggested to resolve gas chromatographic overlapping peaks. There are three steps for the algorithm. First, a valley peak or a shoulder peak is separated into two domains, and an integral equation on a subdivision and an algebraic equation on the overlapping peak domain are listed. Secondly, areas needed in two equations, are computed by a numerical integral method, then the integral equation is expended to an algebraic equation by the asymptotic formula of integration. At last, combing two equations with constraint equations of peak heights, we got a nonlinear algebraic set. The equation set can be solved rapidly by Gauss-Seidel iteration, and the maximum number of iterations is not more than 20 times. The simulation and experimental results showed that height and area errors of resolving peaks are quite small, the maximum error of area is less than 6.44%, and that of the height is about 6.80%. Because of the high accuracy and computational efficiency, the algorithm can be used in decomposition of gas chromatographic overlapping peaks and online real-time processing of general chromatographic overlapping peaks.

AB - Capillary electrophoresis (CE) has been used to establish the analytical method of interaction between pentadecafluorooctanoic acid (PFOA) and human serum albumin (HSA). Under the physiological conditions, the interaction model of PFOA and HSA were constructed. Mobility method, plug-plug kinetic (PPK) method and simplified Hummel-Dreyer method were used to determine the interaction between derivatives and HSA. Non-linear regression, Scatchard equation and Klotz equation were adopted to obtain the interaction parameters. The results showed that all the three methods can be used to analyze the interaction of PFOA-HSA system. According to the interaction parameters, the most suitable CE method is simplified Hummel-Dreyer method while the most suitable theoretical equation is non-linear regression. The binding parameters indicated that the interaction of PFOA-HSA system has only one type of binding sites and the binding is stable. The research results have illustrated the interaction between HSA and PFOA, and provided a beneficial reference for in-depth research of the toxic mechanism of PFOA.

PMID- 29582617 TI - Real world use of biological drugs in patients with psoriasis/psoriatic arthritis: a retrospective, population-based study from Southern Italy in the years 2010-2014. AB - BACKGROUND: Biological drugs, such as infliximab, etanercept, adalimumab, ustekinumab, golimumab and certolizumab are third-line therapy for psoriasis (PsO) and psoriatic arthritis (PsA), but they may be used at earlier stage in severe forms. This study investigated the pattern of use and costs of biological drugs for PsO/PsA in a large population from Southern Italy during the years 2010 2014. METHODS: This was a retrospective, population-based, drug-utilization study, using healthcare administrative databases of the Local Health Unit and two hospitals of Messina Province (Sicily) in the years 2010-2014. Incident users of adalimumab, ustekinumab, infliximab, etanercept and golimumab for PsO/PsA were characterized. Yearly prevalence of use and costs, as well as time to treatment discontinuation and switch were assessed. RESULTS: During the study period, 517 patients received at least one study drugs prescription for PsO/PsA and 304 (58.8%) were incident users, mostly treated with adalimumab (33.6%). Incident users were mostly males (59.8%), with a median age of 49 years. Prevalence of biological drugs users in PsO/PsA increased from 4.3 to 6.9 per 10,000 inhabitants from 2011 to 2014. Pharmaceutical expenditure of the study drugs almost doubled (from 2.6 to 4.7 million euros during 5 observation years). During the first year of treatment, discontinuation occurred in 31.8% of incident users and switch was not infrequent (7.4%). CONCLUSIONS: Prevalence of use and costs of biological drugs for PsO/PsA substantially increased in recent years in a large population of Southern Italy. Larger uptake of lowest cost biological drugs, and biosimilars whenever available, may help access to the most innovative drugs. PMID- 29582618 TI - Comparison of clinical effects, trough and peak levels between branded and generic formulation of Cyclosporine in stable psoriatic patients. AB - BACKGROUND: Cyclosporine A (CyA) is a drug for moderate-to-severe psoriasis. Recently, a generic formulation has been approved as bioequivalent to the branded one. The guidelines for the bioequivalence for critical-dose drugs with a narrow therapeutic range, such as CyA, are questionable. Therefore, it is important to assess the clinical outcome and the pharmacokinetics of different formulations in various patient groups. The current literature lacks of this information in dermatology. The primary objective of this prospective study is to investigate the clinical equivalence (in terms of maintenance of clinical effect) between the generic formulation of CyA and its branded one in patients with psoriasis. A secondary objective is to analyze their trough (C0) and peak levels (C2). METHODS: Twenty patients with stable psoriasis under treatment with the branded CyA were monitored in terms of clinical efficacy (Psoriasis Area Severity Index- PASI), safety (laboratory values), and their pharmacokinetics utilizing trough (C0) and peak plasma concentration (C2). The same patients were subsequently shifted to the generic formulation for comparison. RESULTS: In our sample the efficacy of the two formulations was equal in most cases (p=0.863). A non significant difference between the C0 and C2 of the branded CyA compared to the generic one emerged (respectively p=0.738 and p=0.695). CONCLUSIONS: The branded and the generic formulations of CyA seem to be not only bioequivalent, but also comparable in terms of clinical efficacy in patients with psoriasis. However, larger samples are required to confirm these findings. PMID- 29582619 TI - Oral Echinacea exerts complete clearing of multiple facial molluscum contagiosum in a young black patient. PMID- 29582620 TI - Is HERV-K and HERV-W expression regulated by mir-155 in Sezary syndrome? AB - BACKGROUND: According to the latest update, 2578 unique mature miRNAs are currently annotated in the human genome and participate in the regulation of multiple events, such as cellular proliferation or apoptosis. A previous study analyzing global miRNA expression patterns in GH cells (high HERV-K versus low) showed that two miRNAs (miR-663 and miR-638) are differentially regulated and exhibit expression parallel to that of HERV-K. The aim of this study was to evaluate HERV-K and -W pol gene and mir-155 expression in SS patients and possible relationship between them. METHODS: The comparison between SS patients and healthy donor showed a significant difference in terms of mir-155 expression p=0.0003 as previously reported by our groups. RESULTS: We demonstrated that HERV K and -W pol gene expression was significantly higher in SS patients vs healthy donor as previously reported by our groups. Our correlation data suggest that miR 155 are not directly involved in regulating the HERVs. CONCLUSIONS: Furthermore, further studies including other cohorts of pathology with mir-155 and HERVs involvement such as inflammatory diseases are needed to investigate the role of mir-155 in the cross-activations of HERVs.

AB - BACKGROUND: To assess the efficacy and safety of intramyocardial autologous bone marrow mononuclear stem cells (BMMNC) grafting combined with coronary artery bypass grafting (CABG) on ventricular remodeling and global and regional wall motion after acute transmural myocardial infarction (AMI). METHODS: Randomized controlled trial including 20 patients with non-revascularized transmural AMI, left ventricular ejection fraction (LVEF) lower than 50% and surgical indication for CABG. The stem cell group was treated with BMMNC grafting by direct intramyocardial injection between the 10th and 15th days after AMI (subacute phase) combined with CABG under cardiopulmonary bypass; the control group was only treated with CABG. Magnetic resonance imaging with gadolinium and stress echocardiography were performed presurgery and 9 months postsurgery. RESULTS: Seventeen patients completed the follow-up. The baseline characteristics of both groups were homogeneous. No significant differences were found in the increase in LVEF (control: 6.99+/-4.60, cells: 7.47+/-6.61, P=0.876) or in the decrease in global (control: 0.28+/-0.39, cells: 0.22+/-0.28, P=0.759) or regional (control: 0.52+/-0.38, cells: 0.74+/-0.60, P=0.415) wall motion indices between the control and stem cell groups of AMI patients. No differences were found in the recovered non-viable segments (control: 1.29+/-1.11, cells: 2.50+/-1.41, P=0.091) or in the decrease in end-diastolic (control: 14.05+/-19.72, cells: 18.40+/-29.89, P=0.725) or end-systolic (control: 15.42+/-13.93, cells: 23.06+/-25.03, P=0.442) volumes. No complications from stem cell grafting were observed. CONCLUSIONS: The results from our study reported herein suggest that intramyocardial BMMNC administration during CABG in patients with AMI causes no medium- to long-term improvement in ventricular remodeling.

Methods: We studied829 patients (538 men, 291 women) with NSCLC who underwent complete pulmonary resection in 9 hospitals. Eventdynamics with the use of life-table methods were evaluated, and only first events (distant metastases or local recurrence)were considered. The effects of sex, histological type, pathological stage, and smoking history were studied. Result:The resulting smoothed hazard rate curves indicated that the recurrence risk pattern definitely correlated with sex, witha sharp peak in the first year in men and a broad peak during the first 2 to 3 years in women. These findings were alsoconfirmed by analyses according to pathological stage, histological type, and smoking history. Conclusion: The peaktimes of recurrence differed considerably between men and women. The delayed time of peak recurrence in women,associated with a longer disease-free interval within subsets of patients with similar disease stage, histological type,and smoking status, might account for the better survival in women.

Alcohol detoxification is governed by ADH1B,ALDH2, GSTM1 and GSTT1 genes that encode functional enzymes which are coordinated with each other to removehighly toxic metabolites i.e. acetaldehyde as well as reactive oxygen species generated through detoxification processes.Some communities in the population appears to be at greater risk for development of the liver cancer due to geneticpredispositions. Methods: The aim of this study was to screen the arcadian population of central India in order toinvestigate and compare the genotype distribution and allele frequencies of alcohol metabolizing genes (ADH1B,ALDH2, GSTM1 and GSTT1) in both alcoholic (N=121) and control (N=145) healthy subjects. The gene polymorphismanalysis was conducted using PCR and RFLP methods. Results: The allele frequency of ALDH2 *1 was 0.79 and ofALDH2*2 was 0.21 (OR:1.12; CI (95%): 0.74-1.71). The null allele frequency for GSTM1 was 0.28 (OR:0.85; CI(95%): 0.50-1.46) and for GSTT1 was 0.20 (OR:1.93; CI (95%): 1.05 3.55). No gene polymorphism for ADH1B wasnot observed. The total prevalence of polymorphisms was 3.38% for ALDH2, GSTM1 and GSTT1. Conclusion: Theresults of this study suggested that individuals of the Central India population under study are at risk for liver disordersdue to ALDH2, GSTM1 and GSTT1 gene polymorphisms. This results may have significance for prevention of alcoholdependence, alcoholic liver disorders and the likelihood of liver cancer. PMID- 29582628 TI - Self-Confidence and Quality of Life in Women Undergoing Treatment for Breast Cancer AB - Introduction: Quality of life is an important topic in the study of chronic diseases, especially cancer which can havea major effect on patient self confidence. This study was conducted to determine quality of life and its relationship withself-confidence in women undergoing treatment for breast cancer. Methods: This cross-sectional, descriptive, analyticalstudy was conducted in 2016 on 166 women with breast cancer undergoing treatment at Ghazi, Al-Zahra, Internationaland/or Shams hospitals in Tabriz. The subjects were selected through convenience sampling. A personal-demographicquestionnaire, the Cancer Quality of Life Questionnaire (QLQ-C30), and the Rosenberg Self-Esteem Scale (RSES) werecompleted for each patient. The data obtained were analyzed using independent t-tests, one-way ANOVA, multivariatelinear regression and Pearson's correlation coefficients. Findings: The mean total score of quality of life was 59.1+/ 17.4,ranging from 0 to 100. The highest mean score was obtained in the cognitive subscale (74.9+/-23.8) and the lowest in theemotional subscale (51.4+/-21.1). The mean score for self-confidence was 0.3 with a standard deviation of 0.1, rangingfrom -1 to +1. There was a significant positive relationship between self confidence and quality of life, except in threesymptom subscales for diarrhea, constipation and loss of appetite (P<0.05). Self-confidence, disease duration, lifestyle,marital satisfaction and caregiver status were among the predictors of quality of life. Discussion: Given the significantrelationship between quality of life and self-confidence, health care providers may need to pay special attention towomen undergoing treatment for breast cancer and perform timely measures to maintain their belief in themselves. PMID- 29582629 TI - Urinary Metabolomic Profiling in Chronic Hepatitis B Viral Infection Using Gas Chromatography/Mass Spectrometry AB - Background: Chronic hepatitis B (CHB) can lead to cirrhosis and hepatocellular carcinoma. The metabolomicprofiling has been shown to be associated with pathogenic mechanisms in many medical conditions includingCHB. The purpose of this study was to investigate the urine metabolomic profiles in CHB patients by gaschromatography/mass spectrometry (GC/MS). Methods: Urine samples were collected from CHB patients (n = 20)and normal control subjects (n = 20). Metabolite profiles were assessed using GC/MS in conjunction with multivariatestatistical analysis, in order to identify biomarker metabolites. Pathway analysis was performed by MetaboAnalyst3.0 and KEGG database.Results: Twelve out of 377 metabolites were shown to be significantly different between theCHB and normal control groups (p < 0.05). These include palmitic acid, stearic acid, oleic acid, benzoic acid, butanoicacid, cholesterol, glycine, 3-heptanone, 4-heptanone, hexanal, 1-tetradecanol and naphthalene. Multivariate statisticalanalysis constructed using these expressed metabolites showed CHB patients can be discriminated from healthy controlswith high sensitivity (95%) and specificity (85%). All the metabolic perturbations in this disease are associated withpathways of fatty acid, amino acid, bile acid and gut microbial metabolism. Conclusion: CHB patients have a specificurinary metabolomic profile. The abnormalities of fatty acid, amino acid, bile acid, and gut microbial metabolism leadto the development of disease progression. GC/MS-based assay is a promising tool for the metabolomic study in CHB. PMID- 29582630 TI - Comparison of Survival Models for Analyzing Prognostic Factors in Gastric Cancer Patients AB - Objective: There are a number of models for determining risk factors for survival of patients with gastric cancer.This study was conducted to select the model showing the best fit with available data. Methods: Cox regression andparametric models (Exponential, Weibull, Gompertz, Log normal, Log logistic and Generalized Gamma) were utilized inunadjusted and adjusted forms to detect factors influencing mortality of patients. Comparisons were made with AkaikeInformation Criterion (AIC) by using STATA 13 and R 3.1.3 softwares. Results: The results of this study indicated thatall parametric models outperform the Cox regression model. The Log normal, Log logistic and Generalized Gammaprovided the best performance in terms of AIC values (179.2, 179.4 and 181.1, respectively). On unadjusted analysis,the results of the Cox regression and parametric models indicated stage, grade, largest diameter of metastatic nest,largest diameter of LM, number of involved lymph nodes and the largest ratio of metastatic nests to lymph nodes,to be variables influencing the survival of patients with gastric cancer. On adjusted analysis, according to the best model(log normal), grade was found as the significant variable. Conclusion: The results suggested that all parametric modelsoutperform the Cox model. The log normal model provides the best fit and is a good substitute for Cox regression. PMID- 29582631 TI - Effect of an Educational Intervention Based on Protection Motivation Theory on Preventing Cervical Cancer amongMarginalized Women in West Iran AB - Objective: This study aimed to determine the effectiveness of an educational intervention to prevent cervical canceramong marginalized Iranianwomen based on the Protection Motivation Theory (PMT) as a theoretical framework.Methods: This quasi-experimental study was carried out on 143 women of Kermanshah City in western Iran during2017. Participants were recruited through cluster and simple random sampling and randomly divided into experimental(n=72) and control groups (n=71). All completed a self-administered questionnaire including PMT constructs anddemographic variables. An intervention over six sessions was then applied to the experimental group. Reassessmentwas conducted three months after the intervention, with data was analyzed with SPSS-16 using chi-square, McNemar,paired T- and independent T-tests. Results: The mean scores for the constructs of PMT, and cervical cancer screeningbehavior showed no significant differences between the two groups before the intervention (P>0.05). The educationalmanipulation had significant effects on the experimental groups' average response for perceived vulnerability, perceivedseverity, perceived reward, self-efficacy, response efficacy, response cost and protection motivation (all p < 0.001).Also, the prevalence of regular Pap smear testing and referral to health centers were significantly increased after 3months in the experimental (P=0.048), but notthe control group (P>0.05). Conclusions: The results show that applyingan educational intervention based on PMT might help prevent cervical cancer and improve regular Pap smear testing. PMID- 29582633 TI - Cancer-Related Pain: Prevalence, Severity and Management in a Tertiary Care Center in the Middle East AB - Background: Despite pain awareness and the development of treatment guidelines, cancer-related pain assessmentand management remain suboptimal. Our objectives were to estimate the prevalence and severity of pain and itsinterference with daily activities, and evaluate adequacy of treatment in cancer patients in Lebanon. Methods: Atotal of 400 cancer patients aged 18 and above were interviewed at the American University of Beirut Medical Centersurgical and medical oncology floors, outpatient clinics and chemotherapy units from March 2016-February 2017. Thesubjects covered were socio-demographics, clinical data, and presence of pain in the past month with use of the BriefPain Inventory questionnaire. Descriptive statistics were conducted using t-test, chi-square and Fischer's exact tests.Pearson's correlation coefficients were used to examine relationships between pain severity and pain interference.Logistic regression was employed to determine risk factors for pain. Results: The majority of participants were Lebanese(76.0%), females (62.7%), married (80.2%), of Muslim faith (64.2%), of urban residence (85.8%), and with insuranceplans (81.3%). Most had breast cancer (38.8%), were stage 4 (52.7%) and underwent a combination of surgery andsystemic therapy (55.1%). The prevalence of pain in the past month was 29.8%. Among patients with pain, the highestproportion had moderate pain (37.8%) and around 46% received inadequate treatment. Conclusion: More awarenessabout cancer-related pain is needed to improve pain management and encourage referral to palliative care and painspecialists early-on in diagnosis of disease. PMID- 29582632 TI - Accuracy of Specimen Radiography in Assessing Complete Local Excision with Breast Conservation Surgery AB - Objective: The aim of this study was to evaluate the accuracy of "X- ray examination of surgicallyresected specimen'' in assessing complete local excision (CLE). Materials and Methods: In this retrospective crosssectional study, data were collected for all female breast cancer cases who underwent breast-conserving surgery afterneedle localization of mammographically visible disease. Males, patients with mammographically invisible diseaseand cases with benign or inconclusive histopathology, those undergoing modified radical mastectomy and individualswith dense breast parenchyma were excluded. We evaluated radiography of resected specimens to assess marginspiculation, distance of mass/microcalcification from the excised margin, presence of a mass, and presence of anyadjacent microcalcification, Other features including mass size, nuclear grade and patient's age were also recorded andall were analyzed for any association with CLE. Results: Absence of adjacent microcalcification and the presence of amass on radiographs showed significant associations with CLE, but no links were evident with other features. Specimenradiography was found to be a sufficient tool to predict CLE with a positive predictive value of 83.3%, a sensitivity of80.7% and a specificity of 81%. Conclusion: Specimen radiography is an important and sensitive tool to predict CLE. PMID- 29582634 TI - Characterization of Apoptosis in a Breast Cancer Cell Line after IL-10 Silencing AB - Background: Breast cancer is affected by the immune system in that different cytokines play roles in its initiationand progression. Interleukin-10 (IL-10), an anti-inflammatory cytokine, is an immunosuppressive factor involved intumorigenesis. The present study was conducted to investigate the gene silencing effect of a small interference RNA(siRNA) targeting IL-10 on the apoptotic pathway in breast cancer cell line. Methods: The siRNA targeting IL-10 anda glyceraldehyde 3-phosphate dehydrogenase (GAPDH) clone were introduced into MDA-MB-231 cells. Real-timePCR assays were used to determine IL-10 and GAPDH gene expression levels, in addition to those for protein kinaseB (AKT), phosphoinositide 3-kinase (PI3K), B-cell lymphoma 2 (Bcl2), caspase-3 and caspase 9 genes related toapoptosis. Results: Inhibition of IL-10 by the siRNA accelerated apoptosis and was accompanied by significantincrease in caspase-3 and caspase-9 and a significant decrease in PI3K, AKT and Bcl2 expression levels compared tothe non-transfected case. Conclusions: In conclusion, the production of IL-10 may represent a new escape mechanismby breast cancer cells to evade destruction by the immune system. IL-10 gene silencing causes down regulation of bothPI3K/AKT and Bcl2 gene expression and also increases the Bbc3, BAX caspase3, and caspase 3 cleavage expressionlevels. IL-10 might represent a promising new target for therapeutic strategies. PMID- 29582635 TI - Possible Synergistic Interactions Among Multiple HPV Genotypes in Women Suffering from Genital Neoplasia AB - Objective: Persistence of HPV infection is the true cause of cervical disorders. It is reported that competitionmay exist among HPV genotypes for colonization. This survey was designed to establish the multiple HPV genotypestatus in our community and the probability of multiple HPV infections involvement. Methods: All multiple HPVinfections were selected for investigation in women suffering from genital infections referred to private laboratoriesin Tehran, Iran. A total of 160 multi HPV positive specimens from cervical scraping were identified by the HPVgenotyping methods, "INNO-LiPA and Geno Array". Result: In present study, HPV 6 (LR), 16 (HR), 53 (pHR), 31(HR) and 11 (LR) were included in 48.8% of detected infections as the most five dominant genotypes. HPV 16 wasdetected at the highest rate with genotypes 53, 31 and 52, while HPV 53 appeared linked with HPV 16, 51 and 56in concurrent infections. It appears that HPV 16 and 53 may have significant tendencies to associate with each otherrather than with other genotypes. Analysis of the data revealed there may be some synergistic interactions with a fewparticular genotypes such as "HPV 53". Conclusion: Multiple HPV genotypes appear more likely to be linked withdevelopment of cervical abnormalities especially in patients with genital infections. Since, there are various patternsof dominant HPV genotypes in different regions of world, more investigations of this type should be performed forcareHPV programs in individual countries. PMID- 29582636 TI - Individual and Integrated Effects of Potential Risk Factors for Oral Squamous Cell Carcinoma: A Hospital-Based Case-Control Study in Jazan, Saudi Arabia AB - Background: Oral cancer is the sixth most common cancer in the world, with a high prevalence reported in Jazanprovince of Saudi Arabia. The objectives of this study were to check individual and integrated effects of potential riskfactors for oral squamous cell carcinoma. Materials and methods: A case control study was designed with a sampleof 210 subjects, in which histopathologically confirmed incident cases (n=70) and controls (n=140) matched for age,gender and referral route, were recruited. Differences in exposure to potential risk factors between cases and controlswere assessed using chi-square and McNemar analyses. A logistic regression model with interactions was applied to checkindividual and integrated effects. Results: Mean age of the sample was 55 years (+ 20 years). Shammah (O.R = 33.01;C.I = 3.22 - 39.88), shisha (O.R = 3.96; C.I = 0.24 - 63.38), and cigarette (O.R = 1.58; C.I = 0.13, 2.50) consumptionwas significantly associated (P<0.05) with oral squamous cell carcinoma development. In contrast, Khat chewing (O.R= 0.67; C.I = 0.19-2.36) was without significant effect. An increase in odds ratios was observed when combinationsof shammah and shisha (O.R = 35.03; C.I = 11.50-65.66), shisha and cigarettes (O.R = 10.52; C.I = 1.03 - 33.90) orshamma and cigarettes (O.R = 10.10; C.I = 0.50 - 20.40) were used. Conclusion: Combined exposure to risk-factorshas serious implications and policies on oral cancer prevention should be designed with attention to this aspect. PMID- 29582637 TI - Swallowing Exercises: Will They Really Help Head and Neck Cancer Patients? AB - Purpose: The work was a comparative study, the aim of which is to evaluate the impact of swallowing exercises onswallowing problems among head and neck cancer patients (HNCPs) after CRT. Methods: The sample of 60 HNCPswas equally divided into control and study groups. The investigators met all patients 3 times (before, during and afterCRT); swallowing ability was assessed using the Sydney Swallowing Questionnaire (SSQ). The University of Texas,MD Anderson Cancer Center Swallowing Exercise Protocol was explained and demonstrated by the investigators tothe study group. All tools used were translated into Arabic. Data analyses were carried out using the statistical packagefor social sciences (SPSS), program version 20. Results: Most of the patients from both groups experienced milddysphagia during the 1st visit. By the 3rd visit, severe dysphagia (to thin and thick liquids, and soft and hard food)was higher in the control group (73.3%) compared to the study group (26.7%). By the third visit there was statisticallysignificant difference between both groups in swallowing thin liquids (p = 0.01), as well as thick liquids (p = 0.01).At the 1st visit, there was no significant difference regarding swallowing soft food (p = 0.24), hard food (p = 0.17),dry food (p = 0.89) and swallowing Saliva (p = 0.28). While by the 3rd visit, there was significant difference betweencontrol and study groups in all parameters. Conclusions: Adequate prevention and treatment of dysphagia, with useof swallowing programs, is essential to plan a complete therapeutic programme. PMID- 29582638 TI - Extraction and Characterization of Chick PEA (Cicer arietinum) Extract with Immunostimulant Activity in BALB/C MICE AB - Traditional plant medicines are used for a range of cancer conditions. The chickpea is highly proteinaceous andconsumed as a staple in many parts of the world. An evaluation of chemoprotective and immunomodulatory activitiesof Cicer arietinum (CE) in cisplatin-induced immunosuppressed mice was here performed. Cisplatin was givenat 100mg/kg, intraperitoneally, and after induction of immunosuppression mice were treated with Cicer arietinum(0.5 mg/dose/animal/IP) for a period of 10-day. The influence of the extract on lymphoid organ weight, bone marrowcellularity, alpha esterase activity and on enzyme levels such as (SGOT,SGPT, Urea, Creatinine was assessed toidentify any chemoprotective influence. Administration of CE to cisplatin-treated mice alleviated the drastic reductionin bone marrow cellularity and alpha- esterase positive cells seen with cisplatin. Thus myelosuppression was reversed orinhibited. Cisplatin bids to DNA and causes damage resulting in chromosome breaks, micronucleus formation and celldeath. CE is comprised of numerous middle-chain aliphatic alcohols, aldehydes and ketones, in addition to compoundslike 7-hydroxy-1-methoxy-6 methylanthraquinone, cyclohexadecane (CAS) and 6-(amino methyl)-2-naphthol. Theselatter are thought to contribute to the characteristic aroma of C. arietimnum. In conclusion, administration of CEin cisplatin-treated mice, boosted bone marrow cellularity and increased alpha- esterase positive cells, thus reversingmyelosupproession. PMID- 29582640 TI - Effectiveness of a Mass Media Campaign on Oral Carcinogens and Their Effects on the Oral Cavity AB - Objective: To develop a mass media campaign on oral carcinogens and their effects on the oral cavity in orderto increase awareness among the general population. Methods: Documentary and public service announcementshighlighting the effects of tobacco and its products were designed and developed based on principles of behavior change. Aquestionnaire, designed to determine the knowledge, attitude and practice of people regarding oral carcinogens, was usedto conduct a baseline survey at various sites in eastern Nepal. Local television channels and radio stations broadcastedthe documentary and public service announcements. An evaluation survey was then performed to assess the effectivenessof the campaign. Results: Baseline and evaluation surveys covered 1,972 and 2,140 individuals, respectively. A thirdof the baseline population consumed quid, 22% chewing tobacco, 16% gutka (commercial preparation of arecanut,tobacco, lime and chemicals) and 25% cigarettes. Tobacco consumption differed significantly between 3 ecologic regionswith greater use in the Terai region. The knowledge prevalence regarding the oral carcinogens quid (70%), chewingtobacco (82%), gutka (58%) and cigarettes (93%) significantly increased in the evaluation population. Females weremore aware about the various tobacco products and their effects on health. More people knew about the harmful effectsof tobacco on their health and oral cavity, and had their mouth examined and the frequency of consumption of theseproducts reduced significantly after the campaign. Attitudes towards production, sale and advertisements of tobaccoalso improved significantly. Conclusions: The mass media campaign was an effective tool for increasing awarenessamong the population. PMID- 29582639 TI - Diagnostic Value of Glypican-3 for Hepatocellular Carcinomas AB - Background: Hepatocellular carcinoma (HCC) is a common and dangerous malignancy in many parts of the world,and especially in Egypt. Early diagnosis is the most important step in successful HCC management. However mostcases are detected at late stage making effective intervention impossible. Aim: The aim of this study was to evaluatethe potential of Glypican-3 (GPC-3) to aid in diagnosis of HCC, especially in patients with low serum alpha-fetoprotein(AFP). Subjects and methods: Serum GPC-3 was assessed by flow-cytometry and serum AFP by enzyme linkedimmunosorbent assay (ELISA) in 40 HCC patients with AFP< 400ug?l. (GI), 40 HCC patients with AFP> 400ug?l.(GII) and 20 healthy controls (GIII). Results: GPC 3 was found to be significantly elevated in HCC as compared tohealthy subjects (GI 38.2+/-22. 5, GII 50.2+/-22.6, and GIII 2.24+/-1.19), with sensitivities of 85% for GI and 84% for GIIand specificities of 95% for GI and 92% for GII. AFP showed respective sensitivities of 50% and 79%, and specificitiesof 80% and 90%, for HCC diagnosis. The combination of GPC-3 with AFP achieved the highest sensitivity (98.5%) andspecificity (97.8%). Conclusion: Serum GPC-3 has a better sensitivity than AFP for the diagnosis of HCC. Combinationof two markers appears warranted for greatest accuracy. PMID- 29582641 TI - Factors Affecting Uptake of Cervical Cancer Screening Among African Women in Klang Valley, Malaysia AB - Introduction: Cervical cancer is a health concern among women worldwide, presently ranking as the second to fourthcommon cancer type among women in different parts of the world. Human papillomaviruses (HPV) 16 and 18 are themain causative agents of cervical cancer. However, prevention is possible with early and regular cervical cancer screening.Objective: This study aimed to identify the cervical cancer screening practices and factors affecting the screeningstatus of African immigrant women attending selected church services in Klang Valley, Malaysia. Methodology:A cross-sectional study among 320 randomly selected respondents between ages 18-69 was conducted in three differentchurches with high numbers of African participants. A self-administered questionnaire was distributed among therespondents. To ensure a good understanding, the questionnaire was written and self-explained in English language,because English is the general spoken language among the study population. Three levels of analysis were conductedusing SPSS 21, involving descriptive analysis, chi square and multiple logistic regression. Results: The response ratewas 98.2%, the majority (68.1%) of the respondents being aged 31-50 years and married. The prevalence of screeningamong the respondents over the past 3 years was 27.2%. Using a p-value of 0.05 as the significance level, the finalmodel showed that marital status (p=0.004), knowledge (p=0.035), perceived barriers (p=0.003), and having a regularhealth care provider (p<0.001) were the only significant predicting factors of uptake of cervical screening among Africanimmigrant women in Klang Valley, Malaysia. Conclusion: The findings revealed that the uptake of cervical cancerscreening among the African women was very low. Marital status, knowledge, perceived barriers and having a regularhealth care provider were the predictive factors. Specific awareness programs to increase uptake should be designed andimplemented by the relevant authorities. PMID- 29582642 TI - Leukotriene Receptor Antagonists Inhibit Mitogenic Activity in Triple Negative Breast Cancer Cells AB - Despite a discovery of hormonal pathways regulating breast cancer, a definitive cure for the disease requires furtheridentification of alternative targets that provide a hormone-independent support. Apart from their role in inflammatorydiseases, cysteinyl leukotriene (CysLT) receptor antagonists (LTRAs) decrease the risk of lung cancer in asthma patientsand inhibit tumor progression in several malignancies. In the present study, we evaluate the effects of two chemicallydifferent, clinically relevant LTRAs (montelukast and zafirlukast) in a triple negative breast cancer cell line, MDAMB-231. We found that these two LTRAs reduced breast cancer cell viability in a dose-dependent manner with the50% inhibitory concentration (IC50) between 5-10 MUM. Although both LTRAs have several pharmacological propertiesin common, we noticed that montelukast mainly induced apoptosis, while zafirlukast mainly exerted its action on cellcycle. However, the precise mechanisms responsible for such different effects remain unclear. In summary, our resultssuggest that CysLT plays a role in proliferation and survivability of breast cancer cells in the absence of hormonal stimuli. PMID- 29582643 TI - Chemopreventive Effects of Edible Canna (Canna edulis Kerr.) Against Colorectal Carcinogenesis: Effects on Expression of Adenomatous Polyposis Coli and Inducible Nitric Oxide Synthase in Rat Inflammatory Model AB - Objective: Dietary high fibre and calcium intake has been suggested to reduce colorectal cancer risk. However, thereis limited information available regarding the potential of edible canna (Ganyong), with high dietary fibre and calciumcontent, to act as a preventive agent for colorectal cancer. This experimental study was conducted to investigate thepreventive effect of Ganyong in reducing colorectal carcinogenesis with attention to effects on adenomatous polyposiscoli (APC) and inducible nitric oxide synthase (iNOS) expression. Methods: Thirty male Wistar rats were dividedinto 5 equal groups; a normal control group without azoxymethane/dextran sodium sulphate (AOM/DSS) inductionand Ganyong, a 'cancer' control group with AOM/DSS induction only, and three treatment groups with AOM/DSSinduction and different percentages (5%, 10% and 20%) of Ganyong. Paraffin-embedded sections of rat colon tissuewere analysed by haematoxylin-eosin and immunohistochemical staining against antibodies against APC and iNOS.Variation in rates of APC and iNOS expression were analyzed using the Kruskal-Wallis test followed by the Dunn'stest (SPSS statistic version 24). P<0.05 was considered statistically significant. Results: AOM/DSS induction increasedthe expression of APC (p=0.013) and iNOS (p=0.013) compared to the normal control group. APC expression in thetreated groups was lower than in the 'cancer' control group (p=0.049), especially in the 10% Ganyong group (p=0.02).In contrast, there was no significant variation among the treated groups regarding iNOS expression. Histopathologicalfeatures of the colon supported the data for APC and iNOS expression. Conclusion: This study indicated potentialchemopreventive effects of Ganyong reducing expression of factors contributing to colorectal carcinogenesis. PMID- 29582645 TI - Quality of Breast Cancer Surgical Pathology Reports AB - Background: Surgical pathology reporting of breast cancer is needed for appropriate staging and treatment decisions.We here checked the quality of surgical pathology reports of breast cancer from different laboratories of Karachi,Pakistan. Methods: One hundred surgical pathology reports from ten different laboratories of Karachi were assessedfor documentation of elements against a checklist adopted from the CAP guideline over a period of six months fromJanuary, 2017 to June, 2017 in the Oncology Department, Jinnah Postgraduate Medical Centre, Karachi. Results: Outof 100 reports, clinical information was documented in 68%, type of procedure and lymph node sampling in 84%and 34% respectively.

PMID- 29582644 TI - Nasopharyngeal Carcinoma Protein Interaction Mapping Analysis via Proteomic Approaches AB - Nasopharyngeal carcinoma (NPC), although not very common in many parts of the world, is a major concern insome countries, including Iran. Molecular studies are very helpful to provide essential information regarding underlyingcarcinogenetic mechanisms. Here, considering NPC proteomic approaches, established biomarkers were designated forprotein-protein interaction network construction and analysis with corresponding plug-ins. A network of reported proteinmarkers was constructed and topological and biological process features were investigated. Centrality analysis showedthat JUN, CALM1, HSB1, and SOD1 are more important than other differentially expressed proteins in an interactingpattern. What is more, by extending the network, Tp53, PRDM10, AKT1, ALB, HSP90AA1, and EGFR achieved thehighest values for NPC network strength. It can be concluded that these proteins as well as their contributing processes,particularly in a second network, may be important for NPC onset and development. Targeting these candidate proteinsmay allow novel treatment approaches following appropriate validation. PMID- 29582646 TI - A Germline Mutation in the BRCA1 3'UTR Variant Predicts Susceptibility to Breast Cancer in a Saudi Arabian Population AB - Purpose: The impact of the BRCA1-3'UTR-variant on BRCA1 gene expression and altered responses to externalstimuli was previously tested in vitro using a luciferase reporter assay. Its ability to predict breast cancer risk in womenwas also assessed but the conclusions were inconsistent. The present study concerns the relationship between theBRCA1-3'UTR germline variant rs8176318G>T and susceptibility to Breast cancer in an ethnic population of SaudiArabia. Methodology: The study included 100 breast cancer patients and 100 sex matched healthy controls fromthe northwestern region (Tabuk) and Dammam of Saudi Arabia were investigated for the BRCA1-3'UTR germlinevariant rs8176318G>T using an allele specific PCR technique. Genotype distributions were then compared. Results:The frequencies of the three genotypes GG, TT and GT in our Saudi Arabian patients were 26%, 8% and 66% andin healthy controls were 45%, 5% and 50%, respectively (p=0.03). Risk of developing breast cancer was found to besignificantly associated with the GT variant (OR 2.28, 1.24-4.191; RR 1.47, 1.11-1.93; P=0.007), GT+TT (OR, 2.32,1.28-4.22; RR 1.48, 1.13-1.94; P=0.005) and the T allele (OR 1.62 , 1.072- 2.45; RR 1.28, 1.02-1.60: P=0.020). Therewere 2.76 and 2.28 fold increase risks of developing breast cancer associated with the TT and GT genotypes in ourcases. A significant correlation was also found between the BRCA1 3'UTR variants with the stage of the disease anddistant metastasis but not with age, grade, and ER, PR and her2/neu status. Conclusion : The rs8176318G/T in the3'untranslated region (UTR) of the BRCA1 gene was found to be associatedwith increased susceptibility to breastcancer in our study population, increased risk being noted with the GT and TT genotypes. Further association studiesare needed to confirm this finding in other regions of Saudi Arabia.

AB - Efficient sensing of sulfur containing toxic gases like H2S and SO2 is of the utmost importance due to the adverse effects of these noxious gases. Absence of an efficient 2D-based nanosensor capable of anchoring H2S and SO2 with feasible binding and an apparent variation in electronic properties upon the exposure of gas molecules has motivated us to explore the promise of a germanene nanosheet (Ge-NS) for this purpose. In the present study, we have performed a comprehensive computational investigation by means of DFT-based first-principles calculations to envisage the structural, electronic, and gas sensing properties of pristine, defected, and metal substituted Ge-NSs. Our initial screening has revealed that although interaction of SO2 with pristine Ge-NSs is within the desirable range, H2S binding however falls below the required values to guarantee an effective sensing. To improve the binding characteristics, we have considered the interactions between H2S and SO2 with defected and metal substituted Ge-NS. The systematic removals of Ge atoms from a reasonably large super cell lead to monovacancy, divacancies, and trivacancies in Ge-NS. Similarly, different transition metals like As, Co, Cu, Fe, Ga, Ge, Ni, and Zn have been substituted into the monolayer to realize substituted Ge-NS. Our van der Waals corrected DFT calculations have concluded that the vacancy and substitution defects not only improve the binding characteristics but also enhance the sensing propensity of both H2S and SO2. The total and projected density of states show significant variations in electronic properties of pristine and defected Ge-NSs before and after the exposure to the gases, which are essential in constituting a signal to be detected by the external circuit of the sensor. We strongly believe that our present work would not only advance the knowledge towards the application of Ge NS-based sensing but also provide motivation for the synthesis of such efficient nanosensor for H2S and SO2 based on Ge monolayer.

In tumorigenesis, c-Fospromotes invasive growth through down-regulation of tumor suppressor genes but its role in oral carcinogenesis is notclear. Objectives: This study concerned c-fos gene expression in normal and malignant tissues of the oral cavity, withattention to associations between expression status and clinico-pathological profiles of OSCC patients. Method: A totalof 65 histopathologically confirmed OSCC tissue samples were included in case group along with an equal number ofage and sex-matched normal tissue samples of oral cavity for the control group. c-Fos protein and m RNA expressionswere analyzed using immunohistochemistry and qRT-PCR, respectively. Results: A significant low expression of c-Fosprotein was observed in OSCC cases than normal control subjects (p= <0.001). The mean percent positivity of c-Fosprotein in cases vs. controls was 24.91+/- 2.7 vs. 49.68+/- 2.2 (p= <0.001). Most OSCC tissue samples showed weak ormoderate c-Fos expression whereas 53.8% of normal tissue sections presented with strong immunostaining. Moreover,the relative m-RNA expression for the c-fos gene was significantly decreased in case group (0.93+/- 0.48) as compared tothe control group (1.22+/- 0.87). Majority of c-Fos positive cases were diagnosed with well developed tumor. The meanpercent positivity of c-Fos protein was significantly lower in higher grade tumor as compared with normal oral mucosa(p= < 0.001). Conclusion: The present study suggested that the c-fos gene is downregulated in oral carcinomas. Thedisparity of c-Fos protein levels in different pathological grades of tumor and normal oral tissue samples may indicatethat loss of c-Fos expression is related with the progression of OSCC. PMID- 29582649 TI - Highly Stretchable, Weavable, and Washable Piezoresistive Microfiber Sensors. AB - A key challenge in electronic textiles is to develop an intrinsically conductive thread of sufficient robustness and sensitivity. Here, we demonstrate an elastomeric functionalized microfiber sensor suitable for smart textile and wearable electronics. Unlike conventional conductive threads, our microfiber is highly flexible and stretchable up to 120% strain and possesses excellent piezoresistive characteristics. The microfiber is functionalized by enclosing a conductive liquid metallic alloy within the elastomeric microtube. This embodiment allows shape reconfigurability and robustness, while maintaining an excellent electrical conductivity of 3.27 +/- 0.08 MS/m. By producing microfibers the size of cotton threads (160 MUm in diameter), a plurality of stretchable tubular elastic piezoresistive microfibers may be woven seamlessly into a fabric to determine the force location and directionality. As a proof of concept, the conductive microfibers woven into a fabric glove were used to obtain physiological measurements from the wrist, elbow pit, and less accessible body parts, such as the neck and foot instep. Importantly, the elastomeric layer protects the sensing element from degradation. Experiments showed that our microfibers suffered minimal electrical drift even after repeated stretching and machine washing. These advantages highlight the unique propositions of our wearable electronics for flexible display, electronic textile, soft robotics, and consumer healthcare applications.

AB - A GtfB enzyme 4,6-alpha-glucanotransferase from Streptococcus thermophilus lacking 761 N-terminal amino acids was heterologously expressed in Escherichia coli. Purified S. thermophilus GtfB showed transglycosylation activities toward starch, resulting in branch points of (alpha1->6)-glycosidic linkages plus linear chains of (alpha1->4)-glycosidic linkages. After wheat starch was modified at a rate of 0.1 g/mL by 1-4 U/g starch GtfB at pH 6.0 and 40 degrees C for 1 h, the weight-averaged molecular weight decreased from 1.70 * 107 g/mol to 1.21 * 106 to 3.41 * 106 g/mol, the amylose content decreased from 22.07 to 16.34-17.11%, and that of amylopectin long-branch chains decreased from 26.4 to 10.25-15.64% ( P < 0.05). After the GtfB-modified wheat starches were gelatinized and stored at 4 degrees C for 1-2 weeks, their endothermic enthalpies were significantly lower than that of the control sample ( P < 0.05), indicating low retrogradation rates. PMID- 29582652 TI - In Vivo Quantitative Monitoring of Subunit Stoichiometry for Metabolic Complexes. AB - Metabolic pathways often employ assemblies of individual enzymes to facilitate substrate channeling to improve thermodynamic efficiency and confer pathway directionality. It is often assumed that subunits to multienzyme complexes are coregulated and accumulate at fixed levels in vivo, reflecting complex stoichiometry. Such assumptions can be experimentally tested using modern tandem mass spectrometry, and herein we describe such an approach applied toward an important metabolic complex. The committed step of de novo fatty acid synthesis in the plastids of most plants is catalyzed by the multienzyme, heteromeric acetyl-CoA carboxylase (hetACCase). This complex is composed of four catalytic subunits and a recently discovered regulatory subunit resembling the biotin carboxyl carrier protein but lacking the biotinylation motif necessary for activity. To better understand this novel form of regulation, a targeted tandem mass-spectrometry-based assay was developed to absolutely quantify all subunits to the Arabidopsis thaliana hetACCase. After validation against pure, recombinant protein, this multiplexed assay was used to quantify hetACCase subunits in siliques in various stages of development. Quantitation provided a developmental profile of hetACCase and BADC protein expression that supports a recently proposed regulatory mechanism for hetACCase and demonstrates a promising application of targeted mass spectrometry for in vivo analysis of protein complexes.

AB - A hypervalent iodine(III) reagent mediated oxidative skeletal rearrangement reaction of secondary amines is reported. The transformation, which uses PhI(OAc)2 in CF3CH2OH, was found to be highly efficient at inducing the direct 1,2-C-to-N migration of secondary amines. This method offers facile and divergent access to polycyclic and macrocyclic indole-fused compounds. The synthetic potential of the method is also demonstrated through its application to several substrates, including secondary as well as primary amines. PMID- 29582655 TI - In Situ Pt Staining Method for Simple, Stable, and Sensitive Pressure-Based Bioassays. AB - Pressure-based bioassays (PASS) integrate a molecular recognition process with a catalyzed gas generation reaction, enabling sensitive and portable quantitation of biomarkers in clinical samples. Using platinum nanoparticles (PtNPs) as a catalyst has significantly improved the sensitivity of PASS compared with protein enzyme-based detection. However, PtNPs are easily deactivated during storage or after being decorated with antibodies. Moreover, nonspecific adsorption of PtNPs on substrates has been a problem, resulting in significant backgrounds. To solve these problems of PtNP-based detection, we report a robust, simple, stable, and sensitive Pt staining method for PASS. Detection antibody-decorated gold nanoparticles (AuNPs) are used to perform enzyme-linked immunosorbent assay, followed by Pt staining to stain AuNPs with Ag and Pt bimetallic shells (Au@AgPtNPs), which endow AuNPs with catalytic activity. The concentration of targets can be quantitatively determined by measuring the pressure due to O2 gas (g) formed by the decomposition of H2O2 catalyzed by Au@AgPtNPs. C-reactive protein and avian influenza hemagglutinin 5 neuraminidase 1 can be quantitatively detected with detection limits of 0.015 and 0.065 ng/mL, respectively. The simple, stable, and sensitive properties of the Pt staining-based method will largely broaden the applications of PASS in clinical diagnosis and biomedicine. PMID- 29582654 TI - Optically Triggered Planarization of Boryl-Substituted Phenoxazine: Another Horizon of TADF Molecules and High-Performance OLEDs. AB - We report the unprecedented dual properties of excited-state structural planarization and thermally activated delayed fluorescence (TADF) of 10 dimesitylboryl phenoxazine, i.e., PXZBM. Bearing a nonplanar phenoxazine moiety, PXZBM shows the lowest lying absorption onset at ~390 nm in nonpolar solvents such as cyclohexane but reveals an anomalously large Stokes-shifted (~14 500 cm 1) emission maximized at 595 nm. In sharp contrast, when a phenylene spacer is added between phenoxazine and dimesitylboryl moieties of PXZBM, the 10-(4 dimesitylborylphenyl)phenoxazine PXZPBM in cyclohexane reveals a much blue shifted emission at 470 nm despite its red-shifted absorption maximized at 420 nm (cf. PXZBM). The emission of PXZBM further reveals solvent polarity dependence, being red-shifted from 595 nm in cyclohexane to 645 nm in CH2Cl2. For rationalization, the steric hindrance between phenoxazine and the dimesitylboryl unit in PXZBM caused a puckered arrangement of phenoxazine at the ground state. Upon electronic excitation, as supported by the femtosecond early relaxation dynamics, spectral-temporal evolution and energetics calculated along the reaction potential energy surfaces, the diminution of N -> B electron transfer reduces pi-conjugation and elongates the N-B bond length, inducing the fast phenoxazine planarization with a time constant of 890 +/- 100 fs. The associated charge-transfer reaction from phenoxazine (donor) to dimesitylboryl unit (acceptor) results in a further red-shifted emission in polar solvents. In stark contrast, PXZPBM shows a planar phenoxazine and undergoes excited-state charge transfer only. Despite the distinct difference in excited-state relaxation dynamics, both PXZBM and PXZPBM exhibit efficient TADF capable of producing highly efficient orange and green organic light emitting diodes with peak efficiencies of 10.9% (30.3 cd A-1 and 18.7 lm W-1) and 22.6% (67.7 cd A-1 and 50.0 lm W-1). PMID- 29582656 TI - Modeling the Transport of the "New-Horizon" Reduced Graphene Oxide-Metal Oxide Nanohybrids in Water-Saturated Porous Media. AB - Little is known about the fate and transport of the "new-horizon" multifunctional nanohybrids in the environment. Saturated sand-packed column experiments ( n = 66) were therefore performed to investigate the transport and retention of reduced graphene oxide (RGO)-metal oxide (Fe3O4, TiO2, and ZnO) nanohybrids under environmentally relevant conditions (mono- and divalent electrolytes and natural organic matter). Classical colloid science principles (Derjaguin-Landau-Verwey Overbeek (DLVO) theory and colloid filtration theory (CFT)) and mathematical models based on the one-dimensional convection-dispersion equation were employed to describe and predict the mobility of RGO-Fe3O4, RGO-TiO2, and RGO-ZnO nanohybrids in porous media. Results indicate that the mobility of the three nanohybrids under varying experimental conditions is overall explainable by DLVO theory and CFT. Numerical simulations suggest that the one-site kinetic retention model (OSKRM) considering both time- and depth-dependent retention accurately approximated the breakthrough curves (BTCs) and retention profiles (RPs) of the nanohybrids concurrently; whereas, others (e.g., two-site retention model) failed to capture the BTCs and/or RPs. This is primarily because blocking BTCs and exponential/hyperexponential/uniform RPs occurred, which is within the framework of OSKRM featuring time- (for kinetic Langmuirian blocking) and depth-dependent (for exponential/hyperexponential/uniform) retention kinetics. Employing fitted parameters (maximum solid-phase retention capacity: Smax = 0.0406-3.06 cm3/g; and first-order attachment rate coefficient: ka = 0.133-20.6 min-1) extracted from the OSKRM and environmentally representative physical variables (flow velocity (0.00441-4.41 cm/min), porosity (0.24-0.54), and grain size (210-810 MUm)) as initial input conditions, the long-distance transport scenarios (in 500 cm long sand columns) of the three nanohybrids were predicted via forward simulation. Our findings address the existing knowledge gap regarding the impact of physicochemical factors on the transport of the next-generation, multifunctional RGO-metal oxide nanohybrids in the subsurface. PMID- 29582657 TI - Stabilization of Lipase in Polymerized High Internal Phase Emulsions. AB - Candida antarctica lipase B is stabilized in a porous, high internal phase emulsion (HIPE) of polydicyclopentadiene to enable biocatalytic waste stream upcycling. The immobilized lipase is subjected to thorough washing conditions and tested for stability in extreme environments and reusability. A porous internal microstructure is revealed through scanning electron microscopy. After preparation, lipase activity increased to 139 +/- 9.7% of its original activity. After 10 cycles of reuse, immobilized lipase retains over 50% activity. Immobilized lipase retains activity after 24 h of exposure to temperatures ranging from 20 to 60 degrees C and pH values of 3, 7, and 10. In the most extreme environments tested, lipase retained 42.8 +/- 21% relative activity after exposure to 60 degrees C and 49.4 +/- 16% relative activity after exposure to pH 3. Polymerized HIPEs stabilize lipase and, thus, extend its working range. Further synthesis optimization has the potential to increase enzyme stability, immobilization efficiency, and uniformity. The reported hierarchical stabilization technique shows promise for use of immobilized lipase in non-ideal, industrially relevant conditions. PMID- 29582658 TI - Surface Behavior of BSA/Water/Carbohydrate Systems from Molecular Polarizability Measurements. AB - The effect of the presence of glucose and sucrose on the nonintrinsic contribution to partial molar volume ?Theta?ni of bovine serum albumin (BSA) is determined by means of static and dynamic electronic polarizability measurements. For that aim, a combined strategy based on high-resolution refractometry, high exactitude densitometry, and synchronous fluorescence spectroscopy is applied. Both static and dynamic mean electronic molecular polarizability values are found to be sensitive to the presence of glucose. In the case of sucrose, the polarizability of BSA is not appreciably affected. In fact, our results revealed that the electronic changes observed occurred without a modification of the native conformation of BSA. On the contrary, a nonmonotonous behavior with the concentration is observed in presence of glucose. These results advocate the influence of the electronic polarization on the repulsive and attractive protein carbohydrate interactions. An analysis using the scaled particle theory indicates that the accumulation of glucose on the protein surface promotes dehydration. Inversely, hydration and preferential exclusion occur in the vicinity of the protein surface for sucrose-enriched systems. PMID- 29582659 TI - Cigarillo and Little Cigar Mainstream Smoke Constituents from Replicated Human Smoking. AB - Little cigar and cigarillo smoking is increasing in popularity in the U.S., but little is known about the topography and mainstream smoke (MSS) constituents of these types of cigar products. This report describes the quantity of selected MSS toxicants generated from puff-by-puff replication of human laboratory smoking. Participants were dual users of cigarettes and either little cigars ( n = 21) or cigarillos ( n = 23). In the laboratory smoking session, participants of the little cigar group smoked a filtered unflavored Winchester Little Cigar; those in the cigarillo group smoked an unfiltered, unflavored Black & Mild cigarillo. MSS components included both volatiles and semivolatile compounds. The MSS of five representative U.S. domestic cigarettes was generated using smoking topography profiles of the participants smoking their own brand of cigarettes. Machine smoking accurately replicated individual puff profiles as indicated by a high correlation between lab and machine smoked: time to smoke, number of puffs, and total puff volume. There was wide variability in smoking patterns across subjects of both little cigars and cigarillos. For example, total puff volume ranged from 84 to 732 mL after the little cigar and from 270 to 2089 mL after the cigarillo. Qualitatively, cigar smoke from little cigars and cigarillos were similar and resembles cigarette smoke. All analytes (VOC and SVOCs) were greater in cigarillo smoke compared to that of little cigars and cigarettes. However, when the toxicants were adjusted for grams of tobacco burned, little cigar smoke contained more nicotine, tobacco-specific nitrosamines, acetonitrile, and acrylonitrile compared with cigarillo smoke. When the constituents were adjusted for nicotine content, cigarillo MSS contained more of all toxicants compared with little cigar. Cigarillos and little cigars, like cigarettes, deliver nicotine and other toxicants known to be harmful to health; their regulation by the FDA is appropriate for their public health risk. PMID- 29582660 TI - Occurrence of Single- and Double-Peaked Emission Profiles of Synthetic Chemicals. AB - This work aims to elucidate the circumstances that can lead to two peaks in the temporal emission profile of synthetic chemicals. Using a simplified substance flow model, we explore how emission factors, product lifespan, and degradation half-life in waste stock influence the (i) relative importance of emissions from three lifecycle stages (industrial processes, use phase, and waste disposal), and (ii) the resulting composite emission profile. A double-peaked emission profile occurs if the lifespan of products containing the chemical is longer than its production history, and the gross emission factor from waste disposal exceeds that from the use phase. Since most chemicals fail to meet these two conditions, it is reasonable to use single-peaked emission profile as the default in environmental studies. On the basis of their emission profiles and contributions from individual lifecycle stages, we can categorize chemicals into "simple single peakers", "composite single-peakers", and "double-peakers". Our simplified model derived emission profiles for five real chemicals that agree well with earlier, more sophisticated calculations, indicating the model's ability to capture the essential features of actual emissions. It is hoped that the model and conclusions in this work will benefit both environmental modelers and decision makers.

AB - Topological insulators are a class of band insulators with nontrivial topology, a result of band inversion due to the strong spin-orbit coupling. The transition between topological and normal insulator can be realized by tuning the spin-orbit coupling strength and has been observed experimentally. However, the impact of chemical disorders on the topological phase transition was not addressed in previous studies. Herein, we report a systematic scanning tunneling microscopy/spectroscopy and first-principles study of the topological phase transition in single crystals of In-doped Bi2Se3. Surprisingly, no band gap closure was observed across the transition. Furthermore, our spectroscopic imaging results reveal that In defects are extremely effective "suppressors" of the band inversion, which leads to microscopic phase separation of topological insulator-like and normal-insulator-like nano regions across the "transition". The observed topological electronic inhomogeneity demonstrates the significant impact of chemical disorders in topological materials, shedding new light on the fundamental understanding of topological phase transition. PMID- 29582664 TI - Microhydration of Dibenzo-18-Crown-6 Complexes with K+, Rb+, and Cs+ Investigated by Cold UV and IR Spectroscopy in the Gas Phase. AB - In this Article, we examine the hydration structure of dibenzo-18-crown-6 (DB18C6) complexes with K+, Rb+, and Cs+ ion in the gas phase. We measure well resolved UV photodissociation (UVPD) spectra of K+.DB18C6.(H2O) n, Rb+.DB18C6.(H2O) n, and Cs+.DB18C6.(H2O) n ( n = 1-8) complexes in a cold, 22 pole ion trap. We also measure IR-UV double-resonance spectra of the Rb+.DB18C6.(H2O)1-5 and the Cs+.DB18C6.(H2O)3 complexes. The structure of the hydrated complexes is determined or tentatively proposed on the basis of the UV and IR spectra with the aid of quantum chemical calculations. Bare complexes (K+.DB18C6, Rb+.DB18C6, and Cs+.DB18C6) have a similar boat-type conformation, but the distance between the metal ions and the DB18C6 cavity increases with increasing ion size from K+ to Cs+. Although the structural difference of the bare complexes is small, it highly affects the manner in which each is hydrated. For the hydrated K+.DB18C6 complexes, water molecules bind on both sides (top and bottom) of the boat-type K+.DB18C6 conformer, while hydration occurs only on top of the Rb+.DB18C6 and Cs+.DB18C6 complexes. On the basis of our analysis of the hydration manner of the gas-phase complexes, we propose that, for Rb+.DB18C6 and Cs+.DB18C6 complexes in aqueous solution, water molecules will preferentially bind on top of the boat conformers because of the displaced position of the metal ions relative to DB18C6. In contrast, the K+.DB18C6 complex can accept H2O molecules on both sides of the boat conformation. We also propose that the characteristic solvation manner of the K+.DB18C6 complex will contribute entropically to its high stability and thus to preferential capture of K+ ion by DB18C6 in solution.

AB - OBJECTIVE: To review and summarize data on angiotensin II (AT-II), approved by the Food and Drug Administration (FDA) in December 2017 to increase blood pressure in adults with septic or other distributive shock. DATA SOURCES: A PubMed/MEDLINE search was conducted using the following terms: (angiotensin ii OR angiotensin 2) AND (shock) from 1966 to February 2018. STUDY SELECTION AND DATA EXTRACTION: A total of 691 citations were reviewed with only relevant clinical data extracted. DATA SYNTHESIS: AT-II is a peptide hormone with a multitude of physiological effects-namely, vasoconstriction of venous and arterial smooth muscle. The priority approval granted by the FDA was secondary to a phase 3 study of patients receiving at least 0.2 ug/kg/min of norepinephrine or equivalent for vasodilatory shock. Compared with placebo, AT-II had a significantly higher rate of response, defined as a mean arterial pressure of 75 mm Hg or an increase of 10 mm Hg. No significant difference was found in death by day 28. CONCLUSIONS: AT-II is a newly available vasoactive agent with a novel mechanism for the treatment of distributive shock. Further research is needed to define its exact role in therapy of shock states, identify patients most likely to benefit, and further study its safety profile in critical illness. PMID- 29582667 TI - Ultrasound screening for abdominal aortic aneurysm: current practice, challenges and controversies. AB - The UK screening programme began in 2009, and has now been expanded around the UK. Long-term follow-up of the original cohorts continues to demonstrate significant benefits for abdominal aortic aneurysm (AAA)-related and all-cause mortality , and results from the first 5 years of the formal screening programme have demonstrated similar success. Ultrasound scanning is an effective and safe screening tool for the detection of AAA, although a variety of measurement protocols are employed internationally. Key challenges for the future of the programme relate to declining incidence of screen detected aneurysms. Recent publications have demonstrated a UK incidence of only 1.34%, compared to 4.9-7.2% of men invited for screening in the original trials. Work into increasing engagement amongst the target group, and expanding screening to siblings and women is underway to address this issue. This review describes the evidence behind the screening programme, its justification in addressing AAA as a significant health problem and discusses some of the potential developments in the future.

AB - BACKGROUND: An increasing amount of attention has been paid to minimally invasive function-preserving gastrectomy, with an increase in incidence of early gastric cancer in the upper stomach. This study aimed to compare oncological outcomes, surgical stress, and nutritional status between robot-assisted proximal gastrectomy (RAPG) and laparoscopy-assisted proximal gastrectomy (LAPG). METHODS: Eighty-nine patients were enrolled in this retrospective study between November 2011 and December 2013. Among them, 27 patients underwent RAPG and 62 underwent LAPG. Perioperative parameters, surgical stress, nutritional status, disease-free survival, and overall survival were compared between the 2 groups. RESULTS: Sex, age, and comorbidity were similar in the RAPG and LAPG groups. There were also similar perioperative outcomes regarding operation time, complications, and length of hospital stay between the groups. The reflux esophagitis rates following RAPG and LAPG were 18.5% and 14.5%, respectively ( P = .842). However, patients in the RAPG group had less blood loss ( P = .024), more harvested lymph nodes ( P = .021), and higher costs than those in the LAPG group ( P < .001). With regard to surgical stress, no significant differences were observed in C reactive protein concentrations and white blood cell count on postoperative days 1, 3, and 7 between the groups ( Ps > .05). There appeared to be higher hemoglobin levels at 6 months ( P = .053) and a higher body mass index at 12 months ( P = .056) postoperatively in patients in the RAPG group compared with those in the LAPG group, but this difference was not significant. Similar disease free survival and overall survival rates were observed between the groups. CONCLUSIONS: RAPG could be an alternative to LAPG for patients with early gastric cancer in the upper stomach with comparable oncological safety and nutritional status. Further well-designed, prospective, large-scale studies are needed to validate these results. PMID- 29582671 TI - A Standardized Method of Applying Toluidine Blue Metachromatic Staining for Assessment of Chondrogenesis. AB - Objectives Staining with toluidine blue is a well-established procedure for the histological assessment of cartilaginous- and chondrogenic-differentiated tissues. Being a cationic dye, toluidine blue staining visualizes proteoglycans in a tissue because of its high affinity for the sulfate groups in proteoglycans. It is generally accepted that metachromatic staining with toluidine blue represents cartilaginous matrix and that the degree of positive staining corresponds with the amount of proteoglycans. Design Articular cartilage and pellets of chondrocytes or bone marrow stromal cells were analyzed with a standardized staining procedure for toluidine blue. Results In the present study, we illustrate why such an assumption is invalid unless a detailed description of the procedure and/or reference to a detailed published method are provided. This is because the staining specificity and intensity depend, as we have shown, on the pH of the staining solution, the use of dehydration, and on staining time. Conclusions We can, therefore, suggest a well-controlled standardized protocol for toluidine blue staining, which provides an easy and simple selective staining technique for the assessment of cartilage tissue and proteoglycan development in chondrogenic differentiation. If this procedure is not used, then investigators must provide sufficient technical information concerning the staining protocol to allow an assessment of the validity of the staining results. PMID- 29582670 TI - Determining paediatric patient thickness from a single digital radiograph-a proof of principle. AB - OBJECTIVE: This work presents a proof of principle for a method of estimating the thickness of an attenuator from a single radiograph using the image, the exposure factors with which it was acquired and a priori knowledge of the characteristics of the X-ray unit and detector used for the exposure. It is intended this could be developed into a clinical tool to assist with paediatric patient dose audit, for which a measurement of patient size is required. METHODS: The proof of principle used measured pixel value and effective linear attenuation coefficient to estimate the thickness of a Solid Water attenuator. The kerma at the detector was estimated using a measurement of pixel value on the image and measured detector calibrations. The initial kerma was estimated using a lookup table of measured output values. The effective linear attenuation coefficient was measured for Solid Water at varying kVp. 11 test images of known and varying thicknesses of Solid Water were acquired at 60, 70 and 81 kVp. Estimates of attenuator thickness were made using the model and the results compared to the known thickness. RESULTS: Estimates of attenuator thickness made using the model differed from the known thickness by 3.8 mm (3.2%) on average, with a range of 0.5-10.8 mm (0.5-9%). CONCLUSION: A proof of principle is presented for a method of estimating the thickness of an attenuator using a single radiograph of the attenuator. The method has been shown to be accurate using a Solid Water attenuator, with a maximum difference between estimated and known attenuator thickness of 10.8 mm (9%). The method shows promise as a clinical tool for estimating abdominal paediatric patient thickness for paediatric patient dose audit, and is only contingent on the type of data routinely collected by Medical Physics departments. Advances in knowledge: A computational model has been created that is capable of accurately estimating the thickness of a uniform attenuator using only the radiographic image, the exposure factors with which it was acquired and a priori knowledge of the characteristics of the X-ray unit and detector used for the exposure.

AB - Purpose The present study investigated the effects of hyperbaric oxygen (HBO) on human chondrocyte proliferation and gene expression patterns. Methods Chondrocyte cultures were transferred to a HBO chamber and exposed to 100% oxygen for 7 consecutive days. Within groups, pressure was varied between 1 and 2 atm and duration of HBO administration was varied among 60, 90, and 120 minutes. Cell counts were performed using the WST-1 assay at 1, 3, 5, and 7 days after initiation of HBO treatment to obtain data to plot a growth curve. Gene expression of apoptosis markers PARP and caspase 3, as well as cartilage specific proteins collagen II and COMP, were detected by reverse transcription polymerase chain reaction. Results The experiments showed that in vitro administration of HBO inhibit chondrocyte growth. When applied compression was increased up to 2 atm, chondrocyte cell count was reduced by half at days 3 and 7 in association with an upregulation of the apoptosis markers PARP and caspase 3 as well as the cartilage specific proteins collagen II and COMP. No significant differences were monitored from varied duration of daily treatment. Conclusion Chondrocyte growth was inhibited in vitro by treatment of HBO. This inhibitory effect was even increased by elevating the applied pressure, while molecular testing showed reduced chondrocyte growth. Higher levels of HBO inhibited cell growth even more, but up-regulation of apoptosis specific markers and cartilage specific proteins were seen during administration of high oxygen levels. Thus, it has to be evaluated that there is a critical level of hypo-/hyperoxia required to stimulate or at least maintain chondrocyte cell proliferation. PMID- 29582673 TI - Effect of the CCL5-Releasing Fibrin Gel for Intervertebral Disc Regeneration. AB - Objective To explore if chemokine (C-C motif) ligand 5 (CCL5) delivery could recruit annulus fibrosus (AF) cells to the injury sites and facilitate the repair of ruptured AF. Design The effects of CCL5 on bovine AF cells in vitro were tested by transwell assay and quantitative real-time polymerase chain reaction. Fibrin gel containing CCL5 was used to treat annulotomized bovine caudal discs cultured under dynamic loading conditions. After 14 days of loading, the samples were collected for histological examination. A pilot animal study was performed using sheep cervical discs to investigate the effect of fibrin gel encapsulated with CCL5 for the treatment of ruptured AF. After 14 weeks, the animals were sacrificed, and the discs were scanned with magnetic resonance imaging before histopathological examination. Results CCL5 showed a chemotactic effect on AF cells in a dose-dependent manner. AF cells cultured with CCL5 in vitro did not show any change of the gene expression of CCL5 receptors, catabolic and proinflammatory markers. In vitro release study showed that CCL5 exhibited sustained release from the fibrin gel into the culture media; however, in the organ culture study CCL5 did not stimulate homing of AF cells toward the defect sites. The pilot animal study did not show any repair effect of CCL5. Conclusions CCL5 has a chemotactic effect on AF cells in vitro, but no ex vivo or in vivo regenerative effect when delivered within fibrin gel. Further study with a stronger chemotactic agent and/or an alternate biomaterial that is more conductive of cell migration is warranted. PMID- 29582674 TI - Current Procedural Terminology Coding for Surgical Pathology: A Review and One Academic Center's Experience With Pathologist-Verified Coding. AB - CONTEXT.-: The Current Procedural Terminology (CPT) system is a standardized numerical coding system for reporting medical procedures and services, and is the basis for reimbursement of health care providers by Medicare and other third party payers. Accurate CPT coding is therefore crucial for appropriate compensation as well as for compliance with Medicare policies, and erroneous coding may result in loss of revenues and/or significant monetary penalties for a hospital or practice. OBJECTIVE.-: To provide a review of the history, current state, and basic principles of CPT coding, in particular as it applies to the practice of surgical pathology, and to present our experience with initiating a new system of pathologist involvement in the review and verification of CPT codes, including the most common codes that require modification in our practice at the time of sign-out or post-sign-out auditing. DATA SOURCES.-: Review of English language literature, published CPT resources from the American Medical Association and other professional organizations, and billing quality data from a single institution. CONCLUSIONS.-: Although the appropriate extent of physician involvement in CPT coding is a matter of some debate, a multidisciplinary approach involving both health care providers and professional coders appears to be the best way to achieve accuracy. PMID- 29582675 TI - Feasibility of the Less Is More Approach in Treating Low-Risk Ductal Carcinoma In Situ Diagnosed on Core Needle Biopsy: Ten-Year Review of Ductal Carcinoma In Situ Upgraded to Invasion at Surgery. AB - CONTEXT: - Ductal carcinoma in situ (DCIS) represents 20% of screen-detected breast cancers. The likelihood that certain types of DCIS are slow growing and may never progress to invasion suggests that our current standards of treating DCIS could result in overtreatment. The LORIS (LOw RISk DCIS) and LORD (LOw Risk DCIS) trials address these concerns by randomizing patients with low-risk DCIS to either active surveillance or conventional treatment. OBJECTIVE: - To determine the upgrade rate of DCIS diagnosed on core needle biopsy to invasive carcinoma at surgery and to evaluate the safety of managing low-risk DCIS with surveillance alone, by characterizing the pathologic and clinical features of upgraded cases and applying criteria of the LORD and LORIS trials to these cases. DESIGN: - A 10 year retrospective analysis of DCIS on core needle biopsy with subsequent surgery. RESULTS: - We identified 1271 cases of DCIS on core needle biopsy: 200 (16%) low grade, 649 (51%) intermediate grade, and 422 (33%) high grade. Of the 1271 cases, we found an 8% upgrade rate to invasive carcinoma (n = 105). Nineteen of the 105 upgraded cases (18%) had positive lymph nodes. Low-grade DCIS was least likely to upgrade to invasion, comprising 10% (10 of 105) of upgraded cases. Three of the 105 upgraded cases (3%) met criteria for the LORD trial, and all were low-grade DCIS on core needle biopsy with favorable biology on follow up. CONCLUSIONS: - There is a clear risk of upgrade to invasion on follow-up excision; however, applying strict criteria of the LORD trial effectively decreases the likelihood of a missed invasive component or missed aggressive pathologic features. PMID- 29582676 TI - Factors Impacting the Performance Characteristics of Bile Duct Brushings: A Clinico-Cytopathologic Analysis of 253 Patients. AB - CONTEXT: - Literature on factors impacting bile duct brushings (BDBs) performance characteristics remain limited. OBJECTIVE: - To capture the current state of daily practice with BDB sign-out. DESIGN: - Two hundred fifty-three of 444 BDBs signed out by more than 7 cytopathologists, with histopathologic and/or clinical follow-up of at least 18 months, were examined. RESULTS: - One hundred thirty five of 253 BDBs (53%) had histologically confirmed malignancies, 22 (9%) had cancer-related deaths, and 96 (38%) were benign. Cytologic diagnoses in the 444 BDBs were nondiagnostic (11 [2.5%]), negative (284 [64%]), atypical (62 [13.9%]), suspicious (34 [7.7%]), and malignant (53 [11.9%]). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of malignancy detection were 35%, 100%, 100%, 58%, and 66%, respectively. When atypical, suspicious, and malignant (ASM) categories were combined, sensitivity increased (58%), specificity and PPV dropped (97%), and accuracy increased (73%). Carcinoma type (bile-duct versus pancreatic-ductal) had no effect on accuracy ( P = .60) or diagnostic class ( P = .84), nor did time of performance (first 7.5 versus latter 7.5 years, P = .13). Interestingly, ThinPrep + cell block (n = 41) had higher sensitivity (61%) and lower specificity (80%) than ThinPrep only (versus 51% and 100%, respectively). Sensitivity and specificity were higher (47% and 100%) in nonstented than stented specimens (59% and 97%). Relative risk of malignancy for "suspicious" (2.30) and "atypical" (2.28) categories was lower but not very different from that of "malignant" category (2.41). CONCLUSIONS: - Bile duct brushings had fairly low sensitivity but high specificity and PPV with no false positives. Sensitivity almost doubled and specificity dipped minimally when ASM categories were combined, highlighting the need for better classification criteria for atypical/suspicious cases. Higher specificity, PPV, NPV, and accuracy but lower sensitivity in stented BDBs suggest that they be called malignant only when evidence is overwhelmingly convincing. PMID- 29582677 TI - Noninvasive Follicular Thyroid Neoplasms With Papillary-like Nuclear Features Are Genetically and Biologically Similar to Adenomatous Nodules and Distinct From Papillary Thyroid Carcinomas With Extensive Follicular Growth. AB - CONTEXT: - Proposed noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTPs), formerly noninvasive encapsulated papillary carcinoma, follicular variant (PTC-FV), is an indolent tumor with follicular growth and frequent RAS mutations. OBJECTIVE: - To detect histologic and molecular differences separating NIFTP from follicular adenomas (FAs) and invasive carcinomas, particularly papillary carcinomas with extensive follicular growth (PTC-EFGs) and invasive encapsulated PTC-FV (IE-PTC-FV). DESIGN: - Sixty-one tumors were reviewed histologically and reclassified into 32 NIFTPs (52%), 4 IE PTC-FVs (7%), 14 PTC-EFGs (23%), and 11 FAs (18%). Next-generation sequencing for mutations in 50 genes was performed. Clinical outcomes were recorded. RESULTS: - The NIFTPs and FAs were well circumscribed and unencapsulated. The FAs had bland nuclei, whereas the NIFTPs showed at least 2 of 3 (67%; sufficient) nuclear features (enlargement, irregular contours, chromatin clearing). The IE-PTC-FVs had follicular growth, sufficient nuclear features, and extensive capsular invasion. The PTC-EFGs had a median of 5% papillae with intrathyroidal invasion (broad-based, sclerotic, or small follicle growth patterns); intranuclear pseudoinclusions were present only in PTC-EFGs (9 of 14; 64%). Mutations included RAS in 20 of the 32 NIFTPs (62%), 4 of the 11 FAs (36%), and 3 of the 4 IE-PTC FVs (75%); BRAF K601E in 1 NIFTP (3%); BRAF V600E in 5 PTC-EFGs (36%). No NIFTPs or FAs recurred or metastasized. All 4 IE-PTC-FVs (100%) had hematogenous metastasis. Two PTC-EFGs (14%) had lymphatic metastasis. CONCLUSIONS: - The morphologic similarity and RAS mutations in FAs, NIFTPs, and IE-PTC-FVs supports the genetic similarity of those follicular neoplasms in contrast to the unique presence of BRAF V600E mutations in PTC-EFGs. Using strict diagnostic criteria supported by molecular testing, tumors with extensive follicular growth can be classified into follicular type or RAS-like (FA, NIFTP, IE-PTC-FV) versus papillary type or BRAF V600E-like (PTC-EFG).

PMID- 29582679 TI - Does the real-time ultrasound guidance provide safer venipuncture in implantable venous port implantation? AB - AIM: To examine whether the real-time ultrasound-guided venipuncture for implantable venous port placement is safer than the traditional venipuncture. METHODS: The study analyzed the results of 2153 venous ports placed consecutively from January 2009 to January 2016. A total of 922 patients in group 1 and 1231 patients in group 2 were admitted with venous port placed using the traditional landmark subclavian approach and real-time ultrasound-guided axillary approach, respectively. Sociodemographic characteristics of patients, early (pneumothorax, pinch-off syndrome, arterial puncture, hematoma, and malposition arrhythmia) and late (deep vein thrombosis, obstruction, infection, erosion-dehiscence, and rotation of the port chamber) complications and the association of these complications with the implantation method were evaluated. RESULTS: There were no significant differences in the sociodemographic characteristics of the patients between the two groups. The overall and early complications in group 2 were significantly lower than those in group 1. Pinch-off syndrome only developed in group 1. Seven patients and two patients had pneumothorax in groups 1 and 2, respectively. Puncture number was significantly associated with the development of the overall complications. CONCLUSION: The ultrasound-guided axillary approach may be preferred as a method to reduce the risk of both early and late complications. Large, randomized, controlled prospective trials will be helpful in determining a safer implantable venous port implantation technique. PMID- 29582680 TI - Catheter-related complications and survival among incident hemodialysis patients in Singapore. AB - INTRODUCTION:: Hemodialysis is the main modality of renal replacement therapy in Singapore. However, a majority of the patients in Singapore are initiated on hemodialysis via a catheter. This study examines the complication rates and factors predicting catheter-related bloodstream infections and mortality rates in patients who were initiated on hemodialysis at our institution. METHODS:: This is a single-center retrospective analysis of incident hemodialysis patients who were initiated on renal replacement therapy between 1 January 2010 and 31 December 2012. Catheter-related bloodstream infection risk factors, organisms, and associated mortality were analyzed. RESULTS:: The catheter-related bloodstream infection and exit site infection incidence rates were 0.75 and 0.50 per 1000 catheter days, respectively. The mean duration to first catheter-related bloodstream infection episode was 182.47 +/- 144.04 catheter days. Prolonged catheter duration was found to be a risk factor for catheter-related bloodstream infection. Compared to patients initiated on dialysis via arteriovenous fistula, initiation of dialysis via catheter is strongly associated with increased mortality (6.0% vs 14.5%; p = 0.02). In particular, the presence of diabetes mellitus and development of catheter-related bloodstream infection was associated with increased mortality ( p = 0.04 and 0.05, respectively). In addition, patients who began hemodialysis before being seen by a nephrologist were associated with decreased mortality (3.4% vs 13.0%; p = 0.03). CONCLUSION:: In conclusion, prolonged duration of catheter insertion is found to be a risk factor for catheter-related bloodstream infection in hemodialysis patients, and its development is associated with increased mortality. Early referral to a nephrologist and creation of arteriovenous fistula in pre-end-stage renal disease patients are pivotal in improving the outcomes of patients.

PMID- 29582683 TI - Incidence, Risk Factors, and Treatment of Achilles Tendon Rupture in Patients With End-Stage Renal Disease. AB - BACKGROUND: Dialysis-dependent patients and kidney transplant recipients may be at increased risk for Achilles tendon rupture (ATR). METHODS: We studied Medicare patients with end-stage renal disease (ESRD) from 1999 through 2013. Patients were categorized as waitlisted for a transplant, not waitlisted, or received a transplant. We performed multivariate negative binomial regression using demographic characteristics, comorbidities, and year of study entry to estimate adjusted incidence rate ratios (aIRRs), identify ATR risk factors, and determine treatment patterns and outcomes. RESULTS: We identified 1091 ATRs (incidence, 3.80/10 000 person-years; 95% confidence interval [CI], 3.58-4.03). Compared with transplant recipients, nonwaitlisted patients had a lower incidence (aIRR, 0.44; 95% CI, 0.37-0.53), and waitlisted patients had a similar incidence (aIRR, 0.94; 95% CI, 0.78-1.12) of ATR. ATR incidence was higher among patients taking fluoroquinolones (aIRR, 1.65; 95% CI, 1.32-1.84) and corticosteroids (aIRR, 1.72; 95% CI, 1.44-2.05) compared with those who did not. Patients with ATR were younger, had higher mean body mass index, and had fewer comorbidities than patients without ATR. Seventeen percent of patients received operative treatment within 14 days of ATR diagnosis. The 30-day cumulative incidence of operative site infections was 6.5%. CONCLUSION: The incidence of ATR was higher among transplant recipients and waitlisted patients compared with nonwaitlisted patients. Younger age, higher body mass index, fewer comorbidities, fluoroquinolone use, and corticosteroid use were risk factors for ATR. Patients were more likely to receive nonoperative than operative treatment for ATR. Those who underwent operative treatment had a low incidence of operative site infection. LEVEL OF EVIDENCE: Prognostic level III, comparative study. PMID- 29582684 TI - Strength of Interference Screw Fixation to Cuboid vs Pulvertaft Weave to Peroneus Brevis for Tibialis Posterior Tendon Transfer for Foot Drop. AB - BACKGROUND: Tibialis posterior (TP) tendon transfer is an effective treatment for foot drop. Currently, standard practice is to immobilize the ankle in a cast for 6 weeks nonweightbearing, risking postoperative stiffness. To assess whether early active dorsiflexion and protected weightbearing could be safe, the current study assessed tendon displacement under cyclic loading and load to failure, comparing the Pulvertaft weave (PW) to interference screw fixation (ISF) in a cadaveric foot model. METHODS: Twenty-four cadaveric ankles had TP tendon transfer performed, 12 with the PW technique and 12 with ISF to the cuboid. The TP tendon was cycled 1000 times at 50 to 150 N and then loaded to failure in a materials testing machine. Tendon displacement at the insertion site was recorded every 100 cycles. An independent t test and 2-way analysis of variance were performed to compare techniques, with a significance level of P < .05. RESULTS: Mean tendon displacement was similar in the PW group (2.9 +/- 2.5 mm [mean +/- SD]) compared with the ISF group (2.4 +/- 1.1 mm), P = .35. One specimen in the ISF group failed early by tendon pullout. None of the PW group failed early, although displacement of 8.9 mm was observed in 1 specimen. Mean load to failure was 419.1 +/- 82.6 N in the PW group in comparison to 499.4 +/- 109.6 N in the ISF group, P = .06. CONCLUSION: For TP tendon transfer, ISF and PW techniques were comparable, with no differences in tendon displacement after cyclical loading or load to failure. Greater variability was observed in the PW group, suggesting it may be a less reliable technique. CLINICAL RELEVANCE: The results indicate that early active dorsiflexion and protected weightbearing may be safe for clinical evaluation, with potential benefits for the patient compared with cast immobilization. PMID- 29582685 TI - 'Real-life' experience with direct-acting antiviral agents for hepatitis C virus in end-stage renal disease. AB - BACKGROUND AND AIMS: The advent of direct-acting antiviral agents promises to change the management of hepatitis C in patients with end-stage renal disease, a patient group where the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a 'real-world' group of patients with end-stage renal disease. METHODS: We performed a single-arm, multi centre study in a cohort (n=30) of patients with advanced chronic kidney disease (mostly on dialysis) who underwent antiviral therapy with direct-acting antiviral agents. The primary end-point was sustained virologic response (serum hepatitis C virus RNA < 15 mIU/mL, 12 weeks after treatment ended). We collected data on on treatment adverse events, serious adverse events and laboratory abnormalities. RESULTS: In total, 23 (77%) and 7 (23%) patients underwent regular dialysis and had chronic kidney disease at pre-dialysis stage, respectively. Six regimens were adopted: elbasvir/grazoprevir ( n = 6), ledipasvir/sofosbuvir +/- ribavirin ( n = 4), PrOD regimens +/- ribavirin ( n = 10), simeprevir + daclatasvir ( n = 3), sofosbuvir + daclatasvir +/- ribavirin ( n = 3), sofosbuvir + ribavirin ( n = 4). The SVR12 rate was 90% (95% confidence interval, 74%; 96%). A total of 27 (90%) patients achieved SVR12; there were three virologic failures - two were non responders and one had a viral breakthrough while on therapy. Adverse events occurred in 53% (16/30) (95% confidence interval, 0.39; 0.73) of patients and were managed clinically without discontinuation of therapy or hospitalization. The most common adverse event was anaemia ( n = 12) that required blood transfusions in seven individuals; deterioration of kidney function occurred in one (14%). CONCLUSION: All-oral, interferon-free therapy with direct-acting antiviral agents for chronic hepatitis C virus in advanced chronic kidney disease was effective and well tolerated in a 'real-life' clinical setting. Careful monitoring of haemoglobin and serum creatinine during therapy with direct-acting antiviral agents is suggested. Studies are under way to address whether sustained viral response translates into better survival in this population. PMID- 29582686 TI - The effects of radiotherapy on the survival of patients with unresectable non small cell lung cancer. AB - INTRODUCTION: Lung cancer represents the leading cause of cancer mortality across the worlds. At present, less than 30% of the patients can undergo curative surgery, while the majority of them (65%) are diagnosed with metastatic disease and directed to systemic treatments. In this context there is a subset of patients (25%) with locally advanced stage disease whose outcome might be improved by using combined strategies of treatment including chemotherapy, radiotherapy and surgery. Areas covered: Here we reviewed possible combination strategies aimed to improve the outcome of lung cancer patients, focusing on the role of radiotherapy both in the adjuvant and oligo-metastatic setting and in synergy with immunotherapy, and finally, we afforded the new challenges concerning the advanced RT and precision oncology. We carried out a focused analysis concerning the key clinical management weaknesses as well as the potential that current research holds. Expert commentary: We believe that the most promising clinical trials in this specific patient subset will build their rationale on the results of well-designed translational models aimed to test the combination of cytotoxic drugs, radiobiology, and immune-pharmacology. In this context, remarkable investigational fields are focused on the attempt to combine radiotherapy with chemo-immunological strategies and precision medicine protocols. PMID- 29582688 TI - The politics and practice of Thomas Adeoye Lambo: towards a post-colonial history of transcultural psychiatry. AB - This article traces the career of Thomas Adeoye Lambo, the first European-trained psychiatrist of indigenous Nigerian (Yoruba) background and one of the key contributors to the international development of transcultural psychiatry from the 1950s to the 1980s. The focus on Lambo provides some political, cultural and geographical balance to the broader history of transcultural psychiatry by emphasizing the contributions to transcultural psychiatric knowledge that have emerged from a particular non-western context. At the same time, an examination of Lambo's legacy allows historians to see the limitations of transcultural psychiatry's influence over time. Ultimately, this article concludes that the history of transcultural psychiatry might have more to tell us about the politics of the 'transcultural' than the practice of 'psychiatry' in post-colonial contexts. PMID- 29582687 TI - Dual method use among long-acting reversible contraceptive users. AB - OBJECTIVE: To compare rates of dual method use (concurrent use of condoms and an effective method of contraception) in long-acting reversible contraceptive (LARC) and non-LARC hormonal contraceptive users, and to determine factors associated with dual method use. METHODS: We conducted a secondary analysis of the Contraceptive CHOICE Project, an observational, prospective cohort study of 9256 women in St. Louis, MO, USA. Our sample included 6744 women who initiated a contraceptive method within 3 months of enrollment, continued use at 6 months post-enrollment, and responded regarding dual method use. Our primary outcome was the rate of dual method use at 6 months post-enrollment. RESULTS: Dual method use was reported by 32% of LARC and 45% of non-LARC hormonal contraceptive users (p < .01). After adjusting for other covariates and comparing to non-LARC hormonal contraceptive users, LARC users were less likely to report dual method use (RRadj 0.76, 95% CI 0.70-0.83). Factors associated with dual method use in our multivariable analysis were age <25 years, black race, lower education, single relationship status, baseline dual method use, baseline diagnosis of sexually transmitted infection (STI), greater partner willingness to use a condom, and higher condom self-efficacy score. CONCLUSIONS: LARC users are less likely to report dual method use compared to non-LARC hormonal contraceptive users, but other factors also impact dual method use. Further studies should be performed to determine whether this lower dual method use increases the risk of STI. CLINICAL TRIALS REGISTRATION: Clinicaltrials.gov Identifier NCT01986439. PMID- 29582690 TI - Olaparib for the treatment of breast cancer. AB - INTRODUCTION: Mutations in BRCA1 and BRCA2 genes account for around 2-3% of breast cancer events and more than 10% of triple negative breast cancers. Olaparib (Lynparza(r)), an orally administered PARP inhibitor, demonstrated clinical benefit in a phase III trial for mutated BRCA-positive HER2 negative metastatic breast cancer. Areas covered: This review gives an overview of available preclinical and clinical data regarding olaparib, including its chemistry, mechanism of action, pharmacokinetics and pharmacodynamics, and evidence supporting antitumor efficacy and safety profile in breast cancer patients. Expert commentary: Olaparib improves progression-free survival in germline BRCA mutated HER2 negative metastatic breast cancer patients as compared to standard chemotherapy, with a manageable toxicity profile. Efficacy is of clinical relevance especially in the context of triple negative breast cancer. However, several aspects, such as sequencing or combination of these agents with other anticancer agents and identification of appropriate biomarkers, still need to be clearly defined. PMID- 29582689 TI - Metallic materials in the exomass impair cone beam CT voxel values. AB - OBJECTIVES: To assess the influence of artefacts arising from metallic materials in the exomass on cone beam CT (CBCT) voxel values. METHODS: CBCT scans were taken of a phantom composed of 16 tubes filled with a homogeneous hyperdense solution and metallic materials of different compositions (titanium, cobalt chromium and amalgam) and numbers (one, two and three). The phantom was centred in a 5 * 5 cm field of view such that the metallic materials were located in the exomass, using three CBCT units. Voxel values were obtained from the 16 homogeneous areas and averaged. Also, standard deviation was calculated to measure voxel value variability. Analysis of variance in a factorial scheme with additional treatment 3 * 3 + 3 (material * number + control) was performed, followed by Tukey's test for multiple comparisons, and Dunnett's test for comparisons with the control groups, at a level of significance of 5%. RESULTS: Metallic material in the exomass significantly reduced the mean voxel value in the CS9300 and Picasso Trio units, and increased voxel value variability in all CBCT units. Amalgam was the material that induced significantly greater reduction of the mean voxel value in the CS9300 and Picasso Trio units, and significantly greater increase in the NewTom Giano. Voxel value variability was significantly greater for amalgam in all conditions. The presence of one cylinder induced significantly less pronounced effects on the mean voxel value and voxel value variability. CONCLUSIONS: Artefacts arising from metallic materials in the exomass have a negative influence on CBCT voxel values. PMID- 29582691 TI - Eric Wittkower and the foundation of Montreal's Transcultural Psychiatry Research Unit after World War II. AB - Eric Wittkower founded McGill University's Transcultural Psychiatry Unit in 1955. One year later, he started the first international newsletter in this academic field: Transcultural Psychiatry. However, at the beginning of his career Wittkower gave no signs that he would be interested in social sciences and psychiatry. This paper describes the historical context of the post-war period, when Wittkower founded the research unit in Montreal. I focus on the history of scientific networks and the circulation of knowledge, and particularly on the exchanges between the French- and English-speaking academic cultures in North America and Europe. Because the history of transcultural psychiatry is a transnational history par excellence, this leads necessarily to the question of the reception of this academic field abroad. PMID- 29582692 TI - Differential effects of epidermal growth factor (EGF) receptor ligands on receptor binding, downstream signalling pathways and DNA synthesis in hepatocytes. AB - Hepatocytes are responsive to mitogenic effects of several ligands acting via EGFR. Studying primary cultures of rat hepatocytes, we found that, as compared to EGF, HB-EGF had a markedly higher affinity of the EGFR, while AR and TGFalpha had lower affinity. HB-EGF was also more potent compared to the other growth factors regarding phosphorylation of EGFR, Shc, ERK1/2 and Akt. All ligands induced phosphorylation of ErbB2, indicating receptor heterodimerization. TGFalpha, despite having much lower receptor affinity, was about equally potent and efficacious as HB-EGF as a stimulator of DNA synthesis. In contrast, EGF had relatively high affinity but markedly lower efficacy in stimulation of DNA synthesis. The results suggest that amplifying and/or inhibitory mechanisms may modulate the mitogenic responses downstream of the initial signalling steps, and that this may affect the effects of the EGFR ligands differentially. PMID- 29582693 TI - A theoretical analysis and finite element simulation of fixator-bone system stiffness on healing progression. AB - INTRODUCTION: The unilateral external fixator has become a quick and easy application for fracture stabilization of the extremities; the main value for evaluation of mechanical stability of the external fixator is stiffness. The stiffness property of the external fixator affects the local biomechanical environment of fractured bone. METHODS: In this study, a theoretical model with changing Young's modulus of the callus is established by using the Castigliano's theory, investigating compression stiffness, torsional stiffness and bending stiffness of the fixator-bone system during the healing process. The effects of pin deviation angle on three stiffness methods are also investigated. In addition, finite element simulation is discussed regarding the stress distribution between the fixator and bone. RESULTS: The results reveal the three stiffness evaluation methods are similar for the fixator-bone system. Finite element simulation shows that with increased healing time, the transmission of the load between the fixator and bone are different. In addition, the finite element analyses verify the conclusions obtained from the theoretical model. CONCLUSIONS: This work helps orthopedic doctors to monitor the progression of fracture healing and determine the appropriate time for removal of a fixation device and provide important theoretical methodology. PMID- 29582694 TI - Anconeus Epitrochlearis Muscle Associated With Cubital Tunnel Syndrome: A Case Series. AB - BACKGROUND: Cubital tunnel syndrome is a common compressive neuropathy of the upper extremity. The anconeus epitrochlearis muscle is an unusual but occasional contributor. We review our experience with this anomalous muscle in elbows with cubital tunnel syndrome. METHODS: We retrospectively reviewed charts of 13 patients noted to have an anconeus epitrochlearis muscle associated with cubital tunnel syndrome. RESULTS: Ten patients had unilateral ulnar neuropathy supported by nerve conduction studies. Three had bilateral cubital tunnel syndrome symptoms with 1 of those having normal nerve conduction studies for both elbows. Eight elbows were treated with myotomy of the anconeus epitrochlearis muscle and submuscular transposition of the ulnar nerve. The other 8 elbows were treated with myotomy of the anconeus epitrochlearis muscle and in situ decompression of the ulnar nerve only. All but 1 patient had either clinical resolution or improvement of symptoms at follow-up ranging from 2 weeks to 1 year after surgery. The 1 patient who had persistent symptoms had received myotomy and in situ decompression of the ulnar nerve only. CONCLUSIONS: An anomalous anconeus epitrochlearis occasionally results in compression of the ulnar nerve but is usually an incidental finding. Its contribution to compression neuropathy can be tested intraoperatively by passively ranging the elbow while observing the change in vector and tension of its muscle fibers over the ulnar nerve. Regardless of findings, we recommend myotomy of the muscle and in situ decompression of the ulnar nerve. Submuscular transposition of the ulnar nerve may be necessary if there is subluxation. PMID- 29582695 TI - Development of a pressure sensor system for unobtrusive monitoring of abdominal muscle activities. AB - Surface electromyogram (sEMG) is often used by to objectively measure muscular activity during rehabilitation exercises. sEMG is accurate, but it is unsuitable for uses outside the clinic, and patients can benefit from an unobtrusive device which can be readily used to ubiquitously measure abdominal muscle activation. In this study, we present a pressure sensor system which can be latched onto a belt to measure abdominal muscle activation. sEMG and pressure sensor output were measured in 15 healthy young males during isometric trunk flexion exercise (public trials registration number, KCT0002351), and the results were highly correlated (median R > 0.939). As initial contact force can change the pressure sensor sensitivity, the experiment was performed at two different levels of belt tightness, but the correlations did not significantly improve after tightening the belt, suggesting that the system can be used to ubiquitously and unobtrusively monitor abdominal muscle activity with minimal discomfort.

AB - INTRODUCTION: the high expression of a number of surface antigens on malignant plasma cells, the bone marrow micro-environment and immune effector T cells, makes these appealing targets for immune therapy with monoclonal antibodies (mAbs). Areas covered: Two mAbs, anti-CD38 daratumumab (Dara) and anti-SLAMF7 elotuzumab (Elo), have achieved recent regulatory approval for relapsed or refractory MM (RRMM) and are currently being explored as possible treatment options in novel combinations and different settings. This review discusses the current landscape and possible development of anti-CD38 and anti-SLAMF7 mAbs. Expert commentary: Three phase III trials demonstrated a significant advantage in terms of response and PFS when Dara or Elo are combined with lenalidomide dexamethsone (Rd) or bortezomib-dexamethsone (Vd), in comparison to doublet regimens, for patients with RRMM. Treatment algorithms including Dara- or Elo based triplets may be defined on the basis of disease and patients' characteristics, as well as of their prior exposure to different classes of novel agents. Evaluation of these agents in new combination regimens, including second and third generation PIs and IMiDs, are under investigation. Moreover, use of mAbs in phases of the disease where the immune system is less compromised, such as newly diagnosed MM or even high-risk smoldering myeloma, appears logical.

AB - The COBRA-PzFTM (CeloNova BioSciences, Inc., TX, USA) is a new type of coronary stent composed of a cobalt chromium metallic backbone surrounded by a nanothin layer of Polyzene-F (PzF) without any added drug. Evidence from basic studies supports antithrombotic and anti-inflammatory properties for the PzF surface coating. Preclinical studies support the thromboresistance of PzF-coated surfaces and clinical studies have shown good outcomes for patients receiving this device with very low rates of stent thrombosis. COBRA-PzF may be especially useful in patients at high risk for bleeding. Ongoing clinical trials will determine whether shortening the duration of dual antiplatelet therapy to less than 1 month is feasible and these data may represent a new paradigm with regards to patients at high risk for bleeding. PMID- 29582699 TI - Strong immunoexpression of dickkopf-1 is associated with response to bortezomib in multiple myeloma. AB - The predictive significance of osteolysis-related proteins was evaluated in bortezomib-treated multiple myeloma. The clinicopathological characteristics were collected retrospectively. Immunohistochemistry was performed for analyzing receptor activator of NF-kappaB ligand (RANKL), osteoprotegerin (OPG), macrophage inflammatory protein 1 alpha (MIP1alpha), and dickkopf-1 (DKK1) expression. Among clinicopatholgical characteristics, osteolytic lesion was associated with higher response to bortezomib treatment (79% vs. 46%). High DKK1 expression was significantly correlated with osteolytic lesion (p = .003), whereas RANKL, OPG, and MIP1alpha were not. In high DKK1 expression, higher response to bortezomib was observed (84% vs. 44%). In multivariate analysis, high DKK1 expression was associated with better response to bortezomib (p = .005). Patients with high DKK1 expression had longer median progression-free survival (PFS) and overall survival (OS) after bortezomib treatment. In multivariate analysis, high DKK1 expression was an independent prognostic factor of favorable PFS (p = .027) and OS (p = .035). In multiple myeloma treated with bortezomib, expression status of DKK1 may be a useful predictive marker. PMID- 29582700 TI - Reducing Surgical Revisions in Intracranial Complications of Pediatric Acute Sinusitis. AB - Objective (1) To describe the demographics and clinical course of children with intracranial complications of sinusitis. (2) To elucidate factors that predict revision surgery in this population, such as type of initial surgery. Study Design Case series with chart review. Setting Tertiary care academic children's hospital. Subjects and Methods A 15-year retrospective review identified 71 patients with intracranial complications of acute sinusitis. Primary outcome was need for revision surgery. Secondary outcomes were readmission, length of hospitalization, and long-term complications. Results This study is the largest to date examining this disease process. Overall, 69 (97%) patients had surgery; 33 (46%) required revision surgery. Half of the patients with frontal sinus opacification underwent frontal sinus surgery at presentation (endoscopic, trephination, or cranialization). There was no difference in revision surgery between patients who had frontal sinus surgery and those who did not. Patients with frontal sinus surgery did not have a higher rate of complications or chronic sinusitis ( P > .05). Subdural abscess was associated with multiple surgical procedures (odds ratio, 20.0; P < .01). Thirty-four patients (49%) required neurosurgery. These patients had a longer length of stay (odds ratio, 11.0; P < .01) and a higher readmission rate ( P = .02). During the mean 92-month follow up, 22 patients (33%) had long-term complications, and there was 1 death (1.4%). Conclusion Almost half of this cohort required multiple surgical procedures. In particular, patients with subdural abscess had significantly higher rates of revision surgery. Type of frontal sinus surgery was not correlated with need for revision surgery and was not associated with an increased rate of complications.

AB - Workplace bullying (WB) is an increasingly prevalent topic in the nursing literature. Recently, a new concept has been introduced into WB research to explain the motivations of WB instigators using elements of the Power-Control Wheel (PCW). Initially, this wheel was designed to assist intimate partner violence (IPV) targets/victims identify patterns of abuse and intervene with male batterers/instigators. Research examining IPV and victims/survivors of WB demonstrate that targets often share common abusive experiences, including intimidation, coercion and threats, isolation, and economic and emotional abuse. This article demonstrates clear support for the Duluth Model and its application to WB target experiences. Applications of this model to identify WB and assist individuals to identify and describe experiences of abusive work environments are discussed. PMID- 29582702 TI - Secular changes in the association between advanced maternal age and the risk of low birth weight: A cross-cohort comparison in the UK. AB - Existing studies provide contradictory evidence concerning the association between child health and advanced maternal age. A potential explanation for the lack of consensus on this issue is changes over time in the costs and benefits of giving birth at an advanced age. This is the first study to investigate secular changes in the characteristics of older mothers and in the association between advanced maternal age and child health. We use data from four UK cohort studies, covering births from 1958 to 2001, and use low birth weight (LBW) as a marker for child health. We find that across successive birth cohorts, the negative association between advanced maternal age and LBW becomes progressively weaker; and that this pattern is partially explained by secular changes in the characteristics of older mothers. Our results suggest that associations between maternal age and child outcomes are tied to a specific population and point in time. PMID- 29582703 TI - Upper Airway Stimulation for Obstructive Sleep Apnea: 5-Year Outcomes. AB - Objective To present 5-year outcomes from a prospective cohort of patients with obstructive sleep apnea (OSA) who were treated with upper airway stimulation (UAS) via a unilateral hypoglossal nerve implant. Study Design A multicenter prospective cohort study. Setting Industry-supported multicenter academic and clinical trial. Methods From a cohort of 126 patients, 97 completed protocol, and 71 consented to a voluntary polysomnogram. Those having continuous positive airway pressure failure with moderate to severe OSA, body mass index <32 kg/m2, and no unfavorable collapse on drug-induced sleep endoscopy were enrolled in a phase 3 trial. Prospective outcomes included apnea-hypopnea index (AHI), oxygen desaturation index, and adverse events, as well as measures of sleepiness, quality of life, and snoring. Results Patients who did and did not complete the protocol differed in baseline AHI, oxygen desaturation index, and Functional Outcomes of Sleep Questionnaire scores but not in any other demographics or treatment response measures. Improvement in sleepiness (Epworth Sleepiness Scale) and quality of life was observed, with normalization of scores increasing from 33% to 78% and 15% to 67%, respectively. AHI response rate (AHI <20 events per hour and >50% reduction) was 75% (n = 71). When a last observation carried forward analysis was applied, the responder rate was 63% at 5 years. Serious device-related events all related to lead/device adjustments were reported in 6% of patients. Conclusions Improvements in sleepiness, quality of life, and respiratory outcomes are observed with 5 years of UAS. Serious adverse events are uncommon. UAS is a nonanatomic surgical treatment with long-term benefit for individuals with moderate to severe OSA who have failed nasal continuous positive airway pressure. PMID- 29582704 TI - Maternal sensitivity in rural Andean and Amazonian Peru. AB - In the current study, we observed 12 mothers with a 4-21-month-old infant during their daily activities for around 3 h per dyad, focusing on daily caregiving practices such as feeding, bathing, and soothing in the rural multiple-caregiver cultural contexts of the Andean and Amazonian parts of Peru. Overall, sensitivity levels were high, with an average of 7.33 (out of 9), and 7 out of the 12 mothers scoring in the high range (scores 7-9), and the remaining 5 in the good-enough range (scores 5-6). In-depth descriptions of mother-infant interactions show that these high sensitivity levels reflect mothers' ability to multitask, combining household and agricultural chores with high sensitive responsiveness to their infants' signals. The presence of multiple caregivers seemed to allow mothers to make sure the infants were well attended when they were temporarily unavailable but combined with quick renewed availability if the infant seemed to need maternal proximity. PMID- 29582706 TI - Predictors of sensitive parenting in urban slums in Makassar, Indonesia. AB - In the context of urban slums in Makassar in Indonesia, this study aimed to test whether maternal sensitivity was predicted by maternal history of childhood maltreatment, and whether this association was mediated by current partner conflict and current cumulative sociodemographic risk. A total of 98 mothers and their 2-4-year-old children were videotaped in a naturalistic observation. Maternal sensitivity was coded using the Ainsworth scales. In addition, mothers were interviewed to assess childhood trauma, current partner conflict, and current sociodemographic risk. There was a significant negative correlation between maternal experienced childhood maltreatment and observed maternal sensitivity. Current partner conflict and sociodemographic risk did not mediate the association between childhood maltreatment and maternal sensitivity. PMID- 29582705 TI - Comparative assessment of prophylactic transfusions of platelet concentrates obtained by the PRP or buffy-coat methods, in patients undergoing allogeneic hematopoietic stem cell transplantation. AB - OBJECTIVES: Whole blood-derived platelet concentrates can be obtained by the platelet-rich plasma (PRP-PCs) or the buffy-coat (BC-PCs) method. Few studies have shown that BC-PCs display lower in vitro platelet activation, but scarce information exists regarding transfusion efficacy. We have performed a retrospective study assessing platelet transfusion in patients undergoing allogeneic hematopoietic cell transplantation (AHCT) in our clinic, before and after the implementation of BC-PCs. METHODS: We reviewed clinical records corresponding to 70 PRP-PCs and 86 BC-PCs prophylactic transfusions, which were performed to 55 AHCT patients. Transfusion efficacy was assessed by the 24-h post transfusion corrected count increment (24-h CCI) and bleeding events. Clinical factors affecting transfusion outcome were also investigated. RESULTS: Clinical characteristics and the total number of platelet transfusions were similar among groups. Mean donor exposure was 5.8 and 5.0 in each single PRP-PCs and BC-PCs transfusion, respectively (p < 0.01). The 24-h CCI was significantly higher in patients transfused with BC-PCs than in those receiving PRP-PCs (8.3[2.7-13.4] vs. 4.7[1.3-8.1]; p < 0.01). Independent predictors of poor platelet transfusion response included diagnosis other than acute leukemia (HR 8.30; 95% CI 1.96 35.22; p = 0.004), splenomegaly (HR 8.75; 95% CI 2.77-27.60; p < 0.001), graft versus host disease prophylaxis different from cyclosporine A and methotrexate (HR 3.96; 95% CI 1.55-10.14; p = 0.004) and PRP-PCs transfusion (HR 4.54; 95% CI 1.72-12.01; p = 0.002). There were no differences between both groups regarding the bleeding events. CONCLUSION: In the AHCT setting, we hypothesize that BC-PCs transfusion, when compared to PRP-PCs, results in higher CCI and reduced donor exposure, but provides no significant benefit regarding bleeding outcome. PMID- 29582707 TI - Decentralisation of Brazil's HIV/AIDS programme: intended and unintended consequences. AB - Brazil's response to the HIV/AIDS epidemic was characterised by an innovative alliance of governmental and non-governmental actors inspired by a strong progressive tradition in public health. Brazil eventually moved to decentralise HIV/AIDS programmes to its states and cities, a policy endorsed and supported financially by the World Bank as consistent with the mix of public and private elements central to the country's HIV/AIDS strategy. However, decentralisation has not provided the results anticipated. Through interviews with key informants, government officials and patient advocates as well as observation of treatment sites, we outline how the shift of administration and resources to state and municipal bodies operated in practice. The Bank promoted decentralisation as an uncontroversial technical matter, and its programmatic guidelines implied that the nonprofit sector would be strengthened by it. However, instead of bringing HIV/AIDS policy closer to the grassroots, decentralisation has undermined the country's early work and opened the door to a rejuvenated epidemic by empowering unsympathetic local elites, marginalising the human rights focus, and removing federal oversight. Its experience holds crucial lessons for developing countries facing similar conditions. PMID- 29582708 TI - Peritoneal and scrotal carcinomas of unknown origin in two bovine calves. AB - Two unrelated bovine beef calves, aged 2 mo and 3 mo, were presented to The Ohio State University Veterinary Medical Center because of scrotal swelling and abdominal distension. On postmortem examination, there was abundant peritoneal fluid and numerous small friable masses covering all peritoneal surfaces and extending into the scrotum via the tunica vaginalis, with no identifiable primary neoplasm. Based on light microscopy, differential diagnoses included malignant mesothelioma and anaplastic carcinoma. Immunohistochemically, the neoplasms labeled positive for cytokeratin, and negative for vimentin and calretinin. Neoplastic cells contained periodic acid-Schiff-positive, diastase-resistant cytoplasmic granules, and lacked Alcian blue-positive, hyaluronidase-negative cytoplasmic vacuoles. Ultrastructurally, the cells had features of carcinoma, including secretory granules, and lacked typical features of mesothelioma, such as long slender microvilli. Our final diagnosis was carcinoma in both calves, despite the equivocal gross and light microscopic findings. We propose that a presumptive diagnosis of peritoneal mesothelioma in bovine calves should be avoided without corroboration by a combination of histology, histochemistry, immunohistochemistry, and, if possible, electron microscopy. PMID- 29582709 TI - Adenoviral hemorrhagic disease in California mule deer, 1990-2014. AB - We reviewed case records from the California Animal Health and Food Safety (CAHFS) laboratory and the California Department of Fish and Wildlife (CDFW) spanning 25 years (1990-2014) for all deer accessions submitted to CAHFS for pathology and/or histopathology, with and without a diagnosis of adenoviral hemorrhagic disease (AHD), in order to determine the prevalence of AHD in California. We also examined spatial and temporal distribution, age, and mule deer subspecies in deer that died from AHD. Of 483 deer submitted to CAHFS for diagnostic testing in 1990-2014, 17.2% were diagnosed with confirmed AHD, and 26.5% were confirmed plus suspected cases of AHD. Columbian black-tailed deer ( Odocoileus hemionus columbianus), particularly fawns and juveniles, were most frequently affected. Deer adenovirus ( Odocoileus adenovirus 1; OdAdV-1) was detected by immunohistochemistry in archived CDFW formalin-fixed, paraffin embedded tissues from deer that died in mortality events in 1981, 1983, and 1986 1987. OdAdV-1 is a common cause of hemorrhagic disease mortality events in California deer, and mortality as a result of AHD is documented as early as 1981. PMID- 29582710 TI - Dosing characteristics of oral treprostinil in real-world clinical practice. AB - Pharmacokinetic studies with oral treprostinil demonstrate that three times daily (TID) dosing reduces peak-to-trough plasma trepostinil fluctuations compared with twice daily (BID) dosing. TID dosing may allow for faster titration, higher total daily doses, and potentially improve the tolerability of oral trepostinil. This analysis, which looks at the real-world dosing of oral treprostinil, supports the utility of TID dosing. PMID- 29582711 TI - The role of path length- and speed-related factors for the enhancement of section performance in alpine giant slalom. AB - Knowing how to enhance alpine skiing performance is essential for effective coaching. The purpose of this study was to explore the role of path length- and speed-related factors for performance enhancement, while skiing on a homogeneously set/constantly inclined giant slalom course section (average gate distance: 27 m; offset: 8 m; slope inclination: 26 degrees ). During a video based three-dimensional kinematic field-experiment, the data of six athletes who skied a two-gate section on four different types of skis were collected. The performance parameter analysed was section time. The performance predictors analysed were centre of mass (CoM), path length and the change in specific mechanical energy per entrance speed along the analysed section. Furthermore, since the current study examined alpine skiing performance within short sections, the skier's entrance speed was also considered. Classified as a high-performance and a low-performance group based on section time, slow and fast trials significantly differed in CoM path length, the change in specific mechanical energy per entrance speed and entrance speed. The entrance speed of all trials analysed ranged between 15.25 and 17.66 m/s. In trials with both high and low entrance speed, the change in specific mechanical energy per entrance speed was found to be more relevant for the prediction of section time than CoM path length. However, further studies should investigate whether such a prioritization can be unrestrictedly generalized to other situations, such as entrance speeds, course sets, slope inclinations and competition disciplines different to those assessed in the current study. PMID- 29582712 TI - Why do stroke survivors not receive recommended amounts of active therapy? Findings from the ReAcT study, a mixed-methods case-study evaluation in eight stroke units. AB - OBJECTIVE: To identify why the National Clinical Guideline recommendation of 45 minutes of each appropriate therapy daily is not met in many English stroke units. DESIGN: Mixed-methods case-study evaluation, including modified process mapping, non-participant observations of service organisation and therapy delivery, documentary analysis and semi-structured interviews. SETTING: Eight stroke units in four English regions. SUBJECTS: Seventy-seven patients with stroke, 53 carers and 197 stroke unit staff were observed; 49 patients, 50 carers and 131 staff participants were interviewed. RESULTS: Over 1000 hours of non participant observations and 433 patient-specific therapy observations were undertaken. The most significant factor influencing amount and frequency of therapy provided was the time therapists routinely spent, individually and collectively, in information exchange. Patient factors, including fatigue and tolerance influenced therapists' decisions about frequency and intensity, typically resulting in adaptation of therapy rather than no provision. Limited use of individual patient therapy timetables was evident. Therapist staffing levels were associated with differences in therapy provision but were not the main determinant of intensity and frequency. Few therapists demonstrated understanding of the evidence underpinning recommendations for increased therapy frequency and intensity. Units delivering more therapy had undertaken patient focused reorganisation of therapists' working practices, enabling them to provide therapy consistent with guideline recommendations. CONCLUSION: Time spent in information exchange impacted on therapy provision in stroke units. Reorganisation of therapists' work improved alignment with guidelines. PMID- 29582713 TI - A mixed treatment comparison on efficacy and safety of treatments for spasticity caused by multiple sclerosis: a systematic review and network meta-analysis. AB - OBJECTIVES: This study is aimed at providing a quantitative evaluation on different therapies of spasticity caused by multiple sclerosis. DATA SOURCES: PubMed and Embase database. REVIEW METHODS: We searched for randomized controlled trials that met the requirements. Percentages of improved patients' spasticity scale, mild adverse effect and severe adverse effect were extracted as outcomes. The forest plots accompanied with surface under the cumulative ranking curves were used to reveal the efficacy and safety of these therapies. RESULTS: In all, 23 randomized controlled trials with a total of 2720 patients were included in our study. Cannabinoids and botulinum toxin had shown a significantly better efficacy than placebo in the percentage of improved patients. Botulinum toxin also showed such significant difference compared with tizanidine and baclofen. No significant difference was found in spasticity scale. Cannabinoids, tizanidine and diazepam had significantly more mild adverse effect reports than placebo. Surface under the cumulative ranking curves suggested that cannabinoids, botulinum toxin and transcutaneous electric nerve stimulation were preferable therapies. CONCLUSIONS: We recommended botulinum toxin as the optimal intervention for multiple sclerosis-related spasticity. Cannabinoids and transcutaneous electric nerve stimulation could also be considered as multiple sclerosis-related spasticity treatments but their safety remained to be verified. PMID- 29582714 TI - The impact of Nordic walking training on the gait of the elderly. AB - The purpose of the current study was to define the impact of regular practice of Nordic walking on the gait of the elderly. Thereby, we aimed to determine whether the gait characteristics of active elderly persons practicing Nordic walking are more similar to healthy adults than that of the sedentary elderly. Comparison was made based on parameters computed from three inertial sensors during walking at a freely chosen velocity. Results showed differences in gait pattern in terms of the amplitude computed from acceleration and angular velocity at the lumbar region (root mean square), the distribution (Skewness) quantified from the vertical and Euclidean norm of the lumbar acceleration, the complexity (Sample Entropy) of the mediolateral component of lumbar angular velocity and the Euclidean norm of the shank acceleration and angular velocity, the regularity of the lower limbs, the spatiotemporal parameters and the variability (standard deviation) of stance and stride durations. These findings reveal that the pattern of active elderly differs significantly from sedentary elderly of the same age while similarity was observed between the active elderly and healthy adults. These results advance that regular physical activity such as Nordic walking may counteract the deterioration of gait quality that occurs with aging. PMID- 29582716 TI - Amygdala - and serum - neurotrophic factor levels depend on rearing condition in male rats. AB - Early life experiences could determine brain and behavioral development. Neurotrophic factors are likely to mediate the effects of the experience on brain structures and function. Brain-derived neurotrophic factor (BDNF) plays a central role in psychiatric disorders. To investigate the effects of early rearing condition on the amygdala - and serum - BDNF levels, we reared male Wistar rats from weaning (postnatal days 21) to adulthood (postnatal days 119) in three different rearing conditions: (1) enriched, (2) standard and (3) isolated. We found that long-term post-weaning environmental enrichment leads to lower amygdala - and serum - BDNF levels as well as lower brain weights. Grouped rearing in standard laboratory cages enhanced body weight. Thus, early rearing condition might play a crucial role in adult healthiness by predetermining individual BDNF profiles. PMID- 29582717 TI - Maternal protein malnutrition: effects on prostate development and adult disease. AB - Well-controlled intrauterine development is an essential condition for many aspects of normal adult physiology and health. This process is disrupted by poor maternal nutrition status during pregnancy. Indeed, physiological adaptations occur in the fetus to ensure nutrient supply to the most vital organs at the expense of the others, leading to irreversible consequences in tissue formation and differentiation. Evidence indicates that maternal undernutrition in early life promotes changes in key hormones, such as glucocorticoids, growth hormones, insulin-like growth factors, estrogens and androgens, during fetal development. These alterations can directly or indirectly affect hormone release, hormone receptor expression/distribution, cellular function or tissue organization, and impair tissue growth, differentiation and maturation to exert profound long-term effects on the offspring. Within the male reproductive system, maternal protein malnutrition alters development, structure, and function of the gonads, testes and prostate gland. Consequently, these changes impair the reproductive capacity of the male offspring. Further, permanent alterations in the prostate gland occur at the molecular and cellular level and thereby affect the onset of late life diseases such as prostatitis, hyperplasia and even prostate cancer. This review assembles current thoughts on the concepts and mechanisms behind the developmental origins of health and disease as they relate to protein malnutrition, and highlights the effects of maternal protein malnutrition on rat prostate development and homeostasis. Such insights on developmental trajectories of adult-onset prostate disease may help provide a foundation for future studies in this field. PMID- 29582715 TI - Intercellular mitochondria trafficking highlighting the dual role of mesenchymal stem cells as both sensors and rescuers of tissue injury. AB - Mitochondria are crucial organelles that not only regulate the energy metabolism, but also the survival and fate of eukaryotic cells. Mitochondria were recently discovered to be able to translocate from one cell to the other. This phenomenon was observed in vitro and in vivo, both in physiological and pathophysiological conditions including tissue injury and cancer. Mitochondria trafficking was found to exert prominent biological functions. In particular, several studies pointed out that this process governs some of the therapeutic effects of mesenchymal stem cells (MSCs). In this review, we give an overview of the current knowledge on MSC dependent intercellular mitochondria trafficking and further discuss the recent findings on the intercellular mitochondria transfer between differentiated and mesenchymal stem cells, their biological significance and the mechanisms underlying this process. PMID- 29582718 TI - Use of a Single Xpert MTB/RIF Assay to Determine the Duration of Airborne Isolation in Hospitalized Patients With Suspected Pulmonary Tuberculosis. AB - BACKGROUNDHospitalized patients with suspected tuberculosis (TB) are placed in airborne isolation until 3 sputum smear samples are negative for acid-fast bacilli (AFB). The Xpert MTB/RIF assay ("Xpert") nucleic acid amplification test (NAAT) to identify Mycobacterium tuberculosis DNA and resistance to rifampicin is superior to AFB sputum smear microscopy for the diagnosis of TB.OBJECTIVETo compare the performance of a single Xpert to AFB smear microscopy for time to airborne infection isolation (AII) discontinuation.METHODSConsecutive patients over 17 years of age in AII for suspected pulmonary TB between October 1, 2014, and March 31, 2016, with leftover respiratory AFB samples were enrolled in this study. A single Xpert was performed on the first available sample. Demographic, clinical, and microbiological data were recorded for each patient. We compared the duration of AII using a single Xpert to AFB smear microscopy under multiple theoretical scenarios using Kaplan-Meier cumulative incidence curves and the log rank test.RESULTSIn total, 131 samples were included in our performance analysis of the Xpert, and 114 samples were included in our AII analysis. Overall, 81 patients (65%) were immunosuppressed, of whom 46 (37%) were positive for human immunodeficiency virus (HIV). The sensitivity and specificity of Xpert for diagnosis of M. tuberculosis infection were 67% and 100%, respectively. Xpert was negative in all cases of nontuberculous mycobacteria. Use of a single Xpert reduced AII duration from a median of 67 hours per patient to 42 hours with usual reporting, to 26 hours with direct communication, and to 12 hours with immediate testing.CONCLUSIONSA single negative Xpert result can reduce AII duration compared to the AFB smear microscopy technique under multiple theoretical scenarios.Infect Control Hosp Epidemiol 2018;39:590-595. PMID- 29582719 TI - Urine Culture on Admission Impacts Antibiotic Use and Length of Stay: A Retrospective Cohort Study. AB - OBJECTIVETo examine the impact of urine culture testing on day 1 of admission on inpatient antibiotic use and hospital length of stay (LOS).DESIGNWe performed a retrospective cohort study using a national dataset from 2009 to 2014.SETTINGThe study used data from 230 hospitals in the United States.PARTICIPANTSAdmissions for adults 18 years and older were included in this study. Hospitalizations were matched with coarsened exact matching by facility, patient age, gender, Medicare severity-diagnosis related group (MS-DRG), and 3 measures of disease severity.METHODSA multilevel Poisson model and a multilevel linear regression model were used to determine the impact of an admission urine culture on inpatient antibiotic use and LOS.RESULTSMatching produced a cohort of 88,481 patients (n=41,070 with a culture on day 1, n=47,411 without a culture). A urine culture on admission led to an increase in days of inpatient antibiotic use (incidence rate ratio, 1.26; P<.001) and resulted in an additional 36,607 days of inpatient antibiotic treatment. Urine culture on admission resulted in a 2.1% increase in LOS (P=.004). The predicted difference in bed days of care between admissions with and without a urine culture resulted in 6,071 additional bed days of care. The impact of urine culture testing varied by admitting diagnosis.CONCLUSIONSPatients with a urine culture sent on day 1 of hospital admission receive more days of antibiotics and have a longer hospital stay than patients who do not have a urine culture. Targeted interventions may reduce the potential harms associated with low-yield urine cultures on day 1.Infect Control Hosp Epidemiol 2018;39:547-554.

AB - Hepatitis A infection results in a spectrum of illness from asymptomatic disease to severe fulminant hepatitis. Since 2000, <50 cases have been reported annually in Ireland. We report on an outbreak of hepatitis A associated with a childcare facility(CCF) in 2015 in Ireland. Between January and July 2015, 12 outbreak associated symptomatic hepatitis A cases were identified, including one delayed, retrospective diagnosis. Seven (58%) cases were adults, eight (67%) were male, six of the adults required hospitalisation. All 12 cases were confirmed on serology and the four cases that were genotyped were identical on phylogenetic analysis. Potential environmental exposures and hygiene practices at the CCF were investigated. Outbreak control measures included the provision of: hepatitis A information, infection prevention advice, hepatitis A vaccination to 554 CCF contacts, and voluntary closure of the CCF for deep-cleaning and staff education. From a healthcare perspective1, outbreak control costs were in excess of ?45 000. This outbreak illustrates the considerable adult morbidity that can occur in hepatitis A outbreaks, highlights the challenges in controlling a large CCF associated outbreak and the importance of early recognition by clinicians of hepatitis A. PMID- 29582722 TI - Intensity-Specific Differential Leukocyte DNA Methylation in Physical (In)Activity: An Exploratory Approach. AB - The aim of this exploratory study was to investigate how sedentary behavior (SB) and physical activity (PA) influence DNA methylation at a global, gene-specific, and health-related pathway level. SB, light PA (LPA), and moderate-to-vigorous PA (MVPA) were assessed objectively for 41 Flemish men using the SenseWear Pro 3 Armband. CpG site-specific methylation in leukocytes was determined using the Illumina HumanMethylation 450 BeadChip. Correlations were calculated between time spent on the three PA intensity levels and global DNA methylation, using a z score-based method to determine global DNA methylation levels. To determine whether CpG site-specific methylation can be predicted by these three PA intensity levels, linear regression analyses were performed. Based on the significantly associated CpG sites at alpha = 0.005, lists were created including all genes with a promoter region overlapping these CpG sites. A biological pathway analysis determined to what extent these genes are overrepresented within several pathways. No significant associations were observed between global DNA methylation and SB (r = 0.084), LPA (r = -0.168), or MVPA (r = -0.125), although the direction of the correlation coefficients is opposite to what is generally reported in literature. SB has a different impact on global and gene-specific methylation than PA, but also LPA and MVPA affect separate genes and pathways. Furthermore, the function of a pathway seems to determine its association with SB, LPA, or MVPA. Multiple PA intensity levels, including SB, should be taken into account in future studies investigating the effect of physical (in)activity on human health through epigenetic mechanisms. PMID- 29582723 TI - Are Migraine and Tension-Type Headache Genetically Related? An Investigation of Twin Family Data. AB - Migraine and tension-type headache (TTH) are often viewed as distinct entities and defined as such in the International Classification of Headache Disorders, 2nd edition (ICHD-II) criteria, although there is also empirical evidence to suggest they may be etiologically similar. This study aims to investigate whether migraine and TTH are etiologically related conditions. First, we explored whether migraine and TTH were associated with the same environmental and lifestyle risk factors at the population level. Second, we examined comorbidity of migraine and TTH in a twin design. By comparing the associations in monozygotic (MZ) and dizygotic (DZ) twin pairs, we investigated whether the comorbidity can be explained by genetic factors that influence both conditions. Results indicated that migraine and TTH were largely associated with the same environmental and lifestyle factors, including younger age, female sex, higher body mass index, more depression, stress at home, and less participation in regular exercise, with consistently stronger effects for migraine than for TTH. Migraine in one twin was significantly associated with TTH in the other twin. A stronger cross-trait, cross-twin association in MZ than DZ twins suggested that this comorbidity may also be partly due to shared genetic factors, although the difference in associations was not significant. In conclusion, our findings are consistent with the hypothesis that migraine and TTH have partly shared etiologies. For both treatment and research, it may be advisable not to make a rigid distinction, but to treat migraine and TTH as related conditions. PMID- 29582724 TI - Definitive Zygosity Scores in the Peas in the Pod Questionnaire is a Sensitive and Accurate Assessment of the Zygosity of Adult Twins. AB - Twin researchers face the challenge of accurately determining the zygosity of twins for research. As part of the annual questionnaire between 1999 and 2006, 8,307 twins from the TwinsUK registry were asked to complete five questions (independently from their co-twin) to ascertain their self-perceived zygosity during childhood on up to five separate occasions. This questionnaire is known as the 'peas in the pod' questionnaire (PPQ), but there is little evidence of its validation. Answers were scored and classified as monozygotic (MZ), dizygotic (DZ), or unknown zygosity (UZ) and were compared with 4,484 twins with genotyping data who had not been selected for zygosity. Of these, 3,859 individuals (46.5% of those who had a zygosity from PPQ) had zygosity classified by both the PPQ and genotyping. Of the 708 individual twins whose answers meant that they were consistently classed as MZ in the PPQ, 683 (96.5%) were MZ within the genotype data. Of the 945 individual twins consistently classed as DZ within questionnaire, 936 (99.0%) were DZ in the genotype data. Where both twins scored MZ consistently across multiple questionnaires, 99.6% were MZ on genotyping, 99.7% were DZ on genotyping if both twins consistently scored DZ. However, for the initial questionnaire, 88.6% of those scoring as MZ were genotypically MZ and 98.7% DZ. For twin pairs where both scored UZ, 94.7% were DZ. Using the PPQ on a single occasion provided a definitive classification of whether the twin was MZ or DZ with an overall accuracy of 86.9%, increasing to 97.9% when there was a consistent classification of zygosity across multiple questionnaires. This study has shown that the PPQ questionnaire is an excellent proxy indicator of zygosity in the absence of genotyping information. PMID- 29582727 TI - Maternal low-quality protein diet exerts sex-specific effects on plasma amino acid profile and alters hepatic expression of methyltransferases in adult rat offspring. AB - Nutrition during pregnancy and lactation is a critical factor in the development of the offspring. Both protein content and source in maternal diet affect neonatal health, but the long-term effects of maternal low-quality protein diet on the offspring are less clear. This study aimed to examine the effects of maternal low-quality protein diet on offspring's growth, development, circulating metabolites and hepatic expression of methyltransferases. Virgin Wistar rats were mated at 11 weeks of age. Dams were then maintained on either a chow diet with 20% casein as the control group (C), or a low-quality protein diet with 20% wheat gluten as the experimental group (WG) throughout gestation and lactation. After weaning, all offspring were fed a control chow diet until the age of 20 weeks. Male WG offspring had significantly lower body weight and energy intake, whereas female WG offspring had significantly higher body weight and energy intake when compared with controls. Early life exposure to WG diet had no significant effect on circulating metabolites. However, fasting insulin concentrations and homoeostasis model assessment-insulin resistance were decreased in WG male and female offspring. Maternal low-quality protein diet increased plasma aspartic acid, glutamic acid, histidine, cystathione and decreased lysine in male WG offspring. Conversely, the same amino acids were reduced in female WG offspring. Adult offspring exposed to WG diet had significantly upregulated hepatic DNMT3a and DNMT3b expressions. Our study showed that there were differential effects of maternal poor-quality protein diet upon adult offspring's metabolism. PMID- 29582728 TI - Polymorphisms in the K13 Gene in Plasmodium falciparum from Different Malaria Transmission Areas of Kenya. AB - The development of artemisinin (ART)-resistant parasites in Southeast Asia (SEA) threatens malaria control globally. Mutations in the Kelch 13 (K13)-propeller domain have been useful in identifying ART resistance in SEA. ART combination therapy (ACT) remains highly efficacious in the treatment of uncomplicated malaria in Sub-Saharan Africa (SSA). However, it is crucial that the efficacy of ACT is closely monitored. Toward this effort, this study profiled the prevalence of K13 nonsynonymous mutations in different malaria ecological zones of Kenya and in different time periods, before (pre) and after (post) the introduction of ACT as the first-line treatment of malaria. Nineteen nonsynonymous mutations were present in the pre-ACT samples (N = 64) compared with 22 in the post-ACT samples (N = 251). Eight of these mutations were present in both pre- and post-ACT parasites. Interestingly, seven of the shared single-nucleotide polymorphisms were at higher frequencies in the pre-ACT than the post-ACT parasites. The A578S mutation reported in SSA and the V568G mutation reported in SEA were found in both pre- and post-ACT parasites, with their frequencies declining post-ACT. D584Y and R539K mutations were found only in post-ACT parasites; changes in these codons have also been reported in SEA with different amino acids. The N585K mutation described for the first time in this study was present only in post-ACT parasites, and it was the most prevalent mutation at a frequency of 5.2%. This study showed the type, prevalence, and frequency of K13 mutations that varied based on the malaria ecological zones and also between the pre- and post-ACT time periods. PMID- 29582729 TI - Detection of Immunoglobulin G Antibodies to Taenia solium Cysticercosis Antigen Glutathione-S-Transferase-rT24H in Malian Children Using Multiplex Bead Assay. AB - Blood samples from 805 students attending 42 elementary schools in Mopti, Sikasso, and Koulikoro regions, and Bamako district in Mali participated in a school water, sanitation, and hygiene intervention. Immunoglobulin (Ig) G responses to several antigens/pathogens were assessed by a multiplex bead assay (MBA), and the recombinant Taenia solium T24H antigen was included. Of all students tested, 8.0% were positive to rT24H, but in some schools 25-30%. A cluster of 12 widespread school locations showed not only a relative risk of 3.23 for T. solium exposure and significantly higher IgG responses (P < 0.001) but also significantly lower elevation (P = 0.04) (m, above sea level) compared with schools outside the cluster. All schools at elevations < 425 m showed significantly higher IgG responses (P = 0.017) than schools at elevations >= 425 m. The MBA is an excellent serological platform that provides cost-effective opportunities to expand testing in serosurveys. PMID- 29582730 TI - Safe Water and Hygiene Integration with Human Immunodeficiency Virus and Antenatal Services: Leveraging Opportunities for Public Health Interventions and Improved Service Uptake. AB - Integrating public health interventions with antenatal clinic (ANC) visits may motivate women to attend ANC, thereby improving maternal and neonatal health, particularly for human immunodeficiency virus (HIV)-infected persons. In 2009, in an integrated ANC/Preventing Mother-to-Child Transmission program, we provided free hygiene kits (safe storage containers, WaterGuard water treatment solution, soap, and oral rehydration salts) to women at their first ANC visit and refills at subsequent visits. To increase fathers' participation, we required partners' presence for women to receive hygiene kits. We surveyed pregnant women at baseline and at 12-month follow-up to assess ANC service utilization, HIV counseling and testing (HCT), test drinking water for residual chlorine, and observe handwashing. We conducted in-depth interviews with pregnant women, partners, and health workers. We enrolled 106 participants; 97 (92%) were found at follow-up. During the program, 99% of pregnant women and their partners received HCT, and 99% mutually disclosed. Fifty-six percent of respondents had >= 4 ANC visits and 90% delivered at health facilities. From baseline to follow-up, the percentage of women who knew how to use WaterGuard (23% versus 80%, P < 0.0001), had residual chlorine in stored water (0% versus 73%, P < 0.0001), had confirmed WaterGuard use (0% versus 70%, P < 0.0003), and demonstrated proper handwashing technique (21% versus 64% P < 0.0001) increased. Program participants showed significant improvements in water treatment and hygiene, and high use of ANC services and HCT. This evaluation suggests that integration of hygiene kits, refills, and HIV testing during ANC is feasible and may help improve household hygiene and increase use of health services. PMID- 29582732 TI - Molecular Markers of Plasmodium falciparum Drug Resistance in Parasitemic Pregnant Women in the Middle Forest Belt of Ghana. AB - Data on prevalence of antimalarial molecular resistance markers in pregnant women in Ghana is scarce. Prevalence of single nucleotide polymorphisms/haplotypes in the Pfcrt, Pfmdr1, Pfdhfr, and Pfdhps genes was assessed in a cross-sectional study involving 200 pregnant women. Almost 90% of infections were wild type at the Pfcrt gene whereas the Pfmdr1 NFD mutant haplotype occurred in 43% of samples. Prevalence of Pfdhfr/Pfdhps quadruple mutation was 92.6% whereas Pfdfr/Pfdhps quintuple mutation with K540E was not observed. The study provides important updates of antimalarial resistance markers in Ghanaian pregnant women and suggests increased tolerance to one of the first-line treatment options in Ghana: artemether-lumefantrine. The data support the view that sulfadoxine pyrimethamine is still efficacious for intermittent preventive treatment in Ghana, but the impact of increased doses on selection of mutations needs to be assessed. Continuing the surveillance of resistance markers is important to inform changes in antimalarial drug policy in pregnancy. PMID- 29582731 TI - Vector-Borne Disease is a Common Cause of Hospitalized Febrile Illness in India. AB - Acute febrile illness (AFI) is a major cause of morbidity and mortality in India and other resource-limited settings, yet systematic etiologic characterization of AFI has been limited. We prospectively enrolled adults (N = 970) and children (age 6 months to 12 years, N = 755) admitted with fever from the community to Sassoon General Hospital in Pune, India, from July 2013 to December 2015. We systematically obtained a standardized clinical history, basic laboratory testing, and microbiologic diagnostics on enrolled participants. Results from additional testing ordered by treating clinicians were also recorded. A microbiological diagnosis was found in 549 (32%) participants; 211 (12%) met standardized case definitions for pneumonia and meningitis without an identified organism; 559 (32%) were assigned a clinical diagnosis in the absence of a confirmed diagnosis; and 406 (24%) had no diagnosis. Vector-borne diseases were the most common cause of AFI in adults including dengue (N = 188, 19%), malaria (N = 74, 8%), chikungunya (N = 15, 2%), and concurrent mosquito-borne infections (N = 23, 2%) occurring most frequently in the 3 months after the monsoon. In children, pneumonia was the most common cause of AFI (N = 214, 28%) and death. Bacteremia was found in 68 (4%) participants. Central nervous system infections occurred in 58 (6%) adults and 64 (8%) children. Etiology of AFI in India is diverse, highly seasonal, and difficult to differentiate on clinical grounds alone. Diagnostic strategies adapted for season and age may reduce diagnostic uncertainty and identify causative organisms in treatable, fatal causes of AFI. PMID- 29582733 TI - The Elderly Respond to Antimony Therapy for Cutaneous Leishmaniasis Similarly to Young Patients but Have Severe Adverse Reactions. AB - There is evidence that elderly patients with cutaneous leishmaniasis (CL) have more mucosal and disseminated diseases than young patients and their cells produce less antigen-induced interferon (IFN)-gamma. Herein, we compared the roles of interleukin (IL)-10 and IL-15 as modulators of antigen-induced immune responses and the incidence of adverse reaction and response to therapy in young versus elderly patients with CL. Study participants included 35 senior (60-85 years) and 35 young (18-40 years) patients who had a diagnosis of CL documented by typical cutaneous lesions containing Leishmania braziliensis DNA. Elderly patients had less lymph node enlargement. Antigen-induced blood cell cytokine responses were studied in the absence or presence of IL-10 antibody or exogenously added recombinant IL-15. The ratio of IFN-gamma/IL-10 was lower in elderly patients, and IFN-gamma production was enhanced by either neutralization of IL-10 or exogenous recombinant IL-15 in blood cells from elderly but not young patients. Patients were treated three times weekly with antimony at 20 mg/kg/day for 20 doses. Although there was no difference in response to therapy between the two groups, two young patients needed rescue therapy with amphotericin B. Ventricular arrhythmias and ventricular overload were more frequent in elderly patients. We conclude that elderly patients have alterations in the immune response that may influence clinical manifestations, but we did not find that they had a higher failure rate than young subjects to antimony therapy. However, because of the high rate of electrocardiographic abnormalities during therapy, antimony should not be used in elderly patients with CL. PMID- 29582734 TI - Knowledge of Norovirus and Attitudes toward a Potential Norovirus Vaccine in Rural Guatemala: A Cross-Sectional Exploratory Survey. AB - Given limited data on norovirus vaccine acceptance, we performed an exploratory survey in a rural Guatemalan community on knowledge, interest, and willingness to pay (WTP) for a norovirus vaccine. Cluster-randomized households with children aged 6 weeks to 17 years were enrolled into one of two norovirus surveillance studies: 1) a prospective cohort (N = 207 households) and 2) two separate, community-based, cross-sectional surveys (N = 420 households). After completion of the surveillance study, vaccine surveys were completed by 564 (90%) of 627 households. Most households correctly answered questions regarding norovirus symptoms and transmission; 97% indicated interest in a hypothetical norovirus vaccine. Households with higher education had greater WTP for a vaccine (prevalence ratios = 2.2, 95% confidence interval: 1.2-3.1) and households with lower WTP were more likely to use pharmacies, the Ministry of Health, and radios for health care and information. These results suggest that a future norovirus vaccination program could be acceptable and feasible even in rural areas. PMID- 29582735 TI - A Revival of Epidemiological Entomology in Senegal. PMID- 29582736 TI - Seroprevalence of Hepatitis A Virus, Hepatitis E Virus, and Helicobacter pylori in Rural Communities of the Bolivian Chaco, 2013. AB - In the Bolivian Chaco, south-east of Bolivia, studies conducted over the past three decades reported hepatitis A virus (HAV) and Helicobacter pylori seroprevalences above 90% and 60%, respectively. Hepatitis E virus (HEV) prevalence was previously found to be 6-7% but is probably an underestimate because of the poor sensitivity of the assays used. In November 2013, we conducted a cross-sectional study of 263 healthy volunteers from two rural communities of the Bolivian Chaco, aiming to reassess HAV, HEV, and H. pylori seroprevalence 10-20 years following the previous surveys. Hepatitis A virus seroprevalence was 95%, with universal exposure after the first decade of life; HEV seroprevalence was considerably higher (31-35%) than that previously reported; H. pylori seroprevalence was 59%, with an age-dependent distribution. The high prevalence of these infections suggests that major efforts are still needed to reduce fecal-oral transmission and to improve human health in the Bolivian Chaco. PMID- 29582737 TI - Case Report: Diffuse Cutaneous Leishmaniasis by Leishmania infantum in a Patient Undergoing Immunosuppressive Therapy: Risk Status in an Endemic Mediterranean Area. AB - This case report highlights the risk of severe cutaneous leishmaniasis (CL) by Leishmania infantum in patients undergoing immunosuppressant therapy who either live in an endemic area or are visiting in the transmission season. The case patient, resident in Majorca (Balearic Islands), presented 12 disseminated erythematous skin lesions, 1-6 cm in diameter, located on the scalp, cheek, umbilical region, and lower extremities 8 years after undergoing anti-tumor necrosis factor (TNF) therapy. Parasite presence in peripheral blood and high levels of specific antibodies were also observed, indicating a possible risk of CL shifting toward a visceral infection. However, once CL was diagnosed, anti-TNF therapy was discontinued and liposomal amphotericin B was administered, resulting in a complete healing of lesions, no Leishmania DNA detection in blood, and an important serological decrease in antibodies. The lack of data on the supposed epidemiological association between leishmaniasis and immunosuppressive therapy highlights the importance of implementing surveillance systems in endemic areas. No obvious relationship was found based on the data provided by the Balearic Islands Epidemiological System, in contrast with data reported in nearby endemic areas. This indicates that if the suspected association is to be clarified, greater efforts are needed to report information about concomitant diseases and therapies in leishmaniasis patients.

PMID- 29582740 TI - Physician extenders on surgical services: the need for a systems perspective. AB - SUMMARY: Adding physician extenders (PEs) to surgical teams has the potential to affect care delivery in multiple ways. To develop evidence-based recommendations on integrating PEs into surgical teams, we must recognize that patient care is a complex, adaptive system and requires a health systems perspective to understand how changes will affect outcomes. It is the best method of assessing the system adaptations and trade-offs of adding PEs prior to implementation. Such work would help to optimize research and management of limited health care resources. PMID- 29582741 TI - Idle hands? What we know about surgeon unemployment in Canada. AB - SUMMARY: The topic of unemployment and underemployment of Canadian general surgeons is being discussed more frequently despite relatively little evidence on the magnitude or impact of the problem. Using existing and new sources of health human resource data, a more accurate understanding of the situation can be attained. Although outright surgeon unemployment is rare, there is a population of dissatisfied new graduates who feel cornered into underemployment or locums. The number of practising general surgeons has outpaced population growth in recent years. However, the number of new trainees peaked in 2010 and has been decreasing steadily since then. There are many pressures that stand in the way of more accurate management of the general surgery workforce. A better understanding of the subject and better leadership at the national level may help improve system performance.

AB - SUMMARY: The rapid expansion of military medical service in the First World War, successfully completed under the direction of Surgeon General Guy Carleton Jones, remains an extraordinary achievement in Canada's history. In 1916, a conflict of personalities threatened confidence in the service. Eventually Prime Minister Sir Robert Borden's intervention restored the status quo, but the affair eclipsed Jones's outstanding career. PMID- 29582743 TI - Associations between provider and hospital volumes and postoperative mortality following total hip arthroplasty in New Brunswick: results from a provincial level cohort study. AB - BACKGROUND: Several international studies have reported negative associations between hospital and/or provider volume and risk of postoperative death following total hip arthroplasty (THA). The only Canadian studies to report on this have been based in Ontario and have found no such association. We describe associations between postoperative deaths following THA and provider caseload volume, also adjusted for hospital volume, in a population-based cohort in New Brunswick. METHODS: Our analyses are based on hospital discharge abstract data linked to vital statistics and to patient registry data. We considered all first known admissions for THA in New Brunswick between Jan. 1, 2007, and Dec. 31, 2013. Provider volume was defined as total THAs performed over the preceding 2 years. We fit logistic regression models to identify odds of dying within 30 and 90 days according to provider caseload volume adjusted for selected personal and contextual characteristics. RESULTS: About 7095 patients were admitted for THA in New Brunswick over the 7-year study period and 170 died within 30 days. We found no associations with provider volume and postoperative mortality in any of our models. Adjustment for contextual characteristics or hospital volume had no effects on this association. CONCLUSION: Our results suggest that patients admitted for hip replacements in New Brunswick can expect to have similar risk of death regardless of whether they are admitted to see a provider with high or low THA volumes and of whether they are admitted to the province's larger or smaller hospitals. PMID- 29582744 TI - Surgical intervention in pediatric trauma at a level 1 trauma hospital: a retrospective cohort study and report of cost data. AB - BACKGROUND: Given that the management of severely injured children requires coordinated care provided by multiple pediatric surgical subspecialties, we sought to describe the frequency and associated costs of surgical intervention among pediatric trauma patients admitted to a level 1 trauma centre in southwestern Ontario. METHODS: All pediatric (age < 18 yr) trauma patients treated at the Children's Hospital - London Health Sciences Centre (CH-LHSC) between 2002 and 2013 were included in this study. We compared patients undergoing surgical intervention with a nonsurgical group with respect to demographic characteristics and outcomes. Hospital-associated costs were calculated only for the surgical group. RESULTS: Of 784 injured children, 258 (33%) required surgery, 40% of whom underwent orthopedic interventions. These patients were older and more severely injured, and they had longer lengths of stay than their nonsurgical counterparts. There was no difference in mortality between the groups. Seventy-four surgical patients required intervention within 4 hours of admission; 45% of them required neurosurgical intervention. The median cost of hospitalization was $27 571 for the surgical group. CONCLUSION: One-third of pediatric trauma patients required surgical intervention, of whom one-third required intervention within 4 hours of arrival. Despite the associated costs, the surgical treatment of children was associated with comparable mortality to nonsurgical treatment of less severely injured patients. This study represents the most recent update to the per patient cost for surgically treated pediatric trauma patients in Ontario, Canada, and helps to highlight the multispecialty care needed for the management of injured children. PMID- 29582745 TI - Regional differences in aortic valve replacements: Atlantic Canadian experience. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is evolving rapidly and is increasingly being adopted in the treatment of aortic valve disease. The goal of this study was to examine regional differences in surgical aortic valve replacement (SAVR) and TAVI across Atlantic Canada. METHODS: We identified all patients who underwent SAVR or TAVI between Jan. 1, 2010, and Dec. 31, 2014, in New Brunswick, Nova Scotia and Newfoundland and Labrador. Data obtained included patient demographic characteristics and surgical procedure details. We performed univariate descriptive analyses and calculated crude and age- and sex-adjusted incidence rates. RESULTS: A total of 3042 patients underwent SAVR or TAVI during the study period, 1491 in Nova Scotia, 1042 in New Brunswick and 509 in Newfoundland and Labrador. Patient demographic characteristics were similar across regions. A much higher proportion of patients in Newfoundland and Labrador (43.6%) than in Nova Scotia (4.2%) or New Brunswick (13.6%) received a mechanical versus a bioprosthetic valve. Rates of TAVI increased over the study period, with New Brunswick adopting their program before Nova Scotia (144 v. 74 procedures). Adjusted rates of all AVR procedures remained stable in Nova Scotia (40-50 per 100 000 people). Adjusted rates were lower in New Brunswick and Newfoundland and Labrador than in Nova Scotia; they increased slowly in New Brunswick over the study period. CONCLUSION: Despite geographical proximity and similar patient demographic characteristics, there existed regional differences in the management of aortic valve disease within Atlantic Canada. Further study is required to determine whether the observed differences in age- and sex-adjusted rates of AVR may be explained by geographical disease-related differences, varying practice patterns or barriers in access to care. PMID- 29582746 TI - Intraoperative cell salvage with autologous transfusion in elective right or repeat hepatectomy: a propensity-score-matched case-control analysis. AB - BACKGROUND: Liver resection may be associated with substantial blood loss, and cell saver use has been recommended for patients at high risk. We performed a study to compare the allogenic erythrocyte transfusion rate after liver resection between patients who had intraoperative cell salvage with a cell saver device versus patients who did not. Our hypothesis was that cell salvage with autologous transfusion would reduce the allogenic blood transfusion rate. METHODS: Cell salvage was used selectively in patients at high risk for intraoperative blood loss based on preoperatively known predictors: right and repeat hepatectomy. Patients who underwent elective right or repeat hepatectomy between Nov. 9, 2007, and Jan. 27, 2016 were considered for the study. Data were retrieved from a liver resection database and were analyzed retrospectively. Patients with cell saver use (since January 2013) constituted the experimental group, and those without cell salvage (2007-2012), the control group. To reduce selection bias, we matched propensity scores. The primary outcome was the allogenic blood transfusion rate within 90 days postoperatively. Secondary outcomes were the number of transfused erythrocyte units, and rates of overall and infectious complications. RESULTS: Ninety-six patients were included in the study, 41 in the cell saver group and 55 in the control group. Of the 96, 64 (67%) could be matched, 32 in either group. The 2 groups were balanced for demographic and clinical variables. The allogenic blood transfusion rate was 28% (95% confidence interval [CI] 12.5%-43.7%) in the cell saver group versus 72% (95% CI 56.3%-87.5%) in the control group (p < 0.001). The overall and infectious complication rates were not significantly different between the 2 groups. CONCLUSION: Intraoperative cell salvage with autologous transfusion in elective right or repeat hepatectomy reduced the allogenic blood transfusion rate. PMID- 29582747 TI - Training surgical residents to use a framework to promote shared decision-making for patients with poor prognosis experiencing surgical emergencies. AB - BACKGROUND: Patients with poor underlying prognosis experiencing surgical emergencies face challenging treatment decisions. The Best Case/Worst Case (BC/WC) framework has improved shared decision-making by surgeons, but it is unclear whether residents can be similarly trained. We evaluated senior general surgical residents' acceptance of the BC/WC tool and their attitudes, confidence and actions before and after training. METHODS: Two-hour training included a didactic session, live demonstration, small-group practice and debriefing. We developed questionnaires to evaluate residents' attitudes, confidence and actions at 3 time points: before the intervention, after the intervention and 6 months after the intervention. We used the Ottawa Decision Support Framework Acceptability questionnaire to evaluate acceptability and a structured observation form to evaluate performance. RESULTS: Eighteen (50%) of 36 invited residents participated. Most residents (83%) felt that a new communication tool would be useful. Almost all (94%) used BC/WC in practice. Residents found the tool acceptable and useful to enhance preference-sensitive communications. They felt that the training was valuable and that role play was its greatest strength but that these situations were challenging to simulate. Barriers to BC/WC use included time constraints and difficulty defining the best and worst cases precisely. Summative attitudes and confidence scores were not different before and after the intervention; however, actions scores were higher after the intervention (p = 0.04). Residents performed a median of 15 (interquartile range 13-17) of the 19 elements on the formative performance evaluation. Commonly missed items were narrating outcomes of palliative approaches, prompting deliberation and providing treatment recommendations. CONCLUSION: Senior residents found the BC/WC tool to be acceptable and useful, and are amenable to training in this type of communication. After training, self-reported actions scores increased, and observed performance was accurate. PMID- 29582748 TI - Airway management changes associated with rising radiologic incidence of external laryngotracheal injury. AB - BACKGROUND: Traumatic laryngeal injuries are uncommon life-threatening injuries that require prompt, rational management of a potentially precarious airway. It is unclear whether the current incidence of laryngotracheal injury is due to enhanced injury detection or increased occurrence. The objective of this study was to evaluate the relations between diagnostic imaging with both initial airway management and surgical treatment in patients with external laryngotracheal injuries (ELTIs) in Alberta. METHODS: In this large-scale population-based analysis, we used regional health databases containing inpatient admissions, emergency department visits and trauma service activations employing International Classification of Diseases diagnostic codes to identify all ELTIs diagnosed from Apr. 1, 1995, to Dec. 31, 2011, in adults (age >= 16 yr). We evaluated health records and diagnostic imaging for injury features, airway management, operative interventions and hospital length of stay (LOS). RESULTS: Eighty-nine patients met the inclusion criteria. The incidence of ELTIs increased over time, paralleling a rise in detection during the period incorporating greater computed tomography (CT) use (p = 0.002). Endotracheal tube intubation was performed in 8/30 cases (27%) in the pre-CT era, compared to 38/59 cases (64%) in the post-CT era (p = 0.001); the use of surgical intervention remained consistent. The largest contributors to increased endotracheal tube placements were the emergency department and emergency medical services. No change in survival was detected, but mean LOS among patients admitted for minor, isolated ELTIs increased by 2.3 (95% confidence interval 0.14-4.8) days (p = 0.06), mostly for patients admitted under critical care for mechanical ventilation. CONCLUSION: Management of ELTIs shifted from predominantly conservative airway monitoring to endotracheal tube intubation over the study period in spite of no clinically significant change in injury severity or operative intervention frequency. The location of endotracheal tube placement suggests less comfort with ELTI among first-responder and emergency personnel. PMID- 29582750 TI - Kidney paired donation and the unique challenges of kidney shipment in Canada. AB - SUMMARY: Kidney paired donation (KPD) programs are an effort to bridge the disparity between kidney supply and demand. These programs combine several incompatible donor-recipient pairs in a national paired exchange database, thereby increasing the number of compatible matches. But KPD programs face unique challenges, particularly the large distances that often separate donors and recipients. Here we discuss key factors to consider when transitioning from a donor travelling model to a kidney shipment model in the Canadian context. PMID- 29582749 TI - Is radiofrequency ablation of varicose veins a valuable option? A systematic review of the literature with a cost analysis. AB - BACKGROUND: Since the 1990s, new techniques for the treatment of varicose veins have emerged, including radiofrequency ablation (RFA) and laser treatment. We performed a study to compare the safety, efficacy and outcomes of RFA compared to those of open surgery and laser ablation for the treatment of varicose veins. We also carried out a cost analysis of RFA compared to open surgery to assess whether RFA could help free up operating room time by being performed in an outpatient context. METHODS: We conducted a systematic literature review (publication date May 2010-September 2013 for articles in English, January 1991 September 2013 for those in French). We used several checklists to measure the quality of the studies. We also collected data on costing. RESULTS: The literature search identified 924 publications, of which 38 were retained for analysis: 15 literature reviews, 1 good-practice guideline and 22 new primary studies. The overall level of evidence was low to moderate owing to the limited sample sizes, lack of information on patient characteristics and lack of standardization of the outcome measures. However, the results obtained are consistent from study to study. In the short and medium term, RFA is considered as effective as open surgery or laser treatment (moderate level of evidence) and presents fewer major and minor complications than open surgery (low level of evidence). Radiofrequency ablation can be performed on an outpatient basis. We calculated that RFA would be about $110-$220 more expensive per patient than open surgery. CONCLUSION: Radiofrequency ablation is a valuable alternative to open surgery and would free up operating room time in a context of low accessibility.

AB - SUMMARY: Studies have shown that a number of women do not receive adjuvant radiation therapy following breast-conserving surgery; the reasons have not been well investigated. We reviewed the charts of 267 patients in our institution who did not receive radiation therapy following surgery in order to determine patient stated reasons for nonreceipt. We found that 43% of patients did not receive radiation because they received a completion mastectomy. Excluding these patients, reasons for nonreceipt of radiation therapy were sorted into 9 categories. Most patients declined radiation therapy (against physician advice). We identified 3 major barriers to receipt of radiation therapy: improper patient selection, transportation or ambulatory issues and patient fear surrounding radiation toxicity. All of these reasons are surmountable barriers to radiation receipt. PMID- 29582752 TI - Reduction of pancreatic anastomotic leakage after pancreaticoduodenectomy. PMID- 29582753 TI - The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea. AB - Giant viruses are ecologically important players in aquatic ecosystems that have challenged concepts of what constitutes a virus. Herein, we present the giant Bodo saltans virus (BsV), the first characterized representative of the most abundant group of giant viruses in ocean metagenomes, and the first isolate of a klosneuvirus, a subgroup of the Mimiviridae proposed from metagenomic data. BsV infects an ecologically important microzooplankton, the kinetoplastid Bodo saltans. Its 1.39 Mb genome encodes 1227 predicted ORFs, including a complex replication machinery. Yet, much of its translational apparatus has been lost, including all tRNAs. Essential genes are invaded by homing endonuclease-encoding self-splicing introns that may defend against competing viruses. Putative anti host factors show extensive gene duplication via a genomic accordion indicating an ongoing evolutionary arms race and highlighting the rapid evolution and genomic plasticity that has led to genome gigantism and the enigma that is giant viruses.

AB - When relatively sated, people (and rodents) are still easily tempted to consume calorie-dense foods, particularly those containing fat and sugar. Consumption of such foods while calorically replete likely contributes to obesity. The nucleus accumbens (NAc) opioid system has long been viewed as a critical substrate for this behavior, mainly via contributions to the neural control of consumption and palatability. Here, we test the hypothesis that endogenous NAc opioids also promote appetitive approach to calorie-dense food in states of relatively high satiety. We simultaneously recorded NAc neuronal firing and infused a u-opioid receptor antagonist into the NAc while rats performed a cued approach task in which appetitive and consummatory phases were well separated. The results reveal elements of a neural mechanism by which NAc opioids promote approach to high-fat food despite the lack of caloric need, demonstrating a potential means by which the brain is biased towards overconsumption of palatable food.

AB - Long-term depression (LTD) at parallel fiber (PF) to Purkinje cell (PC) synapses has been considered as a main cellular mechanism for motor learning. However, the necessity of LTD for motor learning was challenged by demonstration of normal motor learning in the LTD-defective animals. Here, we addressed possible involvement of LTD in motor learning by examining whether LTD occurs during motor learning in the wild-type mice. As a model of motor learning, adaptation of optokinetic response (OKR) was used. OKR is a type of reflex eye movement to suppress blur of visual image during animal motion. OKR shows adaptive change during continuous optokinetic stimulation, which is regulated by the cerebellar flocculus. After OKR adaptation, amplitudes of quantal excitatory postsynaptic currents at PF-PC synapses were decreased, and induction of LTD was suppressed in the flocculus. These results suggest that LTD occurs at PF-PC synapses during OKR adaptation. PMID- 29582757 TI - Pigs, pathogens, and public health.

AB - Low-dimensional piezoelectric nanostructures such as nanoparticles, nanotubes, nanowires, nanoribbons and nanosheets have been developed for potential applications as energy harvesters, tunable sensors, functional transducers and low-power actuators. In this study, lead-free BaTiO 3 nanorod bundle arrays (NBA) with highly piezoelectric properties were successfully synthesized on fluorine doped tin oxide (FTO) substrate via a two-step process consisting of TiO2 epitaxial growth and BaTiO3 conversion. Through the TiO2 epitaxial growth on FTO substrate, (001) oriented TiO2 nanostructures formed vertically-aligned NBA with a bundle diameter of 80 nm and an aspect ratio of six. In particular, chemical etching of the TiO2 NBA was conducted to enlarge the surface area for effective Ba2+ ion diffusion during the perovskite conversion process from TiO2 to BaTiO3. The final structure of perovskite BaTiO3 NBA was found to exhibit a feasible piezoelectric response of 3.56 nm with a clear phase change of 180 degrees from the single BaTiO3 bundle, by point piezoelectric forced microscopy (PFM) analysis. Consequently, highly piezoelectric NBA could be a promising nanostructure for various nanoscale electronic devices.

AB - Top-gated and bottom-gated transistors with multilayer MoS2 channel fully encapsulated by stacked Al2O3/HfO2 (9 nm/6 nm) were fabricated and comparatively studied. Excellent electrical properties are demonstrated for the TG transistors with high on-off current ratio of 108, high field-effect mobility of 102 cm2 V-1 s-1, and low subthreshold swing of 93 mV dec-1. Also, enhanced reliability has been achieved for the TG transistors with threshold voltage shift of 10-3-10-2 V MV-1 cm-1 after 6 MV cm-1 gate-biased stressing. All improvement for the TG device can be ascribed to the formed device structure and dielectric environment. Degradation of the performance for the BG transistors should be attributed to reduced gate capacitance density and deteriorated interface properties related to vdW gap with a thickness about 0.4 nm. So, the TG transistor with MoS2 channel fully encapsulated by stacked Al2O3/HfO2 is a promising way to fabricate high performance ML MoS2 field-effect transistors for practical electron device applications. PMID- 29582777 TI - A simple bipedal model for studying control of gait termination. AB - We study the control of human gait termination with a simple bipedal locomotion model. Several control strategies have been proposed for gait termination. However, the relative importance of these strategies has not been evaluated in models of human gait. Here we extend the bipedal spring mass walking model in a least parameter fashion and study three explicit control strategies for gait termination, including the shortening of the final step, braking at the ankle, and extending the knee. Applying the strategies separately, we find that only braking at the ankle reduces the propulsive force enough to transition into quiet standing. In combination with the other two strategies, we observe that the range of control parameters suitable for gait termination increases, especially when the ankle control is applied intermittently by taking advantage of passive stabilizing dynamics. We further show the resulting model behavior is compatible with several experimental observations about the human center of mass dynamics and leg forces during gait termination, and discuss model improvements to correct mismatches. The proposed model may serve as a starting point for more advanced models that can provide a deeper understanding of human control strategies during gait termination.

AB - Mesoporous nickel oxides (NiO) and stannum(Sn)-doped NiO nanowires (NWs) were synthesized by using SBA-15 templates with the nanocasting method. X-ray diffraction, transmission electron microscope, energy dispersive spectrometry, nitrogen adsorption/desorption isotherm and UV-vis spectrum were used to characterize the phase structure, components and microstructure of the as prepared samples. The gas-sensing analysis indicated that the Sn-doping could greatly improve the ethanol sensitivity for mesoporous NiO NWs. With the increasing Sn content, the ethanol sensitivity increased from 2.16 for NiO NWs up to the maximum of 15.60 for Ni0.962Sn0.038O1.038, and then decreased to 12.24 for Ni0.946Sn0.054O1.054 to 100 ppm ethanol gas at 340 degrees C. The high surface area from the Sn-doping improved the adsorption of oxygen on the surface of NiO NWs, resulting in the smaller surface resistance in air. Furthermore, owing to the recombination of the holes in hole-accumulation lay with the electrons from the donor impurity level and the increasing the body defects for Sn-doping, the total resistance in ethanol gas enhanced greatly. It was concluded that the sensitivity of Sn-doped NiO NWs based sensor could be greatly improved by the higher surface area and high-valence donor substitution from Sn-doping. PMID- 29582779 TI - Immobilized Pd-Ag bimetallic nanoparticles on polymeric nanofibers as an effective catalyst: effective loading of Ag with bimetallic functionality through Pd nucleated nanofibers. AB - Here, we present a precise process for synthesizing Pd-Ag bimetallic nanoparticles (NPs) onto polymeric nanofibers by decorating Pd-NPs through atomic layer deposition followed by a chemical reduction process for tagging Ag nanostructures with bimetallic functionality. The results show that Pd-NPs act as a nucleation platform for tagging Ag and form Pd-Ag bimetallic NPs with a monodisperse nature with significant catalytic enhancement to the reaction rate over the bimetallic nature of the Pd-Ag ratio. A Pd-NP decorated polymeric nanofibrous web acts as an excellent platform for the encapsulation or interaction of Ag, which prevents agglomeration and promotes the interaction of Ag ions only on the surface of the Pd-NPs. We observed an effective reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by sodium borohydride (NaBH4) to access the catalytic activity of Pd-Ag bimetallic NPs on a free-standing flexible polymeric nanofibrous web as a support. The captive formation of the polymeric nanofibrous web with Pd-Ag bimetallic functionality exhibited superior and stable catalytic performance with reduction rates of 0.0719, 0.1520, and 0.0871 min-1 for different loadings of Ag on Pd decorated nanofibrous webs such as Pd/Ag(0.01), Pd/Ag(0.03), and Pd/Ag(0.05), respectively. The highly faceted Pd-Ag NPs with an immobilized nature improves the catalytic functionality by enhancing the binding energy of the 4-NP adsorbate to the surface of the NPs. With the aid of bimetallic functionality, the nanofibrous web was demonstrated as a hybrid heterogeneous photocatalyst with a 3.16-fold enhancement in the reaction rate as compared with the monometallic decorative nature of NaBH4 as a reducing agent. The effective role of the monodisperse nature of Pd ions with an ultralow content as low as 3 wt% and the tunable ratio of Ag on the nanofibrous web induced effective catalytic activity over multiple cycles. PMID- 29582780 TI - MR-compatibility assessment of MADPET4: a study of interferences between an SiPM based PET insert and a 7 T MRI system. AB - Compromises in the design of a positron emission tomography (PET) insert for a magnetic resonance imaging (MRI) system should minimize the deterioration of image quality in both modalities, particularly when simultaneous demanding acquisitions are performed. In this work, the advantages of using individually read-out crystals with high-gain silicon photomultipliers (SiPMs) were studied with a small animal PET insert for a 7 T MRI system, in which the SiPM charge was transferred to outside the MRI scanner using coaxial cables. The interferences between the two systems were studied with three radio-frequency (RF) coil configurations. The effects of PET on the static magnetic field, flip angle distribution, RF noise, and image quality of various MRI sequences (gradient echo, spin echo, and echo planar imaging (EPI) at 1H frequency, and chemical shift imaging at 13C frequency) were investigated. The effects of fast-switching gradient fields and RF pulses on PET count rate were studied, while the PET insert and the readout electronics were not shielded. Operating the insert inside a 1H volume coil, used for RF transmission and reception, limited the MRI to T1 weighted imaging, due to coil detuning and RF attenuation, and resulted in significant PET count loss. Using a surface receive coil allowed all tested MR sequences to be used with the insert, with 45-59% signal-to-noise ratio (SNR) degradation, compared to without PET. With a 1H/13C volume coil inside the insert and shielded by a copper tube, the SNR degradation was limited to 23-30% with all tested sequences. The insert did not introduce any discernible distortions into images of two tested EPI sequences. Use of truncated sinc shaped RF excitation pulses and gradient field switching had negligible effects on PET count rate. However, PET count rate was substantially affected by high-power RF block pulses and temperature variations due to high gradient duty cycles. PMID- 29582781 TI - Objective profiling of varied human motion based on normative assessment of magnetometer time series data. AB - OBJECTIVE: To quantify varied human motion and obtain an objective assessment of relative performance across a cohort. APPROACH: A wrist-worn magnetometer was used to record and quantify the complex motion patterns of 55 children aged 10 to 12 years old, generated during a fundamental movement skills programme. Sensor based quantification of the physical activity used dynamic time warping of the magnetometer time series data for pairs of children. Pairwise comparison across the whole cohort produced a similarity matrix of all child to child correlations. Normative assessment scores were based on the Euclidean distance between n participants within an n - 1 multi-variate space, created from multi dimensional scaling of the similarity matrix. The sensor-based scores were compared to the current standardised assessment which involves binary scoring of technique, outcome and time components by trained assessors. MAIN RESULTS: Visualisation of the relative performance using the first three axes of the multi dimensional matrix, shows a 'performance sphere' in which children sit on concentric shells of increasing radius as performance deteriorates. Good agreement between standard and sensor scores is found, with Spearman rank correlation coefficients of the overall activity score in the range of 0.62-0.71 for different cohorts and a kappa statistic of 0.34 for categorisation of all 55 children into lower, middle, upper tertile and top 5% bands. SIGNIFICANCE: By using multi-dimensional analysis of similarity measures between participants rather than direct parameterisation of the physiological data, complex and varied patterns of physical motion can be quantified, allowing objective and robust profiling of relative function across participant groups.

PMID- 29582783 TI - Modulation of the photoluminescence in carbon dots through surface modification: from mechanism to white light-emitting diodes. AB - Carbon dots (CDs) have emerged as a new type of fluorescent material because of their unique optical advantages, such as high photoluminescence quantum yields (QYs), excellent photo-stability, excitation-dependent emissions, and low toxicity. However, the photoluminescence mechanism for CDs remains unclear, which limits their further practical application. Here, CDs were synthesized via a solvothermal route from citric acid and urea. Through the oxidation and reduction treatment of pristine CDs, the origin of the photoluminescence and the involved mechanism were revealed. We found that the blue/green/red emissions originated from three diverse emitting states, i.e. the intrinsic state, and C=O- and C=N related surface states, respectively. Based on the as-prepared CDs, a pH sensor depending on the radiometric luminescence detection was developed. Furthermore, we constructed CD/PVP (PVP, polyvinylpyrrolidone) composite films, which exhibited white light emission with photoluminescence QYs of 15.3%. The white light emission with different correlated color temperatures (CCTs), from 4807 K to 3319 K, was obtained by simply changing the amount of PVP solution. Benefiting from the white light-emitting solid-state films, single-component white light emitting diodes were fabricated with an average color rendering index value (Ra) of 80.0, luminous efficiency of 10.2 lm W-1, and good working stability, thus indicating a promising potential for practical lighting applications.

AB - Metal-phosphorus-trichalcogenides (MPTs), represented by NiPS3, FePS3, etc, are newly developed 2D wide-bandgap semiconductors and have been proposed as excellent candidates for ultraviolet (UV) optoelectronics. In spite of having superior advantages for solar-blind UV photodetectors, including those free of surface trap states, being highly compatible with versatile integrations as well as having an appropriate band gap, to date relevant study is rare. In this work, the photoresponse characteristic of UV detectors based on few-layer FePS3 has been comprehensively investigated. The responsivity of the photodetector, which is observed to be determined by bias gate voltage, may achieve as high as 171.6 mAW-1 under the illumination of 254 nm weak light, which is comparable to most commercial UV detectors. Notably, both negative and positive photoconductivities exist in the FePS3 photodetectors and can be controllably switched with bias voltage. The eminent and novel photoresponse property paves the way for the further development and practical use of 2D MPTs in high-performance UV photodetections. PMID- 29582786 TI - Surface wave energy absorption by a partially submerged bio-inspired canopy. AB - Aquatic plants are known to protect coastlines and riverbeds from erosion by damping waves and fluid flow. These flexible structures absorb the fluid-borne energy of an incoming fluid by deforming mechanically. In this paper we focus on the mechanisms involved in these fluid-elasticity interactions, as an efficient energy harvesting system, using an experimental canopy model in a wave tank. We study an array of partially-submerged flexible structures that are subjected to the action of a surface wave field, investigating in particular the role of spacing between the elements of the array on the ability of our system to absorb energy from the flow. The energy absorption potential of the canopy model is examined using global wave height measurements for the wave field and local measurements of the elastic energy based on the kinematics of each element of the canopy. We study different canopy arrays and show in particular that flexibility improves wave damping by around 40%, for which half is potentially harvestable. PMID- 29582785 TI - Impact of anti-charge sharing on the zero-frequency detective quantum efficiency of CdTe-based photon counting detector system: cascaded systems analysis and experimental validation. AB - Inter-pixel communication and anti-charge sharing (ACS) technologies have been introduced to photon counting detector (PCD) systems to address the undesirable charge sharing problem. In addition to improving the energy resolution of PCD, ACS may also influence other aspects of PCD performance such as detector multiplicity (i.e. the number of pixels triggered by each interacted photon) and detective quantum efficiency (DQE). In this work, a theoretical model was developed to address how ACS impacts the multiplicity and zero-frequency DQE [DQE(0)] of PCD systems. The work focused on cadmium telluride (CdTe)-based PCD that often involves the generation and transport of K-fluorescence photons. Under the parallel cascaded systems analysis framework, the theory takes both photoelectric and scattering effects into account, and it also considers both the reabsorption and escape of photons. In a new theoretical treatment of ACS, it was considered as a modified version of the conventional single pixel (i.e. non-ACS) mode, but with reduced charge spreading distance and K-fluorescence travel distance. The proposed theoretical model does not require prior knowledge of the detailed ACS implementation method for each specific PCD, and its parameters can be experimentally determined using a radioisotope without invoking any Monte Carlo simulation. After determining the model parameters, independent validation experiments were performed using a diagnostic x-ray tube and four different polychromatic beams (from 50 to 120 kVp). Both the theoretical and experimental results demonstrate that ACS increased the first and second moments of multiplicity for a majority of the x-ray energy and threshold levels tested, except when the threshold level was much lower than the x-ray energy level. However, ACS always improved DQE(0) at all energy and threshold levels tested. PMID- 29582787 TI - Association between human leukocyte antigen-DRB1 and human leukocyte antigen-DQB1 alleles and pemphigus vulgaris in Indian patients: A case-control study. AB - Background: HLA-DRB1*04, -DRB1*08, -DRB1*14, -DQB1*03 and -DQB1*05 are reported to have significant association with pemphigus vulgaris; however, this is partially dependent on ethnicity. This study was done to determine the HLA-DR and -DQ types prevalent in Indian patients with pemphigus vulgaris. Methods: A prospective case-control study was done for a period of 9 months in Christian Medical College Vellore, India. HLA typing was done by PCR-SSOP method in 50 cases and 50 healthy controls. Allele frequencies in cases and controls were compared and odds ratios with 95% confidence interval were calculated. Results: The mean age of the patients (29 females, 21 males) and that of controls (36 males, 14 females) were 41.3 +/- 13.65 and 35.42 +/- 11.09 years, respectively. HLA-DRB1*14 was present in 47 patients and 18 controls (OR, 27.85; 95% CI, 7.57 102.42) and HLA-DQB1*05 was seen in 47 patients and 24 controls (OR, 16.97; 95% CI, 4.66-61.80). The haplotype DRB1*14, DQB1*05 was present in 44 patients and 14 controls (OR, 18.86; 95% CI, 6.58-54.05). DRB1*15 was present in 7 cases and 16 controls (OR, 0.35; 95% CI, 0.13-0.94) and DQB1*06 was present in 8 cases and 19 controls (OR, 0.31; 95% CI, 0.12-0.80). HLA-DQB1*03 was associated with significantly higher pemphigus disease area index scores. Limitations: The main limitations were that the numbers studied were small as the study was conducted at a single center, and the haplotype analysis was limited only to the proband. PDAI scores could have been influenced by prior treatment. Conclusion: There was a significant association between HLA-DRB1*14 and HLA-DQB1*05 and pemphigus vulgaris in our patients. A negative association was seen with DRB1*15 and DQB1*06. PMID- 29582788 TI - Solitary nodular lesion on forehead in a 56-year-old woman. PMID- 29582789 TI - Serum and tissue angiotensin-converting enzyme in patients with alopecia areata. AB - BACKGROUND: Alopecia areata is an immune-dependent disorder characterized by the interaction of T-lymphocytes with follicular antigens. Recent studies have shown the existence of a local renin-angiotensin system in the skin, where angiotensin converting enzyme (ACE) plays a role in autoimmunity and inflammation. AIM: The objective of this study was to evaluate serum and tissue ACE activity in patients with alopecia areata. METHODS: This case-control study was conducted on patients with alopecia areata and healthy controls. Serum and tissue ACE activity were assessed and compared between the two groups. RESULTS: Twenty-five alopecia areata patients (60% male, mean age 32.1 +/- 9.9 years) and 24 controls (50% male, mean age 37.4 +/- 8.8 years) were included. Mean serum ACE activity was 52.1 +/- 9 U/L in cases and 55.3 +/- 14.7 U/L in controls (P = 0.37). Tissue ACE activity was significantly lower in cases in all parts of the skin i.e. epidermis (P = 0.016), follicular epithelium (P = 0.004), and endothelium (P = 0.037). Among cases, serum ACE activity was significantly higher in patients with more severe disease (P = 0.030), nonpatchy alopecia areata (alopecia universalis; ophiasis, patchy and ophiasis, diffuse) (P = 0.029), and with nail involvement (P = 0.027). LIMITATIONS: The sample size was too small to draw definite conclusions. Further, most of the patients had only mild or moderate alopecia areata. CONCLUSION: Unlike in some other inflammatory diseases, the tissue level of ACE seems to be significantly lower in alopecia areata compared to normal controls. Serum ACE was significantly higher in patients with more severe disease. PMID- 29582790 TI - Papillary eccrine adenoma associated with syringocystadenoma papilliferum.

AB - Despite impressive survival benefits with immunotherapy in patients with various solid tumors, the full potential of these agents in prostate cancer has yet to be realized. Sipuleucel-T demonstrated a survival benefit in this population, indicating that prostate cancer is an immunoresponsive disease; however, these results have not been matched by other agents. A large trial with ipilimumab in prostate cancer failed to meet its primary objective, and small trials with PD 1/PD-L1 inhibitors did not yield a significant improvement in overall response. However, several late-stage clinical trials are underway with other vaccines in prostate cancer. Reports of clinical benefit with immunotherapies, particularly when used in combination or a select population, have provided the framework to develop sound clinical trials. Understanding immunogenic modulation, antigen spread, biomarkers, and DNA-repair defects will also help mold future strategies. Through rational patient selection and evidence-based combination approaches, patients with prostate cancer may soon derive durable survival benefits with immunotherapies.

AB - Introduction: Laparoscopic ventral mesh rectopexy (LVMR) has gained widespread acceptance for the management of complete rectal prolapse (CRP). However, there have been concerns considering its use in patients with a redundant sigmoid colon. This study was conducted to evaluate the anatomical and functional results following LVMR, particularly in cases of CRP with a redundant sigmoid colon. Materials and Methods: Retrospective analysis of 25 patients who underwent LVMR from January 2011 to September 2016 was performed. Patients were divided into two groups according to the duration of follow-up. Group A (long-term) with follow-up >3 years and Group B (mid-term) <3 years. Results: The study included 25 patients (M:F = 1.5:1) with a median age of 38 years. Eighty-eight percent of the patients had a redundant sigmoid colon. Significant improvement in post-operative Wexner score as compared to pre-operative values was seen in patients with pre-existing constipation (P < 0.0001). In patients presenting with faecal incontinence (FI), significant improvement in post-operative St. Mark's incontinence score was observed. Functional outcomes remain consistent in long-term follow-up (>3 years). Conclusions: LVMR seems to be a feasible surgical procedure with minimum morbidity and good long-term functional outcomes. It provides satisfactory results in patients with redundant sigmoid colon and improves pre-existing constipation and FI.

AB - INTRODUCTION: Robotic-assisted total mesorectal excision (TME) with pelvic intraoperative neuromapping was recently accomplished. However, neuromapping is conventionally conducted by a hand-guided laparoscopic probe. We introduce a prototype microfork probe to make robotic-guided neuromapping feasible. Experiments and Technical Setup: Two porcine experiments with nerve-sparing TME surgery were performed. A newly designed prototype bipolar microfork probe was inserted intraabdominally and guided with the robotic forceps. Intermittent neuromapping was then conducted and neuromonitoring data integrated in the surgeon console viewer. CONCLUSION: Robotic-guided neuromapping is shown to be feasible and fully controllable from the surgeon console.

AB - Aims: To analyse the feasibility of laparoscopic radical nephrectomy (LRN) for renal tumours >7 cm and to compare the operative and oncologic outcomes with open radical nephrectomy (ORN). Settings and Design: This was a prospective, observational, comparative study. Subjects and Methods: The study was conducted at a tertiary care super-speciality hospital. All the patients who underwent radical nephrectomy for >7 cm renal tumours during a period of 2 years (April 2012 to May 2014) were included in the study. Thirty patients were included in each ORN and LRN group. Pre-operative, intra-operative and post-operative data for all these patients were collected and analysed. Statistical Analysis Used: Statistical Package for the Social Sciences (SPSS, version 11.0 for Windows, Chicago, IL). Results: Mean age of patients in ORN and LRN groups was 57.3 +/- 6.1 years and 54.9 +/- 5.7 years, respectively (P = 0.220). As compared to ORN, LRN had less drop in post-operative haemoglobin (1.39 +/- 0.55 g/dl vs. 4.07 +/- 1.023 g/dl, P < 0.05), less drop in haematocrit value (4.7 +/- 3.25% vs. 9.5 +/- 5.13%, P < 0.05), less analgesic requirement for tramadol hydrochloride (165 +/- 74.5 mg vs. 260 +/- 181.66 mg) and less mean hospital stay (4.2 days vs. 6.1 days, P < 0.05). There was no statistically significant difference in post operative complication rate and recurrence-free survival over a median follow-up of 17 months (93.9% - LRN vs. 90% - ORN). Conclusions: LRN for large renal tumours is feasible and achieves oncologic outcomes similar to that obtained with ORN. PMID- 29582795 TI - Laparoscopic Nissen fundoplication: The effects of high-concentration supplemental perioperative oxygen on the inflammatory and immune response: A randomised controlled trial. AB - Background: A number of studies have been reported on the effects of high concentration oxygen (HCO) on cytokine synthesis, with controversial results. We assessed the effect of administration of perioperative HCO on systemic inflammatory and immune response in patients undergoing laparoscopic Nissen fundoplication (LNF). Materials and Methods: Patients (n = 117) were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 58) or 80% (n = 59). Administration was commenced after induction of anaesthesia and maintained for 6 h after surgery. White blood cells, peripheral lymphocytes subpopulation, human leucocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin (IL)-1 and IL-6 and C-reactive protein (CRP) were investigated. Results: A significantly higher concentration of neutrophil elastase, IL-1, IL-6 and CRP was detected post-operatively in the 30% FiO2group patients in comparison with the 80% FiO2group (P < 0.05). A statistically significant change in HLA-DR expression was recorded post-operatively at 24 h, as a reduction of this antigen expressed on monocyte surface in patients from 30% FiO2group; no changes were noted in 80% FiO2group (P < 0.05). Conclusions: This study demonstrated that perioperative HCO (80%), during LNF, can lead to a reduction in post-operative inflammatory response, and possibly, avoid post operative immunosuppression.

AB - Bleeding in a minimal access surgery can be very intimidating for a laparoscopic surgeon. Open conversion becomes an imminent option in these situations. Although open conversion is not a surgical defeat, in certain situations, bleeding can be salvaged using a 'rescue stitch.' We, herein, describe rescue stitch along with a rescue tray and its application during intraoperative bleeding in minimal access surgery. PMID- 29582798 TI - Our experience of laparoscopic pyloromyotomy with ultrasound-guided parameters. AB - Traditional management of infantile Hypertrophic Pyloric Stenosis is open pyloromyotomy after initial adequate resuscitation of the patient. From 1991, laparoscopic approach is considered feasible and safe. Today, diagnosis of hypertrophic pyloric stenosis is made most often made by ultrasound. With use of ultrasound-guided parameters (length of pyloric tumour and thickness of pyloric tumour), we could avoid 'incomplete pyloromyotomy' and 'mucosal perforation' (most common complications in laparoscopic approach) to achieve 100% adequacy and safety in laparoscopic pyloromyotomy. PMID- 29582799 TI - Laparoscopic hysterectomy for large uteri: Outcomes and techniques. AB - Aim: The aim of this study was to analyse our data of laparoscopic hysterectomy for large uteri (>16 weeks size) regarding their perioperative outcomes and possible factors for conversions to open surgery over 5 years. It also describes our techniques for the feasibility of performing such hysterectomies by the minimally invasive way. Materials and Methods: A five-year retrospective chart review was performed at the Minimal Access and Robotic Surgery Unit of the Department of Gynecology at Apollo Hospital, Hyderabad. Demographic and pre operative and post-operative data were recorded. Clinical assessment including bimanual examination and surgery was made by a single senior surgeon. Intra operative conversions, complications and post-operative complications were recorded. Results: A total of 128 women were included in this study, 5 patients underwent robotic-assisted hysterectomy. The average age was 44.4, body mass index - was 27.6 and size of the uterus was 17.5 weeks. The most common diagnosis was leiomyoma. The median Operating room (OR) time was 107 min. There was a need for myomectomy in 39.8%, extensive adhesiolysis in 33.6% and dense bladder adhesion in 26.6%. The average drop in haemoglobin was 1.72 g%, and hospital stay was 2 days. The specimen was removed by vaginal morcellation (2 cases via an umbilical port). Conversion to open surgery was required in 10.9% of cases. The conversion was significantly correlated with excessive haemorrhage and bladder injury but not with difficult hysterectomy, difficult bladder dissection or adhesions. There were 3 cases of bladder injury detected and managed intraoperatively. Conclusion: Laparoscopic hysterectomy is technically feasible and safe procedure for large uteri. The learning curve is about 50 cases and can be performed by experienced surgeons regardless of the size, number or location of the myomas without much morbidity. PMID- 29582800 TI - Laparoscopic retromuscular incisional hernia repair. AB - A 67-year-old male with a history of a conventional right colectomy and hypertension was referred to our department for an incisional hernia and abdominal discomfort. Physical examination also showed a supraumbilical defect that was confirmed with a computed tomography scan. Laparoscopic Rives technique repair was done to repair the defect avoiding direct contact of the mesh with the intra-abdominal viscera. PMID- 29582801 TI - Short-term outcomes of minimally invasive surgery for patients presenting with suspected gallbladder cancer: Report of 8 cases. AB - INTRODUCTION: Minimally invasive surgery (MIS) for gallbladder cancer (GBCa) has traditionally been discouraged, with limited studies reporting on its outcomes. The aim of this study was to evaluate the short-term outcomes of MIS for patients with GBCa or suspected GBCa. METHODS: A retrospective study of 8 consecutive patients who underwent MIS for GBCa by a single surgeon over a 22-month period between 2015 and 2017. RESULTS: Three patients underwent robotic surgery, while five underwent conventional laparoscopic surgery. Four patients presented with histologically proven GbCa detected incidentally after cholecystectomy. All 4 patients underwent resection of Segment 4b/5. Of these, 3 underwent hilar lymphadenectomy and 1 underwent hilar lymph node sampling. Four patients presenting with suspected GBCa underwent upfront extended cholecystectomy. Two patients who had malignancy on frozen section underwent hilar lymphadenectomy. The median operation time was 242.5 (range, 165-530) min, and the median blood loss was 175 (range, 50-700) ml. The median post-operative hospital stay was 3.5 (range, 2-8) days. There were no open conversion, post-operative morbidities and mortalities. Six had histologically proven GBCa. Five were T3 and one had T2 cancers. CONCLUSIONS: The results of the present study confirm the short-term safety and feasibility of MIS for patients with GBCa, as all eight patients underwent successful MIS with no major morbidity or mortality. Further studies with larger patient cohorts with long-term follow-up are needed to determine the oncologic outcomes and the definitive role of MIS in treating GBCa. PMID- 29582802 TI - The surgical outcome of minimally invasive pharyngo-laryngo-oesophagectomy in prone position. AB - PURPOSE: Pharyngo-laryngo-oesophagectomy (PLE) which is mainly indicated for cervical oesophageal cancer or synchronous double cancer of the thoracic oesophagus and the pharynx or larynx, is extremely invasive. Since minimally invasive oesophagectomy (MIE) using video-assisted thoracic surgery has become popular recently, the procedure can be adopted to PLE. Moreover, the use of the prone position (PP) in MIEs has been increasing recently because technical advantages and fewer post-operative complications were reported. To assess the validity of PP, this study compared surgical outcomes of minimally invasive PLE (MIPLE) in PP with that in the left lateral decubitus position (LLDP). PATIENTS AND METHODS: This study enrolled consecutive 15 patients that underwent MIPLE with LLDP (n = 7) or PP (n = 8) between January 1996 and October 2016. The patients' background characteristics, operative findings and post-operative complications were examined. RESULTS: Eligible diseases are 5 cases of cervical oesophageal cancer, 9 cases of synchronous double cancer of the thoracic oesophagus and head and neck and 1 case of cervical oesophageal recurrence of the head-and-neck cancer. The patients' background characteristics were not significantly different. During surgery, thoracic blood loss was significantly lower in PP than in LLDP (P = 0.0487). Other operative findings and post operative complications were not significantly different between the two groups. CONCLUSIONS: In MIPLE, the PP could reduce blood loss due to the two-lung ventilation under artificial pneumothorax and was associated with lower surgical stress than LLDP. PMID- 29582803 TI - Management of portal annular pancreas during laparoscopic pancreaticoduodenectomy. AB - Portal annular pancreas (PAP) is a pancreatic congenital anomaly consisting of pancreatic parenchyma encircling the portal vein and/or the superior mesenteric vein. It has been reported that the risk of developing a post-operative pancreatic fistula is higher following pancreaticoduodenectomy in patients with PAP, probably because of the possibility of leaving undrained a portion of pancreatic parenchyma during the reconstructive phase. Few manuscripts have reported a surgical technique of pancreaticoduodenectomy in case of PAP, herein we report the first case of a patient with PAP undergoing laparoscopic pancreaticoduodenectomy. PMID- 29582804 TI - Laparoscopic repair for parastomal hernia with ongoing barbed suture followed by sandwich-technique: 'Sandwich-plus-technique'. AB - The incidence of parastomal hernias after a permanent stoma is between 50% and 80% depending on the type of stoma, the definition of the hernia (clinical or radiological), and the length of the follow-up. Surgical therapy is complex and involves several techniques with different recurrence rates. We present three cases where we have closed the hernia gap with continuous, non-resorbable, self retaining sutures with subsequent use of the sandwich technique ('Sandwich-plus technique'). There were pronounced parastomal hernias in three female patients (mean age was 72 years and the range was 63-78 years) with permanent colostomata. After laparoscopic adhesiolysis, the closure of the hernia defect was completed with ongoing, barbed non-resorbable 1-0 sutures (polybutester) followed by the sandwich technique. There were no intraoperative complications and currently no clinical or radiological evidence for recurrences of the parastomal hernia. Closure of the hernia gap leads to the additional reconstruction of the lateral abdominal wall, resulting in a larger contact surface for integration of the keyhole mesh and thus prior to implantation of the Sugarbaker mesh. The laparoscopic augmentation of large parastomal hernias using the 'Sandwich-plus technique' is technically complex but achieves very good results in our case series. Further studies and long-term results should prove that the low recurrence rate of the sandwich technique can be further reduced. PMID- 29582805 TI - Brace up or burnout.

PMID- 29582809 TI - Concomitant use of conjunctival tissue graft from the pterygium itself without rotation in pterygium surgery: A full circle in conjunctival autografting. AB - Purpose: The aim of this study is to describe a modified technique of using conjunctival tissue from the pterygium itself without any rotation of graft for the primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium using fibrin glue. Methods: In this retrospective, noncomparative, interventional case series, 98 eyes of 98 patients with primary pterygium operated between July 2011 to July 2016 were included. They underwent this technique from the pterygium tissue itself. There was no rotation of this graft, and it was adhered to the bare scleral defect with fibrin glue. Histopathological analysis of pterygium tissue was done to look for morphology and thickness of this thin conjunctival tissue obtained from pterygium tissue itself. The primary outcome measure was recurrence rate. Other outcome measures studied was graft retraction and graft edema. Results: The mean age was 52 +/- 10.04 years. Mean follow-up was 14 +/- 8.24 months. The only significant complication was recurrence rate of 4.08% (4 eyes out of 98). The most come secondary outcome was graft edema, 52.04% (51 eyes out of 98) which resolved without any intervention. Other outcome such as graft retraction, 32.65% was also recorded. Conclusion: Conjunctival tissue from the pterygium tissue itself without actual rotation appears to be a successful technique with lower recurrence rate for treating primary pterygium in eyes with glaucoma filtering bleb, glaucoma suspects, and in primary double-head pterygium. PMID- 29582808 TI - Simplifying "target" intraocular pressure for different stages of primary open angle glaucoma and primary angle-closure glaucoma. AB - Lowering of intraocular pressure is currently the only therapeutic measure for Glaucoma management. Many longterm, randomized trials have shown the efficacy of lowering IOP, either by a percentage of baseline, or to a specified level. This has lead to the concept of 'Target" IOP, a range of IOP on therapy, that would stabilize the Glaucoma/prevent further visual field loss, without significantly affecting a patient's quality of life. A clinical staging of Glaucoma by optic nerve head evaluation and perimetric parameters, allows a patient's eye to be categorized as having - mild, moderate or severe Glaucomatous damage. An initial attempt should be made to achieve the following IOP range for both POAG or PACG after an iridotomy. In mild glaucoma the initial target IOP range could be kept as 15-17 mmHg, for moderate glaucoma 12-15 mmHg and in the severe stage of glaucomatous damage 10-12 mmHg. Factoring in baseline IOP, age, vascular perfusion parameters, and change on perimetry or imaging during follow up, this range may be reassessed over 6 months to a year. "Target" IOP requires further lowering when the patient continues to progress or develops a systemic disease such as a TIA. Conversely, in the event of a very elderly or sick patient with stable nerve and visual field over time, the target IOP could be raised and medications reduced. An appropriate use of medications/laser/surgery to achieve such a "Target" IOP range in POAG or PACG can maintain visual fields and quality of life, preventing Glaucoma blindness. PMID- 29582810 TI - Evaluation of macular ganglion cell analysis compared to retinal nerve fiber layer thickness for preperimetric glaucoma diagnosis. AB - Purpose: To compare the diagnostic ability of the ganglion cell analysis (GCA) and retinal nerve fiber layer (RNFL) protocol on optical coherence tomography (OCT), to diagnose preperimetric glaucoma. Methods: A prospective, cross sectional study of 275 adult patients including 47 early glaucoma (mean deviation better than -6.0 D), 150 glaucoma suspects (106 with suspicious discs and 44 ocular hypertensive (OHT), and 78 normal controls was done. Eligible participants were scanned with the spectral domain CirrusTM OCT (Carl Zeiss Meditec, Dublin, CA). Average peripapillary RNFL thickness and GCA measurements were obtained. Area under receiver operating characteristic (AROC) curves were used to evaluate discriminant value of both protocols to diagnose likely preperimetric glaucoma among glaucoma suspects. Results: Average RNFL and GCA were significantly thinner in glaucoma patients compared to glaucoma suspects and normal controls (P < 0.001). The RNFL was 92.26 +/- 8.8 MU in normal controls, 87.9 +/- 12.12 MU in glaucoma suspects and significantly thinner in POAG (70.29 +/- 10.18 MU; P < 0.001). The GCA was 81.94 +/- 6.17 MU in normal controls, 77.69 +/- 9.03 MU in glaucoma suspects, and significantly thinner in POAG (69.36 +/- 11.06 MU; P < 0.001). AROCs for discriminating glaucoma suspects from normal were modest, with no difference in AROC of average RNFL or GCA measurements (DeLong; P = 0.93). Average RNFL thickness had significantly greater AROC values than average GCA for discriminating glaucoma suspects (both suspicious discs and OHT) from glaucoma (P = 0.03 and 0.05, respectively. AROC for diagnosing glaucoma was significantly better (P = 0.02) for RNFL (0.88 +/- 0.03) than GCA (0.77 +/- 0.04). Conclusion: In the present time, GCA measurements, as provided by the SD-OCT, do not appear to outperform RNFL measurements in the diagnosis of preperimetric glaucoma. PMID- 29582811 TI - Application of high intensity focused ultrasound for treatment of open-angle glaucoma in Indian patients. AB - Purpose: The aim of this study is to assess the efficacy of ultrasound cycloplasty (UCP) in Indian patients with open angle glaucoma (OAG). Methods: A prospective interventional study was designed to treat 73 eyes of 73 patients with OAG with the EyeOP1 device equipped with six miniaturized cylindrical piezoelectric transducers. Two treatment protocols of ultrasound delivery depending on exposure time (8 s and 10 s of shot per transducer) were used. Complete ophthalmic examination, ocular biometry and anterior segment optical coherence tomography were performed preoperatively and patients were followed up at day 1, day 7 and months 1, 2, 3, 6, and 12. The primary outcome measure was "successful" intraocular pressure (IOP) control defined as IOP reduction >=20% from baseline and IOP value >5 mm Hg at the last follow-up visit. Secondary outcomes were the occurrence of complications and mean IOP during the follow-up period. Results: In all patients, the mean IOP reduced from 23.5 +/- 3.0 mmHg before treatment to 15.7 +/- 5.4 mmHg at 12 months (P < 0.05). Successful IOP control after a single procedure was 78.3% (79% and 78% in the 8 s and 10 s groups, respectively) at 12 months. Overall, the mean IOP reduction achieved in responding patients was 41% (standard deviation = 12%). Notwithstanding minor side effects such as transient pain, anterior chamber reaction, and refractive error changes, no major intraoperative or postoperative complications (severe hypotony or phthisis) were observed during the follow-up. Conclusion: Our short term results reveal that UCP is a simple, safe, and noninvasive procedure which enables to significantly reduce the IOP in patients with OAG. The study results in Indian eyes corroborate findings in earlier studies on Caucasian eyes. PMID- 29582812 TI - Changing uveitis patterns in South India - Comparison between two decades. AB - Purpose: Changing pattern of uveitis in a subset of a population is an important ocular health indicator. Methods: A comparative study was done between uveitis patients of 2013 and 1995 using two proportions Z-test. Results: In 2013, 352 new uveitis cases were examined. Males 56%, females 44%; unilateral 30.4%; bilateral in 69.6%. A specific diagnosis achieved in 66.2%. Anterior uveitis was seen in 35.22%, intermediate uveitis in 30.11%, posterior uveitis in 25%, and panuveitis in 9.65%. There was no significant difference in the incidence of new uveitic cases (1.04% vs. 1.8%). A decline in male preponderance from 64% to 56% (P = 0.0187) was observed. In both studies, anterior uveitis was the most common but human leukocyte antigen-B27 positivity uveitis had increased (29.83% vs. 14.5%; P < 0.05). Intermediate uveitis was the second-most common type instead of posterior uveitis (P = 0.0006). In posterior uveitis cases, etiology was established in 88.6% versus 56.06% cases (P < 0.05). The most common cause of posterior uveitis was tuberculosis (TB) (35.2%). Viral retinitis had increased to 6.81% from 0.76% (P < 0.05). However, a declining trend in cases of toxoplasmosis was observed (P = 0.0545). The cause of panuveitis was comparable in both studies. The prevalence of TB has significantly increased in the present era (22.5% vs. 0.64%; P < 0.0001) and was the proven etiological cause of uveitis in overall 22.5% of which 4.8% cases were of anterior uveitis cases, 7.1% cases of intermediate uveitis cases, 8.8% cases of posterior uveitis cases, and 1.8% of panuveitis cases. Conclusion: A shifting paradigm of uveitis over the past two decades was observed. PMID- 29582813 TI - Changing patterns in uveitis South India: Comparison between two decades. PMID- 29582814 TI - Change in choroidal vascularity in acute central serous chorioretinopathy. AB - Purpose: This study aims to compare the effect of laser photocoagulation or observation on choroidal vascularity in acute central serous chorioretinopathy (CSCR). Methods: A retrospective analysis of 30 patients with acute CSCR treated either with laser photocoagulation (16 eyes) or sham laser (14 eyes) was performed. Demographic details, visual acuity (VA) assessment, and other relevant clinical data were considered from baseline to the 3rd and 6th month follow-up visits. Participants with chronic CSCR and missing follow-up or inadequate data were excluded. Choroidal analysis including choroidal thickness and choroidal vascularity index (CVI) assessment was done for each visit using Spectral Domain (SD) Optical Coherence Tomography (OCT) images. Results: In laser arm group, there was a statistically significant change in VA, contrast sensitivity and central macular thickness (CMT) and neurosensory detachment (NSD) (P < 0.05) at the 3rd and 6th month visits. However, there was no statistically significant difference in subfoveal choroidal thickens (SFCT) and CVI (P > 0.05) at both the visits. In sham laser group, similarly, there was a significant improvement in VA, contrast sensitivity, CMT, and CVI (P < 0.05) at the 3rd and 6th month visits. There was significant reduction in NSD at the 3rd month; however, it was not statistically significant at the 6th month visit. SFCT did not change significantly at both the visits. There was no significant difference for the changes in parameters between the groups at the 6th month. Regression analysis showed no significant correlation with final VA with any of the baseline parameters. Conclusion: Early laser photocoagulation does lead to change in choroidal morphology, though insignificant, in comparison to observation. The present data, yet again, support no additional benefit of early laser photocoagulation in acute CSCR. PMID- 29582815 TI - Biochemical scenario behind initiation of diabetic retinopathy in type 2 diabetes mellitus. AB - Purpose: Despite the disease having similar glycemic status and duration microangiopathy in some patients develop within few years whereas it doesn't appear as a health complication in some diabetics for a considerable period. This study is undertaken to assess the hyperglycemia-induced biochemical background behind the development of diabetic retinopathy (DR) in type 2 diabetes mellitus (DM). Methods: Following proper diagnosis, 100 patients of type 2 DM of 10-12 years duration having no DR, and 42 patients of type 2 DM of the same duration and glycemic status as the second group, with mild retinopathy were recruited in the study. Lactic acid, glutamate, malondialdehyde (MDA), nitrate, advanced glycation end-products (AGEs), peripheral blood mononuclear cell reactive oxygen species (ROS), vascular endothelial growth factor (VEGF), and its receptor 2 (VEGFR2) in these two groups were produced in an assay following standard methodology. Results: Biochemical markers of anaerobic glycolysis, lipid peroxidation, AGEs, glutamate concentration, oxidative stress, and expression of VEGF and its VEGFR2 with significantly elevated markings were found in them who developed earliest stage of DR rather than them who had not. Conclusion: Hyperglycemia-induced anomalous glucose metabolism, lipid peroxidation, advanced glycation, glutamate toxicity, and oxidative stress create a background where apoptosis of retinal capillary endothelial cells invite increased expression of VEGF and VEGFR2, these being the crucial factors behind the development of diabetic microangiopathy. PMID- 29582816 TI - Prevalence, progression, and outcomes of diabetic retinopathy during pregnancy in Indian scenario. AB - Purpose: The objective of this study is to evaluate pattern of diabetic retinopathy (DR) during pregnancy in females with pregestational diabetes mellitus (DM). Methods: This is an ambispective observational cohort study conducted at an Indian tertiary care centre. A total of 50 pregnant females with pregestational DM were included while those with gestational DM were excluded from the study. Ocular examination (inclusive of fundus photography) was conducted and systemic parameters (inclusive of Glycated hemoglobin) were assessed during each of the 3 trimesters and 3 months postpartum. The prevalence and progression of DR during pregnancy in the study cohort were the main outcome measures. Results: Three of the 50 patients had type 1 DM while 47 had type II DM. All the patients with type I DM were insulin dependent while 19 patients with type II DM were insulin dependent. Overall prevalence of DR was 8% (4/50); 2 cases had nonproliferative DR (NPDR), and 2 had proliferative DR (PDR). During the study period, worsening was seen in both the patients with PDR and one required vitrectomy. Mean visual acuity in patients with PDR decreased from 0.77 logMAR units at presentation to 1.23 logMAR at final follow-up. There was no change in the mean visual acuity of patients with NPDR. None of the patients with NPDR converted to PDR. There was no new onset DR in the patients without DR at presentation. Assessment of risk factors for DR revealed significantly higher duration of DM (14 +/- 6.32 years vs. 3.43 +/- 1.43 years, P = 0.0008). The median age was also higher in the DR patients (31 years vs. 29 years, P = 0.32). Conclusion: No new onset cases were seen during the course of pregnancy and no conversion from NPDR to PDR was seen; however, a worsening of the two PDR cases was observed. No cases of DR were seen in noninsulin-dependent DM. None of the four participants with DR showed a spontaneous resolution of DR postpartum. Patients with PDR and long-standing DM require careful observation during pregnancy. A registry of diabetic mothers should be set up for development of guidelines for managing such cases. PMID- 29582817 TI - Diabetic retinopathy in patients with diabetic foot syndrome in South India. AB - Purpose: The purpose was to study the retinopathy status in diabetic patients with a risk of diabetic foot (DF) syndrome visiting a tertiary care hospital in South India. Methods: In this cross sectional study all patients with diabetes mellitus (DM) with a risk of DF syndrome, visiting a tertiary care hospital during the study period, underwent an ophthalmological evaluation for documentation of their retinopathy status. Results: One hundred and eighty-two patients diagnosed to have a risk profile for DF syndrome were included in the study. Their mean age was 59.28 years and 75.27% were males. The mean duration of Type 1 and Type 2 variants of DM was 14.9 years and 10.9 years, respectively. Of the 182 patients, 67.58% had retinopathy changes. Proliferative diabetic retinopathy (DR) constituted 17.88% of the total patients with retinopathy. An increased presence of retinopathy in patients with an increased risk grade of DF was found significant by the Chi-square test (P < 0.001). Conclusion: Our study found an increased presence of DR in a South Indian cohort with DF syndrome. The severity of retinopathy was greater in patients with higher grades of risk for DF. The establishment of an association between DR and DF syndrome will help in developing an integrated management strategy for these two debilitating consequences of diabetes. PMID- 29582818 TI - Association of exudative age-related macular degeneration with matrix metalloproteinases-2 (-1306 C/T) rs243865 gene polymorphism. AB - Purpose: Age-related macular degeneration (AMD) is a disease of the macula that significantly affects eyesight and leads to irreversible central vision loss. Recent studies have demonstrated that angiogenesis is the most important mechanism of AMD development. It is associated with extracellular remodeling involving different proteolytic systems, among them matrix metalloproteinases (MMPs), which play an essential role in the etiopathogenesis of AMD. The main objective of the present study was to determine the relationship between exudative AMD and MMP-2 (-1306 C/T) rs243865 polymorphism. Methods: The study enrolled 267 patients with exudative AMD and 318 controls. DNA was extracted from peripheral venous blood leukocytes by commercial kits. Genotyping of MMP-2 (-1306 C/T) rs243865 was carried out using real-time polymerase chain reaction method. Results: The analysis of MMP-2 (-1306 C/T) polymorphism did not reveal any differences in the distribution of CC, CT, and TT genotypes between the exudative AMD and control groups: 58.8%, 31.5% and 9.7% vs. 59.75%, 33.96% and 6.29%, respectively, P = 0.287). When the study population was subdivided into age groups, MMP-2 (-1306 C/T) rs243865 CT genotype showed 5.7-fold increased the risk of exudative AMD development compared to CC and TT genotypes together in younger (<65 years) males group (P = 0.05). Conclusion: MMP-2 (-1306 C/T) polymorphism is associated with exudative AMD development in younger males. PMID- 29582819 TI - Vitreous rebleed following sutureless vitrectomy: Incidence and risk factors. AB - Purpose: This study aims to evaluate the incidence and risk factors for vitreous rebleed (VRB) following 25-gauge sutureless vitrectomy for vitreous hemorrhage (VH) in diabetic retinopathy. Methods: A retrospective review of 190 diabetic patients having undergone vitrectomy for VH at a tertiary eye care center was analyzed. Demographic data of patients along with risk factors such as blood sugar levels (BSL), blood pressure (BP), anticoagulant use, and pan-retinal photocoagulation status (PRP) were tabulated. Depending on the commencement of VRB, patients were divided into immediate rebleed-within 2 weeks and delayed rebleed-beyond 2-4 weeks. Results: Forty-one patients had VRB, out of which 18 patients had immediate VRB and 23 patients had delayed VRB. The average duration between vitrectomy and VRB was 3.28 months. Twenty-eight patients were male and 13 were females. Average age at presentation was 53.8 years. Thirty-four patients (82.9%) were found to have high BSL and 28 patients (68.3%) had high BP and they developed rebleed (P < 0.01) after an initial hemorrhage-free period (average = 5.15 months). Fifteen patients (36.6%) underwent first time PRP intraoperatively, and they had immediate rebleed (P < 0.01) without any hemorrhage-free period (average = 0.9 months). Eight patients (19.5%) were on perioperative anticoagulants; however, their statistical significance did not persist in the multivariable model. There were neither age nor gender predilection toward rebleed (P > 0.05). Conclusion: The incidence rate of VRB was found to be 21.6%. Age and gender did not contribute to rebleed. Intraoperative PRP was a risk factor for immediate rebleed. Poor glycemic and BP control was a risk factor for delayed rebleed. PMID- 29582821 TI - Pars-plana fluid aspiration for positive vitreous cavity pressure in anterior segment surgeries. AB - Positive vitreous pressure due to misdirection of aqueous or choroidal effusion leads to shallowing of the anterior chamber (AC) before or during anterior segment surgeries. This shallow AC if not addressed makes surgery difficult and increases the risk of surgical complications. Methods to prevent and manage this condition described in literature are not without problems. We describe a minimally invasive technique of passing a 30G needle through the pars-plana to aspirate misdirected fluid from vitreous cavity either as a prophylaxis just before surgery or during it, thereby decreasing positive vitreous pressure. This technique, used in 12 eyes, seems to be effective in patients with angle-closure glaucoma, malignant glaucoma, and per-operative sudden increase in vitreous pressure during surgery. Small-incision surgeries are ideally suited for this procedure. This minimally invasive technique is simple to perform and complications are unlikely to be more than what is seen with intravitreal injections.

AB - We describe a surgical technique for the correction of isolated congenital lenticular coloboma associated with high corneal astigmatism. Transscleral fixation of the capsular bag with a single eyelet Cionni capsular tension ring was followed by in-the-bag implantation of a toric intraocular lens (IOL). This lead to complete correction of the lenticular defect and perfect alignment of the toric lens. In this case, the child attained an unaided distance visual acuity of 20/30 following amblyopia therapy and a well-aligned toric IOL at 12 months of follow-up. This technique can be used in cases with concomitant lenticular coloboma and significant corneal astigmatism. PMID- 29582822 TI - Floating venous loop in regressed retinopathy of prematurity.

AB - Actinomyces israelii is a Gram-positive anaerobic organism commonly associated with canaliculitis in adults. Pediatric canaliculitis is relatively rare, especially in infancy. We report the case of an 11-month-old boy who presented with co-existing canaliculitis and congenital nasolacrimal obstruction. The presenting signs included epiphora, discharge, conjunctival congestion, and matting of lashes. On examination, punctual pouting, regurgitation, and yellow canaliculiths were noted. A punctoplasty and canalicular curettage were performed along with nasolacrimal probing. Microbiological tests confirmed the organisms to be A. israelii. We discuss the clinical features and management of Actinomyces associated canaliculitis and review the available literature on pediatric canaliculitis.

AB - Allergic conjunctival granuloma is a rare cause of conjunctival ocular lesions. The aim of this case report was to present a successful treatment of an allergic conjunctival granuloma with topical tacrolimus eye drops. A 20-year-old female presented with bilateral multiple yellow nodules of the bulbar conjunctival epithelium and conjunctival injection. The patient had tearing, photophobia, itching, foreign body sensation, and red eye. The patient's signs and symptoms progressed despite the use of topical steroids. The patient was treated by application of tacrolimus eye drop (0.005%) in her right eye every 6 h while the left eye was put on placebo. Her signs and symptoms were recorded at each visit. After 3 weeks' therapy with topical tacrolimus eye drop, the patient became asymptomatic in her right eye and conjunctival granulomas fully resolved. Topical tacrolimus seems to be an effective therapeutic option for the treatment of allergic conjunctival granulomas.

All cases underwent OCT angiography with swept source OCTA (Topcon DRI OCT Triton plus) 6 mm * 6 mm protocol. OCTA at the level of large choroidal vessels demonstrated peculiar vascular pattern in all four eyes. Patterns observed were bag of worms, spaghetti like and vessels with terminal bulbs. In eye with diffuse choroidal hemangioma comparison of choroidal vascular pattern with the contralateral eyes showed significant difference in the vascular architecture. OCTA is an excellent non invasive tool in assessing the choroidal vascular pattern in eyes with choroidal hemangioma. PMID- 29582829 TI - Choroidal osteoma in a preterm infant. AB - Choroidal osteoma (CO) is a rare, benign, and usually unilateral intraocular tumor composed of mature bone affecting the choroid. It appears as slightly elevated, yellowish-white, or orange choroidal mass with well-defined borders. It is commonly encountered in young female adults. Here, we report findings of a 4 week-old premature baby with CO in her left eye which was detected during a routine examination for "retinopathy of prematurity." We believe that this case is the youngest patient reported with CO which showing that this pathology can be encountered even in a newborn.

AB - Choroidal nodules in neurofibromatosis type-1 are common and are best imaged with near-infrared reflectance (NIR) imaging. The authors describe swept-source optical coherence tomography angiography (SSOCTA) of choroidal nodules. These nodules are seen as hyperflow areas on SSOCTA and correlate well to bright patches on NIR imaging. The utility of multicolor scanning laser imaging in detecting these abnormalities is also described. PMID- 29582831 TI - A rare case of unilateral diffuse melanocytic proliferation. AB - A 67-year-old woman presented with metamorphopsia in the right eye. Leopard mottling was seen temporal to the fovea oculus dexter with corresponding hyper- and hypo-autofluorescent lesions on fundus autofluorescence. Spectral domain optical coherence tomography revealed hyperreflective dots in the retinal pigment epithelium and choroid with subretinal fluid (SRF). Intravitreal bevacizumab was administered with which SRF resolved, albeit with increase in the areas of mottling. The patient was diagnosed to have metastatic ductal carcinoma of the right breast. It is important to bear in mind that the well-known entity of bilateral diffuse uveal melanocytic proliferation can rarely present unilaterally. PMID- 29582832 TI - Progressive outer retinal necrosis after rituximab and cyclophosphamide therapy. AB - We report a case of progressive outer retinal necrosis (PORN) in a patient of microscopic polyangitis (MPA), being treated with immunosuppressive drugs such as cyclophosphamide and rituximab. Her aqueous tap was positive for Varicella Zoster virus and she was treated with oral and intravitreal antivirals, along with discontinuation of one of the immunosuppressive agents, i.e. rituximab, which might have led to reactivation of the virus causing necrotizing retinitis lesions. Rituximab and cyclophosphamide are extremely potent drugs, which are necessary to manage immunological disorders such as MPA. However, they may predispose the patient to serious complications like viral infections, including PORN.

PMID- 29582843 TI - A framework for comparative analysis of health systems: experiences from the Asia Pacific Observatory on Health Systems and Policies. AB - Drawing on published work from the Asia Pacific Observatory on Health Systems and Policies, this paper presents a framework for undertaking comparative studies on the health systems of countries. Organized under seven types of research approaches, such as national case-studies using a common format, this framework is illustrated using studies of low- and middle-income countries published by the Asia Pacific Observatory. Such studies are important contributions, since much of the health systems research literature comes from high-income countries. No one research approach, however, can adequately analyse a health system, let alone produce a nuanced comparison of different countries. Multiple comparative studies offer a better understanding, as a health system is a complex entity to describe and analyse. Appreciation of context and culture is crucial: what works in one country may not do so in another. Further, a single research method, such as performance indicators, or a study of a particular health system function or component, produces only a partial picture. Applying a comparative framework of several study approaches helps to inform and explain progress against health system targets, to identify differences among countries, and to assess policies and programmes. Multi-method comparative research produces policy-relevant learning that can assist countries to achieve Sustainable Development Goal 3: ensure healthy lives and promoting well-being for all at all ages by 2030. PMID- 29582844 TI - Pushing the boundaries of research on human resources for health: fresh approaches to understanding health worker motivation. AB - A country's health workforce plays a vital role not only in serving the health needs of the population but also in supporting economic prosperity. Moreover, a well-funded and well-supported health workforce is vital to achieving universal health coverage and Sustainable Development Goal 3 to ensure healthy lives and promote well-being for all at all ages. This perspective article highlights the potential of underutilized health policy and systems research (HPSR) approaches for developing more effective human resources for health policy. The example of health worker motivation is used to showcase four types of HPSR (exploratory, influence, explanatory and emancipatory) that move beyond describing the extent of a problem. Most of the current literature aiming to understand determinants and dynamics of motivation is descriptive in nature. While this is an important basis for all research pursuits, it often gives little information about mechanisms to improve motivation and strategies for intervention. Motivation is an essential determinant of health worker performance, particularly for those working in difficult conditions, such as those facing many health workers in low- and middle-income countries. Motivation mediates health workforce performance in multiple ways: internally governing health worker behaviour; informing decisions on becoming a health worker; workplace location and ability to perform; and influencing willingness to engage politically. The four fresh research approaches described can help policy-makers better understand why health workers behave the way they do, how interventions can improve performance, the mechanisms that lead to change, and strategies for empowering health workers to be agents of change themselves. PMID- 29582845 TI - The burden of iron-deficiency anaemia among women in India: how have iron and folic acid interventions fared? AB - Iron-deficiency anaemia (IDA) among women in India is a problem of major public health significance. Using data from three waves of the National Family Health Survey, this article discusses the burden of and trend in IDA among women in India, and discusses the level of iron and folic acid (IFA) supplementation and its potential role in reducing the burden of IDA. Between 2005-2006 and 2015 2016, IDA in India decreased by only 3.5 percentage points (from 56.5% in 2005 2006 to 53.0% in 2015-2016) for women aged 15-49 years. However, during the same period, of 27 states compared, IDA increased in eight: Delhi, Haryana, Himachal Pradesh, Kerala, Meghalaya, Tamil Nadu, Punjab and Uttar Pradesh; furthermore, some of these (e.g. Kerala) are states that rank among the highest on the state Human Development Index but had failed to contain the burden of IDA. Although there is a standard guideline for IFA supplementation in place, the IFA intervention appears to be ineffective in reducing the burden of IDA in India (nationally only 30.3 % of mothers consumed IFA for 100 days or more when they were pregnant), probably due to irregular consumption of IFA where the provision of screening under the National Iron+ Initiative scheme appears to be unsuccessful. To strengthen the IFA intervention and its uptake, a concerted effort of community-level health workers (accredited social health activists, auxiliary nurse midwives and anganwadi workers) is urgently needed. In addition, food-based strategies (dietary diversification and food fortification), food supplementation and improvement of health services are required to reduce the burden of anaemia among women in India. PMID- 29582846 TI - Social autopsy: a potential health-promotion tool for preventing maternal mortality in low-income countries. AB - Despite significant global improvements, maternal mortality in low-income countries remains unacceptably high. Increasing attention in recent years has focused on how social factors, such as family and peer influences, the community context, health services, legal and policy environments, and cultural and social values, can shape and influence maternal outcomes. Whereas verbal autopsy is used to attribute a clinical cause to a maternal death, the aim of social autopsy is to determine the non-clinical contributing factors. A social autopsy of a maternal death is a group interaction with the family of the deceased woman and her wider local community, where facilitators explore the social causes of the death and identify improvements needed. Although still relatively new, the process has proved useful to capture data for policy-makers on the social determinants of maternal deaths. This article highlights a second aspect of social autopsy - its potential role in health promotion. A social autopsy facilitates "community self-diagnosis" and identification of modifiable social and cultural factors that are attributable to the death. Social autopsy therefore has the potential not only for increasing awareness among community members, but also for promoting behavioural change at the individual and community level. There has been little formal assessment of social autopsy as a tool for health promotion. Rigorous research is now needed to assess the effectiveness and cost effectiveness of social autopsy as a preventive community-based intervention, especially with respect to effects on social determinants. There is also a need to document how communities can take ownership of such activities and achieve a sustainable impact on preventable maternal deaths. PMID- 29582847 TI - Current status of master of public health programmes in India: a scoping review. AB - There is a recognized need to improve training in public health in India. Currently, several Indian institutions and universities offer the Master of Public Health (MPH) programme. However, in the absence of any formal body or council for regulating public health education in the country, there is limited information available on these programmes. This scoping review was therefore undertaken to review the current status of MPH programmes in India. Information on MPH programmes was obtained using a two-step process. First, a list of all institutions offering MPH programmes in India was compiled by use of an internet and literature search. Second, detailed information on each programme was collected via an internet and literature search and through direct contact with the institutions and recognized experts in public health education. Between 1997 and 2016-2017, the number of institutions offering MPH programmes increased from 2 to 44. The eligibility criteria for the MPH programmes are variable. All programmes include some field experience. The ratio of faculty number to students enrolled ranged from 1:0.1 to 1:42. In the 2016-2017 academic year, 1190 places were being offered on MPH programmes but only 704 students were enrolled. MPH programmes being offered in India have witnessed a rapid expansion in the past two decades. This growth in supply of public health graduates is not yet matched by an increased demand. Despite the recognized need to strengthen the public health workforce in India, there is no clearly defined career pathway for MPH graduates in the national public health infrastructure. Institutions and public health bodies must collaborate to design and deliver MPH programmes to overcome the shortage of public health professionals, such that the development goals for India might be met. PMID- 29582848 TI - Factors associated with delivery at home in Bhutan: findings from the National Health Survey 2012. AB - Background: Despite Bhutan's remarkable progress in the area of maternal and child health during the era of the Millennium Development Goals, a large proportion of pregnant women are still delivering at home with no skilled attendant. Limited empirical studies have been carried out to understand the factors associated with delivery at home in Bhutan. Methods: This cross-sectional analytical study used secondary data collected in the nationally representative National Health Survey 2012. The survey included a total of 2213 women aged 15-49 years who had a live birth in the 2 years preceding the survey and were selected using multistage stratified cluster sampling. Weighted analysis was done to evaluate determinants for the place of delivery. Unadjusted and adjusted prevalence ratios with 95% confidence intervals (CIs) were calculated to assess the possible association of factors with home delivery. Results: Out of 2213 women aged 15-49 years who had a live birth in the 2 years preceding the survey, 73.7% had an institutional delivery. Coverage of institutional delivery ranged from 49.4% in Zhemgang district to 96.1% in Paro district. Women in the poorest wealth quintile were 7.35 times more likely to have a birth at home compared to women in the richest quintile (adjusted prevalence ratio [aPR]: 7.35, 95% CI: 2.59-20.9). The older mothers aged 30-49 years were 0.79 times (aPR: 0.79, 95% CI: 0.70-0.88) less likely to have a home delivery than mothers aged 15-19 years. Women who had fewer than four antenatal care visits were 1.50 times (aPR: 1.50, 95% CI: 1.35-1.66) more likely to give birth at home compared to those who had four or more visits. The mothers giving birth for a third or more time were 1.88 times (aPR: 1.88, 95% CI: 1.60-2.22) more likely to give birth at home compared to those giving birth for the first time. Women living in rural areas were 2.87 times (aPR: 2.87, 95% CI: 1.42-5.77) more likely to deliver at home compared to those living in urban areas and women living in the eastern region of the country were 1.35 times (aPR: 1.35, 95% CI: 1.17-1.55) more likely to have a home delivery compared to those living in the western region. Conclusion: Lower socioeconomic status, rural location, eastern location, non- first birth, and having fewer than four antenatal visits were significant factors associated with home delivery. These findings should inform further research and policy to build on Bhutan's progress in promoting institutional delivery as the key strategy towards improving maternal and child health and achieving the relevant targets of Sustainable Development Goal 3. PMID- 29582849 TI - Changes in neonatal mortality and newborn health-care practices: descriptive data from the Bangladesh Demographic and Health Surveys 2011 and 2014. AB - Background: Bangladesh has made major improvements in health outcomes over the past two decades, with falls in mortality rates in mothers and in infants and young children aged under 5 years. Despite these improvements, neonatal mortality rates (NMRs) are high in Bangladesh. This paper describes recent changes in NMRs and health-care practices, disaggregated by demographic and socioeconomic characteristics. Methods: Summary statistics from the reports of the Bangladesh Demographic and Health Survey (BDHS) were examined. The BDHS is a nationally representative cross-sectional survey and the two most recent rounds of surveys, 2007-2011 and 2010-2014, were included in the analysis. The variables considered in this study were neonatal deaths and related health-care practices, including antenatal care visits, facility-based delivery, assistance from a medically trained provider during delivery, postnatal care from a trained provider and essential newborn care. Results: Between the two survey periods, NMRs increased in Chittagong (average increase 4.5% per year) and Khulna (8.3% per year), remained unchanged in Rangpur, and decreased in Barisal (average decrease 19.8% per year), Dhaka (12.2% per year), Rajshahi (7.7% per year) and Sylhet (4.8% per year). A larger average annual reduction in the NMR was observed in urban areas than in rural areas (14.0% versus 2.1%). There was also a large average annual reduction in NMR in the fourth and fifth richest quintiles for socioeconomic status (SES quintiles; 12.0% and 16.5% per year, respectively). Differences according to neonatal sex were also noted: the NMR for female neonates remained unchanged and that for male neonates reduced by an annual average of 7.7%. General improvements were observed in all health-care practices across all demographic and socioeconomic groups. However, the urban-rural gap in the uptake of antenatal care services, facility-based delivery, assistance from a medically trained provider during delivery, and postnatal care from a trained provider was roughly similar in both surveys. A similar unchanging gap was also seen between the poorest and richest SES quintiles. Conclusion: The study analysis indicates that improvements in NMRs between the two survey periods are mixed. Further attention is required to improve the rate of reduction of neonatal mortality in some divisions in Bangladesh, and it may be useful to investigate whether the higher NMR in rural areas and for households with lower socioeconomic status can be reduced by strengthening the uptake of antenatal care services, facility-based delivery, assistance from a medically trained provider during delivery, and postnatal care from a trained provider. The static NMR for female neonates may encourage policy-makers to focus not only on ensuring standard essential newborn care practices for both sexes but also on ensuring adequate and appropriate care seeking for illness in female neonates. PMID- 29582850 TI - Large-scale mHealth professional support for health workers in rural Maharashtra, India. AB - Expanding mobile telephony in India has prompted interest in the potential of mobile-telephone health (mHealth) in linking health workers in rural areas with specialist medical advice and other professional services. In 2012, a toll-free helpline offering specialist medical advice to community-based health workers throughout Maharashtra was launched. Calls are handled via a 24 h centre in Pune, staffed by health advisory officers and medical specialists. Health advisory officers handle general queries, which include medical advice via validated algorithms; blood on-call services; grievance issues; and mental health support - the latter calls are transferred to a qualified counsellor. Calls requiring more specialist advice are transferred to the appropriate medical specialist. This paper describes the experience of the first 4 years of this helpline, in terms of the services used, callers, nature of calls, types of queries serviced and lessons learnt. In the first 4 years of the helpline, 669 265 calls were serviced. Of these calls, 453 373 (67.74%) needed medical advice and were handled by health advisory officers. Specialist services were required to address 199 226 (29.77%) calls. Blood-bank-related services accounted for 7919 (1.18%) calls, while 2462 (0.37%) were grievance calls. Counselling for mental health issues accounted for 6285 (0.94%) calls. The large-scale mHealth professional support provided by this helpline in Maharashtra has reached many health workers serving rural communities. Future work is required to explore ways to expand the reach of the helpline further and to measure its effectiveness in improving health outcomes. PMID- 29582851 TI - gammadelta T Cells in Peripheral Blood of Glioma Patients. AB - BACKGROUND Glioma is a common brain malignancy, but the effects of the gammadelta T cells and their subsets in peripheral blood in patients with glioma have not been reported. MATERIAL AND METHODS Flow cytometry was used to analyze the functions and expressions of delta T cells and their subsets in peripheral blood in healthy controls and patients with glioma. The Vdelta2 T cells and the activation of killing function-related signaling pathway were analyzed by Western blot assay; the immunosuppressive functions of Vdelta1 T cells were detected by CFSE proliferation assay; and the Vdelta2 T cell killing functions were detected by killing assay. RESULTS Compared with the healthy controls, the ratio of Vdelta1 T cells was significantly increased and the ratio of Vdelta2 T cells was significantly decreased. After in vitro culture and anti-TCR gd antibody stimulation and in the presence of IL-2, in the patients with glioma, the Vdelta1 T cells dominated and Vdelta2 T cells were scarce. Flow cytometry staining showed that expression of immunosuppression-related molecules on the Vdelta1 T cell surface was significantly increased, while the expression of killing function related molecules and the activation of killing function-related signaling pathway in the Vdelta2 T cells were significantly decreased. Functional test results showed that the immunosuppressive function of Vdelta1T cells was enhanced and the killing function of Vdelta1T cells was reduced. CONCLUSIONS The ratio and function changes of Vdelta1 T cells and Vdelta2 T cells are possibly associated with the pathogenesis of glioma.

PMID- 29582853 TI - [Analysis of the effectiveness of assisted reproduction techniques]. AB - There are a high number of people affected by infertility who require assisted reproduction techniques. For this reason the aim of this review was to analyze the effectiveness of the interventions carried out using these techniques. A systematic peer review was performed on twelve databases. Inclusion criteria were: randomized clinical trials, published between 2011 and 2016, and with a score greater than two on the Jadad scale. The pharmacological interventions that proved effective were the administration of hormones, intrauterine human chorionic gonadotropin, gonadotrophin and dehydroepiandrosterone, and metformin. An effective surgical intervention, endometrial scratching, was identified. No effective non-pharmacological interventions were found. Assisted reproduction techniques show heterogeneity in both the interventions included and effectiveness criteria (pregnancy rate, live birth rate or implantation rate), which makes a unification of criteria necessary.

AB - BACKGROUND: To evaluate the effects on healthcare quality following implementation of a program to improve care for individuals with headache in two physical therapy clinics and its association with outcomes and self-perceived improvement. METHODS: We assessed healthcare quality by creating a questionnaire on fulfilment of fifteen quality criteria included in the clinical history of individuals suffering from tension-type, cervicogenic or migraine headaches seeking physical therapy between 2010 and 2014. In 2015, after applying a program to improve care in one center (C1), we reassessed the same fulfilment questionnaire in both centers, using the other center (C2) as control. RESULTS: In the first evaluation there was a huge number of cases of non-compliance of all the criteria in both centers. After implementation of the care improvement program in C1 a significant improvement was observed in some items, as use of a headache diary, which rose from 0 to 100%, or use of the HIT-6 disability questionnaire, which rose from 30 to 100%. In addition, there was a significant improvement in self-perceived health status after implementation of the care program in C1. CONCLUSIONS: The implementation of a care improvement program was effective in improving healthcare quality for individuals with headache attending physical therapy services. PMID- 29582857 TI - Gastric ischemia due to critical stenosis of the celiac trunk. AB - Gastric ischemia (GI) results from diffuse or localized vascular insufficiency caused by different aetiologies such as systemic hypotension, vasculitis, disseminated thromboembolism and celiac or mesenteric stenosis. We present a case of gastric ischemia due to critical stenosis of the celiac artery treated using endovascular therapy. The celiac artery is the first major branch of the abdominal aorta and provides some of the blood supply to the stomach through the left gastric artery and other organs like the spleen (splenic artery branch) and the liver. Although the collateral blood supply to the stomach is protective, systemic hypotension or occlusion of the main arteries, as in the case of our patient, may result in gastric ischemia. The stent placement is an alternative to surgery in patients with high comorbidity and with good outcomes. The clinical awareness of this syndrome will allow gastroenterologists and radiologists to appropriately diagnose and manage affected patients.

AB - AIMS: Critically ill patients undergoing aggressive fluid resuscitation and treated empirically with hydrosoluble time-dependent beta-lactam antibiotics are at risk for sub-therapeutic plasma concentrations. The aim of this study was to assess the impact of two covariates - creatinine clearance (Clcr) and cumulative fluid balance (CFB) on pharmacokinetics/pharmacodynamics (PK/PD) target attainment within a week of treatment with meropenem (ME) or piperacillin/tazobactam (PIP/TZB). METHODS: In this prospective observational pharmacokinetic (PK) study, 18 critically ill patients admitted to a surgical Intensive Care Unit (ICU) were enrolled. The primary PK/PD target was free antibiotic concentrations above MIC at 100% of the dosing interval (100%fT>MIC) to obtain maximum bactericidal activity. Drug concentration was measured using liquid chromatography-tandem mass spectrometry. RESULTS: The treatment of both 8 septic patients with IV extended ME dosing 2 g/3 h q8 h and 10 polytraumatized patients with IV intermittent PIP/TZB dosing 4.0/0.5 g q8 h was monitored. 8/18 patients (44%) manifested augmented renal clearence (ARC) where Clcr >=130 mL/min/1.73 m2. Maximum changes were reported on days 2-3: the median positive CFB followed by the large median volume of distribution: Vdme=70.3 L (41.9 101.5), Vdpip = 46.8 L (39.7-60.0). 100%fTme>MIC was achieved in all patients on ME (aged >=60 years), and only in two patients (non-ARC, aged >=65 years) out of 10 on PIP/TZB. A mixed model analysis revealed positive relationship of CFBpip with Vdpip (P=0.021). CONCLUSION: Assuming that the positive correlation between CFB and Vd exists for piperacillin in the setting of the pathological state, then CFB should predict Vdpip across subjects at each and every time point.

The mild synthetic conditions effectively minimize the defects introduced during the conventional synthesis and endow PAQD24 with desirable optical properties, including a narrow emission band (full width at half maximum = 55 nm), an optimal quantum yield of 32.5% and two-photon fluorescence. Furthermore, the bandgap of PAQD24 is highly sensitive toward pH variations in the near-neutral region, due to the proton doping and dedoping of the PANI structure. Such unique properties together with its fine bio-compatibility enable the application of this material as a turn-on fluorescent probe for the labeling of acidic biotargets from sub-cellular to organ levels, providing potential applications in diagnosis and surgery guidance for certain diseases. PMID- 29582862 TI - Photodynamic effect of zinc porphyrin on the promastigote and amastigote forms of Leishmania braziliensis. AB - Leishmaniasis is a neglected disease present in more than 88 countries. The currently adopted chemotherapy faces challenges related to side effects and the development of resistance. Photodynamic therapy (PDT) is emerging as a therapeutic modality for cutaneous leishmaniasis. Zn(ii) meso-tetrakis(N ethylpyridinium-2-yl)porphyrin (ZnTE-2-PyP4+, ZnP) is a cationic, water-soluble, zinc porphyrin-based photosensitizer whose photodynamic effect on Leishmania braziliensis was analyzed by evaluating the number of visibly undamaged and motile cells, cell membrane integrity, mitochondrial membrane potential, and ultrastructural damage. Treatment of parasites with ZnP and light induced damage in up to 90% of L. braziliensis promastigote cells. Propidium iodide labeling suggested the loss of plasma membrane integrity. In samples treated with ZnP and light, a hyperpolarization of the mitochondrial membrane potential was also observed. Ultrastructural evaluation of promastigotes after photodynamic treatment indicated a loss of cytoplasmic material and the presence of vacuoles. Scanning electron microscopy showed wrinkling of the plasma membrane and a reduced cell volume. Additionally, the number of amastigotes per macrophage was reduced by about 40% after photodynamic application. The treatment showed no considerable toxicity against mammalian cells. Therefore, the results indicated that PDT associated with ZnTE-2-PyP4+ represents a promising alternative to cutaneous leishmaniasis treatment. PMID- 29582871 TI - A stable layered P3/P2 and spinel intergrowth nanocomposite as a long-life and high-rate cathode for sodium-ion batteries. AB - Layered sodium transition-metal oxides, NaxMeO2, with large theoretical capacity are regarded as an important class of cathode materials for sodium-ion batteries (SIBs). However, they usually exhibit inferior thermodynamic stability and sluggish Na+ kinetics due to the unwanted phase transitions and large Na+-ionic radius. In this work, considering the beneficial synergistic effects of layered P2/P3 and Fd3[combining macron]m spinel phases, a stable layered/spinel intergrowth nanocomposite Na0.5[Ni0.2Co0.15Mn0.65]O2 is rationally designed and successfully prepared via a co-precipitation route and a subsequent solid-state reaction, and the triphase synergy in this layered/spinel nanocomposite is demonstrated. In Na/Na0.5[Ni0.2Co0.15Mn0.65]O2 half-cells, it delivers a high specific capacity of ~180 mA h g-1 and a good cycling stability, with a capacity retention of 87.6% after 100 cycles, at a rate of 0.1C between 1.5 and 4.0 V (vs. Na/Na+). The large reversible capacity of 105 mA h g-1 is also achieved even at a high rate of 10C, indicating high-rate capability. Besides, the full-cells using this nanocomposite as the cathode and hard carbon as the anode exhibit long-term cycle-life and high-power properties, indicating the expected merits of layered/spinel mixed phases. The superior sodium storage performance of this layered P3/P2 and spinel intergrowth nanocomposite makes it a promising candidate as a long-life and high-rate cathode for SIBs. PMID- 29582873 TI - Persulfate-promoted oxidative C-N bond coupling of quinoxalinones and NH sulfoximines. AB - The persulfate-meditated oxidative C-N bond coupling of the C-H bond of quinoxalinones and the N-H bond of NH-sulfoximines is reported. The reaction proceeds smoothly under transition metal-free conditions and provides good to excellent yields of sulfoximidoyl-functionalized quinoxalinone products under mild conditions. The optimized conditions were found to be suitable for a range of sulfoximine and quinoxalinone substrates. This reaction offers a new and convenient strategy to directly install the sulfoximine moiety into the C3 position of quinoxalinone. PMID- 29582875 TI - Facile synthesis of a two-photon fluorescent probe based on pyrimidine 2 isothiocyanate and its application in bioimaging. AB - Two-photon microscopy imaging has been widely applied in biological imaging, but the development of two-photon absorption probes is obviously lagging behind in the development of imaging technology. In this paper, a two-photon fluorescent probe (1) based on pyrimidine 2-isothiocyanate has been designed and synthesized through a simple method for two-photon biological imaging. Probe 1 was able to couple effectively with the amino groups on biomolecules. To verify the reactivity of the isothiocyanate group on probe 1 and the amine groups on the biomolecules, d-glucosamine was chosen as a model biomolecule to conjugate with probe 1. The result showed that probe 1 could effectively conjugate with d glucosamine to synthesize probe 2, and the yield of probe 2 was 83%. After conjugating with d-glucosamine, linear absorption spectra, single-photon fluorescence spectra, and two-photon fluorescence spectra of probes 1 and 2 did not present significant changes. Probes 1 and 2 exhibited high fluorescence quantum yields (0.71-0.79) in toluene and chloroform. They also exhibited different photo-physical properties in solvents with different polarities. The two-photon absorption cross-section of probe 1 was 953 GM in toluene. In addition, probe 1 could be effectively conjugated with transferrin, and the conjugated probe (Tf-1) could be transported into Hep G2 cells through a receptor mediated process for biological imaging. These results demonstrate that such probes are expected to have great potential applications in two-photon fluorescence bioimaging. PMID- 29582876 TI - Appropriate strategies for South Africa for the management of acute myocardial infarction in patients presenting with ST-segment elevation. PMID- 29582877 TI - The proportion of South Africans living within 60 and 120 minutes of a percutaneous coronary intervention facility. AB - INTRODUCTION: Timely reperfusion, preferably via percutaneous coronary intervention (PCI) following myocardial infarction, improves mortality rates. Emergency medical services play a pivotal role in recognising and transporting patients with ST-elevation myocardial infarction directly to a PCI facility to avoid delays to reperfusion. Access to PCI is, in part, dependant on the geographic distribution of patients around PCI facilities. The aim of this study was to determine the proportion of South Africans living within 60 and 120 minutes of a PCI facility. METHODS: PCI facility and population data were subjected to proximity analysis to determine the average drive times from municipal ward centroids to PCI facilities for each province in South Africa. Thereafter, the population of each ward living within 60 and 120 minutes of a PCI facility was extrapolated. RESULTS: Approximately 53.8 and 71.53% of the South African population live within 60 and 120 minutes of a PCI facility. The median (IQR, range) drive times and distances to a PCI facility are 100 minutes (120.4 min, 0.7-751.8) across 123.6 km (157.6 km, 0.3-940.8). CONCLUSION: Based on the proximity of South Africans to PCI facilities, it seems possible that most patients could receive timely PCI within 120 minutes of first medical contact. However, this may be unlikely for some due to a lack of medical insurance, under developed referral networks or other system delays. Coronary care networks should be developed based on the proximity of communities to 12-lead ECG and reperfusion therapies (such as PCI facilities). Public and private healthcare partnerships should be fortified to allow for patients without medical insurance to have equal accesses to PCI facilities. PMID- 29582878 TI - Value of transluminal attenuation gradient of stress CCTA for diagnosis of haemodynamically significant coronary artery stenosis using wide-area detector CT in patients with coronary artery disease: comparison with stress perfusion CMR. AB - INTRODUCTION: This study aimed to evaluate the value of transluminal attenuation gradient (TAG) of stress coronary computed tomography angiography (CCTA), using a wide-area detector CT in patients with coronary artery disease, compared to stress perfusion cardiac magnetic resonance (CMR) imaging. METHODS: This prospective study from May 2012 to January 2015 included 21 patients with moderate coronary stenosis on invasive coronary angiography. All patients underwent adenosine stress single-shot CCTA with a rest CCTA scan using a wide area detector CT. Coronary artery stenosis was evaluated on both stress and rest CCTA images, and TAG was manually obtained for all vessels. Stress perfusion CMR was used as a reference standard. A TAG cut-off value of -15.1 HU/10 mm was applied for diagnosing haemodynamically significant stenosis. The diagnostic accuracies of TAG and CMR were estimated and compared. RESULTS: TAG of stress CCTA in all coronary arteries had a sensitivity, specificity, and positive and negative predictive values of 90.5, 90.0, 86.4 and 93.1%, respectively. Corresponding values for TAG of rest CCTA in all coronary arteries were 42.9, 83.3, 64.3 and 67.6%, respectively, whereas those for TAG of coronary arteries with moderate stenosis on stress CCTA were 93.3, 100, 100 and 92.3%, respectively. Mean effective radiation doses for stress and rest CCTA were 10.6 +/- 2.6 mSv and 2.3 +/- 1.3 mSv, respectively. CONCLUSION: TAG of CCTA provided high diagnostic accuracy for detecting haemodynamically significant coronary artery stenosis. TAG of stress CCTA was more diagnostically accurate, especially in coronary arteries with moderate stenosis. PMID- 29582879 TI - Short-term rehospitalisation or death and determinants after admission for acute heart failure in a cohort of African patients in Port Harcourt, southern Nigeria. AB - BACKGROUND: Heart failure (HF) is a major health burden globally and contributes significantly to morbidity and mortality related to cardiovascular disease. The aim of this study was to determine the outcome, and factors determining these outcomes in patients admitted for acute HF and followed up for six months. METHOD: This was a hospital-based, prospective study. Subjects included consecutive patients with a confirmed diagnosis of acute HF admitted to the medical wards of the University of Port Harcourt Teaching Hospital (UPTH) in Nigeria over one year. All had a full physical examination and relevant investigations, including echocardiography. Subjects were followed up for six months and reassessed for outcome/endpoint, which was rehospitalisation or death. Factors that predicted these outcomes were also determined. RESULTS: There were 160 subjects, 84 females and 76 males, age range 20 to 87 years, mean age 52.49 +/- 13.89 years. Sixteen subjects (10.0%) were lost to follow up, 66 (41.3%) showed clinical improvement, 57 (35.6%) were rehospitalised, while 21 (13.1%) died. Determinants of rehospitalisation were New York Heart Association (NYHA) class, heart failure type, haemoglobin level at presentation and estimated glomerular filtration rate (eGFR). Determinants of mortality were NYHA class and haemoglobin level at presentation. CONCLUSION: Heart failure rehospitalisation and mortality rates of 35.6 and 13.1%, respectively, were high compared to developed countries. PMID- 29582881 TI - Risk assessment of the occurrence of sudden death related to hypertrophic cardiomyopathy in Dakar. AB - AIM: The aim of this study was to assess of the risk of sudden death in a population of hypertrophic cardiomyopathy patients in Dakar. METHODS: This was a transverse study at the cardiology clinic of Aristide Le Dantec Hospital from January 2014 to June 2015. We used the European Society of Cardiology risk score to calculate this risk. RESULTS: The average age of patients was 53 years. Unexplained syncope was found in two patients and two others had a family history of sudden death. The septal hypertrophy average was 20.9 mm. Seven patients had left intraventricular obstruction. One patient had a high risk of sudden death, three had intermediate risk and 13 had low risk. Competitive sport was not allowed, 13 patients were under medical treatment, one had an implantable cardioverter defibrillator and two had no treatment. CONCLUSION: Our study highlighted a low and intermediate risk of the occurrence of sudden death at five years. One patient had a high risk of sudden death. PMID- 29582882 TI - Coronary artery bypass grafting and paraparesis; is there a correlation? AB - Adult cardiac surgery is associated with significant perioperative morbidity and mortality rates, mainly in elderly patients with co-morbidities. A series of postoperative complications may arise and delay the recovery of patients undergoing cardiac surgery. Such complications also increase the burden of resource use and may affect late survival rates. Neurological complications appear mainly as stroke of varying degrees, with impairment of mobility and ability of the patient. We describe a rare case of progressive paraparesis after on-pump coronary artery bypass grafting, and review its aetiology, diagnosis and management. PMID- 29582880 TI - Left ventricular remodelling in chronic primary mitral regurgitation: implications for medical therapy. AB - Surgical repair or replacement of the mitral valve is currently the only recommended therapy for severe primary mitral regurgitation. The chronic elevation of wall stress caused by the resulting volume overload leads to structural remodelling of the muscular, vascular and extracellular matrix components of the myocardium. These changes are initially compensatory but in the long term have detrimental effects, which ultimately result in heart failure. Understanding the changes that occur in the myocardium due to volume overload at the molecular and cellular level may lead to medical interventions, which potentially could delay or prevent the adverse left ventricular remodelling associated with primary mitral regurgitation. The pathophysiological changes involved in left ventricular remodelling in response to chronic primary mitral regurgitation and the evidence for potential medical therapy, in particular beta adrenergic blockers, are the focus of this review. PMID- 29582883 TI - Editorial: Orthogeriatrics and Hip Fractures. PMID- 29582885 TI - Insulin Resistance is Associated with Chronic Laryngitis in Korean Women. AB - OBJECTIVES: The aim of this study was to investigate the association between chronic laryngitis (CL) and insulin resistance (IR) in South Korea using data from the 2010 Korea National Health and Nutrition Examination Surveys (KNHANES). DESIGN, SETTING AND PARTICIPANTS: Cross-sectional data of 4,261 adults who completed KNHANES were analyzed. CL was considered when participants experienced a voice change and demonstrated flexible laryngoscopic findings of diffuse laryngeal inflammation. All participants were assessed for IR using the homeostasis model assessment of insulin resistance (HOMA-IR). RESULTS: Among the Korean population older than 19 years, the prevalence of chronic laryngitis was 3.8+/-0.7%. Univariate analysis demonstrated that CL was significantly associated with smoking and systolic and diastolic blood pressure in men and with age, diastolic blood pressure, HDL cholesterol, insulin, and HOMA-IR in women. Multiple regression analysis demonstrated that the mean value of HOMA-IR was significantly associated with CL in women only. In addition, CL was more prevalent in the highest compared with the lowest HOMA-IR quartile (OR [95% CI]: 2.268 [1.053-4.884] after adjusting for age, OR [95% CI]: 2.235 [1.040-6.181] after adjusting for confounding factors of age, body mass index, smoking status, alcohol intake, regular exercise, education, and income). CONCLUSIONS: These findings indicate that IR characterized by HOMA-IR is significantly associated with CL in Korean women only. Our results suggest that HOMA-IR could be an early predictive factor of increased risk of CL in Korean women. PMID- 29582884 TI - Involvement of Advanced Practice Nurse in the Management of Geriatric Conditions: Examples from Different Countries. AB - The increasing demand for healthcare services is placing great strain on healthcare systems throughout the world. Although the older population is increasing worldwide, there is a marked deficit in the number of persons trained in geriatrics. It is now recognized that early detection and treatment of geriatric conditions (e.g., frailty, sarcopenia, falls, anorexia of aging, and cognitive decline) will delay or avert the development of disability. At the same time, recent years have seen an increased interest and use of advanced practice nurses (APN). Models of best practices of supervision and collaboration have been promulgated by many organizations. APN's roles and scope of practice have been expanded in many countries and the quality and cost-effectiveness of healthcare systems have improved. Nevertheless, in older people, evidence of advanced practice roles remains scattered, and there is little synthesis of evidence, and therefore it is not easy to visualize the different practice models and their components. The aim of this paper is to explain the need for advanced practice nurses to manage geriatric conditions. PMID- 29582886 TI - Smoking Predicting Physical Activity in an Aging America. AB - OBJECTIVES: Tobacco smoking and physical inactivity are among leading behavioral risk factors for ill health in older adults. This study considers how smoking is associated with physical activity. DESIGN: Using a Life-Course model, data are analyzed regarding this relationship, controlling for, and interacted with, life course and other factors. Daily smokers and sometimes smokers were hypothesized to engage in less leisure-time physical activity than those who never smoked, while those who stopped smoking were expected to do more than never smokers. Analyses were performed using SAS-Callable SUDAAN. SETTING AND PARTICIPANTS: Secondary data from ten years of a national sample of adults aged 18 and over of the National Health Interview Survey, 2001-2010, are used (N = 264,945, missing data excluded, of 282,313 total cases). MEASUREMENTS: Daily smokers, occasional smokers, and smoking quitters are compared to never smokers with regard to requisite physical activity (150 minutes per week of moderate, 100 of vigorous, and/or 50 of strengthening activity). Life-course measures include birth cohorts, age, and year of survey, as well as gender, race/ethnicity, and education. RESULTS: Overall, hypotheses are supported regarding daily smokers and quitters; but the hypothesis is strongly rejected among sometimes smokers, who are much more likely to do requisite physical activity. Findings differ by age, sometimes smokers age 65 and over being less likely to do physical activity. Findings among all men are similar to the overall findings, while those among all women are similar to those for older respondents. Associations of smoking status with physical activity vary greatly by race/ethnicity. CONCLUSIONS: Daily smokers may be most in need of both smoking cessation and leisure-time physical activity interventions. Smoking-cessation efforts may pay greater physical activity benefits among women and the aged, while smoking-reduction efforts may provide better outcomes among men. Smoking reduction efforts may pay more exercise benefits among African-Americans and Hispanics. PMID- 29582887 TI - Cardiorespiratory Adaptations in Elderly Men Following Different Concurrent Training Regimes. AB - BACKGROUND: This study aimed to investigate the effects of different intra session exercise orders during concurrent training (CT) on endurance performance in elderly men, as well as to verify its influence on individual responses in endurance performance. DESIGN: Twenty-five healthy elderly men (64.7 +/- 4.1 years) were placed into two groups: strength training prior to endurance training (SE, n=13), and one in the reverse order (ES, n=12). CT was performed three times a week during 12 weeks. Before and after training, peak oxygen uptake (VO2peak), maximal workload (Wmax), absolute and relative cycling economy at 25, 50, 75 and 100 W (i.e., average VO2 at different stages) were assessed. RESULTS: Similar increases in VO2peak were observed in the SE and ES groups (SE: 8.1 +/- 9.9%; ES: 9.3 +/- 9.8%; P<0.001), as well as in Wmax (SE: 19.9 +/- 19.3%; ES: 24.1 +/- 24.0%; P<0.001). Moreover, significant reductions were observed in the absolute VO2 at 100 W (P<0.05) in the SE and ES groups. No difference between groups was observed. In the ES group, one subject did not respond positively in terms of both VO2max and Wmax, whereas 4 subjects did not respond positively in terms of both VO2max and Wmax in SE group. CONCLUSIONS: CT improved maximal and submaximal endurance performance in elderly men, independent of intra-session exercise order. However, it seems that the ES order elicited more individual responsiveness in terms of maximal endurance performance than SE order. PMID- 29582888 TI - Intake of 25-Hydroxyvitamin D3 Reduces Duration and Severity of Upper Respiratory Tract Infection: A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Comparison Study. AB - OBJECTIVES: This study aimed to assess the effect of 25-hydroxyvitamin D3 (25OHD) which is a hydroxide of vitamin D3 ingestion on upper respiratory tract infection (URTI). DESIGN AND SETTING: A prospective, randomized, double-blind, placebo controlled study was performed from December 2015 to September 2016 in the Nihonbashi Egawa Clinic, Kei Medical Office TOC Building Medical Clinic, and Medical Corporation Kaiseikai Kita-Shinyokohama Medical Clinic, in Japan. PARTICIPANTS: Four hundred twenty eight participants aged 45-74 years were screened by their serum 25-hydoroxyvitamin D concentration. INTERVENTION: The participants were randomized to either 25OHD (10 MUg/day) or placebo capsule, daily, for 16 consecutive weeks. MEASUREMENTS: The primary outcome measure was the incidence proportion of URTI, and the secondary outcome measures were the physical severity score, the quality-of-life (QOL) score, the duration of URTI, and the incidence proportion of new URTI events every four weeks. Data were collected using cold diary Wisconsin Upper Respiratory Symptom Survey-21 (WURSS 21) during the intervention. RESULTS: Of 428 participants screened, 252 with serum 25-hydroxyvitamn D levels were deficient or insufficient (75 nmol/L or less) were enrolled in this study. Of these, 105 placebo and 110 25OHD group subjects completed the study. For the incidence proportion of URTI, no effect of 25OHD intake was observed. On the other hand, the duration of URTI was shorter in the 25OHD (P = 0.061) compared to placebo. For the incidence proportion of URTI every four weeks, the incidence of new URTI was decreased in both groups over the time of intake. However, when the 25OHD and the placebo were compared, a decrease in the incidence proportion of URTI was seen earlier in the 25OHD. When the total physical severity score and the total QOL score during the study were assessed, they both were significantly improved in the 25OHD compared to placebo. CONCLUSIONS: The intake of 25OHD may reduce the duration of URTI, the physical severity, and the QOL when suffering from URTI. PMID- 29582889 TI - Muscle Weakness and Physical Disability in Older Americans: Longitudinal Findings from the U.S. Health and Retirement Study. AB - IMPORTANCE: Muscle weakness is an important indicator of disability, chronic disease and mortality. While we recently proposed sex/race specific grip strength cutpoints for clinical muscle weakness in a diverse, nationally representative sample of older Americans, the extent to which these cutpoints predict physical disability remains unknown. OBJECTIVE: To examine whether sex/race specific muscle weakness cutpoints predict physical disability status in a nationally representative sample of Americans age 65+. DESIGN: We used data from the 2006 2010 Health and Retirement Study. Fully-adjusted, weighted multinomial logistic regression models were used to quantify the odds of experiencing the onset, progression or persistence of disability in activities of daily living (ADL) among weak versus non-weak individuals over a 2-year period. SETTING: General community, nationally representative sample of older Americans. PARTICIPANTS: Population-based, community dwelling sample of older American adults aged 65 years+; 57 percent were women, 91% were White and the mean age was 75 years. Main Outcome(s) and Measure(s): The primary outcome of interest was disability dynamics, defined by changes in ADL status across at 2- year period. The primary exposure was clinical muscle weakness as defined by previously identified cutpoints. Hypotheses were formulated before analyses were conducted. RESULTS: In this nationally representative sample (n= 8,725), 44% of individuals were classified as weak at baseline. At follow-up, 55% remained independent with no change in their ADL status, 11% had an onset of disability and 4% progressed in their disability status. The odds of experiencing an onset of ADL disability was 54% higher among weak individuals compared those who were not weak at baseline (OR= 1.54, 95% CI= 1.54, 1.5, p<.0001); the odds of experiencing a progression in physical disability status was 2.16 times higher among those who were weak at baseline compared to non-weak individuals (OR= 2.16, 95% CI= 2.15, 2.16, p<.0001). CONCLUSIONS: This is the first study to use grip strength weakness cut points to identify those who may be at greatest risk for experiencing physical disability in later life. Results underscore the importance of using population specific cutpoints for clinical weakness in order to identify individuals at greatest risk for adverse health outcomes. PMID- 29582890 TI - Association between Serum Uric Acid Level and Carotid Atherosclerosis in Chinese Individuals Aged 75 Years or Older: A Hospital-Based Case-Control Study. AB - OBJECTIVES: To investigate the association between serum uric acid level and the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older. DESIGN: Case-control study. SETTING: In a teaching hospital. PARTICIPANTS: Five hundred and sixty-four elderlies (75 years or above) who underwent general health screening in our hospital were enrolled. MEASUREMENTS: The detailed carotid ultrasound results, physical examination information, medical history, and laboratory test results including serum uric acid level were recorded, these data were used to analyze the relationship between serum uric acid level and carotid atherosclerosis. Then, subjects who underwent the second carotid ultrasound 1.5-2 years later were further identified to analyzed the relationship between serum uric acid and the progression of carotid atherosclerosis. RESULTS: A total of 564 subjects were included, carotid plaque was found in 482 (85.5%) individuals. Logistic regression showed that subjects with elevated serum uric acid (expressed per 1 standard deviation change) had significantly higher incidence of carotid plaque (odds ratio, 1.37; 95% confidence interval, 1.07-1.75; P= 0.012) after controlling for other factors. A total of 236 subjects underwent the follow-up carotid ultrasound. Linear regression showed that serum uric acid level (expressed per 1 standard deviation change; 1 standard deviation = 95.5 MUmol/L) was significantly associated with percentage of change of plaque score (P = 0.008). Multivariable linear regression showed that 1 standard deviation increase in serum uric acid levels was expected to increase 0.448% of plaque score (P = 0.023). CONCLUSION: The elevated serum uric acid level may be independently and significantly associated with the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older. PMID- 29582891 TI - Age and IQ Explained Working Memory Performance in a RCT with Fatty Fish in a Group of Forensic Inpatients. AB - OBJECTIVES: To investigate the effect of a long-term fatty fish intervention on a pure cognitive mechanism important for self-regulation and mental health, i.e. working memory (WM), controlling for age and IQ. DESIGN: A randomized controlled trial. SETTING: A forensic facility. PARTICIPANTS: Eighty-four young to middle aged male forensic inpatients with psychiatric disorders. INTERVENTION: Consumption of farmed salmon or control meal (meat) three times a week during 23 weeks. MEASUREMENT: Performance on WM tasks, both accuracy and mean reaction time, were recorded pre and post intervention. RESULTS: Performance on a cognitive functioning tasks taxing WM seemed to be explained by age and IQ. CONCLUSION: Fatty fish consumption did not improve WM performance in a group of young to middle aged adults with mental health problems, as less impressionable factors such as aging and intelligence seemed to be the key components. The present study improves the knowledge concerning the interaction among nutrition, health and the aging process. PMID- 29582892 TI - Frequency of Hospital Use Before and After Home-Delivery Meal by Meals On Wheels, of Tarrant County, Texas. AB - BACKGROUND: Patients recently discharged from the hospital are vulnerable and are at high risk for readmission. Home-delivered meals may be beneficial in improving their health and facilitating independent living in the community. The purpose of this study was to identify the association between home-delivered meals and use of hospital services. METHODS: This study includes 120 clients recently discharged from an inpatient hospital stay or from an emergency department (ED) visit who received meal services from Meals On Wheels, Inc., of Tarrant County. Healthcare utilization data was extracted from the Dallas-Fort Worth Hospital Council Foundation, a regional all claims database used by over 90% of hospitals in Dallas-Fort Worth area. Signed tests and generalized linear models (GLM) were performed. RESULTS: A total of 16,959 meals were delivered from March 2013 through March 2014. Each client received an average of 6.19 meals per week. The average number of ED visits decreased from 5.03 before receipt of meals to 1.45 after receipt of meals, z = -5.23, p < .001. The average number of hospitalizations decreased from 1.33 to .83, z = -7.29, p < .001. The average length of stay per hospitalization decreased from 5.47 days to 2.34 days, z = 5.84, p < .001. Clients who received more meals were less likely to experience ED visits and hospitalizations after controlling for demographic characteristics and levels of physical functioning. CONCLUSION: The findings of this study indicate that home-delivered meals services may contribute to a reduction in hospital based care services among frail and vulnerable adults. Additional studies should consider the short and long-term effects of home-delivered meals services on healthcare utilization and the potential to decrease healthcare costs. PMID- 29582893 TI - Fat Quality Index and Risk of Cardiovascular Disease in the Sun Project. AB - OBJECTIVES: To examine the association between a dietary fat quality index (FQI), and the risk of incident cardiovascular events or deaths in the Seguimiento Universidad de Navarra (SUN) cohort. DESIGN: Longitudinal analysis during 10.1 years of median follow-up. Cox models were used to estimate adjusted hazard ratios (HR) of incident cardiovascular diseases (CVD) according to tertiles of FQI and of different fat subtypes. SETTING: University of Navarra, Spain. PARTICIPANTS: 19,341 middle-aged adults. MEASUREMENTS: Fat intake was measured with a validated food-frequency questionnaire. The FQI was calculated according to the ratio: (monounsaturated+polyunsaturated) / (saturated+trans fatty acids). RESULTS: We observed 140 incident cases of CVD. No association was found for FQI (HR=0.94, 95 %CI 0.61-1.47 for the highest vs the lowest tertile, p for trend=0.884). No significant associations were found for different dietary fat subtypes on CVD risk. The results suggest no clear association between a higher FQI and a higher amount of energy from fat and incidence of CVD (p for interaction: 0.259 and p for trend only among participants with a percentage of energy from fat >=35% of total energy: 0.272). CONCLUSION: In this Mediterranean cohort, the FQI was not associated with cardiovascular events. A "heart-healthy diet" should focus its attention on dietary fat sources and should use an overall dietary pattern approach, rather than limiting the focus on fat subtypes. More research is needed to validate dietary advice on specific fatty acids intake or saturated fatty acids replacements for reducing CVD risk. PMID- 29582894 TI - Sex Differences in the Associations between L-Arginine Pathway Metabolites, Skeletal Muscle Mass and Function, and their Responses to Resistance Exercise, in Old Age. AB - OBJECTIVES: The current study was designed to explore the associations between L arginine metabolites and muscle mass and function in old age, which are largely unknown. DESIGN: The study used a randomised, double-blind, placebo-controlled design. SETTING: The study was carried out in a laboratory setting. PARTICIPANTS: 50 healthy older adults [median age 70 years (IQR 67-73); 27 males]. INTERVENTION: Participants undertook an 18-week resistance exercise program, and a nutritional intervention (fish oil vs. placebo). MEASUREMENTS: Serum homoarginine, ornithine, citrulline, asymmetric dimethylarginine (ADMA), NG monomethyl-L-arginine (L-NMMA), and symmetric dimethylarginine (SDMA), maximal voluntary contraction (MVC) and isokinetic torque of the knee extensors at 30 degrees s-1 (MIT), muscle cross sectional area (MCSA) and quality (MQ) were measured at baseline and after the intervention. RESULTS: No significant exercise induced changes were observed in metabolite concentrations. There were significant sex differences in the associations between metabolites and muscle parameters. After adjusting for age, glomerular filtration rate and fish oil intervention, citrulline (P=0.002) and ornithine (P=0.022) were negatively associated with MCSA at baseline in males but not females. However, baseline citrulline was negatively correlated with exercise-induced changes in MVC (P=0.043) and MQ (P=0.026) amongst females. Furthermore, amongst males, baseline homoarginine was positively associated with exercise-induced changes in MVC (P=0.026), ADMA was negatively associated with changes in MIT (P=0.026), L-NMMA (p=0.048) and ornithine (P<0.001) were both positively associated with changes in MCSA, and ornithine was negatively associated with changes in MQ (P=0.039). CONCLUSION: Therefore, barring citrulline, there are significant sex differences in the associations between L-arginine metabolites and muscle mass and function in healthy older adults. These metabolites might enhance sarcopenia risk stratification, and the success of exercise programs, in old age. PMID- 29582895 TI - "Feeling More Self-Confident, Cheerful and Safe". Experiences from a Health Promoting Intervention in Community Dwelling Older Adults - A Qualitative Study. AB - OBJECTIVES: Studies show that regular exercise in combination with nutritional support can be effective in managing sarcopenia, which is age-related involuntary loss of skeletal muscle mass and strength. Qualitative investigations of participants' experiences from interventions in this domain are scarce. In this study, we explored older persons' experiences from an intervention designed to prevent sarcopenia, with the aim of capturing the participants' thoughts and opinions. DESIGN: A qualitative study embedded in the multicenter randomized clinical trial The Vitality and Vigor in the Elderly study, VIVE2. Focus group interviews were conducted. Manifest and latent content analyses were performed. PARTICIPANTS: Community dwelling older adults (n=20) 71-86 years of age with minor limitations in mobility. RESULTS: The experiences from the intervention were categorized and interpreted in one overall theme "Feeling more self confident, cheerful and safe". The theme encompasses the categories psychological effects of participating in the intervention, physical effects of participating in the intervention, the importance of social support and the importance of a tailored set-up. The participants described their motives for participating in the intervention as being based on concerns regarding the negative health effects of continuing a sedentary lifestyle, difficulties of getting started on their own and lack of confidence in accomplishing change on their own. Participants also expressed that one main objective for participating was to lose weight. CONCLUSION: In this study we have captured the experiences of older adults with minor mobility limitations who participated in a lifestyle intervention. The experiences are interpreted in one overall theme "Feeling more self-confident, cheerful and safe". The central understanding of the participants' experiences was that the intervention affected them in several ways, both psychologically and physically, and that supporting factors included the social support, which became a prerequisite for success. A noticeable finding was the discrepancy between the motive of the participants, to lose weight, and the aim of the study, to improve muscle function. The expectation to lose weight seems to reflect what is commonly known as to be healthy. To our knowledge, at least in Sweden, there are no campaigns or public information highlighting the risks of sarcopenia and the complex issue of if, and when weight loss is desirable for older individuals. This finding highlights the importance of providing such information to this target group. The findings in this study provide valuable knowledge for research teams, practitioners and decision makers when designing and setting objectives for health-promoting interventions for older individuals. PMID- 29582896 TI - Cognitive Dysfunction in Urban-Community Dwelling Prefrail Older Subjects. AB - OBJECTIVES: A number of studies have reported that frailty is cross-sectionally associated with cognitive decline and is also a risk for future cognitive decline or dementia; however, there have been only a few studies that focus on the association between prefrailty and cognitive dysfunction. In the current study, we investigated the association between prefrailty and cognition. DESIGN: A cross sectional study of the data obtained at registration in a randomized control trial. SETTING: Toyota, Japan. PARTICIPANTS: Community-dwelling older subjects (male 54.6%) who had cognitive complaints. MEASUREMENTS: A battery of neuropsychological and physical assessments were performed. Prefrailty was defined as exhibiting one or two of the five Fried criteria (weight loss, exhaustion, weakness, slow gait speed and low physical activity). We performed a multiple regression analysis to investigate the associations of cognitive performance with prefrailty, adjusting for the factors that were significantly different between the robust and prefrailty groups. To assess the cognitive attributes that were significantly associated with prefrailty, logistic analysis was performed to see if one specific criterion of the five frailty criteria was associated with cognitive performance. RESULTS: The study subjects included 183 prefrail and 264 robust individuals. The prefrail subjects with cognitive complaints were older, less educated, more depressive, and more likely to have diabetes mellitus than the robust subjects. The prefrail subjects had lower performance in a wide-range of cognitive domains, and after adjustments for age, education, depressive mood, and diabetes mellitus, prefrailty was associated with a decline in delayed memory and processing speed. Among the components of the Fried criteria, slow gait speed and loss of activity were significantly associated with slow processing speed as assessed by the digit symbol substitution test. CONCLUSION: The current results demonstrated that prefrailty was associated with worse memory and processing speed performance, but not with other cognitive domains. PMID- 29582897 TI - Dietary Restriction Ameliorates Age-Related Increase in DNA Damage, Senescence and Inflammation in Mouse Adipose Tissuey. AB - : Ageing is associated with redistribution of fat around the body and saturation of visceral adipose depots. Likewise, the presence of excess fat in obesity or during ageing places extra stress on visceral depots, resulting in chronic inflammation and increased senescence. This process can contribute to the establishment of the metabolic syndrome and accelerated ageing. Dietary restriction (DR) is known to alleviate physiological signs of inflammation, ageing and senescence in various tissues including adipose tissue. OBJECTIVES: Our pilot study aimed to analyse senescence and inflammation parameters in mouse visceral fat tissue during ageing and by short term, late-onset dietary restriction as a nutritional intervention. Design, measurements: In this study we used visceral adipose tissue from mice between 5 and 30 months of age and analysed markers of senescence (adipocyte size, gammaH2A.X, p16, p21) and inflammation (e.g. IL-6, TNFalpha, IL-1beta, macrophage infiltration) using immuno-staining, as well as qPCR for gene expression analysis. Fat tissues from 3 mice per group were analysed. RESULTS: We found that the amount of gammaH2A.X foci as well as the expression of senescence and inflammation markers increased during ageing but decreased with short term DR. In contrast, the increase in amounts of single or aggregated macrophages in fat depots occurred only at higher ages. Surprisingly, we also found that adipocyte size as well as some senescence parameters decreased at very high age (30 months). CONCLUSIONS: Our results demonstrate increased senescence and inflammation during ageing in mouse visceral fat while DR was able to ameliorate several of these parameters as well as increased adipocyte size at 17.5 months of age. This highlights the health benefits of a decreased nutritional intake over a relatively short period of time at middle age. PMID- 29582898 TI - 8-Methoxypsoralen Plus Ultraviolet A Reduces the Psoriatic Response to Imiquimod in a Murine Model. AB - The effects of 8-Methoxypsoralen plus ultraviolet A (PUVA) or ultraviolet B (UVB) alone on imiquimod-induced psoriasis were examined in a mouse model. Mouse skin was treated with repetitive sub-phototoxic doses of PUVA or UVB before or during the induction of toll-like receptor 7/8 activation and psoriasis through the application of imiquimod. PUVA, to a greater degree than UVB, suppressed the established imiquimod-induced psoriatic phenotype, but pretreatment with PUVA prior to administration of imiquimod also reduced the susceptibility of murine skin to respond to imiquimod to a greater degree than did pretreatment with UVB. PUVA downregulated baseline levels of miRNA27a and 29a, as well as interferon gamma, interleukin-17 and -9, cytokines, which drive psoriatic inflammation. Microarray analysis showed enrichment of senescence pathway genes linked to upregulation of p16/p21 proteins after PUVA pretreatment. However, the anti psoriatic effect of PUVA was lost when there was an interval of 7 days between final exposure to PUVA and the start of administration of imiquimod. This indicated that (UVB and) PUVA diminished imiquimod-induced established psoriatic inflammation, but also primed the skin in favour of a reduced responsiveness to toll-like receptor activation.

AB - OBJECTIVE: To assess the efficiency of knee-ankle-foot orthoses for treating painful genu recurvatum, and to determine users' tolerance and satisfaction. PATIENTS: Patients included in the study had a genu recurvatum during the stance phase, confirmed by a medical doctor on physical examination. A total of 27 patients with 31 knee-ankle-foot orthoses were included. METHODS: The main outcome was scored on a verbal numerical rating scale (VNRS) before and at least 3 months after a knee-ankle-foot orthosis was fitted, and scored on a verbal numerical pain rating scale (VRS). Secondary outcomes were rated with the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST). RESULTS: After fitting the knee-ankle-foot orthosis, the median VNRS pain score decreased from 85/100 to 25/100 (p <= 0.001) and the description of pain on the VRS decreased from "extreme" to "mild" (p <= 0.001). The QUEST total score was 4.0. CONCLUSION: Treating a painful genu recurvatum with a knee-ankle-foot orthosis reduced the pain efficiently whatever the patients' diagnosis, and high scores were obtained for patients' satisfaction. PMID- 29582900 TI - Developing a spinal cord injury rehabilitation service in Madagascar. AB - Rehabilitation for people with spinal cord injury in many low- and middle-income countries is not avail-able or is in the early stages of development. However, rehabilitation is recognized as crucial in order to optimize functional recovery and outcomes for patients with spinal cord injury. With an increasing incidence of spinal cord injury, the unmet need for rehabilitation is huge. This report describes the early development of a specialist rehabilitation service for spinal cord injury in Madagascar, one of the poorest countries in the world. The sustained input to an expanding rehabilitation team has led to reductions in avoidable complications. The input of the rehabilitation team has been welcomed by the neurosurgery department, which has recognized fewer delays in patients undergoing surgical treatments. Cost, lack of resources and trained staff, and poor understanding of disability continue to provide challenges. However, the development of the rehabilitation service using low technology, but with a high level of knowledge and systematic management, is a source of considerable pride. This development in Madagascar can be regarded as a model for spinal cord injury rehabilitation in other low-resource settings. PMID- 29582901 TI - Dimensionality and scaling properties of the Patient Categorisation Tool in patients with complex rehabilitation needs following acquired brain injury. AB - OBJECTIVE: To investigate the scaling properties of the Patient Categorisation Tool (PCAT) as an instrument to measure complexity of rehabilitation needs. DESIGN: Psychometric analysis in a multicentre cohort from the UK national clinical database. PATIENTS: A total of 8,222 patents admitted for specialist inpatient rehabilitation following acquired brain injury. METHODS: Dimensionality was explored using principal components analysis with Varimax rotation, followed by Rasch analysis on a random sample of n = 500. RESULTS: Principal components analysis identified 3 components explaining 50% of variance. The partial credit Rasch model was applied for the 17-item PCAT scale using a "super-items" methodology based on the principal components analysis results. Two out of 5 initially created super-items displayed signs of local dependency, which significantly affected the estimates. They were combined into a single super-item resulting in satisfactory model fit and unidimensionality. Differential item functioning (DIF) of 2 super-items was addressed by splitting between age groups (<65 and >= 65 years) to produce the best model fit (chi2/df = 54.72, p = 0.235) and reliability (Person Separation Index (PSI) = 0.79). Ordinal-to-interval conversion tables were produced. CONCLUSION: The PCAT has satisfied expectations of the unidimensional Rasch model in the current sample after minor modifications, and demonstrated acceptable reliability for individual assessment of rehabilitation complexity.

AB - Due to the lack of evidence-based guidelines, management strategies for neonatal MI should be individualized and administered largely at the discretion of responsible treating teams. Supportive care with a focus on preserving adequate circulation and antithrombotic therapy with a view to restoring vascular patency are the mainstays of treatment. Thrombolytic therapy of neonatal MI includes a chance to completely restore myocardial function. Understanding the resilience of the neonatal heart and mechanism of cardiac cell repair in neonates may spark novel treatment strategies for severe MI in the large number of affected individuals in an aging population.

AB - : The haemophilia treatment centre of the Clinic for Children and Youth Medicine in Jena extends medical care by health-promotion measures, namely: health counselling, adjuvant exercise therapy and school sports. In addition to the regular medical checks at the treatment centre patients are examined regarding physical fitness, joint situation, quality of life in general and disease specific manner, as well as psycho-social and nutritional behaviour. Findings and medical results of the examinations are integrated into an individual advice on therapy, school sports, and health recommendations. This aimed at strengthening health-related resources and minimizing potential injuries. First long-term evaluation shows an increase of activity behaviour and physical fitness without increasing bleeding rate and maintained joint function. CONCLUSION: Combining functional prevention diagnostics and individual health counselling shows signs of improved patient's health knowledge, self-competence and physical fitness. PMID- 29582908 TI - Wishes and worries of haemophilia patients. AB - Haemophilia care in Germany has achieved a high level and enables the majority of patients to lead a largely normal life. The Bluter Betreuung Bayern e.V. (BBB) aims to improve health care and support for haemophilia patients. A questionnaire has been developed by BBB representatives to evaluate unmet medical needs from the patient perspective. It was sent to 290 haemophilia patients and/or their parents in Bavaria in November 2015. The response rate was 51.4 %: 66 children aged < 15 years (66.7 % severe), 30 patients 15-24 years (66.7 % severe), 26 patients 25-44 years (80.8 % severe), 24 patients > 44 years (95.8 % severe). Prophylactic therapy in patients with severe haemophilia aged < 25 and >= 25 years is given "always" in >= 80 % and > 60 %, respectively. Substitution therapy is mostly uncomplicated. Satisfaction with medical care is high. Chronic pain is a problem with increasing age. Patients aged 25-44 years worry least regarding future health, safety and availability of factor products, patients > 44 years most. Overall, 80-100 % of the patients from all age groups are interested in information on the current state of science. Offers of the BBB for psychosocial support in addition to the medical care seem to be helpful and needed in all age groups. PMID- 29582909 TI - Portuguese Haemophilia Registry. AB - National Patient Registries (NPR) have an important role in the management of haemophilia and other inherited bleeding disorders, representing powerful instruments to support healthcare and research. Computer software to assist the NPR is crucial, as it facilitates the introduction of the data from a national universe that will be centralized and merged into a unique location, thus ensuring a greater reliability and accuracy of the collected data, avoiding duplication of patients. In Portugal, despite the efforts and recognition of the need of a NPR, just recently the protocol for the establishment of the computer software to support the Portuguese National Registry of Haemophilia and other Congenital Coagulopathies (PorR H&CC) was approved. This paper aims to present this newly developed computerized solution, as well as to report the main variables and information that will be available. The development of this application, which includes a set of sociodemographic, clinical and treatment data, was based on the principles of WFH, and the database that supports the NPR, with anonymized data, is operated and maintained in accordance with the Data Protection Law. Currently, the first data are available on the application. Our focus now is to ensure more registries and continuous data entry in order to have complete information on the characterization of the haemophilia patient population in Portugal. PMID- 29582910 TI - Subchondral haematoma. AB - : Haemophilic arthropathy is a complex multifactorial disorder that poses significant challenges to both the treating haematologist and arthroplasty surgeon. Its pathogenesis is incompletely understood. Recent literature has concentrated on the toxic effects of iron and the characteristic inflammatory synovitis. Discussion of the role of subchondral bleeding in joint damage has been neglected. A case of haemophilic arthropathy with extensive evidence of subchondral bleeding and related osteochondral destruction is presented. RESULT: The relevance of this mechanical pathway in the future management of haemophilic arthropathy is discussed with reference to recent literature. CONCLUSION: Clinicians should consider its importance when deciding whether to manage patients expectantly or with prophylactic factor replacement. PMID- 29582911 TI - One Year with Methods Open.

A Replicated Single-Subject Design AB - BACKGROUND: Depressive disorders often have a chronic course and the efficacy of evidence-based treatments may be overestimated. OBJECTIVE: To examine the effectiveness of the Heart Rate Variability Stress Reduction Program (SRP) as a supplement to standard treatment in patients with depressive disorders. METHODS: The SRP was individually administered in eight weekly sessions. Seven participants completed the full protocol and were enrolled in a single-subject ABA multiple baseline experimental design. To perform interrupted time-series analyses, daily measures were completed in a diary (depression, resilience, happiness, heart coherence and a personalized outcome measure). RESULTS: Five out of seven patients improved in depressed mood and/or a personalized outcome measure. The effect of treatment was reversed in four patients during the withdrawal phase. One patient reliably improved on depression, whereas two patients recovered on autonomy and one on social optimism. No consistent relationship was found between the heart rate variability-related level of coherence and self-reported mood levels. CONCLUSIONS: The SRP is beneficial in some domains and for some patients. A prolonged treatment or continued home practice may be required for enduring effects. The intervention had more clinical impact on resilience-related outcome measures than on symptoms. The small sample size does not permit generalization of the results. We recommend future investigation of the underlying mechanisms of the SRP. PMID- 29582915 TI - Use of an Activity Tracker to Test for a Possible Correlation of Resting Heart Rate with Life Events. An N-of-1 Study of Participant-provided Data PMID- 29582914 TI - Are Nomothetic or Ideographic Approaches Superior in Predicting Daily Exercise Behaviors? AB - OBJECTIVES: The understanding of how stress influences health behavior can provide insights into developing healthy lifestyle interventions. This understanding is traditionally attained through observational studies that examine associations at a population level. This nomothetic approach, however, is fundamentally limited by the fact that the environment- person milieu that constitutes stress exposure and experience can vary substantially between individuals, and the modifiable elements of these exposures and experiences are individual-specific. With recent advances in smartphone and sensing technologies, it is now possible to conduct idiographic assessment in users' own environment, leveraging the full-range observations of actions and experiences that result in differential response to naturally occurring events. The aim of this paper is to explore the hypothesis that an ideographic N-of-1 model can better capture an individual's stress- behavior pathway (or the lack thereof) and provide useful person-specific predictors of exercise behavior. METHODS: This paper used the data collected in an observational study in 79 participants who were followed for up to a 1-year period, wherein their physical activity was continuously and objectively monitored by actigraphy and their stress experience was recorded via ecological momentary assessment on a mobile app. In addition, our analyses considered exogenous and environmental variables retrieved from public archive such as day in a week, daylight time, temperature and precipitation. Leveraging the multiple data sources, we developed prediction algorithms for exercise behavior using random forest and classification tree techniques using a nomothetic approach and an N-of-1 approach. The two approaches were compared based on classification errors in predicting personalized exercise behavior. RESULTS: Eight factors were selected by random forest for the nomothetic decision model, which was used to predict whether a participant would exercise on a particular day. The predictors included previous exercise behavior, emotional factors (e.g., midday stress), external factors such as weather (e.g., temperature), and self-determination factors (e.g., expectation of exercise). The nomothetic model yielded an average classification error of 36%. The ideographic N-of-1 models used on average about two predictors for each individual, and had an average classification error of 25%, which represented an improvement of 11 percentage points. CONCLUSIONS: Compared to the traditional one-size-fits-all, nomothetic model that generalizes population-evidence for individuals, the proposed N-of-1 model can better capture the individual difference in their stressbehavior pathways. In this paper, we demonstrate it is feasible to perform personalized exercise behavior prediction, mainly made possible by mobile health technology and machine learning analytics.

AB - BACKGROUND: In the estimation of physiological kinetic parameters from Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) data, the determination of the arterial input function (AIF) plays a key role. OBJECTIVES: This paper proposes a Bayesian method to estimate the physiological parameters of DCE-MRI along with the AIF in situations, where no measurement of the AIF is available. METHODS: In the proposed algorithm, the maximum entropy method (MEM) is combined with the maximum a posterior approach (MAP). To this end, MEM is used to specify a prior probability distribution of the unknown AIF. The ability of this method to estimate the AIF is validated using the Kullback-Leibler divergence. Subsequently, the kinetic parameters can be estimated with MAP. The proposed algorithm is evaluated with a data set from a breast cancer MRI study. RESULTS: The application shows that the AIF can reliably be determined from the DCE-MRI data using MEM. Kinetic parameters can be estimated subsequently. CONCLUSIONS: The maximum entropy method is a powerful tool to reconstructing images from many types of data. This method is useful for generating the probability distribution based on given information. The proposed method gives an alternative way to assess the input function from the existing data. The proposed method allows a good fit of the data and therefore a better estimation of the kinetic parameters. In the end, this allows for a more reliable use of DCE-MRI. PMID- 29582919 TI - A cross-sectional analysis of joint status and quality of life in children and adolescents with haemophilia in Romania. AB - BACKGROUND: Haemophilia is a congenital disorder of coagulation with high economic burden due to its requirement for an expensive, lifelong replacement therapy, with additional costs for the frequent complications and for the severe handicapping consequences. The objective of this cross-sectional study aimed at giving an insight into the health condition of young haemophiliacs in the absence of a regular prophylactic therapy. METHODS: It was conducted on a heterogeneous group of 37 children and adolescents (4-24 years of age), with similar on demand therapeutic regimen, coming from the whole country, focusing on the joint status by using the Haemophila Joint Health Score (HJHS) system and on quality of life (QoL) by using the EQ-5D-3L-Y questionnaire. RESULTS: The results revealed an impressive situation: 70.3 % with chronic arthropathy, 19 % with target joints, 69 % with multiple joint involvement, mainly elbow (41 %) and knee (34 %), joint damage starting in the age group 6-12 years (18.18 % arthropathy vs. 96 % in the age group above 12 years). Joint score (6.67 +/- 7.92), gait score (0.75 +/- 1.14) and HJHS (7.43 +/- 8.78) were highly correlated (r = 0.7, p = 0.001) with the annualised bleeding rate ABR (16.2 +/- 12.1). They impacted the QoL in all domains, also expressed by a VAS of 68.39 +/- 21.6. CONCLUSION: We concluded that in the situation of an international consensus that prophylactic replacement can prevent cost-effectively and cost-efficiently the deleterious joint damages, our study is supporting the introduction even of secondary and tertiary prophylaxis in young patients in our country. PMID- 29582920 TI - Follow-up of a 6-month Programmed Sports Therapy (PST) in patients with haemophilia. AB - Studies describe benefits of exercise in Patients with haemophilia (PwH), but research on training sustainability is rare. Aim of this study was to observe the follow-up of a guided 6-month training intervention in PwH. This study included 28 PwH after a training intervention (RCT) over 6 months. N=17 continued training (TC), N=11 stopped training (TS) after the study time. Strength measurements and subjective physical performance were tested.The RCT revealed that all muscles tested increased significantly after training. In the follow-up phase, the muscles of TC increased further (in TS decreased), but not all of them significantly (M. triceps brachii: p=0.017; M. biceps brachii: n.s.; M. latissimus dorsi: n.s.; M. rectus abdominis: p=0.002; M. biceps femoris right: n.s.; left: p=0.028; M. quadriceps femoris both n.s. = not sig.). Subjective performance showed no clear changes in the follow-up phase.This is the first study evaluating a follow-up phase of programmed sports therapy (PST) in PwH. PST (6-month) resulted in some PwH continuing the successful training. Benefits were training routine, safety and partially further positive training effects, e.g. in strength performance. PMID- 29582921 TI - The role of ultralarge multimers in recombinant human von Willebrand factor - a review of physico-and biochemical studies and findings in in vivo models and in humans with von Willebrand disease. AB - Ultralarge multimers (ULM) of VWF are considered to be the most active with respect to binding to platelets and to subendothelial structures and therefore are of critical importance for the function of VWF in stabilizing the primary hemostatic plug. In contrast to plasma-derived FVIII-VWF concentrates, human rVWF obtained from mammalian cell culture retains the full-spectrum of intact multimers, including ULM, as physiologically formed in the Golgi apparatus and stored in platelet alpha-granules and endothelial cell Weibel-Palade bodies. In the course of physico and biochemical, functional and animal studies, rVWF exhibited superiority in structure and function compared to pdVWF. These effects seemed to correlate with the multimer size and therefore might be attributed to the presence of ULM in rVWF preparations. The pharmacokinetic (PK), safety and efficacy characteristics seen in preclinical studies were further demonstrated in clinical trials. PMID- 29582922 TI - A rare case of unprovoked venous thromboembolism manifestation in a young patient with antithrombin Type IIB deficiency combined with inferior vena cava anomaly from Lithuania. AB - : Hereditary antithrombin (AT) deficiency is an autosomal-dominant disorder predisposing to venous and arterial thrombosis. Homozygosity resulting in severe AT deficiency is not compatible with life, apart from homozygous mutations affecting the heparin-binding site representing the most severe thrombophilia. PATIENTS AND METHODS: A 12-year-old previously healthy boy of Romani origin presented with a swollen, painful left leg and fever. Imaging revealed signs of inferior vena cava (IVC) thrombosis, the presence of interrupted intrahepatic IVC with azygos continuation and bilateral iliofemoral thrombosis with enlargement of the azygous and hemiazygos venous system. In addition, right pleural effusion and signs of bilateral renal pericortical cysts, possibly caused by retroperitoneal lymphangiectasia, were disclosed. Thrombophilia screening involving protein C, Protein S, Antithrombin (chromogenic assays based on the inhibition of FIIa and FXa, antigen concentration), APC resistance, prothrombin mutation and Lupus anticoagulants was performed using standard laboratory methods. Genetic analysis of the SERPINC1 gene was done by direct sequencing. RESULTS: Thrombophilia screening showed isolated decreased AT activity at 21% (RR 80-120%). AT levels were retested and remained decreased (33-36%) on two consecutive occasions. SERPINC1 gene analysis revealed a previously described homozygous mutation (Budapest III) causing type IIB deficiency (c.391C>T; p.Leu131Phe). A family study confirmed the same mutation in both parents and three siblings. The patient improved significantly following warfarin therapy and over the past 2.5 years did not experience new thromboembolism. CONCLUSIONS: This case represents a rare combination of two risk factors provoking manifestation of spontaneous venous thromboembolism at a young age requiring permanent anticoagulant therapy. PMID- 29582923 TI - [Rapid Report Hemophilia - Evidence in treatment of hemophilia from the IQWiG's perspective]. AB - : The German Institute for Quality and Efficiency in Health Care (IQWiG) conducted a rapid report to assess the therapy of hemophilia patients. Based on a systematic literature search the IQWiG identified 16 studies which show that there is now sufficient information regarding questions that previously lacked data. A benefit assessment of prophylactic and on-demand-treatment concerning different treatment outcomes shows the superiority of the prophylactic therapy regarding major bleedings for all age groups. For the group of youths and adults the analysis shows additional benefits concerning health status and pain within the preceding four weeks. The alignment of guidelines with the identified evidence shows minor correspondence between the guidelines' references and included studies. However, the guidelines' statements primarily correspond with the results of the conducted benefit assessment. CONCLUSION: The IQWiG's rapid report shows prophylactic therapy to be superior to on-demand therapy. These findings represent a clear indication for attending physicians and payers for prophylaxis in patients with severe hemophilia A.

PMID- 29582926 TI - ? PMID- 29582927 TI - Direct oral anticoagulants for the treatment of cancer-associated venous thromboembolism. AB - Cancer patients with venous thromboembolism (VTE) are at increased risk for both bleeding and VTE recurrence. Anticoagulation with low-molecular-weight heparin (LMWH) is the standard of care during the initial and longterm treatment phase (i.e. during the first 3 - 6 months of therapy) based on its overall beneficial safety and efficacy profile compared to vitamin K antagonists (VKAs). The direct oral anticoagulants (DOACs) rivaroxaban, apixaban, edoxaban, and dabigatran are approved for the treatment of acute VTE, and the combined six phase-3 trials have included > 1500 patients with active cancer, as defined by variable selection criteria. Subgroup analyses of these patients, either pooled or separately reported, suggest that DOACs could be a safe and efficacious alternative to VKA therapy for the treatment of cancer-associated VTE. However, the populations of cancer patients included in the DOAC and LMWH trials are not comparable with regard to mortality and VTE risk, and no specific data from direct head-to-head comparisons of DOACs with LMWHs are currently available. The use of DOACs for the management of VTE in cancer is thus not recommended by clinical practice guidelines. PMID- 29582928 TI - Direct oral anticoagulants (DOAC) - Management of emergency situations. AB - The worldwide increase in the aging population and the associated increase in the prevalence of atrial fibrillation and venous thromboembolism as well as the widespread use of direct oral anticoagulants (DOAC) have resulted in an increase of the need for the management of bleeding complications and emergency operations in frail, elderly patients, in clinical practice. When severe bleeding occurs, general assessment should include evaluation of the bleeding site, onset and severity of bleeding, renal function, and concurrent medications with focus on anti-platelet drugs and nonsteroidal anti-inflammatory drugs (NSAID). The last intake of the DOAC and its residual concentration are also relevant. The site of bleeding should be immediately localized, anticoagulation should be interrupted, and local measures to stop bleeding should be taken. In life-threatening bleeding or emergency operations immediate reversal of the antithrombotic effect may be indicated. If relevant residual DOAC-concentrations are expected and surgery cannot be postponed, prothrombin complex concentrate (PCC) and/or a specific antidote should be given. While idarucizumab, the specific antidote for dabigatran, has been recently approved for clinical use, the recombinant factor X protein andexanet alfa, an antidote for the reversal of inhibitors of coagulation factor Xa, and ciraparantag, a universal antidote, are not available. Future cohort studies are necessary to assess the efficacy and safety of specific and unspecific reversal agents in "real-life" conditions. This was the rationale for introducing the RADOA-registry (RADOA: Reversal Agent use in patients treated with Direct Oral Anticoagulants or vitamin K antagonists), a prospective non interventional registry, which will evaluate the effects of specific and unspecific reversal agents in patients with life-threatening bleeding or emergency operations either treated with DOACs or vitamin K antagonists. PMID- 29582929 TI - Update on Direct Oral AntiCoagulants (DOACs). AB - Recent findings require an update of previous recommendations for the perioperative use of Direct Oral AntiCoagulants (DOACs). A break in preoperative treatment of 24-96 hours is recommended based on the pharmacokinetic profiles of DOACs and depends on individual patient characteristics, their renal and possibly liver function, and their surgery-related risk of bleeding. In cases of renal or hepatic insufficiency, whether to extend the preoperative interruption of IIa- and Xa-inhibitors is a clinical decision that must be reached on an individual patient basis. In cases of epidural or spinal anaesthesia, more conservative pausing-intervals are recommended due to the risk of persistent neurologic deficits (e.g., paraplegia) following the development of spinal subdural and epidural haematomas. Elective surgery should be postponed according to these recommendations. Preoperative "bridging" with LMWH (more precisely referred to as "switching") should be omitted due to a significantly increased risk of bleeding. In addition, the incidence of perioperative thromboembolic risks, such as DVT, PE, and stroke, are no different whether interruption or "switching" is undertaken. Postoperatively, the DOACs can be reinstituted within the first 24 hours. In cases of major surgery or if there is a higher risk of bleeding, resumption of DOACS should only begin after 24-72 hours. In patients with an elevated thromboembolic risk, transient postoperative LMWH administration can be recommended during this period.Interaction of DOACs with other drugs usually occurs during the absorption, transport and elimination of these drugs. Therefore, substance- specific restrictions and recommendations should be observed during these times. In everyday clinical practice, webbased, independent information portals on drug-interactions are very helpful in providing safe and rapid information about potential interactions when DOACs are used in combination with other drugs, especially during perioperative management.Non-adherence to medications is a worldwide problem that has dangerous and costly consequences. Present data suggest that persistence is the primary factor that supports adherence. Despite the adherence data presented in the DOACS approval studies (e.g., persistence in the treatment of acute venous thromboembolism has been reported to be between 94-99%), the first registries and meta-analyses provide sobering results regarding the incidence of persistence and the success rate of interventions designed to improve adherence with DOACs in cases of long-term usage. PMID- 29582930 TI - DOAC use in patients with chronic kidney disease. AB - Direct oral anticoagulants (DOACs) are increasingly prescribed substances in patients with indication for effective anticoagulation. Patients with chronic kidney disease (CKD) have a high burden of cardiovascular risk and are more likely to develop atrial fibrillation (AF) than patients without CKD. Patients with mild to moderate CKD benefit from DOACs, especially when having intolerance to vitamin K-antagonists (VKA). DOACs may in some cases be considered in patients with rare renal disease and hypercoagulabilic state. DOACs are to a large extent eliminated by renal excretion. Since prospective randomised data in CKD patients are sparse, the decision for anticoagulative therapy is challenging especially in patients with severe renal impairment. The direct factor Xa-inhibitors are approved for use even in patients with an estimated glomerular filtration rate (eGFR) between 15 and 30 ml/min. Careful monitoring of renal function on a regular basis is essential before initiation and after start of DOAC, especially for patients at risk for acute renal failure (elderly, diabetics, patients with preexisting kidney disease). None of the DOACs is approved in CKD patients with end-stage-renal-disease (ESRD) with or without dialysis. DOACs are not recommended for kidney transplant patients under immunosuppression with calcineurin inhibitors. In these patients conventional therapy with VKA is the only option, which has to be monitored closely since it has potential adverse effects.

PMID- 29582932 TI - Development and Usability of a Smartphone Application for Tracking Antiretroviral Medication Refill Data for Human Immunodeficiency Virus. AB - BACKGROUND: Adherence to antiretroviral medication leads to HIV suppression and decreased morbidity and mortality. In resource- limited settings, the dependence on paper medical charts and unstable electronic health records creates a challenge to monitoring medication adherence. A pharmacy-based strategy that utilizes existing cellular phone infrastructure may lead to a more stable system to monitor adherence. OBJECTIVES: To develop and evaluate the usability of a smartphone-based software application (app) for tracking antiretroviral medication refill data in a resource-limited setting. METHODS: A pharmacy-based smartphone app for tracking HIV medication adherence was developed through a multi-step rapid prototyping process. The usability of the app was assessed during the daily activities of pharmacy dispensers at HIV clinics in and around Gaborone, Botswana using a validated computer usability survey. RESULTS: The study demonstrated the effective development of and favorable end-user responses to a pharmacy-based HIV medication adherence app. End users had suggestions for minor changes to improve the app's functionality. CONCLUSIONS: In resource limited settings where electronic health record support is limited, such a system was feasible and appealing. In the future, this system may allow for improved HIV medication adherence tracking and be applied to medications beyond antiretrovirals. PMID- 29582934 TI - Mining Major Transitions of Chronic Conditions in Patients with Multiple Chronic Conditions. AB - OBJECTIVES: Evolution of multiple chronic conditions (MCC) follows a complex stochastic process, influenced by several factors including the inter relationship of existing conditions, and patient-level risk factors. Nearly 20% of citizens aged 18 years and older are burdened with two or more (multiple) chronic conditions (MCC). Treatment for people living with MCC currently accounts for an estimated 66% of the Nation's healthcare costs. However, it is still not known precisely how MCC emerge and accumulate among individuals or in the general population. This study investigates major patterns of MCC transitions in a diverse population of patients and identifies the risk factors affecting the transition process. METHODS: A Latent regression Markov clustering (LRMCL) algorithm is proposed to identify major transitions of four MCC that include hypertension (HTN), depression, Post- Traumatic Stress Disorder (PTSD), and back pain. A cohort of 601,805 individuals randomly selected from the population of Iraq and Afghanistan war Veterans (IAVs) who received VA care during three or more years between 2002-2015, is used for training the proposed LRMCL algorithm. RESULTS: Two major clusters of MCC transition patterns with 78% and 22% probability of membership respectively were identified. The primary cluster demonstrated the possibility of improvement when the number of MCC is small and an increase in probability of MCC accumulation as the number of co- morbidities increased. The second cluster showed stability (no change) of MCC overtime as the major pattern. Age was the most significant risk factor associated with the most probable cluster for each IAV. CONCLUSIONS: These findings suggest that our proposed LRMCL algorithm can be used to describe and understand MCC transitions, which may ultimately allow healthcare systems to support optimal clinical decision- making. This method will be used to describe a broader range of MCC transitions in this and non-VA populations, and will add treatment information to see if models including treatments and MCC emergence can be used to support clinical decision-making in patient care. PMID- 29582935 TI - The Charlson Comorbidity Index in Registry-based Research. AB - BACKGROUND: Comorbidities may have an important impact on survival, and comorbidity scores are often implemented in studies assessing prognosis. The Charlson Comorbidity index is most widely used, yet several adaptations have been published, all using slightly different conversions of the International Classification of Diseases (ICD) coding. OBJECTIVE: To evaluate which coding should be used to assess and quantify comorbidity for the Charlson Comorbidity Index for registry-based research, in particular if older ICD versions will be used. METHODS: A systematic literature search was used to identify adaptations and modifications of the ICD-coding of the Charlson Comorbidity Index for general purpose in adults, published in English. Back-translation to ICD version 8 and version 9 was conducted by means of the ICD-code converter of Statistics Sweden. RESULTS: In total, 16 studies were identified reporting ICD-adaptations of the Charlson Comorbidity Index. The Royal College of Surgeons in the United Kingdom combined 5 versions into an adapted and updated version which appeared appropriate for research purposes. Their ICD-10 codes were back-translated into ICD-9 and ICD-8 according to their proposed adaptations, and verified with previous versions of the Charlson Comorbidity Index. CONCLUSION: Many versions of the Charlson Comorbidity Index are used in parallel, so clear reporting of the version, exact ICD- coding and weighting is necessary to obtain transparency and reproducibility in research. Yet, the version of the Royal College of Surgeons is up-to-date and easy-to-use, and therefore an acceptable co-morbidity score to be used in registry-based research especially for surgical patients. PMID- 29582936 TI - Addressing the Data Linking Challenges. AB - BACKGROUND: PARENT JA (cross-border Patient Registries iNiTiative Joint Action), a joint EU and Member States project, has conducted a research among EU patient registries aimed at gathering information on the registries' interoperability readiness. Leaning on the information and data collected through the previous PARENT JA research, this study aims to provide more detailed view into the registry holders' practical challenges with data linking. Since the studies which dealt with patient data exchange have often neglected the registry holders' performance of data exchange, we wanted to put a spotlight on various EU registry holders' practices and operations, aiming to detect their needs and concerns in the process of running an interoperable registry. The focus of this study was identifying the main practices and challenges in patient registries interoperability improvement. METHODS: The basis for this analysis were the data collected in the series of structured interviews. The size of the interview sample was 13 patient registries, each from a different EU country. The structured interview consisted of nine questions and was conducted in two parts: oral and written. The answers were analysed using open coding. RESULTS: Results are interpreted in the context of the six main themes that emerged through a comprehensive analysis. (1) Examples of data exchange: The most common reported data exchange practices were seen only as a way to achieve the most immediate needs and interests of the individual registries. (2) Awareness and use of international standards: International data and clinical standards were not widely used by the interviewed registries. (3) Use of data models and formats: In the area of data models and formats there is no universally used practice. (4) Data request protocols and procedures: Procedures and protocols varied, mostly depending on the national legal systems in which the patient registries operated. (5) Data security and integrity: Security of personal data was a universal concern for all registry holders that were interviewed; identifiable individual data was shared only in one case. (6) Opportunities and challenges of registry interoperability: most registry holders responded that their registries were well prepared for interoperability practices and that data exchange has never been their primary operative concern. CONCLUSIONS: Most of the difficulties regarding data linking were not necessarily associated with technical issues, which registry holders listed outright. Our analysis showed that the lack of interoperability came as a result of organizational or legal constraints that made the registries unable to process and conduct data linking quickly and effectively with other sources.

PMID- 29582938 TI - [Taste dysfunction (dysgeusia) and radioiodine therapy of thyroid cancer - Be aware of side effects by antidepressants and sedatives]. AB - In addition to xerostomia, taste dysfunction (hypo-, dysgeusia) is an independent side effect of radioiodine therapy of thyroid cancer. Hypogeusia results from damage of the small mucous salivary glands in the vicinity of the taste buds. Particularly in those patients, who are treated with drugs such as antidepressants or sedatives, taste dysfunction becomes frequently clinically symptomatic. If feasible, therapy regimens bearing a potential risk for taste dysfunction should be switched. Additional damage to taste function should be minimalized, including cessation of smoking, change of agents for dental hygiene, and change of toothpaste. If the medical indication for ablative radioiodine therapy is based on the patient's decision, the patient should be informed about alternative strategies. Potential clinical consequences of the sialadenitis (xerostomia, alter ation in taste, risk of caries and tooth extraction, lacrimal gland dysfunction, tearing and need of dacryocystorhinostomy) should be revealed completely. Adapted to the initial risk of relapse, the131 I-activity for ablation should be reduced to the latest standard of care. Clinical data are currently too heterogeneous to decide whether rhTSH might reduce the rate of dysgeusia. The specialist in nuclear medicine should be aware of the multifactorial causes of taste dysfunction, in particular if the patient seeks medical advice after radioiodine therapy. PMID- 29582940 TI - Closed-system drug-transfer devices plus safe handling of hazardous drugs versus safe handling alone for reducing exposure to infusional hazardous drugs in healthcare staff. AB - BACKGROUND: Occupational exposure to hazardous drugs can decrease fertility and result in miscarriages, stillbirths, and cancers in healthcare staff. Several recommended practices aim to reduce this exposure, including protective clothing, gloves, and biological safety cabinets ('safe handling'). There is significant uncertainty as to whether using closed-system drug-transfer devices (CSTD) in addition to safe handling decreases the contamination and risk of staff exposure to infusional hazardous drugs compared to safe handling alone. OBJECTIVES: To assess the effects of closed-system drug-transfer of infusional hazardous drugs plus safe handling versus safe handling alone for reducing staff exposure to infusional hazardous drugs and risk of staff contamination. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, OSH-UPDATE, CINAHL, Science Citation Index Expanded, economic evaluation databases, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov to October 2017. SELECTION CRITERIA: We included comparative studies of any study design (irrespective of language, blinding, or publication status) that compared CSTD plus safe handling versus safe handling alone for infusional hazardous drugs. DATA COLLECTION AND ANALYSIS: Two review authors independently identified trials and extracted data. We calculated the risk ratio (RR) and mean difference (MD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models. We assessed risk of bias according to the risk of bias in non-randomised studies of interventions (ROBINS-I) tool, used an intracluster correlation coefficient of 0.10, and we assessed the quality of the evidence using GRADE. MAIN RESULTS: We included 23 observational cluster studies (358 hospitals) in this review. We did not find any randomised controlled trials or formal economic evaluations. In 21 studies, the people who used the intervention (CSTD plus safe handling) and control (safe handling alone) were pharmacists or pharmacy technicians; in the other two studies, the people who used the intervention and control were nurses, pharmacists, or pharmacy technicians. The CSTD used in the studies were PhaSeal (13 studies), Tevadaptor (1 study), SpikeSwan (1 study), PhaSeal and Tevadaptor (1 study), varied (5 studies), and not stated (2 studies). The studies' descriptions of the control groups were varied. Twenty-one studies provide data on one or more outcomes for this systematic review. All the studies are at serious risk of bias. The quality of evidence is very low for all the outcomes.There is no evidence of differences in the proportion of people with positive urine tests for exposure between the CSTD and control groups for cyclophosphamide alone (RR 0.83, 95% CI 0.46 to 1.52; I2 = 12%; 2 studies; 2 hospitals; 20 participants; CSTD: 76.1% versus control: 91.7%); cyclophosphamide or ifosfamide (RR 0.09, 95% CI 0.00 to 2.79; 1 study; 1 hospital; 14 participants; CSTD: 6.4% versus control: 71.4%); and cyclophosphamide, ifosfamide, or gemcitabine (RR not estimable; 1 study; 1 hospital; 36 participants; 0% in both groups).There is no evidence of a difference in the proportion of surface samples contaminated in the pharmacy areas or patient-care areas for any of the drugs except 5-fluorouracil, which was lower in the CSTD group than in the control (RR 0.65, 95% CI 0.43 to 0.97; 3 studies, 106 hospitals, 1008 samples; CSTD: 9% versus control: 13.9%).The amount of cyclophosphamide was lower in pharmacy areas in the CSTD group than in the control group (MD -49.34 pg/cm2, 95% CI -84.11 to -14.56, I2 = 0%, 7 studies; 282 hospitals, 1793 surface samples). Additionally, one interrupted time-series study (3 hospitals; 342 samples) demonstrated a change in the slope between pre-CSTD and CSTD (3.9439 pg/cm2, 95% CI 1.2303 to 6.6576; P = 0.010), but not between CSTD and post-CSTD withdrawal (-1.9331 pg/cm2, 95% CI -5.1260 to 1.2598; P = 0.20). There is no evidence of difference in the amount of the other drugs between CSTD and control groups in the pharmacy areas or patient-care areas.None of the studies report on atmospheric contamination, blood tests, or other measures of exposure to infusional hazardous drugs such as urine mutagenicity, chromosomal aberrations, sister chromatid exchanges, or micronuclei induction.None of the studies report short-term health benefits such as reduction in skin rashes, medium-term reproductive health benefits such as fertility and parity, or long-term health benefits related to the development of any type of cancer or adverse events.Five studies (six hospitals) report the potential cost savings through the use of CSTD. The studies used different methods of calculating the costs, and the results were not reported in a format that could be pooled via meta-analysis. There is significant variability between the studies in terms of whether CSTD resulted in cost savings (the point estimates of the average potential cost savings ranged from (2017) USD -642,656 to (2017) USD 221,818). AUTHORS' CONCLUSIONS: There is currently no evidence to support or refute the routine use of closed-system drug transfer devices in addition to safe handling of infusional hazardous drugs, as there is no evidence of differences in exposure or financial benefits between CSTD plus safe handling versus safe handling alone (very low-quality evidence). None of the studies report health benefits.Well-designed multicentre randomised controlled trials may be feasible depending upon the proportion of people with exposure. The next best study design is interrupted time-series. This design is likely to provide a better estimate than uncontrolled before-after studies or cross-sectional studies. Future studies may involve other alternate ways of reducing exposure in addition to safe handling as one intervention group in a multi-arm parallel design or factorial design trial. Future studies should have designs that decrease the risk of bias and enable measurement of direct health benefits in addition to exposure. Studies using exposure should be tested for a relevant selection of hazardous drugs used in the hospital to provide an estimate of the exposure and health benefits of using CSTD. Steps should be undertaken to ensure that there are no other differences between CSTD and control groups, so that one can obtain a reasonable estimate of the health benefits of using CSTD.

AB - INTRODUCTION: Hadassah-Hebrew University Medical Center is regaining its lead in Israeli public medicine with clinical excellence, state-of-the art technology, high achievement in research, and outstanding medical education for students and trainees. Hadassah has two campuses at Ein Kerem and Mount Scopus that together offer 1200-hospital beds and 40 hybrid and advanced operating rooms. Hadassah Medical Center, an initiative of Hadassah organization led by Henrietta Szold, is one of the foremost health care providers in Israel. Together, the Hebrew University and Hadassah are home to Schools of Medicine, Pharmacy, Nursing, Public Health, Occupational Therapy, and Dental Medicine. The medical school enrolls over 1000 medical students including a special track for military physicians. Hadassah opened the new Davidson medical tower in 2012 and the development of new infrastructure continues for Centers of Excellence in Surgery, Oncology, Hematology, and Medicine, for the benefit of the public in greater Jerusalem and all of Israel. In this journal, we will present 12 articles that represent the integration of state-of-the-art clinical medicine and research technologies, all dedicated to advancing medicine for the people of Israel. PMID- 29582942 TI - [FLUOROSCOPIC BASED NAVIGATION IN ORTHOPAEDIC TRAUMA - A REVIEW OF A LARGE CENTER'S EXPERIENCE]. AB - INTRODUCTION: Computer Assisted Orthopaedic Surgery (CAOS) was introduced in the late 1990's and early 2000's. Since then its application in orthopaedic trauma has been utilized mainly as augmented fluoroscopy for intraoperative navigation. From 2010 our center implemented an advanced system allowing further expansion of this technology. AIMS: The aim of this study was to describe the experience with an advanced fluoroscopic based CAOS system in our center. METHODS: The BrainLabTM Trauma 3.0 utilizes a handheld fluoroscope tracker, enables tracking of two anatomical objects and intraoperative planning. We implemented this system for the performance of 126 navigated procedures between the years 2011-2014. The procedures included 58 cases of navigated hip fracture pinning, 9 plate navigation for distal femoral fractures, 19 iliosacral screw insertions, 20 femoral fracture reductions, and 12 other procedures (acetabular screws, osteotomies etc). RESULTS: The mean age of patients was 52 years (range 16-82 years); 46 male and 80 female patients. The mean operating room time was 157 minutes (range 70 to 470 minutes). The average radiation required was 550 rad cm2 (~30 sec fluoroscopic time). Overall estimated additional OR time was estimated as 10-15 minutes for hip pinning, 15-20 minutes for pelvic iliosacral screws and 30-45 minutes of additional OR time for femur fracture reduction for length and rotation. In 5% of cases (6 patients), navigation was aborted due to technical reasons. No misplaced hardware due to the use of navigation was documented. CONCLUSIONS: CAOS is a powerful tool in trauma surgery with 95% success rate, with a reasonable added burden time. Although 3D navigation may be more useful in the pelvis, even two-dimensional navigation increases precision and implant placement. Femoral fracture reduction for accurate length and rotation control is solely enabled by CAOS. In the future, more time efficient and user-friendly systems will enable widespread use of these technologies in orthopaedic trauma.

AB - INTRODUCTION: Retinoblastoma (RB) is a malignant tumor presenting in the eyes of infants and children, which endangers life, the eye and vision. The treatment of RB has undergone marked changes in recent years, and great progress has been made in our ability to preserve eyes. Over the last three decades most Israeli patients with RB have been treated in the National Specialty Ocular Oncology Service at the Hadassah-Hebrew University Medical Center in Jerusalem. AIMS: To describe advances in the primary treatment of RB with an emphasis on eye preserving treatments. METHODS: The study included a retrospective cohort of patients who were diagnosed and treated at our center over the last three decades. Review of patients' records was approved by the Hadassah IRB. RESULTS: From 1988 to 2014 we diagnosed 290 children (138 girls - 47.6%). The mean age at diagnosis (+/-SE) was 18.1+/-1.2 months, median 12.5 months. RB was unilateral in 55.6% of the cases, bilateral in 41.3% and unilateral multifocal in 3.1%. There was an even distribution of disease severity (IRB grouping). Since the advent of IV chemotherapy (IVC) there has been a decrease in the rate of eye enucleation from ~90% to ~30% of the children until the year 2000 with a stable rate thereafter. In the years 1990-2000 there was an increase followed by a decrease in the use of primary external beam radiotherapy (EBRT), and a parallel small increase in the use of brachytherapy from the mid '90s until today. The recently introduced novel treatments - intravitreal (IVitC) and intra-arterial chemotherapy (IAC) - were used as a complimentary treatment to IVC, and not yet as a single primary modality until 2014. CONCLUSIONS: IVC replaced the need to enucleate in most of the cases, but 30% of children still require a primary enucleation. DISCUSSION: IVC usually requires additive treatments (thermal cryotherapy, trans-pupillary thermotherapy - TTT, brachytherapy and/or local chemotherapy - IVitC and IAC) and with the use of multi-modal therapy many eyes can be preserved. In the period reported in the current manuscript, the use of IAC as a primary treatment approach was only used in isolated cases. In Summary, There have been significant advances in our ability to save eyes, and the field continues to progress. PMID- 29582944 TI - [PERCUTANEOUS TREATMENT OF SMALL RENAL TUMORS BY THERMAL ABLATION]. AB - INTRODUCTION: Kidney cancer accounts for approximately 2-3 % of all types of cancers. Renal tumors prevalence and especially the prevalence of small renal tumors, is on the rise. About half of the tumors currently diagnosed are smaller than 4 cm. Minimally invasive methods of radiofrequency ablation technology were recently developed for the treatment of small renal tumors and are characterized by reducing the surgical and anesthetic risk. The ablation is performed with a percutaneous approach guided by ultrasound, CT or MRI. We reviewed the results of this treatment. METHODS: A total of 75 patients with a mean age of 69.5 years (27 - 90) were treated using RF during the period 2007-2014. The average tumor diameter was 28.4 mm (11-58 mm); 40 tumors were exophytic and 30 were central. Monitoring protocol after treatment included imaging after 1, 3, 6, 12 months subsequent to treatment and later annually; median follow-up time was 21 months (1 - 97). RESULTS: Evidence of tumor recurrence was observed in 9 patients (11.4%); 8 were treated successfully by another RF session. Cases in which recurrence was observed were characterized by a tumor larger than 30 mm (5/9) and adjacent to renal cysts (3/9); 5 of the lesions were central (endophytic) (P=0.5). One patient died due to metastatic RCC and a metastatic disease developed in two additional patients who died of other causes. CONCLUSIONS: It is possible to destroy most of the small renal tumors by RF ablation. When the tumor size is up to 30 mm, a 94% long-term cure may be reached. In the event of renewed growth of the tumor, the treatment can be repeated with good results. In light of short-term experience, it is recommended to limit this treatment to older patients, with a short life expectancy or when anesthetic risks prohibit surgery. PMID- 29582945 TI - [SPONTANEOUS PARENCHYMAL INTRACRANIAL HEMORRHAGE - A DIAGNOSTIC CHALLENGE]. AB - INTRODUCTION: Non-traumatic intracranial hemorrhage (ICH) is a devastating event associated with a high rate of morbidity and mortality. Patient age, hemorrhage location, number of foci, and underlying diseases are important clues to the etiology. Non-contrast head CT, given its availability and high sensitivity in detecting blood products, is frequently the first tool to readily detect ICH; however, different types of hemorrhages may share a common appearance on CT and the optimal therapeutic approach varies depending on etiology. An additional diagnostic work-up is frequently indicated to make the final diagnosis and to assist in urgent patient management. CT- and MR angiography, and digital angiography can diagnose vascular anomalies, CT venography can reveal cerebral vein thrombosis, diffusion-weighted MRI (DWI) may show hemorrhagic transformation of an infarct, and susceptibility-weighted MRI (SWI) may detect hypertensive and amyloid angiopathy-related microbleeds. MR also has a major role in revealing underlying etiologies such as cavernoma, primary brain tumor or metastases. These imaging tools assist in determining the cause of ICH, and also in assessing the risk of deterioration. Prognostic factors such as size, location, mass effect, and detection of the "spot sign" all play an important role in foreseeing possible deterioration, thus allowing prompt intervention. This study will present cases of intraparenchymal hemorrhage from different etiologies in patients who presented to the Hadassah-Hebrew University Medical Center, with the goal of illustrating the role of imaging in patient management and decision making. PMID- 29582946 TI - [EFFECTS OF CANNABIS EXTRACT PREMEDICATION ON ANESTHETIC DEPTH]. AB - BACKGROUND: Cannabis is the most widely used illicit drug in the world, used by approximately 2.7-4.9% of the world's population, and 7.6-10.2% of Israel's adults. During the past few years, legal systems around the world have enacted large scale adoption of the legalization of both medical and recreational cannabis. Anesthetists should therefore be prepared to treat patients who used cannabis and are undergoing elective or emergency operations. However, the interactions between cannabinoids and general anesthetic agents and the possible implications for patient care are not yet fully understood. OBJECTIVES: The study aimed to examine how preoperative use of cannabis affects the anesthesia process, and whether this use requires special attention by the anesthesiologists during surgery. Hence, we examined the effect of preoperative administration of cannabis extract Sativex (nabiximols) on obtained BIS value relative to the concentration of anesthetic gases. METHODS: This study is a double-blind randomized controlled trial. Twenty-seven patients undergoing elective orthopedic surgery under general anesthesia were randomly allocated to one of the following regimes: high dose cannabis (6), low dose cannabis (8), active placebo (6) and placebo (7). The study drugs were administered as premedication 20 minutes before induction of general anesthesia in a double-blind fashion. Cannabis was administered in the form of nabiximols (Sativex(r)), which is a highly-standardized extract of cannabis plants containing known drug dosages. During the surgery, hemodynamic parameters were monitored, and the anesthesia depth was measured using a BIS monitor, which is based on brain activity analysis. RESULTS: We found a significant effect of treatment groups on bispectral index (BIS) after controlling for minimum alveolar concentration (MAC). The average BIS values, as measured during steady state anesthesia, were significantly higher in the high dose cannabis treatment group. CONCLUSIONS: This study provides the first evidence that cannabinoids may affect the BIS. We speculate that the cannabinoid induced increase in BIS may be the result of changes in EEG activity rather than an indication of a shallower anesthetic state. However, this hypothesis should be examined in further studies. The clinical importance of this study is that with patients who use cannabis adjacent to general anesthesia induction, one cannot rely on the BIS monitoring for the purpose of determining the patient sedative state. PMID- 29582947 TI - [LONG TERM FOLLOW-UP OF TRANSCATHETER SELF EXPANDABLE AORTIC VALVE IMPLANTATION]. AB - INTRODUCTION: Aortic stenosis is the most common significant valvular disease in the western world. These patients are treated operatively unless they are at high operative risk or inoperable. During the last decade an alternative approach has evolved - transcatheter aortic valve implantation (TAVI). This method was shown to be at least as effective and safe as the operative one. However, very little data exists on long term follow-up (5 years and above), especially regarding valve durability and patient survival. OBJECTIVES: To present a long term follow up on patients who underwent transcutaneous self-expandable aortic valve implantation in our department between the years 2008-2011. METHODS: In September 2008 the first CoreValve implantation was performed in Israel at Hadassah Medical Center. All records of patients who were transplanted between 9.2008 and 10.2011 were reviewed. The function of the valve early after the procedure was compared to its function at the end of the follow-up period. RESULTS: A total of 38 patients (out of 71) survived at least 54 months, of them, 19 have an echocardiography examination at the end of the follow-up period. In all patients the implanted valve was found to function well at the end of the follow-up period, without significant stenosis or paravalvular leak. In fact, in approximately half of these patients, the degree of paravalvular leak decreased during the follow-up period. DISCUSSION: On long term (5 years) follow-up of patients who were implanted with the self-expandable aortic valve (CoreValve), no deterioration of the valve was observed. In fact, in approximately half of the patients, a decrease in the severity of the paravalvular leak was demonstrated.

MC pregnancies share their blood systems due to communicating vessels over their single placenta and may develop specific complications: Twin-to-Twin transfusion syndrome (TTTS), Selective intrauterine growth restriction (sIUGR), Twin Anemia-Polycythemia Sequence (TAPS), Twin Reverse Arterial Perfusion Syndrome (TRAP) or anomalies in one. Half of complicated MC require intrauterine interventions. Severe CDH is linked to a high rate of neonatal death due to pulmonary hypoplasia. Fetoscopic tracheal occlusion (FETO) with a balloon improves postnatal outcome. AIMS: A fetal therapy center was established in the Hadassah Medical Centers, Jerusalem in 2011 for intrauterine interventions. We report our 5 years' experience. METHODS: This prospective cohort follows the outcome of MC pregnancies and cases of severe CDH which underwent therapeutic fetal procedures in Hadassah between the years 2011 16. RESULTS: Out of 114 procedures, 95 were in MC: 84 monochorionic diamniotic twins, 7 monochorionic monoamniotic twins, 2 dichorionic triamniotic triplets and 2 monochorionic triplets. We treated 65 TTTS cases with fetoscopy and laser ablation of communicating vessels. The survival rate of both twins was 58.5% and at least one survived in 81.5% of the cases. In 2nd/3rd trimesters selective termination of 15 cases the survival rate of the remaining twin was 87%. In 11 cases of TRAP sequence treated with laser ablation of the feeding vessel the survival of the remaining twin was 91%. In 19 fetoscopies in severe CDH, 12 were for balloon insertion and 7 for removal. Endotracheal balloon was successfully placed in 11 of 12 cases (10 left-sided, 1 right-sided CDH). Balloon removal was prenatally performed by elective fetoscopy (n=7) or by intrapartum urgent puncture. There were no intrauterine fetal deaths. In isolated left-sided CDH the survival was 57%, whereas none survived in non-isolated left-sided CDH and right sided CDH. CONCLUSIONS: In-utero procedures are safe for the mother and increase newborn survival in MC pregnancies, thus specialized clinics are life-saving. FETO is a therapeutic option for severe CDH. Our results meet similar achievements reported by other leading world centers. PMID- 29582949 TI - [NEUROPSYCHIATRY AND COMPUTATIONAL MEDICINE]. AB - INTRODUCTION: The classical model of medicine is based on, first, history taking, followed by physical examination, data analysis by the clinician and their further validation using biological tests. Based on this, the clinician may plan the medical treatment. In neuropsychiatry, this model is even more limited as physical examination is based mostly on a patient-doctor conversation, and biological or imaging tests are directed mostly to extract the structural basis for the clinical manifestations. The rapidly developing computational revolution have not yet significantly influenced this model. Nevertheless, various advancements in machine-learning, algorithms, computation, internet, hardware, sensors, image processing and more intend to change this process profoundly. In this article we will review this process of computational medicine and exemplify how it enables new approaches in the domains of pain and dementia.

AB - INTRODUCTION: Population health is a term encompassing "the health outcomes of a group of individuals, including the distribution of such outcomes within the group." Only recently have hospitals viewed themselves as focal points for promoting health in a community, involving themselves with population health. Hadassah Medical Organization (HMO), however, has been in the business of population health since its founding. Its early programs, promoting and delivering nutritional support, maternal-child health and other services to the Yishuv's inhabitants, showed that the HMO defined its community broadly. Hospital care came later. The HMO was established together with the Hebrew University Israel's first School of Public Health and Community Medicine in the 1960's, contributing >1200 Israeli alumni, and exposing thousands of medical students to population health. The School's founders developed Community-Oriented Primary Care, aimed at assessing and addressing health determinants and outcomes at the community level implemented in many centers worldwide. Reaching beyond Israel's borders, the School has trained a global public health workforce through its International Masters in Public Health with >820 graduates from 92 countries. HMO's researchers have made important contributions in the fields of epidemiology, health economics and policy and population health methodology as well as hospital and community quality of care. This article reviews HMO's contribution to population health at local, municipal, national and international levels. We will demonstrate the unique circumstances in Hadassah, Jerusalem and Israel which have enabled world-class research and training in population health, identifying important contributions to policy and service provision, as well as addressing future population health challenges.

There is a great un-met clinical need for developing new treatments that will induce regeneration of injured skeletal tissues in cases such as large bony defects caused by trauma or tumor resection, articular cartilage defects and torn or degenerate tendons and ligaments. Except for bone that can regenerate small defects, all other skeletal tissues do not hold the natural capability for regeneration after injury and rather form a less functional scar tissue. In order to induce tissue regeneration, it is now believed that three crucial elements must reach the injured zone: a) multipotent cells that can rapidly proliferate and differentiate to form the injured tissues, such as mesenchymal stem cells for skeletal tissues; b) extra-cellular matrix that will support the newly built tissues, and c) the correct molecular signals. Using diverse research tools and expertise, our department focused its research on basic, translational and clinical solutions for injured and degenerative skeletal tissues. In this review we will describe our different research directions, from in-vitro cell cultures and animal models studies to human clinical trials. PMID- 29582952 TI - [EXOME ANALYSIS - A GAME CHANGER IN PEDIATRICS]. AB - INTRODUCTION: Thirteen years after the completion of the human genome project, the determination of the genomic sequence of the coding parts of the DNA (the exones, hence the exome), has turned into a primary diagnostic tool in daily use in clinical practice. The Department of Genetics at Hadassah was the first in Israel to introduce exome analysis as a robust diagnostic tool into the pediatric departments. Till now 2600 exomes were analyzed at Hadassah, 850 of them in 2016 alone. Exome analysis is cheap and fast, enabling precise and non-invasive diagnosis for a vast array of genetic disorders and congenital malformations. The unique composition of the population which the hospital serves (marked by a high rate of consanguinity) enabled reaching diagnosis in 65% of the cases, twice the rate in medical centers worldwide. The results of this analysis enable genetic counseling to patients' families and prevention of serious disorders. Moreover, the results contribute to the understanding of the biological basis of newly identified disorders and in certain cases assist in the management of the patients. The major limitation of exome analysis is the multitude of identified variants which exist in any individual and which challenge our ability to pick the disease-causing variant. In the case of a disease-causing variant in a new gene, experimental proof is required to validate the causality of the variant; occasionally, an incidental finding with possible clinical significance is identified, raising serious ethical concerns. In this article, we will review the use of this technology through the experience of three pediatric departments at Hadassah. PMID- 29582953 TI - [TO BE A RESIDENT IN THE DEPARTMENT OF MEDICINE]. AB - INTRODUCTION: Sir William Osler is considered to be one of the fathers of modern medicine who pioneered the practice of bedside teaching of clinical medicine for medical students and residents. Osler was well known as a diagnostician and outstanding therapist with a humanized approach and rare didactic capabilities. Medical training at Hadassah is built on the central tenets of Osler's approach, incorporating the tremendous advances in science and medicine. Training for residents in Internal Medicine is designed to develop a broad base of medical and, if possible, scientific knowledge, as well as skills and competencies to deliver a high standard of patient care. In the past 7 years, 28 residents have undergone specialist training in Internal Medicine B. Among them, 71% were Israeli medical school graduates; 36% were women;18% were recent immigrants to Israel; 78% were Jewish. Among Jewish residents, 32% were religiously observant. Besides the usual assignments of the internal medicine ward, the medical staff of Internal Medicine B excelled in diagnosis of hard to diagnose diseases as described in eleven cases. The diagnosis in some of those cases was a result of listening to the patient, education on clinical reasoning and the use advanced diagnostic tools. The basic unit of the residency is the clinical mission with an emphasis on exposure to novel modalities such as the use of bedside ultra sound along with dealing with end-of-life dilemmas, the management of complex situations and development of communication and interpersonal skills needed to work with close relatives and families facing critical times. The medical training in the internal ward is not just the sum of arbitrary care of the hospitalized patients, but a well-structured plan with gradually increasing demands. Over the past 7 years, residents in Internal Medicine B have achieved successful passing grades of 38/38 on the first attempt oral and written board examinations, a record that attests to the quality of the trainees and the training process. Hadassah has a long history of providing state-of-the-art patient care, and training young physicians to maintain this high standard - but the education process necessitates longstanding efforts and continuous striving for excellence.

PMID- 29582957 TI - [Renal manifestation of Autosomal Dominant Polycystic Kidney Disease]. AB - Autosomal dominant polycystic kidney disease affects over 12 million people in the world and is the fourth cause of ESRD. It is the main monogenic kidney disease and causes the progressive formation of cysts leading to renal failure after a few decades. The main manifestations of the disease are observed even at a young age. The early sign of ADPKD is impaired urinary concentrating capacity, due to medullary alteration by cysts, and resistance to vasopressin. These anatomical alterations determine hyperfiltration, altered ammonium transport, nephrolithiasis, and, above all, hypertension even in pediatric age. Activation of the renin-angiotensin-aldosterone system has been shown responsible for the maintenance of high pressure values as well as the growth of cysts and renal fibrosis. Arterial hypertension would be responsible for ventricular hypertrophy. Many recent studies have confirmed the role of pressure control, especially if rigorous, in decreasing the progression of renal disease, and the use of ACE inhibitors seems to have higher efficacy than other antihypertensive drugs. The progression of renal disease is evidenced by the reduction of glomerular filtration which may be minimal in the early years, due to hyperfiltration, but, then, may even exceed 5 ml / min per year, especially when the total kidney volume (TKV) exceeds 1500 ml. In more rapid progression forms, ESRD may appear at about 55 years of age. The main risk factors are age, genetic mutation, familiarity with ESRD, macrohematuria episodes, and early onset hypertension. Some authors have proposed both genetic and clinical scores that can provide guidance on the probability of rapid progression. Other renal manifestations include kidney pain, nephrolithiasis, urinary tract infections and cyst hemorrhage. Renal cell carcinoma is a very rare event. PMID- 29582958 TI - [CKD-MBD in Peritoneal Dialysis]. AB - CKD-MBD is a systemic disorder of the mineral and bone metabolism as a result of CKD. The clinical relevance of this syndrome has led to the identification of the biochemical targets to be achieved in order to improve the outcome of the patient. However, in hemodialysis (HD) and peritoneal dialysis (DP) patients, these targets are not reached. Hyperphosphatemia is a predictor of cardiovascular and all-cause mortality. In DP the removal of phosphorus (P) occurs by diffusion and convection, with a contribution of ultrafiltration of about 11%. P clearance is time dependent, with differences between CAPD and APD and depending on membrane transport characteristics. Residual renal function plays a key role in the P balance. Calcium (Ca) clearance in PD depends on the calcium levels, calcium concentration in dialysate and ultrafiltration. Positive Ca balance brings to Adynamic Bone Disease. Several bone-derived substances, some of them with hormonal action, have shed new light on the bone- cardiac axis. The hormonal functions of bone are likely to be related to histological lesions that develop during chronic renal failure. Compared to the past, recent data show less obvious differences in bone histomorphometry parameters between HD patients and PD patients. However, in PD patients fewer fractures are reported, probably due to different bone quality. PMID- 29582959 TI - [A cause of acute renal dysfunction: a giant bladder diverticulum]. AB - We describe the case of a previously 77-year-old man who accessed in our Nephrology Unit for acute kidney injury (AKI) on chronic kidney disease (CKD), gastric discomfort and vague urinary symptoms with apparently preserved diuresis and suspected "ascites". Physical examination confirmed the presence of abdominal effusion, even though ultrasound abdominal examination revealed the presence of a giant diverticular urinary bladder with bilateral hydronephrosis. We discuss the diagnostic and therapeutic approach of these rare complications by briefly reviewing the technical aspects and the possible consequences. PMID- 29582960 TI - [Acute kidney injury and rhabdomyolysis after cocaine overdose: case report and literature review]. AB - Cocaine, a natural alkaloid derived from the coca plant, is one of the most commonly used illicit drugs. Cocaine abuse causes systemic adverse effects like stroke, myocardic infarction, arterial dissection, vascular thrombosis and rhabdomyolysis. Cocaine use is, also, associated with renal complications such as acute kidney injury, vasculitis, acute interstitial nephritis, chronic kidney disease, malignant hypertension with thrombotic microangiopathy. Acute kidney injury may or may be not associated to rhabdomyolysis. Rhabdomyolysis caused by cocaine abuse is multifactorial, involving tissue ischemia secondary to vasoconstriction and cellular damage caused by the drug. We report a 50-year-old man with history of chronic hepatitis C and substance abuse admitted to our unit with severe rhabdomyolysis and acute kidney failure after nasal insufflation of cocaine overdose. Renal function recovered after several treatments of dialysis. We conclude that cocaine adversely impacts kidney function ; in addition cocaine and rhabdomyolysis are the double danger for acute kidney injury. Medical management of cocaine toxicity requires a multisystem approach, with close monitoring cardiac, neurological and renal function. PMID- 29582961 TI - [Case of sialadenitis by iodinated contrast medium in a dialysis patient]. AB - Background: Sialadenitis by iodinated contrast medium (i.c.m) oriodine mumps (IM) is a rare and late benign manifestation that occurs independently of intravenous or endoarterial administration modality. If renal function is normal, i.c.m. does not reach salivary glands concentrations able to induce sialadenitis. However, a critical glomerular filtration reduction may lead to salivary ducts edema and glandular swelling after i.c.m. injection. We report a rare case report of IM in a patient on chronic hemodialysis. Methods: A 72-year-old woman affected by chronic kidney disease on chronic hemodialysis, underwent to endoscopic removal of a rectal cancer. For disease staging, a total body TC with i.c.m. was performed. The following morning, patient showed a soft and aching bilateral paroditidis swelling. Salivary glands ultrasound was diagnostic for sialadenitis. The patient was rapidly treated with betamethasone following by a 240 minutes post-dilution online hemodiafiltration session. Results: Within the next 24h, a complete remission of IM was obtained. Conclusion: In our patient, a compensatory hyperactivity of the sodium / iodine symporter (NIS) on salivary gland cells may have played a crucial role in IM induction. An high efficiency hemodialysis session within the few following hours after i.c.m injection is a fundamental tool in patients on renal replacement treatment to prevent IM that is an epiphenomenon of i.c.m. accumulation.

AB - The purpose of this study is to describe the clinical case of a patient suffering from a gland carcinoma with bilateral inguinal and pelvic lymph node metastases in treatment with weekly administrations of Docetaxel. After two therapy cycles, the patient developed an atypical uremic hemolytic Syndrome (SEUa), treated with infusions of frozen fresh plasma, hemodialysis, and antibiotics. Because of a severe septic secondary complication on an extensive lymph node abscess, the administration of Eculizumab was not possible. The patient survived the mentioned Syndrome and is currently in periodic dialysis treatment. PMID- 29582963 TI - [Day of Prevention of Renal Diseases in Amatrice, Italy]. AB - Chronic kidney disease (CKD) is a very common condition and its prevalence is increasing worldwide. The CARHES study in Italy showed a prevalence of 6.5% in women and 7.5% in men. As a matter of fact, an early diagnosis is essential to slow down the progression and improve the renal and cardiovascular prognosis. For this purpose the A.N.Di.P. association (National Association of Peritoneal Dialysis-Onlus "Enzo Siciliano ") organized the DAY OF PREVENTION OF RENAL DISEASES which was held in AMATRICE the 15th of July 2017 called "WE START A NEW PATH OF LIFE TOGETHER". The goal of this initiative was to highlight and spread the importance of prevention and early diagnosis of renal disease in Amatrice and its surroundings. During this day, medical history, blood pressure measurements, urinalysis, serum creatinine and serum uric acid were carried out and we suggested to patients how to proceed, if necessary, in a further diagnostic and therapeutic process. We also recommended a correct lifestyle, based on healthy eating and regular physical activity. The choice to dedicate particular attention to the population tragically affected by the earthquake occurred to identify renal diseases, since they are a possible consequence of the earthquake, to draw attention to the importance of renal function and to demonstrate that simple routine checks may lead to an early diagnosis of unrecognized kidney diseases, also reducing cardiovascular risk. PMID- 29582964 TI - [The "Nephrology outpatient Triage": an organizational model for the ambulatory care of patients with advanced renal disease]. AB - The clinical course of outpatients with advanced chronic kidney disease requires a close monitoring by the nephrology team, in order to identify emerging clinical problems promptly and prevent subsequent complications. With the aim of improving the outpatient management in our clinic dedicated to advanced renal failure, we implemented the "Nephrology Clinic Triage" (NCT). This organizational model is coordinated by the nephrologist and supported by nurses. In case the outpatients, or their caregivers, have clinical problems or need advice, they can easily get in touch with a nephrology nurse by a dedicated telephone line. The nurse, who had been specifically trained for this purpose, interviews the patient by telephone and track his health conditions using dedicated flow-charts. The patients must be able to answer in a suitable way to the telephone interview on which NCT is based. Therefore, all patients referring to nephrology clinic are trained to record and report properly by telephone some relevant clinical parameters (i.e., blood pressure, body temperature, heart rate, body weight, urine volume) and clinical signs (dyspnea, dysuria, diarrhea, nausea, vomiting, abdominal/lumbar/chest pain). On the basis of the information obtained by means of NCT, the nurse can identify the patient's need and classify its severity and priority by means of a color-coding system. The subsequent medical intervention (telephone conversation, scheduled appointment, hospitalization) is planned accordingly. The implementation of NCT may be useful to monitor the clinical course of outpatients with advanced chronic renal failure also when they are home, thereby reducing the risk of harmful complications and hospitalization.

AB - Background: Fabry disease is a rare genetic lysosomal storage disease, inherited in an X-linked manner, characterized by lysosomal deposition of globotriaosylceramide due to deficient activity of the enzyme alpha-galactosidase A. Because the prevalence of this genetic disorder is unknown in the Emilia Romagna region, we conducted a screening study to assess the prevalence of Fabry disease in the city of Modena, Italy. Material and Methods: A screening study has been conducted in patients on renal replacement therapy at University Hospital of Modena. Screening tests have been performed using dried blood spot method. Alpha galactosidase A activity and Lyso-Gb3 levels were evaluated in peripheral blood of all men. In women test based on genetic analysis; Lyso-Gb3 was measured only in patients with mutation of gene GLA. Results: Screening tests have been performed on 388 subjects: 181 maintenance hemodialysis patients, 166 kidney transplant recipients and 41 peritoneal dialysis patients. About 40% of the patients did not had etiological diagnosis of renal disease. Lyso-Gb3 was more specific test than alpha- galactosidase A (100% vs. 82.5%) to diagnose Fabry disease. We found two different mutations: c.13 A >G p.(Asn5Asp), a variant likely benign and c.937 G >T p.(Asp313Tyr) a variant of uncertain significance. Both the patients carrying these genetic mutations had no symptoms or medical history compatible with Fabry disease. Conclusion: Identification of variant of uncertain significance such as c.937G >Tp.(Asp313Tyr) showed the limits of genetic analysis to diagnose an inherit disease. Further studies are need to assess the diagnostic value of Lyso-Gb3 for screening for Fabry disease. PMID- 29582966 TI - [Extra-hepatic manifestations associated with Hepatitis and virus infection]. AB - Hepatitis E virus (HEV) is a significant public health problem that affects almost 20 million individuals annually and cause acute liver injury in 3,5 million. Hepatitis E virus can cause acute, fulminant and chronic hepatitis and has been associated with a range of extrahepatic manifestation. The spectrum of these manifestation is still emerging. Acute pancreatitis and neurological, renal, hematologic, and muscoloskeletal manifestations have been described. Renal injury include membranoproliferative glomerulonephritis with or without cryoglobulinemia, membranous glomerulonephritis and tubular necrosis. The etiopathogenesis of extrahepatic manifestation is only supposed. It could be caused by a direct tossic effect of HEV or by an autoimmune process. We report a case of a 46 years old man who presented with acute hepatitis E. He was diagnosed to have acute severe renal failure and severe pancreatitis due to hepatitis E. Few cases have been reported in the literature concerning patients suffering from hepatitis E and severe extraepatic manifestations with a benign course and complete recovery.

AB - OBJECTIVES: Neurosurgical surgical site infections (SSI) are life-threatening complications, requiring medical treatment and additional surgeries and remain a substantial cause of morbidity. In order to identify the incidence and the main risk factors for SSI, we developed the Prophylaxis with Antibiotic protocol for neuroSurgical Site Infections Study (PASSIS), a prospective observational multicenter cohort study for examining a large number of neurosurgical procedures. METHODS: The study PASSIS involved four Italian Neurosurgical Departments applying the same antibiotic prophylaxis (ABP) protocol on 6359 consecutive neurosurgical procedures. In high-risk conditions (intra-operative contamination and/or post-operative cerebro-spinal fluid (CSF), and/or subcutaneous drainage and/or post-operative hyperpyrexia), and in presence of wound complication (CSF leak and/or CSF collection and/or wound diastasis), a prolongation protocol was prescribed. RESULTS: The crude rate of SSI in the whole series was and 1.7% for patient and 1.5% for procedure. Patient related SSI risk factors: Younger patients (<=14 years) had a significantly higher SSI risk compared with older patients (RR: 2.17; CI 95%: 1.13- 4.14). Patients underwent two surgeries were at increased SSI risk (RR: 3.80; CI 95% 2.33-6.18), and the risk increased with the number of surgeries. Surgeries lasting longer than 3 hours (RR: 2.27; CI 95% 1.15-4.50), undergoing two or more surgeries and the presence of prosthetic implants (RR: 2.40; CI 95% 1.53- 3.77) were procedure related SSI risk factors positively associated with SSI. In high-risk conditions and in wound complication as defined previously, ABP prolongation showed limited efficacy (RR:1.97; CI 95% 1.21-3.22 and 9.31; CI 95% 5.90-14.68 respectively). CONCLUSIONS: The subjects submitted to complicated, repeated, long lasting craniotomies, especially if experiencing postoperative deterioration, display the higher risk of SSIs, as a final life threatening complication. In order to reduce the SSI rate, further studies should address to design tailored prophylaxis protocols for each high risk situation as hereby defined; the wound complications deserve an increased microbiological surveillance, focusing the attention on the timing and source of infections.

AB - BACKGROUND: The endoscopic approach has been introduced in the clinical practice in 1980 with the aim to remove the pro- lapsed disk and free the compressed nerve using the least disruptive surgical technique, assuring in the same time, the resolution of the symptoms and a faster return back to normal life activity. Over the years, thanks to an extraordinary technical improvement either in terms of quality of images and development of many dif- ferent tailored instrumentations there has been a huge spreading of the endoscope use across the different surgical fields. For this reasons the transforaminal percutaneous endoscopic lumbar discectomy can be con- sidered, at the moment, the least invasive procedure for the removal of lumbar disc prolapsed. The aim of this study was to analyze the clinical outcome and complications rate on a large cumulative series operated on in two years period. METHODS: We present a retrospective series involving 270 cases of lumbar disk herniation managed surgically only by a percutaneous transforaminal endoscopic technique in two units and by two surgeons. All patients have a minimum follow-up of 6 months. Primary study end points were evaluation of out- comes using the Visual Analogue Scale and Oswestri Disability Index pre-operatively and at 3, 6 and 12 month as well as the complications and the recurrence rates. RESULTS: Our results, with a positive outcome around 93%, confirm the effectiveness of transforaminal per- cutaneous endoscopic discectomy in the treatment of lumbar disc herniation when compare to open microdiscectomy. Also the complications (5,5%) and the recurrence rate (4,1%) can be considered within the standard results. CONCLUSIONS: The transforaminal percutaneous endoscopic lumbar discectomy is a safe and effective procedure to treat lumbar disc prolapsed. Surgical experience and correct patients' selection are crucial factors affecting the outcome. PMID- 29582974 TI - Contemporary tools in arteriovenous malformations surgery. AB - Arteriovenous malformations (AVMs) are rare entities and therefore considered the main challenge for a neurosurgeon. Since the publication of the ARUBA study, one of the most popular debate regards the actual surgical indication for unruptured AVMs. Our group recently published a multicenter review of more than 500 cases underlying the important role of surgery. Over the last few decades, the expanding technologies used in the treatment of AVMs have shown an ongoing improvement overcoming some of the existing difficulties and shortcomings. In this paper, we reviewed the present literature to illustrate the main contemporary tools that, in our opinion, are crucial to obtain the best surgical and clinical outcome. Indocyanin green is nowadays considered a gold standard to identify arterial feeders, draining veins, and to detect any eventual residual. The use of non-stick, bipolar, 2-mm blade microclips, and thulium laser allows to obtain a better bleeding control and nidus removal. The development of the intraoperative ultrasound with neuronavigation, angiosonography, and color Doppler improves the accuracy of AVM resection. Moreover, improvements have been developed with the use of intraoperative micro-Dopplers combined with flow measurements, which consent to verify the gradual reduction of flow through draining veins. The possibility to perform functional preoperative studies and intraoperative monitoring can be considered as an essential point in the decision making in eloquent or near-eloquent AVMs. Furthermore, the hybrid operating room represents the best expression of an excellent neurovascular team where the use of the intraoperative angiography allows neurosurgeons and neurointerventional radiologists to work at the same time in a combined approach to achieve the best surgical removal. PMID- 29582975 TI - Feasibility of endoscopic endonasal approach for clip application of cerebral aneurysms: a systematic review. AB - INTRODUCTION: While open, microsurgical clipping and endovascular coiling remain the gold standards for treatment of cerebral aneurysms, a growing number of aneurysms treated via endoscopic endonasal methods have been reported in the literature. The aim of this study was to conduct a systematic review of the literature to gain a more thorough appreciation of the potential benefits and drawbacks of the endoscopic endonasal strategy in this setting. EVIDENCE ACQUISITION: We performed a detailed systematic review of the medical literature on endoscopic endonasal skull base surgery for treatment of cerebral aneurysms utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We identified 9 clinical studies describing treatment of 23 aneurysms utilizing the EEA. 11 additional cadaveric studies investigating aspects of operative exposure and/or technique in this setting were identified. The full text of these articles was reviewed. EVIDENCE SYNTHESIS: In the 9 clinical studies that met inclusion criteria, 23 aneurysms were treated in 21 patients. The mean patient age was 52.6 years. 15 aneurysms were unruptured and 8 were ruptured. 14 aneurysms involved the anterior circulation and 9 involved the posterior circulation. In 21 of 23 aneurysms, complete occlusion was achieved with endonasal clipping. Two aneurysms required additional treatment that included a takeback for clip repositioning and staged endovascular coiling. Complications included post-operative CSF leak (23.8%), stroke (19%), and meningitis (14.3%). Analysis of the combined literature revealed a significantly higher rate of CSF leak with endonasal clipping of posterior circulation aneurysms compared to anterior circulation aneurysms (P=0.047, Fisher's Exact Test). While there was a trend towards increased post- operative neurologic deficit following EEA for posterior circulation aneurysms, this did not reach statistical significance (P=0.063). The majority of post-operative complications in posterior circulation aneurysms occurred during clip application of aneurysms at the level of the basilar apex. In addition to the aforementioned clinical reports, 11 cadaveric studies were identified. 4 of these reports investigated approaches for individual anterior circulation aneurysms, 5 investigated approaches for posterior circulations aneurysms, and 2 involved both anterior and posterior circulation aneurysms. CONCLUSIONS: Despite a moderate increase in utilization, caution should be exercised when choosing an endonasal strategy for treatment of aneurysmal pathology over more traditional and established methods such as microsurgical clip application and endovascular methods. Anecdotal evidence suggests that inferior and/or medial projecting aneurysms involving the paraclinoid ICA not amenable to traditional open/endovascular strategies may be reasonable to consider for EEA clip application. Wide-necked, midline, ventrolaterally-projecting aneurysms involving the vertebrobasilar system may represent an additional exception, as long as the location along the rostrocaudal axis is low enough so as not to compromise visualization. Future improvements in operative technology, including anticipated advances in endoscopic 3-D visualization, may further alter the landscape of treatment involving this complex pathology. PMID- 29582976 TI - Radiosurgery and radiotherapy for arteriovenous malformations: outcome predictors and review of the literature. AB - Arteriovenous malformations (AVMs) are rare congenital vascular pathologies. The reported overall annual hemorrhage rate is 3.0%, for unruptured AVMs it is 2.2%, and for ruptured AVMs, 4.5%. The main goal of AVM treatment is to prevent intracerebral hemorrhage. This is achieved by complete nidus eradication. Interventional treatment options include microsurgery, embolization and radiosurgery, as well as multimodal approaches. Radiosurgery is a safe and effective alternative to surgery or embolization, especially for AVMs located in deep or eloquent brain regions, where invasive treatment cannot be performed. With the introduction of the Leksell Gamma Knife, AVMs became one of the most common indications for radiosurgical interventions (nearly 30% of the first 15 year experience). The current review discusses the role of radiosurgery in the treatment of AVMs, with a focus on outcome predictors and a discussion of the relevant literature. PMID- 29582977 TI - Surgical technique and nuances in ruptured versus unruptured arteriovenous malformation surgery. AB - Because of the more frequent use of noninvasive imaging methods, arteriovenous malformation (AVM) are gaining more attention. Population based studies reveal that about 35% to 50% of patients with AVM initially present with hemorrhage. Prior hemorrhage is the most consistent risk factor for future hemorrhage, other risk factors include deep venous drainage pattern, deep location, and so on. Surgical interventions, including surgical excision, intravascular intervention, and stereotactic radiation, have been developed with the aim to eliminate this source of hemorrhage. Among these methods, surgical excision was considered to be the gold standard for low grade intracranial AVMs. In ruptured AVMs, it is standard to wait several weeks to allow for patient recovery, hematoma liquefaction, and inflammatory reactions to subside, except for the life threatening hemorrhage. By separating the nidus from adjacent brain (the combined effects of the hematoma cavity and encephalomalacia), the hematoma creates a space for operator and facilitates AVM resection actually. There are some surgical nuances in ruptured versus unruptured AVM surgery. Detailed preoperative preparation is necessary to evaluate the general situation, neurological status, AVM architecture characteristic before surgery. Essential assistant technique, reasonable strategy and meticulous operative skill are crucial for the safety and validity of AVM resection.

AB - Arteriovenous malformation (AVM) of the brain is a rare condition with an estimated incidence rate of 2.05 cases per 100,000 person-years,1 primarily treated in specialized clinics. To prevent AVM from bleeding, treatment via microsurgery, Stereotactic Radiosurgery or Endovascular Embolism can be undertaken. The success of surgically treated patients largely depends also on the proper postoperative management of the patient. This review will focus on the postoperative management after surgical treatment with specific emphasis on the unique condition in patients with an Arteriovenous Malformation, imaging routine postoperatively and follow-up after microsurgical resection of an AVM, presenting the current state in the literature. Here, the focus shall be on so called low grade AVM, namely Spetzler-Martin grade I and II, which are preferably treated surgically rather than radiosurgical or endovascular. PMID- 29582980 TI - Embolization before stereotactic radiosurgery for the treatment of brain arteriovenous malformations. AB - Embolization is commonly used for the treatment of brain arteriovenous malformations (AVMs) prior to stereotactic radiosurgery (SRS). Due to mixed outcomes, however, its use remains controversial. This article is a review of recent studies assessing the efficacy of pre-radiosurgical embolization for brain AVMs. Articles published between 1990 and 2017 on the subject of pre radiosurgical AVM embolization were retrieved from PubMed. A literature review was performed on the selected studies to compare obliteration, hemorrhage, and complication rates from groups treated with embolization prior to radiosurgery to those treated without embolization. Overall, the studies reviewed demonstrate mixed results on the efficacy of pre-radiosurgical AVM embolization. For large, complex AVMs, embolization prior to radiosurgery may have a role in carefully selected patients performed by experienced practitioners. PMID- 29582979 TI - Contemporary endovascular techniques for the curative treatment of cerebral arteriovenous malformations and review of neurointerventional outcomes. AB - INTRODUCTION: Since the first landmark randomized trials on unruptured bAVMs were published, there has been emerging concerns about the role of endovascular therapy. For bAVMs considered inoperable, embolization remains an option worth considering, especially in young patients presenting with a rupture. We aimed to review the curative potential of contemporary stand-alone embolization techniques enabling high occlusion rates and their respective short and long term safety profile. EVIDENCE ACQUISITION: We performed a PubMed search with the terms "curative embolization of brain arteriovenous malformations" and "endovascular cure of brain arteriovenous malformations" focusing on the last ten years (2008 2018) and compliant to the PRISMA reporting guidelines. We then screened the prospective and retrospective studies of pediatric or adult populations that contained patient demographics, ruptured or unruptured presentation, and bAVM grade according to the Spetzler-Martin (SM) classification, exclusive or stand alone endovascular treatment without previous embolization, micro-, radio- or stereotactic surgery, number of sessions, type of access, technique(s) and embolic agents used, rate of angiographically confirmed complete occlusion at least 3 months after obliteration stratified by AVM grade or subtype, as well as neurological status and treatment-associated outcome based on the modified Rankin scale at admission, discharge and within 12 months following curative embolization, rated by an independent observer. EVIDENCE SYNTHESIS: Given the heterogeneity of the reported data, multiple confounding factors, overwhelming number of unpowered studies, lack of homogenous control groups and poor compliance to PRISMA reporting guidelines in most of the interventional literature, we were unable to obtain solid data and perform a statistical meta analysis on the safety and effectiveness of curative embolization. Consequently, we decided to cover a selection of salient topics. CONCLUSIONS: Stand-alone curative embolization, as well as exclusive microsurgery or radiosurgery each play complementary roles. Hemorrhagic, deep-seated lesions are an interesting subtype of surgically unfavorable bAVMs that may benefit from exclusive transvenous embolization, when carefully selected. Larger randomized trials and prospective registries are needed to establish the place of stand-alone or neoadjuvant endovascular treatment.

AB - Predicting long-term outcome after severe traumatic brain injury (TBI) is difficult, but accurate assessment is paramount for both families of the patients and medical decision-making, as well as quality assurance or research purposes. Many important prognostic factors for patients with severe TBI have been identified, but most - if not all - including the Glasgow Coma Score and magnetic resonance imaging are not accurate enough to be used alone to predict patient outcomes. Clinicians should also be wary about how their predictions and decision making can be affected by heuristics and cognitive biases. Well-validated prognostic models, including the CRASH and IMPACT models, are easily available and, provided their limitations are appreciated, they offer an enormous potential to assist clinicians to objectively prognosticate the outcomes of patients with severe TBI by reducing the unduly influence of subconscious heuristics and cognitive biases. Finally, we also should not underestimate human being's adaptability, including their ability to recalibrate what may be acceptable to them when life circumstances have changed. Predicting outcome and decision-making after severe TBI requires a deep understanding of both science and humanity - a task we should all take seriously.

AB - This article invites us to think about the learning process, giving special attention to what we do not know, the recognition of ignorance, and the activation of the desire to learn. It proposes to revisit the mental patterns that might interfere with the learning process.

PMID- 29582982 TI - [Ramadan and diabetes mellitus in adult muslim population]. AB - Background: Although sick people are exempted from performing Ramadan, it is estimated that approximately 50 million people with diabetes mellitus (DM) fast during this month. Objective: To explore the relationship between Ramadan and DM in adult Muslim population as well as management and recommendations from literature related with this issue. Method: A narrative review was carried out in PubMed, Cochrane and Cuiden, databases, using controlled and free language for the period 2009-2014, and language filters (Spanish and English). Content analysis of selected documents in order to find emerging thematic categories was conducted. Results: The results have been organized into five thematic categories: the desire for Ramadan; changes that occur in the body by fasting; complications from fasting; control of DM during fasting; knowledge of healthcare professional. Conclusion: Those believers who wish to take part in Ramadan and suffering DM, have to go to their health care professional before performing because, although people with good control can perform the fast, the treatment must be individualized, considering the composition and amount of food they are going to eat.

AB - Producing and maintaining specific liquid patterns during evaporation holds great potential for techniques of printing and coating. Here we report the control over the evolution of surfactant solution droplets on the micropyramid substrates during evaporation. The polygonal droplet shape is achieved during the drying rather than solely at the beginning. As the initial surfactant concentration is 0.04 mM, the droplet maintains its initial octagonal shape throughout the lifetime. Interestingly, the initial octagonal shape transforms into a square during the evaporation as the initial surfactant concentration reaches 0.8 mM. These findings can shed light on wetting pattern control for complex solutions required in various applications. PMID- 29582985 TI - Core-Satellite Supraparticles To Ballistically Stamp Nanostructures on Surfaces. AB - Nanostructured surfaces are of great importance in a very wide range of fields. They can be obtained by imprint or deposition techniques. However, these are usually sophisticated to perform. Generally, it is not easy to equip an object/product with a nanostructure after manufacturing. Yet, it would be very beneficial to achieve a modification of an arbitrary surface with a nanostructure of choice at a later stage by an approach that is simple to perform without the need of sophisticated equipment or excessive treatment by physicochemical methods. Herein, such a process is reported, which combines two "old-fashioned" techniques, namely, sandblasting and rubber-stamping, and translates them to the "nanoworld". By creating core-satellite supraparticles via spray-drying, a ballistic core-satellite stamp particle system is obtained, which can be used to easily transfer a wide range of nanoparticles to a great variety of surfaces to equip these with a nanostructure and subsequently advanced properties. These include water-repellant, antifouling, or antidust surfaces. Moreover, it is also demonstrated that the approach can be used to manufacture well-defined nanoimprinted surfaces. Such surfaces showed an improved spreading behavior for aliphatic alcohols, thus making such surfaces, for instance, very susceptible for disinfectants. All in all, the simple technique described herein has a great potential for creating nanostructured surfaces on nearly any surface. PMID- 29582986 TI - Polyoxometalate-Promoted Electrocatalytic CO2 Reduction at Nanostructured Silver in Dimethylformamide. AB - Electrochemical reduction of CO2 is a promising method to convert CO2 into fuels or useful chemicals, such as carbon monoxide (CO), hydrocarbons, and alcohols. In this study, nanostructured Ag was obtained by electrodeposition of Ag in the presence of a Keggin type polyoxometalate, [PMo12O40]3- (PMo). Metallic Ag is formed upon reduction of Ag+. Adsorption of PMo on the surface of the newly formed Ag lowers its surface energy thus stabilizes the nanostructure. The electrocatalytic performance of this Ag-PMo nanocomposite for CO2 reduction was evaluated in a CO2 saturated dimethylformamide medium containing 0.1 M [ n Bu4N]PF6 and 0.5% (v/v) added H2O. The results show that this Ag-PMo nanocomposite can catalyze the reduction of CO2 to CO with an onset potential of 1.70 V versus Fc0/+, which is only 0.29 V more negative than the estimated reversible potential (-1.41 V) for this process and 0.70 V more positive than that on bulk Ag metal. High faradaic efficiencies of about 90% were obtained over a wide range of applied potentials. A Tafel slope of 60 mV dec-1 suggests that rapid formation of *CO2*- is followed by the rate-determining protonation step. This is consistent with the voltammetric data which suggest that the reduced PMo interacts strongly with CO2 (and presumably CO2*-) and hence promotes the formation of CO2*-. PMID- 29582987 TI - CeF3-Doped Porous Carbon Nanofibers as Sulfur Immobilizers in Cathode Material for High-Performance Lithium-Sulfur Batteries. AB - In this study, the CeF3-doped porous carbon nanofibers (PCNFs), prepared via electroblown spinning technique and carbonization process, are used as sulfur immobilizers in cathodes for lithium-sulfur (Li-S) batteries for the first time. The cathode composed of CeF3-doped PCNFs, carbon nanotubes (CNTs), and S is successfully prepared through the ball-milling and heating method. The formed porous structure in the PCNFs and CNTs facilitates the construction of highly electrically conductive pathways and effectively alleviates volume changes, which can maintain the stability of the cathode structure and make them in close contact between the electrodes. Meanwhile, the intermediate polysulfide dissolved and lost in the electrolyte can also be suppressed because of the hierarchical porous carbon nanofibers and CeF3. The Li-S battery using the cathode can display excellent electrochemical properties and stable capacity retention, presenting an initial discharge capacity of 1395.0 mAh g-1 and retaining a capacity of 901.2 mAh g-1 after 500 cycles at 0.5C. During the rate capability tests of battery, the discharge capacity of Li-S battery with the electrode slowed down from the discharge capacity of 1284.6 mAh g-1 at 0.5C to 1038.6 mAh g-1 at 1C and 819.3 mAh g-1 at 2C, respectively. It is noteworthy that the battery can still endow an outstanding discharge capacity of 1269.73 mAh g-1 with a high retention of 99.2% when the current density returns to 0.5C. PMID- 29582988 TI - Tuning Pseudocapacitance via C-S Bonding in WS2 Nanorods Anchored on N,S Codoped Graphene for High-Power Lithium Batteries. AB - Pseudocapacitance plays an important role in high-power lithium-ion batteries (LIBs). However, it is still lack of effective methods to tailor the pseudocapacitance contribution in electrode materials for LIBs. Herein, pseudocapacitance tuned by the strength of C-S bonding has been rendered in WS2 nanorods anchored on the N,S codoped three-dimensional graphene hybrid (WS2@N,S 3DG) for the first time. The pseudocapacitive contributions in the charge storage can be enhanced effectively with the increased strength of C-S bonding. As expected, the enhanced extrinsic pseudocapacitance makes WS2@N,S-3DG a fascinating electrode material for high-power LIBs, with a high reversible capacity of 509 mA h g-1 over 500 cycles at a current density as high as 2 A g-1. These encouraging results of pseudocapacitance tailored by chemical bonding provide new opportunities for designing advanced electrode materials. PMID- 29582989 TI - Facile Biofabrication of Heterogeneous Multilayer Tubular Hydrogels by Fast Diffusion-Induced Gelation. AB - Multilayer (ML) hydrogels are useful to achieve stepwise and heterogeneous control over the organization of biomedical materials and cells. There are numerous challenges in the development of fabrication approaches toward this, including the need for mild processing conditions that maintain the integrity of embedded compounds and the versatility in processing to introduce desired complexity. Here, we report a method to fabricate heterogeneous multilayered hydrogels based on diffusion-induced gelation. This technique uses the quick diffusion of ions and small molecules (i.e., photoinitiators) through gel-sol or gel-gel interfaces to produce hydrogel layers. Specifically, ionically (e.g., alginate-based) and covalently [e.g., gelatin methacryloyl (GelMA-based)] photocross-linked hydrogels are generated in converse directions from the same interface. The ML (e.g., seven layers) ionic hydrogels can be formed within seconds to minutes with thicknesses ranging from tens to hundreds of micrometers. The thicknesses of the covalent hydrogels are determined by the reaction time (or the molecule diffusion time). Multiwalled tubular structures (e.g., mimicking branched multiwalled vessels) are mainly investigated in this study based on a removable gel core, but this method can be generalized to other material patterns. The process is also demonstrated to support the encapsulation of viable cells and is compatible with a range of thermally reversible core materials (e.g., gelatin and Pluronic F127) and covalently cross-linked formulations (e.g., GelMA and methacrylated hyaluronic acid). This biofabrication process enhances our ability to fabricate a range of structures that are useful for biomedical applications. PMID- 29582990 TI - In Situ Inner Lumen Attachment of Heparin to Poly(ether sulfone) Hollow Fiber Membranes Used for Microdialysis Sampling. AB - An in situ chemical surface modification method to attach heparin to the inner lumen of a single hollow fiber poly(ether sulfone) (PES) membrane incorporated into a commercial microdialysis sampling device is described. The immobilization process uses gentle, room-temperature conditions with the enzyme laccase (E.C. 1.10.3.2) and 4-hydroxybenzoic acid (4HBA). The resulting functionalized inner membrane surface with a carboxylic acid functional groups allowed for (1-ethyl-3 (3-(dimethylamino)propyl) carbodimide)/ N-hydroxysuccinimide) EDC/NHS chemistry to attach heparin to the membrane surface. X-ray photoelectron spectroscopy measurements suggested successful attachment of 4HBA polymers and heparin onto the PES membrane. The microdialysis extraction efficiency after membrane surface modification was measured with model compounds fluorescein isothiocyanate (FITC) labeled dextrans and lysozyme and the cytokines acidic fibroblast growth factor (aFGF) and CXCL1 (KC/GRO). This work demonstrates an in situ method to modify commercially available PES hollow fiber microdialysis membranes with amine or carboxylic acid functional groups. PMID- 29582991 TI - Capacitive Pressure Sensor with High Sensitivity and Fast Response to Dynamic Interaction Based on Graphene and Porous Nylon Networks. AB - Flexible pressure sensors are of great importance to be applied in artificial intelligence and wearable electronics. However, assembling a simple structure, high-performance capacitive pressure sensor, especially for monitoring the flow of liquids, is still a big challenge. Here, on the basis of a sandwich-like structure, we propose a facile capacitive pressure sensor optimized by a flexible, low-cost nylon netting, showing many merits including a high response sensitivity (0.33 kPa-1) in a low-pressure regime (<1 kPa), an ultralow detection limit as 3.3 Pa, excellent working stability after more than 1000 cycles, and synchronous monitoring for human pulses and clicks. More important, this sensor exhibits an ultrafast response speed (<20 ms), which enables its detection for the fast variations of a small applied pressure from the morphological changing processes of a droplet falling onto the sensor. Furthermore, a capacitive pressure sensor array is fabricated for demonstrating the ability to spatial pressure distribution. Our developed pressure sensors show great prospects in practical applications such as health monitoring, flexible tactile devices, and motion detection. PMID- 29582992 TI - Effective Dual Polysulfide Rejection by a Tannic Acid/FeIII Complex-Coated Separator in Lithium-Sulfur Batteries. AB - The solubility behaviour of polysulfides in electrolyte solutions is a major bottleneck prior to the practical application of the lithium-sulfur battery. To address this issue, we fabricate a tannic acid/FeIII complex-coated polypropylene (PP) separator (TA/FeIII-PP separator) via a simple, fast, and green method. Benefiting from dual-confinement effects based on Lewis acid-base interactions between FeIII and polysulfides as well as the dipole-dipole interactions between rich phenol groups and polysulfides, the migration of polysulfides is effectively suppressed. Meanwhile, the porous structure of the PP separator is not destroyed by an additional coating layer. Thus, the TA/FeIII-PP separator can retain rapid lithium ion transport, eventually leading to a significant improvement in both the discharge capacity and rate performance of the corresponding lithium-sulfur cells. The cell with the TA/FeIII-PP separator presents a low capacity fade of 0.06% per cycle over 1000 cycles at 2.0 C, along with a high Coulombic efficiency of >97% over 300 cycles at 0.5 C. With respect to the one with the bare PP separator, the cell with the TA/FeIII-PP separator exhibits a 1.7-fold increase in the discharge capacity at 3.0 C. The proposed simple and economical approach shows great potential in constructing advanced separators to retard the shuttle effect of polysulfides for lithium-sulfur batteries. PMID- 29582993 TI - Carbapenems and Lipid Bilayers: Localization, Partitioning, and Energetics. AB - Carbapenems are broad-spectrum antibiotics used today to treat otherwise antibiotic resistant bacteria. As their target transpeptidase is located within the periplasm of the Gram-negative bacteria, they can participate in nonspecific interactions between the inner leaflet of the outer membrane and the outer leaflet of the inner membrane. We, therefore, studied the interaction of the four most clinically relevant carbapenems, namely, imipenem, doripenem, ertapenem, and meropenem, with model phospholipid bilayers made of 1,2-dimyristoyl- sn-glycero-3 phosphocholine (DMPC) using molecular dynamics (MD) simulations and X-ray diffraction at low and high concentration of the drugs corresponding to 1 and 8 mol % (with respect to the number of membrane lipids). Membrane solubility was found to decrease from imipenem to doripenem, ertapenem, and finally meropenem. At low concentrations, membrane insertion was found to be a two step process, where the drugs first adsorb to the lipid head groups before inserting through a rotation of the molecule. At higher drug concentrations, the molecules were found to form aggregates in the aqueous phase before making contact with the membranes and spontaneously inserting into the bilayers. Two populations of imipenem were found: in the headgroup at ~17 A from the bilayer center and an inserted population at z-values of about 7 A. Other carbapenems were found to localize in the tail groups with meropenem at ~10 A, doripenem at ~8 A, and ertapenem at ~8 A. The observed membrane solubility of carbapenems can potentially impact the availability of the drug to the target penicillin-binding proteins, potentially affecting their clinical efficacy. PMID- 29582994 TI - Analytical Cascades of Enzymes for Sensitive Detection of Structural Variations in Protein Samples. AB - Protein function critically depends on structure. However, current analytical tools to monitor consistent higher-order structure with high sensitivity, as for instance required in the development of biopharmaceuticals, are limited. To complement existing assays, we present the analytical cascade of enzymes (ACE), a method based on enzymatic modifications of target proteins, which serve to exponentially amplify structural differences between them. The method enables conformational and chemical fingerprinting of closely related proteins, allowing for the sensitive detection of heterogeneities in protein preparations with high precision. Using this method, we detect protein variants differing in conformation only, as well as structural changes induced by diverse covalent modifications. Additionally, we employ this method to identify the nature of structural variants. Moreover, the ACE method should help to address the limited reproducibility in fundamental research, which partly relates to sample heterogeneities. PMID- 29582995 TI - Quasi-aromatic Mobius Metal Chelates. AB - We report the design as well as structural and spectroscopic characterizations of two new coordination compounds obtained from Cd(NO3)2.4H2O and polydentate ligands, benzilbis(pyridin-2-yl)methylidenehydrazone (LI) and benzilbis(acetylpyridin-2-yl)methylidenehydrazone (LII), in a mixture with two equivalents of NH4NCS in MeOH, namely [Cd(SCN)(NCS)(LI)(MeOH)] (1) and [Cd(NCS)2(LII)(MeOH)] (2). Both LI and LII are bound via two pyridyl-imine units yielding a tetradentate coordination mode giving rise to the 12 pi electron chelate ring. It has been determined for the first time (qualitatively and quantitatively), using the EDDB electron population-based method, the HOMA index, and the ETS-NOCV charge and energy decomposition scheme, that the chelate ring containing CdII can be classified as a quasi-aromatic Mobius motif. Notably, using the methyl-containing ligand LII controls the exclusive presence of the NCS connected with the CdII atom (structure 2), while applying LI allows us to simultaneously coordinate NCS- and SCN- ligands (structure 1). Both systems are stabilized mostly by hydrogen bonding, C-H...pi interactions, aromatic pi...pi stacking, and dihydrogen C-H...H-C bonds. The optical properties have been investigated by diffused reflectance spectroscopy as well as molecular and periodic DFT/TD-DFT calculations. The DFT-based ETS-NOCV analysis as well as periodic calculations led us to conclude that the monomers which constitute the obtained chelates are extremely strongly bonded to each other, and the calculated interaction energies are found to be in the regime of strong covalent connections. Intramolecular van der Waals dispersion forces, due to the large size of LI and LII, appeared to significantly stabilize these systems as well as amplify the aromaticity phenomenon. PMID- 29582996 TI - Conventional-Flow Liquid Chromatography-Mass Spectrometry for Exploratory Bottom Up Proteomic Analyses. AB - Due to its sensitivity and productivity, bottom-up proteomics based on liquid chromatography-mass spectrometry (LC-MS) has become the core approach in the field. The de facto standard LC-MS platform for proteomics operates at sub MUL/min flow rates, and nanospray is required for efficiently introducing peptides into a mass spectrometer. Although this is almost a "dogma", this view is being reconsidered in light of developments in highly efficient chromatographic columns, and especially with the introduction of exceptionally sensitive MS instruments. Although conventional-flow LC-MS platforms have recently penetrated targeted proteomics successfully, their possibilities in discovery-oriented proteomics have not yet been thoroughly explored. Our objective was to determine what are the extra costs and what optimization and adjustments to a conventional-flow LC-MS system must be undertaken to identify a comparable number of proteins as can be identified on a nanoLC-MS system. We demonstrate that the amount of a complex tryptic digest needed for comparable proteome coverage can be roughly 5-fold greater, providing the column dimensions are properly chosen, extra-column peak dispersion is minimized, column temperature and flow rate are set to levels appropriate for peptide separation, and the composition of mobile phases is fine-tuned. Indeed, we identified 2 835 proteins from 2 MUg of HeLa cells tryptic digest separated during a 60 min gradient at 68 MUL/min on a 1.0 mm * 250 mm column held at 55 degrees C and using an aqua-acetonitrile mobile phases containing 0.1% formic acid, 0.4% acetic acid, and 3% dimethyl sulfoxide. Our results document that conventional-flow LC MS is an attractive alternative for bottom-up exploratory proteomics. PMID- 29582997 TI - Co(III) Complexes with N2S3-Type Ligands as Structural/Functional Models for the Isocyanide Hydrolysis Reaction Catalyzed by Nitrile Hydratase. AB - It has been before reported that, in addition to hydration of nitriles, the Fe type nitrile hydratase (NHase) also catalyzes the hydrolysis of tert butylisocyanide ( tBuNC). In order to investigate the unique isocyanide hydrolysis by NHase, we prepared three related Co(III) model complexes, PPh4[Co(L)] (1), PPh4[Co(L-O3)] (2), and PPh4[Co(L-O4)] (3), where L is bis( N-(2 mercapto-2-methylpropionyl)aminopropyl)sulfide. The suffixes L-O3 and L-O4 indicate ligands with a sulfenate and a sulfinate and with two sulfinates, respectively, instead of the two thiolates of L. The X-ray analyses of 1 and 3 reveal trigonal bipyramidal and square pyramidal structures, respectively. Complex 2, however, has five-coordinate trigonal-bipyramidal geometry with eta2 type S-O coordination by a sulfenyl group. Addition of tBuNC to 1, 2, and 3 induces an absorption spectral change as a result of formation of an octahedral Co(III) complex. This interpretation is also supported by the crystal structures of PPh4[Co(L-O4)( tBuNC)] (4) and (PPh4)2[Co(L-O4)(CN)] (5). A water molecule interacts with 3 but cannot be activated as reported previously, as demonstrated by the lack of absorption spectral change in the pH range of 5.5-10.2. Interestingly, the coordinated tBuNC is hydrolyzed by 2 and 3 at pH 10.2 to produce tBuNH2 and CO molecule, but 1 does not react. These findings provide strong evidence that hydrolysis of tBuNC by NHase proceeds not by activation of the coordinated water molecule but by coordination of the substrate. The mechanism of the hydrolysis reaction of tBuNC is explained with support provided by DFT calculations; a positively polarized C atom of tBuNC on the Co(III) center is nucleophilically attacked by a hydroxide anion activated through an interaction of the sulfenyl/sulfinyl oxygen with the nucleophile.

AB - Due to its unusual optical properties, neodymium ion (Nd3+)-doped bismuth silicate (Bi4Si3O12, BSO) is widely used for its excellent medium laser amplification in physics, chemistry, biomedicine, and other research fields. Although the spectral transitions and luminescent mechanisms of Nd3+-doped BSO have been investigated experimentally, theoretical research is severely limited due to the lack of detailed information about the microstructure and the doping site of Nd3+-doped BSO, as well as the electric and magnetic dipole transition mechanisms. Herein, we systematically study the microstructure and doping site of Nd3+-doped BSO using an unbiased CALYPSO structure search method in conjunction with first-principles calculations. The result indicates that the Nd3+ ion impurity occupies the host Bi3+ ion site with trigonal symmetry, forming a unique semiconducting phase. Based on our newly developed WEPMD method, the electric dipole and magnetic dipole transition lines, including a large number of absorption and emission lines, in the region of visible and near-infrared spectra of Nd3+-doped BSO are calculated. It is found that the 4G5/2 -> 4I9/2, 2H9/2 -> 4I9/2, and 4F3/2 -> 4I11/2 channels are promising laser actions of Nd3+-doped BSO. These findings indicate that Nd3+-doped BSO crystals can serve as a promising multifunctional material for optical laser devices.

AB - New approaches for the synthesis of enantiopure trifluoromethylthiolated molecules by chiral selenide-catalyzed allylic trifluoromethylthiolation and intermolecular difunctionalization of unactivated alkenes are disclosed. In these transformations, functional groups were well tolerated, and the desired products were obtained in good yields with excellent chemo-, enantio-, and diastereoselectivities. This reaction is nicely complementary to enantioselective trifluoromethylthiolation, allylic functionalization, and intermolecular alkene difunctionalization. PMID- 29583002 TI - Salt-Induced Control of the Grafting Density in Poly(ethylene glycol) Brush Layers by a Grafting-to Approach. AB - In this work, a method to obtain control of the grafting density during the formation of polymer brush layers by the grafting-to method of thiolated poly(ethylene glycol) onto gold is presented. The grafting density of the polymer chains was adjusted by adding Na2SO4 in concentrations between 0.2 and 0.9 M to the aqueous polymer solution during the grafting process. The obtained grafting densities ranged from 0.26 to 1.60 chains nm-2, as determined by surface plasmon resonance. The kinetics of the grafting process were studied in situ by a quartz crystal microbalance with dissipation, and a mushroom to brush conformational transition was observed when the polymer was grafted in the presence of Na2SO4. The transition from mushroom to brush was only observed for long periods of grafting, highlighting the importance of time to obtain high grafting densities. Finally, the prepared brush layer with the highest grafting density showed high resistance to the adsorption of bovine serum albumin, while layers with a lower grafting density showed only limited resistance. PMID- 29583001 TI - Catalytic Diastereo- and Enantioselective Fluoroamination of Alkenes. AB - The stereoselective synthesis of syn-beta-fluoroaziridine building blocks via chiral aryl iodide-catalyzed fluorination of allylic amines is reported. The method employs HF-pyridine as a nucleophilic fluoride source together with mCPBA as a stoichiometric oxidant, and affords access to arylethylamine derivatives featuring fluorine-containing stereocenters in high diastereo- and enantioselectivity. Catalyst-controlled diastereoselectivity in the fluorination of chiral allylic amines enabled the preparation of highly enantioenriched 1,3 difluoro-2-amines bearing three contiguous stereocenters. The enantioselective catalytic method was applied successfully to other classes of multifunctional alkene substrates to afford anti-beta-fluoropyrrolidines, as well as a variety of 1,2-oxyfluorinated products. PMID- 29583003 TI - Ammonia Activation by Ce Atom: Matrix-Isolation FTIR and Theoretical Studies. AB - The activation of ammonia by cerium atom has been investigated in solid argon using infrared spectroscopy and density functional theoretical calculations. The results reveal that the spontaneous formation of CeNH3 complex on annealing is the initial step in the reactions of cerium atoms with ammonia. The CeNH3 complexes rearrange to generate the inserted HCeNH2 molecules on irradiation. A "triplet-singlet" spin conversion occurs along the reaction path in which HCeNH2 (3A") isomerizes into H2CeNH (1A'). The H2CeNH molecules finally decompose to yield HCeN + H2 upon photolysis. The periodic trend and differences for the M + NH3 (M = Ti, Zr, Hf, Ce, Th) systems are discussed on the basis of the present and previous works. DFT calculations predict that the most stable ground state for HHfNH2 and HThNH2 is singlet due to the stronger relativistic effects in Hf and Th atoms, while that for HTiNH2, HZrNH2, and HCeNH2 is triplet. Besides, the H2-elimination process is different for Ce and M (Ti, Zr, Hf, Th) cases. PMID- 29583004 TI - Effects of Stigmasterol and beta-Sitosterol on Nonalcoholic Fatty Liver Disease in a Mouse Model: A Lipidomic Analysis. AB - To study the effects of stigmasterol and beta-sitosterol on high-fat Western diet (HFWD)-induced nonalcoholic fatty liver disease (NAFLD), lipidomic analyses were conducted in liver samples collected after 33 weeks of the treatment. Principal component analysis showed these phytosterols were effective in protecting against HFWD-induced NAFLD. Orthogonal projections to latent structures-discriminate analysis (OPLS-DA) and S-plots showed that triacylglycerols (TGs), phosphatidylcholines, cholesteryl esters, diacylglycerols, and free fatty acids (FFAs) were the major lipid species contributing to these discriminations. The alleviation of NAFLD is mainly associated with decreases in hepatic cholesterol, TGs with polyunsaturated fatty acids, and alterations of free hepatic FFA. In conclusion, phytosterols, at a dose comparable to that suggested for humans by the FDA for the reduction of plasma cholesterol levels, are shown to protect against NAFLD in this long-term (33-week) study.

AB - Adsorption, self-organization, and mechanical properties of different fatty acid layers under different confinement states have been investigated as a function of the presence and conformation of one unsaturation in their aliphatic chain. In situ characterization, at the molecular level, was performed with the ATLAS molecular tribometer, in terms of rheology, forces, and thickness of confined fluid. The results demonstrate that the fatty acids adsorb on the surfaces by weak interactions and form viscoelastic films with a thickness of about 15 A on each surface. The adsorption kinetics, the packing of the self-assembled monolayers, and the coverage rate depend on the molecular architecture of the fatty acids and lead to various mechanical behaviors under confinement.

AB - The stereocontrolled synthesis of 2-deoxy-d- arabino-hexopyranosides ("galactopyranosides") using 3,4- O-isopropylidene-6- O- tert-butyldiphenylsilyl protected glycosyl donors is reported. 2-Deoxy-thioglycoside 3e gives excellent alpha-selectivity, while galactal 9 leads to, in a two-step protocol, 2-deoxy beta-glycosides in high stereoselectivity. The selectivity of both reagents is believed to arise from the combination of the isopropylidene acetal spanning O-3 and O-4 together with the sterically demanding silyl group on O-6. The utility of the method was demonstrated through the synthesis of a trisaccharide that contains both 2-deoxy alpha- and beta-d-galactopyranosyl residues.

AB - A novel and efficient copper-catalyzed cascade cyclization/trifluoromethylthiolation of unactivated olefins has been achieved with the stable and readily available AgSCF3 as the SCF3 source. A range of SCF3 substituted pyrrolines have been easily obtained under mild conditions in good yields via the present process. This method represents a facile and rapid access to valuable pyrrolines with fluorine-containing groups, and it is amenable to gram-scale synthesis. PMID- 29583009 TI - Hydrogelation Kinetics Measured in a Microfluidic Device with in Situ X-ray and Fluorescence Detection. AB - Efficient hydrogelators will gel water fast and at low concentrations. Small molecule gelling agents that assemble into fibers and fiber networks are particularly effective hydrogelators. Whereas it is straightforward to determine their critical concentration for hydrogelation, the kinetics of hydrogelation is more difficult to study because it is often very fast, occurring on the subsecond time scale. We used a 3D focusing microfluidic device combined with fluorescence microscopy and in situ small-angle X-ray scattering (SAXS) to study the fast pH induced gelation of a model small molecule gelling agent at the millisecond time scale. The gelator is a 1,3,5-benzene tricarboxamide which upon acidification assembles into nanofibrils and fibril networks that show a characteristic photoluminescence. By adjusting the flow rates, the regime of early nanofibril formation and gelation could be followed along the microfluidic reaction channel. The measured fluorescence intensity profiles were analyzed in terms of a diffusion-advection-reaction model to determine the association rate constant, which is in a typical range for the small molecule self-assembly. Using in situ SAXS, we could determine the dimensions of the fibers that were formed during the early self-assembly process. The detailed structure of the fibers was subsequently determined by cryotransmission electron microscopy. The study demonstrates that 3D focusing microfluidic devices are a powerful means to study the self-assembly on the millisecond time scale, which is applied to reveal early state of hydrogelation kinetics. In combination with in situ fluorescence and X ray scattering, these experiments provide detailed insights into the first self assembly steps and their reaction rates.

AB - A highly selective and practical asymmetric Ag(I) catalyst system has been developed for the [3 + 2] cycloaddition reactions between isocyanoacetates and cyclopentenediones. The current Ag(I) catalyst system tolerates moisture and air and readily utilizes class III solvents such as EtOAc and acetone. The development of on demand generation of an active chiral catalyst in the presence of isocyanides paves a way to the efficient asymmetric preparation of bicyclic pyrrolidines with four stereogenic centers, including two quaternary centers in 80-97% ee. PMID- 29583011 TI - Bimolecular Master Equations for a Single and Multiple Potential Wells with Analytic Solutions. AB - The analytic solutions, that is, populations, are derived for the K-adiabatic and K-active bimolecular master equations, separately, for a single and multiple potential wells and reaction channels, where K is the component of the total angular momentum J along the axis of least moment of inertia of the recombination products at a given energy E. The analytic approach provides the functional dependence of the population of molecules on its K-active or K-adiabatic dissociation, association rate constants and the intermolecular energy transfer, where the approach may complement the usual numerical approaches for reactions of interest. Our previous work, Part I, considered the solutions for a single potential well, whereby an assumption utilized there is presently obviated in the derivation of the exact solutions and farther discussed. At the high-pressure limit, the K-adiabatic and K-active bimolecular master equations may each reduce, respectively, to the K-adiabatic and K-active bimolecular Rice-Ramsperger-Kassel Marcus theory (high-pressure limit expressions) for bimolecular recombination rate constant, for a single potential well, and augmented by isomerization terms when multiple potential wells are present. In the low-pressure limit, the expression for population above the dissociation limit, associated with a single potential well, becomes equivalent to the usual presumed detailed balance between the association and dissociation rate constants, where the multiple well case is also considered. When the collision frequency of energy transfer, ZLJ, between the chemical intermediate and bath gas is sufficiently less than the dissociation rate constant kd( E' J' K') for postcollision ( E' J' K), then the solution for population, g( EJK)+, above the critical energy further simplifies such that depending on ZLJ, the dissociation and association rate constant kr( EJK), as g( EJK)+ = kr( EJK)A.BC/[ ZLJ+ kd( EJK)], where A and BC are the reactants, for example, relevant for O3 formation from O + O2 + Ar up to ~100 bar; otherwise, additional contributions from postcollision are present and especially relevant at high pressures. In the aforementioned regime ZLJ < kd( E' J' K) the physical connection of recombination rate constants, krec based on either utilizing population from the master equation approach or a collision based bimolecular RRKM theory is traced and elucidated analytically that the rate constants are equal. Recombination rate constants, krec, based on the population, are also given and considered for an adiabatic or active K. For example, for O3 formation in Ar bath gas, the K-adiabatic-based krec for O3 yields 4.0 * 10-34 cm6 molecule 2 s-1 at T = 300 K and 1 bar, in agreement with the experimental value, where the contribution from the population of metastable ozone is discussed and the adiabaticity of K highlighted. A facile numerical implementation of the formalism for g( EJK) and krec for O3 is noted. The application of the expressions to ozone recombination as a function of pressure and temperature is given elsewhere, beyond the selection considered here, for studying the physical features, including the contributions from the K and intermolecular energy transfer to the krec, and the puzzles reported from experiments for this reaction. PMID- 29583012 TI - Single-Photon Emitters in Boron Nitride Nanococoons. AB - Quantum emitters in two-dimensional hexagonal boron nitride (hBN) are attractive for a variety of quantum and photonic technologies because they combine ultra bright, room-temperature single-photon emission with an atomically thin crystal. However, the emitter's prominence is hindered by large, strain-induced wavelength shifts. We report the discovery of a visible-wavelength, single-photon emitter (SPE) in a zero-dimensional boron nitride allotrope (the boron nitride nanococoon, BNNC) that retains the excellent optical characteristics of few-layer hBN while possessing an emission line variation that is lower by a factor of 5 than the hBN emitter. We determined the emission source to be the nanometer-size BNNC through the cross-correlation of optical confocal microscopy with high resolution scanning and transmission electron microscopy. Altogether, this discovery enlivens color centers in BN materials and, because of the BN nanococoon's size, opens new and exciting opportunities in nanophotonics, quantum information, biological imaging, and nanoscale sensing.

AB - An asymmetric direct doubly vinylogous Michael addition has been developed for the generation of sterically congested vicinal quaternary and tertiary stereocenters. This doubly vinylogous Michael addition of beta,gamma-unsaturated butenolides to 3-methyl-4-nitro-5-alkenyl isoxazoles, powered by a bifunctional squaramide, affords a broad range of densely functionalized enantioenriched gamma,gamma-disubstituted butenolides in high yields with excellent diastereo- and enantioselectivities in most cases. Moreover, the strategy highlights the first application of beta,gamma-unsaturated butenolides in an asymmetric 1,6 conjugate addition. PMID- 29583014 TI - Herbal Prescriptions and Medicinal Herbs for Parkinson-Related Rigidity in Korean Medicine: Identification of Candidates Using Text Mining. AB - BACKGROUND: Dongeuibogam (DongYiBaoGian), one of the most important books in Korean medicine, comprises a comprehensive summary of all traditional medicines of North-East Asia before the 17th century. This medicinal literature was mined to establish a list of candidate herbs to treat Parkinson-related rigidity. METHODS: A systematic search for terms describing Parkinson-related rigidity and candidate prescriptions for the treatment of Parkinson-related rigidity in the Dongeuibogam was performed. A high-frequency medicinal herb combination group and candidates for the treatment of Parkinson-related rigidity were also selected through an analysis of medicinal herb combination frequencies. The existing literature pertaining to the potential effects of candidate herbs for Parkinson related rigidity was reviewed. RESULTS AND CONCLUSIONS: Ten medicinal herb candidates for the treatment of Parkinson-related rigidity were selected, and their respective precedent studies were analyzed. PMID- 29583016 TI - Preliminary study of Novafon local vibration voice therapy for dysphonia treatment. AB - BACKGROUND: The objective of this study was to explore the effectiveness of a five-week Novafon local vibration voice therapy (NLVVT) program for dysphonia treatment. METHODS: Eleven dysphonic subjects participated in this specific program. RESULTS: Treatment effects were assessed during (i.e. weekly) and after NLVVT. Large and significant treatment effects were revealed in acoustics (i.e. spectrography), and multiparametric indices (i.e. Acoustic Voice Quality Index (AVQI), and Dysphonia Severity Index (DSI)) during and after NLVVT (all p values < .01). Additionally, self-evaluation (i.e. Voice Handicap Index (VHI)) showed a significant improvement after NLVVT (p < .01). Gender independent voice range profile parameters (i.e. acoustics) only showed significant effects after treatment (p <= .01), but not during the treatment. Finally, aerodynamic measurement (i.e. phonation quotient) showed low treatment effects after NLVVT, which were not significant (p > .05). CONCLUSIONS: The preliminary results showed that NLVVT might be successful in voice treatment. Large treatment effects might be expected in AVQI, DSI, spectrography and VHI after using NLVVT. Other voice characteristics showed smaller treatment effects (i.e. voice range profile parameters) or no meaningful treatment effects (i.e. phonation quotient). PMID- 29583017 TI - Identification and characterization of cis-regulatory elements 'insulator and repressor' in PPARD gene. AB - AIM: Identification and functional characterization of cis-regulatory elements in human PPARD gene. METHODS: We used various bioinformatic tools on the publicly available human genome and Encyclopedia of DNA Elements databases to explore potential cis-regulatory elements in PPARD gene region. RESULTS: We predicted an insulator and an enhancer element in intron 2 of PPARD gene. Functional characterization using transient transfection, reporter assay and CTCF binding confirmed the insulator status. However, the predicted enhancer element showed repressor/silencer activity. Finally, we observed a potential interaction between these two cis-regulatory elements which is in agreement with 5C-Encyclopedia of DNA Elements data. CONCLUSION: We report two functionally validated cis regulatory elements in PPARD gene which will aid in understanding its regulation and role in metabolic functions. PMID- 29583018 TI - How patient-selected colors for removable appliances are reflected in electronically tracked compliance (wear times and wear behavior). AB - OBJECTIVES: A broad spectrum of colors for removable appliances, intended to optimize acceptance of treatment and patient cooperation, have been available on the dental market for years. This is the first study to analyze how patient selected colors are reflected in wear times and wear behavior of removable appliances. MATERIALS AND METHODS: The study included 117 children (55 girls and 62 boys) who were treated with active removable plate or functional appliances. All patients were offered to choose from 11 different colors, which were pooled into six groups (black, blue, green, yellow, pink, red) for analysis, or to combine any two to four colors ("multicolored" group) for their appliances. All appliances featured a built-in microsensor (TheraMon; MC Technology, Hargelsberg, Austria) for objective wear-time tracking. Differences between wear times were analyzed using pairwise t tests and Tukey correction. RESULTS: The longest median wear times were recorded in the blue and green groups (~11 h/d) and the shortest ones in the red and pink groups (~9 h/d), but they were not significantly influenced by the patient-selected colors. The median wear times involved an age related decrease by 0.56 h/y that was statistically significant ( P = .00005). No gender-specific patterns of wear behavior were observed. CONCLUSIONS: Patient selected colors for removable appliances can presumably improve acceptance of treatment, but they are not associated with statistically significant improvements in wear time or wear behavior. PMID- 29583015 TI - Effects of 90 Days of Resveratrol Supplementation on Cognitive Function in Elders: A Pilot Study. AB - OBJECTIVE: The purpose of this trial was to study the effects of chronic resveratrol use on cognitive function in humans. DESIGN: The authors conducted a double-blind, Phase IIa randomized, placebo-controlled trial to obtain preliminary estimates of the effects of resveratrol supplementation on cognitive function over a 90-day period in older adults. LOCATION: University of Florida in Gainesville, FL. SUBJECTS: Sedentary, overweight older adults (N = 32; age range: 65-93 years, M age = 73.34 years, SD age = 7.02 years). INTERVENTION: Participants were randomized to one of three treatment groups (placebo, 300 mg/day resveratrol, 1000 mg/day resveratrol) for 90 days. OUTCOME MEASURES: Cognitive function was assessed before and after treatment using a well characterized test battery: Trail Making, Digits Forward and Backward, Erikson Flanker, Controlled Oral Word Association, Hopkins Verbal Learning Test-Revised, and Task Switching. RESULTS: Psychomotor speed improved on the Trail Making Test part A in participants taking 1000 mg/day of resveratrol compared with participants in both the 300 mg/day condition and the placebo condition (p = 0.02). CONCLUSION: This pilot study suggests that 90 days of resveratrol supplementation at a dose of 1000/mg per day selectively improves psychomotor speed but does not significantly affect other domains of cognitive function in older adults. These findings provide modest support to further study the effects of resveratrol on cognitive function in older adults. PMID- 29583019 TI - Vaginal progesterone and the vaginal first-pass effect. AB - Vaginal progesterone is an effective alternative to systemic administration by oral or intramuscular use. The first-pass effect is reviewed, as are the most common uses for this route of delivery. This includes use in hormone replacement therapy, luteal support particularly in assisted reproduction, and avoidance of side-effects of oral progestins and progesterone. Vaginal progesterone represents a unique therapeutic solution to a number of clinical problems.

AB - In this review, we focused on original manuscripts published in the 2017 that provided additional information on the clinical and therapeutic features of the chronic obstructive pulmonary disease (COPD). We have chosen eight of these studies, collected in four topics concerning the pharmacological treatment (tiotropium) of mild-moderate patients, the pharmacological (fluticasone furoate/vilanterol/umeclidinium) and non-pharmacological treatment (non-invasive mechanical ventilation) of severe patients, the etiology of acute exacerbation of COPD involving seasonal airway pathogens and the role of eosinophils with particular interest to the monoclonal antibody directed against interleukin-5 (mepolizumab). For each topic, we report a brief description of studies, take home messages, and brief comments. PMID- 29583022 TI - Provider Information Provision and Breast Cancer Patient Well-Being. AB - Research continues to delineate and clarify specific communication behaviors associated with improved patient outcomes. In the context of breast cancer surgery, this exploratory study examined the effect of breast surgeon information provision on the immediate post-visit outcomes of patients' anxious preoccupation, intention to adhere to treatment recommendations, and treatment plan satisfaction. Participants included 51 newly diagnosed breast cancer patients receiving care from one breast surgeon at a National Cancer Institute designated cancer center in the northeastern United States. Participants completed pre- and post-visit questionnaires. Medical interactions were recorded, transcribed, and analyzed via multidimensional analysis, a method of linguistic analysis that uses exploratory factor analysis to identify how specific types of words are patterned and work to accomplish communicative goals (Biber, 1988). The multidimensional analysis identified constellations of language used by providers and patients. Although five linguistic dimensions emerged, one dimension, impersonal information provision, is of unique interest in understanding how providers communicate with patients. Impersonal information provision encompasses the ways in which the provider, using an impersonal tone, discussed the logistics, details, and implications of treatment options. Increased impersonal information provision was associated with patients' decreased anxious preoccupation (beta = -.22, t = -2.82, p = .007), increased treatment plan satisfaction (beta = .36, t = 2.54, p = .012), and increased intention to adhere to treatment recommendations (beta = .34, t = 2.45, p = .018). Findings suggest that specific provider behavior and types of information provided have unique and important effects on patients' health outcomes.

AB - BACKGROUND: Although the levonorgestrel-releasing intrauterine device (LNG-IUD) is one of the most reliable methods of contraception, it is associated with an increased risk of ectopic pregnancy in case of unintended pregnancy. A rare form of ectopic pregnancy is the caesarean scar pregnancy (CSP), with a high risk of serious maternal morbidity, such as uterine rupture, massive haemorrhage and resulting infertility. This report describes the first case of a viable CSP at 13 weeks of gestation in association with the use of a LNG-IUD. Case-presentation: A 36-year-old Caucasian woman was referred to our outpatient clinic because of suspicion of a CSP. The pregnancy was unintended and was diagnosed during replacement of the LNG-IUD after five years. The patient had undergone two caesarean sections in the past. Ultrasound investigation showed an intact pregnancy of approximately 13 weeks of gestation located in the uterine scar. Because of the size of the gestational sac, a laparotomy was performed under general anaesthesia using a Joel-Cohen incision. The procedure was complicated by a total blood loss of 1500 mL, mostly caused by diffuse bleeding from the placental bed. CONCLUSION: Unintended pregnancies in women using a LNG-IUD are frequently ectopic pregnancies with a preponderance to nidate outside the fallopian tube. Therefore, early diagnosis and location of the pregnancy in women using a LNG-IUD is essential. PMID- 29583025 TI - Disgust Toward Sex-Relevant and Sex-Irrelevant Stimuli in Pre-, Early, and Middle Adolescence. AB - For prepubertal youth, sexual stimuli elicit disgust and avoidance, yet in adolescence this avoidance shifts to sexual approach. One explanation could be that disgust declines in adolescence. This project examined whether disgust is indeed lower in adolescence compared to preadolescence, and whether this difference across age groups would be restricted to sex-relevant disgust elicitors. We also examined whether the strength of disgust would depend on familiarity between participant and source. To examine disgust responses in youths, two cross-sectional studies (N = 248, ages six to 17 years) were conducted using scenario-based measurements. Disgust was overall higher in early adolescence than in preadolescence and relatively weak when the source of disgust was a familiar person. Specifically, when parents were the source, sex-relevant disgust was higher in the groups of early and middle adolescents than in the group of preadolescents. Sex-relevant disgust elicited by a stranger or best friend, however, was lower in middle than in early adolescence. The latter is consistent with the view that repeated confrontation with disgusting stimuli might attenuate disgust, which could contribute to healthy sexual functioning. The heightened sex-relevant disgust in middle adolescents when parents were the source might reflect a functional avoidance mechanism of inappropriate sex mates. PMID- 29583026 TI - A new method of onset and offset detection in ensemble singing. AB - This paper presents a novel method combining electrolaryngography and acoustic analysis to detect the onset and offset of phonation as well as the beginning and ending of notes within a sung legato phrase, through the application of a peak picking algorithm, TIMEX. The evaluation of the method applied to a set of singing duo recordings shows an overall performance of 78% within a tolerance window of 50 ms compared with manual annotations performed by three experts. Results seem very promising in light of the state-of-the-art techniques presented at MIREX in 2016 yielding an overall performance of around 60%. The new method was applied to a pilot study with two duets to analyse synchronization between singers during ensemble performances. Results from this investigation demonstrate bidirectional temporal adaptations between performers, and suggest that the precision and consistency of synchronization, and the tendency to precede or lag a co-performer might be affected by visual contact between singers and leader follower relationships. The outcomes of this paper promise to be beneficial for future investigations of synchronization in singing ensembles. PMID- 29583028 TI - Progesterone, progestins and the endometrium in perimenopause and in menopausal hormone therapy. AB - It is well established that unopposed estrogen for hormone therapy in postmenopausal women (MHT) induces a dose-related stimulation of the endometrium associated with an increased risk of hyperplasia and endometrial cancer. Progesterone acts physiologically to counteract the proliferative effects of estradiol during the menstrual cycle. In MHT, progestogens protect the endometrium against the proliferative effects of estrogens in women with a uterus. Recent data suggest that, whereas micronized progesterone is apparently safer for the breast, it could be less efficient than synthetic progestin on the endometrium. An update on progestogen and endometrial safety in MHT is the subject of this review. PMID- 29583027 TI - Enhancer talk. AB - Enhancers are short noncoding segments of DNA (100-1000 bp) that control the temporal and spatial activity of genes in an orientation-independent manner. They can be separated from their target genes by large distances and are thus known as distal regulatory elements. One consequence of the variability in the distance separating enhancers and their target promoters is that it is difficult to determine which elements are involved in the regulation of a particular gene. Moreover, enhancers can be found in clusters in which multiple regulatory elements control expression of the same target gene. However, little is known about how the individual elements contribute to gene expression. Here, we describe how chromatin conformation promotes and constraints enhancer activity. Further, we discuss enhancer clusters and what is known about the contribution of individual elements to the regulation of target genes. Finally, we examine the reliability of different methods used to identify enhancers. PMID- 29583029 TI - Bacterial detection using bacteriophages and gold nanorods by following time dependent changes in Raman spectral signals. AB - This study attemps to develop bacterial detection strategies using bacteriophages and gold nanorods (GNRs) by Raman spectral analysis. Escherichia coli was selected as the target and its specific phage was used as the bioprobe. Target bacteria and phages were propagated/purified by traditional techniques. GNRs were synthesized by using hexadecyltrimethyl ammonium bromide (CTAB) as stabilizer. A two-step detection strategy was applied: Firstly, the target bacteria were interacted with GNRs in suspensions, and then they were dropped onto silica substrates for detection. It was possible to obtain clear surface-enchanced Raman spectroscopy (SERS) peaks of the target bacteria, even without using phages. In the second step, the phage nanoemulsions were droped onto the bacterial-GNRs complexes on those surfaces and time-dependent changes in the Raman spectra were monitored at different time intervals upto 40 min. These results demonstrated that how one can apply phages with plasmonic nanoparticles for detection of pathogenic bacteria very effectively in a quite simple test. PMID- 29583032 TI - Evaluation of natural mandibular shape asymmetry: an approach by using elliptical Fourier analysis. AB - OBJECTIVES: The purpose of this study was to demonstrate that asymmetry is a natural occurring phenomenon in the mandibular shape by using elliptical Fourier analysis. METHODS: 164 digital orthopantomographs from Colombian patients of both sexes aged 18 to 25 years were collected. Curves from left and right hemimandible were digitized. An elliptical Fourier analysis was performed with 20 harmonics. In the general sexual dimorphism a principal component analysis (PCA) and a hotelling T2 from the multivariate warp space were employed. Exploratory analysis of general asymmetry and sexual dimorphism by side was made with a Procrustes Fit. A non-parametric multivariate analysis of variance (MANOVA) was applied to assess differentiation of skeletal classes of each hemimandible, and a Procrustes analysis of variance (ANOVA) was applied to search any relation between skeletal class and side in both sexes. RESULTS: Significant values were found in general asymmetry, general sexual dimorphism, in dimorphism by side (p < 0.0001), asymmetry by sex, and differences between Class I, II, and III (p < 0.005). However, a relation of skeletal classes and side was not found. CONCLUSIONS: The mandibular asymmetry by shape is present in all patients and should not be articulated exclusively to pathological processes, therefore, along with sexual dimorphism and differences between skeletal classes must be taken into account for improving mandibular prediction systems.

Kenneth Baillie, and The Lake Louise AMS Score Consensus Committee. The 2018 Lake Louise Acute Mountain Sickness Score. High Alt Med Biol 19:1-4, 2018.- The Lake Louise Acute Mountain Sickness (AMS) scoring system has been a useful research tool since first published in 1991. Recent studies have shown that disturbed sleep at altitude, one of the five symptoms scored for AMS, is more likely due to altitude hypoxia per se, and is not closely related to AMS. To address this issue, and also to evaluate the Lake Louise AMS score in light of decades of experience, experts in high altitude research undertook to revise the score. We here present an international consensus statement resulting from online discussions and meetings at the International Society of Mountain Medicine World Congress in Bolzano, Italy, in May 2014 and at the International Hypoxia Symposium in Lake Louise, Canada, in February 2015. The consensus group has revised the score to eliminate disturbed sleep as a questionnaire item, and has updated instructions for use of the score. PMID- 29583033 TI - Adult self-image and well-being after testicular cancer: The role of agency and meaning. AB - OBJECTIVE: Cancer during young adulthood can limit the extent to which one adopts an adult self-image. However, the relationship of adult self-image to cancer related adjustment remains unexplored. The current study examines relationships of adult self-image and social/emotional well-being and job-related problems in young testicular cancer survivors. Factors thought to facilitate future-oriented goals (i.e. agency and meaning) are examined as intermediary processes. DESIGN: Testicular cancer survivors (N = 171) between the ages of 18 and 29 completed questionnaire measures of adult self-image, agency, sense of meaning and indicators of adjustment. MAIN OUTCOME MEASURES: Social and emotional well-being were measured by the Functional Assessment of Cancer Therapy-General. Job problems were assessed using the EORTC's testicular cancer supplement (EORTC QLQ TC26). RESULTS: Path model results revealed direct associations of survivors' adult self-image with social (beta = .20, p < .05), but not emotional well-being (beta = .14, p < .01). Both agency and meaning mediated the relationship of adult self-image and well-being indicators. Finally, the relationship between adult self-image and job problems was only significant for those who were employed or in school (beta = -.19, p < .05). OUTCOMES: Assessment of adult self-image might be useful in identifying risk for poor adjustment. Interventions that target agency and meaning might facilitate developmental goals. PMID- 29583030 TI - SAMHD1: Recurring roles in cell cycle, viral restriction, cancer, and innate immunity. AB - Sterile alpha motif and histidine-aspartic acid domain-containing protein 1 (SAMHD1) is a deoxynucleotide triphosphate (dNTP) hydrolase that plays an important role in the homeostatic balance of cellular dNTPs. Its emerging role as an effector of innate immunity is affirmed by mutations in the SAMHD1 gene that cause the severe autoimmune disease, Aicardi-Goutieres syndrome (AGS) and that are linked to cancer. Additionally, SAMHD1 functions as a restriction factor for retroviruses, such as HIV. Here, we review the current biochemical and biological properties of the enzyme including its structure, activity, and regulation by post-translational modifications in the context of its cellular function. We outline open questions regarding the biology of SAMHD1 whose answers will be important for understanding its function as a regulator of cell cycle progression, genomic integrity, and in autoimmunity. PMID- 29583034 TI - Becoming active: more to exercise than weight loss for indigenous men. AB - OBJECTIVE: To understand what motivates sedentary indigenous and ethnic minority men to become more physically active. DESIGN: We use thematic analysis to present data from a qualitative study exploring 23 sedentary indigenous Maori (New Zealand) men's experiences of completing a 12-week exercise intervention to improve their metabolic health. RESULTS: Four themes emerged: The Bros - having fellowship and mutual motivation; Being better informed about exercise; Impacting overall wellbeing; and Disseminating the findings beyond the study Exercise interventions informed by indigenous Maori cultural values and knowledge increased its relevance to their daily lives. The motivation for these indigenous men was more culturally-based external factors than an inherent desire to lose weight. CONCLUSION: Indigenous and minority men in many developed countries have high morbidity and premature mortality related to sedentary lifestyles. The low uptake of physical activities possibly relates to focusing more on outcomes such as weight loss which lacks cultural relevance. When offering health promotion interventions for marginalized populations these findings highlight the importance of culturally tailoring interventions to the unique sources of motivation for each group to increase activity to improve their efficacy.

AB - : Environmental factors during the fetal period may adversely affect reproductive functions in men being born with very low birth weight (VLBW, <1500 g). The objective of this prospective, controlled cohort study was to investigate if VLBW men have an altered reproductive hormone profile compared with men born at term. The study group initially consisted of all VLBW boys live-born between 1 February 1987 and 30 April 1988 in the south-east region of Sweden (n = 47). A control child was chosen born at term, at the same hospital, with the same parity, without malformations, and next in order after each VLBW child who survived the first four weeks (n = 45). The present follow-up was performed when the men were 26-28 years of age and included measurements of serum hormone levels, hair testosterone concentration, and anthropometric data. Also life-style questionnaires were collected from 26 VLBW men and 19 controls. The VLBW group (n = 26) had higher median levels of serum estradiol, 84.5 pmol/L than controls (n = 19), 57.5 pmol/L (p = 0.008). There was no significant correlation between serum estradiol and BMI (r = 0.06, p = 0.74). There were no differences in other hormone levels or the reproductive pattern between the groups. In conclusion, even though there was a statistically significant difference in estradiol levels between the groups, both groups had low normal mean levels of questionable clinical significance. The reproductive pattern was similar in the two groups and in this study being born VLBW does not seem to affect these measured aspects of reproduction.

PMID- 29583036 TI - The ocular involvement did not accompany with the genital ulcer or the gastrointestinal symptoms at the early stage of Behcet's disease. AB - OBJECTIVES: This study aimed to identify patients with high-probability of ocular involvement of Behcet's disease (BD). METHODS: The Japanese Ministry of Health, Labour and Welfare provided dataset of ongoing nationwide BD registration project. A patient who had confirmed BD and who was suspected to have BD was registered. We mainly analyzed newly registered patients who had the data for all demographic and diagnostic parameters regardless of fulfilment of any diagnostic criteria. RESULTS: Among 3213 patients with confirmed or possible BD, 1382 (43.0%) were men and 1831 (57.0%) were women with a median age of 38 years (interquartile range (IQR) 30-49 years). The median duration between onset and registration was 0 year (IQR 0-3). A binomial multivariable logistic regression analysis revealed that being female (odds ratio (OR) 0.63, 95% confidence interval (CI) 0.53-0.75, p < .001), duration since onset (OR 1.33 per 10 years, 95% CI 1.18-1.51, p < .001), genital ulceration (OR 0.28, 95% CI 0.23-0.34, p < .001), and gastrointestinal symptoms (OR 0.36, 95% CI 0.30-0.44, p < .001) were related to the ocular lesion. Analyses based on data of 2800 patients who satisfied International criteria of BD, age-, sex-, duration-based subgroup analyses, analyses targeting iridocyclitis and retino-uveitis, and analysis including patients with missing data confirmed that the four factors were associated with the probability of eye involvement. CONCLUSION: The ocular involvement did not accompany with genital ulcer or gastrointestinal symptoms at the early stage of BD. PMID- 29583037 TI - Detection of atrial fibrillation during pulpal blood flow assessment using Doppler ultrasound: a case report. AB - This report describes the case of a 52-year-old male patient who exhibited suspicious pulsation patterns during pulpal blood flow assessment using Doppler ultrasound. Initially, he was not aware of his cardiovascular problem; however, after referral to a medical clinic, he was diagnosed with atrial fibrillation. The patient was injured in a motor vehicle accident and referred to our clinic for management of multiple traumatized teeth. On clinical examination, several teeth exhibited negative responses to cold and electrical sensibility tests. For accurate diagnosis, pulpal blood flow assessment using a Doppler ultrasound device was performed. During the tests, irregular pulsation patterns were detected, indicating the possibility of a cardiovascular problem. As he denied any history of cardiovascular problems, he was recommended to visit a medical doctor for further evaluation. The following day, he visited a medical clinic, and a 12-lead electrocardiogram was performed. He was ultimately diagnosed with atrial fibrillation with idioventricular rhythm, and was started on anticoagulant medication for prevention of thrombogenesis, which is a possible complication of atrial fibrillation. As presented in this case, Doppler ultrasound can provide useful information, not only about blood flow in the dental pulp, but also about an individual's pulsation rhythm. When a patient presents with irregular pulsation patterns in certain situations, the possibility of cardiovascular problems should be considered. PMID- 29583038 TI - Dishevelled 1, a pivotal positive regulator of the Wnt signalling pathway, mediates 5-fluorouracil resistance in HepG2 cells. AB - Acquired resistance to 5-fluorouracil (5-FU) frequently occurs in patients with hepatocellular carcinoma (HCC), the underlying molecular mechanisms of which are poorly understood. The aim of this study was to identify candidate genes and associated signalling pathways that may play a role in developing drug resistance following repeated 5-FU treatments. In this work, we established 5-FU-resistant cells (HepG2/5-FU) using stepwise increasing concentrations of 5-FU in parental HepG2 cells. Using transcriptome sequencing, we found that the expressions of the Wnt signalling genes, including negative regulators (DKK1, DKK3, ZNRF3, RNF43 and APC2) and positive regulators (FZD10 and DVL1), were significantly downregulated and upregulated in HepG2/5-FU cells, respectively, resulting in increased Wnt signalling. Dishevelled-1 (DVL1) is an essential Wnt signalling pathway component that stabilizes beta-catenin and mediates the Wnt pathway. Silencing DVL1 using siDVL1 or other small molecular inhibitors in HepG2/5-FU cells could restore 5-FU responsiveness via reduced cell proliferation and migration, and increased apoptosis. Moreover, DVL1 was found to be upregulated in BEL-7402/5-FU cells when compared to the parental BEL-7402 cells. Collectively, our results provide the first clue towards understanding the contribution of DVL1-mediated acquired resistance to 5-FU in HepG2/5-FU cells, suggesting a promising therapeutic strategy for liver cancer resistant to 5-FU. PMID- 29583039 TI - Use of proteomic analysis to determine the protein constituents of synovial fluid samples from the stifle joints of dogs with and without osteoarthritis secondary to cranial cruciate ligament rupture. AB - OBJECTIVE To use proteomic analysis to determine the protein constituents of synovial fluid samples from the stifle joints of dogs with and without osteoarthritis secondary to cranial cruciate ligament rupture (CCLR). ANIMALS 12 dogs with clinically normal stifle joints (controls) and 16 dogs with osteoarthritis secondary to CCLR. PROCEDURES A synovial fluid sample was obtained from all dogs. Synovial fluid total protein concentration was determined by the Bradford assay. Proteins were separated by use of a 1-D SDS-PAGE to detect protein bands that differed between dogs with and without osteoarthritis. Those protein bands then underwent trypsin digestion and were analyzed by matrix assisted laser desorption-ionization time-of-flight mass spectrometry, the results of which were compared with a curated protein sequence database for protein identification. One of the most frequently identified proteins, apoprotein (apo) A-I, was then quantified in all synovial fluid samples by use of a competitive-inhibition ELISA. Results were compared between dogs with and without osteoarthritis. RESULTS Median synovial fluid total protein and apo A-I concentrations for dogs with osteoarthritis were significantly greater than those for control dogs. The most abundant proteins identified in the synovial fluid were albumin and apo A-I. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that quantification of synovial fluid total protein and apo A-I concentrations might facilitate diagnosis of osteoarthritis secondary to CCLR in dogs. Further research and validation of synovial fluid apo A-I concentration as a biomarker for osteoarthritis in dogs are necessary before it can be recommended for clinical use. PMID- 29583040 TI - Effects of MK-467 hydrochloride and hyoscine butylbromide on cardiorespiratory and gastrointestinal changes induced by detomidine hydrochloride in horses. AB - OBJECTIVE To compare the effects of MK-467 and hyoscine butylbromide on detomidine hydrochloride-induced cardiorespiratory and gastrointestinal changes in horses. ANIMALS 6 healthy adult horses. PROCEDURES Horses received detomidine hydrochloride (20 MUg/kg, IV), followed 10 minutes later by MK-467 hydrochloride (150 MUg/kg; DET-MK), hyoscine butylbromide (0.2 mg/kg; DET-HYO), or saline (0.9% NaCl) solution (DET-S), IV, in a Latin square design. Heart rate, respiratory rate, rectal temperature, arterial and venous blood pressures, and cardiac output were measured; blood gases and arterial plasma drug concentrations were analyzed; selected cardiopulmonary variables were calculated; and sedation and gastrointestinal borborygmi were scored at predetermined time points. Differences among treatments or within treatments over time were analyzed statistically. RESULTS With DET-MK, detomidine-induced hypertension and bradycardia were reversed shortly after MK-467 injection. Marked tachycardia and hypertension were observed with DET-HYO. Mean heart rate and mean arterial blood pressure differed significantly among all treatments from 15 to 35 and 15 to 40 minutes after detomidine injection, respectively. Cardiac output was greater with DET-MK and DET-HYO than with DET-S 15 minutes after detomidine injection, but left ventricular workload was significantly higher with DET-HYO. Borborygmus score, reduced with all treatments, was most rapidly restored with DET-MK. Sedation scores and pharmacokinetic parameters of detomidine did not differ between DET-S and DET-MK. CONCLUSIONS AND CLINICAL RELEVANCE MK-467 reversed or attenuated cardiovascular and gastrointestinal effects of detomidine without notable adverse effects or alterations in detomidine-induced sedation in horses. Further research is needed to determine whether these advantages are found in clinical patients and to assess whether the drug influences analgesic effects of detomidine. PMID- 29583042 TI - Torsional and axial compressive properties of tibiotarsal bones of red-tailed hawks (Buteo jamaicensis). AB - OBJECTIVE To describe the torsional and axial compressive properties of tibiotarsal bones of red-tailed hawks (Buteo jamaicensis). SAMPLE 16 cadaveric tibiotarsal bones from 8 red-tailed hawks. PROCEDURES 1 tibiotarsal bone from each bird was randomly assigned to be tested in torsion, and the contralateral bone was tested in axial compression. Intact bones were monotonically loaded in either torsion (n = 8) or axial compression (8) to failure. Mechanical variables were derived from load-deformation curves. Fracture configurations were described. Effects of sex, limb side, and bone dimensions on mechanical properties were assessed with a mixed-model ANOVA. Correlations between equivalent torsional and compressive properties were determined. RESULTS Limb side and bone dimensions were not associated with any mechanical property. During compression tests, mean ultimate cumulative energy and postyield energy for female bones were significantly greater than those for male bones. All 8 bones developed a spiral diaphyseal fracture and a metaphyseal fissure or fracture during torsional tests. During compression tests, all bones developed a crushed metaphysis and a fissure or comminuted fracture of the diaphysis. Positive correlations were apparent between most yield and ultimate torsional and compressive properties. CONCLUSIONS AND CLINICAL RELEVANCE The torsional and axial compressive properties of tibiotarsal bones described in this study can be used as a reference for investigations into fixation methods for tibiotarsal fractures in red-tailed hawks. Although the comminuted and spiral diaphyseal fractures induced in this study were consistent with those observed in clinical practice, the metaphyseal disruption observed was not and warrants further research. PMID- 29583043 TI - Effect of oral administration of robenacoxib on inhibition of paracentesis induced blood-aqueous barrier breakdown in healthy cats. AB - OBJECTIVE To determine the effect of oral administration of robenacoxib on inhibition of anterior chamber paracentesis (ACP)-induced breakdown of the blood aqueous barrier (BAB) and assess whether robenacoxib can cross an intact BAB in healthy cats. ANIMALS 12 healthy adult domestic shorthair cats. PROCEDURES Cats received robenacoxib (6-mg tablet in a treat, PO; n = 6) or a control treatment (treat without any drug, PO; 6) once daily for 3 days, beginning 1 day before ACP. One eye of each cat served as an untreated control, whereas the other underwent ACP, during which a 30-gauge needle was used to aspirate 100 MUL of aqueous humor for determination of robenacoxib concentration. Both eyes of each cat underwent anterior chamber fluorophotometry at 0 (immediately before), 6, 24, and 48 hours after ACP. Fluorescein concentration and percentage fluorescein increase were used to assess extent of ACP-induced BAB breakdown and compared between cats that did and did not receive robenacoxib. RESULTS Extent of BAB breakdown induced by ACP did not differ significantly between cats that did and did not receive robenacoxib. Low concentrations of robenacoxib were detected in the aqueous humor (mean, 5.32 ng/mL; range, 0.9 to 16 ng/mL) for 5 of the 6 cats that received the drug. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that oral administration of robenacoxib did not significantly decrease extent of BAB breakdown in healthy cats. Detection of low robenacoxib concentrations in the aqueous humor for most treated cats indicated that the drug can cross an intact BAB. PMID- 29583044 TI - Gross and histologic evaluation of effects of photobiomodulation, silver sulfadiazine, and a topical antimicrobial product on experimentally induced full thickness skin wounds in green iguanas (Iguana iguana). AB - OBJECTIVE To assess effects of photobiomodulation, silver sulfadiazine, and a topical antimicrobial product for the treatment of experimentally induced full thickness skin wounds in green iguanas (Iguana iguana). ANIMALS 16 healthy subadult green iguanas. PROCEDURES Iguanas were anesthetized, and three 5-mm cutaneous biopsy specimens were obtained from each iguana (day 0). Iguanas were randomly assigned to 2 treatment groups, each of which had a control treatment. Wounds in the topical treatment group received silver sulfadiazine, a topical antimicrobial product, or no treatment. Wounds in the laser treatment group received treatment with a class 4 laser at 5 or 10 J/cm2 or no treatment. Wound measurements were obtained daily for 14 days. Iguanas were euthanized, and treatment sites were evaluated microscopically to detect ulceration, bacterial contamination, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity. RESULTS On day 14, wounds treated with a laser at 10 J/cm2 were significantly smaller than those treated with silver sulfadiazine, but there were no other significant differences among treatments. Histologically, there were no significant differences in ulceration, bacterial infection, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity among treatments. CONCLUSIONS AND CLINICAL RELEVANCE Photobiomodulation at 10 J/cm2 appeared to be a safe treatment that was tolerated well by green iguanas, but it did not result in substantial improvement in histologic evidence of wound healing, compared with results for other treatments or no treatment. PMID- 29583045 TI - Effects of short-term anti-inflammatory glucocorticoid treatment on clinicopathologic, echocardiographic, and hemodynamic variables in systemically healthy dogs. AB - OBJECTIVE To investigate mechanisms by which anti-inflammatory doses of orally administered intermediate-acting glucocorticoids (prednisone) could predispose dogs to progression of heart disease or congestive heart failure. ANIMALS 11 client-owned dogs with allergic dermatitis and 11 matched healthy control dogs. PROCEDURES Clinicopathologic, echocardiographic, and hemodynamic variables were measured. Dogs with allergic dermatitis then received prednisone (1 mg/kg, PO) once daily for 14 consecutive days beginning on day 0 (baseline), followed by a tapering and washout period; control dogs received no treatment. Measurements were repeated on days 7, 14, and 35. Linear mixed modeling was used to compare changes in variables across measurement points and between dog groups. RESULTS Prednisone administration caused no significant changes in serum sodium or potassium concentration, blood glucose concentration, or target echocardiographic variables. The change from baseline in systolic arterial blood pressure at day 7 was significantly greater in prednisone-treated dogs than in control dogs. Expected changes in hematologic and serum biochemical values with prednisone administration (neutrophilia, eosinopenia, isosthenuria, and high serum alkaline phosphatase and alanine aminotransferase activities) also occurred in the prednisone-treated dogs. CONCLUSIONS AND CLINICAL RELEVANCE Findings suggested that anti-inflammatory doses of orally administered glucocorticoids have the potential to adversely impact cardiac function in dogs by causing an increase in blood pressure and thus increased cardiac afterload. PMID- 29583046 TI - Quantitative analysis of brain perfusion parameters in dogs with idiopathic epilepsy by use of magnetic resonance imaging. AB - OBJECTIVE To quantitatively analyze brain perfusion parameters in dogs with idiopathic epilepsy (IE) by use of MRI and to compare those findings with brain perfusion parameters for healthy dogs. ANIMALS 12 client-owned dogs with IE. PROCEDURES For each dog, standard MRI and perfusion-weighted imaging (before and after injection of gadoteric acid contrast medium) sequences of the brain were obtained during the interictal period by means of the same protocol used in a comparable study of healthy dogs. Time of contrast medium arrival, time to peak contrast enhancement, mean contrast transit time, and cerebral blood flow were calculated for the caudate nucleus, thalamus, piriform lobe, hippocampus, semioval center, and temporal cerebral cortex. Parameters for each structure were compared between dogs with IE and healthy dogs. RESULTS Dogs with IE had a significantly greater mean time of contrast arrival and lower mean cerebral blood flow than healthy dogs. Differences in cerebral blood flow between dogs with IE and healthy dogs were most pronounced in the piriform lobe, thalamus, and temporal cerebral cortex. The mean contrast transit time did not differ between dogs with IE and healthy dogs. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that, compared with healthy dogs, dogs with IE have decreased blood perfusion of the brain. Findings of this study can be used as a basis for further research into functional changes within the brains of epileptic dogs during the interictal phase. PMID- 29583047 TI - Phagocytosis, bacterial killing, and cytokine activation of circulating blood neutrophils in horses with severe equine asthma and control horses. AB - OBJECTIVE To evaluate in vitro phagocytosis and bactericidal activity of circulating blood neutrophils in horses with severe equine asthma and control horses and to determine whether circulating blood neutrophils in horses with severe equine asthma have an increase in expression of the proinflammatory cytokine tumor necrosis factor (TNF)-alpha and the chemokine interleukin (IL)-8 and a decrease in expression of the anti-inflammatory cytokine IL-10 in response to bacteria. ANIMALS 6 horses with severe equine asthma and 6 control horses. PROCEDURES Circulating blood neutrophils were isolated from horses with severe equine asthma and control horses. Phagocytosis was evaluated by use of flow cytometry. Bactericidal activity of circulating blood neutrophils was assessed by use of Streptococcus equi and Streptococcus zooepidemicus as targets, whereas the cytokine mRNA response was assessed by use of a quantitative PCR assay. RESULTS Circulating blood neutrophils from horses with severe equine asthma had significantly lower bactericidal activity toward S zooepidemicus but not toward S equi, compared with results for control horses. Phagocytosis and mRNA expression of TNF-alpha, IL-8, and IL-10 were not different between groups. CONCLUSIONS AND CLINCAL RELEVANCE Impairment of bactericidal activity of circulating blood neutrophils in horses with severe equine asthma could contribute to an increased susceptibility to infections. PMID- 29583048 TI - Pharmacokinetics and pharmacodynamics after oral administration of tapentadol hydrochloride in dogs. AB - OBJECTIVE To evaluate pharmacokinetic and pharmacodynamic characteristics of 3 doses of tapentadol hydrochloride orally administered in dogs. ANIMALS 6 healthy adult mixed-breed dogs. PROCEDURES In a prospective, randomized crossover study, dogs were assigned to receive each of 3 doses of tapentadol (10, 20, and 30 mg/kg, PO); there was a 1-week washout period between subsequent administrations. Plasma concentrations and physiologic variables were measured for 24 hours. Samples were analyzed by use of high-performance liquid chromatography-tandem mass spectrometry. RESULTS Tapentadol was rapidly absorbed after oral administration. Mean maximum plasma concentrations after 10, 20, and 30 mg/kg were 10.2, 19.7, and 31 ng/mL, respectively. Geometric mean plasma half-life of the terminal phase after tapentadol administration at 10, 20, and 30 mg/kg was 3.5 hours (range, 2.7 to 4.5 hours), 3.7 hours (range, 3.1 to 4.0 hours), and 3.7 hours (range, 2.8 to 6.5 hours), respectively. Tapentadol and its 3 quantified metabolites (tapentadol sulfate, tapentadol-O-glucuronide, and desmethyltapentadol) were detected in all dogs and constituted 0.16%, 2.8%, 97%, and 0.04% of the total area under the concentration-time curve (AUC), respectively. Plasma AUCs for tapentadol, tapentadol sulfate, and tapentadol-O glucuronide increased in a dose-dependent manner. Desmethyltapentadol AUC did not increase in a linear manner at the 30-mg/kg dose. Sedation scores and heart and respiratory rates were not significantly affected by dose or time after administration. CONCLUSIONS AND CLINICAL RELEVANCE Oral administration of tapentadol was tolerated well, and the drug was rapidly absorbed. Adverse events were not apparent in any dogs at any doses in this study. PMID- 29583049 TI - Role of toll-like receptor 4 and caspase-3, -8, and -9 in lipopolysaccharide induced delay of apoptosis in equine neutrophils. AB - OBJECTIVE To evaluate the effect of lipopolysaccharide (LPS) on apoptosis of equine neutrophils in vitro. SAMPLE Venous blood samples from 40 adult horses. PROCEDURES Neutrophils were isolated from blood samples and cultured with or without LPS from Escherichia coli O55:B5 for 12 or 24 hours. Neutrophil apoptosis was assessed by use of cytologic examination, annexin V and propidium iodide staining quantified with flow cytometry, coincubation with inducers of intrinsic and extrinsic apoptosis or a toll-like receptor (TLR) 4 inhibitor, and measurement of caspase-3, -8, and -9 activities. RESULTS Treatment with LPS resulted in a significant delay in apoptosis after incubation for 12 and 24 hours (neutrophils from blood samples of 40 horses). There was a significant correlation between increases in LPS dose and decreases in apoptosis after incubation for 24 hours (3 experiments, each of which involved neutrophils obtained from the same 3 horses at 3 separate times). Caspase-9 activity, but not caspase-3 or -8 activity, was significantly reduced in LPS-treated neutrophils after incubation for 12 hours (neutrophils from blood samples of 17 horses). Treatment with a TLR4 inhibitor or intrinsic and extrinsic inducers of apoptosis prevented LPS-delayed apoptosis. CONCLUSIONS AND CLINICAL RELEVANCE LPS treatment delayed apoptosis of equine neutrophils in vitro for up to 24 hours in a dose dependent manner by alteration of the intrinsic pathway of apoptosis and was dependent on TLR4 signaling. Increased neutrophil life span may contribute to the development of a systemic inflammatory response syndrome in endotoxemic horses. PMID- 29583050 TI - Quantification of right ventricular volume measured by use of real-time three dimensional echocardiography and electrocardiography-gated 64-slice multidetector computed tomography in healthy dogs. AB - OBJECTIVE To evaluate accuracy of quantification of right ventricle volume (RVV) by use of 3-D echocardiography (3DE) and ECG-gated multidetector CT (MDCT). ANIMALS 6 healthy hound-cross dogs. PROCEDURES ECG-gated MDCT and complete 3DE examinations were performed on each dog. Right ventricular end-diastolic volumes (EDVs), end-systolic volumes (ESVs), stroke volume (SV), and ejection fraction (EF) were measured for 3DE and MDCT data sets by use of software specific for RVV quantification. Correlation and level of agreement between methods were determined. Intraobserver and interobserver variability were assessed for 3DE. RESULTS No significant differences were detected between SV and EF obtained with MDCT and 3DE. Significant differences were detected between right ventricular EDV and ESV obtained with MDCT and 3DE. No significant difference in heart rate was detected between methods. The correlation between MDCT and 3DE was very good (r = 0.87) for EDV and ESV, moderate (r = 0.60) for EF, and poor (r = 0.31) for SV. Bland-Altman analysis revealed a systematic underestimation of RVV derived by use of 3DE, compared with the RVV derived by use of MDCT (mean bias, 15 and 10.3 mL for EDV and ESV, respectively). Intraobserver (EDV, 12%; ESV, 18%) and interobserver (EDV, 14%; ESV, 11%) variability were acceptable for 3DE. CONCLUSIONS AND CLINICAL RELEVANCE There was substantial variance for RVV measured by use of 3DE in healthy dogs and a significant underestimation of volumes, compared with results for MDCT, despite the fact there were no significant differences in SV and EF. PMID- 29583052 TI - Associations between dialysate sodium concentration and plasma sodium concentration of dogs receiving intermittent hemodialysis treatments. AB - OBJECTIVE To compare dialysate sodium concentration and patient plasma sodium concentration of dogs during intermittent hemodialysis treatments. SAMPLE 211 intermittent hemodialysis treatments performed on 40 client-owned dogs for the management of dialysis-dependent uremia. PROCEDURES Medical records were reviewed to determine the plasma sodium concentration of each dog before and after routine hemodialysis treatments. Associations between detected changes in plasma sodium concentration and dialysate sodium concentration were evaluated by use of Spearman rank correlations and linear regression analysis. RESULTS Significant linear correlations were found between the dialysate sodium concentration and patient sodium concentration. The starting dialysate-to-patient sodium gradient was associated with the strongest correlation to the change in patient sodium concentration at the end of the dialysis session. Modest correlations existed between the dialysate sodium concentration and postdialysis patient sodium concentration as well as between the predialysis dialysate-to-patient sodium gradient and postdialysis dialysate-to-patient sodium gradient. CONCLUSIONS AND CLINICAL RELEVANCE The dialysate sodium concentration was correlated with the patient sodium concentration in dogs, and the dialysate-to-patient sodium gradient could be used to further refine this association to predict the postdialysis patient sodium concentration and potentially manage dysnatremia during hemodialysis. Prospective studies should be performed to determine how these associations can be used to correct aberrations as well as to avoid unwanted alterations in patient sodium concentrations.

PMID- 29583054 TI - Sequencing of disease-modifying therapies for relapsing-remitting multiple sclerosis: a theoretical approach to optimizing treatment. AB - Multiple sclerosis (MS) is a chronic disease which usually begins in young adulthood and is a lifelong condition. Individuals with MS experience physical and cognitive disability resulting from inflammation and demyelination in the central nervous system. Over the past decade, several disease-modifying therapies (DMTs) have been approved for the management of relapsing-remitting MS (RRMS), which is the most prevalent phenotype. The chronic nature of the disease and the multiple treatment options make benefit-risk-based sequencing of therapy essential to ensure optimal care. The efficacy and short- and long-term risks of treatment differ for each DMT due to their different mechanism of action on the immune system. While transitioning between DMTs, in addition to immune system effects, factors such as age, disease duration and severity, disability status, monitoring requirements, preference for the route of administration, and family planning play an important role. Determining a treatment strategy is therefore challenging as it requires careful consideration of the differences in efficacy, safety and tolerability, while at the same time minimizing risks of immune modulation. In this review, we discuss a sequencing approach for treating RRMS, with importance given to the long-term risks and individual preference when devising a treatment plan. Evidence-based strategies to counter breakthrough disease are also addressed. PMID- 29583055 TI - Preparation of mesoporous silica microparticles by sol-gel/emulsion route for protein release. AB - Encapsulation of therapeutic proteins into particles from appropriate material can improve both stability and delivery of the drugs, and the obtained particles can serve as a platform for development of their new oral formulations. The main goal of this work was development of sol-gel/emulsion method for preparation of silica microcapsules capable of controlled release of encapsulated protein without loss of its native structure. For this purpose, the reported in literature direct sol-gel/W/O/W emulsion method of protein encapsulation was used with some modifications, because the original method did not allow to prepare silica microcapsules capable for protein release. The particles were synthesized using sodium silicate and tetraethoxysilane as silica precursors and different compositions of oil phase. In vitro kinetics of bovine serum albumin (BSA) release in buffer (pH 7.4) was studied by Fourier transform infrared (FTIR) and fluorescence spectrometry, respectively. Structural state of encapsulated BSA and after release was evaluated. It was found that the synthesis conditions influenced substantially the porous structure of the unloaded silica particles, release properties of the BSA-loaded silica particles and structural state of the encapsulated and released protein. The modified synthesis conditions made it possible to obtain the silica particles capable of controlled release of the protein during a week without loss of the protein native structure. PMID- 29583056 TI - Effect of an educational program based on cognitive behavioral techniques on fear of childbirth and the birth process. AB - OBJECTIVE: This study determined the effect of an educational program based on cognitive behavioral techniques (CBT) provided for pregnant women to address their fear of childbirth. METHODS: This study was conducted experimentally using pretest-posttest and a control group. A total of 111 Turkish pregnant women were recruited with 52 in the intervention group and 59 in the control group. The intervention group attended the educational program on coping with childbirth fears based on CBT, which took 3 weeks over six sessions. The Wijma Delivery Expectancy/Experience Questionnaire, version-A (W-DEQ-A) was administered to both groups as the posttest. The researchers monitored the pregnant women's labor and delivery and the State Anxiety Inventory (SAI), Numeric Pain Rating Scale (NPRS) and Birth Process Evaluation Form were completed. RESULTS: The post-education W DEQ-A score was 63.5 in the control group and 39.4 in the intervention group (p < .001). Their labor pain was lower, the second stage of labor was shorter and birth was more satisfactory for the intervention group than for the control group (p < .05). The CBT-based educational program and pain severity during childbirth were the significant predictors of satisfaction with childbirth (beta = 0.354; beta = -0.324, respectively; p < .05 for all). CONCLUSIONS: The CBT-based educational program on coping with childbirth fears reduced pregnant women's fear of childbirth and positively affected their birth experience. PMID- 29583057 TI - Remote Patient Monitoring and Clinical Outcomes for Postdischarge Patients with Type 2 Diabetes. AB - The objective of this study was to evaluate changes in clinical outcomes for patients with type 2 diabetes (T2D) after a 3-month remote patient monitoring (RPM) program, and examine the relationship between hemoglobin A1c (HbA1c) outcomes and participant characteristics. The study sample included 955 patients with T2D who were admitted to an urban Midwestern medical center for any reason from 2014 to 2017, and used RPM for 3 months after discharge. Clinical outcomes included HbA1c, weight, body mass index (BMI), and patient activation scores. Logistic regression was used to estimate the likelihood of having a postintervention HbA1c <9% by patient characteristics, among those who had baseline HbA1c >9%. Most patients experienced decreases in HbA1c (67%) and BMI (58%), and increases in patient activation scores (67%) (P < 0.001 in all 3 cases) at the end of RPM. Logistic regression analyses revealed that among patients who had HbA1c >9% at baseline, men (odds ratio [OR] = 3.72; 95% confidence interval [CI], 1.43-9.64), those who had increased patient activation scores after intervention (OR = 1.05; 95% CI, 1.01-1.09), those who had higher baseline patient activation scores, and those who had a greater number of biometric data uploads during the intervention (OR = 1.02; 95% CI, 1.00-1.04) were more likely to have reduced their HbA1c to <9% at the end of RPM. RPM for postdischarge patients with T2D might be a promising approach for HbA1c control with increased patient engagement. Future studies with study designs that include a control group should provide more robust evidence.

AB - The aim of this study was to evaluate if the stability of dental implants varies between dental implants placed by piezosurgery compared with those placed by conventional drilling. An electronic search in MEDLINE, SCOPUS, and the Cochrane Library was undertaken until August 2016 and was supplemented by manual searches and by unpublished studies at OpenGray. Only randomized controlled clinical trials that reported implant site preparation with piezosurgery and with conventional drilling were considered eligible for inclusion in this review. Meta analyses were performed to evaluate the impact of piezosurgery on implant stability. Of 456 references electronically retrieved, 3 were included in the qualitative analysis and quantitative synthesis. The pooled estimates suggest that there is no significant difference between piezosurgery and conventional drilling at baseline (weighted mean differences [WMD]: 2.20; 95% confidence interval [CI]: -5.09, 9.49; P = .55). At 90 days, the pooled estimates revealed a statistically significant difference (WMD: 3.63; 95% CI: 0.58, 6.67, P = .02) favoring piezosurgery. Implant stability may be slightly improved when osteotomy is performed by a piezoelectric device. More randomized controlled clinical trials are needed to confirm these findings.

AB - OBJECTIVE: Anemia is associated with increased cardiovascular morbidity in the general population. Anemia is common during pregnancy. We examined the association between anemia at the very early postpartum period and long-term atherosclerotic-related morbidity. PATIENTS AND METHODS: A retrospective study including women who gave birth between 1988 and 2013 was conducted. The women were divided into two groups according to hemoglobin (Hb) value on the first day after delivery: Hb <10 g/dL and Hb >=10 g/dL. We examined the rates of hospitalization due to atherosclerotic-related morbidity, which were classified into minor and major events. The follow-up period was from the index birth until either hospitalization or the end of study period. Survival estimates were calculated by Kaplan-Meier survival analysis. Cox proportional hazards models were used to evaluate whether Hb <10 gr/dL is an independent risk factor for long term atherosclerotic events. RESULTS: The study population included 30,088 (37.40%) women with Hb <10 g/dL and 50,354 (63%) women with Hb >=10 g/dL at the index birth. The hospitalization incidence density was higher in the Hb <10 g/dL group versus the Hb >=10 g/dL group, for total atherosclerotic- related hospitalizations (4.35 vs. 3.76, p < 0.001), and hospitalization for major events (1.83 vs. 1.51, p < 0.001) and minor events (2.60 vs. 2.31, p < 0.001). In Cox proportional hazards models, it was demonstrated that Hb <10 g/dL was independently associated with total hospitalizations (HR 1.13; CI: 1.04-1.24 p = 0.004) and hospitalizations for major events (HR 1.16; CI: 1.01-1.34 p = 0.034) Conclusions: Hb <10 g/dL at the very early postpartum period might be a marker for long-term atherosclerotic-related morbidity.

PMID- 29583060 TI - PAPep Inhibits Secretion of Poly(I:C)-Induced Inflammatory Cytokines and ICAM-1 Expression in Corneal Fibroblasts by Suppressing the NF-kappaB/p38 Pathway. AB - PURPOSE: To assess the anti-inflammatory effect and mechanism of a novel peptide, PAPep, in poly(I:C)-stimulated corneal fibroblasts. METHODS: Corneal fibroblasts were treated with poly(I:C) to elicit inflammation. Real-time polymerase chain reaction (PCR) and ELISA were used to measure the mRNA and protein levels of interleukin (IL)-6, monocyte chemotactic factor (MCP)-1, and interferon gamma (IFN-gamma). Real-time PCR, immunofluorescence, and immunoblot were performed to determine ICAM-1 expression. Translocation of NF-kappaB p65 was observed by immunofluorescence. Phosphorylation of IkappaBalpha, NF-kappaB, and mitogen activated protein kinase (MAPK) (p38, JNK and ERK) were detected by western blot. RESULTS: The results showed that PAPep effectively decreased mRNA and protein expression of IL-6, MCP-1, and IFN-gamma in corneal fibroblasts exposed to poly(I:C). In addition, PAPep reduced mRNA and protein levels of ICAM-1. The NF kappaB and MAPK(p38) pathway were inhibited by PAPep treatment, as indicated by suppression of p65 nuclear translocation, and IkappaBalpha, NF-kappaB, and p38 activation. PAPep showed no effect on JNK or ERK activity. CONCLUSIONS: PAPep attenuates the expression of inflammatory cytokines and ICAM-1 in corneal fibroblasts induced by poly(I:C) through blocking the NF-kappaB and MAPK(p38) pathway. PAPep may be considered a promising therapeutic agent for treating viral keratitis.

AB - INTRODUCTION: Process evaluation is an important tool in quality improvement efforts. This article illustrates how a systematic and continuous evaluation process can be used to improve the quality of faculty career development programs by using the University of Minnesota's Building Interdisciplinary Research Careers in Women's Health (BIRCWH) K12 program as an exemplar. METHODS: Data from a rigorous process evaluation incorporating quantitative and qualitative measurements were analyzed and reviewed by the BIRCWH program leadership on a regular basis. RESULTS: Examples are provided of how this evaluation model and processes were used to improve many aspects of the program, thereby improving scholar, mentor, and advisory committee members' satisfaction and scholar outcomes. CONCLUSIONS: A rigorous evaluation plan can increase the effectiveness and impact of a research career development plan. PMID- 29583063 TI - Double Pass 595 nm Pulsed Dye Laser Does Not Enhance the Efficacy of Port Wine Stains Compared with Single Pass: A Randomized Comparison with Histological Examination. AB - OBJECTIVE: To compare the efficacy and safety of double-pass pulsed dye laser (DWL) and single-pass PDL (SWL) in treating virgin port wine stain (PWS). BACKGROUND: The increase in the extent of vascular damage attributed to the use of double-pass techniques for PWS remains inconclusive. A prospective, side-by side comparison with a histological study for virgin PWS is still lacking. MATERIALS AND METHODS: Twenty-one patients (11 flat PWS, 10 hypertrophic PWS) with untreated PWS underwent 3 treatments at 2-month intervals. Each PWS was divided into three treatment sites: SWL, DWL, and untreated control. Chromametric and visual evaluation of the efficacy and evaluation of side effects were conducted 3 months after final treatment. Biopsies were taken at the treated sites immediately posttreatment. RESULTS: Chromametric and visual evaluation suggested that DWL sites showed no significant improvement compared with SWL (p > 0.05) in treating PWS. The mean depth of photothermal damage to the vessels was limited to a maximum of 0.36-0.41 mm in both SWL and DWL sides. Permanent side effects were not observed in any patients. CONCLUSIONS: Double-pass PDL does not enhance PWS clearance. To improve the clearance of PWS lesions, either the depth of laser penetration should be increased or greater photothermal damage to vessels should be generated. PMID- 29583064 TI - Prescribing Bioidentical Menopausal Hormone Therapy: A Survey of Physician Views and Practices. AB - BACKGROUND: It is estimated that 1-2.5 million U.S. women use compounded bioidentical menopausal hormone therapy (MHT). However, the proportion of American physicians prescribing compounded bioidentical hormones remains unknown. This study aims to evaluate obstetrician-gynecologists' (OB/GYNs) and family medicine physicians' decisions reflected in prescribing practices of MHT in Kansas, and level of agreement with the American College of Obstetricians and Gynecologists (ACOG) recommendations. METHODS: An Internet-based 38-item survey was electronically disseminated to OB/GYNs and family medicine physicians identified through the Kansas State Board of Healing Arts licensure list. RESULTS: Out of 1349 physicians contacted, 164 (12.2%) responded to the survey. There were 128 (9.5%) responses included in the final analysis. In the past year, 96.1% (123/128) of respondents prescribed conventional MHT, 93.0% (119/128) prescribed Food and Drug Administration (FDA)-approved bioidentical MHT, and 66.1% (84/127) prescribed compounded bioidentical MHT. Of factors influencing MHT prescribing practices, FDA regulation was not important to 16.7% (21/126) of physicians, whereas customization was important to 68.5% (87/127). There was a significant difference between specialties, 37.7% of OB/GYNs compared with 56.9% of family medicine physicians, regarding the ACOG statement that "patients should be counseled that conventional MHT is more appropriate than compounded preparations" (p = 0.031). Respondents disagreed with ACOG regarding the statements that "the practice of compounding makes it difficult to identify the active agent responsible for various effects" (41.0% of OB/GYNs and 34.8% of family medicine physicians) and "the practice of custom blending commercially available drug products lacks both a strong biological rationale and medical evidence for effectiveness" (36.1% of OB/GYNs and 37.9% of family medicine physicians). CONCLUSIONS: Prescribing practices for MHT vary between specialties. This study identifies a meaningful level of disagreement with ACOG recommendations regarding prescription of compounded rather than FDA-approved MHT. Further research is needed to better understand this level of discordance. PMID- 29583065 TI - Lack of Impact of the 2009 USPSTF Guidelines on Rates of Mammography Screening. AB - BACKGROUND: In November 2009, the United States Preventive Services Task Force (USPSTF) changed their mammography screening guidelines from recommending a screen every 1-2 years for women older than 40 years. The revised guideline recommends against regular screening for women aged 40-49 and recommends biennial screening for women aged 50-74. RESEARCH DESIGN: We used autoregressive integrated moving-average (ARIMA) time series modeling to estimate the effect of the USPSTF 2009 guidelines on trends in screening rates. Enrollment and encounter files from the PharMetrics LifeLink+ commercial insurance claims database, years 2006-2014, were linked to determine monthly screening rates. The main outcome measure was mammography screening rates per 1,000 commercially insured women aged 40-49 or aged 50-64. RESULTS: The study sample included 493,347 women aged 40-49 years with at least 1 month of eligibility and 658,052 women aged 50-64 years with at least 1 month of eligibility. There were 1,305,375 total screening mammograms from 2007 to 2014. Average monthly mammography screening rates from 2007 to 2014 were 40.4 per 1,000 women aged 40-49 and 54.8 per 1,000 women aged 50-64. There was a temporary decline in monthly screening rates of 11.8% and 11.2% for the 40-49 and 50-64 age groups, respectively, in the 2-month period after the guideline change (January and February 2010), but the rates quickly returned to pre-USPSTF trend levels afterward. CONCLUSION: Implementation of the USPSTF 2009 guidelines was not associated with a persistent long-term change in mammography screening rates over the next 5 years, despite a temporary decline of 2 months immediately following the guidelines. PMID- 29583066 TI - Naturally Occurring Hair Growth Peptide: Water-Soluble Chicken Egg Yolk Peptides Stimulate Hair Growth Through Induction of Vascular Endothelial Growth Factor Production. AB - Alopecia is divided into two categories: androgenic alopecia and nonandrogenic alopecia. An androgen-dependent abnormality of biological functions causes alopecia in males, but the role of androgens is not yet elucidated in female pattern hair loss (FPHL). Modulation of androgenic activity is not effective in certain kinds of androgenic alopecia in females, as well as in cases of nonandrogenic alopecia in males and females. The hair growth drug, minoxidil, stimulates vascular endothelial growth factor (VEGF) production as well as vascularization and hair growth in females. Yet, because minoxidil has side effects with long-term use, a safe alternative hair growth agent is needed. Whereas hair develops after birth in mammalian species, hair mostly grows in a precocial bird, in the chicken, between hatching days 14 and 15. Therefore, we hypothesized that the chicken egg contains a key hair growth factor. In this study, we demonstrated that water-soluble peptides derived from the egg yolk stimulate VEGF production and human hair follicle dermal papilla cell growth. We also found that these peptides enhance murine hair growth and improve hair growth in FPHL. Finally, we characterized that water-soluble egg yolk peptides induce VEGF expression through insulin growth factor-1 receptor activation-induced hypoxia-inducible factor-1alpha transcription pathway. We have given the name "hair growth peptide (HGP)" to this water-soluble egg yolk peptide. PMID- 29583067 TI - Neurofibromatous neuropathy: An ultrastructural study. AB - Plexiform neurofibroma is pathognomonic of neurofibromatosis 1 (NF1). An NF1 associated peripheral neuropathy has been described in a small minority of NF1 patients but its histopathological features are poorly characterized. We report the case of a 46-year-old woman presenting with bilateral supraclavicular painful masses without other stigmata of NF1. MRI showed bilateral plexiform lesions extending from cervical roots to the elbows. Nerve conduction studies documented a sensory motor polyneuropathy. Morphometric analysis of sural nerve biopsy showed a preferential loss of large-caliber myelinated fibers with a g ratio of 0.515, and the presence of regeneration clusters. By electron microscopy, marked and diffuse endoneurial fibrosis with an altered relationship between Schwann cells (SC) and collagen fibrils was observed. Moreover both myelinating and non myelinating SC were characterized by the presence of various cell degradation products. These changes suggest that, in neurofibromatous neuropathy, a widespread axonal atrophy and degeneration take place independently on the presence of tumoral infiltration, possibly due to an impairment in SC-axon cross talk. In this case, the coexistence of plexiform neurofibromas with a peripheral neuropathy strongly suggests a diagnosis of NF1 even without fulfillment of clinical criteria. We propose that in the presence of plexiform neurofibromas, electrophysiological studies should be performed also in asymptomatic patients, in order to detect the existence of a subclinical neuropathy. PMID- 29583069 TI - Associations Among Sleep, Body Mass Index, Waist Circumference, and Risk of Type 2 Diabetes Among U.S. Childbearing-Age Women: National Health and Nutrition Examination Survey. AB - BACKGROUND: Women of childbearing age (18-44 years) present an important group for understanding sleep, but few studies have focused on this population. No study has investigated the associations among sleep, overweight/obesity, and risk of type 2 diabetes among childbearing-age women in the National Health and Nutrition Examination Survey (NHANES). METHODS: Data were from NHANES, 2005-2008. The study population consisted of 18-44 year old women. Pregnant women and those diagnosed with sleep disorders were excluded. Sleep duration and quality were self-reported. Body mass index (BMI), waist circumference (WC) measurements, and a 2-hour 75 g oral glucose tolerance test (OGTT) were performed by trained NHANES staff. An unadjusted linear regression analysis; a second adjusted for demographics only (partially adjusted model); and a third adjusted for demographics and variables associated with overweight/obesity and diabetes (fully adjusted model) were computed to assess associations among sleep duration/quality and BMI, WC, and 2-hour OGTT. RESULTS: Total sample consisted of 2388 childbearing-age women. Only sleep duration was significantly associated with BMI and WC in the unadjusted and partially adjusted models, but was no longer significant in the fully adjusted model. Neither sleep duration nor quality was significantly associated with 2-hour OGTT in any of the models. CONCLUSIONS: Targeting sleep duration and sleep quality alone would not likely contribute to significantly lower BMI, WC, or risk of type 2 diabetes in US childbearing-age women. Additional studies, especially longitudinal ones using objective measures of sleep, are needed to confirm these findings. PMID- 29583068 TI - HLPI-Ensemble: Prediction of human lncRNA-protein interactions based on ensemble strategy. AB - LncRNA plays an important role in many biological and disease progression by binding to related proteins. However, the experimental methods for studying lncRNA-protein interactions are time-consuming and expensive. Although there are a few models designed to predict the interactions of ncRNA-protein, they all have some common drawbacks that limit their predictive performance. In this study, we present a model called HLPI-Ensemble designed specifically for human lncRNA protein interactions. HLPI-Ensemble adopts the ensemble strategy based on three mainstream machine learning algorithms of Support Vector Machines (SVM), Random Forests (RF) and Extreme Gradient Boosting (XGB) to generate HLPI-SVM Ensemble, HLPI-RF Ensemble and HLPI-XGB Ensemble, respectively. The results of 10-fold cross-validation show that HLPI-SVM Ensemble, HLPI-RF Ensemble and HLPI-XGB Ensemble achieved AUCs of 0.95, 0.96 and 0.96, respectively, in the test dataset. Furthermore, we compared the performance of the HLPI-Ensemble models with the previous models through external validation dataset. The results show that the false positives (FPs) of HLPI-Ensemble models are much lower than that of the previous models, and other evaluation indicators of HLPI-Ensemble models are also higher than those of the previous models. It is further showed that HLPI-Ensemble models are superior in predicting human lncRNA-protein interaction compared with previous models. The HLPI-Ensemble is publicly available at: http://ccsipb.lnu.edu.cn/hlpiensemble/ . PMID- 29583070 TI - A developmental cascade perspective of paediatric obesity: a conceptual model and scoping review. AB - Considering the immense challenge of preventing obesity, the time has come to reconceptualise the way we study the obesity development in childhood. The developmental cascade model offers a longitudinal framework to elucidate the way cumulative consequences and spreading effects of risk and protective factors, across and within biopsychosocial spheres and phases of development, can propel individuals towards obesity. In this article, we use a theory-driven model building approach and a scoping review that included 310 published studies to propose a developmental cascade model of paediatric obesity. The proposed model provides a basis for testing hypothesised cascades with multiple intervening variables and complex longitudinal processes. Moreover, the model informs future research by resolving seemingly contradictory findings on pathways to obesity previously thought to be distinct (low self-esteem, consuming sugary foods, and poor sleep cause obesity) that are actually processes working together over time (low self-esteem causes consumption of sugary foods which disrupts sleep quality and contributes to obesity). The findings of such inquiries can aid in identifying the timing and specific targets of preventive interventions across and within developmental phases. The implications of such a cascade model of paediatric obesity for health psychology and developmental and prevention sciences are discussed. PMID- 29583071 TI - ? PMID- 29583072 TI - ?

AB - PURPOSE: Adolescence is a transition period involving complex development processes. A life-threatening disease like cancer jeopardizes this development and often exposes adolescents to hospital environments that are unadjusted to them. Despite growing research on how the physical environment affects the well being of the (child as) patient, adolescents are often overlooked. We investigated how adolescents experience a hospital stay and how the physical environment influences that experience. METHODS: We interviewed ten adolescents who are or have been affected by cancer between the age of 14 and 25, and discussed preliminary findings with professional experts. RESULTS: In young people's experience of a hospital environment three interrelated themes stand out: support, distraction, control, and autonomy. Adolescent patients primarily look for connections with life outside the hospital. The hospital confronts them with different obstacles, most of which appear to relate to difficulties concerning the loss of these connections. These obstacles include a lack of freedom, control, and autonomy; limited social interaction with friends; inability to participate in daily activities; boredom; and a lack of privacy. CONCLUSION: As a group, adolescent patients clearly have specific characteristics and needs. This specificity, which is largely hidden in the development and transition they are undergoing, explains the need for a hospital environment dedicated to them-be it a separate adolescent ward, or the grouping of adolescents on children's and/or adult wards. Rather than focusing on a superficial list of wishes and needs, the design of this environment should consider the specific reasons driving adolescents' wishes and needs.

PMID- 29583078 TI - Effectiveness and Safety of Treatment with Direct Oral Anticoagulant Rivaroxaban in Patients with Slow-Flow Vascular Malformations: A Case Series. AB - BACKGROUND: Slow-flow vascular malformations (VM) can be associated with localized intravascular coagulopathy (LIC) that is characterized by elevated D Dimer levels and low fibrinogen and platelets. This can lead to bleeding and clotting tendencies, which can give rise to functional limitations such as pain and swelling and even progress to disseminated intravascular coagulopathy. METHODS AND RESULTS: We conducted a chart review of four patients with evidence of LIC who were started on rivaroxaban. We found an improvement of D-Dimer and/or fibrinogen levels in all four patients. They also had an improvement of pain and functionality. CONCLUSIONS: We report on four patients in whom anticoagulation with a direct oral anticoagulant, rivaroxaban, was effective in controlling signs and symptoms of consumptive coagulopathy with no evidence of bleeding from the use of rivaroxaban. PMID- 29583079 TI - Stigma-related access barriers and violence against trans women in the Colombian healthcare system. AB - Drawing from qualitative research conducted in a participatory action research framework with 28 transgender women in Colombia, this paper presents the stigma related barriers to healthcare experienced by trans women and their experiences of multi-level violence within the healthcare system. The authors also discuss how advocacy work was conducted as part of the research process and how trans community leaders were involved throughout the project in order to promote policy relevance and community-based implementation of findings. The paper concludes with a discussion of how the experiences of violence and stigmatisation within the health care system is linked to broader processes of structural stigma reproduced within Colombian society. PMID- 29583080 TI - Optimal Laser Phototherapy Parameters for Pain Relief. AB - BACKGROUND AND OBJECTIVE: Studies on laser phototherapy for pain relief have used parameters that vary widely and have reported varying outcomes. The purpose of this study was to determine the optimal parameter ranges of laser phototherapy for pain relief by analyzing data aggregated from existing primary literature. MATERIALS AND METHODS: Original studies were gathered from available sources and were screened to meet the pre-established inclusion criteria. The included articles were then subjected to meta-analysis using Cohen's d statistic for determining treatment effect size. From these studies, ranges of the reported parameters that always resulted into large effect sizes were determined. These optimal ranges were evaluated for their accuracy using leave-one-article-out cross-validation procedure. RESULTS: A total of 96 articles met the inclusion criteria for meta-analysis and yielded 232 effect sizes. The average effect size was highly significant: d = +1.36 [confidence interval (95% CI) = 1.04-1.68]. Among all the parameters, total energy was found to have the greatest effect on pain relief and had the most prominent optimal ranges of 120-162 and 15.36-20.16 J, which always resulted in large effect sizes. The cross-validation accuracy of the optimal ranges for total energy was 68.57% (95% CI = 53.19-83.97). Fewer and less-prominent optimal ranges were obtained for the energy density and duration parameters. None of the remaining parameters was found to be independently related to pain relief outcomes. CONCLUSIONS: The findings of meta-analysis indicate that laser phototherapy is highly effective for pain relief. Based on the analysis of parameters, total energy can be optimized to yield the largest effect on pain relief. PMID- 29583082 TI - Test Selection for Women with Suspected Stable Ischemic Heart Disease. AB - Ischemic heart disease (IHD) is the leading cause of death and disability among women in the United States. Identifying IHD in women presenting with stable symptoms and stratifying their risk for an IHD event can be challenging for providers, with several different tests available. This article is meant to serve as a practical guide for clinicians treating women with potentially ischemic symptoms. Evidence and American Heart Association (AHA) recommendations regarding test selection are reviewed, with a focus on the information to be gained from each test. We outline suggested courses of action to be taken in the case of a positive or negative test. Regardless of the initial test result, clinicians should view a woman's symptom presentation as an opportunity to review and modify her risk of cardiovascular events. PMID- 29583081 TI - Lipid Effects of Icosapent Ethyl in Women with Diabetes Mellitus and Persistent High Triglycerides on Statin Treatment: ANCHOR Trial Subanalysis. AB - BACKGROUND: High triglycerides (TG) and diabetes mellitus type 2 (DM2) are stronger predictors of cardiovascular disease (CVD) in women than in men, but few randomized, controlled clinical trials have investigated lipid-lowering interventions in women and none have reported results specifically in women with high TG and DM2. Icosapent ethyl (Vascepa) is pure prescription eicosapentaenoic acid (EPA) ethyl ester approved at 4 g/day as an adjunct to diet to reduce TG >=500 mg/dL. METHODS: The 12-week ANCHOR trial randomized 702 statin-treated patients (73% with DM; 39% women) at increased CVD risk with TG 200-499 mg/dL despite controlled low-density lipoprotein cholesterol (LDL-C; 40-99 mg/dL) to receive icosapent ethyl 2 g/day, 4 g/day, or placebo. This post hoc analysis included 146 women with DM2 (97% white, mean age 62 years) randomized to icosapent ethyl 4 g/day (n = 74) or placebo (n = 72). RESULTS: Icosapent ethyl significantly reduced TG (-21.5%; p < 0.0001) without increasing LDL-C and lowered other potentially atherogenic lipid/lipoprotein, apolipoprotein, and inflammatory parameters versus placebo. Icosapent ethyl increased EPA levels in plasma (+639%; p < 0.0001; n = 49) and red blood cells (+599%; p < 0.0001; n = 47) versus placebo. Safety and tolerability of icosapent ethyl were generally similar to placebo. CONCLUSION: In women with DM2 at high CVD risk with persistently high TG on statins, icosapent ethyl 4 g/day reduced potentially atherogenic parameters with safety and tolerability comparable to placebo. Potential CVD benefits of icosapent ethyl are being tested in ~8000 men and women at high CVD risk with high TG on statins in the ongoing Reduction of Cardiovascular Events with Icosapent Ethyl - Intervention Trial (REDUCE-IT) cardiovascular (CV) outcome trial. PMID- 29583083 TI - Postmenopausal Osteoporosis: A Clinical Review. AB - In postmenopausal women, osteoporotic fractures are more common than stroke, myocardial infarction, and breast cancer combined, and fractures can be costly and result in disability or death. Because there are no signs or symptoms of osteoporosis other than fracture, risk assessment is necessary to identify those at higher risk for clinical events. For women, a clinical fracture risk assessment (FRAX) is appropriate at menopause. Bone mineral density (BMD) measurement is recommended for women at age 65, and earlier for those who have risk factors. Adequate calcium, vitamin D, and weight-bearing exercise are important for bone health at all ages, and those at high risk for fracture based on BMD or FRAX should be offered medical therapy to reduce fracture risk after an appropriate medical evaluation. Bisphosphonates can accumulate in bone, so after a period of treatment, lower risk patients may be offered a period off drug therapy. However, the effects of denosumab are not sustained when treatment is discontinued, so there is no "drug holiday" with denosumab. Anabolic therapy can be offered to those with higher risk for fracture. Although rare safety concerns regarding atypical femoral fracture and osteonecrosis of the jaw have received prominent attention, for patients who are appropriately treated according to National Osteoporosis Foundation guidelines, the benefit of hip fracture risk reduction far outweighs the risk of these uncommon side effects. Accurate information for patients and shared decision-making are important for acceptance and persistent with appropriate treatment. PMID- 29583084 TI - The Effect of Cervical Smears Performed by General Practitioners on the Cervical Cancer Screening Rate of their Female Patients: A Claim Database Analysis and Cross-Sectional Survey. AB - PURPOSE: Cervical cancer screening reduces the incidence and specific mortality rate of cervical neoplasms. In most cases screening by means of Pap smears is performed in France by gynecologists. The primary objective of this study was to confirm whether the participation rate is increased when general practitioners (GPs) carry out the smears themselves. The secondary objective was to evaluate other independent characteristics of GPs predicting participation rates in women. METHODS: The population of 347 GPs, including their relevant characteristics and their 90,094 female patients eligible for screening over 2 years (2013-2014), was derived from the SIAM claim database of the Flanders Healthcare Insurance Fund (CPAM). A telephone survey among all GPs was carried out to know whether they were performing smears in their surgeries. RESULTS: A total of 343 GPs were included for analysis (98.8% participation rate). The mean cervical cancer screening participation rate over 2 years among all the women in the recommended age group (25-65 years) was 43.3% (+/-6.9). Bivariate analysis showed that participation rate was higher when the GP performed smears (adjusted difference of mean: 2.06 [95% CI: 0.67-3.45], p = 0.037) and whether the GP was female (2.08 [0.42-3.74], p = 0.0144). After multivariate analysis the only significant characteristic of the GP was the performance of smears (1.71 [0.27-3.16], p = 0.0204). CONCLUSIONS: Cervical smears performed by GPs led to increased screening participation rates within the recommended age group of women. However, the size of this increase is insufficient to reach the expected participation rates. PMID- 29583086 TI - Dual infection of the central nervous system caused by Cryptococcus and Toxoplasma in a patient with AIDS: a case report and literature review. AB - Dual infection of the central nervous system secondary to Cryptococcus and Toxoplasma is very uncommon, even in the setting of acquired immunodeficiency syndrome (AIDS). We report the case of a 52-year-old patient who was admitted with multiple cranial nerve deficits. Magnetic resonance imaging showed supratentorial and infratentorial enhancing lesions. He was newly diagnosed with HIV infection with a CD4 count of 59 cells/uL and HIV viral load of 299,619 copies/mL. Diagnosis of Cryptococcus meningitis was made by Cryptococcal antigen in cerebrospinal fluid (CSF). The high clinical suspicion for Toxoplasmosis prompted an early empiric treatment for this condition. The diagnosis of Toxoplasmosis was later confirmed by PCR in CSF. Despite an adequate treatment for these two pathologies, his condition deteriorated and eventually expired. We reviewed the English language literature for cases of Cryptococcus and Toxoplasma co-infection of the central nervous system in patients with AIDS. To our knowledge, our patient is the third case of simultaneous infection described in the literature. Clinicians must be aware that focal brain lesions in patients with cryptococcal meningitis should prompt a full evaluation to search for concomitant pathologies of which Toxoplasmosis is the most important. Our case illustrates the utility of PCR in CSF for an early diagnosis of toxoplasmosis, reserving brain biopsy for cases of anti-toxoplasma therapy failure. PMID- 29583087 TI - Regulation of Constitutive Tip110 Expression in Human Cord Blood CD34+ Cells Through Selective Usage of the Proximal and Distal Polyadenylation Sites Within the 3'Untranslated Region. AB - Tip110 plays important roles for stem cell pluripotency and hematopoiesis. However, little is known about the regulatory mechanisms of Tip110 expression in this process. In this study, we first showed that constitutive Tip110 expression was cell proliferation and differentiation dependent and self-regulated in both human cord blood CD34+ cells. Using a series of molecular techniques, we found that ectopic Tip110 expression led to increased constitutive Tip110 expression through its 3'-untranslated region (3'UTR), specifically through preferential usage of proximal polyadenylation sites within its 3'UTR in cells, including human cord blood CD34+ cells, which indeed led to an increased number of CD34+ cells during differentiation of those cells. Lastly, we showed that Tip110 protein interacted with cleavage stimulation factor 64 (CstF64) protein and that more CstF64 was recruited to the promixal polyadenylation site than the distal polyadenylation site within its 3'UTR. These finding together demonstrates that constitutive Tip110 expression is regulated, at least in part, through its interaction with CstF64, recruitment of CstF64 to, and selective usage of those two polyadenylation sites within its 3'UTR.

AB - Specification of endothelial cells (ECs) into arterial, venous, and lymphatic cells is a crucial process of vascular development, and expanding our knowledge about EC specification from human pluripotent stem cells (hPSCs) will aid the design of optimal strategies for producing desired types of ECs for therapies. In our prior studies, we revealed that hPSC-derived VE-cadherin(V)+CD31+CD34+ ECs are heterogeneous and include at least three major subsets with distinct hemogenic properties: V+CD43/235a-CD73- hemogenic endothelial progenitors (HEPs), V+CD43loCD235a+73- angiogenic hematopoietic progenitors (AHPs), and V+CD43/235a 73+ non-HEPs. In this study, using angiogenesis assays, we demonstrated that ECs within these subsets have distinct endothelial colony- and tube-forming properties, proliferative and migratory properties, and endothelial nitric oxide synthase and inflammatory cytokine production potentials. Culture of isolated subsets in arterial, venous, and lymphatic conditions revealed that AHPs are skewed toward lymphatic, HEPs toward arterial, and non-HEPs toward venous differentiation in vitro. These findings suggest that selection and enhancement of production of a particular EC subset may aid in generating desirable EC populations with arterial, venous, or lymphatic properties from hPSCs.

AB - A pair of lightweight electrically heated gloves (EHG) with smart temperature control function was developed. To evaluate the thermoregulation properties of the EHG, human trials were conducted in a climate chamber (2.5 degrees C, 60% RH). The changes in skin temperature at all fingers and the opisthenar, and the subjective thermal sensation were recorded over 60 min. The effects of two air velocities (i.e., 0.17 and 0.50 m/s) on the cold protective performance of the EHG in scenarios of heating and control were also investigated. For heating scenarios, skin temperature and thermal sensation at all fingers and the opisthenar were found significantly higher than those in control conditions. Moreover, the air velocity at 0.50 m/s greatly reduced the cold protective performance of the gloves. The research findings can be applied to improve thermal comfort and extend working times for persons in cold environments. PMID- 29583089 TI - ? PMID- 29583090 TI - ? PMID- 29583091 TI - ?

AB - Objective This prospective study evaluated the time to response and outcomes of navigated repetitive transcranial magnetic stimulation (TMS) at a frequency of 10 Hz in patients with chronic neuropathic pain. Methods This prospective study included patients with unilateral chronic neuropathic pain. All patients received motor cortex stimulation at 10 Hz over nine consecutive days using repetitive TMS. Outcome was evaluated over a six-week follow-up period using the visual analogue scale, the German Pain Questionnaire and time to pain reduction. Results Fifty patients (23 female, 27 male) were recruited. Two patients were excluded from analysis owing to premature discontinuation of treatment and follow-up. 31/48 patients in the cohort suffered from atypical facial pain. The pain duration ranged approximately from six months to 27 years. After six weeks, 28/46 patients reported a significant level of pain relief (P < 0.001). Conclusion Navigated repetitive TMS for chronic pain is a non-invasive modality with demonstrable clinical benefit. In particular, patients with atypical facial pain with a clear clinicoanatomical correlate responded well to high-frequency stimulation. Patients with a mean pain history of less than five years benefited significantly from this treatment, so early treatment with repetitive TMS should be encouraged. PMID- 29583100 TI - ? PMID- 29583101 TI - Safety of percutaneous axillary artery access with a suture-mediated closing device for parallel endograft aortic procedures - a retrospective pilot study. AB - BACKGROUND: The aim of this study was to evaluate the technical success of percutaneous ultrasound-guided access to the infraclavicular axillary artery with a suture-mediated closing device for patients requiring large-sized upper extremity access. PATIENTS AND METHODS: In 18 consecutive patients (17 male, one female, mean age 73.5 +/- 9.6 years, range 52-88 years), artery accesses with the preclosing modification for chimney endografts was gained with 20 ultrasound guided infraclavicular axillary. Retrospectively, the following endpoints were analysed: technical success of percutaneous ultrasound-guided puncture of the infraclavicular axillary artery as well as introduction and deployment, primary successful haemostasis by preclosing, bailout procedures, overall complication rate including local vascular, cerebrovascular, and peripheral neurological complications. RESULTS: Ultrasound-guided puncture and preclosing procedure was successful in all patients. Mean sheath size was 9.4 +/- 1.6 French. Ultrasound guided puncture as well as introduction and deployment were successful in all patients (100 %). Primary successful haemostasis by preclosing was 70 % (14/20). Postclosing with one or two devices enabled successful haemostasis in another 15 %. Bailout stent graft implantation was necessary in three accesses (15 %), either by transfemoral (n = 2) or transbrachial (n = 1) route. Overall complication rate was 16.5 %, all of them were minor haematomas. CONCLUSIONS: Percutaneous ultrasound-guided infraclavicular axillary artery access with preclosing modification seems feasible and safe. The access related complication rate is low and complications can potentially be managed by endovascular means. PMID- 29583103 TI - The rural interdisciplinary team training program: a workforce development workshop to increase geriatrics knowledge and skills for rural providers. AB - The Rural Interdisciplinary Team Training Program (RITT) is a team-based educational component of the Veterans Health Administration (VHA) Office of Rural Health Geriatric Scholars Program. It is a workforce development program to enhance the geriatrics knowledge and skills of VA primary care clinicians and staff caring for older veterans in rural communities. The RITT workshop, accredited for 6.5 hours, is interactive and multi-modal with didactic mini lectures, interactive case discussions and role play demonstrations of assessments. Clinic teams also develop and implement a small quality improvement project based on common challenges faced by older persons. This report is an evaluation of the effect of the RITT Program on geriatrics knowledge and team development as well as success in developing and implementing the quality improvement projects in 80 VHA rural outpatient clinics in 38 states. PMID- 29583104 TI - Perspectives on family caregiving of people aging with intellectual disability affected by dementia: Commentary from the International Summit on Intellectual Disability and Dementia. AB - This article, an output of the 2016 International Summit on Intellectual Disability and Dementia, examines familial caregiving situations within the context of a support-staging model for adults with intellectual disability (ID) affected by dementia. Seven narratives offer context to this support-staging model to interpret situations experienced by caregivers. The multidimensional model has two fundamental aspects: identifying the role and nature of caregiving as either primary (direct) or secondary (supportive); and defining how caregiving is influenced by stage of dementia. We propose staging can affect caregiving via different expressions: (1) the "diagnostic phase," (2) the "explorative phase," (3) the "adaptive phase," and (4) the "closure phase." The international narratives illustrate direct and indirect caregiving with commonality being extent of caregiver involvement and attention to the needs of an adult with ID. We conclude that the model is the first to empirically formalize the variability of caregiving within families of people with ID that is distinct from other caregiving groups, and that many of these caregivers have idiosyncratic needs. A support-staging model that recognizes the changing roles and demands of carers of people with ID and dementia can be useful in constructing research, defining family-based support services, and setting public policy.

AB - Older adults account for 17% of new HIV diagnoses in the US and are more likely to be diagnosed with HIV later in the course of the disease compared to younger people. We calculated the prevalence and associated factors of having ever been tested for HIV among sexually active older adults. We analyzed data from the 2008 2016 General Social Survey Limited to respondents >=65 years of age who reported more than one sex partner(s) in past 12 months (n = 757). HIV testing prevalence, prevalence ratios, and 95% confidence intervals were calculated by demographic variables and HIV-related risk behaviors. An estimated 16.3% of sexually active older adults have tested for HIV, and 15.9% were at increased risk for HIV infection (reported injection drug and/or crack-cocaine use, exchanging money for sex, more than three sex partners in the past year, or men who reported having sex with another man). In the adjusted model, adults aged 65-70, not married, self-identified as gay/bisexual, and at increased risk for HIV infection were more likely to have tested for HIV. An estimated 83.7% of sexually active older adults never tested for HIV. Strategies are needed to increase HIV awareness and testing among potentially high-risk older adults.

AB - Romantic relationships are known to be very influential, but less is known about how these relationships, and particularly the breakup of these relationships, may affect individuals' relational schemas, or their expectations for relationships. Undergraduate students reported on how their views of themselves, romantic partners, and relationships changed after breaking up with a past partner. Results suggest that relational schemas change following relationship dissolution and that there are both positive and negative aspects to this change. There was also some evidence that aspects of the past relationship predicted change and the valence of change, and that change and the valence of change were related to aspects of current relationship quality. These results are an important first step in understanding how past romantic relationships influence people's expectations about relationships and, by extension, their health and wellbeing. PMID- 29583107 TI - Morphine reduces mouse microglial engulfment induced by lipopolysaccharide and interferon-gamma via delta opioid receptor and p38 mitogen-activated protein kinase. AB - Objective To investigate the effects of morphine on microglial phagocytosis during neuroinflammation. Methods C8-B4 mouse microglial cells were exposed to various concentrations of morphine after the stimulation with lipopolysaccharide and interferon-gamma and then fluorescent immunostaining was performed to assess the percentage of microglia that engulfed fluorescent microspheres in total microglia. Naloxone, beta funaltrexamine, or naltrindole was used with 1 MUM morphine to assess the involvement of specific opioid receptor. P38 and phosphorylated p38 were determined by Western blotting. A p38 mitogen-activated protein kinase (MAPK) activator (anisomycin 0.1 MUM) or inhibitor (SB 203580, 20 MUM) was used to determine the involvement of p38 MAPK pathway. Results Morphine decreased lipopolysaccharide and interferon-gamma-induced microglial engulfment except the highest concentration (10 MUM) and both naloxone and naltrindole (a selective delta opioid receptor antagonist) attenuated morphine effect (p < 0.001). The phosphorylated p38 was up-regulated in lipopolysaccharide and interferon-gamma group compared with control group (p < 0.001). This up regulation was decreased by 1 MUM morphine (p < 0.001). However, naltrindole abolished this morphine effect (p = 0.015). SB203580 blocked the increased microglial engulfment induced by lipopolysaccharide and interferon-gamma (p < 0.001); whereas, anisomycin enhanced the morphine-induced decrease of engulfment (p < 0.001). Conclusion Morphine reduced mouse microglial engulfment induced by lipopolysaccharide and interferon-gamma. This morphine effect seems to be mediated by delta opioid receptor and via p38 MAPK inhibition. PMID- 29583108 TI - Bronchoscopic Improvement of Tracheobronchitis Due to Methicillin-Resistant Staphylococcus aureus After Aerosolized Vancomycin: A Case Series. AB - BACKGROUND: Ventilator-associated tracheobronchitis (VAT) is an important risk factor for ventilator-associated pneumonia (VAP). The efficacy of aerosolized vancomycin (AV) in treating VAT has not been clearly demonstrated. METHODS: Four mechanically ventilated patients with methicillin-resistant Staphylococcus aureus (MRSA) pneumonia were treated with an additional AV. AV (250 mg twice per day) was administered through a vibrating mesh device for 5 days. All patients were receiving intravenous vancomycin and had severe tracheobronchitis, based on bronchoscopic findings before or soon after additional AV treatment. RESULTS: After several days of AV treatment, follow-up bronchoscopies showed dramatic improvement of tracheobronchitis. All patients achieved microbiological eradication of MRSA. Finally, two of four patients survived through to hospital discharge. CONCLUSION: This case series study suggests a potential role of AV in the treatment of MRSA tracheobronchitis, which were accompanied by VAP. Clinical trial addressing the efficacy of AV in MRSA VAT and/or VAP should be needed.

PMID- 29583110 TI - Vitamin A Supplementation by Endotracheal Application of a Nano-encapsulated Preparation Is Feasible in Ventilated Preterm Lambs. AB - BACKGROUND: Vitamin A (VA) is crucial for lung growth and development. In premature infants, inadequate VA levels are associated with an increased risk of bronchopulmonary dysplasia (BPD). Intramuscular VA supplementation has been shown to decrease the incidence of BPD, but is not widely used in the clinical setting due to concerns about feasibility and pain. We studied VA kinetics, distribution, and the induction of early genetic expression of retinoid homeostatic genes in the lung after endotracheal and intravenous application in a preterm lamb model. METHODS: Lambs were delivered prematurely after 85% of gestation, intubated, and ventilated for 3 hours. The animals were randomized to receive no VA ("control"), a bolus of VA intravenously ("i.v."), or VA endotracheally directly after administration of surfactant ("e.t."). RESULTS: Animals treated with VA endotracheally directly after administration of surfactant showed significant increases of VA in serum and lung compared to controls. Animals treated with a bolus of VA intravenously showed significant increases of VA in serum, lung, and liver; however, peak serum concentrations and mRNA levels of homeostatic genes raised concerns about toxicity in this group. CONCLUSIONS: Endotracheal VA supplementation in preterm lambs is feasible and might offer advantages in comparison to i.v. Further studies are warranted to explore biological effects in the context of BPD.

PMID- 29583112 TI - Ellagibacter isourolithinifaciens gen. nov., sp. nov., a new member of the family Eggerthellaceae, isolated from human gut. AB - Urolithins are gut microbial metabolites that exert health benefits in vivo and are generated from ellagic acid (EA) and ellagitannin-containing foods such as strawberries, pomegranates and walnuts. Gordonibacter species produce some intermediary urolithins but the micro-organisms responsible for the transformation of EA into the final and more bioactive urolithins, such as urolithin A and isourolithin A, are unknown. We report here a new bacterium, capable of metabolizing EA into isourolithin A, isolated from healthy human faeces and characterized by determining phenotypic, biochemical and molecular methods. Strain CEBAS 4A belongs to the Eggerthellaceae family and differed from other genera of this family, both phylogenetically and phenotypically. Based on 16S rRNA gene sequence similarity, the strain was related to Enterorhabdus musicola DSM 19490T (92.9 % similarity), Enterorhabdus caecimuris DSM 21839T (92.7 % similarity), Adlercreutzia equolifaciens DSM 19450T (92.5 % similarity), Asaccharobacter celatus DSM 18785T (92.5 % similarity) and Parvibacter caecicola DSM 22242T (91.2 % similarity). This strain was strictly anaerobic and Gram-stain positive. The whole-cell fatty acids were saturated (98.3 %), a very high percentage that differs from the nearest genera ranging from 62 to 73 %. The major respiratory lipoquinone was menaquinone-7 and the diamino acid in the peptidoglycan was meso-diaminopimelic acid. Diphosphatidylglycerol and phosphatidylglycerol comprised the main polar lipid profile in addition to several phosphoglycolipids (PGL1-2), phospholipids (PL1-4), glycolipids (GL1-6) and lipids. Based on these data, a new genus, Ellagibacter gen. nov. is proposed with one species, Ellagibacter isourolithinifaciens sp. nov. The type strain of Ellagibacter isourolithinifaciens is CEBAS 4AT (=DSM 104140T=CCUG 70284T). PMID- 29583113 TI - Whole-genome sequencing revealed concurrent outbreaks of shigellosis in the English Orthodox Jewish Community caused by multiple importations of Shigella sonnei from Israel. AB - In December 2013, Public Health England (PHE) observed an increase in the number of cases of Shigella sonnei linked to the Orthodox Jewish Community (OJC). Ultimately, 52 cases of S. sonnei phage type (PT) P and PT7 were notified between November 2013 and July 2014. Whole-genome sequencing (WGS) was performed on a HiSeq 2500 platform (Illumina) on isolates of S. sonnei submitted to PHE during the investigation. Quality trimmed sequence reads were mapped to a reference genome using BWA-MEM, and single-nucleotide polymorphisms (SNPs) were identified using GATK2. Analysis of the core genome SNP positions (>90 % consensus, minimum depth 10*, MQ>=30) revealed that isolates linked to the outbreak could be categorized as members of distinct monophyletic clusters (MPCs) representing concurrent regional outbreaks occurring in the OJCs across the United Kingdom. A dated phylogeny predicted the date of the most recent common ancestor of the MPCs to be approximately 3.1 years previously [95 % highest posterior density (HPD), 2.4-3.4]. Isolates of S. sonnei from cases from the OJCs in Israel included in the phylogeny, branched from nodes basal to the UK OJC outbreak clusters, indicating they were ancestral to the UK OJC isolates, and that the UK isolates represented multiple importations of S. sonnei into the UK population from Israel. The level of discrimination exhibited by WGS facilitated the identification of clusters of isolates within the closely related bacterial populations circulating in the OJC that may be linked to a unique point sources or transmission routes, thus enabling a more appropriate public health response and targeted interventions. PMID- 29583114 TI - GlnR and PhoP regulate beta-glucosidases involved in cellulose digestion in response to nitrogen and phosphate availability. AB - The limited catalytic efficiency of cellulose-degrading enzymes restricts cellulose digestion. We investigated the transcriptional regulation of genes encoding key cellulose degrading enzymes, namely beta-glucosidases, in the industrial actinobacterium Saccharopolyspora erythraea. We observed that the expression of most beta-glucosidase-encoding genes was controlled by the availability of nitrogen and phosphate via their respective global regulators, namely GlnR and PhoP. Electrophoretic mobility shift assay demonstrated that GlnR and PhoP bound directly to the promoters of beta-glucosidase-encoding genes. Deletion of glnR resulted in lower transcript levels and activity of beta glucosidases, leading to decreased bacterial growth on cellulose. Overexpression of glnR and phoP or nitrogen/phosphate starvation increased the transcript levels and total activity of beta-glucosidases. Moreover, GlnR/PhoP-mediated cellobiose utilization was also observed in Streptomyces coelicolor A3(2). These findings provide insights into the regulatory roles played by GlnR and PhoP in coordinating nitrogen/phosphate metabolism and carbohydrate utilization, and indicate potential strategies for cellulose fermentation in the production of bio based chemicals by actinobacteria. PMID- 29583115 TI - DNA indicative of human bocaviruses detected in non-human primates in the Democratic Republic of the Congo. AB - Bocaparvoviruses are members of the family Parvovirinae and human bocaviruses have been found to be associated with respiratory and gastrointestinal disease. There are four known human bocaviruses, as well as several distinct ones in great apes. The goal of the presented study was to detect other non-human primate (NHP) bocaviruses in NHP species in the Democratic Republic of the Congo using conventional broad-range PCR. We found bocavirus DNA in blood and tissues samples in 6 out of 620 NHPs, and all isolates showed very high identity (>97 %) with human bocaviruses 2 or 3. These findings suggest cross-species transmission of bocaviruses between humans and NHPs. PMID- 29583116 TI - Lelliottia jeotgali sp. nov., isolated from a traditional Korean fermented clam. AB - Strain PFL01T was isolated from traditional Korean fermented clam, jogae-jeotgal, and characterized. The strain was a facultative anaerobic, Gram-stain-negative bacterium that was rod-shaped, motile and beige-pigmented. The phylogenetic sequence analysis based on the 16S rRNA gene from PFL01T revealed that it was closely related to Lelliottia nimipressuralis LMG 10245T and Lelliottia amnigena LMG 2784T with 99.3 and 99.3 % sequence identities, respectively. Multilocus sequence type analysis of concatenated partial aptD, gyrB, infB and rpoB gene sequences showed a clear distinction of strain PFL01T from its closest related type strains. The discrimination was also supported by unique repetitive extragenic palindromic PCR (Rep-PCR, ERIC-PCR) fingerprint patterns. In addition, results from average nucleotide identity analyses with other species were less than 85 %. vitek and API analyses revealed distinct characteristics from other species of Lelliottia. The cellular fatty acid profile of the strain consisted of C16 : 0, cyclo-C17 : 0, C16 : 1omega7c/C16 : 1omega6c and C18 : 1omega7c/C18 : 1omega6c as major components. The whole genome of PFL01T was 4.6 Mb with a G+C content of 55.3 mol%. Based on these results, strain PFL01T was classified as a novel species of the genus Lelliottia, for which the name Lelliottia jeotgali sp. nov. is proposed. The type strain in PFL01T (=KCCM 43247T=JCM 31901T). PMID- 29583118 TI - The current state of resident trauma training: Are we losing a generation? AB - SUMMARY: General surgeons provide life-saving trauma care to a large portion of Canadians. Although trauma care has evolved significantly over the last few decades and now requires fewer operations, when a life-saving operation is required the expectation of competence to perform this operation has not been reduced. A recent study from the United States found decreased resident case-log volumes of trauma operations. Such findings raise the alarm of declining exposure of residents to trauma operations and beg the question of whether graduating residents are competent to care for trauma patients. Examination of the Canadian setting reveals a dearth of published information about the actual exposure of Canadian general surgery residents to trauma care. With the forthcoming evolution of general surgery education into competency-based medical education, we sound a call to action to ensure that all graduating general surgeons are able to provide the care that both the Royal College of Physicians and Surgeons of Canada and the Canadian public demand. PMID- 29583117 TI - The lytic Myoviridae of Enterobacteriaceae form tight recombining assemblages separated by discontinuities in genome average nucleotide identity and lateral gene flow. AB - In Bacteria, a working consensus of species circumscription may have been reached and one of the most prominent criteria is high average nucleotide identity (ANI). ANI in effect groups strains that may recombine more or less frequently, depending on their biology, as opposed to rare interspecies gene transfer. For bacteriophages, which show various lifestyles, the nature of the fundamental natural unit, if it exists in a biological sense, is not well understood and defined. The approaches based on dot-plots are useful to group similar bacteriophages, yet are not quantitative and use arbitrarily set cut-offs. Here, we focus on lytic Myoviridae and test the ANI metric for group delineation. We show that ANI-based groups are in agreement with the International Committee on Taxonomy of Viruses (ICTV) classification and already established dot-plot groups, which are occasionally further refined owing to higher resolution of ANI analysis. Furthermore, these groups are separated among themselves by clear ANI discontinuities. Their members readily exchange core genes with each other while they do not with bacteriophages of other ANI groups, not even with the most similar. Thus, ANI-delineated groups may represent the natural units in lytic Myoviridae evolution with features that resemble those encountered in bacterial species. PMID- 29583119 TI - Management of intra-abdominal vascular injury in trauma laparotomy: a South African experience. AB - BACKGROUND: Intra-abdominal vascular injury (IAVI) is uncommon but continues to be associated with high mortality rates despite technological advances in the past decades. In light of these ongoing developments, we reviewed our contemporary experience with IAVI in an attempt to clarify and refine our management strategies and the outcome of these patients. METHODS: We retrospectively reviewed the charts of all patients admitted between January 2011 and December 2014 at a major trauma centre in South Africa who were found to have an IAVI during laparotomy for trauma. We collected demographic and clinical data including mechanism of injury, location and severity of the injury, concurrent injuries, physiologic parameters and clinical outcome. RESULTS: We identified 110 patients with IAVIs, of whom 98 had sustained penetrating injuries (55 gunshot wounds and 43 stab wounds). There were 84 arterial injuries (including 21 renal and 17 mesenteric) and 74 venous injuries (including 21 renal and 17 inferior vena caval). Combined venous and arterial injuries were found in almost one-third of patients (34 [30.9%]). Fifty-seven patients (51.8%) required intensive care admission. The overall mortality rate was 28.2% (31 patients); the rate was 62% for aortic injuries and 47% for inferior vena cava injuries. Liver injury, large bowel injury, splenic injury and elevated lactate level were all associated with a statistically significantly higher mortality rate. CONCLUSION: The mortality rate for IAVI remains high despite decades of operative experience in high-volume centres. Open operative techniques alone are unlikely to achieve further reduction in mortality rates. Integration of endovascular techniques may provide an alternative strategy to improve outcomes.

PMID- 29583121 TI - A quinoline compound inhibits the replication of dengue virus serotypes 1-4 in Vero cells. AB - BACKGROUND: The global occurrence of dengue, a mosquito-borne viral disease caused by four distinct dengue viruses (DENV-1, -2, -3 and -4), is reported to have increased approximately 30-fold in the last 50 years, causing approximately 400 million infections a year. A limited use, sub-optimal live attenuated dengue vaccine has become available recently. It is becoming apparent that antibodies to DENVs can promote infection by Zika virus (ZIKV), a related mosquito-borne flavivirus. A drug to treat these flaviviral infections continues to be an unmet public health need. METHODS: We screened an 'in-house' library of approximately 2,000 small molecules for inhibitors of cloned DENV-2 protease. Putative inhibitor binding to DENV-2 protease was analysed by in silico docking. Anti-DENV activity was analysed by monitoring viral antigen synthesis by ELISA, viral RNA synthesis by reverse-transcription coupled to real-time polymerase chain reaction and infectious virus production by plaque assay, in DENV-infected Vero cells. RESULTS: A quinoline derivative, BT24, was identified for the first time as a potent inhibitor of the cloned DENV-2 protease (half maximal inhibitory concentration [IC50]=0.5 uM). In silico analysis revealed that BT24 binds to an allosteric site in the vicinity of the active site of DENV-2 protease. Cell-based assays demonstrated that BT24 can inhibit all four DENVs in infected Vero cells. CONCLUSIONS: BT24 is a DENV-2 protease inhibitor which manifests the capacity to inhibit the replication of all four DENVs in cultured cells. It may provide a lead for a pan-DENV inhibitory drug. PMID- 29583122 TI - Loss to follow-up and associated factors of patients in the National AIDS Program in Thailand. AB - BACKGROUND: Loss to follow-up (LTFU) is a crucial indicator to evaluate the effectiveness of HIV care and treatment programmes. We assessed the LTFU rate and associated factors of Thai HIV-infected patients who enrolled in the National AIDS Program (NAP) for two periods: prior to (pre-ART) and after starting ART (ART-patients). METHODS: Thai HIV patients aged >=15 years enrolled in NAP from 2008 to 2014. Vital status was ascertained by linkage with the National Death Registry. Competing risk models were used to calculate the adjusted sub distribution hazards (aSHR) for LTFU for pre-ART and ART-patients, with death considered as a competing risk. RESULTS: A total of 157,026 patients registered in care and were included in analyses. The cumulative incidence of LTFU in pre ART patients at 1 year was 10.2%, whereas in ART-patients it was 12.8%. Among pre ART patients, younger age (<30 versus >=45 years, aSHR 1.60, 95% CI 1.49, 1.72), less advanced HIV stage (aSHR 1.29, 95% CI 1.21, 1.37) and higher CD4+ T-cell count (>=350 versus <100, aSHR 6.31, 95% CI 5.74, 6.95) had a higher chance of LTFU. ART-patients with high baseline CD4+ T-cell count (CD4 >=350 versus CD4 <50, aSHR 2.06, 95% CI 1.97, 2.15) and non-advanced HIV stage had increased risk of LTFU. CONCLUSIONS: Our findings provide new evidence of the LTFU rate in Thai HIV-infected patients in NAP. Emphasis needs to be placed on improving follow-up in all patients with higher CD4+ T-cell counts. LTFU will be important to monitor as programmes move to commence ART regardless of CD4+ T-cell count. PMID- 29583123 TI - Effect of atomic disorder on the magnetic phase separation. AB - The effect of disorder on the magnetic phase separation between the antiferromagnetic and incommensurate helical [Formula: see text] and [Formula: see text] phases is investigated. The study is based on the quasi-two-dimensional single-band Hubbard model in the presence of atomic disorder (the [Formula: see text] Anderson-Hubbard model). A model of binary alloy disorder is considered, in which the disorder is determined by the difference in energy between the host and impurity atomic levels at a fixed impurity concentration. The problem is solved within the theory of functional integration in static approximation. Magnetic phase diagrams are obtained as functions of the temperature, the number of electrons and impurity concentration with allowance for phase separation. It is shown that for the model parameters chosen, the disorder caused by impurities whose atomic-level energy is greater than that of the host atomic levels, leads to qualitative changes in the phase diagram of the impurity-free system. In the opposite case, only quantitative changes occur. The peculiarities of the effect of disorder on the phase separation regions of the quasi-two-dimensional Hubbard model are discussed.

AB - We investigate dynamical stability of a single propeller-like shaped molecular cogwheel modelled as the fixed-axis rigid rotator. In the realistic situations, rotation of the finite-size cogwheel is subject to the environmentally-induced Brownian-motion effect that we describe by utilizing the quantum Caldeira-Leggett master equation. Assuming the initially narrow (classical-like) standard deviations for the angle and the angular momentum of the rotator, we investigate the dynamics of the first and second moments depending on the size, i.e. on the number of blades of both the free rotator as well as of the rotator in the external harmonic field. The larger the standard deviations, the less stable (i.e. less predictable) rotation. We detect the absence of the simple and straightforward rules for utilizing the rotator's stability. Instead, a number of the size-related criteria appear whose combinations may provide the optimal rules for the rotator dynamical stability and possibly control. In the realistic situations, the quantum-mechanical corrections, albeit individually small, may effectively prove non-negligible, and also revealing subtlety of the transition from the quantum to the classical dynamics of the rotator. As to the latter, we detect a strong size-dependence of the transition to the classical dynamics beyond the quantum decoherence process.

Heat accumulation increases the baseline temperature and decreases the equilibrium magnetization. Transient ultrafast demagnetization first develops with higher fluence in parallel with strong equilibrium thermal spin fluctuations. The ultrafast demagnetization is then gradually removed as the equilibrium temperature approaches the Curie temperature. The transient magnetization time-dependence is well fit with the spin-flip scattering model.

AB - An a-SiN x -based resistive random access memory (RRAM) device with a forming free characteristic has significant potentials for the industrialization of the next-generation memories. We demonstrate that a forming-free a-SiN x O y RRAM device can be achieved by an oxygen plasma treatment of ultra-thin a-SiN x :H films. Electron spin resonance spectroscopy reveals that Si dangling bonds with a high density (1019 cm-3) are distributed in the initial state, which exist in the forms of Si2N=Si., SiO2=Si., O3=Si., and N3=Si.. X-ray photoelectron spectroscopy and temperature-dependent current analyses reveal that the silicon dangling bonds induced by the oxygen plasma treatment and external electric field contribute to the low resistance state (LRS). For the high resistance state (HRS), the rupture of the silicon dangling bond pathway is attributed to the partial passivation of Si dangling bonds by H+ and O2-. Both LRS and HRS transmissions obey the hopping conduction model. The proposed oxygen plasma treatment, introduced to generate a high density of Si dangling bonds in the SiN x O y :H films, provides a new approach to forming-free RRAM devices.

AB - Axial diffusion in channels and tubes of smoothly-varying geometry can be approximately described as one-dimensional diffusion in the entropy potential with a position-dependent effective diffusion coefficient, by means of the modified Fick-Jacobs equation. In this work, we derive analytical expressions for the position-dependent effective diffusivity for two-dimensional asymmetric varying-width channels, and for three-dimensional curved midline tubes, formed by straight walls. To this end, we use a recently developed theoretical framework using the Frenet-Serret moving frame as the coordinate system (2016 J. Chem. Phys. 145 074105). For narrow tubes and channels, an effective one-dimensional description reducing the diffusion equation to a Fick-Jacobs-like equation in general coordinates is used. From this last equation, one can calculate the effective diffusion coefficient applying Neumann boundary conditions.

AB - In a Bernal graphene bilayer, carbon atoms belong to two inequivalent sublattices A and B, with atoms that are coupled to the other layer by [Formula: see text] bonds belonging to sublattice A and the other atoms belonging to sublattice B. We analyze the density of states and the conductivity of Bernal graphene bilayers when atoms of sublattice A or B only are randomly functionalized. We find that for a selective functionalization on sublattice B only, a mobility gap of the order of 0.5 eV is formed close to the Dirac energy at concentration of adatoms [Formula: see text]. In addition, at some other energies conductivity presents anomalous behaviors. We show that these properties are related to the bipartite structure of the graphene layer. PMID- 29583129 TI - Influence of spin and charge fluctuations on spectra of the two-dimensional Hubbard model. AB - The influence of spin and charge fluctuations on spectra of the two-dimensional fermionic Hubbard model is considered using the strong coupling diagram technique. Infinite sequences of diagrams containing ladder inserts, which describe the interaction of electrons with these fluctuations, are summed, and obtained equations are self-consistently solved for the ranges of Hubbard repulsions [Formula: see text], temperatures [Formula: see text] and electron concentrations [Formula: see text] with t the intersite hopping constant. For all considered U the system exhibits a transition to the long-range antiferromagnetic order at [Formula: see text]. At the same time no indication of charge ordering is observed. Obtained solutions agree satisfactorily with results of other approaches and obey moments sum rules. In the considered region of the U-T plane, the curve separating metallic solutions passes from [Formula: see text] at the highest temperatures to U = 2t at [Formula: see text] for half-filling. If only short-range fluctuations are allowed for the remaining part of this region is occupied by insulating solutions. Taking into account long-range fluctuations leads to strengthening of maxima tails, which transform a part of insulating solutions into bad-metal states. For low T, obtained results allow us to trace the gradual transition from the regime of strong correlations with the pronounced four-band structure and well-defined Mott gap for [Formula: see text] to the Slater regime of weak correlations with the spectral intensity having a dip along the boundary of the magnetic Brillouin zone due to an antiferromagnetic ordering for [Formula: see text]. For [Formula: see text] and [Formula: see text] doping leads to the occurrence of a pseudogap near the Fermi level, which is a consequence of the splitting out of a narrow band from a Hubbard subband. Obtained spectra feature waterfalls and Fermi arcs, which are similar to those observed in hole-doped cuprates. PMID- 29583130 TI - Static dielectric constant of water within a bilayer using recent water models: a molecular dynamics study. AB - The water confined within a surfactant bilayer is studied using different water models via molecular dynamics simulations. We considered four representative rigid models of water: the SPC/E and the TIP4P/2005, which are commonly used in numerical calculations and the more recent TIP4Q and SPC/epsilon models, developed to reproduce the dielectric behaviour of pure water. The static dielectric constant of the confined water was analyzed as a function of the temperature for the four models. In all cases it decreases as the temperature increases. Additionally, the static dielectric constant of the bilayer-water system was estimated through its expression in terms of the fluctuations in the total dipole moment, usually applied for isotropic systems. The estimated dielectric was compared with the available experimental data. We found that the TIP4Q and the SPC/epsilon produce closer values to the experimental data than the other models, particularly at room temperature. It was found that the probability of finding the sodium ion close to the head of the surfactant decreases as the temperature increases, thus the head of the surfactant is more exposed to the interaction with water when the temperature is higher.

AB - Multiphase CoCr2O4/Ni core-shell nanowires (NWs) have been synthesized within anodic aluminum oxide membranes by the combination of the sol-gel method with electrodeposition techniques. X-ray diffraction and x-ray photoemission spectroscopy results confirmed the formation of a cubic spinel structure of CoCr2O4 shell with space group Fd-3m (227). The morphology and composition of the as-grown NWs were studied by field emission scanning electron microscopy, as well as transmission electron microscopy. The magnetic properties of the CoCr2O4 NT shell and hybrid CoCr2O4/Ni NWs were measured at low temperature using a physical property measurement system. The temperature dependence of the magnetization curves showed that CoCr2O4 NTs undergo a transition from a paramagnetic state to a ferrimagnetic state at about 90 K and a spiral ordering transition temperature near 22 K. An enhanced coercivity and saturation field were observed for the CoCr2O4/Ni core-shell NWs compared to the single-phase Ni NWs. Micromagnetic simulation results indicated that there is a strong coupling between the shell and core layers during the magnetization reversal process. The combination of hard CoCr2O4 and soft Ni in a single NW structure may have potential applications in future multifunctional devices. PMID- 29583132 TI - Covalent functionalization of SWCNT with combretastatin A4 for cancer therapy. AB - Single walled carbon nanotubes (SWCNT) are currently under intensive investigation by many labs all over the world for being promising candidates for cancer chemotherapy delivery. On the other hand, combretastatin A4 (CA4) is an anticancer drug that induces cell apoptosis by inhibiting tubulin polymerization. However, it has the disadvantage of low water solubility and the non-selective targeting. Therefore, we aim to create nano-drug from the functionalization of SWCNT covalently with CA4 through click reaction in the presence of tetraethylene glycol linker in order to improve its dispersibility. Scanning electron microscopy and transmission electron microscopy showed good dispersibility of the functionalized SWCNT with diameters of 5-15 nm. Moreover, thermogravometric analysis showed that the efficiency of SWCNT functionalization was around 45%. The in vitro release profile of CA4 at physiological conditions showed that approximately 90% of the loaded drug was released over 50 h. After that MTS test was used to determine the suitable concentration range for the in vitro investigation of the SWCNT-CA4. After that the cytotoxic activity of the SWCNT CA4 was evaluated by flow cytometry using annexin V/propidium iodide (PI) test. In comparison with free CA4, SWCNT-CA4 treatment demonstrated a significant increase in necrotic cells (around 50%) at the expense of the proportion of the apoptotic cells. Moreover, cell cycle PI test demonstrated that free CA4 and SWCNT-CA4 caused G2/M arrest. However with CA4 treatment higher proportion of cells were in the S-phase while with SWCNT-CA4 treatment greater proportion of cells appeared to be in the G1-phase. Taken together, the provided data suggest that the novel SWCNT-CA4 has a significant anticancer activity that might be superior to that of free CA4.

AB - The dependence of the magnetocrystalline anisotropy energy (MAE) in MCo5 (M = Y, La, Ce, Gd) and CoPt on the Coulomb correlations and strength of spin orbit (SO) interaction within the GGA + U scheme is investigated. A range of parameters suitable for the satisfactory description of key magnetic properties is determined. We show that for a large variation of SO interaction the MAE in these materials can be well described by the traditional second order perturbation theory. We also show that in these materials the MAE can be both proportional and negatively proportional to the orbital moment anisotropy (OMA) of Co atoms. Dependence of relativistic effects on Coulomb correlations, applicability of the second order perturbation theory for the description of MAE, and effective screening of the SO interaction in these systems are discussed using a generalized virial theorem. Such determined sets of parameters of Coulomb correlations can be used in much needed large scale atomistic simulations. PMID- 29583134 TI - Super-resolution reconstruction of MR image with a novel residual learning network algorithm. AB - Spatial resolution is one of the key parameters of magnetic resonance imaging (MRI). The image super-resolution (SR) technique offers an alternative approach to improve the spatial resolution of MRI due to its simplicity. Convolutional neural networks (CNN)-based SR algorithms have achieved state-of-the-art performance, in which the global residual learning (GRL) strategy is now commonly used due to its effectiveness for learning image details for SR. However, the partial loss of image details usually happens in a very deep network due to the degradation problem. In this work, we propose a novel residual learning-based SR algorithm for MRI, which combines both multi-scale GRL and shallow network block based local residual learning (LRL). The proposed LRL module works effectively in capturing high-frequency details by learning local residuals. One simulated MRI dataset and two real MRI datasets have been used to evaluate our algorithm. The experimental results show that the proposed SR algorithm achieves superior performance to all of the other compared CNN-based SR algorithms in this work. PMID- 29583135 TI - 2D negative capacitance field-effect transistor with organic ferroelectrics. AB - In the past fifty years, complementary metal-oxide-semiconductor integrated circuits have undergone significant development, but Moore's law will soon come to an end. In order to break through the physical limit of Moore's law, 2D materials have been widely used in many electronic devices because of their high mobility and excellent mechanical flexibility. And the emergence of a negative capacitance field-effect transistor (NCFET) could not only break the thermal limit of conventional devices, but reduce the operating voltage and power consumption. This paper demonstrates a 2D NCFET that treats molybdenum disulfide as a channel material and organic P(VDF-TrFE) as a gate dielectric directly. This represents a new attempt to prepare NCFETs and produce flexible electronic devices. It exhibits a 10^6 on-/off-current ratio. And the minimum subthreshold swing (SS) of the 21 mV/decade and average SS of the 44 mV/decade in four orders of magnitude of drain current can also be observed at room temperature of 300 K.

Matter 29 445302) we have studied the effects of mechanical strain and magnetic field on the electronic transport properties in graphene. In this article we extended our work to Weyl semimetals (WSM). We show that although the WSM are 3D materials, most of the analysis done for graphene (2D material) can be carried out. In particular, we studied the electronic transport through a cylindrical region submitted to torsional strain and external magnetic field. We provide exact analytical expressions for the scattering cross section and the transmitted electronic current. In addition, we show the node-polarization effect on the current and propose a recipe to measure the torsion angle from transmission experiments.

AB - OBJECTIVE: An adequate level of fitness is critical to achieving healthy ageing. The aim of this study was to evaluate the impact of organized physical activity (PA) and the number of hours of practice on the fitness levels of the elderly. METHODS: A total of 3104 people over 65 years old from Spain, belonging to the EXERNET Multicenter Project (722 men and 2382 women, mean age: 72.1 +/- 5.3 years) participated in the study. Fitness was evaluated by 8 specific tests for this population. Participation in organized PA was recorded through a questionnaire. Differences in fitness values depending on the participation in PA and the number of hours were measured with ANCOVA adjusting for age, hours of walking and sitting time. RESULTS: Those who did not participate in this type of activity increased their risk of having a low level of fitness in most variables evaluated, with some differences between sexes (OR: from 1.6 to 2.6 in men and from 1.4 to 2.2 in women). In men, no significant differences were observed between practicing less than 2, 2-4 or more than 4 hours (P grater than 0,05), with an exception in the strength of the left arm. However, women who performed more than 2 hours a week in organized PA had better balance, strength of lower and upper extremities, flexibility of lower extremities, walking speed and aerobic capacity than those who performed less than 2 hours of PA a week (P less than 0,05). CONCLUSIONS: The practice of organized PA produces a beneficial effect on the fitness of the elderly regardless of age, hours of walking and time sitting per day.

AB - Streamflow data is highly relevant for a variety of socio-economic as well as ecological analyses or applications, but a high-resolution global streamflow dataset is yet lacking. We created FLO1K, a consistent streamflow dataset at a resolution of 30 arc seconds (~1 km) and global coverage. FLO1K comprises mean, maximum and minimum annual flow for each year in the period 1960-2015, provided as spatially continuous gridded layers. We mapped streamflow by means of artificial neural networks (ANNs) regression. An ensemble of ANNs were fitted on monthly streamflow observations from 6600 monitoring stations worldwide, i.e., minimum and maximum annual flows represent the lowest and highest mean monthly flows for a given year. As covariates we used the upstream-catchment physiography (area, surface slope, elevation) and year-specific climatic variables (precipitation, temperature, potential evapotranspiration, aridity index and seasonality indices). Confronting the maps with independent data indicated good agreement (R2 values up to 91%). FLO1K delivers essential data for freshwater ecology and water resources analyses at a global scale and yet high spatial resolution.

AB - We have developed a new coastal database for the Mediterranean basin that is intended for coastal impact and adaptation assessment to sea-level rise and associated hazards on a regional scale. The data structure of the database relies on a linear representation of the coast with associated spatial assessment units. Using information on coastal morphology, human settlements and administrative boundaries, we have divided the Mediterranean coast into 13 900 coastal assessment units. To these units we have spatially attributed 160 parameters on the characteristics of the natural and socio-economic subsystems, such as extreme sea levels, vertical land movement and number of people exposed to sea-level rise and extreme sea levels. The database contains information on current conditions and on plausible future changes that are essential drivers for future impacts, such as sea-level rise rates and socio-economic development. Besides its intended use in risk and impact assessment, we anticipate that the Mediterranean Coastal Database (MCD) constitutes a useful source of information for a wide range of coastal applications.

AB - Energy metering has gained popularity as conventional meters are replaced by electronic smart meters that promise energy savings and higher comfort levels for occupants. Achieving these goals requires a deeper understanding of consumption patterns to reduce the energy footprint: load profile forecasting, power disaggregation, appliance identification, startup event detection, etc. Publicly available datasets are used to test, verify, and benchmark possible solutions to these problems. For this purpose, we present the BLOND dataset: continuous energy measurements of a typical office environment at high sampling rates with common appliances and load profiles. We provide voltage and current readings for aggregated circuits and matching fully-labeled ground truth data (individual appliance measurements). The dataset contains 53 appliances (16 classes) in a 3 phase power grid. BLOND-50 contains 213 days of measurements sampled at 50kSps (aggregate) and 6.4kSps (individual appliances). BLOND-250 consists of the same setup: 50 days, 250kSps (aggregate), 50kSps (individual appliances). These are the longest continuous measurements at such high sampling rates and fully-labeled ground truth we are aware of.

AB - To meet researchers' increasing interest in the fast growing innovation activities taking place in China, we match patents filed with China's State Intellectual Property Office to firms covered in China's Census. China has experienced a strong growth in patent filings over the past two decades, and has since 2011 become the world's top patent filing country. China's Census database covers about one million unique manufacturing firms from 1998-2009, representing the broad Chinese economy. We design data parsing and pre-processing routines to clean and stem firm and assignee names, create a matching algorithm that fits with our data and maintains a balance between matching accuracy and workload of manual check, and implement a systematic manual check process to filter out false positives generated from computerized matching. Our project generates 1,113,588 matches for the Census firms, among which 849,647 patents are uniquely matched. By creating the patent-firm linked dataset, we hope to reduce duplicative effort and encourage more research to better understand China's fast changing innovation landscape.

AB - Light is an important environmental variable and most organisms have evolved means to sense, exploit or avoid it and to repair detrimental effects on their genome. In general, light absorption is the task of specific chromophores, however other biomolecules such as oligonucleotides also do so which can result in undesired outcomes such as mutations and cancer. Given the biological importance of light-induced processes and applications for imaging, optogenetics, photodynamic therapy or photovoltaics, there is a great interest in understanding the detailed molecular mechanisms of photoinduced processes in proteins and nucleic acids. The processes are typically characterized by time-resolved spectroscopic approaches or computation, inferring structural information on transient species from stable ground state structures. Recently, however, structure determination of excited states or other short-lived species has become possible with the advent of X-ray free-electron lasers. This review gives an overview of the impact of structure on the understanding of photoinduced processes in macromolecules, focusing on systems presented at this Faraday Discussion meeting.

AB - We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km2. The database originated from the collaboration of several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by the Istituto Nazionale di Geofisica e Vulcanologia. The observations were collected by performing detailed field surveys in the epicentral region in order to describe the geometry and kinematics of surface faulting, and subsequently of landslides and other secondary coseismic effects. The resulting database consists of homogeneous georeferenced records identifying 7323 observation points, each of which contains 18 numeric and string fields of relevant information. This database will impact future earthquake studies focused on modelling of the seismic processes in active extensional settings, updating probabilistic estimates of slip distribution, and assessing the hazard of surface faulting. PMID- 29583149 TI - Absolute cardiovascular risk of women using hormonal contraception in Porto-Novo. AB - INTRODUCTION: The purpose of this work was to determine the absolute cardiovascular risk (ACVR) of women using hormonal contraception in Porto-Novo. METHODS: We carried out a descriptive, cross-sectional study, including women at the time of renewal of a hormonal contraceptive method. Blood pressure, fasting venous blood glucose level, body mass index and electrocardiographic left ventricular hypertrophy were studied. The determination of ACVR was dual based on the World Health Organisation (WHO/ISH) and the European Society of Cardiology (ESC/ESH) models. RESULTS: The mean age of the women was 35.3 +/- 8.2 years. Blood pressure and blood glucose levels were high in 24 and 1.5% of cases, respectively. Left ventricular hypertrophy was present in 7.1% of cases. A high ACVR was found in 5.2% of these women, using the ESC/ESH model. CONCLUSION: The occurrence of women with high ACVR in this group raises the problem of cardiovascular eligibility to the contraceptive method used. PMID- 29583150 TI - Rheumatoid arthritis and risk of cardiovascular disease. AB - In developing countries, rheumatoid arthritis (RA) remains a seriously under prioritised disease, particularly among the underprivileged, often resulting in presentation of patients late in the course of their disease, further complicated by limited therapeutic options and inconsistent follow up. The consequences are often severe with irreversible disability, increased frequency of co-morbidities, especially cardiovascular disease (CVD), and higher mortality rates, relative to developed countries. Despite addressing traditional cardiovascular risk factors, the impact of subclinical or 'residual' inflammation from uncontrolled RA needs to be considered. This narrative review explores the prevalence and pathogenesis of CVD in RA, including the impact of tobacco use. It discusses pitfalls in the risk assessment of CVD in patients with RA, and the effect of disease-modifying anti-rheumatic therapy on cardiovascular co-morbidity. PMID- 29583151 TI - Ischaemic heart disease and pregnancy: the tale of two stories. AB - Ischaemic heart disease (IHD) is presumed to be rare in pregnancy. Based on that assumption, patients go undiagnosed or undertreated. IHD in pregnancy frequently occurs as a result of an unusual aetiology, therefore each patient needs to be managed individually since each may present differently. This may pose challenges to the consulting clinician. Pregnancy itself is a risk factor for cardiovascular disease, due to its associated hypercoagulable state. From current reports, the prevalence of IHD in females is increasing due to lifestyle changes, including cigarette smoking, diabetes and stress. In our modern societies, women delay childbearing until they are older, allowing time for risk factors to cluster. Although presumed to be rare in pregnant women, IHD is currently estimated to occur three to four times more often during pregnancy in middle- and high-income women, warranting an extensive review highlighting cases of IHD in pregnancy.

AB - After a brief introduction about the factors that are involved in science development, and world and Brazilian evolutionary genetics, the studies developed in Porto Alegre in this area were reviewed. Four periods in the development of this group were distinguished: (a) Origins and first expansion (1949-1961); (b) Second expansion (1962-1988); (c) Third expansion (1989-2001); and (d) The last 15 years (2002-present). The international Porto Alegre Biological Evolution Workshops (PABEWs), with five biannual events from 2007 o 2015, were also mentioned. The final message stressed the importance of the maintenance of this and other Brazilian groups of research through adequate finance and recognition. PMID- 29583153 TI - Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands. AB - The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within and among populations of the MOF-endemic bromeliad Vriesea reitzii by genotyping seven nuclear microsatellite loci in 187 individuals from six populations. We characterized levels of genetic diversity and assessed the genetic structure among populations. Vriesea reitzii populations showed high levels of genetic variation (number of alleles 28 - 43, allelic richness 3.589 - 5.531) and moderate levels of genetic differentiation (FST = 0.123, RST = 0.096). The high levels of genetic diversity may be explained by species life-history traits, such as habit and mating system. The moderate structure may be a product of the combination of ancient and contemporary gene flow, resulting from the expansion of the forest in the Holocene, and/or due to facilitated dispersal mediated by the MOF's mosaic landscape. The genetic results indicated no imminent threat to this bromeliad. However, the species is highly associated with the MOF, putting landscape conservation at the center of conservation efforts for the species' maintenance.

AB - The human C-C chemokine receptor type-5 (CCR5) is the major transmembrane co receptor that mediates HIV-1 entry into target CD4+ cells. Gene therapy to knock out the CCR5 gene has shown encouraging results in providing a functional cure for HIV-1 infection. In gene therapy strategies, the initial region of the CCR5 gene is a hotspot for producing functional gene knock-out. Such target gene editing can be done using programmable endonucleases such as transcription activator-like effector nucleases (TALEN) or clustered regularly interspaced short palindromic repeats (CRISPR-Cas9). These two gene editing approaches are the most modern and effective tools for precise gene modification. However, little is known of potential differences in the efficiencies of TALEN and CRISPR Cas9 for editing the beginning of the CCR5 gene. To examine which of these two methods is best for gene therapy, we compared the patterns and amount of editing at the beginning of the CCR5 gene using TALEN and CRISPR-Cas9 followed by DNA sequencing. This comparison revealed that CRISPR-Cas9 mediated the sorting of cells that contained 4.8 times more gene editing than TALEN+ transfected cells. PMID- 29583155 TI - Association between molecular markers and behavioral phenotypes in the immatures of a butterfly. AB - Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs. Previous work has estimated the heritability of kin recognition in H. erato phyllis to lie between 14 and 48%. It has furthermore been shown that the inheritance of kin recognition is compatible with a quantitative model with a threshold. Here we present the results of a preliminary study, in which we tested for associations between behavioral kin recognition phenotypes and AFLP and SSR markers. We implemented two experimental approaches: (1) a cannibalism test using sibling eggs only, which allowed for only two behavioral outcomes (cannibal and non-cannibal), and (2) a cannibalism test using two sibling eggs and one unrelated egg, which allowed four outcomes [cannibal who does not recognize siblings, cannibal who recognizes siblings, "super-cannibal" (cannibal of both eggs), and "super non-cannibal" (does not cannibalize eggs at all)]. Single-marker analyses were performed using chi2 tests and logistic regression with null markers as covariates. Results of the chi2 tests identified 72 associations for experimental design 1 and 73 associations for design 2. Logistic regression analysis of the markers found to be significant in the chi2 test resulted in 20 associations for design 1 and 11 associations for design 2. Experiment 2 identified markers that were more frequently present or absent in cannibals who recognize siblings and super non-cannibals; i.e. in both phenotypes capable of kin recognition.

AB - sn-Glycerol-3-phosphate 1-O-acyltransferase (GPAT) is an important enzyme that catalyzes the transfer of an acyl group from acyl-CoA or acyl-ACP to the sn-1 or sn-2 position of sn-glycerol-3-phosphate (G3P) to generate lysophosphatidic acids (LPAs). The functional studies of GPAT in plants demonstrated its importance in controlling storage and membrane lipid. Identifying genes encoding GPAT in a variety of plant species is crucial to understand their involvement in different metabolic pathways and physiological functions. Here, we performed genome-wide and evolutionary analyses of GPATs in plants. GPAT genes were identified in all algae and plants studied. The phylogenetic analysis showed that these genes group into three main clades. While clades I (GPAT9) and II (soluble GPAT) include GPATs from algae and plants, clade III (GPAT1-8) includes GPATs specific from plants that are involved in the biosynthesis of cutin or suberin. Gene organization and the expression pattern of GPATs in plants corroborate with clade formation in the phylogeny, suggesting that the evolutionary patterns is reflected in their functionality. Overall, our results provide important insights into the evolution of the plant GPATs and allowed us to explore the evolutionary mechanism underlying the functional diversification among these genes.

AB - The aim of this case-case study was to determine the differences between dysplastic and common naevus-associated melanomas (NAM) and de novo melanomas. A total of 1,021 prospectively collected patients with invasive cutaneous melanoma from an oncology referral centre were included in the study. Of these, 75.51% had de novo melanomas, 12.93% dysplastic NAM, and 11.56% common NAM. Dysplastic NAM, compared with de novo melanomas, were associated with intermittently photo exposed sites, atypical melanocytic naevi, decreased tumour thickness, and presence of MC1R non-synonymous variants. Common NAM were more frequent on the trunk and of superficial spreading type. Comparison of dysplastic with common NAM showed significant difference only with regard to mitoses. Both subtypes of NAM shared less aggressive traits than de novo melanomas, albeit with no significant differences in survival after multivariate adjustment. In conclusion, NAM present with less aggressive traits, mostly due to a greater awareness among patients of changing moles than due to their intrinsic biological characteristics.

AB - Amyloidosis is a disease complex characterized by the deposition of protein fibrils in various tissues, which leads to structural and functional derangement of the affected organ. There are different types of amyloidosis categorized on the basis of the type of protein fibrils deposited. Cardiac involvement has been predominantly noted in amyloid light chain (AL) amyloidosis and is the major prognostic determinant and influences the therapeutic strategy. In AL amyloidosis, heart transplantation is generally not recommended because of a high risk of recurrence in the transplanted heart and poor survival rate. However, a favourable outcome can be achieved if heart transplantation is followed by an autologous stem cell transplantation (ASCT). We describe our experience from the two first patients with AL amyloidosis treated with heart transplantation and subsequent ASCT at Sahlgrenska University Hospital. PMID- 29583160 TI - ?

AB - A working group representing the Swedish Society for Infectious Diseases, the Swedish Society for Anaesthesiology and Intensive Care, the Swedish Society for Emergency Medicine, and the Swedish Intensive Care Registry have reached consensus on how to adopt the new sepsis definition, Sepsis-3, in Sweden. The recommendation is to implement the new definitions and diagnostic criteria for sepsis and septic shock, but not the use of the new screening tool for sepsis, quick-SOFA, as it needs prospective validation and since it is not clear if quick SOFA is more useful than the currently used general triage and early warning score systems. The group recommends the use of the sfollowing ICD-10 codes: R65.1 for sepsis and R57.2 for septic shock. PMID- 29583162 TI - ? PMID- 29583164 TI - ? PMID- 29583163 TI - ? PMID- 29583165 TI - ?

AB - Cardiac arrest is a traumatic event, both for patients and their family members. Traditionally, healthcare professionals have often been reluctant to offer family members the opportunity to witness cardiopulmonary resuscitation (CPR) attempts. However, professional bodies globally have begun to recommend the use of family witnessed resuscitation (FWR) during CPR, identifying a range of potential benefits including supporting the patient, increasing family members' confidence in healthcare professionals and, in some cases, promoting acceptance of the patient's death. This article explores the benefits of, and barriers to, the implementation of FWR during CPR. Despite the perceived benefits of FWR identified by professional bodies, healthcare professionals, and patients and their families, the evidence indicates there is ongoing reluctance among some healthcare professionals to incorporate FWR in practice. Therefore, standardised global policies aimed at the multidisciplinary implementation of FWR are required. Additionally, multidisciplinary training and education in CPR should be readily available, particularly in areas where CPR is frequently used, such as emergency departments. PMID- 29583169 TI - An overview of developments in nurse prescribing in the UK. AB - In the UK and internationally, the nursing profession is continuing to advance and innovate its roles and functions. One area in which this is particularly notable is nurse prescribing. The UK has the most extended nurse prescribing rights in the world, with significant advances in this field over the past two decades. This article reflects on this development, what has been learned and the challenges that remain in relation to nurse prescribing and meeting healthcare service needs. PMID- 29583170 TI - Identification and management of drug allergy. AB - This article describes the signs and symptoms of drug allergy, and explains the effects that it can have on patient care. It outlines the risk factors for the development of drug allergy, along with the mechanisms by which allergic reactions are mediated. This article also explains the tests used to diagnose drug allergy, and provides recommendations for the management of patients who experience an allergic reaction to a drug. The author uses case studies to emphasise the importance of the role of the nurse in managing, reporting and documenting drug allergies appropriately. PMID- 29583171 TI - Meeting the needs of carers of people at the end of life. AB - Carers have a vital role in end of life care in all settings. They are essential in enabling people to live at home at the end of their lives. Carers give and receive care, and have a range of support needs related to this complex role. This article explores the context of caring at the end of life and considers the experience of carers, in particular those who have a non-professional and unpaid relationship with someone who is at the end of life, and the support they require. PMID- 29583172 TI - Collaborative communication: learning from advanced clinical practice patient consultations. AB - Advanced nurse practitioners, and nurses aspiring to this role, are required to understand how to communicate effectively and on a collaborative basis with patients and carers during consultations, with the aim of enhancing patient outcomes such as improved patient satisfaction, ability to self-manage healthcare needs and adherence to care plans. This article explores collaborative communication in consultations and how best to achieve this, using the author's doctoral observational research based on the findings of a mixed methods observational study of communication in advanced clinical practice patient consultations.

AB - A teenager with a problem of substance abuse or dependence to social media does not usually realize and tends to minimize the consequences, until the problems related to its use and consumption appear. We may understand that this is a sick person who needs help and with full right to be assisted without any restrictions. During the health care activities with these patients, professionals are often involved in situations in which decision-making does not involve just assessing health aspects, but also the legal and ethical implications. Thus, we deal with some ethical issues that affect to our activity and the quality of care.

AB - Introduction: The emergency centers for primary care (CUAP, for its acronym in Spanish) are created in order to address low and medium emergency pathologies. Nurses resolve low emergency acute minor illness, through performance algorithms which increase their resolutions. Objectives: The main objective is to describe acute minor illness in adults solved by nurses at the Manso CUAP trough performance algorithms. Justification: The involvement of nurses in the care for acute minor illness at the CUAPs strengthens their service portfolio and places them at the gateway of the health system. Performance algorithms provide nurses with the ability to manage up to the end the resolution of the user's demand. Material and Method: Data collection was carried out for 6 months, during increased pressure flows, analyzing the use of 20 performance algorithms. Data was extracted from computerized medical records. Resutls: Health problems were solved in 1575 patients with an average age of 40 years. The consultations most frequently resolved by the nurses were: injuries (27%), application of techniques (20 %) and health education (13 %). Conclusions: The use of performance algorithms for decision-making is effective for acute minor illness nurse care. Health education can solve a high performance of queries.

AB - Objective: To explore the use of health services in the Spanish population, according health insurance. Methods: A cross-sectional study using data from the Spanish National Health Survey 2011-2012 was conducted. 21 007 people were included. Among individuals with health coverage, three groups were differentiated: people with public, private and mixed insurance. Univariate and bivariate analyses were developed to know health services and bivariate analyses were developed to know health services use differences by health insurance. Results: 83.5 % of the population reported only a public coverage, 2.5 % has only private insurance and 14 % was enrolled in both forms. Individuals with public coverage visited with higher frequency the general physician (81.9 %), while those with only private insurance visited a specialist in the highest proportion (65.6 %). Individuals with only public health coverage presented the longest waiting times, for both programmed hospitalization and medical attention. In general terms, people with double coverage showed the greatest participation in preventive activities. Conclusions: Public coverage is the most important coverage of the Spanish population. Different use of health resources were observed according to health insurance. PMID- 29583177 TI - Exhibition of Instrument.

AB - Introduction: The obstetric violence (OV) is the type of violence perpetrated against the pregnant woman through acts such as lack of respect to her autonomy and her freedom to decide. The increasing medicalization of the labour process, seems to be associated to this type of violence. Objective: Our objective is to provide health professionals with the necessary knowledge to be able to inform their patients about their rights and recognize those situations that can imply violence during the care process. Material and methods: The literature search was conducted in the following databases: PubMed, Cochrane Database of Systematic Reviews, EMBASE, Joanna Briggs Institute, UpToDate and CUIDEN. The search was limited to articles published during the last five years. The next medical subject heading were used both in English and Spanish: "humanizing delivery", "obstetrics", "medicalization" and "violence". Results: The performance of harmful practices and the unjustified medicalization of the labour process represent a potential damage to pregnant women by action, violating their rights as a result. To prevent and eradicate this, new lines of less interventionist work are being proposed. Conclusion: As health professionals we should promote the humanization of labour and informs women about the existent legislation, protocols and guidelines that offer adequate information based on the latest evidence and promote their advance role as patients. The health institutions are responsible for initiating this change, by implementing protocols to guide the practice of the health professionals involved in the care of women during labour. These protocols should be based on the WHO recommendations. PMID- 29584392 TI - [Fundamental aspects in the choice of renal replacement therapy]. AB - Chronic kidney disease (CKD) is a disease with a high prevalence in our environment, and those suffering the disease should be as clear as possible that renal replacement therapy (RRT) may better suit your lifestyle. It is important that the patient has enough information about the techniques that can be accessed in a clear manner, so as to evaluate the different possibilities, advantages and disadvantages. The timing on this election is crucial and stressful for the patient's life, not only by the effects of the disease itself, but also by the assimilation of a new lifestyle that should keep the rest of it.This work was done thinking about the need for patients and health professionals in acquiring a holistic and comprehensive understanding of all the features that can have both peritoneal dialysis (PD) and hemodialysis (HD); form own patient factors (diet, family environment, etc.) related to nurses (care, information provided, etc.) without forgetting the conditions outside the patient and the nurse as they can be structural and economic aspects. PMID- 29584394 TI - ?Que entendemos hoy por formarse? PMID- 29584393 TI - [Elderly caregivers of elderly people]. AB - The ageing of the population is a reality in our society nowadays. The aging process changes increase the probability that health problems occur. This fact involves that the needs of care demanded by the population increase too. The care for the elderly generally are provided in home environments, where often, the primary caregiver is another old person. In this sense, must be taken into account that this stage of life, the old age, although there has been important improvements in the quality of life and in the resolution of health problems, presents certain limitations refers to physical and mental declines that affect to the functional capacity of elderly caregivers. For this reason, it is necessary to carry out a comprehensive geriatric assessment to identify unresolved needs and establish care strategies required to attend their demands for care. PMID- 29584395 TI - pi-Extended Benzoporphyrin-Based Metal-Organic Framework for Inhibition of Tumor Metastasis. AB - We report on the benzoporphyrin-based metal-organic framework (TBP-MOF), with 10 connected Zr6 cluster and much improved photophysical properties over the traditional porphyrin-based MOFs. It was found that TBP-MOF exhibited red-shifted absorption bands and strong near-infrared luminescence for bioimaging, whereas the pi-extended benzoporphyrin-based linkers of TBP-MOF facilitated 1O2 generation to enhance O2-dependent photodynamic therapy (PDT). It was demonstrated that poly(ethylene glycol)-modified nanoscale TBP-MOF (TBP-nMOF) can be used as an effective PDT agent under hypoxic tumor microenvironment. We also elucidated that the low O2-dependent PDT of TBP-nMOF in combination with alphaPD 1 checkpoint blockade therapy can not only suppress the growth of primary tumor, but also stimulate an antitumor immune response for inhibiting metastatic tumor growth. We believe this TBP-nMOF has great potential to serve as an efficient photosensitizer for PDT and cancer immunotherapy. PMID- 29584396 TI - Cooperative Assembly of a Peptide Gelator and Silk Fibroin Afford an Injectable Hydrogel for Tissue Engineering. AB - Silk fibroin (SF) from Bombyx mori has received increasing interest in biomedical fields, because of its slow biodegradability, good biocompatibility, and low immunogenicity. Although SF-based hydrogels have been studied intensively as a potential matrix for tissue engineering, weak gelation performance and low mechanical strength are major limitations that hamper their widespread applicability. Therefore, searching for new strategies to improve the SF gelation property is highly desirable in tissue engineering research. Herein, we report a facile approach to induce rapid gelation of SF by a small peptide gelator (e.g., NapFF). Following the simple mixing of SF and NapFF in water, a stable hydrogel of SF was obtained in a short time period at physiological pH, and the minimum gelation concentration of SF can reach as low as 0.1%. In this process of gelation, NapFF not only can behave itself as a gelator for supramolecular self assembly, but also can trigger the conformational transition of the SF molecule from random coil to beta-sheet structure via hydrophobic and hydrogen-bonding interactions. More importantly, for the generation of a scaffold with favorable cell-surface interactions, a new peptide gelator (NapFFRGD) with Arg-Gly-Asp (RGD) domain was applied to functionalize SF hydrogel with improved bioactivity for cell adhesion and growth. Following encapsulating the vascular endothelial growth factor (VEGF), the SF gel was subcutaneously injected in mice, and served as an effective matrix to trigger the generation of new blood capillaries in vivo.

AB - Methylammonium (MA) lead halide (MAPbX3, X = Cl, Br, I) perovskite quantum dots (PQDs) are very sensitive to environment (moisture, oxygen, and temperature), suffering from poor stability. To improve the stability, we synthesized silica coated PQDs (SPQDs) by an improved ligand-assisted reprecipitation method through simply mixing and stirring under room temperature in air without adding water and catalyst, the whole process took only a few seconds. The photoluminescence (PL) spectra of the SPQDs can be tuned continuously from 460 to 662 nm via adjusting the composition proportion of precursors. The highest PL quantum yields (PLQYs) of blue-, green-, and red-emissive SPQDs are 56, 95, and 70%, respectively. The SPQDs show remarkably improved environmental and thermal stability compared to the naked PQDs because of effective barrier created by the coated silica between the core materials and the ambience. Furthermore, it is found that different light-emitting SPQDs can maintain their original PL properties after mixing of them and anion-exchange reactions have not happened. These attributes were then used to mix green- and yellow-emissive SPQDs with polystyrene (PS) to form color converting layers for the fabrication of white light-emitting devices (WLEDs). The WLEDs exhibit excellent white light characteristics with CIE 1931 color coordinates of (0.31, 0.34) and color rendering index (CRI) of 85, demonstrating promising applications of SPQDs in lighting and displays. PMID- 29584398 TI - A Biomimetic Conductive Tendril for Ultrastretchable and Integratable Electronics, Muscles, and Sensors. AB - Adaptive tendril coiling of climbing plants has long inspired the artificial soft microsystem for actuation and morphing. The current bionic research efforts on tendril coiling focus on either the preparation of materials with the coiling geometry or the design of self-shaping materials. However, the realization of two key functional features of the tendril, the spring-like buffering connection and the axial contraction, remains elusive. Herein, we devise a conductive tendril by fusing conductive yarns into tendril configuration, bypassing the prevailing conductivity constraints and mechanical limitations. The conductive tendril not only inherits an electrophysiology buffering mechanics with exceptional conductance retention ability against extreme stretching but also exhibits excellent contractive actuation performance. The integrative design of the ultraelastic conductive tendril shows a combination of compliant mobility, actuation, and sensory capabilities. Such smart biomimetic material holds great prospects in the fields of ultrastretchable electronics, artificial muscles, and wearable bioelectronic therapeutics. PMID- 29584400 TI - Thieno[3,2- b]pyrrole-benzothiadiazole Banana-Shaped Small Molecules for Organic Field-Effect Transistors. AB - We report two banana-shaped organic semiconducting small molecules containing the relatively unexplored thieno[3,2- b]pyrrole with thiophene and furan flanked benzothiadiazole. Theoretical insights gained by DFT calculations, supported by single crystal structures show that furan flanked benzothiadiazole-thieno[3,2- b]pyrrole small molecule has a higher curvature compared to the thiophene flanked small molecule due to the shorter carbon-oxygen bond in furan. Despite similar optical and electrochemical properties, thiophene flanked small molecule shows average hole mobility up to 8 * 10-2 cm2 V-1 s-1, however furan flanked small molecule performs poorly in thin film transistor devices (MUh ~ 5 * 10-6 cm2 V-1 s-1). The drastic difference in hole mobilities was due to the annealing-induced crystallinity which was demonstrated by the out-of-plane grazing incidence X-ray diffraction and surface morphology studies by tapping mode atomic force microscopy analysis. PMID- 29584399 TI - Targeted Quantification of Phosphorylation Dynamics in the Context of EGFR-MAPK Pathway. AB - Large-scale phosphoproteomics with coverage of over 10,000 sites of phosphorylation have now been routinely achieved with advanced mass spectrometry (MS)-based workflows. However, accurate targeted MS-based quantification of phosphorylation dynamics, an important direction for gaining quantitative understanding of signaling pathways or networks, has been much less investigated. Herein, we report an assessment of the targeted workflow in the context of signal transduction pathways, using the epidermal growth factor receptor (EGFR)-mitogen activated protein kinase (MAPK) pathway as our model. A total of 43 phosphopeptides from the EGFR-MAPK pathway were selected for the study. The recovery and sensitivity of two commonly used enrichment methods, immobilized metal affinity chromatography (IMAC) and titanium oxide (TiO2), combined with selected reaction monitoring (SRM)-MS were evaluated. The recovery of phosphopeptides by IMAC and TiO2 enrichment was quantified to be 38 +/- 5% and 58 +/- 20%, respectively, based on internal standards. Moreover, both enrichment methods provided comparable sensitivity from 1 to 100 MUg starting peptides. Robust quantification was consistently achieved for most targeted phosphopeptides when starting with 25-100 MUg peptides. However, the numbers of quantified targets significantly dropped when peptide samples were in the 1-25 MUg range. Finally, IMAC-SRM was applied to quantify signaling dynamics of EGFR-MAPK pathway in Hs578T cells following 10 ng/mL EGF treatment. The kinetics of phosphorylation clearly revealed early and late phases of phosphorylation, even for very low abundance proteins. These results demonstrate the feasibility of robust targeted quantification of phosphorylation dynamics for specific pathways, even starting with relatively small amounts of protein. PMID- 29584402 TI - Organic Solvent as Internal Standards for Quantitative and High-Throughput Liquid Interfacial SERS Analysis in Complex Media. AB - Liquid-state interfacial nanoparticle arrays for surface-enhanced Raman scattering (SERS) promises a practical, substrate-free, and rapid analysis but faces a great challenge to develop a batch and uniform fabrication strategy with stable internal standards (IS) because of the difficulties in precisely locating both the IS tags and analytes in the same local structure under the harsh conditions of biphasic liquid interface. Here, we develop a fast batch preparation of self-ordered dense Au nanoparticle (GNP) arrays on cyclohexane/water biphasic interface in 96-well plates with the assist of acetone as the phase-crossing inducer. The acetone can extract the pesticide molecules via a simple dipping sample peels and can rapidly capture and locate the pesticide molecule into the plasmonic hotspots. Meanwhile, this phase-crossing solvent, acetone itself, generates stable SERS signal and is used as the IS tags to calibrate the signal fluctuation. This platform presents an excellent uniformity with a relative standard deviation (RSD) of 5.9% compared to the RSD of 14.5% without the IS's correction and a good sensitivity with a limit of detection (LOD) of 1 nM thiram. This high-throughput strategy for analyzing pesticide residues at fruit peels reached detection levels of nanograms per square centimeter (ng/cm2). Combined with the 96-well plates, this platform greatly facilitates the self-assembly and multiplex sampling. The self-ordered arrays at two immiscible phases interface evidenced the detection of both the oil soluble thiabendazole and the water-soluble thiram molecules and also realized the multiplex and two-phase detection of these two pesticides. This platform offers vast possibilities for on-site sensing of various analytes and paves a new way for the quantitative and high-throughput SERS analyzer just as convenient as the microplate reader. PMID- 29584404 TI - Dual-Valve and Counter-Flow Surface Plasmon Resonance. AB - Two six-port injector valves and one selector valve commonly used in flow injection analysis are combined with a surface plasmon resonance (SPR) instrument wherein solutions introduced from the two inlets counter-flow inside the flow cell. The system is versatile as the same or different solutions can be rapidly and repeatedly introduced to the two fluidic channels in series or in parallel. Unlike most commercial SPR instruments employing a single injector valve, solutions separately injected from the two injector valves can be readily exchanged (<1 s) between the two channels. This new method, referred to as the alternate injection mode, not only saves analysis time but also facilitates efficient and facile surface reactions for ligand immobilization and prevents immobilized species from desorbing. These advantages are demonstrated with the measurements of binding of acetazolamide (222.2 Da) to histidine-tagged human carbonic anhydrase II (his-tagged HCA). Amine-containing residues of his-tagged HCA molecules tethered at Ni-nitrilotriacetic acid (NTA) sensors were rapidly cross-linked to the underlying carboxymethylated dextran. The higher ligand densities and more stable surfaces are essential for SPR detection of small molecule binding. In a different application, microglobulin solutions of increasing concentrations were introduced for continuous binding to the preimmobilized antibody. The kinetic and affinity measurements can be conducted without performing repeated dissociation and surface regeneration reactions. PMID- 29584406 TI - Plug-and-Play Multicellular Circuits with Time-Dependent Dynamic Responses. AB - Synthetic biology studies aim to develop cellular devices for biomedical applications. These devices, based on living instead of electronic or electromechanic technology, might provide alternative treatments for a wide range of diseases. However, the feasibility of these devices depends, in many cases, on complex genetic circuits that must fulfill physiological requirements. In this work, we explored the potential of multicellular architectures to act as an alternative to complex circuits for implementation of new devices. As a proof of concept, we developed specific circuits for insulin or glucagon production in response to different glucose levels. Here, we show that fundamental features, such as circuit's affinity or sensitivity, are dependent on the specific configuration of the multicellular consortia, providing a method for tuning these properties without genetic engineering. As an example, we have designed and built circuits with an incoherent feed-forward loop architecture (FFL) that can be easily adjusted to generate single pulse responses. Our results might serve as a blueprint for future development of cellular devices for glycemia regulation in diabetic patients. PMID- 29584407 TI - Polyelectrolyte Complex Inclusive Biohybrid Microgels for Tailoring Delivery of Copigmented Anthocyanins. AB - This study fabricated a novel biohybrid microgel containing polysaccharide-based polyelectrolyte complexes (PECs) for anthocyanins. Herein, anthocyanins were encapsulated into PECs composed of chondroitin sulfate and chitosan, followed by incorporation into alginate microgels using emulsification/internal gelation method. We demonstrated that PECs incorporation strongly affected the properties of microgels, dependent on the polysaccharide concentration and pH in which they were fabricated. The dense internal network surrounded by an alginate shell was clearly visualized in cross-sectioned PECs-microgels. Stability studies carried out under varying ionic strength and pH conditions demonstrated the stimuli responsiveness of the PECs-microgels. Additionally, the presence of PECs conferred microgels with high rigidity during freeze-drying and excellent reconstitution capacity upon rehydration. These observations were attributed to the modulation of electrostatic and hydrogen-bonding cross-linking between PECs and the alginate gel matrix and suggest the PECs inclusive microgels hold promise as delivery vehicles for the controlled release of hydrophilic bioactive compounds. PMID- 29584408 TI - Seasonal Dynamics of Glyphosate and AMPA in Lake Greifensee: Rapid Microbial Degradation in the Epilimnion During Summer. AB - Occurrence and fate of glyphosate, a widely used herbicide, and its main metabolite AMPA was investigated in Lake Greifensee, Switzerland. Monthly vertical concentration profiles in the lake showed an increase of glyphosate concentrations in the epilimnion from 15 ng/L in March to 145 ng/L in July, followed by a sharp decline to <5 ng/L in August. A similar pattern was observed for AMPA. Concentrations of glyphosate and AMPA in the two main tributaries generally were much higher than in the lake. Simulations using a numerical lake model indicated that a substantial amount of glyphosate and AMPA dissipated in the epilimnion, mainly in July and August, with half-lives of only ~2-4 days which is ?100 times faster than in the preceding months. Fast dissipation coincided with high water temperatures and phytoplankton densities, and low phosphate concentrations. This indicates that glyphosate might have been used as an alternative phosphorus source by bacterio- and phytoplankton. Metagenomic analysis of lake water revealed the presence of organisms known to be capable of degrading glyphosate and AMPA. PMID- 29584409 TI - The Structural Basis of Calcium-Dependent Inactivation of the Transient Receptor Potential Vanilloid 5 Channel. AB - The transient receptor potential vanilloid channel subfamily member 5 (TRPV5) is a highly selective calcium ion channel predominately expressed in the kidney epithelium that plays an essential role in calcium reabsorption from renal infiltrate. In order to maintain Ca2+ homeostasis, TRPV5 possesses a tightly regulated negative feedback mechanism, where the ubiquitous Ca2+ binding protein calmodulin (CaM) directly binds to the intracellular TRPV5 C-terminus, thus regulating TRPV5. Here we report on the characterization of the TRPV5 C-terminal CaM binding site and its interaction with CaM at an atomistic level. We have solved the de novo solution structure of the TRPV5 C-terminus in complex with a CaM mutant, creating conditions that mimic the cellular basal Ca2+ state. We demonstrate that under these conditions the TRPV5 C-terminus is exclusively bound to the CaM C-lobe only, while it confers conformational freedom to the CaM N lobe. We also show that at elevated calcium levels, additional interactions between the TRPV5 C-terminus and CaM N-lobe occur, resulting in formation of a tight 1:1 complex, effectively making the N-lobe the calcium sensor. Together, these data are consistent with and support the novel model for Ca2+/CaM-dependent inactivation of TRPV channels as proposed by Bate and co-workers [ Bate , N. , et al. ( 2018 ) Biochemistry , ( 57), DOI: 10.1021/acs.biochem.7b01286 ]. PMID- 29584410 TI - A Universal Approach to Render Nanomedicine with Biological Identity Derived from Cell Membranes. AB - Biomimetic nanoengineering built through integrating the specific cell membrane with artificially synthetic nanomedicines represents one of the most promising directions for the actualization of personalized therapy. For addressing the technical hurdle against the development of this biomimetic technology, the present report describes the in-depth exploration and optimization over each critical preparation step, including establishment of a nanoparticle-stabilized dispersion system, cargo loading, membrane coating, and product isolation. Magnetic iron oxide nanoparticles loaded with DOX is used as a typical model for the coating with cancer cell membranes, providing compact DNP@CCCM nanostructure well-characterized by various techniques. Furthermore, the feasibility of this optimized approach in constructing biomimetic membrane-coated nanomedicines has been validated on the basis of the remarkably improved biofunctions, such as the targetability, magnetic property, hemolysis risk, macrophage evasion, in vitro cytotoxicity, in vivo circulation duration, and in vivo principal component analysis postinjection. We hope this study regarding technique optimization will prompt the advancement of biomembrane-camouflaged nanoparticles as a newly emerging biomimetic technology.

AB - The high activity of exposed facets and large surface area have significant effects on the performance of photocatalysts because most of the photoreactivity properties of materials are related to surface processes. The strategy of combining high-index facets and a hollow structure into one material will provide a new way for designing effective photocatalysts, possessing active exposed facets and a large surface area at the same time. However, fabricating one material with both high-index facets and a hollow structure is still a great challenge due to their thermodynamic instability. Here, hollow anatase TiO2 octahedrons exposed with high-index (102) facets (HTO-102) were successfully fabricated for the first time by a facile hydrothermal method using HF and H2O2 as morphology controlling agents. Compared with two other catalysts (a solid sharp octahedron with (101) facets (SSO-101) and a hollow sharp octahedron with (101) facets (HSO-101)), HTO-102 particles exhibit a better photochemical activity for the selective aerobic oxidation of organic sulfides under visible light irradiation. Experimental results and theoretical calculations indicate that the excellent photocatalytic activity of HTO-102 particles is mainly due to the synergistic effects of its hollow structure and exposed high-index (102) facets. PMID- 29584416 TI - Photoswitchable Micelles for the Control of Singlet-Oxygen Generation in Photodynamic Therapies. AB - Inadvertent photosensitizer-activation and singlet-oxygen generation hampers clinical application of photodynamic therapies of superficial tumors or subcutaneous infections. Therefore, a reversible photoswitchable system was designed in micellar nanocarriers using ZnTPP as a photosensitizer and BDTE as a photoswitch. Singlet-oxygen generation upon irradiation didnot occur in closed switch micelles with ZnTPP/BDTE feeding ratios >1:10. Deliberate switch closure/opening within 65-80 min was possible through thin layers of porcine tissue in vitro, increasing for thicker layers. Inadvertent opening of the switch by simulated daylight, took several tens of hours. Creating deliberate cell damage and prevention of inadvertent damage in vitro and in mice could be done at lower ZnTPP/BDTE feeding ratios (1:5) in open-switch micelles and at higher irradiation intensities than inferred from chemical clues to generate singlet oxygen. The reduction of inadvertent photosensitizer activation in micellar nanocarriers, while maintaining the ability to kill tumor cells and infectious bacteria established here, brings photodynamic therapies closer to clinical application. PMID- 29584417 TI - Exploiting Ring-Opening Aminolysis-Condensation as a Polymerization Pathway to Structurally Diverse Biobased Polyamides. AB - A pathway to biobased polyamides (PAs) via ring-opening aminolysis-condensation (ROAC) under benign conditions with diverse structure was designed. Ethylene brassylate (EB), a plant oil-derived cyclic dilactone, was used in combination with an array of diamines of diverse chemical structure, and ring-opening of the cyclic dilactone EB was revealed as a driving force for the reaction. The ROAC reactions were adjusted, and reaction conditions of 100 degrees C under atmospheric pressure using 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as a catalyst for 24 h were optimal. The structures of the polyamides were confirmed by mass spectroscopy, FTIR, and NMR, and the PAs had viscosity average molecular weights ( Meta) of ~5-8 kDa. Glassy or semicrystalline PAs with glass transition temperatures between 48 and 55 degrees C, melting temperatures of 120-200 degrees C for the semicrystalline PAs, and thermal stabilities above 400 degrees C were obtained and were comparable to the existing PAs with similar structures. As a proof-of-concept of their usage, one of the PAs was shown to form fibers by electrospinning and films by melt pressing. Compared to conventional methods for PA synthesis, the ROAC route portrayed a reaction temperature at least 60-80 degrees C lower, could be readily carried out without a low-pressure environment, and eliminated the use of solvents and toxic chemicals. Together with the plant oil-derived monomer (EB), the ROAC route provided a sustainable alternative to design biobased PAs. PMID- 29584419 TI - A Comparative Proteome Approach Reveals Metabolic Changes Associated with Flammulina velutipes Mycelia in Response to Cold and Light Stress. AB - In some industrial processes, cold and light stresses are recognized as two important environmental triggers for the transformation of mycelia into fruit bodies via intermediate primordia in Flammulina velutipes cultivation. To gain insights into the mechanism of regulation of F. velutipes mycelia in response to cold and light stress, proteins expressed abundantly and characteristically at particular stress states were investigated by using the isobaric tags for the relative and absolute quantitation labeling technique. Among the 1046 nonredundant proteins identified with a high degree of confidence, 264 proteins, which were detected as differentially expressed proteins, were associated with 176 specific KEGG pathways. In-depth data analysis revealed that the regulatory network underlying the cold and light response mechanisms of F. velutipes mycelia was complex and multifaceted, as it included varied functions such as rapid energy supply, the biosynthesis of lysine, phenylalanine, tyrosine, and gamma aminobutyric acid, the calcium signal transduction process, dynein-dependent actin and microtubule cytoskeleton formation, autolysis, oxidative stress adaptation, pigment secretion, tissue and organ morphogenesis, and other interesting stress-related processes. Insights into the proteins might shed light on an intuitive understanding of the cold and light stress response mechanism underlying the fruiting processes of F. velutipes. Furthermore, the data might also provide further insights into the stress response mechanism of macro-fungi and valuable information for scientific improvement of some mushroom cultivation techniques in practice. PMID- 29584421 TI - Benzoxazole-Linked Ultrastable Covalent Organic Frameworks for Photocatalysis. AB - The structural uniqueness of covalent organic frameworks (COFs) has brought these new materials great potential for advanced applications. One of the key aspects yet to be developed is how to improve the robustness of covalently linked reticular frameworks. In order to make the best use of pi-conjugated structures, we develop herein a "killing two birds with one stone" strategy and construct a series of ultrastable benzoxazole-based COFs (denoted as LZU-190, LZU-191, and LZU-192) as metal-free photocatalysts. Benefiting from the formation of benzoxazole rings through reversible/irreversible cascade reactions, the synthesized COFs exhibit permanent stability in the presence of strong acid (9 M HCl), strong base (9 M NaOH), and sunlight. Meanwhile, reticulation of the benzoxazole moiety into the pi-conjugated COF frameworks decreases the optical band gap and therefore increases the capability for visible-light absorption. As a result, the excellent photoactivity and unprecedented recyclability of LZU-190 (for at least 20 catalytic runs, each with a product yield of 99%) have been illustrated in the visible-light-driven oxidative hydroxylation of arylboronic acids to phenols. This contribution represents the first report on the photocatalytic application of benzoxazole-based structures, which not only sheds new light on the exploration of robust organophotocatalysts from small molecules to extended frameworks but also offers in-depth understanding of the structure activity relationship toward practical applications of COF materials. PMID- 29584422 TI - Development of Certified Matrix-Based Reference Material as a Calibrator for Genetically Modified Rice G6H1 Analysis. AB - The accurate monitoring and quantification of genetically modified organisms (GMOs) are key points for the implementation of labeling regulations, and a certified reference material (CRM) acts as the scaleplate for quantifying the GM contents of foods/feeds and evaluating a GMO analytical method or equipment. Herein we developed a series of CRMs for transgenic rice event G6H1, which possesses insect-resistant and herbicide-tolerant traits. Three G6H1 CRMs were produced by mixing seed powders obtained from homozygous G6H1 and its recipient cultivar Xiushui 110 at mass ratios of 49.825%, 9.967%, and 4.986%. The between bottle homogeneity and within-bottle homogeneity were thoroughly evaluated with consistent results. The potential DNA degradation in transportation and shelf life were evaluated with an expiration period of at least 12 months. The property values of three CRMs (G6H1a, G6H1b, G6H1c) were given as (49.825 +/- 0.448) g/kg, (9.967 +/- 1.757) g/kg, and (4.986 +/- 1.274 g/kg based on mass fraction ratio, respectively. Furthermore, the three CRMs were characterized with values of (5.01 +/- 0.08)%, (1.06 +/- 0.22)%, and (0.53 +/- 0.11)% based on the copy number ratio using the droplet digital PCR method. All results confirmed that the produced G6H1 matrix-based CRMs are of high quality with precise characterization values and can be used as calibrators in GM rice G6H1 inspection and monitoring and in evaluating new analytical methods or devices targeting the G6H1 event. PMID- 29584423 TI - Ambient Nonmethane Hydrocarbon Levels Along Colorado's Northern Front Range: Acute and Chronic Health Risks. AB - Oil and gas (O&G) facilities emit air pollutants that are potentially a major health risk for nearby populations. We characterized prenatal through adult health risks for acute (1 h) and chronic (30 year) residential inhalation exposure scenarios to nonmethane hydrocarbons (NMHCs) for these populations. We used ambient air sample results to estimate and compare risks for four residential scenarios. We found that air pollutant concentrations increased with proximity to an O&G facility, as did health risks. Acute hazard indices for neurological (18), hematological (15), and developmental (15) health effects indicate that populations living within 152 m of an O&G facility could experience these health effects from inhalation exposures to benzene and alkanes. Lifetime excess cancer risks exceeded 1 in a million for all scenarios. The cancer risk estimate of 8.3 per 10 000 for populations living within 152 m of an O&G facility exceeded the United States Environmental Protection Agency's 1 in 10 000 upper threshold. These findings indicate that state and federal regulatory policies may not be protective of health for populations residing near O&G facilities. Health risk assessment results can be used for informing policies and studies aimed at reducing and understanding health effects associated with air pollutants emitted from O&G facilities. PMID- 29584424 TI - Controlling the Recognition and Reactivity of Alkyl Ammonium Guests Using an Anion Coordination-Based Tetrahedral Cage. AB - Caged structures have found wide application in a variety of areas, including guest encapsulation and catalysis. Although metal-based cages have dominated the field, anion-coordination-based cages are emerging as a new type of supramolecular ensemble with interesting host-guest properties. In the current work, we report a C3-symmetric tris-bis(urea) ligand based on the 2,4,6-triphenyl 1,3,5-triazine spacer, which assembles with phosphate anions to form an A4L4-type (A = anion, L = ligand) tetrahedral cage, 3, with unusually high packing coefficients (up to 99.5% for the best substrate). Cage 3 is able to adjust its size and shape (from 136 to 216 A3) by bending of the triphenyltriazine plane. This allows it to accommodate relatively large guests. In the case of DABCO, inclusion within the cage allows the degree of methylation to be controlled and the monomethylated product to be isolated cleanly under conditions where mixtures of the mono- and dimethylated adduct are obtained in the absence of cage 3. PMID- 29584425 TI - Leucine Promotes the Growth of Fetal Pigs by Increasing Protein Synthesis through the mTOR Signaling Pathway in Longissimus Dorsi Muscle at Late Gestation. AB - Leucine (Leu) plays an important role in protein synthesis and metabolism. The present study tested whether Leu supplementation in the diet for sows during late pregnancy could improve piglet birth weight, and it also investigated the possible underlying mechanism. Two hundred sows at day 70 of pregnancy were selected and assigned to four groups fed with following four diets until farrowing, respectively: corn and soybean meal-based diet group (CON), CON + 0.40% Leu, CON + 0.80% Leu, and CON + 1.20% Leu. We found that supplementing with 0.80% Leu significantly increased mean piglet birth weight ( P < 0.05). Supplementation with 0.40, 0.80, and 1.20% Leu increased the plasma concentration of Leu, while decreasing the plasma concentrations of valine (Val) and isoleucine (Ile) in both farrowing sows and newborn piglets ( P < 0.05). The protein expressions of amino acid transporters (including LAT1, SNAT1, SNAT2, 4F2hc, and rBAT) in duodenum, jejunum, ileum, longissimus dorsi muscle of newborn piglets, and placenta of sows showed a difference among the CON group and Leu supplemented groups. Expressions of p-mTOR, p-4E-BP1, and p-S6K1 in longissimus dorsi muscle were also enhanced in each of the supplemental Leu groups compared to CON ( P < 0.05). Collectively, these results indicated that 0.40-0.80% Leu supplementation during late gestation enhanced birth weight of fetal pigs by increasing protein synthesis through modulation of the plasma amino acids profile, amino acid transporters expression, and mTOR signaling pathway.

PMID- 29584426 TI - miRNA and mRNA Expression Profiles Reveal Insight into Chitosan-Mediated Regulation of Plant Growth. AB - Chitosan has been numerously studied as a plant growth regulator and stress tolerance inducer. To investigate the roles of chitosan as bioregulator on plant and unravel its possible metabolic responses mechanisms, we simultaneously investigated mRNAs and microRNAs (miRNAs) expression profiles of wheat seedlings in response to chitosan heptamer. We found 400 chitosan-responsive differentially expressed genes, including 268 up-regulated and 132 down-regulated mRNAs, many of which were related to photosynthesis, primary carbon and nitrogen metabolism, defense responses, and transcription factors. Moreover, miRNAs also participate in chitosan-mediated regulation on plant growth. We identified 87 known and 21 novel miRNAs, among which 56 miRNAs were induced or repressed by chitosan heptamer, such as miRNA156, miRNA159a, miRNA164, miRNA171a, miRNA319, and miRNA1127. The integrative analysis of miRNA and mRNA expression profiles in this case provides fundamental information for further investigation of regulation mechanisms of chitosan on plant growth and will facilitate its application in agriculture.

AB - Bacillus thuringiensis (Bt) can produce Cry proteins during the sporulation phase, and Cry protein is effective against lepidopteran, coleopteran, and dipteran insects and nematodes. However, Cry protein tends to be discharged into soil and nontarget plants through rainwater runoff, leading to reduced effective period toward target insects. In the present study, nano-Mg(OH)2 (magnesium hydroxide nanoparticles, MHNPs) were synthesized to control the loss of Cry1Ac protein and deliver protein to Helicoverpa armigera (Lepidoptera: Noctuidae). The results showed that Cry1Ac protein could be loaded onto MHNPs through electrostatic adsorption, and both MHNPs and Cry protein were stable during the adsorption process. Meanwhile, the Cry1Ac-loaded MHNPs could remain on the surface of cotton leaves, resulting in enhanced adhesion of Cry1Ac protein by 59.50% and increased pest mortality by 75.00%. Additionally, MHNPs could be slowly decomposed by acid medium and MHNPs showed no obvious influence on cotton, Bt, Escherichia coli, and H. armigera. Therefore, MHNPs could serve as an efficient nanocarrier for delivery of Cry1Ac protein and be used as a potential adjuvant for biopesticide in agricultural applications. PMID- 29584429 TI - Qualitative Study on the Production of the Allelochemicals Benzoxazinones by Inducing Polyploidy in Gramineae with Colchicine. AB - The possibility of inducing polyploidy in grasses by treatment with colchicine and its effect on the production and root exudate content of 2,4-dihydroxy-7 methoxy-2 H-1,4-benzoxazin-3-one (DIMBOA) and 2,4-dihydroxy-2 H-benzoxazin-3-one (DIBOA) was studied in wheat, corn, and rye. Caryopses treated with colchicine at concentrations in the range of 0.1-10 mg/mL for 8 and 48 h and with inoculation of the growth medium are markedly affected in terms of both the distribution and concentration levels of allelochemicals in plants. A greater accumulation was observed in the root with respect to the stem, and this increased with an increasing concentration of colchicine and with treatment time. Analysis of the compounds released by root exudates showed that treatment with colchicine at a concentration higher than 1 mg/mL caused a significant increase in the concentrations of allelochemicals measured in the growth medium. It is proposed that treatment with colchicine of seedling caryopses mixoploids plant populations and that the overall effect is an increase in the levels of allelochemicals released. The ecological implications of this behavior are discussed along with the impact of plant-plant interactions (allelopathy). PMID- 29584430 TI - Bicyclic Helical Peptides as Dual Inhibitors Selective for Bcl2A1 and Mcl-1 Proteins. AB - A 26-residue peptide BimBH3 binds indiscriminately to multiple oncogenic Bcl2 proteins that regulate apoptosis of cancer cells. Specific inhibition of the BimBH3-Bcl2A1 protein-protein interaction was obtained in vitro and in cancer cells by shortening the peptide to 14 residues, inserting two cyclization constraints to stabilize a water-stable alpha-helix, and incorporating an N terminal acrylamide electrophile for selective covalent bonding to Bcl2A1. Mass spectrometry of trypsin-digested bands on electrophoresis gels established covalent bonding of an electrophilic helix to just one of the three cysteines in Bcl2A1, the one (Cys55) at the BimBH3-Bcl2A1 protein-protein interaction interface. Optimizing the helix-inducing constraints and the sequence subsequently enabled electrophile removal without loss of inhibitor potency. The bicyclic helical peptides were potent, cell permeable, plasma-stable, dual inhibitors of Bcl2A1 and Mcl-1 with high selectivity over other Bcl2 proteins. One bicyclic peptide was shown to inhibit the interaction between a pro-apoptotic protein (Bim) and either endogenous Bcl2A1 or Mcl-1, to induce apoptosis of SKMel28 human melanoma cells, and to sensitize them for enhanced cell death by the anticancer drug etoposide. These approaches look promising for chemically silencing intracellular proteins. PMID- 29584431 TI - Structure Evolution and Drying Dynamics in Sliding Cholesteric Cellulose Nanocrystals. AB - The study of colloidal liquid crystals (LCs) reveals fundamental insights into the nature of ordered materials, giving rise to emergent properties with fascinating applications in soft matter nanotechnology. Here we investigate the shape instabilities, layer undulations, dynamic assembly, and collective behaviors in evaporating a cellulose nanocrystal-based cholesteric LC drop. During the drying process, the drop edges are pinned to the substrate with spontaneous convective flow occurring along the drop, which leads to nonequilibrium sliding of the individual cholesteric fragment with active ordering as well as hydrodynamic fluctuations and flow transitions in the bulk cholesteric phase. PMID- 29584432 TI - Quantum Mechanics Study on Hydrophilic and Hydrophobic Interactions in the Trivaline-Water System. AB - With the aim to elucidate hydrophobic effects in the unfolded state of peptides, DFT-M062X computations on the Val3H+. nH2O ( n up to 22) clusters have been accomplished. As far as the main chain is concerned, four conformers with beta strand and/or polyproline type II conformations, PPII (indicated as beta-beta, beta-PPII, PPII-beta, and PPII-PPII), have been found by changing the phi and psi angles. For bare peptide, the side chain (isopropyl) of each residue can independently take on three different orientations with negligible effects on energetics. The great isopropyl spatial separations in beta-beta and beta-PPII conformers allow for the construction of synergic and extensive water-water and water-peptide H-bonding in the minimal hydration Val3H+.22H2O models without significant steric encumbrance. Conversely, due to the proximity of the isopropyl of the central residue with the other two, some restrictions in the water shell construction around the peptide become evident for the PPII-PPII conformer and the number of energetically accessible structures decreases. This is indicative of correlated motion involving isopropyls and backbone mediated by water molecules, the origin of the nearest neighbor effects. Comparing the thermodynamic data of Ala3H+.22H2O and Val3H+.22H2O, what emerges is that both hydration enthalpy and entropy drive the beta-strand stability of the latter. PMID- 29584433 TI - Online Optimization of Total Acceptance in Hamiltonian Replica Exchange Simulations. AB - Replica exchange is a widely used sampling strategy in molecular simulation. While a variety of methods exist to optimize parameters for temperature replica exchange, less is known about how to optimize parameters for more general Hamiltonian replica exchange simulations. We present an algorithm for the online optimization of total acceptance for both temperature and Hamiltonian replica exchange simulations using stochastic gradient descent. We optimize the total acceptance, a heuristic objective function capturing the efficiency of replica exchange. Our approach is general and has several desirable properties, including: (1) it makes few assumptions about the system of interest, (2) optimization occurs online without the requirement of presimulation, and (3) most importantly, it readily generalizes to systems where there are multiple control parameters (e.g., temperatures, force constants, etc.) that determine the Hamiltonian of each replica. We explore some general properties of the algorithm on a simple harmonic oscillator system, and demonstrate its effectiveness on a more complex data-guided protein folding simulation.

AB - A boryl radical-triggered C-H functionalization of aliphatic ethers/amines or DMF with isocyanides is developed to deliver diverse phenanthridine derivatives in good to excellent yields. The substrate scope is broad, and a wide range of functional groups are tolerated under the standard conditions. The rapid removal of HBPin species by 4-cyanopyridine 1-oxide provides the driving force for this reaction. This new method should make boryl radicals widely applicable in organic synthesis. PMID- 29584435 TI - Thermochemistry, Tautomerism, and Thermal Decomposition of 1,5-Diaminotetrazole: A High-Level ab Initio Study. AB - Thermochemistry, kinetics, and mechanism of thermal decomposition of 1,5 diaminotetrazole (DAT), a widely used "building block" of nitrogen-rich energetic compounds, were studied theoretically at a high and reliable level of theory (viz., using the explicitly correlated CCSD(T)-F12/aug-cc-pVTZ procedure). Quantum chemical calculations provided detailed insight into the thermolysis mechanism of DAT missing in the existing literature. Moreover, several contradictory assumptions on the mechanism and key intermediates of thermolysis were resolved. The unimolecular primary decomposition reactions of the seven isomers of DAT were studied in the gas phase and in the melt using a simplified model of the latter. The two-step reaction of N2 elimination from the diamino tautomer was found to be the primary decomposition process of DAT in the gas phase and melt. The effective Arrhenius parameters of this process were calculated to be E a = 43.4 kcal mol-1 and log( A/s-1) = 15.2 in a good agreement with the experimental values. Contrary to the existing literature data, all other decomposition channels of DAT isomers turned out to be kinetically unimportant. Apart from this, a new primary decomposition channel yielding N2, cyanamide, and 1,1-diazene was found for some H-bonded dimers of DAT. We also determined a reliable and mutually consistent set of thermochemical values for DAT (Delta f H solid0 = 74.5 +/- 1.5 kcal.mol-1) by combining theoretically calculated (W1 multilevel procedure along with an isodesmic reaction) gas phase enthalpy of formation (Delta f H gas0 = 100.7 +/- 1.0 kcal.mol-1) and experimentally measured sublimation enthalpy (Delta sub H0 = 26.2 +/- 0.5 kcal.mol-1). PMID- 29584436 TI - Can Storage Time Improve the Physical Stability of Amorphous Pharmaceuticals with Tautomerization Ability Exposed to Compression? The Case of a Chloramphenicol Drug. AB - In this article we thoroughly investigated the physical stability of the amorphous form of a chloramphenicol drug. The tendency toward recrystallization of this drug has been examined (i) at nonisothermal conditions by means of a DSC technique; (ii) at isothermal conditions and temperature close to Troom by means of dielectric spectroscopy; (iii) at isothermal conditions and elevated temperatures of T = 323 K and 338 K by dielectric spectroscopy; and (iv) at conditions imitating the manufacturing procedure (i.e., elevated temperature and compression procedure). Our investigations have shown that amorphous chloramphenicol, stored at both standard storage and elevated temperature conditions, does not reveal a tendency toward recrystallization. However, compression significantly changes this behavior and destabilizes the examined compound. We found that due to chemical equilibration of the sample, the elongation of the storage time before compression might improve the physical stability of the examined pharmaceutical exposed to compression 34-times. PMID- 29584437 TI - High Photoinduced Ordering and Controllable Photostability of Hydrophilic Azobenzene Material Based on Relative Humidity. AB - Azobenzene materials provide an effective way for liquid crystal (LC) alignment besides traditional rubbing technology. A strong relationship between relative humidity (RH) and the photoalignment quality of hydrophilic azobenzene dye brilliant yellow (BY) has been investigated. Good photoalignment quality can only be ensured at about 40% RH or below. On the other hand, the photostability of the alignment layer is also influenced dramatically by RH. The rewritability can be guaranteed at extremely low RH (<=10%). It is gradually lost with increasing RH, and the alignment layer becomes photostable against further light exposure when at 40% RH or above. Therefore, the BY photoalignment layer can be tuned from rewritable to photostable by simply adjusting RH, and thus multistep photopatterned alignments can be obtained and reserved based on this method. Similar properties are also expected for other hydrophilic azobenzene photoalignment materials, where the specific RH values may vary correspondingly. The reason is due to the strong intermolecular interaction and J-aggregate formation of BY molecules with water insertion. Moreover, the lyotropic LC formed by J-aggregated BY molecules in aqueous solution is reported here.

The nomenclature employed and the accompanying characterization data are often unclear and incomplete, leading to a situation in which apparently the same form has been reported by different authors or claimed by different inventors. A comprehensive solid forms screen and a full and careful comparison with the literature data has been performed to draw a reliable picture of the solid forms landscape of APX.

This unusual natural product possesses a highly modified tryptophan derived indole fragment fused to an alpha-methylserine-derived oxazoline ring, and a unique noncanonical amino acid residue named tambroline (11). A convergent synthesis of tambromycin was achieved by a 13-step route that leveraged recent developments in the field of C-H functionalization to prepare the complex indole fragment, as well as an efficient synthesis of tambroline that featured a diastereoselective amination of homoproline. PMID- 29584442 TI - Drainage from a Fluid-Handling Component with Multiple Orifices due to Inclination or Rotation. AB - The onset of drainage of liquids from fluid-handling components with two or more orifices was evaluated. The components were filled with water, ethylene glycol, or ethyl alcohol and oriented vertically with their orifices facing downward. The lower end of the components was slowly raised toward the horizon. No flow occurred until a critical angle of inclination was reached. The resistance to drainage was greatest for small, closely spaced orifices and declined precipitously as the size and spacing of the orifices increased. The onset of drainage was successfully modeled as a balance between the hydrostatic pressure in the bulk liquid and the Laplace pressure of the air-liquid interfaces present within the orifices. PMID- 29584443 TI - Distribution Control-Oriented Intercalation of a Cationic Metal Complex into Layered Silicates Modified with Organosulfonic-Acid Moieties. AB - A layered sodium silicate, octosilicate (Na2Si8O17. nH2O), was modified with an organosulfonic-acid moiety (sulfonated propyl (SPr) group, sulfonated phenethyl (SPhE) group, or sulfonated p-trifluoromethylphenyl (STFPh) group) for use as a host material to accommodate a cationic guest, tris(2,2'-bipyridine)ruthenium(II) cation ([Ru(bpy)3]2+). The organosulfonic-acid moiety was bound to the silicate layer via a reaction of an alkylammonium-exchanged octosilicate with a silane coupling agent, and subsequent treatment (oxidation or sulfonation) of the bound organosilyl groups; the surface densities of the organosulfonic-acid moiety were varied by controlling the added amount of silane coupling agents. Adsorption of [Ru(bpy)3]2+ onto surface-modified octosilicates was conducted to find that some surface-modified octosilicates successfully adsorbed [Ru(bpy)3]2+ in the interlayer space (intercalation), while other surface-modified octosiliates did not. In addition, the UV-vis absorption and the luminescence indicate that intercalated [Ru(bpy)3]2+ diffused in the interlayer and that the distribution of the time-averaged location varied depending on the kind and amount of the organosulfonic-acid moieties. Thus, the kind and surface density of the organosulfonic-acid moiety, which correlates to the interactions between the group and the guest species, the volume of free nanospace for adsorption and motion of guests, and the swelling properties, are the key factors not only for the intercalation ability but also for the dynamics of the guest in the interlayer space. PMID- 29584444 TI - Kinetics of Surface-Mediated Fibrillization of Amyloid-beta (12-28) Peptides. AB - Surfaces or interfaces are considered to be key factors in facilitating the formation of amyloid fibrils under physiological conditions. In this report, we study the kinetics of the surface-mediated fibrillization (SMF) of an amyloid beta fragment (Abeta12-28) on mica. We employ a spin-coating-based drying procedure to control the exposure time of the substrate to a low-concentration peptide solution and then monitor the fibril growth as a function of time via atomic force microscopy (AFM). The evolution of surface-mediated fibril growth is quantitatively characterized in terms of the length histogram of imaged fibrils and their surface concentration. A two-dimensional (2D) kinetic model is proposed to numerically simulate the length evolution of surface-mediated fibrils by assuming a diffusion-limited aggregation (DLA) process along with size-dependent rate constants. We find that both monomer and fibril diffusion on the surface are required to obtain length histograms as a function of time that resemble those observed in experiments. The best-fit simulated data can accurately describe the key features of experimental length histograms and suggests that the mobility of loosely bound amyloid species is crucial in regulating the kinetics of SMF. We determine that the mobility exponent for the size dependence of the DLA rate constants is alpha = 0.55 +/- 0.05, which suggests that the diffusion of loosely bound surface fibrils roughly depends on the inverse of the square root of their size. These studies elucidate the influence of deposition rate and surface diffusion on the formation of amyloid fibrils through SMF. The method used here can be broadly adopted to study the diffusion and aggregation of peptides or proteins on various surfaces to investigate the role of chemical interactions in two-dimensional fibril formation and diffusion. PMID- 29584445 TI - Protectin DX attenuates LPS-induced inflammation and insulin resistance in adipocytes via AMPK-mediated suppression of the NF-kappaB pathway. AB - Several studies have demonstrated that protectins, omega-3 fatty acid-derived proresolution mediators, may ameliorate inflammation. Recently, protectin DX (PDX) was also reported to attenuate inflammation and insulin resistance in several cell types. However, the effects of PDX on inflammation in adipocytes remain ambiguous. In this study, we found that PDX treatment suppressed adipogenesis and lipid accumulation during 3T3-L1 differentiation. Treatment of differentiated 3T3-L1 cells with PDX stimulated AMP-activated protein kinase (AMPK) phosphorylation in a dose-dependent manner. PDX-induced AMPK phosphorylation blocked lipopolysaccharide (LPS)-induced secretion of proinflammatory cytokines, such as tumor necrosis factor-alpha and monocyte chemoattractant protein-1. Treatment of 3T3-L1 cells with PDX alleviated LPS induced NF-kappaB and inhibitory factor kappaB phosphorylation. Furthermore, PDX treatment diminished LPS-induced impairment of insulin signaling and insulin stimulated glucose uptake, as well as fatty acid oxidation. These effects were decreased by silencing AMPK expression with small-interfering RNA. In conclusion, the current findings suggest that PDX attenuates inflammation and insulin resistance in adipocytes via an AMPK-dependent pathway, which in turn provides evidence that PDX has anti-inflammatory and antidiabetic effects in adipocytes. PMID- 29584446 TI - The insulin receptor is expressed and functional in cultured blood-brain barrier endothelial cells but does not mediate insulin entry from blood to brain. AB - Insulin and its receptor are known to be present and functional in the brain. Insulin cerebrospinal fluid concentrations have been shown to correlate with plasma levels of insulin in a nonlinear fashion, indicative of a saturable transport pathway from the blood to the brain interstitial fluid. The aim of the present study was to investigate whether insulin was transported across brain endothelial cells in vitro via an insulin receptor-dependent pathway. The study showed that the insulin receptor was expressed at both the mRNA and protein levels in bovine brain endothelial cells. Luminally applied radiolabeled insulin showed insulin receptor-mediated binding to the endothelial cells. This caused a dose-dependent increase in Akt-phosphorylation, which was inhibited by coapplication of an insulin receptor inhibitor, s961, demonstrating activation of insulin receptor signaling pathways. Transport of insulin across the blood-brain barrier in vitro was low and comparable to that of a similarly sized paracellular marker. Furthermore, insulin transport was not inhibited by coapplication of an excess of unlabeled insulin or an insulin receptor inhibitor. The insulin transport and uptake studies were repeated in mouse brain endothelial cells demonstrating similar results. Although it cannot be ruled out that culture induced changes in the cell model could have impaired a potential insulin transport mechanism, these in vitro data indicate that peripheral insulin must reach the brain parenchyma through alternative pathways rather than crossing the blood-brain barrier via receptor mediated transcytosis.

AB - The popularity of preprocessed fresh fishery products such as fillets and peeled shrimps is growing in today s market due to their convenience for subsequent processing and cooking. However, fishery products are highly perishable because of the combined actions of biochemical reactions and microbial metabolism. Various methods have been proposed to address this problem. Among these methods, bio-based edible coating has been highlighted as a promising solution. This review updates and summarizes the recent literature on the application of coatings for the preservation of fishery products including the aspects of coating carriers, composite natural preservatives and coating methods, and a discussion of the protective effects based on microbial, physicochemical and sensorial evaluations. Moreover, some challenges and future research directions regarding optimization of formulas and exploration of mechanisms of coating are also discussed. Given consumer demand for fresh fishery products with long shelf life, edible coatings that are environmentally friendly and effective alternative will be used to extend the shelf life of fishery products. PMID- 29584449 TI - Efficacy of synbiotic supplementation in patients with nonalcoholic fatty liver disease: A systematic review and meta-analysis of clinical trials: Synbiotic supplementation and NAFLD. AB - OBJECTIVE: We systematically reviewed available randomized clinical trials (RCTs) to elucidate the overall effects of synbiotic supplementation in patients with nonalcoholic fatty liver disease (NAFLD). METHODS: PubMed, Scopus, ISI Web of science and Google Scholar were searched up to December, 2017. All RCTs using synbiotic supplements to treat NAFLD included in this systematic review and meta analysis. Mean Difference (MD) was pooled using a random-effects model. RESULTS: Eleven eligible databases from seven RCTs were identified for the present meta analysis. Our results showed that synbiotic supplementation can decrease body weight, fasting blood sugar, insulin, low density lipoprotein cholesterol, total cholesterol, triglyceride, high-sensitivity C-reactive protein, tumor necrosis factor alpha, alanine transaminase and aspartate transaminase levels among patients with NAFLD. In contrast, synbiotic did not have favorable effects on body mass index (BMI), waist circumference, homeostasis model assessment for insulin resistance (HOMA-IR), and high density lipoprotein cholesterol (HDL) levels compared with the placebo group. CONCLUSION: The current study revealed that synbiotic supplementation has favorable effect on inflammatory factors, liver enzymes and some anthropometric indices, lipid profiles and glucose homeostasis parameters in patients with NAFLD. PMID- 29584447 TI - Inspiratory Muscle Rehabilitation in Critically Ill Adults. A Systematic Review and Meta-Analysis. AB - RATIONALE: Respiratory muscle weakness is common in critically ill patients; the role of targeted inspiratory muscle training (IMT) in intensive care unit rehabilitation strategies remains poorly defined. OBJECTIVES: The primary objective of the present study was to describe the range and tolerability of published methods for IMT. The secondary objectives were to determine whether IMT improves respiratory muscle strength and clinical outcomes in critically ill patients. METHODS: We conducted a systematic review to identify randomized and nonrandomized studies of physical rehabilitation interventions intended to strengthen the respiratory muscles in critically ill adults. We searched the MEDLINE, Embase, HealthSTAR, CINAHL, and CENTRAL databases (inception to September Week 3, 2017) and conference proceedings (2012 to 2017). Data were independently extracted by two authors and collected on a standardized report form. RESULTS: A total of 28 studies (N = 1,185 patients) were included. IMT was initiated during early mechanical ventilation (8 studies), after patients proved difficult to wean (14 studies), or after extubation (3 studies), and 3 other studies did not report exact timing. Threshold loading was the most common technique; 13 studies employed strength training regimens, 11 studies employed endurance training regimens, and 4 could not be classified. IMT was feasible, and there were few adverse events during IMT sessions (nine studies; median, 0%; interquartile range, 0-0%). In randomized trials (n = 20), IMT improved maximal inspiratory pressure compared with control (15 trials; mean increase, 6 cm H2O; 95% confidence interval [CI], 5-8 cm H2O; pooled relative ratio of means, 1.19; 95% CI, 1.14-1.25) and maximal expiratory pressure (4 trials; mean increase, 9 cm H2O; 95% CI, 5-14 cm H2O). IMT was associated with a shorter duration of ventilation (nine trials; mean difference, 4.1 d; 95% CI, 0.8-7.4 d) and a shorter duration of weaning (eight trials; mean difference, 2.3 d; 95% CI, 0.7 4.0 d), but confidence in these pooled estimates was low owing to methodological limitations, including substantial statistical and methodological heterogeneity. CONCLUSIONS: Most studies of IMT in critically ill patients have employed inspiratory threshold loading. IMT is feasible and well tolerated in critically ill patients and improves both inspiratory and expiratory muscle strength. The impact of IMT on clinical outcomes requires future confirmation.

AB - BACKGROUND: Clinical-community collaboration is a promising strategy for pediatric obesity treatment, but current research is limited. This study examined the effect of a family-based treatment program embedded in a primary care clinic on retention and changes in child weight status at 1 year. METHODS: Children (2 16 years, BMI >=85th percentile, 87.0% Hispanic) and their parents were recruited from a single pediatric clinic for Healthy Hawks Primary Plus (HHP+). Children were referred by physicians and enrolled by a bilingual clinic-based recruitment coordinator. Participants received 12 weekly 2-hour sessions focused on lifestyle modification and health behavior change and then received bimonthly follow-up visits with their clinic-based physician through 1-year follow-up. Child body mass index (BMI) percentage of the 95th percentile (%BMIp95) was measured as the primary outcome at baseline, postintervention, and 1-year follow-up. Random effect multilevel models assessed changes in child weight status over time accounting for clustering by family. To further evaluate the impact, HHP+ retention and changes in child weight status were compared to a standard 12-week treatment program only. RESULTS: HHP+ participants had significantly better retention at 1 year (73.9%, p <= 0.001) compared to the standard treatment program (38.3%). In HHP+, physician visit attendance was significantly correlated with retention at 1 year (r = 0.69, p <= 0.001), and HHP+ completers had significant reductions in %BMIp95 between baseline and 1-year follow-up (p = 0.03). CONCLUSION: Clinical-community partnerships might be a promising strategy to improve retention and reduce child weight status in populations currently underrepresented in obesity treatment. PMID- 29584451 TI - Epithelial Heparan Sulfate Contributes to Alveolar Barrier Function and Is Shed during Lung Injury. AB - The lung epithelial glycocalyx is a carbohydrate-enriched layer lining the pulmonary epithelial surface. Although epithelial glycocalyx visualization has been reported, its composition and function remain unknown. Using immunofluorescence and mass spectrometry, we identified heparan sulfate (HS) and chondroitin sulfate within the lung epithelial glycocalyx. In vivo selective enzymatic degradation of epithelial HS, but not chondroitin sulfate, increased lung permeability. Using mass spectrometry and gel electrophoresis approaches to determine the fate of epithelial HS during lung injury, we detected shedding of 20 saccharide-long or greater HS into BAL fluid in intratracheal LPS-treated mice. Furthermore, airspace HS in clinical samples from patients with acute respiratory distress syndrome correlated with indices of alveolar permeability, reflecting the clinical relevance of these findings. The length of HS shed during intratracheal LPS-induced injury (>=20 saccharides) suggests cleavage of the proteoglycan anchoring HS to the epithelial surface, rather than cleavage of HS itself. We used pharmacologic and transgenic animal approaches to determine that matrix metalloproteinases partially mediate HS shedding during intratracheal LPS induced lung injury. Although there was a trend toward decreased alveolar permeability after treatment with the matrix metalloproteinase inhibitor, doxycycline, this did not reach statistical significance. These studies suggest that epithelial HS contributes to the lung epithelial barrier and its degradation is sufficient to increase lung permeability. The partial reduction of HS shedding achieved with doxycycline is not sufficient to rescue epithelial barrier function during intratracheal LPS-induced lung injury; however, whether complete attenuation of HS shedding is sufficient to rescue epithelial barrier function remains unknown. PMID- 29584454 TI - Novel App- and Web-Supported Diabetes Prevention Program to Promote Weight Reduction, Physical Activity, and a Healthier Lifestyle: Observation of the Clinical Application. AB - BACKGROUND: The increasing incidence of type 2 diabetes mellitus presents as a tsunami of health problems and health care costs. Preventing this development needs to target the underlying rise in metabolic syndrome cases through obesity and unhealthy lifestyle. Obesity is frequently perceived as a social issue with implicit psychological strain; health apps/weight-reduction programs are mushrooming from this side. The present program intends to bring weight reduction into the hands of HCPs by utilizing advanced digital technology. METHODS: The prospective observational study analyzed 166 patients with metabolic syndrome as treated for weight reduction in 23 medical practices in Germany. Two approaches were observed: usual care (UC; n = 57) and a personalized health management program (PHM; n = 109). Key for PHM was the interaction between HCP and patient: reinforcing lifestyle changes through personalized goals and HCP-feedback via app and web-based communication. Comparing PHM/UC was based on a time-to-success (5% weight reduction) analysis by Cox regression. Further exploratory analyses addressed the comparison of achievers and nonachievers. RESULTS: Cox regression adjusted for sex, age, and BMI revealed a chance ratio for weight reduction of 6.2 (2.4-16.2, p = .0003) favoring PHM. Expected success rates were 44.8% for PHM, 11.5% for UC. PHM achievers reduced their weight by 8.0% and lowered their BMI by 2.7 points. Motivation for lifestyle changes represented a key for success. CONCLUSIONS: The approach of enhanced interaction of HCPs and patients via app- and web-based communication was a clear success and delivered favorable responder rates. Treating obesity from a medical viewpoint will help to deepen the motivation for changing lifestyles. The study represents a cornerstone for a wider scoped application of these novel digital health approaches.

AB - OBJECTIVE: To determine the proportion of non-concussed, neurologically normal children with failures on a vestibular and oculomotor examination for concussion performed in an acute setting. DESIGN: This was a cross-sectional study of subjects 6-18 years old presenting to a paediatric emergency department with non neurologic chief complaints. The examination was administered by a paediatric emergency medicine physician, and includes assessments of dysmetria, nystagmus, smooth pursuits, saccades, gaze stability, near-point of convergence, and gait/balance testing. RESULTS: Of the 295 subjects enrolled, 24% failed at least one element of testing. About 13% had >1 failed element and 5% had >2 failed elements. About 29% of females and 19% of males had failed examinations. By age, 15% of subjects 6-8 years old, 32% 9-11 years, 32% 12-14 years, and 26% 15-18 years had failed examinations. Overall, 10% were unable to complete the exam due to developmental age. CONCLUSIONS: The provider should be aware that a proportion of non-concussed children may demonstrate failure on a single element of the vestibular and oculomotor exam. While this testing is of benefit to the acute care provider in diagnosing paediatric concussion, its utility is greatest in the context of an injury history with acute onset of concussion symptoms. PMID- 29584453 TI - Rural Residence and COPD Exacerbations: Analysis of the SPIROMICS Cohort. AB - RATIONALE: Rural residence is associated with poor outcomes in several chronic diseases. The association between rural residence and chronic obstructive pulmonary disease (COPD) exacerbations remains unclear. OBJECTIVE: To determine the independent association between rural residence and COPD-related outcomes including COPD exacerbations, airflow obstruction and symptom burden. METHODS: A total of 1684 Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) participants with FEV1/FVC<0.70 had geocoding-defined rural-urban residence status determined (N=204 rural and N=1480 urban). Univariate and multivariate logistic and negative binomial regressions were performed to assess the independent association between rurality and COPD outcomes including exacerbations, lung function, and symptom burden. The primary exposure of interest was rural residence, determined by geocoding of home address to the block level at time of study enrollment. Additional covariates of interest included demographic and clinical characteristics, occupation, and occupational exposures.The primary outcome measures were exacerbations determined over the one year course after enrollment by quarterly telephone calls and at an annual research clinic visit. Odds ratio and incidence rate of exacerbations that required treatment with medications including steroids or antibiotics (total exacerbations), and exacerbations leading to hospitalization (severe exacerbations) were determined after adjusting for relevant covariates. RESULTS: Rural residence was independently associated with 70% increase in odds of total exacerbations [OR 1.70 (95% CI 1.13-2.56); p=0.012] and 46% higher incidence rate of total exacerbations [IRR 1.46 (95% CI 1.02-2.10); p=0.039]. There was no association between rural residence and severe exacerbations. Agricultural occupation was independently associated with increased odds and incidence of total and severe exacerbations. Inclusion of agricultural occupation to analysis attenuated the association between rural residence and odds and incidence rate of total exacerbations [OR 1.52 (95% CI 1.00-2.32; p=0.05) and IRR 1.39 (95% CI 0.97 - 1.99); p=0.07]. There was no difference in symptoms or airflow obstruction between rural and urban participants. CONCLUSIONS: Rural residence is independently associated with increased odds and incidence of total, but not severe COPD exacerbations. These associations are not fully explained by agriculture-related exposures, highlighting the need for future research into potential mechanisms of increased risk of COPD exacerbations in the rural population.

AB - Avelumab is a human anti-PD-L1 checkpoint inhibitor with clinical activity in multiple solid tumors. Here, we describe the rationale and design for JAVELIN Ovarian 200 (NCT02580058), the first randomized Phase III trial to evaluate the role of checkpoint inhibition in women with ovarian cancer. This three-arm trial is comparing avelumab administered alone or in combination with pegylated liposomal doxorubicin versus pegylated liposomal doxorubicin alone in patients with platinum-resistant/refractory recurrent ovarian, fallopian tube or peritoneal cancer. Eligible patients are not preselected based on PD-L1 expression and may have received up to three prior lines of chemotherapy for platinum-sensitive disease, but none for resistant disease. Overall survival and progression-free survival are primary end points, and secondary end points include biomarker evaluations and pharmacokinetics. PMID- 29584457 TI - Acupoint Massage for Managing Cognitive Alterations in Older Adults: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Cognitive disorders pose a major problem in the aging population across the globe. Acupoint massage has been used to improve cognitive functions in older adults. In this study, the authors performed a meta-analysis to evaluate the usefulness of acupoint massage in preventing cognitive declines in older adults. DESIGN: The authors searched for randomized controlled trials (RCTs) reporting on the effectiveness of acupoint massage on cognition in older adults in the following literature databases: PubMed, MEDLINE, Embase, CINAHL, ScienceDirect, Foreign Medical Journal Service, Cochrane Library, VIP Information, Chinese National Knowledge Infrastructure, WANFANG, and Chinese Biomedical. Two reviewers independently extracted the data related to the study and participants' characteristics and the cognitive impairment outcomes. Only RCTs meeting the inclusion criteria were used in the present meta-analysis. RESULTS: Eight RCTs with 657 participants in total (age >=60 years) were included. It is actually 8 for synthetic and 6 in the meta-analysis. The authors calculated the pooled estimates of the random effects of changes in the Mini Mental State Examination to compare the groups with and without acupoint massage. The merged mean difference (MD) was 1.94 (95% confidence interval, C.I., [1.41 2.47], p < 0.00001) after 3 months of acupoint massage treatment and 3.04 (95% C.I. [2.43-3.64], p < 0.00001) after 6 months of treatment. They also calculated the merged MD of the Wechsler Memory Scale-Revised Chinese version after 6 months of acupoint massage. Visual Reproduction was 2.95 (95% C.I. [1.30-4.60], p = 0.0005), Associate Learning was 1.89 (95% C.I. [1.41-2.37], p < 0.00001), Logical Memory was 2.85 (95% C.I. [2.06-3.63], p < 0.00001), and Digit Span was 3.16 (95% C.I. [2.59-3.73], p < 0.00001). The Cochrane Handbook for Systematic Reviews of Interventions was used to rate the quality of the studies, which was moderate overall. CONCLUSION: The findings suggested that acupoint massage is an effective intervention for maintaining cognitive functions in older adults. PMID- 29584458 TI - The effect of an L/N-type calcium channel blocker on intradialytic blood pressure in intradialytic hypertensive patients. AB - BACKGROUND: Intradialytic hypertension (HTN), which is one of the poor prognostic markers in patients undergoing hemodialysis, may be associated with sympathetic overactivity. The L/N-type calcium channel blocker, cilnidipine, has been reported to suppress sympathetic nerves activity in vivo. Therefore, we hypothesized that cilnidipine could attenuate intradialytic systolic blood pressure (SBP) elevation. METHODS: Fifty-one patients on chronic hemodialysis who had intradialytic-HTN (SBP elevation >=10 mmHg during hemodialysis) and no fluid overload were prospectively randomized into two groups: control and cilnidipine groups. Cilnidipine group patients took cilnidipine (10 mg/day) for 12 weeks. The primary endpoint was the change in the intradialytic SBP elevation before and after the 12-week intervention. RESULTS: Before the intervention, no differences were observed in age, sex or pre-dialytic SBP (148.5 +/- 12.9 vs. 148.3 +/- 19.3 mmHg) between the two groups. Intradialytic SBP elevation was unchanged in the control group. Cilnidipine significantly lowered the post-dialytic SBP with an attenuation of the intradialytic SBP elevation from 12.0 +/- 15.4 mmHg to 4.8 +/- 10.1 mmHg. However, the observed difference in the intradialytic SBP elevation by cilnidipine did not reach statistical significance (group*time interaction effect p = 0.25). Cathecolamine levels were unaffected by the intervention in both groups. CONCLUSION: Cilnidipine lowers both the pre- and post-dialytic SBP and might attenuate intradialytic SBP elevation. Therefore, cilnidipine may be effective in lowering SBP during HD in patients with intradialytic-HTN. PMID- 29584459 TI - Perimenstrual asthma: Report of a case with therapeutic intervention of oral prednisone. AB - INTRODUCTION: Many asthmatic women of childbearing age experience cyclical aggravation of asthmatic symptoms during the perimenstrual period, or perimenstrual asthma (PMA). PMA is considered to be a difficult-to-treat asthma phenotype; conventional asthma therapies are not always effective against PMA. CASE STUDY: We report a case of a 27-year-old female with PMA who had received standard asthma treatment since 2013. RESULT: The patient showed a dramatic response to therapeutic intervention of oral prednisone, taken for 7 days prior to menstruation each month, in a dose-dependent manner. CONCLUSION: Premenstrual treatment with oral prednisone may be a successful new direction for the treatment of PMA, a troublesome type of asthma. PMID- 29584460 TI - Strengthening One Health Through Investments in Agricultural Preparedness. AB - There are links among agriculture and zoonotic diseases, transboundary diseases in domesticated and wild animals, climate patterns, and human population migrations. A natural or intentionally occurring high-consequence infectious disease ("biothreat") often has no geographic boundaries and has the potential to result in disease epidemics in humans, animals, or both. Although significant strides have been made globally in preparing for a natural or intentional introduction of an emerging and/or zoonotic disease, much remains to be accomplished. Enhancing animal health and well-being is a vital component to enable a sustainable, safe, and nutritious food supply for global food economies. This article explores the biothreat environment, its One Health interrelationship, and the significance and role of US agriculture in One Health. We provide an overview of the US Emergency Medical Countermeasure Enterprise (EMCE) and current state of veterinary and zoonotic medical countermeasures portfolio management in the US government, veterinary biologic industry, not-for profit groups, and public-private partnerships. The highest zoonotic and epizootic threats to the US livestock industry are briefly reviewed, and currently available veterinary medical countermeasures are presented. Lastly, important gaps and priorities are identified, followed by specific recommendations to address these gaps. PMID- 29584461 TI - Case Studies in Exercise and Sport Sciences: A Powerful Tool to Bridge the Science-Practice Gap. AB - Despite the progress made by the scientific exercise community in collaborating and communicating with non-scientist coaches, there is room for improvement. Coaches find research difficult to understand, feel that their interests are not being addressed by exercise research, and rely on peer-discussion to further their coaching knowledge base while consuming little peer-reviewed articles. One useful strategy to bridge the science-practice gap is with case-studies. In addition to furthering our understanding of the physiology, psychology, and training schedules of elite athletes, case studies can serve 1) as a useful communication channel with coaches if presented as narratives and 2) to establish and strengthen relationships between scientists and coaches leading to fruitful research collaborations. The purpose of this invited commentary is to discuss these two less-recognized benefits of case-studies, and propose a way to incorporate case-studies more frequently alongside group-based studies. PMID- 29584463 TI - Do we still need cryoprecipitate? Cryoprecipitate and fibrinogen concentrate as treatments for major hemorrhage - how do they compare? AB - INTRODUCTION: Major hemorrhage is a source of significant mortality and morbidity worldwide. Identification and characterization of coagulation impairment associated with major hemorrhage has suggested a key role for fibrinogen deficiency, however the optimum mode of replacement of fibrinogen remains unclear, and standardized major hemorrhage protocols may overlook context dependent variations in individual patients' clotting derangement. Areas covered: This paper examines the current practice and evidence regarding the role of different modes of fibrinogen replacement in major hemorrhage in 3 distinct clinical settings: trauma, obstetric hemorrhage, and gastrointestinal hemorrhage with associated liver disease. A literature search was carried out electronically using Athens access to the National Health Service evidence health information resources, primarily PubMed and Google Scholar. Expert commentary: Two key questions need to be addressed. First, what is the role of concentrated fibrinogen (by comparison to no fibrinogen), and second, which concentrated source or product is more effective (or cost-effective)? Current practice and concept is derived largely from small pilot trials in the trauma setting, but results from larger studies are awaited. More comparative data on changes to clotting profiles in different groups of bleeding patients are needed to help delineate differences and guide interventional treatment studies. PMID- 29584462 TI - Effects of Caffeinated Gum on a Battery of Soccer-Specific Tests in Trained University-Standard Male Soccer Players. AB - The purpose of this study was to determine whether caffeinated gum influenced performance in a battery of soccer-specific tests used in the assessment of performance in soccer players. In a double-blind, randomized, crossover design, 10 male university-standard soccer players (age: 19 +/- 1 years, stature: 1.80 +/ 0.10 m, body mass: 75.5 +/- 4.8 kg) masticated a caffeinated (200 mg; caffeine) or control (0 mg; placebo) gum on two separate occasions. After a standardized warm-up, gum was chewed for 5 min and subsequently expectorated 5 min before players performed a maximal countermovement jump, a 20-m sprint test, and the Yo Yo Intermittent Recovery Test Level 1. Performance on 20-m sprints was not different between trials (caffeine: 3.2 +/- 0.3 s, placebo: 3.1 +/- 0.3 s; p = .567; small effect size: d = 0.33), but caffeine did allow players to cover 2.0% more distance during Yo-Yo Intermittent Recovery Test Level 1 (caffeine: 1,754 +/ 156 m, placebo: 1,719 +/- 139 m; p = .016; small effect size: d = 0.24) and increase maximal countermovement jump height by 2.2% (caffeine: 47.1 +/- 3.4 cm, placebo: 46.1 +/- 3.2 cm; p = .008; small effect size: d = 0.30). Performance on selected physical tests (Yo-Yo Intermittent Recovery Test Level 1 and countermovement jump) was improved by the chewing of caffeinated gum in the immediate period before testing in university-standard soccer players, but the sizes of such effects were small. Such findings may have implications for the recommendations made to soccer players about to engage with subsequent exercise performance. PMID- 29584464 TI - Endophyte-enhanced phytoremediation of DDE-contaminated using Cucurbita pepo: A field trial. AB - Although the use of the pesticide 2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane (DDT) was banned from the mid-1970s, its most abundant and recalcitrant degradation product, 2,2-bis(p-chlorophenyl)-1,1-dichloro-ethylene (DDE), is still present in terrestrial and aquatic ecosystems worldwide. Zucchini (Cucurbita pepo ssp. pepo) has been shown to accumulate high concentrations of DDE and was proposed for phytoremediation of contaminated soils. We performed a field trial covering a full plant life cycle. C. pepo plants inoculated with the plant growth-promoting endophytic strains Sphingomonas taxi UH1, Methylobacterium radiotolerans UH1, Enterobacter aerogenes UH1, or a consortium combining these 3 strains were grown on a DDE-contaminated field for 100 days. The effects of these inoculations were examined at both the plant level, by evaluating plant weight and plant DDE-content, and at the level of the cultivable and total endophytic communities. Inoculating plants with S. taxi UH1, M. radiotolerans UH1, and the consortium increased plant weight. No significant effects of the inoculations were observed on DDE-concentrations in plant tissues. However, the amount of DDE accumulated by C. pepo plants per growing season was significantly higher for plants that were inoculated with the consortium of the 3 strains. Therefore, inoculation of C. pepo with DDE-degrading endophytes might be promising for phytoremediation applications. PMID- 29584465 TI - Electromagnetic field pretreatment of Sinapis alba seeds improved cadmium phytoextraction. AB - It was hypothesized that electromagnetic field (EMF) pretreatment of white mustard (Sinapis alba L.) seeds could increase the accumulation of non-essential, pollutant heavy metals such as cadmium (Cd) in shoots. Seeds of white mustard were treated with either 60 or 120 mT of alternating EMF (50 Hz) for 1 minute and then grown in a Petri dish in the presence of Cd, in comparison to the control (seeds grown without EMF pretreatment). Biomass production and content of calcium (Ca) and Cd in seedling shoots were measured. The Cd content in shoots from the EMF-treated seeds was higher in both variants than in the control (by 73% and 78%, respectively; p < 0.05). In plants treated with 60 mT, the Ca content was slightly, but significantly, lower (3%) than in the control. EMF stimulation did not affect the biomass production. The results have shown potential benefits of this physical seed pretreatment method in the context of cadmium phytoextraction, but more research is needed. PMID- 29584466 TI - Characterization of coal fly ash and use of plants growing in ash pond for phytoremediation of metals from contaminated agricultural land. AB - Mobilization of heavy metals around coal power plants due to improper disposal of fly ash (FA) and wastewater have led to release of pollutants into the environment. For protection of inimitable natural resources, application of economical and effective technologies is needed such as phytoremediation is cost effective, ecofriendly and a better option for elimination of metal from contaminated sites. Twelve plant species were sampled from ash dyke of Singrauli and screened for accumulation of metals for this study. Mobilization ratio of metals from soil to plant was evaluated to determine translocation factor. CILLAS analyzer, Raman spectroscopy and SEM-EDX were used for characterization of particle size, functional groups and morphology of fly ash. Results showed mean metal concentrations in contaminated soil for Fe, Mn, Cr, Zn, Ni, Cu, Cd and Pb were 909.4, 60.6, 9.5, 134.8, 13.6, 26.7, 2.9 and 25.4 ug g-1 respectively. Enrichment factors for soil, root and shoot for a contaminated site were 1.9, 3.8 & 4.3 for Zn and 2.7, 3.5 & 3.8 for Cd. Six hyper-accumulators with absorption efficiency >1 viz. I. carnea, S. nigrum, S. munja, T. angustifolia, C. dactylon and P. hysterophorus were identified which may be cultivated successively to reclaim and restore damaged agricultural land. PMID- 29584467 TI - Regression model, artificial neural network, and cost estimation for biosorption of Ni(II)-ions from aqueous solutions by Potamogeton pectinatus. AB - This study investigated the application of Potamogeton pectinatus for Ni(II)-ions biosorption from aqueous solutions. FTIR spectra showed that the functional groups of -OH, C-H, -C = O, and -COO- could form an organometallic complex with Ni(II)-ions on the biomaterial surface. SEM/EDX analysis indicated that the voids on the biosorbent surface were blocked due to Ni(II)-ions uptake via an ion exchange mechanism. For Ni(II)-ions of 50 mg/L, the adsorption efficiency recorded 63.4% at pH: 5, biosorbent dosage: 10 g/L, and particle-diameter: 0.125 0.25 mm within 180 minutes. A quadratic model depicted that the plot of removal efficiency against pH or contact time caused quadratic-linear concave up curves, whereas the curve of initial Ni(II)-ions was quadratic-linear convex down. Artificial neural network with a structure of 5 - 6 - 1 was able to predict the adsorption efficiency (R2: 0.967). The relative importance of inputs was: initial Ni(II)-ions > pH > contact time > biosorbent dosage > particle-size. Freundlich isotherm described well the adsorption mechanism (R2: 0.974), which indicated a multilayer adsorption onto energetically heterogeneous surfaces. The net cost of using P. pectinatus for the removal of Ni(II)-ions (4.25 +/- 1.26 mg/L) from real industrial effluents within 30 minutes was 3.4 $USD/m3. PMID- 29584468 TI - 226Ra, 238U and Cd adsorption kinetics and binding capacity of two cyanobacterial strains isolated from highly radioactive springs and optimal conditions for maximal removal effects in contaminated water. AB - Biomass-based decontamination methods are among the most interesting water treatment techniques. In this study, 2 cyanobacterial strains, Nostoc punctiforme A.S/S4 and Chroococcidiopsis thermalis S.M/S9, isolated from hot springs containing high concentrations of radium (226Ra), were studied to be associated with removal of radionuclides (238U and 226Ra) and heavy metal cadmium (Cd) from aqueous solutions. The adsorption equilibrium data was described by Langmuir and Freundlich isotherm models. Kinetic studies indicated that the sorption of 3 metals followed pseudo-second-order kinetics. Effects of biomass concentration, pH, contact time, and initial metal concentration on adsorption were also investigated. Fourier-transform infrared spectroscopy revealed active binding sites on the cyanobacterial biomass. The obtained maximum biosorption capacities were 630 mg g-1 and 37 kBq g-1 for 238U and 226Ra for N. punctiforme and 730 mg g 1 and 55 kBq g-1 for C. thermalis. These 2 strains showed maximum binding capacity 160 and 225 mg g-1, respectively for Cd adsorption. These results suggest that radioactivity resistant cyanobacteria could be employed as an efficient adsorbent for decontamination of multi-component, radioactive and industrial wastewater. PMID- 29584469 TI - Profiling of plants at petroleum contaminated site for phytoremediation. AB - The paucity of information in the literature on the characteristics of plants that could be used for phytoremediation of petroleum hydrocarbons (PHC) contaminated sites was the principal reason for this study. The aim of the study was to identify indigenous plants growing in PHC-impacted soil in Umuahia in eastern-Nigeria that have the ability to phytoremediate soils contaminated with hydrocarbons under tropical monsoon climate conditions. A total of 28 native plant species from different families growing in and around hydrocarbon-impacted soil in the vicinity of vandalized pipelines carrying petroleum products were collected and studied for their ability to grow in a hydrocarbon-impacted soil and remove the PHC from the impacted soil. Some of the plants demonstrated the ability to grow in soil with high levels of the total petroleum hydrocarbons (TPH), which shows that they may be tolerant to hydrocarbons in soil and could potentially phytoremediate a hydrocarbon-contaminated soil. Chromolaena odorata, Aspilia africana, Chloris barbata, Pasparlum vaginatum, Bryophyllum pinnatum, Paspalum scrobiculatum, Cosmos bipinnatus, Eragrostis atrovirens, Cyperus rotundus, and Uvaria chamae showed tendencies to phytoremediate contaminated soil. By using bioaccumulation coefficient (BAC) as a measure of phytoremediation, results showed that C. odorata, A. africana, and U. chamae demonstrated the highest potentials to phytodegrade hydrocarbons in soil. PMID- 29584470 TI - A natural macroalgae consortium for biosorption of copper from aqueous solution: Optimization, modeling and design studies. AB - In this study, the capacity of a natural macroalgae consortium consisting of Chaetomorpha sp., Polysiphonia sp., Ulva sp. and Cystoseira sp. species for the removal of copper ions from aqueous environment was investigated at different operating conditions, such as solution pH, copper ion concentration and contact time. These environmental parameters affecting the biosorption process were optimized on the basis of batch experiments. The experimentally obtained data for the biosorption of copper ions onto the macroalgae-based biosorbent were modeled using the isotherm models of Freundlich, Langmuir, Sips and Dubinin-Radushkevich and the kinetic models of pseudo-first-order, pseudo-second-order, Elovich and Weber and Morris. The pseudo-first-order and Sips equations were the most suitable models to describe the copper biosorption from aqueous solution. The thermodynamic data revealed the feasibility, spontaneity and physical nature of biosorption process. Based on the data of Sips isotherm model, the biosorption capacity of biosorbent for copper ions was calculated as 105.370 mg g-1 under the optimum operating conditions. A single-stage batch biosorption system was developed to predict the real-scale-based copper removal performance of biosorbent. The results of this investigation showed the potential utility of macroalgae consortium for the biosorption of copper ions from aqueous medium. PMID- 29584471 TI - Adsorption of Cd(II) by rhizosphere and non-rhizosphere soil originating from mulberry field under laboratory condition. AB - In this study, the adsorption behavior of Cd ions by rhizosphere soil (RS) and non-rhizosphere soil (NS) originated from mulberry field was investigated. The Langmuir, Freundlich and the Dubinin-Radushkevich (D-R) equations were used to evaluate the type and efficiency of Cd adsorption. The RS was characterized by lower pH but the higher content of soil organic matter and cation exchange capacity (CEC) as compared to NS. Also, the maximum adsorption of Cd2+ for RS (5.87 mg/g) was slightly bigger than that for NS (5.36 mg/g). In Freundlich isotherm, the Kf of the adsorption of Cd2+ to surface of the RS components was higher than that of the NS, indicating stronger attraction between Cd2+ and components of the RS. According to the D-R model, the adsorption of Cd2+ by both soils was dominated by ion exchange phenomena. These results indicated that mulberry roots modified physical and chemical properties of the RS under field conditions, which also affected the Cd sorption efficiency by soil components during laboratory experiments. Current knowledge of the Cd2+ sorption processes in the rhizosphere of mulberry may be important if these trees are planted for use in phytoremediation of Cd contaminated soils. PMID- 29584472 TI - Physiological and molecular responses of pearl millet seedling to atrazine stress. AB - Pearl millet has been recommended beneficial for several therapeutic purposes. However, little is known of the physiological responses to abiotic stressors, especially of atrazine. In order to elucidate the physiological and molecular responses of pearl millet to atrazine stress, we studied the response of various biomarkers under increasing herbicide concentrations (0, 5, 10, and 50 mg/kg). We also quantified the levels of malondialdehyde (MDA) and reactive oxygen species (ROS) (H2O2 and O2*-) produced in the leaves to evaluate the extent of oxidative damage. Increasing atrazine concentrations significantly increased ROS and MDA production in the plant leaves. Ascorbate peroxidase (APX) and peroxidase (POD) activities increased, while catalase (CAT) and superoxide dismutase activities reduced with increasing atrazine concentrations. Generally, atrazine applied at 50 mg/kg suppressed chlorophyll contents, whereas, chlorophyll (a/b) ratio was increased. Atrazine applied at 50 mg/kg significantly suppressed antioxidant gene expressions to the lowest. The APX gene showed overall low response to the atrazine treatments. The chloroplastic psbA gene showed highest expression with 10 mg/kg atrazine, whereas atrazine at 50 mg/kg significantly suppressed the gene expression to its lowest. Pearl millet was able to suppress oxidative stress under low atrazine levels, but high atrazine concentration could induce more oxidative damage. PMID- 29584473 TI - Analysis of near crashes among teen, young adult, and experienced adult drivers using the SHRP2 naturalistic driving study. AB - OBJECTIVE: Motor vehicle crashes are the leading cause of death among young drivers. Though previous research has focused on crash events, near crashes offer additional data to help identify driver errors that could potentially lead to crashes as well as evasive maneuvers used to avoid them. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) contains extensive data on real-world driving and offers a reliable methodology to quantify and study near crashes. This article presents findings on near crashes and how they compare to crash events among teen, young adult, and experienced adult drivers. METHODS: A subset from the SHRP2 database consisting of 1,653 near crashes for teen (16-19 years, n = 550), young adult (20-24 years, n = 748), and experienced adult (35-54 years, n = 591) drivers was used. Onboard instrumentation including scene cameras, accelerometers, and Global Positioning System logged time series data at 10 Hz. Scene videos were reviewed for all events to classify near crashes based on 7 types: rear-end, road departure, intersection, head-on, side-swipe, pedestrian/cyclist, and animal. Near crash rates, incident type, secondary tasks, and evasive maneuvers were compared across age groups and between crashes and near crashes. For rear-end near crashes, vehicle dynamic variables including near crash severity, headway distance, time headway, and time to collision at the time of braking were compared across age groups. Crashes and near crashes were combined to compare the frequency of critical events across age. RESULTS: Teen drivers exhibited a significantly higher (P <.01) near crash rate than young adult and experienced adult drivers. The near crash rates were 81.6, 56.6, and 37.3 near crashes per million miles for teens, young adults, and experienced adults, respectively. Teens were also involved in significantly more rear-end (P <.01), road departure (P <.01), side-swipe (P <.01), and animal (P <.05) near crashes compared to young and experienced adults. Teens exhibited a significantly greater (P <.01) critical event rate of 102.2 critical events per million miles compared to 72.4 and 40.0 critical events per million miles for young adults and experienced adults, respectively; the critical event rate ratio was 2.6 and 1.8 for teens and young adults, respectively. CONCLUSIONS: To our knowledge, this is the first study to examine near crashes among teen, young adult, and experienced adult drivers using SHRP2 naturalistic data. Near crash and critical event rates significantly decreased with increasing age and driver experience. Overall, teens were more than twice as likely to be involved in critical events compared to experienced adults. These data can be used to develop more targeted driver training programs and help manufacturers design active safety systems based on the most common driving errors for vulnerable road users. PMID- 29584474 TI - The extent of backover collisions internationally. AB - This study reports good consistency in international comparisons of the number and severity of backover crashes. More than half occurred to pedestrians aged 60 years and older. Children less than 9 years comprised 5% of these crashes with a similar percent aged 10 to 19 years. A significant 41% reduction in real-world backover crashes was found for Australian vehicles with reversing cameras. A range of driver and pedestrian maneuvers was found and 11 crash scenarios were identified in backover collisions. Mandating the fitting of reversing cameras to all vehicles and enhancements would likely enhance the safety of pedestrians in reversing maneuvers. PMID- 29584475 TI - Occupant kinematics of the Hybrid III, THOR-M, and postmortem human surrogates under various restraint conditions in full-scale frontal sled tests. AB - OBJECTIVE: The objective of this research was to compare the occupant kinematics of the Hybrid III (HIII), THOR-M, and postmortem human surrogates (PMHS) during full-scale frontal sled tests under 3 safety restraint conditions: knee bolster (KB), knee bolster and steering wheel airbag (KB/SWAB), and knee bolster airbag and steering wheel airbag (KBAB/SWAB). METHODS: A total of 20 frontal sled tests were performed with at least 2 tests performed per restraint condition per surrogate. The tests were designed to match the 2012 Toyota Camry New Car Assessment Program (NCAP) full-scale crash test. Rigid polyurethane foam surrogates with compressive strength ratings of 65 and 19 psi were used to simulate the KB and KBAB, respectively. The excursions of the head, shoulders, hips, knees, and ankles were collected using motion capture. Linear acceleration and angular velocity data were also collected from the head, thorax, and pelvis of each surrogate. Time histories were compared between surrogates and restraint conditions using ISO/TS 18571. RESULTS: All surrogates showed some degree of sensitivity to changes in restraint condition. For example, the use of a KBAB decreased the pelvis accelerations and the forward excursions of the knees and hips for all surrogates. However, these trends were not observed for the thorax, shoulders, and head, which showed more sensitivity to the presence of a SWAB. The average scores computed using ISO/TS 18571 for the HIII/PMHS and THOR-M/PMHS comparisons were 0.527 and 0.518, respectively. The HIII had slightly higher scores than the THOR-M for the excursions (HIII average = 0.574; THOR average = 0.520). However, the THOR-M had slightly higher scores for the accelerations and angular rates (HIII average = 0.471; THOR average = 0.516). CONCLUSIONS: The data from the current study showed that both KBABs and SWABs affected the kinematics of all surrogates during frontal sled tests. The results of the objective rating analysis indicated that the HIII and THOR-M had comparable overall biofidelity scores. The THOR-M slightly outperformed the HIII for the acceleration and angular velocity data. However, the HIII scored slightly better than the THOR-M for the excursion data. The most notable difference in biofidelity was for the knee excursions, where the HIII had a much higher average ISO score. Only the biofidelity of the HIII and THOR-M with regard to occupant kinematics was evaluated in this study; therefore, future work will evaluate the biofidelity of the ATDs in terms of lower extremity loading, thoracic response, and neck loading. PMID- 29584476 TI - Advanced driver assistance systems for teen drivers: Teen and parent impressions, perceived need, and intervention preferences. AB - OBJECTIVE: From the advent of airbags to electronic stability control, technological advances introduced into automobile design have significantly reduced injury and death from motor vehicle crashes. These advances are especially pertinent among teen drivers, a population whose leading cause of death is motor vehicle crashes. Recently developed advanced driver assistance systems (ADAS) have the potential to compensate for skill deficits and reduce overall crash risk. Yet, ADAS is only effective if drivers are willing to use it. Limited research has been conducted on the suitability of ADAS for teen drivers. The goal of this study is to identify teen drivers' perceived need for ADAS, receptiveness to in-vehicle technology, and intervention preferences. The long term goal is to understand public perceptions and barriers to ADAS use and to help determine how these systems must evolve to meet the needs of the riskiest driving populations. METHODS: Three focus groups (N = 24) were conducted with licensed teen drivers aged 16-19 years and 2 focus groups with parents of teen drivers (N = 12). Discussion topics included views on how ADAS might influence driving skills and behaviors; trust in technology; and data privacy. Discussions were transcribed; the team used conventional content analysis and open coding methods to identify 12 coding domains and code transcripts with NVivo 10. Interrater reliability testing showed moderate to high kappa scores. RESULTS: Overall, participants recognized potential benefits of ADAS, including improved safety and crash reduction. Teens suggested that ADAS is still developing and therefore has potential to malfunction. Many teens reported a greater trust in their own driving ability over vehicle technology. They expressed that novice drivers should learn to drive on non-ADAS-equipped cars and that ADAS should be considered a supplemental aid. Many teens felt that overreliance on ADAS may increase distracted driving or risky behaviors among teens. Parents also expressed skepticism for the technology but felt that it would likely be a useful support for teen drivers after the initial learning phase. CONCLUSIONS: This study elicited important end-user viewpoints by exploring the intersection between advanced automobile safety technology and human perception for the particular use case of teen drivers. For example, despite evidence that teens are the highest risk driving population, teens trust their own driving skills and competence more than in-vehicle technology. This understanding will ultimately advance the safety of teen drivers by identifying barriers to effective ADAS use. PMID- 29584477 TI - Failed rib region prediction in a human body model during crash events with precrash braking. AB - OBJECTIVE: The objective of this study is 2-fold. We used a validated human body finite element model to study the predicted chest injury (focusing on rib fracture as a function of element strain) based on varying levels of simulated precrash braking. Furthermore, we compare deterministic and probabilistic methods of rib injury prediction in the computational model. METHODS: The Global Human Body Models Consortium (GHBMC) M50-O model was gravity settled in the driver position of a generic interior equipped with an advanced 3-point belt and airbag. Twelve cases were investigated with permutations for failure, precrash braking system, and crash severity. The severities used were median (17 kph), severe (34 kph), and New Car Assessment Program (NCAP; 56.4 kph). Cases with failure enabled removed rib cortical bone elements once 1.8% effective plastic strain was exceeded. Alternatively, a probabilistic framework found in the literature was used to predict rib failure. Both the probabilistic and deterministic methods take into consideration location (anterior, lateral, and posterior). The deterministic method is based on a rubric that defines failed rib regions dependent on a threshold for contiguous failed elements. The probabilistic method depends on age-based strain and failure functions. RESULTS: Kinematics between both methods were similar (peak max deviation: DeltaXhead = 17 mm; DeltaZhead = 4 mm; DeltaXthorax = 5 mm; DeltaZthorax = 1 mm). Seat belt forces at the time of probabilistic failed region initiation were lower than those at deterministic failed region initiation. The probabilistic method for rib fracture predicted more failed regions in the rib (an analog for fracture) than the deterministic method in all but 1 case where they were equal. The failed region patterns between models are similar; however, there are differences that arise due to stress reduced from element elimination that cause probabilistic failed regions to continue to rise after no deterministic failed region would be predicted. CONCLUSIONS: Both the probabilistic and deterministic methods indicate similar trends with regards to the effect of precrash braking; however, there are tradeoffs. The deterministic failed region method is more spatially sensitive to failure and is more sensitive to belt loads. The probabilistic failed region method allows for increased capability in postprocessing with respect to age. The probabilistic failed region method predicted more failed regions than the deterministic failed region method due to force distribution differences. PMID- 29584478 TI - Driving style indicator using UDRIVE NDS data. AB - OBJECTIVE: In order to analyze specific events while driving (such as a safety critical event [SCE] or secondary task), we were interested in studying whether driving behavior was unusual around the event. An indicator characterizing driving style (driving style indicator [DSI]) was estimated for each driver by using naturalistic data. The analysis of the gap in driving style could be calculated for a specific trip or even a time window and could help characterize events: a more risky situation when DSI was above average, increase in safety margins when under average. METHODS: Lateral acceleration and longitudinal acceleration were used for DSI calculation. The first step consisted in filtering the signal acquired by the inertial measurement unit (60 Hz). The noise was filtered out with an eighth order, phase-compensated digital low-pass Butterworth filter with a cut-out frequency of 5 Hz and offsets were compensated for. The second step consisted in calculating the jerk of the acceleration in lateral and longitudinal directions for each trip. The third step summarized the distribution of these jerks for all trips of each driver. Finally, the DSI was defined as the standard deviation of this distribution. A driver was represented by lateral DSI and longitudinal DSI. RESULTS: The indicator was used on French pilot data (10 drivers) and on UK data (30 drivers) from the UDRIVE project. To assess this indicator, tests on track were conducted by professional drivers simulating two opposite driving style. The first results were promising and discriminated a smooth from a rough driving style. Indeed, in the pilot data, the classification was in accordance with our expectations and confirmed by videos. The same kind of distribution was observed in the UK data and needs to be confirmed when the UDRIVE database is complete. CONCLUSION: DSI is a new parameter that will be used to define clusters of drivers and study variation of driving parameters in each class during selected events (SCE, secondary task, etc.) in the UDRIVE project. PMID- 29584479 TI - Injury risk functions based on population-based finite element model responses: Application to femurs under dynamic three-point bending. AB - OBJECTIVE: The goal of this study was to explore a framework for developing injury risk functions (IRFs) in a bottom-up approach based on responses of parametrically variable finite element (FE) models representing exemplar populations. METHODS: First, a parametric femur modeling tool was developed and validated using a subject-specific (SS)-FE modeling approach. Second, principal component analysis and regression were used to identify parametric geometric descriptors of the human femur and the distribution of those factors for 3 target occupant sizes (5th, 50th, and 95th percentile males). Third, distributions of material parameters of cortical bone were obtained from the literature for 3 target occupant ages (25, 50, and 75 years) using regression analysis. A Monte Carlo method was then implemented to generate populations of FE models of the femur for target occupants, using a parametric femur modeling tool. Simulations were conducted with each of these models under 3-point dynamic bending. Finally, model-based IRFs were developed using logistic regression analysis, based on the moment at fracture observed in the FE simulation. In total, 100 femur FE models incorporating the variation in the population of interest were generated, and 500,000 moments at fracture were observed (applying 5,000 ultimate strains for each synthesized 100 femur FE models) for each target occupant characteristics. RESULTS: Using the proposed framework on this study, the model-based IRFs for 3 target male occupant sizes (5th, 50th, and 95th percentiles) and ages (25, 50, and 75 years) were developed. The model-based IRF was located in the 95% confidence interval of the test-based IRF for the range of 15 to 70% injury risks. The 95% confidence interval of the developed IRF was almost in line with the mean curve due to a large number of data points. CONCLUSIONS: The framework proposed in this study would be beneficial for developing the IRFs in a bottom-up manner, whose range of variabilities is informed by the population-based FE model responses. Specifically, this method mitigates the uncertainties in applying empirical scaling and may improve IRF fidelity when a limited number of experimental specimens are available. PMID- 29584480 TI - Kinematics and shoulder belt engagement of children on belt-positioning boosters during evasive steering maneuvers. AB - OBJECTIVE: To increase the protection of child passengers in crashes preceded by evasive steering, understanding of how children interact with the seat belt in such situations is essential. This study aims to quantify child kinematics and describe child-to-restraint interaction during evasive steering maneuvers. METHODS: Eighteen child volunteers (aged 5-10) were seated on the rear seat of a passenger vehicle. A professional driver made repeatable sharp turns at 50 km/h. Children were restrained by the seat belt on a booster cushion (BC) and on an integrated booster cushion (IBC). Kinematics of the nasion and upper sternum were analyzed with video tracking software and shoulder belt (SB) engagement and position were evaluated. RESULTS: Children moved laterally inboard, and SB-to body interaction was influenced by booster and stature. Shorter children displayed initial SB positions closer to the neck with less instances of gap between the SB and the lower torso, resulting in more curved belt paths on the IBC. On the BC, shorter children had less of the SB in contact with the torso and straight belt paths were observed throughout steering. Taller children generally had the SB initially mid-shoulder with less instances of gap, resulting in curved belt paths at initial and maximum displacements on both boosters. Children loaded the shoulder belt by axially rotating their torso into the SB more often on the IBC compared to BC. The SB generally stayed on the shoulder, with 89% of slip-off instances occurring for shorter children on the BC. Shorter children on the BC had the largest average inboard nasion displacement (120 mm). Taller children on the BC had the lowest average inboard displacement of the nasion (100 mm). All children initially displaced on average 90 mm inboard with their upper sternum. CONCLUSIONS: Initial SB position on the shoulder and torso differed with booster and stature, which influenced how children engaged with the seat belt during steering. Children with less SB initially in contact with the torso moved laterally behind the belt, resulting in straighter SB paths and outboard motion of the SB on the shoulder (often ending far out or slipped off). When more of the SB was initially in contact with the torso, children tended to engage the SB more, moving with the belt and causing the SB path to become more curved, resulting in less inboard head displacement and less outboard motion of the SB on the shoulder. Enhanced understanding of how evasive steering affects the kinematic response of children provides valuable data for protection of children in real-world situations. PMID- 29584481 TI - The effectiveness of child restraint and seat belt legislation in reducing child injuries: The case of Serbia. AB - OBJECTIVE: The objective of this study is to determine the short- and long-term impacts of Serbia's 2009 update of child restraint and seat belt legislation on the incidence of pediatric motor vehicle-related injury. With this new law, the use of child restraints in children age 0-3 became mandatory, and children 4-12 had to wear seat belts in the rear seats. METHODS: A unique data set with assembled information from public institutions of the Republic of Serbia from January 2004 to December 2014 and analyses based on interrupted time series were carried out. Eight outcome variables were assessed: monthly rate of injured children for 2 age groups 0-3 and 4-12 per child population, number of registered motor vehicles, number of passengers transported, and number of passengers' kilometers traveled. Independent variables were short- and long-term impacts of Serbia's legislation update (June 2009). Data on injuries were obtained from Serbia's Road Traffic Safety Agency. Child population and other transport-related data were obtained from the Statistical Office of the Republic of Serbia. We excluded fatalities from the analysis. RESULTS: In the first year of the updated legislation there was a reduction of 2.0% (confidence interval [CI], 0.1; 3.9) of injured children aged 0-3 and a reduction of 2.5% (CI, 0.6; 4.3) of injured children aged 4-12. Six years after enactment of the legislation, a significant reduction of 8.2% (CI, 3.5; 13.0) of injured children aged 4-12 was observed, but a nonsignificant reduction of 1.1% (CI, -5.8; 3.5) was found for injured children aged 0-3. By December 2014, 369 (CI, 186; 555) injuries among children aged 4-12 were avoided. CONCLUSIONS: The case of Serbia suggests that the new law was effective in reducing injuries among children aged 0-3 in the short term and injuries among children aged 4-12 in both the short term and long term. To understand these results, we suggest 2 hypotheses. First, low proper usage of child restraint and weak police enforcement were likely to explain the short-term effect among children aged 0-3. Second, access to seat belts in rear seats was probably a condition that facilitated the use of these devices among children aged 4-12, protecting them during the period of the study. PMID- 29584482 TI - An evaluation of the real-world safety effect of a lane change driver support system and characteristics of lane change crashes based on insurance claims data. AB - OBJECTIVE: Lane changes, which frequently occur when vehicles travel on major roads, may contribute to critical situations that significantly affect the traffic flow and traffic safety. Thus, knowledge of lane change situations is important for infrastructure improvements as well as for driver support systems and automated driving development projects. The objectives of this study were to evaluate the crash avoidance performance of a lane change driver support system, the Blind Spot Information System (BLIS) in Volvo car models, and to describe the characteristics of lane change crashes by analyzing detailed information from insurance claim reports. METHODS: An overall evaluation of the safety effect of BLIS was performed by analyzing crash rate differences in lane change situations for cars with and without the optionally mounted BLIS system based on a population of 380,000 insured vehicle years. Further, crashes in which the repair cost of the host vehicle exceeded approximately US$1,250 were selected and compared. Finally, the study examined different precrash factors and crash configurations, using in-depth insurance claims data from representative lane change crash cases including all severity levels in a population of more than 200,000 insured vehicle years. RESULTS: The technology did not significantly reduce the overall number of crashes when all types of lane change crashes and severity levels were considered, though a significant crash-reducing effect of 31% for BLIS cars was found when more severe crashes with a repair cost exceeding US$1,250 were analysed. Cars with the BLIS technology also have a 30% lower claim cost on average for reported lane change crashes, indicating reduced crash severity. When stratifying the data into specific situations, by collecting precrash information in a case-by-case study, the influence of BLIS was indicated to differ for the evaluated situations, although no significant results were found. For example, during general lane change maneuvers (i.e., not while exiting or entering highways or during weaving/merging situations) the crash rate was reduced by 14%, whereas in weaving/merging situations the crash rate increased. CONCLUSIONS: The insurance data analyzed provided useful information about real world lane change crash characteristics by covering collisions in all crash severities and thus revealed information beyond what is available in, for example, data sets of police-reported crashes. This will guide further development of driver support systems. For crashes with repair cost exceeding US$1,250, a significant crash reduction was found, although the technology did not significantly reduce the total number of lane change crashes. An average lower insurance claim cost for cars equipped with the BLIS technology also indicated that the technology contributes to reduced crash severity even if crashes were not totally avoided. Stratifying the data into different lane change crash situations gave indications of the condition-specific performance of the system, even if the results were not statistically significant at the 95% level. PMID- 29584483 TI - Injury analysis of patients according to impact patterns involved in pedestrian traffic crashes. AB - OBJECTIVES: In cases of car-to-person pedestrian traffic crashes (PTCs), the principal issue is determining at what point the car collided with the pedestrian. Accordingly, the objective of the present study was to use the medical records of patients injured in PTCs to investigate the characteristics of crash types and the areas and injury severity and to determine whether there are differences in injuries due to the angle, motion, and position at the point of impact. METHODS: The present study examined 231 PTC patients admitted to the emergency room (ER) between January and December 2014. Electronic medical records from the hospital were used to divide the patient data according to Abbreviated Injury Scale (AIS) codes for injured areas based on sex, age, time of the crash, outcomes after ER treatment, and major symptoms. Among 231 patients, police reports on 67 crash cases, involving 70 people, were obtained with the help of local police departments, and these reports were used to reconstruct details of the actual crash. For statistical analysis, a chi-square test and a one-way analysis of variance calculation were used to compare the Injury Severity Score (ISS) based on groups and stages, with a statistical significance level set to P < .05. RESULTS: With respect to patients who were admitted for PTC, 52.4% were females and 47.6% were males. The frequency of crashes was high in middle-aged and elderly groups, as well as for youths between 10 and 19 years old. With respect to outcomes after ER treatment, discharge to home after symptom improvement was the most common outcome (24.6%). Admissions to the intensive care unit (25.1%) and to the general ward (23.8%) were also high. In terms of major symptoms, the most common injuries were to the head, resulting from a rotatory motion post impact (35.9%), and injuries to the legs, resulting from the impact of a direct collision with an object (25.1%). CONCLUSIONS: This study demonstrated that injuries to the chest and abdomen were the most severe in the fender vault group and head and neck injuries were the most severe in the roof vault group. In particular, the Injury Severity Score was highest in the roof vault group. PMID- 29584484 TI - Cyclist exposure to the risk of car door collisions in mixed function activity centers: A study in Melbourne, Australia. AB - OBJECTIVE: The objective of this study is to describe key risks related to dooring collisions on roads in mixed function activity centers by examining video footage recorded onboard the bicycles of cyclists riding through this road environment. The study aims to enhance our understanding of the risk associated with cyclist door collisions on these roads and to provide a focus for future studies that aim to identify measures that enhance cyclist safety. METHOD: The study measured 4 key risk exposures (per hour and kilometer), namely, on-street parked cars and 3 conditions associated with parked cars being accessed or egressed: door opened (a) after the cyclist passes (give-way event); (b) in the path of the cyclist without collision (obstruction event); and (c) in the path of the cyclist with collision (collision event). Exposure to the risk factors was measured using video footage recorded onboard the bicycles of adult cyclists (n = 25) as they rode through this road environment. The average speed of cyclists was also estimated from these video data and related to the measures of exposure. RESULTS: The cycling experiences of the participants were observed over 3 h 58 min and 84.0 km. On average, the sample was exposed to 1,166 parked car events per hour (55 per kilometer), 6.9 give-way events per hour (0.3 per kilometer), 2.3 obstruction events per hour (0.1 per kilometer), and no collision events. There were 9 instances of obstruction events. In most cases, the cyclist was clearly visible (n = 7; 77.8%) and modified his or her position to avoid the door (n = 8; 88.9%). Moreover, the door was opened by the driver in nearly all cases (n = 8; 88.9%), primarily to exit the vehicle (n = 4; 44.4%) or enter the vehicle (n = 3; 33.3%). The average speed of cyclists was 22.7 km/h (SD = 4.1 km/h), and average speed tended to reduce as exposure to parked car events increased. CONCLUSION: Cyclists seldom interact with a vehicle occupant accessing or egressing a parked car, yet a concerning proportion of these interactions involve the occupant opening the door in the path of the cyclist, rather than waiting for the cyclist to pass. This suggests that there is still considerable need to identify measures that increase the likelihood that a vehicle occupant will look for cyclists before opening the car door, particularly in road environments where longer-term solutions such as physical separation are not readily achieved. PMID- 29584485 TI - Evaluation of a combination of community initiatives to reduce driving while intoxicated and other alcohol-related harms. AB - OBJECTIVES: In 2013, the community of Redlands, California, created an initiative using evidence-based strategies to deter driving under the influence (DUI), underage drinking and driving, public intoxication, and alcohol-related calls for service. The initiative, called "Responsible Redlands," included adopting a social host and a deemed approved local ordinance, using minor-decoy and shoulder tap operations, increasing sobriety checkpoints and saturation patrols, conducting responsible beverage service (RBS) training, using identification (ID) scanners to spot false IDs, and a publicity campaign to urge neighbors to report loud drinking parties. The objectives of this study were to determine whether the initiatives were carried out as planned and to assess any impacts that may have occurred due to the combination of initiatives. METHODS: Data from the Redlands Police Department were used to assess the process evaluation. The Statistical Analysis System (SAS) was used to create contingency tables to compare before (2007-2012) and after (2013-2014) the intervention start date and to conduct time series analyses and calculate chi-squared test statistics on five outcome measures: DUI arrests, underage drinking violations, public intoxication violations, alcohol calls for service, and place of last drink (POLD) data from alcohol violators. Data sources were from the Redlands Police Department: DUI arrests for drivers under age 21 years and drivers age 21 or older; alcohol related calls for service; public intoxication citations; and place of last drink surveys. Comparable data from control communities in California were not available at the time of the analyses. RESULTS: Responsible Redlands Initiatives appeared to be carried out as planned. There was a statistically significant decrease in DUI arrests for drivers 21 and older from preintervention to postintervention (p < .001), in alcohol-related calls for service (p < .001), in loud music calls for service (p = .06), and in public intoxication citations (p < .001). There were decreases in underage drinking violations and in DUIs for under age 21 drivers, but the numbers were too small for chi-squared statistical tests. CONCLUSIONS: "Responsible Redlands" interventions were associated with several significant decreases in outcome measures from preintervention to postintervention. Communities that consider these initiatives in combination (social host and deemed approved ordinances; minor-decoy and shoulder-tap operations; DUI checkpoints and saturation patrols; RBS training; use of ID scanners and a public information campaign to report loud drinking parties) can expect to experience potential decreases in alcohol-related harm. PMID- 29584486 TI - Novel method of estimating AROC using an injury risk curve for biomechanical injury metric selection. AB - OBJECTIVE: Area under the receiver operating characteristic (AROC) is commonly used to evaluate an injury metric's ability to discriminate between injury and noninjury cases. However, AROC has limitations and may not handle censored data sets adequately. Survival methodology creates robust estimates of injury risk curves (IRCs) which accommodate censored data. We developed an observation adjusted ROC (oaROC), an AROC-like statistic calculated from the IRC. METHODS: oaROC uses an observational distribution and an IRC to measure true positive rate (TPR) and false positive rate (FPR). The oaROC represents what the AROC would be with a large number of observations sampled from the IRC. We verified this using a limit test with simulated data sets at various sample sizes drawn from an assumed "true" IRC. For each sample size, 5,000 different data sets were created; a conventional AROC was calculated for each data set and compared with the single oaROC, which was calculated from the "true" IRC and not dependent on sample size. RESULTS: The oaROC, calculated from the simulated IRC, was 0.911. At a sample size of 20, the mean AROC was 0.930 (2.0% difference). At a sample size of 1,000, the mean AROC was 0.9114 (0.02% difference). CONCLUSION: We verified that AROC approaches the oaROC with increasing sample sizes, and oaROC presents a measure of IRC discriminatory ability. Survival methodology can estimate IRCs using censored observations and the oaROC was designed with this in mind. The oaROC may be a useful measure of discrimination for data sets containing censored data. Further investigation is needed to evaluate oaROC calculated from estimated IRCs. PMID- 29584487 TI - Comparison of outlier heartbeat identification and spectral transformation strategies for deriving heart rate variability indices for drivers at different stages of sleepiness. AB - OBJECTIVE: Appropriate preprocessing for detecting and removing outlier heartbeats and spectral transformation is essential for deriving heart rate variability (HRV) indices from cardiac monitoring data with high accuracy. The objective of this study is to evaluate agreement between standard preprocessing methods for cardiac monitoring data used to detect outlier heartbeats and perform spectral transformation, in relation to estimating HRV indices for drivers at different stages of sleepiness. METHODS: The study analyzed more than 3,500 5-min driving epochs from 76 drivers on a public motorway in Sweden. Electrocardiography (ECG) data were recorded in 3 studies designed to evaluate the physiological differences between awake and sleepy drivers. The Pan-Tompkins algorithm was used for peak detection of heartbeats from ECG data. Two standard methods were used for identifying outlier heartbeats: (1) percentage change (PC), where outliers were defined as interbeat interval deviating >30% from the mean of the 4 previous intervals, and (2) standard deviation (SD), where outliers were defined as interbeat interval deviating >4 SD from the mean interval duration in the current epoch. Three standard methods were used for spectral transformation, which is needed for deriving HRV indices in the frequency domain; these methods were (1) the Fourier transform; (2) an autoregressive model; and (3) the Lomb Scargle periodogram. The preprocessing methods were compared quantitatively and by assessing agreement between estimations of 13 common HRV indices using Bland Altman plots and paired Student's t-tests. RESULTS: The PC method detected more than 4 times as many outliers (0.28%) than SD (0.065%). Most HRV indices derived using different preprocessing methods exhibited significant systematic (P <.05) and substantial random variations. CONCLUSIONS: The standard preprocessing methods for HRV data for outlier heartbeat detection and spectral transformation show low levels of agreement. This finding implies that, prior to designing algorithms for detection of sleepy drivers based on HRV analysis, the impact of different preprocessing methods and combinations thereof on driver sleepiness assessment needs to be studied. PMID- 29584488 TI - Functional outcomes of thoracic injuries in pediatric and adult occupants. AB - OBJECTIVE: To develop a disability metric for motor vehicle crash (MVC) thoracic injuries and compare functional outcomes between pediatric and adult populations. METHODS: Disability risk (DR) was quantified using Functional Independence Measure (FIM) scores within the National Trauma Data Bank (NTDB) for the top 95% most frequently occurring AIS 2, 3, 4, and 5 thoracic injuries in NASS-CDS 2000 2011. The NTDB contains a truncated form of the FIM score, including three items (self-feed, locomotion, and verbal expression), each graded from full functional dependence to full functional independence. Pediatric (ages 7-18 years), adult (19-45), middle-aged adult (46-65), and older adult (66+) MVC occupants were classified as disabled or not disabled based on the FIM scale. The DR was calculated for each injury within each age group by dividing the number of patients who were disabled that sustained the specific injury by the number of patients who sustained the specific injury. To account for the impact of more severe co-injuries, a maximum Abbreviated Injury Scale (MAIS) adjusted DR (DRMAIS) was also calculated. DR and DRMAIS could range from 0 (0% disability risk) to 1 (100% disability risk). RESULTS: The mean DRMAIS for MVC thoracic injuries was 20% for pediatric occupants, 22% for adults, 29% for middle-aged adults, and 43% for older adults. Older adults possessed higher DRMAIS values for diaphragm laceration/rupture, heart laceration, hemo/pneumothorax, lung contusion/laceration, rib fracture, and sternum fracture compared to the other age groups. The pediatric population possessed a higher DRMAIS value for flail chest compared to the other age groups. CONCLUSIONS: Older adults had significantly greater overall disability than each of the other age groups for thoracic injuries. The developed disability metrics are important in quantifying the significant burden of injuries and loss of quality life years. Such metrics can be used to better characterize severity of injury and further the understanding of age-related differences in injury outcomes, which can impact future age-specific modifications to AIS. PMID- 29584489 TI - Trends in child passenger safety practices in Indiana from 2009 to 2015. AB - OBJECTIVE: This study reviews trends in rear-facing direction, top tether use, booster seat use, and seating position for children 12 years or younger among motor vehicle passengers in Indiana. METHODS: This is an observational, cross sectional survey of drivers transporting children 15 years and younger collected at 25 convenience locations randomly selected in Indiana during summers of 2009 2015. Observations were conducted by certified child passenger safety technicians (CPST). As the driver completed a written survey collecting demographic data on the driver, the CPST recorded the child demographic data, vehicle seating location, the type of restraint, direction the car safety seat (CSS) was facing, and use of the CSS harness or safety belt as appropriate. Data were analyzed for infants and toddlers younger than 24 months, children in forward-facing CSS, booster seat use, and seating position for children 12 years or younger. RESULTS: During the study period, 4,876 drivers were queried, and 7,725 children 15 years and younger were observed in motor vehicles. Between 2009 and 2015, 1,115 infants and toddlers (age birth to 23 months) were observed in motor vehicles. For infants <1 year, rear-facing increased from 84% to 91%. During the study years the greatest increase in rear facing was for toddlers age 12-17 months (12-61%). Rear facing for those from 18-23 months did not significantly change. Of the 1,653 vehicles observed with a forward-facing car seat, using either the seat belt system or lower anchors, an average of 27% had the top tether attached. For installations of forward-facing seats using the lower anchor, 66% employed the top tether. Among children age 4-7 years observed booster seat use decreased from 72% to 65% during the observation period. Finally, for vehicle seating position, in our sample, more than 85% of children 12 years or younger were seated in a rear seat vehicle position. Unfortunately, 31% of 8- to 12-year-old children were observed in the front seat. CONCLUSIONS: Overall, these trends demonstrate an improvement in child passenger safety practices among Indiana drivers. However, this study illuminates areas to improve child passenger safety, such as rear facing for toddlers 18 to 23 months, increasing top tether use, booster seat use, and an emphasis on rear seat position for children 8 to 12 years. This information can be used by primary care providers and child passenger safety technicians and other child passenger safety advocates to develop counseling points and targeted educational campaigns. PMID- 29584490 TI - Does obesity affect the position of seat belt loading in occupants involved in real-world motor vehicle collisions? AB - OBJECTIVE: Previous work has shown that the lap belt moves superior and forward compared to the bony pelvis as body mass index (BMI) increases. The goal of this project was to determine whether the location of lap belt loading is related to BMI for occupants who sustained real-world motor vehicle collisions (MVCs). METHODS: A national MVC database was queried for vehicle occupants over a 10-year period (2003-2012) who were at least 16 years old, restrained by a 3-point seat belt, sitting in the front row, and involved in a front-end collision with a change in velocity of at least 56 km/h. Cases were excluded if there was not an available computed tomography (CT) scan of the abdomen. CT scans were then analyzed using adipose enhancement of 3-dimensional reconstructions. Scans were assessed for the presence a radiographic seat belt sign (rSBS), or subcutaneous fat stranding due to seat belt loading. In scans in which the rSBS was present, anterior and superior displacement of rSBS from the anterior-superior iliac spine (ASIS) was measured bilaterally. This displacement was correlated with BMI and injury severity. RESULTS: The inclusion and exclusion criteria yielded 151 cases for analysis. An rSBS could definitively be identified in 55 cases. Cases in which occupants were older and had higher BMI were more likely to display an rSBS. There was a correlation between increasing BMI and anterior rSBS displacement (P <.01 and P <.01, right and left, respectively). There was no significant correlation between BMI and superior displacement of the rSBS (P =.46 and P =.33, right and left, respectively). When the data were examined in terms of relating increasing superior displacement of the lap belt with Injury Severity Scale (P =.34) and maximum Abbreviated Injury Score (AIS) injury severity (P =.63), there was also no significant correlation. CONCLUSION: The results from this study demonstrated that anterior displacement of the radiographic seat belt sign but not superior displacement increased with higher BMI. These results suggest that obesity may worsen horizontal position but not the vertical position of the lap belt loading during real-world frontal MVCs. PMID- 29584491 TI - Active muscle response contributes to increased injury risk of lower extremity in occupant-knee airbag interaction. AB - OBJECTIVE: Recent field data analysis has demonstrated that knee airbags (KABs) can reduce occupant femur and pelvis injuries but may be insufficient to decrease leg injuries in motor vehicle crashes. An enhanced understanding of the associated injury mechanisms requires accurate assessment of physiological-based occupant parameters, some of which are difficult or impossible to obtain from experiments. This study sought to explore how active muscle response can influence the injury risk of lower extremities during KAB deployment using computational biomechanical analysis. METHODS: A full-factorial matrix, consisting of 48 finite element simulations of a 50th percentile occupant human model in a simplified vehicle interior, was designed. The matrix included 32 new cases in combination with 16 previously reported cases. The following influencing factors were taken into account: muscle activation, KAB use, KAB design, pre impact seating position, and crash mode. Responses of 32 lower extremity muscles during emergency braking were replicated using one-dimensional elements of a Hill type constitutive model, with the activation level determined from inverse dynamics and validated by existing volunteer tests. Dynamics of unfolding and inflating of the KABs were represented using the state-of-the-art corpuscular particle method. Abbreviated Injury Scale (AIS) 2+ injury risks of the knee-thigh hip (KTH) complex and the tibia were assessed using axial force and resultant bending moments. With all simulation cases being taken together, a general linear model was used to assess factor significance (P <.05). RESULTS: As estimated by the regression model across all simulation cases, use of KABs significantly reduced axial femur forces by 4.74 +/- 0.43 kN and AIS 2+ injury risk of KTH by 47 +/- 6% (P <.05) but did not provide substantial change to injury risk of leg fractures. Muscle activation significantly increased axial force and bending moment of the femur (3.87 +/- 0.38 kN and 64.3 +/- 5.9 Nm), the tibia (1.49 +/- 0.12 kN and 43.0 +/- 6.4 Nm), and the resultant probability of AIS 2+ tibia injuries by 36 +/- 6% regardless of KAB use and crash scenario. Specifically, when counting on a relative scale, muscle activation exhibited more prominent elevation of injury risk for in-position occupants than out-of-position occupants. In a representative crash scenario-that is, using a bottom-deployed KAB in a nearside oblique impact-muscle bracing of the right leg may lead to 2.6 times higher tibia fracture risk than being relaxed for an out-of-position occupant and 5.4 times higher for an in-position occupant. DISCUSSION AND CONCLUSIONS: The mechanism of higher leg injuries in the presence of KAB deployment in real-world crashes can be interpreted by the increased effective body mass, axial compression along the shafts of long bones, and altered pre impact posture due to muscle contraction. The present analysis suggests that active muscle response can increase the risk of lower extremity injury during occupant-KAB interaction. This study demonstrated the feasibility of advanced human models to investigate the influence of physiologically based parameters on injury outcomes evidenced in field study and insight from computational examination on human variability for development of future restraint systems. Future efforts are recommended on realistic vehicle and restraint environment and advanced modeling strategies toward a full understanding of KAB efficacy. PMID- 29584492 TI - Differences in the protective capabilities of bicycle helmets in real-world and standard-specified impact scenarios. AB - OBJECTIVE: The purpose of this study was to investigate relative differences in impact attenuation capabilities of bicycle helmets under real-world impact conditions and safety standard-specified conditions using a standard rig. METHODS: A Consumer Product Safety Commission (CPSC) test rig was used to impact 10 helmet models of varied design. Impact configurations included 2 locations and 2 velocities. A frontal rim location (inferior to the standard-defined test area) and a temporal location were selected to reflect common cyclist impacts. An impact velocity of 3.4 m/s, an average normal impact velocity in cyclist accidents, was selected, as well as the CPSC standard velocity of 6.2 m/s. Four samples per helmet model were subjected to each of the 4 impact configurations once (randomized test order per sample), resulting in 160 drop tests. Peak linear acceleration (PLA) and head injury criterion (HIC)-based Abbreviated Injury Scale (AIS) >= 4 brain injury risk were determined and compared across helmets and impact configurations using analysis of variance. Other impact characteristics such as duration, effective liner stiffness, and energy dissipated were also calculated from acceleration data. RESULTS: Helmet performance varied significantly between models. PLA ranged from 78 to 169 g at 3.4 m/s (0-2% AIS >= 4 brain injury risk) and 165-432 g (10-100% risk) at 6.2 m/s. Temporal impacts resulted in higher PLAs than frontal impacts, likely due to increased effective liner stiffness. However, 2 helmets exceeded the CPSC pass-fail threshold (300 g) at the frontal rim location, producing >70% risk. Force-displacement curves suggest that bottoming-out occurred in these impacts. Aside from bottoming-out cases, helmets that performed worse in one impact configuration tended to perform worse in others, with non-road-style helmets among the worst. CONCLUSIONS: The 10 bicycle helmets tested produced considerable differences in their protective capabilities under both real-world and standard-specified conditions on the CPSC rig. Risk of severe brain injury varied widely between helmets at the standard impact velocity, whereas the common, lower severity impacts produced PLAs associated with concussion. Helmets of a nonroad style generally performed worse across configuration. The temporal location produced higher risks for most helmets, although some helmets were found to offer inadequate protection at the helmet rim. Because this is a commonly impacted location in cyclist accidents, there may be benefit to expanding the testable area in standards to include the rim. Results from this study demonstrate the value in testing nonstandard conditions and can be used to inform standards testing and helmet design. PMID- 29584494 TI - Frontal and oblique crash tests of HIII 6-year-old child ATD using real-world, observed child passenger postures. AB - OBJECTIVE: The aim of this study was to evaluate the consequences of frontal and oblique crashes when positioning a Hybrid III (HIII) 6-year-old child anthropometric test device (ATD) using observed child passenger postures from a naturalistic driving study (NDS). METHODS: Five positions for booster-seated children aged 4-7 years were selected, including one reference position according to the FMVSS 213 ATD seating protocol and 4 based on real-world observed child passenger postures from an NDS including 2 user positions with forward tilting torso and 2 that combined both forward and lateral inboard tilting of the torso. Seventeen sled tests were conducted in a mid-sized vehicle body at 64 km/h (European New Car Assessment Programme [Euro NCAP] Offset Deformable Barrier [ODB] pulse), in full frontal and oblique (15 degrees ) crash directions. The rear-seated HIII 6-year-old child ATD was restrained on a high-back booster seat. In 10 tests, the booster seat was also attached with a top tether. In the oblique tests, the ATD was positioned on the far side. Three camera views and ATD responses (head, neck, and chest) were analyzed. RESULTS: The shoulder belt slipped off the shoulder in all ATD positions in the oblique test configuration. In full frontal tests, the shoulder belt stayed on the shoulder in 3 out of 9 tests. Head acceleration and neck tension were decreased in the forward leaning positions; however, the total head excursion increased up to 210 mm compared to te reference position, due to belt slip-off and initial forward leaning position. CONCLUSIONS: These results suggest that real-world child passenger postures may contribute to shoulder belt slip-off and increased head excursion, thus increasing the risk of head injury. Restraint system development needs to include a wider range of sitting postures that children may choose, in addition to the specified postures of ATDs in seating test protocols, to ensure robust performance across diverse use cases. In addition, these tests revealed that the child ATD is limited in its ability to mimic real-world child passenger postures. There is a need to develop child human body models that may offer greater flexibility for these types of crash evaluations. PMID- 29584493 TI - Numerical investigation of driver lower extremity injuries in finite element frontal crash reconstruction. AB - OBJECTIVE: Lower extremity injuries are the most frequent Abbreviated Injury Scale (AIS) 2 injury for drivers in frontal crashes. The objective was to reconstruct 11 real-world motor vehicle crashes (2 with AIS 2+ distal lower extremity injury and 9 without lower extremity injury) and to analyze the vehicle parameters and driver attributes that affect injury risk. METHODS: Eleven frontal crashes were reconstructed with a finite element simplified vehicle model (SVM) using a semi-automated optimization method. The SVM was tuned to each corresponding vehicle and the Total HUman Model for Safety (THUMS) Ver 4.01 was scaled and positioned in a baseline configuration to mimic the documented precrash driver posture. The event data recorder crash pulse was applied as the boundary condition for each case. Additionally, for the 2 cases with lower extremity injury, 120 simulations to quantify the uncertainty and response variation were performed varying the following parameters using a Latin hypercube design of experiment (DOE): seat track position, seatback angle, steering column angle, steering column position, and D-ring height. Injury metrics implemented within THUMS were calculated from the femur, tibia, and ankle and cross-compared among the 11 baseline cases using tibia index and multiple injury risk functions. Kinetic and kinematic data from the 120-simulation DOE were analyzed and fit to regression models to examine any causal relationship between occupant positioning and lower extremity injury risk. RESULTS: Of the 11 real-world crashes, both cases with lower extremity injuries resulted in elevated tibia axial forces and resultant bending moments, compared to the 9 cases without lower extremity injury. The average tibia index of the 2 cases with distal lower extremity injury (left: 1.79; right: 1.19) was higher than that in the 9 cases without lower extremity injury (left: 1.16, P =.024; right: 0.82, P =.024). An increased risk of AIS 2+ tibia shaft (33.6%), distal tibia and hindfoot (20.0%), as well as ankle malleolar (14.5%) fracture was also observed for the injured compared to the noninjured cases. Rearward seat track position, reclined seat back angle, and reduced seat height were correlated with elevated tibia axial force and increased tibia index, imposing additional lower extremity injury risk. CONCLUSIONS: This study provides a computational framework for assessing lower extremity injuries and elucidates the effect of precrash driver posture on lower extremity injury risk while accounting for vehicle parameters and driver attributes. Results from the study aid in the evaluation of real-world injury data, the understanding of factors contributing to injury risk, and the prevention of lower extremity injuries. PMID- 29584495 TI - Using naturalistic driving data to better understand the driving exposure and patterns of older drivers. AB - OBJECTIVE: The aging of the population in the United States and elsewhere has brought increasing attention to the issue of safe driving and mobility among older adults. The overall objective of this research was to use naturalistic data collection to better understand driving exposure and driving patterns, 2 important contributors to crash risk. METHODS: Data came from a study conducted at the University of Michigan Transportation Research Institute as part of the Integrated Vehicle-Based Safety System (IVBSS) program. A total of 108 randomly sampled drivers took part, with the sample stratified by age and sex. The age groups examined were 20 to 30 (younger), 40 to 50 (middle-aged), and 60 to 70 years old (older). Sixteen late-model Honda Accords were used as research vehicles and were driven by participants as their personal vehicles over the study period. Roughly the first 2 weeks of vehicle use comprised the baseline driving period, during which the IVBSS technologies were turned off (i.e., no warnings were presented to the drivers) but all onboard data were collected. For this article, only data from the baseline period were analyzed to limit any confounding effects that the safety technology may have had on driving behavior. RESULTS: Results indicated that when looking at age independent of sex, older drivers (age 60-70) took fewer trips, drove fewer minutes, were less likely to drive at night, and had fewer high decelerations and speeding events than the youngest age group (20-30). They were also less likely to drive during peak morning traffic and on high-speed roads than their middle-age counterparts (40 50). Across all age groups, there were few differences by sex, with the exception that females drove fewer miles and fewer minutes and had fewer high decelerations than males. When both age and sex were taken into account, it was often the group of females age 60-70 that appeared to account for many of the age and sex differences found in driving exposure and patterns. CONCLUSIONS: Future research in this area would benefit from larger scale and longitudinal study designs so that changes in driving exposure and patterns over time among large samples of drivers could be examined. PMID- 29584496 TI - Evaluating drugged driving: Effects of exemplar pain and anxiety medications. AB - OBJECTIVE: Distracted and drug-influenced driving presents a major risk for traffic safety morbidity and mortality. As part of an ongoing research program, we examined the effects of a commonly prescribed combination of medications for pain relief: alprazolam, a benzodiazepine, and a hydrocodone preparation, a combination opiate and acetaminophen, on a simulated driving protocol. METHODS: Utilizing a within-subjects design, we recruited 8 healthy experienced drivers without major physical and psychological histories. Using a double-blind, placebo controlled crossover design, we administered placebo, alprazolam alone, hydrocodone/acetaminophen, and the combination of the 2 drugs in a standardized simulated driving protocol. Measures of lateral and longitudinal control were collected and the data were reduced and statically analyzed. RESULTS: The study observed clear detrimental effects of alprazolam on driving measures of lateral control and longitudinal control. Driving appeared to more aberrant at higher speeds and in rural scenarios. There were no statistical differences between hydrocodone and placebo. A measure of sedation showed that subjects rated alprazolam as more sedating than both hydrocodone and placebo. CONCLUSIONS: The findings suggest that impairing effects of this commonly prescribed combination of pharmacologic agents impact simulated driving performance. Negative changes in driving performance included measures of lateral and longitudinal control, although the deleterious effects on lateral control measures such as standard deviation of lane position (SDLP) were larger and more robust. Although the number of subjects was small, thus making it more difficult to draw conclusions on the narcotic effects, these results suggest that in this combination of central nervous system (CNS)-active drugs the benzodiazepine alprazolam accounted for the majority of impairing drug effects. The effect sizes associated with the hydrocodone preparation ranged from very small to medium. These results have potential implications for prescribing physicians and dispensing pharmacists, traffic safety experts, law enforcement officers, and patients themselves. PMID- 29584497 TI - Initial analysis of archived non-human primate frontal and rear impact data from the biodynamics data resource. AB - OBJECTIVE: The research objective was to conduct an initial analysis of non-human primate (NHP) data from frontal and rear impact events archived in the Biodynamics Data Resource (BDR) records of the Naval Biodynamics Laboratory (NBDL). These rare data, collected between 1973 and 1989, will inform the safety community of upper-end tolerance limits of NHP and may be related to severe crash scenarios. METHODS: Data from frontal and rear acceleration tests to 93 macaque NHP were examined. Each NHP was fully torso restrained, whereas the head-neck complex was unrestrained. Each NHP underwent between 1 and 21 total runs; 2 total runs was most common-a low-level run and then a high-level run. Following each impact exposure, the NHP was evaluated using a series of medical examinations. Now part of the legacy collection in the BDR, these evaluations were used to assess NHP exposures to be in one of 3 categories: noninjurious, injurious, or fatal. Using reported peak sled acceleration values, data were amenable to survival analysis statistical methodology to derive injury probability curves (IPCs). IPCs were derived for injury and fatality outcomes. RESULTS: Fatal injuries for both frontal and rear impacts were mostly at the cranio-vertebral junction. In addition to hemorrhage, fatal frontal and rear impact tests both produced predominantly atlanto-occipital dislocations, with and without spinal cord transection. After exclusions, IPCs were derived for frontal and rear impact for both (1) fatal outcome and (2) injurious outcome (any injury including fatal injury). For frontal impact, 53 NHP qualified with 5, 25, and 50% risk for fatality at 89, 105, and 114 peak sled Gs, respectively, and for injurious outcome at 70, 92, and 106 Gs, respectively. For rear impact, 34 NHP qualified with 5, 25, and 50% risk for fatality at 96, 122, 138 peak sled Gs, respectively, and for injurious outcome at 75, 99, and 115 Gs, respectively. CONCLUSIONS: The majority of injuries were at the cranio-vertebral junction, indicating that the inertial head mass caused a tensile loading mechanism to the cervical spine. These data may be used in conjunction with finite element modeling to estimate risks to the human population. The most direct application in the automotive environment could be to the well-restrained child. The Nij neck injury criteria, currently based on data from piglet studies, could also benefit because the NHP is a more accurate human surrogate. These types of tests are likely to never be repeated and will form an upper bound of tolerance information valuable to safety system designers. PMID- 29584498 TI - The influence of child restraint lower attachment method on protection offered by forward facing child restraint systems in oblique loading conditions. AB - OBJECTIVE: The research objective was to quantify the influence of child restraint lower attachment method on head kinematics, head impact potential, and head, neck, and thorax injury metrics for a child occupant secured in a forward facing child restraint system (FFCRS) in oblique side impacts. METHODS: Fifteen sled tests were conducted with a Q3s seated in an FFCRS secured to the center position on a production small SUV bench seat. Three lower attachment methods were evaluated: rigid ISOFIX, a flexible single loop lower anchors and tethers for children (LATCH) webbing routed through the vehicle belt path of the FFCRS, and dual flexible LATCH webbing attachments on either side of the FFCRS. All were tested with and without a tether with one repeat test in each test condition. The same model FFCRS was used for all tests; only the attachment method varied. The vehicle bench seat was fixed on the sled carriage at 80 degrees (from full frontal). The input pulse was the proposed FMVSS 213 side impact pulse scaled to a 35 km/h delta-v. Two-way analysis of variance (ANOVA) was used to evaluate the effect of lower attachment and tether use on 3 outcome metrics: lateral head excursion, neck tension, and neck lateral bending. Data included anthropomorphic test dummy (ATD) head excursions, head linear accelerations and angular velocities, neck loads and moments, thoracic accelerations, lateral chest deflections, lower anchor loads, and tether webbing loads. ATD head kinematics were collected from 3-dimensional motion capture cameras. RESULTS: Results demonstrated a reduction in injury measures with the rigid ISOFIX and dual webbing attachment compared to the single webbing attachment with decreased lateral head excursions (331, 356, and 441 mm for the rigid ISOFIX, dual webbing, and single webbing systems, respectively, P <.0001), neck tension (1.4, 1.6, and 2.2 kN, P <.01), and neck lateral bending (31.8, 38.7, and 38.0 Nm, P =.002). The tether had a greater influence on lateral head excursion for the FFCRS with flexible webbing attachments than those with the rigid attachment, with the tether forces being highest with the single webbing attachment. Lateral head excursions were significantly lower and lateral neck bending moments were significantly higher with tether use (P <.0001) across all lower attachments. The effect of tether on neck tension was mixed, only showing an increased effect with the rigid ISOFIX system. CONCLUSION: The CRS lower attachment system influenced occupant kinetics. The results indicate that CRS attached to the vehicle via rigid and dual webbing systems exhibit improved kinematics by reducing the rotation and tipping seen with the single webbing attachment. This leads to reduced lateral head excursions and neck tension values. The advantages of the tether in reducing lateral head excursion in side impacts are most pronounced with the flexible webbing attachments. With tether use low in the United States, a dual webbing type FFCRS attachment system may be a better attachment method than single webbing and provide a simpler engineering solution than rigid ISOFIX attachment. PMID- 29584499 TI - Burden of road traffic injuries related to delays in implementing safety belt laws in low- and lower-middle-income countries. AB - OBJECTIVE: Delayed implementation of effective road safety policies must be considered when quantifying the avoidable part of the fatal and nonfatal injuries burden. We sought to assess the avoidable part of disability-adjusted life years (DALYs) lost due to road traffic injuries related to delays in implementing road safety laws in low- and lower-middle-income countries. METHODS: We chose one country for each of the regions of the World Health Organization (WHO) and World Bank (WB) country income levels. We used freely available data sets (WHO, International Traffic Safety Data and Analysis Group, the WB). Delays in implementation were calculated until 2013, from the year mandatory use of safety belts by motor vehicle front seat occupants was first introduced worldwide. We used life expectancy tables and age groups as social values in the DALY calculation model. From the estimated total burden, avoidable DALYs were calculated using estimates of the effectiveness of seat belt laws on fatal and nonfatal injuries combined, as extracted from published international reviews of evidence. RESULTS: From the reference year 1972, implementation delays varied from 27 years (Uzbekistan) to 41 years in Bolivia (no seat belt law as of 2013). During delays, total absolute numbers of DALYs lost due to road traffic injuries reached 8,462,099 in Nigeria, 7,203,570 in Morocco, 4,695,500 in Uzbekistan, 3,866,391 in Cambodia, 3,253,359 in Bolivia, and 3,128,721 in Sri Lanka. Using effectiveness estimates ranging from 3 to 20% reduction, the avoidable burden of road traffic injuries for car occupants was highest in Uzbekistan (avoidable part from 1.2 to 10.4%) and in Morocco (avoidable part from 1.5 to 12.3%). In countries where users of public transport and pedestrians were the most affected by the burden, the avoidable parts ranged from 0.5 to 4.4% (Nigeria) and from 0.5 to 3.4% (Bolivia). Burden of road traffic injuries mostly affected motorcyclists in Sri Lanka and Cambodia where the avoidable parts were less than 2% in both countries. In all selected countries, burden of traffic injuries mostly affected men (about 80%) as well as young people (15-34 years). CONCLUSIONS: Despite limited data availability in low- and middle-income countries, the avoidable part of the burden related to delayed intervention is measurable. These results can be used to convince countries to avoid delaying the provision of better protection to road users. PMID- 29584500 TI - Comparison of three-point belt fit between humans and ATDs in rear seats. AB - OBJECTIVE: The anthropomorphic test devices (ATDs) in the Hybrid III family are widely used as human surrogates to test the crash performance of vehicles. A previous study demonstrated that passenger belt fit in rear seats was affected by high body mass index (BMI) and to a lesser extent by increased age. Specifically, the lap belt was worn higher and more forward as BMI and age increased. The objective of this study was to compare passenger belt fit to the belt fit achieved when installing the small female and midsize male Hybrid III adult ATDs using standard procedures. METHODS: The ATDs were installed using standardized procedures in the same conditions previously used with volunteers. Belt fit was measured using methods analogous to those used for the volunteers. Comparative human belt fit values were obtained by using regression analysis with the volunteer data to calculate the mean expected belt fit for people the same size as the ATDs. RESULTS: For the small female ATD, the upper edge of the lap belt was on average 59 mm forward and 11 mm above the anterior-superior iliac spine (ASIS) landmark on the ATD pelvis bone. In contrast, the belt position for similar size passengers was 17 mm forward and 22 mm above the ASIS. For the midsize male ATD, the belt was 34 mm forward and 10 mm above the ASIS. For similar size passengers, the position was 38 mm forward and 44 mm above the ASIS. For context, the belt width in this study was 38 mm. DISCUSSION: The results suggest that the lap belt fit obtained by ATDs is more idealized but more repeatable compared to that achieved by similar size passengers. Future standardization efforts should consider investigating whether new belt positioning procedures with ATDs may improve the biofidelity of ATD response. PMID- 29584501 TI - Quality of head injury coding from autopsy reports with AIS (c) 2005 update 2008. AB - : ABSTACT Objective: Coding injuries from autopsy reports of traffic accident victims according to Abbreviated Injury Scale AIS (c) 2005 update 2008 [1] is quite time consuming. The suspicion arose, that many issues leading to discussion between coder and control reader were based on information required by the AIS that was not documented in the autopsy reports. METHODS: To quantify this suspicion, we introduced an AIS-detail-indicator (AIS-DI). To each injury in the AIS Codebook one letter from A to N was assigned indicating the level of detail. Rules were formulated to receive repeatable assignments. This scheme was applied to a selection of 149 multiply injured traffic fatalities. The frequencies of "not A" codes were calculated for each body region and it was analysed, why the most detailed level A had not been coded. As a first finding, the results of the head region are presented. RESULTS: 747 AIS head injury codes were found in 137 traffic fatalities, and 60% of these injuries were coded with an AIS-DI of level A. There are three different explanations for codes of AIS-DI "not A": Group 1 "Missing information in autopsy report" (5%), Group 2 "Clinical data required by AIS" (20%), and Group 3 "AIS system determined" (15%). Groups 1 and 2 show consequences for the ISS in 25 cases. Other body regions might perform differently. CONCLUSIONS: The AIS-DI can indicate the quality of the underlying data basis and, depending on the aims of different AIS users it can be a helpful tool for quality checks. PMID- 29584502 TI - An insight of World Health Organization (WHO) accident database by cluster analysis with self-organizing map (SOM). AB - OBJECTIVE: Road crashes are increasing every year in low- and middle-income countries compared to high-income countries, which show decreasing trends. One theory may be because of differences in enforcement of laws, vehicle safety, road standards, and many other factors. A detailed review was made of 5 death trends (total number of deaths/100,000 population and percentages of 4-wheeler, pedestrian, motorized 2/3-wheeler, bicyclist) and the underlying patterns in different countries and regions across the world. This review was done to understand the main reasons for the variances to focus on efficient improvement strategies related to future vehicle and road safety issues. METHODS: A self organizing map (SOM) technique is used to map the nonlinear relationships among different attributes. Overall, 176 countries with 44 attributes were considered from the World Health Organization's (WHO) Global Status Report on Road Traffic Crashes database. Of the 44 attributes, 5 related to accident deaths were considered as response attributes. RESULTS: Very distinct and unique cause-effect patterns for 3 clusters were observed from SOM results. High-income countries were found to have a lower total number of deaths/100,000 population. One theory espouses that this was due to those countries maintaining high vehicle standards and policies, whereas it was quite a different situation for low-income countries. Even though helmet laws were available in Association of South East Asian Nations + 6 (ASEAN + 6) countries, the percentage of 2/3-wheeler deaths may be higher due a lack of enforcement of those laws. Percentage of deaths involving 4-wheeler vehicles was higher in certain countries in the Persian Gulf, the United States, Australia, and New Zealand. This may be due to the fact that these countries have a number of rural areas where drivers drive at highway speeds versus some lower income countries with more urban areas where drivers operate vehicles at slower speeds. Countries with a lack of laws protecting bicyclists saw higher death percentages among bicyclists. The percentage of bicyclist deaths was also higher in areas with no helmet requirement and no investment in infrastructure improvements. The percentage of pedestrian deaths was high when there was no policy to separate road users, especially in low-income African countries. Deaths can be reduced by enforcement of laws and practicing good safety standards related to road traffic. CONCLUSIONS: Future vehicle and road safety strategies should consider using advanced statistical tools like SOM to advance safety. Based on a triple-layer (vehicle, infrastructure, and society) safety approach, strict regulations and enforcement are effective measures to reduce fatalities in low- and middle-income countries. On the other hand, introduction of more advanced vehicle technologies will be useful in countries with high gross national incomes (GNIs). Hence, a proper balance of different countermeasures based on economic zones could be effective to reduce total world traffic casualties. PMID- 29584503 TI - Influence of morphological variations on cervical spine segmental responses from inertial loading. AB - OBJECTIVES: The objective of this study was to investigate the influence of morphological variations in osteoligamentous lower cervical spinal segment responses under postero-anterior inertial loading. METHODS: A parametric finite element model of the C5-C6 spinal segment was used to generate models. Variations in the vertebral body and facet depth (anteroposterior), posterior process length, intervertebral disc height, facet articular process height and slope, segment orientation ranging from lordotic to straight, and segment size were parameterized. These variations included male-female differences. A Latin hypercube sampling method was used to select parameter values for model generation. Forces and moments associated with the inertial loading were applied to the generated model segments. The 7 parameters were grouped as local or global depending on the number of spinal components involved in the shape variation. Four output responses representing overall segmental and soft tissue responses were analyzed for each model variation: response angle of the segment, anterior longitudinal ligament stretch, anterior capsular ligament stretch, and facet joint compression in the posterior region. Pearson's correlation coefficient was used to compute the correlations of these output responses with morphological variations. RESULTS: Fifty models were generated from the parameterized model using a Latin hypercube sampling technique. Variation in response angle among the models was 4 degrees and was most influenced by change in the combined dimension of vertebral body and facet depth, followed by size of the segment. The maximum anterior longitudinal ligament stretch varied between 0.1 and 0.3 and was strongly influenced by the change in the segment orientation. The anterior facet joint region sustained tension, whereas the posterior region sustained compression. For the anterior capsular ligament stretch, the most influential global variation was segment orientation, whereas the most influential local variations were the facet height and facet angle parameters. In the case of posterior facet joint compression, segment orientation was again most influential, whereas among the local variations, the facet angle had the most influence. CONCLUSION: Shape variations in the intervertebral disc influenced segmental rotation and ligament responses; however, the influence of shape variations in the facet joint was confined to capsular ligament responses. Response angle was most influenced by the vertebral body depth variations, explaining greater segmental rotations in female spines. Straighter spine segments sustained greater posterior facet joint compression, which may offer an explanation for the higher incidence of whiplash-associated disorders among females, who exhibit a straighter cervical spine. The anterior longitudinal ligament stretch was also greater in straighter segments. These findings indicate that the morphological features specific to the anatomy of the female cervical spine may predispose it to injury under inertial loading. PMID- 29584504 TI - Top tether effectiveness during side impacts. AB - OBJECTIVE: Few studies have looked at the effectiveness of the top tether during side impacts. In these studies, limited anthropomorphic test device (ATD) data were collected and/or few side impact scenarios were observed. The goal of this study was to further understand the effects of the top tether on ATD responses and child restraint system (CRS) kinematics during various side impact conditions. METHODS: A series of high-speed near-side and far-side sled tests were performed using the FMVSS213 side impact sled buck and Q3s ATD. Tests were performed at both 10 degrees and 30 degrees impacts with respect to the pure lateral direction. Two child restraints, CRS A and CRS B, were attached to the bench using flexible lower anchors. Each test scenario was performed with the presence and absence of a top tether. Instrumentation recorded Q3s responses and CRS kinematics, and the identical test scenarios with and without a top tether attachment were compared. RESULTS: For the far-side lateral (10 degrees ) and oblique (30 degrees ) impacts, top tether attachment increased resultant head accelerations by 8-38% and head injury criterion (HIC15) values by 20-140%. However, the top tether was effective in reducing lateral head excursion by 5 25%. For near-side impacts, the top tether resulted in less than 10% increases in both resultant head acceleration and HIC15 in the lateral impact direction. For near-side oblique impacts, the top tether increased HIC15 by 17.3% for CRS A and decreased it by 19.5% for CRS B. However, the injury values determined from both impact conditions were below current injury assessment reference values (IARVs). Additionally, the top tether proved beneficial in preventing forward and lateral CRS rotations. CONCLUSIONS: The results show that the effects of the top tether on Q3s responses were dependent on impact type, impact angle, and CRS. Tether attachments that increased head accelerations and HIC15 values were generally counterbalanced by a reduction in head excursion and CRS rotation compared to nontethered scenarios. PMID- 29584505 TI - A preliminary study of human model head and neck response to frontal loading in nontraditional occupant seating configurations. AB - OBJECTIVE: Computational human body models (HBMs) are nominally omnidirectional surrogates given their structural basis in human anatomy. As a result, such models are well suited for studies related to occupant safety in anticipated highly automated vehicles (HAVs). We utilize a well-validated HBM to study the head and neck kinematics in simulations of nontraditional occupant seating configurations. METHODS: The GHBMC M50-O v. 4.4 HBM was gravity settled into a generic seat buck and situated in a seated posture. The model was simulated in angular increments of 15 degrees clockwise from forward facing to rear facing. A pulse of 17.0 kph (NASS median) was used in each to simulate a frontal impact for each of the 13 seating configurations. Belt anchor points were rotated with the seat; the airbag was appropriately powered based on delta-V, and was not used in rear-facing orientations. Neck forces and moments were calculated. RESULTS: The 30-degree oblique case was found to result in the maximum neck load and sagittal moment, and thus Neck Injury Criteria (NIJ). Neck loads were minimized in the rear facing condition. The moments and loads, however, were greatest in the lateral seating configuration for these frontal crash simulations. CONCLUSIONS: In a recent policy statement on HAVs, the NHTSA indicated that vehicle manufacturers will be expected to provide countermeasures that will fully protect occupants given any planned seating or interior configurations. Furthermore, the agency indicated that virtual tests using human models could be used to demonstrate such efficacy. While the results presented are only appropriate for comparison within this study, they do indicate that human models provide reasonable biomechanical data for nontraditional occupant seating arrangements. PMID- 29584506 TI - AIS scores in spine and spinal cord trauma: Epidemiological considerations. AB - BACKGROUND: The Abbreviated Injury Scale (AIS) is an internationally accepted coding system created by the Association for the Advancement of Automotive Medicine, utilized to code traumatic injuries as a function of severity, the latter often defined as mortality risk. Periodic reassessment of that risk is prudent, in light of advances in health care and relationship of nonanatomic factors to death. OBJECTIVE: The objective of this study was to reevaluate the risk of death associated with spine fractures with and without neurologic deficit, age factors associated with it, and the impact of hospital coding on the accuracy of these efforts. METHODS: Medical records and imaging of patients treated at a level 1 trauma center from 2014 through 2016 with discharge International Classification of Diseases, 10th revision (ICD-10) diagnoses of spinal trauma and spinal cord injury (SCI) were reviewed. Data were collected on demographics, complications, neurologic status, and outcomes. RESULTS: Three hundred seventy patients met the criteria for inclusion in this effort. Errors in ICD-10 discharge codes were seen in 45% of the cases, both false positive and negative. One hundred thirty-four patients, with a mean age of 45, were admitted with neurologic deficit. There were 8 SCI-related deaths; 2 were postoperative out of 110 undergoing surgical treatment. All deaths in this group were in patients with upper level SCI, with a mean age of 68. Ten patients had spontaneous neurologic improvement within 24 h. One hundred nineteen patients without deficit had AIS 2 scored fractures; there was one postoperative death out of 47 patients undergoing surgical treatment. One hundred seventeen patients without deficit suffered AIS 3 fractures; 66 underwent surgery without any deaths. There was one nonoperative death. Age and high quadriplegia were the only factors associated with mortality. CONCLUSIONS: Mortality risk in patients with deficit was associated more with age at injury than extent of anatomic injury. Spine trauma without neurologic deficit is benign in younger populations and AIS scores could be age adjusted. Mortality risk is higher in high cervical injuries with neurologic deficit and in the elderly. An incidental finding is that demographic studies based solely on discharge ICD coding may contain errors and should be considered critically. PMID- 29584507 TI - Trunk muscle recruitment patterns in simulated precrash events. AB - OBJECTIVES: To quantify trunk muscle activation levels during whole body accelerations that simulate precrash events in multiple directions and to identify recruitment patterns for the development of active human body models. METHODS: Four subjects (1 female, 3 males) were accelerated at 0.55 g (net Deltav = 4.0 m/s) in 8 directions while seated on a sled-mounted car seat to simulate a precrash pulse. Electromyographic (EMG) activity in 4 trunk muscles was measured using wire electrodes inserted into the left rectus abdominis, internal oblique, iliocostalis, and multifidus muscles at the L2-L3 level. Muscle activity evoked by the perturbations was normalized by each muscle's isometric maximum voluntary contraction (MVC) activity. Spatial tuning curves were plotted at 150, 300, and 600 ms after acceleration onset. RESULTS: EMG activity remained below 40% MVC for the three time points for most directions. At the 150- and 300 ms time points, the highest EMG amplitudes were observed during perturbations to the left (-90 degrees ) and left rearward (-135 degrees ). EMG activity diminished by 600 ms for the anterior muscles, but not for the posterior muscles. CONCLUSIONS: These preliminary results suggest that trunk muscle activity may be directionally tuned at the acceleration level tested here. Although data from more subjects are needed, these preliminary data support the development of modeled trunk muscle recruitment strategies in active human body models that predict occupant responses in precrash scenarios. PMID- 29584508 TI - Understanding fatal older road user crash circumstances and risk factors. AB - OBJECTIVE: This study used medicolegal data to investigate fatal older road user (ORU) crash circumstances and risk factors relating to four key components of the Safe System approach (e.g., roads and roadsides, vehicles, road users, and speeds) to identify areas of priority for targeted prevention activity. METHODS: The Coroners Court of Victoria's Surveillance Database was searched to identify coronial records with at least one deceased ORU in the state of Victoria, Australia, for 2013-2014. Information relating to the ORU, crash characteristics and circumstances, and risk factors was extracted and analyzed. RESULTS: The average rate of fatal ORU crashes per 100,000 population was 8.1 (95% confidence interval [CI] 6.0-10.2), which was more than double the average rate of fatal middle-aged road user crashes (3.6, 95% CI 2.5-4.6). There was a significant relationship between age group and deceased road user type (chi2(15, N = 226) = 3.56, p < 0.001). The proportion of deceased drivers decreased with age, whereas the proportion of deceased pedestrians increased with age. The majority of fatal ORU crashes involved a counterpart (another vehicle: 59.4%; fixed/stationary object: 25.4%), and occurred "on road" (87.0%), on roads that were paved (94.2%), dry (74.2%), and had light traffic volume (38.3%). Road user error was identified by the police and/or coroner for the majority of fatal ORU crashes (57.9%), with a significant proportion of deceased ORU deemed to have "misjudged" (40.9%) or "failed to yield" (37.9%). CONCLUSIONS: Road user error was the most significant risk factor identified in fatal ORU crashes, which suggests that there is a limited capacity of the Victorian road system to fully accommodate road user errors. Initiatives related to safer roads and roadsides, vehicles, and speed zones, as well as behavioral approaches, are key areas of priority for targeted activity to prevent fatal older road user crashes in the future. PMID- 29584509 TI - Improvement of injury severity prediction (ISP) of AACN during on-site triage using vehicle deformation pattern for car-to-car (C2C) side impacts. AB - OBJECTIVE: The Advanced Automatic Crash Notification (AACN) system needs to predict injury accurately, to provide appropriate treatment for seriously injured occupants involved in motor vehicle crashes. This study investigates the possibility of improving the accuracy of the AACN system, using vehicle deformation parameters in car-to-car (C2C) side impacts. METHODS: This study was based on car-to-car (C2C) crash data from NASS-CDS, CY 2004-2014. Variables from Kononen's algorithm (published in 2011) were used to build a "base model" for this study. Two additional variables, intrusion magnitude and max deformation location, are added to Kononen's algorithm variables (age, belt usage, number of events, and delta-v) to build a "proposed model." This proposed model operates in two stages: In the first stage, the AACN system uses Kononen's variables and predicts injury severity, based on which emergency medical services (EMS) is dispatched; in the second stage, the EMS team conveys deformation-related information, for accurate prediction of serious injury. RESULTS: Logistic regression analysis reveals that the vehicle deformation location and intrusion magnitude are significant parameters in predicting the level of injury. The percentage of serious injury decreases as the deformation location shifts away from the driver sitting position. The proposed model can improve the sensitivity (serious injury correctly predicted as serious) from 50% to 63%, and overall prediction accuracy increased from 83.5% to 85.9%. CONCLUSION: The proposed method can improve the accuracy of injury prediction in side-impact collisions. Similar opportunities exist for other crash modes also. PMID- 29584510 TI - Bioimpedance Vector Analysis of Elite, Subelite, and Low-Level Male Volleyball Players. AB - PURPOSE: To establish a specific player profile on body-composition parameters and to provide a data set of bioelectric impedances values for male volleyball players. METHODS: The study included 201 athletes (age 26.1 [5.4] y, height 191.9 [9.7] cm, weight 86.8 [10.8] kg) registered in the Italian volleyball divisions. The athletes were divided into 3 groups: The elite group comprised 75 players participating in the 1st (Super Lega) division, the subelite group included 65 athletes performing in the 2nd (Serie A2) division, and the low-level group included 61 players participating in the 3rd (Serie B) division. Bioelectric impedance, body weight, and height of the athletes were measured in the second half of the competitive season. In addition, bioelectrical impedance vector analysis was performed. RESULTS: The elite group showed a greater amount of fat free mass (FFM) and total body water (TBW) and a lower fat mass (FM) than the subelite group (P < .05). In addition, the elite players were taller and heavier and had a higher FFM, FM, TBW, and body cellular mass than the low-level athletes (P < .05). Finally, the mean impedance vectors of the elite group significantly differed from those measured in the normal population and in the other 2 groups (P < .05). CONCLUSIONS: This study provides an original data set of body composition and bioelectric impedance reference values of elite male volleyball players. The results might be useful for interpretation of individual bioimpedance vectors and for defining target regions for volleyball players. PMID- 29584511 TI - Micro-computed tomographic evaluation of the effect of the final apical size prepared by rotary nickel-titanium files on the removal efficacy of hard-tissue debris. AB - Objective This study was performed to compare the removal efficacy of hard-tissue debris in mandibular first molars prepared to various apical sizes. Methods The mesial root canals of 40 extracted mandibular first molars were prepared by rotary nickel-titanium files to an apical size of #25/0.04 (Group #2504), #30/0.04 (Group #3004), #35/0.04 (Group #3504), and #40/0.04 (Group #4004). Irrigation was performed with 5.25% NaOCl and 17% EDTA. Micro-computed tomography was used to scan the samples before and after root canal preparation. Remnant hard-tissue debris was identified, quantified, and visualized three-dimensionally using shape recognition and image superimposition analysis, and the debris was mapped to its location. Results After preparation, 11.67%+/-2.99% of the root canals contained hard-tissue debris in Group #2504, 8.00%+/-2.71% in Group #3004, 7.17%+/-2.88% in Group #3504, and 4.51%+/-1.61% in Group #4004. The amount of accumulated hard-tissue debris was significantly less in Group #4004 than in the other groups. However, there were no significant differences between Groups #3004 and #3504. Conclusions An increased final apical size resulted in significantly lower debris accumulation. However, no root canal in any group was completely free from hard-tissue debris, and debris was mostly found in the isthmus of the mesial root canals. PMID- 29584512 TI - Acute prevertebral abscess secondary to intradiscal oxygen-ozone chemonucleolysis for treatment of a cervical disc herniation. AB - Objective We herein present a case involving a prevertebral abscess complicated by a spinal epidural abscess (SEA) secondary to intradiscal oxygen-ozone chemonucleolysis for treatment of a cervical disc herniation. Methods A 67-year old woman with a history of intradiscal oxygen-ozone chemonucleolysis developed numbness and weakness in her right upper and bilateral lower extremities followed by urinary retention. Her symptoms did not respond to intravenous antibiotics alone. Magnetic resonance imaging of the cervical region revealed an extensive SEA anterior to the spinal cord, spinal cord myelopathy due to anterior compression by the lesion, and a prevertebral abscess extending from C2 to T1. She underwent surgical drainage and irrigation. Results The patient was successfully treated with surgical drainage and systemic antibiotic therapy without kyphosis. Streptococcus intermedius was detected within the abscess. All clinical symptoms except for the sensory deficit in the left leg were relieved. Conclusions The safety of intradiscal oxygen-ozone therapy requires further assessment. High-dose intravenous antibiotics should be initiated empirically at the earliest possible stage of prevertebral and epidural abscesses. Surgical drainage may be a rational treatment choice for patients with a prevertebral abscess complicated by an SEA and spinal cord myelopathy. PMID- 29584513 TI - Three-by-Three Basketball: Inertial Movement and Physiological Demands During Elite Games. AB - PURPOSE: To determine the demands of elite male and female 3 * 3 basketball games and compare these between various competition levels. METHODS: A total of 361 males and 208 females competing in the Under-18 World, Senior European, and World Championships and selected professional tournaments had game demands assessed by wearable technology (global positioning system, inertial measurement, heart rate) along with postgame blood lactate and perceived responses. Differences in the means were compared using magnitude-based inferences and reported with effect size and 90% confidence limits, along with the percentage difference (effect size; +/-90% confidence limits, %) of log-transformed data. RESULTS: PlayerLoadTM and PlayerLoad.min-1 during play was 127.5 (31.1) and 6.7 (1.5) for males and 128.5 (32.0) and 6.5 (1.4) for females, respectively, with small differences between junior, senior, and professional levels. There were small differences in accelerations >3.5 m.s-1 between competition levels up to 0.31; +/-0.20, 6.9% for males and 0.29; +/-0.19, 10.8% for females and for decelerations >3.5 m.s-1, 0.29; +/-0.19, 15.6% for males and 0.26; +/-0.19, 5.4% for females, with European Championships generally greater than other levels. Average game heart rate was 165 (18) and 164 (12) beats.min-1 for males and females, with no difference between levels. Average rating of perceived exertion was 5.7 (2.1) and 5.4 (2.0) for males and females. CONCLUSIONS: 3 * 3 basketball games require high-speed inertial movements within limited distance, creating a relatively high physiological response. Practitioners working with 3 * 3 players should endeavor to focus on the attributes that will improve these player characteristics for greater success. PMID- 29584514 TI - The Same Story or a Unique Novel? Within-Participant Principal-Component Analysis of Measures of Training Load in Professional Rugby Union Skills Training. AB - PURPOSE: To identify which combination metrics of external and internal training load (TL) capture similar or unique information for individual professional players during skills training in rugby union using principal-component (PC) analysis. METHODS: TL data were collected from 21 male professional rugby union players across a competitive season. This included PlayerLoadTM, total distance, and individualized high-speed distance (>61% maximal velocity; all external TL) obtained from a microtechnology device (OptimEye X4; Catapult Innovations, Melbourne, Australia) that was worn by each player and the session rating of perceived exertion (RPE) (internal TL). PC analysis was conducted on each individual to extract the underlying combinations of the 4 TL measures that best describe the total information (variance) provided by the measures. TL measures with PC loadings (PCL) above 0.7 were deemed to possess well-defined relationships with the extracted PC. RESULTS: The findings show that from the 4 TL measures, the majority of an individual's TL information (first PC: 55-70%) during skills training can be explained by session RPE (PCL: 0.72-0.95), total distance (PCL: 0.86-0.98), or PlayerLoad (PCL: 0.71-0.98). High-speed distance was the only variable to relate to the second PC (PCL: 0.72-1.00), which captured additional TL information (+19-28%). CONCLUSIONS: Findings suggest that practitioners could quantify the TL of rugby union skills training with one of PlayerLoad, total distance, or session RPE plus high-speed distance while limiting omitted information of the TL imposed during professional rugby union skills training. PMID- 29584515 TI - Track-structure simulations of energy deposition patterns to mitochondria and damage to their DNA. AB - PURPOSE: Mitochondria have been implicated in initiating and/or amplifying the biological effects of ionizing radiation not mediated via damage to nuclear DNA. To help elucidate the underlying mechanisms, energy deposition patterns to mitochondria and radiation damage to their DNA have been modelled. METHODS: Track structure simulations have been performed with PARTRAC biophysical tool for 60Co gamma-rays and 5 MeV alpha-particles. Energy deposition to the cell's mitochondria has been analyzed. A model of mitochondrial DNA reflecting experimental information on its structure has been developed and used to assess its radiation-induced damage. RESULTS: Energy deposition to mitochondria is highly inhomogeneous, especially at low doses. Although a dose-dependent fraction of mitochondria sees no energy deposition at all, the hit ones receive rather high amounts of energy. Nevertheless, only little damage to mitochondrial DNA occurs, even at large doses. CONCLUSION: Mitochondrial DNA does not represent a critical target for radiation effects. Likely, the key role of mitochondria in radiation-induced biological effects arises from the communication between mitochondria and/or with the nucleus. Through this signaling, initial modifications in a few heavily hit mitochondria seem to be amplified to a massive long-term effect manifested in the whole cell or even tissue. PMID- 29584516 TI - Effect of Intermittent Hypoxia Training for Dizziness: A Randomized Controlled Trial. AB - OBJECTIVE: To study the effect of intermittent hypoxia training (IHT) for dizziness. DESIGN: A single-blind, randomized controlled trial. All participants were recruited from a rehabilitation department in an acute university-affiliated hospital. INTERVENTION: Participants with dizziness were randomly assigned to two groups (IHT group and control group). The Dizziness Handicap Inventory (DHI), Activities-specific Balance Confidence Scale (ABC), Vertigo Visual Analog Scale (VVAS) were conducted at baseline, end of the 4th week. RESULTS: Among 52 subjects, eighteen males and thirty four females, ages from 35 to 62 years old (mean +/- SD = 46.9 +/- 7.93). Time length since onset ranged from 12 months to 34 months (20.2+/-7.15 months). DHI, ABC, VVAS scores and attack frequencies of dizziness were improved after IH training intervention in the end of 4th week. There were significant differences between IHT group and control group in DHI, ABC, VVAS scores and attack frequencies of dizziness in the end of 4th week (P<0.05). No adverse events occurred during the study. CONCLUSION: IHT could improve dizziness after intervention in end of 4th week. IHT could be the effective method for releasing dizziness. PMID- 29584517 TI - Electronic medical records and risk management in hospitals of Saudi Arabia. AB - OBJECTIVE: Electronic medical records systems and the associated risks have been well studied in developed countries; the same cannot be said for systems in developing countries. Previous research in Saudi Arabian health-care organizations has shown a low level of quality in hospital services due to ineffective risk management. The objective of this research is to apply the Systems Theoretic Accident Modelling and Processes (STAMP) risk management technique in Saudi Arabia and evaluate its implementation. PARTICIPANTS: The participating organization is a health-care organization in Saudi Arabia Methods: A two-phase case study was conducted. The first phase implemented the STAMP technique to identify and manage risks to the system. For the second phase, the STAMP technique was extended to include a checklist, to increase STAMP's capability to mitigate risks, and the process reapplied. RESULTS AND CONCLUSION: The results demonstrated that the inclusion of the STAMP Checklist reduced errors and prevented system failures compared to regular STAMP. PMID- 29584518 TI - Planned Load Reduction Versus Fixed Load: A Strategy to Reduce the Perception of Effort With Similar Improvements in Hypertrophy and Strength. AB - PURPOSE: To compare muscle thickness and 10-repetition maximum (10RM) between no load reduction and load reductions during 16 wk of resistance training. METHODS: A total of 21 moderately trained men (age 23.2 [4.2] y, body mass 75.1 [7.6] kg, height 175 [4] cm) were randomized into 1 of 3 exercise groups: control (CON, n = 7), all sets with 10RM load; 5% load reduction (RED 5, n = 7); and 10% load reduction (RED 10, n = 7) for set 2 and set 3. The resistance training program consisted of completing 3 sets each of biceps and Scott curls, performed to volitional fatigue 3 d.wk-1. RESULTS: Volume load lifted over the 16 wk was similar among groups (CON, 38,495 [4397] kg; RED 5, 37,388 [3684] kg; RED 10, 42,634 [6733] kg; P = .094). Muscle thickness increased in all groups (P < .001), with no differences noted among groups (P = .976). Biceps-curl and Scott-curl 10RM increased in all groups (P < .001), with no differences noted among groups (Scott curl P = .238; biceps curl P = .401). Rating of perceived exertion (RPE) was significantly lower for RED 10 (6.8 [0.1]) than for CON (7.0 [0.1]; P < .001) or RED 5 (7.1 [0.1]; P = .001) for the Scott curl. RPE was significantly lower (P = .001) for the biceps curl in RED 10 (6.8 [0.3]) than in CON (7.3 [0.9]), with neither group different from RED 5 (7.0 [0.1]). CONCLUSIONS: Load reduction did not yield a difference in hypertrophy or 10RM as compared with CON. However, RED 10 induced a significantly lower RPE. Thus, load reduction may be a beneficial strategy to reduce the perception of effort during training while achieving similar improvements in hypertrophy and strength. PMID- 29584519 TI - Physical health problems in people with psychosis: The issue for informal carers. AB - BACKGROUND: Reduced life expectancies are recorded in adults with psychotic disorders. Informal carers play key roles in improving illness outcomes for patients, including significantly reducing rates of relapse and hospitalisation. There is, however, a dearth of literature detailing carers' perspectives on physical health problems in the relatives they care for and implications for those in the caregiving role. The study sought to explore carers' subjective experiences of supporting a relative with psychosis and physical health problems. METHODS: Carers of adults with psychosis were interviewed individually, or as part of a group, about physical health problems in the relatives they care for. RESULTS: Five key themes were identified from the interviews that reflected (1) ubiquity of physical health problems in psychosis, (2) gaps in service provision for those living with mental and physical health problems, (3) carers' role in responding to service gaps, (4) difficult conversations and (5) impact on carer health. CONCLUSION: Service initiatives that are designed to improve patient physical health in psychosis should not overlook the role that informal carers might have in supporting this process. The implications that patient physical health problems present for carer well-being and the quality of the caregiving relationship in psychosis deserve further investigation. PMID- 29584521 TI - Policy and Legal Protection for Breastfeeding and Incarcerated Women in Canada. AB - Most incarcerated women in Canada are mothers. Because women are the fastest growing population in carceral facilities, protecting the rights of incarcerated women to breastfeed their children is increasingly important. There is considerable evidence that incarcerated women in Canada experience poor physical and mental health, isolation, and barriers to care. Incarcerated women and their children could benefit significantly from breastfeeding. This Insight in Policy explores policy and legal protection for breastfeeding in Canada as it relates to carceral facilities, considers key cases regarding breastfeeding rights among incarcerated women, and presents recommendations for policy development and advocacy. The Canadian Constitution and human rights legislation across Canada prohibits discrimination on the basis of gender and includes pregnancy and the possibility of becoming pregnant as a characteristic of gender. Some provinces note that breastfeeding is a characteristic of gender. Women's Wellness Within, a nonprofit organization providing volunteer perinatal support to criminalized women in Nova Scotia, conducted a scan of all provincial and territorial correctional services acts and the federal Corrections and Conditional Release Act: none mention breastfeeding. Protocols for breastfeeding during arrest and lockup by police were not available in any jurisdiction across Canada. International law, including the Convention on the Rights of the Child, the Nelson Mandela Rules, and the Bangkok Rules, have application to the rights of incarcerated breastfeeding women. The Inglis v. British Columbia (Minister of Public Safety) (2013) and Hidalgo v. New Mexico Department of Corrections (2017) decisions are pivotal examples of successful litigation brought forward by incarcerated mothers to advance breastfeeding rights. Improved application and understanding of existent law could advance breastfeeding rights. PMID- 29584520 TI - Coping, resilience and posttraumatic growth among Eritrean female refugees living in Norwegian asylum reception centres: A qualitative study. AB - BACKGROUND: The links between migration and health are well documented. Being a refugee exacerbates migrants' vulnerability through trauma and loss. The aim of this study is to identify sources of resilience, coping and posttraumatic growth in female Eritrean refugees living in Norwegian asylum reception centres. METHOD: The study had a qualitative, descriptive and explorative design with two focus group interviews and 10 individual in-depth interviews. Participants included 18 female Eritrean refugees aged 18-60, who had obtained refugee status and were still living in an asylum reception centre. A content-focused hermeneutic analytic approach was used. RESULTS: Interviewees described the challenges of pre flight and flight trauma, conditions at the refugee centre, communication difficulties and the 'endless' waiting for transfer to a municipality. To cope, they found it helpful to focus on the future and to think positively. Fellowship with and support from fellow Eritrean refugees were essential as they became a proxy family and provided a strong ethnic identity. Their religious belief also helped them cope and gave them hope for the future. DISCUSSION: The interviewees in this study perceived their psychological problems as a normal reaction to what they had been through. Religious belief was an important resilience factor, as was social support, especially from peers. CONCLUSION: The interviewees' coping was based on the realization of their psychological reactions being normal while doing their utmost to focus on their aims and hopes for the future. PMID- 29584522 TI - Physical Activity and Disability: An Analysis on How Activity Might Lower Medical Expenditures. AB - BACKGROUND: This study evaluated the effect of increased physical activity on annual medical expenditures among people with disability, as well as people without disability. METHODS: We performed a cross-sectional study with linked national survey data from 2004 to 2013 Medical Expenditure Panel Survey and from 2002 to 2012 National Health Interview Study. We investigated the effect of physical activity on the annual medical expenditures in 2013 US dollars, among people with and without disability who were 18- to 64-year-old adults. RESULTS: For people with disability, we found a statistically significant effect (P < .05) of physical activity on annual medical expenditures. Among people without disability, being inactive was associated with higher medical expenditures, compared with being sufficiently active. In our counterfactual analysis, among inactive people with disability, increasing activity to even a low level of activity could potentially save on average $2150.06 (95% confidence interval, 770.39 to 3529.72) annual medical costs. CONCLUSIONS: This analysis provides evidence that when an individual with a disability moves from inactive to active, the savings in medical expenditures are substantially larger than the savings for an individual without a disability ($2564.33 vs $393.34). Despite the challenge of participating in physical activity for people with disability, completing "some" activity may have large public health implications. PMID- 29584523 TI - Brain-Behavior Mechanisms for the Transfer of Neuromuscular Training Adaptions to Simulated Sport: Initial Findings From the Train the Brain Project. AB - CONTEXT: A limiting factor for reducing anterior cruciate ligament injury risk is ensuring that the movement adaptions made during the prevention program transfer to sport-specific activity. Virtual reality provides a mechanism to assess transferability, and neuroimaging provides a means to assay the neural processes allowing for such skill transfer. OBJECTIVE: To determine the neural mechanisms for injury risk-reducing biomechanics transfer to sport after anterior cruciate ligament injury prevention training. DESIGN: Cohort study. SETTING: Research laboratory. PARTICIPANTS: Four healthy high school soccer athletes. INTERVENTIONS: Participants completed augmented neuromuscular training utilizing real-time visual feedback. An unloaded knee extension task and a loaded leg press task were completed with neuroimaging before and after training. A virtual reality soccer-specific landing task was also competed following training to assess transfer of movement mechanics. MAIN OUTCOME MEASURES: Landing mechanics during the virtual reality soccer task and blood oxygen level-dependent signal change during neuroimaging. RESULTS: Increased motor planning, sensory and visual region activity during unloaded knee extension and decreased motor cortex activity during loaded leg press were highly correlated with improvements in landing mechanics (decreased hip adduction and knee rotation). CONCLUSION: Changes in brain activity may underlie adaptation and transfer of injury risk reducing movement mechanics to sport activity. Clinicians may be able to target these specific brain processes with adjunctive therapy to facilitate intervention improvements transferring to sport. PMID- 29584524 TI - Impact of Neonatal Intensive Care Unit Admission on Bacterial Colonization of Donated Human Milk. AB - BACKGROUND: Unpasteurized human donor milk typically contains a variety of bacteria. The impact of neonatal intensive care unit (NICU) admission of the donor's infant and duration of lactation on bacterial contamination of human milk is unknown. Research aim: This study aimed (a) to describe the frequency/concentration of skin commensal bacteria and pathogens in unpasteurized human donor milk and (b) to assess the impact of NICU admission and (c) the duration of milk expression on bacterial colonization of donated milk. METHODS: The authors conducted a retrospective cohort study of human milk donated to the Rogers Hixon Ontario Human Milk Bank from January 2013 to June 2014. Milk samples from each donor were cultured every 2 weeks. RESULTS: The study included 198 donor mothers, of whom 63 had infants admitted to the NICU. Of 1,289 cultures obtained, 1,031 (80%) had detectable bacterial growth and 363 (28%) yielded bacterial growth in excess of 107 cfu/L, a local threshold for allowable bacteria prior to pasteurization. The mean (standard deviation) donation period per donor was 13.0 (7.5) weeks. Milk from mothers with NICU exposure had significantly higher concentrations of commensals, but not pathogens, at every time period compared with other mothers. For every 1-month increase in donation from all donors, the odds ratio of presence of any commensal in milk increased by 1.13 (95% confidence interval [1.03, 1.23]) and any pathogen by 1.31 (95% confidence interval [1.20, 1.43]). CONCLUSION: Commensal bacteria were more abundant in donor milk expressed from mothers exposed to neonatal intensive care. Bacterial contamination increased over the milk donation period. PMID- 29584525 TI - Differences in the Modified Disablement in the Physically Active Scale in Those With and Without Chronic Ankle Instability. AB - CONTEXT: The modified disablement in the physically active scale (mDPA) has become a commonly utilized patient-reported outcome instrument (PRO) for physically active patients. However, the factor structure of this instrument has not been verified in individuals with chronic ankle instability (CAI). Furthermore, additional evidence examining the mDPA in individuals with CAI is warranted. OBJECTIVE: The purpose of this study was to verify the factor structure of the modified Disablement in the Physically Active Scale (mDPA) and compare the physical summary component (PSC) and mental summary component (MSC) in those with and without CAI. DESIGN: Cross-sectional Setting: Laboratory Participants: A total of 118 CAI and 81 healthy controls from a convenience sample participated. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: All subjects completed the 16-item mDPA which included the PSC and MSC; higher scores represent greater disablement. To examine the model fit of the mDPA, a single factor and two-factor (PSC and MSC) structure were tested. Group differences were examined with independent t-tests (p<=0.05) and Hedges' g effect sizes (ES). RESULTS: Model fit indices showed the two-factor structure to possesses adequate fit to the data, chi2(101)=275.58, p<0.001, CFI=0.91, RMSEA=0.09 (95%CI=0.08, 0.11), SRMR=0.06. All items loaded significantly and in expected directions on respective subscales (lambda range=0.59-0.87, all p<0.001). The CAI group reported greater disablement as indicated from PSC (CAI:11.45+/-8.30, Healthy:0.62+/-1.80, p<0.001, ES=1.67(95%CI=1.33,1.99)) and MSC (CAI:1.75+/-2.58, Healthy:0.58+/-1.46, p<0.001, ES=0.53(95%CI=0.24,0.82)) scores. CONCLUSION: The two-factor structure of the mDPA was verified. Individuals with CAI reported greater disablement on the PSC compared to healthy controls. The moderate ES on the MSC between groups warrants further investigation. Overall, these results indicate the mDPA is a generic PRO that can be utilized with individuals who have CAI. PMID- 29584526 TI - Corrected QT interval prolongation during anesthetic induction for laryngeal mask airway insertion with or without cisatracurium. AB - Objective This study was performed to observe the occurrence of corrected QT (QTc) interval prolongation during anesthetic induction for laryngeal mask airway insertion and the effects of cisatracurium administration on the QTc interval. Methods Eighty-eight patients were assigned to two groups: the cisatracurium administration group (n = 45) and non-cisatracurium administration group (n = 43). The QTc interval was continuously recorded by a 12-lead Holter electrocardiogram beginning in the hospital ward and continuing until after anesthetic induction. Results In the cisatracurium administration group, the QTc interval significantly increased from 417.9 +/- 27.9 to 451.6 +/- 32.5 ms after arrival in the operating room and significantly decreased to 432.4 +/- 32.5 ms after a 15-minute rest; it significantly increased to 459.7 +/- 23.8 ms again after propofol and fentanyl injection. However, the QTc interval decreased after cisatracurium injection. In the non-cisatracurium administration group, the QTc interval initially showed changes similar to those in the cisatracurium group until fentanyl and propofol were injected. Conclusions The QTc interval was significantly prolonged on arrival in the operating room and after propofol and fentanyl injection. The QTc interval did not significantly change by laryngeal mask airway insertion regardless of the administration of cisatracurium. PMID- 29584527 TI - Teacher-Level Factors, Classroom Physical Activity Opportunities, and Children's Physical Activity Levels. AB - BACKGROUND: Classroom-based physical activity (CBPA) breaks are a cost-effective strategy to promote physical activity (PA) at school. Despite teachers' critical roles in sustained implementation of CBPA breaks, few studies examined the association of teacher-level factors with student PA levels, and none focused on rural schools. METHODS: We monitored children's PA levels over 4 consecutive school days at 6 rural Oregon elementary schools with Walk4Life pedometers. During the same week, teachers recorded all student PA opportunities (recess, PE, and CBPA breaks) and answered a 26-item questionnaire about factors influencing their use of CBPA breaks. Mixed-effects models were used to associate teacher level factors and PA opportunities with children's moderate to vigorous PA (MVPA; in minutes per day), controlling for child-level covariates. RESULTS: When teachers valued PA, students accumulated more MVPA (1.07 min/d; P < .01) than students of teachers reporting low PA value. Students did more MVPA (1 min/d; P < .001) when teachers agreed the school operating conditions posed barriers to providing PA than when teachers disagreed that barriers existed. PE classes contributed significantly to student's PA levels. CONCLUSION: Provision of PE, increasing teacher value for PA, and further investigation of how teacher-level factors relate to students' MVPA levels during CBPA breaks at rural elementary schools are warranted. PMID- 29584528 TI - The Cortisol Awakening Response: Association With Training Load in Endurance Runners. AB - : The cortisol awakening response (CAR) is commonly used as a marker of psychological stress; however, it is unknown whether CAR is affected by regular physical-exercise-induced stress. PURPOSE: To assess the relationship between training load and CAR. METHODS: Recreational endurance athletes were recruited from local running clubs. Subjects (n = 15) completed training logs for 2 wk, with various training loads, including psychometric analysis (Recovery-Stress Questionnaire for Athletes). Subjects provided saliva samples each day immediately after waking and 30 min postwaking. Samples were analyzed for cortisol concentration via enzyme-linked immunosorbent assay and subsequently were analyzed for CAR and CAR%. Daily training load was calculated and analyzed as training impulse. Simple linear regression was used to assess the relationship between CAR and training impulse. RESULTS: CAR (r2 = .352, P = .025) and CAR% (r2 = .373, P = .012) both showed a significant negative relationship with training load. CONCLUSIONS: These results suggest that CAR is affected by regular exercise training loads in recreational athletes. It is recommended that future CAR research control for fitness level and exercise training load in physically active populations. PMID- 29584529 TI - Characterization and Pharmacokinetics of Triamcinolone Acetonide-Loaded Liposomes Topical Formulations for Vitreoretinal Drug Delivery. AB - PURPOSE: To achieve a safer alternative to intravitreal injection of corticosteroids, we developed and characterized triamcinolone acetonide-loaded liposomes formulations (TA-LFs) to be used topically for vitreoretinal drug delivery. METHODS: Four different 0.2% TA-LFs (TA-LF1 to TA-LF4) were generated and submitted to physicochemical characterization. Posteriorly, an ex vivo diffusion assay was performed using rabbit corneas as membranes. Finally, concentrations of triamcinolone acetonide (TA) were determined by high performance liquid chromatography in ocular tissues from New Zealand white rabbits after multiple topical doses of TA-LF2 (6 times per day, 14 days). In addition, toxicity and tolerability of TA-LF2 was evaluated by cell viability assay and eye examination of study animals, respectively. RESULTS: TA-LF2 was the most stable formulation maintaining a stable hidrogenion potential (pH) at 30 and 40 degrees C and even improving encapsulation with higher temperature. TA-LF2 and TA-LF3 presented the best diffusion performance in vitro reaching the highest TA concentrations after 8 h of follow-up. In vivo diffusion and pharmacokinetics analysis showed that concentrations of TA in retina and vitreous reached the highest peak at 12 h after topical administration of TA-LF2 (252.10 +/- 90.00 ng/g and 32.6 +/- 10.27 ng/g, respectively) and subsequently decline to 24.0 +/- 11.72 ng/g and 19.5 +/- 13.14 ng/g, respectively, at 14 days of follow-up. Finally, cell viability was unaffected by TA-LF2, and no increase in intraocular pressure nor ocular alterations were observed after topical administration of this formulation in rabbits. CONCLUSION: TA-loaded liposomes, administered topically, can deliver TA in the vitreous cavity and reach the retina efficiently. PMID- 29584530 TI - Monitoring Training Load, Recovery, and Performance of Brazilian Professional Volleyball Players During a Season. AB - PURPOSE: To describe and analyze the distribution of internal training load (ITL), recovery, and physical performance of professional volleyball players throughout 1 season. METHODS: Fifteen male professional Brazilian volleyball players participated in this study. The session rating of perceived exertion (s RPE) and Total Quality Recovery (TQR) score were collected daily for 36 wk. s-RPE was collected after each training session, and TQR, before the first session of the day. The sum of the ITL of each session during the week, training monotony, strain, acute?chronic workload ratio, match difficulty score, and average of the TQR scores were recorded for the analysis. In addition, the athletes performed countermovement-jump (CMJ) tests with and without the use of the arms 4 times over the season. RESULTS: The season mean weekly ITL was 3733 (1228) AU and the TQR was 15.02 (0.71). The ITL and recovery demonstrated undulating dynamics over the 36 wk, with higher weekly ITL in the preparatory periods (F = 50.32; P < .001) and worse recovery during the main competition (F = 6.47; P = .004). Negative correlations were found between TQR and ITL variables (P < .05). There was improvement and maintenance in CMJ tests without (F = 11.88; P < .001) and with (F = 16.02; P < .001) the use of the arms after the preparatory periods. CONCLUSIONS: The ITL variables, recovery, and physical performance changed significantly throughout a professional volleyball season. Despite the decrease in ITL during the main competitive period, the correct distribution of weekly ITL seems to be very important to guarantee the best recovery of athletes. PMID- 29584531 TI - Historical Methods. PMID- 29584532 TI - Validation of the French Version of Conners' Parent Rating Scale-Revised, Short Version (CPRS-R:S): Scale Measurement Invariance by Sex and Age. AB - OBJECTIVE: ADHD is one of the most frequent neurodevelopmental disorders. In addition to clinical assessment, its diagnosis requires the use of validated and reliable behavior questionnaires such as the Conners' Parent Rating Scale Revised: Short Form (CPRS-R:S). Though various French versions of the CPRS-R:S have been already put to use in clinical practice and research, only a few have undergone a stringent validation process. After a previous validation of the factorial structure of Lausanne French version, we sought here for the analysis of its invariance across sex and age. METHOD: This validation step was carried out in a rather homogeneous French population of 365 boys and 374 girls from a single school. Two-age classes were considered: children (boys and girls) aged 9 to 11 years ( n = 258) and adolescents aged 12 to 15 years ( n = 481). RESULTS: Regarding age, dimension Oppositional showed a strong invariance whereas dimensions Hyperactivity and Cognitive problems/Inattention showed a partially strong invariance. Regarding sex, dimensions Oppositional and Hyperactivity showed a partially strong invariance whereas dimension Cognitive problems/Inattention showed a partially weak invariance. The distribution of the CPRS-R:S scores is given by sex and age class. CONCLUSION: The Lausanne French version of the CPRS-R:S, already validated regarding its factorial structure, internal consistency, and reliability, is here validated regarding its invariance across sex and age. Caution should be taken in using dimension Cognitive problems/Inattention in comparisons between boys and girls. PMID- 29584533 TI - Rehabilitation Exercises for the Gluteus Minimus Muscle Segments - An Electromyography Study. AB - CONTEXT: The gluteus minimus (GMin) muscle consists of two uniquely oriented segments that have potential for independent function, and have different responses to pathology and ageing. For healthy, young adults it is unknown which rehabilitation exercises specifically target the individual segments. OBJECTIVE: To quantify segmental GMin activity for six common lower limb rehabilitation exercises in healthy young adults, and determine if significant differences exist in segmental activity levels between the exercises. METHOD: Six common lower limb rehabilitation exercises were performed by ten healthy young adults with fine wire electromyography (EMG) electrodes inserted into the anterior and posterior segments of the GMin muscle. MAIN OUTCOME MEASURES: EMG signals were recorded and median normalised exercise activity levels were reported and compared for each GMin segment across the six exercises. RESULTS: High activity levels were generated in the anterior segment by the resisted hip abduction-extension exercise (51% maximum voluntary isometric contraction (MVIC)), while for the posterior segment high activity levels were produced by the single leg bridge (49% MVIC), the side lie hip abduction (43% MVIC), the resisted hip abduction extension exercise (43% MVIC), and the single leg squat (40% MVIC). There were significant differences (P < .05) in the median EMG activity levels for the anterior GMin segment but not for the posterior GMin segment across some of the exercises with large effect sizes. CONCLUSIONS: Targeted rehabilitation exercises graded by exercise intensity can be prescribed specifically for the anterior and posterior GMin segments to aid in restoration of hip function following injury or ageing. PMID- 29584534 TI - The pro-inflammatory role of platelets in cancer. AB - Thrombosis is a frequent issue in cancer patients. Tumor-induced platelet activation and coagulation does not only constitute a significant risk for thrombosis, but also contribute to tumor progression by promoting critical processes such as angiogenesis and metastasis. In addition to their role in hemostasis, platelets are increasingly recognized as regulators of inflammation. By modulating the immune system, platelets regulate several aspects of cancer associated pathology. Platelets influence the inflammatory response in cancer by affecting the activation status of the endothelium and by recruiting leukocytes to primary and metastatic tumor sites, as well as to distant organs unaffected by tumor growth. Furthermore, platelets participate in the formation of neutrophil extracellular traps, which can promote metastasis, thrombosis, and contribute to organ failure. In this review, we discuss the role of platelets as coordinators of the immune system during malignant disease and the potential of targeting platelets to prevent cancer-associated pathology. PMID- 29584535 TI - Intracranial hypertension related to cerebral venous thrombosis; and acute ischemic stroke with micro-infarcts associated with IgG4-related disease. AB - IgG4-related systemic disease (IgG4-RD) is characterized by an inflammatory reaction rich in IgG4-positive plasma cells, affecting multiple organs. This report describes a case who was diagnosed with IgG4-RD, having cerebral venous thrombosis and a subsequent acute ischemic stroke of undetermined cause. A 47 year-old woman presented with headache, visual disturbance and eyelid swelling and two years later she was admitted with acute attacks of mild left lower limb sensory-motor monoparesis. Indirect immunohistochemistry assay showed elevated level of IgG4, labeling neurons of the central nervous system, suggesting an immunological process possibly affecting vascular structures. Our experience suggests that IgG4-RD may be considered in patients with ischemic stroke and cerebral venous system involvement. PMID- 29584536 TI - Examining Practice and Learning Effects with Serial Administration of the Clinical Reaction Time Test in Healthy Young Athletes. AB - CONTEXT: The Clinical Reaction Time (RTclin) test has been recommended as a valid test for assessing concussion and determining recovery of reaction time function following concussion. However, it is unknown whether repeat assessment, as is used in post-concussion testing, is affected by learning or practice phenomena. OBJECTIVE: To determine if a practice or learning effect is present with serial administration of the RTclin test. DESIGN: Randomized control trial. SETTING: University athletic training clinics. PARTICIPANTS: One hundred and twelve healthy collegiate athletes (age = 19.46y +/- 1.34). INTERVENTION(S): The control group completed the RTclin test on Days 1 and 60. The experimental group completed the RTclin test on Days 1, 2, 3, 7 and 60. MAIN OUTCOME MEASURE(S): Reaction time as measured with the RTclin test. RESULTS: The difference in RTclin test performance from Day 1 to Day 60 was not significant (Mean Change = -2.77 +/ 14.46ms, P = .421, 95%CIs: -6.40, .862) between groups. The experimental group experienced significant improvement (lambda = .784, F4,49 = 3.365, P= .016, eta2= .216, power =.81) with acute repeat testing. However, post-hoc analysis did not reveal a significant difference between scores during the 5 test periods. CONCLUSIONS: The results suggest serial administration of the RTclin test does not produce a practice or learning effect. Clinicians, however, should be cautious as the results do provide evidence patients may demonstrate improved scores when testing occurs on repetitive days after initial exposure to the test. PMID- 29584537 TI - Early mortality in elderly patients undergoing treatment for multiple myeloma in real-world practice. AB - Objectives This study was performed to analyze the risk factors for early mortality (EM) in elderly patients undergoing treatment for multiple myeloma (MM) in real-world clinical practice. Methods Retrospective data from 108 elderly patients who were newly diagnosed with MM from January 2007 to July 2015 were analyzed in a single hematology center. EM was defined as death of any cause within 12 months after diagnosis. A multivariate regression model was used to evaluate EM. Results EM occurred in 16 (14.8%) elderly patients with newly diagnosed MM. The most common cause of death was infection (10/16, 62.5%). In the multivariate analysis, only an age of >=75 years, International Staging System (ISS) stage III disease, and high lactate dehydrogenase concentration were significantly and independently associated with EM. Conclusion Our results suggest that infection is the leading cause of EM in elderly patients with MM. An age of >=75 years, ISS stage III disease, and a high lactate dehydrogenase concentration are significant predictors of EM. We should further target this higher-risk patient population to define personalized therapy with which to improve outcomes. PMID- 29584538 TI - Reducing Fear of Reinjury and Pain Perception Among Athletes with First Time Anterior Cruciate Ligament Reconstructions by Implementing Imagery Training. AB - CLINICAL SCENARIO: Injuries are an inevitable part of competitive sports as well a recreational activities. Research shows that one of the most common musculoskeletal complaints that accounts for approximately 48 out of 1,000 patients are knee related injuries.1 As noted, approximately nine percent of these knee complaints are related to anterior cruciate ligament (ACL) injuries.2, 3 The ACL is commonly injured in contact sports via a non-contact action such as planting, cutting, landing on a hyperextended knee, or pivoting and sudden deceleration.4 Typically, athletes report feeling immediate pain, hearing a pop and resulting in progressive knee swelling; as well as difficulty ambulating. The ACL is one of the major ligaments that provides stability to the knee joint by preventing anterior translation of the femur in the closed kinetic chain.5 Therefore, most of the time, a ruptured ACL results in reconstructive surgery aimed at repairing the ligament. Athletes will often choose reconstructive surgery in efforts to return to physical activity. A major outcome measure that assesses the success of an ACL reconstructive surgery is the ability to return to sports or recreational activity.6 While surgery is effective at repairing the ruptured ligament and restoring ligamentous function, for the most part, the percentage of athletes that return to a competitive level of physical activity is only 44%.4 Of these 44% that report not returning to pre-injury activity, 24% report that the main factors preventing their return is fear or reinjury and pain.4, 7 The inability to return to previous level of activity can be stressful and mentally frustrating for athletes. Taking into consideration how the psychological aspects of the injury affect an athlete's sports performance, it is crucial to address psychological factors during physical rehabilitation for an athlete to rebuild confidence and overcome fear of reinjury. Currently, most physiotherapy and rehabilitation research has primarily focused on the physical treatment without focus on the psychological aspects of recovery following an injury.5, 7 The use of imagery as a psychological interventions has been suggested to be effective at reducing anxiety, tension and pain while promoting and encouraging healing after an injury. Imagery is defined as a process of performing a skill in one's mind using the senses (touch, feel, smell, vision, etc.,) without any overt actions.8 Incorporating a therapeutic intervention that targets the psychological effects on an athletes' ability to return to sport is necessary to assure that the patient is both physically and mentally prepared to return to activity. Therefore, the purpose of the critically appraised topic (CAT) was to determine if imagery training in combination with standard physical therapy is a suitable option to reduce the fear of reinjury and pain perception among first time ACL reconstruction patients. PMID- 29584539 TI - Effectiveness of the I2AO2 interdisciplinary programme led by nurses on metabolic syndrome and cardiovascular risk: a randomized, controlled trial. AB - Objective To evaluate the effectiveness of an interdisciplinary programme led by nurses in relation to metabolic syndrome (MS) and cardiovascular risk (CVR). Methods This randomized, controlled, clinical trial included 74 patients diagnosed with MS (experimental group [EG], n = 37; control group [CG], n = 37). The intervention consisted of a 12-month interdisciplinary programme (pre-test, 6 months of intervention, 12 months of intervention, and 1-year follow-up post intervention) coordinated by nursing. Results We found a progressive and significant reduction for all clinical, biochemical, and anthropometric parameters analysed at different time points. In the EG, remission of MS by 48.1% in the short term was observed (83.8% in the medium term) and maintained at 1 year post-intervention. In the CG, the prevalence of MS increased by 2.7% from the initial evaluation to study completion. A similar trend was observed for CVR. In the EG, 100% of subjects had a moderate-low risk of CVR at 1 year post intervention, whereas the CG had CVR in all categories. Conclusion An interdisciplinary, nurse-led programme improves participants' metabolic and cardiovascular health, while maintaining long-term effects. Our findings suggest an important role of the professional nurse as a nexus between the patient, different professionals, and the community. PMID- 29584540 TI - Anterior versus posterior surgical approach for lumbosacral tuberculosis. AB - Objective To compare two different approaches for the treatment of lumbosacral tuberculosis. Patients and Methods In total, 115 patients who were surgically treated in our department from July 2010 to July 2014 were included in this retrospective study. They were divided into the anterior and posterior approach groups. Intraoperative hemorrhage; the surgery time; the Cobb angle preoperatively, postoperatively, and at the follow-up visit (2 years postoperatively); visual analog scale (VAS) pain scores before and after surgery; and Oswestry Disability Index (ODI) scores before and after surgery were compared between the two groups. Results The Cobb angle and VAS and ODI scores were significantly improved in both groups after surgery. Significant differences were found in the operation time, intraoperative hemorrhage, Cobb angle correction, and loss of correction at the last follow-up. No significant differences were found in the VAS and ODI scores between the groups. Conclusions The posterior approach is superior to the anterior approach with respect to the surgery time, intraoperative hemorrhage, and Cobb angle postoperatively and at the last follow up. When both approaches can be carried out for a patient with lumbosacral tuberculosis, the posterior approach should be favored over the anterior approach. PMID- 29584541 TI - Approximate confidence intervals for the likelihood ratios of a binary diagnostic test in the presence of partial disease verification. AB - The classic parameters used to assess the accuracy of a binary diagnostic test (BDT) are sensitivity and specificity. Other parameters used to describe the performance of a BDT are likelihood ratios (LRs). The LRs depend on the sensitivity and the specificity of the diagnostic test, and they reflect how much greater the probability of a positive or negative diagnostic test result for individuals with the disease than that for the individuals without the disease. In this study, several confidence intervals are studied for the LRs of a BDT in the presence of missing data. Two confidence intervals were studied through the method of maximum likelihood and seven confidence intervals were studied by applying the multiple imputation by chained equations method. A program in R software has been written that allows us to solve the estimation problem posed. The results obtained have been applied to the two real examples. PMID- 29584542 TI - Toward Decentralized Agrigenomic Surveillance? A Polymerase Chain Reaction Restriction Fragment Length Polymorphism Approach for Adaptable and Rapid Detection of User-Defined Fungal Pathogens in Potato Crops. AB - Agrigenomics is one of the emerging focus areas for omics sciences. Yet, agrigenomics differs from medical omics applications such as pharmacogenomics and precision medicine, by virtue of vastly distributed geography of applications at the intersection of agriculture, nutrition, and genomics research streams. Crucially, agrigenomics can address diagnostics and safety surveillance needs in remote and rural farming communities or decentralized food, crop, and environmental monitoring programs for prompt, selective, and differential identification of pathogens. A case in point is the potato crop that serves as a fundamental nutritional source worldwide. Decentralized potato crop and plant protection facilities are pivotal to minimize unnecessary, preemptive use of broad-spectrum fungicides, thus helping to curtail the costs, environmental burden, and the development of resistance in opportunistic human pathogenic fungi. We report here a polymerase chain reaction-restriction fragment length polymorphism approach that is sensitive and adaptable in detection and broad identification of fungal pathogens in potato crops, with a view to future decentralized agrigenomic surveillance programs. Notably, the fingerprinting patterns obtained by the method fully differentiated 12 fungal species examined in silico, with 10 of them also tested in vitro. The method can be scaled up through improvements in electrophoresis and enzyme panel for adaption to other crops and/or pathogens. We suggest that decentralized and integrated agrosurveillance programs and translational agrigenomic programs can inform future innovations in multidomain biosecurity, particularly across omics applications from agriculture and nutrition to clinical medicine and environmental biosafety. PMID- 29584543 TI - Distinguishing Molecular Features of Allergic Fungal Rhinosinusitis. AB - Objective Allergic fungal rhinosinusitis (AFRS) is a clinical subtype of chronic rhinosinusitis with nasal polyps (CRSwNP), characterized by eosinophilic mucin, evidence of fungal elements within the mucin, fungal-specific type I hypersensitivity, and characteristic computed tomography findings. It remains controversial whether AFRS represents a disease with a unique pathophysiology from chronic rhinosinusitis or is merely a severe form of CRSwNP. The goal of this study was to identify molecular features unique to AFRS. Study Design Cross sectional case-control. Setting Single academic tertiary referral institution. Subjects and Methods Subjects included 86 patients undergoing endoscopic sinus surgery: CRSwNP (n = 34), AFRS (n = 37), and healthy controls (n = 15). Pathway and correlation analyses were performed with whole-genome microarray data for study patients undergoing surgery for recalcitrant chronic rhinosinusitis. Our findings were confirmed with quantitative polymerase chain reaction and immunohistochemical studies. Results AFRS was uniquely characterized by a pronounced association with adaptive T helper 2-associated immune gene expression. AFRS exhibited altered expression of proteins associated with secretory salivary peptides-namely, histatin, a peptide with known antifungal activity in the oral cavity. Furthermore, the expression of histatins correlated negatively with that of type 2 inflammatory mediators. We confirm the decreased expression of histatins in AFRS when compared with CRSwNP by quantitative polymerase chain reaction and localized its expression to a submucosal cell population. Conclusion There exist clear molecular profiles that distinguish AFRS from CRSwNP. This divergence translates into an altered ability to control fungal growth and may in part explain some of the phenotypical differences between CRSwNP and AFRS. PMID- 29584544 TI - Drivers of treatment patterns in patients with chronic lymphocytic leukemia stopping ibrutinib or idelalisib therapies. AB - Novel therapies including kinase inhibitors (KI) have led to high and durable response in patients with chronic lymphocytic leukemia (CLL), however, some patients stop therapy. This study evaluates reasons for treatment changes among CLL patients who stopped KI in real-world practice. Sixty-nine US oncologists/hematologists provided patient-level data abstracted from charts of CLL adult patients who initiated a KI and later (1) switched to another anti neoplastic regimen (Switched cohort), (2) discontinued the KI and remained untreated (Discontinued cohort), or (3) restarted the same KI after an interruption of >=60 days (Restarted cohort). Demographics, clinical/treatment characteristics, and reasons for stopping, restarting, and switching the KI therapy were described. In the Switched cohort, reasons for stopping included disease progression (72.5%), low/no disease activity (3.9%), adverse event [AE]/ intolerance/comorbidity (15.7%), and planned cellular therapies (7.9%). In the Discontinued cohort, approximately half (46.0%) of patients stopped KI therapy because they were terminally ill/died, or were moved to best supportive care - these patients were older, had more severe disease, and high comorbidity burden. The other half (54.0% of patients) stopped due to low/no disease activity (24.0%), AEs/toxicity (12.0%), or patient-requested drug holiday (18.0%). In the Restarted cohort, the most common reasons for stopping KIs were patient request (37.3%), AEs/intolerance (31.4%), and economic reasons (10%). Patients restarted when disease progressed (60.8%) or when they recovered from the AE (33%). Reasons for KI stop and subsequent treatment patterns were varied and multifactorial, suggesting heterogeneous disease management and a need for more evidence around supporting strategies and physician education. PMID- 29584545 TI - Antitumor Activity of Nivolumab in Recurrent and Metastatic Nasopharyngeal Carcinoma: An International, Multicenter Study of the Mayo Clinic Phase 2 Consortium (NCI-9742). AB - Purpose This multinational study evaluated the antitumor activity of nivolumab in nasopharyngeal carcinoma (NPC). Tumor and plasma-based biomarkers were investigated in an exploratory analysis. Patients and Methods Patients with multiply pretreated recurrent or metastatic NPC were treated with nivolumab until disease progression. The primary end point was objective response rate (ORR) and secondary end points included survival and toxicity. The expression of programmed death-ligand 1 (PD-L1) and human leukocyte antigens A and B in archived tumors and plasma clearance of Epstein-Barr virus DNA were correlated with ORR and survival. Results A total of 44 patients were evaluated and the overall ORR was 20.5% (complete response, n = 1; partial response, n = 8). Nine patients received nivolumab for > 12 months (20%). The 1-year overall survival rate was 59% (95% CI, 44.3% to 78.5%) and 1-year progression-free survival (PFS) rate was 19.3% (95% CI, 10.1% to 37.2%). There was no statistical correlation between ORR and the biomarkers; however, a descriptive analysis showed that the proportion of patients who responded was higher among those with PD-L1 positive tumors (> 1% expression) than those with PD-L1-negative tumors. The loss of expression of one or both human leukocyte antigen class 1 proteins was associated with better PFS than when both proteins were expressed (1-year PFS, 30.9% v 5.6%; log-rank P = .01). There was no association between survival and PD-L1 expression or plasma Epstein-Barr virus DNA clearance. There was no unexpected toxicity to nivolumab. Conclusion Nivolumab has promising activity in NPC and the 1-year overall survival rate compares favorably with historic data in similar populations. Additional evaluation in a randomized setting is warranted. The biomarker results were hypothesis generating and validation in larger cohorts is needed.

AB - Purpose Genetic alterations causing overexpression of programmed death-1 ligands are near universal in classic Hodgkin lymphoma (cHL). Nivolumab, a programmed death-1 checkpoint inhibitor, demonstrated efficacy in relapsed/refractory cHL after autologous hematopoietic cell transplantation (auto-HCT) in initial analyses of one of three cohorts from the CheckMate 205 study of nivolumab for cHL. Here, we assess safety and efficacy after extended follow-up of all three cohorts. Methods This multicenter, single-arm, phase II study enrolled patients with relapsed/refractory cHL after auto-HCT treatment failure into cohorts by treatment history: brentuximab vedotin (BV)-naive (cohort A), BV received after auto-HCT (cohort B), and BV received before and/or after auto-HCT (cohort C). All patients received nivolumab 3 mg/kg every 2 weeks until disease progression/unacceptable toxicity. The primary end point was objective response rate per independent radiology review committee. Results Overall, 243 patients were treated; 63 in cohort A, 80 in cohort B, and 100 in cohort C. After a median follow-up of 18 months, 40% continued to receive treatment. The objective response rate was 69% (95% CI, 63% to 75%) overall and 65% to 73% in each cohort. Overall, the median duration of response was 16.6 months (95% CI, 13.2 to 20.3 months), and median progression-free survival was 14.7 months (95% CI, 11.3 to 18.5 months). Of 70 patients treated past conventional disease progression, 61% of those evaluable had stable or further reduced target tumor burdens. The most common grade 3 to 4 drug-related adverse events were lipase increases (5%), neutropenia (3%), and ALT increases (3%). Twenty-nine deaths occurred; none were considered treatment related. Conclusion With extended follow-up, responses to nivolumab were frequent and durable. Nivolumab seems to be associated with a favorable safety profile and long-term benefits across a broad spectrum of patients with relapsed/refractory cHL. PMID- 29584547 TI - Molecular Characterization and Mortality From Breast Cancer in Men. AB - Purpose Limited data exist on the molecular biology, treatment, and outcomes of breast cancer in men, and much of our understanding in this area remains largely an extrapolation from data in women with breast cancer. Materials and Methods We studied men and women with hormone receptor-positive breast cancer and the 21 gene Breast Recurrence Score (RS) results. Differences in clinical characteristics and gene expression were determined, and distribution of RS results was correlated with 5-year breast cancer-specific survival (BCSS) and overall survival. Results There were 3,806 men and 571,115 women. Men were older than women (mean age, 64.2 v 59.1 years; P < .001). RS < 18 predominated in both genders, but RS >= 31 was more frequent in men (12.4% v 7.4%; P < .001), as were very low scores (RS < 11; 33.8% v 22.1%; P < .001). Mean gene expression was higher in men for the estrogen receptor (ER), proliferation, and invasion groups. ER was lowest and progesterone receptor was highest in women younger than 50 years of age, with a progressive increase in ER with age. Men younger than 50 years of age had slightly lower ER and progesterone receptor compared with older men. Survival data were available from SEER for 322 men and 55,842 women. Five year BCSS was 99.0% (95% CI, 99.3% to 99.9%) and 95.9% (95% CI, 87.6% to 98.7%) for men with RS < 18 and RS 18-30, respectively, and for women, it was 99.5% (95% CI, 99.4% to 99.6%) and 98.6% (95% CI, 98.4% to 98.8%), respectively. RS >= 31 was associated with an 81.0% 5-year BCSS in men (95% CI, 53.3% to 93.2%) and 94.9% 5-year BCSS (95% CI, 93.9% to 95.7%) in women. Five-year BCSS and overall survival were lower in men than in women. Conclusion This study reveals some distinctive biologic features of breast cancer in men and an important prognostic role for RS testing in both men and women. PMID- 29584548 TI - Overall Survival Benefit in Patients With Rituximab-Refractory Indolent Non Hodgkin Lymphoma Who Received Obinutuzumab Plus Bendamustine Induction and Obinutuzumab Maintenance in the GADOLIN Study. AB - Purpose To perform an updated analysis of the randomized phase III GADOLIN trial in patients with rituximab-refractory indolent non-Hodgkin lymphoma treated with obinutuzumab (GA101; G) and bendamustine (B). Patients and Methods Patients with histologically documented, rituximab-refractory CD20+ indolent non-Hodgkin lymphoma received G 1,000 mg (days 1, 8, and 15, cycle 1; day 1, cycles 2 to 6) plus B 90 mg/m2/d (days 1 and 2, all cycles) or B 120 mg/m2/d monotherapy. Patients who did not experience disease progression with G-B received G maintenance (1,000 mg every 2 months) for up to 2 years. The primary end point was progression-free survival (PFS). Results Of 413 randomly assigned patients (intention-to-treat [ITT]: G-B, n = 204; B monotherapy, n = 209), 335 had follicular lymphoma (FL; G-B, n = 164; B monotherapy, n = 171). After a median follow-up of 31.8 months, median PFS in ITT patients was 25.8 months (G-B) and 14.1 months (B monotherapy; hazard ratio [HR], 0.57; 95% CI, 0.44 to 0.73; P < .001). Overall survival (OS) also was prolonged (HR, 0.67; 95% CI, 0.47 to 0.96; P = .027). PFS and OS benefits were similar in patients with FL. Grade 3 to 5 adverse events (AEs) were reported by 148 (72.5%) and 133 (65.5%) patients in the G-B and B monotherapy arms, respectively, most commonly neutropenia (G-B, 34.8%; B monotherapy, 27.1%), thrombocytopenia (10.8% and 15.8%), anemia (7.4% and 10.8%), and infusion-related reactions (9.3% and 3.4%). Serious AEs occurred in 89 G-B patients (43.6%) and 75 B monotherapy patients (36.9%); fatal AEs occurred in 16 (7.8%) and 13 (6.4%), respectively. Conclusion This updated analysis confirms the PFS benefit for G-B shown in the primary analysis. A substantial OS benefit also was demonstrated in the ITT population and in patients with FL. Toxicity was similar for both treatments. PMID- 29584549 TI - Randomized Phase II Trial of Carboplatin-Paclitaxel Versus Carboplatin-Paclitaxel Trastuzumab in Uterine Serous Carcinomas That Overexpress Human Epidermal Growth Factor Receptor 2/neu. AB - Purpose Uterine serous carcinoma is a rare, aggressive variant of endometrial cancer. Trastuzumab is a humanized monoclonal antibody that targets human epidermal growth factor receptor 2 (HER2)/neu, a receptor overexpressed in 30% of uterine serous carcinoma. This multicenter, randomized phase II trial compared carboplatin-paclitaxel with and without trastuzumab in patients with advanced or recurrent uterine serous carcinoma who overexpress HER2/neu. Methods Eligible patients had primary stage III or IV or recurrent HER2/neu-positive disease. Participants were randomly assigned to receive carboplatin-paclitaxel (control arm) for six cycles with or without intravenous trastuzumab (experimental arm) until progression or unacceptable toxicity. The primary end point was progression free survival, which was assessed for differences between treatment arms via one sided log-rank tests. Results From August 2011 to March 2017, 61 patients were randomly assigned. Forty progression-free survival-related events occurred among 58 evaluable participants. Among all patients, median progression-free survival was 8.0 months (control) versus 12.6 months (experimental; P = .005; hazard ratio [HR], 0.44; 90% CI, 0.26 to 0.76). Similarly, median progression-free survival was 9.3 (control) versus 17.9 (experimental) months among 41 patients with stage III or IV disease undergoing primary treatment ( P = .013; HR, 0.40; 90% CI, 0.20 to 0.80) and 6.0 (control) versus 9.2 months (experimental), respectively, among 17 patients with recurrent disease ( P = .003; HR, 0.14; 90% CI, 0.04 to 0.53). Toxicity was not different between treatment arms, and no unexpected safety signals emerged. Conclusion Addition of trastuzumab to carboplatin-paclitaxel was well tolerated and increased progression-free survival. These encouraging results deserve further investigation to determine their impact on overall survival in patients with advanced or recurrent uterine serous carcinoma who overexpress HER2/neu.

PMID- 29584550 TI - Association of Cardiovascular Risk Factors With Cardiac Events and Survival Outcomes Among Patients With Breast Cancer Enrolled in SWOG Clinical Trials. AB - Background Cardiovascular disease is the primary cause of death among patients with breast cancer. However, the association of cardiovascular-disease risk factors (CVD-RFs) with long-term survival and cardiac events is not well studied. Methods We examined SWOG (formerly the Southwest Oncology Group) breast cancer trials from 1999 to 2011. We identified baseline diabetes, hypertension, hypercholesterolemia, and coronary artery disease by linking trial records to Medicare claims. The primary outcome was overall survival. Patients with both baseline and follow-up claims were examined for cardiac events. Cox regression was used to assess the association between CVD-RFs and outcomes. Results We identified 1,460 participants older than 66 years of age from five trials; 842 were eligible for survival outcomes analysis. At baseline, median age was 70 years, and median follow-up was 6 years. Hypertension (73%) and hypercholesterolemia (57%) were the most prevalent conditions; 87% of patients had one or more CVD-RF. There was no association between any of the individual CVD-RFs and overall survival except for hypercholesterolemia, which was associated with improved overall survival (hazard ratio [HR], 0.73; 95% CI, 0.57 to 0.93; P = .01). With each additional CVD-RF, there was an increased risk of death (HR, 1.23; 95% CI, 1.08 to 1.40; P = .002), worse progression-free survival (HR, 1.12; 95% CI, 1.00 to 1.25; P = .05), and marginally worse cancer-free survival (HR, 1.15; 95% CI, 0.99 to 1.34; P = .07). The relationship between baseline CVD-RFs and cardiac events was analyzed in 736 patients. A strong linear association between the number of CVD-RFs and cardiac event was observed (HR per CVD-RF, 1.41; 95% CI, 1.17 to 1.69; P < .001). Conclusion Among participants in clinical trials, each additional baseline CVD-RF was associated with an increased risk of cardiac events and death. Efforts to improve control of modifiable CVD RFs are needed, especially among those with multiple risk factors. PMID- 29584552 TI - SIRT1 in Colorectal Cancer: A Friend or Foe? PMID- 29584553 TI - Ultrathin CAD-CAM Ceramic Occlusal Veneers and Anterior Bilaminar Veneers for the Treatment of Moderate Dental Biocorrosion: A 1.5-Year Follow-Up. AB - Dental biocorrosion can produce a devastating impact on oral health. The restorative phase of the treatment should not cause additional damage of the remaining sound tooth structure. Ultrathin occlusal veneers are a conservative alternative to traditional onlays and complete crowns for the treatment of severe biocorrosive lesions. This strategy is explained in the present case report through a full-mouth rehabilitation of a patient with moderate biocorrosion. Maxillary anterior teeth were restored using the bilaminar technique (lingual direct composite veneers with labial ceramic veneers) and posterior teeth using ultrathin CAD-CAM ceramic occlusal veneers. The technical aspects required for the implementation of this new restorative design are presented with a special emphasis on the control of tooth preparation based on diagnostic wax-up, provisionalization, and the use of CAD-CAM technology. PMID- 29584554 TI - National Trends in Vestibular Schwannoma Surgery: Influence of Patient Characteristics on Outcomes. AB - Objective To characterize current vestibular schwannoma (VS) surgery outcomes with a nationwide database and identify factors associated with increased complications and prolonged hospital course. Study Design Retrospective review utilizing the University HealthSystem Consortium national inpatient database. Setting US academic health centers. Subjects and Methods Data from patients undergoing VS surgery were analyzed over a 3-year time span (October 2012 to September 2015). Surgical outcomes, such as length of stay (LOS), complications, and mortality, were analyzed on the basis of race, sex, age, and comorbidities during the 30-day postoperative period. Results A total of 3697 VS surgical cases were identified. The overall mortality rate was 0.38%, and the overall complication rate was 5.3%. Advanced age significantly affected intensive care unit LOS, mortality, and complications ( P = .04). Comorbidities, including hypertension, obesity, and depression, also significantly increased complication rates ( P = .02). Sixty-eight patients (1.8%) had a history of irradiation, and they had a significantly increased LOS ( P = .03). Conclusion Modern VS surgery has a low mortality rate and a relatively low rate of complications. Several factors contribute to high complication rates, including age and comorbidities. These data will help providers in counseling patients on which treatment course might be best suited for them. PMID- 29584555 TI - Gut microbiota as a source of novel antimicrobials. AB - Bacteria, Archaea, Eukarya and viruses coexist in the human gut, and this coexistence is functionally balanced by symbiotic or antagonistic relationships. Antagonism is often characterized by the production of antimicrobials against other organisms occupying the same environmental niche. Indeed, close co evolution in the gut has led to the development of specialized antimicrobials, which is attracting increased attention as these may serve as novel alternatives to antibiotics and thereby help to address the global problem of antimicrobial resistance. The gastrointestinal (GI) tract is especially suitable for finding novel antimicrobials due to the vast array of microbes that inhabit it, and a considerable number of antimicrobial producers of both wide and narrow spectrum have been described. In this review, we summarize some of the antimicrobial compounds that are produced by bacteria isolated from the gut environment, with a special focus on bacteriocins. We also evaluate the potential therapeutic application of these compounds to maintain homeostasis in the gut and the biocontrol of pathogenic bacteria.

AB - This article describes a holistic theoretical framework that can be used to explain intellectual disability (ID) and organize relevant information into a usable roadmap to guide understanding and application. Developing the framework involved analyzing the four current perspectives on ID and synthesizing this information into a holistic theoretical framework. Practices consistent with the framework are described, and examples are provided of how multiple stakeholders can apply the framework. The article concludes with a discussion of the advantages and implications of a holistic theoretical approach to ID. PMID- 29584559 TI - Health Services Use and Costs for Americans With Intellectual and Developmental Disabilities: A National Analysis. AB - Health services and associated costs for adults with intellectual and developmental disabilities (IDD) were nationally profiled and the predictors of high expense users statistically modeled. Using linked data from the National Health Interview Survey and Medical Expenditure Panel Survey for the years 2002 through 2011, the study found a mixed pattern of differences in rates of service use and costs when compared to the general population depending upon personal characteristics, health status, and type of health care service. Prescription medication costs were the primary driver of total health care expenditures for Americans with IDD. The presence of secondary chronic health conditions and poor mental health status were the consistent predictors of high expense users across types of health care. Study results are discussed in terms of implications for more nuanced evaluations of health care costs and need for recurring surveillance of health care for Americans with IDD in the years following passage of the Patient Protection and Affordable Care Act. PMID- 29584560 TI - Impact of Medicaid Managed Care on Illinois's Acute Health Services Expenditures for Adults With Intellectual and Developmental Disabilities. AB - States have increasingly transitioned Medicaid enrollees with disabilities from fee-for-service (FFS) to Medicaid Managed Care (MMC), intending to reduce state Medicaid spending and to provide better access to health services. Yet, previous studies on the impact of MMC are limited and findings are inconsistent. We analyzed the impact of MMC on costs by tracking Illinois's Medicaid acute health services expenditures for adults with intellectual and developmental disabilities (IDD) living in the community ( n = 1,216) before and after their transition to MMC. Results of the difference-in-differences (DID) regression analysis using an inverse propensity score weight (IPW) matched comparison group ( n = 1,134) design suggest that there were no significant state Medicaid cost savings in transitioning people with IDD from FFS to MMC. PMID- 29584562 TI - Identifying the Correlates and Barriers of Future Planning Among Parents of Individuals With Intellectual and Developmental Disabilities. AB - Although individuals with intellectual and developmental disabilities (IDD) are living longer lives, fewer than half of parents of individuals with IDD conduct future planning. The correlates and barriers to future planning must be identified to develop targeted interventions to facilitate future planning. In this study, 388 parents of individuals with IDD responded to a national, web based survey. Participants who were older, more educated, attended more parent training and support activities, and had children with fewer functional abilities, were more likely to engage in future planning. Reported barriers to future planning included: (a) lack of available services, (b) financial challenges, (c) reluctance of family members, (d) lack of time, (e) the emotional nature of future planning, (f) inertia, and (g) a lack of family members to be caregivers. Implications for policy, practice, and future research are discussed. PMID- 29584563 TI - Adverse Childhood Experiences Among Direct Support Professionals. AB - Direct support professionals (DSPs) provide integral support to many individuals with intellectual and developmental disabilities (IDD). Yet, individuals' access to qualified DSPs is often compromised as organizations struggle to hire and retain DSPs. Despite a vast body of research exploring factors associated with turnover, adverse childhood experiences (ACEs) among DSPs remain absent from the literature. ACEs encompass abuse and familial dysfunction prior to the age of 18 and, in the general population, have been linked to compromised well-being and work-related challenges in adult life. An online survey was conducted to explore the prevalence of ACE categories and ACE scores (i.e., the sum of each ACE category experienced by a person) among DSPs ( n = 386) working in licensed settings. Seventy-five percent of DSPs experienced at least one ACE and 30% had an ACE score of four or more. DSPs who identified as female and those who had been in their position less than one year had significantly higher ACE scores than males and others who had been in their position longer, respectively. In comparison with other studies, the four most common ACE categories among DSPs (i.e., divorce, emotional abuse, mental illness, and substance abuse) were the same, however, DSPs in the present study had a higher average ACE score and nearly twice the percentage of persons having an ACE score of four or more. The potential implications of ACEs among DSPs, at the intersection of their work with individuals with IDD, are discussed. PMID- 29584564 TI - Association Between MICA Gene Variants and the Risk of Hepatitis C Virus-Induced Hepatocellular Cancer in a Sicilian Population Sample. AB - There are currently no biomarkers that predict hepatocellular carcinoma (HCC) risk in patients with hepatitis C virus (HCV)-related cirrhosis. We investigated the relationships among major histocompatibility complex (MHC) class I chain related gene A (MICA) polymorphisms, plasma levels of soluble MICA (sMICA), and HCC risk in patients with HCV-related HCC. One hundred fifty-four HCV-related HCC patients, 93 HCV-related liver cirrhosis (LC) cases, and 244 healthy controls, all sampled from the native Sicilian population, were genotyped using the KASPTM single-nucleotide polymorphism genotyping method. The MICA rs2596542 polymorphism showed that the G/G genotype was significantly more frequent in HCC than control subjects and LC patients (p < 0.005). For MICA rs2596538 polymorphism, the C allele and C/C genotype were significantly more frequent in HCC than in controls and LC cases (p < 0.005), after controlling for potential confounders. These results demonstrate that MICA rs2596542G/G, and particularly the rs2596538C/C polymorphism, are associated with the risk of developing HCV-related HCC in a Sicilian population sample. Importantly, using a machine learning classifier, we found that "age" and either rs2596542 or rs2596538 were important discriminating factors for patients with LC and HCC. Finally, sMICA levels significantly increased during HCV-related liver disease progression, while a significant relationship between both rs2596542 and rs2596538 genotypes and sMICA plasma levels was identified in patients with LC and HCC. In summary, the MICA rs2596538 and rs2596542 variants warrant further research for their clinical validity and utility in relationship to the risk of developing HCV-related HCC in independent populations. PMID- 29584565 TI - Neisseria meningitidis serogroup B carriage by adolescents and young adults living in Milan, Italy: Prevalence of strains potentially covered by the presently available meningococcal B vaccines. AB - Recently, two vaccines against meningococcal serogroup B (MenB) have been developed. They are prepared according to the reverse vaccinology approach and contain 4 (4CMenB) and 2 (MenB-FHbp) cross-reactive surface proteins. In Italy 4CMenB vaccine has been included in the official vaccination schedule only recently and recommended only for infants and toddlers, whereas MenB-FHbp is not licensed. In order to collect information about the present carriage of Neisseria meningitidis serogroup B (MenB) in Italian adolescents and to evaluate the potential protection offered by the presently available MenB vaccines, 2,560 otherwise healthy, high school students aged 14-21 years (907 males, 35.4%, median age 16.2 years) were enrolled in Milan, Italy. A swab to collect posterior pharynx secretions was collected from each subject and meningococcal identification, serogrouping, multilocus sequence typing analysis, sequence alignments and phylogenetic analysis were performed. A total of 135 (5.3%) adolescents were meningococcal carriers. Strains belonging to serogroup B were the most common (n = 58; 2.3%), followed by MenY (n = 32; 1.2%), MenC (n = 7; 0.3%), MenW (n = 6; 0.3%) and MenX (n = 5; 0.2%). The remaining bacteria were not capsulated. The identified MenB strains belonged to eleven clonal complexes (CCs): ST-162 CC (n = 12; 20.7%), ST-865 CC (n = 12; 20.7%), ST-41/44/Lin.3 CC (n = 11; 19.0%), ST-35 CC (n = 6; 10.3%), ST-32/ET-5 CC (n = 4; 6.9%), ST-269 CC (n = 3; 5.2%), ST-213 CC (n = 2; 3.4%), ST-198 CC (n = 1; 1.7%), ST-461 CC (n = 1; 1.7%), ST-549 CC (n = 1; 1.7%), and ST-750 CC (n = 1; 1.7%). This study showed that MenB was the most commonly carried meningococcal serogroup found in adolescents living in Milan, Italy. The MenB vaccines presently licensed could have theoretically induced the production of antibodies effective against the greatest part of the identified MenB strains (100% in the case of 4CMenB and 95% in case of MenB-FHbp) Monitoring carriage remains essential to evaluate MenB circulation, but further studies are necessary to evaluate the effect on carriage and the final efficacy of both new MenB vaccines. PMID- 29584566 TI - Time, Resident Involvement, and Supply Drive Cost Variability in Septoplasty with Turbinate Reduction. AB - Objective To determine factors that influence cost variability in septoplasty with inferior turbinate reduction. Study Design Case series with chart review. Setting Tertiary care hospital and affiliated ambulatory surgical center. Subjects and Methods Surgical costs were reviewed for adult patients undergoing septoplasty with inferior turbinate reduction between December 2014 and September 2017. Cases where additional procedures were performed were excluded. Operative supply costs, operative time, room time, and resident involvement were determined. Contribution of these factors to total costs and variability were analyzed. Results The study included 116 patients (mean age, 38 years) and 4 faculty surgeons. Total cost was primarily driven by operative time (74%), with a smaller portion of total cost arising from supplies (26%). Time cost ( P < .0001) and supply cost ( P = .006) varied significantly among surgeons. A resident was involved in 46.6% of cases. When subanalyzed by resident year, no-resident and senior resident (postgraduate years 4 and 5) cases had nearly identical mean times, while junior resident (postgraduate years 1-3) cases had mean times and operative time costs that were 39% greater ( P < .001). Conclusion For septoplasty with inferior turbinate reduction, the greatest driver of cost variation was operative time. Resident involvement correlated with increased time and cost. Supply costs had a much smaller impact. When subanalyzed by resident year, junior resident-involved cases were significantly longer than no-resident cases. PMID- 29584567 TI - Preliminary clinical application of an aromatase inhibitor and a gonadotropin releasing hormone agonist combination for inoperable endometrial cancer patients with comorbidities: case report and literature review. AB - BACKGROUND: Endometrial cancer (EC) occurs most commonly after menopause. A proportion of patients present with advanced age and comorbidities, and become ineligible for surgery. The optimal treatment strategy of these patients remains a clinical challenge. Aromatase inhibitor (AI) combined with Gonadotropin releasing hormone agonist (GnRH-a) possesses profound effect in suppressing the estrogen level, has become a valid treatment in the breast cancer. However, the combined use of an AI and a GnRH-a in EC has rarely been studied. CASE PRESENTATION: Herein, we report the combination of an AI and a GnRH-a in the treatment of three patients with advanced age or comorbidities who were ineligible for surgery. The disease remained stable for two years in patients who received the combination treatment as an initial approach without any adverse effects. Moreover, an AI combined with a GnRH-a also effective as salvage treatment of recurrent patients. Further, we provide a brief review of the literature. CONCLUSION: The combination of an AI and a GnRH-a presents satisfactory therapeutic effect and provides an optimal option for inoperable EC patients. PMID- 29584568 TI - High Prevalence of CTX-M-15-Type Extended-Spectrum beta-Lactamase Among AmpC beta Lactamase-Producing Klebsiella pneumoniae Isolates Causing Bacteremia in Korea. AB - We investigated the antimicrobial susceptibility, the genotypic distributions of extended-spectrum beta-lactamase (ESBL) and AmpC genes, and the molecular epidemiology of AmpC-producing Klebsiella pneumoniae (AmpC-KP) isolates causing bacteremia. Among 260 K. pneumoniae clinical isolates included in this study, plasmid-mediated AmpC beta-lactamases were found in 20.7% (54/260), which included DHA-1 (96.3%, 52/54), CMY-2 (3.7%, 2/54), and CMY-10 (1.9%, 1/54). One isolate also produced DHA-1 along with CMY-2. Of the 54 AmpC-KP isolates, 31 isolates (57.4%) showed ESBL positivity. Of these 31 isolates with coproduction of ESBL and AmpC beta-lactamases, 25 isolates (80.6%) produced CTX-M-15 in addition to DHA-1. Nine isolates (29.0%) were nonsusceptible to imipenem. The most prevalent sequence type (ST) was ST11 (n = 31, 57.4%), followed by ST2361 (n = 5, 9.3%), which was newly identified in this study, and ST48 (n = 4, 7.4%). K. pneumoniae isolates coproducing DHA-1 and CTX-M-15 have emerged and disseminated in Korean hospitals, even in blood isolates causing bacteremia. Such infections may become a challenge for clinicians because there is a severely restricted range of available therapeutic options for these pathogens. PMID- 29584569 TI - Setting the stage for the review of the international estimate of short-term intake (IESTI) equation. AB - In the framework of setting Maximum Residue Limits (MRLs) for pesticides, both chronic and acute health risks to consumers arising from the long-term and short term dietary exposure to pesticide residues have to be assessed. The current internationally harmonized approach for assessing the acute dietary exposure is based on deterministic methods for calculating the IESTI (International Estimate of Short-Term Intake). Recently, it became apparent that the IESTI approach needs a revision in the light of new scientific and political aspects. The main reasons that require this review were the lack of an international harmonization of the methodology which implies trade barriers as well as difficulties in risk communication concerning the public trust in regulatory systems. The most recent milestone in the scientific debate on a possible revision of the IESTI equation was an international scientific workshop held in Geneva in September 2015. The main objectives of this meeting were the re-evaluation, and where possible, the international harmonization of the input parameters for the IESTI equations as well as the equations themselves. The main recommendations from the workshop were (i) to replace the highest residue and supervised trials median residue with the maximum residue limit (MRL), (ii) to use a standard variability factor of three, (iii) to derive the P97.5 large portion value from the distribution of consumption values of dietary surveys expressed as kg food/kg bw/d, and (iv) to remove the commodity unit weight from the equations. In addition, the application of conversion factors and processing factors was addressed. On the initiative of the (World Health Organization) WHO Collaborating Centre on Chemical Food Safety at the National Institute for Public Health and the Environment (RIVM), the Netherlands, an international working group with members from the French Agency for Food, Environmental and Occupational Health and Safety, France (ANSES), Australian Pesticides and Veterinary Medicines Authority, Australia (APVMA), German Federal Institute for Risk Assessment, Germany (BfR), Chemical Regulation Division, the United Kingdom (CRD), European Food Safety Authority (EFSA), and RIVM, the Netherlands was formed after the IESTI workshop to conduct a comprehensive impact assessment of the proposed changes of the IESTI equations. PMID- 29584570 TI - Factors affecting the quantitative uncertainty of the estimated short-term intake. Part II-Practical examples. AB - The effects of the spread of residue concentrations in the samples derived from the selected supervised trials and the number of trials were studied on the magnitude and uncertainty of the short-term dietary intakes calculated with the proposed new procedure (IESTIp) and that one used currently by the FAO (Food and Agriculture Organization) and WHO (World Health Organization) Joint meeting on Pesticide Residues (JMPR) (IESTIc). The residue data of 10 pesticides were obtained from supervised trials conducted on apples and pears. The methods described in Part I were used for the calculations of the uncertainty. The results indicate that the ratio of IESTIP to IESTIc (phiIESTI) is directly proportional to the ratio of the estimated maximum residue level (MRL), recommended by the JMPR; to the highest residue (HR) observed in supervised trials, and it may have a wide range depending on the particular conditions. The phiIESTI becomes greater with the increase of the difference between the mrl or maximum residue limit (MRL, established by the Codex Alimentarius Commission, CAC) and HR, and becomes smaller if the difference between the large portion (LP) and unit mass (U) decreases. The phiIESTI ranged between 2 and 5.1 in the 16 cases examined indicating that the IESTIp calculation method leads to higher intake estimates. The ratio of CVIESTIp and CVIESTIc ranged typically between 0.62 and 1.71. It rapidly increased up to 12 trials. For a larger number of trials, the ratio remained practically constant (1.69-1.71). The processing factor (PF) equally affects the MRL and HR values, therefore, it will not practically influence the phiIESTI. The uncertainty of the estimated median residues depends on the spread and number of values in the residue datasets, which affects the uncertainty of the conversion factor (CF) and subsequently the uncertainty of the estimated IESTIp. Residue values obtained from minimum nine independent trials are required for the correct calculation of the 95% confidence intervals of the calculated median residues. The uncertainty of the analytical results directly affects the median, HR values and indirectly the calculated mrl and the MRL derived from it. Therefore, it should also be considered for the calculation of the combined uncertainty of the conversion factors. For the correct interpretation of the results of dietary exposure calculations, the upper 95% confidence limit of the short-term intake should also be considered. However, it is not the current practice of regulatory agencies or JMPR. PMID- 29584571 TI - Factors affecting the quantitative uncertainty of the estimated short-term intake. Part I-Calculation methods. AB - The calculation of the combined uncertainty of the international estimated short term intake (IESTI) of ethephon residues in apples is shown as an example. The ethephon residues in apples were reported by the Joint FAO (Food and Agriculture Organization of the United Nations)/WHO (World Health Organization) Meeting on Pesticide Residues (JMPR). The apple consumption data were taken from the IESTI (international short-term intake) calculation template used by the JMPR. The IESTI was calculated with the currently used method (case 2a) and a proposed one recommended by the EFSA (European Food Safety Authority)/RIVM (Dutch National Institute for Public Health) Scientific Workshop co-sponsored by FAO and WHO. In this example, the ratio of IESTIproposed/IESTIcurrent and their combined relative uncertainty are about 2.8, and 1.7, respectively. The larger IESTI and uncertainty obtained with the proposed equation are the consequence of calculation only with the large portion (LP) instead of its combination with unit mass, and the MRL instead of the highest residue (HR). The LP is the major contributor to the combined uncertainty. Both the calculated IESTI and its combined uncertainty depend on the actual food - pesticide residue combination, and should be calculated for each case. PMID- 29584572 TI - Foreword. PMID- 29584573 TI - Impact of a proposed revision of the IESTI equation on the acute risk assessment conducted when setting maximum residue levels (MRLs) in the European Union (EU): A case study. AB - Proposals to update the methodology for the international estimated short-term intake (IESTI) equations were made during an international workshop held in Geneva in 2015. Changes to several parameters of the current four IESTI equations (cases 1, 2a, 2b, and 3) were proposed. In this study, the overall impact of these proposed changes on estimates of short-term exposure was studied using the large portion data available in the European Food Safety Authority PRIMo model and the residue data submitted in the framework of the European Maximum Residue Levels (MRL) review under Article 12 of Regulation (EC) No 396/2005. Evaluation of consumer exposure using the current and proposed equations resulted in substantial differences in the exposure estimates; however, there were no significant changes regarding the number of accepted MRLs. For the different IESTI cases, the median ratio of the new versus the current equation is 1.1 for case 1, 1.4 for case 2a, 0.75 for case 2b, and 1 for case 3. The impact, expressed as a shift in the IESTI distribution profile, indicated that the 95th percentile IESTI shifted from 50% of the acute reference dose (ARfD) with the current equations to 65% of the ARfD with the proposed equations. This IESTI increase resulted in the loss of 1.2% of the MRLs (37 out of 3110) tested within this study. At the same time, the proposed equations would have allowed 0.4% of the MRLs (14 out of 3110) that were rejected with the current equations to be accepted. The commodity groups that were most impacted by these modifications are solanacea (e.g., potato, eggplant), lettuces, pulses (dry), leafy brassica (e.g., kale, Chinese cabbage), and pome fruits. The active substances that were most affected were fluazifop-p-butyl, deltamethrin, and lambda-cyhalothrin. PMID- 29584574 TI - Effect of individual parameter changes on the outcome of the estimated short-term dietary exposure to pesticides. AB - In 2015 a scientific workshop was held in Geneva, where updating the International Estimate of Short-Term Intake (IESTI) equations was suggested. This paper studies the effects of the proposed changes in residue inputs, large portions, variability factors and unit weights on the overall short-term dietary exposure estimate. Depending on the IESTI case equation, a median increase in estimated overall exposure by a factor of 1.0-6.8 was observed when the current IESTI equations are replaced by the proposed IESTI equations. The highest increase in the estimated exposure arises from the replacement of the median residue (STMR) by the maximum residue limit (MRL) for bulked and blended commodities (case 3 equations). The change in large portion parameter does not have a significant impact on the estimated exposure. The use of large portions derived from the general population covering all age groups and bodyweights should be avoided when large portions are not expressed on an individual bodyweight basis. Replacement of the highest residue (HR) by the MRL and removal of the unit weight each increase the estimated exposure for small-, medium- and large-sized commodities (case 1, case 2a or case 2b equations). However, within the EU framework lowering of the variability factor from 7 or 5 to 3 counterbalances the effect of changes in other parameters, resulting in an estimated overall exposure change for the EU situation of a factor of 0.87-1.7 and 0.6-1.4 for IESTI case 2a and case 2b equations, respectively. PMID- 29584575 TI - Impact of proposed changes in IESTI equations for short-term dietary exposure to pesticides from Australian and Codex perspective. AB - In 2015 a scientific workshop was held in Geneva, where updating the four equations for estimating the short-term dietary exposure (International Estimated Short Term Intake, IESTI) to pesticides was suggested. The impact of these proposed changes on the exposure was studied by using residue data and large portion consumption data from Codex and Australia. For the Codex data, the exposure increased by a median factor of 2.5 per commodity when changing to the proposed IESTI equations. The increase in exposure was highest for bulked and blended food commodities (case 3 equations), followed by medium-sized food commodities (case 2a equations) and small- and large-sized food commodities (case 1 and case 2b equations). For the Australian data, out of 184 maximum residue limit (MRL) large portion combinations showing acute exposures below the acute reference dose (ARfD) with the current IESTI equations, 23 exceeded the ARfD with the proposed IESTI equations (12%). The percentage exceeding the ARfD was higher for the Australian MRL large portion combinations (12% of 184) than for those of Codex (1.3% of 8,366). However, the percentage MRL loss in the Australian dataset may not be representative of all pesticide MRLs since it concerns six pesticides only, specifically selected to elucidate the potential effects of the use of the proposed IESTI equations. For the Codex data, the increase in exposure using the proposed equations resulted in a small increased loss of 2.6% of the 1,110 MRLs estimated by the Joint FAO/WHO Meeting on Pesticide Residues (JMPR): 1.4% of the MRLs were already not acceptable with the current equations, 4.0% of the MRLs were not acceptable with the newly proposed equations. Our study revealed that case 3 commodities may be impacted more by the proposed changes than other commodities. This substantiates one of the conclusions of the Geneva workshop to gather information on bulking and blending practices in order to refine MRL setting and dietary risk assessment for case 3 commodities where possible. PMID- 29584576 TI - Improvements of Shooting Performance in Adolescent Air Rifle Athletes After a 6 week Balance and Respiration Training Programs. AB - CONTEXT: Several factors, such as balance and respiration training programs, have been identified as contributing to the establishment of a shooting performance. However, little is known about the benefits of these programs on the shooting record, among adolescent air rifle athletes. OBJECTIVE: To determine whether there is a gain in the shooting record, among adolescent air rifle athletes, after participation in balance and respiration training programs. DESIGN: Case control study. SETTING: Shooting range. PARTICIPANTS: Twenty-one adolescent air rifle athletes were recruited from the local school community and assigned to an experimental (n=11; EG) or control (n=10; CG) group. INTERVENTION: The EG performed respiration and balance training for 30 min, three times a week for 6 weeks, and the CG performed balance training only. MAIN OUTCOME MEASURES: Data were collected on the respiratory function, muscle activity, and shooting record, before and after the 6-week intervention. RESULTS: The forced vital capacity (FVC), forced expired volume in one second (FEV1), FEV1 as a percentage of FVC (FEV1/FVC), peak expiratory flow (PEF), and maximum voluntary ventilation (MVV) were significantly increased in the EG, and FEV1/FVC was significantly increased in the CG (p<0.05). The FVC and PEF, post-intervention, were significantly different between the groups (p<0.05). The activity of the right internal oblique (RTIO) and left internal oblique (LTIO) muscles of the FVC were significantly different in the EG (p<0.05). Within group changes in right external oblique (EO), RTIO, and LTIO of the MVV were significantly increased in the EG (p<0.05). The RTIO and LTIO activity improved more significantly in the EG than CG (p<0.05). There was no difference between the groups with respect to the shooting records. CONCLUSIONS: The experiment demonstrates that the balance and respiration training programs may help improve the respiratory function and muscle activity other than the shooting record. PMID- 29584578 TI - Longitudinal Associations of Metabolic Syndrome Severity Between Childhood and Young Adulthood: The Bogalusa Heart Study. AB - BACKGROUND: Childhood metabolic syndrome (MetS) is associated with insulin resistance and increased risk for later development of type 2 diabetes (T2DM) and cardiovascular disease (CVD). In using MetS severity z-scores, our objective was to assess longitudinal associations in MetS severity, fasting insulin levels as a sign of insulin resistance and risk for T2DM, and uric acid levels as a biomarker of oxidative stress leading to CVD. METHODS: We used linear regression to analyze longitudinal data from 285 white and black participants from the Bogalusa Heart Study evaluated at baseline at ages 5-19 and as young adults after a mean of 12.0 years follow-up. We assessed correlations between childhood MetS severity and young-adult MetS severity, fasting insulin, and uric acid levels, both overall and by sex- and racial subgroups. RESULTS: Overall, childhood MetS z-scores were positively associated with young-adult MetS z-scores (r = 0.52), insulin (r = 0.34), and uric acid (r = 0.28) (all P < 0.001). These associations were consistent across all sex- and racial subgroups, except for young adult uric acid in white males in which childhood MetS-z was not associated (r = 0.15, P = 0.243). There was a strong cross-sectional association of young-adult MetS z scores with insulin (r = 0.70) and uric acid (r = 0.57) (both P < 0.001), which was consistent for all sex- and racial subgroups. CONCLUSIONS: These positive longitudinal correlations between childhood MetS z-scores and markers of later insulin resistance and oxidative stress suggest long-term durability of risk for CVD and T2DM. This suggests potential for MetS severity to serve as an indicator to monitor for future risk of T2DM and CVD. PMID- 29584579 TI - Prevalence of Pyrazinamide Resistance in Khyber Pakhtunkhwa, Pakistan. AB - AIMS: Pyrazinamide (PZA) is an important component of first-line tuberculosis (TB) treatment because of its distinctive capability to kill subpopulations of persister Mycobacterium tuberculosis (MTB). The significance of PZA can be understood by its inclusion in the most recent World Health Organization recommended multidrug-resistant (MDR) TB regimen. Very little information is available about the prevalence of PZA-resistant TB from geographically distinct regions of high burden countries, including Khyber Pakhtunkhwa (KPK), Pakistan, because drug susceptibility testing (DST) of PZA is not regularly performed due to the complexity. In this study, we aimed to find the prevalence of PZA resistance in geographically distinct, Pashtun-dominant KPK Province of Pakistan and its correlation with other first- and second-line drug resistance. MATERIALS AND METHODS: In this study, DST of PZA was performed through an automated BACTEC MGIT 960 system (BD Diagnostic Systems). The resistant samples were further subjected to DST of isoniazid (INH), rifampicin (RIF), ethambutol (EMB), streptomycin (SM), moxicillin (MOX), amikacin (AMK), ofloxacin (OFX), kanamycin (KM), and capreomycin (CAP). RESULTS: Out of 1,075 MTB-positive isolates, 83 (7.7%) were found to be resistant to PZA. Among the PZA-resistant isolates, 76 (90-91.6%) and 67 (80-80.7%) were found to be resistant to INH and RIF, respectively, whereas 63 (76%) were resistant to both first-line drugs, INH and RIF (MDR-TB). The resistance level of EMB, OFX, and SM was also significantly high in PZA resistance, 35 (42%), 40 (48%), and 41 (49-50%) respectively. CONCLUSION: PZA resistance is significantly associated with other first- and second-line drug resistance. A significant number of PZA-resistant isolates are MDR cases. Therefore, DST of PZA should regularly be performed along with other drugs for better management of treatment of MDR and extensively drug resistant (XDR), to avoid side effects in patients.

AB - Biobanks are infrastructures for large-scale biology innovation. Governance of biobanks can be usefully informed by studies of publication trends, for example, on the types of biosamples employed in scientific publications. We examined trends in each of the serum, plasma, peripheral blood mononuclear cell (PBMC), buffy coat, tissue, and gut microbiome biosample-related scientific publications over the past 40 years, using data between 1977 and 2016 from the Scopus database. We found that the number of tissue-related publications was the highest in each year of our analysis than other biosamples, but was generally less than the sum of serum- and plasma-related publications. Importantly, the microbiome publications increased greatly starting in the 2010s, and currently overtook the number of publications on PBMC and buffy coat. Among serum-, plasma-, and tissue related publications, the number of protein- and RNA-related publications was generally higher than cell-free DNA-, DNA-, and metabolite-related publications for the past 40 years. Mass spectrometry- and next-generation sequencing-related publications have increased dramatically since the 2000s and 2010s, respectively. Microbiome- and metabolite-related biosamples can help diversify future biosample collections, while tissue collections appear to maintain their importance in scientific publications. We also report here our observations on the countries that use biosample research (e.g., China, United Kingdom, United States, and others). These publication trends by the type of biosamples illuminate roadmaps by which biobanks might establish and diversify their biosample collections in the future. In addition, we note that biobanks need to secure biosamples appropriate for integrated analysis of multi-omics research data. PMID- 29584580 TI - Differences in Timed Up and Go Subtasks Between Older People With Mild Cognitive Impairment and Mild Alzheimer's Disease. AB - This study compared performances of timed up and go test subtasks between 40 older people with preserved cognition, 40 with mild cognitive impairment, and 38 with mild Alzheimer's disease. The assessment consisted of anamneses and timed up and go test subtasks (sit-to-stand, walking forward, turn, walking back, and turn to-sit). Data were captured by Qualisys Track Manager software and processed by Visual3D software. The MATLAB program was applied to detect and analyze timed up and go test subtasks. All subtasks differentiated people with Alzheimer's disease and preserved cognition, except the sit-to-stand subtask, which did not distinguish any group. The walking forward subtask differed older people with preserved cognition from mild cognitive impairment, specifically on minimum peak of knee, average value of knee, and hip (pitch axis) during stance phase. The walking back, turn, and turn-to-sit subtasks distinguished subjects with Alzheimer's disease from mild cognitive impairment. The separated analysis of transition and walking subtasks is important in identifying mobility patterns among cognitive profiles.

AB - This genomics global governance research study presents the dynamics and the evolving nature of salient challenges that global genomics initiatives encounter in designing new models for data management, exchange, and collaboration across disciplines, sectors, and countries. Using a multiple case study approach, we assessed and compared organizational responses across diverse genomics initiatives. The richness of a comparative qualitative analysis clearly shows the complexity addressed by genomics initiatives and, importantly, expands current studies by moving beyond an open versus property regime dichotomy. Although we identify some common themes, fundamental differences emerge in the way genomics initiatives set goals, manage heterogeneity, define resources, devise governance, and enable data sharing. Such differences demonstrate the ongoing processes of adapting governance structures, management processes, and organizational design solutions that are implemented in response to different social, technical, and policy environments. We find that genomics initiatives largely benefit from and are shaped by the engagement with large communities of scientists to rethink and design shared rules and guidelines for data exchange and use. Our study provides direct guidance to future global genomics initiatives, but it also offers a benchmark for research in the omics field broadly, both in terms of design and methodological approaches to understand the emerging forms of scientific governance and innovation ecosystems. PMID- 29584583 TI - Involvement of the SnRK1 subunit KIN10 in sucrose-induced hypocotyl elongation. AB - A mechanism participating in energy sensing and signalling in plants involves the regulation of sucrose non-fermenting1 (Snf1)-related protein kinase 1 (SnRK1) activity in response to sugar availability. SnRK1 is thought to regulate the activity of both metabolic enzymes and transcription factors in response to changes in energy availability, with trehalose-6-phospate functioning as a signalling sugar that suppresses SnRK1 activity under sugar-replete conditions. Sucrose supplementation increases the elongation of hypocotyls of developing Arabidopsis seedlings, and this response to sucrose involves both the SnRK1 subunit KIN10 and also TREHALOSE-6-PHOSPHATE SYNTHASE1 (TPS1). Here, we measured sucrose-induced hypocotyl elongation in two insertional mutants of KIN10 (akin10 and akin10-2). Under short photoperiods, sucrose supplementation caused great proportional hypocotyl elongation in these KIN10 mutants compared with the wild type, and these mutants had shorter hypocotyls than the wild type in the absence of sucrose supplementation. One interpretation is that SnRK1 activity might suppress hypocotyl elongation in the presence of sucrose, because KIN10 overexpression inhibits sucrose-induced hypocotyl elongation and akin10 mutants enhance sucrose-induced hypocotyl elongation. PMID- 29584584 TI - Adsorption behaviours and mechanisms of heavy metal ions' impact on municipal waste composts with different degree of maturity. AB - Composting may change the adsorption characteristics and mechanisms of organic materials due to their differences in organic chemical functional groups and surface structures. The adsorption properties of heavy metals onto the municipal solid waste compost (MSW-C) and its secondary fermentation form (MSW-SC) were comparatively investigated in single, binary and multiple solutions by batch experiments. In the single-metal system, the maximum adsorption capacities of Cu, Zn, Cd and Ni onto MSW-SC were 29.2, 26.3, 38.1 and 22.0 mg g-1, respectively, and showed higher than that of MSW-C. The adsorption fitted best with the pseudo second-order kinetics and Langmuir isotherms. The competitive adsorption results indicated that the composts exhibited good selectivity in the adsorption of Cu over Cd, Zn and Ni; thus, for the quaternary-metal systems, the adsorption sequence was Cu > Zn > Cd > Ni. Humic acid content, cation exchange capacity and surface area were increased following the secondary composting. FTIR analysis indicated amine and aromatic compounds were main binding sites accounting for metal sorption. SEM-EDX analysis suggested that the MSW-SC had rough surfaces and stronger adsorption capacity. Decreasing percentage of exchangeable metals was found in the metal-loaded MSW-SC based on a speciation analysis. This study highlights the interactive impacts of different metals during adsorption by compost with different maturity, the secondary composting process was a multifunctional improvement of sorption characteristics and MSW-SC was developed to be a highly efficient biosorbent.

AB - Since the evolutionary discovery of RNA interference and its utilization for gene knockdown in mammalian cell, a remarkable progress has been achieved in small interfering RNA (siRNA) therapeutics. siRNA is a promising tool, utilized as therapeutic agent against various diseases. Despite its significant potential benefits, safe, efficient, and target oriented delivery of siRNA is one of the major challenges in siRNA therapeutics. This review covers major achievements in clinical trials and targeted delivery of siRNAs using various targeting ligand receptor pair. Local and systemically administered siRNA drug candidates at various phases in clinical trials are described in this review. This review also provides a deep insight in development of targeted delivery of siRNA. Various targeting ligand-siRNA pair with complexation and conjugation approaches are discussed in this review. This will help to achieve further optimization and development in targeted delivery of siRNAs to achieve higher gene silencing efficiency with lowest siRNA dose availability.

AB - To achieve high-temperature gasification-melting of combustible solid waste, ash melting behaviour under conditions simulating high-temperature gasification were studied. Raw ash (RA) and gasified ash (GA) were prepared respectively by waste ashing and fluidized bed gasification. Results of microstructure and composition of the two-ash indicated that GA showed a more porous structure and higher content of alkali and alkali earth metals among metallic elements. Higher temperature promoted GA melting and could reach a complete flowing state at about 1250 degrees C. The order of melting rate of GA under different atmospheres was reducing condition > inert condition > oxidizing condition, which might be related to different existing forms of iron during melting and different flux content with atmosphere. Compared to RA, GA showed lower melting activity at the same condition due to the existence of an unconverted carbon and hollow structure. The melting temperature for sufficient melting and separation of GA should be at least 1250 degrees C in this work. PMID- 29584587 TI - Behavioral Effects of Focal Irradiation in a Juvenile Murine Model. AB - Chemotherapy has been successfully used to reduce radiation dose and volume for most pediatric patients. However, because of the failure of chemotherapeutic agents to cross the blood-brain barrier and the lack of response of some brain tumors to these agents, radiation therapy is still used to treat many childhood cancers with CNS involvement. In this study, we investigated the radiation effects on cognition and dendritic structure in the hippocampus in juvenile male mice. Twenty-one-day-old male C57BL/6 mice were irradiated using the small animal radiation research platform (SARRP). Animals were exposed to either a 10 Gy single dose or 10 Gy * 2 fractionated doses of X-ray cranial radiation. Five weeks after irradiation, animals were tested for hippocampus-dependent cognitive performance in the Morris water maze. Significant impairment in spatial memory retention was observed in the probe trial after the first day of hidden-platform training (first probe trial) in animals that received either 10 Gy single-dose or 10 Gy * 2 fractionated doses. However, by day 5, mice that received a 10 Gy single dose showed spatial memory retention in the probe trials, whereas mice that received the 20 Gy fractionated doses remained impaired. During Y-maze testing, animals exposed to radiation were impaired; the irradiated mice were not able to distinguish among the three Y-maze arms and spent approximately the same amount of time in all three arms during the retention trial. Radiation significantly compromised the dendritic architecture and reduced spine density throughout the hippocampal trisynaptic network. PMID- 29584589 TI - Molecular Characterization and Phylogenetic Analysis of Anaplasma spp. and Ehrlichia spp. Isolated from Various Ticks in Southeastern and Northwestern Regions of Iran. AB - INTRODUCTION: Anaplasma/Ehrlichia species are tick-transmitted pathogens that cause infections in humans and numerous domestic and wild animal species. There is no information available on the molecular characteristics and phylogenetic position of Anaplasma/Ehrlichia spp. isolated from tick species from different geographic locations in Iran. The aim of this study was to determine the prevalence, molecular characteristics, and phylogenetic relationship of both Anaplasma spp. and Ehrlichia spp. in tick species isolated from different domestic animals from two different geographical locations of Iran. METHODS: A total of 930 ticks were collected from 93 cattle, 250 sheep, and 587 goats inhabiting the study areas. The collected ticks were then investigated for the presence of Anaplasma/Ehrlichia spp. using nested PCR based on the 16S rRNA gene, followed by sequencing. Sequence analysis was done based on the data published in the GenBank on Anaplasma/Ehrlichia spp. isolates using bioinformatic tools such as the standard nucleotide BLAST. RESULTS: Genome of Anaplasma or Ehrlichia spp. was detected in 14 ticks collected in Heris, including 5 Dermacentor marginatus, 1 Haemaphysalis erinacei, 3 Hyalomma anatolicum, and 4 Rhipicephalus sanguineus, also in 29 ticks collected in Chabahar, including 14 R. sanguineus, 8 D. marginatus, 3 Hyalomma Anatolicum, and 4 Hyalomma dromedarii. Partial analysis of the 16S rRNA gene sequence of positive samples collected from goats and sheep showed that they were infected with Anaplasma/Ehrlichia spp. that were 94-98% identical to ovine Anaplasma and 91-96% identical to Neoehrlichia and Ehrlichia spp. CONCLUSION: The various ticks identified in this study suggest the possible emergence of tick-borne diseases in animals and humans in these regions. R. sanguineus and D. marginatus seem to be predominant vectors responsible for anaplasmosis in these regions. Partial sequence analysis of the 16S rRNA gene showed that A. ovis is genetically polymorphic in these regions. Furthermore, an association between the genetic heterogeneity of this microorganism and the geographical regions of Anaplasma strains was found. This study also showed that those ticks that were collected from the same geographical origin were infected with closely related strains of Anaplasma.

AB - Squamous cell carcinomas of the head and neck are appearing with increased frequency in both marrow transplanted and non-transplanted Fanconi anemia (FA) patients. FA patients commonly display radiosensitivity of epithelial tissues, complicating effective radiotherapy. Fancd2-/- mice (C57BL/6J and 129/Sv background) demonstrate epithelial tissue sensitivity to single-fraction or fractionated irradiation to the head and neck and distant marrow suppression (abscopal effect), both ameliorated by intraoral administration of the mitochondrial-targeted antioxidant, GS-nitroxide, JP4-039. We now report that mice of two other FA genotypes, Fancg-/- (B6) and the most prevalent human genotype Fanca-/- (129/Sv), also demonstrate: 1. reduced longevity of hematopoiesis in long-term bone marrow cultures; 2. radiosensitivity of bone marrow stromal cell lines; and 3. head and neck radiation-induced severe mucositis and abscopal suppression of distant marrow hematopoiesis. Intraoral administration of JP4-039/F15, but not non-mitochondrial-targeted 4-amino Tempo/F15 or F15 alone, prior to each radiation treatment ameliorated both local and abscopal radiation effects. Head and neck irradiated TGF-beta-resistant SMAD3 /- (129/Sv) mice and double-knockout SMAD3-/- Fancd2-/- (129/Sv) mice treated daily with TGF-beta receptor antagonist, LY364947, still displayed abscopal bone marrow suppression, implicating a non-TGF-beta mechanism. Thus, amelioration of both local normal tissue radiosensitivity and distant marrow suppression by intraoral administration of JP4-039 in Fancg-/- and Fanca-/- mice supports a clinical trial of this locally administered normal tissue radioprotector and mitigator during head and neck irradiation in FA patients. PMID- 29584590 TI - Maternal Thyroid Function in Early Pregnancy and Child Neurodevelopmental Disorders: A Danish Nationwide Case-Cohort Study. AB - BACKGROUND: Maternal thyroid dysfunction may adversely affect fetal brain development, but more evidence is needed to refine this hypothesis. The aim of this study was to evaluate potential fetal programming by abnormal maternal thyroid function on child neurodevelopmental disorders. METHODS: The design was a case-cohort study within the Danish National Birth Cohort (1997-2003). From the eligible cohort of 71,706 women, a random 12% sub-cohort (n = 7624) was selected, and all women (n = 2276) whose child was diagnosed with seizures, specific developmental disorder (SDD), autism spectrum disorder (ASD), and/or attention deficit/hyperactivity disorder (ADHD) up to December 31, 2010, were identified. All women had a blood sample drawn in early pregnancy (median week 9), and the stored sample was used for measurement of free thyroxine and thyrotropin. Method- and week-specific reference ranges were used for classification of maternal thyroid function. A weighted Cox proportional hazards model was used to estimate adjusted hazard ratio (aHR) with 95% confidence intervals (CI) for neurodevelopmental disorders in children exposed to maternal thyroid dysfunction. RESULTS: The overall frequency of abnormal maternal thyroid function was 12.5% in the sub-cohort and significantly higher among cases of ASD (17.9%; aHR = 1.5 [CI 1.1-2.1]), but not among other types of neurodevelopmental disorders (febrile seizures: 12.7%; epilepsy: 13.1%; SDD: 12.6%; and ADHD: 14.0%). However, evaluation of subtypes of maternal thyroid dysfunction showed that maternal overt hypothyroidism (thyrotropin >10 mIU/L) was a risk factor for epilepsy in the child (aHR = 3.5 [CI 1.2-10]), as was overt hyperthyroidism for cases diagnosed within the first year of life (aHR = 3.0 [CI 1.03-8.4]). Furthermore, both maternal hypothyroidism (aHR = 1.8 [CI 1.1-2.7]) and overt hyperthyroidism (aHR = 2.2 [CI 1.1-4.4]) were risk factors for ASD in the child, and isolated low free thyroxine was associated with ASD (aHR = 4.9 [CI 2.03-11.9]) and ADHD (aHR = 2.3 [CI 1.2-4.3]) in girls but not in boys. CONCLUSIONS: Abnormal maternal thyroid function in early pregnancy was associated with epilepsy, ASD, and ADHD in the child, but associations differed by subtypes of exposure and by child age and sex. More evidence on subtypes and severity of maternal thyroid function is needed, and alternative outcomes of child neurodevelopment may be warranted.

VEGF polymorphisms are thought to modulate vascular endothelial growth factor plasma levels and therefore may be implicated in glioma risk. We aimed to clarify the role of VEGF and von Willebrand factor polymorphisms in glioma susceptibility and prognosis. A case-control study of 126 glioma patients and 180 cancer-free controls was performed. Using Sequenom MassARRAY platform, 11 VEGF and 1 VWF polymorphisms were genotyped. Unconditional multivariate logistic regression models were used to calculate odds ratios and 95% confidence intervals. The associations between polymorphisms and survival were evaluated using a Cox regression model. Bonferroni's adjustment was used to correct for multiple testing. The VEGF polymorphism rs833061 was strongly associated with increased risk for glioma (odds ratio = 164.85) and glioblastoma (odds ratio = 155.66), confirmed after Bonferroni correction. Also, the VEGF polymorphisms rs3024994, rs2010963, and particularly the homozygous carriers of rs1005230 were associated with a worse prognosis for glioma and glioblastoma. Our data support a role of VEGF and VWF polymorphisms as glioma biomarkers, with additional potential relevance for molecular stratification of patients for anti-angiogenic therapies.

AB - Purpose To compare the outcome of architectural distortion (AD) without associated mass only on digital breast tomosynthesis (DBT) with AD seen at two dimensional (2D) mammography and to evaluate if the incidence of malignancy is influenced by the presence of a correlate at ultrasonography (US). Materials and Methods This retrospective study had institutional review board approval and was HIPAA compliant. All consecutive cases in which patients with AD were ultimately assigned Breast Imaging Reporting and Data System (BI-RADS) 4 or 5 categories from 2009 to 2016 were reviewed by three readers for visibility (2D vs DBT). The level of suspicion was assigned using a Likert scale. Pathologic results were compared between 2D-detected and DBT-detected AD. Frequencies were compared by using the McNemar and Pearson chi2 exact tests. Results One hundred eighty-one AD lesions were included; 122 (67.4%) were 2D visible while 59 (32.6%) were DBT detected. Forty-two women (with 43 lesions) underwent 2D mammography prior to initiation of DBT. In 117 women with 121 AD lesions who underwent 2D mammography plus DBT, 59 lesions (48.8%) were detected only with DBT. The malignancy rate based on final pathology was significantly higher for 2D-detected AD (53 [43.4%] of 122) compared with DBT (six [10.2%] of 59) (P < .001). A US correlate was more frequent with 2D-detected AD (103 [84.4%] of 122) than DBT (33 [55.9%] of 59) (P < .001). Malignancy rate was not different for DBT-detected AD with (four [12.1%] of 33; 95% confidence interval [CI]: 3.4%, 28.2%]) or without (two [7.7%] of 26; 95% CI: 0.9%, 25.1%]) a US correlate. NPV based on radiologists' level of suspicion was high (91.8%-98.0%) but not sufficient enough to forgo biopsy. Conclusion DBT-detected suspicious AD has a lower malignancy outcome compared with 2D mammography-detected suspicious AD, although still high enough to warrant biopsy.

AB - Purpose To determine the performance of magnetic resonance (MR) imaging-based tumor metrics for evaluation of response to transarterial chemoembolization (TACE) in patients with unresectable intrahepatic cholangiocarcinoma (ICCA). Materials and Methods Ninety-four patients with unresectable ICCA underwent baseline and follow-up MR imaging after TACE and were followed up until death or end of study duration. Lesions were analyzed for anatomic (Response Evaluation Criteria in Solid Tumors [RECIST] and tumor volume) and functional (viable tumor volume, viable tumor burden, and apparent diffusion coefficient [ADC]) volumetric MR parameters by using semiautomatic software. Response was assessed by using changes in viable tumor volume by using modified RECIST (mRECIST)-derived thresholds (three-dimensional mRECIST), viable tumor burden, and ADC. Overall survival was the primary endpoint. Cox-regression and Kaplan-Meier survival analysis were used. Results Tumor volume did not change after TACE (P = .07) whereas RECIST diameter showed a small change (-2.6%; P = .02). There was an increase in ADC (20.7%) and a decrease in viable tumor volume (-29.3%) and viable tumor burden (-29.1%; P < .001 for all). Higher overall survival was noted among responders by using thresholds of 25% increase in ADC, 66% decrease in viable tumor volume, and 50% decrease in viable tumor burden (log-rank test, P < .05). Hazard ratio for nonresponders by using ADC, three-dimensional mRECIST, and viable tumor burden at multivariable analysis was 2.9 (P = .004), 4.1 (P = .009), and 4.0 (P = .002), respectively. Survival differences were noted for patients who showed response by using all three parameters (ADC, three-dimensional mRECIST, and viable tumor burden) versus those who showed response by using either one or two of these parameters versus those who showed no response (P < .001). Conclusion Changes in volumetric ADC, viable tumor volume, and viable tumor burden at MR imaging provide prognostic information among patients with unresectable ICCA who undergo TACE.

PMID- 29584594 TI - Acoustic Radiation Force Impulse US Imaging: Liver Stiffness in Patients with Chronic Hepatitis B with and without Antiviral Therapy. AB - Purpose To investigate the clinical utility and longitudinal change of acoustic radiation force impulse (ARFI) ultrasonographic (US) imaging in patients with chronic hepatitis B. Materials and Methods A retrospective cohort study of patients with chronic hepatitis B who underwent serial ARFI examinations in a tertiary referral center in Taiwan between 2012 and 2016 was conducted. The clinical information and noninvasive liver stiffness measurement tests (ARFI, Fibrosis-4 index [FIB-4], and FibroScan) were collected. Serial ARFI measurements were compared in patients without antiviral therapy (nontreatment group) and during antiviral therapy (treatment group). The linear mixed-effects model with random coefficients was used to compare longitudinal repeated measurements. Results A total of 559 patients undergoing serial ARFI examinations were included. The ARFI value correlated with FIB-4 (correlation coefficient = 0.55, P < .001) and FibroScan (correlation coefficient = 0.69, P < .001) results. There were 314 patients with five or more ARFI measurements in more than 3 years of follow-up. The ARFI value remained unchanged in the nontreatment group (n = 189, from 1.11 to 1.11 m/sec, time trend P = .911). However, the ARFI value declined significantly in the treatment group (n = 125, from 1.63 to 1.37 m/sec, time trend P < .001), both in patients with cirrhosis (n = 51, from 2.15 to 1.75 m/sec, time trend P < .001) and in those without (n = 74, from 1.27 to 1.11 m/sec, time trend P < .001). Conclusion ARFI US imaging is an important clinical noninvasive test for liver stiffness measurement and can be used for serial measurements in the management of chronic hepatitis B. Antiviral therapy significantly reduces liver stiffness during longitudinal follow-up. PMID- 29584596 TI - Estimating the Patient-specific Dose to the Thyroid and Breasts and Overall Risk in Chest CT When Using Organ-based Tube Current Modulation. AB - Purpose To assess the potential dose reduction to the thyroid and breasts in chest computed tomography (CT) with organ-based tube current modulation (OBTCM). Materials and Methods In this retrospective study (from January 2015 to December 2016), the location of the breasts with respect to the reduced tube current zone was determined. With Monte Carlo simulations, patient-specific dose distributions of chest CT scans were calculated for 50 female patients (mean age, 53.7 years +/ 17.5; range, 20-80 years). The potential dose reduction with OBTCM was assessed. In addition, simulations of clinical OBTCM scans were made for 17 of the 50 female patients (mean age, 43.8 years +/- 17.1; range, 20-69 years). Posterior organs in the field of view were analyzed and lifetime attributable risk (LAR) of cancer incidence and mortality was estimated. Image quality between standard CT and OBTCM scans was compared. Results No women had all breast tissue within the reduced tube current zone. Dose reductions of 18% in the thyroid and 9% in the breasts were observed, whereas the doses in lung, liver, and kidney were 17%, 11%, and 26% higher. Overall, the LAR for cancer incidence was not significantly different between conventional and OBTCM scanning (P = .06). Image quality improved with OBTCM (P < .002). Conclusion The potential benefit of OBTCM to the female breast in chest CT is overestimated because of a limited reduced tube current zone; despite a 9% dose reduction to the female breast, posterior organs will absorb up to 26% more radiation, resulting in no reduction in radiation induced malignancies.

AB - Purpose To determine whether texture features on pretreatment contrast material enhanced computed tomographic (CT) images can help predict overall survival (OS) and time to progression (TTP) in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. Materials and Methods This retrospective study included 92 patients with advanced HCC treated with sorafenib between January 2009 and April 2015 at two independent university hospitals. Sixty-four of the 92 patients (70%) (six women, 58 men; median age, 66 years) were included from institution 1 and constituted a training cohort; 28 patients (30%) (five women, 23 men; median age, 64 years) were included from institution 2 and constituted a validation cohort. Pretreatment CT texture analysis was performed on late arterial and portal venous phase HCC images. Mean gray-level intensity, entropy, kurtosis, skewness, and standard deviation values were derived from the pixel distribution histogram before and after spatial filtration at different anatomic scales ranging from fine to coarse texture. Lesion heterogeneity was also visually graded on a 4-point scale. Correlations between visual analysis and texture parameters were assessed with the Spearman rank correlation. Univariate Kaplan-Meier and multivariate Cox proportional hazards regression analyses were performed in the training cohort to identify independent predictors of OS and TTP. Their predictive capacity was tested on the validation cohort by using Kaplan-Meier analysis. Results Visual analysis of tumor heterogeneity correlated with entropy at both arterial (P = .012) and portal venous (P = .038) phases. Portal phase-derived entropy at fine (hazard ratio [HR], 5.08; P = .0033), medium (HR, 2.23; P = .019), and coarse (HR, 2.26; P = .0032) texture scales was identified as an independent predictor of OS and confirmed in the validation cohort (P < .05). The difference in median survival between patients in the validation cohort with entropy values below and above the identified threshold was 272 days (with fine texture) and 741 days (with medium and coarse textures). Arterial phase-derived texture parameters (P > .085) and visual analysis (P > .11) were not associated with changes in survival. Conclusion Pretreatment portal venous phase-derived tumor entropy may be a predictor of survival in patients with advanced HCC treated with sorafenib. PMID- 29584598 TI - Use of 2D U-Net Convolutional Neural Networks for Automated Cartilage and Meniscus Segmentation of Knee MR Imaging Data to Determine Relaxometry and Morphometry. AB - Purpose To analyze how automatic segmentation translates in accuracy and precision to morphology and relaxometry compared with manual segmentation and increases the speed and accuracy of the work flow that uses quantitative magnetic resonance (MR) imaging to study knee degenerative diseases such as osteoarthritis (OA). Materials and Methods This retrospective study involved the analysis of 638 MR imaging volumes from two data cohorts acquired at 3.0 T: (a) spoiled gradient recalled acquisition in the steady state T1rho-weighted images and (b) three dimensional (3D) double-echo steady-state (DESS) images. A deep learning model based on the U-Net convolutional network architecture was developed to perform automatic segmentation. Cartilage and meniscus compartments were manually segmented by skilled technicians and radiologists for comparison. Performance of the automatic segmentation was evaluated on Dice coefficient overlap with the manual segmentation, as well as by the automatic segmentations' ability to quantify, in a longitudinally repeatable way, relaxometry and morphology. Results The models produced strong Dice coefficients, particularly for 3D-DESS images, ranging between 0.770 and 0.878 in the cartilage compartments to 0.809 and 0.753 for the lateral meniscus and medial meniscus, respectively. The models averaged 5 seconds to generate the automatic segmentations. Average correlations between manual and automatic quantification of T1rho and T2 values were 0.8233 and 0.8603, respectively, and 0.9349 and 0.9384 for volume and thickness, respectively. Longitudinal precision of the automatic method was comparable with that of the manual one. Conclusion U-Net demonstrates efficacy and precision in quickly generating accurate segmentations that can be used to extract relaxation times and morphologic characterization and values that can be used in the monitoring and diagnosis of OA.

AB - Purpose To investigate the topologic architecture of white matter connectivity networks in preschool-aged children with a diagnosis of autism spectrum disorder (ASD) versus typical development (TD). Materials and Methods Forty-two participants were enrolled, including 21 preschool children with ASD (14 male children and seven female children; mean age, 4.56 years +/- 0.97 [standard deviation]) and 21 children with TD (11 males and 10 females; mean age, 5.13 years +/- 0.82). The diagnosis of ASD was determined according to the Diagnostic and Statistical Manual of Mental Disorders Global Assessment of Functioning scores (mean score, 8.00 +/- 0.50). All participants underwent diffusion-tensor imaging (DTI) and T2-weighted imaging on a 3-T magnetic resonance system. A graph theoretical analysis was applied to investigate the topologic organization of the brain network including global and local topologic parameters. Statistical analysis was then performed for the comparison between the groups. Results Compared with the TD group, children with ASD demonstrated shortened characteristic path length (t1 = 0.536, t2 = 0.534, t3 = 0.523, t4 = 0.510, and t5 = 0.501; P < .05) and increased global efficiency (t1 = 0.499, t2 = 0.497, t3 = 0.486, t4 = 0.473, and t5 = 0.465; P < .05) and clustering coefficient (t1 = 0.673, t2 = 0.750, t3 = 0.757, t4 = 0.738, and t5 = 0.741; P < .05). Significant increases in nodal efficiency were mainly found in left pallidum (0.037 vs 0.032, respectively; P < .01) and right caudate nucleus (0.037 vs 0.032, respectively; P < .01) of the basal ganglia network. Conclusion Significantly altered patterns of global and local brain network topography may underlie the abnormal brain development in preschool children with ASD compared with those who have TD. The identification of altered structural connectivity in basal ganglia and paralimbic limbic networks may point toward potential imaging biomarkers for preschool-age patients with ASD.

AB - : There is evidence in the literature that viable cryopreserved human placental membrane (vCHPM) grafts are effective in treating diabetic foot ulcers and venous leg ulcers. OBJECTIVE: This case series presents 3 cases of chronic ulcerations - 1 arterial ulcer (AU), 1 pressure ulcer (PU), and 1 recurrence of a pyoderma gangrenosum ulcer (PGU) - that had failed previous courses of standard wound care and were subsequently treated with vCHPM to determine if the treatment is an effective modality for treating wounds of these etiologies. MATERIALS AND METHODS: This retrospective review describes 3 cases in which patients with chronic wounds that had failed standard of care treatments for more than 4 weeks were subsequently treated with weekly applications of vCHPM. Each wound area was recorded and photographed on a weekly basis and wound area reduction also was charted weekly. RESULTS: The PU and AU both reached full closure in 4 and 5 weeks, respectively, without complication. The patient with the PGU achieved 64% closure after 9 applications of vCHPM. CONCLUSIONS: Viable CHPM is an effective treatment modality for wounds of diverse etiologies and shows better results than have been previously published with standard of care. In patients with PGUs, medical optimization and close management of comorbidities is essential in achieving optimal results. PMID- 29584602 TI - Effect of a New Purified Collagen Matrix With Polyhexamethylene Biguanide on Recalcitrant Wounds of Various Etiologies: A Case Series. AB - INTRODUCTION: The management of chronic, nonhealing wounds in patients with multiple comorbidities continues to be a challenge for health care practitioners. Chronic wounds typically do not progress through the normal phases of wound healing and generally remain stagnant during the inflammatory phase, resulting in an increase in proteolytic enzymes with degradation of the extracellular matrix. Bacterial biofilm has been documented to be one of the main factors delaying wound healing, resulting in the prolongation of the inflammatory phase. OBJECTIVE: In order to control biofilm formation, sequester proteolytic enzymes, and provide a biocompatible scaffold to support healing, the investigators utilize a purified collagen matrix containing polyhexamethylene biguanide (PCMP) in a case series of 9 wounds on 8 patients with multiple comorbidities who did not respond to previous conventional or adjuvant therapy. MATERIALS AND METHODS: Wound etiologies included 3 pressure ulcers, 1 diabetic foot ulcer, 1 venous leg ulcer, 2 postsurgical wound dehiscences, 1 ulcer secondary to calciphylaxis, and 1 traumatic wound secondary to hematoma. The average wound size at the first PCMP application was 34.0 cm2, and the wounds were present for an average of 9.2 weeks prior to the first PCMP application. RESULTS: Patients received an average of 5.8 PCMP applications. Of the 6 wounds that healed, average time to closure from the first PCMP application was 10 weeks. The remaining 3 wounds demonstrated improved wound appearance with 100% granulation tissue and an average area reduction during PCMP treatment of 61.4%. CONCLUSIONS: This case series demonstrated that PCMP along with good wound care supported both wound closure and improvements in wound bed condition and area reduction on recalcitrant, nonhealing wounds of various etiologies.

This brief report focuses on the potentially negative outcomes that may ensue as a result of MACs limiting the place of service for ulcer debridement. With the information included herein, the hope is that this problem can be addressed by all parties involved in wound care, including medical directors at these MACs, to remove this limitation impacting patient care. PMID- 29584605 TI - Evaluating the Impact of a Patient-centered Remote Monitoring Program on Adherence to Negative Pressure Wound Therapy. AB - : A remote therapy monitoring (RTM) system has been developed for use with a negative pressure wound therapy (NPWT) unit for patients in the home care setting. In conjunction with RTM, a network of trained professionals call patients when their NPWT usage is low and provide education to assist with therapy adherence. OBJECTIVE: The objective of this evaluation is to examine the relationship between the RTM system and patient adherence. MATERIALS AND METHODS: One hundred ninety-eight home care patients receiving NPWT with RTM between December 2016 and April 2017 were included. RESULTS: A total of 979 calls were made, with an average of 4.9 calls per patient. Among 198 patients, 195 received a welcome call, 157 received a call due to low adherence, and 35 had an escalation call made to their treating nurse. Of the 157 patients who required at least 1 call due to low adherence, 153 were successfully contacted at least once. The day following the patient call, adherence increased 73% of the time by an average of 8.5 hours. CONCLUSIONS: This evaluation suggests there is an ability to influence patient adherence through active engagement, potentially improving outcomes and reducing wound costs. PMID- 29584606 TI - Hereditary Sensory and Autonomic Neuropathy Presenting With Mutilating Trophic Ulcers. AB - Two siblings, a 19-year-old woman and an 18-year-old man, born to apparently normal parents of second-degree consanguineous marriage, presented to the Department of Dermatology, Sawai Man Singh Medical College Hospital, Jaipur, India, with recurrent skin ulcers of the hands and feet since early childhood. The ulcers were spontaneous, slow to heal, and caused deformities. On initial examination, they were found to have distal sensory loss, predominantly to pain and temperature. The patients were diagnosed with hereditary sensory and autonomic neuropathy of ulceromutilating type (Type 2) based on clinical evidences, nerve studies, and neuropathology. Although clinical features were distinct, due to slow progression of the disease and lack of clinical suspicion, diagnosis was delayed until adulthood when complications developed leading to deformities. Through this report, the authors intend to familiarize readers with this rare disease that can present with trophic ulcers.

AB - Calcinosis cutis (CC), or calcium deposition in soft tissue, can cause significant morbidity associated with arthralgias and ulceration. This condition has an elusive pathophysiology and is often associated with autoimmune disorders, significantly impacting the disease burden. The clinical presentation of CC varies, and there is no gold standard treatment modality. The case of a 50-year old woman with scleroderma and a rare presentation of milky drainage of a left hip ulcer secondary to underlying CC that was treated successfully with surgery and negative pressure wound therapy is reported herein. Also included is a review of the literature of the medical and surgical modalities used in the management of this debilitating condition. PMID- 29584608 TI - Utilization of a Viable Human Amnion Membrane Allograft in Elderly Patients With Chronic Lower Extremity Wounds of Various Etiologies. AB - : ntroduction. Chronic nonhealing wounds are a growing health care problem in the United States, afflicting more than 6.5 million patients annually. In particular, diseases that compromise skin integrity and impair normal wound healing processes, such as diabetes and peripheral vascular diseases, are becoming more common in the aging population and leading to ever-increasing incidence of these chronic nonhealing wounds. OBJECTIVE: The aim of this study is to evaluate a viable human amnion membrane allograft (vHAMA) for the treatment of chronic nonhealing wounds in elderly patients (aged > 65 years) with multiple comorbidities. MATERIALS AND METHODS: Four patients (age range, 69-85 years) with 5 chronic wounds of varying etiologies and sizes (2 traumatic wounds, 2 diabetic foot ulcers, and 1 venous leg ulcer) that persisted for at least 4 weeks and failed previous treatment with standard of care were included in this study. Comorbidities included diabetes mellitus, obesity, polymyalgia rheumatica, lymphedema, peripheral vascular disease, steroid use, and neuropathy. All patients received vHAMA once weekly or as deemed appropriate. RESULTS: All patients reached complete wound closure with no complications or adverse events. Mean time to closure was 4.8 weeks (range, 2-8 weeks) with an average of 4.2 grafts (range, 1-8). There was no wound recurrence. CONCLUSIONS: Successful closure of wounds indicates the use of vHAMA may be beneficial for treatment of chronic wounds in elderly patients with comorbidities. PMID- 29584609 TI - A Scoping Review of the Use of Silver-impregnated Dressings for the Treatment of Chronic Wounds. AB - Topical silver agents and dressings are used to control infection and promote healing in chronic wounds, but reviews published from 2006 to 2011 found heterogeneous results regarding their effectiveness. A scoping review was conducted to examine the extent, range, and nature of research activity surrounding chronic wound care that employed silver-impregnated dressings; identify research gaps in the existing literature; and summarize the evidence to provide recommendations for future clinical studies. Ten (10) electronic databases and additional sources were screened from their inception to May 2016; search terms for the different databases included but were not limited to silver, chronic, complications, wound, ulcer, and sore. English-language articles that compared silver dressings with an alternate treatment in adults with chronic wounds and that reported clinical outcome measures were included. Of 222 full text reviewed studies, 27 were included for qualitative analysis. Qualitative analysis was guided by key findings identified among the included studies that were analyzed in aggregate form where appropriate. In comparative analyses of the 26 studies that investigated wound healing, 15 revealed significantly positive wound healing outcomes with silver treatments versus 9 that did not; the remaining 2 failed to provide statistical values of significance. Of 17 studies that presented data on microbiology, 3 reported significant microbial load improvement for silver dressings, 9 noted nonsignificant findings, and 4 provided no statistical values. Pain, adverse events, and treatment cost were included in 5, 7, and 3 studies, respectively, with heterogeneous findings. The heterogeneous evidence regarding the impact of silver dressings on clinical outcomes may be related to differences in the silver treatments themselves, heterogeneous intervention strategies, study designs, outcomes, and measures. Well-designed clinical studies with multiple outcome parameters are necessary to determine the optimal type and use of silver-dressings in chronic wounds. PMID- 29584610 TI - A Quasi-experimental Study to Explore the Effect of Barrier Cream on the Peristomal Skin of Patients With a Tracheostomy. AB - Peristomal skin problems represent one of the most common complications of a tracheostomy. A quasi-experimental study was conducted among patients ages 18 to 65 years hospitalized in a Turkish university hospital ear-nose-throat clinic between August 15, 2013, and December 15, 2013, to compare the effect of using or not using a barrier cream on the peristomal skin with regard to pH, moisture, temperature, color, odor, turgor, infections, and lesions after tracheostomy surgery. Patients were selected using a purposeful sampling method and included if they had not undergone another operation for a complication (eg, pneumothorax, tube misplacement, hemorrhage) within 24 hours following the tracheostomy operation. In phase 1 of the study, 9 registered nurses were observed 3 times each by the researcher, who completed an observation form. From these observations and related nursing textbooks, the researcher developed a protocol entitled "Nursing Care Steps for Patients with a Tracheostomy." This protocol was followed during phase 2 of the study during which participants were alternately assigned to either the intervention (a barrier cream containing dimethicone, acrylate terpolymer, oils, paraffin, water, dicapryladipate, isopropyl palmitate, and PPG-15 stearyl ether followed by gauze) or control (gauze only) group (n = 30 each) and observed for 7 days. Demographic characteristics were gathered for each patient upon admission to the study. Peristomal skin was assessed in terms of pH, temperature, and moisture (relative humidity [RH]) using a surface pH meter, surface thermometer, and digital skin moisture tester, as well as for lesions, infection, and maceration. Findings were documented on a skin condition assessment form. Twenty-four (24) hours post surgery, the barrier cream plus gauze was applied over peristomal area in the study group and gauze dressing only in the control group. Peristomal skin pH, moisture, and temperature were within the normal range for both groups during all observations throughout the study but closer to normal ranges in the intervention group. Mean peristomal skin pH in the intervention group was significantly higher (5.452 +/- 0.043) than in the control group (5.123 +/- 0.057; P &.001), mean peristomal skin moisture in the control group (46.90 +/- 0.132 RH) was significantly greater than in the intervention group (41.71 +/- 0.774 RH; P &.001), and mean peristomal skin temperature in the control group (33.59 +/- 1.3 C) was significantly higher than in the intervention group (31.64 +/- 0.607 C; P &.001). In both groups, Staphylococcus epidermidis was the most commonly cultured microorganism, and S aureus was the most cultured pathological microorganism in addition to the normal skin flora. Peristomal skin condition was maintained for both the intervention and control groups. Use of a barrier cream to protect tracheostomy peristomal skin beneath absorbent dressings (eg, gauze) is recommended, but additional short-term and long-term studies are needed. PMID- 29584611 TI - A Descriptive, Retrospective Study of Using an Oblique Downward-design Gluteus Maximus Myocutaneous Flap for Reconstruction of Ischial Pressure Ulcers. AB - Despite advances in reconstruction techniques, ischial pressure ulcers continue to present a challenge for the plastic surgeon. The purpose of this retrospective study was to evaluate outcomes of using an oblique downward gluteus maximus myocutaneous (GMM) flap for coverage of grade IV ischial ulcers. Data regarding defect size, flap size, operation time, duration of wound healing, and surgical outcome were abstracted from the medical records of patients whose ischial pressure ulcers had been reconstructed using GMM island flaps between January 2010 and December 2015. The 22 patients comprised 15 men and 7 women with a mean age of 52 (range 16-81) years. Twenty (20) had paraplegia, 6 had a recurrent ischial ulcer, 2 were bedridden following a cerebrovascular accident, 1 had a myelomeningocele status post operation, and 19 were spinal cord injury patients. Follow-up time ranged from 6 to 40 months. Pressure ulcer size ranged from 3 cm x 2 cm to 10 cm x 5 cm (average 22.3 cm2). The average flap size was 158 cm2 (15.9 cm x 9.7 cm); the largest was 286 cm2 (22 cm x 13 cm). The operating time ranged from 52 minutes to 110 minutes (average, 80 minutes). In 2 cases, wound dehiscence occurred but completely healed after resuturing. One (1) ischial pressure ulcer recurred 6 months following surgery and was successfully covered with a pedicled anterolateral thigh flap. No recurrences or problems were observed in the remaining 20 patients. Time to complete wound healing ranged from 14 to 24 days (average 17.8 days). Treatment of ischial pressure ulcers with GMM flaps allowed for an easy, simple procedure that provided the adequate thickness of soft tissue needed to cover the bony prominence, fill dead space, and cover the lesion. This technique was a reliable and safe reconstructive modality for the management of ischial pressure ulcers, even in recurrent cases.

PMID- 29584615 TI - Metabolic and genetic markers' associations with elevated levels of alanine aminotransferase in adolescents. AB - BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disease in adolescents, is a feature of metabolic syndrome (MetS). Obesity and insulin resistance (IR) are risk factors for NAFLD, as well as inflammation related genetic markers. The relationship between metabolic or inflammation related genetic markers and alanine aminotransferase (ALT) is not fully understood. We examined the relationship of MetS, metabolic and inflammation related genetic markers with elevated ALT in adolescents. METHODS: A total of 674 adolescents participated in a cross-sectional study in Guadalajara, Mexico. Elevated ALT (>40 IU/L), a surrogate marker of NAFLD, and MetS (International Diabetes Federation definition) were evaluated. Obesity, IR, lipids, C-reactive protein (CRP) and genetic markers (TNFA-308G>A, CRP+1444C>T, IL1RN and IL6-597/ 572/-174 haplotype) were evaluated. Multivariate logistic regression was performed. RESULTS: Elevated ALT was observed in 3% and 14.1% (total and obese, respectively) of the adolescents. Obesity (odds ratio [OR], 5.86; 95% confidence interval [95% CI], 1.16-25.89), insulin (OR, 8.51; 95% CI, 2.61-27.71), IR (OR, 9.10; 95% CI, 2.82-29.38), total cholesterol (TC) (OR, 3.67; 95% CI, 1.25-10.72), low-density lipoprotein-cholesterol (LDL-C) (OR, 3.06; 95% CI, 1.06-8.33), non high-density lipoprotein-cholesterol (HDL-C) (OR, 3.88; 95% CI, 1.27-11.90) and IL1RN (OR, 4.64; 95% CI, 1.10-19.53) were associated with elevated ALT. Among males, >=2 MetS criteria were associated with elevated ALT (OR, 4.22; 95% CI, 1.14-15.71). CONCLUSIONS: Obesity, insulin, IR, high TC, high LDL-C, high non-HDL C and IL1RN polymorphism were associated with elevated ALT. Among males, >=2 MetS criteria were associated with elevated ALT. There is an urgent need to reduce obesity and IR in adolescents to prevent NAFLD. PMID- 29584616 TI - Phenotypic presentation of adolescents with overt primary hypothyroidism. AB - BACKGROUND: The phenotypic presentation of overt hypothyroidism during adolescence is less well characterized. The aim of the study was to study the phenotypic presentation of patients with overt hypothyroidism presenting during adolescence (age 9-18 years). METHODS: Records of adolescent patients with overt hypothyroidism (thyroid stimulating hormone [TSH]>10 mIU/L) were retrospectively analyzed for presenting complaints, height and pubertal status. RESULTS: A total of 67 patients (40 females and 37 males, average age 13.2+2.3 years) with a mean TSH of 241.3+/-336.6 mIU/L were included. The commonest presentation was short stature in 46.2% of patients followed by neck swelling (16.4%) and weight gain (11.9%). The mean height standard deviation score (SDS) was -2.5+2.11, 43% of patients had less than 3 SDS. The height age and bone age were around 3 years less than the chronological age. The bone age significantly correlated with the height age but not with TSH levels. Three patients referred from neurology with primary complaints of headache had pituitary hyperplasia and one presented with hypokalemic periodic paralysis. Seven had delayed puberty and one patient had early periods due to huge ovarian cysts. CONCLUSIONS: In the present study, severe short stature and uncommon phenotypic presentations were a consequence of long-standing severe untreated hypothyroidism. PMID- 29584617 TI - Constitutively active follicle-stimulating hormone receptor enables androgen independent spermatogenesis. AB - Spermatogenesis is regulated by the 2 pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This process is considered impossible without the absolute requirement of LH-stimulated testicular testosterone (T) production. The role of FSH remains unclear because men and mice with inactivating FSH receptor (FSHR) mutations are fertile. We revisited the role of FSH in spermatogenesis using transgenic mice expressing a constitutively strongly active FSHR mutant in a LH receptor-null (LHR-null) background. The mutant FSHR reversed the azoospermia and partially restored fertility of Lhr-/- mice. The finding was initially ascribed to the residual Leydig cell T production. However, when T action was completely blocked with the potent antiandrogen flutamide, spermatogenesis persisted. Hence, completely T independent spermatogenesis is possible through strong FSHR activation, and the dogma of T being a sine qua non for spermatogenesis may need modification. The mechanism for the finding appeared to be that FSHR activation maintained the expression of Sertoli cell genes considered androgen dependent. The translational message of our findings is the possibility of developing a new strategy of high dose FSH treatment for spermatogenic failure. Our findings also provide an explanation of molecular pathogenesis for Pasqualini syndrome (fertile eunuchs; LH/T deficiency with persistent spermatogenesis) and explain how the hormonal regulation of spermatogenesis has shifted from FSH to T dominance during evolution. PMID- 29584618 TI - Role of proNGF/p75 signaling in bladder dysfunction after spinal cord injury. AB - Loss of bladder control is a challenging outcome facing patients with spinal cord injury (SCI). We report that systemic blocking of pro-nerve growth factor (proNGF) signaling through p75 with a CNS-penetrating small-molecule p75 inhibitor resulted in significant improvement in bladder function after SCI in rodents. The usual hyperreflexia was attenuated with normal bladder pressure, and automatic micturition was acquired weeks earlier than in the controls. The improvement was associated with increased excitatory input to the spinal cord, in particular onto the tyrosine hydroxylase-positive fibers in the dorsal commissure. The drug also had an effect on the bladder itself, as the urothelial hyperplasia and detrusor hypertrophy that accompany SCI were largely prevented. Urothelial cell loss that precedes hyperplasia was dependent on p75 in response to urinary proNGF that is detected after SCI in rodents and humans. Surprisingly, death of urothelial cells and the ensuing hyperplastic response were beneficial to functional recovery. Deleting p75 from the urothelium prevented urothelial death, but resulted in reduction in overall voiding efficiency after SCI. These results unveil a dual role of proNGF/p75 signaling in bladder function under pathological conditions with a CNS effect overriding the peripheral one. PMID- 29584619 TI - PAI1 mediates fibroblast-mast cell interactions in skin fibrosis. AB - Fibrosis is a prevalent pathological condition arising from the chronic activation of fibroblasts. This activation results from the extensive intercellular crosstalk mediated by both soluble factors and direct cell-cell connections. Prominent among these are the interactions of fibroblasts with immune cells, in which the fibroblast-mast cell connection, although acknowledged, is relatively unexplored. We have used a Tg mouse model of skin fibrosis, based on expression of the transcription factor Snail in the epidermis, to probe the mechanisms regulating mast cell activity and the contribution of these cells to this pathology. We have discovered that Snail-expressing keratinocytes secrete plasminogen activator inhibitor type 1 (PAI1), which functions as a chemotactic factor to increase mast cell infiltration into the skin. Moreover, we have determined that PAI1 upregulates intercellular adhesion molecule type 1 (ICAM1) expression on dermal fibroblasts, rendering them competent to bind to mast cells. This heterotypic cell-cell adhesion, also observed in the skin fibrotic disorder scleroderma, culminates in the reciprocal activation of both mast cells and fibroblasts, leading to the cascade of events that promote fibrogenesis. Thus, we have identified roles for PAI1 in the multifactorial program of fibrogenesis that expand its functional repertoire beyond its canonical role in plasmin-dependent processes. PMID- 29584622 TI - Factors affecting longitudinal changes in cardio-ankle vascular index in a large general population: the Nagahama study. AB - BACKGROUND: Cardio-ankle vascular index (CAVI) has been increasingly used as an index for arterial stiffness. However, the degree of longitudinal changes and factors affecting these changes in CAVI (DeltaCAVI) are largely unknown. The aim of this study was to descriptively clarify factors associated with longitudinal DeltaCAVI for the precise use of this index in the assessment of arterial stiffness. METHODS: Study participants comprised 9501 community residents (53.1 +/- 13.3 years), with 8004 patients included in the longitudinal analysis. CAVI was calculated by the transient time interval of arterial waveform measured at four extremities. RESULTS: Factors showing a strong association with baseline CAVI (7.38 +/- 1.10) included age (beta = 0.586), SBP (beta = 0.175), and male sex (beta = 0.142), whereas BMI showed an inverse association (beta = -0.208) (all P < 0.001). During the 1815 +/- 135 days follow-up period, CAVI increased by 0.47 +/- 0.68. Multivariate analysis identified age (beta = 0.508), male sex (beta = 0.089), Brinkman index (beta = 0.074), and SBP (beta = 0.037) as positive determinants, whereas BMI (beta = -0.079) and baseline CAVI (beta = -0.590) as inverse determinants for DeltaCAVI (all P < 0.001). Further data accumulation is needed to determine a reference value of CAVI due to its large population differences. CONCLUSION: Several factors were commonly associated with baseline and longitudinal DeltaCAVI. These factors should be carefully considered when CAVI is used for the assessment of arterial stiffness. PMID- 29584621 TI - Blocking fatty acid-fueled mROS production within macrophages alleviates acute gouty inflammation. AB - Gout is the most common inflammatory arthritis affecting men. Acute gouty inflammation is triggered by monosodium urate (MSU) crystal deposition in and around joints that activates macrophages into a proinflammatory state, resulting in neutrophil recruitment. A complete understanding of how MSU crystals activate macrophages in vivo has been difficult because of limitations of live imaging this process in traditional animal models. By live imaging the macrophage and neutrophil response to MSU crystals within an intact host (larval zebrafish), we reveal that macrophage activation requires mitochondrial ROS (mROS) generated through fatty acid oxidation. This mitochondrial source of ROS contributes to NF kappaB-driven production of IL-1beta and TNF-alpha, which promote neutrophil recruitment. We demonstrate the therapeutic utility of this discovery by showing that this mechanism is conserved in human macrophages and, via pharmacologic blockade, that it contributes to neutrophil recruitment in a mouse model of acute gouty inflammation. To our knowledge, this study is the first to uncover an immunometabolic mechanism of macrophage activation that operates during acute gouty inflammation. Targeting this pathway holds promise in the management of gout and, potentially, other macrophage-driven diseases. PMID- 29584620 TI - JAM3 maintains leukemia-initiating cell self-renewal through LRP5/AKT/beta catenin/CCND1 signaling. AB - Leukemia-initiating cells (LICs) are responsible for the initiation, development, and relapse of leukemia. The identification of novel therapeutic LIC targets is critical to curing leukemia. In this report, we reveal that junctional adhesion molecule 3 (JAM3) is highly enriched in both mouse and human LICs. Leukemogenesis is almost completely abrogated upon Jam3 deletion during serial transplantations in an MLL-AF9-induced murine acute myeloid leukemia model. In contrast, Jam3 deletion does not affect the functions of mouse hematopoietic stem cells. Moreover, knockdown of JAM3 leads to a dramatic decrease in the proliferation of both human leukemia cell lines and primary LICs. JAM3 directly associates with LRP5 to activate the downstream PDK1/AKT pathway, followed by the downregulation of GSK3beta and activation of beta-catenin/CCND1 signaling, to maintain the self renewal ability and cell cycle entry of LICs. Thus, JAM3 may serve as a functional LIC marker and play an important role in the maintenance of LIC stemness through unexpected LRP5/PDK1/AKT/GSK3beta/beta-catenin/CCND1 signaling pathways but not via its canonical role in cell junctions and migration. JAM3 may be an ideal therapeutic target for the eradication of LICs without influencing normal hematopoiesis. PMID- 29584623 TI - Baduanjin Exercise for Stroke Rehabilitation: A Systematic Review with Meta Analysis of Randomized Controlled Trials. AB - Objective: The purpose of this review was to objectively evaluate the effects of Baduanjin exercise on rehabilitative outcomes in stroke patients. Methods: Both Chinese and English electronic databases were searched for potentially relevant trials. Two review authors independently screened eligible trials against the inclusion criteria, extracted data, and assessed the methodological quality by using the revised PEDro scale. Meta-analysis was only performed for balance function. Results: In total, there were eight randomized controlled trials selected in this systematic review. The aggregated result of four trials has shown a significant benefit in favor of Baduanjin on balance function (Hedges' g = 2.39, 95% CI 2.14 to 2.65, p < 0.001, I2 = 61.54). Additionally, Baduanjin exercise effectively improved sensorimotor function of lower extremities and ability of daily activities as well as reduced depressive level, leading to improved quality of life. Conclusion: Baduanjin exercise as an adjunctive and safe method may be conducive to help stroke patients achieve the best possible short-term outcome and should be integrated with mainstream rehabilitation programs. More rigorous randomized controlled trials with long-term intervention periods among a large sample size of stroke patients are needed to draw a firm conclusion regarding the rehabilitative effects for this population. PMID- 29584624 TI - Sex-Specificity of Oxidative Stress in Newborns Leading to a Personalized Antioxidant Nutritive Strategy. AB - : Oxidative stress is a critical process that triggers several diseases observed in premature infants. Growing recognition of the detriment of oxidative stress in newborns warrants the use of an antioxidant strategy that is likely to be nutritional in order to restore redox homeostasis. It appears essential to have a personalized approach that will take into account the age of gestation at birth and the sex of the infant. However, the link between sex and oxidative stress remains unclear. The aim of this study was to find a common denominator explaining the discrepancy between studies related to sex-specific effects of oxidative stress. Results highlight a specificity of sex in the levels of oxidative stress markers linked to the metabolism of glutathione, as measured in the intracellular compartments. Levels of all sex-dependent oxidative stress markers are greater and markers associated to a better antioxidant defense are lower in boys compared to girls during the neonatal period. This sex-specific discrepancy is likely to be related to estrogen metabolism, which is more active in baby-girls and promotes the activation of glutathione metabolism. CONCLUSION: our observations suggest that nutritive antioxidant strategies need to target glutathione metabolism and, therefore, should be personalized considering, among others, the sex specificity. PMID- 29584625 TI - Association of Overcrowding and Turnover with Self-Harm in a Swiss Pre-Trial Prison. AB - Self-harm is a common issue in detention and includes both suicidal and non suicidal behaviours. Beyond well-known individual risk factors, institutional factors such as overcrowding (i.e., when the prison population exceeds its capacity) and turnover (i.e., the rate at which the prison population is renewed), may also increase the risk of self-harm. However, these factors are understudied or previous studies reported inconsistent findings. This study investigated the association of self-harm with overcrowding and turnover in the largest pre-trial Swiss prison in Geneva. Data were collected yearly between 2011 and 2017. Measures included self-harm (all kinds of self-injuring acts requiring medical attention, including self-strangulations and self-hangings). We performed meta-regressions to analyse the relationships between self-harm and institutional factors. Self-harm events were frequent, with a prevalence estimate of 26.4%. Overcrowding and turnover were high (average occupation rate of 177% and average turnover of 73%, respectively). Overcrowding and turnover were significantly associated with self-harm (respectively b = 0.068, p < 0.001 and (b = 1.257, p < 0.001). In both cases, self-harm was higher when overcrowding and turnover increased. Overcrowding and turnover raise important human rights concerns and have damaging effects on the health of people living in detention. Identification of and care for this vulnerable population at risk of self-harm are needed and institutional factors should be addressed. PMID- 29584626 TI - Characterization of Fine Particulate Matter and Associated Health Burden in Nanjing. AB - Particulate matter (PM) air pollution has become a serious environmental problem in Nanjing and poses great health risks to local residents. In this study, characteristics of particulate matter with an aerodynamic diameter less than 2.5 MUm (PM2.5) over Nanjing were analyzed using hourly and daily averaged PM2.5 concentrations and meteorological parameters collected from nine national monitoring sites during the period of March 2014 to February 2017. Then, the integrated exposure-response (IER) model was applied to assess premature mortality, years of life lost (YLL) attributable to PM2.5, and mortality benefits due to PM2.5 reductions. The concentrations of PM2.5 varied among hours, seasons and years, which can be explained by differences in emission sources, secondary formations and meteorological conditions. The decreased ratio of PM2.5 to CO suggested that secondary contributions decreased while the relative contributions of vehicle exhaust increased from increased CO data. According to the values of attributable fractions (AF), stroke was the major cause of death, followed by ischemic heart disease (IHD), lung cancer (LC) and chronic obstructive pulmonary disease (COPD). The estimated total deaths in Nanjing due to PM2.5 were 12,055 and 10,771, leading to 98,802 and 87,647 years of life lost in 2014 and 2015, respectively. The elderly and males had higher health risks than youngsters and females. When the PM2.5 concentrations meet the World Health Organization (WHO) Air Quality Guidelines (AQG) of 10 MUg/m3, 84% of the premature deaths would be avoided, indicating that the Nanjing government needs to adopt more stringent measure to reduce PM pollution and enhance the health benefits. PMID- 29584628 TI - Evaluation of Loss Due to Storm Surge Disasters in China Based on Econometric Model Groups. AB - Storm surge has become an important factor restricting the economic and social development of China's coastal regions. In order to improve the scientific judgment of future storm surge damage, a method of model groups is proposed to refine the evaluation of the loss due to storm surges. Due to the relative dispersion and poor regularity of the natural property data (login center air pressure, maximum wind speed, maximum storm water, super warning water level, etc.), storm surge disaster is divided based on eight kinds of storm surge disaster grade division methods combined with storm surge water, hypervigilance tide level, and disaster loss. The storm surge disaster loss measurement model groups consist of eight equations, and six major modules are constructed: storm surge disaster in agricultural loss, fishery loss, human resource loss, engineering facility loss, living facility loss, and direct economic loss. Finally, the support vector machine (SVM) model is used to evaluate the loss and the intra-sample prediction. It is indicated that the equations of the model groups can reflect in detail the relationship between the damage of storm surges and other related variables. Based on a comparison of the original value and the predicted value error, the model groups pass the test, providing scientific support and a decision basis for the early layout of disaster prevention and mitigation. PMID- 29584627 TI - Multi-Scale Clustering of Lyme Disease Risk at the Expanding Leading Edge of the Range of Ixodes scapularis in Canada. AB - Since its detection in Canada in the early 1990s, Ixodes scapularis, the primary tick vector of Lyme disease in eastern North America, has continued to expand northward. Estimates of the tick's broad-scale distribution are useful for tracking the extent of the Lyme disease risk zone; however, tick distribution may vary widely within this zone. Here, we investigated I. scapularis nymph distribution at three spatial scales across the Lyme disease emergence zone in southern Quebec, Canada. We collected ticks and compared the nymph densities among different woodlands and different plots and transects within the same woodland. Hot spot analysis highlighted significant nymph clustering at each spatial scale. In regression models, nymph abundance was associated with litter depth, humidity, and elevation, which contribute to a suitable habitat for ticks, but also with the distance from the trail and the type of trail, which could be linked to host distribution and human disturbance. Accounting for this heterogeneous nymph distribution at a fine spatial scale could help improve Lyme disease management strategies but also help people to understand the risk variation around them and to adopt appropriate behaviors, such as staying on the trail in infested parks to limit their exposure to the vector and associated pathogens. PMID- 29584629 TI - Co-Culture with Human Osteoblasts and Exposure to Extremely Low Frequency Pulsed Electromagnetic Fields Improve Osteogenic Differentiation of Human Adipose Derived Mesenchymal Stem Cells. AB - Human adipose-derived mesenchymal stem cells (Ad-MSCs) have been proposed as suitable option for cell-based therapies to support bone regeneration. In the bone environment, Ad-MSCs will receive stimuli from resident cells that may favor their osteogenic differentiation. There is recent evidence that this process can be further improved by extremely low frequency pulsed electromagnetic fields (ELF PEMFs). Thus, the project aimed at (i) investigating whether co-culture conditions of human osteoblasts (OBs) and Ad-MSCs have an impact on their proliferation and osteogenic differentiation; (ii) whether this effect can be further improved by repetitive exposure to two specific ELF-PEMFs (16 and 26 Hz); (iii) and the effect of these ELF-PEMFs on human osteoclasts (OCs). Osteogenic differentiation was improved by co-culturing OBs and Ad-MSCs when compared to the individual mono-cultures. An OB to Ad-MSC ratio of 3:1 had best effects on total protein content, alkaline phosphatase (AP) activity, and matrix mineralization. Osteogenic differentiation was further improved by both ELF-PEMFs investigated. Interestingly, only repetitive exposure to 26 Hz ELF-PEMF increased Trap5B activity in OCs. Considering this result, a treatment with gradually increasing frequency might be of interest, as the lower frequency (16 Hz) could enhance bone formation, while the higher frequency (26 Hz) could enhance bone remodeling. PMID- 29584630 TI - Gut Microbiota and Type 1 Diabetes. AB - Recently, the onset of type 1 diabetes (T1D) has increased rapidly and became a major public health concern worldwide. Various factors are associated with the development of T1D, such as diet, genome, and intestinal microbiota. The gastrointestinal (GI) tract harbors a complex and dynamic population of microorganisms, the gut microbiota, which exert a marked influence on the host homeostasis and metabolic diseases. Recent evidence shows that altered gut bacterial composition (dysbiosis) is highly associated with the pathogenesis of insulin dysfunction and T1D and, thus, targeting gut microbiota may serve as a therapeutic potential for T1D patients. In this study, we updated the effect of gut microbiota on T1D and potential mechanisms were discussed. PMID- 29584631 TI - Future Orientation among Students Exposed to School Bullying and Cyberbullying Victimization. AB - Future orientation can be defined as an individual's thoughts, beliefs, plans, and hopes for the future. Earlier research has shown adolescents' future orientation to predict outcomes later in life, which makes it relevant to analyze differences in future orientation among youth. The aim of the present study was to analyze if bullying victimization was associated with an increased likelihood of reporting a pessimistic future orientation among school youth. To be able to distinguish between victims and bully-victims (i.e., students who are both bullies and victims), we also took perpetration into account. The data were derived from the Stockholm School Survey performed in 2016 among ninth grade students (ages 15-16 years) (n = 5144). Future orientation and involvement in school bullying and in cyberbullying were based on self-reports. The statistical method used was binary logistic regression. The results demonstrated that victims and bully-victims of school bullying and of cyberbullying were more likely to report a pessimistic future orientation compared with students not involved in bullying. These associations were shown also when involvement in school bullying and cyberbullying were mutually adjusted. The findings underline the importance of anti-bullying measures that target both school bullying and cyberbullying. PMID- 29584632 TI - Inhibition of Zika Virus Replication by Silvestrol. AB - The Zika virus (ZIKV) outbreak in 2016 in South America with specific pathogenic outcomes highlighted the need for new antiviral substances with broad-spectrum activities to react quickly to unexpected outbreaks of emerging viral pathogens. Very recently, the natural compound silvestrol isolated from the plant Aglaia foveolata was found to have very potent antiviral effects against the (-)-strand RNA-virus Ebola virus as well as against Corona- and Picornaviruses with a (+) strand RNA-genome. This antiviral activity is based on the impaired translation of viral RNA by the inhibition of the DEAD-box RNA helicase eukaryotic initiation factor-4A (eIF4A) which is required to unwind structured 5'-untranslated regions (5'-UTRs) of several proto-oncogenes and thereby facilitate their translation. Zika virus is a flavivirus with a positive-stranded RNA-genome harboring a 5' capped UTR with distinct secondary structure elements. Therefore, we investigated the effects of silvestrol on ZIKV replication in A549 cells and primary human hepatocytes. Two different ZIKV strains were used. In both infected A549 cells and primary human hepatocytes, silvestrol has the potential to exert a significant inhibition of ZIKV replication for both analyzed strains, even though the ancestor strain from Uganda is less sensitive to silvestrol. Our data might contribute to identify host factors involved in the control of ZIKV infection and help to develop antiviral concepts that can be used to treat a variety of viral infections without the risk of resistances because a host protein is targeted. PMID- 29584633 TI - Temperature and Vibration Dependence of the Faraday Effect of Gd2O3 NPs-Doped Alumino-Silicate Glass Optical Fiber. AB - All-optical fiber magnetic field sensor based on the Gd2O3 nano-particles (NPs) doped alumino-silicate glass optical fiber was developed, and its temperature and vibration dependence on the Faraday Effect were investigated. Uniformly embedded Gd2O3 NPs were identified to form in the core of the fiber, and the measured absorption peaks of the fiber appearing at 377 nm, 443 nm, and 551 nm were attributed to the Gd2O3 NPs incorporated in the fiber core. The Faraday rotation angle (FRA) of the linearly polarized light was measured at 650 nm with the induced magnetic field by the solenoid. The Faraday rotation angle was found to increase linearly with the magnetic field, and it was about 18.16 degrees +/- 0.048 degrees at 0.142 Tesla (T) at temperatures of 25 degrees C-120 degrees C, by which the estimated Verdet constant was 3.19 rad/(T?m) +/- 0.01 rad/(T?m). The variation of the FRA with time at 0.142 T and 120 degrees C was negligibly small (-9.78 * 10-4 degrees /min). The variation of the FRA under the mechanical vibration with the acceleration below 10 g and the frequency above 50 Hz was within 0.5 degrees . PMID- 29584634 TI - Printing and Folding: A Solution for High-Throughput Processing of Organic Thin Film Thermoelectric Devices. AB - Wearable electronics are rapidly expanding, especially in applications like health monitoring through medical sensors and body area networks (BANs). Thermoelectric generators (TEGs) have been the main candidate among the different types of energy harvesting methods for body-mounted or even implantable sensors. Introducing new semiconductor materials like organic thermoelectric materials and advancing manufacturing techniques are paving the way to overcome the barriers associated with the bulky and inflexible nature of the common TEGs and are making it possible to fabricate flexible and biocompatible modules. Yet, the lower efficiency of these materials in comparison with bulk-inorganic counterparts as well as applying them mostly in the form of thin layers on flexible substrates limits their applications. This research aims to improve the functionality of thin and flexible organic thermoelectric generators (OTEs) by utilizing a novel design concept inspired by origami. The effects of critical geometric parameters are investigated using COMSOL Multiphysics to further prove the concept of printing and folding as an approach for the system level optimization of printed thin film TEGs. PMID- 29584635 TI - The Synthesis of Molecular Docking Studies, In Vitro Antimicrobial and Antifungal Activities of Novel Dipeptide Derivatives Based on N-(2-(2-Hydrazinyl-2 oxoethylamino)-2-oxoethyl)-nicotinamide. AB - A series of linear dipeptide derivatives (4-10) were prepared and evaluated as antimicrobial agents via the synthesis of N-(2-(2-hydrazinyl-2-oxoethylamino)-2 oxoethyl) nicotinamide (4). Compound 4 was reacted with 4-chlorobenzaldehyde or 4 hydroxybenzaldehyde, to give the hydrazones 5 and 6, respectively. On the other hand, Compound 4 was coupled with phenylisocyanate or methylisothiocyanate to give Compounds 7 and 8, respectively. The latter compounds (7 and 8) were coupled with chloroacetic acid to give oxazolidine (9) and thiazolidine (10), respectively. The newly synthesized dipeptide compounds were confirmed by means of their spectral data. The antimicrobial activity of the newly synthesized compounds 4-10 was evaluated by agar well diffusion, and they showed good activity. Compounds 4, 5, and 9 gave the most promising activity in this study. Most of the tested compounds possessed MIC values ranging from 50 to 500 ug/mL. Furthermore, docking studies were carried out on enoyl reductase from E. coli and cytochrome P450 14 alpha-sterol demethylase (Cyp51) from Candida albicans active sites. The MolDock scores of the seven tested compounds ranged between -117 and 171 and between -107 and -179, respectively. PMID- 29584636 TI - Response of Plant Secondary Metabolites to Environmental Factors. AB - Plant secondary metabolites (SMs) are not only a useful array of natural products but also an important part of plant defense system against pathogenic attacks and environmental stresses. With remarkable biological activities, plant SMs are increasingly used as medicine ingredients and food additives for therapeutic, aromatic and culinary purposes. Various genetic, ontogenic, morphogenetic and environmental factors can influence the biosynthesis and accumulation of SMs. According to the literature reports, for example, SMs accumulation is strongly dependent on a variety of environmental factors such as light, temperature, soil water, soil fertility and salinity, and for most plants, a change in an individual factor may alter the content of SMs even if other factors remain constant. Here, we review with emphasis how each of single factors to affect the accumulation of plant secondary metabolites, and conduct a comparative analysis of relevant natural products in the stressed and unstressed plants. Expectantly, this documentary review will outline a general picture of environmental factors responsible for fluctuation in plant SMs, provide a practical way to obtain consistent quality and high quantity of bioactive compounds in vegetation, and present some suggestions for future research and development. PMID- 29584637 TI - Mutations in the Non-Structural Protein-Coding Sequence of Protoparvovirus H-1PV Enhance the Fitness of the Virus and Show Key Benefits Regarding the Transduction Efficiency of Derived Vectors. AB - Single nucleotide changes were introduced into the non-structural (NS) coding sequence of the H-1 parvovirus (PV) infectious molecular clone and the corresponding virus stocks produced, thereby generating H1-PM-I, H1-PM-II, H1-PM III, and H1-DM. The effects of the mutations on viral fitness were analyzed. Because of the overlapping sequences of NS1 and NS2, the mutations affected either NS2 (H1-PM-II, -III) or both NS1 and NS2 proteins (H1-PM-I, H1-DM). Our results show key benefits of PM-I, PM-II, and DM mutations with regard to the fitness of the virus stocks produced. Indeed, these mutants displayed a higher production of infectious virus in different cell cultures and better spreading capacity than the wild-type virus. This correlated with a decreased particle-to infectivity (P/I) ratio and stimulation of an early step(s) of the viral cycle prior to viral DNA replication, namely, cell binding and internalization. These mutations also enhance the transduction efficiency of H-1PV-based vectors. In contrast, the PM-III mutation, which affects NS2 at a position downstream of the sequence deleted in Del H-1PV, impaired virus replication and spreading. We hypothesize that the NS2 protein-modified in H1-PM-I, H1-PM-II, and H1-DM-may result in the stimulation of some maturation step(s) of the capsid and facilitate virus entry into subsequently infected cells.

AB - In this paper, the electronic transduction of DNA hybridization is presented by coupling organic charge-modulated field-effect transistors (OCMFETs) and hairpin shaped probes. These probes have shown interesting properties in terms of sensitivity and selectivity in other kinds of assays, in the form of molecular beacons (MBs). Their integration with organic-transistor based sensors, never explored before, paves the way to a new class of low-cost, easy-to-use, and portable genetic sensors with enhanced performances. Thanks to the peculiar characteristics of the employed sensor, measurements can be performed at relatively high ionic strengths, thus optimizing the probes' functionality without affecting the detection ability of the device. A complete electrical characterization of the sensor is reported, including calibration with different target concentrations in the measurement environment and selectivity evaluation. In particular, DNA hybridization detection for target concentration as low as 100 pM is demonstrated.

A Suitable Alternative towards Novel Aza-Analogues of Falipamil. AB - We describe the one-pot synthesis of twenty polyheterocyclic pyrrolo[3,4 b]pyridin-5-ones via a cascade process (Ugi-3CR/aza Diels-Alder/N acylation/aromatization) in 20 to 95% overall yields, as well as four pharmacologically promising analogues via an improved cascade process (Ugi 3CR/aza Diels-Alder/N-acylation/aromatization/SN2): two piperazine-linked pyrrolo[3,4-b]pyridin-5-ones in 33 and 34%, and a couple of Falipamil aza analogues in 30 and 35% overall yields. It is worth highlighting the good substrate scope found, because final products are furnished with alkyl, aryl, and heterocyclic substituents. The use of chain-ring tautomerizable isocyanides (as key reagents for the Ugi-type three component reaction) allowed for a rapid and efficient assembly of the polysubstituted oxindoles, which were used in situ toward the complex products, conferring features like robustness, sustainability, and the one-pot approach to this synthetic methodology.

AB - The therapeutic benefits of GreenshellTM mussel (GSM; Perna canaliculus) preparations have been studied using in vitro test systems, animal models, and human clinical trials focusing mainly on anti-inflammatory and anti-arthritic effects. Activity is thought to be linked to key active ingredients that include omega-3 polyunsaturated fatty acids, a variety of carotenoids and other bioactive compounds. In this paper, we review the studies that have been undertaken in dogs, cats, and horses, and outline new research directions in shellfish breeding and high-value nutrition research programmes targeted at enhancing the efficacy of mussel and algal extracts. The addition of GSM to animal diets has alleviated feline degenerative joint disease and arthritis symptoms, and chronic orthopaedic pain in dogs. In horses, GSM extracts decreased the severity of lameness and joint pain and provided improved joint flexion in limbs with lameness attributed to osteoarthritis. Future research in this area should focus on elucidating the key active ingredients in order to link concentrations of these active ingredients with their pharmacokinetics and therapeutic effects. This would enable consistent and improved efficacy from GSM-based products for the purpose of improved animal health.

AB - Tri-ponderal mass index (TMI) and fat mass index (FMI) have been proposed as alternative approaches for assessing body fat since BMI does not ensure an accurate screening for obesity and overweight status in children and adolescents. This study proposes thresholds of the TMI and FMI for the prediction of metabolic syndrome (MetS) in children and young people. For this purpose, a cross-sectional study was conducted on 4673 participants (57.1% females), who were 9-25 years of age. As part of the study, measurements of the subjects' weight, waist circumference, serum lipid indices, blood pressure and fasting plasma glucose were taken. Body composition was measured by bioelectrical impedance analysis (BIA). The TMI and FMI were calculated as weight (kg)/height (m3) and fat mass (kg)/height (m3), respectively. Following the International Diabetes Federation (IDF) definition, MetS is defined as including three or more metabolic abnormalities. Cohort-specific thresholds were established to identify Colombian children and young people at high risk of MetS. The thresholds were applied to the following groups: (i) a cohort of children where the girls' TMI >= 12.13 kg/m3 and the boys' TMI >= 12.10 kg/m3; (ii) a cohort of adolescents where the girls' TMI >= 12.48 kg/m3 and the boys' TMI >= 11.19 kg/m3; (iii) a cohort of young adults where the women's TMI >= 13.21 kg/m3 and the men's TMI >= 12.19 kg/m3. The FMI reference cut-off values used for the different groups were as follows: (i) a cohort of children where the girls' FMI >= 2.59 fat mass/m3 and the boys' FMI >= 1.98 fat mass/m3; (ii) a cohort of adolescents where the girls' FMI >= 3.12 fat mass/m3 and the boys' FMI >= 1.46 fat mass/m3; (iii) a cohort of adults where the women's FMI >= 3.27 kg/m3 and the men's FMI >= 1.65 kg/m3. Our results showed that the FMI and TMI had a moderate discriminatory power to detect MetS in Colombian children, adolescents, and young adults. PMID- 29584642 TI - A Visible Light-Driven Minisci-Type Reaction with N-Hydroxyphthalimide Esters. AB - A visible light-promoted protocol for the redox-neutral coupling of N hydroxyphthalimide esters with different N-heterocyclic compounds is described. The reaction proceeds through an alkyl radical intermediate generated by reductive decarboxylation of N-hydroxyphthalimide esters. In contrast to the original Minisci protocol, polyalkylation can largely be avoided. Mechanistic investigations revealed a radical chain mechanism which in some cases can proceed even if no photocatalyst is added. This valuable and functional group-tolerant reaction produces substituted heterocycles in moderate to excellent yield. The use of inexpensive starting materials and LEDs as the light source are key features of this C-C bond formation.

AB - Enamel demineralization is a common problem found in patients using orthodontic devices, such as orthodontic braces. It was found that Streptoccocus mutans growth increases adjacent to orthodontic devices, which may result in caries development. Incorporated antibacterial quaternary ammonium polyethylenimine (QPEI) nanoparticles were previously shown to be highly efficacious against various bacteria. Combining antibacterial materials in orthodontic cement may be advantageous to prevent bacterial outgrowth adjacent to orthodontic brackets. The aim was to evaluate the efficiency of orthodontic cement containing QPEI nanoparticles in reducing S. mutans and Lactobacillus casei outgrowth adjacent to orthodontic brackets. Orthodontic brackets were bonded to the buccal surfaces of extracted lower incisors. The antibacterial effect on S. mutans and L. casei outgrowth of Neobond bracket adhesive orthodontic cement with and without QPEI nanoparticles was compared. The antibacterial effect was evaluated using crystal violet staining and bacterial count (CFU/mL). The teeth in the experimental group, with the QPEI nanoparticles cement, showed significantly lower optical density (OD) values and CFU counts of S. mutans and L. casei than the teeth in the control group (p < 0.05). Based on the results, it can be concluded that orthodontic cement containing QPEI nanoparticles significantly inhibits S. mutans and L. casei growth around orthodontic brackets. PMID- 29584645 TI - An Improved Positioning Method for Two Base Stations in AIS. AB - Resilient position, navigation, and timing (PNT) data is indispensable information in the field of e-navigation. An automatic identification system (AIS) based ranging mode (R-Mode) is put forward to develop a terrestrial backup system in order to overcome the vulnerability of the global navigation satellite system (GNSS). In general, at least three base stations are required in the traditional R-Mode positioning method. However, the geometric distribution of existing base stations is not considered for positioning, as AIS is a communication system. In some cases, a vessel can only receive signals from two base stations. In this paper, an improved position estimation method based on displacement correction is therefore proposed to solve this problem. Compared with the prior displacement correction position estimation (DCPE) method, the proposed method can improve positioning accuracy effectively by adopting a more precise motion model for the vessel, including an accelerated motion and a turning motion model. Moreover, the motion model is employed adaptively to correct the displacement of the vessel. Finally, the proposed method is verified and the performance is analyzed and compared by simulation. This study can extend the application region of AIS R-Mode. PMID- 29584644 TI - On Your Own: Older Adults' Food Choice and Dietary Habits. AB - The United Kingdom, in common with many countries, has an ageing demographic. Changes accompanying ageing can influence food choice and dietary habits. This study explored older adults' perceptions and practices related to dietary behaviour and the factors influencing their food choice in later life. Semi structured focus-group discussions were conducted with 30 individuals (aged 63-90 years) in a UK city. An inductive thematic approach was adopted for data analysis, and 4 themes and 12 sub-themes emerged: age-related changes (lower appetite, food changes, declining physical function); food access (food cost, support with food, maintaining independence); on your own (cooking for one, eating alone, shopping for one); and relationship with food (food variety, eating what you want, dieting). These influenced participants' food acquisition, food preparation and cooking, as well as eating habits. Living alone and its substantial influence, as well as associated social isolation and loneliness, were highlighted in many of the discussions. Given the possible implications for nutritional intake, further work is recommended in this area. Likewise, steps should be taken to improve food access, increase opportunities for commensal eating and, fundamentally, address social isolation and loneliness in the older population. PMID- 29584646 TI - Oleylamine-Mediated Hydrothermal Growth of Millimeter-Long Cu Nanowires and Their Electrocatalytic Activity for Reduction of Nitrate. AB - While high-aspect-ratio metal nanowires are essential for producing nanowire based electrodes of good performance used in electronics and electrocatalysis, the synthesis of millimeter-long Cu nanowires remains a challenge. This work demonstrates an oleylamine-mediated hydrothermal method for synthesis of Cu nanowires with an average diameter of ~80 nm and a length up to several millimeters. An investigation on the role of oleylamine in nanowire formation by mass spectroscopy, small angle X-ray diffraction and transmission electron microscopy reveals that oleylamine serves as a mild reducing agent for slow reduction of Cu(II) to Cu, a complexing agent to form Cu(II)-oleylamine complex for guiding the nanowire growth, as well as a surfactant to generate lamellar phase structure for the formation of nanowire bundles. The growth mechanism of these millimeter-long Cu nanowire bundles is proposed based on the experimental observations. Electrochemical measurements by linear sweep voltammetry indicate that the self-supported nanowire electrode prepared from as-formed Cu nanowire bundles shows high catalytic activity for electroreduction of nitrate in water. PMID- 29584647 TI - FEM Modeling of In-Plane Stress Distribution in Thick Brittle Coatings/Films on Ductile Substrates Subjected to Tensile Stress to Determine Interfacial Strength. AB - The ceramic-metal interface is present in various material structures and devices that are vulnerable to failures, like cracking, which are typically due to their incompatible properties, e.g., thermal expansion mismatch. In failure of these multilayer systems, interfacial shear strength is a good measure of the robustness of interfaces, especially for planar films. There is a widely-used shear lag model and method by Agrawal and Raj to analyse and measure the interfacial shear strength of thin brittle film on ductile substrates. The use of this classical model for a type of polymer derived ceramic coatings (thickness ~18 MUm) on steel substrate leads to high values of interfacial shear strength. Here, we present finite element simulations for such a coating system when it is subjected to in-plane tension. Results show that the in-plane stresses in the coating are non-uniform, i.e., varying across the thickness of the film. Therefore, they do not meet one of the basic assumptions of the classical model: uniform in-plane stress. Furthermore, effects of three significant parameters, film thickness, crack spacing, and Young's modulus, on the in-plane stress distribution have also been investigated. 'Thickness-averaged In-plane Stress' (TIS), a new failure criterion, is proposed for estimating the interfacial shear strength, which leads to a more realistic estimation of the tensile strength and interfacial shear strength of thick brittle films/coatings on ductile substrates. PMID- 29584648 TI - The Nothoaspis amazoniensis Complete Mitogenome: A Comparative and Phylogenetic Analysis. AB - The molecular biology era, together with morphology, molecular phylogenetics, bioinformatics, and high-throughput sequencing technologies, improved the taxonomic identification of Argasidae family members, especially when considering specimens at different development stages, which remains a great difficulty for acarologists. These tools could provide important data and insights on the history and evolutionary relationships of argasids. To better understand these relationships, we sequenced and assembled the first complete mitochondrial genome of Nothoaspis amazoniensis. We used phylogenomics to identify the evolutionary history of this species of tick, comparing the data obtained with 26 complete mitochondrial sequences available in biological databases. The results demonstrated the absence of genetic rearrangements, high similarity and identity, and a close organizational link between the mitogenomes of N. amazoniensis and other argasids analyzed. In addition, the mitogenome had a monophyletic cladistic taxonomic arrangement, encompassed by representatives of the Afrotropical and Neotropical regions, with specific parasitism in bats, which may be indicative of an evolutionary process of cospeciation between vectors and the host.

PMID- 29584650 TI - Identification of a Novel Recombinant Type 2 Porcine Reproductive and Respiratory Syndrome Virus in China. AB - Since the emergence of NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) in China in 2013, PRRSVs have undergone rapid evolution. In this study, a novel variant of PRRSV strain (designated SCcd17) was successfully isolated from piglets with clinical signs in Sichuan Province in China in 2017, and the complete genomic sequence was determined. The genome of this new isolate was 15,015 nucleotides (nt) long, and comparative analysis revealed that SCcd17 exhibited 90.2%, 85.2%, 84.9%, and 84.0% nucleotide similarity to PRRSVs NADC30, JXA1, CH-1a, and VR-2332, respectively. Phylogenetic analysis indicated that the SCcd17 strain was classified into the NADC30-like sub-genotype, in which all the strains contained the unique discontinuous 131-amino acid deletion in nonstructural protein 2 (nsp2) when compared to VR-2332-like viruses. Notably, extensive amino acid substitutions were observed in nsp2 and a unique single amino acid deletion at position 33 of the GP5 is being described for the first time. Strikingly, recombination analysis revealed that SCcd17 was the result of recombination between the NADC30-like, JXA1-like, and VR-2332-like strains at five recombination breakpoints: nsp1alpha (nt 641), nsp3 (nt 5141), nsp10 (nt 9521), open reading frame 3 (ORF3) (nt 12,581), and ORF4 (nt 13,021). The genomic data of SCcd17 will be helpful for understanding the role of genomic recombination in the evolution of PRRSV. PMID- 29584651 TI - Molecular Binding Contributes to Concentration Dependent Acrolein Deposition in Rat Upper Airways: CFD and Molecular Dynamics Analyses. AB - Existing in vivo experiments show significantly decreased acrolein uptake in rats with increasing inhaled acrolein concentrations. Considering that high-polarity chemicals are prone to bond with each other, it is hypothesized that molecular binding between acrolein and water will contribute to the experimentally observed deposition decrease by decreasing the effective diffusivity. The objective of this study is to quantify the probability of molecular binding for acrolein, as well as its effects on acrolein deposition, using multiscale simulations. An image-based rat airway geometry was used to predict the transport and deposition of acrolein using the chemical species model. The low Reynolds number turbulence model was used to simulate the airflows. Molecular dynamic (MD) simulations were used to study the molecular binding of acrolein in different media and at different acrolein concentrations. MD results show that significant molecular binding can happen between acrolein and water molecules in human and rat airways. With 72 acrolein embedded in 800 water molecules, about 48% of acrolein compounds contain one hydrogen bond and 10% contain two hydrogen bonds, which agreed favorably with previous MD results. The percentage of hydrogen-bonded acrolein compounds is higher at higher acrolein concentrations or in a medium with higher polarity. Computational dosimetry results show that the size increase caused by the molecular binding reduces the effective diffusivity of acrolein and lowers the chemical deposition onto the airway surfaces. This result is consistent with the experimentally observed deposition decrease at higher concentrations. However, this size increase can only explain part of the concentration-dependent variation of the acrolein uptake and acts as a concurrent mechanism with the uptake-limiting tissue ration rate. Intermolecular interactions and associated variation in diffusivity should be considered in future dosimetry modeling of high-polarity chemicals such as acrolein.

AB - The recent 2014-2016 West African Ebola virus epidemic underscores the need for the development of novel anti-Ebola therapeutics, due to the high mortality rates of Ebola virus infections and the lack of FDA-approved vaccine or therapy that is available for the prevention and treatment. Traditional Chinese medicines (TCMs) represent a huge reservoir of bioactive chemicals and many TCMs have been shown to have antiviral activities. 373 extracts from 128 TCMs were evaluated using a high throughput assay to screen for inhibitors of Ebola virus cell entry. Extract of Rhodiola rosea displayed specific and potent inhibition against cell entry of both Ebola virus and Marburg virus. In addition, twenty commercial compounds that were isolated from Rhodiola rosea were evaluated using the pseudotyped Ebola virus entry assay, and it was found that ellagic acid and gallic acid, which are two structurally related compounds, are the most effective ones. The activity of the extract and the two pure compounds were validated using infectious Ebola virus. The time-of-addition experiments suggest that, mechanistically, the Rhodiola rosea extract and the effective compounds act at an early step in the infection cycle following initial cell attachment, but prior to viral/cell membrane fusion. Our findings provide evidence that Rhodiola rosea has potent anti-filovirus properties that may be developed as a novel anti-Ebola treatment. PMID- 29584653 TI - Geometrically Nonlinear Field Fracture Mechanics and Crack Nucleation, Application to Strain Localization Fields in Al-Cu-Li Aerospace Alloys. AB - The displacement discontinuity arising between crack surfaces is assigned to smooth densities of crystal defects referred to as disconnections, through the incompatibility of the distortion tensor. In a dual way, the disconnections are defined as line defects terminating surfaces where the displacement encounters a discontinuity. A conservation statement for the crack opening displacement provides a framework for disconnection dynamics in the form of transport laws. A similar methodology applied to the discontinuity of the plastic displacement due to dislocations results in the concurrent involvement of dislocation densities in the analysis. Non-linearity of the geometrical setting is assumed for defining the elastic distortion incompatibility in the presence of both dislocations and disconnections, as well as for their transport. Crack nucleation in the presence of thermally-activated fluctuations of the atomic order is shown to derive from this nonlinearity in elastic brittle materials, without any algorithmic rule or ad hoc material parameter. Digital image correlation techniques applied to the analysis of tensile tests on ductile Al-Cu-Li samples further demonstrate the ability of the disconnection density concept to capture crack nucleation and relate strain localization bands to consistent disconnection fields and to the eventual occurrence of complex and combined crack modes in these alloys.

AB - Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, presenting potential threats to the ecological environment and human health. Sixty-two urban soil samples were collected in the typical semi-arid city of Xi'an in Northwest China. They were analyzed for concentration, pollution, and ecological and health risk of sixteen U.S. Environmental Protection Agency priority PAHs. The total concentrations of the sixteen PAHs (Sigma16PAHs) in the urban soil ranged from 390.6 to 10,652.8 ug/kg with an average of 2052.6 ug/kg. The concentrations of some individual PAHs in the urban soil exceeded Dutch Target Values of Soil Quality and the Sigma16PAHs represented heavy pollution. Pyrene and dibenz[a,h]anthracene had high ecological risk to aquatic/soil organisms, while other individual PAHs showed low ecological risk. The total ecological risk of PAHs to aquatic/soil organisms is classified as moderate. Toxic equivalency quantities (TEQs) of the sixteen PAHs varied between 21.16 and 1625.78 ug/kg, with an average of 423.86 ug/kg, indicating a relatively high toxicity potential. Ingestion and dermal adsorption of soil dust were major pathways of human exposure to PAHs from urban soil. Incremental lifetime cancer risks (ILCRs) of human exposure to PAHs were 2.86 * 10-5 for children and 2.53 * 10-5 for adults, suggesting that the cancer risk of human exposure to PAHs from urban soil is acceptable. PMID- 29584655 TI - Performance of Different Immobilized Lipases in the Syntheses of Short- and Long Chain Carboxylic Acid Esters by Esterification Reactions in Organic Media. AB - Short-chain alkyl esters and sugar esters are widely used in the food, pharmaceutical and cosmetic industries due to their flavor and emulsifying characteristics, respectively. Both compounds can be synthesized via biocatalysis using lipases. This work aims to compare the performance of commercial lipases covalently attached to dry acrylic beads functionalized with oxirane groups (lipases from Candida antarctica type B-IMMCALB-T2-350, Pseudomonas fluorescens IMMAPF-T2-150, and Thermomyces lanuginosus-IMMTLL-T2-150) and a home-made biocatalyst (lipase from Pseudomonas fluorescens adsorbed onto silica coated with octyl groups, named PFL-octyl-silica) in the syntheses of short- and long-chain carboxylic acid esters. Esters with flavor properties were synthetized by esterification of acetic and butyl acids with several alcohols (e.g., ethanol, 1 butanol, 1-hexanol, and isoamyl alcohol), and sugar esters were synthetized by esterification of oleic and lauric acids with fructose and lactose. All biocatalysts showed similar performance in the syntheses of short-chain alkyl esters, with conversions ranging from 88.9 to 98.4%. However, in the syntheses of sugar esters the performance of PFL-octyl-silica was almost always lower than the commercial IMMCALB-T2-350, whose conversion was up to 96% in the synthesis of fructose oleate. Both biocatalysts showed high operational stability in organic media, thus having great potential for biotransformations. PMID- 29584656 TI - Magnetic Graphene Oxide for Dual Targeted Delivery of Doxorubicin and Photothermal Therapy. AB - To develop a pH-sensitive dual targeting magnetic nanocarrier for chemo phototherapy in cancer treatment, we prepared magnetic graphene oxide (MGO) by depositing Fe3O4 magnetic nanoparticles on graphene oxide (GO) through chemical co-precipitation. MGO was modified with polyethylene glycol (PEG) and cetuximab (CET, an epidermal growth factor receptor (EGFR) monoclonal antibody) to obtain MGO-PEG-CET. Since EGFR was highly expressed on the tumor cell surface, MGO-PEG CET was used for dual targeted delivery an anticancer drug doxorubicin (DOX). The physico-chemical properties of MGO-PEG-CET were fully characterized by dynamic light scattering, transmission electron microscopy, X-ray diffraction, Fourier transform Infrared spectroscopy, thermogravimetric analysis, and superconducting quantum interference device. Drug loading experiments revealed that DOX adsorption followed the Langmuir isotherm with a maximal drug loading capacity of 6.35 mg/mg, while DOX release was pH-dependent with more DOX released at pH 5.5 than pH 7.4. Using quantum-dots labeled nanocarriers and confocal microscopy, intracellular uptakes of MGO-PEG-CET by high EGFR-expressing CT-26 murine colorectal cells was confirmed to be more efficient than MGO. This cellular uptake could be inhibited by pre-incubation with CET, which confirmed the receptor-mediated endocytosis of MGO-PEG-CET. Magnetic targeted killing of CT-26 was demonstrated in vitro through magnetic guidance of MGO-PEG-CET/DOX, while the photothermal effect could be confirmed in vivo and in vitro after exposure of MGO PEG-CET to near-infrared (NIR) laser light. In addition, the biocompatibility tests indicated MGO-PEG-CET showed no cytotoxicity toward fibroblasts and elicited minimum hemolysis. In vitro cytotoxicity tests showed the half maximal inhibitory concentration (IC50) value of MGO-PEG-CET/DOX toward CT-26 cells was 1.48 ug/mL, which was lower than that of MGO-PEG/DOX (2.64 ug/mL). The IC50 value could be further reduced to 1.17 ug/mL after combining with photothermal therapy by NIR laser light exposure. Using subcutaneously implanted CT-26 cells in BALB/c mice, in vivo anti-tumor studies indicated the relative tumor volumes at day 14 were 12.1 for control (normal saline), 10.1 for DOX, 9.5 for MGO-PEG-CET/DOX, 5.8 for MGO-PEG-CET/DOX + magnet, and 0.42 for MGO-PEG-CET/DOX + magnet + laser. Therefore, the dual targeting MGO-PEG-CET/DOX could be suggested as an effective drug delivery system for anticancer therapy, which showed a 29-fold increase in therapeutic efficacy compared with control by combining chemotherapy with photothermal therapy. PMID- 29584658 TI - A Robust Real Time Direction-of-Arrival Estimation Method for Sequential Movement Events of Vehicles. AB - Parameters estimation of sequential movement events of vehicles is facing the challenges of noise interferences and the demands of portable implementation. In this paper, we propose a robust direction-of-arrival (DOA) estimation method for the sequential movement events of vehicles based on a small Micro-Electro Mechanical System (MEMS) microphone array system. Inspired by the incoherent signal-subspace method (ISM), the method that is proposed in this work employs multiple sub-bands, which are selected from the wideband signals with high magnitude-squared coherence to track moving vehicles in the presence of wind noise. The field test results demonstrate that the proposed method has a better performance in emulating the DOA of a moving vehicle even in the case of severe wind interference than the narrowband multiple signal classification (MUSIC) method, the sub-band DOA estimation method, and the classical two-sided correlation transformation (TCT) method. PMID- 29584657 TI - The Neurotoxic Role of Extracellular Tau Protein. AB - Tauopathies are a class of neurodegenerative diseases associated with the microtubule-associated protein tau, with Alzheimer's disease (AD) being the most prevalent related disorder. Neurofibrillary tangles (NFTs) are one of the neuropathological hallmarks present in the brains of AD patients. Because NFTs are aberrant intracellular inclusions formed by hyperphosphorylated tau, it was initially proposed that phosphorylated and/or aggregated intracellular tau protein was causative of neuronal death. However, recent studies suggest a toxic role for non-phosphorylated and non-aggregated tau when it is located in the brain extracellular space. In this work, we will discuss the neurotoxic role of extracellular tau as well its involvement in the spreading of tau pathologies. PMID- 29584659 TI - Is What Low-Income Brazilians Are Eating in Popular Restaurants Contributing to Promote Their Health? AB - This study evaluates the healthfulness of the meals offered to and consumed by low-income Brazilians in Popular Restaurants (PR). It is a cross-sectional, exploratory study. The final sample includes 36 PRs, respecting the stratification criteria for each of the five Brazilian regions. To identify the quantity and quality of food consumption, consumers' meals are evaluated. The sample calculation uses a minimum of 41 consumers in each PR. Consumption evaluation is carried out by weighing and direct observation of the meal that each consumer served to his plate. Each dish of the meals had its Technical preparation files (TPF) developed by observing the production and weighing all the ingredients. Evaluations of Energy density (ED), meal's weight components and sodium composition are conducted. Plate's composition is compared to "My plate" guidelines United States Department of Agriculture (USDA). The final sample includes 1771 low-income Brazilians consumers. The plate of PRs consumers is adequate only for the "protein group" in comparison to "My plate". Rice and beans compose more than 50% of the plate's weight, as expected, since it is a Brazilian habit of consumption at lunch. Thus, grains are the major group consumed by PRs consumers. The average ED for all PRs is 1.34 kcal/g. Regarding sodium content, rice and main courses presented the highest values and are classified as high, according to Food and Drug Administration (FDA). Concerning sodium, PRs are putting Brazilian low-income population at risk for chronic diseases. However, in general, PRs are good choices because they promote access to cheap and quality traditional Brazilian foods.

AB - Evidence indicated that socio-environmental factors were associated with occurrence of Japanese encephalitis (JE). This study explored the association of climate and socioeconomic factors with JE (2006-2014) in Shaanxi, China. JE data at the county level in Shaanxi were supplied by Shaanxi Center for Disease Control and Prevention. Population and socioeconomic data were obtained from the China Population Census in 2010 and statistical yearbooks. Meteorological data were acquired from the China Meteorological Administration. A Bayesian conditional autoregressive model was used to examine the association of meteorological and socioeconomic factors with JE. A total of 1197 JE cases were included in this study. Urbanization rate was inversely associated with JE incidence during the whole study period. Meteorological variables were significantly associated with JE incidence between 2012 and 2014. The excessive precipitation at lag of 1-2 months in the north of Shaanxi in June 2013 had an impact on the increase of local JE incidence. The spatial residual variations indicated that the whole study area had more stable risk (0.80-1.19 across all the counties) between 2012 and 2014 than earlier years. Public health interventions need to be implemented to reduce JE incidence, especially in rural areas and after extreme weather. PMID- 29584662 TI - Development of a beta-Lactoglobulin Sensor Based on SPR for Milk Allergens Detection. AB - A sensitive and label-free surface plasmon resonance (SPR) based sensor was developed in this work for the detection of milk allergens. beta-lactoglobulin (BLG) protein was used as the biomarker for cow milk detection. This is to be used directly in final rinse samples of cleaning in-place (CIP) systems of food manufacturers. The affinity assay was optimised and characterised before a standard curve was performed in pure buffer conditions, giving a detection limit of 0.164 ug mL-1 as a direct binding assay. The detection limit can be further enhanced through the use of a sandwich assay and amplification with nanomaterials. However, this was not required here, as the detection limit achieved exceeded the required allergen detection levels of 2 ug mL-1 for beta lactoglobulin. The binding affinities of the polyclonal antibody for BLG, expressed by the dissociation constant (KD), were equal to 2.59 * 10-9 M. The developed SPR-based sensor offers several advantages in terms of label-free detection, real-time measurements, potential on-line system and superior sensitivity when compared to ELISA-based techniques. The method is novel for this application and could be applied to wider food allergen risk management decision(s) in food manufacturing.

Recently available portable MIR spectrometers additionally offer potential for on-site applications, given sufficient spectral data quality. We therefore tested the performance of the Agilent 4300 Handheld FTIR (DRIFT spectra) in comparison to a Bruker Tensor 27 bench-top instrument in terms of (i) spectral quality and measurement noise quantified by wavelet analysis; (ii) accuracy of partial least squares (PLS) calibrations for soil organic carbon (SOC), total nitrogen (N), pH, clay and sand content with a repeated cross-validation analysis; and (iii) key spectral regions for these soil properties identified with a Monte Carlo spectral variable selection approach. Measurements and multivariate calibrations with the handheld device were as good as or slightly better than Bruker equipped with a DRIFT accessory, but not as accurate as with directional hemispherical reflectance (DHR) data collected with an integrating sphere. Variations in noise did not markedly affect the accuracy of multivariate PLS calibrations. Identified key spectral regions for PLS calibrations provided a good match between Agilent and Bruker DHR data, especially for SOC and N. Our findings suggest that portable FTIR instruments are a viable alternative for MIR measurements in the laboratory and offer great potential for on-site applications.

AB - Condition monitoring in polymer composites and structures based on continuous carbon fibers show overwhelming advantages over other potentially competitive sensing technologies in long-gauge measurements due to their great electromechanical behavior and excellent reinforcement property. Although carbon fibers have been developed as strain- or stress-sensing agents in composite structures through electrical resistance measurements, the electromechanical behavior under flexural loads in terms of different loading positions still lacks adequate research, which is the most common situation in practical applications. This study establishes the relationship between the fractional change in electrical resistance of carbon fibers and the external loads at different loading positions along the fibers' longitudinal direction. An approach for real time monitoring of flexural loads at different loading positions was presented simultaneously based on this relationship. The effectiveness and feasibility of the approach were verified by experiments on carbon fiber-embedded three dimensional (3D) printed thermoplastic polymer beam. The error in using the provided approach to monitor the external loads at different loading positions was less than 1.28%. The study fully taps the potential of continuous carbon fibers as long-gauge sensory agents and reinforcement in the 3D-printed polymer structures.

AB - A real-time gas monitoring system based on optical absorption spectroscopy is proposed for localized carbon dioxide (CO2) measurement in respiratory tracts. In this system, a small gas cell is attached to the end of a hollow optical fiber that delivers mid-infrared light with small transmission loss. The diameters of the fiber and the gas cell are smaller than 1.2 mm so that the probe can be inserted into a working channel of common bronchoscopes. The dimensions of the gas cell are designed based on absorption spectra of CO2 standard gases in the 4.2 MUm wavelength region, which are measured using a Fourier-transform infrared spectrometer. A miniature gas cell that is comprised of a stainless-steel tube with slots for gas inlet and a micro-mirror is fabricated. A compact probing system with a quantum cascade laser (QCL) light source is built using a gas cell with a hollow optical fiber for monitoring CO2 concentration. Experimental results using human breaths show the feasibility of the system for in-situ measurement of localized CO2 concentration in human airways.

AB - The current interest of the scientific community for research in the field of calcium sensing in general and on the calcium-sensing Receptor (CaR) in particular is demonstrated by the still increasing number of papers published on this topic. The extracellular calcium-sensing receptor is the best-known G protein-coupled receptor (GPCR) able to sense external Ca2+ changes. Widely recognized as a fundamental player in systemic Ca2+ homeostasis, the CaR is ubiquitously expressed in the human body where it activates multiple signalling pathways. In this review, old and new notions regarding the mechanisms by which extracellular Ca2+ microdomains are created and the tools available to measure them are analyzed. After a survey of the main signalling pathways triggered by the CaR, a special attention is reserved for the emerging concepts regarding CaR function in the heart, CaR trafficking and pharmacology. Finally, an overview on other Ca2+ sensors is provided. PMID- 29584667 TI - Computationally Efficient Automatic Coast Mode Target Tracking Based on Occlusion Awareness in Infrared Images. AB - This paper proposes the automatic coast mode tracking of centroid trackers for infrared images to overcome the target occlusion status. The centroid tracking method, using only the brightness information of an image, is still widely used in infrared imaging tracking systems because it is difficult to extract meaningful features from infrared images. However, centroid trackers are likely to lose the track because they are highly vulnerable to screened status by the clutter or background. Coast mode, one of the tracking modes, maintains the servo slew rate with the tracking rate right before the loss of track. The proposed automatic coast mode tracking method makes decisions regarding entering coast mode by the prediction of target occlusion and tries to re-lock the target and resume the tracking after blind time. This algorithm comprises three steps. The first step is the prediction process of the occlusion by checking both matters which have target-likelihood brightness and which may screen the target despite different brightness. The second step is the process making inertial tracking commands to the servo. The last step is the process of re-locking a target based on the target modeling of histogram ratio. The effectiveness of the proposed algorithm is addressed by presenting experimental results based on computer simulation with various test imagery sequences compared to published tracking algorithms. The proposed algorithm is tested under a real environment with a naval electro-optical tracking system (EOTS) and airborne EO/IR system.

AB - Vibrio cholerae ATP-binding cassette transporter VcaM (V. cholerae ABC multidrug resistance pump) has previously been shown to confer resistance to a variety of medically important drugs. In this study, we set to analyse its properties both in vitro in detergent-solubilised state and in vivo to differentiate its dependency on auxiliary proteins for its function. We report the first detailed kinetic parameters of purified VcaM and the rate of phosphate (Pi) production. To determine the possible functional dependencies of VcaM on the tripartite efflux pumps we then utilized different E. coli strains lacking the principal secondary transporter AcrB (Acriflavine resistance protein), as well as cells lacking the outer membrane factor (OMF) TolC (Tolerance to colicins). Consistent with the ATPase function of VcaM we found it to be susceptible to sodium orthovanadate (NaOV), however, we also found a clear dependency of VcaM function on TolC. Inhibitors targeting secondary active transporters had no effects on either VcaM conferred resistance or Hoechst 33342 accumulation, suggesting that VcaM might be capable of engaging with the TolC-channel without periplasmic mediation by additional transporters. Our findings are indicative of VcaM being capable of a one-step substrate translocation from cytosol to extracellular space utilising the TolC-channel, making it the only multidrug ABC-transporter outside of the MacB-family with demonstrable TolC-dependency.

AB - Fibroblast growth factor receptor 1 (FGFR1) has become a potential target for the treatment of cancer. Designing FGFR1-selective inhibitors remains fundamental to the development of anti-cancer drugs because of highly sequential homology among FGFR subtypes. In present work, four inhibitors were examined with intermolecular interaction patterns with FGFR1 and FGFR4, respectively, for the exploration of binding mechanisms by applying a combined approach of computational techniques, including flexible docking, binding site analyses, electronic structure computations, molecular dynamic simulations, and binding free energy predictions. Molecular simulation-predicted binding conformations and pharmacophoric features of these molecules in the active pocket of either FGFR1 or FGFR4. MMPB(GB)SA calculated binding free energies were accordant with the ordering of their tested potency values. Furthermore, in silico mutations of two residues (FGFR1: Tyr563 and Ser565) were also performed to check their impact on ligand binding by applying MD simulations and binding free energy calculations. The present studies may provide a structural understanding of the FGFR1-selective mechanism. The viewpoints from computational simulations would be valuable guidelines for the development of novel FGFR1-selective inhibitors. PMID- 29584669 TI - Small Molecule Catalysts with Therapeutic Potential. AB - Catalysts are employed in many areas of research and development where they combine high efficiency with often astonishing selectivity for their respective substrates. In biology, biocatalysts are omnipresent. Enzymes facilitate highly controlled, sophisticated cellular processes, such as metabolic conversions, sensing and signalling, and are prominent targets in drug development. In contrast, the therapeutic use of catalysts per se is still rather limited. Recent research has shown that small molecule catalytic agents able to modulate the redox state of the target cell bear considerable promise, particularly in the context of inflammatory and infectious diseases, stroke, ageing and even cancer. Rather than being "active" on their own in a more traditional sense, such agents develop their activity by initiating, promoting, enhancing or redirecting reactions between biomolecules already present in the cell, and their activity therefore depends critically on the predisposition of the target cell itself. Redox catalysts, for instance, preferably target cells with a distinct sensitivity towards changes in an already disturbed redox balance and/or increased levels of reactive oxygen species. Indeed, certain transition metal, chalcogen and quinone agents may activate an antioxidant response in normal cells whilst at the same time triggering apoptosis in cancer cells with a different pre existing "biochemical redox signature" and closer to the internal redox threshold. In pharmacy, catalysts therefore stand out as promising lead structures, as sensor/effector agents which are highly effective, fairly selective, active in catalytic, i.e., often nanomolar concentrations and also very flexible in their structural design.

AB - The nuclear factor erythroid-derived 2-related factor 2 (Nrf2) is a key regulator of gene expression during oxidative stress and drug detoxification. Thus, identifying Nrf2 activators to protect from possible cell damage is necessary. In this study, we investigated whether E-p-methoxycinnamoyl-alpha-l-rhamnopyranosyl ester (MCR), a phenylpropanoid isolated from Scrophularia buergeriana, can activate Nrf2 signaling in human keratinocytes (HaCaT). First, we determined the dose- and time-dependent effects of MCR on the expression and activity of Nrf2. The antioxidant response element-luciferase reporter assay and western blot analysis results showed that MCR markedly induced Nrf2 activity and its protein expression, respectively. Further, MCR increased both the mRNA and protein levels of heme-oxygenase-1, one of the Nrf2 target genes, in the cells. Interestingly, we found that Nrf2 stability was remarkably enhanced by MCR. Furthermore, ubiquitin-dependent proteasomal degradation of Nrf2 was significantly reduced by MCR. Thus, MCR might afford skin protection by enhancing Nrf2 stability or by blocking its proteasomal degradation. PMID- 29584672 TI - Charge-Controlled Synthetic Hyaluronan-Based Cell Matrices. AB - The extracellular matrix (ECM) represents a highly charged and hydrated network in which different cells in vertebrate tissues are embedded. Hydrogels as minimal ECM mimetics with a controlled chemistry offer the opportunity to vary material properties by varying the negative network charge. In this paper, a synthetic biology model of the ECM based on natural and highly negatively charged polyelectrolyte hyaluronic acid (HA) is characterized with specific emphasis on its charge-related bioactivity. Therefore, the thiol-Michael addition click reaction is used to produce HA hydrogels with defined network structure and charge density. The presented hydrogels show enzymatic degradability and cell attachment. These properties depend on both covalent and electrostatic interactions within the hydrogel network. Furthermore, no unspecific or specific attachment of proteins to the presented hydrogels is observed. In addition, these fundamental insights into charge-related ECM behavior and the influence of electrostatic properties could also lead to innovations in existing biomedical products. PMID- 29584674 TI - Investigating Effects of Fused-Deposition Modeling (FDM) Processing Parameters on Flexural Properties of ULTEM 9085 using Designed Experiment. AB - Fused-deposition modeling (FDM), one of the additive manufacturing (AM) technologies, is an advanced digital manufacturing technique that produces parts by heating, extruding and depositing filaments of thermoplastic polymers. The properties of FDM-produced parts apparently depend on the processing parameters. These processing parameters have conflicting advantages that need to be investigated. This article focuses on an investigation into the effect of these parameters on the flexural properties of FDM-produced parts. The investigation is carried out on high-performance ULTEM 9085 material, as this material is relatively new and has potential application in the aerospace, military and automotive industries. Five parameters: air gap, raster width, raster angle, contour number, and contour width, with a full factorial design of the experiment, are considered for the investigation. From the investigation, it is revealed that raster angle and raster width have the greatest effect on the flexural properties of the material. The optimal levels of the process parameters achieved are: air gap of 0.000 mm, raster width of 0.7814 mm, raster angle of 0 degrees , contour number of 5, and contour width of 0.7814 mm, leading to a flexural strength of 127 MPa, a flexural modulus of 2400 MPa, and 0.081 flexural strain. PMID- 29584673 TI - Effects of the Combination of Gliotoxin and Adriamycin on the Adriamycin Resistant Non-Small-Cell Lung Cancer A549 Cell Line. AB - Acquired drug resistance constitutes an enormous hurdle in cancer treatment, and the search for effective compounds against resistant cancer is still advancing. Marine organisms are a promising natural resource for the discovery and development of anticancer agents. In this study, we examined whether gliotoxin (GTX), a secondary metabolite isolated from marine-derived Aspergillus fumigatus, inhibits the growth of adriamycin (ADR)-resistant non-small-cell lung cancer (NSCLC) cell lines A549/ADR. We investigated the effects of GTX on A549/ADR cell viability with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and the induction of apoptosis in A549/ADR cells treated with GTX via fluorescence-activated cell sorting analysis, Hoechst staining, annexin V/propidium iodide staining, tetraethylbenzimidazolylcarbocyanine iodide (JC-1) staining, and western blotting. We found that GTX induced apoptosis in A549/ADR cells through the mitochondria-dependent pathway by disrupting mitochondrial membrane potential and activating p53, thereby increasing the expression levels of p21, p53 upregulated modulator of apoptosis (PUMA), Bax, cleaved poly (ADP ribose) polymerase (PARP), and cleaved caspase-9. More importantly, we discovered that GTX works in conjunction with ADR to exert combinational effects on A549/ADR cells. In conclusion, our results suggest that GTX may have promising effects on ADR-resistant NSCLC cells by inducing mitochondria-dependent apoptosis and through the combined effects of sequential treatment with ADR. PMID- 29584675 TI - Optical Third Harmonic Generation Using Nickel Nanostructure-Covered Microcube Structures. AB - We investigated the optical third harmonic generation (THG) signal from nanostructure-covered microcubes on Ni. We found that the hierarchical structures greatly change the third-order optical nonlinearity of the metallic surface. While the symmetry and lightning rod (LR) effects on microstructures did not significantly influence the THG, the localized surface plasmon (LSP) effect on the nanostructures enhanced it. By removing the nanostructures on the hierarchical structures, THG intensity could be strongly suppressed. In the present paper, we also discuss the mechanism that enhances THG in nano/micro structures. PMID- 29584676 TI - Phase Transition of Single-Layer Molybdenum Disulfide Nanosheets under Mechanical Loading Based on Molecular Dynamics Simulations. AB - The single-layer molybdenum disulfide (SLMoS2) nanosheets have been experimentally discovered to exist in two different polymorphs, which exhibit different electrical properties, metallic or semiconducting. Herein, molecular dynamics (MD) simulations of nanoindentation and uniaxial compression were conducted to investigate the phase transition of SLMoS2 nanosheets. Typical load deflection curves, stress-strain curves, and local atomic structures were obtained. The loading force decreases sharply and then increases again at a critical deflection under the nanoindentation, which is inferred to the phase transition. In addition to the layer thickness, some related bond lengths and bond angles were also found to suddenly change as the phase transition occurs. A bell-like hollow, so-called residual deformation, was found to form, mainly due to the lattice distortion around the waist of the bell. The effect of indenter size on the residual hollow was also analyzed. Under the uniaxial compression along the armchair direction, a different phase transition, a uniformly quadrilateral structure, was observed when the strain is greater than 27.7%. The quadrilateral structure was found to be stable and exhibit metallic conductivity in view of the first-principle calculation. PMID- 29584677 TI - Indentation Behavior and Mechanical Properties of Tungsten/Chromium co-Doped Bismuth Titanate Ceramics Sintered at Different Temperatures. AB - A sort of tungsten/chromium(W/Cr) co-doped bismuth titanate (BIT) ceramics (Bi4Ti2.95W0.05O12.05 + 0.2 wt % Cr2O3, abbreviate to BTWC) are ordinarily sintered between 1050 and 1150 degrees C, and the indentation behavior and mechanical properties of ceramics sintered at different temperatures have been investigated by both nanoindentation and microindentation technology. Firstly, more or less Bi2Ti2O7 grains as the second phase were found in BTWC ceramics, and the grain size of ceramics increased with increase of sintering temperatures. A nanoindentation test for BTWC ceramics reveals that the testing hardness of ceramics decreased with increase of sintering temperatures, which could be explained by the Hall-Petch equation, and the true hardness could be calculated according to the pressure-state-response (PSR) model considering the indentation size effect, where the value of hardness depends on the magnitude of load. While, under the application of microsized Vickers, the sample sintered at a lower temperature (1050 degrees C) gained four linearly propagating cracks, however, they were observed to shorten in the sample sintered at a higher temperature (1125 degrees C). Moreover, both the crack deflection and the crack branching existed in the latter. The hardness and the fracture toughness of BTWC ceramics presented a contrary variational tendency with increase of sintering temperatures. A high sintering tends to get a lower hardness and a higher fracture toughness, which could be attributed to the easier plastic deformation and the stronger crack inhibition of coarse grains, respectively, as well as the toughening effect coming from the second phase. PMID- 29584678 TI - Experimental Investigation of the Effect of Hydrogen on Fracture Toughness of 2.25Cr-1Mo-0.25V Steel and Welds after Annealing. AB - Hydrogen embrittlement (HE) is a critical issue that hinders the reliability of hydrogenation reactors. Hence, it is of great significance to investigate the effect of hydrogen on fracture toughness of 2.25Cr-1Mo-0.25V steel and weld. In this work, the fracture behavior of 2.25Cr-1Mo-0.25V steel and welds was studied by three-point bending tests under hydrogen-free and hydrogen-charged conditions. The immersion charging method was employed to pre-charge hydrogen inside specimen and the fracture toughness of these joints was evaluated quantitatively. The microstructure and grain size of the specimens were observed by scanning electron microscopy (SEM) and by metallurgical microscopy to investigate the HE mechanisms. It was found that fracture toughness for both the base metal (BM) and the weld zone (WZ) significantly decreased under hydrogen-charged conditions due to the coexistence of the hydrogen-enhanced decohesion (HEDE) and hydrogen enhanced localized plasticity (HELP) mechanisms. Moreover, the formation and growth of primary voids were observed in the BM, leading to a superior fracture toughness. In addition, the BM compared to the WZ shows superior resistance to HE because the finer grain size in the BM leads to a larger grain boundary area, thus distributing more of the diffusive hydrogen trapped in the grain boundary and reducing the hydrogen content. PMID- 29584679 TI - An Extended Chemical Plant Environmental Protection Game on Addressing Uncertainties of Human Adversaries. AB - Chemical production activities in industrial districts pose great threats to the surrounding atmospheric environment and human health. Therefore, developing appropriate and intelligent pollution controlling strategies for the management team to monitor chemical production processes is significantly essential in a chemical industrial district. The literature shows that playing a chemical plant environmental protection (CPEP) game can force the chemical plants to be more compliant with environmental protection authorities and reduce the potential risks of hazardous gas dispersion accidents. However, results of the current literature strictly rely on several perfect assumptions which rarely hold in real world domains, especially when dealing with human adversaries. To address bounded rationality and limited observability in human cognition, the CPEP game is extended to generate robust schedules of inspection resources for inspection agencies. The present paper is innovative on the following contributions: (i) The CPEP model is extended by taking observation frequency and observation cost of adversaries into account, and thus better reflects the industrial reality; (ii) Uncertainties such as attackers with bounded rationality, attackers with limited observation and incomplete information (i.e., the attacker's parameters) are integrated into the extended CPEP model; (iii) Learning curve theory is employed to determine the attacker's observability in the game solver. Results in the case study imply that this work improves the decision-making process for environmental protection authorities in practical fields by bringing more rewards to the inspection agencies and by acquiring more compliance from chemical plants. PMID- 29584680 TI - Development and Characterisation of a Human Chronic Skin Wound Cell Line-Towards an Alternative for Animal Experimentation. AB - Background: Chronic skin wounds are a growing financial burden for healthcare providers, causing discomfort/immobility to patients. Whilst animal chronic wound models have been developed to allow for mechanistic studies and to develop/test potential therapies, such systems are not good representations of the human chronic wound state. As an alternative, human chronic wound fibroblasts (CWFs) have permitted an insight into the dysfunctional cellular mechanisms that are associated with these wounds. However, such cells strains have a limited replicative lifespan and therefore a limited reproducibility/usefulness. Objectives: To develop/characterise immortalised cell lines of CWF and patient matched normal fibroblasts (NFs). Methods and Results: Immortalisation with human telomerase resulted in both CWF and NF proliferating well beyond their replicative senescence end-point (respective cell strains senesced as normal). Gene expression analysis demonstrated that, whilst proliferation-associated genes were up-regulated in the cell lines (as would be expected), the immortalisation process did not significantly affect the disease-specific genotype. Immortalised CWF (as compared to NF) also retained a distinct impairment in their wound repopulation potential (in line with CWF cell strains). Conclusions: These novel CWF cell lines are a credible animal alternative and could be a valuable research tool for understanding both the aetiology of chronic skin wounds and for therapeutic pre-screening. PMID- 29584681 TI - Evaluating Community Partnerships Addressing Community Resilience in Los Angeles, California. AB - Community resilience has grown in importance in national disaster response and recovery efforts. However, measurement of community resilience, particularly the content and quality of relationships aimed at improving resilience, is lacking. To address this gap, we used a social network survey to measure the number, type, and quality of relationships among organizations participating in 16 coalitions brought together to address community resilience in the Los Angeles Community Disaster Resilience project. These coalitions were randomized to one of two approaches (community resilience or preparedness). Resilience coalitions received training and support to develop these partnerships and implement new activities. Both coalition types received expert facilitation by a public health nurse or community educator. We also measured the activities each coalition engaged in and the extent to which partners participated in these activities at two time points. We found that the community resilience coalitions were initially larger and had lower trust among members than the preparedness communities. Over time, these trust differences dissipated. While both coalitions grew, the resilience community coalitions maintained their size difference throughout the project. We also found differences in the types of activities implemented by the resilience communities; these differences were directly related to the trainings provided. This information is useful to organizations seeking guidance on expanding the network of community-based organizations that participate in community resilience activities. PMID- 29584682 TI - Fabrication of Amine-Modified Magnetite-Electrochemically Reduced Graphene Oxide Nanocomposite Modified Glassy Carbon Electrode for Sensitive Dopamine Determination. AB - Amine-modified magnetite (NH2-Fe3O4)/reduced graphene oxide nanocomposite modified glassy carbon electrodes (NH2-Fe3O4/RGO/GCEs) were developed for the sensitive detection of dopamine (DA). The NH2-Fe3O4/RGO/GCEs were fabricated using a drop-casting method followed by an electrochemical reduction process. The surface morphologies, microstructure and chemical compositions of the NH2-Fe3O4 nanoparticles (NPs), reduced graphene oxide (RGO) sheets and NH2-Fe3O4/RGO nanocomposites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-Ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The electrochemical behaviors of DA on the bare and modified GCEs were investigated in phosphate buffer solution (PBS) by cyclic voltammetry (CV). Compared with bare electrode and RGO/GCE, the oxidation peak current (ipa) on the NH2-Fe3O4/RGO/GCE increase significantly, owing to the synergistic effect between NH2-Fe3O4 NPs and RGO sheets. The oxidation peak currents (ipa) increase linearly with the concentrations of DA in the range of 1 * 10-8 mol/L - 1 * 10-7 mol/L, 1 * 10-7 mol/L - 1 * 10-6 mol/L and 1 * 10-6 mol/L - 1 * 10-5 mol/L. The detection limit is (4.0 +/- 0.36) *10-9 mol/L (S/N = 3). Moreover, the response peak currents of DA were hardly interfered with the coexistence of ascorbic acid (AA) and uric acid (UA). The proposed NH2-Fe3O4/RGO/GCE is successfully applied to the detection of dopamine hydrochloride injections with satisfactory results. Together with low cost, facile operation, good selectivity and high sensitivity, the NH2-Fe3O4/RGO/GCEs have tremendous prospects for the detection of DA in various real samples. PMID- 29584683 TI - Mechanical and Thermal Properties of Dental Composites Cured with CAD/CAM Assisted Solid-State Laser. AB - Over the last three decades, it has been frequently reported that the properties of dental restorative composites cured with argon laser are similar or superior to those achieved with conventional halogen and light emitting diode (LED) curing units. Whereas laser curing is not dependent on the distance between the curing unit and the material, such distance represents a drawback for conventional curing units. However, a widespread clinical application of this kind of laser remains difficult due to cost, heavy weight, and bulky size. Recently, with regard to the radiation in the blue region of the spectrum, powerful solid-state lasers have been commercialized. In the current research, CAD (computer-aided design)/CAM (computer-aided manufacturing) assisted solid-state lasers were employed for curing of different dental restorative composites consisting of micro- and nanoparticle-reinforced materials based on acrylic resins. Commercial LED curing units were used as a control. Temperature rise during the photopolymerisation process and bending properties were measured. By providing similar light energy dose, no significant difference in temperature rise was observed when the two light sources provided similar intensity. In addition, after 7 days since curing, bending properties of composites cured with laser and LED were similar. The results suggested that this kind of laser would be suitable for curing dental composites, and the curing process does not suffer from the tip to-tooth distance. PMID- 29584684 TI - A New Lignanamide from the Root of Lycium yunnanense Kuang and Its Antioxidant Activity. AB - A new lignanamide (1), lyciumamide K, together with four known analogues (2-5), was isolated from the root of Lycium yunnanense Kuang. Based on HR-ESI-MS, NMR spectral data and quantum chemistry ECD calculations, the structure of this new compound was confirmed, including its absolute configuration. Evaluation of the antioxidant activity of compounds 1-5 in the oxygen radical absorption capacity (ORAC) assay showed that they all exhibited significant antioxidant activities. Particularly, compound 1 showed the best activity with ORAC values (U/mol) of 7.90 +/- 0.52. Thus, the new lignanamide may be a good source of bioavtive and protective compounds. PMID- 29584686 TI - In-Cabin Air Quality during Driving and Engine Idling in Air-Conditioned Private Vehicles in Hong Kong. AB - Many people spend lengthy periods each day in enclosed vehicles in Hong Kong. However, comparably limited data is available about in-cabin air quality in air conditioned private vehicles, and the car usage that may affect the air quality. Fifty-one vehicles were tested for particulate matter (PM0.3 and PM2.5), total volatile organic compounds (TVOCs), carbon monoxide (CO), carbon dioxide (CO2), airborne bacteria, and fungi levels during their routine travel journey. Ten of these vehicles were further examined for PM0.3, PM2.5, TVOCs, CO, and CO2 during engine idling. In general, during driving PM2.5 levels in-cabin reduced overtime, but not PM0.3. For TVOCs, 24% vehicles exceeded the recommended Indoor Air Quality (IAQ) level in offices and public places set by the Hong Kong Environmental Protection Department. The total volatile organic compounds (TVOC) concentration positively correlated with the age of the vehicle. Carbon monoxide (CO) levels in all of the vehicles were lower than the IAQ recommendation, while 96% vehicles exceeded the recommended CO2 level of 1000 ppmv; 16% vehicles >5000 ppmv. Microbial counts were relatively low. TVOCs levels at idle engine were higher than that during driving. Although the time we spend in vehicles is short, the potential exposure to high levels of pollutants should not be overlooked. PMID- 29584685 TI - Characterization of Human Type C Enterotoxin Produced by Clinical S. epidermidis Isolates. AB - Staphylococcal Enterotoxins (SEs) are superantigens (SAg) originally produced by S. aureus, but their presence in coagulase negative staphylococci (CNS) has long been suspected. This study aims to better characterize a novel C-like enterotoxin expressed by clinical S. epidermidis strains, called SECepi. We isolated and characterized SECepi for its molecular and functional properties. The toxin was structurally modeled according to its significant similarity with S. aureus SEC3. Most of SEC amino acid residues important for the formation of the trimolecular Major Histocompatibility Complex II MHCII-SEC-T Cell Receptor TCR complex are conserved in SECepi. The functional properties of SECepi were estimated after cloning, expression in E. coli, and purification. The recombinant SECepi toxin exhibits biological characteristics of a SAg including stimulation of human T cell mitogenicity, inducing and releasing high cytokines levels: IL-2, -4, -6, 8, -10, IFN-gamma, TNF-alpha and GM-CSF at a dose as low as 3.7 pM. Compared to SECaureus, the production of pro-sepsis cytokine IL-6 is significantly higher with SECepi-activated lymphocytes. Furthermore, SECepi is stable to heat, pepsin or trypsin hydrolysis. The SECepi superantigen produced by CNS is functionally very close to that of S. aureus, possibly inducing a systemic inflammatory response at least comparable to that of SECaureus, and may account for S. epidermidis pathogenicity. PMID- 29584687 TI - Association between Resistin Gene Polymorphisms and Atopic Dermatitis. AB - Atopic dermatitis (AD) is a chronic, relapsing, and inflammatory skin disorder. It is characterized by an inappropriate skin barrier function, allergen sensitization, and recurrent skin infections. Resistin is an adipokine expressed mainly in macrophages and monocytes; it has a role in the inflammatory process and is associated with multiple inflammatory human diseases; however, only few studies linked resistin to atopic dermatitis. This study tested the association between G>A (rs3745367) and C>T (rs3219177) single nucleotide polymorphisms (SNPs) of the RETN gene with atopic dermatitis. In addition, it explored the relationship between serum resistin protein and atopic dermatitis. To achieve objectives of this study, 162 atopic dermatitis patients and 161 healthy participants were recruited in the study. A significant association was detected between rs3745367 and atopic dermatitis with age and gender specificity (p < 0.05), while no significant association between rs3219177 and atopic dermatitis was found (p > 0.05). For the serum resistin levels, a significant decrease was indicated in atopic dermatitis patients compared to healthy subjects (p < 0.05). In conclusion, rs3745367 may play a gender and age-specific role in atopic dermatitis. In addition, the significant decrease in the resistin protein level confirmed this association.

The aim of this study was to develop therapeutic MSCs with a suicide gene that is induced by an artificial stimulus, to validate therapeutic gene expression, and to monitor the MSC therapy for colon cancer using optical molecular imaging. For our study, we designed the Tet-On system using a retroviral vector and developed a response plasmid RetroX-TRE (tetracycline response element) expressing a mutant form of herpes simplex virus thymidine kinase (HSV1-sr39TK) with dual reporters (eGFP Fluc2). Bone marrow-derived MSCs were transduced using a RetroX-Tet3G (Clontech, CA, USA) regulatory plasmid and RetroX-TRE-HSV1-sr39TK-eGFP-IRES-Fluc2, for a system with a Tet-On (MSC-Tet-TK/Fluc2 or MSC-Tet-TK) or without a Tet-On (MSC TK/Fluc2 or MSC-TK) function. Suicide gene engineered MSCs were co-cultured with colon cancer cells (CT26/Rluc) in the presence of the prodrug ganciclovir (GCV) after stimulation with or without doxycycline (DOX). Treatment efficiency was monitored by assessing Rluc (CT26/Rluc) and Fluc (MSC-Tet-TK and MSC-TK) activity using optical imaging. The bystander effect of therapeutic MSCs was confirmed in CT26/Rluc cells after GCV treatment. Rluc activity in CT26/Rluc cells decreased significantly with GCV treatment of DOX(+) cells (p < 0.05 and 0.01) whereas no significant changes were observed in DOX(-) cells. In addition, Fluc activity in also decreased significantly with DOX(+) MSC-Tet-TK cells, but no signal was observed in DOX(-) cells. In addition, an MSC-TK bystander effect was also confirmed. We assessed therapy with this system in a colon cancer xenograft model (CT26/Rluc). We successfully transduced cells and developed a Tet-On system with the suicide gene HSV1-sr39TK. Our results confirmed the therapeutic efficiency of a suicide gene with the Tet-On system for colon cancer. In addition, our results provide an innovative therapeutic approach using the Tet-On system to eradicate tumors by administration of MSC-Tet-TK cells with DOX and GCV.

AB - The Japanese fermented beverage, homemade kefir, contains six lactic acid bacteria: Lactococcus. lactis subsp. Lactis, Lactococcus. lactis subsp. Cremoris, Lactococcus. Lactis subsp. Lactis biovar diacetylactis, Lactobacillus plantarum, Leuconostoc meseuteroides subsp. Cremoris and Lactobacillus casei. In this study, we found that a mixture of the six lactic acid bacteria from kefir increased the cytotoxicity of human natural killer KHYG-1 cells to human chronic myelogenous leukemia K562 cells and colorectal tumor HCT116 cells. Furthermore, levels of mRNA expression and secretion of IFN-gamma (interferon gamma) increased in KHYG-1 cells that had been treated with the six lactic acid bacteria mixture from kefir. The results suggest that the six lactic acid bacteria mixture from kefir has strong effects on natural immunity and tumor cell cytotoxicity.

AB - New amphiphilic liquid crystal (LC) polycarbonate block copolymers containing side-chain cholesteryl units were synthesized. Their structure, thermal stability, and LC phase behavior were characterized with Fourier transform infrared (FT-IR) spectrum, 1H NMR, gel permeation chromatographic (GPC), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), polarizing optical microscope (POM), and XRD methods. The results demonstrated that the LC copolymers showed a double molecular arrangement of a smectic A phase at room temperature. With the elevating of LC unit content in such LC copolymers, the corresponding properties including decomposition temperature (Td), glass temperature (Tg), and isotropic temperature (Ti) increased. The LC copolymers showed pH-responsive self-assembly behavior under the weakly acidic condition, and with more side-chain LC units, the self-assembly process was faster, and the formed particle size was smaller. It indicated that the self-assembly driving force was derived from the orientational ability of LC. The particle size and morphologies of self-assembled microspheres loaded with doxorubicin (DOX), together with drug release tracking, were evaluated by dynamic light scattering (DLS), SEM, and UV-vis spectroscopy. The results showed that DOX could be quickly released in a weakly acidic environment due to the pH response of the self assembled microspheres. This would offer a new strategy for drug delivery in clinic applications. PMID- 29584689 TI - Extracellular Matrix as a Regulator of Epidermal Stem Cell Fate. AB - Epidermal stem cells reside within the specific anatomic location, called niche, which is a microenvironment that interacts with stem cells to regulate their fate. Regulation of many important processes, including maintenance of stem cell quiescence, self-renewal, and homeostasis, as well as the regulation of division and differentiation, are common functions of the stem cell niche. As it was shown in multiple studies, extracellular matrix (ECM) contributes a lot to stem cell niches in various tissues, including that of skin. In epidermis, ECM is represented, primarily, by a highly specialized ECM structure, basement membrane (BM), which separates the epidermal and dermal compartments. Epidermal stem cells contact with BM, but when they lose the contact and migrate to the overlying layers, they undergo terminal differentiation. When considering all of these factors, ECM is of fundamental importance in regulating epidermal stem cells maintenance, proper mobilization, and differentiation. Here, we summarize the remarkable progress that has recently been made in the research of ECM role in regulating epidermal stem cell fate, paying special attention to the hair follicle stem cell niche. We show that the destruction of ECM components impairs epidermal stem cell morphogenesis and homeostasis. A deep understanding of ECM molecular structure as well as the development of in vitro system for stem cell maintaining by ECM proteins may bring us to developing new approaches for regenerative medicine. PMID- 29584692 TI - Tribological Behavior and the Mild-Severe Wear Transition of Mg97Zn1Y2 Alloy with a LPSO Structure Phase. AB - Dry friction and wear tests were performed on as-cast Mg97Zn1Y2 alloy using a pin on-disc configuration. Coefficients of friction and wear rates were measured as a function of applied load at sliding speeds of 0.2, 0.8 and 3.0 m/s. The wear mechanisms were identified in the mild and severe wear regimes by means of morphological observation and composition analysis of worn surfaces using scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS). Analyses of microstructure and hardness changes in subsurfaces verified the microstructure transformation from the deformed to the dynamically recrystallized, and properties changed from the strain hardening to dynamic crystallization (DRX) softening before and after the mild-severe wear transition. The mild-severe wear transition can be determined by a proposed contact surface DRX temperature criterion, from which the critical DRX temperatures at different sliding speeds are calculated using DRX dynamics; hence transition loads can also be calculated using a transition load model. The calculated transition loads are in good agreement with the measured ones, demonstrating the validity and applicability of the contact surface DRX temperature criterion. PMID- 29584694 TI - Subsurface Damage in Polishing Process of Silicon Carbide Ceramic. AB - Subsurface damage (SSD) in the polishing process of silicon carbide (SiC) ceramic presents one of the most significant challenges for practical applications. In this study, the theoretical models of SSD depth are established on the basis of the material removal mechanism and indentation fracture mechanics in the SiC ceramic polishing process. In addition, the three-dimensional (3D) models of single grit polishing are also developed by using the finite element simulation; thereby, the dynamic effects of different process parameters on SSD depth are analyzed. The results demonstrate that the material removal was mainly in brittle mode when the cutting depth was larger than the critical depth of the brittle material. The SSD depth increased as the polishing depth and abrasive grain size increased, and decreased with respect to the increase in polishing speed. The experimental results suggested a good agreement with the theoretical simulation results in terms of SSD depth as a function of polishing depth, spindle speed, and abrasive grain size. This study provides a mechanistic insight into the dependence of SSD on key operational parameters in the polishing process of SiC ceramic.

AB - In the degradation process, the randomness and multiplicity of variables are difficult to describe by mathematical models. However, they are common in engineering and cannot be neglected, so it is necessary to study this issue in depth. In this paper, the copper bending pipe in seawater piping systems is taken as the analysis object, and the time-variant reliability is calculated by solving the interference of limit strength and maximum stress. We did degradation experiments and tensile experiments on copper material, and obtained the limit strength at each time. In addition, degradation experiments on copper bending pipe were done and the thickness at each time has been obtained, then the response of maximum stress was calculated by simulation. Further, with the help of one kind of Monte Carlo method we propose, the time-variant reliability of copper bending pipe was calculated based on the stochastic degradation process and interference theory. Compared with traditional methods and verified by maintenance records, the results show that the time-variant reliability model based on the stochastic degradation process proposed in this paper has better applicability in the reliability analysis, and it can be more convenient and accurate to predict the replacement cycle of copper bending pipe under seawater active corrosion. PMID- 29584693 TI - Is Matrix Gla Protein Associated with Vascular Calcification? A Systematic Review. AB - Specific patient cohorts are at increased risk of vascular calcification. Functional matrix-gla protein (MGP), a tissue-derived vitamin K dependent protein, is reported to be an important inhibitor of vascular calcification and may have clinical potential to modify the progression of vascular calcification through regulation of functional MGP fractions. This systematic review examines twenty-eight studies which assess the relationship between circulating protein expressions of MGP species and vascular calcification in different arterial beds. The included studies examined participants with atherosclerosis, chronic kidney disease (CKD), diabetes, healthy participants, vitamin K supplementation, measured plasma vitamin K levels and vitamin K antagonist usage. The current review reports conflicting results regarding MGP fractions with respect to local calcification development indicating that a multifaceted relationship exists between the MGP and calcification. A primary concern regarding the studies in this review is the large degree of variability in the calcification location assessed and the fraction of MGP measured. This review suggests that different underlying molecular mechanisms can accelerate local disease progression within the vasculature, and specific circulating fractions of MGP may be influenced differently depending on the local disease states related to vascular calcification development. Further studies examining the influence of non functional MGP levels, with respect to specific calcified arterial beds, are warranted. PMID- 29584696 TI - beta4 and beta6 Integrin Expression Is Associated with the Subclassification and Clinicopathological Features of Intrahepatic Cholangiocarcinoma. AB - Intrahepatic cholangiocarcinoma (ICC) is a heterogeneous group of cancers of the intrahepatic biliary tract. However, few studies have evaluated integrin expression according to an ICC subgroup. We immunohistochemically investigated alpha6beta4 (beta4) and alphavbeta6 (beta6) integrin expressions in 48 ICCs, and evaluated their relationship with clinical and pathological parameters and ligand expression, as well as transforming growth factor (TGF)-beta1. beta4 and beta6 expressions were detected in 46 (96%) and 35 (73%) ICC cases, respectively. We classified ICC into negative, low (beta4, 29 cases; beta6, 36 cases), or high (beta4, 19 cases; beta6, 12 cases) integrin expression groups. beta4 and beta6 integrin levels were higher in the non-peripheral central localization type ICC than in the peripheral localization type; they were also higher in the periductal infiltrating or intraductal-growth types than in the mass-forming type ICC; lastly, they were higher in the well-differentiated type than in the poorly differentiated type ICC. High expression was related to bile duct invasion. In addition, beta4 and beta6 expressions were associated with mucin production and the expression of cytoplasmic epithelial membrane antigen, laminin-5, and tenascin-C. TGF-beta1 was correlated with beta6 expression and poor overall survival. These results suggest that integrin expression is associated with subclassification and clinicopathological features of ICC through the coincident expression of their ligands and TGF-beta1. PMID- 29584697 TI - Karyotype Evolution in Birds: From Conventional Staining to Chromosome Painting. AB - In the last few decades, there have been great efforts to reconstruct the phylogeny of Neoaves based mainly on DNA sequencing. Despite the importance of karyotype data in phylogenetic studies, especially with the advent of fluorescence in situ hybridization (FISH) techniques using different types of probes, the use of chromosomal data to clarify phylogenetic proposals is still minimal. Additionally, comparative chromosome painting in birds is restricted to a few orders, while in mammals, for example, virtually all orders have already been analyzed using this method. Most reports are based on comparisons using Gallus gallus probes, and only a small number of species have been analyzed with more informative sets of probes, such as those from Leucopternis albicollis and Gyps fulvus, which show ancestral macrochromosomes rearranged in alternative patterns. Despite this, it is appropriate to review the available cytogenetic information and possible phylogenetic conclusions. In this report, the authors gather both classical and molecular cytogenetic data and describe some interesting and unique characteristics of karyotype evolution in birds. PMID- 29584699 TI - Feasibility of Using Elastic Wave Velocity Monitoring for Early Warning of Rainfall-Induced Slope Failure. AB - Rainfall-induced landslides are one of the most widespread slope instability phenomena posing a serious risk to public safety worldwide so that their temporal prediction is of great interest to establish effective warning systems. The objective of this study is to determine the effectiveness of elastic wave velocities in the surface layer of the slope in monitoring, prediction and early warning of landslide. The small-scale fixed and varied, and large-scale slope model tests were conducted. Analysis of the results has established that the elastic wave velocity continuously decreases in response of moisture content and deformation and there was a distinct surge in the decrease rate of wave velocity when failure was initiated. Based on the preliminary results of this analysis, the method using the change in elastic wave velocity proves superior for landslide early warning and suggests that a warning be issued at switch of wave velocity decrease rate. PMID- 29584698 TI - Loss of One or Two PATZ1 Alleles Has a Critical Role in the Progression of Thyroid Carcinomas Induced by the RET/PTC1 Oncogene. AB - POZ/BTB and AT-hook-containing zinc finger protein 1 (PATZ1) is an emerging cancer-related gene that is downregulated in different human malignancies, including thyroid cancer, where its levels gradually decrease going from papillary thyroid carcinomas (PTC) to poorly differentiated and undifferentiated highly aggressive anaplastic carcinomas (ATC). The restoration of PATZ1 expression in thyroid cancer cells reverted their malignant phenotype by inducing mesenchymal-to-epithelial transition, thus validating a tumor suppressor role for PATZ1 and suggesting its involvement in thyroid cancer progression. Here, we investigated the consequences of the homozygous and heterozygous loss of PATZ1 in the context of a mouse modeling of PTC, represented by mice carrying the RET/PTC1 oncogene under the thyroid specific control of the thyroglobulin promoter RET/PTC1 (RET/PTC1TG). The phenotypic analysis of RET/PTC1TG mice intercrossed with Patz1-knockout mice revealed that deficiency of both Patz1 alleles enhanced thyroid cancer incidence in RET/PTC1TG mice, but not the heterozygous knockout of the Patz1 gene. However, both RET/PTC1TG;Patz1+/- and RET/PTC1TG;Patz1-/- mice developed a more aggressive thyroid cancer phenotype-characterized by higher Ki 67 expression, presence of ATCs, and increased incidence of solid variants of PTC than that shown by RET/PTC1TG; Patz1+/+ compound mice. These results confirm that PATZ1 downregulation has a critical role in thyroid carcinogenesis, showing that it cooperates with RET/PTC1 in thyroid cancer progression. PMID- 29584700 TI - Can Pulsed Electromagnetic Fields Trigger On-Demand Drug Release from High-Tm Magnetoliposomes? AB - Recently, magnetic nanoparticles (MNPs) have been used to trigger drug release from magnetoliposomes through a magneto-nanomechanical approach, where the mechanical actuation of the MNPs is used to enhance the membrane permeability. This result can be effectively achieved with low intensity non-thermal alternating magnetic field (AMF), which, however, found rare clinic application. Therefore, a different modality of generating non-thermal magnetic fields has now been investigated. Specifically, the ability of the intermittent signals generated by non-thermal pulsed electromagnetic fields (PEMFS) were used to verify if, once applied to high-transition temperature magnetoliposomes (high-Tm MLs), they could be able to efficiently trigger the release of a hydrophilic model drug. To this end, hydrophilic MNPs were combined with hydrogenated soybean phosphatidylcholine and cholesterol to design high-Tm MLs. The release of a dye was evaluated under the effect of PEMFs for different times. The MNPs motions produced by PEMF could effectively increase the bilayer permeability, without affecting the liposomes integrity and resulted in nearly 20% of release after 3 h exposure. Therefore, the current contribution provides an exciting proof-of concept for the ability of PEMFS to trigger drug release, considering that PEMFS find already application in therapy due to their anti-inflammatory effects. PMID- 29584701 TI - Optimizing Propagation of Staphylococcus aureus Infecting Bacteriophage vB_SauM phiIPLA-RODI on Staphylococcus xylosus Using Response Surface Methodology. AB - The use of bacteriophages for killing pathogenic bacteria is a feasible alternative to antibiotics and disinfectants. To obtain the large quantities of phages required for this application, large-scale production of bacteriophages must be optimized. This study aims to define conditions that maximize the phage yield of the virulent and polyvalent staphylococcal bacteriophage vB_SauM-phiIPLA RODI in broth culture, using the food-grade species Staphylococcus xylosus as the host strain to reduce the risk of growing massive quantities of pathogenic bacteria and therefore, to ensure the safety of the final phage stock. The effect of four variables, namely initial bacterial concentration (5.66-8.40 log10 colony forming unit (CFU)/mL), initial phage concentration (5-8 log10 plaque-forming unit (PFU)/mL), temperature (21-40 degrees C) and agitation (20-250 rpm), on phage yield (response) was studied by using response surface methodology (RSM). Successive experimental designs showed that agitation did not significantly impact phage yield, while temperature did have a significant effect, with 38 degrees C being the optimum for phage propagation. The results allowed the design of a model to describe phage yield as a function of the initial bacterial and phage concentrations at fixed agitation (135 rpm), and optimum temperature (38 degrees C). The maximum experimental phage yield obtained was 9.3 log10 PFU/mL, while that predicted by the model under the optimized conditions (7.07 log10 CFU/mL initial bacterial population and 6.00 log10 PFU/mL initial phage titer) was 9.25 +/- 0.30 log10 PFU/mL, with the desirability of 0.96. This yield is comparable to that obtained when the phage was propagated on the original host, Staphylococcus aureus. Bacteriophage phiIPLA-RODI showed the same host range and very similar biofilm removal ability regardless of the staphylococcal species used for its propagation. The results presented in this study show the suitability of using a food-grade strain of S. xylosus for the propagation of S. aureus infecting phages and the application of RSM to define the optimal propagation conditions. PMID- 29584703 TI - ABS-SmartComAgri: An Agent-Based Simulator of Smart Communication Protocols in Wireless Sensor Networks for Debugging in Precision Agriculture. AB - Smart communication protocols are becoming a key mechanism for improving communication performance in networks such as wireless sensor networks. However, the literature lacks mechanisms for simulating smart communication protocols in precision agriculture for decreasing production costs. In this context, the current work presents an agent-based simulator of smart communication protocols for efficiently managing pesticides. The simulator considers the needs of electric power, crop health, percentage of alive bugs and pesticide consumption. The current approach is illustrated with three different communication protocols respectively called (a) broadcast, (b) neighbor and (c) low-cost neighbor. The low-cost neighbor protocol obtained a statistically-significant reduction in the need of electric power over the neighbor protocol, with a very large difference according to the common interpretations about the Cohen's d effect size. The presented simulator is called ABS-SmartComAgri and is freely distributed as open source from a public research data repository. It ensures the reproducibility of experiments and allows other researchers to extend the current approach. PMID- 29584702 TI - Role of Macrophages in Brain Tumor Growth and Progression. AB - The role of macrophages in the growth and the progression of tumors has been extensively studied in recent years. A large body of data demonstrates that macrophage polarization plays an essential role in the growth and progression of brain tumors, such as gliomas, meningiomas, and medulloblastomas. The brain neoplasm cells have the ability to influence the polarization state of the tumor associated macrophages. In turn, innate immunity cells have a decisive role through regulation of the acquired immune response, but also through humoral cross-talking with cancer cells in the tumor microenvironment. Neoangiogenesis, which is an essential element in glial tumor progression, is even regulated by the tumor associated macrophages, whose activity is linked to other factors, such as hypoxia. In addition, macrophages play a decisive role in establishing the entry into the bloodstream of cancer cells. As is well known, the latter phenomenon is also present in brain tumors, even if they only rarely metastasize. Looking ahead in the future, we can imagine that characterizing the relationships between tumor and tumor associated macrophage, as well as the study of circulating tumor cells, could give us useful tools in prognostic evaluation and therapy. More generally, the study of innate immunity in brain tumors can boost the development of new forms of immunotherapy. PMID- 29584704 TI - Roles of Mitochondrial DNA Mutations in Stem Cell Ageing. AB - Mitochondrial DNA (mtDNA) mutations accumulate in somatic stem cells during ageing and cause mitochondrial dysfunction. In this review, we summarize the studies that link mtDNA mutations to stem cell ageing. We discuss the age-related behaviours of the somatic mtDNA mutations in stem cell populations and how they potentially contribute to stem cell ageing by altering mitochondrial properties in humans and in mtDNA-mutator mice. We also draw attention to the diverse fates of the mtDNA mutations with different origins during ageing, with potential selective pressures on the germline inherited but not the somatic mtDNA mutations. PMID- 29584705 TI - Particulate Guanylyl Cyclase A/cGMP Signaling Pathway in the Kidney: Physiologic and Therapeutic Indications. AB - The particulate guanylyl cyclase A (pGC-A)/cGMP pathway plays important roles in regulating renal physiological function and as well as in counteracting pathophysiological conditions. Naturally occurring peptide pGC-A activators consist of atrial natriuretic peptide (ANP), b-type NP (BNP), and urodilatin (URO). These activators bind and activate pGC-A, generating the second messenger cyclic 3',5' guanosine monophosphate (cGMP). Cyclic GMP binds to downstream pathway effector molecules including protein kinase G (PKG), cGMP-gated ion channels, and phosphodiesterases (PDEs). These mediators result in a variety of physiological actions in the kidney, including diuresis, natriuresis, increased glomerular filtration rate (GFR) and organ protection, thus, opposing renal cellular injury and remodeling. Downstream proteins regulated by PKG include collagen 1 (Col-1), transforming growth factor beta (TGF-beta) and apoptosis related proteins. In addition to their physiological regulatory effects, pGC A/cGMP signaling is critical for preserving renal homeostasis in different renal diseases such as acute kidney injury (AKI). Regarding therapeutic options, native pGC-A activators have short half-lives and their activity can be further enhanced by advances in innovative peptide engineering. Thus, novel designer peptide pGC-A activators with enhanced renal activity are under development. PMID- 29584706 TI - Tri-Trophic Impacts of Bt-Transgenic Maize on Parasitoid Size and Fluctuating Asymmetry in Native vs. Novel Host-Parasitoid Interactions in East Africa. AB - Environmental stress can affect trait size and cause an increase in the fluctuating asymmetry (FA) of bilateral morphological traits in many animals. For insect parasitoids, feeding of hosts on transgenic maize, expressing a Bacillus thuringiensis toxin gene is a potential environmental stressor. We compared the size of antennae, forewings, and tibia, as well as their FA values, in two parasitoids developed on two East African host species feeding on non-transgenic vs. transgenic maize. The two lepidopteran stem-borer hosts were the native Sesamia calamistis Hampson (Lepidoptera: Noctuidae) and a recent invader, Chilo partellus Swinhoe (Lepidoptera: Crambidae). The two braconid parasitoids were the native, gregarious larval endoparasitoid Cotesia sesamiae and the recently introduced Cotesia flavipes. Both parasitoids attacked both hosts, creating evolutionarily old vs. novel interactions. Transient feeding of hosts on transgenic maize had various effects on FA, depending on trait as well as the host and parasitoid species. These effects were usually stronger in evolutionarily novel host-parasitoid associations than in the older, native ones. These parameters have capacity to more sensitively indicate the effects of potential stressors and merit further consideration. PMID- 29584708 TI - Stereoselective Syntheses and Application of Chiral Bi- and Tridentate Ligands Derived from (+)-Sabinol. AB - A library of bidentate diols, as well as tridentate triols and aminodiols, derived from (+)-sabinol, was synthesized in a stereoselective manner. Sabinol was transformed into allylic trichloroacetamide via Overman rearrangement of the corresponding trichloroacetimidate. After changing the protecting group to Boc, the enamine was subjected to stereospecific dihydroxylation with OsO4/NMO, resulting in the (1R,2R,3R,5R)-aminodiol diastereomer. The obtained primary aminodiol was transformed to a secondary analogue. The ring closure of the N benzyl-substituted aminodiol with formaldehyde was investigated and regioselective formation of the spiro-oxazolidine ring was observed. Hydroboration or dihydroxylation of sabinol or its benzyl ether with OsO4/NMO resulted in the formation of sabinane-based diols and triols following a highly stereospecific reaction. Treatment of sabinol with m-CPBA afforded O-benzoyl triol as a diastereoisomer of the directly dihydroxylated product, instead of the expected epoxy alcohol. The resulting aminodiols, diol, and triols were applied as chiral catalysts in the reaction of diethylzinc and benzaldehyde from moderate to good selectivity. PMID- 29584707 TI - MDM2-p53 Interactions in Human Hepatocellular Carcinoma: What Is the Role of Nutlins and New Therapeutic Options? AB - Human hepatocellular carcinoma (HCC) is the fifth most common cancer and is associated with poor prognosis worldwide. The molecular mechanisms underlying the pathogenesis of HCC have been an area of continuing interest, and recent studies using next generation sequencing (NGS) have revealed much regarding previously unsettled issues. Molecular studies using HCC samples have been mainly targeted with the aim to identify the fundamental mechanisms contributing to HCC and identify more effective treatments. In response to cellular stresses (e.g., DNA damage or oncogenes), activated p53 elicits appropriate responses that aim at DNA repair, genetic stability, cell cycle arrest, and the deletion of DNA-damaged cells. On the other hand, the murine double minute 2 (MDM2) oncogene protein is an important cellular antagonist of p53. MDM2 negatively regulates p53 activity through the induction of p53 protein degradation. However, current research has shown that the mechanisms underlying MDM2-p53 interactions are more complex than previously thought. Microarray data have added new insight into the transcription changes in HCC. Recently, Nutlin-3 has shown potency against p53-MDM2 binding and the enhancement of p53 stabilization as well as an increment of p53 cellular accumulation with potential therapeutic effects. This review outlines the molecular mechanisms involved in the p53-MDM2 pathways, the biological factors influencing these pathways, and their roles in the pathogenesis of HCC. It also discusses the action of Nutlin-3 treatment in inducing growth arrest in HCC and elaborates on future directions in research in this area. More research on the biology of p53-MDM2 interactions may offer a better understanding of these mechanisms and discover new biomarkers, sensitive prognostic indicators as well as new therapeutic interventions in HCC. PMID- 29584709 TI - In Silico Discovery of a Substituted 6-Methoxy-quinalidine with Leishmanicidal Activity in Leishmania infantum. AB - There is an urgent need for the discovery of new antileishmanial drugs with a new mechanism of action. Type 2 NADH dehydrogenase from Leishmania infantum (LiNDH2) is an enzyme of the parasite's respiratory system, which catalyzes the electron transfer from NADH to ubiquinone without coupled proton pumping. In previous studies of the related NADH: ubiquinone oxidoreductase crystal structure from Saccharomyces cerevisiae, two ubiquinone-binding sites (UQI and UQII) were identified and shown to play an important role in the NDH-2-catalyzed oxidoreduction reaction. Based on the available structural data, we developed a three-dimensional structural model of LiNDH2 using homology detection methods and performed an in silico virtual screening campaign to search for potential inhibitors targeting the LiNDH2 ubiquinone-binding site 1-UQI. Selected compounds displaying favorable properties in the computational screening experiments were assayed for inhibitory activity in the structurally similar recombinant NDH-2 from S. aureus and leishmanicidal activity was determined in the wild-type axenic amastigotes and promastigotes of L. infantum. The identified compound, a substituted 6-methoxy-quinalidine, showed promising nanomolar leishmanicidal activity on wild-type axenic promastigotes and amastigotes of L. infantum and the potential for further development. PMID- 29584710 TI - Mobility Enhancement in Amorphous In-Ga-Zn-O Thin-Film Transistor by Induced Metallic in Nanoparticles and Cu Electrodes. AB - In this work, we fabricated a high-mobility amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistor (TFT) based on alumina oxide (Al 2 O 3 ) passivation layer (PVL) and copper (Cu) source/drain electrodes (S/D). The mechanism of the high mobility for a-IGZO TFT was proposed and experimentally demonstrated. The conductivity of the channel layer was significantly improved due to the formation of metallic In nanoparticles on the back channel during Al 2 O 3 PVL sputtering. In addition, Ar atmosphere annealing induced the Schottky contact formation between the Cu S/D and the channel layer caused by Cu diffusion. In conjunction with high conductivity channel and Schottky contact, the a-IGZO TFT based on Cu S/D and Al 2 O 3 PVL exhibited remarkable mobility of 33.5-220.1 cm 2 /Vs when channel length varies from 60 to 560 MU m. This work presents a feasible way to implement high mobility and Cu electrodes in a-IGZO TFT, simultaneously. PMID- 29584712 TI - Early career investigator highlight-June. PMID- 29584711 TI - Proteomics Analysis to Assess the Role of Mitochondria in BRCA1-Mediated Breast Tumorigenesis. AB - Mitochondria are the organelles deputed to energy production, but they are also involved in carcinogenesis, cancer progression, and metastasis, playing a role in altered energy metabolism in cancer cells. Mitochondrial metabolism is connected with several mitochondrial pathways such as ROS signaling, Ca2+ homeostasis, mitophagy, and mitochondrial biogenesis. These pathways are merged in an interactive super-network that seems to play a crucial role in cancer. Germline mutations of the BRCA1 gene account for 5-10% of breast cancers and confer a risk of developing the disease 10- to 20-fold much higher than in non-carriers. By considering metabolic networks that could reconcile both genetic and non-genetic causal mechanisms in BRCA1 driven tumorigenesis, we herein based our study on the hypothesis that BRCA1 haploinsufficiency might drive metabolic rewiring in breast epithelial cells, acting as a push toward malignant transformation. Using 2D-DIGE we analyzed and compared the mitochondrial proteomic profile of sporadic breast cancer cell line (MCF7) and BRCA1 mutated breast cancer cell line (HCC1937). Image analysis was carried out with Decider Software, and proteins differentially expressed were identified by LC-MS/MS on a quadrupole-orbitrap mass spectrometer Q-Exactive. Ingenuity pathways analysis software was used to analyze the fifty three mitochondrial proteins whose expression resulted significantly altered in response to BRCA1 mutation status. Mitochondrial Dysfunction and oxidative phosphorylation, and energy production and nucleic acid metabolism were, respectively, the canonical pathway and the molecular function mainly affected. Western blotting analysis was done to validate the expression and the peculiar mitochondrial compartmentalization of specific proteins such us HSP60 and HIF 1alpha. Particularly intriguing is the correlation between BRCA1 mutation status and HIF-1alpha localization into the mitochondria in a BRCA1 dependent manner. Data obtained led us to hypothesize an interesting connection between BRCA1 and mitochondria pathways, capable to trigger metabolic changes, which, in turn, sustain the high energetic and anabolic requirements of the malignant phenotype.

AB - BackgroundPelizaeus Merzbacher disease (PMD) is a dysmyelinating disorder of the central nervous system caused by impaired differentiation of oligodendrocytes. This study was prompted by findings that antimuscarinic compounds enhance oligodendrocyte differentiation and remyelination in vitro. One of these compounds, clemastine fumarate, is licensed for treatment of allergic conditions. We tested whether clemastine fumarate can promote myelination in two rodent PMD models, the myelin-deficient and the PLP transgenic rat.MethodsPups were treated with daily injections of clemastine (10-30 mg/kg/day) on postnatal days 1-21. Neurologic phenotypes and myelination patterns in the brain, optic nerves, and spinal cords were assessed using histological techniques.ResultsNo changes in neurological phenotype or survival were observed even at the highest dose of clemastine. Postmortem staining with Luxol fast blue and myelin basic protein immunohistochemistry revealed no evidence for improved myelination in the CNS of treated rats compared to vehicle-treated littermates. Populations of mature oligodendrocytes were unaffected by the treatment.ConclusionThese results demonstrate lack of therapeutic effect of clemastine in two rat PMD models. Both models have rapid disease progression consistent with the connatal form of the disease. Further studies are necessary to determine whether clemastine bears a therapeutic potential in milder forms of PMD.

AB - In a Persepctive, Richard Fluck and Maarten Taal discuss the potential value of implementing multidisciplinary care programs for chronic kidney disease. PMID- 29584716 TI - Evaluation of e-liquid toxicity using an open-source high-throughput screening assay. AB - The e-liquids used in electronic cigarettes (E-cigs) consist of propylene glycol (PG), vegetable glycerin (VG), nicotine, and chemical additives for flavoring. There are currently over 7,700 e-liquid flavors available, and while some have been tested for toxicity in the laboratory, most have not. Here, we developed a 3 phase, 384-well, plate-based, high-throughput screening (HTS) assay to rapidly triage and validate the toxicity of multiple e-liquids. Our data demonstrated that the PG/VG vehicle adversely affected cell viability and that a large number of e-liquids were more toxic than PG/VG. We also performed gas chromatography mass spectrometry (GC-MS) analysis on all tested e-liquids. Subsequent nonmetric multidimensional scaling (NMDS) analysis revealed that e-liquids are an extremely heterogeneous group. Furthermore, these data indicated that (i) the more chemicals contained in an e-liquid, the more toxic it was likely to be and (ii) the presence of vanillin was associated with higher toxicity values. Further analysis of common constituents by electron ionization revealed that the concentration of cinnamaldehyde and vanillin, but not triacetin, correlated with toxicity. We have also developed a publicly available searchable website (www.eliquidinfo.org). Given the large numbers of available e-liquids, this website will serve as a resource to facilitate dissemination of this information. Our data suggest that an HTS approach to evaluate the toxicity of multiple e liquids is feasible. Such an approach may serve as a roadmap to enable bodies such as the Food and Drug Administration (FDA) to better regulate e-liquid composition. PMID- 29584717 TI - Dynamic combination of sensory and reward information under time pressure. AB - When making choices, collecting more information is beneficial but comes at the cost of sacrificing time that could be allocated to making other potentially rewarding decisions. To investigate how the brain balances these costs and benefits, we conducted a series of novel experiments in humans and simulated various computational models. Under six levels of time pressure, subjects made decisions either by integrating sensory information over time or by dynamically combining sensory and reward information over time. We found that during sensory integration, time pressure reduced performance as the deadline approached, and choice was more strongly influenced by the most recent sensory evidence. By fitting performance and reaction time with various models we found that our experimental results are more compatible with leaky integration of sensory information with an urgency signal or a decision process based on stochastic transitions between discrete states modulated by an urgency signal. When combining sensory and reward information, subjects spent less time on integration than optimally prescribed when reward decreased slowly over time, and the most recent evidence did not have the maximal influence on choice. The suboptimal pattern of reaction time was partially mitigated in an equivalent control experiment in which sensory integration over time was not required, indicating that the suboptimal response time was influenced by the perception of imperfect sensory integration. Meanwhile, during combination of sensory and reward information, performance did not drop as the deadline approached, and response time was not different between correct and incorrect trials. These results indicate a decision process different from what is involved in the integration of sensory information over time. Together, our results not only reveal limitations in sensory integration over time but also illustrate how these limitations influence dynamic combination of sensory and reward information. PMID- 29584718 TI - Rapid evolution of a voltage-gated sodium channel gene in a lineage of electric fish leads to a persistent sodium current. AB - Most weakly electric fish navigate and communicate by sensing electric signals generated by their muscle-derived electric organs. Adults of one lineage (Apteronotidae), which discharge their electric organs in excess of 1 kHz, instead have an electric organ derived from the axons of specialized spinal neurons (electromotorneurons [EMNs]). EMNs fire spontaneously and are the fastest firing neurons known. This biophysically extreme phenotype depends upon a persistent sodium current, the molecular underpinnings of which remain unknown. We show that a skeletal muscle-specific sodium channel gene duplicated in this lineage and, within approximately 2 million years, began expressing in the spinal cord, a novel site of expression for this isoform. Concurrently, amino acid replacements that cause a persistent sodium current accumulated in the regions of the channel underlying inactivation. Therefore, a novel adaptation allowing extreme neuronal firing arose from the duplication, change in expression, and rapid sequence evolution of a muscle-expressing sodium channel gene. PMID- 29584719 TI - Dynamic cues for whisker-based object localization: An analytical solution to vibration during active whisker touch. AB - Vibrations are important cues for tactile perception across species. Whisker based sensation in mice is a powerful model system for investigating mechanisms of tactile perception. However, the role vibration plays in whisker-based sensation remains unsettled, in part due to difficulties in modeling the vibration of whiskers. Here, we develop an analytical approach to calculate the vibrations of whiskers striking objects. We use this approach to quantify vibration forces during active whisker touch at a range of locations along the whisker. The frequency and amplitude of vibrations evoked by contact are strongly dependent on the position of contact along the whisker. The magnitude of vibrational shear force and bending moment is comparable to quasi-static forces. The fundamental vibration frequencies are in a detectable range for mechanoreceptor properties and below the maximum spike rates of primary sensory afferents. These results suggest two dynamic cues exist that rodents can use for object localization: vibration frequency and comparison of vibrational to quasi static force magnitude. These complement the use of quasi-static force angle as a distance cue, particularly for touches close to the follicle, where whiskers are stiff and force angles hardly change during touch. Our approach also provides a general solution to calculation of whisker vibrations in other sensing tasks. PMID- 29584720 TI - Cost-effectiveness of multidisciplinary care in mild to moderate chronic kidney disease in the United States: A modeling study. AB - BACKGROUND: Multidisciplinary care (MDC) programs have been proposed as a way to alleviate the cost and morbidity associated with chronic kidney disease (CKD) in the US. METHODS AND FINDINGS: We assessed the cost-effectiveness of a theoretical Medicare-based MDC program for CKD compared to usual CKD care in Medicare beneficiaries with stage 3 and 4 CKD between 45 and 84 years old in the US. The program used nephrologists, advanced practitioners, educators, dieticians, and social workers. From Medicare claims and published literature, we developed a novel deterministic Markov model for CKD progression and calibrated it to long term risks of mortality and progression to end-stage renal disease. We then used the model to project accrued discounted costs and quality-adjusted life years (QALYs) over patients' remaining lifetime. We estimated the incremental cost effectiveness ratio (ICER) of MDC, or the cost of the intervention per QALY gained. MDC added 0.23 (95% CI: 0.08, 0.42) QALYs over usual care, costing $51,285 per QALY gained (net monetary benefit of $23,100 at a threshold of $150,000 per QALY gained; 95% CI: $6,252, $44,323). In all subpopulations analyzed, ICERs ranged from $42,663 to $72,432 per QALY gained. MDC was generally more cost-effective in patients with higher urine albumin excretion. Although ICERs were higher in younger patients, MDC could yield greater improvements in health in younger than older patients. MDC remained cost-effective when we decreased its effectiveness to 25% of the base case or increased the cost 5-fold. The program costed less than $70,000 per QALY in 95% of probabilistic sensitivity analyses and less than $87,500 per QALY in 99% of analyses. Limitations of our study include its theoretical nature and being less generalizable to populations at low risk for progression to ESRD. We did not study the potential impact of MDC on hospitalization (cardiovascular or other). CONCLUSIONS: Our model estimates that a Medicare-funded MDC program could reduce the need for dialysis, prolong life expectancy, and meet conventional cost-effectiveness thresholds in middle aged to elderly patients with mild to moderate CKD. PMID- 29584721 TI - Multimorbidity in patients with heart failure from 11 Asian regions: A prospective cohort study using the ASIAN-HF registry. AB - BACKGROUND: Comorbidities are common in patients with heart failure (HF) and complicate treatment and outcomes. We identified patterns of multimorbidity in Asian patients with HF and their association with patients' quality of life (QoL) and health outcomes. METHODS AND FINDINGS: We used data on 6,480 patients with chronic HF (1,204 with preserved ejection fraction) enrolled between 1 October 2012 and 6 October 2016 in the Asian Sudden Cardiac Death in Heart Failure (ASIAN HF) registry. The ASIAN-HF registry is a prospective cohort study, with patients prospectively enrolled from in- and outpatient clinics from 11 Asian regions (Hong Kong, Taiwan, China, Japan, Korea, India, Malaysia, Thailand, Singapore, Indonesia, and Philippines). Latent class analysis was used to identify patterns of multimorbidity. The primary outcome was defined as a composite of all-cause mortality or HF hospitalization within 1 year. To assess differences in QoL, we used the Kansas City Cardiomyopathy Questionnaire. We identified 5 distinct multimorbidity groups: elderly/atrial fibrillation (AF) (N = 1,048; oldest, more AF), metabolic (N = 1,129; obesity, diabetes, hypertension), young (N = 1,759; youngest, low comorbidity rates, non-ischemic etiology), ischemic (N = 1,261; ischemic etiology), and lean diabetic (N = 1,283; diabetic, hypertensive, low prevalence of obesity, high prevalence of chronic kidney disease). Patients in the lean diabetic group had the worst QoL, more severe signs and symptoms of HF, and the highest rate of the primary combined outcome within 1 year (29% versus 11% in the young group) (p for all <0.001). Adjusting for confounders (demographics, New York Heart Association class, and medication) the lean diabetic (hazard ratio [HR] 1.79, 95% CI 1.46-2.22), elderly/AF (HR 1.57, 95% CI 1.26-1.96), ischemic (HR 1.51, 95% CI 1.22-1.88), and metabolic (HR 1.28, 95% CI 1.02-1.60) groups had higher rates of the primary combined outcome compared to the young group. Potential limitations include site selection and participation bias. CONCLUSIONS: Among Asian patients with HF, comorbidities naturally clustered in 5 distinct patterns, each differentially impacting patients' QoL and health outcomes. These data underscore the importance of studying multimorbidity in HF and the need for more comprehensive approaches in phenotyping patients with HF and multimorbidity. TRIAL REGISTRATION: ClinicalTrials.gov NCT01633398. PMID- 29584722 TI - PIKfyve regulates melanosome biogenesis. AB - PIKfyve, VAC14, and FIG4 form a complex that catalyzes the production of PI(3,5)P2, a signaling lipid implicated in process ranging from lysosome maturation to neurodegeneration. While previous studies have identified VAC14 and FIG4 mutations that lead to both neurodegeneration and coat color defects, how PIKfyve regulates melanogenesis is unknown. In this study, we sought to better understand the role of PIKfyve in melanosome biogenesis. Melanocyte-specific PIKfyve knockout mice exhibit greying of the mouse coat and the accumulation of single membrane vesicle structures in melanocytes resembling multivesicular endosomes. PIKfyve inhibition blocks melanosome maturation, the processing of the melanosome protein PMEL, and the trafficking of the melanosome protein TYRP1. Taken together, these studies identify a novel role for PIKfyve in controlling the delivery of proteins from the endosomal compartment to the melanosome, a role that is distinct from the role of PIKfyve in the reformation of lysosomes from endolysosomes. PMID- 29584723 TI - Transmission of HIV-1 drug resistance mutations within partner-pairs: A cross sectional study of a primary HIV infection cohort. AB - BACKGROUND: Transmission of human immunodeficiency virus type 1 (HIV-1) drug resistance mutations, particularly that of minority drug-resistant variants, remains poorly understood. Population-based studies suggest that drug-resistant HIV-1 is less transmissible than drug-susceptible viruses. We compared HIV-1 drug resistant genotypes among partner-pairs in order to assess the likelihood of transmission of drug resistance mutations and investigate the role of minority variants in HIV transmission. METHODS AND FINDINGS: From 1992-2010, 340 persons with primary HIV-1 infection and their partners were enrolled into observational research studies at the University of Washington Primary Infection Clinic (UWPIC). Out of 50 partner-pairs enrolled, 36 (72%) transmission relationships were confirmed by phylogenetic distance analysis of HIV-1 envelope (env) sequences, and 31 partner-pairs enrolled after 1995 met criteria for this study. Drug resistance mutations in the region of the HIV-1 polymerase gene (pol) that encodes protease and reverse transcriptase were assessed by 454-pyrosequencing. In 25 partner-pairs where the transmission direction could be determined, 12 (48%) transmitters had 1-4 drug resistance mutations (23 total) detected in their HIV-1 populations at a median frequency of 6.0% (IQR 1.5%-98.7%, range 1.0% 99.6%). Of 10 major mutations detected in five transmitters at a frequency >95%, 100% (95% CI 69.2%-100%) were detected in recipients. All of these transmitters were antiretroviral (ARV)-naive at the time of specimen collection. Fourteen mutations (eight major mutations and six accessory mutations) were detected in nine transmitters at low frequencies (1.0%-11.8%); four of these transmitters had previously received ARV therapy. Two (14% [95% CI 1.8%-42.8%]) G73S accessory mutations were detected in both transmitter and recipient. This number is not significantly different from the number expected based on the observed frequencies of drug-resistant viruses in transmitting partners. Limitations of this study include the small sample size and uncertainties in determining the timing of virus transmission and mutation history. CONCLUSIONS: Drug-resistant majority variants appeared to be commonly transmitted by ARV-naive participants in our analysis and may contribute significantly to transmitted drug resistance on a population level. When present at low frequency, no major mutation was observed to be shared between partner-pairs; identification of accessory mutations shared within a pair could be due to transmission, laboratory artifact, or apolipoprotein B mRNA-editing enzyme, catalytic polypeptides (APOBECs), and warrants further study. PMID- 29584724 TI - Developing a Buruli ulcer community of practice in Bankim, Cameroon: A model for Buruli ulcer outreach in Africa. AB - BACKGROUND: In the Cameroon, previous efforts to identify Buruli ulcer (BU) through the mobilization of community health workers (CHWs) yielded poor results. In this paper, we describe the successful creation of a BU community of practice (BUCOP) in Bankim, Cameroon composed of hospital staff, former patients, CHWs, and traditional healers. METHODS AND PRINCIPLE FINDINGS: All seven stages of a well-defined formative research process were conducted during three phases of research carried out by a team of social scientists working closely with Bankim hospital staff. Phase one ethnographic research generated interventions tested in a phase two proof of concept study followed by a three- year pilot project. In phase three the pilot project was evaluated. An outcome evaluation documented a significant rise in BU detection, especially category I cases, and a shift in case referral. Trained CHW and traditional healers initially referred most suspected cases of BU to Bankim hospital. Over time, household members exposed to an innovative and culturally sensitive outreach education program referred the greatest number of suspected cases. Laboratory confirmation of suspected BU cases referred by community stakeholders was above 30%. An impact and process evaluation found that sustained collaboration between health staff, CHWs, and traditional healers had been achieved. CHWs came to play a more active role in organizing BU outreach activities, which increased their social status. Traditional healers found they gained more from collaboration than they lost from referral. CONCLUSION/ SIGNIFICANCE: Setting up lines of communication, and promoting collaboration and trust between community stakeholders and health staff is essential to the control of neglected tropical diseases. It is also essential to health system strengthening and emerging disease preparedness. The BUCOP model described in this paper holds great promise for bringing communities together to solve pressing health problems in a culturally sensitive manner. PMID- 29584726 TI - Comparative analysis of the association between 35 frailty scores and cardiovascular events, cancer, and total mortality in an elderly general population in England: An observational study. AB - BACKGROUND: Frail elderly people experience elevated mortality. However, no consensus exists on the definition of frailty, and many frailty scores have been developed. The main aim of this study was to compare the association between 35 frailty scores and incident cardiovascular disease (CVD), incident cancer, and all-cause mortality. Also, we aimed to assess whether frailty scores added predictive value to basic and adjusted models for these outcomes. METHODS AND FINDINGS: Through a structured literature search, we identified 35 frailty scores that could be calculated at wave 2 of the English Longitudinal Study of Ageing (ELSA), an observational cohort study. We analysed data from 5,294 participants, 44.9% men, aged 60 years and over. We studied the association between each of the scores and the incidence of CVD, cancer, and all-cause mortality during a 7-year follow-up using Cox proportional hazard models at progressive levels of adjustment. We also examined the added predictive performance of each score on top of basic models using Harrell's C statistic. Using age of the participant as a timescale, in sex-adjusted models, hazard ratios (HRs) (95% confidence intervals) for all-cause mortality ranged from 2.4 (95% CI: 1.7-3.3) to 26.2 (95% CI: 15.4-44.5). In further adjusted models including smoking status and alcohol consumption, HR ranged from 2.3 (95% CI: 1.6-3.1) to 20.2 (95% CI: 11.8-34.5). In fully adjusted models including lifestyle and comorbidity, HR ranged from 0.9 (95% CI: 0.5-1.7) to 8.4 (95% CI: 4.9-14.4). HRs for CVD and cancer incidence in sex-adjusted models ranged from 1.2 (95% CI: 0.5-3.2) to 16.5 (95% CI: 7.8-35.0) and from 0.7 (95% CI: 0.4-1.2) to 2.4 (95% CI: 1.0-5.7), respectively. In sex- and age-adjusted models, all frailty scores showed significant added predictive performance for all-cause mortality, increasing the C statistic by up to 3%. None of the scores significantly improved basic prediction models for CVD or cancer. A source of bias could be the differences in mortality follow-up time compared to CVD/cancer, because the existence of informative censoring cannot be excluded. CONCLUSION: There is high variability in the strength of the association between frailty scores and 7-year all-cause mortality, incident CVD, and cancer. With regard to all-cause mortality, some scores give a modest improvement to the predictive ability. Our results show that certain scores clearly outperform others with regard to three important health outcomes in later life. Finally, we think that despite their limitations, the use of frailty scores to identify the elderly population at risk is still a useful measure, and the choice of a frailty score should balance feasibility with performance. PMID- 29584725 TI - Prevalence of metabolic syndrome and its risk factors in Kerala, South India: Analysis of a community based cross-sectional study. AB - BACKGROUND: Coronary Artery Disease (CAD) is a leading cause of death and disability in Kerala, India. Metabolic syndrome (MS) is a constellation of established risk factors for CAD. We aimed to estimate the prevalence of MS and evaluate the association between MS and CAD using a community-based sample population. METHODS: A cross-sectional community based survey was conducted in urban and rural areas of Kerala in 2011. We included 5063 individuals for analysis. Age standardized prevalence of MS, associated diagnoses (hypertension, diabetes and hypercholesterolemia) and other potential risk factors were assessed for men and women in both urban and rural locations. Univariate and multivariate logistic regression models were developed to identify participant characteristics that are associated with MS. RESULTS: After standardization for age and adjustment for sex and urban-rural distribution, the prevalence of metabolic syndrome in Kerala was 24%, 29% and 33% for the NCEP ATP III, IDF and AHA/NHLBI Harmonization definitions, respectively. The mean (SD) age of the participants was 51 (14) years, and 60% were women. Women had a higher prevalence of MS than men (28% versus 20% for ATP III, p<0.001). Similarly, participants living in urban areas had higher prevalence of MS than their rural counterparts (26% versus 22%, p<0.001). Elevated body mass index, older age, and female sex were associated with MS in an adjusted multivariate model. The propensity for definite CAD was 1.7 times higher in individuals with MS defined based on ATP III criteria compared to those without MS (Adjusted OR = 1.69; 95% CI: 1.3-2.2, p<0.001). CONCLUSIONS: One of four to one of three adult individuals in Kerala have MS based on different criteria. Higher propensity for CAD in individuals with MS in Kerala calls for urgent steps to prevent and control the burden of metabolic conditions. PMID- 29584727 TI - Determinants of delay in timely treatment seeking for diarrheal diseases among mothers with under-five children in central Ethiopia: A case control study. AB - BACKGROUND: Delays in seeking timely appropriate care contributes to a large number of deaths from diarrhea in children. This study aimed to identify determinants of delays in seeking timely treatment by mothers/caregivers of under five children with diarrheal diseases. METHODS: We used an unmatched case-control study from February-March 2017 among 316 children: 158 cases and 158 controls. Cases were mothers/caregivers with under-five children who had signs/symptoms of diarrhea and sought treatment after 24 hours onset of symptom. Controls sought treatment within 24 hours. Field workers collected data using a pre-tested standardized questionnaire. Multivariate logistic regression was conducted to identify determinants of delay in timely diarrhea treatment seeking. Statistical significance was declared by using a p-value<0.05 and 95% of confidence interval (CI) for an adjusted-odds ratio (AOR). RESULTS: The determinants of delay in timely treatment seeking of mothers/caregivers of under-five children with diarrheal diseases were children <24months (AOR = 1.9,95%CI:1.1-3.4); fail to attend school (AOR = 2.4, 95%CI:1.2-4.6); being female children (AOR = 1.7,95%CI:1.05-2.9); preferring government health facility for the treatment of children with diarrheal diseases (AOR = 2.9, 95%CI, 1.3-6.7); lack of past history taking children to health facility and lack of counseling (AOR = 4.8, 95%CI:2.0-12.1); being in the15-25 years age (AOR = 1.7, 95%CI:1.1-3.0) and taking children to a health facility as a first response to diarrhea (AOR = 0.1, 95%CI:0.01-0.8). CONCLUSIONS: Age of the child, maternal age, and disease related determinants were determinants for seeking timely treatment to diarrheal diseases. Providing skilled based health education and counseling to mothers/caregivers on seeking timely treatment and taking children with diarrheal diseases to a health facility as a first response to diarrhea is a paramount intervention to reduce morbidity and mortality of children. PMID- 29584728 TI - Bifurcation analysis of two coupled Jansen-Rit neural mass models. AB - We investigate how changes in network structure can lead to pathological oscillations similar to those observed in epileptic brain. Specifically, we conduct a bifurcation analysis of a network of two Jansen-Rit neural mass models, representing two cortical regions, to investigate different aspects of its behavior with respect to changes in the input and interconnection gains. The bifurcation diagrams, along with simulated EEG time series, exhibit diverse behaviors when varying the input, coupling strength, and network structure. We show that this simple network of neural mass models can generate various oscillatory activities, including delta wave activity, which has not been previously reported through analysis of a single Jansen-Rit neural mass model. Our analysis shows that spike-wave discharges can occur in a cortical region as a result of input changes in the other region, which may have important implications for epilepsy treatment. The bifurcation analysis is related to clinical data in two case studies. PMID- 29584729 TI - Exact and heuristic algorithms for Space Information Flow. AB - Space Information Flow (SIF) is a new promising research area that studies network coding in geometric space, such as Euclidean space. The design of algorithms that compute the optimal SIF solutions remains one of the key open problems in SIF. This work proposes the first exact SIF algorithm and a heuristic SIF algorithm that compute min-cost multicast network coding for N (N >= 3) given terminal nodes in 2-D Euclidean space. Furthermore, we find that the Butterfly network in Euclidean space is the second example besides the Pentagram network where SIF is strictly better than Euclidean Steiner minimal tree. The exact algorithm design is based on two key techniques: Delaunay triangulation and linear programming. Delaunay triangulation technique helps to find practically good candidate relay nodes, after which a min-cost multicast linear programming model is solved over the terminal nodes and the candidate relay nodes, to compute the optimal multicast network topology, including the optimal relay nodes selected by linear programming from all the candidate relay nodes and the flow rates on the connection links. The heuristic algorithm design is also based on Delaunay triangulation and linear programming techniques. The exact algorithm can achieve the optimal SIF solution with an exponential computational complexity, while the heuristic algorithm can achieve the sub-optimal SIF solution with a polynomial computational complexity. We prove the correctness of the exact SIF algorithm. The simulation results show the effectiveness of the heuristic SIF algorithm.

PMID- 29584730 TI - Antiviral efficacy of favipiravir against Ebola virus: A translational study in cynomolgus macaques. AB - BACKGROUND: Despite repeated outbreaks, in particular the devastating 2014-2016 epidemic, there is no effective treatment validated for patients with Ebola virus disease (EVD). Among the drug candidates is the broad-spectrum polymerase inhibitor favipiravir, which showed a good tolerance profile in patients with EVD (JIKI trial) but did not demonstrate a strong antiviral efficacy. In order to gain new insights into the antiviral efficacy of favipiravir and improve preparedness and public health management of future outbreaks, we assess the efficacy achieved by ascending doses of favipiravir in Ebola-virus-infected nonhuman primates (NHPs). METHODS AND FINDINGS: A total of 26 animals (Macaca fascicularis) were challenged intramuscularly at day 0 with 1,000 focus-forming units of Ebola virus Gabon 2001 strain and followed for 21 days (study termination). This included 13 animals left untreated and 13 treated with doses of 100, 150, and 180 mg/kg (N = 3, 5, and 5, respectively) favipiravir administered intravenously twice a day for 14 days, starting 2 days before infection. All animals left untreated or treated with 100 mg/kg died within 10 days post-infection, while animals receiving 150 and 180 mg/kg had extended survival (P < 0.001 and 0.001, respectively, compared to untreated animals), leading to a survival rate of 40% (2/5) and 60% (3/5), respectively, at day 21. Favipiravir inhibited viral replication (molecular and infectious viral loads) in a drug-concentration-dependent manner (P values < 0.001), and genomic deep sequencing analyses showed an increase in virus mutagenesis over time. These results allowed us to identify that plasma trough favipiravir concentrations greater than 70-80 MUg/ml were associated with reduced viral loads, lower virus infectivity, and extended survival. These levels are higher than those found in the JIKI trial, where patients had median trough drug concentrations equal to 46 and 26 MUg/ml at day 2 and day 4 post-treatment, respectively, and suggest that the dosing regimen in the JIKI trial was suboptimal. The environment of a biosafety level 4 laboratory introduces a number of limitations, in particular the difficulty of conducting blind studies and performing detailed pharmacological assessments. Further, the extrapolation of the results to patients with EVD is limited by the fact that the model is fully lethal and that treatment initiation in patients with EVD is most often initiated several days after infection, when symptoms and high levels of viral replication are already present. CONCLUSIONS: Our results suggest that favipiravir may be an effective antiviral drug against Ebola virus that relies on RNA chain termination and possibly error catastrophe. These results, together with previous data collected on tolerance and pharmacokinetics in both NHPs and humans, support a potential role for high doses of favipiravir for future human interventions. PMID- 29584732 TI - Wood-boring beetles associated with Acacia xanthophloea in Nairobi and Machakos Counties, Kenya. AB - Naivasha thorn tree, Acacia xanthophloea, is grown for foliage, timber, shade and rehabilitation of soils in areas with high water tables in Kenya. Its production is threatened by insect pests, which cause major losses. Very little is documented on wood-boring beetles which cause considerable economic damage to lumber used in a variety of applications, and little is known about their natural enemies in Kenya. We conducted the study to evaluate the occurrence of wood boring beetles on A. xanthophloea in two different regions of Kenya. Infested wood samples of A. xanthophloea with fresh exit holes were collected from three sites in Kenyatta University (KU), Nairobi and Mitaboni in Machakos, Kenya. The samples were placed in clear plastic buckets and kept at ambient temperatures 23+/-2 degrees C, 65+/-10% relative humidity and 12L: 12D in a laboratory where they were observed daily for adult emergence. Adult beetles were collected every three days for identification and data recording. The experiment was replicated four times and data collected twice a week for 6 months. Data on abundance was subjected to analysis of variance using SAS software. A total of 5,850 and 4,691 beetles were collected where 2,187 and 3,097 were Bostrichidae, accounting for 37% and 66% in KU and Mitaboni, respectively. A total of 12 bostrichid species was identified, including Sinoxylon ruficorne, S. doliolum, Xylion adustus, Xyloperthodes nitidipennis, Xyloperthella picea, Xylopsocus castanoptera, Lyctus brunneus, Heterbostrychus brunneus, Xylopsocus sp., and Dinoderus gabonicus. The most abundant species in KU was Xylion adustus with 1,915 beetles accounting for 88.4%, and Sinoxylon ruficorne in Mitaboni with 1,050 beetles accounting for 33.9% of the total. Sinoxylon ruficorne was only recorded in Mitaboni while only 2 specimens of D. gabonicus were found in KU. The mean number of exit holes on A. xanthophloea differed significantly between sites, which corresponded approximately to the amount of economic damage caused by the beetles to the structural integrity of the lumber. In addition, a number of predators in the family Cerambycidae, Cleridae, Histeridae and parasitoids from Braconidae, Ichneumonidae, and Chalcididae were recovered, suggesting a need to conduct further studies to document these species' diversity, parasitism rates and efficacy for possible biological control. PMID- 29584734 TI - Comorbidity health pathways in heart failure patients: A sequences-of-regressions analysis using cross-sectional data from 10,575 patients in the Swedish Heart Failure Registry. AB - BACKGROUND: Optimally treated heart failure (HF) patients often have persisting symptoms and poor health-related quality of life. Comorbidities are common, but little is known about their impact on these factors, and guideline-driven HF care remains focused on cardiovascular status. The following hypotheses were tested: (i) comorbidities are associated with more severe symptoms and functional limitations and subsequently worse patient-rated health in HF, and (ii) these patterns of association differ among selected comorbidities. METHODS AND FINDINGS: The Swedish Heart Failure Registry (SHFR) is a national population based register of HF patients admitted to >85% of hospitals in Sweden or attending outpatient clinics. This study included 10,575 HF patients with patient rated health recorded during first registration in the SHFR (1 February 2008 to 1 November 2013). An a priori health model and sequences-of-regressions analysis were used to test associations among comorbidities and patient-reported symptoms, functional limitations, and patient-rated health. Patient-rated health measures included the EuroQol-5 dimension (EQ-5D) questionnaire and the EuroQol visual analogue scale (EQ-VAS). EQ-VAS score ranges from 0 (worst health) to 100 (best health). Patient-rated health declined progressively from patients with no comorbidities (mean EQ-VAS score, 66) to patients with cardiovascular comorbidities (mean EQ-VAS score, 62) to patients with non-cardiovascular comorbidities (mean EQ-VAS score, 59). The relationships among cardiovascular comorbidities and patient-rated health were explained by their associations with anxiety or depression (atrial fibrillation, odds ratio [OR] 1.16, 95% CI 1.06 to 1.27; ischemic heart disease [IHD], OR 1.20, 95% CI 1.09 to 1.32) and with pain (IHD, OR 1.25, 95% CI 1.14 to 1.38). Associations of non-cardiovascular comorbidities with patient-rated health were explained by their associations with shortness of breath (diabetes, OR 1.17, 95% CI 1.03 to 1.32; chronic kidney disease [CKD, OR 1.23, 95% CI 1.10 to 1.38; chronic obstructive pulmonary disease [COPD], OR 95% CI 1.84, 1.62 to 2.10) and with fatigue (diabetes, OR 1.27, 95% CI 1.13 to 1.42; CKD, OR 1.24, 95% CI 1.12 to 1.38; COPD, OR 1.69, 95% CI 1.50 to 1.91). There were direct associations between all symptoms and patient-rated health, and indirect associations via functional limitations. Anxiety or depression had the strongest association with functional limitations (OR 10.03, 95% CI 5.16 to 19.50) and patient-rated health (mean difference in EQ-VAS score, 18.68, 95% CI -23.22 to -14.14). HF optimizing therapies did not influence these associations. Key limitations of the study include the cross-sectional design and unclear generalisability to other populations. Further prospective HF studies are required to test the consistency of the relationships and their implications for health. CONCLUSIONS: Identification of distinct comorbidity health pathways in HF could provide the evidence for individualised person-centred care that targets specific comorbidities and associated symptoms.

AB - Cell growth is determined by substrate availability and the cell's metabolic capacity to assimilate substrates into building blocks. Metabolic genes that determine growth rate may interact synergistically or antagonistically, and can accelerate or slow growth, depending on genetic background and environmental conditions. We evolved a diverse set of Escherichia coli single-gene deletion mutants with a spectrum of growth rates and identified mutations that generally increase growth rate. Despite the metabolic differences between parent strains, mutations that enhanced growth largely mapped to core transcription machinery, including the beta and beta' subunits of RNA polymerase (RNAP) and the transcription elongation factor, NusA. The structural segments of RNAP that determine enhanced growth have been previously implicated in antibiotic resistance and in the control of transcription elongation and pausing. We further developed a computational framework to characterize how the transcriptional changes that occur upon acquisition of these mutations affect growth rate across strains. Our experimental and computational results provide evidence for cases in which RNAP mutations shift the competitive balance between active transcription and gene silencing. This study demonstrates that mutations in specific regions of RNAP are a convergent adaptive solution that can enhance the growth rate of cells from distinct metabolic states. PMID- 29584735 TI - Prospective memory, retrospective memory, and individual differences in cognitive abilities, personality, and psychopathology. AB - Although individual differences in processing speed, working memory, intelligence, and other cognitive functions were found to explain individual differences in retrospective memory (RetM), much less is known about their relationship with prospective memory (ProM). Moreover, the studies that investigated the relationship between ProM and cognitive functions arrived to contradictory conclusions. The relationship between ProM, personality, and psychopathology is similarly unsettled. Meta-analytic reviews of the relationships of ProM with aging and personality suggest that the contradictory findings may be due to widespread methodological problems plaguing ProM research including the prevalent use of inefficient, unreliable binary measures; widespread ceiling effects; failure to distinguish between various ProM subdomains (e.g., episodic ProM versus vigilance/monitoring); various confounds; and, importantly, small sample sizes, resulting in insufficient statistical power. Accordingly, in a large scale study with nearly 1,200 participants, we investigated the relationship between episodic event-cued ProM, episodic RetM, and fundamental cognitive functions including intelligence, personality, and psychopathology, using reliable continuous measures of episodic event-cued ProM. Our findings show that (a) continuous measures of episodic event-cued ProM were much more reliable than binary measures, (b) episodic event-cued ProM was associated with measures of processing speed, working memory, crystallized and fluid intelligence, as well as RetM, and that such associations were similar for ProM and RetM, (c) personality factors did not improve prediction of neither ProM nor RetM beyond the variance predicted by cognitive ability, (d) symptoms of psychopathology did not improve the prediction of ProM although they slightly improved the prediction of RetM, and (e) participants' sex was not associated with ProM but showed small correlations with RetM. In addition to advancing our theoretical understanding of ProM, our findings highlight the need to avoid common pitfalls plaguing ProM research.

AB - We evaluated the feasibility and safety of nictitating membrane fixation to address reduced contact lens stability by the nictitating membrane in a rabbit model. Under general anesthesia, twelve animals received a horizontal mattress suture between the nictitating membrane and the upper eyelid of one eye. To assess the effects of this technique and secondary side effects, contact lens stability test, Schirmer tear test, tear break-up time measurement, eye tissue pathology and morphology were evaluated. Contact lens stability was increased after nictitating membrane fixation. The percentage of contact lens retention in the nictitating membrane fixed rabbit after 4 hours was 90% whereas that in the untreated rabbit was 42.5%. In addition, there were no significant differences in tear quantity and quality between the fixed and untreated eyes. Furthermore, no remarkable pathological lesions were found in gross observation during the 1 month time period or the following pathological examination. In this study, we demonstrated that nictitating membrane fixation increases contact lens stability without specific side effects using a rabbit model. This minimally invasive procedure could be useful when designing animal models for testing new contact lenses and has potential to apply to other biomaterial research on the ocular surface. PMID- 29584736 TI - Population genomics of Fusarium graminearum reveals signatures of divergent evolution within a major cereal pathogen. AB - The cereal pathogen Fusarium graminearum is the primary cause of Fusarium head blight (FHB) and a significant threat to food safety and crop production. To elucidate population structure and identify genomic targets of selection within major FHB pathogen populations in North America we sequenced the genomes of 60 diverse F. graminearum isolates. We also assembled the first pan-genome for F. graminearum to clarify population-level differences in gene content potentially contributing to pathogen diversity. Bayesian and phylogenomic analyses revealed genetic structure associated with isolates that produce the novel NX-2 mycotoxin, suggesting a North American population that has remained genetically distinct from other endemic and introduced cereal-infecting populations. Genome scans uncovered distinct signatures of selection within populations, focused in high diversity, frequently recombining regions. These patterns suggested selection for genomic divergence at the trichothecene toxin gene cluster and thirteen additional regions containing genes potentially involved in pathogen specialization. Gene content differences further distinguished populations, in that 121 genes showed population-specific patterns of conservation. Genes that differentiated populations had predicted functions related to pathogenesis, secondary metabolism and antagonistic interactions, though a subset had unique roles in temperature and light sensitivity. Our results indicated that F. graminearum populations are distinguished by dozens of genes with signatures of selection and an array of dispensable accessory genes, suggesting that FHB pathogen populations may be equipped with different traits to exploit the agroecosystem. These findings provide insights into the evolutionary processes and genomic features contributing to population divergence in plant pathogens, and highlight candidate genes for future functional studies of pathogen specialization across evolutionarily and ecologically diverse fungi. PMID- 29584738 TI - Conveying facial expressions to blind and visually impaired persons through a wearable vibrotactile device. AB - In face-to-face social interactions, blind and visually impaired persons (VIPs) lack access to nonverbal cues like facial expressions, body posture, and gestures, which may lead to impaired interpersonal communication. In this study, a wearable sensory substitution device (SSD) consisting of a head mounted camera and a haptic belt was evaluated to determine whether vibrotactile cues around the waist could be used to convey facial expressions to users and whether such a device is desired by VIPs for use in daily living situations. Ten VIPs (mean age: 38.8, SD: 14.4) and 10 sighted persons (SPs) (mean age: 44.5, SD: 19.6) participated in the study, in which validated sets of pictures, silent videos, and videos with audio of facial expressions were presented to the participant. A control measurement was first performed to determine how accurately participants could identify facial expressions while relying on their functional senses. After a short training, participants were asked to determine facial expressions while wearing the emotion feedback system. VIPs using the device showed significant improvements in their ability to determine which facial expressions were shown. A significant increase in accuracy of 44.4% was found across all types of stimuli when comparing the scores of the control (mean+/-SEM: 35.0+/-2.5%) and supported (mean+/-SEM: 79.4+/-2.1%) phases. The greatest improvements achieved with the support of the SSD were found for silent stimuli (68.3% for pictures and 50.8% for silent videos). SPs also showed consistent, though not statistically significant, improvements while supported. Overall, our study shows that vibrotactile cues are well suited to convey facial expressions to VIPs in real time. Participants became skilled with the device after a short training session. Further testing and development of the SSD is required to improve its accuracy and aesthetics for potential daily use. PMID- 29584739 TI - Could HE4 level measurements during first-line chemotherapy predict response to treatment among ovarian cancer patients? AB - BACKGROUND: This study assessed the prognostic value of HE4 marker measurements at various stages of first-line chemotherapy for ovarian cancer. METHODS: The study consisted of 90 ovarian cancer patients, including 48 women undergoing primary surgical treatment and 42 patients qualified for neoadjuvant chemotherapy. Each patient underwent HE4 and CA 125 level measurements at the time of diagnosis and subsequently as follows: after surgical treatment, after the third course of adjuvant chemotherapy, before interval cytoreductive surgery and after chemotherapy. The HE4 value was assessed based on the PSF, OS, DFS, surgical outcome, two-year survival and platinum sensitivity. RESULTS: Preoperative HE4 levels were a predictor of platinum sensitivity (AUC- 0.644; p = 0.035) and DFS (AUC = 0.637; p = 0.0492). A univariate logistic regression analysis showed that serum HE4 significantly correlated with PFS (baseline results over median HR = 2.96, p = 0.0009; baseline over 75 percentile HR = 2.44, p = 0.0062; normalization after treatment HR = 0.46, p = 0.0125; 50% reduction before IDS HR = 0.64, p = 0.0017). In the multivariate analysis, normalization after treatment and 50% reduction before IDS significantly influenced the PFS (HR = 0.29, p = 0.00008; HR = 0.23, p = 0.0024). The HE4 levels also correlated with the OS as follows: values below the median (HR = 1.88, p = 0.0087), normalization after chemotherapy (HR = 0.08, p = 0.0003), and 50% reduction before IDS (HR = 0.39, p = 0.0496). CONCLUSIONS: The significant effect of the normalization of the HE4 marker after therapy and 50% reduction of HE4 levels before interval cytoreductive surgery on PFS and OS confirmed that HE4 might be an independent prognostic factor of treatment response. HE4 measurements performed during first line treatment of ovarian cancer may have prognostic significance. PMID- 29584740 TI - Panax quinquefolius saponins combined with dual antiplatelet drug therapy alleviate gastric mucosal injury and thrombogenesis through the COX/PG pathway in a rat model of acute myocardial infarction. AB - OBJECTIVES: Previous studies have found that Panax quinquefolius saponins (PQS) combined with dual antiplatelet therapy (DAPT) of aspirin and clopidogrel enhances antithrombotic effects while reducing gastric mucosal injury induced by DAPT. We investigated the effects of the combined drug therapy (PQS+DAPT) through the COX/PG pathways. METHODS: Acute myocardial infarction (AMI) was induced in Wistar rats by ligation of the left anterior descending (LAD) coronary artery, and the animals were randomly divided into Model, DAPT, and PQS+DAPT groups. Rats in the sham group did not undergo artery ligation. They were intragastrically treated for 14 days. Myocardial infarct size; myocardial pathology; platelet aggregation rate, CD62p activation, concentrations of thromboxane B2 (TXB2), 6 keto-PGF1alpha, tissue plasminogen activator (t-PA), and plasminogen activator inhibitor (PAI), the TXB2/6-keto-PGF1alpha ratio were measured. The ultrastructure of the gastric mucosa was observed by scanning electron microscopy. The expression of PGE2 and 6-keto-PGF1alpha in gastric mucosa was measured by radioimmunoassay, and levels of COX-1, COX-2, and VEGF in gastric mucosa were assessed using immunohistochemistry. RESULTS: The addition of Panax quinquefolius saponins (PQS+DAPT) to standard DAPT therapy significantly decreased the myocardial infarct area, degree of myocardial lesions, TXB2 and PAI levels, and the TXB2/6-keto-PGF1alpha ratio, while increasing 6-keto-PGF1alpha and t-PA levels and reducing the degree of gastric mucosal injury. Expression of PGE2, 6-keto-PGF1alpha, COX-2, and VEGF in the gastric mucosa was upregulated in the PQS+DAPT group compared with the standard DAPT group. CONCLUSION: PQS increases the degree of DAPT inhibition of myocardial necrosis and antiplatelet effects in AMI rats, as well as reducing damage to the gastric mucosa caused by DAPT. The mechanism may be related to inhibition of TXB2 and PAI activity and elevation of 6-keto-PGF1alpha and t-PA levels in blood, and may be associated with upregulated expression of COX-2, PGE2, PGI2, and VEGF in gastric tissue. PMID- 29584741 TI - Genome-wide analysis of codon usage bias in four sequenced cotton species. AB - Codon usage bias (CUB) is an important evolutionary feature in a genome which provides important information for studying organism evolution, gene function and exogenous gene expression. The CUB and its shaping factors in the nuclear genomes of four sequenced cotton species, G. arboreum (A2), G. raimondii (D5), G. hirsutum (AD1) and G. barbadense (AD2) were analyzed in the present study. The effective number of codons (ENC) analysis showed the CUB was weak in these four species and the four subgenomes of the two tetraploids. Codon composition analysis revealed these four species preferred to use pyrimidine-rich codons more frequently than purine-rich codons. Correlation analysis indicated that the base content at the third position of codons affect the degree of codon preference. PR2-bias plot and ENC-plot analyses revealed that the CUB patterns in these genomes and subgenomes were influenced by combined effects of translational selection, directional mutation and other factors. The translational selection (P2) analysis results, together with the non-significant correlation between GC12 and GC3, further revealed that translational selection played the dominant role over mutation pressure in the codon usage bias. Through relative synonymous codon usage (RSCU) analysis, we detected 25 high frequency codons preferred to end with T or A, and 31 low frequency codons inclined to end with C or G in these four species and four subgenomes. Finally, 19 to 26 optimal codons with 19 common ones were determined for each species and subgenomes, which preferred to end with A or T. We concluded that the codon usage bias was weak and the translation selection was the main shaping factor in nuclear genes of these four cotton genomes and four subgenomes. PMID- 29584742 TI - Patient and physician characteristics affect adherence to screening mammography: A population-based cohort study. AB - BACKGROUND: Screening mammograms are widely recommended biennially for women between the ages of 50 and 74. Despite the benefits of screening mammograms, full adherence to recommendations falls below 75% in most developed countries. Many studies have identified individual (obesity, smoking, socio-economic status, and co-morbid conditions) and primary-care physician parameters (physician age, gender, clinic size and cost) that influence adherence, but little data exists from large population studies regarding the interaction of these individual factors. METHODS: We performed a historical cohort study of 44,318 Israeli women age 56-74 using data captured from electronic medical records of a large Israeli health maintenance organization. Univariate analysis was used to examine the association between each factor and adherence (none, partial or full) with screening recommendations between 2008-2014. Multivariate analysis was used to examine the significance of these factors in combination, using binary and multinomial logistic regression. RESULTS: Among 44,318 women, 42%, 43% and 15% were fully, partially and non-adherent to screening recommendations, respectively. Factors associated with inferior adherence identified in our population included: smoking, obesity, low body weight, low socio-economic status, depression, diabetes mellitus and infrequent physician visits, while, women with ischemic heart disease, female physicians, physicians between the ages of 40 and 60, and medium-sized clinics were associated with higher screening rates. Most factors remained significant in the multivariate analysis. CONCLUSIONS: Both individual and primary-care physician factors contribute to adherence to mammography screening guidelines. Strategies to improve adherence and address disparities in mammography utilization will need to address these factors. PMID- 29584743 TI - Partner notification outcomes after integration of an on-site disease intervention specialist at a sexually transmitted disease clinic. AB - BACKGROUND: Partner notification services (PNS) are highly effective in reducing transmission of sexually transmitted diseases (STDs). We assessed outcomes of PNS before and after integration of an on-site disease intervention specialist (DIS) at a publicly-funded STD clinic. METHODS: From August 2014 to December 2015, patients testing positive for infectious syphilis or gonorrhea at the Rhode Island STD Clinic were referred to on-site DIS for partner notification. Data on PNS outcomes were reviewed for eight months before integration of DIS at the clinic and compared to eight months after. RESULTS: Of the 145 index patients referred for PNS during the study period (n = 58 before DIS integration, n = 87 after), 86% were interviewed. DIS integration resulted in a significantly greater proportion of index patients interviewed overall (92% versus 76%, p<0.01), on the day of diagnosis (85% versus 61%; p<0.01), and in person at the STD clinic (64% versus 11%; p<0.01). However, there was no significant difference in number of sexual partners named or treated. CONCLUSIONS: Integrating DIS at a publicly funded STD clinic resulted in a greater number of index cases interviewed, a greater number interviewed in person, and a greater number interviewed on the day of diagnosis. Challenges remain in identifying and engaging partners for treatment. PMID- 29584744 TI - Availability of patient-centered cancer support services: A statewide survey of cancer centers. AB - The Institute of Medicine recommended in their landmark report "From Cancer Patient to Cancer Survivor: Lost in Transition" that services to meet the needs of cancer patients should extend beyond physical health issues to include functional and psychosocial consequences of cancer. However, no systems exist in the US to support state-level data collection on availability of support services for cancer patients. Developing a mechanism to systematically collect these data and document service availability is essential for guiding comprehensive cancer control planning efforts. This study was carried out to develop a protocol for implementing a statewide survey of all Commission on Cancer (CoC) accredited cancer centers in South Carolina and to implement the survey to examine availability of patient support services within the state. We conducted a cross sectional survey of CoC-certified cancer centers in South Carolina. An administrator at each center completed a survey on availability of five services: 1) patient navigation; 2) distress screening; 3) genetic risk assessment and counseling, 4) survivorship care planning; and 5) palliative care. Completed surveys were received from 16 of 17 eligible centers (94%). Of the 16 centers, 44% reported providing patient navigation; 31% reported conducting distress screening; and 44% reported providing genetic risk assessment and counseling. Over 85% of centers reported having an active palliative care program, palliative care providers and a hospice program, but fewer had palliative outpatient services (27%), palliative inpatient beds (50%) or inpatient consultation teams (31%). This was a small, yet systematic survey in one state. This study demonstrated a practical method for successfully monitoring statewide availability of cancer patient support services, including identifying service gaps. PMID- 29584745 TI - Derivation of intermediate to silicic magma from the basalt analyzed at the Vega 2 landing site, Venus. AB - Geochemical modeling using the basalt composition analyzed at the Vega 2 landing site indicates that intermediate to silicic liquids can be generated by fractional crystallization and equilibrium partial melting. Fractional crystallization modeling using variable pressures (0.01 GPa to 0.5 GPa) and relative oxidation states (FMQ 0 and FMQ -1) of either a wet (H2O = 0.5 wt%) or dry (H2O = 0 wt%) parental magma can yield silicic (SiO2 > 60 wt%) compositions that are similar to terrestrial ferroan rhyolite. Hydrous (H2O = 0.5 wt%) partial melting can yield intermediate (trachyandesite to andesite) to silicic (trachydacite) compositions at all pressures but requires relatively high temperatures (>= 950 degrees C) to generate the initial melt at intermediate to low pressure whereas at high pressure (0.5 GPa) the first melts will be generated at much lower temperatures (< 800 degrees C). Anhydrous partial melt modeling yielded mafic (basaltic andesite) and alkaline compositions (trachybasalt) but the temperature required to produce the first liquid is very high (>= 1130 degrees C). Consequently, anhydrous partial melting is an unlikely process to generate derivative liquids. The modeling results indicate that, under certain conditions, the Vega 2 composition can generate silicic liquids that produce granitic and rhyolitic rocks. The implication is that silicic igneous rocks may form a small but important component of the northeast Aphrodite Terra. PMID- 29584746 TI - Communication calls produced by electrical stimulation of four structures in the guinea pig brain. AB - One of the main central processes affecting the cortical representation of conspecific vocalizations is the collateral output from the extended motor system for call generation. Before starting to study this interaction we sought to compare the characteristics of calls produced by stimulating four different parts of the brain in guinea pigs (Cavia porcellus). By using anaesthetised animals we were able to reposition electrodes without distressing the animals. Trains of 100 electrical pulses were used to stimulate the midbrain periaqueductal grey (PAG), hypothalamus, amygdala, and anterior cingulate cortex (ACC). Each structure produced a similar range of calls, but in significantly different proportions. Two of the spontaneous calls (chirrup and purr) were never produced by electrical stimulation and although we identified versions of chutter, durr and tooth chatter, they differed significantly from our natural call templates. However, we were routinely able to elicit seven other identifiable calls. All seven calls were produced both during the 1.6 s period of stimulation and subsequently in a period which could last for more than a minute. A single stimulation site could produce four or five different calls, but the amygdala was much less likely to produce a scream, whistle or rising whistle than any of the other structures. These three high-frequency calls were more likely to be produced by females than males. There were also differences in the timing of the call production with the amygdala primarily producing calls during the electrical stimulation and the hypothalamus mainly producing calls after the electrical stimulation. For all four structures a significantly higher stimulation current was required in males than females. We conclude that all four structures can be stimulated to produce fictive vocalizations that should be useful in studying the relationship between the vocal motor system and cortical sensory representation. PMID- 29584747 TI - Are narcissists more attracted to people in relationships than to people not in relationships? AB - Does grandiose narcissism predict greater attraction for others in relationships? We examined this question by replicating previous work implicating grandiose narcissists as mate poachers (Studies 1 and 2). We then used an experimental paradigm (Studies 3 and 4) to assess the extent to which grandiose narcissists indicate a greater interest in someone who is already in a relationship compared to someone who is single. Results suggest that although grandiose narcissism related to reports of more frequent mate poaching attempts, grandiose narcissists did not appear to be more interested in taking someone away from an existing relationship. Instead, participants took their own relationship status into consideration (rather than the relationship status of a target) when evaluating their interest in a target for a short-term fling or a long-term relationship. Thus, although grandiose narcissists report more frequent mate poaching attempts, they do not appear to be more interested in people in relationships compared to those who are single. PMID- 29584748 TI - Chemical characterization and biological activity in young sesame leaves (Sesamum indicum L.) and changes in iridoid and polyphenol content at different growth stages. AB - Three iridoids (lamalbid (I1), sesamoside (I2) and shanzhiside methyl ester (I3)) and seven polyphenols (cistanoside F (P1), chlorogenic acid (P2), pedalitin-6-O laminaribioside (P3), pedaliin (P4), isoacteoside (P6), pedalitin (P7) and martynoside (P8)) were identified in young sesame leaves (Sesamum indicum L.) other than the acteoside (P5) reported previously. P3 was a new compound, and I1, I3, P2 and P8 were found in a species of Sesamum for the first time. HPLC analyses revealed that the compounds I1 (0.29-1.75% of dry leaves), I2 (0.38 0.87%), I3 (0.04-1.07%), P4 (0.01-2.05%) and P5 (0.13-4.86%) were present primarily in young sesame leaves and were found in plants cultivated on different farms (plant height, 30-70 cm). Of the identified compounds, P5 and P6 showed high 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, oxygen radical absorbance capacity (ORAC), and in vitro antiglycation activities. Given its content, P5 makes a major contribution to the biological activities of young sesame leaves. The compounds were examined at six different growth stages of plants cultured in a greenhouse to determine the optimum harvest stage and for end-use assessment. P5 accumulated in the leaves during growth, and the content reached a maximum of 12.9% of dry leaves in the 4th stage (plant height, 74.5+/ 9.7 cm), which is one of the highest percentages reported in plants from nature. PMID- 29584749 TI - Effectiveness of integrated care model for type 2 diabetes: A population-based study in Reggio Emilia (Italy). AB - AIMS: To compare the effectiveness of integrated care with that of the diabetes clinic care model in terms of mortality and hospitalisation of type 2 diabetes patients with low risk of complications. METHODS: Out of 27234 people with type 2 diabetes residing in the province of Reggio Emilia on 31/12/2011, 3071 were included in this cohort study as eligible for integrated care (i.e., low risk of complications) and cared for with the same care model for at least two years. These patients were followed up from 2012 to 2016, for all-cause and diabetes related mortality and hospital admissions. We performed a Poisson regression model, using the proportion of eligible patients included in the integrated care model for each general practitioner as an instrumental variable. RESULTS: 1700 patients were cared for by integrated care and 1371 by diabetes clinics. Mortality rate ratios were 0.83 (95%CI 0.60-1.13) and 0.95 (95%CI 0.54-1.70) for all-cause and cardiovascular mortality, respectively, and incidence rate ratios were 0.90 (95%CI 0.76-1.06) and 0.91 (95%CI 0.69-1.20) for all-cause and cardiovascular disease hospitalisation, respectively. CONCLUSION: For low risk patients with type 2 diabetes, the integrated care model involving both general practitioner and diabetes clinic professionals showed similar mortality and hospitalisation as a model with higher use of specialized care in an exclusively diabetes clinic setting. PMID- 29584750 TI - Unexpected binding behaviors of bacterial Argonautes in human cells cast doubts on their use as targetable gene regulators. AB - Prokaryotic Argonaute proteins (pAgos) have been proposed as an alternative to the CRISPR/Cas9 platform for gene editing. Although Argonaute from Natronobacterium gregoryi (NgAgo) was recently shown unable to cleave genomic DNA in mammalian cells, the utility of NgAgo or other pAgos as a targetable DNA binding platform for epigenetic editing has not been explored. In this report, we evaluated the utility of two prokaryotic Argonautes (NgAgo and TtAgo) as DNA guided DNA-binding proteins. NgAgo showed no meaningful binding to chromosomal targets, while TtAgo displayed seemingly non-specific binding to chromosomal DNA even in the absence of guide DNA. The observed lack of DNA-guided targeting and unexpected guide-independent genome sampling under the conditions in this study provide evidence that these pAgos might be suitable for neither gene nor epigenome editing in mammalian cells. PMID- 29584751 TI - Accuracy of speckle tracking in the context of stress echocardiography in short axis view: An in vitro validation study. AB - AIM: This study aimed to test the accuracy of a speckle tracking algorithm to assess myocardial deformation in a large range of heart rates and strain magnitudes compared to sonomicrometry. METHODS AND RESULTS: Using a tissue mimicking phantom with cyclic radial deformation, radial strain derived from speckle tracking (RS-SpT) of the upper segment was assessed in short axis view by conventional echocardiography (Vivid q, GE) and post-processed with clinical software (EchoPAC, GE). RS-SpT was compared with radial strain measured simultaneously by sonomicrometers (RS-SN). Radial strain was assessed with increasing deformation rates (60 to 160 beats/min) and increasing pulsed volumes (50 to 100 ml/beat) to simulate physiological changes occurring during stress echocardiography. There was a significant correlation (R2 = 0.978, P <0.001) and a close agreement (bias +/- 2SD, 0.39 +/- 1.5%) between RS-SpT and RS-SN. For low strain values (<15%), speckle tracking showed a small but significant overestimation of radial strain compared to sonomicrometers. Two-way analysis of variance did not show any significant effect of the deformation rate. For RS-SpT, the feasibility was excellent and the intra- and inter-observer variability were low (the intraclass correlation coefficients were 0.96 and 0.97, respectively). CONCLUSIONS: Speckle tracking demonstrated a good correlation with sonomicrometry for the assessment of radial strain independently of the heart rate and strain magnitude in a physiological range of values. Though speckle tracking seems to be a reliable and reproducible technique to assess myocardial deformation variations during stress echocardiography, further studies are mandated to analyze the impact of angulated and artefactual out-of-plane motions and inter-vendor variability. PMID- 29584752 TI - Use of adjuvant chemotherapy in patients with stage III colon cancer in Puerto Rico: A population-based study. AB - OBJECTIVE: This study aims to examine factors associated with the use of adjuvant chemotherapy and the use of oxaliplatin after curative resection in stage III colon cancer patients and assesses the effect of their use in three-year survival. METHODS: This retrospective cohort study was conducted using Puerto Rico Central Cancer Registry-Health Insurance Linkage Database. The study cohort consisted of stage III colon cancer patients with a curative surgery in the period 2008-2012. Multivariate logistic regression was used to estimate adjusted odds ratios. Kaplan-Meier methods and Cox proportional hazards models were used to assess the association between adjuvant chemotherapy and oxaliplatin use and overall survival and risk of death, respectively. RESULTS: Overall, 75% of the study population received adjuvant chemotherapy during the study period. Factors statistically associated with receiving adjuvant chemotherapy within four months after resection included being married (adjusted odds ratio [AOR] 1.64; 95% CI 1.18-2.28; p = 0.003), and being enrolled in Medicare (AOR 1.68; 95% CI: 1.03 2.75; p = 0.039) or Medicaid and Medicare dual eligible (AOR 1.66; 95% CI: 1.06 2.60; p = 0.028). However, patients aged >=70 years were less likely to receive adjuvant chemotherapy (AOR 0.22; 95%CI 0.14-0.36; p<0.001). DISCUSSION: We observed a significant reduction in mortality in adjuvant chemotherapy treated patients. Similarly, patients <70 years treated with oxaliplatin had significantly lower risk of death than those who did not, although for patients >=70 years no statistical significance was achieved. Future studies should assess effective interventions to reduce barriers to access guideline-based recommended colon cancer treatment.

AB - Various approaches have been proposed to address the delineation of built-up areas for a wide range of applications. Recently developed approaches are based on the increasing availability of road network data. However, most approaches have employed one or more parameters to divide built-up from non-built-up areas. Very few studies have discussed how to determine appropriate thresholds for such parameters. This study employed an empirical approach for threshold determination, and validated that the approach is applicable for the delineation of built-up areas using road network data. A series of experiments were designed to investigate the most-appropriate thresholds (determined using a similarity measure) for multiple parameters of three existing approaches (street blocks, grid-based, and kernel density) with regard to different administrative regions and cities/towns. The results show that in most cases, the most-appropriate thresholds or ranges for different subdivisions are either identical or overlap thus validating the use of the most-appropriate thresholds to delineate built-up areas for one or multiple small subdivisions and, by inference, for a much larger region.

AB - Sensorineural hearing loss (SNHL) can be overcome by electrical stimulation of spiral ganglion neurons (SGNs) via a cochlear implant (CI). Restricted CI performance results from the spatial gap between the SGNs and the electrode, but the efficacy of CI is also limited by the degeneration of SGNs as one consequence of SHNL. In the healthy cochlea, the survival of SGNs is assured by endogenous neurotrophic support. Several applications of exogenous neurotrophic supply have been shown to reduce SGN degeneration in vitro and in vivo. In the present study, nanoporous silica nanoparticles (NPSNPs), with an approximate diameter of <100 nm, were loaded with the brain-derived neurotrophic factor (BDNF) to test their efficacy as long-term delivery system for neurotrophins. The neurotrophic factor was released constantly from the NPSNPs over a release period of 80 days when the surface of the nanoparticles had been modified with amino groups. Cell culture investigations with NIH3T3 fibroblasts attest a good general cytocompatibility of the NPSNPs. In vitro experiments with SGNs indicate a significantly higher survival rate of SGNs in cell cultures that contained BDNF-loaded nanoparticles compared to the control culture with unloaded NPSNPs (p<0.001). Importantly, also the amounts of BDNF released up to a time period of 39 days increased the survival rate of SGNs. Thus, NPSNPs carrying BDNF are suitable for the treatment of inner ear disease and for the protection and the support of SGNs. Their nanoscale nature and the fact that a direct contact of the nanoparticles and the SGNs is not necessary for neuroprotective effects, should allow for the facile preparation of nanocomposites, e.g., with biocompatible polymers, to install coatings on implants for the realization of implant-based growth factor delivery systems.

AB - Multiechelon supply chains are complex logistics systems that require flexibility and coordination at a tactical level to cope with environmental uncertainties in an efficient and effective manner. To cope with these challenges, mathematical programming models are developed to evaluate supply chain flexibility. However, under uncertainty, supply chain models become complex and the scope of flexibility analysis is generally reduced. This paper presents a unified approach that can evaluate the flexibility of a four-echelon supply chain via a robust stochastic programming model. The model simultaneously considers the plans of multiple business divisions such as marketing, logistics, manufacturing, and procurement, whose goals are often conflicting. A numerical example with deterministic parameters is presented to introduce the analysis, and then, the model stochastic parameters are considered to evaluate flexibility. The results of the analysis on supply, manufacturing, and distribution flexibility are presented. Tradeoff analysis of demand variability and service levels is also carried out. The proposed approach facilitates the adoption of different management styles, thus improving supply chain resilience. The model can be extended to contexts pertaining to supply chain disruptions; for example, the model can be used to explore operation strategies when subtle events disrupt supply, manufacturing, or distribution.

AB - BACKGROUND: Little is known regarding the mechanisms underlying the loss of tolerance in the early and preclinical stages of autoimmune diseases. The aim of this work was to identify the transcriptional profile and signaling pathways associated to non-treated early rheumatoid arthritis (RA) and subjects at high risk. Several biomarker candidates for early RA are proposed. METHODS: Whole blood total RNA was obtained from non-treated early RA patients with <1 year of evolution as well as from healthy first-degree relatives of patients with RA (FDR) classified as ACCP+ and ACCP- according to their antibodies serum levels against cyclic citrullinated peptides. Complementary RNA (cRNA) was synthetized and hybridized to high-density microarrays. Data was analyzed in Genespring Software and functional categories were assigned to a specific transcriptome identified in subjects with RA and FDR ACCP positive. Specific signaling pathways for genes associated to RA were identified. Gene expression was evaluated by qPCR. Receiver operating characteristic (ROC) analysis was used to evaluate these genes as biomarkers. RESULTS: A characteristic transcriptome of 551 induced genes and 4,402 repressed genes were identified in early RA patients. Bioinformatics analysis of the data identified a specific transcriptome in RA patients. Moreover, some overlapped transcriptional profiles between patients with RA and ACCP+ were identified, suggesting an up-regulated distinctive transcriptome from the preclinical stages up to progression to an early RA state. A total of 203 pathways have up-regulated genes that are shared between RA and ACCP+. Some of these genes show potential to be used as progression biomarkers for early RA with area under the curve of ROC > 0.92. These genes come from several functional categories associated to inflammation, Wnt signaling and type I interferon pathways. CONCLUSION: The presence of a specific transcriptome in whole blood of RA patients suggests the activation of a specific inflammatory transcriptional signature in early RA development. The set of overexpressed genes in early RA patients that are shared with ACCP+ subjects but not with ACCP- subjects, can represent a transcriptional signature involved with the transition of a preclinical to a clinical RA stage. Some of these particular up-regulated and down-regulated genes are related to inflammatory processes and could be considered as biomarker candidates for disease progression in subjects at risk to develop RA. PMID- 29584757 TI - Transcriptome analysis of genetically matched human induced pluripotent stem cells disomic or trisomic for chromosome 21. AB - Trisomy of chromosome 21, the genetic cause of Down syndrome, has the potential to alter expression of genes on chromosome 21, as well as other locations throughout the genome. These transcriptome changes are likely to underlie the Down syndrome clinical phenotypes. We have employed RNA-seq to undertake an in depth analysis of transcriptome changes resulting from trisomy of chromosome 21, using induced pluripotent stem cells (iPSCs) derived from a single individual with Down syndrome. These cells were originally derived by Li et al, who genetically targeted chromosome 21 in trisomic iPSCs, allowing selection of disomic sibling iPSC clones. Analyses were conducted on trisomic/disomic cell pairs maintained as iPSCs or differentiated into cortical neuronal cultures. In addition to characterization of gene expression levels, we have also investigated patterns of RNA adenosine-to-inosine editing, alternative splicing, and repetitive element expression, aspects of the transcriptome that have not been significantly characterized in the context of Down syndrome. We identified significant changes in transcript accumulation associated with chromosome 21 trisomy, as well as changes in alternative splicing and repetitive element transcripts. Unexpectedly, the trisomic iPSCs we characterized expressed higher levels of neuronal transcripts than control disomic iPSCs, and readily differentiated into cortical neurons, in contrast to another reported study. Comparison of our transcriptome data with similar studies of trisomic iPSCs suggests that trisomy of chromosome 21 may not intrinsically limit neuronal differentiation, but instead may interfere with the maintenance of pluripotency. PMID- 29584758 TI - Experimental study of isolas in nonlinear systems featuring modal interactions. AB - The objective of the present paper is to provide experimental evidence of isolated resonances in the frequency response of nonlinear mechanical systems. More specifically, this work explores the presence of isolas, which are periodic solutions detached from the main frequency response, in the case of a nonlinear set-up consisting of two masses sliding on a horizontal guide. A careful experimental investigation of isolas is carried out using responses to swept-sine and stepped-sine excitations. The experimental findings are validated with advanced numerical simulations combining nonlinear modal analysis and bifurcation monitoring. In particular, the interactions between two nonlinear normal modes are shown to be responsible for the creation of the isolas. PMID- 29584759 TI - Anti-inflammatory cytokine and angiogenic factors levels in vitreous samples of diabetic retinopathy patients. AB - Evaluation of cytokines in patients with diabetic retinopathy (DR) is important for the identification of future additive or alternative treatment options. Therefore, vitreous samples were obtained from patients with DR and patients with macular hole or macular pucker (control group) during 23-gauge-vitrectomy (n = 17/group). The levels of three pro-inflammatory (IL-1beta, IL-6, IFN-gamma) and pleiotropic cytokines (IL-2, IL-4, IL-13) as well as VEGF, VEGF-A, and PGF were measured using an enzyme linked immunosorbent assay (ELISA). IL-1beta (p = 0.02) and IFN-gamma (p = 0.04), two of the three tested pro-inflammatory cytokines, were elevated in the DR patients, while IL-6 (p = 0.51) level was comparable in both groups. Moreover, in DR samples, a trend towards an IL-13 down-regulation (p = 0.36) was observable. The IL-2 (p = 0.62) and IL-4 (p = 0.78) levels were comparable in both groups. All analyzed angiogenetic factors were up-regulated in DR patients (VEGF: p<0.001; VEGF-A: p = 0.002; PGF: p<0.001). The up-regulation of angiogenetic factors underline their importance in DR development. However, the interaction of the other cytokines showed an interesting pattern. Pro inflammatory cytokines were also up-regulated, which could be evidence for inflammation processes in the diabetic retina. Furthermore, it seems that a counter response of immunomodulatory cytokines is in an initial process, but not strong enough to regulate the processes. Therefore, to support these anti inflammatory mechanisms might be additive treatment option in the future. PMID- 29584760 TI - The influence of transcript assembly on the proteogenomics discovery of microproteins. AB - Proteogenomics methods have identified many non-annotated protein-coding genes in the human genome. Many of the newly discovered protein-coding genes encode peptides and small proteins, referred to collectively as microproteins. Microproteins are produced through ribosome translation of small open reading frames (smORFs). The discovery of many smORFs reveals a blind spot in traditional gene-finding algorithms for these genes. Biological studies have found roles for microproteins in cell biology and physiology, and the potential that there exists additional bioactive microproteins drives the interest in detection and discovery of these molecules. A key step in any proteogenomics workflow is the assembly of RNA-Seq data into likely mRNA transcripts that are then used to create a searchable protein database. Here we demonstrate that specific features of the assembled transcriptome impact microprotein detection by shotgun proteomics. By tailoring transcript assembly for downstream mass spectrometry searching, we show that we can detect more than double the number of high-quality microprotein candidates and introduce a novel open-source mRNA assembler for proteogenomics (MAPS) that incorporates all of these features. By integrating our specialized assembler, MAPS, and a popular generalized assembler into our proteogenomics pipeline, we detect 45 novel human microproteins from a high quality proteogenomics dataset of a human cell line. We then characterize the features of the novel microproteins, identifying two classes of microproteins. Our work highlights the importance of specialized transcriptome assembly upstream of proteomics validation when searching for short and potentially rare and poorly conserved proteins. PMID- 29584761 TI - The first mitochondrial genomes for Pyralinae (Pyralidae) and Glaphyriinae (Crambidae), with phylogenetic implications of Pyraloidea. AB - In the present study, we report five complete and one nearly complete mitochondrial genomes of the Pyraloidea including the first representatives from the Pyralinae (Pyralidae) and Glaphyriinae (Crambidae). We also conduct a comparative analysis of mitogenomic features of this group. Our results show that Pyraloidea mitogenomes evolved under a common trend found in lepidopteran mitogenomes and share several typical genomic characters. The extra conserved blocks are identified in the Pyraloidea control region, and diverse missing codons formed another unique trait within Pyraloidea mitogenome. Furthermore, we reconstruct the mitogenomic phylogeny of Pyraloidea and confirm the phylogenetic position of Pyralinae and Glaphyriinae within the Pyraloidea using BI and ML method based on multiple mitochondrial datasets. PMID- 29584762 TI - Generational changes in multiple sclerosis phenotype in North African immigrants in France: A population-based observational study. AB - BACKGROUND: The incidence of multiple sclerosis (MS) changes from generation to generation in ethnically different immigrants compared with native-born people. We aimed to determine whether there are generational changes in MS phenotypes among North African immigrants in France. METHODS: Cohort study with data from a population-based MS registry to compare the clinical characteristics of 80 first (NAG1) and 167 second (NAG2) generation North Africans with MS living in France with 5200 native-born Europeans. Adjusted Cox models were used to test the association between scores of 3 and 6 on the expanded disability status scale (EDSS) and the "origin/generation" variable. RESULTS: Cox models for EDSS scores 3 and 6 showed a higher risk of score 3 (hazard ratio = 1.738, 95% confidence interval 1.237 to 2.444; P = .002) and 6 (hazard ratio = 2.372, 95% confidence interval 1.626 to 3.462; P<.0001) for NAG1 than Europeans. Being NAG2 was not significantly associated with higher hazards of scores 3 and 6. CONCLUSIONS: We found two different phenotypes among NAG1 and NAG2 MS patients in France. NAG1, but not NAG2, have a higher risk of disability than Europeans. This raises the question of environmental factors in MS expression, and advocates appropriate patient management according to generation in immigrants. PMID- 29584763 TI - Child injuries in Ethiopia: A review of the current situation with projections. AB - BACKGROUND: Heavy burden of child injuries and lack of policy response in Ethiopia call for an improved understanding of the situation and development of action plans from multiple governmental agencies and stakeholders. METHODS: A consortium of international and Ethiopian researchers and stakeholders used extensive literature review and mixed analytical methods to estimate and project the burden of fatal and non-fatal child unintentional injuries in Ethiopia from 2015 to 2030. Estimates were derived for children aged 0-14 years. Data sources include a longitudinal study conducted by the Central Statistics Agency of Ethiopia and the World Bank as well as model-based estimates from World Health Organization 2017 and Global Burden of Disease 2016 project. RESULTS: Injuries caused about 25 thousand deaths among 0-14-year olds in Ethiopia in 2015. The leading cause of fatal child unintentional injuries in Ethiopia was road-traffic injuries, followed by fire, heat and hot substances and drowning. The death rate due to injuries among 0-14 years olds was about 50 percent higher in males than females. Rural children were exposed to a greater risk of injury than their urban peers. The longitudinal survey suggests that the incidence rate of child injuries increased during the period 2011-2014. The annual mortality caused by injuries is projected to increase from 10,697 in 2015 to 11,279 in 2020 and 11,989 in 2030 among children under 5 years, an increase of 12 percentage points in 15 years. The number of deaths among 0-14-year olds will be 26,463, 27,807, and 30,364 respectively in 2015, 2020, and 2030. CONCLUSIONS: As the first multisectoral collaboration on child injuries in Ethiopia, this study identified gaps in understanding of the burden of child injuries in Ethiopia. In consultation with Ethiopian government and other stakeholders, we propose starting an injury surveillance system at health clinics and hospitals and building an intervention package based on existing platforms. PMID- 29584764 TI - Effects of a combination of plant bioactive lipid compounds and biotin compared with monensin on body condition, energy metabolism and milk performance in transition dairy cows. AB - The aim of this study was to test whether a combination of plant bioactive lipid compounds (also termed 'essential oils') and biotin (PBLC+B) could decrease the mobilization of body reserves and ketosis incidence in postpartum dairy cows. We compared non-supplemented control (CON) cows with cows receiving monensin (MON) as a controlled-release capsule at d -21, and with cows receiving PBLC+B from day (d) -21 before calving until calving (Phase 1) and further until d 37 after calving (Phase 2), followed by PBLC+B discontinuation from d 38 to d 58 (Phase 3). The PBLC+B cows had higher body weight and higher back fat thickness than CON cows and lesser body weight change than MON and CON cows in Phase 3. Body condition score was not different among groups. Milk protein concentration tended to be higher on the first herd test day in PBLC+B vs. CON cows. Milk fat concentration tended to be highest in PBLC+B cows throughout Phases 2 and 3, with significantly higher values in PBLC+B vs. MON cows on the second herd test day. Yields of energy-corrected milk were higher in PBLC+B vs. CON and MON cows in Phase 2 and higher in PBLC+B and MON cows vs. CON cows in Phase 3. The incidence of subclinical ketosis was 83%, 61% and 50% in CON, PBLC+B and MON cows, respectively, with lower mean beta-hydroxybutyrate values in MON than in PBLC+B cows in Phase 1 prepartum. The serum triglyceride concentration was higher in PBLC+B vs. CON cows on d 37. No differences were observed in serum glucose, urea, non-esterified fatty acids, cholesterol and bilirubin concentrations. Aspartate transaminase and gamma-glutamyltranspeptidase but not glutamate dehydrogenase activities tended to be highest in MON and lowest in PBLC+B in Phase 2. We conclude that PBLC+B prevent body weight loss after parturition and are associated with similar ketosis incidence and partly higher yields of energy corrected milk compared to MON supplementation of dairy cows.

PMID- 29584765 TI - Dissimilar flexibility of alpha and beta subunits of human adult hemoglobin influences the protein dynamics and its alteration induced by allosteric effectors. AB - The general question by what mechanism an "effector" molecule and the hemes of hemoglobin interact over widely separated intramolecular distances to change the oxygen affinity has been extensively investigated, and still has remained of central interest. In the present work we were interested in clarifying the general role of the protein matrix and its dynamics in the regulation of human adult hemoglobin (HbA). We used a spectroscopy approach that yields the compressibility (kappa) of the protein matrix around the hemes of the subunits in HbA and studied how the binding of heterotropic allosteric effectors modify this parameter. kappa is directly related to the variance of volume fluctuation, therefore it characterizes the molecular dynamics of the protein structure. For the experiments the heme groups either in the alpha or in the beta subunits of HbA were replaced by fluorescent Zn-protoporphyrinIX, and series of fluorescence line narrowed spectra were measured at varied pressures. The evaluation of the spectra yielded the compressibility that showed significant dynamic asymmetry between the subunits: kappa of the alpha subunit was 0.17+/-0.05/GPa, while for the beta subunit it was much higher, 0.36+/-0.07/GPa. The heterotropic effectors, chloride ions, inositol hexaphosphate and bezafibrate did not cause significant changes in kappa of the alpha subunits, while in the beta subunits the effectors lead to a significant reduction down to 0.15+/-0.04/GPa. We relate our results to structural data, to results of recent functional studies and to those of molecular dynamics simulations, and find good agreements. The observed asymmetry in the flexibility suggests a distinct role of the subunits in the regulation of Hb that results in the observed changes of the oxygen binding capability. PMID- 29584768 TI - Global nutrition 1990-2015: A shrinking hungry, and expanding fat world. AB - OBJECTIVES: Following its publication in 2008, the Global Nutritional Index (GNI) which captures the triple burden of malnutrition, has been updated to assess the overall nutritional status and nutritional trends of countries, regions and the world, including both under-nutrition and over-nutrition. METHODS: The GNI was modeled on the Human Development Index, using geometric means of three normalized indicators: protein-energy malnutrition (PEM, measured by Disability-Adjusted Life Years (DALYs) from PEM), micronutrient deficiency (MID, measured by DALYs from MID), and penalizing obesity (percent female obesity). GNI (range 0-1) was calculated from 1990-2015 for 186 countries, in seven World Bank income and WHO region groupings. RESULTS: World GNI increased from 0.433 to 0.473 as decreased deficits overcompensated for the rise in obesity. GNI for African low- and middle income countries (LMIC) (median 0.301 to 0.392) and South-East Asian LMIC (0.456 to 0.564) improved significantly (P<0.001), while for high-income countries (0.657 to 0.611) worsened significantly (P<0.001). GNI for American LMIC (0.459 to 0.457), European LMIC (0.571 to 0.575), Eastern Mediterranean LMIC (0.484 to 0.483) and Western Pacific LMIC (0.433 to 0.494) were unchanged. The disaggregation of the GNI showed that in nearly all the seven country groups there was a significant decrease in both PEM and MID (all P<0.01) (except in HIC where only PEM dropped), and a significant increase in obesity (all P<0.001). CONCLUSION: These trends are the result of the reciprocal changes between decreased under-nutrition and increased over-nutrition, which has become a major cause of malnutrition worldwide. We suggest, therefore, that future Sustainable Development Goals should include alongside "zero hunger"-"reduce obesity". PMID- 29584767 TI - 4000 years of human dietary evolution in central Germany, from the first farmers to the first elites. AB - Investigation of human diet during the Neolithic has often been limited to a few archaeological cultures or single sites. In order to provide insight into the development of human food consumption and husbandry strategies, our study explores bone collagen carbon and nitrogen isotope data from 466 human and 105 faunal individuals from 26 sites in central Germany. It is the most extensive data set to date from an enclosed geographic microregion, covering 4,000 years of agricultural history from the Early Neolithic to the Early Bronze Age. The animal data show that a variety of pastures and dietary resources were explored, but that these changed remarkably little over time. In the human delta15N however we found a significant increase with time across the different archaeological cultures. This trend could be observed in all time periods and archaeological cultures (Bell Beaker phenomenon excluded), even on continuously populated sites. Since there was no such trend in faunal isotope values, we were able largely to exclude manuring as the cause of this effect. Based on the rich interdisciplinary data from this region and archaeological period we can argue that meat consumption increased with the increasing duration of farming subsistence. In delta13C, we could not observe any clear increasing or decreasing trends during the archaeological time periods, either for humans or for animals, which would have suggested significant changes in the environment and landscape use. We discovered sex-related dietary differences, with males of all archaeological periods having higher delta15N values than females, and an age-related increasing consumption of animal protein. An initial decrease of delta15N-values at the age of 1-2 years reveals partial weaning, while complete weaning took place at the age of 3-4 years. PMID- 29584769 TI - Development of a repeat-exposure penile SHIV infection model in macaques to evaluate biomedical preventions against HIV. AB - Penile acquisition of HIV infection contributes substantially to the global epidemic. Our goal was to establish a preclinical macaque model of penile HIV infection for evaluating the efficacy of new HIV prevention modalities. Rhesus macaques were challenged once or twice weekly with consistent doses of SHIVsf162P3 (a chimeric simian-human immunodeficiency virus containing HIV env) ranging from 4-600 TCID50 (50% tissue culture infective dose), via two penile routes, until systemic SHIV infection was confirmed. One route exposed the inner foreskin, glans and urethral os to virus following deposition into the prepuce (foreskin) pouch. The second route introduced the virus non-traumatically into the distal urethra only. Single-route challenges resulted in dose-dependent rates of SHIV acquisition informing selection of optimal SHIV dosing. Concurrent SHIV challenges via the prepuce pouch (200 TCID50) and urethra (16 TCID50) resulted in infection of 100% (10/10) animals following a median of 2.5 virus exposures (range, 1-12). We describe the first rhesus macaque repeat-exposure SHIV challenge model of penile HIV acquisition. Utilization of the model should further our understanding of penile HIV infection and facilitate the development of new HIV prevention strategies for men. PMID- 29584770 TI - Visualizing the Bayesian 2-test case: The effect of tree diagrams on medical decision making. AB - In medicine, diagnoses based on medical test results are probabilistic by nature. Unfortunately, cognitive illusions regarding the statistical meaning of test results are well documented among patients, medical students, and even physicians. There are two effective strategies that can foster insight into what is known as Bayesian reasoning situations: (1) translating the statistical information on the prevalence of a disease and the sensitivity and the false alarm rate of a specific test for that disease from probabilities into natural frequencies, and (2) illustrating the statistical information with tree diagrams, for instance, or with other pictorial representation. So far, such strategies have only been empirically tested in combination for "1-test cases", where one binary hypothesis ("disease" vs. "no disease") has to be diagnosed based on one binary test result ("positive" vs. "negative"). However, in reality, often more than one medical test is conducted to derive a diagnosis. In two studies, we examined a total of 388 medical students from the University of Regensburg (Germany) with medical "2-test scenarios". Each student had to work on two problems: diagnosing breast cancer with mammography and sonography test results, and diagnosing HIV infection with the ELISA and Western Blot tests. In Study 1 (N = 190 participants), we systematically varied the presentation of statistical information ("only textual information" vs. "only tree diagram" vs. "text and tree diagram in combination"), whereas in Study 2 (N = 198 participants), we varied the kinds of tree diagrams ("complete tree" vs. "highlighted tree" vs. "pruned tree"). All versions were implemented in probability format (including probability trees) and in natural frequency format (including frequency trees). We found that natural frequency trees, especially when the question-related branches were highlighted, improved performance, but that none of the corresponding probabilistic visualizations did. PMID- 29584771 TI - Interaction of microtubule depolymerizing agent indanocine with different human alphabeta tubulin isotypes. AB - Tubulin isotypes are known to regulate the stability and dynamics of microtubules, and are also involved in the development of resistance against microtubule-targeted cancer drugs. Indanocine, a potent microtubule depolymerizing agent, is highly active against multidrug-resistant (MDR) cancer cells without affecting normal cells. It is known to disrupt microtubule dynamics in cells and induce apoptotic cell death. Indanocine is reported to bind to tubulin at the colchicine site i.e. at the interface of alphabeta tubulin heterodimer. However, it's precise binding mode, involved molecular interactions and the binding affinities with different alphabeta-tubulin isotypes present in MDR cells are not well understood. Here, the binding affinities of human alphabeta-tubulin isotypes with indanocine were examined, employing the molecular modeling approach i.e. docking, molecular dynamics simulation and binding energy calculations. Multiple sequence analysis suggests that the amino acid sequences are different in the indanocine binding pockets of betaI, betaIIa, betaIII and betaVI isotypes. However, such differences are not observed in the amino acid sequences of betaIVa, betaIVb, and betaV tubulin isotypes at indanocine binding pockets. Docking and molecular dynamics simulation results show that indanocine prefers the interface binding pocket of alphabetaIIa, alphabetaIII, alphabetaIVb, alphabetaV, and alphabetaVI tubulin isotypes; whereas it is expelled from the interface binding pocket of alphabetaIVa and alphabetaI-tubulin isotypes. Further, binding free energy calculations show that alphabetaVI has the highest binding affinity and alphabetaI has the lowest binding affinity for indanocine among all beta-tubulin isotypes. The binding free energy decreases in the order of alphabetaVI > alphabetaIVb > alphabetaIIa > alphabetaIII > alphabetaV > alphabetaIVa > alphabetaI. Thus, our study provides a significant understanding of involved molecular interactions of indanocine with tubulin isotypes, which may help to design potent indanocine analogues for specific tubulin isotypes in MDR cells in future.

AB - Scrapie is a transmissible spongiform encephalopathy in sheep and an example of a disease that may be controlled through breeding for disease resistance. Member states of the European Union have introduced strategies for breeding against scrapie based on the selection of genetically resistant breeding rams. An ambitious strategy adopted in The Netherlands consisted of selecting resistant rams for breeding throughout both breeding and production sectors. Mathematical modelling of the effect of a breeding program on the spreading capacity of scrapie in a national flock is needed for making assessments on how long a breeding strategy needs to be maintained to achieve disease control. Here we describe such a model applied to the Dutch situation, with the use of data on the genetic content of the Dutch sheep population as well as on scrapie occurrence in this population. We show that the time needed for obtaining scrapie control depends crucially on two parameters measuring sheep population structure: the between-flock heterogeneity in genotype frequencies, and the heterogeneity of mixing (contact rates) between sheep flocks. Estimating the first parameter from Dutch genetic survey data and assuming scenario values for the second one, enables model prediction of the time needed to achieve scrapie control in The Netherlands.

AB - INTRODUCTION: Improving maternal health outcomes remains a priority in Low and Middle Income Countries. With the rapid proliferation of mobile health technologies, there is an increased interest in understanding how these technologies can effectively improve maternal health outcomes particularly maternal health seeking knowledge and behaviors. However, few studies present clear explanations of the program developers' rationale (theory of change) and contextual factors that could influence program outcomes. This mixed-methods study assesses Mobile for Mothers, a community health workers (CHW) utilized maternal mHealth intervention. We present the program developers' rationale and utilize it as a framework to guide our study that aimed to identify intervention related and contextual factors, which influence the observed outcomes of a CHW, utilized mHealth intervention. MATERIALS AND METHODS: Quantitative methods (a questionnaire with 740 women who received the intervention and survey of 57 CHWs who utilized the intervention) and qualitative methods (12 interviews and 4 group discussions with CHWs and 20 interviews and 5 group discussions with pregnant and lactating women and 15 interviews and 2 group discussions with men) were conducted. These were used to understand how the mHealth intervention was implemented and to gain insight into contextual factors that potentially influenced the observed intervention outcomes. RESULTS: Results were grouped following three categories: (1) perceptions and experiences of CHWs utilizing the mHealth technology; (2) CHW-related outcomes; and (3) contextual factors that influence maternal health-seeking behavior. The overall response of CHWs and community members to the intervention was positive. However, contextual factors like the relationship between the CHWs and their respective communities, the pregnant women's decision-making power and lack of access due to financial influenced the observed outcomes. CONCLUSION: Mobile health applications are promising interventions for improving the performance of CHWs and health-seeking behavior of pregnant women. However, the contextual factors play a crucial role in intervention outcomes and need to be explicated by program developers during intervention design and implementation.

AB - The aim of this study was to analyze the position of the lumbopelvic region and the muscle activation of erector spinae and biceps femoris muscles in a group of pregnant women in the third trimester. The hypothesis was that pregnancy-related biomechanical and morphological changes modify the position of the lumbopelvic region and the activation of extensor muscles. The position of the lumbar spine and pelvis in the sagittal plane, and the EMG activity of the erector spinae and biceps femoris muscles, were recorded during standing in 34 nulliparous and 34 pregnant women in the third trimester, and also two months after birth in the group of pregnant women. No significant differences in the position of the lumbar spine or pelvis between the group of pregnant women and nulliparous or postpartum were observed. A significant increase was observed in the EMG activity of the erector spinae (4.6% vs 2.4% and 2.1% in the nulliparous group and postpartum respectively) and the biceps femoris (3.4% vs 1.2% and 1.4%) in pregnant women compared to the other two groups (p <0.01). We conclude that pregnant women in the third trimester show no alterations in lumbopelvic position compared to nulliparous and postpartum women. However, there is an increase of the EMG activity of the trunk extensors. These results indicate that the extensor muscles of the trunk show, in static positions, adaptive responses to the increase of anterior loads during pregnancy.

The mechanism by which tuberculous infection becomes established in the eye is poorly understood. We have developed the zebrafish larva infected with Mycobacterium marinum as a model to study the early pathogenesis of ocular TB. We find that hematogenous bacterial seeding of the eye occurs despite a functional blood retinal barrier. Prototypical early granulomas form in response to bacteria in the eye. These granulomas involve the retinal vasculature and retinal pigment epithelium-choroid complex which are characteristic locations for human ocular TB. We find that peripheral blood monocytes are recruited to the nascent ocular granuloma further suggesting that the immune privileged nature of the eye is breached by this inflammatory focus.

AB - Analyzing extracellular vesicles (EVs) is an attractive approach to diagnosis of prostate diagnosis. However, existing methods of EVs isolation have low efficiency, purity, and long process time, and therefore have low diagnostic ability. To solve these the problems, a two-phase system is adapted to isolate EVs from a patient's urine. Urine from 20 prostate cancer (PCA) patients and 10 benign prostate hyperplasia patients was used to quantify the EVs-isolation ability of an aqueous two-phase system (ATPS) and to compare the diagnostic ability of ATPS with that of the conventional diagnosis method. An optimized ATPS isolates EVs with ~100% efficiency within ~30 min, with 14 times as high as achieved by ultracentrifugation. Afterward, PCR and ELISA are used to detect EVs derived from PCA cells in urine. The results demonstrate that diagnostic ability based on ATPS is better than other conventional diagnostic methods. ATPS can obtain a high quality and quantity of EVs from patients' urine. EVs contain cancer-related protein and genes, so these abundant sources enable diagnosis with high specificity and sensitivity. Therefore, ATPS is a useful tool to increase the specificity and sensitivity of diagnosis.

AB - Antennal sensory units in nymphs and adults of the spotted Lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoromorpha: Fulgoridae), an economically important plant pest, are studied with scanning electron microscopy. Sensilla trichodea / chaetica type recognition is based on their external morphology and ratio of their size to diameter. The flagellum Bourgoin's organ is a complex sensory unit with 2-3 internal sensilla coeloconica. During nymphal stages, the sensory surface available for a chemoreceptive function particularly increases with the number and size of sensilla placodea on the antennal pedicel. From first to fourth instar and to adult males and females, plate organ sensory surface is estimated to increase respectively by 33x, 68x and 125x (= 2.72 mm2 and 5.02 mm2 respectively for males and females). The most important increase (5x) occurs between second and third instar. In parallel, a distinctive pair of plate organs on the flagellum decreases in size from first to third instar, and disappears. Sexual dimorphism occurs in sensilla placodea in adults. Diversity, disparity and evolution of nymphal sensilla, and their sexual dimorphism in adults are discussed in the context of the species and planthopper behaviour. PMID- 29584778 TI - The enzymatic de-epithelialization technique determines denuded amniotic membrane integrity and viability of harvested epithelial cells. AB - The human amniotic membrane (HAM) is widely used for its wound healing effect in clinical practice, as a feeder for the cell cultivation, or a source of cells to be used in cell therapy. The aim of this study was to find effective and safe enzymatic HAM de-epithelialization method leading to harvesting of both denuded undamaged HAM and viable human amniotic epithelial cells (hAECs). The efficiency of de-epithelialization using TrypLE Express, trypsin/ ethylenediaminetetraacetic (EDTA), and thermolysin was monitored by hematoxylin and eosin staining and by the measurement of DNA concentration. The cell viability was determined by trypan blue staining. Scanning electron microscopy and immunodetection of collagen type IV and laminin alpha5 chain were used to check the basement membrane integrity. De-epithelialized hAECs were cultured and their stemness properties and proliferation potential was assessed after each passage. The HAM was successfully de-epithelialized using all three types of reagents, but morphological changes in basement membrane and stroma were observed after the thermolysin application. About 60% of cells remained viable using trypsin/EDTA, approximately 6% using TrypLE Express, and all cells were lethally damaged after thermolysin application. The hAECs isolated using trypsin/EDTA were successfully cultured up to the 5th passage with increasing proliferation potential and decreased stem cell markers expression (NANOG, SOX2) in prolonged cell culture. Trypsin/EDTA technique was the most efficient for obtaining both undamaged denuded HAM and viable hAECs for consequent culture. PMID- 29584779 TI - Oral administration of Pantoea agglomerans-derived lipopolysaccharide prevents development of atherosclerosis in high-fat diet-fed apoE-deficient mice via ameliorating hyperlipidemia, pro-inflammatory mediators and oxidative responses. AB - Pantoea agglomerans (P. agglomerans) is a Gram-negative bacterium that grows symbiotically with various edible plants, and the oral or sublingual administration of lipopolysaccharide derived from P. agglomerans (LPSp) have been suggested to contribute to prevention of immune-related diseases. Our previous study indicated that orally administered LPSp was shown to exhibit an LDL lowering effect in hyperlipidemic volunteers; however, a preventive effect of LPSp on atherosclerosis is unclear. The present study attempted to evaluate the anti-atherosclerotic effect by LPSp in a mouse model of high-fat diet (HFD) induced atherosclerosis. For 16 weeks, apoE-deficient mice were fed an HFD and received drinking water containing LPSp (0.3 or 1 mg/kg body weight/day). The results showed that the orally administered LPSp decreased body weight. A significant reduction in atherosclerotic plaque deposition was observed even with the lower dose of LPSp. The biochemical analyses showed that LPSp markedly improved glucose tolerance and reduced plasma LDL and oxidized LDL levels. In addition, LPSp significantly reduced the production of pro-inflammatory mediators including MCP-1 (in the plasma), TNF-alpha and IL-6 (in the colon), and decreased the oxidative burst activities in the peripheral blood sample. Taken together, these results suggest the possibility that oral administration of LPSp can effectively ameliorate HFD-induced hyperlipidemia and inflammatory/oxidative responses to prevent atherosclerosis and related metabolic disorders. PMID- 29584781 TI - Working memory, age and education: A lifespan fMRI study. AB - Ageing is associated with grey matter atrophy and changes in task-related neural activations. This study investigated the effects of age and education on neural activation during a spatial working memory task in 189 participants aged between 20-80 years old, whilst controlling for grey matter density. Age was related to linear decreases in neural activation in task activated areas, and this effect was no longer significant when adjusting for education or accuracy. Age was also related to cubic increases in neural activation in non-task related areas, such as the temporal gyrus, cuneus and cerebellum when adjusting for accuracy and education. These findings support previous lifespan datasets indicating linear age-related decreases in task activation, but non-linear increases in non-task related areas during episodic memory tasks. The findings also support past studies indicating education offers a form of cognitive reserve through providing a form of neural compensation and highlights the need to consider education in ageing studies. PMID- 29584782 TI - Genomic diversity of Taylorella equigenitalis introduced into the United States from 1978 to 2012. AB - Contagious equine metritis is a disease of worldwide concern in equids. The United States is considered to be free of the disease although sporadic outbreaks have occurred over the last few decades that were thought to be associated with the importation of horses. The objective of this study was to create finished, reference quality genomes that characterize the diversity of Taylorella equigenitalis isolates introduced into the USA, and identify their differences. Five isolates of T. equigenitalis associated with introductions into the USA from unique sources were sequenced using both short and long read chemistries allowing for complete assembly and annotation. These sequences were compared to previously published genomes as well as the short read sequences of the 200 isolates in the National Veterinary Services Laboratories' diagnostic repository to identify unique regions and genes, potential virulence factors, and characterize diversity. The 5 genomes varied in size by up to 100,000 base pairs, but averaged 1.68 megabases. The majority of that diversity in size can be explained by repeat regions and 4 main regions of difference, which ranged in size from 15,000 to 45,000 base pairs. The first region of difference contained mostly hypothetical proteins, the second contained the CRISPR, the third contained primarily hemagglutinin proteins, and the fourth contained primarily segments of a type IV secretion system. As expected and previously reported, little evidence of recombination was found within these genomes. Several additional areas of interest were also observed including a mechanism for streptomycin resistance and other virulence factors. A SNP distance comparison of the T. equigenitalis isolates and Mycobacterium tuberculosis complex (MTBC) showed that relatively, T. equigenitalis was a more diverse species than the entirety of MTBC. PMID- 29584784 TI - Statistical and Machine Learning forecasting methods: Concerns and ways forward. AB - Machine Learning (ML) methods have been proposed in the academic literature as alternatives to statistical ones for time series forecasting. Yet, scant evidence is available about their relative performance in terms of accuracy and computational requirements. The purpose of this paper is to evaluate such performance across multiple forecasting horizons using a large subset of 1045 monthly time series used in the M3 Competition. After comparing the post-sample accuracy of popular ML methods with that of eight traditional statistical ones, we found that the former are dominated across both accuracy measures used and for all forecasting horizons examined. Moreover, we observed that their computational requirements are considerably greater than those of statistical methods. The paper discusses the results, explains why the accuracy of ML models is below that of statistical ones and proposes some possible ways forward. The empirical results found in our research stress the need for objective and unbiased ways to test the performance of forecasting methods that can be achieved through sizable and open competitions allowing meaningful comparisons and definite conclusions. PMID- 29584783 TI - Regional Outcome Evaluation Program (P.Re.Val.E.): Reduction of inequality in access to effective health care in the Lazio region of Italy (2012-2015). AB - BACKGROUND: Inequalities in health among groups of various socio-economic status (as measured by education, occupation, and income) constitute one of the main challenges for public health. Since 2006, the Lazio Regional Outcome Evaluation Program (P.Re.Val.E.), presents a set of indicators of hospital performance based on quality standards driven by strong clinical recommendations, and measures the variation in the access to effective health care for different population groups and providers in the Lazio Region. One of the aims of the program was to compare population subgroups in order to promote equity in service provision. Since June 2013, a new management strategy has been put in place that assigned specific goals based on performance assessment to the chief executive officers of the hospitals. AIM: To evaluate whether, in recent years, there has been a reduction in the differential access to effective health care, among individuals with different educational levels. METHODS: We enrolled all patients discharged from both public and private hospitals of the Lazio region between 2012 and 2015, living in Lazio region. We analysed the proportion of patients with ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention within 90 minutes (primary PCI), the proportion of patients with hip fracture (HF) who underwent surgery within 2 days, and the proportion of women with primary C-section. We applied multivariate logistic regression models to assess the effect of educational level on health outcomes, adjusting for demographic characteristics and comorbidities that could affect the outcomes. For each year of the study period, we compared adjusted proportions of outcomes for the highest and the lowest level of education by using percentage differences. RESULTS: In the Lazio region, 44.6% of STEMI patients (N = 3,299) were treated with primary PCI, 54.4% of patients with hip fractures (N = 6,602) underwent surgery within 2 days, and 27.7% of women without a previous C-section (N = 34,718) delivered via C-section, in 2015. The corresponding proportions in 2012 were 27.8%, 31.3% and 31.5%, respectively. By comparing the adjusted proportions in patients with the highest education level (a university degree or higher) to those with the lowest level education level (None/Primary school), a decrease in the percentage difference was observed during the study period. In STEMI and delivery cohorts, the improvement of outcomes involved the least and the most educated patients, respectively, and the difference between the two educational levels was close to zero in 2015, whereas for hip patients, the improvement was more evident among the less educated patients. CONCLUSIONS: In the Lazio region, we observed a reduction in the differential access to effective heath care by educational level, in different clinical areas. Different factors might explain these results. On top of the public disclosure of outcome data, the management strategy applied in mid-2013 might have driven the overall improvement of the health system for the considered conditions, helping to achieve a fairer access to health. PMID- 29584785 TI - Relationships between anhedonia, suicidal ideation and suicide attempts in a large sample of physicians. AB - BACKGROUND: The relationships between anhedonia and suicidal ideation or suicide attempts were explored in a large sample of physicians using the interpersonal psychological theory of suicide. We tested two hypotheses: firstly, that there is a significant relationship between anhedonia and suicidality and, secondly, that anhedonia could mediate the relationships between suicidal ideation or suicide attempts and thwarted belongingness or perceived burdensomeness. METHODS: In a cross-sectional study, 557 physicians filled out several questionnaires measuring suicide risk, depression, using the abridged version of the Beck Depression Inventory (BDI-13), and demographic and job-related information. Ratings of anhedonia, perceived burdensomeness and thwarted belongingness were then extracted from the BDI-13 and the other questionnaires. RESULTS: Significant relationships were found between anhedonia and suicidal ideation or suicide attempts, even when significant variables or covariates were taken into account and, in particular, depressive symptoms. Mediation analyses showed significant partial or complete mediations, where anhedonia mediated the relationships between suicidal ideation (lifetime or recent) and perceived burdensomeness or thwarted belongingness. For suicide attempts, complete mediation was found only between anhedonia and thwarted belongingness. When the different components of anhedonia were taken into account, dissatisfaction-not the loss of interest or work inhibition-had significant relationships with suicidal ideation, whereas work inhibition had significant relationships with suicide attempts. CONCLUSIONS: Anhedonia and its component of dissatisfaction could be a risk factor for suicidal ideation and could mediate the relationship between suicidal ideation and perceived burdensomeness or thwarted belongingness in physicians. Dissatisfaction, in particular in the workplace, may be explored as a strong predictor of suicidal ideation in physicians. PMID- 29584786 TI - Chronic health conditions and school performance in first graders: A prospective cohort study. AB - OBJECTIVE: Children with chronic health conditions may perform poorer at school. Associations may be confounded by numerous social factors. We aimed to estimate the effects of a chronic health condition on overall school performance in first graders with an emphasis on rigorous adjustment for potential confounders. METHODS: A population-based cohort study was performed in the area of Mainz Bingen (Germany). In 2015 all preschoolers were approached and the presence of a chronic health condition was assessed by parental questionnaires and preschool health examination data. The identification of a chronic health condition was based on special health care needs and presence of a doctor's diagnosis out of 24 school-relevant diseases. At the end of the first school year, overall school performance was assessed by teachers and rated on a 5-item scale ranging from -10 to +10. RESULTS: Of 3683 children approached, 2003 were enrolled. Overall school performance was available for 1462 children (51% boys). Of these, 52% suffered from a chronic health condition. Compared to children without a chronic health condition, children with special health care needs (15%) performed worse at school (adjusted mean difference: -0.95, 95% CI: [-1.55; -0.35], P = 0.002). Children with a doctor's diagnosis but without special health care needs (37%) did not perform worse at school. The effect was further analysed considering the extent of special health care needed. CONCLUSIONS: Chronic health conditions affect overall school performance early in primary school. To identify academically at-risk children, a chronic health condition identification based on special health care needs may be used. PMID- 29584787 TI - Factors affecting walking ability in female patients with rheumatoid arthritis. AB - OBJECTIVE: To determine the factors associated with gait parameters in female patients with rheumatoid arthritis (RA). METHODS: The gait analysis was performed in a large cohort of RA patients, and three basic gait parameters (step length, cadence and gait speed) were calculated. Clinical and laboratory data were also collected. Factors associated with gait parameters were analyzed using multivariable linear regression in the three models with forced entry. Then, we divided those patients with Health Assessment Questionnaire disability index (HAQ) scores <= 0.5 into two groups according to their gait speed that were compared to identify the characteristics of patients with a good HAQ score but poor walking ability. RESULTS: A total of 318 female patients were analyzed. Knee extension strength had the strongest positive association with all three gait parameters (P < 0.0001), while methotrexate use was also positively associated with all three gait parameters (step length: P < 0.05, cadence: P < 0.05 in model 1 and 2; P < 0.01 in model 3, gait speed: P < 0.01). The disease activity score was negatively associated with step length and gait speed (step length, gait speed: P < 0.01 in model 1 and 2; P < 0.05 in model 3). 26% of patients with good HAQ scores showed slow gait speed. Patients with good HAQ scores and slow gait speed had higher disease activity scores (P < 0.05) and lower knee extension strength (P < 0.0001) than those with good HAQ scores and normal gait speed. CONCLUSIONS: High knee extension strength, low disease activity and administration of methotrexate were strongly associated with good walking ability in female patients with RA. And, even if patients showed good HAQ scores, about quarter of those patients had poor walking ability, and they showed higher disease activity, lower knee extension strength, compared to the patients with normal gait speed. PMID- 29584788 TI - IL-17A, IL-17RC polymorphisms and IL17 plasma levels in Tunisian patients with rheumatoid arthritis. AB - BACKGROUND: Interleukin-17 (IL-17), a cytokine mainly secreted by Th17 cells, seems to play a significant role in the pathogenesis of rheumatoid arthritis (RA). Functional genetic polymorphisms in IL-17 and its receptor genes can influence either qualitatively or quantitatively their functions. Therefore, we aimed to study the impact of IL17-A and IL17RC polymorphisms on plasma level of IL-17 and RA susceptibility and severity. METHODS: In this context, IL 17A*rs2275913 and IL-17RC*rs708567 polymorphisms were investigated together with the quantification of IL17 plasma level in 115 RA patients and 91 healthy control subjects matched in age, sex and ethnic origin. RESULTS: There were no statistically significant associations between IL-17A and IL-17RC studied polymorphisms and RA susceptibility. In contrast, IL-17A plasma levels were significantly higher in patients (55.07 pg/ml) comparatively to controls (4.75 pg/ml), p<10E-12. A ROC curve was used to evaluate the performance of plasma IL 17 in detecting RA. Given 100% specificity, the highest sensitivity of plasma IL 17A was 61.7% at a cut-off value of 18.25 pg/ml; p < 10E-21, CI = [0.849-0.939]. Analytic results showed that the IgM-rheumatoid factor and anti-CCP antibodies were significantly less frequent in patients with the IL-17RC*A/A genotype than those carrying *G/G and *G/A genotypes; p = 0.013 and p = 0.015, respectively. Otherwise, IL-17 plasma levels' analysis showed a significant association with the activity of RA (DAS28>=5.1 = 74.71 pg/ml vs. DAS28<5.1 = 11.96 pg/ml), p<10E 6. CONCLUSION: IL-17A*rs2275913 (G/A) and IL-17RC*rs708567 (G/A) polymorphisms did not seem to influence RA susceptibility in Tunisian population. This result agrees with those reported previously. Plasma IL-17A level seems to be predictive of severe RA occurrence. PMID- 29584789 TI - The effect of CAG repeats length on differences in hirsutism among healthy Israeli women of different ethnicities. AB - PURPOSE: Variations in the degree of hirsutism among women of different ethnic backgrounds may stem from multiple etiologies. Shorter length of the polymorphic CAG repeats of the androgen receptor (AR) gene may be associated with increased activity of the receptor leading to hirsutism. We hypothesized that there are ethnic differences in the degree of hirsutism that is unrelated to androgen levels among Israeli women, and that the CAG repeats length may contribute to these differences. Anti-androgenic therapies, such as spironolactone, could be suggested if a shorter CAG repeats length is found to affect the difference in the degree of hirsutism between the ethnic groups. METHODS: Healthy Israeli Jewish women aged 18-45 years of Ashkenazi and non-Ashkenazi origin were invited to participate. Hirsutism was assessed using the simplified Ferriman-Gallwey (sFG) score, and serum total testosterone levels were measured as well. The CAG repeats length was determined by PCR. Methylation-sensitive methods were used to detect the fractional activity of each allele, and the weighted mean was calculated for the CAG repeats length. RESULTS: One-hundred and eight women were recruited (49 Ashkenazi and 59 non-Ashkenazi). The Ashkenazi women had a significantly lower degree of hirsutism (P<0.01), lower mean BMI (P = 0.003), total testosterone levels (P = 0.017), and longer weighted bi-allelic CAG repeats mean (P = 0.015) compared to non-Ashkenazi women. For the group as a whole, there was a significant negative correlation between the number of CAG repeats in the AR gene and the sFG score, while the number of repeats was not related to testosterone levels. Stepwise logistic regression revealed that ethnic origin and the CAG repeats length were the strongest factors affecting hirsutism (P<0.001, P = 0.03, respectively). CONCLUSIONS: There is a significant difference in the degree of hirsutism between Ashkenazi and non-Ashkenazi women in Israel that is partially explained by CAG repeats length. PMID- 29584791 TI - Respiratory isolation for tuberculosis: the experience of Indigenous peoples on the Canadian prairies. AB - Setting: The Prairie provinces of Canada. Objective: To understand how Indigenous peoples with infectious pulmonary tuberculosis living in different community settings in the Prairie provinces of Canada experience respiratory isolation. Design: Using an exploratory qualitative approach, we interviewed participants living in urban centres, non-remote reserve settings and remote and isolated reserve settings. Results: Through qualitative content analysis of 48 interviews, we determined that participants experienced feelings of confinement regardless of the community setting in which they lived. Participants also experienced family and social disconnect, but the experience was more potent for the remote and isolated reserve participants, who were required to be flown out of their home communities to receive treatment, and for those urban centre and non-remote reserve participants who lacked social connections. The roles of past experiences with sanitoria and of family in providing social support are discussed. Conclusions: The conclusions of this study focus on examining isolation policies and improving the hospital isolation experience. PMID- 29584790 TI - Extreme umbilical cord lengths, cord knot and entanglement: Risk factors and risk of adverse outcomes, a population-based study. AB - OBJECTIVES: To determine risk factors for short and long umbilical cord, entanglement and knot. Explore their associated risks of adverse maternal and perinatal outcome, including risk of recurrence in a subsequent pregnancy. To provide population based gestational age and sex and parity specific reference ranges for cord length. DESIGN: Population based registry study. SETTING: Medical Birth Registry of Norway 1999-2013. POPULATION: All singleton births (gestational age>22weeks<45 weeks) (n = 856 300). METHODS: Descriptive statistics and odds ratios of risk factors for extreme cord length and adverse outcomes based on logistic regression adjusted for confounders. MAIN OUTCOME MEASURES: Short or long cord (<10th or >90th percentile), cord knot and entanglement, adverse pregnancy outcomes including perinatal and intrauterine death. RESULTS: Increasing parity, maternal height and body mass index, and diabetes were associated with increased risk of a long cord. Large placental and birth weight, and fetal male sex were factors for a long cord, which again was associated with a doubled risk of intrauterine and perinatal death, and increased risk of adverse neonatal outcome. Anomalous cord insertion, female sex, and a small placenta were associated with a short cord, which was associated with increased risk of fetal malformations, placental complications, caesarean delivery, non-cephalic presentation, perinatal and intrauterine death. At term, cord knot was associated with a quadrupled risk of perinatal death. The combination of a cord knot and entanglement had a more than additive effect to the association to perinatal death. There was a more than doubled risk of recurrence of a long or short cord, knot and entanglement in a subsequent pregnancy of the same woman. CONCLUSION: Cord length is influenced both by maternal and fetal factors, and there is increased risk of recurrence. Extreme cord length, entanglement and cord knot are associated with increased risk of adverse outcomes including perinatal death. We provide population based reference ranges for umbilical cord length. PMID- 29584792 TI - Risk factors for unfavourable treatment outcome among new smear-positive pulmonary tuberculosis cases in China. AB - Setting: Three projects of the Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB. Objectives: To assess unfavourable treatment outcomes (UTOs), including failure, died, loss to follow-up (LTFU), transferred out and unknown outcome, and to identify risk factors associated with UTOs. Design: This was a cross-sectional study using routine programme data. Results: Of 30 277 new smear-positive tuberculosis (TB) patients, 4261 (14.1%) had UTOs: 2048 (6.8%) LTFU, 1418 (4.7%) transferred out, 390 (1.3%) died, 340 (1.1%) failed and 65 (0.2%) had an unknown outcome. Risk factors for LTFU (including LTFU, transfer out and unknown outcome) were residing in Anhui, age > 55 years, service delay > 10 days, patient delay < 30 days, directly observed treatment (DOT) provided by a family member or others and unknown DOT provider. The outcome of 'died' was associated with residing in Shaanxi, age > 55 years, male sex, patient delay > 30 days and unknown DOT provider. 'Failed' was associated with having unlimited access to health services, patient delay of >30 days and unknown DOT provider. Conclusion: This study highlights the predominance of lost patients among UTOs. Patients with family members or other non-medical DOT providers or unknown DOT providers had a high risk of a UTO. There is an urgent need to address these service-related factors. PMID- 29584793 TI - Characteristics and management of presumptive tuberculosis in public health facilities in Malawi, 2014-2016. AB - Setting: Public health facilities providing tuberculosis (TB) and human immunodeficiency virus (HIV) services in Malawi. Objectives: Using routinely collected health service delivery data to describe trends in HIV ascertainment and use of the Xpert(r) MTB/RIF assay to diagnose TB among HIV-positive presumptive TB cases. Design: This was an implementation study of presumptive TB cases who sought care from 21 facilities between April 2014 and June 2016. Descriptive statistics were used to summarise patient, facility and service level characteristics. Results: Of 28 567 presumptive TB cases analysed, 23 198 (81%) had known HIV status. The proportion of ascertained HIV status in presumptive TB cases increased over the study period. HIV prevalence was 49%, with 73% of HIV positive presumptive TB cases on antiretroviral therapy. Access to Xpert ranged between 37% and 63% per quarter among HIV-positive presumptive TB patients with smear-negative sputum results. Of 7829 patients with documented Xpert results, 68% were HIV-positive. Conclusion: After the introduction of registers with HIV related variables, HIV ascertainment among presumptive TB cases increased over time. Access to Xpert was suboptimal among HIV-positive presumptive TB cases. Further collaboration between national TB and HIV programmes may facilitate increased use of Xpert for HIV-positive patients with presumptive TB who seek care in public health facilities. PMID- 29584794 TI - Occupational tuberculosis in South Africa: are health care workers adequately protected? AB - Setting: A provincial tertiary hospital in Gauteng province, South Africa, with a high burden of tuberculosis (TB) patients and high risk of TB exposure among health care workers (HCWs). Objective: To determine HCWs' adherence to recommended TB infection prevention and control practices, TB training and access to health services and HCW TB rates. Design: Interviews with 285 HCWs using a structured questionnaire as part of a large, international mixed-methods study. Results: Despite 10 HCWs (including seven support HCWs) acquiring clinical TB during their period of employment, 62.8% of interviewees were unaware of the hospital's TB management protocol. Receipt of training was low (34.5% of all HCWs and <5% of support HCWs trained on TB transmission; 27.5% of nurses trained on respirator use), as was use of respiratory protection (44.5% of HCWs trained on managing TB patients). Support HCWs were over 36 times more likely to use respiratory protection if trained; nurses who were trained were approximately 40 times more likely to use respirators if they were readily available. Conclusion: Improved coordination and uptake of TB infection prevention training is urgently needed, especially for non-clinical HCWs in settings of regular exposure to TB patients. Adequate supplies of appropriate respiratory protection must be made available. PMID- 29584795 TI - Sensitivity, completeness and agreement of the tuberculosis electronic system in Ho Chi Minh City, Viet Nam. AB - Setting: Since 2011, tuberculosis (TB) clinics in Ho Chi Minh City (HCMC), Viet Nam, have been entering data from a paper-based TB treatment register into an electronic database known as VITIMES (Viet Nam TB Information Management Electronic System), which is currently used in parallel with the paper system. Objective: To evaluate the sensitivity, completeness and agreement of data in VITIMES with that of paper-based registers among TB patients co-infected with the human immunodeficiency virus (HIV) being treated for TB in HCMC. Design: This was a retrospective data review of all TB-HIV patients receiving anti-tuberculosis treatment in each of the 24 district TB clinics in HCMC in 2013. Data were abstracted from the paper-based TB treatment registers at district level and extracted electronically at the provincial level. Records were matched based on name, age and address. The sensitivity, completeness and agreement of the electronic data were compared with data from the paper system. Results: The findings showed that the electronic system had high sensitivity (99.2%), high completeness (87-99%) and high agreement (kappa 0.78-0.97) for all variables. Conclusion: The results of this study suggest that data are being correctly entered into VITIMES and that patient data can be directly entered into VITIMES instead of having a parallel, paper-based system. PMID- 29584796 TI - Should sputum-negative presumptive TB patients be actively followed to identify missing cases in India? AB - Setting: Sputum smear microscopy, the primary diagnostic tool used for diagnosis of tuberculosis (TB) in India's Revised National TB Control Programme (RNTCP), has low sensitivity, resulting in a significant number of TB cases reported as sputum-negative. As the revised guidelines pose challenges in implementation, sputum-negative presumptive TB (SNPT) patients are subjected to 2 weeks of antibiotics, followed by chest X-ray (CXR), resulting in significant loss to care among these cases. Objective: To determine whether reducing delays in CXR would yield additional TB cases and reduce initial loss to follow-up for diagnosis among SNPT cases. Methods: In an ongoing intervention in five districts of Maharashtra, SNPT patients were offered upfront CXR. Results: Of 119 male and 116 female SNPT patients with a mean age of 45 years who were tested by CXR, 32 (14%) were reported with CXR suggestive of TB. Administering upfront CXR in SNPT patients yielded twice as many additional cases, doubling the proportion of cases detected among all those tested as against administering CXR 2 weeks after smear examination. Conclusion: Our interventional study showed that the yield of TB cases was significantly greater when upfront CXR examination was undertaken without waiting for a 2-week antibiotic trial. PMID- 29584797 TI - What drives 'first-time testers' to test for HIV at community-based HIV testing services? AB - Drivers of and barriers to testing are not well understood for those who have never been tested previously and now self-initiate at a community-based human immuno-deficiency virus (HIV) testing service (CB-HTS). This descriptive study enrolled 229 first-time testers. Participants completed an electronic questionnaire. The majority reported fear and (non) accessibility of HTS as barriers to testing (40% and 24%, respectively). Wanting 'to know my status' and the immediate opportunity to test were reported as drivers of testing (41% and 35%, respectively). Addressing fear of testing and providing an easily accessible opportunity to test may go some way to encouraging those previously untested individuals to test. PMID- 29584798 TI - Access to human immunodeficiency virus testing services in Cape Town, South Africa: a user perspective. AB - Objective: To compare the availability, affordability and acceptability of two non-governmental organisation (NGO) led human immunodeficiency virus (HIV) testing service (HTS) modalities (mobile and stand-alone) with HTS at a public primary health care facility. Methods: Adult participants who self-referred for HIV testing were enrolled as they exited the HTS modalities. Data collection using an electronic questionnaire took place between November 2014 and February 2015. Logistic regression analysis was used to assess differences in the participants' demographic characteristics and the availability, affordability and acceptability of HTS between modalities. Results: There were 130 participants included in the study. Irrespective of modality, most participants walked to the service provider, had a travel time of <30 min and reported no costs. Participants were less likely to report waiting times of ?30 min compared to <15 min at the mobile modality compared to the public facility (aOR < 0.001, 95%CI < 0.001-0.03). Conclusion: Irrespective of modality, HIV testing services were available and affordable in our study. Waiting times were significantly higher at the public facility compared to the NGO modalities. As South Africa moves toward achieving the first UNAIDS target, it is essential not only to make HTS available and affordable, but also to ensure that these services are acceptable, especially to those who have never been tested before. PMID- 29584799 TI - Enhancing tuberculosis patient detection and care through community volunteers in the urban poor, The Philippines. AB - Setting: The Research Institute of Tuberculosis/Japan Anti-Tuberculosis Association Philippines is a local non-governmental organisation (NGO) established in 2008 to improve access to tuberculosis (TB) services. Community health volunteers (CHVs) from NGO referring facilities were engaged to assist in local TB control activities. Objective: To describe the activities of the CHVs and the barriers experienced by patients with presumptive TB in seeking health care to treatment as documented on a master list, and to identify the CHVs' challenges in community TB care implementation. Design: This was a retrospective evaluation with a non-experimental design reviewing the presumptive TB master list and TB reports and conducting a free discussion session (FDS) in 2012. Results: Of the 78% (281/362) of referred presumptive TB patients who accessed a DOTS facility, 69% (194/281) underwent a diagnostic examination and 42% (81/194) were diagnosed with active TB. Of the 93% (75/81) initiated on treatment, 92% (69/75) were successfully treated. The CHVs contributed approximately 3% (75/2534) to the total TB cases diagnosed at the DOTS facilities. In the FDS, barriers evoked in seeking health care for treatment were transfer of residence and lack of interest in seeking a consultation. In 2012, the CHV attrition rate was 55% (80/145). Conclusion: The CHVs assisted in enhancing access to TB care and case detection. Sustainability of the CHVs' efforts should be explored to retain them in the programme. PMID- 29584800 TI - The sixth vital sign: HIV status assessment and severe illness triage in Uganda. AB - Setting: Four in-patient health facilities in western Uganda. Objective: To determine the impact of an innovative multi-modal quality improvement program on human immunodeficiency virus (HIV) status assessment and the impact of HIV status on severe illness conditions and mortality. Design: This was a staggered, pre post quasi-experimental study designed to assess a multi-modal intervention (collaborative improvement meetings, audit and feedback, clinical mentoring) for improving quality of care following formal training in the management of severe illness in low-income settings. Results: From August 2014 to May 2015, 5759 patients were hospitalized, of whom 2451 (42.6%) had their HIV status assessed; 395 (16.1%) were HIV-infected. HIV-infected patients were significantly more likely to meet criteria for shock (27.5% vs. 15.1%, risk ratio [RR] 1.8, 95% confidence interval [CI] 1.7-1.9, P < 0.001) and severe respiratory distress (6.7% vs. 4.3%, RR 1.5, 95%CI 1.2-2.0, P < 0.001), and were significantly more likely to die in hospital (12.0% vs. 2.9%, RR 4.1, 95%CI 3.2-5.4, P < 0.001). There was no evidence of improved HIV status assessment during the intervention period (36.5% vs. 44.8%, +8.3%, 95%CI -8.3 to 24.8, P = 0.33). Conclusions: Hospitalized HIV-infected patients in western Uganda are at high risk for severe illness and death. Novel quality improvement strategies are needed to enhance hospital-based HIV testing in high-burden settings. PMID- 29584801 TI - Immunochip Meta-Analysis of Inflammatory Bowel Disease Identifies Three Novel Loci and Four Novel Associations in Previously Reported Loci. AB - Background and Aims: Recent meta-analysis of genome-wide association studies have identified over 241 inflammatory bowel disease susceptibility loci. However, the known variants only account for a fraction of inflammatory bowel disease heritability. To identify additional susceptibility loci, we performed a trans ethnic meta-analysis as well as an Asian-specific meta-analysis, using all published Immunochip association results of inflammatory bowel disease. Methods: An inverse-variance fixed-effects meta-analysis was carried out across Korean and East Asian Immunochip datasets of 4156 cases and 4904 controls [Asian ancestry]. A trans-ethnic meta-analysis of inflammatory bowel disease was performed together with the European datasets of 38 155 cases and 48 485 controls genotyped on the immunochip using a Bayesian approach, Meta-Analysis of Trans-ethnic Association studies [MANTRA]. Results: We identified seven novel associations, including three novel susceptibility loci at MYO10-BASP1, PPP2R3C/KIAA0391/PSMA6/NFKB1A and LRRK1 as well as four novel secondary associations within previously known loci at NCF4, TSPAN32, CIITA and VANGL2. The new loci further implicate alterations in B cell biology in Crohn's disease pathogenesis. The effects of five loci were universal across European and Asian ancestries, whereas the NCF4 and CIITA loci showed significant heterogeneity between European and East Asian populations. In addition, 103 previously known IBD loci showed supporting evidence of association with nominal significance [p < 0.05] in Asians. Conclusions: Our findings of new loci not previously associated with IBD support the importance of studying inflammatory bowel disease genetics in diverse populations.

PMID- 29584803 TI - Involvement of acid-sensing ion channel 1a in gastric carcinoma cell migration and invasion. AB - Acidic microenvironment, particularly acid-sensing ion channel 1a (ASIC1a), has been reported to promote carcinoma cell proliferation as well as migration. In this study, we explored the effect of ASIC1a on migration and invasion of gastric carcinoma (GC). ASIC1a expression levels were examined in paired GC and adjacent normal tissues from 16 patients by immunohistochemistry. Reverse transcription real-time PCR and immunoblotting were conducted to assess the ASIC1a expression levels in the GC cell line AGS after transfection with ASIC1a small hairpin RNA (shRNA). Wound healing and transwell invasion assays were utilized to detect metastasis and invasion following ASIC1a silencing. Tumor formation was used to detect the role of ASIC1a in tumorigenicity in vivo. It was found that ASIC1a expression level was significantly higher in GC tissues showing postoperative metastasis compared with non-metastasis and non-tumor tissues. Moreover, silencing of ASIC1a with shRNA significantly down-regulated ASIC1a expression and reduced GC cell migration and invasion. A moderately acidic extracellular environment inhibited GC cell viability. Furthermore, ASIC1a shRNA caused inhibition of tumorigenicity in vivo. Our study is the first report of attenuating the malignant phenotype of GC in vitro and in vivo by suppressing ASIC1a, and suggests a novel approach to study the relationship between ASICs and GC cell migration and invasion. PMID- 29584805 TI - A Ten Year Immunopersistence Study of Hepatitis E Antibodies in Rural Bangladesh. AB - Hepatitis E virus (HEV) is a major cause of acute, viral hepatitis in Southeast Asia. Several studies have suggested that antibody persistence after HEV infection may be transient, possibly increasing the risk of re-infection and contributing to the frequency of outbreaks in HEV endemic regions. The specific conditions under which antibodies to HEV are lost, or "sero-reversion" occurs, are poorly understood. Here, one hundred participants from population-based studies in rural Bangladesh were revisited in 2015, ten years after a documented HEV infection to examine long-term antibody persistence. Twenty percent (95% confidence interval: 12.0, 28.0) no longer had detectable antibodies at follow up, suggesting that antibodies generally persist for at least a decade after infection in rural Bangladesh. Those who were seronegative at follow-up were generally younger at infection than those who remained positive (14.4 years versus 33.6 years, P > 0.0001). This age-dependent antibody loss could partially explain cross-sectional sero-prevalence data from South East Asia where children have reportedly low antibody prevalence. The results of this study provide new insight into the immunological persistence of HEV infection in a micronutrient deficient rural population of South Asia, highlighting the importance of age at infection in the ability to produce long-lasting antibodies against HEV. PMID- 29584802 TI - Perturbed autophagy and DNA repair converge to promote neurodegeneration in amyotrophic lateral sclerosis and dementia. AB - Maintaining genomic stability constitutes a major challenge facing cells. DNA breaks can arise from direct oxidative damage to the DNA backbone, the inappropriate activities of endogenous enzymes such as DNA topoisomerases, or due to transcriptionally-derived RNA/DNA hybrids (R-loops). The progressive accumulation of DNA breaks has been linked to several neurological disorders. Recently, however, several independent studies have implicated nuclear and mitochondrial genomic instability, perturbed co-transcriptional processing, and impaired cellular clearance pathways as causal and intertwined mechanisms underpinning neurodegeneration. Here, we discuss this emerging paradigm in the context of amyotrophic lateral sclerosis and frontotemporal dementia, and outline how this knowledge paves the way to novel therapeutic interventions. PMID- 29584806 TI - Placental Weight and Risk of Cryptorchidism and Hypospadias in the Collaborative Perinatal Project. AB - Cryptorchidism and hypospadias are the most common congenital anomalies of the genitourinary tract in males, but their etiology remains unclear. Placental insufficiency has been suggested to be linked to both conditions. Placental weight is a commonly used proxy measure for placental insufficiency; thus, we examined placental weight and other placental characteristics in relation to cryptorchidism and hypospadias in the Collaborative Perinatal Project, a US mother-child cohort study. Pregnant women were recruited between 1959 and 1965. The analysis contrasted boys with cryptorchidism (n = 413) and boys with hypospadias (n = 145) with boys without cryptorchidism (n = 23,799) and boys without hypospadias (n = 22,326). Odds ratios and 95% confidence intervals were calculated using unconditional logistic regression. In categorical analyses in which the middle tertile was the referent, cryptorchidism was inversely associated with placental weight (odds ratio = 0.66, 95% confidence interval: 0.46, 0.95) among white boys and positively associated with the lowest tertile of placental weight among black boys (odds ratio = 1.70, 95% confidence interval: 1.11, 2.59). We conclude that lower placental weight may be related to risk of cryptorchidism. Further investigation of placental functioning may offer insights into the etiology of cryptorchidism. PMID- 29584807 TI - Pain assessment in the older population: what the literature says. AB - Assessment of pain in the older adult presents a number of challenges, especially related to communication. This commentary summarises the revised evidence-based Guidelines on the Assessment of Pain in Older Adults which have been developed by the British Pain Society and British Geriatrics Society. The guideline summarises the pain assessment tools that have been developed and validated for use in the older population. Recommendations are made for use of specific tools in older people and in those with dementia. The need for education and training of health care professionals is emphasised. Gaps in the evidence are identified as subjects for future research. It is hoped that the guideline will improve recognition of pain in older people, and help to drive the future research agenda. PMID- 29584808 TI - Urocortin-2 improves right ventricular function and attenuates pulmonary arterial hypertension. AB - Aims: Pulmonary arterial hypertension (PAH) is a devastating disease and treatment options are limited. Urocortin-2 (Ucn-2) has shown promising therapeutic effects in experimental and clinical left ventricular heart failure (HF). Our aim was to analyse the expression of Ucn-2 in human and experimental PAH, and to investigate the effects of human Ucn-2 (hUcn-2) administration in rats with monocrotaline (MCT)-induced pulmonary hypertension (PH). Methods and results: Tissue samples were collected from patients with and without PAH and from rats with MCT-induced PH. hUcn-2 (5 MUg/kg, bi-daily, i.p., for 10 days) or vehicle was administered to male wistar rats subjected to MCT injection or to pulmonary artery banding (PAB) to induce right ventricular (RV) overload without PAH. Expression of Ucn-2 and its receptor was increased in the RV of patients and rats with PAH. hUcn-2 treatment reduced PAH in MCT rats, resulting in decreased morbidity, improved exercise capacity and attenuated pulmonary arterial and RV remodelling and dysfunction. Additionally, RV gene expression of hypertrophy and failure signalling pathways were attenuated. hUcn-2 treatment also attenuated PAB induced RV hypertrophy. Conclusions: Ucn-2 levels are altered in human and experimental PAH. hUcn-2 treatment attenuates PAH and RV dysfunction in MCT induced PH, has direct anti-remodelling effects on the pressure-overloaded RV, and improves pulmonary vascular function. PMID- 29584809 TI - Floral morphology and morphogenesis in Camptotheca (Nyssaceae), and its systematic significance. AB - Background and Aims: Camptotheca is endemic to China and there are limited data about the breeding system and morphogenesis of the flowers. Camptotheca is thought to be related to Nyssa and Davidia in Nyssaceae, which has sometimes been included in Cornaceae. However, molecular phylogenetic studies confirmed the inclusion of Camptotheca in Nyssaceae and its exclusion from Cornaceae. The aim of this study was to reveal developmental features of the inflorescence and flowers in Camptotheca to compare with related taxa in Cornales. Methods: Inflorescences and flowers of Camptotheca acuminata at all developmental stages were collected and studied with a scanning electron microscope and stereo microscope. Key Results: Camptotheca has botryoids which are composed of several capitate floral units (FUs) that are initiated acropetally. On each FU, flowers are grouped in dyads that are initiated acropetally. All floral organs are initiated centripetally. Calyx lobes are restricted to five teeth. The hypanthium, with five toothed calyx lobes, is adnate to the ovary. The five petals are free and valvate. Ten stamens are inserted in two whorls around the central depression, in which the style is immersed. Three carpels are initiated independently but the ovary is syncarpous and unilocular. The ovule is unitegmic and heterotropous. Inflorescences are functionally andromonoecious varying with the position of the FUs on the inflorescence system. Flowers on the upper FU often have robust styles and fully developed ovules. Flowers on the lower FU have undeveloped styles and aborted ovules, and the flowers on the middle FU are transitional. Conclusions: Camptotheca possesses several traits that unify it with Nyssa, Mastixia and Diplopanax. Inflorescence and floral characters support a close relationship with Nyssaceae and Mastixiaceae but a distant relationship with Cornus. Our results corroborate molecular inferences and support a separate family Nyssaceae. PMID- 29584810 TI - Identification of miR-9-5p as direct regulator of ABCA1 and HDL-driven reverse cholesterol transport in circulating CD14+ cells of patients with metabolic syndrome. AB - Aims: Metabolic syndrome (MS) is a cluster of cardio-metabolic risk factors associated with atherosclerosis and low-grade inflammation. Using unbiased expression screenings in peripheral blood mononuclear cells, we depict here a novel expression chart of 678 genes and 84 microRNAs (miRNAs) controlling inflammatory, immune and metabolic responses. In order to further elucidate the link between inflammation and the HDL cholesterol pathway in MS, we focussed on the regulation of the ATP-binding cassette transporter A1 (ABCA1), a key player in cholesterol efflux (CE). Methods and results: ABCA1 mRNA levels are suppressed in CD14+ cells of MS patients and are negatively correlated to body mass index (BMI), insulin-resistance (HOMA-IR) and cardiovascular risk, and positively to HDL cholesterol and CE. miRNA target in silico prediction identified a putative modulatory role of ABCA1 for the nuclear factor kappa-light-chain-enhancer of activated B cell (NF-kappaB) target miR-9-5p, whose expression pattern was up regulated in CD14+ cells of MS patients, positively correlated to BMI, HOMA-IR, and triglycerides, and negatively to ABCA1 mRNA levels, HDL cholesterol and CE. Ectopic gain and loss of miR-9-5p function in macrophages modulated ABCA1 mRNA and protein levels, ABCA1 miRNA 3'-untranslated region target sequence reporter assay, and CE into HDL, thus confirming ABCA1 as a target of miR-9-5p. Conclusions: We identified the NF-kappaB target miR-9-5p as a negative regulator of ABCA1 adding a novel target pathway in the relationship between inflammation and HDL-driven reverse cholesterol transport for prevention or treatment of atherosclerosis in MS. PMID- 29584811 TI - Learned protein embeddings for machine learning. AB - Motivation: Machine-learning models trained on protein sequences and their measured functions can infer biological properties of unseen sequences without requiring an understanding of the underlying physical or biological mechanisms. Such models enable the prediction and discovery of sequences with optimal properties. Machine-learning models generally require that their inputs be vectors, and the conversion from a protein sequence to a vector representation affects the model's ability to learn. We propose to learn embedded representations of protein sequences that take advantage of the vast quantity of unmeasured protein sequence data available. These embeddings are low-dimensional and can greatly simplify downstream modeling. Results: The predictive power of Gaussian process models trained using embeddings is comparable to those trained on existing representations, which suggests that embeddings enable accurate predictions despite having orders of magnitude fewer dimensions. Moreover, embeddings are simpler to obtain because they do not require alignments, structural data, or selection of informative amino-acid properties. Visualizing the embedding vectors shows meaningful relationships between the embedded proteins are captured. Availability and implementation: The embedding vectors and code to reproduce the results are available at https://github.com/fhalab/embeddings_reproduction/.

PMID- 29584812 TI - Landmark Models for Optimizing the Use of Repeated Measurements of Risk Factors in Electronic Health Records to Predict Future Disease Risk. AB - The benefits of using electronic health records (EHRs) for disease risk screening and personalized health-care decisions are being increasingly recognized. Here we present a computationally feasible statistical approach with which to address the methodological challenges involved in utilizing historical repeat measures of multiple risk factors recorded in EHRs to systematically identify patients at high risk of future disease. The approach is principally based on a 2-stage dynamic landmark model. The first stage estimates current risk factor values from all available historical repeat risk factor measurements via landmark-age specific multivariate linear mixed-effects models with correlated random intercepts, which account for sporadically recorded repeat measures, unobserved data, and measurement errors. The second stage predicts future disease risk from a sex-stratified Cox proportional hazards model, with estimated current risk factor values from the first stage. We exemplify these methods by developing and validating a dynamic 10-year cardiovascular disease risk prediction model using primary-care EHRs for age, diabetes status, hypertension treatment, smoking status, systolic blood pressure, total cholesterol, and high-density lipoprotein cholesterol in 41,373 persons from 10 primary-care practices in England and Wales contributing to The Health Improvement Network (1997-2016). Using cross validation, the model was well-calibrated (Brier score = 0.041, 95% confidence interval: 0.039, 0.042) and had good discrimination (C-index = 0.768, 95% confidence interval: 0.759, 0.777). PMID- 29584813 TI - Yoga-based exercise improves health-related quality of life and mental well-being in older people: a systematic review of randomised controlled trials. AB - Objective: health-related quality of life (HRQOL) and mental well-being are associated with healthy ageing. Physical activity positively impacts both HRQOL and mental well-being. Yoga is a physical activity that can be modified to suits the needs of older people and is growing in popularity. We conducted a systematic review with meta-analysis to determine the impact of yoga-based exercise on HRQOL and mental well-being in people aged 60+. Methods: searches were conducted for relevant trials in the following electronic databases; MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Allied and Complementary Medicine Database, PsycINFO and the Physiotherapy Evidence Database (PEDro) from inception to January 2017. Trials that evaluated the effect of physical yoga on HRQOL and/or on mental well-being in people aged 60+ years were included. Data on HRQOL and mental well-being were extracted. Standardised mean differences and 95% confidence intervals (CI) were calculated using random effects models. Methodological quality of trials was assessed using the PEDro scale. Results: twelve trials of high methodological quality (mean PEDro score 6.1), totalling 752 participants, were identified and provided data for the meta-analysis. Yoga produced a medium effect on HRQOL (Hedges' g = 0.51, 95% CI 0.25-0.76, 12 trials) and a small effect on mental well-being (Hedges' g = 0.38, 95% CI 0.15-0.62, 12 trials). Conclusion: yoga interventions resulted in small to moderate improvements in both HRQOL and mental well-being in people aged 60+ years. Further, research is needed to determine the optimal dose of yoga to maximise health impact. PROSPERO registration number: (CRD42016052458). PMID- 29584816 TI - Erratum. PMID- 29584815 TI - Erratum.

AB - Multistate cure models are multistate models in which transitions into one or more of the states cannot occur for a fraction of the population. In the study of cancer, multistate cure models can be used to identify factors related to the rate of cancer recurrence, the rate of death before and after recurrence, and the probability of being cured by initial treatment. However, the previous method for fitting multistate cure models requires substantial custom programming, making these valuable models less accessible to analysts. In this article, we present an Expectation-Maximization (EM) algorithm for fitting the multistate cure model using maximum likelihood. The proposed algorithm makes use of a weighted likelihood representation allowing it to be easily implemented with standard software and can incorporate either parametric or non-parametric baseline hazards for the state transition rates. A common complicating feature in cancer studies is that the follow-up times for recurrence and death may differ. Additionally, we may have missingness in the covariates. We propose a Monte Carlo EM (MCEM) algorithm for fitting the multistate cure model in the presence of covariate missingness and/or unequal follow-up of the two outcomes, we describe a novel approach for obtaining standard errors, and we provide some software. Simulations demonstrate good algorithmic performance as long as the modeling assumptions are sufficiently restrictive. We apply the proposed algorithm to a study of recurrence and death in patients with head and neck cancer. PMID- 29584819 TI - Loss of AZIN2 splice variant facilitates endogenous cardiac regeneration. AB - Aims: Long noncoding RNAs (lncRNAs) are critical regulators of cardiovascular lineage commitment and heart wall development, but their roles in regulating endogenous cardiac regeneration are unclear. The present study investigated the role of human-derived lncRNA in regulating endogenous cardiac regeneration as well as the underlying mechanisms. Methods and results: We compared RNA sequencing data from human foetal and adult hearts and identified a novel lncRNA that was upregulated in adult hearts (Genesymbol NONHSAG000971/NONHSAT002258 or ENST00000497710.5), which was a splice variant of the AZIN2 gene (AZIN2-sv). We used quantitative PCR to confirm the increased expression of AZIN2-sv in adult rat hearts. Coexpression network analysis indicated that AZIN2-sv could regulate proliferation. Loss- and gain-of-function approaches demonstrated that AZIN2-sv negatively regulated endogenous cardiomyocyte proliferation in vitro and in vivo. Knockdown of AZIN2-sv attenuated ventricular remodelling and improved cardiac function after myocardial infarction. Phosphatase and tensin homolog (PTEN) was identified as a target of AZIN2-sv, their direct binding increased PTEN stability. Furthermore, AZIN2-sv acted as a microRNA-214 sponge to release PTEN, which blocked activation of the PI3 kinase/Akt pathway to inhibit cardiomyocyte proliferation. Conclusions: The newly discovered AZIN2-sv suppressed endogenous cardiac regeneration by targeting the PTEN/Akt pathway. Thus, AZIN2-sv may be a novel therapeutic target for preventing and treating heart failure. PMID- 29584822 TI - Table and Figure Errors. PMID- 29584821 TI - Papillary muscles contribute significantly more to left ventricular work in dilated hearts. AB - Aims: Left ventricular (LV) dilatation results in increased sphericity and affects position and orientation of papillary muscles (PMs), which may influence their performed work. The aim of this study was to assess the contribution of PM to LV function and its changes with dilatation. Methods and results: Fifteen sheep were investigated. Ten animals were subjected to 8 weeks of rapid (180 bpm) pacing, inducing LV dilatation. Five animals served as controls. High-resolution gated computed tomography was performed to assess LV volumes, left ventricular ejection fraction (LVEF), global longitudinal strain (GLS), sphericity index, and PM angle, width and fractional shortening. 18F-fluorodeoxyglucose positron emission tomography (PET) was used to measure glucose metabolism as surrogate of regional myocardial work. Spatial resolution of PET images was maximized by electrocardiogram- and respiratory-gating. 18F-fluorodeoxyglucose uptake was measured in PM and compared with remaining left ventricular myocardium (MYO) to obtain a PM/MYO ratio. Animals with dilated heart had a more spherical left ventricle, with reduced LVEF (P < 0.0001) and GLS (P < 0.0001). In dilated hearts, PET analysis revealed a higher contribution of both PM to LV myocardial work (P < 0.0001); and PM angle towards LV wall correlated with PM work, together with PM width and the LV sphericity index. Sphericity index and posterior PM angle were strongest determinants of posterior PM/MYO ratio (R2 = 0.754; P < 0.0001), while anterior PM/MYO was mostly determined by sphericity index and the PM width (R2 = 0.805; P < 0.0001). Conclusion: In dilated hearts, PM contribute relatively more to LV myocardial work. We hypothesize that this is caused by the more cross-sectional orientation of the subvalvular apparatus, which leads to a higher stress on the PM compared with the spherical LV walls. The reduced cross sectional area of the PM may further explain their increased stress.

PMID- 29584843 TI - Trends and Patterns of Differences in Infectious Disease Mortality Among US Counties, 1980-2014. AB - Importance: Infectious diseases are mostly preventable but still pose a public health threat in the United States, where estimates of infectious diseases mortality are not available at the county level. Objective: To estimate age standardized mortality rates and trends by county from 1980 to 2014 from lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis. Design and Setting: This study used deidentified death records from the National Center for Health Statistics (NCHS) and population counts from the US Census Bureau, NCHS, and the Human Mortality Database. Validated small-area estimation models were applied to these data to estimate county-level infectious disease mortality rates. Exposures: County of residence. Main Outcomes and Measures: Age-standardized mortality rates of lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis by county, year, and sex. Results: Between 1980 and 2014, there were 4 081 546 deaths due to infectious diseases recorded in the United States. In 2014, a total of 113 650 (95% uncertainty interval [UI], 108 764-117 942) deaths or a rate of 34.10 (95% UI, 32.63-35.38) deaths per 100 000 persons were due to infectious diseases in the United States compared to a total of 72 220 (95% UI, 69 887-74 712) deaths or a rate of 41.95 (95% UI, 40.52-43.42) deaths per 100 000 persons in 1980, an overall decrease of 18.73% (95% UI, 14.95%-23.33%). Lower respiratory infections were the leading cause of infectious diseases mortality in 2014 accounting for 26.87 (95% UI, 25.79-28.05) deaths per 100 000 persons (78.80% of total infectious diseases deaths). There were substantial differences among counties in death rates from all infectious diseases. Lower respiratory infection had the largest absolute mortality inequality among counties (difference between the 10th and 90th percentile of the distribution, 24.5 deaths per 100 000 persons). However, HIV/AIDS had the highest relative mortality inequality between counties (10.0 as the ratio of mortality rate in the 90th and 10th percentile of the distribution). Mortality from meningitis and tuberculosis decreased over the study period in all US counties. However, diarrheal diseases were the only cause of infectious diseases mortality to increase from 2000 to 2014, reaching a rate of 2.41 (95% UI, 0.86-2.67) deaths per 100 000 persons, with many counties of high mortality extending from Missouri to the northeastern region of the United States. Conclusions and Relevance: Between 1980 and 2014, there were declines in mortality from most categories of infectious diseases, with large differences among US counties. However, over this time there was an increase in mortality for diarrheal diseases. PMID- 29584844 TI - Hypothermia. PMID- 29584842 TI - Association of Placebo, Indomethacin, Ibuprofen, and Acetaminophen With Closure of Hemodynamically Significant Patent Ductus Arteriosus in Preterm Infants: A Systematic Review and Meta-analysis. AB - Importance: Despite increasing emphasis on conservative management of patent ductus arteriosus (PDA) in preterm infants, different pharmacotherapeutic interventions are used to treat those developing a hemodynamically significant PDA. Objectives: To estimate the relative likelihood of hemodynamically significant PDA closure with common pharmacotherapeutic interventions and to compare adverse event rates. Data Sources and Study Selection: The databases of MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from inception until August 15, 2015, and updated on December 31, 2017, along with conference proceedings up to December 2017. Randomized clinical trials that enrolled preterm infants with a gestational age younger than 37 weeks treated with intravenous or oral indomethacin, ibuprofen, or acetaminophen vs each other, placebo, or no treatment for a clinically or echocardiographically diagnosed hemodynamically significant PDA. Data Extraction and Synthesis: Data were independently extracted in pairs by 6 reviewers and synthesized with Bayesian random-effects network meta-analyses. Main Outcomes and Measures: Primary outcome: hemodynamically significant PDA closure; secondary: included surgical closure, mortality, necrotizing enterocolitis, and intraventricular hemorrhage. Results: In 68 randomized clinical trials of 4802 infants, 14 different variations of indomethacin, ibuprofen, or acetaminophen were used as treatment modalities. The overall PDA closure rate was 67.4% (2867 of 4256 infants). A high dose of oral ibuprofen was associated with a significantly higher odds of PDA closure vs a standard dose of intravenous ibuprofen (odds ratio [OR], 3.59; 95% credible interval [CrI], 1.64-8.17; absolute risk difference, 199 [95% CrI, 95-258] more per 1000 infants) and a standard dose of intravenous indomethacin (OR, 2.35 [95% CrI, 1.08-5.31]; absolute risk difference, 124 [95% CrI, 14-188] more per 1000 infants). Based on the ranking statistics, a high dose of oral ibuprofen ranked as the best pharmacotherapeutic option for PDA closure (mean surface under the cumulative ranking [SUCRA] curve, 0.89 [SD, 0.12]) and to prevent surgical PDA ligation (mean SUCRA, 0.98 [SD, 0.08]). There was no significant difference in the odds of mortality, necrotizing enterocolitis, or intraventricular hemorrhage with use of placebo or no treatment compared with any of the other treatment modalities. Conclusions and Relevance: A high dose of oral ibuprofen was associated with a higher likelihood of hemodynamically significant PDA closure vs standard doses of intravenous ibuprofen or intravenous indomethacin; placebo or no treatment did not significantly change the likelihood of mortality, necrotizing enterocolitis, or intraventricular hemorrhage.

AB - Importance: About 40 000 Americans and 2 million people worldwide are newly infected with HIV each year. The combination antiretroviral regimen, tenofovir disoproxil fumarate (TDF)/emtricitabine, taken as a single pill once daily, has been shown to prevent HIV transmission but is used by fewer than 20% of people who could benefit in the United States. Observations: PubMed was searched on February 15, 2018, using the search terms pre-exposure, prophylaxis, HIV, and PrEP to identify English-language articles published between 2010 and 2018. Four placebo-controlled randomized clinical trials have demonstrated that preexposure prophylaxis (PrEP) with daily dosing of TDF/emtricitabine significantly reduces HIV acquisition in men who have sex with men, high-risk heterosexuals, and injection drug users who share injection equipment. The efficacy of daily TDF/emtricitabine exceeds 90% but is highly correlated with degree of adherence. TDF/emtricitabine is safe and well-tolerated. Only 2% of people discontinue PrEP because of adverse effects. Sexually transmitted infections are common among those using PrEP. Resistance to TDF/emtricitabine when used for PrEP is rare (<0.1%) and usually occurs when PrEP is inadvertently prescribed to individuals with undiagnosed acute HIV infection who have false-negative findings on HIV antibody/antigen testing due to HIV infection acquired within 7 to 10 days of testing. Effective methods are needed to identify individuals at high risk for acquiring HIV, ensure their access to PrEP, and maximize medication adherence. Conclusions and Relevance: TDF/emtricitabine is an effective and safe therapy for preventing HIV transmission. Increasing prescription of TDF/emtricitabine for patients at risk of acquiring HIV has the potential to reduce new HIV infections. PMID- 29584851 TI - Drug-Resistant Infections from Raw Milk.

PMID- 29584853 TI - The importance of a comprehensive evaluation of survivors of cardiac arrest. PMID- 29584854 TI - Reoperative sternotomy is associated with primary graft dysfunction following heart transplantation. AB - OBJECTIVES: Prior sternotomy is associated with increased morbidity and mortality following heart transplantation. However, its effect on primary graft dysfunction (PGD), a major contributor to early mortality, is unknown. Herein, this effect is studied using the International Society for Heart and Lung Transplantation consensus definition for PGD. METHODS: Medical records of consecutive adult cardiac transplants between 2012 and 2016 were reviewed. Baseline characteristics, postoperative findings and 1-year survival were compared between patients with and without prior sternotomy. RESULTS: Among 255 total patients included, 139 (55%) had undergone prior sternotomy; these recipients were older, more often male, had higher body mass index, higher frequencies of united network for organ sharing (UNOS) 1A status and ischaemic cardiomyopathy and experienced longer waitlist times when compared with those without prior sternotomy (all P < 0.018). Postoperatively, the prior sternotomy group exhibited higher rates of mild to severe PGD (32% vs 18%; P = 0.015) and higher short-term mortality (P = 0.017) and 1-year mortality (P = 0.047). They required more blood transfusions, had more postoperative pneumonia, wound infection and longer hospital stays. A stepwise multivariable regression model identified prior sternotomy as a predictor of PGD (odds ratio 2.7). Multiple prior sternotomies was associated with even more UNOS 1A status, ischaemic cardiomyopathy and pneumonia. However, logistic modelling did not show a difference in the rate of PGD between those with 1 or >=2 prior sternotomies. CONCLUSIONS: Our data suggest that prior sternotomy is a risk factor for PGD. Consistent with previous reports, prior sternotomy is associated with increased morbidity, blood product utilization and 1-year mortality following cardiac transplantation. PMID- 29584855 TI - Outcomes of the Warden procedure for partial anomalous pulmonary venous drainage in children. AB - OBJECTIVES: When drainage of an anomalous pulmonary vein is high into the superior vena cava (SVC), traditional techniques of 1-patch or 2-patch repair may be challenging. The cavoatrial anastomosis technique (the Warden procedure) was developed to reduce the risk of sinus node dysfunction and SVC obstruction. Herein, we describe the outcomes of the Warden procedure in children at a single institution. METHODS: A retrospective study was conducted on all children with partial anomalous pulmonary venous drainage (PAPVD) undergoing the Warden procedure from 1996 to 2015. RESULTS: There were 42 PAPVD patients with a right upper pulmonary vein entering into the SVC undergoing the Warden procedure. The mean age of the patients at surgery was 5.5 years (71 days to 15.4 years). There was no operative mortality. Median hospital stay was 5 (3-25) days. One (2.4%) patient developed cavoatrial (SVC) obstruction. This patient required percutaneous intervention (stenting and balloon dilatation). There was 1 (2.4%) late death in a patient with PAPVD and pulmonary atresia due to a hypoxic brain injury following catheter intervention for a stenotic conduit. Survival was 97 +/ 3% (95% confidence interval 83-100%) at 5 and 7 years. All patients were asymptomatic at a mean follow-up of 6 years (range 1 month to 21 years) after surgery. No patient had sick sinus syndrome, sinus node dysfunction or required permanent pacemaker at follow-up. CONCLUSIONS: The Warden procedure for repair of PAPVD to the SVC can be performed with no operative mortality or permanent pacemaker requirement. Mid-term outcomes are excellent with a low occurrence of SVC obstruction. PMID- 29584856 TI - Oral doxycycline for syphilitic uveitis: a case report highlighting potential efficacy. PMID- 29584858 TI - Incidence and factors associated with infective endocarditis in patients undergoing left-sided heart valve replacement. AB - Aims: Patients with left-sided heart valve replacement are considered at high risk of infective endocarditis (IE). However, data on the incidence and risk factors associated with IE are sparse. Methods and results: Through Danish administrative registries, we identified patients who underwent left-sided heart valve replacement from January 1996 to December 2015. Patients were categorized in mitral and aortic valve replacement (MVR and AVR) and followed until: 12 years after valve surgery, end of study, death, emigration, or hospitalization due to IE, whichever came first. Multivariable adjusted Cox proportional hazard analysis was used to investigate which baseline characteristics were associated with IE. A total of 18 041 patients were included. The cumulative IE risk at 10 years follow up was 5.2% in both MVR and AVR patients. In patients with MVR, male sex [hazard ratio (HR) = 1.68, 95% confidence interval (95% CI) 1.06-2.68], bioprosthetic valve (HR = 1.91, 95% CI 1.08-3.37), and heart failure (HR = 1.69, 95% CI 1.06 2.68) were among factors associated with an increased risk of IE. In AVR patients, male sex (HR = 1.59, 95% CI 1.33-1.89), bioprosthetic valve (HR = 1.70, 95% CI 1.35-2.15), and cardiac implantable electronic device (CIED) (HR = 1.57, 95% CI 1.19-2.06) were among factors associated with an increased risk of IE. Conclusion: Infective endocarditis after left-sided heart valve replacement is not uncommon and occurs in about 1/20 over 10 years. Male, bioprosthetic valve, and heart failure were among factors associated with IE in MVR patients while male, bioprosthetic valve, and CIED were among factors associated with IE in AVR patients. PMID- 29584857 TI - Impaired Muscle Efficiency but Preserved Peripheral Hemodynamics and Mitochondrial Function With Advancing Age: Evidence From Exercise in the Young, Old, and Oldest-Old. AB - Muscle weakness in the elderly has been linked to recurrent falls and morbidity; therefore, elucidating the mechanisms contributing to the loss of muscle function and mobility with advancing age is critical. To this aim, we comprehensively examined skeletal muscle metabolic function and hemodynamics in 11 young (23 +/- 2 years), 11 old (68 +/- 2 years), and 10 oldest-old (84 +/- 2 years) physical activity-matched participants. Specifically, oxidative stress markers, mitochondrial function, and the ATP cost of contraction as well as peripheral hemodynamics were assessed during dynamic plantar flexion exercise at 40 per cent of maximal work rate (WRmax). Both the PCr recovery time constant and the peak rate of mitochondrial ATP synthesis were not significantly different between groups. In contrast, the ATP cost of dynamic contractions (young: 1.5 +/- 1.0, old: 3.4 +/- 2.1, oldest-old: 6.1 +/- 3.6 mM min-1 W-1) and systemic markers of oxidative stress were signficantly increased with age, with the ATP cost of contraction being negatively correlated with WRmax (r = .59, p < .05). End-of exercise blood flow per Watt rose significantly with increasing age (young: 37 +/ 20, old: 82 +/- 68, oldest-old: 154 +/- 93 mL min-1 W-1). These findings suggest that the progressive deterioration of muscle contractile efficiency with advancing age may play an important role in the decline in skeletal muscle functional capacity in the elderly. PMID- 29584859 TI - Loss-of-function mutations in FGF8 can be independent risk factors for holoprosencephaly. AB - The utilization of next generation sequencing has been shown to accelerate gene discovery in human disease. However, our confidence in the correct disease associations of rare variants continues to depend on functional analysis. Here, we employ a sensitive assay of human FGF8 variants in zebrafish to demonstrate that the spectrum of isoforms of FGF8 produced by alternative splicing can provide key insights into the genetic susceptibility to human malformations. In addition, we describe novel mutations in the FGF core structure that have both subtle and profound effects on ligand posttranslational processing and biological activity. Finally, we solve a case of apparent digenic inheritance of novel variants in SHH and FGF8, two genes known to functionally coregulate each other in the developing forebrain, as a simpler case of FGF8 diminished function. PMID- 29584860 TI - Substance Use During Imprisonment in Low- and Middle-Income Countries. AB - Substance use disorders are among the most common health problems of people involved with the criminal justice system. Scaling up addiction services in prisons is a global public health and human rights challenge, especially in poorly resourced countries. We systematically reviewed the prevalence of substance use in prison populations in low- and middle-income countries. We searched for studies reporting prevalence rates of nicotine, alcohol, illicit drug, and injection drug use during imprisonment in unselected samples of imprisoned people in low- and middle-income countries. Data meta-analysis was conducted and sources of heterogeneity were examined by meta-regression. Prevalence of nicotine use during imprisonment ranged from 5% to 87%, with a random-effects pooled estimate of 56% (95% confidence interval (CI): 45, 66) with significant geographical heterogeneity. Alcohol use varied from 1% to 76% (pooled prevalence, 16%, 95% CI: 9, 25). Approximately one-quarter of people (25%; 95% CI: 17, 33; range, 0-78) used illicit drugs during imprisonment. The prevalence of injection drug use varied from 0% to 26% (pooled estimate, 1.6%, 95% CI: 0.8, 3.0). Lifetime substance use was investigated in secondary analyses. The high prevalence of smoking in prison suggests that policies regarding smoking need careful review. Furthermore, the findings underscore the importance of timely, scalable, and available treatments for alcohol and illegal drug use by people involved with the criminal justice system. PMID- 29584861 TI - Linezolid pharmacokinetics in MDR-TB: a systematic review, meta-analysis and Monte Carlo simulation. AB - Objectives: The oxazolidinone linezolid is an effective component of drug resistant TB treatment, but its use is limited by toxicity and the optimum dose is uncertain. Current strategies are not informed by clinical pharmacokinetic (PK)/pharmacodynamic (PD) data; we aimed to address this gap. Methods: We defined linezolid PK/PD targets for efficacy (fAUC0-24:MIC >119 mg/L/h) and safety (fCmin <1.38 mg/L). We extracted individual-level linezolid PK data from existing studies on TB patients and performed meta-analysis, producing summary estimates of fAUC0-24 and fCmin for published doses. Combining these with a published MIC distribution, we performed Monte Carlo simulations of target attainment. Results: The efficacy target was attained in all simulated individuals at 300 mg q12h and 600 mg q12h, but only 20.7% missed the safety target at 300 mg q12h versus 98.5% at 600 mg q12h. Although suggesting 300 mg q12h should be used preferentially, these data were reliant on a single centre. Efficacy and safety targets were missed by 41.0% and 24.2%, respectively, at 300 mg q24h and by 44.6% and 27.5%, respectively, at 600 mg q24h. However, the confounding effect of between-study heterogeneity on target attainment for q24h regimens was considerable. Conclusions: Linezolid dosing at 300 mg q12h may retain the efficacy of the 600 mg q12h licensed dosing with improved safety. Data to evaluate commonly used 300 mg q24h and 600 mg q24h doses are limited. Comprehensive, prospectively obtained PK/PD data for linezolid doses in drug-resistant TB treatment are required.

Health professionals publish pro-influenza vaccination messages online to encourage proactive seeking of influenza vaccination. However, influenza vaccine coverage among the Japanese population is less than optimal. The contents of pro- and anti influenza vaccination websites may contribute to readers' acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing content on websites for and against influenza vaccination. We conducted online searches in January 2017 using two major Japanese search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as 'pro', 'anti' or 'neutral' depending on their claims, with author(s) classified as 'health professionals', 'mass media' or 'laypersons'. Text-mining analysis was conducted, and statistical analysis was performed using a chi-squared test. Of the 334 websites analyzed, 13 content topics were identified. The three most frequently appearing content topics on pro-vaccination websites were vaccination effect for preventing serious cases of influenza, side effects of vaccination, and efficacy rate of vaccination. The three most frequent topics on anti-vaccination websites were ineffectiveness of influenza vaccination, toxicity of vaccination, and side effects of vaccination. The main disseminators of each topic, by author classification, were also revealed. We discuss possible tactics of online influenza vaccination promotion to counter anti-vaccination websites.

PMID- 29584865 TI - The Admission of Older People Into Residential Care Homes in Argentina: Coercion and Human Rights Abuse. AB - Background and Objectives: There is very little information about the appropriateness of procedures for admitting older people into care homes in low and middle-income countries like Argentina. This study provides the first systematic study of practice and assesses the extent to which current practice respects fundamental human rights. Research Design and Methods: We apply different methods, including document review and national survey analysis. The study also includes a case study of a single city, La Plata, which draws on local key informant interviews, focus group discussions in different neighborhoods, and a clandestine surrogate patient survey led by local pensioners. This innovative design provides a highly triangulated and contextualized data set. Results: Many older people admitted to care homes did not have high levels of care dependency. Care homes did not usually require or even seek the informed consent of older people, regardless of their cognitive status. There were indications of coercive admission by family members, sometimes in order to obtain access to older people's homes and other property and finances. Discussion and Implications: The study indicates the widespread abuse of the fundamental human rights of tens of thousands of older people in Argentina. There is a need for researchers, policy makers, and civil society to acknowledge the scale of abuse and develop safeguards. PMID- 29584866 TI - Levels of serum brain-derived neurotropic factor in individuals at ultra-high risk for psychosis - Findings from the Longitudinal Youth at Risk Study (LYRIKS). AB - Background: Identifying biomarkers to enrich prognostication and risk predictions in individuals at high risk of developing psychosis will enable stratified early intervention efforts. Brain-derived neurotrophic factor (BDNF) has been widely studied in schizophrenia and in first-episode psychosis with promising results. The aim of this study was to examine the levels of serum BDNF between healthy controls and individuals with ultra-high risk of psychosis (UHR). Methods: A sample of 106 healthy controls and 105 UHR individuals from the Longitudinal Youth at Risk Study was included in this study. UHR status was determined using the Comprehensive Assessment of At-Risk Mental State (CAARMS) at recruitment. Calgary Depression Scale for Schizophrenia (CDSS) was used to assess the severity of depression. All participants were followed up over 2 years and UHR remitters were defined by UHR individuals who no longer fulfilled CAARMS criteria at the end of the study period. Levels of BDNF were measured in the serum by enzyme linked immunosorbent assay method (ELISA). Results: The UHR group had significantly higher baseline levels of serum BDNF compared with control group (3.7 vs. 3.3 ng/ml, p=0.018). However, baseline levels of serum BDNF did not predict the development of psychosis (OR=0.64, CI = 0.40 - 1.02) or remission (OR=0.83, CI = 0.60 - 1.15) from UHR status. Conclusion: Findings from our study did not support a role for serum BDNF in predicting outcomes in UHR individuals. However, the finding of higher levels of serum BDNF in UHR individuals deserves further study.

PMID- 29584868 TI - Antiretroviral Therapy and Mortality in Rural South Africa: A Comparison of Causal Modeling Approaches. AB - Estimation of causal effects from observational data is a primary goal of epidemiology. The use of multiple methods with different assumptions relating to exchangeability improves causal inference by demonstrating robustness across assumptions. We estimate the effect of antiretroviral therapy (ART) on mortality in rural KwaZulu-Natal, South Africa from 2007-2011 using two methods with substantially different assumptions: the regression discontinuity design (RDD), and inverse probability weighting of marginal structural models (IPW). The RDD analysis took advantage of a CD4 count-based threshold for ART initiation (200 cells/MUl). The two methods yielded consistent but non-identical results for the effect of immediate initiation of ART (RDD intention-to-treat hazards ratio (HR) 0.66, 95% CI 0.35 to 1.26; RDD HR 0.56, 95% CI 0.41 to 0.77; IPW HR 0.49, 95% CI 0.42 to 0.58). Although RDD and IPW estimates had distinct identifying assumptions, strengths, and limitations in terms of internal and external validity, results in this application were similar. The differences in modeling approaches and external validity of each method may explain the minor differences in effect estimates, but the consistency of the results lends support for causal inference of the effect of ART and mortality from these data.

PMID- 29584869 TI - The Health of America's Aging Prison Population. AB - Older incarcerated individuals comprise the fastest growing demographic in the US prison system. Unhealthy lifestyles among incarcerated individuals and inadequate health care lead to earlier onset and more rapid progression of many chronic conditions that are prevalent among community-living older adults. There are limited peer-reviewed epidemiologic data in this area; however, there is growing interest in identifying strategies for housing aging incarcerated individuals, delivering appropriate health care in prisons, and coordinating after-release health care. In this systematic review, we summarize the epidemiologic evidence of the health challenges facing the aging US prison population. Our comprehensive literature search focused on health outcomes, including diseases, comorbid conditions, mental health, cognition, and mobility. From 12,486 articles identified from the literature search, we reviewed 21 studies published between 2007 and 2017. All the studies were observational and cross-sectional, and most (n = 17) were based on regional samples. Sample sizes varied widely, ranging from 25 to 14,499 incarcerated people (median, 258). In general, compared with their younger counterparts, older incarcerated individuals reported high rates of diabetes mellitus, cardiovascular conditions, and liver disease. Mental health problems were common, especially anxiety, fear of desire for death or suicide, and depression. Activities of daily living were challenging for up to one-fifth of the population. We found no empirical data on cognition among older incarcerated individuals. The findings of this review reveal few empirical data in this area and highlight the need for new data to drive policy and practice patterns that address critical health issues related to the aging prison population.

PMID- 29584872 TI - Sliding of a single lac repressor protein along DNA is tuned by DNA sequence and molecular switching. AB - In any living cell, genome maintenance is carried out by DNA-binding proteins that recognize specific sequences among a vast amount of DNA. This includes fundamental processes such as DNA replication, DNA repair, and gene expression and regulation. Here, we study the mechanism of DNA target search by a single lac repressor protein (LacI) with ultrafast force-clamp spectroscopy, a sub millisecond and few base-pair resolution technique based on laser tweezers. We measure 1D-diffusion of proteins on DNA at physiological salt concentrations with 20 bp resolution and find that sliding of LacI along DNA is sequence dependent. We show that only allosterically activated LacI slides along non-specific DNA sequences during target search, whereas the inhibited conformation does not support sliding and weakly interacts with DNA. Moreover, we find that LacI undergoes a load-dependent conformational change when it switches between sliding and strong binding to the target sequence. Our data reveal how DNA sequence and molecular switching regulate LacI target search process and provide a comprehensive model of facilitated diffusion for LacI. PMID- 29584874 TI - Secondhand Smoke Exposure among High Risk Patients in The U.S. (NHANES 2001 2012): Implications for Clinical Practice. AB - Introduction: Patients with cancer, cardiovascular disease (CVD), and respiratory disease are susceptible to health consequences related to secondhand smoke (SHS) exposure. The current study examined the prevalence, time-trends and correlates of SHS exposure among these patients compared to individuals without these diseases (control). Methods: Data were obtained from the 2001-2012 National Health and Nutrition Examination Survey. All adults (>20 years old), who were nonsmokers and exposed to SHS (serum cotinine level 0.015-10 ng/mL), had cancer (n=1,440), CVD (congestive heart failure, coronary heart disease, angina, heart attack, or stroke; n=1,754), respiratory disease (asthma, chronic bronchitis, emphysema; n=1,444), or none of these diseases (control; n=11,615) were included in the analysis. Weighted prevalence, weighted second degree polynomial linear regression of prevalence on year for trend analysis, and multivariable logistic regression analyses were performed with adjustments to the complex survey design. Results: SHS exposure was the highest among patients with respiratory disease (72.1%), followed by CVD (70.6%), controls (70.4%) and cancer patients (65.4%). From 2001 to 2012, exposure decreased the most among CVD patients (19.6%), followed by controls (16.0%), cancer patients (14.7%), and respiratory patients (10.0%). Exposed individuals in all groups were more likely to be younger, Black, and less educated. Exposed patients with respiratory disease were more likely to be former smokers (P <.05 for all). Conclusions: SHS exposure among these patients is high and comparable to the general population. Strengthening smoke free polices in all settings is critical. More efforts are needed to address SHS exposure more effectively in clinical care settings. Implications: Despite the negative health effect of SHS exposure among patients with cancer, CVD and respiratory disease, modest progress has been made in reducing their exposure. Continued efforts to strengthen smoke-free polices in workplaces, public place, and multi-unit housing is critical. In addition, exposure to SHS among these patients seems to be overlooked in clinical care settings. More efforts are needed to address this problem more effectively in healthcare settings and investigate specific interventions directed at increasing patients' awareness about the risk of exposure to SHS and helping them reducing their exposure. PMID- 29584875 TI - Urine and Serum Sex Steroid Profile in Testosterone-Treated Transgender and Hypogonadal and Healthy Control Men. AB - Background: The impact of testosterone (T) treatment on antidoping detection tests in female-to-male (F2M) transgender men is unknown. We investigated urine and serum sex steroid and luteinizing hormone (LH) profiles in T-treated F2M men to determine whether and, if so, how they differed from hypogonadal and healthy control men. Method: Healthy transgender (n = 23) and hypogonadal (n = 24) men aged 18 to 50 years treated with 1000 mg injectable T undecanoate provided trough urine and blood samples and an additional earlier postinjection sample (n = 21). Healthy control men (n = 20) provided a single blood and urine sample. Steroids were measured by mass spectrometry-based methods in urine and serum, LH by immunoassay, and uridine 5'-diphospho-glucuronosyltransferase 2B17 genotype by polymerase chain reaction. Results: Urine LH, human chorionic gonadotropin, T, epitestosterone (EpiT), androsterone (A), etiocholanolone (Etio), A/Etio ratio, dehydroepiandrosterone (DHEA), dihydrotestosterone (DHT), and 5alpha,3alpha- and 5beta,3alpha-androstanediols did not differ between groups or by time since last T injection. Urine T/EpiT ratio was <4 in all controls and 12/68 (18%) samples from T-treated men, but there was no difference between T-treated groups. Serum estradiol, estrone, and DHEA were higher in transgender men, and serum T and DHT were higher in earlier compared with trough blood samples, but serum LH, follicle stimulating hormone, and 3alpha- and 3beta,5alpha-diols did not differ between groups. Conclusion: Urine antidoping detection tests in T-treated transgender men can be interpreted like those of T-treated hypogonadal men and are unaffected by time since last T dose. Serum steroids are more sensitive to detect exogenous T administration early but not later after the last T dose. PMID- 29584877 TI - Erratum. PMID- 29584876 TI - Paired D10A Cas9 nickases are sometimes more efficient than individual nucleases for gene disruption. AB - The use of paired Cas9 nickases instead of Cas9 nuclease drastically reduces off target effects. Because both nickases must function for a nickase pair to make a double-strand break, the efficiency of paired nickases can intuitively be expected to be lower than that of either corresponding nuclease alone. Here, we carefully compared the gene-disrupting efficiency of Cas9 paired nickases with that of nucleases. Interestingly, the T7E1 assay and deep sequencing showed that on-target efficiency of paired D10A Cas9 nickases was frequently comparable, but sometimes higher than that of either corresponding nucleases in mammalian cells. As the underlying mechanism, we found that the HNH domain, which is preserved in the D10A Cas9 nickase, has higher activity than the RuvC domain in mammalian cells. In this study, we showed: (i) the in vivo cleavage efficiency of the HNH domain of Cas9 in mammalian cells is higher than that of the RuvC domain, (ii) paired Cas9 nickases are sometimes more efficient than individual nucleases for gene disruption. We envision that our findings which were overlooked in previous reports will serve as a new potential guideline for tool selection for CRISPR Cas9-mediated gene disruption, facilitating efficient and precise genome editing. PMID- 29584878 TI - Increases in Human Papillomavirus Vaccination Among Adolescent and Young Adult Males in the United States, 2011-2016. AB - In the United States, human papillomavirus (HPV) vaccination has been recommended for females since 2006 and males since 2011. We assessed temporal trends in HPV vaccine coverage (defined as receipt of >=1 dose) among 9-26-year-old participants in the 2011-2016 National Health and Nutrition Examination Surveys. While coverage increased overall, from 37.7% to 45.7%, among females (adjusted prevalence difference [aPD], 7.1%; 95% confidence interval [CI], .1%-13.7%), there was no change among female adolescents aged 9-17 years. For males, coverage increased overall, from 7.8% to 27.4% (aPD, 18.8%; 95% CI, 14.1%-23.5%), and among every stratum of age, race/ethnicity, health insurance status, poverty level, and immigration status (P <= .05). The increase in HPV vaccine coverage observed among males is encouraging, but coverage remains below national targets for both males and females. PMID- 29584879 TI - Loss of RNA-binding protein HuR facilitates cellular senescence through posttranscriptional regulation of TIN2 mRNA. AB - Cellular senescence can be induced by high levels of reactive oxygen species (ROS) produced by mitochondria. However, the mechanism by which elevated mitochondrial ROS levels are produced during replicative senescence is not yet fully understood. Here, we report that loss of the RNA-binding protein, human antigen R (HuR), during replicative senescence leads to an increase in ROS levels through enhanced mitochondrial localization of the telomeric protein TIN2. HuR binds to the 3' untranslated region of TIN2 mRNA. This association decreases TIN2 protein levels by both destabilizing TIN2 mRNA and reducing its translation. Conversely, depletion of HuR levels enhances TIN2 expression, leading to increased mitochondrial targeting of TIN2. Mitochondrial localization of TIN2 increases ROS levels, which contributes to induction and maintenance of cellular senescence. Our findings provide compelling evidence for a novel role of HuR in controlling the process of cellular senescence by regulating TIN2-mediated mitochondrial ROS production, and for a useful therapeutic route for modulating intracellular ROS levels in treating both aging-related complications and cancer. PMID- 29584880 TI - Morbidity and housing status 10 years after shelter use-follow-up of homeless men in Helsinki, Finland. AB - Background: Homelessness is associated with increased mortality, morbidity and social difficulties and periods of homelessness are sometimes prolonged or repeated. However, there are no long-term follow-up studies focusing upon housing status among homeless people. The aim of this study was to examine morbidity and housing outcomes and to identify factors predicting being independently housed 10 years after shelter use. Methods: By combining data from several registers we followed all 552 homeless men who stayed in shelter in Helsinki during 2004 and determined their housing situation and morbidity 10 years later. Their situation was compared with an age-matched control group from the general population (N = 946). Using logistic regression analysis, we assessed the predictive effects of socioeconomic factors and health service use at baseline on becoming independently housed. Results: By the end of the follow-up 52.0% of the formerly homeless study group had died, compared with 14.6% of the controls. At 10 years, 6.0% were independently housed, 37.5% lived in supported housing and 4.5% were still or again homeless. Psychiatric disorders, including substance use disorder, were present in 77.5% of the homeless, compared with 16.1% among the controls. Being married (OR 8.3, 95% CI 3.0 to 23.2) and having less than four shelter nights in year 2004 (OR 9.1, 95% CI 2.7 to 30.8) strongly predicted being independently housed 10 years later. Conclusions: Homeless staying in shelters have high mortality and morbidity and most of those surviving, are in need of support in their everyday lives even years after the shelter period.

AB - The use of ribavirin to treat Crimean-Congo hemorrhagic fever virus (CCHFV) infection has been controversial, based on uncertainties about its antiviral efficacy in clinical case studies. We studied the effect of ribavirin treatment on viral populations in a recent case by deep-sequencing analysis of plasma samples obtained from a CCHFV-infected patient before, during, and after a 5-day regimen of ribavirin treatment. The CCHFV load dropped during ribavirin treatment, and subclonal diversity (transitions) and indels increased in viral genomes during treatment. Although the results are based on a single case, these data demonstrate the mutagenic effect of ribavirin on CCHFV in vivo.

PMID- 29584888 TI - Estimating Monitoring Trap Plume Reach and Trapping Area for Drosophila suzukii (Diptera: Drosophilidae) in Michigan Tart Cherry. AB - Central-monitoring trap, multiple point release-recapture experiments were used to interpret Drosophila suzukii (Diptera: Drosophilidae) catch in a monitoring trap baited with a Scentry Biologicals commercial D. suzukii lure deployed in Michigan tart cherry orchards. The plume reach was found to be short (<3 m), while the maximum dispersive distance for 95% of the released D. suzukii was projected to be ca. 90 m, so as to yield a trapping area of 2.7 ha. These data were consistent across two growing seasons and provide the first information about the dispersal distance and monitoring trap efficacy in a fruit crop setting for D. suzukii. Catch data per single monitoring trap can now be used to estimate absolute pest density in cherries. Alarmingly, catching one D. suzukii in a monitoring trap translates to approximately 192 D. suzukii per trapping area of 2.7 ha (26 per acre). Thus, by the time D. suzukii catch becomes detectable, it is very probable that the population is already above the tolerable damage threshold, suggesting control measures should immediately be taken if the fruit is in a vulnerable stage. Caution should be taken when extrapolating these results from cherry because the measured values may differ in other crop systems. PMID- 29584887 TI - National survey of myeloablative total body irradiation prior to hematopoietic stem cell transplantation in Japan: survey of the Japanese Radiation Oncology Study Group (JROSG). AB - A myeloablative regimen that includes total-body irradiation (TBI) before hematopoietic stem cell transplantation results in higher patient survival rates than achieved with regimens without TBI. The TBI protocol, however, varies between institutions. In October 2015, the Japanese Radiation Oncology Study Group initiated a national survey of myeloablative TBI (covering 2010-2014). Among the 186 Japanese institutions performing TBI, 90 (48%) responded. The 82 institutions that had performed myeloablative TBI during this period treated 2698 patients with malignant disease [leukemia (2082 patients, 77.2%), malignant lymphoma (378, 14%)] and 37 with non-malignant disease [severe aplastic anemia (20, 54%), inborn errors of metabolism (5, 14%)]. A linear accelerator was used at all institutions. The institutions were divided into 41 large and 41 small institutions based on the median number of patients. The long source-surface distance technique was the method of choice in the 34 institutions (82.9%) and the moving-couch technique in the 7 (17.1%) in the large institutions. The schedules most routinely used by the participating institutions consisted of 12 Gy/6 fractions/3 days (26 institutions, 63.5%) in the large institutions. The dose rate varied from 5 to 26 cGy/min. The lungs and lenses were routinely shielded in 23 large institutions (56.1%), and only the lungs in 9 large institutions (21.9%). At lung-shielding institutions, the most frequent maximum acceptable total dose for the lungs was 8 Gy (19 institutions, 27.5%). Our results reveal considerable differences in the TBI methods used by Japanese institutions and thus the challenges in designing multicenter randomized trials based on TBI. PMID- 29584889 TI - Longitudinal Assessment of Illnesses, Stress Dosing, and Illness Sequelae in Patients With Congenital Adrenal Hyperplasia. AB - Context: Patients with congenital adrenal hyperplasia (CAH) are at risk for life threatening adrenal crises. Management of illness episodes aims to prevent adrenal crises. Objective: We evaluated rates of illnesses and associated factors in patients with CAH followed prospectively and receiving repeated glucocorticoid stress dosing education. Methods: Longitudinal analysis of 156 patients with CAH followed at the National Institutes of Health Clinical Center over 23 years was performed. The rates of illnesses and stress-dose days, emergency room (ER) visits, hospitalizations, and adrenal crises were analyzed in relation to phenotype, age, sex, treatment, and hormonal evaluations. Results: A total of 2298 visits were evaluated. Patients were followed for 9.3 +/- 6.0 years. During childhood, there were more illness episodes and stress dosing than adulthood (P < 0.001); however, more ER visits and hospitalizations occurred during adulthood (P <= 0.03). The most robust predictors of stress dosing were young age, low hydrocortisone and high fludrocortisone dose during childhood, and female sex during adulthood. Gastrointestinal and upper respiratory tract infections (URIs) were the two most common precipitating events for adrenal crises and hospitalizations across all ages. Adrenal crisis with probable hypoglycemia occurred in 11 pediatric patients (ages 1.1 to 11.3 years). Undetectable epinephrine was associated with ER visits during childhood (P = 0.03) and illness episodes during adulthood (P = 0.03). Conclusions: Repeated stress-related glucocorticoid dosing teaching is essential, but revised age-appropriate guidelines for the management of infectious illnesses are needed for patients with adrenal insufficiency that aim to reduce adrenal crises and prevent hypoglycemia, particularly in children. PMID- 29584890 TI - Effectiveness of an Anger Intervention for Military Members with PTSD: A Clinical Case Series. AB - Objective: Problematic anger is a significant clinical issue in military personnel, and is further complicated by comorbid post-traumatic stress disorder (PTSD). Despite increasing numbers of military personnel returning from deployment with anger and aggression difficulties, the treatment of problematic anger has received scant attention. There are currently no interventions that directly target problematic anger in the context of military-related PTSD. The aim of this case series is to examine the effectiveness of an intervention specifically developed for treating problematic anger in current serving military personnel with comorbid PTSD. Methods: Eight Australian Defence Force Army personnel with problematic anger and comorbid PTSD received a manualized 12 session cognitive behaviorally based anger intervention, delivered one-to-one by Australian Defence Force mental health clinicians. Standardized measures of anger, PTSD, depression, and anxiety were administered pre- and post-treatment. Results: The initial mean severity scores for anger indicated a high degree of pre-treatment problematic anger. Anger scores reduced significantly from pre to post-treatment (d = 1.56), with 88% of participants exhibiting meaningful reduction in anger scores. PTSD symptoms also reduced significantly (d= 0.96), with 63% of participants experiencing a clinically meaningful reduction in PTSD scores. All of those who took part in the therapy completed all therapy sessions. Conclusions: This brief report provides preliminary evidence that an intervention for problematic anger not only significantly reduces anger levels in military personnel, but can also significantly reduce PTSD symptoms. Given that anger can interfere with PTSD treatment outcomes, prioritizing anger treatment may improve the effectiveness of PTSD interventions. PMID- 29584891 TI - Unveiling the pathway to Z-DNA in the protein-induced B-Z transition. AB - Left-handed Z-DNA is an extraordinary conformation of DNA, which can form by special sequences under specific biological, chemical or physical conditions. Human ADAR1, prototypic Z-DNA binding protein (ZBP), binds to Z-DNA with high affinity. Utilizing single-molecule FRET assays for Z-DNA forming sequences embedded in a long inactive DNA, we measure thermodynamic populations of ADAR1 bound DNA conformations in both GC and TG repeat sequences. Based on a statistical physics model, we determined quantitatively the affinities of ADAR1 to both Z-form and B-form of these sequences. We also reported what pathways it takes to induce the B-Z transition in those sequences. Due to the high junction energy, an intermediate B* state has to accumulate prior to the B-Z transition. Our study showing the stable B* state supports the active picture for the protein induced B-Z transition that occurs under a physiological setting. PMID- 29584892 TI - AN AUTHOR REPLIES. PMID- 29584893 TI - Increase in Childhood Nontuberculous Mycobacterial Infections After Bacille Calmette-Guerin Coverage Drop: A Nationwide, Population-Based Retrospective Study, Finland, 1995-2016. AB - Background: Epidemiological data on childhood nontuberculous mycobacterial (NTM) disease is scarce and the protective effect of bacille Calmette-Guerin (BCG) vaccination remains debated. In 2006, the BCG policy in Finland changed from universal to selective. We aimed to study the effect of the BCG coverage decrease on the incidence of childhood NTM infections in Finland. Methods: We conducted a nationwide, population-based, retrospective study of NTM notifications recorded to the National Infectious Diseases Register between 1995 and 2016 and identified native-born children aged 0-4 years infected with NTM. Poisson log-linear model was used to estimate the change in the incidence rate of cohorts born during universal or selective BCG policy between 1995 and 2015. Results: We identified 97 native-born children aged <5 years infected with NTM (median age, 27 months; female-to-male ratio, 2:1). The most common species was Mycobacterium avium (n = 69 [71%]). The estimated incidence rates of NTM in universal-BCG and selective BCG cohorts were 0.2 and 3.9 per 100000 person-years, respectively. The incidence rate ratio of selective-BCG cohorts compared to universal-BCG cohorts was 19.03 (95% confidence interval, 8.82-41.07; P < .001). Conclusions: After infant BCG coverage in Finland decreased, childhood NTM infections increased drastically. As there is no other apparent cause for the increase, this indicates that BCG offers protection against childhood NTM disease. This observation adds to the understanding of childhood NTM epidemiology and might explain why the disease is emerging in some countries. PMID- 29584894 TI - Parity Increases Insulin Requirements in Pregnant Women With Type 1 Diabetes. AB - Context: Tight glycemic control throughout pregnancy in women with type 1 diabetes is crucial, and knowledge about which factors that affect insulin sensitivity could improve the outcome for both mother and offspring. Objective: To evaluate insulin requirements in women with type 1 diabetes during pregnancy and test whether parity affects insulin requirements. Design: Observational cohort study consisting of women with type 1 diabetes who gave birth at Aarhus University Hospital, Denmark, from 2004 to 2014. Main Outcome Measure: Daily insulin requirement (the hypothesis that parity could affect insulin resistance was formulated before data collection). Results: A total of 380 women with a total of 536 pregnancies were included in the study. Mean age was 31.1 years, and prepregnancy hemoglobin A1c was 60 mmol/mol. Parity was as follows: P0, 43%; P1, 40%; P2, 14%; and P3+4, 3%. Insulin requirements from weeks 11 to 16 decreased significantly by 4% (P = 0.0004) and rose from week 19 to delivery with a peak of 70% (P < 0.0005) at weeks 33 to 36. Overall, insulin requirements increased significantly with parity. The unadjusted differences between P0 and P1, P2, and P3+4 were 9% (P < 0.0005), 12% (P < 0.0005), and 23% (P < 0.0011), respectively. After adjustment for confounders, differences were 13% (P < 0.0005), 20% (P < 0.0005), and 36% (P < 0.0005). We also observed an adjusted difference between P1 and P3+4 of 20% (P < 0.0012). Conclusions: The data show changes in insulin requirements from week to week in pregnancy and indicate that insulin requirements increase with parity. This suggests that the patient's parity probably should be considered in choosing insulin dosages for pregnant women with type 1 diabetes. PMID- 29584895 TI - Reducing falls in older adults recently discharged from hospital: a systematic review and meta-analysis. AB - Background: older adults are known to have increased falls rates and functional decline following hospital discharge, with substantial economic healthcare costs. This systematic review aimed to synthesise the evidence for effective falls prevention interventions in older adults recently discharged from hospital. Methods: literature searches of six databases of quantitative studies conducted from 1990 to June 2017, reporting falls outcomes of falls prevention interventions for community-dwelling older adults discharged from hospital were included. Study quality was assessed using a standardised JBI critical appraisal tool (MAStARI) and data pooled using Rev-Man Review Manager(r). Results: sixteen studies (total sample size N = 3,290, from eight countries, mean age 77) comprising 12 interventions met inclusion criteria. We found home hazard modification interventions delivered to those with a previous falls history (1 study), was effective in reducing the number of falls (RR 0.63, 95%CI 0.43, 0.93, Low GRADE evidence). Home exercise interventions (3 studies) significantly increased the proportion of fallers (OR 1.74, 95%CI 1.17, 2.60, Moderate GRADE evidence), and did not significantly reduce falls rate (RR 1.27, 95%CI 0.99, 1.62, Very Low GRADE evidence) or falls injury rate (RR 1.16, 95%CI, 0.83,1.63, Low GRADE evidence). Nutritional supplementation for malnourished older adults (1 study) significantly reduced the proportion of fallers (HR 0.41, 95% CI 0.19, 0.86, Low GRADE evidence). Conclusion: the recommended falls prevention interventions for older adults recently discharged from hospital are to provide home hazard minimisation particularly if they have a recent previous falls history and consider nutritional supplementation if they are malnourished. PMID- 29584896 TI - Interactive medical word sense disambiguation through informed learning. AB - Objective: Medical word sense disambiguation (WSD) is challenging and often requires significant training with data labeled by domain experts. This work aims to develop an interactive learning algorithm that makes efficient use of expert's domain knowledge in building high-quality medical WSD models with minimal human effort. Methods: We developed an interactive learning algorithm with expert labeling instances and features. An expert can provide supervision in 3 ways: labeling instances, specifying indicative words of a sense, and highlighting supporting evidence in a labeled instance. The algorithm learns from these labels and iteratively selects the most informative instances to ask for future labels. Our evaluation used 3 WSD corpora: 198 ambiguous terms from Medical Subject Headings (MSH) as MEDLINE indexing terms, 74 ambiguous abbreviations in clinical notes from the University of Minnesota (UMN), and 24 ambiguous abbreviations in clinical notes from Vanderbilt University Hospital (VUH). For each ambiguous term and each learning algorithm, a learning curve that plots the accuracy on the test set against the number of labeled instances was generated. The area under the learning curve was used as the primary evaluation metric. Results: Our interactive learning algorithm significantly outperformed active learning, the previous fastest learning algorithm for medical WSD. Compared to active learning, it achieved 90% accuracy for the MSH corpus with 42% less labeling effort, 35% less labeling effort for the UMN corpus, and 16% less labeling effort for the VUH corpus. Conclusions: High-quality WSD models can be efficiently trained with minimal supervision by inviting experts to label informative instances and provide domain knowledge through labeling/highlighting contextual features. PMID- 29584898 TI - AN ANALYSIS OF OPERATING PHYSICIAN AND PATIENT RADIATION EXPOSURE DURING RADIAL CORONARY ANGIOPLASTIES. AB - The objective of this study was to evaluate radiation exposure levels in conjunction with operator dose implemented, patient vascular characteristics, and other technical angiographic parameters. In total, 756 radial coronary angioplasties were evaluated in a major metropolitan general hospital in Tabriz, Iran. The classification of coronary lesions was based on the ACC/AHA system. One interventional cardiologist performed all of the procedures using a single angiography unit. The mean kerma-area product and mean cumulative dose for all cases was 5081 MUGy m2 and 814.44 mGy, respectively. Average times of 26.16 and 9.1 min were recorded for the overall procedure and fluoroscopy, respectively. A strong correlation was demonstrated between types of lesions, number of stents and vessels treated in relation to physician radiation exposure. It was determined that operator radiation exposure levels for percutaneous coronary interventions lesions (complex) were higher than that of simple and moderate lesions. In addition, operator radiation exposure levels increased with the treatment of more coronary vessels and implementation of additional stents. PMID- 29584897 TI - Magnetic resonance imaging guidance for the optimization of ventricular tachycardia ablation. AB - Catheter ablation has an important role in the management of patients with ventricular tachycardia (VT) but is limited by modest long-term success rates. Magnetic resonance imaging (MRI) can provide valuable anatomic and functional information as well as potentially improve identification of target sites for ablation. A major limitation of current MRI protocols is the spatial resolution required to identify the areas of tissue responsible for VT but recent developments have led to new strategies which may improve substrate assessment. Potential ways in which detailed information gained from MRI may be utilized during electrophysiology procedures include image integration or performing a procedure under real-time MRI guidance. Image integration allows pre-procedural magnetic resonance (MR) images to be registered with electroanatomical maps to help guide VT ablation and has shown promise in preliminary studies. However, multiple errors can arise during this process due to the registration technique used, changes in ventricular geometry between the time of MRI and the ablation procedure, respiratory and cardiac motion. As isthmus sites may only be a few millimetres wide, reducing these errors may be critical to improve outcomes in VT ablation. Real-time MR-guided intervention has emerged as an alternative solution to address the limitations of pre-acquired imaging to guide ablation. There is now a growing body of literature describing the feasibility, techniques, and potential applications of real-time MR-guided electrophysiology. We review whether real-time MR-guided intervention could be applied in the setting of VT ablation and the potential challenges that need to be overcome. PMID- 29584899 TI - Verification and Determination of the Thyroid Peroxidase Antibody Reference Interval: Insight Into the CLSI Guideline. AB - Objective: To verify the upper reference limit and define the population-based reference interval (RI) for thyroid peroxidase antibody, according to Clinical and Laboratory Standards Institute (CLSI) guidelines. Material and Methods: We subjected serum samples from 146 subjects to thyroid-stimulating hormone (TSH) and TPO Ab analysis for verification and determination of RI. We verified an upper reference limit for thyroid peroxidase antibody (TPO Ab) and established an RI according to National Academy of Clinical Biochemistry (NACB) and CLSI guidelines. Results: The manufacturer's suggested upper reference limit was not verified for use as a functional reference value. Rather, on defining the RI of TPO Ab by means of a full-scale study, we found a higher upper reference limit (13.8 vs 12.0). We calculated lower and upper reference limits of 3.3 and 13.8, with 90% confidence intervals (CIs) of 2.8 to 3.5 and 13.6 to 14.8, respectively. Conclusion: RIs provided by assay manufacturers are general data and may not always be appropriate for different locations and patient demographics. Verification of an RI is necessary before use in a given patient population. PMID- 29584900 TI - Comment on: IgG4-related disease presenting with raised serum IgG2-real timeline of IgG4-RD?: reply.

PMID- 29584902 TI - OPTIMIZATION OF A RADIOPHOTOLUMINESCENT GLASS DOSEMETER FOR OCCUPATIONAL EYE LENS DOSIMETRY IN INTERVENTIONAL RADIOLOGY/CARDIOLOGY. AB - Hospital based workers that perform interventional radiology are at risk of reaching the eye lens dose limit of 20 mSv/y. These workers are exposed to the radiation scattered by the patient, which creates a complex field, with low radiation energy reaching the eyes of the medical staff from wide angles. Therefore, the dosemeter used in the assessment of the eye lens dose of interventional radiologists needs to respond accurately in such conditions. In this study, the angular response of a commercially available radiophotoluminescent glass dosemeter, GD-352M, was optimized via Monte Carlo simulations, aiming at its use as eye lens dosemeter in interventional radiology. The improved dosemeter was manufactured and then characterized in terms of Hp(3), the quantity recommended for eye lens dosimetry. Its response was compared to the IEC 62387:2012 requirements for Hp(3) and to requirements proposed specifically for eye lens dosemeters used in interventional radiology. The improved dosemeter meets the IEC 62387:2012 requirements for energy and angular response for Hp(3) and also shows good agreement with the more strict requisites proposed for eye lens dosemeters to be used in interventional radiology.

PMID- 29584905 TI - Effects of production systems on the carcass and meat quality characteristics of spent laying hens. AB - This study evaluated the carcass characteristics and meat quality attributes of spent laying hens raised under conventional battery cage and free-range systems. Thirty free-range and 30 conventional battery-caged Lohmann Brown-Elite spent laying hens of 53 and 40 wk of age, respectively were obtained from a commercial egg producer. Carcass, portion, and organ weights and percentages were determined. Physicochemical analyses were performed on thigh and breast meat samples. Caged hens had heavier (P <= 0.05) warm and cold carcasses, thighs, wings, and feet. The percentages of the breast (26.1 +/- 0.51 vs. 28.3 +/- 0.28), drum, breast bones, breast thaw and cooking loss, and thigh cooking loss were higher (P <= 0.05) for free-range than for caged hens. Free-range hens had heavy (P <= 0.05) gizzards (33.9 +/- 1.04 vs. 30.5 +/- 0.73) and bones and a lower (P <= 0.05) breast meat percentage (47.3 +/- 0.94 vs. 51.7 +/- 1.35). Meat redness (a*) (0.54 +/- 0.222 vs. 1.40 +/- 0.135) and hue angle, skin redness (a*), breast (12.37 +/- 0.411 vs. 17.10 +/- 0.751), and thigh (29.68 +/- 0.306 vs. 39.75 +/- 0.826) Warner-Bratzler shear force values (N), breast moisture, and thigh ash content were higher (P <= 0.05) for free-range hens. Caged hens had a higher (P <= 0.05) thigh thaw loss percentage and breast ash content. Production system significantly influenced the carcass characteristics and meat quality of spent laying hens. The results of this study supply baseline information for the utilization of spent laying hens by the poultry industry and consumers. PMID- 29584904 TI - Combined Pathologies in FTLD-TDP Types A and C. AB - This study investigated the presence of combined pathologies in a large cohort of autopsies that show a primary pathologic diagnosis of phosphorylated 43-kDa TAR DNA-binding protein (FTLD-TDP), the majority of which portrayed clinical phenotypes consistent with primary progressive aphasia or behavioral variant frontotemporal dementia (bvFTD). Thirty-eight cases with FTLD-TDP (30 type-A and 8 type-C) were identified to determine characteristic differences between cases with and without combined pathologies. Findings indicated that combined pathologies co-occur with FTLD-TDP type-A at a high frequency (50%)-greater than when compared to FTLD-TDP type-C cases (12.5%). Those with FTLD-TDP type-A and combined pathologies showed significantly longer lifespans (p < 0.05), and longer disease durations (p < 0.05), than those with only FTLD-TDP type-A. Cases with FTLD-TDP type-A and known genetic mutations tended not to show combined pathology. Those with the GRN mutation and FTLD-TDP type-A showed a significantly younger age of onset (p < 0.05) and younger age at death (p < 0.01) compared to noncarriers. In 1 bvFTD case, we highlight the rare presence of "triple" FTLD-TDP type-A, FTLD-tau, and Alzheimer pathology. The ante- and post-mortem features associated with combined pathologies in FTLD-related disorders are of useful consideration in the stratification of patients to drug trials, and in the development of therapeutic targets for FTLD. PMID- 29584906 TI - Capillary leak syndrome in Daboia russelii bite-a complication associated with poor outcome. AB - Background: Capillary leak syndrome (CLS) has been previously observed as a complication of Daboia russelii bite but not clearly defined or studied in length. This observational case-control study evaluates the mortality along with associated clinical and laboratory features. Methods: Twenty-five patients who developed CLS were compared with 25 patients without CLS following Daboia russelii (Russell's viper) bite. Results: Development of CLS is associated with a significantly high risk of mortality; 11 (44%) patients with CLS died compared with 1 (4%) control (odds ratio 18.8 [95% confidence interval 2.2 to 161.99], p=0.002). Disease-defining manifestations included myalgia (22 [88%]), thirst (20 [80%]), parotid swelling (15 [60%]), conjunctival chemosis (19 [76%]) and hypotension (22 [88%]), which were unobserved in controls. Although several clinical and laboratory parameters were found to be predictive for development of CLS in univariate analysis, none of them had independent predictive value in multivariate analysis. Similarly, development of parotid swelling was the only factor with independent predictive value for mortality in multivariate analysis. Even though the number of vials of snake antivenom used is more in CLS, it seems unlikely to improve the mortality in CLS. Conclusions: This study proves that CLS is a well-defined complication of Russell's viper bite with high mortality but with clear predictors for the development of CLS and mortality.

AB - Iodine-131 is one of the main concerns from the point of view of radiological protection in a short term after a nuclear accident. The WBC Laboratory of CIEMAT has developed a methodology for in vivo monitoring of radioiodine in the thyroid of exposed individuals in case of emergency. Thyroid-neck phantoms of different sizes are required for calibrating the detection systems in appropriate counting geometries for the measurement of exposed population. A Low-Energy Germanium (LEGe) detector and a Fastscan Counter were calibrated using a set of thyroid phantoms fabricated by CIEMAT. Each neck phantom consists of a Lucite cylinder with a vial source of 131I. Counting efficiencies depending on age and thyroid sizes were obtained to be used to determine the activity of 131I in internally contaminated people. DL of 131I varies with the age, being in the range of 5-8 Bq for the LEGe detector and 26-42 Bq for the Fastscan. Detection of intakes resulting in Committed Effective doses far below 1 mSv are guaranteed for thyroid monitoring in a few days after the accidental exposure assuming a scenario of acute inhalation or ingestion of 131I by members of the public.

PMID- 29584910 TI - Week 96 efficacy of lopinavir/ritonavir monotherapy in virologically suppressed patients with HIV: a randomized non-inferiority trial (ANRS 140 DREAM). AB - Background: Sparing of antiretroviral drug classes could reduce the toxicity and cost of maintenance treatment for HIV infection. Objectives: To evaluate the non inferiority of efficacy and the safety of lopinavir/ritonavir (r) monotherapy versus a single-tablet regimen of efavirenz, emtricitabine and tenofovir (EFV/FTC/TDF) over 2 years. Methods: Adults on stable ART with plasma HIV-1 RNA viral load <50 copies/mL for the past 12 months and no documented treatment failure were randomized to receive either lopinavir/r or EFV/FTC/TDF for 2 years. The primary endpoint was the proportion of patients without treatment failure at week 96 (viral load <50 copies/mL at week 96, confirmed at week 98), without study treatment discontinuation, a new AIDS-defining illness, or death. Results: In the ITT analysis, the primary endpoint was reached by, respectively, 64% and 71% of patients in the lopinavir/r (n = 98) and EFV/FTC/TDF arms (n = 97), yielding a difference of -6.8% (lower limit of the 95% two-sided CI: -19.9%). Sanger and UltraDeep sequencing showed the occurrence of PI mutations in the lopinavir/r arm (n = 4) and of NNRTI and/or NRTI mutations in the EFV/FTC/TDF arm (n = 2). No unexpected serious clinical events occurred. Conclusions: Lopinavir/r monotherapy cannot be considered non-inferior to EFV/FTC/TDF. PI resistance rarely emerged in the lopinavir/r arm and did not undermine future PI options. Two years of lopinavir/r monotherapy had no deleterious clinical impact when compared with EFV/FTC/TDF. PMID- 29584911 TI - Organ recovery cost assessment in the French healthcare system from 2007 to 2014. AB - Background: Organ recovery costs should be assessed to allow efficient and sustainable integration of these costs into national healthcare budgets and policies. These costs are of considerable interest to health economists, hospitals, financial managers and policy makers in most developed countries. This study assessed organ recovery costs from 2007 to 2014 in the French healthcare system based on the national hospital discharge database and a national cost study. The secondary objective was to describe the variability in the population of deceased organ donors during this period. Methods: All stays for organ recovery in French hospitals between January 2007 and December 2014 were quantified from discharge abstracts and valued using a national cost study. Five cost evaluations were conducted to explore all aspects of organ recovery activities. A sensitivity analysis was conducted to test the methodological choice. Trends regarding organ recovery practices were assessed by monitoring indicators. Results: The analysis included 12 629 brain death donors, with 28 482 organs recovered. The mean cost of a hospital stay was ?7469 (SD = ?10, 894). The mean costs of separate kidney, liver, pancreas, intestine, heart, lung and heart lung block recovery regardless of the organs recovered were ?1432 (SD = ?1342), ?502 (SD = ?782), ?354 (SD = ?475), ?362 (SD = ?1559), ?542 (SD = ?955), ?977 (SD = ?1196) and ?737 (SD = ?637), respectively. Despite a marginal increase in donors, the number of organs recovered increased primarily due to improved practices. Conclusion: Although cost management is the main challenge for successful organ recovery, other aspects such as organization modalities should be considered to improve organ availability. PMID- 29584912 TI - Stress preconditioning of rooster semen before cryopreservation improves fertility potential of thawed sperm. AB - Avian semen cryopreservation is not as successful as that seen in mammals. This failure is mostly attributed to unique physiological characteristics of poultry semen that make it susceptible to cryo-damages. Utilization of sublethal oxidative stress for preconditioning of sperm, as an innovative approach, improves the cryo-survival of sperm in certain mammalian species. The purpose of this study was to investigate the effects of preconditioning of rooster semen with sublethal oxidative stress [very low concentrations of nitric oxide (NO)] before cryopreservation on the quality and fertility potential of thawed sperm. Semen samples were collected from 20 roosters, twice a wk, and different concentrations of NO [0 (NO-0), 0.01 (NO-0.01), 0.1 (NO-0.1), 1 (NO-1), 10 (NO 10), and 100 MUM (NO-100)] were used to investigate the effects of controlled induction of sublethal stress before semen cryopreservation on the thawed sperm performance. A significantly higher (P < 0.05) percentage of total motility was observed in semen treated with NO-1 compared to NO-0, NO-0.01, NO-0.1, NO-10, and NO-100. NO-1 and NO-100 produced the highest and lowest percentages of progressive motility, which were significantly different from that of the other groups (P < 0.05). A significantly higher (P < 0.05) percentage of sperm mitochondria activity was observed in semen exposed to NO-0, NO-0.01, NO-0.1, and NO-1. Moreover, the lowest (P < 0.05) concentration of malondialdehyde (MDA) was measured in samples treated with NO-1 in comparison to the other groups. Abnormal morphology, acrosome integrity, and velocity parameters [velocity average path (VAP) and linearity (LIN)] of sperm were not significantly (P > 0.05) affected by different concentrations of NO. Sperm exposed to NO-1 produced the highest percentage of viable spermatozoa (Annexin-/PI-), which was significantly different from the other samples. Finally, rate of fertility after artificial insemination was significantly higher (P < 0.05) following treatment with NO-1 compared to NO-0 and NO-0.1. Application of 1 MUM NO as a sublethal oxidative stress before cryopreservation of sperm efficiently increased numerous quality indices of thawed sperm as well as its fertility potential. PMID- 29584913 TI - Development of Saudi e-health literacy scale for chronic diseases in Saudi Arabia: using integrated health literacy dimensions. AB - Objective: Health literacy has become a global issue, and it is important that patients and individuals are able to use information technology to access health information and educational services. The research objective is to develop a Saudi e-health literacy scale (SeHL) for measuring e-health literacy among Saudis suffering from non-communicable diseases (NCD). Methods: Overall, 14 relevant papers in related interdisciplinary fields were reviewed to select the most useful literacy dimensions. From these articles, we extracted the most common dimensions used to measure e-health literacy across the disciplines. Multiple workshops with multidisciplinary team members reviewed and evaluated items for SeHL. Results: Four key aspects of e-health literacy-use of technology/media, information-seeking, usefulness and confidence-were identified and integrated as e-health literacy dimensions. These will be used to measure e-health literacy among Saudi patients with NCDs. A translation from Arabic to English was performed in order to ensure that translation process was accurate. A SeHL scale was developed to measure e-health literacy among Saudi patients. By understanding e-health literacy levels, we will be able to create a patient-education system to be used by patients in Saudi Arabia. Conclusions: As information technology is increasingly used by people of all ages all over the world, e-health literacy has been identified as a key factor in determining health outcomes. To date, no comprehensive scale exists to assess e-health literacy levels among speakers of Arabic, particularly among people with NCD such as diabetes, cardiovascular diseases and hypertension. PMID- 29584915 TI - Interleukin-1 blockade in cardiovascular diseases: a clinical update. AB - Interleukin-1 (IL-1) is the prototypical pro-inflammatory cytokine. IL-1 was implicated as a cardiodepressant factor in septic shock, and subsequent pre clinical and clinical research has defined important roles for IL-1 in atherosclerosis, acute myocardial infarction (AMI), and heart failure (HF). IL-1 promotes the formation of the atherosclerotic plaque and facilitates its progression and complication. In a large phase III clinical trial of stable patients with prior AMI, blocking IL-1 activity using a monoclonal antibody prevented recurrent atherothrombotic cardiovascular events. IL-1 also contributes to adverse remodelling and left ventricular dysfunction after AMI, and in phase II studies, IL-1 blockade quenched the inflammatory response associated with ST segment elevation AMI and prevented HF. In patients with established HF, IL-1 is thought to impair beta-adrenergic receptor signalling and intracellular calcium handling. Phase II studies in patients with HF show improved exercise capacity with IL-1 blockade. Thus, IL-1 blockade is poised to enter the clinical arena as an additional strategy to reduce the residual cardiovascular risk and/or address inflammatory cardiovascular conditions refractory to standard treatments. There are several IL-1 blockers available for clinical use, which differ in mechanism of action, and potentially also efficacy and safety. While IL-1 blockade is not immunosuppressive and not associated with opportunistic infections or an increased risk of cancer, fatal infections may occur more frequently while on treatment with IL-1 blockers likely due to a blunting of the inflammatory signs of infection leading to delayed presentation and diagnosis. We discuss the practical use of IL-1 blockade, including considerations for patient selection and safety monitoring. PMID- 29584914 TI - Antimicrobial resistance of Enterococcus faecium strains isolated from commercial probiotic products used in cattle and swine. AB - Probiotics, an antibiotic alternative, are widely used as feed additives for performance benefits in cattle and swine production systems. Among bacterial species contained in probiotics, Enterococcus faecium is common. Antimicrobial resistance (AMR), particularly multidrug resistance, is a common trait among enterococci because of their propensity to acquire resistance and horizontally transfer AMR genes. Also, E. faecium is an opportunistic pathogen, and in the United States, it is the second most common nosocomial pathogen. There has been no published study on AMR and virulence potential in E. faecium contained in probiotic products used in cattle and swine in the United States. Therefore, our objectives were to determine phenotypic susceptibilities or resistance to antimicrobials, virulence genes (asa1, gelE, cylA, esp, and hyl) and assess genetic diversity of E. faecium isolated from commercial products. Twenty-two commercially available E. faecium-based probiotic products used in cattle (n = 13) and swine (n = 9) were procured and E. faecium was isolated and species confirmed. Antimicrobial susceptibility testing to determine minimum inhibitory concentrations was done by micro-broth dilution method using National Antimicrobial Resistance Monitoring Systems Gram-positive Sensititre panel plate (CMV3AGPF), and categorization of strains as susceptible or resistant was as per Clinical Laboratory and Standards Institute's guidelines. E. faecium strains from 7 products (3 for swine and 4 for cattle) were pan-susceptible to the 16 antimicrobials tested. Strains from 15 products (6 for swine and 9 for cattle) exhibited resistance to at least one antimicrobial and a high proportion of strains was resistant to lincomycin (10/22), followed by tetracycline (4/22), daptomycin (4/22), ciprofloxacin (4/22), kanamycin (3/22), and penicillin (2/22). Four strains were multidrug resistant, with resistant phenotypes ranging from 3 to 6 antimicrobials or class. None of the E. faecium strains were positive for any of the virulence genes tested. The clonal relationships among the 22 E. faecium strains were determined by pulsed-field gel electrophoresis (PFGE) typing. A total of 10 PFGE patterns were observed with 22 strains and a few of the strains from different probiotic products had identical (100% Dice similarity) PFGE patterns. In conclusion, the E. faecium strains in a few commercial probiotics exhibited AMR to medically-important antimicrobials, but none contained virulence genes. PMID- 29584916 TI - A Randomized, Multicenter, Double-Blind, Parallel Pilot Study Assessing the Effect of Mechanical Adhesiolysis vs Adhesiolysis with Corticosteroid and Hyaluronidase Administration into the Epidural Space During Epiduroscopy. AB - Objective: Epiduroscopy is a proven method of diagnosis and treatment for chronic radicular pain after spinal surgery, which is known as failed back surgery syndrome (FBSS). The aim of the study was to compare the efficacy of drugs (the enzyme hyaluronidase and corticosteroid DEPO-Medrol) administrated into the epidural space during epiduroscopy, performed within the ventral and ventro lateral epidural space with a focus on releasing foraminal adhesions. Methods: Forty-eight patients with diagnosed FBBS were randomized into two groups before epiduroscopy. Group A received the standard treatment-mechanical lysis of fibrotic tissue in the epidural space. Group B received hyaluronidase and corticosteroid methylprednisolone acetate during the procedure. Subjects were followed for six and 12 months via scheduled double-blinded examinations by pain physicians. Leg and back pain intensity was assessed by an 11-point numerical rating scale, and patients' functional disability was assessed by the Oswestry Disability Index (ODI). Results: Study subjects showed a significant decrease in ODI score in both groups (P < 0.05). Significantly lower pain scores for leg pain (P < 0.05) and back pain (P < 0.05) were also recorded after the six-month follow up. However, the one-year follow-up showed a return to the baseline ODI values of most monitored pain scores in both groups (P > 0.05). Improvement was only noted on the NRS for back pain at one-year follow-up (P < 0.05). Conclusions: A significant improvement of leg and back pain was found in both groups after six months. ODI was significantly improved only in group B in both the six- and 12 month intervals. Back pain at one-year follow-up was only improved in group B. PMID- 29584917 TI - The Effects of Nicotine and Tobacco use on Brain Reward Function: Interaction with Nicotine Dependence Severity. AB - Introduction: This study investigated the effects of nicotine/tobacco on neural activation during performance of a monetary incentivized delay task. Methods: Prior to each scan, nonsmokers received nicotine or placebo nasal spray and smokers were smoking satiated or 24-hours withdrawn. During the scan, participants made timed responses to reward-related cues and received feedback. Parameter estimates from cue- and feedback-related activation in medial prefrontal regions and the nucleus accumbens (NAcc) were extracted and underwent within- and between-group analyses. Smokers' nicotine dependence severity was included as a continuous predictor variable for neural activation. Results: Among smokers (n = 21), withdrawal decreased cue-related activation in the supplementary motor area and ventromedial prefrontal cortex, and the difference in activation (satiety > withdrawal) in these regions negatively correlated with nicotine dependence severity (Fagerstrom Test for Nicotine Dependence). Among nonsmokers (n = 22), nicotine increased the difference in NAcc activation between rewarded and non-rewarded feedback phases. Tobacco withdrawal and acute nicotine also had widespread effects on activation throughout the brain during the feedback phase. Conclusions: Acute nicotine in nonsmokers may have increased the salience of feedback information, but produced few effects on reward-related activation overall, perhaps reflecting nicotine's modest, indirect effects on reward processing. Conversely, tobacco withdrawal decreased activation compared to satiety, and this difference between conditions correlated with nicotine dependence severity. This suggests that as smokers become more dependent on nicotine, tobacco withdrawal has a more pronounced effect on reward processing. Implications: Relative to the acute effects of nicotine in nonsmokers, withdrawal from daily tobacco use had more significant effects on reward-related brain activation. This study suggests that the effects of tobacco withdrawal on reward related brain function interact with subjects' level of nicotine dependence severity. These are potentially important sources of variability that could contribute to smoking cessation outcomes. PMID- 29584918 TI - Human Immunization With a Polymorphic Malaria Vaccine Candidate Induced Antibodies to Conserved Epitopes That Promote Functional Antibodies to Multiple Parasite Strains. AB - Background: Overcoming antigenic diversity is a key challenge in the development of effective Plasmodium falciparum malaria vaccines. Strategies that promote the generation of antibodies targeting conserved epitopes of vaccine antigens may provide protection against diverse parasites strains. Understanding differences between vaccine-induced and naturally acquired immunity is important to achieving this goal. Methods: We analyzed antibodies generated in a phase 1 human vaccine trial, MSP2-C1, which included 2 allelic forms of MSP2, an abundant vaccine antigen on the merozoite surface. Vaccine-induced responses were assessed for functional activity against multiple parasite strains, and cross-reactivity of antibodies was determined using competition ELISA and epitope mapping approaches. Results: Vaccination induced cytophilic antibody responses with strain transcending opsonic phagocytosis and complement-fixing function. In contrast to antibodies acquired via natural infection, vaccine-induced antibodies were directed towards conserved epitopes at the C-terminus of MSP2, whereas naturally acquired antibodies mainly targeted polymorphic epitopes. Functional activity of C-terminal-targeted antibodies was confirmed using monoclonal antibodies that promoted opsonic phagocytosis against multiple parasite strains. Conclusion: Vaccination generated markedly different responses to polymorphic antigens than naturally acquired immunity and targeted conserved functional epitopes. Induction of antibodies targeting conserved regions of malaria antigens provides a promising vaccine strategy to overcome antigenic diversity for developing effective malaria vaccines.

AB - Background: Scrub typhus, caused by the intracellular bacteria Orientia tsutsugamushi is widely distributed in Southeast Asian countries with antigenically divergent strains reported across the Asia-Pacific belt. The present study was conducted to characterize the circulating strains of Orientia tsutsugamushi prevailing in two Northeastern states of India-the gateway to most Southeast Asian countries. Methods: A total of 278 (98 clinical and 180 field collected) scrub typhus positive blood samples collected from December 2014 to December 2016 were subjected for amplification of partial 56 KDa, 47 KDa and 16SrRNA genes of Orientia. Results: Highest number of PCR positives were obtained for 56 KDa gene (17.3%); followed by 11.2% for 47 KDa gene and 5.1% for 16S rRNA gene. High degree of genetic diversity was identified among the identified strains, especially within the 56 KDa gene. Different strains of Orientia circulate in the northeastern part of India, with a pre-dominance of Karp-like strains. Independently branched isolates formed distinct clades, suggesting the possibility of a new strain type of Orientia. Conclusion: This study provides insight into the genetic and evolutionary relationship of Orientia strains prevalent in this part of the country. Understanding the regional genetic diversity is crucial for its implications in vaccine developments strategies as well as sero-diagnostics.

PMID- 29584920 TI - Genomic Rearrangement Signatures and Clinical Outcomes in High-Grade Serous Ovarian Cancer. AB - Background: To identify clinically relevant genomic rearrangement signatures in high-grade serous ovarian cancer (HGSOC), we conducted a retrospective analysis of sequenced HGSOC whole-tumor genomes. Methods: Clinical data and whole-genome sequencing (WGS) reads were obtained for primary HGSOC tumors sequenced by the Australian Ovarian Cancer Study (AOCS; n = 80). Genomic rearrangements were identified, and non-negative matrix factorization (NMF) was used to extract rearrangement signatures. The cohort was then dichotomized around the median signature contribution, and overall survival (OS) was analyzed. An independent cohort from The Cancer Genome Atlas (TCGA) ovarian cancer study (n = 490) was also examined. The TCGA cohort was dichotomized around the median similarity between tumor copy number profile and a prognostic rearrangement signature, and OS was analyzed. Outcomes were assessed using Kaplan-Meier and multivariable Cox regression methods. All statistical tests were two-sided. Results: We identified five genomic rearrangement signatures (Ov.RS1-5) in HGSOC. Ov.RS3 exhibited 10 kilobase to 10 megabase deletions and tandem duplications, and patients whose tumors exhibited a high contribution from Ov.RS3 had poor OS. The median OS was 22.7 months (95% confidence interval [CI] = 20.2 to 39.0 months) in the Ov.RS3 high group vs 38.2 months (95% CI = 22.7 to 69.1 months) in the Ov.RS3-low group (hazard ratio [HR] = 1.86, 95% CI = 1.12 to 3.09, P = .02). For the independent TCGA cohort, median OS rates were 38.0 months (95% CI = 35.3 to 41.4 months) in the Ov.RS3 high-similarity group vs 48.9 months (95% CI = 44.1 to 57.1 months) in the Ov.RS3 low-similarity group (HR = 1.54, 95% CI = 1.21 to 1.97, P < .001). Conclusion: A novel genomic rearrangement signature is associated with poor prognosis in HGSOC. PMID- 29584921 TI - Toward methylation-based classification of central nervous system tumors.

AB - Grafting mantle tissue of a donor pearl oyster into the gonad of a recipient oyster results in the formation of a chimera, the pearl sac. The phenotypic variations of this chimera are hypothesized to be the result of interactions between the donor and recipient genomes. In this study, the heritability of phenotypic variation and its association with gene expression were investigated for the first time during Pinctada margaritifera pearl production. Genetic variance was evaluated at different levels, 1) before the graft operation (expression in graft tissue), 2) after grafting (pearl sac tissue expression in chimera), and 3) on the product of the graft (pearl phenotype traits) based on controlled biparental crosses and the F1 generation. Donor-related genetic parameter estimates clearly demonstrate heritability for nacre weight and thickness, darkness and color, and surface defects and grade, which signifies a genetic basis in the donor oyster. In graft relative gene expression, the value of heritability was superior to 0.20 in for almost all genes; whereas in pearl sac, heritability estimates were low (h2 < 0.10; except for CALC1 and Aspein). Pearl sac expression seems to be more influenced by residual variance than the graft, which can be explained by environmental effects that influence pearls sac gene expression and act as a recipient additive genetic component. The interactions between donor and recipient are very complex, and further research is required to understand the role of the recipient oysters on pearl phenotypic and gene expression variances. PMID- 29584923 TI - Rescue Therapy for Procedural Complications Associated With Deployment of Flow Diverting Devices in Cerebral Aneurysms. AB - Flow diverting devices (FDDs) have revolutionized the treatment of morphologically complex intracranial aneurysms such as wide-necked, giant, or fusiform aneurysms. Although FDDs are extremely effective, they carry a small yet significant risk of intraprocedural complications. As the implementation of these devices increases, the ability to predict and rapidly treat complications, especially those that are iatrogenic or intraprocedural in nature, is becoming increasingly more necessary.Our objective in this paper is to provide a descriptive summary of the various types of intraprocedural complications that may occur during FDDs deployment and how they may best be treated. A systematic and qualitative review of the literature was conducted using electronic databases MEDLINE and Google Scholar. Searches consisted of Boolean operators "AND" and "OR" for the following terms in different combinations: "aneurysm," "endovascular," "flow diverter," "intracranial," and "pipeline."A total of 94 papers were included in our analysis; approximately 87 of these papers dealt with periprocedural endovascular (mainly related to FDDs) complications and their treatment; 7 studies concerned background material. The main categories of periprocedural complications encountered during deployment of FDDs are failure of occlusion, parent vessel injury and/or rupture, spontaneous intraparenchymal hemorrhage, migration or malposition of the FDDs, thromboembolic or ischemic events, and side branch occlusionPeriprocedural complications occur mainly due to thromboembolic events or mechanical issues related to device deployment and placement. With increasing use and expanding versatility of FDDs, the understanding of these complications is vital in order to effectively manage such situations in a timely manner. PMID- 29584924 TI - An Open-label Randomized Controlled Trial to Compare Weight Gain of Very Low Birth Weight Babies with or without Addition of Coconut Oil to Breast Milk. AB - Background: Nutritional guidelines involving the feeding of very low birth weight babies (VLBW) recommend addition of Human Milk Fortifiers to breast milk. Owing to financial constraints, it is a practice in low- and middle-income countries (LMIC) to add coconut oil to aid better weight gain. There are inadequate data on improvement of growth parameters with oral coconut oil supplementation of breast milk. Methods: In this randomized controlled trial, we measured growth parameters and body composition of 60 babies who received either breast milk with coconut oil or breast milk alone. Randomization was stratified according to intrauterine growth appropriate for gestational age (n = 30) and small for gestational age (n = 30). Results: There was no difference in weight gain between the two groups. The weight gain velocity was 15 +/- 3.6 and 14.4 +/- 3.4 g/kg/day (p value = 0.49) in the breast milk alone and in the breast milk with coconut oil group, respectively. There was no difference in increase in head circumference and length. Triceps skinfold thickness (n = 56) was similar in both groups, but subscapular skinfold thickness was significantly more in the coconut oil group. Total body fat percentage did not differ between the groups (25.2 +/- 4.3 vs. 25.5 +/- 4.3%, p = 0.79). Conclusion: Oral supplementation of coconut oil along with breast milk did not increase growth parameters or result in change in body composition in very low birth weight (VLBW) babies. PMID- 29584925 TI - EVALUATING EXTREMELY LOW FREQUENCY MAGNETIC FIELDS IN THE REAR SEATS OF THE ELECTRIC VEHICLES. AB - In the electric vehicles (EVs), children can sit on a safety seat installed in the rear seats. Owing to their smaller physical dimensions, their heads, generally, are closer to the underfloor electrical systems where the magnetic field (MF) exposure is the greatest. In this study, the magnetic flux density (B) was measured in the rear seats of 10 different EVs, for different driving sessions. We used the measurement results from different heights corresponding to the locations of the heads of an adult and an infant to calculate the induced electric field (E-field) strength using anatomical human models. The results revealed that measured B fields in the rear seats were far below the reference levels by the International Commission on Non-Ionizing Radiation Protection. Although small children may be exposed to higher MF strength, induced E-field strengths were much lower than that of adults due to their particular physical dimensions. PMID- 29584926 TI - Evaluation of Complementary and Integrative Health Approaches Among US Veterans with Musculoskeletal Pain Using Propensity Score Methods. AB - Objectives: To examine the treatment effectiveness of complementary and integrative health approaches (CIH) on chronic pain using Propensity Score (PS) methods. Design, Settings, and Participants: A retrospective cohort of 309,277 veterans with chronic musculoskeletal pain assessed over three years after initial diagnosis. Methods: CIH exposure was defined as one or more clinical visits for massage, acupuncture, or chiropractic care. The treatment effect of CIH on self-rated pain intensity was examined using a longitudinal model. PS matching and inverse probability of treatment weighting (IPTW) were used to account for potential selection and confounding biases. Results: At baseline, veterans with (7,621) and without (301,656) CIH exposure differed significantly in 21 out of 35 covariates. During the follow-up period, on average CIH recipients had 0.83 (95% confidence interval [CI] = 0.77 to 0.89) points higher pain intensity ratings (range = 0-10) than nonrecipients. This apparent unfavorable effect size was reduced to 0.37 (95% CI = 0.28 to 0.45) after PS matching, 0.36 (95% CI = 0.29 to 0.44) with IPTW on the treated (IPTW-T) weighting, and diminished to null when integrating IPTW-T with PS matching (0.004, 95% CI = -0.09 to 0.10). An alternative IPTW model and conventional covariate adjustment appeared least powerful in terms of potential bias reduction. Sensitivity analyses restricting the follow-up period to one year after CIH initiation derived consistent results. Conclusions: PS-based causal methods successfully eliminated baseline difference between exposure groups in all measured covariates, yet they did not detect a significant difference in the self-rated pain intensity outcome between veterans who received CIHs and those who did not during the follow-up period.

AB - Objectives: To investigate in patients with chronic back pain of a short duration, the utility of adding structural MRI lesions of the SI joints to the imaging criterion of the Assessment of SpondyloArthritis International Society (ASAS) axial SpA (axSpA) criteria and the utility of replacement of radiographic sacroiliitis by structural MRI lesions. Methods: MRI STIR (inflammation, MRI-SI), MRI T1-weighted images (structural lesions, MRI-SI-s) and radiographs of the SI joints of patients in the SPondyloArthritis Caught Early-cohort (chronic back pain: ?3 months, ?2 years; onset <45 years) were scored by two well-calibrated readers. Previously proposed cut-offs for a positive MRI-SI-s were used (based on <5% prevalence in no-SpA patients): erosions ?3, fatty lesions ?3, fatty lesions and/or erosions (erosions/fatty lesions) ?5. Using the definitions of MRI-SI-s, patients were classified according to the ASAS axSpA criteria. Results: Twenty nine of 294 patients were modified New York (mNY) positive and 32 were MRI-SI-s positive (erosions/fatty lesions ?5). Agreement between mNY and MRI-SI-s (erosions/fatty lesions ?5) was moderate (kappa: 0.58). Using the erosions/fatty lesions ?5 cut-off, 3/294 additional patients were classified as axSpA (adding MRI). Using this cut-off instead of mNY (replacing mNY), classification did not change in 286 patients (97.3%), but 5 patients (1.7%) would not be classified as axSpA and 3 previously unclassified patients (1.0%) would be classified as axSpA. Similar results were seen for the other cut-offs (erosions ?3 and fatty lesions ?3). Conclusion: Assessment of structural lesions (fatty lesions and erosions) on MRI-SI instead of or in addition to conventional radiographs does not lead to a different ASAS axSpA classification in most of the patients with early disease onset. This suggests that structural lesions (fatty lesions and erosions) can be reliably used in the ASAS axSpA classification of patients, as both addition and replacement of radiographs of the SI joints. PMID- 29584928 TI - Thoracic enhanced recovery with ambulation after surgery: a 6-year experience. AB - OBJECTIVES: Our institution implemented a protocol known as thoracic enhanced recovery with ambulation after surgery (T-ERAS) in thoracic operations. The objective was early ambulation starting in the postoperative ambulatory care unit. METHODS: Video-assisted thoracoscopic surgery lobectomy patients are placed on a chair in the preoperative area and then walked to the operating room. Postoperatively, patients are placed on a chair as soon as possible. Our target ambulation goal was 250 feet within 1 h of extubation. Patients then walk to their hospital room. T-ERAS adoption and outcomes were compared to a pre-T-ERAS period, in addition to the comparing early and late T-ERAS cohorts. RESULTS: Over 6 years, 304 patients on T-ERAS underwent a planned video-assisted thoracoscopic surgery lobectomy. Median age was 67 years (range 41-87 years). The target goal was achieved in 187 of 304 (61.5%) patients and 277 of 304 (91.1%) patients ambulated 250 feet at any time in the postoperative ambulatory care unit. The T ERAS period had a median length of stay of 1 day vs 2 days in the pre-T-ERAS period (P < 0.001). There were low rates of pneumonia (2/304, 0.7%), atrial fibrillation (12/304, 4.0%) and no postoperative mortalities for T-ERAS. The target goal was achieved at a greater rate in the late (92/132, 72.0%) versus early (28/75, 37%) T-ERAS cohort. The mean time to ambulation was reduced in the late cohort (46-81 min). CONCLUSIONS: Early postoperative ambulation was feasible and considered key in achieving low morbidity after video-assisted thoracoscopic surgery lobectomy. Adoption of T-ERAS improved over time. Further studies will help define adoptability at other sites and validate impact on improving outcomes.

AB - We present the surface plasmon resonance modes in three-dimensional (3D) upright split ring resonators (SRR) as studied by correlative cathodoluminescence (CL) spectroscopy in a scanning electron microscope (SEM) and electron energy loss spectroscopy (EELS) in a transmission electron microscope. We discuss the challenges inherent in studying the plasmon modes of a 3D nanostructure and how meeting these challenges benefits from the complementary use of EELS and SEM-CL. With the use of EELS, we detect a strong first order mode in the SRR; with comparison to simulations, we are able to identify this as the well-known magnetic dipole moment of the SRR. Combining the EELS spectra with SEM-CL on the same structure reveals the higher order modes present in this 3D nanostructure, which we link to the coupling and hybridization of rim modes present in the two upright hollow pillars of the split ring.

AB - We evaluated the genetic relationships (1) among feed efficiency traits with different fattening periods, (2) between feed efficiency traits and growth traits, and (3) between feed efficiency traits and carcass traits, to determine the influence of genetic factors on feed efficiency traits. In total, 4,578 Japanese Black cattle from a progeny testing program were used. Residual feed intake (RFI), residual BW gain (RG), and residual intake and BW gain (RIG) were defined as feed efficiency traits, and were measured for the first half (approximately 9 to 15 months of age), latter half (approximately 15 to 21 months of age), and total period of fattening (approximately 9 to 21 months of age). A single-trait animal model for estimating heritability and a two-trait animal model for estimating genetic and phenotypic correlations were used. The heritability estimates for RFI, RG, and RIG were different in each fattening period, ranging from 0.36 to 0.46, 0.19 to 0.28, and 0.28 to 0.34, respectively, and the heritability estimates for the total fattening period were greater than those for the first and latter halves separately. RIG showed the greatest preferred genetic correlation, with a greater feed conversion ratio than the other feed efficiency traits (ranging from -0.84 to -0.96). RG in the first and latter halves of the fattening period had different genetic correlations with the growth starting point (0.82 and -0.06, respectively) and maturity rate (0.49 and 0.51, respectively) of the Gompertz growth curve parameters, and is strongly dependent on the different fattening periods. Feed efficiency traits in different fattening periods had low genetic correlations with the carcass traits (from 0.05 to 0.19 for RFI; from 0.02 to 0.31 for RG; and from -0.11 to 0.20 for RIG). This study indicated the possibility for genetic improvement through the selection of high-RIG animals to decrease feed intake and increase BW gain without any unfavorable correlated responses affecting mature (asymptotic) weight and carcass grade.

PMID- 29584932 TI - Structure-Dependent Modulation of Aryl Hydrocarbon Receptor-Mediated Activities by Flavonoids. AB - Dietary flavonoids are used in treatment of multiple diseases, and their antiinflammatory effects in the intestine are due, in part, to interactions with gut microflora and possibly due to modulation of aryl hydrocarbon receptor (AhR) signaling. In this study, we investigated the structure-dependent AhR activity of 14 flavonoids in Caco2 colon cancer cells using induction of CYP1A1 and UGT1A1 gene expression as endpoints. A major structural determinant for AhR activation was the number of hydroxyl groups where pentahydroxyflavonoids (with the exception of morin) > hexahydroxyflavonoids > tetra-/trihydroxyflavonoids, and some of the latter compounds such as apigenin exhibited AhR antagonist activity for induction of CYP1A1. Simulations suggest that while quercetin and apigenin interact primarily with the same residues, the strength of interactions between specific AhR residues with CYP1A1 agonist, quercetin, in comparison with CYP1A1 antagonist, apigenin, is different; thus, such interactions are presumably indicative of potential switches for modulating CYP1A1 activity. The structure dependent effects of the hydroxyl flavonoids on induction of UGT1A1 were similar to that observed for induction of CYP1A1 except that luteolin and apigenin induced UGT1A1 levels similar to that observed for TCDD, whereas both compounds were AhR antagonists for CYP1A1. Thus, the effects of the flavonoids in Caco2 cells on Ah-responsiveness and interactions with butyrate were both ligand structure- and response-dependent and these activities are consistent with hydroxyflavonoids being selective AhR modulators.

AB - A serial harvest was conducted every 28 d from 254 to 534 d on feed (DOF) to quantify changes in growth and composition of calf-fed Holstein steers (n = 115, initial body weight (BW) = 449.2 +/- 19.9 kg). One-half were supplemented with the beta-2 adrenergic agonist zilpaterol hydrochloride (ZH; 8.33 mg/kg 100% dry matter (DM) basis) during the final 20 d followed by a 3-d withdrawal prior to harvest; the remainder was fed a non-ZH control (CON) ration. Five steers were randomly selected and harvested after 226 DOF which served as a reference point for modeling purposes. Fabricated carcass soft tissue was ground, mixed, and subsampled for proximate analysis. Moreover, following the traditional method of rib dissection which includes the 9th, 10th, and 11th rib contained within the IMPS 103 primal, the relationship of carcass chemical composition to 9-10-11 rib composition was evaluated. Carcasses in this investigation had more (P < 0.01) separable lean, fat, ash, and moisture concomitant with less bone and ether extract than rib dissections. However, protein levels were similar (P = 0.27) between carcasses and rib dissections. Using regression procedures, models were constructed to describe the relationship of rib dissection (RD) composition including separable lean (RDSL), separable fat (RDSF), separable bone (RDSB), ether extract (RDEE), protein (RDP), moisture (RDM), and ash (RDA) with carcass composition. Carcass lean (CL), carcass fat (CF), and carcass bone (CB) were correlated (P < 0.01) with RDSL, RDSF, and RDSB with simple r values of 0.41, 0.71, and 0.50, respectively. Chemical composition of the rib and carcass, carcass ether extract (CEE), carcass protein (CP), carcass moisture (CM), and carcass ash (CA) were correlated (P <= 0.01) with simple r values of 0.75, 0.31, 0.66, and 0.37, respectively. Equations to predict carcass fatness from rib dissection variables and ZH supplementation status were only able to account for 50 and 56%, of the variability of CF and CEE, respectively. Overall, the relationships quantified and equations developed in this investigation do not support use of 9/10/11 rib dissection for estimation of carcass composition of calf-fed Holstein steers.

AB - Benzoxazinoids are a class of indole-derived plant metabolites that function in defense against numerous pests and pathogens. Due to their abundance in maize (Zea mays) and other important cereal crops, benzoxazinoids have been the subject of extensive research for >50 years. Whereas benzoxazinoids can account for 1% or more of the dry weight in young seedlings constitutively, their accumulation in older plants is induced locally by pest and pathogen attack. Although the biosynthetic pathways for most maize benzoxazinoids have been identified, unanswered questions remain about the developmental and defense-induced regulation of benzoxazinoid metabolism. Recent research shows that, in addition to their central role in the maize chemical defense repertoire, benzoxazinoids may have important functions in regulating other defense responses, flowering time, auxin metabolism, iron uptake and perhaps aluminum tolerance. Investigation of natural variation in maize benzoxazinoid accumulation, which is greatly facilitated by recent genomics advances, will have a major impact in this research area by leading to the discovery of previously unknown genes and functions of benzoxazinoid metabolism.

AB - Pyrolysis and oxidation of triethyl phosphate (TEP) were performed in the reflected shock region at temperatures of 1462-1673 K and 1213-1508 K, respectively, and at pressures near 1.3 atm. CO concentration time histories during the experiments were measured using laser absorption spectroscopy at 4580.4 nm. Experimental CO yields were compared with model predictions using the detailed organophosphorus compounds (OPC) incineration mechanism from the Lawrence Livermore National Lab (LLNL). The mechanism significantly underpredicts CO yield in TEP pyrolysis. During TEP oxidation, predicted rate of CO formation was significantly slower than the experimental results. Therefore, a new improved kinetic model for TEP combustion was developed, which was built upon the AramcoMech2.0 mechanism for C0-C2 chemistry and the existing LLNL submechanism for phosphorus chemistry. Thermochemical data of 40 phosphorus (P)-containing species were reevaluated, either using recently published group values for P containing species or by quantum chemical calculations (CBS-QB3). The new improved model is in better agreement with the experimental CO time histories within the temperature and pressure conditions tested in this study. Sensitivity analysis was used to identify important reactions affecting CO formation, and future experimental/theoretical studies on kinetic parameters of these reactions were suggested to further improve the model. To the best of our knowledge, this is the first study of TEP kinetics in a shock tube under these conditions and the first time-resolved laser-based species time history data during its pyrolysis and oxidation. PMID- 29584938 TI - Long-Range Self-Assembly via the Mutual Lorentz Force of Plasmon Radiation. AB - Long-range interactions often proceed as a sequence of hopping through intermediate, statistically favored events. Here, we demonstrate predictable mechanical dynamics of particles that arise from the Lorentz force between plasmons. Even if the radiation is weak, the nonconservative Lorentz force produces stable locations perpendicular to the plasmon oscillation; over time, distinct patterns emerge. Experimentally, linearly polarized light illumination leads to the formation of 80 nm diameter Au nanoparticle chains, perpendicularly aligned, with lengths that are orders of magnitude greater than their plasmon near-field interaction. There is a critical intensity threshold and optimal concentration for observing self-assembly. PMID- 29584937 TI - Collective Effects in Second-Harmonic Generation from Plasmonic Oligomers. AB - We investigate collective effects in plasmonic oligomers of different symmetries using second-harmonic generation (SHG) microscopy with cylindrical vector beams (CVBs). The oligomers consist of gold nanorods that have a longitudinal plasmon resonance close to the fundamental wavelength that is used for SHG excitation and whose long axes are arranged locally such that they follow the distribution of the transverse component of the electric field of radially or azimuthally polarized CVBs in the focal plane. We observe that SHG from such rotationally symmetric oligomers is strongly modified by the interplay between the polarization properties of the CVB and interparticle coupling. We find that the oligomers with radially oriented nanorods exhibit small coupling effects. In contrast, we find that the oligomers with azimuthally oriented nanorods exhibit large coupling effects that lead to silencing of SHG from the whole structure. Our experimental results are in very good agreement with numerical calculations based on the boundary element method. The work describes a new route for studying coupling effects in complex arrangements of nano-objects and thereby for tailoring the efficiency of nonlinear optical effects in such structures.

AB - Most beta-d-xylosides with hydrophobic aglycones are nontoxic primers for glycosaminoglycan assembly in animal cells. However, when Ebselen was conjugated to d-xylose, d-glucose, d-galactose, and d-lactose (8A-D), only Ebselen beta-d xyloside (8A) showed significant cytotoxicity in human cancer cells. The following facts indicated that the aglycone Ebselen and beta-d-xyloside primed glycosaminoglycans co-contributed to the observed cytotoxicity: 1. Ebselen induced S phase cell cycle arrest, whereas 8A induced G2/M cell cycle arrest; 2. 8A augmented early and late phase cancer cell apoptosis significantly compared to that of Ebselen and 8B-D; 3. Both 8A and phenyl-beta-d-xyloside primed glycosaminoglycans with similar disaccharide compositions in CHO-pgsA745 cells; 4. Glycosaminoglycans could be detected inside of cells only when treated with 8A, indicating Ebselen contributed to the unique property of intracellular localization of the primed glycosaminoglycans. Thus, 8A represents a lead compound for the development of novel antitumor strategy by targeting glycosaminoglycans.

AB - Change of the permanent molecular electric dipole moment, DeltaMU, in a series of nominally centrosymmetric and noncentrosymmteric ferrocene-phenyleneethynylene oligomers was estimated by measuring the two-photon absorption cross-section spectra of the lower energy metal-to-ligand charge-transfer transitions using femtosecond nonlinear transmission method and was found to vary in the range up to 12 D, with the highest value corresponding to the most nonsymmetric system. Calculations of the DeltaMU performed by the TD-DFT method show quantitative agreement with the experimental values and reveal that facile rotation of the ferrocene moieties relative to the organic ligand breaks the ground-state inversion symmetry in the nominally symmetric structures.

AB - Two-dimensional electronic spectroscopy was applied to a variant of the reaction center (RC) of purple bacterium Rhodobacter sphaeroides lacking the primary acceptor ubiquinone in order to understand the ultrafast separation and transfer of charge between the bacteriochlorin cofactors. For the first time, characteristic 2D spectra were obtained for the participating excited and charge transfer states, and the electron-transfer cascade (including two different channels, the P* and B* channels) was fully mapped. By analyzing quantum beats using 2D frequency maps, excited-state vibrational modes at 153 and 33 cm-1 were identified. We speculate that these modes couple to the charge separation (CS) process and collectively optimize the CS and are responsible for the superhigh efficiency.

AB - Group I-II-V-VI semiconducting Cu12- xM xSb4S13 (M = ZnII, CdII, MnII and CuII) substituted tetrahedrite nanostructures remain a new class of multinary materials that have not been widely explored yet. Having different ions, the formation process of these nanostructures always has the possibility of formation of cross nucleations. Minimizing the reaction time, herein, a predominantly thermodynamic control approach is reported, which decouples the quaternary nucleations from their possible cross nucleations. As a consequence, possible cross nucleations were prevented and a series of nearly monodisperse intriguing substituted tetrahedrite nanostructures were formed. The possible LaMer plot for the single- and multimaterial nucleations is also proposed. Further, bandgaps of all of these new materials are calculated, and preliminarily, the applicability of these materials is tested for photoelectrochemical water splitting.

AB - This work reports a cobalt(II)/ N-hydroxyphthalimide (NHPI)-catalyzed cross dehydrogenative oxidative coupling of N-aryl tetrahydroisoquinolines with various pro-nucleophiles, such as indoles, nitroalkanes, and trialkylphosphites, active methylene compounds, and other nucleophiles, such as cyanide (ethyl cyanoformate), at room temperature under aerobic conditions. The present protocol is operationally simple and can be carried out without photoirradiation and under peroxide-free conditions, even on a gram scale, to afford the products in good to excellent yields. On the basis of mass spectrometry and control experiments, a catalytic reaction pathway has been proposed.

AB - Hexaoxatriphenylene, a scaffold linker often utilized in building covalent organic frameworks, is shown to be electroactive and a useful entity to build light energy-harvesting donor-acceptor systems. To demonstrate this, new donor acceptor conjugates have been synthesized by employing BODIPY as a sensitizer. Excited-state electron transfer leading to high-energy charge-separated states, useful to drive energy-demanding photocatalytic reactions, from the electron-rich hexaoxatriphenylene to 1BODIPY*, in the synthesized tri-BODIPY hexaoxatriphenylene "paddle-wheel" conjugates, has been successfully demonstrated using femtosecond transient absorption spectroscopy. The measured rate of charge separation was in the range of ~3-10 * 1011 s-1, revealing ultrafast charge separation. PMID- 29584945 TI - Diffusivity of Carbon Dioxide in Aqueous Solutions under Geologic Carbon Sequestration Conditions. AB - Accurate assessment of the long-term security of geologic carbon sequestration requires knowledge of the mobility of carbon dioxide in brines under pressure and temperature conditions that prevail in subsurface aquifers. Here, we report Raman spectroscopic measurements of the rate of CO2 diffusion in water and brines as a function of pressure, salinity, and concentration of CO2. In pure water at 50 +/- 2 degrees C and 90 +/- 2 bar, we find the diffusion coefficient, D, to be (3.08 +/- 0.03) * 10-9 m2/s, a value that is consistent with a recent microfluidic study but lower than earlier PVT measurements. Under reservoir conditions, salinity affects the mobility of CO2 significantly and D decreased by 45% for a 4 M solution of NaCl. We find significant differences of diffusivity of CO2 in brines (0-4 M NaCl), in both the absolute values and the trend compared to the Stokes-Einstein prediction under our experimental conditions. We observe that D decreases significantly at the high CO2 concentrations expected in subsurface aquifers (~15% reduction at 0.55 mol/kg of CO2) and provides an empirical correction to the commonly reported D values that assume a tracer concentration dependence on diffusivity. PMID- 29584946 TI - A Second Glass Transition in Pressure Collapsed Type II Clathrate Hydrates. AB - Type II clathrate hydrates (CHs) M.17 H2O, with M = tetrahydrofuran (THF) or 1,3 dioxolane, are known to collapse, or amorphize, on pressurization to ~1.3 GPa in the temperature range 77-140 K. On heating at 1 GPa, these pressure-amorphized CH states show a weak, stretched sigmoid-shaped, heat-capacity increase because of a glass transition. Here we use thermal conductivity and heat capacity measurements to show that also type II CH with M = cyclobutanone (CB) collapses on isothermal pressurization and undergoes a similar, weak, glass transition upon heating at 1 GPa. Furthermore, we reveal for both THF CH and CB CH a second, much more pronounced, glass transition at temperatures above the thermally weak glass transition on heating in the 0.2-0.7 GPa range. This result suggests the general occurrence of two glass transitions in water-rich (94 mol %) pressure-collapsed CHs. Because of a large increase in dielectric permittivity concurrently as the weak heat capacity increase, the first glass transition must be due to kinetic unfreezing of water molecules. The thermal features of the second glass transition, measured on isobaric temperature cycling, are typical of a glass liquid-glass transition, which suggests that pressure-amorphized CHs transform reversibly to liquids.

AB - The dispersion of nanoparticles having different size-, shape-, and composition dependent properties is an exciting approach to design and synthesize multifunctional materials and devices. This work shows a detailed investigation of the preparation and properties of free-standing nanocomposite films based on cellulose nanocrystals (CNC) loaded with three different types of metal nanoparticles. CNC-based nanocomposites having zinc oxide (ZnO), titanium dioxide (TiO2), and silver oxide (Ag2O) have been obtained through evaporation-induced self-assembly (EISA) in acqueous solution. Morphological and optical characteristics, chemical properties, wettability, and antimicrobial assays of the produced films were conducted. Furthermore, disintegrability in composting condition of CNC based nanocomposites was here investigated for the first time. The morphological observations revealed the formation of a chiral nematic structure with uniformly distributed nanoparticles. The bionanocomposite films based on the metal nanoparticles had effective antimicrobial activity, killing both Escherichia coli RB ( E. coli RB) and Staphylococcus aureus 8325-4 ( S. aureus 8325-4). The simplicity method of film preparation, the large quantity of cellulose in the world, and the free-standing nature of the nanocomposite films offer highly advantageous characteristics that can for the new development of multifunctional materials. PMID- 29584948 TI - Air-Stable Room-Temperature Mid-Infrared Photodetectors Based on hBN/Black Arsenic Phosphorus/hBN Heterostructures. AB - Layered black phosphorus (BP) has attracted wide attention for mid-infrared photonics and high-speed electronics, due to its moderate band gap and high carrier mobility. However, its intrinsic band gap of around 0.33 electronvolt limits the operational wavelength range of BP photonic devices based on direct interband transitions to around 3.7 MUm. In this work, we demonstrate that black arsenic phosphorus alloy (b-As xP1- x) formed by introducing arsenic into BP can significantly extend the operational wavelength range of photonic devices. The as fabricated b-As0.83P0.17 photodetector sandwiched within hexagonal boron nitride (hBN) shows peak extrinsic responsivity of 190, 16, and 1.2 mA/W at 3.4, 5.0, and 7.7 MUm at room temperature, respectively. Moreover, the intrinsic photoconductive effect dominates the photocurrent generation mechanism due to the preservation of pristine properties of b-As0.83P0.17 by complete hBN encapsulation, and these b-As0.83P0.17 photodetectors exhibit negligible transport hysteresis. The broad and large photoresponsivity within mid-infrared resulting from the intrinsic photoconduction, together with the excellent long term air stability, makes b-As0.83P0.17 alloy a promising alternative material for mid-infrared applications, such as free-space communication, infrared imaging, and biomedical sensing. PMID- 29584949 TI - A Chemical Probe for Protein Crotonylation. AB - Protein lysine crotonylation has emerged as an important post-translational modification (PTM) in the regulation of gene transcription through epigenetic mechanisms. Here we introduce a chemical probe, based on a water-soluble phosphine warhead, which reacts with the crotonyl modification. We show that this reagent is complementary to antibody-based tools allowing detection of endogenous cellular proteins such as histones carrying the crotonylation PTM. The tool is also used to show that the histone acylation activity of the transcriptional coactivator, p300, can be activated by pre-existing lysine crotonylation through a positive feedback mechanism. This reagent provides a versatile and sensitive probe for the analysis of this PTM. PMID- 29584950 TI - Does Soluble Mn(III) Oxidant Formed in Situ Account for Enhanced Transformation of Triclosan by Mn(VII) in the Presence of Ligands? AB - In previous studies, we interestingly found that several ligands (e.g., pyrophosphate, nitrilotriacetate, and humic acid) could significantly accelerate the oxidation rates of triclosan (TCS; the most widely used antimicrobial) by aqueous permanganate (Mn(VII)) especially at acid pH, which was ascribed to the contribution of ligand-stabilized Mn(III) (defined Mn(III)L) formed in situ as a potent oxidant. In this work, it was found that the oxidation of TCS by Mn(III)L resulted in the formation of dimers, as well as hydroxylated and quinone-like products, where TCS phenoxy radical was likely involved. This transformation pathway distinctly differed from that involved in Mn(VII) oxidation of TCS, where 2,4-dichlorophenol (DCP) was the major product with a high yield of ~80%. Surprisingly, we found that the presence of various complexing ligands including pyrophosphate, nitrilotriacetate, and humic acid, as well as bisulfite slightly affected the yields of DCP, although they greatly enhanced the oxidation kinetics of TCS by Mn(VII). This result could not be reasonably explained by taking the contribution of Mn(III)L into account. Comparatively, the degradation of TCS by manganese dioxide (MnO2) was also greatly enhanced in the presence of these ligands with negligible formation of DCP, which could be rationalized by the contribution of Mn(III)L. In addition, it was demonstrated that DCP could not be generated from Mn(VII) oxidation of unstable phenoxy radical intermediates and stable oxidation products formed from TCS by Mn(III)L. These findings indicate that manganese intermediates other than Mn(III) are likely involved in the Mn(VII)/TCS/ligand systems responsible for the high yields of DCP product.

AB - We report here a kinetic study on the thermal equilibrium process between the biradical form and the quinoidal form starting from the singlet biradical form alone. A photochromic phenoxyl-imidazolyl radical complex repeatedly generates biradical species upon UV light irradiation, and the following thermal equilibrium process responsible for valence isomerization from the open-shell singlet biradical to the closed-shell quinoidal form is observed in the microsecond time region. The thermodynamic parameters for the equilibrium process were determined for the first time by nanosecond laser flash photolysis. We also found that visible-light excitation to the equilibrium state causes valence photoisomerization from the quinoidal to the biradical form, which returns thermally to the quinoidal form. PMID- 29584952 TI - Pesticide Risks in Small Streams-How to Get as Close as Possible to the Stress Imposed on Aquatic Organisms. AB - The risks associated with pesticides in small streams remain poorly characterized. The challenges reside in understanding the complexities of (1) the highly dynamic concentration profiles of (2) several hundred active substances with (3) differing seasonality. The present study addressed these three challenges simultaneously. Five small streams in catchments under intensive agricultural land use were sampled using half-day composite samples from March to August 2015. Of 213 active substances quantified using liquid chromatography-high resolution mass spectrometry, a total of 128 was detected at least at one of the sites. Ecotoxicological acute and/or chronic quality criteria were exceeded for a total of 32 different active substances. The evaluation of risks over time revealed the necessity to evaluate the sequences of different active substances that are imposed on aquatic organisms. In contrast, a substance-specific perspective provides only a very limited assessment. Scenarios for reduction of either temporal resolution, number of substances or seasonal coverage were defined. It could be shown that risks can be underestimated by more than a factor of 10 in vulnerable catchments and that an increased temporal resolution is essential to cover acute risks but that a focused selection of substances is a possibility to reduce expenditures.

AB - Pharmaceutical scientists are increasingly interested in amorphous drug formulations especially because of their higher dissolution rates. Consequently, the thorough characterization and analysis of these formulations are becoming more and more important for the pharmaceutical industry. Here, fluorescence lifetime-imaging microscopy (FLIM) was used to monitor the crystallization of an amorphous pharmaceutical compound, indomethacin. Initially, we identified different solid indomethacin forms, amorphous and gamma- and alpha-crystalline, on the basis of their time-resolved fluorescence. All of the studied indomethacin forms showed biexponential decays with characteristic fluorescence lifetimes and amplitudes. Using this information, the crystallization of amorphous indomethacin upon storage in 60 degrees C was monitored for 10 days with FLIM. The progress of crystallization was detected as lifetime changes both in the FLIM images and in the fluorescence-decay curves extracted from the images. The fluorescence lifetime amplitudes were used for quantitative analysis of the crystallization process. We also demonstrated that the fluorescence-lifetime distribution of the sample changed during crystallization, and when the sample was not moved between measuring times, the lifetime distribution could also be used for the analysis of the reaction kinetics. Our results clearly show that FLIM is a sensitive and nondestructive method for monitoring solid-state transformations on the surfaces of fluorescent samples.

AB - Two biological activities of butyrate in the colon (suppression of proliferation of colonic epithelial stem cells and inflammation) correlate with inhibition of the activity of histone deacetylases. Cellular and biochemical studies of molecules similar in structure to butyrate, but different in molecular details (functional groups, chain-length, deuteration, oxidation level, fluorination, or degree of unsaturation), demonstrated that these activities were sensitive to molecular structure, and were compatible with the hypothesis that butyrate acts by binding to the Zn2+ in the catalytic site of histone deacetylases. Structure activity relationships drawn from a set of 36 compounds offer a starting point for the design of new compounds targeting the inhibition of histone deacetylases. The observation that butyrate was more potent than other short-chain fatty acids is compatible with the hypothesis that crypts evolved (at least in part), to separate stem cells at the base of crypts from butyrate produced by commensal bacteria. PMID- 29584956 TI - Interface Engineering in Quantum-Dot-Sensitized Solar Cells. AB - The unique properties of II-VI semiconductor nanocrystals such as superior light absorption, size-dependent optoelectronic properties, solution processability, and interesting photophysics prompted quantum-dot-sensitized solar cells (QDSSCs) as promising candidates for next-generation photovoltaic (PV) technology. QDSSCs have advantages such as low-cost device fabrication, multiple exciton generation, and the possibility to push over the theoretical power conversion efficiency (PCE) limit of 32%. In spite of dedicated research efforts to enhance the PCE, optimize individual solar cell components, and better understand the underlying science, QDSSCs have unfortunately not lived up to their potential due to shortcomings in the fabrication process and with the QDs themselves. In this feature article, we briefly discuss the QDSSC concepts and mechanisms of the charge carrier recombination pathways that occur at multiple interfaces, viz., (i) metal oxide (MO)/QDs, (ii) MO/QDs/electrolyte, and (iii) counter electrode (CE)/electrolyte. The rational strategies that have been developed to minimize/block these charge recombination pathways are elaborated. The article concludes with a discussion of the present challenges in fabricating efficient devices and future prospects for QDSSCs.

AB - A new FeCl2- and DTBP (di- tert-butyl peroxide)-promoted oxidative ring-opening and cyclization of methylenecyclopropanes with aldehydes for the synthesis of 2 acyl-3,4-dihydronaphthalenes is presented. This oxidative cyclization reaction proceeds via a radical addition, ring-opening, and cyclization sequence facilitated by a Lewis acid, and it offers a practical and straightforward route for the oxidative cyclization of methylenecyclopropanes with an aromatic carbon and a C(sp2)-H bond by simultaneously forming two new carbon-carbon bonds.

AB - Radical cyclization represents a powerful strategy for construction of ring structures. Traditional radical cyclization, which is based on radical addition as the key step, necessitates the use of unsaturated substrates. Guided by the concept of metalloradical catalysis, a different mode of radical cyclization that can employ saturated C-H substrates is demonstrated through the development of a Co(II)-based system for catalytic activation of aliphatic diazo compounds for enantioselective radical alkylation of various C(sp3)-H bonds. It allows for efficient construction of chiral pyrrolidines and other valuable 5-membered cyclic compounds. This alternative strategy of radical cyclization provides a new retrosynthetic paradigm to prepare five-membered cyclic molecules from readily available open-chain aldehydes through the union of C-H and C=O elements for C-C bond formation. PMID- 29585642 TI - How to Detect a Cuckoo Egg: A Signal-Detection Theory Model for Recognition and Learning. AB - This article presents a model of egg rejection in cases of brood parasitism. The model is developed in three stages in the framework of signal-detection theory. We first assume that the behavior of host females is adapted to the relevant parameters concerning the appearance of the eggs they lay. In the second stage, we consider the possibility that females make perceptual errors. In the final stage, females must learn to recognize their own eggs through an imprinting process. The model allows us to make a number of predictions concerning the egg types that should be rejected in different circumstances: egg rejection should increase as the parasitism rate increases and egg mimicry deteriorates; host females' erroneous ejection of their own eggs should be expected for intermediate levels of egg mimicry but not for very good or very poor mimicry; host females would benefit most from learning to recognize their own eggs when individual variability in egg characteristics is much lower than the population variability; and, when egg mimicry is poor or individual variability is very low, females should attempt to imprint on the first egg they lay, before they can be parasitized, but, when mimicry is good and individual variability is relatively high, females must use an extended learning phase. The model provides a framework to study how the enigmatic acceptance of parasitic eggs can be explained by adaptive discrimination mechanisms. PMID- 29585643 TI - Spatial Moment Equations for Plant Competition: Understanding Spatial Strategies and the Advantages of Short Dispersal. AB - A plant lineage can compete for resources in a spatially variable environment by colonizing new areas, exploiting resources in those areas quickly before other plants arrive to compete with it, or tolerating competition once other plants do arrive. These specializations are ubiquitous in plant communities, but all three have never been derived from a spatial model of community dynamics-instead, the possibility of rapid exploitation has been either overlooked or confounded with colonization. We use moment equations, equations for the mean densities and spatial covariance of competing plant populations, to characterize these strategies in a fully spatial stochastic model. The moment equations predict endogenous spatial pattern formation and the efficacy of spatial strategies under different conditions. The model shows that specializations for colonization, exploitation, and tolerance are all possible, and these are the only possible spatial strategies; among them, they partition all of the endogenous spatial structure in the environment. The model predicts two distinct short-dispersal specializations where parents disperse their offspring locally, either to exploit empty patches quickly or to fill patches to exclude competitors.

PMID- 29585646 TI - Allometry of Constitutive Defense: A Model and a Comparative Test with Tree Bark and Fire Regime. AB - In a simulation model, the relative advantage of negative versus positive allometry of defense, that is, early versus delayed defensive investment, depends on the forms of the relationships between body size and growth, body size and mortality deterrence, and defense size and mortality deterrence. Positive allometry is favored by strongly sigmoidal growth, a strongly convex body size/deterrence relationship, and a concave defense-size/deterrence relationship. Rapid early growth, a weakly convex body-size/deterrence relationship, and a convex defense-size/deterrence relationship favor negative allometry. The model is tested by comparing, among Pinus and Quercus species, measured intraspecific bark allometry with a predicted ranking of bark allometry along the negative positive continuum. The ranking is based on the forms of body-size/deterrence and defense-size/deterrence relationships expected in each species' typical habitat given the fire regime and canopy type. This predicted ranking of bark allometry is significantly correlated with measured bark allometry. Negative bark allometry and thick sapling bark are associated with habitats characterized by frequent low intensity fire and relatively open canopies. Fire-resilient Pinus spp. and species of infrequently burned, closed-canopy forests tend to have positive bark allometry and thin sapling bark. PMID- 29585647 TI - Temporal Variation in Danger Drives Antipredator Behavior: The Predation Risk Allocation Hypothesis. AB - The rapid response of animals to changes in predation risk has allowed behavioral ecologists to learn much about antipredator decision making. A largely unappreciated aspect of such decision making, however, is that it may be fundamentally driven by the very thing that allows it to be so readily studied: temporal variation in risk. We show theoretically that temporal variability in risk leaves animals with the problem of allocating feeding and antipredator efforts across different risk situations. Our analysis suggests that an animal should exhibit its greatest antipredator behavior in high-risk situations that are brief and infrequent. An animal should also allocate more antipredator effort to high-risk situations and more feeding to low-risk situations, with an increase in the relative degree of risk in high-risk situations. However, the need to feed leaves an animal with little choice but to decrease its allocation of antipredator effort to high-risk situations as they become more frequent or lengthy; here, antipredator effort in low-risk situations may drop to low levels as an animal allocates as much feeding as possible to brief periods of low risk. These conclusions hold under various scenarios of interrupted feeding, state dependent behavior, and stochastic variation in risk situations. Our analysis also suggests that a common experimental protocol, in which prey animals are maintained under low risk and then exposed to a brief "pulse" of high risk, is likely to overestimate the intensity of antipredator behavior expected under field situations or chronic exposure to high risk. PMID- 29585648 TI - Balanced Polymorphisms and the Evolution of Dominance. AB - We explore the evolution of dominance at polymorphisms maintained either by overdominant selection or by migration-selection balance. At such balanced polymorphisms, heterozygotes remain at appreciable frequencies over long periods of time, allowing extensive modification of dominance to occur. The strength of selection favoring a modifier of dominance is roughly proportional to the probability that a modifier allele is found in a heterozygote at the locus subject to balancing selection times the heterozygote fitness increase caused by the modifier. Using a two-locus model, we elucidate the interesting ways in which recombination and migration cause departures from this rough expectation. For example, with overdominance, a genetic association with the rarest allele favors a modifier that increases heterozygote fitness because the modifier occurs more often in heterozygotes. With migration-selection balance, dominance evolves more readily in patches experiencing the strongest selection. We also find that, while there are more heterozygotes in sink populations (which have higher rates of immigration than emigration), selection for dominance in sink and source populations is nearly equal because sink populations make a lower genetic contribution to future generations. We conclude that the evolution of dominance is likely to occur whenever polymorphism is maintained by either overdominance or migration. PMID- 29585730 TI - Musculoskeletal Screening Tests and Bony Hip Morphology Cannot Identify Male Professional Soccer Players at Risk of Groin Injuries: A 2-Year Prospective Cohort Study. AB - BACKGROUND: Musculoskeletal hip/groin screening tests are commonly performed to detect at-risk individuals. Bony hip morphology is considered a potential intrinsic risk factor but has not been examined prospectively. PURPOSE: To evaluate the association between intrinsic risk factors identified from musculoskeletal and radiographic screening tests and hip/groin injuries leading to time loss from training and/or match play in professional male soccer players. STUDY DESIGN: Prospective cohort study; Level of evidence, 2. METHODS: Male professional soccer players, aged >=18 years, underwent screening specific for hip/groin pain during 2 consecutive seasons of the Qatar Stars League. The screening battery included pain provocation, range of motion, and strength tests as well as a hip radiographic examination. The radiographic examination included an anteroposterior pelvic view and 45 degrees Dunn view, with bony hip morphology determined using quantitative methods. Time-loss (>=1 day) hip/groin injuries and individual player exposure (training and match play) were recorded prospectively, and injuries were categorized as adductor-related, inguinal related, iliopsoas-related, pubic-related, or hip-related groin pain, or "other," as recommended in the Doha agreement. We calculated hazard ratios (HRs) from univariate and multivariate Cox regression models to assess the relationship between potential risk factors and hip/groin injuries. RESULTS: There were 438 players, completing 609 player seasons, and 113 hip/groin injuries that met the criteria for inclusion, with 85 injuries categorized as adductor-related. The proportion of players with bony morphological variants was the following: cam, 71%; pincer, 5%; and acetabular dysplasia, 13%. Previous hip/groin injuries (HR, 1.8; 95% CI, 1.2-2.7) and eccentric adduction strength were associated with the risk of hip/groin injuries. Higher (>1 SD above the mean) than normal eccentric adduction strength was associated with an increased risk for all hip/groin injuries (HR, 1.6; 95% CI, 1.0-2.5). Lower (<1 SD below the mean) than normal eccentric adduction strength was associated with an increased risk for adductor related injuries (HR, 1.7; 95% CI, 1.0-3.0). No other musculoskeletal screening test or bony hip morphology variables were associated with the injury risk. CONCLUSION: Previous groin injuries and eccentric adduction strength were associated with the risk of groin injuries. However, these associations were not strong enough to identify an "at-risk" individual, and therefore, musculoskeletal screening tests were not useful to dictate individualized prevention strategies. Bony hip morphology was not associated with the risk of groin injuries. PMID- 29585797 TI - Erratum. PMID- 29585968 TI - Inequality and the Directionality of History. AB - I argue that history is genealogy and succession in an economic context of interactions among participants. Inequality is a ubiquitous property of economic interaction among responsive, metabolizing entities. The prevailing party tends to be larger, to have a higher productivity or metabolism, to engage in a larger number of interactions, and to perform more functions at a higher level. The crucial economic consequence of inequality is that prevailing entities and the conditions they create disproportionately influence the economy as a whole. This leads to a pervasive increase in energy flux, both globally and per capita, among economic dominants, observable in the history of life as well as in the development of the human economy. Unpredictable disturbances such as mass extinctions temporarily reverse this trend. Comparative studies of the biotas of islands and of large land masses point to limitations on the evolution of energy intensive dominants. Because entities with a large economic domain typically restrict rather than eliminate subordinates, the trend toward increasing energy flux will rarely be expressed within individual clades. History's directionality is imposed by effects of energy-intensive dominants on the distribution and characteristics of all other participants in the economies they help to fashion. PMID- 29585927 TI - Neutrophil activation in response to monomeric myeloperoxidase. AB - Myeloperoxidase (MPO) is an oxidant-producing enzyme that can also regulate cellular functions via its nonenzymatic effects. Mature active MPO isolated from normal human neutrophils is a 145 kDa homodimer, which consists of 2 identical protomers, connected by a single disulfide bond. By binding to CD11b/CD18 integrin, dimeric MPO induces neutrophil activation and adhesion augmenting leukocyte accumulation at sites of inflammation. This study was performed to compare the potency of dimeric and monomeric MPO to elicit selected neutrophil responses. Monomeric MPO (hemi-MPO) was obtained by treating the dimeric MPO by reductive alkylation. Analysis of the crucial signal transducer, intracellular Ca2+, showed that dimeric MPO induces Ca2+ mobilization from the intracellular calcium stores of neutrophils and influx of extracellular Ca2+ whereas the effect of monomeric MPO on Ca2+ increase in neutrophils was less. It was also shown that monomeric MPO was less efficient than dimeric MPO at inducing actin cytoskeleton reorganization, cell survival, and neutrophil degranulation. Furthermore, we have detected monomeric MPO in the blood plasma of patients with acute inflammation. Our data suggest that the decomposition of dimeric MPO into monomers can serve as a regulatory mechanism that controls MPO-dependent activation of neutrophils and reduces the proinflammatory effects of MPO. PMID- 29585969 TI - Sperm Displacement in the Yellow Dung Fly, Scatophaga stercoraria: An Investigation of Male and Female Processes. AB - Despite the ubiquity with which patterns of sperm utilization have been studied, the mechanisms underlying fertilization in insects are far from clear. One well studied system is the yellow dung fly, in which the last male's ejaculate is thought to displace rival sperm from the female's sperm stores. Here we follow the movement of the copulating male's ejaculate through the female's reproductive tract using males labeled with different radioisotopes. We find that males ejaculate into the bursa copulatrix and that male-1 sperm are displaced from the spermathecae during copulation. The increase in male-2 ejaculate in the spermathecae matches the pattern of male-2 fertilization gain, indicating that only spermathecal sperm are utilized at fertilization. Previously we have analyzed this system with a direct model of sperm displacement in which the male displaces rival sperm from the spermathecae. The data, and morphology of the female, clearly preclude such a mechanism. Here we contrast this model with a new indirect model, in which the female facilitates displacement by exchange of sperm from the bursa copulatrix to the spermathecae. The two models give equivalent fits to the observed sperm utilization patterns because the rate of sperm transfer into the bursa copulatrix greatly exceeds the rate of sperm exchange with the spermathecae so that the concentration of the first male's sperm in the bursa remains considerably lower than that of the second male. These analyses provide a quantitative attempt to incorporate female processes into the analysis of sperm utilization patterns in insects. PMID- 29585970 TI - Learning, Host Fidelity, and the Stability of Host-Parasitoid Communities. AB - Simple models of host-parasitoid interactions show that a polyphagous parasitoid tends to drive extinct all but the most fecund of its hosts. Coexistence requires a mechanism by which hosts with lower fecundity can increase when rare. We explore how recently discovered parasitoid learning behavior can contribute to species coexistence. On emergence as adults, parasitoids learn chemical cues associated with their natal host and hence are more likely to locate and to oviposit in hosts of the same species. For two models incorporating different assumptions about parasitoid searching, we derive conditions for the strength of host fidelity that permits a feasible multihost equilibrium and argue that this equilibrium is stable whenever the corresponding single-host equilibria are stable. PMID- 29585971 TI - Accounting for Mode of Speciation Increases Power and Realism of Tests of Phylogenetic Asymmetry. AB - Tree symmetry is crucial to the investigation of evolutionary processes, particularly adaptive radiation. Testing a phylogeny for asymmetry requires a null model; the most accepted to date is the Markov (random branching) model, which assumes that speciation is instantaneous and that all species have an equal and independent chance of speciation. Such assumptions result in a high probability of asymmetric trees (which makes tests of asymmetry weak) and may be unrealistic. Subsequent modification of this model incorporated parameters conforming to diversification by peripheral-isolates speciation, producing trees that were more symmetric than those generated under the Markov model. Our reanalysis of these data, and remodeling with a greater number of replicates, shows that differences between the original Markov and modified models may have been exaggerated: different measures show that initial increases in tree symmetry under peripheral-isolates speciation are transient; symmetry on small scales actually decreases when the process of speciation requires a significant fraction of the average time between speciation events. The peripheral-isolates mode of speciation is compared with a vicariant mode, which shows steadily increasing symmetry on all scales. In cases where vicariant speciation has been common, use of a vicariant-based null model in tests of phylogenetic asymmetry is appropriate and will provide greater statistical power. PMID- 29585972 TI - The Influence of Plant and Herbivore Characteristics on the Interaction between Induced Resistance and Herbivore Population Dynamics. AB - Induced plant resistance may contribute to regulating or driving fluctuations in insect herbivore populations. However, experimental demonstrations of induced resistance affecting long-term herbivore population dynamics are lacking, and few models find that induced resistance drives cycles in herbivore populations. Here a simulation model is used to explore the influence of characteristics of the plant-herbivore system on the likelihood that induced resistance can regulate or drive cycles in herbivore populations. Results of this model suggest that induced resistance may cause fluctuations in herbivore populations under more conditions than previously thought. The model incorporates parameters for the timing and strength of induced resistance and for herbivore mobility and host-plant selectivity. Results are presented for two configurations of the model: forest (many herbivore generations per plant generation) and crop (few herbivore generations per plant generation). In simulations of this model, induced resistance in the absence of other density-dependent factors can regulate herbivore populations. Induced resistance can also drive fluctuations in herbivore populations when there is a time lag between damage and the onset of induced resistance. The time lag required to cause fluctuations depends on characteristics such as the strength of induced resistance and the mobility of the herbivore. PMID- 29585973 TI - Predator Migration Decisions, the Ideal Free Distribution, and Predator-Prey Dynamics. AB - The aim of the present work is to analyze the influence of optimal predator emigration decisions that can lead to the ideal free distribution (IFD) on the stability of predator-prey systems. The assumption of optimal decisions is then relaxed to analyze the possible influence of different degrees of deviation from the IFD. The first migration rule we analyze is based on the marginal-value theorem and assumes perfect knowledge of capture rate in the patch of residence and in the environment as a whole. When migration rates are high, this rule leads the predator population to the IFD. The results suggest that under these conditions predator migration plays no major role in the stability of the system. This is so because the systems naturally merge into a single patch. This result is independent of the particular functional response used. The other two rules we analyze take into account lower migration rates, the limitations in making optimal decisions by predators, and the possible constraints in the assessment of intake rate in the different patches. The results suggest that the processes that hinder the convergence of the populations to the IFD might make a major contribution to the stability of the system. PMID- 29585974 TI - Interacting Phenotypes and the Evolutionary Process. II. Selection Resulting from Social Interactions. AB - Social interactions often affect the fitness of interactants. Because of this, social selection has been described as a process distinct from other forms of natural selection. Social selection has been predicted to result in different evolutionary dynamics for interacting phenotypes, including rapid or extreme evolution and evolution of altruism. Despite the critical role that social selection plays in theories of social evolution, few studies have measured the force of social selection or the conditions under which this force changes. Here we present a model of social selection acting on interacting phenotypes that can be evaluated independently from the genetics of interacting phenotypes. Our model of social selection is analogous to covariance models of other forms of selection. We observe that an opportunity for social selection exists whenever individual fitness varies as a result of interactions with conspecifics. Social selection occurs, therefore, when variation in fitness due to interactions covaries with traits, resulting in a net force of selection acting on the interacting phenotypes. Thus, there must be a covariance between the phenotypes of the interactants for social selection to exist. This interacting phenotype covariance is important because it measures the degree to which a particular trait covaries with the selective environment provided by conspecifics. A variety of factors, including nonrandom interactions, behavioral modification during interactions, relatedness, and indirect genetic effects may contribute to the covariance of interacting phenotypes, which promotes social selection. The independent force of social selection (measured as a social selection gradient) can be partitioned empirically from the force of natural selection (measured by the natural selection gradient) using partial regression. This measure can be combined with genetic models of interacting phenotypes to provide insights into social evolution. PMID- 29585975 TI - Reproductive Skew in Multimember Groups. AB - Cooperative societies vary in the extent to which reproduction is skewed toward one or a few socially dominant animals. Many recent models attempt to explain this variation on the basis that a dominant who benefits from the presence of subordinates may offer them incentives, in the form of reproductive opportunities, to remain in the group. While most societies contain multiple members, however, these models have considered only the relationship between a dominant and a single subordinate or have assumed that all subordinates are identical. We develop an incentive-based evolutionary stable strategy model of reproductive skew in three-member groups, in which subordinates may vary in their opportunities for independent reproduction, their contribution to group productivity, and in their relatedness both to the dominant and to one another. Our model demonstrates that the conclusions of two-member models cannot all be generalized to larger groups. For example, relatedness among group members can influence whether or not the dominant does best to offer staying incentives to subordinates in a three-member, but not a two-member, group. Both the degree of skew and group stability depend on the relatedness between subordinates as well as on the relatedness of each to the dominant, and the incentives that each individual subordinate receives are influenced by the traits of the other. Whether such effects increase or decrease skew and group stability depends crucially on whether a third group member increases group productivity to a greater or lesser extent than the first.

AB - Plant defensins are plant antimicrobial peptides that present diverse biological activities in vitro, including the elimination of Leishmania amazonensis. Plant defensins are considered promising candidates for the development of new drugs. This protozoan genus has great epidemiological importance and the mechanism behind the protozoan death by defensins is unknown, thus, we chose L. amazonensis for this study. The aim of the work was to analyze the possible toxic mechanisms of Vu-Defr against L. amazonensis. For analyses, the antimicrobial assay was repeated as previously described, and after 24 h, an aliquot of the culture was tested for viability, membrane perturbation, mitochondrial membrane potential, reactive oxygen species (ROS) and nitric oxide (NO) inductions. The results of these analyses indicated that after interaction with L. amazonensis, the Vu-Defr causes elimination of promastigotes from culture, membrane perturbation, mitochondrial membrane collapse, and ROS induction. Our analysis demonstrated that NO is not produced after Vu-Defr and L. amazonensis interaction. In conclusion, our work strives to help to fill the gap relating to effects caused by plant defensins on protozoan and thus better understand the mechanism of action of this peptide against L. amazonensis. PMID- 29586541 TI - The pathogenicity of Aspergillus fumigatus, drug resistance, and nanoparticle delivery. AB - The genus Aspergillus includes fungal species that cause major health issues of significant economic importance. These microorganisms are also the culprit for production of carcinogenic aflatoxins in grain storages, contaminating crops, and economically straining the production process. Aspergillus fumigatus is a very important pathogenic species, being responsible for high human morbidity and mortality on a global basis. The prevalence of these infections in immunosuppressed individuals is on the rise, and physicians struggle with the diagnosis of these deadly pathogens. Several virulence determinants facilitate fungal invasion and evasion of the host immune response. Metabolic functions are also important for virulence and drug resistance, since they allow fungi to obtain nutrients for their own survival and growth. Following a positive diagnostic identification, mortality rates remain high due, in part, to emerging resistance to frequently used antifungal drugs. In this review, we discuss the role of the main virulence, drug target, and drug resistance determinants. We conclude with the review of new technologies being developed to treat aspergillosis. In particular, microsphere and nanoparticle delivery systems are discussed in the context of improving drug bioavailability. Aspergillus will likely continue to cause problematic infections in immunocompromised patients, so it is imperative to improve treatment options.

AB - We used a system of neighboring small islands with and without the lizard Anolis sagrei to stage a 7-yr experimental study of the effects of an invading species. Lizard propagules were introduced to four islands, randomly selected from eight that lacked lizards naturally. Four other islands where lizards occurred naturally constituted a third treatment. We examined possible lizard indirect effects on the commonest shrub (via its arthropod herbivores), two sizes of aerial arthropods, and hymenopteran parasitoids. Lizards reduced leaf damage; moreover, during the middle years of the experiment, damage was less on introduction islands than on islands having lizards naturally. Lizards increased the number of small aerial arthropods but had no effect on large aerial arthropods; the full effect on small arthropods was only evident near the end of the experiment. Lizard introduction increased the number of hymenopteran parasitoids at the end of the experiment; however, only islands having lizards naturally had significantly more parasitoids than no-lizard islands summed over the long term. In contrast to the indirect effects, the mostly direct effect of lizards on spiders was very strong; introduction transformed spider density to that on natural lizard islands relatively rapidly and monotonically. In addition to demonstrating how an introduced vertebrate predator can affect food webs even down to the producer level, this study illustrates the greater strength and regularity of direct as opposed to indirect effects. PMID- 29586619 TI - Chick Begging Strategies in Relation to Brood Hierarchies and Hatching Asynchrony. AB - Altricial offspring solicit food by begging, and their parents feed them according to begging intensity, which has been shown to be positively related to offspring need. Parent-offspring genetic conflict calls for analyses of evolutionary stability, and various theoretical models have shown that stability is possible in the framework of handicap theory. The models predict that a negative relationship exists between offspring condition and begging and that offspring in poorer condition should be fed preferentially. However, these predictions depend on two unsatisfactory assumptions. First, they assume a monotonically decelerated relation between condition and fitness (this function is more likely to be sigmoid); second, they ignore physical competition between siblings, which is known to be important. We examined the significance of these issues by manipulating hatching asynchrony in broods of starlings Sturnus vulgaris, thus controlling competitive asymmetries between nest mates. We created broods with senior (older) and junior (younger) chicks and control broods with synchronous chicks. In field and laboratory experiments, we found that seniors begged less than juniors and controls, whereas juniors did not differ significantly from controls. However, seniors received more food from their parents and grew better than juniors or controls (hence, they were in better condition). These results violate the predictions of available theoretical models and, together with limitations in the universality of their assumptions, indicate that fundamental aspects of parent-offspring communication are not yet understood. PMID- 29586620 TI - Limiting Similarity, Species Packing, and System Stability for Hierarchical Competition-Colonization Models. AB - Hierarchical competition-colonization models have been used to explain limiting similarities among species, successional dynamics, and species loss under habitat destruction. This class of models assumes that there is an inverse relationship between competitive ability and colonization ability and that competitively superior species exclude competitively inferior species when both occupy the same site. This hierarchical model of performance trade-offs, however, exhibits some unusual behaviors in the high-diversity limit, including infinitesimally close species packing, pathologically slow dynamics, and fundamentally important regularities in trait-abundance relationships. In particular, under the condition of constant mortality across species, a 3/2-power-law relationship emerges between abundance and fecundity under infinite packing (abundance of a species with fecundity f is inversely proportional to f to the 3/2 power). In this article, we explore the high-diversity limit of the hierarchical competition colonization model, with particular emphasis on patterns of species packing, species-abundance relationships, and system stability. Because of the potential for pathologically slow dynamics following perturbations and infinitesimally close species packing in the high-diversity limit for this class of models, the models may need to be modified to include more realistic mechanisms governing the extent and timing of interspecific competitive exclusion in order to effectively capture the structure and dynamics of real-world ecosystems. PMID- 29586621 TI - Seasonal Sex Ratio Trend in the European Kestrel: An Evolutionarily Stable Strategy Analysis. AB - We present an evolutionarily stable strategy (ESS) model to analyze selection on seasonal variation in the brood sex ratio, as observed in several species of raptorial birds. The model is specifically tailored to the life history of the European kestrel, and it reflects the maturation time hypothesis, the idea that a seasonal sex ratio trend has evolved because of sex differences in the dependence of age of first breeding on date of birth. First we show how to derive a fitness function in the context of a seasonal environment. Model parameters are estimated from field data in order to derive quantitative predictions. Since little is known about constraints on sex ratio control in birds, we analyze three scenarios, each corresponding to a different strategy set. We consider a model without constraints on sex ratio control, a model where the sex ratio trend is constrained to be linear, and a mechanistic model incorporating a plausible mechanism of sex ratio control in birds. One of the models yields an ESS sex ratio trend that closely resembles the trend observed in the field. However, the predictions are very sensitive to the choice of strategy set. Moreover, the selective forces generated by sex differences in maturation are rather weak. In fact, the mechanistic model shows that seemingly negligible costs of sex ratio control may be sufficient to overcome the adaptive value of adjusting the sex ratio. PMID- 29586622 TI - Sperm Digestion and Reciprocal Sperm Transfer Can Drive Hermaphrodite Sex Allocation to Equality. AB - The intensity of sperm competition determines how much reproductive effort should be invested in sperm. One important factor affecting sperm competition in internally fertilizing organisms is the mating frequency of females, since it determines the extent of competition between ejaculates. In simultaneous hermaphrodites, energy spent on sperm has to be traded off against energy expended on ova production. By extending an existing model, we consider how the number of matings affects sperm competition and, thus, sex allocation in internally fertilizing simultaneous hermaphrodites. We then go on to explore the consequences of two common characteristics of hermaphroditic mating systems, namely, sperm digestion and reciprocal insemination. Since sperm digestion reduces the competitive ability of a given ejaculate, it selects for increased sperm investment. As a result, the amount of sperm digested and male allocation can enter a coevolutionary cycle in which both will increase up to the point of equal investment in male and female gametes and in high rates of digestion. Because of this high degree of sperm digestion, fitness through the male function becomes more dependent on the amount of resources invested in sperm than on the number of matings. As a result, sperm digestion reduces Bateman's principle. Hence, hermaphrodites with sperm digestion should be less likely to display traits that increase the number of matings. Once ejaculates are large and costly, animals insisting on reciprocal sperm transfer will be favored since they receive some compensation for their investment. Under reciprocity, an even higher investment in sperm is favored. This is the result of the compensation received in the form of the partner's ejaculate and a nuptial gift effect by increasing a partner's production of eggs. PMID- 29586623 TI - Timing of Estrus in Fallow Deer Is Adjusted to the Age of Available Mates. AB - The ability to manipulate the timing of ovulation should be a tool available to females during their choice of mates. Females should advance estrus when preferred males are available and delay estrus when only nonpreferred males are available. However, ovulation in some female mammals can be induced by the presence of males. Female estrus could then be either a result of a better stimulus provided by the preferred male or simply manipulation of estrus by the female to reflect her preference. Evidence is therefore required that female estrus coincides with the availability of preferred mating partners, that females actively choose among males, that avoidance of nonpreferred males results in a cost, and that nonpreferred males are in fact capable of reproduction. We observed two experimental groups of fallow deer, one with only socially mature males, and one with subadult but physiologically mature males. Females with mature males conceived earlier (13 of 15 gave birth) than females with subadult males. The former also conceived earlier than they did in the previous year, whereas the latter conceived later (13 of 14 gave birth) than in the previous year. Females avoided subadults more than mature males, and they lost more weight than females with mature males. Because subadult males are capable of reproduction, females not reproducing with them incur two costs: energetic loss and delayed reproduction. Given these costs, we suggest that females receive a benefit from not responding to the advances of young males that would outweigh these costs. This benefit may be to adjust ovulation to the availability of preferred mates. PMID- 29586624 TI - Does Body Size Optimization Result in Skewed Body Size Distribution on a Logarithmic Scale? PMID- 29586625 TI - The Evolution of Costly Resistance in Host-Parasite Systems. AB - Pairwise invadability analysis is used to examine the evolutionary dynamics of host resistance to microparasitic infection. A continuum of strains of the host differs in susceptibility to infection, with less susceptible strains paying a cost resulting in a lower intrinsic growth rate. With a combination of analytical and graphical pairwise invadability analysis, we show that the evolutionary outcome depends crucially on the shape of the constraint function between resistance and its assumed cost in intrinsic growth rates. When resistance is increasingly costly, a single evolutionarily stable strategy is predicted. Alternatively, with decreasingly costly resistance, we find that the hosts tend to be maximally resistant or not at all resistant. There are conditions under which dimorphism of both these types exists but intermediate resistances do not occur. Independently of the trade-off function used, we are always more likely to get resistant strains of the host when the carrying capacity of the host is high. The pathogenicity of the parasite is also important in determining the likelihood and degree of resistance. PMID- 29586706 TI - Exploring the Physiological Basis of Costs of Herbicide Resistance in Arabidopsis thaliana. AB - For some resistance traits identified in crop and weed species, plant physiologists have detailed knowledge of the mechanism of gene action that distinguishes the physiology of resistant and susceptible genotypes. Such information could be useful to those evolutionary biologists interested in coupling the genetics and physiology of resistance mutations with data on the relative fitness of resistant and susceptible genotypes. In previous work, we have shown that the lifetime seed production of chlorsulfuron-resistant Arabidopsis thaliana was substantially lower than that of susceptible plants, and here we explore potential physiological reasons for the fitness reduction. In addition, we highlight several methodological issues that are essential when using transgenic technology to explore fitness trade-offs. PMID- 29586707 TI - Mechanistic Analysis of Natural Selection and a Refinement of Lack's and Williams's Principles. AB - Results from several physiologically based manipulations were synthesized to investigate two selective trade-offs involving offspring number versus offspring quality and costs of reproduction in an annual lizard Uta stansburiana. Lifetime reproductive success of experimentally size-altered progeny was studied to address the offspring number and offspring quality trade-off. Causes of natural selection on adult reproductive costs were assessed with three complementary manipulations of clutch size, egg size, and total clutch mass. Selective trade offs between offspring size and number arose from two opposing episodes of directional selection. Fecundity selection favored female parents that laid large clutches of small offspring, but fecundity selection was balanced by survival selection that favored large offspring. Thus, the offspring number and quality trade-off had a strong stabilizing effect on mean egg size across generations. However, strength and direction of selection arising from adult reproductive costs varied among years. Because reproductive traits were heritable ([Formula: see text]), selection on adult reproduction led to a large evolutionary response to natural selection. Patterns of selection detected in natural phenotypic variation were largely corroborated by phenotypic manipulations. However, maturational costs of reproduction that were detected with phenotypic manipulations were missed by traditional selection analysis of natural phenotypic variation. PMID- 29586708 TI - Manipulative Approaches to Testing Adaptive Plasticity: Phytochrome-Mediated Shade-Avoidance Responses in Plants. AB - Phenotypic plasticity is often assumed to be adaptive, but this hypothesis has rarely been tested. To support the hypothesis, it is necessary to demonstrate that the phenotype induced in each relevant environment confers high fitness in that environment, relative to alternative phenotypes. Unfortunately, such tests are difficult to perform because plasticity prevents the expression of "inappropriate" phenotypes within each environment. Genetic and physiological manipulation can be used very effectively to extend the range of phenotypes within environments and thus provide powerful tools for testing the adaptive plasticity hypothesis. The expression of specific genes involved in cue perception or signal transduction can be altered by mutation or the introduction of transgenes, thus altering the plastic response of an organism to environmental cues. It is also possible to alter the cue itself or to manipulate the developmental response physiologically so as to obtain alternative phenotypes. The relative fitness of these alternative phenotypes can then be measured in each relevant environment. However, these techniques will be most useful when combined with techniques such as phenotypic selection analysis to identify the specific traits under selection in natural populations. We illustrate these approaches using phytochrome-mediated "shade avoidance" responses in plants as a model system. We review the genetic and physiological mechanisms underlying these responses, illustrate how genetic manipulation can elucidate their adaptive value, and discuss the use of physiological manipulation to measure natural selection on plasticity in the wild. PMID- 29586709 TI - Engineering Candidate Genes in Studies of Adaptation: The Heat-Shock Protein Hsp70 in Drosophila melanogaster. AB - One approach to elucidating the relationships among genes, traits, performance, and fitness is to choose genes of candidate evolutionary interest whose significance is well understood from in vitro and cellular studies and to explore the consequences of manipulating these genes in whole organisms in an evolutionary context. Ongoing research on Hsp70 in Drosophila exemplifies this candidate gene approach. The heat-shock protein Hsp70 was chosen for analysis because its biochemical phenotype (i.e., molecular chaperone activity), regulation, and encoding genes are well understood. Investigation of the thermal environment of Drosophila larvae in the wild and natural Hsp70 expression establishes an ecological context for the candidate gene. Engineering of the hsp70 genes via site-specific homologous recombination, expression off of a heterologous promoter, and expression of an innocuous protein off of the hsp70 promoter show that Hsp70 can be sufficient for a significant component of inducible thermotolerance but can have deleterious consequences. Study of nonengineered variation in Hsp70 expression reveals that the genetically engineered effects have counterparts in nature. Thus, in complementary fashion, both genetic engineering and the more classical approaches of evolutionary biology each contribute essential insights to adaptation. PMID- 29586710 TI - Transgenes in the Analysis of Life Span and Fitness. AB - Drosophila P element-mediated transformation can be used to determine whether and how a specific gene contributes to demographic components of fitness. Motivated by the problem of senescence, researchers have applied this approach to genes thought to affect survival through processes of somatic maintenance. Cu/Zn superoxide dismutase and catalase reduce the flux of reactive oxygen molecules that are thought to be a central cause of aging. EF1alpha is a component of the protein synthesis machine; deterioration of this housekeeping function is a potential contributor to senescence. Molecular chaperones such as the heat shock protein hsp70 are multifunctional molecules that affect a cell's response to acute stress. In some models, senescence results from the cumulative effects of stress, and heat shock proteins may regulate the progress of this deterioration. Transformations with the candidate genes of these proteins were used in independent studies to measure the effect of overexpression on longevity; positive results were reported. Here, I discuss the robustness of these results. I use the studies of superoxide dismutase, catalase, and EF1alpha to illustrate how the mutagenic effects of inserts confound our interpretations. I present new data from a reported study of hsp70 overexpression to show how engineered constructs can be used to overcome mutagenic artifacts through the controlled excision of sequences or alleles. The data for hsp70 provide the first strong molecular evidence that somatic maintenance affects longevity. Finally, future potential uses of transformation with Drosophila are discussed. I consider how metabolic control theory predicts that overexpression of genes for enzymes of intermediary metabolism is not likely to produce analytically useful changes in components of fitness. PMID- 29586711 TI - Adaptation, Exaptation, and Constraint: A Hormonal Perspective. AB - We approach conceptual issues in evolutionary biology from an endocrinological perspective, noting that single hormones typically act on several target tissues and thereby mediate suites of correlated phenotypic traits. When several components of such a suite are beneficial, an important evolutionary question is whether all are adaptations or some are exaptations. The answer may depend on whether the traits arose in response to selection on variation in systemic levels of the hormone on variation in responsiveness of target tissues to invariant levels of the hormone. If the former, selection probably acted directly on fewer than all traits; beneficial traits arising indirectly would be exaptations. In contrast, multiple beneficial traits that arose out of independent changes in target-tissue sensitivity to invariant hormone levels could all be adaptations. Knowledge of specific hormonal mechanisms as well as of historical selective regimes will be necessary to draw such distinctions. Endocrine constraints on evolution can be studied experimentally by applying hormones systemically and measuring interdependent responses of beneficial and detrimental traits to selection (phenotypic engineering with hormones). Supposing that alteration of one trait in isolation would enhance fitness, cases in which the net effect of endocrine alteration of multiple traits is to depress fitness provide evidence for constraints. We briefly report results of recent studies employing hormonal manipulations, stressing our own work on the dark-eyed junco (Junco hyemalis: Emberizidae). PMID- 29586931 TI - Role of Consumers in Guideline Development Process. AB - Clinical practice guidelines (CPGs) inform patient care by providing recommendations based on a thorough examination of risks and benefits of medical care or intervention. With the ever-increasing importance placed on shared decision making, and because of the valuable perspective on patient-related topics and patient-centered outcomes, consumers of health care have been incorporated in the American Academy of Otolaryngology-Head and Neck Surgery Foundation CPG development process. Consumers bring a unique perspective and add transparency to the guideline development process. In addition, they are instrumental in formulating patient-friendly recommendations that are easier to understand. Studies that have been done to evaluate the role of consumers in the CPG development process found that consumers had a positive impact. In addition, studies report that consumers felt adequately prepared after appropriate training and education on the process. Further studies are needed to understand how to best engage, train, and educate consumers in future guidelines development. PMID- 29587004 TI - Developing a Phosphospecific IHC Assay as a Predictive Biomarker for Topoisomerase I Inhibitors. AB - Phosphorylation is the most extensively studied posttranslational modification of proteins. There are approximately 500 kinases known in the human genome. The kinase-activated pathways regulate almost every aspect of cell function and a deregulated kinase cascade leads to impaired cellular function. Impaired regulation of several kinase cascades, including the epidermal growth factor receptor (EGFR) pathway, leading to tumor pathogenesis, is well documented. Thus, a phosphospecific test with prognostic or predictive value was expected in oncology. However, no phosphospecific IHC test is used in oncology clinics. Human topoisomerase I (topoI) inhibitors, camptothecin and its analogues (CPT), are used extensively to treat various solid tumors. Depending on tumor type, the response rate is only 13-32%. We have demonstrated that the deregulated kinase cascade is at the core of CPT resistance. DNA-PKcs, a kinase central to the DNA double-strand break (DSB) response pathway, phosphorylates topoI at serine 10 (topoI-pS10), and cells with higher basal levels of topoI-pS10 degrade topoI rapidly and are resistant to this class of drug. The higher basal level of topoI phosphorylation is due to continual activation of DNA-PKcs, and one potential mechanism of this pathway activation is failure of upstream effector phosphatases such as phosphatase and tensin homolog (PTEN). Based on this understanding, we have developed an IHC-based test (P-topoIDx) that can stratify the responder and non-responder patient population. PMID- 29587045 TI - Mean Rank, Equipercentile, and Regression Mapping of World Health Organization Quality of Life Brief (WHOQOL-BREF) to EuroQoL 5 Dimensions 5 Levels (EQ-5D-5L) Utilities. AB - BACKGROUND: Existing methods to link preference-based and profile-based health related quality of life (HRQoL) questionnaires have their limitations. Hence, we developed a new mapping method (the mean rank method, MRM) and applied it to map the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) to the EuroQoL 5 Dimensions 5 Levels (EQ-5D-5L). We then compared the new MRM with current methods; i.e., regression-mapped (OLS method) and equipercentile method (EPM). METHODS: Singapore residents, aged >=21 y, were recruited from the general population and 2 outpatient clinics in acute care hospitals. Performance of the MRM was evaluated using both simulation and split-sample validation ( n = 658 in training and n = 657 in validation samples). Using the training sample, we derived 3 sets of mapped EQ-5D-5L utilities based on MRM, OLS method and EPM. Using simulation and the validation sample, we compared the performance of the mapping methods in terms of distribution parameters, mean utility by strata, association with health covariates, and prediction errors at the individual level, among others. RESULTS: The WHOQOL-BREF Physical Health domain is the only domain significantly associated with EQ-5D-5L utilities. Simulation showed that MRM more accurately reproduced the variance and percentiles of the distribution of the observed utilities than did the OLS method or EPM. OLS method tended to underestimate the mean utility of good health states, overestimate the mean utility of poor health states, and underestimate the association with covariates. An analysis of validation sample gave similar results. CONCLUSION: In scenarios similar to the mapping of WHOQOL-BREF to the EQ-5D-5L, the MRM outperformed the OLS method and EPM in important-though not all-aspects. The simplicity and reproducibility of the MRM makes it an attractive alternative to current methods. PMID- 29587047 TI - Microsimulation Modeling for Health Decision Sciences Using R: A Tutorial. AB - Microsimulation models are becoming increasingly common in the field of decision modeling for health. Because microsimulation models are computationally more demanding than traditional Markov cohort models, the use of computer programming languages in their development has become more common. R is a programming language that has gained recognition within the field of decision modeling. It has the capacity to perform microsimulation models more efficiently than software commonly used for decision modeling, incorporate statistical analyses within decision models, and produce more transparent models and reproducible results. However, no clear guidance for the implementation of microsimulation models in R exists. In this tutorial, we provide a step-by-step guide to build microsimulation models in R and illustrate the use of this guide on a simple, but transferable, hypothetical decision problem. We guide the reader through the necessary steps and provide generic R code that is flexible and can be adapted for other models. We also show how this code can be extended to address more complex model structures and provide an efficient microsimulation approach that relies on vectorization solutions. PMID- 29587086 TI - Longitudinal Tracking of Sound Exposure and Hearing Aid Usage through Objective Data Logs. AB - Objective To use data-logging technology to objectively track and identify predictors of hearing aid (HA) usage and aided sound exposure. Study Design Case series with planned data collection. Setting Tertiary academic medical center. Subjects and Methods Individuals with HAs between 2007 and 2016 were included (N = 431; mean, 74.6 years; 95% CI, 73.1-76.0). Data-logging technology intrinsic to new-generation HAs was enabled to track usage and sound exposure. With multivariable linear regression, age, sex, number of audiology visits, duration of audiologic follow-up, pure tone average, and HA side were assessed as predictors of usage (hours/day) and aided sound exposure (dB-hours/day; ie, "dose" of sound per day). Results Mean follow-up was 319 days (95% CI, 277-360). Mean HA usage was 8.4 hours/day (95% CI, 8.0-8.8; N = 431). Mean aided sound exposure was 440 dB-hours/day (95% CI, 385-493; n = 110). HA use (beta < 0.001, P = .45) and aided sound exposure (beta = -0.006, P = .87) were both stable over time. HA usage was associated only with hearing loss level (pure tone average; beta = 0.030, P = .04). Aided sound exposure was associated only with duration of audiologic follow-up (beta = 0.100, P = .02). Conclusion While measurement of HA use has traditionally relied on subjective reporting, data logging offers an objective tool to longitudinally track HA use and sound exposure. We demonstrate the feasibility of using this potentially powerful research tool. Usage and sound exposure were stable among patients throughout the study period. Use was greater among subjects with greater hearing loss. Maximizing aided sound exposure might be possible through continued audiology follow-up visits. PMID- 29587129 TI - Musical Preferences Predict Personality: Evidence From Active Listening and Facebook Likes. AB - Research over the past decade has shown that various personality traits are communicated through musical preferences. One limitation of that research is external validity, as most studies have assessed individual differences in musical preferences using self-reports of music-genre preferences. Are personality traits communicated through behavioral manifestations of musical preferences? We addressed this question in two large-scale online studies with demographically diverse populations. Study 1 ( N = 22,252) shows that reactions to unfamiliar musical excerpts predicted individual differences in personality most notably, openness and extraversion-above and beyond demographic characteristics. Moreover, these personality traits were differentially associated with particular music-preference dimensions. The results from Study 2 ( N = 21,929) replicated and extended these findings by showing that an active measure of naturally occurring behavior, Facebook Likes for musical artists, also predicted individual differences in personality. In general, our findings establish the robustness and external validity of the links between musical preferences and personality. PMID- 29587128 TI - Direct Analysis of Pathogenic Structures Affixed to the Tympanic Membrane during Chronic Otitis Media. AB - Objective To characterize otitis media-associated structures affixed to the mucosal surface of the tympanic membrane (TM) in vivo and in surgically recovered in vitro samples. Study Design Prospective case series without comparison. Setting Outpatient surgical care center. Subjects and Methods Forty pediatric subjects scheduled for tympanostomy tube placement surgery were imaged intraoperatively under general anesthesia. Postmyringotomy, a portable optical coherence tomography (OCT) imaging system assessed for the presence of any biofilm affixed to the mucosal surface of the TM. Samples of suspected microbial infection-related structures were collected through the myringotomy incision. The sampled site was subsequently reimaged with OCT to confirm collection from the original image site on the TM. In vitro analysis based on confocal laser scanning microscope (CLSM) images of fluorescence in situ hybridization-tagged samples and polymerase chain reaction (PCR) provided microbiological characterization and verification of biofilm activity. Results OCT imaging was achieved for 38 of 40 subjects (95%). Images from 38 of 38 (100%) of subjects observed with OCT showed the presence of additional microbial infection-related structures. Thirty-four samples were collected from these 38 subjects. CLSM images provided evidence of clustered bacteria in 32 of 33 (97%) of samples. PCR detected the presence of active bacterial DNA signatures in 20 of 31 (65%) of samples. Conclusion PCR and CLSM analysis of fluorescence in situ hybridization-stained samples validates the presence of active bacteria that have formed into a middle ear biofilm that extends across the mucosal layer of the TM. OCT can rapidly and noninvasively identify middle ear biofilms in subjects with severe and persistent cases of otitis media. PMID- 29587130 TI - Astaxanthin counteracts the effects of heat shock on the maturation of bovine oocytes. AB - The cellular mechanisms induced by elevated temperature on oocytes are not fully understood. However, there is evidence that some of the deleterious effects of heat shock are mediated by a heat-induced increase in reactive oxygen species (ROS). In this context, carotenoid antioxidants might have a thermoprotective effect. Therefore, the objective of this study was to determine the role of astaxanthin (AST) on oocyte ROS production and on the redox profile and developmental competency of cumulus-oocyte complexes (COCs) after 14h heat shock (41 degrees C) during in vitro maturation (IVM). Exposure of oocytes to heat shock during IVM increased ROS and reduced the ability of the oocyte to cleave and develop to the blastocyst stage. However, 12.5 and 25nM astaxanthin rescued these negative effects of heat shock; astaxanthin counteracted the heat shock induced increase in ROS and restored oocyte developmental competency. There was no effect of astaxanthin on maturation medium lipid peroxidation or on glutathione peroxidase and catalase activity in oocytes and cumulus cells. However, astaxanthin stimulated superoxide dismutase (SOD) activity in heat shocked cumulus cells. In conclusion, direct heat shock reduced oocyte competence, which was restored by astaxanthin, possibly through regulation of ROS and SOD activity in oocytes and COCs. PMID- 29587131 TI - Task switching costs in preschool children and adults. AB - Past research investigating cognitive flexibility has shown that preschool children make many perseverative errors in tasks that require switching between different sets of rules. However, this inflexibility might not necessarily hold with easier tasks. The current study investigated the developmental differences in cognitive flexibility using a task-switching procedure that compared reaction times and accuracy in 4- and 6-year-olds with those in adults. The experiment involved simple target detection tasks and was intentionally designed in a way that the stimulus and response conflicts were minimal together with a long preparation window. Global mixing costs (performance costs when multiple tasks are relevant in a context), and local switch costs (performance costs due to switching to an alternative task) are typically thought to engage endogenous control processes. If this is the case, we should observe developmental differences with both of these costs. Our results show, however, that when the accuracy was good, there were no age differences in cognitive flexibility (i.e., the ability to manage multiple tasks and to switch between tasks) between children and adults. Even though preschool children had slower reaction times and were less accurate, the mixing and switch costs associated with task switching were not reliably larger for preschool children. Preschool children did, however, show more commission errors and greater response repetition effects than adults, which may reflect differences in inhibitory control.

AB - A novel 5,6-diaryl-1,2,4-triazine thiazole derivatives (7a-7q) were synthesized and characterized by 1H NMR and 13C NMR and evaluated for their alpha-glucosidase inhibitory activity. All tested compounds displayed good alpha-glucosidase inhibitory activity with IC50 values ranging between 2.85 +/- 0.13 and 14.19 +/- 0.23 MUM when compared to the standard drug acarbose (IC50 = 817.38 +/- 6.27 MUM). Compound 7i (IC50 = 2.85 +/- 0.13 MUM) exhibited the highest activity among this series of compounds. Molecular docking studies were carried out in order to investigate the binding mode of this class of compounds to alpha-glucosidase. This study showed that these 5,6-diaryl-1,2,4-triazine thiazole derivatives are a new class of alpha-glucosidase inhibitors. PMID- 29587133 TI - The role of Hedgehog signaling in cementoblast differentiation. AB - OBJECTIVE: It has been well known that Hedgehog (Hh) signaling plays an important role in bone development, however, its function in cementogenesis has not yet been reported. This study was intended to elucidate the role of Hh signaling in cementoblast differentiation. DESIGN: Expression changes of various Hh signaling components and levels of skeletogenic markers (alkaline phosphatase, osteocalcin, osteopontin) and osteogenic transcription factors (RUNX2, Osterix) by Hh signaling modulators during OCCM-30 cementoblast differentiation were determined by quantitative real-time reverse transcriptase polymerase chain reaction. To investigate effects of Hh signaling modulators on the mineralization of cementoblast, alkaline phosphatase and alizarin red S staining were used. Then, the interaction between Hh and BMP signaling during cementoblast differentiation was evaluated using co-treatment of BMP7 and Hh signaling modulators. RESULTS: We observed the consistent expression of Hh signaling molecules in the OCCM-30, which were up-regulated during cementoblast differentiation. We also found that the treatment of cells with Purmo, an Hh activator, enhanced cementoblast differentiation by increasing the mRNA expression of skeletogenic markers and osteogenic transcription factors, as well as increasing alkaline phosphate activity and mineralization capability. On the contrary, an Hh antagonist, like Cyclo, effectively inhibited cementoblast differentiation. Furthermore, BMP7 promoted cementoblast differentiation through crosstalk with the Hh signaling. CONCLUSION: These results suggest that Hh signaling is involved in cementoblast differentiation, and Hh signaling molecules may therefore represent new therapeutic targets in periodontal treatment and regeneration. PMID- 29587135 TI - Clinical duration of eruption of deciduous teeth in Jordanian children: A cross sectional study. AB - OBJECTIVE: The aim of this study was to investigate the clinical duration of eruption (CDE) for deciduous teeth in Jordanian children, from the moment of gingival emergence until functional occlusal contact. DESIGN: This cross sectional study included 1988 children (885 females, 1103 males) aged 1-45 months examined for deciduous tooth emergence. Through probit regression analysis (SPSS Version 16.0), the median ages of emergence (MAE) and of functional eruption (MAF) were calculated per tooth; time difference between the two events represented CDE in months. Mann Whitney U tests and two-tailed Spearman's bivariate correlation test were used to investigate sexual dimorphisms in CDE, and find relationships between MAE and CDE, respectively. Significance was set at P <= 0.05. RESULTS: The average CDE was (4.45 +/- 1.96) months; it was less in males (4.33 +/- 1.99) than in females (4.57 +/- 1.93) with no significant gender differences (P = 0.38). Longest and shortest CDE were for maxillary first molars and mandibular lateral incisors, respectively. None of the teeth showed statistically significant differences in CDEs between genders. In addition, there were insignificant positive moderate correlations between MAE and CDE (r = 0.60, 0.52, P = 0.07, 0.12 for males and females, respectively). CONCLUSIONS: This study has established the first standards for CDE in deciduous teeth for Jordanian children with an average CDE (4.5 +/- 2, range 1.6-8 months). Some variations in CDE can be explained by variations in age of emergence however, variations in CDE were not related to gender. The deciduous dentition in Jordanians is in active state of eruption between approximately 8.2-32 months.

AB - OBJECTIVE: This study evaluated the capacity of sodium hexametaphosphate (HMP) at different concentrations to alter the surface properties of dental enamel in order to increase calcium and phosphate adsorption. DESIGN: Bovine enamel blocks (4 mm * 4 mm, n = 144, 12/group) were divided: 0%; 0.25%; 0.5%; and 1% HMP, followed or not by application of solutions containing Ca or Ca-PO4, totaling 12 groups. The treatments were performed for 2 min, and the surface free energy (mN/m) was calculated by measuring the contact angles of three probing liquids (deionized water, diiodomethane and ethylene glycol), which was used to determine the polar and nonpolar components of the enamel surface. Calcium (Ca), phosphate (PO4) and HMP in the solutions treatment solutions were analyzed before and after treatment. The data presented normal and homogeneous distribution and then were subjected to ANOVA, followed by Student-Newman Keuls' test (p < 0.05). RESULTS: The higher the% of HMP in the solutions, the greater HMP adsorption and more electron-donor sites on enamel surface were achieved (p < 0.05). Also, Ca adsorption was higher with increasing% HMP in the solutions (p < 0.05), which in turn reduced electron-donor sites on enamel surface. Increased Ca and PO4 adsorption occurred at 0.5% and 1% HMP after treatment with Ca-PO4 solution, resulting in a less electron-donor sites on surface when compared to the other treatments (P < 0.05). CONCLUSIONS: HMP leads to a more electron-donor sites on enamel surface, what promotes greater adsorption of Ca and PO4 ions.

AB - The production and crystallinity of 13C bacterial cellulose (BC) was examined in static culture of Komagataeibacter xylinus with different chemical and physical stimuli: the addition of NaCl or cloramphenicol as well as exposure to a magnetic field or to UV light. Crystalline BC biosynthesized under each stimulus was studied by XRD and solid state 13C NMR analyses. All treatments produced BC with enhanced crystallinity over 90% (XRD) and 80% (NMR) compared to the control (83 and 76%, respectively) or to Avicel (77 and 62%, respectively). The XRD data indicated that the crystallite size was 80-85 A. Furthermore, changes on the allomorphs (Ialpha and Ibeta) ratio tendency of BC samples addressed to the stimuli were estimated using the C4 signal from 13C NMR data. These results showed a decrease of the allomorph Ialpha (3%) when BC was biosynthesized with UV light and chloramphenicol compared to control (58.79%). In contrast, the BC obtained with NaCl increased up to 60.31% of the Ialpha allomorph ratio.

In this study we synthesized two series of 4,6-O-benzylidene acetal protected beta-1,2,3-triazolyl glycoside of D-glucose and N-acetyl D-glucosamine derivatives and evaluated their self-assembling properties in a few solvents. Several gelators were obtained and the gelation properties of these compounds rely on the structures of the 4 triazolyl substituents. Typically, alkyl derivatives resulted in effective gelation in organic solvents and aqueous mixtures of ethanol and dimethyl sulfoxide. But further acetylation of these compounds resulted in loss of gelation properties. The gels were characterized using optical microscopy, rheology, and FTIR spectroscopy. We also analyzed the molecular assemblies, using 1H NMR spectroscopy to probe the influences of the hydroxyl, amide, and triazole functional groups. Naproxen was used as a model drug and it formed co-gels with compound 25 in DMSO water mixtures. Using UV spectroscopy, we found that naproxen was slowly released from the gel to aqueous solution. The general structure and gelation trend obtained here can be useful in designing sugar based biomaterials. We expect that further structural optimization can lead to more effective gelators that are compatible with different drug molecules for encapsulation and sustained release.

In this issue of Developmental Cell, Yang et. al. (2018) find that basal cells emerge very early in lung development and that a subset of these contributes to the expansive epithelial wound response observed after influenza injury. PMID- 29587139 TI - Quality before Quantity: Inspecting CFTR. AB - CFTR biosynthesis is highly dynamic. In this issue of Developmental Cell, Okiyoneda et al. (2018) show that RFFL serves as a CFTR conformation scrutinizer at the plasma membrane. It recognizes misfolded CFTR proteins and marks them for degradation. This quality control mechanism may be explored to benefit cystic fibrosis patients. PMID- 29587140 TI - piRNA Rules of Engagement. AB - piRNAs are known to silence transposable elements, but not all piRNAs match transposon sequences. Recent studies from Shen et al. (2018) and Zhang et al. (2018) identify rules for piRNA target recognition in Caenorhabditis elegans. Permissive pairing rules allow targeting of essentially all germline mRNAs, while protective mechanisms prevent silencing self-genes. PMID- 29587141 TI - Exploring the Function of Dynamic Phosphorylation-Dephosphorylation Cycles. AB - Protein phosphorylation is a dynamic post-translational modification critical for biological responses. At the level of individual molecules, phosphorylation dynamics can have important functional implications, but this information is rarely quantified. We discuss how rapid phosphorylation-dephosphorylation cycles could underlie important signaling properties, including the ability to rapidly bind and release proteins. PMID- 29587142 TI - Developmental History Provides a Roadmap for the Emergence of Tumor Plasticity. AB - We show that the loss or gain of transcription factor programs that govern embryonic cell-fate specification is associated with a form of tumor plasticity characterized by the acquisition of alternative cell fates normally characteristic of adjacent organs. In human non-small cell lung cancers, downregulation of the lung lineage-specifying TF NKX2-1 is associated with tumors bearing features of various gut tissues. Loss of Nkx2-1 from murine alveolar, but not airway, epithelium results in conversion of lung cells to gastric-like cells. Superimposing oncogenic Kras activation enables further plasticity in both alveolar and airway epithelium, producing tumors that adopt midgut and hindgut fates. Conversely, coupling Nkx2-1 loss with foregut lineage-specifying SOX2 overexpression drives the formation of squamous cancers with features of esophageal differentiation. These findings demonstrate that elements of pathologic tumor plasticity mirror the normal developmental history of organs in that cancer cells acquire cell fates associated with developmentally related neighboring organs.

AB - Phosphatidylinositol (PtdIns) transfer proteins (PITPs) stimulate PtdIns-4-P synthesis and signaling in eukaryotic cells, but to what biological outcomes such signaling circuits are coupled remains unclear. Herein, we show that two highly related StART-like PITPs, PITPNA and PITPNB, act in a redundant fashion to support development of the embryonic mammalian neocortex. PITPNA/PITPNB do so by driving PtdIns-4-P-dependent recruitment of GOLPH3, and likely ceramide transfer protein (CERT), to Golgi membranes with GOLPH3 recruitment serving to promote MYO18A- and F-actin-directed loading of the Golgi network to apical processes of neural stem cells (NSCs). We propose the primary role for PITP/PtdIns-4 P/GOLPH3/CERT signaling in NSC Golgi is not in regulating bulk membrane trafficking but in optimizing apically directed membrane trafficking and/or apical membrane signaling during neurogenesis. PMID- 29587144 TI - Nutritional Control of Stem Cell Division through S-Adenosylmethionine in Drosophila Intestine. AB - The intestine has direct contact with nutritional information. The mechanisms by which particular dietary molecules affect intestinal homeostasis are not fully understood. In this study, we identified S-adenosylmethionine (SAM), a universal methyl donor synthesized from dietary methionine, as a critical molecule that regulates stem cell division in Drosophila midgut. Depletion of either dietary methionine or SAM synthesis reduces division rate of intestinal stem cells. Genetic screening for putative SAM-dependent methyltransferases has identified protein synthesis as a regulator of the stem cells, partially through a unique diphthamide modification on eukaryotic elongation factor 2. In contrast, SAM in nutrient-absorptive enterocytes controls the interleukin-6-like protein Unpaired 3, which is required for rapid division of the stem cells after refeeding. Our study sheds light upon a link between diet and intestinal homeostasis and highlights the key metabolite SAM as a mediator of cell-type-specific starvation response. PMID- 29587146 TI - Pullout strength of standard vs. cement-augmented rotator cuff repair anchors in cadaveric bone. AB - BACKGROUND: We evaluate a novel method of rotator cuff repair that uses arthroscopic equipment to inject bone cement into placed suture anchors. A cadaver model was used to assess the pullout strength of this technique versus anchors without augmentation. METHODS: Six fresh-frozen matched pairs of upper extremities were screened to exclude those with prior operative procedures, fractures, or neoplasms. One side from each pair was randomized to undergo standard anchor fixation with the contralateral side to undergo anchor fixation augmented with bone cement. After anchor fixation, specimens were mounted on a servohydraulic testing system and suture anchors were pulled at 90 degrees to the insertion to simulate the anatomic pull of the rotator cuff. Sutures were pulled at 1 mm/s until failure. FINDINGS: The mean pullout strength was 540 N (95% confidence interval, 389 to 690 N) for augmented anchors and 202 N (95% confidence interval, 100 to 305 N) for standard anchors. The difference in pullout strength was statistically significant (P < 0.05). INTERPRETATION: This study shows superior pullout strength of a novel augmented rotator cuff anchor technique. The described technique, which is achieved by extruding polymethylmethacrylate cement through a cannulated in situ suture anchor with fenestrations, significantly increased the ultimate failure load in cadaveric human humeri. This novel augmented fixation technique was simple and can be implemented with existing instrumentation. In osteoporotic bone, it may substantially reduce the rate of anchor failure. PMID- 29587145 TI - Spatial-Temporal Lineage Restrictions of Embryonic p63+ Progenitors Establish Distinct Stem Cell Pools in Adult Airways. AB - Basal cells (BCs) are p63-expressing multipotent progenitors of skin, tracheoesophageal and urinary tracts. p63 is abundant in developing airways; however, it remains largely unclear how embryonic p63+ cells contribute to the developing and postnatal respiratory tract epithelium, and ultimately how they relate to adult BCs. Using lineage-tracing and functional approaches in vivo, we show that p63+ cells arising from the lung primordium are initially multipotent progenitors of airway and alveolar lineages but later become restricted proximally to generate the tracheal adult stem cell pool. In intrapulmonary airways, these cells are maintained immature to adulthood in bronchi, establishing a rare p63+Krt5- progenitor cell population that responds to H1N1 virus-induced severe injury. Intriguingly, this pool includes a CC10 lineage labeled p63+Krt5- cell subpopulation required for a full H1N1-response. These data elucidate key aspects in the establishment of regionally distinct adult stem cell pools in the respiratory system, potentially with relevance to other organs. PMID- 29587147 TI - Load transfer and periprosthetic fractures after total hip arthoplasty: Comparison of periprosthetic fractures of femora implanted with cementless distal load or proximal-load femoral components and measurement of the femoral strain at the time of implantation. AB - BACKGROUND: Little is known about the causes and mechanisms underlying periprosthetic fractures around femoral components particularly in relation to the stem design. In an in vitro study 20 pairs of fresh cadaveric femora were loaded to fracture axially and transversally. FINDINGS: When proximal femoral strain was measured at the time of impaction of cementless stems the load transfer was determined by the underlying anatomy rather than by the shape of the stem, so that the so-called "load transfer" properties - proximal or distal - ascribed to stem designs are a myth. The axial-load and the transverse-load model were then exposed to loads to failure (fracture) and showed a biphasic pattern throughout independent of the impact direction. In the second phase, the fracture phase proper, the bone behaved like a brittle solid. Failure occurred very rapidly within less than 5 milliseconds. The forces to failure were between 2 and 11 kN. Most of the fractures (82.5%) occurred above the stem tip. INTERPRETATION: Note that the study was confined to early preosteointegration fractures. Neither the stem design nor the impact direction, i.e. on the knee or on the side of the hip, was related to the fracture morphology. PMID- 29587148 TI - Posterior or anterolateral approach in hip joint arthroplasty - Impact on frontal plane moment. AB - BACKGROUND: Anterolateral surgical approach in hip joint arthroplasty necessitates division of the hip abductor muscle complex, which may compromise postoperative gait observed in the frontal plane. The aim of the study was to compare frontal plane moment after hip joint arthroplasty by anterolateral or posterior approach and to explore which compensatory strategies patients use to decrease frontal plane moment. METHODS: Twenty-eight patients were randomized by sealed envelopes to hip resurfacing arthroplasty surgery by anterolateral (ad modum Watson) or posterior (ad modum Moore) approach, performed by two senior surgeons. Gait analyses were performed using 3D motion capture before surgery, 3, and 12 months after surgery. Peak ground reaction force was extracted for early and late stance and the corresponding frontal plane moment was defined. Measures of lateral trunk inclination, pelvic drop and hip abduction were obtained for the stance phase of the affected leg. FINDINGS: An effect of surgical approach on frontal plane moment for the affected leg was found during early stance phase (p = 0.006) where average frontal plane moment in the anterolateral groups was 202.42 N mm/kg in less compared to the posterior group after one year. A similar effect from baseline to 12 months for trunk inclination (p = 0.03) and an overall negative correlation between frontal plane moment and trunk inclination was found (r = -0.66, p = 0.03). INTERPRETATION: Frontal plane moment during early stance was less one year after hip joint arthroplasty through anterolateral compared to posterior approach. Patients' primary strategy to reduce frontal plane moment seems to be increased lateral trunk inclination. PMID- 29587150 TI - Micro finite element analysis of dental implants under different loading conditions. AB - Osseointegration is paramount for the longevity of dental implants and is significantly influenced by biomechanical stimuli. The aim of the present study was to assess the micro-strain and displacement induced by loaded dental implants at different stages of osseointegration using finite element analysis (FEA). Computational models of two mandible segments with different trabecular densities were constructed using microCT data. Three different implant loading directions and two osseointegration stages were considered in the stress-strain analysis of the bone-implant assembly. The bony segments were analyzed using two approaches. The first approach was based on Mechanostat strain intervals and the second approach was based on tensile/compression yield strains. The results of this study revealed that bone surrounding dental implants is critically strained in cases when only a partial osseointegration is present and when an implant is loaded by buccolingual forces. In such cases, implants also encounter high stresses. Displacements of partially-osseointegrated implant are significantly larger than those of fully-osseointegrated implants. It can be concluded that the partial osseointegration is a potential risk in terms of implant longevity. PMID- 29587149 TI - Neurophysiological and cognitive effects of Transcranial Direct Current Stimulation in three girls with Rett Syndrome with chronic language impairments. AB - BACKGROUND: this study was based on both neurophysiological decelerated activity and communication deficits in Rett Syndrome (RTT). AIMS: the aim was to examine the neurophysiological and cognitive effects of Transcranial Direct Current Stimulation (tDCS) in three girls with RTT with chronic language impairments. METHODS AND PROCEDURES: we proposed an integrated intervention: tDCS and cognitive empowerment applied to language in order to enhance speech production (new functional sounds and new words). Because maximal gains usually are achieved when tDCS is coupled with behavioral training, we applied tDCS stimulation on Broca's area together with linguistic training. OUTCOMES AND RESULTS: the results indicated a general enhancement in language abilities (an increase in the number of vowel/consonant sounds and words and the production and comprehension through discrimination), motor coordination (functional movements), and neurophysiological parameters (an increase in the frequency and power of alpha, beta and theta bands). CONCLUSION AND IMPLICATIONS: we assume that tDCS stimulation combined with the cognitive empowerment applied to language can significantly influence a chronic impairment even in genetic syndromes. Our results provide data that support the role of tDCS in fostering brain plasticity and in particular in empowering speech production and comprehension in girls with RTT. PMID- 29587151 TI - Effect of preconditioning on silver leaching and bromide removal properties of silver-impregnated activated carbon (SIAC). AB - Silver impregnated activated carbon (SIAC) has been found to be effective in mitigating the formation of brominated-disinfection by products during drinking water treatment. However, there are still uncertainties regarding its silver leaching properties, and strategies for the prevention of silver leaching have remained elusive. This study focused on the evaluation of one type of commercially available SIAC for its ability to remove bromide while minimising silver leaching from the material. Both synthetic and real water matrices were tested. Depending on solution pH, it was found that changing the surface charge properties of SIAC, as measured by the point of zero charge pH, can result in additional bromide removal while minimising the extent of silver leaching. To better understand the mechanism of silver leaching from the SIAC, eight preconditioning environments, i.e. variable pH and ionic strength were tested for a fixed amount of SIAC and two preconditioning environments were selected for a more detailed investigation. Experiments carried out in synthetic water showed that preconditioning at pH 10.4 did not deteriorate the capacity of SIAC to remove bromide, but significantly decreased the release of silver in the form of ionic silver (Ag+), silver bromide (AgBr) and silver chloride (AgCl) from 40% for the pristine to 3% for the treated SIAC. This was confirmed using a groundwater sample. These results suggest that preconditioned SIAC has the potential to be an effective method for bromide removal with minimised silver leaching in a long term field application for drinking water production. PMID- 29587152 TI - Identifying, counting, and characterizing superfine activated-carbon particles remaining after coagulation, sedimentation, and sand filtration. AB - Superfine powdered activated carbon (SPAC; particle diameter ~1 MUm) has greater adsorptivity for organic molecules than conventionally sized powdered activated carbon (PAC). Although SPAC is currently used in the pretreatment to membrane filtration at drinking water purification plants, it is not used in conventional water treatment consisting of coagulation-flocculation, sedimentation, and rapid sand filtration (CSF), because it is unclear whether CSF can adequately remove SPAC from the water. In this study, we therefore investigated the residual SPAC particles in water after CSF treatment. First, we developed a method to detect and quantify trace concentration of carbon particles in the sand filtrate. This method consisted of 1) sampling particles with a membrane filter and then 2) using image analysis software to manipulate a photomicrograph of the filter so that black spots with a diameter >0.2 MUm (considered to be carbon particles) could be visualized. Use of this method revealed that CSF removed a very high percentage of SPAC: approximately 5-log in terms of particle number concentrations and approximately 6-log in terms of particle volume concentrations. When waters containing 7.5-mg/L SPAC and 30-mg/L PAC, concentrations that achieved the same adsorption performance, were treated, the removal rate of SPAC was somewhat superior to that of PAC, and the residual particle number concentrations for SPAC and PAC were at the same low level (100 200 particles/mL). Together, these results suggest that SPAC can be used in place of PAC in CSF treatment without compromising the quality of the filtered water in terms of particulate matter contamination. However, it should be noted that the activated carbon particles after sand filtration were smaller in terms of particle size and were charge-neutralized to a lesser extent than the activated carbon particles before sand filtration. Therefore, the tendency of small particles to escape in the filtrate would appear to be related to the fact that their small size leads to a low destabilization rate during the coagulation process and a low collision rate during the flocculation and filtration processes. PMID- 29587153 TI - Two-dimensional 1H and 1H-detected NMR study of a heterogeneous biocatalyst using fast MAS at high magnetic fields. AB - Nuclear magnetic resonance (NMR) is a powerful tool for investigating atomic scale structure in heterogeneous or composite materials where long-range order is absent. In this work solid-state 1H and 1H-detected NMR experiments were performed with fast magic angle spinning (nuR = 75 kHz) and at high magnetic fields (B0 = 20 T) and used to gain structural insight into a heterogeneous biocatalyst consisting of an enzyme, human carbonic anhydrase II (hCA II), covalently immobilized on epoxy-functionalized silica. Two-dimensional 1H-1H NOESY-type correlation experiments were able to provide information on 1H environments in silica, epoxy-silica and the immobilized enzyme. Two distinct signals originating from water protons were observed: water associated with the surface of the silica and the water associated with the immobilized enzyme. Additional two-dimensional 1H-1H double-single quantum (DQ-SQ) correlation experiments suggested that the immobilized enzyme is not in close contact with the silica surface. Most significantly, comparison of two-dimensional 1H-15N spectra of the immobilized enzyme and the solution-state enzyme confirmed that the structural integrity of the protein is well preserved upon covalent immobilization. PMID- 29587154 TI - Intracellular osteopontin negatively regulates toll-like receptor 4-mediated inflammatory response via regulating GSK3beta and 4EBP1 phosphorylation. AB - Toll-like receptors (TLRs) play an important role in host defense against invading pathogens. By initiating a signal transduction cascade, TLRs lead to the release of pro-inflammatory cytokines. However, the inappropriate activation of TLR signaling could result in inflammatory disorders or autoimmune diseases. Osteopontin (OPN) has been reported to be an inflammatory cytokine participating in cell-mediated immunity. However, the role of OPN in TLR-mediated immune responses is poorly understood. In the present study, OPN-deficient (OPN-/-) macrophages exhibited significantly higher levels of pro-inflammatory cytokines after stimulation with lipopolysaccharide (LPS). Our study also demonstrated that the intracellular OPN (iOPN) isoform acted as a negative regulator to inhibit LPS induced inflammatory responses. Compared to WT macrophages, OPN-/- macrophages had lower Akt phosphorylation levels and higher GSK3beta phosphorylation levels, which were downregulated by p-Akt. Moreover, as a down-stream target of Akt, 4EBP1 was hypo-phosphorylated in OPN-/- macrophages compared to 4EBP1 in WT macrophages. These findings reveal that iOPN can regulate GSK3beta and 4EBP1 phosphorylation to inhibit TLR4-mediated inflammatory responses. PMID- 29587155 TI - CXCL8 hyper-signaling in the aortic abdominal aneurysm. AB - There are indications for elevated CXCL8 levels in abdominal aortic aneurysm disease (AAA). CXCL8 is concurrently involved in neutrophil-mediated inflammation and angiogenesis, two prominent and distinctive characteristics of AAA. As such we considered an evaluation of a role for CXCL8 in AAA progression relevant. ELISA's, real time PCR and array analysis were used to explore CXCL8 signaling in AAA wall samples. A role for CXCL8 in AAA disease was tested through the oral CXCR1/2 antagonist DF2156A in the elastase model of AAA disease. There is an extreme disparity in aortic wall CXCL8 content between AAA and aortic atherosclerotic disease (median [IQR] aortic wall CXCL8 content: 425 [141-1261] (AAA) vs. 23 [2.8-89] (atherosclerotic aorta) ug/g protein (P < 1 . 10-14)), and abundant expression of the CXCR1 and 2 receptors in AAA. Array analysis followed by pathway analysis showed that CXCL8 hyper-expression in AAA is followed increased by IL-8 signaling (Z-score for AAA vs. atherosclerotic control: 2.97, p < 0.0001). Interference with CXCL8 signaling through DF2156A fully abrogated AAA formation and prevented matrix degradation in the murine elastase model of AAA disease (p < 0.001). CXCL8-signaling is a prominent and distinctive feature of AAA, interference with the pathway constitutes a promising target for medical stabilization of AAA. PMID- 29587156 TI - Morphometric analysis of posterior fossa and craniovertebral junction in subtypes of Chiari malformation. AB - OBJECTIVES: Chiari malformations (CMs) are a group of disorders defined by anatomic anomalies of the cerebellum, brainstem, and craniovertebral junction (CVJ). In this study, we aimed to investigate morphometry of posterior fossa and CVJ in subtypes of CM and in control group, and to bring up a matter a correlation with demographic data and subtypes of CM. PATIENTS AND METHODS: The study group included patients managed for CM between 2012 and 2016 and control group. Radiological evaluation was studied by special programs and formulas. Intracranial volumes and morphometric datas of posterior fossa and CVJ were recorded retrospectively. RESULTS: Of the 141 patients, 91 had CM and 50 were control group participants. Mean age was 34.75. Patients were classified as CM-0 (n:10), CM-1 (n:45), CM-1.5 (n:21), CM-2 (n:15). There were statistically significance between Chiari subtypes by syringomyelia (SM) presence (p ? 0.01), SM localization (p ? 0.01), posterior fossa volume (PFV) (p ? 0.01), length of clivus (LoC) and length of subocciput (LoSO) (p ? 0.01 for both), angle between clivus and subocciput (C-SO angle) (p ? 0.01), and clivo-dental angle (C-D angle) (p ? 0.01). CONCLUSION: On morphometric comparison of CM subtypes we concluded that etiological differences lead to morphological differences. CM-2 has remarkable differences from both other subtypes and the control group. PMID- 29587157 TI - Cancer mortality rates and spillover effects among different areas: A case study in Campania (southern Italy). AB - The present study analyses the spatial distribution of cancer mortality rates in Campania (an Italian region with the highest population density), in which residents in several areas are exposed to major environmental health hazards. The paper has the methodological aims of verifying the existence, or otherwise, of a spatial correlation between mortality from different types of cancer and the occurrence of some specific area characteristics, using both Bayesian statistics and spatial econometrics. We show that the use of the Spatial Empirical Bayes Smoothed Rate, instead of the more commonly used Raw Rate, allows a more comprehensive analysis of the mortality rate, highlighting the existence of different cluster sizes throughout the region, according to the type of cancer mortality rate analysed. By using a Spatial Durbin model we verify that cancer mortality rates are related to the environmental characteristics of specific areas with spatial spillover effects. Our results validate the hypothesis that living along the coast by Mt Vesuvius and, to a lesser extent, along the Domitio Flegreo coast NW of Naples and in more urbanised municipalities, increases the risk of dying of cancer. By contrast, living in less urbanised municipalities, with the presence of natural and historical attractions, has a positive effect on the residents' health, reducing their risk of disease. In both cases significant spillover effects (negative and positive) are found in municipalities close to the areas in question. Despite a number of reasonable limitations, our findings may provide useful information support for policy makers to foster knowledge, awareness and informed participation of citizens. PMID- 29587158 TI - Low-Frequency rTMS as an alternative for suicidality and depression, in a patient with multiple medical comorbidities precluding ECT. PMID- 29587159 TI - A cluster randomized controlled platform trial comparing group MEmory specificity training (MEST) to group psychoeducation and supportive counselling (PSC) in the treatment of recurrent depression. AB - Impaired ability to recall specific autobiographical memories is characteristic of depression, which when reversed, may have therapeutic benefits. This cluster randomized controlled pilot trial investigated efficacy and aspects of acceptability, and feasibility of MEmory Specificity Training (MEST) relative to Psychoeducation and Supportive Counselling (PSC) for Major Depressive Disorder (N = 62). A key aim of this study was to determine a range of effect size estimates to inform a later phase trial. Assessments were completed at baseline, post treatment and 3-month follow-up. The cognitive process outcome was memory specificity. The primary clinical outcome was symptoms on the Beck Depression Inventory-II at 3-month follow-up. The MEST group demonstrated greater improvement in memory specificity relative to PSC at post-intervention (d = 0.88) and follow-up (d = 0.74), relative to PSC. Both groups experienced a reduction in depressive symptoms at 3-month follow-up (d = 0.67). However, there was no support for a greater improvement in depressive symptoms at 3 months following MEST relative to PSC (d = -0.04). Although MEST generated changes on memory specificity and improved depressive symptoms, results provide no indication that MEST is superior to PSC in the resolution of self-reported depressive symptoms. Implications for later-phase definitive trials of MEST are discussed. PMID- 29587160 TI - Extending neutron autoradiography technique for boron concentration measurements in hard tissues. AB - The neutron autoradiography technique using polycarbonate nuclear track detectors (NTD) has been extended to quantify the boron concentration in hard tissues, an application of special interest in Boron Neutron Capture Therapy (BNCT). Chemical and mechanical processing methods to prepare thin tissue sections as required by this technique have been explored. Four different decalcification methods governed by slow and fast kinetics were tested in boron-loaded bones. Due to the significant loss of the boron content, this technique was discarded. On the contrary, mechanical manipulation to obtain bone powder and tissue sections of tens of microns thick proved reproducible and suitable, ensuring a proper conservation of the boron content in the samples. A calibration curve that relates the 10B concentration of a bone sample and the track density in a Lexan NTD is presented. Bone powder embedded in boric acid solution with known boron concentrations between 0 and 100 ppm was used as a standard material. The samples, contained in slim Lexan cases, were exposed to a neutron fluence of 1012 cm-2 at the thermal column central facility of the RA-3 reactor (Argentina). The revealed tracks in the NTD were counted with an image processing software. The effect of track overlapping was studied and corresponding corrections were implemented in the presented calibration curve. Stochastic simulations of the track densities produced by the products of the 10B thermal neutron capture reaction for different boron concentrations in bone were performed and compared with the experimental results. The remarkable agreement between the two curves suggested the suitability of the obtained experimental calibration curve. This neutron autoradiography technique was finally applied to determine the boron concentration in pulverized and compact bone samples coming from a sheep experimental model. The obtained results for both type of samples agreed with boron measurements carried out by ICP-OES within experimental uncertainties. The fact that the histological structure of bone sections remains preserved allows for future boron microdistribution analysis. PMID- 29587161 TI - A hybrid method on sourceless sensitivity calculation for airborne gamma-ray spectrometer. AB - The sensitivity calculation of airborne gamma-ray spectrometer (AGS) is usually performed by on-ground or in-flight calibration. However, both methods are cost ineffective or not permissive, especially for artificial radioisotopes with short half-lives. Alternative to these methods is the Monte Carlo simulation, which has been widely applied over the last few decades. The greatest challenge to the practicability of the Monte Carlo simulation in the AGS calibration is its low computational efficiency for ensuring an acceptable reliability. This article proposes a hybrid numerical method for the sourceless AGS calibration by combining the deterministic point-kernel approach and the Monte Carlo simulation. This method is not only more efficient than the source-based calibration by an empirical method, but also independent of the source availability for on-ground or in-flight calibration. For a given soil test model, AGS sensitivities calculated by this hybrid method agree well with those obtained from the empirical method for the in-flight calibration. PMID- 29587162 TI - QA measurement of gamma-ray dose and neutron activation using TLD-400 for BNCT beam. AB - TLD-400 (CaF2:Mn) chips were applied for the gamma-ray dose measurement in a PMMA phantom exposed to a BNCT beam because of their very low neutron sensitivity. Since TLD-400 chips possess an adequate amount of Mn activator they have been employed in this work simultaneously for neuron activation measurement. The self irradiation TL signals owing to the decay of the neutron induced 56Mn activity have been applied for a calibration of the TLD-400 chip in situ, where the activities were measured by an HPGe detector system and the energy deposition per disintegration of 56Mn was calculated by applying a Monte Carlo code. It was accidentally found that the irradiated TLD-400 chips were capable of emitting prominent scintillation lights owing to the induced 56Mn activity, which can easily be recorded by the TLD reader without heating and after a calibration can be used to determine the 56Mn activity.

AB - In this work, the analytical capability of the total reflection X-ray fluorescence technique with the S2 PICOFOX spectrometer was investigated. A set of certified reference materials was prepared as solid particulate for TXRF analysis. Experimental data of sensitivity, limits of detection and recovery for many elements were obtained. Good sensitivity and limits of detection with a good recovery range of around 90-110% were achieved. Thus, the TXRF technique exhibits a good analytical potential for its applicability on different materials. PMID- 29587164 TI - Nitric oxide donors for peripheral artery disease. AB - Current management of peripheral arterial disease involves risk factor modification and revascularisation, but many patients are still left with debilitating symptoms. Therefore, new treatment strategies are needed. The importance of nitric oxide, and its role in regulating endothelial function, is well-established. Altering the nitric oxide pathway has been extensively studied as a means of treating vascular disease, including peripheral arterial disease. Statins and ACE inhibitors have been shown to enhance endogenous nitric oxide and improve intermittent claudication symptoms. Studies using l-arginine have produced differing results, for reasons for yet fully understood. A greater understanding of the nitric oxide pathway, and its enzymatic control, has generated more potential therapeutic targets to alter NO levels. PMID- 29587165 TI - Disrupted functional connectivity patterns of the insula subregions in drug-free major depressive disorder. AB - BACKGROUND: Major depressive disorder (MDD) is characterized by impairments in emotional and cognitive functions. Emerging studies have shown that cognition and emotion interact by reaching identical brain regions, and the insula is one such region with functional and structural heterogeneity. Although previous literatures have shown the role of insula in MDD,it remains unclear whether the insular subregions show differential change patterns in MDD. METHODS: Using the resting-state fMRI data in a group of 23 drug-free MDD patients and 34 healthy controls (HCs), we investigated whether the abnormal connectivity patterns of insular sub-regions or any behavioural correlates can be detected in MDD. Further hierarchical cluster analysis was used to identify the functional connectivity clustering patterns of insular sub-regions. RESULTS: Compared with HCs, the MDD exhibited higher connectivities between dorsal agranular insula and inferior parietal lobule and between ventral dysgranular and granular insula and thalamus/habehula, and lower connectivity of hypergranular insula to subgenual anterior cingulate cortex. Moreover, the three subregions with significant group differences were in three separate functional systems along anterior-to-posteior gradient. The anterior and middle insula showed positive correlation with depressive severity, while the posterior insular was to the contrary. LIMITATIONS: The small and unbalanced sample size, only included moderate and severe depression and the possible inter-individual differences may limit the interpretability. CONCLUSIONS: These findings provided evidences for the MDD related effects in functional connectivity patterns of insular subregions, and revealed that the subregions might be involved in different neural circuits associated with the contrary impacts on the depressive symptoms. PMID- 29587166 TI - Difference in proinflammatory cytokines produced by monocytes between patients with major depressive disorder and healthy controls. AB - BACKGROUND: Immune activation and suppression in patients with major depressive disorders (MDD) have been both reported in different studies. We assume that these findings may indicate innate immunological tolerance in MDD, with subclinical elevated level of proinflammatory cytokines and the decrease in innate immune response while encountering pathogens. METHODS: Peripheral monocytes of 50 untreated patients with MDD and 40 healthy controls were isolated and cultured, with or without 10 ng/ml lipopolysacchride (LPS) for 6 h (6 h, LPS+/-), and with LPS for 18 h (18, LPS+). The cell culture supernatants were collected to measure concentrations of tumor necrosis factor-alpha (TNF-alpha), interleukin 6 (IL-6), and interleukin 1 beta (IL-1beta). RESULTS: The baseline concentrations of IL-6 and IL-1beta (6 h, LPS-) were significantly higher in the MDD group than those in the control group. There was no significant difference of TNF-alpha between the two groups. The fold changes of LPS-induced secretion of IL 6 and TNF-alpha from monocytes cultured for 6 and 18 h were all lower in the patient groups, and that was true for IL-1beta as monocytes cultured for 18 h. LIMITATIONS: Given the gap between the results of in vitro experiments and the actual response that happens in vivo when the immune system encounters pathogens from the external world, future research should include in vivo methods to test the results of the current study. CONCLUSIONS: Patients with MDD may have subclinical inflammation during a depressive episode, and the reduced response to LPS in monocytes indicates innate immunological tolerance.

In addition to external mutagens, DNA is continuously damaged by the aqueous environment, cellular metabolites and is prone to strand breakage during replication. Cell duplication is orchestrated by the cell division cycle and specific DNA structures are processed differently depending on where in the cell cycle they are detected. This is often because a specific structure is physiological in one context, for example during DNA replication, while indicating a potentially pathological event in another, such as interphase or mitosis. Thus, contextualising the biochemical entity with respect to cell cycle progression provides information necessary to appropriately regulate DNA processing activities. We review the links between DNA repair and cell cycle context, drawing together recent advances. PMID- 29587167 TI - Effects of silicon nanoparticles on molecular, chemical, structural and ultrastructural characteristics of oat (Avena sativa L.). AB - Nowadays, nanoparticles are extensively being utilized in medicine, industry, and agriculture thus distributed into the environment. Hence, it is essential to examine exactly the impact of these materials on a variety of organisms, including various species of plants. Therefore, in the current study, we compared the effects of sodium silicate and nano silicon (SiNP) (both at two concentrations of 5 and 10 mM) separately on lignification of the xylem cell wall, antioxidant enzyme activities, ultrastructure of leaf and root cells, expression of silicon transporter (Lsi1) and phenylalanine ammonia lyase (PAL), and also evaluated the protein content and chemical content of oat plants (Avena sativa L.) cultured hydroponically. The results indicated that SiNPs didn't have a toxic effect on the oat plants, and in many cases they enhanced plant growth. The effect of SiNPs on the chemical content of the treated plants was almost identical with silicate. The silicon transporter (Lsi1) gene was expressed in plants exposed to SiNPs, however, at lower levels (~37% in roots) than those exposed to silicate treatments. The SiNPs increased PAL expression and lignification in leaves and roots, however, at lower levels those of silicate (?50% in fourth leaves of 10 mM concentration). They were aggregated in the roots (268-366 nm) and deposited in nano size on the cell walls of leaves. In general, their effects in the plants were identical to silicate but differed in intensity. PMID- 29587169 TI - Attachment within life history theory: an evolutionary perspective on individual differences in attachment. AB - In this article, we discuss theory and research on how individual differences in adult attachment mediate the adaptive calibration of reproductive strategies, cognitive schemas, and emotional expression and regulation. We first present an integration of attachment theory and life history theory. Then, we discuss how early harsh and/or unpredictable environments may promote insecure attachment by hampering parents' ability to provide sensitive and reliable care to their children. Finally, we discuss how, in the context of harsh and/or unpredictable environments, different types of insecure attachment (i.e. anxiety and avoidance) may promote evolutionary adaptive reproductive strategies, cognitive schemas, and emotional expression and regulation profiles. PMID- 29587170 TI - The continuous vs discontinuous use of restorative safety behaviors on symptoms of contamination fear: An experimental investigation. AB - BACKGROUND AND OBJECTIVES: Cognitive-behavioral theorists posit that safety behaviors (SBs) interfere with important exposure processes and should be removed from therapy. However, there is growing evidence to suggest that restorative SBs (RSB; those that allow for full confrontation with a core threat) do not adversely affect exposure outcomes, and their implementation during exposure should be further examined. METHODS: The current study evaluated exposure with the continuous use of RSB (E + CONT) versus discontinuation of RSB (E + DISC), in comparison to exposure with no RSB (ERP). Sixty-seven nonclinical participants completed 15 trials of exposure in which they touched a potentially contaminated stimulus with or without RSB. Behavioral approach tasks were completed at pretreatment, post-treatment, and two-week follow-up to examine changes in subjective distress and degree of behavioral approach. RESULTS: The three conditions were not different on clinical symptoms and behavioral approach at post-treatment and follow-up, indicating that the hypothesized superiority effect of E + DISC was not supported. However, ratings obtained during repeated exposure trials indicated that E + DISC evidenced greater symptom reduction following the removal of RSB. LIMITATIONS: The use of a healthy undergraduate sample and standardization of the exposure procedure. CONCLUSIONS: Although findings were contrary to hypotheses, these data provide added support for the benign role of RSB as compared to conventional exposure. Furthermore, the removal of RSB may lead to more favorable process outcomes during exposure. The theoretical and clinical implications of these findings are discussed, and future directions are provided. PMID- 29587171 TI - Impact of carpal tunnel syndrome on ulnar nerve at wrist: Systematic review. AB - Considerable debate exists in the literature about possible anomalies of ulnar nerve at wrist in carpal tunnel syndrome (CTS). We systematically reviewed the literature about electrophysiologic and morphologic changes of ulnar nerve at wrist in CTS. We carried out a comprehensive search using PubMed from 1963 through October 2017. Data were extracted and the quality of the included studies was evaluated. Twenty-eight studies were selected. Seventy-nine percent of the studies report abnormalities of the ulnar nerve conduction. There was a relation between the median and ulnar nerve conduction in almost all the papers, i.e., conduction impairment of the ulnar nerve increased with increasing severity of median nerve involvement, emerging as a process correlated with damage of the median nerve. Seventy-five percent of ultrasonographic studies report changes of ulnar nerve cross sectional area in CTS. Morphologic and functional changes of the ulnar nerve and/or Guyon canal are reported by 100% of papers addressed to this topic. Several papers quoted in this review have some flaws. The key message of present review is that electrophysiological and morphological changes of the ulnar nerve at the wrist can occur in CTS, although the possibility of an overestimation of the phenomenon needs to be considered. PMID- 29587173 TI - Trends in female and male drunken driving prevalence over thirty years: Triangulating diverse sources of evidence (1985-2015). AB - INTRODUCTION: Women have lower rates of drunken driving than men, but their share of arrests has been climbing since 1985. These trends may stem from changes in women's lives that lead to more drinking and driving, or to greater reductions in male drinking and driving. Alternatively, changes in policy and enforcement that focus on less intoxicated offenders may inadvertently target female-typical offending patterns. This paper tracked male and female drunken driving rates and the DUI sex ratio in the United States from 1985 to 2015 across three data sources. METHODS: The sex ratio and prevalence estimates were derived from official arrest statistics from Uniform Crime Reports, self-reports from the Centers for Disease Control and Prevention, and traffic fatality data from the National Highway and Transportation Safety Administration. Rates were assessed for four age groups (18-20, 21-34, 35-49, and 50-64), and drunken driving trends tested using Augmented Dickey-Fuller time-series methods. RESULTS: Decreases in DUI rates stagnated over the first decade of 2000, but have again begun to decline, according to self-reports and traffic fatality data, for all sex-by-age groups. Still, the gender gap in DUI arrests continues to narrow. From 1990 to the early 2000s, changes in social control that made female DUI more visible narrowed the gender gap in arrests. In more recent years, narrowing of the gap is due primarily to male rates declining more steeply than female rates. CONCLUSION: Results indicate that we need more research to understand why female declines have not kept pace with male declines and perhaps more targeted prevention efforts aimed at women. PMID- 29587172 TI - Client and clinician-rated characteristics of problem gamblers with and without history of gambling-related illegal behaviors. AB - Individuals with gambling disorder are at an elevated risk for engaging in gambling-related illegal behaviors. The present study examined client (N = 88) and clinician ratings (N = 30) of client characteristics associated with a history of gambling-related illegal behaviors. We also examined client characteristics associated with history of arrest for a gambling-related crime. Gambling-related illegal behaviors and arrest were common (57.3% and 23.9%, respectively) in the present sample. Clients of younger age, and those with greater gambling-related financial consequences, lifetime alcohol problems, impulsivity, mood symptoms, and daily living role difficulties were more likely to report gambling-related illegal behaviors. Clients who had been arrested for a gambling-related crime were more likely to report daily living and role functioning difficulties and lifetime alcohol problems. Clinicians rated clients with a history of gambling-related illegal behaviors and/or gambling-related arrests as more impulsive, and clinicians also endorsed higher rates of treatment failure among these clients. Both client and clinician report suggested that clients with a history of illegal behaviors may have a variety of comorbid problems that may be a focus of clinical intervention. PMID- 29587174 TI - Translation and validation study of the Chinese version Iconographical Falls Efficacy Scale-Short Version (Icon-FES). AB - BACKGROUND: The 30-item Iconographical Falls Efficacy Scale (Icon-FES) is the first instrument developed to assess older people's concern about falling using pictures. The short version of Icon-FES (10-item Icon-FES) was translated and adapted to a local Chinese version, and its psychometric properties was evaluated in Chinese older people. METHODS: A forward-backward translation procedure was used, followed by an expert panel review to finalize the 10-item Chinese Icon FES. One hundred and sixteen Hong Kong Chinese older people (65-95 years) were assessed using the 10-item Chinese Icon-FES in conjunction with the Chinese version 7-item Falls Efficacy Scale-International (FES-I (Ch)). RESULTS: Five of the 10 items in the Icon-FES were modified to achieve the conceptual and cultural relevance in local context. The final Chinese Icon-FES had excellent internal consistency (Cronbach's alpha = 0.91) and test-retest reliability (intra-class correlation coefficient ICC = 0.93). High correlation was found between the Chinese Icon-FES and FES-I (Ch) (r = .75, p < .001). Construct validity was supported by its ability to discriminate between groups related to demographic and fall risk factors. CONCLUSIONS: The Chinese Icon-FES is a valid, efficient and easy-to-use instrument for understanding of local Chinese older people's concerns about falling in Hong Kong. PMID- 29587175 TI - Prescription of potentially inappropriate medications to older adults. A nationwide survey at dispensing pharmacies in Japan. AB - OBJECTIVES: Prescriptions to older adults were surveyed to elucidate factors associated with potentially inappropriate medications (PIMs) in Japan. METHODS: Adults aged >=65 years, who were prescribed medications at 585 dispensing pharmacies across Japan, participated (N = 180,673). Data were collected between October 1 and October 31, 2014. RESULTS: Proportion of polypharmacy and that of PIMs increased with age (p < 0.001). Analgesic drugs were most commonly prescribed for the older adults aged 65-74 years, whereas benzodiazepines were prescribed most commonly for those aged over 75 years. A logistic regression analysis revealed that the increase of PIMs was explained by polypharmacy and mainly the use of central nervous systems (CNS) and psychotropic drugs. CONCLUSIONS: The increased prevalence of polypharmacy with age and the common use of CNS and psychotropic medications account for the PIMs in old age in the current nationwide survey. PMID- 29587177 TI - Advances in functional genetic screening with transposons and CRISPR/Cas9 to illuminate cancer biology. AB - Large-scale genome sequencing studies have identified a wealth of mutations in human tumors and have dramatically advanced the field of cancer genetics. However, the functional consequences of an altered gene in tumor progression cannot always be inferred from mutation status alone. This underscores the critical need for complementary methods to assign functional significance to mutated genes in cancer. Transposons are mobile genetic elements that serve as powerful tools for insertional mutagenesis. Over the last decade, investigators have employed mouse models with on-demand transposon-mediated mutagenesis to perform unbiased genetic screens to identify clinically relevant genes that participate in the pathogenesis of human cancer. Two distinct DNA transposon mutagenesis systems, Sleeping Beauty (SB) and PiggyBac (PB), have been applied extensively in vivo and more recently, in ex vivo settings. These studies have informed our understanding of the genes and pathways that drive cancer initiation, progression, and metastasis. This review highlights the latest progress on cancer gene identification for specific cancer subtypes, as well as new technological advances and incorporation of the CRISPR/Cas9 toolbox into transposon-mediated functional genetic studies. PMID- 29587176 TI - Close encounters of the RNAi kind: the silencing life of the adherens junctions. AB - The adherens junction has been historically considered an essential structural component of epithelial tissues. Although primarily discussed as targets of signaling pathways responsible for cell fate and tissue remodeling, they have also emerged as critical signaling regulators in developmental processes or in disease progression. The recent discovery of a functional localized RNA interference (RNAi) machinery at epithelial adherens junctions revealed a new layer of signaling regulation that is directly associated with the structure itself. This and other findings also indicate that our view of the subcellular localization of RNAi requires revisiting. A number of questions emerge regarding the physiological role and the modes of regulation of the junctional RNAi machinery, pointing towards new directions of investigation. PMID- 29587178 TI - Functional network integration and attention skills in young children. AB - Children acquire attention skills rapidly during early childhood as their brains undergo vast neural development. Attention is well studied in the adult brain, yet due to the challenges associated with scanning young children, investigations in early childhood are sparse. Here, we examined the relationship between age, attention and functional connectivity (FC) during passive viewing in multiple intrinsic connectivity networks (ICNs) in 60 typically developing girls between 4 and 7 years whose sustained, selective and executive attention skills were assessed. Visual, auditory, sensorimotor, default mode (DMN), dorsal attention (DAN), ventral attention (VAN), salience, and frontoparietal ICNs were identified via Independent Component Analysis and subjected to a dual regression. Individual spatial maps were regressed against age and attention skills, controlling for age. All ICNs except the VAN showed regions of increasing FC with age. Attention skills were associated with FC in distinct networks after controlling for age: selective attention positively related to FC in the DAN; sustained attention positively related to FC in visual and auditory ICNs; and executive attention positively related to FC in the DMN and visual ICN. These findings suggest distributed network integration across this age range and highlight how multiple ICNs contribute to attention skills in early childhood. PMID- 29587179 TI - Molecular characterization, antibiotic resistance pattern and biofilm formation of Vibrio parahaemolyticus and V. cholerae isolated from crustaceans and humans. AB - Human infection with pathogenic vibrios is associated with contaminated seafood consumption. In the present study, we examined 225 crustaceans collected from retail markets in Egypt. Stool samples from gastroenteritis patients were also examined. Bacteriological and molecular examinations revealed 34 (15.1%) V. parahaemolyticus and 2 (0.9%) V. cholerae from crustaceans, while V. parahaemolyticus isolates were identified in 3 (3%) of the human samples. The virulence-associated genes tdh and/or trh were detected in 5.9% and 100% of the crustacean and human samples, respectively, whereas the two V. cholerae isolates were positive for the ctx and hlyA genes. Antibiotic sensitivity revealed high resistance of the isolates to the used antibiotics and an average MAR index of 0.77. Biofilm formation at different temperatures indicated significantly higher biofilm formation at 37 degrees C and 25 degrees C compared with 4 degrees C. Frequent monitoring of seafood for Vibrio species and their antibiotic, molecular and biofilm characteristics is essential to improve seafood safety. PMID- 29587180 TI - Prioritization of potential drug targets against P. aeruginosa by core proteomic analysis using computational subtractive genomics and Protein-Protein interaction network. AB - Pseudomonas aeruginosa is an opportunistic gram-negative bacterium that has the capability to acquire resistance under hostile conditions and become a threat worldwide. It is involved in nosocomial infections. In the current study, potential novel drug targets against P. aeruginosa have been identified using core proteomic analysis and Protein-Protein Interactions (PPIs) studies. The non redundant reference proteome of 68 strains having complete genome and latest assembly version of P. aeruginosa were downloaded from ftp NCBI RefSeq server in October 2016. The standalone CD-HIT tool was used to cluster ortholog proteins (having >=80% amino acid identity) present in all strains. The pan-proteome was clustered in 12,380 Clusters of Orthologous Proteins (COPs). By using in-house shell scripts, 3252 common COPs were extracted out and designated as clusters of core proteome. The core proteome of PAO1 strain was selected by fetching PAO1's proteome from common COPs. As a result, 1212 proteins were shortlisted that are non-homologous to the human but essential for the survival of the pathogen. Among these 1212 proteins, 321 proteins are conserved hypothetical proteins. Considering their potential as drug target, those 321 hypothetical proteins were selected and their probable functions were characterized. Based on the druggability criteria, 18 proteins were shortlisted. The interacting partners were identified by investigating the PPIs network using STRING v10 database. Subsequently, 8 proteins were shortlisted as 'hub proteins' and proposed as potential novel drug targets against P. aeruginosa. The study is interesting for the scientific community working to identify novel drug targets against MDR pathogens particularly P. aeruginosa. PMID- 29587181 TI - The "Social-mobile autopsy": The evolution of psychological autopsy with new technologies in forensic investigations on suicide. AB - Suicide is a huge deal in general public health, representing the second cause of mortality in young people worldwide. The suicidal setting analysis is usually performed through psychological autopsy, a method of investigation commonly used to study what leads to suicide. Psychological autopsy, though, requires the involvement of family and friends, or the finding of a diary or a suicide note. Nowadays, this is not always possible, especially during adolescence, the more if we consider new categories of people that are more used to live in a web dimension, than in a real one. So, with the advent of a new kind of social system including the web, psychological autopsy, as we know it, is not enough to determine the setting of an event. We here report the case of a 17-year old girl who committed suicide by hanging down from her house, leaving no suicide note. We propose a new investigation method developed through the analysis of phone messages and Facebook profile in order to better reconstruct the event. Although the standing difficulties in reconsidering the intimate motivations leading to such a decision, psychological autopsy nowadays needs to consider also social networks in order to prevent similar situations and even reconstruct the psychological dimension of the fact. We propose a model of Social-mobile autopsy. PMID- 29587182 TI - The role of domain-general cognitive resources in children's construction of a vitalist theory of biology. AB - Some episodes of learning are easier than others. Preschoolers can learn certain facts, such as "my grandmother gave me this purse," only after one or two exposures (easy to learn; fast mapping), but they require several years to learn that plants are alive or that the sun is not alive (hard to learn). One difference between the two kinds of knowledge acquisition is that hard cases often require conceptual construction, such as the construction of the biological concept alive, whereas easy cases merely involve forming new beliefs formulated over concepts the child already has (belief revision, a form of knowledge enrichment). We asked whether different domain-general cognitive resources support these two types of knowledge acquisition (conceptual construction and knowledge enrichment that supports fast mapping) by testing 82 6-year-olds in a pre-training/training/post-training study. We measured children's improvement in an episode involving theory construction (the beginning steps of acquisition of the framework theory of vitalist biology, which requires conceptual change) and in an episode involving knowledge enrichment alone (acquisition of little known facts about animals, such as the location of crickets' ears and the color of octopus blood). In addition, we measured children's executive functions and receptive vocabulary to directly compare the resources drawn upon in the two episodes of learning. We replicated and extended previous findings highlighting the differences between conceptual construction and knowledge enrichment, and we found that Executive Functions predict improvement on the Vitalism battery but not on the Fun Facts battery and that Receptive Vocabulary predicts improvement the Fun Facts battery but not on the Vitalism battery. This double dissociation provides new evidence for the distinction between the two types of knowledge acquisition, and bears on the nature of the learning mechanisms involved in each. PMID- 29587183 TI - Dynamic cognitive models of intertemporal choice. AB - Traditionally, descriptive accounts of intertemporal choice have relied on static and deterministic models that assume alternative-wise processing of the options. Recent research, by contrast, has highlighted the dynamic and probabilistic nature of intertemporal choice and provided support for attribute-wise processing. Currently, dynamic models of intertemporal choice-which account for both the resulting choice and the time course over which the construction of a choice develops-rely exclusively on the framework of evidence accumulation. In this article, we develop and rigorously compare several candidate schemes for dynamic models of intertemporal choice. Specifically, we consider an existing dynamic modeling scheme based on decision field theory and develop two novel modeling schemes-one assuming lexicographic, noncompensatory processing, and the other built on the classical concepts of random utility in economics and discrimination thresholds in psychophysics. We show that all three modeling schemes can accommodate key behavioral regularities in intertemporal choice. When empirical choice and response time data were fit simultaneously, the models built on random utility and discrimination thresholds performed best. The results also indicated substantial individual differences in the dynamics underlying intertemporal choice. Finally, model recovery analyses demonstrated the benefits of including both choice and response time data for more accurate model selection on the individual level. The present work shows how the classical concept of random utility can be extended to incorporate response dynamics in intertemporal choice. Moreover, the results suggest that this approach offers a successful alternative to the dominating evidence accumulation approach when modeling the dynamics of decision making. PMID- 29587184 TI - Recruitment and retention strategies for an urban adolescent study: Lessons learned from a multi-center study of community-based asthma self-management intervention for adolescents. AB - Intervention studies with urban adolescents and families affected by asthma are critical to improving the disproportionate morbidity in this population. Community-based recruitment and retention strategies in a multi-site longitudinal project evaluating an asthma self-management intervention for adolescents are presented. Successful recruitment strategies depended on the geographic and cultural characteristics of each study site. Partnering with providers and groups known to the target population and in-person contact with target population were found effective. Flexibility accommodating modified and new approaches, securing multiple contacts and repeating mailings as well as capitalizing on the benefits of subject payment was critical to achieving long-term subject engagement of 85% in the study. Ongoing monitoring and adjustment of recruitment and retention strategies is recommended. PMID- 29587185 TI - Pregnancy outcomes among women with epilepsy: A retrospective cohort study. AB - OBJECTIVE: The objective of this study was to compare adverse pregnancy outcomes between pregnancies that involve epilepsy and those that do not and are identified as normal for the purposes of this paper. METHODS: A retrospective cohort study was carried out by accessing the maternal-fetal medicine (MFM) database to identify and review records of singleton pregnancies with epilepsy but with no other underlying disease (study group). A parallel group of low-risk pregnancies was randomly allocated as the control group. The adverse outcomes between the two groups were compared. The primary outcomes included rates of spontaneous abortion, small for gestational age (SGA), preterm birth (PTB), low birth weight (LBW), and preeclampsia. RESULTS: From a total of 44,708 deliveries, 148 pregnancies involving mothers with epilepsy and a control group of 1480 normal pregnancies were compared. The rates of spontaneous abortion, PTB, LBW, and cesarean section were slightly but significantly higher in the study group with a relative risk of 6.6 (95% confidence interval (CI): 1.9-23.3), 1.6 (95% CI: 1.1-2.2), 1.6 (95% CI: 1.1-2.3), and 1.5 (95% CI: 1.1-2.1), respectively, whereas other adverse outcomes were comparable. In the subgroup analysis, adverse outcomes tended to be higher in women with active epilepsy. However, only the rates of SGA in the group in which the disorder is active and PTB in the presence of seizures within 6months of conception were significantly increased. CONCLUSIONS: Pregnancies with epilepsy, even in cases with multidisciplinary care and no other risk factors, are still significantly associated with higher adverse outcomes. PMID- 29587186 TI - Role of beta2/3-specific GABA-A receptor isoforms in the development of hippocampus kindling epileptogenesis. AB - OBJECTIVE: Subunit-specific positive allosteric modulators (PAMs) of gamma aminobutyric acid-A (GABA-A) receptors are commonly used to uncover the role of GABA-A receptor isoforms in brain function. Recently, we have designed novel PAMs selective for beta2/3-subunit containing GABA-A receptors (beta2/3-selective PAMs) that are nonbenzodiazepine site-mediated and do not show an alpha-subunit isoform selectivity, yet exhibit anxiolytic efficacy with reduced potential for sedation, cognitive impairment, and tolerance. In this study, we used three novel beta2/3-selective PAMs (2-261, 2-262, and 10029) with differential beta2/3 subunit potency to identify the role of beta2/3-selective receptor isoforms in limbic epileptogenesis. METHODS: Experimental epileptogenesis was induced in mice by daily hippocampus stimulations until each mouse showed generalized (stage 5) seizures. Patch-clamp electrophysiology was used to record GABA-gated currents. Brain levels of beta2/3-selective PAMs were determined for mechanistic correlations. RESULTS: Treatment with the beta2/3-selective PAMs 2-261 (30mg/kg), 2-262 (10mg/kg), and 10029 (30mg/kg), 30min prior to stimulations, significantly suppressed the rate of development of kindled seizure activity without affecting the afterdischarge (AD) signal, indicating their disease-modifying activity. The beta2/3-selective agents suppressed chemical epileptogenesis in the pentylenetetrazol model. Test doses of these agents were devoid of acute antiseizure activity in the kindling model. CONCLUSION: These findings demonstrate that beta2/3-selective PAMs can moderately retard experimental epileptogenesis, indicating the protective role of beta2/3-subunit GABA-A receptor isoforms in the development of epilepsy. PMID- 29587187 TI - Characteristics and healthcare situation of adult patients with tuberous sclerosis complex in German epilepsy centers. AB - OBJECTIVE: The objective of the present study was to collect systematic data on the care of adult patients with tuberous sclerosis complex (TSC) in German epilepsy centers, to describe the characteristics of patients in this age group, and to clarify whether and how the recommended interdisciplinary care is implemented. METHODS: This retrospective survey involved 12 major epilepsy centers in Germany. Aggregated data were collected based on an electronic questionnaire that addressed the sociodemographic data, characteristics of the epilepsy syndromes, and general healthcare setting of adult patients with TSC. RESULTS: The survey included 262 patients (mean age: 36.2+/-9.0years) with TSC, most of whom were reported to live in either a home for persons with a disability (37.0%), a residential care home (6.9%), or with their parents (31.1%). A further 13.0% were self-sustaining, and 8.8% were living with a partner. Most patients presented with focal (49.6%) or multifocal (33.2%) epilepsy, with complex partial, dialeptic, and automotor seizures in 66% of patients and generalized tonic-clonic seizures in 63%. Drug-refractory epilepsy was seen in 78.2% of patients, and 17.6% were seizure-free at the time of the survey. Of the 262 patients, presurgical diagnostics were performed in 27% and epilepsy surgery in 9%, which rendered 50% of these patients seizure-free. Renal screening had been performed in 56.1% within the last three years and was scheduled to be performed in 58.0%. Cases of renal angiomyolipoma were present in 46.9% of the patients. Dermatologic and pulmonary screenings were known to be planned for only few patients. CONCLUSION: Despite TSC being a multisystem disorder causing considerable impairment, every fifth adult patient is self-sustaining or living with a partner. In clinical practice, uncontrolled epilepsy and renal angiomyolipoma are of major importance in adult patients with TSC. Most patients suffer from focal or multifocal epilepsy, but epilepsy surgery is performed in less than 10% of these patients. Interdisciplinary TSC centers may help to optimize the management of patients with TSC regardless of age and ensure early and adequate treatment that also considers the advances in new therapeutic options. PMID- 29587188 TI - Nonconvulsive status epilepticus after cessation of convulsive status epilepticus in pediatric intensive care unit patients. AB - Little is known about pediatric patients suffering from nonconvulsive status epilepticus (NCSE) after convulsive status epilepticus (CSE) cessation. The aim of this study was to identify in pediatric patients the clinical characteristics of NCSE after CSE cessation and the factors that contribute to patient outcomes. Data from clinical features, electroencephalography (EEG) characteristics, neuroimaging findings, treatments, and prognosis were systematically summarized, and the associations between clinical characteristics and prognosis were quantified. Thirty-eight children aged 51days-14years, 2months were identified in the Chongqing Medical University pediatric intensive care unit as having experienced NCSE after CSE cessation between October 1, 2014 and April 1, 2017. All patients were comatose, 15 of whom presented subtle motor signs. The most common underlying etiology was acute central nervous system (CNS) infection. Electroencephalography (EEG) data showed that, during the NCSE period, all patients had several discrete episodes (lasting from 30s to 6h long), and the most common duration was 1-5min. The ictal onset locations were classified as focal (16 patients, 42.1%), multiregional independent (10 patients, 26.3%), and generalized (12 patients, 31.6%). Wave morphologies varied during the ictal and interictal periods. Neuroimaging detected signal abnormalities in the cerebral cortex or subcortex of 33 patients with NCSE (87%), which were classified as either multifocal and consistent with extensive cortical edema (21 patients, 55.3%) or focal (12 patients, 31.6%). Twelve patients were on continuous intravenous phenobarbital, and 31 were on continuous infusion of either midazolam (27 patients) or propofol (4 patients). At least one other antiepileptic drug was prescribed for 32 patients. Three patients were on mild hypothermia therapy. The duration of NCSE lasted <24h for 20 patients and >24h for 18 patients. The mortality rate was 21.1%, and half of the surviving patients had severe neurological morbidity. Our results indicated that EEG monitoring after treatment of CSE was essential to the recognition of persistent seizures. The clinical features, EEG characteristics, and neuroimaging findings varied during the NCSE period. The morbidity is high in pediatric patients who had NCSE after CSE. Convulsive status epilepticus (CSE) duration and neuroimaging results may be related to the prognosis. PMID- 29587189 TI - Synthesis of NiO nanoparticles via a green route using Monsonia burkeana: The physical and biological properties. AB - NiO nanoparticles have emerged as ideal candidates in various fields due to their magnetic, electrical and optical properties. The coupling of plant extracts that have anticancer and antibacterial properties with NiO nanoparticles has increased their usage in the biomedical field. In this work, we report on the novel synthesis of NiO nanoparticles using a local medicinal plant, Monsonia burkenea. The nickel nanoparticles were characterized using Fourier transform infrared spectroscopy (FTIR), Energy dispersive X-ray analysis (EDX), Scanning electron microscope (SEM), High-resolution transmission electron microscope (HRTEM) and X ray diffraction (XRD). FTIR showed that the extraction of the plant phytochemicals was successful and the green synthesized nanoparticles from plants contained the phytochemical groups that are found in the Monsonia burkeana plant. XRD and HRTEM confirmed the successful formation of NiO nanoparticles with an average particle size range of 20 nm. These results were also corroborated by elemental mapping and EDX, where the dominant groups were identified.The Monsonia burkeana NiO particles exhibited selective bactericidal activity against Gram negative strains, such as E. coli and P. aeruginosa. Additionally, cytotoxicity studies showed the materials did not have any anti proliferative effect against A549 lung cancer cells but could be used as potential drug delivery vehicles against human cancers.

AB - Dipeptidyl peptidase 4 (DPP4) is a receptor for MERS-CoV. The soluble form of DPP4 (sDPP4) circulates systematically and can competitively inhibit MERS-CoV entry into host cells. Here, we measured the concentration of sDPP4 in the plasma and sputa of 14 MERS-CoV-infected patients of various degrees of disease severity. The concentration of sDPP4 in the plasma of MERS patients (474.76 +/- 108.06 ng/ml) was significantly lower than those of healthy controls (703.42 +/- 169.96 ng/ml), but there were no significant differences among the patient groups. Interestingly, plasma levels of IL-10 and EGF were negatively and positively correlated with sDPP4 concentrations, respectively. The sDPP4 levels in sputa were less than 300 ng/ml. Viral infection was inhibited by 50% in the presence of more than 8000 ng/ml of sDPP4. Therefore, sDPP4 levels in the plasma of MERS patients are significantly reduced below the threshold needed to exert an antiviral effect against MERS-CoV infection.

AB - Enterovirus (EV)-A71 and Coxsackievirus (CV)-A16 have historically been the major pathogens of hand, foot, and mouth disease (HMFD) in China; however, CV-A6, which had previously received little attention, became the predominant pathogen in 2013, and has remained one of the common pathogens since then. In this work, we conducted a molecular epidemiology study of CV-A6-associated HFMD in Xiamen from 2009 to 2015. The data showed CV-A6 pandemics had a certain periodicity rather than occurring randomly. Evolution analysis based on near-complete VP1 nucleotide sequences showed subgenotype D5 lineage 4 strains account for the persistent outbreak of CV-A6-associated HFMD in China since 2013. Alignment analysis revealed eight candidate amino acid substitutions in VP1, which may provide useful information for the research of CV-A6 virulence enhancement. This study contributed to elucidating the circulation patterns and genetic characteristics of CV-A6 in China; however, further surveillance and intervention in CV-A6 epidemics is recommended.

AB - An optimum copper concentration in environment is highly desired for all forms of life. We have developed an ultrasensitive copper sensor which functions from femto to micro molar concentration accurately (R2 = 0.98). The sensor is based on denatured antibody immunoglobulin G (IgG), immobilized on polyaniline (PAni) which in turn is the coating on the core of an optical fiber. The sensing relies on changes in evanescent wave absorbance in the presence of the analyte. The sensor showed excellent selectivity towards Cu (II) ions over all other metal ions. The sensor was tested with lake and marine water samples to determine unknown concentrations of copper ions and the recovery results were within 90 115%, indicating reasonable accuracy. We further integrated the fiber-optic sensor with a miniaturized hand-held instrumentation platform to develop an accurate and field deployable device which can broadly be applicable to determine Cu (II) concentration in a wide range of systems - natural water bodies, soil as well as blood serum. PMID- 29587193 TI - Development of Cu nanoflowers modified the flexible needle-type microelectrode and its application in continuous monitoring glucose in vivo. AB - A minimally invasive glucose microbiosensor based the flexibly integrated electrode for continuous monitoring glucose in vivo has been developed in this study. This was achieved by coating needle-type microelectrode with Cu nanoflowers, nafion, glucose oxidase (GOD) and polyurethane (PU) membranes, successfully prepared with layer-by-layer deposition. The Cu nanomaterials provided a large specific surface area and electrocatalytic activity for glucose detection. The PU layers as mass-transport limiting membranes significantly enhanced the linearity and stability of sensors. The resulting biosensor exhibited a wide linear range of 0-20 mM, with a good sensitivity of 42.38 nA mM 1 (correlation coefficient r2 was 0.99) and a fast response time of less than 15 s. In vivo implantable experiments using anesthetized rats showed excellent real time response to the variation of blood glucose concentration. And the variation tendency of sensor output was consistent with that using the glucose meter. Overall, the results supported the suitability of this microsensor for measuring rapid changes of glucose in vivo. This work offers a promising approach in implantable device applications related to diabetes management as well as other medical diagnosis. PMID- 29587194 TI - Freeze-dried and re-hydrated liquid crystalline nanoparticles stabilized with disaccharides for drug-delivery of the plectasin derivative AP114 antimicrobial peptide. AB - Liquid crystalline nanoparticles (LCNPs), e.g. cubosomes and hexosomes, are receiving more and more attraction as drug delivery vehicles. Dry powder formulation that forms LCNPs upon hydration can be advantageous to make new routes of administration accessible. In this work, we investigate use of three disaccharides (lactose, trehalose and sucrose) as protective matrices for glycerol monooleate based LCNP forming powders produced by freeze-drying. Phase behavior, particle size and size distributions at the different preparation steps were monitored by small angle x-ray scattering (SAXS) and dynamic light scattering (DLS). Particle appearance was imaged by cryogenic transmission electron microscopy (cryo-TEM). Moreover, the therapeutic relevant antimicrobial peptide AP114 (plectasin derivative) was incorporated in the formulations. Peptide encapsulation and release as well as in vitro antibacterial effect were investigated. Results showed that all freeze-dried powders did form particles with liquid crystalline structure upon hydration. However, a phase transition from the bicontinuous cubic Pn3m to the reversed hexagonal was observed, as a consequence of sugar addition and the freeze-drying procedure. Data indicates that trehalose is the preferred choice of lyo-protectant in order to maintain a mono-modal particle size distribution. In addition, antimicrobial activity of AP114-containing formulations was found to be highest for the formulation containing trehalose. The release kinetics of AP114 from the nanoparticles was strongly affected by the dimensions of the hexagonal phase. Larger dimension of the hexagonal phase, significantly improved the release of AP114 and antimicrobial activity of the formulation. PMID- 29587195 TI - TiO2: Si nanotube/1T-MoSe2 nanosheet hybrids with highly efficient hydrogen evolution catalytic activity. AB - Transition metal dichalcogenides exhibit an excellent catalytic activity for hydrogen evolution reaction and continue to attract many studies. Some heterojunctions are also used to enhance the catalytic activity. In this work, the TiO2 nanotubes/MoSe2 and Si-doped TiO2 NTs/MoSe2 hybrids were synthesized. The MoSe2 in the hybrids exhibited nanosheet morphology and metallic (1T) structure with high conductivity and catalytic activity for hydrogen evolution reaction. Moreover, MoSe2 decoration provided high light absorbance for the hybrids and highly efficient interface-induced effect at the heterojunction. Furthermore, the Si-doping increased specific surface area and hydrophilicity. Thus, the Si-doped TiO2 NTs/MoSe2 hybrids showed remarkably greater photocatalytic and electrocatalytic activities than the nanotubes. PMID- 29587196 TI - Effect of diet and packaging system on the microbial status, pH, color and sensory traits of rabbit meat evaluated during chilled storage. AB - The combined effect of two dietary lipid sources (sunflower vs linseed oil) and three packaging methods (PVC film - BAG, modified atmosphere CO2 20% + 80% O2 - MAP, and vacuum - VAC) on the shelf-life (pH, color, microbial count, sensory traits) of rabbit loins was tested at days 1, 4 and 10 of refrigerated storage. Linseed oil did not adversely affect neither the physical or sensory traits, nor the microbiological quality of rabbit meat throughout the shelf-life trial. The three packaging methods were all similarly effective in maintaining the physical and sensory quality of the meat, irrespective of the different dietary lipid sources and thus different susceptibility to oxidation. MAP and VAC were more effective than BAG in preserving rabbit meat hygienic quality, as highlighted by the microbial count analyzed at day 4 of shelf-life (P < 0.001). At day 10, the microbiological quality didn't differ between MAP and VAC rabbit meat samples. PMID- 29587197 TI - A pilot study demonstrating the efficacy of transcutaneous bilirubin meters to quantitatively differentiate contusions from Congenital Dermal Melanocytosis. AB - OBJECTIVE: Congenital Dermal Melanocytosis (CDM) can be difficult to differentiate from contusions. The need for a prompt and accurate diagnosis is best illustrated in cases where child abuse and maltreatment is of concern. Transcutaneous bilirubin (TCB) spectrophotometry has been well established to measure bilirubin under the skin for jaundice in infants. The use of TCB spectrometry has not been used to identify or differentiate contusions from CDM. We hypothesized that bilirubin, a degradation product of hemoglobin, would be elevated in contusions but not in CDM thus demonstrating the efficacy of a novel diagnostic technique to compliment or improve on physical assessment alone. METHODS: Pilot study with thirty-seven infants and children noted to have CDM and fifty-six infants, children and adults with contusions underwent measurement of their lesion with TCB spectrometry. In each patient, the affected skin was scanned along with the adjacent unaffected native skin allowing an internal control for individual pigment variation. RESULTS: TCB measurements of CDM resulted in lower transcutaneous bilirubin values that were not significantly different from adjacent native skin pigmentation. This was in contrast to cutaneous contusions, which resulted in a higher measured value (mean 5.01 mg/dL) compared to adjacent native tissue (1.24 mg/dL) demonstrating a four-fold increase in measurement at the lesion site (P < 0.001). Direct comparison of a DeltaTCB value (lesion measurement minus the adjacent tissue) demonstrated a significantly higher value in contusions compared to CDM with a mean value of 3.77 and 0.12 mg/dL, respectively (P < 0.001). CONCLUSIONS: TCB Spectrometry as a novel diagnostic technique has the potential to discern contusions from CDM and may therefore have the ability to compliment the use of physical assessment alone. PMID- 29587198 TI - Do emotion regulation difficulties explain the association between executive functions and child physical abuse risk? AB - This study examined the associations between executive functioning problems, emotion regulation difficulties, and risk for perpetrating child physical abuse (CPA). It was hypothesized that: (a) poor executive functions (i.e., working memory problems and inhibition/switching problems) would be associated with higher levels of emotion regulation difficulties and CPA risk; (b) emotion regulation difficulties would be positively associated with CPA risk; and (c) emotion regulation difficulties would partially explain the association between executive functions (i.e., working memory problems and inhibition/switching problems) and CPA risk. To examine these predictions, a sample of 133 general population parents (31% fathers) completed self-report measures of CPA risk, emotion regulation difficulties, working memory problems, and a performance-based measure of inhibition/switching skills. Results revealed that executive functioning problems were linked with emotion regulation difficulties, which in turn were associated with CPA risk. Moreover, emotion regulation difficulties explained the relationship between executive functions (working memory, inhibition/switching) and CPA risk. The final model accounted for 41% of the variance in CPA risk. Although additional research is needed, the present findings suggest that enhancing parents' executive functioning and teaching them effective emotion regulation skills may be important targets for CPA prevention efforts. PMID- 29587199 TI - Modeling the effects of parameter optimization on three bioretention tanks using the HYDRUS-1D model. AB - The operation effects of bioretention on different tanks were investigated through tests and simulations. Three layered bioretention tanks, namely, #1, #2, and #3, were selected for intermittent operation tests. The artificial filler layers of the tanks consisted of mixed fillers of fly ash and sand, blast furnace slag, and planting soil. Models were established by using HYDRUS-1D software based on test results. The sensitivity of model parameters was analyzed through Morris screening method. Results showed that return period, thickness of media layer, and solute concentration in the liquid phase were the parameters that significantly influenced the operation effects. The Nash-Sutcliffe efficiency coefficients of the models were greater than 0.85. The simulation results showed that the reduction effects at different inflow loads were better under low loads than under high loads. The comprehensive reduction rate of pollutant load was 5.22% less under high concentrations than under low concentrations. The comprehensive reduction rates of water and pollutant loads were 35.97% and 20.68% greater, correspondingly, in the 1 year return period than in the 10 year return period. The artificial fillers comprising a mixture of fly ash and sand also showed the optimal reduction effects, with comprehensive reduction rates of 69.33% and 83.08% for water and pollutant load, respectively. The reduction effects of water and pollutants for the #1 tank presented an upward trend, whereas those for the #2 tank showed a downward trend given an increase in planting soil thickness. An increase in media thickness enhanced the reduction effects. The media with 60 cm thickness demonstrated the optimal effect. PMID- 29587200 TI - Urban residents' response to and evaluation of low-carbon travel policies: Evidence from a survey of five eastern cities in China. AB - To address the problems of excessive energy consumption and global climate change, the Chinese government has issued numerous policies to guide urban residents' low-carbon travel behavior. To evaluate the validity of these policies from the perspective of public opinion, this study summarizes 22 policies from the four vantage points of economics, administration, technology, and public information and then measures residents' response to and evaluation of policies based on survey data on 1977 urban residents using stratified random sampling in five cities in eastern China. The results indicate that from the viewpoint of policy response, administrative policies for promoting public transport show the highest degree of response, followed by public information, technological, and economic policies. Specifically, the responses to parking and congestion fee policies are relatively stronger than those to vehicle purchase tax, vehicle and vessel tax, and fuel surcharge policies. Moreover, the responses to fuel surcharge policy are even weaker than car-restriction policies, including license plate number restriction, license-plate lottery, and license-plate auction policies. From the viewpoint of policy evaluation, administrative policies for promoting public transport obtain the highest evaluations, followed by economic and technological policies. Residents' evaluations of car-restriction and public information policies are the lowest. In addition, a four-paradigm model is introduced to illustrate residents' reactions to each policy in terms of response and evaluation. Finally, several implementation strategies, including the anterior, concurrent, optional, core, supporting, and assisting policy options are proposed to guide urban residents' low-carbon travel behavior. PMID- 29587201 TI - Recurrent Rapunzel syndrome - A rare tale of a hairy tail. AB - INTRODUCTION: Rapunzel syndrome is a rare condition predominantly found in trichophagic females that occurs when gastric trichobezoar extends beyond the pylorus and into duodenum, jejunum, ileum or even to colon. There are only five cases reported in literature. This case report has been reported in line with the SCARE criteria. PRESENTATION OF CASE: A 19 year old female, with a history of trichotillomania with trichophagia, who presented with epigastric pain and vomiting for 12 months. She underwent laparotomy ten years back to extract a trichobezoar, which was diagnosed to be Rapunzel syndrome and lack of follow-up resulted in recurrence. Further examination and imaging showed a large trichobezoar extending into small intestine. She underwent gastrotomy and entrerotomy and extraction of hairball. DISCUSSION: In a trichophagic female with abdominal pain, nausea and vomiting, and abdominal mass, diagnosis is done by ultrasound, CT scan and upper gastrointestinal endoscopy. Small trichobezoars can be removed endoscopically. Large (>20 cms)acutely symptomatic trichobezoars, especially when accompanied by Rapunzel syndrome, must be removed surgically by gastrotomy and enterotomy is required if impacted extension is present. Long-term surgical and psychiatric follow-up with psychotherapy and cognitive behavioural therapy along with selective serotonin reuptake inhibitors are critical to prevent recurrences. CONCLUSION: Although Rapunzel syndrome is an extremely rare disease, it should be considered when diagnosing young women, especially those with a history of trichophagia or trichotillomania. After the surgical removal of trichobezoars by laparotomy, long-term follow-up combined with psychiatric consultation is recommended to prevent recurrences. PMID- 29587202 TI - Stattic inhibits RANKL-mediated osteoclastogenesis by suppressing activation of STAT3 and NF-kappaB pathways. AB - Tofacitinib, a small molecule JAK inhibitor, has been widely used to reduce inflammation and inhibit progression of bone destruction in rheumatoid arthritis. STAT3, a downstream signaling molecule of JAK, plays a key role in the activation of signaling in response to inflammatory cytokines. Thus, targeting STAT3 may be an inspiring strategy for treating osteoclast-related diseases such as rheumatoid arthritis. In this study, we first investigated the effects of Stattic, a STAT3 inhibitor, on receptor activator of NF-kappaB ligand (RANKL)-mediated osteoclastogenesis. Stattic inhibited osteoclast differentiation and bone resorption in RANKL-induced RAW264.7 cells in a dose-dependent manner. Stattic also suppressed RANKL-induced upregulation of osteoclast-related genes tartrate resistant acid phosphatase, matrix metalloproteinase 9, cathepsin K, RANK, tumor necrosis factor receptor-associated factor 6, and osteoclast-associated receptor in RAW264.7 cells. Moreover, Stattic exhibited an inhibitory effect on cell proliferation and cell cycle progression at higher dosages. At the molecular level, Stattic inhibited RANKL-induced activation of STAT3 and NF-kappaB pathways, without significantly affecting MAPK signaling. In addition, Stattic inhibited RANKL-induced expression of osteoclast-related transcription factors c Fos and NFATc1. Importantly, Stattic also prevented bone loss caused by ovariectomy. Together, our data confirm that Stattic restricts osteoclastogenesis and bone loss by disturbing RANKL-induced STAT3 and NF-kappaB signaling. Thus, Stattic represents a novel type of osteoclast inhibitor that could be useful for conditions such as osteoporosis and rheumatoid arthritis. PMID- 29587203 TI - Inhibitor of Bruton's tyrosine kinases, PCI-32765, decreases pro-inflammatory mediators' production in high glucose-induced macrophages. AB - Accumulating evidence has shown that macrophages play a vital role in development and pathogenesis of diabetic nephropathy (DN) by secreting inflammatory cytokines. Although Bruton's tyrosine kinases (Btk) is a biologically important molecule implicated in immune regulation, the role of Btk in high glucose (HG) stimulated inflammatory response in macrophages and the mechanism involved need further investigation. In our study, we used bone marrow-derived macrophages (BMMs) to investigate the involvement of Btk on HG-induced inflammatory cytokines expression and to explore the underlying mechanisms. We found that high glucose induced phosphorylation of Btk, MAPKs and NF-kappaB, and the expression of downstream inflammation cytokines monocyte chemo-attractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta). Btk inhibitor (PCI-32765) not only down-regulated ERK1/2 phosphorylation and NF kappaB activation, but also decreased the secretion of MCP-1, TNF-alpha and IL 1beta in HG-treated BMMs. These results indicate that Btk plays an important role in HG-induced inflammatory cytokines expression and that PCI-32765 may be used as an immunoregulatory agent against hyperglycemia-induced inflammatory response in DN. PMID- 29587204 TI - Leukotriene D4 induces cellular senescence in osteoblasts. AB - Aging is associated with the development of osteoporosis, in which cellular senescence in osteoblasts plays a key role. Leukotriene D4 (LTD4), an important cysteinyl leukotriene (cysLT), is a powerful pro-inflammatory mediator formed from arachidonic acid. However, little information regarding the effects of LTD4 on the pathogenesis of osteoporosis has been reported before. In the present study, we defined the physiological roles of LTD4 in cellular senescence in osteoblasts. Our results indicate that LTD4 treatment decreased the expression of SIRT1 in a dose-dependent manner in MC3T3-E1 osteoblastic cells. Additionally, LTD4 significantly increased the expression of p53, p21 and plasminogen activator inhibitor-1 (PAI-1). LTD4 was also found to elevate the activity of beta galactosidase (SA-beta-Gal) but to prevent BrdU incorporation. Our results indicate that cysteinyl leukotriene receptor 1 (cysLT1R) could be detected in MC3T3-E1 osteoblastic cells at both the mRNA and protein levels. However, cysLT2R was not expressed in these cells. Interestingly, we found that knockdown of cysLT1R or use of the selective cysLT1R antagonist montelukast abolished the LTD4 induced reduction in SIRT1 and increase in p53, p21, and PAI-1. Notably, knockdown of cysLT1R by transfection with cysLT1R siRNA or treatment with montelukast attenuated the LTD4-induced increase in SA-beta-Gal activity. Our study shows for the first time that LTD4 has a significant impact on cellular senescence in osteoblasts. PMID- 29587205 TI - Affective impairments in binge drinking: Investigation through emotional facial expression decoding. AB - OBJECTIVE: Binge drinking, an excessive alcohol consumption pattern frequently observed in young people, is known to be associated with psychological and cerebral deficits. While cognitive dysfunctions have been widely investigated, emotional abilities have scarcely been explored. Such an exploration would however offer a more exhaustive understanding of the deficits associated with binge drinking, as well as of the possible transition towards alcohol-dependence. METHODS: 46 young adults (23 binge drinkers, 12 women; 23 control participants, 12 women) were recruited among university students. They performed an emotional recognition task consisting of the visual decoding of six basic emotions (i.e. anger, contempt, disgust, fear, happiness, and sadness). Accuracy scores and detection thresholds were collected for each emotion. RESULTS: Binge drinkers showed lower performance than control participants for the decoding of all emotions and increased detection threshold, this later reflecting less ability to capture an emotion. Binge drinking is thus associated with a need for higher emotional intensity to perform correct detection. Moreover, these emotional difficulties appear specifically related to alcohol consumption. CONCLUSION: These findings reinforce previous experimental evidence of altered emotional processing among binge drinkers, and extend these results for various emotional contents. They support the hypothesis of a continuum between binge drinking and alcohol-dependence, in which massive emotional impairments have been documented. Indeed, these impairments could be involved in the onset and maintenance of excessive alcohol consumption, notably through the established relationship between emotional deficits and social distress.

PMID- 29587208 TI - Modulation of transcription of genes related to the hypothalamic-pituitary gonadal and the hypothalamic-pituitary-adrenal axes in zebrafish (Danio rerio) embryos/larvae by androstenedione. AB - This study aimed to determine the effects of Androstenodione (AED) on the transcriptional expression of genes involved in the hypothalamic-pituitary gonadal (HPG) and the hypothalamic-pituitary-adrenal (HPA) axes in the zebrafish embryos/larvae. Zebrafish embryos were exposed to 0, 4.0, 45.0, 487.0, and 980.0 ng/L of AED from the day of fertilization to 144 h post fertilization (hpf), during which the transcriptional profiles of key genes related to the HPG and HPA axes were examined daily using quantitative real-time PCR. The AED exposure significantly up-regulated several receptor signaling pathways and the key genes involved in various steps of the steroidogenic pathways were also affected. In addition, the AED exposure could significantly modulate the transcriptional profiles of the other target genes related to hypothalamic and pituitary hormones. The findings of this study suggest that AED, at environmentally relevant concentrations, affects the adrenal endocrine systems and the reproduction of zebrafish by interrupting the HPG and HPA axes. PMID- 29587209 TI - The behaviours of nurses that increase student accountability for learning in clinical practice: An integrative review. AB - OBJECTIVE: To identify nurses' behaviours that promote student accountability for learning in clinical practice. BACKGROUND: Health care services are experiencing significant strain in meeting clinical education requirements of increasing numbers of nursing students enrolled in undergraduate nursing programs. Internationally, the transition to university based education for nurses has seen the emergence of issues for busy clinicians trying to manage increasing workloads with responsibility for student learning. An understanding of what types of supervisor behaviours promote student accountability for learning, may support clinicians to more effectively manage their dual roles of clinical care and student support. DESIGN: An integrative approach was adopted for this review. DATA SOURCES: A search of the Cumulative Index of Nursing and Allied Health Literature, Pubmed, Scopus and Embase was undertaken, limited to articles published between 2000 and March 2017. REVIEW METHODS: Whittemore and Knafls' (2005) framework for conducting integrative reviews was used to ensure a methodological and rigorous approach. RESULTS: Nine studies were considered. Behaviours emerged in relation to four themes including: belongingness associated with a genuine partnership; empowerment and increasing student self-efficacy; trust linked to increasing and staged independence; and balancing clinical and educational requirements. CONCLUSION: Behaviours of nurses significantly influence students' accountability for learning and accordingly, their ability to be adequately prepared for professional nursing practice. Understanding behaviours that impact on students' approach to clinical placement can guide nurses in their approach to facilitating student learning, in particular, behaviours that increase student responsibility and independence over the continuum of clinical education. PMID- 29587210 TI - Variation in mercury concentration in juvenile Magellanic penguins during their migration path along the Southwest Atlantic Ocean. AB - The vulnerability of seabirds related to their migratory dynamics is frequently linked to environmental problems along the migration path. In this context, Magellanic penguins (Sphenicus magellanicus) seem to be vulnerable to an extensive range of environmental disturbances during their northward migration along the Atlantic waters of South America, which include by catch, marine debris ingestion, overfishing and environmental contamination. In this study, we investigate mercury accumulation in muscle and hepatic tissues of juveniles penguins collected along the Brazilian coast during three migratory seasonal years (2006, 2008 and 2012) and three areas along a latitudinal gradient. We found significant differences in Hg levels across the years, with higher hepatic Hg levels found in tissues of penguins sampled in 2008. The higher Hg levels in samples of penguins from 2008 might be attributed to variations in body condition or Hg uptake, associated with the trophic imbalance linked to an extreme El Nino event during that year. Significant differences in Hg accumulation across the latitudinal areas were also observed. The penguins sampled at the farthest area from the breeding ground presented the higher levels of Hg and also the poorest body condition. Body condition and other traits may influence the levels of chemical pollutants and decrease the migratory success rate in the juvenile age phase, compromising population dynamics. PMID- 29587211 TI - Tracing perfluoroalkyl substances (PFASs) in soils along the urbanizing coastal area of Bohai and Yellow Seas, China. AB - With the shift of fluorine chemical industry from developed countries to China and increasing demand for fluorine chemical products, occurrence of perfluoroalkyl substances (PFASs) in production and application areas has attracted more attention. In this study, 153 soil samples were collected from 21 cities along the urbanizing coastal area of the Bohai and Yellow Seas. PFASs in this area were relatively higher, compared with other study areas. The concentrations ranged from 2.76 to 64.0 ng g-1, and those in most sites were between 2.76 and 13.9 ng g-1, with a predominance of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Among the 21 coastal cities, contaminations of PFASs in Zibo, Nantong and Binzhou were elevated, which was likely affected by local fluorine chemical plants, equipment manufacturing and chemical industry, respectively. The total emissions of PFOA and PFOS were similar, with amount of 4431 kg and 4335 kg, respectively. Atmospheric deposition was the largest source, accounting for 93.2% of total PFOA and 69.6% of PFOS, respectively. In addition, due to application of aqueous film-forming foams (AFFFs) and sulfluramid, disposal of sewage sludge and stacking of solid waste, emission of PFOA and PFOS to soil was 1617 kg, accounting for 9.29% of the whole China. In general, pollution in Jiangsu, Shandong and Tianjin was more serious than those in Liaoning and Hebei, which was consistent with industrialization level and size of industrial sectors emitting PFASs. PMID- 29587212 TI - First evaluation of the use of down feathers for monitoring persistent organic pollutants and organophosphate ester flame retardants: A pilot study using nestlings of the endangered cinereous vulture (Aegypius monachus). AB - Raptor feathers have been increasingly used to assess pollutants in ecotoxicological monitoring studies. However, the suitability of down feathers to detect pollutants has not yet been investigated. In this study, concentrations of persistent organic pollutants (POPs) and organophosphate ester flame retardants (OPEs) were assessed in down and juvenile contour feathers of Spanish cinereous vulture (Aegypius monachus) nestlings (circa 73 days old) and contaminant concentrations were compared between both types of feathers from the same individuals. Concentrations of polychlorinated biphenyls (PCBs: 1.30-6.16 ng g-1 dw feather), polybrominated diphenyl ethers (PBDEs: 0.23-1.35 ng g-1 dw feather), p,p'-dichlorodiphenyldichloroethylene (pp-DDE: 0.09-6.10 ng g-1 dw feather) and tris (1-chloro-2-propyl) phosphate (TCiPP: 0.86-48.96 ng g-1 dw feather) were significantly higher in down than in contour feathers. In contrast, contour feathers showed higher levels of the more volatile POP, lindane (0.25-3.12 ng g-1 dw feather). Concentrations of hexachlorobenzene (HCB) and OPEs (except TCiPP) were similar between the two types of feathers. By showing high accumulation of the most persistent POPs investigated, down feathers presented a contamination profile similar to that previously described in raptor eggs. As these feathers grow during the first days of a vulture chicks life, they probably reflect the contaminant burden of the chick due to maternal transfer to the egg. Overall, the present study provides the first indication that down feathers may be useful for biomonitoring studies. Further research is needed to confirm whether nestling down feathers reflect the concentrations in the egg. PMID- 29587213 TI - Stereoselective bioaccumulation of chiral PCB 91 in earthworm and its metabolomic and lipidomic responses. AB - Stereoselective bioaccumulation, elimination, metabolomic and lipidomic responses of earthworm Eisenia fetida exposed to chiral polychlorinated biphenyl (PCB) 91 in an earthworm-soil system were investigated. Preferential bioaccumulation of ( )-PCB 91 and elimination of (+)-PCB 91 were observed following 50 and 500 MUg/kgdwt exposures. Enantiomer fraction (EF) values decreased over time during the uptake and elimination periods. Metabolomics and lipidomics techniques based on ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) revealed significant changes in 108 metabolites after earthworms exposure to (+)-, (-)-, and (+/-)-PCB 91, compared to control groups. Forty two of these metabolites were identified as amino acids, nucleosides, fatty acids, dicarboxylic acids, vitamins or others. Lysophospholipids including six lysophosphatidylcholines (LPC), six lysophosphatidylethanolamine (LPE), eight lysophosphatidylinositol (LPI) and five lysophosphatidylserine (LPS) were also differentially expressed between exposure and control groups. Alterations in the levels of metabolites and lipids indicated stereoselective effects of chiral PCB 91 on earthworm amino acid, energy, and nucleotide metabolism, neurodevelopment and gene expression. Overall, the effects of (+)-PCB 91 were more pronounced than that of (-)- and (+/-)-PCB 91. PMID- 29587215 TI - Global review and analysis of erythromycin in the environment: Occurrence, bioaccumulation and antibiotic resistance hazards. AB - Environmental observations of antibiotics and other pharmaceuticals have received attention as indicators of an urbanizing global water cycle. When connections between environment and development of antibiotic resistance (ABR) are considered, it is increasingly important to understand the life cycle of antibiotics. Here we examined the global occurrence of erythromycin (ERY) in: 1. wastewater effluent, inland waters, drinking water, groundwater, and estuarine and coastal systems; 2. sewage sludge, biosolids and sediments; and 3. tissues of aquatic organisms. We then performed probabilistic environmental hazard assessments to identify probabilities of exceeding the predicted no-effect concentration (PNEC) of 1.0 MUg L-1 for promoting ABR, based on previous modeling of minimum inhibitory concentrations and minimal selective concentrations of ERY, and measured levels from different geographic regions. Marked differences were observed among geographic regions and matrices. For example, more information was available for water matrices (312 publications) than solids (97 publications). ERY has primarily been studied in Asia, North America and Europe with the majority of studies performed in China, USA, Spain and the United Kingdom. In surface waters 72.4% of the Asian studies have been performed in China, while 85.4% of the observations from North America were from the USA; Spain represented 41.9% of the European surface water studies. Remarkably, results from PEHAs indicated that the likelihood of exceeding the ERY PNEC for ABR in effluents was markedly high in Asia (33.3%) followed by Europe (20%) and North America (17.8%). Unfortunately, ERY occurrence data is comparatively limited in coastal and marine systems across large geographic regions including Southwest Asia, Eastern Europe, Africa, and Central and South America. Future studies are needed to understand risks of ERY and other antibiotics to human health and the environment, particularly in developing regions where waste management systems and treatment infrastructure are being implemented slower than access to and consumption of pharmaceuticals is occurring. PMID- 29587214 TI - Assessment of airborne polycyclic aromatic hydrocarbons in a megacity of South China: Spatiotemporal variability, indoor-outdoor interplay and potential human health risk. AB - Although a number of studies have assessed the occurrence of atmospheric polycyclic aromatic hydrocarbons (PAHs) in indoor environment, few studies have systemically examined the indoor-outdoor interplay of size-dependent particulate PAHs and potential health risk based on daily lifestyles. In the present study, size-dependent particle and gaseous samples were collected both indoors and outdoors within selected schools, offices and residences located in three districts of Guangzhou, China with different urbanization levels during the dry and wet weather seasons. Results from measurements of PAHs showed that higher total PAH concentrations occurred in residential areas than in other settings and in indoor than in outdoor environments. Compositional profiles and size distribution patterns of particle-bound PAHs were similar indoors and outdoors, predominated by 4-and 5-ring PAHs and the 0.56-1.0 MUm particle fraction. Statistical analyses indicated that outdoor sources may have contributed to 38 99% and 62-100% of the variations for indoor particle-bound and gaseous PAH concentrations, respectively. Incremental life cancer risk (ILCR) from human exposure to indoor and outdoor PAHs based on different lifestyles followed the order of adults > children > adolescents > seniors. All average ILCR values for four age groups were below the lower limit of the Safe Acceptable Range (10-6). In addition, the ILCR value for adults (average: 7.2 * 10-7; 95% CI: 5.4 * 10-8 2.5 * 10-6), estimated from outdoor air PAH levels with 24-h exposure time, was significantly higher than our assessment results (average: 5.9 * 10-7; 95% CI: 6.3 * 10-8-1.9 * 10-6), suggesting the significance of assessing human inhalation exposure risks of indoor and outdoor PAHs in urban air based on daily lifestyles. PMID- 29587216 TI - Emission and health risk assessment of volatile organic compounds in various processes of a petroleum refinery in the Pearl River Delta, China. AB - The process-specific emission of volatile organic compounds (VOCs) from a petroleum refinery in the Pearl River Delta, China was monitored to assess the health risk from VOCs to workers of this refinery. Over 60 VOCs were detected in the air samples collected from various sites in the refining, basic chemical, and wastewater treatment areas of the refinery using gas chromatography-mass spectrometry/flame ionization detection. The health risks of VOCs to the refinery workers were assessed using US Environmental Protection Agency (US EPA) and American Conference of Governmental Industrial Hygienists (ACGIH) methods. Monte Carlo simulation and sensitivity analysis were implemented to assess the uncertainty of the health risk estimation. The emission results showed that C5-C6 alkanes, including 2-methylpentane (17.6%), 2,3-dimethylbutane (15.4%) and 3 methylpentane (7.7%), were the major VOCs in the refining area. p-Diethylbenzene (9.3%), 2-methylpentane (8.1%) and m-diethylbenzene (6.8%) were dominant in the basic chemical area, and 2-methylpentane (20.9%), 2,3-dimethylbutane (11.4%) and 3-methylpentane (6.5%) were the most abundant in the wastewater treatment area. For the non-cancer risk estimated using the US EPA method, the total hazard ratio in the basic chemical area was the highest (3.1 * 103), owing to the highest level of total concentration of VOCs. For the cancer risk, the total cancer risks were very high, ranging from 2.93 * 10-3 (in the wastewater treatment area) to 1.1 * 10-2 (in the basic chemical area), suggesting a definite risk. Using the ACGIH method, the total occupational exposure cancer risks of VOCs in the basic chemical area were the highest, being much higher than those of refining and wastewater treatment areas. Among the areas, the total occupational exposure risks in the basic chemical and refining areas were >1, which suggested a cancer threat to workers in these areas. Sensitivity analysis suggested that improving the accuracy of VOC concentrations themselves in future research would advance the health risk assessment. PMID- 29587217 TI - Evaluation of different methods for assessing bioavailability of DDT residues during soil remediation. AB - Compared to the total chemical concentration, bioavailability is a better measurement of risks of hydrophobic organic contaminants (HOCs) to biota in contaminated soil or sediment. Many different bioavailability estimation methods have been introduced to assess the effectiveness of remediation treatments. However, to date the different methods have rarely been evaluated against each other, leading to confusions in method selection. In this study, four different bioavailability estimation methods, including solid phase microextraction (SPME) and polyethylene passive sampling (PE) aiming to detect free chemical concentration (Cfree), and Tenax desorption and isotope dilution method (IDM) aiming to measure chemical accessibility, were used in parallel to estimate in bioavailability of DDT residues (DDXs) in a historically contaminated soil after addition of different black carbon sorbents. Bioaccumulation into earthworm (Eisenia fetida) was measured concurrently for verification. Activated carbon or biochar amendment at 0.2-2% decreased earthworm bioaccumulation of DDXs by 83.9 99.4%, while multi-walled carbon nanotubes had a limited effect (4.3-20.7%). While all methods correctly predicted changes in DDX bioavailability after black carbon amendment, passive samplers offered more accurate predictions. Predicted levels of DDXs in earthworm lipid using the estimated bioavailability and empirical BCFs matched closely with the experimentally derived tissue concentrations. However, Tenax and IDM overestimated bioavailability when the available DDX levels were low. Our findings suggested that both passive samplers and bioaccessibility methods can be used in assessing remediation efficiency, presenting flexibility in method selection. While accessibility-oriented methods offer better sensitivity and shorter sampling time, passive samplers may be more advantageous because of their better performance and computability for in situ deployment. PMID- 29587218 TI - Culture and transplantation of spermatogonial stem cells. AB - The spermatogonial transplantation technique was developed by Dr. Ralph Brinster in 1994. Transplanted spermatogonial stem cells (SSCs) produce germ cell colonies after microinjection into the seminiferous tubules of infertile mice. This technique provided the first functional assay for SSCs. Although it became possible to produce transgenic animals using this transplantation technique in 2001, the lack of SSC culture systems prevented efficient genetic manipulation. To overcome this problem, a long-term SSC culture technique was developed in 2003. Cultured SSCs, designated as germline stem cells, allow drug selection of transfected SSCs, and knockout mice were produced in 2006. Using these techniques, it is now possible to address basic biological questions of SSC biology. They also open up new possibilities for male germline manipulation. In this review, we will briefly summarize our findings on SSCs and discuss unresolved issues that remain to be addressed. PMID- 29587219 TI - Specific-age group sex estimation of infants through geometric morphometrics analysis of pubis and ischium. AB - Sex determination of unknown individuals is one of the primary goals of Physical and Forensic Anthropology. The adult skeleton can be sexed using both morphological and metric traits on a large number of bones. The human pelvis is often used as an important element of adult sex determination. However, studies carried out about the pelvic bone in subadult individuals present several limitations due the absence of sexually dimorphic characteristics. In this study, we analyse the sexual dimorphism of the immature pubis and ischium bones, attending to their shape (Procrustes residuals) and size (centroid size), using an identified sample of subadult individuals composed of 58 individuals for the pubis and 83 for the ischium, aged between birth and 1year of life, from the Granada osteological collection of identified infants (Granada, Spain). Geometric morphometric methods and discriminant analysis were applied to this study. The results of intra- and inter-observer error showed good and excellent agreement in the location of coordinates of landmarks and semilandmarks, respectively. Principal component analysis performed on shape and size variables showed superposition of the two sexes, suggesting a low degree of sexual dimorphism. Canonical variable analysis did not show significant changes between the male and female shapes. As a consequence, discriminant analysis with leave-one-out cross validation provided low classification accuracy. The results suggested a low degree of sexual dimorphism supported by significant sexual dimorphism in the subadult sample and poor cross-validated classification accuracy. The inclusion of centroid size as a discriminant variable does not imply a significant improvement in the results of the analysis. The similarities found between the sexes prevent consideration of pubic and ischial morphology as a sex estimator in early stages of development. The authors suggest extending this study by analysing the different trajectories of shape and size in later ontogeny between males and females. PMID- 29587220 TI - The purinergic P2X7 ion channel receptor-a 'repair' receptor in bone. AB - A strong skeleton relies on adaptation to varying physical demands and on maintenance of the bone tissue in order to avoid accumulation of micro-damage. In bone, the purinergic P2X7 ion channel receptor is expressed on both cells of the stromal lineage such as the bone forming osteoblasts and the mechano-sensing osteocytes and on cells belonging to the immune-related monocyte-macrophage lineage, the bone resorbing osteoclasts. Recent studies have demonstrated that the receptor plays important roles in the anabolic responses to mechanical loading on bone and, together with the pannexin1 hemi-channel, in the process of initiating bone remodeling in response to micro-damage. Thus, the receptor is crucial in skeletal mechano-transduction and in the continuous repair process. However, under pathophysiological conditions such as diabetes with high glucose concentrations or glucocorticoid-treatment the receptor is downregulated thus blunting the important effects it has for maintaining a healthy and strong skeleton. PMID- 29587221 TI - Structure-activity relationships of 2, 4-disubstituted pyrimidines as dual ERalpha/VEGFR-2 ligands with anti-breast cancer activity. AB - Both ERalpha and VEGFR-2 are important targets for cancer therapies. Here a series of 2, 4-disubstituted pyrimidine derivatives were designed, synthesized and evaluated as dual ERalpha/VEGFR-2 ligands. Most of the derivatives exhibited potent activities in both enzymatic and cellular assays. Structure-activity relationship studies showed that a hydrogen-bonding interaction in the head section is important factors for the enhancement of ERalpha-binding affinity. The most potent compound II-9OH, an analog of 2-(4-hydroxylphenyl)pyrimidine, was 19 fold more efficacious than tamoxifen in MCF-7 cancer cells and exhibited the best ERalpha binding affinity (IC50 = 1.64 MUM) as well as excellent VEGFR-2 inhibition (IC50 = 0.085 MUM). Furthermore, this dual targeted compound II-9OH exerted significantly antiestrogenic property via suppressing the expression of progesterone receptor (PgR) mRNA in MCF-7 cells and also showed obvious in vivo angiogenesis inhibitory effects in CAM assay. An induction of apoptosis and a decrease in cell migration, accompanied by transduction inhibition of Raf 1/MAPK/ERK pathway, were observed in MCF-7 cells after treatment with II-9OH, suggesting that II-9OH is a promising candidate for the development of multifunctional agents targeting ERalpha and VEGFR-2 in the therapy of some breast cancers. PMID- 29587222 TI - Occupational extremely low frequency magnetic fields (ELF-MF) exposure and hematolymphopoietic cancers - Swiss National Cohort analysis and updated meta analysis. AB - PURPOSE: Previous studies have examined risks of leukaemia and selected lymphoid malignancies in workers exposed to extremely low frequency magnetic fields (ELF MF). Most studies evaluated hematolymphopoietic malignancies as a combined category, but some analyses suggested that effects may be contained to some specific leukaemia or lymphoma subtypes, with inconsistent results. METHODS: We examined exposure to ELF-MF and mortality 1990-2008 from different types of hematolymphopoietic cancers in the Swiss National Cohort, using a job exposure matrix for occupations recorded at censuses 1990 and 2000. We analysed 3.1 million workers exposed at different levels to ELF-MF: ever-high, only-medium, only-low exposure using Cox proportional hazard models. We evaluated risk of death from acute myeloid leukaemia (AML), chronic myeloid leukaemia, lymphoid leukaemia, diffuse large B-cell lymphomas, follicular lymphoma, Waldenstrom's macroglobulinemia, multiple myeloma and Hodgkin lymphoma. RESULTS: Mortality from hematolymphopoietic cancers was not associated with exposure to ELF-MF with the exception of an increase in ever-high exposed men of myeloid leukaemias (HR 1.31, 95% CI 1.02-1.67), and AML (HR 1.26, 95%CI 0.93-1.70). If workers had been high exposed during their vocational training and at both censuses, these HR increased to 2.24 (95%CI 0.91-5.53) and 2.75 (95%CI 1.11-6.83), respectively. CONCLUSIONS: Our analysis provided no convincing evidence for an increased risk of death from a range of hematolymphopoietic cancers in workers exposed to high or medium levels of ELF magnetic fields. However, we observed an increased risk of acute myeloid leukaemia in workers exposed to high levels for a longer duration. Observed risks are in line with meta-analysed previous reports on ELF-MF exposure and AML risk, with a summary relative risk of 1.21 (95%CI 1.08-1.37). PMID- 29587223 TI - Hallmarks of Alzheimer disease are evolving relentlessly in Metropolitan Mexico City infants, children and young adults. APOE4 carriers have higher suicide risk and higher odds of reaching NFT stage V at <= 40 years of age. AB - Exposures to fine particulate matter (PM2.5) and ozone (O3) above USEPA standards are associated with Alzheimer's disease (AD) risk. Metropolitan Mexico City (MMC) residents have life time exposures to PM2.5 and O3 above USEPA standards. We investigated AD intra and extracellular protein aggregates and ultrastructural neurovascular pathology in 203 MMC residents age 25.36 +/- 9.23 y. Immunohistochemical methods were used to identify AT8 hyperphosphorilated tau (Htau) and 4G8 (amyloid beta 17-24). Primary outcomes: staging of Htau and amyloid, per decade and cumulative PM2.5 (CPM2.5) above standard. Apolipoprotein E allele 4 (APOE4), age and cause of death were secondary outcomes. Subcortical pretangle stage b was identified in an 11month old baby. Cortical tau pre tangles, neurofibrillary tangles (NFT) Stages I-II, amyloid phases 1-2, Htau in substantia nigrae, auditory, oculomotor, trigeminal and autonomic systems were identified by the 2nd decade. Progression to NFT stages III-V was present in 24.8% of 30-40 y old subjects. APOE4 carriers have 4.92 times higher suicide odds (p = 0.0006), and 23.6 times higher odds of NFT V (p < 0.0001) v APOE4 non carriers having similar CPM2.5 exposure and age. Age (p = 0.0062) and CPM2.5 (p = 0.0178) were significant for developing NFT V. Combustion-derived nanoparticles were associated with early and progressive damage to the neurovascular unit. Alzheimer's disease starting in the brainstem of young children and affecting 99.5% of young urbanites is a serious health crisis. Air pollution control should be prioritised. Childhood relentless Htau makes a fundamental target for neuroprotective interventions and the first two decades are critical. We recommend the concept of preclinical AD be revised and emphasize the need to define paediatric environmental, nutritional, metabolic and genetic risk factor interactions of paramount importance to prevent AD. AD evolving from childhood is threating the wellbeing of our children and future generations. PMID- 29587224 TI - Application of ultra high-performance liquid chromatography tandem mass spectrometry to investigate the regioselective glucuronidation of icaritin in vitro. AB - Icaritin is one of the Epimedium products with various biological activities. In the present study, we developed a rapid, reliable and robust UHPLC-MS/MS method to simultaneously determine unconjugated icaritin and its multiple glucuronides (icaritin-3-glucuronide, icaritin-7-glucuronide and icaritin-3,7-diglucuronide) in microsomal incubation systems, and applied it to study icaritin regioselective glucuronidation in vitro. We identified the involvement of human UDP glucuronosyltransferase (UGT) isoforms in icaritin metabolism and further studied the kinetic profiles of icaritin glucuronidation using pooled human liver microsomes (HLMs), pooled rat liver microsomes (RLMs), pooled human intestine microsomes (HIMs) and UGTs, respectively. We also evaluated regioselective glucuronidation of icaritin by UGT isoforms and conducted time-dependent experiment to elucidate the metabolic pathways for icaritin clearance. Catalytic efficiency of microsomes is determined according to rank orders of total intrinsic clearance (CLint): CLint,HLM (24.19 mL/mg/min) > CLint,RLM (13.15 mL/mg/min) > CLint,HIM (6.43 mL/mg/min). Besides, icaritin glucuronidation is mediated by multiple enzymes, with UGT1A1 the principal metabolizing enzyme (total CLint,UGT1A1 = 6.38 mL/mg/min). As for the regioselectivity, except for UGT1A8 and UGT2B7, most UGT isoforms exhibit preference for the position of 3-OH on icaritin structure. Moreover, time-dependent conversion from monoglucuronides to diglucuronide indicate that icaritin-3,7-diglucuronide may be the final metabolite from icaritin elimination. PMID- 29587225 TI - Hydrogen deuterium exchange reveals changes to protein dynamics of recombinant human erythropoietin upon N- and O- desialylation. AB - Recombinant human erythropoietin (EPO) is a therapeutic glycoprotein widely used for treating anemia. EPO glycans carry extensive sialylation and the level of the modification is known to affect receptor binding, protein stability and pharmacokinetics. Nonetheless, a detailed understanding of the effects of sialylation on EPO conformation and dynamics is still lacking. Here we investigate the changes to EPO dynamics following enzymatic trimming of terminal sialic acid by amide hydrogen deuterium exchange mass spectrometry (HDX-MS). The results revealed that desialylation enhances structural flexibility near the glycosylation sites, with greater effects observed around the O-glycosylation site relative to the N-glycosylation sites. The affected regions are surface exposed loops connecting the helix bundle, which do not appear to reduce the thermostability of the molecule as revealed from melting measurement. Our findings demonstrate the feasibility of HDX-MS technique in deciphering the function of specific type of glycosylation that can provide novel insights into the role of sialylation on protein therapeutics. PMID- 29587226 TI - Comparative metabolites profiles of osthole in normal and osteoporosis rats using liquid chromatography quadrupole time-of-flight mass spectrometry. AB - Osthole is a derivative of coumnarin, which has been used to treat several diseases, including osteoporosis. To investigate the metabolite profile of osthole in osteoporosis rats was utilized to understand its underlying mechanisms of its anti-osteoporosis effect. In this study, plasma samples were collected from normal and osteoporosis rats after oral administration of osthole and analyzed to identify the metabolites of osthole by high performance liquid chromatography quadrupole time-of-flight mass spectrometry. By comparing the molecular weight and MS fragmentation of the metabolites with those of parent drug and reference standards, a total of 36 metabolites in plasma were identified. Demethylation, hydroxylation, hydroxymethylene loss and reduction, and subsequent glucuronidation, methylation and sulfation were the major metabolic pathways of osthole in both normal and osteoporosis rats. A specific hydration metabolic pathway was found in osteoporosis rats. These results provided a meaningful basis for studying the underlying mechanism of the anti osteoporosis effect of osthole. PMID- 29587227 TI - Characterization of product-related low molecular weight impurities in therapeutic monoclonal antibodies using hydrophilic interaction chromatography coupled with mass spectrometry. AB - Traditional SDS-PAGE method and its modern equivalent CE-SDS method are both widely applied to assess the purity of therapeutic monoclonal antibody (mAb) drug products. However, structural identification of low molecular weight (LMW) impurities using those methods has been challenging and largely based on empirical knowledges. In this paper, we present that hydrophilic interaction chromatography (HILIC) coupled with mass spectrometry analysis is a novel and orthogonal method to characterize such LMW impurities present within a purified mAb drug product sample. We show here that after removal of N-linked glycans, the HILIC method separates mAb-related LMW impurities with a size-based elution order. The subsequent mass measurement from a high-resolution accurate mass spectrometer provides direct and unambiguous identification of a variety of low abundance LMW impurities within a single LC-MS analysis. Free light chain, half antibody, H2L species (antibody possessing a single light chain) and protein backbone-truncated species can all be confidently identified and elucidated in great detail, including the truncation sites and associated post-translational modifications. It is worth noting that this study provides the first example where the H2L species can be directly detected in a mAb drug product sample by intact mass analysis without prior enrichment. PMID- 29587228 TI - The effect of NaCl stress on photosynthetic efficiency and lipid production in freshwater microalga-Scenedesmus obliquus XJ002. AB - Rapid industrialization and population growth have increased the world's energy demands, resulting in a shortage of conventional fossil fuels. Thus, there is an urgent need to develop sustainable and renewable forms of energy. Microalgae have emerged as a potential feedstock for biofuel production. Under stress conditions, lipid production is enhanced in algal cells due to changes in the lipid biosynthetic pathways that produce neutral lipids. In this study, we examined the physiological and biochemical effects of salinity stress (0.00, 0.01, 0.10, 0.15, 0.20M) on the freshwater microalga Scenedesmus obliquus XJ002. We found that the biomass and the content of chlorophyll a, b and carotenoids decreased with increasing NaCl concentration. NaCl stress damaged the oxygen evolving complex (OEC) and the PSII (photosystem II) reaction center and subsequently suppressed electron transport at the donor and receptor sides of the reaction center, influencing the absorption, transfer, and application of light energy. Additionally, the total lipid content of cells was significantly increased under NaCl stress treatment. The highest lipid content (32.26%) was found in cells cultured in the presence of 0.20M NaCl, which was about 2.52-fold higher than that of cells grown in medium lacking NaCl (12.82%). In addition to providing insight into the physiological and biochemical responses of S. obliquus XJ002 to salinity stress, these findings show that lipid production, and hence biofuel feedstock production, can be boosted by adjusting salt levels in the growth medium. PMID- 29587229 TI - Representing a large region with few sites: The Quality Index approach for field studies. AB - Many environmental studies require the characterization of a large geographical region using a range of representative sites amenable to intensive study. A systematic approach to selecting study areas can help ensure that an adequate range of the variables of interest is captured. We present a novel method of selecting study sites representing a larger region, in which the region is divided into subregions, which are characterized with relevant independent variables, and displayed in mathematical variable space. Potential study sites are also displayed this way, and selected to cover the range in variables present in the region. The coverage of sites is assessed with the Quality Index, which compares the range and standard deviation of variables among the sites to that of the larger region, and prioritizes sites that are well-distributed (i.e. not clumped) in variable space. We illustrate the method with a case study examining relationships between agricultural land use, physiography and stream phosphorus (P) export, in which we selected several variables representing agricultural P inputs and landscape susceptibility to P loss. A geographic area of 110,000km2 was represented with 11 study sites with good coverage of four variables representing agricultural P inputs and transport mechanisms taken from commonly available geospatial datasets. We use a genetic algorithm to select 11 sites with the highest possible QI and compare these, post-hoc, to our sites. This approach reduces subjectivity in site selection, considers practical constraints and easily allows for site reselection if necessary. This site selection approach can easily be adapted to different landscapes and study goals, as we provide an algorithm and computer code to reproduce our approach elsewhere. PMID- 29587230 TI - Oxidative stress and DNA damage in zebrafish liver due to hydroxyapatite nanoparticles-loaded cadmium. AB - This study investigated the acute and sub-acute toxicity responses in zebrafish following their exposure to hydroxyapatite-loaded cadmium nanoparticles (nHAP Cd). The results indicate that cadmium chloride (Cd2+), 20 nm nHAP-Cd (nHAP20 Cd), and 40 nm nHAP-Cd (nHAP40-Cd) caused toxicity in zebrafish; the toxicity levels were in the following order: Cd2+ > nHAP20-Cd > nHAP40-Cd. Furthermore, nHAP-Cd showed level II grade of acute toxicity in zebrafish; the gradation was done on the guidelines of the Organization for Economic Co-operation and Development 203. We also found that Cd2+ ions and nHAP-Cd affected the malondialdehyde (MDA) levels and membrane permeability of zebrafish livers; these effects were compliant with the changes in antioxidant levels. The results of enzyme assays indicate the following notion: following the exposure of zebrafish to 0.12-0.93 mg/L nHAP-Cd, the activities of peroxidase, superoxide dismutase, and catalase enzymes increased significantly. Moreover, the content of anti superoxide anion also increased substantially. This increasing trend of enzymatic activity was observed until the concentration of nHAP-Cd reached 1.86 mg/L nHAP Cd. By increasing the concentration of both Cd2+ and nHAP-Cd, we found that levels of DNA damage had increased substantially in zebrafish liver; this effect was visualized by performing comet assay. PMID- 29587231 TI - Neonicotinoid pesticides in drinking water in agricultural regions of southern Ontario, Canada. AB - Because of the persistence and solubility of neonicotinoid insecticides (NNIs), there is concern that these compounds may contaminate sources of drinking water. The objective of this project was to evaluate the distribution of NNIs in raw and treated drinking water from selected municipalities that draw their water from the lower Great Lakes in areas of southern Ontario, Canada where there is high intensity agriculture. Sites were monitored using Polar Organic Chemical Integrative Samplers (POCIS) and by collecting grab samples at six drinking water treatment plants. Thiamethoxam, clothianidin and imidacloprid were detected in both POCIS and grab samples of raw water. The frequency of detection of NNIs was much lower in treated drinking water, but some compounds were still detected at estimated concentrations in the low ng L-1 range. Thiamethoxam was detected in one grab sample of raw drinking water at a mean concentration of 0.28 MUg L-1, which is above the guidelines for drinking water recommended in some jurisdictions, including the European Union directive on pesticide levels <0.1 MUg L-1 in water intended for human consumption. Further work is required to determine whether contamination of sources of drinking water with this class of insecticides is a global problem in agricultural regions. PMID- 29587232 TI - Influence of microplastics on the accumulation and chronic toxic effects of cadmium in zebrafish (Danio rerio). AB - As the accumulation of microplastics (MPs) in the environment continues to rise, more concerns focus on the health risk of combined exposure to MPs and other contaminants. The aim of this study is to investigate the influences of MPs on the tissue-accumulation of cadmium (Cd) in zebrafish and explore the related chronic toxic effects induced by combined exposure of Cd and MPs. After co exposure to MPs and Cd for 3 weeks, 20 and 200 MUg/L MPs increased the accumulation of Cd in zebrafish livers (46% and 184%), guts (10% and 25%) and gills (9% and 46%). The Cd accumulation was gill > gut > liver. Comprehensive analyzes of biochemical biomarkers, histopathological observation and functional gene expression firstly demonstrated that the presence of MPs enhanced the toxicity of Cd on zebrafish and the combined exposure caused oxidative damage and inflammation in zebrafish tissues. Collectively, our results highlight the chronic effects of combined exposure to MPs and heavy metals. PMID- 29587233 TI - Characteristics of suspended particulate matter in a typical slow-moving river of northern China: Insight into its structure and motion behavior. AB - To investigate the characteristics of suspended particulate matter (SPM) in rivers of northern China, SPM was collected from 20 sampling sites within the severely polluted slow-moving Ziya River Mainstream (ZRM) and from 20 sampling sites within the less-polluted fast-moving Luanhe River (LR) between October and November of 2016. Physical and chemical attributes of river water from the ZRM and LR were measured; the microstructure, specific surface area and particle size of the SPM were also determined. The SPM had thicker organic coated layers on inorganic particles within the ZRM, compared with the LR, indicating strong interaction of the SPM with the water column. Along the ZRM length, these organic coated layers evolved, first plugging particle pores and then increasing in volume, causing the specific surface area to decrease at first and then increase. The presence of organic coated layers on inorganic particles greatly changed their particle size, density and inducing changes in their motion behavior. Such changes in SPM microstructure were most apparent in the slow-moving polluted ZRM. Given that SPM can adsorb contaminants, such as phosphorus and heavy metals, onto its surfaces and transport them downstream, these changes could have a profound impact on both sediment transport and river ecosystem function. Our results suggest we need to reevaluate our previous river management measures for slow moving polluted rivers. PMID- 29587234 TI - The pro-inflammatory effects of particulate matter on epithelial cells are associated with elemental composition. AB - BACKGROUND: Adverse health effects of particulate matter (PM) vary with chemical composition; however, evidence regarding which elements are the most detrimental is limited. The roof space area provides an open and stable environment for outdoor PM to settle and deposit. Therefore, this study used roof space PM samples as a proxy of residential cumulative exposure to outdoor air pollution to investigate their pro-inflammatory effects on human lung cells and the contribution of the endotoxin and chemical content. METHODS: Roof space PM samples of 36 different homes were collected and analysed using standardised techniques. We evaluated cytotoxicity and cytokine production of BEAS-2B cells after PM exposure using MTS and ELISA, respectively. Principle component analysis (PCA) and linear regression analyses were employed to assess the associations between cytokine production and the PM components. RESULTS: PM caused significant time- and dose-dependent increases in cellular cytokine production (p < 0.05). PCA identified four factors that explained 68.33% of the variance in the chemical composition. An increase in Factor 1 (+Fe, +Al, +Mn) score and a decrease in Factor 2 (-Ca, +Pb, +PAH) score were associated with increased interleukin (IL)-6 (Factor 1; p = 0.010; Factor 2; p = 0.006) and IL-8 (Factor 1; p = 0.003; Factor 2; p = 0.020) production, however, only the association with Factor 1 was evident after correcting for endotoxin and particle size. CONCLUSIONS: Our study provides novel insight into the positive associations between pro-inflammatory effects of roof space PM samples with Fe, Al and Mn levels. PMID- 29587235 TI - Toxicological interactions between mycotoxins from ubiquitous fungi: Impact on hepatic and intestinal human epithelial cells. AB - Aflatoxin B1 (AFB1), deoxynivalenol (DON), fumonisin B1 (FB1) and ochratoxin A (OTA) are toxic fungal metabolites co-occurring naturally in the environment. This study aimed to evaluate the toxicological interactions of these mycotoxins concerning additive, antagonistic and synergistic toxicity towards human cells. The theoretical biology-based Combination index-isobologram method was used to evaluate the individual and binary effect of these toxins and determine the type of the interaction using as models Caco-2 (intestinal) and HepG2 (hepatic) cells. Cytotoxicity was assessed using the MTT test at the concentrations of 0.625-20 MUM for all the compounds. DON exerted the highest toxicity toward both cells, OTA and AFB1 also showed a dose-effect response, whereas no toxicity was verified for FB1. Synergism or antagonism effects occurred when exposing AFB1-DON and AFB1 OTA on Caco-2 cells at higher or lower concentrations, respectively; while DON OTA showed synergism throughout all inhibition levels. Concerning HepG2, AFB1-DON exerted a strong synergism, regardless of the level; whereas AFB1-OTA had slight synergism/nearly additive effect; and, OTA-DON had a moderate antagonism/nearly additive effect. Synergistic strengths as high as a dose reduction index of 10 for AFB1-DON were observed in hepatic cells. Taken together our findings indicate that the toxicological effects differ regarding the type of mycotoxins used for combinations and the stronger synergistic effect was observed for mixtures containing DON in both cells. Therefore, even though DON has not been classified as to its carcinogenicity to humans, this mycotoxin may present a serious threat to health, mainly when co-occurring in the environment. PMID- 29587236 TI - Ciprofloxacin-metal complexes -stability and toxicity tests in the presence of humic substances. AB - The co-contamination of ciprofloxacin (CIP) with metal ions results in alteration of CIP mobility, antimicrobial activity and distribution/development of the antibiotic-resistance genes. In this study, the stability of five CIP-Me complexes [Me = Al(III), Co(II), Cu(II), Fe(III), Mg] was investigated in the presence of humic substances (HS) at two temperatures 18 +/- 2 degrees C and 4 +/- 1 degrees C for seven days period. The most stable complexes were CIP-Al, CIP-Cu, and CIP-Co with the stability constants (K) at 18 degrees C 35.5 +/- 1.4 11.5 +/- 1.5 and 11.7 +/- 1.5 respectively. At lower temperature (4 degrees C), the stability constants decreased: 1-fold for CIP-Al, 14-fold for CIP-Co and 2 fold for CIP-Cu. The presence of humic substances decreased the stability of complexes. The chemical reactions of Fe3+ in water at circumneutral pH resulted in stability alteration. The formation of CIP-Mg complexes at lower temperatures and in the presence of HS was limited. In ultrapure water, CIP-Me complexes exhibit higher toxicity towards Gram-negative Enterobacter aeruginosa (ranged between 0.125 and 0.5 MUg/ml). However, the presence of HS reduced the antimicrobial activity of CIP-Me complexes by at least 2-fold. Gram-positive representative, Bacillus subtilis was not affected by the presence of metal ions and/or HS. The toxicity toward B. subtilis for the complexes was equal to toxicity of CIP alone (MIC = 0.25 MUg/ml). This suggested the different susceptibility to CIP and its complexes. PMID- 29587237 TI - Isothermal microcalorimetry - A quantitative method to monitor Trypanosoma congolense growth and growth inhibition by trypanocidal drugs in real time. AB - Trypanosoma congolense is a protozoan parasite that is transmitted by tsetse flies, causing African Animal Trypanosomiasis, also known as Nagana, in sub Saharan Africa. Nagana is a fatal disease of livestock that causes severe economic losses. Two drugs are available, diminazene and isometamidium, yet successful treatment is jeopardized by drug resistant T. congolense. Isothermal microcalorimetry is a highly sensitive tool that can be used to study growth of the extracellular T. congolense parasites or to study parasite growth inhibition after the addition of antitrypanosomal drugs. Time of drug action and time to kill can be quantified in a simple way by real time heat flow measurements. We established a robust protocol for the microcalorimetric studies of T. congolense and developed mathematical computations in R to calculate different parameters related to growth and the kinetics of drug action. We demonstrate the feasibility and benefit of the method exemplary with the two standard drugs, diminazene aceturate and isometamidium chloride. The method and the mathematical approach can be translated to study other pathogenic or non-pathogenic cells if they are metabolically active and grow under axenic conditions. PMID- 29587238 TI - Zingerone ameliorates cisplatin-induced ovarian and uterine toxicity via suppression of sex hormone imbalances, oxidative stress, inflammation and apoptosis in female wistar rats. AB - Cisplatin (CP) is a widely used chemotherapeutic drug, effective against a variety of solid tumours, though its utility is limited due to its multiple organ toxicity. Zingerone (ZO), one of the most important components of dry ginger root, has several pharmacological activities, such as antioxidant, anti inflammatory and anti-apoptotic properties. This study aimed to investigate the ameliorative effect of ZO on CP-induced ovarian and uterine toxicity in female rats. The rats were subjected to a prophylactic oral treatment of ZO (25 and 50 mg/kg body weight) for seven days to measure the protective effect against ovarian and uterine toxicity induced by a single (i.p.) of CP (7 mg/kg body weight) on the first day whereas the rats were sacrificed on the eighth day. The results showed that ZO decreased the serum FSH hormone level, increased the serum E2 hormone level, and also maintained the ovarian and uterine histological architecture and integrity. In addition, ZO obviously increased the measured activity of antioxidant enzymes (SOD, CAT and GPx) and the GSH content, and significantly reduced MDA levels. ZO was able to reduce the levels of the inflammatory markers NF-kappaB, TNF-alpha, IL-1beta, IL-6, COX-2 and iNOS in CP induced ovarian and uterine damage. It also inhibited apoptosis and reduced oxidative DNA damage markers by the downregulation of caspase-3 and 8-OHdG expression coupled with an upregulated Bcl-2 level. The results indicate that ZO may be beneficial in ameliorating CP-induced oxidative stress, sex hormone imbalances, inflammation and apoptosis in ovarian and uterine tissues of female rats. PMID- 29587239 TI - Enhanced expression of SRPK2 contributes to aggressive progression and metastasis in prostate cancer. AB - Serine/Arginine-Rich Protein-Specific Kinase-2 (SRSF protein kinase-2, SRPK2) is up-regulated in multiple human tumors. However, the expression, function and clinical significance of SRPK2 in prostate cancer (PCa) has not yet been understood. We therefore aimed to determine the association of SRPK2 with tumor progression and metastasis in PCa patients in our present study. The expression of SRPK2 was detected by some public datasets and validated using a clinical tissue microarray (TMA) by immunohistochemistry. The association of SRPK2 expression with various clinicopathological characteristics of PCa patients was subsequently statistically analyzed based on the The Cancer Genome Atlas (TCGA) dataset and clinical TMA. The effects of SRPK2 on cancer cell proliferation, migration, invasion, cell cycle progression, apoptosis and tumor growth were then respectively investigated using in vitro and in vivo experiments. First, public datasets showed that SRPK2 expression was greater in PCa tissues when compared with non-cancerous tissues. Statistical analysis demonstrated that high expression of SRPK2 was significantly correlated with a higher Gleason Score, advanced pathological stage and the presence of tumor metastasis in the TCGA Dataset (all P < 0.01). Similar correlations between SRPK2 and a higher Gleason Score or advanced pathological stage were also identified in the TMA (P < 0.05). Kaplan-Meier curve analyses showed that the biochemical recurrence (BCR)-free time of PCa patients with SRPK2 high expression was shorter than for those with SRPK2 low expression (P < 0.05). Second, cell function experiments in PCa cell lines revealed that enhanced SRPK2 expression could promote cell proliferation, migration, invasion and cell cycle progression but suppress tumor cell apoptosis in vitro. Xenograft experiments showed that SRPK2 promoted tumor growth in vivo. In conclusion, our data demonstrated that SRPK2 may play an important role in the progression and metastasis of PCa, which suggests that it might be a potential therapeutic target for PCa clinical therapy. PMID- 29587240 TI - Tea polysaccharide inhibits RANKL-induced osteoclastogenesis in RAW264.7 cells and ameliorates ovariectomy-induced osteoporosis in rats. AB - BACKGROUND AND PURPOSE: Tea drinking has positive effects on bone health and may prevent and treat osteoporosis, especially in older and postmenopausal women. Tea polysaccharide (TPS) is a major bioactive constituent in tea. Despite its profound effects on human health, whether TPS has anti-osteoporotic effects remains largely unknown. As such, we investigated the anti-osteoporotic effects of TPS. METHODS: In vitro, TPS effects on osteoclastogenesis were examined using osteoclast precursor RAW264.7 cells. TPS effects on osteoclastogenesis-related expression of marker genes and proteins were determined by gene expression and immunoblotting analyses, respectively. For in vivo studies, 12-week-old female Wistar rats were divided randomly into a sham-operated group (sham) and four ovariectomized (OVX) subgroups: OVX with vehicle (model) and OVX with low-, medium-, and high-dose TPS (0.32, 0.64 and 1.28 g/kg body weight/day, respectively). TPS was administered intragastrically to rats for 13 weeks. Body weight, blood biochemical parameters, organ weight, organ coefficients, femoral length, bone mineral density (BMD), biomechanical properties, and bone microarchitecture were documented. RESULTS: TPS inhibited osteoclast differentiation significantly and dose-dependently, and its inhibitory effect was not due to toxicity to RAW264.7 cells. TPS suppressed expression of osteoclastogenesis-related marker genes and proteins significantly. In in vivo studies, medium-dose TPS treatment ameliorated OVX-induced calcium loss significantly. Low-dose TPS treatment decreased the activity of acid phosphatase (ACP) in OVX rats significantly. In addition, TPS treatment improved other blood biochemical parameters and femoral biomechanical properties to a certain extent. More importantly, TPS treatment ameliorated bone microarchitecture in OVX rats strikingly because of increased cortical bone thickness and trabecular bone area in the femur. CONCLUSION: TPS can inhibit receptor activator nuclear factor-kappa B ligand (RANKL)-induced osteoclastogenesis in RAW264.7 cells and ameliorate ovariectomy-induced osteoporosis in rats. PMID- 29587241 TI - Butyrate, a dietary fiber derivative that improves irinotecan effect in colon cancer cells. AB - A diet rich in fiber is associated with a low risk of developing colorectal cancer. Dietary fiber fermentation by intestinal microflora results in the production of butyrate, which has been reported as a chemopreventive agent and a histone deacetylase inhibitor (HDACi). Irinotecan is used as second-line treatment and induces adverse effects with serious life-threatening toxicities in at least 36% of patients. Our study intends to find a synergy that could improve the efficacy and decrease the toxicity of chemotherapy. Results demonstrate that milimolar concentrations of butyrate has an anti-proliferative effect in all three colon cancer cell lines under study, leading to a decrease on cell viability, expression of P21, P53 and beta-catenin, being able to modulate P glycoprotein activity and to induce apoptosis by modulation of BAX/BCL-2 ratio. Combined therapy has a cytotoxic potential, resulting in a synergistic effect, and allows a reduction in irinotecan concentration needed to reduce IC50. This potential was verified in terms of cell viability and death, cell cycle and expression of P21 and P53. Butyrate and irinotecan act synergistically in the three cancer cell lines, despite the different genetic background and location, and inhibited tumor growth in a xenograft model. Butyrate is able to influence the mechanism of LS1034 cell line chemoresistance. Butyrate in combination with chemotherapeutic agents has an important role for the treatment of colorectal cancer. Such understanding can guide decisions about which patients with colorectal cancer may benefit from therapy with butyrate demonstrating the important role of diet in colorectal cancer treatment. PMID- 29587242 TI - Anthocyanins as a potential pharmacological agent to manage memory deficit, oxidative stress and alterations in ion pump activity induced by experimental sporadic dementia of Alzheimer's type. AB - Anthocyanins (ANT) are polyphenolic flavonoids with antioxidant and neuroprotective properties. This study evaluated the effect of ANT treatment on cognitive performance and neurochemical parameters in an experimental model of sporadic dementia of Alzheimer's type (SDAT). Adult male rats were divided into four groups: control (1 ml/kg saline, once daily, by gavage), ANT (200 mg/kg, once daily, by gavage), streptozotocin (STZ, 3 mg/kg) and STZ plus ANT. STZ was administered via bilateral intracerebroventricular (ICV) injection (5 MUl). ANT were administered after ICV injection for 25 days. Cognitive deficits (short-term memory and spatial memory), oxidative stress parameters, and acetylcholinesterase (AChE) and Na+-K+-ATPase activity in the cerebral cortex and hippocampus were evaluated. ANT treatment protected against the worsening of memory in STZ-induced SDAT. STZ promoted an increase in AChE and Na+-K+-ATPase total and isoform activity in both structures; ANT restored this change. STZ administration induced an increase in lipid peroxidation and decrease in the level of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), in the cerebral cortex; ANT significantly attenuated these effects. In the hippocampus, an increase in reactive oxygen species (ROS), nitrite and lipid peroxidation levels, and SOD activity and a decrease in CAT and GPx activity were seen after STZ injection. ANT protected against the changes in ROS and antioxidant enzyme levels. In conclusion, the present study showed that treatment with ANT attenuated memory deficits, protected against oxidative damage in the brain, and restored AChE and ion pump activity in an STZ-induced SDAT in rats. PMID- 29587243 TI - Serum calcium levels and neuropsychological performance in depression and matched healthy controls: Reversal of correlation a marker of the aging cognitive clock? AB - BACKGROUND: Major depressive disorder (MDD) is associated with cognitive impairment, that might be related to disturbed calcium homeostasis. Calcium related processes have also been implicated in age related cognitive decline. Since serum calcium and brain interstitial fluids maintain long-term equilibrium under normal physiological states, serum calcium levels could affect neuronal and hence cognitive function. High serum calcium has been associated with cognitive decline in geriatric populations, whereas evidence for MDD and healthy populations is less consistent. METHODS: Differences in neuropsychological (NPS) performance and their relationship with serum calcium (total, ionized, total to ionized ratio) in (partially) remitted MDD patients (n = 59) and healthy controls (HC) (n = 59) individually matched for age, gender and education (age-range 19-60 years) were examined. Modulation of study parameters and their interaction by the factor age was investigated, with subgroups young and old divided at median = 37 years. Participants provided blood samples and completed an extensive NPS test battery. RESULTS: MDD showed significantly poorer NPS performance compared to HC. Serum calcium associated positively with NPS performance in HC and negatively in MDD for entire age-range samples. While younger MDD and HC showed positive NPS calcium correlations, older MDD and HC exhibited negative NPS-calcium correlations ('correlation reversal'). Age had a significant effect on cognition and ionized calcium and interacted with illness-status, with an exaggerated influence on cognition in MDD compared to HC. CONCLUSIONS: The results place calcium 'correlation reversal' to early middle-age time window, which may be accelerated for MDD and highlight the central role of calcium pathways in normal and pathological cognitive aging. PMID- 29587244 TI - Epigenetic regulation of vascular NADPH oxidase expression and reactive oxygen species production by histone deacetylase-dependent mechanisms in experimental diabetes. AB - Reactive oxygen species (ROS) generated by up-regulated NADPH oxidase (Nox) contribute to structural-functional alterations of the vascular wall in diabetes. Epigenetic mechanisms, such as histone acetylation, emerged as important regulators of gene expression in cardiovascular disorders. Since their role in diabetes is still elusive we hypothesized that histone deacetylase (HDAC) dependent mechanisms could mediate vascular Nox overexpression in diabetic conditions. Non-diabetic and streptozotocin-induced diabetic C57BL/6J mice were randomized to receive vehicle or suberoylanilide hydroxamic acid (SAHA), a pan HDAC inhibitor. In vitro studies were performed on a human aortic smooth muscle cell (SMC) line. Aortic SMCs typically express Nox1, Nox4, and Nox5 subtypes. HDAC1 and HDAC2 proteins along with Nox1, Nox2, and Nox4 levels were found significantly elevated in the aortas of diabetic mice compared to non-diabetic animals. Treatment of diabetic mice with SAHA mitigated the aortic expression of Nox1, Nox2, and Nox4 subtypes and NADPH-stimulated ROS production. High concentrations of glucose increased HDAC1 and HDAC2 protein levels in cultured SMCs. SAHA significantly reduced the high glucose-induced Nox1/4/5 expression, ROS production, and the formation malondialdehyde-protein adducts in SMCs. Overexpression of HDAC2 up-regulated the Nox1/4/5 gene promoter activities in SMCs. Physical interactions of HDAC1/2 and p300 proteins with Nox1/4/5 promoters were detected at the sites of active transcription. High glucose induced histone H3K27 acetylation enrichment at the promoters of Nox1/4/5 genes in SMCs. The novel data of this study indicate that HDACs mediate vascular Nox up-regulation in diabetes. HDAC inhibition reduces vascular ROS production in experimental diabetes, possibly by a mechanism involving negative regulation of Nox expression. PMID- 29587246 TI - Effect of different designs of ankle-foot orthoses on gait in patients with stroke: A systematic review. AB - BACKGROUND: Ankle foot orthoses (AFOs) are used to improve the gait of patients with stroke. RESEARCH QUESTION: The current review aimed at evaluating the efficacy of different designs of AFOs and comparison between them on the gait parameters of individuals with hemiplegic stroke. METHODS: The search strategy was based on the population intervention comparison outcome (PICO) method. A search was performed in PubMed, ISI Web of Knowledge, Scopus, Science Direct, and Google Scholar databases. RESULTS: A total of 27 articles were found for the final evaluation. All types of AFOs had positive effects on ankle kinematic in the first rocker and swing phases, but not on knee kinematics in the swing phase, hip kinematics or the third rocker function. All trials, except two, assessed immediate or short-term effects only. The articulated passive AFO compared with the non-articulated passive AFO had better effects on some aspects of the gait of patients with hemiplegia following stroke, more investigations are needed in this regard though. SIGNIFICANCE: An ankle-foot orthosis can immediately improve the dropped foot in the stance and swing phases. The effects of long-term usage and comparison among the different types of AFOs need to be evaluated. PMID- 29587245 TI - Mitochondrial ROS cause motor deficits induced by synaptic inactivity: Implications for synapse pruning. AB - Developmental synapse pruning refines burgeoning connectomes. The basic mechanisms of mitochondrial reactive oxygen species (ROS) production suggest they select inactive synapses for pruning: whether they do so is unknown. To begin to unravel whether mitochondrial ROS regulate pruning, we made the local consequences of neuromuscular junction (NMJ) pruning detectable as motor deficits by using disparate exogenous and endogenous models to induce synaptic inactivity en masse in developing Xenopus laevis tadpoles. We resolved whether: (1) synaptic inactivity increases mitochondrial ROS; and (2) chemically heterogeneous antioxidants rescue synaptic inactivity induced motor deficits. Regardless of whether it was achieved with muscle (alpha-bungarotoxin), nerve (alpha latrotoxin) targeted neurotoxins or an endogenous pruning cue (SPARC), synaptic inactivity increased mitochondrial ROS in vivo. The manganese porphyrins MnTE-2 PyP5+ and/or MnTnBuOE-2-PyP5+ blocked mitochondrial ROS to significantly reduce neurotoxin and endogenous pruning cue induced motor deficits. Selectively inducing mitochondrial ROS-using mitochondria-targeted Paraquat (MitoPQ) recapitulated synaptic inactivity induced motor deficits; which were significantly reduced by blocking mitochondrial ROS with MnTnBuOE-2-PyP5+. We unveil mitochondrial ROS as synaptic activity sentinels that regulate the phenotypical consequences of forced synaptic inactivity at the NMJ. Our novel results are relevant to pruning because synaptic inactivity is one of its defining features. PMID- 29587247 TI - The nanostructure of porous cobalt coatings deposited by magnetron sputtering in helium atmosphere. AB - In this work, (scanning) transmission electron microscopy has been used to study the nanostructure of porous cobalt coatings obtained by magnetron sputtering using helium as process gas. This nanostructure consists of closed pores of different nanometric size (about 4-20 nm) that are distributed all over a nanocrystalline Co matrix and filled with the deposition gas. Spatially resolved electron energy-loss spectroscopy analysis was applied to measure and map, with high lateral resolution, the relevant physical properties (density, pressure and He-K edge shift) of helium trapped inside these individual nanopores, in order to provide new insights about the growth mechanism involved in such systems. In particular, a coefficient of proportionality, C = 0.039 eV nm3, between the blue shift of the He K-edge and the He density has been found. In addition, very high He densities (10-100 at./nm3) and pressures in the gigapascal range (0.05-5.0 GPa) have been measured. The linear dependence of these parameters as a function of the inverse radii obeying to the Laplace-Young law for most of the pores suggests that their formation during the coating's growth takes place in regime of elastic deformation of the Co matrix. PMID- 29587248 TI - How do medical and nursing students experience emotional challenges during clinical placements? AB - Objectives: To investigate which kinds of situations medical and nursing students found emotionally challenging during their undergraduate education, and how they managed their experiences. Methods: This study used an exploratory research design. We gathered qualitative data using an open-ended questionnaire distributed to students in the middle and at the end of their education. In total, 49 nursing and 65 medical students participated. Also, five students were interviewed individually to acquire richer data. Data were analysed using narrative thematic analysis. Results: Medical and nursing students experienced a range of situations during their undergraduate education that they found emotionally challenging, mainly during clinical placements. The students' narratives concerned confronting patients' illness and death, unprofessional behaviour among healthcare professionals, dilemmas regarding patient treatment, students relating to patients as individuals and not diagnoses, and using patients for their own learning. The narratives concerned both the formal and the hidden curriculum, i.e., what is included in the profession (confronting illness and death), and what is not (unprofessional behaviour among healthcare professionals). Students managed their experiences by talking to trusted peers or supervisors, and by getting used to these situations. Conclusions: Despite the different knowledge, experiences, and conditions for medical and nursing students, our findings suggest that their experiences of emotional challenges are similar. Support and opportunities to talk about these experiences are important. Teachers, supervisors, and students need to be aware that students might experience emotionally difficult situations, and that the students need time for reflection and support. PMID- 29587249 TI - Activation of Adenylyl Cyclase Causes Stimulation of Adenosine Receptors. AB - BACKGROUND/AIMS: Signaling of Gs protein-coupled receptors (GsPCRs) is accomplished by stimulation of adenylyl cyclase, causing an increase of the intracellular cAMP concentration, activation of the intracellular cAMP effectors protein kinase A (PKA) and Epac, and an efflux of cAMP, the function of which is still unclear. METHODS: Activation of adenylyl cyclase by GsPCR agonists or cholera toxin was monitored by measurement of the intracellular cAMP concentration by ELISA, anti-phospho-PKA substrate motif phosphorylation by immunoblotting, and an Epac-FRET assay in the presence and absence of adenosine receptor antagonists or ecto-nucleotide phosphodiesterase/pyrophosphatase2 (eNPP2) inhibitors. The production of AMP from cAMP by recombinant eNPP2 was measured by HPLC. Extracellular adenosine was determined by LC-MS/MS, extracellular ATP by luciferase and LC-MS/MS. The expression of eNPP isoenzymes 1 3 was examined by RT-PCR. The expression of multidrug resistance protein 4 was suppressed by siRNA. RESULTS: Here we show that the activation of GsPCRs and the GsPCRs-independent activation of Gs proteins and adenylyl cyclase by cholera toxin induce stimulation of cell surface adenosine receptors (A2A or A2B adenosine receptors). In PC12 cells stimulation of adenylyl cyclase by GsPCR or cholera toxin caused activation of A2A adenosine receptors by an autocrine signaling pathway involving cAMP efflux through multidrug resistance protein 4 and hydrolysis of released cAMP to AMP by eNPP2. In contrast, in PC3 cells cholera toxin- and GsPCR-induced stimulation of adenylyl cyclase resulted in the activation of A2B adenosine receptors. CONCLUSION: Our findings show that stimulation of adenylyl cyclase causes a remarkable activation of cell surface adenosine receptors. PMID- 29587250 TI - Efficacy of Fine-Needle Aspiration Cytology in the Diagnosis of Tuberculous Cervical Lymphadenitis. AB - OBJECTIVE: This study assesses the role of fine-needle aspiration cytology (FNAC) in the diagnosis of tuberculous lymphadenitis (TL) in comparison with histology and bacteriology findings. STUDY DESIGN: We undertook a descriptive retrospective study of 937 FNAC specimens from 851 patients with cervical lymph nodes. The FNAC findings were then compared to histopathology and bacteriology. RESULTS: Of the 937 aspirates, the cytopathological diagnoses consisted of 426 (55.9%) TL, 185 (24.3%) reactive lymphoid hyperplasia, 18 (2.3%) suppurative inflammation, 78 (10.2%) malignant metastatic tumor, and 54 (7%) lymphoma. Of the 426 TL cases, 171 were diagnosed by FNAC combined with bacteriological examination. In this group, 22 cases were found to be positive on Ziehl-Neelsen stain and 16 by culture. A histopathology report was available for 62 cases. Compared to histopathology, the overall diagnostic sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of FNAC in the diagnosis of cervical TL were, respectively, 96.77, 100, 100, and 96.67%. When comparing bacteriology to histopathology, these values were 97.44, 100, 100, and 91.67%. CONCLUSION: Our study shows that FNAC is a sensitive and specific tool for the diagnosis of cervical TL. PMID- 29587251 TI - Pregnancy Outcomes in French Hemodialysis Patients. AB - BACKGROUND: Pregnancy in hemodialysis (HD) women is a rare event and often associated with maternal and fetal complications. Scarcity of available data from large cohorts impedes fair medical counseling. METHODS: This is a descriptive, retrospective, multi-centric study. Pregnant women on HD during the period from 1985 to 2015 in France were included. The primary outcome was a living infant discharged from hospital, while secondary outcomes included gestational age and birth weight. RESULTS: We identified 100 pregnancies in 84 women on HD, from 41 centers. Chronic HD was initiated during pregnancy for 17.7% (14/79) of patients explaining a 19.8% prevalence of catheter (19/96) and a preserved residual diuresis for 50% of pregnancy (43/86). Seventy-six (89.4%) women performed daily dialysis during the third trimester (6 times per week). Our primary outcome was met for 78% of newborns with a mean gestational age of 33.2 +/- 3.9 weeks and a mean birth weight of 1,719 +/- 730 g. CONCLUSIONS: Our study is one of the largest series of -pregnancies in HD patients. Despite recent progresses, these pregnancies remain at high risk, reinforcing the need for an early nephrologist obstetrician skilled team co-management. PMID- 29587252 TI - Fats in Foods: Current Evidence for Dietary Advice. AB - Current discussion of the importance of food fats in the risk of coronary heart disease (CHD) often suffers from preconceptions, misunderstandings, insufficient knowledge, and selective reasoning. As a result, the sustained controversy about dietary fat recommendations can be contradictory and confusing. To clarify some of these issues, the International Expert Movement to Improve Dietary Fat Quality in cooperation with the International Union of Nutritional Sciences (IUNS) organized a symposium at the 21st meeting of the IUNS, October 17, 2017, Buenos Aires, Argentina, to summarize the key scientific evidence underlying the controversy on the relationship between the saturated and unsaturated fat consumption and CHD risk. Presenters also discussed, using examples, the rationale for and implications of the partial replacement of foods rich in saturated fats by those rich in unsaturated fats. Presentations included strategies to fit healthier fats into meals. This report summarizes the symposium presentations. PMID- 29587253 TI - Early and One-Year Outcomes of Acute Stroke in the Industrial Region of Poland During the Decade 2006-2015: The Silesian Stroke Registry. AB - BACKGROUND: Poland, classified as a high-income country, is still considered to have a high cardiovascular risk population. During the last decade, the standards of care in acute stroke (AS) had markedly improved; thus, we aimed to assess whether and how it translated into early and late outcomes. METHODS: Silesian Stroke Registry was created from the administrative database of the public, obligatory, health -insurer in Poland. The AS cases were selected based on primary diagnosis coded in ICD-10 as I60-I64 for years 2006-2015 (n = 120,844). Index hospitalization together with data on re-hospitalizations, procedures, ambulatory visits, rehabilitation and all-cause deaths in a 1-year follow-up were analyzed. RESULTS: The rates of admissions per 100,000 adult population varied between 41-47 for haemorrhagic and 257-275 for ischaemic stroke with substantial decrease in almost all age groups except for the oldest patients. In ischaemic stroke, thrombolytic therapy raised from 0 to 8.8% in 2015, along with significant trends of decreasing 30-day (from 20 to 16%) and 12-month (from 35 to 31%) case fatality. In haemorrhagic stroke, case fatality had not changed. After ischaemic stroke, 12-month readmissions due to AS declined from 11-12% in 2006 2009 to 9% in 2010-2014. The percentage of patients benefiting from rehabilitation increased from 24 to 32%. CONCLUSIONS: In a large population of industrial province, we showed recent, positive trends in AS admissions, treatment and 1-year outcomes. Development of stroke unit networks and increase in thrombolytic treatment were at least in part responsible for survival improvement and reduction of recurrence of AS. However, case-fatality and stroke recurrence remain high compared to those of other developed countries. PMID- 29587254 TI - Evaluation of the FreeStyle(r) Libre Flash Glucose Monitoring System in Children and Adolescents with Type 1 Diabetes. AB - BACKGROUND/AIMS: The FreeStyle(r) Libre Flash Glucose Monitoring System (FGM, Abbott) measures glucose concentrations in the interstitial fluid for up to 14 days. It has been approved for use in children aged > 4 years in January 2016. Experience in children is still limited. We evaluated the accuracy and usability of the FGM in children with type 1 diabetes mellitus (DM). METHODS: 67 children with type 1 DM (35 girls), aged 4-18 years, were included. Subjects wore a sensor on the back of their upper arm. For the first 14 days, they regularly measured capillary blood glucose (BG) with their usual BG meter (Accu-Chek(r) Mobile [ACM], Roche [n = 24]; Contour(r) Next Link [CNL], Bayer [n = 26]; OneTouch(r) Verio(r) IQ [OTV], LifeScan [n = 17]) followed by a sensor glucose (SG) scanning. SG readings were compared to BG measurements by consensus error grid (CEG) analysis; the mean difference (MD), the mean relative difference (MRD), the mean absolute difference (MAD), and the mean absolute relative difference (MARD) were calculated. After 14 days, subjects were asked to fill in a questionnaire on the usability of the FGM. RESULTS: 2,626 SG readings were paired with BG results. FGM readings were highly correlated with BG (r = 0.926, p < 0.001). 80.3% of the data pairs were in zone A (= no effect on clinical action) and 18.4% were in zone B (= altered clinical action with little or no effect on the clinical outcome) of the CEG. Overall MD was +7.5 mg/dL; MD varied with the BG meter: ACM +10.4 mg/dL, CNL +14.2 mg/dL, OTV -3.6 mg/dL (p < 0.001). Overall, MARD was 16.7%. We observed a large interindividual variability in the accuracy parameters. MD and MRD were inversely related to BMI (r = -0.261 [p < 0.05]; r = -0.266 [p < 0.05], respectively). MARD was inversely related to age (r = -0.266 [p < 0.05]). Twenty nine patients (43.3%) reported sensor problems, mainly early detachment of the sensor. Nonetheless, the usability questionnaire indicated high levels of satisfaction. CONCLUSIONS: Our results showed a reasonable agreement between the FGM SG readings and capillary BG measurements in children. There was, however, a large interindividual variability. The wearing of the sensor requires special attention. Further studies in children are imperative in order to document the accuracy and safety of the FGM in the paediatric population. PMID- 29587255 TI - Behaviour and Ecology of Male Aye-Ayes (Daubentonia madagascariensis) in the Kianjavato Classified Forest, South-Eastern Madagascar. AB - Previous studies found that aye-ayes (Daubentonia madagascariensis) consume a variety of non-invertebrate resources, supporting the hypothesis that aye-ayes are too large-bodied to focus feeding efforts on insects. However, these conclusions were based on introduced populations, with little known about aye-aye behaviour and ecology in its natural habitat. This study investigates activity budgets, diet, and home range/territories of 2 male aye-ayes in the Kianjavato Classified Forest, a disturbed forest in south-eastern Madagascar, from October 2013 to October 2014. We used radiotelemetry and focal-animal sampling methods to collect behavioural data. We recorded GPS coordinates of the focal animal every 20 min, calculating the home range size for each individual. Results showed that male aye-ayes spent most of their time feeding and travelling. Their feeding time primarily focussed on larvae and adult insects from various substrates, and to a lesser extent Canarium spp. seeds. Home range sizes of the 2 males varied between individuals, overlapped greatly, and appeared to be related to the location of females. Our findings indicate that aye-aye behaviours are strongly indicative of insect-centric feeding ecology. PMID- 29587256 TI - Protein Biomarkers in Asthma. AB - Asthma is a chronic disabling respiratory disease that can be triggered by a variety of factors, including allergens, respiratory infections, psychological factors, occupational agents, exercise, atmospheric pollutants, and drugs. The asthma syndrome has been treated for decades according to a "one-fits-all" treatment strategy based on bronchodilators and steroids. With the availability of new forms of treatment targeting the different pathomechanisms of the asthma syndrome, such as anti-immunoglobulin E and cytokine-targeting therapies, the interest in biomarkers that can dis criminate different forms of asthma according to their pathomechanisms has increased. This review attempts to provide an overview of protein biomarkers in asthma and how they might be used to discriminate different forms of asthma that may respond positively to sophisticated new targeted therapies. PMID- 29587257 TI - A Network-Wide Stroke Team Program Reduces Time to Treatment for Endovascular Stroke Therapy in a Regional Stroke-Network. AB - BACKGROUND AND PURPOSE: Driven by the positive results of randomized, controlled trials of endovascular stroke therapies (EVT) in stroke patients with large vessel occlusion, different approaches to speed up the workflow for EVT candidates are currently being implemented worldwide. We aimed to assess the effect of a simple stroke network-wide workflow improvement project, primarily focusing on i.v. thrombolysis, on process times for patients undergoing EVT. METHODS: In 2015, we conducted a network-wide, peer-to-peer acute stroke workflow improvement program for i.v. thrombolysis with the main components of implementing a binding team-based algorithm at every stroke unit of the regional network, educating all stroke teams about non-technical skills and providing a stroke-specific simulation training. Before and after the intervention we recorded periprocedural process times, including patients undergoing EVT at the 3 EVT-capable centers (January - June 2015, n = 80 vs. July 2015 - June 2016, n = 184). RESULTS: In this multi-centric evaluation of 268 patients receiving EVT, we observed a relevant shortening of the median time from symptom onset to EVT specifically in patients requiring secondary transfer by almost an hour (300 min, 25-75% interquartile range [IQR] 231-381 min to 254 min, IQR 215.25-341 min; p = 0.117), including a reduction of the median door-to-groin time at the EVT-capable center in this patient group by 15.5 min (59 min, IQR 35-102 min to 43.5 min, IQR 27.75-81.25 min; p = 0.063). In patients directly admitted to an EVT-capable center, the median door-to-groin interval was reduced by 10.5 min (125 min, IQR 83.5-170.5 min to 114.5 min, IQR 66.5-151 min; p = 0.167), but a considerable heterogeneity between the centers was observed (p < 0.001). CONCLUSIONS: We show that a simple network-wide workflow improvement program primarily directed at fast i.v. thrombolysis also accelerates process times for EVT candidates and is a promising measure to improve the performance of an entire stroke network. PMID- 29587258 TI - Sulodexide Slows Down the Senescence of Aortic Endothelial Cells Exposed to Serum from Patients with Peripheral Artery Diseases. AB - BACKGROUND/AIMS: Aging of the arterial endothelial cells results in the appearance of their inflammatory phenotype, which may predispose patients to the acceleration of arteriosclerosis. We studied the effect of serum from patients with peripheral artery disease (PAD) on the senescence of human aortic endothelial cells (HAEC) and how that process is modulated by sulodexide. METHODS: HAEC replicative aging in vitro was studied in the presence of 10% PAD serum (PAD Group) or10%PAD serum and Sulodexide 0.5 LRU/mL (PAD-SUL group). In control group cells were cultured in medium supplemented with 10% fetal bovine serum. All studied parameters were evaluated at the beginning and at the end of the study, in all experimental groups. Population doubling time (PDT) was studied from the cells growth rate after repeated passages, and senescence-associated beta- galactosidase activity (SA-beta gal activity) was measured with the fluorescence flow cytometry. Expression of IL6, vWF, p21 and p53 genes was measured with the real-time polymerase chain reaction (Real-Time PCR). Concentrations of IL6 and vWF were measured with the standard ELISA kits. RESULTS: PAD serum accelerated the senescence of HAEC as reflected by increased, compared to control, expression of the IL6 gene (+43%, p<0.05) vWF gene (+443%, p<0.01), p21 gene (+ 124%, p<0.01) and p53 gene (+ 85%, p<0.01). Secretion of IL6 and vWF was higher in that group: + 101%, p<0.01 and + 78%, p<0.01, respectively, as compared to control. Also, SA-beta gal activity was higher in the PAD group (+33%, p<0.05) than in the control group. In the PAD group PDT was longer (+108%, p<0.01) as compared to control. Simultaneous use of Sulodexide with PAD serum significantly reduced all the above described senescent changes in HAEC. CONCLUSIONS: PAD serum accelerates the aging of HAEC which may result in the faster progression of arteriosclerosis. Sulodexide reduces PAD induced senescence of HAEC, which results in lower inflammatory and thrombogenic activity of these cells. PMID- 29587259 TI - Kruppel-Like Factor 4 Inhibits Pancreatic Cancer Epithelial-to-Mesenchymal Transition and Metastasis by Down-Regulating Caveolin-1 Expression. AB - BACKGROUND/AIMS: Kruppel-like factor 4 (KLF4), a member of the KLF family of zinc finger transcription factors, has been identified as a tumor suppressor gene in a variety of tumors. However, the molecular mechanisms by which KLF4 inhibits epithelial-to-mesenchymal transition (EMT) and metastasis in pancreatic cancer remain unclear. METHODS: KLF4 expression in pancreatic cancer was analyzed using public datasets (Oncomine and The Cancer Genome Atlas). The expression of KLF4, caveolin-1 (Cav-1), E-cadherin, and vimentin, and their correlations with clinicopathological characteristics were evaluated by immunohistochemistry in pancreatic cancer tissues. The biological functions and underlying mechanisms of KLF4 expression on EMT and metastasis were also investigated in vitro and in vivo. RESULTS: Public datasets showed that KLF4 expression was significantly decreased in pancreatic cancer and correlated with the depth of invasion and disease stage. The expression of KLF4, Cav-1, E-cadherin, and vimentin protein in pancreatic cancer tissues was closely associated with pathological grade, disease stage, and metastasis. KLF4 expression was also positively correlated with E cadherin expression and negatively correlated with vimentin expression, whereas Cav-1 expression was negatively associated with E-cadherin expression and positively correlated with vimentin expression. Knockdown of KLF4 expression promoted EMT and facilitated pancreatic cancer cell growth and metastasis in vitro and in vivo. In addition, immunohistochemistry (IHC) results indicated that KLF4 expression was negatively correlated with Cav-1 expression. Furthermore, down-regulating KLF4 expression increased Cav-1 and vimentin expression and decreased E-cadherin expression. Mechanistically, KLF4 could transcriptionally inhibit Cav-1 expression by binding directly to the promoter domain of Cav-1. CONCLUSIONS: KLF4 inhibits pancreatic cancer EMT and metastasis by down regulating Cav-1 expression, suggesting that the KLF4/Cav-1 signaling pathway may be a novel diagnostic and therapeutic target. PMID- 29587260 TI - Verbascoside Alleviates Atopic Dermatitis-Like Symptoms in Mice via Its Potent Anti-Inflammatory Effect. AB - BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by the interplay between multiple genetic and environmental factors. The pathogenesis of AD remains incompletely understood. Treatment with topical steroids for chronic AD symptoms has severe side effects and so a new treatment is required. Verbascoside is a hydrophilic phenylethanoid glycoside with antioxidant, anti-inflammatory properties. METHODS: Verbascoside was evaluated in AD-like lesions induced by the repetitive and alternative application of 2,4-dinitrochlorobenzene (DNCB) in BALB/c mice. Overall symptomatic score and serological and molecular changes of the skin lesions were investigated. RESULTS: Verbascoside relieved the overall AD-like symptoms such as scratching behavior and skin lesion severity. At whole-body level, verbascoside significantly reduced DNCB-induced IgE and Th2 cytokines in the peripheral blood. At the skin lesion site, verbascoside also inhibited DNCB-induced production of proinflammatory cytokine TNF-alpha, IL-6, and IL-4 mRNA. In a human monocyte THP 1 model, verbascoside could suppress DNCB-induced upregulation of CD86 and CD54 at the cell surface, the secretion of the proinflammatory cytokines TNF-alpha and IL-6, and the activation of NFkappaB signaling in a dose-dependent manner. CONCLUSION: Our results demonstrate that verbascoside could be a potential therapeutic agent for the treatment of AD. PMID- 29587261 TI - High Frequency of Copy-Neutral Loss of Heterozygosity in Patients with Myelofibrosis. AB - Myelofibrosis is the rarest and most severe type of Philadelphia-negative classical myeloproliferative neoplasms. Although mutually exclusive driver mutations in JAK2, MPL, or CALR that activate JAK-STAT pathway have been related to the pathogenesis of the disease, chromosome abnormalities have also been associated with the phenotype and prognosis of the disease. Here, we report the use of a chromosomal microarray platform consisting of both oligo and SNP probes to improve the detection of chromosome abnormalities in patients with myelofibrosis. Sixteen patients with myelofibrosis were tested, and the results were compared to karyotype analysis. Driver mutations in JAK2, MPL, or CALR were investigated by PCR and MLPA. Conventional cytogenetics revealed chromosome abnormalities in 3 out of 16 cases (18.7%), while chromosomal microarray analysis detected copy-number variations (CNV) or copy-neutral loss of heterozygosity (CN LOH) alterations in 11 out of 16 (68.7%) patients. These included 43 CN-LOH, 14 deletions, 1 trisomy, and 1 duplication. Ten patients showed multiple chromosomal abnormalities, varying from 2 to 13 CNVs or CN-LOHs. Mutational status for JAK2, CALR, and MPL by MLPA revealed a total of 3/16 (18.7%) patients positive for the JAK2 V617F mutation, 9 with CALR deletion or insertion and 1 positive for MPL mutation. Considering that most of the CNVs identified were smaller than the karyotype resolution and the high frequency of CN-LOHs in our study, we propose that chromosomal microarray platforms that combine oligos and SNP should be used as a first-tier genetic test in patients with myelofibrosis. PMID- 29587262 TI - Whole-Genome Linkage Analysis with Whole-Exome Sequencing Identifies a Novel Frameshift Variant in NEFH in a Chinese Family with Charcot-Marie-Tooth 2: A Novel Variant in NEFH for Charcot-Marie-Tooth 2. AB - BACKGROUND: Charcot-Marie-Tooth disease (CMT) is the most common neurodegenerative disorder of the peripheral nervous system. More than 50 genes/loci were found associated with the disease. We found a family with autosomal-dominant CMT2. OBJECTIVE: To reveal the pathogenic gene of the family and further investigate the function of the variant. METHODS: DNA underwent whole genome linkage analysis for all family members and whole-exome sequencing for 2 affected members. Neurofilament light polypeptide and wild-type or mutant neurofilament heavy polypeptide (NEFH) were co-transfected into SW13 (vim-) cells. The nefh-knockdown zebrafish model was produced by using morpholino antisense oligonucleotides. RESULTS: We identified a novel insertion variant (c.3057insG) in NEFH in the family. The variant led to the loss of a stop codon and an extended 41 amino acids in the protein. Immunofluorescence results revealed that mutant NEFH disrupted the neurofilament network and induced aggregation of NEFH protein. Knockdown of nefh in zebrafish caused a slightly or severely curled tail. The motor ability of nefh-knockdown embryos was impaired or even absent, and the embryos showed developmental defects of axons in motor neurons. The abnormal phenotype and axonal developmental defects could be rescued by injection of human wild-type but not human mutant NEFH mRNA. CONCLUSIONS: We identified a novel stop loss variant in NEFH that is likely pathogenic for CMT2, and the results provide further evidence for the role of an aberrant assembly of neurofilament in CMT. PMID- 29587263 TI - A Real-Life Multicenter National Study on Nintedanib in Severe Idiopathic Pulmonary Fibrosis. AB - BACKGROUND: Two therapeutic options are currently available for patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF): pirfenidone and nintedanib. To date, there is still insufficient data on the efficacy of these 2 agents in patients with more severe disease. OBJECTIVES: This national, multicenter, retrospective real-life study was intended to determine the impact of nintedanib on the treatment of patients with severe IPF. METHODS: All patients included had severe IPF and had to have at least 6 months of follow-up before and at least 6 months of follow-up after starting nintedanib. The aim of the study was to compare the decline in lung function before and after treatment. Patient survival after 6 months of therapy with nintedanib was assessed. RESULTS: Forty-one patients with a forced vital capacity (FVC) <=50% and/or a diffusing capacity of the lung for carbon monoxide (DLCO) <=35% predicted at the start of nintedanib treatment were enrolled. At the 6-month follow-up, the decline of DLCO (both absolute and % predicted) was significantly reduced compared to the pretreatment period (absolute DLCO at the -6-month, T0, and +6-month time points (5.48, 4.50, and 5.03 mmol/min/kPa, respectively, p = 0.03; DLCO% predicted was 32.73, 26.54, and 29.23%, respectively, p = 0.04). No significant beneficial effect was observed in the other functional parameters analyzed. The 1-year survival in this population was 79%, calculated from month 6 of therapy with nintedanib. CONCLUSIONS: This nationwide multicenter experience in patients with severe IPF shows that nintedanib slows down the rate of decline of absolute and % predicted DLCO but does not have significant impact on FVC or other lung parameters. PMID- 29587264 TI - Different Adaptive Responses to Hypoxia in Normal and Multiple Myeloma Endothelial Cells. AB - BACKGROUND/AIMS: Hypoxia is a powerful stimulator of angiogenesis under physiological as well as pathological conditions. Normal endothelial cells (EC), such as human umbilical vein EC (HUVEC), are relatively affected by hypoxic insult in terms of cell survival. In contrast, EC from tumors are particularly resistant to hypoxia-induced cell death. Previous reports have shown that EC in bone marrow from multiple myeloma (MM) patients had a hypoxic phenotype, even under normoxic conditions. The aim of this study was to evaluate whether HUVEC and MMEC adapt differently to hypoxia. METHODS: Cell proliferation was assessed by the CyQUANT assay. Cdc25A, p21, Bax, Bcl-xl, BNIP3, glucose transporter (GLUT) 1, monocarboxylate transporter (MCT)-4 and carbonic anhydrase (CA)IX mRNA expression was determined by qRT-PCR. HIF-1alpha, BNIP3, Beclin-1, LC3B, livin, Bax, Bcl-xl, p21, p62 and beta-actin protein expression was analyzed by western blot. Apoptosis was determined by TUNEL assay. Silencing of BNIP3 was achieved by stealth RNA system technology. RESULTS: While HUVEC survival was reduced after prolonged hypoxic exposure, MMEC were completely unaffected. This difference was also significant in terms of livin, cdc25A and p21 expression. Hypoxia induced apoptosis and inhibited autophagy in HUVEC, but not in MMEC, where hypoxic treatment resulted in a more sustained adaptive response. In fact, MMEC showed a more significant increase in the expression of genes regulated transcriptionally by hypoxia-inducible factor (HIF)-1alpha. Interestingly, they showed higher expression of BNIP3 than did HUVEC, indicating a more pronounced autophagic (and pro-survival) phenotype. The potential role of BNIP3 in EC survival was confirmed by BNIP3 siRNA experiments in HUVEC, where BNIP3 inhibition resulted in reduced cell survival and increased apoptosis. CONCLUSION: These findings provide further information on how hypoxia may affect EC survival and could be important for a better understanding of EC physiology under normal and pathological conditions, such as in multiple myeloma. PMID- 29587265 TI - Transforming Growth Factor Beta 1 Drives a Switch in Connexin Mediated Cell-to Cell Communication in Tubular Cells of the Diabetic Kidney. AB - BACKGROUND/AIMS: Changes in cell-to-cell communication have been linked to several secondary complications of diabetes, but the mechanism by which connexins affect disease progression in the kidney is poorly understood. This study examines a role for glucose-evoked changes in the beta1 isoform of transforming growth factor (TGFbeta1), on connexin expression, gap-junction mediated intercellular communication (GJIC) and hemi-channel ATP release from tubular epithelial cells of the proximal renal nephron. METHODS: Biopsy material from patients with and without diabetic nephropathy was stained for connexin-26 (CX26) and connexin-43 (CX43). Changes in expression were corroborated by immunoblot analysis in human primary proximal tubule epithelial cells (hPTECs) and model epithelial cells from human renal proximal tubules (HK2) cultured in either low glucose (5mmol/L) +/- TGFbeta1 (2-10ng/ml) or high glucose (25mmol/L) for 48h or 7days. Secretion of the cytokine was determined by ELISA. Paired whole cell patch clamp recordings were used to measure junctional conductance in control versus TGFbeta1 treated (10ng/ml) HK2 cells, with carboxyfluorescein uptake and ATP biosensing assessing hemi-channel function. A downstream role for ATP in mediating the effects of TGF-beta1 on connexin mediated cell communication was assessed by incubating cells with ATPgammaS (1-100uM) or TGF-beta1 +/- apyrase (5 Units/ml). Implications of ATP release were measured through immunoblot analysis of interleukin 6 (IL-6) and fibronectin expression. RESULTS: Biopsy material from patients with diabetic nephropathy exhibited increased tubular expression of CX26 and CX43 (P<0.01, n=10), data corroborated in HK2 and hPTEC cells cultured in TGFbeta1 (10ng/ml) for 7days (P<0.001, n=3). High glucose significantly increased TGFbeta1 secretion from tubular epithelial cells (P<0.001, n=3). The cytokine (10ng/ml) reduced junctional conductance between HK2 cells from 4.5+/-1.3nS in control to 1.15+/-0.9nS following 48h TGFbeta1 and to 0.42+/-0.2nS after 7days TGFbeta1 incubation (P<0.05, n=5). Acute (48h) and chronic (7day) challenge with TGFbeta1 produced a carbenoxolone (200uM)-sensitive increase in carboxyfluorescein loading, matched by an increase in ATP release from 0.29+/ 0.06MUM in control to 1.99+/-0.47MUM after 48hr incubation with TGFbeta1 (10ng/ml; P<0.05, n=3). TGF-beta1 (2-10ng/ml) and ATPgammas (1-100uM) increased expression of IL-6 (P<0.001 n=3) and fibronectin (P<0.01 n=3). The effect of TGF beta1 on IL-6 and fibronectin expression was partially blunted when preincubated with apyrase (n=3). CONCLUSION: These data suggest that chronic exposure to glucose-evoked TGFbeta1 induce an increase in CX26 and CX43 expression, consistent with changes observed in tubular epithelia from patients with diabetic nephropathy. Despite increased connexin expression, direct GJIC communication decreases, whilst hemichannel expression/function and paracrine release of ATP increases, changes that trigger increased levels of expression of interleukin 6 and fibronectin. Linked to inflammation and fibrosis, local increases in purinergic signals may exacerbate disease progression and highlight connexin mediated cell communication as a future therapeutic target for diabetic nephropathy. PMID- 29587266 TI - Overexpression of PTPN2 in Visceral Adipose Tissue Ameliorated Atherosclerosis via T Cells Polarization Shift in Diabetic Apoe-/- Mice. AB - BACKGROUND/AIMS: Dysregulated inflammation in adipose tissue, marked by increased pro-inflammatory T-cell accumulation and reduced regulatory T cells (Treg), contributes to diabetes-associated insulin resistance and atherosclerosis. However, the molecular mechanisms underlying T-cell-mediated inflammation in adipose tissue remain largely unknown. METHODS: Sixty apolipoprotein E (ApoE-/-) mice were randomly divided into chow and diabetes groups. Diabetes was induced by a high-fat and high-sugar diet combined with low-dose streptozotocin. Then we transferred a recombinant adenovirus carrying the protein tyrosine phosphatase non-receptor type 2 (PTPN2) gene into epididymal white adipose tissue (EWAT) of ApoE-/- mice. After transfection, all mice were euthanized to evaluate the effects of PTPN2 on T cells polarization and atherosclerosis. RESULTS: PTPN2 was downregulated in EWAT of diabetic ApoE-/- mice. PTPN2 overexpression in EWAT reversed the high Th1/Treg and Th17/Treg ratios in EWAT of diabetic mice. In addition, PTPN2 overexpression in EWAT could significantly reduce macrophages infiltration, the ratio of M1/M2 macrophages and the expression of pro inflammatory cytokines in EWAT, improving insulin resistance. In aortic root lesions, the vulnerability index were significantly decreased by overexpression of PTPN2 in EWAT. CONCLUSION: These data suggested that PTPN2 overexpression in EWAT would inhibit systemic inflammation and increase the plaque stability via T cells polarization shift in diabetic mice. PMID- 29587267 TI - Distance from Home to Research Center: A Barrier to In-Person Visits but Not Treatment Adherence in a Stroke Trial. AB - BACKGROUND AND PURPOSE: Clinical trials often seek to enroll patients from both urban and rural areas to safeguard the generalizability of results. However, maintaining contact with patients who live away from a recruitment site, including rural areas, can be challenging. In this research we examine the effect of distance between patient and study centers on treatment adherence and retention. METHODS: Secondary analysis of 2,466 participants in the Insulin Resistance Intervention after Stroke trial who were enrolled from research sites in the United States. Driving distance between the zipcodes of patient's reported place of residence and the study center was calculated. Outcome measures were loss to follow-up, completion of annual in-person visits, adherence to preventive therapy, and adherence to study drug in the first 3 years of participation. Logistic regression models were used to adjust for confounders. RESULTS: Distance from residence to research center was not associated with loss to follow-up, adherence to study drug, or adherence to preventive therapy (p > 0.05 for each). However, patients who lived farther from the research center (>120 miles), compared to patients who lived closer (<60 miles), were less likely to complete the second annual in-person visit (62 vs. 81%; adjusted OR 0.48; 95% CI 0.31 0.75) and third visit (53 vs. 75%; adjusted OR 0.44; 95% CI 0.29-0.67). CONCLUSIONS: Distance between patient and study center was an independent predictor of missed in-person visits but not with adherence to study treatment or preventive care. PMID- 29587268 TI - MicroRNA-30a Suppresses the Activation of Hepatic Stellate Cells by Inhibiting Epithelial-to-Mesenchymal Transition. AB - BACKGROUND/AIMS: The activation of hepatic stellate cells (HSCs) is considered as a pivotal event in liver fibrosis and epithelial-mesenchymal transition (EMT) process has been reported to be involved in HSC activation. It is known that microRNAs (miRNAs) play a pro-fibrotic or anti-fibrotic role in HSC activation. Recently, emerging studies show that miR-30a is down-regulated in human cancers and over-expression of miR-30a inhibits tumor growth and invasion via suppressing EMT process. However, whether miR-30a could regulate EMT process in HSC activation is still unclear. METHODS: miR-30a expression was quantified using real-time PCR in carbon tetrachloride (CCl4)-induced rat liver fibrosis, activated HSCs and patients with cirrhosis. Roles of miR-30a in liver fibrosis in vivo and in vitro were also analyzed. Luciferase activity assays were performed to examine the binding of miR-30a to the 3'-untranslated region of snail family transcriptional repressor 1 (Snai1). RESULTS: miR-30a was down-regulated in human cirrhotic tissues. In CCl4 rats, reduced miR-30a was found in fibrotic liver tissues as well as isolated HSCs. There was a significant reduction in miR-30a in primary HSCs during culture days. miR-30a over-expression resulted in the suppression of CCl4-induced liver fibrosis. Restoration of miR-30a led to the inhibition of HSC activation including cell proliferation, alpha-SMA and collagen expression. Notably, miR-30a inhibited EMT process, with a reduction in TGF-beta1 and Vimentin as well as an increase in GFAP and E-cadherin. miR-30a induced a significant reduction in Snai1 protein expression when compared with the control. Interestingly, Snail protein expression was increased during liver fibrosis, indicating that there may be a negative correlation between miR-30a level and Snai1 protein expression. Further studies demonstrated that Snai1 was a target of miR-30a. CONCLUSION: Our results suggest that miR-30a inhibits EMT process, at least in part, via reduction of Snai1, leading to the suppression of HSC activation in liver fibrosis.

PMID- 29587269 TI - Functions of the Signal Transducer and Activator of Transcription 6 in a Behavioral Animal Model of Depression. AB - AIMS: Depression is one of the most common inflammatory and mental disorders. Signal transducer and activator of transcription 6 (STAT6) plays a crucial role in the pathology of mental disorders as well as inflammatory diseases. METHODS: Here we determined the role of STAT6 in the pathogenesis of depression using STAT6-deficient mice in a forced swimming test. RESULTS: The immobility time was significantly decreased in STAT6-deficient mice compared to wild-type mice without alteration of locomotor activity. STAT6-deficient mice exhibited a significantly enhancing dopamine and 5-hydroxytryptamine (5-HT, serotonin) in brain. In addition, the expression of serotonin transporter in the hippocampus was markedly downregulated in STAT6-deficient mice. These results provide the first evidence that STAT6 affects depressive-like behavior through downregulating monoamines, including dopamine and 5-HT in the hippocampus of brain. CONCLUSIONS: In conclusion, identification of STAT6 signaling pathways on depression might open new perspectives for antidepressant therapies. PMID- 29587271 TI - Iterative Variance Stabilizing Transformation Denoising of Spectral Domain Optical Coherence Tomography Images Applied to Retinoblastoma. AB - BACKGROUND: Due to the presence of speckle Poisson noise, the interpretation of spectral domain-optical coherence tomography (SD-OCT) images frequently requires the use of data averaging to improve the signal-to-noise ratio. This implies long acquisition times and requires patient sedation in some cases. Iterative variance stabilizing transformation (VST) is a possible approach by which to remove speckle Poisson noise on single images. METHODS: We used SD-OCT images of human and murine (LH Beta-Tag mouse model) retinas with and without retinoblastoma acquired with 2 different imaging devices (Bioptigen and Micron IV). These images were processed using a denoising workflow implemented in Matlab. RESULTS: We demonstrated the presence of speckle Poisson noise, which can be removed by a VST based approach. This approach is robust as it works in all used imaging devices and in both human and mouse retinas, independently of the tumor status. The implemented algorithm is freely available from the authors on demand. CONCLUSIONS: On a single denoised image, the proposed method provides results similar to those expected from the SD-OCT averaging. Because of the friendly user interface, it can be easily used by clinicians and researchers in ophthalmology. PMID- 29587272 TI - Development of an Immunoassay for Detection of Torque Teno Virus (TTV) Antibodies Using the N22 Expression Product from TTV Genotype 2. AB - AIMS: This study describes an immunoassay to detect anti-torque teno virus (TTV) antibodies using a peptide obtained from expression of the N22 region of TTV genotype 2. METHODS: The N22 region (~500 bp) of TTV genotype 2 was cloned in a pET-28a(+) vector and expressed in ZYM-5052 autoinduction medium. Following metal affinity chromatography, a purified polypeptide was used as an antigen for the development of an immunoassay to detect anti-TTV antibodies in human sera. RESULTS: Recombinant protein (~25-kDa) was obtained after 24 h of incubation at 25 degrees C in ZYM-5052 autoinduction medium. A blot assay developed using this polypeptide as an antigen and TTV-positive sera as the primary antibody produced a distinct spot on the nitrocellulose membrane. Serum samples from 36 of 42 patients with renal disease and 29 of 48 patients with liver diseases produced a positive signal using this immunoassay. Simultaneously, 18 of 48 healthy controls were also detected to be positive for anti-TTV antibodies. These results were found to be comparable with TTV detection using PCR, and the assay showed a high sensitivity and specificity (i.e., 97.44 and 91.67%, respectively). Moreover, this assay could detect TTV infection irrespectively of the genotype, including cases of mixed infection. CONCLUSION: The present immunoassay using the N22 expression product may be used as an alternative to PCR to detect TTV infection in large populations. PMID- 29587273 TI - Neutrophil-to-Lymphocyte Ratio and Platelet Count Predict Long-Term Outcome of Stage IIIC Epithelial Ovarian Cancer. AB - BACKGROUND/AIMS: Prognostic value of neutrophil-to-lymphocyte ratio (NLR) and platelet count (PC) in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC epithelial ovarian cancer (EOC) is controversial. METHODS: A total of 370 stage IIIC EOC patients who underwent primary debulking surgery (PDS) at the Department of Gynecology of Liaoning Cancer Hospital and Institute between January 2003 and August 2016 and had full information were involved. Patients were stratified into a high NLR (H-NLR) group versus a low NLR (L-NLR) group and a high PC (H-PC) group versus a low PC (L-PC) group according to cutoff values calculated through receiver operating characteristic (ROC) curves. Prognostic values of NLR and PC for progression-free survival (PFS) and overall survival (OS) were assessed. RESULTS: We identified the optimal cut-off value of 3.08 for NLR and 289.5*109/L for PC. The median PFS and OS of the patients with H-NLR were shorter than L-NLR (PFS: 16.9 months vs. 19.5 months, hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.03-1.63, P = 0.022; OS: 33.5 months vs. 46.8 months, HR 1.3, 95% CI 1.01-1.66, P = 0.001). The median PFS and OS of the patients with H-PC were shorter than L-PC (PFS: 15.3 months vs. 21.6 months, HR 1.3, 95% CI 1.04-1.63, P < 0.001; OS: 37.3 months vs. 46.1 months, HR 1.14, 95% CI 0.89-1.46, P = 0.306). CONCLUSIONS: H-NLR and H-PC could predict poor long-term outcome of patients with FIGO stage III EOC. PMID- 29587274 TI - Bajijiasu Ameliorates beta-Amyloid-Triggered Endoplasmic Reticulum Stress and Related Pathologies in an Alzheimer's Disease Model. AB - BACKGROUND/AIMS: Alzheimer disease (AD) is a common neurodegenerative disease that is characterized by the deposition of beta-amyloid peptide and formation of intracellular neurofibrillary tangles. Due to the failure of various clinical trials of novel drugs for AD, effective drugs for AD treatment are urgently required. METHODS: In this study, we used the classic APP/PS1 mouse model to explore the neuroprotective effects of a new compound, bajijiasu, and the mechanisms involved. Behavioral tests and western blotting were performed to assess the beneficial effects of bajijiasu in APP/PS1 mice. RESULTS: Morris water maze and Y-maze test results showed that oral administration of bajijiasu (35 mg/kg/day and 70 mg/kg/day) improved learning and memory abilities in APP/PS1 mice. Bajijiasu reduced ROS and MDA levels in both the hippocampus and cortex. Moreover, western blotting results showed that bajijiasu protected neurons from apoptosis, elevated the expression levels of neurotrophic factors, and alleviated endoplasmic reticulum stress in both the hippocampus and cortex. CONCLUSION: These results indicate that the mechanisms underlying the effects of bajijiasu on AD might be related to beta-amyloid-downstream pathologies, particularly endoplasmic reticulum stress. PMID- 29587275 TI - Efficacy Analysis of Capsaicin 8% Patch in Neuropathic Peripheral Pain Treatment. AB - BACKGROUND/AIMS: Several guidelines for neuropathic pain management and various effective drugs are available; however, neuropathic pain remains undertreated. This retrospective study aimed to evaluate the efficacy of topical capsaicin 8% in peripheral neuropathic pain in a routine clinical setting. METHODS: Therapeutic efficacy was evaluated through pain intensity, using numerical pain rating scale at baseline and 7-14 days after each treatment, and using pain treatment area (PTA) assessed immediately before each treatment. RESULTS: A total of 43 patients with either post-herpetic neuralgia or post-traumatic/post surgical neuropathic pain were enrolled. The median percentage reduction in numerical pain rating scale score and in PTA was -40.0 (-50.0 to -33.3; 95% CI, bootstrap) and -35.1 (-50.9 to 3.4; 95% CI, bootstrap), respectively. Pain intensity and PTA were equally improved and reduced in both treated conditions. CONCLUSION: This study suggests that topical capsaicin 8% reduces peripheral neuropathic pain as well as treatment pain area. PMID- 29587276 TI - Improving Bone Regeneration Using Chordin siRNA Delivered by pH-Responsive and Non-Toxic Polyspermine Imidazole-4,5-Imine. AB - BACKGROUND/AIMS: Bone nonunion remains a challenge for orthopaedists. The technological advancements that have been made in precisely silencing target genes have provided promising methods to address this challenge. METHODS: We detected the expression levels of the bone morphogenetic protein (BMP) inhibitors Chordin, Gremlin and Noggin using realtime PCR in bone mesenchymal stem cells (BMSCs) isolated from patients with normal fracture healing and those with bone nonunion. Moreover, we detected the expression of Chordin, Gremlin and Noggin during the osteogenic differentiation of human BMSCs (hBMSCs) using real-time PCR and Western blot. We delivered Chordin siRNA to hBMSCs using a previously reported cationic polymer, polyspermine imidazole-4,5-imine (PSI), as a pH responsive and non-cytotoxic transfection agent. The apoptosis and cellular uptake efficiency were analysed by flow cytometry. RESULTS: We identified Chordin as the most appropriate potential therapeutic target gene for enhancing the osteogenic differentiation of hBMSCs. Chordin knockdown rescued the osteogenic capacity of hBMSCs isolated from patients with bone nonunion. Highly efficient knockdown of Chordin was achieved in hBMSCs using PSI. Chordin knockdown promoted hBMSC osteogenesis and bone regeneration in vitro and in vivo. CONCLUSIONS: Our results suggest that Chordin is a potential target for improving osteogenesis and bone nonunion therapy and that responsive and non-toxic cationic polyimines such as PSI are therapeutically feasible carriers for the packaging and delivery of Chordin siRNA to hBMSCs. PMID- 29587277 TI - Mitofusin-2 Triggers Cervical Carcinoma Cell Hela Apoptosis via Mitochondrial Pathway in Mouse Model. AB - BACKGROUND/AIMS: Cervical carcinoma continues to be one of the most dangerous cancer types, and more effective therapies are urgently needed for cervical carcinoma treatment. Mitochondria-associated Mitofusin 2 has influence on the progression of many cancers. In the current study, we aimed to focus on the cell apoptotic effects of Mfn2 on cervical carcinoma HeLa cells in vitro and to try to explore its underlying mechanisms. Moreover, we investigated the anticancer potential of Mfn2 in a cervical carcinoma mouse model. METHODS: Adenovirus-Mfn2 (Adv-Mfn2) was used to deliver mfn2 into HeLa cells and tumour tissues in a nude mouse model. CCK-8, TUNEL assay, Western blot and immunohistochemical staining were performed to detect the effects of Mfn2. The mRNA level of Mfn2 was determined by quantitative realtime PCR (qRT-PCR) analysis. The effect of Mfn2 on cell apoptosis was investigated by flow cytometry. Flow cytometry was used to assess the change of the mitochondrial membrane potential of the cells treated with JC-1 assay. Mfn2, Bax, Bcl-2, cytochrome c, cleaved caspase-3, and cleaved caspase-9 protein levels were analysed by Western blot. RESULTS: Data from CCK-8 and flow cytometry showed that Mfn2 could inhibit proliferation and induce apoptosis in a dose- and time-dependent manner in HeLa cells. JC-1 test results revealed that the membrane potential of the mitochondrial decreased in a dose dependent manner in HeLa cells after Adv-Mfn2 treatment. The data from Western blot confirmed that higher cytosolic amounts of cytochrome c with increasing doses of Adv-Mfn2 signified the onset of the intrinsic apoptotic pathway. Levels of cleaved caspase-3 and cleaved caspase-9 increased in HeLa cells with Adv-Mfn2 treatment. We also found significant increases in the Bax level and a decreased Bcl-2 level with Adv-Mfn2 treatment. We further confirmed that Mfn2 could significantly inhibit the growth of the cervical tumour in the xenografted cervical carcinoma mouse model. After a 9-day-treatment, the tumours of the Adv mfn2 group were inhibited and induced into apoptosis. The results demonstrated that the overexpression of Mfn2 could not only increase the levels of Bax and Bid in cervical tumour cells but also decrease the phosphorylation of Bad and the expression of Bcl-2. CONCLUSION: These studies suggested that the overexpression of Mfn2 could trigger cervical tumour apoptosis in vitro and in vivo, which was related to the mitochondrial pathway, and may provide a new treatment target for cervical carcinoma. PMID- 29587278 TI - A Risk-Adapted Approach to Patients with Stage I Seminoma according to the Status of Rete Testis: The Fourth Spanish Germ Cell Cancer Group Study. AB - OBJECTIVE: The aim of this study was to assess a risk-adapted strategy for stage I seminoma guided by the presence of rete testis invasion. METHODS: Between January 2013 and December 2015, a total of 135 consecutive patients with stage I seminoma from 18 Spanish tertiary hospitals were included in a prospective multicenter study. Median patient age was 38 years (range 22-60). Preoperative beta-human chorionic gonadotropin was elevated in 9.6% of patients. Rete testis invasion was present in 47.4% of patients. After orchiectomy, subjects with rete testis invasion were treated with 2 courses of adjuvant carboplatin (area under the curve of 7, with 21-day interval). Those without this risk factor were managed by surveillance. Disease-free survival (DFS) and overall survival (OS) were estimated with the Kaplan-Meier method. RESULTS: After a median follow-up time of 33 months, only 6 relapses were recorded (5 on surveillance, 1 after carboplatin). These cases were rescued with BEP or EP chemotherapy, and all 135 patients are currently disease free without sequelae. Three-year DFS was 92.0 and 98.2% for patients on surveillance and after carboplatin, respectively. Three year OS was 100%. CONCLUSION: A risk-adapted approach based on rete testis invasion as a single risk factor is feasible and yielded an excellent outcome with a 3-year DFS of 94.9%.

PMID- 29587280 TI - Inhibition of Cgkii Suppresses Seizure Activity and Hippocampal Excitation by Regulating the Postsynaptic Delivery of Glua1. AB - BACKGROUND/AIMS: The imbalance between excitation and inhibition is a defining feature of epilepsy. GluA1 is an AMPA receptor subunit that can strengthen excitatory synaptic transmission when upregulated in the postsynaptic membrane, which has been implicated in the pathogenesis of epilepsy. cGKII, a cGMP dependent protein kinase, regulates the GluA1 levels at the plasma membrane. METHODS: To explore the role of cGKII in epilepsy, we investigated the expression of cGKII in patients with temporal lobe epilepsy (TLE) and in a pilocarpine induced rat model and then performed behavioral, histological, and electrophysiological analyses by applying either a cGKII agonist or inhibitor in the hippocampus of the animal model. RESULTS: cGKII expression was upregulated in the epileptogenic brain tissues of both humans and rats. Pharmacological activation or inhibition of cGKII induced changes in epileptic behaviors in vivo and epileptic discharges in vitro. Further studies indicated that cGKII activation disrupted the balance of excitation and inhibition due to strengthened AMPAR-mediated excitatory synaptic transmission. Moreover, cGKII regulated epileptic seizures by phosphorylating GluA1 at Ser845 to modulate the expression and function of GluA1 in the postsynaptic membrane. CONCLUSION: These results suggest that cGKII plays a key role in seizure activity and could be a potential therapeutic target for epilepsy. PMID- 29587282 TI - Can a Non-Native Primate Be a Potential Seed Disperser? A Case Study on Saimiri sciureus in Pernambuco State, Brazil. AB - The interaction between native fleshy-fruit plants and introduced fruit consumers contributes to the dynamics of highly fragmented environments. Such interactions can occur through pollination and seed dispersal. Here, we investigated the potential of seed dispersing by a non-native primate, the squirrel monkey (Saimiri sciureus), in an urban Atlantic forest fragment in north-eastern Brazil. Fleshy fruits from non-native plants were preferentially exploited by the squirrel monkeys. We measured 147 seeds (width and length) from 20 of 106 faecal samples. The dispersed seeds were from five plant species (four families). We found a positive correlation between the size of seeds found in faecal samples with their availability in the habitat. Only one seed was found visually damaged after passage through the squirrel monkeys' guts. The defecated seeds were uniformly distributed (variance to mean ratio index) in the home range of squirrel monkeys, and there was a lack of specific latrines (i.e., habitat preference for defecation). Our data provide evidence that non-native S. sciureus may in be (i) acting as a potential seed disperser of native plants in the Atlantic forest fragment, (ii) contributing to the ecological role of native frugivores, and (iii) potentially contributing to the regeneration process of the highly degraded study site. PMID- 29587281 TI - MicroRNA-183 Acts as a Tumor Suppressor in Human Non-Small Cell Lung Cancer by Down-Regulating MTA1. AB - BACKGROUNDS/AIMS: MicroRNAs (miRs) often contribute to the progression of non small cell lung cancer (NSCLC) via regulation of mRNAs that are involved in lung homeostasis. We conducted a study aimed at exploring the roles of miR-183 in the proliferation, epithelial-mesenchymal transition (EMT), invasion and migration of human NSCLC cells via targeting MTA1. METHODS: NSCLC and adjacent normal tissues were collected from 194 patients with NSCLC. Positive expression of MTA1 protein was detected by immunohistochemistry. The highest levels of expression of miR-183 were detected using RT-qPCR in SPC-A-1 cells, which were selected and assigned to the following groups: blank, negative control (NC), miR-183 mimic, miR-183 inhibitor, siRNA-MTA1, and miR-183 inhibitor + siRNA-MTA1. The expression of miR 183 and the mRNA and protein expression of MTA1, E-cadherin, Vimentin, Snail, PCNA, Bax and Bcl-2 in tissues and transfected cells were measured using RT-qPCR and western blot analysis. Cell proliferation, apoptosis, migration and invasion were evaluated by CCK-8, flow cytometry, scratch tests and Transwell assays. Tumor xenografts were conducted in nude mice to determine tumor growth. RESULTS: SPC-A-1 cells with the highest levels of miR-183 expression were selected. Compared with adjacent normal tissues, the expression of miR-183 and the mRNA and protein expression of E-cadherin and Bax were decreased in NSCLC tissues, while mRNA and protein expression of MTA1, Vimentin, snail, PCNA and Bcl-2 were increased. MiR-183 was over-expressed in the miR-183 mimic group and under expressed in the miR-183 inhibitor and miR-183 inhibitor + siRNA-MTA1 groups. In the miR-183 mimic and siRNA-MTA1 groups, the mRNA and protein expression of E cadherin and Bax, as well as cell apoptosis, were enhanced, while the expression levels of MTA1, Vimentin, snail, PCNA and Bcl-2 mRNA and protein, cell proliferation, migration, invasion and tumor growth were reduced relative to the blank and NC groups. The miR-183 inhibitor group exhibited an opposite trend. CONCLUSION: Our study indicates that miR-183 down-regulates MTA1 to inhibit the proliferation, EMT, migration and invasion of human NSCLC cells. PMID- 29587283 TI - Old and New Gut Hormone, Gastrin and Acid Suppressive Therapy. AB - Gastrin acts physiologically as a gut hormone to stimulate acid secretion after meal and as a cell-growth factor of oxyntic mucosa. Increase in serum gastrin level happens under various conditions including Zollinger-Ellison syndrome, antral G cell hyperplasia, autoimmune gastritis, atrophic gastritis, renal failure, vagotomy, Helicobacter pylori infection and acid suppressive therapy. As acid suppressive therapy causes hypergastrinemia, the association between acid suppressive therapy and gastric neuroendocrine cell tumor (NET) has been discussed during the past 30 years. In this review article, the definition of hypergastrinemia and the related disorders including acid suppressive therapy and gastric NET are discussed.

PMID- 29587284 TI - Electrical Stimulation Enhances Migratory Ability of Transplanted Bone Marrow Stromal Cells in a Rodent Ischemic Stroke Model. AB - BACKGROUND/AIMS: Bone marrow stromal cells (BMSCs) transplantation is an important strategy for the treatment of ischemic stroke. Currently, there are no effective methods to guide BMSCs toward the targeted site. In this study, we investigated the effect of electrical stimulation on BMSCs migration in an ischemic model of rats. METHODS: Adult male Wistar rats weighing 200 to 250 g received right middle cerebral artery occlusion (MCAO) for 90 minutes. BMSCs (2.5*105 cells/ 4 ul PBS) were stereotaxically injected into the left corpus callosum at 1 day after MCAO. After BMSCs injection, a plate electrode with a diameter of 3 mm connected to an implantable electrical stimulator was placed on the right frontal epidural space and a counter electrode was placed in the extra cranial space. Electrical stimulation at preset current (100 uA) and frequency (100 Hz) was performed for two weeks. Behavioral tests were performed at 1, 4, 8, and 15 days after MCAO using the modified Neurological Severity Score (mNSS) and cylinder test. Rats were euthanized at 15 days after MCAO for evaluation of infarction area and the migration distance and area of BMSCs found in the brain tissue. After evaluating cell migration, we proceeded to explore the mechanisms guiding these observations. MCAO rats without BMSCs transplantation were stimulated with same current and frequency. At 1 and 2 weeks after MCAO, rats were euthanized to evaluate stromal cell-derived factor 1 alpha (SDF-1alpha) level of brain tissues in the bilateral cortex and striatum. RESULTS: Behavioral tests at 4, 8, and 15 days after MCAO revealed that stimulation group displayed significant amelioration in mNSS and cylinder test compared to control group (p<0.05). Similarly, the infarction areas of stroke rats in stimulation group were significantly decreased compared to control group (p<0.05). Migration distance and area of transplanted BMSCs were significantly longer and wider respectively in stimulation group. An increased concentration gradient of SDF 1alpha in stimulation group accompanied this enhanced migration of transplanted cells. CONCLUSIONS: These results suggest that electrical stimulation enhances migratory ability of transplanted BMSCs in ischemic stroke model of rats. If we can direct the implanted BMSCs to the site of interest, it may lead to a greater therapeutic effect. PMID- 29587286 TI - Chromosome Banding in Amphibia. XXXVII. Y-Autosome Translocations in Anura. AB - A detailed cytogenetic study on anurans belonging to the unranked taxon Terraranae revealed the existence of microscopically recognizable XY?/XX? or ZZ?/ZW? sex chromosomes in 11 species. Furthermore, in some species Y-autosome translocations were found, of which 5 could be confirmed. The male individuals carrying the Y-autosome translocations still coexist with the males showing the original karyotypes. The present report gives an overview on the mitotic and meiotic structure, staining and banding properties, functional importance, and similarities and differences of these Y-autosome translocations which are very rare in vertebrates. A mathematical model was constructed that calculates the various probabilities of further chromosome rearrangements in these karyotypes with Y-autosome translocations. The localization of the differential segment containing the hypothetical male sex-determining gene in the Y chromosome is discussed. PMID- 29587287 TI - Cohesin RAD21 Gene Promoter Methylation in Patients with Chronic Lymphocytic Leukemia. AB - Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in adults and is characterized by the presence of specific cytogenetic abnormalities. CLL research has been focused on epigenetic processes like gene promoter methylation of CpG islands. In the present study, the methylation status of the RAD21 gene is studied and associated with cytogenetic findings in CLL patients in order to investigate its possible implication in CLL pathogenesis and the formation of CLL chromosomal abnormalities. PMID- 29587288 TI - Effect of Sodium Thiosulfate on Arterial Stiffness in End-Stage Renal Disease Patients Undergoing Chronic Hemodialysis (Sodium Thiosulfate-Hemodialysis Study): A Randomized Controlled Trial. AB - BACKGROUND: Arterial stiffness (AS) and vascular calcification are significantly related to a high cardiovascular mortality risk in hemodialysis (HD) patients. Intravenous sodium thiosulfate (IV STS) can prevent and delay the vascular calcification progression in uremic states; however, the STS effect on AS has not been assessed. This study aimed to evaluate the STS efficacy on vascular calcification and AS in HD patients. METHODS: Fifty HD patients with abnormal AS, as measured via the cardio-ankle vascular index (CAVI >=8), were prospectively randomized to open-label 12.5 g IV STS during the last HD hour twice weekly for 6 months (n = 24) or the usual care (control group; n = 26). Patients and treating physicians were not blinded. The CAVI, coronary artery calcification (CAC) score, hemodynamics, and biochemical parameters were measured at the baseline and at 3 and 6 months. RESULTS: All the baseline parameters were comparable. The IV STS significantly reduced the CAVI when compared to the control group (mean CAVI difference = -0.53; 95% CI -1.00 to -0.06; p = 0.03). A significant CAVI improvement was seen in those patients without diabetes mellitus. The natural logarithm of the CAC volume score was significantly increased in the control group. The high sensitivity C-reactive protein level was slightly lowered in the IV STS group (not significant). CONCLUSION: The intradialytic STS treatment significantly reduced the AS, as measured by the CAVI, and stabilized the vascular calcification in the HD patients. STS may be a novel therapeutic strategy for delaying and treating the structural and functional vascular wall abnormalities in HD patients. PMID- 29587289 TI - Fisetin Protects against Intracerebral Hemorrhage-Induced Neuroinflammation in Aged Mice. AB - BACKGROUND: Fisetin is commonly used as an anti-inflammatory and neuroprotective drug. In this study, we aimed to investigate the efficacy of fisetin in alleviating intracerebral hemorrhage (ICH)-induced brain injury. METHODS: Mouse ICH models were constructed using the collagenase-induction method. ICH mice received fisetin treatment at the dose of 10-90 mg/kg, followed by the evaluation of neurological deficit through neurologic severity scores (mNSS), brain water content and terminal deoxynucleotidyl transferase dUTP nick end labeling analysis of cell apoptosis. Cytokine levels were also assessed with enzyme-linked immunosorbent assay. The activation of astrocytes and microglia was evaluated through S100 staining and Western blot analysis of ionized calcium-binding adaptor molecule 1 respectively. Nuclear factor kappa-B (NF-kappaB) signaling was also evaluated by Western blot. RESULTS: ICH mice demonstrated dramatic increase in mNSS, brain edema and cell apoptosis, indicating severe brain deficit. Fisetin treatment lowered these parameters, suggesting the alleviation of brain injury. Levels of proinflammatory cytokines were reduced, accompanied by a prominent decrease in activated astrocytes and microglia. NF-kappaB signaling was also attenuated by fisetin treatment. CONCLUSION: Fisetin effectively alleviates ICH by downregulating proinflammatory cytokines and attenuating NF-kappaB signaling. These data suggest fisetin as a valuable natural flavonol for clinical management of ICH-induced brain injury. PMID- 29587290 TI - Chemoprevention and Treatment of Pancreatic Cancer: Update and Review of the Literature. AB - BACKGROUND: Pancreatic ductal adenocarcinoma is one of the most lethal types of cancer with a 5-year survival rate of around 7%. Due to the relatively poor prognosis, the potential need of an effective chemoprevention is highly needed. SUMMARY: Different risk factors like smoking or hereditary tumour syndromes should be known for early detection of pancreatic intraepithelial neoplasia. Chemopreventive dietary agents include curcumin, capsaicin and flavonoid, whereas potential chemopreventive drugs compromise aspirin, metformin or statins. This review aims to give an overview on potential risk factors for the development of pancreatic cancer. Furthermore, we try to summarise known chemopreventive agents to support the fight against this lethal disease. Key Messages: On the one hand, there are natural agents that exhibit preventive properties and can lead to the prohibition of pancreatic cancer. On the other hand, there are drugs and agents that are currently used in other contexts and are thus already approved and studied in terms of their mechanisms of effects and the related secondary effects. PMID- 29587291 TI - Retinoic Acid Increases Fatty Acid Oxidation and Irisin Expression in Skeletal Muscle Cells and Impacts Irisin In Vivo. AB - BACKGROUND/AIMS: All-trans retinoic acid (ATRA) has protective effects against obesity and metabolic syndrome. We here aimed to gain further insight into the interaction of ATRA with skeletal muscle metabolism and secretory activity as important players in metabolic health. METHODS: Cultured murine C2C12 myocytes were used to study direct effects of ATRA on cellular fatty acid oxidation (FAO) rate (using radioactively-labelled palmitate), glucose uptake (using radioactively-labelled 2-deoxy-D-glucose), triacylglycerol levels (by an enzymatic method), and the expression of genes related to FAO and glucose utilization (by RT-real time PCR). We also studied selected myokine production (using ELISA and immunohistochemistry) in ATRA-treated myocytes and intact mice. RESULTS: Exposure of C2C12 myocytes to ATRA led to increased fatty acid consumption and decreased cellular triacylglycerol levels without affecting glucose uptake, and induced the expression of the myokine irisin at the mRNA and secreted protein level in a dose-response manner. ATRA stimulatory effects on FAO related genes and the Fndc5 gene (encoding irisin) were reproduced by agonists of peroxisome proliferator-activated receptor beta/delta and retinoid X receptors, but not of retinoic acid receptors, and were partially blocked by an AMP dependent protein kinase inhibitor. Circulating irisin levels were increased by 5 fold in ATRA-treated mice, linked to increased Fndc5 transcription in liver and adipose tissues, rather than skeletal muscle. Immunohistochemistry analysis of FNDC5 suggested that ATRA treatment enhances the release of FNDC5/irisin from skeletal muscle and the liver and its accumulation in interscapular brown and inguinal white adipose depots. CONCLUSION: These results provide new mechanistic insights on how ATRA globally stimulates FAO and enhances irisin secretion, thereby contributing to leaning effects and improved metabolic status. PMID- 29587293 TI - Effects of MiR-375-BMPR2 as a Key Factor Downstream of BMP15/GDF9 on the Smad1/5/8 and Smad2/3 Signaling Pathways. AB - BACKGROUND/AIMS: Bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9), which are secreted by oocytes, are important regulators of follicular growth and development and ovarian function. These two factors can regulate the proliferation and apoptosis of cumulus cells via modulation of the Smad signaling pathway. Studies have shown that BMP15 and GDF9 can affect the level of miR-375, whereas the target gene of miR-375 is BMPR2, the type II receptor of BMP15 and GDF9. However, whether or how the BMP15/ GDF9-miR-375-BMPR2 pathway affects the proliferation and apoptosis of bovine cumulus cells through regulation of the Smad signaling pathway remains unclear. METHODS: In this study, cumulus cells were first obtained from cumulus-oocyte complexes (COCs). Appropriate concentrations of BMP15 and GDF9 were added during the in vitro culture process. Cell Counting Kit-8 (CCK-8) analyses and flow cytometry were used to determine the effects of BMP15/GDF9 on bovine cumulus cells proliferation and apoptosis. Subsequently, miR-375 mimics, miR-375 inhibitor and BMPR2 siRNA were synthesized and used for transfection experiments. Western Blot analysis was used to detect changes before and after transfection in the expression levels of the BMP15/GDF9 type I receptors ALK4, ALK5 and ALK6; the phosphorylation levels of Smad2/3 and Smad1/5/8, which are key signaling pathway proteins downstream of BMP15/GDF9; the expression levels of PTX3, HAS2 and PTGS2, which are key genes involved in cumulus cells proliferation; and Bcl2/Bax, which are genes involved in apoptosis. RESULTS: The addition of 100 ng/mL BMP15 or 200 ng/mL GDF9 or the combined addition of 50 ng/mL BMP15 and 100 ng/mL GDF9 effectively inhibited bovine cumulus cell apoptosis and promoted cell proliferation. BMP15/GDF9 negatively regulated miR-375 expression and positively regulated BMPR2 expression. High levels of miR-375 and inhibition of BMPR2 resulted in increased expression of ALK4 and decreased expression of PTX3, HAS2 and PTGS2, whereas miR 375 inhibition resulted in the opposite results. BMP15 and GDF9 significantly activated the levels of p-Smad2/3 and p-Smad1/5/8, whereas miR-375 inhibited the levels of p-Smad2/3 and p-Smad1/5/8 by negatively regulating BMPR2 and also led to apoptosis. CONCLUSION: BMP15 and GDF9 have synergistic effects and can act through miR-375 to affect the expression levels of type I receptor ALK4 and type II receptor BMPR2 and the activation of Smad signaling pathway, which subsequently affected the proliferation, spread and apoptosis of cumulus cells. PMID- 29587294 TI - Macroscopic Localized Subicular Thinning as a Potential Indicator of Amyotrophic Lateral Sclerosis. AB - Subicular degeneration occurs in amyotrophic lateral sclerosis (ALS) patients. However, it was unknown whether microscopic subicular degeneration could be observed as macroscopic changes and whether these changes were associated with the transactive-response DNA binding protein 43 kDa (TDP-43) pathology. Topographic differences between subicular degeneration caused by ALS and Alzheimer disease (AD) had also not been characterized. Here we investigated the subiculum and related areas in autopsied brains from 3 ALS and 3 AD patients. Macroscopic subicular thinning and corresponding astrocytosis were pronounced in ALS compared to AD. This thinning was frequently accompanied by TDP-43 pathology in the transentorhinal cortex and nucleus accumbens. The preferential susceptibility of the perforant pathway to TDP-43 deposition may be an underlying cause of subicular thinning in ALS. PMID- 29587295 TI - Helicobacter pylori Eradication Therapy Ameliorates Latent Digestive Symptoms in Chronic Atrophic Gastritis. AB - BACKGROUND/AIMS: This study investigated the effect of Helicobacter pylori eradication therapy on latent digestive symptoms in chronic atrophic gastritis. METHODS: We enrolled 650 health checkup patients who underwent eradication therapy for chronic gastritis and completed a self-report questionnaire before and after the treatment between January 2014 and December 2016 at the Japanese Red Cross Society Kyoto Daiichi Hospital. RESULTS: H. pylori eradication therapy for chronic atrophic gastritis improved latent digestive symptoms, including both the acid reflux and dyspepsia components in the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) scores. The effect was sustained until 1 year after the treatment. Higher FSSG scores (>=8 points) before H. pylori eradication therapy and age <70 years were significantly associated with the improvement of digestive symptoms after H. pylori eradication therapy. CONCLUSION: H. pylori eradication therapy may improve patients' quality of life through the resolution of latent abdominal symptoms. PMID- 29587296 TI - The Relationships of the Fractional Excretion of Uric Acid with Brachial-Ankle Pulse Wave Velocity and Ankle Brachial Index in Chinese Young Adults. AB - BACKGROUND/AIMS: Elevated serum uric acid (UA) was intimately correlated with vascular stiffness and abnormal ankle brachial index (ABI) in various populations. These correlations lost significance after adjustment for estimated glomerular filtration rate (eGFR), indicating that the association of UA and brachial-ankle pulse wave velocity (baPWV) or ABI might be driven by kidney function. UA is predominantly eliminated through the kidneys, and metabolic disorders can influence the clearance of UA. In this study, we aimed to explore the putative correlation between FEUA and baPWV or ABI to determine to what extent the associations with UA were affected by renal function. METHODS: This cross-sectional study enrolled 2351 participants, who underwent general health screening in Hanzhong people's hospital from March to June of 2017. BaPWV and ABI were measured using a volume-plethysmographic apparatus (BP-203RPEII; Nihon Colin, Tokyo, Japan). FEUA was divided into quartiles: Q1:FEUA<=3.07; Q2: 3.07 9.19. RESULTS: Lower FEUA predicted a higher prevalence of high baPWV and low ABI (p for trend <0.001). The respective ORs for high baPWV from the first to the third quartiles of FEUA were 1.777(1.323, 2.387); 1.561(1.158, 2.104); and 1.680 (1.250, 2.259). The prevalence of low ABI was greatly elevated with the decrement of FEUA [ORs for the first to third FEUA quartiles were 6.977(2.062, 23.610); 5.123(1.475, 17.790); and 2.685(0.709, 10.171), respectively]. The association of FEUA and ABI was independent of related confounding factors. However, the association between FEUA and baPWV was greatly influenced by corresponding confounders, especially gender. The efficacy of FEUA in the prediction of low ABI was stronger than that of serum UA. However, serum UA was more powerful in the prediction of high baPWV. CONCLUSION: Kidney function exerted a profound influence on the relationship between UA and baPWV or ABI, revealing complex interactions among cardiovascular risk factors. PMID- 29587297 TI - A Prospective Trial of Nebulized Amikacin in the Treatment of Bronchiectasis Exacerbation. AB - BACKGROUND: Pseudomonas aeruginosa is the most common pathogenic bacteria in bronchiectasis (BE) patients. The availability and security of nebulized amikacin treatment are unknown. OBJECTIVE: The purpose of this study was to explore the efficiency and adverse effects of nebulized amikacin treatment for 2 weeks, administered as intravenous therapy during exacerbation of BE patients infected with P. aeruginosa. METHODS: A total of 143 patients with exacerbation of BE were screened between January 2013 and March 2016 at five tertiary hospitals in Shandong Province, China. The BE patients were diagnosed by high-resolution computed tomography scans, and all of them were confirmed to be infected with P. aeruginosa after sputum culture test. Seventy-four patients were assigned to the intervention group and received amikacin nebulization (0.2 g) treatment twice daily for 2 weeks along with intravenous antibiotic therapy. Sixty-nine patients were assigned to the control group and received standard antibiotic therapy alone. The primary outcome was the rate of bacterial eradication from the sputum, and the secondary outcomes were drug resistance and adverse effects. RESULTS: The bacterial eradication rate of sputum in the intervention group (51.4%) was significantly higher compared to that in the control group (23.2%) (chi2 = 14.211, p = 0.030). Drug sensitivity testing showed that there were 5 drug resistant cases in the intervention group and 7 in the control group, which was not significantly different. Three patients dropped out of the trial due to adverse effects. None of the patients hat renal injury. CONCLUSIONS: Nebulized amikacin treatment is a safe treatment for exacerbation of BE and significantly increases the bacterial eradication rate of sputum.

AB - BACKGROUND/AIMS: Epidermal growth factor receptor variant III (EGFRvIII), the most frequent EGFR variant, is constitutively activated without binding to EGF and is correlated with a poor prognosis. CH12, a human-mouse chimeric monoclonal antibody, has been developed in our laboratory and selectively binds to overexpressed EGFR and EGFRvIII. A previous study had reported that EGFR could influence autophagic activity, and autophagy is closely related to tumor development and the response to drug therapy. In this study, we aimed to elucidate the effect of CH12 on autophagy and efficacy of combining CH12 with an autophagy inhibitor against EGFRvIII-positive tumors. METHODS: EGFRvIII was overexpressed in liver cancer, glioblastoma and breast cancer, and the change in the autophagy-relevant protein levels was analyzed by western blot assays, LC3 punctate aggregation was analyzed by immunofluorescence. The interaction of Beclin-1 and Rubicon was assessed by co-immunoprecipitation (Co-IP) after CH12 treatment. The efficacy of ATG7 or Beclin-1 siRNA in combination with CH12 in Huh 7-EGFRvIII cells was assessed by CCK-8 assays. The autophagy and apoptosis signaling events in Huh-7-EGFRvIII cells upon treatment with control, CH12, siRNA or combination for 48 h were assessed by western blot assays. RESULTS: Our results showed that, in cancer cell lines overexpressing EGFRvIII, only the liver cancer cell lines Huh-7 and PLC/PRF/5 suggested autophagy activation. We then investigated the mechanism of autophagy activation after EGFRvIII overexpression. The results showed that EGFRvIII interacted with Rubicon, an autophagy inhibition protein, and released Beclin-1 to form the inducer complex, thus contributing to autophagy. In addition, CH12, via inhibiting the phosphorylation of EGFRvIII, promoted the interaction of EGFRvIII with Rubicon, further inducing autophagy. In vitro assays suggested that knocking down the expression of the key proteins ATG7 or Beclin-1 in the autophagy pathway with siRNA inhibits tumor cell proliferation. Combining autophagy-related proteins 7 (ATG7) or Beclin-1 siRNA with CH12 in Huh-7-EGFRvIII cells showed better inhibition of cell proliferation. CONCLUSION: EGFRvIII could induce autophagy, and CH12 treatment could improve autophagy activity in EGFRvIII-positive liver cancer cells. The combination of CH12 with an autophagy inhibitor or siRNA against key proteins in the autophagy pathway displayed more significant efficacy on EGFRvIII-positive tumor cells than monotherapy, and induced cell apoptosis. PMID- 29587299 TI - Chronic Obstructive Pulmonary Disease in Lung Cancer Patients: Prevalence, Underdiagnosis, and Clinical Characterization. AB - BACKGROUND: Lung cancer (LC) and chronic obstructive pulmonary disease (COPD) are associated with increased morbidity and mortality. The differential clinical and functional features among LC patients with or without COPD have not been defined. OBJECTIVES: The aims of this study were to examine the prevalence and underdiagnosis rate of COPD in LC patients and to compare the clinical and functional features of LC patients with and without COPD. METHODS: We designed a multicenter hospital-based study including all LC cases diagnosed from January 2014 to August 2016. We assessed epidemiological, clinical, radiological, functional, and histological variables in all cases. RESULTS: We recruited 602 patients with LC, most of them men (77.9%), with a median age of 67 +/- 15 years. The COPD prevalence among LC patients was 51.5%, with a underdiagnosis rate of 71.6%. The LC+COPD patients were older and the proportion of men was higher compared with the LC-only patients. The LC+COPD patients had more pack-years, more squamous LC, a lower monoxide transfer coefficient (KCO), and higher Charlson index scores than patients with LC only. The median survival of LC-only patients was 37% longer than that of LC+COPD patients (22 vs. 16 months), but this difference was not statistically significant. CONCLUSIONS: Among LC patients, COPD is prevalent and underdiagnosed. Patients with LC+COPD more often have squamous LC, have greater comorbidities, and have a lower KCO. More effort should be made for an early diagnosis of COPD to select patients at higher risk of developing LC. PMID- 29587300 TI - Audiology Students' Perspectives of Enacting and Learning Clinical Communication: A Qualitative Interview and Video Reflexivity Study. AB - Purpose: Effective clinical communication is pivotal to the provision of quality hearing health care. To date, audiology students reportedly felt ill-prepared when counseling patients about their hearing impairment, yet there is a paucity of studies exploring how clinical communication is taught and learned in audiology programs. Thus, the aims of the study were (a) to explore final year audiology students' perspectives of their own clinical communication skills during an in-house university clinical placement and (b) to explore students' perceptions of their clinical communication education. Method: Using a qualitative description approach, students were asked to coview their filmed clinical encounter using video reflexivity during a semistructured interview on clinical communication education. Fifteen final year graduate audiology students from The University of Melbourne, Australia, participated in the study. The interviews were audio-recorded and analyzed thematically. Results: The overarching themes of striving to be patient-centered, assessment shapes behavior, and power relations emerged from students' reflection of their own clinical encounter. In addition, the theme what students want described the perceived teaching methods that assisted students' clinical communication practices. Conclusions: The findings of this study highlight the challenges that students perceived during their clinical placement as they strive to enact a patient-centered interaction. An assessment rubric that incorporates communication skills can provide greater opportunities for feedback and self reflection. Additionally, clinical communication education that adopts experiential learning and is longitudinally integrated into the curriculum can further reinforce students' communication learning needs. PMID- 29587301 TI - The Effects of Parent Training on Vocabulary Scores of Young Children With Hearing Loss. AB - Purpose: The purpose of this study is to evaluate the effects of short-term parent training on maternal use of language stimulation strategies and vocabulary scores in children with hearing loss. Method: Six mother-child dyads participated in the multiple-baseline study. During baseline and maintenance, children engaged in a business-as-usual model of clinician-only therapy. During intervention, mothers and children participated in parent training focused on transparent labeling and linguistic mapping strategies. Parent strategy use was measured via weekly play-based probe assessments. Child vocabulary growth was measured via parent report. Results: A relation between parent training and use of transparent labeling was established for all mothers, and a relation between parent training and use of linguistic mapping was established for 3 of 6 mothers. Child vocabulary growth rate increased from baseline to intervention in 4 of 6 children. Conclusions: Short-term parent training can change parent behavior. However, parents may not maintain these skills without support. Further research is needed to characterize the extent to which short-term training can make long term changes in parent and child outcomes. PMID- 29587304 TI - Vocal Emotion Identification by Children Using Cochlear Implants, Relations to Voice Quality, and Musical Interests. AB - Purpose: Listening tests for emotion identification were conducted with 8-17-year old children with hearing impairment (HI; N = 25) using cochlear implants, and their 12-year-old peers with normal hearing (N = 18). The study examined the impact of musical interests and acoustics of the stimuli on correct emotion identification. Method: The children completed a questionnaire with their background information and noting musical interests. They then listened to vocal stimuli produced by actors (N = 5) and consisting of nonsense sentences and prolonged vowels ([a:], [i:], and [u:]; N = 32) expressing excitement, anger, contentment, and fear. The children's task was to identify the emotions they heard in the sample by choosing from the provided options. Acoustics of the samples were studied using Praat software, and statistics were examined using SPSS 24 software. Results: The children with HI identified the emotions with 57% accuracy and the normal hearing children with 75% accuracy. Female listeners were more accurate than male listeners in both groups. Those who were implanted before age of 3 years identified emotions more accurately than others (p < .05). No connection between the child's audiogram and correct identification was observed. Musical interests and voice quality parameters were found to be related to correct identification. Conclusions: Implantation age, musical interests, and voice quality tended to have an impact on correct emotion identification. Thus, in developing the cochlear implants, it may be worth paying attention to the acoustic structures of vocal emotional expressions, especially the formant frequency of F3. Supporting the musical interests of children with HI may help their emotional development and improve their social lives. PMID- 29587306 TI - The Impact of Lexical Characteristics and Noise on Intelligibility of Parkinsonian Speech. AB - Purpose: This study investigated the impact of lexical characteristics on the intelligibility of speakers with Parkinson's disease (PD). Intelligibility was compared for listening in a quiet versus a noisy environment. Method: A total of 192 young listeners participated in the study, with 96 listeners listening in quiet and 96 listening in noise in which the spoken sentences were mixed with 10 talker babble. The listeners transcribed spoken sentences with target words controlled for word frequency and neighborhood density. The sentences were produced by 12 speakers with PD and 12 healthy control (HC) speakers. Transcription accuracy was compared across lexical categories between PD and HC and between the two listening conditions. Results: Transcription accuracy was higher for high-frequency words than low-frequency words for both speaker groups in quiet and in noise. The neighborhood density effect was evident only in the noise condition with better intelligibility for words from sparse neighborhoods than from dense neighborhoods. Regardless of listening condition, the PD group was less intelligible with a significant decrease in intelligibility in noise relative to quiet. Conclusions: The lexical properties of the words affected listeners' understanding of Parkinsonian speech. Frequent words in sparse neighborhood enhanced intelligibility, especially under adverse listening conditions. Babble noise had a detrimental impact on the intelligibility of Parkinsonian speech. The extent of the lexical effect on intelligibility increased in noise. PMID- 29587307 TI - Measuring the Diagnostic Features of Social (Pragmatic) Communication Disorder: An Exploratory Study. AB - Purpose: The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition introduced a new neurodevelopmental disorder, social (pragmatic) communication disorder (SPCD), that is characterized by deficits in 4 areas of communication. Although descriptions of these areas are provided, no assessment tools for SPCD are recommended. The purpose of this study was to examine the extent to which items from measurement tools commonly used in assessing pragmatic language impairment and related disorders might be useful in assessing the characteristics of social communication that define SPCD in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Method: Based on a literature search, 594 items from assessment tools commonly used to measure social communication abilities in people with pragmatic language impairment were identified. The first author judged whether each item reflected 1, more than 1, or none of the 4 SPCD diagnostic characteristics. After a brief training process, 5 second raters independently mapped subsets of items to the 6 categories. We calculated the percentage of agreement and Cohen's kappa for each pair of raters in assigning items to categories. Results: Percentages of agreement ranged from 76% to 82%, and Cohen's kappa values ranged from .69 to .76, indicating substantial agreement. Sources and item numbers for the 206 items that both raters assigned to the same SPCD feature are provided. Conclusions: These items may provide guidance in assessing SPCD and in designing standardized screening and diagnostic measures for SPCD. PMID- 29587311 TI - ? PMID- 29587312 TI - ?

AB - The approval of immune checkpoint inhibitors has started a new era in the treatment of urothelial carcinoma, which, so far, has been a disease with limited treatment options. However, in the current German S3 guideline for bladder cancer the remarkable improvements provided by immune checkpoint inhibitors have not been reflected. As cancer immunotherapy is a novel approach, there are several questions related to the daily clinical routine: What clinical data was used as the basis for the approval of the individual substances? What does this mean for previous treatment algorithms? What issues must be considered in the management of adverse events? What side-effects may occur and how can they be recognised and treated? The present paper provides an overview of the new treatment options regarding their relevance as well as recommendations for their application in clinical practice. PMID- 29587322 TI - [The role of biomarkers in the diagnosis, prognosis and therapy of patients with immuno-oncological treatments of genito-urinary carcinomas]. AB - In recent years, fundamental research has yielded new insights into tumour biology, and new treatments have been developed. This review highlights the role of the pathologist and how he can support clinicians to find the right treatment for each patient. We explain the problems of the molecular subgroups of bladder cancer, the role of neo-adjuvant chemotherapy in the context of these findings, and show the important role of checkpoint inhibitors. Furthermore we focus on kidney cancer, with the clear cell carcinoma as the most frequent tumour type. We briefly consider prostate cancer, which as a hormone-dependent tumour probably requires different therapies. We also try to show the feasibility and the limits of pathology with the emerging tumour markers. PMID- 29587323 TI - [Immune checkpoint inhibition in metastatic urothelial carcinoma]. AB - The treatment of metastatic urothelial carcinoma is characterized by the administration of combinatory regimes of chemotherapy. In the first-line treatment theses regimes demonstrate relatively good objective response rates and prolongation of overall survival. The prognosis declines if the patient is refractory to platin in the second- or third-line treatment or if the patient is ineligible for cisplatin in the first-line setting. Cisplatin ineligibility is defined by a poor renal function or subsequent comorbidities. The new class of immune checkpoint inhibitors (ICI) has led to an impressive improvement in the therapy of mUC in platin-refractory or cisplatin-ineligible patients. Currently, the EMA has approved Atezolizumab, Nivolumab and Pembrolizumab based on phase II and III trial data. Future developments focus on first-line and adjuvant treatment of ICI with PD-L1/PD-1 as a backbone and in combination with either other ICI or chemotherapy. The prognostic use of biomarkers in ICI is still a medical need as the currently available results with regard to the PD-L1 status are heterogeneous. PMID- 29587324 TI - [Immunotherapy for renal cell carcinoma - current status]. AB - Systemic treatment of metastatic renal cell carcinoma (mRCC) has substantially changed during the last 2 years due to approval of the immune-checkpoint inhibitor Nivolumab (Opdivo(r)) and new multikinase inhibitors (Cabozantinib, Lenvatinib, Tivozanib). The german kidney tumor guideline strongly recommends Nivolumab and Cabozantinib as 2nd line treatments after prior VEGF targeted therapy. CheckMate 025, the prospective randomized trial which led to approval of Nivolumab demonstrated improved overall survival (26 month vs. 19.7 month; hazard ratio 0.73; p = 0.0006) and response rate (26 % vs. 5 %) as well as a favorable toxicity profile compared with Everolimus. Currently, numerous combinations with PD-1/PD-L1 inhibitors are compared to Sunitinib as first line treatment of mRCC. Out of these CheckMate 214, a randomized phase-3 trial is the first to demonstrate a significant higher objective response rate (42 % vs. 27 %, p < 0.0001) and overall survival (Sunitinib 26.0 month, median for Nivo + Ipi has been not yet reached (28.2 - NR); Hazard ratio 0.63) for the combination of Nivolumab and the CTLA-4 antibody Ipilimumab in IMDC intermediate and high risk patients. Furthermore, CheckMate 214 shows better side effect profile and quality of life in patients receiving Nivolumab and Ipilimumab compared with Sunitinib. However, a considerable increase of immune related adverse events is associated with the immune combination therapy. Another randomized trial demonstrates improved progression-free survival for the combination of the PD-L1 inhibitor Atezolizumab and the VEGF antibody Bevacizumab in patients with PD-L1 positive tumors; this was found in all IMDC risk groups. Further phase-3 trials with "new" VEGFR-TKIs (Axitinib, Cabozantinib, Lenvatinib) and PD-1/PD-L1 inhibitor combinations are ongoing.In conclusion, the PD-1 immune checkpoint inhibitor Nivolumab will remain a standard treatment for patients with metastatic renal cell carcinoma after prior VEGF targeted therapy. Nivolumab in combination with Ipilimumab will become a standard 1st line option for patients with intermediate and high risk profile according to IMDC. Further data are required regarding PD 1/PD-L1 inhibitors in combination with Bevacizumab and VEGFR-TKIs, respectively, including overall survival and side effect profile. PMID- 29587325 TI - ?

AB - BACKGROUND: Bronchiectasis is a chronic inflammatory disease characterised by a recurrent cycle of respiratory bacterial infections associated with cough, sputum production and impaired quality of life. Antibiotics are the main therapeutic option for managing bronchiectasis exacerbations. Evidence suggests that inhaled antibiotics may be associated with more effective eradication of infective organisms and a lower risk of developing antibiotic resistance when compared with orally administered antibiotics. However, it is currently unclear whether antibiotics are more effective when administered orally or by inhalation. OBJECTIVES: To determine the comparative efficacy and safety of oral versus inhaled antibiotics in the treatment of adults and children with bronchiectasis. SEARCH METHODS: We identified studies through searches of the Cochrane Airways Group's Specialised Register (CAGR), which is maintained by the Information Specialist for the group. The Register contains trial reports identified through systematic searches of bibliographic databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, AMED, and PsycINFO, and handsearching of respiratory journals and meeting abstracts. We also searched ClinicalTrials.gov and the WHO trials portal. We searched all databases in March 2018 and imposed no restrictions on language of publication. SELECTION CRITERIA: We planned to include studies which compared oral antibiotics with inhaled antibiotics. We would have considered short-term use (less than four weeks) for treating acute exacerbations separately from longer-term use as a prophylactic (4 weeks or more). We would have considered both intraclass and interclass comparisons. We planned to exclude studies if the participants received continuous or high-dose antibiotics immediately before the start of the trial, or if they have received a diagnosis of cystic fibrosis (CF), sarcoidosis, active allergic bronchopulmonary aspergillosis or active non-tuberculous Mycobacterial infection. DATA COLLECTION AND ANALYSIS: Two review authors independently applied study inclusion criteria to the searches and we planned for two authors to independently extract data, assess risk of bias and assess overall quality of the evidence using GRADE criteria. We also planned to obtain missing data from the authors where possible and to report results with 95% confidence intervals (CIs). MAIN RESULTS: We identified 313 unique records through database searches and a further 21 records from trial registers. We excluded 307 on the basis of title and abstract alone and a further 27 after examining full-text reports. No studies were identified for inclusion in the review. AUTHORS' CONCLUSIONS: There is currently no evidence indicating whether orally administered antibiotics are more beneficial compared to inhaled antibiotics. The recent ERS bronchiectasis guidelines provide a practical approach to the use of long-term antibiotics. New research is needed comparing inhaled versus oral antibiotic therapies for bronchiectasis patients with a history of frequent exacerbations, to establish which approach is the most effective in terms of exacerbation prevention, quality of life, treatment burden, and antibiotic resistance. PMID- 29587337 TI - Relationship between happiness and tobacco smoking among high school students. AB - OBJECTIVES: Recent research has described negative relationship between happiness and habitual smoking among adolescents. No study of this relationship has been conducted among Iranian adolescents. The aim of the present study was to characterize the relationship between happiness and cigarette or hookah smoking among a sample of high school students. METHODS: A sample of 1,161 10th-grade students in Tabriz (northwest Iran) was selected by multi-stage proportional cluster sampling. Participants completed a self-administered multiple-choice questionnaire including information on cigarette smoking, hookah smoking, happiness score, substance abuse, self-injury, general risk-taking behavior, attitudes towards smoking, socioeconomic information, and demographic characteristics. An ordinal logistic regression model was used for data analysis. RESULTS: It was found that 5.9 and 5.0% of students were regular cigarette smokers and regular hookah smokers, respectively. After controlling for potential confounders, higher happiness scores were found to protect students against more advanced stages of cigarette smoking (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99; p=0.013). However, no significant relationship was found between happiness scores and hookah smoking status (OR, 1.01; 95% CI, 0.97 to 1.02; p=0.523). CONCLUSIONS: Happiness scores were associated with less advanced stages of habitual cigarette smoking among high school students. Our findings underscore the necessity of conducting longitudinal or interventional studies aiming to determine the effects of enhancing happiness on preventing the transition through the stages of cigarette and hookah smoking. PMID- 29587338 TI - Interpretation of the hygiene and microflora hypothesis for allergic diseases through epigenetic epidemiology. AB - The hygiene hypothesis (HH) proposed by Strachan in 1989 was expanded to explain the inverse association between the occurrence of allergy disorders and the risk of infectious diseases and parasite infestation. The microflora hypothesis (MH) suggests that gut microbial dysbiosis in early life might trigger hypersensitivity disorders. The sharing concept of both HH and MH is gene environment interaction, which is also a key concept in epigenetics. The amalgamation of epidemiology and epigenetics has created a scientific discipline termed epigenetic epidemiology. To accomplish an era of gene-environment-wide interaction studies, it is necessary to launch a national human epigenome project. PMID- 29587339 TI - Gomisin G Inhibits the Growth of Triple-Negative Breast Cancer Cells by Suppressing AKT Phosphorylation and Decreasing Cyclin D1. AB - A type of breast cancer with a defect in three molecular markers such as the estrogen receptor, progesterone receptor, and human epidermal growth factor receptor is called triple-negative breast cancer (TNBC). Many patients with TNBC have a lower survival rate than patients with other types due to a poor prognosis. In this study, we confirmed the anti-cancer effect of a natural compound, Gomisin G, in TNBC cancer cells. Treatment with Gomisin G suppressed the viability of two TNBC cell lines, MDA-MB-231 and MDA-MB-468 but not non-TNBC cell lines such as MCF-7, T47D, and ZR75-1. To investigate the molecular mechanism of this activity, we examined the signal transduction pathways after treatment with Gomisin G in MDA-MB-231 cells. Gomisin G did not induce apoptosis but drastically inhibited AKT phosphorylation and reduced the amount of retinoblastoma tumor suppressor protein (Rb) and phosphorylated Rb. Gomisin G induced in a proteasome-dependent manner a decrease in Cyclin D1. Consequently, Gomisin G causes cell cycle arrest in the G1 phase. In contrast, there was no significant change in T47D cells except for a mild decrease in AKT phosphorylation. These results show that Gomisin G has an anti-cancer activity by suppressing proliferation rather than inducing apoptosis in TNBC cells. Our study suggests that Gomisin G could be used as a therapeutic agent in the treatment of TNBC patients. PMID- 29587340 TI - Genetic Variations Associated with Sleep Disorders in Patients with Schizophrenia: A Systematic Review. AB - Background: Schizophrenic patients commonly suffer from sleep disorders which are associated with acute disease severity, worsening prognoses and a poorer quality of life. Research is attempting to disentangle the complex interplay between schizophrenia and sleep disturbances by focusing not only on demographic and clinical characteristics, but also on the identification of genetic factors. Methods: Here, we performed a systematic literature review on the topic of genetic variations in sleep-disordered schizophrenic patients in an attempt to identify high quality investigations reporting scientifically sound and clinically useful data. For this purpose, we conducted a thorough search of PubMed, ScienceDirect and GoogleScholar databases, according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) protocol. Results: Our search yielded 11 eligible studies. Certain genetic variations were reported to be associated with schizophrenia-related sleep disorders. Antipsychotic-induced restless legs syndrome was linked to polymorphisms located on CLOCK, BTBD9, GNB3, and TH genes, clozapine-induced somnolence was correlated with polymorphisms of HNMT gene, while insomnia was associated with variants of the MTNR1 gene. Conclusions: There are significant genetic associations between schizophrenia and co-morbid sleep disorders, implicating the circadian system, dopamine and histamine metabolism and signal transduction pathways. PMID- 29587341 TI - Expression of Pinellia pedatisecta Lectin Gene in Transgenic Wheat Enhances Resistance to Wheat Aphids. AB - Wheat aphids are major pests during the seed filling stage of wheat. Plant lectins are toxic to sap-sucking pests such as wheat aphids. In this study, Pinellia pedatisecta agglutinin (ppa), a gene encoding mannose binding lectin, was cloned, and it shared 92.69% nucleotide similarity and 94% amino acid similarity with Pinellia ternata agglutinin (pta). The ppa gene, driven by the constitutive and phloem-specific ribulose bisphosphate carboxylase small subunit gene (rbcs) promoter in pBAC-rbcs-ppa expression vector, was transferred into the wheat cultivar Baofeng104 (BF104) by particle bombardment transformation. Fifty four T0 transgenic plants were generated. The inheritance and expression of the ppa gene were confirmed by PCR and RT-PCR analysis respectively, and seven homozygous transgenic lines were obtained. An aphid bioassay on detached leaf segments revealed that seven ppa transgenic wheat lines had lower aphid growth rates and higher inhibition rates than BF104. Furthermore, two-year aphid bioassays in isolated fields showed that aphid numbers per tiller of transgenic lines were significantly decreased, compared with wild type BF104. Therefore, ppa could be a strong biotechnological candidate to produce aphid-resistant wheat. PMID- 29587342 TI - Nutraceuticals for Skin Care: A Comprehensive Review of Human Clinical Studies. AB - The skin is the body's largest organ, it participates in sensitivity and offers protection against microorganisms, chemicals and ultraviolet (UV) radiation. Consequently, the skin may suffer alterations such as photo-ageing, immune dysfunction and inflammation which may significantly affect human health. Nutraceuticals represent a promising strategy for preventing, delaying, or minimising premature ageing of the skin and also to alleviate certain skin disorders. Among them, bioactive peptides and oligosaccharides, plant polyphenols, carotenoids, vitamins and polyunsaturated fatty acids are the most widely used ingredients. Supplementation with these products has shown evidence of having an effect on the signs of ageing and protection against UV radiation ageing in several human trials. In this review, the most relevant human studies on skin nutraceuticals are evaluated and the statistical resolution, biological relevance of their results, and, the trial protocols are discussed. In conclusion, quality and rigorousness of the trials must be improved to build credible scientific evidence for skin nutraceuticals and to establish a cause effect relationship between the ingredients the beneficial effects for the skin. PMID- 29587343 TI - Molecular Mechanisms of Melatonin Protection from Gastric Mucosal Apoptotic Injury in Experimental Burns. AB - Melatonin, a basic secretory pineal gland product, is a nontoxic, multifunctional molecule. It has antioxidant and anti-apoptotic activities and protects tissues from injury. The objective of the present study was to determine the molecular mechanism of melatonin anti-apoptotic effect on gastric injury in a rat burn model. We hypothesized that melatonin gastric protection may be related to the activation of transcription erythroid 2-related factor 2 (Nrf2). Using a 30% total body surface area (TBSA) rat burn model, melatonin (10 mg/kg, i.p.) was injected immediately and 12 h after thermal skin injury. Via light immunohistochemistry, we determined the tissue level of 4-hydroxy-2-nonenal (4 HNE) as a marker of lipid peroxidation, Bcl-2 and Bax as apoptosis-related proteins, and Nrf2. Results are presented as medians (interquartile range (IQR)). Thermal trauma in burned animals, compared with the controls, increased the expression of pro-apoptotic Bax protein (1.37 (0.94-1.47)), decreased anti apoptotic Bcl-2 protein (1.16 (1.06-1.23), p < 0.001) in epithelial cells, and elevated Bax/Bcl-2 ratios (p < 0.05). Tissue 4-HNE and Nrf2 levels were increased following severe burns (1.55 (0.98-1.61) and 1.16 (1.01-1.25), p < 0.05, respectively). Melatonin significantly decreased 4-HNE (0.87 (0.74-0.96), p < 0.01) and upregulated Nrf2 (1.55 (1.52-1.65), p < 0.001) levels. It also augmented Bax (1.68 (1.5-1.8), p < 0.001) and Bcl-2 expressions (1.96 (1.89 2.01), p < 0.0001), but reduced Bax/Bcl-2 ratios (p < 0.05). Our results suggest that experimental thermal trauma induces oxidative gastric mucosal injury. Melatonin manifests a gastroprotective effect through Nrf2 activation, lipid peroxidation attenuation, and Bax/Bcl-2 ratio modification as well. PMID- 29587344 TI - Economy of Catalyst Synthesis-Convenient Access to Libraries of Di- and Tetranaphtho Azepinium Compounds. AB - Efficient optimization procedures in chiral catalysis are usually linked to a straightforward strategy to access groups of structurally similar catalysts required for fine-tuning. The ease of building up such ligand libraries can be increased when the structure-modifying step (introduction of a substituent) is done at a later stage of the synthesis. This is demonstrated for the extended family of di- and tetranaphtho azepinium compounds, widely used as chiral phase transfer catalysts (PTC). Using 2,6-diiodo-4,5-dihydro-3H-dinaphtho[2,1-c:1',2' e]azepine and 4,8-diiodo-6,7-dihydro-5H-dibenzo[c,e]azepine, respectively, as key intermediates, 18 spiro-azepinium compounds were synthesized in a total yield of 25-42% over 6-7 steps from 1,1'-binaphthyl-2,2'-dicarboxylic acid or diphenic acid, respectively. The replacement of iodo groups with aryl substituents was performed as the last or the penultimate step of the synthesis. PMID- 29587345 TI - Multifunctional Fischer Aminocarbene Complexes as Hole or Electron Transporting Layers in Organic Solar Cells. AB - A new series of Fischer carbenes have been synthetized and examined as hole transporting or electron-transporting layers (HTLs or ETLs) in the fabrication of organic solar cells (OSCs). The synthesis of three Fischer aminocarbene complexes with the general formula [Cr(CO)5{C(NHCH2)Ar}] (Ar = 2-pyridyl (3a), 3-pyridyl (3b) and 4-pyridyl (3c)) is reported. The molecular structure of complex 3b has been confirmed by X-ray analysis. In order to study the possible applications of the three Fischer aminocarbenes in OSCs, thin films of these complexes were prepared using a vacuum deposition process. These organometallic films were chemically and morphologically characterized by IR spectroscopy, SEM, AFM and XRD. According to the IR and Tauc analysis, the vacuum deposition process generates thin films free of impurities with an activation energy of 4.0, 2.7 and 2.1 eV for 3a, 3b y 3c, respectively. The UV-vis spectra of the amorphous aminocarbene films show that they are practically transparent to the visible radiation of the electromagnetic spectrum. This is due to the fact that their absorption is located mainly in the ultraviolet range. Two OSCs with bulk heterojunction configuration were manufactured in order to prove the use of the aminocarbenes as ETL o HTL. The aminocarbene [Cr(CO)5{C(NHCH2) 4-pyridyl}] (3c) proved to be suitable as ETL with a fill factor (FF) of 0.23 and a short circuit current density (JSC) of 1.037 mA/cm2.

AB - The spatiotemporal characteristics and human health risks of 12 heavy metals (Al, As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sb, Se, and Tl) in fine particulate matter (PM2.5) in Zhejiang Province were investigated. The annual average PM2.5 concentration was 58.83 ug/m3 in 2015 in Zhejiang. Element contents in PM2.5 varied greatly with the season and locations. Al, Pb, and Mn were the most abundant elements among the studied metal(loid)s in PM2.5. The non-carcinogenic risks of the 12 elements through inhalation and dermal contact exposure were lower than the safe level for children and adults. However, there were potential non-carcinogenic risks of Tl, As, and Sb for children and Tl for adults through ingestion exposure. The carcinogenic risks from As, Be, Cd, Cr, Pb, and Ni through inhalation exposure were less than the acceptable level (1 * 10-4) for children and adults. Pb may carry a potential carcinogenic risk for both children and adults through ingestion. More attention should be paid to alleviate non carcinogenic and carcinogenic health risks posed by particle-bound toxic elements through ingestion exposure. PMID- 29587348 TI - Rhamnellosides A and B, omega-Phenylpentaene Fatty Acid Amide Diglycosides from the Fruits of Rhamnella franguloides. AB - Two new omega-phenylpentaene fatty acid amide diglycosides, rhamnellosides A (1) and B (2), were isolated from the fruits of Rhamnella franguloides (Rhamnaceae). These compounds were prioritized using LC-MS/MS molecular networking dereplication based on our previous discovery of 2-acetoxy-omega-phenylpentaene fatty acid triglycosides berchemiosides A-C from a phylogenetically related species, Berchemia berchemiifolia. The structures of the isolated compounds were elucidated by spectroscopic analyses in combination with chemical derivatization. The pentaene groups of 1 and 2 were found to have (6E, 8E, 10Z, 12Z, 14E) geometry, which is the same as that found in berchemioside A.

AB - Survivin, an anti-apoptotic molecule abundantly expressed in most human neoplasms, has been reported to contribute to cancer initiation and drug resistance in a wide variety of human tumors. Efficient downregulation of survivin can sensitize tumor cells to various therapeutic interventions, generating considerable efforts in its validation as a new target in cancer therapy. This review thoroughly analyzes up-to-date information on the potential of survivin as a therapeutic target for new anticancer treatments. The literature dealing with the therapeutic targeting of survivin will be reviewed, discussing specifically squamous cell carcinomas (SCCs), and with emphasis on the last clinical trials. This review gives insight into the recent developments undertaken in validating various treatment strategies that target survivin in SCCs and analyze the translational possibility, identifying those strategies that seem to be the closest to being incorporated into clinical practice. The most recent developments, such as dominant-negative survivin mutants, RNA interference, anti-sense oligonucleotides, small-molecule inhibitors, and peptide based immunotherapy, seem to be helpful for effectively downregulating survivin expression and reducing tumor growth potential, increasing the apoptotic rate, and sensitizing tumor cells to chemo- and radiotherapy. However, selective and efficient targeting of survivin in clinical trials still poses a major challenge. PMID- 29587349 TI - Evaluation of Two Liver Treatment Strategies in a Mouse Model of Niemann-Pick Disease Type C1. AB - Niemann-Pick-disease type C1 (NPC1) is an autosomal-recessive cholesterol-storage disorder. Besides other symptoms, NPC1 patients develop liver dysfunction and hepatosplenomegaly. The mechanisms of hepatomegaly and alterations of lipid metabolism-related genes in NPC1 disease are still poorly understood. Here, we used an NPC1 mouse model to study an additive hepatoprotective effect of a combination of 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD), miglustat and allopregnanolone (combination therapy) with the previously established monotherapy using HPbetaCD. We examined transgene effects as well as treatment effects on liver morphology and hepatic lipid metabolism, focusing on hepatic cholesterol transporter genes. Livers of Npc1-/- mice showed hepatic cholesterol sequestration with consecutive liver injury, an increase of lipogenetic gene expression, e.g., HMG-CoA, a decrease of lipolytic gene expression, e.g., pparalpha and acox1, and a decrease of lipid transporter gene expression, e.g., acat1, abca1 and fatp2. Both, combination therapy and monotherapy, led to a reduction of hepatic lipids and an amelioration of NPC1 liver disease symptoms. Monotherapy effects were related to pparalpha- and acox1-associated lipolysis/beta-oxidation and to fatp2-induced fatty acid transport, whereas the combination therapy additionally increased the cholesterol transport via abca1 and apoE. However, HPbetaCD monotherapy additionally increased cholesterol synthesis as indicated by a marked increase of the HMG-CoA and srebp-2 mRNA expression, probably as a result of increased hepatocellular proliferation. PMID- 29587350 TI - Polymeric Nanoparticles for Increasing Oral Bioavailability of Curcumin. AB - Despite the promising biological and antioxidant properties of curcumin, its medical applications are limited due to poor solubility in water and low bioavailability. Polymeric nanoparticles (NPs) adapted to oral delivery may overcome these drawbacks. Properties such as particle size, zeta potential, morphology and encapsulation efficiency were assessed. Then, the possibility of storing these NPs in a solid-state form obtained by freeze-drying, in vitro curcumin dissolution and cytocompatibility towards intestinal cells were evaluated. Curcumin-loaded Eudragit(r) RLPO (ERL) NPs showed smaller particle diameters (245 +/- 2 nm) and better redispersibility after freeze-drying than either poly(lactic-co-glycolic acid) (PLGA) or polycaprolactone (PCL) NPs. The former NPs showed lower curcumin encapsulation efficiency (62%) than either PLGA or PCL NPs (90% and 99%, respectively). Nevertheless, ERL NPs showed rapid curcumin release with 91 +/- 5% released over 1 h. The three curcumin-loaded NPs proposed in this work were also compatible with intestinal cells. Overall, ERL NPs are the most promising vehicles for increasing the oral bioavailability of curcumin. PMID- 29587351 TI - Physicochemical Characterization and Antioxidant Activity of Humic Acids Isolated from Peat of Various Origins. AB - Although humic acids (HAs) from peat exhibit various therapeutic properties, there is little information available concerning their physicochemical and antioxidant properties. To address this issue, nine different types of peat, including oligotrophic, mesotrophic, and minerotrophic peat samples, were used for isolation of HA fractions by basic (HAb) and pyrophosphate (HAp) extractions. Physical parameters of the HAs were analyzed by UV-Vis, fluorescent, infrared (IR), and electron paramagnetic resonance (EPR) spectroscopy. Average Mr of the fractions ranged from 17.2 to 39.7 kDa, while their humification index (HIX) varied from 0.49 to 1.21. HAp fractions had a higher content of aromatic structures compared to HAb fractions. Moreover, HAp fractions had a significantly higher content of phenolic OH groups (3.6 +/- 0.5 mmol/g) versus HAb (3.1 +/- 0.5 mmol/g). All HA fractions exhibited antioxidant activity in radical scavenging and electrochemical assays, and their EPR signal had a single line with g = 2.0035, which is consistent with semiquinone type radicals. Furthermore, the HIX was found to be important in determining the number of semiquinone-type free radicals in the HA structures. Overall, these data provide a molecular basis to explain at least part of the beneficial therapeutic properties of peat-derived HAs. PMID- 29587353 TI - Implementation of a Medication Reconciliation Process in an Internal Medicine Clinic at an Academic Medical Center. AB - Discrepancies in medication orders at transitions of care have been shown to affect patient outcomes in a negative way. The Joint Commission recognizes the importance of medication reconciliation through their National Patient Safety Goals, with an emphasis placed on maintaining accurate medication information for each patient. The primary objective of this study was to assess the effectiveness of implementing a medication reconciliation process in an internal medicine clinic at an academic medical center. A retrospective chart review of patients seen at an Internal Medicine Clinic within and Academic Medical Center, a continuity and teaching clinic for Internal Medicine residents and faculty practice clinic, was conducted. Nursing staff were educated by PharmDs to perform a standardized medication history during the triage process. Medication reconciliation data was analyzed for 3263 patients from 1 August 2014 to 27 February 2015. A total of 4479 discrepancies were found through this process, with the majority (71%) of discrepancies being medications on the list that patient was no longer taking. This project illustrated to our nursing and physician staff the need for regular thorough review of the patient medication list. PMID- 29587352 TI - MFAM: Multiple Frequency Adaptive Model-Based Indoor Localization Method. AB - This paper presents MFAM (Multiple Frequency Adaptive Model-based localization method), a novel model-based indoor localization method that is capable of using multiple wireless signal frequencies simultaneously. It utilizes indoor architectural model and physical properties of wireless signal propagation through objects and space. The motivation for developing multiple frequency localization method lies in the future Wi-Fi standards (e.g., 802.11ah) and the growing number of various wireless signals present in the buildings (e.g., Wi-Fi, Bluetooth, ZigBee, etc.). Current indoor localization methods mostly rely on a single wireless signal type and often require many devices to achieve the necessary accuracy. MFAM utilizes multiple wireless signal types and improves the localization accuracy over the usage of a single frequency. It continuously monitors signal propagation through space and adapts the model according to the changes indoors. Using multiple signal sources lowers the required number of access points for a specific signal type while utilizing signals, already present in the indoors. Due to the unavailability of the 802.11ah hardware, we have evaluated proposed method with similar signals; we have used 2.4 GHz Wi-Fi and 868 MHz HomeMatic home automation signals. We have performed the evaluation in a modern two-bedroom apartment and measured mean localization error 2.0 to 2.3 m and median error of 2.0 to 2.2 m. Based on our evaluation results, using two different signals improves the localization accuracy by 18% in comparison to 2.4 GHz Wi-Fi-only approach. Additional signals would improve the accuracy even further. We have shown that MFAM provides better accuracy than competing methods, while having several advantages for real-world usage. PMID- 29587354 TI - Folinic Acid Increases Protein Arginine Methylation in Human Endothelial Cells. AB - Elevated plasma total homocysteine (tHcy) is associated with increased risk of cardiovascular disease, but the mechanisms underlying this association are not completely understood. Cellular hypomethylation has been suggested to be a key pathophysiologic mechanism, since S-adenosylhomocysteine (AdoHcy), the Hcy metabolic precursor and a potent inhibitor of methyltransferase activity, accumulates in the setting of hyperhomocysteinemia. In this study, the impact of folate and methionine on intracellular AdoHcy levels and protein arginine methylation status was studied. Human endothelial cells were incubated with increasing concentrations of folinic acid (FnA), a stable precursor of folate, with or without methionine restriction. The levels of intracellular AdoHcy and AdoMet, tHcy in the cell culture medium, and protein-incorporated methylarginines were evaluated by suitable liquid chromatography techniques. FnA supplementation, with or without methionine restriction, reduced the level of tHcy and did not affect intracellular AdoMet levels. Interestingly, FnA supplementation reduced intracellular AdoHcy levels only in cells grown under methionine restriction. Furthermore, these cells also displayed increased protein arginine methylation status. These observations suggest that folic acid supplementation may enhance cellular methylation capacity under a low methionine status. Our results lead us to hypothesize that the putative benefits of folic acid supplementation in restoring endothelial homeostasis, thus preventing atherothrombotic events, should be reevaluated in subjects under a methionine restriction diet. PMID- 29587356 TI - Dietary Patterns and Their Relationship with Frailty in Functionally Independent Older Adults. AB - The impact of dietary patterns rather than single foods or nutrients on health outcomes is increasingly recognized. This cross-sectional study examines the dietary patterns of 527 non-institutionalized functionally independent older people aged >=70 years from Gipuzkoa (Spain). Sociodemographic characteristics, health status, anthropometric measures and dietary data are collected. Multiple correspondence analysis (MCA) and cluster analysis are performed to identify dietary patterns and groups of individuals. Frequency of selected food items and compliance with food recommendations are included in the MCA. A high proportion of the sample population are overweight or obese, whereas only 3.3% are at risk of malnutrition (determined with the Mini Nutritional Assessment). Frail individuals (n = 130), measured with the Timed-Up and Go test are older, have a lower educational level, are more obese, present a poorer health status (more depressive symptoms, polypharmacy and falls, among others) and worse compliance with food recommendations than robust individuals (n = 392). Three groups of individuals are identified: cluster one (n = 285), cluster two (n = 194) and cluster three (n = 48). A gradient of increasing frailty and poorer health status is observed from cluster one to cluster three. The latter also shows the poorest dietary pattern, regarding dietary recommendations. The use of an easy-to-use tool to assess diet allows detection of differences among the three clusters. There is a need to increase awareness on the implementation of nutritional screening and a subsequent dietary assessment in primary care settings to provide nutritional care to elder, and moreover, frail individuals. PMID- 29587357 TI - Importance of Footwear for Preventing Xerosis and Hyperkeratosis in Older People with Psychiatric Disorders Living in an Institution. AB - Few studies have focused on the relation between the use and characteristics of footwear and the presence of foot lesions in people with psychiatric disorders. This work analyzes the influence of different footwear habits on the presence of deformities and ungueal and dermal pathologies of the foot of institutionalized people with psychiatric disorders compared to people without these disorders. A transversal and observational study was conducted on 107 participants, divided into two groups who have used different types of shoes throughout their lives. The control group comprised 63 autonomous people who mainly use leather footwear and a study group of 44 institutionalized people with intellectual disabilities and psychiatric disorders who mainly use textile footwear. There were significant differences between populations. The group with psychiatric disorders presented more xerosis and hyperkeratosis. Footwear with inappropriate characteristics is a possible causal agent of skin alterations. Wearing footwear with quality textile uppers, e.g., fabric or felt, could influence the appearance of these alterations. Leather footwear is recommended for institutionalized people to reduce symptoms of xerosis and improve their quality of life. PMID- 29587355 TI - Rationale for Dietary Antioxidant Treatment of ADHD. AB - Increasing understanding arises regarding disadvantages of stimulant medication in children with ADHD (Attention-Deficit Hyperactivity Disorder). This review presents scientific findings supporting dietary antioxidant treatment of ADHD and describes substantial alterations in the immune system, epigenetic regulation of gene expression, and oxidative stress regulation in ADHD. As a result, chronic inflammation and oxidative stress could develop, which can lead to ADHD symptoms, for example by chronic T-cell-mediated neuroinflammation, as well as by neuronal oxidative damage and loss of normal cerebral functions. Therefore, modulation of immune system activity and oxidant-antioxidant balance using nutritional approaches might have potential in ADHD treatment. The use of natural antioxidants against oxidative conditions is an emerging field in the management of neurodegenerative diseases. Dietary polyphenols, for example, have antioxidant capacities as well as immunoregulatory effects and, therefore, appear appropriate in ADHD therapy. This review can stimulate the development and investigation of dietary antioxidant treatment in ADHD, which is highly desired. PMID- 29587358 TI - Surface Texture-Based Surface Treatments on Ti6Al4V Titanium Alloys for Tribological and Biological Applications: A Mini Review. AB - Surface texture (ST) has been confirmed as an effective and economical surface treatment technique that can be applied to a great range of materials and presents growing interests in various engineering fields. Ti6Al4V which is the most frequently and successfully used titanium alloy has long been restricted in tribological-related operations due to the shortcomings of low surface hardness, high friction coefficient, and poor abrasive wear resistance. Ti6Al4V has benefited from surface texture-based surface treatments over the last decade. This review begins with a brief introduction, analysis approaches, and processing methods of surface texture. The specific applications of the surface texture based surface treatments for improving surface performance of Ti6Al4V are thoroughly reviewed from the point of view of tribology and biology. PMID- 29587360 TI - Photocatalytic Activity of Nanotubular TiO2 Films Obtained by Anodic Oxidation: A Comparison in Gas and Liquid Phase. AB - The availability of immobilized nanostructured photocatalysts is of great importance in the purification of both polluted air and liquids (e.g., industrial wastewaters). Metal-supported titanium dioxide films with nanotubular morphology and good photocatalytic efficiency in both environments can be produced by anodic oxidation, which avoids release of nanoscale materials in the environment. Here we evaluate the effect of different anodizing procedures on the photocatalytic activity of TiO2 nanostructures in gas and liquid phases, in order to identify the most efficient and robust technique for the production of TiO2 layers with different morphologies and high photocatalytic activity in both phases. Rhodamine B and toluene were used as model pollutants in the two media, respectively. It was found that the role of the anodizing electrolyte is particularly crucial, as it provides substantial differences in the oxide specific surface area: nanotubular structures show remarkably different activities, especially in gas phase degradation reactions, and within nanotubular structures, those produced by organic electrolytes lead to better photocatalytic activity in both conditions tested. PMID- 29587359 TI - Down Syndrome, Obesity, Alzheimer's Disease, and Cancer: A Brief Review and Hypothesis. AB - Down syndrome (trisomy 21), a complex mix of physical, mental, and biochemical issues, includes an increased risk of Alzheimer's disease and childhood leukemia, a decreased risk of other tumors, and a high frequency of overweight/obesity. Certain features related to the third copy of chromosome 21 (which carries the APP gene and several anti-angiogenesis genes) create an environment favorable for Alzheimer's disease and unfavorable for cancer. This environment may be enhanced by two bioactive compounds from fat cells, leptin, and adiponectin. This paper outlines these fat-related disease mechanisms and suggests new avenues of research to reduce disease risk in Down syndrome. PMID- 29587361 TI - Endophytic Mycoflora and Their Bioactive Compounds from Azadirachta Indica: A Comprehensive Review. AB - Plants are all inhabited by endophytic fungi in the interior of their tissues. The neem tree Azadirachta is an Indian lilac used for various therapeutic purposes in different forms of preparations. This plant hosts different types of endophytic fungi. In some cases, different tissues of a given plant are inhabited by different endophytic fungi which are discussed in this paper. Recently, there have been new reports on endophytic fungi and their bioactive compounds from Azadirachta indica. The biological function of bioactive compounds was discussed in view of their future industrial prospects. There are a number of different research investigations that examine the endophytes isolated and screened for their potential bioactive secondary metabolites from neem, but there is no comprehensive review on neem endophytes and their secondary metabolites to bring all trends from different researchers together. Therefore, in this review, we have discussed the endophytic fungi from the different tissues of neem, in view of the latest understandings of antimicrobial, antioxidant, and pathogenicity target compounds. Importantly, tracing the previous findings would pave the way to forecast the missing link for future work by researchers. PMID- 29587362 TI - OTA Prevention and Detoxification by Actinobacterial Strains and Activated Carbon Fibers: Preliminary Results. AB - Ochratoxin A (OTA) is a mycotoxin produced by several species of Aspergillus and Penicillium that contaminate food and feed raw materials. To reduce OTA contamination, we first tested in vitro, actinobacterial strains as potential biocontrol agents and afterward, through a physical decontamination method using activated carbon fibers (ACFs). Actinobacterial strains were screened for their ability to reduce OTA in solid co-culture with A. carbonarius, which is the major OTA-producing species in European vineyards. Four strains showed a high affinity for removing OTA (67%-83%) with no significant effect on fungal growth (<20%). The mechanism of action was first studied by analyzing the expression of OTA cluster genes (acOTApks, acOTAnrps, acOTAhal) by RT-qPCR showing a drastic reduction in all genes (7-15 times). Second, the ability of these strains to degrade OTA was assessed in vitro on ISP2 solid medium supplemented with OTA (100 ug/L). Two strains reduced OTA to undetectable levels. As for the physical method, high adsorption rates were obtained for ACFs at 0.8 g/L with a 50% adsorption of OTA in red wine by AC15 and 52% in grape juice by AC20 within 24 h. These promising methods could be complementarily applied toward reducing OTA contamination in food chains, which promotes food safety and quality. PMID- 29587363 TI - Human-Like Neutralizing Antibodies Protect Mice from Aerosol Exposure with Western Equine Encephalitis Virus. AB - Western equine encephalitis virus (WEEV) causes symptoms in humans ranging from mild febrile illness to life-threatening encephalitis, and no human medical countermeasures are licensed. A previous study demonstrated that immune serum from vaccinated mice protected against lethal WEEV infection, suggesting the utility of antibodies for pre- and post-exposure treatment. Here, three neutralizing and one binding human-like monoclonal antibodies were evaluated against WEEV aerosol challenge. Dose-dependent protection was observed with two antibodies administered individually, ToR69-3A2 and ToR68-2C3. In vitro neutralization was not a critical factor for protection in this murine model, as ToR69-3A2 is a strong neutralizing antibody, and ToR68-2C3 is a non-neutralizing antibody. This result highlights the importance of both neutralizing and non neutralizing antibodies in the protection of mice from WEEV lethality. PMID- 29587364 TI - Baicalein Rescues Delayed Cooling via Preservation of Akt Activation and Akt Mediated Phospholamban Phosphorylation. AB - Cooling reduces the ischemia/reperfusion (I/R) injury seen in sudden cardiac arrest (SCA) by decreasing the burst of reactive oxygen species (ROS). Its cardioprotection is diminished when delay in reaching the target temperature occurs. Baicalein, a flavonoid derived from the root of ScutellariabaicalensisGeorgi, possesses antioxidant properties. Therefore, we hypothesized that baicalein can rescue cooling cardioprotection when cooling is delayed. Two murine cardiomyocyte models, an I/R model (90 min ischemia/3 h reperfusion) and stunning model (30 min ischemia/90 min reperfusion), were used to assess cell survival and contractility, respectively. Cooling (32 degrees C) was initiated either during ischemia or during reperfusion. Cell viability and ROS generation were measured. Cell contractility was evaluated by real-time phase contrast imaging. Our results showed that cooling reduced cell death and ROS generation, and this effect was diminished when cooling was delayed. Baicalein (25 uM), given either at the start of reperfusion or start of cooling, resulted in a comparable reduction of cell death and ROS production. Baicalein improved phospholamban phosphorylation, contractility recovery, and cell survival. These effects were Akt-dependent. In addition, no synergistic effect was observed with the combined treatments of cooling and baicalein. Our data suggest that baicalein may serve as a novel adjunct therapeutic strategy for SCA resuscitation. PMID- 29587365 TI - Green, Hydrothermal Synthesis of Fluorescent Carbon Nanodots from Gardenia, Enabling the Detection of Metronidazole in Pharmaceuticals and Rabbit Plasma. AB - Strong fluorescent carbon nanodots (FCNs) were synthesized with a green approach using gardenia as a carbon source through a one-step hydrothermal method. FCNs were characterized by their UV-vis absorption spectra, photoluminescence (PL), Fourier transform infrared spectroscopy (FTIR) as well as X-ray photoelectron spectroscopy (XPS). We further explored the use of as-synthesized FCNs as an effective probe for the detection of metronidazole (MNZ), which is based on MNZ induced fluorescence quenching of FCNs. The proposed method displayed a wide linear range from 0.8 to 225.0 uM with a correlation coefficient of 0.9992 and a limit of detection as low as 279 nM. It was successfully applied to the determination of MNZ in commercial tablets and rabbit plasma with excellent sensitivity and selectivity, which indicates its potential applications in clinical analysis and biologically related studies. PMID- 29587366 TI - Efficient Proximity Computation Techniques Using ZIP Code Data for Smart Cities ?. AB - In this paper, we are interested in computing ZIP code proximity from two perspectives, proximity between two ZIP codes (Ad-Hoc) and neighborhood proximity (Top-K). Such a computation can be used for ZIP code-based target marketing as one of the smart city applications. A naive approach to this computation is the usage of the distance between ZIP codes. We redefine a distance metric combining the centroid distance with the intersecting road network between ZIP codes by using a weighted sum method. Furthermore, we prove that the results of our combined approach conform to the characteristics of distance measurement. We have proposed a general and heuristic approach for computing Ad-Hoc proximity, while for computing Top-K proximity, we have proposed a general approach only. Our experimental results indicate that our approaches are verifiable and effective in reducing the execution time and search space. PMID- 29587368 TI - Efficacy of Praziquantel in the Treatment of Platynosomum fastosum in Cats with Natural Infections. AB - Treatments for Platynosomum fastosum-the liver fluke of cats-have been developed based on fecal egg counts. Post mortem fluke counts are required to understand true efficacy. In this study, two praziquantel treatment regimens were evaluated using post mortem fluke counts: a high-dose treatment (HT) of 20 mg/kg body weight (BW) administered intramuscularly (IM) once a day for three consecutive days and a low-dose treatment (LT) of 5 mg/kg BW administered once (IM) and repeated 14 days later. A continual enrolment study design was used with 16 naturally infected cats randomly allocated in blocks of four to the HT (eight cats) or LT (eight cats) group. Treatment success, defined as absence of live flukes post mortem, was determined 10 days after the last treatment. Pre- and post-treatment fecal egg counts (centrifugation with Sheather's sugar flotation solution) and bile egg counts (obtained via percutaneous ultrasound guided cholecystocentesis) were evaluated as supportive efficacy data. Twelve cats completed the study with two cats withdrawn from each group. Neither treatment was 100% effective. In the HT group, three of six cats had live flukes, albeit low numbers, at post mortem, while all six LT group cats had live flukes. While fecal and bile egg counts were reduced in both group, they were not reflective of the true infection status of the cats post mortem. PMID- 29587369 TI - An SCFFBXO28 E3 Ligase Protects Pancreatic beta-Cells from Apoptosis. AB - Loss of pancreatic beta-cell function and/or mass is a central hallmark of all forms of diabetes but its molecular basis is incompletely understood. beta-cell apoptosis contributes to the reduced beta-cell mass in diabetes. Therefore, the identification of important signaling molecules that promote beta-cell survival in diabetes could lead to a promising therapeutic intervention to block beta-cell decline during development and progression of diabetes. In the present study, we identified F-box protein 28 (FBXO28), a substrate-recruiting component of the Skp1-Cul1-F-box (SCF) ligase complex, as a regulator of pancreatic beta-cell survival. FBXO28 was down-regulated in beta-cells and in isolated human islets under diabetic conditions. Consistently, genetic silencing of FBXO28 impaired beta-cell survival, and restoration of FBXO28 protected beta-cells from the harmful effects of the diabetic milieu. Although FBXO28 expression positively correlated with beta-cell transcription factor NEUROD1 and FBXO28 depletion also reduced insulin mRNA expression, neither FBXO28 overexpression nor depletion had any significant impact on insulin content, glucose-stimulated insulin secretion (GSIS) or on other genes involved in glucose sensing and metabolism or on important beta-cell transcription factors in isolated human islets. Consistently, FBXO28 overexpression did not further alter insulin content and GSIS in freshly isolated islets from patients with type 2 diabetes (T2D). Our data show that FBXO28 improves pancreatic beta-cell survival under diabetogenic conditions without affecting insulin secretion, and its restoration may be a novel therapeutic tool to promote beta-cell survival in diabetes. PMID- 29587367 TI - Mammalian Plakins, Giant Cytolinkers: Versatile Biological Functions and Roles in Cancer. AB - Cancer is a highly lethal disease that is characterized by aberrant cell proliferation, migration, and adhesion, which are closely related to the dynamic changes of cytoskeletons and cytoskeletal-adhesion. These will further result in cell invasion and metastasis. Plakins are a family of giant cytolinkers that connect cytoskeletal elements with each other and to junctional complexes. With various isoforms composed of different domain structures, mammalian plakins are broadly expressed in numerous tissues. They play critical roles in many cellular processes, including cell proliferation, migration, adhesion, and signaling transduction. As these cellular processes are key steps in cancer development, mammalian plakins have in recent years attracted more and more attention for their potential roles in cancer. Current evidence shows the importance of mammalian plakins in various human cancers and demonstrates mammalian plakins as potential biomarkers for cancer. Here, we introduce the basic characteristics of mammalian plakins, review the recent advances in understanding their biological functions, and highlight their roles in human cancers, based on studies performed by us and others. This will provide researchers with a comprehensive understanding of mammalian plakins, new insights into the development of cancer, and novel targets for cancer diagnosis and therapy. PMID- 29587370 TI - Stakeholders' Perceptions of Agronomic Iodine Biofortification: A SWOT-AHP Analysis in Northern Uganda. AB - Agronomic biofortification (i.e., the application of fertilizer to elevate micronutrient concentrations in staple crops) is a recent strategy recommended for controlling Iodine Deficiency Disorders (IDDs). However, its success inevitably depends on stakeholders' appreciation and acceptance of it. By taking Northern Uganda as a case, this study aimed to capture and compare the perceptions of seven key stakeholder groups with respect to agronomic iodine biofortification. Therefore, we employed a SWOT (Strength, Weaknesses, Opportunities & Threats) analysis in combination with an Analytical Hierarchy Process (AHP). Findings show that stakeholders (n = 56) are generally positive about agronomic iodine biofortification in Uganda, as its strengths and opportunities outweighed weaknesses and threats. Cultural acceptance and effectiveness are considered the most important strengths while the high IDD prevalence rate and the availability of iodine deficient soils are key opportunities for further developing agronomic iodine biofortification. Environmental concerns about synthetic fertilizers as well as the time needed to supply iodine were considered crucial weaknesses. The limited use of fertilizer in Uganda was the main threat. While this study provides insight into important issues and priorities for iodine biofortification technology in Uganda, including differences in stakeholder views, the application of the SWOT-AHP method will guide future researchers and health planners conducting stakeholder analysis in similar domains. PMID- 29587371 TI - Building Change Detection from Bi-Temporal Dense-Matching Point Clouds and Aerial Images. AB - In this work, a novel building change detection method from bi-temporal dense matching point clouds and aerial images is proposed to address two major problems, namely, the robust acquisition of the changed objects above ground and the automatic classification of changed objects into buildings or non-buildings. For the acquisition of changed objects above ground, the change detection problem is converted into a binary classification, in which the changed area above ground is regarded as the foreground and the other area as the background. For the gridded points of each period, the graph cuts algorithm is adopted to classify the points into foreground and background, followed by the region-growing algorithm to form candidate changed building objects. A novel structural feature that was extracted from aerial images is constructed to classify the candidate changed building objects into buildings and non-buildings. The changed building objects are further classified as "newly built", "taller", "demolished", and "lower" by combining the classification and the digital surface models of two periods. Finally, three typical areas from a large dataset are used to validate the proposed method. Numerous experiments demonstrate the effectiveness of the proposed algorithm. PMID- 29587372 TI - Optimize the Coverage Probability of Prediction Interval for Anomaly Detection of Sensor-Based Monitoring Series. AB - Effective anomaly detection of sensing data is essential for identifying potential system failures. Because they require no prior knowledge or accumulated labels, and provide uncertainty presentation, the probability prediction methods (e.g., Gaussian process regression (GPR) and relevance vector machine (RVM)) are especially adaptable to perform anomaly detection for sensing series. Generally, one key parameter of prediction models is coverage probability (CP), which controls the judging threshold of the testing sample and is generally set to a default value (e.g., 90% or 95%). There are few criteria to determine the optimal CP for anomaly detection. Therefore, this paper designs a graphic indicator of the receiver operating characteristic curve of prediction interval (ROC-PI) based on the definition of the ROC curve which can depict the trade-off between the PI width and PI coverage probability across a series of cut-off points. Furthermore, the Youden index is modified to assess the performance of different CPs, by the minimization of which the optimal CP is derived by the simulated annealing (SA) algorithm. Experiments conducted on two simulation datasets demonstrate the validity of the proposed method. Especially, an actual case study on sensing series from an on-orbit satellite illustrates its significant performance in practical application.

AB - In this paper, we compare six known linear distributed average consensus algorithms on a sensor network in terms of convergence time (and therefore, in terms of the number of transmissions required). The selected network topologies for the analysis (comparison) are the cycle and the path. Specifically, in the present paper, we compute closed-form expressions for the convergence time of four known deterministic algorithms and closed-form bounds for the convergence time of two known randomized algorithms on cycles and paths. Moreover, we also compute a closed-form expression for the convergence time of the fastest deterministic algorithm considered on grids.

AB - The increasing environmental pollution with particular reference to emerging contaminants, toxic heavy elements, and other hazardous agents is a serious concern worldwide. Considering this global issue, there is an urgent need to design and develop strategic measuring techniques with higher efficacy and precision to detect a broader spectrum of numerous contaminants. The development of precise instruments can further help in real-time and in-process monitoring of the generation and release of environmental pollutants from different industrial sectors. Moreover, real-time monitoring can also reduce the excessive consumption of several harsh chemicals and reagents with an added advantage of on-site determination of contaminant composition prior to discharge into the environment. With key scientific advances, electrochemical biosensors have gained considerable attention to solve this problem. Electrochemical biosensors can be an excellent fit as an analytical tool for monitoring programs to implement legislation. Herein, we reviewed the current trends in the use of electrochemical biosensors as novel tools to detect various contaminant types including toxic heavy elements. A particular emphasis was given to screen-printed electrodes, nanowire sensors, and paper-based biosensors and their role in the pollution detection processes. Towards the end, the work is wrapped up with concluding remarks and future perspectives. In summary, electrochemical biosensors and related areas such as bioelectronics, and (bio)-nanotechnology seem to be growing areas that will have a marked influence on the development of new bio-sensing strategies in future studies. PMID- 29587375 TI - Coverage of Emotion Recognition for Common Wearable Biosensors. AB - The present research proposes a novel emotion recognition framework for the computer prediction of human emotions using common wearable biosensors. Emotional perception promotes specific patterns of biological responses in the human body, and this can be sensed and used to predict emotions using only biomedical measurements. Based on theoretical and empirical psychophysiological research, the foundation of autonomic specificity facilitates the establishment of a strong background for recognising human emotions using machine learning on physiological patterning. However, a systematic way of choosing the physiological data covering the elicited emotional responses for recognising the target emotions is not obvious. The current study demonstrates through experimental measurements the coverage of emotion recognition using common off-the-shelf wearable biosensors based on the synchronisation between audiovisual stimuli and the corresponding physiological responses. The work forms the basis of validating the hypothesis for emotional state recognition in the literature and presents coverage of the use of common wearable biosensors coupled with a novel preprocessing algorithm to demonstrate the practical prediction of the emotional states of wearers.

AB - Two 2-phenyl-benzofurans, moracin C {2-[3',5'-dihydroxy-4'-(3-methlbut-2 enyl)phenyl]-6-hydroxybenzofuran} and its isomer iso-moracin C{2-[3',5'-dihydroxy 4'-(3-methlbut-1-enyl)phenyl]-6-hydroxybenzofuran}, were comparatively studied using redox-related antioxidant assays and non-redox antioxidant assays. Moracin C always resulted in higher IC50 values than iso-moracin C in the redox-related antioxidant assays, including *O2--inhibition, Cu2+-reducing power, DPPH* inhibition, and ABTS+*-inhibition assays. In the non-redox antioxidant assay, moracin C and iso-moracin C underwent similar radical-adduct-formation (RAF), evidenced by the peaks at m/z 704 and m/z 618 in HPLC-MS spectra. In conclusion, both moracin C and iso-moracin C can act as 2-phenyl-benzofuran antioxidants; their antioxidant mechanisms may include redox-related ET and H+-transfer, and non-redox RAF. A double bond at the conjugation position can enhance the redox related antioxidant potential, but hardly affects the RAF potential.

AB - An ethanolic extract of Baccharis halimifolia (groundsel bush, GB), which is a native Louisiana plant with documented use in Creole folk medicine, has been shown to inhibit lipopolysaccharide (LPS)-induced inflammation in cultured macrophages. Here, we examine the effects of GB on adipocyte development and function, as these processes are attractive targets for intervention in insulin resistance. Oil Red O neutral lipid staining, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and immunoblotting were used to measure GB effects on lipid accumulation, gene expression, and protein abundance, respectively. In differentiating 3T3-L1 adipocytes, GB enhanced lipid accumulation and increased expression of several adipogenic genes (GLUT4, aP2, ADPN, CEBPalpha, FAS, and PPARgamma). Protein levels of two of these adipogenic markers (aP2 and adiponectin) were examined and found to be induced by GB treatment. In mature adipocytes, GB reduced the gene expression of resistin, a pro-inflammatory endocrine factor, increased the adiponectin protein levels in a time-dependent manner, and substantially attenuated the TNF-alpha-induced reduction in adiponectin. In macrophages, GB reduced the expression of pro inflammatory genes that were induced by LPS. GB produces metabolically favorable changes in differentiating adipocytes, mature adipocytes, and macrophages in vitro, suggesting its potential use as a dietary supplement or nutraceutical to support metabolic health and resiliency.

AB - Night-time fruit-picking technology is important to picking robots. This paper proposes a method of night-time detection and picking-point positioning for green grape-picking robots to solve the difficult problem of green grape detection and picking in night-time conditions with artificial lighting systems. Taking a representative green grape named Centennial Seedless as the research object, daytime and night-time grape images were captured by a custom-designed visual system. Detection was conducted employing the following steps: (1) The RGB (red, green and blue). Color model was determined for night-time green grape detection through analysis of color features of grape images under daytime natural light and night-time artificial lighting. The R component of the RGB color model was rotated and the image resolution was compressed; (2) The improved Chan-Vese (C-V) level set model and morphological processing method were used to remove the background of the image, leaving out the grape fruit; (3) Based on the character of grape vertical suspension, combining the principle of the minimum circumscribed rectangle of fruit and the Hough straight line detection method, straight-line fitting for the fruit stem was conducted and the picking point was calculated using the stem with an angle of fitting line and vertical line less than 15 degrees . The visual detection experiment results showed that the accuracy of grape fruit detection was 91.67% and the average running time of the proposed algorithm was 0.46 s. The picking-point calculation experiment results showed that the highest accuracy for the picking-point calculation was 92.5%, while the lowest was 80%. The results demonstrate that the proposed method of night-time green grape detection and picking-point calculation can provide technical support to the grape-picking robots. PMID- 29587380 TI - A Novel Laser and Video-Based Displacement Transducer to Monitor Bridge Deflections. AB - The measurement of static vertical deflections on bridges continues to be a first level technological challenge. These data are of great interest, especially for the case of long-term bridge monitoring; in fact, they are perhaps more valuable than any other measurable parameter. This is because material degradation processes and changes of the mechanical properties of the structure due to aging (for example creep and shrinkage in concrete bridges) have a direct impact on the exhibited static vertical deflections. This paper introduces and evaluates an approach to monitor displacements and rotations of structures using a novel laser and video-based displacement transducer (LVBDT). The proposed system combines the use of laser beams, LED lights, and a digital video camera, and was especially designed to capture static and slow-varying displacements. Contrary to other video-based approaches, the camera is located on the bridge, hence allowing to capture displacements at one location. Subsequently, the sensing approach and the procedure to estimate displacements and the rotations are described. Additionally, laboratory and in-service field testing carried out to validate the system are presented and discussed. The results demonstrate that the proposed sensing approach is robust, accurate, and reliable, and also inexpensive, which are essential for field implementation.

AB - Maintenance of atrial fibrillation is a complex mechanism, including extensive electrical and structural remodeling of the atria which involves progressive fibrogenesis. Galectin-3 is a biomarker of fibrosis, and, thus, may be involved in atrial remodeling in atrial fibrillation patients. We review the role of galectin-3 in AF mechanisms and its potential therapeutic implications. PMID- 29587381 TI - Influence of Algae Age and Population on the Response to TiO2 Nanoparticles. AB - This work shows the influence of algae age (at the time of the exposure) and the initial algae population on the response of green algae Raphidocelis subcapitata to titanium dioxide nanoparticles (TiO2 NPs). The different algae age was obtained by changes in flow rate of continually stirred tank reactors prior to NP exposure. Increased algae age led to a decreased growth, variations in chlorophyll content, and an increased lipid peroxidation. Increased initial algae population (0.3-4.2 * 106 cells/mL) at a constant NP concentration (100 mg/L) caused a decline in the growth of algae. With increased initial algae population, the lipid peroxidation and chlorophyll both initially decreased and then increased. Lipid peroxidation had 4* the amount of the control at high and low initial population but, at mid-ranged initial population, had approximately half the control value. Chlorophyll a results also showed a similar trend. These results indicate that the physiological state of the algae is important for the toxicological effect of TiO2 NPs. The condition of algae and exposure regime must be considered in detail when assessing the toxicological response of NPs to algae. PMID- 29587382 TI - Functional Characterization of Novel Atrial Fibrillation-Linked GJA5 (Cx40) Mutants. AB - Atrial fibrillation (AF) is the most common form of cardiac arrhythmia. Recently, four novel heterozygous Cx40 mutations-K107R, L223M, Q236H, and I257L-were identified in 4 of 310 unrelated AF patients and a followup genetic analysis of the mutant carriers' families showed that the mutants were present in all the affected members. To study possible alterations associated with these Cx40 mutants, including their cellular localization and gap junction (GJ) function, we expressed GFP-tagged and untagged mutants in connexin-deficient model cells. All four Cx40 mutants showed clustered localization at cell-cell junctions similar to that observed of wildtype Cx40. However, cell pairs expressing Cx40 Q236H, but not the other individual mutants, displayed a significantly lower GJ coupling conductance (Gj) than wildtype Cx40. Similarly, co-expression of Cx40 Q236H with Cx43 resulted in a significantly lower Gj. Transjunctional voltage-dependent gating (Vj gating) properties were also altered in the GJs formed by Q236H. Reduced GJ function and altered Vj gating may play a role in promoting the Q236H carriers to AF. PMID- 29587383 TI - Protein Expression in Tonsillar and Base of Tongue Cancer and in Relation to Human Papillomavirus (HPV) and Clinical Outcome. AB - Human papillomavirus (HPV) is a major etiological factor for tonsillar and the base of tongue cancer (TSCC/BOTSCC). HPV-positive and HPV-negative TSCC/BOTSCC present major differences in mutations, mRNA expression and clinical outcome. Earlier protein studies on TSCC/BOTSCC have mainly analyzed individual proteins. Here, the aim was to compare a larger set of cancer and immune related proteins in HPV-positive and HPV-negative TSCC/BOTSCC in relation to normal tissue, presence of HPV, and clinical outcome. Fresh frozen tissue from 42 HPV-positive and 17 HPV-negative TSCC/BOTSCC, and corresponding normal samples, were analyzed for expression of 167 proteins using two Olink multiplex immunoassays. Major differences in protein expression between TSCC/BOTSCC and normal tissue were identified, especially in chemo- and cytokines. Moreover, 34 proteins, mainly immunoregulatory proteins and chemokines, were differently expressed in HPV positive vs HPV-negative TSCC/BOTSCC. Several proteins were potentially related to clinical outcome for HPV-positive or HPV-negative tumors. For HPV-positive tumors, these were mostly related to angiogenesis and hypoxia. Correlation with clinical outcome of one of these, VEGFA, was validated by immunohistochemistry. Differences in immune related proteins between HPV-positive and HPV-negative TSCC/BOTSCC reflect the stronger activity of the immune defense in the former. Angiogenesis related proteins might serve as potential targets for therapy in HPV positive TSCC/BOTSCC. PMID- 29587384 TI - High Glucose-Mediated Tyrosine Nitration of PI3-Kinase: A Molecular Switch of Survival and Apoptosis in Endothelial Cells. AB - Diabetes and hyperglycemia are associated with increased retinal oxidative and nitrative stress and vascular cell death. Paradoxically, high glucose stimulates expression of survival and angiogenic growth factors. Therefore, we examined the hypothesis that high glucose-mediated tyrosine nitration causes inhibition of the survival protein PI3-kinase, and in particular, its regulatory p85 subunit in retinal endothelial cell (EC) cultures. Retinal EC were cultured in high glucose (HG, 25 mM) for 3 days or peroxynitrite (PN, 100 uM) overnight in the presence or absence of a peroxynitrite decomposition catalyst (FeTPPs, 2.5 uM), or the selective nitration inhibitor epicatechin (100 uM). Apoptosis of ECs was assessed using TUNEL assay and caspase-3 activity. Immunoprecipitation and Western blot were used to assess protein expression and tyrosine nitration of p85 subunit and its interaction with the p110 subunit. HG or PN accelerated apoptosis of retinal ECs compared to normal glucose (NG, 5 mM) controls. HG- or PN-treated cells also showed significant increases in tyrosine nitration on the p85 subunit of PI3 kinase that inhibited its association with the catalytic p110 subunit and impaired PI3-kinase/Akt kinase activity. Decomposing peroxynitrite or blocking tyrosine nitration of p85 restored the activity of PI3-kinase, and prevented apoptosis and activation of p38 MAPK. Inhibiting p38 MAPK or overexpression of the constitutively activated Myr-Akt construct prevented HG- or peroxynitrite mediated apoptosis. In conclusion, HG impairs pro-survival signals and causes accelerated EC apoptosis, at least in part via tyrosine nitration and inhibition of PI3-kinase. Inhibitors of nitration can be used in adjuvant therapy to delay diabetic retinopathy and microvascular complication. PMID- 29587385 TI - Label-Free Electrochemical Detection of Vanillin through Low-Defect Graphene Electrodes Modified with Au Nanoparticles. AB - Graphene is an excellent modifier for the surface modification of electrochemical electrodes due to its exceptional physical properties and, for the development of graphene-based chemical and biosensors, is usually coated on glassy carbon electrodes (GCEs) via drop casting. However, the ease of aggregation and high defect content of reduced graphene oxides degrade the electrical properties. Here, we fabricated low-defect graphene electrodes by catalytically thermal treatment of HPHT diamond substrate, followed by the electrodeposition of Au nanoparticles (AuNPs) with an average size of ~60 nm on the electrode surface using cyclic voltammetry. The Au nanoparticle-decorated graphene electrodes show a wide linear response range to vanillin from 0.2 to 40 uM with a low limit of detection of 10 nM. This work demonstrates the potential applications of graphene based hybrid electrodes for highly sensitive chemical detection. PMID- 29587387 TI - Thylakoid-Deposited Micro-Pillar Electrodes for Enhanced Direct Extraction of Photosynthetic Electrons. AB - Photosynthesis converts solar energy to electricity in a highly efficient manner. Since only water is needed as fuel for energy conversion, this highly efficient energy conversion process has been rigorously investigated. In particular, photosynthetic apparatus, such as photosystem II (PSII), photosystem I (PSI), or thylakoids, have been isolated from various plants to construct bio-hybrid anodes. Although PSII or PSI decorated anodes have shown potentials, there still remain challenges, such as poor stability of PSII-based systems or need for electron donors other than water molecules of PSI-based systems. Thylakoid membranes are relatively stable after isolation and they contain all the necessary photosynthetic apparatus including the PSII and PSI. To increase electrical connections between thylakoids and anodes, nanomaterials such as carbon nanotubes, nanowires, nanoparticles, or graphene have been employed. However, since they rely on the secondary electrical connections between thylakoids and anodes; it is desired to achieve larger direct contacts between them. Here, we aimed to develop micro-pillar (MP) array anodes to maximize direct contact with thylakoids. The thylakoid morphology was analyzed and the MP array was designed to maximize direct contact with thylakoids. The performance of MP anodes and a photosynthetic fuel cell based on MP electrodes was demonstrated and analyzed. PMID- 29587386 TI - Co2 and Co3 Mixed Cluster Secondary Building Unit Approach toward a Three Dimensional Metal-Organic Framework with Permanent Porosity. AB - Large and permanent porosity is the primary concern when designing metal-organic frameworks (MOFs) for specific applications, such as catalysis and drug delivery. In this article, we report a MOF Co11(BTB)6(NO3)4(DEF)2(H2O)14 (1, H3BTB = 1,3,5 tris(4-carboxyphenyl)benzene; DEF = N,N-diethylformamide) via a mixed cluster secondary building unit (SBU) approach. MOF 1 is sustained by a rare combination of a linear trinuclear Co3 and two types of dinuclear Co2 SBUs in a 1:2:2 ratio. These SBUs are bridged by BTB ligands to yield a three-dimensional (3D) non interpenetrated MOF as a result of the less effective packing due to the geometrically contrasting SBUs. The guest-free framework of 1 has an estimated density of 0.469 g cm-3 and exhibits a potential solvent accessible void of 69.6% of the total cell volume. The activated sample of 1 exhibits an estimated Brunauer-Emmett-Teller (BET) surface area of 155 m2 g-1 and is capable of CO2 uptake of 58.61 cm3 g-1 (2.63 mmol g-1, 11.6 wt % at standard temperature and pressure) in a reversible manner at 195 K, showcasing its permanent porosity. PMID- 29587388 TI - Liquid Phase Plasma Synthesis of Iron Oxide Nanoparticles on Nitrogen-Doped Activated Carbon Resulting in Nanocomposite for Supercapacitor Applications. AB - Iron oxide nanoparticles supported on nitrogen-doped activated carbon powder were synthesized using an innovative plasma-in-liquid method, called the liquid phase plasma (LPP) method. Nitrogen-doped carbon (NC) was prepared by a primary LPP reaction using an ammonium chloride reactant solution, and an iron oxide/NC composite (IONCC) was prepared by a secondary LPP reaction using an iron chloride reactant solution. The nitrogen component at 3.77 at. % formed uniformly over the activated carbon (AC) surface after a 1 h LPP reaction. Iron oxide nanoparticles, 40~100 nm in size, were impregnated homogeneously over the NC surface after the LPP reaction, and were identified as Fe3O4 by X-ray photoelectron spectroscopy and X-ray diffraction. NC and IONCCs exhibited pseudo-capacitive characteristics, and their specific capacitance and cycling stability were superior to those of bare AC. The nitrogen content on the NC surface increased the compatibility and charge transfer rate, and the composites containing iron oxide exhibited a lower equivalent series resistance. PMID- 29587389 TI - Lynch Syndrome-Related Clear Cell Carcinoma of the Cervix: A Case Report. AB - Lynch syndrome, a hereditary cancer syndrome, occurs because of germline mutations in at least one of four DNA mismatch repair genes (MutL Homolog 1 (MLH1), MutS Homolog 2 (MSH2), MutS Homolog 6 (MSH6), and PMS1 Homolog 2 (PMS2)). The disorder is associated with colorectal, endometrial, and other epithelial malignancies, but not cervical cancer. We report a woman with Lynch syndrome with synchronous cervical cancer. This is the first report of Lynch syndrome-related clear cell carcinoma of the cervix, which indicates the possibility of an association between cervical cancer and Lynch syndrome. Suitable genetic tests are required to determine whether common genetics can account for synchronous or subsequent malignancies in Lynch syndrome patients and their families. Such knowledge will also enhance our understanding of the genetic mechanisms governing the development of apparently unrelated cancers. PMID- 29587390 TI - Sedentary Behaviour and Hair Cortisol Amongst Women Living in Socioeconomically Disadvantaged Neighbourhoods: A Cross-Sectional Study. AB - Women living in socioeconomically disadvantaged neighbourhoods are at heightened risk of experiencing psychological stress. Therefore, identifying potential risk factors for stress is important to support positive mental health. A growing body of research has linked sedentary behaviour with mental ill-health (e.g., depression and anxiety); however, little research has specifically investigated potential linkages between sedentary behaviour and stress. Therefore, the aim of this study was to investigate the association between common types of sedentary behaviour and objectively-measured stress (as measured by hair cortisol levels) amongst women living in socioeconomically disadvantaged neighbourhoods. During 2012-2013, 72 women (aged 18-46 years) living in socioeconomically disadvantaged neighbourhoods self-reported sedentary behaviour (TV viewing, computer use, overall sitting time) and provided hair samples. Hair cortisol levels were measured using enzyme-linked immunosorbent assay. Linear regression models examined cross-sectional associations between sedentary behaviour and hair cortisol levels. There was no association between any type of sedentary behaviour (TV viewing, computer use, or overall sitting time) and hair cortisol levels in either crude or adjusted models. Sedentary behaviour may not be linked to hair cortisol level (stress) in women living in socioeconomically disadvantaged neighbourhoods. Further studies utilising objective measures of both sedentary behaviour and stress are required to confirm these findings. PMID- 29587391 TI - Nondestructive Estimation of Muscle Contributions to STS Training with Different Loadings Based on Wearable Sensor System. AB - Partial body weight support or loading sit-to-stand (STS) rehabilitation can be useful for persons with lower limb dysfunction to achieve movement again based on the internal residual muscle force and external assistance. To explicate how the muscles contribute to the kinetics and kinematics of STS performance by non invasive in vitro detection and to nondestructively estimate the muscle contributions to STS training with different loadings, a wearable sensor system was developed with ground reaction force (GRF) platforms, motion capture inertial sensors and electromyography (EMG) sensors. To estimate the internal moments of hip, knee and ankle joints and quantify the contributions of individual muscle and gravity to STS movement, the inverse dynamics analysis on a simplified STS biomechanical model with external loading is proposed. The functional roles of the lower limb individual muscles (rectus femoris (RF), gluteus maximus (GM), vastus lateralis (VL), tibialis anterior (TA) and gastrocnemius (GAST)) during STS motion and the mechanism of the muscles' synergies to perform STS-specific subtasks were analyzed. The muscle contributions to the biomechanical STS subtasks of vertical propulsion, anteroposterior (AP) braking and propulsion for body balance in the sagittal plane were quantified by experimental studies with EMG, kinematic and kinetic data. PMID- 29587392 TI - Correction of Visual Perception Based on Neuro-Fuzzy Learning for the Humanoid Robot TEO. AB - New applications related to robotic manipulation or transportation tasks, with or without physical grasping, are continuously being developed. To perform these activities, the robot takes advantage of different kinds of perceptions. One of the key perceptions in robotics is vision. However, some problems related to image processing makes the application of visual information within robot control algorithms difficult. Camera-based systems have inherent errors that affect the quality and reliability of the information obtained. The need of correcting image distortion slows down image parameter computing, which decreases performance of control algorithms. In this paper, a new approach to correcting several sources of visual distortions on images in only one computing step is proposed. The goal of this system/algorithm is the computation of the tilt angle of an object transported by a robot, minimizing image inherent errors and increasing computing speed. After capturing the image, the computer system extracts the angle using a Fuzzy filter that corrects at the same time all possible distortions, obtaining the real angle in only one processing step. This filter has been developed by the means of Neuro-Fuzzy learning techniques, using datasets with information obtained from real experiments. In this way, the computing time has been decreased and the performance of the application has been improved. The resulting algorithm has been tried out experimentally in robot transportation tasks in the humanoid robot TEO (Task Environment Operator) from the University Carlos III of Madrid. PMID- 29587393 TI - Roma Housing and Eating in 1775 and 2013: A Comparison. AB - We compared housing and the eating habits of Roma. Contemporary findings (2013) were compared with those from the first monothematic work on Roma (1775), which depicts their housing and eating habits, especially regarding the differences between social classes. Data were obtained from a journal (1775) and from semi structured interviews (2013) with more than 70 Roma women and men who live in segregated and excluded settlements at the edges of villages or scattered among the majority. Data were collected in two villages and one district town in the Tatra region, where the data from the 1775 measurements originated. We used classical sociological theory to interpret the obtained data. The main findings showed differences between specific social classes then and now regarding housing, as well as the eating habits related to both conditions among the Roma in the Tatra region. The houses of rich Roma families did not differ from the houses of the majority population. The huts of the poorest inhabitants of settlements did not meet any hygiene standards. Typical Roma foods such as goja or marikla were the traditional foods of Slovak peasants living in poverty in the country. We concluded that the housing and eating habits of the citizens of poor settlements located in the eastern parts of Slovakia are still similar to those of two centuries ago. The existing social exclusion may be explained partly from this finding. PMID- 29587394 TI - Synthesis and Evaluation of the Anticonvulsant Activities of 4-(2 (Alkylthio)benzo[d]oxazol-5-yl)-2,4-dihydro-3H-1,2,4-triazol-3-ones. AB - In this study, a novel series of 4-(2-(alkylthio)benzo[d]oxazol-5-yl)-2,4-dihydro 3H-1,2,4-triazol-3-ones (4a-m) was designed and synthesized. The anticonvulsant activities of these compounds were evaluated by using the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure models in mice. The neurotoxicity of these compounds was evaluated using the rotarod neurotoxicity test. The majority of compounds showed anti-MES activities at 100 or 300 mg/kg. Compound 4g was considered to be the most promising, based on its potency against MES- and PTZ-induced seizures with ED50 values of 23.7 and 18.9 mg/kg, respectively. The TD50 value of 4g was 284.0 mg/kg, which resulted in a higher protective index (PI = TD50/ED50) value than that of carbamazepine and valproate. In an ELISA test, compound 4g significantly increased the gamma aminobutyric acid (GABA) content in mouse brain. In addition, pretreatment with thiosemicarbazide (an inhibitor of the GABA synthesizing enzyme) significantly decreased the activity of 4g in the MES model, which suggests that the mechanism through which compound 4g elicits its anticonvulsive action is at least in part through increasing the GABA level in the brain. PMID- 29587395 TI - Long-Time Relaxation of Stress-Induced Birefringence of Microcrystalline Alkali Halide Crystals. AB - Alkali halide single crystals are most commonly used as the diluent matrix in the tablet method or disk technique for spectroscopic measurements. However, stress induced birefringence (SIB) of alkali halides as well as intrinsic birefringence manifest during the disk formation process. Thus, the true chiroptical measurement is disturbed by optical anisotropies (OA) containing SIB and intrinsic birefringence, except in the case of optical homogeneity. SIB is generally larger than intrinsic birefringence and has a value of several thousand millidegrees in the ultraviolet-visible wavelength range, although this varies with disk type. Here, to investigate the SIB origin, alkali halide crystals were examined using polarized light, X-ray diffraction, Fourier-transform infrared, and electron backscattering diffraction spectroscopic measurements. It was found that, after stress release, the SIB exhibited nonlinear long-time relaxation, which roughly converged within several hours, with the only time-invariant intrinsic birefringence remaining being due to OA. This behavior was strongly related to an increase in the quasi-amorphous domain and the generation of an air gap between the crystallite boundaries and their pellets. Further, a straightforward correlation was found between amorphization and an increase in the disk water content caused by deliquescence. Thus, the OA of alkali halide single crystals was found to have two different origins yielding intrinsic birefringence and SIB. PMID- 29587396 TI - A Portable Wireless Communication Platform Based on a Multi-Material Fiber Sensor for Real-Time Breath Detection. AB - In this paper, we present a new mobile wireless communication platform for real time monitoring of an individual's breathing rate. The platform takes the form of a wearable stretching T-shirt featuring a sensor and a detection base station. The sensor is formed by a spiral-shaped antenna made from a multi-material fiber connected to a compact transmitter. Based on the resonance frequency of the antenna at approximately 2.4 GHz, the breathing sensor relies on its Bluetooth transmitter. The contactless and non-invasive sensor is designed without compromising the user's comfort. The sensing mechanism of the system is based on the detection of the signal amplitude transmitted wirelessly by the sensor, which is found to be sensitive to strain. We demonstrate the capability of the platform to detect the breathing rates of four male volunteers who are not in movement. The breathing pattern is obtained through the received signal strength indicator (RSSI) which is filtered and analyzed with home-made algorithms in the portable system. Numerical simulations of human breath are performed to support the experimental detection, and both results are in a good agreement. Slow, fast, regular, irregular, and shallow breathing types are successfully recorded within a frequency interval of 0.16-1.2 Hz, leading to a breathing rate varying from 10 to 72 breaths per minute.

AB - Humans are exposed to the environmental pollutants 2,4-dichlorophenol (2,4-DCP) and 2,5-dichlorophenol (2,5-DCP) through air, the use of water and the consumption of products. In this study, we evaluated the urinary concentrations of these compounds in Korean people between the ages of 18 to 69 years, by making use of data from the Korean National Human Biomonitoring Survey that was completed in 2009. Of 1865 representative Koreans, 63.4% and 97.9% were found to have concentrations of 2,4-DCP and 2,5-DCP > 0.05 MUg/L (limit of detection) in their urine, respectively. The geometric mean of urinary concentrations was 0.14 MUg/L (confidence interval of 95% = 0.13-0.16) and 0.44 MUg/L (confidence interval = 0.41-0.48), respectively. It was found that the adjusted proportional changes in 2,4-DCP concentrations were significantly associated with body mass index, whereas those of 2,5-DCP concentrations were influenced by place of residence. From these findings, it is evident that most adults in Korea have levels of 2,4-DCP and 2,5-DCP that are detectable in their urine and the burden of these compounds on their bodies varies depending on numerous demographic factors.

AB - To overcome yearly efforts and costs for the production of seasonal influenza vaccines, new approaches for the induction of broadly protective and long-lasting immune responses have been developed in the past decade. To warrant safety and efficacy of the emerging crossreactive vaccine candidates, it is critical to understand the evolution of influenza viruses in response to these new immune pressures. Here we applied unique molecular identifiers in next generation sequencing to analyze the evolution of influenza quasispecies under in vivo antibody pressure targeting the hemagglutinin (HA) long alpha helix (LAH). Our vaccine targeting LAH of hemagglutinin elicited significant seroconversion and protection against homologous and heterologous influenza virus strains in mice. The vaccine not only significantly reduced lung viral titers, but also induced a well-known bottleneck effect by decreasing virus diversity. In contrast to the classical bottleneck effect, here we showed a significant increase in the frequency of viruses with amino acid sequences identical to that of vaccine targeting LAH domain. No escape mutant emerged after vaccination. These results not only support the potential of a universal influenza vaccine targeting the conserved LAH domains, but also clearly demonstrate that the well-established bottleneck effect on viral quasispecies evolution does not necessarily generate escape mutants.

AB - The development of information technology has paved the way for faster and more convenient payment process flows and new methodology for the design and implementation of next generation payment systems. The growth of smartphone usage nowadays has fostered a new and popular mobile payment environment. Most of the current generation smartphones support Bluetooth Low Energy (BLE) technology to communicate with nearby BLE-enabled devices. It is plausible to construct an Over the-Air BLE-based mobile payment system as one of the payment methods for people living in modern societies. In this paper, a secure indoor positioning-based mobile payment authentication protocol with BLE technology and the corresponding mobile payment system design are proposed. The proposed protocol consists of three phases: initialization phase, session key construction phase, and authentication phase. When a customer moves toward the POS counter area, the proposed mobile payment system will automatically detect the position of the customer to confirm whether the customer is ready for the checkout process. Once the system has identified the customer is standing within the payment-enabled area, the payment system will invoke authentication process between POS and the customer's smartphone through BLE communication channel to generate a secure session key and establish an authenticated communication session to perform the payment transaction accordingly. A prototype is implemented to assess the performance of the proposed design for mobile payment system. In addition, security analysis is conducted to evaluate the security strength of the proposed protocol.

AB - Background: Few studies have investigated the longitudinal association between cervical spondylosis (CS) and migraine by using a nationwide population-based database. Methods: We conducted a retrospective cohort study from 2000 to 2011 identifying 27,930 cases of cervical spondylosis and 111,720 control subjects (those without cervical spondylosis) from a single database. The subjects were frequency-matched on the basis of sex, age, and diagnosis date. The non- cervical spondylosis cohort was four times the size of the cervical spondylosis cohort. To quantify the effects of cervical spondylosis on the risk of migraine, univariate and multivariate Cox proportional hazard regression analyses were used to calculate the hazard ratio (HR), and 95% confidence interval (CI). Results: After a 10-year follow-up controlling for potential confounding factors, overall migraine incidence was higher in the cervical spondylosis cohort than in the non cervical spondylosis cohort (5.16 and 2.09 per 1000 people per year, respectively; crude hazard ratio = 2.48, 95% confidence interval = 2.28-2.69), with an adjusted hazard ratio of 2.03 (95% confidence interval = 1.86-2.22) after accounting for sex, age, comorbidities, and medication. Individuals with myelopathy in the cervical spondylosis cohort had a 2.19 times (95% confidence interval = 1.80-2.66) higher incidence of migraine when compared than did those in the non- cervical spondylosis cohort. Conclusions: Individuals with cervical spondylosis exhibited a higher risk of migraine than those without cervical spondylosis. The migraine incidence rate was even higher among individuals with cervical spondylotic myelopathy.

AB - (1) Background: An outdoor gym (OG) is environmental infrastructure built in a public open space to promote structured physical activity. The provision of OGs is increasingly seen as an important strategy to realize public health agendas promoting habitual physical activity. A systematic review was conducted to synthesize characteristics of OG and OG users' experiences and perceptions in different cultural contexts; (2) Methods: Online searches of multidisciplinary databases were conducted in health, sport and recreation, and urban planning disciplines. Characteristics of OGs were synthesized by integrating evidence from quantitative, qualitative, and mix-methods studies. The experiences and perceptions of OG users from both qualitative data and survey responses were synthesized through framework analysis; (3) Results: Nine studies met the inclusion criteria (three quantitative studies, four mixed-methods studies, and two pure qualitative studies). None were excluded on the basis of quality. OGs mainly serve adult and older adult population groups. Their size, design, and instructional support vary across studies. The inclusion of functional types of equipment did not have a unified standard. Regarding experiences and perceptions of OGs, five major themes emerged: "health", "social connectedness", "affordable", "support", and "design and promotion"; (4) Conclusions: The OG characteristics synthesis guides the direction in further studies regarding exploration of design parameters. The qualitative and quantitative synthesis revealed that health was a central theme of users' experiences. OGs are also spaces where community-dwellers can find social connectedness while participating in structured physical activity at no cost. Findings from this review create knowledge support for OG as environmental infrastructure for further research and facilitate the understanding of users' experiences and perceptions of OGs in different cultural contexts. PMID- 29587401 TI - Inactivation of SREBP-1a Phosphorylation Prevents Fatty Liver Disease in Mice: Identification of Related Signaling Pathways by Gene Expression Profiles in Liver and Proteomes of Peroxisomes. AB - The key lipid metabolism transcription factor sterol regulatory element-binding protein (SREBP)-1a integrates gene regulatory effects of hormones, cytokines, nutrition and metabolites as lipids, glucose, or cholesterol via phosphorylation by different mitogen activated protein kinase (MAPK) cascades. We have previously reported the impact of SREBP-1a phosphorylation on the phenotype in transgenic mouse models with liver-specific overexpression of the N-terminal transcriptional active domain of SREBP-1a (alb-SREBP-1a) or a MAPK phosphorylation site-deficient variant (alb-SREBP-1a?P; (S63A, S117A, T426V)), respectively. In this report, we investigated the molecular basis of the systemic observations by holistic analyses of gene expression in liver and of proteome patterns in lipid-degrading organelles involved in the pathogenesis of metabolic syndrome, i.e., peroxisomes, using 2D-DIGE and mass spectrometry. The differences in hepatic gene expression and peroxisomal protein patterns were surprisingly small between the control and alb-SREBP-1a mice, although the latter develop a severe phenotype with visceral obesity and fatty liver. In contrast, phosphorylation site-deficient alb-SREBP 1a?P mice, which are protected from fatty liver disease, showed marked differences in hepatic gene expression and peroxisomal proteome patterns. Further knowledge-based analyses revealed that disruption of SREBP-1a phosphorylation resulted in massive alteration of cellular processes, including signs for loss of targeting lipid pathways. PMID- 29587403 TI - Non-Invasive Methodology to Estimate Polyphenol Content in Extra Virgin Olive Oil Based on Stepwise Multilinear Regression. AB - Normally the olive oil quality is assessed by chemical analysis according to international standards. These norms define chemical and organoleptic markers, and depending on the markers, the olive oil can be labelled as lampante, virgin, or extra virgin olive oil (EVOO), the last being an indicator of top quality. The polyphenol content is related to EVOO organoleptic features, and different scientific works have studied the positive influence that these compounds have on human health. The works carried out in this paper are focused on studying relations between the polyphenol content in olive oil samples and its spectral response in the near infrared spectra. In this context, several acquisition parameters have been assessed to optimize the measurement process within the virgin olive oil production process. The best regression model reached a mean error value of 156.14 mg/kg in leave one out cross validation, and the higher regression coefficient was 0.81 through holdout validation. PMID- 29587404 TI - Identification of Dysregulated microRNA Networks in Schwann Cell-Like Cultures Exposed to Immune Challenge: Potential Crosstalk with the Protective VIP/PACAP Neuropeptide System. AB - Following peripheral nerve injury, dysregulations of certain non-coding microRNAs (miRNAs) occur in Schwann cells. Whether these alterations are the result of local inflammation and/or correlate with perturbations in the expression profile of the protective vasoactive intestinal peptide (VIP)/pituitary adenylate cyclase activating polypeptide (PACAP) system is currently unknown. To address these issues, we aimed at profiling the expression of selected miRNAs in the rat RT4 Schwann cell line. Cells exposed to lipopolysaccharide (LPS), to mimic the local inflammatory milieu, were appraised by real-time qPCR, Western blot and ELISAs. We found that upon LPS treatment, levels of pro-inflammatory cytokines (IL-1beta, -6, -18, -17A, MCP-1 and TNFalpha) increased in a time-dependent manner. Unexpectedly, the expression levels of VIP and PACAP were also increased. Conversely, levels of VPAC1 and VPAC2 receptors were reduced. Downregulated miRNAs included miR-181b, -145, -27a, -340 and -132 whereas upregulated ones were miR-21, -206, -146a, -34a, -155, -204 and -29a, respectively. Regression analyses revealed that a subset of the identified miRNAs inversely correlated with the expression of VPAC1 and VPAC2 receptors. In conclusion, these findings identified a novel subset of miRNAs that are dysregulated by immune challenge whose activities might elicit a regulatory function on the VIP/PACAP system. PMID- 29587405 TI - Further New Diterpenoids as PTP1B Inhibitors from the Xisha Soft Coral Sinularia polydactyla. AB - A new prenyleudesmane type diterpene, sinupol (8), and a new capnosane type diterpenoid, sinulacetate (9), were isolated from the Xisha soft coral Sinularia polydactyla along with five known related diterpenes (4-7 and 10). Their structures, including absolute configurations, were determined by extensive spectroscopic analysis, the comparison of their NMR data with those of related compounds, and time-dependent density functional theory electronic circular dichroism (TDDFT ECD) calculations. Both new compounds (8 and 9) exhibited promising inhibitory activity against protein tyrosine phosphatase 1B (PTP1B), a potential drug target for the treatment of type II diabetes and obesity. PMID- 29587406 TI - Characterization of Phenolic Compounds in Wine Lees. AB - The effect of vinification techniques on phenolic compounds and antioxidant activity of wine lees are poorly understood. The present study investigated the antioxidant activity of white and red wine lees generated at early fermentation and during aging. In this study, the total phenol content (TPC), total tannin content (TTC), mean degree of polymerization (mDP), and antioxidant activities of five white and eight red wine lees samples from different vinification backgrounds were determined. The results showed that vinification techniques had a significant (p < 0.05) impact on total phenol and tannin content of the samples. White wine lees had high mDP content compared with red ones. Catechin (50-62%) and epicatechin contents were the predominant terminal units of polymeric proanthocyanidin extracted from examined samples. Epigallocatechin was the predominant extension unit of white wine lees, whereas epicatechin was the predominant compound in red wine marc. The ORAC (oxygen radical absorbance capacity) assay was strongly correlated with the DPPH (alpha, alpha-diphenyl-beta picrylhydrazyl) assay, and the results showed the strong antioxidant activities associated with red wine lees (PN > 35 mg Trolox/g FDM) (PN: Pinot noir lees; FDM: Freeze-dried Material). This study indicates that tannin is one of the major phenolic compounds available in wine lees that can be useful in human and animal health applications. PMID- 29587407 TI - Ultra-Long-Distance Hybrid BOTDA/F-OTDR. AB - In the distributed optical fiber sensing (DOFS) domain, simultaneous measurement of vibration and temperature/strain based on Rayleigh scattering and Brillouin scattering in fiber could have wide applications. However, there are certain challenges for the case of ultra-long sensing range, including the interplay of different scattering mechanisms, the interaction of two types of sensing signals, and the competition of pump power. In this paper, a hybrid DOFS system, which can simultaneously measure temperature/strain and vibration over 150 km, is elaborately designed via integrating the Brillouin optical time-domain analyzer (BOTDA) and phase-sensitive optical time-domain reflectometry (F-OTDR). Distributed Raman and Brillouin amplifications, frequency division multiplexing (FDM), wavelength division multiplexing (WDM), and time division multiplexing (TDM) are delicately fused to accommodate ultra-long-distance BOTDA and F-OTDR. Consequently, the sensing range of the hybrid system is 150.62 km, and the spatial resolution of BOTDA and F-OTDR are 9 m and 30 m, respectively. The measurement uncertainty of the BOTDA is +/- 0.82 MHz. To the best of our knowledge, this is the first time that such hybrid DOFS is realized with a hundred-kilometer length scale. PMID- 29587408 TI - Trauma and Depression among North Korean Refugees: The Mediating Effect of Negative Cognition. AB - North Korean refugees experience adaptation difficulties, along with a wide range of psychological problems. Accordingly, this study examined the associations between early traumatic experiences, negative automatic thoughts, and depression among young North Korean refugees living in South Korea. Specifically, we examined how different factors of negative automatic thoughts would mediate the relationship between early trauma and depressive symptoms. A total of 109 North Korean refugees aged 13-29 years were recruited from two alternative schools. Our path analysis indicated that early trauma was positively linked with thoughts of personal failure, physical threat, and hostility, but not with thoughts of social threat. The link with depressive symptoms was only significant for thoughts of personal failure. After removing all non-significant pathways, the model revealed that early traumatic experiences were positively associated with depressive symptoms (beta = 0.61, 95% CI = 0.48-0.73) via thoughts of personal failure (beta = 0.17, 95% CI = 0.08-0.28), as well as directly (beta = 0.44, 95% CI = 0.27 0.59). Interventions that target negative cognitions of personal failure may be helpful for North Korean refugees at risk of depression. PMID- 29587410 TI - Osteogenic Potential of Pre-Osteoblastic Cells on a Chitosan-graft Polycaprolactone Copolymer. AB - A chitosan-graft-polycaprolactone (CS-g-PCL) copolymer synthesized via a multi step process was evaluated as a potential biomaterial for the adhesion and growth of MC3T3-E1 pre-osteoblastic cells. A strong adhesion of the MC3T3-E1 cells with a characteristic spindle-shaped morphology was observed from the first days of cell culture onto the copolymer surfaces. The viability and proliferation of the cells on the CS-g-PCL surfaces, after 3 and 7 days in culture, were significantly higher compared to the cells cultured on the tissue culture treated polystyrene (TCPS) control. The osteogenic potential of the pre-osteoblastic cells cultured on CS-g-PCL surfaces was evaluated by determining various osteogenic differentiation markers and was compared to the TCPS control surface. Specifically, alkaline phosphatase activity levels show significantly higher values at both time points compared to TCPS, while secreted collagen into the extracellular matrix was found to be higher on day 7. Calcium biomineralization deposited into the matrix is significantly higher for the CS-g-PCL copolymer after 14 days in culture, while the levels of intracellular osteopontin were significantly higher on the CS-g-PCL surfaces compared to TCPS. The enhanced osteogenic response of the MC3T3-E1 pre-osteoblasts cultured on CS-g-PCL reveals that the copolymer underpins the cell functions towards bone tissue formation and is thus an attractive candidate for use in bone tissue engineering. PMID- 29587409 TI - Nose-to-Brain Delivery of Antiviral Drugs: A Way to Overcome Their Active Efflux? AB - Although several viruses can easily infect the central nervous system (CNS), antiviral drugs often show dramatic difficulties in penetrating the brain from the bloodstream since they are substrates of active efflux transporters (AETs). These transporters, located in the physiological barriers between blood and the CNS and in macrophage membranes, are able to recognize their substrates and actively efflux them into the bloodstream. The active transporters currently known to efflux antiviral drugs are P-glycoprotein (ABCB1 or P-gp or MDR1), multidrug resistance-associated proteins (ABCC1 or MRP1, ABCC4 or MRP4, ABCC5 or MRP5), and breast cancer resistance protein (ABCG2 or BCRP). Inhibitors of AETs may be considered, but their co-administration causes serious unwanted effects. Nasal administration of antiviral drugs is therefore proposed in order to overcome the aforementioned problems, but innovative devices, formulations (thermoreversible gels, polymeric micro- and nano-particles, solid lipid microparticles, nanoemulsions), absorption enhancers (chitosan, papaverine), and mucoadhesive agents (chitosan, polyvinilpyrrolidone) are required in order to selectively target the antiviral drugs and, possibly, the AET inhibitors in the CNS. Moreover, several prodrugs of antiretroviral agents can inhibit or elude the AET systems, appearing as interesting substrates for innovative nasal formulations able to target anti-Human Immunodeficiency Virus (HIV) agents into macrophages of the CNS, which are one of the most important HIV Sanctuaries of the body. PMID- 29587411 TI - Relationship between Response to PDE5 Inhibitors and Penile Duplex Doppler Ultrasound in Erectile Dysfunction. AB - The relationship between the results of penile duplex Doppler ultrasound (PDDU) and response to vardenafil was investigated in patients diagnosed with erectile dysfunction (ED). Data from 148 patients with ED were analyzed retrospectively. Patients who did not respond to therapy were classified in to Group I (n = 32), those who responded partially were classified into Group II (n = 40), and complete responders were classified into Group III (n = 76). Age, comorbidities, and vascular and penile pathologies were compared among the three groups. While diabetes mellitus (DM) and dyslipidemia positivity adversely affected the response to treatment, the presence of hypertension (HT), Peyronie's disease and priapism increased the therapeutic response to the treatment (p < 0.05). Arterial insufficiency was present in 20 (30.3%), 25 (37.9%) and 21 (31.8%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). Venous insufficiency was observed in three (14.3%) patients in Group I and in eight (85.7%) patients in Group III (p = 0.001). Arterial/venous insufficiency was seen in 9 (30%), 14 (46.7%) and 7 (23.3%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). The response rate to treatment was highest in normal patients according to PDDU, followed by patients with venous insufficiency. In addition, it was found that DM decreased the response to treatment, whereas the response increased in cases with HT, priapism and Peyronie's disease. PMID- 29587412 TI - Epidemiological Studies to Support the Development of Next Generation Influenza Vaccines. AB - The National Institute of Allergy and Infectious Diseases recently published a strategic plan for the development of a universal influenza vaccine. This plan focuses on improving understanding of influenza infection, the development of influenza immunity, and rational design of new vaccines. Epidemiological studies such as prospective, longitudinal cohort studies are essential to the completion of these objectives. In this review, we discuss the contributions of epidemiological studies to our current knowledge of vaccines and correlates of immunity, and how they can contribute to the development and evaluation of the next generation of influenza vaccines. These studies have been critical in monitoring the effectiveness of current influenza vaccines, identifying issues such as low vaccine effectiveness, reduced effectiveness among those who receive repeated vaccination, and issues related to egg adaptation during the manufacturing process. Epidemiological studies have also identified population level correlates of protection that can inform the design and development of next generation influenza vaccines. Going forward, there is an enduring need for epidemiological studies to continue advancing knowledge of correlates of protection and the development of immunity, to evaluate and monitor the effectiveness of next generation influenza vaccines, and to inform recommendations for their use. PMID- 29587414 TI - Identification of Blueberry miRNAs and Their Targets Based on High-Throughput Sequencing and Degradome Analyses. AB - miRNAs are important regulators of plant gene expression. To better characterize their functions, we applied high-throughput sequencing and degradome analyses to investigate three blueberry (Vaccinium ashei) tissues. A total of 127 known and 101 novel miRNAs were identified. Moreover, 141 targets for 42 known and 19 novel miRNAs were experimentally validated by degradome sequencing. A functional analysis of these miRNA targets revealed they were associated with diverse biological activities and several pathways, e.g., anthocyanin biosynthesis and cytokinin signal transduction. The data presented herein expand our understanding of the regulation of blueberry miRNAs during floral and fruit development stages. They may also provide new insights into the roles of miRNAs during anthocyanin biosynthesis in blueberry fruits. PMID- 29587413 TI - Multifaced Roles of the alphavbeta3 Integrin in Ehlers-Danlos and Arterial Tortuosity Syndromes' Dermal Fibroblasts. AB - The alphavbeta3 integrin, an endothelial cells' receptor-binding fibronectin (FN) in the extracellular matrix (ECM) of blood vessels, regulates ECM remodeling during migration, invasion, angiogenesis, wound healing and inflammation, and is also involved in the epithelial mesenchymal transition. In vitro-grown human control fibroblasts organize a fibrillar network of FN, which is preferentially bound on the entire cell surface to its canonical alpha5beta1 integrin receptor, whereas the alphavbeta3 integrin is present only in rare patches in focal contacts. We report on the preferential recruitment of the alphavbeta3 integrin, due to the lack of FN-ECM and its canonical integrin receptor, in dermal fibroblasts from Ehlers-Danlos syndromes (EDS) and arterial tortuosity syndrome (ATS), which are rare multisystem connective tissue disorders. We review our previous findings that unraveled different biological mechanisms elicited by the alphavbeta3 integrin in fibroblasts derived from patients affected with classical (cEDS), vascular (vEDS), hypermobile EDS (hEDS), hypermobility spectrum disorders (HSD), and ATS. In cEDS and vEDS, respectively, due to defective type V and type III collagens, alphavbeta3 rescues patients' fibroblasts from anoikis through a paxillin-p60Src-mediated cross-talk with the EGF receptor. In hEDS and HSD, without a defined molecular basis, the alphavbeta3 integrin transduces to the ILK Snail1-axis inducing a fibroblast-to-myofibroblast-transition. In ATS cells, the deficiency of the dehydroascorbic acid transporter GLUT10 leads to redox imbalance, ECM disarray together with the activation of a non-canonical alphavbeta3 integrin-TGFBRII signaling, involving p125FAK/p60Src/p38MAPK. The characterization of these different biological functions triggered by alphavbeta3 provides insights into the multifaced nature of this integrin, at least in cultured dermal fibroblasts, offering future perspectives for research in this field. PMID- 29587416 TI - Knocking down Insulin Receptor in Pancreatic Beta Cell lines with Lentiviral Small Hairpin RNA Reduces Glucose-Stimulated Insulin Secretion via Decreasing the Gene Expression of Insulin, GLUT2 and Pdx1. AB - Type 2 diabetes (T2D) is a metabolic disorder characterized by beta cell dysfunction and insulin resistance in fat, muscle and liver cells. Recent studies have shown that the development of insulin resistance in pancreatic beta cell lines may contribute to beta cell dysfunction in T2D. However, there still is a lack of detailed investigations regarding the mechanisms by which insulin deficiency may contribute in diabetes. In this study, we firstly established a stable insulin receptor knockdown cell line in pancreatic beta cells INS-1 (InsRbetaKD cells) using anti InsRbeta small hairpin RNA (InsRbeta-shRNA) encoded by lentiviral vectors. The resultant InsRbetaKD cells demonstrated a significantly reduced expression of InsRbeta as determined by real-time PCR and Western blotting analyses. Upon removing glucose from the medium, these cells exhibited a significant decrease in insulin gene expression and protein secretion in response to 20 mM glucose stimulation. In accordance with this insulin reduction, the glucose uptake efficiency as indicated by a 3[H]-2-deoxy-d-glucose assay also decreased. Furthermore, InsRbetaKD cells showed a dramatic decrease in glucose transporter 2 (GLUT2, encoded by SLC2A2) and pancreatic duodenal homeobox (Pdx1) mRNA expression compared to the controls. These data collectively suggest that pancreatic beta cell insulin resistance contributes to the development of beta cell dysfunction by impairing pancreatic beta cell glucose sensation through the Pdx1- GLUT2 pathway. InsRbetaKD cells provide a good model to further investigate the mechanism of beta-cell dysfunction in T2D. PMID- 29587417 TI - Role of the Hypothalamic-Pituitary-Adrenal Axis in Health and Disease.

PMID- 29587415 TI - The Sealing Zone in Osteoclasts: A Self-Organized Structure on the Bone. AB - Osteoclasts form a specialized cell-matrix adhesion structure, known as the "sealing zone", during bone resorption. The sealing zone is a dynamic actin-rich structure that defines the resorption area of the bone. The detailed dynamics and fine structure of the sealing zone have been elusive. Osteoclasts plated on glass do not form a sealing zone, but generate a separate supra-molecular structure called the "podosome belt". Podosomes are integrin-based adhesion complexes involved in matrix adhesion, cell migration, matrix degradation, and mechanosensing. Invadopodia, podosome-like protrusions in cancer cells, are involved in cell invasion into other tissues by promoting matrix degradation. Both podosomes and invadopodia exhibit actin pattern transitions during maturation. We previously found that Arp2/3-dependent actin flow occurs in all observed assembly patterns of podosomes in osteoclasts on glass. It is known that the actin wave in Dictyostelium cells exhibits a similar pattern transition in its evolution. Because of significant advances in our understanding regarding the mechanism of podosomes/invadopodia formation over the last decade, we revisited the structure and function of the sealing zone in this review, highlighting the possible involvement of self-organized actin waves in the organogenesis of the sealing zone. PMID- 29587418 TI - Genome-Wide Identification, Expression, and Functional Analysis of the Sugar Transporter Gene Family in Cassava (Manihot esculenta). AB - The sugar transporter (STP) gene family encodes monosaccharide transporters that contain 12 transmembrane domains and belong to the major facilitator superfamily. STP genes play critical roles in monosaccharide distribution and participate in diverse plant metabolic processes. To investigate the potential roles of STPs in cassava (Manihot esculenta) tuber root growth, genome-wide identification and expression and functional analyses of the STP gene family were performed in this study. A total of 20 MeSTP genes (MeSTP1-20) containing the Sugar_tr conserved motifs were identified from the cassava genome, which could be further classified into four distinct groups in the phylogenetic tree. The expression profiles of the MeSTP genes explored using RNA-seq data showed that most of the MeSTP genes exhibited tissue-specific expression, and 15 out of 20 MeSTP genes were mainly expressed in the early storage root of cassava. qRT-PCR analysis further confirmed that most of the MeSTPs displayed higher expression in roots after 30 and 40 days of growth, suggesting that these genes may be involved in the early growth of tuber roots. Although all the MeSTP proteins exhibited plasma membrane localization, variations in monosaccharide transport activity were found through a complementation analysis in a yeast (Saccharomyces cerevisiae) mutant, defective in monosaccharide uptake. Among them, MeSTP2, MeSTP15, and MeSTP19 were able to efficiently complement the uptake of five monosaccharides in the yeast mutant, while MeSTP3 and MeSTP16 only grew on medium containing galactose, suggesting that these two MeSTP proteins are transporters specific for galactose. This study provides significant insights into the potential functions of MeSTPs in early tuber root growth, which possibly involves the regulation of monosaccharide distribution. PMID- 29587419 TI - Enhanced Sensitivity to Subphonemic Segments in Dyslexia: A New Instance of Allophonic Perception. AB - Although dyslexia can be individuated in many different ways, it has only three discernable sources: a visual deficit that affects the perception of letters, a phonological deficit that affects the perception of speech sounds, and an audio visual deficit that disturbs the association of letters with speech sounds. However, the very nature of each of these core deficits remains debatable. The phonological deficit in dyslexia, which is generally attributed to a deficit of phonological awareness, might result from a specific mode of speech perception characterized by the use of allophonic (i.e., subphonemic) units. Here we will summarize the available evidence and present new data in support of the "allophonic theory" of dyslexia. Previous studies have shown that the dyslexia deficit in the categorical perception of phonemic features (e.g., the voicing contrast between /t/ and /d/) is due to the enhanced sensitivity to allophonic features (e.g., the difference between two variants of /d/). Another consequence of allophonic perception is that it should also give rise to an enhanced sensitivity to allophonic segments, such as those that take place within a consonant cluster. This latter prediction is validated by the data presented in this paper. PMID- 29587420 TI - Photophysical and Photocatalytic Properties of BiSnSbO6 under Visible Light Irradiation. AB - BiSnSbO6 with strong photocatalytic activity was first fabricated by a high temperature, solid-state sintering method. The resulting BiSnSbO6 was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS) and X-ray photoelectron spectroscopy (XPS). The results showed that BiSnSbO6, with a pyrochlore structure and a cubic crystal system by a space group Fd3m, was well crystallized. The lattice parameter or the band gap of BiSnSbO6 was 10.234594 A or 2.83 eV. Compared with N-doped TiO2, BiSnSbO6 showed higher photocatalytic activity in the degradation of benzotriazole and rhodamine B. The apparent first-order rate constant for BiSnSbO6 in the degradation of benzotriazole and rhodamine B was 0.0182 min-1 and 0.0147 min-1, respectively. On the basis of the scavenger experiment, during the photocatalytic process, the main active species were arranged in order of increasing photodegradation rate: *OH < *O2- < h+. The removal rate of benzotriazole or rhodamine B was approximately estimated to be 100% with BiSnSbO6 as a photocatalyst after 200 min visible-light irradiation. Plentiful CO2 produced by the experiment indicated that benzotriazole or rhodamine B was continuously mineralized during the photocatalytic process. Finally, the possible photodegradation pathways of benzotriazole and rhodamine B were deduced.

AB - In this paper, pure and Ag-doped SnO2 nanospheres were synthesized by hydrothermal method and characterized via X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), and X-ray photoelectron spectra (XPS), respectively. The gas sensing performance of the pure, 1 at.%, 3 at.%, and 5 at.% Ag-doped SnO2 sensing devices toward hydrogen (H2) were systematically evaluated. The results indicated that compared with pure SnO2 nanospheres, Ag-doped SnO2 nanospheres could not only decrease the optimum working temperature but also significantly improve H2 sensing such as higher gas response and faster response-recovery. Among all the samples, the 3 at.% Ag-doped SnO2 showed the highest response 39 to 100 MUL/L H2 at 300 degrees C. Moreover, its gas sensing mechanism was discussed, and the results will provide reference and theoretical guidance for the development of high-performance SnO2-based H2 sensing devices.

AB - The interfacial adhesion of recycled carbon fiber (CF) reinforced epoxy composite heated by microwave (MW) irradiation were investigated by changing the curing state of the epoxy resin. The recycled CF was recovered from the composite, which was prepared by vacuum-assisted resin transfer molding, by thermal degradation at 500 or 600 degrees C. Thermogravimetric analysis showed that the heating at 600 degrees C caused rough damage to the CF surface, whereas recycled CF recovered at 500 degrees C have few defects. The interfacial shear strength (IFSS) between recycled CF and epoxy resin was measured by a single-fiber fragmentation test. The test specimen was heated by MW after mixing the epoxy resin with a curing agent or pre-curing, in order to investigate the curing effects on the matrix resin. The IFSSs of the MW-irradiated samples were significantly varied by the curing state of the epoxy resin and the surface condition of recycled CF, resulting that they were 99.5 to 131.7% of oven heated samples Furthermore, rheological measurements showed that the viscosity and shrinking behaviors of epoxy resin were affected based on the curing state of epoxy resin before MW irradiation.

AB - Iodine is essential for thyroid hormones synthesis and normal neurodevelopment; however, ~60% of pregnant women do not meet the WHO (World Health Organization) recommended intake. Using a qualitative design, we explored the perceptions, awareness, and experiences of pregnancy nutrition, focusing on iodine. Women in the perinatal period (n = 48) were interviewed and filled in a food frequency questionnaire for iodine. Almost all participants achieved the recommended 150 MUg/day intake for non-pregnant adults (99%), but only 81% met the increased demands of pregnancy (250 MUg/day). Most were unaware of the importance, sources of iodine, and recommendations for iodine intake. Attitudes toward dairy products consumption were positive (e.g., helps with heartburn; easy to increase). Increased fish consumption was considered less achievable, with barriers around taste, smell, heartburn, and morning sickness. Community midwives were the main recognised provider of dietary advice. The dietary advice received focused most often on multivitamin supplements rather than food sources. Analysis highlighted a clear theme of commitment to change behaviour, motivated by pregnancy, with a desired focus on user-friendly documentation and continued involvement of the health services. The study highlights the importance of redirecting advice on dietary requirements in pregnancy and offers practical suggestions from women in the perinatal period as the main stakeholder group.

AB - A probabilistic method to remove the random telegraph signal (RTS) noise and to increase the signal level is proposed, and was verified by simulation based on measured real sensor noise. Although semi-photon-counting-level (SPCL) ultra-low noise complementary-metal-oxide-semiconductor (CMOS) image sensors (CISs) with high conversion gain pixels have emerged, they still suffer from huge RTS noise, which is inherent to the CISs. The proposed method utilizes a multi-aperture (MA) camera that is composed of multiple sets of an SPCL CIS and a moderately fast and compact imaging lens to emulate a very fast single lens. Due to the redundancy of the MA camera, the RTS noise is removed by the maximum likelihood estimation where noise characteristics are modeled by the probability density distribution. In the proposed method, the photon shot noise is also relatively reduced because of the averaging effect, where the pixel values of all the multiple apertures are considered. An extremely low-light condition that the maximum number of electrons per aperture was the only 2 e - was simulated. PSNRs of a test image for simple averaging, selective averaging (our previous method), and the proposed method were 11.92 dB, 11.61 dB, and 13.14 dB, respectively. The selective averaging, which can remove RTS noise, was worse than the simple averaging because it ignores the pixels with RTS noise and photon shot noise was less improved. The simulation results showed that the proposed method provided the best noise reduction performance. PMID- 29587425 TI - Radiofrequency Electromagnetic Radiation and Memory Performance: Sources of Uncertainty in Epidemiological Cohort Studies. AB - Uncertainty in experimental studies of exposure to radiation from mobile phones has in the past only been framed within the context of statistical variability. It is now becoming more apparent to researchers that epistemic or reducible uncertainties can also affect the total error in results. These uncertainties are derived from a wide range of sources including human error, such as data transcription, model structure, measurement and linguistic errors in communication. The issue of epistemic uncertainty is reviewed and interpreted in the context of the MoRPhEUS, ExPOSURE and HERMES cohort studies which investigate the effect of radiofrequency electromagnetic radiation from mobile phones on memory performance. Research into this field has found inconsistent results due to limitations from a range of epistemic sources. Potential analytic approaches are suggested based on quantification of epistemic error using Monte Carlo simulation. It is recommended that future studies investigating the relationship between radiofrequency electromagnetic radiation and memory performance pay more attention to treatment of epistemic uncertainties as well as further research into improving exposure assessment. Use of directed acyclic graphs is also encouraged to display the assumed covariate relationship. PMID- 29587426 TI - Exploring Geographic Variation of Mental Health Risk and Service Utilization of Doctors and Hospitals in Toronto: A Shared Component Spatial Modeling Approach. AB - Mental Health has been known to vary geographically. Different rates of utilization of mental health services in local areas reflect geographic variation of mental health and complexity of health care. Variations and inequalities in how the health care system addresses risks are two critical issues for addressing population mental health. This study examines these issues by analyzing the utilization of mental health services in Toronto at the neighbourhood level. We adopted a shared component spatial modeling approach that allows simultaneous analysis of two main health service utilizations: doctor visits and hospitalizations related to mental health conditions. Our results reflect a geographic variation of both types of mental health service utilization across neighbourhoods in Toronto. We identified hot and cold spots of mental health risks that are common to both or specific to only one type of health service utilization. Based on the evidence found, we discuss intervention strategies, focusing on the hotspots and provision of health services about doctors and hospitals, to improve mental health for the neighbourhoods. Limitations of the study and further research directions are also discussed. PMID- 29587427 TI - Surface Modification of Ti-35Nb-10Ta-1.5Fe by the Double Acid-Etching Process. AB - Surface topography and composition influence the osteoblastic proliferation and osseointegration rates, which favor the biomechanical stability of bone anchoring and implants. In recent years, beta titanium alloys have been developed, and are composed of biocompatible elements, have low elastic modulus, high corrosion resistance, and mechanical properties to improve the long performance behavior of biomaterials. In the present research, the influence of the acid-etching process was studied in Ti6Al4V ELI and Ti35Nb10Ta1.5Fe. Samples were etched in a two-step acid treatment. Surface roughness parameters were quantified under a confocal microscope, topography was studied by scanning electron microscopy, and surface composition was analyzed with energy dispersive X-ray spectroscopy. The results revealed that the two-step acid treatment changes the topography of the beta alloy, increases the surface area, and changes the chemical composition of the surface. Two differentiated regions were identified in the Ti35Nb10Ta1.5Fe alloy after the acid-etching process: The alpha + beta region with higher values of mean roughness due to the lower chemical resistance of this region; and the beta region with lower values of roughness parameters. PMID- 29587430 TI - Structure and Chemical Bonding of the Li-Doped Polar Intermetallic RE2In1-xLixGe2 (RE = La, Nd, Sm, Gd; x = 0.13, 0.28, 0.43, 0.53) System. AB - Four polar intermetallic compounds belonging to the RE2In1-xLixGe2 (RE = La, Nd, Sm, Gd; x = 0.13(1), 0.28(1), 0.43(1), 0.53(1)) system have been synthesized by the traditional solid-state reaction method, and their crystal structures have been characterized by single-crystal X-ray diffraction (SXRD) analyses. The isotypic crystal structures of four title compounds adopt the Mo2FeB2-type structure having the tetragonal space group P4/mbm (Z = 2, Pearson code tP40) with three crystallographically independent atomic sites and can be simply described as a pile of the identical 2-dimensioanl (2D) RE2In1-xLixGe2 slabs stacked along the c-axis direction. The substituting Li atom shows a particular site preference for replacing In at the Wyckoff 2a site rather than Ge at the Wyckoff 4g in this crystal structure. As the size of a used rare-earth metal decreases from La3+ to Gd3+ throughout the title system, the Ge-Ge and Ge-In/Li bond distances, both of which consist of the 2D anionic Ge2(In/Li) layer, gradually decrease resulting in the reduction of a unit cell volume. A series of theoretical investigations has been performed using a hypothetical structure model Gd2In0.5Li0.5Ge2 by tight-binding linear muffin-tin orbital (TB-LMTO) method. The resultant densities of states (DOS) value at the Fermi level (EF) suggests a metallic conductivity for this particular composition, and this calculation result is in a good agreement with the formal charge distribution assigning two extra valence electrons for a metal-metal bond in the conduction band. The thorough analyses of six crystal orbital Hamilton population (COHP) curves representing various interatomic interactions and an electron localization function (ELF) diagram indicating the locations of paired-electron densities are also provided in this article. PMID- 29587431 TI - UHPLC-MS/MS Quantification Combined with Chemometrics for Comparative Analysis of Different Batches of Raw, Wine-Processed, and Salt-Processed Radix Achyranthis Bidentatae. AB - An accurate and reliable method using ultra-high performance liquid chromatography combined with triple quadrupole tandem mass spectrometry (UHPLC MS/MS) was established for simultaneous quantification of five major bioactive analytes in raw, wine-processed, and salt-processed Radix Achyranthis bidentatae (RAB). The results showed that this method exhibited desirable sensitivity, precision, stability, and repeatability. The overall intra-day and inter-day variations (RSD) were in the range of 1.57-2.46 and 1.51-3.00%, respectively. The overall recoveries were 98.58-101.48% with a relative standard deviation (RSD) of 0.01-1.86%. In addition, the developed approach was applied to 21 batches of raw, wine-processed, and salt-processed samples of RAB. Hierarchical clustering analysis (HCA), principal component analysis (PCA), heat map, and boxplot analysis were performed to evaluate the quality of raw, wine-processed, and salt processed RAB collected from different regions. The chemometrics combined with the quantitative analysis based on UHPLC-MS/MS results indicated that the content of five analytes increased significantly in processed RAB compared to raw RAB. PMID- 29587429 TI - Plant-Derived Anticancer Agents: Lessons from the Pharmacology of Geniposide and Its Aglycone, Genipin. AB - For centuries, plants have been exploited by mankind as sources of numerous cancer chemotherapeutic agents. Good examples of anticancer compounds of clinical significance today include the taxanes (e.g., taxol), vincristine, vinblastine, and the podophyllotoxin analogues that all trace their origin to higher plants. While all these drugs, along with the various other available therapeutic options, brought some relief in cancer management, a real breakthrough or cure has not yet been achieved. This critical review is a reflection on the lessons learnt from decades of research on the iridoid glycoside geniposide and its aglycone, genipin, which are currently used as gold standard reference compounds in cancer studies. Their effects on tumour development (carcinogenesis), cancer cell survival, and death, with particular emphasis on their mechanisms of actions, are discussed. Particular attention is also given to mechanisms related to the dual pro-oxidant and antioxidant effects of these compounds, the mitochondrial mechanism of cancer cell killing through reactive oxygen species (ROS), including that generated through the uncoupling protein-2 (UCP-2), the inflammatory mechanism, and cell cycle regulation. The implications of various studies for the evaluation of glycosidic and aglycone forms of natural products in vitro and in vivo through pharmacokinetic scrutiny are also addressed. PMID- 29587428 TI - NF-kappaB Activation in Lymphoid Malignancies: Genetics, Signaling, and Targeted Therapy. AB - The NF-kappaB transcription factor family plays a crucial role in lymphocyte proliferation and survival. Consequently, aberrant NF-kappaB activation has been described in a variety of lymphoid malignancies, including diffuse large B-cell lymphoma, Hodgkin lymphoma, and adult T-cell leukemia. Several factors, such as persistent infections (e.g., with Helicobacter pylori), the pro-inflammatory microenvironment of the cancer, self-reactive immune receptors as well as genetic lesions altering the function of key signaling effectors, contribute to constitutive NF-kappaB activity in these malignancies. In this review, we will discuss the molecular consequences of recurrent genetic lesions affecting key regulators of NF-kappaB signaling. We will particularly focus on the oncogenic mechanisms by which these alterations drive deregulated NF-kappaB activity and thus promote the growth and survival of the malignant cells. As the concept of a targeted therapy based on the mutational status of the malignancy has been supported by several recent preclinical and clinical studies, further insight in the function of NF-kappaB modulators and in the molecular mechanisms governing aberrant NF-kappaB activation observed in lymphoid malignancies might lead to the development of additional treatment strategies and thus improve lymphoma therapy. PMID- 29587432 TI - Classification Accuracy of a Wearable Activity Tracker for Assessing Sedentary Behavior and Physical Activity in 3-5-Year-Old Children. AB - This study examined the accuracy of the Fitbit activity tracker (FF) for quantifying sedentary behavior (SB) and varying intensities of physical activity (PA) in 3-5-year-old children. Twenty-eight healthy preschool-aged children (Girls: 46%, Mean age: 4.8 +/- 1.0 years) wore the FF and were directly observed while performing a set of various unstructured and structured free-living activities from sedentary to vigorous intensity. The classification accuracy of the FF for measuring SB, light PA (LPA), moderate-to-vigorous PA (MVPA), and total PA (TPA) was examined calculating Pearson correlation coefficients (r), mean absolute percent error (MAPE), Cohen's kappa (k), sensitivity (Se), specificity (Sp), and area under the receiver operating curve (ROC-AUC). The classification accuracies of the FF (ROC-AUC) were 0.92, 0.63, 0.77 and 0.92 for SB, LPA, MVPA and TPA, respectively. Similarly, values of kappa, Se, Sp and percentage of correct classification were consistently high for SB and TPA, but low for LPA and MVPA. The FF demonstrated excellent classification accuracy for assessing SB and TPA, but lower accuracy for classifying LPA and MVPA. Our findings suggest that the FF should be considered as a valid instrument for assessing time spent sedentary and overall physical activity in preschool-aged children. PMID- 29587433 TI - What Persons with Chronic Health Conditions Need to Maintain or Return to Work Results of an Online-Survey in Seven European Countries. AB - Chronic health conditions represent the major share of the disease burden in Europe and have a significant impact on work. This study aims to: (1) identify factors that have a negative or positive impact on the work lives of persons with chronic health conditions; (2) explore the needs of these persons to maintain a job or return to work and (3) compare these results with respect to these persons' occupational status. An online survey was performed in seven European countries. Open-ended survey questions were analyzed using qualitative methods. In total, 487 participants with six chronic health conditions participated. The majority of participants named work-related aspects (such as career development, stress at the workplace, work structure and schedule as well as workload), support of others and attitudes of others as being the factors positively and negatively impact their work lives the most. Our study shed light on the importance of changing the attitudes of supervisors and co-workers to counteract stigmatization of persons with chronic health conditions in the workplace. In conclusion, this study provides a basis for developing new strategies of integration and reintegration at work for persons with chronic health conditions in European countries. PMID- 29587434 TI - Qualitative and Quantitative Analysis of Polyphenols in Lamiaceae Plants-A Review. AB - Lamiaceae species are promising potential sources of natural antioxidants, owing to their high polyphenol content. In addition, increasing scientific and epidemiological evidence have associated consumption of foods rich in polyphenols with health benefits such as decreased risk of cardiovascular diseases mediated through anti-inflammatory effects. The complex and diverse nature of polyphenols and the huge variation in their levels in commonly consumed herbs make their analysis challenging. Innovative robust analytical tools are constantly developing to meet these challenges. In this review, we present advances in the state of the art for the identification and quantification of polyphenols in Lamiaceae species. Novel chromatographic techniques that have been employed in the past decades are discussed, ranging from ultra-high-pressure liquid chromatography to hyphenated spectroscopic methods, whereas performance characteristics such as selectivity and specificity are also summarized. PMID- 29587435 TI - Non-Pleiotropic Coupling of Daily and Seasonal Temporal Isolation in the European Corn Borer. AB - Speciation often involves the coupling of multiple isolating barriers to produce reproductive isolation, but how coupling is generated among different premating barriers is unknown. We measure the degree of coupling between the daily mating time and seasonal mating time between strains of European corn borer (Ostrinia nubilalis) and evaluate the hypothesis that the coupling of different forms of allochrony is due to a shared genetic architecture, involving genes with pleiotropic effects on both timing phenotypes. We measure differences in gene expression at peak mating times and compare these genes to previously identified candidates that are associated with changes in seasonal mating time between the corn borer strains. We find that the E strain, which mates earlier in the season, also mates 2.7 h earlier in the night than the Z strain. Earlier daily mating is correlated with the differences in expression of the circadian clock genes cycle, slimb, and vrille. However, different circadian clock genes associate with daily and seasonal timing, suggesting that the coupling of timing traits is maintained by natural selection rather than pleiotropy. Juvenile hormone gene expression was associated with both types of timing, suggesting that circadian genes activate common downstream modules that may impose constraint on future evolution of these traits. PMID- 29587437 TI - Research on Strong Clutter Suppression for Gaofen-3 Dual-Channel SAR/GMTI. AB - In spaceborne synthetic aperture radar (SAR), moving targets are almost buried in ground clutter due to the wide clutter Doppler spectrum and the restricted pulse repetition frequency (PRF), which increases the difficulty of moving target detection. Clutter suppression is one of the key issues in the spaceborne SAR moving target indicator operation. In this paper, we describe the clutter suppression principle and analyze the influence of amplitude and phase error on clutter suppression. In the following, a novel dual-channel SAR clutter suppression algorithm is proposed, which is suitable for the Gaofen-3(GF-3) SAR sensor. The proposed algorithm consists of three technique steps, namely adaptive two-dimensional (2D) channel calibration, refined amplitude error correction and refined phase error correction. After channel error is corrected by these procedures, the clutter component, especially a strong clutter component, can be well suppressed. The validity of the proposed algorithm is verified by GF-3 SAR real data which demonstrates the ground moving-target indication (GMTI) capability of GF-3 SAR sensor. PMID- 29587436 TI - Harnessing the Power of T Cells: The Promising Hope for a Universal Influenza Vaccine. AB - Next-generation vaccines that utilize T cells could potentially overcome the limitations of current influenza vaccines that rely on antibodies to provide narrow subtype-specific protection and are prone to antigenic mismatch with circulating strains. Evidence from animal models shows that T cells can provide heterosubtypic protection and are crucial for immune control of influenza virus infections. This has provided hope for the design of a universal vaccine able to prime against diverse influenza virus strains and subtypes. However, multiple hurdles exist for the realisation of a universal T cell vaccine. Overall primary concerns are: extrapolating human clinical studies, seeding durable effective T cell resident memory (Trm), population human leucocyte antigen (HLA) coverage, and the potential for T cell-mediated immune escape. Further comprehensive human clinical data is needed during natural infection to validate the protective role T cells play during infection in the absence of antibodies. Furthermore, fundamental questions still exist regarding the site, longevity and duration, quantity, and phenotype of T cells needed for optimal protection. Standardised experimental methods, and eventually simplified commercial assays, to assess peripheral influenza-specific T cell responses are needed for larger-scale clinical studies of T cells as a correlate of protection against influenza infection. The design and implementation of a T cell-inducing vaccine will require a consensus on the level of protection acceptable in the community, which may not provide sterilizing immunity but could protect the individual from severe disease, reduce the length of infection, and potentially reduce transmission in the community. Therefore, increasing the standard of care potentially offered by T cell vaccines should be considered in the context of pandemic preparedness and zoonotic infections, and in combination with improved antibody vaccine targeting methods. Current pandemic vaccine preparedness measures and ongoing clinical trials under-utilise T cell-inducing vaccines, reflecting the myriad questions that remain about how, when, where, and which T cells are needed to fight influenza virus infection. This review aims to bring together basic fundamentals of T cell biology with human clinical data, which need to be considered for the implementation of a universal vaccine against influenza that harnesses the power of T cells. PMID- 29587438 TI - Does Vitamin D Deficiency Affect the Immunogenic Responses to Influenza Vaccination? A Systematic Review and Meta-Analysis. AB - Influenza virus infection is a major global public health problem, and the efficacy of influenza vaccination is not satisfactory. Vitamin D is involved in many immune-mediated inflammatory processes. The impact of vitamin D levels on the immunogenic response to influenza vaccination is not clear. We performed a comprehensive literature search and systematic review of studies that investigated vitamin D and influenza vaccination. Data pertaining to study population, vaccine components, vitamin D levels, and immunogenic response were analyzed. Nine studies, with a combined study population of 2367 patients, were included in the systematic review. Four studies were included in the meta analysis to investigate the influence of vitamin D deficiency (VDD) on the seroprotection (SP) rates and seroconversion (SC) rates following influenza vaccination. We found no significant association between vitamin D level and the immunogenic response to influenza vaccination. However, strain-specific differences may exist. We observed lower SP rates of influenza A virus subtype H3N2 (A/H3N2) and B strain in VDD patients than patients with normal vitamin D levels (A/H3N2: 71.8% vs. 80.1%, odds ratio (OR): 0.63, 95% confidence interval (CI): 0.43-0.91, p = 0.01; B strain: 69.6% vs. 76.4%, OR: 0.68, 95% CI: 0.5-0.93, p = 0.01). However, the SP rates of A/H1N1 and SC rates of all three strains were not significantly different in VDD and control groups. In conclusion, no association was observed between VDD and immunogenic response to influenza vaccination. PMID- 29587439 TI - NF2/Merlin Inactivation and Potential Therapeutic Targets in Mesothelioma. AB - The neurofibromatosis type 2 (NF2) gene encodes merlin, a tumor suppressor protein frequently inactivated in schwannoma, meningioma, and malignant mesothelioma (MM). The sequence of merlin is similar to that of ezrin/radixin/moesin (ERM) proteins which crosslink actin with the plasma membrane, suggesting that merlin plays a role in transducing extracellular signals to the actin cytoskeleton. Merlin adopts a distinct closed conformation defined by specific intramolecular interactions and regulates diverse cellular events such as transcription, translation, ubiquitination, and miRNA biosynthesis, many of which are mediated through Hippo and mTOR signaling, which are known to be closely involved in cancer development. MM is a very aggressive tumor associated with asbestos exposure, and genetic alterations in NF2 that abrogate merlin's functional activity are found in about 40% of MMs, indicating the importance of NF2 inactivation in MM development and progression. In this review, we summarize the current knowledge of molecular events triggered by NF2/merlin inactivation, which lead to the development of mesothelioma and other cancers, and discuss potential therapeutic targets in merlin-deficient mesotheliomas. PMID- 29587440 TI - 7-Acetylsinumaximol B Induces Apoptosis and Autophagy in Human Gastric Carcinoma Cells through Mitochondria Dysfunction and Activation of the PERK/eIF2alpha/ATF4/CHOP Signaling Pathway. AB - The 7-Acetylsinumaximol B (7-AB), a bioactive cembranoid, was originally discovered from aquaculture soft coral Sinularia sandensis. The current study investigated the anti-proliferative property of 7-AB towards the NCI-N87 human gastric cancer cell line. An MTT cell proliferative assay was applied to evaluate cell survival, and immunofluorescence staining and western blotting were employed to analyze the effects of 7-AB on autophagy and apoptosis. Our results showed that 7-AB exerted a concentration-dependent anti-proliferative effect on NCI-N87 cells, and fluorescence staining indicated that the effect was due to the apoptosis induced by 7-AB. In addition, the 7-AB-induced anti-proliferation towards NCI-N87 cells was associated with the release of cytochrome c from mitochondria, activation of pro-apoptotic proteins (such as caspase-3/-9, Bax and Bad), and inhibition of anti-apoptotic proteins (Bcl-2, Bcl-xL, and Mcl-1). The 7 AB treatment also triggered endoplasmic reticulum (ER) stress, leading to activation of the PERK/elF2alpha/ATF4/CHOP apoptotic pathway. Furthermore, 7-AB initiated autophagy in NCI-N87 cells and induced the expression of autophagy related proteins, including Atg3, Atg5, Atg7, Atg12, LC3-I, and LC3-II. Taken together, our findings suggested that 7-AB has the potential to be further developed as a useful anti-cancer or adjuvant agent for the treatment of human gastric cancer. PMID- 29587441 TI - Physical Activity Environment and Japanese Adults' Body Mass Index. AB - Evidence about the impacts of the physical activity environment on adults' weight in the context of Asian countries is scarce. Likewise, no study exists in Asia examining whether Walk Score(r)-a free online walkability tool-is related to obesity. This study aimed to examine associations between multiple physical activity environment measures and Walk Score(r) ratings with Japanese adults' body mass index (BMI). Data from 1073 adults in the Healthy Built Environment in Japan study were used. In 2011, participants reported their height and weight. Environmental attributes, including population density, intersection density, density of physical activity facilities, access to public transportation, and availability of sidewalks, were calculated using Geographic Information Systems. Walk Scores(r) ratings were obtained from the website. Multiple linear regression analysis was conducted to examine the association between each environmental attribute and BMI. Adjusting for covariates, all physical activity environmental attributes were negatively associated with BMI. Similarly, an increase of one standard deviation of Walk Score(r) was associated with a 0.29 (95% confidence interval (CI) of -0.49--0.09) decrease in BMI. An activity-friendly built environment was associated with lower adults' BMI in Japan. Investing in healthy community design may positively impact weight status in non-Western contexts. PMID- 29587442 TI - Junctional Adhesion Molecules (JAMs): The JAM-Integrin Connection. AB - Junctional adhesion molecules (JAMs) are cell surface adhesion receptors of the immunoglobulin superfamily. JAMs are involved in a variety of biological processes both in the adult organism but also during development. These include processes such as inflammation, angiogenesis, hemostasis, or epithelial barrier formation, but also developmental processes such as hematopoiesis, germ cell development, and development of the nervous system. Several of these functions of JAMs depend on a physical and functional interaction with integrins. The JAM - integrin interactions in trans regulate cell-cell adhesion, their interactions in cis regulate signaling processes originating at the cell surface. The JAM - integrin interaction can regulate the function of the JAM as well as the function of the integrin. Beyond the physical interaction with integrins, JAMs can regulate integrin function through intracellular signaling indicating an additional level of JAM - integrin cross-talk. In this review, we describe the various levels of the functional interplay between JAMs and integrins and the role of this interplay during different physiological processes. PMID- 29587444 TI - Microplastic Contamination of Wild and Captive Flathead Grey Mullet (Mugil cephalus). AB - A total of 60 flathead grey mullets were examined for microplastic ingestion. Thirty wild mullets were captured from the eastern coast of Hong Kong and 30 captive mullets were obtained from fish farms. Microplastic ingestion was detected in 60% of the wild mullets, with an average of 4.3 plastic items per mullet, while only 16.7% of captive mullets were found to have ingested microplastics, with an average of 0.2 items per mullet. The results suggested that wild mullets have a higher risk of microplastic ingestion than their captive counterparts. The most common plastic items were fibres that were green in colour and small in size (<2 mm). Polypropylene was the most common polymer (42%), followed by polyethylene (25%). In addition, the abundance of microplastics was positively correlated with larger body size among the mullets. PMID- 29587443 TI - The Horizon of a Therapy for Rare Genetic Diseases: A "Druggable" Future for Fibrodysplasia Ossificans Progressiva. AB - Fibrodysplasia ossificans progressiva (FOP) is a rare genetic condition characterized by progressive extra-skeletal ossification leading to cumulative and severe disability. FOP has an extremely variable and episodic course and can be induced by trauma, infections, iatrogenic harms, immunization or can occur in an unpredictable way, without any recognizable trigger. The causative gene is ACVR1, encoding the Alk-2 type I receptor for bone morphogenetic proteins (BMPs). The signaling is initiated by BMP binding to a receptor complex consisting of type I and II molecules and can proceed into the cell through two main pathways, a canonical, SMAD-dependent signaling and a p38-mediated cascade. Most FOP patients carry the recurrent R206H substitution in the receptor Glycine-Serine rich (GS) domain, whereas a few other mutations are responsible for a limited number of cases. Mutations cause a dysregulation of the downstream BMP-dependent pathway and make mutated ACVR1 responsive to a non-canonical ligand, Activin A. There is no etiologic treatment for FOP. However, many efforts are currently ongoing to find specific therapies targeting the receptor activity and the downstream aberrant pathway at different levels or targeting cellular components and/or processes that are important in modifying the local environment leading to bone neo-formation. PMID- 29587445 TI - Parental Nitrogen Transfer and Apparent Absence of N2 Fixation during Colony Foundation in Coptotermes formosanus Shiraki. AB - Colony foundation and early growth is a critical period in the life-cycle of a termite colony, as the initial family unit is resource limited. One such resource is nitrogen, which is essential for initial colony growth. This study examined the whole-colony nitrogen inventory during foundation and early growth of Coptotermes formosanus Shiraki colonies. It was hypothesized that termite colonies would go through an initial period of parental investment, representing a transfer of nitrogen to the first brood, and that once a functional worker caste was present, further provisioning in the form of intrinsic N2 fixation would occur. Our results showed that, when in nitrogen-poor rearing conditions, the king and queen initially transferred half of their nitrogen reserves to their first brood. However, the total nitrogen content in colonies did not increase over a 12 month period, despite the presence of functional workers. Furthermore, colonies did not increase their biomass beyond the initial parental investment. Together, these results imply that nitrogen acquisition in incipient C. formosanus colonies relies on environmental or dietary sources, rather than the putative fixation through symbiotic diazotrophs. PMID- 29587446 TI - Legionella spp. Risk Assessment in Recreational and Garden Areas of Hotels. AB - Several Travel-associated Legionnaires' disease (TALD) cases occur annually in Europe. Except from the most obvious sites (cooling towers and hot water systems), infections can also be associated with recreational, water feature, and garden areas of hotels. This argument is of great interest to better comprehend the colonization and to calculate the risk to human health of these sites. From July 2000-November 2017, the public health authorities of the Island of Crete (Greece) inspected 119 hotels associated with TALD, as reported through the European Legionnaires' Disease Surveillance Network. Five hundred and eighteen samples were collected from decorative fountain ponds, showers near pools and spas, swimming pools, spa pools, garden sprinklers, drip irrigation systems (reclaimed water) and soil. Of those, 67 (12.93%), originating from 43 (35.83%) hotels, tested positive for Legionella (Legionella pneumophila serogroups 1, 2, 3, 6, 7, 8, 13, 14, 15 and non-pneumophila species (L. anisa, L. erythra, L. taurinensis, L. birminghamensis, L. rubrilucens). A Relative Risk (R.R.) > 1 (p < 0.0001) was calculated for chlorine concentrations of less than 0.2 mg/L (R.R.: 54.78), star classification (<4) (R.R.: 4.75) and absence of Water Safety Plan implementation (R.R.: 3.96). High risk (>=104 CFU/L) was estimated for pool showers (16.42%), garden sprinklers (7.46%) and pool water (5.97%). PMID- 29587447 TI - Duration of Breastfeeding, but Not Timing of Solid Food, Reduces the Risk of Overweight and Obesity in Children Aged 24 to 36 Months: Findings from an Australian Cohort Study. AB - This study aimed to determine whether breastfeeding duration and the timing of solid food were independently associated with being overweight or obese in early childhood. Subjects were 953 children participating in the Study of Mothers and Infants Life Events Affecting Oral Health (SMILE) birth cohort study, based in Adelaide, Australia. Socio-demographic information and data on breastfeeding duration and age of introduction of solid food were collected at birth, 3, 4, 6, 12, and 24 months via mailed or online questionnaires completed by mothers. The weight and height of children were measured at a dental examination when children were aged between 24 and 36 months. Body mass index was calculated, and children were categorised into weight groups according to the World Health Organization growth standards. Multivariable logistic regression analysis was conducted, adjusting for maternal age at birth, education, socio-economic status, pre pregnancy weight, smoking in pregnancy, method of delivery, and child's birthweight. Risk of overweight/obesity was independently associated with maternal pre-pregnancy BMI, smoking in pregnancy, and birthweight. Children that were breastfed for 12 months or more had a significantly lower risk of being overweight/obese than those breastfed for less than 17 weeks (AOR 0.49; 95%CI 0.27, 0.90; p for trend =0.009). Age of introduction of solid food, however, was not associated with the risk of being overweight/obese at 24 to 36 months. This study provides further evidence of an inverse relationship between breastfeeding and risk of overweight/obesity, however, no association with the timing of solid food was detected.

AB - In this paper, we report the development, evaluation, and application of ultra small low-power wireless sensor nodes for advancing animal husbandry, as well as for innovation of medical technologies. A radio frequency identification (RFID) chip with hybrid interface and neglectable power consumption was introduced to enable switching of ON/OFF and measurement mode after implantation. A wireless power transmission system with a maximum efficiency of 70% and an access distance of up to 5 cm was developed to allow the sensor node to survive for a duration of several weeks from a few minutes' remote charge. The results of field tests using laboratory mice and a cow indicated the high accuracy of the collected biological data and bio-compatibility of the package. As a result of extensive application of the above technologies, a fully solid wireless pH sensor and a surgical navigation system using artificial magnetic field and a 3D MEMS magnetic sensor are introduced in this paper, and the preliminary experimental results are presented and discussed.

AB - When using distributed optical fiber sensors (DOFS) on reinforced concrete structures, a compromise must be achieved between the protection requirements and robustness of the sensor deployment and the accuracy of the measurements both in the uncracked and cracked stages and under loading, unloading and reloading processes. With this in mind the authors have carried out an experiment where polyimide-coated DOFS were installed on two concrete beams, both embedded in the rebar elements and also bonded to the concrete surface. The specimens were subjected to a three-point load test where after cracking, they are unloaded and reloaded again to assess the capability of the sensor when applied to a real loading scenarios in concrete structures. Rayleigh Optical Frequency Domain Reflectometry (OFDR) was used as the most suitable technique for crack detection in reinforced concrete elements. To verify the reliability and accuracy of the DOFS measurements, additional strain gauges were also installed at three locations along the rebar. The results show the feasibility of using a thin coated polyimide DOFS directly bonded on the reinforcing bar without the need of indention or mechanization. A proposal for a Spectral Shift Quality (SSQ) threshold is also obtained and proposed for future works when using polyimide coated DOFS bonded to rebars with cyanoacrylate adhesive.

AB - The Internet of Things (IoT) has received a lot of attention, especially in industrial scenarios. One of the typical applications is the intelligent mine, which actually constructs the Six-Hedge underground systems with IoT platforms. Based on a case study of the Six Systems in the underground metal mine, this paper summarizes the main challenges of industrial IoT from the aspects of heterogeneity in devices and resources, security, reliability, deployment and maintenance costs. Then, a novel resource service model for the industrial IoT applications based on Transparent Computing (TC) is presented, which supports centralized management of all resources including operating system (OS), programs and data on the server-side for the IoT devices, thus offering an effective, reliable, secure and cross-OS IoT service and reducing the costs of IoT system deployment and maintenance. The model has five layers: sensing layer, aggregation layer, network layer, service and storage layer and interface and management layer. We also present a detailed analysis on the system architecture and key technologies of the model. Finally, the efficiency of the model is shown by an experiment prototype system. PMID- 29587451 TI - Integrated Optoelectronic Position Sensor for Scanning Micromirrors. AB - Scanning micromirrors have been used in a wide range of areas, but many of them do not have position sensing built in, which significantly limits their application space. This paper reports an integrated optoelectronic position sensor (iOE-PS) that can measure the linear displacement and tilting angle of electrothermal MEMS (Micro-electromechanical Systems) scanning mirrors. The iOE PS integrates a laser diode and its driving circuits, a quadrant photo-detector (QPD) and its readout circuits, and a band-gap reference all on a single chip, and it has been fabricated in a standard 0.5 MUm CMOS (Complementary Metal Oxide Semiconductor) process. The footprint of the iOE-PS chip is 5 mm * 5 mm. Each quadrant of the QPD has a photosensitive area of 500 um * 500 um and the spacing between adjacent quadrants is 500 MUm. The iOE-PS chip is simply packaged underneath of an electrothermally-actuated MEMS mirror. Experimental results show that the iOE-PS has a linear response when the MEMS mirror plate moves vertically between 2.0 mm and 3.0 mm over the iOE-PS chip or scans from -5 to +5 degrees . Such MEMS scanning mirrors integrated with the iOE-PS can greatly reduce the complexity and cost of the MEMS mirrors-enabled modules and systems.

AB - Linum flavum hairy root lines were established from hypocotyl pieces using Agrobacterium rhizogenes strains LBA 9402 and ATCC 15834. Both strains were effective for transformation but induction of hairy root phenotype was more stable with strain ATCC 15834. Whereas similar accumulation patterns were observed in podophyllotoxin-related compounds (6-methoxy-podophyllotoxin, podophyllotoxin and deoxypodophyllotoxin), significant quantitative variations were noted between root lines. The influence of culture medium and various treatments (hormone, elicitation and precursor feeding) were evaluated. The highest accumulation was obtained in Gamborg B5 medium. Treatment with methyl jasmonate, and feeding using ferulic acid increased the accumulation of aryltetralin lignans. These results point to the use of hairy root culture lines of Linum flavum as potential sources for these valuable metabolites as an alternative, or as a complement to Podophyllum collected from wild stands.

AB - Patients after orthopic liver transplantation (OLT) are at risk of developing graft dysfunction. Sphingolipids (SL's) have been identified to play a pivotal role in the regulation of hepatocellular apoptosis, inflammation and immunity. We aimed to investigate the serum SL profile in a prospective real-world cohort of post-OLT patients. From October 2015 until July 2016, 149 well-characterized post OLT patients were analyzed. SL's were assessed in serum probes via Liquid Chromatography/Tandem Mass Spectrometry. Twenty-nine (20%) patients had a biopsy proven graft rejection with decreased C20-ceramide (Cer) (p = 0.042), C18 dihydroceramide (DHC) (p = 0.022) and C24DHC (p = 0.060) levels. Furthermore, C18DHC (p = 0.044) and C24DHC (p = 0.011) were significantly down-regulated in patients with ischemic type biliary lesions (ITBL; n = 15; 10%). One-hundred and thirty-three patients (89%) have so far received tacrolimus as the main immunosuppressive agent with observed elevations of C14Cer (p = 0.052), C18Cer (p = 0.049) and C18:1Cer (p = 0.024). Hepatocellular carcinoma (HCC) pre-OLT was associated with increases in C24:1Cer (p = 0.024) and C24:1DHC (p = 0.024). In this large prospective cross-sectional study of patients, post-OLT serum levels of (very-)long chain (dihydro-)ceramides associate with graft rejection, ITBL, tacrolimus intake and HCC pre-OLT. Hence, serum SL's may be indicative of graft complications. Further research is necessary to identify their diverse mechanistic role in regulating immunity and inflammation in patients post-OLT.

AB - The symposium, "Role of Nutrition in Alcoholic Liver Disease", was held at the European Society for Biomedical Research on Alcoholism Congress on 9 October 2017 in Crete, Greece. The goal of the symposium was to highlight recent advances and developments in the field of alcohol and nutrition. The symposium was focused on experimental and clinical aspects in relation to the role of different types of dietary nutrients and malnutrition in the pathogenesis of alcoholic liver disease (ALD). The following is a summary of key research presented at this session. The speakers discussed the role of dietary fats and carbohydrates in the development and progression of alcohol-induced multi-organ pathology in animal models of ALD, analyzed novel nutrition-related therapeutics (specifically, betaine and zinc) in the treatment of ALD, and addressed clinical relevance of malnutrition and nutrition support in ALD. This summary of the symposium will benefit junior and senior faculty currently investigating alcohol-induced organ pathology as well as undergraduate, graduate, and post-graduate students and fellows.

AB - Due to advances in telemedicine, mobile medical care, wearable health monitoring, and electronic skin, great efforts have been directed to non-invasive monitoring and treatment of disease. These processes generally involve disease detection from interstitial fluid (ISF) instead of blood, and transdermal drug delivery. However, the quantitative extraction of ISF and the level of drug absorption are greatly affected by the individual's skin permeability, which is closely related to the properties of the stratum corneum (SC). Therefore, measurement of SC impedance has been proposed as an appropriate way for assessing individual skin differences. In order to figure out the current status and research direction of human SC impedance detection, investigations regarding skin impedance measurement have been reviewed in this paper. Future directions are concluded after a review of impedance models, electrodes, measurement methods and systems, and their applications in treatment. It is believed that a well-matched skin impedance model and measurement method will be established for clinical and point-of care applications in the near future. PMID- 29587457 TI - An Experimental Study of a Micro-Projection Enabled Optical Terminal for Short Range Bidirectional Multi-Wavelength Visible Light Communications. AB - A micro-projection enabled short-range communication (SRC) approach using red-, green- and blue-based light-emitting diodes (RGB-LEDs) has experimentally demonstrated recently that micro-projection and high-speed data transmission can be performed simultaneously. In this research, a reconfigurable design of a polarization modulated image system based on the use of a Liquid Crystal on Silicon based Spatial Light Modulator (LCoS-based SLM) serving as a portable optical terminal capable of micro-projection and bidirectional multi-wavelength communications is proposed and experimentally demonstrated. For the proof of concept, the system performance was evaluated through a bidirectional communication link at a transmission distance over 0.65 m. In order to make the proposed communication system architecture compatible with the data modulation format of future possible wireless communication system, baseband modulation scheme, i.e., Non-Return-to-Zero On-Off-Keying (NRZ_OOK), M-ary Phase Shift Keying (M-PSK) and M-ary Quadrature Amplitude Modulation (M-QAM) were used to investigate the system transmission performance. The experimental results shown that an acceptable BER (satisfying the limitation of Forward Error Correction, FEC standard) and crosstalk can all be achieved in the bidirectional multi wavelength communication scenario.

AB - Seed imbibition under cold temperature is dangerous when dry seeds have relatively low water content. The aim of this study was to investigate germination of 20 lines/cultivars of narrow-leaf lupine at 7 degrees C (cold) and 13 degrees C (control) under the influence of smoke water and following seed hydropriming for 3 h at 20 degrees C. The efficacy of individual treatments was examined with regard to seed protection during low-temperature germination. Based on seed germination, vigour at cold was evaluated four days after sowing by means of hypocotyl length, the studied lines/cultivars were divided into three groups with low, high and very high germination rates. Germination vigour correlated with cell membrane permeability, dehydrogenase activity and abscisic acid (ABA) content and was analysed in the seeds one day after sowing. Gibberellin content did not correlate with germination vigour. The seeds of weakly germinating lines/cultivars had the highest cell permeability and ABA content as well as the lowest amylolytic activity at both studied temperatures. Additionally, the vigour of weakly germinating seeds at 7 degrees C correlated with dehydrogenase activity. Three-hour hydropriming was the most effective for seed germination under cold due to reduced cell membrane permeability and ABA level. Stimulating effects of smoke water on germination under cold could be explained by enhanced dehydrogenase activity. PMID- 29587460 TI - Analytical Method to Estimate the Complex Permittivity of Oil Samples. AB - In this paper, an analytical method to estimate the complex dielectric constant of liquids is presented. The method is based on the measurement of the transmission coefficient in an embedded microstrip line loaded with a complementary split ring resonator (CSRR), which is etched in the ground plane. From this response, the dielectric constant and loss tangent of the liquid under test (LUT) can be extracted, provided that the CSRR is surrounded by such LUT, and the liquid level extends beyond the region where the electromagnetic fields generated by the CSRR are present. For that purpose, a liquid container acting as a pool is added to the structure. The main advantage of this method, which is validated from the measurement of the complex dielectric constant of olive and castor oil, is that reference samples for calibration are not required. PMID- 29587458 TI - Towards an Integrative Understanding of tRNA Aminoacylation-Diet-Host-Gut Microbiome Interactions in Neurodegeneration. AB - Transgenic mice used for Alzheimer's disease (AD) preclinical experiments do not recapitulate the human disease. In our models, the dietary tryptophan metabolite tryptamine produced by human gut microbiome induces tryptophanyl-tRNA synthetase (TrpRS) deficiency with consequent neurodegeneration in cells and mice. Dietary supplements, antibiotics and certain drugs increase tryptamine content in vivo. TrpRS catalyzes tryptophan attachment to tRNAtrp at initial step of protein biosynthesis. Tryptamine that easily crosses the blood-brain barrier induces vasculopathies, neurodegeneration and cell death via TrpRS competitive inhibition. TrpRS inhibitor tryptophanol produced by gut microbiome also induces neurodegeneration. TrpRS inhibition by tryptamine and its metabolites preventing tryptophan incorporation into proteins lead to protein biosynthesis impairment. Tryptophan, a least amino acid in food and proteins that cannot be synthesized by humans competes with frequent amino acids for the transport from blood to brain. Tryptophan is a vulnerable amino acid, which can be easily lost to protein biosynthesis. Some proteins marking neurodegenerative pathology, such as tau lack tryptophan. TrpRS exists in cytoplasmic (WARS) and mitochondrial (WARS2) forms. Pathogenic gene variants of both forms cause TrpRS deficiency with consequent intellectual and motor disabilities in humans. The diminished tryptophan dependent protein biosynthesis in AD patients is a proof of our model-based disease concept.

AB - T-2 toxin is a secondary metabolite of some Fusarium species. It is well-known that this substance can harmfully impact living organisms. Among others, thanks to the ability of crossing the blood-brain barrier, T-2 toxin can affect the central nervous system. Mycotoxins mostly get into the organism through the digestive tract; therefore, first of all they have to break the intestinal barrier, wherein the important component is the enteric nervous system (ENS). However, knowledge about the impact of T-2 toxin on the ENS is rather scant. As a result of the influence of various physiological and pathological agents, ENS can undergo adaptive and reparative processes which manifest as changes in the immunoreactivity of perikaryons for neuronal active substances. So, the aim of the present investigation was to study how low doses of T-2 toxin affect vasoactive intestinal polypeptide-like immunoreactive (VIP-LI) nervous structures in the ENS of the porcine stomach and duodenum. Obtained results have shown that T-2 toxin causes an percentage increase of VIP-LI nerve cells and nerve fibers in every enteric plexus in both fragments of gastrointestinal tract studied. This shows that even low doses of T-2 toxin can have an influence on living organisms.

AB - Heating is a traditional method used in ginseng root processing, however, there aren't reports on differences resulting from baking and steaming. Moreover, ginseng flowers, with 5.06 times more total saponins than ginseng root, are not fully taken advantage of for their ginsenosides. Transformation mechanisms of ginsenosides in ginseng flowers upon baking and steaming were thus explored. HPLC using authentic standards of 20 ginsenosides and UPLC-QTOF-MS/MS were used to quantify and identify ginsenosides, respectively, in ginseng flowers baked or steamed at different temperatures and durations. Results show that baking and steaming caused a 3.2-fold increase in ginsenoside species existed in unheated ginseng flowers (20/64 ginsenosides) and transformation of a certain amount of polar ginsenosides into numerous less polar ginsenosides. Among the 20 ginsenosides with standards, polar ginsenosides were abundant in ginseng flowers baked or steamed at lower temperatures, whereas less polar ginsenosides occurred and were enriched at higher temperatures. Furthermore, the two types of heating treatments could generate mostly similar ginsenosides, but steaming was much efficient than baking in transforming polar- into less polar ginsenosides, with steaming at 120 degrees C being comparably equivalent to baking at 150 degrees C. Moreover, both the two heating methods triggered ginsenoside acetylation and thus caused formation of 16 acetylginsenosides. Finally, a new transformation mechanism concerning acetyl-ginsenosides formation was proposed. PMID- 29587463 TI - Study of Adsorption Mechanism of Congo Red on Graphene Oxide/PAMAM Nanocomposite. AB - Graphene oxide/poly(amidoamine) (GO/PAMAM) nanocomposite adsorbed high quantities of congo red (CR) anionic dye in 0.1 M NaCl solution, with the maximum adsorption capacity of 198 mg.g-1. The kinetics and thermodynamics of adsorption were investigated to elucidate the effects of pH, temperature, shaking rate, ionic strength, and contact time. Kinetic data were analyzed by the KASRA model and the KASRA, ISO, and pore-diffusion equations. Adsorption adsorption isotherms were studied by the ARIAN model and the Henry, Langmuir, and Temkin equations. It was shown that adsorption sites of GO/PAMAM at experimental conditions were phenolic hydroxyl groups of GO sheets and terminal amine groups of PAMAM dendrimer. Analysis of kinetic data indicated that amine sites were located on the surface, and that hydroxyl sites were placed in the pores of adsorbent. CR molecules interacted with the adsorption sites via hydrogen bonds. The molecules were adsorbed firstly on the amine sites, and then on the internal hydroxyl sites. Adsorption kinetic parameters indicated that the interaction of CR to the -NH3+ sites was the rate-controlling step of adsorption of CR on this site and adsorption activation energies calculated for different parts of this step. On the other hand, kinetic parameters showed that the intraparticle diffusion was the rate-controlling step during the interaction of CR molecules to -OH sites and activation energy of this step was not calculable. Finally, the used GO/PAMAM was completely regenerated by using ethylenediamine. PMID- 29587464 TI - Design and Processing of a Novel Chaos-Based Stepped Frequency Synthesized Wideband Radar Signal. AB - The linear stepped frequency and linear frequency shift keying (FSK) signal has been widely used in radar systems. However, such linear modulation signals suffer from the range-Doppler coupling that degrades radar multi-target resolution. Moreover, the fixed frequency-hopping or frequency-coded sequence can be easily predicted by the interception receiver in the electronic countermeasures (ECM) environments, which limits radar anti-jamming performance. In addition, the single FSK modulation reduces the radar low probability of intercept (LPI) performance, for it cannot achieve a large time-bandwidth product. To solve such problems, we propose a novel chaos-based stepped frequency (CSF) synthesized wideband signal in this paper. The signal introduces chaotic frequency hopping between the coherent stepped frequency pulses, and adopts a chaotic frequency shift keying (CFSK) and phase shift keying (PSK) composited coded modulation in a subpulse, called CSF-CFSK/PSK. Correspondingly, the processing method for the signal has been proposed. According to our theoretical analyses and the simulations, the proposed signal and processing method achieve better multi target resolution and LPI performance. Furthermore, flexible modulation is able to increase the robustness against identification of the interception receiver and improve the anti-jamming performance of the radar. PMID- 29587465 TI - MicroRNA-146a Deficiency Protects against Listeria monocytogenes Infection by Modulating the Gut Microbiota. AB - The gut microbiota and microRNAs play important roles in the defense against infection. However, the role of miR-146a in L. monocytogenes infection and gut microbiota remains unclear. We tried to determine whether miR-146a controlled L. monocytogenes infection by regulating the gut microbiota. Wild-type and miR-146a deficient mice or macrophages were used to characterize the impact of miR-146a on animal survival, cell death, bacterial clearance, and gut microbiota following L. monocytogenes challenge. We found that L. monocytogenes infection induced miR 146a expression both in vitro and in vivo. When compared to wild-type mice, miR 146a-deficient mice were more resistant to L. monocytogenes infection. MiR-146a deficiency in macrophages resulted in reduced invasion and intracellular survival of L. monocytogenes. High-throughput sequencing of 16S rRNA revealed that the gut microbiota composition differed between miR-146a-deficient and wild-type mice. Relative to wild-type mice, miR-146a-deficient mice had decreased levels of the Proteobacteria phylum, Prevotellaceae family, and Parasutterella genus, and significantly increased short-chain fatty acid producing bacteria, including the genera Alistipes, Blautia, Coprococcus_1, and Ruminococcus_1. Wild-type mice co housed with miR-146a-deficient mice had increased resistance to L. monocytogenes, indicating that miR-146a deficiency guides the gut microbiota to alleviate infection. Together, these results suggest that miR-146a deficiency protects against L. monocytogenes infection by regulating the gut microbiota. PMID- 29587467 TI - Sandwich-Type Nitrogen and Sulfur Codoped Graphene-Backboned Porous Carbon Coated Separator for High Performance Lithium-Sulfur Batteries. AB - Lithium-sulfur (Li-S) batteries have been identified as the greatest potential next- generation energy-storage systems because of the large theoretical energy density of 2600 Wh kg-1. However, its practical application on a massive scale is impeded by severe capacity loss resulted from the notorious polysulfides shuttle. Here, we first present a novel technique to synthesize sandwich-type nitrogen and sulfur codoped graphene-backboned porous carbon (NSGPC) to modify the commercial polypropylene separator in Li-S batteries. The as-synthesized NSGPC exhibits a unique micro/mesoporous carbon framework, large specific surface area (2439.0 m2 g-1), high pore volume (1.78 cm3 g-1), good conductivity, and in situ nitrogen (1.86 at %) and sulfur (5.26 at %) co-doping. Benefiting from the particular physical properties and chemical components of NSGPC, the resultant NSGPC-coated separator not only can facilitate rapid Li+ ions and electrons transfer, but also can restrict the dissolution of polysulfides to alleviate the shuttle effect by combining the physical absorption and strong chemical adsorption. As a result, Li S batteries with NSGPC-coated separator exhibit high initial reversible capacity (1208.6 mAh g-1 at 0.2 C), excellent rate capability (596.6 mAh g-1 at 5 C), and superior cycling stability (over 500 cycles at 2 C with 0.074% capacity decay each cycle). Propelling our easy-designed pure sulfur cathode to a extremely increased mass loading of 3.4 mg cm-2 (70 wt. % sulfur), the Li-S batteries with this functional composite separator exhibit a superior high initial capacity of 1171.7 mAh g-1, which is quite beneficial to commercialized applications. PMID- 29587469 TI - Coupling Vibration Analysis of Trapped-Energy Rectangular Quartz Resonators by Variational Formulation of Mindlin's Theory. AB - Mindlin's two-dimensional theory has been derived and applied to research on quartz resonators for a long time. However, most works have focused on vibrations varying only in two directions, including thickness direction, while the effect of other directions like the length or width direction is normally neglected. Besides, researchers often model quartz resonators as fully electroded plates because of the resulting simplicity. Since a real device is finite in all directions and is only centrally electroded, results obtained in such works cannot offer quantitative information on vibrations with enough accuracy. In this paper, a theoretical analysis of a rectangular trapped-energy resonator of AT-cut quartz is studied using the Ritz method, associated with the variational formulation of Mindlin's first-order equations. Frequency spectra and mode shapes of a real-scaled trapped-energy resonator, which is finite in all directions, are obtained with the consideration of mode couplings among thickness-shear mode, thickness-twist mode, and flexural mode. Results show the existence of an energy trapping and coupling phenomenon and are helpful for thorough and accurate understanding of quartz resonator vibrations. Detailed discussions on the effects of structural parameters on mode couplings and energy trapping are provided, and the results can helpfully guide the selection of aspect ratio, length/thickness ratio, and electrode inertia in device design. PMID- 29587466 TI - Chromosomal Instability in Hodgkin Lymphoma: An In-Depth Review and Perspectives. AB - The study of Hodgkin lymphoma (HL), with its unique microenvironment and long term follow-up, has provided exceptional insights into several areas of tumor biology. Findings in HL have not only improved our understanding of human carcinogenesis, but have also pioneered its translation into the clinics. HL is a successful paradigm of modern treatment strategies. Nonetheless, approximately 15 20% of patients with advanced stage HL still die following relapse or progressive disease and a similar proportion of patients are over-treated, leading to treatment-related late sequelae, including solid tumors and organ dysfunction. The malignant cells in HL are characterized by a highly altered genomic landscape with a wide spectrum of genomic alterations, including somatic mutations, copy number alterations, complex chromosomal rearrangements, and aneuploidy. Here, we review the chromosomal instability mechanisms in HL, starting with the cellular origin of neoplastic cells and the mechanisms supporting HL pathogenesis, focusing particularly on the role of the microenvironment, including the influence of viruses and macrophages on the induction of chromosomal instability in HL. We discuss the emerging possibilities to exploit these aberrations as prognostic biomarkers and guides for personalized patient management. PMID- 29587468 TI - Application of the P300 Event-Related Potential in the Diagnosis of Epilepsy Disorder: A Review. AB - Epilepsy is one of the most serious chronical neurological disorders, affecting more than 50 million people worldwide. It can be defined as a spectrum disorder, and patients with epilepsy possess abnormalities in cognitive functions. A number of factors can cause cognitive dysfunctions in epileptic syndromes, including etiology, the age of onset, type of seizure and severity, duration, and antiepileptic drugs. Event-related potentials (ERPs) are very useful clinical and research instruments to evaluate cognitive function in patients with neuropsychiatry disorders. Event-related potentials directly reflect cortical neuronal activity and provide a particular level of temporal resolution. Among various ERP components, the P300 is the most important component for assessing cognitive processes such as attention, working memory, and concentration. Numerous studies have reported the abnormalities in amplitude or latency of P300 component of ERP in epileptic patients, and these abnormalities are indicative of cognitive dysfunction. Therefore, the purpose of this review is to consolidate the existing literature in connection with the use of P300 in epileptic patients. PMID- 29587470 TI - Global Correlates of Cardiovascular Risk: A Comparison of 158 Countries. AB - The aim of this study was a large-scale ecological analysis of nutritional and other environmental factors potentially associated with the incidence of cardiovascular diseases (CVDs) in the global context. Indicators of CVDs from 158 countries were compared with the statistics of mean intake (supply) of 60 food items between 1993 and 2011, obesity rates, health expenditure and life expectancy. This comparison shows that the relationship between CVD indicators (raised blood pressure, CVD mortality, raised blood glucose) and independent variables in the global context is influenced by various factors, such as short life expectancy, religiously conditioned dietary customs, the imprecision of some statistics and undernutrition. However, regardless of the statistical method used, the results always show very similar trends and identify high carbohydrate consumption (mainly in the form of cereals and wheat, in particular) as the dietary factor most consistently associated with the risk of CVDs. These findings are in line with the changing view of the causes of CVDs. Because the statistics of raised blood glucose only include people using medications and do not reflect true prevalence that is independent of healthcare, more objective data on the prevalence of CVDs are needed to confirm these observed trends. PMID- 29587471 TI - Effects of Two Doses of Curry Prepared with Mixed Spices on Postprandial Ghrelin and Subjective Appetite Responses-A Randomized Controlled Crossover Trial. AB - Spices are known to provide orosensory stimulation that can potentially influence palatability, appetite, and energy balance. Previous studies with individual spices have shown divergent effects on appetite and energy intake measures. In a real-life context, however, several spices are consumed in combinations, as in various forms of curries. Therefore, we investigated changes in postprandial appetite and plasma ghrelin in response to the intake of two doses of curry prepared with mixed spices. The study was undertaken in healthy Chinese men, between 21 and 40 years of age and body mass index <=27.5 kg/m2. Appetite was measured using visual analogue scales (VAS) and plasma ghrelin was measured using multiplex assay. Compared with the control meal (Dose 0 Control (D0C), 0 g mixed spices), we found significantly greater suppression in 'hunger' (both p < 0.05, after Bonferroni adjustments) as well in 'desire to eat' (both p < 0.01) during the Dose 1 Curry (D1C, 6 g mixed spices) and Dose 2 Curry (D2C, 12 g mixed spices) intake. There were no differences, however, in plasma ghrelin or in other appetite measures such as in 'fullness' or in 'prospective eating' scores. Overall, the results of our study indicate greater inter-meal satiety due to mixed spices consumption, independent of any changes in plasma ghrelin response. PMID- 29587472 TI - 2D Analytical Model for the Directivity Prediction of Ultrasonic Contact Type Transducers in the Generation of Guided Waves. AB - In this paper, a novel 2D analytical model based on the Huygens's principle of wave propagation is proposed in order to predict the directivity patterns of contact type ultrasonic transducers in the generation of guided waves (GWs). The developed model is able to estimate the directivity patterns at any distance, at any excitation frequency and for any configuration and shape of the transducers with prior information of phase dispersive characteristics of the guided wave modes and the behavior of transducer. This, in turn, facilitates to choose the appropriate transducer or arrays of transducers, suitable guided wave modes and excitation frequency for the nondestructive testing (NDT) and structural health monitoring (SHM) applications. The model is demonstrated for P1-type macro-fiber composite (MFC) transducer glued on a 2 mm thick aluminum (Al) alloy plate. The directivity patterns of MFC transducer in the generation of fundamental guided Lamb modes (the S0 and A0) and shear horizontal mode (the SH0) are successfully obtained at 80 kHz, 5-period excitation signal. The results are verified using 3D finite element (FE) modelling and experimental investigation. The results obtained using the proposed model shows the good agreement with those obtained using numerical simulations and experimental analysis. The calculation time using the analytical model was significantly shorter as compared to the time spent in experimental analysis and FE numerical modelling.

AB - Despite notable progress, the fabrication of well-defined polypeptides via controlled ring-opening polymerization (ROP) of alpha-amino acid N carboxyanhydrides (NCAs) using convenient catalysts under mild conditions in a relatively short polymerization time is still challenging. Herein, an easily obtained catalyst system composed of zinc acetate and aniline was explored to mediate the fast ROP of gamma-benzyl-l-glutamate-N-carboxyanhydride (BLG-NCA) monomer, to produce poly(gamma-benzyl-l-glutamates) (PBLGs) with controllable molecular weights and narrow dispersity. Considering the excellent cooperative action of zinc acetate and a broad scope of aniline derivatives with different functional groups to control ROP of BLG-NCA, this method may offer a useful platform enabling the rapid generation of end-functionalized PBLG and block copolymers for numerous biomedical applications.

AB - OBJECTIVES: To investigate neurotoxic effect of bone cement (BC) on facial nerve by using electrophysiological and histopathological methods. METHODS: This study included 20 male albino Wistar rats, divided into four equal groups. Group A was designed as the control group, while group B was sham group. In the group C, BC solution was dropped onto the facial nerve trunks of rats and washed with physiological saline after 5 seconds. In the group D, BC solution was dropped onto the facial nerve trunks of rats and after allowing 5 minutes to dry, wounds were closed. Pre- and postoperative (on 4th week) evoked electromyography (EMG) measurements were done. For histopathological assessments, the rats were euthanized and tissue samples of facial nerve and surrounding areas were collected. RESULTS: According to the wave amplitude levels of evoked EMG, postoperative amplitude levels of group D were significantly decreased, compared to preoperative amplitude levels (P=0.043). We found no statistically significant difference in inflammation among the groups. In none of the groups, foreign body reaction and granulation tissue were not detected in any of the groups. In addition, degeneration in axon, myelin, or perineural nets was not detected in any of the groups. CONCLUSION: This study results suggest that BC has no direct toxicity on facial nerve, while it has indirect effects, by decreasing amplitude. Therefore, we conclude that direct contact of BC with nerve should be avoided, and the area should be cleaned by aspiration or washing with physiological saline in case of contact.

AB - OBJECTIVES: The aim of this multicenter registry study was to investigate the effectiveness of ventilation tube insertion and the microbiology of otitis media with effusion (OME) in children. This part I study was conducted to evaluate the microbiological profile of children with OME who needed ventilation tube insertion. METHODS: Patients <15 years old who were diagnosed as having OME and received ventilation tube insertion were prospectively enrolled in 16 tertiary hospitals from June 2014 to December 2016. After excluding patients with missing data, the data of 397 patients were analyzed among a total of 433 enrolled patients. The clinical symptoms, findings of the tympanic membrane, hearing level, and microbiological findings were collected. RESULTS: In 103 patients (25.9%), antibiotics were used within 3 weeks before surgery. Ventilation tube insertion was performed in a total of 710 ears (626 in both ears in 313 patients, 55 in the left ear only, and 29 in the right ear only). Culture of middle ear effusion was done in at least one ear in 221 patients (55.7%), and in a total of 346 ears. Only 46 ears (13.3%) showed positive results in middle ear effusion culture. Haemophilus influenzae (17.3%, followed by coagulase-negative Staphylococcus and Staphylococcus auricularis) was the most common bacteria detected. CONCLUSION: H. influenzae was the most commonly found bacteria in middle ear effusion. Relatively low rates of culture positivity were noted in middle ear effusion of patients with OME in Korea.

AB - Cholesteryl ester transfer protein (CETP) facilitates the transfer of cholesteryl esters (CEs) from antiatherogenic high-density lipoproteins to proatherogenic low density lipoproteins. Inhibition of CETP is therefore being pursued as a potential strategy to reduce cardiovascular risk. The crystal structure of CETP has revealed the existence of two neutral CEs and two charged phospholipids (PLs) in its hydrophobic tunnel. This is in direct contrast to the other lipid-binding proteins that contain only two bound lipids. Moreover, previous animal studies on mice showed no detectable PL-transfer activity of CETP. Thus, the role of bound PLs in CETP is completely unknown. Here, we employ molecular dynamics simulations and free-energy calculations to unravel the primary effects of bound PLs on CETP structure and dynamics and attempt to correlate the observed changes to its function. Our results suggest that the structure of CETP is elastic and can attain different conformations depending on the state of bound PLs. In solution, these PLs maintain CETP in a bent-untwisted conformation that can uphold neutral lipids in its core tunnel. Results also suggest that although both PLs complement each other in their action, the C-terminal PL (C-PL) imparts greater influence on CETP by virtue of its tighter binding. Our finding fits very well with the recent inhibitor-bound CETP crystal structure, where the inhibitor displaced the N terminal PL for binding to CETP's central domain without disrupting the binding of C-PL. We speculate that the observed increased flexibility of CETP in the absence of PLs could play a crucial role in its binding with lipoproteins and subsequent lipid-transfer activity. PMID- 29587477 TI - S- Cis Diene Conformation: A New Bathochromic Shift Strategy for Near-Infrared Fluorescence Switchable Dye and the Imaging Applications. AB - In this paper, we present a novel charge-free fluorescence-switchable near infrared (IR) dye based on merocyanine for target specific imaging. In contrast to the typical bathochromic shift approach by extending pi-conjugation, the bathochromic shift of our merocyanine dye to the near-IR region is due to an unusual S- cis diene conformer. This is the first example where a fluorescent dye adopts the stable S- cis conformation. In addition to the novel bathochromic shift mechanism, the dye exhibits fluorescence-switchable properties in response to polarity and viscosity. By incorporating a protein-specific ligand to the dye, the probes (for SNAP-tag and hCAII proteins) exhibited dramatic fluorescence increase (up to 300-fold) upon binding with its target protein. The large fluorescence enhancement, near-IR absorption/emission, and charge-free scaffold enabled no-wash and site-specific imaging of target proteins in living cells and in vivo with minimum background fluorescence. We believe that our unconventional approach for a near-IR dye with the S- cis diene conformation can lead to new strategies for the design of near-IR dyes. PMID- 29587478 TI - Celecoxib Conjugated Fluorescent Probe for Identification and Discrimination of Cyclooxygenase-2 Enzyme in Cancer Cells. AB - Cyclooxygenase-2 (COX-2) is an enzyme overexpressed in most types of cancers and has been used for an excellent targetable biomarker. Celecoxib is an effective inhibitor of COX-2, used in anti-inflammation. Herein we report a one and two photon fluorescence probe (NP-C6-CXB) for COX-2, based on the conjugation of naphthalamide with Celecoxib, by using flexible hexylene linker. NP-C6-CXB is nonfluorescent in buffer solution and normal cells, while it shows bright fluorescence in solutions and cancer cells in the presence of COX-2 with an excellent selectivity. Interestingly, NP-C6-CXB can discriminate cancer cells (MCF-7) from normal cells (COS-7) in the single culture medium under confocal microscopy. Due to the selective binding affinity of NP-C6-CXB with a COX-2 enzyme, the intensity is proportional to the level of COX-2 enzyme in cancer cells. In vivo and in vitro experiments proved that NP-C6-CXB is a potential tool for identification of tumor and might be used in surgical resection of COX-2 expressed tumors. PMID- 29587479 TI - Novel 64Cu Labeled RGD2-BBN Heterotrimers for PET Imaging of Prostate Cancer. AB - Bombesin receptor 2 (BB2) and integrin alphavbeta3 receptor are privileged targets for molecular imaging of cancer because of their overexpression in a number of tumor tissues. The most recent developments in heterodimer-based radiopharmaceuticals concern BB2- and integrin alphavbeta3-targeting compounds, consisting of bombesin (BBN) and cyclic arginine-glycine-aspartic acid peptides (RGD), connected through short length linkers. Molecular imaging probes based on RGD-BBN heterodimer design exhibit improved tumor targeting efficacy compared to the single-receptor targeting peptide monomers. However, their application in clinical study is restricted because of inefficient synthesis or unfavorable in vivo properties, which could depend on the short linker nature. Thus, the aim of the present study was to develop a RGD2-BBN heterotrimer, composed of (7-14)BBN NH2 peptide (BBN) linked to the E[ c(RGDyK)]2 dimer peptide (RGD2), bearing the new linker type [Pro-Gly]12. The heterodimer E[c(RGDyK)]2-PEG3-Glu-(Pro-Gly)12 BBN(7-14)-NH2 (RGD2-PG12-BBN) was prepared through conventional solid phase synthesis, then conjugated with 1,4,7,10-tetraazacyclododecane-1,4,7,10 tetraacetic acid (DOTA) or 1,4,7-triazacyclononane-1-glutaric acid-4,7-diacetic acid (NODA-GA). In 64Cu labeling, the NODA-GA chelator showed superior radiochemical characteristics compared to DOTA (70% vs 40% yield, respectively). Both conjugates displayed dual targeting ability, showing good alphavbeta3 affinities and high BB2 receptor affinities which, in the case of the NODA-GA conjugate, were in the same range as the best RGD-BBN heterodimer ligands reported to date ( Ki = 24 nM). 64Cu-DOTA and 64Cu-NODA-GA probes were also found to be stable after 1 h incubation in mouse serum (>90%). In a microPET study in prostate cancer PC-3 xenograft mice, both probes showed low tumor uptake, probably due to poor pharmacokinetic properties in vivo. Overall, our study demonstrates that novel RGD-BBN heterodimer with long linker can be prepared and they preserve high binding affinities to BB2 and integrin alphavbeta3 receptor binding ability. The present study represents a step forward in the design of effective heterodimer or heterotrimer probes for dual targeting. PMID- 29587480 TI - Design and Synthesis of Novel Positive Allosteric Modulators of alpha7 Nicotinic Acetylcholine Receptors with the Ability To Rescue Auditory Gating Deficit in Mice. AB - A series of novel thiazolo[4,5- d]pyrimidin-7(6 H)-ones (3aa-3eq) were designed, synthesized, and evaluated as the type I positive allosteric modulators of human alpha7 nAChR expressed in Xenopus ooctyes by a two-electrode voltage clamp. The structure-activity relationship analysis identified the compound 3ea as a potent and efficacious PAM with the maximum activation effect of the alpha7 current of over 1633% in the presence of acetylcholine (100 MUM) and an EC50 = 1.26 MUM. It is highly specific to alpha7 nAChR over other subtypes of nAChR, 5-HT3A, NMDA, and GABAA receptors. Compound 3ea showed an elimination half-life of 10.8 +/- 1.5 h for 3 mg/kg, i.v., and 7.4 +/- 1.1 h for 60 mg/kg, i.g. in rat. It also exhibited sufficient blood-brain barrier penetration with no significant effect on hERG channel. Most importantly, compound 3ea dose-dependently (0.1-1 mg/kg, i.p.) reversed the prepulse inhibition deficit induced by MK-801 in the mouse schizophrenia model.

In the current study, a turn-on Cobalt Bioluminescent Probe 1 (CBP-1) for the detection of cobalt has been successfully developed based on oxidative C O bond cleavage. This probe exhibited high selectivity and sensitivity toward cobalt over other analytes. By using CBP-1, the successful in vivo imaging of cobalt accumulation was carried out in a mouse model. Such an ability to determine cobalt in living animals provides a powerful technology for studying the system distribution, toxic potency, and biological effect of Co2+. PMID- 29587482 TI - Fog Harvesting with Harps. AB - Fog harvesting is a useful technique for obtaining fresh water in arid climates. The wire meshes currently utilized for fog harvesting suffer from dual constraints: coarse meshes cannot efficiently capture microscopic fog droplets, whereas fine meshes suffer from clogging issues. Here, we design and fabricate fog harvesters comprising an array of vertical wires, which we call "fog harps". Under controlled laboratory conditions, the fog-harvesting rates for fog harps with three different wire diameters were compared to conventional meshes of equivalent dimensions. As expected for the mesh structures, the mid-sized wires exhibited the largest fog collection rate, with a drop-off in performance for the fine or coarse meshes. In contrast, the fog-harvesting rate continually increased with decreasing wire diameter for the fog harps due to efficient droplet shedding that prevented clogging. This resulted in a 3-fold enhancement in the fog harvesting rate for the harp design compared to an equivalent mesh. PMID- 29587483 TI - Clustered Single Cellulosic Fiber Dissolution Kinetics and Mechanisms through Optical Microscopy under Limited Dissolving Conditions. AB - Herein, we describe a new method of assessing the kinetics of dissolution of single fibers by dissolution under limited dissolving conditions. The dissolution is followed by optical microscopy under limited dissolving conditions. Videos of the dissolution were processed in ImageJ to yield kinetics for dissolution, based on the disappearance of pixels associated with intact fibers. Data processing was performed using the Python language, utilizing available scientific libraries. The methods of processing the data include clustering of the single fiber data, identifying clusters associated with different fiber types, producing average dissolution traces and also extraction of practical parameters, such as, time taken to dissolve 25, 50, 75, 95, and 99.5% of the clustered fibers. In addition to these simple parameters, exponential fitting was also performed yielding rate constants for fiber dissolution. Fits for sample and cluster averages were variable, although demonstrating first-order kinetics for dissolution overall. To illustrate this process, two reference pulps (a bleached softwood kraft pulp and a bleached hardwood pre-hydrolysis kraft pulp) and their cellulase-treated versions were analyzed. As expected, differences in the kinetics and dissolution mechanisms between these samples were observed. Our initial interpretations are presented, based on the combined mechanistic observations and single fiber dissolution kinetics for these different samples. While the dissolution mechanisms observed were similar to those published previously, the more direct link of mechanistic information with the kinetics improve our understanding of cell wall structure and pre-treatments, toward improved processability. PMID- 29587484 TI - Experimental and Theoretical Study on Supramolecular Ionic Liquid (IL)-Asphaltene Complex Interactions and Their Effects on the Flow Properties of Heavy Crude Oils. AB - A combined study for understanding the molecular interactions of asphaltenes with molecular species such as ionic liquids (ILs) comprised experimental measurements and computational numerical simulation calculations, using density-functional theory (DFT) with dispersion corrections, molecular dynamics (MD) calculations, and experimental rheological characterization of the heavy crude oils (HCOs), before and after doping with ILs, respectively. The main results show that ILs influence the asphaltenic dimer association by forming supramolecular complexes that modify the properties of crude oils such as viscosity and interfacial tension. The IL-cation and asphaltene-pi ligand molecular interactions seem to dominate the interactions between ionic liquids and asphaltenes, where ILs' high aromaticity index induces a strong interaction with the aromatic hard core of asphaltenes. PMID- 29587485 TI - Wnt Signaling Activates TP53-Induced Glycolysis and Apoptosis Regulator and Protects Against Cisplatin-Induced Spiral Ganglion Neuron Damage in the Mouse Cochlea. AB - AIMS: Cisplatin can damage spiral ganglion neurons (SGNs) and cause sensorineural hearing loss. Wnt activation protects against neomycin-induced hair cell damage in the mouse cochlea, but the role of Wnt signaling in protecting SGNs from cisplatin treatment has not yet been elucidated. This study was designed to investigate the neuroprotective effects of Wnt signaling against cisplatin induced SGN damage. RESULTS: First, we found that Wnt signaling was activated in SGNs after cisplatin treatment. Next, we discovered that overexpression (OE) of Wnt signaling in SGNs reduced cisplatin-induced SGN loss by inhibiting caspase associated apoptosis, thus preventing the loss of SGN function after cisplatin treatment. In contrast, inhibition of Wnt signaling increased apoptosis, made SGNs more vulnerable to cisplatin treatment, and exacerbated hearing loss. TP53 induced glycolysis and apoptosis regulator (TIGAR), which scavenges intracellular reactive oxygen species (ROS), was upregulated in SGNs in response to cisplatin administration. Wnt/beta-catenin activation increased TIGAR expression and reduced ROS level, while inhibition of Wnt/beta-catenin in SGNs reduced TIGAR expression and increased the ROS level. Moreover, OE of TIGAR reduced ROS and decreased caspase 3 expression, as well as increased the survival of SGNs in Wnt inhibited SGNs. Finally, antioxidant treatment rescued the more severe SGN loss induced by beta-catenin deficiency after cisplatin treatment. Innovation and Conclusion: This study is the first to indicate that Wnt signaling activates TIGAR and protects SGNs against cisplatin-induced damage through the inhibition of oxidative stress and apoptosis in SGNs, and this might offer novel therapeutic targets for the prevention of SGN injury.

AB - OBJECTIVES: To evaluate the feasibility, in terms of acute toxicity and symptom control, of CyberKnife (Accuray, Sunnyvale, CA)-based stereotactic radiotherapy (CyberKnife-SRT) for metastatic orbital lesions. METHODS: This retrospective study included patients with symptomatic metastases wholly located within the orbit. Palliative radiation treatment was performed using CyberKnife image-guided technology. Gross tumor volume was defined on a pre-radiotherapy magnetic resonance imaging. Acute and late toxicity was recorded according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Scale. RESULTS: Between April 2012 and July 2016, 21 patients underwent CyberKnife-SRT for 24 orbital metastases from different primary tumors. Median treatment dose was 18 Gy (15-24 Gy) given in a median of 3 fractions (2-3 fractions) with a median dose of 6 Gy/fraction (5-10 Gy/fraction). Acute grade 1 toxicity was observed in eight cases. No local recurrence occurred after median follow-up of 6.2 months (1.1-30.0 months) among 16 lesions that underwent post stereotactic radiotherapy magnetic resonance imaging. All patients reported decreasing pre-stereotactic radiotherapy symptoms without late toxicity. Follow up >6 months (median 22.8 months) was available for nine lesions; complete and partial radiological response was registered in four and five of them, respectively. CONCLUSION: In our experience, CyberKnife-SRT is a well-tolerated treatment that offers high local and symptom control in patients with intraocular and periocular malignant lesions. PMID- 29587487 TI - Retinal vascular speed <0.5 disc diameter per week as an early sign of retinopathy of prematurity requiring treatment. AB - PURPOSE: To analyse the speed of temporal retinal vascularisation in preterm infants included in the screening programme for retinopathy of prematurity. MATERIAL AND METHODS: A total of 185 premature infants were studied retrospectively between 2000 and 2017 in San Cecilio University Hospital of Granada, Spain. The method of binocular indirect ophthalmoscopy with indentation was used for the examination. The horizontal disc diameter was used as a unit of length. Speed of temporal retinal vascularisation (disc diameter/week) was calculated as the ratio between the extent of temporal retinal vascularisation (disc diameter) and the time in weeks. RESULTS: The weekly temporal retinal vascularisation (0-1.25 disc diameter/week, confidence interval) was significantly higher in no retinopathy of prematurity (0.73 +/- 0.22 disc diameter/week) than in stage 1 retinopathy of prematurity (0.58 +/- 0.22 disc diameter/week). It was also higher in stage 1 than in stages 2 (0.46 +/- 0.14 disc diameter/week) and 3 of retinopathy of prematurity (0.36 +/- 0.18 disc diameter/week). The rate of temporal retinal vascularisation (disc diameter/week) decreases when retinopathy of prematurity stage increases. The area under the receiver operating characteristic curve was 0.85 (95% confidence interval: 0.79 0.91) for retinopathy of prematurity requiring treatment versus not requiring treatment. The best discriminative cut-off point was a speed of retinal vascularisation <0.5 disc diameter/week, with a sensitivity and a specificity of 84.8% and 77%, respectively. CONCLUSION: The rate of temporal retinal vascularisation is a quantifiable observation that can help to alert a clinician that treatment of retinopathy of prematurity may be required. However, before becoming a new standard of care for treatment, it requires careful documentation, with agreement between several ophthalmologists. PMID- 29587488 TI - Clinical outcomes of Ahmed glaucoma valve implantation in pediatric glaucoma. AB - PURPOSE: To evaluate the outcomes of Ahmed glaucoma valve implantation in refractory primary congenital glaucoma as well as primary procedure in aphakic glaucoma. METHOD: In this retrospective study, medical records of patients who underwent Ahmed glaucoma valve implantation for refractory glaucoma and aphakic glaucoma were reviewed. Primary outcome measures were the surgical success defined as intraocular pressure <=21 mm Hg and decreased >=20% and no secondary glaucoma surgery. Secondary outcome measures were the number of glaucoma medications, complications, best corrected visual acuity, and intraocular pressure. RESULTS: A total of 62 eyes of refractory primary congenital glaucoma patients (group 1) and 33 eyes of aphakic glaucoma patients (group 2) were included in our study. Mean follow-up was 51 +/- 33 months in group 1 and 49 +/- 41 months in group 2 (p = 0.82). The cumulative probability of success was 90% in both groups at the first year; however, the success rate was 52.5% in group 1 and 71.5% in group 2 at 5 years' follow-up visit. In group 1, the mean intraocular pressure +/- standard deviation was 33.1 +/- 8.6 mm Hg at the baseline and decreased to 17.1 +/- 5.3 mm Hg at 1 year and 18.5 +/- 6.4 at 3 years postoperatively (all p's < 0.001). Corresponding values for group 2 were 28.9 +/- 6.1, 15.2 +/- 4.6, and 16.0 +/- 5.9 mm Hg, respectively (all p's < 0.001). The baseline number of glaucoma medications was 3 +/- 0.7 that decreased to 2 +/- 0.8 at final follow-up (p = 0.02). CONCLUSION: Ahmed glaucoma valve implantation has a moderate success rate in the management of refractory primary congenital glaucoma with an increased chance of tube-related complications. The surgical success rate is higher in case of primary Ahmed glaucoma valve implant for aphakic glaucoma with acceptable safety profile. PMID- 29587489 TI - EB 2017 Article: Changes in advanced glycation end products, beta-defensin-3, and interleukin-17 during diabetic periodontitis development in rhesus monkeys. AB - The bidirectional relationship between diabetes mellitus (DM) and periodontal disease has drawn great attention; however, the mechanisms underlying their association remain unclear. In this study, we aimed to develop a rhesus monkey model of diabetic periodontitis and explore the potential mechanisms by which DM affects the progression of periodontal disease. Three healthy rhesus monkeys were selected as the control group. Five streptozotocin-induced diabetic rhesus monkeys were chosen as the experimental group. Ligature placement was used to induce periodontitis. The changes in the levels of advanced glycation end products (AGEs), beta-defensin-3 (BD-3), and interleukin-17 (IL-17) were measured using enzyme-linked immunosorbent assays (ELISA) and real-time reverse transcription polymerase chain reaction (RT-PCR) at different stages during disease progression. Periodontitis was confirmed by clinical assessment, radiographic images, and histological examination. Significant changes in the levels of AGEs and BD-3 in serum were observed at the periodontitis stage in diabetic rhesus monkeys ( P < 0.05). The expression of BD-3 mRNA in the gingiva of diabetic group at baseline was significantly high ( P < 0.05). Diabetic monkeys exhibited significantly enhanced IL-17 mRNA expression at the periodontitis stage ( P < 0.05). Our findings indicated that the rhesus monkey can serve as an ideal model for exploring the pathogenesis of diabetic periodontitis, and the hyperglycemic environment may accelerate inflammatory response and weaken the defense system in periodontal tissues. Impact statement The mechanism underlying the association between diabetes mellitus (DM) and periodontal disease is not yet fully understood. Hence, there is a need to establish animal models to reveal the effect of DM on the pathogenesis of periodontitis. In this study, we explored the appropriate methods for inducing periodontitis and shortening the modeling time in rhesus monkeys, to investigate the pathogenesis of diabetic periodontitis and develop innovative therapies. Our results suggest that a hyperglycemic environment might lead to the destruction of periodontal tissues by accelerating inflammatory response and weakening the defense system in periodontal tissues. Therefore, this study has significant treatment implications regarding the regulation of the immune response against periodontal diseases in patients with DM. PMID- 29587490 TI - The impact of social support and partner relationship dynamics on engagement in HIV care and antiretroviral treatment adherence among MSM in Latin America. AB - In Latin America (LA), HIV prevalence among MSM is estimated at thirty times greater than in the general male population. Little is known about the role of social support or disclosure status in relation to the HIV care continuum among LA MSM. Using multivariable logistic generalized estimation equations, we assessed the impact of social support satisfaction and disclosure status on engagement in HIV care, ART initiation, and ART adherence with data from an online, multinational sample of HIV infected MSM in Latin America (N = 2,350). 80.0% were engaged in HIV care, 71% initiated ART, and among those, 37% reported missing at least one dose in the past month. In multivariable models, compared to being very satisfied with social support, being somewhat satisfied (aOR = 0.73, 95% CI 0.56, 0.95) or somewhat dissatisfied (aOR = 0.83, 95% CI 0.70, 0.98) were associated with reduced odds of reporting 100% ART adherence. Disclosure of status was associated with a greater odds of HIV care engagement (OR = 1.63, 95% CI 1.28, 2.07) and ART initiation (OR = 1.55, 95% CI 1.30, 1.84). Greater satisfaction with social support and comfort disclosing HIV status to these sources were associated with improved engagement in HIV care and greater initiation of ART among MSM in LA. PMID- 29587491 TI - Graft-free glaucoma drainage device implantation: Short tunnel small flap technique. AB - PURPOSE: To introduce a new technique of short tunnel small flap graft-free glaucoma drainage device implantation and report our early experience. METHODS: In a retrospective study, patients with uncontrolled primary open-angle glaucoma underwent short tunnel small flap graft-free Ahmed glaucoma valve implantation. In this technique, plate is sutured 8-10 mm posterior to the limbus and a partial thickness flap is made at 1 or 11 o'clock position, 1 mm posterior the limbus. Tube was passed through a tunnel immediately anterior to the plate into the proximal edge of the flap and then inserted into the anterior chamber via a route underneath the flap. Flap then covered the distal end of the tube and conjunctiva was sutured. Patients were followed for a minimum of 12 months for any sign of tube exposure and rise of intraocular pressure. RESULTS: A total of 16 consecutive patients with refractory primary open-angle glaucoma and uncontrolled intraocular pressure were included in this study. Mean age of participants was 59 +/- 8.3 years and nine (56%) were male. Mean intraocular pressure at the time of presentation was 26 +/- 6.2 mm Hg, which dropped to 16 +/- 4.5 at 12 months postoperative follow-up. The number of medications at baseline was 3 +/- 1 eye drops, which was decreased to 1 +/- 1.2 at 12 months. There were no conjunctival and flap-related complications or any sign of tube exposure during 1-year postoperative period. CONCLUSION: Short tunnel small flap graft-free glaucoma drainage device implantation technique combines advantages of both tunneling and flap techniques. Also, it may result in better tube positioning and more favorable cosmetic outcomes. PMID- 29587492 TI - HIV-1 Genetic Diversity in Recently Diagnosed Infections in Moscow: Predominance of AFSU, Frequent Branching in Clusters, and Circulation of the Iberian Subtype G Variant. AB - HIV-1 protease-reverse transcriptase sequences from 62 HIV-1-infected individuals recently diagnosed in Moscow were analyzed. Subtype A former Soviet Union (FSU) (AFSU) variant was the predominant clade (62.9%), followed by subtype B (22.6%), unique recombinants (6.5%), subtype G (6.5%), and CRF01_AE (1.6%). AFSU predominated among people who inject drugs (88.9%) and heterosexually acquired infections (77.8%), while subtype B was the most prevalent genetic form among men who have sex with men (44%), although AFSU was also frequent in this population (36%). Forty-eight (77.4%) viruses branched within intrasubtype clusters, three of which, of subtype B, had a majority of viruses collected outside of FSU. The four subtype G viruses identified in this study belonged to the Portuguese Spanish (Iberian) variant and, together with three from databases, formed a Russian cluster closely related to viruses from Denmark. This is the first report of the circulation of the Iberian subtype G variant in Russia. PMID- 29587493 TI - Molecular characterization of fowl aviadenoviruses species D and E associated with inclusion body hepatitis in chickens and falcons indicates possible cross species transmission. AB - During the period from 2015 to 2017, frequent outbreaks of inclusion body hepatitis (IBH) were observed in broiler chickens and falcons in Saudi Arabia. Fifty samples were collected from both species. The histopathological examination and polymerase chain reaction confirmed the IBH infection in eight samples (five samples from chickens and three samples from falcons). The genomic sequence and phylogenetic analysis based on nucleotide and amino acid sequences of Saudi strains, reference fowl aviadenoviruses (FAdVs) and field viruses available in Genbank revealed that all investigated FAdVs clustered into FAdV-2 (species D) and FAdV-6 (species E). The host-dependent characterization revealed that falcon origin strains showed low identity (~35%) with falcon adenoviruses isolated from USA, which clustered into a separate group. The identification of FAdV-D and FAdV E in diseased falcons and chickens indicates cross-species transmission although falcons and chickens are phylogenetically different. The control of IBH infection in falcons and chickens should be based on the separation of carriers and susceptible chickens as well as falcons to prevent cross-species contact. Vaccination is an important method for prevention of IBH. The characterization of newly emerging FAdV strains provides valuable information for the development of an efficacious control strategy based on the molecular structure of current circulating FAdV strains in different species of birds. PMID- 29587494 TI - Species Dynamics in Phytoplankton Blooms: Incomplete Mixing and Competition for Light. AB - With the eutrophication of many freshwaters and coastal environments, phytoplankton blooms have become a common phenomenon. This article uses a reaction-diffusion model to investigate the implications of mixing processes for the dynamics and species composition of phytoplankton blooms. The model identifies four key parameters for bloom development: incident light intensity, background turbidity, water column depth, and turbulent mixing rates. The model predicts that the turbulent mixing rate is a major determinant of the species composition of phytoplankton blooms. In well-mixed environments, the species with lowest "critical light intensity" should become dominant. But at low mixing rates, the species with lowest critical light intensity is displaced if other species obtain a better position in the light gradient. Instead of a gradual change in species composition, the model predicts steep transitions between the dominance regions of the various species. The model predicts a low species diversity: phytoplankton blooms in eutrophic environments should be dominated by one or a few species only. The model predictions are consistent with laboratory competition experiments and many existing field data. We recommend examining competition in phytoplankton blooms under well-controlled laboratory conditions, and we derive scaling rules that facilitate translation from the laboratory to the field. PMID- 29587495 TI - Dispersal-Dependent Oviposition and the Aggregation of Parasitism. AB - The prediction that parasitoid foraging effort should increase with distance traversed to reach or to locate hosts has had little experimental attention. Consistent with a number of models of foraging behavior, we found that the per capita number of ovipositions by the minute fairyfly-egg parasitoid Anagrus sophiae increased significantly with dispersal distance to planthopper hosts in the field in experimental patches of many host eggs. In large continuous stands of cordgrass host plants, after dispersal of decimeters or less, female wasps laid approximately 18% of their average of 18.6 eggs. After dispersal to plants isolated 10 m from other cordgrass, they laid approximately 84%, and they laid virtually all of their eggs after dispersal of 250 m to experimental floating islands of cordgrass. The increased oviposition following dispersal tripled the CV2 index of aggregation of parasitism to a level theoretically sufficient to promote locally stable parasitoid-host dynamics in isolated patches. At the same time, the change in wasp behavior did not affect the relationship between parasitism and host density, which was consistently density independent. Our results suggest that increased foraging effort with distance traversed can counter Allee effects in colonization and increase spatial spread of populations of natural enemies. PMID- 29587496 TI - Adult Survival and Imperfect Assessment of Parentage: Effects on Male Parenting Decisions. AB - Applications of molecular methods to assess parentage have revealed that the distribution of reproductive success among individuals often differs, sometimes dramatically, from expectation based on observation of behavioral association. Much theory exists on whether and when males should reduce parental care in response to level of paternity. Life-history theory predicts that trade-offs in reproductive effort should be influenced by adult survival. We used a dynamic programming approach to address how level of paternity, ability to assess paternity, and adult survival rate interact to affect male tolerance of reduced parentage in a given brood. Adult survival has the greatest influence on male decisions such that, for any given cost of reproduction and value of male care, tolerance of extrapair fertilizations (EPFs) decreases as adult survival increases. An unexpected result of these models is that an optimal response also depends on a male's ability to predict probability of parentage (i.e., uncertainty). These models better characterize the nature of paternity uncertainty and its effect on EPF tolerance than have previous models and add to our understanding of the complex relationship between uncertainty, mating strategies, and adult survival. PMID- 29587497 TI - A Dynamical Theory of Speciation on Holey Adaptive Landscapes. AB - A holey adaptive landscape is an adaptive landscape where relatively infrequent well-fit combinations of genes form a contiguous set that expands throughout the genotype space. I formulate and study a series of simple models describing the dynamics of speciation on holey adaptive landscapes driven by mutation and random genetic drift. Unlike most previous models that concentrate only on some stages of speciation, the models studied here describe the complete process of speciation from initiation until completion. The evolutionary factors included are selection (reproductive isolation), random genetic drift, mutation, recombination, and migration. In these models, pre- and postmating reproductive isolation is a consequence of cumulative genetic change. I study possibilities for speciation according to allopatric, parapatric, peripatric, and vicariance scenarios. The results presented here, together with earlier numerical simulations, strongly suggest that rapid speciation, including simultaneous emergence of several new species, is a plausible outcome of the evolutionary dynamics of subdivided populations. Rapid speciation is most likely for populations that are subdivided into a large number of small subpopulations. Speciation is possible even when subpopulations exchange several individuals per generation. Selection for local adaptation is not necessary for rapid speciation. I briefly discuss implications of the dynamics on holey adaptive landscapes for the nearly neutral theory of molecular evolution and for the theory of evolution of genetic canalization. PMID- 29587498 TI - Matings Systems and the Evolution of Niche Breadth. AB - Several theoretical studies of niche breadth evolution have shown that niche breadth expansion can only occur under a limited set of conditions. These studies have assumed that mating pairs form at random within spatial subpopulations. I show here that nonrandom mating within spatial subpopulations can greatly alter niche breadth evolution. Niche breadth expansion is restricted by assortative mating but is permitted by sexual selection. When new populations are formed by a single pulse of immigrants, the ability to persist in novel but similar environments is enhanced by sexual selection. When new populations receive a constant stream of immigrants, sexual selection allows the evolution of increased niche breadth even when the novel environment is very different from the ancestral environment. These results suggest that species lineages that exhibit sexual selection will have broader niches than species lineages that mate randomly or assortatively. PMID- 29587499 TI - Multiple Sexual Ornaments Coevolve with Multiple Mating Preferences. AB - In species where males have several ornaments for mate attraction, each ornament may coevolve with a different female preference. Alternatively, multiple ornaments may be sexually selected for because they stimulate the same, single, female preference. In the latter case, measures of preferences for different ornaments are essentially measures of the same phenotypic character and, thus, will be strongly pleiotropic, whereas no such expectation exists for multiple preferences. We selected directly up and down on two visual ornaments, orange and black coloration, in male guppies (Poecilia reticulata) in order to impose indirect selection on the female preference or preferences for these ornaments. Preferences for the two colors responded in a pattern similar to the response of the ornaments themselves. That female preferences for orange and for black in this guppy population are able to respond to selection more or less independently, suggests that they are probably two different characters in an evolutionary sense. Each of these preferences appears to be genetically correlated with the respective ornament. PMID- 29587500 TI - Nonequilibrium Population Dynamics of "Ideal and Free" Prey and Predators. AB - Aggregated spatial distributions of prey and predators promote stability of the otherwise unstable Nicholson-Bailey model. Nevertheless, when both predators and prey choose patches in an ideal free way, sufficiently aggregated distributions will only arise if patch quality (e.g., reflected in prey fecundity) is very heterogeneous. This requirement profoundly limits the possibilities for simultaneous population dynamical and evolutionary stability. However, stability is not necessary for coexistence. Under cyclic or chaotic dynamics, the rate at which species change their distributions becomes important. Here we consider two endpoints of a continuum of rates. The first is "rigid" selection of patch types based on the expected long-term distribution of conditions. The second is "flexible" selection based on current conditions. We carried out systematic surveys of the population-level consequences of coevolutionarily stable patch selection strategies for different combinations of rigid and flexible strategies of predator and prey. First, if both prey and predators have rigid strategies, the evolutionary end result is either a stable population dynamical equilibrium or diverging cycles eventually leading to extinction. Second, for the case with rigid prey and flexible predators, the persistence boundary in parameter space is shifted from the boundaries obtained for rigid predators. The mechanism underlying persistence is different in that the flexible strategies of the predators destabilize the equilibrium, while the evolutionary response of the rigid prey leads to reduced cycles. Third, if both prey and predators are flexible, simulations lead either to chaotic fluctuations or to extinction (but not to stable equilibria, nor to limit cycles), and the conditions for coexistence are much wider than those under rigid patch selection. These simulations suggest that information constraints on adaptive patch choice have a major impact on predator-prey persistence under nonequilibrium conditions. We discuss how these predictions can be tested by field observations on expansions and contractions in dietary range (or habitat range) in relation to population fluctuations.

PMID- 29587503 TI - The Diverse Effects of Intraspecific Competition on the Selective Advantage to Resistance: A Model and Its Predictions. AB - We constructed a model to investigate conditions under which intraspecific competition amplifies or diminishes the selective advantage to resistance. The growth trajectories of competing individual plants were depicted by logistic difference equations that incorporated basic costs (lowered growth rate) and benefits (lowered damage) of defense. Analytical results showed that when competition is absent, resistance is favored by high damage, low cost, and slow growth rate. Competition makes selection more complex. When herbivore damage reduces the size of a susceptible plant, resistant neighbors can usurp its resources and thus suppress its regrowth. This competitive interaction amplifies the relative fitness of the resistants. Numerical simulations explored a broader range of conditions. Three factors were varied: competition mode (symmetric vs. asymmetric), resistance type (damage avoidance vs. damage reduction), and timing of attack (early, mid, or late season). We found that competition mode had drastic effects on outcomes. Under symmetric competition, increased plant density intensified the selective advantage of resistance, damage avoidance was more strongly favored than damage reduction, and resistance to late attack was more favored than to early attack. Asymmetric competition had opposite effects: selection acted against resistance at high density, damage reduction was more strongly favored, and resistance against early attack was more favored. Interestingly, the two competition modes induced opposite patterns of density dependent selection. The difference between the symmetric and asymmetric cases is explained by the fact that resistance costs during the preattack phase are more strongly amplified by asymmetric competition. When resistance is induced, so that preattack costs of resistance are zero, asymmetric competition more strongly amplified the benefits during the postattack phase. The prediction that selection on resistance will be plant density-dependent has complex implications for the evolutionary dynamics of defense evolution. PMID- 29587504 TI - Population Numbers Count: Tools for Near-Term Demographic Analysis. AB - How do unit or proportional changes in vital rates affect populations in the short term? We present a new extension to standard methods of matrix model analysis that allows us to answer this question for the first time. By using the sensitivities of all the eigenvalues/vectors, rather than just the leading eigenvalue/vector pair, we can predict the consequences of unit or proportional changes in vital rates to population size and structure at any arbitrary time, not just when populations have neared their stable distribution. These extensions are particularly important in studying populations subject to frequent disturbance, where stable growth rate and stable distribution do not provide sufficient information about the effects of changes in the vital rates; managed populations in which short-term goals are defined; and the adequacy of the underlying matrix model for either short- or long-term understanding. We use analysis of empirical data on the cactus Coryphantha robbinsorum to demonstrate this approach and show that short-term predictions can differ substantially from those based on standard, asymptotic, analysis. PMID- 29587505 TI - Allocation to Mate Guarding or Increased Sperm Production in a Mediterranean Wrasse. AB - An excellent body of literature exists that examines sperm expenditure when males allocate only to sperm production. However, in many species, males can also allocate energy to behaviors that influence sperm competition. We model whether males in sperm competition should allocate energy to mate guarding or additional sperm production. Mate guarding is predicted to lead to greater reproductive success than increased sperm output, and mate-guarding males are not predicted to alter their allocation to sperm production with increasing sperm competition. Only when mate guarding is ineffective or greatly reduces sperm production are males predicted to allocate to sperm production. In a Mediterranean wrasse Symphodus ocellatus, three male alternative reproductive behaviors coexist. While nesting males and satellites guard mates to decrease sperm competition, sneaker males only compete via sperm production. Sneakers produce four times as much sperm per spawn as either nesting males or satellites. As predicted by the model, mate guarding but not sperm production increased with increased risk of sperm competition in nesting males. We argue that this can be explained by nesting males allocating to mate guarding rather than sperm production. Considering allocation among behaviors that affect sperm competition enhances our ability to explain and to predict sperm allocation patterns. PMID- 29587506 TI - Geometrical Games between a Host and a Parasitoid. AB - Avoiding detection by parasitoids is nearly impossible for most leafminers in their visually striking mines, and they often suffer from a high mortality rate by a great variety of parasitoid species. The leafminer-parasitoid interaction bears a strong resemblance to the princess-monster game developed in game theory, in which a "monster" (parasitoid) selects an optimal search strategy to capture the "princess" (leafminer), while the princess selects an optimal strategy to hide from the monster. This article attempts to illustrate and to quantify the additional complexity that occurs when the princess can modify the arena in which the monster searches. Feeding activity of the leafminer Phyllonorycter malella creates feeding windows, which are spots on the mine. Its main parasitoid Sympiesis sericeicornis is able to insert its ovipositor only through these feeding windows. Parasitism risk depends both on the leafminer-feeding pattern, which determines the structure of the arena in which the parasitoid searches, and on the position of the leafminer within the mine. The adaptive value of observed patterns of mine development and leafminer behavior is evaluated by comparing them to predictions from a simulation model of random patterns and leafminer positions. The leafminer creates a heterogeneous environment by leaving a central area of uneaten tissue. This area acts as a protecting shield and greatly diminishes the risk of parasitism. Hence, by controlling the structure of the arena in which the princess-monster game is played, the leafminer defines some of the rules of the game. PMID- 29587507 TI - Lower Species Richness in Dioecious Clades. AB - Despite the extensive research on the potential benefits of dioecy to individuals, little is known about the long-term success of dioecious lineages in relation to their hermaphroditic or monoecious relatives. This study reports on the evolutionary success of worldwide dioecious flora in light of recent phylogenetic work by performing sister-group comparisons of species richness between clades of angiosperms with different breeding systems. Whether this analysis is performed at the family or genus level, species richness is generally far lower in dioecious taxa when compared to their hermaphroditic or monoecious sister taxa. Despite the advantages of avoiding inbreeding depression and of allocating resources separately to male and female function, dioecy in angiosperms does not appear to be a key innovation promoting evolutionary radiation. A potential explanation for the low representation of dioecious lineages is that dioecious plants may have lower colonization rates. Baker's Law states that self-compatible lineages will have higher rates of successful long range dispersal since they do not require a mate; consequently, self-compatible lineages may have higher rates of allopatric speciation. However, identical analyses performed with hermaphroditic self-incompatible angiosperms did not produce similar results, suggesting that Baker's law is not the reason for the poor representation of dioecy among angiosperm species. PMID- 29587508 TI - Extinction Thresholds and Metapopulation Persistence in Dynamic Landscapes. AB - Models of metapopulations have focused on the effects of extinction and colonization rate upon metapopulation persistence and dynamics, assuming static landscapes wherein patches are neither created nor go extinct. However, for species living in ephemeral (patchy) habitats, landscapes are highly dynamic rather than static. In this article, we develop a lattice metapopulation model, of the patch occupancy type, based on interacting particle systems that incorporate explicitly both metapopulation and patch dynamics. Under this scenario, we study the effects of different regimes of patch dynamics upon metapopulation persistence. We analyze the lattice behavior by numerical simulations and a mean field approximation (MF). We show that metapopulation persistence and extinction are strongly influenced by the rate at which the landscape changes, in addition to the amount of habitat destroyed. We derive MF analytical expressions for extinction thresholds related to landscape properties such as habitat suitability and patch average lifetime. Using numerical simulations, we also show how these thresholds are quantitatively overestimated by the MF equations, although the qualitative behavior of the spatial model is well explained by the MF when the array of habitat patches is dynamic or static but connected in space and time. The implications for conservation are also discussed. PMID- 29587509 TI - Scaling Down: On the Challenge of Estimating Abundance from Occurrence Patterns. PMID- 29587510 TI - Reproductive Isolation Mechanism Resulting from Resolution of Intragenomic Conflict. AB - Crosses have revealed the species-specific, positively correlated intensities of paternally expressed growth enhancer (GE) and maternally expressed growth suppressor (GS), which serve as a reproductive isolation mechanism in many plants and animals. However, how this mechanism evolved has remained unanswered. A dynamic model shows that the conflict between paternally and maternally inherited genomes may drive them to an evolutionary "arms race" of their GE and GS productions, respectively. This results in paternally expressed GE and maternally expressed GS, and their evolutionarily stable intensities are both decreasing functions of species-specific degree of paternity and GE and GS production costs, thereby establishing a mechanism for postzygotic isolation. PMID- 29587511 TI - Estimating Species Abundance from Occurrence. PMID- 29587512 TI - The Effect of Parasites on Host Population Density and Extinction: Experimental Epidemiology with Daphnia and Six Microparasites. AB - Parasites have been shown to reduce host density and to induce host population extinction in some cases but not in others. Epidemiological models suggest that variable effects of parasites on individual hosts can explain this variability on the population level. Here, we aim to support this hypothesis with a specific epidemiological model using a cross-parasite species approach. We compared the effect of six parasites on host fecundity and survival to their effects on density and risk of extinction of clonal host populations. We contrast our empirical results of population density with predictions from a deterministic model and contrast our empirical results of host and parasite extinction rates with those predicted by a stochastic model. Five horizontally transmitted microparasites (two bacteria: white bacterial disease, Pasteuria ramosa; two microsporidia: Glugoides intestinalis, Ordospora colligata; one fungus: Metschnikowiella biscuspidata); and six strains of a vertically transmitted microsporidium (Flabelliforma magnivora) of the planktonic crustacean Daphnia magna were used. In life table experiments, we quantified fecundity and survival in individual parasitized and healthy hosts and compared these with the effect of the parasites on host population density and on the likelihood of host population extinction in microcosm populations. Parasite species varied strongly in their effects on host fecundity, host survival, host density reduction, and the frequency with which they drove host populations to extinction. The fewer offspring an infected host produced, the lower the density of an infected host population. This effect on host density was relatively stronger for the vertically transmitted parasite strains than for the horizontally transmitted parasites. As predicted by the stochastic simulations, strong effects of a parasite on individual host survival and fecundity increased the risk of host population extinction. The same was true for parasite extinctions. Our results have implications for the use of microparasites in biological control programs and for the role parasites play in driving small populations to extinction. PMID- 29587513 TI - Allometric Slopes and Independent Contrasts: A Comparative Test of Kleiber's Law in Primate Ranging Patterns. AB - At the most fundamental level, the size of an animal's home range is determined by its energy needs. In the absence of confounding variables, home range size should therefore scale with body mass according to Kleiber's exponent for metabolic rate of 0.75. Comparative studies in a wide range of taxa have failed to confirm this prediction: home range size has commonly been found to scale with an exponent significantly >0.75. We develop a comparative measure of metabolic needs that incorporates both mass-specific metabolic rate and social-group size. We test the prediction that home range size in primates scales isometrically with this measure when an appropriate linear model is applied to data corrected for phylogenetic bias. Analyses using species values as data points indicate an exponent consistent with Kleiber's law. This result is misleading, however, because ecological factors confound the analysis, and the slopes within some ecologically homogeneous taxa are steeper. Accordingly, in analyses based on independent contrasts with reduced major axis, slopes are significantly greater than predicted by Kleiber's law. We examine the effects of other variables, and we find that systematic variation in substrate use, home range overlap, and diet account for the steeper than expected relationship between home range size and metabolic needs based on Kleiber's law. We therefore conclude that the scaling of home range size is subject to Kleiber's law but in combination with other factors. These results emphasize that the study of allometry requires detailed attention to statistical models and control of confounding variables. PMID- 29587514 TI - Rensch's Rule Crosses the Line: Convergent Allometry of Sexual Size Dimorphism in Hummingbirds and Flower Mites. AB - Hummingbirds demonstrate the full scope of Rensch's rule (females larger than males in small species, males larger than females in large species). The phoretic flower mites that hummingbirds compete with for nectar show the same pattern. An analysis of phylogenetically independent contrasts for 154 hummingbird and 37 mite species confirmed that both small (female-larger) and large (male-larger) species contribute to this result. I propose a common cause for this convergent pattern of sexual size dimorphism, with support from ecological and behavioral data for both groups. When morphology or behavior constrains each species to a limited range of resource densities, natural selection tends to diversify body size among species. If mating is promiscuous or polygynous, sexual selection favors larger males when resources are sufficient. But if male reproductive behavior is energetically costly, smaller males may have an advantage when resources are limiting, producing a pattern of allometry for sexual size dimorphism that conforms with Rensch's rule. Stabilizing selection on female size, if it occurs, amplifies this pattern. When the resource-density spectrum is broad enough, both female-larger and male-larger size dimorphism should occur within the same clade. PMID- 29587515 TI - Biodiversity, Stability, and Productivity in Competitive Communities. AB - Three markedly different models of multispecies competition-one mechanistic, one phenomenological, and one statistical-all predict that greater diversity increases the temporal stability of the entire community, decreases the temporal stability of individual populations, and increases community productivity. We define temporal stability as the ratio of mean abundance to its standard deviation. Interestingly, the temporal stability of entire communities is predicted to increase fairly linearly, without clear saturation, as diversity increases. Species composition is predicted to be as important as diversity in affecting community stability and productivity. The greater temporal stability of more diverse communities is caused by higher productivity at higher diversity (the "overyielding" effect), competitive interactions (the "covariance" effect), and statistical averaging (the "portfolio" effect). The relative contribution of each cause of temporal stability changes as diversity increases, but the net effect is that greater diversity stabilizes the community even though it destabilizes individual populations. This theory agrees with recent experiments and provides a degree of resolution to the diversity-stability debate: both sides of the longstanding debate were correct, but one addressed population stability and the other addressed community stability.

AB - BACKGROUND: Acne keloidalis nuchae (AKN) is a chronic scarring folliculitis with limited interventions of both high efficacy and low morbidity. OBJECTIVE: To assess the efficacy of the long-pulsed 1064-nm neodymium-doped yttrium-aluminum garnet (Nd:YAG) laser and topical steroids as a treatment for AKN compared to topical steroids alone. METHODS: We conducted a single-blinded, randomised, within-patient right-left controlled trial (n = 13). Eight monthly laser treatments were performed on the treated half of the scalp, and triamcinolone 0.1% cream was applied to both sides twice daily. Treatment response was measured using a global assessment score (0 to 10). RESULTS: The laser-treated side showed greater improvement in global assessment score. The mean change was -3.2 (-49.2%) on the treated side and -2.2 (-32.8%) on the control side ( P = .144). Papules responded well to laser treatment, while larger plaques and nodules showed limited improvement. In the 10 patients with papules only, the difference in improvement between the treated and control sides was statistically significant (mean change was -3.5 [-59.3%] for the treated side and -1.8 [-29.5%] for the control side, P = .031). LIMITATIONS: This study was limited by a small sample size and a high dropout rate, as well as the lack of a standardised scoring system for AKN. CONCLUSION: The long-pulsed Nd:YAG laser in conjunction with topical steroids shows promising results in the treatment of AKN, particularly the papular component, and is well tolerated by patients.

Nevertheless, its acceptance by terminal stage patients and health-care professionals has not been studied in depth and is not free from controversy. OBJECTIVES: To understand the significance, appropriateness, and pertinence of the use of humor in palliative care and to analyze its applicability. DESIGN: A narrative systematic review was undertaken and included in PROSPERO. DATA SOURCES: Online searches were carried out on PUBMED, PSYCINFO, EBSCO (CINHAL), EMBASE, SCIELO, SCOPUS, TESEO, WEB of SCIENCE, and COCHRANE between their launch date and December 31, 2015, complemented with manual searches with queries to experts. A total of 156 studies were identified, which were then filtered in pairs by means of an established hierarchy, selecting studies that discussed the use of humor specifically in palliative care from all perspectives and designs, and finally published in Spanish, English, French, or Portuguese. Critical reading of all the selected studies took place, with no exclusions due to quality evaluation. RESULTS: Thirty four studies were included. Five main topics were identified: (1) definition of humor, (2) use and functions of humor in palliative care, (3) how to use humor, (4) when not to use humor, and (5) humor before and after the diagnosis of terminal illness. CONCLUSIONS: Humor plays an unquestionable role in palliative care, but its use needs training and appropriate use. PMID- 29587521 TI - Orthotopic heart transplantation in children. AB - Heart transplantation is a relatively infrequent but technically demanding procedure in pediatric cardiac surgery. Orthotopic heart transplantation is often offered to older children or adolescents following multiple previous operations, but with advances in intensive care, diagnostics, and management, more infants with complex congenital heart diseases are being listed for transplantation. Primary cardiomyopathies remain the most common indication. Outcomes following cardiothoracic transplantation have improved steadily in recent times. Donor availability has been helped by increasing public awareness and donation after cardiac death, especially of lungs, increasing the number of patients benefiting from heart and/or lung transplantation. While there are still insufficient donors to meet the current needs, effective devices to bridge patients to transplantation are now widely used. Although the many advances have improved the outlook of transplantation, there are still difficulties that have not changed over time. Nevertheless, heart transplantation in children carries a reasonably good survival rate over the entire spectrum of recipient heart conditions. We discuss the salient features of acceptance of an organ and the technical aspects of both simple and complex heart transplantation in children. PMID- 29587522 TI - Surgical treatment of pulmonary metastasis: report from a tertiary care center. AB - Objective This retrospective analysis aimed to determine the factors influencing prognosis in adult patients who presented to our thoracic surgery service with lung metastases and were eligible for pulmonary metastasectomy. Methods We retrospectively reviewed the data of 296 patients who underwent resection of 575 lung metastases from January 2000 to January 2016. Univariate and multivariate analyses were performed based on age, sex, histology of the primary tumor, disease-free interval, number and size of metastases. Results Sixty-eight (22.97%) patients developed lung metastases from bone sarcoma, 68 (22.97%) from soft-tissue sarcoma, 56 (18.9%) from head and neck cancers, 46 (15.5%) from colorectal cancer, and 58 (19.6%) from other epithelial tumors. The mean size of the lung nodules was 2.48 cm. Open surgical resection was performed in 217 (73.3%) patients. After a mean follow-up of 43 months, 120 (40.7%) patients had died or were lost to follow-up. Univariate analysis confirmed that patients with bone cancer, soft tissue sarcoma, or colorectal carcinoma had a worse prognosis ( p = 0.0003). Moreover, those with a disease-free interval >24 months had a better 5-year survival ( p = 0.0001). The number and size of metastases, age, and sex had no effect on prognosis. The actuarial survival after complete metastasectomy was 71.6% (95% confidence interval: 66-75) at 2 years and 59.3% (95% confidence interval: 56-64) at 5 years. Conclusions Pulmonary metastasectomy provides good long-term survival. The type of primary tumor and disease-free interval are independent prognostic factors for survival. PMID- 29587523 TI - Assessment of electrocardiographic criteria of left atrial enlargement. AB - Background Left atrial enlargement is considered to be a robust, strong, and widely acceptable indicator of cardiovascular outcomes. Echocardiography is the gold standard for measurement of left atrial size, but electrocardiography can be simple, cost-effective, and noninvasive in clinical practice. This study was undertaken to assess the diagnostic accuracy of an established electrocardiographic criterion for left atrial enlargement, taking 2-dimensional echocardiography as the gold-standard technique. Methods A cross-sectional study was conducted on 146 consecutively selected patients with the complaints of dyspnea and palpitation and with a murmur detected on clinical examination, from September 10, 2016 to February 10, 2017. Electrocardiography and echocardiography were performed in all patients. Patients with a negative P wave terminal force in lead V1 > 40 ms.mm on electrocardiography or left atrial dimension > 40 mm on echocardiography were classified as having left atrial enlargement. Sensitivity and specificity were calculated to assess the diagnostic accuracy. Results Taking 2-dimensional echocardiography as the gold-standard technique, electrocardiography correctly diagnosed 68 patients as positive for left atrial enlargement and 12 as negative. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of electrocardiography for left atrial enlargement were 54.4%, 57.1%, 88.3%, 17.4%, and 54.8%, respectively. Conclusion The electrocardiogram appears to be a reasonable indicator of left atrial enlargement. In case of nonavailability of echocardiography, electrocardiography can be used for diagnosis of left atrial enlargement.

AB - PURPOSE: To study ocular manifestations of Marfan syndrome in children and adolescents. METHODS: Retrospective comparative cohort study on consecutive patients up to age 17 years, presenting to the interdisciplinary Marfan clinic of Charite-University Medicine Berlin over a period of 4 years. RESULTS: A total of 52 Marfan syndrome patients and 73 controls were enrolled. In Marfan syndrome eyes, the cornea was flatter (mean keratometry, 40.86 +/- 2.13 vs 42.55 +/- 1.55 diopters in control eyes, p < .001) and corneal astigmatism was greater (1.50 +/- 1.22 vs 0.88 +/- 0.49 diopters in control eyes, p < .001). The central cornea was thinner in Marfan syndrome eyes (537.35 +/- 40.64 vs 552.95 +/- 38.57 MUm, p = 0.007) and Marfan syndrome eyes were more myopic than control eyes (spherical equivalent, -2.77 +/- 4.77 vs -0.64 +/- 1.92 diopters, p < .001). Visual acuity was reduced (logMAR 0.11 +/- 0.17 vs 0.04 +/- 0.26, p = 0.014) and intraocular pressure was lower in Marfan syndrome eyes. Iris transillumination defects were more common in Marfan syndrome eyes (19.6% vs 4.3% in control eyes, odds ratio for Marfan syndrome in the presence of iris transillumination defects = 7.2). Ectopia lentis was only found in Marfan syndrome eyes (25 Marfan syndrome patients, 49% with available data, bilateral in 68%). CONCLUSION: Iris transillumination defects and ectopia lentis are characteristic ocular findings in children and adolescents with Marfan syndrome. Myopia is more common and corneal curvature, central corneal thickness, and visual acuity are reduced in Marfan syndrome eyes. Children with Marfan syndrome need regular comprehensive eye examinations to identify potential complications.

AB - Two series of fifteen novel thioxoflavonoids 2a-2h and 4a-4g were synthesized from corresponding flavonoids 1a-1h and 3a-3g by reacting with Lawesson's reagent, respectively. Their in vitro antiproliferative activities were evaluated on a panel of three human cancer cell lines (Hela, HCC1954 and SK-OV-3) using cell counting kit-8 (CCK-8) assay. The results showed that most of the target compounds exhibited moderate to good antiproliferative activities against the three human cancer cell lines. In particular, thioxoflavonoids 2f and 2g showed the strongest antiproliferative activity on all three human cancer cell lines with IC50 values ranging from 3.34 to 4.67 MUM, 4f showed the best antiproliferative activity on Hela cells (IC50 2.30 MUM), 2e showed the best antiproliferative activity on HCC1954 cells (IC50 2.13 MUM) and SK-OV-3 cells (IC50 2.33 MUM). The antiproliferative activities may be involved in their antioxidant activity, which can be speculated by their ability to scavenge free radicals and by their capacity of affecting key redox enzymes.

MATERIALS & METHODS: Intestinal tissue from preterm pigs, modeling preterm infants, was collected at birth and 5 days after gradual introduction of infant formula or bovine colostrum. The intestinal tissue was analyzed by reduced representation bisulfite sequencing and real-time qPCR. RESULTS: Relative to colostrum, formula increased bacterial epithelial adherence and lipopolysaccharide binding protein (LBP) expression, which was regulated by promoter methylation. Diet-dependent changes in DNA methylation and/or mRNA expression were related to innate immune response, hypoxia, angiogenesis and epithelial-mesenchymal transition pathways (e.g., TTC38, IL8, C3, HIF1A and VEGFR1). CONCLUSION: Epigenetic changes may mediate important effects of the first feeding on intestinal development in preterm neonates. PMID- 29587529 TI - Laceioside, a new cycloartane saponin from Astragalus tephrosioides Boiss. var. lacei (Ali) Kirchoff. AB - Phytochemical investigation of the aerial parts of Astragalus tephrosioides Boiss. var. lacei (Ali) Kirchoff. (Family Fabaceae) resulted in the isolation of a new cycloartane glycoside laceioside (1). The structure of the previously undescribed compound 1 was established as 16beta-acetyloxy-3-O-beta-d glucopyranosyloxy-cycloartan-11alpha,24xi, 25-triol. The structure elucidation of compound 1 was based primarily on 1D and 2D-NMR techniques including 1H and 13CNMR spectra, DEPT and by 2D COSY, HSQC and HMBC experiments. PMID- 29587530 TI - A multilevel examination of sleep, depression, and quality of life in people living with HIV/AIDS. AB - Sleep problems are prevalent in people living with HIV/AIDS; however, few studies examine how poor sleep affects mental health and quality of life longitudinally. A sample of people living with HIV/AIDS from a randomized trial ( N = 240; mean age = 47.18; standard deviation = 8.3; 71.4% male; 61.2% White) completed measures of depression (Montgomery-Asberg Depression Rating Scale), health related quality of life (AIDS Clinical Trial Group Quality of Life Measure), and life satisfaction (Quality of Life Inventory) at baseline and 4, 8, and 12 months. Controlling for time, condition, and relevant interactions, sleep problems significantly predicted worse outcomes over time ( ps < 0.001). Findings have implications for the importance of identifying and treating sleep problems in people living with HIV/AIDS to improve mental health and quality-of-life outcomes. PMID- 29587531 TI - Learning Curves and Timing of Surgical Trials: Robotic Kidney Transplantation with Regional Hypothermia. AB - PURPOSE: Outcomes of surgical procedures can be affected by multiple factors including surgical skill and learning curve (LC). These factors need to be considered for optimal timing of surgical trials. We used the LC cumulative summation (CUSUM) method to describe the number of cases associated with competency of a single surgeon learning the technique of robotic kidney transplantation (RKT). METHODS: Thirty-three patients underwent Vattikuti Urology Institute technique of RKT at a center that recently adopted this procedure (study group). Anastomoses times and short-term functional outcomes were compared with an established RKT program (reference group). LCs were evaluated using CUSUM analysis using target values from the reference group. RESULTS: Mean +/- standard deviation for console time, rewarming time (RWT), arterial anastomosis, venous anastomosis, and ureterovesical anastomosis times for the study group was 187 +/- 34.6 minutes, 58.03 +/- 17.81 minutes, 19.36 +/- 5.91 minutes, 21.97 +/- 6.78 minutes, and 22.55 +/- 4.24 minutes, respectively, significantly longer than reference group (p < 0.001 for all). Mean +/- standard deviation for serum creatinine at discharge and 1 month in the study group was 1.43 +/- 0.57 mg/dL and 1.23 +/- 0.35 mg/dL, respectively, similar to the reference group (p = 0.074 at discharge and p = 0.163 at 1 month). The LC was short, with competence achieved for RWT within 9, proficiency within 16, and mastery within 21 cases. Longer anastomosis times during the LC did not affect graft function. CONCLUSIONS: The LC of RKT is short, with improving skill up to 20-25 cases. The procedure is reproducible by surgeons experienced with open transplant and robotic surgery for other procedures, with comparable outcomes and low complication rates at a new center during adoption. PMID- 29587532 TI - An audit of the accuracy of medication information in electronic medical discharge summaries linked to an electronic prescribing system. AB - BACKGROUND: Poor communication of medication information to general practitioners when patients are discharged from hospital is a widely recognised problem. There has been little research exploring the accuracy of medication information in electronic discharge summaries (EDS) linked to hospital e-prescribing systems. OBJECTIVE: To evaluate the accuracy of medication lists and medication change information in EDS produced using an integrated e-prescribing and EDS system (where EDS discharge medication lists were imported from discharge e-prescription records, medication change information was manually entered, and medications were dispensed from paper copies of the patients' e-prescriptions). METHOD: Retrospective audit of EDSs for a random sample, representative of adult patients ( n = 87) discharged from a major teaching hospital. EDS medication lists were compared to pharmacist-verified paper discharge prescriptions (considered to be the most accurate discharge medication list) to identify discrepancies. EDS medication change information was compared to medication changes identified by comparing pharmacist-verified "Medication History on Admission" forms with pharmacist-verified paper discharge prescriptions. RESULTS: There were 85/87 (98%) EDSs that included a discharge medication list. Of these, 50/85 (59%) contained one or more medication list discrepancies (median 1, range 0-15). The most common discrepancy was omission of medication (58%); 84/131 (64%) discrepancies were considered clinically significant (risk of adverse outcome); 162/351 (46%) clinically significant medication changes were stated in the EDS; and 153/351 (44%) changes were both stated and included a reason. CONCLUSION: EDS discrepancies were common despite integration with e-prescribing. Eliminating paper prescriptions, enhancing e-prescribing/EDS functionality and involving pharmacists in EDS preparation may reduce discrepancies. PMID- 29587533 TI - A new triterpenoid saponin and a diterpene glucoside from the seeds of Orychophragmus violaceus. AB - One new triterpenoid saponin orychoside A (1) and one new diterpene glucoside orychoside B (12), together with eleven known compounds, were isolated from the seeds of Orychophragmus violaceus. The structures of the new compounds were elucidated on the basis of spectroscopic analysis. The known compounds were identified by comparison with data reported in the literature. All compounds were tested for their cytotoxic activities against the HepG2 and A549 cell lines in vitro. The new compound 1 exhibited potent cytotoxicity against the two cell lines with IC50 values of 7.13 and 8.77 MUM, respectively. Compounds 2, 5, 8 and 9 were found to possess obvious cytotoxicity.

PMID- 29587536 TI - Letter to the editor: On plurality and authorship in science. AB - Moffatt argues that the "plurality of distinct accounts of scientific authorship" necessitates caution in attempts to identify unethical authorship practices, and urges that considerations be given to establishing a "single consensus account of authorship." The revised International Committee of Medical Journal Editors (ICMJE) criteria do capture the essential features of authorship in terms of "intellectual contribution" and "responsibility and accountability," which would clearly demarcate academically legitimate authorship from the common misdemeanors of ghost writing and honorary authorship. However, plurality in the practice of science and credit-sharing culture at the ground would likely render universal adoption or compliance of a single consensus account of authorship untenable. PMID- 29587534 TI - Hypomethylation of GRHL3 gene is associated with the occurrence of neural tube defects. AB - AIM: To investigate the relationship between GRHL3 methylation and the etiology of neural tube defects (NTDs). MATERIALS & METHODS: Analyze data from a genome wide DNA methylation array. Targeted DNA methylation analysis was performed for 46 cases and 23 controls. At last, grhl3 overexpression and gene depletion experiments were conducted in zebrafish. RESULTS: Five hypomethylated CpGs were discovered in the methylation arrays performed on NTD cases. In a validation study, 15 hypomethylated CpGs were found and the overall methylation levels decreased in brain/spinal cord tissue from NTD cases. The knockdown and overexpression of grhl3 in zebrafish damaged embryonic convergent extension processes. CONCLUSION: Hypomethylation of GRHL3 in central nervous tissue is associated with NTDs, further supporting the importance of GRHL3 and methylation in proper neural tube closure. PMID- 29587537 TI - Preliminary Porcine In Vivo Evaluation of a Telerobotic System for Transurethral Bladder Tumor Resection and Surveillance. AB - INTRODUCTION: Transurethral resection of bladder tumors (TURBTs) can be a challenging procedure, primarily due to limitations in tooltip dexterity, visualization, and lack of tissue depth information. A transurethral robotic system was developed to revolutionize TURBTs by addressing some of these limitations. The results of three pilot in vivo porcine studies using the novel robotic system are presented and potential improvements are proposed based on experimental observations. MATERIALS AND METHODS: A transvesical endoscope with a mounted optically tracked camera was placed through the bladder of the swine under general anesthesia. Simulated bladder lesions were created by injecting HistoGel processing gel mixed with blue dye, transabdominally, into various locations in the bladder wall under endoscopic visualization. A 7-degree-of freedom (DoF) robot was then used for transurethral resection/ablation of these simulated tumors. An independent 2-DoF distal laser arm (DLA) was deployed through the robot for laser ablation and was assisted by a manually controlled gripper for en bloc resection attempts. RESULTS: Lesions were created and ablated using our novel endoscopic robot in the swine bladder. Full accessibility of the bladder, including the bladder neck and dome, was demonstrated without requiring bladder deflation or pubic compression. Simulated lesions were ablated using the holmium laser. En bloc resection was demonstrated using the DLA and a manual grasper. CONCLUSION: Feasibility of robot-assisted en bloc resection was demonstrated. Main challenges were lack of depth perception and visual occlusion induced by the transvesical endoscope. Recommendations are given to enhance robot assisted TURBTs. Lessons learned through these pilot swine studies verify the feasibility of robot-assisted TURBTs while informing designers about critical aspects needed for future clinical deployment. PMID- 29587538 TI - Conducting participatory photography with children with disabilities: a literature review. AB - PURPOSE: This review summarized studies that used participatory photography with children with disabilities, including those with communication impairments, and described modifications made to the methodology to facilitate their participation in qualitative research. METHODS: In the fall of 2016, we searched Psycinfo (OVID), ERIC, CINAHL and Web of Science to identify studies that used participatory photography with children with disabilities. The search was repeated in January 2018 to retrieve any new publications. The first author extracted data that described the characteristics of each study and the modifications used. RESULTS: Of the 258 articles identified, 19 met inclusion criteria. Participants ranged from 4-21 years old and had a variety of disabilities. Study topics included education, leisure activities and adulthood. Researchers modified participatory photography to enhance accessibility by: modifying cameras; providing individual training; teaching consent through role play; allowing children to direct adults to take photographs; including additional forms of media; using diaries and questionnaires; providing individual interviews with simplified questions; using multiple forms of communication; and modifying how photographs are shared. CONCLUSIONS: Participatory photography can be an effective method for studying the lived experiences of children with disabilities, particularly those with communication impairments. Methodological modifications can enhance the accessibility of this approach for this population. Implications for Rehabilitation Participatory photography may be an effective qualitative research method for learning about the perspectives and experiences of children with disabilities on a wide array of topics. There are many specific modifications that researchers can use to support the inclusion of children with disabilities in participatory photography research. The findings of studies that use participatory photography methodology may provide rehabilitation professionals with important insights into the lives of children with disabilities. PMID- 29587539 TI - Green approach to the extraction of major capsaicinoids from habanero pepper using near-infrared, microwave, ultrasound and Soxhlet methods, a comparative study. AB - A simple method for the extraction of two major capsaicinoids from habanero peppers, using near-infrared irradiation, microwave irradiation or ultrasound as the energy source and ethanol as the solvent, was compared with Soxhlet extraction. The extraction processes were monitored by gas chromatography/mass spectrometry. The new processes offer better overall yields and a higher ratio of capsaicin to dihydrocapsaicin than Soxhlet extraction. The physical effect of the different energy sources on the peppers was determined using scanning electron microscopy. Extraction of capsaicin and dihydrocapsaicin using near-infrared irradiation, which has not been previously reported, was shown to be a simple and efficient alternative extraction procedure. PMID- 29587540 TI - Risk of recurrent shoulder dystocia: are we any closer to prediction? AB - OBJECTIVE: To determine the incidence and risk factors for recurrent shoulder dystocia in women. METHODS: We searched Medline, Pubmed, Embase, and CINAHL for relevant articles in English and French from 1980 to February 2018 that described risks of recurrent shoulder dystocia undergoing a trial of labour in subsequent pregnancies. A total of 684 articles were found, of which 13 were included as they met criteria. We extracted data on study characteristics, incidence of recurrent shoulder dystocia, degree of neonatal injury, and presence of known risk factors. RESULTS: There was a wide variation in the incidence of shoulder dystocia in subsequent pregnancies from 1-25%. The largest cohort reported a risk of 13.5%. The most important risk factor for recurrent shoulder dystocia is an increase in birthweight in the subsequent pregnancy compared to the index pregnancy (OR 7-12). Prolonged second stage, instrumental delivery, maternal diabetes, increased maternal BMI, and severe neonatal morbidity in the index pregnancy were also associated with an increased risk of recurrent shoulder dystocia. However, many of these risk factors were present in women who did not have a recurrent shoulder dystocia. In addition, women with recurrent shoulder dystocia rarely had identifiable risk factors, other than the history of previous shoulder dystocia. Sample sizes were low as most studies are single centre, retrospective cohorts with low rates of subsequent pregnancy and vaginal birth as many women may have elected to have a caesarean section in subsequent pregnancies or were lost to follow up. There was a high rate of reporting bias and heterogeneity, prohibiting formal meta-analyses. CONCLUSION: Recurrent shoulder dystocia is an unpredictable obstetric complication with potentially devastating consequences. Individual assessment and thorough counselling should be offered to women contemplating a subsequent planned vaginal birth with specific attention paid to those women where the estimated birthweight is >4000 g or greater than in the index pregnancy. PMID- 29587541 TI - Effect of Holder pasteurization on macronutrients and immunoglobulin profile of pooled donor human milk. AB - OBJECTIVE: The objective of this study was to study the effect of Holder pasteurization on macronutrients and immunoglobulin profile of pooled donor human milk. METHODS: This descriptive study was conducted in a Human Milk Bank of a tertiary care teaching institute in south India. Thirty random paired pooled donor human milk samples (before and after pasteurization) were analyzed for macronutrients (protein, fat, carbohydrates) using infrared spectroscopy. Similarly, immunoglobulin profile (IgA and IgG) before and after pasteurization was quantified using ELISA. RESULTS: The mean values of protein, fat, and carbohydrates in pooled donor milk pre-pasteurization were 1.6, 3.6, and 6.1 g/dl compared with post-pasteurization values 1.4, 2.7, and 5.9 g/dl, respectively. Pasteurization reduced protein, fat, and energy content of pooled donor milk by 12.5%, 25%, and 16%, respectively. However, carbohydrates were not significantly reduced. Pasteurization decreased IgA by 30% and IgG by 60%. CONCLUSION: Holder pasteurization of pooled donor human milk decreases protein, fat, and energy content and also reduces the levels of IgA and IgG. PMID- 29587542 TI - Effects of maternal folic acid supplementation on airway remodeling and allergic airway disease development. AB - OBJECTIVE: Maternal folic acid supplementation has been recommended prior to and during the first trimester of pregnancy to reduce the risk of infant neural tube defects. However, an uncertain relationship between folic acid supplementation during pregnancy and development of childhood asthma exists. Recent data show a methyl donor-rich diet could increase the risk of developing allergic airway disease through DNA methylation and aberrant gene transcription. This study evaluated the effect of folic acid supplementation during pregnancy on airway remodeling and allergic airway disease vulnerability in a mouse asthma model. METHODS: BALB/c mice were divided into four groups according to gestational folic acid supplementation and postnatal ovalbumin (OVA) exposure: Group 1 (whole pregnancy folic acid supplementation + OVA-exposed group), Group 2 (first gestational week folic acid supplementation + OVA-exposed group), Group 3 (no folic acid supplementation + OVA-exposed group), and Group 4 (control group). Offspring were sacrificed on day 45 for immunohistological and ultrastructural tests. RESULTS: In OVA challenged groups, folic acid supplementation led to a thicker epithelial and subepithelial smooth muscle layer than in the unsupplemented group. Moreover, folic acid supplementation during whole pregnancy (Group 1) was associated with a thicker epithelial and subepithelial smooth muscle layer than folic acid supplementation during the first week of pregnancy (Group 2), suggesting a duration-response relationship. Electron microscopic imaging revealed that structural changes including the loss of epithelial integrity, thickening of basement membrane, and subepithelial fibrosis were more prominent in the folic acid supplementation groups. CONCLUSIONS: This study suggested that maternal folic acid supplementation during pregnancy affects airway remodeling and increases the allergic responses induced by ovalbumin challenge in offspring. In addition, the effect size increased as the duration and cumulative dose increased. PMID- 29587543 TI - Iron overdose epidemiology, clinical features and iron concentration-effect relationships: the UK experience 2008-2017. AB - BACKGROUND: Iron poisoning is potentially serious, but mortality has fallen worldwide since implementation of pack size and packaging restrictions, and changes in iron use during pregnancy. The management of individual cases of overdose remains problematic due to uncertainty about indications for antidote. We examine the epidemiology of iron overdose in hospital cases referred to the UK National Poisons Information Service (NPIS) and evaluate the toxicokinetics of iron in patients ingesting only iron preparations. METHODS: Anonymized hospital referral patient data from the NPIS database were collated for the period 1 January 2008 to 31 July 2017. Information was extracted, where recorded, on type of ingestion [iron alone (single), or combined with other agents (mixed)], reported dose, iron salt, timed iron concentrations and symptoms. In single-agent ingestions, the relationships between reported elemental iron dose, early concentrations (4-6 h), and symptoms were evaluated in teenagers and adults (>=13 years) and children (<=12 years) using standard statistical techniques (correlation and unpaired nonparametric comparisons). In those patients with sufficient sample points (three or more), a simple kinetic analysis was conducted. RESULTS: Of 2708 patients with iron overdoses referred by UK hospitals for advice during the 9.7 years study period, 1839 were single-agent ingestions. There were two peaks in age incidence in single-agent exposures; 539/1839 (28.4%) were <6 years (54.1% males) while 675/1839 (36.7%) were between 13 and 20 years (91% females), the latter a substantial excess over the proportion in the totality of hospital referrals to the NPIS in the same period (13-20 years: 23,776/144,268 16.5%; 67.5% female) (p < .0001 overall and for female %). In 475 teenagers and adults and 86 children, with at least one-timed iron concentration available, there was no correlation between stated dose and iron concentration measured 4-6 h post-ingestion. Observed peak iron concentrations were not related to reported symptoms in adults. Initial iron concentrations were significantly higher in 30 patients (25 adults, 5 children) who received desferrioxamine (DFO) compared to those that did not [no DFO: mean 63.8 MUmol/L (95% CI 62.1-65.6), median 64; DFO: mean 78.5 MUmol/L (95% CI 69.2-87.7), median 78.1; Mann-Whitney p < .0018). No significant differences in symptoms were observed pre-treatment between DFO-treated and untreated groups. No patients died in this cohort. CONCLUSION: Single-agent iron exposures reported from UK hospitals were most common in children <5 years and young people aged 13-20 years. Poisoning with organ failure was not identified and there were no fatalities. No correlations were observed between reported iron doses and early concentrations, or between iron concentrations and symptoms in this cohort of mild-to-moderate poisoning. PMID- 29587544 TI - Ferula pseudalliacea induces apoptosis in human colorectal cancer HCT-116 cells via mitochondria-dependent pathway. AB - Ferula species have diverse biological functions. This study set out to investigate the anti-proliferative effects of methanolic extract of F. pseudalliacea against human colon cancer HCT-116 cell line. Cytotoxic effects of F. pseudalliacea on HCT-116 cells was estimated by 3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyltetrazolium (MTT) assay. Real-time polymerase chain reaction (PCR) and Western blot were employed to analyze BAX and Bcl2 expression. Cell cycle analysis and apoptosis were conducted using flowcytometry and Annexin V/ propidium iodide (PI) staining. Rhodamine 123 staining and enzyme-linked immunosorbent assay (ELISA) assay were employed to quantify the mitochondria membrane potential (MMP) and caspase 3 activity, respectively. F. pseudalliacea markedly decreased HCT-116 cells viability. The gene and protein expression of BAX were increased, whereas Bcl-2 was decreased in F. pseudalliacea treated cells. F. pseudalliacea induced apoptosis via promotion of cell cycle arrest, caspase 3 activation, and destruction of MMP. These results demonstrate that F. pseudalliacea extract is able to induce apoptosis in HCT-116 cells mainly by activation of the mitochondrial pathway. PMID- 29587546 TI - Uncovering the regional localization of inhaled salmeterol retention in the lung. AB - Treatment of respiratory disease with a drug delivered via inhalation is generally held as being beneficial as it provides direct access to the lung target site with a minimum systemic exposure. There is however only limited information of the regional localization of drug retention following inhalation. The aim of this study was to investigate the regional and histological localization of salmeterol retention in the lungs after inhalation and to compare it to systemic administration. Lung distribution of salmeterol delivered to rats via nebulization or intravenous (IV) injection was analyzed with high-resolution mass spectrometry imaging (MSI). Salmeterol was widely distributed in the entire section at 5 min after inhalation, by 15 min it was preferentially retained in bronchial tissue. Via a novel dual-isotope study, where salmeterol was delivered via inhalation and d3-salmeterol via IV to the same rat, could the effective gain in drug concentration associated with inhaled delivery relative to IV, expressed as a site-specific lung targeting factor, was 5-, 31-, and 45-fold for the alveolar region, bronchial sub-epithelium and epithelium, respectively. We anticipate that this MSI-based framework for quantifying regional and histological lung targeting by inhalation will accelerate discovery and development of local and more precise treatments of respiratory disease. PMID- 29587547 TI - Silver nanoparticles improve structural stability and biocompatibility of decellularized porcine liver. AB - No ideal cross-linking agent has been identified for decellularized livers (DLs) yet. In this study, we evaluated structural improvements and biocompatibility of porcine DLs after cross-linking with silver nanoparticles (AgNPs). Porcine liver slices were decellularized and then loaded with AgNPs (100 nm) after optimization of the highest non-toxic concentration (5 ug/mL) using Human hepatocellular carcinoma (HepG2) and EAhy926 human endothelial cell lines. The cross-linking effect of AgNPs was evaluated and compared to that of glutaraldehyde and ethyl carbodiimide hydrochloride and N-hydroxysuccinimide. The results indicated that AgNPs improved the ultra-structure of DLs' collagen fibres with good porosity and increased DLs' resistance against in vitro degradation with good cytocompatibility. AgNPs decreased the host inflammatory reaction against implanted porcine DL slices in vivo and increased the polarization of M2 macrophages. Thus, structural and functional improvements of Porcine DLs could be achieved using AgNPs. PMID- 29587548 TI - In reply to 'early tracheostomy in traumatic brain injury- conundrum continues...'. PMID- 29587545 TI - Puerarin-loaded PEG-PE micelles with enhanced anti-apoptotic effect and better pharmacokinetic profile. AB - Puerarin (PUE) is the most abundant isoflavonoid in kudzu root. It is widely used as a therapeutic agent for the treatment of cardiovascular diseases. However, the short elimination half-life, poor-bioavailability, and acute intravascular hemolysis of PUE are the main obstacles to its widespread clinical applications. Whereas PEG-PE micelles possess the ability to release medicine slowly, enhance the cellular uptake of drugs and improve their biocompatibility. Therefore, it was aim to fabricate puerarin-loaded PEG-PE (PUE@PEG-PE) micelles to improve the pharmaceutical properties of drugs. It can be observed from the TEM images that PUE@PEG-PE micelles appeared obvious core-shell structure and remained well dispersed without aggregation and adhesion. PUE was successfully embedded in the core of PEG-PE micelles, which was confirmed by FT-IR and 1H NMR spectra. In vitro studies showed that PUE@PEG-PE micelles exhibited a sustained release behavior in pH 7.4 PBS buffer and decreased hemolysis rate of PUE. Compared with PUE, PUE@PEG-PE micelles showed a 3.2-fold increase in the half-life of PUE and a 1.58-fold increase in bioavailability. In addition, the PUE@PEG-PE micelles exerted enhanced protective effect against isoprenaline-induced H9c2 cells apoptosis compared with PUE, as evident by decreased percentage of Hoechst positive cells, Caspase 3 activity, Bax expression, and increased Bcl-2 expression. Notably, the PEG-PE micelles exhibited favorable cellular uptake efficiency on H9c2 cells, and this may account for their enhanced anti-apoptotic effect of the incorporated drug. Altogether, the PUE@PEG-PE micelles were not only able to control the drug release but also offered promise to enhance the pharmacokinetic and pharmacodynamic potential of PUE. PMID- 29587549 TI - The importance of the rehabilitation program following an internal hemipelvectomy and reconstruction with limb salvage - gait analysis and outcomes: a case study. AB - BACKGROUND: Chondrosarcomas account for approximately 20% of bone sarcomas, with the most common site being the lower limb. Hemipelvectomies that involve hindquarter amputation have previously been the treatment of choice for pelvic tumors. However, with advances in chemotherapy, radiotherapy, imaging and surgical techniques more patients are now being treated with limb salvage surgery. The rehabilitation outcomes following an internal hemipelvectomy have not been well identified and there is currently little, if any, gait analysis data on rehabilitation following hemipelvectomy in limb salvage patients. CASE DESCRIPTION: A 53-year-old male underwent an internal hemipelvectomy with limb salvage followed by a 2-year rehabilitation program. The aim of this case study is to describe temporal and spatial parameters, metabolic energy expenditure and joint kinematics of a patient with an internal hemipelvectomy who underwent a wide excision of a chondrosarcoma followed by intensive rehabilitation. OUTCOMES: Walking speed (1.6 m/s), stride length (1.7 m), stride width (0.13 m) and good symmetry in step length (right 0.85 m and left data 0.80 m) and stance time (right 62% and left 59%) indicate a walking pattern similar to the asymptomatic able bodied. Oxygen consumption was 16.6 ml/kg/min and oxygen cost 0.17 ml/kg/m. DISCUSSION: Following the intensive 2-year rehabilitation program this patient's gait pattern was similar to a control group with no statistically significant difference in the movement of the left and right knee and ankle joints. Some differences were identified against the control group in respect of the movement of the pelvis and hips, but this is partly to be expected. This case study highlights the functional outcomes that can be achieved following limb salvage surgery with intensive rehabilitation and a high level of motivation from the individual. Implications for rehabilitation Advancements in chemotherapy, imaging and surgical techniques have allowed more patients to be treated with internal hemipelvectomy. The rehabilitation outcomes following an internal hemipelvectomy have not been well identified and there is little gait analysis data. This case study highlights the functional outcomes that can be achieved following limb salvage surgery with intensive rehabilitation and motivation from the individual. Rehabilitation following internal hemipelvectomy should include goal setting, lymphoedema management, physiotherapy and an exercise program.

PMID- 29587551 TI - Predictors of hearing loss self-management in older adults. AB - PURPOSE: To determine the factor structure of a clinical tool for the assessment of hearing loss self-management, and to identify predictors of the total score on the assessment and the extracted factor scores. MATERIALS AND METHODS: Hearing loss self-management assessments were conducted with 62 older adults. The factor structure of the assessment was determined by exploratory factor analysis. Multiple linear regression analyses identified significant contributors to the total score and to each of the extracted factors. RESULTS: Three factors were identified, each representing a distinct domain of hearing loss self-management: Actions, Psychosocial Behaviours, and Knowledge. The most common significant predictor was hearing health care experience, which predicted self-management overall and in the Actions and Knowledge domains. Health literacy predicted hearing loss self-management overall and in the Psychosocial Behaviours domain. Actions were additionally predicted by hearing aid self-efficacy and gender, Psychosocial Behaviours by health locus of control, and Knowledge by age. CONCLUSIONS: The results of the factor analysis suggested that hearing loss self management is a multidimensional construct. Each domain of hearing loss self management was influenced by different contextual factors. Subsequent interventions to improve hearing loss self-management should therefore be domain specific and tailored to relevant contextual factors. Implications for rehabilitation Hearing loss is a chronic health condition that requires on-going self-management of its effects on everyday life. Hearing loss self-management is multidimensional and encompasses the domains of Actions, Psychosocial Behaviours, and Knowledge. Different contextual factors influence each hearing loss self management domain, including previous experience receiving hearing health care services, health literacy, hearing aid self-efficacy, health locus of control, age, and gender. Audiological rehabilitation programs should thus ensure that interventions to improve hearing loss self-management are domain- and context specific. PMID- 29587552 TI - Work disability negotiations: supervisors' view of work disability and collaboration with occupational health services. AB - PURPOSE: To introduce the Finnish practice of collaboration aiming to enhance work participation, to ask supervisors about its reasons and usefulness, to study supervisors' needs when they face work disability, and to compare the experiences of supervisors whose profiles differ. MATERIALS AND METHODS: An online questionnaire based on the Finnish practice of collaboration between supervisor and occupational health services (OHS) went to supervisors in six public and private organizations. A total of 254 supervisors responded, of whom, 133 (52%) had collaborated in work disability negotiations, representing a wide variety with differing professional profiles. RESULTS: In their role of managing work disability, supervisors appeared to benefit from three factors: an explicit company disability management (DM) policy, supervisors' training in DM, and collaboration with OHS. Reasons for work disability negotiations were long or repeated sick-leaves and reduced work performance. Expectations for occupational health consultations focused on finding vocational solutions and on obtaining information. Supervisors assessed the outcomes of collaboration as both vocational and medical. Supervisors with differing professional profiles prioritized slightly different aspects in collaboration. CONCLUSIONS: Collaboration with OHS is an important option for supervisors to enhance work modifications and the work participation of employees with work disability. Implications for Rehabilitation Work disability negotiation between supervisor, employee, and occupational health services (OHS) is an effective method to enhance work participation. Collaboration with occupational health can advance work modifications and also lead to medical procedures to improve work performance. Supervisor training, companies' explicit disability management policy, and collaboration with OHSs all advance employee's work participation. Collaboration with OHSs may serve as training for supervisors in their responsibility to support work participation. PMID- 29587553 TI - A fatality following difluoroethane exposure with blood and tissue concentrations. PMID- 29587554 TI - Irreversible profound symptomatic bradycardia requiring pacemaker after tizanidine/loxoprofen combination therapy: a case report. AB - A 37-year-old man suffered irreversible profound symptomatic bradycardia requiring a pacemaker 3 days after beginning tizanidine/loxoprofen combination therapy for neck pain. This combination therapy is prescribed frequently for joint pain; however, combining loxoprofen with tizanidine could increase the risk of symptomatic bradycardia that is both permanent and severe. Similar cases have not been reported. This case suggests that tizanidine should be used cautiously when combined with loxoprofen, and drug interaction screening should be performed.

Current smoking cessation aids include nicotine replacement therapies, bupropion, and varenicline. Although more than 70% of smokers express a desire to quit, fewer than 3% remain abstinent for more than one year, highlighting a critical need for more efficacious smoking cessation treatments. Areas covered: The authors discuss the rationale, preclinical and clinical development of varenicline for smoking cessation. They cover the development of varenicline as a partial agonist at alpha4beta2 receptors, the primary neural substrate for nicotine reward. Then, they discuss evidence from preclinical studies indicating varenicline's efficacy in blocking nicotine reward, followed by clinical trials demonstrating safety and efficacy in sustaining abstinence in smokers. Finally, they cover post-market surveillance, including caution in heavy machine operators, putative cardiovascular risk, and the repealed warning for adverse neuropsychiatric events. Expert opinion: Varenicline development was based on strong theoretical rationale and preclinical evidence. Clinical studies indicate that varenicline is safe and more effective in sustaining abstinence than placebo, bupropion or nicotine replacement therapies. However, given that continuous abstinence rates across studies remain low (18 ~ 30% with varenicline; 4 ~ 10% with placebo), novel and more effective medications targeting other nicotinic or glutamate receptors for smoking cessation are required.

AB - Polycystic kidney disease is characterized by the progressive development of kidney cysts and declining renal function with frequent development of cysts in other organs including the liver. The polycystic kidney (PCK) rat is a rodent model of polycystic liver disease that has been used to study hepatorenal disease progression and evaluate pharmacotherapeutic interventions. Biomarkers that describe the cyst progression, liver impairment, and/or hepatic cyst burden could provide clinical utility for this disease. In the present study, hepatic cyst volume was measured by magnetic resonance imaging in PCK rats at 12, 16, and 20 weeks. After 20 weeks, Sprague Dawley (n = 4) and PCK (n = 4) rats were sacrificed and 42 bile acids were analyzed in the liver, bile, serum, and urine by liquid chromatography coupled to tandem mass spectrometry. Bile acid profiling revealed significant increases in total bile acids (molar sum of all measured bile acids) in the liver (13-fold), serum (6-fold), and urine (3-fold) in PCK rats, including those speciated bile acids usually associated with hepatotoxicity. Total serum bile acids correlated with markers of liver impairment (liver weight, total liver bile acids, total hepatotoxic liver bile acids, and cyst volume [ r > 0.75; P < 0.05]). Based on these data, serum bile acids may be useful biomarkers of liver impairment in polycystic hepatorenal disease.

AB - BACKGROUND AND OBJECTIVES: We evaluated the location and structure of the fibrous sheath formed after the placement of tunneled, cuffed hemodialysis catheters in large animals, 70 kg pigs. We focused on describing the location of the fibrous sheath in relation to the catheter. Its location explains the fibrous sheath's ability to cause catheter dysfunction by covering the catheter exit ports located at the catheter's tip. DESIGN: We used three animals. Each animal had a tunneled, cuffed, 15-French diameter hemodialysis catheter placed in the external jugular vein, with the tip at the junction of the superior vena cava and the right atrium. Two animals were sacrificed at 5 weeks and one animal at 17 weeks after catheter placement. The catheter and surrounding tissues were removed in one block. The fibrous sheath was dissected and longitudinally cut along the catheter to evaluate its extension in relation to the catheter. Relevant portions of the fibrous sheath were sent for pathology examination. RESULTS: The fibrous sheath covered the catheter in its entire length and circumference. It started at the entry site and continued without any interruption along the entire length of the catheter, including the tip. Its average thickness is 1 mm and has an inner cellular/inflammatory layer comprising lymphocytes, plasma cells, neutrophils, macrophages, multinucleated giant cells, and spindled cells and an outer layer comprising a mixture of collagen and fibroblasts. CONCLUSION: Our model showed that the fibrous sheath forms around all catheters and covers them in their entire length and circumference without any gaps.

AB - Background Oxaliplatin is a third-generation chemotherapeutic agent that is commonly used to treat metastatic digestive tumors; however, one of the main limiting complications of oxaliplatin is painful peripheral neuropathy. The purpose of this study was to examine the underlying mechanisms by which mammalian target of rapamycin (mTOR) and its signal are responsible for oxaliplatin-evoked neuropathic pain. Methods Neuropathic pain was induced by intraperitoneal injection of oxaliplatin in rats. ELISA and Western blot analysis were used to examine the levels of pro-inflammatory cytokines (including interleukin (IL) 1beta, IL-6, and tumor necrosis factor (TNF)-alpha) and the expression of mTOR signal pathway. Results Oxaliplatin increased mechanical and cold sensitivity as compared with control animals ( P < 0.05 vs. control rats). Oxaliplatin also amplified the expression of p-mTOR and mTOR-mediated phosphorylation of p70 ribosomal S6 protein kinase 1 and 4E-binding protein 1 in the lumbar dorsal root ganglion. Blocking mTOR using rapamycin attenuated peripheral painful neuropathy observed in oxaliplatin rats ( P < 0.05 vs. vehicle control). This inhibitory effect was accompanied with decreases of IL-1beta, IL-6, and TNF-alpha. In addition, inhibition of phosphatidylinositide 3-kinase (p-PI3K) attenuated the expression of p-mTOR and the levels of pro-inflammatory cytokines in oxaliplatin rats, and this further attenuated mechanical and cold hypersensitivity. Conclusions The data revealed specific signaling pathways leading to oxaliplatin induced peripheral neuropathic pain, including the activation of PI3K-mTOR and pro-inflammatory cytokine signal. Inhibition of these pathways alleviates neuropathic pain. Targeting one or more of these molecular mediators may present new opportunities for treatment and management of neuropathic pain observed during chemotherapeutic application of oxaliplatin. PMID- 29587561 TI - Infant follow-up postdelivery from a hepatitis C viral load positive mother. AB - OBJECTIVE: The primary current recommendation for infant follow-up postdelivery from a hepatitis C virus (HCV) viral load positive mother is to evaluate for the presence of antibody at or after 18 months of age. Our study objective was to analyze compliance with this recommendation for postdelivery infant HCV screening at our institution among a cohort of infants delivered from HCV viral load positive mothers. METHODS: Starting 1 January, 2015, a prospective database was developed for all pregnancies that involved mothers with a positive HCV viral load during pregnancy. This short report describes the infant follow-up for deliveries through 30 June, 2016. At hospital discharge, all neonates were given follow-up pediatric appointments and mothers were supplied the date and time of the appointment along with the pediatric group name, office directions, and phone number. Statistics involved simple percentages with Poisson binomial 95% confidence intervals. RESULTS: A total of 127 newborns were delivered of HCV viral load positive mothers during the study period and 55 (43%, 95% CI 35-52%) attended their pediatric appointments and were still in follow-up. Regarding the 72 cases (57%, 95% CI 48-65%) not in follow-up, 24 (19%, 95% CI 13-27%) never presented to care and 48 (38%, 95% CI 29-47%) came to one or two visits shortly after delivery but were absent for further follow-up. CONCLUSIONS: These data demonstrate that follow-up at 18 months postdelivery from an HCV viral load positive mother occurs in less than half of the cases and alternative screening strategies should be evaluated. PMID- 29587562 TI - Correlation between umbilical arterial pH values and fetal vertebral artery Doppler waveforms at the beginning of the second stage of labor: a pilot prospective study. AB - OBJECTIVE: The aim of this study was to evaluate the association between umbilical arterial pH and fetal vertebral artery Doppler velocimetry waveforms measured at the beginning of the second stage of labor in physiological term pregnancies. METHODS: This was a prospective cohort study of 250 pregnancies. The resistance index, pulsatility index, and peak systolic velocity were measured. The relationship between the fetal Doppler and the umbilical arterial pH was evaluated. A simple linear regression and a general linear model were used to explore possible correlations of Doppler parameters with fetal and neonatal outcome adjusted for confundents. RESULTS: Umbilical arterial pH values were directly associated with vertebral artery pulsatility index. Fetuses with lower pulsatility index values were at increased risk of a subsequent diagnosis of pathological fetal heart rate tracing patterns (presence of decelerations or reduced variability according to FIGO criteria during the second stage of labor). We estimated a decrease in pulsatility index of 10% in those fetuses destined to show a pathological fetal heart rate tracing. CONCLUSION: Vertebral artery Doppler waveforms correlates with umbilical pH in normal pregnancies and is also a function of fetal heart rate patterns. If this proportional association would be demonstrated also for abnormal pH values, vertebral artery pulsatility index might be useful to evaluate fetal wellbeing in those cases of suspected hypoxia/academia. PMID- 29587563 TI - Predictive role of endothelin in left ventricular remodeling of chronic kidney disease. AB - BACKGROUND: In chronic kidney disease (CKD), endothelin-1 (ET-1) always increases and there are changes in cardiac ultrasonography. In the present study, we aimed at investigating the role of serum ET-1 in predicting cardiac complications in patients with CKD. METHODS: The level of serum ET-1 was measured by enzyme-linked immunosorbent assay (ELISA) and cardiac ultrasonography was performed in enrolled patients. Indexes of heart failure, such as left ventricular mass index, interventricular septum thickness and left ventricular end diastolic diameter, were measured in patients with CKD. RESULTS: In the present study, we found that the level of serum ET-1 was significantly correlated with left ventricular mass index, interventricular septum thickness and left ventricular end diastolic diameter (p < .001) in non-dialysis patients with CKD. CONCLUSIONS: The results of the present study indicated that the level of serum ET-1 is closely related to the cardiac complications of CKD and is a useful predictor of cardiac complication. PMID- 29587564 TI - Mirtazapine attenuates nicotine-seeking behavior in rats. AB - BACKGROUND: Nicotine is the major psychoactive component of tobacco. A number of pharmacological therapies have been evaluated, with poor results. Given the lack of success of these therapies, several authors have proposed alternative therapeutic strategies. One of these is the use of antidepressant drugs that may have a specific effect on the neural pathways or receptors underlying nicotine addiction. Mirtazapine is an antagonist of alpha2 NE receptors (noradrenergic receptor), 5-HT2A/C and 5-HT3 receptors and has demonstrated efficacy in reducing behavioral effects induced by drugs of abuse in human and animal models. AIMS: In this study, we evaluated the effect of chronic dosing of mirtazapine during extinction on the re-acquisition of nicotine-seeking in rodents. METHODS: We used the nicotine self-administration paradigm to assess the effects of mirtazapine on rats trained to self-administer nicotine under a pharmacological fixed-ratio schedule. Mirtazapine (30 mg/kg, i.p.) was administered during extinction. RESULTS: In this work, we found that mirtazapine attenuates the re-acquisition of nicotine-seeking responses. CONCLUSIONS: These results support the use of mirtazapine in clinical controlled trials as a useful therapy that prolongs and increases rates of preventing relapse into nicotine intake in humans. PMID- 29587565 TI - Fronto-limbic disconnection in patients with multiple sclerosis and depression. AB - BACKGROUND: The biological mechanism of depression in multiple sclerosis (MS) is not well understood. Based on work in major depressive disorder, fronto-limbic disconnection might be important. OBJECTIVE: To investigate structural and functional fronto-limbic changes in depressed MS (DMS) and non-depressed MS (nDMS) patients. METHODS: In this retrospective study, 22 moderate-to-severe DMS patients (disease duration 8.2 +/- 7.7 years), 21 nDMS patients (disease duration 15.3 +/- 8.3 years), and 12 healthy controls underwent neuropsychological testing and magnetic resonance imaging (MRI; 1.5 T). Brain volumes (white matter (WM), gray matter, amygdala, hippocampus, thalamus), lesion load, fractional anisotropy (FA) of fronto-limbic tracts, and resting-state functional connectivity (FC) between limbic and frontal areas were measured and compared between groups. Regression analysis was performed to relate MRI measures to the severity of depression. RESULTS: Compared to nDMS patients, DMS patients (shorter disease duration) had lower WM volume ( p < 0.01), decreased FA of the uncinate fasciculus ( p < 0.05), and lower FC between the amygdala and frontal regions ( p < 0.05). Disease duration, FA of the uncinate fasciculus, and FC of the amygdala could explain 48% of variance in the severity of depression. No differences in cognition were found. CONCLUSION: DMS patients showed more pronounced (MS) damage, that is, structural and functional changes in temporo-frontal regions, compared to nDMS patients, suggestive of fronto-limbic disconnection. PMID- 29587567 TI - Exploring moral problems and moral competences in midwifery: A qualitative study. AB - BACKGROUND: Most undergraduate midwifery curricula comprise ethics courses to strengthen the moral competences of future midwives. By contrast, surprisingly little is known about the specific moral competences considered to be relevant for midwifery practice. Describing these competences not only depends on generic assumptions about the moral nature of midwifery practice but also reflects which issues practitioners themselves classify as moral. OBJECTIVE: The goal of this study was to gain insight into the ethical issues midwives encounter in their daily work, the key competences and resources they consider indispensable to understand and deal with them, and to assess phenomena linked to moral distress. METHODS: We conducted individual semi-structured interviews with eight midwives and two other health professionals, varying in terms of years of experience and work setting. Interview transcripts were analyzed in an interdisciplinary research group, following thematic analysis. Ethical considerations: This study was not subject to approval according to the Swiss Law on Research with Humans. Participants were informed about the study goals and gave written informed consent prior to participation. RESULTS: External constraints limiting the midwife's and the patient's autonomy and resulting interpersonal conflicts were found to be the most relevant ethical issues encountered in clinical practice and were most often associated with moral distress. These conflicts often arise in the context of medical interventions midwives consider as not appropriate and situations in which less experienced midwives in particular observe a lack of both interprofessional communication and trust in their professional competence. Ethical issues related to late abortions or prenatal diagnostics and selective abortions were also frequently addressed, but many midwives involved had learned to cope with them. DISCUSSION: In the light of the ethical issues and factors contributing to phenomena of moral distress, an empirically grounded profile of moral competences is drafted. Curricular implications in the light of possible adaptations within undergraduate midwifery education are critically discussed. PMID- 29587568 TI - Metabolomics and Biomarker Discovery in Traumatic Brain Injury. AB - Traumatic brain injury (TBI) is one of the leading causes of disability and mortality worldwide. The TBI pathogenesis can induce broad pathophysiological consequences and clinical outcomes attributed to the complexity of the brain. Thus, the diagnosis and prognosis are important issues for the management of mild, moderate, and severe forms of TBI. Metabolomics of readily accessible biofluids is a promising tool for establishing more useful and reliable biomarkers of TBI than using clinical findings alone. Metabolites are an integral part of all biochemical and pathophysiological pathways. Metabolomic processes respond to the internal and external stimuli resulting in an alteration of metabolite concentrations. Current high-throughput and highly sensitive analytical tools are capable of detecting and quantifying small concentrations of metabolites, allowing one to measure metabolite alterations after a pathological event when compared to a normal state or a different pathological process. Further, these metabolic biomarkers could be used for the assessment of injury severity, discovery of mechanisms of injury, and defining structural damage in the brain in TBI. Metabolic biomarkers can also be used for the prediction of outcome, monitoring treatment response, in the assessment of or prognosis of post injury recovery, and potentially in the use of neuroplasticity procedures. Metabolomics can also enhance our understanding of the pathophysiological mechanisms of TBI, both in primary and secondary injury. Thus, this review presents the promising application of metabolomics for the assessment of TBI as a stand-alone platform or in association with proteomics in the clinical setting. PMID- 29587566 TI - Comparison of the efficacy and safety of non-steroidal anti-inflammatory drugs for patients with primary dysmenorrhea: A network meta-analysis. AB - Objective Non-steroidal anti-inflammatory drugs are used as first-line treatment of primary dysmenorrhea, but there has been no optimal clinical choice among non steroidal anti-inflammatory drugs yet. The present study was to assess the relative benefits of different common non-steroidal anti-inflammatory drugs for primary dysmenorrhea patients with a network meta-analysis. Methods Randomized controlled trials were screened by our criteria and included in the network meta analysis. Pain relief was considered as primary outcomes and adverse effect was supplied as a safety outcome, while additional rescue, assessment score, and pain intensity difference were secondary outcomes. All the indexes were evaluated with odds ratio or standardized mean difference. Surface under cumulative ranking curve result was used to calculate the ranking of each treatment. Results Totally, 72 randomized controlled trials of 5723 patients and 13 drugs were included in our study after screening. As for pain relief, all drugs except nimesulide, rofecoxib, and waldecoxib were superior to aspirin (odds ratio with 95% credible intervals, diclofenac: 0.28 (0.08, 0.86), flurbiprofen: 0.10 (0.03, 0.29), ibuprofen: 0.32 (0.14, 0.73), indomethacin: 0.21 (0.07, 0.58), ketoprofen: 0.25 (0.10, 0.64), mefenamic acid: 0.28 (0.09, 0.87), naproxen: 0.31 (0.15, 0.64), piroxicam: 0.15 (0.03, 0.59), and tiaprofenic acid: 0.17 (0.04, 0.63)). Aspirin also required additional rescue when compared with the majority of other drugs (flurbiprofen: 3.46 (1.15, 11.25), ibuprofen: 6.30 (2.08, 20.09), mefenamic acid: 7.32 (1.51, 37.71), naproxen: 2.66 (1.17, 6.55), and tiaprofenic acid: 9.58 (1.43, 94.63)). As for assessment of the whole treatment, ketoprofen, naproxen, rofecoxib, and ibuprofen got higher score significantly than placebo. In addition, ibuprofen performed better than placebo in pain intensity difference. Considering the safety, tiaprofenic acid and mefenamic acid were noticeable in low risk, and indomethacin revealed higher risk than any other drugs. According to the results of network analysis and surface under cumulative ranking curve, flurbiprofen was considered to be the best one among all the treatments in efficacy, and aspirin was worse than most of others. On the other hand, tiaprofenic acid and mefenamic acid were indicated as the safest drugs. Conclusion Considering the efficacy and safety, we recommended flurbiprofen and tiaprofenic acid as the optimal treatments for primary dysmenorrhea. PMID- 29587569 TI - Belonging and exclusion in the lives of young people with intellectual disability in small town communities. AB - In recent policies, it is assumed that communities welcome the inclusion of young people with intellectual disability. However, little is known about perspectives of young people themselves. This article reports on research that sought to address this gap. Young people with intellectual disability living in three Australian small town communities participated in pictorial mapping and photo rich methods to explore belonging and exclusion and links between these. Young people's feelings of comfort and safety with local spaces and people were important for their sense of belonging. Emplaced relationships with family and some friends were key to strong belonging, as were positive attachments to disability support workers and spaces. Social exclusion, either from particular places or more generally, was keenly felt. Young people's confidence, willingness to enter social spaces and relationships were magnified by ways that systems responded to their impairment, at worst fracturing their sense of feeling welcome and included. PMID- 29587570 TI - MUTYH and ORAI1 polymorphisms are associated with susceptibility to osteoarthritis in the Chinese Han population. AB - Background This study analyzed the associations between single nucleotide polymorphisms (SNPs) in the mutY homolog gene ( MUTYH) and the calcium release activated calcium channel gene ( ORAI1) with susceptibility to osteoarthritis in the Chinese Han population. Methods A total of 350 patients diagnosed with osteoarthritis from October 2013 to May 2016 were selected as the study group, together with 350 age- and gender-matched healthy controls. MUTYH SNP rs3219463 and ORAI1 SNPs rs712853, rs12313273, rs6486795, rs12320939, and rs7135617 were analyzed by Sanger sequencing. Serum MUTYH levels were measured by enzyme-linked immunosorbent assay. The relationship between SNPs in MUTYH and ORAI1 and osteoarthritis susceptibility was analyzed and compared with the level of serum MUTYH in the osteoarthritis and control groups. Results MUTYH rs3219463 G allele carriers (GG or GA genotypes) and ORAI1 rs7135617 T allele carriers had a higher risk of osteoarthritis than patients with other genotypes. The level of serum MUTYH in the study group was significantly higher than in the control group (22.05 +/- 19.14 ng/mL vs. 14.15 +/- 13.54 ng/mL). Conclusions MUTYH and ORAI1 SNPs are associated with osteoarthritis susceptibility in the Chinese Han population. PMID- 29587572 TI - Outcomes in Distressed Patients With Chronic Low Back Pain: Subgroup Analysis of a Clinical Trial. AB - Study Design Subgroup analysis of a controlled clinical trial. Background Current evidence suggests that people with chronic low back pain who are distressed may require different interventions than do those who are not distressed. Recently, the enhanced transtheoretical model intervention (ETMI) reported significant improvements in disability and pain and increased physical activity in patients with chronic low back pain compared to physical therapy as usual. Objectives To compare outcomes between ETMI and physical therapy interventions for participants with and without self-reported distress. Methods We tested the interaction between intervention (ETMI versus physical therapy) and distress status (using the Medical Outcomes Study 12-Item Short-Form Health Survey cut point), and performed between-group comparisons on 3 separate outcomes (disability, pain, and physical activity) at 3 and 12 months. Results In the ETMI group, 57 of 108 participants were considered distressed, versus 62 of 106 participants in the physical therapy group. The interaction between intervention and distress at 12 months was significant. Participants improved with both interventions, but the magnitude of change in distressed participants who received ETMI was larger than that in distressed participants who received physical therapy (mean +/- SD difference from baseline in disability of 6.1 +/- 6.1 in the ETMI group, compared with 3.4 +/- 6.7 in the physical therapy group). Conclusion The enhanced transtheoretical model intervention was significantly more effective than physical therapy in participants with distress. The trial was registered in ClinicalTrials.gov (NCT01631344). Level of Evidence Therapy, level 2b. J Orthop Sports Phys Ther 2018;48(6):491-495. Epub 27 Mar 2018. doi:10.2519/jospt.2018.7670. PMID- 29587573 TI - Physical Activity in Public Parks of High and Low Socioeconomic Status in Colombia Using Observational Methods. AB - BACKGROUND: Public parks are an important resource for the promotion of physical activity (PA). This is the first study in Colombia and the fourth in Latin America to describe the characteristics of park users and their levels of PA using objective measures. METHODS: A systematic observation assessed sex, age, and the level of PA of users of 10 parks in an intermediate-size city in Colombia, classified in low (5 parks) and high (5 parks) socioeconomic status (SES). A total of 10 daily observations were conducted, in 5 days of the week during 3 periods: morning, afternoon, and evening. RESULTS: In total, 16,671 observations were completed, recording 46,047 users. A higher number of users per park, per day, were recorded in high SES (1195) versus low SES (647). More men were observed in low-SES than high-SES parks (70.1% vs 54.2%), as well as more children were observed in low-SES than high-SES parks (30.1% vs 15.9%). Older adults in high-SES parks were more frequent (9.5% vs 5.2%). Moderate to vigorous PA was higher in low-SES parks (71.7% vs 63.2%). CONCLUSIONS: Low-SES parks need more green spaces, walk/bike trails, and areas for PA. All parks need new programs to increase the number of users and their PA level, considering sex, age group, and period of the week. PMID- 29587571 TI - Clinical opioids differentially induce co-internalization of MU- and delta-opioid receptors. AB - Opioid receptors play an important role in mediating the spinal analgesia. The MU opioid receptor is the major target of opioid drugs widely used in clinics. However, the regulatory mechanisms of analgesic effect and tolerance for clinical MU-opioid receptor-targeting opioids remain to be fully investigated. Previous studies showed the interaction of delta-opioid receptor with MU-opioid receptor to form the MU-opioid receptor/delta-opioid receptor heteromers that could be processed in the degradation pathway after delta-opioid receptor agonist treatment. Here, we showed that clinical MU-opioid receptor-targeting opioids, morphine, fentanyl, and methadone, but not tramadol, caused MU-opioid receptor co internalization with delta-opioid receptors in both transfected human embryonic kidney 293 cells and primary sensory neurons. Prolonged treatment of morphine led to MU-opioid receptor co-degradation with delta-opioid receptors. Furthermore, fentanyl and methadone, but not tramadol, induced the drug tolerance similar to morphine. Thus, the clinical MU-opioid receptor-targeting opioids including morphine, fentanyl, and methadone induce MU-opioid receptor co-internalization with delta-opioid receptors, which may be involved in the analgesic tolerance of these opioids. PMID- 29587574 TI - Clinical characteristics of infectious ulceration over tophi in patients with gout. AB - Objective The aim of this study was to investigate the clinical characteristics of infectious ulceration over tophi in patients with gout. Methods Participants were recruited from the First Affiliated Hospital of Wenzhou Medical University. The clinical characteristics of the patients and wound characteristics were recorded. Results Of the 38 enrolled patients, 18 were found to have infectious ulceration over tophi. Staphylococcus aureus was the most common pathogen and was identified in nine patients. Patients with infection were significantly older (69.6 vs. 60.1 years) and had a worse quality of life than those without infection. Patients with infection also had a significantly longer ulcer duration (125.6 vs. 54.2 days), larger ulcer size (2.47 vs. 1.99 cm2), a higher rate of tissue necrosis in the ulcer bed (55.6% vs. 20.0%), a lower rate of callus at the edge (27.8% vs. 70.0%), and a higher moisture level than did patients without infection. Additionally, patients with infection had significantly delayed wound healing (35.3 vs. 20.3 days) compared with patients without infection. Conclusions Older patients with a long ulcer duration and larger ulcer size are more susceptible to infection. Infection can lower patients' quality of life and delay wound healing.

AB - This article reports on a study of maternal sensitivity in 22 primiparous women and their infants from Rio de Janeiro, Brazil. Two semi-structured interviews were conducted, as well as videotaped naturalistic home observations of the dyads. A K-means cluster analysis was performed to examine patterns of risk in relation to maternal sensitivity. The results reveal that compared to the 15 mothers with higher sensitivity scores, the 7 mothers with lower sensitivity scores were characterized by lower educational levels, lower income, lower age, living in a slum, unplanned and unwanted pregnancies, and later onset of prenatal care. Whether father was resident did not appear to distinguish between the lower and higher sensitivity groups. The article concludes that the patterns of social contextual risk for Brazilian mothers showing less sensitive caregiving to their infants provide a clear direction for future research in this cultural context. PMID- 29587579 TI - The forearm basilic vein looped transposition fistula as a tertiary option for upper limb vascular access. AB - INTRODUCTION:: The forearm basilic vein can serve as an option for haemodialysis access but may not be possible in cases where the wrist arteries are unsuitable. In this setting, the forearm basilic vein can be used in a looped transposition with a brachial artery anastomosis. AIMS:: The aims of this study were to assess the outcome of forearm basilic vein looped transposition as an option for vascular access. MATERIAL AND METHODS:: Data from January 2007 to December 2010 were prospectively collected and analysed. Outcome measures were operative success, complications, maturation and primary and secondary patency following 5 years of follow-up. RESULTS:: From a total of 583 patients receiving autologous vascular access for haemodialysis, 24 (4.1%) underwent a forearm basilic vein looped transposition. The median age was 60 years (range, 27-80 years), with a slight male predominance (13 male:11 female). Mean follow-up was 34 months (1-60 months). Two patients died and other three were transplanted with subsequent fistula closure. All procedures were successful (100%); however, maturation failure occurred in one case (4.2%). No serious perioperative complications were observed. In two cases, we observed late false aneurysm formation requiring intervention. Primary patency at 1, 2, 3 and 5 years was the following: 77%, 62%, 21% and 10%, whereas secondary patency was the following: 81%, 71%, 61% and 32%, respectively. CONCLUSION:: Autologous forearm basilic vein looped transposition is an effective surgical procedure for the creation of access for haemodialysis. This may be a useful option in patients with compromised peripheral arterial diameter or flow and should be considered in patients with a suitable forearm basilic vein. PMID- 29587581 TI - Comparisons of Multilevel Modeling and Structural Equation Modeling Approaches to Actor-Partner Interdependence Model. AB - There are basically two modeling approaches applicable to analyzing an actor partner interdependence model: the multilevel modeling (hierarchical linear model) and the structural equation modeling. This article explains how to use these two models in analyzing an actor-partner interdependence model and how these two approaches work differently. As an empirical example, marital conflict data were used to analyze an actor-partner interdependence model. The multilevel modeling and the structural equation modeling produced virtually identical estimates for a basic model. However, the structural equation modeling approach allowed more realistic assumptions on measurement errors and factor loadings, rendering better model fit indices. PMID- 29587580 TI - Comparing two measures of maternal sensitivity: goodness of fit with a South African cultural context. AB - Recent scholarly insights show that nonverbal and subtle forms of sensitive responsiveness are more applicable to describing and assessing non-Western parent infant interactions than the more extraverted Western varieties of responsiveness. This paper examines whether the original Ainsworth scale (that does not specify particular manifestations of sensitivity) reveals different patterns of results in 50 South African mothers when compared to the Maternal Behavior Q-sort mini that assesses a more specified array of behaviors that may vary in their goodness of fit regarding the cultural context. The analysis reveals that there are key differences in the way the two measures operationalize maternal sensitivity, as seen in the incongruence of sensitivity ratings. The two measures are also shown to relate differently to maternal education and reflective functioning in this sample. The paper concludes that the Ainsworth sensitivity scale is better suited for use in the context of Alexandra Township, Johannesburg. PMID- 29587582 TI - Spironolactone to increase natriuresis in congestive heart failure with cardiorenal syndrome. AB - BACKGROUND: Signs and symptoms of volume overload are the most frequent reason for hospital admission in acute heart failure (AHF). Diuretics are mainstay treatment, but their optimal type and dose regimen remain unclear, especially in patients with cardiorenal syndrome. METHODS: This prospective study aimed to include 80 AHF patients with volume overload and cardiorenal syndrome. Through a 2 * 2 factorial design, patients were randomised towards (1) combinational treatment with acetazolamide and low-dose loop diuretics versus high-dose loop diuretics; and (2) open-label oral spironolactone 25 mg OD given upfront versus at discharge. Here reported are the results of the spironolactone treatment arm after complete follow-up of 34/80 patients (since the study was stopped because of slow recruitment). The primary study end-point was incident hypokalaemia (<3.5 mmol/L) or hyperkalaemia (>5.5 mmol/L). RESULTS: Serum potassium derangements were numerically less frequent in the upfront versus discharge spironolactone group, yet this result was underpowered due to incomplete study recruitment (hyperkalaemia: 6% vs. 11%; hypokalaemia: 13% vs. 28%, respectively; p-value = .270). Natriuresis after 24 h was higher in the upfront vs. discharge spironolactone group (314 +/- 142 vs. 200 +/- 91 mmol/L, respectively; p-value = .010). Relative change in plasma NT-proBNP level after 72 h was similar among both groups (-16 +/- 29% vs. -5 +/- 45%, respectively; p value = .393), with no difference in all-cause mortality (p-value = .682) or the combination of all cause mortality and heart failure readmission (p-value = .799). DISCUSSION: Spironolactone use upfront in AHF patients at high risk for cardiorenal syndrome is safe and increases natriuresis. PMID- 29587584 TI - ? PMID- 29587583 TI - Systematic Review and Meta-Analysis of Unplanned Reoperations, Emergency Department Visits and Hospital Readmission After Thyroidectomy. AB - BACKGROUND: Unplanned reoperation, emergency department (ED) visits, and hospital readmission following thyroid operations usually arise due to complications and are a source of frustration for both surgeons and patients. With the aim of providing insight important for the development of patient quality care improvement initiatives, the primary objective of this review was to evaluate the available literature systematically in order to determine the contemporary rates of reoperation, readmission, and ED visits following thyroid operations. A secondary study objective was to determine if there were any practices that showed promise in reducing the occurrence of these undesirable postoperative events. METHODS: This systematic review was conducted in accordance with the Preferred Reporting of Items for Systematic Reviews and Meta-Analyses protocols. Twenty-two studies were included in the systematic review. Meta-analysis was performed to obtain the weighted-pooled summary estimates of rates of reoperations, ED visits, and unplanned hospital readmission. Jackknife sensitivity analyses were performed for each data set. Finally, in order to detect the risk of publication bias and the small-study effect, funnel plot analysis was performed. RESULTS: The pooled rate estimate for reoperation was very low (0.6% [confidence interval (CI) 0.3-1.1%]). This was subject to publication bias because smaller studies tended to report lower rates of reoperation. The pooled rate of ED visits was 8.1% [CI 6.5-9.8%], while the pooled rate of hospital readmission from 19 studies was 2.7% [CI 2.1-3.4%]. Neck hematoma was the most common reason for reoperation, while postoperative hypocalcemia was the most common reason for hospital readmission. CONCLUSIONS: ED visits and hospital readmission after thyroidectomy are common, and there are several practices that can reduce their occurrence. Routine postoperative calcium and vitamin D supplementation may reduce rates of postoperative hypocalcemia, and avoiding postoperative hypertension may decrease the risk of neck hematoma development and the need for reoperation. Older age, thyroid cancer, dependent functional status, higher ASA score, diabetes, chronic obstructive pulmonary disease, steroid use, hemodialysis, and recent weight loss increase the risk of hospital readmission after thyroid surgery. By further identifying risk factors for reoperation, ED visits, and readmission, this review may assist practitioners in optimizing perioperative care and therefore reducing patient morbidity and mortality after thyroid operations.

AB - OBJECTIVES: The aim of our longitudinal study was to explore changes in HRQOL over a 6-month period and to identify factors associated with the HRQOL of HSCT recipients. METHOD: Our study comprised 191 HSCT patients; their data were collected before transplantation and at 30, 90, and 180 days posttransplantation. The Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) questionnaire was used to assess HRQOL.We also evaluated the patients' demographic characteristics and clinical histories to determine the relative contributions of these factors to HRQOL outcomes. RESULTS: Before HSCT, the patients reported a mean overall HRQOL of 110.31 (SD, 14.99); this reached a minimum of 105.07 (SD, 18.85) at day 30 after HSCT and increased steadily over time to 106.71 (SD, 18.34) at day 90 and 108.16 (SD, 18.34) at day 180 after HSCT.Compared with baseline, overall HRQOL changed with the mean of -5.24 (SE 1.55; P = .001), and -3.60 (SE 1.55; P = .022), respectively, at 30 days and 90 days after HSCT. Overall HRQOL returned to near pretransplant levels at 180 days after HSCT (SE 1.47; P = .146).Generalized estimating equation (GEE) models showed that household income (beta = 6.590; P < .001), transplant-related complications (beta = -6.101; P < .001), and patient age (beta = 0.243, P = .045) were associated with HRQOL. CONCLUSION: The patients' overall HRQOL was severely impaired in the early stages of posttransplantation, and patients experienced the worst HRQOL at 30 days. They had improved significantly by 180 days posttransplantation. We also found that household income, transplant-related complications, and age were independent predictors of early HRQOL.We therefore concluded that the HRQOL of HSCT patients in the early stages posttransplantation deserved more attention. PMID- 29587596 TI - Observing sensitivity in slums in Yemen: the veiled challenge. AB - This study represents the first video observation of parenting practices conducted in Yemen, where filming women is a taboo, and women are generally fully veiled, showing only their eyes, in the presence of strangers. A total of 62 mothers and children (aged 2-6 years) were filmed in their homes for 15 min during free interaction. The mothers' veils were not experienced as hampering the coding of sensitivity. Consistent with the socioeconomically deprived context, average sensitivity levels were low, but over 25% of mothers were rated as (very) sensitive. About half of the mothers elected to have their child do household chores, which in turn was related to lower levels of sensitivity. Observations revealed frequent looking at the camera. Almost half of the mothers verbally expressed insecurity about the videotaping, and a third expressed awareness of being filmed. Interestingly however, these behaviors were unrelated to Ainsworth ratings of maternal sensitivity. PMID- 29587597 TI - Ellagic acid as a potential antioxidant, alleviates methotrexate-induced hepatotoxicity in male rats. AB - BACKGROUND: Hepatotoxicity is one of the most life-threatening side-effects of Methotrexate therapy. Former studies highlighted the significance of oxidative stress in promoting Methotrexate-induced hepatotoxicity (MIH). Hence, the current study investigated the protective effect of Ellagic acid (EA), a poly-phenolic antioxidant, against MIH. METHODS: Twenty-eight male Wistar rats were grouped into four sets: group 1 (control), group 2 (injected intraperitoneally with 20 mg/kg of Methotrexate on the 9th day), group 3 (treated orally with 10 mg/kg/day of EA for 10 days and injected with Methotrexate on the 9th day) and group 4 (treated with EA for 10 days). Subsequently, biochemical and histopathological parameters were evaluated in serum samples and liver tissues. RESULTS: Methotrexate significantly increased activities of aminotransferases and ALP enzymes as well as levels of oxidative stress parameters in liver tissue. Likewise, Methotrexate decreased hepatic reduced glutathione level and activities of antioxidant enzymes. EA pre-treatment markedly attenuated the activities of aminotransferases and ALP, levels of oxidative stress parameters and augmented activities of antioxidant enzymes. Similarly, the remarkable protective effect of EA on liver has been confirmed by histological examination. CONCLUSION: In sum, the current study supports the hypothesis that EA may be used as a promising pre therapy to prevent the MIH. PMID- 29587598 TI - Economic Abuse as an Invisible Form of Domestic Violence: A Multicountry Review. AB - The predominant perception of intimate partner violence (IPV) as constituting physical violence can still dominate, particularly in research and media reports, despite research documenting multiple forms of IPV including sexual violence occurring between intimate partners and various forms of psychological and emotional abuse. One frequently hidden or "invisible" form of abuse perpetrated within intimate partner relationships is economic abuse, also referred to as financial abuse in much of the literature. While the links between gendered economic insecurity and economic abuse are emerging, there remains a lack of consistency about definitions within the United States and globally, as there is no agreed upon index with which to measure economic abuse. As such, the purpose of this article is to review and analyze the global literature focused on either economic or financial abuse to determine how it is defined and what measures are used to capture its prevalence and impact. The 46 peer-reviewed articles that met all inclusion criteria for analysis came from a range of countries across six continents. Our review found that there is growing clarity and consistency of terminologies being used in these articles and found some consistency in the use of validated measures. Since this research is in its "infancy," we need to have stronger collaborative efforts to use similar measures and terminology. Part of that collaborative effort is to consider how language and cultural differences may play a part in our understanding of economic abuse. PMID- 29587599 TI - Pathological and Clinical Pathological Changes Induced by Four-week, Repeated dose, Oral Administration of the Wood Preservative Chromated Copper Arsenate in Wistar Rats. AB - Chromated copper arsenate (CCA) is used as a wood preservative worldwide. Exposure to it may adversely affect human health. Some events have increased human exposure to CCA, including the Great East Japan Earthquake, which generated a large amount of lumber debris from CCA-treated woods. We elucidated the toxicity due to daily exposure to CCA over a 4-week period at doses of 0, 8, 40, and 80 mg/kg/day in Wistar Hannover rats. Chromium (Cr) and arsenic (As), but not copper, were detected in the plasma samples of rats treated with various doses of CCA. Males and females showed sedation, and males had poor body weight gain. The clinical pathologies observed in both sexes included hypochromic and microcytic anemia, hepatic and renal dysfunction, and changes in lipid and glucose levels. Histopathologically, males and females showed forestomach hyperkeratosis, mucosal epithelial hyperplasia in the small intestine, rectal goblet cell hypertrophy, and lipofuscin deposition in the proximal renal tubule. Females showed diffuse hepatocellular hypertrophy with increased 8-hydroxydeoxyguanosine levels. These results indicated that oral administration of CCA mainly affected hematopoietic, gastrointestinal, hepatic, and renal systems owing to the toxic effects of As and/or Cr. Major toxic effects were observed in both sexes receiving 40 and 80 mg/kg/day. PMID- 29587600 TI - Anticancer redox activity of gallium nanoparticles accompanied with low dose of gamma radiation in female mice. AB - Guided treatments with nanoparticles and radiotherapy are a new approach in cancer therapy. This study evaluated the beneficial antitumor effects of gamma radiation together with gallium nanoparticles against solid Ehrlich carcinoma in female mice. Gallium nanoparticles were biologically synthesized using Lactobacillus helveticus cells. Transmission electron microscopy showed gallium nanoparticles with size range of 8-20 nm. In vitro study of gallium nanoparticles on MCF-7 revealed IC50 of 8.0 MUg. Gallium nanoparticles (0.1 mg/kg body weight) were injected intraperitoneally daily on the seventh day of Ehrlich carcinoma cells inoculation. Whole-body gamma-radiation was carried out at a single dose of 0.25 Gy on eighth day after tumor inoculation. Biochemical analysis showed that solid Ehrlich carcinoma induced a significant increase in alanine aminotransferase activity and creatinine level in serum, calcium, and iron concentrations in liver tissue compared to normal control. Treatment of Ehrlich carcinoma-bearing mice with gallium nanoparticles and/or low dose of gamma radiation exposure significantly reduced tumor volume, decreased alanine aminotransferase and creatinine levels in serum, increased lipid peroxidation, and decreased glutathione content as well as calcium and iron concentrations in liver and tumor tissues with intense DNA fragmentation accompanied compared to untreated tumor cells. Moreover, mitochondria in the treated groups displayed a significant increase in Na+/K+-ATPase, complexes II and III with significant reduction in CYP450 gene expression, which may indicate a synergistic effect of gallium nanoparticles and/or low dose of gamma-radiation combination against Ehrlich carcinoma injury, and this results were well appreciated with the histopathological findings in the tumor tissue. We conclude that combined treatment of gallium nanoparticles and low dose of gamma-radiation resulted in suppressive induction of cytotoxic effects on cancer cells. PMID- 29587601 TI - Experimental evidence that preaxial polydactyly and forearm radial deficiencies may share a common developmental origin. AB - Preaxial polydactyly is a congenital hand anomaly predominantly of sporadic occurrence, which is frequently associated with abnormalities of the Sonic hedgehog signalling pathway. In experimentally induced preaxial polydactyly, radial aplasia is also frequently observed. To determine if there is a correlation between preaxial polydactyly and radial aplasia, we induced ectopic Sonic hedgehog signalling during chicken limb development with application of a smoothened-agonist (SAG) or retinoic acid. Application of SAG caused malformations in 71% limbs including preaxial polydactyly (62%) and forearm abnormalities (43%). Retinoic acid application induced malformations in 56% of limb including preaxial polydactyly (45%) and forearm abnormalities (50%). Radial dysplasia and ulnar dimelia were observed in both experimental conditions. We demonstrate that ectopic Sonic hedgehog signalling may cause both preaxial polydactyly and predictable forearm anomalies and that these conditions could potentially be classified as one embryological group. We propose a unifying model based on known models of ectopic Sonic hedgehog signalling. PMID- 29587602 TI - Kingella kingae hand and wrist tenosynovitis in young children. PMID- 29587603 TI - Fractures at the junction of diaphysis and metaphysis of the proximal phalanges in adults. AB - : We describe the treatment of 101 patients with 113 fractures of the proximal phalanx at the junction of the diaphysis with the proximal metaphysis. Fractures were stabilized using a single extra-articular percutaneous Kirschner wire passed lateral to the metacarpal head into the base of the phalanx base and across the fracture to engage the lateral cortex. Patients were treated semi-electively on a day surgery unit. The metacarpophalangeal joint was splinted in flexion with mobilization of the proximal inter-phalangeal joints, until the wire was removed at 24 days and the hand then freely mobilized. The mean total active movement was 230 degrees and no patients experienced problems with significant pain. There were two pin site infections. There were no cases of angular or rotational malunion. These injuries can be successfully and safely treated using this simple technique, negating the need for close monitoring for angular displacement of the fracture, which is frequently seen with non-surgical management. LEVEL OF EVIDENCE: IV. PMID- 29587604 TI - Effect of immobilization of the distal interphalangeal joint of fingers on grip strength. AB - Arthrodesis of the distal interphalangeal joint of the finger is an effective salvage treatment for end-stage arthropathy of the joint. This study aimed to evaluate the effect of simulated fusion of individual distal interphalangeal joints on the overall grip strength of the hand. Custom moulded thermoplastic splints were used to simulate fusion by immobilizing the index, middle, ring and little fingers' distal interphalangeal joints in turn in both hands of 56 healthy participants. Testing was performed with no immobilization and after immobilization of each of the individual digits. Grip strengths reduced significantly following immobilization of the distal interphalangeal joint. The degree of reduction became progressively more pronounced from the index to the little fingers (12%, 18%, 24% and 25%, respectively) and was similar for the dominant and non-dominant hands. This information may have clinical application when counselling patients regarding fusion of the distal interphalangeal joint of the fingers. PMID- 29587605 TI - Chondritis of the ear after docetaxel-carboplatin chemotherapy. AB - Docetaxel, derived from the yew tree, belongs to the taxane family of medications. It works by disrupting the normal function of microtubules, thereby stopping cell division. Docetaxel is used in the treatment of ovarian, breast, esophageal, gastric, prostate, lung, and head and neck cancers. Common side effects include hair loss, low blood cell counts, peripheral neuropathy, vomiting, and muscle pain. Auricular chondritis with ear deformity has not been reported previously as a side effect of docetaxel. In this paper, we present the case of a 64-year-old male patient with chondritis accompanied by ear deformity that developed due to docetaxel-carboplatin chemotherapy for non-small cell lung cancer.

PMID- 29587607 TI - Assessment of bleeding incidences associated with rivaroxaban therapy in adults with solid tumors. AB - PURPOSE: Report bleeding incidences associated with rivaroxaban in adult patients with solid tumor malignancies requiring anticoagulation therapy. METHODS: This retrospective review was conducted at Indiana University Health, University Hospital and the Simon Cancer Center in Indianapolis, IN from January 2013 - February 2016. Patients were included if they had a solid tumor malignancy and prescribed rivaroxaban. Data were collected on 144 patients. Major bleeding was defined as bleeding requiring treatment (local, systemic treatment, blood cell transfusions) or hospitalization and minor bleeding was defined as bleeding not requiring treatment or hospitalization. RESULTS: Sixty-four (44%) patients experienced bleeding while on rivaroxaban. There were six cancer types that had a higher incidence of bleeding: bladder, breast, melanoma, pancreas, prostate, and renal cell cancers; 40% (6/15) of patients with bladder cancer experienced bleeding; 54% (7/13) with breast cancer experienced bleeding; 40% (4/10) of patients with melanoma experienced bleeding; 58% (11/19) of patients with pancreatic cancer experienced bleeding; 45% (10/22) of patients with prostate cancer experienced bleeding; and 56% (5/9) of patients with renal cell carcinoma experienced bleeding. No other data collected identified increased incidence of bleeding. CONCLUSIONS: Patients on rivaroxaban with a diagnosis of bladder, breast, melanoma, pancreas, prostate, or renal cell cancers had a higher incidence of bleeding compared to other solid tumors. Major bleeding was higher in bladder, breast, pancreas, and renal cell carcinomas, while minor bleeding was higher in patients with melanoma and prostate cancer. PMID- 29587608 TI - A pilot study to assess the pharmacy impact of implementing a chemotherapy induced nausea or vomiting collaborative disease therapy management in the outpatient oncology clinics. AB - Background Collaborative drug therapy management is a formal partnership between a pharmacist and physician to allow the pharmacist to manage a patient's drug therapy. Literature supports collaborative disease therapy management can improve patient outcomes, improve medication adherence, enhance medication safety, and positively influence healthcare expenditures. Chemotherapy induced nausea or vomiting is considered one of the most distressing and feared adverse events among patients receiving chemotherapy. Chemotherapy induced nausea or vomiting can impact a patient's quality of life and may affect compliance with the treatment plan. Purpose The objective of this pilot study was to determine the pharmacy impact of implementing a chemotherapy induced nausea or vomiting collaborative disease therapy management protocol in the outpatient oncology clinics at a National Cancer Institute (NCI)-designated cancer center associated with an academic medical center. The primary endpoint was to determine the number and type of chemotherapy induced nausea or vomiting clinical interventions made by the oncology pharmacists. Secondary endpoints included comparing patient's Multinational Association for Supportive Care in Cancer scores and revenue of pharmacists' services. Methods The credentialed oncology pharmacists were consulted by an oncologist to manage chemotherapy induced nausea or vomiting. Patients were included in the chemotherapy induced nausea or vomiting collaborative disease therapy management if they were seen in an outpatient oncology clinic from October 2016 to January 2017 and had a referral from a qualified provider to help manage chemotherapy induced nausea or vomiting. Patients admitted to the hospital at the time of consult were excluded from the study. The pharmacists interviewed patients and provided recommendations. The pharmacists followed up with the patient via a telephone call or during the next scheduled clinic visit to assess their symptoms. Results The chemotherapy induced nausea or vomiting collaborative disease therapy management pilot study was implemented in October 2016. From October 2016 to January 2017, there were 45 consults for the management of chemotherapy induced nausea or vomiting. The pharmacists made 188 clinical interventions, which included addition of new medications (37%), patient education (34%), deletion of medications (10%), changing a dose/duration/frequency (8%), and other interventions (11%). Multinational Association for Supportive Care in Cancer symptom scores were available for 5 patients, in which all showed improvements from baseline with the pharmacists' clinical interventions. Conclusions The implementation of our chemotherapy induced nausea or vomiting collaborative disease therapy management pilot study has shown favorable results after a 4-month evaluation period. The pharmacists have made a substantial number of clinical interventions and provided patient education to patients undergoing chemotherapy.

AB - Our objective in this work was to isolate, identify, and compare micro-RNAs (miRNAs) found in spent culture media of euploid and aneuploid in vitro fertilization (IVF) embryos. Seventy-two embryos from 62 patients were collected, and their spent media were retained. A total of 108 spent conditioned media samples were analyzed (n = 36 day 3 euploid embryos, n = 36 day 3 aneuploid embryos, and n = 36 matched control media). Fifty hed-control media embryos were analyzed using next-generation sequencing (NGS) technology. We detected 53 known human miRNAs present in the spent conditioned media of euploid and aneuploid IVF embryos. miR-181b-5p and miR-191-5p were found the most represented. We validated our results by quantitative polymerase chain reaction (qPCR), but no significant results were obtained between the groups. In conclusion, we obtained the list of miRNAs present in the spent conditioned media from euploid and aneuploid IVF embryos, but our data suggest that these miRNAs could have a nonembryonic origin. PMID- 29587611 TI - Serum MicroRNA Biomarkers Regulated by Simvastatin in a Primate Model of Endometriosis. AB - Endometriosis is a chronic inflammatory and estrogen-dependent disease that causes pain and infertility in reproductive-aged women. Due to the delay in diagnosis, there is a pressing need for accurate biomarkers. Detection of serum noncoding RNA molecules such as microRNAs (miRNAs) shows promise as a noninvasive diagnostic strategy; we previously identified miRNAs that are highly sensitive and specific biomarkers for the disease. In this study, we investigate the expression of these miRNAs in a nonhuman primate model of endometriosis. As part of a pilot study evaluating simvastatin for the treatment of endometriosis, the disease was induced in 16 baboons by induction laparoscopy and the animals were divided into 2 groups. One group was treated with simvastatin for 90 days, while the second group received vehicle only. Endometriosis was evaluated after 3 months by laparoscopy. Serum samples were analyzed for 9 circulating miRNAs using quantitative real time-polymerase chain reaction, focusing on the miRNAs we found to be dysregulated in human endometriosis. In the simvastatin-treated endometriosis group, levels of miR-150-5p and miR-451a were decreased, while miR 3613-5p levels were increased compared to the untreated endometriosis group. The changes in circulating miRNA expression patterns parallel our previous results in human patients and show that specific miRNAs correlate with endometriosis severity and reverted toward control expression levels after simvastatin treatment. This is the first report showing serum miRNA expression normalized in response to endometriosis treatment, supporting the potential for this class of biomarkers to be used both to diagnose endometriosis and to monitor its progression and response to therapy. PMID- 29587612 TI - Regulatory Functions of MicroRNAs in Male Reproductive Health: A New Approach to Understanding Male Infertility. AB - MicroRNAs (miRNAs) are a novel class of small noncoding RNAs (ncRNAs) that play critical roles in regulation of gene expression, especially at posttranscriptional level. Over the past decade, the degree to which miRNAs are involved in male infertility has become clear. They are expressed in a cell- or phase-specific manner during spermatogenesis and play crucial role in male reproductive health. Therefore, dysregulation of miRNAs in testicular cells can be considered as a molecular basis for reproductive failure and male infertility. The abnormal expression pattern of miRNAs can be transmitted to the offspring via assisted reproductive techniques (ART) and results in the birth of children with a higher risk of infertility, congenital abnormalities, and morbidity. This review expounds on the miRNAs reported to play essential roles in somatic cells development, germ cells differentiation, steroidogenesis, normal spermatogenesis, sperm maturation, and male infertility, as well as emphasizes their importance as minimally invasive biomarkers of male infertility.

AB - Pharmacogenomics is a promising approach in the field of individualized medicine in in vitro fertilization (IVF) treatment that aims to develop optimized pharmacotherapy depending on the genetic background of each infertile woman, thus to ensure maximum effectiveness of the medication used, with minimal side effects. The unique genetic information of each infertile woman, in combination with already known, as well as new predictors of ovarian response and the progress of pharmacoepigenomics, is anticipated to greatly benefit the process of controlled ovarian stimulation. This review analyses current data on IVF pharmacogenomics, a new approach that is gradually moving to the frontline of modern IVF treatment. PMID- 29587613 TI - G-Protein-Coupled Receptor CXCR7 Is Overexpressed in Human and Murine Endometriosis. AB - Endometriosis is a chronic inflammatory disease. Dysfunctional regulation of chemokines and chemokine receptors is a crucial aspect of endometriosis pathogenesis. Chemokine G-protein-coupled receptors (GPCRs) are important drug targets that regulate inflammation and immunity. Recently, CXCR7, a C-X-C motif containing GPCR, has been identified as a receptor for chemokine ligand CXCL12, one of the best characterized chemokines for cell trafficking, angiogenesis, and cell proliferation in cancer and inflammation. Here, we investigated the expression and localization of CXCR7 in human endometriosis and a murine model of the disease. Normal endometrial epithelium and stroma showed undetectable or very low expression of CXCR7, without any significant changes across phases of the menstrual cycle in humans. CXCR7 is significantly upregulated in endometriosis, showing higher staining in glands and in associated vessels. The mouse model recapitulated the human findings. In conclusion, overexpression of CXCR7 in different cellular populations of endometriosis microenvironment may play a role in the pathogenesis and represent a novel target for treatment. PMID- 29587615 TI - 25-Hydroxyvitamin D Serum Levels and Endometriosis: Results of a Case-Control Study. AB - The immunomodulatory, anti-inflammatory, and antiproliferative properties of vitamin D have laid the basis for a possible function of this prohormone in the pathogenesis of endometriosis. The aim of this case-control study was to investigate vitamin D status, by measuring 25-hydroxyvitamin D [25(OH)D] serum levels, in women with and without endometriosis. Only Italian women of Caucasian origin aged between 18 and 45 years were deemed eligible. Enrollment was limited to the period October to May. Cases and controls were matched for month of recruitment and secondarily for age and parity. Overall, 434 women were enrolled (endometriosis n = 217; controls n = 217). The group of cases included 127 women with ovarian endometrioma and 90 patients with deep endometriosis. Mean (standard deviation) levels of 25(OH)D in women with and without endometriosis were 17.9 (7.0) ng/mL and 18.4 (7.6) ng/mL, respectively ( P = .46). Analyzing the two endometriosis subgroups separately, no statistically significant differences emerged (18.7 [7.4] ng/mL in deep endometriosis group vs 17.3 [6.6] ng/mL in women with ovarian endometrioma; P = .14). Comparing the subgroup of women with deep endometriosis with paired controls, no differences occurred (18.7 [7.4] ng/mL vs 18.5 [7.7] ng/mL, P = .80). Similar data emerged when performing the same analysis for ovarian endometriomas (17.4 [6.6] ng/mL vs 18.3 [7.6] ng/mL, P = .23). The results of the present case-control study do not support an association between serum vitamin D levels and different phenotypes of endometriosis. PMID- 29587616 TI - Molecular Mechanisms of Prophase I Meiotic Arrest Maintenance and Meiotic Resumption in Mammalian Oocytes. AB - Mechanisms of meiotic prophase I arrest maintenance (germinal vesicle [GV] stage) and meiotic resumption (germinal vesicle breakdown [GVBD] stage) in mammalian oocytes seem to be very complicated. These processes are regulated via multiple molecular cascades at transcriptional, translational, and posttranslational levels, and many of them are interrelated. There are many molecular cascades of meiosis maintaining and meiotic resumption in oocyte which are orchestrated by multiple molecules produced by pituitary gland and follicular cells. Furthermore, many of these molecular cascades are duplicated, thus ensuring the stability of the entire system. Understanding mechanisms of oocyte maturation is essential to assess the oocyte status, develop effective protocols of oocyte in vitro maturation, and design novel contraceptive drugs. Mechanisms of meiotic arrest maintenance at prophase I and meiotic resumption in mammalian oocytes are covered in the present article. PMID- 29587617 TI - Retinoic Acid Pathway Regulation of Vascular Endothelial Growth Factor in Ovine Amnion. AB - Vascular endothelial growth factor (VEGF) has been proposed as an important regulator of amniotic fluid absorption across the amnion into the fetal vasculature on the surface of the placenta. However, the activators of VEGF expression and action in the amnion have not been identified. Using the pregnant sheep model, we aimed to investigate the presence of the retinoic acid (RA) pathway in ovine amnion and to determine its effect on VEGF expression. Further, we explored relationships between RA receptors and VEGF and tested the hypothesis that RA modulates intramembranous absorption (IMA) through induction of amnion VEGF in sheep fetuses subjected to altered IMA rates. Our study showed that RA receptor isoforms were expressed in sheep amnion, and RA response elements (RAREs) were identified in ovine RARbeta and VEGF gene promoters. In ovine amnion cells, RA treatment upregulated RARbeta messenger RNA (mRNA) and increased VEGF transcript levels. In sheep fetuses, increases in IMA rate was associated with elevated VEGF mRNA levels in the amnion but not in the chorion. Further, RARbeta mRNA was positively correlated with VEGF mRNA levels in the amnion and not chorion. We conclude that an RA pathway is present in ovine fetal membranes and that RA is capable of inducing VEGF. The finding of a positive relationship between amnion VEGF and RARbeta during altered IMA rate suggests that the retinoid pathway may play a role through VEGF in regulating intramembranous transport across the amnion.

The first approach employed an oxidative cleavage of an alpha-hydroxy ketone intermediate with the Jones reagent as the key step to reach the targeted secoergostane from ergosterol in ten steps. In the second approach, an unprecedented reaction cascade composed of four reactions enabled us to obtain the secoergostane more efficiently in six steps.

AB - Diacylglycerol acyltransferase 1 (DGAT1) catalyzes the final step in triglyceride synthesis. Since Dgat1-/- mice fed a high-fat diet (HFD) are resistant to hepatic steatosis, DGAT1 inhibitors are expected to have antifatty liver effects. To evaluate the hepatic effects of DS-7250, a selective DGAT1 inhibitor, vehicle or 10 mg/kg of DS-7250 was administered orally to male Fisher 344 (F344) and Zucker fatty (ZF) rats fed a standard diet or HFD for 14 or 28 days. ZF rats showed slight hepatic steatosis regardless of feeding conditions. DS-7250 exacerbated hepatic steatosis in ZF rats fed an HFD compared with the vehicle control. Hepatic steatosis did not occur in F344 rats fed an HFD, in which systemic exposures of DS-7250 were comparable to those in ZF rats. There was a higher expression of genes involved in lipid uptake and fatty acid synthesis in ZF rats compared to F344 rats under HFD conditions. DS-7250 upregulated key genes involved in de novo lipogenesis, which causes hepatic steatosis independently of DGAT1, in ZF rats fed an HFD compared with the vehicle control. These data suggest that ZF rats were more susceptible to hepatic steatosis due to their genetic characteristics and DS-7250 exacerbated hepatic steatosis independently of DGAT1.

AB - The chondroprotective effect of olive leaf extract (OLE) on knee osteoarthritis (OA) was studied with STR/ort mice (n = 5). OLE was administrated with a dosage of 100 mg/kg for 8 weeks and the OA severity score of hind limb knee joints was then measured. The Mankin scores of the knee joints of the non-OA control group, OA control group and OLE-treated group were 3.50, 11.13 and 7.20, respectively. This suggests that oral OLE supplements help prevent cartilage degeneration in STR/ort mice. In vitro, the synthesis of high molecular weight hyaluronan in synovial cells (HIG-82) was increased by OLE stimulation. This suggests that OLE modulates hyaluronan metabolism in synovial cells and improves OA symptoms. Our findings indicate that OLE intake inhibits cartilage destruction by increasing high molecular weight hyaluronan and thus preventing OA progress. PMID- 29587624 TI - Diabetes classification model based on boosting algorithms. AB - BACKGROUND: Diabetes mellitus is a common and complicated chronic lifelong disease. Hence, it is of high clinical significance to find the most relevant clinical indexes and to perform efficient computer-aided pre-diagnoses and diagnoses. RESULTS: Non-parametric statistical testing is performed on hundreds of medical measurement index results between diabetic and non-diabetic populations. Two common boosting algorithms, Adaboost.M1 and LogitBoost, are selected to establish a machine model for diabetes diagnosis based on these clinical test data, involving a total of 35,669 individuals. The machine classification models built by these two algorithms have very good classification ability. Here, the LogitBoost classification model is slightly better than the Adaboost.M1 classification model. The overall accuracy of the LogitBoost classification model reached 95.30% when using 10-fold cross validation. The true positive, true negative, false positive, and false negative rates of the binary classification model were 0.921, 0.969, 0.031, and 0.079, respectively, and the area under the receiver operating characteristic curve reached 0.99. CONCLUSIONS: The boosting algorithms show excellent performance for the diabetes classification models based on clinical medical data. The coefficient matrix of the original data is a sparse matrix, because some of the test results were missing, including some that were directly related to disease diagnosis. Therefore, the model is robust and has a degree of pre-diagnosis function. In the process of selecting the preferred test items, the most statistically significant discriminating factors between the diabetic and general populations were obtained and can be used as reference risk factors for diabetes mellitus. PMID- 29587625 TI - The effects of intranasal oxytocin on reward circuitry responses in children with autism spectrum disorder. AB - BACKGROUND: Intranasal oxytocin (OT) has been shown to improve social communication functioning of individuals with autism spectrum disorder (ASD) and, thus, has received considerable interest as a potential ASD therapeutic agent. Although preclinical research indicates that OT modulates the functional output of the mesocorticolimbic dopamine system that processes rewards, no clinical brain imaging study to date has examined the effects of OT on this system using a reward processing paradigm. To address this, we used an incentive delay task to examine the effects of a single dose of intranasal OT, versus placebo (PLC), on neural responses to social and nonsocial rewards in children with ASD. METHODS: In this placebo-controlled double-blind study, 28 children and adolescents with ASD (age: M = 13.43 years, SD = 2.36) completed two fMRI scans, one after intranasal OT administration and one after PLC administration. During both scanning sessions, participants completed social and nonsocial incentive delay tasks. Task-based neural activation and connectivity were examined to assess the impact of OT relative to PLC on mesocorticolimbic brain responses to social and nonsocial reward anticipation and outcomes. RESULTS: Central analyses compared the OT and PLC conditions. During nonsocial reward anticipation, there was greater activation in the right nucleus accumbens (NAcc), left anterior cingulate cortex (ACC), bilateral orbital frontal cortex (OFC), left superior frontal cortex, and right frontal pole (FP) during the OT condition relative to PLC. Alternatively, during social reward anticipation and outcomes, there were no significant increases in brain activation during the OT condition relative to PLC. A Treatment Group * Reward Condition interaction revealed relatively greater activation in the right NAcc, right caudate nucleus, left ACC, and right OFC during nonsocial relative to social reward anticipation during the OT condition relative to PLC. Additionally, these analyses revealed greater activation during nonsocial reward outcomes during the OT condition relative to PLC in the right OFC and left FP. Finally, functional connectivity analyses generally revealed changes in frontostriatal connections during the OT condition relative to PLC in response to nonsocial, but not social, rewards. CONCLUSIONS: The effects of intranasal OT administration on mesocorticolimbic brain systems that process rewards in ASD were observable primarily during the processing of nonsocial incentive salience stimuli. These findings have implications for understanding the effects of OT on neural systems that process rewards, as well as for experimental trials of novel ASD treatments developed to ameliorate social communication impairments in ASD. PMID- 29587627 TI - Obtaining insights from high-dimensional data: sparse principal covariates regression. AB - BACKGROUND: Data analysis methods are usually subdivided in two distinct classes: There are methods for prediction and there are methods for exploration. In practice, however, there often is a need to learn from the data in both ways. For example, when predicting the antibody titers a few weeks after vaccination on the basis of genomewide mRNA transcription rates, also mechanistic insights about the effect of vaccinations on the immune system are sought. Principal covariates regression (PCovR) is a method that combines both purposes. Yet, it misses insightful representations of the data as these include all the variables. RESULTS: Here, we propose a sparse extension of principal covariates regression such that the resulting solutions are based on an automatically selected subset of the variables. Our method is shown to outperform competing methods like sparse principal components regression and sparse partial least squares in a simulation study. Furthermore good performance of the method is illustrated on publicly available data including antibody titers and genomewide transcription rates for subjects vaccinated against the flu: the selected genes by sparse PCovR are higly enriched for immune related terms and the method predicts the titers for an independent test sample well. In comparison, no significantly enriched terms were found for the genes selected by sparse partial least squares and out-of-sample prediction was worse. CONCLUSIONS: Sparse principal covariates regression is a promising and competitive tool for obtaining insights from high-dimensional data.

PMID- 29587626 TI - Diversity and distribution of Wolbachia in relation to geography, host plant affiliation and life cycle of a heterogonic gall wasp. AB - BACKGROUND: The maternally inherited endosymbiont Wolbachia is widespread in arthropods and nematodes and can play an important role in the ecology and evolution of its host through reproductive manipulation. Here, we survey Wolbachia in Belonocnema treatae, a widely distributed North American cynipid gall forming wasp that exhibits regional host specialization on three species of oaks and alternation of sexually and asexually reproducing generations. We investigated whether patterns of Wolbachia infection and diversity in B. treatae are associated with the insect's geographic distribution, host plant association, life cycle, and mitochondrial evolutionary history. RESULTS: Screening of 463 individuals from 23 populations including sexual and asexual generations from all three host plants across the southern U.S. showed an average infection rate of 56% with three common Wolbachia strains: wTre1-3 and an additional rare variant wTre4. Phylogenetic analysis based on wsp showed that these strains are unrelated and likely independently inherited. We found no difference in Wolbachia infection frequency among host plant associated populations or between the asexual and sexual generations, or between males and females of the sexual generation. Partially incomplete Wolbachia transmission rates might explain the occurrence of uninfected individuals. A parallel analysis of the mitochondrial cytochrome oxidase I gene in B. treatae showed high mtDNA haplotype diversity in both infected and uninfected populations suggesting an ancestral infection by Wolbachia as well as a clear split between eastern and western B. treatae mtDNA clades with a sequence divergence of > 6%. The strain wTre1 was present almost exclusively in the western clade while wTre2 and wTre3 occur almost exclusively in eastern populations. In contrast, the same strains co-occur as double infections in Georgia and triple-infections in two populations in central Florida. CONCLUSIONS: The diversity of Wolbachia across geographically and genetically distinct populations of B. treatae and the co-occurrence of the same strains within three populations highlights the complex infection dynamics in this system. Moreover, the association of distinct Wolbachia strains with mitochondrial haplotypes of its host in populations infected by different Wolbachia strains suggests a potential role of the endosymbiont in reproductive isolation in B. treatae. PMID- 29587628 TI - A method combining a random forest-based technique with the modeling of linkage disequilibrium through latent variables, to run multilocus genome-wide association studies. AB - BACKGROUND: Genome-wide association studies (GWASs) have been widely used to discover the genetic basis of complex phenotypes. However, standard single-SNP GWASs suffer from lack of power. In particular, they do not directly account for linkage disequilibrium, that is the dependences between SNPs (Single Nucleotide Polymorphisms). RESULTS: We present the comparative study of two multilocus GWAS strategies, in the random forest-based framework. The first method, T-Trees, was designed by Botta and collaborators (Botta et al., PLoS ONE 9(4):e93379, 2014). We designed the other method, which is an innovative hybrid method combining T Trees with the modeling of linkage disequilibrium. Linkage disequilibrium is modeled through a collection of tree-shaped Bayesian networks with latent variables, following our former works (Mourad et al., BMC Bioinformatics 12(1):16, 2011). We compared the two methods, both on simulated and real data. For dominant and additive genetic models, in either of the conditions simulated, the hybrid approach always slightly performs better than T-Trees. We assessed predictive powers through the standard ROC technique on 14 real datasets. For 10 of the 14 datasets analyzed, the already high predicted power observed for T Trees (0.910-0.946) can still be increased by up to 0.030. We also assessed whether the distributions of SNPs' scores obtained from T-Trees and the hybrid approach differed. Finally, we thoroughly analyzed the intersections of top 100 SNPs output by any two or the three methods amongst T-Trees, the hybrid approach, and the single-SNP method. CONCLUSIONS: The sophistication of T-Trees through finer linkage disequilibrium modeling is shown beneficial. The distributions of SNPs' scores generated by T-Trees and the hybrid approach are shown statistically different, which suggests complementary of the methods. In particular, for 12 of the 14 real datasets, the distribution tail of highest SNPs' scores shows larger values for the hybrid approach. Thus are pinpointed more interesting SNPs than by T-Trees, to be provided as a short list of prioritized SNPs, for a further analysis by biologists. Finally, among the 211 top 100 SNPs jointly detected by the single-SNP method, T-Trees and the hybrid approach over the 14 datasets, we identified 72 and 38 SNPs respectively present in the top25s and top10s for each method. PMID- 29587629 TI - Comparative analysis of FKBP family protein: evaluation, structure, and function in mammals and Drosophila melanogaster. AB - BACKGROUND: FK506-binding proteins (FKBPs) have become the subject of considerable interest in several fields, leading to the identification of several cellular and molecular pathways in which FKBPs impact prenatal development and pathogenesis of many human diseases. MAIN BODY: This analysis revealed differences between how mammalian and Drosophila FKBPs mechanisms function in relation to the immunosuppressant drugs, FK506 and rapamycin. Differences that could be used to design insect-specific pesticides. (1) Molecular phylogenetic analysis of FKBP family proteins revealed that the eight known Drosophila FKBPs share homology with the human FKBP12. This indicates a close evolutionary relationship, and possible origination from a common ancestor. (2) The known FKBPs contain FK domains, that is, a prolyl cis/trans isomerase (PPIase) domain that mediates immune suppression through inhibition of calcineurin. The dFKBP59, CG4735/Shutdown, CG1847, and CG5482 have a Tetratricopeptide receptor domain at the C-terminus, which regulates transcription and protein transportation. (3) FKBP51 and FKBP52 (dFKBP59), along with Cyclophilin 40 and protein phosphatase 5, function as Hsp90 immunophilin co-chaperones within steroid receptor-Hsp90 heterocomplexes. These immunophilins are potential drug targets in pathways associated with normal physiology and may be used to treat a variety of steroid based diseases by targeting exocytic/endocytic cycling and vesicular trafficking. (4) By associating with presinilin, a critical component of the Notch signaling pathway, FKBP14 is a downstream effector of Notch activation at the membrane. Meanwhile, Shutdown associates with transposons in the PIWI-interacting RNA pathway, playing a crucial role in both germ cells and ovarian somas. Mutations in or silencing of dFKBPs lead to early embryonic lethality in Drosophila. Therefore, further understanding the mechanisms of FK506 and rapamycin binding to immunophilin FKBPs in endocrine, cardiovascular, and neurological function in both mammals and Drosophila would provide prospects in generating unique, insect specific therapeutics targeting the above cellular signaling pathways. CONCLUSION: This review will evaluate the functional roles of FKBP family proteins, and systematically summarize the similarities and differences between FKBP proteins in Drosophila and Mammals. Specific therapeutics targeting cellular signaling pathways will also be discussed. PMID- 29587630 TI - Notos - a galaxy tool to analyze CpN observed expected ratios for inferring DNA methylation types. AB - BACKGROUND: DNA methylation patterns store epigenetic information in the vast majority of eukaryotic species. The relatively high costs and technical challenges associated with the detection of DNA methylation however have created a bias in the number of methylation studies towards model organisms. Consequently, it remains challenging to infer kingdom-wide general rules about the functions and evolutionary conservation of DNA methylation. Methylated cytosine is often found in specific CpN dinucleotides, and the frequency distributions of, for instance, CpG observed/expected (CpG o/e) ratios have been used to infer DNA methylation types based on higher mutability of methylated CpG. RESULTS: Predominantly model-based approaches essentially founded on mixtures of Gaussian distributions are currently used to investigate questions related to the number and position of modes of CpG o/e ratios. These approaches require the selection of an appropriate criterion for determining the best model and will fail if empirical distributions are complex or even merely moderately skewed. We use a kernel density estimation (KDE) based technique for robust and precise characterization of complex CpN o/e distributions without a priori assumptions about the underlying distributions. CONCLUSIONS: We show that KDE delivers robust descriptions of CpN o/e distributions. For straightforward processing, we have developed a Galaxy tool, called Notos and available at the ToolShed, that calculates these ratios of input FASTA files and fits a density to their empirical distribution. Based on the estimated density the number and shape of modes of the distribution is determined, providing a rational for the prediction of the number and the types of different methylation classes. Notos is written in R and Perl. PMID- 29587631 TI - Integrative analysis reveals ncRNA-mediated molecular regulatory network driving secondary hair follicle regression in cashmere goats. AB - BACKGROUND: Cashmere is a keratinized product derived from the secondary hair follicles (SHFs) of cashmere goat skins. The cashmere fiber stops growing following the transition from the actively proliferating anagen stage to the apoptosis-driven catagen stage. However, little is known regarding the molecular mechanisms responsible for the occurrence of apoptosis in SHFs, especially as pertains to the role of non-coding RNAs (ncRNAs) and their interactions with other molecules. Hair follicle (HF) degeneration is caused by localized apoptosis in the skin, while anti-apoptosis pathways may coexist in adjacent HFs. Thus, elucidating the molecular interactions responsible for apoptosis and anti apoptosis in the skin will provide insights into HF regression. RESULTS: We used multiple-omics approaches to systematically identify long non-coding RNAs (lncRNAs), microRNAs (miRNAs) and mRNAs expressed in cashmere goat skins in two crucial phases (catagen vs. anagen) of HF growth. Skin samples were collected from three cashmere goats at the anagen (September) and catagen (February) stages, and six lncRNA libraries and six miRNA libraries were constructed for further analysis. We identified 1122 known and 403 novel lncRNAs in the goat skins, 173 of which were differentially expressed between the anagen and catagen stages. We further identified 3500 gene-encoding transcripts that were differentially expressed between these two phases. We also identified 411 known miRNAs and 307 novel miRNAs, including 72 differentially expressed miRNAs. We further investigated the target genes of lncRNAs via both cis- and trans regulation during HF growth. Our data suggest that lncRNAs and miRNAs act synergistically in the HF growth transition, and the catagen inducer factors (TGFbeta1 and BDNF) were regulated by miR-873 and lnc108635596 in the lncRNA miRNA-mRNA networks. CONCLUSION: This study enriches the repertoire of ncRNAs in goats and other mammals, and contributes to a better understanding of the molecular mechanisms of ncRNAs involved in the regulation of HF growth and regression in goats and other hair-producing species. PMID- 29587632 TI - Transcriptomic profiling of tall fescue in response to heat stress and improved thermotolerance by melatonin and 24-epibrassinolide. AB - BACKGROUND: Tall fescue is a widely used cool season turfgrass and relatively sensitive to high temperature. Chemical compounds like melatonin (MT) and 24 epibrassinolide (EBL) have been reported to improve plant heat stress tolerance effectively. RESULTS: In this study, we reported that MT and EBL pretreated tall fescue seedlings showed decreased reactive oxygen species (ROS), electrolyte leakage (EL) and malondialdehide (MDA), but increased chlorophyll (Chl), total protein and antioxidant enzyme activities under heat stress condition, resulting in improved plant growth. Transcriptomic profiling analysis showed that 4311 and 8395 unigenes were significantly changed after 2 h and 12 h of heat treatments, respectively. Among them, genes involved in heat stress responses, DNA, RNA and protein degradation, redox, energy metabolisms, and hormone metabolism pathways were highly induced after heat stress. Genes including FaHSFA3, FaAWPM and FaCYTC2 were significantly upregulated by both MT and EBL treatments, indicating that these genes might function as the putative target genes of MT and EBL. CONCLUSIONS: These findings indicated that heat stress caused extensively transcriptomic reprogramming of tall fescue and exogenous application of MT and EBL effectively improved thermotolerance in tall fescue. PMID- 29587633 TI - The complete mitochondrial genome of the hermaphroditic freshwater mussel Anodonta cygnea (Bivalvia: Unionidae): in silico analyses of sex-specific ORFs across order Unionoida. AB - BACKGROUND: Doubly uniparental inheritance (DUI) of mitochondrial DNA in bivalves is a fascinating exception to strictly maternal inheritance as practiced by all other animals. Recent work on DUI suggests that there may be unique regions of the mitochondrial genomes that play a role in sex determination and/or sexual development in freshwater mussels (order Unionoida). In this study, one complete mitochondrial genome of the hermaphroditic swan mussel, Anodonta cygnea, is sequenced and compared to the complete mitochondrial genome of the gonochoric duck mussel, Anodonta anatina. An in silico assessment of novel proteins found within freshwater bivalve species (known as F-, H-, and M-open reading frames or ORFs) is conducted, with special attention to putative transmembrane domains (TMs), signal peptides (SPs), signal cleavage sites (SCS), subcellular localization, and potential control regions. Characteristics of TMs are also examined across freshwater mussel lineages. RESULTS: In silico analyses suggests the presence of SPs and SCSs and provides some insight into possible function(s) of these novel ORFs. The assessed confidence in these structures and functions was highly variable, possibly due to the novelty of these proteins. The number and topology of putative TMs appear to be maintained among both F- and H-ORFs, however, this is not the case for M-ORFs. There does not appear to be a typical control region in H-type mitochondrial DNA, especially given the loss of tandem repeats in unassigned regions when compared to F-type mtDNA. CONCLUSION: In silico analyses provides a useful tool to discover patterns in DUI and to navigate further in situ analyses related to DUI in freshwater mussels. In situ analysis will be necessary to further explore the intracellular localizations and possible role of these open reading frames in the process of sex determination in freshwater mussel. PMID- 29587634 TI - High-throughput detection of RNA processing in bacteria. AB - BACKGROUND: Understanding the RNA processing of an organism's transcriptome is an essential but challenging step in understanding its biology. Here we investigate with unprecedented detail the transcriptome of Pseudomonas aeruginosa PAO1, a medically important and innately multi-drug resistant bacterium. We systematically mapped RNA cleavage and dephosphorylation sites that result in 5' monophosphate terminated RNA (pRNA) using monophosphate RNA-Seq (pRNA-Seq). Transcriptional start sites (TSS) were also mapped using differential RNA-Seq (dRNA-Seq) and both datasets were compared to conventional RNA-Seq performed in a variety of growth conditions. RESULTS: The pRNA-Seq library revealed known tRNA, rRNA and transfer-messenger RNA (tmRNA) processing sites, together with previously uncharacterized RNA cleavage events that were found disproportionately near the 5' ends of transcripts associated with basic bacterial functions such as oxidative phosphorylation and purine metabolism. The majority (97%) of the processed mRNAs were cleaved at precise codon positions within defined sequence motifs indicative of distinct endonucleolytic activities. The most abundant of these motifs corresponded closely to an E. coli RNase E site previously established in vitro. Using the dRNA-Seq library, we performed an operon analysis and predicted 3159 potential TSS. A correlation analysis uncovered 105 antiparallel pairs of TSS that were separated by 18 bp from each other and were centered on single palindromic TAT(A/T)ATA motifs (likely - 10 promoter elements), suggesting that, consistent with previous in vitro experimentation, these sites can initiate transcription bi-directionally and may thus provide a novel form of transcriptional regulation. TSS and RNA-Seq analysis allowed us to confirm expression of small non-coding RNAs (ncRNAs), many of which are differentially expressed in swarming and biofilm formation conditions. CONCLUSIONS: This study uses pRNA-Seq, a method that provides a genome-wide survey of RNA processing, to study the bacterium Pseudomonas aeruginosa and discover extensive transcript processing not previously appreciated. We have also gained novel insight into RNA maturation and turnover as well as a potential novel form of transcription regulation.

PMID- 29587635 TI - Genome-wide transcriptional analyses in Anopheles mosquitoes reveal an unexpected association between salivary gland gene expression and insecticide resistance. AB - BACKGROUND: To combat malaria transmission, the Ugandan government has embarked upon an ambitious programme of indoor residual spraying (IRS) with a carbamate class insecticide, bendiocarb. In preparation for this campaign, we characterized bendiocarb resistance and associated transcriptional variation among Anopheles gambiae s.s. mosquitoes from two sites in Uganda. RESULTS: Gene expression in two mosquito populations displaying some resistance to bendiocarb (95% and 79% An. gambiae s.l. WHO tube bioassay mortality in Nagongera and Kihihi, respectively) was investigated using whole-genome microarrays. Significant overexpression of several genes encoding salivary gland proteins, including D7r2 and D7r4, was detected in mosquitoes from Nagongera. In Kihihi, D7r4, two detoxification associated genes (Cyp6m2 and Gstd3) and an epithelial serine protease were among the genes most highly overexpressed in resistant mosquitoes. Following the first round of IRS in Nagongera, bendiocarb-resistant mosquitoes were collected, and real-time quantitative PCR analyses detected significant overexpression of D7r2 and D7r4 in resistant mosquitoes. A single nucleotide polymorphism located in a non-coding transcript downstream of the D7 genes was found at a significantly higher frequency in resistant individuals. In silico modelling of the interaction between D7r4 and bendiocarb demonstrated similarity between the insecticide and serotonin, a known ligand of D7 proteins. A meta-analysis of published microarray studies revealed a recurring association between D7 expression and insecticide resistance across Anopheles species and locations. CONCLUSIONS: A whole-genome microarray approach identified an association between novel insecticide resistance candidates and bendiocarb resistance in Uganda. In addition, a single nucleotide polymorphism associated with this resistance mechanism was discovered. The use of such impartial screening methods allows for discovery of resistance candidates that have no previously-ascribed function in insecticide binding or detoxification. Characterizing these novel candidates will broaden our understanding of resistance mechanisms and yield new strategies for combatting widespread insecticide resistance among malaria vectors. PMID- 29587636 TI - The attenuation of neurological injury from the use of simvastatin after spinal cord ischemia-reperfusion injury in rats. AB - BACKGROUND: Spinal cord ischemic injury remains a serious complication of open surgical and endovascular aortic procedures. Simvastatin has been reported to be associated with neuroprotective effect after spinal cord ischemia-reperfusion (IR) injury. The aim of this study was to determine the therapeutic efficacy of starting simvastatin after spinal cord IR injury in a rat model. METHODS: In adult Sprague-Dawley rats, spinal cord ischemia was induced using a balloon tipped catheter placed in the descending thoracic aorta. The animals were then randomly divided into 4 groups: group A (control); group B (0.5 mg/kg simvastatin); group C (1 mg/kg simvastatin); and group D (10 mg/kg simvastatin). Simvastatin was administered orally upon reperfusion for 5 days. Neurological function of the hind limbs was evaluated for 7 days after reperfusion and recorded using a motor deficit score (MDS) (0: normal, 5: complete paraplegia). The number of normal motor neurons within the anterior horns of the spinal cord was counted after final MDS evaluation. Then, the spinal cord was harvested for histopathological examination. RESULTS: Group D showed a significantly lower MDS than the other groups at post-reperfusion day 1 and this trend was sustained throughout the study period. Additionally, a greater number of normal motor neurons was observed in group D than in other groups (group D 21.2 [3.2] vs. group A: 15.8 [4.2]; group B 15.4 [3.4]; and group C 15.5 [3.7]; P = 0.002). CONCLUSIONS: The results of the current study suggest that 10 mg/kg can significantly improve neurologic outcome by attenuating neurologic injury and restoring normal motor neurons after spinal cord IR injury. PMID- 29587637 TI - Combining QTL-seq and linkage mapping to fine map a wild soybean allele characteristic of greater plant height. AB - BACKGROUND: Plant height (PH) is an important agronomic trait and is closely related to yield in soybean [Glycine max (L.) Merr.]. Previous studies have identified many QTLs for PH. Due to the complex genetic background of PH in soybean, there are few reports on its fine mapping. RESULTS: In this study, we used a mapping population derived from a cross between a chromosome segment substitution line CSSL3228 (donor N24852 (G. Soja), a receptor NN1138-2 (G. max)) and NN1138-2 to fine map a wild soybean allele of greater PH by QTL-seq and linkage mapping. We identified a QTL for PH in a 1.73 Mb region on soybean chromosome 13 through QTL-seq, which was confirmed by SSR marker-based classical QTL mapping in the mapping population. The linkage analysis showed that the QTLs of PH were located between the SSR markers BARCSOYSSR_13_1417 and BARCSOYSSR_13_1421 on chromosome 13, and the physical distance was 69.3 kb. RT PCR and sequence analysis of possible candidate genes showed that Glyma.13 g249400 revealed significantly higher expression in higher PH genotypes, and the gene existed 6 differences in the amino acids encoding between the two parents. CONCLUSIONS: Data presented here provide support for Glyma.13 g249400 as a possible candidate genes for higher PH in wild soybean line N24852. PMID- 29587638 TI - Cerebral microbleeds shouldn't dictate treatment of acute stroke: a retrospective cohort study evaluating risk of intracerebral hemorrhage. AB - BACKGROUND: Intravenous tissue plasminogen activator (IV tPA) after acute ischemic stroke carries the risk of symptomatic intracerebral hemorrhage (sICH). Cerebral microbleeds (CMBs) may indicate increased risk of hemorrhage and can be seen on magnetic resonance imaging (MRI). In this study, we examined the association between CMBs and sICH, focusing on the predictive value of their presence, burden, and location. METHODS: Records from all patients presenting to two academic stroke centers with acute ischemic stroke treated with IV tPA over a 5-year period were retrospectively reviewed. Demographic, medical, and imaging variables were evaluated. The presence, number, and location (lobar vs nonlobar) of CMBs were noted on gradient echo MRI sequences obtained during the admission. Univariable and multivariable statistical models were used to determine the relationship between CMBs and hemorrhagic (symptomatic and asymptomatic) transformation. RESULTS: Of 292 patients (mean age 62.8 years (SD 15.3), 49% African-American, 52% women), 21% (n = 62) had at least one CMB, 1% (n = 3) had > 10 CMBs, and 1% (n = 3) were diagnosed with probable cerebral amyloid angiopathy. After treatment, 16% (n = 46) developed hemorrhagic transformation, of which 6 (2%) were sICH. There was no association between CMB presence (p = .135) or location (p = .325) with sICH; however, those with a high CMB burden (> 10 CMB) were more likely to develop sICH (OR 37.8; 95% CI: 2.7-539.3; p = .007). CONCLUSIONS: Our findings support prior findings that a high CMB burden (> 10) in patients with acute stroke treated with IV tPA are associated with a higher risk of sICH. However, the overall rate of sICH in the presence of CMB is very low, indicating that the presence of CMBs by itself should not dictate the decision to treat with thrombolytics. PMID- 29587639 TI - MiR-146a G/C rs2910164 variation in South African Indian and Caucasian patients with psoriatic arthritis. AB - BACKGROUND: Psoriasis and psoriatic arthritis (PsA) are inflammatory associated autoimmune disorders. MicroRNA (miR)-146a plays a crucial role in regulating inflammation. A single nucleotide polymorphism in the miR-146a gene (rs2910164), aberrantly alters its gene expression and linked with the pathogenesis of several disorders, including psoriasis and PsA. In South Africa, psoriasis and PsA are extremely rare in the indigenous African population and most common in both the Indian and Caucasian population. The aim of this study was to investigate whether the miR-146a rs2910164 contributes towards psoriasis and PsA development in South African Indian and Caucasian patients. METHODS: South African Indian (n = 84) and Caucasian (n = 32) PsA patients (total n = 116) and healthy control subjects (Indian: n = 62 and Caucasian: n = 38; total n = 100) were recruited in the study. DNA was extracted from whole blood taken from all subjects, and genotyped for the miR-146a rs2910164 using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Data for laboratory parameters were obtained from pathology reports. The consulting rheumatologist collected all other clinical data. RESULTS: Unstratified data (Caucasians + Indians): A significant decrease in C-reactive protein (CRP) levels in PsA patients was observed (CRP monitored at inclusion vs. after 6 months of treatment) (18.95 +/- 2.81 mg/L vs. 9.68 +/- 1.32 mg/L, p = 0.0011). The miR-146a rs2910164 variant C-allele frequency in PsA patients was significantly higher vs. healthy controls (35.78% vs. 26% respectively, p = 0.0295, OR = 1.59 95% CI 1.05-2.40). Stratified data (Indians): The variant C-allele frequency in Indian PsA patients was significantly higher vs. healthy Indian controls (35.71% vs. 22.58%, p = 0.0200, OR = 1.91 95% CI 1.13 3.22). Stratified data (Caucasians): The variant C-allele frequency distribution between Caucasian PsA patients and healthy Caucasian controls was similar. CONCLUSION: The rs2910164 variant C-allele may play a role in the progression of PsA in the South African Indian population. The main limitation in this study was the small sample size in the case-control cohorts, with a low overall statistical power (post-hoc power analysis = 19%). PMID- 29587641 TI - The prevalence of heterozygous F12 mutations in Chinese population and its relevance to incidents of thrombosis. AB - BACKGROUND: The contribution of moderate coagulation factor XII (FXII) deficiency to development of thromboembolism is still undetermined. We have tried to show the relevance of FXII deficiency to incidences of venous thrombosis by exploring the prevalence of F12 gene mutations in Chinese patients with thrombotic disorders. METHODS: One hundred and six patients with venous thromboembolism (VTE) and 220 healthy controls were enrolled in study. The coding region and flanking sequences of F12 gene were amplified and sequenced to identify genetic variances. Patients with F12 mutations were also screened for other thrombotic risk factors. RESULTS: Heterozygous F12 gene mutations were identified in 6 individuals with VTE and 10 healthy controls. Q336X and R66W were found in two healthy individuals; D291E was identified in a patient with DVT; and A343P was a recurrent mutation with a prevalence of 4.7% (5/106) in patient group and 3.6%(8/220) in healthy control. The prevalence of heterozygous mutations between the two groups had no significant difference. The association of A343P mutations with VTE was weak with an OR of 1.31 (95% CI 0.42-4.11). No other thrombophilia risk factors screened were positive in patients harboring heterozygous F12 mutations. CONCLUSIONS: There were conflicting theories about the relationship between FXII deficiency and thrombosis formation. Heterozygous F12 mutation decreases the plasma FXII activity approximately by half and cause moderate FXII deficiency. Although multiple mutations were identified in both groups, the link between F12 heterozygous mutation and development of thrombotic disorders is weak and further studies are warranted to clarify their relationship. PMID- 29587640 TI - Spoligotyping based genetic diversity of Mycobacterium tuberculosis in Ethiopia: a systematic review. AB - BACKGROUND: Understanding the types of strains and lineages of Mycobacterium tuberculosis (M. tuberculosis) circulating in a country is of paramount importance for tuberculosis (TB) control program of that country. The main aim of this study was to review and compile the results of studies conducted on strains and lineages of M. tuberculosis in Ethiopia. METHODS: A systematic search and review of articles published on M. tuberculosis strains and lineages in Ethiopia were made. PubMed and Google Scholar databases were considered for the search while the keywords used were M. tuberculosis, molecular epidemiology, molecular typing spoligotyping and Ethiopia. RESULT: Twenty-one studies were considered in this review and a total of 3071 M. tuberculosis isolates and 3067 strains were included. These studies used spoligotyping and identified five lineages including Indo-Ocean, East Asian/Beijing, East African-Indian, Euro-American and Ethiopian in a proportion of 7.1%, 0.2%, 23.0%, 64.8%, and 4.1%, respectively. Thus, Euro American was the most frequently (64.8%) occurring Lineage while East Asian was the least (0.2%) frequently occurring Lineage in the country. Surprisingly, the Ethiopian Lineage seemed to be localized to northeastern Ethiopia. In addition, the top five clades identified by this review were T, CAS, H, Manu and Ethiopian comprising of 48.0%, 23.0%, 11.0%, 6.0% and 4.1% of the strains, respectively. Furthermore, predominant shared types (spoligotype patterns) identified were SIT149, SIT53, SIT25, SIT37, and SIT21, each consisting of 420, 343, 266, 162 and 102 isolates, respectively, while, on the other hand, 15% of the strains were orphan. CONCLUSION: According to the summary of the results of this review, diversified strains and lineages of M. tuberculosis were found in Ethiopia, and the frequencies of occurrence of these strains and lineages were variable in different regions of the country. This systematic review is registered in the PRISMA with the registration number of 42017059263. PMID- 29587642 TI - Guillain-Barre syndrome associated with hemorrhagic fever with renal syndrome in China: a case report. AB - BACKGROUND: We describe a case of Guillain-Barre syndrome (GBS) associated with hemorrhagic fever with renal syndrome. To our knowledge, only five cases of GBS associated with Hantavirus infection have been reported so far. CASE PRESENTATIONS: A 62-year-old man presented intermittent fever, chill and oliguria. According to remarkable leukocytosis, atypical lymphocytes, thrombocytopenia and former dwelling in hemorrhagic fever-endemic area, he was suspected as hemorrhagic fever with renal syndromeand certified with positive Hantavirus IgG. Later, the patient had symmetrical flaccid paralysis of all extremities. Electromyography showed peripheral nerve injury (mainly in axon). The patient was diagnosed as having acute motor sensory axonal neuropathy (AMSAN). After immunoglobulin infusion, patient showed progressive recovery and was transferred 3 weeks after his first admission to a rehabilitation center. CONCLUSIONS: Our case was the 6th reported case of GBS associated with hemorrhagic fever with renal syndrome. Moreover, we for the first time classified the subtype of GBS (AMSAN) based on the electrophysiology characteristics. GBS should be suspected in patients who are already diagnosed as hemorrhagic fever with renal syndrome when delayed symmetrical limb paralysis occurs. Until recent now, GBS was only reported in hemorrhagic fever patients in Europe and Asia, which termed as hemorrhagic fever with renal syndrome. PMID- 29587643 TI - The influence of host genotype and salt stress on the seed endophytic community of salt-sensitive and salt-tolerant rice cultivars. AB - BACKGROUND: Inherent characteristics and changes in the physiology of rice as it attains salt tolerance affect the colonizing bacterial endophytic communities of the rice seeds. These transmissible endophytes also serve as a source of the plant's microbial community and concurrently respond to the host and environmental conditions. This study explores the influence of the rice host as well as the impact of soil salinity on the community structure and diversity of seed bacterial endophytes of rice with varying tolerance to salt stress. Endophytic bacterial diversity was studied through culture-dependent technique and Terminal-Restriction Fragment Length Polymorphism (T-RFLP) analysis. RESULTS: Results revealed considerably diverse communities of bacterial endophytes in the interior of rice seeds. The overall endophytic bacterial communities of the indica rice seeds based on 16S rRNA analysis of clones and isolates are dominated by phylum Proteobacteria followed by Actinobacteria and Firmicutes. Community profiles show common ribotypes found in all cultivars of the indica subspecies representing potential core microbiota belonging to Curtobacterium, Flavobacterium, Enterobacter, Xanthomonas, Herbaspirillum, Microbacterium and Stenotrophomonas. Clustering analysis shows that the host genotype mainly influences the seed endophytic community of the different rice cultivars. Under salt stress conditions, endophytic communities of the salt-sensitive and salt tolerant rice cultivars shift their dominance to bacterial groups belonging to Flavobacterium, Pantoea, Enterobacter, Microbacterium, Kosakonia and Curtobacterium. CONCLUSION: The endophytic communities of rice indica seeds are shaped by the hosts' genotype, their physiological adaptation to salt stress and phylogenetic relatedness. Under salt stress conditions, a few groups of bacterial communities become prominent causing a shift in bacterial diversity and dominance. PMID- 29587644 TI - A novel germline ARMC5 mutation in a patient with bilateral macronodular adrenal hyperplasia: a case report. AB - BACKGROUND: Bilateral macronodular adrenal hyperplasia (BMAH) is a rare cause of Cushing's syndrome (CS). BMAH is predominantly believed to be caused by two mutations, a germline and somatic one, respectively, as described in the two-hit hypothesis. In many familial cases of BMAH, mutations in armadillo repeat containing 5 (ARMC5), a putative tumor suppressor gene, are thought to induce the disorder. The objective of this study was to report a case in which the patient presented with BMAH induced by a novel heterozygous germline ARMC5 mutation (c. 517C > T, p. Arg173*) alone rather than a two-hit mutation. CASE PRESENTATION: A 51-year-old woman was identified with masses in the bilateral adrenals. Serum cortisol levels were increased significantly both in the morning (08:00 AM) and late at night (24:00 AM), while plasma adrenocorticotropic hormone was normal. The patient underwent a left adrenalectomy and histopathology substantiated the BMAH diagnosis. WES of the germline DNA discovered a novel heterozygous germline ARMC5 mutation (c. 517C > T, p. Arg173*) and in silico analysis predicted that the mutation significantly impaired protein function, resulting in inactivated ARMC5. Subsequently, WES of the tumor specimen identified 79 somatic single nucleotide polymorphisms (SNPs)/insertion-deletion (indel) mutations, including 32 missense/nonsense/splice/stop-loss mutations. None of these mutations were CS related. CONCLUSIONS: A novel germline ARMC5 mutation (c. 517C > T, p. Arg173*) was identified that induced BMAH alone without a second mutation. ARMC5 sequencing may improve the identification of clinical forms of BMAH and allow earlier diagnosis of this disease. PMID- 29587645 TI - CarrierSeq: a sequence analysis workflow for low-input nanopore sequencing. AB - BACKGROUND: Long-read nanopore sequencing technology is of particular significance for taxonomic identification at or below the species level. For many environmental samples, the total extractable DNA is far below the current input requirements of nanopore sequencing, preventing "sample to sequence" metagenomics from low-biomass or recalcitrant samples. RESULTS: Here we address this problem by employing carrier sequencing, a method to sequence low-input DNA by preparing the target DNA with a genomic carrier to achieve ideal library preparation and sequencing stoichiometry without amplification. We then use CarrierSeq, a sequence analysis workflow to identify the low-input target reads from the genomic carrier. We tested CarrierSeq experimentally by sequencing from a combination of 0.2 ng Bacillus subtilis ATCC 6633 DNA in a background of 1000 ng Enterobacteria phage lambda DNA. After filtering of carrier, low quality, and low complexity reads, we detected target reads (B. subtilis), contamination reads, and "high quality noise reads" (HQNRs) not mapping to the carrier, target or known lab contaminants. These reads appear to be artifacts of the nanopore sequencing process as they are associated with specific channels (pores). CONCLUSION: By treating sequencing as a Poisson arrival process, we implement a statistical test to reject data from channels dominated by HQNRs while retaining low-input target reads. PMID- 29587646 TI - A hidden Markov tree model for testing multiple hypotheses corresponding to Gene Ontology gene sets. AB - BACKGROUND: Testing predefined gene categories has become a common practice for scientists analyzing high throughput transcriptome data. A systematic way of testing gene categories leads to testing hundreds of null hypotheses that correspond to nodes in a directed acyclic graph. The relationships among gene categories induce logical restrictions among the corresponding null hypotheses. An existing fully Bayesian method is powerful but computationally demanding. RESULTS: We develop a computationally efficient method based on a hidden Markov tree model (HMTM). Our method is several orders of magnitude faster than the existing fully Bayesian method. Through simulation and an expression quantitative trait loci study, we show that the HMTM method provides more powerful results than other existing methods that honor the logical restrictions. CONCLUSIONS: The HMTM method provides an individual estimate of posterior probability of being differentially expressed for each gene set, which can be useful for result interpretation. The R package can be found on https://github.com/k22liang/HMTGO . PMID- 29587647 TI - Study of morphological variation of northern Neotropical Ariidae reveals conservatism despite macrohabitat transitions. AB - BACKGROUND: Morphological convergence triggered by trophic adaptations is a common pattern in adaptive radiations. The study of shape variation in an evolutionary context is usually restricted to well-studied fish models. We take advantage of the recently revised systematics of New World Ariidae and investigate skull shape evolution in six genera of northern Neotropical Ariidae. They constitute a lineage that diversified in the marine habitat but repeatedly adapted to freshwater habitats. 3D geometric morphometrics was applied for the first time in catfish skulls and phylogenetically informed statistical analyses were performed to test for the impact of habitat on skull diversification after habitat transition in this lineage. RESULTS: We found that skull shape is conserved throughout phylogeny. A morphospace analysis revealed that freshwater and marine species occupy extreme ends of the first principal component axis and that they exhibit similar Procrustes variances. Yet freshwater species occupy the smallest shape space compared to marine and brackish species (based on partial disparity), and marine and freshwater species have the largest Procrustes distance to each other. We observed a single case of shape convergence as derived from 'C-metrics', which cannot be explained by the occupation of the same habitat. CONCLUSIONS: Although Ariidae occupy such a broad spectrum of different habitats from sea to freshwater, the morphospace analysis and analyses of shape and co-variation with habitat in a phylogenetic context shows that conservatism dominates skull shape evolution among ariid genera. PMID- 29587648 TI - Identification of cold stress responsive microRNAs in two winter turnip rape (Brassica rapa L.) by high throughput sequencing. AB - BACKGROUND: Low temperature is a major abiotic stress affecting the production of rapeseed in China by impeding plant growth and development. A comprehensive knowledge of small-RNA expression pattern in Brassica rapa under cold stress could improve our knowledge of microRNA-mediated stress responses. RESULTS: A total of 353 cold-responsive miRNAs, 84 putative novel and 269 conserved miRNAs, were identified from the leaves and roots of two winter turnip rape varieties 'Longyou 7' (cold-tolerant) and 'Tianyou 4' (cold-sensitive), which were stressed under - 4 degrees C for 8 h. Eight conserved (miR166h-3p-1, miR398b-3p, miR398b 3p-1, miR408d, miR156a-5p, miR396h, miR845a-1, miR166u) and two novel miRNAs (Bra novel-miR3153-5p and Bra-novel-miR3172-5p) were differentially expressed in leaves of 'Longyou 7' under cold stress. Bra-novel-miR3936-5p was up-regulated in roots of 'Longyou 7' under cold stress. Four and five conserved miRNAs were differentially expressed in leaves and roots of 'Tianyou 4' after cold stress. Besides, we found two conserved miRNAs (miR319e and miR166m-2) were down regulated in non-stressed roots of 'Longyou 7' compared with 'Tianyou 4'. After cold stress, we found two and eight miRNAs were differentially expressed in leaves and roots of 'Longyou 7' compared with 'Tianyou 4'. The differentially expressed miRNAs between two cultivars under cold stress include novel miRNAs and the members of the miR166 and miR319 families. A total of 211 target genes for 15 known miRNAs and two novel miRNAs were predicted by bioinformatic analysis, mainly involved in metabolic processes and stress responses. Five differentially expressed miRNAs and predicted target genes were confirmed by quantitative reverse transcription PCR, and the expressional changes of target genes were negatively correlated to differentially expressed miRNAs. Our data indicated that some candidate miRNAs (e.g., miR166e, miR319, and Bra-novel-miR3936-5p) may play important roles in plant response to cold stress. CONCLUSIONS: Our work indicates that miRNA and putative target genes mediated metabolic processes and stress responses are significant to cold tolerance in B. rapa. PMID- 29587649 TI - Factors associated with human West Nile virus infection in Ontario: a generalized linear mixed modelling approach. AB - BACKGROUND: West Nile Virus (WNV) is a mosquito-borne pathogen that has become established in North America. Risk for human infection varies geographically in accordance with climate and population factors. Though often asymptomatic, human WNV infection can cause febrile illness or, rarely, neurologic disease. WNV has become a public health concern in Canada since its introduction in 2001. METHODS: To identify predictors of human WNV incidence at the public health unit (PHU) level in Ontario, Canada, we combined data on environmental and population characteristics of PHUs with historical mosquito and human surveillance records from 2002 to 2013. We examined the associations between annual WNV incidence and monthly climate indices (e.g. minimum and maximum temperature, average precipitation), land cover (e.g. deciduous forest, water), population structure (e.g. age and sex composition) and the annual percentage of WNV-positive mosquito pools from 2002 to 2013. We then developed a generalized linear mixed model with a Poisson distribution adjusting for spatial autocorrelation and repeat measures. Further to this, to examine potential 'early season' predictors of WNV incidence in a given year, we developed a model based on winter and spring monthly climate indices. RESULTS: Several climate indices, including mean minimum temperature (o C) in February (RR = 1.58, CI: [1.42, 1.75]), and the annual percentage of WNV positive mosquito pools (RR = 1.07, CI: [1.04, 1.11]) were significantly associated with human WNV incidence at the PHU level. Higher winter minimum temperatures were also strongly associated with annual WNV incidence in the 'early season' model (e.g. February minimum temperature (RR = 1.91, CI: [1.73, 2.12]). CONCLUSIONS: Our study demonstrates that early season temperature and precipitation indices, in addition to the percentage of WNV-positive mosquito pools in a given area, may assist in predicting the likelihood of a more severe human WNV season in southern regions of Ontario, where WNV epidemics occur sporadically. PMID- 29587650 TI - Biopsy-proven vancomycin-induced acute kidney injury: a case report and literature review. AB - BACKGROUND: Vancomycin is the first-line antibiotic for methicillin-resistant Staphylococcus aureus and coagulase-negative strains. The risk of vancomycin induced acute kidney injury increases with plasma vancomycin levels. Vancomycin induced acute kidney injury is histologically characterized by acute interstitial nephritis and/or acute tubular necrosis. However, only 12 biopsy-proven cases of vancomycin-induced acute kidney injury have been reported so far, as renal biopsy is rarely performed for such cases. Current recommendations for the prevention or treatment of vancomycin-induced acute kidney injury are drug monitoring of plasma vancomycin levels using trough level and drug withdrawal. Oral prednisone and high-flux haemodialysis have led to the successful recovery of renal function in some biopsy-proven cases. CASE PRESENTATION: We present the case of a 41-year-old man with type 1 diabetes mellitus, who developed vancomycin-induced acute kidney injury during treatment for Fournier gangrene. His serum creatinine level increased to 1020.1 MUmol/L from a baseline of 79.6 MUmol/L, and his plasma trough level of vancomycin peaked at 80.48 MUg/mL. Vancomycin discontinuation and frequent haemodialysis with high-flux membrane were immediately performed following diagnosis. Renal biopsy showed acute tubular necrosis and focal acute interstitial nephritis, mainly in the medullary rays (medullary ray injury). There was no sign of glomerulonephritis, but mild diabetic changes were detected. He was discharged without continuing haemodialysis (serum creatinine level, 145.0 MUmol/L) 49 days after initial vancomycin administration. CONCLUSIONS: This case suggests that frequent haemodialysis and renal biopsy could be useful for the treatment and assessment of vancomycin-induced acute kidney injury, particularly in high-risk cases or patients with other renal disorders. PMID- 29587651 TI - Pretreatment loss to follow-up of tuberculosis patients in Chennai, India: a cohort study with implications for health systems strengthening. AB - BACKGROUND: Pretreatment loss to follow-up (PTLFU) is a barrier to tuberculosis (TB) control in India's Revised National TB Control Programme (RNTCP). PTLFU studies have not been conducted in India's mega-cities, where patient mobility may complicate linkage to care. METHODS: We collected data from patient registries for May 2015 from 22 RNTCP designated microscopy centers (DMCs) in Chennai and audited addresses and phone numbers for patients evaluated for suspected TB to understand how missing contact information may contribute to PTLFU. From November 2015 to June 2016, we audited one month of records from each of these 22 DMCs and tracked newly diagnosed smear-positive patients using RNTCP records, phone calls, and home visits. We defined PTLFU cases as including: (1) patients who did not start TB therapy within 14 days and (2) patients who started TB therapy but were lost to follow-up or died before official RNTCP registration. We used multivariate logistic regression to identify factors associated with PTLFU. RESULTS: In the audit of May 2015 DMC registries, out of 3696 patients evaluated for TB, 1273 (34.4%) had addresses and phone numbers that were illegible or missing. Out of 344 smear-positive patients tracked from November 2015 to June 2016, 40 (11.6%) did not start TB therapy within 14 days and 36 (10.5%) started therapy but were lost to follow-up or died before official RNTCP registration, for an overall PTLFU rate of 22.1% (95%CI: 17.8%-26.4%). Of all PTLFU patients, 55 (72.4%) were lost to follow-up and 21 (27.6%) died before starting treatment or before RNTCP registration. In the regression analysis, age > 50 years (OR 2.9, 95%CI 1.4-6.5), history of prior TB (OR 3.9, 95%CI 2.2-7.1), evaluation at a high patient volume DMC (OR 3.2, 95% CI 1.7-6.3), and absence of legible patient contact information (OR 4.5, 95%CI 1.3-15.1) were significantly associated with PTLFU. CONCLUSIONS: In an Indian mega-city, we found a high PTLFU rate, especially in patients with a prior TB history, who are at greater risk for having drug-resistance. Enhancing quality of care and health system transparency is critical for improving linkage of newly diagnosed patients to TB care in urban India. PMID- 29587652 TI - Quantitative profiling of BATF family proteins/JUNB/IRF hetero-trimers using Spec seq. AB - BACKGROUND: BATF family transcription factors (BATF, BATF2 and BATF3) form hetero trimers with JUNB and either IRF4 or IRF8 to regulate cell fate in T cells and dendritic cells in vivo. While each combination of the hetero-trimer has a distinct role, some degree of cross-compensation was observed. The basis for the differential actions of IRF4 and IRF8 with BATF factors and JUNB is still unknown. We propose that the differences in function between these hetero-trimers may be caused by differences in their DNA binding preferences. While all three BATF family transcription factors have similar binding preferences when binding as a hetero-dimer with JUNB, the cooperative binding of IRF4 or IRF8 to the hetero-dimer/DNA complex could change the preferences. We used Spec-seq, which allows for the efficient and accurate determination of relative affinity to a large collection of sequences in parallel, to find differences between cooperative DNA binding of IRF4, IRF8 and BATF family members. RESULTS: We found that without IRF binding, all three hetero-dimer pairs exhibit nearly the same binding preferences to both expected wildtype binding sites TRE (TGA(C/G)TCA) and CRE (TGACGTCA). IRF4 and IRF8 show the very similar DNA binding preferences when binding with any of the three hetero-dimers. No major change of binding preferences was found in the half-sites between different hetero-trimers. IRF proteins bind with substantially lower affinity with either a single nucleotide spacer between IRF and BATF binding site or with an alternative mode of binding in the opposite orientation. In addition, the preference to CRE binding site was reduced with either IRF binding in all BATF-JUNB combinations. CONCLUSIONS: The specificities of BATF, BATF2 and BATF3 are all very similar as are their interactions with IRF4 and IRF8. IRF proteins binding adjacent to BATF sites increases affinity substantially compared to sequences with spacings between the sites, indicating cooperative binding through protein-protein interactions. The preference for the type of BATF binding site, TRE or CRE, is also altered when IRF proteins bind. These in vitro preferences aid in the understanding of in vivo binding activities. PMID- 29587653 TI - Efficient anchoring of alien chromosome segments introgressed into bread wheat by new Leymus racemosus genome-based markers. AB - BACKGROUND: The tertiary gene pool of bread wheat, to which Leymus racemosus belongs, has remained underutilized due to the current limited genomic resources of the species that constitute it. Continuous enrichment of public databases with useful information regarding these species is, therefore, needed to provide insights on their genome structures and aid successful utilization of their genes to develop improved wheat cultivars for effective management of environmental stresses. RESULTS: We generated de novo DNA and mRNA sequence information of L. racemosus and developed 110 polymorphic PCR-based markers from the data, and to complement the PCR markers, DArT-seq genotyping was applied to develop additional 9990 SNP markers. Approximately 52% of all the markers enabled us to clearly genotype 22 wheat-L. racemosus chromosome introgression lines, and L. racemosus chromosome-specific markers were highly efficient in detailed characterization of the translocation and recombination lines analyzed. A further analysis revealed remarkable transferability of the PCR markers to three other important Triticeae perennial species: L. mollis, Psathyrostachys huashanica and Elymus ciliaris, indicating their suitability for characterizing wheat-alien chromosome introgressions carrying chromosomes of these genomes. CONCLUSION: The efficiency of the markers in characterizing wheat-L. racemosus chromosome introgression lines proves their reliability, and their high transferability further broadens their scope of application. This is the first report on sequencing and development of markers from L. racemosus genome and the application of DArT-seq to develop markers from a perennial wild relative of wheat, marking a paradigm shift from the seeming concentration of the technology on cultivated species. Integration of these markers with appropriate cytogenetic methods would accelerate development and characterization of wheat-alien chromosome introgression lines. PMID- 29587654 TI - Antepartum urinary tract infection and postpartum depression in Taiwan - a nationwide population-based study. AB - BACKGROUND: Urinary tract infections (UTIs) are among the most common bacterial infections in pregnant women due to anatomic and physiologic changes in the female urinary tract during pregnancy, and antepartum UTIs can cause adverse pregnancy outcomes that may induce mental stress. There have only been a few studies, however, investigating antepartum UTIs and mental stress. As such, the present study was conducted in order to investigate the association between antepartum UTIs and postpartum depression (PPD). METHODS: We used data from the 2000-2013 National Health Insurance Research Database (NHIRD) of Taiwan. Data regarding a total of 55,087 singleton pregnancies was utilized, including data regarding 406 women who were newly diagnosed with PPD in the first 6 months postpartum. The associations between PPD and antepartum UTIs or other risk factors were examined by multiple logistic regression analysis. RESULTS: The logistic regression analysis results indicated that PPD was associated with antepartum UTIs (adjusted odds ratio [aOR] 1.27; 95% confidence interval [CI] (1.07-1.65). Furthermore, the risk of PPD was higher in women with an upper antepartum UTI (aOR 2.97 (1.31, 6.77) than in those with a lower antepartum UTI (aOR 1.21 (1.02, 1.58)). CONCLUSIONS: Antepartum UTIs, particularly upper antepartum UTIs, are significantly associated with PPD. This information may encourage physicians to pay greater attention to the mental health of women who have suffered upper UTIs during their pregnancies. PMID- 29587655 TI - Impedance cardiography as tool for continuous hemodynamic monitoring during cesarean section: randomized, prospective double blind study. AB - BACKGROUND: Impedance Cardiography (ICG) is a non-invasive tool for continuous hemodynamic monitoring. Aims of our study were to assess the utility of ICG to evaluate the hemodynamic impact of 6 mg (GL6) vs 8 mg (GL8) levobupivacaine combined with fentanyl in healthy patients undergoing elective cesarean section; secondary, to compare the duration and quality of analgesia and anesthesia. METHODS: Sixty-two women receiving combined spinal-epidural (CSE) for elective cesarean delivery were randomly allocated to GL6 or GL8 groups. Mean arterial pressure (MAP), cardiac index (CI), systemic vascular resistance index (SVRI), heart rate (HR), stroke volume index (SVI) were recorded from Tbaseline to 31 min after CSE by ICG. Sensory and motor blocks, patients and surgeons satisfaction, neonatal data were also recorded. RESULTS: Fifteen of 32 patients in GL6 and 15 of 30 patients in GL8 experienced hypotension at T2 vs Tbaseline (P < .001) and SVRI reduction (P = .035 and P < .001 respectively). MAP, CI and SVRI were always slightly higher in GL6 vs GL8. HR and SVI remained stable until the end of surgery in all patients. Total ephedrine requirements was higher in GL8 (P = .010). The onset and offset time of sensory and motor block were similar in both groups, but the number of patients with motor block was lower in GL6 vs GL8 (P = .001). Patients and surgeon satisfaction scores, the number of patients needed systemic rescue doses, neonatal data were similar in both groups. CONCLUSIONS: ICG is a useful noninvasive tool to monitor continuously hemodynamics during cesarean section. The hemodynamic stability, the satisfying sensory block and rapid mobilization provided by low levobupivacaine dose may be particularly advantageous in obstetric patients. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03170427 . Retrospectively Registered (Date of registration: May 2017). PMID- 29587656 TI - Erlotinib treatment after platinum-based therapy in elderly patients with non small-cell lung cancer in routine clinical practice - results from the ElderTac study. AB - BACKGROUND: In this prospective non-interventional study, the effectiveness and tolerability of erlotinib in elderly patients with non-small-cell lung cancer (NSCLC) after >=1 platinum-based chemotherapy were assessed. METHODS: A total of 385 patients >=65 years of age with advanced NSCLC receiving erlotinib were observed over 12 months. The primary endpoint was the 1-year overall survival (OS) rate. RESULTS: Patients were predominantly Caucasian (99.2%), a mean of 73 years old; 24.7% had an Eastern Cooperative Oncology Group performance status (ECOG PS) >=2. Most common tumor histologies were adenocarcinoma (64.9%) and squamous cell carcinoma (22.3%). Of 119 patients tested, 15.1% had an activating epidermal growth factor receptor gene (EGFR) mutation. The 1-year OS rate was 31% (95% CI 25-36) with a median OS of 7.1 months (95% CI 6.0-7.9). OS was significantly better in females than males (p = 0.0258) and in patients with an EGFR mutation compared to EGFR wild-type patients (p = 0.0004). OS was not affected by age (p = 0.3436) and ECOG PS (p = 0.5364). Patients with squamous NSCLC tended to live longer than patients with non-squamous EGFR wild-type tumors (median OS: 8.6 vs 5.5 months). Cough and dyspnea improved during the observation period. The erlotinib safety profile was comparable to that in previous studies with rash (45.2%) and diarrhea (22.6%) being the most frequently reported adverse events. CONCLUSIONS: Erlotinib represents a suitable palliative treatment option in further therapy lines for elderly patients with advanced NSCLC.

PMID- 29587657 TI - Effective treatment of apatinib in desmoplastic small round cell tumor: a case report and literature review. AB - BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is a rare malignant sarcoma with poor prognosis due to lack of effective treatments. Apatinib is a new potent oral small-molecule tyrosine kinase inhibitor, and targets the intracellular domain of vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we presented a case of intra-abdominal DSRCT which was effectively treated by apatinib. CASE PRESENTATION: A 32-year-old man was admitted due to increasing urination frequency and palpable mass in right lower abdomen for 2 months. The mass was resected and diagnosed DSRCT. The patient refused chemotherapy and radiotherapy,and used Chinese medicine only. Six months after the surgery, the patient re-hospitalized due to growing abdominal mass and ascites. Intraperitoneal cisplatin treatment showed little effect. Apatinib was then recommended. Apatinib revealed outstanding effect on reducing mass size and ascites during 2-month treatment. Apatinib therapy continued for additional 2 months, and the patient was in good condition. The only toxicity was hand-food syndrome, which was controllable and well tolerated. CONCLUSION: It is the first report that apatinib is effective on DSRCT. This report may provide an additional option for the treatment of metastatic DSRCT. PMID- 29587658 TI - De-medicalization of birth by reducing the use of oxytocin for augmentation among first-time mothers - a prospective intervention study. AB - BACKGROUND: The use of synthetic oxytocin for augmentation of labor is rapidly increasing worldwide. Hyper-stimulation is the most significant side effect, which may cause fetal distress and operative delivery. We performed an intervention consisting of an educational program and modified guidelines to achieve a more appropriate use of oxytocin. METHODS: This prospective intervention study included 431 first-time mothers at term with spontaneous onset of labor before (October 2012 to May 2013), and 664 after the intervention (April 2014 to April 2015). Our outcomes were prevalence and duration of oxytocin treatment, mode of delivery, indication for operative delivery, episiotomy, anal sphincter tears, bleeding, labor duration, pain relief and the effect of oxytocin on mode of delivery. RESULTS: After the intervention, 52.9% were diagnosed with dystocia, compared with 68.9% before (p < 0.001). Oxytocin was not always used in accordance with the guidelines, but a significant reduction in oxytocin rates from 63.3% to 54.1% (p < 0.001) was obtained. More women without dystocia according to the existing guidelines were augmented after the intervention (18.9% vs 8.4%, p < 0.001). Assessing all labors, the median duration of oxytocin treatment was reduced by 72% (from 90 to 25 min) without increasing the median duration of labor (385 min in both groups). There was a moderate reduction in operative vaginal deliveries from 26.9 to 21.5% (p = 0.04), and dystocia as an indication for these deliveries increased (p = 0.01). There was a moderate increase in caesarean sections from 6.7 to 10.2% (p = 0.05), but no increase in dystocia as an indication for these deliveries. Women receiving oxytocin were more likely to have an operative vaginal birth, even after adjusting for birth weight, epidural analgesia and labor duration, OR: 2.1 (CI 1.1-4.0) before and OR 2.7 (CI 1.6-4.5) after the intervention. CONCLUSIONS: Our intervention led to a significant reduction in the use of oxytocin. However, more than half of the women remained diagnosed with dystocia. Operative vaginal births seem to be associated with oxytocin treatment. Therefore, augmentation with oxytocin should be used with caution and only when medically indicated. Even more modified guidelines for augmentation than the ones applied in this study might be appropriate. PMID- 29587659 TI - Detection of circulating tumor cells in patients with pituitary tumors. AB - BACKGROUND: Circulating tumor cells (CTCs) are tumor cells that have shed from a primary tumor and circulate in the peripheral blood. Recent experimental and clinical studies show that CTCs can be detected in early-stage disease. CASE PRESENTATION: We report three cases of pituitary adenoma (PA) in which tumor cells with particles were detected in the interstitial vascular compartment by transmission electron microscopy. Tumors were completely resected. Immunohistochemical analysis showed a beta-catenin score of 10.5 +/- 1.5 in the three cases with CTCs compared with 2.4 +/- 0.5 in 24 control adenomas. The Ki-67 labeling index was 2.1 +/- 0.7 in CTCs vs. 0.2 +/- 0.3 in control cases (p = 0.043), and the p53 score was 4.33 +/- 1.3 vs. 0.31 +/- 0.17 (p = 0.000). The E cadherin score did not differ significantly between the two groups. CONCLUSIONS: CTCs can be detected in benign tumors such as PAs and not only in late-stage malignant tumors with apparent distant metastases. The present findings suggest that pituitary carcinomas develop from adenomas. PMID- 29587660 TI - Patterns of follow up and survivorship care for people with colorectal cancer in new South Wales, Australia: a population-based survey. AB - BACKGROUND: The incidence and survival rates for colorectal cancer in Australia are among the highest in the world. With population growth and ageing there are increasing numbers of colorectal cancer survivors in the community, yet little is known of their ongoing follow up and survivorship care experiences. This study investigated patterns and predictors of follow up and survivorship care received and recommended for adults with colorectal cancer in New South Wales (NSW), Australia. METHODS: Cross-sectional analysis within the NSW Bowel Cancer Care Survey, a population-based cohort of adults diagnosed with colorectal cancer between April 2012 and May 2013 in NSW. One year after diagnosis, participants completed a study specific questionnaire about their follow up and survivorship care experience and plans. Logistic regression was used to identify independent predictors of guideline-recommended care. RESULTS: Of 1007 eligible people, 560 (56%) participated in the NSW Bowel Cancer Care Survey with 483 (86% of study participants, 48% of invited sample) completing the survivorship survey. Among these 483 participants, only 110 (23%, 95% Confidence Interval CI 19-27%) had received a written follow up plan, with this more common among migrants, non urban dwellers and those with little experience of the health system. Of 379 (78%) people treated with curative intent, most were receiving ongoing colorectal cancer follow up from multiple providers with 28% (23-32%) attending three or more different doctors. However, less than half had received guideline recommended follow-up colonoscopy (46%, CI 41-51%) or carcino-embryonic antigen assay (35%, CI 30-40%). Socio-economic advantage was associated with receipt of guideline-recommended care. While participants reported high interest in improving general health and lifestyle since their cancer diagnosis, few had received advice about screening for other cancers (24%, CI 19-28%) or assistance with lifestyle modification (30%, CI 26-34%). Less than half (47%, CI 43-52%) had discussed their family's risk of cancer with a doctor since their diagnosis. CONCLUSIONS: Survivorship care was highly variable, with evident socioeconomic disparities and missed opportunities for health promotion. PMID- 29587661 TI - Characteristics and outcome of the COEUR Canadian validation cohort for ovarian cancer biomarkers. AB - BACKGROUND: Ovarian carcinoma is the most lethal gynecological malignancy due to early dissemination and acquired resistance to platinum-based chemotherapy. Reliable markers that are independent and complementary to clinical parameters are needed to improve the management of patients with this disease. The Canadian Ovarian Experimental Unified Resource (COEUR) provides researchers with biological material and associated clinical data to conduct biomarker validation studies. Using standards defined by the Canadian Tissue Repository Network (CTRNet), we have previously demonstrated the quality of the biological material from this resource. Here we describe the clinical characteristics of the COEUR cohort. METHODS: With support from 12 Canadian ovarian cancer biobanks in Canada, we created a central retrospective cohort comprised of more than 2000 patient tissue samples with associated clinical data, including 1246 high-grade serous, 102 low-grade serous, 295 endometrioid, 259 clear cell and 89 mucinous carcinoma histotypes. A two-step reclassification process was applied to assure contemporary histological classification (histotyping). For each histotypes individually, we evaluated the association between the known clinico-pathological parameters (stage, cytoreduction, chemotherapy treatment, BRCA1 and BRCA2 mutation) and patient outcome by using Kaplan-Meier and Cox proportional hazard regression analyses. RESULTS: The median follow-up time of the cohort was 45 months and the 5-year survival rate for patients with high-grade serous carcinomas was 34%, in contrast to endometrioid carcinomas with 80% at 5 years. Survival profiles differed by histotype when stratified by stage or cytoreduction. Women with mucinous or clear cell carcinomas at advanced stage or with non-optimally debulked disease had the worst outcomes. In high-grade serous carcinoma, we observed significant association with longer survival in women harboring BRCA1 or BRCA2 mutation as compared to patients without detectable mutation. CONCLUSIONS: Our results show the expected survival rates, as compared with current literature, in each histotype suggesting that the cohort is an unbiased representation of the five major histotypes. COEUR, a one stop comprehensive biorepository, has collected mature outcome data and relevant clinical data in a comprehensive manner allowing stratified analysis. PMID- 29587662 TI - Randomized clinical trial testing the efficacy and safety of 0.5% colchicine cream versus photodynamic therapy with methyl aminolevulinate in the treatment of skin field cancerization: study protocol. AB - BACKGROUND: The primary clinical manifestation of skin field cancerization is the presence of actinic keratoses (AKs). Current treatments for AKs related to skin field cancerization include photodynamic therapy (PDT) and colchicine. The objective of this study is to evaluate the efficacy and safety of 0.5% colchicine cream versus PDT with methyl aminolevulinate (MAL-PDT) in the treatment of skin field cancerization. METHODS: In a randomized controlled and open clinical trial with a blind histopathological and immunohistochemical analysis, 36 patients with up to 10 AKs on their forearms will be included from the outpatient clinic. The forearms will be randomized into two groups, clinically evaluated and biopsied for histopathology and immunohistochemistry (p53 and Ki67). One forearm will be treated with 0.5% colchicine cream for 10 days, and the other forearm will receive one session of MAL-PDT; the forearms will subsequently be reassessed clinically and histologically after 60 days (T60) of treatment. The primary endpoint will be the point of complete clearance of AKs in T60. The sample size will enable a detection in the reduction of over 10% in AK counts between the groups with power of 0.9 and an alpha of 0.05, accounting for an estimated dropout rate of 10%, resulting in 36 patients (72 forearms). All participants included in the randomized study will be part of the analysis, and the final outcomes of any dropouts will be the value of their last visit (LOCF). The statistical analysis will be performed using SPSS 22.0, and a p value < 5% will be considered to be significant. DISCUSSION: It is expected that colchicine will be superior to MAL-PDT in reducing AKs and in the skin field cancerization, and there will be good tolerability in both groups. Colchicine intervention is novel in that it provides a new alternative to MAL-PDT. Moreover, this drug is inexpensive that may be a potential treatment of skin field cancerization that can be prescribed in public health systems with good results. TRIAL REGISTRATION: The trial is registered in Brazilian Registry for Clinical Trials (Registration number: RBR-8y3sj9 , date assigned May 4, 2016, retrospectively registered). PMID- 29587663 TI - Development of primary human pancreatic cancer organoids, matched stromal and immune cells and 3D tumor microenvironment models. AB - BACKGROUND: Patient-derived tumor models are the new standard for pre-clinical drug testing and biomarker discovery. However, the emerging technology of primary pancreatic cancer organoids has not yet been broadly implemented in research, and complex organotypic models using organoids in co-culture with stromal and immune cellular components of the tumor have yet to be established. In this study, our objective was to develop and characterize pancreatic cancer organoids and multi cell type organotypic co-culture models to demonstrate their applicability to the study of pancreatic cancer. METHODS: We employed organoid culture methods and flow cytometric, cytologic, immunofluorescent and immunohistochemical methods to develop and characterize patient-derived pancreatic cancer organoids and multi cell type organotypic co-culture models of the tumor microenvironment. RESULTS: We describe the culture and characterization of human pancreatic cancer organoids from resection, ascites and rapid autopsy sources and the derivation of adherent tumor cell monocultures and tumor-associated fibroblasts from these sources. Primary human organoids displayed tumor-like cellular morphology, tissue architecture and polarity in contrast to cell line spheroids, which formed homogenous, non-lumen forming spheres. Importantly, we demonstrate the construction of complex organotypic models of tumor, stromal and immune components of the tumor microenvironment. Activation of myofibroblast-like cancer associated fibroblasts and tumor-dependent lymphocyte infiltration were observed in these models. CONCLUSIONS: These studies provide the first report of novel and disease-relevant 3D in-vitro models representing pancreatic tumor, stromal and immune components using primary organoid co-cultures representative of the tumor microenvironment. These models promise to facilitate the study of tumor-stroma and tumor-immune interaction and may be valuable for the assessment of immunotherapeutics such as checkpoint inhibitors in the context of T-cell infiltration. PMID- 29587664 TI - Management and obstetric outcomes of 17 heterotopic interstitial pregnancies. AB - BACKGROUND: Heterotopic interstitial pregnancy is a rare variant of heterotopic pregnancies, and it poses challenges in treating the heterotopic pregnancy and preserving the intrauterine pregnancy. However, there is no clear consensus regarding the optimal management. The aim of this study was to investigate the pregnancy outcomes of women diagnosed with heterotopic interstitial pregnancy. METHODS: A total of 17 women diagnosed with heterotopic interstitial pregnancy between July 2010 and December 2015 were included. General characteristics of each patient, including age, gravidity and parity, history of pelvic inflammatory disease or surgery, and especially the corresponding therapeutic interventions, were retrospectively analyzed. Moreover, pregnancy outcomes were further followed by face-to-face interview. RESULTS: Of the 17 patients, 10 (58.5%) underwent surgical treatment (7 laparoscopic cornual resection, and 3 laparotomy); and 3 cases simultaneously terminated the intrauterine pregnancy by suction evacuation. Compared with laparotomy, laparoscopic cornual section showed shorter operative time (median 40 vs. 70 min), less blood loss (150 vs. 400 ml) and shorter hospital stay (2 vs. 4 days). In addition, 4 (23.5%) patients underwent selective embryo reduction under transvaginal ultrasound guidance. Expectant management was chosen in the remaining 3 patients. In the follow-up study, other than a case of missed miscarriage, the other 13 women who remained committed to their pregnancies all delivered healthy babies either by caesarean section or vaginal birth. No congenital anomalies were reported, and all the infants were in good growth and development. CONCLUSIONS: Laparoscopic cornual resection is a feasible approach with favorable surgical and long-term pregnancy outcomes. Additionally, medical or expectant management may be a viable treatment option for selected symptom-free patient. Although the survival of the intrauterine pregnancy could not always be assured, the prognosis for a woman with heterotopic interstitial pregnancy is generally good. PMID- 29587665 TI - Neoadjuvant chemotherapy followed by concurrent chemoradiotherapy versus concurrent chemoradiotherapy followed by adjuvant chemotherapy in locally advanced nasopharyngeal carcinoma. AB - BACKGROUND: Concurrent chemoradiotherapy followed by adjuvant chemotherapy (CCRT AC) is currently recommended as the standard treatment for locally advanced nasopharyngeal carcinoma (LA-NPC). Neoadjuvant chemotherapy followed by concurrent chemoradiotherapy (NAC-CCRT) is an alternative strategy for decreasing tumor size and controlling micrometastases before main treatment. The aim of this study was to investigate and compare survival outcomes between LA-NPC patients treated with CCRT-AC and those treated with NAC-CCRT. METHODS: This retrospective cohort study included consecutive histologically confirmed LA-NPC patients that were treated with NAC-CCRT or CCRT-AC at Siriraj Hospital during the March 2010 to October 2014 study period. CCRT in both protocols consisted of 3-week cycles of cisplatin 100 mg/m2 with concurrent radiotherapy. Either NAC or AC consisted of 3-week cycles of cisplatin on day 1 and fluorouracil/leucovorin on days 1-4 for a maximum three cycles. The primary endpoint was 5-year overall survival (OS). Flexible parametric survival analysis was used, because the proportional hazards assumption of Cox regression was violated. RESULTS: Of the 266 LA-NPC patients that received treatment during the study period, 79 received NAC-CCRT and 187 received CCRT-AC. Median follow-up was 37 months. Significantly more patients with advanced clinical stage (stage IVA-IVB) received NAC-CCRT (86% in NAC-CCRT vs. 29% in CCRT-AC; p < 0.001). Compared to CCRT-AC in crude analysis, 3 year and 5-year OS of NAC-CCRT were 72% vs. 86% and 62% vs. 75% respectively (p = 0.059). Interestingly, the 3-year and 5-year post-estimation adjusted OS was 84% and 74% for NAC-CCRT and 81% and 70% for CCRT-AC, respectively (HR: 0.83, 95% confidence interval (CI): 0.45-1.56; p = 0.571). Also, adjusted analysis of distant-metastasis survival, NAC-CCRT showed HR was 0.79 (95% CI:0.37-1.72, p = 0.557). Conversely, adjusted analysis of locoregional relapse (LLR)-free survival revealed NAC-CCRT to have a significantly higher risk of LRR (HR: 2.18, 95% CI: 0.98-4.87; p = 0.057). CONCLUSIONS: The results suggested that prognosis in the NAC-CCRT treated patients was not superior to that of the CCRT-AC treated individuals. In patients that receive neoadjuvant chemotherapy, locoregional relapse should be of concern. High-risk distant metastasis patients (N3 stage) that could achieve survival advantage from NAC-CCRT is an interesting and important topic for further study. PMID- 29587666 TI - Cost effectiveness analysis of afatinib versus pemetrexed-cisplatin for first line treatment of locally advanced or metastatic EGFR mutation positive non-small cell lung cancer from the Singapore healthcare payer's perspective. AB - BACKGROUND: Non-small-cell lung cancer (NSCLC) accounts for 85% of all lung cancers and is associated with a poor prognosis. Afatinib is an irreversible ErbB family blocker recommended in clinical guidelines as a first-line treatment for NSCLC which harbours an epidermal growth factor receptor (EGFR) mutation. The objective of this study was to evaluate the cost-effectiveness of afatinib versus pemetrexed-cisplatin for first-line treatment of locally advanced or metastatic EGFR mutation positive NSCLC in Singapore. METHODS: A partitioned survival model with three health states (progression-free, progressive disease and death) was developed from a healthcare payer perspective. Survival curves from the LUX-Lung 3 trial (afatinib versus pemetrexed-cisplatin chemotherapy) were extrapolated beyond the trial period to estimate the underlying progression-free survival and overall survival parametric distributions. Rates of adverse reactions were also estimated from LUX-Lung 3 while health utilities from overseas were derived from the literature in the absence of local estimates. Direct costs were sourced from public healthcare institutions in Singapore. Incremental cost-effectiveness ratios (ICERs) were calculated over a 5 year time horizon. Deterministic and probabilistic sensitivity analyses and additional scenario analyses were conducted to explore the impact of uncertainties and assumptions on the cost effectiveness results. RESULTS: In the base-case analysis, the ICER for afatinib versus pemetrexed-cisplatin was SG$137,648 per quality-adjusted life year (QALY) gained and SG$109,172 per life-year gained. One-way sensitivity analysis showed the ICER was most sensitive to variations in the utility values, the cost of afatinib and time horizon. Scenario analyses showed that even reducing the cost of afatinib by 50% led to a high ICER which was unlikely to represent a cost effective use of healthcare resources. CONCLUSIONS: Compared with pemetrexed cisplatin, afatinib is not cost-effective as a first-line treatment for advanced EGFR mutation-positive NSCLC in Singapore. The findings from our study will be useful to inform local healthcare decision-making and resource allocations for NSCLC treatments, together with other considerations such as clinical effectiveness, safety and affordability of TKIs. PMID- 29587667 TI - Outcomes of Pemetrexed-based chemotherapies in HER2-mutant lung cancers. AB - BACKGROUND: HER2 mutation has been found to be an oncogenic driver gene in non small cell lung cancers(NSCLC) and HER2-directed therapies have shown promising results in this unique population, while little is known about its association with outcomes of chemotherapy. The aim of this study was to investigate the efficacy of first line chemotherapy in patients with advanced HER2-mutant lung adenocarcinomas. METHODS: Patients with advanced NSCLC(N = 1714) initially underwent testing for EGFR, KRAS, BRAF mutations and ALK, ROS1 rearrangements, and negative cases were then assessed for HER2 mutations using the method of amplification refractory mutation system(ARMS). The efficacy of first line pemetrexed-based chemotherapy was investigated in patients with HER2-mutant and those with EGFR-mutant, ALK/ROS1-rearranged and KRAS-mutant advanced adenocarcinomas. RESULTS: HER2 mutations were detected in 29 of 572(5.1%) specimens from a selected population of EGFR/KRAS/BRAF/ALK/ROS1 negative patients. All of them are adenocarcinomas. Among patients with HER2-mutant lung cancers, 25 received pemetrexed-based first line chemotherapy. The objective response rate(ORR) was 36.0%. Their median progression free survival(PFS) was 5.1 months, which was similar with that of KRAS-mutant group (n = 40,5.0 months, p = 0.971), numerically shorter than that of EGFR-mutant group(n = 74, 6.5 months, p = 0.247) and statistically significantly shorter than that of ALK/ROS1-rearranged group (n = 39,9.2 months, p = 0.004). Furthermore, HER2 variants subgroup analysis showed that PFS was inferior in A775_G776insYVMA group compared with other variants (4.2 vs 7.2 months, p = 0.085). CONCLUSIONS: Patients with advanced HER2-mutant lung adenocarcinomas showed an inferior outcome of first line pemetrexed-based chemotherapy compared to those with ALK/ROS1 rearrangements, which strengthen the need for effective HER2-targeted drugs in clinical practice. PMID- 29587668 TI - Knockdown delta-5-desaturase in breast cancer cells that overexpress COX-2 results in inhibition of growth, migration and invasion via a dihomo-gamma linolenic acid peroxidation dependent mechanism. AB - BACKGROUND: Cyclooxygenase-2 (COX-2), the inducible COX form, is a bi-functional membrane-bound enzyme that typically metabolizes arachidonic acid (downstream omega-6 fatty acid) to form 2-series of prostaglandins known to be involved in cancer development. Overexpression of COX-2 has been found in a majority of breast carcinomas, and has also been associated with increased severity and the development of the metastasis. Our lab recently demonstrated that COX-2 can also metabolize dihomo-gamma-linolenic acid (DGLA, a precursor of omega-6 arachidonic acid) to produce an anti-cancer byproduct, 8-hydroxyoctanoic acid (8-HOA) that can inhibit growth and migration of colon and pancreatic cancer cells. We thus tested whether our strategy of knocking down delta-5-desaturase (D5D, the key enzyme that converts DGLA to arachidonic acid) in breast cancer cells overexpressing COX-2 can also be used to promote 8-HOA formation, thereby suppressing cancer growth, migration, and invasion. METHODS: SiRNA and shRNA transfection were used to knock down D5D expression in MDA-MB 231 and 4 T1 cells (human and mouse breast cancer cell lines expressing high COX-2, respectively). Colony formation assay, FITC Annexin V/PI double staining, wound healing and transwell assay were used to assess the effect of our strategy on inhibition of cancer growth, migration, and invasion. GC/MS was used to measure endogenous 8 HOA, and western blotting was performed to evaluate the altered key protein expressions upon the treatments. RESULTS: We demonstrated that D5D knockdown licenses DGLA to inhibit growth of breast cancer cells via promoting formation of 8-HOA that can inhibit histone deacetylase and activate cell apoptotic proteins, such as procaspase 9 and PARP. Our strategy can also significantly inhibit cancer migration and invasion, associated with altered expression of MMP-2/- 9, E cadherin, vimentin and snail. In addition, D5D knockdown and DGLA supplementation greatly enhanced the efficacy of 5-fluorouracil on breast cancer growth and migration. CONCLUSIONS: Consistent to our previous studies on colon and pancreatic cancer, here we demonstrate again that the high level of COX-2 in breast cancer cells can be capitalized on inhibiting cancer growth and migration. The outcome of this translational research could guide us to develop new anti cancer strategy and/or to improve current chemotherapy for breast cancer treatment. PMID- 29587669 TI - Ezrin and E-cadherin expression profile in cervical cytology: a prognostic marker for tumor progression in cervical cancer. AB - BACKGROUND: Cervical cancer (CC) is the fourth cause of mortality by neoplasia in women worldwide. The use of immunomarkers is an alternative tool to complement currently used algorithms for detection of cancer, and to improve selection of therapeutic schemes. Aberrant expression of Ezrin and E-cadherin play an important role in tumor invasion. In this study we analyzed Ezrin and E-cadherin expression in liquid-based cervical cytology samples, and evaluated their potential use as prognostic immunomarkers. METHODS: Immunocytochemical staining of Ezrin and E-cadherin was performed in cervical samples of 125 patients. The cytological or histological diagnostic was performed by Papanicolaou staining or H&E staining, respectively. HPV genotyping was determined using INNO-LIPA Genotyping Extra kit and the HPV physical status by in situ hybridization. Ezrin expression in HaCaT, HeLa and SiHa cell lines was determined by immunocytochemistry, immunofluorescence and Western blot. RESULTS: High Ezrin expression was observed in cervical cancer samples (70%), samples with multiple infection by HR-HPV (43%), and samples with integrated viral genome (47%). High Ezrin expression was associated with degree of SIL, viral genotype and physical status. In contrast, low E-cadherin expression was found in cervical cancer samples (95%), samples with multiple infection by HR-HPV/LR-HPV (87%) and integrated viral genome (72%). Low E-cadherin expression was associated with degree of SIL and viral genotype. Interestingly, Ezrin nuclear staining was associated with degree of SIL and viral genotype. High Ezrin expression, high percent of nuclear Ezrin and low E-cadherin expression behaved as risk factors for progression to HSIL and cervical cancer. CONCLUSIONS: Ezrin and E-cadherin expression profile in cervical cytology samples could be a potential prognostic marker, useful for identifying cervical lesions with a high-risk of progression to cervical cancer. PMID- 29587670 TI - To fast, or not to fast before chemotherapy, that is the question. AB - Fasting in disease prevention and treatment has recently become a popular topic, particularly in the context of oncology. Unfortunately, the growing attention paid by the media has created a background of speculations and ambiguous messages. The attitude towards the role of fasting in cancer patients should be very cautious, as the risk of malnutrition/sarcopenia and disinformation may be associated with this approach. Whether the results obtained by fasting in the cellular and animal models can be transferred to cancer patients is still to be ascertained. At the moment, more preclinical studies are required to determine in which cancers, at which stage, and in what combinations fasting, fasting mimicking diets or caloric restriction mimetics may prove effective. So, despite the "rumors" of marketing and media, nowadays fasting and calorie restriction around CT represent only a promising intuition, which requires proper efforts and time to be validated by evidence-based clinical data. PMID- 29587671 TI - Coexisting of bone marrow fibrosis, dysplasia and an X chromosomal abnormality in chronic neutrophilic leukemia with CSF3R mutation: a case report and literature review. AB - BACKGROUND: Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative neoplasm (MPN) with less than 40 cases of patients being reported or clinically suspected meeting with 2008 World Health Organization ("WHO") diagnostic criteria. The current diagnosis of CNL remains to exclude other diseases. Recently, a new biomarker of CSF3R mutations that is almost invariably present in CNL has been identified. There is no effective treatment for CNL, therefore prognosis of the disease is poor, but it may be attributed to the presence of both SETBP1 and CSF3R gene mutations. The presence or absence of CSF3R mutation did not affect survival, whereas a trend for shortened survival was observed among patients with SETBP1-mutation. CASE PRESENTATION: Here we report a 65-year old woman patient who presented with leukocytosis without sign of fever and tumors. Bone marrow aspirates showed a markedly hypercellular feature with 76% 92% myeloid and the dysplastic changes were found in about 7% of neutrophils cells. The bone marrow biopsy demonstrated marrow fibrosis with Gomori staining positive (+++~++++). Cytogenetic analysis showed 46,X,del (X) (q22). No molecular markers of BCR/ABL1 rearrangement (P210, P230, P190 and variably), JAK2V617F, FIP1L1-PDGFRA, TEL-PDGFRB, ZNF198-FGFR1 and SETBP1 mutations were identified, however, the CSF3R gene membrane proximal mutation (c.1853C > T/p.T618I sites) was detected by PCR techniques. The patient was diagnosed with CNL and died in about 2 months after disease diagnosis. CONCLUSION: In clinical course, the CNL concurrently with severe bone marrow fibrosis and dysplastic features as well as X chromosomal abnormality may predict a worsening prognosis regardless of SETBP1 mutation status. PMID- 29587672 TI - Characteristics of patients with depression initiating or switching antidepressant treatment: baseline analyses of the PERFORM cohort study. AB - BACKGROUND: Patients who require a switch in their antidepressant therapy may have different clinical profiles and treatment needs compared with patients initiating or maintaining a first-line antidepressant therapy. METHODS: The Prospective Epidemiological Research on Functioning Outcomes Related to Major depressive disorder (MDD) (PERFORM) study was a 2-year observational cohort study in outpatients with MDD in five European countries. Enrolled patients were either initiating or undergoing the first switch to an antidepressant monotherapy. Baseline data on patients' clinical status, functioning, productivity, quality of life and medical-resource use were compared in a cross-sectional baseline analysis. RESULTS: A total of 1402 patients were enrolled, of whom 1159 (82.7%) provided analysable baseline data. The majority (78.7%) of the analysable population were initiating antidepressant treatment and most (83.6%) were enrolled and followed up by general practitioners. Compared with patients initiating antidepressants, those switching antidepressants (21.3%) tended to have more severe depressive symptoms, greater anxiety, worse health-related quality of life, greater functional impairment, greater medical-resource use and had a different medical history. Limitations included an over-representation of switches due to lack of efficacy among patients who were switching treatment, as patients were selected based on presence of depressive symptoms. CONCLUSIONS: Patients with MDD who are switching treatment for the first time have a different profile and different depression-associated health needs compared with those initiating treatment. Therapeutic management should therefore be adapted for patients who switch. TRIAL REGISTRATION: ClinicalTrials.gov NCT01427439 ; Retrospectively registered 26 August 2011. PMID- 29587673 TI - A randomised controlled trial of the effectiveness of a breastfeeding training DVD on improving breastfeeding knowledge and confidence among healthcare professionals in China. AB - BACKGROUND: Despite almost all babies being breastfed initially, the exclusive breastfeeding rate at six months is less than 30% in China. Improving professionals' knowledge and practical skill is a key government strategy to increase breastfeeding rates. This study aimed to test the effectiveness of a breastfeeding DVD training method for clinicians on improving their knowledge and confidence in the breastfeeding support skills of teaching mothers Positioning and Attachment (P & A) and Hand Expression (HE). METHODS: A randomised controlled trial was conducted in three hospitals in Zhejiang province, China in 2014. Participants were recruited before their routine breastfeeding training course and randomly allocated to intervention group (IG) and control group (CG). The 15 min "Breastfeeding: Essential Support Skills DVD" was the intervention for IG and a vaginal delivery DVD was used for CG. All participants completed questionnaires of job information, knowledge and confidence in the two skills before (baseline) and immediately after viewing the DVD (post DVD). RESULTS: Out of 210 participants, 191 completed knowledge assessments before and after watching the DVD (IG n = 96, CG n = 95), with the response rate of 91.0%. At baseline, there are no significant differences in job variables, total knowledge scores and confident scores. The total knowledge score significantly increased post-DVD for IG (pre-DVD: M = 5.39, SD = 2.03; post-DVD: M = 7.74, SD = 1.71; t (95) = - 10.95, p < 0.01), but no significant change in total knowledge score for CG between pre- and post-DVD (pre-DVD: M = 5.67, SD = 1.70; post-DVD: M = 5.56, SD = 1.63; t (94) = 0.85). The total confidence scores were significantly higher post DVD than pre-DVD in IG (pre-DVD: M = 66.49, SD = 11.27; post- DVD: M = 71.81, SD = 9.33; t (68) = - 4.92, p < 0.01), but no significant difference was seen in CG between pre- and post-DVD total confidence scores (pre-DVD: M = 68.33, SD = 11.08; post-DVD: M = 68.35, SD = 11.40; t (65) = - 0.25). Personal and job variables did not mediate these effects. CONCLUSIONS: The breastfeeding training DVD improved professionals' knowledge and confidence of the two breastfeeding support skills. However, the effect on professionals' practice and on breastfeeding outcomes needs to be examined in the future. PMID- 29587674 TI - Androgen receptor in advanced breast cancer: is it useful to predict the efficacy of anti-estrogen therapy? AB - BACKGROUND: Androgen receptor (AR) is widely expressed in breast cancer (BC) but its role in estrogen receptor (ER)-positive tumors is still controversial. The AR/ER ratio has been reported to impact prognosis and response to antiestrogen endocrine therapy (ET). METHODS: We assessed whether AR in primary tumors and/or matched metastases is a predictor of efficacy of first-line ET in advanced BC. Patients who had received first-line ET (2002-2011) were recruited, while those given concomitant chemotherapy or trastuzumab or pretreated with > 2 lines of chemotherapy were excluded. ER, progesterone receptor (PgR), Ki67 and AR expression were assessed by immunohistochemistry, and HER2 mainly by fluorescent in-situ hybridization. Cut-offs of 1 and 10% immunostained cells were used to categorize AR expression. RESULTS: Among 102 evaluable patients, biomarkers were assessed in primary tumors in 70 cases and in metastases in 49, with 17 patients having both determinations. The overall concordance rate between primary tumors and metastases was 64.7% (95% CI 42%-87.4%) for AR status. AR status did not affect TTP significantly, whereas PgR and Ki67 status did. AR/PgR >=0.96 was associated with a significantly shorter TTP (HR = 1.65, 95% CI 1.05-2.61, p = 0.028). AR status in primary tumors or metastases was not associated with progressive disease (PD) as best response. In contrast, Ki67 >= 20% and PgR < 10% showed a statistically significant association with PD as best response. CONCLUSIONS: AR expression does not appear to be useful to predict the efficacy of ET in advanced BC, whereas Ki67 and PgR exert a greater impact on its efficacy. PMID- 29587675 TI - Expression of Reg IV and SOX9 and their correlation in human gastric cancer. AB - BACKGROUND: Reg IV is a member of the regenerating gene family and has been demonstrated to be overexpressed in gastric cancer. However, the functional mechanism of Reg IV in gastric cancer is still unclear. METHODS: Expression of Reg IV and SOX9 were investigated by immunohistochemistry (IHC) and real-time PCR, and the correlation between the expression of Reg IV and SOX9 was analyzed in gastric cancer tissues. Reg IV expression vectors and a siRNA of Reg IV and SOX9 were transfected into human gastric cancer cells and the protein and mRNA levels of Reg IV and SOX9 were investigated by western blot and real-time PCR. The invasion and migration ability of gastric cancer cells with overexpressed Reg IV and with gene silence of Reg IV and SOX9 were examined by transwell chambers and wound healing assay. RESULTS: The Reg IV and SOX9 protein expression levels were both significantly higher in gastric cancer tissues compared with adjacent tissues (p = 0.022, p = 0.003). Reg IV protein expression significantly correlated with tumor invasion depth (p < 0.001), but had no significant correlations with age, clinical stage or lymph node metastasis. SOX9 protein expression also had no significant correlations with age, clinical stage, tumor invasion depth or lymph node metastasis. Reg IV transcript expression demonstrated a significant correlation with invasion depth and lymph node metastasis (p = 0.005, p < 0.001) and no significant correlations with age, clinical stage, tumor tissue differentiation or tumor size. SOX9 transcript expression demonstrated a significant correlation with invasion depth and tumor tissue differentiation (p = 0.044, p = 0.007) and no significant correlations with age, clinical stage or tumor size. The Reg IV expression showed a positive correlation with the SOX9 expression (p < 0.000, p = 0.008). Overexpression of Reg IV could upregulate SOX9 expression and promote invasiveness and migration of tumor cells, and silencing of Reg IV could downregulate SOX9 and inhibit invasiveness and migration of tumor cells in MKN-45 and AGS cells. On the other hand, silencing of SOX9 could upregulate Reg IV protein expression. CONCLUSIONS: Our study demonstrated that Reg IV positively regulates the expression of SOX9 and is involved in tumor cell invasion and migration in gastric cancer. PMID- 29587676 TI - 'Whose Shoes?' Can an educational board game engage Ugandan men in pregnancy and childbirth? AB - BACKGROUND: Men can play a significant role in reducing maternal morbidity and mortality in low-income countries. Maternal health programmes are increasingly looking for innovative interventions to engage men to help improve health outcomes for pregnant women. Educational board games offer a unique approach to present health information where learning is reinforced through group discussions supporting peer-to-peer interactions. METHODS: A qualitative study with men from Uganda currently living in the UK on their views of an educational board game. Men were purposively sampled to play a board game and participate in a focus group discussion. The pilot study explored perceptions on whether a board game was relevant as a health promotional tool in maternal health prior to implementation in Uganda. RESULTS: The results of the pilot study were promising; participants reported the use of visual aids and messages were easy to understand and enhanced change in perspective. Men in this study were receptive on the use of board games as a health promotional tool and recommended its use in rural Uganda. CONCLUSIONS: This study provides preliminary data on the relevancy and efficacy of using board games in maternal health. Key messages from the focus group appeared to be that the board game is more than acceptable to fathers and that it needs to be adapted to the local context to make it suitable for men in rural Uganda. PMID- 29587677 TI - A phase I/Ib study of OTSGC-A24 combined peptide vaccine in advanced gastric cancer. AB - BACKGROUND: We conducted a phase I/Ib, open-label, single-arm trial to assess the safety, tolerability and optimal scheduling regimen of OTSGC-A24 cancer vaccine in patients with advanced gastric cancer. METHODS: Patients with advanced gastric cancer with HLA-A*24:02 haplotype were included in this study. OTSGC-A24 was administered at 1 mg in 3-weekly (3w), 2-weekly (2w), and weekly (1w) cohorts to evaluate the safety, immunological response and schedule. Based on the highest specific cytotoxic T lymphocyte (CTL) induction rate at 4 weeks, using the ELISPOT test, cohorts were expanded to define the optimal dosing schedule for OTSGC-A24. RESULTS: In this study, 24 advanced gastric cancer patients with HLA A*24:02 haplotype were enrolled and treated in 3 cohorts (3w cohort: 3; 2w cohort: 11 and 1w cohort: 10 patients). The most common adverse events were decreased appetite (29%), diarrhea (21%), myalgia (25%). The most common treatment-related adverse event was injection site erythema (25%). No dose limiting toxicities were observed in any cohort and OTSGC-A24 was well tolerated. Positive CTL responses after vaccination were observed in 15 patients (75%) at 4 weeks: 3w cohort (33%), 2w cohort (88%), 1w cohort (78%). At 12 weeks, 18 patients had responded (90%); 3w cohort (100%), 2w cohort (100%), 1w cohort (78%). The best radiological was stable disease (40%). Median progression free survival was 1.7 months (95% CI: 1.4 to 3.5) and median overall survival was 5.7 months (95% CI 3.8 to 8.6). CONCLUSIONS: OTSGC-A24 combined peptide cancer vaccine was well tolerated. Significant responses in CTL were observed and the recommended phase 2 dose is 1 mg OTSGC-A24 sub-cutaneous, every 2 weeks. Although no radiological response was observed, a respectable overall survival was achieved, consistent with other immunotherapy agents being investigated in gastric cancer. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01227772 , Date registered: 21 Oct 2010. PMID- 29587678 TI - A national cross-sectional study of adherence to timely mammography use in Malta. AB - BACKGROUND: Routine mammography improves survival. To achieve health benefits, women must attend breast screening regularly at recommended time intervals. Maltese women are routinely invited to undergo mammography at three-year intervals at an organized breast screening programme (MBSP) or can opt to attend a private clinic. Previous research shows that health beliefs, particularly perceived barriers, were the most significant predictors of uptake to the first MBSP invitation. Whether these beliefs and other factors are predictive of adherence with recommended time intervals for mammography at organized or private screening in Malta is unknown. For the first time, this paper explores the predictors for Maltese women screened within or exceeding the recommended three year frequency in organized or private screening in Malta. METHODS: Information was obtained from a cross-sectional survey of 404 women, aged 50 to 60 years at the time of their first MBSP invitation, where women's characteristics, knowledge, health beliefs and illness perceptions were compared. The main variable of interest was women's mammography attendance within a three-year interval (ADHERENT) or exceeding three years (NON-ADHERENT). Data were analysed using descriptive statistics, chi-square test, Mann Whitney test, Independent Samples t-test and Shapiro Wilk test. RESULTS: At the time of the survey, 80.2% (n = 324) had been screened within three years (ADHERENT), 5.9% (n = 24) had exceeded the three-year frequency (NON-ADHERENT) while 13.9% (n = 56) never had a mammogram. No significant associations were found between ADHERENT or NON ADHERENT women in relation to sociodemographic or health status variables (p > 0.05). Knowledge of screening frequency was significantly associated with women's mammography adherence (chi2 = 5.5, p = 0.020). Health beliefs were the strongest significant predictors to describe the variance between ADHERENT and NON-ADHERENT screeners. When Mann Whitney test and Independent Samples t-test were applied on mammography adherence, perceived barriers and cues to action were found to be the most important predictors (p = 0.000, p = 0.039 respectively). CONCLUSIONS: To increase routine and timely mammography practices, women who are non-adherent to recommended time frequency guidelines should be targeted, together with their health beliefs, predominantly perceived barriers and cues to action. PMID- 29587680 TI - A case of silicone oil adhered to the retinal surface via perfluorocarbon liquid. AB - BACKGROUND: Perfluorocarbon liquid (PFCL) is widely used as an intraoperative heavy tamponade to flatten the retina and is replaced with silicone oil (SO) at the end of the surgery. Due to the long tamponade period, the SO is known to remain attached to the retina at the time of removal, and is commonly termed "sticky oil". The aim of this present study was to report a case of SO stickily attached to the retina via PFCL without tamponade period. CASE PRESENTATION: A 39 year-old male was referred to our hospital due to decreased vision and visual field defect in his right eye. Upon examination, he was diagnosed with rhegmatogenous retinal detachment in that eye. For treatment, he underwent vitrectomy with the use of PFCL and SO. The direct exchange of PFCL with SO resulted in residual subretinal fluid, so we subsequently attempted to remove the SO. However, a SO bubble adhering to the PFCL was visible on the posterior pole. After aspiration of the PFCL beneath the sticky SO, the SO was easily separated and removed from the retina. CONCLUSIONS: Our findings show that SO can become tightly adhered to the retinal surface via PFCL during vitrectomy, and that the sticky SO can be safely removed via aspiration of the PFCL layer underneath the SO. PMID- 29587681 TI - Association between age factors and strategies for promoting participation in gastric and colorectal cancer screenings. AB - BACKGROUND: Despite the long history of cancer screening in Japan, the participation rates in gastric and colorectal cancer screenings have not increased. Strategies for improving the participation rates have been proposed, but differences in their effects among different age groups remain unclear. METHODS: The Japanese government conducted a national survey in all municipalities in Japan in 2010 to investigate whether the implementation of promotion strategies increased participation in cancer screening. We investigated the association between age factors and strategies for promoting participation in cancer screening based on this national survey. Multiple regression analysis with generalized linear model was performed using the participation rates in gastric and colorectal cancer screenings as dependent variables, and the following strategies for promoting participation as independent variables: 1) personal invitation letters, 2) household invitation letters, 3) home visits by community nurses, 4) screenings in medical offices, and 5) free cancer screening programs. RESULTS: One thousand six hundred thirty nine municipalities for gastric cancer screening and 1666 municipalities for colorectal cancer screening were selected for the analysis. In gastric and colorectal cancer screenings, the participation rates of individuals aged 60-69 years was higher than those of other age groups. Personal and household invitation letters were effective promotion strategies for all age groups, which encouraged even older people to participate in gastric and colorectal cancer screenings. Screening in medical offices and free screenings were not effective in all age groups. Home visits were effective, but their adoption was limited to small municipalities. CONCLUSIONS: To clarify whether promotion strategies can increase the participation rate in cancer screening among different age groups, 5 strategies were assessed on the basis of a national survey. Although personal and household invitation letters were effective strategies for promoting participation in cancer screening for all age groups, these strategies equally encouraged older people to participate in gastric and colorectal cancer screenings. If resource for sending invitation letters are limited, priority should be given to individuals who are in their 50s and 60s for gastric and colorectal cancer screening. PMID- 29587679 TI - Activated innate lymphoid cell populations accumulate in human tumour tissues. AB - BACKGROUND: Innate lymphoid cells (ILC) are part of a heterogeneous family of haematopoietic effector cells which lack re-arranged antigen-specific receptors. They promote host defense and contribute to tissue and metabolic homeostasis, wound healing and immune surveillance. Their role in human cancer immunity is less defined, and therefore we aimed to identify the frequency and phenotype of distinct ILC groups in various types of cancer. METHODS: Tissue samples and peripheral blood were collected from patients undergoing surgical resection of gastrointestinal and breast tumours. Single cell suspension of tumour tissue was immediately obtained following surgery using tumour dissociation. RESULTS: We observed significantly higher frequencies of ILC2 (p value: 0.04) in malignant breast cancer tissue and significantly higher frequencies of group 1 ILC (p value: 0.001) in malignant gastrointestinal tumours. Tumour infiltrating ILC were found to show an activated phenotype with higher expression of MHC-II, KLRG1, early activation marker CD69 and CD44. CONCLUSIONS: Activated innate lymphoid cells infiltrate tumours dependent on tumour type and location. PMID- 29587682 TI - Impact of a behaviorally-based weight loss intervention on parameters of insulin resistance in breast cancer survivors. AB - BACKGROUND: Breast cancer survivors with excess weight are more likely to have negative breast cancer outcomes. Biomarkers related to insulin resistance may help explain this negative association. Weight loss is associated with improvements in insulin sensitivity. Our goal was to identify the impact of a behaviorally based weight loss intervention on indices of insulin resistance. METHODS: Overweight, early stage breast cancer survivors who completed initial cancer therapy were enrolled in a 6 month behaviorally based weight loss intervention that included calorie reduction, exercise and behavior modification. Biomarkers related to insulin resistance were obtained at baseline and after the intervention. Results from participants who achieved >=5% weight loss were compared to those who lost less weight. RESULTS: Despite not having diabetes as a preexisting diagnosis prior to the study, 69% of all participants were considered to have pre-diabetes or diabetes at baseline based on American Diabetes Association definitions. Participants who achieved >=5% weight loss had significantly lower fasting insulin, AUC insulin, and insulin resistance as measured by HOMA-IR. Beta cell function decreased as anticipated when insulin resistance improved. Additionally, leptin levels declined. CONCLUSIONS: Breast cancer survivors who achieved >=5% weight loss demonstrated significant improvements in indices of insulin resistance. Despite an exclusion criteria of diabetes at the time of enrolment, a high proportion met criteria for pre diabetes or diabetes at baseline. Pre-diabetes appears to be under recognized in overweight breast cancer survivors. Behaviorally based weight loss interventions can result in weight loss and improvements in biomarkers related to breast cancer outcomes and additionally may decrease the chance of developing diabetes.

PMID- 29587683 TI - Shorter survival in adolescent and young adult patients, compared to adult patients, with stage IV colorectal cancer in Japan. AB - BACKGROUND: The incidence of colorectal cancer in adolescent and young adult patients is increasing. However, survival and clinical features of young patients, especially those with stage IV disease, relative to adult patients remain unclear. METHODS: This retrospective single-institution cohort study was conducted at a tertiary care cancer center. Subjects were 861 consecutive patients who were diagnosed with stage IV colorectal cancer at the age of 15 to 74 years and who were referred to the division of surgery or gastrointestinal oncology at the National Cancer Center Hospital from 1999 to 2013. Overall survival (OS) was investigated and clinicopathological variables were analyzed for prognostic significance. RESULTS: Of these, 66 (8%) were adolescent and young adult patients and 795 (92%) were adult patients. Median survival time was 13.6 months in adolescent and young adult patients and 22.4 months in adult patients, and 5-year OS rates were 17.3% and 20.3%, respectively, indicating significant worse prognosis of adolescent and young adult patients (p = 0.042). However, age itself was not an independent factor associated with prognosis by multivariate analysis. When compared with adult patients, adolescent and young adult patients consisted of higher proportion of the patients who did not undergo resection of primary tumor, which was an independent factor associated with poor prognosis in multivariate analysis. In patients who did not undergo resection (n = 349), OS of adolescent and young adult patients were significantly worse (p = 0.033). CONCLUSIONS: Prognoses were worse in adolescent and young adult patients with stage IV colorectal cancer compared to adult patients in Japan, due to a higher proportion of patients who did not undergo resection with more advanced and severe disease, but not due to age itself. PMID- 29587684 TI - Delphinidin induced protective autophagy via mTOR pathway suppression and AMPK pathway activation in HER-2 positive breast cancer cells. AB - BACKGROUND: We have previously demonstrated the anticancer effect of anthocyanins. In this study, we explored the biological activities of delphinidin, the most common of the anthocyanidin monomers, that were related to autophagy in HER-2 positive breast cancer MDA-MB-453 and BT474 cells. METHODS: The effects of various doses of delphinidin on the proliferation and apoptosis of MDA-MB-453 and BT474 cells were analysed. Autophagy was identified as a critical factor that influenced chemotherapy, and the autophagic mechanism in delphinidin treated cells was investigated. The autophagy inhibitors, 3-MA and BA1, were used to analyse the effects of autophagy inhibition. RESULTS: Delphinidin inhibited proliferation, promoted apoptosis, and induced autophagy in MDA-MB-453 and BT474 cells in a dose-dependent manner. The inhibition of autophagy enhanced the delphinidin-induced apoptosis and antiproliferative effect in both HER-2 positive breast cancer cells. In addition, delphinidin induced autophagy via suppression of the mTOR signalling pathway and activation of the AMPK signalling pathway in HER-2 positive breast cancer cells. CONCLUSIONS: Collectively, the results showed that delphinidin induced apoptosis and autophagy in HER-2 positive breast cancer cells and that autophagy was induced via the mTOR and AMPK signalling pathways. The suppression of autophagy promoted the anticancer effects of delphinidin. PMID- 29587685 TI - Quality of life of survivors of malignant pleural mesothelioma in Japan: a cross sectional study. AB - BACKGROUND: Previous studies have indicated that people with malignant pleural mesothelioma (MPM) have a poor quality of life (QOL); however, information about the QOL of people with MPM in Japan is anecdotal. The aims of this study were to investigate the QOL of survivors of MPM in Japan and to determine the factors that correlate with their QOL. METHODS: This was a cross sectional study. The included patients were those diagnosed with MPM in Japan. We created a self administered questionnaire consisting of 64 questions. The questionnaires were sent to hospitals and patient advocacy groups, distributed to the patients, completed, and sent back to the researchers by postal mail. QOL was assessed with the European Organization for Research and Treatment of Cancer 16 questionnaire (QLQ) and the short version of the core domains of the Comprehensive Quality of Life Outcome questionnaire (CoQoLo). RESULTS: In total, 133 questionnaires were collected. The QLQ assessments demonstrated that the survivors of MPM most frequently complained of fatigue, pain, sleep disturbances, and dyspnea. The symptom scales were acceptable, but the functional scales were significantly poorer for the patients with poor performance statuses (PSs). The short CoQoLo assessment was very unfavorable for 'Being free from physical pain.' Being a long term survivor and a survivor with a poor PS were significantly correlated with poor global health status. CONCLUSIONS: Survivors of MPM have impaired function, a variety of symptoms, and lower QOL. Survivors of MPM, even those in good physical condition, need broad support. PMID- 29587686 TI - Information-based cues at point of choice to change selection and consumption of food, alcohol and tobacco products: a systematic review. AB - BACKGROUND: Reducing harmful consumption of food, alcohol, and tobacco products would prevent many cancers, diabetes and cardiovascular disease. Placing information-based cues in the environments in which we select and consume these products has the potential to contribute to changing these behaviours. METHODS: In this review, information-based cues are defined as those which comprise any combination of words, symbols, numbers or pictures that convey information about a product or its use. We specifically exclude cues which are located on the products themselves. We conducted a systematic review of randomised, cluster- randomised, and non-randomised controlled trials to assess the impact of such cues on selection and consumption. Thirteen studies met the inclusion criteria, of which 12 targeted food (most commonly fruit and vegetables), one targeted alcohol sales, and none targeted tobacco products. RESULTS: Ten studies reported statistically significant effects on some or all of the targeted products, although studies were insufficiently homogenous to justify meta-analysis. Existing evidence suggests information-based cues can influence selection and consumption of food and alcohol products, although significant uncertainty remains. CONCLUSIONS: The current evidence base is limited both in quality and quantity, with relatively few, heterogeneous studies at unclear or high risk of bias. Additional, more rigorously conducted studies are warranted to better estimate the potential for these interventions to change selection and consumption of food, alcohol and tobacco products. TRIAL REGISTRATION: PROSPERO. 2016; CRD42016051884 . PMID- 29587687 TI - Above-versus below-elbow casting for conservative treatment of distal radius fractures: a randomized controlled trial and study protocol. AB - BACKGROUND: A variety of cast options are available for the non-surgical treatment of distal radius fractures (DRF) in adults. However, the literature is inconclusive regarding the need to immobilize the elbow joint after reduction in order to prevent rotation of the forearm in order to maintain the reduction of DRF. This study aimed to evaluate the best method of immobilization between above elbow (AE) and below-elbow (BE) cast groups at the end of six-month follow-up. METHODS: This is a randomized clinical trial with parallel groups and a blinded evaluator. There are two non-surgical interventions: AE and BE. Patients will be randomly assigned. A hundred twenty eight consecutive adult patients with acute (up to 7 days) displaced DRF of type A2, A3, C1, C2 or C3 by the Arbeitsgemeinschaft fur Osteosynthesefragen (AO) classification will be included. The primary outcome will be the maintenance of reduction by evaluation of radiographic parameters and Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH). Secondary outcomes include function measured by Patient Rated Wrist Evaluation (PRWE), pain measured by the Visual Analogue Scale (VAS), objective functional evaluation (goniometry and dynamometry) and rate of complications. Evaluations will be performed at 1, 2, 3, 4, 6, 8, 12 and 24 weeks. For the Student's t-test, a difference of 10 points in DASH score, with 95% confidence interval, a statistical power of 95%, and 20% sampling error. We consider an extra 10% for balancing follow up losses results in 64 patients per group. DISCUSSION: Results from this study protocol will help to define the need for elbow immobilization in maintenance of reduction, as well as functional performance of below elbow cast versus above elbow cast immobilization during the immobilization period.

PMID- 29587688 TI - Computer-assisted cognitive remediation therapy increases hippocampal volume in patients with schizophrenia: a randomized controlled trial. AB - BACKGROUND: Cognitive remediation therapy (CRT) effectively reduces neurocognitive impairment in patients with schizophrenia, but few studies have used structural neuroimaging methods to assess its neuroanatomical effects. We investigated these effects, as well as the association between changes in cortical volume and neurocognitive performance. METHOD: Between August 2013 and September 2016, we performed a randomized controlled study comprising a CRT group (16 individuals) and a treatment-as-usual (TAU) group (15 individuals) of patients with schizophrenia. CRT participants engaged in twice-weekly computer assisted CRT sessions and weekly group meetings for 12 weeks. T1-weighted magnetic resonance imaging was performed before and after the intervention period, and whole-brain voxel-based morphometric analysis was used to detect significant cortical gray matter volume changes. We also assessed the correlation between cortical volume changes and CRT-derived neurocognitive improvements. RESULTS: The CRT group exhibited significantly greater improvements than the TAU group in verbal fluency (P = 0.012) and global cognitive scores (P = 0.049). The CRT group also exhibited significantly greater increases in right hippocampal volume than the TAU group (P < 0.001). Changes in verbal fluency scores and right hippocampal volumes were positively correlated (r = 0.53, P = 0.001). CONCLUSION: We found that CRT significantly increased right hippocampal volumes and that these enhancements were positively correlated with changes in verbal fluency scores. Our results indicate that CRT induces cognitive improvement through hippocampal plasticity. TRIAL REGISTRATION: Registration number: UMIN000026146 , 2017/02/15, retrospectively registered. PMID- 29587689 TI - Complementary feeding practices and associated factors in Damot Weydie District, Welayta zone, South Ethiopia. AB - BACKGROUND: Each year, more than millions of under-five children die due to under nutrition, and many of these deaths are associated with inappropriate feeding practices. This study aimed to assess complementary feeding practices in Damot Weydie District, South Ethiopia. METHODS: A community-based cross-sectional study was conducted among four-hundred and one mothers who had children aged 6-23 months in Damot Weydie District. A pretested structured questionnaire was used to collect data using a face-to-face interview. Data were entered into Epi-Data version 3.1 and analysis was done by using Statistical Package for Social Sciences (SPSS) version 20. Multivariable logistic regressions were conducted to determine independent factors associated with complementary feeding practices. RESULTS: More than half (50.6%) of children were given complementary foods at six months of age. Only 8.5% of young children aged 6-23 months were fed with appropriate complementary foods. The proportion of mothers who reported that they know that a baby of 6-23 months old should be fed two or three times was only 75.8%. Government-employed mothers (adjusted odds ratio (AOR) = 0.14(0.04, 0.50) and mothers who attended postnatal care (AOR = 0.19(0.05, 0.70) were less likely to practice inappropriate complementary feeding. Mothers having children with birth intervals less than 35 months were more likely to practice inappropriate complementary feeding when compared to mothers of children with birth intervals greater than 35 months (AOR = 2.67 (1.22, 5.83). CONCLUSIONS: Considerable proportions of infants and young children were not appropriately fed with complementary foods as per WHO recommendations. Being a government employee mother, attending postnatal care and having a child with birth interval greater than 3 years were associated with appropriate complementary feeding. Therefore, it is important to encourage postnatal care utilization and incorporate complementary feeding advice during postnatal visits. It is critical to raise the awareness of the community about optimal complementary feeding practices with special attention to unemployed and less educated mothers. Additionally, inter sectoral collaboration should be strengthened to increase the variety of food groups available. PMID- 29587690 TI - Evaluation of an interaction-skills training for reducing the burden of family caregivers of patients with severe mental illness: a pre-posttest design. AB - BACKGROUND: Family members who care for patients with severe mental illness experience emotional distress and report a higher incidence of mental illness than those in the general population. They report feeling inadequately prepared to provide the necessary practical and emotional support for these patients. The MAT training, an Interaction-Skills Training program (IST) for caregivers, was developed to meet those needs. This study used a single-arm pretest-posttest design to examine the impact of the training on caregivers' sense of competence (self-efficacy) and burden. METHODS: One hundred family caregivers recruited from three mental health institutions participated in the training. Burden was assessed using the Involvement Evaluation Questionnaire, and self-efficacy using the Self-Efficacy Questionnaire. Analysis of variance with repeated measures was used to investigate whether participation in the training changed the level of family caregivers' burden and self-efficacy. Pearson's correlation was used to examine the relationships between self-efficacy and burden. RESULTS: Our results indicate that, after the training, self-efficacy increased significantly over time (p < 0.001) and that burden decreased significantly (p < 0.001). However, the results could not demonstrate the expected association between an increase of self-efficacy and decrease of burden. Caregivers expressed high appreciation for the training. CONCLUSIONS: After following the IST program, family caregivers of patients with severe mental illness experienced a greater sense of competence and a significant decrease in burden. The training was greatly appreciated and satisfied caregivers' need to acquire the skills required in complex caregiving situations.

PMID- 29587691 TI - Trends in unprotected intercourse among heterosexual men before and after brothel ban in Siem Reap, Cambodia: a serial cross-sectional study (2003-2012). AB - BACKGROUND: Following Cambodia's implementation of the 100% condom use program with enforcement of condom use and STI treatment services for sex workers in 2001, sexually transmitted infection and HIV declined markedly. In 2008, Cambodia implemented a law to ban brothel-based sex work. We reported trends in unprotected vaginal intercourse with sex workers among heterosexual men buying sex before (2003-2008) and after (2009-2012) the brothel ban in Cambodia. We also determined the association of brothel ban with these men's reports of unprotected intercourse with sex workers. METHODS: In this serial cross-sectional study, we collected yearly behavioural data on random cross-sectional samples of heterosexual men buying sex who attended the only government health centre in Siem Reap for voluntary confidential counselling and testing (VCCT) between 2003 and 2012. We used multivariable Poisson regression analysis on the 10-year data of 976 men to obtain the adjusted prevalence ratio (aPR) of unprotected intercourse in the last 6 months by brothel closure. RESULTS: Men buying sex from non-brothel-based sex workers increased almost 3-fold from 17% in 2007-2008 before brothel closure to 55% in 2011-2012 after brothel closure (p < 0.001). Unprotected intercourse with sex workers in the last week increased significantly from 37% (2003-2004) before brothel closure to 65% (2011-2012) after brothel closure. This increase corresponded closely with the increase in self-reported unprotected intercourse from 35% to 61% by the sex workers (n = 1805) attending the same clinic for VCCT. Brothel closure was associated with an increased risk (aPR: 1.65; 95% CI: 1.40-1.94) of unprotected intercourse with sex workers. HIV prevalence in the heterosexual men declined significantly from 26% in 2003-2004 to 4.8% in 2007-2008 and 0 case in 2009-2010 before increasing to 5.6% in 2011 2012. CONCLUSION: Our findings suggest that the brothel ban had led to an increase in unprotected intercourse with all sex workers for men buying sex. This effect could be attributed to reduced condom access, a consequence of the lack of feasibility to implement the 100% condom use program following the brothel ban. The ban on brothels in Cambodia should be reviewed. PMID- 29587692 TI - Food safety labelling of chicken to prevent campylobacteriosis: consumer expectations and current practices. AB - BACKGROUND: Campylobacter is the leading cause of bacterial gastroenteritis worldwide, and contaminated chicken is a significant vehicle for spread of the disease. This study aimed to assess consumers' knowledge of safe chicken handling practices and whether their expectations for food safety labelling of chicken are met, as a strategy to prevent campylobacteriosis. METHODS: We conducted a cross sectional survey of 401 shoppers at supermarkets and butcheries in Wellington, New Zealand, and a systematic assessment of content and display features of chicken labels. RESULTS: While 89% of participants bought, prepared or cooked chicken, only 15% knew that most (60-90%) fresh chicken in New Zealand is contaminated by Campylobacter. Safety and correct preparation information on chicken labels, was rated 'very necessary' or 'essential' by the majority of respondents. Supermarket chicken labels scored poorly for the quality of their food safety information with an average of 1.7/5 (95% CI, 1.4-2.1) for content and 1.8/5 (95% CI, 1.6-2.0) for display. CONCLUSIONS: Most consumers are unaware of the level of Campylobacter contamination on fresh chicken and there is a significant but unmet consumer demand for information on safe chicken preparation on labels. Labels on fresh chicken products are a potentially valuable but underused tool for campylobacteriosis prevention in New Zealand. PMID- 29587693 TI - A case of allergic bronchopulmonary aspergillosis successfully treated with mepolizumab. AB - BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) is an allergic pulmonary disease comprising a complex hypersensitivity reaction to Aspergillus fumigatus. Clinical features of ABPA are wheezing, mucoid impaction, and pulmonary infiltrates. Oral corticosteroids and anti-fungal agents are standard therapy for ABPA, but long-term use of systemic corticosteroids often causes serious side effects. CASE PRESENTATION: A 64-year-old woman was diagnosed with ABPA based on a history of bronchial asthma (from 40 years of age), elevated total IgE, the presence of serum precipitating antibodies and elevated specific IgE antibody to A. fumigatus, and pulmonary infiltration. Bronchoscopy showed eosinophilic mucoid impaction. Systemic corticosteroid therapy was initiated, and her symptoms disappeared. Peripheral eosinophilia and pulmonary infiltration recurred five months after cessation of corticosteroid treatment. Systemic corticosteroids were re-initiated and itraconazole was added as an anti-fungal agent. The patient was free of corticosteroids, aside from treatment with a short course of systemic corticosteroids for asthma exacerbation, and clinically stable with itraconazole and asthma treatments for 3 years. In 2017, she experienced significant deterioration. Laboratory examination revealed marked eosinophilia (3017/MUL) and a chest computed tomography (CT) scan demonstrated pulmonary infiltration in the left upper lobe and mucoid impaction in both lower lobes. The patient was treated with high-dose inhaled corticosteroid/long-acting beta agonist, a long-acting muscarinic antagonist, a leukotriene receptor antagonist, and theophylline; spirometry revealed a forced expiratory volume in 1 s (FEV1) of 1.01 L. An uncontrolled asthma state was indicated by an Asthma Control Test (ACT) score of 18. Mepolizumab, 100 mg every 4 weeks, was initiated for the treatment of severe bronchial asthma with ABPA exacerbation. Bronchial asthma symptoms dramatically improved, and ACT score increased to 24, by 4 weeks after mepolizumab treatment. Peripheral eosinophil count decreased to 174/MUL. Spirometry revealed improvement of lung function (FEV1: 1.28 L). A chest CT scan demonstrated the disappearance of pulmonary infiltration and mucoid impaction. CONCLUSIONS: To our knowledge, this is the first case of ABPA to be treated with mepolizumab. Dramatic improvements were observed in symptoms, lung function, peripheral eosinophil counts, and chest images. Mepolizumab could serve as an alternative treatment with the potential to provide a systemic corticosteroid sparing effect. PMID- 29587694 TI - Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior. AB - BACKGROUND: Self-report questionnaires are a valuable method of physical activity measurement in public health research; however, accuracy is often lacking. The purpose of this study is to improve the validity of the Global Physical Activity Questionnaire by calibrating it to 7 days of accelerometer measured physical activity and sedentary behavior. METHODS: Participants (n = 108) wore an ActiGraph GT9X Link on their non-dominant wrist for 7 days. Following the accelerometer wear period, participants completed a telephone Global Physical Activity Questionnaire with a research assistant. Data were split into training and testing samples, and multivariable linear regression models built using functions of the GPAQ self-report data to predict ActiGraph measured physical activity and sedentary behavior. Models were evaluated with the testing sample and an independent validation sample (n = 120) using Mean Squared Prediction Errors. RESULTS: The prediction models utilized sedentary behavior, and moderate- and vigorous-intensity physical activity self-reported scores from the questionnaire, and participant age. Transformations of each variable, as well as break point analysis were considered. Prediction errors were reduced by 77.7 80.6% for sedentary behavior and 61.3-98.6% for physical activity by using the multivariable linear regression models over raw questionnaire scores. CONCLUSIONS: This research demonstrates the utility of calibrating self-report questionnaire data to objective measures to improve estimates of physical activity and sedentary behavior. It provides an understanding of the divide between objective and subjective measures, and provides a means to utilize the two methods as a unified measure. PMID- 29587695 TI - Comparison between absorbable pins and mini-screw fixations for the treatment of radial head fractures Mason type II-III. AB - BACKGROUND: The treatment of comminuted radial head fractures can include prosthetic replacement or open reduction and internal fixation. The purpose of this study is to evaluate the results of two different internal fixation systems for Mason type II-III radial head fractures. METHODS: Between 2005 and 2015, 82 patients were treated using pins and 65 patients by mini-screws. The follow-up protocol included: a clinical evaluation 15 days after surgery, and clinical and radiographic evaluations performed at 30 and 60 day intervals, unless any complications were reported by the patient. Over a period of at least 12-months of follow-up, patients were checked and interviewed. Clinical examinations included elbow range of motion (ROM), arm, shoulder and hand Disabilities, (DASH), and the Mayo Elbow Performance Score (MEPS). RESULTS: Sixty-one subjects who had been treated with mini-screws were clinically reviewed at a mean 47.3 +/- 35.8 month of follow-up; all patients who had been treated using absorbable pins were evaluated at a mean 82.5 +/- 20.6 month of follow-up. No significant statistically differences were observed between the two groups in the mean ROM, DASH, and MEPS scores. Residual pain was reported in 15.8%of the patients treated by pins and 9.2% patients treated by mini-screws. Secondary displacement of fracture fragments was observed in 8.5% patients treated by pins and 1.6% using mini-screws. CONCLUSIONS: Both absorbable pins and mini-screws provided adequate strength and rigidity, allowing good clinical and functional scores at a mid-term follow-up. However, a higher rate of secondary displacement of the fracture fragments was reported among subjects who had been treated using absorbable pins. PMID- 29587696 TI - Does leaving an abusive partner lead to a decline in victimization? AB - BACKGROUND: This paper investigates gender differences in persistence of intimate partner violence (IPV), for those remaining or leaving an abusive relationship. We followed a sample of males and females to examine whether leaving an abusive partner may alter the continuity of victimization. METHODS: Data were taken from the 21 and 30-year follow-ups of the Mater Hospital and University of Queensland Study of Pregnancy (MUSP) in Australia. A cohort of 1265 respondents, including 874 females and 391 males, completed a 21-item version of the Composite Abuse Scale. RESULTS: We found proportionally similar rates of IPV victimization for males and females at both the 21 and 30 year follow-ups. Females who reported they had an abusive partner at the 21 year follow-up were more likely to subsequently change their partner than did males. Harassment and then emotional abuse appeared to have a stronger association for females leaving a partner. For males, a reported history of IPV was not significantly associated with leaving the partner. There was no significant association between leaving (or not) a previous abusive relationship and later victimization, either for male or female respondents. CONCLUSION: Changing a partner does not interrupt the continuity of victimization either for male or female respondents, and previous IPV victimization remained a determining factor of re-abuse, despite re-partnering. PMID- 29587697 TI - Association between skirt size and chronic liver disease in post-menopausal women: a prospective cohort study within the United Kingdom Trial of Ovarian Cancer Screening (UKCTOCS). AB - BACKGROUND: We investigated the association between self-reported skirt size (SS) and change in SS, and incidence of chronic liver disease (CLD) in a prospective cohort study of women recruited to the UKCTOCS trial. METHODS: Women recruited to UKCTOCS in England without documented CLD self-reported their current UK SS during trial participation and were asked to recall their SS when aged in 20s (via completion of a questionnaire 3-5 years after recruitment). Participants were followed up via electronic health record linkage and hazard ratios (HR) calculated for incident liver-related events (LRE). RESULTS: Three hundred twenty two (0.3%) of 94,124 women experienced a first LRE. Compared to SS <= 16, rates of LRE were higher in the SS >= 18 groups (both when aged in 20s and at questionnaire completion). Event rates were higher if there was no change in SS or an increase in SS, compared to a decrease in SS. In the models adjusted for potential confounders, HRs for LRE were higher in the groups of women reporting SS >= 18 both when aged in 20s (HR = 1.39 (95% CI; 0.87-2.23)) and at questionnaire completion (HR = 1.37 (95% CI; 1.07-1.75)). Compared to a decrease in SS, HRs were higher in the no change (HR = 1.78 (95% CI; 0.95-3.34)) and increase (HR = 1.80 (95% CI; 1.01-3.21)) groups. CONCLUSION: CLD is associated with high SS and an increase in SS over time. These data suggest SS can be used in simple public health messages about communicating the risk of liver disease. TRIAL REGISTRATION: UKCTOCS is registered as an International Standard Randomised Controlled Trial, number ISRCTN22488978 . Registered 06/04/2000. PMID- 29587698 TI - A hybrid type I randomized effectiveness-implementation trial of patient navigation to improve access to services for children with autism spectrum disorder. AB - BACKGROUND: Significant racial, ethnic, and socioeconomic disparities exist in access to evidence-based treatment services for children with autism spectrum disorder (ASD). Patient Navigation (PN) is a theory-based care management strategy designed to reduce disparities in access to care. The purpose of this study is to test the effectiveness of PN a strategy to reduce disparities in access to evidence-based services for vulnerable children with ASD, as well as to explore factors that impact implementation. METHODS: This study uses a hybrid type I randomized effectiveness/implementation design to test effectiveness and collect data on implementation concurrently. It is a two-arm comparative effectiveness trial with a target of 125 participants per arm. Participants are families of children age 15-27 months who receive a positive screen for ASD at a primary care visit at urban clinics in Massachusetts (n = 6 clinics), Connecticut (n = 1), and Pennsylvania (n = 2). The trial measures diagnostic interval (number of days from positive screen to diagnostic determination) and time to receipt of evidence-based ASD services/recommended services (number of days from date of diagnosis to receipt of services) in those with PN compared to and activated control -Conventional Care Management - which is similar to care management received in a high quality medical home. At the same time, a mixed-method implementation evaluation is being carried out. DISCUSSION: This study will examine the effectiveness of PN to reduce the time to and receipt of evidence based services for vulnerable children with ASD, as well as factors that influence implementation. Findings will tell us both if PN is an effective approach for improving access to evidence-based care for children with ASD, and inform future strategies for dissemination.

PMID- 29587699 TI - Use of intervention mapping to adapt a health behavior change intervention for endometrial cancer survivors: the shape-up following cancer treatment program. AB - BACKGROUND: About 80% of endometrial cancer survivors (ECS) are overweight or obese and have sedentary behaviors. Lifestyle behavior interventions are promising for improving dietary and physical activity behaviors, but the constructs associated with their effectiveness are often inadequately reported. The aim of this study was to systematically adapt an evidence-based behavior change program to improve healthy lifestyle behaviors in ECS. METHODS: Following a review of the literature, focus groups and interviews were conducted with ECS (n = 16). An intervention mapping protocol was used for the program adaptation, which consisted of six steps: a needs assessment, formulation of matrices of change objectives, selection of theoretical methods and practical applications, program production, adoption and implementation planning, and evaluation planning. Social Cognitive Theory and Control Theory guided the adaptation of the intervention. RESULTS: The process consisted of eight 90-min group sessions focusing on shaping outcome expectations, knowledge, self-efficacy, and goals about healthy eating and physical activity. The adapted performance objectives included establishment of regular eating, balanced diet, and portion sizes, reduction in sedentary behaviors, increase in lifestyle and organized activities, formulation of a discrepancy-reducing feedback loop for all above behaviors, and trigger management. Information on managing fatigue and bowel issues unique to ECS were added. CONCLUSIONS: Systematic intervention mapping provided a framework to design a cancer survivor-centered lifestyle intervention. ECS welcomed the intervention and provided essential feedback for its adaptation. The program has been evaluated through a randomized controlled trial. PMID- 29587700 TI - Serum (1->3)-beta-D-glucan and galactomannan levels in patients with cystic fibrosis: a retrospective cohort study. AB - BACKGROUND: Aspergillus fumigatus is frequently encountered in sputum samples of patients with cystic fibrosis (CF), which traditionally has been interpreted as saprophytic airway colonization. However, this mere bystander role has been challenged by recent data. There is now evidence that Aspergillus fumigatus accelerates the decline of pulmonary function. (1->3)-beta-D-glucan (BDG) and galactomannan (GM) are highly sensitive fungal biomarkers that are used to diagnose invasive fungal disease. However, their diagnostic value in CF patients is largely unknown. METHODS: We conducted a retrospective cohort study on 104 CF patients to determine whether serum BDG and GM levels correlate with parameters such as Aspergillus-positive sputum cultures and lung function. RESULTS: Aspergillus fumigatus was persistently detected in 22 of the 104 CF patients (21%). Mean serum BDG and GM levels in the Aspergillus-positive patients were significantly higher than in those without persistent Aspergillus detection (89 versus 40 pg/ml [p = 0.022] and 0.30 versus 0.15 ODI [p = 0.013], respectively). 27 and 7 patients had elevated BDG (>= 60 pg/ml) or GM levels (> 0.5 ODI), respectivly. BDG and GM levels showed a significant correlation (p = 0.004). Patients with increased serum concentrations of BDG were more frequently Aspergillus-positive (40.7 versus 14.3%, p = 0.004) and had a significantly lower forced expiratory volume in one second (FEV1) than patients with a normal BDG (61.6 versus 77.1%, p = 0.007). In the multivariate analysis, BDG but not GM or the growth of A. fumigatus, proved to be an independent predictor for the FEV1. CONCLUSIONS: CF patients with persistent Aspergillus detection have elevated BDG and GM levels which ranged between healthy and invasively infected patients. Serum BDG may be superior to GM and fungal culture in predicting an impaired lung function in CF patients. PMID- 29587701 TI - The application of system dynamics modelling to environmental health decision making and policy - a scoping review. AB - BACKGROUND: Policy and decision-making processes are routinely challenged by the complex and dynamic nature of environmental health problems. System dynamics modelling has demonstrated considerable value across a number of different fields to help decision-makers understand and predict the dynamic behaviour of complex systems in support the development of effective policy actions. In this scoping review we investigate if, and in what contexts, system dynamics modelling is being used to inform policy or decision-making processes related to environmental health. METHODS: Four electronic databases and the grey literature were systematically searched to identify studies that intersect the areas environmental health, system dynamics modelling, and decision-making. Studies identified in the initial screening were further screened for their contextual, methodological and application-related relevancy. Studies deemed 'relevant' or 'highly relevant' according to all three criteria were included in this review. Key themes related to the rationale, impact and limitation of using system dynamics in the context of environmental health decision-making and policy were analysed. RESULTS: We identified a limited number of relevant studies (n = 15), two-thirds of which were conducted between 2011 and 2016. The majority of applications occurred in non-health related sectors (n = 9) including transportation, public utilities, water, housing, food, agriculture, and urban and regional planning. Applications were primarily targeted at micro-level (local, community or grassroots) decision-making processes (n = 9), with macro level (national or international) decision-making to a lesser degree. There was significant heterogeneity in the stated rationales for using system dynamics and the intended impact of the system dynamics model on decision-making processes. A series of user-related, technical and application-related limitations and challenges were identified. None of the reported limitations or challenges appeared unique to the application of system dynamics within the context of environmental health problems, but rather to the use of system dynamics in general. CONCLUSIONS: This review reveals that while system dynamics modelling is increasingly being used to inform decision-making related to environmental health, applications are currently limited. Greater application of system dynamics within this context is needed before its benefits and limitations can be fully understood. PMID- 29587702 TI - Change in muscle volume after steroid therapy in patients with myositis assessed using cross-sectional computed tomography. AB - BACKGROUND: Steroid therapy, a key therapy for inflammatory, allergic, and immunological disorders, is often associated with steroid myopathy as one of the side effects. Steroid therapy is considered the first-line therapy for myositis; however, there have been no reports strictly comparing the muscle mass in patients with myositis before and after steroid therapy. Thus, it is currently unclear whether steroid therapy for such patients affects muscle volume in addition to muscle strength. We aimed to determine the change in muscle mass after steroid therapy via cross-sectional computed tomography (CT) in patients with myositis. METHODS: Data from seven patients with myositis and eight controls, who were all treated with high doses of steroids, were assessed before and after steroid therapy. Clinical factors in patients with myositis included serum muscle enzyme levels and muscular strength. The cross-sectional area of skeletal muscle and the low muscle attenuation rate at the level of the caudal end of the third lumbar vertebra were obtained using CT and measured using an image analysis program for all patients. Data were subjected to statistical analysis using several well-established statistical tests. The Wilcoxon signed rank test was used for comparing paired data for each patient. The Mann-Whitney U test was used to compare sets of data sampled from two groups. The Spearman's rank correlation coefficient was used for determining the correlations between two variables. Statistical significance was set at p < 0.05. RESULTS: Muscular strength and serum muscle enzyme levels improved following steroid therapy in patients with myositis. In both groups, the cross-sectional areas of skeletal muscles decreased (myositis group: p = 0.0156; control group: p = 0.0391) and the low muscle attenuation rate tended to increase (myositis group: p = 0.0781; control group: p = 0.0547). In the myositis group, patients with chronic obstructive pulmonary disease showed a tendency toward muscle volume loss (p = 0.0571). CONCLUSION: In patients with myositis treated with steroid therapy, muscle mass decreased after steroid therapy suggesting that the improvement in muscle strength was due to factors other than a change in muscle volume. Our study suggests the importance of therapies that not only improve muscle mass but also improve the quality of muscle strength. PMID- 29587703 TI - Programming and supervision of resistance training leads to positive effects on strength and body composition: results from two randomised trials of community fitness programmes. AB - BACKGROUND: Many sedentary adults have high body fat along with low fitness, strength, and lean body mass (LBM) which are associated with poor health independently of body mass. Physical activity can aid in prevention, management, and treatment of numerous chronic conditions. The potential efficacy of resistance training (RT) in modifying risk factors for cardiovascular and metabolic disease is clear. However, RT is under researched in public health. We report community-based studies of RT in sedentary (Study 1), and overweight and pre-diabetic (Study 2) populations. METHODS: Study 1 - A semi randomised trial design (48-weeks): Participants choosing either a fitness centre approach, and randomised to structured-exercise (STRUC, n = 107), or free/unstructured gym use (FREE, n = 110), or not, and randomised to physical-activity-counselling (PAC, n = 71) or a measurement only comparator (CONT, n = 76). Study 2 - A randomised wait list controlled trial (12-weeks): Patients were randomly assigned to; traditional-supervised-exercise (STRUC, n = 30), physical-activity-counselling (PAC, n = 23), either combined (COMB, n = 39), or a wait-list comparator (CONT, n = 54). Outcomes for both were BF mass (kg), LBM (kg), BF percentage (%), and strength. RESULTS: Study 1: One-way ANCOVA revealed significant between group effects for BF% and LBM, but not for BF mass or strength. Post hoc paired comparisons revealed significantly greater change in LBM for the STRUC group compared with the CONT group. Within group changes using 95%CIs revealed significant changes only in the STRUC group for both BF% (- 4.1 to - 0.9%) and LBM (0.1 to 4.5 kg), and in FREE (8.2 to 28.5 kg) and STRUC (5.9 to 26.0 kg) for strength. Study 2: One-way ANCOVA did not reveal significant between group effects for strength, BF%, BF mass, or LBM. For strength, 95%CIs revealed significant within group changes for the STRUC (2.4 to 14.1 kg) and COMB (3.7 to 15.0 kg) groups. CONCLUSION: Strength increased in both studies across all RT treatments compared to controls, yet significant improvements in both strength and body-composition occurred only in programmed and/or supervised RT. As general increases in physical activity have limited impact upon body-composition, public health practitioners should structure interventions to include progressive RT. TRIAL REGISTRATION: Study 1: ISRCTN13024854 , retrospectively registered 20/02/2018. Study 2: ISRCTN13509468 , retrospectively registered 20/02/2018). PMID- 29587704 TI - Supporting change in chronic disease risk behaviours for people with a mental illness: a qualitative study of the experiences of family carers. AB - BACKGROUND: People with a mental illness experience greater chronic disease morbidity and mortality, and associated reduced life expectancy, compared to those without such an illness. A higher prevalence of chronic disease risk behaviours (inadequate nutrition, inadequate physical activity, tobacco smoking, and harmful alcohol consumption) is experienced by this population. Family carers have the potential to support change in such behaviours among those they care for with a mental illness. This study aimed to explore family carers': 1) experiences in addressing the chronic disease risk behaviours of their family members; 2) existing barriers to addressing such behaviours; and 3) perceptions of potential strategies to assist them to provide risk behaviour change support. METHODS: A qualitative study of four focus groups (n = 31), using a semi-structured interview schedule, was conducted with carers of people with a mental illness in New South Wales, Australia from January 2015 to February 2016. An inductive thematic analysis was employed to explore the experience of carers in addressing the chronic disease risk behaviours. RESULTS: Two main themes were identified in family carers' report of their experiences: firstly, that health behaviours were salient concerns for carers and that they were engaged in providing support, and secondly that they perceived a bidirectional relationship between health behaviours and mental well-being. Key barriers to addressing behaviours were: a need to attend to carers' own well-being; defensiveness on behalf of the family member; and not residing with their family member; with other behaviour-specific barriers also identified. Discussion around strategies which would assist carers in providing support for health risk behaviours identified a need for improved communication and collaboration between carers and health services accessed by their family members. CONCLUSIONS: Additional support from general and mental health services accessed by family members is desired to assist carers to address the barriers to providing behaviour change support. Carers have the potential to support and extend health service interventions aimed at improving the chronic disease risk behaviours of people with a mental illness but may require additional information, and collaboration from services. Further research is needed to explore these constructs in a large representative sample. PMID- 29587705 TI - An empirical exploration of female child marriage determinants in Indonesia. AB - BACKGROUND: Child marriage, defined as marriage before age 18, is associated with adverse human capital outcomes. The child marriage burden remains high among female adolescents in Indonesia, despite increasing socioeconomic development. Research on child marriage in Southeast Asia is scarce. No nationally representative studies thus far have examined determinants of child marriage in Indonesia through multivariate regression modeling. METHODS: We used data from the nationally representative 2012 Indonesian Demographic and Health Survey and the Adolescent Reproductive Health Survey to estimate determinants of child marriage and marital preferences. We ran multivariate models to estimate the association between demographic and socioeconomic characteristics and the following early marriage outcomes: 1) ever been married or cohabited, 2) married or cohabited before 18 years, 3) married or cohabited before 16 years, 4) self reported marital-age preferences and 5) attitudes approving female child marriage. RESULTS: Among the child marriage research sample (n = 6578, females aged 20-24 at time of survey), approximately 17% and 6% report being married before 18 and 16 years old respectively. Among the marital preferences research sample (n = 8779, unmarried females 15-24), the average respondent preferred marriage at approximately 26 years and 5% had attitudes approving child marriage. Education, wealth and media exposure have protective effects across marriage outcomes, while rural residence is a risk factor for the same. There are significant variations by region, indicating roles of religious, ethnic and other geographically diverse factors. CONCLUSION: This research fills a gap in understanding of child marriage determinants in Indonesia. There appears to be little support for child marriage among girls and young women, indicating an entry point for structural interventions that would lead to lasting change. Future research efforts should prioritize rigorous testing of gender transformative education and economic strengthening interventions, including cost effectiveness considerations to better understand how interventions and policies can be leveraged to deliver on ending child marriage in Indonesia and globally. PMID- 29587706 TI - TB epidemiology: where are the young women? Know your tuberculosis epidemic, know your response. AB - BACKGROUND: The global predominance of tuberculosis in men has received significant attention. However, epidemiological studies now demonstrate that there is an increased representation of young women with tuberculosis, especially in high HIV burden settings where young women bear a disproportionate burden of HIV. The role of the HIV epidemic, as well as changes in behavioural, biological, and structural risk factors are explored as potential explanations for the increasing burden of tuberculosis in young women. DISCUSSION: As young women are particularly vulnerable to HIV infection in sub-Saharan Africa, it is unsurprising that the TB epidemic in this setting has become increasingly feminised. This age-sex trend of TB in South Africa is similar to WHO estimates for other countries with a high HIV prevalence where there are more female than male cases notified up to the age of 25 years. The high prevalence of anaemia of chronic disease in young women with HIV is an additional potential reason for their increased TB risk. The widespread use of injectable medroxyprogesterone acetate contraception, which has been shown to possess selective glucocorticoid effect and oestrogen suppression, in young women may be an important emerging biological risk factor for tuberculosis in young women. Behavioural factors such as alcohol use and tobacco smoking patterns are further factors which may be responsible for the narrowing of the sex gap in TB epidemiology. In comparison to the significantly higher alcohol consumption rates in men globally, there is a narrowing gap in alcohol consumption between the sexes in South Africa with alarming rates of alcohol abuse in young women. There is a similar narrowing of the tobacco smoking gap between the sexes in South Africa, with increasing smoking prevalence in young women. CONCLUSION: With nearly 70% of all TB patients being co-infected with HIV in our setting, it is not surprising that the age and sex distribution of TB is increasingly resembling the distribution of HIV in this region of dual hyperendemicity. New TB service design must begin to reflect the presence of young women as a significant group burdened by the disease. PMID- 29587707 TI - School practices to promote social distancing in K-12 schools: review of influenza pandemic policies and practices. AB - BACKGROUND: During an evolving influenza pandemic, community mitigation strategies, such as social distancing, can slow down virus transmission in schools and surrounding communities. To date, research on school practices to promote social distancing in primary and secondary schools has focused on prolonged school closure, with little attention paid to the identification and feasibility of other more sustainable interventions. To develop a list and typology of school practices that have been proposed and/or implemented in an influenza pandemic and to uncover any barriers identified, lessons learned from their use, and documented impacts. METHODS: We conducted a review of the peer reviewed and grey literature on social distancing interventions in schools other than school closure. We also collected state government guidance documents directed to local education agencies or schools to assess state policies regarding social distancing. We collected standardized information from each document using an abstraction form and generated descriptive statistics on common plan elements. RESULTS: The document review revealed limited literature on school practices to promote social distancing, as well as limited incorporation of school practices to promote social distancing into state government guidance documents. Among the 38 states that had guidance documents that met inclusion criteria, fewer than half (42%) mentioned a single school practice to promote social distancing, and none provided any substantive detail about the policies or practices needed to enact them. The most frequently identified school practices were cancelling or postponing after-school activities, canceling classes or activities with a high rate of mixing/contact that occur within the school day, and reducing mixing during transport. CONCLUSION: Little information is available to schools to develop policies and procedures on social distancing. Additional research and guidance are needed to assess the feasibility and effectiveness of school practices to promote social distancing. PMID- 29587708 TI - Gender differences in occupational exposure to carcinogens among Italian workers. AB - BACKGROUND: Many carcinogenic chemicals are still used or produced in several economic sectors. The aim of this study is to investigate differences in occupational exposure patterns to carcinogens by gender in Italy. METHODS: Information about the most common carcinogens recorded in the Italian occupational exposures database (SIREP) for the period 1996-2015 was retrieved. Descriptive statistics were calculated for exposure-related variables (carcinogenic agent, occupational group, economic activity sector, and workforce size). The chi-square(chi2) test was used to verify differences between genders, and logistic regression analysis was performed to evaluate the association between gender and risk of having higher exposure levels, after adjusting for age. Concurrent exposures to multiple carcinogens were investigated using the two step cluster analysis. RESULTS: A total of 166,617 exposure measurements were selected for 40 different carcinogens. Exposed workers were only in a small proportion women (9%), and mostly aged 20-44 years (70%) in both genders. Women were more likely to be exposed than men to higher levels for several carcinogens even after correction for age at exposure, and the exposure level was significantly (p < 0.01) associated with occupation, economic sector and workforce size. The five main clusters of co-exposures identified in the entire dataset showed a differential distribution across economic sectors between genders. CONCLUSIONS: The exposures to occupational carcinogens have distinguishing characteristics in women, that are explained in part by work and job segregation. Because of the presence of high-exposed groups of female workers in many industrial sectors, further research and prevention efforts are recommended. PMID- 29587709 TI - Limitations of the S-TOFHLA in measuring poor numeracy: a cross-sectional study. AB - BACKGROUND: Although the Short Test of Functional Health Literacy in Adults (S TOFHLA) is widely used, misidentification of individuals with low health literacy (HL) in specific HL dimensions, like numeracy, is a concern. We examined the degree to which individuals scored as "adequate" HL on the S-TOFHLA would be considered as having low HL by two additional numerical measures. METHODS: English-speaking adults aged 45-75 years were recruited from a large, urban academic medical center and a community foodbank in the United States. Participants completed the S-TOFHLA, the Subjective Numeracy Scale (SNS), and the Graphical Literacy Measure (GL), an objective measure of a person's ability to interpret numeric information presented graphically. Established cut-points or a median split classified participants and having high and low numeracy. RESULTS: Participants (n = 187), on average were: aged 58 years; 63% female; 70% Black/African American; and 45% had a high school degree or less. Of those who scored "adequate" on the S-TOFHLA, 50% scored low on the SNS and 40% scored low on GL. Correlation between the S-TOFHLA and the SNS Total was moderate (r = 0.22, n = 186, p = 0.01), while correlation between the S-TOFHLA and the GL Total was large (r = 0.53, n = 187, p <= 0.01). CONCLUSIONS: Findings suggest that the S TOFHLA may not capture an individuals' HL in the dimension of numeracy. Efforts are needed to develop more encompassing and practical strategies for identifying those with low HL for use in research and clinical practice. TRIAL REGISTRATION: NCT02151032 (retrospectively registered: May 30, 2014). PMID- 29587710 TI - Partner age differences and associated sexual risk behaviours among adolescent girls and young women in a cash transfer programme for schooling in Malawi. AB - BACKGROUND: Age disparities in sexual relationships have been proposed as a key risk factor for HIV transmission in Sub-Saharan Africa, but evidence remains inconclusive. The SIHR study, a cluster randomised trial of a cash transfer programme in Malawi, found that young women in the intervention groups were less likely to have had a sexual partner aged 25 or older, and less likely to test positive for HIV and HSV-2 at follow-up compared to control groups. We examined the hypotheses that girls in the intervention groups had smaller age differences than control groups and that large age differences were associated with relationship-level HIV transmission risk factors: inconsistent condom use, sex frequency, and relationship duration. METHODS: We conducted an analysis of schoolgirls in the Schooling, Income, and Health Risk (SIHR) study aged 13-22 at baseline (n = 2907). We investigated the effects of study arm, trial stage and participant age on age differences in sexual relationships using a linear mixed effects model. Cumulative-link mixed-effects models were used to estimate the effect of relationship age difference on condom use and sex frequency, and a Cox proportional hazard model was used to estimate the effect of relationship age difference on relationship duration. We controlled for the girl's age, number of partners, study group and study round. RESULTS: Girls receiving cash transfers, on average, had smaller age differences in relationships compared to controls, though the estimated difference was not statistically significant (- 0.43 years; 95% CI: -1.03, 0.17). The older the participant was, the smaller her age differences (- 0.67 per 4-year increase in age; 95% CI: -0.99, - 0.35). Among controls, after the cash transfers had ended the average age difference was 0.82 years larger than during the intervention (95% CI: 0.43, 1.21), suggesting a possible indirect effect of the study on behaviour in the community as a whole. Across treatment groups, larger age differences in relationships were associated with lower levels of condom use, more frequent sex, and longer relationship durations. CONCLUSIONS: Cash-transfer programmes may prevent HIV transmission in part by encouraging young women to form age-similar relationships, which are characterised by increased condom use and reduced sex frequency. The benefits of these programmes may extend to those who are not directly receiving the cash. PMID- 29587711 TI - A review of paper-based advance care planning aids. AB - BACKGROUND: Advance care planning (ACP) aids can help prepare patients, family members, and physicians for in-the-moment medical decision-making. We wished to describe the content and approach of paper-based ACP aids in order to characterize existing aids and inform the development of a new ACP aid. METHODS: Paper-based ACP aids were identified through an environmental scan and screened for eligibility. ACP conceptual frameworks and data were gathered via stakeholder engagement and used to inform the coding framework that two investigators used to independently code each aid. A directed content analysis was conducted on these eligible aids. Aids were categorized through a deliberative process with an investigator abstracting general information for each aid. RESULTS: Fifteen aids met the eligibility criteria. They ranged in length from 6 to 78 pages with the average aid written at an eighth-grade reading level. The content analysis revealed that many aids encouraged choosing a surrogate decision maker and informed users about legal medical documents. Fewer than half of the aids facilitated patient clarification of values regarding quality of life issues. The authors identified and termed the following three categories of aids: informative; semi-action oriented; and action-oriented. It was often unclear whether patients contributed to the development or testing of the ACP aids reviewed. CONCLUSIONS: Most existing paper-based ACP aids address legal matters such as completing an advance directive. Only a minority elicited patient values and it was unclear whether any were developed in partnership with patients. Future development of ACP aids should account for patient preferences with a goal of supporting in-the-moment medical decision-making. PMID- 29587712 TI - The association between employment status and health among British adults with and without intellectual impairments: cross-sectional analyses of a cohort study. AB - BACKGROUND: There exists a well established link between employment status and health, with unemployment being associated with poorer health. Much less is known about the association between economic inactivity and health, especially among people with disabilities. Our aim is to determine whether the association between employment status and health is similar for adults with and adults without intellectual impairment. METHODS: Using nationally representative data from the 1970 British Cohort Study, we undertook a series of cross sectional analyses of the association between employment status and health (self-reported general health, mental health) among British adults with and without intellectual impairments at ages 26, 30, 34, 38 and 42. RESULTS: People with intellectual disability and borderline intellectual functioning had markedly lower employment rates and poorer health than other participants at all waves of data collection. When compared with participants in full-time employment the prevalence of poorer self rated health and mental health was higher among participants with and without intellectual impairment who were in either part-time employment or were economically inactive at all ages. When compared with participants in employment the prevalence of poorer self rated health and mental health was higher among participants with and without intellectual impairment who were in the economically inactive categories of unemployment, education/training and ill/disabled at all ages. Intellectual disability status appeared to moderate the strength of the relationship between economic activity and self-rated health and, to a much lesser extent, the relationship between economic activity and mental health. In all instances the moderation indicated a stronger association among participants without intellectual impairment. CONCLUSIONS: The results provide substantive evidence to suggest that the nature of the well-established association between employment and better health is similar for British adults with and without intellectual impairments. The results do, however, indicate that the magnitude of the effect involved differed. Further research is needed to identify mechanisms that may underlie this difference. PMID- 29587713 TI - Identifying complications requiring re-operation following primary hip or knee arthroplasty: a consecutive series of 98 patients. AB - BACKGROUND: The number of hip and knee arthroplasties completed is expected to double over the next decade. In public hospitals, regular post-arthroplasty orthopaedic review has commonly occurred for the duration of a patient's life, which requires substantial outpatient resources. However, there is limited evidence regarding the utility of these reviews for identifying complications. The current study investigated when and where complications requiring re operation were identified following primary hip or knee arthroplasty. METHODS: The medical records of all patients requiring re-operation for complications following primary hip arthroplasty (n = 48, 2004 to 2015) or knee primary arthroplasty (n = 50, 1998 to 2015) at a large regional health service were evaluated. Data were extracted by one of four investigators using a standardised electronic data extraction tool. Variables of interest included the health setting where the complication was initially identified, how long following the original operation the complication was identified and whether the complication was symptomatic. RESULTS: Routine post-arthroplasty orthopaedic appointments identified 15 (15.3%) complications requiring re-operation; all were identified in the first-year post-surgery. For each complication identified in the first year post-surgery, approximately 1000 orthopaedic outpatient appointments were required. After the first year, all complications were identified in Emergency Departments (n = 30, 30.6%), General Practice (n = 24, 24.5%) or non-routine orthopaedic outpatient appointments (n = 19, 19.4%). All patients with complications reported symptoms. CONCLUSIONS: Routine post-arthroplasty review appointments were an inefficient mechanism for identifying complications requiring re-operation more than one year following surgery. Public health services should consider assessing and redesigning post-arthroplasty review services to reduce the burden on patients and the demand for outpatient appointments. PMID- 29587714 TI - Varicella in Poland: economic burden in children 1-12 years of age in Poland, 2010-2015. AB - BACKGROUND: The safety and efficacy of live-attenuated varicella zoster virus (VZV) vaccines in preventing varicella and reducing associated morbidity and mortality in real-world have been previously shown. In Poland, VZV vaccination is only mandatory for certain high-risk individuals. Here, we have conducted an evaluation of the clinical and economic burden of varicella in Poland. METHODS: Multicenter, retrospective chart review of varicella inpatients and outpatients aged 1-12 years with a primary diagnosis between 2010 and 2015. Varicella-related outcomes included the incidence of complications, the proportion of patients reporting healthcare resource utilization (HCRU), and frequency of HCRU. Direct costs were derived from per patient resource use multiplied by unit costs, and indirect costs were calculated as loss of revenue of caregivers reporting work days missed. The overall annual cost of varicella in Poland was estimated based on the calculated direct and indirect costs per case and the estimated number of varicella cases. All costs are presented in 2015 Polish zloty (PLN) / Euros (?). RESULTS: A total of 150 children with varicella were included, of which 75 were outpatients and 75 were inpatients with a mean (+/- SD) age of 3.9 (+/-2.6) and 4.2 (+/-2.3) years, respectively. Complications were experienced by 14.7% of outpatients and 82.7% of inpatients, of which the most common were skin and soft tissue infections and dehydration. The rate of HCRU was as follows: over-the counter medications (80.0% outpatients, 81.3% inpatients), prescription medications (80.0% outpatients, 93.3% inpatients), tests/procedures (0.0% outpatients, 69.3% inpatients), and allied health professional consults (0.0% outpatients, 24.0% inpatients). Total (direct and indirect) cost per varicella case was 5013.3 PLN (? 1198.1) for inpatients and 1027.2 PLN (? 245.5) for outpatients, resulting in an estimated overall annual (2015) cost of varicella in Poland of 178,198,320 PLN (? 42,588,385) among children aged 1-15 years. CONCLUSIONS: Significant clinical and economic burden is associated with varicella in Poland. These results may be used to foster discussion related to the implications of implementing routine VZV vaccination in Poland. PMID- 29587715 TI - Comparative effectiveness of school-based caries prevention: a prospective cohort study. AB - BACKGROUND: Dental caries is the world's most prevalent childhood disease. School based caries prevention can reduce the risk of childhood caries by increasing access to care. However, the optimal mix of treatment services, intensity, and frequency of care is unknown. METHODS: Data were derived from two prospective cohorts of US children participating in two caries prevention programs with different treatment intensities. One program provided primary and secondary prevention (glass ionomer sealants and interim therapeutic restorations) and one primary prevention only (glass ionomer sealants), both given twice yearly in six month intervals. Primary study outcomes included untreated decay and the total observed caries experience. Analysis used generalized additive models to estimate nonlinear effects and trends over time. Results were compared to those estimated using generalized estimating equations and mixed-effects multilevel Poisson regression. RESULTS: Primary and secondary prevention combined did not significantly reduce total caries experience compared to primary prevention alone, but did reduce the risk of untreated decay on permanent dentition. Additionally, the rate of new caries experience was slower in the primary and secondary prevention group. Nonlinear trends for dental caries across both programs were statistically significant from zero (p < .001). CONCLUSION: Caries prevention consisting of primary and secondary prevention agents may be more effective than primary prevention alone in reducing the risk of tooth decay over time. Results suggest that the impact of caries prevention may not be constant over the medium- and long-term, suggesting reduced effectiveness with continued treatments. PMID- 29587716 TI - Matrix metalloproteinase-8 levels in oral samples as a biomarker for periodontitis in the Chinese population: an observational study. AB - BACKGROUND: Clinical evaluation of periodontal inflammation does not fully reflect the disease activity. Extensive studies have been conducted out on gingival crevicular fluid (GCF) components that might serve as potential diagnostic markers for periodontitis, among which matrix metalloproteinase-8 (MMP 8) has shown to be promising, but there were no studies for individuals in China. The aim of this study was to compare clinical diagnostic parameters and levels of active MMP-8 (aMMP-8) in GCF and oral rinse samples from the Chinese patients with varying degrees of periodontal inflammation. METHODS: GCF and oral rinse samples were obtained from 60 participants into two groups, a periodontitis group and a control group, specified by the presence and number of pocket depths or attachment loss. The aMMP-8 levels in GCF and oral rinse samples was quantified by ELISA using specific monoclonal antibodies. Logistic and linear regression models were employed for testing the correlation between aMMP-8 levels and periodontal condition, as well as diagnostic sensitivity and specificity. RESULTS: Periodontitis group (mean = 24.84 ng/ml) exhibited significantly higher aMMP-8 levels than control group in GCF (p < 0.001). The aMMP-8 levels in oral rinse samples ranged from 0.05 to 2.18 ng/ml, but differences were not statistically significant between the two groups (p > 0.1). Receiver operating characteristic curve analysis showed a highest threshold of 6.66, with a corresponding sensitivity and specificity of 0.8 and 0.9, respectively. CONCLUSIONS: Measuring aMMP-8 levels in GCF may have potentiality for complementary early diagnosis of periodontal disease and inflammation in the Chinese population. PMID- 29587717 TI - The prevalence of metabolic syndrome in patients receiving antipsychotics in Qatar: a cross sectional comparative study. AB - BACKGROUND: Metabolic abnormalities are common in patients maintained on antipsychotics. These abnormalities increase the risk of cardiovascular diseases and mortality in this population. The aim of this study is to assess the prevalence of metabolic syndrome (MetS) in subjects maintained on antipsychotics relative to controls in Qatar, and to assess the factors contributing to the development of MetS. METHODS: A cross sectional design was used to collect data and fasting blood samples from subjects maintained on antipsychotics for at least six months (n = 112) and from a control group (n = 114). The groups were compared in regard to prevalence of MetS, and multiple regression analysis was used to determine the risk factors in each group. RESULTS: The two groups (antipsychotics vs. control) were similar in regard to age (35.73 +/- 10.28 vs. 35.73 +/- 8.16 years) and gender ratio. The MetS was higher among the subjects on antipsychotics, but this difference did not reach statistical significance. Blood pressure (BP) was significantly higher in the antipsychotics group and BMI was the major risk factor to develop MetS in this group. CONCLUSIONS: The prevalence of MetS in both groups is high and mostly attributed to obesity and high BP. Public health interventions are needed to address this major health problem overall. Larger studies are needed to further assess the impact of antipsychotics and mental illness on the development of MetS. PMID- 29587718 TI - Triptorelin relieves lower urinary tract symptoms in Chinese advanced prostate cancer patients: a multicenter, non-interventional, prospective study. AB - BACKGROUND: Although triptorelin is increasingly used in China for biochemical castration, its effects on primary prostate cancer symptoms remain unclear. This study aimed to assess the prevalence of lower urinary tract symptoms (LUTS) in Chinese prostate cancer patients and the effectiveness of triptorelin on LUTS. METHODS: In this 48-week multicenter, non-interventional, prospective study, we enrolled patients with locally advanced or metastatic prostate cancer. Patients received triptorelin (15 mg) intramuscularly at baseline and at weeks 12, 24, and 36 with symptom assessment using the International Prostate Symptoms Score (IPSS). The primary endpoints were the prevalence of LUTS at baseline per IPSS categories and the percentage of patients with moderate to severe LUTS (IPSS > 7) at baseline, having at least a 3-point reduction of IPSS score at week 48. RESULTS: A total of 398 patients were included; 211 (53.0%) and 160 (40.2%) among them had severe and moderate LUTS, respectively. Of the patients with IPSS scores available at baseline and at week 48 (n = 213), 81.2% achieved a reduction in IPSS of at least 3 points. Of the patients with moderate to severe LUTS at baseline and IPSS scores available at baseline and at week 48 (n = 194), 86.6% achieved a total IPSS reduction of at least 3 points. CONCLUSIONS: The vast majority of Chinese patients with locally advanced or metastatic prostate cancer scheduled to receive triptorelin as part of their standard treatment have severe or moderate LUTS. Triptorelin therapy resulted in sustained improvement of LUTS in these patients. PMID- 29587719 TI - Nurse led home-based care for people with HIV/AIDS. AB - BACKGROUND: Home-based care is used in many countries to increase quality of life and limit hospital stay, particularly where public health services are overburdened. Home-based care objectives for HIV/AIDS can include medical care, delivery of antiretroviral treatment and psychosocial support. This review assesses the effects of home-based nursing on morbidity in people infected with HIV/AIDS. METHODS: The trials studied are in HIV positive adults and children, regardless of sex or setting and all randomised controlled. Home-based care provided by qualified nurses was compared with hospital or health-facility based treatment. The following electronic databases were searched from January 1980 to March 2015: AIDSearch, CINAHL, Cochrane Register of Controlled Trials, EMBASE, MEDLINE and PsycINFO/LIT, with an updated search in November 2016. Two authors independently screened titles and abstracts from the electronic search based on the study design, interventions and types of participant. For all selected abstracts, full text articles were obtained. The final study selection was determined with use of an eligibility form. Data extraction was performed independently from assessment of risk of bias. The results were analysed by narrative synthesis, in order to be able to obtain relevant effect measures plus 95% confidence intervals. RESULTS: Seven studies met the inclusion criteria. The trial size varied from 37 to 238 participants. Only one trial was conducted in children. Five studies were conducted in the USA and two in China. Four studies looked at home-based adherence support and the rest at providing home-based psychosocial support. Reported adherence to antiretroviral drugs improved with nurse-led home-based care but did not affect viral load. Psychiatric nurse support in those with existing mental health conditions improved mental health and depressive symptoms. Home-based psychological support impacted on HIV stigma, worry and physical functioning and in certain cases depressive symptoms. CONCLUSIONS: Nurse-led home-based interventions could help adherence to antiretroviral therapy and improve mental health. Further larger scale studies are needed, looking in more detail at improving medical care for HIV, especially related to screening and management of opportunistic infections and co morbidities. PMID- 29587720 TI - Spontaneous adrenocorticotropic hormone (ACTH) normalisation due to tumour regression induced by metyrapone in a patient with ectopic ACTH syndrome: case report and literature review. AB - BACKGROUND: Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is caused by tumours releasing ACTH. Ectopic ACTH-producing tumour regression is rarely induced using steroidogenesis inhibitors. We presented a case of EAS in which ACTH production by a lung tumour was reduced by metyrapone (MTP) and also reviewed previous cases of ectopic ACTH production suppressed via steroidogenesis inhibition. CASE PRESENTATION: A 71-year-old female with general fatigue, central obesity and impaired glucose tolerance was diagnosed with Cushing's syndrome due to elevated ACTH (192.9 pg/mL; normal range, 7.2-63.3 pg/mL), cortisol (73.1 MUg/dL; 6.4-21.0 MUg/dL) and 24-h urinary free cortisol (UFC) (6160 MUg/day; 11.2 80.3 MUg/day) levels. Chest computed tomography identified a solid 26.6 * 22.9 * 30.0 mm tumour with a cavity in the upper lobe of the left lung. There was no adrenal gland enlargement. Tumour markers were not significantly elevated; ACTH levels were not suppressed by 8-mg dexamethasone. A corticotropin-releasing hormone stimulation test revealed blunted ACTH response (basal ACTH, 204.6 pg/mL; highest ACTH level during the 120-min stimulation test, 214.0 pg/mL). She was diagnosed with EAS due to a lung lesion. MTP treatment was started to reduce cortisol production. ACTH levels and cortisol and UFC levels were normalised and the ACTH-producing lung tumour was ablated after MTP treatment. In several reported cases, plasma ACTH levels reduced during steroidogenesis inhibitor treatment for EAS. Among the 10 patients, three cases of pheochromocytoma, one of thymic carcinoid and one of islet cell carcinoma were reported. In four cases, the tumour was not detected. In our case, the pathology of the lung tumour was unknown because of lack of tumour cells in biopsy. The patients were treated with ketoconazole (KTZ) and/or MTP and exhibited ACTH and cortisol/UFC suppression, but tumour regression was observed only in our case. CONCLUSION: MTP and/or KTZ may reduce ACTH and cortisol production. The tumour spontaneously regressed after MTP treatment, indicating that MTP may reduce the tumour size without surgery. The mechanisms of therapeutic effects of steroidogenesis inhibitors and prognosis of spontaneous remission should be elucidated further via molecular biology studies. PMID- 29587721 TI - Older adults' readiness to engage with eHealth patient education and self-care resources: a cross-sectional survey. AB - BACKGROUND: This study examined access to digital technologies, skills and experience, and preferences for using web-based and other digital technologies to obtain health information and advice among older adults in a large health plan. A primary aim was to assess the extent to which digital divides by race/ethnicity and age group might affect the ability of a large percentage of seniors, and especially those in vulnerable groups, to engage with online health information and advice modalities (eHIA) and mobile health (mHealth) monitoring tools. METHODS: A mailed survey was conducted with age-sex stratified random samples of English-speaking non-Hispanic white, African-American/black (black), Hispanic/Latino (Latino), Filipino-American (Filipino), and Chinese-American (Chinese) Kaiser Permanente Northern California members who were aged 65-79 years. Respondent data were weighted to the study population for the cross sectional analyses. RESULTS: Older seniors and black, Latino, and Filipino seniors have less access to digital tools, less experience performing a variety of online tasks, and are less likely to believe that they would be capable of going online for health information and advice compared to younger and white Non Hispanic seniors. Consequently, they are also less likely to be interested in using eHIA modalities. CONCLUSIONS: The same subgroups of seniors that have previously been shown to have higher prevalence of chronic conditions and greater difficulties with healthcare access are also less likely to adopt use of eHIA and mHealth monitoring technologies. At the patient population level, this digital divide is important to take into account when planning health information and chronic disease management programs. At the individual patient level, to provide good patient-centered care, it is important for providers to assess rather than assume digital access, eHealth skills, and preferences prior to recommending use of web-based resources and mHealth tools. PMID- 29587722 TI - Personality traits and career choices among physicians in Finland: employment sector, clinical patient contact, specialty and change of specialty. AB - BACKGROUND: Personality influences an individual's adaptation to a specific job or organization. Little is known about personality trait differences between medical career and specialty choices after graduating from medical school when actually practicing different medical specialties. Moreover, whether personality traits contribute to important career choices such as choosing to work in the private or public sector or with clinical patient contact, as well as change of specialty, have remained largely unexplored. In a nationally representative sample of Finnish physicians (N = 2837) we examined how personality traits are associated with medical career choices after graduating from medical school, in terms of employment sector, patient contact, medical specialty and change of specialty. METHODS: Personality was assessed using the shortened version of the Big Five Inventory (S-BFI). An analysis of covariance with posthoc tests for pairwise comparisons was conducted, adjusted for gender and age with confounders (employment sector, clinical patient contact and medical specialty). RESULTS: Higher openness was associated with working in the private sector, specializing in psychiatry, changing specialty and not practicing with patients. Lower openness was associated with a high amount of patient contact and specializing in general practice as well as ophthalmology and otorhinolaryngology. Higher conscientiousness was associated with a high amount of patient contact and specializing in surgery and other internal medicine specialties. Lower conscientiousness was associated with specializing in psychiatry and hospital service specialties. Higher agreeableness was associated with working in the private sector and specializing in general practice and occupational health. Lower agreeableness and neuroticism were associated with specializing in surgery. Higher extraversion was associated with specializing in pediatrics and change of specialty. Lower extraversion was associated with not practicing with patients. CONCLUSIONS: The results showed distinctive personality traits to be associated with physicians' career and specialty choices after medical school independent of known confounding factors. Openness was the most consistent personality trait associated with physicians' career choices in terms of employment sector, amount of clinical patient contact, specialty choice and change of specialty. Personality-conscious medical career counseling and career guidance during and after medical education might enhance the person-job fit among physicians. PMID- 29587723 TI - Patient satisfaction and gender composition of physicians - a cross-sectional study of community health services in Hubei, China. AB - BACKGROUND: Patient satisfaction is associated with both individual (patients and health workers) and organizational (health facilities) characteristics. This study aimed to establish a link between patient satisfaction and gender composition of physicians in community health service (CHS) organizations. METHODS: Participants were selected through multistage stratified random sampling: 36 CHS centers were selected from six municipalities in Hubei, China. All physicians on duty and patients visiting the CHS during the study period (from April to October in 2015) were invited to participate in this study: 324 physicians and 865 patients completed a questionnaire survey. Multilevel linear regression analyses were performed to determine the associations of patient satisfaction (scored from 1 to 5) with patient characteristics (gender, age, education, income, medical expense, frequency of visits to the CHS) and organizational features of the CHS (sex ratio of physicians, and gender differences of physicians in education and job satisfaction). RESULTS: Older patients and those with a higher medical bill had a lower degree of satisfaction (p < 0.05). At the organizational level: a higher proportion of male physicians weakened the negative association between patient age and patient satisfaction (p < 0.05); a larger gap in university qualifications between male and female physicians exacerbated the negative association between patient age and patient satisfaction (p < 0.05). CONCLUSIONS: The gender composition of physicians in CHSs is associated with patient satisfaction in the Chinese context: a larger gap (in number and qualifications) between male and female physicians is associated with higher patient satisfaction. Further studies are needed to explore the cultural roots of such an association. PMID- 29587724 TI - Prevalence and correlates of depression and alcohol use disorder among adults attending primary health care services in Nepal: a cross sectional study. AB - BACKGROUND: Although depression and alcohol use disorder (AUD) are expected to be common among patients presenting to primary health care setting, there is limited research on prevalence of depression and AUD among people attending primary health care services in low-income countries. The aim of this study was to assess the prevalence of depression and AUD among adults attending primary care facilities in Nepal and explore factors associated with depression and AUD. METHODS: We conducted a population-based cross-sectional health facility survey with 1474 adults attending 10 primary healthcare facilities in Chitwan district, Nepal. The prevalence of depression and AUD was assessed with validated Nepali versions of the Patient Health Questionnaire (PHQ-9) and Alcohol Use Disorder Identification Test (AUDIT). RESULTS: 16.8% of the study sample (females 19.6% and males 11.3%) met the threshold for depression and 7.3% (males 19.8% and females 1.1%) for AUD. The rates of depression was higher among females (RR = 1.48, P = 0.009), whereas rates of AUD was lower among females (RR = 0.49, P = 0.000). Rates of depression and AUD varied based on education, caste/ethnicity, occupations and family income. CONCLUSIONS: In Nepal, one out of five women attending primary care services have depression and one out of five men have AUD. Primary care settings, therefore, are an important setting for detection and treatment initiation for these conditions. Given that "other" occupation is at increased risk for both conditions, it will be important to assure that treatments are feasible and effective for this high risk group. PMID- 29587725 TI - Associations between emotional intelligence, empathy and personality in Japanese medical students. AB - BACKGROUND: It is known that empathic communication is important for physicians to achieve higher patient satisfaction and health outcomes. Emotional intelligence (EI), empathy and personality in medical students predict students' individual disposition and their emotional and empathic perceptions. This study aimed to investigate: 1) The association between empathy, EI and personality, and 2) Gender differences in the association between empathy, EI and personality. METHOD: Participants were 357 1st year medical students from 2008 to 2011 at one medical school in Japan. Students completed self-report questionnaires comprising three validated instruments measuring EI: Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF), empathy: Jefferson Scale of Physician Empathy- student version (JSPE) and personality: NEO-Five-Factor Inventory (NEO FFI), which explores 5 dimensions of personality Neuroticism (N), Extraversion (E), Openness to experience (O), Agreeableness (A), and Conscientiousness (C). RESULTS: Pearson Correlations showed weak association between TEIQue-SF and JSPE. TEIQue-SF and NEO-FFI showed positive correlation for E and C, and strong negative correlation for N and weak positive correlation for A and O. Weak positive correlation between JSPE and the NEO-FFI were observed for E and A. Although effect sizes were small, N, A and empathy were significantly higher in females (unpaired t-test). However, hierarchical multiple-regression analysis when controlling for gender and personality showed no association between EI, empathy and gender. A, TEIQue-SF and N were found to make small contributions in respect of predictions for JSPE. Personality contributed significantly to the prediction of TEIQue-SF. N had the largest independent negative contribution (beta = - 0,38). CONCLUSION: In our study population of 1st year medical students, females had significantly higher N, A and empathy scores than males. Medical students' N score was strongly negatively associated with EI. Empathy was weakly associated with EI and A. However, when controlling gender and personality in regression analysis, gender did not affect EI and empathy, rather personality is the most important factor. Our findings indicate that N is a major factor that negatively affects EI. It is important to mitigate N using thoughtful training, taking into account students' personalities, to reduce N. In future studies, we will assess how communication trainings for students might enhance EI. PMID- 29587726 TI - Perceptions, experiences and expectations of Iraqi medical students. AB - BACKGROUND: The environment for medical education in Iraq has been difficult for many years. The 2003 invasion of Iraq accelerated a steady emigration of faculty and graduates. Kidnappings and deaths of doctors became commonplace. To understand current career plans, expectations and perceptions of medical students, three Baghdad medical schools were surveyed. METHODS: Written questionnaires were completed by 418 medical students variously in their 4th, 5th and 6th (final)years of training. We asked about perceptions of the quality of their medical education, the quality of health services in Iraq generally, and about deaths, injuries and migration of faculty, classmates and family. RESULTS: The average age of students was 22 years, with 59% women. Most students (90%) were originally from Baghdad. Although there were some positive responses, many students (59%) rated the overall quality of their medical education as fair or poor. Three-fourths of students believed the quality of hospital care in Iraq to be only fair or poor. A majority of students (57%) stated they were thinking frequently or all the time about leaving Iraq after graduation. Reasons given for leaving included the desire for further education, seeking a better lifestyle and fleeing conflict. Leading reasons for staying included the pull of friends and family, familiarity with the health system, and a sense of responsibility to the country. Nearly one in five (18%) students reported the death of a family member attributable to intentional violence, and 15% reported the violent death of a medical school classmate or faculty member since the 2003 invasion. Half the students reported at least one school faculty members had left Iraq because of the war. CONCLUSION: Medical students hold a mediocre view of the quality of their medical education and of Iraq's health system. Many of their faculty members have left the country. The majority of students may leave Iraq after graduation, afforded the opportunity. This poses a significant problem for staffing an already demoralized and stressed health system. Current circumstances suggest the situation will continue to deteriorate. PMID- 29587727 TI - Assessing youth-friendly sexual and reproductive health services: a systematic review. AB - BACKGROUND: Over the last quarter century, there has been an emergence of evidence-based research directed toward the development, implementation, and assessment of youth-friendly health services (YFHS) to improve the delivery of sexual and reproductive health services for young people. Despite these research efforts, evidence supporting the effectiveness of YFHS is limited, which may be attributed to a lack of consensus on how to define and measure youth-friendliness to track progress and evaluate outcomes. The purpose of this systematic review is to assess how youth-friendly sexual and reproductive health services are measured worldwide. METHODS: We conducted a systematic review of studies measuring youth friendly sexual and reproductive health services at health facilities published between January 2000 and June 2015 using PubMed, Web of Science, and POPLINE databases. Additional studies were identified by reviewing references of selected articles. Studies were screened to identify measurements and indicators that have been used to measure YFHS. RESULTS: Our review identified 20 studies from an initial search of more than 11,000 records, including six from high-income countries and 14 from low-and middle-income countries. The review identified 115 indicators used for measuring youth-friendly sexual and reproductive health services. Our review found a lack of consistency in the tools and indicators used to measure YFHS. The three most frequently assessed domains were accessibility, staff characteristics and competency, and confidentiality and privacy. The majority of the indicators were not specific to young people's needs and often reflected basic standards of care. CONCLUSIONS: This review shows the need for standardization and prioritization of indicators for the evaluation of YFHS. The results can be used to identify a core set of indicators that can be incorporated into a framework for assessing youth-friendly sexual and reproductive health services. There is a need to further distinguish between those variables that may have greatest impact on the use of services by young people, such as respect and privacy, those that impact the quality of services offered, and those that have limited relevance. Conducting more rigorous studies using a refined set of indicators is critical to measure and compare the impact and effectiveness of YFHS efforts. PMID- 29587728 TI - Anatomical landmarks of the intra-pelvic side-wall as sources of pain in women with and without pregnancy-related chronic pelvic pain after childbirth: a descriptive study. AB - BACKGROUND: Chronic pelvic pain (CPP) affects 15-24% of women and can have a devastating impact on quality of life. Laparoscopy is often used in the investigation, although in one third of the examinations there is no visible pathology and the women may be dismissed without further investigation. Also, the contribution of skeletal, muscular, periosteal and ligamentous tissues to CPP remains to be further elucidated. The objective of the present study was to compare pain intensity provoked from anatomical landmarks of the intra-pelvic side-wall in women with pregnancy-related CPP after childbirth and women without such pain. METHODS: This is a descriptive study of 36 non-randomly selected parous women with CPP after childbirth and 29 likewise selected parous women after childbirth without CPP. Pain was determined by questionnaire and clinical examination. The primary outcome measure was reported pain intensity provoked on 13 anatomical landmarks of the intra-pelvic side-wall. All women reported their perceived pain intensity for each anatomical landmark on Likert scales and an individual sum score was calculated. RESULTS: Women with chronic pelvic pain were older than women without CPP. At several intra-pelvic landmarks high intensity pain was provoked in women with CPP compared with less intense pain provoked at fewer landmarks in women without low back or pelvic pain (p < 0.0001). The average sum of pain intensity scores was about 4 times higher in women with CPP (1.3) as compared with those without low back or pelvic pain (0.3), p < 0.0001. This association remained when adjusting for the age difference between the pain groups in linear regression analysis. In addition, reported pain intensity at worst past week was independently associated with sum of pain intensity scores. The maximum individual sum of pain intensity scores among women without CPP was exceeded by that of 85% of the women with CPP. CONCLUSIONS: Parous women with CPP after childbirth had a heightened pain intensity over 13 anatomical landmarks during pelvic examination compared with parous women without CPP. These results need to be confirmed in a larger cohort with different types of CPP. PMID- 29587729 TI - Comparing the efficacy of targeted spinal cord stimulation (SCS) of the dorsal root ganglion with conventional medical management (CMM) in patients with chronic post-surgical inguinal pain: the SMASHING trial. AB - BACKGROUND: A significant number of patients who undergo a standard inguinal hernia repair or a Pfannenstiel incision develop chronic (> 3 months) post surgical inguinal pain (PSIP) due to nerve entrapment. If medication or peripheral nerve blocks fail, surgery including neurectomies may offer relief. However, some patients do not respond to any of the currently available remedial treatment modalities. Targeted spinal cord stimulation (SCS) of the dorsal root ganglion (DRG) is a relatively new type of therapy that has a potential to significantly reduce chronic PSIP. The Axium(r) SCS System (Spinal Modulation Inc., NY, USA) has been shown to be safe and successful in small cohorts of PSIP patients. Aim of this study is to evaluate targeted spinal cord stimulation therapy in patients with PSIP. METHODS: A prospective, multicentre, randomized controlled trial with optional one-way crossover will assess the efficacy of the Axium(r) SCS system for the treatment of PSIP. Seventy-eight patients with intractable PSIP following open hernia repair or Pfannenstiel incision who did not respond favorably to previous pain treatment regimens including a neurectomy will be randomized to either an Axium(r) SCS arm or a control arm receiving only conventional medical management (CMM). Primary outcome is the difference in percentage of subjects with >=50% pain relief after 6 months using a Numerical Pain Rating Scale (NPRS). Data are collected using a daily pain/sleep diary and a number needed to treat (NNT) analysis is performed. Various secondary outcomes will be collected. DISCUSSION: Targeted SCS stimulation of the DRG using the Axium(r) SCS system will possibly offer significant pain reduction in patients with PSIP who are refractory to other treatment modalities. TRIAL REGISTRATION: The study protocol is registered at the NIH Clinical Trials Registry ( http://clinicaltrials.gov , ClinicalTrials.gov identifier: NCT02349659 ) on January 29, 2015. PMID- 29587730 TI - Applying interprofessional Team-Based Learning in patient safety: a pilot evaluation study. AB - BACKGROUND: Interprofessional education (IPE) interventions are not always successful in achieving learning outcomes. Team-Based Learning (TBL) would appear to be a suitable pedagogical method for IPE, as it focuses on team performance; however, little is known about interprofessional TBL as an instructional framework for patient safety. In this pilot-study, we aimed to (1) describe participants' reactions to TBL, (2) observe their achievement with respect to interprofessional education learning objectives, and (3) document their attitudinal shifts with regard to patient safety behaviours. METHODS: We developed and implemented a three-day course for pre-qualifying, non-medical healthcare students to give instruction on non-technical skills related to 'learning from errors'. The course consisted of three sequential modules: 'Recognizing Errors', 'Analysing Errors', and 'Reporting Errors'. The evaluation took place within a quasi-experimental pre-test-post-test study design. Participants completed self-assessments through valid and reliable instruments such as the Mennenga's TBL Student Assessment Instrument and the University of the West of England's Interprofessional Questionnaire. The mean scores of the individual readiness assurance tests were compared with the scores of the group readiness assurance test in order to explore if students learned from each other during group discussions. Data was analysed using descriptive (i.e. mean, standard deviation), parametric (i.e. paired t-test), and non-parametric (i.e. Wilcoxon signed-rank test) methods. RESULTS: Thirty-nine students from five different bachelor's programs attended the course. The participants positively rated TBL as an instructional approach. All teams outperformed the mean score of their individual members during the readiness assurance process. We observed significant improvements in 'communication and teamwork' and 'interprofessional learning' but not in 'interprofessional interaction' and 'interprofessional relationships.' Findings on safety attitudes and behaviours were mixed. CONCLUSION: TBL was well received by the students. Our first findings indicate that interprofessional TBL seems to be a promising pedagogical method to achieve patient safety learning objectives. It is crucial to develop relevant clinical cases that involve all professions. Further research with larger sample sizes (e.g. including medical students) and more rigorous study designs (e.g. pre-test post-test with a control group) is needed to confirm our preliminary findings. PMID- 29587731 TI - Highly water pressurized brown rice improves cognitive dysfunction in senescence accelerated mouse prone 8 and reduces amyloid beta in the brain. AB - BACKGROUND: Alzheimer's disease (AD) is the most common form of dementia and the number of AD patients continues to increase worldwide. Components of the germ layer and bran of Brown rice (BR) help maintain good health and prevent AD. Because the germ layer and bran absorb little water and are very hard and difficult to cook, they are often removed during processing. To solve these problems, in this study, we tried to use a high-pressure (HP) technique. METHODS: We produced the highly water pressurized brown rice (HPBR) by pressurizing BR at 600 MPa, and then we fed it to an AD mouse model, senescence-accelerated mouse prone 8, to investigate the therapeutic effects of HPBR on cognitive dysfunction by Y-maze spatial memory test. RESULTS: HP treatment increased the water absorbency of BR without nutrient loss. HPBR ameliorated cognitive dysfunction and reduced the levels of amyloid-beta, which is a major protein responsible for AD, in the brain. CONCLUSIONS: These results suggest that HPBR is effective for preventing AD. PMID- 29587732 TI - Influence of Japan's 2004 postgraduate training on ophthalmologist location choice, supply and distribution. AB - BACKGROUND: Highly-competent patient care is paramount to medicine. Quality training and patient accessibility to physicians with a wide range of specializations is essential. Yet, poor quality of life for physicians cannot be ignored, being detrimental to patient care and leading to personnel leaving the medical profession. In 2004, the Japanese government reformed postgraduate training for medical graduates, adding a 2-year, hands-on rotation through different specialties before the specialization residency was begun. Residents could now choose practice location, but it sparked concerns that physician distribution disparities had been created. Japanese media reported that residents were choosing specialties deemed to offer a higher quality of life, like Ophthalmology or Dermatology, over underserved areas like Obstetrics or Cardiology. To explore the consequences of Japan's policy efforts, through the residency reform in 2004, to improve physician training, analyzing ophthalmologist supply and distribution in the context of providing the best possible patient care and access while maintaining physician quality of life. METHODS: Using secondary data, we analyzed changes in ophthalmologist supply at the secondary tier of medical care (STM). We applied ordinary least-squares regression models to ophthalmologist density to reflect community factors such as residential quality and access to further professional development, to serve as predictors of ophthalmologist supply. Coefficient equality tests examined predictor differences before and after 2004. Similar analyses were conducted for all physicians excluding ophthalmologists (other physicians). Ophthalmologist coverage in top and bottom 10% of STMs revealed supply inequalities. RESULTS: Change in ophthalmologist supply was inversely associated with baseline ophthalmologist density before (P < .01) and after (P = .01) 2004. Changes in other physician supply were not associated with baseline other physician density before 2004 (P = 0.5), but positively associated after 2004 (P < .01). Inequalities between top and bottom 10% of ophthalmologist supply in STMs were large, with best-served areas maintaining roughly five times greater coverage than least-served areas. However, inequalities gradually declined between 1998 and 2012. CONCLUSIONS: Ophthalmologist supply increased both before and after the 2004 reform, yet contrary to media reports, proceeded at a lesser rate than supply increases for other physicians. After 2004, geographical disparities decreased for ophthalmologists, while increasing for other physicians.

PMID- 29587734 TI - South African medicinal plant extracts active against influenza A virus. AB - BACKGROUND: Influenza infection remains a major health threat for animals and humans which crucially requires effective antiviral remedies. The usage of herbal medications as readily available alternatives for their compatibility with the body and fewer side effects compared to synthetic chemical treatments has become popular globally. The aim of this study was to investigate and screen in vitro anti-influenza activity of extracts of five South African medicinal plants, namely Tabernaemontana ventricosa, Cussonia spicata, Rapanea melanophloeos, Pittosporum viridiflorum and Clerodendrum glabrum, species which are used traditionally for the treatment of several diseases such as inflammatory and respiratory diseases. METHODS: Methanol, ethanol (100% and 30%), acetone, hot and cold water extracts of the powdered plants leaves were obtained by standard methods. The cytotoxicity was determined by the MTT colorimetric assay on MDCK cells. The concentrations below CC50 values were tested for antiviral activity against influenza A virus (IAV) in different combination treatments. The effect of extracts on viral surface glycoproteins and viral titer were tested by HI and HA virological assays, respectively. RESULTS: Based on the applied methods, the most effective results against IAV were obtained from Rapanea melanophloeos methanol leaf extract (EC50 = 113.3 MUg/ml) and Pittosporum viridiflorum methanol, 100% and 30% ethanol and acetone leaf extracts (EC50 values = 3.6, 3.4, 19.2, 82.3 MUg/ml, respectively) in all types of combined treatments especially in pre- and post-penetration combined treatments with highly significant effects against viral titer (P <= 0.01). CONCLUSION: The outcomes offer for the first time a scientific basis for the use of extracts of Rapanea melanophloeos and Pittosporum viridiflorum against IAV. It is worth focusing on the isolation and identification of effective active compounds and elucidating the mechanism of action from these species. However, Tabernaemontana ventricosa, Cussonia spicata and Clerodendrum glabrum leaf extracts were ineffective in vitro in this study.

PMID- 29587736 TI - Comparison of clinicopathologic characteristics, epigenetic biomarkers and prognosis between renal pelvic and ureteral tumors in upper tract urothelial carcinoma. AB - BACKGROUND: There's no consensus about the difference between renal pelvic and ureteral tumors in terms of clinical features, pathological outcomes, epigenetic biomarkers and prognosis. METHODS: The data of 341 patients with renal pelvic tumors and 271 patients with ureteral tumors who underwent radical nephroureterectomy between 1999 and 2011 were retrospectively reviewed. The clinicopathologic features, gene promoters methylation status and oncologic outcomes were compared. Regression analysis was performed to identify oncologic prognosticators. RESULTS: Patients with ureteral tumors were relatively older (p = 0.002), and had higher likelihood of pre-operative renal insufficiency (p < 0.001), hypertension (p = 0.038) and hydronephrosis (P < 0.001), while in patients with renal pelvic tumors gross hematuria was more prevalent (p < 0.001). Renal pelvic tumors tended to exhibit non-organ-confined disease (p = 0.004) and larger tumor diameter (p = 0.001), while ureteral tumors had a higher likelihood of exhibiting high grade (p < 0.001) and sessile architecture (p = 0.023). Hypermethylated gene promoters were significantly more prevalent in renal pelvic tumors (p < 0.001), specifically for TMEFF2, GDF15, RASSF1A, SALL3 and ABCC6 (all p < 0.05). Tumor location failed to independently predict cancer-specific survival, overall survival, intravesical or contralateral recurrence (all p > 0.05), while gene methylation status was demonstrated to be an independent prognostic factor. CONCLUSION: Renal pelvic tumors and ureteral tumors exhibited significant differences in clinicopathologic characteristics and epigenetic biomarkers. Gene promoter methylation might be an important mechanism in explaining distinct tumor patterns and behaviors in UTUC. PMID- 29587737 TI - Resident burnout: evaluating the role of the learning environment. AB - BACKGROUND: Although burnout is viewed as a syndrome rooted in the working environment and organizational culture, the role of the learning environment in the development of resident burnout remains unclear. We aimed to evaluate the association between burnout and the learning environment in a cohort of Belgian residents. METHODS: We conducted a cross-sectional online survey among residents in a large university hospital in Belgium. We used the Dutch version of the Maslach Burnout Inventory (UBOS-C) to assess burnout and the Dutch Residency Educational Climate Test (D-RECT) to assess the learning environment. RESULTS: A total of 236 residents (29 specialties) completed the survey (response rate 34.6%), of which 98 (41.5%) met standard criteria for burnout. After multivariate regression analysis adjusting for hours worked per week, quality of life and satisfaction with work-life balance, we found an inverse association between D RECT scores and the risk of burnout (adjusted odds ratio; 0.47 for each point increase in D-RECT score; 95% CI, 0.23 - 0.95; p = 0.01). CONCLUSIONS: Resident burnout is highly prevalent in our cohort of Belgian residents. Our results suggest that the learning environment plays an important role in reducing the risk of burnout among residents. PMID- 29587738 TI - The relationship between long working hours and depression among first-year residents in Japan. AB - BACKGROUND: In Japan, some residents develop mental health problems. In previous studies, it was reported that long working hours might be a cause of stress reaction such as depression. There were some reports that compared residents with 80 or more working hours with those with less than 80 working hours. However, many residents are practically detained for extra-long time, designated as 100 h or more per week, for medical practice, training, self-study, etc. There have been few reports on extra-long hours of work. This study evaluated the working environment and the amount of stress experienced by first-year residents, and examined the relationship between long working hours and depression, especially in the group of extra-long working hours. METHODS: The study included 1241 first year residents employed at 250 training hospitals in 2011. A self-report questionnaire was administered at the beginning of the residency and 3 months later to collect data on demographics, depressive symptoms, and training conditions (e.g., duration of work, sleep, disposable time, and night shift). Depressive symptoms were rated using the Center for Epidemiologic Studies Depression Scale. RESULTS: The mean duration of work per week was 79.4 h, with 97 residents (7.8%) working 100 h or more. At 3 months, clinically significant depressive symptoms were reported by 45.5% of residents working 100 or more h per week, which proportion was significantly greater than that for respondents working less than 60 h (P < 0.001). Multivariate logistic regression analysis showed that a working week of 80 to 99.9 h was associated with a 2.83 fold higher risk and 100 h or more was associated with a 6.96-fold higher risk of developing depressive symptoms compared with a working week of less than 60 h. CONCLUSION: Working excessively long hours was significantly associated with development of depressive symptoms. Proper management of resident physicians' working hours is critical to maintaining their physical and mental health and to improve the quality of care they provide. PMID- 29587739 TI - Prevalence and antimicrobial susceptibility of asymptomatic bacteriuria among women with pelvic organ prolapse in Abakaliki, South-East Nigeria. AB - BACKGROUND: Pelvic organ prolapse (POP) is the herniation of pelvic organs from its anatomical confines, and it is of considerable importance to the practicing gynaecologist in middle and low income countries. It is commonly associated with, urinary tract infection (UTI), both symptomatic and asymptomatic due to anatomical and physiological changes. The aim of this study was to determine the prevalence of asymptomatic bacteriuria among women with pelvic organ prolapse, to know the organisms commonly implicated and the sensitivity pattern. METHODS: This study was conducted among 96 women with POP at the National Obstetric Fistula Centre Abakaliki. A cross sectional descriptive study was done. Standard microbial technique was used to analyze the urine. Data was analysed using the Statistical Package for Social Sciences version 17. RESULTS: Out of the 96 patients, 76 were found to have asymptomatic bacteriuria giving a prevalence of 79.2%. Nine different bacteria species isolated include E. Coli (34.2%), Streptococcus pneumonia (23.7%), Staphylococcus aureus (7.9%), Proteus Spp (7.9%) others (5.3%). The highest level of microbial sensitivity to the antimicrobials was with Ciprofloxacin. CONCLUSIONS: This study suggests that prevalence of asymptomatic bacteriuria is very high among women with POP. More than 50% of the bacterial isolates were mainly E.coli and Streptococcus pneumonia. The highest level of microbial sensitivity was with ciprofloxacin while the least was with cotrimoxazole. PMID- 29587740 TI - A communication-focused curriculum for dental students - an experiential training approach. AB - BACKGROUND: Successful interaction and communication with patients is as vital for dentists as it is for physicians. Therefore, the aim of this study was the development and evaluation of an interactive, experiential training curriculum with an emphasis on communication for dual degree seekers of medicine and dentistry. METHODS: A pre-clinical course with an emphasis in physician/dentist patient communication and interaction was adapted by a team of subject experts based largely on the propositions of Experiential Learning Theory. After attending the course, dental students (N = 81) rated the course on a Likert- style scale and answered two open questions. RESULTS: Students found the interactive course curriculum to be very helpful and vital. Many students reported that their initial interest in the course was mainly because it is a dual degree requirement, but later on rated the course as highly important in terms of later physician/dentist-patient interaction. One aspect of the curriculum course participants regarded as very important, yet neglected during dental studies, was (self-) perception. CONCLUSION: In the view of dental students, the rigorous structure of the pre-clinical dental curriculum does not allow for time spent on topics such as (self-) perception and awareness, but training one's ability to self-reflect and think critically about one's own actions, conduct or position can aid with advanced medical and dental studies and practices later on. Experiential courses with an emphasis on patient physician/dentist communication should be offered early on during pre-clinical medical and dental studies as a regular part of the curriculum. PMID- 29587741 TI - Isolation, molecular characterization and sero-prevalence study of foot-and-mouth disease virus circulating in central Ethiopia. AB - BACKGROUND: Ethiopian livestock production and productivity is still very low due to widespread of diseases. Among the diseases, foot-and-mouth disease (FMD) is an extremely contagious and acute viral disease that causes significant economic problems in the country. A cross sectional study design was conducted from September 2015 to May 2016 to isolate and characterize FMD virus from outbreak cases; determine the sero-prevalence of antibodies against FMD virus (FMDV), and assess potential risk factors associated with sero-prevalence of the disease in selected areas of central Ethiopia. A multistage sampling technique was employed to select the study animals. Isolated viruses were characterized by antigen ELISA (IZLER, Brescia, Italy) and by genetic analysis of the sequence of the viral protein 1 (VP1). Sero-prevalence was determined using an ELISA for antibodies against non-structural proteins of FMDV based on the 3ABC proteins (ID Screen(r) FMD NSP Competition, ID-VET, Grabels, France). Risk factors for sero-prevalence of antibodies against FMD virus was investigated using logistic regression analysis. RESULT: From outbreak investigation, 28.8% (n = 378) cattle showed signs and lesions suggestive of FMD and 34 samples were subjected to virus isolation. Twenty eight of these cultures exhibited cytopathic effect (CPE) and were serotyped as O, A and SAT 2 FMD viruses. One A and two SAT 2 isolates named A-ETH-19-2015, SAT 2-ETH-18-2015 and SAT 2-ETH-20-2015 were further characterized by phylogenetic analysis. The overall sero-prevalence of antibodies against non structural proteins of FMDV was 24.2% (n = 574). Cattle herds with crossbreed cattle, with older cattle (> 2 years), and kept together with small ruminants had higher sero-prevalences of antibodies against FMDV (p < 0.05). CONCLUSION: This study showed that FMD was present in the study areas. Among the associated risk factors, breed, age and herd composition were significantly associated with presence of antibodies against FMD virus. Three different serotypes (A, O and SAT 2) were responsible for the outbreaks of the disease. Genetic analysis indicated that the isolated viruses clustered differently from previous outbreaks. Thus, further molecular analyses coupled with protection potential of the existing vaccines against the isolates should be performed. PMID- 29587742 TI - Availability, use, and affordability of medicines in urban China under universal health coverage: an empirical study in Hangzhou and Baoji. AB - BACKGROUND: This study aimed to examine the availability, use, and affordability of medicines in urban China following the 2009 Health Care System Reform that included implementation of universal health coverage (UHC). METHODS: This longitudinal study was performed in Hangzhou (high income, eastern China) and Baoji (lower income, western China). Five yearly household surveys were conducted (one each year from 2009 to 2013) to evaluate the impact of UHC on medicines use and expenditure, and a health facility survey was conducted in 2013 to evaluate availability of medicines. A cohort of over 800 households in Hangzhou and Baoji was established in 2009, and 20 hospitals were included in the health facility survey. Medicines use was determined using data from health facility and household surveys. An average, two-week out-of-pocket medicines expenditure was calculated to assess the affordability of medicines. RESULTS: The number of medicines stocked in primary health facilities in Hangzhou decreased, while the number in Baoji increased. In Baoji, patients usually chose a pharmacy to buy medicines directly, despite the 48.2% increased availability of essential medicines in primary health care centers. The majority of survey respondents stated that their medicines need was basically met; however, medicines cost still accounted for a major part of their health expenditure. Medicines expenditure showed an increasing trend from 2009 to 2013. The average annual growth rate of household overall medical expenditure was significantly higher than that for household non-food consumption expenditure. CONCLUSIONS: Following China's Health Care System Reform and implementation of UHC, availability and use of medicines has improved in urban areas. However, the affordability of medicines is still a concern. PMID- 29587743 TI - Proteomic analysis of antimicrobial effects of pegylated silver coated carbon nanotubes in Salmonella enterica serovar Typhimurium. AB - BACKGROUND: Synthesis of silver nano-compounds with enhanced antimicrobial effects is of great interest for the development of new antibacterial agents. Previous studies have reported the antibacterial properties of pegylated silver coated carbon nanotubes (pSWCNT-Ag) showing less toxicity in human cell lines. However, the mechanism underlining the pSWCNT-Ag as a bactericidal agent remained unfolded. Here we assessed the pSWCNT-Ag effects against foodborne pathogenic bacteria growth and proteome profile changes. RESULTS: Measurements of bioluminescent imaging, optical density, and bacteria colony forming units revealed dose-dependent and stronger bactericidal activity of pSWCNT-Ag than their non-pegylated counterparts (SWCNT-Ag). In ovo administration of pSWCNT-Ag or phosphate-buffered saline resulted in comparable chicken embryo development and growth. The proteomic analysis, using two-dimensional electrophoresis combined with matrix assisted laser desorption/ionization time of flight/time of flight mass spectrometry, was performed on control and surviving Salmonella enterica serovar Typhimurium to pSWCNT-Ag. A total of 15 proteins (ten up regulated and five down-regulated) differentially expressed proteins were identified. Functional analyses showed significant reduction of proteins associated with biofilm formation, nutrient and energy metabolism, quorum sensing and maintenance of cell structure and cell motility in surviving S. Typhimurium. In contrast, proteins associated with oxygen stress, DNA protection, starvation, membrane rebuilding, and alternative nutrient formation were induced as the compensatory reaction. CONCLUSIONS: This study provides further evidence of the antibacterial effects of pSWCNT-Ag nanocomposites and knowledge of their mechanism of action through various protein changes. The findings may lead to the development of more effective and safe antimicrobial agents. PMID- 29587744 TI - Safety and efficacy of the mesenchymal stem cell in feline eosinophilic keratitis treatment. AB - BACKGROUND: Feline eosinophilic keratitis (FEK) is a chronic keratopathy caused by a suspected immune mediated response to an unknown antigenic stimulus. The purpose of this study was to investigate the safety and therapeutic effects of allogeneic feline adipose-derived mesenchymal stromal cells (fAd-MSCs) implanted subconjunctival around the ocular surface lesion in five cats with FEK refractory to current available treatments. RESULTS: FEK was diagnosed by clinical appearance and evidence of eosinophil and/or mast cells in corneal cytology. Each animal was treated with two applications of 2 * 106 million of fAd-MSCs 2 months apart. Ocular surface integrity was assessed before treatment and at 1, 3, 6 and 11 months after treatment. Clinical signs showed a significant change during the follow-up with resolution of the corneal and conjunctiva lesions and there were no signs of regression or worsening. CONCLUSIONS: Implanted cells were well tolerated and effective reducing clinical signs of FEK with a sustained effect during the study period. None of the animals showed systemic or local complications during the study. To our knowledge, this is the first time in literature that local implantation of allogeneic fAd-MSCs has been found as an effective therapeutic alternative to treat cats with FEK. PMID- 29587745 TI - High antiretroviral therapy service delivery satisfaction and its' associated factors at Midre-genet hospital; Northwest Tigray, Ethiopia. AB - BACKGROUND: Patient's satisfaction occurs when patients feel their needs and expectations are being meet by the service delivery they receive in health institutions. The Objective of this research was to assess HIV/AIDS patients' satisfaction with antiretroviral therapy service delivery and its associated factors at Midre - Genet hospital, Northwest Tigray, Ethiopia. METHODS: Institutional based cross-sectional study was conducted. Four hundred twenty study respondents were selected using systematic random sampling technique. Data was collected using pretested, structured interview questionnaire. Bivariate analysis was conducted to identify potential significantly associated variables and transferred to multivariate logistic regression analysis. P value < 0.05 is used to demarcate significantly associated variables. RESULT: The overall HIV/AIDS patients'satisfaction on antiretroviral therapy service delivery at Midre-Genet referral hospital was 75.2%. Multivariate analysis revealed age, marital status, occupation, income, information provision and guidance, privacy, access of toilets and interpersonal communication as significantly associated factors with patient's satisfaction on ART service delivery. CONCLUSION: The overall HIV/AIDS patients' satisfaction at Midre-Genet referral hospital was high. Age, marital status, occupation and, income was associated factors. Moreover, lack of functional CD4 machine, inaccessibility of toilets and water, waiting time, inadequate counseling services and lack of qualified health worker (Doctor) in the ART clinic were also challenges for ART patients in the hospital. PMID- 29587746 TI - Do students from public schools fare better in medical school than their colleagues from private schools? If so, what can we learn from this? AB - BACKGROUND: Internal grade inflation is a documented practice in secondary schools (mostly in private schools) that jeopardises fairness with regard to access to medical school. However, it is frequently assumed that the higher internal grades are in fact justifiable, as they correspond to better preparation of students in private schools in areas that national exams do not cover but nevertheless are important. Consequently, it is expected that students from private schools will succeed better in medical school than their colleagues, or at least not perform worse. We aimed to study whether students from private schools do fare better in medical school than their colleagues from public schools, even after adjusting for internal grade inflation. METHODS: We analysed all students that entered into a medical course from 2007 to 2014. A linear regression was performed using mean grades for the 1st-year curse units (CU) of the medical school curriculum as a dependent variable and student gender, the nature of students' secondary school (public/private), and whether their secondary school highly inflated grades as independent variables. A logistic regression was also performed, modelling whether or not students failed at least one CU exam during the 1st year of medical school as a function of the aforementioned independent variables. RESULTS: Of the 1709 students analysed, 55% came from public secondary schools. Private (vs. public) secondary school (beta = - 0.459, p < 0.001) and whether secondary schools highly inflated grades (beta = 0.246, p = 0.003) were independent factors that significantly influenced grades during the first year of medical school. Having attended a private secondary school also significantly increased the odds of a student having failed at least one CU exam during the 1st year of medical school (OR = 1.33), even after adjusting for whether or not the secondary school used highly inflated grades. CONCLUSIONS: It is important to further discuss what we can learn from the fact that students from public secondary schools seem to be better prepared for medical school teaching methodologies than their colleagues from private ones and the implications for the selection process. PMID- 29587747 TI - Memantine loaded PLGA PEGylated nanoparticles for Alzheimer's disease: in vitro and in vivo characterization. AB - BACKGROUND: Memantine, drug approved for moderate to severe Alzheimer's disease, has not shown to be fully effective. In order to solve this issue, polylactic-co glycolic (PLGA) nanoparticles could be a suitable solution to increase drug's action on the target site as well as decrease adverse effects. For these reason, Memantine was loaded in biodegradable PLGA nanoparticles, produced by double emulsion method and surface-coated with polyethylene glycol. MEM-PEG-PLGA nanoparticles (NPs) were aimed to target the blood-brain barrier (BBB) upon oral administration for the treatment of Alzheimer's disease. RESULTS: The production parameters were optimized by design of experiments. MEM-PEG-PLGA NPs showed a mean particle size below 200 nm (152.6 +/- 0.5 nm), monomodal size distribution (polydispersity index, PI < 0.1) and negative surface charge (- 22.4 mV). Physicochemical characterization of NPs confirmed that the crystalline drug was dispersed inside the PLGA matrix. MEM-PEG-PLGA NPs were found to be non-cytotoxic on brain cell lines (bEnd.3 and astrocytes). Memantine followed a slower release profile from the NPs against the free drug solution, allowing to reduce drug administration frequency in vivo. Nanoparticles were able to cross BBB both in vitro and in vivo. Behavioral tests carried out on transgenic APPswe/PS1dE9 mice demonstrated to enhance the benefit of decreasing memory impairment when using MEM-PEG-PLGA NPs in comparison to the free drug solution. Histological studies confirmed that MEM-PEG-PLGA NPs reduced beta-amyloid plaques and the associated inflammation characteristic of Alzheimer's disease. CONCLUSIONS: Memantine NPs were suitable for Alzheimer's disease and more effective than the free drug. PMID- 29587749 TI - FOLFIRI plus panitumumab in the treatment of wild-type KRAS and wild-type NRAS metastatic colorectal cancer. AB - BACKGROUND: The aim of this study was to investigate the efficacy and safety of first-line panitumumab plus folinic acid, 5-fluorouracil and irinotecan (FOLFIRI) in patients with wild-type KRAS and wild-type NRAS metastatic colorectal cancer (mCRC). METHODS: Patients with wild-type KRAS and wild-type NRAS mCRC presenting to the medical oncology department of the Okmeydani Training and Research Hospital in Istanbul, Turkey, between April 2014 and January 2018 were enrolled in this study. RESULTS: A total of 64 patients (35 males and 29 females) with a median age of 59 (35-81) years old were enrolled. The median follow-up was 18.9 months, and the median progression-free survival was 13 months. The median overall survival (OS) was 26 months in the patients with wild-type KRAS and wild type NRAS mCRC. It was 90.4% for the 6-month OS, 79.5% for the 1-year OS, 53.7% for the 2-year OS and 31.1% for the 3-year OS. The median OS of the patients who underwent metastasectomies was 40 [95% confidence interval (CI) = 19.9-60.1] months, and the median OS of the patients without metastasectomies was 22 (95% CI = 17.7-26.4) months. There was a statistically significant difference between these (P = 0.007). CONCLUSION: The first-line FOLFIRI plus panitumumab was associated with favourable efficacy in the patients with wild-type KRAS and wild type NRAS mCRC, and it was well tolerated. The removal of the metastases that became resectable after chemotherapy further prolonged the patients' survival. TRIAL REGISTRATION: Retrospectively registered: 33886. PMID- 29587748 TI - Regulation of alveolar macrophage death in acute lung inflammation. AB - Acute lung injury (ALI) and its severe form, known as acute respiratory distress syndrome (ARDS), are caused by direct pulmonary insults and indirect systemic inflammatory responses that result from conditions such as sepsis, trauma, and major surgery. The reciprocal influences between pulmonary and systemic inflammation augments the inflammatory process in the lung and promotes the development of ALI. Emerging evidence has revealed that alveolar macrophage (AM) death plays important roles in the progression of lung inflammation through its influence on other immune cell populations in the lung. Cell death and tissue inflammation form a positive feedback cycle, ultimately leading to exaggerated inflammation and development of disease. Pharmacological manipulation of AM death signals may serve as a logical therapeutic strategy for ALI/ARDS. This review will focus on recent advances in the regulation and underlying mechanisms of AM death as well as the influence of AM death on the development of ALI. PMID- 29587750 TI - Three-dimensional experiments and individual based simulations show that cell proliferation drives melanoma nest formation in human skin tissue. AB - BACKGROUND: Melanoma can be diagnosed by identifying nests of cells on the skin surface. Understanding the processes that drive nest formation is important as these processes could be potential targets for new cancer drugs. Cell proliferation and cell migration are two potential mechanisms that could conceivably drive melanoma nest formation. However, it is unclear which one of these two putative mechanisms plays a dominant role in driving nest formation. RESULTS: We use a suite of three-dimensional (3D) experiments in human skin tissue and a parallel series of 3D individual-based simulations to explore whether cell migration or cell proliferation plays a dominant role in nest formation. In the experiments we measure nest formation in populations of irradiated (non-proliferative) and non-irradiated (proliferative) melanoma cells, cultured together with primary keratinocyte and fibroblast cells on a 3D experimental human skin model. Results show that nest size depends on initial cell number and is driven primarily by cell proliferation rather than cell migration. CONCLUSIONS: Nest size depends on cell number, and is driven primarily by cell proliferation rather than cell migration. All experimental results are consistent with simulation data from a 3D individual based model (IBM) of cell migration and cell proliferation. PMID- 29587751 TI - Plasma angiopoietin-like 4 is related to phospholipid transfer protein activity in diabetic and non-diabetic subjects: role of enhanced low grade inflammation. AB - BACKGROUND: Angiopoietin-like 4 (ANGPTL4) inhibits lipoprotein lipase, whereas phospholipid transfer protein (PLTP) enhances hepatic triglyceride secretion. Both factors may be upregulated by inflammatory pathways. Since the extent to which these circulating factors are interrelated is unknown, we determined the relationship between plasma ANGPTL4 and PLTP activity, and assessed whether such a relationship could be explained by high sensitivity C-reactive protein (hsCRP) levels as a marker of low-grade chronic inflammation. METHODS: Fasting plasma ANGPTL4, PLTP activity (liposome-vesicle high density lipoprotein system) and hsCRP were measured in 41 type 2 diabetic (T2DM) subjects and 36 non-diabetic subjects. RESULTS: Plasma ANGPTL4 and PLTP activity were increased in T2DM (p < 0.001 for each), coinciding with elevated hsCRP, triglycerides and non-esterified fatty acids (NEFA) (p = 0.031 to 0.001). In univariate analysis, ANGTLP4 was correlated with PLTP activity (Rs = 0.309, p = 0.006), whereas both factors were related to hsCRP and NEFA levels (Rs = 0.304 to 0.411, p < 0.01 to < 0.001). In multivariable linear regression analysis adjusting for age, sex, glucose, total cholesterol, triglycerides and NEFA, ANGPTL4 and PLTP activity each remained positively associated with hsCRP (beta = 0.315, p = 0.003 and beta = 0.299, p = 0.034, respectively). Plasma ANGPTL4 remained positively associated with PLTP activity when taking account of age, sex, glucose, total cholesterol, triglycerides and NEFA (beta = 0.315, p = 0.003). Notably, this association disappeared after further adjustment for hsCRP (beta = 0.131, p = 0.25). CONCLUSIONS: In conclusion, plasma ANGPTL4 and PLTP activity are interrelated, which may at least in part be explained by low-grade chronic inflammation. A pro inflammatory state could affect triglyceride metabolism via concerted effects on ANGPTL4 and PLTP. PMID- 29587752 TI - Alzheimer-like brain metabolic and structural features in cholesterol-fed rabbit detected by magnetic resonance imaging. AB - BACKGROUND: Hypercholesterolemia is known to increase the risk of AD in later life, the purpose of this study is to illustrate brain metabolic and structural changes in a cholesterol-fed rabbit model of Alzheimer's Disease (AD) by using clinical 3 T Magnetic Resonance Imaging (MRI). METHODS: The Institutional Animal Care and Use Committee of Zhejiang Chinese Medical University approved the study. Totally 16 Japanese White Rabbits (JWR) were randomly divided into 2 groups including normal control group fed with routine diet (group NC) and high cholesterol diet group (group CD) fed a 2% cholesterol diet with 0.24 ppm copper in the drinking water for 12 weeks. Magnetic resonance spectroscopy (MRS) and structural image of rabbit brain were performed by using a 3 Tesla (T) MRI scanner with an 8 channel Rabbit coil. The chemical metabolites were identified by LC Model including N-acetylaspartate (NAA), creatine (Cr), glutamate (Glu), glutamine (Gln), Glycerophosphatidylcholine (GPC), phosphorylcholine (PCH), and myoinositol (MI). The relative concentrations (/Cr) were analyzed. Additionally, Amyloid-beta (Abeta) accumulation in the brain was measured postmortem. For comparisons of MR and Abeta data between groups, two-tailed t-tests were performed. RESULTS: The ratio of NAA/Cr (0.76 +/- 0.10) and Glu/Cr (0.90 +/- 0.14) in group CD were lower than those in the group NC (0.87 +/- 0.06, 1.13 +/- 0.22, respectively, P < 0.05). Compared to the group NC (2.88 +/- 0.09 cm3, 0.63 +/- 0.08 cm3, respectively), the cortical and hippocampal volumes (2.60 +/- 0.14 cm3 and 0.47 +/- 0.07 cm3, respectively) of rabbits brain decreased in the group CD while the third and lateral ventricular volumes enlarged (44.56 +/- 6.01 mm3 vs 31.40 +/- 6.14 mm3, 261.40 +/- 30.98 mm3 vs 153.81 +/- 30.08 mm3, P < 0.05). These metabolic and structural changes were additionally accompanied by the significant increase of Abeta1-42 in the cortex and hippocampus (163.60 +/- 16.26 pg/mg and 215.20 +/- 69.86 pg/mg, respectively, P < 0.05). CONCLUSION: High cholesterol diet can induce the brain metabolic and structural changes of the rabbit including lowered level of NAA and Glu and the atrophy of the brain which were similar to those of human AD. PMID- 29587753 TI - Exposure to hazardous air pollutants and risk of incident breast cancer in the nurses' health study II. AB - BACKGROUND: Findings from a recent prospective cohort study in California suggested increased risk of breast cancer associated with higher exposure to certain carcinogenic and estrogen-disrupting hazardous air pollutants (HAPs). However, to date, no nationwide studies have evaluated these possible associations. Our objective was to examine the impacts of mammary carcinogen and estrogen disrupting HAPs on risk of invasive breast cancer in a nationwide cohort. METHODS: We assigned HAPs from the US Environmental Protection Agency's 2002 National Air Toxics Assessment to 109,239 members of the nationwide, prospective Nurses' Health Study II (NHSII). Risk of overall invasive, estrogen receptor (ER)-positive (ER+), and ER-negative (ER-) breast cancer with increasing quartiles of exposure were assessed in time-varying multivariable proportional hazards models, adjusted for traditional breast cancer risk factors. RESULTS: A total of 3321 invasive cases occurred (2160 ER+, 558 ER-) during follow-up 1989 2011. Overall, there was no consistent pattern of elevated risk of the HAPs with risk of breast cancer. Suggestive elevations were only seen with increasing 1,2 dibromo-3-chloropropane exposures (multivariable adjusted HR of overall breast cancer = 1.12, 95% CI: 0.98-1.29; ER+ breast cancer HR = 1.09; 95% CI: 0.92, 1.30; ER- breast cancer HR = 1.14; 95% CI: 0.81, 1.61; each in the top exposure quartile compared to the lowest). CONCLUSIONS: Exposures to HAPs during adulthood were not consistently associated with an increased risk of overall or estrogen receptor subtypes of invasive breast cancer in this nationwide cohort of women. PMID- 29587754 TI - Retrograde intubation in a dog with severe temporomandibular joint ankylosis: case report. AB - BACKGROUND: Orotracheal intubation in dogs is a common and easily-performed procedure that provides a patent airway during anaesthesia. In dogs with temporomandibular joint ankylosis or pseudo-ankylosis, airway management can be a challenging procedure since these dogs have a limited ability to open their mouth. Methods to provide safe, uneventful intubation in such patients may include minimally invasive techniques such as retrograde intubation using a guide wire and fibre-optic-aided laryngoscopy. CASE PRESENTATION: We report a case of a 16-month-old, intact female Bull Terrier weighing 17 kg, admitted to the hospital for surgical treatment of bilateral ankylosis of the temporomandibular joint. Intubation was achieved, without direct observation of the larynx, by retrograde intubation using a vascular access catheter and a vascular wire guide through cricothyroid membrane. Bilateral condylectomy was performed and the dog recovered uneventfully. CONCLUSIONS: In conclusion, retrograde intubation was relatively simple to perform with the guide wire technique and no specific training or equipment were necessary. PMID- 29587755 TI - Torulene and torularhodin: "new" fungal carotenoids for industry? AB - Torulene and torularhodin represent the group of carotenoids and are synthesized by yeasts and fungi. The most important producers of these two compounds include yeasts of Rhodotorula and Sporobolomyces genera. The first reports confirming the presence of torulene and torularhodin in the cells of microorganisms date to the 1930s and 1940s; however, only in the past few years, the number of works describing the properties of these compounds increased. These compounds have strong anti-oxidative and anti-microbial properties, and thus may be successfully used as food, feedstock, and cosmetics additives. In addition, tests performed on rats and mice showed that both torulene and torularhodin have anti-cancerous properties. In order to commercialize the production of these two carotenoids, it is necessary to obtain highly efficient yeast strains, for example, via mutagenization and optimization of cultivation conditions. Further studies on the activity of torulene and torularhodin on the human body are also needed. PMID- 29587756 TI - The effect of industry-related air pollution on lung function and respiratory symptoms in school children. AB - BACKGROUND: Heavy industry emits many potentially hazardous pollutants into the air which can affect health. However, the effects of air pollution from heavy industry on lung function and respiratory symptoms have been investigated scarcely. Our aim was to investigate the associations of long-term air pollution from heavy industry with lung function and respiratory symptoms in school children. METHODS: A cross-sectional lung function study was conducted among school children (7-13 years) in the vicinity of an area with heavy industry. Lung function measurements were conducted during school hours. Parents of the children were asked to complete a questionnaire about the health of their children. A dispersion model was used to characterize the additional individual-level exposures to air pollutants from the industry in the area. Associations between PM2.5 and NOX exposure with lung function and presence of respiratory symptoms were investigated by linear and/or logistic regression analysis. RESULTS: Participation in the lung function measurements and questionnaires was 84% (665/787) and 77% (603/787), respectively. The range of the elevated PM2.5 and NOX five years average concentrations (2008-2012) due to heavy industry were 0.04 1.59 MUg/m3 and 0.74-11.33 MUg/m3 respectively. After adjustment for confounders higher exposure to PM2.5 and NOX (per interquartile range of 0.56 and 7.43 MUg/m3 respectively) was associated with lower percent predicted peak expiratory flow (PEF) (B -2.80%, 95%CI -5.05% to - 0.55% and B -3.67%, 95%CI -6.93% to - 0.42% respectively). Higher exposure to NOX (per interquartile range of 7.43 MUg/m3) was also associated with lower percent forced vital capacity (FVC) and percent predicted forced expiration volume in 1 s (FEV1) (B -2.30, 95% CI -4.55 to - 0.05 and B -2.73, 95%CI -5.21 to - 0.25 respectively). No significant associations were found between the additional exposure to PM2.5 or NOX and respiratory symptoms except for PM2.5 and dry cough (OR 1.40, 95%CI 1.00 to 1.94). CONCLUSION: Exposure to PM2.5 and NOX from industry was associated with decreased lung function. Exposure to PM2.5 was also associated with parents' reports of dry cough among their children. PMID- 29587757 TI - Single metastasis of myxoid liposarcoma from the thigh to thyroid gland: a case report. AB - BACKGROUND: Thyroid metastasis of soft tissue sarcoma is very rare, and the diagnosis is especially difficult when only a single lesion is present. CASE PRESENTATION: A 50-year-old man was diagnosed with myxoid liposarcoma of the right thigh and treated with wide resection. Two and a half years after the surgery, a growing low-density area was incidentally observed in the right lobe of his thyroid gland on follow-up chest computed tomography. Fine needle aspiration biopsy was performed twice, and the thyroid mass was suspected of being a sarcoma metastasis. He was treated by hemithyroidectomy, and the lesion was pathologically confirmed as a metastasis of myxoid liposarcoma. CONCLUSION: We experienced single thyroid gland metastasis in patients with myxoid liposarcoma in whom a growing mass is observed in the thyroid gland after radical surgery of the primary site. PMID- 29587758 TI - Prediction equations of forced oscillation technique: the insidious role of collinearity. AB - Many studies have reported reference data for forced oscillation technique (FOT) in healthy children. The prediction equation of FOT parameters were derived from a multivariable regression model examining the effect of age, gender, weight and height on each parameter. As many of these variables are likely to be correlated, collinearity might have affected the accuracy of the model, potentially resulting in misleading, erroneous or difficult to interpret conclusions.The aim of this work was: To review all FOT publications in children since 2005 to analyze whether collinearity was considered in the construction of the published prediction equations. Then to compare these prediction equations with our own study. And to analyse, in our study, how collinearity between the explanatory variables might affect the predicted equations if it was not considered in the model. The results showed that none of the ten reviewed studies had stated whether collinearity was checked for. Half of the reports had also included in their equations variables which are physiologically correlated, such as age, weight and height. The predicted resistance varied by up to 28% amongst these studies. And in our study, multicollinearity was identified between the explanatory variables initially considered for the regression model (age, weight and height). Ignoring it would have resulted in inaccuracies in the coefficients of the equation, their signs (positive or negative), their 95% confidence intervals, their significance level and the model goodness of fit. In Conclusion with inaccurately constructed and improperly reported models, understanding the results and reproducing the models for future research might be compromised. PMID- 29587759 TI - Anxiety and its predictive value for pain and regular analgesic intake after lumbar disc surgery - a prospective observational longitudinal study. AB - BACKGROUND: Ongoing pain after surgery is a major problem and influences recovery and the quality of life of the patient. Associations between anxiety and their impact on postoperative pain after herniated disc surgery have been reported, but the results are inconsistent. The aim of the present longitudinal study was to evaluate the predictive value of preoperative anxiety for postoperative ongoing pain and prolonged analgesic intake after herniated disc surgery. METHODS: 106 patients with lumbar disc herniation were evaluated in the study. Anxiety was measured with the Generalized Anxiety Disorder 7-Item Scale (GAD-7) before surgery. Pain intensity was assessed on a numeric rating scale (NRS) at baseline, 6-weeks and 6-months after surgery. Regression analysis was performed to identify independent predictors of pain and regular utilization of analgesics up to 6 months after surgery while controlling for confounding variables. RESULTS: 42.5% of the patients were rated as anxiety cases (sum scores GAD-7 > 5), mean scores of anxiety showed mild to moderate symptom severity, and 43% suffered from chronic pain before surgery. Six months after surgery, 55.6% of the patients indicated pain levels of 4/10 (NRS) or higher and about 40% still took pain medication on a regular basis, regardless of their preoperative classification as anxiety-case (37.7% and 41.5%). The preoperative pain level was statistically significant for ongoing postsurgical pain in all four analyses (p < 0.001). With binary logistic regression analyses, preoperative pain intensity, but neither demographic factors nor preoperative anxiety, was identified as predictor for postoperative pain and need for analgesic medication up to 6 months after lumbar disc surgery. CONCLUSION: We found no evidence for the presence of anxiety before disc surgery being a prognostic factor for ongoing pain and regular postoperative intake of analgesics. Only preoperative pain intensity was predictive for increased pain and continued need for analgesic medication up to 6 months after lumbar disc surgery. TRIAL REGISTRATION: Clinicaltrials.gov NCT01488617 . Registered 6 December 2011. PMID- 29587760 TI - The prognostic significance of topoisomerase II alpha protein in early stage luminal breast cancer. AB - BACKGROUND: Topoisomerase II alpha (TOP2A) protein has been shown to be a proliferation marker associated with tumor grade and Ki67 index. The prognostic effect of TOP2A seems different among different subtypes of breast cancer. The current study evaluated the prognostic impact of TOP2A protein on luminal breast cancer. METHOD: Altogether 434 stage I-II luminal breast cancer patients who underwent curative surgery in Sun Yat-Sen University Cancer Center between 2007 and 2009 were enrolled. TOP2A protein expression was assessed by immunohistochemistry. Clinical and pathological data were retrospectively collected. RESULT: With a cut-off value of 30%, 127 (29.3%) patients were classified as TOP2A overexpression. TOP2A overexpression was associated with a higher tumor grade and Ki67 index. Patients with TOP2A high expression showed a significantly higher rate of distant metastasis and shorter distant metastasis free survival (DMFS) compared with patients with low TOP2A expression. The prognostic influence of TOP2A expression was more significant in years 5-8 after diagnosis, and more pronounced in stage II patients, luminal B disease, and patients treated with adjuvant endocrine therapy alone. Multivariate survival analysis revealed TOP2A overexpression was an independent fact for worse DMFS. CONCLUSION: TOP2A protein showed a time dependent influence on prognosis in stage I-II luminal breast cancer, suggesting it might be a potential predictor of late recurrence for this group of patients. PMID- 29587762 TI - Analysis of medication consultation networks and reporting medication errors: a mixed methods study. AB - BACKGROUND: To examine characteristics of verbal consultation about medication within social networks of hospital inpatient medication system, and their associations with medication error reporting. METHOD: The setting was a 90-bed provincial district hospital with 4 wards, 7 physicians, 5 pharmacists, 44 nurses, 5 pharmacist assistants, and 4 unskilled ancillary workers. A mixed method comprising (i) a prospective observational study for investigating incidences and the nature of reporting medication errors, and (ii) a social network analysis for patterns of interaction. RESULTS: Out of 5296 prescriptions, 132 medication errors were reported during the one month study period: an incidence rate of 2.5%. Every incident of medication errors was formally documented through pharmacists. The most frequent medication errors were in pre transcribing (n = 54; 40.9%). The pharmacists were central in the whole network of consultation on medication with the mean in-degree centrality of 35 (SD 14.9) and mean out-degree centrality of 15.4 (SD 11.1). Two bridging participants were identified who were influential communicators connecting the network (betweenness centrality). Medication error reporting were influenced by (i) participants whose advice is sought and viewed as trustworthy (in-degree centrality; p < 0.001), (ii) sex (p = 0.01), and (iii) level of education (p = 0.04). CONCLUSION: In degree centrality was the most important network characteristic. A culture of medication safety can be fostered by encouraging consultation about the medication of in-patients within the hospital network where reporting of medication errors is essential. PMID- 29587761 TI - Evaluation of oxidative stress biomarkers in idiopathic pulmonary fibrosis and therapeutic applications: a systematic review. AB - INTRODUCTION: Idiopathic pulmonary fibrosis (IPF), a fatal lung disease of unknown origin, is characterized by chronic and progressive fibrosing interstitial pneumonia which progressively impairs lung function. Oxidative stress is one of the main pathogenic pathways in IPF. The aim of this systematic review was to describe the type of markers of oxidative stress identified in different biological specimens and the effects of antioxidant therapies in patients with IPF. METHODS: We conducted a systematic search of publications listed in electronic databases (Pubmed, Web of Science, Scopus and Google Scholar) from inception to October 2017. Two investigators independently reviewed all identified articles to determine eligibility. RESULTS: After a substantial proportion of the initially identified articles (n = 554) was excluded because they were duplicates, abstracts, irrelevant, or did not meet the selection criteria, we identified 30 studies. In each study, we critically appraised the type, site (systemic vs. local, e.g. breath, sputum, expired breath condensate, epithelial lining fluid, bronchoalveolar lavage, and lung tissue specimens), and method used for measuring the identified oxidative stress biomarkers. Furthermore, the current knowledge on antioxidant therapies in IPF was summarized. CONCLUSIONS: A number of markers of oxidative stress, with individual advantages and limitations, have been described in patients with IPF. Nevertheless, trials of antioxidant treatments have been unable to demonstrate consistent benefits, barring recent pharmacogenomics data suggesting different results in specific genotype subgroups of patients with IPF. PMID- 29587763 TI - On designing of a low leakage patient-centric provider network. AB - BACKGROUND: When a patient in a provider network seeks services outside of their community, the community experiences a leakage. Leakage is undesirable as it typically leads to higher out-of-network cost for patient and increases barrier for care coordination, which is particularly problematic for Accountable Care Organization (ACO) as the in-network providers are financially responsible for quality of care and outcome. We aim to design a data-driven method to identify naturally occurring provider networks driven by diabetic patient choices, and understand the relationship among provider composition, patient composition, and service leakage pattern. By doing so, we learn the features of low service leakage provider networks that can be generalized to different patient population. METHODS: Data used for this study include de-identified healthcare insurance administrative data acquired from Capital District Physicians' Health Plan (CDPHP) for diabetic patients who resided in four New York state counties (Albany, Rensselaer, Saratoga, and Schenectady) in 2014. We construct a healthcare provider network based on patients' historical medical insurance claims. A community detection algorithm is used to identify naturally occurring communities of collaborating providers. For each detected community, a profile is built using several new key measures to elucidate stakeholders of our findings. Finally, import-export analysis is conducted to benchmark their leakage pattern and identify further leakage reduction opportunity. RESULTS: The design yields six major provider communities with diverse profiles. Some communities are geographically concentrated, while others tend to draw patients with certain diabetic co-morbidities. Providers from the same healthcare institution are likely to be assigned to the same community. While most communities have high within-community utilization and spending, at 85% and 86% respectively, leakage still persists. Hence, we utilize a metric from import-export analysis to detect leakage, gaining insight on how to minimize leakage. CONCLUSIONS: We identify patient-driven provider organization by surfacing providers who share a large number of patients. By analyzing the import-export behavior of each identified community using a novel approach and profiling community patient and provider composition we understand the key features of having a balanced number of PCP and specialists and provider heterogeneity. PMID- 29587764 TI - pH-responsive theranostic nanocomposites as synergistically enhancing positive and negative magnetic resonance imaging contrast agents. AB - BACKGROUND: The rational design of theranostic nanoprobe to present responsive effect of therapeutic potency and enhanced diagnostic imaging in tumor milieu plays a vital role for efficient personalized cancer therapy and other biomedical applications. We aimed to afford a potential strategy to pose both T1- and T2 weighted MRI functions, and thereby realizing imaging guided drug delivery and targeted therapy. RESULTS: Theranostic nanocomposites Mn-porphyrin&Fe3O4@SiO2@PAA cRGD were fabricated and characterized, and the nanocomposites were effectively used in T1- and T2-weighted MRI and pH-responsive drug release. Fluorescent imaging also showed that the nanocomposites specifically accumulated in lung cancer cells by a receptor-mediated process, and were nontoxic to normal cells. The r2/r1 ratio was 20.6 in neutral pH 7.4, which decreased to 7.7 in acidic pH 5.0, suggesting the NCs could act as an ideal T1/T2 dual-mode contrast agent at acidic environments of tumor. For in vivo MRI, T1 and T2 relaxation was significantly accelerated to 55 and 37%, respectively, in the tumor after i.v. injection of nanocomposites. CONCLUSION: The synthesized nanocomposites exhibited highly sensitive MRI contrast function no matter in solution, cells or in vivo by synergistically enhancing positive and negative magnetic resonance imaging signals. The nanocomposites showed great potential for integrating imaging diagnosis and drug controlled release into one composition and providing real time imaging with greatly enhanced diagnostic accuracy during targeted therapy. PMID- 29587765 TI - Occupational exposure to asphalt mixture during road paving is related to increased mitochondria DNA copy number: a cross-sectional study. AB - BACKGROUND: Asphalt workers are exposed to polyaromatic hydrocarbons (PAHs) from hot mix asphalt via both inhalation and dermal absorption. The use of crumb rubber modified (CRM) asphalt may result in higher exposure to PAHs and more adverse effects. Our aim is to assess occupational exposure to PAHs from conventional and CRM asphalt paving by measuring PAH metabolites in urine, and to investigate the effects on mitochondrial DNA copy number (mtDNAcn) and telomere length. METHODS: We recruited 116 workers paving conventional asphalt, 51 workers paving CRM asphalt and 100 controls in Sweden, all males. A repeated-measures analysis included 31 workers paving both types of asphalt. Urine and blood samples were collected pre-working on Monday morning and post-working on Thursday afternoon after 4 days working. PAH metabolites: 1-hydroxypyrene (1-OH-PYR) and 2 hydroxyphenanthrene (2-OH-PH) were measured in urine by LC-MS/MS. Relative mtDNAcn and telomere length were measured by quantitative PCR. RESULTS: Conventional and CRM asphalt workers showed higher 1-OH-PYR and 2-OH-PH than controls (p < 0.001 for all). Relative mtDNAcn were 0.21 units (p < 0.001) higher in conventional asphalt workers and 0.13 units (p = 0.010) higher in CRM asphalt workers compared to controls. Relative telomere length did not differ across occupational groups, but it was positively associated with increment of 2-OH-PH (beta = 0.075, p = 0.037) in asphalt workers. The repeated-measures analysis showed no difference in either increment of 1-OH-PYP, or changes in effect biomarkers (mtDNAcn or telomere length) between paving with conventional and CRM asphalt. Increment of 2-OH-PH was smaller after paving with CRM asphalt. CONCLUSIONS: Road asphalt paving in open areas resulted in PAHs exposure, as shown by elevation of PAH metabolites in urine. Asphalt workers may experience oxidative stress, evidenced by alternation in mtDNAcn; however the effects could not be fully explained by exposure to PAHs from the asphalt mixture. PMID- 29587766 TI - ADRB3 polymorphism rs4994 (Trp64Arg) associates significantly with bodyweight elevation and dyslipidaemias in Saudis but not rs1801253 (Arg389Gly) polymorphism in ARDB1. AB - BACKGROUND: In some populations, obesity and body weight related disorders show a correlation with polymorphisms in three subtypes of beta-adrenoceptor (beta1, beta2, and beta3) [ADRB1, ADRB2 and ADRB3] genes. We scanned for the polymorphism of Arg389Gly (rs1801253) in ADRB1 and Trp64Arg (rs4994) in ADRB3 genes in Saudi population to determine association, if any, of these polymorphisms with obesity and related disorders. METHODS: We studied 329 non-related adults (33.1% men and 66.9% women), aged 18-36 years. Anthropometric measurements were recorded, and Body mass index (BMI) and waist/hip ratio were calculated; leptin, insulin, lipidogram, and glucose concentrations were determined. ADRB1 and ADRB3 polymorphisms (Arg389Gly and Trp64Arg, respectively) were screened by DNA sequencing. The subjects were divided into three groups according to BMI: normal weight (BMI < 25 kg/m2), overweight (BMI >=25.1-29.9 kg/m2) subjects, and obese (>=30 kg/m2). RESULTS: In the age-matched groups of the normal weight, overweight and obese male and female subjects, all anthropometric parameters were found to be significantly higher, and in the obese group, all biochemical parameters were significantly elevated compared to the normal weight controls. The allelic frequency of Gly389 ADRB1 did not differ amongst the three groups, whereas the frequency of Arg64 of ADRB3 gene was significantly higher in the overweight and obese subjects, compared with the normal weight subjects. In addition, subjects carrying Arg64 allele regardless of their BMI had a greater waist and hip circumference, W/H ratio, plasma cholesterol, triglyceride, LDL, leptin, insulin, and glucose level compared to those with the wild-type Trp allele. CONCLUSION: The results of this study have shown a significant association between the Trp64Arg polymorphism in ADRB3 gene and the development of overweight and obesity in Saudi populations. It also has an influence on the levels of lipid, insulin, leptin, and glucose, whereas, Arg389Gly polymorphism in ADRB1 is not associated with overweight, obesity or dyslipidaemias in Saudis.

AB - BACKGROUND: Avian pathogenic Escherichia coli (APEC) are causative agent of extraintestinal infections, collectively known as colibacillosis, which results significant losses in poultry industries. The extraintestinal survival of E. coli is facilitated by numerous virulence factors which are coded by virulence genes. This study was conducted to find out the pattern of antibiotic resistance and virulence genes content in the APEC strains isolated from broiler chickens at National Avian Disease Investigation Laboratory and Veterinary Teaching Hospital, Rampur, Chitwan, Nepal. RESULTS: A total of 50 E. coli strains were isolated from 50 colibacillosis suspected broiler chickens. Out of 50 isolates of E. coli, 47 (94%) showed resistant to three or more antimicrobials. The highest levels (22%) of multidrug-resistant E. coli were observed for five different types of antimicrobials. Antibiogram profiles of 50 E. coli strains showed the maximum resistance to ampicillin (98%), followed by co-trimoxazole (90%), and doxycycline (62%). The highest intermediate resistance was shown by colistin (50%) and the highest sensitivity was against amikacin (84%), followed by nitrofurantoin (55%). Based on the genetic criteria, 45 (90%) E. coli isolates were considered as pathogenic (APEC) which contained more than five virulence genes. Out of total APEC genes detected, we found the combination of iss, iucD, hlyF, ompT, iroN, and iutA genes were mostly associated with the APEC and additionally, to some lesser extent irp2, papC, Cva/cvi, and tsh genes showed the critical role for virulent traits of APEC strains. CONCLUSION: In this study, high prevalent of antimicrobial resistant pattern was found with avian pathogenic E. coli strains isolated from broiler chickens. To our knowledge, this is the first molecular analysis which confirmed the prevalence of APEC strains in poultry sector in Nepal. These finding suggest the need of surveillance and intervention system to control misuse of antibiotics and APEC outbreak in the poultry farm. PMID- 29587769 TI - Circulating osteopontin and its association with liver fat content in non-obese women with polycystic ovary syndrome: a case control study. AB - BACKGROUND: Osteopontin (OPN) plays an important role in inflammatory processes and insulin resistance. Polycystic ovary syndrome (PCOS) is a reproductive metabolic disease associated with insulin resistance and metabolic abnormalities, including high levels of liver fat content (LFC). The objective of this study was to explore whether circulating OPN independently contributes to elevated LFC in non-obese PCOS patients. METHODS: This study included 61 non-obese PCOS patients and 56 age-matched healthy women from Shanghai, China. After an overnight fast, all participants underwent anthropometric measurements, oral glucose tolerance tests, lipid profile and sex hormone measurements. Quantitative measurement of LFC by ultrasonography was performed. OPN concentrations were measured using ELISA. An independent samples t-test and the Mann-Whitney U test were performed to compare variables between the two groups; one-way ANOVA and Kruskal-Wallis test were performed to compare four subgroups of patients. Correlations were determined by Spearman's correlation tests. Stepwise multiple linear regression analyses were performed to assess for independent contributors. A receiver operating characteristic curve with the maximum Youden index was calculated for the optimal cut-off value. RESULTS: In non-obese PCOS women, circulating OPN levels were increased in the subgroups with a higher body mass index (BMI) and free androgen index (FAI), and the LFC levels were increased in the elevated OPN subgroups. Moreover, increased OPN was associated with increased FAI and LFC in PCOS women, and the association between OPN and LFC was independent of triglyceride, HOMA-IR and FAI after adjusting for PCOS status in all participants. OPN combined with FAI and hsCRP may better predict NAFLD than WHR in this study cohort. However, there was no significant difference in circulating OPN levels between non-obese PCOS and normal control women. CONCLUSIONS: Increased OPN levels may be related to FAI and elevated LFC in non-obese women with PCOS. PMID- 29587770 TI - Powdered black cumin seeds strongly improves serum lipids, atherogenic index of plasma and modulates anthropometric features in patients with Hashimoto's thyroiditis. AB - BACKGROUND: Hashimoto's thyroiditis is associated with serious alterations in serum lipids and glucose homeostasis. The aims of the current study were to evaluate the effect of powdered Nigella sativa on serum lipids, glucose homeostasis and anthropometric variables in patients with Hashimoto's thyroiditis. METHODS: Forty patients with Hashimoto's thyroiditis, aged between 22 and 50 years old, participated in the trial and were randomly allocated into two groups of intervention and control receiving powdered Nigella sativa or placebo daily for 8 weeks. Serum lipids, glucose homeostasis, and anthropometric variables were evaluated at baseline and after intervention. RESULTS: Treatment with Nigella sativa significantly reduced body weight and body mass index (BMI). Serum concentrations of low density lipoprotein cholesterol (LDL) and triglyceride (TG) also decreased in Nigella sativa-treated group after 8 weeks; while serum high density lipoprotein cholesterol (HDL) significantly increased after treatment with Nigella sativa (P < 0.05). None of these changes had been observed in placebo treated group. Serum Nesfatin-1 concentrations was in inverse relationship with serum triglyceride (TG) (r = - 0.31, P = 0.04). CONCLUSIONS: Giving attention to the potent beneficial effects of powdered black cumin seeds in improving serum lipid profile and anthropometric features in patients with Hashimoto's thyroiditis, this medicinal plant could be considered as a beneficial herbal supplement alongside with the disease- specific medications including Levothyroxine in management of Hashimoto's thyroiditis- related metabolic abnormalities.

PMID- 29587771 TI - Treatment of intraoperatively detected peritoneal carcinomatosis of colorectal origin with cytoreductive surgery and intraperitoneal chemotherapy. AB - BACKGROUND: Diagnosis of peritoneal carcinomatosis (PC) may be missed by preoperative imaging. We are presenting our experience with incidentally detected PC of colorectal origin treated with cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) at the same operation. METHODS: Between January 2010 and September 2016, 19 patients underwent CRS and IPC due to incidentally detected PC of colorectal origin. Data were analyzed from a prospectively collected database. RESULTS: The median age was 59 (29-78). In three patients, PC was diagnosed during emergency surgery. The primary tumor was located in the rectum (three patients; one with recurrent disease), left colon (9 patients), and right colon (7 patients). All patients underwent CRS and IPC, and one patient operated laparoscopically. Median peritoneal cancer index (PCI) was 5 (range, 3-14), and complete cytoreduction (CC-0) was achieved in 14 patients. After CRS, 8 patients received early postoperative intraperitoneal chemotherapy (EPIC), 7 patients received hyperthermic intraperitoneal chemotherapy (HIPEC), and 4 patients received both HIPEC and EPIC. The median hospital stay was 9 (6 29) days. Postoperative complications occurred in 6 patients. There was no postoperative mortality. Median follow-up was 40.2 (12-94) months. Five-year overall survival was 63.2%. Estimated mean survival time is longer in patients who underwent complete cytoreduction compared to patients having CC-1 or CC-2 cytoreduction (87.7 vs. 20.3 months; p < 0.001). CONCLUSION: Cytoreductive surgery and IPC can be performed safely in patients with intraoperatively detected incidental PC of colorectal origin. PMID- 29587773 TI - CalliSpheres drug-eluting beads versus lipiodol transarterial chemoembolization in the treatment of hepatocellular carcinoma: a short-term efficacy and safety study. AB - BACKGROUND: The present study aimed to evaluate the short-term efficacy and safety of drug-eluting beads transarterial chemoembolization (DEB-TACE) with CalliSpheres Beads loaded with doxorubicin (DOX) in the treatment of Chinese patients with hepatocellular carcinoma (HCC) compared to conventional TACE (cTACE). METHODS: A total of 54 patients with HCC treated by TACE from June 2016 to February 2017 were retrospectively analyzed. These included 24 cases in the DEB-TACE group and 30 cases in the cTACE group. The clinical efficacy, tumor recurrence rate, and complications were compared between the two groups. Furthermore, liver function tests and alpha-feto protein levels were compared between the two groups before and at 1 week and 1 month after interventional treatment. RESULTS: There were no significant differences in baseline characteristics (p > 0.05). Tumor response rates and disease control rates in the DEB-TACE group were significantly higher than those in the cTACE group at 3 and 6 months after treatment (p < 0.05). Recurrence rates at 6 months were significantly higher for cTACE compared to DEB-TACE (43.3 vs. 16.7%; p = 0.036). At 1 month, the AFP level in the DEB-TACE group was significantly lower than that in the cTACE group (p = 0.008). At the end of follow-up, four cases in the DEB TACE group and two cases in the cTACE group were treated with salvage surgery after downstaging the disease. Liver function of both groups improved at 1 month. However, alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels in the DEB-TACE group were better than those in the cTACE group (p < 0.05). The incidence of DOX-related complications in the DEB-TACE group was significantly lower than in the cTACE group (p < 0.05). CONCLUSION: The short term efficacy of DEB-TACE is better, and the complication rates are lower compared to cTACE in the treatment of Chinese patients with HCC. However, long term clinical efficacy and survival benefit should be analyzed in future studies. PMID- 29587772 TI - Oxidative stress enhances the expression of IL-33 in human airway epithelial cells. AB - BACKGROUND: Interleukin-33 (IL-33) is a cytokine belonging to the IL-1 family, and its possible involvement in the pathophysiology of COPD and viral-induced exacerbations has been demonstrated. IL-33 has been shown to be increased in the airway epithelial cells from COPD patients, but the regulating mechanism of IL-33 expression in airway epithelial cells remains largely unknown. In the current study, we examined whether oxidative stress, which participates in the pathogenesis of COPD, affects the expression of IL-33 in airway epithelial cells and also evaluated the effect during viral infection. METHODS: The involvement of oxidative stress in the expression of IL-33, and its signal pathway was examined after stimulation with hydrogen peroxide (H2O2), with or without stimulation by polyinosinic-polycytidylic acid [poly (I:C)], a synthetic analogue of dsRNA that mimics viral infection, or rhinovirus infection in NCI-H292 cells and primary human bronchial epithelial cells (HBECs). In addition, the effect of antioxidant, N-acetylcysteine (NAC) in the expression of IL-33 was compared between HBECs from healthy subjects and those from COPD patients. RESULTS: Treatment with H2O2 significantly potentiated IL-33 expression in NCI-H292 cells, and the potentiation was reversed by NAC treatment. Mitogen-activated protein kinase (MAPK) inhibitors, but not nuclear factor-kappa B inhibitors, also significantly decreased the H2O2-potentiated IL-33 expression. In addition, H2O2 significantly potentiated the poly (I:C)- or rhinovirus-stimulated IL-33 expression. In HBECs from healthy subjects, H2O2-potentiated IL-33 expression and its reversal by NAC was also confirmed. Under the condition without H2O2-stimulation, treatment with NAC significantly decreased the expression of IL-33 in HBECs from COPD patients, but not in those from healthy subjects. CONCLUSIONS: These results demonstrate that oxidative stress involves in the expression of IL-33 in airway epithelial cells via MAPK signal pathway and it augments IL-33 expression during viral infection. This mechanism may participate in the regulation of IL-33 expression in airway epithelial cells in COPD and the viral-induced exacerbations. Modulation of this pathway could become a therapeutic target for viral-induced exacerbations of COPD. PMID- 29587774 TI - Detecting spatio-temporal mortality clusters of European countries by sex and age. AB - BACKGROUND: Mortality decreased in European Union (EU) countries during the last century. Despite these similar trends, there are still considerable differences in the levels of mortality between Eastern and Western European countries. Sub group analysis of mortality in Europe for different age and sex groups is common, however to our knowledge a spatio-temporal methodology as in this study has not been applied to detect significant spatial dependence and interaction with time. Thus, the objective of this paper is to quantify the dynamics of mortality in Europe and detect significant clusters of mortality between European countries, applying spatio-temporal methodology. In addition, the joint evolution between the mortality of European countries and their neighbours over time was studied. METHODS: The spatio-temporal methodology used in this study takes into account two factors: time and the geographical location of countries and, consequently, the neighbourhood relationships between them. This methodology was applied to 26 European countries for the period 1990-2012. RESULTS: Principally, for people older than 64 years two significant clusters were obtained: one of high mortality formed by Eastern European countries and the other of low mortality composed of Western countries. In contrast, for ages below or equal to 64 years only the significant cluster of high mortality formed by Eastern European countries was observed. In addition, the joint evolution between the 26 European countries and their neighbours during the period 1990-2012 was confirmed. For this reason, it can be said that mortality in EU not only depends on differences in the health systems, which are a subject to national discretion, but also on supra-national developments. CONCLUSIONS: This paper proposes statistical tools which provide a clear framework for the successful implementation of development public policies to help the UE meet the challenge of rethinking its social model (Social Security and health care) and make it sustainable in the medium term. PMID- 29587775 TI - New forms of development: branding innovative ideas and bidding for foreign aid in the maternal and child health service in Nepal. AB - BACKGROUND: Nepal has been receiving foreign aid since the early 1950s. Currently, the country's health care system is heavily dependent on aid, even for the provision of basic health services to its people. Globally, the mechanism for the dispersal of foreign aid is becoming increasingly complex. Numerous stakeholders are involved at various levels: donors, intermediary organisations, project-implementing partners and the beneficiaries, engaging not only in Nepal but also globally. To illustrate how branding and bidding occurs, and to discuss how this process has become increasingly vital in securing foreign aid to run MCH activities in Nepal. METHOD: This paper is based on a qualitative study. The data collection method includes Key Informant Interviews, the review of relevant policy documents and secondary data, and finally field observation visits to four maternal and child health (MCH) projects, currently funded by foreign aid. Through these methods we planned to gain a comprehensive understanding of the aid dispersing mechanism, and the aid-securing strategies, used by organisations seeking funds to provide MCH services in Nepal. RESULTS: Study findings suggest that foreign aid for the provision of MCH services in Nepal is channeled increasingly to its beneficiaries, not through the Government system, but rather via various intermediary organisations, employing branding and bidding processes. These organisations adapt commercial models, seeking to justify their 'cost effectiveness'. They argue that they are 'yielding good value for money', with short-term target oriented projects. This ethos is evident throughout the aid dispersing chain. Organisations use innovative ideas and intervention packages, branded internationally and nationally, and employ the appropriate language of commerce in their bid to secure funds. The paper raises an important question as to whether the current mechanisms of channeling foreign aid in the MCH sector, via intermediary organisations, can actually be cost-effective, given the complex bureaucratic processes involved. CONCLUSIONS: The study findings are very important, for Nepal's development in particular, and for international development in general. The paper concludes by recommending strongly that foreign aid should concentrate on supporting and strengthening the national government system. Complex bureaucratic process must be minimised and streamlined in order to provide quality care to the beneficiaries. PMID- 29587776 TI - Improved prediction of gestational hypertension by inclusion of placental growth factor and pregnancy associated plasma protein-a in a sample of Ghanaian women. AB - BACKGROUND: We assessed whether adding the biomarkers Pregnancy Associated Plasma Protein-A (PAPP-A) and Placental Growth Factor (PlGF) to maternal clinical characteristics improved the prediction of a previously developed model for gestational hypertension in a cohort of Ghanaian pregnant women. METHODS: This study was nested in a prospective cohort of 1010 pregnant women attending antenatal clinics in two public hospitals in Accra, Ghana. Pregnant women who were normotensive, at a gestational age at recruitment of between 8 and 13 weeks and provided a blood sample for biomarker analysis were eligible for inclusion. From serum, biomarkers PAPP-A and PlGF concentrations were measured by the AutoDELFIA immunoassay method and multiple of the median (MoM) values corrected for gestational age (PAPP-A and PlGF) and maternal weight (PAPP-A) were calculated. To obtain prediction models, these biomarkers were included with clinical predictors maternal weight, height, diastolic blood pressure, a previous history of gestational hypertension, history of hypertension in parents and parity in a logistic regression to obtain prediction models. The Area Under the Receiver Operating Characteristic Curve (AUC) was used to assess the predictive ability of the models. RESULTS: Three hundred and seventy three women participated in this study. The area under the curve (AUC) of the model with only maternal clinical characteristics was 0.75 (0.64-0.86) and 0.89(0.73-1.00) for multiparous and primigravid women respectively. The AUCs after inclusion of both PAPP-A and PlGF were 0.82 (0.74-0.89) and 0.95 (0.87-1.00) for multiparous and primigravid women respectively. CONCLUSION: Adding the biomarkers PAPP-A and PlGF to maternal characteristics to a prediction model for gestational hypertension in a cohort of Ghanaian pregnant women improved predictive ability. Further research using larger sample sizes in similar settings to validate these findings is recommended. PMID- 29587777 TI - An evaluation of South Africa's public-private partnership for the localisation of vaccine research, manufacture and distribution. AB - BACKGROUND: Public-private partnerships (PPPs), widely used as a means of leveraging the skills, expertise and resources of the private sector to mutual advantage, were similarly adopted by South Africa to support public sector delivery. This study has evaluated one such partnership, namely the Biovac Institute, which was established in 2003 to cover vaccine research and development, manufacturing, and supply. The initiative was highly unusual given that it attempted to combine all three aspects in a single PPP. METHODS: The research has followed a concurrent mixed methods approach. In the quantitative study, data for prices and product volumes were extracted from secondary data sources and used to calculate the economic cost and value-for-money of the PPP. Simultaneously, a qualitative study was undertaken in which a number of key stakeholders were interviewed using a semi-structured questionnaire on their perceptions of the PPP's value. RESULTS: The institute earns a premium on the procurement cost of a broad range of vaccines required by the South African National Department of Health for its immunisation programme, the net value of which was US$85.7 million over the period 2010 to 2014. These funds were used to finance the institute's operations, including vaccine research, distribution and quality control. Capital expenditure to support the establishment of facilities for laboratory testing, packaging and labelling, filling, formulation and, finally, active pharmaceutical ingredient manufacture, approximately US$40 million in total, had to be secured through loans and grants. According to the respondents in the qualitative survey, the principal benefit of the PPP has been the uninterrupted supply of vaccines and the ability to respond quickly to vaccine shortages. The main disadvantages appear to have been a slow and ineffectual establishment of a vaccine manufacturing centre and, initially, a limited ability to negotiate highly competitive vaccine prices. CONCLUSIONS: Overall, it is concluded that a positive value-for-money has been achieved and the institute has been of significant public benefit. Relationships of this nature can be used to achieve public health goals, but need to be realistic about timeframes, costs and the limitations of relational governance in ensuring that complex programmatic outcomes are achieved. It is recommended that a more incremental approach, with clearer contractual goals, penalties and incentives, is adopted in attempting initiatives aimed at the localisation of manufacturing technology by leveraging public procurement. PMID- 29587778 TI - HPV genotype determination and E6/E7 mRNA detection for management of HPV positive women. AB - BACKGROUND: Clinical management of HPV positive women is difficult since many of the infections, including high-risk oncogene genotypes (hr-HPV), are transient. Therefore only a limited number of patients have a high-grade lesion and sending all HPV positive women for colposcopy would only increase costs and unnecessary treatment, with serious psychological consequences for patients. The need has emerged to identify other HPV related markers able to correctly detect women with a high-risk of developing high-grade lesions. Genotyping and the search for E6/E7 mRNA are among the possible candidates. METHODS: The study was carried out by means of an observational analysis of the data relative to 674 HR-HPV positive women who we had observed from January 2013 to June 2015; the data had been gathered in a database at the HPV Center of the University Hospital of Catania, Italy. Women were considered eligible for this study if the following data was present in the database: Pap TEST, histologic evaluation, HPV TEST and E6/E7 mRNA detection. We calculated the Odds Ratio (OR) of woman who were mRNA positive, with CIN2+ lesions, and Odds Ratio of HPV16 positive women. RESULTS: Transcripts were detected in 23.6% (69/292) of the women with CIN1 and in 97.2% (210/220) of those with CIN2 + . Regarding genotyping, the 81,8% (180/220) of the women with CIN2+ had genotype 16, while only 18.1% (40/220) had genotype 18, 31, 33, 45. We calculated the OR in the group of HPV16 women with CIN2+ (OR = 4.62; 95% CI = 3.13 to 6.82), this value increased (OR = 106.12; 95% CI = 53.71 to 209.69) in women with CIN2+ and positive mRNA. DISCUSSION: The presence of the HPV16 genotype in our study was associated with a risk 5 times greater of developing a high-grade lesion (CIN2+) (OR = 4.62 95% CI:3.13-6.82); this supports the hypothesis that it would be opportune to have targeted protocols for the management of HPV 16 positive women. The results showed that there was an association between E6/E7 mRNA expression and histology (OR = 106.12; 95% CI = 53.71 to 209.69). The E6/E7 mRNA test showed a higher prevalence of E6 and E7 transcripts in patients with higher-grade lesions. CONCLUSION: The results of this study suggest that the HPV genotype determination and E6/E7 mRNA detection would find an important application for management of HPV positive women. PMID- 29587779 TI - A novel cardiovirus in wild rats. AB - BACKGROUND: Cardioviruses cause severe illnesses in rodents and humans. In recent years, novel cardioviruses have been frequently found, which promoted further studies of the genetic diversity of cardioviruses. Using viral metagenomics, we genetically characterized a novel cardiovirus (named SX1) from wild rat feces. The genomic structure of SX1 shared similar features with those of the Theiler's murine encephalomyelitis viruses, including a leader protein, four structural proteins and seven non-structural proteins. Phylogenetic analysis based on both structural proteins and non-structural proteins coding regions showed that SX1 was formed into a separate branch, being located between the branches of Theiler's murine encephalomyelitis viruses and Thera viruses. Variable resides presented in the Ser/Thr rich domain of L protein, VP1 loops, and VP2 puffs distinguished SX1 from Theiler's murine encephalomyelitis viruses, suggesting the different antigenicity and pathogenicity of SX1. PMID- 29587780 TI - Genotype-specific and cross-reactive neutralizing antibodies induced by dengue virus infection: detection of antibodies with different levels of neutralizing activities against homologous and heterologous genotypes of dengue virus type 2 in common marmosets (Callithrix jacchus). AB - BACKGROUND: A vaccine against all four dengue virus (DENV) serotypes includes the formulation of one genotype of each serotype. Although genetic similarities among genotypes within a serotype are higher as compared to those among serotypes, differences in the immunogenicity of the included genotypes would be a critical issue in maximizing successful dengue vaccine development. Thus, we determined the neutralizing antibody responses against three genotypes of dengue virus serotype 2 (DENV-2), namely Cosmopolitan, Asian I, and Asian/American, after primary and secondary inoculation with DENV-2 in a dengue animal model, the common marmoset (Callithrix jacchus). METHODS: A total of fifty-four plasma samples were obtained from thirty-four marmosets that were inoculated with clinically-isolated DENV strains or DENV candidate vaccines, were used in this study. Plasma samples were obtained from marmosets after primary inoculation with DENV-2 infection, secondary inoculation with homologous or heterologous genotypes, and tertiary inoculation with heterologous DENV. Neutralizing antibody titers against DENV-2 (Cosmopolitan, Asian I, and Asian/American genotypes) and DENV-1 were determined using a conventional plaque reduction neutralization assay. RESULTS: In marmosets that were inoculated with the Cosmopolitan genotype in primary infection, neutralizing antibody neutralized 3 genotypes, and the titers to Asian I genotype were significantly higher than those to homologous Cosmopolitan genotype. After secondary DENV-2 infection with heterologous genotype (Asian I in primary and Asian/American in secondary), neutralizing antibody titers to Asian/American genotype was significantly higher than those against Cosmopolitan and Asian I genotypes. Following tertiary infection with DENV-1 following DENV-2 Asian I and Cosmopolitan genotypes, neutralizing antibody titers to Asian/American were also significantly higher than those against Cosmopolitan and Asian I genotypes. CONCLUSION: The present study demonstrated that different levels of neutralizing antibodies were induced against variable DENV-2 genotypes after primary, secondary and tertiary infections, and that neutralizing antibody titers to some heterologous genotypes were higher than those to homologous genotypes within a serotype. The results indicate that heterogeneity and homogeneity of infecting genotypes influence the levels and cross-reactivity of neutralizing antibodies induced in following infections. The results also suggest that certain genotypes may possess advantage in terms of breakthrough infections against vaccination. PMID- 29587781 TI - Ossifying Fibromyxoid tumor of soft parts in head and neck: case report and literature review. AB - BACKGROUND: Ossifying fibromyxoid tumor of soft parts (OFMT), is a rare but morphologically distinctive neoplasm of uncertain histogenesis that most frequently affects middle-aged male adults. Clinically, it usually presents as a slowly enlarging, small, circumscribed mass, which in most cases is painless. OFMT is most frequently found within the subcutaneous tissues of extremities or trunk, and rarely in the oral/head and neck region. We present an unusual case of this tumor in the submandibular region, and, based on the current medical literatures this is probably the first case described in this anatomical location. CASE PRESENTATION: A 32-year-old male presented to our outpatient clinic with a right submandibular mass with 1-year of evolution. Excisional biopsy showed that it was characterized by ossification along the periphery of the lesion. The neoplastic cells were spindle-like with scant eosinophilic cytoplasm. These cells were arranged with uniform cell-to-cell space in a fibromyxoid stroma. Small and large clusters of calcifications were present within the tumor. Immunohistochemically, the case showed positive staining of S 100 protein, vimentin, nestin, calponin, SMA, GFAF, desmin, INI-1, caldesmon, and CD34. It also showed negative staining of CK, CK7, CK8/18, NF, and EMA. About 2% of neoplastic cells showed positive staining of Ki67. Based on these features, the final pathological diagnosis was OFMT. CONCLUSIONS: It is hoped that a greater understanding of OFMT in the head and neck region will avoid potential misdiagnosis, and contribute to determining the correct management, which appears to be complete surgical excision with close follow-up for recurrence surveillance. PMID- 29587782 TI - Knowledge-based IMRT planning for individual liver cancer patients using a novel specific model. AB - BACKGROUND: The purpose of this work is to benchmark RapidPlan against clinical plans for liver Intensity-modulated radiotherapy (IMRT) treatment of patients with special anatomical characteristics, and to investigate the prediction capability of the general model (Model-G) versus our specific model (Model-S). METHODS: A library consisting of 60 liver cancer patients with IMRT planning was used to set up two models (Model-S, Model-G), using the RapidPlan knowledge-based planning system. Model-S consisted of 30 patients with special anatomical characteristics where the distance from planning target volume (PTV) to the right kidney was less than three centimeters and Model-G was configurated using all 60 patients in this library. Knowledge-based IMRT plans were created for the evaluation group formed of 13 patients similar to those included in Model-S by Model-G, Model-S and manually (M), named RPG-plans, RPS-plans and M-plans, respectively. The differences in the dose-volume histograms (DVHs) were compared, not only between RP-plans and their respective M-plans, but also between RPG plans and RPS-plans. RESULTS: For all 13 patients, RapidPlan could automatically produce clinically acceptable plans. Comparing RP-plans to M-plans, RP-plans improved V95% of PTV and had greater dose sparing in the right kidney. For the normal liver, RPG-plans delivered similar doses, while RPS-plans delivered a higher dose than M-plans. With respect to RapidPlan models, RPS-plans had better conformity index (CI) values and delivered lower doses to the right kidney V20Gy and maximizing point doses to spinal cord, while delivering higher doses to the normal liver. CONCLUSION: The study shows that RapidPlan can create high-quality plans, and our specific model can improve the CI of PTV, resulting in more sparing of OAR in IMRT for individual liver cancer patients. PMID- 29587783 TI - Worldwide use of the first set of physical activity Country Cards: The Global Observatory for Physical Activity - GoPA! AB - BACKGROUND: The work of The Global Observatory for Physical Activity-GoPA! is the first global effort to compile standardized country-level surveillance, policy and research data for physical activity in order to better understand how countries and regions address promoting physical activity. GoPA! developed standardized country-specific physical activity profiles ("Country Cards") to summarize country-level data through 2013. The aim of this study was to assess use of the Country Cards, identify the factors associated with their use, and develop recommendations for supporting country-level physical activity promotion. METHODS: Cross sectional internet-based survey conducted between August-October 2016. Target study participants were national physical activity leaders and advocates in academia, government and practice from the GoPA! countries, and members of the International Society of Physical Activity and Health. A Country Card use composite score was created based on the diversity and frequency of use. Statistical analyses on the associations between the composite score and respondent characteristics, country characteristics, barriers and opinions were conducted (including descriptive analyses and a logistic regression with robust standard errors). RESULTS: One hundred forty three participants from 68 countries completed the survey. Use of the Country Cards was associated with being part of the GoPA! network, knowing about the Country Cards, and on the stage of country capacity for physical activity promotion. Country Card knowledge varied by country income group, region and the country specific context. More diverse and frequent use of the cards (highest tertile of the composite score for use) was associated with: 1. Being a country contact vs general participant (OR 18.32-95% CI 5.63-59.55, p = 0.002), and 2. Collaborating with a government representative working in NCDs on a monthly or more frequent contact vs less frequent contact (OR 3.39-95% CI 1.00-11.54, P < 0.05). CONCLUSIONS: For the Country Cards to have a broader impact, GoPA! will need to widen its reach beyond the academic sector. With further refinement of the cards, and training in their implementation, they could be an important tool for advancing country capacity for contextually relevant strategies, actions and timelines for PA promotion. PMID- 29587784 TI - Mesh-reinforced pancreaticojejunostomy versus conventional pancreaticojejunostomy after pancreaticoduodenectomy: a retrospective study of 126 patients. AB - BACKGROUND: Pancreatic fistula is a major cause of morbidity and mortality after pancreaticoduodenectomy. The aim of this study is to compare the safety and efficacy of a newly developed technique, namely mesh-reinforced pancreaticojejunostomy, in comparison with the conventional use of pancreaticojejunostomy after undergoing a pancreaticoduodenectomy. METHODS: Data was collected from regarding 126 consecutive patients, who underwent the mesh reinforced pancreaticojejunostomy or conventional pancreaticojejunostomy, after standard pancreaticoduodenectomy by one group of surgeons, between the time period of 2005 and 2016. This data was collected retrospectively. Surgical parameters and perioperative outcomes were compared between these two groups. RESULTS: A total of 65 patients received mesh-reinforced pancreaticojejunostomy and 61 underwent conventional pancreaticojejunostomy. There were no substantial differences in surgical parameters, mortality, biliary leakage, delayed gastric emptying, gastrojejunostomy leakage, intra-abdominal fluid collection, postpancreatectomy hemorrhage, reoperation, and the total hospital costs between the two groups. Pancreatic fistula rate (15 versus 34%; p = 0.013), overall surgical morbidity (25 versus 43%; p = 0.032), and length of hospital stay (18 +/ 9 versus 23 +/- 12 days; p = 0.016) were significantly reduced after mesh reinforced pancreaticojejunostomy. Multivariate analysis of the postoperative pancreatic fistula revealed that the independent factors that were highly associated with pancreatic fistula were a soft pancreatic texture and the type of conventional pancreaticojejunostomy. CONCLUSIONS: This retrospective single center study showed that mesh-reinforced pancreaticojejunostomy appears to be a safe technique for pancreaticojejunostomy. It may reduce pancreatic fistula rate and surgical complications after pancreaticoduodenectomy. TRIAL REGISTRATION: This research is waivered from trial registration because it is a retrospective analysis of medical records. PMID- 29587785 TI - Trigger wrist caused by avascular necrosis of the capitate: a case report. AB - BACKGROUND: Trigger wrist is a rare condition first described by Marti in 1960, and various causes have been reported. The condition mostly occurs with finger flexion and extension, and rarely with flexion and extension of the wrist itself. Avascular necrosis of the capitate is also a rare condition, first described by Jonsson in 1942. While some reports of this condition have been published, little is known about its etiology. Therefore, no established treatment exists. We report a case of trigger wrist caused by avascular necrosis of the capitate. CASE PRESENTATION: A 16-year-old right-handed male who was a high school handball player was referred to our department from a nearby hospital 5 months after the onset of pain in the dorsal aspect of the right wrist, with an unknown cause. At the previous hospital, imaging findings led to a diagnosis of avascular necrosis of the capitate, and conservative treatment with a wrist brace did not improve the pain. At the initial visit to our department, the patient was noted to have a painful trigger wrist that was brought on by wrist flexion and extension. Preoperative imaging findings led to a diagnosis of trigger wrist caused by capitolunate instability secondary to avascular necrosis of the capitate. We performed a partial excision of the proximal capitate with tendon ball interposition. Two years after surgery, the patient's clinical outcome was favorable, with no recurrence of wrist pain or triggering. CONCLUSIONS: Both trigger wrist and avascular necrosis of the capitate are rare disorders. When a patient presents with painful triggering at the wrist, surgeons must bear in mind that avascular necrosis of the capitate may result in this phenomenon. We recommend partial excision of the proximal capitate with tendon ball interposition for the treatment of this lesion. PMID- 29587786 TI - Effects of the S42 residue of the H1N1 swine influenza virus NS1 protein on interferon responses and virus replication. AB - BACKGROUND: The influenza A virus non-structural protein 1 (NS1) is a multifunctional protein that plays an important role in virus replication, virulence and inhibition of the host antiviral immune response. In the avian influenza virus or human influenza virus, specific amino acids of NS1 have been shown to be important for the virus to antagonize host antiviral defenses and promote viral replication. However, little research has been reported regarding the swine influenza virus (SIV) NS1 protein. METHODS: To study the effects of the key amino acids of NS1, we rescued NS1 mutants (S42P, D92E, and S42P/D92E) of the A/swine/Shanghai/3/2014(H1N1) strain and compared their replication ability and cytokine production as well as the intracellular localization in cultured cells. RESULTS: We found that the S42P and D92E mutation displayed no changes on NS1 nuclear localization. The S42P (but not D92E) mutation suppressed protein synthesis and reduced virus growth properties, and there was an inability to antagonize host cell interferon production and IRF3 activation, which led to high levels of IFN-alpha and IFN-beta production. CONCLUSION: We conclude that the S42 residue of the NS1 of the A/swine/Shanghai/3/2014(H1N1) strain is the key amino acid in regulating the host IFN response by blocking the activation of IRF3 and thus facilitates virus replication. PMID- 29587787 TI - Pediatric Langerhans cell histiocytosis of the temporal bone: clinical and imaging studies of 27 cases. AB - BACKGROUND: We aimed to evaluate the clinical and imaging presentations of Langerhans cell histiocytosis (LCH) in the pediatric temporal bone. METHODS: This retrospective study included 27 pediatric cases with pathological confirmed LCH of the temporal bone. The clinical and imaging features of the cases were analyzed. The involvement of ossicular chain and otic capsule was also evaluated. RESULTS: A total of 38 lesions (27 cases) with 11 bilateral involvement were identified. For the 27 cases, the most common complaint was periauricular swelling (12/27, 44.4%), followed by otorrhea (9/27, 33.3%) and otalgia (5/27, 18.2%). The mastoid process was the most common involved subsite (31/38, 81.6%) among the 38 lesions. Ten (26.3%, 10/38) lesions belonged to the group of the diffuse involvement, 22 (57.9%, 22/38) were divided into the group of partial involvement and six (15.8%,6/38) localized lesions with punched-out appearance. Erosion of ossicular chains and otic capsule were found in three and seven lesions respectively. CONCLUSION: The results indicate that the most common subsite for LCH of the pediatric temporal bone was the mastoid process. The location and extent of pediatric LCH of the temporal bone varied a lot between each other. The ossicular chains usually remain intact and the erosion of otic capsule can occur in some lesions. PMID- 29587788 TI - Socioeconomic inequalities in cardiometabolic control in patients with type 2 diabetes. AB - BACKGROUND: The aim of this study was to determine if the achievement of control targets in patients with type 2 diabetes was associated with personal socioeconomic factors and if these associations were sex-dependent. METHODS: This cross-sectional, population-based study was conducted in Spain. Glycated haemoglobin (HbA1c) level and other clinical parameters were obtained from electronic primary care records (n = 32,638 cases). Socioeconomic status was determined using education level and yearly income. Among patients, having their HbA1c level checked during the previous year was considered as an indirect measure of the process of care, whereas tobacco use and clinical parameters such as HbA1c, low-density lipoprotein cholesterol (LDL-c) and blood pressure (BP) were considered intermediate control outcomes. General linear mixed effect models were used to assess associations. RESULTS: The achievement of metabolic and cardiovascular control targets in patients with type 2 diabetes was associated with educational level and income, and socioeconomic gradients differed by sex. The probability of having had an HbA1c test performed in the previous year was higher in patients with lower education levels. Patients in the lowest income and education level categories were less likely to have reached the recommended HbA1c level. Males in the lowest education level categories were less likely to be non smokers or to have achieved the blood pressure targets. In contrast, patients within the low income categories had a higher probability of reaching the recommended LDL-c level. CONCLUSIONS: Our results suggest the presence of socioeconomic inequalities in the achievement of cardiovascular and metabolic control that differed in direction and magnitude depending on the measured outcome and sex of the patient. These findings may help health professionals focus on high-risk individuals to decrease health inequalities. PMID- 29587790 TI - Inhibition of HIV early replication by the p53 and its downstream gene p21. AB - BACKGROUND: The tumor suppressor gene p53 has been found to suppress HIV infection by various mechanisms, but the inhibition of HIV at an early stage of replication by host cell p53 and its downstream gene p21 has not been well studied. METHOD: VSV-G pseudotyped HIV-1 or HIV-2 viruses with GFP or luciferase reporter gene were used to infect HCT116 p53+/+ cells, HCT116 p53-/- cells and hMDMs. The infections were detected by flow cytometry or measured by luciferase assay. Reverse transcription products were quantified by a TaqMan real time PCR. siRNA knockdown experiments were applied to study potential roles of p53 and p21 genes in their restriction to HIV infection. Western blot experiments were used to analyze changes in gene expression. RESULTS: The infection of HIV-1 was inhibited in HCT116 p53+/+ cells in comparison to HCT116 p53-/- cells. The fold of inhibition was largely increased when cell cycle switched from cycling to non cycling status. Further analysis showed that both p53 and p21 expressions were upregulated in non-cycling HCT116 p53+/+ cells and HIV-1 reverse transcription was subsequently inhibited. siRNA knockdown of either p53 or p21 rescued HIV-1 reverse transcription from the inhibition in non-cycling HCT116 p53+/+ cells. It was identified that the observed restrictions by p53 and p21 were associated with the suppression of RNR2 expression and phosphorylation of SAMHD1. These observations were confirmed by using siRNA knockdown experiments. In addition, p53 also inhibited HIV-2 infection in HCT116 p53+/+ cells and siRNA knockdown of p21 increased HIV-2 infection in hMDMs. Finally the expressions of p53 and p21 were found to be induced in hMDMs shortly after HIV-1 infection. CONCLUSIONS: The p53 and its downstream gene p21 interfere with HIV early stage of replication in non-cycling cells and hMDMs. PMID- 29587789 TI - Rescue and characterization of recombinant cedar virus, a non-pathogenic Henipavirus species. AB - BACKGROUND: Hendra virus and Nipah virus are zoonotic viruses that have caused severe to fatal disease in livestock and human populations. The isolation of Cedar virus, a non-pathogenic virus species in the genus Henipavirus, closely related to the highly pathogenic Hendra virus and Nipah virus offers an opportunity to investigate differences in pathogenesis and receptor tropism among these viruses. METHODS: We constructed full-length cDNA clones of Cedar virus from synthetic oligonucleotides and rescued two replication-competent, recombinant Cedar virus variants: a recombinant wild-type Cedar virus and a recombinant Cedar virus that expresses a green fluorescent protein from an open reading frame inserted between the phosphoprotein and matrix genes. Replication kinetics of both viruses and stimulation of the interferon pathway were characterized in vitro. Cellular tropism for ephrin-B type ligands was qualitatively investigated by microscopy and quantitatively by a split-luciferase fusion assay. RESULTS: Successful rescue of recombinant Cedar virus expressing a green fluorescent protein did not significantly affect virus replication compared to the recombinant wild-type Cedar virus. We demonstrated that recombinant Cedar virus stimulated the interferon pathway and utilized the established Hendra virus and Nipah virus receptor, ephrin-B2, but not ephrin-B3 to mediate virus entry. We further characterized virus-mediated membrane fusion kinetics of Cedar virus with the known henipavirus receptors ephrin-B2 and ephrin-B3. CONCLUSIONS: The recombinant Cedar virus platform may be utilized to characterize the determinants of pathogenesis across the henipaviruses, investigate their receptor tropisms, and identify novel pan-henipavirus antivirals. Moreover, these experiments can be conducted safely under BSL-2 conditions. PMID- 29587791 TI - Sexual and reproductive health behavior and unmet needs among a sample of adolescents living with HIV in Zambia: a cross-sectional study. AB - BACKGROUND: Adolescents living with HIV face challenges, such as disclosure of HIV status, adherence to antiretroviral therapy, mental health, and sexual and reproductive health (SRH). These challenges affect their future quality of life. However, little evidence is available on their sexual behaviors and SRH needs in Zambia. This study aimed at assessing their sexual behaviors and SRH needs and identifying factors associated with marriage concerns and a desire to have children. METHODS: This cross-sectional study was conducted at the University Teaching Hospital from April to July 2014. We recruited 200 adolescents aged 15 19 years who were aware of their HIV-positive status. We collected data on their first and recent sexual behavior, concerns about marriage, and desire to have children. We used the Generalized Linear Model to identify factors associated with having concerns about marriage and desire to have children. We performed thematic analysis with open-ended data to determine their perceptions about marriage and having children in the future. RESULTS: Out of 175 studied adolescents, 20.6% had experienced sexual intercourse, and only 44.4% used condoms during the first intercourse. Forty-eight percent had concerns about marriage, and 87.4% desired to have children. Marriage-related concerns were high among those who desired to have children (adjusted relative risk [ARR] = 2.51, 95% CI = 1.02 to 6.14). Adolescents who had completed secondary school were more likely to desire to have children (ARR = 1.35, 95% CI = 1.07 to 1.71). Adolescents who had lost both parents were less likely to want children (ARR = 0.80, 95% CI = 0.68 to 0.95). Thematic analysis identified that major concerns about future marriage were fear of disclosing HIV status to partners and risk of infecting partners and/or children. The reasons for their willingness to have children were the desire to be a parent, having children as family assets, a human right, and a source of love and happiness. CONCLUSIONS: Zambian adolescents living with HIV are at risk of engaging in risky sexual relationships and have difficulties in meeting needs of SRH. HIV care service must respond to a wide range of needs. PMID- 29587792 TI - Major contribution of the RNA-binding domain of NS1 in the pathogenicity and replication potential of an avian H7N1 influenza virus in chickens. AB - BACKGROUND: Non-structural protein NS1 of influenza A viruses harbours several determinants of pathogenicity and host-range. However it is still unclear to what extent each of its two structured domains (i.e. RNA-binding domain, RBD, and effector domain, ED) contribute to its various activities. METHODS: To evaluate the respective contributions of the two domains, we genetically engineered two variants of an H7N1 low pathogenicity avian influenza virus harbouring amino-acid substitutions that impair the functionality of either domain. The RBD- and ED mutant viruses were compared to their wt- counterpart in vivo and in vitro, notably in chicken infection and avian cell culture models. RESULTS: The double substitution R38A-K41A in the RBD dramatically reduced the pathogenicity and replication potential of the virus, whereas the substitution A149V that was considered to abrogate the IFN-antagonistic activity of the effector domain entailed much less effects. While all three viruses initiated the viral life cycle in avian cells, replication of the R38A-K41A virus was severely impaired. This defect was associated with a delayed synthesis of nucleoprotein NP and a reduced accumulation of NS1, which was found to reach a concentration of about 30 micromol.L- 1 in wt-infected cells at 8 h post-infection. When overexpressed in avian lung epithelial cells, both the wt-NS1 and 3841AA-NS1, but not the A149V NS1, reduced the poly(I:C)-induced activation of the IFN-sensitive chicken Mx promoter. Unexpectedly, the R38A-K41A substitution in the recombinant RBD did not alter its in vitro affinity for a model dsRNA. When overexpressed in avian cells, both the wt- and A149V-NS1s, as well as the individually expressed wt-RBD to a lesser extent, enhanced the activity of the reconstituted viral RNA-polymerase in a minireplicon assay. CONCLUSIONS: Collectively, our data emphasized the critical importance and essential role of the RNA-binding domain in essential steps of the virus replication cycle, notably expression and translation of viral mRNAs. PMID- 29587793 TI - Thriving in scrubs: a qualitative study of resident resilience. AB - BACKGROUND: Physician well-being impacts both doctors and patients. In light of high rates of physician burnout, enhancing resilience is a priority. To inform effective interventions, educators need to understand how resilience develops during residency. METHODS: A qualitative study using grounded theory examined the lived experience of resilience in residents. A cohort of obstetrics and gynecology residents were selected as a purposive, intensity sample.. Eighteen residents in all years of training participated in semi-structured interviews. A three-phase process of open coding, analytic coding and thematic analysis generated a conceptual model for resilience among residents. RESULTS: Resilience among residents emerged as rooted in the resident's calling to the work of medicine. Drive to overcome obstacles arose from personal identity and aspiration to professional ideals. Adversity caused residents to examine and cultivate coping mechanisms. Personal connections to peers and mentors as well as to patients and the work helped buffer the stress and conflicts that present. Resilience in this context is a developmental phenomenon that grows through engagement with uncertainty and adversity. CONCLUSION: Resilience in residents is rooted in personal and professional identity, and requires engagement with adversity to develop. Connections within the medical community, finding personal fulfillment in the work, and developing self-care practices enhance resilience. PMID- 29587794 TI - The relevance of spatial aggregation level and of applied methods in the analysis of geographical distribution of cancer mortality in mainland Portugal (2009 2013). AB - BACKGROUND: Knowledge regarding the geographical distribution of diseases is essential in public health in order to define strategies to improve the health of populations and quality of life. The present study aims to establish a methodology to choose a suitable geographic aggregation level of data and an appropriated method which allow us to analyze disease spatial patterns in mainland Portugal, avoiding the "small numbers problem." Malignant cancer mortality data for 2009-2013 was used as a case study. METHODS: To achieve our aims, we used official data regarding the mortality by all malignant cancer, between 2009 and 2013, and the mainland Portuguese resident population in 2011. Three different spatial aggregation levels were applied: Nomenclature of Territorial Units for Statistics, level III (28 areas), municipalities (278 areas), and parishes (4050 areas). Standardized Mortality Ratio (SMR) and relative risk (RR) were computed with Besag, York and Mollie model (BYM) for the evaluation of geographic patterns of mortality data. We also estimated Global Moran's I, Local Moran's I, and posterior probability (PP) for the spatial cluster analysis. RESULTS: Our results show that the occurrence of lower and higher extreme values of the standardized mortality ratio tend to increase with the decrease of data spatial aggregation. In addition, the number of local clusters is higher at small spatial aggregation levels, although the area of each cluster is generally smaller. Regarding global clustering, data forms clusters at all considered levels. Relative risk (RR) computed by Besag, York and Mollie model, in turn, also shows different results at the municipalities and parishes levels. However, the difference is smaller than the difference obtained by SMR computation. This statement is supported by the coefficient variation values. CONCLUSIONS: Our findings show that the choice of spatial data aggregation level has high importance in the research results, as different aggregation levels can lead to distinct results. In terms of the case study, we conclude that for the period of 2009-2013, cancer mortality in mainland Portugal formed clusters. The most suitable applicable spatial scale and method seemed to be at the municipalities level and Besag, York and Mollie model, respectively. However, further studies should be conducted in order to provide greater support to these results. PMID- 29587795 TI - Clinical outcome after particle therapy for meningiomas of the skull base: toxicity and local control in patients treated with active rasterscanning. AB - BACKGROUND: Meningiomas of the skull base account for 25-30% of all meningiomas. Due to the complex structure of the cranial base and its close proximity to critical structures, surgery is often associated with substantial morbidity. Treatment options include observation, aggressive surgical intervention, stereotactic or conventional radiotherapy. In this analysis we evaluate the outcome of 110 patients with meningiomas of the skull base treated with particle therapy. It was performed within the framework of the "clinical research group heavy ion therapy" and supported by the German Research Council (DFG, KFO 214). METHODS: Between May 2010 and November 2014, 110 Patients with skull base meningioma were treated with particle radiotherapy at the Heidelberg Ion Therapy Center (HIT). Primary localizations included the sphenoid wing (n = 42), petroclival region (n = 23), cavernous sinus (n = 4), sella (n = 10) and olfactory nerve (n = 4). Sixty meningiomas were benign (WHO degrees I); whereas 8 were high-risk (WHO degrees II (n = 7) and degrees III (n = 1)). In 42 cases histology was not examined, since no surgery was performed. Proton (n = 104) or carbon ion (n = 6) radiotherapy was applied at Heidelberg Ion Therapy Center (HIT) using raster-scanning technique for active beam delivery. Fifty one patients (46.4%) received radiotherapy due to tumor progression, 17 (15.5%) after surgical resection and 42 (38.2%) as primary treatment. RESULTS: Median follow-up in this analysis was 46,8 months (95% CI 39,9-53,7; Q1-Q3 34,3-61,7). Particle radiotherapy could be performed safely without toxicity-related interruptions. No grade IV or V toxicities according to CTCAE v4.0 were observed. Particle RT offered excellent overall local control rates with 100% progression-free survival (PFS) after 36 months and 96.6% after 60 months. Median PFS was not reached due to the small number of events. Histology significantly impacted PFS with superior PFS after 5 years for low-risk tumors (96.6% vs. 75.0%, p = 0,02). Overall survival was 96.2% after 60 months and 92.0% after 72 months from therapy. Of six documented deaths, five were definitely not and the sixth probably not meningioma related. CONCLUSION: Particle radiotherapy is an excellent treatment option for patients with meningiomas of the skull base and can lead to long-term tumor control with minimal side effects. Other prospective studies with longer follow up will be necessary to further confirm the role of particle radiotherapy in skull base meningioma. PMID- 29587796 TI - Human papilloma virus correlates of high grade cervical dysplasia in HIV-infected women in Mombasa, Kenya: a cross-sectional analysis. AB - BACKGROUND: Women living with HIV are at increased risk to be co-infected with HPV, persistent high-risk (HR) human papillomavirus (HPV) infection and increased HR HPV viral load, which make them more at risk for cervical cancer. Despite their inherent vulnerability, there is a scarcity of data on potential high risk (pHR) and HR HPV genotypes in HIV- infected women with cervical dysplasia and HPV type specific viral load in this population in Sub Saharan Africa. The aim of this analysis of HIV-infected women was to explore the virological correlates of high-grade cervical dysplasia (CIN 2+) in HIV-infected women, thereby profiling HPV genotypes. METHOD: This analysis assesses baseline data obtained from a cohort study of 74 HIV-infected women with abnormal cytology attending a Comprehensive Care Centre for patients with HIV infection in Mombasa, Kenya. Quantitative real-time PCR was used for HPV typing and viral load. RESULTS: CIN 2 was observed in 16% (12/74) of women, CIN 3 in 23% (17/74), and, invasive cervical carcinoma (ICC) in 1% (1/74) of women. In women with CIN 3+, HPV 16 (44%), HPV 56 (33%), HPV 33 and 53 (HPV 53 (28%) were the most prevalent genotypes. HPV 53 was observed as a stand-alone HPV in one woman with ICC. A multivariate logistic regression adjusting for age, CD4 count and HPV co infections suggested the presence of HPV 31 as a predictor of CIN 2+ (adjusted odds ratio [aOR]:4.9; p = 0.05; 95% (Confidence Interval) [CI]:1.03-22.5). Women with CIN2+ had a significantly higher viral log mean of HPV 16, (11.2 copies/ 10,000 cells; 95% CI: 9.0-13.4) than with CIN 1. CONCLUSION: The high prevalence of HPV 53 in CIN 3 and as a stand-alone genotype in the patient with invasive cervical cancer warrants that its clinical significance be further revisited among HIV-infected women. HPV 31, along with elevated means of HPV 16 viral load were predictors of CIN 2 + . PMID- 29587797 TI - Comparison of efficacy and safety of preoperative Chemoradiotherapy in locally advanced upper and middle/lower rectal cancer. AB - BACKGROUND: We aimed to explore the efficacy and safety profile of preoperative neoadjuvant chemoradiation (NACRT) in locally advanced rectal cancer (LARC) in upper rectum versus middle/lower rectum. METHODS: The study included 173 patients with stage II or III (T2-4b, N0-2b) LARC who underwent NACRT followed by total mesorectal excision (TME) between January 2011 and October 2016. Cox regression, log-rank test, and Kaplan-Meier curves were calculated. RESULTS: Among the 173 patients, 58 had lesions in the upper rectum and 115 patients had lesions in middle/lower rectum. In a median follow-up of 35 months (range, 6-73 months), the 5-year disease-free survival (DFS) and overall survival (OS) were 84% and 88% for the patients with upper rectal cancer and 77% and 68% for those with middle/lower rectal cancer (P = 0.251 and P = 0.058, respectively). The 5-year DFS (P = 0.012) and OS (P = 0.003) were better in the NACRT responders [tumor regression grade (TRG) 0 or 1] compared with nonresponders (TRG 2 or 3). The independent prognostic factor of favorable response to NACRT was the FOLFOX regimen (P = 0.004). CONCLUSIONS: Patients with LARC in the upper rectum who underwent NACRT followed by TME had similar DFS and a trend toward longer OS, compared with those who had middle/lower rectal lesions. Furthermore, FOLFOX may yield superior results than fluoropyrimidine based regimen during NACRT. NACRT might be an alternative option for patients with LARC in the upper rectum as it has a favorable pathological complete response rate and comparable clinical outcomes when compared with patients with LARC in middle/lower rectum. PMID- 29587798 TI - Inhibition of peripheral macrophages by nicotinic acetylcholine receptor agonists suppresses spinal microglial activation and neuropathic pain in mice with peripheral nerve injury. AB - BACKGROUND: Neuro-immune interaction underlies chronic neuroinflammation and aberrant sensory processing resulting in neuropathic pain. Despite the pathological significance of both neuroinflammation-driven peripheral sensitization and spinal sensitization, the functional relationship between these two distinct events has not been understood. METHODS: In this study, we determined whether inhibition of inflammatory macrophages by administration of alpha4beta2 nicotinic acetylcholine receptor (nAChR) agonists improves neuropathic pain and affects microglial activation in the spinal dorsal horn (SDH) in mice following partial sciatic nerve ligation (PSL). Expression levels of neuroinflammatory molecules were evaluated by RT-qPCR and immunohistochemistry, and PSL-induced mechanical allodynia was defined by the von Frey test. RESULTS: Flow cytometry revealed that CD11b+ F4/80+ macrophages were accumulated in the injured sciatic nerve (SCN) after PSL. TC-2559, a full agonist for alpha4beta2 nAChR, suppressed the upregulation of interleukin-1beta (IL 1beta) in the injured SCN after PSL and attenuated lipopolysaccharide-induced upregulation of IL-1beta in cultured macrophages. Systemic (subcutaneous, s.c.) administration of TC-2559 during either the early (days 0-3) or middle/late (days 7-10) phase of PSL improved mechanical allodynia. Moreover, local (perineural, p.n.) administration of TC-2559 and sazetidine A, a partial agonist for alpha4beta2 nAChR, during either the early or middle phase of PSL improved mechanical allodynia. However, p.n. administration of sazetidine A during the late (days 21-24) phase did not show the attenuating effect, whereas p.n. administration of TC-2559 during this phase relieved mechanical allodynia. Most importantly, p.n. administration of TC-2559 significantly suppressed morphological activation of Iba1+ microglia and decreased the upregulation of inflammatory microglia-dominant molecules, such as CD68, interferon regulatory factor 5, and IL-1beta in the SDH after PSL. CONCLUSION: These findings support the notion that pharmacological inhibition of inflammatory macrophages using an alpha4beta2 nAChR agonist exhibit a wide therapeutic window on neuropathic pain after nerve injury, and it could be nominated as a novel pharmacotherapy to relieve intractable pain. PMID- 29587799 TI - HLA alleles modulate EBV viral load in multiple sclerosis. AB - BACKGROUND: The etiopathology of multiple sclerosis (MS) is believed to include genetic and environmental factors. Human leukocyte antigen (HLA) alleles, in particular, are associated with disease susceptibility, whereas Epstein Barr Virus (EBV) infection has long been suspected to play a role in disease pathogenesis. The aim of the present study is to evaluate correlations between HLA alleles and EBV infection in MS. METHODS: HLA alleles, EBV viral load (VL) and serum anti-EBV antibody titers were evaluated in EBV-seropositive MS patients (N = 117) and age- and sex-matched healthy controls (HC; N = 89). RESULTS: Significantly higher DNA viral loads (p = 0.048) and EBNA-1 antibody titer (p = 0.0004) were seen in MS compared to HC. EBV VL was higher in HLA-B*07+ (p = 0.02) and HLA-DRB1*15+ (p = 0.02) MS patients, whereas it was lower in HLA-A*02+ (p = 0.04) subjects. EBV VL was highest in HLA-A*02-/B*07+/DRB1*15+ patients and lowest in HLA-A*A02+/B*07-/DRB1*15- individuals (p < 0.0001). HLA-B*07 resulted the most associated allele to EBV VL after multiple regression analysis considering altogether the three alleles, (p = 0.0001). No differences were observed in anti-EBV antibody titers in relationship with HLA distribution. CONCLUSIONS: Host HLA-B*07 allele influence EBV VL in MS. As HLA-class I molecules present antigens to T lymphocytes and initiate immune response against viruses, these results could support a role for EBV in MS.

AB - BACKGROUND: Hippo/YAP pathway is known to be important for development, growth and organogenesis, and dysregulation of this pathway leads to tumor progression. We and others find that YAP is up-regulated in pancreatic ductal adenocarcinoma (PDAC) and associated with worse prognosis of patients. Activated pancreatic stellate cells (PSCs) forming the components of microenvironment that enhance pancreatic cancer cells (PCs) invasiveness and malignance. However, the role and mechanism of YAP in PDAC tumor-stromal interaction is largely unknown. METHODS: The expression of YAP in Pancreatic cancer cell lines and PDAC samples was examined by Western blot and IHC. The biological role of YAP on cancer cell proliferation, epithelial-mesenchymal transition (EMT) and invasion were evaluated by MTT, Quantitative real-time PCR analysis, Western blot analysis and invasion assay. The effect of YAP on PSC activation was evaluated by PC-PSC co culture conditions and xenograft PDAC mouse model. RESULTS: Firstly, knockdown of YAP inhibits PDAC cell proliferation and invasion in vitro. In addition, YAP modulates the PC and PSC interaction via reducing the production of connective tissue growth factor (CTGF) from PCs, inhibits paracrine-mediated PSC activation under PC-PSC co-culture conditions and in turn disrupts TGF-beta1-mediated tumor stromal interactions. Lastly, inhibiting YAP expression prevents tumor growth and suppresses desmoplastic reaction in vivo. CONCLUSIONS: These results demonstrate that YAP contributes to the proliferation and invasion of PC and the activation of PSC via tumor-stromal interactions and that targeting YAP may be a promising therapeutic strategy for PDAC treatment. PMID- 29587801 TI - Effects of Dangguixu-san on acute lateral ankle sprain: study protocol for a randomized controlled trial. AB - BACKGROUND: Ankle sprain is a common musculoskeletal injury. In Korean medicine, blood stasis is thought to be the main cause of pain and swelling in patients with ankle sprain. Dangguixu-san (DS), a herbal extract, is widely used in Korean medicine for the treatment of traumatic ecchymosis and pain by promoting blood circulation and relieving blood stasis. However, the effects of DS on ankle sprain have not been evaluated in a randomized clinical trial. Here, we describe the protocol for a randomized controlled trial that will evaluate the efficacy and safety of DS for the treatment of ankle sprain. METHODS/DESIGN: In this randomized, double-blinded, placebo-controlled, parallel-arm clinical trial with a 1:1 allocation ratio, participants (n = 48) with acute lateral ankle sprain (ALAS) that occurred within 72 h before enrollment will be randomly assigned to a DS (n = 24) or a placebo (n = 24) group. Both groups will receive acupuncture treatment once a day for 5 days a week (excluding Saturday and Sunday) and the trial medication (DS/placebo capsule) three times a day for seven consecutive days. The primary outcome measure will be pain relief evaluated using a Visual Analog Scale (VAS). Secondary outcome measures will include Foot and Ankle Outcome Scores (FAOS), edema, European Quality of Life Five-Dimension-Five-Level Scale (EQ-5D-5 L) scores, and the number of recurrent ankle sprains. VAS, FAOS, edema, and EQ-5D-5 L scores will be recorded before, at the end of, and at 4 weeks after treatment completion. EQ-5D-5 L scores will be additionally recorded at 26 weeks after treatment completion. The number of recurrent ankle sprains will be recorded at 4, 8, 12, and 26 weeks after treatment completion. DISCUSSION: This study is expected to provide evidence regarding the efficacy, safety, and usefulness of DS for the treatment of ALAS.

PMID- 29587802 TI - Disrespect and abuse of women during the process of childbirth in the 2015 Pelotas birth cohort. AB - BACKGROUND: The disrespect and abuse of women during the process of childbirth is an emergent and global problem and only few studies have investigated this worrying issue. The objective of the present study was to describe the prevalence of disrespect and abuse of women during childbirth in Pelotas City, Brazil, and to investigate the factors involved. METHODS: This was a cross-sectional population-based study of women delivering members of the 2015 Pelotas birth cohort. Information relating to disrespect and abuse during childbirth was obtained by household interview 3 months after delivery. The information related to verbal and physical abuse, denial of care and invasive and/or inappropriate procedures. Poisson regression was used to evaluate the factors associated with one or more, and two or more, types of disrespectful treatment or abuse. RESULTS: A total of 4275 women took part in a perinatal study. During the three-month follow-up, we interviewed 4087 biological mothers with regards to disrespect and abuse. Approximately 10% of women reported having experienced verbal abuse, 6% denial of care, 6% undesirable or inappropriate procedures and 5% physical abuse. At least one type of disrespect or abuse was reported by 18.3% of mothers (95% confidence interval [CI]: 17.2-19.5); and at least two types by 5.1% (95% CI: 4.4 5.8). Women relying on the public health sector, and those whose childbirths were via cesarean section with previous labor, had the highest risk, with approximately a three- and two-fold increase in risk, respectively. CONCLUSIONS: Our study showed that the occurrence of disrespect and abuse during childbirth was high and mostly associated with payment by the public sector and labor before delivery. The efforts made by civil society, governments and international organizations are not sufficient to restrain institutional violence against women during childbirth. To eradicate this problem, it is essential to 1) implement policies and actions specific for this type of violence and 2) formulate laws to promote the equality of rights between women and men, with particular emphasis on the economic rights of women and the promotion of gender equality in terms of access to jobs and education. PMID- 29587803 TI - Sample size implications of mortality definitions in sepsis: a retrospective cohort study. AB - BACKGROUND: Many randomized controlled trials (RCTs) employ mortality at a given time as a primary outcome. There are at least three common ways to measure 90-day mortality: first, all-location mortality, that is, all-cause mortality within 90 days of randomization at any location. Second, ARDSnet mortality is death in a healthcare facility of greater intensity than the patient was in prior to the hospitalization during which they were randomized. Finally, in-hospital mortality is death prior to discharge from the primary hospitalization of randomization. Data comparing the impact of these different measurements on sample size are lacking. We evaluated the extent to which event rates vary by mortality definition. METHODS: This was a retrospective cohort study of 30,691 patients hospitalized at Veterans Affairs (VA) hospitals for sepsis during 2009. 12,727 (41.5%) received care in an ICU setting. For each patient, we measured event rates for three different 90-day mortality outcomes: all-location mortality, ARDSnet mortality, and in-hospital mortality. We also calculated sample sizes necessary to power an example RCT given those event rates. RESULTS: At 90 days, all-location mortality was 26.4% (95% CI 25.9-26.9%), ARDSnet mortality was 19.2% (95% CI 18.8-19.7%), and in-hospital mortality was 13.4% (95% CI 13.0-13.8%) (p < 0.01 all comparisons). These respective event rates result in different required sample sizes to achieve a 20% relative reduction in mortality with 80% power and a 5% false positive rate. Such a trial of VA sepsis patients would require 2080 patients for all-location mortality, 3080 for ARDSnet mortality, and 4796 for in hospital mortality. Among sepsis patients mechanically ventilated in an ICU, 2438 experienced all-location mortality (46.2% [95% CI 44.8-47.5%]), 2181 experienced ARDSnet mortality (41.3% [95% CI 40.0-42.6%]), and 1894 experienced in-hospital mortality (36.0% [95% CI 34.7-37.3%]). CONCLUSIONS: Event rates vary substantially in sepsis patients based on the chosen 90-day mortality definition. This could have important implications for RCT design trade-offs. PMID- 29587804 TI - Developing measures to assess constructs from the Inner Setting domain of the Consolidated Framework for Implementation Research. AB - BACKGROUND: Scientists and practitioners alike need reliable, valid measures of contextual factors that influence implementation. Yet, few existing measures demonstrate reliability or validity. To meet this need, we developed and assessed the psychometric properties of measures of several constructs within the Inner Setting domain of the Consolidated Framework for Implementation Research (CFIR). METHODS: We searched the literature for existing measures for the 7 Inner Setting domain constructs (Culture Overall, Culture Stress, Culture Effort, Implementation Climate, Learning Climate, Leadership Engagement, and Available Resources). We adapted items for the healthcare context, pilot-tested the adapted measures in 4 Federally Qualified Health Centers (FQHCs), and implemented the revised measures in 78 FQHCs in the 7 states (N = 327 respondents) with a focus on colorectal cancer (CRC) screening practices. To psychometrically assess our measures, we conducted confirmatory factor analysis models (CFA; structural validity), assessed inter-item consistency (reliability), computed scale correlations (discriminant validity), and calculated inter-rater reliability and agreement (organization-level construct reliability and validity). RESULTS: CFAs for most constructs exhibited good model fit (CFI > 0.90, TLI > 0.90, SRMR < 0.08, RMSEA < 0.08), with almost all factor loadings exceeding 0.40. Scale reliabilities ranged from good (0.7 <= alpha < 0.9) to excellent (alpha >= 0.9). Scale correlations fell below 0.90, indicating discriminant validity. Inter-rater reliability and agreement were sufficiently high to justify measuring constructs at the clinic-level. CONCLUSIONS: Our findings provide psychometric evidence in support of the CFIR Inner Setting measures. Our findings also suggest the Inner Setting measures from individuals can be aggregated to represent the clinic level. Measurement of the Inner Setting constructs can be useful in better understanding and predicting implementation in FQHCs and can be used to identify targets of strategies to accelerate and enhance implementation efforts in FQHCs. PMID- 29587805 TI - Patient-centered recruitment and retention for a randomized controlled study. AB - BACKGROUND: Recruitment and retention strategies for patient-centered outcomes research are evolving and research on the subject is limited. In this work, we present a conceptual model of patient-centered recruitment and retention, and describe the recruitment and retention activities and related challenges in a patient-centered comparative effectiveness trial. METHODS: This is a multicenter, longitudinal randomized controlled trial in localized prostate cancer patients. RESULTS: We recruited 743 participants from three sites over 15 months period (January 2014 to March 2015), and followed them for 24 months. At site 1, of the 773 eligible participants, 551 (72%) were enrolled. At site 2, 34 participants were eligible and 23 (68%) enrolled. Of the 434 eligible participants at site 3, 169 (39%) enrolled. We observed that strategies related to the concepts of trust (e.g., physician involvement, ensuring protection of information), communication (e.g., brochures and pamphlets in physicians' offices, continued contact during regular clinic visits and calling/emailing assessment), attitude (e.g., emphasizing the altruistic value of research, positive attitude of providers and research staff), and expectations (e.g., full disclosure of study requirements and time commitment, update letters) facilitated successful patient recruitment and retention. A stakeholders' advisory board provided important input for the recruitment and retention activities. Active engagement, reminders at the offices, and personalized update letters helped retention during follow-up. Usefulness of telephone recruitment was site specific and, at one site, the time requirement for telephone recruitment was a challenge. CONCLUSIONS: We have presented multilevel strategies for successful recruitment and retention in a clinical trial using a patient-centered approach. Our strategies were flexible to accommodate site-level requirements. These strategies as well as the challenges can aid recruitment and retention efforts of future large-scale, patient-centered research studies.

PMID- 29587806 TI - A comparison study on the behavior of human endometrial stem cell-derived osteoblast cells on PLGA/HA nanocomposite scaffolds fabricated by electrospinning and freeze-drying methods. AB - BACKGROUND: An engineered tissue structure is an artificial scaffold combined with cells and signaling factors. Among various polymers, the polylactide-co glycolide/hydroxyapatite (PLGA/HA) has attracted much attention due to their optimal properties. The aim of this study was to study the behavior of human endometrial stem cell (hEnSC)-derived osteoblast cells cultured on PLGA/HA nanocomposite scaffolds. METHODS: hEnSCs were isolated and exposed to osteogenic media for 21 days. Differentiated cells were cultured on PLGA/HA synthetic scaffolds. The PLGA/HA-based nanocomposite scaffolds were fabricated using either electrospinning or freeze-drying methods. Behavior of the cells was evaluated a week after seeding hEnSC-derived osteoblast-like cells on these scaffolds. Osteogenesis was investigated in terms of alkaline phosphatase activity, gene expression, immunocytochemistry (ICC), proliferation, and scanning electron microscopy (SEM). Moreover, scaffold properties, such as pore size and morphology of the cells, onto the scaffolds were evaluated using SEM. Furthermore, biocompatibility of these scaffolds was confirmed by 3-(4,5-dimethylthiazoyl-2 yl)-2,5-diphenyltetrazolium bromide (MTT) assay. RESULTS: The matrix mineralization was proved by alizarin red staining, and the osteogenic media treated cultures positively expressed osteocalcin and osteopontin markers. Moreover, qRT-PCR results confirmed the positive gene expression of osteopontin and osteonectin in the differentiated osteoblast-like cells. The results of behavior assessment of the cultured cells on electrospinning and freeze-dried scaffolds showed that the behavior of the cultured cells on the freeze-dried PLGA/HA scaffolds was significantly better than the electrospinning PLGA/HA scaffolds. CONCLUSION: It has been shown that the freeze-dried PLGA/HA nanocomposite scaffolds can appropriately support the attachment and proliferation of the differentiated osteoblast cells and are a suitable candidate for bone tissue engineering. PMID- 29587807 TI - Acceptance and Commitment Therapy preceded by an experimental Attention Bias Modification procedure in recurrent depression: study protocol for a randomized controlled trial. AB - BACKGROUND: This project studies the effect of group-based Acceptance and Commitment Therapy (ACT) following Attention Bias Modification (ABM) on residual symptoms in recurrent depression. ACT is a cognitive-behavioral intervention combining acceptance and mindfulness processes with commitment and behavior change processes. ACT enjoys modest empirical support in treating depression and has also shown promising results in secondary prevention of depression. The experimental cognitive bias modification (ABM) procedure has been shown to reduce surrogate markers of depression vulnerability in patients in remission from depression. The aim of the current project is to investigate if the effect of group-based ACT on reducing residual depressive symptoms can be enhanced by preceding it with ABM. Also, assessment of the relationship between conceptually relevant therapeutic processes and outcome will be investigated. METHODS/DESIGN: An invitation to participate in this project was extended to 120 individuals within a larger sample who had just completed a separate randomized, multisite, clinical trial (referred to hereafter as Phase 1) in which they received either ABM (n = 60) or a control condition without bias modification (n = 60). This larger Phase-1 sample consisted of 220 persons with a history of at least two episodes of major depression who were currently in remission or not fulfilling the criteria of major depression. After its inclusion, Phase-1 participants from the Sorlandet site (n = 120) were also recruited for this study in which they received an 8-week group-based ACT intervention. Measures will be taken immediately after Phase 1, 1 month, 2 months, 6 months, and 1 year after the conclusion of Phase 1. DISCUSSION: This study sequentially combines acceptable, nondrug interventions from neuropsychology and cognitive-behavioral psychology in treating residual symptoms in depression. The results will provide information about the effectiveness of treatment and on mechanisms and processes of change that may be valuable in understanding and further developing ABM and ACT, combined and alone.

PMID- 29587808 TI - The ideal time of systemic metronidazole and amoxicillin administration in the treatment of severe periodontitis: study protocol for a randomized controlled trial. AB - BACKGROUND: The combination of systemic metronidazole (MTZ) and amoxicillin (AMX) with scaling and root planing (SRP) has shown to be an effective periodontal treatment. However, some essential issues associated with the use of these antibiotics remain unanswered, such as the ideal time of administration during the course of periodontal treatment. Although these agents are often prescribed after the healing phase of the SRP procedure, there is biological plausibility to support its use in conjunction with the mechanical treatment. However, to date, no placebo controlled randomized clinical trial (RCT) has directly compared these two protocols. Therefore, the aim of this RCT is to compare the clinical, microbiological and immunological effects of the adjunctive systemic MTZ + AMX administered in different phases of the treatment of severe periodontitis. METHODS: Subjects with severe periodontitis (n = 180) are being randomly assigned into three groups (n = 60/group): (i) SRP-only (control group), SRP in combination with 400 mg MTZ + 500 mg AMX, starting (ii) at the first SRP session (active phase group), or (iii) after 3 months of its completion (healing phase group). All volunteers are receiving clinical and microbiological evaluation at baseline, 3, 6 and 12 months, and immunological assessment at baseline and 12 months post-therapy. Nine subgingival biofilm samples are being collected per subject and analyzed for counts and proportions of 40 bacterial species by checkerboard DNA-DNA hybridization, and six gingival crevicular fluid samples are being collected and analyzed for the levels of 20 chemokines by multiplex immunoassay. The primary outcome variable is the number of volunteers reaching the clinical endpoint for treatment (<= 4 sites with probing depth >=5 mm) at 1 year post-therapy. Differences in clinical, microbiological and immunological parameters among groups and over time will be evaluated using analysis of variance, analysis of covariance and the Chi-square and Tukey tests. Microbiological and immunological analyses will be performed using adjustments for multiple comparisons. Statistical significance will be set at 5%.

PMID- 29587809 TI - Assessing the outcomes of everolimus on renal angiomyolipoma associated with tuberous sclerosis complex in China: a two years trial. AB - BACKGROUND: Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disorder characterized by the development of numerous benign tumors. Renal angiomyolipoma (RAML) occur in up to 80% of TSC patients, which is a leading cause of TSC-related death in adult patients. The aim of the study was to evaluate the efficacy and safety profiles of everolimus in Chinese patients of TSC associated with RAML(TSC-RAML). METHODS: In this 2-years, nonrandomized, open label trial, 18 patients of TSC-RAML, with at least one RAML 3 cm or larger in its longest diameter, were enrolled to assess the efficacy and safety of everolimus therapy in Chinese patients. Everolimus was administered for the first 12 months only. The primary endpoint was a reduction of 50% or more relative in RAML volume to the baseline in the absence of new RAML >=1 cm and no RAML-related bleeding of grade >= 2. The secondary endpoints included: safety, lung function and skin lesions response rate. Serial computed tomography of RAML, magnetic resonance imaging of brain lesions and pulmonary-function tests were performed. Adverse events were investigated using CTCAE v4.0. All analyses used a significance level of 0.05 and were generated in SPSS19.0 software. RESULTS: The proportion of patients who achieved >=50% reduction from baseline in the sum of volumes of target lesions increased from 52.94% at 3 months, to 58.82% and 66.67% at months 6 and 12, respectively. During the period of everolimus therapy, among patients with lymphangioleiomyomatosis, the mean forced expiratory volume in 1 s (FEV1) increased by 276 +/- 78 ml (P < 0.001), the forced vital capacity (FVC) increased by 433 +/- 170 ml (P < 0.001), and the residual volume decreased by 408 +/- 243 ml (P = 0.009), as compared with baseline values. The angiomyolipoma volume and the lung function approached, but did not completely return to, the baseline values. The skin lesions response rate was 37.5% after 12 months of therapy falling to 21.4% at 12 months after stopping everolimus. The most common adverse events were mucositis oral, irregular menstruation, abdominal pain, hypertriglyceridemia and headache. The most common grade 3 adverse events were irregular menstruation and mucositis oral. In addition, one patient died from RAML spontaneous haemorrhage during treatment with everolimus, even with reduction in RAML volume of 60.68% at 3 months. A second death was due to epithelioid RAML progression, with metastasis to multiple retroperitoneal lymph node, who died from severe infection one month after surgery. CONCLUSIONS: Angiomyolipomas regressed somewhat during everolimus therapy but tended to increase in volume after the therapy was stopped. Everolimus was well tolerated and showed promising activity in Chinese patients with TSC-RAML, however, we should alert the life-threatening hemorrhage of large RAML in the early period and the lymph node metastasis of epithelioid RAML.

AB - Survival from out-of-hospital cardiac arrest (OHCA) has remained low despite advances in resuscitation science. Hospital-based extra-corporeal cardiopulmonary resuscitation (ECPR) is a novel use of an established technology that provides greater blood flow and oxygen delivery during cardiac arrest than closed chest compressions. Hospital-based ECPR is currently offered to selected OHCA patients in specialized centres. The interval between collapse and restoration of circulation is inversely associated with good clinical outcomes after ECPR. Pre hospital delivery of ECPR concurrent with conventional resuscitation is one approach to shortening this interval and improving outcomes after OHCA. This article examines the background and rationale for pre-hospital ECPR; summarises the findings of a literature search for published evidence; and considers candidate selection, logistics, and complications for this complex intervention. PMID- 29587812 TI - Validation of the Neonatal Satisfaction Survey (NSS-8) in six Norwegian neonatal intensive care units: a quantitative cross-sectional study. AB - BACKGROUND: The experience of having their new-borns admitted to an intensive care unit (NICU) can be extremely distressing. Subsequent risk of post-incident adjustment difficulties are increased for parents, siblings, and affected families. Patient and next of kin satisfaction surveys provide key indicators of quality in health care. Methodically constructed and validated survey tools are in short supply and parents' experiences of care in Neonatal Intensive Care Units is under-researched. This paper reports a validation of the Neonatal Satisfaction Survey (NSS-8) in six Norwegian NICUs. METHODS: Parents' survey returns were collected using the Neonatal Satisfaction Survey (NSS-13). Data quality and psychometric properties were systematically assessed using exploratory factor analysis, tests of internal consistency, reliability, construct, convergent and discriminant validity. Each set of hospital returns were subjected to an apostasy analysis before an overall satisfaction rate was calculated. RESULTS: The survey sample of 568 parents represents 45% of total eligible population for the period of the study. Missing data accounted for 1,1% of all returns. Attrition analysis shows congruence between sample and total population. Exploratory factor analysis identified eight factors of concern to parents,"Care and Treatment", "Doctors", "Visits", "Information", "Facilities", "Parents' Anxiety", "Discharge" and "Sibling Visits". All factors showed satisfactory internal consistency, good reliability (Cronbach's alpha ranged from 0.70-0.94). For the whole scale of 51 items alpha 0.95. Convergent validity using Spearman's rank between the eight factors and question measuring overall satisfaction was significant on all factors. Discriminant validity was established for all factors. Overall satisfaction rates ranged from 86 to 90% while for each of the eight factors measures of satisfaction varied between 64 and 86%. CONCLUSION: The NSS-8 questionnaire is a valid and reliable scale for measuring parents' assessment of quality of care in NICU. Statistical analysis confirms the instrument's capacity to gauge parents' experiences of NICU. Further research is indicated to validate the survey questionnaire in other Nordic countries and beyond. PMID- 29587813 TI - Use patterns, use values and management of Afzelia africana Sm. in Burkina Faso: implications for species domestication and sustainable conservation. AB - BACKGROUND: The lack of literature on the interactions between indigenous people and the valuable agroforestry trees hinder the promotion of sustainable management of plant resources in West African Sahel. This study aimed at assessing local uses and management of Afzelia africana Sm. in Burkina Faso, as a prerequisite to address issues of domestication and sustainable conservation. METHODS: One thousand forty-four peoples of seven dominant ethnic groups were questioned in 11 villages through 221 semi-structured focus group interviews. The surveys encompassed several rural communities living around six protected areas along the species distribution range. Questions refer mainly to vernacular names of A. africana, locals' motivations to conserve the species, the uses, management practices and local ecological knowledge on the species. Citation frequency was calculated for each response item of each questionnaire section to obtain quantitative data. The quantitative data were then submitted to comparison tests and multivariate statistics in R program. RESULTS: A. africana is a locally well known tree described as a refuge of invisible spirits. Due to this mystery and its multipurpose uses, A. africana is conserved within the agroforestry systems. The species is widely and mostly used as fodder (87.55%), drugs (75.93%), fetish or sanctuary (70.95%), food (41.49%), and raw material for carpentry (36.19%) and construction (7.05%). While the uses as fodder, food and construction involved one organ, the leaves and wood respectively, the medicinal use was the most diversified. All tree organs were traditionally used in 10 medical prescriptions to cure about 20 diseases. The species use values differed between ethnic groups with lower values within the Dagara and Fulani. The findings reveal a total absence of specific management practices such as assisted natural regeneration, seeding, or transplantation of A. africana sapling. However, trees were permanently pruned and debarked by local people. Harvesting of barks mostly contributed to the decline of the species populations. Local people acknowledged declining populations of A. africana with lower densities within the agroecosystems. They also perceived between individuals, variations in the traits of barks, leaves, fruits and seeds. Significant differences were found between ethnic groups and gender regarding the species uses. Local knowledge on the species distribution differed between ethnic groups. CONCLUSION: This study showed the multipurpose uses of A. africana throughout Burkina Faso. The results provide relevant social and ecological indicators to all stakeholders and constitute a springboard towards the species domestication and the elaboration of efficient sustainable conservation plans. PMID- 29587811 TI - Angiostrongylus vasorum and Aelurostrongylus abstrusus: Neglected and underestimated parasites in South America. AB - The gastropod-borne nematodes Angiostrongylus vasorum and Aelurostrongylus abstrusus are global causes of cardio/pulmonary diseases in dogs and cats. In the last decade, the number of reports on canine and feline lungworms has increased in several areas of Europe and North America. The unspecific clinical signs and prolonged course of these diseases often renders diagnosis challenging. Both infections are considered as emerging and underestimated causes of disease in domestic pets. In South America, little information is available on these diseases, apart from occasional reports proving the principle presence of A. vasorum and A. abstrusus. Thus, the purpose of this review is to summarize reports on infections in both domestic and wildlife animals in South America and to increase the awareness on gastropod-borne metastrongyloid parasites, which also include important zoonotic species, such as A. cantonensis and A. costaricensis. This review highlights the usefulness of diagnostic tools, such as the Baermann funnel technique, serology and PCR, and proposes to include these routinely on cases with clinical suspicion for lungworm infections. Future national epidemiological surveys are recommended to be conducted to gain a deeper insight into the actual epidemiological situation of gastropod-borne parasitoses in South America. PMID- 29587814 TI - A comparative analysis of pharmacists' perspectives on codeine use and misuse - a three country survey. AB - BACKGROUND: The misuse of codeine is of increasing concern in a number of countries, particularly as this relates to over -the-counter pain and cough relief medication, and is also supplied as a prescription medicine. The study aimed to obtain and analyse the opinions and experience of pharmacy staff with regard to codeine misuse. METHODS: A cross-sectional web-based survey of pharmacy staff's perspectives on this issue was administered through professional or regulatory bodies and completed by samples drawn in South Africa (n = 124), Ireland (n = 464) and the United Kingdom (n = 129). RESULTS: The majority of participants reported combination codeine-containing products as most popular, but significantly more pharmacy staff in South Africa reported codeine-containing cough syrups as most commonly popular (X2 = 122.7(2), p < 0.001). Codeine use was also seen significantly more of a public health problem in South Africa than in the other two countries (X2 = 7.6(2), p = 0.02). There was no difference across countries in the level of codeine misuse reported by pharmacy staff. Further findings indicate that professional training and education is desired, with unequivocal findings for the need for greater codeine control (X2 = 12.0(2), p = 0.002). CONCLUSION: In conclusion, there were some inter-country differences, but overall the findings seem to suggest that pharmacists across all three countries view codeine misuse as a problem among their customers.

AB - BACKGROUND: Pleural effusion is a rare complication of ventriculo-peritoneal (VP) cerebrospinal fluid (CSF) shunting and its diagnosis is difficult in patients with neurological and consciousness impairment. CASE REPORT: Herein we report the case of a child affected by Pfeiffer syndrome and hydrocephalus, shunted at the age of 3 months, who developed acute respiratory failure due to a right-sided pleural effusion 2 years later. Plain chest radiographs and computed tomography (CT) showed the intrathoracic migration of the right VP shunt abdominal tip. Beta 2 transferrin, a marker for CSF, was found in the pleural fluid and the hypothesis of a CSF hydrothorax was confirmed. Effusion was treated with a thoracentesis. Seven days after, the right VP shunt was revised; a ventriculo atrial (VA) shunt was also placed on the left side to serve as the main CSF shunt and to prevent the recurrence of hydrothorax. We review the pediatric cases of CSF hydrothorax reported in the literature and discuss the mechanisms underlying this complication together with the possible treatments. CONCLUSION: Pleural effusion due to VP shunt insertion is a rare and potentially life-threatening condition that should be suspected in any patient with a VP shunt and respiratory failure. Signs of hydrothorax may moreover represent the only clinical evidence of a shunt-related complication in case of neurologically severely compromised patients in which neurologic examination cannot help to make a diagnosis. PMID- 29587816 TI - Indicators of intensive care unit capacity strain: a systematic review. AB - BACKGROUND: Strained intensive care unit (ICU) capacity represents a fundamental supply-demand mismatch in ICU resources. Strain is likely to be influenced by a range of factors; however, there has been no systematic evaluation of the spectrum of measures that may indicate strain on ICU capacity. METHODS: We performed a systematic review to identify indicators of strained capacity. A comprehensive peer-reviewed search of MEDLINE, EMBASE, CINAHL, Cochrane Library, and Web of Science Core Collection was performed along with selected grey literature sources. We included studies published in English after 1990. We included studies that: (1) focused on ICU settings; (2) included description of a quality or performance measure; and (3) described strained capacity. Retrieved studies were screened, selected and extracted in duplicate. Quality was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). Analysis was descriptive. RESULTS: Of 5297 studies identified in our search; 51 fulfilled eligibility. Most were cohort studies (n = 39; 76.5%), five (9.8%) were case control, three (5.8%) were cross-sectional, two (3.9%) were modeling studies, one (2%) was a correlational study, and one (2%) was a quality improvement project. Most observational studies were high quality. Sixteen measures designed to indicate strain were identified 110 times, and classified as structure (n = 4, 25%), process (n = 7, 44%) and outcome (n = 5, 31%) indicators, respectively. The most commonly identified indicators of strain were ICU acuity (n = 21; 19.1% [process]), ICU readmission (n = 18; 16.4% [outcome]), after-hours discharge (n = 15; 13.6% [process]) and ICU census (n = 13; 11.8% [structure]). There was substantial heterogeneity in the operational definitions used to define strain indicators across studies. CONCLUSIONS: We identified and characterized 16 indicators of strained ICU capacity across the spectrum of healthcare quality domains. Future work should aim to evaluate their implementation into practice and assess their value for evaluating strategies to mitigate strain.

PMID- 29587817 TI - The effect of chlorhexidine on dental calculus formation: an in vitro study. AB - BACKGROUND: Chlorhexidine gluconate (CHG) has been proven to be effective in preventing and controlling biofilm formation. At the same time, an increase in calculus formation is known as one of considerable side effects. The purpose of this study was to investigate whether mineral deposition preceding a calculus formation would occur at an early stage after the use of CHG using an in vitro saliva-related biofilm model. METHODS: Biofilms were developed on the MBECTM device in brain heart infusion (BHI) broth containing 0.5% sucrose at 37 degrees C for 3 days under anaerobic conditions. Biofilms were periodically exposed to 1 min applications of 0.12% CHG every 12 h and incubated for up to 2 days in BHI containing a calcifying solution. Calcium and phosphate in the biofilm were measured using atomic absorption spectrophotometry and a phosphate assay kit, respectively. Morphological structure was observed using a scanning electron microscope (SEM), and chemical composition was analyzed with an electron probe microanalyzer (EPMA). RESULTS: The concentrations of Ca and Pi following a single exposure to CHG increased significantly compared with the control. Repeatedly exposing biofilms to CHG dose-dependently increased Ca deposition, and the amount of Ca was five times as much as that of the control. Pi levels in CHG-treated biofilms were significantly higher than those from the control group (p < 0.05); however, the influence of the number of exposures was limited. Analyses using an SEM and EPMA showed many clusters containing calcium and phosphate complexes in CHG-treated biofilms. Upon composition analysis of the clusters, calcium was detected at a greater concentration than phosphate. CONCLUSIONS: Findings suggested that CHG may promote mineral uptake into the biofilm soon after its use. It is necessary to disrupt the biofilm prior to the start of a CHG mouthwash in order to reduce the side effects associated with this procedure. The management of patients is also important. PMID- 29587818 TI - 5'/ 3' imbalance strategy to detect ALK fusion genes in circulating tumor RNA from patients with non-small cell lung cancer. AB - BACKGROUND: Detecting an ALK fusion gene in patients with non-small cell lung cancer (NSCLC) could provide evidence to guide individualized therapy. METHODS: The 5'/3' imbalance strategy for quantitative reverse transcription-PCR (RT-qPCR) was developed to detect ALK fusion genes in circulating tumor RNA (ctRNA) of NSCLC patients. RESULTS: This method was validated in patients with the ALK fusion gene confirmed by next generation sequencing (NGS). The amount of the ALK fusion gene detected by the new method ranged from 33.2 to 987.4, (mean 315.2), in the patients confirmed to have the ALK fusion gene (+). This is much higher than the amount of fusion gene detected in the patients who are negative for the ALK fusion gene (-). The amount detected in the ALK fusion gene (-) samples ranged from 0.36 to 13.04, (mean 4.58). In 188 NSCLC patients, the specificity and sensitivity of the method was compared to that of the FISH method. About 10.64% of the patients showed higher ALK fusion gene expression, and were classified as ALK fusion gene (+). This is identical to the percentage of patients detected by the FISH method to be ALK fusion gene (+). The cutoff value for diagnosis of ALK fusion (+) is 32.9 as determined by this method. CONCLUSIONS: A new RT-PCR method using a 5'/3' imbalance strategy was developed, with high specificity and sensitivity, for detection of the ALK fusion gene in ctRNA of NSCLC patients. This method can rapidly detect ALK fusion genes in patients, which will be helpful for guiding targeted therapy, particularly the individualized usage of TKIs in these patients. PMID- 29587819 TI - Diverse laboratory colonies of Aedes aegypti harbor the same adult midgut bacterial microbiome. AB - BACKGROUND: Host-associated microbes, collectively known as the microbiota, play an important role in the biology of multicellular organisms. In mosquito vectors of human pathogens, the gut bacterial microbiota influences vectorial capacity and has become the subject of intense study. In laboratory studies of vector biology, genetic effects are often inferred from differences between geographically and genetically diverse colonies of mosquitoes that are reared in the same insectary. It is unclear, however, to what extent genetic effects can be confounded by uncontrolled differences in the microbiota composition among mosquito colonies. To address this question, we used 16S metagenomics to compare the midgut bacterial microbiome of six laboratory colonies of Aedes aegypti recently derived from wild populations representing the geographical range and genetic diversity of the species. RESULTS: We found that the diversity, abundance, and community structure of the midgut bacterial microbiome was remarkably similar among the six different colonies of Ae. aegypti, regardless of their geographical origin. We also confirmed the relatively low complexity of bacterial communities inhabiting the mosquito midgut. CONCLUSIONS: Our finding that geographically diverse colonies of Ae. aegypti reared in the same insectary harbor a similar gut bacterial microbiome supports the conclusion that the gut microbiota of adult mosquitoes is environmentally determined regardless of the host genotype. Thus, uncontrolled differences in microbiota composition are unlikely to represent a significant confounding factor in genetic studies of vector biology.

PMID- 29587821 TI - Study on the species composition and ecology of anophelines in Addis Zemen, South Gondar, Ethiopia. AB - BACKGROUND: Malaria is a public health problem in Ethiopia and its transmission is generally unstable and seasonal. For the selection of the most appropriate vector control measures, knowledge on the ecology of the vector is necessary at a local level. Therefore, the objectives of this study were to document the species composition, breeding habitat characteristics and occurrence of anopheline larva in Sheni stream and the vectorial role of the prevailing Anopheles in relation to malaria transmission in Addis Zemen, Ethiopia. METHODS: Immature anophelines were sampled from breeding habitats and characteristics, such as water temperature, turbidity, water current, water pH and other variables, of the habitats were measured from October 2011 to February 2012. Adult anophelines were sampled inside human dwellings using space spray and Center for Disease Control light traps. Artificial pit shelters and clay pots were also used for outdoor adult collections. Anophelines collected were identified using morphological key. The enzyme-linked immunosorbent assay was applied to detect circumsporozoite proteins of Plasmodium and source of blood meals. RESULTS: A total of 6258 Anopheles larvae were collected and identified morphologically. Five anopheline species were found: An. gambiae (s.l.), An. cinereus, An. demeilloni, An. christi and An. pretoriensis. Anopheles gambiae (s.l.) existed in most of the habitats investigated. Only the former three species were captured in the adult collections. Sun-lit Sheni stream, rain pools, hoof prints, drainage and irrigation canals were found to be habitats of larvae. Anopheles gambiae (s.l.) larvae were most abundantly sampled from sand mining and natural sand pools of Sheni stream. Multiple regression analysis showed that clear, permanent and temporary habitats devoid of mats of algae were the best predictors of An. gambiae (s.l.) larval abundance. It is also the responsible malaria vector in the study area and exhibits anthropophilic and endophagic behaviour. CONCLUSIONS: The malaria vector An. gambiae (s.l.) was found in Addis Zemen throughout the study period from both adult and larval collections. Sheni stream is the main larval habitat responsible for the occurrence of anopheline larvae during the dry season of the study area when other breeding sites perish. PMID- 29587822 TI - Degenerate codon mixing for PCR-based manipulation of highly repetitive sequences. AB - OBJECTIVE: Repeat expansion of polyglutamine tracks leads to a group of inherited human neurodegenerative disorders. Studying such repetitive sequences is required to gain insight into the pathophysiology of these diseases. PCR-based manipulation of repetitive sequences, however, is challenging due to the absence of unique primer binding sites or the generation of non-specific products. RESULTS: We have utilised the degeneracy of the genetic code to generate a polyglutamine sequence with low repeat similarity. This strategy allowed us to use conventional PCR to generate multiple constructs with approximately defined numbers of glutamine repeats. We then used these constructs to measure the in vivo variation in autophagic degradation activity related to the different numbers of glutamine repeats, providing an example of their applicability to study repeat expansion diseases. Our simple and easily generalised method of generating low repetition DNA sequences coding for uniform stretches of amino acid residues provides a strategy for generating particular lengths of polyglutamine tracts using standard PCR and cloning protocols. PMID- 29587823 TI - Multiple functions of m6A RNA methylation in cancer. AB - First identified in 1974, m6A RNA methylation, which serves as a predominant internal modification of RNA in higher eukaryotes, has gained prodigious interest in recent years. Modifications of m6A are dynamic and reversible in mammalian cells, which have been proposed as another layer of epigenetic regulation similar to DNA and histone modifications. m6A RNA methylation is involved in all stages in the life cycle of RNA, ranging from RNA processing, through nuclear export, translation modulation to RNA degradation, which suggests its potential of influencing a plurality of aspects of RNA metabolism. All of the recent studies have pointed to a complicated regulation network of m6A modification in different tissues, cell lines, and space-time models. m6A methylation has been found to have an impact on tumor initiation and progression through various mechanisms. Furthermore, m6A RNA methylation has provided new opportunities for early stage diagnosis and treatment of cancers.Herein, we review the chemical basis of m6A RNA methylation, its multiple functions and potential significance in cancer. PMID- 29587824 TI - Distinctive epigenomes characterize glioma stem cells and their response to differentiation cues. AB - BACKGROUND: Glioma stem cells (GSCs) are a subpopulation of stem-like cells that contribute to glioblastoma (GBM) aggressiveness, recurrence, and resistance to radiation and chemotherapy. Therapeutically targeting the GSC population may improve patient survival, but unique vulnerabilities need to be identified. RESULTS: We isolate GSCs from well-characterized GBM patient-derived xenografts (PDX), characterize their stemness properties using immunofluorescence staining, profile their epigenome including 5mC, 5hmC, 5fC/5caC, and two enhancer marks, and define their transcriptome. Fetal brain-derived neural stem/progenitor cells are used as a comparison to define potential unique and common molecular features between these different brain-derived cells with stem properties. Our integrative study reveals that abnormal expression of ten-eleven-translocation (TET) family members correlates with global levels of 5mC and 5fC/5caC and may be responsible for the distinct levels of these marks between glioma and neural stem cells. Heterogenous transcriptome and epigenome signatures among GSCs converge on several genes and pathways, including DNA damage response and cell proliferation, which are highly correlated with TET expression. Distinct enhancer landscapes are also strongly associated with differential gene regulation between glioma and neural stem cells; they exhibit unique co-localization patterns with DNA epigenetic mark switching events. Upon differentiation, glioma and neural stem cells exhibit distinct responses with regard to TET expression and DNA mark changes in the genome and GSCs fail to properly remodel their epigenome. CONCLUSIONS: Our integrative epigenomic and transcriptomic characterization reveals fundamentally distinct yet potentially targetable biologic features of GSCs that result from their distinct epigenomic landscapes. PMID- 29587825 TI - Inflammatory interferon activates HIF-1alpha-mediated epithelial-to-mesenchymal transition via PI3K/AKT/mTOR pathway. AB - BACKGROUND: Tumor microenvironments (TMEs) activate various axes/pathways, predominantly inflammatory and hypoxic responses, impact tumorigenesis, metastasis and therapeutic resistance significantly. Although molecular pathways of individual TME are extensively studied, evidence showing interaction and crosstalk between hypoxia and inflammation remain unclear. Thus, we examined whether interferon (IFN) could modulate both inflammatory and hypoxic responses under normoxia and its relation with cancer development. METHODS: IFN was used to induce inflammation response and HIF-1alpha expression in various cancer cell lines. Corresponding signaling pathways were then analyzed by a combination of pharmacological inhibitors, immunoblotting, GST-Raf pull-down assays, dominant negative and short-hairpin RNA-mediated knockdown approaches. Specifically, roles of functional HIF-1alpha in the IFN-induced epithelial-mesenchymal transition (EMT) and other tumorigenic propensities were examined by knockdown, pharmacological inhibition, luciferase reporter, clonogenic, anchorage independent growth, wound-healing, vasculogenic mimicry, invasion and sphere formation assays as well as cellular morphology observation. RESULTS: We showed for the first time that IFN induced functional HIF-1alpha expression in a time- and dose- dependent manner in various cancer cell lines under both hypoxic and normoxic conditions, and then leading to an activated HIF-1alpha pathway in an IFN-mediated pro-inflammatory TME. IFN regulates anti-apoptosis activity, cellular metastasis, EMT and vasculogenic mimicry by a novel mechanism through mainly the activation of PI3K/AKT/mTOR axis. Subsequently, pharmacological and genetic modulations of HIF-1alpha, JAK, PI3K/AKT/mTOR or p38 pathways efficiently abrogate above IFN-induced tumorigenic propensities. Moreover, HIF-1alpha is required for the IFN-induced invasiveness, tumorigenesis and vasculogenic mimicry. Further supports for the HIF-1alpha-dependent tumorigenesis were obtained from results of xenograft mouse model and sphere-formation assay. CONCLUSIONS: Our mechanistic study showed an induction of HIF-1alpha and EMT ability in an IFN-mediated inflammatory TME and thus demonstrating a novel interaction between inflammatory and hypoxic TMEs. Moreover, targeting HIF-1alpha may be a potential target for inhibiting tumor tumorigenesis and EMT by decreasing cancer cells wound healing and anchorage-independent colony growth. Our results also lead to rationale guidance for developing new therapeutic strategies to prevent relapse via targeting TME-providing IFN signaling and HIF 1alpha programming. PMID- 29587826 TI - Life course factors associated with metabolically healthy obesity: a protocol for the systematic review of longitudinal studies. AB - BACKGROUND: There is heterogeneity among obese individuals, as some appear to have healthier metabolic profiles and decreased health risks. These individuals are defined as metabolically healthy obese (MHO), whilst those with unhealthy metabolic profiles are defined as metabolically unhealthy obese (MUO). To date, most research on MHO has been cross-sectional or focused on disease prognosis. However, longitudinal studies are required to provide greater insight into the life course factors that contribute to the development of MHO. This study aims to systematically review longitudinal studies investigating the association between life course exposures and future MHO status. METHODS: Electronic databases (MEDLINE, SCOPUS, and Web of Science) will be searched using a trialled search strategy. Studies will be included following a double-screening process according to inclusion criteria to assess eligibility. Studies eligible for inclusion will include those that have a longitudinal observational design where a life course exposure occurred or was measured at least 1 year before the outcome, investigate a human study population, are published in English after 1956, and investigate the association between >= 1 life course exposure and >= 1 outcome that reflects a measure of cardiometabolic resilience to obesity. Accepted life course exposures will include body size, body composition, pubertal development, smoking, diet, physical activity, sedentary behaviour, and psychosocial stress. The primary measure of cardiometabolic resilience to obesity will be MHO as an outcome (at follow-up). Studies investigating the development of cardiometabolic risk factors in an obese group without specifying MHO will also be accepted, such as the development of the metabolic syndrome (MetS) in an obese group. Key results of included studies will be tabulated, and a narrative synthesis will be conducted. DISCUSSION: This will be the first systematic review to summarise the literature on the life course correlates of MHO. Importantly, it may highlight which modifiable lifestyle factors could be targeted to delay the onset of cardiometabolic complications among the obese.

PMID- 29587827 TI - Use of a meta-analysis to assess the preventive effect of dexmedetomidine on cardiac surgery-associated acute kidney injury. PMID- 29587828 TI - The need to revisit the definition of mesenchymal and adult stem cells based on their functional attributes. AB - A debate is ongoing about the 'stem cell' status of mesenchymal stem cells (MSCs). This can easily be resolved based on the definition of a stem cell. 'True' stem cells are expected to undergo asymmetric cell divisions (ACD) whereby they divide to self-renew and give rise to a slightly bigger, differentiated cell. However, MSCs like any other adult tissue-specific stem cells, including hematopoietic (HSCs), spermatogonial (SSCs) and ovarian (OSCs) stem cells, do not undergo ACD; rather they undergo rapid symmetrical cell divisions. The true stem cells in adult tissues are possibly the pluripotent stem cells termed very small embryonic-like stem cells (VSELs), which were recently shown to undergo ACD to give rise to tissue-specific stem cells 'progenitors' (currently termed 'adult stem cells') that in turn undergo rapid symmetric cell divisions and clonal expansion (sphere formation with incomplete cytokinesis) followed by differentiation into tissue-specific cell types. MSCs can be cultured from any tissue source and are an excellent source of growth factors/cytokines and thus could provide a niche for proper functioning of the stem/progenitor cells. PMID- 29587829 TI - How do we define and measure sarcopenia? Protocol for a systematic review. AB - BACKGROUND: The loss of muscle mass is a natural aging consequence. A reduction of muscle mass that surpasses the physiological rate is considered the key factor responsible for the development of a geriatric syndrome called sarcopenia. However, a new understanding of the importance of muscle quality over quantity is rising; as a result, different definitions for sarcopenia has been used. Due to the negative impact on elder's health and quality of life, the number of research investigating the causes, prevalence, and management of sarcopenia is increasing, although a consensus on sarcopenia definition is still missing. This systematic review will assess observational studies reporting the presence of sarcopenia aiming to verify how sarcopenia is defined, the diagnosis criteria, and the tools used for assessment. In addition, we will investigate the influence of the definition and diagnostic tools on the prevalence rate. METHODS: Keywords related to the condition, population, and type of study will be combined to build a search strategy for each of the following databases MEDLINE, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Web of Science, and Google Scholar. Two independent reviewers will analyze the retrieved papers for eligibility and the methodological quality of eligible studies. The definition of sarcopenia and diagnostic tools used in each study and the prevalence estimates will be extracted. Descriptive statistics will be used to report the definitions of sarcopenia, diagnostic tools, and whether these influence or not, the prevalence rates. DISCUSSION: Sarcopenia is receiving greater attention in geriatrics research in recent years. Therefore, it is important to investigate how this condition is defined in the literature and whether these definitions can interfere with the reported estimates devoting more efforts on the topic. The results of this study can help to determine the most used definitions of sarcopenia reported in the literature, its strengths and limitations, and open a discussion about a need for a more valid, easy, and suitable one. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015020832. PMID- 29587830 TI - Seasonal and algal diet-driven patterns of the digestive microbiota of the European abalone Haliotis tuberculata, a generalist marine herbivore. AB - BACKGROUND: Holobionts have a digestive microbiota with catabolic abilities allowing the degradation of complex dietary compounds for the host. In terrestrial herbivores, the digestive microbiota is known to degrade complex polysaccharides from land plants while in marine herbivores, the digestive microbiota is poorly characterized. Most of the latter are generalists and consume red, green, and brown macroalgae, three distinct lineages characterized by a specific composition in complex polysaccharides, which represent half of their biomass. Subsequently, each macroalga features a specific epiphytic microbiota, and the digestive microbiota of marine herbivores is expected to vary with a monospecific algal diet. We investigated the effect of four monospecific diets (Palmaria palmata, Ulva lactuca, Saccharina latissima, Laminaria digitata) on the composition and specificity of the digestive microbiota of a generalist marine herbivore, the abalone, farmed in a temperate coastal area over a year. The microbiota from the abalone digestive gland was sampled every 2 months and explored using metabarcoding. RESULTS: Diversity and multivariate analyses showed that patterns of the microbiota were significantly linked to seasonal variations of contextual parameters but not directly to a specific algal diet. Three core genera: Psychrilyobacter, Mycoplasma, and Vibrio constantly dominated the microbiota in the abalone digestive gland. Additionally, a less abundant and diet specific core microbiota featured genera representing aerobic primary degraders of algal polysaccharides. CONCLUSIONS: This study highlights the establishment of a persistent core microbiota in the digestive gland of the abalone since its juvenile state and the presence of a less abundant and diet-specific core community. While composed of different microbial taxa compared to terrestrial herbivores, the digestive gland constitutes a particular niche in the abalone holobiont, where bacteria (i) may cooperate to degrade algal polysaccharides to products assimilable by the host or (ii) may have acquired these functions through gene transfer from the aerobic algal microbiota. PMID- 29587831 TI - Childhood fish oil supplementation modifies associations between traffic related air pollution and allergic sensitisation. AB - BACKGROUND: Studies of potential adverse effects of traffic related air pollution (TRAP) on allergic disease have had mixed findings. Nutritional studies to examine whether fish oil supplementation may protect against development of allergic disease through their anti-inflammatory actions have also had mixed findings. Extremely few studies to date have considered whether air pollution and dietary factors such as fish oil intake may interact, which was the rationale for this study. METHODS: We conducted a secondary analysis of the Childhood Asthma Prevention Study (CAPS) birth cohort, where children were randomised to fish oil supplementation or placebo from early life to age 5 years. We examined interactions between supplementation and TRAP (using weighted road density at place of residence as our measure of traffic related air pollution exposure) with allergic disease and lung function outcomes at age 5 and 8 years. RESULTS: Outcome information was available on approximately 400 children (~ 70% of the original birth cohort). Statistically significant interactions between fish oil supplementation and TRAP were seen for house dust mite (HDM), inhalant and all allergen skin prick tests (SPTs) and for HDM-specific interleukin-5 response at age 5. Adjusting for relevant confounders, relative risks (RRs) for positive HDM SPT were RR 1.74 (95% CI 1.22-2.48) per 100 m local road or 33.3 m of motorway within 50 m of the home for those randomised to the control group and 1.03 (0.76 1.41) for those randomised to receive the fish oil supplement. The risk differential was highest in an analysis restricted to those who did not change address between ages 5 and 8 years. In this sub-group, supplementation also protected against the effect of traffic exposure on pre-bronchodilator FEV1/FVC ratio. CONCLUSIONS: Results suggest that fish oil supplementation may protect against pro-allergic sensitisation effects of TRAP exposure. Strengths of this analysis are that supplementation was randomised and independent of TRAP exposure, however, findings need to be confirmed in a larger experimental study with the interaction investigated as a primary hypothesis, potentially also exploring epigenetic mechanisms. More generally, studies of adverse health effects of air pollution may benefit from considering potential effect modification by diet and other factors.

PMID- 29587832 TI - Community analysis of the abundance and diversity of biting midge species (Diptera: Ceratopogonidae) in three European countries at different latitudes. AB - BACKGROUND: The outbreaks of bluetongue and Schmallenberg disease in Europe have increased efforts to understand the ecology of Culicoides biting midges and their role in pathogen transmission. However, most studies have focused on a specific habitat, region, or country. To facilitate wider comparisons, and to obtain a better understanding of the spread of disease through Europe, the present study focused on monitoring biting midge species diversity in three different habitat types and three countries across Europe. METHODS: Biting midges were trapped using Onderstepoort Veterinary Institute light traps at a total of 27 locations in Sweden, the Netherlands and Italy, comprising farm, peri-urban and wetland habitats. From July 2014 to June 2015 all locations were sampled monthly, except for during the winter months. Trapped midges were counted and identified morphologically. Indices on species richness, evenness and diversity were calculated. Community compositions were analysed using non-metric multidimensional scaling (NMDS) techniques. RESULTS: A total of 50,085 female midges were trapped during 442 collection nights. More than 88% of these belonged to the Obsoletus group. The highest midge diversity was found in Sweden, while species richness was highest in the Netherlands, and most specimens were trapped in Italy. For habitats within countries, diversity of the trapped midges was lowest for farms in all countries. Differences in biting midge species communities were more distinct across the three countries than the three habitat types. CONCLUSIONS: A core midge community could be identified, in which the Obsoletus group was the most abundant. Variations in vector communities across countries imply different patterns of disease spread throughout Europe. How specific species and their associated communities affect disease risk is still unclear. Our results emphasize the importance of midge diversity data at community level, how this differs across large geographic range within Europe, and its implications on assessing risks of midge-borne disease outbreaks. PMID- 29587834 TI - A standard photomap of ovarian nurse cell chromosomes and inversion polymorphism in Anopheles beklemishevi. AB - BACKGROUND: Anopheles beklemishevi is a member of the Maculipennis group of malaria mosquitoes that has the most northern distribution among other members of the group. Although a cytogenetic map for the larval salivary gland chromosomes of this species has been developed, a high-quality standard cytogenetic photomap that enables genomics and population genetics studies of this mosquito at the adult stage is still lacking. METHODS: In this study, a cytogenetic map for the polytene chromosomes of An. beklemishevi from ovarian nurse cells was developed using high-resolution digital imaging from field collected mosquitoes. PCR amplified DNA probes for fluorescence in situ hybridization (FISH) were designed based on the genome of An. atroparvus. The DNA probe obtained by microdissection procedures from the breakpoint region was labelled in a DOP-PCR reaction. Population analysis was performed on 371 specimens collected in 18 locations. RESULTS: We report the development of a high-quality standard photomap for the polytene chromosomes from ovarian nurse cells of An. beklemishevi. To confirm the suitability of the map for physical mapping, several PCR-amplified probes were mapped to the chromosomes of An. beklemishevi using FISH. In addition, we identified and mapped DNA probes to flanking regions of the breakpoints of two inversions on chromosome X of this species. Inversion polymorphism was determined in 13 geographically distant populations of An. beklemishevi. Four polymorphic inversions were detected. The positions of common chromosomal inversions were indicated on the map. CONCLUSIONS: The study constructed a standard photomap for ovarian nurse cell chromosomes of An. beklemishevi and tested its suitability for physical genome mapping and population studies. Cytogenetic analysis determined inversion polymorphism in natural populations of An. beklemishevi related to this species' adaptation. PMID- 29587833 TI - Use of Hybrid Assistive Limb (HAL(r)) for a postoperative patient with cerebral palsy: a case report. AB - BACKGROUND: The Hybrid Assistive Limb (HAL(r)) is an exoskeleton wearable robot suit that assists in voluntary control of knee and hip joint motion. There have been several studies on HAL intervention effects in stroke, spinal cord injury, and cerebral palsy. However, no study has investigated HAL intervention for patients with cerebral palsy after surgery. CASE PRESENTATION: We report a case of using HAL in a postoperative patient with cerebral palsy. A 15-year-old boy was diagnosed with spastic diplegia cerebral palsy Gross Motor Function Classification System level IV, with knee flection contracture, equinus foot, and paralysis of the right upper extremity with adduction contracture. He underwent tendon lengthening of the bilateral hamstrings and Achilles tendons. Although the flexion contractures of the bilateral knees and equinus foot improved, muscle strength decreased after the soft tissue surgery. HAL intervention was performed twice during postoperative months 10 and 11. Walking speed, stride, and cadence were increased after HAL intervention. Post HAL intervention, extension angles of the knee in stance phase and hip in the pre-swing phase were improved. In the gait cycle, the proportion of terminal stance in the stance and swing phase was increased. CONCLUSIONS: Hybrid Assistive Limb intervention for postoperative patients with cerebral palsy whose muscle strength decreases can enhance improvement in walking ability. Further studies are needed to examine the safety and potential application of HAL in this setting. PMID- 29587835 TI - Is adjuvant chemotherapy beneficial for patients with FIGO stage IC adult granulosa cell tumor of the ovary? AB - BACKGROUND: To evaluate the association between adjuvant chemotherapy and clinical outcomes in patients with stage IC adult granulosa cell tumor (AGCT). METHODS: We performed a retrospective study of patients with stage IC AGCT diagnosed at our hospital from January 1985 to September 2015. We analyzed descriptive statistics, and performed univariate and multivariate and Kaplan Meier survival analyses. RESULTS: Sixty stage IC AGCT patients were identified, including 28 in the no adjuvant chemotherapy group (NACG) and 32 in the adjuvant chemotherapy group (ACG). The median follow-up time was 88 months (range: 9-334 months). Sixteen patients developed recurrences, including nine in the NACG and seven in the ACG groups. Univariate analysis identified incomplete surgical staging and initial treatment place as associated with disease-free survival (DFS) (P = 0.003 and 0.038, respectively). Incomplete surgical staging remained a risk factor for recurrence in multivariate analysis (hazard ratio (HR) = 3.883, 95% confidence interval (CI): 1.123-13.430, P = 0.032). The 5-year DFS rates in the NACG and ACG groups were 76.3% and 87.5% respectively (P = 0.197). Adjuvant chemotherapy was thus not associated with improved DFS. Furthermore, the number of chemotherapy cycles was not associated with recurrence rate (<=3 cycles vs. > 3 cycles, HR = 0.613, 95% CI: 0.112-3.351, P = 0.572). CONCLUSION: Administration of adjuvant chemotherapy does not improve DFS in patients with stage IC AGCT. Further studies with larger samples involving multi-institutional collaboration are needed to validate new treatment regimens for this disease. PMID- 29587836 TI - Atrophy of primary lymphoid organs induced by Marek's disease virus during early infection is associated with increased apoptosis, inhibition of cell proliferation and a severe B-lymphopenia. AB - Marek's disease is a multi-faceted highly contagious disease affecting chickens caused by the Marek's disease alphaherpesvirus (MDV). MDV early infection induces a transient immunosuppression, which is associated with thymus and bursa of Fabricius atrophy. Little is known about the cellular processes involved in primary lymphoid organ atrophy. Here, by in situ TUNEL assay, we demonstrate that MDV infection results in a high level of apoptosis in the thymus and bursa of Fabricius, which is concomitant to the MDV lytic cycle. Interestingly, we observed that in the thymus most of the MDV infected cells at 6 days post infection (dpi) were apoptotic, whereas in the bursa of Fabricius most of the apoptotic cells were uninfected suggesting that MDV triggers apoptosis by two different modes in these two primary lymphoid organs. In addition, a high decrease of cell proliferation was observed from 6 to 14 dpi in the bursa of Fabricius follicles, and not in the thymus. Finally, with an adapted absolute blood lymphocyte count, we demonstrate a major B-lymphopenia during the two 1st weeks of infection, and propose this method as a potent non-invasive tool to diagnose MDV bursa of Fabricius infection and atrophy. Our results demonstrate that the thymus and bursa of Fabricius atrophies are related to different cell mechanisms, with different temporalities, that affect infected and uninfected cells.

AB - BACKGROUND: The aim of the present paper was the assessment of the psychometric properties of the Polish language version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire applied in Poland among patients with type 1 (T1DM) or type 2 diabetes (T2DM). METHODS: The studies were carried out among 330 patients with diabetes including 115 with T1DM and 215 with T2DM. In all the patients the level of the quality of life was investigated using the Polish language version of the ADDQoL and the psychometric properties were determined taking into consideration internal consistency, the factor loading and intraclass correlations. RESULTS: It was demonstrated that the values of internal consistency determining the reliability of the Polish language version of the ADDQoL for the overall Cronbach's alfa coefficient were 0.92 in the studied patients with T1DM and 0.93 in the studied patients with T2DM and the values of the loading factor were respectively 0.39-0.79 and 0.35-0.81. In the study of the correlation between the components of the ADDQoL the correlation coefficients proved to be highly statistically significant: in patients with T1DM r = 0.46 0.74 and in patients with T2DM - r = 0.42-0.80. CONCLUSION: The Polish language version of the ADDQoL is a reliable tool useful for the assessment of the level of the quality of life of adult patients with T1DM or T2DM in Poland and is recommended to be used among Polish-speaking patients with diabetes. PMID- 29587837 TI - Checks and balances? DNA replication and the cell cycle in Plasmodium. AB - It is over 100 years since the life-cycle of the malaria parasite Plasmodium was discovered, yet its intricacies remain incompletely understood - a knowledge gap that may prove crucial for our efforts to control the disease. Phenotypic screens have partially filled the void in the antimalarial drug market, but as compound libraries eventually become exhausted, new medicines will only come from directed drug development based on a better understanding of fundamental parasite biology. This review focusses on the unusual cell cycles of Plasmodium, which may present a rich source of novel drug targets as well as a topic of fundamental biological interest. Plasmodium does not grow by conventional binary fission, but rather by several syncytial modes of replication including schizogony and sporogony. Here, we collate what is known about the various cell cycle events and their regulators throughout the Plasmodium life-cycle, highlighting the differences between Plasmodium, model organisms and other apicomplexan parasites and identifying areas where further study is required. The possibility of DNA replication and the cell cycle as a drug target is also explored. Finally the use of existing tools, emerging technologies, their limitations and future directions to elucidate the peculiarities of the Plasmodium cell cycle are discussed. PMID- 29587839 TI - Species identification approach for both raw materials and end products of herbal supplements from Tinospora species. AB - BACKGROUND: Nowadays herbal products used in traditional medicine are sold in processed forms and thus morphological authentication is almost impossible. With herbal industry rapidly growing size, consumer safety becomes an important issue that requires special attention. Identification of herbal species in the products is therefore needed. METHODS: Sequences from the selected regions (matK, rbcL, trnL and ITS1) were retrieved and analysed. Then the most suitable barcode was assessed for discrimination of T. crispa from closely related species by HRM analysis and used in authentication of commercial products. RESULTS: The ITS1 barcode was found to be the suitable primer as melting data from the HRM assay proved to be capable of distinguishing T. crispa from its related species. The developed protocol was then employed to authenticate medicinal products in powdered form. HRM analysis of all tested samples here revealed that five out of eight products contained not only the indicated species T. crispa but also other Tinospora, that have a high level of morphological similarity. CONCLUSION: Misrepresentation, poor packaging and inappropriate labeling of the tested medicinal herbal products are thought to be the reason of the results here. Using Bar-HRM with the ITS marker lead to success in authenticating the tested herbal products. PMID- 29587840 TI - Risk factors affecting the mortality of HIV-infected patients with pulmonary tuberculosis in the cART era: a retrospective cohort study in China. AB - BACKGROUND: Tuberculosis infection still places a great burden on HIV-infected individuals in China and other developing countries. Knowledge of the survival of HIV-infected patients with pulmonary tuberculosis (PTB) would provide important insights for the clinical management of this population, which remains to be well described in current China. METHODS: HIV-infected patients with PTB admitted to Shanghai Public Health Clinical Center from January 2011 to December 2015 were retrospectively enrolled. In this cohort, the survival prognosis was estimated by the Kaplan-Meier method, while univariate and multivariate Cox proportional hazards models were used to determine the risk factors affecting mortality. RESULTS: After reviewing 4914 admitted patients with HIV infection, 359 PTB cases were identified. At the time of PTB diagnosis, the patients' median CD4+ T cell count was 51 /mm3 (IQR: 23-116), and 27.30% of patients (98/359) were on combination antiretroviral therapy (cART). For the 333 cases included in the survival analysis, the overall mortality was 15.92% (53/333) during a median 27 month follow-up. The risk factors, including age older than 60 years (HR: 3.18; 95% CI: 1.66-6.10), complication with bacterial pneumonia (HR: 2.64; 95% CI: 1.30 5.35), diagnosis delay (HR: 2.60; 95% CI: 1.42-4.78), CD4+ T cell count less than 50/mm3 (HR: 2.38; 95% CI: 1.27-4.43) and pulmonary atelectasis (HR: 2.20; 95% CI: 1.05-4.60), might independently contribute to poor survival. Among patients without cART before anti-TB treatment, the later initiation of cART (more than 8 weeks after starting anti-TB treatment) was found to increase the mortality rate (OR: 4.33; 95% CI: 1.22-15.36), while the initiation of cART within 4-8 weeks after starting anti-TB treatment was associated with the fewest deaths (0/14). CONCLUSIONS: The subjects in this study conducted in the cART era were still characterized by depressed immunological competence and low rates of cART administration, revealing possible intervention targets for preventing TB reactivation in HIV-infected individuals under current circumstances. Furthermore, our study indicated that the timely diagnosis of PTB, prevention of secondary bacterial pneumonia by prophylactic management and optimization of the timing of cART initiation could have significant impacts on decreasing mortality among HIV/PTB co-infected populations. These findings deserve further prospective investigations to optimize the management of HIV/PTB-co-infected patients. TRIAL REGISTRATION: NCT01344148 , Registered September 14, 2010. PMID- 29587841 TI - Physical activity in the morning and afternoon is lower in patients with chronic obstructive pulmonary disease with morning symptoms. AB - BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) experience symptoms that vary over the day. Symptoms at the start of the day might influence physical activity during the rest of the day. Therefore, physical activity during the course of the day was studied in patients with low and high morning symptom scores. METHODS: This cross-sectional observational study included patients with moderate to very severe COPD. Morning symptoms were evaluated with the PRO morning COPD Symptoms Questionnaire (range 0-60); the median score was used to create two groups (low and high morning symptom scores). Physical activity was examined with an accelerometer. Activity parameters during the night, morning, afternoon and evening were compared between patients with low and high morning symptom scores using independent t-tests or Mann-Whitney U tests. RESULTS: Seventy nine patients were included. Patients were aged (mean +/- SD) 65.6 +/- 8.8 years with a mean forced expiratory volume in 1 s of 55 +/- 17%predicted. Patients with low morning symptom scores (score < 17.0) took more steps in the afternoon (p = 0.015) and morning (p = 0.030). There were no significant differences during the evening and night. CONCLUSION: Patients with high morning symptom scores took significantly fewer steps in the morning and afternoon than those with low morning symptom scores. Prospective studies are needed to prove causality between morning symptoms and physical activity during different parts of the day. PMID- 29587842 TI - Experimental infection of pigs with H1 and H3 influenza A viruses of swine by using intranasal nebulization. AB - BACKGROUND: Experimental infection of pigs via direct intranasal or intratracheal inoculation has been mainly used to study the infectious process of influenza A viruses of swine (IAVs-S). Nebulization is known to be an alternative method for inoculating pigs with IAVs-S, because larger quantities of virus potentially can be delivered throughout the respiratory tract. However, there is very little data on the experimental infection of pigs by inhalation using nebulizer. In the current study, we used intranasal nebulization to inoculate pigs with 9 different IAVs-S-3 H1N1, 2 H1N2, and 4 H3N2 strains. We then assessed the process of infection by evaluating the clinical signs, nasal and oral viral shedding, and seroconversion rates of the pigs inoculated. RESULTS: Lethargy and sneezing were the predominant clinical signs among pigs inoculated with 7 of the 9 strains evaluated; the remaining 2 strains (1 H1N1 and 1 H1N2 isolate) failed to induce any clinical signs throughout the experiments. Significantly increased rectal temperatures were observed with an H1N1 or H3N2 strains between 1 and 3 days post inoculation (dpi). In addition, patterns of nasal viral shedding differed among the strains: nasal viral shedding began on 1 dpi for 6 strains, with all 9 viruses being shed from 2 to 5 dpi. The detection of viral shedding was less sensitive from oral samples than nasal secretions. Viral shedding was not detected in either nasal or oral swabs after 10 dpi. According to hemagglutination-inhibition assays, all inoculated pigs had seroconverted to the inoculating virus by 14 dpi, with titers ranging from 10 to 320. CONCLUSIONS: Our current findings show that intranasal nebulization successfully established IAV-S infections in pigs and demonstrate that clinical signs, viral shedding, and host immune responses varied among the strains inoculated. PMID- 29587843 TI - Construct validity, test-retest reliability and internal consistency of the Thai version of the disabilities of the arm, shoulder and hand questionnaire (DASH-TH) in patients with carpal tunnel syndrome. AB - OBJECTIVE: This study evaluated additional psychometric properties of the Thai version of the disabilities of the arm, shoulder and hand questionnaire (DASH-TH) which included, test-retest reliability, construct validity, internal consistency of in patients with carpal tunnel syndrome. As for determining construct validity, the Thai EuroQOL questionnaire (EQ-5D-5L) was also administered in order to examine convergent and divergent validity. RESULTS: Fifty patients completed both questionnaires. The DASH-TH showed excellent test-retest reliability (intraclass correlation coefficient = 0.811) and internal consistency (Cronbach's alpha = 0.911). The exploratory factor analysis yielded a six-factor solution while the confirmatory factor analysis denoted that the hypothesized model adequately fit the data with a comparative fit index of 0.967 and a Tucker Lewis index of 0.964. The related subscales between the DASH-TH and the Thai EQ 5D-5L were significantly correlated, indicating the DASH-TH's convergent and discriminant validity. The DASH-TH demonstrated good reliability, internal consistency construct validity, and multidimensionality, in assessing the upper extremity function in carpal tunnel syndrome patients. PMID- 29587844 TI - From river blindness control to elimination: bridge over troubled water. AB - BACKGROUND: An estimated 25 million people are currently infected with onchocerciasis (a parasitic infection caused by the filarial nematode Onchocerca volvulus and transmitted by Simulium vectors), and 99% of these are in sub Saharan Africa. The African Programme for Onchocerciasis Control closed in December 2015 and the World Health Organization has established a new structure, the Expanded Special Project for the Elimination of Neglected Tropical Diseases for the coordination of technical support for activities focused on five neglected tropical diseases in Africa, including onchocerciasis elimination. AIMS: In this paper we argue that despite the delineation of a reasonably well defined elimination strategy, its implementation will present particular difficulties in practice. We aim to highlight these in an attempt to ensure that they are well understood and that effective plans can be laid to solve them by the countries concerned and their international partners. CONCLUSIONS: A specific concern is the burden of disease caused by onchocerciasis-associated epilepsy in hyperendemic zones situated in countries experiencing difficulties in strengthening their onchocerciasis control programmes. These difficulties should be identified and programmes supported during the transition from morbidity control to interruption of transmission and elimination. PMID- 29587845 TI - Patient-derived lymphoblastoid cell lines harboring mitochondrial DNA mutations as tool for small molecule drug discovery. AB - OBJECTIVE: Mitochondrial diseases are a group of devastating disorders for which there is no transformative cure. The majority of therapies for mitochondrial disease-approved, previously tested, or currently in development-are small molecules. The implementation of better cell-based models of mitochondrial disease can accelerate and improve the accuracy of small molecule drug discovery. The objective of this study is to evaluate the use of patient-derived lymphoblastoid cell lines for small molecule research in mitochondrial disease. RESULTS: Five lymphoblastoid cell lines derived from mitochondrial disease patients harboring point mutations in mtND1, mtND4, or mtATP6 were characterized in two high throughput assays assessing mitochondrial function. In a pilot "clinical trial in a dish" experiment, the efficacy of idebenone-an approved therapy for mitochondrial disease-on the lymphoblastoid cell lines was tested. Idebenone increased the basal respiration of all lymphoblastoid cell lines except those harboring the 8993T>G point mutation in mtATP6. Our results posit lymphoblastoid cell lines as a strong model for mitochondrial disease research with small molecules and have implications for the clinical efficacy of idebenone. PMID- 29587846 TI - Evaluation of two DNA extraction methods for the PCR-based detection of eukaryotic enteric pathogens in fecal samples. AB - OBJECTIVE: Efficient and easy-to-use DNA extraction and purification methods are critical in implementing PCR-based diagnosis of pathogens. In order to optimize the routine clinical laboratory diagnosis of eukaryotic enteric pathogens, we compare, via quantitative PCR cycle threshold (Ct) values, the efficiency of two DNA extraction kits: the semi-automated EZ1(r) (Qiagen) and the manual QIAamp(r) DNA Stool Mini Kit (Qiagen), on six protozoa: Blastocystis spp., Cryptosporidium parvum/hominis, Cyclospora cayetanensis, Dientamoeba fragilis, Giardia intestinalis and Cystoisospora belli and one microsporidia: Enterocytozoon bieneusi. RESULTS: Whereas EZ1(r) (Qiagen) and QIAamp(r) DNA Stool Mini Kit (Qiagen) yielded similar performances for the detection of Cryptosporidium spp. and D. fragilis, significant lower Ct values (p < 0.002) pointed out a better performance of EZ1(r) on the five remaining pathogens. DNA extraction using the semi-automated EZ1(r) procedure was faster and as efficient as the manual procedure in the seven eukaryotic enteric pathogens tested. This procedure is suitable for DNA extraction from stools in both clinical laboratory diagnosis and epidemiological study settings. PMID- 29587848 TI - Cytokeratin 5/6 expression in bladder cancer: association with clinicopathologic parameters and prognosis. AB - OBJECTIVES: Well differentiated keratinized squamous component as a part of urothelial carcinoma can be easily appreciated; however non-keratinizing squamous differentiation closely resembles urothelial differentiation. In addition prognostic significance of CK 5/6 expression in the absence of apparent squamous differentiation is still unclear. Therefore, in the present study we aimed to evaluate the frequency of CK 5/6 expression in 127 cases of urothelial carcinoma and its prognostic significance in loco-regional population. RESULTS: Positive CK5/6 expression was noted in 6.3% (8 cases) and 13.4% (17 cases) revealed focal positive CK 5/6 expression. On the other hand, 80.3% (102 cases) showed negative CK5/6 staining. Significant association of CK5/6 expression was noted with tumor grade and muscularis propria invasion, however no significant association was noted with overall and disease free survival. On the basis of the results of our study we can conclude that CK5/6 is an independent prognostic biomarker in urothelial carcinoma and therefore can be used in the prognostic stratification of the patients with bladder cancer. PMID- 29587847 TI - High-sensitivity virus and mycoplasma screening test reveals high prevalence of parvovirus B19 infection in human synovial tissues and bone marrow. AB - BACKGROUND: Latent microorganism infection is a safety concern for the clinical application of mesenchymal stem cells (MSCs). The aim of this study is to investigate the frequencies and sensitivities of the latent virus and mycoplasma infections in synovium, bone marrow, peripheral blood cells, and blood plasma and cultured synovial MSCs. METHODS: Total DNA and RNA of the synovium (n = 124), bone marrow (n = 123), peripheral blood cells (n = 121), plasma (n = 121), and 14 day cultured synovial MSCs (n = 63) were collected from patients who underwent total knee arthroplasty or anterior ligament reconstruction after written informed consents were obtained. The multiplex polymerase chain reaction (PCR) primers were designed to quantitatively measure the representative genomes of 13 DNA viruses, 6 RNA viruses, and 9 mycoplasmas. Multi-spliced mRNA detection and virus spike test were also performed to demonstrate the sensitivity of synovial MSCs to the candidate pathogens. RESULTS: In synovium and bone marrow, the positive rates of parvovirus B19 genome were significantly higher than in peripheral blood cells (18.7% and 22% vs. 0.8%, respectively). Multi-alignment analysis of amplified and sequenced viral target genes showed the proximity of the parvovirus B19 gene from different tissue in the same patients. Synovial MSCs cultured for 14 days were positive for virus infection only in two patients (2/62 = 3%). Parvovirus B19 multi-spliced mRNAs were not detected in these two samples. Virus spike test demonstrated the sensitivity of synovial MSCs to herpes simplex virus (HSV)1 and cytomegalovirus (CMV), but not to parvovirus B19. CONCLUSION: This study revealed a relatively high incidence of latent parvovirus B19 in synovium and bone marrow tissue. PMID- 29587849 TI - Serological survey in wild boar (Sus scrofa) in Switzerland and other European countries: Sarcoptes scabiei may be more widely distributed than previously thought. AB - BACKGROUND: Sarcoptic mange has recently emerged in wild boar in Switzerland, raising the question of the origin of the infection. The main aim of this study was to assess the extent of exposure of the wild boar populations to Sarcoptes scabiei in Switzerland, prior to and after the detection of mange cases, to determine whether the mite has been recently introduced into the populations concerned. We performed a serological survey using a commercially available ELISA and 1056 archived blood samples of free-ranging wild boar from Switzerland. To facilitate the interpretation of the obtained data, we additionally estimated seroprevalence in wild boar populations of four other European countries (1060 samples), both from areas with confirmed clinical cases of mange and from areas without reported cases in wild boar. Lastly, we revised the evaluation of the commercial ELISA when used with wild boar sera. RESULTS: Seropositive reactions were observed for samples from all five countries and from 15 of the 16 study areas. The obtained apparent seroprevalences ranged from 0.0% (0/82; 95% confidence interval [CI]: 0.0-4.4) to 17.4% (8/46; 95% CI: 7.8-31.4). Wild boar from study areas with known clinical cases and those <=60 kg were four times more likely to be seropositive than wild boar from areas without reported cases and > 60 kg, respectively. Optical density values did not differ between the two types of study areas among seropositive samples but were significantly lower among seronegative samples from areas without than from areas with clinical cases. No difference was observed between the two sampling periods in Switzerland. The revised ELISA specificity was 96.8% (984/1017; 95% CI: 95.5-97.7) when wild boar from areas without history of mange were considered truly negative. CONCLUSIONS: Seropositivity to S. scabiei is more frequent and occurs over a larger geographic range than expected. Data suggest that the parasite is endemic within the wild boar populations of Switzerland and other European countries but that its presence is not necessarily associated with disease occurrence. Extrinsic factors which trigger disease emergence in infected populations remain to be investigated. The applied ELISA represents a promising tool for future studies. PMID- 29587851 TI - Clinical and MRI remission in patients with nonradiographic axial spondyloarthritis who received long-term open-label adalimumab treatment: 3-year results of the ABILITY-1 trial. AB - BACKGROUND: Adalimumab was effective in treating patients with nonradiographic axial spondyloarthritis (nr-axSpA) in the 12-week ABILITY-1 trial. We present long-term efficacy and safety results of adalimumab from the open-label ABILITY-1 extension, including the relationship between clinical and magnetic resonance imaging (MRI) remission and impact of sustained clinical remission on physical function. METHODS: Patients received adalimumab 40 mg every other week or placebo for 12 weeks, then open-label adalimumab for up to 144 weeks. Clinical and safety data were collected through 3 years, and MRI data were collected until 2 years. Analyses were performed in the total population and subpopulation with positive MRI and/or elevated C-reactive protein (MRI/CRP-positive) at baseline. Clinical and MRI remission definitions included Ankylosing Spondylitis Disease Activity Score inactive disease (ASDAS ID; score < 1.3) and Spondyloarthritis Research Consortium of Canada (SPARCC) MRI score < 2 for sacroiliac joints (SIJs), spine, or both. Physical function was assessed using the Bath Ankylosing Spondylitis Functional Index. RESULTS: Overall, 185 patients were included in the total population and 142 in the MRI/CRP-positive subpopulation; 65% and 68%, respectively, completed 3 years. Clinical, functional, and MRI improvements were similar and equally sustainable in both populations. At year 3, the percentages of patients in ASDAS ID in the MRI/CRP-positive subpopulation were 30%/33% (nonresponder imputation) and 46%/49% (observed) for those initially receiving adalimumab/placebo. At years 1 and 2, patients in ASDAS ID vs not had significantly greater improvements in SPARCC SIJ scores from baseline (P < 0.001). Among patients with baseline MRI scores >= 2 who achieved ASDAS ID at year 2, 44-68% also had MRI remission. Significantly more patients with sustained ASDAS ID through year 2 or 3 vs without achieved normal physical function (100% vs 48%; 100% vs 44%; both P < 0.001). No new safety concerns were observed. CONCLUSIONS: In the ABILITY-1 study of nr-axSpA, adalimumab therapy provided sustained clinical and functional improvements through 3 years, as well as suppression of MRI axial inflammation, which was greater in patients who achieved clinical remission. Sustained clinical remission was associated with increased attainment of normal physical function. The safety profile of adalimumab was consistent with prior studies.

PMID- 29587850 TI - Investigation of temperature conditions in Swiss urban and suburban microhabitats for the overwintering suitability of diapausing Aedes albopictus eggs. AB - BACKGROUND: In Switzerland, the invasive Asian tiger mosquito, Aedes albopictus, is firmly established in the Canton of Ticino, south of the Alps. According to a large-scale distribution model developed in 2013, suitable climatic conditions for the establishment of Ae. albopictus north of the Alps are found in Basel and Geneva while Zurich appears to be characterized by winters currently being too cold for survival of diapausing eggs. However, the spatial resolution of large scale distribution models might not be sufficient to detect particular climatic conditions existing in urban settings, such as the presence of microclimatic temperatures, which may positively influence the probability of diapausing eggs to overwinter. In order to investigate this, microclimatic monitoring of potential diapausing sites (i.e. catch basins) and external controls was performed in January 2017 in Ticino and within the cities of Basel, Geneva and Zurich. RESULTS: Mean January temperatures in catch basins of Basel, Geneva and Zurich were always higher than the -1 degrees C temperature threshold previously set for survival probability of diapausing eggs, while mean January temperatures were below -1 degrees C in several catch basins south of the Alps, where Ae. albopictus eggs currently overwinter. The catch basin absolute January daily minimum temperatures both south and north of the Alps were in general higher than the external control temperatures. Absolute January daily minimum temperatures in catch basins in Basel, Geneva and Zurich were always above -10 degrees C, indicating that diapausing Ae. albopictus eggs could potentially survive winter nights in urban areas north of the Alps. CONCLUSIONS: The findings confirmed previous conclusions that urban catch basins can provide favourable conditions for overwintering of diapausing eggs compared to more cold-exposed sites. The results confirmed the presence of suitable winter conditions for the establishment of Ae. albopictus in the cities of Basel and Geneva. In addition, the microclimate-scale analysis added new information compared to the previous large-scale prevision model by showing that also the city of Zurich could provide winter conditions suitable for the establishment of Ae. albopictus. This illustrates the importance of the resolution of climate data in using models to predict Ae. albopictus distribution. PMID- 29587852 TI - Repair of bone defects in rat radii with a composite of allogeneic adipose derived stem cells and heterogeneous deproteinized bone. AB - BACKGROUND: In the bone tissue engineering domain, seed cells, scaffold and cell scaffold composites are three focuses. In this study, the feasibility of using allogeneic adipose-derived stem cells(ADSCs) combined with heterogeneous deproteinized bone (HDB) to repair segmental radial defects was investigated by observing the repair of the defect area. METHODS: ADSCs were cultured in vitro, purified, antigen-detected and osteogenic differentiation potency-measured; then, the ADSCs of the third generation were seeded into HDB to prepare an ADSCs-HDB composite partly with osteogenesis induced cells. Sixty Wistar rats were randomly divided into four groups with 15 in each group. A bone defect (4 mm in length) was created at the left radius in each rat. Two kinds of ADSCs-HDB composites were implanted in the ADSCs osteogenesis group or ADSCs group; HDB was implanted in the negative control group; nothing was filled in the blank control group. The bone defect repair was evaluated by gross observation, molybdenum target X-ray examination and histological analyses after surgery. RESULTS: Gross observation: the bone defect area was completely filled and difficult to recognize in the ADSCs osteogenesis group. The connection of the ADSCs group was strong, but the implants were clearly identifiable. The joints of the negative control group were slightly thick but the connection was unstable. In the blank control group, kermesinus tissue was between the two ends and bones were not connected after 8 weeks. Molybdenum target X-ray examinations: In the ADSCs osteogenesis group, evident bridges in the graft were observed in the defects in the fourth week; the defects were filled with new bone completely and a marrow cavity appeared at 8 weeks. In the ADSCs group, there were some callus formations, but the radial defect was still obvious at 8 weeks. In the negative control group, fracture lines were clear. In the blank control group, no osseous bridges were observed, which resulted in bone nonunion eventually in 8 weeks. There were significant differences in the callus density between experimental groups and the blank control group at 4 and 8 weeks (P < 0.01). Histological measures showed that the rate and quality of the new bone formation and remodelling was significantly different between the experimental and control groups. CONCLUSIONS: A composite of ADSCs-HDB has a strong osteogenic ability. It can repair segmental bone defects well and is promising to serve as grafting material in bone tissue engineering. PMID- 29587854 TI - Large-scale discovery of previously undetected microRNAs specific to human liver. AB - MicroRNAs (miRNAs) are crucial regulators of gene expression in normal development and cellular homeostasis. While miRNA repositories contain thousands of unique sequences, they primarily contain molecules that are conserved across several tissues, largely excluding lineage and tissue-specific miRNAs. By analyzing small non-coding RNA sequencing data for abundance and secondary RNA structure, we discovered 103 miRNA candidates previously undescribed in liver tissue. While expression of some of these unannotated sequences is restricted to non-malignant tissue, downregulation of most of the sequences was detected in liver tumors, indicating their importance in the maintenance of liver homeostasis. Furthermore, target prediction revealed the involvement of the unannotated miRNA candidates in fatty-acid metabolism and tissue regeneration, which are key pathways in liver biology. Here, we provide a comprehensive analysis of the undiscovered liver miRNA transcriptome, providing new resources for a deeper exploration of organ-specific biology and disease. PMID- 29587853 TI - What do randomized controlled trials say about virtual rehabilitation in stroke? A systematic literature review and meta-analysis of upper-limb and cognitive outcomes. AB - BACKGROUND: Virtual-reality based rehabilitation (VR) shows potential as an engaging and effective way to improve upper-limb function and cognitive abilities following a stroke. However, an updated synthesis of the literature is needed to capture growth in recent research and address gaps in our understanding of factors that may optimize training parameters and treatment effects. METHODS: Published randomized controlled trials comparing VR to conventional therapy were retrieved from seven electronic databases. Treatment effects (Hedge's g) were estimated using a random effects model, with motor and functional outcomes between different protocols compared at the Body Structure/Function, Activity, and Participation levels of the International Classification of Functioning. RESULTS: Thirty-three studies were identified, including 971 participants (492 VR participants). VR produced small to medium overall effects (g = 0.46; 95% CI: 0.33-0.59, p < 0.01), above and beyond conventional therapies. Small to medium effects were observed on Body Structure/Function (g = 0.41; 95% CI: 0.28-0.55; p < 0.01) and Activity outcomes (g = 0.47; 95% CI: 0.34-0.60, p < 0.01), while Participation outcomes failed to reach significance (g = 0.38; 95% CI: -0.29 1.04, p = 0.27). Superior benefits for Body Structure/Function (g = 0.56) and Activity outcomes (g = 0.62) were observed when examining outcomes only from purpose-designed VR systems. Preliminary results (k = 4) suggested small to medium effects for cognitive outcomes (g = 0.41; 95% CI: 0.28-0.55; p < 0.01). Moderator analysis found no advantage for higher doses of VR, massed practice training schedules, or greater time since injury. CONCLUSION: VR can effect significant gains on Body Structure/Function and Activity level outcomes, including improvements in cognitive function, for individuals who have sustained a stroke. The evidence supports the use of VR as an adjunct for stroke rehabilitation, with effectiveness evident for a variety of platforms, training parameters, and stages of recovery. PMID- 29587856 TI - Global Health as "umbrella term" - a qualitative study among Global Health teachers in German medical education. AB - BACKGROUND: The increasing impact of globalisation on healthcare demands new knowledge, skills and attitudes from healthcare professionals. One consequence of this is the rise of Global Health (GH) programs in health education all over the world. In Germany no consensus exists on what GH is and how it should be taught. This study used a grounded theory approach. We conducted eleven in-depth interviews with GH teachers in German medical education to ask them about their views on Global Health and the approaches they took in teaching these topics. Data collection and Analysis informed each other and followed an inductive approach. RESULTS: Our research identified three major questions: (1) What is GH? (2) What belongs to GH? (3) How can GH be taught? A central finding of our study is the understanding of GH as an umbrella term. We show how this understanding helps clarify the relation between GH and Public Health, International Health and Tropical medicine. At the core of GH we see the supraterritorial determinants of health. Surrounding the core, we describe a wide variety of topics that are a facultative, but not necessarily a compulsory part GH. One of the key characteristics of GH within all its aspects is its multidisciplinary nature. Based on this understanding we present models about the content of GH, how it can be taught and how GH teaching improves and strengthens overall medical education. CONCLUSIONS: This is to our knowledge the first study that conducts in-depth interviews with GH teachers to explore the practical understanding of GH in medical education. While the generalisability of our results needs to be subject of further research, the models presented can help shape the future discourse around GH and its integration into medical education. PMID- 29587855 TI - Assessment of microbiome changes after rumen transfaunation: implications on improving feed efficiency in beef cattle. AB - BACKGROUND: Understanding the host impact on its symbiotic microbiota is important in redirecting the rumen microbiota and thus improving animal performance. The current study aimed to understand how rumen microbiota were altered and re-established after being emptied and receiving content from donor, thus to understand the impact of such process on rumen microbial fermentation and to explore the microbial phylotypes with higher manipulation potentials. RESULTS: Individual animal had strong effect on the re-establishment of the bacterial community according to the observed profiles detected by both fingerprinting and pyrosequencing. Most of the bacterial profile recovery patterns and extents at genus level varied among steers; and each identified bacterial genus responded to transfaunation differently within each host. Coriobacteriaceae, Coprococcus, and Lactobacillus were found to be the most responsive and tunable genera by exchanging rumen content. Besides, the association of 18 bacterial phylotypes with host fermentation parameters suggest that these phylotypes should also be considered as the regulating targets in improving host feed efficiency. In addition, the archaeal community had different re-establishment patterns for each host as determined by fingerprint profiling: it was altered after receiving non native microbiome in some animals, while it resumed its original status after the adaptation period in the other ones. CONCLUSIONS: The highly individualized microbial re-establishment process suggested the importance of considering host genetics, microbial functional genomics, and host fermentation/performance assessment when developing effective and selective microbial manipulation methods for improving animal feed efficiency. PMID- 29587857 TI - HSP70 from the Antarctic sea urchin Sterechinus neumayeri: molecular characterization and expression in response to heat stress. AB - BACKGROUND: Heat stress proteins are implicated in stabilizing and refolding denatured proteins in vertebrates and invertebrates. Members of the Hsp70 gene family comprise the cognate heat shock protein (Hsc70) and inducible heat shock protein (Hsp70). However, the cDNA sequence and the expression of Hsp70 in the Antarctic sea urchin are unknown. METHODS: We amplified and cloned a transcript sequence of 1991 bp from the Antarctic sea urchin Sterechinus neumayeri, experimentally exposed to heat stress (5 and 10 degrees C for 1, 24 and 48 h). RACE-PCR and qPCR were employed to determine Hsp70 gene expression, while western blot and ELISA methods were used to determine protein expression. RESULTS: The sequence obtained from S. neumayeri showed high identity with Hsp70 members. Several Hsp70 family features were identified in the deduced amino acid sequence and they indicate that the isolated Hsp70 is related to the cognate heat shock protein type. The corresponding 70 kDa protein, called Sn-Hsp70, was immune detected in the coelomocytes and the digestive tract of S. neumayeri using a monospecific polyclonal antibody. We showed that S. neumayeri do not respond to acute heat stress by up-regulation of Sn-Hsp70 at transcript and protein level. Furthermore, the Sn-Hsp70 protein expression was not induced in the digestive tract. CONCLUSIONS: Our results provide the first molecular evidence that Sn Hsp70 is expressed constitutively and is non-induced by heat stress in S. neumayeri. PMID- 29587858 TI - HLA and proteasome expression body map. AB - BACKGROUND: The presentation of HLA peptide complexes to T cells is a highly regulated and tissue specific process involving multiple transcriptionally controlled cellular components. The extensive polymorphism of HLA genes and the complex composition of the proteasome make it difficult to map their expression profiles across tissues. METHODS: Here we applied a tailored gene quantification pipeline to 4323 publicly available RNA-Seq datasets representing 55 normal tissues and cell types to examine expression profiles of (classical and non classical) HLA class I, class II and proteasomal genes. RESULTS: We generated the first comprehensive expression atlas of antigen presenting-related genes across 56 normal tissues and cell types, including immune cells, pancreatic islets, platelets and hematopoietic stem cells. We found a surprisingly heterogeneous HLA expression pattern with up to 100-fold difference in intra-tissue median HLA abundances. Cells of the immune system and lymphatic organs expressed the highest levels of classical HLA class I (HLA-A,-B,-C), class II (HLA-DQA1,-DQB1,-DPA1, DPB1,-DRA,-DRB1) and non-classical HLA class I (HLA-E,-F) molecules, whereas retina, brain, muscle, megakaryocytes and erythroblasts showed the lowest abundance. In contrast, we identified a distinct and highly tissue-restricted expression pattern of the non-classical class I gene HLA-G in placenta, pancreatic islets, pituitary gland and testis. While the constitutive proteasome showed relatively constant expression across all tissues, we found the immunoproteasome to be enriched in lymphatic organs and almost absent in immune privileged tissues. CONCLUSIONS: Here, we not only provide a reference catalog of tissue and cell type specific HLA expression, but also highlight extremely variable expression of the basic components of antigen processing and presentation in different cell types. Our findings indicate that low expression of classical HLA class I molecules together with lack of immunoproteasome components as well as upregulation of HLA-G may be of key relevance to maintain tolerance in immune privileged tissues. PMID- 29587859 TI - Characterization of tri and tetra-nucleotide microsatellite loci for the freshwater snails Promenetus exacuous (Planorbidae) and Valvata tricarinata (Valvatidae) and their utility in population genetic studies. AB - OBJECTIVE: Promenetus exacuous and Valvata tricarinata are freshwater snail species with widespread distributions throughout North America. Information regarding their genetic diversity and population connectivity are currently lacking. We utilized next generation sequencing to develop the first microsatellites for each species to investigate genetic diversity within and differentiation among populations. RESULTS: Sixteen and seventeen microsatellite loci were developed for P. exacuous and V. tricarinata, respectively, and tested in a total of 43 P. exacuous and 48 V. tricarinata from two lakes approximately 183 km apart in New York State, USA. Fifteen P. exacuous loci were polymorphic in at least one lake and possessed 1-23 alleles and observed heterozygosities of 0.00-0.96 within individual lakes. Seventeen polymorphic V. tricarinata loci possessed 2-19 alleles and observed heterozygosities of 0.04-0.96 within lakes. Bayesian clustering using 12 loci for each species identified two distinct genetic populations, reflecting the two lakes. High assignment scores for individual snails to the lakes they were collected from supported strong population structure with minimal admixture at the scale of this study. These loci will be useful for investigating the genetic diversity and population structure of these species and indicate genetic differentiation may be common among their populations. PMID- 29587860 TI - Roles of astrocytic connexin-43, hemichannels, and gap junctions in oxygen glucose deprivation/reperfusion injury induced neuroinflammation and the possible regulatory mechanisms of salvianolic acid B and carbenoxolone. AB - BACKGROUND: Glia-mediated neuroinflammation is related to brain injury exacerbation after cerebral ischemia/reperfusion (I/R) injury. Astrocytic hemichannels or gap junctions, which were mainly formed by connexin-43, have been implicated in I/R damage. However, the exact roles of astrocytic hemichannels and gap junction in neuroinflammatory responses induced by I/R injury remain unknown. METHODS: Primary cultured astrocytes were subjected to OGD/R injury, an in vitro model of I/R injury. Salvianolic acid B (SalB) or carbenoxolone (CBX) were applied for those astrocytes. Besides, Cx43 mimetic peptides Gap19 or Gap26 were also applied during OGD/R injury; Cx43 protein levels were determined by western blot and cytoimmunofluorescene staining, hemichannel activities by Ethidium bromide uptake and ATP concentration detection, and gap junction intercellular communication (GJIC) permeability by parachute assay. Further, astrocyte conditioned medium (ACM) was collected and incubated with microglia. Meanwhile, ATP or apyrase were applied to explore the role of ATP during OGD/R injury. Microglial activation, M1/M2 phenotypes, and M1/M2-related cytokines were detected. Also, microglia-conditioned medium (MEM) was collected and incubated with astrocytes to further investigate its influence on astrocytic hemichannel activity and GJIC permeability. Lastly, effects of ACM and MCM on neuronal viability were detected by flow cytometry. RESULTS: We found that OGD/R induced abnormally opened hemichannels with increased ATP release and EtBr uptake but reduced GJIC permeability. WB tests showed decreased astrocytic plasma membrane's Cx43, while showing an increase in cytoplasma. Treating OGD/R-injured microglia with ATP or OGD/R-ACM induced further microglial activation and secondary pro inflammatory cytokine release, with the M1 phenotype predominating. Conversely, astrocytes incubated with OGD/R-MCM exhibited increased hemichannel opening but reduced GJIC coupling. Both SalB and CBX inhibited abnormal astrocytic hemichannel opening and ATP release and switched the activated microglial phenotype from M1 to M2, thus providing effective neuroprotection. Application of Gap19 or Gap26 showed similar results with CBX. We also found that OGD/R injury caused both plasma membrane p-Cx43(Ser265) and p-Src(Tyr416) significantly upregulated; application of SalB may be inhibiting Src kinase and attenuating Cx43 internalization. Meanwhile, CBX treatment induced obviously downregulation of p-Cx43(Ser368) and p-PKC(Ser729) protein levels in plasma membrane. CONCLUSIONS: We propose a vicious cycle exists between astrocytic hemichannel and microglial activation after OGD/R injury, which would aggravate neuroinflammatory responses and neuronal damage. Astrocytic Cx43, hemichannels, and GJIC play critical roles in OGD/R injury-induced neuroinflammatory responses; treatment differentially targeting astrocytic Cx43, hemichannels, and GJIC may provide novel avenues for therapeutics during cerebral I/R injury. PMID- 29587861 TI - Pretreatment with coenzyme Q10 improves ovarian response and embryo quality in low-prognosis young women with decreased ovarian reserve: a randomized controlled trial. AB - BACKGROUND: Management of women with reduced ovarian reserve or poor ovarian response (POR) to stimulation is one of the major challenges in reproductive medicine. The primary causes of POR remain elusive and oxidative stress was proposed as one of the important contributors. It has been suggested that focus on the specific subpopulations within heterogeneous group of poor responders could assist in evaluating optimal management strategies for these patients. This study investigated the effect of anti-oxidant treatment with coenzyme Q10 (CoQ10) on ovarian response and embryo quality in young low-prognosis patients with POR. METHODS: This prospective, randomized controlled study included 186 consecutive patients with POR stratified according to the POSEIDON classification group 3 (age < 35, poor ovarian reserve parameters). The participants were randomized to the CoQ10 pre-treatment for 60 days preceding IVF-ICSI cycle or no pre-treatment. The number of high quality embryos was a primary outcome measure. RESULTS: A total of 169 participants were evaluated (76 treated with CoQ10 and 93 controls); 17 women were excluded due to low compliance with CoQ10 administration. The baseline demographic and clinical characteristics were comparable between the groups. CoQ10 pretreatment resulted in significantly lower gonadotrophin requirements and higher peak E2 levels. Women in CoQ10 group had increased number of retrieved oocytes (4, IQR 2-5), higher fertilization rate (67.49%) and more high-quality embryos (1, IQR 0-2); p < 0.05. Significantly less women treated with CoQ10 had cancelled embryo transfer because of poor embryo development than controls (8.33% vs. 22.89%, p = 0.04) and more women from treatment group had available cryopreserved embryos (18.42% vs. 4.3%, p = 0.012). The clinical pregnancy and live birth rates per embryo transfer and per one complete stimulation cycle tended to be higher in CoQ10 group but did not achieve statistical significance. CONCLUSION: Pretreatment with CoQ10 improves ovarian response to stimulation and embryological parameters in young women with poor ovarian reserve in IVF-ICSI cycles. Further work is required to determine whether there is an effect on clinical treatment endpoints. PMID- 29587862 TI - Trauma facilities in Denmark - a nationwide cross-sectional benchmark study of facilities and trauma care organisation. AB - BACKGROUND: Trauma is a leading cause of death among adults aged < 44 years, and optimal care is a challenge. Evidence supports the centralization of trauma facilities and the use multidisciplinary trauma teams. Because knowledge is sparse on the existing distribution of trauma facilities and the organisation of trauma care in Denmark, the aim of this study was to identify all Danish facilities that care for traumatized patients and to investigate the diversity in organization of trauma management. METHODS: We conducted a systematic observational cross-sectional study. First, all hospitals in Denmark were identified via online services and clarifying phone calls to each facility. Second, all trauma care manuals on all facilities that receive traumatized patients were gathered. Third, anesthesiologists and orthopedic surgeons on call at all trauma facilities were contacted via telephone for structured interviews. RESULTS: A total of 22 facilities in Denmark were found to receive traumatized patients. All facilities used a trauma care manual and all had a multidisciplinary trauma team. The study found three different trauma team activation criteria and nine different compositions of teams who participate in trauma care. Training was heterogeneous and, beyond the major trauma centers, databases were only maintained in a few facilities. CONCLUSION: The study established an inventory of the existing Danish facilities that receive traumatized patients. The trauma team activation criteria and the trauma teams were heterogeneous in both size and composition. A national database for traumatized patients, research on nationwide trauma team activation criteria, and team composition guidelines are all called for. PMID- 29587863 TI - Chinese herbal medicine Shenzhuo Formula treatment in patients with macroalbuminuria secondary to diabetic kidney disease: study protocol for a randomized controlled trial. AB - BACKGROUND: Diabetic kidney disease (DKD) is a serious complication associated with diabetes mellitus and can cause end-stage renal disease (ESRD). Traditional Chinese medicine (TCM) is widely used in China to treat DKD, and in particular microalbuminuria and macroalbuminuria. This study will address the efficacy and safety of Shenzhuo Formula (SZF), a frequently prescribed TCM, in DKD patients with macroalbuminuria. METHODS/DESIGN: This study is a 24-week, randomized, multi center, double-blinded, double-dummy, controlled, clinical trial that will include 120 DKD patients aged 18 to 80 years old with a 24-h urinary protein (24 h UP) level of between 0.5 g and 3 g and serum creatinine (SCr) <= 133 MUmol/L (1.5 mg/dL) and compare SZF to irbesartan. The 24-h UP change from baseline to week 24 will represent the primary endpoint with secondary endpoints including SCr, estimated glomerular filtration rate (eGFR), TCM symptoms, urinary albumin excretion rate (UAER), etc. Safety assessments will also be evaluated. DISCUSSION: This study will provide initial evidence regarding the efficacy and safety of SZF relative to irbesartan in the treatment of DKD patients with macroalbuminuria.

PMID- 29587865 TI - Distinctive features of immunostaining and mutational load in primary pulmonary enteric adenocarcinoma: implications for differential diagnosis and immunotherapy. AB - BACKGROUND: Primary pulmonary enteric adenocarcinoma (PEAC) is an extremely rare variant of invasive lung cancer. It is highly heterogeneous while shares some common morphologic and immunohistochemical features with usual pulmonary adenocarcinoma (PAC) and colorectal adenocarcinoma (CRAC), making the differential diagnosis difficult. At present there are only limited studies about distinctive features of primary PEAC and the results are often inconsistent. METHODS: We retrospectively analyzed total 129 primary PEACs and 50 CRACs that were published since 1991 or diagnosed in our centre. Among them eight typical samples of primary PEACs and usual PACs were detected by targeted exome sequencing. RESULTS: The combination of CK7+/CDX2+ acquires high sensitivity (71.3%) and specificity (82%) in differential diagnosis of PEACs from CRAC. The primary PEACs harbor a high incidence of KRAS mutation but almost absent of EGFR mutation. Moreover, compared with usual PACs, the primary PEACs have higher nonsynonymous tumor mutation burden and more frequent MMR mutation. CONCLUSIONS: The combination of CK7+/CDX2+ immunostaining and the distinctive genetic signatures, including low incidence of sensitivity genes mutations and high tumor mutation burden, is an important supplementary to the clinical differential diagnosis of primary PEACs. Our findings thus have significant implications for development of individualized treatment strategy in these patients. PMID- 29587864 TI - Outcome Measures in Rheumatology - Interventions for medication Adherence (OMERACT-Adherence) Core Domain Set for Trials of Interventions for Medication Adherence in Rheumatology: 5 Phase Study Protocol. AB - BACKGROUND: Over the last 20 years, there have been marked improvements in the availability of effective medications for rheumatic conditions such as gout, osteoporosis and rheumatoid arthritis (RA), which have led to a reduction in disease flares and the risk of re-fracture in osteoporosis, and the slowing of disease progression in RA. However, medication adherence remains suboptimal, as treatment regimens can be complex and difficult to continue long term. Many trials have been conducted to improve adherence to medication. Core domains, which are the outcomes of most relevance to patients and clinicians, are a pivotal component of any trial. These core domains should be measured consistently, so that all relevant trials can be combined in systematic reviews and meta-analyses to reach conclusions that are more valid. Failure to do this severely limits the potential for trial-based evidence to inform decisions on how to support medication adherence. The Outcome Measures in Rheumatology (OMERACT) - Interventions for Medication Adherence study by the OMERACT-Adherence Group aims to develop a core domain set for interventions that aim to support medication adherence in rheumatology. METHODS/DESIGN: This OMERACT-Adherence study has five phases: (1) a systematic review to identify outcome domains that have been reported in interventions focused on supporting medication adherence in rheumatology; (2) semi-structured stakeholder interviews with patients and caregivers to determine their views on the core domains; (3) focus groups using the nominal group technique with patients and caregivers to identify and rank domains that are relevant to them, including the reasons for their choices; (4) an international three-round modified Delphi survey involving patients with diverse rheumatic conditions, caregivers, health professionals, researchers and other stakeholders to develop a preliminary core domain set; and (5) a stakeholder workshop with OMERACT members to review, vote on and reach a consensus on the core domain set for interventions to support medication adherence in rheumatology. DISCUSSION: Establishing a core domain set to be reported in all intervention studies undertaken to support patients with medication adherence will enhance the relevance and the impact of these results and improve the lives of people with rheumatic conditions. PMID- 29587866 TI - miR-148b-3p inhibits gastric cancer metastasis by inhibiting the Dock6/Rac1/Cdc42 axis. AB - BACKGROUND: Our previous work showed that some Rho GTPases, including Rho, Rac1 and Cdc42, play critical roles in gastric cancer (GC); however, how they are regulated in GC remains largely unknown. In this study, we aimed to investigate the roles and molecular mechanisms of Dock6, an atypical Rho guanine nucleotide exchange factor (GEF), in GC metastasis. METHODS: The expression levels of Dock6 and miR-148b-3p in GC tissues and paired nontumor tissues were determined by immunohistochemistry (IHC) and in situ hybridization (ISH), respectively. The correlation between Dock6/miR-148b-3p expression and the overall survival of GC patients was calculated by the Kaplan-Meier method and log-rank test. The roles of Dock6 and miR-148b-3p in GC were investigated by in vitro and in vivo functional studies. Rac1 and Cdc42 activation was investigated by GST pull-down assays. The inhibition of Dock6 transcription by miR-148b-3p was determined by luciferase reporter assays. RESULTS: A significant increase in Dock6 expression was found in GC tissues compared with nontumor tissues, and its positive expression was associated with lymph node metastasis and a higher TNM stage. Patients with positive Dock6 expression exhibited shorter overall survival periods than patients with negative Dock6 expression. Dock6 promoted GC migration and invasion by increasing the activation of Rac1 and Cdc42. miR-148b-3p expression was negatively correlated with Dock6 expression in GC, and it decreased the motility of GC cells by inhibiting the Dock6/Rac1/Cdc42 axis. CONCLUSIONS: Dock6 was over-expressed in GC tissues, and its positive expression was associated with GC metastasis and indicated poor prognosis of GC patients. Targeting of Dock6 by miR-148b-3p could activate Rac1 and Cdc42, directly affecting the motility of GC cells. Targeting the Dock6-Rac1/Cdc42 axis could serve as a new therapeutic strategy for GC treatment. PMID- 29587867 TI - Group consensus peer review in radiation oncology: commitment to quality. AB - BACKGROUND: Peer review, especially prospective peer review, has been supported by professional organizations as an important element in optimal Radiation Oncology practice based on its demonstration of efficacy at detecting and preventing errors prior to patient treatment. Implementation of peer review is not without barriers, but solutions do exist to mitigate or eliminate some of those barriers. METHODS: Peer review practice at our institution involves three key elements: new patient conference, treatment planning conference, and chart rounds. The treatment planning conference is an adaptation of the group consensus peer review model from radiology which utilizes a group of peers reviewing each treatment plan prior to implementation. The peer group in radiation oncology includes Radiation Oncologists, Physician Residents, Medical Physicists, Dosimetrists, and Therapists. Thus, technical and clinical aspects of each plan are evaluated simultaneously. RESULTS: Though peer review is held in high regard in Radiation Oncology, many barriers commonly exist preventing optimal implementation such as time intensiveness, repetition, and distraction from clinic time with patients. Through the use of automated review tools and commitment by individuals and administration in regards to staffing, scheduling, and responsibilities, these barriers have been mitigated to implement this Group Consensus Peer Review model into a Radiation Oncology Clinic. CONCLUSION: A Group Consensus Peer Review model has been implemented with strategies to address common barriers to effective and efficient peer review. PMID- 29587868 TI - Problems recruiting and retaining postnatal women to a pilot randomised controlled trial of a web-delivered weight loss intervention. AB - OBJECTIVE: This paper highlights recruitment and retention problems identified during a pilot randomised controlled trial and process evaluation. The pilot trial aimed to evaluate the feasibility and acceptability of a web-delivered weight loss intervention for postnatal women and associated trial protocol. RESULTS: General practice database searches revealed low rates of eligible postnatal women per practice. 16 (10%) of the 168 identified women were recruited and randomised, seven to the intervention and nine to the control. 57% (4/7) of the intervention women completed 3 month follow-up measurements in comparison to 56% (5/9) in the control group. By 12 months, retention in the intervention group was 43% (3/7), with 2/7 women active on the website, in comparison to 44% (4/9) of the control group. Interview findings revealed the web as an acceptable method for delivery of the intervention, with the suggestion of an addition of a mobile application. Alternative recruitment strategies, using health visitor appointments, midwifery departments or mother and baby/toddler groups, should be explored. Greater involvement of potential users should enable better recruitment methods to be developed. Trial registration ISRCTN: ISRCTN48086713, Registered 26 October 2012. PMID- 29587869 TI - Perspectives of health professionals on the best care settings for pediatric trauma casualties: a qualitative study. AB - BACKGROUND: Critically-injured children are frequently treated by providers who lack specialty pediatric training in facilities that have not been modified for the care of children. We set out to understand the attitudes and perspectives of policy makers, and senior nursing and medical managers in the Israeli healthcare system, concerning the provision of medical care to pediatric trauma casualties in emergency departments. METHODS: We conducted semi-structured interviews with 17 health professionals from medical centers across Israel and the Ministry of Health. The interviews were analyzed by qualitative methods. RESULTS: There was lack of clarity and uniformity concerning the definition of a pediatric trauma casualty. All of the participants attributed extreme importance to the professional level of the care team manager, and most suggested that this should be a pediatric emergency medicine specialist. They emphasized the importance of around-the-clock availability of pediatric medical teams to care for young trauma casualties, and the crucial need for caregivers to be equipped with a wide variety of professional skills for the adequate treatment of a broad spectrum of injuries. All participants described significant variability in pediatric-care training and experience among physicians and nurses working in emergency departments. Most participants believe that pediatric trauma casualties should be treated in designated pediatric emergency departments, in a limited number of medical centers across the country. CONCLUSIONS: Our findings indicate that specialized pediatric EDs would constitute the best location for intake of children with major traumatic injuries. Pediatric emergency medicine specialists should manage trauma cases using pediatric surgeons as ad-hoc consultants. The term 'pediatric patient' should be defined to allow trauma patients to be referred to the most appropriate ED. Teams working at these EDs should undergo specialized pediatric emergency medicine training. Finally, to regulate the key aspects of trauma care, clear statutory guidelines should be formulated at national and local levels. PMID- 29587870 TI - Supraspinatus tendon repair using anchors: a biomechanical evaluation in the rabbit. AB - BACKGROUND: Arthroscopic rotator cuff repairs are mostly secured with suture anchors and often supplemented by footprint decortication. The objectives of this study were to characterize the strength of bone-tendon healing following anchor repair and assess the effect of channeling the supraspinatus (SSP) humeral footprint 1 week ahead of reattachment surgery. METHODS: One hundred twelve rabbits underwent unilateral detachment of one SSP tendon and were randomly assigned to two groups: channeling the footprint at time of detachment and no channeling. One week later, reattachment was performed using an anchor. The repaired and contralateral shoulders were harvested at 0, 1, 2, or 4 weeks after repair and mechanically tested to failure. Outcome measures included load at failure, stiffness, and site of failure. RESULTS: Anchor fixation had a mean load at failure of 81 +/- 32 N and a stiffness of 27 +/- 9 N/mm immediately after repair compared to 166 +/- 47 N and 66 +/- 13 N/mm in the contralateral (both p < 0.05). Mechanical recovery of the reattached SSP tendon was achieved after 4 weeks (221 +/- 73 N, 206 +/- 59 N, and 198 +/- 49 N in the channeling, no channeling, and contralateral groups, respectively, p > 0.05). The dominant site of failure shifted from the footprint at 0/1 week to bone avulsion/mid-substance tear at 4 weeks (p < 0.05). There were no differences in outcomes between the channeling and no channeling groups. CONCLUSIONS: This study is the first of its kind to provide quantitative data on the mechanical properties of the enthesis following anchor repair in a rabbit model. Anchor repair led to rapid and complete restoration of SSP mechanical properties. Further evidence is needed before recommending channeling ahead of repair surgery. PMID- 29587871 TI - Amyloid-beta modulates microglial responses by binding to the triggering receptor expressed on myeloid cells 2 (TREM2). AB - BACKGROUND: TREM2 is an innate immune receptor specifically expressed in microglia. Coding variations in TREM2 have been reported to increase the risk for Alzheimer's disease (AD) and other neurodegenerative diseases. While multiple studies support a role for TREM2 in microglial recruitment to amyloid plaques, the chemoattractant factor modulating TREM2-dependent microglial responses has not been defined. METHODS: Potential binding of oligomeric amyloid-beta 1-42 (oAbeta1-42) to TREM2 was tested by complementary approaches including solid phase binding, surface plasmon resonance and immunoprecipitation assays. The ability of oAbeta1-42 to activate TREM2 signaling pathways was examined by analyzing the phosphorylation of Syk and Akt in primary microglia as well as TREM2-mediated signaling in a reporter cell system. Lastly, the functional outcome of oAbeta1-42-TREM2 interaction was tested by examining impacts on microglial migration in vitro and clustering around oAbeta1-42-bearing brain areas in vivo. RESULTS: We found that oAbeta1-42 bound to TREM2 with high affinity and activated TREM2-dependent signaling pathway. Neither monomeric nor scrambled Abeta bound to TREM2 supporting a specific interaction between oAbeta and TREM2. The disease-associated mutations of TREM2 reduced its binding affinity to oAbeta1-42. Furthermore, we identified several positively charged amino acids within residues 31-91 of TREM2 that were crucial for its interaction with oAbeta1 42. Importantly, oAbeta1-42 promoted microglial migration in vitro and clustering in vivo in a TREM2-dependent manner. CONCLUSIONS: Our data establish a critical link between oAbeta1-42, a major pathological component of AD, and TREM2, a strong genetic risk factor for AD expressed in microglia, and suggest that such interaction contributes to the pathogenic events in AD by modulating microglial responses. PMID- 29587872 TI - Sequencing the exons of human glucocorticoid receptor (NR3C1) gene in Han Chinese with high-altitude pulmonary edema. AB - BACKGROUND: High-altitude pulmonary edema (HAPE) is a serious acute mountain sickness that mainly occurs in non-acclimatized individuals after rapid ascent to high altitude. The precise etiology of HAPE remains unclear. This study aimed to investigate whether NR3C1 gene polymorphism is associated with the susceptibility to HAPE. METHODS: The exons of NR3C1 gene were sequenced by a ABI 3730 DNA analyzer in 133 HAPE patients and matched 135 healthy Han Chinese controls from the Yushu area in Qinghai (the altitude greater than 3500 m). RESULTS: DNA sequencing showed the heterozygous substitutions at codon 588 (rs6194) in exon 6 and 766 (rs6196) in exon 9 of NR3C1 gene. The genotypic distributions and allelic frequencies of NR3C1 SNP rs6194 showed significant differences in two groups (P < 0.05). The frequencies of the C allele were significantly higher in the HAPE group than in the control group (P < 0.05) with an odds ratio of 3.009 (95% CI = 1.250-7.244). There were no differences in genotypic and allelic frequencies in rs6196 polymorphism between the two groups. CONCLUSIONS: NR3C1 gene rs6194 polymorphism is correlated with HAPE susceptibility. CC genotype and C allele of rs6194 polymorphism might increase the risk of HAPE in Han Chinese. PMID- 29587874 TI - The effects of different forms of daily exercise on metabolic function following short-term overfeeding and reduced physical activity in healthy young men: study protocol for a randomised controlled trial. AB - BACKGROUND: Short-term overfeeding combined with reduced physical activity impairs metabolic function and alters the expression of key genes within adipose tissue. We have shown that daily vigorous-intensity running can prevent these changes independent of any net effect on energy imbalance. However, which type, intensity and/or duration of exercise best achieves these benefits remains to be ascertained. METHODS/DESIGN: Forty-eight healthy young men will be recruited and randomly allocated to one of four experimental conditions for 1 week: (1) to ingest 50% more energy than normal by over-consuming their habitual diet whilst simultaneously restricting their physical activity below 4000 steps day-1 (i.e. energy surplus; SUR group); (2) the same regimen but with a daily 45-min bout of vigorous-intensity arm crank ergometry at 70% of maximum oxygen uptake (SUR + ARM group); (3) the same regimen but with a daily 45-min bout of moderate-intensity treadmill walking at 50% of maximum oxygen uptake (SUR + MOD group); (4) the same regimen but with the addition of intermittent short bouts of walking during waking hours (SUR + BREAKS group). Critically, all exercise groups will receive additional dietary energy intake to account for the energy expended by exercise, thus maintaining a matched energy surplus. At baseline and follow-up, fasted blood samples, abdominal subcutaneous adipose tissue and skeletal muscle biopsies will be obtained and oral glucose tolerance tests conducted. DISCUSSION: This study will establish the impact of different forms of daily exercise on metabolic function at the whole-body level as well as within adipose tissue and skeletal muscle in the context of a standardised energy surplus.

AB - BACKGROUND: Phlebotomus papatasi sand flies are major vectors of Leishmania major and phlebovirus infection in North Africa and across the Middle East to the Indian subcontinent. Population genetics is a valuable tool in understanding the level of genetic variability present in vector populations, vector competence, and the development of novel control strategies. This study investigated the genetic differentiation between P. papatasi populations in Egypt and Jordan that inhabit distinct ecotopes and compared this structure to P. papatasi populations from a broader geographical range. METHODS: A 461 base pair (bp) fragment from the mtDNA cytochrome b (cyt b) gene was PCR amplified and sequenced from 116 individual female sand flies from Aswan and North Sinai, Egypt, as well as Swaimeh and Malka, Jordan. Haplotypes were identified and used to generate a median-joining network, F ST values and isolation-by-distance were also evaluated. Additional sand fly individuals from Afghanistan, Iran, Israel, Jordan, Libya, Tunisia and Turkey were included as well as previously published haplotypes to provide a geographically broad genetic variation analysis. RESULTS: Thirteen haplotypes displaying nine variant sites were identified from P. papatasi collected in Egypt and Jordan. No private haplotypes were identified from samples in North Sinai, Egypt, two were observed in Aswan, Egypt, four from Swaimeh, Jordan and two in Malka, Jordan. The Jordan populations clustered separately from the Egypt populations and produced more private haplotypes than those from Egypt. Pairwise F ST values fall in the range 0.024-0.648. CONCLUSION: The clustering patterns and pairwise F ST values indicate a strong differentiation between Egyptian and Jordanian populations, although this population structure is not due to isolation-by-distance. Other factors, such as environmental influences and the genetic variability in the circulating Le. major parasites, could possibly contribute to this heterogeneity. The present study aligns with previous reports in that pockets of genetic differentiation exists between populations of this widely dispersed species but, overall, the species remains relatively homogeneous. PMID- 29587875 TI - Evaluation of a novel device for the management of high blood pressure and shock in pregnancy in low-resource settings: study protocol for a stepped-wedge cluster randomised controlled trial (CRADLE-3 trial). AB - BACKGROUND: Obstetric haemorrhage, sepsis and pregnancy hypertension account for more than 50% of maternal deaths worldwide. Early detection and effective management of these conditions relies on vital signs. The Microlife(r) CRADLE Vital Sign Alert (VSA) is an easy-to-use, accurate device that measures blood pressure and pulse. It incorporates a traffic-light early warning system that alerts all levels of healthcare provider to the need for escalation of care in women with obstetric haemorrhage, sepsis or pregnancy hypertension, thereby aiding early recognition of haemodynamic instability and preventing maternal mortality and morbidity. The aim of the trial was to determine whether implementation of the CRADLE intervention (the Microlife(r) CRADLE VSA device and CRADLE training package) into routine maternity care in place of existing equipment will reduce a composite outcome of maternal mortality and morbidity in low- and middle-income country populations. METHODS: The CRADLE-3 trial was a stepped-wedge cluster-randomised controlled trial of the CRADLE intervention compared to routine maternity care. Each cluster crossed from routine maternity care to the intervention at 2-monthly intervals over the course of 20 months (April 2016 to November 2017). All women identified as pregnant or within 6 weeks postpartum, presenting for maternity care in cluster catchment areas were eligible to participate. Primary outcome data (composite of maternal death, eclampsia and emergency hysterectomy per 10,000 deliveries) were collected at 10 clusters (Gokak, Belgaum, India; Harare, Zimbabwe; Ndola, Zambia; Lusaka, Zambia; Free Town, Sierra Leone; Mbale, Uganda; Kampala, Uganda; Cap Haitien, Haiti; South West, Malawi; Addis Ababa, Ethiopia). This trial was informed by the Medical Research Council guidance for complex interventions. A process evaluation was undertaken to evaluate implementation in each site and a cost-effectiveness evaluation will be undertaken. DISCUSSION: All aspects of this protocol have been evaluated in a feasibility study, with subsequent optimisation of the intervention. This trial will demonstrate the potential impact of the CRADLE intervention on reducing maternal mortality and morbidity in low-resource settings. It is anticipated that the relatively low cost of the intervention and ease of integration into existing health systems will be of significant interest to local, national and international health policy-makers.

PMID- 29587876 TI - Native entomopathogenic Metarhizium spp. from Burkina Faso and their virulence against the malaria vector Anopheles coluzzii and non-target insects. AB - BACKGROUND: Genetically enhanced Metarhizium pingshaense are being developed for malaria vector control in Burkina Faso. However, not much is known about the local prevalence and pathogenicity of this fungus, so we prospected mosquitoes and plant roots (a common habitat for Metarhizium spp.) for entomopathogenic fungi. RESULTS: Our investigations showed that Metarhizium spp. represented between 29-74% of fungi isolated from plant root rhizospheres in diverse collection sites. At low spore dosages (1 * 106 conidia/ml), two mosquito-derived M. pingshaense isolates (Met_S26 and Met_S10) showed greater virulence against Anopheles coluzzii (LT80 of ~7 days) than isolates tested in previous studies (LT80 of ~10 days). In addition, the local isolates did not cause disease in non target insects (honeybees and cockroaches). CONCLUSIONS: Our work provides promising findings for isolating local Metarhizium strains for application in mosquito biological control and for future transgenic biocontrol strategies in Burkina Faso. PMID- 29587877 TI - Occurrence and distribution of Giardia species in wild rodents in Germany. AB - BACKGROUND: Giardiasis is an important gastrointestinal parasitic disease in humans and other mammals caused by the protozoan Giardia duodenalis. This species complex is represented by genetically distinct groups (assemblages A-H) with varying zoonotic potential and host preferences. Wild rodents can harbor potentially zoonotic assemblages A and B, and the rodent-specific assemblage G. Other Giardia spp. found in these animals are Giardia muris and Giardia microti. For the latter, only limited information on genetic typing is available. It has been speculated that wild rodents might represent an important reservoir for parasites causing human giardiasis. The aim of this study was to investigate the occurrence and distribution of Giardia spp. and assemblage types in wild rodents from different study sites in Germany. RESULTS: Screening of 577 wild rodents of the genera Apodemus, Microtus and Myodes, sampled at eleven study sites in Germany, revealed a high overall Giardia prevalence. Giardia species determination at the SSU rDNA gene locus revealed that Apodemus mice, depending on species, were predominantly infected with one of two distinct G. muris sequence types. Giardia microti was the predominant parasite species found in voles of the genera Microtus and Myodes. Only a few animals were positive for potentially zoonotic G. duodenalis. Subtyping at the beta-giardin (bg) and glutamine dehydrogenase (gdh) genes strongly supported the existence of different phylogenetic subgroups of G. microti that are preferentially harbored by distinct host species. CONCLUSIONS: The present study highlights the preference of G. muris for Apodemus, and G. microti for Microtus and Myodes hosts and argues for a very low prevalence of zoonotic G. duodenalis assemblages in wild rodents in Germany. It also provides evidence that G. muris and G. microti subdivide into several phylogenetically distinguishable subgroups, each of which appears to be preferentially harbored by species of a particular rodent host genus. Finally, the study expands the database of sequences relevant for sequence typing of G. muris and G. microti isolates which will greatly help future analyses of these parasites' population structure. PMID- 29587878 TI - Is Afamin a novel biomarker for gestational diabetes mellitus? A pilot study. AB - BACKGROUND: In search of potential early biomarkers for timely prediction of gestational diabetes mellitus (GDM), we focused on afamin, a vitamin E-binding protein in human plasma.. Afamin plays a role in anti-apoptotic cellular processes related to oxidative stress and is associated with insulin resistance and other features of metabolic syndrome. During uncomplicated pregnancy its serum concentrations increase linearly. The aim of this study was to investigate the suitability of afamin as early marker for predicting GDM. METHODS: In a first trimester cohort from a prospective observational study of adverse pregnancy outcomes we secondarily analyzed afamin concentrations in 59 patients diagnosed with GDM and 51 controls. Additionally, afamin concentrations were cross sectionally examined in a mid-trimester cohort of 105 women and compared with results from a simultaneously performed oral glucose tolerance test (OGTT). Subgroup analysis comparing patients treated with either insulin (iGDM) or dietary intervention (dGDM) was performed in both cohorts. Patients were recruited at the University Hospital Essen, Germany, between 2003 and 2016. RESULTS: Results were adjusted for body-mass-index (BMI) and gestational age. First and mid-trimester cohorts yielded significantly elevated afamin concentrations in patients with pathological OGTT compared to patients without GDM (first trimester cohort: mean, 113.4 mg/l; 95% CI, 106.4-120.5 mg/l and 87.2 mg/l; 95% CI, 79.7-94.7 mg/l; mid-trimester cohort: mean, 182.9 mg/l; 95% CI, 169.6-196.2 mg/l and 157.3 mg/l; 95% CI, 149.1-165.4 mg/l, respectively). In the first-trimester cohort, patients developing iGDM later in pregnancy presented with significantly higher afamin concentrations compared to patients developing dGDM and compared to patients without GDM. In the mid-trimester cohort, mean concentrations of afamin differed significantly between patients with dGDM compared to controls and between patients with iGDM and controls. Patients with iGDM showed only slightly higher afamin levels compared to patients with dGDM. CONCLUSION: Afamin may serve as a new early biomarker for pathological glucose metabolism during pregnancy. Further research is needed to determine afamin's concentrations during pregnancy, its predictive value for early detection of pregnancies at high risk to develop GDM and its diagnostic role during the second trimester. PMID- 29587879 TI - Rituximab impedes natural killer cell function in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis patients: A pilot in vitro investigation. AB - BACKGROUND: A recent in vitro pilot investigation reported Rituximab significantly reduced natural killer (NK) cell cytotoxicity in healthy donors. Chronic fatigue syndrome/Myalgic encephalomyelitis (CFS/ME) is a debilitating disorder of unknown etiology. A consistent finding is a significant reduction in NK cell cytotoxicity. Rituximab has been reported having questionable potential therapeutic benefits for the treatment of CFS/ME, however, the potential effects of Rituximab on NK cell cytotoxicity in CFS/ME patients are yet to be determined. METHODS: A total of eight CFS/ME patients (48.63 +/- 15.69 years) and nine non fatigued controls (NFC) (37.56 +/- 11.06 years) were included using the Fukuda case definition. Apoptotic function, lytic proteins and degranulation markers were measured on isolated NK cells using flow cytometry following overnight incubation with Rituximab at 10 MUg/ml and 100 MUg/ml. RESULTS: There was a significant reduction in NK cell lysis between CFS/ME patients and NFC following incubation with Rituximab at 100 MUg/ml at 12.5:1 and 6.25:1 effecter-target (E:T) ratios (p < 0.05). However, there was no significant difference for NFC following incubation with Rituximab at 10 MUg/ml and 100 MUg/ml. There was no significant difference between CFS/ME patients and NFC for granzyme A and granzyme B prior to incubation with Rituximab and following overnight incubation with Rituximab at 10 MUg/ml. There was a significant decrease in granzyme B in CFS/ME patients compared to NFC with 100 MUg/ml of Rituximab prior to K562 cells stimulation (p < 0.05). There was a significant increase in CD107a (p < 0.05) and CD107b expression (p < 0.01) in NFC after stimulation with K562 cells prior to incubation with Rituximab. There was a significant increase in CD107b expression between CFS/ME patients and NFC prior to incubation with Rituximab and without stimulation of K562 cells (p < 0.01). Importantly, there was a significant increase in CD107b following overnight incubation with 100 MUg/ml of Rituximab in NFC prior to K562 cells stimulation (p < 0.01). CONCLUSION: This study reports significant decreases in NK cell lysis and a significant increase in NK cell degranulation following Rituximab incubation in vitro in CFS/ME patients, suggesting Rituximab may be toxic for NK cells. Caution should be observed in clinical trials until further investigations in a safe and controlled in vitro setting are completed. PMID- 29587880 TI - Hybridization capture reveals microbial diversity missed using current profiling methods. AB - BACKGROUND: Microorganisms comprise the majority of living organisms on our planet. For many years, exploration of the composition of microbial communities has been performed through the PCR-based study of the small subunit rRNA gene due to its high conservation across the domains of life. The application of this method has resulted in the discovery of many unexpected evolutionary lineages. However, amplicon sequencing is subject to numerous biases, with some taxa being missed, and is limited by the read length of second-generation sequencing platforms, which drastically reduces the phylogenetic resolution. RESULTS: Here, we describe a hybridization capture strategy that allows the enrichment of 16S rRNA genes from metagenomic samples and enables an exhaustive identification and a complete reconstruction of the biomarker. Applying this approach to a microbial mock community and a soil sample, we demonstrated that hybridization capture is able to reveal greater microbial diversity than 16S rDNA amplicon sequencing and shotgun sequencing. The reconstruction of full-length 16S rRNA genes facilitated the improvement of phylogenetic resolution and the discovery of novel prokaryotic taxa. CONCLUSIONS: Our results demonstrate that hybridization capture can lead to major breakthroughs in our understanding of microbial diversity, overcoming the limitations of conventional 16S rRNA gene studies. If applied to a broad range of environmental samples, this innovative approach could reveal the undescribed diversity of the still underexplored microbial communities and could provide a better understanding of ecosystem function. PMID- 29587881 TI - TEDDI: radiotherapy delivery in deep inspiration for pediatric patients - a NOPHO feasibility study. AB - BACKGROUND: Radiotherapy (RT) delivered in deep inspiration breath-hold (DIBH) is a simple technique, in which changes in patient anatomy can significantly reduce the irradiation of the organs at risk (OARs) surrounding the treatment target. DIBH is routinely used in the treatment of some adult patients to diminish the risk of late effects; however, no formalized studies have addressed the potential benefit of DIBH in children. METHODS/DESIGN: TEDDI is a multicenter, non randomized, feasibility study. The study investigates the dosimetric benefit of RT delivered in DIBH compared to free breathing (FB) in pediatric patients. Also, the study aims to establish the compliance to DIBH and to determine the accuracy and reproducibility in a pediatric setting. Pediatric patients (aged 5-17 years) with a tumor in the mediastinum or upper abdomen with the possible need of RT will be included in the study. Written informed consent is obligatory. Prior to any treatment, patients will undergo a DIBH training session followed by a diagnostic PET/CT- or CT-staging scan in both DIBH and FB. If the patient proceeds to RT, a RT planning CT scan will be performed in both DIBH and FB and two separate treatment plans will be calculated. The superior treatment plan, i.e. equal target coverage and lowest overall dose to the OARs, will be chosen for treatment. Patient comfort will be assessed daily by questionnaires and by adherence to the respiratory management procedure. DISCUSSION: RT in DIBH is expected to diminish irradiation of the OARs surrounding the treatment target and thereby reduce the risk of late effects in childhood cancer survivors.

PMID- 29587882 TI - Comparative effectiveness of malaria prevention measures: a systematic review and network meta-analysis. AB - BACKGROUND: Malaria causes significant morbidity and mortality worldwide. There are several preventive measures that are currently employed, including insecticide-treated nets (ITNs, including long-lasting insecticidal nets and insecticidal-treated bed nets), indoor residual spraying (IRS), prophylactic drugs (PD), and untreated nets (UN). However, it is unclear which measure is the most effective for malaria prevention. We therefore undertook a network meta analysis to compare the efficacy of different preventive measures on incidence of malaria infection. METHODS: A systematic literature review was undertaken across four medical and life sciences databases (PubMed, Cochrane Central, Embase, and Web of Science) from their inception to July 2016 to compare the effectiveness of different preventive measures on malaria incidence. Data from the included studies were analysed for the effectiveness of several measures against no intervention (NI). This was carried out using an automated generalized pairwise modeling (GPM) framework for network meta-analysis to generate mixed treatment effects against a common comparator of no intervention (NI). RESULTS: There were 30 studies that met the inclusion criteria from 1998-2016. The GPM framework led to a final ranking of effectiveness of measures in the following order from best to worst: PD, ITN, IRS and UN, in comparison with NI. However, only ITN (RR: 0.49, 95% CI: 0.32-0.74) showed precision while other methods [PD (RR: 0.24, 95% CI: 0.004-15.43), IRS (RR: 0.55, 95% CI: 0.20-1.56) and UN (RR: 0.73, 95% CI: 0.28-1.90)] demonstrating considerable uncertainty associated with their point estimates. CONCLUSION: Current evidence is strong for the protective effect of ITN interventions in malaria prevention. Even though ITNs were found to be the only preventive measure with statistical support for their effectiveness, the role of other malaria control measures may be important adjuncts in the global drive to eliminate malaria. PMID- 29587886 TI - A definition of free sugars for the UK. AB - Public Health England has set a definition for free sugars in the UK in order to estimate intakes of free sugars in the National Diet and Nutrition Survey. This follows the recommendation from the Scientific Advisory Committee on Nutrition in its 2015 report on Carbohydrates and Health that a definition of free sugars should be adopted. The definition of free sugars includes: all added sugars in any form; all sugars naturally present in fruit and vegetable juices, purees and pastes and similar products in which the structure has been broken down; all sugars in drinks (except for dairy-based drinks); and lactose and galactose added as ingredients. The sugars naturally present in milk and dairy products, fresh and most types of processed fruit and vegetables and in cereal grains, nuts and seeds are excluded from the definition. PMID- 29587884 TI - Effectiveness of psychological interventions to improve quality of life in people with long-term conditions: rapid systematic review of randomised controlled trials. AB - BACKGROUND: Long-term conditions may negatively impact multiple aspects of quality of life including physical functioning and mental wellbeing. The rapid systematic review aimed to examine the effectiveness of psychological interventions to improve quality of life in people with long-term conditions to inform future healthcare provision and research. METHODS: EBSCOhost and OVID were used to search four databases (PsychInfo, PBSC, Medline and Embase). Relevant papers were systematically extracted by one researcher using the predefined inclusion/exclusion criteria based on titles, abstracts, and full texts. Randomized controlled trial psychological interventions conducted between 2006 and February 2016 to directly target and assess people with long-term conditions in order to improve quality of life were included. Interventions without long term condition populations, psychological intervention and/or patient-assessed quality of life were excluded. RESULTS: From 2223 citations identified, 6 satisfied the inclusion/exclusion criteria. All 6 studies significantly improved at least one quality of life outcome immediately post-intervention. Significant quality of life improvements were maintained at 12-months follow-up in one out of two studies for each of the short- (0-3 months), medium- (3-12 months), and long term (>= 12 months) study duration categories. CONCLUSIONS: All 6 psychological intervention studies significantly improved at least one quality of life outcome immediately post-intervention, with three out of six studies maintaining effects up to 12-months post-intervention. Future studies should seek to assess the efficacy of tailored psychological interventions using different formats, durations and facilitators to supplement healthcare provision and practice. PMID- 29587887 TI - Excess free fructose, high-fructose corn syrup and adult asthma: the Framingham Offspring Cohort. AB - There is growing evidence that intakes of high-fructose corn syrup (HFCS), HFCS sweetened soda, fruit drinks and apple juice - a high-fructose 100 % juice - are associated with asthma, possibly because of the high fructose:glucose ratios and underlying fructose malabsorption, which may contribute to enteral formation of pro-inflammatory advanced glycation end products, which bind receptors that are mediators of asthma. Cox proportional hazards models were used to assess associations between intakes of these beverages and asthma risk, with data from the Framingham Offspring Cohort. Diet soda and orange juice - a 100 % juice with a 1:1 fructose:glucose ratio - were included for comparison. Increasing intake of any combination of HFCS-sweetened soda, fruit drinks and apple juice was significantly associated with progressively higher asthma risk, plateauing at 5-7 times/week v. never/seldom, independent of potential confounders (hazard ratio 1.91, P<0.001). About once a day consumers of HFCS-sweetened soda had a 49 % higher risk (P<0.011), moderate apple juice consumers (2-4 times/week) had a 61 % higher risk (P<0.007) and moderate fruit drink consumers had a 58 % higher risk (P<0.009), as compared with never/seldom consumers. There were no associations with diet soda/orange juice. These associations are possibly because of the high fructose:glucose ratios, and fructose malabsorption. Recommendations to reduce consumption may be inadequate to address asthma risk, as associations are evident even with moderate intake of these beverages, including apple juice - a 100 % juice. The juice reductions in the US Special Supplemental Nutrition Program for Women, Infants, and Children in 2009, and the plateauing/decreasing asthma prevalence (2010-2013), particularly among non-Hispanic black children, may be related. Further research regarding the consequences of fructose malabsorption is needed. PMID- 29587888 TI - Depression and hopelessness as risk factors for suicide ideation, attempts and death: meta-analysis of longitudinal studies. AB - BACKGROUND: Many studies have documented robust relationships between depression and hopelessness and subsequent suicidal thoughts and behaviours; however, much weaker and non-significant effects have also been reported. These inconsistencies raise questions about whether and to what degree these factors confer risk for suicidal thoughts and behaviours.AimsThis study aimed to evaluate the magnitude and clinical utility of depression and hopelessness as risk factors for suicide ideation, attempts and death. METHOD: We conducted a meta-analysis of published studies from 1971 to 31 December 2014 that included at least one longitudinal analysis predicting suicide ideation, attempt or death using any depression or hopelessness variable. RESULTS: Overall prediction was weaker than anticipated, with weighted mean odds ratios of 1.96 (1.81-2.13) for ideation, 1.63 (1.55-1.72) for attempt and 1.33 (1.18-1.49) for death. Adjusting for publication bias further reduced estimates. Effects generally persisted regardless of sample severity, sample age or follow-up length. CONCLUSIONS: Several methodological constraints were prominent across studies; addressing these issues would likely be fruitful moving forward.Declaration of interestNone.

PMID- 29587883 TI - Elevated polygenic burden for autism is associated with differential DNA methylation at birth. AB - BACKGROUND: Autism spectrum disorder (ASD) is a severe neurodevelopmental disorder characterized by deficits in social communication and restricted, repetitive behaviors, interests, or activities. The etiology of ASD involves both inherited and environmental risk factors, with epigenetic processes hypothesized as one mechanism by which both genetic and non-genetic variation influence gene regulation and pathogenesis. The aim of this study was to identify DNA methylation biomarkers of ASD detectable at birth. METHODS: We quantified neonatal methylomic variation in 1263 infants-of whom ~ 50% went on to subsequently develop ASD-using DNA isolated from archived blood spots taken shortly after birth. We used matched genotype data from the same individuals to examine the molecular consequences of ASD-associated genetic risk variants, identifying methylomic variation associated with elevated polygenic burden for ASD. In addition, we performed DNA methylation quantitative trait loci (mQTL) mapping to prioritize target genes from ASD GWAS findings. RESULTS: We identified robust epigenetic signatures of gestational age and prenatal tobacco exposure, confirming the utility of DNA methylation data generated from neonatal blood spots. Although we did not identify specific loci showing robust differences in neonatal DNA methylation associated with later ASD, there was a significant association between increased polygenic burden for autism and methylomic variation at specific loci. Each unit of elevated ASD polygenic risk score was associated with a mean increase in DNA methylation of - 0.14% at two CpG sites located proximal to a robust GWAS signal for ASD on chromosome 8. CONCLUSIONS: This study is the largest analysis of DNA methylation in ASD undertaken and the first to integrate genetic and epigenetic variation at birth. We demonstrate the utility of using a polygenic risk score to identify molecular variation associated with disease, and of using mQTL to refine the functional and regulatory variation associated with ASD risk variants.

PMID- 29587891 TI - Morbidity, mortality and long-term sequelae of West Nile virus disease in Quebec. AB - We aimed to describe the clinical characteristics of West Nile patients reported in Quebec in 2012 and 2013 and to document physical, mental and functional status 24 months after symptom onset according to illness severity. The cases were recruited by a public health professional. Data were collected from public health files, medical records and two standardised phone questionnaires: the Short Form 36 and the Instrumental Activities of Daily Living. In all, 92 persons participated in the study (25 had West Nile fever (WNF), 18 had meningitis and 49 had encephalitis). Encephalitis participants were older, had more underlying medical conditions, more neurological symptoms, worse hospital course and higher lethality than meningitis or WNF participants. Nearly half of the surviving hospitalised encephalitis patients required extra support upon discharge. At 24 month follow-up, encephalitis and meningitis patients had a lower score in two domains of the mental component: mental health and social functioning (P = 0.0025 and 0.0297, respectively) compared with the norms based on age- and sex-matched Canadians. Physical status was not affected by West Nile virus (WNV) infection. In addition, 5/36 (15%) of encephalitis, 1/17 (6%) of meningitis and 1/23 (5%) of WNF participants had new functional limitations 24 months after symptom onset. In summary, mental and functional sequelae in encephalitis patients are likely to represent a source of long-term morbidity. Preventive measures should target patients at higher risk of severe illness after WNV infection.

There are concerns regarding unequal treatment towards First Nations people when engaged with health care services. What did this study ask? Whether quantitative differences in care exist between First Nations and non-First Nations patients in the ED. What did this study find? First Nations presenting with abdominal pain were found to have no difference in the time-related care parameters relative to non-First Nations patients. Why does this study matter to clinicians? Future quantitative and qualitative studies will be necessary to further understand the care inequality that has been expressed among First Nations patients. PMID- 29587893 TI - Public Health and Mental Health Implications of Environmentally Induced Forced Migration. AB - ABSTRACTClimate change is increasingly forcing population displacement, better described by the phrase environmentally induced forced migration. Rising global temperatures, rising sea levels, increasing frequency and severity of natural disasters, and progressive depletion of life-sustaining resources are among the drivers that stimulate population mobility. Projections forecast that current trends will rapidly accelerate. This will lead to an estimated 200 million climate migrants by the year 2050 and create dangerous tipping points for public health and security.Among the public health consequences of climate change, environmentally induced forced migration is one of the harshest and most harmful outcomes, always involving a multiplicity of profound resource and social losses and frequently exposing migrants to trauma and violence. Therefore, one particular aspect of forced migration, the effects of population displacement on mental health and psychosocial functioning, deserves dedicated focus. Multiple case examples are provided to elucidate this theme. (Disaster Med Public Health Preparedness. 2018;page 1 of 7). PMID- 29587885 TI - Microbial interactions within the plant holobiont. AB - Since the colonization of land by ancestral plant lineages 450 million years ago, plants and their associated microbes have been interacting with each other, forming an assemblage of species that is often referred to as a "holobiont." Selective pressure acting on holobiont components has likely shaped plant associated microbial communities and selected for host-adapted microorganisms that impact plant fitness. However, the high microbial densities detected on plant tissues, together with the fast generation time of microbes and their more ancient origin compared to their host, suggest that microbe-microbe interactions are also important selective forces sculpting complex microbial assemblages in the phyllosphere, rhizosphere, and plant endosphere compartments. Reductionist approaches conducted under laboratory conditions have been critical to decipher the strategies used by specific microbes to cooperate and compete within or outside plant tissues. Nonetheless, our understanding of these microbial interactions in shaping more complex plant-associated microbial communities, along with their relevance for host health in a more natural context, remains sparse. Using examples obtained from reductionist and community-level approaches, we discuss the fundamental role of microbe-microbe interactions (prokaryotes and micro-eukaryotes) for microbial community structure and plant health. We provide a conceptual framework illustrating that interactions among microbiota members are critical for the establishment and the maintenance of host-microbial homeostasis.

AB - n-3 Highly unsaturated fatty acids (HUFA), are essential components of neuronal membranes and mediate a range of complex bioactive properties including gene expression, myelination, cell-signalling and dopaminergic function. Deficits in n 3 HUFA have been linked to increased risks for addictive disorders, thus we posited that lower fish consumption would be associated with greater risks for perinatal smoking among 9640 mothers enroled in the Avon Longitudinal Study of Parents and Children. We used univariable and multivariable regression models to examine relationships between self-reported prenatal dietary intakes of n-3 HUFA rich foods (fish and shellfish) and maternal smoking; outcomes included cessation and the number of cigarettes smoked per d. Both before and during pregnancy, there was consistent evidence (P<0.001) of protective fish intake-smoking associations; relative to mothers reporting no fish consumption, those who reported some fish consumption (<340 g/week) and high fish consumption (340 g+/week) at 32 weeks of gestation showed lower likelihoods of smoking (adjusted P values <0.001). Respective OR for these relationships were 0.87 (95% CI 0.77, 0.97) and 0.73 (95% CI 0.61, 0.86). Although the prevalence of smoking diminished, from a high of 31.6% (pre-pregnancy) to a low of 18.7% (second trimester), the magnitude of fish intake-smoking associations remained stable following adjustment for confounders. These observations suggest that greater fish or n-3 HUFA consumption should be evaluated as an intervention to reduce or prevent smoking in randomised clinical trials.

AB - SummaryAntibody-mediated encephalitis has been discussed as one possible cause for isolated psychotic syndromes. Mostly based on serum samples, findings have been controversial. We present the results of a retrospective study of 124 clinically diagnosed psychotic patients without documented relevant neurological symptoms. All were tested for different antineuronal antibodies in cerebrospinal fluid (CSF) while 81 received serum testing. Antineuronal antibodies in CSF were negative across the sample. 3.7% showed low positive serum antibodies. Our findings highlight the importance of a deeper discussion about the relevance of low positive serum antibodies without concurrent findings in CSF or clinical signs for autoimmune encephalitis.Declaration of interestNone.

AB - The use of chimeric molecules fusing several antigenic determinants is a promising strategy for the development of low-cost, standardized and reliable kits to determine specific antibodies. In this study, we designed and assessed a novel recombinant chimera that complements the performance of our previously developed chimera, CP1 [FRA and SAPA antigens (Ags)], to diagnose chronic Chagas disease. The new chimeric protein, named CP3, is composed of MAP, TcD and TSSAII/V/VI antigenic determinants. We compared the performance of both chimeric Ags using a panel of 67 Trypanosoma cruzi-reactive sera and 67 non-reactive ones. The sensitivity of CP3 vs CP1 was 100 and 90.2%, and specificity was 92.5 and 100%, respectively. The mixture of CP1 + CP3 achieved 100% of sensitivity and specificity. More importantly, an additional subset of 17 sera from patients with discordant results of conventional serological methods was analysed; the CP1 + CP3 mixture allowed us to accurately classify 14 of them with respect to IIF, the usual technique used in most of the reference centres. These results show an improved performance of the CP1 + CP3 mixture in comparison with enzyme-linked immunosorbent assay and indirect haemagglutination commercial assays.

AB - The purpose of this study was to investigate the antibacterial effect of 71 organic Sicilian honeys of different botanical origins against Staphylococcus aureus [American Type Culture Collection (ATCC) 9144TM] and Pseudomonas aeruginosa (ATCC 27853TM). The antimicrobial activity was determined by means of an agar diffusion assay from the estimation of the diameter of the inhibition zone produced by the honeys. S. aureus was more inhibited than P. aeruginosa (chi square value 11.2698, P value 0.000788). In particular, a statistically significant inhibition growth against S. aureus was exhibited by the polyfloral (chi-square value 6.1714, P value 0.012983) and the eucalyptus honeys (chi-square value 4, P value 0.0455). Results partially suggest Sicilian organic polyfloral and eucalyptus honeys as possible alternatives to antimicrobial agents when S. aureus resistance causes failure of initial conventional antibiotic treatment.

AB - Recently, uniportal video-assisted thoracic surgery (VATS) has developed rapidly and has become the main theme of global surgical development. The specific, standardized and systematic training of this technology has become an important topic. Specific training in the uniportal VATS approach is crucial to ensure safety and radical treatment. Such training approach, including a direct interaction with experienced surgeons in high-volume centers, is crucial and represents an indispensable step. Another form of training that usually occurs after preceptorship is proctorship: an experienced mentor can be invited to a trainee's own center to provide specific on-site tutelage. Videos published online are commonly used as training material. Technology has allowed the use of different models of simulators for training. The most common model is the use of animal wet laboratory training. Other models, however, have been used mostrecently, such as the use of 3D and VR Technology, virtual reality simulators, and completely artificial models of the human thorax with synthetic lung, vessel, airway, and nodal tissues. A short-duration, high-volume, clinical immersion training, and a long term systematic training in high-volume centers are getting more and more attention. According to the evaluation of students' grading, a diversified training mode is adopted and the targeted training in accordance with different students helps to improve the training effect. We have done some work in systematic and standardized training of uniportal VATS in single center. We believe such training is feasible and absolutely necessary.

AB - BACKGROUND: Through the comparative analysis of the acute and chronic pain postoperative between the single port and triple port video-assisted thoracic surgery to seek the better method which can reduce the incidence of acute and chronic pain in patients with lung cancer. METHODS: Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative. RESULTS: Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P<0.05). There was no statistically significant difference between the two groups in operative time, blood loss, postoperative hospitalization time, duration of chest tube, the NRS scores in the 3 d (P>0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (P<0.05). CONCLUSIONS: The single port thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

AB - BACKGROUND: The morbidity of lung cancer has long been the highest in cancer. Stage I, stage II and partly of stage III non-small cell lung cancer (NSCLC) are mainly treated by surgery. Lobectomy and segmentectomy both are common lung resection methods. Video-assisted thoracoscopic surgery (VATS) has been widely used in clinical, and the application of single-portvideo-assisted thoracoscopic surgery (SP VATS) has gradually been recognized and accepted by professors. With increasing degree of eldly in society, eldly patients already have become inceasingly difficulties in the diagnosis and treatment of NSCLC. The aim of this study is to explore and analyze clinical value of SP VATS lobectomy and segmentectomy in elderly patients with NSCLC. METHODS: In this retrospective observational study, the outcomes of 417 consecutive patients who had undergone SP VATS anatomic segmentectomy or lobectomy for NSCLC from May 2014 to December 2016 on department of thoracic surgery in Fujian Medical University Affiliated Union Hospital were examined, including 139 elderly-case (lobectomy vs segmentectomy: 124 vs 15) and 278 nonelderly-case (lobectomy vs segmentectomy: 248 vs 30). The condition of perioperative period and postoperative short-time recovery could be compared with lobectomy and segmentectomy between elderly and nonelderly cases and lobectomy and segmentectomy in elderly cases. RESULTS: The morbidty of preoperative complications was significant difference (P<0.05) in comparing with elderly and non-elderly patients with NSCLC either in SP VATS anatomic segmentectomy orlobectomy, except others is no significant difference (P>0.05). Numbers of dissected lymph nodes and mediastinal nodal stations of SP VATS lobectomy in elderly patients with NSCLC were more than segmentectomy (P<0.05), which were (7.61+/-0.21) vs (20.39+/-0.97) and (5.60+/-0.35) vs (15.40+/-2.64). But there was not significant difference between two elderly groups of SP VATS lobectomy and anatomic segmentectomy in age, morbidty of preoperative complications, average operation time and intraoperative blood loss (P>0.05). Postoperative drainage volume [(1,150.15+/-140.02) mL vs (853.53+/ 177.04) mL] and duration [(7.00+/-1.31) d vs (5.00+/-0.74) d], duration of postoperative hospital stay [(3.18+/-1.32) d vs (5.04+/-1.30) d], costs [(70.06+/ 5.23) thousands yuan vs (61.20+/-5.22) thousands yuan ] or postoperative complications (5.97% vs 20.00%)(P>0.05). Notwithstanding, group of SP VATS anatomic segmentectomy found more postoperative atrialfibrillation and the vein thrombosis of lower limbs (P<0.05). CONCLUSIONS: Elderly patients having more basic diseases and taking increasely risk of postoperative complications. SP VATS anatomic segmentectomy andlobectomy do not increase the risk of elderly patients with surgery. SP VATS segmentectomy is as safe and effective as SP VATS lobectomy in elderly patients, who fit to undergo SP VATS segmentectomy seem to get as same short-time effect as SP VATS lobectomy.

AB - BACKGROUND: Surgery was not standard-of-care of patients with advanced lung cancer. However, a serial of retrospective studies demonstrated that thoracic dissemination (M1a) patients could benefit from contraindicated surgery. After non-standard treatment, how should these patients choose following treatment approaches? Herein, we conducted this retrospective study to explore subsequent optimal treatment approaches. METHODS: Different therapeutic approaches were evaluated by comparing progression-free survival (PFS), overall survival (OS), time to treatment interval (TTI) using the Kaplan-Meier method and Log-rank test. A Cox proportional hazards regression model was used for multivariate analysis. RESULTS: 141 eligible were enrolled. The median PFS of chemotherapy group, targeted therapy group and observation group were 14.7, 41.0 and 31.0 months, respectively (95%CI: 19.01-26.01; P<0.001). There was no significantly statistically difference between median PFS of targeted group and observation group (P=0.006). The median OS were 39.0, 42.6 and 38.1 months (95%CI: 32.47 45.33; P=0.478). The median PFS and OS of TTI<3 months and TTI >=3 months were 15.2 months versus 31.0 months (95%CI: 19.01-26.06; P<0.001) and 41.7 months versus 38.7 months (95%CI: 32.47-45.33; P=0.714). Multivariate analyses revealed gender (P=0.027), lymph node status (P=0.036) and initial therapy (P<0.001) were independent prognostic factors for PFS. CONCLUSIONS: Observation did not shorten survival of thoracic dissemination patients with lung adenocarcinoma or squamous carcinoma, therefore, it could be an favorable option. But prospective randomized controlled study was needed to confirm its validity.

AB - BACKGROUND: A retrospective review of the surgical treatment of refractory chest tumors involving the heart or large vessels with cardiopulmonary bypass (CPB). METHODS: To summarize 11 cases of chest tumor patients who had undergone cardiopulmonary bypass surgery from January 2008 to May 2017 in our hospital, and analyze the general condition, clinical characteristics, treatment methods, postoperative hospitalization time, complications and follow-up results of all patients. RESULTS: All 11 patients were operated with cardiopulmonary bypass. Total resection of tumors in 8 cases and most of the excision in 3 cases. 1 case of left atrial metastatic leiomyosarcoma were excised in the left atrium, and then the right lung resection was performed. 1 case of left lung central lung cancer resection through the median sternum incision. 2 cases underwent pulmonary artery repair at the same time, 3 cases underwent partial pericardiectomy and 3 cases underwent pulmonary wedge resection at the same time. All the patients were effectively relieved after the operation. No death rate in hospital and 30 days after operation. 3 cases of postoperative pulmonary infection were recovered after the treatment of antibiotics. 1 case of lymphoma relapsed 6 months after surgery and died one year later. 1 case of pericardial fibrosarcoma had local recurrence and extensive metastasis at 13 months after operation, and died after 15 months. 1 case of pulmonary leiomyosarcoma were found to have local recurrence 15 months after the operation and were relieved after chemotherapy. The remaining 8 patients survived, and no obvious recurrence and distant metastasis were found in the computed tomography (CT) examination. CONCLUSIONS: The CPB assisted surgical treatment can be performed for patient of refractory chest tumors involving the heart or large vessels. It can improve the surgical resection rate of refractory chest tumors, effectively alleviate the effects on respiratory and circulatory functions, and significantly prolong the survival period of these patients.

PMID- 29587920 TI - [Treatment Experience of Continuous Negative Pressure Drainage in the Acute Anterior Mediastinal Infection of Oropharyngeal Origined]. AB - BACKGROUND: Mediastinal infection is a serious infection of mediastinal connective tissue, with more complications and higher mortality. Application of broad-spectrum antibiotics and nutritional support, early sufficient drainage is the key to successful treatment. In the mode of drainage, this paper discusses the application of continuous negative pressure drainage technique to treat acute anterior mediastinal infection of severe mouth pharynx source, and the good results are summarized and shared. METHODS: In January to December in 2017, a total of 17 cases treated acute mediastinal infection is derived from the throat, has formed a mediastinal abscess, surgery adopts retrosternal counterpart negative pressure drainage way, namely the sternum nest and free sternum xiphoid process under the incision on the first mediastinal clearance, make breakthrough and placed drainage device, suture closed wound, continuous negative pressure drainage, negative pressure using 3 cm-5 cm water column. RESULTS: Among the 17 patients, 14 patients were relieved by continuous negative pressure drainage, and then the drainage tube was removed. In 2 cases, the infection broke into the right thoracic cavity, and the closed drainage caused the negative pressure to disappear, and the negative pressure drainage was replaced by the conventional drainage, and the drainage tube was removed after the drainage tube was clear. One patient had formed a mediastinal abscess incision drainage time later, complicated with septic shock and sepsis, resulting in the death of multiple organ failure. CONCLUSIONS: The traditional treatment of severe acute mediastinal infection is sternal incision and drainage. Continuous negative pressure drainage adequate drainage of mediastinal can relieve patients' pain, effusion, and avoid the dressing out repeatedly. It is an effective method. However, there are limitations in this method, which need to be further optimized. PMID- 29587923 TI - [Application of VSD in 6 Cases of Postoperative Infection?-A Clinical Experience Sharing]. AB - BACKGROUND: Surgical site infection is one of the common postoperative complications of thoracic surgery, and its harm is related to infection degree and location. Light causes local pain, prolonged hospitalization and increased cost. Severe infection can lead to severe infection, even septic shock and life threatening. Therefore, proper treatment of incision infection can help to promote recovery, reduce the burden of disease and lay a good foundation for further treatment. The traditional surgical treatment of wound infection includes thorough drainage, intensive dressing change and antibiotic use. There are many shortcomings such as long treatment process, ineffective treatment effect and so on. The experience of using vacuum sealing drainage (VSD) in 6 cases of postoperative infection patients in our department is summarized in order to improve the traditional treatment of postoperative infection in patients after thoracic surgery. METHODS: The clinical data of patients with postoperative incision infection or fistula after thoracic surgery in our department were reviewed and summarized. 6 patients treated with VSD material for postoperative infection. The process and final clinical results of them were summarized and discussed. RESULTS: In this study, fever and wound exudation disappeared within 6 h-10 h after VSD use, 5 cases of wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well at the cutting edge of the operation, the second stage operation was performed to close the chest and skin. One patient was seriously infected, and the secretion was still more after VSD removal, reposition VSD device next time, the VSD device was removed 7 d later. The wound infection were obviously improved, the secretion disappeared and the granulation tissue grew well, close the chest and skin second stage. In all 6 patients, the symptoms were relieved, the symptoms improved and the surgical incision healed well. In 2 patients with esophageal cancer, the average operation time was 427.5 min, the average hospitalization time was 40 d, the average number of times of dressing change was 8.5, the average total cost during hospitalization was 111,893.47 yuan patients with chronic empyema, the average operation time was 192.5 min. The average hospital stay was 27.75 days, the average number of times of dressing change was 5.5, and the average total expenditure during hospitalization was 48,237.71 yuan. CONCLUSIONS: VSD has a good effect on the treatment of postoperative incision infection patients in thoracic surgery. It can reduce the pain and burden of patients and ensure the quality of life of postoperative infected patients. PMID- 29587924 TI - [VSD - A Good Idea for the Management of Surgical Infection].

The management for pulmonary GGN remains controversial. Both Fleischner society and National Comprehensive Cancer Network (NCCN) panel updated the guideline for the management of GGN in 2017. Compared with previous versions, the indication for surgery or biopsy is stricter, and the recommended follow-up interval is prolonged. In clinical practice, the size of GGN component, the size of consolidation component, dynamic change during follow up and computed tomography (CT) value are the four factors that help surgeons to decide the timing of surgery. There are some misunderstandings for the management of GGN, such as the administration of antibiotics, the use of positron emission tomography-computed tomography (PET-CT), pure GGN adjacent to visceral pleura, and GGN with penetrating vessel. In conclusion, GGN is a kind of slowly growing lesion, which can be followed up safely.?. PMID- 29587930 TI - [Shanghai Pulmonary Hospital Experts Consensus on the Management of Ground-Glass Nodules Suspected as Lung Adenocarcinoma (Version 1)]. AB - Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.?. PMID- 29587933 TI - [What is Enhanced Recovery After Surgery: Humanity or Technology?] AB - The development of surgical techniques and the innovation of surgical instruments promote the changes in surgical methods, which in turn, leads to the reforms of surgical idea. The concept of enhanced recovery after surgery (ERAS) results in the surgery connotation switching from "to treat an illness" to "to save patients". ERAS also causes the change of surgery denotation from "only operation" to "enhance recovery". The concept of ERAS is derived from but not only restricted to the development of surgical techniques. Also, ERAS pays more attention to patients than disease and thinks more about patient safety and recovery than surgical technique. Specifically, ERAS has three advantages: first, ERAS attaches importance to multidisciplinary assessment (patient-oriented) and select appropriate (personalized) treatment and tries to decrease the rate of complication and mortality. Second, ERAS pays attention to preoperative preparation and high-risk prevention performed by multi-disciplinary collaboration in order to prevent complication and save cost for patients. Third, ERAS always focus on optimizing the process of perioperative period and trying to change the working habits of surgeons and the old cooperation mode among doctors, nurses and rehabilitation physicians. To sum up, the goal is to apply the concept of ERAS to all the links of perioperative period and try hard to decrease patients' stress and pain, which finally helps doctors fulfill the ultimate aims of "no pain and no risk".?. PMID- 29587932 TI - [The Clinical and Molecular Characteristics of Adenocarcinoma Presented ?by Multi focal GGO]. AB - Due to emphasis on early screening for lung cancer, the detection rate of multiple ground glass opacities (GGOs) on computed tomography (CT) image increases in recent years, and research on multifocal adenocarcinomas presented by GGOs has been thriving. It is more common in women and non-smokers and has excellent prognosis both in patients with natural history and after surgery. These clinical features suggest that it is likely to be a distinct disease entity. From the perspective of molecular genetics, lesions in the same individual are likely to have distinct clonal features. Therefore, genetic heterogeneity is the most prominent feature of multifocal pulmonary adenocarcinomas with GGOs. The genetic heterogeneity is expected to assist the diagnosis of multifocal pulmonary adenocarcinoma and intrapulmonary metastasis, and also suggests that genetic testing of the GGO lesions is of great therapeutic significance. Some GGO lesions may harvest the similar clonal feature, which provide new evidence for the theory of spread through air spaces (STAS).?.

AB - Minimal invasive surgery with short operation time and enhanced recovery after surgery can truly achieve biological minimal invasiveness. The minimal invasive lung cancer surgery includes several kinds, such as uni-portal video-assisted thoracoscopic surgery (VATS) and multi-portal VATS. Robotic-assisted thoracic surgery (RATS) can be categorized into multi-portal VATS. As a frontier technology of minimal invasive surgical technique, surgical robotic system has been broadly applied in many areas. The average RATS operation time is (91.51+/ 30.80) min among our team, which is much shorter than reported uni-portal VATS operation time. For now, RATS has some drawbacks and is lacking of national practice guidelines, which, we believe, will be solved by technology development and large-scale randomized controlled trials. ?. PMID- 29587935 TI - [The Argument and Consensus of Lymphadenectomy on Lung Cancer Surgery]. AB - Lymph node metastasis is an important route of metastasis of lung cancer. Lymphadenectomy has become the standard surgical procedure for lung cancer. The way of intraoperative lymph node assessment also affects the prognosis and treatment strategy of lung cancer. In clinical practice, the way of intraoperative lymph node assessment ranges from selected lymph node biopsy to extended lymph node dissection. The advantages and disadvantages of different lymph node assessment are still controversial. In this article, the argument and consensus of lymphadenectomy on lung cancer operation are summarized. PMID- 29587936 TI - [Experience and Progress Processing Policy of Simultaneous Multiple Primary ?Lung Cancer]. AB - BACKGROUND: Simultaneity multiple primary lung cancer always is a rare disease, but in recent years due to the progress of the diagnosis and treatment means detection rate increased. This study summarized the clinical data of 31 cases of synchronous multiple primary lung cancer (sMPLC) analysis, further to explore the diagnosis, treatment and prognosis of MPLC. METHODS: Sum up the clinical data of 31 cases of simultaneous multiple primary lung cancer, the diagnostic method, surgical methods, pathology, were retrospectively analyzed. RESULTS: All the patients are thoracoscope surgery, no deaths. Thin high resolution computed tomography (CT) in preoperative found multiple lung nodules. Lesions located in the same side of the same period surgical treatment, the operation method is given priority to with under the thoracoscope lung + the lobectomy; Lesions located in bilateral, all staged operation, the time interval for 3 months-4 months. CONCLUSIONS: Thin layer distinguish CT preoperative diagnosis is the best way to simultaneous multiple primary lung cancer. Multiple primary lung cancer incidence of ipsilateral lung at the same time higher than that of bilateral lung (23:8), type, around 94%, the most common histology to adenocarcinoma, 80.6% (25/31). Primary lesions under thoracoscope lobectomy plus the lobectomy of secondary lesions is the most commonly used. PMID- 29587937 TI - [Diagnosis and Treatment for Multiple Primary Lung Cancer].

AB - BACKGROUND: Recently, the detectable rate of ground-glass opacity (GGO ) was significantly increased, a appropriate diagnosis before clinic treatment tends to be important for patients with GGO lesions. The aim of this study is to validate the ability of the mean computed tomography (m-CT) value to predict tumor invasiveness, and compared with other measurements such as Max CT value, GGO size, solid size of GGO and C/T ratio (consolid/tumor ratio, C/T) to find out the best measurement to predict tumor invasiveness. METHODS: A retrospective study was conducted of 129 patients who recieved lobectomy and were pathological confirmed as atypical adenomatous pyperplasia (AAH) or clinical stage Ia lung cance in our center between January 2012 and December 2013. Of those 129 patients, the number of patients of AAH, AIS, AIS and invasive adenocarcinoma were 43, 26, 17 and 43, respectively. We defined AAH and AIS as noninvasive cancer (NC), MIA and invasive adenocarcinoma were categorized as invasive cancer(IC). We used receiver operating characteristic (ROC) curve analysis to compare the ability to predict tumor invasiveness between m-CT value, consolidation/tumor ratio, tumor size and solid size of tumor. Multiple logistic regression analyses were performed to determine the independent variables for prediction of pathologic more invasive lung cancer. RESULTS: 129 patients were enrolled in our study (59 male and 70 female), the patients were a median age of (62.0+/-8.6) years (range, 44 to 82 years). The two groups were similar in terms of age, sex, differentiation (P>0.05). ROC curve analysis was performed to determine the appropriate cutoff value and area under the cure (AUC). The cutoff value of solid tumor size, tumor size, C/T ratio, m-CT value and Max CT value were 9.4 mm, 15.3 mm, 47.5%, -469.0 HU and -35.0 HU, respectively. The AUC of those variate were 0.89, 0.79, 0.82, 0.90, 0.85, respectively. When compared the clinical and radiologic data between two groups, we found the IC group was strongly associated with a high m-CT value, high Max CT value, high C/T ratio and large tumor size. Gender, solid tumor size, tumor size, C/T ratio, m-CT value and MaxCT value were selected factor for multivariate analysis, when using the preoperatively determined variables to predict the tumor invasiveness, revealed that tumor size, C/T ratio, m-CT value and Max CT value were independent predictive factors of IC. CONCLUSIONS: The musurements of Max CT value, GGO size, solid size of GGO and C/T ratio were significantly correlated with tumor invasiveness, and the evaluation of m-CT value is most useful musurement in predicting more invasive lung cancer.

PMID- 29587940 TI - [Exploration of Postoperative Follow-up Strategies for Early Staged NSCLC Patients on the Basis of Follow-up Result of 416 Stage I NSCLC Patients after Lobectomy]. AB - BACKGROUND: Currently, there is no consensus on the follow-up strategy (follow-up time interval and content) of non-small cell lung cancer (NSCLC) in the world, and the relevant clinical evidence is also very limited. In this study, we aimed to summarize the recurrence/metastasis sites and timings of stage I NSCLC patients based on their follow-up data, aiming to provide a basis of follow-up time interval and content for this group of patients. METHODS: We retrospectively analyzed the 416 stage I NSCLC patients that underwent continuous anatomic lobectomy between Jan. 2000 to Oct. 2013 in our prospective lung cancer database. According to the recurrence/metastasis sites and timings, the long term follow-up time interval and content were explored. RESULTS: The 5-yr disease free survival (DFS) and overall survival (OS) in the whole group were 82.4% and 85.4%, respectively. There were 76 cases (18.3%) had recurrence/metastasis during follow up, among which the most frequent site was pulmonary metastasis (21 cases, 5.0%), followed by brain metastasis (20 cases, 4.8%), bone metastasis (12 cases, 2.9%), and mediastinal lymph node metastasis (12 cases, 2.9%). Among the factors that could influence recurrence/metastasis, patients with pT2a suffered from a higher recurrence/metastasis rate compared to patients with pT1 (P=0.006), with 5-yr DFS being 73.8% and 87.3%, respectively (P=0.002), and the 5-yr OS being 77.7% and 90.3%, respectively (P=0.011). CONCLUSIONS: The commonest recurrence/metastasis sites of stage I NSCLC after anatomic lobectomy are lung, brain and mediastinal lymph nodes, the risk of recurrence/metastasis within 2 years were equal to that between 3 years and 5 years. The follow-up frequencies and content within 2 years could be adjusted according to T stages. PMID- 29587942 TI - [Postoperative Follow-up Should Not Be Neglected].

AB - BACKGROUND: Da Vinci Surgical System is one of the greatest inventions of the 20th century, which represents the development direction of the precise minimally invasive surgical techniques, the aim of this study was to comparing the short term outcomes between da Vinci robot-assisted lobectomy and video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer. METHODS: 45 pairs of non-small cell lung cancer patients underwent pulmonary lobectomy with da Vinci Robotic assisted thoracoscopic (RATS) and VATS approach during the same period from January 2014 to January 2017. The operative time, estimated blood loss (EBL), total number and total groups of dissected lymph nodes, postoperative duration of drainage, the first day volume of drainage, total volume of drainage were compared. RESULTS: No perioperative death and convertion to thoracotomy occured in both groups. There were significant difference between RATS group and VATS group in EBL [(50.30+/-32.33) mL vs (208.60+/-132.63) mL], the first day volume of drainage [(275.00+/-145.42) mL vs (347.60+/-125.80) mL], the dissected total number [(22.67+/-9.67) vs (15.51+/-5.41)] and total team [(6.31+/-1.43) vs (4.91+/-1.04)] of lymph node. There were no significant difference in other outcomes. CONCLUSIONS: RATS is safe and effective and took better short-outcomes than VATS in non-small cell lung cancer.

PMID- 29587946 TI - [Impact of Chronic Obstructive Pulmonary Disease on Risk of Recurrence in Patients with Resected Non-small Cell Lung Cancer]. AB - BACKGROUND: Lung cancer and chronic obstructive pulmonary disease (COPD) are both common diseases in respiratory system and the leading causes of deaths worldwide. The purpose of this study was to determine whether the severity of COPD affects long-term survival in non-small cell lung cancer (NSCLC) patients after surgical resection. METHODS: A retrospective research was performed on 421 consecutive patients who had undergone lobectomy for NSCLC. Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed. RESULTS: A total of 172 patients were diagnosed with COPD, 124 as mild (GOLD-1), 46 as moderate(GOLD-2), and 2 as severe (GOLD-3). The frequencies of recurrence were significantly higher in higher COPD grades group (P<0.001). Recurrence-free survival at five years were 78.1%, 70.4%, and 46.4% in Non-COPD, GOLD-1 COPD, and GOLD-2/3 COPD groups, respectively (P<0.001). In univariate analysis, age, gender, smoking history, COPD severity, tumor size, histology and pathological stage were associated with recurrence-free survival. Multivariate analyses showed that older age, male, GOLD 2/3 COPD, and advanced stage were independent risk factors associated with recurrence-free survival. CONCLUSIONS: NSCLC patients with COPD are at higher risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor. The severity of COPD based on pulmonary function test can be a useful indicator to identify patients at high risk for recurrence. Therefore, it can contribute to adequate selection of the appropriate individualized treatment.

PMID- 29587948 TI - [Analysis of Prolonged Hospitalizations (Longer than 7 days): 115 Lung Cancer ?Patients after Video Assistant Thoracic Surgery (VATS)]. AB - BACKGROUND: Thoracoscopic surgery has gradually become the major procedure for lung cancer surgery in our department. Its characteristics are minimal trauma and quick recovery, which make approximately 90% of patients discharge from the hospital after surgery. However, the postoperative complications still happen now and then. We analyzed the patients who had been hospitalized for longer than 7 days after thoracoscopic lung cancer surgery, aiming to summarize the types and risk factors of complications, and improve postoperative safety of patients. METHODS: The data were come from the prospective database of Thoracic Surgery Unit One in Peking Cancer Hospital, and patients that underwent thoracoscopic pulmonary surgery between Jan. 2010 and Dec. 2014 with length of stay more than 7 days were included in the study. The classifications of the complications were investigated and graded as mild or severe complications according to modified Claviengrading, the relationship between clinical factors and degrees of complications was also analyzed. RESULTS: The hospitalization of 115 cases were longer than 7 days after surgery, accounting for 10.3% (115/1,112) of the whole patients that underwent surgery during the same period. Eighty-one cases had mild complications, accounting for 7.3% (81/1,112) of the whole cases that underwent surgery during the same period and 70.4% (81/115) of the cases with prolonged length of stay; the proportions of severe complications in both groups were 3.1% (34/1,112) and 29.6% (34/115), respectively; and the proportions of complications that caused perioperative deaths were 0.18% (2/1112) and 1.7% (2/115), respectively. Among all the postoperative complications, the most common was air leakage for more than 5 days after surgery, with a total of 20 cases (1.8% and 17.4%). The other common complications were: atelectasis (19 cases, 1.7% and 16.5%), pulmonary infection (18 cases, 1.6% and 15.7%), etc. The less common complications was bronchopleural fistula (4 cases, 0.36% and 3.5%) with very high risk, and 2 cases died perioperatively due to the combination of acute respiratory distresssyndrome (ARDS). In the clinical factors, only preoperative low pulmonary function (FEV1%<70%) was the potential risk factor for postoperative severe complications (45.8% vs 23.6%, P=0.038). There was no significant difference either regarding the 5 year disease free survival or the 5 year overall survival between mild complication group and severe complication group, with 5 year DFS being 52.2% and 51.9%, respectively (P=0.894) , and 5 year overall survival being 64.0% and 53.5%, respectively (P=0.673). CONCLUSIONS: Continuous postoperative air leakage, atelectasis and pulmonary infections were the major causes for prolonged hospitalization after thoracoscopic surgery for lung cancer, and bronchopleural fistula was the most perilous complications. Patients with low preoperative pulmonary function were more likely to have severe postoperative complication, however, this would not influence the long term survival of the patients.

AB - BACKGROUND: Bronchial pleural fistula (BPF) is a common complication after thoracic surgery for lung resection. Clinical treatment is complex and the effect is poor. The treatment of BPF after lung resection has plagued thoracic surgeons. We reviewed retrospectively the clinical and follow-up data of 6 patients in our hospital who underwent the omentum transplantation in thorax to cover bronchial stump as treatment of BPF after pulmonary resection to analyze why BPF occurs and describe this treatment method. We intend to discuss and evaluate the feasibility, safety and small sample success rate ofthis treatment method. METHODS: During August 2016 to February 2018, six patients in our hospital underwent remedial open thoracotomy and omentum transplantation in pleura space to cover bronchial stump as treatment of bronchopleural fistula after pulmonary resection. Four patients had undergone a prior pneumonectomy and two patients had undergone a prior lobectomy (the residual lungs were resected with the main bronchus cut by endoscopic stapler during the reoperation). The bronchial stumps were sutured by 4-0 string with needle and covered by omentums, which were transplanted in pleura space from the cardiophrenic angle. Postoperatively, the pleura space was irrigated and drained. Summarize the clinical effect and technique learning points. RESULTS: The patients were all males, aged 61 to 73 years (median age: 66). BPF occurred from postoperative day 10 to 45 (median postoperative day 25). The reoperation was finished in 80 mins-150 mins (median 110 mins). Total blood loss was 200 mL-1,000 mL (median 450 mL). These patients were discharged on postoperative day 12-17 (median 14 days), and there was no more complications associated with bronchopleural fistula. All six patients' bronchial stumps were well closed (100%) and have recovered well during the follow-up period, which lasted 1 month-18 months. CONCLUSIONS: Remedial operation should be performed as soon as possible when BPF after pulmonary resection diagnosed. Excellent prognoses can be achieved by omentum which is easy to get transplanted in thorax to cover bronchial stump as treatment in patients with BPF after pulmonary resection those who can tolerate reoperation.

AB - Huntington's disease is an inherited neuropsychiatric disorder characterized by a triad of symptoms: motor, cognitive and psychiatric. Psychiatric symptoms occur prior to the motor symptoms in approximately 50% of the cases, and knowledge of the psychiatric symptoms is essential in making an early diagnosis. In this article, we argue that further knowledge of the genetic background of Huntington's disease may contribute to a better understanding of the polygenetic psychiatric diseases such as schizophrenia and bipolar affective disorder. PMID- 29587953 TI - [Nrf2 and Keap1 Abnormalities in 104 Lung Adenocarcinoma Cases and Association with Clinicopathologic Features]. AB - BACKGROUND: There are significantly interindividual variations of the expression level of nuclear factor erythroid-2-related factor 2 (Nrf2) and/or Kelch-like ECH associated protein 1 (Keap1) in our previous studies. It has been proven that Nrf2 or Keap1 is related to resistance of chemotherapeutic drugs and/or epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). However, the expression of Nrf2 and Keap1 in lung adenocarcinoma patients with different "driver gene" is not clear. The aim of this study is to investigate the protein expression level of Nrf2 and Keap1 in lung adenocarcinoma and to elucidate the correlation between Nrf2 or Keap1 expression and the status of EGFR gene mutation and to determine the effects of Nrf2 and Keap1 on the patients. METHODS: Immunohistochemical analysis of Nrf2 and Keap1 in tumor specimens was performed in a total of 104 lung adenocarcinoma patients with the status of EGFR gene mutations or EGFR wide-type. RESULTS: The Nrf2 positive rate was 71.2% and Keap1 high expression rate was 34.6% in 104 patients. The Nrf2 positive rate significantly correlated with gender, stage and status of EGFR gene mutation (P<0.05), but not with age, smoking, differentiation and subtype of lung adenocarcinoma (P>0.05). The high expression of Keap1 was not significantly correlated with gender, age, smoking, differentiation, subtype of lung adenocarcinoma and status of EGFR gene mutation (P>0.05). The progression -free survival (PFS) and overall survival (OS) of the patients treated by EGFR-TKIs were significantly correlated with the expression level of Nrf2, but not with Keap1. The PFS and OS of the patients with Nrf2 high expression were significantly shorter than the patients with low/negative expression (P<0.05). Furthermore, Nrf2 high expression was the independent predictive factor for EGFR TKIs induced PFS and OS (P<0.05). CONCLUSIONS: The Nrf2 positive rate significantly correlated with the status of EGFR gene mutation in lung adenocarcinoma. The Nrf2 high expression significantly correlated with PFS and OS of EGFR-TKIs. Therefore, Nrf2 may be a biomarker for predicting response of EGFR TKIs and a potential target for overcoming resistance of EGFR-TKIs. PMID- 29587955 TI - [Small amounts of milk added to coffee or tea can be allowed before surgery]. AB - The ingestion of milk is not allowed within six hours before elective procedures requiring anaesthesia or sedation, because milk is considered a solid food. However, the impact of milk suspended in coffee or tea consumed up to two hours before anaesthesia is less certain, yet fasting guidelines demand surgery to be delayed or rescheduled. Studies investigating ingestion of liquids with small amounts of milk have not demonstrated delayed emptying of the stomach, thereby increasing the risk of aspiration in elective procedures. Maybe it is time to adjust the fasting recommendations. PMID- 29587956 TI - [The blood-brain barrier in ageing persons]. AB - Brain capillary endothelial cells (BECs) form the ultra-tight blood-brain barrier (BBB). The permeability of the BBB increases with increasing age and neurovascular and neurodegenerative diseases. Major defects of the BBB can be initiated by increased permeability to plasma proteins in small arteriosclerotic arteries and release of proteins from degenerating neurons into the brain extracellular space. These proteins deposit in perivascular spaces, and subsequently negatively influence the BECs leading to decreased expression of barrier proteins. Detection of BBB defects by the use of non-invasive techniques is relevant for clinical use in settings with advanced age and severe brain disorders. PMID- 29587957 TI - [Epilepsy surgery].

Furthermore, the first results from the research projects are presented. It is concluded, that early detection teams could be introduced throughout Denmark with great advantage. PMID- 29587959 TI - CUP Syndrome-Metastatic Malignancy with Unknown Primary Tumor. AB - BACKGROUND: 2-4% of newly diagnosed cases of malignant disease involve cancer of unknown primary (CUP). This mixed entity is one of the 6 most common types of malignant disease in Germany. Highly refined treatment strategies can now be offered to patients with CUP. METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed with an emphasis on articles from the past decade. The current guidelines and recommendations of specialty societies were also considered in the evaluation. RESULTS: CUP most commonly manifests itself as metastases to the lymph nodes, lungs, liver, or bones. With the aid of imaging studies, including functional hybrid imaging and further medical examination, a primary tumor can be discovered in up to 40% of patients initially diagnosed with CUP. Immunohistochemistry guided by histomorphology often enables precise characterization of the lesion and can be supplemented, in selected cases, by molecular-genetic diagnostic evaluation. The most commonly detected types of primary tumor are cancers of the lung, pancreas, liver, and biliary system. For patients with local metastases, surgical resection or radiotherapy with curative intent is usually indicated, sometimes in the framework of a multimodal treatment concept. The median 2-year survival of patients with disseminated CUP is only 20%. For such patients, specific types of systemic therapy are recommended on the basis of the diagnostic characterization of the disease. Immune-modulatory antibodies can be effective, particularly in the treatment of CUP that has been characterized with biomarkers, but should still be considered experimental at present. CONCLUSION: A combination of conventional and innovative diagnostic methods enables the provision of highly refined therapeutic strategies to patients with CUP who are undergoing treatment in interdisciplinary cancer centers. PMID- 29587960 TI - Cluster-Randomized Studies. AB - BACKGROUND: Cluster-randomized trials (CRT) are needed to compare interventions that are allocated to entire groups of subjects, rather than to individuals. Publications about CRT have become steadily more common over the past decade. Readers of such publications should be able to categorize and interpret the findings of CRT correctly while considering the methodological requirements applicable to this type of study. METHODS: This review is based on a selection of pertinent literature and on the authors' expertise. CRT-specific methodological aspects of the planning, performance, and interpretation of studies are discussed. RESULTS: Readers of publications on CRT should check whether due consideration has been given to correlations within and between the clusters during the planning of the study. These correlations enable the determination whether persons within a cluster resemble each other more closely, or respond more similarly to the study intervention, than persons drawn from different clusters. It should also be checked whether the randomization for the study has been carried out with such methods as stratification and covariate-adjusted randomization. CRT can be analyzed on either the individual or the cluster level. The rationale for the choice of a clusterrandomized design should be explained, and intracluster correlation coefficients (ICC) should be reported as an aid to the planning of future studies. Particular requirements are also described in an extended version of the CONSORT guidelines that has been developed specifically for CRT. CONCLUSION: Readers of publications on CRT should be aware of the special requirements mentioned above with respect to the design, performance, and analysis of this type of study as opposed to individually randomized studies. If no special techniques are applied in the design, performance, and analysis of a CRT, or if the assumptions underlying each of these steps have not been properly checked, then the findings of the study may well be misleading. PMID- 29587961 TI - Liquid Biopsy in Tumor Genetic Diagnosis. AB - BACKGROUND: Liquid biopsy involves the analysis of cell-free nucleic acids, mainly circulating free DNA (cfDNA), in bodily fluids such as blood. The obtaining of specimens is easier for patients and less invasive than tissue biopsy, but the method has certain limitations. METHODS: This review is based on pertinent publications retrieved by a selective literature search. RESULTS: Because the concentration of cfDNA in plasma is less than 0.001%, special amplifying techniques must be used to enable a search for specific mutations. Liquid biopsy can be used in patients with non-small cell lung cancer (NSCLC) if no tissue is available for biopsy; when performed for this indication, it has 67% sensitivity and 94% specificity. If liquid biopsy does not reveal a mutation, this may be due either to the absence of the mutation in the tumor or to the inadequate sensitivity of the measuring technique. This uncertainty associated with negative findings can be reduced by the simultaneous demonstration of reference mutations derived from a primary tumor tissue analysis. In comparison to tissue studies, the search for tumor-specific mutations by liquid biopsy is 70% sensitive and 69% specific; this corresponds to a positive predictive value of 86% and a negative predictive value of 46%. CONCLUSION: Liquid biopsy and tumor tissue analysis are complementary, rather than alternative, techniques for therapeutically relevant genetic investigation of tumors. Comparative studies are needed so that further indications can be determined for liquid biopsy in the diagnostic evaluation of cancer.

AB - BACKGROUND: Laparoscopic right hemicolectomy (LRHC) techniques have varied in the approach to anastomosis. We compared outcomes of laparoscopic right hemicolectomy with extracorporeal anastomosis (ECA) versus intracorporeal anastomosis (ICA). METHODS: We retrospectively reviewed all LRHCs conducted at Richmond Hospital between January 2015 and October 2017. We compared the demographic, pathologic, intraoperative, and postoperative data. RESULTS: 74 LRHCs were included during the study period: 56 ECA and 18 ICA. The groups were comparable in age, gender, tumor staging, and tumor location. Incidence of clinical ileus was significantly less for ICA (0% vs. 21%, p = 0.032). Mean length of stay was significantly shorter for ICA (3.13 vs. 4.82 days, p = 0.003). There was no difference between ICA and ECA in mean operative time (158 vs. 145 min, p = 0.087), surgical site infections (6% vs. 4%, p = 1.0), emergency department visits within 30 days (5% vs. 6%, p = 1.0), and hospital readmission within 30 days (4% vs 0%, p = 1.0). There were no incidences of anastomotic leaks, perioperative deaths, or cardiopulmonary complications in either group. CONCLUSIONS: An ICA approach to LRHC results in shorter hospital stay and decreased rates of clinical ileus.

AB - AIM: To assess the intra- and interobserver reliability and agreement of muscular atrophy and fatty degeneration of the gluteal muscles on magnetic resonance imaging (MRI) in patients with end-stage osteoarthritis of the hip. MATERIALS AND METHODS: Thirty-nine patients with end-stage osteoarthritis of the hip, who scheduled for hip replacement surgery, were included in the study. The cross sectional areas of the gluteus medius and minimus muscles were manually circumscribed and automatically calculated, while intramuscular fatty degeneration was assessed using the semi-quantitative classification system of Goutallier. Two independent observers performed all the evaluations. RESULTS: Good agreement and excellent reliability were found for the cross-sectional areas of the gluteus medius and gluteus minimus (intraclass correlation coefficient [ICC] for intra-observer 0.97 and 0.93, ICC for interobserver 0.98 and 0.95). Fair reliability was found for fatty degeneration of the gluteus muscles (mean kappa 0.23 and mean prevalence-adjusted kappa 0.53). The average proportion of agreement for the raters was 0.71. CONCLUSION: The present study demonstrated substantial agreement and excellent intra- and interobserver reliability for the measurements of the cross-sectional areas of the gluteus medius and gluteus minimus. Assessment of fatty degeneration had fair intra- and interobserver reliability, but acceptable agreement. PMID- 29587968 TI - Phakic intraocular lenses: Where are we now? PMID- 29587969 TI - Femtosecond laser-assisted cataract surgery in eyes with foldable anterior or posterior chamber phakic intraocular lenses. AB - We describe a technique for the application of femtosecond laser-assisted cataract surgery in eyes with cataract and previous implantation of a foldable anterior or posterior chamber phakic intraocular lens (pIOL). In 2 eyes with an anterior chamber pIOL (angle-supported Acrysof Cachet) and 3 eyes with a posterior chamber pIOL (2 eyes with an Implantable Collamer Lens pIOL; 1 eye with a Phakic Refractive Lens), a femtosecond laser was used to create a capsulotomy, perform lens fragmentation, and create corneal incisions with the pIOL in situ. In all cases, the capsulotomy was created successfully. Lens fragmentation was complete in 4 eyes and incomplete in 1 eye, where trapped cavitation bubbles in the space between the posterior chamber pIOL and anterior lens capsule were evident as a result of a shallow vault of the pIOL.

AB - PURPOSE: To evaluate the levels of ischemia-modified albumin (IMA) in relation to oxidant-antioxidant profiles in the serum, aqueous, and lens in cataract patients. SETTING: Department of Ophthalmology, Menoufia University, Shebin El Kom, Menoufia, Egypt. DESIGN: Prospective case series. METHODS: Patients were divided into 2 groups. The cataract (study) group comprised patients with senile cataract and the control group, age- and sex-matched healthy persons. Patients with systemic disease or cataract formation secondary to identifiable causes were excluded. In all cases, a complete history was taken and a clinical examination was performed. In the cataract group, the lens was examined, and the cataract type and severity were graded. Blood levels of catalase, malondialdehyde (MDA), superoxide dismutase (SOD), and IMA were measured in all participants and in the aqueous and lens lysate of cataract patients. RESULTS: Each group comprised 30 participants. Cataract patients had significant higher levels of serum MDA and IMA than the control group but had lower levels of serum catalase and SOD. Patients with cortical cataracts had higher level of serum IMA, aqueous catalase, and SOD levels patients with nuclear cataracts but had a lower level of lens SOD. There was a significant positive correlation between serum MDA and the patient's age and serum catalase levels. CONCLUSION: Patients with cortical cataract had increased local oxidative stress and diminished antioxidant activity compared with systemic oxidative activity, which was not the same in patients with nuclear cataract. PMID- 29587971 TI - Prevalence of meibomian gland dysfunction at the time of cataract surgery. AB - PURPOSE: To determine the incidence of meibomian gland dysfunction and quantify subjective dry-eye symptoms in cataract surgery candidates. SETTING: Brest University Hospital, Brest, France. DESIGN: Prospective case series. METHODS: Patients having cataract surgery between November 2015 and June 2016 completed the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire. Lipid layer thickness and partial blink rate measurements as well as gland structure assessment were performed using the Lipiview Ocular Surface Interferometer. A slitlamp examination determined tear breakup time; the quantity and quality of the meibomian gland secretion were determined using the Meibomian Gland Evaluator. RESULTS: The study comprised 342 eyes of 180 patients. The mean lipid layer thickness was 72.5 nm +/- 19.91 (SD). In patients with a SPEED score lower than 8, the mean lipid layer thickness was 77.5 +/- 19.48 nm. In patients with a SPEED score of 8 or higher, the mean lipid layer thickness was 58.5 +/- 19.58 nm. The difference in lipid layer thickness between SPEED score groups was statistically significant (P < .05). Fifty-two percent of patients had meibomian gland dysfunction, and 56% had meibomian gland atrophy equal to or more than Arita grade 1. Meibomian gland function correlated significantly with lipid layer thickness, symptoms, age, and gland atrophy (P < .05). CONCLUSIONS: The incidence of meibomian gland dysfunction was high in patients presenting for cataract surgery. Fifty percent of patients with meibomian gland dysfunction were asymptomatic. Correct criteria and meibomian function and structure assessment are critical to diagnosis. Comprehensive preoperative testing should routinely include evaluation of meibomian function. PMID- 29587972 TI - Comparative analysis of visual outcomes with 4 intraocular lenses: Monofocal, multifocal, and extended range of vision. AB - PURPOSE: To compare the visual acuity, refractive outcomes, and quality of vision in patients with bilateral implantation of 4 intraocular lenses (IOLs). SETTINGS: Department of Neurosciences, Biomedicine and Movement Sciences, Eye Clinic, University of Verona, Verona, and Carones Ophthalmology Center, Milano, Italy. DESIGN: Prospective case series. METHODS: The study included patients who had bilateral cataract surgery with the implantation of 1 of 4 IOLs as follows: Tecnis 1-piece monofocal (monofocal IOL), Tecnis Symfony extended range of vision (extended-range-of-vision IOL), Restor +2.5 diopter (D) (+2.5 D multifocal IOL), and Restor +3.0 D (+3.0 D multifocal IOL). Visual acuity, refractive outcome, defocus curve, objective optical quality, contrast sensitivity, spectacle independence, and glare perception were evaluated 6 months after surgery. RESULTS: The study comprised 185 patients. The extended-range-of-vision IOL (55 patients) showed better distance visual outcomes than the monofocal IOL (30 patients) and high-addition apodized diffractive-refractive multifocal IOLs (P <= .002). The +3.0 D multifocal IOL (50 patients) showed the best near visual outcomes (P < .001). The +2.5 D multifocal IOL (50 patients) and extended-range of-vision IOL provided significantly better intermediate visual outcomes than the other 2 IOLs, with significantly better vision for a defocus level of -1.5 D (P < .001). Better spectacle independence was shown for the +2.5 D multifocal IOL and extended-range-of-vision IOL (P < .001). CONCLUSIONS: The extended-range-of vision IOL and +2.5 D multifocal IOL provided significantly better intermediate visual restoration after cataract surgery than the monofocal IOL and +3.0 D multifocal IOL, with significantly better quality of vision with the extended range-of-vision IOL. PMID- 29587973 TI - Improved utilization of operating room time for trainee cataract surgery in a public hospital setting. AB - PURPOSE: To examine the effect of group goal and group performance theories on operating room efficiency in resident-performed cataract surgery. SETTING: Zuckerberg San Francisco General Hospital and Trauma Center, Department of Ophthalmology, University of California, San Francisco, California, USA. DESIGN: Prospective case series. METHODS: This study assessed 4 specific segments of operating room utilization identified as room-to-incision time, incision-to-close time, close-to-exit time, and room turnover time. The time segments were measured for resident-performed cataract cases before the proposed intervention. Then, group goals were set for ideal times of each utilization segment. Behaviors of the surgery, anesthesia, nursing, pharmacy, and housekeeping teams that would improve group performance were identified. Utilization segments were measured again after the intervention. RESULTS: The time segments were measured for 134 resident-performed cataract cases before the proposed intervention and again after the intervention for 136 resident-performed cataract cases. Before the intervention, the mean overall case time was 55 minutes, allowing for 10 cases in a 10-hour day. After the intervention, the mean overall case time was 46 minutes, allowing for 13 cases in a 10-hour day. The decrease in postintervention times for overall case time, room-to-incision time, and close-to-exit time were statistically significant. CONCLUSIONS: Operating room utilization for resident performed cataract surgery was enhanced by setting group goals. A multidisciplinary effort to enhance group performance through behavior modification can be implemented immediately and improve efficiency without compromising patient safety or resident teaching. PMID- 29587974 TI - Macular photostress and visual experience between microscope and intracameral illumination during cataract surgery. AB - PURPOSE: To evaluate macular photostress and visual experience between coaxial microscope illumination versus oblique intracameral illumination during cataract surgery. SETTING: Gachon University Gil Hospital, Incheon, South Korea. DESIGN: Prospective case series. METHODS: Consecutive patients who had cataract surgery using microscope illumination and intracameral illumination were included. The patients were asked to complete a questionnaire (seeing strong lights, feeling photophobia, feeling startled (fright) when seeing lights, seeing any colors, seeing any instruments or surgical procedures, and estimating intraoperative visual function) designed to describe their cataract surgery experience. The images projected on the retina of the model eye (rear view) with artificial opaque fragments in the anterior chamber during simulating cataract surgery were compared between the 2 illumination types. RESULTS: Sixty patients completed the questionnaire. Scores for strong lights, photophobia, fright, and color perception were significantly higher with microscope illumination than with intracameral illumination (all P < .001). More patients preferred the intracameral illumination (45 [75.0%]) to the microscope illumination (13 [21.7%]). In the rear-view images created in a model eye, only the bright microscope light in the center was seen without any lens image in the microscope illumination. However, in the intracameral illumination, the less bright light from the light pipe in the periphery and the lens fragments were seen more clearly. CONCLUSIONS: In a view of the patients' visual experience, oblique intracameral illumination caused less subjective photostress and was preferred over coaxial microscope illumination. Objective findings from the model-eye experiment correlated to the result of visual experience. PMID- 29587975 TI - Astigmatic correction by intrastromal astigmatic keratotomy during femtosecond laser-assisted cataract surgery: Factors in outcomes. AB - PURPOSE: To evaluate the 6-month outcomes of femtosecond laser astigmatic keratotomy (AK) combined with femtosecond laser-assisted cataract surgery and identify factors affecting the efficacy of astigmatic correction. SETTING: Seoul St. Mary's Hospital, Catholic University of Korea, Seoul, South Korea. DESIGN: Retrospective case series. METHODS: Femtosecond laser AK was performed during femtosecond laser-assisted cataract surgery. The keratometric astigmatism, refractive cylinder, corneal hysteresis (CH), and corneal resistance factor (CRF) were measured preoperatively and postoperatively at 1 week, 2 months, and 6 months. Vector analysis to evaluate the 6-month outcomes of femtosecond laser AK and univariable regression analysis to determine the factors influencing the correction index were performed. RESULTS: The study enrolled 89 eyes of 89 patients. The stigmatism type, CH, CRF, and absolute angle of error showed significant correlations with the correction index (P = .041, P = .029, P = .044, and P < .001, respectively). There was a significant difference in the correction index and no difference in keratometric astigmatism between with-the-rule (WTR), against-the-rule (ATR), and oblique astigmatism (P = .044). The keratometric astigmatism with ATR and oblique astigmatism (0.66 diopter [D] +/- 0.42 [SD] and 0.46 +/- 0.27 D, respectively) was significantly lower than the refractive cylinder (0.92 +/- 0.56 D and 0.78 +/- 0.43 D, respectively) (P < .05); this was not the case for WTR astigmatism. CONCLUSIONS: The efficacy of femtosecond laser AK was affected by the biomechanical properties of the cornea and astigmatism type. Further studies incorporating the individual biomechanical properties of the cornea and total corneal astigmatism in a nomogram are recommended. PMID- 29587976 TI - Effect of supplementary implantation of a sulcus-fixated intraocular lens in patients with negative dysphotopsia. AB - PURPOSE: To evaluate whether the outcome of negative dysphotopsia treatment by implantation of a Sulcoflex intraocular lens (IOL) can be understood using individual biometry and optical modeling data. SETTING: University Eye Clinic, Maastricht University Medical Centre, Maastricht, the Netherlands. DESIGN: Retrospective case series. METHODS: Patients with negative dysphotopsia were treated with supplementary implantation of a sulcus-fixated IOL. Preoperative and postoperative ray-tracing optical models of eyes with negative dysphotopsia were constructed in the Zemax Optic Studio program using individual biometric data. The relationship between biometric parameters, ray-tracing data, and the course of negative dysphotopsia was evaluated. RESULTS: The study comprised 8 patients (10 eyes). After surgery, negative dysphotopsia resolved completely in 6 eyes, partially in 2 eyes, and persisted in 2 eyes. There was no relationship between the course of negative dysphotopsia and age, IOL power, or individual biometry results other than a larger angle kappa that was observed in 2 patients with persistent negative dysphotopsia after surgery. Preoperative ray-tracing models showed a decrease in light irradiance at the periphery relative to the center of visual field. After sulcus-fixated IOL implantation, this decrease partially resolved, in particular, for a small pupil aperture (P < .05), and it was more prominent in patients in whom negative dysphotopsia resolved completely than in those with partial or persistent negative dysphotopsia (P = .065 at 1.5 mm aperture). CONCLUSIONS: Of all individual biometry results, only angle kappa showed a relationship with the course of negative dysphotopsia. In patient specific optical modeling of sulcus-fixated IOL implantation, the increase in simulated light irradiance at the periphery was related to the course of negative dysphotopsia. PMID- 29587977 TI - Influence of surface light scattering and glistenings of intraocular lenses on visual function 15 to 20 years after surgery. AB - PURPOSE: To assess the long-term influence of surface light scattering and glistenings of hydrophobic acrylic (Acrysof), silicone, and poly(methyl methacrylate) (PMMA) intraocular lenses (IOLs) on visual function. SETTING: Eleven surgical sites, Japan. DESIGN: Retrospective case series. METHODS: Patients who had cataract surgery with implantation of a hydrophobic acrylic, silicone, or PMMA IOL from 1994 to 2000 were examined. Silicone and PMMA IOLs were not restricted to specific manufacturers or models. Patients were included if their corrected distance visual acuity (CDVA) within 3 months postoperatively (baseline CDVA) was 20/25 or better. The CDVA, contrast sensitivity, degree of surface light scattering measured with Pentacam densitometry, and glistening grades were recorded at the patient's latest visit. RESULTS: Of the eyes, 31 had a hydrophobic acrylic IOL, 37 a silicone IOL, and 30 a PMMA IOL. Surface light scattering and glistenings were significantly greater with the hydrophobic acrylic IOL than with silicone and PMMA IOLs (P < .0001). The CDVA at the latest visit as well as the changes in CDVA from the baseline to the latest visit did not differ between the IOLs and was unaffected by surface light scattering and glistenings, as was the contrast sensitivity. CONCLUSIONS: The hydrophobic acrylic IOL was associated with a significantly greater level of surface light scattering and glistenings than the silicone IOLs and PMMA IOLs 15 to 20 years postoperatively. However, the optical phenomena within the optics of the hydrophobic acrylic IOL did not influence the patients' visual function. PMID- 29587978 TI - Mechanical model of human eye compliance for volumetric occlusion break surge measurements. AB - PURPOSE: To develop a mechanical model of human eye compliance for volumetric studies. SETTING: Alcon Research, Ltd., Lake Forest, California, USA. DESIGN: Experimental study. METHODS: Enucleated human eyes underwent pressurization and depressurization cycles with peak intraocular pressures (IOPs) of 60 to 100 mm Hg; anterior chamber pressure and volume changes were measured. Average net volume change curves were calculated as a function of IOP for each eye. Overall mean volumes were computed from each eye's average results at pressure points extrapolated over the range of 5 to 90 mm Hg. A 2-term exponential function was fit to these results. A fluid chamber with a displaceable piston was created as a mechanical model of this equation. A laser confocal displacement meter was used to measure piston displacement. A test bed incorporated the mechanical model with a mounted phacoemulsification probe and allowed for simulated occlusion breaks. Surge volume was calculated from piston displacement. RESULTS: An exponential function, V = C1 * exp(C2 * IOP) + C3 * exp(C4 * IOP) - V0, where V, the volume, was fit to the final depressurization curve obtained from 15 enucleated human eyes. The C1 through C4 values were -0.07141, -0.23055, -0.14972, and -0.02006, respectively. The equation was modeled using a piston system with 3 parallel springs that engaged serially. The mechanical model mimicked depressurization curves observed in human cadaver eyes. CONCLUSION: The resulting mechanical compliance model measured ocular volumetric changes and thus would be helpful in characterizing the postocclusion break surge response.

AB - Autologous tissue from correction of myopia with small-incision lenticule extraction in 1 eye of a patient was used to enhance corneal curvature in the contralateral eye, in which a corneal ulcer had flattened the cornea.

AB - Recent research has provided improved genome-level views of diversity across global honey bee populations, the gut microbiota residing within them, and the expanding pathosphere challenging honey bees. Different combinations of bee/microbiota/pathosphere genome complexes may explain regional variation in apiculture productivity and mortality. To understand this, we must consider management and research approaches in light of a hologenome paradigm: that honey bee fitness is determined by the composite bee and microbiota genomes. Only by considering the hologenome can we truly interpret and address impacts from the pathosphere, pesticides, toxins, nutrition, climate and other stressors affecting bee health. PMID- 29587998 TI - Causes of variation in wild bee responses to anthropogenic drivers. AB - Anthropogenic change can have large impacts on wild bees and the pollination services they provide. However, the overall pattern of wild bee response to drivers such as land-use change, pesticides, pathogens, and climate change has been one of variability in both the magnitude and directionality of responses. We argue that two causes contribute to this variation. First, different species exhibit differential responses to the same anthropogenic drivers. Second, these anthropogenic drivers vary in type and magnitude that will drive variation in bee responses. For this second issue, we focus on land-use change, the most well studied driver. We conclude by discussing how understanding species-level responses and the magnitude of land-use change can make bee conservation more effective. PMID- 29587999 TI - From puddles to planet: modeling approaches to vector-borne diseases at varying resolution and scale. AB - Since the original Ross-Macdonald formulations of vector-borne disease transmission, there has been a broad proliferation of mathematical models of vector-borne disease, but many of these models retain most to all of the simplifying assumptions of the original formulations. Recently, there has been a new expansion of mathematical frameworks that contain explicit representations of the vector life cycle including aquatic stages, multiple vector species, host heterogeneity in biting rate, realistic vector feeding behavior, and spatial heterogeneity. In particular, there are now multiple frameworks for spatially explicit dynamics with movements of vector, host, or both. These frameworks are flexible and powerful, but require additional data to take advantage of these features. For a given question posed, utilizing a range of models with varying complexity and assumptions can provide a deeper understanding of the answers derived from models. PMID- 29588000 TI - Bee nutrition and floral resource restoration. AB - Bee-population declines are linked to nutritional shortages caused by land-use intensification, which reduces diversity and abundance of host-plant species. Bees require nectar and pollen floral resources that provide necessary carbohydrates, proteins, lipids, and micronutrients for survival, reproduction, and resilience to stress. However, nectar and pollen nutritional quality varies widely among host-plant species, which in turn influences how bees forage to obtain their nutritionally appropriate diets. Unfortunately, we know little about the nutritional requirements of different bee species. Research must be conducted on bee species nutritional needs and host-plant species resource quality to develop diverse and nutritionally balanced plant communities. Restoring appropriate suites of plant species to landscapes can support diverse bee species populations and their associated pollination ecosystem services. PMID- 29588001 TI - Insect-pathogen interactions: contribution of viral adaptation to the emergence of vector-borne diseases, the example of chikungunya. AB - The emergence or re-emergence of vector borne diseases represents a major public health problem. In general, therapeutic or prophylactic treatments along with vaccines are missing or inefficient, emphasizing the need for increased control of vector populations. Understanding the interactions of human pathogens with their insect vectors will aid us in our understanding of viral emergence and the dynamics of these events. Chikungunya virus (CHIKV) is a mosquito-borne virus that typically causes incapacitating arthralgia, rash, and fever. It is mainly transmitted by Aedes aegypti and secondarily by Aedes albopictus. Since its emergence in 2004, CHIKV has continued to spread globally due in large part to an enhanced transmission of the virus by the vector Ae. albopictus. Ae. albopictus adaptive mutations modulated by epistatic interactions have modified CHIKV transmission and thus the global spread and dynamics of this disease. PMID- 29588002 TI - Pesticides and pollinators: a context-sensitive policy approach. AB - I examine recent policymaking efforts in the United States (US) that seek to improve how risks posed by pesticides to insect pollinators are assessed and managed. Utilizing the case of ongoing honey bee die-offs, I argue for a context sensitive policy framework. From a scientific perspective, this entails not ignoring the uncertain knowledge emerging from laboratory and field studies regarding the indirect effects of low levels of certain insecticides in combination with other factors. From a social scientific perspective, policy initiatives to build partnerships between growers and beekeepers toward mitigating exposure to pesticides are crucial, and need to acknowledge barriers to the adoption of best management practices as well as a historically established asymmetry between growers and beekeepers in the pollination industry. PMID- 29588003 TI - Back to the future: the sterile insect technique against mosquito disease vectors. AB - With the global burden of mosquito-borne diseases increasing, and some conventional vector control tools losing effectiveness, the sterile insect technique (SIT) is a potential new tool in the arsenal. Equipment and protocols have been developed and validated for efficient mass-rearing, irradiation and release of Aedines and Anophelines that could be useful for several control approaches. Assessment of male quality is becoming more sophisticated, and several groups are well advanced in pilot site selection and population surveillance. It will not be long before SIT feasibility has been evaluated in various settings. Until perfect sexing mechanisms exist, combination of Wolbachia induced phenotypes, such as cytoplasmic incompatibility and pathogen interference, and irradiation may prove to be the safest solution for population suppression. PMID- 29588004 TI - Improving the future of honey bee breeding programs by employing recent scientific advances. AB - A recent abundance of studies investigating causes of honey bee (Apis mellifera) colony losses has led to enhanced recommendations in management practices with particular emphasis on breeding for resistant bee stocks. Here we review the latest advances in research which could improve the future of breeding programs. We discuss diversity in colonies particularly in breeding programs, giving special emphasis to recent improvement in cryopreservation of honey bee germplasm. We also review factors that affect the health and reproductive quality of queens and drones. We briefly discuss how techniques developed by scientists are finding more regular usage with breeders in the assessment of reproductive caste health and quality and in determining best management practices for breeding programs. PMID- 29588005 TI - Nutrition, immunity and viral infections in honey bees. AB - Viruses and other pathogens can spread rapidly in social insect colonies from close contacts among nestmates, food sharing and periods of confinement. Here we discuss how honey bees decrease the risk of disease outbreaks by a combination of behaviors (social immunity) and individual immune function. There is a relationship between the effectiveness of social and individual immunity and the nutritional state of the colony. Parasitic Varroa mites undermine the relationship because they reduce nutrient levels, suppress individual immune function and transmit viruses. Future research directions to better understand the dynamics of the nutrition-immunity relationship based on levels of stress, time of year and colony demographics are discussed. PMID- 29588006 TI - Effects of genotype, environment, and their interactions on honey bee health in Europe. AB - There are several reports of honey bee populations in Europe which survive without treatment for Varroa. However, when evaluated outside their native area, higher survival and resistance traits were not observed in colonies of a survivor population. Varroa infestation is strongly influenced by environmental factors, probably affecting threshold levels on a European scale. In a Europe-wide experiment colonies of local origin survived significantly longer than colonies of non-local origin, clearly indicating the presence of genotype-environment interactions. Transmission by Varroa selects for virulent strains of DWV, but it is currently unknown how these may interact with different genotypes of bees. The distribution of Nosema ceranae is significantly affected by environment, but there is at least one Nosema-resistant population. PMID- 29588007 TI - Overwintering honey bees: biology and management. AB - In temperate climates, honey bees (Apis mellifera) survive the winter by entering a distinct physiological and behavioral state. In recent years, beekeepers are reporting unsustainably high colony losses during the winter, which have been linked to parasitization by Varroa mites, virus infections, geographic location, and variation across honey bee genotypes. Here, we review literature on environmental, physiological, and social factors regulating entrance, maintenance, and exit from the overwintering state in honey bees in temperate regions and develop a testable model to explain how multiple factors may be acting synergistically to regulate this complex transition. We also review existing knowledge of the factors affecting overwintering survival in honey bees and providing suggestions to beekeepers aiming to improve their colonies' overwintering success. PMID- 29588008 TI - Effects of 'inactive' ingredients on bees. AB - Honey bees are sensitive to widespread co-formulants used in agrochemicals, and evaluation of the role of these 'inerts or inactives' in pollinator decline is only in its formative stages. Lack of disclosure of formulation ingredients in major products and lack of adequate methods for their analysis constrain the assessment of total chemical load and agrochemical exposures on bees. Most studies to document pesticide effects on honey bees are performed without the formulation or other relevant spray adjuvant components used to environmentally apply the toxicant. Formulations are generally more toxic than active ingredients, particularly fungicides, by up to 26,000-fold based on published literature. Some 'inactive' candidates for future risk assessment for pollinators include the organosilicone surfactants and the co-solvent N-methyl-2-pyrrolidone. PMID- 29588009 TI - Editorial overview: Vectors and medical and veterinary entomology: From molecular biology to field ecology. PMID- 29588010 TI - Integrated pest and pollinator management-adding a new dimension to an accepted paradigm. AB - In this chapter we argue that while pesticides can be harmful to pollinators, when they are used in an integrated pest and pollinator management (IPPM) context, both pest management and pollinator protection may be achieved. Our growing knowledge of the impacts of pesticides on honey bees as well as bumble bees and solitary bees allows us to use the latitude we have in pest management including non-pesticidal pest management practices, changing pesticide types and incorporating other, less susceptible pollinator species into commercial practice. Pollinator health should be a central component of integrated pest management research, education and extension to produce viable IPPM approaches. PMID- 29588011 TI - Molecular pathogenesis of American Foulbrood: how Paenibacillus larvae kills honey bee larvae. AB - American Foulbrood caused by Paenibacillus larvae is one of the unsolved health problems honey bee colonies are suffering from. In the recent past, considerable progress has been achieved in understanding molecular details of P. larvae infections of honey bee larvae. This was facilitated by the development of molecular tools for manipulating P. larvae and by the availability of complete genome sequences of different P. larvae genotypes. We here report on several peptides and proteins that have recently been identified, biochemically analyzed, and proposed to act as virulence factors of P. larvae. For some of them, experimental proof for their role as virulence factor has been provided allowing presenting a preliminary model for the molecular pathogenesis of American Foulbrood. PMID- 29588012 TI - Honey bee surveillance: a tool for understanding and improving honey bee health. AB - Honey bee surveillance systems are increasingly used to characterize honey bee health and disease burdens of bees in different regions and/or over time. In addition to quantifying disease prevalence, surveillance systems can identify risk factors associated with colony morbidity and mortality. Surveillance systems are often observational, and prove particularly useful when searching for risk factors in real world complex systems. We review recent examples of surveillance systems with particular emphasis on how these efforts have helped increase our understanding of honey bee health. PMID- 29588013 TI - Death of the bee hive: understanding the failure of an insect society. AB - Since 2007 honey bee colony failure rates overwinter have averaged about 30% across much of North America. In addition, cases of extremely rapid colony failure have been reported, which has been termed colony collapse disorder. Both phenomena result from an increase in the frequency and intensity of chronic diseases and environmental stressors. Colonies are often challenged by multiple stressors, which can interact: for example, pesticides can enhance disease transmission in colonies. Colonies may be particularly vulnerable to sublethal effects of pathogens and pesticides since colony functions are compromised whether a stressor kills workers, or causes them to fail at foraging. Modelling provides a way to understand the processes of colony failure by relating impacts of stressors to colony-level functions. PMID- 29588014 TI - Xenobiotic detoxification pathways in honey bees. AB - Relative to most other insect genomes, the western honey bee Apis mellifera has a deficit of detoxification genes spanning Phase I (functionalization), II (conjugation) and III (excretion) gene families. Although honeybees do not display across-the-board greater sensitivity to pesticides, this deficit may render them vulnerable to synergistic interactions among xenobiotics. Diet quality, in terms of protein and phytochemical content, has a pronounced influence on tolerance of toxic compounds. Detoxification gene inventory reduction may reflect an evolutionary history of consuming relatively chemically benign nectar and pollen, as other apoid pollinators display comparable levels of cytochrome P450 gene reduction. Enzymatic detoxification in the eusocial A. mellifera may be complemented by behaviors comprising a 'social detoxification system,' including forager discrimination, dilution by pollen mixing, and colony food processing via microbial fermentation, that reduces the number or quantity of ingested chemicals requiring detoxification. PMID- 29588015 TI - Connecting genotypes to medically relevant phenotypes in major vector mosquitoes. AB - Transmission of mosquito-borne human disease relies on vectors maintaining strong human host preference and continued susceptibility to disease-causing pathogens or parasites. These traits are affected by the genetics and the environments of all involved organisms, and genotypic interactions are common between parasite and vector, and between virus and vector. A recent study on Aedes host preference has exploited natural genetic variation to make great progress. Here I review our current understanding of the genetic basis of transmission-relevant traits in Anopheles and Aedes, highlighting additional research areas that would benefit from the integration of natural genetic variation. PMID- 29588016 TI - Chalkbrood: epidemiological perspectives from the host-parasite relationship. AB - Chalkbrood is a fungal brood disease of the honey bee, Apis mellifera, caused by the parasite Ascosphaera apis. Considered as a stress-related disease, the severity of chalkbrood outbreaks depend on a multitude of interacting factors. The specific relationship between host and parasite in this disease is interesting because the parasite is both heterothallic and semelparous. Recent studies highlight that this specific host-parasite relationship is influenced by factors such as interactions with other parasite strains or species, and environmental perturbations. To understand how to protect pollinators most effectively, it is crucial that future research takes a more ecologically relevant approach by studying the basic biology of the host-parasite relationship in the context of the multi-factorial processes that influence it. PMID- 29588017 TI - Intersections between neonicotinoid seed treatments and honey bees. AB - A growing understanding of the often subtle unintended impacts of neonicotinoid seed treatments on both non-target organisms and their environment have led to concerns about the suitability of current pest management approaches in large scale agriculture. Several neonicotinoid compounds are used in seed treatments of the most widely grown grain and oilseed crops worldwide. Most applications are made prophylactically and without prior knowledge of pest populations. A growing body of evidence suggests that these compounds become contaminants of soil, water, and plant products, including pollen and nectar. These unforeseen routes of exposure are documented to have negative impacts on honey bee health and also have potential to exert effects on a broader environmental scale. PMID- 29588018 TI - Chemical ecology and olfaction in arthropod vectors of diseases. AB - Hematophagous arthropods (ticks and insects, collectively hereafter referred to as vectors) transmit various life threatening diseases resulting in over one million human deaths annually. Exploiting vertebrates for blood demanded extensive sensory and behavioral adaptations that are apparent across the evolutionary range of vector species, from primitive ticks to advanced dipterans. Since animal senses are biological features that have been shaped by natural selection to promote adaptive behavior, a variety of exciting patterns are apparent in what they sense and how. Vectors display robust olfactory driven behaviors. A distinct yet limited range of volatile organic compounds are parsimoniously used as major cues for tracking in various contexts. These chemicals elicit behaviors such as attraction or repulsion/avoidance while vectors seek habitats, hosts, mates, or oviposition sites. Interestingly, there is a substantial consilience among olfactory structures and function in arthropod vectors, which is also reflected in the parsimonious use of chemical ligands. A detailed analysis of chemosensory signals and reception by these arthropod vectors can be exploited to identify natural ligands that can be used as baits to manipulate vector behaviors. PMID- 29588019 TI - Genetic technologies for disease vectors. AB - The first genetic technologies for insect vectors of disease were introduced 20 years ago. As of today there are 12 classes of genetic technologies used as functional genomic tools for insect vectors of important diseases. Although the applications of genetic technologies in insect disease vectors have been conducted primarily in mosquitoes, other insect systems could benefit from current technologies. While the various technological platforms are likely to function in diverse arthropods, the delivery of these technologies to cells and tissues of interest is the major technical constraint that limits their widespread adoption. Increased community resources of various types would enhance the adoption of these technologies and potentially eliminate technical limitations. PMID- 29588020 TI - Impact of insect salivary proteins in blood feeding, host immunity, disease, and in the development of biomarkers for vector exposure. AB - Functional genomic approaches based on expression of recombinant proteins linked to biochemical and disease model approaches resulted in the discovery of novel biological activities and the role some of these proteins play in disease transmission. Importantly, the expression of salivary proteins was recently shown to be affected by environmental factors and by the presence of the pathogen in the salivary gland. A practical application resulting from insect saliva research is the use of insect antigenic salivary protein as biomarkers of vector exposure in humans and animal reservoirs, an approach that is yielding interesting results in the field.

PMID- 29588022 TI - Use of whole body vibration in individuals with chronic stroke: Transmissibility and signal purity. AB - This study examined (1) the influence of whole body vibration (WBV) frequency (20 Hz, 30 Hz, 40 Hz), amplitude (low: 0.8 mm and high: 1.5 mm) and body postures (high-squat, deep-squat, tip-toe standing) on WBV transmissibility and signal purity, and (2) the relationship between stroke motor impairment and WBV transmissibility/signal purity. Thirty-four participants with chronic stroke were tested under 18 different conditions with unique combinations of WBV frequency, amplitude, and body posture. Lower limb motor function and muscle spasticity were assessed using the Fugl-Meyer Assessment and Modified Ashworth Scale respectively. Nine tri-axial accelerometers were used to measure acceleration at the WBV platform, and the head, third lumbar vertebra, and bilateral hips, knees, and ankles. The results indicated that WBV amplitude, frequency, body postures and their interactions significantly influenced the vibration transmissibility and signal purity among people with chronic stroke. In all anatomical landmarks except the ankle, the transmissibility decreased with increased frequency, increased amplitude or increased knee flexion angle. The transmissibility was similar between the paretic and non-paretic side, except at the ankle during tip toe standing. Less severe lower limb motor impairment was associated with greater transmissibility at the paretic ankle, knee and hip in certain WBV conditions. Leg muscle spasticity was not significantly related to WBV transmissibility. In clinical practice, WBV amplitude, frequency, body postures need to be considered regarding the therapeutic purpose. Good contact between the feet and vibration platform and symmetrical body-weight distribution pattern should be ensured. PMID- 29588023 TI - Managing soft tissues in severe lower limb trauma in an ageing population. AB - PURPOSE: With an ageing population, the incidence of trauma in those aged over 65 years is increasing. Strategies for dealing with these patients must be developed. At present the standard management of open tibial fractures in the UK is described by the BOAST4 guidelines (from the British Orthopaedic Association and British Association of Plastic & Aesthetic Surgeons). It is not clear to what extent these are appropriate for older patients. We describe our experience of managing elderly patients presenting with open tibial fractures. METHOD: Patients were identified via prospectively collected national and departmental databases. These data were supplemented by review of the patient records and radiographs. Data collated included patient demographics, injury details, orthopaedic and plastic surgery operative details, and long-term outcomes. RESULTS: Between January 2013 and June 2016, 74 patients aged over 65 years were admitted with open lower limb fractures. 54 of these were open tibial fractures and these patients formed the study group. 19 patients required soft-tissue reconstruction for Gustilo and Anderson IIIB tibial fractures (age range, 67-95 years). In these patients, there were 7 midshaft (AO 42), 1 proximal (AO 41), and 11 distal (AO 43) fractures. 13 patients were treated with internal fixation and 6 with circular frames. The median length of hospital stay was 27 days (range, 4-85). 14 patients received loco-regional flaps and 5 underwent free tissue transfer with one requiring preoperative femoral angioplasty. There were no flap losses. Four patients had fasciocutaneous flaps, 3 tibialis anterior transposition, 2 an extensor digitorum brevis flap, 1 a hemisoleus flap, and 4 were skin grafted. All patients went on to unite and return to their premorbid weight-bearing status (4 using walking frames, 3 using sticks, and 12 walking independently). CONCLUSION: Although the literature suggests a significantly higher complication rate in elderly patients with open fractures, we have demonstrated comparable rates of flap survival and bony union to those observed in younger patients. Challenges are presented in terms of patient physiology and these must be carefully managed pre- and postoperatively. These challenges are reflected in prolonged hospital stays. PMID- 29588024 TI - Effect of high frequency electromagnetic wave stimulation on muscle injury in a rat model. AB - INTRODUCTION: The aim of this study was to investigate biological changes in tissues with muscle contusion after the application of high frequency (HF) electromagnetic wave. METHODS: An acrylic pipe was placed on the right hind limb and a metallic ball was dropped inside the pipe, which resulted in a muscle contusion. After acquiring the optimal condition for muscle contusion, 20 Sprague Dawley rats were allocated to the HF treatment (N = 10) and sham groups (N = 10), which then underwent muscle contusion injury at their right thigh. The thickness and circumference of the right thigh and the left thigh (negative control groups) were measured (day 0). HF electromagnetic wave stimulation for three days was performed on the contusion area in the HF group after one day. Thickness was measured at the thickest area of both hind limbs and the circumference was measured every day for three days. The sham group received no treatment, and the circumference and thickness were measured using the same method. After three days, Hematoxylin and eosin and immunohistochemical (IHC) staining for IL-1beta were performed and TUNEL assay was conducted for apoptosis in the skin and muscle layers. RESULTS: The thigh muscle thickness at day 1 was significantly different between groups (P = 0.018) and this difference was observed between both sham and control groups (corrected P = 0.007), and between sham and HF groups (corrected P = 0.043). Thigh circumference was significantly different at day 3 (P = 0.047) and this difference was found between sham and control groups (corrected P = 0.018), and between sham and HF groups (corrected P = 0.032). In the HF group, the inflammatory response was reduced to almost the same level as the control group. Evaluation of IL-1beta level, the inflammatory cytokine, through IHC showed marked localization of IL-1beta in muscle fibers of the sham group. However, significantly less IL-1beta was observed in the muscle of the HF treatment group. There was neither injury nor apoptosis after HF stimulation. CONCLUSIONS: Application of the HF showed therapeutic effect on muscle contusion by reducing muscle swelling. This effect might be caused by the anti-inflammatory action of the HF, which evoked energy into the injured muscle. PMID- 29588025 TI - General Genetic Strategies. AB - It is difficult to study the genetics and molecular mechanisms of anesthesia in humans. Fortunately, the genetic approaches in model organisms can, and have, led to profound insights as to the targets of anesthetics. In turn, the organization of these putative targets into meaningful pathways has begun to elucidate the mechanisms of action of these agents. However, it is important to first appreciate the strengths, and limitations, of genetic approaches to understand the anesthetic action. Here we compare the commonly used genetic model organisms, various anesthetic endpoints, and different modes of genetic screens. Coupled with the more specific data presented in subsequent chapters, this chapter places those results in a framework with which to analyze the discoveries across organisms and eventually extend the resulting models to humans. PMID- 29588026 TI - Approaches to Anesthetic Mechanisms: The C. elegans Model. AB - Understanding the mechanisms of volatile anesthetics has been a complex problem that has intrigued investigators for decades. Through the use of relatively simple model organisms-including the nematode Caenorhabditis elegans-progress has been made. Like any model system, C. elegans has both advantages and disadvantages, which are discussed in this chapter. Methods are provided for exposing worms to volatile anesthetics in airtight glass chambers, and for measuring the concentrations of anesthetic in the chambers by gas chromatography. In addition, various behavioral assays are described for characterizing the worms' responses to anesthetics. C. elegans identified proteins that play a role in anesthetic sensitivity that are highly conserved in other organisms, including humans. With precisely characterized neural development, C. elegans has also afforded an excellent opportunity to study anesthetic-induced neurotoxicity. Continued progress in understanding anesthetic action is anticipated from the ongoing study of C. elegans and other animal models. PMID- 29588027 TI - Using Drosophila to Understand General Anesthesia: From Synapses to Behavior. AB - Investigating mechanisms of general anesthesia requires access to multiple levels of neuronal function, from effects at individual synapses to responses in behaving animals. Drosophila melanogaster provides an excellent model to test different theories for general anesthesia because it offers robust methods for testing local as well as global target processes, in an animal that is similarly impacted by these diverse drugs as humans. Here, we outline methods to quantify two such endpoints, neurotransmission and behavioral responsiveness, focusing on the intravenous drug propofol. PMID- 29588028 TI - High-Throughput Screening to Identify Anesthetic Ligands Using Xenopus laevis Tadpoles. AB - General anesthetics are considered among the most significant advances in modern medicine; however, they are also some of the most dangerous commonly administered drugs. Despite this, the discovery of novel anesthetics has been slow, with few clinically used agents regardless of their nearly 200-year history. Xenopus laevis frogs have a long history as a model organism and provide a vital bridge between in vitro and preclinical mammalian assays. The provided protocols are efficient and cost-effective and therefore readily amendable for high-throughput evaluation of novel anesthetic ligands. By using the X. laevis bioassay, a researcher is capable of determining relative general anesthetic tolerance and/or cross-tolerance for candidate nonvolatile and/or volatile ligands. PMID- 29588029 TI - Zebrafish: A Pharmacogenetic Model for Anesthesia. AB - General anesthetics are small molecules that interact with and effect the function of many different proteins to promote loss of consciousness, amnesia, and sometimes, analgesia. Owing to the complexity of this state transition and the transient nature of these drug/protein interactions, anesthetics can be difficult to study. The zebrafish is an emerging model for the discovery of both new genes required for the response to and side effects of anesthesia. Here we discuss the tools available to manipulate the zebrafish genome, including both genetic screens and genome engineering approaches. Additionally, there are various robust behavior assays available to study anesthetic and other drug responses. These assays are available for single-gene study or high throughput for genetic or drug discovery. Finally, we present a case study of using propofol as an anesthetic in the zebrafish. These techniques and protocols make the zebrafish a powerful model to study anesthetic mechanisms and drug discovery. PMID- 29588030 TI - The Mouse as a Model Organism for Assessing Anesthetic Sensitivity. AB - The mouse has been used in many medical fields as a powerful model to reveal the genetic basis of human physiology and disease. The past two decades have witnessed an enormous wealth of genetic and informatic resources dedicated to this humble organism. With the ongoing revolution in mapping neural circuitry governing behavior, the mouse is an ideal model organism poised to unravel the mysteries of general anesthetic action. This chapter will describe and provide guidelines for anesthetic phenotyping in the mouse including both motor-dependent and motor-independent assessments. PMID- 29588031 TI - Identification of General Anesthetic Target Protein-Binding Sites by Photoaffinity Labeling and Mass Spectrometry. AB - General anesthetics are unique in that they represent a diverse range of chemical structures. Therefore, it is not surprising that the desired and undesired molecular targets, and binding sites therein, are as equally diverse and unique. Photoaffinity labeling has proven to be a valuable strategy for the identification of anesthetic molecular targets, as well as binding sites within those targets. In combination with the advances in mass spectrometry-based proteomics, along with the ability to comprehensively map posttranslational modifications, the method is likely to undergo continued improvement. Here, we provide the fundamentals for the design and development of an anesthetic photolabel. We also outline a protocol for the identification of photolabeled residues by mass spectrometry. The major steps include the photolabeling experiment, sample preparation, high-resolution mass spectrometry, and data analysis. The protocol can be used as a foundation for further optimization for the specific protein of interest and conditions of an experiment. The use of photoaffinity labeling adds an advantageous alternative and/or complementary approach to increase understanding of anesthetic molecular mechanisms. PMID- 29588032 TI - Xenon-Protein Interactions: Characterization by X-Ray Crystallography and Hyper CEST NMR. AB - The physiological activity of xenon has long been recognized, though the exact nature of its interactions with biomolecules remains poorly understood. Xe is an inert noble gas, but can act as a general anesthetic, most likely by binding internal hydrophobic cavities within proteins. Understanding Xe-protein interactions, therefore, can provide crucial insight regarding the mechanism of Xe anesthesia and potentially other general anesthetic agents. Historically, Xe protein interactions have been studied primarily through X-ray crystallography and nuclear magnetic resonance (NMR). In this chapter, we first describe our methods for preparing Xe derivatives of protein crystals and identifying Xe binding sites. Second, we detail our procedure for 129Xe hyper-CEST NMR spectroscopy, a versatile NMR technique well suited for characterizing the weak, transient nature of Xe-protein interactions. PMID- 29588033 TI - Computational Approaches to Studying Voltage-Gated Ion Channel Modulation by General Anesthetics. AB - Voltage-gated ion channels (VGICs) are responsible for the propagation of electrical signals in excitable cells. Small-molecule modulation of VGICs affects transmission of action potentials in neurons and thus can modulate the activity of the central nervous system. For this reason, VGICs are considered key players in the medically induced state of general anesthesia. Consistently, VGICs have been shown to respond to several general anesthetics. However, in spite of extensive electrophysiological characterizations, modulation of VGICs by anesthetics is still only partially understood. Among the challenging aspects are the presence of multiple binding sites and the observation of paradoxical effects, i.e., evidence, for the same channel, of inhibition and potentiation. In this context, molecular simulations emerged in the recent past as the tool of choice to complement electrophysiology studies with a microscopic picture of binding and allosteric regulation. In this chapter, we describe the most effective computational techniques to study VGIC modulation by general anesthetics. We start by reviewing the VGIC conduction cycle, the corresponding set of channel conformations, and the approaches used to model them. We then review the most successful strategies to identify binding sites and estimate binding affinities. PMID- 29588034 TI - Methods for Defining the Neuroprotective Properties of Xenon. AB - Xenon has features that make it an ideal general anesthetic agent; cost and scarcity mitigate xenon's widespread use in the operating room. Discovery of xenon's cytoprotective properties resulted in its application to thwart ongoing acute neurologic injury, an unmet clinical need. The discovery that xenon's neuroprotective effect interacts synergistically with targeted temperature management (TTM) led to its investigation in clinical settings, including in the management of the postcardiac arrest syndrome, in which TTM is indicated. Following successful demonstration of xenon's efficacy in combination with TTM in a preclinical model of porcine cardiac arrest, xenon plus TTM was shown to significantly decrease an imaging biomarker of brain injury for out of hospital cardiac arrest victims that had been successfully resuscitated. With the development of an efficient delivery system the stage is now set to investigate whether xenon improves survival, with good clinical outcome, for successfully resuscitated victims of a cardiac arrest. PMID- 29588035 TI - Xenon Anesthesia and CT: Noninvasive Measures of Brain Anesthetic Concentration. AB - The existence of a barrier between anesthetic behavioral state transitions has been observed across phyla, but demonstrating that such a barrier exists and is not a pharmacokinetic artifact has not yet been possible in humans. Such an investigation requires temporally precise information regarding the brain concentration of anesthetic in order to demonstrate the specific pharmacokinetic pharmacodynamic mismatch that is hysteresis. We propose a method to noninvasively determine brain tissue anesthetic concentration using computerized tomography and the radiopaque gaseous anesthetic xenon. Such a technique can be used to investigate pharmacokinetic-pharmacodynamic mismatches in humans. PMID- 29588036 TI - Physical Accuracy Leads to Biological Relevance: Best Practices For Simulating Ligand-Gated Ion Channels Interacting With General Anesthetics. AB - Efforts to detect binding modes of general anesthetics (GAs) for pentameric ligand-gated ion channels (pLGICs) are often complicated by a large number of indicated sites, as well as the challenges of ranking sites by affinity and determining which sites are occupied at clinical concentrations. Physics-based computational methods offer a powerful route for determining affinities of ligands to isolated binding sites, but preserving accuracy is essential. This chapter describes a step-by-step approach to multiple methods for identifying candidate sites and quantifying binding affinities and also discusses limitations and common pitfalls. PMID- 29588037 TI - Native System and Cultured Cell Electrophysiology for Investigating Anesthetic Mechanisms. AB - Anesthetic agents interact with a variety of ion channels and membrane-bound receptors, often at agent-specific binding sites of a single protein. These molecular-level interactions are ultimately responsible for producing the clinically anesthetized state. Between these two scales of effect, anesthetic agents can be studied in terms of how they impact the physiology of neuronal circuits, individual neurons, and cells expressing individual receptor types. The acutely dissected hippocampal slice is one of the most extensively studied and characterized preparations of intact neural tissue and serves as a highly useful experimental model system to test hypotheses of anesthetic mechanisms. Specific agent-receptor interactions and their effect on excitable membranes can further be defined with molecular precision in cell-based expression systems. We highlight several approaches in these respective systems that we have used and that also have been used by many investigators worldwide. We emphasize economy and quality control, to allow an experimenter to carry out these types of studies in a rigorous and efficient manner. PMID- 29588038 TI - Electrophysiological Analysis of Voltage-Gated Ion Channel Modulation by General Anesthetics. AB - Voltage-gated ion channels (VGICs) of excitable tissues are emerging as targets likely involved in both the therapeutic and toxic effects of inhaled and intravenous general anesthetics. Whereas sevoflurane and propofol inhibit voltage gated Na+ channels (Navs), sevoflurane potentiates certain voltage-gated K+ channels (Kvs). The combination of these effects would dampen neural excitability and, therefore, might contribute to the clinical endpoints of general anesthesia. As the body of work regarding the interaction of general anesthetics with VGICs continues to grow, a multidisciplinary approach involving functional, biochemical, structural, and computational techniques, many of which are detailed in other chapters, has increasingly become necessary to solve the molecular mechanism of general anesthetic action on VGICs. Here, we focus on electrophysiological and modeling approaches and methodologies to describe how our work has elucidated the biophysical basis of the inhibition Navs by propofol and the potentiation of Kvs by sevoflurane. PMID- 29588040 TI - HCN and K2P Channels in Anesthetic Mechanisms Research. AB - The ability of a diverse group of agents to produce general anesthesia has long been an area of intense speculation and investigation. Over the past century, we have seen a paradigm shift from proposing that the anesthetized state arises from nonspecific interaction of anesthetics with the lipid membrane to the recognition that the function of distinct, and identifiable, membrane-embedded proteins is dramatically altered in the presence of intravenous and inhaled agents. Among proteinaceous targets, metabotropic and ionotropic receptors garnered much of the attention over the last 30 years, and it is only relatively recently that voltage gated ion channels have clearly and rigorously been shown to be important molecular targets. In this review, we will consider the experimental issues relevant to two important ion channel anesthetic targets, HCN and K2P. PMID- 29588039 TI - Combining Mutations and Electrophysiology to Map Anesthetic Sites on Ligand-Gated Ion Channels. AB - General anesthetics are known to act in part by binding to and altering the function of pentameric ligand-gated ion channels such as nicotinic acetylcholine and gamma-aminobutyric acid type A receptors. Combining heterologous expression of the subunits that assemble to form these ion channels, mutagenesis techniques and voltage-clamp electrophysiology have enabled a variety of "structure function" approaches to questions of where anesthetic binds to these ion channels and how they enhance or inhibit channel function. Here, we review the evolution of concepts and experimental strategies during the last three decades, since molecular biological and electrophysiological tools became widely used. Topics covered include: (1) structural models as interpretive frameworks, (2) various electrophysiological approaches and their limitations, (3) Monod-Wyman-Changeux allosteric models as functional frameworks, (4) structural strategies including chimeras and point mutations, and (5) methods based on cysteine substitution and covalent modification. We discuss in particular depth the experimental design considerations for substituted cysteine modification-protection studies. PMID- 29588041 TI - Molecular Mechanics Parameterization of Anesthetic Molecules. AB - Anesthetic drug molecules are being increasingly studied through the use of computational methods such as molecular dynamics (MD). Molecular mechanics force fields require the investigator to supply parameters for the force field equation, which are not available for novel molecules. Careful selection of these parameters is critical for simulations to produce meaningful results. Therefore, this chapter presents a state-of-the-art method for determining these parameters by comparison to quantum mechanics calculations and experimental quantities. Ketamine is used as an example to demonstrate the process. PMID- 29588042 TI - Insights Into Receptor-Based Anesthetic Pharmacophores and Anesthetic-Protein Interactions. AB - General anesthetics are thought to allosterically bind and potentiate the inhibitory currents of the GABAA receptor through drug-specific binding sites. The physiologically relevant isoform of the GABAA receptor is a transmembrane ligand-gated ion channel consisting of five subunits (gamma-alpha-beta-alpha-beta linkage) symmetrically arranged around a central chloride-conducting pore. Although the exact molecular structure of this heteropentameric GABAA receptor remains unknown, molecular modeling has allowed significant advancements in understanding anesthetic binding and action. Using the open-channel conformations of the homologous glycine and glutamate-gated chloride receptors as templates, a homology model of the GABAA receptor was constructed using the Discovery Studio computational chemistry software suite. Consensus structural alignment of the homology templates allowed for the construction of a three-dimensional heteropentameric GABAA receptor model with (gamma2-beta3-alpha1-beta3-alpha1) subunit linkage. An anesthetic binding site was identified within the transmembrane alpha/beta intersubunit space by the convergence of three residues shown to be essential for anesthetic activity in previous studies with mutant mice (beta3-N265, beta3-M286, alpha1-L232). Propofol derivatives docked into this binding site showed log-linear correlation with experimentally derived GABAA receptor potentiation (EC50) values, suggesting this binding site may be important for receptor activation. The receptor-based pharmacophore was analyzed with surface maps displaying the predominant anesthetic-protein interactions, revealing an amphiphilic binding cavity incorporating the three residues involved in anesthetic modulation. Quantum mechanics calculations of the bonding patterns found in complementary high-resolution receptor systems further elucidated the complex nature of anesthetic-protein interactions. PMID- 29588043 TI - Understanding Anesthetic Mechanisms: Analysis of the Complex Kinetics of Ligand Gated Ion Channels. AB - Anesthetics modulate the response of ligand-gated ion channels to their neurotransmitter agonists, in a way that is consistent with clinical anesthesia: inhibition of synaptic transmission, by activation of inhibitory receptors and/or inhibition of excitatory receptors. Electrophysiological results for receptors such as GABAAR indicate that this modulation can be remarkably kinetically complex, characterized by concentration-dependent changes in the extent and (multiple) time scales of desensitization and deactivation. The full range of these features cannot be reproduced by a kinetic model in which anesthetic acts only by binding to putative protein sites, without having multiple sites with varying affinities, as well as many additional conformational states beyond the canonical set of three (resting, open, and desensitized). So, we discuss the implementation of a kinetic approach that incorporates only these three states, but accounts for effects of adsorption of anesthetic and agonist to the membrane in which the receptor is embedded, which modulates the conformational free energy landscape of the protein. As a result, the rate constants of conformational transitions become time dependent (non-Markovian), requiring nonstandard methods of kinetic analysis that can readily be implemented using available computational software.

AB - Tragically, investigations have shown many cases of teachers in private schools sexually abusing students.1 Most cases occurred from the 1960s through the 1990s and involved eccentric, creative, highly valued, and long-serving teachers. Some were indiscriminate predators who abused many children, others abused one or a few students, and some "groomed" students by developing a special emotional relationship during high school and then initiating a sexual relationship after graduation. Often, abusers and victims were vulnerable because of low self esteem, depression, divorce, or substance use. Most of the abuse concerned a male teacher and a female student, but some concerned same-sex teacher and student or a female teacher and a male student. PMID- 29588046 TI - Meta-Analyses in Child and Adolescent Psychiatry: Getting Closer to Clinical Practice. AB - Rigorously conducted meta-analyses provide evidence synthesis that has the potential to inform daily clinical decision making and development of clinical guidelines. In the past decade, there has been an increasing number of studies on pharmacologic and non-pharmacologic treatments for childhood and adolescent psychiatric disorders. Given this large body of research, busy clinicians might tend to rely on meta-analyses, rather than individual trials, to keep abreast of the evidence base supporting intervention strategies in child and adolescent psychiatry. Many meta-analyses focused on treatments for child and adolescent mental health problems have primarily addressed the question: Is treatment X more efficacious/effective (or safer) than the control condition? This is clearly an important starting point for clinicians when discussing with their patients and families the benefits and risks of treatment X, but clinicians need to know more. For instance, they might look for the evidence base to answer the following questions: Is treatment X the most efficacious and effective (or safest) option for my patient? When will treatment X likely start working? If the dose or intensity of the treatment does not seem to be effective, is it worthwhile to increase it? And if so, how? PMID- 29588047 TI - Promoting Success Across School Years for Children With Attention Deficit/Hyperactivity Disorder: Collaborative School-Home Intervention. AB - Children with attention-deficit/hyperactivity disorder (ADHD) typically experience significant difficulties in school, including academic underachievement and impairment in social relationships, such that they are at higher than average risk for special education placement, grade retention, school dropout, and lower lifetime educational attainment.1 The chronicity of ADHD symptoms and associated impairments requires proactive maintenance of treatment components across school years if amelioration of deleterious long-term outcomes is to be realized. Pfiffner et al.2 directly address the ongoing school impairments experienced by students with ADHD by following intensive intervention in 1 school year with booster treatment in a subsequent school year. The Collaborative Life Skills (CLS) program includes multiple components initially delivered over 10 to 12 weeks to train teachers in use of classroom accommodations and strategies (e.g., daily report card), parents in use of behavioral strategies at home and ways to collaborate with teachers, and children in social skills and independent task completion. PMID- 29588048 TI - "Communities" of Conditions: Novel Methods for Classifying Psychiatric Disorders. AB - In 1798, Philippe Pinel presented one of the first nosologies for psychiatric disorders, "Nosographie philosophique ou la methode de l'analyse appliquee a la medecine."1 His emphasis on psychological and physical conditions as the basis of mental illness provided a distinct departure from prior reliance on such etiologies such as demonic possession. Establishing classification schema was a much more profound innovation than a simple academic reordering of psychiatric phenomena-under Pinel's leadership at the famed Pitie-Salpetriere hospital, it also led to a radical reformation of clinical interventions, moving away from pseudoscientific practices toward psychologically based interventions. Much of this work influenced his successors in psychiatric taxonomy including Emil Kraeplin and others, ultimately forming the basis of the DSM.2 Although the DSM has been subsequently celebrated and maligned, it has been instrumental in both our conceptualization and treatment approach to psychiatric disorders. Indeed, there has been extensive effort to validate these conditions using factor analytic approaches to confirm that such conditions represent cohesive biologically based disorders, which has presented challenges.3. PMID- 29588050 TI - Sustained Effects of Collaborative School-Home Intervention for Attention Deficit/Hyperactivity Disorder Symptoms and Impairment. AB - OBJECTIVES: The Collaborative Life Skills (CLS) program is a school-home intervention for students with attention-deficit/hyperactivity disorder (ADHD) symptoms and impairment. CLS integrates school, parent, and student treatments followed by booster sessions during a maintenance period into the subsequent school year. The program is delivered by school-based mental health providers. Beneficial post-treatment effects have been documented. This study evaluated the effects of CLS after the maintenance period in the subsequent school year. METHOD: Using a cluster randomized design, schools within a large urban public school district were randomly assigned to CLS (12 schools) or usual services (11 schools). Approximately 6 students participated at each school (N = 135, grade range = 2-5). Measures were completed at baseline, after treatment, and follow-up during the next school year. RESULTS: Students from schools assigned to CLS compared with those assigned to usual services showed significantly greater improvement at follow-up on parent, but not teacher, ratings of ADHD and oppositional defiant disorder symptom severity, organizational skills, and global impairment. Within-group analyses indicated that parent- and teacher-reported post-treatment gains for CLS in ADHD and oppositional defiant disorder symptoms, organizational skills, and academic competence were maintained into the next school year. CONCLUSIONS: These results extend support for CLS to the following school year by demonstrating sustained benefits on parent-reported ADHD and oppositional defiant disorder symptoms and functional impairment. The lack of significant teacher-reported differences between CLS and usual services highlights the need for further study of booster treatments for improving outcomes with new teachers across school years.

PMID- 29588049 TI - The Impact of Antidepressant Dose and Class on Treatment Response in Pediatric Anxiety Disorders: A Meta-Analysis. AB - OBJECTIVE: To determine the trajectory and magnitude of antidepressant response as well as the effect of antidepressant class and dose on symptomatic improvement in pediatric anxiety disorders. METHOD: Weekly symptom severity data were extracted from randomized, parallel group, placebo-controlled trials of selective serotonin reuptake inhibitors (SSRIs) and selective serotonin-norepinephrine reuptake inhibitors (SNRIs) in pediatric anxiety disorders. Treatment response was modeled for the standardized change in continuous measures of anxiety using Bayesian updating. Posterior distributions for each study served as informative conjugate prior to distributions update subsequent study posteriors. Change in symptom severity was evaluated as a function of time, class and, for SSRIs, standardized dose. RESULTS: Data from 9 trials (SSRIs: n = 5; SNRIs, n = 4) evaluating 7 medications in 1,673 youth were included. In the logarithmic model of treatment response, statistically, but not clinically, significant treatment effects emerged within 2 weeks of beginning treatment (standardized medication placebo difference = -0.054, credible interval [CI] = -0.076 to -0.032, p = .005, approximate Cohen's d <= 0.2) and by week 6, clinically significant differences emerged (standardized medication-placebo difference = -0.120, CI = -0.142 to 0.097, p = .001, approximate Cohen's d = 0.44). Compared to SNRIs, SSRIs resulted in significantly greater improvement by the second week of treatment (p = .0268), and this advantage remained statistically significant through week 12 (all p values <.03). Improvement occurred earlier with high-dose SSRI treatment (week 2, p = .002) compared to low-dose treatment (week 10, p = .025), but SSRI dose did not have an impact on overall response trajectory (p > .18 for weeks 1-12). CONCLUSIONS: In pediatric patients with generalized, separation, and/or social anxiety disorders, antidepressant-related improvement occurred early in the course of treatment, and SSRIs were associated with more rapid and greater improvement compared to SNRIs. PMID- 29588051 TI - Data-Driven Subtyping of Executive Function-Related Behavioral Problems in Children. AB - OBJECTIVE: Executive functions (EF) are cognitive skills that are important for regulating behavior and for achieving goals. Executive function deficits are common in children who struggle in school and are associated with multiple neurodevelopmental disorders. However, there is also considerable heterogeneity across children, even within diagnostic categories. This study took a data-driven approach to identify distinct clusters of children with common profiles of EF related difficulties, and then identified patterns of brain organization that distinguish these data-driven groups. METHOD: The sample consisted of 442 children identified by health and educational professionals as having difficulties in attention, learning, and/or memory. We applied community clustering, a data-driven clustering algorithm, to group children by similarities on a commonly used rating scale of EF-associated behavioral difficulties, the Conners 3 questionnaire. We then investigated whether the groups identified by the algorithm could be distinguished on white matter connectivity using a structural connectomics approach combined with partial least squares analysis. RESULTS: The data-driven clustering yielded 3 distinct groups of children with symptoms of one of the following: (1) elevated inattention and hyperactivity/impulsivity, and poor EF; (2) learning problems; or (3) aggressive behavior and problems with peer relationships. These groups were associated with significant interindividual variation in white matter connectivity of the prefrontal and anterior cingulate cortices. CONCLUSION: In sum, data-driven classification of EF-related behavioral difficulties identified stable groups of children, provided a good account of interindividual differences, and aligned closely with underlying neurobiological substrates.

AB - OBJECTIVE: Although studies have found that youth exposed to violence are more likely to carry guns than non-exposed youth, this association could be due to common causal factors or other pre-existing differences between individuals. In this study, within-individual change models were used to determine whether juvenile offenders exhibit an increased propensity to carry a firearm after being exposed to gun violence and/or non-gun violence. The advantage of this approach is all time-invariant factors are eliminated as potential confounders. METHOD: A sample of 1,170 racially/ethnically diverse male juvenile offenders was recruited in Arizona and Pennsylvania (14-19 years old at recruitment). Participants were interviewed every 6 months for 3 years followed by 4 annual assessments. The outcome was gun carrying and the primary predictors were exposure to gun violence and non-gun violence. Time-varying covariates included exposure to peers who carried guns, exposure to peers who engaged in other (non-gun) criminal acts, developmental changes in gun carrying, and changes in gun carrying from incarceration or institutionalization. RESULTS: Adolescent offenders were significantly more likely to carry a gun in recall periods after exposure to gun violence, but not after exposure to non-gun violence. Effect of gun violence on carrying was significant throughout adolescence and young adulthood and could not be accounted for by time-varying and time-invariant confounders. CONCLUSIONS: Interventions to decrease illegal gun carrying should target young men in medical and mental health settings who experience or witness gun violence and those living in communities with high rates of gun violence.

AB - OBJECTIVE: College entrance may be a strategically well-placed "point of capture" for detecting late adolescents with suicidal thoughts and behaviors (STB). However, a clear epidemiological picture of STB among incoming college students is lacking. We present the first cross-national data on prevalence as well as socio-demographic and college-related correlates for STB among first-year college students. METHOD: Web-based self-report surveys were obtained from 13,984 first year students (response rate 45.5%) across 19 colleges in 8 countries (Australia, Belgium, Germany, Mexico, Northern Ireland, South Africa, Spain, and the United States). RESULTS: Lifetime prevalence of suicidal ideation, plans, and attempts was 32.7%, 17.5%, and 4.3%, respectively. The 12-month prevalence was 17.2%, 8.8%, and 1.0%, respectively. About three-fourths of STB cases had onset before the age of 16 years (Q3 = 15.8), with persistence figures in the range of 41% to 53%. About one-half (53.4%) of lifetime ideators transitioned to a suicide plan; 22.1% of lifetime planners transitioned to an attempt. Attempts among lifetime ideators without plan were less frequent (3.1%). Significant correlates of lifetime STB were cross-nationally consistent and generally modest in effect size (median adjusted odds ratio [aOR] = 1.7). Nonheterosexual orientation (aOR range 3.3-7.9) and heterosexual orientation with some same-sex attraction (aOR range 1.9-2.3) were the strongest correlates of STB, and of transitioning from ideation to plans and/or attempts (aOR range 1.6-6.1). CONCLUSION: The distribution of STB in first-year students is widespread, and relatively independent of socio demographic risk profile. Multivariate risk algorithms based on a high number of risk factors are indicated to efficiently link high-risk status with effective preventive interventions. PMID- 29588054 TI - Prevalence of Mental Disorder and Service Use by Immigrant Generation and Race/Ethnicity Among U.S. Adolescents. AB - OBJECTIVE: To examine differences in lifetime prevalence of mental disorder and service use among U.S. adolescents by both immigrant generation and race/ethnicity. METHOD: A total of 6,250 adolescents aged 13 to 18 years in the National Comorbidity Survey Replication Adolescent Supplement were assessed for lifetime prevalence of mood and/or anxiety disorders, behavior disorders, and mental health service use. Twelve groups defined by self-identified race/ethnicity (non-Hispanic white, Hispanic, non-Hispanic black, Asian) and immigrant generation (first, second, third, or more) were compared. RESULTS: Differences in prevalence of lifetime mental disorder were most apparent when immigrant generation and race/ethnicity were considered jointly. Compared to third+generation non-Hispanic white adolescents, the odds of mood/anxiety disorder were increased among second-generation Asian (adjusted odds ratio [AOR] = 2.51; 95% CI = 1.22-5.17) and third+generation Hispanic (AOR = 1.28; 95% CI = 1.00-1.63) but reduced among first-generation Asian (AOR = 0.27; 95% CI = 0.10 0.71) and second-generation non-Hispanic white adolescents (AOR = 0.50; 95% CI = 0.30-0.81). The odds of behavior disorder were lower among first-generation Asian (AOR = 0.26; 95% CI = 0.09-0.71) and all generations of non-Hispanic black adolescents (AOR range 0.43-0.55). Adjusting for lifetime disorder, first generation Hispanic and non-Hispanic white adolescents and all generations of non Hispanic black adolescents were less likely to receive mental health services (AOR range 0.24-0.55). CONCLUSIONS: Variation in risk of disorder by immigrant generation and race/ethnicity underscores the importance of considering social, economic, and cultural influences in etiologic and treatment studies of adolescent psychopathology. Lower rates of service use, particularly among first generation immigrant adolescents, highlight the need to identify and address barriers to recognition and treatment of mental disorders among adolescents from immigrant and racial/ethnic minority backgrounds. PMID- 29588055 TI - Mirtazapine and Weight Gain in Avoidant and Restrictive Food Intake Disorder. AB - Avoidant and restrictive food intake disorder (ARFID) is a newly classified disorder in the DSM-5 that describes a pattern of restrictive eating across the lifespan that results in significant weight loss, nutritional deficiency, dependence on enteral feeding or nutritional supplements, or marked interference in psychosocial functioning.1 Currently, there are no evidence-based treatment approaches or medications for this disorder.2 We have administered a range of psychoactive medications to those with ARFID in our treatment program in an attempt to find an effective medication. One medication of interest has been mirtazapine because it promotes appetite and weight gain, decreases nausea and vomiting, and improves gastric emptying. Although mirtazapine is an off-label approach in a pediatric population and carries a black box warning for an increased risk of suicide, it is an effective treatment for depression and anxiety symptoms in adults and is generally well tolerated.3,4 There are no studies to date reporting on the use of mirtazapine in patients with ARFID.

AB - In order to fight against blindness in the central region of Togo, a project was implemented in a partnership between the Ministry of Health and an international Non-Governmental Organization: the Swiss Red Cross. Cataract surgery underwent an annual audit of the research-action type, in order to improve the functional results of patients. One of the recommendations of these audits was the introduction of manual small incision surgery in place of the classic extracapsular technique. This study had for its objective to evaluate the functional results and follow-up of patients undergoing the new technique compared with quality standards of cataract surgery according to the World Health Organization. This study was carried out by retrospective analysis of records and operative reports of patients over twenty years of age undergoing manual small incision cataract surgery from June 2012 to June 2015. Out of a total of 1292 patients undergoing cataract surgery in the five districts covered by the project during the same period, 1003 patients met the inclusion criteria (77.63 %). Among the 1003 cases, 504 (50.25 %) were male, while 499 (49.75 %) were female. The overall mean age was 62 years. The cataract was total in 84.65 % of cases and partial in 15.35 % of cases where visual acuities were quantifiable. Postoperative complications were dominated by corneal edema (22 %). On the first postoperative day, the good results (visual acuity>=3/10), the average results (visual acuity between 3/10 and 1/10) and the poor results (visual acuity<1/10) were respectively 41.2 %, 50.60 % and 8.2 % without optical correction, changing to 64.40 %, 28.90 % and 6.70 % after optical correction. Between the first and third week, 855 patients (85 %) were seen again. The good, average and poor results were respectively 61.90 %, 35.70 % and 2.40 % without correction, going to 85.30 %, 12.70 % and 2 % after optical correction. Among the 85.30 % good results, 53 % had a visual acuity>=5/10. Residual ametropias are the main cause of poor functional results and the introduction of biometry can contribute to their improvement. Cataract surgery through a well-controlled manual small incision is a promising alternative to the technique of choice, phacoemulsification, which is not yet widely accessible in our low-income countries. PMID- 29588059 TI - Lysophosphatidylinositols, from Cell Membrane Constituents to GPR55 Ligands. AB - Lysophosphatidylinositols (LPIs) are membrane constituents that alter the properties of said membranes. However, recent data showing that the once orphan receptor, GPR55, can act as a receptor for LPIs has sparked a renewed interest in LPIs as bioactive lipids. As evidence supporting the importance of LPIs and/or GPR55 is continuously accumulating and because LPI levels are altered in a number of pathologies such as obesity and cancer, the coming years should bring new, exciting discoveries to this field. In this review, we discuss the recent work on LPIs and on their molecular target, the GPR55 receptor. First, we summarize the metabolism of LPIs before outlining the cellular pathways activated by GPR55. Then, we review the actions of LPIs and GPR55 that could have potential pharmacological or therapeutic applications in several pathophysiological settings, such as cancer, obesity, pain, and inflammation.

PMID- 29588061 TI - Pre-surgical register of tobacco consumption. AB - INTRODUCTION AND OBJECTIVE: Smoking cessation before surgery decreases the risk of complications. The aim of this study was to analyse the smoking register, associated variables and a short talk given to smokers in pre-surgical visits. MATERIAL AND METHOD: Cross-sectional study. The pre-surgical records of 680 patients were assessed. We selected patient sociodemographic variables, surgical intervention characteristics, smoking status and consumption pattern. Logistic regression was used to study the variables association with smoking. RESULTS: A percentage of 97.2 of the pre-surgical records include information on tobacco consumption. Overall 20% of surgical patients are smokers. The probability of smoking is higher among men (adjusted odds ratio [aOR] 2.6, 95% confidence interval [CI] 1.7-4.0) and<=60 years (aOR 5.4, 95% CI 3.2-9.1). None of the records had information regarding a short talk given to patients to give up smoking. CONCLUSION: Smoking consumption was prevalent, but the characterisation of a smoker's profile and short talk given to patient before surgery was practically nonexistent. Ensuring that patients who smokes receives a short talk to give up smoking before surgery is necessary. PMID- 29588062 TI - Impact of aerobic exercise on cognitive impairment and oxidative stress markers in methamphetamine-dependent patients. AB - This study aimed to investigate whether 12-week moderate-intensity aerobic exercise has beneficial effects on oxidative stress markers in blood and on cognitive functions in patients who have methamphetamine dependence. Serum levels of oxidative stress markers, including total anti-oxidation capability, super oxide dismutase (SOD), catalase (CAT), and methane dicarboxylic aldehyde (MDA), were measured at baseline (all participants) and the 12-week follow-up (methamphetamine-dependent patients). Serum levels of CAT and MDA in methamphetamine-dependent patients (n = 68) were higher than those in healthy controls (n = 35) at baseline. Furthermore, the international shopping list (ISL) task scores of methamphetamine-dependent patients were significantly lower than those of the controls, indicating verbal memory deficits in methamphetamine dependent patients. Although there were no significant interactions for all cognitive function scores, aerobic exercise improved the processing speed in methamphetamine-dependent patients. Of interest, aerobic exercise significantly attenuated a spontaneous increase in serum MDA levels in methamphetamine dependent patients after 12-weeks of abstinence. In conclusion, this study showed that methamphetamine-dependent patients with verbal learning and memory deficits have higher serum levels of MDA, and that a 12-week aerobic exercise program may have beneficial effects on the processing speed as well as blood lipid peroxidation in methamphetamine-dependent patients. PMID- 29588063 TI - Evidence for a relatively high proportion of DM2 mutations in a large group of Polish patients. AB - INTRODUCTION: Myotonic dystrophies (DMs) type 1 (DM1) and type 2 (DM2) are autosomal dominant, multisystem disorders, considered the most common dystrophies in adults. DM1 and DM2 are caused by dynamic mutations in the DMPK and CNBP genes, respectively. METHODS: Molecular analyses were performed by PCR and the modified RP-PCR in patients, in their at-risk relatives and prenatal cases. RESULTS: The analysis of Polish controls revealed the range of 5-31 CTG repeats for DM1 and 110-228 bp alleles for DM2. Among 318 confirmed probands - 196 (62%) were DM1 and 122 (38%) - DM2. Within DM1families, 10 subjects carried a low expanded CTG tract (< 100 repeats), which resulted in a full mutation in subsequent generations. Two related individuals had unstable alleles-188 bp and 196 bp without common interruptions. CONCLUSION: The relative frequencies of DM1/DM2 among Polish patients were 68% and 32%, respectively, with a relatively high proportion of DM2 mutations (1.6:1). PMID- 29588064 TI - The evaluation of the effects of steroid treatment on the tumor and peritumoral edema by DWI and MR spectroscopy in brain tumors. AB - OBJECTIVE: To investigate the effects of dexamethasone on brain tumor and peritumoral edema by different sequences of magnetic resonance imaging (MRI). MATERIALS AND METHODS: MRI was performed in 28 patients with brain tumor. Patients were divided into the 3 groups based on the histological diagnosis; Group I: high-grade glial tumor, Group II: low-grade glial tumor, and Group III: brain metastasis. The measurements of peritumoral edema volume and apparent diffusion coefficient (ADC) values were performed while the peak areas of cerebral metabolites were measured by spectroscopy in groups I and II. The changes in edema volumes, ADC values and cholin/creatine peak areas were compared. RESULTS: The volume of peritumoral edema was decreased in groups I and II, but increased in group III after dexamethasone treatment. These changes were not statistically significant for 3 groups. ADC value was decreased in group I and increased in groups II and III. Changes in ADC values were statistically significant. Cholin/creatine peak areas were decreased after dexamethasone in groups I and II, but these changes were also not significant. CONCLUSION: Dexamethasone has no significant effect on the volume of peritumoral edema in glial tumor and metastasis. Moreover, dexamethasone increases the fluid movements in low grade gliomas and metastases, decreases in high grade gliomas. However, more comprehensive clinical studies are needed to show the effects of dexamethasone on brain tumors and peritumoral edema. PMID- 29588065 TI - Atypical Presentation of Escherichia coli Monomicrobial Necrotizing Fasciitis in a Renal Transplant Patient: A Case Report. AB - Skin and soft tissue infections (SSTIs) are one of most frequent infectious causes for referral to the emergency department and one of the most frequent infectious causes of hospital admissions. Escherichia coli, the most commonly occurring gram-negative pathogen involved in these infections, contributes to about 7% of all SSTIs cases where gram-positive organisms reign dominant. Patients are more susceptible to these gram-negative SSTIs if they are neutropenic, have hematologic malignancies, have undergone solid organ or hematopoietic transplantation, or have cirrhotic liver disease. Due to their immunocompromised state, the prognosis is very poor and not well understood. We report a case of an atypical presentation of an E coli monomicrobial necrotizing fasciitis in a renal transplant patient. Our findings support improved mortality with rapid aggressive interventions, such as amputation, in immunocompromised patients. PMID- 29588066 TI - Life-Threatening Everolimus-Associated Pneumonitis: A Case Report and a Review of the Literature. AB - INTRODUCTION: Noninfective pneumonitis is a class-related effect within mammalian target of rapamycin (mTOR) inhibitors, including everolimus, and can occasionally be severe. CASE REPORT: A 62-year-old man, medicated with everolimus due to a heart transplantation 17 years previously and with chronic kidney disease, was admitted to the intensive care unit (ICU) with acute respiratory failure, cardiovascular shock, and impaired renal function requiring dialysis. Computed tomography (CT) scan revealed right upper lobe consolidation. Extensive microbiological workup, autoimmune testing, and cytology were negative and echocardiography showed preserved heart function. Everolimus levels were normal (5.7-6.1 ng/mL) and the drug was suspended at day 9. The patient was difficult to ventilate and responded poorly to broad-spectrum antibiotic and antifungal therapy. On day 25, CT scan and bronchoscopy revealed left-sided alveolar hemorrhage, and corticosteroid pulses were performed. The patient gradually improved. After discharge and 6 months of follow-up, clinical recovery was complete and chest imaging substantially improved. DISCUSSION: Pneumonitis occurs in up to 4.3% of transplant recipients using everolimus for immunosuppression. Despite usually presenting as a mild and self-limited disease, severe cases have been described. Alveolar hemorrhage can occur and is associated with poor outcome. Everolimus levels do not seem to accurately predict toxicity. Corticosteroid therapy has been used with success in severe disease. We review the pathophysiological, clinical, and management-related aspects of this entity with emphasis on its potential severity. CONCLUSION: Our case was a rare occurrence of severe life-threatening pulmonary disease related to everolimus. Awareness of the potential severity of this entity is important for the management of patients using mTOR inhibitors. PMID- 29588067 TI - Particularized trust, generalized trust, and immigrant self-rated health: cross national analysis of World Values Survey. AB - OBJECTIVES: This research examined the associations between two types of trust, generalized and particularized, and self-rated health among immigrants. STUDY DESIGN: Data were drawn from the World Values Survey (WVS6), the latest wave of cross-sectional surveys based on face-to-face interviews. METHODS: The immigrant subsample analyzed herein contains 3108 foreign-born individuals clustered from 51 countries. Given the hierarchically nested data, two-level logistic regressions models were estimated using HLM (Hierarchical Linear Modeling) 7.1. RESULTS: At the individual level, net of socio-economic and demographic factors (age, gender, marital status, education, income, neighborhood security, and subjective well-being), particularized trust was positively related to physical health (odds ratio [OR] = 1.11, P < .001). Generalized trust, however, was not a significant predictor. At the country level, based on alternative models, the aggregate measure of particularized trust was negatively associated with subjective health. The odds of being healthy were on average about 30% lower. CONCLUSION: The interdisciplinary literature on social determinants of health has largely focused on the salubrious impact of trust and other forms of social capital on physical well-being. Many previous studies based on general, not immigrant, populations also did not differentiate between generalized and particularized types of trust. Results from this study suggest that this conceptual distinction is critical in understanding how and to what extent the two are differentially related to immigrant well-being across multiple levels of analysis. PMID- 29588068 TI - Evolving parent-adult child relations: location of multiple children and psychological well-being of older adults in China. AB - OBJECTIVE: This study examines the interplay among intergenerational emotional closeness, location of multiple children, and parental depressive symptoms in the context of massive migration in rural China. STUDY DESIGN: This study is based on a longitudinal survey. METHODS: Longitudinal data were collected from a stratified random sample of age 60 years and older living in rural townships within Chaohu, a primarily agricultural municipal district with massive out migration in China. In 2009, 1224 individuals completed the survey, and 977 (79.8% of the original participants) were followed up in 2012. We estimate fixed effects models to examine how changing collective emotional cohesion and the total composition of children's location affect parents' depressive symptoms. RESULTS: Descriptive analyses show that both the composition of children's location and intergenerational emotional closeness are subject to changes during a 3-year survey interval. Results from fixed-effect models further demonstrate that collective emotional closeness and psychological well-being are positively associated with each other. This association is the strongest when all children are local, but it becomes less prominent when there are more migrant than local children. CONCLUSIONS: This study has provided important evidence that both intergenerational cohesion and location of multiple children evolve over time and jointly influence parents' psychological well-being in later life. The left behind older adults are not necessarily the most vulnerable group in rural China. Those with most adult children living close by could also suffer from a deficit in psychological well-being if the emotional bond between them is weak. PMID- 29588069 TI - Antigen-Specific Tolerization and Targeted Delivery as Therapeutic Strategies for Autoimmune Diseases. AB - The prevalence of autoimmune disorders is increasing steadily and there is no permanent cure available. Immunomodulation through repeated exposure of antigens, known as antigen-specific immune tolerance or antigen-specific immunotherapy (ASI), is a promising approach to treat or prevent autoimmune disorders. Different optimization protocols (immunization routes, delivery systems, and approaches) are being developed to implement ASI against self-proteins. Including appropriate adjuvants, altered peptide ligand, and using multipeptides are approaches that can be used to specifically target autoimmunity. This review explores various ASI application methods, including different routes of antigen specific sensitization, delivery systems, immunomodulators containing specific antigens, and other targeted approaches that have been successfully demonstrated to have therapeutic effects on autoimmune diseases. PMID- 29588070 TI - Parasite allergens. AB - Human IgE against helminths is a normal component of the whole protective response elicitesd during infection, when specific IgE to a great number of antigens is produced; however, few of those IgE binding components are actually allergens. In general, considering the strong Th2/IgE responses during helminth infections is intriguing that they are not usually associated with allergic symptoms, which probably (but not exclusively) depends on parasite-induced immunomodulation. However, allergic manifestations have been described during some helminth infections such as ascariasis, strongyloidiasis, anisakiasis and hydatidosis. In addition, there is evidence that helminthiases (e.g. ascariasis) can increase symptoms in allergic patients. Furthermore, allergic reactions during anti-helminth vaccination have been observed, a problem that also could be associated to the future use of parasite derived immunomodulators. Therefore, identification and characterization of helminth allergens is a matter of increasing research and a great number of IgE binding antigens have been found (www.allergen.org and www.allergome.org). Here we describe only a small group of them, for which allergenic activity (the ability to induce IgE mediated inflammation) have been clinical or experimentally demonstrated. Ascaris lumbricoides tropomyosin (Asc l 3) has strong allergenic activity; in the Tropics it has been associated with asthma and asthma severity, suggesting clinical relevance. In addition, due to its cross reactivity with mite tropomyosins this allergen could influence house dust mite (HDM) allergy diagnosis. Characterized Ascaris allergens also include the polyprotein As s 1 (ABA-1) and the Glutathione transferase As l 13. Other helminth allergens include Anisakis simplex Ani s 1, Ani s 4, Ani s 7 and Ani s 9; Necator americanus NaASP2q and Nacal1 and Schistosoma mansoni SmVAL4 and Sm22.6. Future work on helminth IgE binding antigens will help to understand several aspects of allergenicity and allergenic activity, among them the increasing finding of IgE binding molecules that not induce allergic symptoms.

PMID- 29588072 TI - Dose escalation for prostate stereotactic ablative radiotherapy (SABR): Late outcomes from two prospective clinical trials. AB - PURPOSE: Optimal prostate SABR dose-fractionation is unknown. This study compares long-term outcomes from two prospective trials. METHODS: Study1 patients had low risk PCa and received 35 Gy/5. Study2 patients had low/intermediate-risk PCa and received 40 Gy/5. Biochemical failure (BF) was defined as nadir + 2. RESULTS: 114 patients were included (study1, n = 84; study2, n = 30). Median follow-up was 9.6 years and 6.9 years. Median nPSA was 0.4 and 0.1 ng/ml. Nine patients had BF (8 in study1, 1 in study2); two were managed with ADT and four had local salvage. The BF rate was 2.5% and 12.8% at 5 and 10 years for study1 and 3.3% at 5 years for study 2. BF probability was 0% if PSA <0.4 at 4 years, and 20.5% at 10 years if PSA >=0.4 (p = 0.02). Nine patients died, none of PCa. No patient has metastases or castrate-resistance. At 10 years, OS and CSS were 90.4% (p = 0.25) and 100%. CONCLUSIONS: Dose-escalated prostate SABR was associated with lower nPSAs but no difference in BF, OS, CSS or MFS. PSA <0.4 at 4 years was a predictor of biochemical control. Half of patients with BF were successfully salvaged. Given that this is a favorable-risk cohort, longer follow-up will be needed to see if the lower nPSA translates into lower BF rates. PMID- 29588073 TI - miR-22 regulates C2C12 myoblast proliferation and differentiation by targeting TGFBR1. AB - Recently, miR-22 was found to be differentially expressed in different skeletal muscle growth period, indicated that it might have function in skeletal muscle myogenesis. In this study, we found that the expression of miR-22 was the most in skeletal muscle and was gradually up-regulated during mouse myoblast cell (C2C12 myoblast cell line) differentiation. Overexpression of miR-22 repressed C2C12 myoblast proliferation and promoted myoblast differentiation into myotubes, whereas inhibition of miR-22 showed the opposite results. During myogenesis, we predicted and verified transforming growth factor beta receptor 1 (TGFBR1), a key receptor of the TGF-beta/Smad signaling pathway, was a target gene of miR-22. Then, we found miR-22 could regulate the expression of TGFBR1 and down-regulate the Smad3 signaling pathway. Knockdown of TGFBR1 by siRNA suppressed the proliferation of C2C12 cells but induced its differentiation. Conversely, overexpression of TGFBR1 significantly promoted proliferation but inhibited differentiation of the myoblast. Additionally, when C2C12 cells were treated with different concentrations of transforming growth factor beta 1 (TGF-beta1), the level of miR-22 in C2C12 cells was reduced. The TGFBR1 protein level was significantly elevated in C2C12 cells treated with TGF-beta1. Moreover, miR-22 was able to inhibit TGF-beta1-induced TGFBR1 expression in C2C12 cells. Altogether, we demonstrated that TGF-beta1 inhibited miR-22 expression in C2C12 cells and miR-22 regulated C2C12 cell myogenesis by targeting TGFBR1.

AB - The French healthcare insurance databases have proven to be valuable tools for the conduct of pharmaco-epidemiological studies with regards to the size of the population covered and that of the available information. Their wider use in the field of pediatric pharmacoepidemiology is of paramount importance given the existing gap of knowledge in the use and effects of many drugs in children and adolescents as well as the difficulties to conduct clinical research studies in this age population. However, because of the architectural complexity of these databases and their specificities, specific expertise should be developed in order to ensure the reliability of studies based on these data. To this purpose, it is important to facilitate knowledge sharing through national collaborative projects. PMID- 29588075 TI - Surgical management of functional constipation: An intermediate report of a new approach using a laparoscopic sigmoid resection combined with malone appendicostomy. AB - INTRODUCTION: We previously reported our surgical technique for functional constipation for patients who have failed medical management using a novel collaborative approach with gastroenterology input, pre-operative contrast enema, colonic manometry, and laxative protocol combined with a laparoscopic colonic resection with Malone appendicostomy. Now we report our intermediate outcomes. METHODS: Patients who failed bowel management program for functional constipation were reviewed from 3/2014-2/2017. Patients with Hirschsprung disease, anorectal malformation, tethered cord, spina bifida, Trisomy 21, cerebral palsy, mitochondrial disease, or prior colon resection were excluded. RESULTS: Of 31 patients (14 females; median age 12years, follow-up 10.3months) with functional constipation and failed medical management, 26 (84%) had preoperative colonic manometry which, in addition to the contrast enema, guided laparoscopic colon resection. Ten patients (32.3%) are clean with no flushes (1 takes no laxatives, 8 are on low dose laxatives only, and 1 patient was clean on laxatives but chose to switch back to flushes). Of the 21 patients that remain on antegrade flushes, 20 (95.2%) are clean, and one patient (4.8%) continues to soil. We define clean as no soiling and no abnormal stool burden on x-ray. Laxative trials are planned for all patients on an antegrade flush regimen. CONCLUSION: Our intermediate results show that laparoscopic colon resection with Malone appendicostomy allows the majority of patients to be clean on antegrade flushes, and some to be on no or minimal laxatives. TYPE OF STUDY: Retrospective review. LEVEL OF EVIDENCE: 3. PMID- 29588076 TI - Intestinal resection-associated metabolic syndrome. AB - BACKGROUND: Short bowel syndrome occurs following massive small bowel resection (SBR) and is one of the most lethal diseases of childhood. We have previously demonstrated hepatic steatosis, altered gut microbiome, and increased fat deposition in our murine model of SBR. These novel findings prompted us to investigate potential alterations in glucose metabolism and systemic inflammation following intestinal resection. METHODS: Male C57BL6 mice underwent 50% proximal SBR or sham operation. Body weight and composition were measured. Fasting blood glucose (FBG), glucose, and insulin tolerance testing were performed. Small bowel, pancreas, and serum were collected at sacrifice and analyzed. RESULTS: SBR mice gained less weight than shams after 10weeks. Despite this, FBG in resected mice was significantly higher than sham animals. After SBR, mice demonstrated perturbed body composition, higher blood glucose, increased pancreatic islet area, and increased systemic inflammation compared with sham mice. Despite these changes, we found no alteration in insulin tolerance after resection. CONCLUSIONS: After massive SBR, we present evidence for abnormal body composition, glucose metabolism, and systemic inflammation. These findings, coupled with resection-associated hepatic steatosis, suggest that massive SBR (independent of parenteral nutrition) results in metabolic consequences not previously described and provides further evidence to support the presence of a novel resection-associated metabolic syndrome. PMID- 29588077 TI - Fatigue failure load of two resin-bonded zirconia-reinforced lithium silicate glass-ceramics: Effect of ceramic thickness. AB - OBJECTIVES: To evaluate the effect of ceramic thickness on the fatigue failure load of two zirconia-reinforced lithium silicate (ZLS) glass-ceramics, adhesively cemented to a dentin analogue material. METHODS: Disc-shaped specimens were allocated into 8 groups (n=25) considering two study factors: ZLS ceramic type (Vita Suprinity - VS; and Celtra Duo - CD), and ceramic thickness (1.0; 1.5; 2.0; and 2.5mm). A trilayer assembly (phi=10mm; thickness=3.5mm) was designed to mimic a bonded monolithic restoration. The ceramic discs were etched, silanized and luted (Variolink N) into a dentin analogue material. Fatigue failure load was determined using the Staircase method (100,000 cycles at 20Hz; initial fatigue load ~60% of the mean monotonic load-to-failure; step size ~5% of the initial fatigue load). A stainless-steel piston (phi=40mm) applied the load into the center of the specimens submerged in water. Fractographic analysis and Finite Element Analysis (FEA) were also performed. RESULTS: The ceramic thickness influenced the fatigue failure load for both ZLS materials: Suprinity (716N up to 1119N); Celtra (404N up to 1126N). FEA showed that decreasing ceramic thickness led to higher stress concentration on the cementing interface. SIGNIFICANCE: Different ZLS glass-ceramic thicknesses influenced the fatigue failure load of the bonded system (i.e. the thicker the glass ceramic is, the higher the fatigue failure load will be). Different microstructures of the ZLS glass-ceramics might affect the fatigue behavior. FEA showed that the thicker the glass ceramic is, the lower the stress concentration at the tensile surface will be. PMID- 29588078 TI - Pulsed-Doppler evaluation of renal perfusion during pulsatile extracorporeal circulation. A pilot study. AB - INTRODUCTION: Acute renal failure (ARF) after cardiac surgery is a risk factor associated with mortality and use of resources. Some studies have reported beneficial effects of pulsatile flow on cardiopulmonary bypass (CPB) on renal function. The aim of this study is to describe the echographic morphology of the renal arterial wave modifying the parameters of pulsatile CPB. MATERIAL AND METHOD: Descriptive study was performed on 10 patients without previous AFR and undergoing cardiac surgery with CPB. Pre-, intra- and post-surgery renal ultrasound was performed. During pulsatile CPB, the amplitude and the baseline flow were modified. Recordings of pulsed Doppler in intrarenal arteries were obtained by measuring maximum systolic velocity, minimum diastolic velocity, resistance index (RI) and acceleration time (AT). RESULTS: Statistical differences were found in ultrasounds pre-CPB between A50F50 modality (P=.013), A50F30 (P=.013) and A60F50 (P=.003). No statistically significance was found with A30F30 modality (P=.125). CONCLUSIONS: The decrease in the amplitude and the baseline flow of pulsatility during CPB shows a renal ultrasound morphology that is more similar to the physiological one. Subsequent studies using these characteristics during pulsatile CPB could thus show perfusion over the ARF that occurs after cardiac surgery. PMID- 29588080 TI - Getting to the root of the problem. PMID- 29588079 TI - Risk of Cardiovascular Disease and Venous Thromboembolism Among Patients With Incident ANCA-Associated Vasculitis: A 20-Year Population-Based Cohort Study. AB - OBJECTIVE: To assess the cardiovascular disease (CVD) and venous thromboembolism (VTE) risks among patients with newly diagnosed antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV). PATIENTS AND METHODS: A population based incident AAV cohort of 58 patients diagnosed between 1996 and 2015 in Olmsted County, MN, was identified by medical record review. For each patient, 3 age- and sex-matched non-AAV comparators were randomly selected from the same population and assigned an index date corresponding to the AAV incidence date. Medical records of cases and comparators were reviewed for CVD events, which included cardiac events (coronary artery disease, heart failure, and atrial fibrillation), cerebrovascular accidents (CVA), peripheral vascular disease (PVD), and VTE, which included deep vein thrombosis (DVT) and pulmonary embolism (PE). RESULTS: Baseline total cholesterol, high-density lipoprotein, and current smoking rate were lower in AAV than in comparators (P=.03, P=.01, and P=.04, respectively), whereas other CVD risk factors and Framingham risk score were not significantly different between the 2 groups. The CVD events developed in 13 patients and 17 comparators, corresponding to a more than 3-fold increased risk (hazard ratio [HR], 3.15; 95% CI, 1.51-6.57). By subtypes, risks were increased for cardiac events (HR, 2.96; 95% CI, 1.42-6.15) and CVA (HR, 8.16; 95% CI, 2.45 27.15), but not for PVD. The HR for VTE was 3.26 (95% CI, 0.84-12.60), significantly increased for DVT (HR, 6.25; 95% CI, 1.16-33.60), but not for PE (HR, 1.33; 95% CI, 0.23-7.54). CONCLUSION: Despite a similar prevalence of CVD risk factors at baseline, the risk of CVD is more than 3-fold higher and for CVA 8-fold higher in patients with incident AAV than in matched comparator subjects.

AB - A dragonfly larva migrates from the water to the shore, perches on a plant stem and grasps it with strongly flexed legs. Adult legs inside the larval exoskeleton fit to the larval legs joint-to-joint. The adult emerges with stretched legs. During the molt, an imaginal leg must follow all the angles in exuvial joints. In turn, larval apodemes are withdrawn from imaginal legs. We visualized transient shapes of the imaginal legs by the instant fixation of insects at different moments of the molt, photographed isolated exuvial legs with the imaginal legs inside and then removed the exuvial sheath. Instant shapes of the imaginal tibia show sharp intrapodomere bends copying the angle in the larval femoro-tibial joint. The site of bending shifts distad during the molt. This is possible if the imaginal leg is pliable. The same problem of leg squeezing is also common in hemimetabolous insects as well as in other arthropods, whereas holometabolous insects overcome problems of a tight confinement either by using leg pliability in other ways but not squeezing (cyclorrhaphan flies, mosquitoes) or by pulling hardened legs out without change of their pupal zigzag configuration (moths, ants, honey bees). The pupal legs are not intended to grasp any external substrate. PMID- 29588084 TI - Hepatopulmonary Syndrome and Diffuse Interstitial Lung Disease: An Unusual Combination.

Although progress in cancer therapy and the advent of new anticancer agents such as molecular targeted drugs have improved the outcomes of patients with cancer, the incidence of cancer-therapy-related thromboembolism is increasing, and the management of this adverse reaction has become a major problem. Cancer is intimately related to thrombosis. Thrombus formation results from the complex interaction of various factors, such as tissue factors, coagulation abnormalities, activated platelet activation, activated adhesion activation, and endothelial cell dysfunction. Thrombosis has an impact on cancer proliferation and extension. The condition known as "cancer-related thrombosis" must therefore be managed differently from thrombosis in patients without cancer. PMID- 29588088 TI - The etiologic relation between disequilibrium and orthostatic intolerance in patients with myalgic encephalomyelitis (chronic fatigue syndrome). AB - BACKGROUND: Orthostatic intolerance (OI) causes a marked reduction in the activities of daily living in patients with myalgic encephalomyelitis (ME) or chronic fatigue syndrome. Most symptoms of OI are thought to be related to cerebral hypo-perfusion and sympathetic activation. Because postural stability is an essential element of orthostatic tolerance, disequilibrium may be involved in the etiology of OI. METHODS AND RESULTS: The study comprised 44 patients with ME (men, 11 and women, 33; mean age, 37+/-9 years), who underwent neurological examinations and 10-min standing and sitting tests. Symptoms of OI were detected in 40 (91%) patients and those of sitting intolerance were detected in 30 (68%). Among the 40 patients with OI, disequilibrium with instability on standing with their feet together and eyes shut, was detected in 13 (32.5%) patients and hemodynamic dysfunction during the standing test was detected in 19 (47.5%); both of these were detected in 7 (17.5%) patients. Compared with 31 patients without disequilibrium, 13 (30%) patients with disequilibrium more prevalently reported symptoms during both standing (100% vs. 87%, p=0.43) and sitting (92% vs. 58%, p=0.06) tests. Several (46% vs. 3%, p<0.01) patients failed to complete the 10 min standing test, and some (15% vs. 0%, p=0.15) failed to complete the 10-min sitting test. Among the seven patients with both hemodynamic dysfunction during the standing test and disequilibrium, three (43%) failed to complete the standing test. Among the 6 patients with disequilibrium only, 3 (50%) failed while among the 12 patients with hemodynamic dysfunction only, including 8 patients with postural orthostatic tachycardia, none (0%, p=0.02) failed. CONCLUSIONS: Patients with ME and disequilibrium reported not only OI but also sitting intolerance. Disequilibrium should be recognized as an important cause of OI and appears to be a more influential cause for OI than postural orthostatic tachycardia in patients with ME. PMID- 29588089 TI - An international comparison of risk factors between two regions with distinct differences in asthma prevalence. AB - BACKGROUND AND PURPOSE: Investigation of the geographic variation in asthma prevalence can improve our understanding of asthma etiology and management. The purpose of our investigation was to compare the prevalence of asthma and wheeze among adolescents living in two distinct international regions and to investigate reasons for observed differences. METHODS: A cross-sectional survey of 13-14 year olds was completed in Saskatoon, Canada (n=1200) and Skopje, Republic of Macedonia (n=3026), as part of the International Study of Asthma and Allergies in Childhood (ISAAC) Phase 3 study. Surveys were self-completed by students following the ISAAC protocol. Multiple logistic regression models were used to investigate associations with reports of asthma and current wheeze. A mediation analysis was then completed. RESULTS: Asthma prevalence was much higher in Saskatoon than Skopje (21.3% vs. 1.7%) as was the prevalence of current wheeze (28.2% vs. 8.8%). Higher paracetamol (acetaminophen) use was a consistent risk factor for asthma and wheeze in both locations and showed dose-response relationships. In both countries, paracetamol use and physical activity mediated some of the association for both asthma and wheeze. In Saskatoon, among those with current wheeze, 42.6% reported ever having a diagnosis of asthma compared to 10.2% among Skopje adolescents. CONCLUSIONS: The results suggest that the variation in risk factors between the two locations may explain some of the differences in the prevalence of asthma and wheeze between these two study sites. However, diagnostic labeling patterns should not be ruled out as another potential explanatory factor.

Impact of an incentivisation campaign about influenza vaccination for patients attending the Dunkerque cystic fibrosis treatment centre and their health care workers]. AB - INTRODUCTION: The main aim of this study is to evaluate the effectiveness of preventive actions regarding influenza in the studied populations. The secondary objective is to analyze and understand the mechanisms which bring about a behavioural change regarding influenza vaccination. METHODS: The interventional and prospective study was undertaken in the form of an anonymous questionnaire about influenza vaccination coverage and about the reasons for vaccinating or not vaccinating. The studied populations were patients followed for cystic fibrosis (n=67) in the Dunkerque cystic fibrosis treatment centre and their health care workers (n=117), before (April 2014) and after (April 2015) an information campaign and primary prevention actions (vaccination in the workplace with expanded time slots) in collaboration with the department of occupational medicine. RESULTS: In 2015, the vaccination coverage rate of health care workers rose to 65.63%, that is to say 2.38 times more than in 2014 (27.55%). This difference is significant (chi2[1]=29.17, P<0.0001). However, no significant difference between 2014 and 2015 was observed among patients (children and adults) (chi2[1]=0.24, NS) whose vaccination coverage was already optimal before the study. CONCLUSIONS: Raising awareness among health care workers about vaccination against influenza increases the coverage rate and decreases outbreaks of virus infection in the care services and among patients at risk. Three main levers were identified: the necessity of providing information on influenza vaccination to health care workers, the ease of vaccination access and the attitude towards vaccination of supervisory staff (health executives/doctors).

PMID- 29588095 TI - The utilization of automated external defibrillators in Taiwan. AB - BACKGROUND: Increasing attention to care of patient succumbed to out-of-hospital cardiac arrest (OHCA) and evidence for improved survival have resulted in many countries to encourage the use automated external defibrillators (AEDs) by legislation. In Taiwan, the amendment of the Emergency Medical Services Act mandated the installation of AEDs in designated areas in 2013. Since then, 6151 AEDs have been installed and registered in mandated and non-mandated locations. The purpose of this study was to investigate the utilization of AEDs at mandated and non-mandated locations. METHODS: This paper analyzed 217 cases in whom AEDs was used between July 11, 2013 and July 31, 2015. Descriptive statistics were used to analyze the data. RESULTS: The highest frequency of AEDs used was in long term care facilities, accounting for 34 (15.7%) cases. The second and third highest was in schools and commuting stations. The highest utilization rate of registered AED was in long-term care facilities (73.9%), the second was in residential areas, and the third was in hot spring areas. Employees at the designated locations or medical personnel operated the AED in 143 cases (84.6%), and bystanders, relatives, friends or others operated the AEDs in 26 cases (15.4%). On-site Return of Spontaneous Circulation (ROSC) after applying AEDs occurred in 76 cases (45.8%). CONCLUSIONS: Long-term care facilities had the highest utilization of AEDs and government should pay more attention to enforce the installing of AEDs in these places. The government also needs to promote the education public on how to search the AEDs locations. PMID- 29588096 TI - No association of CYP2E1 genetic polymorphisms with alcohol dependence in Han Taiwanese population. AB - Cytochrome P450 2E1 (CYP2E1) gene is one of the candidate genes for alcohol dependence (AD). Four single nucleotide polymorphisms (SNPs) of CYP2E1 gene (CYP2E1*1D, *5B, *6 and *1B) have been associated with AD previously in other ethnic populations. To date, only CYP2E1*5B and *6 SNPs have been investigated in relation to AD in our population. The objective of the study was to examine the genetic associations of CYP2E1 covering the four above-noted SNPs conjointly with AD in Han Taiwanese population based on single SNP analysis and haplotype-based approach. We enrolled a total of 340 patients fulfilling DSM-IV-TR diagnostic criteria of AD and 319 healthy controls and genotyped them for the above four SNPs of CYP2E1 gene. By comparing the differences of genotype, allele, and pertinent haplotype frequencies, we did not support a genetic association between CYP2E1 and AD in Han Taiwanese either by single allele tests or haplotype-based analyses. PMID- 29588097 TI - Multi-class multi-residue analysis of veterinary drugs in meat using enhanced matrix removal lipid cleanup and liquid chromatography-tandem mass spectrometry. AB - This study presents the development and validation of a quantitation method for the analysis of multi-class, multi-residue veterinary drugs using lipid removal cleanup cartridges, enhanced matrix removal lipid (EMR-Lipid), for different meat matrices by liquid chromatography tandem mass spectrometry detection. Meat samples were extracted using a two-step solid-liquid extraction followed by pass through sample cleanup. The method was optimized based on the buffer and solvent composition, solvent additive additions, and EMR-Lipid cartridge cleanup. The developed method was then validated in five meat matrices, porcine muscle, bovine muscle, bovine liver, bovine kidney and chicken liver to evaluate the method performance characteristics, such as absolute recoveries and precision at three spiking levels, calibration curve linearity, limit of quantitation (LOQ) and matrix effect. The results showed that >90% of veterinary drug analytes achieved satisfactory recovery results of 60-120%. Over 97% analytes achieved excellent reproducibility results (relative standard deviation (RSD) < 20%), and the LOQs were 1-5 MUg/kg in the evaluated meat matrices. The matrix co-extractive removal efficiency by weight provided by EMR-lipid cartridge cleanup was 42-58% in samples. The post column infusion study showed that the matrix ion suppression was reduced for samples with the EMR-Lipid cartridge cleanup. The reduced matrix ion suppression effect was also confirmed with <15% frequency of compounds with significant quantitative ion suppression (>30%) for all tested veterinary drugs in all of meat matrices. The results showed that the two-step solid-liquid extraction provides efficient extraction for the entire spectrum of veterinary drugs, including the difficult classes such as tetracyclines, beta-lactams etc. EMR-Lipid cartridges after extraction provided efficient sample cleanup with easy streamlined protocol and minimal impacts on analytes recovery, improving method reliability and consistency. PMID- 29588098 TI - Validation and application of analytical method for glyphosate and glufosinate in foods by liquid chromatography-tandem mass spectrometry. AB - A reliable and sensitive method was developed for simultaneous determination of glyphosate and glufosinate in various food products by liquid chromatography tandem mass spectrometry. Based on extraction, derivatization with 9 fluorenylmethylchloroformate and purification on solid phase extraction column, quantification was done by using isotopic-labeled analytes as internal standard and calibration in matrix. Good selectivity and sensitivity were achieved with a limit of quantification of 5 MUg/kg. The recoveries of these two pesticides ranged from 91% to 114% with inter-day and relative standard deviation of 3.8 6.1% in five matrices of cereal group spiked at 5, 10, and 20 MUg/kg. An accuracy profile was performed for method validation, demonstrating the accuracy and precision of the method for the studied food groups. The verification results in expanded food groups indicated extensive applicability for the analysis of glyphosate and glufosinate. Finally, the developed method was applied to analyze 136 food samples including milk-based baby foods from the French Agency for Food, Environmental and Occupational Health & Safety. Glyphosate residues were detected in two breakfast cereal samples (6.0 and 34 MUg/kg). Glufosinate residues were found in a sample of boiled potatoes (9.8 MUg/kg). No residues were detected in the other samples, including milk-based baby foods with limits of detection ranging from 1 to 2 MUg/kg. The method has been applied for routine national monitoring of glyphosate and glufosinate in various foods. PMID- 29588099 TI - High temperature multidimensional gas chromatographic approach for improved separation of triacylglycerols in olive oil. AB - Heart-cut multidimensional gas chromatographic (H/C MDGC) methods under suitable flow and high temperature (T) program conditions were developed to separate olive oil triacylglycerols (TAGs). Different column sets were selected for further evaluation, each with relatively short non-polar first dimension (1D) and mid polar second dimension (2D) columns of high T limits (350 degrees C). The 1D separation displayed three major groups of peaks in an area ratio of approximately 5:33:62 (of increasing retention), using flame ionisation detection (FID). Four groups of minor peaks, with 2 of them located between the major peaks, were also detected. The H/C fractions of the minor peaks, and sub-sampled regions across the major peaks eluting from the 1D outlet, were cryotrapped at the 2D inlet. The trapped TAGs then underwent temperature programmed 2D separation. Each of the 'H/C' zones generally gave 2-5 - and in some cases more - separated peaks of TAGs on the 2D column, under suitable flow condition and phase polarity that resulted in improved separation. Six sub-sampled H/Cs from various regions of the individual peaks from the 1D column were simultaneously trapped and released to 2D, resulting in apparently more than 22 individual TAG peaks. According to their different retention times, different TAGs were revealed within each of the 3 major groups, using H/C sub-sampling. A comprehensive sampling strategy that covers most of the 1D peaks further revealed the presence of more TAGs in the olive oil sample. This tandem column strategy was able to resolve more components than that usually observed on a single column. PMID- 29588100 TI - Systematic profiling and comparison of the lipidomes from Panax ginseng, P. quinquefolius, and P. notoginseng by ultrahigh performance supercritical fluid chromatography/high-resolution mass spectrometry and ion mobility-derived collision cross section measurement. AB - Lipidomics currently is still confronted with challenges from chromatographic separation and lipids identification. Here we report a lipidomics platform by integrating ultrahigh performance supercritical fluid chromatography/quadrupole time-of-flight mass spectrometry (UHPSFC/QTOF-MS) and collision cross section (CCS) measurement using ion mobility spectroscopy/time-of-flight mass spectrometry (IMS/QTOF-MS), aiming to enhance the profiling performance and identification reliability of lipids. The lipidomes extracted from three congeneric Panax species (P. ginseng, P. quinquefolius, and P. notoginseng) by methyl tert-butyl ether are comprehensively profiled and compared by use of this platform. A potent UHPSFC/QTOF-MS approach was developed on a 1.7-MUm particles packed Torus 2-PIC column using CH3OH (in CO2) as a modifier and CH3OH/0.2 mM ammonium acetate as the makeup liquid, enabling well resolution of six lipid subclasses by both positive and negative MSE modes. In contrast to the reversed phase chromatography, "normal-phase" like elution order and better resolution of polar lipids and some lipid isomers were achieved by UHPSFC separation. Pattern recognition chemometric analysis of 60 batches of Ginseng samples ultimately unveiled 24 lipid markers, of which triacylglycerols were the most important. Aside from the automated MS database searching against HMDB and LIPID MAPS, the application of CCS retrieval or CCS prediction improved lipid identification by reducing the possible hits. In conclusion, this integral platform can significantly improve the chromatographic separation and the reliability of lipids identification in lipidomics studies. It is the first report that systematically compares the lipidomic difference of three reputable Panax species, providing useful information for their quality control in addition to ginsenoside analysis. PMID- 29588101 TI - Front- and rear-facing horizontal sound localization results in adults with unilateral hearing loss and normal hearing. AB - Binaural hearing allows listeners to take advantage of auditory cues that are necessary for sound localization. Patients with asymmetric or unilateral hearing loss receive degraded or absent binaural cues and often demonstrate decreased sound localization in the horizontal plane. Given the importance of sound localization for everyday function, there is a need for clinically feasible methods to evaluate localization, particularly as validation of intervention for patients with unilateral hearing loss. The present study compared sound localization results obtained for front-facing and rear-facing soundfield systems and for a rear-facing head related transfer function (HRTF) system in two hearing groups, listeners with normal hearing and those with unilateral hearing loss. Results between the three systems were highly correlated and repeatable. Neither age nor a pure-tone average of 0.5, 1, 2 and 4 kHz correlated with localization performance among normal hearing participants. Among the UHL group, age and onset of severe to profound hearing loss were positively correlated with localization results; length of deafness was negatively correlated. Behavioral chance performance was established for localization with rear-facing HRTF and rear facing soundfield test systems; group mean results for unilateral hearing loss participants were significantly better than chance. Continued work is needed in developing clinically feasible evaluation methods for patients with asymmetric or unilateral hearing loss, particularly as the effects of treatment options are assessed. PMID- 29588102 TI - Women treated for gynaecological cancer during young adulthood - A mixed-methods study of perceived psychological distress and experiences of support from health care following end-of-treatment. AB - OBJECTIVE: To investigate the prevalence and predictors of cancer-related distress in younger women treated for gynaecological cancer, and to explore women's needs and experiences of psychosocial support following end-of-treatment. METHODS: Data were collected from 337 gynaecological cancer survivors, 19-39years at diagnosis, using a study-specific questionnaire and the Swedish Quality Register of Gynaecologic Cancer. Predictors of distress were investigated with multivariable logistic regression analysis. Open-ended questions were analysed with content analysis. RESULTS: The prevalence of cancer-related distress was 85% (n=286) including fear of cancer-recurrence (n=175, 61%), anxiety (n=152, 53%), depression (n=145, 51%), fear of death (n=91, 32%), concerns regarding sexuality (n=87, 34%) and fertility (n=78, 27%), and changed body image (n=78, 27%). Multi modal treatment (OR 2.25, 95% CI 1.13-4.49) and a history of psychological distress (OR 3.44, 95% CI 1.41-8.39) predicted cancer-related distress. The majority of women experiencing distress also reported a need for support after end-of-treatment (n=205, 71%). One-third of those receiving support reported the received support as inadequate (n=55, 34%). Eight categories described reasons for not seeking support, e.g., lacked strength to seek professional support and too busy managing every-day life and, wanted help but did not know who to turn to. Four categories described reasons for not receiving sought support e.g., found it difficult to openly express feelings, psychosocial care was under dimensioned, insufficient and unprofessional. CONCLUSION: Results identify the importance of support and longer-term follow-up for young survivors of gynaecological cancer. The support needs to be organised to meet this group's specific needs. PMID- 29588103 TI - Black mother's intention to vaccinate daughters against HPV: A mixed methods approach to identify opportunities for targeted communication. AB - OBJECTIVE: The cervical cancer disparity continues to exist and has widened between Black and non-Hispanic White women. Human Papillomavirus (HPV) vaccines could potentially reduce this disparity, yet remain underused among Black female adolescents. We investigated psychosocial and cultural factors associated with Black mothers' intentions to vaccinate their daughters against HPV, and explored views toward a HPV vaccine mandate. METHODS: In this quantitative dominant, mixed methods study, cross sectional surveys (n=237) and follow-up semi-structured interviews (n=9) were conducted with Black mothers of daughters. A 2-step logistic regression determined factors associated with Black mothers' intention. Thematic content analysis determined emerging themes. RESULTS: Perceived susceptibility (p=.044), perceived barriers (p<.001), and subjective norms (p=.001) were significant predictors of maternal HPV vaccination intentions. Follow-up interviews provided insight into factors influencing mothers' intentions. Mothers with low intentions did not perceive their daughter to be currently sexually active or in near future, thus, not at HPV risk. Pediatricians were identified as the most influential person on maternal decision-making if there was a pre-existing relationship. However, many mothers had not received a pediatricians' recommendation for their daughters. Barriers influencing mother's decision-making include knowledge, daughters' age, and mistrust in pharmaceutical companies and physicians. Mothers were not in favor of the HPV vaccine mandate. CONCLUSIONS: Findings demonstrate the need to develop and evaluate physician-led interventions on HPV and vaccine importance, and engage these mothers in intervention development to build trust between physicians, researchers, and Black mothers to improve HPV vaccine uptake in Black female adolescents.

AB - The main purpose of this pilot plant study was to compare degradation of five microcontaminants (MCs) (antipyrine, carbamazepine, caffeine, ciprofloxacin and sulfamethoxazole at 100 MUg/L) by solar photo-Fenton mediated by EDDS and solar/Fe:EDDS/S2O82-. The effects of the Fe:EDDS ratio (1:1 and 1:2), initial iron species (Fe(II) or Fe(III) at 0.1 mM) and oxidizing agent (S2O82- or H2O2 at 0.25-1.5 mM) were evaluated. The higher the S2O82- concentration, the faster MC degradation was, with S2O82- consumption always below 0.6 mM and similar degradation rates with Fe(II) and Fe(III). Under the best conditions (Fe 0.1 mM, Fe:EDDS 1:1, S2O82- 1 mM) antipyrine, carbamazepine, caffeine, ciprofloxacin and sulfamethoxazole at 100 MUg/L where 90% eliminated applying a solar energy of 2 kJ/L (13 min at 30 W/m2 solar radiation <400 nm). Therefore, S2O82- promotes lower consumption of EDDS as Fe:EDDS 1:1 was better than Fe:EDDS 1:2. In photo Fenton-like processes at circumneutral pH, EDDS with S2O82- is an alternative to H2O2 as an oxidizing agent.

AB - PURPOSE: In this proof-of-concept study, we proposed 3-D-printed mold-guided breast-conserving surgery (BCS) in breast cancer patients. PATIENTS AND METHODS: Pathologically confirmed and eligible breast cancer patients received magnetic resonance imaging examinations before BCS. The information on the shape, size, and location of the tumor relative to the nipple was extracted and analyzed. We used a 3-D printing technique to produce a mold to guide BCS for breast cancer patients. RESULTS: We performed 3-D-printed mold-guided BCS in 8 breast cancer patients. All of the patients had negative surgical margins, confirmed by intraoperative and postoperative pathologic examinations. CONCLUSION: The 3-D printed mold-guided BCS approach is a feasible way to achieve negative surgical margins. A prospective designed cohort study, with more patients included and a longer follow-up, is needed to further confirm its long-term oncologic safety.

AB - BACKGROUND: Although flexible-ring annuloplasty is more inclined to increase the transmitral gradient over time, its effect on the tricuspid annulus is unknown. This study was conducted to evaluate serial changes in mean pressure gradient (mPG) across tricuspid and mitral valves after simultaneous dual implantation of flexible bands. METHODS: Seventy-one patients (median age, 61.6 years; IQR: 50.8 69.0 years) underwent simultaneous mitral/tricuspid annuloplasties using St. Jude Tailor rings. Serial mPGs across mitral and tricuspid valves were evaluated at three postoperative time points: predischarge, 3 years, and 5 years. To gauge the effects and clinical outcomes of prophylactic intervention, patients were categorised as tricuspid regurgitation (TR)>=moderate or TR=moderate, p=0.542; TR=moderate degree displayed TR>=moderate at baseline, and overall mortality was higher in the TR>=moderate group (p=0.01). CONCLUSIONS: Flexible-band annuloplasty did not promote stenosis of tricuspid valves at mid-term follow-up. These findings confirm the safety of prophylactic tricuspid annuloplasty (via flexible band) as an adjunct to mitral annuloplasty. PMID- 29588108 TI - How to avoid the inappropriate use of antibiotics in upper respiratory tract infections? A position statement from an expert panel. AB - INTRODUCTION: Bacterial resistance burden has increased in the past years, mainly due to inappropriate antibiotic use. Recently it has become an urgent public health concern due to its impact on the prolongation of hospitalization, an increase of total cost of treatment and mortality associated with infectious disease. Almost half of the antimicrobial prescriptions in outpatient care visits are prescribed for acute upper respiratory infections, especially rhinosinusitis, otitis media, and pharyngotonsillitis. In this context, otorhinolaryngologists play an important role in orienting patients and non-specialists in the utilization of antibiotics rationally and properly in these infections. OBJECTIVES: To review the most recent recommendations and guidelines for the use of antibiotics in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, adapted to our national reality. METHODS: A literature review on PubMed database including the medical management in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, followed by a discussion with a panel of specialists. RESULTS: Antibiotics must be judiciously prescribed in uncomplicated acute upper respiratory tract infections. The severity of clinical presentation and the potential risks for evolution to suppurative and non suppurative complications must be taken into 'consideration'. CONCLUSIONS: Periodic revisions on guidelines and recommendations for treatment of the main acute infections are necessary to orient rationale and appropriate use of antibiotics. Continuous medical education and changes in physicians' and patients' behavior are required to modify the paradigm that all upper respiratory infection needs antibiotic therapy, minimizing the consequences of its inadequate and inappropriate use. PMID- 29588111 TI - Number of advanced adenomas on index colonoscopy: Important risk factor for metachronous advanced colorectal neoplasia. AB - BACKGROUND/AIMS: Although the patients with multiple advanced adenomas (AA) in index colonoscopy may have an increased risk for subsequent advanced colorectal neoplasia (CRN), the current guidelines do not consider this factor. We aimed to compare the risk of metachronous advanced CRN according to the number of AAs. METHODS: A total of 2250 patients with >=1 adenoma at index colonoscopy were included. The patients were divided according to the number of AAs (1, 2 and >=3 AAs). The relative and 3-year absolute risk of metachronous advanced CRN was compared between the AA groups. RESULTS: The relative risk of metachronous advanced CRN was higher in the patients with >=3 AAs than in the patients with one AA (16.7% vs. 6.8%, p = 0.004). The 3-year absolute risk of metachronous advanced CRN was higher in the patients with >=3 AAs than in the patients with 1 2 AA (19.4% vs. 6.9%, p = 0.04). Having >=3 AAs (odds ratio, 5.42; 95% confidence interval 1.75-16.83) was a significant risk factor for developing advanced CRN. CONCLUSIONS: The risk of metachronous advanced CRN in the patients with >=3 AAs was higher than that in the patients with one or two AAs. More intensive surveillances might be needed for these patient groups. PMID- 29588112 TI - Regulation of Adipose Tissue Metabolism by the Endocannabinoid System. AB - White adipose tissue (WAT) stores excess energy as triglycerides, and brown adipose tissue (BAT) is specialized in dissipating energy as heat. The endocannabinoid system (ECS) is involved in a broad range of physiological processes and is increasingly recognized as a key player in adipose tissue metabolism. High ECS tonus in the fed state is associated with a disadvantageous metabolic phenotype, and this has led to a search for pharmacological strategies to inhibit the ECS. In this review we present recent developments that cast light on the regulation of adipose tissue metabolism by the ECS, and we discuss novel treatment options including the modulation of endocannabinoid synthesis and breakdown enzymes. PMID- 29588113 TI - Simulated learning environment experience in nursing students for paediatric practice. AB - The training of health professionals requires the acquisition of clinical skills in a safe and efficient manner, which is facilitated by a simulated learning environment (SLE). It is also an efficient alternative when there are limitations for clinical practice in certain areas. This paper shows the work undertaken in a Chilean university in implementing paediatric practice using SLE. Over eight days, the care experience of a hospitalized infant was studied applying the nursing process. The participation of a paediatrician, resident physician, nursing technician, and simulated user was included in addition to the use of a simulation mannequin and equipment. Simulation of care was integral and covered interaction with the child and family and was developed in groups of six students by a teacher. The different phases of the simulation methodology were developed from a pedagogical point of view. The possibility of implementing paediatric clinical practice in an efficient and safe way was confirmed. The experience in SLE was highly valued by the students, allowing them to develop different skills and abilities required for paediatric nursing through simulation. PMID- 29588114 TI - Post marathon cardiac troponin T is associated with relative exercise intensity. AB - OBJECTIVES: This study aimed to investigate whether measures of cardiopulmonary fitness and relative exercise intensity were associated with high sensitivity cardiac troponin T (cTnT) rise after a road marathon. METHODS: Fifty-two marathon runners (age 39+/-11 years, body mass 76.2+/-12.9kg, height 1.74+/-0.09m) attended the laboratory between 2 and 3 weeks prior to attempting the Brighton Marathon, UK. Running economy at 10kmh-1 (RE10) and race pace (RERP), ventilatory threshold (VT) and VO2max tests were completed. CTnT was measured within 48h prior to the marathon and within 10min of completing the marathon, using a high sensitivity assay. Heart rates (HR) were recorded throughout the marathon. RESULTS: Runners demonstrated a significant increase in cTnT over the marathon (pre-race 5.60+/-3.27ngL-1, post-race 74.52+/-30.39ngL-1, p<0.001). Markers of endurance performance such as running economy (10kmh-1 223+/-18mlkg-1km-1; race pace 225+/-22mlkg-1km-1), VT (38.5+/-6.4mlkg-1min-1) and VO2max (50.9+/-7.7mlkg 1min-1) were not associated with post-race cTnT. Runners exercise intensity correlated with post-race cTnT (mean HR %VT 104+/-5%, r=0.50; peak HR %VT 118+/ 8%, r=0.68; peak HR %VO2max 96+/-6, r=0.60, p<0.05) and was different between the low, medium and high cTnT groups (p<0.05). CONCLUSIONS: CTnT increases above reference limits during a marathon. Magnitude of cTnT rise is related to exercise intensity relative to ventilatory threshold and VO2max, but not individuals' absolute cardiopulmonary fitness, training state or running history. PMID- 29588115 TI - Dual energy X-ray absorptiometry positioning protocols in assessing body composition: A systematic review of the literature. AB - OBJECTIVES: To systematically identify and assess methods and protocols used to reduce technical and biological errors in published studies that have investigated reliability of dual energy X-ray absorptiometry (DXA) for assessing body composition. DESIGN: Systematic review. METHODS: Systematic searches of five databases were used to identify studies of DXA reliability. Two independent reviewers used a modified critical appraisal tool to assess their methodological quality. Data was extracted and synthesised using a level of evidence approach. Further analysis was then undertaken of methods used to decrease DXA errors (technical and biological) and so enhance DXA reliability. RESULTS: Twelve studies met eligibility criteria. Four of the articles were deemed high quality. Quality articles considered biological and technical errors when preparing participants for DXA scanning. The Nana positioning protocol was assessed to have a strong level of evidence. The studies providing this evidence indicated very high test-retest reliability (ICC 0.90-1.00 or less than 1% change in mean) of the Nana positioning protocol. The National Health and Nutrition Examination Survey (NHANES) positioning protocol was deemed to have a moderate level of evidence due to lack of high quality studies. However, the available studies found the NHANES positioning protocol had very high test-retest reliability. Evidence is limited and reported reliability has varied in papers where no specific positioning protocol was used or reported. CONCLUSIONS: Due to the strong level of evidence of excellent test-retest reliability that supports use of the Nana positioning protocol, it is recommended as the first choice for clinicians when using DXA to assess body composition. PMID- 29588116 TI - Use and Risk Perception of Electronic Nicotine Delivery Systems and Tobacco in Pregnancy. AB - INTRODUCTION: Given the rapid rise in availability and use, understanding the perception of electronic nicotine delivery systems (ENDS) products in pregnant women is vital. As more women of reproductive age use these products, it is likely that their use during pregnancy is also increasing. This study investigated the use of ENDS and tobacco cigarettes, along with knowledge and perceptions of associated health risks in pregnant women. METHODS: A cross sectional survey was conducted at a university-based obstetrical clinic. A 32 item self-administered survey was used to collect participants' knowledge, use, and risk perceptions of ENDS and tobacco smoking. Bivariate associations of demographics and ENDS user status were explored using Chi-square or Fisher's exact tests. Average differences in agreement with perception statements across ENDS user status were tested using ANOVA with Tukey's tests for multiple comparisons. RESULTS: Of 382 participants, 57.9% were 21-29 years old and 60.1% had some college or higher education. 30.3% reported using both ENDS and tobacco cigarettes and 11.9% were current ENDS users. The majority of participants had adequate knowledge about the facts and safety of ENDS and there was no difference across three ENDS user status groups. ENDS users perceived significantly lower risk of ENDS and higher benefit of using ENDS to aid quitting tobacco smoking, compared to non-ENDS users. The majority of participants reported that their healthcare providers less frequently assessed ENDS use during their prenatal visits, compared to tobacco cigarette use. CONCLUSIONS: There is critical need for healthcare providers to increase the screening for ENDS use during pregnancy and promote awareness of risks and benefits of ENDS in pregnant women. PMID- 29588117 TI - Decomposition of the population attributable fraction for two exposures. AB - PURPOSE: The population attributable fraction (AF) is frequently used to quantify disease burden attributable to exposures. AF is interpreted as the fractional reduction of disease events that would occur if exposures were eliminated. This article aims to provide a decomposition of the overall AF for two exposures into AFs for each of two exposures and AF for their interaction, using potential outcomes framework. METHODS: We provide the decomposition formula with and without confounders. We discuss an estimation method using standard regression models. We also show that these AFs without confounders can be effectively visualized. RESULTS: By a numerical comparison, we show that our decomposition is different from a previous decomposition, which does not have a causal interpretation if confounding exists. We illustrate the proposed decomposition using a large prospective cohort study data. CONCLUSIONS: When the primary exposure cannot be modifiable, the interventional interpretation of AF is difficult. Even then, if there exists an interaction between the exposure and another modifiable exposure, our decomposition can show what extent of the effect of the primary exposure can be eliminated by intervening on the modifiable exposure. PMID- 29588118 TI - Monitoring the efficacy of infant hepatitis B vaccination and revaccination in 0- to 8-year-old children: Protective anti-HBs levels and cellular immune responses. AB - Vaccination against hepatitis B virus (HBV) is recommended worldwide. The aim of this study was to assess the efficacy of infant hepatitis B vaccination and revaccination in 0- to 8-year-old children in the context of protective anti-HBs levels and cellular immune responses. Using a random questionnaire survey, 1695 pre-school children were recruited as research subjects during January 2015 to June 2017. Blood samples were obtained to measure HBV serological markers as well as peripheral immunocytes. The children were divided into non-, low- and hyper- responsive groups (NR, LR, and HR) based on the vaccination efficacy. Additionally, the effect of revaccination on the NR group was evaluated at 1 month after completion of the vaccination course. Among a total of 1695 children, 1591 (93.86%) were infants who were followed while undergoing their primary course of hepatitis B vaccination at the 0-1-6 month schedule, and 1249 (79.30%) of them developed antibodies against HBsAg (anti-HBs) titers greater than 10 IU/L. The results of immunocyte studies indicated that the CD8+ T cells, CD4+CD45RO+ T cells, CD8+CD45RA+ T cells, and T follicular helper (Tfh) cells increased significantly in NR compared with HR. However, lymphocytes, CD4+ T cells, and CD4+CD45RA+ T cells in NR were lower than that in HR. 96 of the non response cases showed seroprotection after revaccination among 103 cases. Therefore, most of the preschool children who received hepatitis B vaccine in infancy achieved significant seroprotection. Seroconversion rates of individuals revaccinated after initial vaccination failure were significantly higher than those after primary vaccination. Different vaccination efficacy groups showed significant changes in circulating immunocytes, which might be a factor affecting the recombinant HBV vaccine's immune effectiveness. PMID- 29588119 TI - Improving the immunogenicity and protective efficacy of the EtMIC2 protein against Eimeria tenella infection through random mutagenesis. AB - In recent years, directed evolution has emerged as an efficient tool to develop and identify novel protein variants. Eimeria tenella microneme-2 (EtMIC2) is a promising vaccine candidate for use against E. tenella infection; however, it only yields partial protection. The present study aimed to improve the immunogenicity and protective efficacy of EtMIC2 through random mutagenesis. Mutagenesis gene libraries of EtMIC2 were generated using error-prone polymerase chain reaction (epPCR), and the corresponding variant proteins were displayed on the yeast cell surface. Variant EtMIC2 proteins with high immunogenicity were screened through fluorescence-activated cell sorting (FACS) based on the affinity between polyclonal antibodies and antigens. Seven effective variant proteins were screened out and heterogeneously expressed in Escherichia coli as subunit vaccines. The protective efficacy of the variant proteins against E. tenella infections was then evaluated in chicken. Two variant proteins (1130 and 2119) displayed higher immunogenicity and protective efficacy than the wild-type EtMIC2 protein against E. tenella infections, increasing body weight gains and significantly decreasing lesion scores and fecal oocyst shedding, and increasing sIgA antibody production and lymphocyte proliferation. These variants displayed potential for use in the development of subunit vaccines for coccidiosis in chickens. The present results also indicate that directed evolution technology is useful for improving the immunogenicity and protective efficacy of parasite antigens. PMID- 29588121 TI - Large Metal Heads and Highly Cross-Linked Polyethylene Provide Low Wear and Complications at 5-13 Years. AB - BACKGROUND: Highly cross-linked polyethylene (XLPE) is reported to have low rates of linear and volumetric wear at 10-14 years. In a prior study, larger (36 and 40 mm) femoral heads were associated with more volumetric wear, but there were only 12 hips with these heads. METHODS: We evaluated 107 hips (93 patients, with a mean age of 76 years) with one design of uncemented acetabular component, a 36 (90 hips) or 40 mm (17 hips) metal femoral head, and one electron beam 100 kGy irradiated and remelted XLPE at a mean follow-up of 8 years (range 5-13 years). Selection of these femoral heads was based on several factors, including the perceived risk of dislocation, the outer diameter size of the acetabular component, and liner availability. Measurements of linear and volumetric wear were performed in one experienced laboratory by the Martell method and analyzed using the first-to-last method. Standard radiographs, with additional Judet views, were used to detect periprosthetic osteolysis. Clinical records were used to determine the complications of dislocation, liner fracture, and painful trunnion corrosion. RESULTS: For the entire cohort, the median linear wear rate was 0.041 mm/y (95% confidence interval, 0.031-0.057) and the median volumetric wear rate was 34.6 mm3/y (95% confidence interval, 31.4-53.5). With the numbers available, there was no difference in linear or volumetric wear between the 36 and 40 mm head sizes. Small, asymptomatic osteolytic lesions were noted in 3 hips (2%). There were 3 patients (3%) with dislocation (2 early and 1 late), but these have not had a revision. There were no revisions for loosening, no liner fracture, and no patient with symptomatic trunnion corrosion. CONCLUSION: This acetabular component and XLPE with large metal heads had low rates of linear and volumetric wear. Large metal femoral heads did not lead to liner fracture, loosening, or symptomatic trunnion corrosion in this patient population. However, we recommend longer clinical follow-up studies and caution in the routine use of larger metal femoral heads in other, younger patient populations. PMID- 29588120 TI - Pediatric hospitalizations attributable to rotavirus gastroenteritis among Cambodian children: Seven years of active surveillance, 2010-2016. AB - BACKGROUND: Each year, approximately 1,066 Cambodian children under five years old die of diarrhea, and 51% of these deaths are due to rotavirus gastroenteritis. Quantifying childhood hospitalizations caused by severe rotavirus infections is also important in demonstrating disease burden caused by this virus. The objective of this study is to update and confirm the current burden of pediatric hospitalizations attributable to rotavirus gastroenteritis among Cambodian children using seven years of continuous active, prospective surveillance from 2010 to 2016. We also characterize the circulating rotavirus genotypic strains during this period. METHODS: Active surveillance for rotavirus gastroenteritis was conducted from January 2010 through December 2016 at a national hospital in Phnom Penh, Cambodia. Children <60 months of age who were hospitalized for acute gastroenteritis (AGE) were consented and enrolled. Information on gender, age, clinical characteristics, and month of onset were collected. Stool specimens were collected and tested by enzyme immunoassay for the presence of rotavirus antigen, and genotyping was performed on rotavirus test positive specimens to characterize predominant rotavirus strains during the surveillance period. RESULTS: Of 7007 children enrolled with AGE and having specimens collected, 3473 (50%) were attributed to rotavirus gastroenteritis. The majority of rotavirus hospitalizations occurred in children younger than two years old (92%). Year-round rotavirus transmission was observed, with seasonal peaks during the cooler, dry months between November and May. Genotypic trends in rotavirus were observed over the surveillance period; the predominant rotavirus strains changed from G1P[8] (2010-2012), to G2P[4] (2013-2014), the emergence of genotype G8P[8] in 2015, and G3P[8] in 2016. CONCLUSIONS: Rotavirus is the leading cause of severe acute gastroenteritis hospitalizations in Cambodian children under five years old, with 50% of such hospitalizations attributable to rotavirus. Over 90% of rotavirus hospitalizations occurred in children under 2 years of age. Changes in the predominant rotavirus strains occurred over time among these unvaccinated children. This information is important to understand and prioritize the current potential impacts upon child health that could be achieved through the introduction of rotavirus vaccines in Cambodia. PMID- 29588122 TI - Autologous Impaction Bone Grafting for Bone Defects of the Medial Tibia Plateau During Primary Total Knee Arthroplasty: Propensity Score Matched Analysis With a Minimum of 7-Year Follow-Up. AB - BACKGROUND: The aims of this study were to (1) describe a novel technique for appropriate treatment of bone defects in medial tibial plateau grafted with autologous resected bone and (2) compare clinical outcomes, radiographic results, and survivorship of these knees with those of standard total knee arthroplasty (TKA) without bone defect. METHODS: We retrospectively reviewed 50 cases of primary TKA involving bone defects of medial tibial plateau managed with bone grafting for a minimum follow-up of 7 years. Autologous resected bones were used for bone graft after removing solid cortical bones at the defect site. After bone graft group was completed, one-to-one patient-matched control was accomplished based on propensity score matching of 50 knees. Survivorship was analyzed using the Kaplan-Meier method. The endpoint of survival was revision of implant. Clinical outcomes were also assessed including Knee Society Score and Western Ontario and McMaster Universities Osteoarthritis Index score. RESULTS: The mean follow-up was 117 months in the group with bone graft and 108 months in the group without bone graft. There were no significant differences in postoperative clinical scores and knee alignment. Nonprogressive radiolucent lines measuring <2 mm were observed in 8 knees in the group with bone graft and 9 knees in the group without bone graft. During the follow-up period, 1 patient with late infection underwent 2-stage revision and another revision for tibial loosening occurred in both groups. The 10-year cumulative survival rate for revision was 96.0% in both groups. CONCLUSION: Our technique of management of medial tibial bone defect using autologous bone graft yielded desirable results based on survival rate and clinical outcome. PMID- 29588123 TI - Home Health Services Are Not Required for Select Total Hip Arthroplasty Candidates: Assessment and Supplementation With an Electronic Recovery Application. AB - BACKGROUND: At our institution, all postoperative total hip arthroplasty (THA) candidates have received home health services (HHS), consisting of visiting nurses, physical and occupational therapists. However, with a more technologically inclined patient population, electronic patient rehabilitation applications (EPRAs) can be used to deliver perioperative care at the comfort of the patient's home. The aim of this study is to investigate the clinical utility and economic burden associated with digital rehabilitation applications in primary THA recipients. METHODS: We conducted a single-center, retrospective review of patients operated between November 2016 and November 2017. Before surgery, and at the discretion of the surgeon, patients were assigned to EPRA with HHS or EPRA alone. Patient baseline demographics, EPRA engagement, and validated patient-reported outcomes (PROs) were collected (Veterans Rand 12-Item Health Survey [VR-12] and Hip Disability and Osteoarthritis Outcome Score Junior) at baseline and 12 weeks. These PRO scores were correlated with cohort assignments to assess noninferiority of EPRA alone. RESULTS: In total, 268 patients received either EPRA-HHS (n = 169) or EPRA (n = 99) alone. Patients receiving EPRA only were on average younger (60.8 vs 65.8; P < .0001), but otherwise similar to patients in the EPRA-HHS cohort. EPRA-only patients demonstrated no differences in VR-12 (P > .05) and Hip Disability and Osteoarthritis Outcome Score Junior (P > .05) when compared with EPRA-HHS. CONCLUSION: The integration of electronic rehabilitation tools is gaining acceptance within the orthopedic community. Our study demonstrated that EPRA alone was clinically noninferior while substantially less costly than EPRA-HHS. PMID- 29588124 TI - Connectivity of the precuneus-posterior cingulate cortex with the anterior cingulate cortex-medial prefrontal cortex differs consistently between control subjects and first-episode psychosis patients during a movie stimulus. AB - BACKGROUND: Functional connectivity is altered in psychotic disorders. Multiple findings concentrate on the default mode network, anchored on the precuneus posterior cingulate cortex (PC-PCC). However, the nature of the alterations varies between studies and connectivity alterations have not been studied during an ecologically valid natural stimulus. In the present study, we investigated the functional and structural connectivity of a PC-PCC region, where functioning differentiated first-episode psychosis patients from control subjects during free viewing of a movie in our earlier study. METHODS: 14 first-episode psychosis patients and 12 control subjects were imaged with GE 3T, and 29 patients and 19 control subjects were imaged with a Siemens Skyra 3T scanner while watching scenes from the movie Alice in Wonderland. Group differences in functional connectivity were analysed for both scanners separately and results were compared to identify any overlap. Diffusion tensor measures of 26 patients and 19 control subjects were compared for the related white matter tracts, identified by deterministic tractography. RESULTS: Functional connectivity was increased in patients across scanners between the midline regions of the PC-PCC and the anterior cingulate cortex-medial prefrontal cortex (ACC-mPFC). We found no group differences in any of the diffusion tensor imaging measures. CONCLUSIONS: Already in the early stages of psychosis functional connectivity between the midline structures of the PC-PCC and the ACC-mPFC is consistently increased during naturalistic stimulus.

PMID- 29588126 TI - Effects of 12-month, double-blind N-acetyl cysteine on symptoms, cognition and brain morphology in early phase schizophrenia spectrum disorders. AB - BACKGROUND: Currently approved medications for schizophrenia are relatively ineffective for negative symptoms and cognitive impairment. N-Acetyl Cysteine (NAC) is a neuroprotective agent that improved general symptoms, cognitive impairment and negative symptoms in some but not all studies, but failed to improve positive symptoms in patients with schizophrenia. Progressive brain mass loss (PBML) has been consistently observed in early phase schizophrenia. NAC mitigates the deleterious effects oxidative stress, inflammation and glutamatergic excitotoxicity and these three pathological processes are hypothesized to contribute to PBML. METHODS: In this study, we assessed the effects NAC (3600mg/day) in a 52-week, double-blind, placebo controlled trial on symptoms, and cognition in early phase schizophrenia spectrum disorders (N=60). In the context of the clinical trial, we explored the effects of NAC on brain morphology. RESULTS: NAC significantly improved (time*group) PANSS total (F=14.7, p<0.001), negative (F=5.1, p=0.024) and disorganized thought (F=13.7, p<0.001) symptom scores. NAC failed to improve PANSS positive symptoms and BACS cognitive scores. In preliminary analyses, baseline right (r=-0.48, p=0.041) and left (r= 0.45, p=0.018) total cortical thickness, and thickness in other cortical regions, were associated with NAC related improvement in PANSS total scores, but NAC, as compared to placebo, did not significantly impact brain morphology over the study treatment period. CONCLUSIONS: These results replicate some but not all previous findings of NAC efficacy. Preliminary results suggest that NAC's symptom effects may be related to structural integrity, but NAC failed to demonstrate treatment effects on longitudinal measures of brain morphology. ClinicalTrials.gov Identifier: NCT01339858. PMID- 29588127 TI - Severity of pain is associated with insufficient energy coverage in hospitalised patients: A cross-sectional study. AB - BACKGROUND & AIMS: The severity of pain is routinely assessed in hospitalised patients but the impact of pain and pain control on energy coverage has been poorly studied. This One-day cross-sectional observational study assessed the association between severity of pain and coverage of energy needs in hospitalised patients. METHODS: Foods provided and consumed were assessed on one day by dedicated dieticians for unselected hospitalised patients receiving three meals per day. Severity of pain was evaluated by a visual analogue scale at the mealtimes, averaged over the study day, and categorized as no pain, slight, moderate or severe pain. The coverage of energy needs was expressed in percentage of predicted needs. RESULTS: Among the 755 included patients, 63% reported having pain. Severe pain was associated with a lower energy coverage than no pain (p = 0.001) or slight pain (p = 0.001). Insufficient energy coverage, defined as <=70% of predicted needs, occurred in 13% of the patients. In univariate logistic regressions, predictors of insufficient energy coverage were severe pain as compared to no pain (OR 2.38; 95% CI 1.21, 4.64) and treatment with opioid drugs as compared to no pain killer (OR 1.73; 95% CI 1.07, 2.79). When including sex, age, body mass index, treatment with analgesics and severity of pain in a multivariate logistic regression, severe pain more than doubled the risk of insufficient energy coverage (OR 2.32; CI 1.15, 4.66). CONCLUSIONS: Patients experiencing severe pain have a high risk of insufficient energy coverage. Optimal pain control is probably critical to prevent underfeeding in the hospital.

PMID- 29588128 TI - Design, synthesis, and functional assessment of Cmpd-15 derivatives as negative allosteric modulators for the beta2-adrenergic receptor. AB - The beta2-adrenergic receptor (beta2AR), a G protein-coupled receptor, is an important therapeutic target. We recently described Cmpd-15, the first small molecule negative allosteric modulator (NAM) for the beta2AR. Herein we report in details the design, synthesis and structure-activity relationships (SAR) of seven Cmpd-15 derivatives. Furthermore, we provide in a dose-response paradigm, the details of the effects of these derivatives in modulating agonist-induced beta2AR activities (G-protein-mediated cAMP production and beta-arrestin recruitment to the receptor) as well as the binding affinity of an orthosteric agonist in radio ligand competition binding assay. Our results show that some modifications, including removal of the formamide group in the para-formamido phenylalanine region and bromine in the meta-bromobenzyl methylbenzamide region caused dramatic reduction in the functional activity of Cmpd-15. These SAR results provide valuable insights into the mechanism of action of the NAM Cmpd-15 as well as the basis for future development of more potent and selective modulators for the beta2AR based on the chemical scaffold of Cmpd-15.

AB - OBJECTIVES: To assess protective effects of micronized purified flavonoid fraction (MPFF) on microcirculation in an original chronic model of hind limb venous hypertension with low blood flow in small animals. METHODS: Vein ligatures were performed on male hamsters, as follows: A-right femoral vein; A + B-right femoral vein and its right branch; A + C-right femoral vein and its left branch; A + B + C-right femoral and its right and left branches; D-external right iliac vein. In sham operated groups, similar vascular dissections were performed without ligatures. Superficial (epigastric) and central (jugular) venous pressure evaluations were made during a 10 week period. Hamsters subjected to A + B + C and D ligatures were selected for leukocyte rolling and sticking, functional capillary density (FCD), and venular and arteriolar diameter observations. D ligature was selected to evaluate pharmacological treatment efficacy. MPFF (100 mg/kg), concomitant active flavonoids of MPFF (diosmetin, hesperidin, linarin, and isorhoifolin) (10 mg/kg), diosmin (100 mg/kg) or drug vehicle were administered orally during 2 weeks before vein ligature and 6 weeks thereafter. RESULTS: A, A + B and A + C models maintained venous return through collaterals. From the 2nd to the 10th weeks after vein ligatures, A + B + C and D models elicited a progressive increase of superficial venous pressure (3.83 +/- 0.65 vs. 8.56 +/- 0.72 mmHg, p < .001 and 4.13 +/- 0.65 vs. 9.35 +/- 0.65 mmHg, p < .001, respectively) with significant changes to the microcirculation. As D model significantly increased superficial venous pressure without affecting central venous pressure, it was used to evaluate the long-term effects of treatment. Compared with vehicle, MPFF, concomitant active flavonoids of MPFF, and diosmin, significantly decreased leukocyte-endothelium interaction and prevented FCD reduction. Only MPFF significantly prevented venular enlargement as observed in the vehicle treated group. CONCLUSION: MPFF was more effective than diosmin in improving all microvascular variables. The superiority of MPFF over diosmin alone can be explained by the synergistic beneficial effects of the association between diosmin and active flavonoids of MPFF. PMID- 29588129 TI - Endoplasmic Reticulum-Mitochondrial Contactology: Structure and Signaling Functions. AB - Interorganellar contacts are increasingly recognized as central to the control of cellular behavior. These contacts, which typically involve a small fraction of the endomembrane surface, are local communication hubs that resemble synapses. We propose the term contactology to denote the analysis of interorganellar contacts. Endoplasmic reticulum (ER) contacts with mitochondria were recognized several decades ago; major roles in ion and lipid transfer, signaling, and membrane dynamics have been established, while others continue to emerge. The functional diversity of ER-mitochondrial (ER-mito) contacts is mirrored in their structural heterogeneity, with subspecialization likely supported by multiple, different linker-forming protein structures. The nanoscale size of the contacts has made studying their structure, function, and dynamics difficult. This review focuses on the structure of the ER-mito contacts, methods for studying them, and the roles of contacts in Ca2+ and reactive oxygen species (ROS) signaling. PMID- 29588132 TI - Epidemiology of lower extremity peripheral artery disease in veterans. AB - OBJECTIVE: The objective of this study was to describe the epidemiology, clinical features, outcomes, and predictors of mortality in veterans with peripheral artery disease (PAD). METHODS: We used national data from the Veterans Health Administration from fiscal years 2009 to 2011 to identify patients with a new diagnosis of PAD. Within this cohort, we describe characteristics of the patients, use of recommended medications, and clinical outcomes during a 3-year follow-up (fiscal year 2014). We used Cox proportional hazards regression to examine predictors of mortality and adverse limb outcomes (amputation and hospitalization for critical limb ischemia [CLI]) during follow-up. RESULTS: A total of 175,865 patients with a new diagnosis of PAD were included. The mean age was 69.9 years; 97.8% were male, and 67.7% were white. Nearly 77% of patients had hypertension, 46.5% had diabetes, 23% had chronic obstructive pulmonary disease, and 12.9% had renal failure. A prescription for statins was filled by 60.8%, and 34.9% received high-intensity statins within 90 days of PAD diagnosis. At 1 year, 2.6% underwent revascularization, 1.3% developed CLI, and 1.1% underwent amputation. During a median follow-up of 3.8 years, a total of 28.6% patients died (6.7% at 1 year), and 3.7% developed a limb outcome (2.0% at 1 year). Predictors of mortality included advanced age, comorbidities, and CLI or amputation at presentation. In contrast, prescription with statins was associated with lower mortality. Similar findings were present with regard to predictors of adverse limb outcomes, except that older age was associated with a lower risk of amputation or CLI. CONCLUSIONS: We found that veterans with PAD have a high prevalence of comorbid conditions and have a significant risk of mortality and limb loss. A substantial proportion of veterans with PAD are not prescribed recommended medications, especially statin therapy. Our data highlight important opportunities for improving care of veterans with PAD. PMID- 29588134 TI - Cardioprotective effect of cerium oxide nanoparticles in monocrotaline rat model of pulmonary hypertension: A possible implication of endothelin-1. AB - AIMS: Cerium oxide nanoparticles (CeO2NPs) have been recently introduced into the medical field for their antioxidant properties. The ability of CeO2NPs alone or in combination with spironolactone (SP) to attenuate monocrotaline (MCT)-induced pulmonary hypertension and associated right ventricular hypertrophy was studied in rats. A special emphasis was given to endothelin-1 pathway. MATERIALS AND METHODS: Pulmonary hypertension was induced in albino rats by a single subcutaneous injection of MCT (60 mg/kg). Rats received either single CeO2NPs therapy or combined therapy with SP for 2 weeks. KEY FINDINGS: CeO2NPs improved pulmonary function tests with concomitant decrease in serum endothelin-1 and pulmonary expression of endothelin-1 and its receptor ETAR. Besides, CeO2NPs diminished MCT-induced right ventricular hypertrophy and reduced cardiac oxidative stress and apoptosis. SIGNIFICANCE: CeO2NPs could improve pulmonary hypertension and associated right ventricular hypertrophy with no additive value for SP. Besides being an antioxidant, CeO2NPs work through endothelin-1 pathway to improve pulmonary hypertension. PMID- 29588133 TI - The association of comorbid depression with mortality and amputation in veterans with peripheral artery disease. AB - OBJECTIVE: Peripheral artery disease (PAD) is an increasing health concern with rising incidence globally. Previous studies have shown an association between PAD incidence and depression. The objective of the study was to determine the association of comorbid depression with PAD outcomes (amputation and all-cause mortality rates) in veterans. METHODS: An observational retrospective cohort of 155,647 patients with incident PAD (2003-2014) from nationwide U.S. Veterans Health Administration hospitals was conducted using the national Veterans Affairs Corporate Data Warehouse. Depression was measured using concurrent International Classification of Diseases, Ninth Revision diagnosis codes 6 months before or after PAD diagnosis. The main outcomes were incident major amputation and all cause mortality. Crude associations were assessed with Kaplan-Meier plots. The effects of depression adjusted for covariates were analyzed using Cox proportional hazards models. RESULTS: Depression was present in 16% of the cohort, with the occurrence of 9517 amputations and 63,287 deaths (median follow up, 5.9 years). Unadjusted hazard ratios (HRs) of comorbid depression for amputations and all-cause mortality were 1.32 (95% confidence interval [CI], 1.25 1.39) and 1.02 (95% CI, 0.99-1.04), respectively. After adjustment for covariates in Cox regression models, a diagnosis of comorbid depression at the time of PAD diagnosis was associated with a 13% higher amputation (HR, 1.13; 95% CI, 1.07 1.19) and 17% higher mortality (HR, 1.17; 95% CI, 1.14-1.20) risk compared with patients with no depression. On stratification by use of antidepressants, depressed patients not taking antidepressants had a 42% higher risk of amputation (HR, 1.42; 95% CI, 1.27-1.58) compared with those without depression. Patients taking antidepressants for depression still had increased risk of amputation but only 10% higher compared with those without depression (HR, 1.10; 95% CI, 1.03 1.17). Interestingly, patients taking antidepressants for other indications also had a higher risk of amputation compared with those not having depression or not taking antidepressants (HR, 1.08; 95% CI, 1.03-1.14). Having any diagnosis of depression or the need for antidepressants increased the mortality risk by 18% to 25% in the PAD cohort compared with those without depression and not taking antidepressants for any other indication. CONCLUSIONS: PAD patients with comorbid depression have a significantly higher risk of amputation and mortality than PAD patients without depression. Furthermore, untreated depression was associated with an increased amputation risk in the PAD population, more so than depression or other mental illness being treated by antidepressants. The underlying mechanisms for causality, if any, remain to be determined. The association of antidepressant treatment use with amputation risk should prompt further investigations into possible mechanistic links between untreated depression and vascular dysfunction.

AB - BACKGROUND: Low serum vitamin D has been associated with metabolic syndrome and Non-alcoholic fatty liver disease (NAFLD). This study aimed to investigate the impact of vitamin D supplementation in treatment of patients with NAFLD. METHODS: In a double blind, randomized, placebo controlled trial patients with NAFLD were randomized to receive one weekly pearl of placebo, 50,000 U vitamin D3 (cholecalciferol) pearl per week and 0.25 mg calcitriol (1,25 dihydroxycholecalciferol) pearl per day for 3 months. RESULTS: 106 NAFLD patients were randomized to receive calcitriol, vitamin D3 and placebo pearls for 12 weeks and data for 91 patients were analyzed. After 12 weeks of treatment, serum alkaline phosphatase levels was significantly decreased from baseline levels in vitamin D and calcitriol treated groups (P < 0.05). Serum and gamma glutamyl transferase (GGT) level was also significantly decreased compared to the baseline levels after 12 weeks of treatment with vitamin D. There was no statistically significant difference between placebo, calcitriol, vitamin D groups in terms of serum aminotransferase, alkaline phosphatase, serum GGT and lipid profile (P > 0.05). CONCLUSION: While significant reduction of serum alkaline phosphatase and GGT were seen with vitamin D and calcitriol supplementation from baseline levels, no beneficial effects was seen when comparing vitamin D, calcitriol and placebo groups at the end of trial. PMID- 29588138 TI - Effect of Eicosapentaenoic acid (EPA) supplementation on cardiovascular markers in patients with type 2 diabetes mellitus: A randomized, double-blind, placebo controlled trial. AB - AIMS: Cardiovascular complications are one of main cause of increased mortality and morbidity among Diabetes Mellitus (DM) patients. Altered metabolism of sulphur amino acids in diabetes reflected as increases in concentration of methionine and cysteine/cystine in the blood which known as a markers of Cardiovascular Diseases (CVD). The aim of present study was to determine the effect of Eicosapentaenoic acid (EPA) supplementation on sulfhydryl amino acids and Atherogenic Index of Plasma (AIP) in patients with type 2 DM (T2DM). METHOD: A randomized, double-blind, placebo-controlled clinical trial was performed in 36 control and patients with DM. The subjects were randomly assigned to obtain 2 g/d EPA (n = 18) or placebo (n = 18) for 8 weeks. Fasting serum level of Cystein and Methionine were measured using HPLC method and atherogenic index of plasma (AIP) as a proxy measure of atherosclerosis was computed. RESULTS: Eight weeks supplementation with EPA led to significant reductions in Met (p < 0.002) and Cys (p < 0.001) compared with the placebo (p < 0.06). In addition, compared to placebo a significant reduction in AIP were seen after taking EPA (p < 0.04). CONCLUSION: EPA supplementation in patients with T2DM for eight weeks had beneficial effects on Met, Cys and AIP, which may attribute to the prevention of vascular complications in the T2DM patients.

PMID- 29588140 TI - Cochlear implant function in a patient with Jervell and Lange-Nielsen syndrome after defibrillation by countershock. AB - Jervell and Lange-Nielsen syndrome (JLNS), a rare autosomal recessive congenital QT prolongation syndrome, is characterized by cardiac arrhythmias, syncopal episodes, and profound deafness. A cochlear implant (CI) for patients with JLNS is expected to result in hearing improvement. Sometimes, defibrillation is required if a patient experiences lethal arrhythmia. In this paper, we report a pediatric patient with JLNS who received defibrillation after CI surgery in his right ear at the age of 2 years. With intensive care, the post-operative course was uneventful, and the patient acquired satisfactory speech and hearing abilities. Five years after the surgery, he underwent defibrillation because of the incidence of syncopal attack. Thereafter, arrhythmic syncope recurred three times, which necessitated defibrillation therapy. To prevent recurrence of cardiac arrhythmia, he underwent ICD (implantable cardioverter-defibrillator) implantation at the age of 11 years. At present, CI works well and provides good hearing, while syncopal attack is prevented by ICD. From the experience of this case, electronic circuit of CI is thought to tolerate emergency countershock if the speech processor is removed. PMID- 29588141 TI - Random walks on binary strings applied to the somatic hypermutation of B-cells. AB - Within the germinal center in follicles, B-cells proliferate, mutate and differentiate, while being submitted to a powerful selection: a micro evolutionary mechanism at the heart of adaptive immunity. A new foreign pathogen is confronted to our immune system, the mutation mechanism that allows B-cells to adapt to it is called somatic hypermutation: a programmed process of mutation affecting B-cell receptors at extremely high rate. By considering random walks on graphs, we introduce and analyze a simplified mathematical model in order to understand this extremely efficient learning process. The structure of the graph reflects the choice of the mutation rule. We focus on the impact of this choice on typical time-scales of the graphs' exploration. We derive explicit formulas to evaluate the expected hitting time to cover a given Hamming distance on the graphs under consideration. This characterizes the efficiency of these processes in driving antibody affinity maturation. In a further step we present a biologically more involved model and discuss its numerical outputs within our mathematical framework. We provide as well limitations and possible extensions of our approach. PMID- 29588142 TI - Diffusion-weighted magnetic resonance imaging is more sensitive than dimercaptosuccinic acid scintigraphy in detecting parenchymal lesions in children with acute pyelonephritis: A prospective study. AB - INTRODUCTION: Static renal scintigraphy is the gold standard for detection of inflammatory changes in the renal parenchyma in acute pyelonephritis. Our aim was to determine whether diffusion-weighted magnetic resonance imaging (DW-MRI) was comparable with static renal scintigraphy (DMSA-SRS) to demonstrate acute renal parenchymal lesions. OBJECTIVE: To compare 99mTc-dimercaptosuccinic acid static renal scintigraphy (DMSA-SRS) with diffusion-weighted magnetic resonance imaging (DW-MRI) for detecting acute inflammatory changes in the renal parenchyma in children with febrile urinary tract infection. METHODS: Thirty-one children (30 girls) aged 3-18 years with a first episode of febrile UTI without a previously detected congenital malformation of the urinary tract, were prospectively included. DMSA-SRS and DW-MRI were performed within 5 days of diagnosis to detect renal inflammatory lesions. The DW-MRI examination was performed without contrast agent and without general anesthesia. Late examinations were performed after 6 months using both methods to detect late lesions. RESULTS: DW-MRI confirmed acute inflammatory changes of the renal parenchyma in all 31 patients (100%), mostly unilateral. DMSA-SRS detected inflammatory lesions in 22 children (71%; p = 0.002). The lesions were multiple in 26/31 children (84%) on DW-MRI and in 9/22 (40%) on DMSA-SRS. At the control examination, scarring of the renal parenchyma was found equally by DW-MRI and DMSA-SRS in five patients (16%), three of whom were the same patients. The overall concordance of positive and negative late findings occurred in 87% of patients. There was correspondence in the anatomical location of acute and late lesions. DISCUSSION: The clinical significance of acute and late parenchymal findings on DWI-MR is yet to be determined. A limitation of our study is the age of the patients (older than 3 years) who are less sensitive to scar development; therefore, a smaller number of patients with scars could be analyzed during control examination. Further studies using the DW MRI should confirm its reliability to detect acute and late lesions in younger children and infants and determine the clinical consequences. CONCLUSION: DW-MRI has higher sensitivity for detecting acute renal inflammatory lesions and multifocal lesions than DMSA-SRS. The incidence of scars was low and corresponded with the anatomical location of acute and late lesions. PMID- 29588143 TI - Vascular thrombosis in pediatric kidney transplantation: Graft survival is possible with adequate management. AB - OBJECTIVE: Vascular thrombosis (VT) in pediatric kidney transplantation (KT) is a dreaded event that leads to graft loss in almost 100% of cases. In recent years, VT has become the most common cause of early graft loss. The aim of this study was to analyze our experience in diagnosis and treatment of VT and the impact of a new management protocol on patient outcome. METHODS: We conducted a retrospective study of 176 consecutive KT performed at our institution by the pediatric urology team between January 2000 and December 2015 and identified patients with VT. A protocol of prevention and early detection of VT was introduced in 2012. RESULTS: Out of 176 KT, nine cases of VT were identified (5.1%). The mean recipient age was 5.1 years (SD 4.9 years) and mean weight was 22.28 kg (SD 15.6 kg). Diagnosis was intraoperative in two cases and within the first 24 h after surgery in the remaining seven. Immediate surgical exploration was performed after diagnosis in all. Of the five episodes that occurred before 2012, all developed complete graft ischemia requiring transplantectomy. However, in the four cases diagnosed after 2012, graft perfusion could be restored in three, and abdominal wall closure with a mesh and delayed sequentially closure under ultrasound guidance was performed. With a follow-up of 30, 25, and 20 months, the three recovered grafts are still functioning normally. CONCLUSIONS: Increased awareness and the application of a protocol for prevention, detection and treatment of VT in pediatric KT can prevent graft loss. Immediate surgical intervention is mandatory after diagnosis. Avoiding compartment syndrome with delayed sequential closure may be useful to improve graft survival.

PMID- 29588145 TI - Vitamin D deficiency and pre-eclampsia in Colombia: PREVitD study. AB - PURPOSE: Pre-eclampsia is a multisystem disorder characterized by new-onset hypertension and proteinuria during pregnancy. Pre-eclampsia remains a major cause of maternal death in low-income countries. Vitamin D has a very diverse biological role in cardiovascular diseases. This study will evaluate the association of vitamin D levels and relevance to pre-eclampsia. METHODS: We conducted a case-control study of women recruited from the GenPE (Genetics and Pre-eclampsia) Colombian registry. This is a multicenter case-control study conducted in eight Colombian cities. 25-Hydroxyvitamin D (25(OH)D) concentration was measured using liquid-chromatography-tandem mass spectrometry from 1013 women with pre-eclampsia and 1015 mothers without pre-eclampsia (controls). RESULTS: Fifty-two percent of women with pre-eclampsia were vitamin D deficient. The 25(OH)D concentrations were significantly lower in the pre-eclampsia (mean 29.99 ng/mL; 95% CI: 29.40-30.58 ng/mL) group compared to controls (mean 33.7 ng/mL; 95% CI: 33.20-34.30 ng/mL). In the unadjusted model, maternal vitamin D deficiency, defined by maternal 25(OH)D concentration <30 ng/mL, was associated with an increased probability of suffering from pre-eclampsia (OR 2.10; 95% CI, 1.75-2.51). After adjusting for covariates, a similarly increased probability of having pre-eclampsia was observed (OR 2.18; 95% CI, 1.80-2.64) among women with vitamin D deficiency, relative to controls. CONCLUSION: Although the results suggest that low maternal concentrations of 25(OH)D increase pre-eclampsia risk, this evidence may not be indicative of a causal association. Future studies are needed to confirm a definite causal relationship between concentrations of vitamin D and the risk of pre-eclampsia, by means of powered clinical trials.

Here we report a patient who sustained spontaneous chordae tendineae rupture complicated with severe mitral regurgitation and acute pulmonary edema during peripartum period. Probable causes of chordae tendineae rupture include mitral valve prolapse, infectious endocarditis, congenital heart disease, rheumatic heart disease, ischemic heart disease, connective tissue diseases, previous mitral valve surgery or pregnancy itself. The pathophysiology of spontaneous chordae tendineae rupture due to pregnancy remains unclear. However, certain physiological stress, including hormone changes related matrix remodeling, increased cardiac output during pregnancy or labor pain may precipitate to this condition. Literature reviews from previously reported cases showed that those who were diagnosed chordae tendineae rupture at very preterm period all had preterm delivery.

PMID- 29588151 TI - Strength of the lower limb and trunk muscles is associated with gait speed in individuals with sub-acute stroke: a cross-sectional study. AB - OBJECTIVES: To investigate the association between measures of strength of the lower limb and trunk muscles and gait speed and to identify the muscle group that would best predict gait speed in individuals with sub-acute stroke. METHODS: Using a cross-sectional observational study design, forty-four individuals with sub-acute stroke (62 years, SD=14; 4 months, SD=1 post-stroke) were assessed. The evaluations were performed at a university laboratory, participants' homes, or community-based settings. Bilateral maximum isometric strength (hip, knee, and ankle flexors/extensors, hip abductors, trunk flexors/extensors, and trunk lateral flexors and rotators) was measured using a portable dynamometer. Comfortable and maximum gait speeds were measured using the 10-m walk test. RESULTS: Weak to moderate associations were found between measures of strength of the lower limb muscles and comfortable (0.36<=r<=0.53; p<0.05) and maximum (0.37<=r<=0.59; p<0.05) gait speeds, except for the non-paretic knee flexors and comfortable gait speed (p=0.06). Weak to moderate associations were also found between measures of strength of the trunk muscles and comfortable (0.39<=r<=0.50; p<0.05) and maximum (0.39<=r<=0.61; p<0.05) gait speeds. Stepwise multiple regression analyses revealed that the non-paretic dorsiflexors and the left lateral trunk flexors explained 29% and 42% of the variance in the maximum and comfortable gait speeds, respectively. CONCLUSIONS: The strength of the lower limb and trunk muscles was positively associated with comfortable and maximum gait speeds. The muscle strength of the non-paretic dorsiflexors and the left lateral trunk flexors might have a role to play in determining comfortable and maximum gait speeds of individuals with sub-acute stroke. PMID- 29588152 TI - Generation and characterization of a potent fully human monoclonal antibody against the interleukin-23 receptor. AB - Interleukin (IL)-12 and IL-23 share a common subunit (p40) and function in T helper (Th) 1 and Th17 immunity, respectively. Anti-IL-12/23p40 and specific anti IL-23 antibodies are currently in clinical use for psoriasis and undergoing trials for autoimmune diseases. Since expression levels of the IL-23 receptor are likely to be much lower than those of IL-23, an anti-IL-23 receptor antibody might offer greater promise in inhibiting the IL-23-IL-17 pathways involved in inflammatory disorders. To our knowledge, no anti-IL-23 receptor antibody has been trialed in clinical studies to date. This study describes the generation and characterization of AS2762900-00, a fully human monoclonal antibody against the IL-23 receptor. AS2762900-00 bound both human and cynomolgus monkey IL-23 receptors. AS2762900-00 showed potent inhibitory effects on IL-23-induced Kit-225 cell proliferation compared to the existing anti-IL-12/23p40 antibody, ustekinumab. In a single dose administration pharmacodynamics study in cynomolgus monkeys, 1 mg/kg of AS2762900-00 significantly inhibited (> 85%) IL-23-induced STAT3 phosphorylation in blood for up to 84 days. Therefore, AS2762900-00 represents a potent novel IL-23-IL-17 pathway inhibitor with the potential to be developed into a new therapy for the treatment of autoimmune diseases.

PMID- 29588153 TI - Furaltadone suppresses IgE-mediated allergic response through the inhibition of Lyn/Syk pathway in mast cells. AB - Mast cells are critical cells that prompt various allergic response-inducing factors, contributing to allergic diseases. While used as an antibiotic for livestock, there is no study on the effect of furaltadone on allergic response. This study investigated the effect of furaltadone on mast cells and passive cutaneous anaphylaxis (PCA). Furaltadone inhibited the degranulation of mast cells stimulated by antigen (IC50, ~ 3.9 MUM), and also suppressed the production of tumor necrosis factor (TNF)-alpha and interleukin (IL)-4 in a concentration dependent manner. In addition, furaltadone inhibited allergic responses in an acute allergy animal model, PCA. Further investigation on the mechanism for these inhibitory effects of furaltadone found that the activities of Lyn/Syk and Syk dependent downstream proteins such as mitogen-activated protein (MAP) kinases were inhibited by furaltadone in mast cells. Taken together, this study demonstrates that furaltadone inhibits the activation of mast cells by antigen via the suppression of the Lyn/Syk pathway and ameliorates allergic responses in vivo. PMID- 29588155 TI - Identification of Immunodominant Th2-Cell Epitopes in Chinese Patients with Bullous Pemphigoid. AB - Bullous pemphigoid (BP) is a subepidermal autoimmune blistering disease caused by autoantibodies targeting the juxtamembranous extracellular noncollagenous 16A (NC16A) domain of human collagen XVII (also known as BP180). Because T-helper (Th) cells are essential for antibody responses to antigens, we adopted an assay to map the immunodominant Th2-cell epitopes in NC16A. We synthesized 22 overlapping peptides spanning the entire sequence of BP180-NC16A and investigated the reactivity of Th2 cells from patients with BP to these peptides using the Enzyme-Linked ImmunoSpot (ELISPOT) assay. We screened two epitope peptides, P2 (492-506 aa: VRKLKARVDELERIR) and P5 (501-515 aa: ELERIRRSILPYGDS), and confirmed that these epitopes play a dominant role in stimulating CD4+ T-cell proliferation and Th2 IL-4 cytokine production, and activating B cells to secrete autoantibodies. These immunodominant epitopes are HLA-DR-restricted and were observed in subjects with different HLA alleles. This work contributes to elucidation of the epitope-mediated immunologic pathogenesis of BP, and the identified Th2-cell epitopes are candidates for epitope-specific therapeutic strategy. PMID- 29588156 TI - "Tumulus" stabilization of a total ossicular replacement prosthesis. AB - Functional failure of total ossicular replacement prostheses (TORP) is often due to secondary displacement, ranging from simple subluxation to prosthesis extrusion following recurrence of severe tympanic membrane retraction. Several surgical techniques have been proposed to stabilize a TORP, mostly using superimposed non-organic or resorbable heterologous materials. We describe a simple so-called "tumulus" surgical technique that limits prosthesis displacement and extrusion, regardless of the type of TORP, by using a few fragments of autologous cartilage that are always available and perfectly tolerated at no cost. Review of 31 cases treated by this technique did not reveal any cases of prosthesis displacement and only one case (3.2%) of prosthesis extrusion with audiometric results comparable to the best results reported in the literature.

AB - Parkinson's disease (PD) remains one of the most common neurodegenerative movement disorders with limited treatment options available. A dopamine derivative N-3,4-bis(pivaloyloxy)-dopamine (BPD) previously developed in our group has demonstrated superior therapeutic outcome compared to levodopa in a PD mice model. To further improve the therapeutic performance of BPD, a brain targeted drug delivery system was designed using a 29 amino-acid peptide (RVG29) derived from rabies virus glycoprotein as the targeting ligand. RVG29 functionalized liposomes (RVG29-lip) showed significantly higher uptake efficiency in murine brain endothelial cells and dopaminergic cells, and high penetration efficiency across the blood brain barrier (BBB) in vitro. In vivo and ex vivo distribution studies demonstrated RVG29-lip selectively distributed to the brain, striatum and substantia nigra. Furthermore, BPD loaded RVG29-lip (BPD RVG29-lip) exhibited improved therapeutic efficacy in a PD mouse model, while causing no obvious systemic toxicity after intravenous administration. Thus, BPD RVG29-lip represents a highly promising approach for the brain targeted treatment of PD. PMID- 29588157 TI - Gp2.5, the multifunctional bacteriophage T7 single-stranded DNA binding protein.

Multiple layers of macromolecular interactions mediate its function in replication, recombination, repair, and the maturation of viral genomes. In addition to binding ssDNA, the protein binds to DNA polymerase and DNA helicase, regulating their activities. The protein displays potent homologous DNA annealing activity, underscoring its role in recombination. PMID- 29588158 TI - Dynamics of E. coli single stranded DNA binding (SSB) protein-DNA complexes. AB - Single stranded DNA binding proteins (SSB) are essential to the cell as they stabilize transiently open single stranded DNA (ssDNA) intermediates, recruit appropriate DNA metabolism proteins, and coordinate fundamental processes such as replication, repair and recombination. Escherichia coli single stranded DNA binding protein (EcSSB) has long served as the prototype for the study of SSB function. The structure, functions, and DNA binding properties of EcSSB are well established: The protein is a stable homotetramer with each subunit possessing an N-terminal DNA binding core, a C-terminal protein-protein interaction tail, and an intervening intrinsically disordered linker (IDL). EcSSB wraps ssDNA in multiple DNA binding modes and can diffuse along DNA to remove secondary structures and remodel other protein-DNA complexes. This review provides an update on these features based on recent findings, with special emphasis on the functional and mechanistic relevance of the IDL and DNA binding modes. PMID- 29588160 TI - Role for primary immunosuppression with everolimus after pulmonary transplantation. PMID- 29588161 TI - Gene expression profiling scores in dual organ transplant patients are similar to those in heart-only recipients. AB - BACKGROUND: Serial gene expression profiling (GEP) may reduce the need for endomyocardial biopsies for detecting acute cellular rejection (ACR) after transplantation, but its performance in dual organ transplant recipients is currently unknown. METHODS: We analyzed 18 months of follow-up in a national cohort of 27 dual organ recipients (18 heart-kidney, 8 heart-liver, 1 heart-lung) matched to 54 heart-only recipients for gender, age, and time to first GEP (AlloMap(r)) test. ACR, antibody-mediated rejection (AMR), cytomegalovirus infections, biopsies, and longitudinal GEP scores were evaluated. RESULTS: During the first 90 days post-transplant, the mean GEP score for dual organ recipients was 25.2 +/- 9.1, vs. 23.5 +/- 7.7 for heart-only recipients (P = 0.48), with final GEP scores being 29.1 +/- 6.1 and 32.3 +/- 3.4, respectively (P = 0.34). GEP scores increased over time (P < 0.001) at a similar rate (P = 0.33) for both groups. One heart-only recipient had treated ACR (GEP score = 17). Fourteen subjects had cytomegalovirus infection, 8 of whom were dual-organ. During follow up, mean GEP score among patients with cytomegalovirus infection was 32.3, compared to 26.7 (p < 0.001) in patients without cytomegalovirus. Only 4 (2%) of 233 biopsies were positive for mild AMR; all occurring in 2 heart-only recipients (GEP scores = 18-33). CONCLUSIONS: This largest cohort to date suggests that dual organ transplantation alone should not be reason to omit GEP testing from post transplant medical management, as the two groups' scores did not differ significantly. Confirming that GEP scores increase over time for heart-only and dual organ recipients and in the presence of cytomegalovirus infection, our work shows promise for the use of serial GEP testing in dual organ recipients. PMID- 29588162 TI - Aminochrome decreases NGF, GDNF and induces neuroinflammation in organotypic midbrain slice cultures. AB - Recent evidence shows that aminochrome induces glial activation related to neuroinflammation. This dopamine derived molecule induces formation and stabilization of alpha-synuclein oligomers, mitochondria dysfunction, oxidative stress, dysfunction of proteasomal and lysosomal systems, endoplasmic reticulum stress and disruption of the microtubule network, but until now there has been no evidence of effects on production of cytokines and neurotrophic factors, that are mechanisms involved in neuronal loss in Parkinson's disease (PD). This study examines the potential role of aminochrome on the regulation of NGF, GDNF, TNF alpha and IL-1beta production and microglial activation in organotypic midbrain slice cultures from P8 - P9 Wistar rats. We demonstrated aminochrome (25 MUM, for 24 h) induced reduction of GFAP expression, reduction of NGF and GDNF mRNA levels, morphological changes in Iba1+ cells, and increase of both TNF-alpha, IL 1beta mRNA and protein levels. Moreover, aminochrome (25 MUM, for 48 h) induced morphological changes in the edge of slices and reduction of TH expression. These results demonstrate neuroinflammation, as well as negative regulation of neurotrophic factors (GDNF and NGF), may be involved in aminochrome-induced neurodegeneration, and they contribute to a better understanding of PD pathogenesis. PMID- 29588163 TI - The involvement of plasmacytoid cells in HIV infection and pathogenesis. AB - Plasmacytoid dendritic cells (pDCs) are a unique dendritic cell subset that are specialized in type I interferon (IFN) production. pDCs are key players in the antiviral immune response and serve as bridge between innate and adaptive immunity. Although pDCs do not represent the main reservoir of the Human Immunodeficiency Virus (HIV), they are a crucial subset in HIV infection as they influence viral transmission, target cell infection and antigen presentation. pDCs act as inflammatory and immunosuppressive cells, thus contributing to HIV disease progression. This review provides a state of art analysis of the interactions between HIV and pDCs and their potential roles in HIV transmission, chronic immune activation and immunosuppression. A thorough understanding of the roles of pDCs in HIV infection will help to improve therapeutic strategies to fight HIV infection, and will further increase our knowledge on this important immune cell subset. PMID- 29588164 TI - Nitrated fatty acids in cardiovascular diseases. AB - Cardiovascular disease (CVD) is the leading cause of death and accounts for one third of disease-related mortality worldwide. Dysregulated redox mechanisms, in particular the formation of reactive oxygen species (ROS) play a pivotal pathogenetic role in CVD. Nitro-fatty acids (NO2-FAs) are electrophilic molecules which have a NO2-group bound to one of their olefinic carbons. They are endogenously formed by the reaction of reactive nitrogen species with unsaturated fatty acids. Basal levels of NO2-FAs are in the low nanomolar range and higher concentrations can be encountered under acidic (stomach) and inflammatory (e.g. ischemia/reperfusion) conditions. Dietary intake of polyunsaturated fatty acids in combination with nitrites raises circulating NO2-FAs to a clinically relevant level in mice. NO2-FAs undergo reversible covalent binding to cysteine residues and by virtue of these posttranslational protein modifications act as potent anti inflammatory signaling mediators via modulation of various critical pathways like nuclear factor E2-related factor 2 (Nrf2)- and peroxisome proliferator-activated receptor gamma (PPARgamma) activation, nuclear factor-kappa B (NF-kappaB) inhibition and hem oxygenase-1 (HO-1)- and heat shock protein (HSP) induction. In this review article, we summarize recent findings about the effects and underlying molecular mechanisms of NO2-FAs from a variety of pre-clinical cardiovascular disease models. The described findings suggest the potential of NO2-FAs to emerge as therapeutic agents with a broad range of potential clinical applications for CVD.

PMID- 29588166 TI - The iron pro-chelator BHAPI attenuates glutamate-induced oxidative stress via Wnt beta/catenin pathway in HT22 cells. AB - Disturbances in intracellular iron homeostasis are associated with brain damage under various neuropathological conditions. However, exposure of neuronal cells to classical iron chelators could interfere with physiological iron functions in the brain. Thus, iron pro-chelators represent a more advanced approach to exert strong free-iron binding capacity only under oxidative stress conditions. In the present study, we investigated the protective effects of an iron pro-chelator BHAPI [(E)-N'-(1-(2-((4- (4,4,5,5-tetramethyl-1,2,3-dioxoborolan-2 yl)benzyl)oxy)phenyl)ethylidene) isonicotino hydrazide] against glutamate-induced toxicity in neuronal HT22 cells. The results showed that BHAPI significantly increased cell viability, decreased lactate dehydrogenase (LDH) release, inhibited apoptotic cell death and reduced the activation of caspase-3 after glutamate treatment. This protection was accompanied by the preservation of mitochondrial function, as evidenced by reduced mitochondrial oxidative stress, attenuated lipid peroxidation and enhanced ATP generation. In addition, BHAPI promoted Wnt/beta-catenin signaling, which was related to destabilization of beta catenin destruction complex. The Wnt/beta-catenin signaling inhibitor JW74, but not IWP2, partially prevented the protective effects of BHAPI. In conclusion, our data suggested that BHAPI acted as a neuroprotective agent against glutamate induced toxicity, and this protection might be mediated by preservation of mitochondrial function and regulation of Wnt/beta-catenin pathway.

PMID- 29588168 TI - Epidemicity thresholds for water-borne and water-related diseases. AB - Determining the conditions that favor pathogen establishment in a host community is key to disease control and eradication. However, focusing on long-term dynamics alone may lead to an underestimation of the threats imposed by outbreaks triggered by short-term transient phenomena. Achieving an effective epidemiological response thus requires to look at different timescales, each of which may be endowed with specific management objectives. In this work we aim to determine epidemicity thresholds for some prototypical examples of water-borne and water-related diseases, a diverse family of infections transmitted either directly through water infested with pathogens or by vectors whose lifecycles are closely associated with water. From a technical perspective, while conditions for endemicity are determined via stability analysis, epidemicity thresholds are defined through generalized reactivity analysis, a recently proposed method that allows the study of the short-term instability properties of ecological systems. Understanding the drivers of water-borne and water-related disease dynamics over timescales that may be relevant to epidemic and/or endemic transmission is a challenge of the utmost importance, as large portions of the developing world are still struggling with the burden imposed by these infections. PMID- 29588169 TI - The Adaptor Protein ENY2 Is a Component of the Deubiquitination Module of the Arabidopsis SAGA Transcriptional Co-activator Complex but not of the TREX-2 Complex. AB - The conserved nuclear protein ENY2 (Sus1 in yeast) is involved in coupling transcription and mRNA export in yeast and metazoa, as it is a component both of the transcriptional co-activator complex SAGA and of the mRNA export complex TREX 2. Arabidopsis thaliana ENY2 is widely expressed in the plant and it localizes to the nucleoplasm, but unlike its yeast/metazoan orthologs, it is not enriched in the nuclear envelope. Affinity purification of ENY2 in combination with mass spectrometry revealed that it co-purified with SAGA components, but not with the nuclear pore-associated TREX-2. In addition, further targeted proteomics analyses by reciprocal tagging established the composition of the Arabidopsis SAGA complex consisting of the four modules HATm, SPTm, TAFm and DUBm, and that several SAGA subunits occur in alternative variants. While the HATm, SPTm and TAFm robustly co purified with each other, the deubiquitination module (DUBm) appears to associate with the other SAGA modules more weakly/dynamically. Consistent with a homology model of the Arabidopsis DUBm, the SGF11 protein interacts directly with ENY2 and UBP22. Plants depleted in the DUBm components, SGF11 or ENY2, are phenotypically only mildly affected, but they contain increased levels of ubiquitinated histone H2B, indicating that the SAGA-DUBm has histone deubiquitination activity in plants. In addition to transcription-related proteins (i.e., transcript elongation factors, Mediator), many splicing factors were found to associate with SAGA, linking the SAGA complex and ongoing transcription with mRNA processing. PMID- 29588170 TI - Comparison of liraglutide plus basal insulin and basal-bolus insulin therapy (BBIT) for glycemic control, body weight stability, and treatment satisfaction in patients treated using BBIT for type 2 diabetes without severe insulin deficiency: A randomized prospective pilot study. AB - AIMS: We examined whether 0.9 mg/day liraglutide plus basal insulin (Lira-basal) is superior to basal-bolus insulin therapy (BBIT) for type 2 diabetes (T2DM) without severe insulin deficiency as determined by glucagon stimulation. METHODS: Fifty patients receiving BBIT were enrolled in this 24-week, prospective, randomized, open-labeled study. After excluding subjects with fasting C-peptide immunoreactivity (CPR) < 1.0 ng/mL and CPR increase < 1.0 ng/mL at 6 min post glucagon injection, 25 were randomly allocated to receive Lira-basal (n = 12) or continued BBIT (n = 13). Primary endpoint was change in HbA1c. Secondary endpoints were changes in body weight (BW), 7-point self-monitored blood glucose (SMBG), and Diabetes Treatment Satisfaction Questionnaire status (DTSQs) scores. RESULT: The Lira-basal group demonstrated reduced HbA1c, whereas the BBIT group showed no change. BW was reduced in the Lira-basal group but increased in the BBIT group. The Lira-basal group also exhibited significantly reduced pre breakfast and pre-lunch SMBG. DTSQs scores improved in the Lira-basal group but not the BBIT group. Plasma lipids, liver function, and kidney function were not significantly changed in either group. CONCLUSIONS: Lira-basal therapy is superior to BBIT for T2DM without severe insulin deficiency. This study was registered with UMIN Clinical Trials Registry (UMIN000028313). PMID- 29588171 TI - Mechanism of adrenomedullin 2/intermedin mediated vasorelaxation in rat main pulmonary artery. AB - Adrenomedullin 2/intermedin (AM2/IMD) is a member of calcitonin related gene peptide family and an important nitric oxide mediated vasorelaxant in various vascular beds. However, the mechanism of post receptor-interaction is not clear and may differ depending on tissue type and species. In this study, we aimed to investigate the exact mechanism and the role of BKCa and calcium channels on the vasorelaxant effect of AM2/IMD in rat PA. Changes in the AM2/IMD-mediated vasorelaxation were evaluated in the presence of various inhibitors. CGRP(8-37) (10-6 M), L-NAME (10-4 M), ODQ (10-5 M), SQ22536 (10-4 M), H89 (10-6 M), TEA (10 2 M), iberiotoxin (3 * 10-7 M), and verapamil (10-5 M), all partly or completely inhibited the vasorelaxation. The relaxation was also abolished by removal of the endothelium, or in KCl precontracted PAs. AM2/IMD did not elicit vasorelaxation in the Ca2+-free conditions. However, the vasorelaxation was not inhibited with AM(22-52) (10-6 M), 4-AP (3 * 10-3 M), glibenclamide (10-5 M), apamin (3 * 10-7 M), TRAM-34 (10-5 M), and La+3 (10-4 M). AM2/IMD -induced changes in intracellular calcium levels and isometric force were monitored simultaneously in fura-2-loaded, endothelium-intact PAs. The AM2/IMD-induced increase in intracellular Ca2+ concentration was inhibited in the presence of iberiotoxin and verapamil, whereas no change was observed with La3+ incubation. Our data suggest that the cAMP/PKA pathway is one of the important pathways AM2/IMD-induced vasorelaxation. AM2/IMD acts through activation of endothelial BKCa and subsequently causes hyperpolarization of the endothelial cell membrane. The hyperpolarization induces Ca2+ influx, which leads to NO production and subsequent vasorelaxation. PMID- 29588172 TI - Short-term perception of and conditioned taste aversion to umami taste, and oral expression patterns of umami taste receptors in chickens. AB - Umami taste is one of the five basic tastes (sweet, umami, bitter, sour, and salty), and is elicited by l-glutamate salts and 5'-ribonucleotides. In chickens, the elucidation of the umami taste sense is an important step in the production of new feedstuff for the animal industry. Although previous studies found that chickens show a preference for umami compounds in long-term behavioral tests, there are limitations to our understanding of the role of the umami taste sense in chicken oral tissues because the long-term tests partly reflected post ingestive effects. Here, we performed a short-term test and observed agonists of chicken umami taste receptor, l-alanine and l-serine, affected the solution intakes of chickens. Using this method, we found that chickens could respond to umami solutions containing monosodium l-glutamate (MSG) + inosine 5' monophosphate (IMP) within 5 min. We also demonstrated that chickens were successfully conditioned to avoid umami solution by the conditioned taste aversion test. It is noted that conditioning to umami solution was generalized to salty and sweet solutions. Thus, chickens may perceive umami taste as a salty- and sweet-like taste. In addition, we found that umami taste receptor candidates were differentially expressed in different regions of the chicken oral tissues. Taken together, the present results strongly suggest that chickens have a sense of umami taste and have umami taste receptors in their oral tissue. PMID- 29588173 TI - PIL5 represses floral transition in Arabidopsis under long day conditions. AB - PHYTOCHROME INTERACING FACTOR 3 LIKE 5 (PIL5), also named PHYTOCHROME INTERACTING FACTOR 1 (PIF1) is an important b-HLH transcription factor in Arabidopsis thaliana. Here we show that mutant of pil5-1 displays early flowering phenotype. We demonstrate that the expressions of the major flowering promoter genes [FLOWERING LOCUS T (FT), SUPPRESOR OF OVEREXPRESSION OF CO 1 (SOC1), and LEAFY (LFY)] are upregulated in the mutant of pil5-1. There is a significant increase of the mRNA of PIL5 in the mutants of co2-1, ft-10, soc1-2, and lfy-4. These changes provide the molecular evidence that PIL5 interacts with the flowering regulators to control flowering time. Moreover, it is shown in our results that PIL5 mutation mediates the increased contents of gibberellic acid (GA). Which is further supported by the qRT-PCR analysis, an increased transcriptome level of the GA biosynthesis genes (GA3ox1, GA3ox2, GA20ox1, GA20ox2, and GA20ox3) has been observed in the pil5-1 mutants as compared to the wild type. Collectively, PIL5 is involved in floral transition interacting with flowering integrators and GA. PMID- 29588175 TI - Identification and analysis of microRNAs-mRNAs pairs associated with nutritional status in seasonal sheep. AB - Given the important role of nutritional status for reproductive performance, we aimed to explore the potential microRNA (miRNA)-mRNA pairs and their regulatory roles associated with nutritional status in seasonal reproducing sheep. Individual ewes were treated with and without 0.3 kg/day concentrates, and the body condition score, estrus rate, and related miRNAs and target genes were compared. A total of 261 differentially expressed miRNAs were identified, including 148 hypothalamus-expressed miRNAs and 113 ovary-expressed miRNAs, and 349 target genes were predicted to be associated with nutritional status and seasonal reproduction in sheep. Ultimately, the miR-200b-GNAQ pair was screened and validated as differentially expressed, and a dual luciferase reporter assay showed that miR-200b could bind to the 3'-untranslated region of GNAQ to mediate the hypothalamic-pituitary-ovarian axis. Thus, miR-200b and its target gene GNAQ likely represent an important negative feedback loop, providing a link between nutritional status and seasonal reproduction in sheep toward enhancing reproductive performance and productivity. PMID- 29588176 TI - Modality-dependent effect of motion information in sensory-motor synchronised tapping. AB - Synchronised action is important for everyday life. Generally, the auditory domain is more sensitive for coding temporal information, and previous studies have shown that auditory-motor synchronisation is much more precise than visuo motor synchronisation. Interestingly, adding motion information improves synchronisation with visual stimuli and the advantage of the auditory modality seems to diminish. However, whether adding motion information also improves auditory-motor synchronisation remains unknown. This study compared tapping accuracy with a stationary or moving stimulus in both auditory and visual modalities. Participants were instructed to tap in synchrony with the onset of a sound or flash in the stationary condition, while these stimuli were perceived as moving from side to side in the motion condition. The results demonstrated that synchronised tapping with a moving visual stimulus was significantly more accurate than tapping with a stationary visual stimulus, as previous studies have shown. However, tapping with a moving auditory stimulus was significantly poorer than tapping with a stationary auditory stimulus. Although motion information impaired audio-motor synchronisation, an advantage of auditory modality compared to visual modality still existed. These findings are likely the result of higher temporal resolution in the auditory domain, which is likely due to the physiological and structural differences in the auditory and visual pathways in the brain. PMID- 29588174 TI - Serglycin is involved in inflammatory response in articular mouse chondrocytes. AB - Serglycin is expressed by a variety of cell types and mediates different functions in both normal and pathological conditions by interacting with different biological molecules, such as the CD44 receptor. Many studies suggest that serglycin has a crucial role in inflammatory response, but there are limited data on the functions of this proteoglycan in chondrocytes. In this study we investigated the effect of serglycin knockdown induced by a specific serglycin small interfering RNA (SRGN siRNA) in normal mouse chondrocytes stimulated with lipopolysaccharide (LPS). LPS administration in normal chondrocytes increased the expression of serglycin mRNA and related protein and the production of the pro inflammatory mediators TNF-alpha, IL-1beta, IL-6, iNOS and MMP-9, through NF-kB activation. In addition, a marked increased expression of CD44 after LPS stimulation was observed. Notably, the CD44 expression and the inflammatory response were significantly reduced by SRGN siRNA treatment in LPS treated chondrocytes. Similar results were obtained in normal mouse chondrocytes exposed to LPS, using a specific blocking antibody against CD44. These results indicate that serglycin produced in LPS-induced inflammation in normal mouse chondrocytes is able to modulate inflammation by interacting with CD44 receptor, suggesting a possible key role in the cartilage inflammation. PMID- 29588177 TI - A 43-year-old woman with unexplained elevation of hCG. AB - OBJECTIVE: This case report investigates an unusual hCG result in a woman who is not pregnant. PATIENT AND METHODS: A 43-year-old woman was admitted for recurrence of thrombotic thrombocytopenic purpura (TTP) and therapeutic plasma exchange (TPE) was initiated. Prior to transitioning the patient from TPE to immunosuppressive therapy, a serum qualitative hCG test was performed and was positive. Several etiologies for elevated hCG were considered and investigated, including heterophile antibody interference, endogenous hCG from pituitary or malignancy, and exogenous hCG. RESULTS: Retrospective measurement of hCG levels in remnant samples, including a sample obtained prior to TPE initiation, demonstrated that the hCG elevation occurred with plasma administration for TPE. Further investigation with the American Red Cross confirmed that a plasma donor was unknowingly pregnant and in the latter half of the first trimester at the time of donation, when hCG levels peak. CONCLUSION: In plasma recipients with unexplained hCG elevation, passive transfer of hCG from plasma should be considered in the differential diagnosis. Retrospective measurement of hCG in remnant samples obtained prior to plasma exchange can assist in confirming the source. PMID- 29588178 TI - Morphological analysis and three-dimensional reconstruction of the SMAS surrounding the nasolabial fold. AB - BACKGROUND: The superficial musculoaponeurotic system (SMAS), a structure that has been discussed with some controversy, has a complex morphological architecture. MATERIAL AND METHODS: Histological analysis was performed on tissue blocks of the nasolabial fold (NLF) collected postmortem from formalin-fixed bodies of one male and one female donor. Serial histological sections were made, stained and digitized. Three-dimensional reconstructions of the histological structures were performed. Specimen- and location-specific differences were determined. SEM analysis of the NLF tissue block was performed. RESULTS: The NLF SMAS is a fibro-muscular, three-dimensional meshwork bolstered with fat cells. Two SMAS structure types were identified adjacent to the NLF. The cheek SMAS structure showed a regular, vertical and parallel alignment of the fibrous septa, building a three-dimensional meshwork of intercommunicating compartments. It changed its morphology, condensing while transiting the NLF and passing over to form an irregular structure in the upper lip region. SEM analysis demonstrated the connection between the fibrous meshwork and the fat cells. SMAS blood circulation expanded subcutaneously without perforating the fibro-muscular septa. CONCLUSIONS: The NLF has a recognizable condensed cheek SMAS structure and represents the transition zone between the two SMAS types. Specimen-specific morphological differences necessitate individual planning and area-specific surgical procedures. PMID- 29588179 TI - Assessment of a subset of Slowly Mutating Y-STRs for forensic and evolutionary studies. AB - Y-specific short tandem repeat (Y-STR) loci display different mutation rates and consequently are suitable for forensic, genealogical, and evolutionary studies that require different levels of timelines and resolution. Recent efforts have focused on implementing Rapidly Mutating (RM) Y-STRs to assess male specific profiles. However, due to their high mutation rate their use in kinship testing or in phylogenetic studies may be less reliable. In the present study, a novel Slowly Mutating Y-STR (SM) panel, including DYS388, DYS426, DYS461 (Y-GATA-A7.2), DYS485, DYS525, and DYS561, has been developed and evaluated in a sample set of 628 unrelated males from different worldwide populations. This panel is reproducible, sensitive, and robust for forensic applications and may be useful in conjunction with the common multiplexes, particularly in exclusion of kinship cases where minimal discrimination is reported employing the rapidly mutating Y STR systems. Furthermore, SM Y-STR data may be of value in evolutionary studies to optimize the resolution of phylogenetic relationships generated with current Y STR panel sets. In this study, we provide an extensive Y-STR allele and haplotype reference dataset for future applications. PMID- 29588181 TI - Spectroelectrochemical detection of microRNA-155 based on functional RNA immobilization onto ITO/GNP nanopattern. AB - We fabricated a microRNA biosensor using the combination of surface enhanced Raman spectroscopy (SERS) and electrochemical (EC) techniques. For the first time, the weaknesses of each techniques for microRNA detection was compensated by the other ones to give rise to the specific and wide-range detection of miR-155. A single stranded 3' methylene blue (MB) and 5' thiol-modified RNA (MB-ssRNA-SH) was designed to detect the target miR-155 and immobilized onto the gold nanoparticle-modified ITO (ITO/GNP). Upon the invasion of target strand, the double-stranded RNA transformed rapidly to an upright structure resulting in a notable decrease in SERS and redox signals of the MB. For the first time, by combination of SERS and EC techniques in a single platform we extended the dynamic range of both techniques from 10 pM to 450 nM (SERS: 10 pM-5 nM and EC: 5 nM-450 nM). As well, the SERS technique improved the detection limit of the EC method from 100 pM to 100 fM, while the EC method covered single-mismatch detection which was the SERS deficiency. The fabricated single-step biosensor possessing a good capability of miRNA detection in human serum, could be employed throughout the broad ranges of biomedical and bioelectronics applications. PMID- 29588180 TI - Selenium versus sulfur: Reversibility of chemical reactions and resistance to permanent oxidation in proteins and nucleic acids. AB - This review highlights the contributions of Jean Chaudiere to the field of selenium biochemistry. Chaudiere was the first to recognize that one of the main reasons that selenium in the form of selenocysteine is used in proteins is due to the fact that it strongly resists permanent oxidation. The foundations for this important concept was laid down by Al Tappel in the 1960's and even before by others. The concept of oxygen tolerance first recognized in the study of glutathione peroxidase was further advanced and refined by those studying [NiFeSe]-hydrogenases, selenosubtilisin, and thioredoxin reductase. After 200 years of selenium research, work by Marcus Conrad and coworkers studying glutathione peroxidase-4 has provided definitive evidence for Chaudiere's original hypothesis (Ingold et al., 2018) [36]. While the reaction of selenium with oxygen is readily reversible, there are many other examples of this phenomenon of reversibility. Many reactions of selenium can be described as "easy in - easy out". This is due to the strong nucleophilic character of selenium to attack electrophiles, but then this reaction can be reversed due to the strong electrophilic character of selenium and the weakness of the selenium-carbon bond. Several examples of this are described. PMID- 29588182 TI - Continuous citric acid production in repeated-fed batch fermentation by Aspergillus niger immobilized on a new porous foam. AB - The efficiency of current methods for industrial production of citric acid is limited. To achieve continuous citric acid production with enhanced yield and reduced cost, immobilized fermentation was employed in an Aspergillus niger 831 repeated fed-batch fermentation system. We developed a new type of material (PAF201), which was used as a carrier for the novel adsorption immobilization system. Hydrophobicity, pore size and concentration of carriers were researched in A. niger immobilization. The efficiency of the A. niger immobilization process was analyzed by scanning electron microscopy. Then eight-cycle repeated fed-batch cultures for citric acid production were carried out over 600 h, which showed stable production with maximum citric acid concentrations and productivity levels of 162.7 g/L and 2.26 g L-1 h-1, respectively. Compared with some other literatures about citric acid yield, PAF201 immobilization system is 11.3% higher than previous results. These results indicated that use of the new adsorption immobilization system could greatly improve citric acid productivity in repeated fed-batch fermentation. Moreover, these results could provide a guideline for A.niger or other filamentous fungi immobilization in industry. PMID- 29588183 TI - HLA-G is expressed in intestinal samples of ulcerative colitis and Crohn's disease patients and HLA-G5 expression is differentially correlated with TNF and IL-10 cytokine expression. AB - HLA-G is an immunomodulatory molecule that can be produced by epithelial cells. Considering that TNF and IL-10 participate in bowel inflammatory disorders and that both cytokines modulate HLA-G, we evaluated HLA-G, TNF and IL-10 mRNA expression by qPCR and HLA-G protein levels by immunohistochemistry in two intestinal samples exhibiting different degree of inflammation within a patient suffering from Crohn's disease (CD) or ulcerative colitis (UC). Tissue HLA-G5 (P < 0.0001), TNF (P = 0.0004) and IL-10 (P = 0.0169) mRNA expression levels were higher in intestinal areas exhibiting intense inflammation compared to areas of low inflammation, and HLA-G protein levels were not associated with degree of mucosal inflammation. In CD, the expression of TNF was correlated with IL-10 in low inflamed areas, exhibiting a TNF:IL-10 ratio = 3, but in inflamed areas the ratio increased to 9-folds. In UC, the expression of TNF was correlated to IL-10, irrespective of the inflammation grade, with little variation of the TNF:IL-10 ratio in the various inflamed areas. TNF and IL-10 expression was correlated with HLA-G5 expression in mild inflamed areas. Both CD and UC samples exhibited gene and protein expression of HLA-G; and the HLA-G5 expression is differentially correlated with TNF and IL-10 levels depending on the type of the underlying inflammatory bowel disorder. PMID- 29588184 TI - The matrices and constraints of GT/AG splice sites of more than 1000 species/lineages. AB - To provide a resource for the splice sites (SS) of different species, we calculated the matrices of nucleotide compositions of about 38 million splice sites from >1000 species/lineages. The matrices are enriched of aGGTAAGT (5'SS) or (Y)6N(C/t)AG(g/a)t (3'SS) overall; however, they are quite diverse among hundreds of species. The diverse matrices remain prominent even under sequence selection pressures, suggesting the existence of diverse constraints as well as U snRNAs and other spliceosomal factors and/or their interactions with the splice sites. Using an algorithm to measure and compare the splice site constraints across all species, we demonstrate their distinct differences quantitatively. As an example of the resource's application to answering specific questions, we confirm that high constraints of particular positions are significantly associated with transcriptome-wide, increased occurrences of alternative splicing when uncommon nucleotides are present. More interestingly, the abundance of alternative splicing in 16 species correlates with the average constraint index of splice sites in a bell curve. This resource will allow users to assess specific sequences/splice sites against the consensus of every Ensembl-annotated species, and to explore the evolutionary changes or relationship to alternative splicing and transcriptome diversity. Web-search or update features are also included. PMID- 29588185 TI - Septic shock due to meropenem- and colistin-resistant Cupriavidus pauculus. PMID- 29588186 TI - The handwash station: friend or fiend? AB - Handwashing is a key barrier to cross-infection performed at a handwash station (HWS, an interface between water and drainage systems). Widespread and often uncritical placement/design and use of HWSs is not without attendant risks. Recognition of the associated hazards went unheeded for over 45 years despite warnings in the literature, until the neonatal outbreak of pseudomonas in Belfast in 2012 forced change. Minimizing risk requires a holistic approach beyond the mere testing of water from the outlet of a HWS for the presence of Pseudomonas aeruginosa or other pathogens. Literature reports of outbreaks linked to HWSs outside of neonatal units are over-represented by multi-resistant organisms, and increasingly by carbapenemase-producing organisms. Evidence suggests that a large proportion of waterborne transmissions go undetected. Much could be done to improve current design, use and placement of HWSs, and this is assessed critically in this article. PMID- 29588187 TI - Effect of chlorhexidine baths on central-line-associated bloodstream infections in a neonatal intensive care unit in a developing country. AB - Healthcare-associated infections, particularly central-line-associated bloodstream infections (CLABSIs), are worrisome in neonates. This study describes the impact of chlorhexidine baths on CLABSI rates in a neonatal intensive care unit in a developing country, through a quasi-experimental study undertaken over 62 months (January 2012 to February 2017) divided into two periods: before and after the implementation of a protocol for chlorhexidine baths in July 2014. The rate of CLABSIs per 1000 central-line-days decreased from 8.64 to 4.28 after implementation of the protocol. The use of chlorhexidine baths appears to reduce the number of CLABSIs in neonates. PMID- 29588188 TI - 3D computer simulation analysis of the flap volume change in total tongue reconstruction flaps. AB - BACKGROUND: A decreased flap volume can be an obstacle to proper phonation and swallowing. In this study we verified the proportion of volume decrease using 3D reconstructed images and identified the contributors to flap volume loss. METHODS: We retrospectively analyzed all patients who underwent radical excision of tongue cancer and reconstructive surgery in our institution from January 2003 to October 2016. Segmentation of the DICOM images, 3D rendering of the neotongue flap, and analysis of the reconstructed images were performed using SPlanner V1(r) software. RESULTS: The first postoperative imaging work-up was performed within an average of 22 days (T1). The last follow-up images were taken at an average of 6.25 months (T2). The mean flap volume at T2 was reduced to 82.99 per cent compared with T1, and flap height was reduced to 91.85 per cent, giving mean volume and height decreases of 17.01 per cent and 8.15 per cent, respectively. Neither the volume/height difference between T1 and T2 nor the flap volume/height discrepancy compared with the preoperative tongue affected speech or feeding function. The difference between the flap and preoperative tongue volumes was significantly related to the presence of complications (p = 0.0153). Initial flap volume was significantly related to the flap volume reduction (p = 0.0159). CONCLUSIONS: The mean flap volume reduction is the only factor significantly related to initial flap volume. Our realistic 3D reconstructed image and novel software enables us to more precisely predict the flap volume of the postoperative state and preoperatively evaluate the required flap size for covering defects.

AB - PURPOSE: Recent studies have emphasized the role of podoplanin in oral lesions at risk of malignant transformation. We investigated a group of oral leukoplakias (OLs) to determine a possible relation between altered podoplanin expression and dysplasia, and to compare the results with those obtained by other, widely used biomarkers. MATERIALS AND METHODS: The population consisted of 40 consecutive patients with a clinical and histological diagnosis of OL. Thirty-two OLs did not show dysplasia, whereas eight lesions presented with dysplasia. Immunohistochemical expression of podoplanin, p53 and Ki67 was analyzed in all samples. RESULTS: All three biomarkers were positive in seven of eight dysplastic OLs. Among the 32 OLs without dysplasia, Ki67 and p53 showed positive values in 21 and 10 samples respectively, whereas podoplanin was positive in only one case. Multiple logistic regression showed that podoplanin was the most powerful variable (Chi square 9.77; p < .01) statistically related to the presence of dysplasia. In addition, podoplanin showed a higher specificity value (96.87%) than Ki67 (34.37%) and p53 (68.75%). CONCLUSION: Podoplanin seems to be a reliable means of discriminating lesions with epithelial dysplasia and could be introduced in routine practice as a marker to discriminate OLs at risk of developing cancer. PMID- 29588191 TI - Arachidonic acid metabolites of CYP4A and CYP4F are altered in women with preeclampsia. AB - Few studies exist on cytochrome P450 (CYP450) metabolites of arachidonic acid (AA) pertaining to the pathophysiological events in pregnancy. We hypothesized that metabolism of AA via the CYP450 pathways is altered within the placenta in women with preeclampsia (PE) and contributes to the pathophysiology of the disease. Thus, placental vascular CYP450 enzyme expression and activity were measured in normal pregnant (NP) and preeclamptic (PE) patients. CYP450 isoform expression (CYP4A11, CYP4A22, CYP4F2, and CYP4F3) was found to be elevated within the placenta of women with PE compared to normal pregnant (NP) women and chronic hypertensive (CHTN) pregnant women. In addition, placental production of 20-HETE was significantly increased in PE women compared to both NP and CHTN women. Moreover, there was an imbalance in circulating 20-HETE:EETs in PE women. To examine whether alterations in CYP450 AA metabolism contribute to the altered placentation in PE, trophoblast function, proliferation and migration were assessed in the presence of exogenous 20-HETE and a 20-HETE specific synthesis inhibitor, HET0016. Trophoblast proliferation was significantly increased in the presence of 20-HETE (1 MUM) and reduced with 20-HETE blockade by HET0016 (1 mM, 5 mM, and 10 mM). On the contrary, administration of exogenous 20-HETE (1 MUM) significantly reduced trophoblast migration. In conclusion, metabolism of AA via CYP450 is altered in PE, and increased placental production of 20-HETE may contribute to the pathophysiology of the disease. PMID- 29588192 TI - Cardiovascular diseases, NLRP3 inflammasome, and western dietary patterns. AB - Cardiovascular diseases (CVD) are the leading cause of death worldwide, with high prevalence in industrialized countries. Cardiovascular risk factors are mainly influenced by diet, which like other lifestyle factors can be modified to either reduce or increase cardiovascular risk. Other metabolic diseases such as metabolic syndrome, type II diabetes mellitus, and obesity are associated to CVD and highly influenced by the diet. Inflammation has demonstrated to be a key factor in the biological progress of these diseases. Interestingly, IL-1beta which is associated to several steps in the development of atherosclerosis, heart disease, and the association of obesity and type II diabetes with CVD, is activated by the inflammasome complex, a multiprotein complex composed of an intracellular sensor, typically a Nod-like receptor (NLR), the precursor procaspase-1, and the adaptor ASC (apoptosis-associated speck-like protein containing a CARD. In the last years, inflammasome complex has been studied in depth and has been associated with the effect of unhealthy diets both from a clinical and experimental view point. We have reviewed the evidences supporting the role of the inflammasome complex in the development of cardiovascular pathology by unhealthy diets and the therapeutic perspectives. PMID- 29588193 TI - Cross-talk between endogenous H2S and NO accounts for vascular protective activity of the metal-nonoate Zn(PipNONO)Cl. AB - Nitric oxide (NO) and hydrogen sulfide (H2S) are now recognized as gaseous transmitters with many cardiovascular protective properties. The present study concerns the possibility that NO donors can also function through endogenous activation of NO and H2S pathways. Based on the previous characterization of a novel metal-nonoate, Ni(PipNONO)Cl, our aim was: 1) to study the effects of a zinc based compound, Zn(PipNONO)Cl, on vascular endothelial and smooth muscle cells, and 2) to assess the role and interplay between endogenous NO and H2S promoted by the nonoate. Zn(PipNONO)Cl completely reproduced the vasodilation elicited by Ni(PipNONO)Cl. In the presence of endothelium, preincubation with Zn(PipNONO)Cl sensitized the intima to acetylcholine-induced vasodilation. When tested on cultured endothelial cells, Zn(PipNONO)Cl prompted PI-3K/Akt- and MAPK/ERK1/2-mediated survival. Nitrite levels indicated fast NO release (due to the molecule) and delayed (1-6 h) NO production linked to PI-3K/Akt-dependent eNOS activation. In the same time frame (1-6 h), significant CSE-dependent H2S levels were detected in response to Zn(PipNONO)Cl. The mechanisms responsible for H2S increase seemed to depend on the NONO moiety/sGC/cGMP pathway and zinc associated ROS production. Our results indicate that endogenous H2S and NO were produced after fast NO release from Zn(PipNONO)Cl, contributing to the vascular endothelium protective effect. The effect was partially reproduced on smooth muscle cells, where Zn(PipNONO)Cl inhibited cell proliferation and migration. In conclusion, vasorelaxant effects, with complementary activities on endothelium and smooth muscle cells, are elicited by the novel metal-nonoate Zn(PipNONO)Cl. PMID- 29588194 TI - Using chemical bond-based method to predict site of metabolism for five biotransformations mediated by CYP 3A4, 2D6, and 2C9. AB - Although it has been proposed for decades to predict site of metabolism (SOM) by in silico methods, identifying SOM correctly remains an unsolved fundamental problem and is an active area of research. In our prior works, we proposed a chemical bond-based approach to construction of SOM prediction models by integrating chemical bond descriptors and drug-metabolizing enzymes data. Although it has been evaluated with both 10-fold cross-validation and independent validation, we believe comparisons between this method and prior methods using publicly accessible external datasets are indispensable and more desirable. In the current study, based on chemical bond-based method, metabolism data released by Sheridan et al. and Zaretzki et al. was utilized to establish metabolite prediction models for CYP450 3A4, 2D6, and 2C9. Five major reaction types were involved, including Aliphatic C-hydroxylation, Aromatic C-hydroxylation, N dealkylation, O-dealkylation, and S-Oxidation. Consequently, all our five models showed impressive performance on predicting SOMs, with accuracy and area under curve exceeded 0.940 and 0.953, respectively. Compared to prior works, our models were better than SOMP both in "SOM-scale" and "molecule-scale". In conclusion, comparisons between chemical-bond based method and prior works were conducted for the first time, which demonstrated that chemical-bond based method is better than or at least comparable to prior works. PMID- 29588195 TI - Simultaneous profiling of activity patterns in multiple neuronal subclasses. AB - BACKGROUND: Neuronal networks typically comprise heterogeneous populations of neurons. A core objective when seeking to understand such networks, therefore, is to identify what roles these different neuronal classes play. Acquiring single cell electrophysiology data for multiple cell classes can prove to be a large and daunting task. Alternatively, Ca2+ network imaging provides activity profiles of large numbers of neurons simultaneously, but without distinguishing between cell classes. NEW METHOD: We therefore developed a strategy for combining cellular electrophysiology, Ca2+ network imaging, and immunohistochemistry to provide activity profiles for multiple cell classes at once. This involves cross referencing easily identifiable landmarks between imaging of the live and fixed tissue, and then using custom MATLAB functions to realign the two imaging data sets, to correct for distortions of the tissue introduced by the fixation or immunohistochemical processing. RESULTS: We illustrate the methodology for analyses of activity profiles during epileptiform events recorded in mouse brain slices. We further demonstrate the activity profile of a population of parvalbumin-positive interneurons prior, during, and following a seizure-like event. COMPARISON WITH EXISTING METHODS: Current approaches to Ca2+ network imaging analyses are severely limited in their ability to subclassify neurons, and often rely on transgenic approaches to identify cell classes. In contrast, our methodology is a generic, affordable, and flexible technique to characterize neuronal behaviour with respect to classification based on morphological and neurochemical identity. CONCLUSIONS: We present a new approach for analysing Ca2+ network imaging datasets, and use this to explore the parvalbumin-positive interneuron activity during epileptiform events. PMID- 29588196 TI - Ethanol production from sweet sorghum by Saccharomyces cerevisiae DBKKUY-53 immobilized on alginate-loofah matrices. AB - Ethanol production from sweet sorghum juice (SSJ) using the thermotolerant Saccharomyces cerevisiae strain DBKKUY-53 immobilized in an alginate-loofah matrix (ALM) was successfully developed. As found in this study, an ALM with dimensions of 20*20*5mm3 is effective for cell immobilization due to its compact structure and long-term stability. The ALM-immobilized cell system exhibited greater ethanol production efficiency than the freely suspended cell system. By using a central composite design (CCD), the optimum conditions for ethanol production from SSJ by ALM-immobilized cells were determined. The maximum ethanol concentration and volumetric ethanol productivity obtained using ALM-immobilized cells under the optimal conditions were 97.54g/L and 1.36g/Lh, respectively. The use of the ALM-immobilized cells was successful for at least six consecutive batches (360h) without any loss of ethanol production efficiency, suggesting their potential application in industrial ethanol production. PMID- 29588197 TI - Screening of medium constituents for clavulanic acid production by Streptomyces clavuligerus. AB - Clavulanic acid is a beta-lactam compound with potent inhibitory activity against beta-lactamases. Studies have shown that certain amino acids play essential roles in CA biosynthesis. However, quantitative evaluations of the effects of these amino acids are still needed in order to improve CA production. Here, we report a study of the nutritional requirements of Streptomyces clavuligerus for CA production. Firstly, the influence of the primary nitrogen source and the salts composition was investigated. Subsequently, soybean protein isolate was supplemented with arginine (0.0-3.20gL-1), threonine (0.0-1.44gL-1), ornithine (0.0-4.08gL-1), and glutamate (0.0-8.16gL-1), according to a two-level central composite rotatable design. A medium containing ferrous sulfate yielded CA production of 437mgL-1, while a formulation without this salt produced only 41mgL 1 of CA. This substantial difference suggested that Fe2+ is important for CA biosynthesis. The experimental design showed that glutamate and ornithine negatively influenced CA production while arginine and threonine had no influence. The soybean protein isolate provided sufficient C5 precursor for CA biosynthesis, so that supplementation was unnecessary. Screening of medium components, together with experimental design tools, could be a valuable way of enhancing CA titers and reducing the process costs. PMID- 29588198 TI - Identification of enteric viruses circulating in a dog population with low vaccine coverage. AB - Although the use of vaccines has controlled enteric diseases in dogs in many developed countries, vaccine coverage is still under optimal situation in Brazil. There is a large population of nonimmunized dogs and few studies about the identification of the viruses associated with diarrhea. To address this situation, stool samples from 325 dogs were analyzed by polymerase chain reaction for the detection of common enteric viruses such as Canine adenovirus (CAdV), Canine coronavirus (CCoV), Canine distemper virus (CDV), Canine rotavirus (CRV) and Carnivorous protoparvovirus 1 (canine parvovirus 2; CPV-2). At least one of these species was detected in 56.6% (184/325) of the samples. The viruses detected most frequently in either diarrheic or nondiarrheic dog feces were CPV-2 (54.3% of the positive samples), CDV (45.1%) and CCoV (30.4%), followed by CRV (8.2%) and CAdV (4.9%). Only one agent was detected in the majority of the positive samples (63%), but co-infections were present in 37% of the positive samples and mainly included CDV and CPV-2. The data presented herein can improve the clinical knowledge in regions with low vaccine coverage and highlight the need to improve the methods used to control these infectious diseases in domestic dogs.

AB - The consequence of dysanapsis, quantitated by dysanapsis ratio (DR), on expiratory flow limitation (EFL) during exercise in pediatric subjects was examined. EFL occurred in 80 (56%) subjects from an enriched sample of children and adolescents tested during investigation of exertional dyspnea. DR was lower in subjects with vs without EFL during exercise: (0.055 +/- 0.015 vs 0.067 +/- 0.017, p < 0.001), and lower ratio correlated with greater extent of EFL (r = 0.64, p < 0.001). EFL was seen more often in boys: 67% vs 46% (p = 0.01), as girls had higher DR (0.063 +/- 0.016 vs 0.056 +/- 0.018, p = 0.007). Lower FEV1 (95 +/- 17 vs 102 +/- 15%predicted, p < 0.005) and FEF50 (3.47 +/- 1.28 vs 4.08 +/- 1.20 L s-1, p = 0.002) distinguished those with vs without EFL. Inspiratory capacity rose (IC) steadily, as work increased among those with EFL, whereas it fell to back resting levels after an initial rise in subjects without EFL. Low DR predicts EFL in pediatric subjects. Adjusting operating lung volume during exercise can mitigate EFL but this strategy may contribute to exertional dyspnea. PMID- 29588201 TI - Promotive effect of Bofutsushosan (Fangfengtongshengsan) on lipid and cholesterol excretion in feces in mice treated with a high-fat diet. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Bofutsushosan (fangfengtongshengsan in Chinese, BTS) is a formula in traditional Japanese Kampo medicine and Chinese medicine comprising 18 crude drugs that is used for treating obesity and metabolic syndrome. AIM OF THE STUDY: We evaluated the promotive effects of BTS on lipid and cholesterol elimination in mice. MATERIALS AND METHODS: Mice were reared with a high-fat diet containing boiled water extract of BTS for 30 days, and their biochemical parameters as well as the weight and lipid content of feces were measured. We also measured cholesterol uptake into Caco-2 cells cultured with or without BTS extract. RESULTS: The body weight and amounts of visceral fat and subcutaneous fat on day 28; the weights of epididymal, perirenal, and mesenteric fat; and the serum concentrations of triglyceride, glucose, and hemoglobin A1c on day 30 were significantly lower in the BTS extract-treated groups than in the control in a dose-dependent manner. The amounts of lipid and cholesterol in the feces collected from day 6-23 were significantly greater than in the control. When Caco-2 cells were incubated with BTS extract, the uptake of cholesterol into cells was significantly reduced in a concentration-dependent manner. Among the components of BTS, the methanol extracts of Platycodi Radix and Zingiberis Rhizoma contribute but the extracts of Ephedrae Herba and Rhei Rhizoma counteract the suppressive effect of BTS on cholesterol uptake into Caco-2 cells. CONCLUSIONS: BTS has beneficial effects on obesity and metabolic syndrome, and its mechanisms of action include the promotion of lipid elimination and the inhibition of cholesterol absorption in the intestine.

AB - In this study mango kernel starch (MKS) based heat sealable pouches were developed for packing of red chili powder. The films were prepared by casting technique using glycerol, sorbitol and 1:1 mixture of glycerol and sorbitol and were sealed. All films showed better heat sealing capacity but glycerol films plasticized exhibited higher seal strength than their counterparts. The red chili powder was packed in the MKS film pouches while commercially available polyethylene (PE) film was used as control. The pungency and color of red chili powder was monitored during six months storage at 40 degrees C. The capsaicinoid content was extracted from the red chili with acetonitrile and evaluated quantitatively using spectrophotometric method. The extractable color was measured by ASTA method using acetone. The results showed significant differences in color and pungency of chili packed in MKS and PE pouches. The highest reduction in capsaicinoid content (pungency) of chili powder was observed in PE pouch (25.9%) while lowest was observed in MKS pouch containing sorbitol (15.7%). Similarly color loss was also highest in chili packed in PE pouch while lowest in MKS-sorbitol pouch. PMID- 29588203 TI - Synthesis of varisized chitosan-selenium nanocomposites through heating treatment and evaluation of their antioxidant properties. AB - Varisized chitosan-selenium (CS-Se) nanocomposites were synthesized through an innovative method. It is the first time to use CS both as reductant and stabilizer to synthesize selenium nanoparticles (SeNPs). By manipulating the temperature, the well-dispersed CS-Se nanocomposites were synthesized via a simple one pot reaction with the size ranging from 83 to 208nm before being characterized by TEM, DLS, UV-vis, FTIR, XRD and TG analyses. The results showed that SeO32- was reduced to a stable SeNPs colloid at a comparatively high temperature, the amino group and hydroxyl group of CS were conjugated to the surface of SeNPs. Besides, the antioxidant activities of CS-Se nanocomposites were investigated by DPPH, ABTS+, hydroxyl radical, metal ion chelating and reducing power assays, which proved to be concentration-dependent, size-dependent and exhibited good antioxidant activities. The results suggested that CS-Se nanocomposites might be considered as a more appropriate selenium-adding form to achieve antioxidative goals in food. PMID- 29588204 TI - Effect of cross-linking and oxidization on structure and properties of sesbania gum. AB - The effect of cross-linking and oxidization on the structure and properties of sesbania gum (SG) was studied using phosphorus oxychloride as a cross-linking agent, hydrogen peroxide as an oxidant, and ethanol as a solvent. The results showed that the oxidation of SG by hydrogen peroxide was essentially the breaking of long chains without hydroxyl groups being oxidized into carboxyl groups. The breakage of long chains was a key reason of reduction in viscosity. The disruption of SG granules caused by cross-linking was obviously different from the oxidization. The cross-linking had high selectivity, but the oxidization of hydrogen peroxide was random. The crystallinity degree of SG was reduced by cross linking and oxidization. The cross-linking and oxidization obviously changed the thermal properties of SG, and had obvious influence on the freeze-thaw stability, swelling power and retrogadation of SG. The cross-linking degree was well characterized by the surface hydroxyl numbers. The cross-linking was carried out only on SG granule surface according to evidence of alteration in surface hydroxyl numbers. PMID- 29588205 TI - Rational design of novel water-soluble ampholytic cellulose derivatives. AB - The development of new biocompatible, biodegradable functionalized biopolymers that can serve as scaffold for tissue regeneration or work as carriers for different bioactive molecules such as drugs, proteins, and enzymes remains a continuous challenge that need to be extensively explored. For this purpose, three water-soluble cellulose derivatives; namely 4(celluloseamino) butyric acid (CABA) 2(celluloseamino) succinic acid (CASA), and 3(celluloseamino) propane sulfonic acids (CAPSA) were synthesized from microcrystalline cellulose (MCC) via esterification with tosyl chloride that was followed by nucleophilic substitution by the proper aminoalkyl acid derivative. The products were characterized by elemental analyses, FTIR, 13C NMR spectroscopy. The thermal stability, surface morphology, and the elemental composition of the new ampholytic biopolymers were also studied by TGA, EDX-SEM. The new ampholytic cellulose derivatives were evaluated for their in vitro cytotoxicity on normal human retina cell line (RPE1) by MTT assay. PMID- 29588206 TI - Bio-active nanocomposite films based on nanocrystalline cellulose reinforced styrylquinoxalin-grafted-chitosan: Antibacterial and mechanical properties. AB - In this study, active nanocomposite films based on cellulose nanocrystalline (NCC) reinforced styrylquinoxalin-grafted-chitosan are prepared by solvent casting process. The structures of the two styrylquinoxaline derivatives were confirmed by FT-IR, 1H, 13C NMR spectral data and the study of the antibacterial activity against Escherichia coli (EC), Staphylococcus aureus (SA), Bacillus subtilis (BS) and Pseudomonas Aeruginosa (PA) exhibits that they have a good antibacterial activity against (PA). On their side, the styrylquinoxalin-g chitosan films are able to inhibit the growth of (PA) through their contact area without being damaged by the antibacterial test conditions. The addition of 5wt% of NCCs as nano-reinforcements revealed no change at the level of antibacterial activity but led to an important improvement of the mechanical properties (more than 60% and 90% improvement in Young's modulus and tensile strength, respectively) of the modified-chitosan films. Thereby, the present nanocomposite films are prepared by a simple way and featured by good mechanical and antibacterial properties which enhance the possibility to use them as bio-based products for biomedical and food packaging. PMID- 29588207 TI - Study on the effect of graphene and glycerol plasticizer on the properties of chitosan-graphene nanocomposites via in situ green chemical reduction of graphene oxide. AB - Unplasticized and glycerol plasticized chitosan/graphene (CS/GS) nanocomposites were synthesized via in situ chemical reduction of graphene oxide sheets (GO) with l-ascorbic acid (L-AA) as reductant by solution casting. The reduction of GO with L-AA was investigated to establish the optimal amount of reductant required to produce chemically reduced graphene sheets (GS). The combine effect of both nanofiller and glycerol on the structure, thermal, mechanical, and electrical properties of CS/GS nanocomposite films was evaluated. Materials were characterized by FT-IR, NMR, UV-Vis, XPS, XRD, Raman, SEM, TEM, and TGA. The results showed that GS sheets were homogeneously dispersed throughout the CS matrix, and that interactions between CS and the surface of GS took place. When compared with neat CS, nanocomposites showed a decrease in the crystallinity, better thermal stability under oxidative atmosphere, and improved mechanical properties, while maintained the thermal properties of CS under inert conditions. Combined use of glycerol and GS led to substantially enhanced mechanical properties. The electrical conductivity was increased with increasing GS loading in nanocomposite. This study demonstrates how CS/GS nanocomposites performance properties can be tailored by controlling GsS and plasticizer content.

AB - The male-killing symbiont Arsenophonus nasoniae is a gamma-proteobacterium that infects parasitic wasps; the male progeny of infected females exhibit increased embryonic death. In this study, we examined methods to horizontally infect Pteromalus venustus (a parasitoid infesting populations of the alfalfa leafcutting bee Megachile rotundata) with A. nasoniae. We then tested the success of these methods via semi-quantitative PCR and quantitative digital PCR, using a molecular marker specific to A. nasoniae. Controlled parasitoid mating experiments were then undertaken to determine whether infections of A. nasoniae in P. venustus induce the male-killing phenotype as has been reported for other host species; evidence of this male-killing phenotype was observed in the current study. Over the course of the eight parasitoid generations following introduction of A. nasoniae infection in P. venustus, the male component of the parasitoid sex ratio was substantially reduced in the infected population (1.05 ?: 1.00 ?) compared to the control population (2.46 ?: 1.00 ?). Establishment of stable A. nasoniae infections in P. venustus populations could lower the proportion of male progeny, thus negatively impacting the mating success of females, and reducing overall populations of the parasitoid in alfalfa leafcutting bee populations. PMID- 29588208 TI - Application of HTLV-1 tax transgenic mice for therapeutic intervention. AB - Adult T-cell leukemia-lymphoma (ATL) is a refractory T-cell malignancy caused by infection of human T-cell leukemia virus type I (HTLV-I). Although the pathogenesis of ATL remains unclear, HTLV-1 oncoprotein Tax plays an important role in pathogenesis (Matsuoka, 2003; Jeang et al., 2004). Chemotherapy resistance of ATL leads the poor prognosis of this disease. In order to understand the pathogenesis and establish an animal model useful for therapy attempts, we have generated HTLV-1 Tax transgenic mice using the Lck proximal promoter to restrict the Tax expression in T-cells. The HTLV-1 Tax transgenic mice developed diffuse large-cell lymphomas and leukemia with the similar features of a clinical, pathological and immunological characteristic of acute ATL. The fulminant disease also developed rapidly in SCID mice after engraftment of mouse ATL cells derived from the transgenic mice. In this review, we introduce the therapeutic attempts using this animal model and discuss the possible signaling pathway for a therapeutic target. PMID- 29588210 TI - Relating the tableting behavior of piroxicam polytypes to their crystal structures using energy-vector models. AB - Piroxicam crystallises into two polytypes, alpha1 and alpha2, with crystal structures that contain identical molecular layers but differ in the way that these layers are stacked. In spite of having close structural similarity, the polytypes have significantly different powder tabletting behaviour: alpha2 forms only weak tablets at low pressures accompanied by extensive capping and lamination, which make it impossible to form intact tablets above 100 MPa, while alpha1 exhibits superior tabletability over the investigated pressure range (up to 140 MPa). The potential structural origin of the different behaviour is sought using energy-vector models, produced from pairwise intermolecular interaction energies calculated using the PIXEL method. The analysis reveals that the most stabilising intermolecular interactions define columns in both crystal structures. In alpha2, a strongly stabilising interaction between inversion related molecules links these columns into a 2-D network, while no comparable interaction exists in alpha1. The higher dimensionality of the energy-vector model in alpha2 may be one contributor to its inferior tabletability. A consideration of probable slip planes in the structures identifies regions where the benzothiazine groups of the molecules meet. The energy-vector models in this region are geometrically similar for both structures, but the interactions are more stabilising in alpha2 compared to alpha1. This feature may also contribute to the inferior tabletability of alpha2.

AB - Enterohemorrhagic Escherichia coli O157:H7 colonizes the gastrointestinal tract of ruminants, including cattle and bison, which are reservoirs of these zoonotic disease-causing bacteria. Healthy animals colonized by E. coli O157:H7 do not experience clinical symptoms of the disease induced by E. coli O157:H7 infections in humans; however, a variety of host immunological factors may play a role in the amount and frequency of fecal shedding of E. coli O157:H7 by ruminant reservoirs. How gastrointestinal colonization by E. coli O157:H7 impacts these host animal immunological factors is unknown. Here, various isogenic mutant strains of a foodborne isolate of E. coli O157:H7 were used to evaluate bacterial killing capacity of macrophages of cattle and bison, the two ruminant species. Cattle macrophages demonstrated an enhanced ability to phagocytose and kill E. coli O157:H7 compared to bison macrophages, and killing ability was impacted by E. coli O157:H7 virulence gene expression. These findings suggest that the macrophage responses to E. coli O157:H7 might play a role in the variations observed in E. coli O157:H7 fecal shedding by ruminants in nature.

AB - Five series of dihydrotriazine derivatives containing chalcone (13a-i), phenoxy acetophenone (14a-b), benzyl benzene (15a-c), naphthoxyl acetophenone (16a-b) and benzyl naphthalene (17a-h) moieties were designed and synthesized. The antibacterial and antifungal activities of these compounds were evaluated against several strains of Gram-positive and Gram-negative bacteria, as well as a single fungus. Compound 17h was found to be the most potent of all of the compounds tested, with an MIC value of 0.5 MUg/mL against several Gram-positive (Staphylococcus aureus 4220 and QRSA CCARM 3505) and Gram-negative (Escherichia coli 1924) strains of bacteria. However, this compound was inactive against Pseudomonas aeruginosa 2742 and Salmonella typhimurium 2421, indicating that its antibacterial spectrum is similar to those of the positive controls gatifloxacin and moxifloxacin. The cytotoxic activity of the compound 13i, 16b and 17h was assessed in Human normal liver cells. PMID- 29588214 TI - Synthesis of (aminoalkyl)cycleanine analogues: cytotoxicity, cellular uptake, and apoptosis induction in ovarian cancer cells. AB - Our previous studies demonstrated that cycleanine, a macrocyclic bisbenzylisoquinoline (BBIQ) alkaloid, showed potent anti-ovarian cancer activity via apoptosis induction. Here, we synthesized two novel (aminoalkyl)cycleanine analogues (2 and 3) through a simple and efficient two-step reaction starting from cycleanine isolated from Triclisia subcordata Oliv. These analogues showed greater potency than the unmodified cycleanine in three human ovarian cancer cell lines. Both 2 and 3 induced apoptosis in ovarian cancer cells by activations of caspases 3/7, cleavage of PARP, increase in subG1 cell cycle phase and in the percentage of apoptotic cells. Further confocal fluorescence microscopy analysis confirmed the cellular uptake of alkaloids in ovarian cancer cells by using the unique (alkynyl)cycleanine (3) via click chemistry reaction. Our results suggest that cycleanine could be a hit compound for the future development in attacking ovarian cancer.

AB - Inhibition of LRRK2 kinase activity with small molecules has emerged as a potential novel therapeutic treatment for Parkinson's disease. Herein we disclose the discovery of a 4-ethoxy-7H-pyrrolo[2,3-d]pyrimidin-2-amine series as potent LRRK2 inhibitors identified through a kinase-focused set screening. Optimization of the physicochemical properties and kinase selectivity led to the discovery of compound 7, which exhibited potent in vitro inhibition of LRRK2 kinase activity, good physicochemical properties and kinase selectivity across the kinome. Moreover, compound 7 was able to penetrate into the CNS, and in vivo pharmacology studies revealed significant inhibition of Ser935 phosphorylation in the brain of both rats (30 and 100 mg/kg) and mice (45 mg/kg) following oral administration. PMID- 29588216 TI - Bladder Management and Continence Outcomes in Adults with Spina Bifida: Results from the National Spina Bifida Patient Registry, 2009 to 2015. AB - PURPOSE: Most children with spina bifida now survive into adulthood, although most have neuropathic bladder with potential complications of incontinence, infection, renal damage and diminished quality of life. In this study we sought to 1) describe contemporary bladder management and continence outcomes of adults with spina bifida, 2) describe differences from younger individuals and 3) assess for association with socioeconomic factors. MATERIALS AND METHODS: We analyzed data on bladder management and outcomes in adults with spina bifida from the National Spina Bifida Patient Registry. A strict definition of continence was used. Results were compared to young children (age 5 to 11 years) and adolescents (12 to 19). Statistical analysis compared cohorts by gender, ethnicity, spina bifida type, lesion level, insurance status, educational attainment, employment status and continence. RESULTS: A total of 5,250 patients with spina bifida were included, of whom 1,372 (26.1%) were adults. Of the adult patients 45.8% did not take medication, but 76.8% performed clean intermittent catheterization. Continence was decreased in adults with myelomeningocele (45.8%) vs those with nonmyelomeningocele spina bifida (63.1%, p <0.0001). Continence rates were higher in the older cohorts with myelomeningocele (p <0.0001) but not in those with nonmyelomeningocele spina bifida (p = 0.1192). Bladder management and history of urological surgery varied among age groups. On univariate analysis with spina bifida related or socioeconomic variables continence was significantly associated with educational level but on multivariable logistic regression analysis bladder continence was significantly associated with employment status only. CONCLUSIONS: Bladder management techniques differ between adults and children with spina bifida. Bladder continence outcomes were better in adults, with nearly half reporting continence. Continence was significantly associated with employment status in patients age 25 years or older.

AB - Lung cancer is a leading cause of cancer related deaths worldwide and so current research is focused on trying to improve treatment modalities, such as photodynamic therapy (PDT). PDT has 3 fundamental factors, namely a photosensitizer (PS) drug, light and oxygen. When a PS drug is administered to a patient, it can either passively or actively accumulate within a tumour site and once exposed to a specific wavelength of light, it is stimulated to produce reactive oxygen species (ROS), resulting in tumour destruction. However, the efficacy of ROS generation for tumour destruction is highly dependent on the accumulation of the PS in tumour cells. Thus PS selective/targeted uptake and delivery in tumour cells is a crucial factor in PDT cancer drug absorption studies. Generally, within non-targeted drug delivery mechanisms, only small amounts of PS is able to passively accumulates in tumour sites due to the enhanced permeability and retention (EPR) effect and the remainder distributes into healthy tissues, causing side effects. Thus to improve the efficacy of PDT, research is currently focused on the development of specific receptor based photosynthetic nanocarrier drugs, which promotes the active uptake and absorption of PS drugs in tumour sites only, avoiding unwanted side effects. The aim of this review is to focus on current non-targeted passive versus specifically active targeted PS nanoparticle drug delivery systems, that have been investigated for the PDT treatment of lung cancer and so to deduce its efficacy and recent advancements.

AB - Previously, we have demonstrated that the transplantation of autologous mitochondria is cardioprotective. No immune or autoimmune response was detectable following the single injection of autologous mitochondria. To expand the therapeutic potential and safety of mitochondrial transplantation, we now investigate the immune response to single and serial injections of syngeneic and allogeneic mitochondria delivered by intraperitoneal injection. Our results demonstrate that there is no direct or indirect, acute or chronic alloreactivity, allorecognition or damage-associated molecular pattern molecules (DAMPs) reaction to single or serial injections of either syngeneic or allogeneic mitochondria. PMID- 29588219 TI - Exercise-induced reductions in mitochondrial ADP sensitivity contribute to the induction of gene expression and mitochondrial biogenesis through enhanced mitochondrial H2O2 emission. AB - Acute exercise rapidly induces mitochondrial gene expression, however, the intracellular events regulating this process remain incompletely understood. The purpose of this study was to determine whether reductions in mitochondrial ADP sensitivity during exercise have a biological role in regulating mitochondrial derived reactive oxygen species (ROS) production and the induction of mitochondrial biogenesis. Mitochondrial creatine kinase wildtype (WT) and knockout (KO) mice have divergent responses in ADP sensitivity during exercise, and we therefore used these mice to determine the relationship between mitochondrial ADP sensitivity, ROS production, and mitochondrial adaptations to exercise. In WT mice, acute exercise reduced mitochondrial ADP respiratory sensitivity and the ability of ADP to suppress ROS production, while increasing mitochondrial gene transcription (PGC-1alpha, PGC-1beta and PDK4). In stark contrast, in KO mice, exercise increased ADP sensitivity, reduced mitochondrial ROS emission, and did not induce gene transcription. Despite the divergence in mRNA responses, exercise similarly induced calcium/calmodulin-dependent protein kinase II (CaMKII) and AMP-activated protein kinase (AMPK) phosphorylation in WT and KO mice, however only WT mice were associated with redox stress (4HNE). These data implicate acute changes in ADP sensitivity in mitochondrial adaptations to exercise. To further examine this we chronically exercise trained mice. While training increased mitochondrial content and reduced ADP sensitivity in WT mice, KO mice did not exhibit adaptations to exercise. Combined, these data suggest that exercise-induced attenuations in mitochondrial ADP sensitivity mediate redox signals that contribute to the induction of acute and chronic mitochondrial adaptations.

AB - Metastasis is the leading cause of mortality in patients with highly invasive cancers and, as such, is a major problem for medicine. It has been increasingly recognized that cancer-related inflammation plays an important role in promoting invasion and the metastatic process in which cell motility and upregulation of proteolytic enzymes are crucial events. TNFalpha is a proinflammatory cytokine known to stimulate synthesis of MMP9, a zinc- and calcium-dependent endopeptidase contributing to the regulation of ECM remodeling and cell signaling. However, the precise molecular mechanism of TNFalpha-induced MMP9 gene expression in cancers is still not fully understood. This study shows that TNFalpha-induced cell migration and invasion involve ERK1/2-dependent up-regulation of CDKN1A/p21 expression in highly aggressive breast cancer cells and that CDKN1A/p21 plays an important regulatory role in TNFalpha-induced MMP9 gene expression, indicating an unknown function of CDKN1A/p21 as a regulator of proteolytic activity in cancer cells. PMID- 29588221 TI - A brief period of sleep deprivation causes spine loss in the dentate gyrus of mice. AB - Sleep and sleep loss have a profound impact on hippocampal function, leading to memory impairments. Modifications in the strength of synaptic connections directly influences neuronal communication, which is vital for normal brain function, as well as the processing and storage of information. In a recently published study, we found that as little as five hours of sleep deprivation impaired hippocampus-dependent memory consolidation, which was accompanied by a reduction in dendritic spine numbers in hippocampal area CA1. Surprisingly, loss of sleep did not alter the spine density of CA3 neurons. Although sleep deprivation has been reported to affect the function of the dentate gyrus, it is unclear whether a brief period of sleep deprivation impacts spine density in this region. Here, we investigated the impact of a brief period of sleep deprivation on dendritic structure in the dentate gyrus of the dorsal hippocampus. We found that five hours of sleep loss reduces spine density in the dentate gyrus with a prominent effect on branched spines. Interestingly, the inferior blade of the dentate gyrus seems to be more vulnerable in terms of spine loss than the superior blade. This decrease in spine density predominantly in the inferior blade of the dentate gyrus may contribute to the memory deficits observed after sleep loss, as structural reorganization of synaptic networks in this subregion is fundamental for cognitive processes. PMID- 29588222 TI - The transformation of multi-sensory experiences into memories during sleep. AB - Our everyday lives present us with a continuous stream of multi-modal sensory inputs. While most of this information is soon forgotten, sensory information associated with salient experiences can leave long-lasting memories in our minds. Extensive human and animal research has established that the hippocampus is critically involved in this process of memory formation and consolidation. However, the underlying mechanistic details are still only partially understood. Specifically, the hippocampus has often been suggested to encode information during experience, temporarily store it, and gradually transfer this information to the cortex during sleep. In rodents, ample evidence has supported this notion in the context of spatial memory, yet whether this process adequately describes the consolidation of multi-sensory experiences into memories is unclear. Here, focusing on rodent studies, I examine how multi-sensory experiences are consolidated into long term memories by hippocampal and cortical circuits during sleep. I propose that in contrast to the classical model of memory consolidation, the cortex is a "fast learner" that has a rapid and instructive role in shaping hippocampal-dependent memory consolidation. The proposed model may offer mechanistic insight into memory biasing using sensory cues during sleep. PMID- 29588224 TI - Dissociations of conscious and unconscious perception in TMS-induced blindsight. AB - As with some patients with primary visual cortex (V1) damage, transcranial magnetic stimulation (TMS) over V1 reliably induces blindsight, whereby observers can correctly discriminate the attributes of visual stimuli despite being unable to detect them. This TMS-induced blindsight has been demonstrated to reflect a form of unconscious vision that relies upon different neural pathways than with conscious vision. However, the timing of the neural processes mediating TMS induced blindsight has been unclear, especially when considering suggestions that TMS interferes with feedback processes to V1 that mediate conscious visual perception. To better elucidate the neural mechanisms that give rise to blindsight, we tested TMS-induced blindsight for the orientation of visual stimuli across a range of stimulus onset asynchronies (SOAs) to assess how different latencies of visual cortex disruption, relative to a visual stimulus, affect detection rates and forced-choice discrimination accuracy. At all TMS latencies, including at SOAs with substantial visual suppression from TMS, discrimination performance was significantly above-chance, demonstrating the consistency of TMS-induced blindsight. Crucially, we observed two windows of maximum visual suppression from TMS at SOAs between 65 and 105 ms, but consistent above-chance discrimination performance accuracy across these windows. However, at longer SOAs, detection and discrimination covaried, suggesting a dependency of discrimination performance on detection only when detection rates exceed threshold levels of normal vision. Taken together, these results indicate that unconscious discrimination occurs independently of detection, including at TMS intervals that optimally interfere with conscious visual perception. They further suggest that forced-choice discrimination is less dependent on feedback processes to V1 than visual awareness and that TMS-induced blindsight is not the same as near-threshold vision. PMID- 29588223 TI - Translation, adaptation and psychometric validation of the Good Perioperative Nursing Care Scale (GPNCS) with surgical patients in perioperative care. AB - AIM: To test the psychometric validity of the Good Perioperative Nursing Care Scale (GPNCS), a self-administered questionnaire, following translation and adaptation. INTRODUCTION: Patients' satisfaction with and experience of nursing care in orthopaedic or perioperative settings are currently not routinely measured and few standardized patient-reported experience measurement tools exist for these settings. MATERIALS AND METHODS: Cross-sectional survey. The 34 question, seven-factor questionnaire was translated, adapted, and face-validated; the translated version was then validated with a group of surgical patients in perioperative settings. The internal consistency of the translated version was validated and tested using confirmatory factor analysis combined with Cronbach's alpha. RESULTS: In the orthopaedic department of a regional public hospital, 361 acute, traumatic and elective surgical patients were screened for eligibility; 215 were included. The full-scale model fit estimates were moderate. Factor loadings typically ranged from 0.65 to 0.97, except for the questions concerning Technical Skills (0.38-0.63) and Nursing Process (0.28). The Cronbach's alpha value for the total scale score was 0.92, with subfactors ranging from 0.72 to 0.87. CONCLUSION: Providing evidence for quality, or lack thereof, the Danish version of the GPNCS is a valid tool for measuring surgical patients' experiences with perioperative nursing care. The electronic version proved practical. RELEVANCE TO CLINICAL PRACTICE: The validated Danish version of the tool will help healthcare professionals to identify areas of nursing care that need improvement, facilitate international benchmarking of units and enable comparison of care quality, nationally and internationally. PMID- 29588225 TI - Identification of task sets within and across stimulus modalities. AB - Previous studies have shown that task sets can be identified from functional magnetic resonance imaging (fMRI) data. However, these results may be partially confounded by differences in stimulus features associated with the different tasks. We disentangle stimulus modality and task features by presenting the same stimulus while varying task, and conversely, presenting different stimuli using the same task. Analyses were conducted on fMRI data previously collected on twenty participants who made either affective or semantic judgements of the same music pieces or the same silent video clips (Kim et al., 2017). Holding stimuli constant, task set was identified from fMRI data across individuals from both task activation data and functional connectivity data. Thus, we were able to identify whether participants made affective or semantic judgments when exposed to identical stimuli based on the task activation and functional connectivity data from other participants. Moreover, task set was successfully identified for cross-modal prediction in which stimuli in the training set bore no resemblance to those in the test set (e.g., using videos data to predict task for music data). Brain regions that were sensitive to tasks irrespective of sensory modality were identified by univariate and searchlight analyses of fMRI data. Consistent with a frontal-parietal network, middle frontal gyrus, inferior parietal gyrus, mid-cingulate cortex, and superior temporal sulcus were found to be key regions distinguishing the two task sets. PMID- 29588226 TI - The current status of the magnocellular theory of developmental dyslexia. AB - Some people doubt that the concept of developmental dyslexia (DD) is useful at all because the phonological weaknesses seen in DD cannot be distinguished from those found in every person with poor reading skills, whatever their cause. Here I argue that true DD is characterised by poor temporal processing, hence impaired visual and auditory sequencing, that is caused by impaired development of transient/magnocellular (M-) systems throughout the brain. These deficits can be measured in order to distinguish the causes of the phonological weaknesses in DD from those causing similar deficits in other types of poor reading. Importantly this knowledge can be exploited to develop effective improvements in treatment. The evidence for impaired visual magnocellular function in many, if not all, people with dyslexia is now overwhelming; it is supported not only by psychophysical tests of M- function, but also by electrophysiological, eye movement, attentional, imaging, interventional and genetic findings. Analogously, auditory temporal processing is mediated by auditory transient, 'magnocellular', processing systems, and evidence is accumulating persuasively that this system is also impaired in dyslexics. I briefly introduce the idea that 'motor magnocellular systems' may also be impaired in dyslexia, then consider genetic, immunological and nutritional factors that interact to cause the impaired magnocellular phenotype. I then discuss why the dyslexic phenotype is so common by speculating about what strengths it might confer that would maintain the responsible genes in the human genome. PMID- 29588227 TI - Resting-state functional connectivity predicts the ability to adapt arm reaching in a robot-mediated force field. AB - Motor deficits are common outcomes of neurological conditions such as stroke. In order to design personalised motor rehabilitation programmes such as robot assisted therapy, it would be advantageous to predict how a patient might respond to such treatment. Spontaneous neural activity has been observed to predict differences in the ability to learn a new motor behaviour in both healthy and stroke populations. This study investigated whether spontaneous resting-state functional connectivity could predict the degree of motor adaptation of right (dominant) upper limb reaching in response to a robot-mediated force field. Spontaneous neural activity was measured using resting-state electroencephalography (EEG) in healthy adults before a single session of motor adaptation. The degree of beta frequency (beta; 15-25 Hz) resting-state functional connectivity between contralateral electrodes overlying the left primary motor cortex (M1) and the anterior prefrontal cortex (aPFC) could predict the subsequent degree of motor adaptation. This result provides novel evidence for the functional significance of resting-state synchronization dynamics in predicting the degree of motor adaptation in a healthy sample. This study constitutes a promising first step towards the identification of patients who will likely gain most from using robot-mediated upper limb rehabilitation training based on simple measures of spontaneous neural activity. PMID- 29588228 TI - Neural oscillations during conditional associative learning. AB - Associative learning requires mapping between complex stimuli and behavioural responses. When multiple stimuli are involved, conditional associative learning is a gradual process with learning based on trial and error. It is established that a distributed network of regions track associative learning, however the role of neural oscillations in human learning remains less clear. Here we used scalp EEG to test how neural oscillations change during learning of arbitrary visuo-motor associations. Participants learned to associative 48 different abstract shapes to one of four button responses through trial and error over repetitions of the shapes. To quantify how well the associations were learned for each trial, we used a state-space computational model of learning that provided a probability of each trial being correct given past performance for that stimulus, that we take as a measure of the strength of the association. We used linear modelling to relate single-trial neural oscillations to single-trial measures of association strength. We found frontal midline theta oscillations during the delay period tracked learning, where theta activity was strongest during the early stages of learning and declined as the associations were formed. Further, posterior alpha and low-beta oscillations in the cue period showed strong desynchronised activity early in learning, while stronger alpha activity during the delay period was seen as associations became well learned. Moreover, the magnitude of these effects during early learning, before the associations were learned, related to improvements in memory seen on the next presentation of the stimulus. The current study provides clear evidence that frontal theta and posterior alpha/beta oscillations play a key role during associative memory formation. PMID- 29588229 TI - Microstructural imaging of human neocortex in vivo. AB - The neocortex of the human brain is the seat of higher brain function. Modern imaging techniques, chief among them magnetic resonance imaging (MRI), allow non invasive imaging of this important structure. Knowledge of the microstructure of the neocortex has classically come from post-mortem histological studies of human tissue, and extrapolations from invasive animal studies. From these studies, we know that the scale of important neocortical structure spans six orders of magnitude, ranging from the size of axonal diameters (microns), to the size of cortical areas responsible for integrating sensory information (centimetres). MRI presents an opportunity to move beyond classical methods, because MRI is non invasive and MRI contrast is sensitive to neocortical microstructure over all these length scales. MRI thus allows inferences to be made about neocortical microstructure in vivo, i.e. MRI-based in vivo histology. We review recent literature that has applied and developed MRI-based in vivo histology to probe the microstructure of the human neocortex, focusing specifically on myelin, iron, and neuronal fibre mapping. We find that applications such as cortical parcellation (using [Formula: see text] maps as proxies for myelin content) and investigation of cortical iron deposition with age (using [Formula: see text] maps) are already contributing to the frontiers of knowledge in neuroscience. Neuronal fibre mapping in the cortex remains challenging in vivo, but recent improvements in diffusion MRI hold promise for exciting applications in the near future. The literature also suggests that utilising multiple complementary quantitative MRI maps could increase the specificity of inferences about neocortical microstructure relative to contemporary techniques, but that further investment in modelling is required to appropriately combine the maps. In vivo histology of human neocortical microstructure is undergoing rapid development. Future developments will improve its specificity, sensitivity, and clinical applicability, granting an ever greater ability to investigate neuroscientific and clinical questions about the human neocortex. PMID- 29588230 TI - Associations between maternal cytokine levels during gestation and measures of child cognitive abilities and executive functioning. AB - Preclinical studies demonstrate that environmentally-induced alterations in inflammatory cytokines generated by the maternal and fetal immune system can significantly impact fetal brain development. Yet, the relationship between maternal cytokines during gestation and later cognitive ability and executive function remains understudied. Children (n = 246) were born of mothers enrolled in the Newborn Epigenetic Study - a prospective pre-birth cohort in the Southeastern US. We characterized seven cytokines [IL-1beta, IL-4,IL-6, IL-12p70, IL-17A, tumor necrosis factor-alpha (TNFalpha), and interferon-gamma (IFNgamma)] and one chemokine (IL-8) from maternal plasma collected during pregnancy. We assessed children's cognitive abilities and executive functioning at a mean age of 4.5 (SD = 1.1) years. Children's DAS-II and NIH toolbox scores were regressed on cytokines and the chemokine, controlling for maternal age, race, education, body mass index, IQ, parity, smoking status, delivery type, gestational weeks, and child birth weight and sex. Higher IL-12p70 (betaIL-12p70 = 4.26, p = 0.023) and IL-17A (betaIL-17A = 3.70, p = 0.042) levels were related to higher DAS-II GCA score, whereas higher IL-1beta (betaIL-1B = -6.07, p = 0.003) was related to lower GCA score. Higher IL-12p70 was related to higher performance on NIH toolbox measures of executive functions related to inhibitory control and attention (betaIL-12p70 = 5.20, p = 0.046) and cognitive flexibility (betaIL-12p70 = 5.10, p = 0.047). Results suggest that dysregulation in gestational immune activity are associated with child cognitive ability and executive functioning. PMID- 29588231 TI - Developmental psychoneuroimmunology grows up. PMID- 29588232 TI - The effect of beta-adrenergic blockade on inflammatory and cardiovascular responses to acute mental stress. AB - Acute mental stress elicits increases in plasma cytokine concentrations in humans, but the underlying mechanisms remain poorly understood. We assessed the impact of beta-adrenergic blockade on plasma interleukin 6 (IL-6) and IL-1 receptor antagonist (IL-1Ra) responses in a parallel group, double-blind randomised placebo-controlled trial involving 64 healthy young adult volunteers. Participants were administered 80 mg slow-release propranolol or placebo daily for 7 days before the stress testing session in which responses to 3 behavioural challenges (public speaking, mirror tracing, mental arithmetic) were evaluated. Propranolol administration was associated with reduced baseline levels of heart rate and IL-1Ra, and systolic blood pressure (BP) in men. Tasks stimulated increased plasma IL-6 concentrations sampled 45 min and 75 min after challenge, but these responses were blocked by propranolol in men (p < 0.001). Propranolol did not influence IL-6 responses in women, or IL-1Ra in either sex. Blood pressure and heart rate increased markedly during the tasks, but there was no differential stress reactivity in propranolol and placebo conditions. The results of the study support a role of sympathetic nervous system activation in stimulating acute IL-6 responses to stress, but only in men. The reasons for the differences between men and women remain to be resolved. PMID- 29588234 TI - Metabolic engineering tools in model cyanobacteria. AB - Developing sustainable routes for producing chemicals and fuels is one of the most important challenges in metabolic engineering. Photoautotrophic hosts are particularly attractive because of their potential to utilize light as an energy source and CO2 as a carbon substrate through photosynthesis. Cyanobacteria are unicellular organisms capable of photosynthesis and CO2 fixation. While engineering in heterotrophs, such as Escherichia coli, has result in a plethora of tools for strain development and hosts capable of producing valuable chemicals efficiently, these techniques are not always directly transferable to cyanobacteria. However, recent efforts have led to an increase in the scope and scale of chemicals that cyanobacteria can produce. Adaptations of important metabolic engineering tools have also been optimized to function in photoautotrophic hosts, which include Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9, 13C Metabolic Flux Analysis (MFA), and Genome Scale Modeling (GSM). This review explores innovations in cyanobacterial metabolic engineering, and highlights how photoautotrophic metabolism has shaped their development. PMID- 29588233 TI - Postpartum increases in cerebral edema and inflammation in response to placental ischemia during pregnancy. AB - Reduced placental blood flow results in placental ischemia, an initiating event in the pathophysiology of preeclampsia, a hypertensive pregnancy disorder. While studies show increased mortality risk from Alzheimer's disease, stroke, and cerebrovascular complications in women with a history of preeclampsia, the underlying mechanisms are unknown. During pregnancy, placental ischemia, induced by reducing uterine perfusion pressure (RUPP), leads to cerebral edema and increased blood-brain barrier (BBB) permeability; however whether these complications persist after delivery is not known. Therefore, we tested the hypothesis that placental ischemia contributes to postpartum cerebral edema and neuroinflammation. On gestational day 14, time-pregnant Sprague Dawley rats underwent Sham (n = 10) or RUPP (n = 9) surgery and brain tissue collected 2 months post-delivery. Water content increased in posterior cortex but not hippocampus, striatum, or anterior cerebrum following RUPP. Using a rat cytokine multi-plex kit, posterior cortical IL-17, IL-1alpha, IL-1beta, Leptin, and MIP2 increased while hippocampal IL-4, IL-12(p70) and RANTES increased and IL-18 decreased following RUPP. Western blot analysis showed no changes in astrocyte marker, Glial Fibrillary Acidic Protein (GFAP); however, the microglia marker, ionized calcium binding adaptor molecule (Iba1) tended to increase in hippocampus of RUPP-exposed rats. Immunofluorescence staining revealed reduced number of posterior cortical microglia but increased activated (Type 4) microglia in RUPP. Astrocyte number increased in both regions but area covered by astrocytes increased only in posterior cortex following RUPP. BBB-associated proteins, Claudin-1, Aquaporin-4, and zonular occludens-1 expression were unaltered; however, posterior cortical occludin decreased. These results suggest that 2 months postpartum, neuroinflammation, along with decreased occludin expression, may partly explain posterior cortical edema in rats with history of placental ischemia. PMID- 29588235 TI - A Comparison of Computed Tomography-Based Scales with and without Consideration of the Presence or Absence of Intraventricular Hemorrhage in Patients with Aneurysmal Subarachnoid Hemorrhage. AB - OBJECTIVE: There has been controversy as to whether intraventricular hemorrhage (IVH) after aneurysmal subarachnoid hemorrhage (SAH) contributes to angiographic cerebral vasospasm (aCV) and delayed cerebral ischemia (DCI). Computed tomography based SAH scales that did and did not consider IVH were compared in terms of ability to predict aCV, DCI, and outcome. METHODS: We reviewed 390 patients with ruptured aneurysms who had been treated surgically by day 3 by the same surgeon (T.I.). aCV was graded as 0-4. Outcome at 6 months was classified using the Glasgow Outcome Scale. Inagawa SAH grades and scores, for which only SAH was evaluated, were compared with scales that evaluated both SAH and IVH (Fisher, Claassen, and Frontera grades, and Hijdra score). The area under the receiver operating characteristic curve was calculated to compare severe aCV (grade 3-4), DCI, or poor outcome (Glasgow Outcome Scale score 1-3). RESULTS: The Inagawa grade showed constant and significant intergrade differences in both aCV and DCI. The Inagawa grade area under the receiver operating characteristic curve values were highest among the scales examined. In the Fisher, Claassen, and Frontera grades, IVH was unlikely to be related to aCV and DCI. There was no significant difference in aCV grade or DCI occurrence between the Inagawa and Hijdra scores. In contrast, the presence of IVH was significantly associated with poor outcome. CONCLUSIONS: In patients with aneurysmal SAH, IVH is an important factor affecting patient outcome, whereas computed tomography-based SAH scales that do not consider IVH are superior to scales that do consider it for prediction of aCV or DCI. PMID- 29588236 TI - Predicting Successful Treatment of Intracranial Aneurysms with the Pipeline Embolization Device Through Meta-Regression. AB - OBJECTIVE: To conduct meta-regression for the identification of clinically meaningful characteristics that can predict successful treatment of intracranial aneurysms with the Pipeline Embolization Device (PED). METHODS: Using the key word "Pipeline Embolization Device" and prespecified eligibility criteria, we searched PubMed and EMBASE and identified 105 original research articles (10,813 patients) published or in press (April 6, 2011, to December 31, 2016) focused on safety and/or effectiveness of PED. We constructed meta-regression models to identify predictors of 3 measures of PED treatment success, specifically rates of aneurysm occlusion, modified Rankin Scale score, and death. Rates were loge transformed, and the adjusted R2 statistic was reported for each model. RESULTS: Aneurysm morphology and type accounted for substantial variation in 1-year aneurysm occlusion rate (14 studies with 689 patients; Radj2 = 88.91%). By contrast, predictors of 6-months aneurysm occlusion rate (aneurysm location, aneurysm type; 24 studies with 1321 patients; Radj2 = 31.67%) and aneurysm occlusion rate at unspecified follow-up time (year of publication, mean duration of angiographic follow-up; 34 studies with 1663 patients, Radj2 = 42.82%) accounted for less variability. Few predictors were identified for death rate (number of patients, aneurysm morphology; 34 studies with 6463 patients, Radj2 = 50.69%) or modified Rankin Scale score <=2 (year of publication, mean age, aneurysm morphology; 14 studies with 556 patients, Radj2 = 100%). CONCLUSIONS: Few clinically meaningful characteristics appear to be relevant as predictors of the selected measures of PED treatment success. Future studies should attempt to identify additional predictors while focusing on aneurysm morphology as a key predictor of PED outcomes. PMID- 29588237 TI - John C. Vangilder (1935-2007): Neurosurgical Leader and Founder of the Department of Neurosurgery at the University of Iowa. AB - John C. VanGilder, the former professor and chairman of neurosurgery at The University of Iowa died on August 27, 2007 after making a lasting impact to the field of neurosurgery both in the United States and abroad. In this manuscript, we review VanGilder's life and achievements. VanGilder was born in 1935 in West Virginia and received his undergraduate education at West Virginia University in Morgantown. He studied medicine at the University of West Virginia, completing his final 2 years at the University of Pittsburgh, and after serving in the U.S. military, completed his neurosurgical training at Washington University in St. Louis. He was appointed to faculty positions first at Yale University and later at The University of Iowa, where he became professor and later chairman of the Division of Neurosurgery. VanGilder also served as president of the Society of Neurological Surgeons (1997-1998), president of the Neurosurgical Society of America (1998-1999), chairman of the American Board of Neurological Surgery (1997 1998), and vice president of the American Academy of Neurological Surgery. At The University of Iowa, VanGilder played a key role in the transition of the Division of Neurosurgery to a Department of Neurosurgery and mentored several neurosurgeons who would go on to become department chairmen or make other important neurosurgical contributions at other medical schools in the United States. PMID- 29588238 TI - Surgery for Multisegment Thoracolumbar Mild Osteoporotic Fractures: Revised Assessment System of Thoracolumbar Osteoporotic Fracture. AB - OBJECTIVE: To examine the Assessment System of Thoracolumbar Osteoporotic Fracture (ASTLOF), which can effectively guide the treatment of single-segmental thoracolumbar osteoporotic vertebral compression fractures but fails to guide the treatment of multisegmental thoracolumbar mild osteoporotic vertebral compression fracture (MSTMOVCF). METHODS: A prospective case series study was designed to enroll elderly patients with MSTMOVCF who had been treated with percutaneous kyphoplasty/percutaneous vertebroplasty (PKP/PVP) from June 2013 to June 2016. Surgery indication was based on revised ASTLOF. Visual analog scale and Oswestry Disability Index (ODI) scores were used to evaluate the postoperative improvement of back pain, and clinical effects were assessed according to the 36-Item Short Form Health Survey. Some imaging measures, such as height of anterior and middle column and Beck value, were measured before the operation and 12 months after the operation. Complications also were collected. RESULTS: A total of 193 patients underwent PKP/PVP surgery. At postoperative 2 days, 3 months, and 1-year follow up, whereas VAS and ODI scores decreased (P < 0.0001, for all) significantly as well as SF-36, the height of anterior and middle column increased (P < 0.0001, for all) compared with preoperation. Beck value at 1-year follow-up was greater than preoperation (P = 0.001). The improvement rate of ODI was 86.4 +/- 8.3%. CONCLUSIONS: Patients with MSTMOVCF who undergo surgery with PKP/PVP can achieve great clinical results. Patients with the sum of revised ASTLOF scores of multiple injured vertebrae >=5 should be recommended for surgery. The consistency and repeatability of the revised ASTLOF need further study. PMID- 29588239 TI - Coagulation Alteration and Deep Vein Thrombosis in Brain Tumor Patients During the Perioperative Period. AB - OBJECTIVE: To explore coagulation function in patients with brain tumors before and after craniotomy and tumor resection and to analyze its correlation with deep vein thrombosis (DVT). METHODS: This study enrolled 133 consecutive patients with brain tumors. Coagulation evaluation and limb venous ultrasonography were performed before and after surgery. Clinical characteristics and dynamic changes in coagulation parameters were recorded, and their correlations with DVT were analyzed. RESULTS: The incidence of postoperative DVT in patients with brain tumors was 10.5%. The average age of patients with DVT was older compared with patients without DVT (63.21 +/- 11.21 years vs. 50.24 +/- 11.95 years, P < 0.001), and the incidence of hepatitis B (21% vs. 4%, P = 0.035) was higher in patients with DVT compared with patients without DVT. D-dimer and fibrinogen were the most variable parameters during the perioperative period. In patients with DVT, D-dimer levels displayed a "zigzagging-rise" trend and were significantly higher than levels in patients without DVT. Platelet levels displayed a "first descend-then-rise" trend and were significantly lower in patients with DVT on the second and third postoperative days. CONCLUSIONS: In patients with brain tumors, D-dimer and fibrinogen were elevated postoperatively, manifesting as hypercoagulability. Postoperative DVT was correlated with aging and hepatitis B. A "zigzagging-rise" trend of D-dimer and a "sharp-descent" trend of platelets in the early postoperative period might predict DVT in patients with brain tumors. PMID- 29588240 TI - Superficial Temporal Artery-Superior Cerebellar Artery Bypass with Anterior Petrosectomy. AB - BACKGROUND: Superficial temporal artery (STA) to superior cerebellar artery (SCA) bypass is associated with a relatively high risk of surgical complications, such as hematoma and/or edema caused by temporal lobe retraction. Therefore, the right side is typically used to avoid retraction of the left temporal lobe. In this report, we present a case of left STA-SCA bypass with anterior petrosectomy to avoid retraction of dominant-side temporal lobe and describe the surgical technique in detail. CASE DESCRIPTION: A 69-year-old man presented with gradual worsening of dysarthria and gait disturbance. Magnetic resonance imaging showed no signs of acute infarction, but digital subtraction angiography showed severe stenosis of basilar artery and faint flow in the distal basilar artery. On 3 dimensional computed tomography angiography, posterior communicating arteries were not visualized; we could identify the left SCA, but not the right SCA. Despite dual antiplatelet therapy, a small fresh brainstem infarct was detected 10 days after admission. To avert fatal brainstem infarction and further enlargement of the infarct, we performed left STA-SCA bypass with anterior petrosectomy to avoid retraction of the dominant-side temporal lobe. Postoperative imaging revealed no new lesions, such as infarction or temporal lobe contusional hematoma, and confirmed the patency of the bypass. Postoperative single-photon emission computed tomography demonstrated improved cerebral blood flow in the posterior circulation. The patient was transferred to another hospital for rehabilitation. CONCLUSIONS: This method helps minimize the risk of injury to the temporal lobe, especially that of the dominant side. PMID- 29588242 TI - Primary Spinal Malignant Mesothelioma: A Case Report and Literature Review. AB - BACKGROUND: Malignant mesotheliomas are aggressive and rapidly fatal neoplasms arising from the mesothelial cells. The most common sites of origin are the pleural and peritoneal cavities; the pericardium and the tunica vaginalis are infrequently involved, and malignant mesothelioma in the spinal canal is extremely rare. Here we report a case of primary spinal malignant mesothelioma. We also report the results of a literature search conducted in PubMed with specific key terms, inclusion criteria, and exclusion criteria, with a comparison of elected case studies and case series, and statistical analysis as appropriate. CASE DESCRIPTION: A 35-year-old man presented with a 3-month history of swelling and pain in the left lower extremity. Neurologic examination revealed a loss of sensation below the L5 dermatome. Magnetic resonance imaging (MRI) showed a mass at the L4-5 level. A diagnosis of schwannoma was suspected, and surgical resection was performed. Histopathological findings were consistent with sarcomatoid malignant mesothelioma. Thoracic and whole-abdomen computed tomography yielded normal results. The patient refused adjuvant radiotherapy or chemotherapy. Positron emission tomography-computed tomography performed at 3 months postoperatively showed no abnormality. At 8 months postoperatively, the patient developed back pain and difficulty with defecation; MRI demonstrated tumor recurrence. During a second operation, invasion of the vertebra and cauda equina was noted. A subtotal resection was achieved, and the pain was partially alleviated. Two months later, the patient succumbed to a traffic accident. CONCLUSIONS: Spinal malignant mesothelioma is an extremely rare but highly aggressive entity. Preoperative identification is challenging, and definitive diagnosis depends on histopathological evidence. Surgical resection can help relieve the symptoms, but the overall prognosis is poor. PMID- 29588241 TI - Facet Joint Fixation and Anterior, Direct Lateral, and Transforaminal Lumbar Interbody Fusions for Treatment of Degenerative Lumbar Disc Diseases: Retrospective Cohort Study of a New Minimally Invasive Technique. AB - BACKGROUND: Anterior, direct lateral, and transforaminal lumbar interbody fusions (ALIF, DLIF, and TLIF) are usually combined with posterior fixation to treat degenerative spinal diseases. Outcomes of ALIF, TLIF, or DLIF combined with a new wedge-shaped interfacet cage plate have not been reported. We assessed early clinical outcomes of patients treated with interbody fusion and facet fixation using a titanium wedge-shaped cage plate. METHODS: This retrospective observational cohort study included patients (n = 80) who underwent 1-level interbody fusion and facet joint fixation via ALIF (n = 24) or DLIF (n = 26) with bilateral facet fixation or TLIF with ipsilateral pedicle screws and contralateral facet fixation (n = 30). Duration of surgery, estimated blood loss, pain (visual analog scale), Oswestry Disability Index (ODI) scores, and Macnab score were assessed up to 12 months after surgery. RESULTS: All patients had a significant decrease in pain scores (P < 0.01) and an increase in ODI scores (P < 0.01), without significant differences between treatment groups. Most surgical outcomes were excellent or good (n = 75, 93.8%) with 5 patients (6.2%) having satisfactory outcomes. Within 2 months, all patients returned to their previous work (66, 82.5%) or lighter work (14, 17.5%). Two patients had fusion failure requiring reoperation. CONCLUSIONS: Facet fixation with the wedge-shaped cage plate was associated with minimal soft tissue damage and a low level of postoperative pain. ALIF, DLIF, and TLIF combined with this technique showed good early postoperative clinical and radiologic outcomes. Further studies are needed to assess long-term results and compare them with other fusion methods. PMID- 29588243 TI - Clinical Outcomes of Isolated Congenital Aqueductal Stenosis. AB - INTRODUCTION: Hydrocephalus due to congenital aqueductal stenosis (CAS) has significant long-term clinical implications. Previous reports on outcomes after treatment of congenital hydrocephalus are heterogenous and lack specificity for the subgroup of patients with isolated aqueductal stenosis. METHODS: An institutional surgical database was queried for the time period of 2005-2013 for patients with the diagnosis of isolated CAS and >2 years of clinical follow-up. Medical history and neurodevelopmental outcomes were recorded. RESULTS: The institutional cohort consisted of 41 patients with isolated CAS who underwent cerebrospinal fluid diversion. At a mean follow-up of 5.9 years, 48.8% carried a diagnosis of epilepsy and 68% were developmentally delayed. Four patients were diagnosed with cerebral palsy (9.8%). In total, 78% of patients were shunt dependent, and the remainder had patent third ventriculostomies. Only 32% of patients in our cohort were neurologically normal after long-term follow-up despite contemporary management. CONCLUSIONS: Regardless of the initial treatment strategy, the age at diagnosis, or the timing of cerebrospinal fluid diversion after birth, patients with aqueductal stenosis have high rates of epilepsy, neurodevelopmental delay, and educational difficulties, and few are neurologically normal despite contemporary management. Investigation into in utero identification and correction of hydrocephalus may result in improved outcomes and warrants further investigation. PMID- 29588244 TI - Intracranial Epidural Metastases of Adrenal Pheochromocytoma: A Rare Entity. AB - BACKGROUND: Pheochromocytomas are uncommon neuroendocrine tumors of the adrenal medulla. Malignant behavior is seen in approximately 10% of these lesions, evidenced by distant metastasis to sites without chromaffin tissue. Here we report a rare case of intracranial epidural metastases of an adrenal pheochromocytoma in a 24-year-old man. CASE DESCRIPTION: The patient originally presented at age 10 years with adrenal pheochromocytoma and subsequently developed extensive metastatic bone and lung disease. He was monitored in the intervening years until recent imaging demonstrated an enlarging right parietal mass. On surgical resection of the parietal lesion, the tumor was highly vascularized and confined to the epidural space. CONCLUSIONS: To the best of our knowledge, this is the first reported case of metastatic epidural spread of pheochromocytoma without concomitant subdural or intraparenchymal extension.

PMID- 29588245 TI - Predicting Dural Tear in Compound Depressed Skull Fractures: A Prospective Multicenter Correlational Study. AB - BACKGROUND: Compound depressed skull fracture (DSF) is a neurosurgical emergency. Preoperative knowledge of dural status is indispensable for treatment decision making. This study aimed to determine predictors of dural tear from clinical and imaging characteristics in patients with compound DSF. METHODS: This prospective, multicenter correlational study in neurosurgical hospitals in Addis Ababa, Ethiopia, included 128 patients operated on from January 1, 2016, to October 31, 2016. Clinical, imaging, and intraoperative findings were evaluated. Univariate and multivariate analyses were used to establish predictors of dural tear. A logistic regression model was developed to predict probability of dural tear. Model validation was done using the receiver operating characteristic curve. RESULTS: Dural tear was seen in 55.5% of 128 patients. Demographics, injury mechanism, clinical presentation, and site of DSF had no significant correlation with dural tear. In univariate and multivariate analyses, depth of fracture depression (odds ratio 1.3, P < 0.001), pneumocephalus (odds ratio 2.8, P = 0.005), and brain contusions/intracerebral hematoma (odds ratio 5.5, P < 0.001) were significantly correlated with dural tear. We developed a logistic regression model (diagnostic test) to calculate probability of dural tear. Using the receiver operating characteristic curve, we determined the cutoff value for a positive test giving the highest accuracy to be 30% with a corresponding sensitivity of 93.0% and specificity of 43.9%. CONCLUSIONS: Dural tear in compound DSF can be predicted with 93.0% sensitivity using preoperative findings and may guide treatment decision making in resource-limited settings where risk of extensive cranial surgery outweighs the benefit.

PMID- 29588248 TI - Nonmalignant late cutaneous changes after allogeneic hematopoietic stem cell transplant in children. AB - BACKGROUND: There are limited pediatric data on nonmalignant cutaneous changes, including autoimmune conditions and permanent alopecia, after hematopoietic stem cell transplantation (HSCT). OBJECTIVE: We sought to characterize late cutaneous changes and associated risk factors after allogeneic HSCT in children. METHODS: A cross-sectional cohort study of pediatric HSCT recipients was performed at a single institution. All participants underwent a full skin examination. RESULTS: The median visit age was 13.8 years, with a median time post-HSCT of 3.6 years. Of 85 patients, 14% (n = 12) had vitiligo, 16% (n = 14) had psoriasis/sebopsoriasis, 25% (n = 21) had alopecia, and 6% (n = 5) had nail changes. Factors significantly associated with vitiligo included a history of chronic graft-versus-host disease (cGVHD), transplant indication of primary immunodeficiency, and younger age at transplant (<10 years of age). Fifty-two percent of patients with alopecia had androgenetic alopecia patterns. Factors significantly associated with alopecia included cGVHD, busulfan conditioning, and family history of early male pattern alopecia. All patients with nail changes had cGVHD. LIMITATIONS: The cross-sectional design did not allow time of onset identification. Histopathologic correlation was not performed. CONCLUSION: Pediatric HSCT recipients, particularly those with cGVHD, are at risk for developing nonmalignant late cutaneous changes. PMID- 29588249 TI - Risk of skin cancer in patients with HIV: A Danish nationwide cohort study. AB - BACKGROUND: The risk of skin cancer in patients with HIV has not been extensively studied. OBJECTIVE: We sought to determine the risk of skin cancer in patients with HIV and compare it with the risk in the background population. METHODS: In a matched, nationwide, population-based cohort study, we compared the risk of skin cancer in 4280 patients with HIV from the Danish HIV cohort study with a background population cohort, according to the level of immunosuppression and route of transmission. Primary outcomes were time to first basal cell carcinoma (BCC), squamous cell carcinoma (SCC), or malignant melanoma. RESULTS: Patients with HIV had an increased risk of BCC and SCC with incident rate ratios of 1.79 (95% confidence interval 1.43-2.22) and 5.40 (95% confidence interval 3.07-9.52), respectively, compared with the background population. We observed no increased risk of malignant melanoma. Low nadir CD4 cell count was associated with an increased risk of SCC. The increased risk of BCC among patients with HIV was restricted to men who had sex with men. LIMITATIONS: This study was observational and included a small number of patients with melanoma. CONCLUSION: Patients with HIV have an increased risk of BCC and SCC. Low nadir, but not current, CD4 cell count as a marker of immunosuppression was associated with an increased risk of SCC. PMID- 29588250 TI - A Novel Role for Lymphotactin (XCL1) Signaling in the Nervous System: XCL1 Acts via its Receptor XCR1 to Increase Trigeminal Neuronal Excitability. AB - Chemokines are known to have a role in the nervous system, influencing a range of processes including the development of chronic pain. To date there are very few studies describing the functions of the chemokine lymphotactin (XCL1) or its receptor (XCR1) in the nervous system. We investigated the role of the XCL1-XCR1 axis in nociceptive processing, using a combination of immunohistochemical, pharmacological and electrophysiological techniques. Expression of XCR1 in the rat mental nerve was elevated 3 days following chronic constriction injury (CCI), compared with 11 days post-CCI and sham controls. XCR1 co-existed with neuronal marker PGP9.5, leukocyte common antigen CD45 and Schwann cell marker S-100. In the trigeminal root and white matter of the brainstem, XCR1-positive cells co expressed the oligodendrocyte marker Olig2. In trigeminal subnucleus caudalis (Vc), XCR1 immunoreactivity was present in the outer laminae and was colocalized with vesicular glutamate transporter 2 (VGlut2), but not calcitonin gene-related peptide (CGRP) or isolectin B4 (IB4). Incubation of brainstem slices with XCL1 induced activation of c-Fos, ERK and p38 in the superficial layers of Vc, and enhanced levels of intrinsic excitability. These effects were blocked by the XCR1 antagonist viral CC chemokine macrophage inhibitory protein-II (vMIP-II). This study has identified for the first time a role for XCL1-XCR1 in nociceptive processing, demonstrating upregulation of XCR1 at nerve injury sites and identifying XCL1 as a modulator of central excitability and signaling via XCR1 in Vc, a key area for modulation of orofacial pain, thus indicating XCR1 as a potential target for novel analgesics. PMID- 29588251 TI - Effects of Class II-Selective Histone Deacetylase Inhibitor on Neuromuscular Function and Disease Progression in SOD1-ALS Mice. AB - Emerging evidence indicates that transcriptome alterations due to epigenetic deregulation concur to ALS pathogenesis. Accordingly, pan-histone deacetylase (HDAC) inhibitors delay ALS development in mice, but these compounds failed when tested in ALS patients. Possibly, lack of selectivity toward specific classes of HDACs weakens the therapeutic effects of pan-HDAC inhibitors. Here, we tested the effects of the HDAC Class II selective inhibitor MC1568 on disease evolution, motor neuron survival as well as skeletal muscle function in SOD1G93A mice. We report that HDACs did not undergo expression changes during disease evolution in isolated motor neurons of adult mice. Conversely, increase in specific Class II HDACs (-4, -5 and -6) occurs in skeletal muscle of mice with severe neuromuscular impairment. Importantly, treatment with MC1568 causes early improvement of motor performances that vanishes at later stages of disease. Notably, motor improvement is not paralleled by reduced motor neuron degeneration but by increased skeletal muscle electrical potentials, reduced activation of mir206/FGFBP1-dependent muscle reinnervation signaling, and increased muscle expression of myogenic genes. PMID- 29588252 TI - TLQP Peptides in Amyotrophic Lateral Sclerosis: Possible Blood Biomarkers with a Neuroprotective Role. AB - While the VGF-derived TLQP peptides have been shown to prevent neuronal apoptosis, and to act on synaptic strengthening, their involvement in Amyotrophic Lateral Sclerosis (ALS) remains unclarified. We studied human ALS patients' plasma (taken at early to late disease stages) and primary fibroblast cultures (patients vs controls), in parallel with SOD1-G93A transgenic mice (taken at pre , early- and late symptomatic stages) and the mouse motor neuron cell line (NSC 34) treated with Sodium Arsenite (SA) to induce oxidative stress. TLQP peptides were measured by enzyme-linked immunosorbent assay, in parallel with gel chromatography characterization, while their localization was studied by immunohistochemistry. In controls, TLQP peptides, including forms compatible with TLQP-21 and 62, were revealed in plasma and spinal cord motor neurons, as well as in fibroblasts and NSC-34 cells. TLQP peptides were reduced in ALS patients' plasma starting in the early disease stage (14% of controls) and remaining so at the late stage (16% of controls). In mice, a comparable pattern of reduction was shown (vs wild type), in both plasma and spinal cord already in the pre symptomatic phase (about 26% and 70%, respectively). Similarly, the levels of TLQP peptides were reduced in ALS fibroblasts (31% of controls) and in the NSC-34 treated with Sodium Arsenite (53% of decrease), however, the exogeneous TLQP-21 improved cell viability (SA-treated cells with TLQP-21, vs SA-treated cells only: about 83% vs. 75%). Hence, TLQP peptides, reduced upon oxidative stress, are suggested as blood biomarkers, while TLQP-21 exerts a neuroprotective activity. PMID- 29588253 TI - Evaluation of a specialized filter-paper matrix for transportation of extended bovine semen to screen for bovine herpesvirus-1 by real-time PCR. AB - The extended frozen semen (EFS) batches produced from infectious bovine rhinotracheitis (IBR) sero-positive cattle and buffalo bulls housed in various semen stations in India are transported to the testing laboratory in liquid nitrogen (LN2) for screening bovine herpesvirus-1 (BoHV-1). This procedure is laborious and poses LN2 related hazards. An alternative logistics for transportation of samples was investigated. Use of Flinders Technology Associates (FTA(r)) elute card was evaluated for transportation of extended bovine semen to screen BoHV-1 DNA by real-time PCR targeting gB gene and the method was compared with the OIE approved Chelex resin based method. A protocol for extraction of BoHV-1 DNA from FTA(r) card spotted with extended semen was optimized. The viral DNA was found to be stable on FTA(r) card for at least 28 days when the cards are stored at 4 degrees -37 degrees C. The analytical sensitivity for the assay was determined using variable dilutions of BoHV-1 spiked semen and positive plasmid harbouring gB gene (97bp) spotted onto FTA(r) card and it was found to be 100.8 TCID50/ml or 100 copies respectively in real-time PCR. The test could detect as low as 100.008 TCID50/ml or 1 copy of positive plasmid when more number of replicates (n = 6) of the same sample were tested. This sensitivity was found to be comparable to Chelex method and both the methods demonstrated a very strong correlation (r = 0.9774; 95% CI: 0.9620-0.9860) in terms of Ct value (p < 0.0001). The diagnostic sensitivity and specificity of the FTA method in comparison to the Chelex method was 83.08% (95% CI: 71.73%-91.24%) and 93.23% (95% CI: 89.38%-96.01%) respectively when 316 samples were screened by both the methods. The degree of agreement between these two tests was good (Kappa value: 0.738; 95% CI: 0.646-0.829). The method was found to be robust and highly repeatable in inter-assay and intra-assay precision testing. The result suggests that the FTA(r) card holds promise as an alternative system for transportation of EFS for downstream screening of BoHV-1 DNA. PMID- 29588254 TI - Efficiency of HIV-2 cultures from clinical isolates is enhanced after purification by anti-CD44 microbeads. AB - In-depth study of HIV often requires large stock of patients-derived viruses obtained through viral cultures. HIV cultures are currently limited by low recovery rates, especially when viral load is below 100,000 copies per mL. This is problematic for HIV-2 as most patients have spontaneously low to undetectable viremia. New approaches have been developed to enhance viral recovery rates but they are complex or costly to implement. We tested the impact of MUMACSTM VitalVirus Isolation Kit (Miltenyi), a HIV virions capture method using paramagnetic microbeads directed against CD44, a human glycoprotein present in HIV envelope. This method separates viruses from interfering proteins in 45 min, using a reduced sample volume (200 MUL versus 1000 MUL for classic culture assays). The impact of this purification method on virus recovery rate was assessed with 23 HIV-1 and 29 HIV-2 plasma samples with a wide range of viral loads, in comparison to a classic culture assay used routinely in our laboratory. For both HIV-1 and HIV-2, the culture identification delay was decreased using viral purification (<=7days in most cases). The recovery rate of cultures was improved for HIV-2 isolates (17/29 versus 8/29; p = 0.03) but not for HIV-1 (7/23 versus 5/23; p = 0.74). Notably, HIV-2 isolates with viral loads over 10,000 copies per mL were frequently recovered in culture (68% versus 32% without purification; p = 0.03). This marked improvement on HIV-2, but not on HIV-1, cultures is puzzling. CD44-microbeads may enable a close and prolonged contact between cells and viruses, and may thus overcome HIV-2 difficulties to infect target cells. PMID- 29588255 TI - Tumor-targeting CuS nanoparticles for multimodal imaging and guided photothermal therapy of lymph node metastasis. AB - : Precise diagnosis of lymph node metastasis to guide lymphadenectomy is highly important for gastric cancer therapy in clinics. Though surgical dissection of regional metastatic lymph nodes remains the only way for gastric cancer therapy, the extended dissection may cause unavoidable postoperative risk of complications. It is still lack of effective method enabling the accurate removal of metastatic gastric cancer cells in lymph nodes with minimum injuries to normal tissue. Herein, we report a new fluorescent copper sulfide (CuS) nanoparticle (RGD-CuS-Cy5.5) enabling both non-invasive multimodality imaging and targeting photothermal therapy (PTT) of metastatic gastric cancer cells in lymph nodes. We demonstrate that RGD-CuS-Cy5.5 can easily drain into sentinel lymph nodes (SLN) after injection into primary tumors, and selectively enter into metastatic gastric MNK45 tumor cells via alphavbeta3 integrin-mediated endocytosis. The resulting strong near-infrared (NIR) fluorescence and computed tomography (CT) contrast in metastatic SLN compared to normal SLN can precisely differentiate SLN metastasis of gastric cancers. Guided by the imaging, localized PTT with RGD-CuS Cy5.5 is conducted upon irradiation with an 808 nm laser, resulting in complete removal of metastatic gastric tumor cells in SLN without obvious toxicity. Moreover, RGD-CuS-Cy5.5 can also allow for the rapid and non-invasive self monitoring of PTT efficacy against metastatic SLNs in living mice. This study highlights the potential of using RGD-CuS-Cy5.5 for imaging-guided and targeting PTT of SLN metastasis in vivo, which may be applicable for the metastatic gastric cancer therapy in clinics. STATEMENT OF SIGNIFICANCE: RGD-CuS-Cy5.5 nanoparticles possess NIR fluorescence and CT signals for in vivo bimodality imaging of lymph node metastasis. Strong photothermal property under irradiation at 808 nm for efficient PTT. Easy drain into sentinel lymph nodes and selective enter metastatic gastric cancer cells via alphavbeta3 integrin-mediated endocytosis. Rapid and non-invasive monitoring of therapeutic efficacy against lymph node metastasis.

Material and Methods: Among a total of 131 primary or secondary infertile patients, 66 were shown an information video and 67 control patients received standard care between August 2014 and January 2016. The video included information on the procedure, personnel, and the room for the procedure; the video was shown on the morning of the procedure. Patients were randomized using the complete randomization technique through which patients were included in the study and control groups week by week, randomly. The Beck Anxiety Inventory scale was conducted to the patients one hour before the procedure. Results: There were no differences in demographic data. The history of previous gynecologic operations was higher in the control group. The Beck Anxiety score was significantly lower in the study group compared with the control group (6 vs 10). Conclusion: Our findings suggest that as an easy intervention to implement, a pre-procedural video education may be a beneficial tool for the management of HSG-related anxiety.

True diphallia with normal penile structures is extremely rare. Surgical management for patients with complete penile duplication without any penile or urethral pathology is challenging. CASE REPORT: A 4-year-old boy presented with diphallia. Initial physical examination revealed first physical examination revealed complete penile duplication, urine flow from both penises, meconium flow from right urethra, and anal atresia. Further evaluations showed double colon and rectum, double bladder, and large recto-vesical fistula. Two cavernous bodies and one spongious body were detected in each penile body. Surgical treatment plan consisted of right total penectomy and end-to-side urethra-urethrostomy. No postoperative complications and no voiding dysfunction were detected during the 18 months follow-up. CONCLUSION: Penile duplication is a rare anomaly, which presents differently in each patient. Because of this, the treatment should be individualized and end-to-side urethra-urethrostomy may be an alternative to removing posterior urethra. This approach eliminates the risk of damaging prostate gland and sphincter. PMID- 29588262 TI - Analyzing the etiology behind mortality associated with antepartum, intrapartum, and post-partum cases in a tertiary care teaching hospital of West Bengal AB - OBJECTIVE: The study was undertaken to understand the causes and circumstances of maternal deaths in West Bengal. MATERIAL AND METHODS: One hundred ten maternal deaths were reported during the period December 2010 through June 2012 in the Maternity Ward of Medical College and Hospitals, West Bengal. These deaths were reviewed using a facility-based Maternal Death Review protocol. The number and percentages were calculated and binary logistic regression analysis was performed. RESULTS: The majority of the deaths occurred in the 20-24 years' age group, those with Hindu religion, in the first and second gravida, and the postpartum period. One third of mothers had cesarean sections. The majority (78.2%) of deaths were among referred cases. Eclampsia was the leading cause of maternal death (29.1%). Approximately half of the deceased women sought care after 10 hours of developing complications. More than one-third of maternal deaths were registered with type 1 delays. CONCLUSION: Our study demonstrates that maternal deaths occurred among young women, referred cases, with cesarean sections and type 1 delays. We recommend that imparting basic skills and improving awareness to the community about the danger signs of pregnancy could be an effective measure to detect maternal complications at an earlier stage. PMID- 29588263 TI - Injury of the Prefrontocaudate Tract in a Patient with a Bilateral Caudate Infarct PMID- 29588264 TI - Prognostic effect of isolated paraaortic nodal spread in endometrial cancer AB - Objective: To evaluate the prognostic effect of isolated paraaortic lymph node metastasis in endometrial cancer (EC). Material and Methods: This retrospective study included patients with FIGO 2009 stage IIIC2 disease due to isolated paraaortic lymph node metastasis (LNM). Patients with sarcomatous histology, synchronous gynecologic cancers and patients with concurrent pelvic lymph node metastases or patients that have intraabdominal tumor spread were excluded. Kaplan-Meier method was used for calculation of progression free survival (PFS) and overall survival. Results: One thousand six hundred and fourteen patients were operated for EC during study period. Nine hundred and sixty-one patients underwent lymph node dissection and 25 (2.6%) were found to have isolated LNM in paraaortic region and these constituted the study cohort. Twenty (80%) patients had endometrioid EC. Median number of retrieved lymph nodes from pelvic region and paraaortic region was 21.5 (range: 5-41) and 34.5 (range: 1-65), respectively. Median number of metastatic paraaortic nodes was 1 (range: 1-32). The median follow-up time was 15 months (range 5-94). Seven (28%) patients recurred after a median of 20 months (range, 3-99) from initial surgery. Three patients recurred only in pelvis, one patient had upper abdominal spread and 3 had isolated extraabdominal recurrence. Involvement of uterine serosa, positive peritoneal cytology and presence of adnexal metastasis were significantly associated with diminished PFS (p<0.05). Conclusion: The presence of serosal involvement or adnexal involvement is as important as gross peritoneal spread and is related with poor survival in patients with isolated paraaortic nodal spread in EC. Chemotherapy should be the mainstay of treatment in this patient cohort which may eradicate systemic tumor spread. PMID- 29588265 TI - Double Pyramidal Lobe of the Thyroid Gland.

AB - BACKGROUND: Physical inactivity is the fourth leading cause of death worldwide, costing approximately US $67.5 billion per year to health care systems. To curb the physical inactivity pandemic, it is time to move beyond traditional approaches and engage citizens by repurposing sedentary behavior (SB)-enabling ubiquitous tools (eg, smartphones). OBJECTIVE: The primary objective of the Saskatchewan, let's move and map our activity (SMART) Study was to develop a mobile and citizen science methodological platform for active living surveillance, knowledge translation, and policy interventions. This methodology paper enumerates the SMART Study platform's conceptualization, design, implementation, data collection procedures, analytical strategies, and potential for informing policy interventions. METHODS: This longitudinal investigation was designed to engage participants (ie, citizen scientists) in Regina and Saskatoon, Saskatchewan, Canada, in four different seasons across 3 years. In spring 2017, pilot data collection was conducted, where 317 adult citizen scientists (>=18 years) were recruited in person and online. Citizen scientists used a custom built smartphone app, Ethica (Ethica Data Services Inc), for 8 consecutive days to provide a complex series of objective and subjective data. Citizen scientists answered a succession of validated surveys that were assigned different smartphone triggering mechanisms (eg, user-triggered and schedule-triggered). The validated surveys captured physical activity (PA), SB, motivation, perception of outdoor and indoor environment, and eudaimonic well-being. Ecological momentary assessments were employed on each day to capture not only PA but also physical and social contexts along with barriers and facilitators of PA, as relayed by citizen scientists using geo-coded pictures and audio files. To obtain a comprehensive objective picture of participant location, motion, and compliance, 6 types of sensor-based (eg, global positioning system and accelerometer) data were surveilled for 8 days. Initial descriptive analyses were conducted using geo coded photographs and audio files. RESULTS: Pictures and audio files (ie, community voices) showed that the barriers and facilitators of active living included intrinsic or extrinsic motivations, social contexts, and outdoor or indoor environment, with pets and favorable urban design featuring as the predominant facilitators, and work-related screen time proving to be the primary barrier. CONCLUSIONS: The preliminary pilot results show the flexibility of the SMART Study surveillance platform in identifying and addressing limitations based on empirical evidence. The results also show the successful implementation of a platform that engages participants to catalyze policy interventions. Although SMART Study is currently geared toward surveillance, using the same platform, active living interventions could be remotely implemented. SMART Study is the first mobile, citizen science surveillance platform utilizing a rigorous, longitudinal, and mixed-methods investigation to temporally capture behavioral data for knowledge translation and policy interventions. PMID- 29588268 TI - Satisfying Product Features of a Fall Prevention Smartphone App and Potential Users' Willingness to Pay: Web-Based Survey Among Older Adults. AB - BACKGROUND: Prohibiting falls and fall-related injuries is a major challenge for health care systems worldwide, as a substantial proportion of falls occur in older adults who are previously known to be either frail or at high risk for falls. Hence, preventive measures are needed to educate and minimize the risk for falls rather than just minimize older adults' fall risk. Health apps have the potential to address this problem, as they enable users to self-assess their individual fall risk. OBJECTIVE: The objective of this study was to identify product features of a fall prevention smartphone app, which increase or decrease users' satisfaction. In addition, willingness to pay (WTP) was assessed to explore how much revenue such an app could generate. METHODS: A total of 96 participants completed an open self-selected Web-based survey. Participants answered various questions regarding health status, subjective and objective fall risk, and technical readiness. Seventeen predefined product features of a fall prevention smartphone app were evaluated twice: first, according to a functional (product feature is implemented in the app), and subsequently by a dysfunctional (product feature is not implemented in the app) question. On the basis of the combination of answers from these 2 questions, the product feature was assigned to a certain category (must-be, attractive, one-dimensional, indifferent, or questionable product feature). This method is widely used in user-oriented product development and captures users' expectations of a product and how their satisfaction is influenced by the availability of individual product features. RESULTS: Five product features were identified to increase users' acceptance, including (1) a checklist of typical tripping hazards, (2) an emergency guideline in case of a fall, (3) description of exercises and integrated workout plans that decrease the risk of falling, (4) inclusion of a continuous workout program, and (5) cost coverage by health insurer. Participants' WTP was assessed after all 17 product features were rated and revealed a median monthly payment WTP rate of ?5.00 (interquartile range 10.00). CONCLUSIONS: The results show various motivating product features that should be incorporated into a fall prevention smartphone app. Results reveal aspects that fall prevention and intervention designers should keep in mind to encourage individuals to start joining their program and facilitate long-term user engagement, resulting in a greater interest in fall risk prevention. PMID- 29588269 TI - Developing a Shared Patient-Centered, Web-Based Medication Platform for Type 2 Diabetes Patients and Their Health Care Providers: Qualitative Study on User Requirements. AB - BACKGROUND: Information technology tools such as shared patient-centered, Web based medication platforms hold promise to support safe medication use by strengthening patient participation, enhancing patients' knowledge, helping patients to improve self-management of their medications, and improving communication on medications among patients and health care professionals (HCPs). However, the uptake of such platforms remains a challenge also due to inadequate user involvement in the development process. Employing a user-centered design (UCD) approach is therefore critical to ensure that user' adoption is optimal. OBJECTIVE: The purpose of this study was to identify what patients with type 2 diabetes mellitus (T2DM) and their HCPs regard necessary requirements in terms of functionalities and usability of a shared patient-centered, Web-based medication platform for patients with T2DM. METHODS: This qualitative study included focus groups with purposeful samples of patients with T2DM (n=25), general practitioners (n=13), and health care assistants (n=10) recruited from regional health care settings in southwestern Germany. In total, 8 semistructured focus groups were conducted. Sessions were audio- and video-recorded, transcribed verbatim, and subjected to a computer-aided qualitative content analysis. RESULTS: Appropriate security and access methods, supported data entry, printing, and sending information electronically, and tracking medication history were perceived as the essential functionalities. Although patients wanted automatic interaction checks and safety alerts, HCPs on the contrary were concerned that unspecific alerts confuse patients and lead to nonadherence. Furthermore, HCPs were opposed to patients' ability to withhold or restrict access to information in the platform. To optimize usability, there was consensus among participants to display information in a structured, chronological format, to provide information in lay language, to use visual aids and customize information content, and align the platform to users' workflow. CONCLUSIONS: By employing a UCD, this study provides insight into the desired functionalities and usability of patients and HCPs regarding a shared patient-centered, Web-based medication platform, thus increasing the likelihood to achieve a functional and useful system. Substantial and ongoing engagement by all intended user groups is necessary to reconcile differences in requirements of patients and HCPs, especially regarding medication safety alerts and access control. Moreover, effective training of patients and HCPs on medication self-management (support) and optimal use of the tool will be a prerequisite to unfold the platform's full potential. PMID- 29588270 TI - Impacts of Urban Agriculture on the Determinants of Health: Scoping Review Protocol. AB - BACKGROUND: Since the 1990s, urban agriculture (UA) has contributed to improving food security in low- and middle- income countries. Now, it is implemented as a multifunctional intervention that can influence various determinants of health (eg, food security, social relationships). Studies of interest stem from several research disciplines, use a wide range of methods, and show results that are sometimes inconsistent. Current studies have not summarized the overall effects of UA on health and its determinants. OBJECTIVE: The objective of this protocol is to develop a research strategy for a scoping review that characterizes studies of beneficial and adverse impacts of UA on health and its determinants in a wide range of disciplines. METHODS: Initially, with the help of a library specialist, a list of publications will be obtained through a systematic search of seven electronic bibliographic databases: PubMed, Embase, MEDLINE (Embase), CINAHL Plus with full text, Academic Search Premier (EBSCO host), CAB Abstract (Ovid), and Web of Science. Secondly, a three-step screening by two independent reviewers will lead to a list of relevant publications that meet eligibility and inclusion criteria. Finally, data on the bibliography, type of participants, type of study, results of study, and countries will be extracted from included articles and analyzed to be presented in a peer-reviewed article. RESULTS: The findings are expected to identify research gaps that will inform needs for UA research in specific fields (eg, mental health), among certain population groups (eg, adults) or within different economic contexts (eg, low-, middle-, or high-income countries). Furthermore, the findings are expected to identify knowledge gaps and direct future research needs. CONCLUSIONS: This is an original study that seeks to integrate beneficial and adverse effects of UA on health at different level of influence (individuals, households, and community) in order to facilitate a better understanding of UA impacts. This protocol is a first of its kind and is expected to lead to a characterization of UA impacts based on sociodemographic profiles of participants and income levels of the studied countries. This will be relevant for policy makers and UA practitioners. PMID- 29588271 TI - Development of an Exergame to Deliver a Sustained Dose of High-Intensity Training: Formative Pilot Randomized Trial. AB - BACKGROUND: Sport science can play a critical role in reducing health inequalities. The inverse relationship between life expectancy, cardiorespiratory fitness, and socioeconomic status could be addressed by performing high-intensity training (HIT), delivered in a class salient and accessible approach. Commercially available exergames have shown encouraging compliance rates but are primarily designed for entertainment purposes rather than focusing on health related outcomes. A serious game tailored toward delivering an exercise stimulus, while reducing the aversive protocols associated with HIT, could be beneficial to engage and improve health outcomes in socially deprived males. OBJECTIVE: The aims of this study were to develop an exergame capable of delivering HIT and evaluate the effect on selected health outcomes in men recruited in regions of socioeconomic deprivation. METHODS: We conducted an exploratory trial in our target population, and participants were allocated to intervention (n=14) or control groups (n=10) by third-party minimization. The intervention was a 6-week training program consisting of three sessions of exergaming per week. The sessions involved a structured warm-up, then brief intermittent repetitions in the form of boxing rounds (10 s, 20 s, and 30 s) against their peers with a work/rest ratio of 0.25. RESULTS: Retention to the intervention was 87.5% (21/24). Over the duration of the intervention, session attendance was 67.5% (170/252); repetition mean and peak heart rates (% of maximal) and session ratings of perceived exertion (AU, arbitrary units) were 86.3 (5.4%), 89.9 (6.1%), and 7.5 (2.2 AU), respectively. The effect of the intervention, when compared with the control, was a likely small beneficial improvement in predicted maximum oxygen consumption (VO2 max, 3.0; 90% confidence limits +/-2.6%). Effects on body mass, waist circumference, and blood pressure were either trivial or unclear. CONCLUSIONS: Over the 6-week intervention, the exergame delivered a consistent and sustained dose of HIT, with some beneficial effects on aerobic fitness in the target population.

PMID- 29588272 TI - Integration of a Technology-Based Mental Health Screening Program Into Routine Practices of Primary Health Care Services in Peru (The Allillanchu Project): Development and Implementation. AB - BACKGROUND: Despite their high prevalence and significant burden, mental disorders such as depression remain largely underdiagnosed and undertreated. OBJECTIVE: The aim of the Allillanchu Project was to design, develop, and test an intervention to promote early detection, opportune referral, and access to treatment of patients with mental disorders attending public primary health care (PHC) services in Lima, Peru. METHODS: The project had a multiphase design: formative study, development of intervention components, and implementation. The intervention combined three strategies: training of PHC providers (PHCPs), task shifting the detection and referral of mental disorders, and a mobile health (mHealth) component comprising a screening app followed by motivational and reminder short message service (SMS) to identify at-risk patients. The intervention was implemented by 22 PHCPs from five health centers, working in antenatal care, tuberculosis, chronic diseases, and HIV or AIDS services. RESULTS: Over a period of 9 weeks, from September 2015 to November 2015, 733 patients were screened by the 22 PHCPs during routine consultations, and 762 screening were completed in total. The chronic diseases (49.9%, 380/762) and antenatal care services (36.7%, 380/762) had the higher number of screenings. Time constraints and workload were the main barriers to implementing the screening, whereas the use of technology, training, and supervision of the PHCPs by the research team were identified as facilitators. Of the 733 patients, 21.7% (159/733) screened positively and were advised to seek specialized care. Out of the 159 patients with a positive screening result, 127 had a follow-up interview, 72.4% (92/127) reported seeking specialized care, and 55.1% (70/127) stated seeing a specialist. Both patients and PHCPs recognized the utility of the screening and identified some key challenges to its wider implementation. CONCLUSIONS: The use of a screening app supported by training and supervision is feasible and uncovers a high prevalence of unidentified psychological symptoms in primary care. To increase its sustainability and utility, this procedure can be incorporated into the routine practices of existing health care services, following tailoring to the resources and features of each service. The early detection of psychological symptoms by a PHCP within a regular consultation, followed by adequate advice and support, can lead to a significant percentage of patients accessing specialized care and reducing the treatment gap of mental disorders. PMID- 29588274 TI - Digital Transformation and Disruption of the Health Care Sector: Internet-Based Observational Study. AB - BACKGROUND: Digital innovation, introduced across many industries, is a strong force of transformation. Some industries have seen faster transformation, whereas the health care sector only recently came into focus. A context where digital corporations move into health care, payers strive to keep rising costs at bay, and longer-living patients desire continuously improved quality of care points to a digital and value-based transformation with drastic implications for the health care sector. OBJECTIVE: We tried to operationalize the discussion within the health care sector around digital and disruptive innovation to identify what type of technological enablers, business models, and value networks seem to be emerging from different groups of innovators with respect to their digital transformational efforts. METHODS: From the Forbes 2000 and CBinsights databases, we identified 100 leading technology, life science, and start-up companies active in the health care sector. Further analysis identified projects from these companies within a digital context that were subsequently evaluated using the following criteria: delivery of patient value, presence of a comprehensive and distinctive underlying business model, solutions provided, and customer needs addressed. RESULTS: Our methodological approach recorded more than 400 projects and collaborations. We identified patterns that show established corporations rely more on incremental innovation that supports their current business models, while start-ups engage their flexibility to explore new market segments with notable transformations of established business models. Thereby, start-ups offer higher promises of disruptive innovation. Additionally, start-ups offer more diversified value propositions addressing broader areas of the health care sector. CONCLUSIONS: Digital transformation is an opportunity to accelerate health care performance by lowering cost and improving quality of care. At an economic scale, business models can be strengthened and disruptive innovation models enabled. Corporations should look for collaborations with start-up companies to keep investment costs at bay and off the balance sheet. At the same time, the regulatory knowledge of established corporations might help start-ups to kick off digital disruption in the health care sector. PMID- 29588275 TI - Differential ubiquitination in NETs regulates macrophage responses in systemic lupus erythematosus. AB - OBJECTIVES: To assess if ubiquitinated proteins potentially present in neutrophil extracellular traps (NETs) can modify cellular responses and induce inflammatory mechanisms in patients with systemic lupus erythematosus (SLE) and healthy subjects. MATERIALS AND METHODS: We studied 74 subjects with SLE and 77 healthy controls. Neutrophils and low-density granulocytes were isolated, and NETs were induced. Ubiquitin content was quantified in NETs by western blot analysis, ELISA and immunofluorescence microscopy, while ubiquitination of NET proteins was assessed by immunoprecipitation. Monocyte-derived macrophages from SLE and controls were isolated and stimulated with NETs or ubiquitin. Calcium flux and cytokine synthesis were measured following these stimuli. RESULTS: NETs contain ubiquitinated proteins, with a lower expression of polyubiquitinated proteins in subjects with SLE than in controls. Myeloperoxidase (MPO) is present in ubiquitinated form in NETs. Patients with SLE develop antiubiquitinated MPO antibodies, and titres positively correlate with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score (P<0.01), and negatively correlate with complement components (P<0.01). Stimulation of monocyte-derived macrophages with NETs or with ubiquitin led to enhanced calcium flux. In addition, stimulation with NETs led to enhanced cytokine (tumour necrosis factor-alpha and interleukin 10) production in macrophages from patients with SLE when compared with controls, which was hampered by inhibition of NET internalisation by macrophages. CONCLUSION: This is the first study to find ubiquitinated proteins in NETs, and evidence for adaptive immune responses directed towards ubiquitinated NET proteins in SLE. The distinct differences in ubiquitin species profile in NETs compared with healthy controls may contribute to dampened anti-inflammatory responses observed in SLE. These results also support a role for extracellular ubiquitin in inflammation in SLE. PMID- 29588273 TI - Monitoring Energy Balance in Breast Cancer Survivors Using a Mobile App: Reliability Study. AB - BACKGROUND: The majority of breast cancer survivors do not meet recommendations in terms of diet and physical activity. To address this problem, we developed a mobile health (mHealth) app for assessing and monitoring healthy lifestyles in breast cancer survivors, called the Energy Balance on Cancer (BENECA) mHealth system. The BENECA mHealth system is a novel and interactive mHealth app, which allows breast cancer survivors to engage themselves in their energy balance monitoring. BENECA was designed to facilitate adherence to healthy lifestyles in an easy and intuitive way. OBJECTIVE: The objective of the study was to assess the concurrent validity and test-retest reliability between the BENECA mHealth system and the gold standard assessment methods for diet and physical activity. METHODS: A reliability study was conducted with 20 breast cancer survivors. In the study, tri-axial accelerometers (ActiGraphGT3X+) were used as gold standard for 8 consecutive days, in addition to 2, 24-hour dietary recalls, 4 dietary records, and sociodemographic questionnaires. Two-way random effect intraclass correlation coefficients, a linear regression-analysis, and a Passing-Bablok regression were calculated. RESULTS: The reliability estimates were very high for all variables (alpha>=.90). The lowest reliability was found in fruit and vegetable intakes (alpha=.94). The reliability between the accelerometer and the dietary assessment instruments against the BENECA system was very high (intraclass correlation coefficient=.90). We found a mean match rate of 93.51% between instruments and a mean phantom rate of 3.35%. The Passing-Bablok regression analysis did not show considerable bias in fat percentage, portions of fruits and vegetables, or minutes of moderate to vigorous physical activity. CONCLUSIONS: The BENECA mHealth app could be a new tool to measure energy balance in breast cancer survivors in a reliable and simple way. Our results support the use of this technology to not only to encourage changes in breast cancer survivors' lifestyles, but also to remotely monitor energy balance.

PMID- 29588276 TI - Defining refractory rheumatoid arthritis. AB - While biologic disease-modifying antirheumatic drugs (bDMARDs) have transformed outcomes of people with rheumatoid arthritis (RA), a proportion of patients are refractory to multiple bDMARDs. Definitions of refractory RA thus far have been arbitrary, and outcome data and impact of such cohorts remain limited. Extrapolation from randomised controlled trial and some real-life data suggest approximately 20% progress onto a third bDMARD with a more modest proportion failing additional bDMARDs. This viewpoint discusses an opinion of refractory RA disease and proposes key principles to accurately identify refractory cohorts. These include demonstrating presence of persistent inflammation despite multiple therapies and acknowledging development of antidrug antibody. Potential basis of refractory disease is summarised, and suggestions for an initial approach in the future evaluation of refractory disease are offered. Specific investigation of refractory RA disease is necessary to inform the clinical need and provide a basis for robust investigation of underlying mechanisms.

PMID- 29588277 TI - Tolerogenic properties of the Fc portion of IgG and its relevance to the treatment and management of hemophilia AB - Hemophilia, or inherited genetic deficiencies in coagulation factors, results in uncontrolled bleeding requiring replacement therapy with recombinant proteins given preventively or on demand. However, a major problem with these approaches is the potential for development of immune responses to the administered proteins due to the underlying genetic deficiency of the factor(s) throughout life. As such, there is great interest in developing strategies that avoid immunogenicity and induce immune tolerance. Recently, recombinant factor VIII (rFVIII) and rFIX fused to the crystallizable fragment (Fc) domain of immunoglobulin G (IgG) have been developed as therapeutic agents for hemophilia A and B, respectively. Although it is well known that the possession of an Fc domain confers IgG's longer-lasting circulating half-life, it is not generally appreciated that the Fc domain also confers immunoregulatory properties that are associated with the induction of tolerance. Here, we review some of the latest advances in our understanding of the tolerogenic abilities of IgG Fc and the impact of Fc-fusion proteins of rFVIII on the treatment of hemophilia. PMID- 29588278 TI - A single-cell hematopoietic landscape resolves 8 lineage trajectories and defects in Kit mutant mice. AB - Hematopoietic stem and progenitor cells (HSPCs) maintain the adult blood system, and their dysregulation causes a multitude of diseases. However, the differentiation journeys toward specific hematopoietic lineages remain ill defined, and system-wide disease interpretation remains challenging. Here, we have profiled 44 802 mouse bone marrow HSPCs using single-cell RNA sequencing to provide a comprehensive transcriptional landscape with entry points to 8 different blood lineages (lymphoid, megakaryocyte, erythroid, neutrophil, monocyte, eosinophil, mast cell, and basophil progenitors). We identified a common basophil/mast cell bone marrow progenitor and characterized its molecular profile at the single-cell level. Transcriptional profiling of 13 815 HSPCs from the c-Kit mutant (W41/W41) mouse model revealed the absence of a distinct mast cell lineage entry point, together with global shifts in cell type abundance. Proliferative defects were accompanied by reduced Myc expression. Potential compensatory processes included upregulation of the integrated stress response pathway and downregulation of proapoptotic gene expression in erythroid progenitors, thus providing a template of how large-scale single-cell transcriptomic studies can bridge between molecular phenotypes and quantitative population changes. PMID- 29588280 TI - Clinical presentation of Lyme disease in the higher-risk region of Quebec: a retrospective descriptive study. AB - BACKGROUND: Lyme disease is emerging in Canada. This study aimed to describe the use of serologic testing for the disease in the La Pommeraie health region in southern Quebec between 2012 and 2015 and to describe the clinical presentation of laboratory-confirmed cases. METHODS: The medical charts of all patients investigated for Lyme disease at the Brome-Missisquoi-Perkins Hospital's laboratory between 2012 and 2015 were reviewed for results of serologic testing. Laboratory diagnosis was based on 2-tiered testing: cases had to have positive results of both the enzyme immunoassay and the Western blot test (IgM or IgG). We collected data on clinical presentation for patients assessed at the hospital or at the La Pommeraie Family Medicine Unit. RESULTS: Over the study period, 720 patients were investigated for Lyme disease. There was a more than fivefold increase in requests for serologic testing from 2012 (53) to 2015 (273). The number of confirmed cases increased from 2012 (3) to 2013 (19) and remained stable thereafter (19 in 2014, 18 in 2015). Fifty patients were positive for IgM with or without IgG positivity, and 9 patients were IgG-positive only. Chart reviews were completed for 278 of the 720 patients, including 38 of the 59 laboratory-confirmed cases. Among the 29 IgM-positive patients, the most common symptoms were fever (17 patients [59%]), fatigue (14 [48%]), myalgia (12 [41%]) and headaches (10 [34%]). Twenty-three (79%) had some cutaneous manifestation, including specifically erythema migrans (14 [48%]). A tick bite was reported by 11 patients (38%). Of the 44 patients in the entire study population who presented with erythema migrans, 15 (34%) had confirmed Lyme disease. INTERPRETATION: Requests for serologic testing for Lyme disease increased in the La Pommeraie health region over recent years. Cutaneous manifestations, fever and myalgia were the most common symptoms of IgM-positive cases. Most patients did not report a tick bite. PMID- 29588281 TI - When a transfusion in an emergency service is not really urgent: hyperhaemolysis syndrome in a child with sickle cell disease. AB - A 13-month-old boy with sickle cell disease (SCD) from Equatorial Guinea, who had recently arrived in Spain, presented with fever. He had suffered from malaria and had received a blood transfusion. Following physical examination and complementary tests, intravenous antibiotics and a red blood cell (RBC) transfusion were administered. Soon after a second transfusion 5 days later, the haemoglobin level fell below pretransfusion levels, together with reticulocytopenia, and haematuria-the so-called hyperhaemolysis syndrome requiring intensive care and treatment with intravenous immunoglobulins and corticosteroids, with resolution of the complication. We want to emphasise the importance of suspecting this rare, though severe complication that can appear after any RBC transfusion especially in patients with SCD, as the clinical syndrome can simulate other more common complications of these patients and a further transfusion is contraindicated. There is no standardised treatment, but intravenous immunoglobulin and corticosteroids are usually effective.

AB - Mitochondria are fundamental for cellular metabolism as they are both a source and a target of nutrient intermediates originating from converging metabolic pathways, and their role in the regulation of systemic metabolism is increasingly recognized. Thus, maintenance of mitochondrial homeostasis is indispensable for a functional energy metabolism of the whole organism. Here, we report that loss of the mitochondrial matrix protease CLPP results in a lean phenotype with improved glucose homeostasis. Whole-body CLPP-deficient mice are protected from diet induced obesity and insulin resistance, which was not present in mouse models with either liver- or muscle-specific depletion of CLPP However, CLPP ablation also leads to a decline in brown adipocytes function leaving mice unable to cope with a cold-induced stress due to non-functional adaptive thermogenesis. These results demonstrate a critical role for CLPP in different metabolic stress conditions such as high-fat diet feeding and cold exposure providing tools to understand pathologies with deregulated Clpp expression and novel insights into therapeutic approaches against metabolic dysfunctions linked to mitochondrial diseases. PMID- 29588286 TI - Circulating Sphingolipids, Insulin, HOMA-IR, and HOMA-B: The Strong Heart Family Study. AB - Experimental studies suggest ceramides may play a role in insulin resistance. However, the relationships of circulating ceramides and related sphingolipids with plasma insulin have been underexplored in humans. We measured 15 ceramide and sphingomyelin species in fasting baseline samples from the Strong Heart Family Study (SHFS), a prospective cohort of American Indians. We examined sphingolipid associations with both baseline and follow-up measures of plasma insulin, HOMA of insulin resistance (HOMA-IR), and HOMA of beta-cell function (HOMA-B) after adjustment for risk factors. Among the 2,086 participants without diabetes, higher levels of plasma ceramides carrying the fatty acids 16:0 (16 carbons, 0 double bond), 18:0, 20:0, or 22:0 were associated with higher plasma insulin and higher HOMA-IR at baseline and at follow-up an average of 5.4 years later. For example, a twofold higher baseline concentration of ceramide 16:0 was associated with 14% higher baseline insulin (P < 0.0001). Associations between sphingomyelin species carrying 18:0, 20:0, 22:0, or 24:0 and insulin were modified by BMI (P < 0.003): higher levels were associated with lower fasting insulin, HOMA-IR, and HOMA-B among those with normal BMI. Our study suggests lowering circulating ceramides might be a target in prediabetes and targeting circulating sphingomyelins should take into account BMI.

PMID- 29588287 TI - Fanconi Anemia FANCM/FNCM-1 and FANCD2/FCD-2 Are Required for Maintaining Histone Methylation Levels and Interact with the Histone Demethylase LSD1/SPR-5 in Caenorhabditis elegans. AB - The histone demethylase LSD1 was originally discovered by removing methyl groups from di- and monomethylated histone H3 lysine 4 (H3K4me2/1). Several studies suggest that LSD1 plays roles in meiosis as well as in the epigenetic regulation of fertility given that, in its absence, there is evidence of a progressive accumulation of H3K4me2 and increased sterility through generations. In addition to the progressive sterility phenotype observed in the mutants, growing evidence for the importance of histone methylation in the regulation of DNA damage repair has attracted more attention to the field in recent years. However, we are still far from understanding the mechanisms by which histone methylation is involved in DNA damage repair, and only a few studies have focused on the roles of histone demethylases in germline maintenance. Here, we show that the histone demethylase LSD1/CeSPR-5 interacts with the Fanconi anemia (FA) protein FANCM/CeFNCM-1 using biochemical, cytological, and genetic analyses. LSD1/CeSPR-5 is required for replication stress-induced S phase-checkpoint activation, and its absence suppresses the embryonic lethality and larval arrest observed in fncm-1 mutants. FANCM/CeFNCM-1 relocalizes upon hydroxyurea exposure and colocalizes with FANCD2/CeFCD-2 and LSD1/CeSPR-5, suggesting coordination between this histone demethylase and FA components to resolve replication stress. Surprisingly, the FA pathway is required for H3K4me2 maintenance, regardless of the presence of replication stress. Our study reveals a connection between FA and epigenetic maintenance and therefore provides new mechanistic insight into the regulation of histone methylation in DNA repair.

AB - High-throughput sequencing methods that multiplex a large number of individuals have provided a cost-effective approach for discovering genome-wide genetic variation in large populations. These sequencing methods are increasingly being utilized in population genetic studies across a diverse range of species. Two side-effects of these methods, however, are (1) sequencing errors and (2) heterozygous genotypes called as homozygous due to only one allele at a particular locus being sequenced, which occurs when the sequencing depth is insufficient. Both of these errors have a profound effect on the estimation of linkage disequilibrium (LD) and, if not taken into account, lead to inaccurate estimates. We developed a new likelihood method, GUS-LD, to estimate pairwise linkage disequilibrium using low coverage sequencing data that accounts for undercalled heterozygous genotypes and sequencing errors. Our findings show that accurate estimates were obtained using GUS-LD, whereas underestimation of LD results if no adjustment is made for the errors.

PMID- 29588293 TI - Associations Between Changes in Depressive Symptoms and Social Support and Diabetes Management Among Low-Income, Predominantly Hispanic Patients in Patient Centered Care. AB - OBJECTIVE: This study examined whether changes in depressive symptoms and social support prospectively predicted diabetes management among Hispanic patients with probable depression in patient-centered medical homes at safety-net clinics in East Los Angeles, CA. RESEARCH DESIGN AND METHODS: Data were collected from 251 patients enrolled in a randomized clinical trial testing the effectiveness of a self-management intervention assisted by a promotora (Hispanic community health worker). Cross-lagged analyses examined associations between changes in depression symptoms and social support between baseline and 6-month follow-up and self-efficacy and adherence to diabetes management at the 6- and 12-month follow ups. RESULTS: Changes in depressive symptoms predicted self-efficacy and level of adherence at the 6- and 12-month follow-ups. Changes in total social support and emotional social support were correlated only with self-efficacy regarding diabetes management at 6-month follow-up. CONCLUSIONS: Decline in depressive symptoms is a reliable predictor of improvement in self-efficacy and adherence to diabetes management. Further studies are recommended to study psychosocial mechanisms related to social relationships other than social support that affect diabetes management. PMID- 29588294 TI - Aggressive pituitary tumours and carcinomas: two sides of the same coin? AB - The European Society of Endocrinology (ESE) survey reported on the largest cohort of 125 aggressive pituitary tumours (APT) and 40 pituitary carcinomas (PC). Whilst the survey focused on treatment effectiveness, all pathological data were not explored in detail. Here, we comment on some interesting pathological findings, notably the difference between APT and PC. PMID- 29588295 TI - Early-onset neonatal infections in Australia and New Zealand, 2002-2012. AB - BACKGROUND: The epidemiology of early-onset neonatal sepsis (EONS) varies over time, and requires regular surveillance. OBJECTIVE: To analyse data on EONS in Australia and New Zealand. METHODS: Retrospective analysis of data collected longitudinally from multiple neonatal units from 2002 to 2012. RESULTS: Of 386 423 live births, 454 infants had EONS. The incidence rate of EONS was 1.20 per 1000 live births in 2002 and 0.83 in 2012, decreasing by 4% per year (95% CI 1% to 7%, p=0.007). Group B streptococcus (GBS) (37%) and Escherichia coli (25%) were the most prevalent organisms. The early-onset GBS (EOGBS) incidence rate was 0.43/1000 live births, with no evidence of change over time (p=0.3). Of EOGBS infected babies, 62% were born at term compared with 8% with early-onset E. coli sepsis, p<0.0001. The mortality of E. coli early-onset sepsis (EOS) (25%) was higher than GBS (11%), but this difference in mortality was no longer significant after adjusting for gestation and birth weight. Mortality from EOS fell significantly over the study period (17% per year, 95% CI 10 to 24, p<0.0001). CONCLUSIONS: GBS was the most common cause of early sepsis, but the incidence was lower than prior to the introduction of intrapartum antibiotic prophylaxis, and remained steady over time. The mortality of early-onset E. coli sepsis was significantly higher than GBS sepsis, but this may have been because almost all babies with E. coli were born preterm, rather than a difference in virulence.

AB - Infections of the central nervous system due to Candida albicans are uncommon and are usually only observed in special circumstances, such as following neurosurgery or penetrating head trauma, in immunosuppressed patients, premature infants or in patients with ventriculoperitoneal shunts. The author reports a case of an immunocompetent man who presented with a thoracic intraspinal abscess due to C. albicans Despite surgical drainage and 6 weeks of high-dose fluconazole therapy, the abscess extended and recurred in the cervical spine, requiring a second operation to arrest the infection. PMID- 29588298 TI - Severe immune thrombocytopaenia in a patient taking benznidazole for chronic Chagas disease. AB - Chagas disease is a parasitic disease that mostly affects Latin American countries, but it has currently become a worldwide epidemic due to migration. Both drugs marketed for its treatment (benznidazole and nifurtimox) are associated with a high rate of adverse reactions. Benznidazole is preferred initially because of its more favourable toxicity profile and perceived greater efficacy. Hypersensitivity dermatological reactions, gastrointestinal and neurological disturbances represent the most common drug-related adverse events. General symptoms such as fever, arthralgia, myalgia or bone marrow depression (leucopaenia) are seen less frequently. We describe the case of a 33-year-old woman with chronic Chagas disease who presented with acute gingival bleeding and severe thrombocytopaenia, probably related to benznidazole treatment. Temporal association with drug initiation and recovery after treatment withdrawal were demonstrated. Clinicians should be aware of the possible association between immune thrombocytopaenia and benznidazole, even though the pathogenesis remains unclear at present. PMID- 29588299 TI - Streptococcus pyogenes primary peritonitis. AB - Streptococcus pyogenes, a Gram-positive bacterium, is a rare cause of primary peritonitis. Diagnosed on imaging and with positive growth in blood cultures, a case of primary peritonitis caused by S. pyogenes is discussed here, with a brief literature review, and used to discuss several key principles of antibiotic use, including selection of antibiotic, investigations and non-pharmacological management of infection. PMID- 29588300 TI - Episodes of extreme lower leg pain caused by intraosseous varicose veins. AB - We present a case of a 67-year-old man with episodes of extreme pain of the right lower extremity that prevented him from walking and sleeping. The patient had a history of varices in both legs. Physical examination showed a pretibial varix of the right leg inferiorly from a painful spot. X-ray of the right lower leg showed a cortex disruption at this spot. MRIs confirmed the disruption of the cortex of the right tibia and demonstrated an intraosseous vessel. The diagnosis intraosseous varices was made and the vein was surgically resected. Follow-up took place after 3 years and the patient was free from any symptoms related to the intraosseous varicose vein. The pathophysiology causing the pain symptoms is hard to understand, partly due to the limited cases presented with such anomalies. We demonstrate our case in the hope to generate more knowledge about this disorder. PMID- 29588296 TI - Estimating neonatal length of stay for babies born very preterm. AB - OBJECTIVE: To predict length of stay in neonatal care for all admissions of very preterm singleton babies. SETTING: All neonatal units in England. PATIENTS: Singleton babies born at 24-31 weeks gestational age from 2011 to 2014. Data were extracted from the National Neonatal Research Database. METHODS: Competing risks methods were used to investigate the competing outcomes of death in neonatal care or discharge from the neonatal unit. The occurrence of one event prevents the other from occurring. This approach can be used to estimate the percentage of babies alive, or who have been discharged, over time. RESULTS: A total of 20 571 very preterm babies were included. In the competing risks model, gestational age was adjusted for as a time-varying covariate, allowing the difference between weeks of gestational age to vary over time. The predicted percentage of death or discharge from the neonatal unit were estimated and presented graphically by week of gestational age. From these percentages, estimates of length of stay are provided as the number of days following birth and corrected gestational age at discharge. CONCLUSIONS: These results can be used in the counselling of parents about length of stay and the risk of mortality. PMID- 29588301 TI - Leiomyosarcoma: a rare sinonasal malignancy. AB - Leiomyosarcomas (LMS) are rare sinonasal malignant tumours with 20 cases of nasal LMS previously reported in the literature. An 81-year-old man presented with an incidental left nasal lesion associated with left nasal obstruction and occasional left-sided blood-stained rhinorrhoea. Nasendoscopic examination showed green coloured polyps filling the left nasal cavity with biopsies showing LMS. CT imaging did not show any bony erosion. No metastases were found on positron emission tomography imaging. The patient underwent endoscopic resection and all surgical margins were clear of disease. The patient was declined postoperative radiotherapy, and serial follow-up has not shown any recurrence to date. Nasal LMS are rare sinonasal smooth muscle tumours and symptoms and radiological findings are often non-specific. Therefore, diagnosis is made on histopathological and immunohistochemical analysis. Due to their invasive nature, the treatment of choice is complete surgical resection, with adjuvant therapy reserved for patients with locally advanced or metastatic disease.

PMID- 29588305 TI - Appendicitis before Age 20 Years Is Associated with an Increased Risk of Later Prostate Cancer. AB - Background: Appendicitis before age 20 years has been observed to influence the risk of several inflammatory conditions, possibly through underlying immunological mechanisms. Inflammation has further been suggested to be involved in prostate cancer development. We therefore hypothesized that immunological characteristics signaled by appendicitis before late adolescence might influence the risk of later prostate cancer, and aimed to evaluate this association in a population-based study.Methods: We identified a large cohort of Swedish men who underwent assessment for military conscription around the age of 18 years (n = 242,573). Medical diagnoses at time of conscription were available through the Swedish Military Conscription Register. The Swedish Cancer Register was used to identify diagnoses of prostate cancer. Multivariable adjusted Cox regression analyses were used to estimate HR and 95% confidence intervals (95% CIs) for the association between appendicitis and prostate cancer.Results: During a median of 36.7 years of follow-up, 1,684 diagnoses of prostate cancer occurred. We found a statistically significant association between appendicitis and overall prostate cancer (adjusted HR 1.70; 95% CI, 1.08-2.67). The risk was notably increased for advanced (HR 4.42; 95% CI, 1.74-11.22) and lethal (HR 8.95; 95% CI, 2.98-26.91) prostate cancer.Conclusions: These results suggest that a diagnosis of appendicitis before adulthood potentially signals underlying immune characteristics and a pattern of inflammatory response relevant to prostate cancer risk.Impact: The study lends support to the proposed role of inflammation in prostate carcinogenesis, and adds another area of investigation potentially relevant to prostate cancer development.

AB - Very low-dose (VLD) factor Xa (FXa) inhibition, in combination with acetylsalicylic acid (ASA) and clopidogrel, is associated with improved outcomes in patients with acute coronary syndrome (ACS) with a tolerable bleeding risk profile. To date, there are no data documenting platelet inhibition and the anticoagulatory effects of VLD FXa inhibition on top of guideline-adherent dual antiplatelet therapy (DAPT) in patients with ACS. Patients with non-ST-elevation myocardial infarction (NSTEMI) receiving oral DAPT (ASA + clopidogrel, n = 20; or ASA + ticagrelor, n = 20) were prospectively enrolled in a nonrandomized study. Coagulation- and platelet-dependent thrombin generation (TG), measured by means of the calibrated automated thrombogram, were significantly decreased after in vitro and in vivo addition of rivaroxaban. As shown by a total thrombus-formation analysis approach, rivaroxaban treatment led to a significantly decreased coagulation-dependent (AR-chip) thrombus formation in patients treated with ASA plus P2Y12 inhibitor (clopidogrel/ticagrelor), whereas the pure platelet dependent (PL-chip) thrombus formation was not affected at all. Adjunctive rivaroxaban therapy was not associated with significant differences in platelet aggregation assessed by light-transmission aggregometry (LTA). Nevertheless, according to fluorescence-activated cell sorter analysis, VLD rivaroxaban treatment resulted in a significantly reduced expression of platelet HMGB-1, whereas P-selectin exposure was not affected. Furthermore, an enhanced effect of rivaroxaban on total thrombus formation and TG was observed in particular in clopidogrel nonresponder patients defined as adenosine 5'-diphosphate-induced LTA >=40%. VLD rivaroxaban reduces thrombus formation and platelet-dependent TG in patients with ACS receiving DAPT, which can be of potential ischemic benefit. This trial was registered at www.clinicaltrials.gov as #NCT01417884. PMID- 29588306 TI - Hepatitis C Virus Screening Trends: Serial Cross-Sectional Analysis of the National Health Interview Survey Population, 2013-2015. AB - Background: Rates of hepatitis C virus (HCV) infection are markedly higher for baby boomers compared with other birth cohorts, and they are now recommended for universal one-time screening. This study examines HCV screening rates and predictors for four birth cohorts [born <1945, born 1945-1965 (baby boomers), born 1966-1985, and born >1985] of a nationally representative sample over time.Methods: We used data from the 2013-2015 National Health Interview Surveys, an annual weighted survey of the U.S. civilian noninstitutionalized population. We assessed HCV screening prevalence stratified birth cohort with bivariate and multivariable logistic regression analyses.Results: There were 15,100 participants born <1945, 28,725 baby boomers, 28,089 born 1966-1985, and 13,296 born >1985 in the final analytic sample. Screening was 11.5%-12.8% for baby boomers. The second youngest birth cohort was similar to baby boomers (13.7% 14.9%), whereas the older birth cohort was screened less. After excluding participants who typically have higher rates of HCV screening than the general population, we developed a multivariable model of the general population. In the final model for baby boomers the odds of HCV screening increased significantly with each subsequent year (OR=1.20; 95% CI=1.05-1.38 and OR=1.31; 95% CI=1.13 1.52). HCV screening was also significantly associated with age, gender, and race/ethnicity in baby boomers.Conclusions: While HCV screening is increasing over time, these increases are minimal and there is substantial room for improvement.Impact: Future research should develop interventions to increase HCV screening with special focus on groups demonstrating significantly lower screening rates, such as Hispanics and females.

AB - FGFR-TACC fusions, including FGFR3-TACC3, have been identified as potential oncogenic drivers and actionable alterations in a number of different cancer types. The clinical relevance of FGFR3-TACC3 fusions in endometrial cancer has not yet been described. Formalin-fixed, paraffin-embedded metastatic endometrial carcinoma from the spleen and peritoneum were sent for comprehensive genomic profiling (CGP) using the FoundationOne platform as part of a prospective tumor genomic profiling protocol. We report the identification of an FGFR3-TACC3 fusion in a case of metastatic endometrioid endometrial cancer. Other potentially actionable alterations detected in this specimen included PIK3CA T1025S and an uncharacterized rearrangement involving TSC2 The patient initially received an FGFR inhibitor as an investigational agent and experienced stable disease with complete resolution of a pelvic nodule; however, treatment had to be discontinued because of intolerable side effects. A PET/CT scan nearly 3 mo after discontinuation showed disease progression. She subsequently received the mTOR inhibitor, temsirolimus, later accompanied by letrozole, and achieved stable disease. Clinical benefit was attributed to the mTOR inhibitor as tumor stained negative for estrogen receptor. Temsirolimus was discontinued after >17 mo because of disease progression. FGFR inhibitors may have clinical benefit in the treatment of endometrial carcinoma with FGFR3-TACC3 fusions. Additionally, clinical benefit from an mTOR inhibitor may reflect a response to targeting the alteration in PIK3CA or TSC2 More research is needed to understand the activity of FGFR3-TACC3 fusions on tumors and to discover additional therapeutic options for endometrial carcinoma patients with this gene fusion. PMID- 29588308 TI - Exome Sequencing of Plasma DNA Portrays the Mutation Landscape of Colorectal Cancer and Discovers Mutated VEGFR2 Receptors as Modulators of Antiangiogenic Therapies. AB - Purpose: Despite the wide use of antiangiogenic drugs in the clinical setting, predictive biomarkers of response to these drugs are still unknown.Experimental Design: We applied whole-exome sequencing of matched germline and basal plasma cell-free DNA samples (WES-cfDNA) on a RAS/BRAF/PIK3CA wild-type metastatic colorectal cancer patient with primary resistance to standard treatment regimens, including inhibitors to the VEGF:VEGFR2 pathway. We performed extensive functional experiments, including ectopic expression of VEGFR2 mutants in different cell lines, kinase and drug sensitivity assays, and cell- and patient derived xenografts.Results: WES-cfDNA yielded a 77% concordance rate with tumor exome sequencing and enabled the identification of the KDR/VEGFR2 L840F clonal, somatic mutation as the cause of therapy refractoriness in our patient. In addition, we found that 1% to 3% of samples from cancer sequencing projects harbor KDR somatic mutations located in protein residues frequently mutated in other cancer-relevant kinases, such as EGFR, ABL1, and ALK. Our in vitro and in vivo functional assays confirmed that L840F causes strong resistance to antiangiogenic drugs, whereas the KDR hot-spot mutant R1032Q confers sensitivity to strong VEGFR2 inhibitors. Moreover, we showed that the D717V, G800D, G800R, L840F, G843D, S925F, R1022Q, R1032Q, and S1100F VEGFR2 mutants promote tumor growth in mice.Conclusions: Our study supports WES-cfDNA as a powerful platform for portraying the somatic mutation landscape of cancer and discovery of new resistance mechanisms to cancer therapies. Importantly, we discovered that VEGFR2 is somatically mutated across tumor types and that VEGFR2 mutants can be oncogenic and control sensitivity/resistance to antiangiogenic drugs.

AB - Disorders of the pericardium represent a diverse range of conditions that traditionally may not have received the same level of attention by cardiologists and physicians, owing partly to a lack of research into advanced diagnostic modalities, and limited, evidence-based treatment options. In recent years, there has been a timely resurgence of interest in pericardial diseases, in particular pericarditis. This is attributable to advances in multi-modality cardiovascular imaging, in particular cardiac magnetic resonance (CMR), which may help guide treatment decisions for patients with pericardial syndromes. Additionally, increased research and understanding of the pathophysiological basis of pericarditis have shed light on the role of inflammation in pericarditis. This knowledge may help identify potential specific treatment targets. This article aims to provide a practical review of the role of multimodality cardiovascular imaging (echocardiography, multidetector cardiac computed tomography (MDCT), CMR) in pericardial conditions, focusing on the strengths and potential limitations of each imaging modality. PMID- 29588310 TI - Echocardiographic approach to catheter closure of atrial septal defects: patient selection, procedural guidance and post-procedural checks. AB - Echocardiography is the imaging modality of choice to diagnose different types of atrial septal defect and to determine which defects are suitable for catheter occlusion. In addition to assessment of defect size and rims, transoesophageal echocardiography may be used to guide the procedure itself including device placement, procedural complications and post-procedural checks. This review covers a practical approach to this subject and is accompanied by online videos illustrating the technique. PMID- 29588311 TI - Risk of Stroke or Death Is Associated With the Timing of Carotid Artery Stenting for Symptomatic Carotid Stenosis: A Secondary Data Analysis of the German Statutory Quality Assurance Database. AB - BACKGROUND: Subgroup analyses from randomized trials indicate that the time interval between the neurologic index event and carotid artery stenting is associated with periprocedural stroke and death rates in patients with symptomatic carotid stenosis. The aim of this article is to analyze whether this observation holds true under routine conditions in Germany. METHODS AND RESULTS: Secondary data analysis was done on 4717 elective carotid artery stenting procedures that were performed for symptomatic carotid stenosis. The patient cohort was divided into 4 groups according to the time interval between the index event and intervention (group I 0-2, II 3-7, III 8-14, and IV 15-180 days). Primary outcome was any in-hospital stroke or death. For risk-adjusted analyses, a multilevel multivariable regression model was used. The in-hospital stroke or death rate was 3.7% in total and 6.0%, 4.4%, 2.4%, and 3.0% in groups I, II, III, and IV, respectively. Adjusted analysis showed a decreased risk for any stroke or death in group III, a decreased risk for any major stroke or death in groups III and IV, and a decreased risk for any death in groups II and III compared to the reference group I. CONCLUSIONS: A short time interval between the neurologic index event and carotid artery stenting of up to 7 days is associated with an increased risk for stroke or death under routine conditions in Germany. Although results cannot prove causal relationships, carotid artery stenting may be accompanied by an increased risk of stroke or death during the early period after the index event. PMID- 29588312 TI - Clustered Emergency Room Visits Following an Acute Heart Failure Admission: A Population-Based Study. AB - BACKGROUND: While it is well known that heart failure patients presenting to the emergency room (ER) have high short-term mortality after discharge, the outcomes of patients with heart failure with repeated ER visits within a short time are not known. In this study, we aimed to determine whether clustering is associated with an increased risk of death. METHODS AND RESULTS: This is a retrospective, population-based cohort study with an accrual window between 2003 and 2014 and maximal follow-up up to and including March 31, 2015. Data were obtained from administrative databases from Ontario, Canada. Clustering was defined a priori as 3 or more ER visits within a 6-month period. The main outcome of interest was time to death conditional on 6-month survival. A total of 72 810 patients with an index hospitalization for acute heart failure were evaluated. ER clustering was observed in 15.1% of the population. Increased burden of comorbidities, primary rural residence, and lack of primary care provider were identified as factors associated with ER clustering. Age- and sex-adjusted mortality for clustered patients was higher than for nonclustered (hazard ratio [HR] 1.51; 95% confidence interval, 1.47-1.55, P<0.0001). Adjusted mortality risk was also higher for patients with clustered ER visits (HR 1.42; 95% confidence interval 1.38-1.46; P<0.0001). CONCLUSIONS: Clustering, as defined by 3 or more ER visits for any reason within 6 months of index heart failure hospitalization reflects a novel risk factor associated with increased mortality. Future research into the strategies to better manage complex patients with heart failure with recurrent ER visits are warranted. PMID- 29588313 TI - Reliability and Physiological Interpretation of Pulmonary Gas Exchange by "Circulatory Equivalents" in Chronic Heart Failure. AB - BACKGROUND: Peak ratios of pulmonary gas-exchange to ventilation during exercise (VO2/VE and VCO2/VE, termed "circulatory equivalents") are sensitive to heart failure (HF) severity, likely reflecting low and/or poorly distributed pulmonary perfusion. We tested whether peak VO2/VE and VCO2/VE would: (1) distinguish HF patients from controls; (2) be independent of incremental exercise protocol; and (3) correlate with lactate threshold (LT) and ventilatory compensation point (VCP), respectively. METHODS AND RESULTS: Twenty-four HF patients (61+/-11 years) with reduced ejection fraction (31+/-8%) and 11 controls (63+/-7 years) performed ramp-incremental cycle ergometry. Eighteen HF patients also performed slow (5+/-1 W/min), medium (9+/-4 W/min), and fast (19+/-6 W/min) ramps. Peak VO2/VE and VCO2/VE from X-Y plot, and LT and VCP from 9-panel plot, were determined by 2 independent, blinded, assessors. Peak VO2/VE (31.2+/-4.4 versus 41.8+/-4.8 mL/L; P<0.0001) and VCO2/VE (29.3+/-3.0 versus 36.9+/-4.0 mL/L; P<0.0001) were lower in HF than controls. Within individuals, there was no difference across 3 ramp rates in peak VO2/VE (P=0.62) or VCO2/VE (P=0.97). Coefficient of variation (CV) in peak VO2/VE was lower than for LT (5.1+/-2.1% versus 8.2+/-3.7%; P=0.014), and coefficient of variation in peak VCO2/VE was lower than for VCP (3.3+/-1.8% versus 8.7+/-4.2%; P<0.001). In all participants, peak VO2/VE was correlated with, but occurred earlier than, LT (r2=0.94; mean bias, -0.11 L/min), and peak VCO2/VE was correlated with, but occurred earlier than, VCP (r2=0.98; mean bias 0.08 L/min). CONCLUSIONS: Peak circulatory equivalents during exercise are strongly associated with (but not identical to) LT and VCP. Peak circulatory equivalents are reliable, objective, effort-independent indices of gas-exchange abnormality in HF. PMID- 29588314 TI - Comparison of Time-to-First Event and Recurrent-Event Methods in Randomized Clinical Trials. AB - BACKGROUND: Most phase-3 trials feature time-to-first event end points for their primary and secondary analyses. In chronic diseases, where a clinical event can occur >1 time, recurrent-event methods have been proposed to more fully capture disease burden and have been assumed to improve statistical precision and power compared with conventional time-to-first methods. METHODS: To better characterize factors that influence statistical properties of recurrent-event and time-to first methods in the evaluation of randomized therapy, we repeatedly simulated trials with 1:1 randomization of 4000 patients to active versus control therapy, with true patient-level risk reduction of 20% (ie, relative risk=0.80). For patients who discontinued active therapy after a first event, we assumed their risk reverted subsequently to their original placebo-level risk. Through simulation, we varied the degree of between-patient heterogeneity of risk and the extent of treatment discontinuation. Findings were compared with those from actual randomized clinical trials. RESULTS: As the degree of between-patient heterogeneity of risk increased, both time-to-first and recurrent-event methods lost statistical power to detect a true risk reduction and confidence intervals widened. The recurrent-event analyses continued to estimate the true relative risk (0.80) as heterogeneity increased, whereas the Cox model produced attenuated estimates. The power of recurrent-event methods declined as the rate of study drug discontinuation postevent increased. Recurrent-event methods provided greater power than time-to-first methods in scenarios where drug discontinuation was <=30% after a first event, lesser power with drug discontinuation rates of >=60%, and comparable power otherwise. We confirmed in several actual trials of chronic heart failure that treatment effect estimates were attenuated when estimated via the Cox model and that increased statistical power from recurrent event methods was most pronounced in trials with lower treatment discontinuation rates. CONCLUSIONS: We find that the statistical power of both recurrent-events and time-to-first methods are reduced by increasing heterogeneity of patient risk, a parameter not included in conventional power and sample size formulas. Data from real clinical trials are consistent with simulation studies, confirming that the greatest statistical gains from use of recurrent-events methods occur in the presence of high patient heterogeneity and low rates of study drug discontinuation. PMID- 29588315 TI - Cholesterol Efflux Pathways Suppress Inflammasome Activation, NETosis, and Atherogenesis. AB - BACKGROUND: The CANTOS trial (Canakinumab Antiinflammatory Thrombosis Outcome Study) showed that antagonism of interleukin (IL)-1beta reduces coronary heart disease in patients with a previous myocardial infarction and evidence of systemic inflammation, indicating that pathways required for IL-1beta secretion increase cardiovascular risk. IL-1beta and IL-18 are produced via the NLRP3 inflammasome in myeloid cells in response to cholesterol accumulation, but mechanisms linking NLRP3 inflammasome activation to atherogenesis are unclear. The cholesterol transporters ATP binding cassette A1 and G1 (ABCA1/G1) mediate cholesterol efflux to high-density lipoprotein, and Abca1/g1 deficiency in myeloid cells leads to cholesterol accumulation. METHODS: To interrogate mechanisms connecting inflammasome activation with atherogenesis, we used mice with myeloid Abca1/g1 deficiency and concomitant deficiency of the inflammasome components Nlrp3 or Caspase-1/11. Bone marrow from these mice was transplanted into Ldlr-/- recipients, which were fed a Western-type diet. RESULTS: Myeloid Abca1/g1 deficiency increased plasma IL-18 levels in Ldlr-/- mice and induced IL 1beta and IL-18 secretion in splenocytes, which was reversed by Nlrp3 or Caspase 1/11 deficiency, indicating activation of the NLRP3 inflammasome. Nlrp3 or Caspase-1/11 deficiency decreased atherosclerotic lesion size in myeloid Abca1/g1 deficient Ldlr-/- mice. Myeloid Abca1/g1 deficiency enhanced caspase-1 cleavage not only in splenic monocytes and macrophages, but also in neutrophils, and dramatically enhanced neutrophil accumulation and neutrophil extracellular trap formation in atherosclerotic plaques, with reversal by Nlrp3 or Caspase-1/11 deficiency, suggesting that inflammasome activation promotes neutrophil recruitment and neutrophil extracellular trap formation in atherosclerotic plaques. These effects appeared to be indirectly mediated by systemic inflammation leading to activation and accumulation of neutrophils in plaques. Myeloid Abca1/g1 deficiency also activated the noncanonical inflammasome, causing increased susceptibility to lipopolysaccharide-induced mortality. Patients with Tangier disease, who carry loss-of-function mutations in ABCA1 and have increased myeloid cholesterol content, showed a marked increase in plasma IL-1beta and IL 18 levels. CONCLUSIONS: Cholesterol accumulation in myeloid cells activates the NLRP3 inflammasome, which enhances neutrophil accumulation and neutrophil extracellular trap formation in atherosclerotic plaques. Patients with Tangier disease, who have increased myeloid cholesterol content, showed markers of inflammasome activation, suggesting human relevance. PMID- 29588317 TI - Spatiotemporal Multi-omics Mapping Generates a Molecular Atlas of the Aortic Valve and Reveals Networks Driving Disease. AB - Background -No pharmacological therapy exists for calcific aortic valve disease (CAVD), which confers a dismal prognosis without invasive valve replacement. The search for therapeutics and early diagnostics is challenging since CAVD presents in multiple pathological stages. Moreover, it occurs in the context of a complex, multi-layered tissue architecture, a rich and abundant extracellular matrix phenotype, and a unique, highly plastic and multipotent resident cell population. Methods -A total of 25 human stenotic aortic valves obtained from valve replacement surgeries were analyzed by multiple modalities, including transcriptomics and global unlabeled and label-based tandem-mass-tagged proteomics. Segmentation of valves into disease-stage-specific samples was guided by near infrared molecular imaging, and anatomical layer-specificity was facilitated by laser capture microdissection. Side-specific cell cultures were subjected to multiple calcifying stimuli, and their calcification potential and basal/stimulated proteomes were evaluated. Molecular (protein-protein) interaction networks were built and their central proteins and disease associations were identified. Results -Global transcriptional and protein expression signatures differed between the non-diseased, fibrotic, and calcific stages of CAVD. Anatomical aortic valve microlayers exhibited unique proteome profiles that were maintained throughout disease progression and identified glial fibrillary acidic protein (GFAP) as a specific marker of valvular interstitial cells (VICs) from the spongiosa layer. CAVD disease progression was marked by an emergence of smooth muscle cell activation, inflammation, and calcification related pathways. Proteins overrepresented in the disease-prone fibrosa are functionally annotated to fibrosis and calcification pathways, and we found that in vitro, fibrosa-derived VICs demonstrated greater calcification potential than those from the ventricularis. These studies confirmed that the microlayer specific proteome was preserved in cultured VICs, and that VICs exposed to ALPL dependent and ALPL-independent calcifying stimuli had distinct proteome profiles, both of which overlapped with that of the whole tissue. Analysis of protein protein interaction networks found a significant closeness to multiple inflammatory and fibrotic diseases. Conclusions -A spatially- and temporally resolved multi-omics, and network and systems biology strategy identifies the first molecular regulatory networks in CAVD, a cardiac condition without a pharmacological cure, and describes a novel means of systematic disease ontology that is broadly applicable to comprehensive omics studies of cardiovascular diseases. PMID- 29588316 TI - Regulatory CD4+ T Cells Recognize Major Histocompatibility Complex Class II Molecule-Restricted Peptide Epitopes of Apolipoprotein B. AB - BACKGROUND: CD4+ T cells play an important role in atherosclerosis, but their antigen specificity is poorly understood. Immunization with apolipoprotein B (ApoB, core protein of low density lipoprotein) is known to be atheroprotective in animal models. Here, we report on a human APOB peptide, p18, that is sequence identical in mouse ApoB and binds to both mouse and human major histocompatibility complex class II molecules. METHODS: We constructed p18 tetramers to detect human and mouse APOB-specific T cells and assayed their phenotype by flow cytometry including CD4 lineage transcription factors, intracellular cytokines, and T cell receptor activation. Apolipoprotein E deficient ( Apoe-/-) mice were vaccinated with p18 peptide or adjuvants alone, and atherosclerotic burden in the aorta was determined. RESULTS: In human peripheral blood mononuclear cells from donors without cardiovascular disease, p18 specific CD4+ T cells detected by a new human leukocyte antigen-antigen D related-p18 tetramers were mostly Foxp3+ regulatory T cells (Tregs). Donors with subclinical cardiovascular disease as detected by carotid artery ultrasound had Tregs coexpressing retinoic acid-related orphan receptor gamma t or T-bet, which were both almost absent in donors without cardiovascular disease. In Apoe-/- mice, immunization with p18 induced Tregs and reduced atherosclerotic lesions. After peptide restimulation, responding CD4+ T cells identified by Nur77-GFP (green fluorescent protein) were highly enriched in Tregs. A new mouse I-Ab-p18 tetramer identified the expansion of p18-specific CD4+ T cells on vaccination, which were enriched for interleukin-10-producing Tregs. CONCLUSIONS: These findings show that APOB p18-specific CD4+ T cells are mainly Tregs in healthy donors, but coexpress other CD4 lineage transcription factors in donors with subclinical cardiovascular disease. This study identifies ApoB peptide 18 as the first Treg epitope in human and mouse atherosclerosis.

AB - T cells genetically engineered with tumor antigen-specific T-cell receptor (TCR) genes have demonstrated therapeutic potential in patients with solid tumors. In order to achieve broader application, an efficient method to identify TCR genes for an array of tumor antigens and HLA restriction elements is required. Here, we have developed a method to construct a TCR-expression library from specimens, including frozen tumor biopsies, that contain antigen-specific T cells. TCR expressing cassettes were constructed and cloned in a retroviral plasmid vector within 24 hours by unbiased PCR amplification of TCR alpha and beta chain variable regions assembled with TCR constant regions. The method was validated by constructing TCR-expressing vectors from tumor antigen-specific T-cell clones and functionally assessing TCR gene-transduced T cells. We applied this method to frozen ovarian tumor specimens that were infiltrated by tumor antigen-specific T cells. The tumor-derived TCR libraries were expressed in peripheral T cells from healthy volunteers and screened for tumor antigen-specific TCR pairs with the use of an MHC/peptide tetramer reagent. Tumor antigen-specific TCR-expressing transgenes were recovered from isolated tetramer-positive T cells. Peripheral T cells that were engineered with library-derived TCR gene showed potent therapeutic antitumor effect in a tumor xenograft model. Our method can efficiently and rapidly provide tumor-specific TCR-expressing viral vectors for the manufacture of therapeutic and personalized antitumor T-cell products.

AB - T cells expressing chimeric antigen receptors (CART) have shown significant promise in clinical trials to treat hematologic malignancies, but their efficacy in solid tumors has been limited. Oncolytic viruses have the potential to act in synergy with immunotherapies due to their immunogenic oncolytic properties and the opportunity of incorporating therapeutic transgenes in their genomes. Here, we hypothesized that an oncolytic adenovirus armed with an EGFR-targeting, bispecific T-cell engager (OAd-BiTE) would improve the outcome of CART-cell therapy in solid tumors. We report that CART cells targeting the folate receptor alpha (FR-alpha) successfully infiltrated preestablished xenograft tumors but failed to induce complete responses, presumably due to the presence of antigen negative cancer cells. We demonstrated that OAd-BiTE-mediated oncolysis significantly improved CART-cell activation and proliferation, while increasing cytokine production and cytotoxicity, and showed an in vitro favorable safety profile compared with EGFR-targeting CARTs. BiTEs secreted from infected cells redirected CART cells toward EGFR in the absence of FR-alpha, thereby addressing tumor heterogeneity. BiTE secretion also redirected CAR-negative, nonspecific T cells found in CART-cell preparations toward tumor cells. The combinatorial approach improved antitumor efficacy and prolonged survival in mouse models of cancer when compared with the monotherapies, and this was the result of an increased BiTE-mediated T-cell activation in tumors. Overall, these results demonstrated that the combination of a BiTE-expressing oncolytic virus with adoptive CART-cell therapy overcomes key limitations of CART cells and BiTEs as monotherapies in solid tumors and encourage its further evaluation in human trials.

AB - Regulatory T cells (Treg) have long been considered one-sided suppressors of antitumor immune responses and hence associated with poor patient outcome in cancer. However, evidence is mounting of a paradoxical positive prognostic effect of Tregs on certain malignancies, including urinary bladder cancer (UBC). This discrepancy has partly been attributed to the shear misidentification of Tregs, but also to the inflammatory profile of the tumor. Our aim was to determine whether tumor-infiltrating Forkhead box P3+ (FOXP3+) cells confer a stable Treg phenotype and to investigate putative beneficial Treg functions, focusing on tumor-promoting inflammatory pathways in UBC. Patients (n = 52) with suspected UBC were prospectively included. We show, by using a broad range of analytical approaches, that tumor-infiltrating CD4+FOXP3+ T cells in UBC phenotypically, functionally, and epigenetically represent a true Treg population. At the invasive front of UBC tumors, we found an inverse relationship between Treg frequency and expression of matrix metalloproteinase 2 (MMP2), a key proinvasive factor induced by tumor-promoting inflammation. Correspondingly, a significant, dose-dependent Treg-mediated downregulation of MMP2 protein and mRNA expression was observed in both macrophages and UBC cells. Also, we found that Treg frequency specifically at the invasive front positively correlated with survival. Thus, we identify Treg-mediated suppression of MMP2 in the tumor microenvironment as a mechanism explaining the paradoxical positive prognostic impact of tumor infiltrating Tregs in UBC.

AB - Although tumor-associated macrophages (TAM) display a M2-skewed tumor-promoting phenotype in most cancers, in colorectal cancer, both TAM polarization and its impact remain controversial. We investigated the role of the M2-polarizing p50 NF kappaB subunit in orchestrating TAM phenotype, tumor microenvironment composition, and colorectal cancer progression. We first demonstrated, by parallel studies in colitis-associated cancer (CAC) and in genetically driven ApcMin mouse models, that the p50-dependent inhibition of M1-polarized gut inflammation supported colorectal cancer development. In accordance with these studies, p50-/- mice displayed exacerbated CAC with fewer and smaller tumors, along with enhanced levels of M1/Th1 cytokines/chemokines, including IL12 and CXCL10, whose administration restrained CAC development in vivo The inflammatory profile supporting tumor resistance in colons from p50-/- tumor bearers correlated inversely with TAM load and positively with both recruitment of NK, NKT, CD8+ T cells and number of apoptotic tumor cells. In agreement, myeloid specific ablation of p50 promoted tumor resistance in mice, whereas in colorectal cancer patients, a high number of p50+ TAMs at the invasive margin was associated with decreased IL12A and TBX21 expression and worse postsurgical outcome. Our findings point to p50 involvement in colorectal cancer development, through its engagement in the protumor activation of macrophages, and identify a candidate for prognostic and target therapeutic intervention.

PMID- 29588323 TI - Interagency collaboration models for people with mental ill health in contact with the police: a systematic scoping review. AB - OBJECTIVE: To identify existing evidence on interagency collaboration between law enforcement, emergency services, statutory services and third sector agencies regarding people with mental ill health. DESIGN: Systematic scoping review. Scoping reviews map particular research areas to identify research gaps. DATA SOURCES AND ELIGIBILITY: ASSIA, CENTRAL, the Cochrane Library databases, Criminal Justice Abstracts, ERIC, Embase, MEDLINE, PsycINFO, PROSPERO and Social Care Online and Social Sciences Citation Index were searched up to 2017, as were grey literature and hand searches. Eligible articles were empirical evaluations or descriptions of models of interagency collaboration between the police and other agencies. STUDY APPRAISAL AND SYNTHESIS: Screening and data extraction were undertaken independently by two researchers. Arksey's framework was used to collate and map included studies. RESULTS: One hundred and twenty-five studies were included. The majority of articles were of descriptions of models (28%), mixed methods evaluations of models (18%) and single service evaluations (14%). The most frequently reported outcomes (52%) were 'organisational or service level outcomes' (eg, arrest rates). Most articles (53%) focused on adults with mental ill health, whereas others focused on adult offenders with mental ill health (17.4%). Thirteen models of interagency collaboration were described, each involving between 2 and 13 agencies. Frequently reported models were 'prearrest diversion' of people with mental ill health (34%), 'coresponse' involving joint response by police officers paired with mental health professionals (28.6%) and 'jail diversion' following arrest (23.8%). CONCLUSIONS: We identified 13 different interagency collaboration models catering for a range of mental health related interactions. All but one of these models involved the police and mental health services or professionals. Several models have sufficient literature to warrant full systematic reviews of their effectiveness, whereas others need robust evaluation, by randomised controlled trial where appropriate. Future evaluations should focus on health-related outcomes and the impact on key stakeholders. PMID- 29588324 TI - Wisconsin microbiome study, a cross-sectional investigation of dietary fibre, microbiome composition and antibiotic-resistant organisms: rationale and methods. AB - INTRODUCTION: Prevention of multidrug-resistant organism (MDRO) infections, such as those caused by methicillin-resistant Staphylococcus aureus, vancomycin resistant enterococci, fluoroquinolone-resistant Gram-negative bacteria and Clostridium difficile is crucial. Evidence suggests that dietary fibre increases gut microbial diversity, which may help prevent colonisation and subsequent infection by MDROs. The aim of the Winning the War on Antibiotic Resistance (WARRIOR) project is to examine associations of dietary fibre consumption with the composition of the gut microbiota and gut colonisation by MDROs. The secondary purpose of the study is to create a biorepository of multiple body site specimens for future microbiota research. METHODS AND ANALYSIS: The WARRIOR project collects biological specimens, including nasal, oral and skin swabs and saliva and stool samples, along with extensive data on diet and MDRO risk factors, as an ancillary study of the Survey of the Health of Wisconsin (SHOW). The SHOW is a population-based health survey collecting data on several different health determinants and outcomes, as well as objective body measurements and biological specimens. WARRIOR participants include 600 randomly selected Wisconsin residents age 18 and over. Specimens are screened for MDRO colonisation and DNA is extracted for 16S ribosomal RNA-based microbiota sequencing. Data will be analysed to assess the relationship between dietary fibre, the gut microbiota composition and gut MDRO colonisation. ETHICS AND DISSEMINATION: The WARRIOR project is approved by the University of Wisconsin Institutional Review Board. The main results of this study will be published in a peer-reviewed scientific journal. PMID- 29588325 TI - Delineating the trajectories of social and occupational functioning of young people attending early intervention mental health services in Australia: a longitudinal study. AB - OBJECTIVES: Mental disorders typically emerge during adolescence and young adulthood and put young people at risk for prolonged socioeconomic difficulties. This study describes the longitudinal course of social and occupational functioning of young people attending primary care-based, early intervention services. DESIGN: A longitudinal study of young people receiving mental healthcare. SETTING: Data were collected between January 2005 and August 2017 from a designated primary care-based mental health service. PARTICIPANTS: 554 young people (54% women) aged 12-32 years. MEASURES: A systematic medical file audit collected clinical and functional information at predetermined time intervals (ie, 3 months to 5+ years) using a clinical pro forma. Group-based trajectory modelling (GBTM) was used to identify distinct trajectories of social and occupational functioning over time (median number of observations per person=4; median follow-up time=23 months). RESULTS: Between first clinical contact and time last seen, 15% of young people had reliably deteriorated, 23% improved and 62% did not demonstrate substantive change in function. Of the whole cohort, 69% had functional scores less than 70 at time last seen, indicative of ongoing and substantive impairment. GBTM identified six distinct functional trajectories whereby over 60% had moderate-to-serious functional impairment at entry and remained chronically impaired over time; 7% entered with serious impairment and deteriorated further; a quarter were mildly impaired at entry and functionally recovered and only a small minority (4%) presented with serious impairments and functionally improved over time. Not being in education, employment or training, previous hospitalisation and a younger age at baseline emerged as significant predictors of these functional trajectories. CONCLUSION: Young people with emerging mental disorders have significant functional impairment at presentation for care, and for the majority, it persists over the course of clinical care. In addition to providing clinical care earlier in the course of illness, these data suggest that more sophisticated and more intensive individual-level and organisational strategies may be required to achieve significant and sustained functional improvements. PMID- 29588327 TI - Educational attainment of children born to mothers with epilepsy. AB - OBJECTIVE: Small prospective studies have identified that children exposed to valproate in utero have poorer scores on cognitive testing. We wanted to identify whether children exposed to antiepileptic drugs (AEDs) in utero have poorer school performance. METHODS: We used anonymised, linked, routinely collected healthcare records to identify children born to mothers with epilepsy. We linked these children to their national attainment Key Stage 1 (KS1) tests in mathematics, language and science at the age of 7 and compared them with matched children born to mothers without epilepsy, and with the national KS1 results. We used the core subject indicator (CSI) as an outcome measure (the proportion of children achieving a minimum standard in all subjects) and the results in individual subjects. RESULTS: We identified 440 children born to mothers with epilepsy with available KS1 results. Compared with a matched control group, fewer children with mothers being prescribed sodium valproate during pregnancy achieved the national minimum standard in CSI (-12.7% less than the control group), mathematics (-12.1%), language (-10.4%) and in science (-12.2%). Even fewer children with mothers being prescribed multiple AEDs during pregnancy achieved a national minimum standard: CSI (by -20.7% less than the control group), mathematics (-21.9%), language (-19.3%) and science (-19.4%). We did not observe any significant difference in children whose mothers were prescribed carbamazepine or were not taking an AED when compared with the control group. CONCLUSIONS: In utero exposure to AEDs in combination, or sodium valproate alone, is associated with a significant decrease in attainment in national educational tests for 7-year-old children compared with both a matched control group and the all-Wales national average. These results give further support to the cognitive and developmental effects of in utero exposure to sodium valproate as well as multiple AEDs, which should be balanced against the need for effective seizure control for women during pregnancy.

PMID- 29588326 TI - Impact of CAre-related Regret Upon Sleep (ICARUS) cohort study: protocol of a 3 year multicentre, international, prospective cohort study of novice healthcare professionals. AB - INTRODUCTION: Healthcare professionals are particularly at risk of developing numerous physical and psychological health problems. The experiences of emotional burden associated with providing healthcare, notably care-related regret, have been associated with these health problems, but only using cross-sectional data so far. Evidence of a causal impact of regret has not been assessed. The Impact of CAre-related Regret Upon Sleep (ICARUS) study is the first prospective and international cohort study established to examine how newly practising healthcare professionals adapt to their challenging job by assessing the impact of care related regret on sleep and job quitting. METHOD AND ANALYSIS: The ICARUS cohort study will include newly practising healthcare professionals working in acute care hospitals and clinics recruited between May 2017 and November 2019. Data collection, which will begin as soon as the participant starts working with patients, will consist of a 1-year weekly assessment using a secure web survey. Follow-up data will be collected at 6, 12, 18 and 24 months after the end of the first year. We will collect detailed information on the experience of care related regret (ie, highest regret intensity, accumulation of regrets and coping strategies related to regrets), sleep problems and job quitting. Moreover, quality of life, health status and burnout will be assessed during the follow-up. Several confounders factors, including sociodemographic characteristics, personality, night shifts and work environment characteristics, will be assessed. ETHICS AND DISSEMINATION: The study was approved by the Ethics Committee of Geneva Canton, Switzerland (CCER2016-02041), the Ethics Committee of London South Bank University (HSCSEP/17/06) and the University Research Ethics Committee of Bedfordshire (UREC106). Other study centres deemed local ethical approval unnecessary since the main ethics committee (Geneva) had already accepted the project. Results will be published in relevant scientific journals and be disseminated in international conferences. Fully anonymised data and questionnaires will be freely accessible to everyone (scientists and general public). PMID- 29588329 TI - Social isolation and loneliness as risk factors for myocardial infarction, stroke and mortality: UK Biobank cohort study of 479 054 men and women. AB - OBJECTIVE: To examine whether social isolation and loneliness (1) predict acute myocardial infarction (AMI) and stroke among those with no history of AMI or stroke, (2) are related to mortality risk among those with a history of AMI or stroke, and (3) the extent to which these associations are explained by known risk factors or pre-existing chronic conditions. METHODS: Participants were 479 054 individuals from the UK Biobank. The exposures were self-reported social isolation and loneliness. AMI, stroke and mortality were the outcomes. RESULTS: Over 7.1 years, 5731 had first AMI, and 3471 had first stroke. In model adjusted for demographics, social isolation was associated with higher risk of AMI (HR 1.43, 95% CI 1.3 to -1.55) and stroke (HR 1.39, 95% CI 1.25 to 1.54). When adjusted for all the other risk factors, the HR for AMI was attenuated by 84% to 1.07 (95% CI 0.99 to 1.16) and the HR for stroke was attenuated by 83% to 1.06 (95% CI 0.96 to 1.19). Loneliness was associated with higher risk of AMI before (HR 1.49, 95% CI 1.36 to 1.64) but attenuated considerably with adjustments (HR 1.06, 95% CI 0.96 to 1.17). This was also the case for stroke (HR 1.36, 95% CI 1.20 to 1.55 before and HR 1.04, 95% CI 0.91 to 1.19 after adjustments). Social isolation, but not loneliness, was associated with increased mortality in participants with a history of AMI (HR 1.25, 95% CI 1.03 to 1.51) or stroke (HR 1.32, 95% CI 1.08 to 1.61) in the fully adjusted model. CONCLUSIONS: Isolated and lonely persons are at increased risk of AMI and stroke, and, among those with a history of AMI or stroke, increased risk of death. Most of this risk was explained by conventional risk factors. PMID- 29588331 TI - Predictors of prolonged length of hospital stay for infants with bronchiolitis. AB - Among inpatients suffering from bronchiolitis, approximately a quarter may undergo a prolonged length of stay (LOS) for the treatment of their respiratory condition. However, there have been few research studies that have evaluated variables that may be associated with a prolonged LOS in these patients, especially in low-income and middle-income countries, where the clinical and economic burden of the disease is the greatest. In an analytical single-center cross-sectional study, we included a population of patients with acute bronchiolitis hospitalized between March and June 2016. We collected demographic and clinical information and the LOS of each patient. Prolonged LOS for bronchiolitis was defined as at least one hospital stay of 5 or more days. A total of 303 patients were included, with 176 (58.1%) male and a median (IQR) age of 3.0 (1.0-7.0) months. After controlling for gender, history of bronchopulmonary dysplasia, number of days with respiratory symptoms, the presence of apnea as an initial manifestation of bronchiolitis, and other underlying disease conditions, we found that the independent predictors of prolonged LOS for bronchiolitis in our study population included age (OR 0.92; 95% CI 0.84 to 0.99; p=0.049), history of prematurity (OR 6.34; 95% CI 1.10 to 36.46; p=0.038), respiratory syncytial virus isolation (OR 1.92; 95% CI 1.02 to 3.73; p=0.048), and initial oxygen saturation (OR 0.94; 95% CI 0.88 to 0.98; p=0.048). The factors identified should be taken into account when planning policies to reduce the duration of hospital stay in infants with bronchiolitis. PMID- 29588330 TI - ONC201 Targets AR and AR-V7 Signaling, Reduces PSA, and Synergizes with Everolimus in Prostate Cancer. AB - Androgen receptor (AR) signaling plays a key role in prostate cancer progression, and androgen deprivation therapy (ADT) is a mainstay clinical treatment regimen for patients with advanced disease. Unfortunately, most prostate cancers eventually become androgen-independent and resistant to ADT with patients progressing to metastatic castration-resistant prostate cancer (mCRPC). Constitutively activated AR variants (AR-V) have emerged as mediators of resistance to AR-targeted therapy and the progression of mCRPC, and they represent an important therapeutic target. Out of at least 15 AR-Vs described thus far, AR-V7 is the most abundant, and its expression correlates with ADT resistance. ONC201/TIC10 is the founding member of the imipridone class of small molecules and has shown anticancer activity in a broad range of tumor types. ONC201 is currently being tested in phase I/II clinical trials for advanced solid tumors, including mCRPC, and hematologic malignancies. There has been promising activity observed in patients in early clinical testing. This study demonstrates preclinical single-agent efficacy of ONC201 using in vitro and in vivo models of prostate cancer. ONC201 has potent antiproliferative and proapoptotic effects in both castration-resistant and -sensitive prostate cancer cells. Furthermore, the data demonstrate that ONC201 downregulates the expression of key drivers of prostate cancer such as AR-V7 and downstream target genes including the clinically used biomarker PSA (KLK3). Finally, the data also provide a preclinical rationale for combination of ONC201 with approved therapeutics for prostate cancer such as enzalutamide, everolimus (mTOR inhibitor), or docetaxel.Implications: The preclinical efficacy of ONC201 as a single agent or in combination, in hormone-sensitive or castration-resistant prostate cancer, suggests the potential for immediate clinical translation.

AB - Early life events play a crucial role in the development of irritable bowel syndrome (IBS). Some evidence suggests the phenomenon of cross-organ sensitization between bladder and colon. Whether urinary tract infection (UTI) during infancy is a risk factor of childhood IBS remains to be elucidated. In this retrospective cohort study, we selected 31 788 infants who had UTI between 2000 and 2011 as a UTI cohort and selected 127 152 infants without UTI as a comparison cohort, matched by age, sex and level of urbanization of living area. Incidence density and HRs with CIs of IBS between UTI and non-UTI cohorts were calculated by the end of 2012. The incidence density of IBS during the study period was 1.52-fold higher in the UTI cohort (95% CI 1.38 to 1.67) compared with the non-UTI cohort (2.05 vs 1.32 per 10 000 person-years). The HR of IBS was slightly higher for boys (1.53; 95% CI 1.34 to 1.73) than for girls (1.50; 95% CI 1.29 to 1.73). The HRs for IBS in children with UTI were greater for those with more UTI-related medical visits/per year (>5 visits, HR 61.3; 95% CI 51.8 to 72.6), with longer length of stay of hospitalization (>7 days, HR 1.75; 95% CI 1.36 to 2.24) and with vesicoureteral reflux (VUR) (HR 1.73; 95% CI 1.35 to 2.22) (p<0.0001, the trend test). Infants with UTI had higher risks of childhood IBS and the risks elevated further with recurrent UTI or UTI with concurrent VUR. PMID- 29588333 TI - Case-control investigation of occupational exposure to chlorinated solvents and non-Hodgkin's lymphoma. AB - OBJECTIVES: Although many studies have investigated the association between trichloroethylene (TCE) exposure and non-Hodgkin's lymphoma (NHL), less is known about other chlorinated solvents. We extended our previous analysis of occupational TCE exposure in a multicentre population-based case-control study of NHL to investigate associations with five additional chlorinated solvents: 1,1,1, trichloroethane, carbon tetrachloride, chloroform, methylene chloride and perchloroethylene. METHODS: Cases (n=1189) and controls (n=982) provided detailed information on their occupational histories and workplace exposure to chlorinated solvents for selected occupations using job-specific interview modules. An industrial hygienist used this information and a review of the literature to assess occupational exposure to chlorinated solvents. We computed ORs and 95% CIs for different exposure metrics, with the unexposed group as the referent. We also computed ORs by NHL subtype. RESULTS: High cumulative hours exposed to carbon tetrachloride was associated with NHL (>520 hours: OR 1.9; 95% CI 1.0 to 3.6; Ptrend=0.04). This association remained after restricting to jobs with high intensity exposure (OR 2.0; 95% CI 1.1 to 3.8; P=0.03) and >=90% exposure probability (OR 2.1; 95% CI 1.0 to 4.3; P=0.03), adjusting for TCE (OR 2.1; 95% CI 1.0- to 4.1; P=0.04) and incorporating a 15-year lag (OR 1.9; 95% CI 1.0 to 3.6; P=0.06). The other evaluated chlorinated solvents were not associated with NHL. CONCLUSIONS: This is the first study using high-quality quantitative exposure assessment methods to identify a statistically significant elevated association between occupational exposure to carbon tetrachloride and NHL. Our findings, although limited by a small number of exposed cases, offer evidence that carbon tetrachloride may be a lymphomagen.

PMID- 29588335 TI - The Potato MAP3K StVIK Is Required for the Phytophthora infestans RXLR Effector Pi17316 to Promote Disease. AB - Plant pathogens deliver effectors to manipulate processes in their hosts, creating a suitable environment for invasion and proliferation. Yet, little is known about the host proteins that are targeted by effectors from filamentous pathogens. Here, we show that stable transgenic expression in potato (Solanum tuberosum) and transient expression in Nicotiana benthamiana of the arginine-any amino acid-leucine-arginine effector Pi17316 enhances leaf colonization by the late blight pathogen Phytophthora infestans Expression of Pi17316 also attenuates cell death triggered by the pathogen-associated molecular pattern Infestin1 (INF1), indicating that the effector suppresses pattern-triggered immunity. However, this effector does not attenuate cell death triggered by a range of resistance proteins, showing that it specifically suppresses INF1-triggered cell death (ICD). In yeast two-hybrid assays, Pi17316 interacts directly with the potato ortholog of VASCULAR HIGHWAY1-interacting kinase (StVIK), encoding a predicted MEK kinase (MAP3K). Interaction in planta was confirmed by coimmunoprecipitation and occurs at the plant plasma membrane. Virus-induced gene silencing of VIK in N. benthamiana attenuated P. infestans colonization, whereas transient overexpression of StVIK enhanced colonization, indicating that this host protein acts as a susceptibility factor. Moreover, VIK overexpression specifically attenuated ICD, indicating that it is a negative regulator of immunity. The abilities of Pi17316 to enhance P. infestans colonization or suppress ICD were compromised significantly in NbVIK-silenced plants, demonstrating that the effector activity of Pi17316 is mediated by this MAP3K. Thus, StVIK is exploited by P. infestans as a susceptibility factor to promote late blight disease. PMID- 29588336 TI - Measurement of Gross Photosynthesis, Respiration in the Light, and Mesophyll Conductance Using H218O Labeling. AB - A fundamental challenge in plant physiology is independently determining the rates of gross O2 production by photosynthesis and O2 consumption by respiration, photorespiration, and other processes. Previous studies on isolated chloroplasts or leaves have separately constrained net and gross O2 production (NOP and GOP, respectively) by labeling ambient O2 with 18O while leaf water was unlabeled. Here, we describe a method to accurately measure GOP and NOP of whole detached leaves in a cuvette as a routine gas-exchange measurement. The petiole is immersed in water enriched to a delta18O of ~9,0000/00, and leaf water is labeled through the transpiration stream. Photosynthesis transfers 18O from H2O to O2 GOP is calculated from the increase in delta18O of O2 as air passes through the cuvette. NOP is determined from the increase in O2/N2 Both terms are measured by isotope ratio mass spectrometry. CO2 assimilation and other standard gas-exchange parameters also were measured. Reproducible measurements are made on a single leaf for more than 15 h. We used this method to measure the light response curve of NOP and GOP in French bean (Phaseolus vulgaris) at 21% and 2% O2 We then used these data to examine the O2/CO2 ratio of net photosynthesis, the light response curve of mesophyll conductance, and the apparent inhibition of respiration in the light (Kok effect) at both oxygen levels. The results are discussed in the context of evaluating the technique as a tool to study and understand leaf physiological traits. PMID- 29588337 TI - Psychosocial Effects of Parent-Child Book Reading Interventions: A Meta-analysis. AB - CONTEXT: Parent-child book reading (PCBR) is effective at improving young children's language, literacy, brain, and cognitive development. The psychosocial effects of PCBR interventions are unclear. OBJECTIVE: To systematically review and synthesize the effects of PCBR interventions on psychosocial functioning of children and parents. DATA SOURCES: We searched ERIC, PsycINFO, Medline, Embase, PubMed, Applied Social Sciences Index and Abstracts, Social Services Abstracts, Sociological Abstracts, Family and Society Studies Worldwide, and Social Work Abstracts. We hand searched references of previous literature reviews. STUDY SELECTION: Randomized controlled trials. DATA EXTRACTION: By using a standardized coding scheme, data were extracted regarding sample, intervention, and study characteristics. RESULTS: We included 19 interventions (3264 families). PCBR interventions improved the psychosocial functioning of children and parents compared with controls (standardized mean difference: 0.185; 95% confidence interval: 0.077 to 0.293). The assumption of homogeneity was rejected (Q = 40.010; P < .01). Two moderator variables contributed to between-group variance: method of data collection (observation less than interview; Qb = 7.497; P < .01) and rater (reported by others less than self-reported; Qb = 21.368; P < .01). There was no significant difference between effects of PCBR interventions on psychosocial outcomes of parents or children (Qb = 0.376; P = .540). LIMITATIONS: The ratio of moderating variables to the included studies limited interpretation of the findings. CONCLUSIONS: PCBR interventions are positively and significantly beneficial to the psychosocial functioning of both children and parents.

AB - Selexipag [2-{4-[(5,6-diphenylpyrazin-2-yl)(isopropyl)amino]butoxy}-N (methylsulfonyl)acetamide] is a selective nonprostanoid prostacyclin (PGI2) receptor (IP receptor) agonist that is approved for the treatment of pulmonary arterial hypertension (PAH). In contrast to selexipag, PGI2 analogs used in the clinic are nonselective agonists at prostanoid receptors and can also activate contractile prostaglandin E receptor 3 (EP3) receptors. Leg pain is a common side effect in patients receiving treatment with PGI2 analogs and peripheral vasoconstriction can be responsible for side effects related to muscular ischemia. This study tested the hypothesis that PGI2 analogs could cause paradoxical vasoconstriction of the femoral artery via EP3 receptor activation but that only vasorelaxation would be observed in response to selexipag and its active metabolite ACT-333679 [{4-[(5,6-diphenylpyrazin-2 yl)(isopropyl)amino]butoxy}acetic acid]. Selexipag and ACT-333679 relaxed rings of the isolated rat femoral artery contracted with either prostaglandin F2alpha (PGF2alpha ) or the alpha1 adrenoceptor (alpha1AR) agonist phenylephrine. ACT 333679 also inhibited contraction of the femoral artery to sympathetic nerve stimulation. In contrast, PGI2 analogs (iloprost, beraprost, and treprostinil) caused additional contraction of arterial rings precontracted with phenylephrine, which was reverted to relaxation by antagonism of EP3 receptors. Treprostinil augmented contraction of the femoral artery to sympathetic nerve stimulation in an EP3 receptor-dependent manner. Mechanistically, concomitant EP3 and alpha1AR receptor activation synergistically constricted femoral arteries. It is concluded that selexipag and ACT-333679 are vasorelaxants of the rat femoral artery and, unlike PGI2 analogs, do not cause paradoxical vasoconstriction via activation of EP3 receptors. EP3 receptor-mediated vasoconstriction may contribute to the well documented peripheral muscle pain reported in patients with PAH receiving PGI2 analogs. Leg pain may be less in patients treated with selexipag. PMID- 29588340 TI - XZ-1 regulates cell apoptosis of gastric epithelial dysplasia via NF kappaB/p53/Ki67 signaling pathway. AB - We aimed to determine the effect of 'Xiaozeng No. 1' (XZ-1) on cellular apoptosis changes of gastric epithelial dysplasia (GED) and to explore the underlying mechanism. Specimens taken from the pyloric area of the stomachs from rats in each group were subjected to Hematoxylin and Eosin (H&E) staining for pathological examination, TUNEL staining for apoptosis detection, and Western blot analysis for apoptosis-related proteins. The results showed that XZ-1 decreased GED incidence and enhanced gastric epithelial apoptosis. Furthermore, XZ-1 up-regulated the proapoptotic proteins including cleaved caspases (cysteine dependent aspartate-specific protease) (-3, -8, and -9), Fas, Bax, and Bid, and facilitated the release of cytochrome c from mitochondria to the cytoplasm. Interestingly, XZ-1 enhanced protein expression of NF-kappaB p65, Ki67, and p53. Moreover, inhibition of NF-kappaB pathway suppressed the XZ-induced p53 expression, whereas inhibition of NF-kappaB or p53 pathway suppressed the XZ induced Ki67. More importantly, inhibition of NF-kappaB or p53 pathway attenuated the XZ-1-mediated induction of gastric epithelial apoptosis and decline of GED incidence. Collectively, our results demonstrated that XZ-1, almost equivalent effect exerted by the positive control Retin-A, dramatically decreased GED incidence and enhanced gastric epithelial apoptosis. Meanwhile, XZ-1 activated the NF-kappaB/p53/Ki67-apoptosis signaling pathway, which might be one of the mechanisms whereby XZ-1 reversed GED. PMID- 29588341 TI - Homeostasis model assessment of insulin resistance in relation to the poor functional outcomes in nondiabetic patients with ischemic stroke. AB - Whether insulin resistance (IR) predicts worse functional outcome in ischemic stroke is still a matter of debate. The aim of the present study is to determine the association between IR and risk of poor outcome in 173 Chinese nondiabetic patients with acute ischemic stroke. This is a prospective, population-based cohort study. Insulin sensitivity, expressed by the homeostasis model assessment (HOMA) of insulin sensitivity (HOMA index = (fasting insulin * fasting glucose)/22.5). IR was defined by HOMA-IR index in the top quartile (Q4). Functional impairment was evaluated at discharge using the modified Rankin scale (mRS). The median (interquartile range) HOMA-IR was 2.14 (1.17-2.83), and Q4 was at least 2.83. There was a significantly positive correlation between HOMA-IR and National Institutes of Health Stroke Scale (r = 0.408; P<0.001). In multivariate analyses, patients in IR group were associated with a higher risk of poor functional outcome (odds ratio (OR) = 3.23; 95% confidence interval (CI) = 1.75 5.08; P=0.001). In multivariate models comparing the third and fourth quartiles against the first quartile of the HOMA-IR, levels of HOMA-IR were associated with poor outcome, and the adjusted risk of poor outcome increased by 207% (OR = 3.05 (95% CI 1.70-4.89), P=0.006) and 429% (5.29 (3.05-9.80), P<0.001). In a receiver operating characteristic curve (ROC) analysis of poor outcome, the area under the curve (AUC) increased from 0.80 to 0.84 (95% CI: 0.79-0.88) by adding HOMA-IR to clinical examination variables (P=0.02). High HOMA-IR index is associated with a poor functional outcome in nondiabetic patients with acute ischemic stroke. PMID- 29588342 TI - Matrix-bound AGEs enhance TGFbeta2-mediated mesenchymal transition of lens epithelial cells via the noncanonical pathway: implications for secondary cataract formation. AB - Advanced glycation end products (AGEs) are post-translational modifications formed from the reaction of reactive carbonyl compounds with amino groups in proteins. Our laboratory has previously shown that AGEs in extracellular matrix (ECM) proteins promote TGFbeta2 (transforming growth factor-beta 2)-mediated epithelial-to-mesenchymal transition (EMT) of lens epithelial cells (LECs), which could play a role in fibrosis associated with posterior capsule opacification. We have also shown that alphaB-crystallin plays an important role in TGFbeta2 mediated EMT of LECs. Here, we investigated the signaling mechanisms by which ECM AGEs enhance TGFbeta2-mediated EMT in LECs. We found that in LECs cultured on AGE modified basement protein extract (AGE-BME), TGFbeta2 treatment up-regulated the mesenchymal markers alpha-SMA (alpha-smooth muscle actin) and alphaB-crystallin and down-regulated the epithelial marker E-cadherin more than LECs cultured on unmodified BME and treated with TGFbeta2. Using a Multiplex Assay, we found that AGE-BME significantly up-regulated the noncanonical pathway by promoting phosphorylation of ERK (extracellular signal-regulated kinases), AKT, and p38 MAPK (mitogen-activated protein kinases) during TGFbeta2-mediated EMT. This EMT response was strongly suppressed by inhibition of AKT and p38 MAPK phosphorylation. The AKT inhibitor LY294002 also suppressed TGFbeta2-induced up regulation of nuclear Snail and reduced phosphorylation of GSK3beta. Inhibition of Snail expression suppressed TGFbeta2-mediated alpha-SMA expression. alphaB Crystallin was up-regulated in an AKT-dependent manner during AGE-BME/TGFbeta2 mediated EMT in LECs. The absence of alphaB-crystallin in LECs suppressed TGFbeta2-induced GSK3beta phosphorylation, resulting in lower Snail levels. Taken together, these results show that ECM-AGEs enhance the TGFbeta2-mediated EMT response through activation of the AKT/Snail pathway, in which alphaB-crystallin plays an important role as a linker between the TGFbeta2 and AGE-mediated signaling pathways. PMID- 29588343 TI - Ionotropic and Metabotropic Mechanisms of Allosteric Modulation of alpha7 Nicotinic Receptor Intracellular Calcium. AB - The pharmacological targeting of the alpha7 nicotinic acetylcholine receptor (alpha7) is a promising strategy in the development of new drugs for neurologic diseases. Because alpha7 receptors regulate cellular calcium, we investigated how the prototypical type II-positive allosteric modulator PNU120596 affects alpha7 mediated calcium signaling. Live imaging experiments show that PNU120596 augments ryanodine receptor-driven calcium-induced calcium release (CICR), inositol induced calcium release (IICR), and phospholipase C activation by the alpha7 receptor. Both influx of calcium through the alpha7 nicotinic acetylcholine receptor (nAChR) channel as well as the binding of intracellular G proteins were involved in the effect of PNU120596 on intracellular calcium. This is evidenced by the findings that chelation of extracellular calcium, expression of alpha7D44A or alpha7345-348A mutant subunits, or blockade of calcium store release compromised the ability of PNU120596 to increase intracellular calcium transients generated by alpha7 ligand activation. Spatiotemporal stochastic modeling of calcium transient responses corroborates these results and indicates that alpha7 receptor activation enables calcium microdomains locally and to lesser extent in the distant cytosol. From the model, allosteric modulation of the receptor activates CICR locally via ryanodine receptors and augments IICR through enhanced calcium influx due to prolonged alpha7 nAChR opening. These findings provide a new mechanistic framework for understanding the effect of alpha7 receptor allosteric modulation on both local and global calcium dynamics.

AB - OBJECTIVES: To determine the frequency of sexual history taking and the associated characteristics of hospitalized adolescents in the pediatric hospitalist service. METHODS: A retrospective chart review of adolescents 14 to 18 years old who were admitted to the pediatric hospitalist service at an urban, academic children's hospital in the Northeast from 2013 to 2015 was conducted. Repeat admissions, admissions to specialty services, and charts that noted impairment because of psychosis, cognitive delay, or illness severity were excluded. For charts that met the criteria, the admission history and physical was carefully reviewed for a notation of sexual history. For those with documentation, sexual activity status and a risk level assessment were recorded. Patient demographics and admission characteristics were extracted. chi2 tests and logistic regression were used to examine differences between those with sexual history and those without. RESULTS: A total of 752 charts met the criteria for inclusion. The majority of adolescents were girls (n = 506; 67.3%); the mean age was 15.7 years (SD = 1.2). Girls had 2.99 (95% confidence interval [CI] 2.18 4.11) higher odds of documentation than boys, and older adolescents had 1.41 (95% CI 1.03-1.91) higher odds than younger adolescents. Documentation did not differ significantly on the basis of admission type (medical or psychiatric), admission time, patient race and/or ethnicity, or provider gender. Among those with a documented sexual history, risk-level details were often omitted. CONCLUSIONS: Sexual history taking does not occur universally for hospitalized adolescents. Girls were screened more often than boys despite similar rates of sexual activity. The inpatient admission may be a missed opportunity for harm-reduction counseling and adherence to sexually transmitted infection testing guidelines. PMID- 29588346 TI - Microbial symbionts regulate the primary Ig repertoire. AB - The ability of immunoglobulin (Ig) to recognize pathogens is critical for optimal immune fitness. Early events that shape preimmune Ig repertoires, expressed on IgM+ IgD+ B cells as B cell receptors (BCRs), are poorly defined. Here, we studied germ-free mice and conventionalized littermates to explore the hypothesis that symbiotic microbes help shape the preimmune Ig repertoire. Ig-binding assays showed that exposure to conventional microbial symbionts enriched frequencies of antibacterial IgM+ IgD+ B cells in intestine and spleen. This enrichment affected follicular B cells, involving a diverse set of Ig-variable region gene segments, and was T cell-independent. Functionally, enrichment of microbe reactivity primed basal levels of small intestinal T cell-independent, symbiont-reactive IgA and enhanced systemic IgG responses to bacterial immunization. These results demonstrate that microbial symbionts influence host immunity by enriching frequencies of antibacterial specificities within preimmune B cell repertoires and that this may have consequences for mucosal and systemic immunity. PMID- 29588347 TI - Termination of T cell priming relies on a phase of unresponsiveness promoting disengagement from APCs and T cell division. AB - T cells are primed in secondary lymphoid organs by establishing stable interactions with antigen-presenting cells (APCs). However, the cellular mechanisms underlying the termination of T cell priming and the initiation of clonal expansion remain largely unknown. Using intravital imaging, we observed that T cells typically divide without being associated to APCs. Supporting these findings, we demonstrate that recently activated T cells have an intrinsic defect in establishing stable contacts with APCs, a feature that was reflected by a blunted capacity to stop upon T cell receptor (TCR) engagement. T cell unresponsiveness was caused, in part, by a general block in extracellular calcium entry. Forcing TCR signals in activated T cells antagonized cell division, suggesting that T cell hyporesponsiveness acts as a safeguard mechanism against signals detrimental to mitosis. We propose that transient unresponsiveness represents an essential phase of T cell priming that promotes T cell disengagement from APCs and favors effective clonal expansion. PMID- 29588348 TI - Intratumoral CpG-B Promotes Antitumoral Neutrophil, cDC, and T-cell Cooperation without Reprograming Tolerogenic pDC. AB - Cancer immunotherapies utilize distinct mechanisms to harness the power of the immune system to eradicate cancer cells. Therapeutic vaccines, aimed at inducing active immune responses against an existing cancer, are highly dependent on the immunological microenvironment, where many immune cell types display high levels of plasticity and, depending on the context, promote very different immunologic outcomes. Among them, plasmacytoid dendritic cells (pDC), known to be highly immunogenic upon inflammation, are maintained in a tolerogenic state by the tumor microenvironment. Here, we report that intratumoral (i.t.) injection of established solid tumors with CpG oligonucleotides-B (CpG-B) inhibits tumor growth. Interestingly, control of tumor growth was independent of tumor associated pDC, which remained refractory to CpG-B stimulation and whose depletion did not alter the efficacy of the treatment. Instead, tumor growth inhibition subsequent to i.t. CpG-B injection depended on the recruitment of neutrophils into the milieu, resulting in the activation of conventional dendritic cells, subsequent increased antitumor T-cell priming in draining lymph nodes, and enhanced effector T-cell infiltration in the tumor microenvironment. These results reinforce the concept that i.t. delivery of TLR9 agonists alters the tumor microenvironment by improving the antitumor activity of both innate and adaptive immune cells.Significance: Intratumoral delivery of CpG-B disrupts the tolerogenic tumor microenvironment and inhibits tumor growth.

AB - Although oncogenic activation of NFkappaB has been identified in various tumors, the NFkappaB-activating kinases (inhibitor of NFkappaB kinases, IKK) responsible for this are elusive. In this study, we determined the role of IKKalpha and IKKbeta in KRAS-mutant lung adenocarcinomas induced by the carcinogen urethane and by respiratory epithelial expression of oncogenic KRASG12D Using NFkappaB reporter mice and conditional deletions of IKKalpha and IKKbeta, we identified two distinct early and late activation phases of NFkappaB during chemical and genetic lung adenocarcinoma development, which were characterized by nuclear translocation of RelB, IkappaBbeta, and IKKalpha in tumor-initiated cells. IKKalpha was a cardinal tumor promoter in chemical and genetic KRAS-mutant lung adenocarcinoma, and respiratory epithelial IKKalpha-deficient mice were markedly protected from the disease. IKKalpha specifically cooperated with mutant KRAS for tumor induction in a cell-autonomous fashion, providing mutant cells with a survival advantage in vitro and in vivo IKKalpha was highly expressed in human lung adenocarcinoma, and a heat shock protein 90 inhibitor that blocks IKK function delivered superior effects against KRAS-mutant lung adenocarcinoma compared with a specific IKKbeta inhibitor. These results demonstrate an actionable requirement for IKKalpha in KRAS-mutant lung adenocarcinoma, marking the kinase as a therapeutic target against this disease.Significance: These findings report a novel requirement for IKKalpha in mutant KRAS lung tumor formation, with potential therapeutic applications.

AB - Somatic copy number variations (CNV) may drive cancer progression through both coding and noncoding transcripts. However, noncoding transcripts resulting from CNV are largely unknown, especially for circular RNAs. By integrating bioinformatics analyses of alerted circRNAs and focal CNV in lung adenocarcinoma, we identify a proto-oncogenic circular RNA (circPRKCI) from the 3q26.2 amplicon, one of the most frequent genomic aberrations in multiple cancers. circPRKCI was overexpressed in lung adenocarcinoma tissues, in part due to amplification of the 3q26.2 locus, and promoted proliferation and tumorigenesis of lung adenocarcinoma. circPRKCI functioned as a sponge for both miR-545 and miR-589 and abrogated their suppression of the protumorigenic transcription factor E2F7 Intratumor injection of cholesterol-conjugated siRNA specifically targeting circPRKCI inhibited tumor growth in a patient-derived lung adenocarcinoma xenograft model. In summary, circPRKCI is crucial for tumorigenesis and may serve as a potential therapeutic target in patients with lung adenocarcinoma.Significance: These findings reveal high expression of the circular RNA circPRKCI drives lung adenocarcinoma tumorigenesis.

AB - Long noncoding RNAs (lncRNA) have been associated with various types of cancer; however, the precise role of many lncRNAs in tumorigenesis remains elusive. Here we demonstrate that the cytosolic lncRNA P53RRA is downregulated in cancers and functions as a tumor suppressor by inhibiting cancer progression. Chromatin remodeling proteins LSH and Cfp1 silenced or increased P53RRA expression, respectively. P53RRA bound Ras GTPase-activating protein-binding protein 1 (G3BP1) using nucleotides 1 and 871 of P53RRA and the RRM interaction domain of G3BP1 (aa 177-466). The cytosolic P53RRA-G3BP1 interaction displaced p53 from a G3BP1 complex, resulting in greater p53 retention in the nucleus, which led to cell-cycle arrest, apoptosis, and ferroptosis. P53RRA promoted ferroptosis and apoptosis by affecting transcription of several metabolic genes. Low P53RRA expression significantly correlated with poor survival in patients with breast and lung cancers harboring wild-type p53. These data show that lncRNAs can directly interact with the functional domain of signaling proteins in the cytoplasm, thus regulating p53 modulators to suppress cancer progression.Significance: A cytosolic lncRNA functions as a tumor suppressor by activating the p53 pathway.

AB - BACKGROUND: Electronic nicotine delivery systems (ENDS) are battery-operated devices used to inhale vaporized or aerosolized nicotine. There is increasing research uncovering negative health effects of these devices. Less is known about the social and behavioral aspects among college students. METHODS: This cross sectional study was conducted at a mid-sized private university in Florida. The survey was sent via e-mail to the student body of undergraduates. A final sample size of 989 students was analyzed to understand demographic differences between users and nonusers, initiation factors, and influencers, as well as multiple product behaviors. RESULTS: Approximately 51.4% (n = 508) of participants reported ever using an ENDS and other tobacco consumption. Males were significantly more likely to be users of ENDS. Polytobacco use, or the use of multiple tobacco products, was also more common among participants who have tried ENDS (P < .001). Perceptions of harm of both the primary and secondary vapor were considered to be less than that of conventional cigarettes. Peers were the primary influencer for initial use. A 4-class latent variable model differentiated between usage patterns characterized as abstainers (70%), hookah users only (14%), ENDS only (11%), and polytobacco users (4%). CONCLUSIONS: ENDS are not commonly used as a quit tool among college students, but rather as a secondary source of nicotine, most commonly in current smokers.

AB - We report our clinical experience treating a 2-month-old infant with congenital diaphragmatic hernia who experienced prolonged bacteremia with Burkholderia cepacia complex (Bcc) despite conventional antibiotic therapy and appropriate source control measures. The infection resolved after initiation of ceftazidime avibactam. Whole-genome sequencing revealed that the isolate most closely resembled B. contaminans and identified the mechanism of resistance that likely contributed to clinical cure with this agent. Ceftazidime-avibactam should be considered salvage therapy for Bcc infections if other treatment options have been exhausted. PMID- 29588359 TI - Antiphospholipid syndrome presenting as acute mesenteric venous thrombosis involving a variant inferior mesenteric vein and successful treatment with rivaroxaban. AB - Acute mesenteric venous thrombosis (MVT) is the rarest cause of acute mesenteric ischaemia, so thrombosis of a variant inferior mesenteric vein (IMV) is especially uncommon in the setting of antiphospholipid syndrome (APS). Here, we present such a case of seronegative APS initially manifesting as an anomalous IMV thrombosis in a 76-year-old woman. Although guidelines support anticoagulation with vitamin K antagonists in these patients, we anticoagulated with rivaroxaban (a direct oral anticoagulant (DOAC)) due to patient preference, which resulted in complete clinical and endoscopic resolution. IMV thrombosis is a rare form of MVT, only two case reports describe successful anticoagulation with DOACs in the setting of MVT and none report APS as an underlying aetiology. Therefore, this case provides the opportunity to review the pathophysiology of MVT, APS and their medical management including current trends in anticoagulation. PMID- 29588360 TI - taxMaps: comprehensive and highly accurate taxonomic classification of short-read data in reasonable time. AB - High-throughput sequencing is a revolutionary technology for the analysis of metagenomic samples. However, querying large volumes of reads against comprehensive DNA/RNA databases in a sensitive manner can be compute-intensive. Here, we present taxMaps, a highly efficient, sensitive, and fully scalable taxonomic classification tool. Using a combination of simulated and real metagenomics data sets, we demonstrate that taxMaps is more sensitive and more precise than widely used taxonomic classifiers and is capable of delivering classification accuracy comparable to that of BLASTN, but at up to three orders of magnitude less computational cost. PMID- 29588361 TI - Sequential regulatory activity prediction across chromosomes with convolutional neural networks. AB - Models for predicting phenotypic outcomes from genotypes have important applications to understanding genomic function and improving human health. Here, we develop a machine-learning system to predict cell-type-specific epigenetic and transcriptional profiles in large mammalian genomes from DNA sequence alone. By use of convolutional neural networks, this system identifies promoters and distal regulatory elements and synthesizes their content to make effective gene expression predictions. We show that model predictions for the influence of genomic variants on gene expression align well to causal variants underlying eQTLs in human populations and can be useful for generating mechanistic hypotheses to enable fine mapping of disease loci. PMID- 29588362 TI - Double insertion of transposable elements provides a substrate for the evolution of satellite DNA. AB - Eukaryotic genomes are replete with repeated sequences in the form of transposable elements (TEs) dispersed across the genome or as satellite arrays, large stretches of tandemly repeated sequences. Many satellites clearly originated as TEs, but it is unclear how mobile genetic parasites can transform into megabase-sized tandem arrays. Comprehensive population genomic sampling is needed to determine the frequency and generative mechanisms of tandem TEs, at all stages from their initial formation to their subsequent expansion and maintenance as satellites. The best available population resources, short-read DNA sequences, are often considered to be of limited utility for analyzing repetitive DNA due to the challenge of mapping individual repeats to unique genomic locations. Here we develop a new pipeline called ConTExt that demonstrates that paired-end Illumina data can be successfully leveraged to identify a wide range of structural variation within repetitive sequence, including tandem elements. By analyzing 85 genomes from five populations of Drosophila melanogaster, we discover that TEs commonly form tandem dimers. Our results further suggest that insertion site preference is the major mechanism by which dimers arise and that, consequently, dimers form rapidly during periods of active transposition. This abundance of TE dimers has the potential to provide source material for future expansion into satellite arrays, and we discover one such copy number expansion of the DNA transposon hobo to approximately 16 tandem copies in a single line. The very process that defines TEs-transposition-thus regularly generates sequences from which new satellites can arise. PMID- 29588363 TI - Effects of hypo-O-GlcNAcylation on Drosophila development. AB - Post-translational modification of serine/threonine residues in nucleocytoplasmic proteins with GlcNAc (O-GlcNAcylation) is an essential regulatory mechanism in many cellular processes. In Drosophila, null mutants of the Polycomb gene O GlcNAc transferase (OGT; also known as super sex combs (sxc)) display homeotic phenotypes. To dissect the requirement for O-GlcNAc signaling in Drosophila development, we used CRISPR/Cas9 gene editing to generate rationally designed sxc catalytically hypomorphic or null point mutants. Of the fertile males derived from embryos injected with the CRISPR/Cas9 reagents, 25% produced progeny carrying precise point mutations with no detectable off-target effects. One of these mutants, the catalytically inactive sxcK872M , was recessive lethal, whereas a second mutant, the hypomorphic sxcH537A , was homozygous viable. We observed that reduced total protein O-GlcNAcylation in the sxcH537A mutant is associated with a wing vein phenotype and temperature-dependent lethality. Genetic interaction between sxcH537A and a null allele of Drosophila host cell factor (dHcf), encoding an extensively O-GlcNAcylated transcriptional coactivator, resulted in abnormal scutellar bristle numbers. A similar phenotype was also observed in sxcH537A flies lacking a copy of skuld (skd), a Mediator complex gene known to affect scutellar bristle formation. Interestingly, this phenotype was independent of OGT Polycomb function or dHcf downstream targets. In conclusion, the generation of the endogenous OGT hypomorphic mutant sxcH537A enabled us to identify pleiotropic effects of globally reduced protein O-GlcNAc during Drosophila development. The mutants generated and phenotypes observed in this study provide a platform for discovery of OGT substrates that are critical for Drosophila development. PMID- 29588364 TI - Spatially dependent alkyl quinolone signaling responses to antibiotics in Pseudomonas aeruginosa swarms. AB - There is a general lack of understanding about how communities of bacteria respond to exogenous toxins such as antibiotics. Most of our understanding of community-level stress responses comes from the study of stationary biofilm communities. Although several community behaviors and production of specific biomolecules affecting biofilm development and associated behavior have been described for Pseudomonas aeruginosa and other bacteria, we have little appreciation for the production and dispersal of secreted metabolites within the 2D and 3D spaces they occupy as they colonize, spread, and grow on surfaces. Here we specifically studied the phenotypic responses and spatial variability of alkyl quinolones, including the Pseudomonas quinolone signal (PQS) and members of the alkyl hydroxyquinoline (AQNO) subclass, in P. aeruginosa plate-assay swarming communities. We found that PQS production was not a universal signaling response to antibiotics, as tobramycin elicited an alkyl quinolone response, whereas carbenicillin did not. We also found that PQS and AQNO profiles in response to tobramycin were markedly distinct and influenced these swarms on different spatial scales. At some tobramycin exposures, P. aeruginosa swarms produced alkyl quinolones in the range of 150 MUm PQS and 400 MUm AQNO that accumulated as aggregates. Our collective findings show that the distribution of alkyl quinolones can vary by several orders of magnitude within the same swarming community. More notably, our results suggest that multiple intercellular signals acting on different spatial scales can be triggered by one common cue. PMID- 29588365 TI - A three-way inter-molecular network accounts for the CaValpha2delta1-induced functional modulation of the pore-forming CaV1.2 subunit. AB - L-type CaV1.2 channels are essential for the excitation-contraction coupling in cardiomyocytes and are hetero-oligomers of a pore-forming CaValpha1C assembled with CaVbeta and CaValpha2delta1 subunits. A direct interaction between CaValpha2delta1 and Asp-181 in the first extracellular loop of CaValpha1 reproduces the native properties of the channel. A 3D model of the von Willebrand factor type A (VWA) domain of CaValpha2delta1 complexed with the voltage sensor domain of CaValpha1C suggests that Ser-261 and Ser-263 residues in the metal ion dependent adhesion site (MIDAS) motif are determinant in this interaction, but this hypothesis is untested. Here, coimmunoprecipitation assays and patch-clamp experiments of single-substitution variants revealed that CaValpha2delta1 Asp-259 and Ser-261 are the two most important residues in regard to protein interactions and modulation of CaV1.2 currents. In contrast, mutating the side chains of CaValpha2delta1 Ser-263, Thr-331, and Asp-363 with alanine did not completely prevent channel function. Molecular dynamics simulations indicated that the carboxylate side chain of CaValpha2delta1 Asp-259 coordinates the divalent cation that is further stabilized by the oxygen atoms from the hydroxyl side chain of CaValpha2delta1 Ser-261 and the carboxylate group of CaValpha1C Asp-181. In return, the hydrogen atoms contributed by the side chain of Ser-261 and the main chain of Ser-263 bonded the oxygen atoms of CaV1.2 Asp-181. We propose that CaValpha2delta1 Asp-259 promotes Ca2+ binding necessary to produce the conformation of the VWA domain that locks CaValpha2delta1 Ser-261 and Ser-263 within atomic distance of CaValpha1C Asp-181. This three-way network appears to account for the CaValpha2delta1-induced modulation of CaV1.2 currents. PMID- 29588366 TI - The long noncoding RNA lncZic2 drives the self-renewal of liver tumor-initiating cells via the protein kinase C substrates MARCKS and MARCKSL1. AB - Liver tumor-initiating cells (TICs) form small subsets of cells in hepatocellular tumors and account for tumorigenesis, metastasis, recurrence, and drug resistance. Recently, we found that the transcription factor Zic family member 2 (ZIC2) is highly expressed in liver TICs and required for their self-renewal. However, the molecular mechanisms underlying self-renewal of liver TICs remain unclear. Here, using expression profiling and CRISPR-interference assays with clinical samples of human liver cancers, we identified a long noncoding RNA (lncRNA), lncZic2, that is located near the ZIC2 locus and was highly expressed in liver cancer and liver TICs. We found that lncZic2 is required for the self renewal of liver TICs in a ZIC2-independent manner. lncZic2 drove the expression of myristoylated alanine-rich protein kinase C substrate (MARCKS) and MARCKS-like 1 (MARCKSL1), whose expression levels were increased during liver tumorigenesis and liver TIC self-renewal. Mechanistically, lncZic2 interacted with BRM/SWI2 related gene 1 (BRG1) and recruited this transcriptional regulator to the promoters of the MARCKS and MARCKSL1 gene, which activated expression of these genes. Moreover, we noted that depletion of lncZic2 and BRG1 decreases MARCKS and MARCKSL1 expression and diminishes liver TIC levels. In conclusion, lncZic2 is required for the self-renewal of liver TICs by up-regulating MARCKS and MARCKSL1 gene expression via the transcription factor BRG1. Our findings suggest that the lncZic2-BRG1-MARCKS/MARCKSL1 signaling cascade might be a potential target for eliminating liver TICs in the management of liver cancer. PMID- 29588367 TI - A cassette of basic amino acids in histone H2B regulates nucleosome dynamics and access to DNA damage. AB - Nucleosome dynamics, such as spontaneous DNA unwrapping, are postulated to have a critical role in regulating the access of DNA repair machinery to DNA lesions within nucleosomes. However, the specific histone domains that regulate nucleosome dynamics and the impact of such changes in intrinsic nucleosome dynamics on DNA repair are not well understood. Previous studies identified a highly conserved region in the N-terminal tail of histone H2B known as the histone H2Brepression (or HBR) domain, which has a significant influence on gene expression, chromatin assembly, and DNA damage formation and repair. However, the molecular mechanism(s) that may account for these observations are limited. In this study, we characterized the stability and dynamics of DeltaHBR mutant nucleosome core particles (NCPs) in vitro by restriction enzyme accessibility (REA), FRET, and temperature-induced sliding of histone octamers. Our results indicate that DeltaHBR-NCPs are more dynamic, with a larger steady-state fraction of the NCP population occupying the unwrapped state than for WT-NCPs. Additionally, DeltaHBR-histone octamers are more susceptible to temperature induced sliding on DNA than WT histone octamers. Furthermore, we show that the activity of base excision repair enzymes at uracil lesions and single nucleotide gaps is enhanced in a site-specific manner in DeltaHBR-NCPs. This enhanced activity correlates well with regions exhibiting increased DNA unwrapping. Finally, removal of the HBR domain is not sufficient to completely alleviate the structural constraints imposed by histone octamers on the activity of base excision repair enzymes.

AB - Circadian locomotor output cycles kaput (CLOCK) is a transcription factor that activates transcription of clock-controlled genes by heterodimerizing with BMAL1 and binding to E-box elements on DNA. Although several phosphorylation sites on CLOCK have already been identified, this study characterizes a novel phosphorylation site at serine 845 (Ser-836 in humans). Here, we show that CLOCK is a novel AKT substrate in vitro and in cells, and this phosphorylation site is a negative regulator of CLOCK nuclear localization by acting as a binding site for 14-3-3 proteins. To examine the role of CLOCK phosphorylation in vivo, ClockS845A knockin mice were generated using CRISPR/Cas9 technology. ClockS845A mice are essentially normal with normal central circadian rhythms and hemodynamics. However, examination of core circadian gene expression from peripheral tissues demonstrated that ClockS845A mice have diminished expression of Per2, Reverba, Dbp, and Npas2 in skeletal muscle and Per2, Reverba, Dbp, Per1, Rora, and Npas2 in the liver during the circadian cycle. The reduction in Dbp levels is associated with reduced H3K9ac at E-boxes where CLOCK binds despite no change in total CLOCK levels. Thus, CLOCK phosphorylation by AKT on Ser-845 regulates its nuclear translocation and the expression levels of certain core circadian genes in insulin-sensitive tissues.

AB - Membrane biology seeks to understand how lipids and proteins within bilayers assemble into large structures such as organelles and the plasma membranes. Historically, lipids were thought to merely provide structural support for bilayer formation and membrane protein function. Research has now revealed that phospholipid metabolism regulates nearly all cellular processes. Sophisticated techniques helped identify >10,000 lipid species suggesting that lipids support many biological processes. Here, we highlight the synthesis of the most abundant glycerophospholipid classes and their distribution in organelles. We review vesicular and nonvesicular transport pathways shuttling lipids between organelles and discuss lipid regulators of membrane trafficking and second messengers in eukaryotic cells. PMID- 29588370 TI - Intrinsic properties and plasma membrane trafficking route of Src family kinase SH4 domains sensitive to retargeting by HIV-1 Nef. AB - The HIV type 1 pathogenicity factor Nef enhances viral replication by modulating multiple host cell pathways, including tuning the activation state of infected CD4 T lymphocytes to optimize virus spread. For this, Nef inhibits anterograde transport of the Src family kinase (SFK) Lck toward the plasma membrane (PM). This leads to retargeting of the kinase to the trans-Golgi network, whereas the intracellular transport of a related SFK, Fyn, is unaffected by Nef. The 18-amino acid Src homology 4 (SH4) domain membrane anchor of Lck is necessary and sufficient for Nef-mediated retargeting, but other details of this process are not known. The goal of this study was therefore to identify characteristics of SH4 domains responsive to Nef and the transport machinery used. Screening a panel of SFK SH4 domains revealed two groups that were sensitive or insensitive for trans-Golgi network retargeting by Nef as well as the importance of the amino acid at position 8 for determining Nef sensitivity. Anterograde transport of Nef sensitive domains was characterized by slower delivery to the PM and initial targeting to Golgi membranes, where transport was arrested in the presence of Nef. For Nef-sensitive SH4 domains, ectopic expression of the lipoprotein binding chaperone Unc119a or the GTPase Arl3 or reduction of their endogenous expression phenocopied the effect of Nef. Together, these results suggest that, analogous to K-Ras, Nef-sensitive SH4 domains are transported to the PM by a cycle of solubilization and membrane insertion and that intrinsic properties define SH4 domains as cargo of this Nef-sensitive lipoprotein binding chaperone-GTPase transport cycle. PMID- 29588373 TI - FOXO3a expression is associated with lymph node metastasis and poor disease-free survival in triple-negative breast cancer. AB - AIMS: Forkhead box O (FOXO) transcription factors, consisting of FOXO1, FOXO3a, FOXO4 and FOXO6, are involved in carcinogenesis and tumour progression. Recent studies have suggested that FOXOs act as tumour suppressors in a variety of human cancers. This study investigated the clinicopathological significance of FOXOs in triple-negative breast cancer (TNBC). METHODS: FOXO protein expressions were assessed by immunohistochemistry in 125 TNBC tissues. Correlations between FOXO protein expression and various clinicopathological parameters, including patients' survival, were investigated. MDA-MB-468 cell line was used for in vitro cell proliferation and migration assay. RESULTS: FOXO1 protein expression was not observed in all 125 TNBC tissues. FOXO4 and FOXO6 protein expressions were detected in 11 (8.8%) and 14 (11.2%) TNBC tissues, respectively. Loss of FOXO4 expression was significantly associated with high histological grade (P=0.014, chi2 test), and TNBCs with positive FOXO6 expression correlated with high grade (P=0.020, chi2 test). FOXO3a expression was detected in 40 (32%) TNBC cases and correlated with adverse clinicopathological features, such as lymph node metastasis (P=0.021, chi2 test), perineural invasion (P=0.013, chi2 test) and higher Ki-67 proliferation index (P=0.048, t-test). Additionally, FOXO3a expression was significantly associated with poor disease-free survival (P=0.015, log-rank test). In the in vitro study, siRNA-mediated FOXO3a knockdown in the MDA MB-468 cell line inhibited cell proliferation and migration. CONCLUSION: Among FOXO members, FOXO3a may have a potential role in promoting tumour cell migration and proliferation and may serve as a prognostic biomarker and a potential therapeutic target for TNBC. PMID- 29588372 TI - Prognostic value of Ki67 analysed by cytology or histology in primary breast cancer. AB - AIMS: The accuracy of biomarker assessment in breast pathology is vital for therapy decisions. The therapy predictive and prognostic biomarkers oestrogen receptor (ER), progesterone receptor, HER2 and Ki67 may act as surrogates to gene expression profiling of breast cancer. The aims of this study were to investigate the concordance of consecutive biomarker assessment by immunocytochemistry on preoperative fine-needle aspiration cytology versus immunohistochemistry (IHC) on the corresponding resected breast tumours. Further, to investigate the concordance with molecular subtype and correlation to stage and outcome. METHODS: Two retrospective cohorts comprising 385 breast tumours with clinicopathological data including gene expression-based subtype and up to 10-year overall survival data were evaluated. RESULTS: In both cohorts, we identified a substantial variation in Ki67 index between cytology and histology and a switch between low and high proliferation within the same tumour in 121/360 cases. ER evaluations were discordant in only 1.5% of the tumours. From cohort 2, gene expression data with PAM50 subtype were used to correlate surrogate subtypes. IHC-based surrogate classification could identify the correct molecular subtype in 60% and 64% of patients by cytology (n=63) and surgical resections (n=73), respectively. Furthermore, high Ki67 in surgical resections but not in cytology was associated with poor overall survival and higher probability for axillary lymph node metastasis. CONCLUSIONS: This study shows considerable differences in the prognostic value of Ki67 but not ER in breast cancer depending on the diagnostic method. Furthermore, our findings show that both methods are insufficient in predicting true molecular subtypes. PMID- 29588374 TI - Flow cytometric minimal residual disease assessment of peripheral blood in acute lymphoblastic leukaemia patients has potential for early detection of relapsed extramedullary disease. AB - OBJECTIVES: To evaluate peripheral blood (PB) for minimal residual disease (MRD) assessment in adults with acute lymphoblastic leukaemia (ALL). METHODS: We analysed 76 matched bone marrow (BM) aspirate and PB specimens independently for the presence of ALL MRD by six-colour flow cytometry (FC). RESULTS: The overall rate of BM MRD-positivity was 24% (18/76) and PB was also MRD-positive in 22% (4/18) of BM-positive cases. We identified two cases with evidence of leukaemic cells in PB at the time of the extramedullary relapse that were interpreted as MRD-negative in BM. CONCLUSIONS: The use of PB MRD as a non-invasive method for monitoring of systemic relapse may have added clinical and diagnostic value in patients with high risk of extramedullary disease. PMID- 29588375 TI - A novel homozygous frameshift mutation in the FUCA1 gene causes both severe and mild fucosidosis. AB - AIMS: Fucosidosis is a rare autosomal recessive lysosomal storage disorder caused by alpha-L-fucosidase deficiency as a result of FUCA1 gene mutations. Here, we studied clinical features and the molecular basis of fucosidosis in a family from Iran, including two probands and nine family members. METHODS: DNA sample of two probands were screened for gene defects using a next generation sequencing technique. The sequencing processes were performed on an Illumina Hiseq 4000 platform. Sequence reads were analysed using BWA-GATK. RESULTS: Next generation sequencing revealed a frameshift mutation caused by 2 bp deletion (c.837_838 delTG; p.Cys279) in the FUCA1 gene. The identified mutation was tested in all participants. Homozygous patients had almost all the complications associated with fucosidosis, while heterozygous carriers were unaffected. CONCLUSIONS: The variant c.837_838 delTG; p.Cys279 has not been reported previously and is predicted to be pathogenic due to a premature stop codon. PMID- 29588376 TI - TRRAP is a central regulator of human multiciliated cell formation. AB - The multiciliated cell (MCC) is an evolutionarily conserved cell type, which in vertebrates functions to promote directional fluid flow across epithelial tissues. In the conducting airway, MCCs are generated by basal stem/progenitor cells and act in concert with secretory cells to perform mucociliary clearance to expel pathogens from the lung. Studies in multiple systems, including Xenopus laevis epidermis, murine trachea, and zebrafish kidney, have uncovered a transcriptional network that regulates multiple steps of multiciliogenesis, ultimately leading to an MCC with hundreds of motile cilia extended from their apical surface, which beat in a coordinated fashion. Here, we used a pool-based short hairpin RNA screening approach and identified TRRAP, an essential component of multiple histone acetyltransferase complexes, as a central regulator of MCC formation. Using a combination of immunofluorescence, signaling pathway modulation, and genomic approaches, we show that (a) TRRAP acts downstream of the Notch2-mediated basal progenitor cell fate decision and upstream of Multicilin to control MCC differentiation; and (b) TRRAP binds to the promoters and regulates the expression of a network of genes involved in MCC differentiation and function, including several genes associated with human ciliopathies. PMID- 29588377 TI - Myosin 1b promotes axon formation by regulating actin wave propagation and growth cone dynamics. AB - Single-headed myosin 1 has been identified in neurons, but its function in these cells is still unclear. We demonstrate that depletion of myosin 1b (Myo1b), inhibition of its motor activity, or its binding to phosphoinositides impairs the formation of the axon, whereas overexpression of Myo1b increases the number of axon-like structures. Myo1b is associated with growth cones and actin waves, two major contributors to neuronal symmetry breaking. We show that Myo1b controls the dynamics of the growth cones and the anterograde propagation of the actin waves. By coupling the membrane to the actin cytoskeleton, Myo1b regulates the size of the actin network as well as the stability and size of filopodia in the growth cones. Our data provide the first evidence that a myosin 1 plays a major role in neuronal symmetry breaking and argue for a mechanical control of the actin cytoskeleton both in actin waves and in the growth cones by this myosin. PMID- 29588379 TI - The Draft Genome of the Invasive Walking Stick, Medauroidea extradendata, Reveals Extensive Lineage-Specific Gene Family Expansions of Cell Wall Degrading Enzymes in Phasmatodea. AB - Plant cell wall components are the most abundant macromolecules on Earth. The study of the breakdown of these molecules is thus a central question in biology. Surprisingly, plant cell wall breakdown by herbivores is relatively poorly understood, as nearly all early work focused on the mechanisms used by symbiotic microbes to breakdown plant cell walls in insects such as termites. Recently, however, it has been shown that many organisms make endogenous cellulases. Insects, and other arthropods, in particular have been shown to express a variety of plant cell wall degrading enzymes in many gene families with the ability to break down all the major components of the plant cell wall. Here we report the genome of a walking stick, Medauroidea extradentata, an obligate herbivore that makes uses of endogenously produced plant cell wall degrading enzymes. We present a draft of the 3.3Gbp genome along with an official gene set that contains a diversity of plant cell wall degrading enzymes. We show that at least one of the major families of plant cell wall degrading enzymes, the pectinases, have undergone a striking lineage-specific gene family expansion in the Phasmatodea. This genome will be a useful resource for comparative evolutionary studies with herbivores in many other clades and will help elucidate the mechanisms by which metazoans breakdown plant cell wall components. PMID- 29588378 TI - ESCRT-III is required for scissioning new peroxisomes from the endoplasmic reticulum. AB - Dynamic control of peroxisome proliferation is integral to the peroxisome's many functions. The endoplasmic reticulum (ER) serves as a source of preperoxisomal vesicles (PPVs) that mature into peroxisomes during de novo peroxisome biogenesis and support growth and division of existing peroxisomes. However, the mechanism of PPV formation and release from the ER remains poorly understood. In this study, we show that endosomal sorting complexes required for transport (ESCRT) III are required to release PPVs budding from the ER into the cytosol. Absence of ESCRT-III proteins impedes de novo peroxisome formation and results in an aberrant peroxisome population in vivo. Using a cell-free PPV budding assay, we show that ESCRT-III proteins Vps20 and Snf7 are necessary to release PPVs from the ER. ESCRT-III is therefore a positive effector of membrane scission for vesicles budding both away from and toward the cytosol. These findings have important implications for the evolutionary timing of emergence of peroxisomes and the rest of the internal membrane architecture of the eukaryotic cell. PMID- 29588380 TI - QTL Mapping of Genome Regions Controlling Manganese Uptake in Lentil Seed. AB - This study evaluated Mn concentration in the seeds of 120 RILs of lentil developed from the cross "CDC Redberry" * "ILL7502". Micronutrient analysis using atomic absorption spectrometry indicated mean seed manganese (Mn) concentrations ranging from 8.5 to 26.8 mg/kg, based on replicated field trials grown at three locations in Turkey in 2012 and 2013. A linkage map of lentil was constructed and consisted of seven linkage groups with 5,385 DNA markers. The total map length was 973.1 cM, with an average distance between markers of 0.18 cM. A total of 6 QTL for Mn concentration were identified using composite interval mapping (CIM). All QTL were statistically significant and explained 15.3-24.1% of the phenotypic variation, with LOD scores ranging from 3.00 to 4.42. The high-density genetic map reported in this study will increase fundamental knowledge of the genome structure of lentil, and will be the basis for the development of micronutrient enriched lentil genotypes to support biofortification efforts. PMID- 29588381 TI - A Bayesian Genomic Regression Model with Skew Normal Random Errors. AB - Genomic selection (GS) has become a tool for selecting candidates in plant and animal breeding programs. In the case of quantitative traits, it is common to assume that the distribution of the response variable can be approximated by a normal distribution. However, it is known that the selection process leads to skewed distributions. There is vast statistical literature on skewed distributions, but the skew normal distribution is of particular interest in this research. This distribution includes a third parameter that drives the skewness, so that it generalizes the normal distribution. We propose an extension of the Bayesian whole-genome regression to skew normal distribution data in the context of GS applications, where usually the number of predictors vastly exceeds the sample size. However, it can also be applied when the number of predictors is smaller than the sample size. We used a stochastic representation of a skew normal random variable, which allows the implementation of standard Markov Chain Monte Carlo (MCMC) techniques to efficiently fit the proposed model. The predictive ability and goodness of fit of the proposed model were evaluated using simulated and real data, and the results were compared to those obtained by the Bayesian Ridge Regression model. Results indicate that the proposed model has a better fit and is as good as the conventional Bayesian Ridge Regression model for prediction, based on the DIC criterion and cross-validation, respectively. A computing program coded in the R statistical package and C programming language to fit the proposed model is available as supplementary material. PMID- 29588382 TI - Distinguishing Among Evolutionary Forces Acting on Genome-Wide Base Composition: Computer Simulation Analysis of Approximate Methods for Inferring Site Frequency Spectra of Derived Mutations. AB - Inferred ancestral nucleotide states are increasingly employed in analyses of within- and between -species genome variation. Although numerous studies have focused on ancestral inference among distantly related lineages, approaches to infer ancestral states in polymorphism data have received less attention. Recently developed approaches that employ complex transition matrices allow us to infer ancestral nucleotide sequence in various evolutionary scenarios of base composition. However, the requirement of a single gene tree to calculate a likelihood is an important limitation for conducting ancestral inference using within-species variation in recombining genomes. To resolve this problem, and to extend the applicability of ancestral inference in studies of base composition evolution, we first evaluate three previously proposed methods to infer ancestral nucleotide sequences among within- and between-species sequence variation data. The methods employ a single allele, bifurcating tree, or a star tree for within species variation data. Using simulated nucleotide sequences, we employ ancestral inference to infer fixations and polymorphisms. We find that all three methods show biased inference. We modify the bifurcating tree method to include weights to adjust for an expected site frequency spectrum, "bifurcating tree with weighting" (BTW). Our simulation analysis show that the BTW method can substantially improve the reliability and robustness of ancestral inference in a range of scenarios that include non-neutral and/or non-stationary base composition evolution.

AB - Autoimmune encephalitis associated with antibodies (Abs) directed against the synaptic ligand-gated ion channel NMDA receptor (NMDAR) was first described as a paraneoplastic disorder in association with ovarian teratoma. Other forms of neoplasia have subsequently been reported although many patients do not have a tumour. Tumour removal, where applicable, and immunotherapy form the mainstays of treatment. We present a patient who developed NMDAR-Ab encephalitis despite being chronically immunosuppressed following organ transplantation, and who was eventually found to have an occult malignancy in the form of non-Hodgkin's lymphoma. PMID- 29588385 TI - Non-vesicular lipid trafficking at the endoplasmic reticulum-mitochondria interface. AB - Mitochondria are highly dynamic organelles involved in various cellular processes such as energy production, regulation of calcium homeostasis, lipid trafficking, and apoptosis. To fulfill all these functions and preserve their morphology and dynamic behavior, mitochondria need to maintain a defined protein and lipid composition in both their membranes. The maintenance of mitochondrial membrane identity requires a selective and regulated transport of specific lipids from/to the endoplasmic reticulum (ER) and across the mitochondria outer and inner membranes. Since they are not integrated in the classical vesicular trafficking routes, mitochondria exchange lipids with the ER at sites of close apposition called membrane contact sites. Deregulation of such transport activities results in several pathologies including cancer and neurodegenerative disorders. However, we are just starting to understand the function of ER-mitochondria contact sites in lipid transport, what are the proteins involved and how they are regulated. In this review, we summarize recent insights into lipid transport pathways at the ER mitochondria interface and discuss the implication of recently identified lipid transfer proteins in these processes. PMID- 29588386 TI - Probing ubiquitin and SUMO conjugation and deconjugation. AB - Ubiquitin (Ub) and ubiquitin-like (Ubl) proteins including small Ubl modifier (SUMO) are small proteins which are covalently linked to target proteins to regulate their functions. In this review, we discuss the current state of the art and point out what we feel this field urgently needs in order to delineate the wiring of the system. We discuss what is needed to unravel the connections between different components of the conjugation machineries for ubiquitylation and SUMOylation, and to unravel the connections between the conjugation machineries and their substrates. Chemical probes are key tools to probe signal transduction by these small proteins that may help understand their action. This rapidly moving field has resulted in various small molecules that will help us to further understand Ub and SUMO function and that may lead to the development of new drugs. PMID- 29588387 TI - Constraint-based modeling in microbial food biotechnology. AB - Genome-scale metabolic network reconstruction offers a means to leverage the value of the exponentially growing genomics data and integrate it with other biological knowledge in a structured format. Constraint-based modeling (CBM) enables both the qualitative and quantitative analyses of the reconstructed networks. The rapid advancements in these areas can benefit both the industrial production of microbial food cultures and their application in food processing. CBM provides several avenues for improving our mechanistic understanding of physiology and genotype-phenotype relationships. This is essential for the rational improvement of industrial strains, which can further be facilitated through various model-guided strain design approaches. CBM of microbial communities offers a valuable tool for the rational design of defined food cultures, where it can catalyze hypothesis generation and provide unintuitive rationales for the development of enhanced community phenotypes and, consequently, novel or improved food products. In the industrial-scale production of microorganisms for food cultures, CBM may enable a knowledge-driven bioprocess optimization by rationally identifying strategies for growth and stability improvement. Through these applications, we believe that CBM can become a powerful tool for guiding the areas of strain development, culture development and process optimization in the production of food cultures. Nevertheless, in order to make the correct choice of the modeling framework for a particular application and to interpret model predictions in a biologically meaningful manner, one should be aware of the current limitations of CBM. PMID- 29588388 TI - SUMOylome Profiling Reveals a Diverse Array of Nuclear Targets Modified by the SUMO Ligase SIZ1 during Heat Stress. AB - The posttranslational addition of small ubiquitin-like modifier (SUMO) is an essential protein modification in plants that provides protection against numerous environmental challenges. Ligation is accomplished by a small set of SUMO ligases, with the SAP-MIZ domain-containing SIZ1 and METHYL METHANESULFONATE SENSITIVE21 (MMS21) ligases having critical roles in stress protection and DNA endoreduplication/repair, respectively. To help identify their corresponding targets in Arabidopsis thaliana, we used siz1 and mms21 mutants for proteomic analyses of SUMOylated proteins enriched via an engineered SUMO1 isoform suitable for mass spectrometric studies. Through multiple data sets from seedlings grown at normal temperatures or exposed to heat stress, we identified over 1000 SUMO targets, most of which are nuclear localized. Whereas no targets could be assigned to MMS21, suggesting that it modifies only a few low abundance proteins, numerous targets could be assigned to SIZ1, including major transcription factors, coactivators/repressors, and chromatin modifiers connected to abiotic and biotic stress defense, some of which associate into multisubunit regulatory complexes. SIZ1 itself is also a target, but studies with mutants protected from SUMOylation failed to uncover a regulatory role. The catalog of SIZ1 substrates indicates that SUMOylation by this ligase provides stress protection by modifying a large array of key nuclear regulators. PMID- 29588389 TI - GRAIN SIZE AND NUMBER1 Negatively Regulates the OsMKKK10-OsMKK4-OsMPK6 Cascade to Coordinate the Trade-off between Grain Number per Panicle and Grain Size in Rice. AB - Grain number and size are interactive agronomic traits that determine grain yield. However, the molecular mechanisms responsible for coordinating the trade off between these traits remain elusive. Here, we characterized the rice (Oryza sativa) grain size and number1 (gsn1) mutant, which has larger grains but sparser panicles than the wild type due to disordered localized cell differentiation and proliferation. GSN1 encodes the mitogen-activated protein kinase phosphatase OsMKP1, a dual-specificity phosphatase of unknown function. Reduced expression of GSN1 resulted in larger and fewer grains, whereas increased expression resulted in more grains but reduced grain size. GSN1 directly interacts with and inactivates the mitogen-activated protein kinase OsMPK6 via dephosphorylation. Consistent with this finding, the suppression of mitogen-activated protein kinase genes OsMPK6, OsMKK4, and OsMKKK10 separately resulted in denser panicles and smaller grains, which rescued the mutant gsn1 phenotypes. Therefore, OsMKKK10 OsMKK4-OsMPK6 participates in panicle morphogenesis and acts on a common pathway in rice. We confirmed that GSN1 is a negative regulator of the OsMKKK10-OsMKK4 OsMPK6 cascade that determines panicle architecture. The GSN1-MAPK module coordinates the trade-off between grain number and grain size by integrating localized cell differentiation and proliferation. These findings provide important insights into the developmental plasticity of the panicle and a potential means to improve crop yields.

PMID- 29588392 TI - Tumor-Infiltrating Lymphocytes and PD-L1 Expression in Pre- and Posttreatment Breast Cancers in the SWOG S0800 Phase II Neoadjuvant Chemotherapy Trial. AB - Our aim was to examine the association of pretreatment tumor-infiltrating lymphocyte (TIL) count and PD-L1 levels with pathologic complete response (pCR) and assess immune marker changes following treatment in tumor specimens from the S0800 clinical trial, which randomized patients to bevacizumab + nab-paclitaxel, followed by doxorubicin/cyclophosphamide (AC) versus two control arms without bevacizumab (varying sequence of AC and nab-paclitaxel). TILs were assessed in 124 pre- and 62 posttreatment tissues (including 59 pairs). PD-L1 was assessed in 120 pre- and 43 posttreatment tissues (including 39 pairs) using the 22C3 antibody. Baseline and treatment-induced immune changes were correlated with pCR and survival using estrogen receptor (ER) and treatment-adjusted logistic and Cox regressions, respectively. At baseline, the mean TIL count was 17.4% (17% had zero TILs, 9% had >=50% TILs). Posttreatment, mean TIL count decreased to 11% (5% had no TILs, 2% had >50% TILs). In paired samples, the mean TIL change was 15% decrease. Baseline PD-L1 was detected in 43% of cases (n = 5 in tumor cells, n = 29 stroma, n = 18 tumor + stroma). Posttreatment, PD-L1 expression was not significantly lower (33%). Higher baseline TIL count and PD-L1 positivity rate were associated with higher pCR rate even after adjustment for treatment and ER status (P = 0.018). There was no association between TIL counts, PD-L1 expression, and survival due to few events. In conclusion, TIL counts, but not PD L1 expression, decreased significantly after treatment. Continued PD-L1 expression in some residual cancers raises the possibility that adjuvant immune checkpoint inhibitor therapy could improve survival in this patient population.

AB - Phytochrome A (phyA) is the primary plant photoreceptor responsible for perceiving and mediating various responses to far-red (FR) light and is essential for survival in canopy shade. In this study, we identified two Arabidopsis thaliana mutants that grew longer hypocotyls in FR light. Genetic analyses showed that they were allelic and their FR phenotypes were caused by mutations in the gene named TANDEM ZINC-FINGER/PLUS3 (TZP), previously shown to encode a nuclear protein involved in blue light signaling and phyB-dependent regulation of photoperiodic flowering. We show that the expression of TZP is dramatically induced by light and that TZP proteins are differentially modified in different light conditions. Furthermore, we show that TZP interacts with both phyA and FAR RED ELONGATED HYPOCOTYL1 (FHY1) and regulates the abundance of phyA, FHY1, and ELONGATED HYPOCOTYL5 proteins in FR light. Moreover, our data indicate that TZP is required for the formation of a phosphorylated form of phyA in the nucleus in FR light. Together, our results identify TZP as a positive regulator of phyA signaling required for phosphorylation of the phyA photoreceptor, thus suggesting an important role of phosphorylated phyA in inducing the FR light response. PMID- 29588393 TI - IMGN779, a Novel CD33-Targeting Antibody-Drug Conjugate with DNA-Alkylating Activity, Exhibits Potent Antitumor Activity in Models of AML. AB - The myeloid differentiation antigen CD33 has long been exploited as a target for antibody-based therapeutic approaches in acute myeloid leukemia (AML). Validation of this strategy was provided with the approval of the CD33-targeting antibody drug conjugate (ADC) gemtuzumab ozogamicin in 2000; the clinical utility of this agent, however, has been hampered by safety concerns. Thus, the full potential of CD33-directed therapy in AML remains to be realized, and considerable interest exists in the design and development of more effective ADCs that confer high therapeutic indices and favorable tolerability profiles. Here, we describe the preclinical characterization of a novel CD33-targeting ADC, IMGN779, which utilizes a unique DNA-alkylating payload to achieve potent antitumor effects with good tolerability. The payload, DGN462, is prototypical of a novel class of purpose-created indolinobenzodiazeprine pseudodimers, termed IGNs. With low picomolar potency, IMGN779 reduced viability in a panel of AML cell lines in vitro Mechanistically, the cytotoxic activity of IMGN779 involved DNA damage, cell-cycle arrest, and apoptosis consistent with the mode of action of DGN462. Moreover, IMGN779 was highly active against patient-derived AML cells, including those with adverse molecular abnormalities, and sensitivity correlated to CD33 expression levels. In vivo, IMGN779 displayed robust antitumor efficacy in multiple AML xenograft and disseminated disease models, as evidenced by durable tumor regressions and prolonged survival. Taken together, these findings identify IMGN779 as a promising new candidate for evaluation as a novel therapeutic in AML. Mol Cancer Ther; 17(6); 1271-9. (c)2018 AACR.

The signalling platform is dependent on cholesterol released from cholesterol esters by cholesterol ester hydrolases (CEHs). The activation of cPLA2 requires cholesterol released from cholesterol esters by cholesterol ester hydrolases (CEHs), enzymes dependent upon platelet activating factor (PAF) released by activated cPLA2 This demonstrates a positive feedback system in which activated cPLA2 increased cholesterol concentrations, which in turn facilitated cPLA2 activation. PAF was also required for the incorporation of the tyrosine kinase Fyn and cyclooxygenase (COX)-2 into Abeta PrPC-cPLA2 complexes. As a failure to deactivate signalling complexes can lead to pathology, the mechanisms involved in their dispersal were studied. PAF facilitated the incorporation of acyl-coenzyme A:cholesterol acyltransferase (ACAT)-1 into Abeta-PrPC-cPLA2-COX-2-Fyn complexes. The esterification of cholesterol reduced cholesterol concentrations, causing dispersal of Abeta-PrPC cPLA2-COX-2-Fyn complexes and the cessation of signalling. This study identifies PAF as a key mediator regulating the cholesterol ester cycle, activation of cPLA2 and COX-2 within synapses, and synapse damage. PMID- 29588395 TI - Substratum stiffness tunes proliferation downstream of Wnt3a in part by regulating integrin-linked kinase and frizzled-1. AB - The Wnt/beta-catenin pathway controls a variety of cellular behaviors, aberrant activation of which are associated with tumor progression in several types of cancer. The same cellular behaviors are also affected by the mechanical properties of the extracellular matrix (ECM) substratum, which induces signaling through integrins and integrin-linked kinase (ILK). Here, we examined the role of substratum stiffness in the regulation of cell proliferation downstream of Wnt3a. We found that treatment with Wnt3a increased proliferation of cells cultured on stiff substrata, with compliances characteristic of breast tumors, but not of cells on soft substrata, with compliances comparable to that of normal mammary tissue. Depleting ILK rendered cells unresponsive to Wnt3a on both substrata. Ectopic expression of ILK permitted Wnt3a to induce proliferation of cells on both microenvironments, although proliferation on soft substrata remained lower than that on stiff substrata. We further showed that ILK regulates expression of the Wnt receptor frizzled-1 (Fzd1), suggesting the presence of a positive feedback loop between Wnt3a, ILK and Fzd1. These findings suggest that tissue mechanics regulates the cellular response to Wnt under physiological and pathological microenvironmental conditions.This article has an associated First Person interview with the first author of the paper. PMID- 29588396 TI - Citron kinase-dependent F-actin maintenance at midbody secondary ingression sites mediates abscission. AB - Abscission is the final step of cytokinesis whereby the intercellular bridge (ICB) linking the two daughter cells is cut. The ICB contains a structure called the midbody, required for the recruitment and organization of the abscission machinery. Final midbody severing is mediated by formation of secondary midbody ingression sites, where the ESCRT III component CHMP4B is recruited to mediate membrane fusion. It is presently unknown how cytoskeletal elements cooperate with CHMP4B to mediate abscission. Here, we show that F-actin is associated with midbody secondary sites and is necessary for abscission. F-actin localization at secondary sites depends on the activity of RhoA and on the abscission regulator citron kinase (CITK). CITK depletion accelerates loss of F-actin proteins at the midbody and subsequent cytokinesis defects are reversed by restoring actin polymerization. Conversely, midbody hyperstabilization produced by overexpression of CITK and ANLN is reversed by actin depolymerization. CITK is required for localization of F-actin and ANLN at the abscission sites, as well as for CHMP4B recruitment. These results indicate that control of actin dynamics downstream of CITK prepares the abscission site for the final cut. PMID- 29588397 TI - Loss of PTEN promotes formation of signaling-capable clathrin-coated pits. AB - Defective endocytosis and vesicular trafficking of signaling receptors has recently emerged as a multifaceted hallmark of malignant cells. Clathrin-coated pits (CCPs) display highly heterogeneous dynamics on the plasma membrane where they can take from 20 s to over 1 min to form cytosolic coated vesicles. Despite the large number of cargo molecules that traffic through CCPs, it is not well understood whether signaling receptors activated in cancer, such as epidermal growth factor receptor (EGFR), are regulated through a specific subset of CCPs. The signaling lipid phosphatidylinositol (3,4,5)-trisphosphate [PI(3,4,5)P3], which is dephosphorylated by phosphatase and tensin homolog (PTEN), is a potent tumorigenic signaling lipid. By using total internal reflection fluorescence microscopy and automated tracking and detection of CCPs, we found that EGF-bound EGFR and PTEN are enriched in a distinct subset of short-lived CCPs that correspond with clathrin-dependent EGF-induced signaling. We demonstrated that PTEN plays a role in the regulation of CCP dynamics. Furthermore, increased PI(3,4,5)P3 resulted in higher proportion of short-lived CCPs, an effect that recapitulates PTEN deletion. Altogether, our findings provide evidence for the existence of short-lived 'signaling-capable' CCPs. PMID- 29588398 TI - The Light Chain Defines the Duration of Action of Botulinum Toxin Serotype A Subtypes. AB - Botulinum neurotoxin (BoNT) is the causative agent of botulism and a widely used pharmaceutical to treat a variety of neurological diseases. BoNTs are 150-kDa protein toxins organized into heavy chain (HC) and light chain (LC) domains linked by a disulfide bond. The HC selectively binds to neurons and aids cell entry of the enzymatically active LC. There are seven immunological BoNT serotypes (A to G); each serotype includes genetic variants, termed subtypes. Only two subtypes, BoNT/A1 and BoNT/B1, are currently used as therapeutics. BoNT serotype A (BoNT/A) subtypes A2 to A8 show distinct potency, duration of action, and pathology relative to BoNT/A1. Specifically, BoNT/A3 possesses shorter duration of action and elicits distinct symptoms in mice at high toxin doses. In this report, we analyzed the roles of LC and HC of BoNT/A3 for duration of action, neuronal cell entry, and mouse pathology by using clostridium-derived recombinant hybrid BoNTs consisting of reciprocal LC and HC (BoNTA1/A3 and BoNTA3/A1). Hybrid toxins were processed in their expression host to a dichain BoNT consisting of LC and HC linked via a disulfide bond. The LC and HC defined BoNT potency in mice and BoNT toxicity for cultured neuronal cells, while the LC defined the duration of BoNT action in cell and mouse models. Protein alignment identified a previously unrecognized region within the LC subtype A3 (LC/A3) relative to the other LC serotype A (LC/A) subtypes (low primary acid homology [LPH]) that correlated to intracellular LC localization. This study shows the utility of recombinant hybrid BoNTs with new therapeutic potential, while remaining sensitive to antitoxins and therapies to native BoNT.IMPORTANCE Botulinum neurotoxins are the most potent protein toxins for humans and potential bioterrorism threats, but they are also widely used as pharmaceuticals. Within the large family of BoNTs, only two subtypes are currently used as pharmaceuticals, with a large number of BoNT subtypes remaining as untapped potential sources for unique pharmaceuticals. Here, two recombinant hybrid toxins were engineered, consisting of domains from two BoNT subtypes that possess distinct duration of action and activity in human neurons and mice. We define the functional domains responsible for BoNT action and demonstrate creation of functional hybrid BoNTs with new therapeutic potential, while remaining sensitive to antitoxins and therapies to native BoNT. PMID- 29588399 TI - Mixed Communities of Mucoid and Nonmucoid Pseudomonas aeruginosa Exhibit Enhanced Resistance to Host Antimicrobials. AB - Pseudomonas aeruginosa causes chronic pulmonary infections in patients with cystic fibrosis (CF). P. aeruginosa mucoid conversion, defined by overproduction of the exopolysaccharide alginate, correlates with accelerated decline in CF patient lung function. Recalcitrance of the mucoid phenotype to clearance by antibiotics and the immune response is well documented. However, despite advantages conferred by mucoidy, mucoid variants often revert to a nonmucoid phenotype both in vitro and in vivo Mixed populations of mucoid isolates and nonmucoid revertants are recovered from CF lungs, suggesting a selective benefit for coexistence of these variants. In this study, cocultures of mucoid and nonmucoid variants exhibited enhanced resistance to two host antimicrobials: LL 37, a cationic antimicrobial peptide, and hydrogen peroxide (H2O2). Alginate production by mucoid isolates protected nonmucoid variants in consortia from LL 37, as addition of alginate exogenously to nonmucoid variants abrogated LL-37 killing. Conversely, nonmucoid revertants shielded mucoid variants from H2O2 stress via catalase (KatA) production, which was transcriptionally repressed by AlgT and AlgR, central regulators of alginate biosynthesis. Furthermore, extracellular release of KatA by nonmucoid revertants was dependent on lys, encoding an endolysin implicated in autolysis and extracellular DNA (eDNA) release. Overall, these data provide a rationale to study interactions of P. aeruginosa mucoid and nonmucoid variants as contributors to evasion of innate immunity and persistence within the CF lung.IMPORTANCEP. aeruginosa mucoid conversion within lungs of cystic fibrosis (CF) patients is a hallmark of chronic infection and predictive of poor prognosis. The selective benefit of mixed populations of mucoid and nonmucoid variants, often isolated from chronically infected CF patients, has not been explored. Here, we show that mixed-variant communities of P. aeruginosa demonstrate advantages in evasion of innate antimicrobials via production of shared goods: alginate and catalase. These data argue for therapeutically targeting multiple constituents (both mucoid and nonmucoid variants) within diversified P. aeruginosa communities in vivo, as these variants can differentially shield one another from components of the host response. PMID- 29588400 TI - HIV-1 Uncoating and Reverse Transcription Require eEF1A Binding to Surface Exposed Acidic Residues of the Reverse Transcriptase Thumb Domain. AB - Once HIV-1 enters a cell, the viral core is uncoated by a poorly understood mechanism and the HIV-1 genomic RNA is reverse transcribed into DNA. Host cell factors are essential for these processes, although very few reverse transcription complex binding host cell factors have been convincingly shown to affect uncoating or reverse transcription. We previously reported that cellular eukaryotic translation elongation factor 1A (eEF1A) interacts tightly and directly with HIV-1 reverse transcriptase (RT) for more efficient reverse transcription. Here we report that the surface-exposed acidic residues in the HIV 1 RT thumb domain alpha-J helix and flanking regions are important for interaction with eEF1A. Mutation of surface-exposed acidic thumb domain residues D250, E297, E298, and E300 to arginine resulted in various levels of impairment of the interaction between RT and eEF1A. This indicates that this negatively charged region in the RT thumb domain is important for interaction with the positively charged eEF1A protein. The impairment of RT and eEF1A interaction by the RT mutations correlated with the efficiency of reverse transcription, uncoating, and infectivity. The best example of this is the strictly conserved E300 residue, where mutation significantly impaired the interaction of RT with eEF1A and virus replication in CD4+ T cells without affecting in vitro RT catalytic activity, RT heterodimerization, or RNase H activity. This study demonstrated that the interaction between surface-exposed acidic residues of the RT thumb domain and eEF1A is important for HIV-1 uncoating, reverse transcription, and replication.IMPORTANCE HIV-1, like all viruses, requires host cell proteins for its replication. Understanding the mechanisms behind virus-host interactions can lay the foundation for future novel therapeutic developments. Our lab has identified eEF1A as a key HIV-1 RT binding host protein that is important for the reverse transcription of HIV-1 genomic RNA into DNA. Here we identify the first surface-exposed RT residues that underpin interactions with eEF1A. Mutation of one strictly conserved RT residue (E300R) delayed reverse transcription and viral core uncoating and strongly inhibited HIV-1 replication in CD4+ T cells. This study advances the structural and mechanistic detail of the key RT-eEF1A interaction in HIV-1 infection and indicates its importance in uncoating for the first time. This provides a further basis for the development of an RT-eEF1A interaction-inhibiting anti-HIV-1 drug and suggests that the surface-exposed acidic patch of the RT thumb domain may be an attractive drug target. PMID- 29588401 TI - Allometry and Ecology of the Bilaterian Gut Microbiome. AB - Classical ecology provides principles for construction and function of biological communities, but to what extent these apply to the animal-associated microbiota is just beginning to be assessed. Here, we investigated the influence of several well-known ecological principles on animal-associated microbiota by characterizing gut microbial specimens from bilaterally symmetrical animals (Bilateria) ranging from flies to whales. A rigorously vetted sample set containing 265 specimens from 64 species was assembled. Bacterial lineages were characterized by 16S rRNA gene sequencing. Previously published samples were also compared, allowing analysis of over 1,098 samples in total. A restricted number of bacterial phyla was found to account for the great majority of gut colonists. Gut microbial composition was associated with host phylogeny and diet. We identified numerous gut bacterial 16S rRNA gene sequences that diverged deeply from previously studied taxa, identifying opportunities to discover new bacterial types. The number of bacterial lineages per gut sample was positively associated with animal mass, paralleling known species-area relationships from island biogeography and implicating body size as a determinant of community stability and niche complexity. Samples from larger animals harbored greater numbers of anaerobic communities, specifying a mechanism for generating more-complex microbial environments. Predictions for species/abundance relationships from models of neutral colonization did not match the data set, pointing to alternative mechanisms such as selection of specific colonists by environmental niche. Taken together, the data suggest that niche complexity increases with gut size and that niche selection forces dominate gut community construction.IMPORTANCE The intestinal microbiome of animals is essential for health, contributing to digestion of foods, proper immune development, inhibition of pathogen colonization, and catabolism of xenobiotic compounds. How these communities assemble and persist is just beginning to be investigated. Here we interrogated a set of gut samples from a wide range of animals to investigate the roles of selection and random processes in microbial community construction. We show that the numbers of bacterial species increased with the weight of host organisms, paralleling findings from studies of island biogeography. Communities in larger organisms tended to be more anaerobic, suggesting one mechanism for niche diversification. Nonselective processes enable specific predictions for community structure, but our samples did not match the predictions of the neutral model. Thus, these findings highlight the importance of niche selection in community construction and suggest mechanisms of niche diversification. PMID- 29588402 TI - Cyclic di-AMP Acts as an Extracellular Signal That Impacts Bacillus subtilis Biofilm Formation and Plant Attachment. AB - There is a growing appreciation for the impact that bacteria have on higher organisms. Plant roots often harbor beneficial microbes, such as the Gram positive rhizobacterium Bacillus subtilis, that influence their growth and susceptibility to disease. The ability to form surface-attached microbial communities called biofilms is crucial for the ability of B. subtilis to adhere to and protect plant roots. In this study, strains harboring deletions of the B. subtilis genes known to synthesize and degrade the second messenger cyclic di adenylate monophosphate (c-di-AMP) were examined for their involvement in biofilm formation and plant attachment. We found that intracellular production of c-di AMP impacts colony biofilm architecture, biofilm gene expression, and plant attachment in B. subtilis We also show that B. subtilis secretes c-di-AMP and that putative c-di-AMP transporters impact biofilm formation and plant root colonization. Taken together, our data describe a new role for c-di-AMP as a chemical signal that affects important cellular processes in the environmentally and agriculturally important soil bacterium B. subtilis These results suggest that the "intracellular" signaling molecule c-di-AMP may also play a previously unappreciated role in interbacterial cell-cell communication within plant microbiomes.IMPORTANCE Plants harbor bacterial communities on their roots that can significantly impact their growth and pathogen resistance. In most cases, however, the signals that mediate host-microbe and microbe-microbe interactions within these communities are unknown. A detailed understanding of these interaction mechanisms could facilitate the manipulation of these communities for agricultural or environmental purposes. Bacillus subtilis is a plant-growth promoting bacterium that adheres to roots by forming biofilms. We therefore began by exploring signals that might impact its biofilm formation. We found that B. subtilis secretes c-di-AMP and that the ability to produce, degrade, or transport cyclic di-adenylate monophosphate (c-di-AMP; a common bacterial second messenger) affects B. subtilis biofilm gene expression and plant attachment. To our knowledge, this is the first demonstration of c-di-AMP impacting a mutualist host microbe association and suggests that c-di-AMP may function as a previously unappreciated extracellular signal able to mediate interactions within plant microbiomes. PMID- 29588403 TI - Exogenous Stimulation of Type I Interferon Protects Mice with Chronic Granulomatous Disease from Aspergillosis through Early Recruitment of Host Protective Neutrophils into the Lung. AB - Invasive aspergillosis (IA) remains the primary cause of morbidity and mortality in chronic granulomatous disease (CGD) patients, often due to infection by Aspergillus species refractory to antifungals. This motivates the search for alternative treatments, including immunotherapy. We investigated the effect of exogenous type I interferon (IFN) activation on the outcome of IA caused by three Aspergillus species, A. fumigatus, A. nidulans, and A. tanneri, in CGD mice. The animals were treated with poly(I):poly(C) carboxymethyl cellulose poly-l-lysine (PICLC), a mimetic of double-stranded RNA, 24 h preinfection and postinfection. The survival rates and lung fungal burdens were markedly improved by PICLC immunotherapy in animals infected with any one of the three Aspergillus species. While protection from IA was remarkable, PICLC induction of type I IFN in the lungs surged 24 h posttreatment and returned to baseline levels by 48 h, suggesting that PICLC altered early events in protection against IA. Immunophenotyping of recruited leukocytes and histopathological examination of tissue sections showed that PICLC induced similar cellular infiltrates as those in untreated-infected mice, in both cases dominated by monocytic cells and neutrophils. However, the PICLC immunotherapy resulted in a marked earlier recruitment of the leukocytes. Unlike with conidia, infection with A. nidulans germlings reduced the protective effect of PICLC immunotherapy. Additionally, antibody depletion of neutrophils totally reversed the protection, suggesting that neutrophils are crucial for PICLC-mediated protection. Together, these data show that prophylactic PICLC immunotherapy prerecruits these cells, enabling them to attack the conidia and thus resulting in a profound protection from IA.IMPORTANCE Patients with chronic granulomatous disease (CGD) are highly susceptible to invasive aspergillosis (IA). While Aspergillus fumigatus is the most-studied Aspergillus species, CGD patients often suffer IA caused by A. nidulans, A. tanneri, and other rare species. These non-fumigatus Aspergillus species are more resistant to antifungal drugs and cause higher fatality rates than A. fumigatus Therefore, alternative therapies are needed to protect CGD patients. We report an effective immunotherapy of mice infected with three Aspergillus species via PICLC dosing. While protection from IA was long lasting, PICLC induction of type I IFN surged but quickly returned to baseline levels, suggesting that PICLC was altering early events in IA. Interestingly, we found responding immune cells to be similar between PICLC-treated and untreated infected mice. However, PICLC immunotherapy resulted in an earlier recruitment of the leukocytes and suppressed fungal growth. This study highlights the value of type I IFN induction in CGD patients. PMID- 29588404 TI - The Typhoid Toxin Produced by the Nontyphoidal Salmonella enterica Serotype Javiana Is Required for Induction of a DNA Damage Response In Vitro and Systemic Spread In Vivo. AB - The Salmonella cytolethal distending toxin (S-CDT), first described as the "typhoid toxin" in Salmonella enterica subsp. enterica serotype Typhi, induces DNA damage in eukaryotic cells. Recent studies have shown that more than 40 nontyphoidal Salmonella (NTS) serotypes carry genes that encode S-CDT, yet very little is known about the activity, function, and role of S-CDT in NTS. Here we show that deletion of genes encoding the binding subunit (pltB) and a bacteriophage muramidase predicted to play a role in toxin export (ttsA) does not abolish toxin activity in the S-CDT-positive NTS Salmonella enterica subsp. enterica serotype Javiana. However, S. Javiana strains harboring deletions of both pltB and its homolog artB, had a complete loss of S-CDT activity, suggesting that S. Javiana carries genes encoding two variants of the binding subunit. S-CDT mediated DNA damage, as determined by phosphorylation of histone 2AX (H2AX), producing phosphorylated H2AX (gammaH2AX), was restricted to epithelial cells in S and G2/M phases of the cell cycle and did not result in apoptosis or cell death. Compared to mice infected with a DeltacdtB strain, mice infected with wild type S. Javiana had significantly higher levels of S. Javiana in the liver, but not in the spleen, ileum, or cecum. Overall, we show that production of active S CDT by NTS serotype S. Javiana requires different genes (cdtB, pltA, and either pltB or artB) for expression of biologically active toxin than those reported for S-CDT production by S. Typhi (cdtB, pltA, pltB, and ttsA). However, as in S. Typhi, NTS S-CDT influences the outcome of infection both in vitro and in vivoIMPORTANCE Nontyphoidal Salmonella (NTS) are a major cause of bacterial food borne illness worldwide; however, our understanding of virulence mechanisms that determine the outcome and severity of nontyphoidal salmonellosis is incompletely understood. Here we show that S-CDT produced by NTS plays a significant role in the outcome of infection both in vitro and in vivo, highlighting S-CDT as an important virulence factor for nontyphoidal Salmonella serotypes. Our data also contribute novel information about the function of S-CDT, as S-CDT-mediated DNA damage occurs only during certain phases of the cell cycle, and the resulting damage does not induce cell death as assessed using a propidium iodide exclusion assay. Importantly, our data support that, despite having genetically similar S CDT operons, NTS serotype S. Javiana has different genetic requirements than S. Typhi, for the production and export of active S-CDT. PMID- 29588406 TI - Robust Phagocyte Recruitment Controls the Opportunistic Fungal Pathogen Mucor circinelloides in Innate Granulomas In Vivo. AB - Mucormycosis is an emerging fungal infection with extremely high mortality rates in patients with defects in their innate immune response, specifically in functions mediated through phagocytes. However, we currently have a limited understanding of the molecular and cellular interactions between these innate immune effectors and mucormycete spores during the early immune response. Here, the early events of innate immune recruitment in response to infection by Mucor circinelloides spores are modeled by a combined in silico modeling approach and real-time in vivo microscopy. Phagocytes are rapidly recruited to the site of infection in a zebrafish larval model of mucormycosis. This robust early recruitment protects from disease onset in vivoIn silico analysis identified that protection is dependent on the number of phagocytes at the infection site, but not the speed of recruitment. The mathematical model highlights the role of proinflammatory signals for phagocyte recruitment and the importance of inhibition of spore germination for protection from active fungal disease. These in silico data are supported by an in vivo lack of fungal spore killing and lack of reactive oxygen burst, which together result in latent fungal infection. During this latent stage of infection, spores are controlled in innate granulomas in vivo Disease can be reactivated by immunosuppression. Together, these data represent the first in vivo real-time analysis of innate granuloma formation during the early stages of a fungal infection. The results highlight a potential latent stage during mucormycosis that should urgently be considered for clinical management of patients.IMPORTANCE Mucormycosis is a dramatic fungal infection frequently leading to the death of patients. We know little about the immune response to the fungus causing this infection, although evidence points toward defects in early immune events after infection. Here, we dissect this early immune response to infectious fungal spores. We show that specialized white blood cells (phagocytes) rapidly respond to these spores and accumulate around the fungus. However, we demonstrate that the mechanisms that enable phagocytes to kill the fungus fail, allowing for survival of spores. Instead a cluster of phagocytes resembling an early granuloma is formed around spores to control the latent infection. This study is the first detailed analysis of early granuloma formation during a fungal infection highlighting a latent stage that needs to be considered for clinical management of patients. PMID- 29588405 TI - Concurrent Host-Pathogen Transcriptional Responses in a Clostridium perfringens Murine Myonecrosis Infection. AB - To obtain an insight into host-pathogen interactions in clostridial myonecrosis, we carried out comparative transcriptome analysis of both the bacterium and the host in a murine Clostridium perfringens infection model, which is the first time that such an investigation has been conducted. Analysis of the host transcriptome from infected muscle tissues indicated that many genes were upregulated compared to the results seen with mock-infected mice. These genes were enriched for host defense pathways, including Toll-like receptor (TLR) and Nod-like receptor (NLR) signaling components. Real-time PCR confirmed that host TLR2 and NLRP3 inflammasome genes were induced in response to C. perfringens infection. Comparison of the transcriptome of C. perfringens cells from the infected tissues with that from broth cultures showed that host selective pressure induced a global change in C. perfringens gene expression. A total of 33% (923) of C. perfringens genes were differentially regulated, including 10 potential virulence genes that were upregulated relative to their expression in vitro These genes encoded putative proteins that may be involved in the synthesis of cell wall associated macromolecules, in adhesion to host cells, or in protection from host cationic antimicrobial peptides. This report presents the first successful expression profiling of coregulated transcriptomes of bacterial and host genes during a clostridial myonecrosis infection and provides new insights into disease pathogenesis and host-pathogen interactions.IMPORTANCEClostridium perfringens is the causative agent of traumatic clostridial myonecrosis, or gas gangrene. In this study, we carried out transcriptional analysis of both the host and the bacterial pathogen in a mouse myonecrosis infection. The results showed that in comparison to mock-infected control tissues, muscle tissues from C. perfringens infected mice had a significantly altered gene expression profile. In particular, the expression of many genes involved in the innate immune system was upregulated. Comparison of the expression profiles of C. perfringens cells isolated from the infected tissues with those from equivalent broth cultures identified many potential virulence genes that were significantly upregulated in vivo These studies have provided a new understanding of the range of factors involved in host-pathogen interactions in a myonecrosis infection. PMID- 29588407 TI - The Sole DEAD-Box RNA Helicase of the Gastric Pathogen Helicobacter pylori Is Essential for Colonization. AB - Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures. Most bacteria have multiple DEAD-box helicases that present both specialized and partially redundant functions. By using phylogenomics, we revealed that the Helicobacter genus, including the major gastric pathogen H. pylori, is among the exceptions, as it encodes a sole DEAD-box RNA helicase. In H. pylori, this helicase, designated RhpA, forms a minimal RNA degradosome together with the essential RNase, RNase J, a major player in the control of RNA decay. Here, we used H. pylori as a model organism with a sole DEAD-box helicase and investigated the role of this helicase in H. pylori physiology, ribosome assembly, and during in vivo colonization. Our data showed that RhpA is dispensable for growth at 37 degrees C but crucial at 33 degrees C, suggesting an essential role of the helicase in cold adaptation. Moreover, we found that a DeltarhpA mutant was impaired in motility and deficient in colonization of the mouse model. RhpA is involved in the maturation of 16S rRNA at 37 degrees C and is associated with translating ribosomes. At 33 degrees C, RhpA is, in addition, recruited to individual ribosomal subunits. Finally, via its role in the RNA degradosome, RhpA directs the regulation of the expression of its partner, RNase J. RhpA is thus a multifunctional enzyme that, in H. pylori, plays a central role in gene regulation and in the control of virulence.IMPORTANCE We present the results of our study on the role of RhpA, the sole DEAD-box RNA helicase encoded by the major gastric pathogen Helicobacter pylori We observed that all the Helicobacter species possess such a sole helicase, in contrast to most free living bacteria. RhpA is not essential for growth of H. pylori under normal conditions. However, deletion of rhpA leads to a motility defect and to total inhibition of the ability of H. pylori to colonize a mouse model. We also demonstrated that this helicase encompasses most of the functions of its specialized orthologs described so far. We found that RhpA is a key element of the bacterial adaptation to colder temperatures and plays a minor role in ribosome biogenesis. Finally, RhpA regulates transcription of the rnj gene encoding RNase J, its essential partner in the minimal H. pylori RNA degradosome, and thus plays a crucial role in the control of RNA decay. PMID- 29588408 TI - Redox Regulation, Rather than Stress-Induced Phosphorylation, of a Hog1 Mitogen Activated Protein Kinase Modulates Its Nitrosative-Stress-Specific Outputs. AB - In all eukaryotic kingdoms, mitogen-activated protein kinases (MAPKs) play critical roles in cellular responses to environmental cues. These MAPKs are activated by phosphorylation at highly conserved threonine and tyrosine residues in response to specific inputs, leading to their accumulation in the nucleus and the activation of their downstream targets. A specific MAP kinase can regulate different downstream targets depending on the nature of the input signal, thereby raising a key question: what defines the stress-specific outputs of MAP kinases? We find that the Hog1 MAPK contributes to nitrosative-stress resistance in Candida albicans even though it displays minimal stress-induced phosphorylation under these conditions. We show that Hog1 becomes oxidized in response to nitrosative stress, accumulates in the nucleus, and regulates the nitrosative stress-induced transcriptome. Mutation of specific cysteine residues revealed that C156 and C161 function together to promote stress resistance, Hog1-mediated nitrosative-stress-induced gene expression, resistance to phagocytic killing, and C. albicans virulence. We propose that the oxidation of Hog1, rather than its phosphorylation, contributes to the nitrosative-stress-specific responses of this MAP kinase.IMPORTANCE Mitogen-activated protein kinases play key roles in the responses of eukaryotic cells to extracellular signals and are critical for environmental-stress resistance. The widely accepted paradigm is that MAP kinases are activated by phosphorylation, which then triggers their nuclear accumulation and the activation of target proteins and genes that promote cellular adaptation. Our data suggest that alternative forms of posttranslational modification can modulate MAP kinase functionality in Candida albicans We demonstrate that Hog1 is not significantly phosphorylated in response to nitrosative stress, yet it displays nuclear accumulation and contributes to the global transcriptional response to this stress, as well as promoting nitrosative-stress resistance. Instead, nitrosative stress triggers changes in the redox status of Hog1. We also show that specific Hog1 cysteine residues influence its activation of stress genes. Therefore, alternative posttranslational modifications appear to regulate the stress-specific outputs of MAP kinases. PMID- 29588409 TI - Physiological Effect of XoxG(4) on Lanthanide-Dependent Methanotrophy. AB - A recent surprising discovery of the activity of rare earth metals (lanthanides) as enzyme cofactors as well as transcriptional regulators has overturned the traditional assumption of biological inertia of these metals. However, so far, examples of such activities have been limited to alcohol dehydrogenases. Here we describe the physiological effects of a mutation in xoxG, a gene encoding a novel cytochrome, XoxG(4), and compare these to the effects of mutation in XoxF, a lanthanide-dependent methanol dehydrogenase, at the enzyme activity level and also at the community function level, using Methylomonas sp. strain LW13 as a model organism. Through comparative phenotypic characterization, we establish XoxG as the second protein directly involved in lanthanide-dependent metabolism, likely as a dedicated electron acceptor from XoxF. However, mutation in XoxG caused a phenotype that was dramatically different from the phenotype of the mutant in XoxF, suggesting a secondary function for this cytochrome, in metabolism of methane. We also purify XoxG(4) and demonstrate that this protein is a true cytochrome c, based on the typical absorption spectra, and we demonstrate that XoxG can be directly reduced by a purified XoxF, supporting one of its proposed physiological functions. Overall, our data continue to suggest the complex nature of the interplay between the calcium-dependent and lanthanide dependent alcohol oxidation systems, while they also suggest that addressing the roles of these alternative systems is essential at the enzyme and community function level, in addition to the gene transcription level.IMPORTANCE The lanthanide-dependent biochemistry of living organisms remains a barely tapped area of knowledge. So far, only a handful of lanthanide-dependent alcohol dehydrogenases have been described, and their regulation by lanthanides has been demonstrated at the transcription level. Little information is available regarding the concentrations of lanthanides that could support sufficient enzymatic activities to support specific metabolisms, and so far, no other redox proteins involved in lanthanide-dependent methanotrophy have been demonstrated. The research presented here provides enzyme activity-level data on lanthanide dependent methanotrophy in a model methanotroph. Additionally, we identify a second protein important for lanthanide-dependent metabolism in this organism, XoxG(4), a novel cytochrome. XoxG(4) appears to have multiple functions in methanotrophy, one function as an electron acceptor from XoxF and another function remaining unknown. On the basis of the dramatic phenotype of the XoxG(4) mutant, this function must be crucial for methanotrophy.

AB - OBJECTIVES: The purpose of this study was to investigate the contribution of neighbourhood disorder around alcohol outlets to pedestrian injury risk. METHODS: A spatial analysis was conducted on census block groups in Baltimore City. Data included pedestrian injury EMS records from 1 January 2014 to 15 April 2015 (n=858), off-premise alcohol outlet locations for 2014 (n=693) and neighbourhood disorder indicators and demographics. Negative binomial regression models were used to determine the relationship between alcohol outlet count and pedestrian injuries at the block group level, controlling for other neighbourhood factors. Attributable risk was calculated by comparing the total population count per census block group to the injured pedestrian count. RESULTS: Each one-unit increase in the number of alcohol outlets was associated with a 14.2% (95% CI 1.099 to 1.192, P<0.001) increase in the RR of neighbourhood pedestrian injury, adjusting for traffic volume, pedestrian volume, population density, per cent of vacant lots and median household income. The attributable risk was 10.4% (95% CI 7.7 to 12.7) or 88 extra injuries. Vacant lots was the only significant neighbourhood disorder indicator in the final adjusted model (RR=1.016, 95% CI 1.007 to 1.026, P=0.003). Vacant lots have not been previously investigated as possible risk factors for pedestrian injury. CONCLUSIONS: This study identifies modifiable risk factors for pedestrian injury previously unexplored in the literature and may provide evidence for alcohol control strategies (eg, liquor store licencing, zoning and enforcement).

AB - Cancer cells can remodel surrounding microenvironments to facilitate cell growth, invasion, and migration by secreting proteins that educate surrounding stromal cells. We report that p85S6K1, the longest isoform of S6K (ribosomal protein S6 kinase), but not the shorter isoform p70S6K1 or p56S6K2, was secreted from cancer cells through its HIV TAT-like, N-terminal six-arginine motif. The exogenously produced p85S6K1 protein entered cultured transformed and nontransformed cells to promote or confer malignant behaviors, leading to increased cell growth and migration. When injected into mice, the p85S6K1 protein enhanced the growth of xenografted breast cancer cells and lung metastasis. Hence, our findings reveal a role for p85S6K1 as a secreted oncogenic kinase and provide a mechanism by which cancer cells remodel their microenvironment by transforming the surrounding cells to drive tumorigenesis.

AB - Palmitoylation of delta-catenin is critical to synapse plasticity and memory formation. We found that delta-catenin palmitoylation is also instrumental in the development of neuropathic pain. The abundances of palmitoylated delta-catenin and the palmitoyl acyltransferase DHHC3 were increased in dorsal root ganglion (DRG) sensory neurons in rat models of neuropathic pain. Inhibiting palmitoyl acyltransferases or decreasing delta-catenin abundance in the DRG by intrathecal injection of 2-bromopalmitate or shRNA, respectively, alleviated oxaliplatin or nerve injury-induced neuropathic pain in the rats. The palmitoylation of delta catenin, which was induced by the inflammatory cytokine TNF-alpha, facilitated its interaction with the voltage-gated sodium channel Nav1.6 and the kinesin motor protein KIF3A, which promoted the trafficking of Nav1.6 to the plasma membrane in DRG neurons and contributed to mechanical hypersensitivity and allodynia in rats. These findings suggest that a palmitoylation-mediated KIF3A/delta-catenin/Nav1.6 complex enhances the transmission of mechanical and nociceptive signals; thus, blocking this mechanism may be therapeutic in patients with neuropathic pain.

AB - The transforming growth factor-beta (TGF-beta) superfamily of cytokines regulates various biological processes, including cell proliferation, immune responses, autophagy, and senescence. Dysregulation of TGF-beta signaling causes various diseases, such as cancer and fibrosis. SMAD2 and SMAD3 are core transcription factors involved in TGF-beta signaling, and they form heterotrimeric complexes with SMAD4 (SMAD2-SMAD2-SMAD4, SMAD3-SMAD3-SMAD4, and SMAD2-SMAD3-SMAD4) in response to TGF-beta signaling. These heterotrimeric complexes interact with cofactors to control the expression of TGF-beta-dependent genes. SMAD2 and SMAD3 may promote or repress target genes depending on whether they form complexes with other transcription factors, coactivators, or corepressors; therefore, the selection of specific cofactors is critical for the appropriate activity of these transcription factors. To reveal the structural basis by which SMAD2 and SMAD3 select cofactors, we determined the crystal structures of SMAD3 in complex with the transcription factor FOXH1 and SMAD2 in complex with the transcriptional corepressor SKI. The structures of the complexes show that the MAD homology 2 (MH2) domains of SMAD2 and SMAD3 have multiple hydrophobic patches on their surfaces. The cofactors tether to various subsets of these patches to interact with SMAD2 and SMAD3 in a cooperative or competitive manner to control the output of TGF-beta signaling.

PMID- 29588415 TI - Nonmonotonic spatial structure of interneuronal correlations in prefrontal microcircuits. AB - Correlated fluctuations of single neuron discharges, on a mesoscopic scale, decrease as a function of lateral distance in early sensory cortices, reflecting a rapid spatial decay of lateral connection probability and excitation. However, spatial periodicities in horizontal connectivity and associational input as well as an enhanced probability of lateral excitatory connections in the association cortex could theoretically result in nonmonotonic correlation structures. Here, we show such a spatially nonmonotonic correlation structure, characterized by significantly positive long-range correlations, in the inferior convexity of the macaque prefrontal cortex. This functional connectivity kernel was more pronounced during wakefulness than anesthesia and could be largely attributed to the spatial pattern of correlated variability between functionally similar neurons during structured visual stimulation. These results suggest that the spatial decay of lateral functional connectivity is not a common organizational principle of neocortical microcircuits. A nonmonotonic correlation structure could reflect a critical topological feature of prefrontal microcircuits, facilitating their role in integrative processes. PMID- 29588416 TI - Programmed cell death 5 suppresses AKT-mediated cytoprotection of endothelium. AB - Programmed cell death 5 (PDCD5) has been associated with human cancers as a regulator of cell death; however, the role of PDCD5 in the endothelium has not been revealed. Thus, we investigated whether PDCD5 regulates protein kinase B (PKB/AKT)-endothelial nitric oxide synthase (eNOS)-dependent signal transduction in the endothelium and affects atherosclerosis. Endothelial-specific PDCD5 knockout mice showed significantly reduced vascular remodeling compared with wild type (WT) mice after partial carotid ligation. WT PDCD5 competitively inhibited interaction between histone deacetylase 3 (HDAC3) and AKT, but PDCD5L6R, an HDAC3 binding-deficient mutant, did not. Knockdown of PDCD5 accelerated HDAC3-AKT interaction, AKT and eNOS phosphorylation, and nitric oxide (NO) production in human umbilical vein endothelial cells. Moreover, we found that serum PDCD5 levels reflect endothelial NO production and are correlated with diabetes mellitus, high-density lipoprotein cholesterol, and coronary calcium in human samples obtained from the cardiovascular high-risk cohort. Therefore, we conclude that PDCD5 is associated with endothelial dysfunction and may be a novel therapeutic target in atherosclerosis. PMID- 29588417 TI - Local protein solvation drives direct down-conversion in phycobiliprotein PC645 via incoherent vibronic transport. AB - The mechanisms controlling excitation energy transport (EET) in light-harvesting complexes remain controversial. Following the observation of long-lived beats in 2D electronic spectroscopy of PC645, vibronic coherence, the delocalization of excited states between pigments supported by a resonant vibration, has been proposed to enable direct excitation transport from the highest-energy to the lowest-energy pigments, bypassing a collection of intermediate states. Here, we instead show that for phycobiliprotein PC645 an incoherent vibronic transport mechanism is at play. We quantify the solvation dynamics of individual pigments using ab initio quantum mechanics/molecular mechanics (QM/MM) nuclear dynamics. Our atomistic spectral densities reproduce experimental observations ranging from absorption and fluorescence spectra to the timescales and selectivity of down conversion observed in transient absorption measurements. We construct a general model for vibronic dimers and establish the parameter regimes of coherent and incoherent vibronic transport. We demonstrate that direct down-conversion in PC645 proceeds incoherently, enhanced by large reorganization energies and a broad collection of high-frequency vibrations. We suggest that a similar incoherent mechanism is appropriate across phycobiliproteins and represents a potential design principle for nanoscale control of EET. PMID- 29588418 TI - Successful reprogramming of cellular protein production through mRNA delivered by functionalized lipid nanoparticles. AB - The development of safe and efficacious gene vectors has limited greatly the potential for therapeutic treatments based on messenger RNA (mRNA). Lipid nanoparticles (LNPs) formed by an ionizable cationic lipid (here DLin-MC3-DMA), helper lipids (distearoylphosphatidylcholine, DSPC, and cholesterol), and a poly(ethylene glycol) (PEG) lipid have been identified as very promising delivery vectors of short interfering RNA (siRNA) in different clinical phases; however, delivery of high-molecular weight RNA has been proven much more demanding. Herein we elucidate the structure of hEPO modified mRNA-containing LNPs of different sizes and show how structural differences affect transfection of human adipocytes and hepatocytes, two clinically relevant cell types. Employing small-angle scattering, we demonstrate that LNPs have a disordered inverse hexagonal internal structure with a characteristic distance around 6 nm in presence of mRNA, whereas LNPs containing no mRNA do not display this structure. Furthermore, using contrast variation small-angle neutron scattering, we show that one of the lipid components, DSPC, is localized mainly at the surface of mRNA-containing LNPs. By varying LNP size and surface composition we demonstrate that both size and structure have significant influence on intracellular protein production. As an example, in both human adipocytes and hepatocytes, protein expression levels for 130 nm LNPs can differ as much as 50-fold depending on their surface characteristics, likely due to a difference in the ability of LNP fusion with the early endosome membrane. We consider these discoveries to be fundamental and opening up new possibilities for rational design of synthetic nanoscopic vehicles for mRNA delivery. PMID- 29588419 TI - TWEAK and RIPK1 mediate a second wave of cell death during AKI. AB - Acute kidney injury (AKI) is characterized by necrotic tubular cell death and inflammation. The TWEAK/Fn14 axis is a mediator of renal injury. Diverse pathways of regulated necrosis have recently been reported to contribute to AKI, but there are ongoing discussions on the timing or molecular regulators involved. We have now explored the cell death pathways induced by TWEAK/Fn14 activation and their relevance during AKI. In cultured tubular cells, the inflammatory cytokine TWEAK induces apoptosis in a proinflammatory environment. The default inhibitor of necroptosis [necrostatin-1 (Nec-1)] was protective, while caspase inhibition switched cell death to necroptosis. Additionally, folic acid-induced AKI in mice resulted in increased expression of Fn14 and necroptosis mediators, such as receptor-interacting protein kinase 1 (RIPK1), RIPK3, and mixed lineage domain like protein (MLKL). Targeting necroptosis with Nec-1 or by genetic RIPK3 deficiency and genetic Fn14 ablation failed to be protective at early time points (48 h). However, a persistently high cell death rate and kidney dysfunction (72 96 h) were dependent on an intact TWEAK/Fn14 axis driving necroptosis. This was prevented by Nec-1, or MLKL, or RIPK3 deficiency and by Nec-1 stable (Nec-1s) administered before or after induction of AKI. These data suggest that initial kidney damage and cell death are amplified through recruitment of inflammation dependent necroptosis, opening a therapeutic window to treat AKI once it is established. This may be relevant for clinical AKI, since using current diagnostic criteria, severe injury had already led to loss of renal function at diagnosis.

PMID- 29588420 TI - Comprehensive, high-resolution binding energy landscapes reveal context dependencies of transcription factor binding. AB - Transcription factors (TFs) are primary regulators of gene expression in cells, where they bind specific genomic target sites to control transcription. Quantitative measurements of TF-DNA binding energies can improve the accuracy of predictions of TF occupancy and downstream gene expression in vivo and shed light on how transcriptional networks are rewired throughout evolution. Here, we present a sequencing-based TF binding assay and analysis pipeline (BET-seq, for Binding Energy Topography by sequencing) capable of providing quantitative estimates of binding energies for more than one million DNA sequences in parallel at high energetic resolution. Using this platform, we measured the binding energies associated with all possible combinations of 10 nucleotides flanking the known consensus DNA target interacting with two model yeast TFs, Pho4 and Cbf1. A large fraction of these flanking mutations change overall binding energies by an amount equal to or greater than consensus site mutations, suggesting that current definitions of TF binding sites may be too restrictive. By systematically comparing estimates of binding energies output by deep neural networks (NNs) and biophysical models trained on these data, we establish that dinucleotide (DN) specificities are sufficient to explain essentially all variance in observed binding behavior, with Cbf1 binding exhibiting significantly more nonadditivity than Pho4. NN-derived binding energies agree with orthogonal biochemical measurements and reveal that dynamically occupied sites in vivo are both energetically and mutationally distant from the highest affinity sites.

PMID- 29588426 TI - SULFATION PATHWAYS: Potential benefits of a sulfated resveratrol derivative for topical application. AB - Resveratrol (RSV) is a polyphenolic compound with antioxidant, anti-inflammatory and anti-aging properties partly associated with sirtuin 1 (SIRT1)-activation in the skin. However, poor water solubility may limit RSV efficacy. This work aimed to clarify the interest of a new synthetic water-soluble RSV derivative (resveratrol glucoside sulfate, RSV-GS) for topical application. Resveratrol glucoside sulfate was synthesized using microwave-assisted sulfation. Cytotoxicity assays were performed with the keratinocyte HaCaT cell line, using MTT reduction, neutral red uptake, Alamar Blue/resazurin reduction, trypan blue exclusion and measurement of ATP concentration. Western blotting was used to evaluate SIRT1 protein content. Regarding SIRT1 binding, an in silico docking study was performed, using AutoDock Vina. Our results showed that the synthetic derivative RSV-GS was 1000 times more soluble in water than RSV and its non sulfated glucoside. No relevant decrease in HaCaT cell viability was observed for concentrations up to 5 mM for RSV-GS, and up to 500 MUM for resveratrol glucoside, while a significant decrease in HaCaT viability occurred from 100 MUM for RSV. RSV-GS and RSV showed a similar behavior regarding protective effect against oxidative stress-induced cytotoxicity. SIRT1 protein content increased after treatment with 500 MUM of RSV-GS and 100 MUM of RSV. Moreover, in silico studies predicted that RSV-GS binds more stably to SIRT1 with a lower binding free energy than RSV. Although these results support the possible use of RSV-GS in topical formulations, in vivo safety and efficacy studies are needed before considering the use of RSV-GS in commercial products. PMID- 29588428 TI - SULFATION PATHWAYS: Expression of SULT2A1, SULT2B1 and HSD3B1 in the porcine testis and epididymis. AB - In the porcine testis, in addition to estrogen sulfates, the formation of numerous sulfonated neutral hydroxysteroids has been observed. However, their functions and the underlying synthetic pathways are still widely unclear. To obtain further information on their formation in postpubertal boars, the expression of sulfotransferases considered relevant for neutral hydroxysteroids (SULT2A1, SULT2B1) was investigated in the testis and defined segments of the epididymis applying real-time RT-qPCR, Western blot and immunohistochemistry (IHC). Sulfotransferase activities were assessed in tissue homogenates or cytosolic preparations applying dehydroepiandrosterone and pregnenolone as substrates. A high SULT2A1 expression was confirmed in the testis and localized in Leydig cells by IHC. In the epididymis, SULT2A1 expression was virtually confined to the body. SULT2B1 expression was absent or low in the testis but increased significantly along the epididymis. Immunohistochemical observations indicate that both enzymes are secreted into the ductal lumen via an apocrine mechanism. The results from the characterization of expression patterns and activity measurements suggest that SULT2A1 is the prevailing enzyme for the sulfonation of hydroxysteroids in the testis, whereas SULT2B1 may catalyze the formation of sterol sulfates in the epididymis. In order to obtain information on the overall steroidogenic capacity of the porcine epididymis, the expression of important steroidogenic enzymes (CYP11A1, CYP17A1, CYP19, HSD3B1, HSD17B3, SRD5A2) was monitored in the defined epididymal segments applying real-time RT qPCR. Surprisingly, in addition to a high expression of SRD5A2 in the epididymal head, a substantial expression of HSD3B1 was detected, which increased along the organ. PMID- 29588427 TI - Molecular mechanisms of glucocorticoids on skeleton and bone regeneration after fracture. AB - Glucocorticoid hormones (GCs) have profound effects on bone metabolism. Via their nuclear hormone receptor - the GR - they act locally within bone cells and modulate their proliferation, differentiation, and cell death. Consequently, high glucocorticoid levels - as present during steroid therapy or stress - impair bone growth and integrity, leading to retarded growth and glucocorticoid-induced osteoporosis, respectively. Because of their profound impact on the immune system and bone cell differentiation, GCs also affect bone regeneration and fracture healing. The use of conditional-mutant mouse strains in recent research provided insights into the cell-type-specific actions of the GR. However, despite recent advances in system biology approaches addressing GR genomics in general, little is still known about the molecular mechanisms of GCs and GR in bone cells. Here, we review the most recent findings on the molecular mechanisms of the GR in general and the known cell-type-specific actions of the GR in mesenchymal cells and their derivatives as well as in osteoclasts during bone homeostasis, GC excess, bone regeneration and fracture healing. PMID- 29588429 TI - Hydroxyproline Metabolism and Oxalate Synthesis in Primary Hyperoxaluria. AB - Background Endogenous oxalate synthesis contributes to calcium oxalate stone disease and is markedly increased in the inherited primary hyperoxaluria (PH) disorders. The incomplete knowledge regarding oxalate synthesis complicates discovery of new treatments. Hydroxyproline (Hyp) metabolism results in the formation of oxalate and glycolate. However, the relative contribution of Hyp metabolism to endogenous oxalate and glycolate synthesis is not known.Methods To define this contribution, we performed primed, continuous, intravenous infusions of the stable isotope [15N,13C5]-Hyp in nine healthy subjects and 19 individuals with PH and quantified the levels of urinary 13C2-oxalate and 13C2-glycolate formed using ion chromatography coupled to mass detection.Results The total urinary oxalate-to-creatinine ratio during the infusion was 73.1, 70.8, 47.0, and 10.6 mg oxalate/g creatinine in subjects with PH1, PH2, and PH3 and controls, respectively. Hyp metabolism accounted for 12.8, 32.9, and 14.8 mg oxalate/g creatinine in subjects with PH1, PH2, and PH3, respectively, compared with 1.6 mg oxalate/g creatinine in controls. The contribution of Hyp to urinary oxalate was 15% in controls and 18%, 47%, and 33% in subjects with PH1, PH2, and PH3, respectively. The contribution of Hyp to urinary glycolate was 57% in controls, 30% in subjects with PH1, and <13% in subjects with PH2 or PH3.Conclusions Hyp metabolism differs among PH types and is a major source of oxalate synthesis in individuals with PH2 and PH3. In patients with PH1, who have the highest urinary excretion of oxalate, the major sources of oxalate remain to be identified. PMID- 29588433 TI - Sexual Dysfunction in Patients with Antidepressant-treated Anxiety or Depressive Disorders: a Pragmatic Multivariable Longitudinal Study. AB - OBJECTIVE: To investigate early evolution, tolerability, and predictors of antidepressant-emergent sexual dysfunction in patients with anxiety or depressive disorder. METHODS: Patients with anxiety or depressive disorders who were prescribed antidepressant monotherapy (mirtazapine, sertraline, desvenlafaxine, escitalopram, or fluoxetine) at the discretion of the treating clinician were recruited from July 2012 to June 2014 from a hospital outpatient service. All were free of psychotropic medication for least 1 month. Sexual function was assessed at baseline, week 2, and week 6 using the Psychotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ). A PRSexDQ score of >=2 was considered to indicate sexual dysfunction. Sexual function was dichotomised to 'favourable' or 'impaired'. RESULTS: Of 230 patients recruited, 209 were assessed at baseline of whom 184 were assessed at week 2; of these, 154 were also assessed at week 6. At baseline, 138 (66%) of the 209 patients were diagnosed with depressive disorder and 71 (34%) with anxiety disorder; 29% of patients had sexual dysfunction (in any domain of PRSexDQ). By week 6, the percentage had increased to 41%, although the change in the mean PRSexDQ score was only marginal (from 1.04 at baseline to 1.55 at week 6). With regard to individual questionnaire items, by week 6, sexual desire improved, but erectile and ejaculatory function in men and orgasmic function in women worsened. Fluoxetine and sertraline were associated with impaired sexual function, whereas mirtazapine was associated with favourable sexual function. In a logistic regression analysis, at week 2, mirtazapine and desvenlafaxine were predictors of favourable sexual outcome, whereas fluoxetine and higher baseline PRSexDQ score were predictors of impaired sexual outcome. At week 6, mirtazapine remained a predictor of favourable sexual outcome, whereas fluoxetine, higher 2-week PRSexDQ score, and adequate dose were predictors of impaired sexual outcome. CONCLUSIONS: In patients with anxiety or depressive disorder, the risk of antidepressant-emergent sexual dysfunction at 6 weeks is low when drug doses are initially low with gradual up-titration. Baseline sexual dysfunction was independently associated with impaired sexual outcome. Men may be more likely than women to experience impaired sexual outcome. In patients with baseline sexual dysfunction, prescription of mirtazapine might be preferable to fluoxetine. PMID- 29588430 TI - An Engineered Complement Factor H Construct for Treatment of C3 Glomerulopathy. AB - Background C3 glomerulopathy (C3G) is associated with dysregulation of the alternative pathway of complement activation, and treatment options for C3G remain limited. Complement factor H (FH) is a potent regulator of the alternative pathway and might offer a solution, but the mass and complexity of FH makes generation of full-length FH far from trivial. We previously generated a mini-FH construct, with FH short consensus repeats 1-5 linked to repeats 18-20 (FH1-5^18 20), that was effective in experimental C3G. However, the serum t1/2 of FH1-5^18 20 was significantly shorter than that of serum-purified FH.Methods We introduced the oligomerization domain of human FH-related protein 1 (denoted by R1-2) at the carboxy or amino terminus of human FH1-5^18-20 to generate two homodimeric mini FH constructs (FHR1-2^1-5^18-20 and FH1-5^18-20^R1-2, respectively) in Chinese hamster ovary cells and tested these constructs using binding, fluid-phase, and erythrocyte lysis assays, followed by experiments in FH-deficient Cfh-/- mice.Results FHR1-2^1-5^18-20 and FH1-5^18-20^R1-2 homodimerized in solution and displayed avid binding profiles on clustered C3b surfaces, particularly FHR1-2^1 5^18-20 Each construct was >10-fold more effective than FH at inhibiting cell surface complement activity in vitro and restricted glomerular basement membrane C3 deposition in vivo significantly better than FH or FH1-5^18-20 FH1-5^18-20^R1 2 had a C3 breakdown fragment binding profile similar to that of FH, a >5-fold increase in serum t1/2 compared with that of FH1-5^18-20, and significantly better retention in the kidney than FH or FH1-5^18-20Conclusions FH1-5^18-20^R1-2 may have utility as a treatment option for C3G or other complement-mediated diseases.

AB - Background/Aims: This study aimed to describe the health-related quality of life (HRQoL) outcomes for Korean chronic hepatitis C patients and to investigate the impact of patient and virus-related factors on HRQoL. Methods: HRQoL was assessed in 235 hepatitis C virus (HCV)-infected patients from seven nationwide tertiary hospital, including those with liver cirrhosis and hepatocellular carcinoma (HCC), using the Shor-Form 36 (SF-36) version 2 and the European quality of life questionnaire-5 dimensions (EQ-5D-3L). Results: The SF-36 physical (48.8+/-8.3) and mental (46.2+/-11.7) component summary scores of the HCV-infected patients were below normal limits. Of the eight domains, general health, vitality, and mental health tended to show low scores. Patients with decompensated cirrhosis had the lowest HRQoL, while HCC and chronic hepatitis patients had similar HRQoL results. The EQ-5D index was low (0.848+/-0.145) in the HCV infected patients. Multivariable analysis showed age <=65 years, high monthly family income (>$2,641), low comorbidity score, and sustained virologic response (SVR) were independently associated with favorable HRQoL. Conclusions: HRQoL in Korean patients with chronic HCV infection was low and was affected by cirrhosis severity, SVR, and comorbidity as well as income, which had the strongest effect. Therefore, HRQoL may be improved by antiviral therapy with reasonable costs to prevent cirrhosis progression. PMID- 29588437 TI - Time-gated scintillator imaging for real-time optical surface dosimetry in total skin electron therapy. AB - The purpose of this study was to measure surface dose by remote time-gated imaging of plastic scintillators. A novel technique for time-gated, intensified camera imaging of scintillator emission was demonstrated, and key parameters influencing the signal were analyzed, including distance, angle and thickness. A set of scintillator samples was calibrated by using thermo-luminescence detector response as reference. Examples of use in total skin electron therapy are described. The data showed excellent room light rejection (signal-to-noise ratio of scintillation SNR ~ 470), ideal scintillation dose response linearity, and 2% dose rate error. Individual sample scintillation response varied by 7% due to sample preparation. Inverse square distance dependence correction and lens throughput error (8% per meter) correction were needed. At scintillator-to-source angle and observation angle <50 degrees , the radiant energy fluence error was smaller than 1%. The achieved standard error of the scintillator cumulative dose measurement compared to the TLD dose was 5%. The results from this proof-of concept study documented the first use of small scintillator targets for remote surface dosimetry in ambient room lighting. The measured dose accuracy renders our method to be comparable to thermo-luminescent detector dosimetry, with the ultimate realization of accuracy likely to be better than shown here. Once optimized, this approach to remote dosimetry may substantially reduce the time and effort required for surface dosimetry. PMID- 29588436 TI - Long-Term Clinical Outcomes of Endoscopic Submucosal Dissection in Patients with Early Gastric Cancer: A Prospective Multicenter Cohort Study. AB - Background/Aims: Endoscopic submucosal dissection (ESD) has been regarded as a curative treatment for early gastric cancer (EGC) in indicated cases. The aim of this study was to evaluate the nationwide long-term clinical outcomes of ESD for EGC in Korea. Methods: A prospective multicenter cohort study was performed to evaluate the long-term efficacy of ESD for EGC within pre-defined indications at 12 institutes in Korea. The cases that met the expanded criteria upon pathological review after ESD were followed for 5 years. The primary outcome was 5-year disease specific free survival. Results: Six hundred ninety-seven patients with 722 EGCs treated with ESD were prospectively enrolled and followed for 5 years. Complete resection was achieved in 81.3% of the cases, and curative resection was achieved in 86.1%. During the 5-year follow-up, the overall survival rate was 96.6%, and the disease specific free survival rate was 90.6%. Local recurrence developed in 0.9%, and metachronous tumor development occurred in 7.8%; both conditions were treated by endoscopic or surgical treatment. Distant metastasis developed in 0.5% during follow-up. Conclusions: ESD showed excellent long-term clinical outcomes and can be accepted as a curative treatment for patients with EGC who meet the expanded criteria in final pathology studies.

AB - As an important extrinsic source of mortality, harvest should select for fast reproduction and accelerated life histories. However, if vulnerability to harvest depends upon female reproductive status, patterns of selectivity could diverge and favor alternative reproductive behaviors. Here, using more than 20 years of detailed data on survival and reproduction in a hunted large carnivore population, we show that protecting females with dependent young, a widespread hunting regulation, provides a survival benefit to females providing longer maternal care. This survival gain compensates for the females' reduced reproductive output, especially at high hunting pressure, where the fitness benefit of prolonged periods of maternal care outweighs that of shorter maternal care. Our study shows that hunting regulation can indirectly promote slower life histories by modulating the fitness benefit of maternal care tactics. We provide empirical evidence that harvest regulation can induce artificial selection on female life history traits and affect demographic processes. PMID- 29588443 TI - GS9 acts as a transcriptional activator to regulate rice grain shape and appearance quality. AB - Identification of grain shape determining genes can facilitate breeding of rice cultivars with optimal grain shape and appearance quality. Here, we identify GS9 (Grain Shape Gene on Chromosome 9) gene by map-based cloning. The gs9 null mutant has slender grains, while overexpression GS9 results in round grains. GS9 encodes a protein without known conserved functional domain. It regulates grain shape by altering cell division. The interaction of GS9 and ovate family proteins OsOFP14 and OsOFP8 is modulated by OsGSK2 kinase, a key regulator of the brassinosteroids signaling pathway. Genetic interaction analysis reveals that GS9 functions independently from other previously identified grain size genes. Introducing the gs9 allele into elite rice cultivars significantly improves grain shape and appearance quality. It suggests potential application of gs9, alone or in combination with other grain size determining genes, in breeding of rice varieties with optimized grain shape. PMID- 29588444 TI - Pre-Columbian earth-builders settled along the entire southern rim of the Amazon. AB - The discovery of large geometrical earthworks in interfluvial settings of southern Amazonia has challenged the idea that Pre-Columbian populations were concentrated along the major floodplains. However, a spatial gap in the archaeological record of the Amazon has limited the assessment of the territorial extent of earth-builders. Here, we report the discovery of Pre-Columbian ditched enclosures in the Tapajos headwaters. The results show that an 1800 km stretch of southern Amazonia was occupied by earth-building cultures living in fortified villages ~Cal AD 1250-1500. We model earthwork distribution in this broad region using recorded sites, with environmental and terrain variables as predictors, estimating that earthworks will be found over ~400,000 km2 of southern Amazonia. We conclude that the interfluves and minor tributaries of southern Amazonia sustained high population densities, calling for a re-evaluation of the role of this region for Pre-Columbian cultural developments and environmental impact.

AB - The rebinding kinetics of NO after photodissociation from microperoxidase (Mp-9) is studied in different solvent environments. In mixed glycerol/water (G/W) mixtures the dissociating ligand rebinds with a yield close to 1 due to the cavities formed by the solvent whereas in pure water the ligand can diffuse into the solvent after photodissociation. In the G/W mixture, only geminate rebinding on the sub-picosecond and 5 ps time scales was found and the rebinding fraction is unity which compares well with available experiments. Contrary to that, simulations in pure water find two time scales - ~10 ps and ~200 ps - indicating that both, geminate rebinding and rebinding after diffusion of NO in the surrounding water contribute. The rebinding fraction is around 0.63 within 1 ns which is in stark contrast with experiment. Including ions (Na and Cl) at 0.15 M concentration in water leads to rebinding kinetics tending to that in the glycerol/water mixture and yields agreement with experiments. The effect of temperature is also probed and found to be non-negligible. The present simulations suggest that NO rebinding in Mp is primarily driven by thermal fluctuations which is consistent with recent resonance Raman spectroscopy experiments and simulations on MbNO.

AB - Recent advances in two-dimensional dopant profiling in the scanning electron microscope have enabled a high throughput, non-contact process diagnostics and failure analysis solution for integrated device manufacturing. The routine (electro)chemical etch processes to obtain contamination-free, hydrogen terminated silicon surfaces is industrially important in ULSI microfabrication, though doping contrast, which is the basis for quantitative dopant profiling, will be strongly altered. We show herein that ammonium-fluoride treatment not only enabled doping contrast to be differentiated mainly by surface band-bending, but it enhanced the quality of linear quantitative calibration through simple univariate analysis for SE energies as low as 1 eV. Energy-filtering measurements reveal that the linear analytical model broached in the literature (c.f. Kazemian et al., 2006 and Kazemian et al., 2007) is likely to be inadequate to determine the surface potential across semiconductor p-n junctions without suitable deconvolution methods. Nevertheless, quantification trends suggest that energy filtering may not be crucial if patch fields and contamination are absolutely suppressed by the appropriate edge termination and passivation. PMID- 29588447 TI - Enhancing the recovery of a temporal sequence of images using joint deconvolution. AB - In this work, we address the reconstruction of spatial patterns that are encoded in light fields associated with a series of light pulses emitted by a laser source and imaged using photon-counting cameras, with an intrinsic response significantly longer than the pulse delay. Adopting a Bayesian approach, we propose and demonstrate experimentally a novel joint temporal deconvolution algorithm taking advantage of the fact that single pulses are observed simultaneously by different pixels. Using an intensified CCD camera with a 1000 ps gate, stepped with 10-ps increments, we show the ability to resolve images that are separated by a 10-ps delay, four time better compared to standard deconvolution techniques.

AB - Energy production from biomass is one of the adopted strategies in different European countries to limit global warming to within the 1.5-2 degrees targets after the 2015 UN climate agreement. This will motivate enhanced forest harvest rates and whole tree harvest to supply the increasing biomass demand. Negative nutrient budgets for certain timberland areas where geogenic nutrient supply cannot cope with harvesting rates will be one consequence. A spatially explicit analysis for a U.S. timberland area of 33,570 km2 reveals that for a minimum nutrient loss and supply scenario, negative nutrient budgets occur in 17, 20, 16, and almost 94% of the studied areas for Ca, K, Mg, and P, respectively. For a maximum nutrient loss (considering intensive harvesting) and supply assumptions, the affected areas increase to 50, 57, 45 and 96% for Ca, K, Mg, and P, respectively. In general, atmospheric nutrient deposition is of minor importance for the high weathering supply cases. Increasing global woody biomass demand may cause additional pressure on forested ecosystems, enlarging negative nutrient budget areas. If woody biomass demand rises, strategies to counterbalance nutrient gaps might be needed, for example, by preparing harvested areas with rock products, designed to replenish growth limiting nutrients, and/or implementing forest management strategies to minimize nutrient export. PMID- 29588450 TI - Reducing electric-field-enhancement in metal-dielectric grating by designing grating with asymmetric ridge. AB - Diffraction gratings are an essential optical component of high-power, short pulse lasers. The maximum output of high-power pulsed lasers is always determined by laser resistance of gratings and this resistance is strongly dependent on the local near electric field intensity in the grating structure. We presented a novel method of reducing electric-field-enhancement in metal-dielectric grating by designing asymmetric grating ridge while maintaining high diffraction performance. Compared with the common isosceles trapezoidal grating, the grating with asymmetric ridge got a 0.04% reduction of diffraction efficiency in TE polarization at 1053 nm incident wavelength but a 21.3% reduction of maximal electric-field-enhancement in grating structure. This method can be applied to any surface-relief gratings to reduce the electric-field-enhancement for improving the laser induced damage threshold (LIDT) of grating and supporting the grating-based chirped pulse amplification (CPA) system to develop into higher peak-power levels. PMID- 29588449 TI - Confirmation of a metastasis-specific microRNA signature in primary colon cancer. AB - The identification of patients with high-risk stage II colon cancer who may benefit from adjuvant therapy may allow the clinical approach to be tailored for these patients based on an understanding of tumour biology. MicroRNAs have been proposed as markers of the prognosis or treatment response in colorectal cancer. Recently, a 2-microRNA signature (let-7i and miR-10b) was proposed to identify colorectal cancer patients at risk of developing distant metastasis. We assessed the prognostic value of this signature and additional candidate microRNAs in an independent, clinically well-defined, prospectively collected cohort of primary colon cancer patients including stage I-II colon cancer without and stage III colon cancer with adjuvant treatment. The 2-microRNA signature specifically predicted hepatic recurrence in the stage I-II group, but not the overall ability to develop distant metastasis. The addition of miR-30b to the 2-microRNA signature allowed the prediction of both distant metastasis and hepatic recurrence in patients with stage I-II colon cancer who did not receive adjuvant chemotherapy. Available gene expression data allowed us to associate miR-30b expression with axon guidance and let-7i expression with cell adhesion, migration, and motility. PMID- 29588451 TI - Identification of the functional pathways altered by placental cell exposure to high glucose: lessons from the transcript and metabolite interactome. AB - The specific consequences of hyperglycaemia on placental metabolism and function are incompletely understood but likely contribute to poor pregnancy outcomes associated with diabetes mellitus (DM). This study aimed to identify the functional biochemical pathways perturbed by placental exposure to high glucose levels through integrative analysis of the trophoblast transcriptome and metabolome. The human trophoblast cell line, BeWo, was cultured in 5 or 25 mM glucose, as a model of the placenta in DM. Transcriptomic analysis using microarrays, demonstrated 5632 differentially expressed gene transcripts (>=+/- 1.3 fold change (FC)) following exposure to high glucose. These genes were used to generate interactome models of transcript response using BioGRID (non-inferred network: 2500 nodes (genes) and 10541 protein-protein interactions). Ultra performance-liquid chromatography-mass spectrometry (MS) and gas chromatography MS analysis of intracellular extracts and culture medium were used to assess the response of metabolite profiles to high glucose concentration. The interactions of altered genes and metabolites were assessed using the MetScape interactome database, resulting in an integrated model of systemic transcriptome (2969 genes) and metabolome (41 metabolites) response within placental cells exposed to high glucose. The functional pathways which demonstrated significant change in response to high glucose included fatty acid beta-oxidation, phospholipid metabolism and phosphatidylinositol phosphate signalling.

AB - Mosquito control with bednets, residual sprays or fumigation remains the most effective tool for preventing vector-borne diseases such as malaria, dengue and Zika, though there are no widely used entomological methods for directly assessing its efficacy. Mosquito age is the most informative metric for evaluating interventions that kill adult mosquitoes but there is no simple or reliable way of measuring it in the field. Near-Infrared Spectroscopy (NIRS) has been shown to be a promising, high-throughput method that can estimate the age of mosquitoes. Currently the ability of NIRS to measure mosquito age is biased, and has relatively high individual mosquito measurement error, though its capacity to rigorously monitor mosquito populations in the field has never been assessed. In this study, we use machine learning methods from the chemometric literature to generate more accurate, unbiased estimates of individual mosquito age. These unbiased estimates produce precise population-level measurements, which are relatively insensitive to further increases in NIRS accuracy when feasible numbers of mosquitoes are sampled. The utility of NIRS to directly measure the impact of pyrethroid resistance on mosquito control is illustrated, showing how the technology has potential as a highly valuable tool for directly assessing the efficacy of mosquito control interventions. PMID- 29588453 TI - Erythrocyte's aging in microgravity highlights how environmental stimuli shape metabolism and morphology. AB - The determination of the function of cells in zero-gravity conditions is a subject of interest in many different research fields. Due to their metabolic unicity, the characterization of the behaviour of erythrocytes maintained in prolonged microgravity conditions is of particular importance. Here, we used a 3D clinostat to assess the microgravity-induced modifications of the structure and function of these cells, by investigating how they translate these peculiar mechanical stimuli into modifications, with potential clinical interest, of the biochemical pathways and the aging processes. We compared the erythrocyte's structural parameters and selected metabolic indicators that are characteristic of the aging in microgravity and standard static incubation conditions. The results suggest that, at first, human erythrocytes react to external stimuli by adapting their metabolic patterns and the rate of consumption of the cell resources. On longer timeframes, the cells translate even small differences in the environment mechanical solicitations into structural and morphologic features, leading to distinctive morphological patterns of aging. PMID- 29588454 TI - The effect of nitrogen lone-pair interaction on the conduction in a single molecule junction with amine-Au bonding. AB - We have applied our previously developed three-dimensional dynamic probe method to analyze the conductance in a Au-/1,4-benzenediamine (BDA)/Au single molecule junction. This structure is a typically used example to demonstrate the high performance of the break junction (BJ) method for measuring conductance with small variations, however, details of the interaction of the nitrogen (N) lone pair in the amine group with a Au electrode, which is considered to have a fundamental role in determining the conductance of the single molecule junction with the amine, have not yet been clarified and still remain an important issue to be resolved. In this study, we have succeeded, for the first time, in observing the site-dependent change in conductance of this system while the molecular conformation was accurately controlled, and the results were well reproduced by a simulation taking account of the effect of the N lone-pair in an amine bonding with a Au electrode. PMID- 29588455 TI - Proteomic and bioinformatic pipeline to screen the ligands of S. pneumoniae interacting with human brain microvascular endothelial cells. AB - The mechanisms by which Streptococcus pneumoniae penetrates the blood-brain barrier (BBB), reach the CNS and causes meningitis are not fully understood. Adhesion of bacterial cells on the brain microvascular endothelial cells (BMECs), mediated through protein-protein interactions, is one of the crucial steps in translocation of bacteria across BBB. In this work, we proposed a systematic workflow for identification of cell wall associated ligands of pneumococcus that might adhere to the human BMECs. The proteome of S. pneumoniae was biotinylated and incubated with BMECs. Interacting proteins were recovered by affinity purification and identified by data independent acquisition (DIA). A total of 44 proteins were identified from which 22 were found to be surface-exposed. Based on the subcellular location, ontology, protein interactive analysis and literature review, five ligands (adhesion lipoprotein, endo-beta-N-acetylglucosaminidase, PhtA and two hypothetical proteins, Spr0777 and Spr1730) were selected to validate experimentally (ELISA and immunocytochemistry) the ligand-BMECs interaction. In this study, we proposed a high-throughput approach to generate a dataset of plausible bacterial ligands followed by systematic bioinformatics pipeline to categorize the protein candidates for experimental validation. The approach proposed here could contribute in the fast and reliable screening of ligands that interact with host cells. PMID- 29588456 TI - Inhalational Anesthetics Induce Neuronal Protein Aggregation and Affect ER Trafficking. AB - Anesthetic agents have been implicated in the causation of neurological and cognitive deficits after surgery, the exacerbation of chronic neurodegenerative disease, and were recently reported to promote the onset of the neurologic respiratory disease Congenital Central Hypoventilation Syndrome (CCHS), related to misfolding of the transcription factor Phox2B. To study how anesthetic agents could affect neuronal function through alterations to protein folding, we created neuronal cell models emulating the graded disease severity of CCHS. We found that the gas anesthetic isoflurane and the opiate morphine potentiated aggregation and mislocalization of Phox2B variants, similar to that seen in CCHS, and observed transcript and protein level changes consistent with activation of the endoplasmic reticulum (ER) unfolded protein response. Attenuation of ER stress pathways did not result in a correction of Phox2B misfolding, indicating a primary effect of isoflurane on protein structure. We also observed that isoflurane hindered the folding and activity of proteins that rely heavily on ER function, like the CFTR channel. Our results show how anesthetic drugs can alter protein folding and induce ER stress, indicating a mechanism by which these agents may affect neuronal function after surgery. PMID- 29588457 TI - Efficacy and safety of boosted darunavir-based antiretroviral therapy in HIV-1 positive patients: results from a meta-analysis of clinical trials. AB - Darunavir/ritonavir (DRV/r) is a second-generation protease inhibitor used in treatment-naive and -experienced HIV-positive adult patients. To evaluate efficacy and safety in these patient settings, we performed a meta-analysis of randomized controlled trials. We considered eight studies involving 4240 antiretroviral treatment (ART)-naive patients and 14 studies involving 2684 ART experienced patients. Regarding efficacy in the ART-naive patients, the virological response rate was not significantly different between DRV/r and the comparator. For the ART-experienced failing patients, the virological response rate was significantly higher with DRV/r than with the comparator (RR 1.45, 95% CI: 1.01-2.08); conversely, no significant differences were found between the treatment-experienced and virologically controlled DRV/r and comparator groups. Regarding safety, the discontinuation rates due to adverse events (AEs) and DRV/r related serious adverse events (SAEs) did not significantly differ from the rates in the comparator group (RR 0.84, 95% CI: 0.59-1.19 and RR 0.78, 95% CI: 0.57 1.05, respectively). Our meta-analysis indicated that DRV/r-based regimens were effective and tolerable for both types of patients, which was consistent with published data. PMID- 29588458 TI - Personalised drug repositioning for Clear Cell Renal Cell Carcinoma using gene expression. AB - Reversal of cancer gene expression is predictive of therapeutic potential and can be used to find new indications for existing drugs (drug repositioning). Gene expression reversal potential is currently calculated, in almost all studies, by pre-aggregating all tumour samples into a single group signature or a limited number of molecular subtype signatures. Here, we investigate whether drug repositioning based on individual tumour sample gene expression signatures outperforms the use of tumour group and subtype signatures. The tumour signatures were created using 534 tumour samples and 72 matched normal samples from 530 clear cell renal cell carcinoma (ccRCC) patients. More than 20,000 drug signatures were extracted from the CMAP and LINCS databases. We show that negative enrichment of individual tumour samples correlated (Spearman's rho = 0.15) much better with the amount of differentially expressed genes in drug signatures than with the tumour group signature (Rho = 0.08) and the 4 tumour subtype signatures (Rho 0.036-0.11). Targeted drugs used against ccRCC, such as sirolimus and temsirolimus, which could not be identified with the pre-aggregated tumour signatures could be recovered using individual sample analysis. Thus, drug repositioning can be personalized by taking into account the gene expression profile of the individual's tumour sample. PMID- 29588459 TI - A unified framework for modelling sediment fate from source to sink and its interactions with reef systems over geological times. AB - Understanding the effects of climatic variability on sediment dynamics is hindered by limited ability of current models to simulate long-term evolution of sediment transfer from source to sink and associated morphological changes. We present a new approach based on a reduced-complexity model which computes over geological time: sediment transport from landmasses to coasts, reworking of marine sediments by longshore currents, and development of coral reef systems. Our framework links together the main sedimentary processes driving mixed siliciclastic-carbonate system dynamics. It offers a methodology for objective and quantitative sediment fate estimations over regional and millennial time scales. A simulation of the Holocene evolution of the Great Barrier Reef shows: (1) how high sediment loads from catchments erosion prevented coral growth during the early transgression phase and favoured sediment gravity-flows in the deepest parts of the northern region basin floor (prior to 8 ka before present (BP)); (2) how the fine balance between climate, sea-level, and margin physiography enabled coral reefs to thrive under limited shelf sedimentation rates after ~6 ka BP; and, (3) how since 3 ka BP, with the decrease of accommodation space, reduced of vertical growth led to the lateral extension of reefs consistent with available observational data. PMID- 29588460 TI - Investigation of the Oxidation Behaviour of Ti and Al in Inconel 718 Superalloy During Electroslag Remelting. AB - In the current study, the thermodynamics of the slag-metal equilibrium reaction between Inconel 718 Ni-based alloy and CaF2-CaO-Al2O3-MgO-TiO2 electroslag remelting (ESR)-type slags were systematically investigated in the temperature range from 1773 to 1973 K (1500 to 1700 degrees C). The equilibrium Al content increased with increasing temperature, whereas the equilibrium Ti content decreased with increasing temperature at a fixed slag composition. The important factors for controlling the oxidation of Al and Ti in the Inconel 718 superalloy were TiO2 > Al2O3 > CaO > CaF2 > MgO in ESR-type slag and Al > Ti in a consumable electrode. The conventional method of sampling by means of a quartz tube could result in contamination of the molten metal and changes in the size of the "special reaction interface". Therefore, a novel method was used in the present study to investigate the slag-metal reaction kinetics to accurately obtain the kinetic parameters. The mass transfer coefficient was determined by coupling with the kinetic model derived from the assumption that the reaction rate ([Al] + (TiO2) = [Ti] + (Al2O3)) was controlled by the mass transfer of [Ti], [Al], (TiO2) and (Al2O3) in the boundary layer, respectively. PMID- 29588462 TI - Spin density wave instability in a ferromagnet. AB - Due to its cooperative nature, magnetic ordering involves a complex interplay between spin, charge, and lattice degrees of freedom, which can lead to strong competition between magnetic states. Binary Fe3Ga4 is one such material that exhibits competing orders having a ferromagnetic (FM) ground state, an antiferromagnetic (AFM) behavior at intermediate temperatures, and a conspicuous re-entrance of the FM state at high temperature. Through a combination of neutron diffraction experiments and simulations, we have discovered that the AFM state is an incommensurate spin-density wave (ISDW) ordering generated by nesting in the spin polarized Fermi surface. These two magnetic states, FM and ISDW, are seldom observed in the same material without application of a polarizing magnetic field. To date, this unusual mechanism has never been observed and its elemental origins could have far reaching implications in many other magnetic systems that contain strong competition between these types of magnetic order. Furthermore, the competition between magnetic states results in a susceptibility to external perturbations allowing the magnetic transitions in Fe3Ga4 to be controlled via temperature, magnetic field, disorder, and pressure. Thus, Fe3Ga4 has potential for application in novel magnetic memory devices, such as the magnetic components of tunneling magnetoresistance spintronics devices. PMID- 29588461 TI - Diffusion tensor tractography of the mammillothalamic tract in the human brain using a high spatial resolution DTI technique. AB - The mammillary bodies as part of the hypothalamic nuclei are in the central limbic circuitry of the human brain. The mammillary bodies are shown to be directly or indirectly connected to the amygdala, hippocampus, and thalami as the major gray matter structures of the human limbic system. Although it is not primarily considered as part of the human limbic system, the thalamus is shown to be involved in many limbic functions of the human brain. The major direct connection of the thalami with the hypothalamic nuclei is known to be through the mammillothalamic tract. Given the crucial role of the mammillothalamic tracts in memory functions, diffusion tensor imaging may be helpful in better visualizing the surgical anatomy of this pathway noninvasively. This study aimed to investigate the utility of high spatial resolution diffusion tensor tractography for mapping the trajectory of the mammillothalamic tract in the human brain. Fifteen healthy adults were studied after obtaining written informed consent. We used high spatial resolution diffusion tensor imaging data at 3.0 T. We delineated, for the first time, the detailed trajectory of the mammillothalamic tract of the human brain using deterministic diffusion tensor tractography. PMID- 29588464 TI - Rydberg interaction induced enhanced excitation in thermal atomic vapor. AB - We present the experimental demonstration of interaction induced enhancement in Rydberg excitation or Rydberg anti-blockade in thermal atomic vapor. We have used optical heterodyne detection technique to measure Rydberg population due to two photon excitation to the Rydberg state. The anti-blockade peak which doesn't satisfy the two-photon resonant condition is observed along with the usual two photon resonant peak which can't be explained using the model with non interacting three-level atomic system. A model involving two interacting atoms is formulated for thermal atomic vapor using the dressed states of three-level atomic system to explain the experimental observations. A non-linear dependence of vapor density is observed for the anti-blockade peak which also increases with increase in principal quantum number of the Rydberg state. A good agreement is found between the experimental observations and the proposed interacting model. Our result implies possible applications towards quantum logic gates using Rydberg anti-blockade in thermal atomic vapor. PMID- 29588463 TI - Combining targeted panel-based resequencing and copy-number variation analysis for the diagnosis of inherited syndromic retinopathies and associated ciliopathies. AB - Inherited syndromic retinopathies are a highly heterogeneous group of diseases that involve retinal anomalies and systemic manifestations. They include retinal ciliopathies, other well-defined clinical syndromes presenting with retinal alterations and cases of non-specific multisystemic diseases. The heterogeneity of these conditions makes molecular and clinical characterization of patients challenging in daily clinical practice. We explored the capacity of targeted resequencing and copy-number variation analysis to improve diagnosis of a heterogeneous cohort of 47 patients mainly comprising atypical cases that did not clearly fit a specific clinical diagnosis. Thirty-three likely pathogenic variants were identified in 18 genes (ABCC6, ALMS1, BBS1, BBS2, BBS12, CEP41, CEP290, IFT172, IFT27, MKKS, MYO7A, OTX2, PDZD7, PEX1, RPGRIP1, USH2A, VPS13B, and WDPCP). Molecular findings and additional clinical reassessments made it possible to accurately characterize 14 probands (30% of the total). Notably, clinical refinement of complex phenotypes was achieved in 4 cases, including 2 de novo OTX2-related syndromes, a novel phenotypic association for the ciliary CEP41 gene, and the co-existence of biallelic USH2A variants and a Koolen-de-Vries syndrome-related 17q21.31 microdeletion. We demonstrate that combining next generation sequencing and CNV analysis is a comprehensive and useful approach to unravel the extensive phenotypic and genotypic complexity of inherited syndromic retinopathies. PMID- 29588465 TI - MEF2A regulates mGluR-dependent AMPA receptor trafficking independently of Arc/Arg3.1. AB - Differential trafficking of AMPA receptors (AMPARs) to and from the postsynaptic membrane is a key determinant of the strength of excitatory neurotransmission, and is thought to underlie learning and memory. The transcription factor MEF2 is a negative regulator of memory in vivo, in part by regulating trafficking of the AMPAR subunit GluA2, but the molecular mechanisms behind this have not been established. Here we show, via knockdown of endogenous MEF2A in primary neuronal culture, that MEF2A is specifically required for Group I metabotropic glutamate receptor (mGluR)-mediated GluA2 internalisation, but does not regulate AMPAR expression or trafficking under basal conditions. Furthermore, this process occurs independently of changes in expression of Arc/Arg3.1, a previously characterised MEF2 transcriptional target and mediator of mGluR-dependent long term depression. These data demonstrate a novel MEF2A-dependent mechanism for the regulation of activity-dependent AMPAR trafficking. PMID- 29588466 TI - Canagliflozin inhibits interleukin-1beta-stimulated cytokine and chemokine secretion in vascular endothelial cells by AMP-activated protein kinase-dependent and -independent mechanisms. AB - Recent clinical trials of the hypoglycaemic sodium-glucose co-transporter-2 (SGLT2) inhibitors, which inhibit renal glucose reabsorption, have reported beneficial cardiovascular outcomes. Whether SGLT2 inhibitors directly affect cardiovascular tissues, however, remains unclear. We have previously reported that the SGLT2 inhibitor canagliflozin activates AMP-activated protein kinase (AMPK) in immortalised cell lines and murine hepatocytes. As AMPK has anti inflammatory actions in vascular cells, we examined whether SGLT2 inhibitors attenuated inflammatory signalling in cultured human endothelial cells. Incubation with clinically-relevant concentrations of canagliflozin, but not empagliflozin or dapagliflozin activated AMPK and inhibited IL-1beta-stimulated adhesion of pro-monocytic U937 cells and secretion of IL-6 and monocyte chemoattractant protein-1 (MCP-1). Inhibition of MCP-1 secretion was attenuated by expression of dominant-negative AMPK and was mimicked by the direct AMPK activator, A769662. Stimulation of cells with either canagliflozin or A769662 had no effect on IL-1beta-stimulated cell surface levels of adhesion molecules or nuclear factor-kappaB signalling. Despite these identical effects of canagliflozin and A769662, IL-1beta-stimulated IL-6/MCP-1 mRNA was inhibited by canagliflozin, but not A769662, whereas IL-1beta-stimulated c-jun N-terminal kinase phosphorylation was inhibited by A769662, but not canagliflozin. These data indicate that clinically-relevant canagliflozin concentrations directly inhibit endothelial pro-inflammatory chemokine/cytokine secretion by AMPK dependent and -independent mechanisms without affecting early IL-1beta signalling. PMID- 29588467 TI - Intriguingly high thermal conductivity increment for CuO nanowires contained nanofluids with low viscosity. AB - Nanofluids offer the exciting new possibilities to enhance heat transfer performance. In this paper, experimental and theoretical investigations have been conducted to determine the effect of CuO nanowires on the thermal conductivity and viscosity of dimethicone based nanofluids. The CuO nanowires were prepared through a thermal oxidation method, and the analysis indicated that the as prepared CuO nanowires had high purity, monocrystalline with a monoclinic structure and large aspect ratio compared to CuO nanospheres. The experimental data show that the thermal conductivity of the nanofluids increases with the volume fraction of CuO nanowires or nanospheres, with a nearly linear relationship. For the nanofluid with the addition of 0.75 vol.% CuO nanowires, the thermal conductivity enhancement is up to 60.78%, which is much higher than that with spherical CuO nanoparticles. The nanofluids exhibit typical Newtonian behavior, and the measured viscosity of CuO nanowires contained nanofluids were found only 6.41% increment at the volume fraction of 0.75%. It is attractive in enhanced heat transfer for application. The thermal conductivity and viscosity of CuO nanofluids were further calculated and discussed by comparing our experimental results with the classic theoretical models. The mechanisms of thermal conductivity and viscosity about nanofluids were also discussed in detail. PMID- 29588468 TI - Ras hyperactivation versus overexpression: Lessons from Ras dynamics in Candida albicans. AB - Ras signaling in response to environmental cues is critical for cellular morphogenesis in eukaryotes. This signaling is tightly regulated and its activation involves multiple players. Sometimes Ras signaling may be hyperactivated. In C. albicans, a human pathogenic fungus, we demonstrate that dynamics of hyperactivated Ras1 (Ras1G13V or Ras1 in Hsp90 deficient strains) can be reliably differentiated from that of normal Ras1 at (near) single molecule level using fluorescence correlation spectroscopy (FCS). Ras1 hyperactivation results in significantly slower dynamics due to actin polymerization. Activating actin polymerization by jasplakinolide can produce hyperactivated Ras1 dynamics. In a sterol-deficient hyperfilamentous GPI mutant of C. albicans too, Ras1 hyperactivation results from Hsp90 downregulation and causes actin polymerization. Hyperactivated Ras1 co-localizes with G-actin at the plasma membrane rather than with F-actin. Depolymerizing actin with cytochalasin D results in faster Ras1 dynamics in these and other strains that show Ras1 hyperactivation. Further, ergosterol does not influence Ras1 dynamics. PMID- 29588469 TI - Material Synthesis and Device Aspects of Monolayer Tungsten Diselenide. AB - In this paper, we investigate the synthesis of WSe2 by chemical vapor deposition and study the current transport and device scaling of monolayer WSe2. We found that the device characteristics of the back-gated WSe2 transistors with thick oxides are very sensitive to the applied drain bias, especially for transistors in the sub-micrometer regime. The threshold voltage, subthreshold swing, and extracted field-effect mobility vary with the applied drain bias. The output characteristics in the long-channel transistors show ohmic-like behavior, while that in the short-channel transistors show Schottky-like behavior. Our investigation reveals that these phenomena are caused by the drain-induced barrier lowering (short-channel effect). For back-gated WSe2 transistors with 280 nm oxide, the short-channel effect appears when the channel length is shorter than 0.4 um. This extremely long electrostatic scaling length is due to the thick back-gate oxides. In addition, we also found that the hydrogen flow rate and the amount of WO3 precursor play an important role in the morphology of the WSe2. The hole mobility of the monolayer WSe2 is limited by Columbic scattering below 250 K, while it is limited by phonon scattering above 250 K. These findings are very important for the synthesis of WSe2 and accurate characterization of the electronic devices based on 2D materials. PMID- 29588470 TI - Soluble epoxide hydrolase inhibition decreases reperfusion injury after focal cerebral ischemia. AB - Epoxyeicosatrienoic acids (EETs) are produced by cytochrome P450 epoxygenases from arachidonic acid, and their rapid metabolism is mainly through soluble epoxide hydrolase (sEH). EETs exert vasodilatory, anti-inflammatory, anti apoptotic, and pro-angiogenic effects. Administration of sEH inhibitors before or at the onset of stroke is protective, but the effects of post-treatment at reperfusion, when inflammation is augmented, has not been as well studied. We tested the hypothesis that 1-Trifluoromethoxyphenyl-3-(1-propionylpiperidin-4 yl)urea (TPPU), a potent and highly selective sEH inhibitor, suppresses inflammation and protects the brain when administered at reperfusion. Vehicle or 1 mg/kg TPPU was administered at reperfusion after 90 minutes of focal ischemia and again 24 hours later. Protein expression and activity of sEH increased after reperfusion and activity was decreased by TPPU administration. TPPU decreased infarct volume by 50%, reduced neurologic deficits and improved performance on sensorimotor tasks. Furthermore, TPPU significantly lowered the mRNA expression of interleukin-1beta by 3.5-fold and tumor necrosis factor-alpha by 2.2-fold, increased transforming growth factor-beta mRNA by 1.8-fold, and augmented immunostaining of vascular endothelial growth factor in peri-infarct cortex. Thus, inhibition of sEH at reperfusion significantly reduces infarction and improves sensorimotor function, possibly by suppressing early proinflammatory cytokines and promoting reparative cytokines and growth factors. PMID- 29588471 TI - Discovery of a highly selective JAK3 inhibitor for the treatment of rheumatoid arthritis. AB - Janus tyrosine kinase 3 (JAK3) is expressed in lymphoid cells and is involved in the signalling of T cell functions. The development of a selective JAK3 inhibitor has been shown to have a potential benefit in the treatment of autoimmune disorders. In this article, we developed the 4-aminopiperidine-based compound RB1, which was highly selective for JAK3 inhibition, with an IC50 of value of 40 nM, but did not inhibit JAK1, JAK2 or tyrosine kinase 2 (TYK2) at concentrations up to 5 uM. Furthermore, RB1 also exhibited favourable selectivity against a panel of representative kinases. In a battery of cytokine-stimulated cell-based assays, this potent inhibitor of JAK3 activity with good selectivity against other kinases could potently inhibit JAK3 activity over the activity of JAK1 or JAK2 (over at least 100-fold). A combination of liquid chromatography-mass spectrometry (LC-MS) experiments validated that RB1 covalently modified the unique cysteine 909 residue in JAK3. In vivo, RB1 exerted significantly improved pathology in the joints of a collagen-induced arthritis mouse model. The reasonable pharmacokinetics properties (F = 72.52%, T1/2 = 14.6 h) and favourable results of toxicology experiments (LD50 > 2 g/kg) suggest that RB1 has the potential to be an efficacious treatment for RA.

AB - : Osteoarthritis (OA) is a common musculoskeletal disorder and occur in different patterns. However, its impact on long-term all-cause-mortality is inconclusive. STUDY AIMS: Investigate 20-year all-cause-mortality in patients with hip/knee arthroplasty (recruited 1995/1996, N = 809) from the Ulm Osteoarthritis Study cohort, in comparison to general population. Furthermore, to enlighten the triangle between baseline life-style and cardio-metabolic risk factors, phenotypic OA-patterns (laterality, generalization, cause) and all-cause mortality. Mortality was assessed during 20 years follow-up. Standardized mortality ratios (SMR), adjusted odds ratios and hazard ratios (aHR) were calculated. After five years cohort-mortality was reduced compared to the general population, however 20 years later assimilated (SMR = 1.11; 95%-CI 0.73-1.49). OA patterns were associated with age, cholesterol, and overweight/obesity. In comparison to primary OA decreased mortality was observed for patients with secondary OA (aHR = 0.76; 95%-CI 0.61-0.95) adjusted for age, smoking, overweight/obesity, diabetes, hypertension, cardiac insufficiency, uric acid, and lower cholesterol. There was no increased mortality in patients after 20 years follow-up compared to general population. Significantly decreased mortality in secondary compared to primary OA suggests a subtype-specific involvement of systemic co-factors in determination of all-cause-mortality. Because cardio metabolic risk factors were associated with increased risk of bilateral OA and lower long-term survival, those risk factors should be consequently targeted in OA-patients. PMID- 29588473 TI - Spatial-temporal profiling of prodiginines and serratamolides produced by endophytic Serratia marcescens harbored in Maytenus serrata. AB - An endophytic bacterium, Serratia marcescens MSRBB2, isolated from inner bark of a Cameroonian Maytenus serrata plant, was subjected to the OSMAC (One Strain Many Compounds) approach and metabolic profiling using HPLC-HRMSn. We identified 7 prodiginines along with 26 serratamolides. Their biosynthetic pathways were elucidated by feeding with labeled precursors in combination with HRMSn. Dual culture confrontation/restriction assays of the bacterial endophyte were devised with coexisting fungal endophytes (Pestalotiopsis virgatula, Aspergillus caesiellus and Pichia spp.) as well as with unrelated, non-endophytic fungi belonging to the same genera. The assays were combined with scanning electron microscopy (SEM) as well as matrix-assisted laser desorption ionization imaging high-resolution mass spectrometry (MALDI-imaging-HRMS) for visualizing, both in high spatial and temporal resolution, the distribution and interplay of the compounds during microbial interactions. We demonstrated the effect of prodigiosin produced by endophytic S. marcescens MSRBB2 as an allelochemical that specifically inhibits coexisting endophytic fungi. Our results provide new insights into the physiological and ecological relevance of prodiginines and serratamolides within the context of allelopathy and chemical defense interaction occurring between coexisting endophytes harbored in M. serrata. PMID- 29588474 TI - Schramm-Loewner evolution and perimeter of percolation clusters of correlated random landscapes. AB - Motivated by the fact that many physical landscapes are characterized by long range height-height correlations that are quantified by the Hurst exponent H, we investigate the statistical properties of the iso-height lines of correlated surfaces in the framework of Schramm-Loewner evolution (SLE). We show numerically that in the continuum limit the external perimeter of a percolating cluster of correlated surfaces with H ? [-1, 0] is statistically equivalent to SLE curves. Our results suggest that the external perimeter also retains the Markovian properties, confirmed by the absence of time correlations in the driving function and the fact that the latter is Gaussian distributed for any specific time. We also confirm that for all H the variance of the winding angle grows logarithmically with size. PMID- 29588475 TI - NF-kB2 Genetic Variations are Significantly Associated with Non-Small Cell Lung Cancer Risk and Overall Survival. AB - During the last decade, a growing number of publications implicate NF-kB2 in NSCLC pathogenesis. Here, we investigated the clinical relevance of NF-kB2 single nucleotide polymorphisms (SNPs) rs7897947, rs11574852 and rs12769316 in NSCLC and their association with NF-kB2 protein and mRNA levels. Our data show that TT (rs7897947T >G) and AA (rs12769316G >A) genotypes were strongly associated with an increased risk for NSCLC (P = 0.019 and P = 0.003, respectively). Additionally, in multivariate analysis, TT (rs7897947T >G) homozygosity was associated with worse 2- and 3-year survival rates (P = 0.030 and P = 0.028, respectively), especially among patients with stages III/IV, who had worse 2, 3 and 5-year survival (P = 0.001, P = 0.022 and P = 0.035, respectively). In chemotherapy-treated patients, TT (rs12769316G >A) homozygosity was also associated with worse 2- and 3-year survival compared to G allele carriers (P = 0.006 and P = 0.014, respectively). Furthermore, rs12769316 was correlated with survival outcome of stage I and II patients (P = 0.031 and P = 0.006, respectively). Interestingly, amongst the patients who developed metastases, A allele carriers had better 5-year survival (P = 0.020). In addition, rs12769316 was associated with NF-kB2 protein (P = 0.001) and mRNA expression (P = 0.017) as well as with tumor maximum diameter (P = 0.025). Overall, this study suggests that rs7897947 and rs12769316 are involved in NSCLC susceptibility, in treatment response and in clinical outcome. PMID- 29588476 TI - Sequence-dependent catalytic regulation of the SpoIIIE motor activity ensures directionality of DNA translocation. AB - Transport of cellular cargo by molecular motors requires directionality to ensure proper biological functioning. During sporulation in Bacillus subtilis, directionality of chromosome transport is mediated by the interaction between the membrane-bound DNA translocase SpoIIIE and specific octameric sequences (SRS). Whether SRS regulate directionality by recruiting and orienting SpoIIIE or by simply catalyzing its translocation activity is still unclear. By using atomic force microscopy and single-round fast kinetics translocation assays we determined the localization and dynamics of diffusing and translocating SpoIIIE complexes on DNA with or without SRS. Our findings combined with mathematical modelling revealed that SpoIIIE directionality is not regulated by protein recruitment to SRS but rather by a fine-tuned balance among the rates governing SpoIIIE-DNA interactions and the probability of starting translocation modulated by SRS. Additionally, we found that SpoIIIE can start translocation from non specific DNA, providing an alternative active search mechanism for SRS located beyond the exploratory length defined by 1D diffusion. These findings are relevant in vivo in the context of chromosome transport through an open channel, where SpoIIIE can rapidly explore DNA while directionality is modulated by the probability of translocation initiation upon interaction with SRS versus non specific DNA. PMID- 29588477 TI - Machine learning approaches for large scale classification of produce. AB - The analysis and identification of different attributes of produce such as taxonomy, vendor, and organic nature is vital to verifying product authenticity in a distribution network. Though a variety of analysis techniques have been studied in the past, we present a novel data-centric approach to classifying produce attributes. We employed visible and near infrared (NIR) spectroscopy on over 75,000 samples across several fruit and vegetable varieties. This yielded 0.90-0.98 and 0.98-0.99 classification accuracies for taxonomy and farmer classes, respectively. The most significant factors in the visible spectrum were variations in the produce color due to chlorophyll and anthocyanins. In the infrared spectrum, we observed that the varying water and sugar content levels were critical to obtaining high classification accuracies. High quality spectral data along with an optimal tuning of hyperparameters in the support vector machine (SVM) was also key to achieving high classification accuracies. In addition to demonstrating exceptional accuracies on test data, we explored insights behind the classifications, and identified the highest performing approaches using cross validation. We presented data collection guidelines, experimental design parameters, and machine learning optimization parameters for the replication of studies involving large sample sizes. PMID- 29588478 TI - Ikaros family zinc finger 1 regulates dendritic cell development and function in humans. AB - Ikaros family zinc finger 1 (IKZF1) is a haematopoietic transcription factor required for mammalian B-cell development. IKZF1 deficiency also reduces plasmacytoid dendritic cell (pDC) numbers in mice, but its effects on human DC development are unknown. Here we show that heterozygous mutation of IKZF1 in human decreases pDC numbers and expands conventional DC1 (cDC1). Lenalidomide, a drug that induces proteosomal degradation of IKZF1, also decreases pDC numbers in vivo, and reduces the ratio of pDC/cDC1 differentiated from progenitor cells in vitro in a dose-dependent manner. In addition, non-classical monocytes are reduced by IKZF1 deficiency in vivo. DC and monocytes from patients with IKZF1 deficiency or lenalidomide-treated cultures secrete less IFN-alpha, TNF and IL 12. These results indicate that human DC development and function are regulated by IKZF1, providing further insights into the consequences of IKZF1 mutation on immune function and the mechanism of immunomodulation by lenalidomide. PMID- 29588479 TI - Humans significantly metabolize and excrete the mycotoxin deoxynivalenol and its modified form deoxynivalenol-3-glucoside within 24 hours. AB - For the first time, a comprehensive human intervention study was conducted to unravel the urinary excretion profile and metabolism of the fungal metabolite deoxynivalenol (DON) and its modified form deoxynivalenol-3-glucoside (DON-3 glucoside). Twenty volunteers were restricted in consuming cereals and cereal based foods for 4 days. At day 3, a single bolus of 1 ug/kg body weight of DON and a single bolus of 1 ug/kg body weight of DON-3-glucoside after a washing-out period of two months was administered, and a 24-h urine collection was performed. The urine was analysed for DON, DON-3-glucoside, 3-ADON, 15-ADON, deepoxy deoxynivalenol (DOM-1), deoxynivalenol-3-glucuronide (DON-3-glucuronide) and deoxynivalenol-15-glucuronide (DON-15-glucuronide). The urinary biomarker analysis revealed that DON and DON-3-glucoside were rapidly absorbed, distributed, metabolized and excreted. Sixty-four % of the administered DON and 58% of DON-3-glucoside was recovered in the urine collected within 24 h. DON-15 glucuronide was the most prominent urinary biomarker followed by free DON and DON 3-glucuronide. Moreover, correlations among the presence of DON-15-glucuronide and DON-3-glucuronide were observed (within 24 hours (r = 0.61)). The DOM-1 detected in the urine was higher after the DON-3-glucoside administration. The obtained results are imperative to construct a standardized method to estimate DON-intake by means of urinary biomarkers. PMID- 29588480 TI - Proteins involved in embryo-maternal interaction around the signalling of maternal recognition of pregnancy in the horse. AB - During maternal recognition of pregnancy (MRP), a conceptus-derived signal leads to the persistence of the corpus luteum and the maintenance of gestation. In the horse, the nature of this signal remains to be elucidated. Several studies have focused on the changes in gene expression during MRP, but little information exists at the protein level. The aim of this study was to identify the proteins at the embryo-maternal interface around signalling of MRP in the horse (day 13) by means of mass spectrometry. A distinct influence of pregnancy was established, with 119 proteins differentially expressed in the uterine fluid of pregnant mares compared to cyclic mares and with upregulation of several inhibitors of the prostaglandin synthesis during pregnancy. By creating an overview of the proteins at the embryo-maternal interface in the horse, this study provides a solid foundation for further targeted studies of proteins potentially involved in embryo-maternal interactions, MRP and pregnancy loss in the horse. PMID- 29588481 TI - Comparative genome-wide analysis of extracellular small RNAs from the mucormycosis pathogen Rhizopus delemar. AB - Rhizopus delemar is an emerging fungal pathogen causing devastating mucormycosis in immunocompromised individuals. The organism remains understudied and there are urgent needs for new methods of rapid disease diagnosis for timely therapy. Extracellular vesicles with encapsulated RNAs have recently been discovered to have great potential applications for disease diagnoses and treatments. To explore the utilization of ex-RNA in studies of mucormycosis, we have performed RNA-Seq of ex-sRNAs from two clinical strains of R. delemar. Approximately 3.3 and 3.2 million clean reads were obtained from FGSC-9543 and CDC-8219 strains, respectively. The median sequence length of the sRNAs was 22 nts, with a minimum of 18 and a maximum of 30 nts. Further annotation identified 560 and 526 miRNAs from FGSC-9543 and CDC-8219 strains, respectively. miRNA target prediction and analysis of GO and KEGG pathways have revealed that the regulation of metabolism, secondary metabolite biosynthesis, and two-component system signaling are important during growth. We have also validated RNA-Seq by qRT-PCR and Northern blotting analysis of randomly selected miRNAs. Our results show that R. delemar has a rich reservoir of secreted ex-sRNAs and our studies could facilitate the development of improved diagnostic methods as well as elucidating virulence mechanisms for R. delemar infection. PMID- 29588482 TI - Synthesis of NiMn-LDH Nanosheet@Ni3S2 Nanorod Hybrid Structures for Supercapacitor Electrode Materials with Ultrahigh Specific Capacitance. AB - One of the key challenges for pseudocapacitive electrode materials with highly effective capacitance output and future practical applications is how to rationally construct hierarchical and ordered hybrid nanoarchitecture through the simple process. Herein, we design and synthesize a novel NiMn-layered double hydroxide nanosheet@Ni3S2 nanorod hybrid array supported on porous nickel foam via a one-pot hydrothermal method. Benefited from the ultrathin and rough nature, the well-defined porous structure of the hybrid array, as well as the synergetic effect between NiMn-layered double hydroxide nanosheets and Ni3S2 nanorods, the as-fabricated hybrid array-based electrode exhibits an ultrahigh specific capacitance of 2703 F g-1 at 3 A g-1. Moreover, the asymmetric supercapacitor with this hybrid array as a positive electrode and wood-derived activated carbon as a negative electrode demonstrates high energy density (57 Wh Kg-1 at 738 W Kg 1) and very good electrochemical cycling stability. PMID- 29588483 TI - Genome plasticity is governed by double strand break DNA repair in Streptomyces. AB - The linear chromosome of the bacterium Streptomyces exhibits a remarkable genetic organization with grossly a central conserved region flanked by variable chromosomal arms. The terminal diversity co-locates with an intense DNA plasticity including the occurrence of large deletions associated to circularization and chromosomal arm exchange. These observations prompted us to assess the role of double strand break (DSB) repair in chromosome plasticity following. For that purpose, DSBs were induced along the chromosome using the meganuclease I-SceI. DSB repair in the central region of the chromosome was mutagenic at the healing site but kept intact the whole genome structure. In contrast, DSB repair in the chromosomal arms was mostly associated to the loss of the targeted chromosomal arm and extensive deletions beyond the cleavage sites. While homologous recombination occurring between copies of DNA sequences accounted for the most part of the chromosome rescue events, Non Homologous End Joining was involved in mutagenic repair as well as in huge genome rearrangements (i.e. circularization). Further, NHEJ repair was concomitant with the integration of genetic material at the healing site. We postulate that DSB repair drives genome plasticity and evolution in Streptomyces and that NHEJ may foster horizontal transfer in the environment. PMID- 29588484 TI - Neurosurgical untethering with or without syrinx drainage results in high patient satisfaction and favorable clinical outcome in post-traumatic myelopathy patients. AB - STUDY DESIGN: Retrospective data collection and patient-reported outcome measures. OBJECTIVES: To investigate surgical outcome, complications, and patient satisfaction in patients with chronic SCI and symptomatic post-traumatic progressive myelopathy (PPM) who underwent neurosurgical untethering and/or spinal cord cyst drainage with the aim of preventing further neurological deterioration. SETTING: Single-center study at an academic neurosurgery department. METHODS: All SCI patients who underwent neurosurgery between 1996 and 2013 were retrospectively included. All medical charts and the treating surgeon's operative reports were reviewed to identify surgical indications, surgical technique, and post-operative complications. A questionnaire and an EQ-5D instrument were used to assess patient's self-described health status and satisfaction at long-term follow-up. RESULTS: Fifty-two patients (43 men, 9 women) were identified, of whom five were dead and one was lost to follow-up. Main indications for surgery were pain (54%), motor (37%), or sensory (8%) impairment, and spasticity (2.0%). Overall complications were rare (8%). At follow-up, the subjectively perceived outcome was improved in 24 and remained unchanged in 21 patients. Thus, the surgical aim was met in 87% of patients. Of the 46 eligible patients, 38 responded to the questionnaire of whom 65% were satisfied with the surgical results. Patients with cervical lesions were more satisfied with the surgical treatment than patients with thoracic/thoracolumbar lesions (p = 0.05). CONCLUSIONS: Neurosurgical untethering and/or cyst drainage in chronic SCI patients and PPM resulted in a high degree of patient satisfaction, particularly in cervical SCI patients with minimal complications. PMID- 29588485 TI - Association between serum uric acid and cardiovascular risk in nonhypertensive and nondiabetic individuals: The Taiwan I-Lan Longitudinal Aging Study. AB - Serum uric acid level is a risk factor for cardiovascular disease (CVD). However, whether it is an independent risk factor or not remains controversial. We analyzed the association between serum uric acid level and cardiovascular risk. In total, 973 nonhypertensive and nondiabetic participants in the I-Lan Longitudinal Aging Study were eligible for this study. Subjects were divided into tertiles according to uric acid levels. The 10-year cardiovascular risk was calculated using Framingham risk score (FRS). Study subjects in the highest tertile of serum uric acid level were older, more likely to be male, and had higher systolic blood pressure, body mass index, carotid artery intima-media thickness and serum triglyceride, high-sensitivity C-reactive protein, and low density lipoprotein cholesterol levels and lower serum high-density lipoprotein cholesterol levels (all p < 0.05). Subjects in the highest tertile had significantly higher FRS (p < 0.001). After adjusting for other risk factors, serum uric acid level remained associated significantly with the FRS (p < 0.05). In binary logistic regression analysis, the serum uric acid level was an independent predictive factor for high (>=20%) FRS (odds ratio 1.33, 95% confidence interval 1.10-1.68). These findings warrant attention to this cardiovascular risk factor in apparently healthy adults. PMID- 29588486 TI - Structural prediction of host-guest structure in lithium at high pressure. AB - Ab initio random structure searching (AIRSS) technique is used to identify the high-pressure phases of lithium (Li). We proposed the transition mechanism from the fcc to host-guest (HG) structures at finite temperature and high pressure. This complex structural phase transformation has been calculated using ab initio lattice dynamics with finite displacement method which confirms the dynamical harmonic stabilization of the HG structure. The electron distribution between the host-host atoms has also been investigated by electron localization function (ELF). The strongly localized electron of p bond has led to the stability of the HG structure. This remarkable result put the HG structure to be a common high pressure structure among alkali metals. PMID- 29588487 TI - Trophoblast-derived CXCL16 induces M2 macrophage polarization that in turn inactivates NK cells at the maternal-fetal interface. AB - Decidual macrophages (dMPhi) are distinct from the conventional macrophages present in other tissues and express M2 macrophage markers, but the molecular mechanisms of formation and the roles of M2 MPhi during pregnancy have not been completely elucidated. The crosstalk between decidual natural killer cells (dNK) and dMPhi plays an important role in the maintenance of maternal-fetal immune tolerance. Here, CXCL16 derived from first-trimester trophoblast cells induces the polarization of human M2 macrophages. The M2 MPhi polarized by CXCL16 exhibit decreased interleukin-15 production, which facilitates the inactivation of NK cells. The cytotoxicity of NK cells is attenuated by the CXCL16-polarized M2 MPhi. The data shown in the present study provide evidence to support the hypothesis that CXCL16 secreted by trophoblast cells is a key molecule involved in decidual M2 MPhi polarization, which in turn regulates the killing ability of NK cells, thereby contributing to the homeostatic and immune-tolerant milieu required for successful fetal development. PMID- 29588488 TI - Dynamic analysis of the interactions between Si/SiO2 quantum dots and biomolecules for improving applications based on nano-bio interfaces. AB - Due to their outstanding properties, quantum dots (QDs) received a growing interest in the biomedical field, but it is of major importance to investigate and to understand their interaction with the biomolecules. We examined the stability of silicon QDs and the time evolution of QDs - protein corona formation in various biological media (bovine serum albumin, cell culture medium without or supplemented with 10% fetal bovine serum-FBS). Changes in the secondary structure of BSA were also investigated over time. Hydrodynamic size and zeta potential measurements showed an evolution in time indicating the nanoparticle-protein interaction. The protein corona formation was also dependent on time, albumin adsorption reaching the peak level after 1 hour. The silicon QDs adsorbed an important amount of FBS proteins from the first 5 minutes of incubation that was maintained for the next 8 hours, and diminished afterwards. Under protein-free conditions the QDs induced cell membrane damage in a time-dependent manner, however the presence of serum proteins attenuated their hemolytic activity and maintained the integrity of phosphatidylcholine layer. This study provides useful insights regarding the dynamics of BSA adsorption and interaction of silicon QDs with proteins and lipids, in order to understand the role of QDs biocorona. PMID- 29588489 TI - Diagnostic accuracy of liver stiffness measurement in chronic hepatitis B patients with normal or mildly elevated alanine transaminase levels. AB - We aimed to evaluate the diagnostic accuracy of liver stiffness measurement (LSM) in 188 chronic hepatitis B (CHB) patients with alanine transaminase (ALT) <= twice the upper limit of normal (ULN). Liver fibrosis was staged using METAVIR scoring system. Define significant fibrosis as F2-F4, severe fibrosis as F3-F4, and cirrhosis as F4. To predict F2-F4, the AUROC of LSM was higher than that of APRI (0.86 vs 0.73, p = 0.001) and FIB-4 (0.86 vs 0.61, p < 0.001). To predict F4, the AUROC of LSM was also higher than that of APRI (0.93 vs 0.77, p = 0.012) and FIB-4 (0.93 vs 0.64, p < 0.001). Patients with ALT levels 1-2 ULN had higher cut-off values than patients with normal ALT levels for the diagnosis of F2-F4 (6.5 vs 6 kPa) and F4 (10.2 vs 7.8 kPa). Using cut-off values regardless of ALT levels, the diagnostic accuracy of LSM was 81% for F2-F4, and 89% for F4. Applying ALT-stratified cut-off values, the diagnostic accuracy of LSM was 82% for F2-F4, and 86% for F4. In conclusion, LSM is a reliable noninvasive test for the diagnosis of liver fibrosis. Applying ALT-stratified cut-off values did not enhance diagnostic accuracy of LSM in CHB patients with ALT <= 2 ULN. PMID- 29588490 TI - LentiPro26: novel stable cell lines for constitutive lentiviral vector production. AB - Lentiviral vectors (LVs) are excellent tools to promote gene transfer and stable gene expression. Their potential has been already demonstrated in gene therapy clinical trials for the treatment of diverse disorders. For large scale LV production, a stable producer system is desirable since it allows scalable and cost-effective viral productions, with increased reproducibility and safety. However, the development of stable systems has been challenging and time consuming, being the selection of cells presenting high expression levels of Gag Pro-Pol polyprotein and the cytotoxicity associated with some viral components, the main limitations. Hereby is described the establishment of a new LV producer cell line using a mutated less active viral protease to overcome potential cytotoxic limitations. The stable transfection of bicistronic expression cassettes with re-initiation of the translation mechanism enabled the generation of LentiPro26 packaging populations supporting high titers. Additionally, by skipping intermediate clone screening steps and performing only one final clone screening, it was possible to save time and generate LentiPro26-A59 cell line, that constitutively produces titers above 106 TU.mL-1.day-1, in less than six months. This work constitutes a step forward towards the development of improved LV producer cell lines, aiming to efficiently supply the clinical expanding gene therapy applications. PMID- 29588491 TI - Identification of inhibitors regulating cell proliferation and FUS-DDIT3 expression in myxoid liposarcoma using combined DNA, mRNA, and protein analyses. AB - FUS-DDIT3 belongs to the FET (FUS, EWSR1, and TAF15) family of fusion oncogenes, which collectively are considered to be key players in tumor development. Even though over 90% of all myxoid liposarcomas (MLS) have a FUS-DDIT3 gene fusion, there is limited understanding of the signaling pathways that regulate its expression. In order to study cell proliferation and FUS-DDIT3 regulation at mRNA and protein levels, we first developed a direct cell lysis approach that allows DNA, mRNA, and protein to be analyzed in the same sample using quantitative PCR, reverse transcription quantitative qPCR and proximity ligation assay, respectively. We screened 70 well-characterized kinase inhibitors and determined their effects on cell proliferation and expression of FUS-DDIT3 and FUS at both mRNA and protein levels in the MLS 402-91 cell line, where twelve selected inhibitors were evaluated further in two additional MLS cell lines. Both FUS DDIT3 and FUS mRNA expression correlated with cell proliferation and both transcripts were co-regulated in most conditions, indicating that the common 5' FUS promotor is important in transcriptional regulation. In contrast, FUS-DDIT3 and FUS protein levels displayed more cell line dependent expression. Furthermore, most JAK inhibitors caused FUS-DDIT3 downregulation at both mRNA and protein levels. In conclusion, defining factors that regulate FUS-DDIT3 expression opens new means to understand MLS development at the molecular level. PMID- 29588493 TI - Bilateral geochemical asymmetry in the Karoo large igneous province. AB - In the Karoo large igneous province, the geochemical assessment of mantle source variability and structure is hampered by probable crustal contamination overprinting of compositionally diverse flood basalts. Mantle source characteristics have been defined only for exceptional, primitive rock types. Here I use a compiled dataset for over 800 samples to demonstrate that the abundance of Nb relative to Zr, Ti, and Y provides a useful geochemical tracer of mantle sources for variably contaminated rock types of the Karoo province. Variations in the relative abundance of Nb reveal emplacement of distinctive, Nb undepleted and Nb-depleted magmas in the North Karoo and South Karoo sub provinces, respectively, and clarify correlation between flood basalts and previously proposed mantle source components. Judging from plate tectonic reconstructions and the compositions of plausible mantle source components, the geochemical bilateral asymmetry in Karoo may reflect tapping of contrasting plume and upper mantle reservoirs in the two sub-provinces. PMID- 29588492 TI - SFTS phlebovirus promotes LC3-II accumulation and nonstructural protein of SFTS phlebovirus co-localizes with autophagy proteins. AB - Autophagy is essential for eukaryotic cell homeostasis and can perform both anti viral and pro-viral roles depending on the kinds of viruses, cell types and cell environment. Severe fever with thrombocytopenia syndrome phlebovirus (SFTSV) is a newly discovered tick-borne virus in the Phenuiviridae family that causes a severe hemorrhagic fever disease in East Asia. In this study we determined interactions between SFTSV and autophagy. Our results showed that LC3-II (microtubule associated protein 1 light chain 3-II) protein accumulated from 4 h to 24 h after SFTSV infection compared to mock-infected Vero cells, and the use of E64d and pepstatin A did not affect the expression of LC3-II protein, which indicated that the increased LC3-II may be the result of inhibition of autophagic degradation caused by SFTSV infection. However, knockdown of LC3B promotes SFTSV replication, which indicated a negative role of LC3B protein in SFTSV replication. We also detected co-localization of SFTSV non-structure (NSs) protein with LC3B, p62 and Lamp2b respectively in SFTSV infected Vero cells, which indicated the possibility of selective autophagy or chaperone-mediated autophagy involving in SFTSV infection. Our results indicated that SFTSV infection promotes LC3 accumulation and several proteins of the autophagy pathway co-localize with NSs protein during SFTSV infection. PMID- 29588494 TI - Global negative effects of nitrogen deposition on soil microbes. AB - Soil microbes comprise a large portion of the genetic diversity on Earth and influence a large number of important ecosystem processes. Increasing atmospheric nitrogen (N) deposition represents a major global change driver; however, it is still debated whether the impacts of N deposition on soil microbial biomass and respiration are ecosystem-type dependent. Moreover, the extent of N deposition impacts on microbial composition remains unclear. Here we conduct a global meta analysis using 1408 paired observations from 151 studies to evaluate the responses of soil microbial biomass, composition, and function to N addition. We show that nitrogen addition reduced total microbial biomass, bacterial biomass, fungal biomass, biomass carbon, and microbial respiration. Importantly, these negative effects increased with N application rate and experimental duration. Nitrogen addition reduced the fungi to bacteria ratio and the relative abundances of arbuscular mycorrhizal fungi and gram-negative bacteria and increased gram positive bacteria. Our structural equation modeling showed that the negative effects of N application on soil microbial abundance and composition led to reduced microbial respiration. The effects of N addition were consistent across global terrestrial ecosystems. Our results suggest that atmospheric N deposition negatively affects soil microbial growth, composition, and function across all terrestrial ecosystems, with more pronounced effects with increasing N deposition rate and duration. PMID- 29588495 TI - Drinking water microbiome assembly induced by water stagnation. AB - What happens to tap water when you are away from home? Day-to-day water stagnation in building plumbing can potentially result in water quality deterioration (e.g., lead release or pathogen proliferation), which is a major public health concern. However, little is known about the microbial ecosystem processes in plumbing systems, hindering the development of biological monitoring strategies. Here, we track tap water microbiome assembly in situ, showing that bacterial community composition changes rapidly from the city supply following ~6 day stagnation, along with an increase in cell count from 103 cells/mL to upwards of 7.8 * 105 cells/mL. Remarkably, bacterial community assembly was highly reproducible in this built environment system (median Spearman correlation between temporal replicates = 0.78). Using an island biogeography model, we show that neutral processes arising from the microbial communities in the city water supply (i.e., migration and demographic stochasticity) explained the island community composition in proximal pipes (Goodness-of-fit = 0.48), yet declined as water approached the faucet (Goodness-of-fit = 0.21). We developed a size-effect model to simulate this process, which indicated that pipe diameter drove these changes by mediating the kinetics of hypochlorite decay and cell detachment, affecting selection, migration, and demographic stochasticity. Our study challenges current water quality monitoring practice worldwide which ignore biological growth in plumbing, and suggests the island biogeography model as a useful framework to evaluate building water system quality.

AB - We performed RNA sequencing, identified components of the immune system and mapped early immune responses of lumpfish (Cyclopterus lumpus) leukocytes following in vitro exposure to the pathogenic bacterium Vibrio anguillarum O1. This is the first characterization of immune molecules in lumpfish at the gene level. In silico analyses revealed that genes encoding proteins involved in pathogen recognition, cell signaling and cytokines in mammals and teleosts are conserved in lumpfish. Unique molecules were also identified. Pathogen recognition components include 13 TLRs, several NLRs and complement factors. Transcriptome-wide analyses of immune responses 6 and 24 hours post bacterial exposure revealed differential expression of 9033 and 15225 genes, respectively. These included TLR5S, IL-1beta, IL-8, IL-6, TNFalpha, IL-17A/F3, IL-17C and several components of the complement system. The data generated will be valuable for comparative studies and make an important basis for further functional analyses of immune and pathogenicity mechanisms. Such knowledge is also important for design of immunoprophylactic measures in lumpfish, a species of fish now farmed intensively for use as cleaner-fish in Atlantic salmon (Salmo salar) aquaculture.

PMID- 29588498 TI - Topological estimation of signal flow in complex signaling networks. AB - In a cell, any information about extra- or intra-cellular changes is transferred and processed through a signaling network and dysregulation of signal flow often leads to disease such as cancer. So, understanding of signal flow in the signaling network is critical to identify drug targets. Owing to the development of high-throughput measurement technologies, the structure of a signaling network is becoming more available, but detailed kinetic parameter information about molecular interactions is still very limited. A question then arises as to whether we can estimate the signal flow based only on the structure information of a signaling network. To answer this question, we develop a novel algorithm that can estimate the signal flow using only the topological information and apply it to predict the direction of activity change in various signaling networks. Interestingly, we find that the average accuracy of the estimation algorithm is about 60-80% even though we only use the topological information. We also find that this predictive power gets collapsed if we randomly alter the network topology, showing the importance of network topology. Our study provides a basis for utilizing the topological information of signaling networks in precision medicine or drug target discovery. PMID- 29588497 TI - Targeted in vivo knock-in of human alpha-1-antitrypsin cDNA using adenoviral delivery of CRISPR/Cas9. AB - Serum deficiency diseases such as alpha-1-antitrypsin deficiency are characterized by reduced function of serum proteins, caused by deleterious genetic mutations. These diseases are promising targets for genetic interventions. Gene therapies using viral vectors have been used to introduce correct copies of the disease-causing gene in preclinical and clinical studies. However, these studies highlighted that disease-alleviating gene expression is lost over time. Integration into a specific chromosomal site could provide lasting therapeutic expression to overcome this major limitation. Additionally, targeted integration could avoid detrimental mutagenesis associated with integrative vectors, such as tumorigenesis or functional gene perturbation. To test if adenoviral vectors can facilitate long-term gene expression through targeted integration, we somatically incorporated the human alpha-1-antitrypsin gene into the ROSA26 "safe harbor" locus in murine livers, using CRISPR/Cas9. We found adenoviral-mediated delivery of CRISPR/Cas9 achieved gene editing outcomes persisting over 200 days. Furthermore, gene knock-in maintained greater levels of the serum protein than provided by episomal expression. Importantly, our "knock in" approach is generalizable to other serum proteins and supports in vivo cDNA replacement therapy to achieve stable gene expression. PMID- 29588500 TI - Socioeconomic and health system factors associated with lower utilization of hematopoietic cell transplantation in older patients with acute myeloid leukemia. AB - Receipt of hematopoietic cell transplantation (HCT) can improve overall survival in older patients with intermediate or high-risk acute myeloid leukemia (AML); however, utilization of HCT is poor. It is important to understand the factors that affect the receipt of HCT in a real-world setting among the older patients. We utilized the National Cancer Database to determine receipt of HCT in older patients (61-75 years) with intermediate or high-risk AML reported between 2003 and 2012. Multivariate logistic regression analysis was used to determine factors associated with receipt of HCT. Only 5.5% of older patients (n = 17,555) underwent HCT. Factors associated with a lower likelihood of receiving HCT included receipt of care in a non-academic hospital, race other than white, older age, Charlson comorbidity score of >=1, uninsured status, Medicaid or Medicare insurance, and lower educational status. The receipt of HCT in older patients is low and varies based on biological as well as non-biologic factors, such as hospital type, insurance, and educational status. Nationwide efforts to improve access to HCT for appropriate patients are necessary. PMID- 29588501 TI - Lumenal exposed regions of the D1 protein of PSII are long enough to be degraded by the chloroplast Deg1 protease. AB - Degradation of the D1 protein of photosystem II (PSII) reaction center is a pre requisite for the repair cycle from photoinhibition. Two types of thylakoid proteases, FtsH and Deg, have been demonstrated to participate in this process. However, the location of the proteolytic sites of the lumenal Deg1 protease within its internal sphere raised the question whether the lumenal-exposed regions of D1 are indeed long enough to reach these sites. Implanting these regions into the stable GFP rendered it sensitive to the presence of Deg1 in vitro, demonstrating that the flexible regions of D1 that protrude into the lumen can penetrate through the three side-openings of Deg1 and reach its internal proteolytic sites. This mode of action, facilitating cooperation between proteases on both sides of the thylakoid membranes, should be applicable to the degradation of other integral thylakoid membrane proteins as well. PMID- 29588503 TI - Cohesively enhanced electrical conductivity and thermal stability of silver nanowire networks by nickel ion bridge joining. AB - A facile method for producing high-performance nickel enhanced silver nanowire (Ag NW) transparent electrodes on a flexible substrate is reported. The modified electroplating method called enhanced nickel ion bridge joining of Ag NWs, which provides a new route for improving the loose junctions in bare Ag NW networks. The sheet resistance of Ag NW electrode drops from over 2000 Omega sq-1 to 9.4 Omega sq-1 with excellent thermal uniformity after the electroplating process within 10 s. Nickel enhanced Ag NW transparent films are applied on flexible heaters with good thermal stability (165 degrees C for 2 h) and mechanical flexibility (3500 cycles under 2.5 mm bending radius) after mechanical bending process. Moreover, the mechanism of nickel growth is also confirmed that the nickel electroplating of the Ag NWs obeyed Faraday's Laws. PMID- 29588502 TI - Extensive molecular tinkering in the evolution of the membrane attachment mode of the Rheb GTPase. AB - Rheb is a conserved and widespread Ras-like GTPase involved in cell growth regulation mediated by the (m)TORC1 kinase complex and implicated in tumourigenesis in humans. Rheb function depends on its association with membranes via prenylated C-terminus, a mechanism shared with many other eukaryotic GTPases. Strikingly, our analysis of a phylogenetically rich sample of Rheb sequences revealed that in multiple lineages this canonical and ancestral membrane attachment mode has been variously altered. The modifications include: (1) accretion to the N-terminus of two different phosphatidylinositol 3-phosphate binding domains, PX in Cryptista (the fusion being the first proposed synapomorphy of this clade), and FYVE in Euglenozoa and the related undescribed flagellate SRT308; (2) acquisition of lipidic modifications of the N-terminal region, namely myristoylation and/or S-palmitoylation in seven different protist lineages; (3) acquisition of S-palmitoylation in the hypervariable C-terminal region of Rheb in apusomonads, convergently to some other Ras family proteins; (4) replacement of the C-terminal prenylation motif with four transmembrane segments in a novel Rheb paralog in the SAR clade; (5) loss of an evident C terminal membrane attachment mechanism in Tremellomycetes and some Rheb paralogs of Euglenozoa. Rheb evolution is thus surprisingly dynamic and presents a spectacular example of molecular tinkering. PMID- 29588504 TI - Saturation-Recovery Myocardial T1-Mapping during Systole: Accurate and Robust Quantification in the Presence of Arrhythmia. AB - Myocardial T1-mapping, a cardiac magnetic resonance imaging technique, facilitates a quantitative measure of fibrosis which is linked to numerous cardiovascular symptoms. To overcome the problems of common techniques, including lack of accuracy and robustness against partial-voluming and heart-rate variability, we introduce a systolic saturation-recovery T1-mapping method. The Saturation-Pulse Prepared Heart-rate independent Inversion-Recovery (SAPPHIRE) T1 mapping method was modified to enable imaging during systole. Phantom measurements were used to evaluate the insensitivity of systolic T1-mapping towards heart-rate variability. In-vivo feasibility and accuracy were demonstrated in ten healthy volunteers with native and post-contrast T1-mappping during systole and diastole. To show benefits in the presence of RR-variability, six arrhythmic patients underwent native T1-mapping. Resulting systolic SAPPHIRE T1-values showed no dependence on arrhythmia in phantom (CoV < 1%). In-vivo, significantly lower T1 (1563 +/- 56 ms, precision: 84.8 ms) and ECV-values (0.20 +/- 0.03) than during diastole (T1 = 1580 +/- 62 ms, p = 0.0124; precision: 60.2 ms, p = 0.03; ECV = 0.21 +/- 0.03, p = 0.0098) were measured, with a strong correlation of systolic and diastolic T1 (r = 0.89). In patients, mis-triggering induced motion caused significant imaging artifacts in diastolic T1-maps, whereas systolic T1-maps displayed resilience to arrythmia. In conclusion, the proposed method enables saturation-recovery T1-mapping during systole, providing increased robustness against partial-voluming compared to diastolic imaging, for the benefit of T1-measurements in arrhythmic patients. PMID- 29588505 TI - Predation scars may influence host susceptibility to pathogens: evaluating the role of corallivores as vectors of coral disease. AB - Infectious diseases not regulated by host density, such as vector-borne diseases, have the potential to drive population declines and extinctions. Here we test the vector potential of the snail Drupella sp. and butterflyfish Chaetodon plebeius for two coral diseases, black band (BBD) and brown band (BrB) disease. Drupella transmitted BrB to healthy corals in 40% of cases immediately following feeding on infected corals, and even in 12% of cases 12 and 24 hours following feeding. However, Drupella was unable to transmit BBD in either transmission treatment. In a field experiment testing the vector potential of naturally-occurring fish assemblages, equivalent numbers of caged and uncaged coral fragments became infected with either BrB, BBD or skeletal eroding band, indicating that corallivorous fish were unlikely to have caused transmission. In aquaria, C. plebeius did not transmit either BBD or BrB, even following extended feeding on both infected and healthy nubbins. A literature review confirmed only four known coral disease vectors, all invertebrates, corroborating our conclusion that polyp feeding fishes are unlikely to be vectors of coral diseases. This potentially because polyp-feeding fishes produce shallow lesions, not allowing pathogens to invade coral tissues. In contrast, corallivorous invertebrates that create deeper feeding scars increase pathogens transmission. PMID- 29588507 TI - Human-mediated dispersal of cats in the Neolithic Central Europe. AB - Archeological and genetic evidence suggest that all domestic cats derived from the Near Eastern wildcat (Felis silvestris lybica) and were first domesticated in the Near East around 10,000 years ago. The spread of the domesticated form in Europe occurred much later, primarily mediated by Greek and Phoenician traders and afterward by Romans who introduced cats to Western and Central Europe around 2000 years ago. We investigated mtDNA of Holocene Felis remains and provide evidence of an unexpectedly early presence of cats bearing the Near Eastern wildcat mtDNA haplotypes in Central Europe, being ahead of Roman period by over 2000 years. The appearance of the Near Eastern wildcats in Central Europe coincides with the peak of Neolithic settlement density, moreover most of those cats belonged to the same mtDNA lineages as those domesticated in the Near East. Thus, although we cannot fully exclude that the Near Eastern wildcats appeared in Central Europe as a result of introgression with European wildcat, our findings support the hypothesis that the Near Eastern wildcats spread across Europe together with the first farmers, perhaps as commensal animals. We also found that cats dated to the Neolithic period belonged to different mtDNA lineages than those brought to Central Europe in Roman times, this supports the hypothesis that the gene pool of contemporary European domestic cats might have been established from two different source populations that contributed in different periods. PMID- 29588506 TI - Narrow-sense heritability estimation of complex traits using identity-by-descent information. AB - Heritability is a fundamental parameter in genetics. Traditional estimates based on family or twin studies can be biased due to shared environmental or non additive genetic variance. Alternatively, those based on genotyped or imputed variants typically underestimate narrow-sense heritability contributed by rare or otherwise poorly tagged causal variants. Identical-by-descent (IBD) segments of the genome share all variants between pairs of chromosomes except new mutations that have arisen since the last common ancestor. Therefore, relating phenotypic similarity to degree of IBD sharing among classically unrelated individuals is an appealing approach to estimating the near full additive genetic variance while possibly avoiding biases that can occur when modeling close relatives. We applied an IBD-based approach (GREML-IBD) to estimate heritability in unrelated individuals using phenotypic simulation with thousands of whole-genome sequences across a range of stratification, polygenicity levels, and the minor allele frequencies of causal variants (CVs). In simulations, the IBD-based approach produced unbiased heritability estimates, even when CVs were extremely rare, although precision was low. However, population stratification and non-genetic familial environmental effects shared across generations led to strong biases in IBD-based heritability. We used data on two traits in ~120,000 people from the UK Biobank to demonstrate that, depending on the trait and possible confounding environmental effects, GREML-IBD can be applied to very large genetic datasets to infer the contribution of very rare variants lost using other methods. However, we observed apparent biases in these real data, suggesting that more work may be required to understand and mitigate factors that influence IBD-based heritability estimates. PMID- 29588508 TI - The effects of recent changes in breeding preferences on maintaining traditional Dutch chicken genomic diversity. AB - Traditional Dutch chicken breeds are marginalised breeds of ornamental and cultural-historical importance. In the last decades, miniaturising of existing breeds (so called neo-bantam) has become popular and resulted in alternatives to original large breeds. However, while backcrossing is increasing the neo-bantams homozygosity, genetic exchange between breeders may increase their genetic diversity. We use the 60 K SNP array to characterise the genetic diversity, demographic history, and level of inbreeding of Dutch heritage breeds, and particularly of neo-bantams. Commercial white layers are used to contrast the impact of management strategy on genetic diversity and demography. A high proportion of alleles was found to be shared between large fowls and neo-bantams, suggesting gene flow during neo-bantams development. Population admixture analysis supports these findings, in addition to revealing introgression from neo bantams of the same breed and of phenotypically similar breeds. The prevalence of long runs of homozygosity (ROH) confirms the importance of recent inbreeding. A high diversity in management, carried out in small breeding units explains the high heterogeneity in diversity and ROH profile displayed by traditional breeds compared to commercial lines. Population bottlenecks may explain the long ROHs in large fowls, while repetitive backcrossing for phenotype selection may account for them in neo-bantams. Our results highlight the importance of using markers to inform breeding programmes on potentially harmful homozygosity to prevent loss of genetic diversity. We conclude that bantamisation has generated unique and identifiable genetic diversity. However, this diversity can only be preserved in the near future through structured breeding programmes. PMID- 29588509 TI - The road to evolutionary success: insights from the demographic history of an Amazonian palm. AB - Evolutionary success, as demonstrated by high abundance and a wide geographical range, is related to genetic variation and historical demography. Here we assess how climatic change during the Quaternary influenced the demography and distribution of the Neotropical swamp palm Mauritia flexuosa. Using microsatellite loci and coalescent analyses we examined how demographical dynamics affected genetic diversity, effective population size and connectivity through time and space. Mauritia flexuosa presents significant genetic differentiation between the Amazonian and Cerrado biomes and among different river basins. Amazonian lineages are ancient compared to lineages from the Cerrado, a pattern corroborated using the fossil pollen record, where the species was absent from the Cerrado during the cold and dry periods of the last glacial cycles, then returned during the wet, interglacial phases. Coalescent simulations show that the pattern of observed genetic diversity for M. flexuosa is most likely due to a range retraction during the Last Glacial Maximum, leading to multiple refugia and resulting in high differentiation between Amazonian and Cerrado biomes. Isolation-by-distance and by-environment also shaped the distribution and evolutionary success of M. flexuosa. Our study provides new insights into the historical factors that affected geographical distribution and structure genetic diversity, contributing to long-term evolutionary success. PMID- 29588510 TI - Modelling the co-evolution of indirect genetic effects and inherited variability. AB - When individuals interact, their phenotypes may be affected not only by their own genes but also by genes in their social partners. This phenomenon is known as Indirect Genetic Effects (IGEs). In aquaculture species and some plants, however, competition not only affects trait levels of individuals, but also inflates variability of trait values among individuals. In the field of quantitative genetics, the variability of trait values has been studied as a quantitative trait in itself, and is often referred to as inherited variability. Such studies, however, consider only the genetic effect of the focal individual on trait variability and do not make a connection to competition. Although the observed phenotypic relationship between competition and variability suggests an underlying genetic relationship, the current quantitative genetic models of IGE and inherited variability do not allow for such a relationship. The lack of quantitative genetic models that connect IGEs to inherited variability limits our understanding of the potential of variability to respond to selection, both in nature and agriculture. Models of trait levels, for example, show that IGEs may considerably change heritable variation in trait values. Currently, we lack the tools to investigate whether this result extends to variability of trait values. Here we present a model that integrates IGEs and inherited variability. In this model, the target phenotype, say growth rate, is a function of the genetic and environmental effects of the focal individual and of the difference in trait value between the social partner and the focal individual, multiplied by a regression coefficient. The regression coefficient is a genetic trait, which is a measure of cooperation; a negative value indicates competition, a positive value cooperation, and an increasing value due to selection indicates the evolution of cooperation. In contrast to the existing quantitative genetic models, our model allows for co-evolution of IGEs and variability, as the regression coefficient can respond to selection. Our simulations show that the model results in increased variability of body weight with increasing competition. When competition decreases, i.e., cooperation evolves, variability becomes significantly smaller. Hence, our model facilitates quantitative genetic studies on the relationship between IGEs and inherited variability. Moreover, our findings suggest that we may have been overlooking an entire level of genetic variation in variability, the one due to IGEs. PMID- 29588511 TI - Structure and Distribution of an Unrecognized Interstitium in Human Tissues. AB - Confocal laser endomicroscopy (pCLE) provides real-time histologic imaging of human tissues at a depth of 60-70 MUm during endoscopy. pCLE of the extrahepatic bile duct after fluorescein injection demonstrated a reticular pattern within fluorescein-filled sinuses that had no known anatomical correlate. Freezing biopsy tissue before fixation preserved the anatomy of this structure, demonstrating that it is part of the submucosa and a previously unappreciated fluid-filled interstitial space, draining to lymph nodes and supported by a complex network of thick collagen bundles. These bundles are intermittently lined on one side by fibroblast-like cells that stain with endothelial markers and vimentin, although there is a highly unusual and extensive unlined interface between the matrix proteins of the bundles and the surrounding fluid. We observed similar structures in numerous tissues that are subject to intermittent or rhythmic compression, including the submucosae of the entire gastrointestinal tract and urinary bladder, the dermis, the peri-bronchial and peri-arterial soft tissues, and fascia. These anatomic structures may be important in cancer metastasis, edema, fibrosis, and mechanical functioning of many or all tissues and organs. In sum, we describe the anatomy and histology of a previously unrecognized, though widespread, macroscopic, fluid-filled space within and between tissues, a novel expansion and specification of the concept of the human interstitium. PMID- 29588512 TI - Multivariable clinical-genetic risk model for predicting venous thromboembolic events in patients with cancer. AB - BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death among patients with cancer. Outpatients with cancer should be periodically assessed for VTE risk, for which the Khorana score is commonly recommended. However, it has been questioned whether this tool is sufficiently accurate at identifying patients who should receive thromboprophylaxis. The present work proposes a new index, TiC-Onco risk score to be calculated at the time of diagnosis of cancer, that examines patients' clinical and genetic risk factors for thrombosis. METHODS: We included 391 outpatients with a recent diagnosis of cancer and candidates for systemic outpatient chemotherapy. All were treated according to standard guidelines. The study population was monitored for 6 months, and VTEs were recorded. The Khorana and the TiC-Onco scores were calculated for each patient and their VTE predictive accuracy VTEs was compared. RESULTS: We recorded 71 VTEs. The TiC-Onco risk score was significantly better at predicting VTE than the Khorana score (AUC 0.73 vs. 0.58, sensitivity 49 vs. 22%, specificity 81 vs. 82%, PPV 37 vs. 22%, and NPV 88 vs. 82%). CONCLUSIONS: TiC-Onco risk score performed significantly better than Khorana score at identifying cancer patients at high risk of VTE who would benefit from personalised thromboprophylaxis.

AB - Assessment of macular thickness is important in the evaluation of various eye diseases. This study aimed to determine the influence of the optic disc-fovea distance (DFD) on macular thickness in myopic eyes. We determined the DFD and the macular thickness in 138 eyes from 138 healthy myopic subjects using the Cirrus HD-OCT. Correlation analysis and multiple linear regression were performed to determine the influence of DFD, axial length, disc area, and beta-PPA on macular thickness. To further remove the confounding effect of ocular magnification on the DFD and OCT scan area, a subgroup analysis was performed in eyes with a limited axial length range (24-25 mm). DFD was significantly correlated with both regional (central, inner, and outer ETDRS subfields) and overall average macular thickness at a Bonferroni corrected P value of 0.004 (r ranging from -0.27 to 0.47), except for the temporal outer (r = -0.15, P = 0.089) and inferior outer (r = -0.22, P = 0.011) macular thickness. In the multivariable analysis, DFD was significantly associated with the average inner and outer macular thickness, the central subfield thickness, and the overall macular thickness (all P < 0.001), independent of ocular magnification and other covariates. Our findings indicate that eyes with a greater DFD have a lower macular thickness. PMID- 29588516 TI - Market watch: Top drugs and companies by sales in 2017. PMID- 29588513 TI - Mediator complex (MED) 7: a biomarker associated with good prognosis in invasive breast cancer, especially ER+ luminal subtypes. AB - BACKGROUND: Mediator complex (MED) proteins have a key role in transcriptional regulation, some interacting with the oestrogen receptor (ER). Interrogation of the METABRIC cohort suggested that MED7 may regulate lymphovascular invasion (LVI). Thus MED7 expression was assessed in large breast cancer (BC) cohorts to determine clinicopathological significance. METHODS: MED7 gene expression was investigated in the METABRIC cohort (n = 1980) and externally validated using bc GenExMiner v4.0. Immunohistochemical expression was assessed in the Nottingham primary BC series (n = 1280). Associations with clinicopathological variables and patient outcome were evaluated. RESULTS: High MED7 mRNA and protein expression was associated with good prognostic factors: low grade, smaller tumour size, good NPI, positive hormone receptor status (p < 0.001), and negative LVI (p = 0.04) status. Higher MED7 protein expression was associated with improved BC-specific survival within the whole cohort and ER+/luminal subgroup. Pooled MED7 gene expression data in the external validation cohort confirmed association with better survival, corroborating with the protein expression. On multivariate analysis, MED7 protein was independently predictive of longer BC-specific survival in the whole cohort and Luminal A subtype (p < 0.001). CONCLUSIONS: MED7 is an important prognostic marker in BC, particularly in ER+luminal subtypes, associated with improved survival and warrants future functional analysis.

AB - Regulation of transcription is fundamental to the control of cellular gene expression and function. Although recent studies have revealed a role for the oncoprotein MYC in amplifying global transcription, little is known as to how the global transcription is suppressed. Here we report that SUMO and MYC mediate opposite effects upon global transcription by controlling the level of CDK9 sumoylation. On one hand, SUMO suppresses global transcription via sumoylation of CDK9, the catalytic subunit of P-TEFb kinase essential for productive transcriptional elongation. On the other hand, MYC amplifies global transcription by antagonizing CDK9 sumoylation. Sumoylation of CDK9 blocks its interaction with Cyclin T1 and thus the formation of active P-TEFb complex. Transcription profiling analyses reveal that SUMO represses global transcription, particularly of moderately to highly expressed genes and by generating a sumoylation-resistant CDK9 mutant, we confirm that sumoylation of CDK9 inhibits global transcription. Together, our data reveal that SUMO and MYC oppositely control global gene expression by regulating the dynamic sumoylation and desumoylation of CDK9.

AB - Diamond bulk irradiated with a free-electron laser pulse of 6100 eV photon energy, 5 fs duration, at the ~19-25 eV/atom absorbed doses, is studied theoretically on its way to warm dense matter state. Simulations with our hybrid code XTANT show disordering on sub-100 fs timescale, with the diffraction peak (220) vanishing faster than the peak (111). The warm dense matter formation proceeds as a nonthermal damage of diamond with the band gap collapse triggering atomic disordering. Short-living graphite-like state is identified during a few femtoseconds between the disappearance of (220) peak and the disappearance of (111) peak. The results obtained are compared with the data from the recent experiment at SACLA, showing qualitative agreement. Challenges remaining for the accurate modeling of the transition of solids to warm dense matter state and proposals for supplementary measurements are discussed in detail. PMID- 29588525 TI - Succinate-acetate permease from Citrobacter koseri is an anion channel that unidirectionally translocates acetate. AB - Acetate is an important metabolite in metabolism and cell signaling. Succinate Acetate Permease (SatP) superfamily proteins are known to be responsible for acetate transport across membranes, but the nature of this transport remains unknown. Here, we show that the SatP homolog from Citrobacter koseri (SatP_Ck) is an anion channel that can unidirectionally translocate acetate at rates of the order of ~107 ions/s. Crystal structures of SatP_Ck in complex with multiple acetates at 1.8 A reveal that the acetate pathway consists of four acetate binding sites aligned in a single file that are interrupted by three hydrophobic constrictions. The bound acetates at the four sites are each orientated differently. The acetate at the cytoplasmic vestibule is partially dehydrated, whereas those in the main pore body are fully dehydrated. Aromatic residues within the substrate pathway may coordinate translocation of acetates via anion pi interactions. SatP_Ck reveals a new type of selective anion channel and provides a structural and functional template for understanding organic anion transport. PMID- 29588528 TI - Impact of delay in early swallow screening on pneumonia, length of stay in hospital, disability and mortality in acute stroke patients. AB - BACKGROUND/OBJECTIVES: Early swallow screening, within 4 h of admission, is required for all acute stroke patients to commence nutritional support, as recommended. We evaluated the impact of delay in early swallow screening on outcomes in patients admitted with acute stroke. SUBJECTS/METHODS: Prospective cohort study of 1656 men (mean +/- SD age = 73.1y +/- 13.2) and 1653 women (79.3y +/- 13.0) admitted with stroke to hyperacute stroke units (HASUs) in Surrey. Logistic regression was used to assess the risk (adjusted for age, stroke severity and co-morbidities) of delay in swallow screening on pneumonia, length of stay (LOS) > 3 weeks in HASU or hospital, moderately severe to severe disability on discharge (modified Rankin scale score = 4-5) and mortality during admission. RESULTS: Compared with those who received swallow screening within 4 h of admission, a delay between 4 and 72 h was associated with greater risks of pneumonia: OR = 1.4 (95%CI:1.1-1.9, P = 0.022), moderately severe to severe disability on discharge: OR = 1.4 (1.1-1.7, P = 0.007) and a delay beyond 72 h was associated with even greater risks of pneumonia: OR = 2.3 (1.4-3.6, P < 0.001), prolonged LOS in HASU: OR = 1.7 (1.0-3.0, P = 0.047, median LOS = 6.2 vs. 14.7 days) and hospital: OR = 2.1-fold (1.3-3.4, P = 0.007, median LOS = 6.8 vs. 14.9 days), moderately severe to severe disability on discharge: OR = 2.5 (1.7 3.7, P < 0.001) and mortality: OR = 3.8 (2.5-5.6, P < 0.001). These risks persisted after excluding 103 patients who died within 72 h. CONCLUSIONS: Delay in early screening for swallow capacity in acute stroke patients is detrimental to outcomes, possibly due to delaying nutritional provision or through inappropriate feeding leading to aspiration. Routine early screening needs greater attention in HASUs. PMID- 29588529 TI - Malnutrition risk is associated with hypoglycemia among general population admitted to internal medicine units. Results from the MENU study. AB - BACKGROUND/OBJECTIVES: To examine the association between increased malnutrition risk upon admission, and the incidence of hypoglycemia among adult patients admitted to internal medicine units in Israel. SUBJECTS/METHODS: This was a cross sectional study, and included were all adult patients admitted to internal medicine units, regardless of reason for admission. The NRS2002 was used to for nutritional screening. All glucose measurements were obtained using an institutional blood glucose-monitoring system, which consisted of a point of care, automated glucometer, and an interactive database. Patients were categorized as hypoglycemic if they had at least one documented hypoglycemia (= <70 mg/dL) event during the hospitalization period. Blood chemistry measured at admission was also recorded. RESULTS: Included were 876 patients (mean age 70.0 +/- 17.3, 50.6% were males). Rate of positive malnutrition screen was 39.7% of the population. A total of 5.4% of the study population had at least one hypoglycemic event during hospitalization. Rate of diabetes mellitus did not differ between patients with or without hypoglycemia. A greater proportion of patients with hypoglycemia were at increased malnutrition risk compared to patients without documented hypoglycemic events (56.8% vs. 38.9%, p = 0.018). Patients who had hypoglycemia had higher NRS2002 scores for pre-hospitalization unintentional weight loss and reduced food consumed. In logistic regression analysis, increased malnutrition risk was associated with hypoglycemia occurrence (OR 1.982, 95% confidence interval 1.056-3.718, p = 0.033). Age, sex, and diabetes mellitus status did not affect the rate of hypoglycemia. CONCLUSIONS: Our data suggest increased malnutrition risk as measured by the NRS2002 almost doubled the risk for hypoglycemia during the hospitalization.

Therefore, we aimed to describe knowledge and behaviors related to salt intake in Mozambique. SUBJECTS/METHODS: A cross sectional evaluation of a representative sample of the population aged 15-64 years (n = 3116) was conducted in 2014/2015, following the Stepwise Approach to Chronic Disease Risk Factor Surveillance, including a 12-question module for evaluation of dietary salt. RESULTS: Three dimensions were identified in the questionnaire, named "self-reported salt intake", "knowledge of health effects of salt intake", and "behaviors for control of salt intake". A total of 7.4% of the participants perceived that they consumed too much/far too much salt and 25.9% reported adding salt/salty seasoning often/always to prepared foods. The proportion considering that it was not important to decrease the salt contents of their diet was 8%, and 16.9% were not aware that high salt intake could be deleterious for health. Prevalences of lack of behaviors for reducing salt intake ranged from 74.9% for not limiting consumption of processed foods, to 95% for not buying low salt alternatives. There were few differences according to socio demographic variables, but awareness of hypertension was, in general, associated with better knowledge and less frequent behaviors likely to contribute to a high salt intake. CONCLUSIONS: Most Mozambicans were aware that high salt intake can cause health problems, but the self-reported salt intake and behaviors for its control show an ample margin for improvement. This study provides evidence to guide population level salt-reducing policies. PMID- 29588531 TI - Review of case reports on hyperkalemia induced by dietary intake: not restricted to chronic kidney disease patients. AB - Hyperkalemia is a metabolic disturbance of the potassium balance that can cause potentially fatal cardiac arrhythmias. Kidney dysfunction and renin-angiotensin aldosterone system inhibiting drugs are notorious for their tendency to induce hyperkalemia by decreasing the excretion of potassium. The role of dietary potassium intake in inducing hyperkalemia is less clear. We review and analyze the common presentation, laboratory, and electrocardiogram (ECG) findings and therapeutic options associated with dietary-induced hyperkalemia, and find evidence for hyperkalemia development in non-renal impaired patients. Thirty-five case reports including 44 incidences of oral intake-induced hyperkalemia were assessed, 17 patients did not suffer from kidney dysfunction. Mean age was 49 +/- 20 years. Mean potassium concentration was 8.2 +/- 1.4 mEq/l, most frequently caused by abundant intake of fruit and vegetables (n = 17) or salt substitutes (n = 12). In patients with normal kidney function, intake of salt substitutes or supplements was the main cause of hyperkalemia. Main symptoms encompassed muscle weakness (29.5%), vomiting (20.4%), and dyspnea (15.9%). When ECGs were performed (n = 30), abnormalities were present in 86.7% of cases. Treatment involved administration of insulin (n = 22), sodium/calcium polystyrene sulfonate (n = 14), and/or calcium gluconate (n = 14). Forty patients fully recovered. Three, non-renal impaired, patients passed away. These results offer insight into the clinical aspects of dietary-induced hyperkalemia and suggest that the common assumption that dietary-induced hyperkalemia is a condition of renal impaired patients might be incorrect. PMID- 29588532 TI - Molecular changes preceding endometrial and ovarian cancer: a study of consecutive endometrial specimens from Lynch syndrome surveillance. AB - Molecular alterations preceding endometrial and ovarian cancer and the sequence of events are unknown. Consecutive specimens from lifelong surveillance for Lynch syndrome provides a natural setting to address such questions. To molecularly define the multistep gynecological tumorigenesis, DNA mismatch repair gene mutation carriers with endometrial or ovarian carcinoma or endometrial hyperplasia were identified from a nation-wide registry and endometrial biopsy specimens taken from these individuals during 20 years of screening were collected. A total of 213 endometrial and ovarian specimens from Lynch syndrome individuals and 197 histology-matched (non-serous) samples from sporadic cases were available for this investigation. The specimens were profiled for markers linked to endometrial and ovarian tumorigenesis, including ARID1A protein expression, mismatch repair status, and tumor suppressor gene promoter methylation. In Lynch syndrome-associated endometrial and ovarian carcinomas, ARID1A protein was lost in 61-100% and mismatch repair was deficient in 97-100%, compared to 0-17% and 14-44% in sporadic cases (P = 0.000). ARID1A loss appeared in complex hyperplasia and deficient mismatch repair and tumor suppressor gene promoter methylation in histologically normal endometrium. Despite quantitative differences between Lynch syndrome and sporadic cases, ARID1A expression, mismatch repair, and tumor suppressor gene promoter methylation divided endometrial samples from both patient groups into three categories of increasing abnormality, comprising normal endometrium and simple hyperplasia (I), complex hyperplasia with or without atypia (II), and endometrial cancer (III). Complex hyperplasias without vs. with atypia were molecularly indistinguishable. In conclusion, surveillance specimens from Lynch syndrome identify mismatch repair deficiency, tumor suppressor gene promoter methylation, and ARID1A loss as early changes in tumor development. Our findings are clinically relevant for the classification of endometrial hyperplasias and have potential implications in cancer prevention in Lynch syndrome and beyond.

AB - Campylobacter jejuni infections are a leading cause of bacterial food-borne diarrhoeal illness worldwide, and Campylobacter infections in children are associated with stunted growth and therefore long-term deficits into adulthood. Despite this global impact on health and human capital, how zoonotic C. jejuni responds to the human host remains unclear. Unlike other intestinal pathogens, C. jejuni does not harbour pathogen-defining toxins that explicitly contribute to disease in humans. This makes understanding Campylobacter pathogenesis challenging and supports a broad examination of bacterial factors that contribute to C. jejuni infection. Here, we use a controlled human infection model to characterize C. jejuni transcriptional and genetic adaptations in vivo, along with a non-human primate infection model to validate our approach. We found that variation in 11 genes is associated with either acute or persistent human infections and includes products involved in host cell invasion, bile sensing and flagella modification, plus additional potential therapeutic targets. In particular, a functional version of the cell invasion protein A (cipA) gene product is strongly associated with persistently infecting bacteria and we identified its biochemical role in flagella modification. These data characterize the adaptive C. jejuni response to primate infections and suggest therapy design should consider the intrinsic differences between acute and persistently infecting bacteria. In addition, RNA sequencing revealed conserved responses during natural host commensalism and human infections. Thirty-nine genes were differentially regulated in vivo across hosts, lifestyles and C. jejuni strains. This conserved in vivo response highlights important C. jejuni survival mechanisms such as iron acquisition and evasion of the host mucosal immune response. These advances highlight pathogen adaptability across host species and demonstrate the utility of multidisciplinary collaborations in future clinical trials to study pathogens in vivo.

AB - G-protein signalling pathways are involved in sensing the environment, enabling fungi to coordinate cell function, metabolism and development with their surroundings, thereby promoting their survival, propagation and virulence. G protein-coupled receptors (GPCRs) are the largest class of cell surface receptors in fungi. Despite the apparent importance of GPCR signalling to fungal biology and virulence, relatively few GPCR-G-protein interactions, and even fewer receptor-binding ligands, have been identified. Approximately 40% of current pharmaceuticals target human GPCRs, due to their cell surface location and central role in cell signalling. Fungal GPCRs do not belong to any of the mammalian receptor classes, making them druggable targets for antifungal development. This Review Article evaluates developments in our understanding of fungal GPCR-mediated signalling, while substantiating the rationale for considering these receptors as potential antifungal targets. The need for insights into the structure-function relationship of receptor-ligand interactions is highlighted, which could facilitate the development of receptor-interfering compounds that could be used in disease control. PMID- 29588542 TI - Human cytomegalovirus reprogrammes haematopoietic progenitor cells into immunosuppressive monocytes to achieve latency. AB - The precise cell type hosting latent human cytomegalovirus (HCMV) remains elusive. Here, we report that HCMV reprogrammes human haematopoietic progenitor cells (HPCs) into a unique monocyte subset to achieve latency. Unlike conventional monocytes, this monocyte subset possesses higher levels of B7-H4, IL 10 and inducible nitric oxide synthase (iNOS), a longer lifespan and strong immunosuppressive capacity. Cell sorting of peripheral blood from latently infected human donors confirms that only this monocyte subset, representing less than 0.1% of peripheral mononuclear cells, is HCMV genome-positive but immediate early-negative. Mechanistic studies demonstrate that HCMV promotes the differentiation of HPCs into this monocyte subset by activating cellular signal transducer and activator of transcription 3 (STAT3). In turn, this monocyte subset generates a high level of nitric oxide (NO) to silence HCMV immediate early transcription and promote viral latency. By contrast, the US28-knockout HCMV mutant, which is incapable of activating STAT3, fails to reprogramme the HPCs and achieve latency. Our findings reveal that via activating the STAT3-iNOS NO axis, HCMV differentiates human HPCs into a longevous, immunosuppressive monocyte subset for viral latency. PMID- 29588543 TI - Urinary CE-MS peptide marker pattern for detection of solid tumors. AB - Urinary profiling datasets, previously acquired by capillary electrophoresis coupled to mass-spectrometry were investigated to identify a general urinary marker pattern for detection of solid tumors by targeting common systemic events associated with tumor-related inflammation. A total of 2,055 urinary profiles were analyzed, derived from a) a cancer group of patients (n = 969) with bladder, prostate, and pancreatic cancers, renal cell carcinoma, and cholangiocarcinoma and b) a control group of patients with benign diseases (n = 556), inflammatory diseases (n = 199) and healthy individuals (n = 331). Statistical analysis was conducted in a discovery set of 676 cancer cases and 744 controls. 193 peptides differing at statistically significant levels between cases and controls were selected and combined to a multi-dimensional marker pattern using support vector machine algorithms. Independent validation in a set of 635 patients (293 cancer cases and 342 controls) showed an AUC of 0.82. Inclusion of age as independent variable, significantly increased the AUC value to 0.85. Among the identified peptides were mucins, fibrinogen and collagen fragments. Further studies are planned to assess the pattern value to monitor patients for tumor recurrence. In this proof-of-concept study, a general tumor marker pattern was developed to detect cancer based on shared biomarkers, likely indicative of cancer-related features.

PMID- 29588546 TI - The AP-1-BATF and -BATF3 module is essential for growth, survival and TH17/ILC3 skewing of anaplastic large cell lymphoma. AB - Transcription factor AP-1 is constitutively activated and IRF4 drives growth and survival in ALK+ and ALK- anaplastic large cell lymphoma (ALCL). Here we demonstrate high-level BATF and BATF3 expression in ALCL. Both BATFs bind classical AP-1 motifs and interact with in ALCL deregulated AP-1 factors. Together with IRF4, they co-occupy AP-1-IRF composite elements, differentiating ALCL from non-ALCL. Gene-specific inactivation of BATFs, or global AP-1 inhibition results in ALCL growth retardation and/or cell death in vitro and in vivo. Furthermore, the AP-1-BATF module establishes TH17/group 3 innate lymphoid cells (ILC3)-associated gene expression in ALCL cells, including marker genes such as AHR, IL17F, IL22, IL26, IL23R and RORgammat. Elevated IL-17A and IL-17F levels were detected in a subset of children and adolescents with ALK+ ALCL. Furthermore, a comprehensive analysis of primary lymphoma data confirms TH17-, and in particular ILC3-skewing in ALCL compared with PTCL. Finally, pharmacological inhibition of RORC as single treatment leads to cell death in ALCL cell lines and, in combination with the ALK inhibitor crizotinib, enforces death induction in ALK+ ALCL. Our data highlight the crucial role of AP-1/BATFs in ALCL and lead to the concept that some ALCL might originate from ILC3. PMID- 29588549 TI - 'When Right could be so Wrong'.

PMID- 29588551 TI - Hip Hemi-Arthroplasty vs Total Hip Replacement for Displaced Intra-Capsular Hip Fractures: Retrospective Age and Sex Matched Cohort Study. AB - Introduction: The Royal Victoria Hospital in Belfast is the largest volume hospital in the UK Hip Fracture Database. Management of displaced intra-capsular hip fractures is evolving in light of NICE2 and BOA guidelines3, with more patients receiving total hip replacement (THR) over hemi-arthroplasty. With current rationing within the NHS, it is vital that principles of the 'Getting It Right First time' (GIRFT) report4 are implemented and the correct treatment choice made. Our aim was to assess Barthel scores5, complication rate, blood transfusion rate and post op functional ability in two age and sex matched cohorts to see if our patient selection was appropriate. Methods: Between January and December 2013, 2 age and sex matched cohorts each containing 46 hip fracture patients were retrospectively identified. The first group underwent Hip Hemi Arthroplasty (HHA) and the second group underwent THR. We looked at complication rate, blood transfusion rate, pre- and post-operative locomotor ability as well as Barthel score5. Results: Average age in the HHA group was 69.7 with an average ASA grade of 2.61, compared to 71.2 and 2.43 respectively in the THR group. Complication rate in the HHA group was 45.6% with 2/3 due to chest sepsis or urosepsis. The THR group had a complication rate of 8.7% with 3/4 due to venous thrombembolism, reflecting the better pre-morbid physiological function in this cohort. Blood transfusion rates were similar in both groups. Barthel scores5 showed average reductions of 2.67 in the HHA group and 0.30 in the THR group. Conclusions: The application of the NICE guidelines2 for arthroplasty choice in hip fracture management has led to judicious patient selection for THR. The THR group had a significantly lower complication rate (p<0.05) and better Barthel scores5 (p<0.05) compared to the HHA group. In addition, having a higher ASA score (III or IV) or lower Barthel score5 pre-operatively were independent predictors of complication occurrence. PMID- 29588552 TI - ESCAPE to Reality, Post-Trial Outcomes in an ESCAPE Centre: A Retrospective Case Control Study. AB - Introduction: The Royal Victoria Hospital, Belfast provides the regional neuroendovascular service for Northern Ireland and was an enrolling centre for the ESCAPE endovascular stroke trial. Our aim was to assess outcomes for patients presenting with acute stroke following discontinuation of trial enrolment at our centre. Methods: We collected data on all patients presenting with acute stoke between Nov-1st-2014 and Oct-31st-2015 who received endovascular treatment or received IV thrombolysis (IV-tPA) alone. ESCAPE eligibility of each patient was assessed. Primary outcome was modified Rankin Score (mRS) at 3 months. Results: 129 patients presented with acute stoke symptoms during the time period; 56/129 (43.4%) patients in the intervention group and 73/129 (56.5%) patients in the control group. In the interventional group, 42/56 (75%) were considered ESCAPE eligible and 14/56 (25%) were considered ESCAPE ineligible. 30/42 (71.4%) ESCAPE eligible patients had a positive functional outcome at 3 months compared to 9/14 (64.2%) ESCAPE ineligible patients. In the control group, 37 (50.7%) had identifiable thrombotic occlusion and 13/37 (35.1%) were considered eligible for intervention. 4/13 (30.8%) achieved functional independence (mRS<3) at 3 months.There was a statistically significant difference in functional independence in those who underwent endovascular therapy compared to the control group (p= 0.04). Conclusion: ESCAPE eligible patients in our centre had favourable outcome rates superior to the published trial data. ESCAPE ineligible patients tended to do slightly less well, but still better than the favourable outcome rates achieved with IVtPA alone. There is potentially a wide discordance between the threshold for futility and trial eligibility criteria when considering endovascular treatment for acute ischaemic stroke. PMID- 29588553 TI - Age adjusted D-dimer in the Belfast Health and Social Care Trust: A retrospective study. AB - D-dimers combined with clinical pre-test probability (PTP) scores are used to determine the likelihood of a venous thromboembolic event (VTE). It is recognised that with advancing age, d-dimer values increase, leading to a cohort of patients with a d-dimer above the standard cut-off of 500MUg/L. A recent systemic review, examined the accuracy of an age-adjusted D-dimer in those aged > 50 years with a low clinical risk of a VTE. This showed an increase in specificity without loss of sensitivity. Our study, aimed to examine a population of patients, who between 2011 and 2014 underwent ultrasound Doppler studies of lower limbs. By applying a corresponding age-adjusted D-dimer, we determined the sensitivity and specificity and compared this to use of conventional D-dimer.

PMID- 29588555 TI - Insulin Autoimmune Syndrome: a rare case of hypoglycaemia resolving with immunosuppression. AB - We report a case of a 58-year-old male presenting with confusion and hypoglycaemia. There had been no prior exposure to oral hypoglycaemic agents or insulin. He was found to have inappropriate endogenous hyperinsulinaemia. Insulinoma was excluded by detailed endocrine assessment. Insulin antibodies were positive in keeping with a diagnosis of insulin autoimmune syndrome (IAS). He was treated with prednisolone 5mg once daily and nutritional supplements leading to resolution of acute confusion and hypoglycaemic episodes. The patient also had severe psoriasis and following discharge was treated with a variety of immunosuppressant therapies. This was associated with disappearance of insulin antibodies after twelve months of follow up. While it is possible that there was spontaneous resolution of insulin antibodies, we speculate that his prednisolone and immunosuppressant therapy may have suppressed insulin antibody production. There are several well recognised associations with IAS and autoimmune conditions, including Grave's disease, systemic lupus erythematous and rheumatoid arthritis. To our knowledge this is the first reported case of insulin autoimmune syndrome, resolving with immunosuppressant treatment of psoriasis.

AB - Introduction: There is a growing research interest in how healthcare professionals learn online. This paper reports an analysis of reflections that relate to patients from users of an e-learning resource, BMJ Learning. Methods: Healthcare professionals who use BMJ Learning are encouraged to reflect on their learning. Over one year, all of the learners' reflections that related to patients were captured by the programme's software and were analysed using thematic analysis. Results: A number of key themes emerged from this analysis: many learners reflected on patients in the context of their disease; many learners reflected on how they had put their learning into action or planned to put their learning into action for the benefit of patients; many learners reflected on how they would pass on what they had learned to patients; learners greatly appreciated patients contributing to the learning. Discussion: Learners predominantly reflect about patients in the context of their disease. The reflections demonstrate that learners are keen to put their learning into action for the benefit of their patients. Learners' reflections show a keen interest in the patient-centredness of the learning resources. PMID- 29588559 TI - CHRONIC RING EROSION OF A FINGER.

PMID- 29588569 TI - In vivo assessment of changes in corneal hysteresis and lamina cribrosa position during acute intraocular pressure elevation in eyes with markedly asymmetrical glaucoma. AB - Purpose: To investigate the biomechanical response of the cornea, lamina cribrosa (LC), and prelaminar tissue (PT) to an acute intraocular pressure (IOP) increase in patients with markedly asymmetrical glaucoma and in healthy controls. Patients and methods: A total of 24 eyes of 12 patients with markedly asymmetrical primary open-angle glaucoma (POAG) and 12 eyes of 12 healthy patients were examined with spectral-domain optical coherence tomography (SD-OCT) and ocular response analyzer (ORA) at baseline and during acute IOP elevation by means of an ophthalmodynamometer. The displacement of the LC and PT and the change in corneal hysteresis (CH) and corneal resistance factor (CRF) were evaluated. Results: Following a mean IOP increase of 12.3+/-2.4 mmHg, eyes with severe glaucoma demonstrated an overall mean anterior displacement of the LC (-6.58+/-26.09 um) as opposed to the posterior laminar displacement in eyes with mild glaucoma (29.08+/-19.28 um) and in healthy eyes (30.3+/-10.9; p<=0.001 and p=0.001, respectively). The PT displaced posteriorly during IOP elevation in all eyes. The CH decreased in eyes with severe glaucoma during IOP elevation (from 9.30+/-3.65 to 6.92+/-3.04 mmHg; p=0.012), whereas the CRF increased markedly in eyes with mild glaucoma (from 8.61+/-2.30 to 12.38+/-3.64; p=0.002) and in eyes with severe glaucoma (from 9.02+/-1.48 to 15.20+/-2.06; p=0.002). The increase in CRF correlated with the anterior displacement of the LC in eyes with severe glaucoma. Conclusion: Eyes with severe glaucoma exhibited a mean overall anterior displacement of the anterior laminar surface, while eyes with mild glaucoma and healthy eyes showed a posterior displacement of the LC during IOP elevation. The CH decreased significantly from baseline only in eyes with severe glaucoma, but the CRF increased significantly in all glaucomatous eyes. The CRF increase correlated with the anterior displacement of the LC in eyes with severe glaucoma. PMID- 29588570 TI - Pneumatic retinopexy: patient selection and specific factors. AB - Pneumatic retinopexy is a minimally invasive, non-incisional procedure for repairing retinal detachment. This procedure is associated with reduced morbidity, reduced cost and faster postoperative recovery compared to pars plana vitrectomy and scleral buckling. Superior visual acuity outcomes have also been reported. Intraoperative complications are primarily related to the intraocular pressure rise caused by gas injection, or the misdirection of the gas. There is a low rate of postoperative complications. Anatomic success rates of over 90% can be achieved when strict selection criteria are applied. However, a number of studies have revealed good outcomes in cases with expanded clinical indications. Pneumatic retinopexy is currently underutilized. With appropriate patient selection, a high success rate can be achieved, and therefore, this procedure has an important role in the armamentarium of the vitreoretinal surgeon. PMID- 29588571 TI - Comparisons of foveal thickness and slope after macular hole surgery with and without internal limiting membrane peeling. AB - Background: We have shown that the foveal contour was asymmetrical after idiopathic macular hole (MH) closure by pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling. The purpose of this study was to determine whether these morphological changes differ in eyes after PPV without ILM peeling. Methods: Ten eyes of 10 patients that underwent PPV without ILM peeling and 12 eyes of 11 patients with ILM peeling were studied. The MH in all eyes was <400 um in diameter. Six months after the PPV, the macular thickness and foveal slope around the closed MH were determined by spectral-domain optical coherence tomography. The thickness of the ganglion cell complex was measured by another spectral-domain optical coherence tomography instrument >6 months after the surgery. Results: The mean parafoveal retinal thickness in the non-peeled group was 367.1 um in the nasal (N), 353.0 um in the temporal (T), 366.9 um in the superior (S), and 357.3 um in the inferior (I) sectors. The T, S, and I sectors were significantly thicker than the corresponding sectors in the ILM peeled group (p=0.0008, 0.003, and 0.03, respectively). The mean ganglion cell complex was thicker not only in the N sector but also in the T sector in the non-peeled group. The mean retinal slopes in the non-peeled group (N, 40.2 degrees ; T, 37.6 degrees ; S, 41.2 degrees ; I, 39.5 degrees ) were flatter than those in the peeled group (N, 52.3 degrees ; T, 43.6 degrees ; S, 50.8 degrees ; I, 51.9 degrees ; p=0.009, 0.09, 0.008, and 0.017, respectively). Conclusion: The symmetrical fovea after MH surgery in the non-ILM peeled eyes indicates that the asymmetrical fovea after ILM peeling was probably due to the ILM peeling. PMID- 29588572 TI - Effect of tocotrienol from Bixa orellana (annatto) on bone microstructure, calcium content, and biomechanical strength in a model of male osteoporosis induced by buserelin. AB - Background: Patients receiving androgen deprivation therapy experience secondary hypogonadism, associated bone loss, and increased fracture risk. It has been shown that tocotrienol from Bixa orellana (annatto) prevents skeletal microstructural changes in rats experiencing primary hypogonadism. However, its potential in preventing bone loss due to androgen deprivation therapy has not been tested. This study aimed to evaluate the skeletal protective effects of annatto tocotrienol using a buserelin-induced osteoporotic rat model. Methods: Forty-six male Sprague Dawley rats aged 3 months were randomized into six groups. The baseline control (n=6) was sacrificed at the onset of the study. The normal control (n=8) received corn oil (the vehicle of tocotrienol) orally daily and normal saline (the vehicle of buserelin) subcutaneously daily. The buserelin control (n=8) received corn oil orally daily and subcutaneous buserelin injection (75 ug/kg) daily. The calcium control (n=8) was supplemented with 1% calcium in drinking water and daily subcutaneous buserelin injection (75 ug/kg). The remaining rats were given daily oral annatto tocotrienol at 60 mg/kg (n=8) or 100 mg/kg (n=8) plus daily subcutaneous buserelin injection (75 ug/kg) (n=8). At the end of the experiment, the rats were euthanized and their blood, tibia, and femur were harvested. Structural changes of the tibial trabecular and cortical bone were examined using X-ray micro-computed tomography. Femoral bone calcium content and biomechanical strength were also evaluated. Results: Annatto tocotrienol at 60 and 100 mg/kg significantly prevented the deterioration of trabecular bone and cortical thickness in buserelin-treated rats (P<0.05). Both doses of annatto tocotrienol also improved femoral biomechanical strength and bone calcium content in buserelin-treated rats (P<0.05). The effects of annatto tocotrienol were comparable to calcium supplementation. Conclusion: Annatto tocotrienol supplementation is effective in preventing degeneration of the bone induced by buserelin. Therefore, it is a potential antiosteoporotic agent for men receiving androgen deprivation therapy. PMID- 29588574 TI - Application of health quotient to enhance chronic periodontitis treatments. AB - Objectives: Based on the concept of health quotient (HQ), we designed and facilitated personalized plans to improve patients' compliance and oral health. The study aims to increase HQ level of patients with chronic periodontitis from four aspects, namely self-care, health knowledge, lifestyle, and mental health, and evaluate the effects of HQ training in maintaining oral health. Method: In total, 105 patients with chronic periodontitis were recruited from Capital Medical University-Affiliated Beijing Chaoyang Hospital from January 2015 to January 2017. The patients were randomly split into two groups (control versus test). All the patients received standard periodontal treatments. In addition, patients in the control group received conventional oral health instructions, and patients in the test group received the HQ training. At the end of the training, oral health status of both groups was evaluated and recorded. Results: The oral health status and the HQ scores were significantly better in the test group than the control group (P<0.01). The training in HQ provided a better guidance for patients in oral health maintenance and further improved patients' compliance. Conclusion: HQ training for patients with chronic periodontitis increased their scores in self-care and health knowledge and significantly slowed down the progression of chronic periodontitis. PMID- 29588573 TI - Vitexin protects dopaminergic neurons in MPTP-induced Parkinson's disease through PI3K/Akt signaling pathway. AB - : Parkinson's disease (PD) is a progressive neurodegenerative disease which is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc). Methods: In this study, the neuroprotective effect of vitexin (Vit), a flavonoid compound isolated from Crataegus pinnatifida Bunge was examined in PD models both in vitro and in vivo. Results: On SH-SY5Y cells, methyl-4-phenylpyridine (MPP+) treatment suppressed cell viability, induced apoptosis, and increased Bax/Bcl-2 ratio and caspase-3 activity. However, Vit improved these parameters induced by MPP+ treatment significantly. Further study disclosed that Vit enhanced the phosphorylation of PI3K and Akt which was downregulated by MPP+ in SH-SY5Y cells, the effect of which could be blocked by PI3K inhibitor LY294002 and activated by PI3K activator IGF-1. Moreover, results from the pole test and traction test suggested that Vit pretreatment prevented bradykinesia and alleviated the initial lesions caused by 1-methyl-4-phenyl 1,2,3,6-tetrahydropyridine (MPTP) in MPTP-treated mouse PD model. Vit also enhanced the activation of PI3K and Akt and suppressed the ratio of Bax/Bcl-2 and caspase-3 activity in MPTP-treated mice. Conclusion: Taken together, this study demonstrated that Vit protected dopaminergic neurons against MPP+/MPTP-induced neurotoxicity through the activation of PI3K/Akt signaling pathway. Our findings may facilitate the clinical application of Vit in the therapy of PD.

AB - Background: Psoriasis affects different aspects of health-related quality of life (eg, physical, psychological, and social impairments); these health domains can be of different importance for patients. The importance of domains can be measured with the Patient Benefit Index (PBI). This questionnaire weights the achievement of treatment goals by Likert scales (0, "not important at all" to 4, "very important") using the Patient Needs Questionnaire (PNQ). Treatment goals assessed with the PBI have been assigned to five health domains; the importance of each domain can be calculated as the average importance of the respective treatment goals. In this study, the PBI approach of deriving importance weights is contrasted to a discrete choice experiment (DCE), in order to determine the importance of health domains in psoriasis, and to find if the resulting weights will differ when derived from these two methods. Methods: Adult patients with psoriasis completed both questionnaires (PNQ, DCE). The PBI domains were used as attributes in the DCE with the levels "did not help at all", "helped moderately", and "helped a lot". Results: Using DCE, "improving physical functioning" was the most important health domain, followed by "improving psychological well-being". Using PNQ, these domains were ranked in position two and three following "strengthening confidence in the therapy and in a possible healing". The latter was least important using DCE. The only agreement of ranking was shown in "reducing impairments due to therapy" (position four). "Improving social functioning" was ranked in position three (DCE) and five (PNQ). Conclusion: Health domains have different importance to patients with psoriasis. Using PNQ or DCE to determine the importance of domains results in markedly different rankings; both approaches can thus not be considered equivalent. However, in this study, importance was assessed at the domain level in DCE and at the single item level in PNQ, which may have added to the differences. PMID- 29588577 TI - The level of awareness and the attitude of patients recommended for use of compression stockings in Turkish society, and investigation of the factors affecting their use. AB - Objective: The purpose of this study was to reveal the treatment outlook, usage habits, and factors affecting these habits, in addition to providing suggestions for solutions for patients who are frequently recommended the use of compression stockings as treatment for conditions such as chronic venous insufficiency, deep vein thrombosis, lymphedema, and pregnancy. Methods: The study was conducted as a face-to-face questionnaire session with 1,004 patients who had previously registered at the cardiovascular surgeon's polyclinic of Sivas Numune Hospital between March 29, 2017, and October 31, 2017. In the study, basic criteria such as the patients' history, physical examination findings, and the use of compression stockings were evaluated. The survey was conducted in patients who were recommended compression stockings treatment for conditions such as chronic venous insufficiency, deep vein thrombosis, lymphedema, or pregnancy. The patients were asked about their demographics, characteristics of the compression stockings, whether compression stockings were used or not, and doctor evaluations related to the diagnosis. Results: At the end of the study, it was found that 20.5% of the patients who were recommended compression stockings never bought them and only 11.5% of the patients regularly used them. Another surprising detail was that only 54.7% of the patients thought that the compression stockings were part of the treatment and 44.0% of the patients thought that they would benefit from using them. Conclusion: In many guidelines, use of compression stockings is the cornerstone of treatment of venous diseases. However, when the treatment incompatibility of the patients is taken into account, many duties fall to the doctors. The first of these is to inform the patient about the treatment and to answer any questions from the patients. In addition, the socioeconomic and sociocultural status of patients should be considered by the doctors. PMID- 29588576 TI - A 4-year non-randomized comparative phase-IV study of early rheumatoid arthritis: integrative anthroposophic medicine for patients with preference against DMARDs versus conventional therapy including DMARDs for patients without preference. AB - Background: While disease-modifying antirheumatic drugs (DMARDs) are a mainstay of therapy for rheumatoid arthritis (RA), some patients with early RA refuse DMARDs. In anthroposophic medicine (AM), a treatment strategy for early RA without DMARDs has been developed. Preliminary data suggest that RA symptoms and inflammatory markers can be reduced under AM, without DMARDs. Patients and methods: Two hundred and fifty-one self-selected patients aged 16-70 years, starting treatment for RA of <3 years duration, without prior DMARD therapy, participated in a prospective, non-randomized, comparative Phase IV study. C patients were treated in clinics offering conventional therapy including DMARDs, while A-patients had chosen treatment in anthroposophic clinics, without DMARDs. Both groups received corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). Primary outcomes were intensity of RA symptoms measured by self-rating on visual analog scales, C-reactive protein, radiological progression, study withdrawals, serious adverse events (SAE), and adverse drug reactions in months 0 48. Results: The groups were similar in most baseline characteristics, while A patients had longer disease duration (mean 15.1 vs 10.8 months, p<0.0001), slightly more bone destruction, and a much higher proportion of women (94.6% vs 69.7%, p<0.0001). In months 0-12, corticosteroids were used by 45.7% and 81.6% (p<0.0001) and NSAIDs by 52.8% and 68.5% (p=0.0191) of A- and C-patients, respectively. During follow-up, both groups not only had marked reduction of RA symptoms and C-reactive protein, but also some radiological disease progression. Also, 6.2% of A-patients needed DMARDs. Apart from adverse drug reactions (50.4% and 69.7% of A- and C-patients, respectively, p=0.0020), none of the primary outcomes showed any significant between-group difference. Conclusion: Study results suggest that for most patients preferring anthroposophic treatment, satisfactory results can be achieved without use of DMARDs and with less use of corticosteroids and NSAIDs than in conventional care. Limitation: Because of the non-randomized study design, with A-patients choosing anthroposophic treatment, one cannot infer how this treatment would have worked for C-patients. PMID- 29588578 TI - Investigating the role of perception of aging and associated factors in death anxiety among the elderly. AB - Background and objectives: The world's growing elderly population highlights the necessity for further attention to the psychological problems of the elderly, such as death anxiety. Analysis of the elderly's perception of aging and associated factors can contribute to prediction of their future physical and mental health. The purpose of this study was to determine the relationship of perception of aging, and a group of demographic factors, with death anxiety in the elderly living in Gonabad, Iran. Subjects and methods: This analytical descriptive study was conducted on 330 elderly residents of Gonabad, who were selected by stratified random sampling. Research tools were a standard demographic questionnaire, Barker's Brief Aging Perceptions Questionnaire, and Collett-Lester Fear of Death Scale. Data were collected by interview of respondents at their home. Data analysis was carried out in SPSS 16 using descriptive statistics, analysis of variance, Pearson's test, independent t-test, and linear regression. Results: Respondents had a mean age of 73.97+/-7.68 years, 42.4% of respondents were men and 57.6% were women. The total Barker's Brief Aging Perceptions Questionnaire score was 63.18+/-8.75, with the highest score (17.10+/-4.70) associated with negative consequences and control. The total Collett-Lester Fear of Death Scale score was 128+/-14.80, with the highest score (35.13+/-4.06) pertaining to the subscale fear of other people's death. Regression results indicated that the death anxiety score was predictable according to the age and all dimensions of perception of aging, except for the consequences and negative control dimension. Conclusion: Age and the perception of aging are good predictors of death anxiety. The authors recommend further research on the determinants of death anxiety in the elderly and the development of a comprehensive care plan to reduce this anxiety among Iranian elderly. PMID- 29588579 TI - Resistance training-induced gains in muscle strength, body composition, and functional capacity are attenuated in elderly women with sarcopenic obesity. AB - Objectives: The purpose of this study was to compare the effects of resistance training (RT) on body composition, muscle strength, and functional capacity in elderly women with and without sarcopenic obesity (SO). Methods: A total of 49 women (aged >=60 years) were divided in two groups: without SO (non-SO, n=41) and with SO (n=8). Both groups performed a periodized RT program consisting of two weekly sessions for 16 weeks. All measures were assessed at baseline and postintervention, including anthropometry and body composition (dual-energy X-ray absorptiometry), muscle strength (one repetition maximum) for chest press and 45 degrees leg press, and functional capacity (stand up, elbow flexion, timed "up and go"). Results: After the intervention, only the non-SO group presented significant reductions in percentage body fat (-2.2%; P=0.006), waist circumference (-2.7%; P=0.01), waist-to-hip ratio (-2.3; P=0.02), and neck circumference (-1.8%; P=0.03) as compared with baseline. Muscle strength in the chest press and biceps curl increased in non-SO only (12.9% and 11.3%, respectively), while 45 degrees leg press strength increased in non-SO (50.3%) and SO (40.5%) as compared with baseline. Performance in the chair stand up and timed "up and go" improved in non-SO only (21.4% and -8.4%, respectively), whereas elbow flexion performance increased in non-SO (23.8%) and SO (21.4%). Effect sizes for motor tests were of higher magnitude in the non-SO group, and in general, considered "moderate" compared to "trivial" in the SO group. Conclusion: Results suggest that adaptations induced by 16 weeks of RT are attenuated in elderly woman with SO, compromising improvements in adiposity indices and gains in muscle strength and functional capacity. PMID- 29588580 TI - A functional SNP upstream of the ADRB2 gene is associated with COPD. AB - Background: Previous studies have suggested that beta2-adrenergic receptor (ADRB2) is associated with COPD. However, the role of genetic polymorphisms in ADRB2 on COPD has not been evaluated yet. Methods: In this study, SNaPshot genotyping, luciferase assay, chromatin immunoprecipitation and real-time polymerase chain reaction were adopted to investigate the association between ADRB2 genetic polymorphisms and COPD, comprehensively. Results: One single nucleotide polymorphism (rs12654778), located upstream of ADRB2, showed a significant association with COPD by the logistic regression analysis after adjusting for age, sex and smoking history (p=0.04) in 200 COPD patients and 222 controls from southwest Chinese population. Furthermore, the luciferase assay indicated that rs12654778-A allele reduced the relative promoter activity by ~26% compared with rs12654778-G allele (p=0.0034). The chromatin immunoprecipitation analysis demonstrated that rs12654778 modulated the binding affinity of transcription factor neurofibromin 1. In addition, a significantly reduced expression of ADRB2 in COPD patients was observed, compared with normal controls (p=0.017). Conclusion: Our findings suggest a previously unknown mechanism linking allele-specific effects of rs12654778 on ADRB2 expression to COPD onset, for the first time. PMID- 29588581 TI - Maintenance inhaler preference, attribute importance, and satisfaction in prescribing physicians and patients with asthma, COPD, or asthma-COPD overlap syndrome consulting for routine care. AB - Background: In respiratory disorders, patient- and physician-perceived satisfaction with the maintenance inhaler device is an important factor driving treatment compliance and outcomes. We examine inhaler preferences in asthma and COPD from patient and physician perspectives, particularly focusing on the relative importance of individual device attributes and patient characteristics guiding inhaler choice. Materials and methods: Real-world data from >7,300 patients with asthma, COPD, or asthma-COPD overlap syndrome (ACOS) consulting for routine care were derived from respiratory Disease Specific Programs conducted in Europe, USA, Japan, and China. Outcome variables included current pattern of inhaled maintenance therapy and device type, physician preference, patient reported device attribute importance, and satisfaction. Results: The most commonly prescribed inhalers for maintenance therapy of asthma, COPD, and ACOS were dry powder inhalers (62.8%-88.5% of patients) and pressurized metered dose inhalers (18.9%-35.3% of patients). One-third of physicians stated no preference for maintenance device when prescribing treatment, and less than one-third of patients reported being "extremely satisfied" with any attribute of their device. Instructions being "simple and easy to follow" was the inhaler attribute most commonly selected as important. For approximately one-third of patients across all groups, "ease of use/suitability of inhaler device" was a reason for the prescribing decision, as stated by the physician. Device characteristics were more likely to impact the prescribing decision in older patients (in asthma and COPD; P<0.01) and those with worse disease severity (in COPD; P<0.001). Conclusion: A relatively high proportion of physicians had no preference for inhaler type across asthma, COPD, and ACOS. Simplicity of use was the most important inhaler attribute from a patient's perspective. Physicians appeared to place most importance on ease of use and device suitability when selecting inhalers for older patients and those with more severe disease, particularly in COPD. PMID- 29588582 TI - Influence of luminescent graphene quantum dots on trypsin activity. AB - Background: Protein-graphene interactions have the potential to play a pivotal role in the future directions of nanomedicine. These interactions lead to diverse processes such as generation of protein coronas, nano-bio interfaces, particle wrapping, and biocatalytic processes that could determine the ultimate fate of graphene nanocomposites in biologic systems. However, such interactions and their effects on the bioavailability of graphene have not yet been widely appreciated, despite the fact that this is the primary surface in contact with cells. Methods: This paper reports on the integrative physiochemical interaction between trypsin and graphene quantum dots (GQDs) to determine their potential biologic identity in enzyme engineering. This interaction was measured by a wide range of analytical methods. Results: Definitive binding and modulation of trypsin-GQDs was demonstrated for the first time by use of vibrational spectroscopy and wetting transparency, which revealed that trypsin was absorbed on GQDs' surface through its cationic and hydrophilic residues. Our findings suggested that trypsin's active sites were stabilized and protected by the GQDs, which were likely to be responsible for the high bioavailability of GQDs in enzymes. Conclusion: Our work demonstrates the efficacy of GQDs as an enzyme modulator with high specificity, and their great application potential in enzyme engineering as well as enzyme-based therapies. PMID- 29588583 TI - siRNA-loaded selenium nanoparticle modified with hyaluronic acid for enhanced hepatocellular carcinoma therapy. AB - Background: Small interfering RNA (siRNA) as a new therapeutic modality holds promise for cancer treatment. However, the traditional viral carriers are prone to immunogenicity and risk of insertional mutagenesis. Methods: In order to provide a tumor-targeted delivery carrier of siRNA in cancer therapy, the hyaluronic acid (HA)-selenium (Se)-polyethylenimine (PEI) nanoparticle (NP) was fabricated by decorating SeNP with HA as a tumor-targeting moiety and by linking the polycationic polymers polyethylenimine PEI onto the surface of SeNP. The siRNA was loaded to the surface of SeNP HA-Se-PEI via the electrostatic interaction between siRNA and PEI to prepare the functionalized SeNP HA-Se PEI@siRNA. Results: The HA-Se-PEI@siRNA was internalized into the HepG2 cell mainly in a clathrin-mediated endocytosis manner. Owing to the active tumor targeted effect mediated by HA, HA-Se-PEI@siRNA achieved the obvious higher transfection efficiency, greater gene silencing ability, and stronger cytotoxicity in the HepG2 cell compared with the passive tumor-targeted NP Se PEI@siRNA. The knockdown of hairy and enhancer of split 5 by HA-Se-PEI@siRNA induced the HepG2 cell cycle arrest at the G0/G1 phase and apoptosis. Furthermore, the treatment with HA-Se-PEI@siRNA resulted in greater antitumor efficacy compared with the Se-PEI@siRNA in vitro and in vivo. In addition, the HA Se-PEI@siRNA was almost no toxic to the key organs of mice. Conclusion: These findings provided an alternative therapeutic route for targeted cancer treatments. PMID- 29588584 TI - A novel electrospun-aligned nanoyarn/three-dimensional porous nanofibrous hybrid scaffold for annulus fibrosus tissue engineering. AB - Introduction: Herniation of the nucleus pulposus (NP) because of defects in the annulus fibrosus (AF) is a well-known cause of low back pain. Defects in the AF thus remain a surgical challenge, and efforts have been made to develop new techniques for closure and repair. In this study, we developed an electrospun aligned nanoyarn scaffold (AYS) and nanoyarn/three-dimensional porous nanofibrous hybrid scaffold (HS) for AF tissue engineering. Methods: The AYS was fabricated via conjugated electrospinning, while the aligned nanofibrous scaffold (AFS) was prepared by traditional electrospinning as a baseline scaffold. The HS was constructed by freeze-drying and cross-linking methods. Scanning electron microscopy and mechanical measurement were used to characterize the properties of these scaffolds. Bone marrow derived mesenchymal stem cells (BMSCs) were seeded on scaffolds, and cell proliferation was determined by CCK-8 assay, while cell infiltration and differentiation were assessed by histological measurement and quantitative real-time polymerase chain reaction, respectively. Results: Morphological measurements showed that AYS presented a relatively better three dimensional structure with larger pore sizes, higher porosity, and better fibers' alignment compared to AFS. Mechanical testing demonstrated that the tensile property of AFS and AYS was qualitatively similar to the native AF tissue, albeit to a lesser extent. When BMSCs were seeded and cultured on these scaffolds, the number of cells cultured on HS and AYS was found to be significantly higher than that on AFS and culture plate after 7 days of culture (P<0.05). In addition, cell infiltration was significantly higher in HS when compared with AFS and AYS (P<0.05). A part of BMSCs ingressed into the inner part of AYS upon long-term in vitro culture. No significant difference was observed between AFS and AYS in terms of the median infiltration depth (P>0.05). BMSCs seeded on AYS demonstrated an increased expression of COL1A1, while the expression levels of SOX-9, COL2A1, and Aggrecan were higher in HS compared to other scaffolds (P<0.05). Conclusion: These findings indicate that HS makes a proper scaffold for the AF tissue engineering as it replicates the axial compression and tensile property of AF, thereby providing a better platform for cell infiltration and cell-scaffold interaction. PMID- 29588586 TI - Paclitaxel-loaded redox-sensitive nanoparticles based on hyaluronic acid-vitamin E succinate conjugates for improved lung cancer treatment. AB - Background: Lung cancer is the primary cause of cancer-related death worldwide. A redox-sensitive nanocarrier system was developed for tumor-targeted drug delivery and sufficient drug release of the chemotherapeutic agent paclitaxel (PTX) for improved lung cancer treatment. Methods: The redox-sensitive nanocarrier system constructed from a hyaluronic acid-disulfide-vitamin E succinate (HA-SS-VES, HSV) conjugate was synthesized and PTX was loaded in the delivery system. The physicochemical properties of the HSV nanoparticles were characterized. The redox sensitivity, tumor-targeting and intracellular drug release capability of the HSV nanoparticles were evaluated. Furthermore, in vitro and in vivo antitumor activity of the PTX-loaded HSV nanoparticles was investigated in a CD44 over expressed A549 tumor model. Results: This HSV conjugate was successfully synthesized and self-assembled to form nanoparticles in aqueous condition with a low critical micelle concentration of 36.3 MUg mL-1. Free PTX was successfully entrapped into the HSV nanoparticles with a high drug loading of 33.5% (w/w) and an entrapment efficiency of 90.6%. Moreover, the redox-sensitivity of the HSV nanoparticles was confirmed by particle size change of the nanoparticles along with in vitro release profiles in different reducing environment. In addition, the HA-receptor mediated endocytosis and the potency of redox-sensitivity for intracellular drug delivery were further verified by flow cytometry and confocal laser scanning microscopic analysis. The antitumor activity results showed that compared to redox-insensitive nanoparticles and Taxol(r), PTX-loaded redox sensitive nanoparticles exhibited much greater in vitro cytotoxicity and apoptosis-inducing ability against CD44 over-expressed A549 tumor cells. In vivo, the PTX-loaded HSV nanoparticles possessed much higher antitumor efficacy in an A549 mouse xenograft model and demonstrated improved safety profile. In summary, our PTX-loaded redox-sensitive HSV nanoparticles demonstrated enhanced antitumor efficacy and improved safety of PTX. Conclusion: The results of our study indicated the redox-sensitive HSV nanoparticle was a promising nanocarrier for lung cancer therapy. PMID- 29588587 TI - Targeted therapy of intracranial glioma model mice with curcumin nanoliposomes. AB - Background: Glioma is the most aggressive and lethal brain tumor in humans, it comprises about 30 per cent of all brain tumors and central nervous system tumors. Purpose: The objective of this study was to create novel brain-targeting nanoliposomes to encapsulate curcumin as a promising option for glioma therapy. Patients and methods: Human glioma cells (U251MG) were used to determine cell uptake efficiency and possible internalization mechanism of the curcumin-loaded nanoliposomes modified by a brain-targeting peptide RDP. In addition, intracranial glioma mice model was prepared by transplantation of U251MG cells into the mice striatum, and then the liposomes were intravenously administered into the glioma-bearing mice to evaluate the anti-glioma activity. Results: RDP modified liposomes (RCL) could enter the brain and glioma region, and were internalized by the glioma cells perhaps through acetylcholine receptor-mediated endocytosis pathway. Furthermore, the RCL prolonged the survival time of the glioma-bearing mice from 23 to 33 days, and the inhibition mechanism of the RCL on glioma cell was partly due to cell cycle arrest at the S phase and induction of cell apoptosis. Conclusion: This study would provide a potential approach for targeted delivery of drug-loaded liposomes for glioma treatment. PMID- 29588585 TI - Recent developments in solid lipid nanoparticle and surface-modified solid lipid nanoparticle delivery systems for oral delivery of phyto-bioactive compounds in various chronic diseases. AB - Solid lipid nanoparticle (SLN) delivery systems have a wide applicability in the delivery of phyto-bioactive compounds to treat various chronic diseases, including diabetes, cancer, obesity and neurodegenerative diseases. The multiple benefits of SLN delivery include improved stability, smaller particle size, leaching prevention and enhanced lymphatic uptake of the bioactive compounds through oral delivery. However, the burst release makes the SLN delivery systems inadequate for the oral delivery of various phyto-bioactive compounds that can treat such chronic diseases. Recently, the surface-modified SLN (SMSLN) was observed to overcome this limitation for oral delivery of phyto-bioactive compounds, and there is growing evidence of an enhanced uptake of curcumin delivered orally via SMSLNs in the brain. This review focuses on different SLN and SMSLN systems that are useful for oral delivery of phyto-bioactive compounds to treat various chronic diseases. PMID- 29588588 TI - Tri-block polymer with interfacial layer formation ability and its use in maintaining supersaturated drug solution after dissolution of solid dispersions. AB - Background: Maintaining a supersaturated drug solution after the dissolution of the solid dispersions of water insoluble drugs continues to be a great challenge and is important to the oral bioavailability enhancement of hardly soluble drugs. Methods: Nimodipine solid dispersions were prepared by hot-melt extrusion and a special tri-block polymer was employed as a co-carrier. The solid dispersions were characterized by modulated differential scanning calorimetry, transmission electron microscopy, hydrogen-nuclear magnetic resonance and so on. Results: The tri-block polymer was able to inhibit the formation of drug crystals after dissolution of the solid dispersions. Due to the unique interfacial layer formation ability of the tri-block polymer, a special drug loading micelle which encapsulated the compound and the hydrophobic fragments of the copolymers appeared in the release media. The tri-block polymer was composed of a hydrophilic part forming the shell of micelles, a hydrophobic part shaping the core of micelles, and a special intermediate hydrophilicity part constructing the interfacial layer of micelles. Conclusion: The tri-block polymer was not only able to stabilize the supersaturated drug solution of solid dispersions to enhance the oral bioavailability of hardly soluble drugs, but is also a potential candidate to construct micelles for systemic administration, due to the good compatibility and organic solvents free micelle formation procedure. PMID- 29588589 TI - Hepatocellular carcinoma-targeted effect of configurations and groups of glycyrrhetinic acid by evaluation of its derivative-modified liposomes. AB - Background: There are abundant glycyrrhetinic acid (GA) receptors on the cellular membrane of hepatocytes and hepatocellular carcinoma (HCC) cells. The receptor binding effect might be related to the structure of the guiding molecule. GA exists in two stereoisomers with C3-hydroxyl and C11-carbonyl active groups. Purpose: The objective of this study was to investigate the relationship between the HCC-targeted effect and the configurations and groups of GA. Methods and results: Different GA derivatives (18beta-GA, 18alpha-GA, 3-acetyl-18beta-GA [3 Ace-GA] and 11-deoxy-18beta-GA [11-Deo-GA]) were used to investigate the targeting effect of GA's configurations and groups on HCC cells. The EC50 values of competition to binding sites and the ratio of specific binding in HepG2 cells showed that 18beta-GA and 3-Ace-GA demonstrated significant competitive effect with fluorescein isothiocyanate (FITC)-labeled GA. Then, the GA derivatives were distearoyl-phosphatidylethanolamine (DSPE)-PEGylated. 18beta-GA-, 18alpha-GA-, 3 Ace-GA-and 11-Deo-GA-modified liposomes were prepared and characterized by size, zeta potential, encapsulation efficiency, loading capacity, leakage and membrane stability. Evaluation on the cellular location in vitro and tumor targeting in vivo was carried out. Compared to common long-circulation liposome (PEG-Lip), more 18beta-GA- and 3-Ace-GA-modified liposomes aggregated around HepG2 cells in vitro in short time and transferred into HCC tumors in vivo for a longer time. Conclusion: The beta-configuration hydrogen atom on C18 position of GA played the most important role on the targeting effect. C11-carbonyl and C3-hydroxy groups of GA have certain and little influence on targeting action to HCC, respectively. In general, GA might be a promising targeting molecule for the research on liver diseases and hepatoma therapy. PMID- 29588592 TI - Continuous performance task in ADHD: Is reaction time variability a key measure? AB - Objective: To compare the use of the Continuous Performance Task (CPT) reaction time variability (intraindividual variability or standard deviation of reaction time), as a measure of vigilance in attention-deficit hyperactivity disorder (ADHD), and stimulant medication response, utilizing a simple CPT X-task vs an A X-task. Method: Comparative analyses of two separate X-task vs A-X-task data sets, and subgroup analyses of performance on and off medication were conducted. Results: The CPT X-task reaction time variability had a direct relationship to ADHD clinician severity ratings, unlike the CPT A-X-task. Variability in X-task performance was reduced by medication compared with the children's unmedicated performance, but this effect did not reach significance. When the coefficient of variation was applied, severity measures and medication response were significant for the X-task, but not for the A-X-task. Conclusion: The CPT-X-task is a useful clinical screening test for ADHD and medication response. In particular, reaction time variability is related to default mode interference. The A-X-task is less useful in this regard. PMID- 29588591 TI - Immobilization of a carbon nanomaterial-based localized drug-release system using a bispecific material-binding peptide. AB - Introduction: Inorganic materials are widely used in medical devices, such as artificial hearts, vessels, and joints, in stents, and as nanocarriers for drug delivery systems. Carbon nanomaterials are of particular interest due to their biological inertness and their capability to accommodate molecules. Several attempts have been proposed, in which carbon nanomaterials are used as nanocarriers for the systemic delivery of drugs. Materials and methods: We developed a drug-delivery system in which oxidized single-walled carbon nanohorns (oxSWNHs) were immobilized on a titanium (Ti) surface using material-binding peptides to enable localized drug delivery. For this purpose, we utilized a bispecific peptidic aptamer comprising a core sequence of a Ti-binding peptide and a SWNH-binding peptide to immobilize oxSWNHs on Ti. Results: Scanning electron microscopy was used to confirm the presence of oxSWNHs adsorbed onto the Ti surface, and a quartz crystal microbalance was used to evaluate the binding process during oxSWNH adsorption. The oxSWNHs-ornamented Ti substrate was nontoxic to cells and released biologically active dexamethasone over a sustained period. Conclusion: This oxSWNHs-immobilized system can be used to modify the surface of Ti in implants and be loaded with drugs that stimulate osteogenesis and bone regeneration. PMID- 29588590 TI - Polymer nanofiber-based microchips for EGFR mutation analysis of circulating tumor cells in lung adenocarcinoma. AB - Background: Circulating tumor cells (CTCs) detection, an approach considered to be "liquid biopsy", is a potential alternative method in clinical use for early diagnosis of solid tumor progression. Methods: In this study, we developed a poly (lactic-co-glycolic acid) (PLGA) - nanofiber (PN)-NanoVelcro chip as an efficient device for simple and rapid capture of CTCs from peripheral blood. We evaluated the device performance by assessing the capture efficiency and purity. Single CTC was isolated via laser microdissection system for subsequent genetic analysis, with an aim to find the concordance of epidermal growth factor receptor (EGFR) mutations between tumor tissue and CTCs. Results: PN-NanoVelcro chip exhibits great performance in capture efficiency and high purity. The genetic analysis results showed that most EGFR mutation in tumor tissue could also be detected in CTCs. Conclusion: Compared to computed tomography image results, CTC detection can be implemented throughout the course of diseases and provides an accurate and earlier diagnosis of tumor progression, which make it possible for patients to acquire suitable and timely treatment. PMID- 29588593 TI - Beneficial effects of trimetazidine on expression of serotonin and serotonin transporter in rats with myocardial infarction and depression. AB - Background: Trimetazidine is an anti-ischemic drug that can inhibit platelet aggregation and regulate serotonin (5-hydroxytryptamine [5-HT]) release. The purpose of this study was to investigate the therapeutic effects of trimetazidine on 5-HT and serotonin transporter (SERT) expression in experimentally induced myocardial infarction (MI), depression, and MI + depression. Materials and methods: Eighty Sprague Dawley (SD) rats were randomly divided into a trimetazidine group and a saline group of 40 rats each. The trimetazidine group was given trimetazidine pretreatment for 4 weeks, while the saline group received saline for 4 weeks. Both groups were then subdivided into four subgroups (n=10), which were each subjected to a unique disease condition: sham surgery, MI, depression, or MI + depression. All rats were sacrificed 3 days thereafter, and serum and platelet levels of 5-HT and SERT were assessed. In addition, we experimented with trimetazidine posttreatment. Twenty SD rats underwent MI surgery, and were then randomly divided into a treatment and a saline group (n=10 each). For 4 weeks post-surgery, the trimetazidine group was given trimetazidine, while the saline group received saline. Serum and platelet levels of 5-HT and SERT were assessed. Results: Pretreatment with trimetazidine: in the nontreatment saline group, MI, depression, and MI + depression showed significant declines (P<0.05) in both serum and platelet 5-HT levels compared to sham. Trimetazidine treatment significantly increased serum and platelet 5-HT levels in the MI, depression, and MI + depression (P<0.05) subgroups compared to their counterparts in the saline group. Results for SERT were heterogeneous between serum and platelets. Trimetazidine treatment significantly decreased serum levels of SERT in the sham surgery subgroup (P<0.05), while significantly increasing levels in depression rats, compared to control (P<0.05). In platelets, trimetazidine significantly decreased SERT in sham surgery, MI, depression, and MI + depression rats, compared to control (P<0.05). This contrast suggests that trimetazidine has opposite effects in serum and platelet SERT levels for the three disease models. Post-surgery trimetazidine: increased serum 5-HT (P<0.05) and serum SERT (P<0.05) were observed, compared to control. In platelets, trimetazidine decreased both 5 HT and SERT compared to control, significantly (P<0.05) for 5-HT, but not significantly for SERT (P>0.05). Conclusion: Trimetazidine has a regulatory effect on 5-HT and SERT in the serum and platelets. Because of the downstream effects of this regulation on blood vessel function and myocardial protection, trimetazidine may be a therapeutic or preventive agent in several disease processes, including MI, depression, and the comorbidity between these two diseases. Further investigation, aimed at exploring the clinical potential of trimetazidine, is therefore warranted. PMID- 29588594 TI - The quantification and assessment of depression and anxiety in patients with postoperative gastroparesis syndrome. AB - Background: This study aimed to analyze the stage-situation depression and anxiety as well as independent influential factors in patients with postsurgical gastroparesis syndrome (PGS) and to provide dependent indications for treatment. Patients and methods: The self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were used to test the depression and anxiety of 53 patients with PGS, who were treated in the Department of Gastroenterological Surgery of Gansu Provincial Hospital from January 2012 to October 2016. A comparison between the SDS or SAS scores of patients with PGS and without PGS was undertaken; then, we retrospectively analyzed the factors influencing depression and anxiety in PGS patients. Results: The patients with PGS' mean scores of depression and anxiety were 49.92+/-11.37 and 50.91+/-6.57, respectively, which were higher than that of patients without PGS in the Chinese population (P<0.05). The results of multivariate logistic regression analysis indicated that the independent influential factors of depression and anxiety in patients with PGS included course of disease, pancreatic juice leakage, preoperative outflow tract obstruction, postoperative abdominal infection, and anastomotic complication (P<0.05). Patients with a disease course longer than 30 days; with pancreatic juice leakage; and who suffered from preoperative outflow tract obstruction, postoperative abdominal infection, and anastomotic complication had higher ratios of depression and anxiety. Conclusion: Depression and anxiety are clearly evident in patients with PGS, and we should pay attention to this phenomenon and provide appropriate treatment. PMID- 29588595 TI - The impact of a combined intervention program: an educational and clinical pharmacist's intervention to improve prescribing pattern in hospitalized geriatric patients at King Abdulaziz Medical City in Riyadh, Saudi Arabia. AB - Background: There is a difference between evidence-based guidelines for geriatric patients and clinical practice of physicians. Prescribing potentially inappropriate medications (PIMs) can be attributed to the fact that many physicians are not aware of PIMs usage. Aim: The aim of this study was to assess the effectiveness of a combined intervention program comprising an educational and clinical pharmacist intervention to reduce the incidence of PIMs among hospitalized geriatric patients. Methods: This was a prospective pre-test versus post-test design study. The screening tool of older persons' prescriptions, 2nd version, and 2015 American Geriatric Society Beers' criteria were used to assess the appropriateness of medications prescribed for geriatric inpatients. The study was carried out in the medical wards of the Department of Medicine at King Abdulaziz Medical City in Riyadh, Saudi Arabia. Results: Four hundred geriatric patients were enrolled in the study: 200 in a pre-intervention group (control) and 200 in the intervention group. After the combined intervention, the incidence rate of PIMs decreased significantly from 61% to 29.5% (p<0.001). Out of 317 recommendations given by the clinical pharmacist, the physicians accepted a total of 196 (61.83%) recommendations. The most common PIMs to avoid regardless of diagnosis of geriatric patients before interventions were first-generation antihistamines (46%), sliding scale insulin (18.5%), antipsychotics (6.5%), benzodiazepines (9.5%), and antiarrhythmic drugs (15%). Conclusion: Using a combined intervention program that comprises an educational intervention of updated evidence-based guidelines and clinical pharmacist intervention would add a significant value to improve prescribing patterns in hospitalized geriatric patients. PMID- 29588596 TI - Patients with heart failure and their partners with chronic illness: interdependence in multiple dimensions of time. AB - Background: Informal caregivers play a vital role in supporting patients with heart failure (HF). However, when both the HF patient and their long-term partner suffer from chronic illness, they may equally suffer from diminished quality of life and poor health outcomes. With the focus on this specific couple group as a dimension of the HF health care team, we explored this neglected component of supportive care. Materials and methods: From a large-scale Canadian multisite study, we analyzed the interview data of 13 HF patient-partner couples (26 participants). The sample consisted of patients with advanced HF and their long term, live-in partners who also suffer from chronic illness. Results: The analysis highlighted the profound enmeshment of the couples. The couples' interdependence was exemplified in the ways they synchronized their experience in shared dimensions of time and adapted their day-to-day routines to accommodate each other's changing health status. Particularly significant was when both individuals were too ill to perform caregiving tasks, which resulted in the couples being in a highly fragile state. Conclusion: We conclude that the salience of this couple group's oscillating health needs and their severe vulnerabilities need to be appreciated when designing and delivering HF team based care. PMID- 29588597 TI - Peripheral inflammation/immune indicators of chemosensitivity and prognosis in breast cancer patients treated with neoadjuvant chemotherapy. AB - Introduction: Neoadjuvant chemotherapy (NAC) has become a standard treatment for locally advanced breast cancer. The present study was designed to investigate the predictive value of different peripheral inflammation/immune biomarker responses to NAC and prognosis in breast cancer patients. Materials and methods: A total of 180 breast cancer patients treated with NAC in the First Affiliated Hospital with Nanjing Medical University between January 2008 and March 2015 were enrolled in the study. The associations between inflammation/immune indicators and pathological complete response (pCR) were determined, and the prognostic value of inflammation/immune indicators was also evaluated. Results: In the univariate analysis, patients with a high pretreatment peripheral lymphocyte count (.2.06*109/L) showed a higher pCR rate than those with a low lymphocyte count (23.9% vs 10.4%, P=0.023). The pCR rate of patients with a neutrophil: lymphocyte ratio <=2.15 was significantly higher than that of patients with a high neutrophil: lymphocyte ratio (20% vs 7.8%; P=0.03). However, multivariate analysis revealed that only the high lymphocyte count was predictive for pCR (odds ratio: 4.375, 95% CI: 1.429-13.392, P=0.010). In the survival analysis, patients with a higher neutrophil count (.2.65*109/L) were confirmed to have a shorter disease-free survival (hazard ratio: 4.322, 95% CI: 1.028-18.174, P=0.046), and the high neutrophil count was significantly associated with lymphovascular invasion (P=0.037). Conclusion: We demonstrated that a high level of baseline peripheral lymphocyte count can be a predictor for high efficacy of NAC for breast cancer patients, and low baseline peripheral neutrophil count may contribute to the favorable disease-free survival. PMID- 29588598 TI - Measurement of serum PODXL concentration for detection of pancreatic cancer. AB - Background: The aim of this study was to investigate the use of podocalyxin (PODXL) and secretoglobin family 1D, member 2 (SCGB1D2) expressions in whole blood as diagnostic biomarkers to distinguish between patients with pancreatic cancer and control participants, in comparison with serum cancer antigen 19-9 (CA19-9), which is the current clinical standard. Patients and methods: Flow cytometric analysis was performed to determine the expressions of PODXL and SCGB1D2 on the surface of cultured pancreatic cancer cells. Immunoblotting was performed to determine whether PODXL and SCGB1D2 were detectable in the media of cultured pancreatic cancer cells. A discovery-stage clinical study was performed in a cohort of 23 patients with pancreatic cancer and 51 control individuals without pancreatic disease who had been treated in the Department of Gastroenterology and Hepatology at Kochi Medical School Hospital from April 2014 to January 2016. Serum PODXL and SCGB1D2 levels were measured by enzyme-linked immunosorbent assay (ELISA). Results: PODXL and SCGB1D2 accumulated in the protrusions of cultured pancreatic cancer cells, and they were detectable both on the cell surface and in the cultured media from these cells. The discovery-stage clinical study showed that the area under the receiver-operating characteristic curve (AUC) was 0.96 (95% confidence interval [CI] 0.91-1.000) for PODXL, 0.80 (95% CI 0.67-0.94) for SCGB1D2, and 0.78 (95% CI 0.66-0.90) for CA19-9. The AUC for PODXL was thus significantly higher than that for CA19-9 (P = 0.006). The combination of SCGB1D2 with CA19-9 did not significantly increase the AUC (0.83; 95% CI 0.70-0.96) compared with the AUC for either SCGB1D2 or CA19-9 alone (P = 0.563). Conclusion: PODXL may be a novel, non-invasive diagnostic biomarker for the detection of pancreatic cancer. PMID- 29588599 TI - Modulation of human melanoma cell proliferation and apoptosis by hydatid cyst fluid of Echinococcus granulosus. AB - Objective: The objective of this paper was to assess the effects of hydatid cyst fluid (HCF) of Echinococcus granulosus on melanoma A375 cell proliferation and apoptosis. Methods: A375 cells were classified into five groups by in vitro culture: normal group, control group, 10% HCF group, 20% HCF group and 30% HCF group. Trypan blue staining method was employed to detect the toxicity of HCF. Effects of different concentrations of HCF on melanoma A375 cell proliferation at different time points were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide assay. Flow cytometry and propidium iodide (PI) staining were used to detect cell cycle, and Annexin-V/PI double staining method was used to determine A375 cell apoptotic rate. Western blotting was applied to detect the expression of phosphorylated extracellular regulated protein kinases, proliferating cell nuclear antigen (PCNA), cell-cycle-related proteins (cyclin A, cyclin B1, cyclin D1 and cyclin E) and apoptosis-related proteins (Bcl-2, Bax and caspase-3). Results: HCF with a high concentration was considered as atoxic to A375 cells. HCF promoted A375 cell proliferation, and the effects got stronger with an increase in concentrations but was retarded after reaching a certain range of concentrations. HCF increased phosphorylation level and expression of extracellular regulated protein kinase, as well as PCNA expression. HCF also promoted the transferring progression of A375 cells from the G0/G1 phase to the S phase to increase the cell number in S phase and increased the expression of cyclin A, cyclin D1 and cyclin E. HCF increased the expression of procaspase-3 (the precursor of apoptosis-related protein caspase-3) and antiapoptotic protein Bcl-2, and decreased the expression of proapoptotic factor Bax, thereby inhibiting cell apoptosis. Conclusion: As a result, this study confirmed that HCF promotes proliferation and inhibits apoptosis of melanoma A375 cells. PMID- 29588600 TI - Identification of differentially expressed genes and signaling pathways in ovarian cancer by integrated bioinformatics analysis. AB - Background: The mortality rate associated with ovarian cancer ranks the highest among gynecological malignancies. However, the cause and underlying molecular events of ovarian cancer are not clear. Here, we applied integrated bioinformatics to identify key pathogenic genes involved in ovarian cancer and reveal potential molecular mechanisms. Results: The expression profiles of GDS3592, GSE54388, and GSE66957 were downloaded from the Gene Expression Omnibus (GEO) database, which contained 115 samples, including 85 cases of ovarian cancer samples and 30 cases of normal ovarian samples. The three microarray datasets were integrated to obtain differentially expressed genes (DEGs) and were deeply analyzed by bioinformatics methods. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichments of DEGs were performed by DAVID and KOBAS online analyses, respectively. The protein-protein interaction (PPI) networks of the DEGs were constructed from the STRING database. A total of 190 DEGs were identified in the three GEO datasets, of which 99 genes were upregulated and 91 genes were downregulated. GO analysis showed that the biological functions of DEGs focused primarily on regulating cell proliferation, adhesion, and differentiation and intracellular signal cascades. The main cellular components include cell membranes, exosomes, the cytoskeleton, and the extracellular matrix. The molecular functions include growth factor activity, protein kinase regulation, DNA binding, and oxygen transport activity. KEGG pathway analysis showed that these DEGs were mainly involved in the Wnt signaling pathway, amino acid metabolism, and the tumor signaling pathway. The 17 most closely related genes among DEGs were identified from the PPI network. Conclusion: This study indicates that screening for DEGs and pathways in ovarian cancer using integrated bioinformatics analyses could help us understand the molecular mechanism underlying the development of ovarian cancer, be of clinical significance for the early diagnosis and prevention of ovarian cancer, and provide effective targets for the treatment of ovarian cancer. PMID- 29588602 TI - Upregulated long non-coding RNAs demonstrate promising efficacy for breast cancer detection: a meta-analysis. AB - Purpose: Focusing on the latest literature, dysregulated long non-coding RNAs (lncRNAs) have been extensively explored in breast cancer (BC) research. The purpose of this meta-analysis is to synthesize the evidence on the diagnostic performance of abnormally expressed lncRNAs for BC. Materials and methods: Relevant studies were searched in multiple electronic databases. The Quality Assessment of Diagnosis Accuracy Studies II criteria were applied to assess the quality of included studies. The bivariate meta-analysis model was applied to synthesize the diagnostic parameters using Stata 12.0 software. Publication bias was judged in terms of the Deek's funnel plot asymmetry test. Results: We included 10 eligible studies, which comprised 835 BC patients and 725 paired controls for this meta-analysis. The pooled sensitivity, specificity, diagnostic odds ratio, likelihood ratio positive, likelihood ratio negative, and area under the curve (AUC) of upregulated lncRNA expression signature in confirming BC were 0.79 (95% CI: 0.70-0.85), 0.80 (95% CI: 0.73-0.85), 14.61 (95% CI: 10.91-19.55), 3.90 (95% CI: 3.03-5.02), 0.27 (95% CI: 0.20-0.36), and 0.86, respectively. Stratified analyses yielded a sensitivity of 0.83 (95% CI: 0.80-0.86) for serum based analysis, which was higher than plasma-based analysis, whereas plasma-based analysis revealed a greater specificity of 0.88 (95% CI: 0.85-0.91). Moreover, lncRNA-homeotic genes (HOX) transcript antisense RNA showed a pooled specificity of 0.89 (95% CI: 0.84-0.93) and AUC of 0.86, which were superior to performances by lncRNA-metastasis-associated lung adenocarcinoma transcript-1 and -H19 in diagnosing BC. Notably, the analysis based on cancer subtypes demonstrated that lncRNA expression signature could distinguish triple-negative BC (lacks estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression) from non-triple-negative BC, with an AUC of 0.85. Conclusion: Upregulated lncRNAs reveal an immense potential as novel non-invasive biomarker(s) that could complement BC diagnosis. PMID- 29588601 TI - Midazolam activates caspase, MAPKs and endoplasmic reticulum stress pathways, and inhibits cell cycle and Akt pathway, to induce apoptosis in TM3 mouse Leydig progenitor cells. AB - Background: Midazolam (MDZ) has powerful hypnosis, amnesia, anti-anxiety and anticonvulsant effects. Studies have shown that prenatally developmental toxicity of diazepam can be observed in many organs/tissues. However, it remains elusive in male reproductive system. Materials and methods: TM3 mouse Leydig progenitor cell line was used to determine whether MDZ has any unfavorable effects. Results: Midazolam significantly decreased cell viability in dose- and time-dependent manners in TM3 cells. In flow cytometry analysis, midazolam significantly increased subG1 phase cell numbers, and annexin V/PI double staining assay further confirmed that MDZ induced apoptosis in TM3 cells. Moreover, MDZ significantly induced the expression of caspase-8 and -3 proteins and the phosphorylation of JNK, ERK1/2 and p38. Besides, MDZ didn't activate Akt pathway in TM3 cells. Furthermore, the expressions of p-EIF2alpha, ATF4, ATF3 and CHOP were induced by midazolam, suggesting that midazolam could induce apoptosis through endoplasmic reticulum (ER) stress in TM3 cells. Additionally, the expressions of cyclin A, cyclin B and CDK1 were inhibited by midazolam through the regulation of p53 in TM3 cells, indicating that midazolam could regulate cell cycle to induce apoptosis. Conclusion: Midazolam could activate caspase, MAPKs and ER stress pathways and impede Akt pathway and cell cycle to induce apoptosis in TM3 mouse Leydig progenitor cells. PMID- 29588603 TI - STK39 blockage by RNA interference inhibits the proliferation and induces the apoptosis of renal cell carcinoma. AB - Aim: Renal cell carcinoma (RCC), the most frequent type of primary renal malignancies, has a high mortality rate. Serine/threonine kinase 39 (STK39) is associated with various human diseases, including cancers. The current study aimed to investigate the functions of STK39 in RCC. Materials and methods: STK39 expression levels in RCC and paired normal renal tissue samples were detected by real-time polymerase chain reaction and Western blotting analyses. The biological functions of STK39 were explored in two RCC cell lines with STK39 silence. Results: STK39 expression was significantly increased in RCC tissues than in normal renal tissues. Suppression of STK39 expression in ACHN and 786-0 cells significantly suppressed cell proliferation and induced cell apoptosis. Consistently, the expression of PCNA and Bcl-2 was remarkably increased, while the expression of Bax was significantly in STK39 knockdown cells compared to control cells. Furthermore, gene set enrichment analysis identified STK39 as an important regulator of p53 and p38 signaling pathways. STK39 knockdown increased p53 expression and inhibited p38 phosphorylation. Moreover, ectopic expression of STK39 in ACHN cells resulted in a reduced p53 expression and increased c-Myc and p-p38 expression. Such effects were suppressed by p38 inhibitor (SB203580). Conclusion: STK39 may exert its oncogenic function in RCC through p38 signaling. Our data suggest that STK39 may represent a potential therapeutic target against RCC. PMID- 29588604 TI - Primary mucinous carcinoma of thyroid gland with prominent signet-ring-cell differentiation: a case report and review of the literature. AB - Purpose: This study reports a case of primary mucinous carcinoma of the thyroid gland with signet-ring-cell differentiation, and reviews the literature to evaluate its real incidence and the prognosis of these patients. Patients and methods: A 74-year-old Chinese woman, presenting with a mass in the right lobe of thyroid gland, came to the hospital. Computed tomography revealed a mass in the right lobe of the thyroid gland, accompanied with right neck lymphadenectasis and airway deviation caused by tumor compression. Thyroid imaging suggested a thyroid malignant tumor and suspicious lymph node metastasis. Histologically, the tumor was characterized by the tumor cells arranged in small nests or trabeculae with an abundant extracellular mucoid matrix. The tumor cells formed diffuse invasion among thyroid follicles. In the peripheral regions, prominent signet-ring-cells formed a sheet-like structure and extended into the extrathyroidal fat tissue. The tumor cells were diffusely positive for thyroid transcription factor-1 (TTF 1) and PAX8, while they were focally positive for pan-cytokeratin (AE1/AE3) and weakly expressed thyroglobulin. Results: Based on the histological features and immunohistochemical profile, a diagnosis of primary mucinous carcinoma of the thyroid gland with signet-ring-cell differentiation was rendered. Conclusion: Using a panel of immunohistochemical markers may be helpful for differential diagnosis and for determining whether the tumor is primary or not. PMID- 29588605 TI - A systematic review and meta-analysis on the use of prophylactic topical antibiotics for the prevention of uncomplicated wound infections. AB - Background: The prescription of topical antibiotics for the prevention of infections in uncomplicated wounds is common. However, the efficacy is not well reported. Therefore, the objective of the study was to conduct a systematic review and meta-analysis of the available evidence on prevention of uncomplicated wound infections by prophylactic topical antibiotics. Materials and methods: The search included Pubmed, Google Scholar, SCOPUS, Embase, Cochrane, ClinicalTrials.gov, International Clinical Trials Registry Platform, National Technical Information Service, and the National Guidelines Clearinghouse. Results: We identified eight randomized controlled trials and four quasi randomized trials that met the criteria for the systematic review. Of these trials, 11 studies were pooled for meta-analysis to compare the effects of topical antibiotics versus placebo and 4 studies were pooled for comparison of effects of topical antibiotics versus topical antiseptics on uncomplicated wounds. Fewer wound infections occurred in the topical antibiotic arms compared to placebo (pooled risk ratio: 0.57 [95% CI: 0.37 to 0.86]; p=0.01 and pooled risk difference: -3.1% [95% CI: -5.8% to -0.34%]; p=0.03). Compared to antiseptics, topical antibiotics demonstrated statistically significant relative risk reduction (pooled risk ratio: 0.56 [95% CI: 0.23 to 0.91]; p=0.02), while there was no significant absolute risk reduction (pooled risk difference: -3.7% [95% CI: -7.9% to +0.6%]; p=0.09). Conclusion: Topical antibiotics are effective in reducing wound infections after surgical procedures, but the absolute benefit is small. Given the global emergence of antimicrobial resistance, judicious use of antibiotics is encouraged and use of antiseptics should be considered as a reasonable alternative to topical antibiotics. PMID- 29588606 TI - Cost utility, budget impact, and scenario analysis of racecadotril in addition to oral rehydration for acute diarrhea in children in Malaysia. AB - Objective: To perform cost utility (CU) and budget impact (BI) analyses augmented by scenario analyses of critical model structure components to evaluate racecadotril as adjuvant to oral rehydration solution (ORS) for children under 5 years with acute diarrhea in Malaysia. Methods: A CU model was adapted to evaluate racecadotril plus ORS vs ORS alone for acute diarrhea in children younger than 5 years from a Malaysian public payer's perspective. A bespoke BI analysis was undertaken in addition to detailed scenario analyses with respect to critical model structure components. Results: According to the CU model, the intervention is less costly and more effective than comparator for the base case with a dominant incremental cost-effectiveness ratio of -RM 1,272,833/quality adjusted life year (USD -312,726/quality-adjusted life year) in favor of the intervention. According to the BI analysis (assuming an increase of 5% market share per year for racecadotril+ORS for 5 years), the total cumulative incremental percentage reduction in health care expenditure for diarrhea in children is 0.136578%, resulting in a total potential cumulative cost savings of RM 73,193,603 (USD -17,983,595) over a 5-year period. Results hold true across a range of plausible scenarios focused on critical model components. Conclusion: Adjuvant racecadotril vs ORS alone is potentially cost-effective from a Malaysian public payer perspective subject to the assumptions and limitations of the model. BI analysis shows that this translates into potential cost savings for the Malaysian public health care system. Results hold true at evidence-based base case values and over a range of alternate scenarios. PMID- 29588607 TI - Cost analysis of a growth guidance system compared with traditional and magnetically controlled growing rods for early-onset scoliosis: a US-based integrated health care delivery system perspective. AB - Purpose: Treating early-onset scoliosis (EOS) with traditional growing rods (TGR) is effective but requires periodic surgical lengthening, risking complications. Alternatives include magnetically controlled growing rods (MCGR) that lengthen noninvasively and the growth guidance system (GGS), which obviate the need for active, distractive lengthenings. Previous studies have reported promising clinical effectiveness for GGS; however the direct medical costs of GGS compared to TGR and MCGR have not yet been explored. Methods: To estimate the cost of GGS compared with MCGR and TGR for EOS an economic model was developed from the perspective of a US integrated health care delivery system. Using dual-rod constructs, the model estimated the cumulative costs associated with initial implantation, rod lengthenings (TGR, MCGR), revisions due to device failure, surgical-site infections, device exchange, and final spinal fusion over a 6-year episode of care. Model parameters were from peer-reviewed, published literature. Medicare payments were used as a proxy for provider costs. Costs (2016 US$) were discounted 3% annually. Results: Over a 6-year episode of care, GGS was associated with fewer invasive surgeries per patient than TGR (GGS: 3.4; TGR: 14.4) and lower cumulative costs than MCGR and TGR, saving $25,226 vs TGR. Sensitivity analyses showed that results were sensitive to changes in construct costs, rod breakage rates, months between lengthenings, and TGR lengthening setting of care. Conclusion: Within the model, GGS resulted in fewer invasive surgeries and deep surgical site infections than TGR, and lower cumulative costs per patient than both MCGR and TGR, over a 6-year episode of care. The analysis did not account for family disruption, pain, psychological distress, or compromised health-related quality of life associated with invasive TGR lengthenings, nor for potential patient anxiety surrounding the frequent MCGR lengthenings. Further analyses focusing strictly on current generation technologies should be considered for future research. PMID- 29588608 TI - The relationship between mitotic rate and depth of invasion in biopsies of malignant melanoma. AB - Background: Malignant melanoma of the skin is a potentially lethal neoplasm that generally originates from atypical melanocytes in the dermal-epidermal junction. When the neoplasm penetrates into the dermis, several variables can affect the extent of its spread, among which depth of invasion has the most important prognostic value. Mitotic rate is another prognostic factor that reflects the biological behavior of the neoplasm. Objective: This study was designed to evaluate the probable relationship between the depth of invasion of malignant melanoma and its mitotic rate. Materials and methods: This study was performed on 50 excisional biopsy specimens that had received the diagnosis of malignant melanoma histopathologically. Tumor characteristics including Breslow thickness, Clark level, T-stage, and tumor mitotic rate were recorded. Results: We observed that at higher Clark levels and higher T-stages, and the mean mitotic rate was significantly increased. Moreover, there was a positive and significant correlation between Breslow thickness and mitotic rate. We demonstrated that one unit increase in mitotic rate was correlated with 0.8 mm increase in Breslow thickness of the tumor. Conclusion: In malignant melanoma, mitotic activity may probably indicate the depth of tumor invasion. Therefore, in incisional biopsies where depth of invasion cannot be accurately determined, the mitotic activity may be used to estimate Breslow thickness, which is necessary for planning surgical management. PMID- 29588610 TI - Unmet service needs evaluated by case managers among disabled patients on hemodialysis in Japan. AB - Background: This study aimed to investigate the levels of unmet needs for home and community-based services (HCBS) evaluated by case managers (CMs) among disabled patients on hemodialysis (DPHD) and to examine factors related to unmet needs. Unmet needs for HCBS were defined as situations in which patients do not use or underuse HCBS despite needing them. Candidates for the factors relating to unmet needs for HCBS included three dimensions: predisposing, enabling, and need factors. Methods: Self-administrated questionnaires were collected from 391 CMs of DPHD certified with long-term care insurance. These were introduced by the dialysis facilities that a member of the Japanese Association of Dialysis Physicians belonged to. CMs were asked questions about their management of each individual case. HCBS included home help, visiting nursing, daycare, and short stay. Results: The prevalence of unmet needs for each HCBS ranged from 32% for home help to 48% for short stay. Barriers to service usage in the patients were associated with unmet needs for all four services. The patients with more severe cognitive malfunction were more likely to have unmet needs for visiting nursing and short stay. Heavier burden with caregiving was associated with more likelihood of unmet needs for home help and short stay. Conclusion: CMs need to monitor unmet needs after coordinating HCBS for DPHD and need to encourage HBCS use among patients with impaired cognitive function and caregivers with heavier caregiving burdens. PMID- 29588609 TI - Postoperative pancreatic fistula: a review of traditional and emerging concepts. AB - Postoperative pancreatic fistula (POPF) remains the major cause of morbidity after pancreatic resection, affecting up to 41% of cases. With the recent development of a consensus definition of POPF, there has been a large number of reports examining various risk factors, prediction models, and mitigation strategies for this costly complication. Despite these strategies, the rates of POPF have not significantly diminished. Here, we review the literature and evidence regarding both traditional and emerging concepts in POPF prediction, prevention, and management. In particular, we review the evidence for the association between postoperative pancreatitis and POPF, and present a novel proposed mechanism for the development of POPF. PMID- 29588611 TI - The utility of pharmacogenetic testing to support the treatment of bipolar disorder. AB - Background: Bipolar disorder (BD) is a frequent cause of disability, health care costs, and risk of suicide. Pharmacogenetic tests (PGTs) could help clinicians to identify those patients predisposed to the occurrence of adverse events (AEs) improving the understanding of the correlation between genetic variants and drug response. Materials and methods: The study evaluated 30 patients affected by BD type I or II (according to Diagnostic and Statistical Manual of Mental Disorders, version 5) who underwent the PGT Neurofarmagen(r) (AB-BIOTICS SA, Barcelona, Spain) between March 2016 and March 2017. The primary aim of this study was to identify if the treatment prescribed by the psychiatrists was consistent with the treatment suggested by the PGT at T0 (corresponding to the test report communication). As a secondary aim, we wanted to assess if clinicians had changed the treatment (in case of discordance) at T1 (3-month follow-up visit) according to the results of the PGT. Results: At T0, only 4 patients (13%) had an optimal therapy in line with the PGT suggestions. At 3-month follow-up, 13 patients (40%) had received a change of therapy consistent to the test, showing a significant statistical improvement in the Clinical Global Impression item Severity (CGI-S) score over time compared to those not having changes consistent with the test. Regarding AEs, at baseline 9 out of 10 (90%) of the patients who received a therapy modification according to the test presented AEs, and a significant within-group reduction was observed after 3 months (p = 0.031). Conclusion: Despite the small sample size, the study shows promising data about the usefulness of PGT to support clinicians in reaching a more effective and tolerated treatment in the routine approach of BD. PMID- 29588612 TI - Radiation-induced neuropathic pain successfully treated with systemic lidocaine administration. AB - Radiation-induced neuropathic pain is a rare but devastating complication following cancer treatment. It is often progressive, refractory to conservative treatment, and sometimes irreversible. The exact mechanism of radiation-induced neuropathic pain is unknown, but it is associated with perineural fibrosis, atrophy, and ischemia. Systemic administration of local anesthetics is known to be effective for various acute and chronic painful diseases, such as neuropathic pain, as well as inflammatory and nociceptive pains. We report a patient with generalized radiation-induced neuropathic pain successfully treated with systemic lidocaine administration. PMID- 29588613 TI - Buprenorphine and pain treatment in pediatric patients: an update. AB - Introduction: The usual management of moderate to severe pain is based on the use of opioids. Buprenorphine (BPN) is an opioid with an analgesic potency 50 times greater than that of morphine. It is widely used in various pain models and has demonstrated efficacy and safety in adult patients; however, there are insufficient clinical trials in pediatric populations. Purpose: The aim of this study was to perform an updated meta-analysis on the implementation of BPN in the treatment of pain in the pediatric population. Methods: A bibliographic search was carried out in different biomedical databases to identify scientific papers and clinical trials with evidence of BPN use in children and adolescents. Results: A total of 89 articles were found, of which 66 were selected. Analysis of these items revealed additional sources, and the final review included a total of 112 publications. Conclusion: Few studies were found regarding the efficacy and safety of BPN use in children. In recent years, the use of this drug in the pediatric population has become widespread, so it is imperative to perform clinical trials and pharmacological and pharmacovigilance studies, which will allow researchers to develop dosage schemes based on the evidence and minimize the risk of adverse effects. PMID- 29588614 TI - Practice and bias in intraoperative pain management: results of a cross-sectional patient study and a survey of anesthesiologists. AB - Background: Perioperative pain carries a considerable risk of becoming persistent; hence aggressive preventive approaches are advocated. Persistently high prevalence of postoperative pain, however, suggests anesthesiologists underuse these strategies. A prospective cross-sectional study of patients in the postanesthetic care unit (PACU) and a survey of anesthesiologists were thus conducted to evaluate practice and uncover bias in intraoperative pain management. Methods: Notes of PACU patients were reviewed and information regarding surgical context, comorbidities, and analgesic administration was retrieved. Variables were analyzed for their predictive properties on pain and intraoperative analgesic management. Furthermore, clinical dose-effect estimates for intraoperative morphine were determined. Finally, anesthesiologists completed a questionnaire comprising statements regarding pain relating to surgical context and morphine administration. Results: Data of 200 patients and 55 anesthesiologists were analyzed. Prevalence of pain in PACU was 28% and was predicted by local anesthetic (LA) and low-dose morphine administration. Additionally, when LA was used, little coanalgesics were employed. These results suggest a restrained approach by anesthesiologists toward intraoperative pain management. It is supported by their reluctance to administer more than 10 mg morphine, despite these individuals regarding this practice as insufficient. The hesitancy toward morphine also transpired in the dose-effect estimates with the average applied dose operating on an ED63 instead of an ED95 level. Conclusion: This study confirmed a high prevalence of pain in PACU. It also indicated conservative intraoperative analgesic administration by anesthesiologists. The modest morphine usage and overreliance on LA application, which are not supported by published evidence, additionally suggest bias in current intraoperative pain management. PMID- 29588616 TI - Optimal management of orthodontic pain. AB - Pain is an undesirable side effect of orthodontic tooth movement, which causes many patients to give up orthodontic treatment or avoid it altogether. The aim of this study was to investigate, through an analysis of the scientific literature, the best method for managing orthodontic pain. The methodological aspects involved careful definition of keywords and diligent search in databases of scientific articles published in the English language, without any restriction of publication date. We recovered 1281 articles. After the filtering and classification of these articles, 56 randomized clinical trials were selected. Of these, 19 evaluated the effects of different types of drugs for the control of orthodontic pain, 16 evaluated the effects of low-level laser therapy on orthodontic pain, and 21 evaluated other methods of pain control. Drugs reported as effective in orthodontic pain control included ibuprofen, paracetamol, naproxen sodium, aspirin, etoricoxib, meloxicam, piroxicam, and tenoxicam. Most studies report favorable outcomes in terms of alleviation of orthodontic pain with the use of low-level laser therapy. Nevertheless, we noticed that there is no consensus, both for the drug and for laser therapy, on the doses and clinical protocols most appropriate for orthodontic pain management. Alternative methods for orthodontic pain control can also broaden the clinician's range of options in the search for better patient care.

AB - Purpose: Current evidence on the care-delivering process and the intensity of treatment at the end-of-life of cancer patients is limited and remains unclear. Our objective was to examine the care-delivering processes in health care during the last months of life with real-life data of Swiss cancer patients. Patients and methods: The study population consisted of adult decedents in 2014 who were insured at Helsana Group. Data on the final cause of death were provided additionally by the Swiss Federal Statistical Office. Of the 10,275 decedents, 2,710 (26.4%) died of cancer. Intensity of treatment and health care utilization (including transitions) at their end-of-life were examined. Intensity measures included the following: last dose of chemotherapy within 14 days of death, a new chemotherapy regimen starting <30 days before death, more than one hospital admission or spending >14 days in hospital in the last month, death in an acute care hospital, more than one emergency visit and >=1 intensive care unit admission in the last month of life. Results: In the last 6 months of life, 89.5% of cancer patients had >=1 transition, with 87.2% being hospitalized. Within 30 days before death, 64.2% of the decedents had >=1 intensive treatment, whereby 8.9% started a new chemotherapy. In the multinomial logistic regression model, older age, higher density of nursing home beds and home care nurses were associated with a decrease, while living in the Italian- or French-speaking part of Switzerland was associated with an increase in intensive care. Conclusion: Swiss cancer patients insured by Helsana Group experience a considerable number of transitions and intensive treatments at the end-of-life, whereby treatment intensity declines with increasing age. Among others, increased home care nursing might be helpful to reduce unwarranted treatments and transitions, therefore leading to better care at the end-of-life. PMID- 29588618 TI - Immunocompetence and mechanism of the DRibble-DCs vaccine for oral squamous cell carcinoma. AB - Background: Due to the high-quality immunogenicity of tumor-derived autophagosomes (DRibbles), we aimed to explore the antitumor ability and mechanism of DRibble-loaded dendritic cells (DRibble-DCs). Materials and methods: DRibbles extracted from the oral squamous cell carcinoma cell line SCC7 express specific LC3-II and ubiquitination marker. Immunization of mice with the DRibble DCs vaccine led to the proliferation and differentiation of CD3+CD4+IFN-gamma+ and CD3+CD8+IFN-gamma+ T cells. The expression of proteins in endoplasmic reticulum stress (ERS) pathways was determined by Western blotting. Additionally, the functional properties of the DRibble-DCs were examined in mice, and regulatory T cells were measured by flow cytometry. Results: Excellent biocompatibility was observed in vitro when DCs were loaded with DRibbles. T cells of lymph nodes and spleens from mice immunized with DRibble-DCs had cytotoxic effects on SCC7 cells. DCs homeostasis and ERS-related proteins were affected by DRibbles. Moreover, the DRibble-DCs vaccine achieved significantly better antitumor efficacy than DRibbles and tumor cell lysate-loaded DCs. Conclusion: The results validated the antitumor immune responses to the DRibble DCs vaccine in vivo and in vitro. The ERS pathway can be affected by DRibbles. PMID- 29588615 TI - Management of pain in patients with temporomandibular disorder (TMD): challenges and solutions. AB - Thanks to advances in neuroscience, biopsychosocial models for diagnostics and treatment (including physical, psychological, and pharmacological therapies) currently have more clinical support and scientific growth. At present, a conservative treatment approach prevails over surgery, given it is less aggressive and usually results in satisfactory clinical outcomes in mild-moderate temporomandibular disorder (TMD). The aim of this review is to evaluate the recent evidence, identify challenges, and propose solutions from a clinical point of view for patients with craniofacial pain and TMD. The treatment we propose is structured in a multi-modal approach based on a biobehavioral approach that includes medical, physiotherapeutic, psychological, and dental treatments. We also propose a new biobehavioral model regarding pain perception and motor behavior for the diagnosis and treatment of patients with painful TMD. PMID- 29588619 TI - Primary clear cell carcinoma of the thymus and literature comparison of features. AB - Clear cell carcinoma arising from the thymus is considered exceedingly rare. It shows aggressive clinical behavior and demonstrates frequent local recurrences as well as widespread metastasis. The detailed clinical data of one patient with thymic clear cell carcinoma were compiled, and a review of relevant reported studies was performed. We summarized the clinical characteristics, pathological diagnosis of the patient and other reported cases. The analysis showed that older male patients were more likely to suffer, and the manifestations included chest pain and dyspnea. Some patients are asymptomatic, with the tumor being discovered during physical examination. Histologically, thymic clear cell carcinoma is composed of lobulated structures arranged in hyperchromatic fibrous stroma; the tumor cells are uniform with obvious nucleoli and clear cytoplasm. To establish the correct diagnosis, consideration and exclusion of metastasis and other original tumors in the differential diagnosis by immunohistochemistry, clinical and radiologic correlation is important. PMID- 29588620 TI - In-room ultrasound fusion combined with fully compatible 3D-printed holding arm - rethinking interventional MRI. AB - There is no real need to discuss the potential advantages - mainly the excellent soft tissue contrast, nonionizing radiation, flow, and molecular information - of magnetic resonance imaging (MRI) as an intraoperative diagnosis and therapy system particularly for neurological applications and oncological therapies. Difficult patient access in conventional horizontal-field superconductive magnets, very high investment and operational expenses, and the need for special nonferromagnetic therapy tools have however prevented the widespread use of MRI as imaging and guidance tool for therapy purposes. The interventional use of MRI systems follows for the last 20+ years the strategy to use standard diagnostic systems and add more or less complicated and expensive components (eg, MRI compatible robotic systems, specially shielded in-room monitors, dedicated tools and devices made from low-susceptibility materials, etc) to overcome the difficulties in the therapy process. We are proposing to rethink that approach using an in-room portable ultrasound (US) system that can be safely operated till 1 m away from the opening of a 3T imaging system. The live US images can be tracked using an optical inside-out approach adding a camera to the US probe in combination with optical reference markers to allow direct fusion with the MRI images inside the MRI suite. This leads to a comfortable US-guided intervention and excellent patient access directly on the MRI patient bed. This was combined with an entirely mechanical MRI-compatible 7 degrees of freedom holding arm concept, which shows that this test environment is a different way to create a cost-efficient and effective setup that combines the advantages of MRI and US by largely avoiding the drawbacks of current interventional MRI concepts. PMID- 29588621 TI - Investigating the effects of cervical collar design and fit on the biomechanical and biomarker reaction at the skin. AB - Background: Research has shown that up to 33% of pressure ulcers (PUs) acquired in hospitals result from the application of a medical device. Cervical collars (C collars) have been implicated in causing PUs, due to the mechanical force they apply to the skin. In order to improve our understanding of collar-related PUs, the present study aimed to assess the biomechanical, biochemical, and microclimate effects of C-collar design and fitting tension. Methods: A cohort of 15 healthy volunteers was fit with two different C-collars according to the manufacturer guidelines. Two further collar tensions were also defined as loose and tight for each device. Each collar condition was applied for 15 minutes, with a 10 minute refractory period. Measurements at the device-skin interface included interface pressures, inflammatory biomarkers, microclimate, range of cervical motion, and comfort scores. Results: The interface pressures at each tissue site increased monotonically with greater collar tension (p<0.01), irrespective of collar design. Biomarker analysis revealed that inflammatory cytokines (IL-1a) were elevated during collar application, with the highest increase during the tight fit condition, representing over a fourfold increase from unloaded conditions. Regardless of collar tension or type, there was an increase in temperature 1.5 degrees C +/-0.8 degrees C compared to baseline values. Range of motion significantly decreased with greater strap tension (p<0.05), with an associated increase in discomfort. Conclusion: The present findings revealed that increasing C-collar tensions caused elevated contact pressures at the device-skin interface, with a corresponding inflammatory response at the skin. These peak contact pressures were highest at the occiput, corresponding with reported PU locations. Devices should be designed to uniformly distribute pressures, and appropriate guidance is needed for their application. PMID- 29588622 TI - Physical activity after total joint arthroplasty: a narrative review. AB - Background: Total joint arthroplasty (TJA) is a common procedure to treat individuals with hip and knee osteoarthritis. While TJAs are successful in decreasing pain and improving quality of life, it is unclear whether individuals who undergo TJA become more physically active after surgery. It is possible that TJA, by itself, is not sufficient to affect the behavior of patients toward physical activity (PA) participation. To increase PA participation, individuals with TJA may need to be exposed to exercise/behavioral interventions specifically aimed to promote PA (ie, in addition to the surgery). Objectives: This narrative review aimed to assess the evidence on 1) whether TJAs change PA participation from pre- to postsurgery and 2) whether exercise/behavioral interventions delivered before or after TJA help to promote PA in these patients. Results: For aim 1, the studies that assessed PA from pre- to post-TJA reported that PA does not change in the first 3 months postsurgery. The results of follow-ups longer than 3 months but shorter than 12 months are contradictory, and the results of follow-ups longer than 12 months provide weak evidence of increased PA. Assessment of changes in PA due to TJA is challenged by the wide variability in demographics, methods used to assess PA, and different pathways of care used across studies. The results for aim 2 were limited by a scarcity of studies that used exercise/behavioral interventions to promote PA. Conclusion: TJA relieves joint pain and offers a unique opportunity for patients to become more physically active. However, the current evidence is limited and unable to offer definitive results of whether TJA is effective to change PA from pre- to postsurgery. Future large studies in representative samples of patients with TJA are needed to adequately answer this question. PMID- 29588623 TI - National Institutes of Health Toolbox Emotion Battery for English- and Spanish speaking adults: normative data and factor-based summary scores. AB - Background: The National Institutes of Health Toolbox Emotion Battery (NIHTB-EB) is a "common currency", computerized assessment developed to measure the full spectrum of emotional health. Though comprehensive, the NIHTB-EB's 17 scales may be unwieldy for users aiming to capture more global indices of emotional functioning. Methods: NIHTB-EB was administered to 1,036 English-speaking and 408 Spanish-speaking adults as a part of the NIH Toolbox norming project. We examined the factor structure of the NIHTB-EB in English- and Spanish-speaking adults and developed factor analysis-based summary scores. Census-weighted norms were presented for English speakers, and sample-weighted norms were presented for Spanish speakers. Results: Exploratory factor analysis for both English- and Spanish-speaking cohorts resulted in the same 3-factor solution: 1) negative affect, 2) social satisfaction, and 3) psychological well-being. Confirmatory factor analysis supported similar factor structures for English- and Spanish speaking cohorts. Model fit indices fell within the acceptable/good range, and our final solution was optimal compared to other solutions. Conclusion: Summary scores based upon the normative samples appear to be psychometrically supported and should be applied to clinical samples to further validate the factor structures and investigate rates of problematic emotions in medical and psychiatric populations. PMID- 29588624 TI - Stereotactic body radiation therapy (SBRT) in the management of non-small-cell lung cancer: Clinical impact and patient perspectives. AB - Stereotactic body radiation therapy (SBRT) has emerged as a new technology in radiotherapy delivery, allowing for potentially curative treatment in many patients previously felt not to be candidates for radical surgical resection of stage I non-small-cell lung cancer (NSCLC). Several studies have demonstrated very high local control rates using SBRT, and more recent data have suggested overall survival may approach that of surgery in operable patients. However, SBRT is not without unique toxicities, and the balance of toxicity, and effect on patient-reported quality of life need to be considered with respect to oncologic outcomes. We therefore aim to review SBRT in the context of important patient related factors, including quality of life in several domains (and in comparison to other therapies such as conventional radiation, surgery, or no treatment). We will also describe scenarios in which SBRT may be reasonably offered (i.e. elderly patients and those with severe COPD), and where it may need to be approached with some caution due to increased risks of toxicity (i.e. tumor location, patients with interstitial lung disease). In total, we hope to characterize the physical, emotional, and functional consequences of SBRT, in relation to other management strategies, in order to aid the clinician in deciding whether SBRT is the optimal treatment choice for each patient with early stage NSCLC. PMID- 29588625 TI - Duchenne and Becker muscular dystrophy in adolescents: current perspectives. AB - Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are life limiting and progressive neuromuscular conditions with significant comorbidities, many of which manifest during adolescence. BMD is a milder presentation of the condition and much less prevalent than DMD, making it less represented in the literature, or more severely affected individuals with BMD may be subsumed into the DMD population using clinical cutoffs. Numerous consensus documents have been published on the clinical management of DMD, the most recent of which was released in 2010. The advent of these clinical management consensus papers, particularly respiratory care, has significantly increased the life span for these individuals, and the adolescent years are now a point of transition into adult lives, rather than a period of end of life. This review outlines the literature on DMD and BMD during adolescence, focusing on clinical presentation during adolescence, impact of living with a chronic illness on adolescents, and the effect that adolescents have on their chronic illness. In addition, we describe the role that palliative-care specialists could have in improving outcomes for these individuals. The increasing proportion of individuals with DMD and BMD living into adulthood underscores the need for more research into interventions and intracacies of adolescence that can improve the social aspects of their lives. PMID- 29588626 TI - Epistructured catechins, EGCG and EC facilitate apoptosis induction through targeting de novo lipogenesis pathway in HepG2 cells. AB - Background: Abnormally high expression of the mammalian de novo lipogenesis (DNL) pathway in various cancer cells promotes cell over-proliferation and resistance to apoptosis. Inhibition of key enzymes in the DNL pathway, namely, ATP citrate lyase, acetyl-CoA carboxylase, and fatty acid synthase (FASN) can increase apoptosis without cytotoxicity to non-cancerous cells, leading to the search for and presentation of novel selective and powerful targets for cancer therapy. Previous studies reported that epistructured catechins, epigallocatechin gallate (EGCG) and epicatechin (EC) exhibit different mechanisms regarding a strong inducer of apoptosis in various cancer cell lines. Thus, the current study investigated the growth inhibitory effect of EGCG and EC, on the enzyme expression and activity of the DNL pathway, which leads to the prominent activity of carnitine palmitoyl transferase-1 (CPT-1) mediating apoptosis in HepG2 cells. Methods: The cytotoxicity on HepG2 cells of EGCG and EC was determined by MTT assay. Cell death caused by apoptosis, the dissipation of mitochondrial membrane potential (MMP), and cell cycle arrest were then detected by flow cytometry. We further investigated the decrease of fatty acid levels associated with DNL retardation, followed by evaluation of DNL protein expression. Then, the negative inhibitory effect of depleted fatty acid synthesis on malonyl-CoA synthesis followed by regulating of CPT-1 activity was investigated. Thereafter, we inspected the enhanced reactive oxygen species (ROS) generation, which is recognized as one of the causes of apoptosis in HepG2 cells. Results: We found that EGCG and EC decreased cancer cell viability by increasing apoptosis as well as causing cell cycle arrest in HepG2 cells. Apoptosis was associated with MMP dissipation. Herein, EGCG and EC inhibited the expression of FASN enzymes contributing to decreasing fatty acid levels. Notably, this decrease consequently showed a suppressing effect on the CPT-1 activity. We suggest that epistructured catechin-induced apoptosis targets CPT-1 activity suppression mediated through diminishing the DNL pathway in HepG2 cells. In addition, increased ROS production was found after treatment with EGCG and EC, indicating oxidative stress mechanism induced apoptosis. The strong apoptotic effect of EGCG and EC was specifically absent in primary human hepatocytes. Conclusion: Our supportive evidence confirms potential alternative cancer treatments by EGCG and EC that selectively target the DNL pathway. PMID- 29588627 TI - Zymosan attenuates melanoma growth progression, increases splenocyte proliferation and induces TLR-2/4 and TNF-alpha expression in mice. AB - Background: Melanoma is one of the most common types of skin malignancies. Since current therapies are suboptimal, considerable interest has focused on novel natural-based treatments. Toll-like receptors (TLRs) play an important role in evoking innate immunity against cancer cells. Zymosan, a known TLR-2 agonist, is a glucan derived from yeast cell walls with promising immunomodulatory effects. The aim of this study was to evaluate whether Saccharomyces cerevisiae-derived zymosan-modulated skin melanoma progression by regulation of TLR-2 and TLR-4 expression in peritoneal macrophages and serum TNF-alpha level. Methods: Male C57BL/6 mice were divided into four groups: i) zymosan-treated (Z), ii) Melanoma bearing mice (M), iii) Melanoma-bearing mice treated with zymosan (ZM) and iv) a healthy control group (negative control). 15 days after melanoma induction, mice were injected i.p. with zymosan (10 MUg) daily for 4 consecutive days. Mice were CO2-euthanized and serum TNF-alpha level, TLR-2 and TLR-4 expression in peritoneal macrophages and tumor growth measured. Splenocytes were treated ex vivo with zymosan to determine viability and proliferation. Results: Tumor weight significantly decreased following therapeutic dosing with zymosan (P < 0.05). This was associated with zymosan-induced upregulation of TLR-2, TLR-4 and TNF alpha mRNA in peritoneal macrophages and enhanced serum TNF-alpha levels (P < 0.05). Splenocyte number and viability were increased in a concentration dependent manner by zymosan. Conclusions: Our study suggests that zymosan-induced upregulation of TLR-2, TLR-4 and TNF-alpha gene expression and of TNF-alpha release; together with increased level of lymphocyte proliferation may play a role in the inhibition of melanoma progression. PMID- 29588629 TI - Digital Technologies Supporting Person-Centered Integrated Care - A Perspective. AB - Shared electronic health and social care records in some service systems are already showing some of the benefits of digital technology and digital data for integrating health and social care. These records are one example of the beginning "digitalisation" of services that gives a glimpse of the potential of digital technology and systems for building coordinated and individualized integrated care. Yet the promise has been greater than the benefits, and progress has been slow compared to other industries. This paper describes for non technical readers how information technology was used to support integrated care schemes in six EU services, and suggests practical ways forward to use the new opportunities to build person-centered integrated care. PMID- 29588628 TI - A robust mass spectrometry method for rapid profiling of erythrocyte ghost membrane proteomes. AB - Background: Red blood cell (RBC) physiology is directly linked to many human disorders associated with low tissue oxygen levels or anemia including chronic obstructive pulmonary disease, congenital heart disease, sleep apnea and sickle cell anemia. Parasites such as Plasmodium spp. and phylum Apicomplexa directly target RBCs, and surface molecules within the RBC membrane are critical for pathogen interactions. Proteomics of RBC membrane 'ghost' fractions has therefore been of considerable interest, but protocols described to date are either suboptimal or too extensive to be applicable to a larger set of clinical cohorts. Methods: Here, we describe an optimised erythrocyte isolation protocol from blood, tested for various storage conditions and explored using different fractionation conditions for isolating ghost RBC membranes. Liquid chromatography mass spectrometry (LC-MS) analysis on a Q-Exactive Orbitrap instrument was used to profile proteins isolated from the comparative conditions. Data analysis was run on the MASCOT and MaxQuant platforms to assess their scope and diversity. Results: The results obtained demonstrate a robust method for membrane enrichment enabling consistent MS based characterisation of > 900 RBC membrane proteins in single LC-MS/MS analyses. Non-detergent based membrane solubilisation methods using the tissue and supernatant fractions of isolated ghost membranes are shown to offer effective haemoglobin removal as well as diverse recovery including erythrocyte membrane proteins of high and low abundance. Conclusions: The methods described in this manuscript propose a medium to high throughput framework for membrane proteome profiling by LC-MS of potential applicability to larger clinical cohorts in a variety of disease contexts. PMID- 29588630 TI - How to Improve Integrated Care for People with Chronic Conditions: Key Findings from EU FP-7 Project INTEGRATE and Beyond. AB - Background: Political and public health leaders increasingly recognize the need to take urgent action to address the problem of chronic diseases and multi morbidity. European countries are facing unprecedented demand to find new ways to deliver care to improve patient-centredness and personalization, and to avoid unnecessary time in hospitals. People-centred and integrated care has become a central part of policy initiatives to improve the access, quality, continuity, effectiveness and sustainability of healthcare systems and are thus preconditions for the economic sustainability of the EU health and social care systems. Purpose: This study presents an overview of lessons learned and critical success factors to policy making on integrated care based on findings from the EU FP-7 Project Integrate, a literature review, other EU projects with relevance to this study, a number of best practices on integrated care and our own experiences with research and policy making in integrated care at the national and international level. Results: Seven lessons learned and critical success factors to policy making on integrated care were identified. Conclusion: The lessons learned and critical success factors to policy making on integrated care show that a comprehensive systems perspective should guide the development of integrated care towards better health practices, education, research and policy. PMID- 29588631 TI - A Policy Guide on Integrated Care (PGIC): Lessons Learned from EU Project INTEGRATE and Beyond. AB - Efforts are underway in many European countries to channel efforts into creating improved integrated health and social care services. But most countries lack a strategic plan that is sustainable over time, and that reflects a comprehensive systems perspective. The Policy Guide on Integrated Care (PGIC) as presented in this paper resulted from experiences with the EU Project INTEGRATE and our own work with healthcare reform for patients with chronic conditions at the national and international level. This project is one of the largest EU funded projects on Integrated Care, conducted over a four-year period (2012-2016) and included partners from nine European countries. Project Integrate aimed to gain insights into the leadership, management and delivery of integrated care to support European care systems to respond to the challenges of ageing populations and the rise of people living with long-term conditions. The objective of this paper is to describe the PGIC as both a tool and a reasoning flow that aims at supporting policy makers at the national and international level with the development and implementation of integrated care. Any Policy Guide on Integrated should build upon three building blocks, being a mission, vision and a strategy that aim at capturing the large amount of factors that directly or indirectly influence the successful development of integrated care. PMID- 29588632 TI - Interprofessional Collaboration between General Physicians and Emergency Department Teams in Belgium: A Qualitative Study. AB - This study aimed to assess interprofessional collaboration between general physicians and emergency departments in the French speaking regions of Belgium. Eight group interviews were conducted both in rural and urban areas, including in Brussels. Findings showed that the relational components of collaboration, which are highly valued by individuals involved, comprise mutual acquaintanceship and trust, shared power and objectives. The organizational components of collaboration included out-of-hours services, role clarification, leadership and overall environment. Communication and patient's role were also found to be key elements in enhancing or hindering collaboration across these two levels of care. Relationships between general physicians and emergency departments' teams were tightly linked to organizational factors and the general macro-environment. Health system regulation did not appear to play a significant role in promoting collaboration between actors. A better role clarification is needed in order to foster multidisciplinary team coordination for a more efficient patient management. Finally, economic power and private practice impeded interprofessional collaboration between the care teams. In conclusion, many challenges need to be addressed for achievement of a better collaboration and more efficient integration. Not only should integration policies aim at reinforcing the role of general physicians as gatekeepers, also they should target patients' awareness and empowerment.

PMID- 29588634 TI - Planning for the Discharge, not for Patient Self-Management at Home - An Observational and Interview Study of Hospital Discharge. AB - Introduction and objective: Despite recent interest in care transitions, little is known about how patients are prepared for the self-management tasks following the hospitalization. The objective of the study was to explore how discharge information is prepared and provided to patients in the transition from hospital to home. Method: The discharge process at three hospitals in Sweden was observed over 12 days spread over ten weeks. In total, 30 discharge encounters were observed followed by interviews with patients and professionals. Data were analysed using qualitative content analysis. Results: Much time, effort and resources were used to prepare the discharge; home-going teams and registered nurses planned the practical and social aspects of the discharge and the physicians compiled a plain-language discharge letter. Less focus was given on the actual discharge information to the patients. The discharge encounters lasted for a median of 4:46 minutes and the information had a retrospective focus with information on the hospitalization period, though omitting self-management tasks and life-style advice. Conclusion: The discharge letter constitutes the basis for all patient information at discharge. The focus of the discharge encounter needs to be extended beyond mere information to include patient understanding, motivation and skills for self-management at home. PMID- 29588635 TI - Individualising Chronic Care Management by Analysing Patients' Needs - A Mixed Method Approach. AB - Background: Modern health systems are increasingly faced with the challenge to provide effective, affordable and accessible health care for people with chronic conditions. As evidence on the specific unmet needs and their impact on health outcomes is limited, practical research is needed to tailor chronic care to individual needs of patients with diabetes. Qualitative approaches to describe professional and informal caregiving will support understanding the complexity of chronic care. Results are intended to provide practical recommendations to be used for systematic implementation of sustainable chronic care models. Method: A mixed method study was conducted. A standardised survey (n = 92) of experts in chronic care using mail responses to open-ended questions was conducted to analyse existing chronic care programs focusing on effective, problematic and missing components. An expert workshop (n = 22) of professionals and scientists of a European funded research project MANAGE CARE was used to define a limited number of unmet needs and priorities of elderly patients with type 2 diabetes mellitus and comorbidities. This list was validated and ranked using a multilingual online survey (n = 650). Participants of the online survey included patients, health care professionals and other stakeholders from 56 countries. Results: The survey indicated that current care models need to be improved in terms of financial support, case management and the consideration of social care. The expert workshop identified 150 patient needs which were summarised in 13 needs dimensions. The online survey of these pre-defined dimensions revealed that financial issues, education of both patients and professionals, availability of services as well as health promotion are the most important unmet needs for both patients and professionals. Conclusion: The study uncovered competing demands which are not limited to medical conditions. The findings emphasise that future care models need to focus stronger on individual patient needs and promote their active involvement in co-design and implementation. Future research is needed to develop new chronic care models providing evidence-based and practical implications for the regional care setting. PMID- 29588636 TI - Enhancing Care Transitions for Older People through Interprofessional Simulation: A Mixed Method Evaluation. AB - Introduction: The educational needs of the health and social care workforce for delivering effective integrated care are important. This paper reports on the development, pilot and evaluation of an interprofessional simulation course, which aimed to support integrated care models for care transitions for older people from hospital to home. Theory and methods: The course development was informed by a literature review and a scoping exercise with the health and social care workforce. The course ran six times and was attended by health and social care professionals from hospital and community (n = 49). The evaluation aimed to elicit staff perceptions of their learning about care transfers of older people and to explore application of learning into practice and perceived outcomes. The study used a sequential mixed method design with questionnaires completed pre (n = 44) and post (n = 47) course and interviews (n = 9) 2-5 months later. Results: Participants evaluated interprofessional simulation as a successful strategy. Post-course, participants identified learning points and at the interviews, similar themes with examples of application in practice were: Understanding individual needs and empathy; Communicating with patients and families; Interprofessional working; Working across settings to achieve effective care transitions. Conclusions and discussion: An interprofessional simulation course successfully brought together health and social care professionals across settings to develop integrated care skills and improve care transitions for older people with complex needs from hospital to home. PMID- 29588639 TI - Contract Design: The problem of information asymmetry. AB - Introduction: Integrated care systems are advocated as an effective method of improving the performance of healthcare systems. These systems outline a payment and care delivery model that intends to tie provider reimbursements to predefined quality metrics. Little is known about the contractual design and the main challenges of delegating "accountability" to these new kinds of organisations and/or contracts. The research question in this article focuses on how healthcare contracts can look like and which possible problems arise in designing such contracts. In this a special interest is placed on information asymmetries. Methods: A comprehensive literature review on methods of designing contracts in Integrated Care was conducted. This article is the first in a row of three that all contribute to a specific issue in designing healthcare contracts. Starting with the organisation of contracts and information asymmetries, part 2 focusses on financial options and risks and part 3 finally concludes with the question of risk management and evaluation. Results: Healthcare contracting between providers and payers will have a major impact on the overall design of future healthcare systems. If Integrated care systems or any other similar concept of care delivery are to be contracted directly by payers to manage the continuum of care the costs of market utilisation play an essential role. Transaction costs also arise in the course of the negotiation and implementation of contracts. These costs are the reason why it is generally not possible to conclude perfect (complete) contracts. Problems with asymmetric distribution of information can relate to the situation before a contract is concluded (adverse selection) and after conclusion of a contract (moral hazard). Discussion and Conclusions: Information asymmetries are seen as a major obstacle to the efficient operation of integrated care programmes. Coordination and motivation problems cannot be solved at no-costs. The presented problems in the design of selective individual contracts represent a necessary but not a sufficient condition for further government intervention. A state or political failures have to be assumed continuously. PMID- 29588637 TI - Indicators and Measurement Tools for Health Systems Integration: A Knowledge Synthesis. AB - Background: Despite far reaching support for integrated care, conceptualizing and measuring integrated care remains challenging. This knowledge synthesis aimed to identify indicator domains and tools to measure progress towards integrated care. Methods: We used an established framework and a Delphi survey with integration experts to identify relevant measurement domains. For each domain, we searched and reviewed the literature for relevant tools. Findings: From 7,133 abstracts, we retrieved 114 unique tools. We found many quality tools to measure care coordination, patient engagement and team effectiveness/performance. In contrast, there were few tools in the domains of performance measurement and information systems, alignment of organizational goals and resource allocation. The search yielded 12 tools that measure overall integration or three or more indicator domains. Discussion: Our findings highlight a continued gap in tools to measure foundational components that support integrated care. In the absence of such targeted tools, "overall integration" tools may be useful for a broad assessment of the overall state of a system. Conclusions: Continued progress towards integrated care depends on our ability to evaluate the success of strategies across different levels and context. This study has identified 114 tools that measure integrated care across 16 domains, supporting efforts towards a unified measurement framework.

AB - Introduction: Integrated care systems as well as accountable care organisations (ACOs) in the US and similar concepts in other countries are advocated as an effective method of improving the performance of healthcare systems. These systems outline a payment and care delivery model that intends to tie provider reimbursements to predefined quality metrics. By this the total costs of care shall be reduced. When designing healthcare options contractors are faced with a variety of financial options. The costs of market utilisation are highly relevant for the conception of healthcare contracts; furthermore contract-specific investments are an obstacle to the efficient operation of ACOs. Methods: A comprehensive literature review on methods of designing contracts in Integrated Care was conducted. This article is the second in a row of three that are all published in this issue and contribute to a specific issue in designing healthcare contracts. The first dealt with the organisation of contracts and information asymmetries, while part 3 concludes with the question of risk management and evaluation. The specific research question of this second article focusses on the financial options and reimbursement schemes that are available to define healthcare contracts. Results: A healthcare contract is a relational contract, which determines the level of reimbursement, the scope of services and the quality between service providers and payers, taking account of the risks relating to population and performance. A relational contract is an agreement based upon assumption of a longer timeframe. A major obstacle to the practical implementation of healthcare contracts is the prognosis of the inflows and outflows due to the actuarial risks of the insured population. Financing conditions and reimbursement arrangements that are based on a prospectively determined fixed price, have a significant drawback: it is very difficult to take the differences in health status and the utilisation of distinct insured clientele (panel) into account. Discussion and Conclusion: The first two articles of this series on contract design have shown that complete contracts in healthcare are unrealistic. Healthcare reimbursement contracts are incomplete contracts with a high degree of uncertainty. In incomplete contracts specific contractual regulations are not made for any eventuality. For this reason it is important that the parties agree on the prevention of endogenous risks (asymmetric information after the conclusion of the contract) and on the procedure in the case of unforeseen circumstances (the risks of random, parameter risk and change risks to the healthcare program).

AB - Survivors of childhood and adult-onset cancer are at lifelong risk for the development of late effects of treatment that can lead to serious morbidity and premature mortality. Regular long-term follow-up aiming for prevention, early detection and intervention of late effects can preserve or improve health. The heterogeneous and often serious character of late effects emphasizes the need for specialized cancer survivorship care clinics. Multidisciplinary cancer survivorship care requires a coordinated and well integrated health care environment for risk based screening and intervention. In addition survivors engagement and adherence to the recommendations are also important elements. We developed an innovative model for integrated care for cancer survivors, the "Personalized Cancer Survivorship Care Model", that is being used in our clinic. This model comprises 1. Personalized follow-up care according to the principles of Person Centered Care, aiming to empower survivors and to support self management, and 2. Organization according to a multidisciplinary and risk based approach. The concept of person centered care is based on three components: initiating, integrating and safeguarding the partnership with the patient. This model has been developed as a universal model of care that will work for all cancer survivors in different health care systems. It could be used for studies to improve self efficacy and the cost-effectiveness of cancer survivorship care. PMID- 29588638 TI - Integrated Care Planning for Cancer Patients: A Scoping Review. AB - Introduction: There has been a growing emphasis on the use of integrated care plans to deliver cancer care. However little is known about how integrated care plans for cancer patients are developed including featured core activities, facilitators for uptake and indicators for assessing impact. Methods: Given limited consensus around what constitutes an integrated care plan for cancer patients, a scoping review was conducted to explore the components of integrated care plans and contextual factors that influence design and uptake. Results: Five types of integrated care plans based on the stage of cancer care: surgical, systemic, survivorship, palliative and comprehensive (involving a transition between stages) are described in current literature. Breast, esophageal and colorectal cancers were common disease sites. Multi-disciplinary teams, patient needs assessment and transitional planning emerged as key features. Provider buy in and training alongside informational technology support served as important facilitators for plan uptake. Provider-level measurement was considerably less robust compared to patient and system-level indicators. Conclusions: Similarities in design features, components and facilitators across the various types of integrated care plans indicates opportunities to leverage shared features and enable a management lens that spans the trajectory of a patient's journey rather than a phase-specific silo approach to care. PMID- 29588642 TI - Quasi-experimental Study of Systematic Screening for Family Planning Services among Postpartum Women Attending Village Health and Nutrition Days in Jharkhand, India. AB - Background: Systematic screening helps increase family planning uptake through integration with other services, including immunization. Though successfully demonstrated at health facilities, this strategy has not been demonstrated in communities. This study assessed the effectiveness of systematic screening to increase postpartum family planning use during community health days in India without adversely affecting immunization services. Methods: The study was conducted during 180 individual Village Health and Nutrition Days in Jharkhand, India. All health workers were trained in postpartum family planning counseling. Intervention providers were also trained in systematic screening. 217 postpartum women aged 15-49 years participated in baseline and endline exit interviews and routine service statistics were analyzed from 2,485 facility visits at affiliated health centers. Results: No difference in family planning service use was found in the intervention group, but significantly fewer interviewed women reported receiving family planning services at endline in the comparison group (p = 0.014). Family planning acceptance at affiliated health centers increased significantly in intervention areas (p < 0.001) but not in comparison areas, while immunization service use increased in both groups (p = 0.002 intervention, p < 0.001 comparison). Conclusions: The use of the postpartum systematic screening tool appears to increase acceptance of family planning services when integrated with community-based services in Jharkhand. PMID- 29588643 TI - Integrated Care to Address the Physical Health Needs of People with Severe Mental Illness: A Mapping Review of the Recent Evidence on Barriers, Facilitators and Evaluations. AB - People with mental health conditions have a lower life expectancy and poorer physical health outcomes than the general population. Evidence suggests this is due to a combination of clinical risk factors, socioeconomic factors, and health system factors, notably a lack of integration when care is required across service settings. Several recent reports have looked at ways to better integrate physical and mental health care for people with severe mental illness (SMI). We built on these by conducting a mapping review that looked for the most recent evidence and service models in this area. This involved searching the published literature and speaking to people involved in providing or using current services. Few of the identified service models were described adequately and fewer still were evaluated, raising questions about the replicability and generalisability of much of the existing evidence. However, some common themes did emerge. Efforts to improve the physical health care of people with SMI should empower staff and service users and help remove everyday barriers to delivering and accessing integrated care. In particular, there is a need for improved communication among professionals and better information technology to support them, greater clarity about who is responsible and accountable for physical health care, and greater awareness of the effects of stigmatisation on the wider culture and environment in which services are delivered. PMID- 29588644 TI - An Instrument to Measure Maturity of Integrated Care: A First Validation Study. AB - Introduction: Lessons captured from interviews with 12 European regions are represented in a new instrument, the B3-Maturity Model (B3-MM). B3-MM aims to assess maturity along 12 dimensions reflecting the various aspects that need to be managed in order to deliver integrated care. The objective of the study was to test the content validity of B3-MM as part of SCIROCCO (Scaling Integrated Care into Context), a European Union funded project. Methods: A literature review was conducted to compare B3-MM's 12 dimensions and their measurement scales with existing measures and instruments that focus on assessing the development of integrated care. Subsequently, a three-round survey conducted through a Delphi study with international experts in the field of integrated care was performed to test the relevance of: 1) the dimensions, 2) the maturity indicators and 3) the assessment scale used in B3-MM. Results: The 11 articles included in the literature review confirmed all the dimensions described in the original version of B3-MM. The Delphi study rounds resulted in various phrasing amendments of indicators and assessment scale. Full agreement among the experts on the relevance of the 12 B3-MM dimensions, their indicators, and assessment scale was reached after the third Delphi round. Conclusion and discussion: The B3-MM dimensions, maturity indicators and assessment scale showed satisfactory content validity. While the B3-MM is a unique instrument based on existing knowledge and experiences of regions in integrated care, further testing is needed to explore other measurement properties of B3-MM. PMID- 29588645 TI - Translating the Elements of Health Governance for Integrated Care from Theory to Practice: A Case Study Approach. AB - Introduction: Against a paucity of evidence, a model describing elements of health governance best suited to achieving integrated care internationally was developed. The aim of this study was to explore how health meso-level organisations used, or planned to use, the governance elements. Methods: A case study design was used to offer two contrasting contexts of health governance. Semi-structured interviews were conducted with participants who held senior governance roles. Data were thematically analysed to identify if the elements of health governance were being used, or intended to be in the future. Results: While all participants agreed that the ten elements were essential to developing future integrated care, most were not used. Three major themes were identified: (1) organisational versus system focus, (2) leadership and culture, and, (3) community (dis)engagement. Discussion: Several barriers and enablers to the use of the elements were identified and would require addressing in order to make evidence-based changes. Conclusion: Despite a clear international policy direction in support of integrated care this study identified a number of significant barriers to its implementation. The study reconfirmed that a focus on all ten elements of health governance is essential to achieve integrated care. PMID- 29588646 TI - Patient Involvement in Geriatric Care - Results and Experiences from a Mixed Models Design Study within Project INTEGRATE. AB - Introduction: Patient involvement is a core component of an integrated care approach. While the benefits and prerequisites of patient involvement have been described in general and additionally for some target populations, little is known about the views and experiences of older people regarding this matter. Methods: A study with a mixed-methods design was conducted to gain a better understanding about patient involvement in geriatric care. A questionnaire on shared decision-making was administered within a group of older adults in Germany. Additionally, 7 focus groups with health professionals and geriatric patients in Germany and Estonia were held to deepen the insight of the questionnaire and discussing experiences and barriers of patient involvement. Results: Older people without an actual medical problem expressed a significantly higher desire to participate in shared decisions than those requiring actual medical care. No significant differences could be found for the desire to be informed as part of the care process. No correlation between patients' desire and experiences on shared decision-making could be observed. In the focus groups, patients demanded a comprehensive and understandable information and education process while the health professionals' view was very task-specific. This conflict led to a loss of trust by the patients. Conclusions: There is a gap between patients' and health professionals' views on patient involvement in older people. The involvement process should therefore be comprehensive and should take into account different levels of health literacy. PMID- 29588648 TI - Flexibility of foraging strategies of the great skua Stercorarius skua breeding in the largest colony in the Barents Sea region. AB - Background: Foraging strategies of seabird species often vary considerably between and within individuals. This variability is influenced by a multitude of factors including age, sex, stage of annual life cycle, reproductive status, individual specialization and environmental conditions. Results: Using GPS loggers, we investigated factors affecting foraging flight characteristics (total duration, maximal range, total distance covered) of great skuas Stercorarius skua of known sex breeding on Bjornoya, Svalbard, the largest colony in the Barents Sea region. We examined influence of sex (females are larger than males), phase of breeding (incubation, chick-rearing), reproductive status (breeders, failed breeders) and bird ID (they are known for individual foraging specialization). Our analyses revealed that only bird ID affected foraging flight characteristics significantly, indicating a high degree of plasticity regardless of sex, reproductive status or phase of breeding. We recognized three main groups of individuals: 1) those preying mainly on other seabirds in the breeding colonies (6%), 2) those foraging at sea (76%) and kleptoparasiting other seabirds and/or foraging on fish and/or offal discarded by fishing vessels, and 3) those alternating between preying on other seabirds in breeding colonies and foraging at sea (18%). Despite marked size sexual dimorphism, we found no apparent sex differences in flight characteristics. Birds after egg- or chick-loss and thus not constrained as central foragers did not modify their foraging flights. Conclusions: Great skuas breeding on Bjornoya displayed a high degree of plasticity regardless of sex, reproductive status or phase of breeding. We recognized groups of individuals regularly preying in the seabird colonies, foraging at sea, and alternating between both strategies. This suggests foraging specialization of some individuals. PMID- 29588649 TI - Classification of CITES-listed and other neotropical Meliaceae wood images using convolutional neural networks. AB - Background: The current state-of-the-art for field wood identification to combat illegal logging relies on experienced practitioners using hand lenses, specialized identification keys, atlases of woods, and field manuals. Accumulation of this expertise is time-consuming and access to training is relatively rare compared to the international demand for field wood identification. A reliable, consistent and cost effective field screening method is necessary for effective global scale enforcement of international treaties such as the Convention on the International Trade in Endagered Species (CITES) or national laws (e.g. the US Lacey Act) governing timber trade and imports. Results: We present highly effective computer vision classification models, based on deep convolutional neural networks, trained via transfer learning, to identify the woods of 10 neotropical species in the family Meliaceae, including CITES listed Swietenia macrophylla, Swietenia mahagoni, Cedrela fissilis, and Cedrela odorata. We build and evaluate models to classify the 10 woods at the species and genus levels, with image-level model accuracy ranging from 87.4 to 97.5%, with the strongest performance by the genus-level model. Misclassified images are attributed to classes consistent with traditional wood anatomical results, and our species-level accuracy greatly exceeds the resolution of traditional wood identification. Conclusion: The end-to-end trained image classifiers that we present discriminate the woods based on digital images of the transverse surface of solid wood blocks, which are surfaces and images that can be prepared and captured in the field. Hence this work represents a strong proof-of-concept for using computer vision and convolutional neural networks to develop practical models for field screening timber and wood products to combat illegal logging. PMID- 29588650 TI - Outlier detection in BLAST hits. AB - Background: An important task in a metagenomic analysis is the assignment of taxonomic labels to sequences in a sample. Most widely used methods for taxonomy assignment compare a sequence in the sample to a database of known sequences. Many approaches use the best BLAST hit(s) to assign the taxonomic label. However, it is known that the best BLAST hit may not always correspond to the best taxonomic match. An alternative approach involves phylogenetic methods, which take into account alignments and a model of evolution in order to more accurately define the taxonomic origin of sequences. Similarity-search based methods typically run faster than phylogenetic methods and work well when the organisms in the sample are well represented in the database. In contrast, phylogenetic methods have the capability to identify new organisms in a sample but are computationally quite expensive. Results: We propose a two-step approach for metagenomic taxon identification; i.e., use a rapid method that accurately classifies sequences using a reference database (this is a filtering step) and then use a more complex phylogenetic method for the sequences that were unclassified in the previous step. In this work, we explore whether and when using top BLAST hit(s) yields a correct taxonomic label. We develop a method to detect outliers among BLAST hits in order to separate the phylogenetically most closely related matches from matches to sequences from more distantly related organisms. We used modified BILD (Bayesian Integral Log-Odds) scores, a multiple alignment scoring function, to define the outliers within a subset of top BLAST hits and assign taxonomic labels. We compared the accuracy of our method to the RDP classifier and show that our method yields fewer misclassifications while properly classifying organisms that are not present in the database. Finally, we evaluated the use of our method as a pre-processing step before more expensive phylogenetic analyses (in our case TIPP) in the context of real 16S rRNA datasets. Conclusion: Our experiments make a good case for using a two-step approach for accurate taxonomic assignment. We show that our method can be used as a filtering step before using phylogenetic methods and provides a way to interpret BLAST results using more information than provided by E-values and bit scores alone. PMID- 29588647 TI - STAT3, stem cells, cancer stem cells and p63. AB - Signal Transducer and Activator of Transcription 3 (STAT3) is a transcription factor with many important functions in the biology of normal and transformed cells. Its regulation is highly complex as it is involved in signaling pathways in many different cell types and under a wide variety of conditions. Besides other functions, STAT3 is an important regulator of normal stem cells and cancer stem cells. p63 which is a member of the p53 protein family is also involved in these functions and is both physically and functionally connected with STAT3. This review summarizes STAT3 function and regulation, its role in stem cell and cancer stem cell properties and highlights recent reports about its relationship to p63. PMID- 29588651 TI - FSH: fast spaced seed hashing exploiting adjacent hashes. AB - Background: Patterns with wildcards in specified positions, namely spaced seeds, are increasingly used instead of k-mers in many bioinformatics applications that require indexing, querying and rapid similarity search, as they can provide better sensitivity. Many of these applications require to compute the hashing of each position in the input sequences with respect to the given spaced seed, or to multiple spaced seeds. While the hashing of k-mers can be rapidly computed by exploiting the large overlap between consecutive k-mers, spaced seeds hashing is usually computed from scratch for each position in the input sequence, thus resulting in slower processing. Results: The method proposed in this paper, fast spaced-seed hashing (FSH), exploits the similarity of the hash values of spaced seeds computed at adjacent positions in the input sequence. In our experiments we compute the hash for each positions of metagenomics reads from several datasets, with respect to different spaced seeds. We also propose a generalized version of the algorithm for the simultaneous computation of multiple spaced seeds hashing. In the experiments, our algorithm can compute the hashing values of spaced seeds with a speedup, with respect to the traditional approach, between 1.6[Formula: see text] to 5.3[Formula: see text], depending on the structure of the spaced seed. Conclusions: Spaced seed hashing is a routine task for several bioinformatics application. FSH allows to perform this task efficiently and raise the question of whether other hashing can be exploited to further improve the speed up. This has the potential of major impact in the field, making spaced seed applications not only accurate, but also faster and more efficient. Availability: The software FSH is freely available for academic use at: https://bitbucket.org/samu661/fsh/overview. PMID- 29588652 TI - What is the treatment of tracheal lesions associated with traditional thyroidectomy? Case report and systematic review. AB - Aim: The aim of this study is to review the literature focusing on various treatments based on time of tracheal injury and on different surgeons' personal experience. Methods: We retrospectively reviewed all cases of total thyroidectomy performed at the University Surgical Department of Ospedali Riuniti of Foggia from 2006 to 2017. Only a single case of tracheal lesion due to traditional total thyroidectomy was found. An extensive search of the relevant literature was carried out using MEDLINE (PubMed). We included articles that reported article type, patient number, sex, age, reasons for surgery, time of tracheal perforation intraoperatively or delayed rupture, symptoms, diagnosis, type of surgical procedure, pathological report and follow-up. Results: A total of 156 published studies were screened from the sources listed. Of these, 15 studies were included in the present study. We introduced our case in the analysis. A total of 16 patients were totally analysed. There were seven males (43.7%) and seven females (43.7%), and for two patients, gender was not available. The mean patient age was 41.6 years. Conclusions: The literature review showed very few cases treated differently. However, it would be good to standardise treatments. Tracheal perforation, if encountered, needs to be managed appropriately in centres of expertise with a high volume of thyroidectomies. PMID- 29588653 TI - Approaches in studying the pharmacology of Chinese Medicine formulas: bottom-up, top-down-and meeting in the middle. AB - Investigating the pharmacology is key to the modernization of Chinese Medicine (CM) formulas. However, identifying which are the active compound(s) of CM formulas, which biological entities they target, and through which signaling pathway(s) they act to modify disease symptoms, are still difficult tasks for researchers, even when equipped with an arsenal of advanced modern technologies. Multiple approaches, including network pharmacology, pharmaco-genomics, proteomics, and -metabolomics, have been developed to study the pharmacology of CM formulas. They fall into two general categories in terms of how they tackle a problem: bottom-up and top-down. In this article, we compared these two different approaches in several dimensions by using the case of MaZiRenWan (MZRW, also known as Hemp Seed Pill), a CM herbal formula for functional constipation. Multiple hypotheses are easy to be proposed in the bottom-up approach (e.g. network pharmacology); but these hypotheses are usually false positives and hard to be tested. In contrast, it is hard to suggest hypotheses in the top-down approach (e.g. pharmacometabolomics); however, once a hypothesis is proposed, it is much easier to be tested. Merging of these two approaches could results in a powerful approach, which could be the new paradigm for the pharmacological study of CM formulas. PMID- 29588654 TI - Psoriasis therapy by Chinese medicine and modern agents. AB - Psoriasis is a chronic, painful, disfiguring and non-contagious skin disease that has globally affected at least 200 million patients. In general, mild to moderate psoriasis patients will be treated by chemical drugs or Chinese medicine, while targeting systemic biological drugs have been successfully developed with good efficacy but high cost burden to patients with severe psoriasis. Since the underlying mechanisms of psoriasis are not well understood, in this review, psoriasis pathogenesis and clinical therapeutic principles by modern medicine and Chinese medicine are extensively described. Based on the data from the China Food and Drug Administration, the majority of chemical drugs are utilized as the topical formulations, while Chinese medicines are mainly delivered by an oral route, suggesting that the market for topical preparations of Chinese medicine to treat psoriasis is worth to exploration. Moreover, considering the unique clinical therapeutic theory and successful clinical application of Chinese medicine in the treatment of psoriasis, we believe that development of new small molecule drugs based on Chinese medicine will be a promising strategy to reduce therapeutic costs and improve safety for psoriatic patients. PMID- 29588655 TI - Reflections from the Lebanese field: "First, heal thyself". AB - Humanitarian aid workers caring for Syrian refugees face major stressors as they attend to refugees' needs on the field. Without adequate psychosocial support, evidence has shown that fieldworkers experience high burnout and turnover as well as long-term poor mental health. Unfortunately, scarce training in this regard leaves them ill-equipped to care for themselves and practice resilience while handling trauma in the field. This paper highlights our reflection on working with mindfulness programs during humanitarian crises, specifically how our program, Stress Management and Relaxation Response Training (SMART), has helped over time fieldworkers and the community they cared for. We propose that programs targeting the wellbeing of fieldworkers should be prioritized as part of efforts to improve the international aid response although they may require impeccable coordination and generous resources. We encourage donors to fund those projects viewed as special social protection programs building resilience and strengthening within system support. We argue that this will increase the efficacy of the crisis intervention and work towards sustainable peace building. PMID- 29588656 TI - Involuntary admission in Norwegian adult psychiatric hospitals: a systematic review. AB - Background: It is an important objective of the psychiatric services to keep the use of involuntary procedures to a minimum, as the use of coercion involves clinical, ethical, and legal issues. It has been claimed that Norway has a relatively high rate of involuntary admissions. We reviewed the peer-reviewed literature on the use of involuntary admission in Norway, with the purpose of identifying the current state of knowledge and areas in need of further research. Methods: A systematic review following the PRISMA statement was conducted. We searched the electronic databases PsycInfo, PubMed, Web of Science, CINAHL, and Embase for studies relating to involuntary admission to Norwegian adult psychiatric hospitals published in the period 1 January 2001 to 8 August 2016. The database searches were supplemented with manual searches of relevant journals, reference lists, and websites. Results: Seventy-four articles were included and grouped into six categories based on their main topics: Patients' experiences, satisfaction and perceived coercion (21 articles), the Referral and admission process (11 articles), Rates of admission (8 articles), Characteristics of the patients (17 articles), Staff attitudes (9 articles), and Outcomes (8 articles). Four of the included articles described intervention studies. Fifty seven of the articles had a quantitative design, 16 had a qualitative design, and one a mixed-method design. There was a broad range of topics that were studied and considerable variation in study designs. The findings were largely in line with the international literature, but the particularities of Norwegian legislation and the Norwegian health services were reflected in the literature. The four intervention studies explored interventions for reducing rates of involuntary admission, such as modifying referring routines, improving patient information procedures, and increasing patients' say in the admission process, and represent an important avenue for future research on involuntary admission in Norway. Conclusions: The review suggests that Norway has a relatively high rate of involuntary admissions. The identified studies represent a broad mix of topics and designs. Four intervention studies were identified. More studies with strong designs are needed to bring research on involuntary admission in Norway to a next level. PMID- 29588657 TI - Feasibility study of a family- and school-based intervention for child behavior problems in Nepal. AB - Background: This study evaluates the feasibility, acceptability, and outcomes of a combined school- and family-based intervention, delivered by psychosocial counselors, for children with behavior problems in rural Nepal. Methods: Forty one children participated at baseline. Two students moved to another district, meaning 39 children, ages 6-15, participated at both baseline and follow-up. Pre post evaluation was used to assess behavioral changes over a 4-month follow-up period (n = 39). The primary outcome measure was the Disruptive Behavior International Scale-Nepal version (DBIS-N). The secondary outcome scales included the Child Functional Impairment Scale and the Eyberg Child Behavior Inventory (ECBI). Twelve key informant interviews were conducted with community stakeholders, including teachers, parents, and community members, to assess stakeholders' perceptions of the intervention. Results: The study found that children's behavior problems as assessed on the DBIS-N were significantly lower at follow-up (M = 13.0, SD = 6.4) than at baseline (M = 20.5, SD = 3.8), p < 0.001, CI [5.57, 9.35]. Similarly, children's ECBI Intensity scores were significantly lower at follow-up (M = 9.9, SD = 8.5) than at baseline (M = 14.8, SD = 7.7), p < 0.005, 95% CI [1.76, 8.14]. The intervention also significantly improved children's daily functioning. Parents and teachers involved in the intervention found it acceptable and feasible for delivery to their children and students. Parents and teachers reported improved behaviors among children and the implementation of new behavior management techniques both at home and in the classroom. Conclusions: Significant change in child outcome measures in this uncontrolled evaluation, alongside qualitative findings suggesting feasibility and acceptability, support moving toward a controlled trial to determine effectiveness. PMID- 29588658 TI - From nano- to micrometer scale: the role of microwave-assisted acid and alkali pretreatments in the sugarcane biomass structure. AB - Background: To date, great strides have been made in elucidating the role of thermochemical pretreatments in the chemical and structural features of plant cell walls; however, there is no clear picture of the plant recalcitrance and its relationship to deconstruction. Previous studies precluded full answers due to the challenge of multiscale features of plant cell wall organization. Complementing the previous efforts, we undertook a systematic, multiscale, and integrated approach to track the effect of microwave-assisted H2SO4 and NaOH treatments on the hierarchical structure of plants, i.e., from a nano- to micrometer scale. We focused on the investigation of the highly recalcitrant sclerenchyma cell walls from sugarcane bagasse. Results: Through atomic force microscopy and X-ray diffraction analyses, remarkable details of the assembly of cellulose microfibrils not previously seen were revealed. Following the H2SO4 treatment, we observed that cellulose microfibrils were almost double the width of the alkali pretreated sample at the temperature of 160 degrees C. Such enlargement led to a greater contact between cellulose chains, with a subsequent molecule alignment, as indicated by the X-ray diffraction (XRD) results with the conspicuous expansion of the average crystallite size. The delignification process had little effect on the local nanometer-sized arrangement of cellulose molecules. However, the rigidity and parallel alignment of cellulose microfibrils were partially degraded. The XRD analysis also agrees with these findings as evidenced by large momentum transfer vectors (q > 20 nm-1), interpreted as indicators of the long-range order of cell wall components, which were similar for all the studied samples except with application of the NaOH treatment at 160 degrees C. These changes were followed by the eventual swelling of the fiber cell walls. Conclusions: Based on an integrated approach, we presented multidimensional architectural models of cell wall deconstruction resulting from microwave-assisted pretreatments. We provided direct evidence supporting the idea that hemicellulose is the main barrier for the swelling of cellulose microfibrils, whereas lignin adds rigidity to cell walls. Our findings shed light on the design of more efficient strategies, not only for the conversion of biomass to fuels but also for the production of nanocellulose, which has great potential for several applications such as composites, rheology modifiers, and pharmaceuticals. PMID- 29588659 TI - A novel acetyl xylan esterase enabling complete deacetylation of substituted xylans. AB - Background: Acetylated 4-O-(methyl)glucuronoxylan (GX) is the main hemicellulose in deciduous hardwood, and comprises a beta-(1->4)-linked xylopyranosyl (Xylp) backbone substituted by both acetyl groups and alpha-(1->2)-linked 4-O methylglucopyranosyluronic acid (MeGlcpA). Whereas enzymes that target singly acetylated Xylp or doubly 2,3-O-acetyl-Xylp have been well characterized, those targeting (2-O-MeGlcpA)3-O-acetyl-Xylp structures in glucuronoxylan have remained elusive. Results: An unclassified carbohydrate esterase (FjoAcXE) was identified as a protein of unknown function from a polysaccharide utilization locus (PUL) otherwise comprising carbohydrate-active enzyme families known to target xylan. FjoAcXE was shown to efficiently release acetyl groups from internal (2-O MeGlcpA)3-O-acetyl-Xylp structures, an activity that has been sought after but lacking in known carbohydrate esterases. FjoAcXE action boosted the activity of alpha-glucuronidases from families GH67 and GH115 by five and nine times, respectively. Moreover, FjoAcXE activity was not only restricted to GX, but also deacetylated (3-O-Araf)2-O-acetyl-Xylp of feruloylated xylooligomers, confirming the broad substrate range of this new carbohydrate esterase. Conclusion: This study reports the discovery and characterization of the novel carbohydrate esterase, FjoAcXE. In addition to cleaving singly acetylated Xylp, and doubly 2,3 O-acetyl-Xylp, FjoAcXE efficiently cleaves internal 3-O-acetyl-Xylp linkages in (2-O-MeGlcpA)3-O-acetyl-Xylp residues along with densely substituted and branched xylooligomers; activities that until now were missing from the arsenal of enzymes required for xylan conversion. PMID- 29588660 TI - Lignolytic-consortium omics analyses reveal novel genomes and pathways involved in lignin modification and valorization. AB - Background: Lignin is a heterogeneous polymer representing a renewable source of aromatic and phenolic bio-derived products for the chemical industry. However, the inherent structural complexity and recalcitrance of lignin makes its conversion into valuable chemicals a challenge. Natural microbial communities produce biocatalysts derived from a large number of microorganisms, including those considered unculturable, which operate synergistically to perform a variety of bioconversion processes. Thus, metagenomic approaches are a powerful tool to reveal novel optimized metabolic pathways for lignin conversion and valorization. Results: The lignin-degrading consortium (LigMet) was obtained from a sugarcane plantation soil sample. The LigMet taxonomical analyses (based on 16S rRNA) indicated prevalence of Proteobacteria, Actinobacteria and Firmicutes members, including the Alcaligenaceae and Micrococcaceae families, which were enriched in the LigMet compared to sugarcane soil. Analysis of global DNA sequencing revealed around 240,000 gene models, and 65 draft bacterial genomes were predicted. Along with depicting several peroxidases, dye-decolorizing peroxidases, laccases, carbohydrate esterases, and lignocellulosic auxiliary (redox) activities, the major pathways related to aromatic degradation were identified, including benzoate (or methylbenzoate) degradation to catechol (or methylcatechol), catechol ortho-cleavage, catechol meta-cleavage, and phthalate degradation. A novel Paenarthrobacter strain harboring eight gene clusters related to aromatic degradation was isolated from LigMet and was able to grow on lignin as major carbon source. Furthermore, a recombinant pathway for vanillin production was designed based on novel gene sequences coding for a feruloyl-CoA synthetase and an enoyl-CoA hydratase/aldolase retrieved from the metagenomic data set. Conclusion: The enrichment protocol described in the present study was successful for a microbial consortium establishment towards the lignin and aromatic metabolism, providing pathways and enzyme sets for synthetic biology engineering approaches. This work represents a pioneering study on lignin conversion and valorization strategies based on metagenomics, revealing several novel lignin conversion enzymes, aromatic-degrading bacterial genomes, and a novel bacterial strain of potential biotechnological interest. The validation of a biosynthetic route for vanillin synthesis confirmed the applicability of the targeted metagenome discovery approach for lignin valorization strategies. PMID- 29588661 TI - Enhancing the catalytic activity of a novel GH5 cellulase GtCel5 from Gloeophyllum trabeum CBS 900.73 by site-directed mutagenesis on loop 6. AB - Background: Cellulases of glycosyl hydrolase (GH) family 5 share a (beta/alpha)8 TIM-barrel fold structure with eight betaalpha loops surrounding the catalytic pocket. These loops exposed on the surface play a vital role in protein functions, primarily due to the interactions of some key amino acids with solvent and ligand molecules. It has been reported that motions of these loops facilitate substrate access and product release, and loops 6 and 7 located at the substrate entrance of the binding pocket promote proton transfer reaction at the catalytic site motions. However, the role of these flexible loops in catalysis of GH5 cellulase remains to be explored. Results: In the present study, an acidic, mesophilic GH5 cellulase (with optimal activity at pH 4.0 and 70 degrees C), GtCel5, was identified in Gloeophyllum trabeum CBS 900.73. The specific activities of GtCel5 toward CMC-Na, barley beta-glucan, and lichenan were 1117 +/ 43, 6257 +/- 26 and 5318 +/- 54 U/mg, respectively. Multiple sequence alignment indicates that one amino acid residue at position 233 on the loop 6 shows semi conservativeness and might contribute to the great catalytic performance. Saturation mutagenesis at position 233 was then conducted to reveal the vital roles of this position in enzyme properties. In comparison to the wild type, variants N233A and N233G showed decreased optimal temperature (- 10 degrees C) but increased activities (27 and 70%) and catalytic efficiencies (kcat/Km; 45 and 52%), respectively. The similar roles of position 233 in catalytic performance were also verified in the other two GH5 homologs, TeEgl5A and PoCel5, by reverse mutation. Further molecular dynamics simulations suggested that the substitution of asparagine with alanine or glycine may introduce more hydrogen bonds, increase the flexibility of loop 6, enhance the interactions between enzyme and substrate, and thus improve the substrate affinity and catalytic efficiency. Conclusion: This study proposed a novel cellulase with potentials for industrial application. A specific position was identified to play key roles in cellulase-substrate interactions and enzyme catalysis. It is of great importance for understanding the binding mechanism of GH5 cellulases, and provides an effective strategy to improve the catalytic performance of cellulases. PMID- 29588662 TI - Bridging the gap between feedstock growers and users: the study of a coppice poplar-based biorefinery. AB - Background: In the biofuel industry, land productivity is important to feedstock growers and conversion process product yield is important to the biorefinery. The crop productivity, however, may not positively correlate with bioconversion yield. Therefore, it is important to evaluate sugar yield and biomass productivity. In this study, 2-year-old poplar trees harvested in the first coppice cycle, including one low-productivity hybrid and one high-productivity hybrid, were collected from two poplar tree farms. Through steam pretreatment and enzymatic hydrolysis, the bioconversion yields of low- and high-productivity poplar hybrids were compared for both sites. Results: The low-productivity hybrids had 9-19% higher sugar yields than the high-productivity hybrids, although they have the similar chemical composition. Economic calculations show the impact on the plantation and biorefinery of using the two feedstocks. Growing a high-productivity hybrid means the land owner would use 11-26% less land (which could be used for other crops) or collect $2.53-$3.46 MM/year extra revenue from the surplus feedstock. On the other side, the biorefinery would receive 5-10% additional revenue using the low-productivity hybrid. Conclusion: We propose a business model based on the integration of the plantation and the biorefinery. In this model, different feedstocks are assessed using a metric of product tonnage per unit land per year. Use of this new economic metric bridges the gap between feedstock growers and users to maximize the overall production efficiency. PMID- 29588663 TI - A long noncoding RNA promotes cellulase expression in Trichoderma reesei. AB - Background: Due to its capability to secrete large quantities of plant biomass degrading enzymes (PBDE), Trichoderma reesei is widely applied for industrial purposes. In nature, expression of PBDE is efficiently regulated in this fungus. Several factors involved in this regulatory network have been identified. However, most of them are transcription factors. Long noncoding RNAs (lncRNAs) emerged as common players acting on epigenetic or transcriptional regulation in several eukaryotic organisms. To date, no lncRNA has been described in filamentous fungi. Results: A lncRNA termed HAX1 was identified in T. reesei QM9414. In this study, it was characterized and evidence for its regulatory impact on cellulase expression was provided. Interestingly, different versions of HAX1 were identified in different strains (namely, QM6a, QM9414, and Rut-C30), varying in terms of RNA length. Remarkably, considerable longer variants of this lncRNA are present in hypercellulolytic strains compared to the wild-type strain QM6a. Based on these results, a correlation between RNA length and the functional impact of HAX1 on PBDE expression was supposed. This assumption was verified by overexpressing the most abundant HAX1 versions identified in QM6a, QM9414, and Rut-C30. Such HAX1 overexpression on the one hand was suitable for regaining the function in hax1 disruption strains, and on the other hand resulted in notably higher cellulase activities in QM6a, especially by the expression of longer HAX1 versions. Conclusion: With HAX1, for the first time the regulatory role of a lncRNA in filamentous fungi was uncovered. Besides this, a new player involved in the complex regulation of PBDE expression in T. reesei was identified. Due to its enhancing effect on cellulase activity, HAX1 was shown to be not only interesting for basic research, but also a promising candidate for expanding the set of biotechnological tools for industrial application of T. reesei. PMID- 29588664 TI - A fast and sensitive activity assay for lytic polysaccharide monooxygenase. AB - Background: Lytic polysaccharide monooxygenases (LPMO) release a spectrum of cleavage products from their polymeric substrates cellulose, hemicellulose, or chitin. The correct identification and quantitation of these released products is the basis of MS/HPLC-based detection methods for LPMO activity. The duration, effort, and intricate analysis allow only specialized laboratories to measure LPMO activity in day-to-day work. A spectrophotometric assay will simplify the screening for LPMO in culture supernatants, help monitor recombinant LPMO expression and purification, and support enzyme characterization. Results: Based on a newly discovered peroxidase activity of LPMO, we propose a fast, robust, and sensitive spectrophotometric activity assay using 2,6-dimethoxyphenol (2,6-DMP) and H2O2. The fast enzymatic assay (300 s) consists of 1 mM 2,6-DMP as chromogenic substrate, 100 uM H2O2 as cosubstrate, and an adequate activity of LPMO in a suitable buffer. The high molar absorption coefficient of the formed product coerulignone (epsilon469 = 53,200 M-1 cm-1) makes the assay sensitive and allows reliable activity measurements of LPMO in concentrations of approx. 0.5-50 mg L-1. Conclusions: The activity assay based on 2,6-DMP detects a novel peroxidase activity of LPMO. This activity can be accurately measured and used for enzyme screening, production, and purification, and can also be applied to study binding constants or thermal stability. However, the assay has to be used with care in crude extracts, because other enzymes such as laccase or peroxidase will interfere with the assay. We also want to stress that the peroxidase activity is a homogeneous reaction with soluble substrates and should not be correlated to heterogeneous LPMO activity on polymeric substrates. PMID- 29588666 TI - Foreword. PMID- 29588665 TI - The diversity and specificity of the extracellular proteome in the cellulolytic bacterium Caldicellulosiruptor bescii is driven by the nature of the cellulosic growth substrate. AB - Background: Caldicellulosiruptor bescii is a thermophilic cellulolytic bacterium that efficiently deconstructs lignocellulosic biomass into sugars, which subsequently can be fermented into alcohols, such as ethanol, and other products. Deconstruction of complex substrates by C. bescii involves a myriad of highly abundant, substrate-specific extracellular solute binding proteins (ESBPs) and carbohydrate-active enzymes (CAZymes) containing carbohydrate-binding modules (CBMs). Mass spectrometry-based proteomics was employed to investigate how these substrate recognition proteins and enzymes vary as a function of lignocellulosic substrates. Results: Proteomic analysis revealed several key extracellular proteins that respond specifically to either C5 or C6 mono- and polysaccharides. These include proteins of unknown functions (PUFs), ESBPs, and CAZymes. ESBPs that were previously shown to interact more efficiently with hemicellulose and pectin were detected in high abundance during growth on complex C5 substrates, such as switchgrass and xylan. Some proteins, such as Athe_0614 and Athe_2368, whose functions are not well defined were predicted to be involved in xylan utilization and ABC transport and were significantly more abundant in complex and C5 substrates, respectively. The proteins encoded by the entire glucan degradation locus (GDL; Athe_1857, 1859, 1860, 1865, 1867, and 1866) were highly abundant under all growth conditions, particularly when C. bescii was grown on cellobiose, switchgrass, or xylan. In contrast, the glycoside hydrolases Athe_0609 (Pullulanase) and 0610, which both possess CBM20 and a starch binding domain, appear preferential to C5/complex substrate deconstruction. Some PUFs, such as Athe_2463 and 2464, were detected as highly abundant when grown on C5 substrates (xylan and xylose), also suggesting C5-substrate specificity. Conclusions: This study reveals the protein membership of the C. bescii secretome and demonstrates its plasticity based on the complexity (mono-/disaccharides vs. polysaccharides) and type of carbon (C5 vs. C6) available to the microorganism. The presence or increased abundance of extracellular proteins as a response to specific substrates helps to further elucidate C. bescii's utilization and conversion of lignocellulosic biomass to biofuel and other valuable products. This includes improved characterization of extracellular proteins that lack discrete functional roles and are poorly/not annotated. PMID- 29588667 TI - Intravascular Ultrasound Versus Optical Coherence Tomography for Coronary Artery Imaging - Apples and Oranges? AB - Intravascular imaging has advanced our understanding of coronary artery disease and facilitated decision-making in percutaneous coronary intervention (PCI). In particular, intravascular ultrasound (IVUS) has contributed significantly to modern PCI techniques. The recent introduction of optical coherence tomography (OCT) has further expanded this field due to its higher resolution and rapid image acquisition as compared with IVUS. Furthermore, OCT allows detailed planning of interventional strategies and optimisation before stent deployment, particularly with complex lesions. However, to date it is unclear whether OCT is superior to IVUS as an intracoronary imaging modality with limited data supporting OCT use in routine clinical practice. This review aims to compare these two intracoronary imaging techniques and the recent evidence for their use in this ever-changing field within interventional cardiology. PMID- 29588668 TI - Percutaneous Coronary Intervention in Patients Who Have an Indication for Oral Anticoagulation - an Evidence-based Approach to Antithrombotic Therapy. AB - Dual antiplatelet therapy (DAPT) is required following percutaneous coronary intervention (PCI) to prevent stent thrombosis. The optimal antithrombotic therapy following PCI for patients with an indication for long-term oral anticoagulation (OAC) is uncertain. DAPT and OAC, a combination known as 'triple therapy', reduces cardiovascular event rates but is associated with a substantial risk of bleeding. Recent data suggest that the duration of DAPT (and thereby triple therapy in those who also require OAC) can be limited to 1-3 months following new-generation drug-eluting stent deployment, and that aspirin may be omitted from triple therapy, without increasing the rate of ischaemic cardiovascular events. The increasing use of non-vitamin K antagonist oral anticoagulants and new antiplatelet agents (prasugrel and ticagrelor) has further complicated antithrombotic prescribing. This article aims to provide a summary of the evidence regarding antithrombotic therapy after PCI in patients who have an indication for OAC and to provide a framework to aid clinical decision-making in this area. PMID- 29588669 TI - Major Bleeding and Adverse Outcome following Percutaneous Coronary Intervention. AB - Advances in anti-thrombotic and anti-platelet therapies have improved outcomes in patients undergoing percutaneous coronary interventions (PCIs) through a reduction in ischaemic events, at the expense of peri-procedural bleeding complications. These may occur through either the access site through which the PCI was performed or through non-access-related sites. There are currently over 10 definitions of major bleeding events consisting of clinical events, changes in laboratory parameters and clinical outcomes, where different definitions will differentially influence the reported incidence of major bleeding events. Use of different major bleeding definitions has been shown to change the reported outcome of a number of therapeutic strategies in randomised controlled trials but as yet a universal bleeding definition has not gained widespread adoption in assessing the efficacy of such therapeutic interventions. Major bleeding complications are independently associated with adverse mortality and major adverse cardiovascular event (MACE) outcomes, irrespective of the definition of major bleeding used, with the worst outcomes associate with non-access-site related bleeds. We consider the mechanisms through which bleeding complications may affect longer-term outcomes and discuss bleeding avoidance strategies, including access site choice, pharmacological considerations and formal bleeding risk assessment to minimise such bleeding events. PMID- 29588670 TI - Contemporary Antiplatelet Strategies in the Treatment of STEMI using Primary Percutaneous Coronary Intervention. AB - Reperfusion therapy for patients presenting with an acute ST-segment elevation myocardial infarction (STEMI) involves primary percutaneous coronary intervention (PPCI) and concomitant oral antiplatelet and intravenous antithrombotic pharmacotherapy. There is a conflict between the desire to reduce the time between first medical contact and coronary re-canalisation and achieving effective platelet inhibition with oral antiplatelet agents. This review outlines the currently available antiplatelet treatments, and their place within the therapeutic timeline of a patient presenting with STEMI. Additionally, we focus on current challenges associated with effective antiplatelet treatment, including acute stent thrombosis (AST), the effect of morphine, platelet function assessment and concomitant anticoagulant therapy. PMID- 29588671 TI - Preventive Percutaneous Coronary Intervention in ST-elevation Myocardial Infarction - The Primacy of Randomised Trials. AB - Randomised trials show a benefit of preventive (non-infarct artery) percutaneous coronary intervention in patients with acute ST elevation myocardial infarction, but non-randomised studies do not. The evidence on each is quantified and assessed. The primacy of randomised trials reveals the danger of using non randomised studies that can, as in this case, give the wrong answer. PMID- 29588672 TI - Interventional Strategies in Thrombus Management for ST Elevation Myocardial Infarction. AB - The major limitation of modern primary percutaneous coronary intervention (PPCI) is distal embolisation of thrombus and microvascular obstruction. Microvascular flow, as measured by myocardial blush grade (MPG), predicts mortality after PPCI. Despite initial enthusiasm, current evidence does not support routine use of Intracoronary over intravenous glycoprotein 2b3a inhibitors during PPCI for ST elevation myocardial infarction (STEMI) to improve clinical outcomes. Manual thrombectomy (MT) improves MPG and reduces distal embolisation in meta-analyses of small trials. A single-centre trial (N=1071), the Thrombus aspiration during percutaneous coronary intervention in acute myocardial infarction study (TAPAS) trial showed a mortality reduction, which led guidelines to recommend routine manual aspiration. However, the largest randomised trial (Thrombus aspiration in ST-elevation myocardial infarction in Scandinavia [TASTE] trial, N=7021) showed no difference in mortality and only trends towards reduction in myocardial infarction (MI) and stent thrombosis. The TASTE trial had much lower than expected mortality and so was likely underpowered for modest but important treatment effects (20-30 % RRR). The Thrombectomy with PCI versus PCI alone in patients with STEMI undergoing primary PCI (TOTAL) trial (N=10,700) will determine if MT reduces important clinical events during PPCI. Thrombus management remains an important area of research in STEMI. PMID- 29588674 TI - Transcatheter Aortic Valve Replacement for Native Aortic Valve Regurgitation. AB - Transcatheter aortic valve replacement with either the balloon-expandable Edwards SAPIEN XT valve, or the self-expandable CoreValve prosthesis has become the established therapeutic modality for severe aortic valve stenosis in patients who are not deemed suitable for surgical intervention due to excessively high operative risk. Native aortic valve regurgitation, defined as primary aortic incompetence not associated with aortic stenosis or failed valve replacement, on the other hand, is still considered a relative contraindication for transcatheter aortic valve therapies, because of the absence of annular or leaflet calcification required for secure anchoring of the transcatheter heart valve. In addition, severe aortic regurgitation often coexists with aortic root or ascending aorta dilatation, the treatment of which mandates operative intervention. For these reasons, transcatheter aortic valve replacement has been only sporadically used to treat pure aortic incompetence, typically on a compassionate basis and in surgically inoperable patients. More recently, however, transcatheter aortic valve replacement for native aortic valve regurgitation has been trialled with newer-generation heart valves, with encouraging results, and new ancillary devices have emerged that are designed to stabilize the annulus-root complex. In this paper we review the clinical context, technical characteristics and outcomes associated with transcatheter treatment of native aortic valve regurgitation. PMID- 29588673 TI - The Role of Percutaneous Haemodynamic Support in High-risk Percutaneous Coronary Intervention and Cardiogenic Shock. AB - The experience and usage of percutaneous cardiac assist devices in cardiogenic shock as well as high-risk percutaneous coronary intervention have increased over the years. Nonetheless, there is still little evidence of clinical benefit of these devices other than immediate haemodynamic improvement. Despite the fact that these devices are used to treat a rather complex patient population, clinical testing remains important in order to evaluate their true impact on clinical outcome before being adopted into clinical practice. Therefore, this review shows an overview of the current experience and evidence of the available percutaneous cardiac assist devices. PMID- 29588675 TI - The Current Situation and the Future of Emergent Cardiac Surgery in TAVI. AB - Transcatheter aortic valve implantation (TAVI) has become a beneficial treatment for patients with aortic valve stenosis deemed at high or even prohibitive risk for open surgery. The risk for severe complications is low (ranging between 0.2 % and 1.0 %); nevertheless, in approximately 1 % of patients emergency cardiac surgery (ECS) is required during TAVI. Aortic injury, embolization of the TAVI prosthesis, and myocardial injury are among the most frequent complications necessitating ECS. Mortality rates of ECS during TAVI are high, ranging between 45 % and 67 %, owing to the comorbid and fragile health status of TAVI patients. Therefore, avoidance of complications appears to be of utmost importance to improve outcomes. This review analysis the current literature in terms of incidence, causes, and outcomes of ECS during TAVI. PMID- 29588676 TI - Indications for Surgery for Tricuspid Regurgitation. AB - Despite the fact that tricuspid regurgitation (TR) can result in significant symptoms, patients are rarely referred for isolated surgical repair, or replacement, and most surgeries are performed in the context of other planned cardiac surgery. In this article, we review the different causes of TR, the natural history of untreated severe TR, indications and timing for isolated TR surgery, indications for TR surgery performed at the time of left-sided valve surgery, and surgical approaches for correction of TR. PMID- 29588677 TI - Foreword. PMID- 29588678 TI - Is Hyperaemia Essential for Accurate Functional Assessment of Coronary Stenosis Severity? AB - Fractional flow reserve (FFR) requires the use of maximal hyperaemia as described in the original preclinical and clinical validation studies and subsequent practice changing randomized controlled trials. A perception that the need for hyperaemia (usually induced with adenosine) was one of the obstacles to more widespread adoption of FFR has led to interest in the use of resting non hyperaemic indices to assess the functional significance of coronary stenoses. We examine the current evidence base and conclude that resting indices agree with FFR in only 80 % of lesions when a binary cut-off is employed but closer to 90 % when hybrid strategies utilising both resting indices and FFR are utilised. It seems counter intuitive to sacrifice diagnostic accuracy when in most patients and healthcare systems the induction of hyperaemia with adenosine is safe and emminently affordable. PMID- 29588679 TI - Integrating Physiology into the DNA of Coronary Revascularisation - A Historical Perspective, Contemporary Review and Blueprint for the Future of Coronary Physiology. AB - The clinical and economic benefits of physiologically guided revascularisation have been demonstrated, yet its clinical adoption remains unacceptably low. Recently, new indices of stenosis severity have been introduced that aim to improve adoption by circumventing the limitations of existing indices. The most validated of these new indices is the instantaneous wave-free ratio (iFR). This review will describe the physiological basis of this index, how it avoids the problems of existing indices such as fractional flow reserve (FFR) and the clinical validation studies of iFR to date. We will then describe a novel use of iFR, which has the potential to transform the use of physiology in the catheter lab and finally integrate physiology into the DNA of coronary revascularisation. PMID- 29588680 TI - AXXESSTM Stent: Delivery Indications and Outcomes. AB - The successful treatment of coronary bifurcation lesions remains one of the challenges of interventional cardiology. The current consensus of the European Bifurcation Club based on published data advocates a provisional strategy, treating the main vessel (MV) with a single stent covering the side branch (SB), with bailout SB stenting as required. The success of this approach may be limited by failure to attain SB access after MV stenting but is preferred in most situations over routine SB plus MV stent techniques, which are associated with a significant increase in the rate of major adverse cardiac events. The AXXESS self expanding biolimus-eluting stent has been developed as a solution to these challenges within the coronary circulation and maintains provisional MV stent approach but with added assurance of maintained SB access. It has a unique conical structure that is positioned spanning the carina, with scaffold extending into the carina of both the MV and SB. The purpose of this article is to describe the indication, implantation technique and outcome data supporting the use of the AXXESS stent in the treatment of coronary bifurcation lesions. PMID- 29588681 TI - Vascular Access and Chronic Total Occlusion Angioplasty. AB - The hybrid algorithim approach, together with innovative new technologies, has lead to increased interest in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and increasing procedural success rates. Unlike non-CTO PCI, there is an increased rate of femoral access. When considering arterial access in CTO PCI, a balance is needed between anticipated procedural difficulty, planned CTO strategy and the desire to minimise the risk of vascular access-related complications. We review the evidence for best practice with respect to femoral puncture technique and also assess the technologies and techniques available to place larger inner diameter catheters into the radial artery. PMID- 29588682 TI - Avoiding Coronary Occlusion and Root Rupture in TAVI - The Role of Pre-procedural Imaging and Prosthesis Selection. AB - Coronary occlusion and rupture of the aortic root or annulus remain two major concerns of transcatheter aortic valve implantation technique. Despite their relatively low frequency they raised the interest of the scientific community as they carry an extremely poor prognosis. Prosthesis type and size selection is part of the patient selection process that allows the operator to prevent these complications. In this article, the techniques used either during pre-TAVI screening or during the procedure itself to avoid coronary occlusion and aortic rupture will be discussed. PMID- 29588683 TI - Permanent Pacemaker Implantation after TAVR - Predictors and Impact on Outcomes. AB - The number of patients undergoing transcatheter aortic valve replacement (TAVR) worldwide is increasing steadily. Atrioventricular conduction disturbances, with or without the need for permanent pacemaker (PPM) implantation, are one of the most common adverse events after TAVR. Among transcatheter heart valves (THV), rates of conduction abnormalities vary from less than 10 % to more than 50 %. Depending on the reported data referred to, historical data showed that up to one third of the patients required implantation of a PPM following TAVR. Although generally considered as a minor complication, PPM may have a profound impact on prognosis and quality of life after TAVR. Current data support the hypothesis that conduction abnormalities leading to pacemaker dependency result from mechanical compression of the conduction system by the prosthesis stent frame and individual predisposing conduction defects such as right bundle-branch block (RBBB). With several large randomised trials and registry studies having been published recently and second generation THV having been introduced, the debate about predictors for pacemaker implantation and their impact on outcome after TAVR is still ongoing. PMID- 29588684 TI - Balloon- or Self-Expandable TAVI: Clinical Equipoise? AB - Transcatheter aortic valve implantation (TAVI) has become an effective treatment option for patients with severe aortic stenosis and high surgical risk or contraindications for surgical aortic valve replacement. Most of the currently available prostheses employ either balloon-expandable or self-expandable designs. Presently, there is a paucity of data directly comparing these two widely used prosthesis types. Forthcoming trials will reveal whether newer designs of both technologies translate into fewer complications and better outcomes, with expansion of TAVI indications. This manuscript reviews features and clinical outcomes of balloon- and self-expanding prostheses, summarising current data from registries and trials. PMID- 29588685 TI - Real World Outcomes of Left Atrial Appendage Occlusion. AB - Percutaneous left atrial appendage occlusion (LAAO) is a device-based therapy for the prevention of stroke in patients with non-valvular atrial fibrillation (AF). Recently, the Watchman device (Boston Scientific, St Paul, MN, US) was approved in the US by the Food and Drug Administration (FDA) based on the results of two randomised clinical trials that evaluated LAAO in patients eligible for oral anticoagulation (OAC) therapy. However, in real-word clinical practice LAAO is typically offered to patients ineligible for OAC therapy, as they appear to have limited treatment options and consequently worse prognosis. Although LAAO has shown favourable clinical outcomes in OAC-ineligible patients in single or multicentre observational studies, these results need to be confirmed in randomised clinical trials. PMID- 29588686 TI - A Quick Guide to Paravalvular Leak Closure. AB - Paravalvular leak (PVL) is a seldomly covered aspect of structural heart disease. However, this is a condition that frequently presents after valvular replacement. This article will cover the diagnosising and treating PVL (i.e. imaging, access, and device selection). In addition, specific aspects of aortic and mitral PVL closure will be covered in this review. PMID- 29588687 TI - Foreword. PMID- 29588688 TI - Left Main Stem Percutaneous Coronary Intervention - Data and Ongoing Trials. AB - Left main stem (LMS) disease is associated with significant morbidity and mortality. Traditionally coronary artery bypass grafting (CABG) has been the gold standard for treatment of these lesions. However over the past decade, percutaneous coronary intervention (PCI) has assumed a more prominent role in the treatment of LMS disease. With the advent of newer drug-eluting stents (DES) with an improved risk factor profile, better intravascular imaging modalities and careful patient selection, the use of PCI in this cohort is expanding. We review the current data to support this and discuss the on-going trials that will hopefully shed more light into the management of this complex disease. PMID- 29588689 TI - Twelve Months Dual Antiplatelet Therapy after Drug-eluting Stents - Too Long, too Short or Just Right? AB - Dual Antiplatelet Therapy (DAPT) remains a cornerstone in the secondary prevention of coronary artery disease. Further, in contemporary practice, a period of DAPT is considered a mandatory requirement after intracoronary stents to prevent stent thrombosis (ST), a complication associated with heart attack and a mortality rate of up to 40 %. In current clinical practice, the default strategy in most centres is 12 months' DAPT followed by aspirin alone for life. However, the optimal duration of DAPT, particularly given the rapid iterative turnover of drug-eluting stents (DES) is the subject of discrepant evidence and clinical uncertainty. In particular, the 12-month regimen is based upon relatively weak evidence. A series of fairly small randomised trials, not powered to look specifically at ST as an endpoint, have recently indicated that there is no apparent disadvantage to shorter versus longer duration DAPT (including several trials of >12 months versus 12 months) when looking at various composite clinical endpoints. By contrast, the 9,961 patient DAPT trial, published in the New England Journal of Medicine at the end of 2014, demonstrated clinical outcome benefit, including a significantly lower rate of ST as a predefined primary endpoint, in DES patients randomised to 30 months' DAPT compared to stopping at 12 months. Here, the authors to assess the data, including the most recent meta analyses, in an attempt to answer the question: DAPT after DES...12 months, longer or shorter? PMID- 29588690 TI - Managing the Antithrombotic Therapy After Percutaneous Coronary Intervention in Patients on Oral Anticoagulation. AB - In patients on chronic oral anticoagulation (OAC) who are undergoing a percutaneous coronary intervention (PCI), dual antiplatelet therapy (aspirin and a P2Y12 inhibitor) is required. However, combining dual antiplatelet therapy with OAC increases the risk of bleeding. Newer and stronger P2Y12 inhibitors also add more complexity to the regimen, as these antiplatelet agents are currently recommended as standard treatment in patients with acute coronary syndromes (ACS). It remains unclear whether these ACS patients on chronic OAC undergoing PCI should be treated with these new P2Y12 inhibitors as part of the antiplatelet therapy. Another issue to address is that new non-vitamin K oral anticoagulants have emerged as possible alternatives for stroke prevention in patients with AF. Thus, the anticoagulated patient undergoing PCI faces a treatment dilemma. Based on a real-life case, we will discuss the optimal anticoagulant and antiplatelet treatment with a review of the literature. PMID- 29588691 TI - Spontaneous Coronary Artery Dissection. AB - Spontaneous coronary artery dissection (SCAD) is a non-traumatic and non iatrogenic separation of the coronary artery wall that is now recognised as an important cause of myocardial infarction, especially in younger women. SCAD can be elusive on coronary angiography and clinician familiarity with non pathognomonic angiographic SCAD variants and the use of intracoronary imaging will improve diagnosis. Conservative management and long-term cardiovascular follow-up are typically recommended. PMID- 29588692 TI - Review of Minimally Invasive Aortic Valve Surgery. AB - Minimally invasive aortic valve surgery (MIAVS) has been developed for the last 20 years. The improvements in techniques have permitted cardiac surgeons to perform aortic valve replacement safely and efficiently with minimally incisions. Patients have become older and have multiple comorbidities and this is expected to grow in number. Less-invasive procedures are known to reduce the number of complications, together with smaller incisions, less pain, less blood loss and reduced length of hospital stay. Selective preoperative planning with computed tomography is key to the pre-investigation stage. Hybrid and staged procedures with interventional cardiologists are part of the armamentarium and may be appealing for the present and near future. Despite the nature of demanding procedures and longer learning curve with increased cardiopulmonary bypass times, the outcomes are comparable with same quality as conventional open surgery. Patient recovery is the ultimate purpose of these approaches. PMID- 29588694 TI - Transcatheter Aortic Valve Implantation for Patients with Smaller Anatomy. AB - Transcatheter aortic valve implantation (TAVI) has reached relative maturity for the treatment of severe, symptomatic aortic stenosis (AS). TAVI for patients with smaller anatomy is a challenging procedure due to specific anatomical difficulty and complications including annulus rupture and vascular complications. Prevention of these complications, and the introduction of a newer-generation and lower-profile TAVI system, will encourage the prevalence of TAVI for patients with smaller anatomy. PMID- 29588693 TI - Computed Tomography for Structural Heart Disease and Interventions. AB - Transcatheter cardiac interventions are a fast evolving field. The past decade has seen the development of transcatheter aortic valve replacement, transcatheter mitral valve repair and replacement, septal defect closure devices and left atrial appendage closure devices for thromboprophylaxis. More than ever, medical imaging is taking a central role in the care of patients with structural heart disease. In this review article we outline the use of MSCT as a tool for diagnosis of structural heart interventions, as well as patient selection, pre procedural planning, device sizing and post-procedural assessment. We focus on procedures targeting the aortic valve, the mitral valve, the inter-atrial septum and the left atrial appendage. PMID- 29588695 TI - Patient-tailored Drug-eluting Stent Choice - A Solution for Patients with Diabetes: Proceedings of Two Satellite Symposia Held at EuroPCR in May 2015 in Paris. AB - Although second-generation drug-eluting stents (DES) have improved outcomes in percutaneous coronary interventions (PCIs), important unmet needs remain. Two symposia at EuroPCR 2015 focused on two challenging scenarios. First, patients with diabetes mellitus (DM) have generally inferior outcomes following PCI. The Cre8TM stent (manufactured by CID Spa, member of Alvimedica Group) has shown unique efficacy in subpopulations of patients with DM during clinical trials. A live case in a patient with diabetes illustrated the challenges of complex multivessel disease. Second, optimising stent selection towards devices that have demonstrated complete and early endothelialisation offers the potential to reduce the duration of dual antiplatelet therapy. The Cre8TM DES features a polymer-free platform and has been associated with low rates of in-stent thrombosis. PMID- 29588696 TI - Absorbable Polymer Technology - Viable Solutions for Unmet Needs in PCI: Proceedings of two satellite symposia held at EuroPCR, Paris in May 2015. AB - The use of drug-eluting stents (DES) has improved clinical outcomes in percutaneous coronary intervention procedures, but many challenges remain. In two symposia at EuroPCR 2015, the factors necessary to ensure successful chronic total occlusion (CTO) intervention were presented. Good preparation, sufficient operator experience and the correct approach are key to the success of CTO interventions. A live case demonstrated the challenges of these complex cases. Stent choice in CTO interventions is crucial; second-generation DES are associated with lower rates of restenosis and re-occlusion compared with first generation DES. The CoractoTM DES features unique structural properties and rapidly absorbable polymer, resulting in excellent conformability, efficacy and safety. PMID- 29588697 TI - Foreword. PMID- 29588698 TI - Editorial From the Coronary Section Editor. PMID- 29588699 TI - Choice of Intracoronary Imaging: When to use Intravascular Ultrasound or Optical Coherence Tomography. AB - Intracoronary imaging has the capability of accurately measuring vessel and stenosis dimensions, assessing vessel integrity, characterising lesion morphology and guiding optimal percutaneous coronary intervention (PCI). Coronary angiography used to detect and assess coronary stenosis severity has limitations. The 2D nature of fluoroscopic imaging provides lumen profile only and the assessment of coronary stenosis by visual estimation is subjective and prone to error. Performing PCI based on coronary angiography alone is inadequate for determining key metrics of the vessel such as dimension, extent of disease, and plaque distribution and composition. The advent of intracoronary imaging has offset the limitations of angiography and has shifted the paradigm to allow a detailed, objective appreciation of disease extent and morphology, vessel diameter, stent size and deployment and healing after PCI. It has become an essential tool in complex PCI, including rotational atherectomy, in follow-up of novel drug-eluting stent platforms and understanding the pathophysiology of stent failure after PCI (e.g. following stent thrombosis or in-stent restenosis). In this review we look at the two currently available and commonly used intracoronary imaging tools - intravascular ultrasound and optical coherence tomography - and the merits of each. PMID- 29588701 TI - Coronary Intervention with the Excimer Laser: Review of the Technology and Outcome Data. AB - Excimer laser coronary atherectomy (ELCA) is a long-established adjunctive therapy that can be applied during percutaneous coronary intervention (PCI). Technical aspects have evolved and there is an established safety and efficacy record across a number of clinical indications in contemporary interventional practice where complex lesions are routinely encountered. The role of ELCA during PCI for thrombus, non-crossable or non-expandable lesions, chronic occlusions and stent under-expansion are discussed in this review. The key advantage of ELCA over alternative atherectomy interventions is delivery on a standard 0.014-inch guidewire. Additionally, the technique can be mastered by any operator after a short period of training. The major limitation is presence of heavy calcification although when rotational atherectomy (RA) is required but cannot be applied due to inability to deliver the dedicated RotaWireTM (Boston Scientific), ELCA can create an upstream channel to permit RotaWire passage and complete the case with RA - the RASER technique. PMID- 29588700 TI - Fractional Flow Reserve: Does a Cut-off Value add Value? AB - Fractional flow reserve (FFR) has been shown to improve outcomes when used to guide percutaneous coronary intervention (PCI). There have been two proposed cut off points for FFR. The first was derived by comparing FFR against a series of non-invasive tests, with a value of <=0.75 shown to predict a positive ischaemia test. It was then shown in the DEFER study that a vessel FFR value of >=0.75 was associated with safe deferral of PCI. During the validation phase, a 'grey zone' for FFR values of between 0.76 and 0.80 was demonstrated, where a positive non invasive test may still occur, but sensitivity and specificity were sub-optimal. Clinical judgement was therefore advised for values in this range. The FAME studies then moved the FFR cut-off point to <=0.80, with a view to predicting outcomes. The <=0.80 cut-off point has been adopted into clinical practice guidelines, whereas the lower value of <=0.75 is no longer widely used. Here, the authors discuss the data underpinning these cut-off values and the practical implications for their use when using FFR guidance in PCI. PMID- 29588702 TI - Patient Selection and Procedural Considerations for Coronary Orbital Atherectomy System. AB - Despite advances in technology, percutaneous coronary intervention (PCI) of severely calcified coronary lesions remains challenging. Rotational atherectomy is one of the current therapeutic options to manage calcified lesions, but has a limited role in facilitating the dilation or stenting of lesions that cannot be crossed or expanded with other PCI techniques due to unfavourable clinical outcome in long-term follow-up. However the results of orbital atherectomy presented in the ORBIT I and ORBIT II trials were encouraging. In addition to these encouraging data, necessity for sufficient lesion preparation before implantation of bioresorbable scaffolds lead to resurgence in the use of atherectomy. This article summarises currently available publications on orbital atherectomy (Cardiovascular Systems Inc.) and compares them with rotational atherectomy. PMID- 29588703 TI - Primary Angioplasty For Patients in Cardiogenic Shock: Optimal Management. AB - Cardiogenic shock complicates approximately 5-10 % of all MI events and remains the most common cause of death among MI cases. Over the past few decades, the mortality rate associated with cardiogenic shock has decreased with the introduction of early revascularisation, although there are limited data for patients with triple-vessel disease and left main stem disease. In more recent years, there have been a number of advances in the mechanical circulatory support devices that can help improve the haemodynamics of patients in cardiogenic shock. Despite these advances, together with progress in the use of inotropes and vasopressors, cardiogenic shock remains associated with high morbidity and mortality rates. This review will outline the management of cardiogenic shock complicating acute MI with a smajor focus on revascularisation techniques and the use of mechanical circulatory support devices. PMID- 29588704 TI - Determining the Most Appropriate Mode of Coronary Artery Revascularisation in Patients With Diabetes. AB - Obstructive coronary artery disease is a common cause of morbidity and mortality among patients with diabetes mellitus (DM). Previous research has demonstrated that the clinical sequelae of coronary artery disease remains the most common cause of death in this population. As a result numerous observational studies and randomised clinical trials have evaluated the timing and mode of coronary artery revascularisation within this population. In this review, we survey the currently available data informing the indications and optimal method of coronary revascularisation for diabetic patients. PMID- 29588705 TI - The use of the Cre8 Stent in Patients With Diabetes Mellitus. AB - Despite improved clinical outcomes following the availability of second generation drug eluting stents (DES), percutaneous coronary intervention (PCI) is associated with worse clinical and angiographic outcomes among patients with diabetes mellitus (DM) than among non-diabetics. The Cre8TM Amphilimus-eluting DES is polymer-free, resulting in a reduced inflammatory response and lower risk of stent thrombosis. It showed equivalent efficacy and safety in diabetic and non diabetic populations, a unique finding among DES studies. These findings were confirmed in a real-world study called INVESTIG8. Another real-world study, pARTicip8, is ongoing. The RESERVOIR clinical trial recruited patients with diabetes mellitus and showed noninferiority of the Cre8 DES compared to an everolimus-eluting DES but showed a statistical superiority of Cre8 in diabetic patients with higher metabolic dysfunctions. The Cre8 DES is therefore a valuable option for this important patient population. PMID- 29588706 TI - Dual Antiplatelet Therapy After Drug-eluting Stent Implantation. AB - The current guidelines for percutaneous coronary intervention use recommend dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor after drug eluting stent (DES) implantation. The optimal duration of DAPT is however area of debate. Recent clinical trials and meta-analyses suggest that the choice of DAPT duration should be tailored individually, based on the balance between ischemic and bleeding risk carried by the patient. PMID- 29588707 TI - Impact of Mitral Regurgitation on Clinical Outcomes After Transcatheter Aortic Valve Implantation. AB - Severe aortic stenosis (AS) and mitral regurgitation (MR) are the two most common valvular lesions referred for surgical intervention in Europe and frequently co exist. In patients with both severe AS and significant MR referred for surgical aortic valve replacement (SAVR), a concomitant mitral valve intervention is typically performed if the MR is severe, despite the higher associated perioperative risk. The management of moderate MR among SAVR patients is controversial and depends on a number of factors including MR aetiology (i.e., organic versus functional MR), feasibility of repair and patient risk profile. Moderate or severe MR is present in up to one-third of patients undergoing transcatheter aortic valve implantation (TAVI), is mainly of functional aetiology and is typically left untreated. Although data are conflicting, a growing body of evidence suggests that significant MR exerts an adverse effect on both short- and long-term clinical outcomes after TAVI. Moderate or severe MR improves in just over half of patients following TAVI and recent data suggest MR is more likely to improve among patients receiving a balloon-expandable as compared with a self expandable transcatheter heart valve. PMID- 29588708 TI - Hybrid Imaging in the Catheter Laboratory: Real-time Fusion of Echocardiography and Fluoroscopy During Percutaneous Structural Heart Disease Interventions. AB - Percutaneous catheter-based techniques for the treatment of structural heart disease are becoming more complex, and current imaging techniques have limitations: while fluoroscopy gives poor visualisation of cardiac anatomical structures, echocardiography is limited in its ability to detect the position of catheters and devices. The EchoNavigator(r) (Philips) live image guidance tool is a novel system that integrates real-time echocardiography with fluoroscopic X-ray imaging, optimising the guidance and positioning of devices. Use of the EchoNavigator system facilitates improved understanding of anatomical structures while showing enhanced visualisation of catheter and device movements. Early clinical experience suggests that the technology is feasible and safe, and provides enhanced understanding of the relationship between soft tissue anatomy and catheter devices in structural heart disease. The use of the EchoNavigator system can improve the confidence of interventional cardiologists in the targeting and positioning of devices in percutaneous interventions in structural heart disease, and has the potential to reduce procedural time, reduce the dosage of contrast and radiation and increase safety in the performance of procedural steps. PMID- 29588709 TI - Interventional Therapies for Resistant Hypertension: A Brief Update. AB - Resistant hypertension remains a clinical challenge with few management options beyond maximisation of medications. Catheter- based renal artery denervation (RDN) was proposed in 2009 as a possible therapy for resistant hypertension and early feasibility trials caused excitement among cardiologists and antihypertensive specialists, showing remarkable and sustained blood pressure reductions. In 2014, enthusiasm for RDN dampened following the SYMPLICITY 3 trial results, which showed no statistically significant difference in blood pressure between the intervention and control arms. However, hope remains for the improved management of resistant hypertension; procedural understanding, technological advancements and alternative targets - such as baroreceptor activation therapy and arteriovenous shunts - may aid the identification of those patients for whom specific interventional therapies will be effective. PMID- 29588710 TI - Simulator Training in Interventional Cardiology. AB - Simulator training in interventional cardiology is becoming a central part of early career acquisition of technical and non-technical skills. Its use is now mandated by national training organisations. Haptic simulators, part-task trainers, immersive environments and simulated patients can provide benchmarked, reproducible and safe opportunities for trainees to develop without exposing patients to the learning curve. However, whilst enthusiasm persists and trainee centred evidence has been encouraging, simulation does not yet have a clear link to improved clinical outcomes. In this article we describe the range of simulation options, review the evidence for their efficacy in training and discuss the delivery of training in technical skills as well as human factor training and crisis resource management. We also review the future direction and barriers to the progression of simulation training. PMID- 29588711 TI - Foreword. PMID- 29588712 TI - Transradial Approach in Primary Percutaneous Coronary Intervention: Lessons from a High-volume Centre. AB - The transradial approach (TRA) is the recommended technique for percutaneous coronary intervention (PCI) in acute coronary syndrome, according to the European Society of Cardiology guidelines. There is a large body of evidence showing reduction in bleeding and mortality when the TRA is used. The TRA is also more convenient for patients, by allowing early mobilisation. Finally, by facilitating patient turnover and fast (re)transfer after the procedure, the TRA enables operators to meet the current recommendations of early invasive therapy in both ST and non-ST-elevation myocardial infarction. On the other hand, the TRA is technically more challenging than the transfemoral approach (TFA) and requires longer learning curve, which hinders its uptake by low-volume operators/centres. Nevertheless, in the hands of experienced high-volume operators, such as at Onze Lieve Vrouwe Gasthuis (OLVG) Amsterdam, the TRA achieves comparable procedural outcomes and favourable clinical results compared with the TFA, as it is in cases of primary PCI. PMID- 29588713 TI - Expert Opinion Percutaneous Coronary Intervention in Older People: Does Age Make a Difference? AB - As many people are living longer, much older patients are now commonly being seen in clinical practice. The management of coronary disease in this group presents formidable challenges. We review the epidemiology of coronary disease in this population and report on the burden of comorbidity, influence of frailty, problems with polypharmacy, interactions and compliance for the older patient. We discuss the management of stable and acute coronary syndromes, the specific anatomical challenges of the older coronary artery, the outcomes of the limited number of trials involving older patients, and review the guidelines available. PMID- 29588714 TI - Preventing Contrast-induced Renal Failure: A Guide. AB - Contrast-induced acute kidney injury (CI-AKI) is characterised by a rapid deterioration of renal function within a few days of parenteral administration of contrast media (CM) in the absence of alternative causes. CI-AKI is the most common form of iatrogenic kidney dysfunction with an estimated prevalence of 12 % in patients undergoing percutaneous coronary intervention. Although usually self resolving, in patients with pre-existing chronic kidney disease (CKD) or concomitant risk factors for renal damage, CI-AKI is associated with increased short-and long-term morbidity and mortality. Therefore, risk stratification based on clinical and peri-procedural characteristics is crucial in selecting patients at risk of CI-AKI who would benefit the most from implementation of preventive measures. PMID- 29588715 TI - Fractional Flow Reserve Measurement by Computed Tomography: An Alternative to the Stress Test. AB - Recent advances in computed tomographic technology have contributed towards improving coronary computed tomography angiography (CCTA) in determining the severity of coronary artery disease anatomically. Although the viability of CCTA has most often been confined to anatomical assessment, recent development has enabled evaluation of the haemodynamic significance of coronary artery disease. In light of this, CCTA-derived fractional flow reserve (FFRCT), a novel imaging modality, now permits the physiological assessment of coronary artery disease. To date, several studies have documented the diagnostic performance of FFRCT, and more trials are being performed that will further substantiate this technique. The present paper provides an overview and discussion of the available evidence for FFRCT in the clinical setting as well as potential future directions of FFRCT. PMID- 29588716 TI - Drug-coated Balloon-only Angioplasty for Native Coronary Disease Instead of Stents. AB - Coronary angioplasty has vastly improved both in technique and devices since the first angioplasty in 1977. Currently, stent implantation is used almost ubiquitously, despite being developed originally to treat vessel threatening dissections. Newer concepts including absorbable polymers or fully bioabsorbable scaffolds are constantly being developed. However, we find the concept of no permanent implant whilst still delivering a chemotherapeutic drug to reduce restenosis very attractive given the long term implications of a metallic stent, which include restenosis, late thrombosis and neo-atheroma formation. The use of a drug-coated balloon-only approach to de novo angioplasty will avoid the late thrombotic problems whilst also reducing early restenosis, simplifying the procedure and reducing the dual antiplatelet duration to 1 month. We review the current literature and highlight our practice with regard to use of drug-coated balloons in treatment of de novo coronary artery disease. PMID- 29588717 TI - The FAME Trials: Impact on Clinical Decision Making. AB - Careful and stepwise evaluation of the fractional flow reserve (FFR) index has been performed over the years, culminating in the landmark Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) and Fractional Flow Reserve-Guided Percutaneous Coronary Intervention Plus Optimal Medical Treatment Versus Optimal Medical Treatment Alone in Patients with Stable Coronary Artery Disease (FAME II) trials. Findings from these studies demonstrated unequivocally the overall inadequacy of angiography versus FFR to correctly assess stenosis severity. Thus, proof of concept and clinical applicability was established beyond debate and will be discussed here. PMID- 29588718 TI - Emerging Technology Update Intravascular Photoacoustic Imaging of Vulnerable Atherosclerotic Plaque. AB - The identification of vulnerable atherosclerotic plaques in the coronary arteries is emerging as an important tool for guiding atherosclerosis diagnosis and interventions. Assessment of plaque vulnerability requires knowledge of both the structure and composition of the plaque. Intravascular photoacoustic (IVPA) imaging is able to show the morphology and composition of atherosclerotic plaque. With imminent improvements in IVPA imaging, it is becoming possible to assess human coronary artery disease in vivo. Although some challenges remain, IVPA imaging is on its way to being a powerful tool for visualising coronary atherosclerotic features that have been specifically associated with plaque vulnerability and clinical syndromes, and thus such imaging might become valuable for clinical risk assessment in the catheterisation laboratory. PMID- 29588719 TI - The Need For Dedicated Bifurcation Stents: A Critical Analysis. AB - There is growing evidence that optimally performed two-stent techniques may provide similar or better results compared with the simple techniques for bifurcation lesions, with an observed trend towards improvements in clinical and/or angiographic outcomes with a two-stent strategy. Yet, provisional stenting remains the treatment of choice. Here, the author discusses the evidence - and controversies - concerning when and how to use complex techniques. PMID- 29588720 TI - Non-coronary Interventions: An Introduction to Peripheral Arterial Interventions. AB - With an ageing population, the burden of peripheral artery diseases (PADs) is increasing. The treatment of these diseases has largely been performed by interventional radiologists, vascular surgeons and interventional cardiologists. Due to the strong relationship between PAD and overall cardiovascular morbidity and mortality, cardiologists need to play a greater role in the management of PAD. The physician who cares for the patient with peripheral vascular disease should have a broad understanding of atherosclerotic disease involving all vascular beds. Endovascular interventions play a major role in relieving symptoms and reducing morbidity related to PAD, but long-term optimal medical treatment is an essential determinant of prognosis. This paper reviews current endovascular/percutaneous interventions for PAD. PMID- 29588722 TI - Foreword. PMID- 29588721 TI - The Changing Paradigm in the Treatment of Structural Heart Disease and the Need for the Interventional Imaging Specialist. AB - Percutaneous interventions in structural heart diseases are emerging rapidly. The variety of novel percutaneous treatment approaches and the increasing complexity of interventional procedures are associated with new challenges and demands on the imaging specialist. Standard catheterisation laboratory imaging modalities such as fluoroscopy and contrast ventriculography provide inadequate visualisation of the soft tissue or three-dimensional delineation of the heart. Consequently, additional advanced imaging technology is needed to diagnose and precisely identify structural heart diseases, to properly select patients for specific interventions and to support fluoroscopy in guiding procedures. As imaging expertise constitutes a key factor in the decision-making process and in the management of patients with structural heart disease, the sub-speciality of interventional imaging will likely develop out of an increased need for high quality imaging. PMID- 29588723 TI - Use of Intravascular Ultrasound Imaging in Percutaneous Coronary Intervention to Treat Left Main Coronary Artery Disease. AB - Due to its potential prognostic implications and technical complexity, revascularisation of left main coronary artery (LMCA) disease requires careful consideration. Since publication of the results of the SYNTAX study, and more recently the EXCEL and NOBLE trials, there has been particular interest in percutaneous revascularisation of the LMCA. It is becoming clear that percutaneous revascularisation of LMCA disease requires appropriate lesion preparation and carefully optimised stenting in order to offer patients a treatment option as effective as coronary artery bypass grafting. For this reason intravascular imaging, and especially intravascular ultrasound, is becoming a key procedural step in LMCA percutaneous coronary intervention. In the current review paper we analyse the role of intravascular imaging with intravascular ultrasound in LMCA percutaneous coronary intervention, focusing on the main applications in this context from lesion assessment to stent sizing and optimisation. PMID- 29588724 TI - PCI in Patients with Diabetes: Role of the Cre8 Drug-eluting Stent. AB - Patients with diabetes have poor outcomes compared to the general patient population when undergoing percutaneous coronary intervention. The Cre8TM (Alvimedica) drug-eluting stent (DES) has unique features that may improve clinical outcomes in patients with diabetes. These include abluminal reservoir technology, a proprietary polymer-free drug-release system consisting of reservoirs on the stent's outer surface that control and direct drug release exclusively towards the vessel wall, and the AmphilimusTM formulation, which enables enhanced drug tissue permeation, utilising fatty acid transport pathways. This is particularly advantageous in diabetic patients, since increased uptake of fatty acid occurs in diabetic cells. Furthermore, mTOR inhibitors (-limus drugs), which are utilised in DESs, are relatively ineffective in diabetic cells. Clinical efficacy and safety of the Cre8TM in patients with diabetes has been demonstrated in a number of clinical trials and real-world studies, and further studies are on-going. PMID- 29588725 TI - Expert Opinion: Transradial Coronary Artery Procedures: Tips for Success. AB - Historically, the majority of coronary procedures have been performed via the femoral artery. However, since the inception of the transradial approach, a number of studies have confirmed that this technique is associated with a significant reduction in vascular complications, equivalent procedure times and radiation exposure to femoral procedures, the ability to perform complex coronary interventions, early ambulation and patient preference. Over the last decade, this has led to an exponential rise in the use of the transradial access site, with several potential technical challenges becoming increasingly recognised. However, with greater experience and technological advancement these potential obstacles may be overcome. The following review highlights the potential challenges and suggests several tips to assist transradial operators with recognising and overcoming these challenges. PMID- 29588726 TI - Managing Stroke During Transcatheter Aortic Valve Replacement. AB - Transcatheter aortic valve replacement (TAVR) has become the default treatment option for high-risk patients with aortic stenosis and an alternative to surgical aortic valve replacement in intermediate-risk patients. There are, however, concerns regarding strokes during TAVR. Reported stroke rates vary strongly depending on the type of study, stroke definition, cohort and study period. Furthermore, stroke after TAVR occurs in three distinct phases: 1) early high risk, directly procedure related; 2) elevated risk interval between day 2 and day 30; 3) late hazard interval. Each of these phases is caused by the different aetiologies of stroke. This review summarises the different aetiologies and potential strategies for managing stroke during TAVR. PMID- 29588727 TI - Use of Embolic Protection Devices in Peripheral Interventions. AB - The use of embolic protection devices (EPDs) when treating coronary saphenous vein bypass grafts, performing carotid arterial stenting and treating acute coronary syndromes is well accepted. We will review currently available devices and approaches to reduce distal embolisation, first discussing their uses in carotid interventions and then in vertebral and peripheral vascular interventions. PMID- 29588728 TI - Need for Embolic Protection During Transcatheter Aortic Valve Implantation: An Interventionalist's Perspective on Histopathology Findings. AB - Transcatheter aortic valve implantation (TAVI) is a less invasive aortic valve replacement technique and is indicated for patients with symptomatic severe aortic stenosis and a high operative risk. Cerebral embolisation seems inherent to TAVI, as illustrated by the consistent appearance of new brain lesions on post procedural MRI studies. Embolic protection devices may capture or deflect embolised material en route to the brain and thus reduce TAVI-related brain injury. Histopathology studies of captured debris revealed a diverse aetiology including recent or organised thrombotic material, tissue originating from the aortic valve, atherosclerotic plaques or myocardium and foreign body components. In this overview we provide a perspective on current evidence and implications for embolic protection devices in the dynamic TAVI field. PMID- 29588729 TI - Optimising the Haemodynamics of Aortic Valve-in-valve Procedures. AB - Bioprosthetic surgical valves are increasingly implanted during cardiac surgery, instead of mechanical valves. These tissue valves are associated with limited durability and as a result transcatheter valve-in-valve procedures are performed to treat failed bioprostheses. A relatively common adverse event of aortic valve in-valve procedures is residual stenosis. Larger surgical valve size, supra annular transcatheter heart valve type, as well as higher transcatheter heart valve implantation depth, have all been shown to reduce the incidence of elevated post-procedural gradients. With greater understanding of technical considerations and surgical planning, valve-in-valve procedures could be more effective and eventually may become the standard of care for our increasingly ageing and comorbid population with failed surgical bioprostheses. PMID- 29588730 TI - A Glimpse into the Future: In 2020, Which Patients will Undergo TAVI or SAVR? AB - Transcatheter aortic valve implantation (TAVI) has evolved into a safe and effective procedure to treat symptomatic patients with severe aortic stenosis (AS), with predictable and reproducible results. Rates of important complications such as vascular complications, strokes and paravalvular leaks are lower than ever, because of improved patient selection, systematic use of multidector computer tomography, increasing operator experience and device iteration. Accumulating data suggest that transfemoral TAVI with newer generation transcatheter heart valves and delivery systems is superior to conventional surgical aortic valve replacement among intermediate- and high-risk patients with severe symptomatic AS with regard to all-cause mortality and stroke. One can anticipate that by 2020, the majority of patients with severe symptomatic AS will undergo TAVI as first line therapy, regardless of surgical risk. PMID- 29588731 TI - Management of Tricuspid Regurgitation: The Role of Transcatheter Therapies. AB - Surgical treatment is the gold standard treatment of functional tricuspid regurgitation (FTR) but this carries high risks of morbidity and mortality. Percutaneous procedures are an attractive alternative to surgery for selected patients deemed to be high-risk surgical candidates. A number of tricuspid transcatheter devices have been developed to treat FTR, but at present, evidence of their efficacy and safety is scarce. Preliminary data have shown promising results, but ongoing and future studies will provide a clearer picture of the benefits of these new techniques. PMID- 29588732 TI - Aortic Dissection: Novel Surgical Hybrid Procedures. AB - The management of patients with aortic dissection is challenging and its treatment is an area of development and innovation. Conventional surgical techniques are associated with significant risks in terms of mortality and morbidity in such high-risk patients. As a result of cumulative advances in technology, classical surgical techniques have been improved and enhanced by the newer endovascular approaches, leading to novel surgical hybrid procedures. Impressive early results have been seen with frozen elephant techniques, revascularisation of the supra-aortic branches and branched/fenestrated thoracic endovascular aortic repair-alone procedures. This review describes the techniques involved in the latest hybrid procedures for aortic dissection and their outcomes. PMID- 29588733 TI - Foreword. PMID- 29588734 TI - Expert Opinion: Optimising Stent Deployment in Contemporary Practice: The Role of Intracoronary Imaging and Non-compliant Balloons. AB - Final stent dimensions remain an important predictor of restenosis, target vessel revascularisation (TVR) and subacute stent thrombosis (ST), even in the drug eluting stent (DES) era. Stent balloons are usually semi-compliant and thus even high-pressure inflation may not achieve uniform or optimal stent expansion. Post dilatation with non-compliant (NC) balloons after stent deployment has been shown to enhance stent expansion and could reduce TVR and ST. Based on supporting evidence and in the absence of large prospective randomised outcome-based trials, post-dilatation with an NC balloon to achieve optimal stent expansion and maximal luminal area is a logical technical recommendation, particularly in complex lesion subsets. PMID- 29588735 TI - Current State of the Art in Approaches to Saphenous Vein Graft Interventions. AB - Saphenous vein grafts (SVGs), used during coronary artery bypass graft surgery for severe coronary artery disease, are prone to degeneration and occlusion, leading to poor long-term patency compared with arterial grafts. Interventions used to treat SVG disease are susceptible to high rates of periprocedural MI and no-reflow. To minimise complications seen with these interventions, proper stents, embolic protection devices (EPDs) and pharmacological selection are crucial. Regarding stent selection, evidence has demonstrated superiority of drug eluting stents over bare-metal stents in SVG intervention. The ACCF/AHA/SCA American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines and the Society for Cardiovascular Angiography and Interventions guidelines recommend the use of EPDs during SVG intervention to decrease the risk of periprocedural MI, distal embolisation and no-reflow. The optimal pharmacological treatment for slow or no-reflow remains unclear, but various vasodilators show promise. PMID- 29588736 TI - Unprotected Left Main Coronary Artery Disease: Management in the Post NOBLE and EXCEL Era. AB - The optimal management of unprotected left main coronary artery (ULMCA) disease is currently a debated topic. Percutaneous coronary intervention (PCI) has seen an increased adoption for the management of ULMCA disease after numerous small scale randomised trials and cohort studies showed equipoise with coronary artery bypass grafting (CABG) for low complexity lesions. The recently published NOBLE and EXCEL trials are two of the largest international randomised clinical trials comparing PCI and CABG in patients with ULMCA disease. In lieu of all the available evidence, PCI appears to be equivalent to CABG in regard to mortality in patients with ULMCA disease. In non-diabetic patients with low complexity coronary disease (SYNTAX score <=32), PCI appears to be a reasonable alternative to CABG, especially for ostial and midshaft left main coronary lesions. CABG is preferable in the presence of diabetes, multivessel coronary disease in addition to ULMCA or complex coronary lesions (SYNTAX score >33) including distal left main lesions. PMID- 29588737 TI - Performing and Interpreting Fractional Flow Reserve Measurements in Clinical Practice: An Expert Consensus Document. AB - Fractional flow reserve (FFR) measurements can determine the haemodynamic relevance of coronary artery stenoses. Current guidelines recommend their use in lesions in the absence of non-invasive proof of ischaemia. The prognostic impact of FFR has been evaluated in randomised trials, and it has been shown that revascularisation can be safely deferred if FFR is >0.80, while revascularisation of stenoses with FFR values <=0.80 results in significantly lower event rates compared to medical treatment. Left main stenoses, aorto-ostial lesions, as well as patients with left ventricular hypertrophy and severely-impaired ejection fraction, have been excluded from large, randomised trials. While FFR measurements are relatively straightforward to perform, uncertainty about procedural logistics, as well as data acquisition and interpretation in specific situations, could explain why they are not widely used in clinical practice. We summarise the clinical data in support of FFR measurements, and provide recommendations for performing and interpreting the procedure. PMID- 29588738 TI - The Proximal Optimisation Technique for Intervention of Coronary Bifurcations. AB - The proximal optimisation technique (POT) has been proposed as a strategy to improve the results of stent scaffolding of bifurcation lesions. It is a straightforward technique whereby a short, appropriately-sized balloon is inflated in the main vessel just proximal to the carina. The technique has several advantages: it reduces the risk of side branch compromise related to shifting of the carina, it improves stent apposition in the proximal main vessel, and it facilitates side branch access after main vessel stent implantation. When treating bifurcations, final kissing balloon dilation (KBD) has traditionally been used routinely to optimise angiographic results. However, recent clinical data have questioned this philosophy and bench models have demonstrated several shortcomings of KBD. Instead, the optimal strategy may centre on performing POT, followed by side branch dilation, and completed with a final (re)-POT. The following review article describes how to perform POT and presents the evidence to support its' routine use. PMID- 29588740 TI - Expert Opinion Will PARTNER 2 Change My Practice? AB - Transcatheter aortic valve implantation (TAVI) has become an established and increasingly-used technique to treat patients with severe aortic valve stenosis (AS) over the past decade. The clinical outcomes obtained with TAVI have been found to be equivalent to surgical aortic valve replacement (SAVR) in patients with a high-risk profile. Following the Placement of Aortic Transcatheter Valves (PARTNER) 1 trial, which demonstrated the utility of TAVI in inoperable and high risk groups, the PARTNER 2 trial was implemented. PARTNER 2 reflects the current TAVI practice in Europe, confirms that transfemoral access is related to superior outcomes compared to SAVR in a selected population and demonstrates improved results with new-generation devices. PMID- 29588739 TI - Predilatation Prior to Transcatheter Aortic Valve Implantation: Is it Still a Prerequisite? AB - Predilatation has been historically considered a mandatory step before transcatheter aortic valve implantation (TAVI) since it facilitates valve crossing and prosthesis delivery, ensures optimal valve expansion and improves hemodynamic stability during valve deployment. However, as a result of procedural evolution over time, direct TAVI (without pre-implantation balloon aortic valvuloplasty) has emerged as an interesting option to simplify the procedure and to avoid potential valvuloplasty-related complications. Several real-world retrospective studies and one small randomised study have shown that direct TAVI (with both self-expanding and balloon-expandable prostheses) is feasible, safe and associated with outcomes similar to standard TAVI with pre-implantation balloon aortic valvuloplasty. In the absence of high-quality, robust evidence, the current review aims to discuss the advantages and disadvantages of omitting predilatation prior to TAVI. PMID- 29588741 TI - Safety and Efficacy of Protected Cardiac Intervention: Clinical Evidence for Sentinel Cerebral Embolic Protection. AB - Stroke is a well-documented potential risk of structural cardiac interventions. As a result of the far-reaching burden of stroke on patients, caregivers and the healthcare system, new medical interventions and therapies are being developed to help mitigate this risk. One such intervention is the recently FDA-cleared SentinelTM Cerebral Protection System (Sentinel; Claret Medical, Santa Rosa, CA, USA) designed to capture and remove debris dislodged during transcatheter aortic valve replacement procedures. In the SENTINEL IDE Study, and in a more recent all comers trial, Sentinel significantly reduced periprocedural strokes by 63 and 70 % respectively. In this paper, we review the growing body of evidence supporting the use of Sentinel in transcatheter aortic valve replacement and other endovascular procedures. PMID- 29588742 TI - Expert Opinion: Guidelines for the Management of Patients with Aortic Stenosis Undergoing Non-cardiac Surgery: Out of Date and Overly Prescriptive. AB - Patients with severe aortic stenosis who require non-cardiac surgery present a difficult clinical problem. The most recent clinical practice guidelines from the American College of Cardiology/American Heart Association and the European Society of Cardiology for the perioperative cardiovascular assessment and management of patients undergoing noncardiac surgery were both published in 2014. These guidelines are reviewed in the light of recently published randomised controlled trial data regarding the efficacy of transcatheter aortic valve implantation to treat aortic stenosis. PMID- 29588743 TI - Foreword. PMID- 29588745 TI - Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention for Unprotected Left Main Disease - A Review. AB - There have been over a dozen studies in the drug-eluting stent era comparing the effectiveness of percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery for the treatment of unprotected left main disease. These studies have been both randomised and observational in nature. While both methodologies provide important insights, careful consideration of their respective strengths and limitations is imperative in generalising their findings. PMID- 29588744 TI - Acute Coronary Syndrome in Pre- and Post-partum Women - A Review. AB - Acute coronary syndrome (ACS) during pregnancy and the post-partum period are weighed by a high mortality rate for the mother and foetus. They should be considered as multifactorial diseases with a special role for sexual hormones. In this setting, ACS is mostly related to an early atherosclerotic disease, even if other conditions are responsible. Indeed, an important part is due to spontaneous coronary artery dissection, more common during delivery and the post-partum period. In the remaining situation, an isolated intracoronary thrombus or a normal angiographic pattern can be found at angiography. Pathophysiology is still uncertain with different hypothetical mechanisms. Prompt diagnosis of ACS and aetiology are essential for an optimal therapeutic strategy. Difficulties in treatment management is a matter for debate, especially in pre-partum women. In the last two decades improvements of diagnostic tools, coronary angiography and subsequent percutaneous treatment have changed the natural history of this rare condition. PMID- 29588746 TI - Dedicated Bifurcation Drug-eluting Stent BiOSS(r) - A Novel Device for Coronary Bifurcation Treatment. AB - The Bifurcation Optimisation Stent System (BiOSS(r)) (Balton(r), Poland) is a coronary, dedicated bifurcation, balloon-expandable stent made of 316 litre stainless steel tube with strut thickness of 120 micrometre (um). It is covered with a mixture of a biodegradable polymer and an antiproliferative substance - paclitaxel (BiOSS Expert version) or sirolimus (BiOSS Lim version). The stent consists of two parts (the proximal with a larger diameter in relation to the distal one) connected with two connection struts (average 1.2 mm in length) at the step-up middle zone. The stent is crimped on a bottle-shaped semi-complaint balloon (Bottle(r), Balton, Poland). Our intravascular ultrasound (IVUS) study revealed that the construction of the BiOSS stent assures an easy access to the side branch and is comparable to the classic stent lumen enlargement with less injury to the area adjacent to the most sensitive part of the bifurcation. A total number of 65 lesions in 63 consecutive patients were enrolled in the First In-Man (FIM) registry for BiOSS Expert, where we achieved a 100 % device success rate. The long-term clinical results were satisfactory and closely related to the high-risk profile of the treated population. Our data demonstrated that simple and fast bifurcation treatment with a single dedicated bifurcation paclitaxel eluting stent (BiOSS Expert) is feasible and highly successful. Based on the data collected in animal experiments and preliminary data in humans with BiOSS Lim, releasing sirolimus from the surface of the biodegradable coating, one may presume that this version will provide even better clinical results compared with the paclitaxel one.

AB - This paper provides an overview of radiation exposure and its associated risks in the cardiac catheterisation laboratory (cath lab), as well as strategies to minimise radiation exposure for operators, cath lab staff and patients. The benefits of using a mobile 2 mm lead equivalent radiation shield (PISAX) and adoption of an automated contrast injection system (the ACIST CVi(r) Contrast Delivery System) are discussed, and the potential advantages of their combination are reviewed. PMID- 29588747 TI - Invasive Imaging of Bioresorbable Coronary Scaffolds - A Review. AB - Various fully bioresorbable stents (BRS) have been recently developed, allowing for temporary scaffolding of the vessel wall. The potentially unique advantage of BRS to temporary scaffold the vessel could reduce the risk of adverse clinical outcomes caused by acute vessel geometry changes, late malapposition, jailed side branches or inflexibility of permanent stents. The design of BRS is, however, not similar for all stents, resulting in differences in degradation and behaviour. To assess the performance of BRS, the effect of degradation and behaviour on the vessel wall should be accurately evaluated. Intracoronary imaging techniques such as intravascular ultrasound (IVUS), optical coherence tomography (OCT) and near infrared spectroscopy (NIRS) allow for detailed longitudinal evaluation of the stent and the vessel wall and might therefore aid in improving design and behaviour of BRS. PMID- 29588749 TI - Coronary Chronic Total Occlusion Recanalisation - Current Techniques and Approaches. AB - Coronary chronic total occlusions (CTOs) are among the most challenging coronary artery lesions to treat percutaneously. In the last decade, great strides have been made to develop techniques to improve success rates. While success rates among high-volume operators are >90 %, non-CTO operators still continue to struggle with this lesion subset. Thus, efforts have been made to develop algorithms to help operators achieve successful recanalisation consistently and improve patient outcomes. The North American Total Occlusion (NATO) algorithm emphasises dual coronary injection using two guide catheters, which allows for switching from an antegrade to retrograde approach or vice versa should the initial strategy fail - the so-called 'hybrid' approach. Special attention is paid to four angiographic characteristics: 1) location of the proximal cap, 2) lesion length, 3) presence and suitability of collateral vessels for retrograde crossing and 4) location and quality of target vessel distal cap. The ultimate goal of this algorithm is to provide a strategy to achieve successful CTO revascularisation while using the least amount of fluoroscopy, contrast and equipment possible. PMID- 29588750 TI - Double Chronic Total Occlusion Recanalisation with Antegrade and Retrograde Techniques and the Use of a Novel Drug-eluting Stent with Biodegradable Polymer. AB - Percutaneous recanalisation of coronary chronic total occlusions (CTOs) has proved an efficient and safe treatment option with steadily ascending success rates, especially since the advent and constant refinement of the retrograde approach. Uptake remains low, even though experienced operators have in the last five years reached an unprecedented maturity level, producing success rates in the range of 90 %, clearly comparable to non-occlusive coronary artery disease treatment. Antegrade and retrograde techniques are currently considered complementary components of a CTO procedure, rather than discrete treatment strategies. We report on the case of a successful CTO recanalisation procedure on a young patient with two chronically occluded coronary arteries and a large ischaemic burden. Both CTOs were addressed in the same session employing a range of dedicated CTO recanalisation techniques, without compromising on safety issues related to contrast dye consumption and radiation exposure. A novel drug-eluting stent (DES) with biodegradable polymer was used to treat the lesions. PMID- 29588751 TI - Carotid Artery Stenting - Strategies to Improve Procedural Performance and Reduce the Learning Curve. AB - Carotid artery stenting (CAS) remains an appealing intervention to reduce the stroke risk because of its minimal invasive nature. Nevertheless, landmark randomised controlled trials have not been able to resolve the controversies surrounding this complex procedure as the peri-operative stroke risk in a non selected patient population still seems to be higher after CAS in comparison to carotid endarterectomy. What is more, these trials have highlighted that patient outcome after CAS is influenced by patient- and operator-dependant factors. The CAS procedure exhibits a definitive learning curve resulting in higher complication rates if the procedure is performed by inexperienced interventionists or in low-volume centres. This article will outline strategies to improve the performance of physicians carrying out the CAS procedure by means of proficiency-based training, credentialing, virtual reality rehearsal and optimal patient selection. PMID- 29588752 TI - Endovascular Abdominal Aortic Aneurysm Repair - Patient Selection and Long-term Outcome Expectations - Current Challenges in 2013. AB - Endografts for repair of abdominal aortic aneurysm were first reported in the late 1980s and commercially available grafts were developed rapidly during the 1990s. This prompted a head-to-head comparison of the new, less invasive, endovascular technology with the existing gold standard of open repair. The first and largest randomised trial of open versus endovascular repair for large aneurysms started in the UK in 1999. Other trials comparing open and endovascular repair followed in the Netherlands, France and the US. Only the UK trial has reported long-term follow-up to 10 years. This has shown no statistically significant difference in long-term survival after open or endovascular repair. Aneurysm-related mortality curves converged at six years, which is described as endovascular aortic repair (EVAR) 'catch up' on open repair. It appears that this convergence is probably largely attributable to secondary sac rupture after endovascular repair, which is fatal in about two-thirds of cases. At this point, we have reached a crossroads and only longer-term follow-up data can provide the vital answer to the outcome of endovascular repair in the long run. This article gives a brief overview of the development and the current evidence of endovascular aortic repair and discusses the most important factors that are leading the way to the future of this technology. PMID- 29588753 TI - Foreword. PMID- 29588754 TI - Evidence-based Management of Cardiogenic Shock After Acute Myocardial Infarction. AB - Guidelines for evidence-based management of patients with cardiogenic shock after acute myocardial infarction focuses on early revascularisation of the occluded coronary artery as well as on support of cardiac failure and improvement of impaired organ perfusion. Also of great importance is effective treatment of shock complications, especially acute respiratory failure and other forms of multiple organ dysfunction syndrome (MODS). Cardiovascular therapy has to be accompanied by best general intensive care of these critically ill patients with high mortality. Most lives can be saved by early revascularisation, and this class I recommendation has a high level of evidence. So far, most of the other guideline recommendations are of low evidence level, in most cases based on expert opinions. Recently, the Intra-aortic Balloon Pump in Cardiogenic Shock II (IABP SHOCK II) trial with 600 patients has shown that adjunctive IABP therapy - for long a class I recommendation - does not reduce 30-day and six-month motality. PMID- 29588755 TI - The Role of the Transradial Approach for Complex Coronary Interventions in Patients with Acute Coronary Syndrome. AB - Despite advances in antithrombotic and antiplatelet therapy, bleeding complications remain an important cause of morbidity and mortality in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). A significant proportion of such bleedings are related to the access site, and adoption of transradial access (TRA) may reduce these complications. In patients with ST-segment elevation myocardial infarction (STEMI), TRA reduced cardiac mortality in comparison with the femoral approach (TFA). High-risk patients such as women, obese patients and elderly subjects who are at increased risk for vascular complications and bleeding, might particularly benefit from the TRA. However, specific radial expertise providing procedural time and a success rate comparable to those with the TFA are strongly recommended before using this technique in the emergency setting. PMID- 29588756 TI - The Role of Bioresorbable Scaffolds in Meeting the Challenges of Bifurcations. AB - Side branches are frequently related to periprocedural complications. Considering any side branches >1 millimetres (mm), side branch occlusion or reduced flow may occur in approximately 10 % of interventional procedures. First data indicate that bioresorbable vascular scaffolds (BVS) behave similar compared with modern drug-eluting stents (DES) with regard to compromising or occluding sizeable side branches. Although technically more demanding compared with modern DES, it appears to be feasible to dilate side branches after crossing BVS cells. Preliminary data suggest at least balloon diameters up to 2.5 mm can be used, but safety remains unclear. Instead of kissing balloon dilatation, rather sequential balloon dilatation should be employed. Anecdotic evidence suggests BVS can be used even in relatively complex coronary anatomy, e.g. bifurcations distal to chronic total occlusion. Certainly more data are needed. As of today, BVS offer promise not only for the treatment of simple coronary lesions but also bifurcations. Given successful side branch protection, they might allow for restoring the native coronary anatomy in the sense of restitutio ad integrum. PMID- 29588757 TI - How to Select the Most Appropriate Patient and Lesion to be Treated with a Coronary Bioresorbable Vascular Scaffold. AB - Bioresorbable vascular scaffolds (BVS) are an exciting novel treatment for coronary artery disease (CAD) as their eventual resorption renders the artery free from a permanent metallic cage. Clinical trials regarding these novel devices have demonstrated promising results, although their use in this context has largely been restricted to simple lesions. More recently, BVS use has expanded to patients with more complex lesions including those with long diffuse disease, and results from several registries are awaited with regard to their efficacy in 'real-world' patients. Although any patient who requires percutaneous treatment for CAD could benefit from BVS implantation, there are certain cohorts of patients and lesions in whom BVS could be of particular benefit. In this review, we attempt to identify which patient and lesion cohort is most suitable for treatment with these novel devices. PMID- 29588758 TI - Personal Experience with Bioresorbable Scaffolds in Bifurcations. AB - Bioresorbable scaffolds represent a promising new technology in the field of percutaneous coronary interventions. The concept of the eventual resorption of the scaffold pertains to multiple theoretical advantages that may hold true particularly in bifurcation lesions - no permanent caging of the coronary artery, avoidance of acquired device malapposition and delayed hypersensitivity reactions, no permanent metallic stent protrusion in the main branch, etc. The worldwide experience with the use of bioresorbable scaffolds is limited. In our experience of selected bifurcation lesions, a provisional approach using one scaffold has excellent results. Two-scaffold techniques appeared feasible. Our data support the exploration of the use of bioresorbable scaffolds in more challenging coronary substrates like bifurcations. Prospective registries and ideally randomised trials should assess whether the theoretical benefits of bioresorbable vascular scaffolds (BVS) in bifurcation lesions can produce sustainable good clinical outcomes. PMID- 29588759 TI - Technical Aspects of Provisional Stenting in Percutaneous Treatment of Complex Bifurcation Lesions. AB - Drug-eluting stent (DES) implantation using the 'provisional' approach is the gold standard for percutaneous treatment of patients with unselected bifurcated lesions. Nevertheless, many operators still consider the provisional approach unsuitable for coronary patients with complex bifurcation anatomies. Yet, the provisional approach may be so differently carried out that its procedural outcome is often unpredictable. Some technical refinements may help to anticipate or manage procedural difficulties, which may occur during the management of complex patients. We sought to overview the issues related with DES selection as well as some technical points, which may increase the effectiveness of provisional stenting. In particular, the DES characteristics influencing bifurcation interventions and the technical refinements, which may be considered during a provisional stenting procedure are discussed. Indeed, main vessel stent sizing, proximal optimisation, side branch protection modality, side branch rewiring, kissing balloon and side branch rescue techniques are all pivotal to increase the safety and efficacy of the provisional strategy especially in the setting of complex anatomies and patients. PMID- 29588761 TI - Challenges in Complicated Coronary Chronic Total Occlusion Recanalisation. AB - Percutaneous coronary intervention for chronic total occlusions (CTOs) is still today a challenge even for experienced operators. In the hands of the most experienced the success rate increased from about 60 to 90 % in the past 10 years; paralleled by a long-term patency with drug-eluting stents exceeding 90 %. These results are comparable or even superior to surgical revascularisation. Thanks to Japanese and European CTO club online registries and live courses we are able to rapidly understand and adopt new strategies, techniques and materials to master morphology deemed untreatable 10 years ago. Several of the persistent challenges and solutions unique to CTO interventions are discussed. PMID- 29588760 TI - Current Concepts in the Clinical Utility of Platelet Reactivity Testing. AB - The pharmacodynamic effect of clopidogrel varies among individuals; approximately a third will have high on-treatment platelet reactivity (HTPR) to adenosine diphosphate and may benefit from more intensive antiplatelet therapy. Platelet reactivity testing has an important role in monitoring the therapeutic efficiency of clopidogrel and the safety of more potent drugs that confer an increased bleeding risk, because it provides a direct measure of the biological effect of these drugs. Numerous studies have demonstrated an association between HTPR and the risk of cardiac events in acute coronary syndrome (ACS) or after percutaneous coronary intervention (PCI). While the prognostic value of platelet reactivity testing following PCI has been demonstrated repeatedly in cohort studies and meta analyses, randomised controlled studies investigating the clinical utility of the technique to guide treatment decisions failed to improve clinical outcomes of clopidogrel-treated patients undergoing stent implantation. Available data suggest that platelet function monitoring may be carried out in clopidogrel treated patients with a higher risk of thrombotic events. These include patient risk factors such as body mass index (BMI), type 2 diabetes, and those prior unexpected ischemic events such as stent thrombosis, as well as procedural risk factors. As we move towards conclusively defining a therapeutic window associated with both cardiovascular (upper threshold) and bleeding risk (lower threshold) for antiplatelet agents, platelet reactivity testing will become a central tool in the practice of personalised strategies. PMID- 29588762 TI - The Anatomic-Functional Duality of So-called 'Significant' Atherosclerotic Stenosis - Update on Invasive Diagnostic Strategies in Coronaropathy. AB - So-called 'significant' atherosclerotic coronary stenosis is defined by a simple binary morphological index of tightness - percent diameter stenosis (%DS >50 %). Invasive diagnosis of atherosclerotic coronary lesions classically comprises two consecutive stages, which can be fairly accurately described as angiographic visual perception and functional deduction. This anatomic-functional duality should be seen as not so much antithetic as causal and finally quite complex. The present update seeks to: define the ambiguous relationship between functional impact and morphology in atherosclerotic coronary stenosis; to specify the means of invasive diagnosis complementing coronary angiography to compensate the anatomic and functional limitations intrinsic to the latter (cross-sectional intravascular ultrasound [IVUS] and optical coherence tomography [OCT] imaging and fractional flow reserve [FFR] determined by pressure guide); and to bring these preliminary considerations to bear on the design of algorithms to guide the use of complementary invasive diagnostic exploration and draw up a novel diagnostic strategy in interventional cardiology (first-line coronary angiography). PMID- 29588763 TI - Catheter-based Renal Sympathetic Denervation - Long-term SymplicityTM Renal Denervation Clinical Evidence, New Data and Future Perspectives. AB - Hypertension is one of the most prevalent chronic diseases worldwide and the incidence of resistant hypertension is increasing. Catheter-based renal denervation (RDN) offers a new approach to reaching blood pressure goals by targeting the renal nerves. The technique has demonstrated significant and sustained reductions in blood pressure (BP) in the Symplicity HTN-1 and Symplicity HTN-2 clinical trials. The Global SYMPLICITY Registry aims to demonstrate safety and effectiveness in a 'real-world' patient population. Real world RDN experience has emphasised that patient selection is crucial to successful outcomes; a multidisciplinary referral network is recommended to increase awareness of the procedure and identify patients who are likely to respond best to RDN. Further advances in catheter technology have led to the development of the multi-electrode Symplicity SpyralTM multi-electrode catheter; preliminary data from the feasibility study using the Symplicity Spyral catheter indicate clinical efficacy and procedural safety with reduced procedure times. The Symplicity Spyral catheter is not yet commercially available. The indications of RDN may also expand beyond resistant hypertension - encouraging data have been seen in patients with moderate treatment resistant hypertension. Furthermore, RDN may be beneficial in other clinical states characterised by sympathetic nervous system overactivation including heart failure and chronic kidney disease. Additional data are needed to evaluate the efficacy of RDN in these disease states. PMID- 29588764 TI - Application in Hypertension of Renal Sympathetic Denervation - A Review. AB - Afferent and efferent sympathetic nerves of the kidney located in the adventitia of the renal artery are involved in the regulation of blood pressure and play a pathophysiological role in the progression and maintenance of hypertension. Renal sympathetic denervation is a potent and safe catheter-based therapeutic approach for the treatment of patients with resistant hypertension. Clinical trials of renal sympathetic denervation have shown significant reduction in blood pressure, which was associated with a reduction in local renal norepinephrine spillover as well as a reduction of whole body sympathetic activation in resistant hypertensive patients. PMID- 29588766 TI - Overcoming the Challenges of the Transfemoral Approach in Transcatheter Aortic Valve Implantation. AB - Transcatheter aortic valve implantation (TAVI) is performed through a retrograde transfemoral approach in approximately 80-90 % of cases thanks to the improvements in delivery catheter profile, size and steerability compared with the first generation devices. The aim of this review article is to describe the challenges of transfemoral TAVI and the options to overcome them. The difficulties may be related to the access itself or the placement of the valve using the transfemoral route. Comprehensive patient screening using multislice computed tomography and crossover techniques to prevent bleeding should result in low complication rates even for fully percutaneous procedures. Horizontal ascending aorta and severely calcified aortic valves remain a challenge for retrograde valve crossing, device advancement and accurate positioning during deployment. The buddy balloon technique is a simple option in the case of difficult aortic valve crossing with a delivery catheter, whereas an antegrade approach using the transapical route is a reasonable alternative in such anatomy. PMID- 29588765 TI - Concurrent Coronary Artery and Valvular Heart Disease - Hybrid Treatment Strategies in 2013. AB - Concomitant coronary artery disease (CAD) and valvular heart disease is an increasingly common problem in the ageing population. Hybrid procedures combine surgical and transcatheter approaches to facilitate minimally invasive surgery or to transform a single high-risk open surgery into two less risky procedures. In ideal circumstances, this strategy may decrease the surgical risk in elderly, high-risk and reoperative surgical candidates, while improving patient comfort, convenience and cost-effectiveness. Hybrid procedures can be performed in a staged fashion or as a 'one-stop' procedure in a hybrid operating suite. Increasing evidence supports the safety and short-term efficacy of hybrid valve repair or replacement and coronary revascularisation procedures. Nevertheless, important questions remain, including the optimal timing of the individual procedures and the optimal antiplatelet therapy after percutaneous coronary intervention. With ongoing advances in procedural techniques and anticoagulation strategies, as well as the accumulation of long-term outcomes data, hybrid approaches to concomitant CAD and valvular heart disease will likely become increasingly common.

AB - This article attempts to present some highlights from the rich economic literature pertaining to interventional cardiology and transcatheter aortic valve implantation (TAVI). There are currently more questions than answers, not surprisingly given the pace of technological change in interventional cardiology. For clinicians who work in a strictly regulated environment and have limited control over their use of medical technologies, this article will hopefully shed some light on the motives for policy decisions. For clinicians who make decisions on the resources used to treat their patients, it aims to provide the means of looking for evidence that will allow for informed decisions from both clinical and economic perspectives. PMID- 29588769 TI - Foreword. PMID- 29588768 TI - No Racial Disparities in the Treatment of ST Elevation Myocardial Infarction - A Community-based Experience. AB - Whether racial disparities exist in the treatment of ST elevation myocardial infarction (STEMI) is not exactly known. We report a retrospective chart review of patients with first event of STEMI, in two groups separated by one decade. Results revealed that hospital mortality in the 2007 and 1997 groups for African Americans versus Caucasians was one of 22 versus 21 of 170, 95 % confidence interval (CI) -0.178 to 0.022, p=0.48 and four of 41 versus 39 of 402, 95 % CI 0.095 to 0.096, p=1.00, respectively. The mean length of stay (LOS) for African Americans and Caucasians in the 2007 and 1997 groups was 5.7 versus 4.1 days (p=0.09) and 7.3 versus 6.6 days (p=0.42), respectively. During follow-up, a total of 40 patients needed re-intervention in the 2007 group. The re intervention rate in African American patients being 13.6 % (three of 22) versus 21.2 % (36 of 170) in Caucasians, 95 % CI -0.231 to 0.081, with p=0.57. In conclusion, there was no evidence of racial disparity in the treatment of STEMI in terms of hospital mortality, length of hospital stay and re-intervention rate. PMID- 29588770 TI - European Society of Cardiology ST-segment Elevation Myocardial Infarction Guidelines in Perspective - Focused on Primary Percutaneous Coronary Intervention. AB - Patients suffering acute myocardial infarction with ST-segment elevation myocardial infarction (STEMI) require full attention of the whole STEMI network to save their lives and to improve the quality of life after a heart attack. Implementation of the most recent European Society of Cardiology (ESC) and American College of Cardiology/American Heart Association (ACC/AHA) STEMI Guidelines into the practice is the holy grail of the healthcare systems and all stakeholders. In relation to this, the Stent for Life Initiative can serve as one of very successful and effective models in Europe and beyond. Although the evidence-based approach may be applied to majority of patients, the tailored and updated therapy needs to be modified in concordance with the patients' risk profile, experience and availability of medical resources. Some 'hot topics', issues, differences between the ESC and ACC/AHA Guidelines, latest information and perspectives are discussed in this short review; focused on primary percutaneous coronary intervention (PCI) as the most effective reperfusion therapy. PMID- 29588771 TI - The Role of Self-expanding Stents in Patients with Atypical Coronary Anatomy. AB - Despite advances with new generation stents, there remains some atypical coronary anatomy where optimal stenting continues to be a challenge; such as stent sizing in large, ectatic or aneurysmal vessels; tapered vessels; and in vasoconstricted arteries such as in ST-segment elevation myocardial infarction or chronic total occlusions. Balloon-expandable stents are tubular and cannot easily accommodate vessel diameter variations; thrombotic vessels increase the risk of distal embolisation and no-reflow; positive remodelling and vasodilation often result in subsequent malapposition; and patients with bifurcation lesions have a higher risk of adverse events. The STENTYS BMS and DES(P) stents have a self-expanding design, which enables a better anatomical fit to the vessel, even with diameter variations (up to 6.0 millimetres [mm]), and can adapt to changes in vessel size over time. The stents deploy atraumatically from distal to proximal, which could reduce distal embolisation and contain disconnectable bridges, which can be opened up at a side branch. Self-apposing technology could therefore provide a potential solution to current challenges with balloon-expandable stent technology. PMID- 29588772 TI - Overview of Technical and Cost Considerations in Complex Percutaneous Coronary Intervention. AB - Complex percutaneous coronary intervention (PCI), encompassing an ever-expanding range of challenging lesion sets and patient populations, accounts for a significant proportion of PCI procedures being performed currently. Specific lesion types associated with lower rates of procedural success and higher rates of recurrence or major adverse cardiac events (MACE) include multivessel disease, unprotected left main coronary artery disease, fibrocalcific or undilatable lesions, chronic total occlusions, degenerated saphenous vein graft lesions, thrombotic lesions, and bifurcation disease. Validated tools and technical strategies currently exist to address most procedural scenarios encountered and should be familiar to the complex PCI operator. Anticipated clinical outcomes, projected resource utilization, and cost considerations should all factor into the decisions of when, how, and in whom to intervene. PMID- 29588773 TI - The Bioresorbable Stent in Perspective-How Much of an Advance is It? AB - The novel idea of bioresorbable stent technology continues to fascinate the interventional community. This article aims to provide a concise and balanced overview of the available technology and clinical evidence. Both potentially positive and negative aspects of bioresorbable stents in different lesion subsets and clinical situations are discussed. PMID- 29588774 TI - Trans-catheter Aortic Valve Implantation Guidelines - Does the Latest Evidence Change our Views? AB - From the wealth of recent registries and trials scrutinising its performance, trans-catheter aortic valve implantation (TAVI) emerges as a viable and rapidly established option, both when compared to medical treatment in inoperable patients and when compared to conventional surgical treatment in high-risk patients. Results consistently demonstrate improvement in functional status and outcome; however, appropriate patient selection remains crucial as high-risk cohorts become apparent. PMID- 29588775 TI - Surgical Approaches to Aortic Valve Replacement and Repair-Insights and Challenges. AB - Since 1960, surgical aortic valve replacement (sAVR) had been the only effective treatment for symptomatic severe aortic stenosis until the recent development of transcatheter aortic valve replacement (TAVR). TAVR has offered an alternative, minimally invasive treatment approach particularly for patients whose age or co morbidities make them unsuitable for sAVR. The rapid and enthusiastic utilization of this new technique has triggered some speculation about the imminent demise of sAVR. We believe that despite the recent advances in TAVR, surgical approach to aortic valve replacement has continued to develop and will continue to be highly relevant in the future. This article will discuss the recent developments and current approaches for sAVR, and how these approaches will keep pace with catheter-based technologies. PMID- 29588776 TI - Adoption of Transcatheter Aortic Valve Implantation in Western Europe. AB - Transcatheter aortic valve implantation (TAVI) is a novel therapeutic option for patients with severe symptomatic aortic stenosis (AS) at excessive or high surgical risk for conventional surgical aortic valve replacement. First commercialised in Europe in 2007, TAVI growth has been exponential among some Western European nations, though recent evidence suggests heterogeneous adoption of this new and expensive therapy. Herein, we review the evidence describing the utilisation of TAVI in Western Europe. PMID- 29588777 TI - Transcatheter Aortic Valve Replacement in Moderate-risk Aortic Stenosis Patients. AB - The Placement of Aortic Transcatheter Valves (PARTNER) trial showed the effectiveness of transcatheter aortic valve replacement (TAVR) for inoperable patients and non-inferiority for mortality versus open valve replacement. There are three questions concerning the role of TAVR for intermediate-risk patients. These relate to: institutional and surgeon results, physician and hospital alignments, and who will pay. PMID- 29588778 TI - Percutaneous Paravalvular Leak Closure. AB - Symptomatic paravalvular leak (PVL) complicates up to 12 % of surgical valve replacements. When patients present with congestive heart failure and/or haemolysis, reoperation for repeat valve replacement may be undertaken, but presents greater risk and lower likelihood of success than the initial operation. Therefore, percutaneous approaches to PVL closure have been developed by specialists in structural cardiac intervention. Large series demonstrate high levels of procedural success and promising clinical outcomes for this complex intervention. A thorough understanding of multimodality imaging is necessary for the diagnosis of PVL and the safe and successful performance of these closure procedures. PMID- 29588779 TI - Transcatheter Mitral Valve Devices - Functional Mechanical Designs. AB - Mitral regurgitation is a complex disorder involving a multitude of components of the mitral apparatus. With the desire for less invasive treatment approaches, transcatheter mitral valve therapies (TMVT) are directed at these components and available at varying stages of development. Therapeutic advancements and the potential to combine technologies may further improve their efficacy and safety. Transcatheter mitral valve replacement, while preserving the mitral apparatus, may emerge as an alternative or even a more suitable treatment option. In addition, early data on transcatheter mitral valve-in-valve and valve-in-ring implantation are encouraging and this approach may be an alternative to reoperation in the high-risk patient. This review details the expanding functional mechanical designs of current active TMVT. PMID- 29588781 TI - Foreword. PMID- 29588780 TI - Renal Sympathetic Denervation - A Review of Applications in Current Practice. AB - Resistant hypertension is associated with high morbidity and mortality despite numerous pharmacological strategies. A wealth of preclinical and clinical data have demonstrated that resistant hypertension is associated with elevated renal and central sympathetic tone. The development of interventional therapies to modulate the sympathetic nervous system potentially represents a paradigm shift in the strategy for blood pressure control in this subset of patients. Initial first-in-man and pivotal, randomised controlled trials of endovascular, radio frequency renal sympathetic denervation have spawned numerous iterations of similar technology, as well as many novel concepts for achieving effective renal sympatholysis. This review details the current knowledge of these devices and the evidence base behind each technology. PMID- 29588783 TI - ABSORB BVS Implantation in Bifurcation Lesions - Current Evidence and Practical Recommendations. AB - The introduction of the ABSORB bioresorbable vascular scaffold (BVS) provides a new tool for stenting in interventional cardiology. Initially, relatively simple coronary artery lesions were treated with this novel device; nowadays, we are gaining clinical experience when treating a wide variety of lesions with the ABSORB BVS, including bifurcation lesions. Unfortunately, data are limited in terms of the use of the ABSORB BVS in coronary bifurcation lesions, so little is known about the safety and feasibility of these procedures. Bench testing and case reports showed that single provisional scaffold placement is feasible with fenestration of the scaffold towards the side branch and sequential non-compliant balloon inflation in the side and main branches. However, no prospective randomised clinical data with optical coherence tomography (OCT) imaging for different bifurcation stenting techniques are available. Based on the available data and our own experience we would recommend the use of the provisional single scaffold technique and only to fenestrate the scaffold if a severely pinched ostium combined with impaired flow seen on angiogram. PMID- 29588782 TI - Risks of Stroke After Coronary Artery Bypass Graft - Recent Insights and Perspectives. AB - Stroke is one of the most devastating complications after coronary artery bypass graft (CABG) surgery, entailing permanent disability, a 3-6 fold increased risk of mortality, an incremental hospital resource consumption and a longer length of hospital stay. Notwithstanding advances in surgical, anaesthetic and medical management across the last 10 years, the risk of stroke after CABG has not significantly declined, likely because an older and sicker population is now deemed suitable to undergo CABG. The pathogenesis of stroke is multifactorial, but two variables are believed to play a major role - cerebral embolisation of atheromatous debris arising from the ascending aorta during surgical manipulation and hypoperfusion during surgery. Identification of vulnerable patients at increased risk of stroke before CABG is of paramount importance for the surgical decision-making approach and informed consent. Several models including demographic, clinical and procedural variables have been developed to risk stratify the hazard of stroke in patients undergoing CABG, but identification of severe atherosclerosis of the ascending aorta and pre-existing cerebrovascular disease are key determinants for appropriate risk stratification and decision making. Atherosclerotic disease of the ascending aorta can be identified before surgery using transoesophageal echocardiography, computed tomography and magnetic resonance imaging. However, intra-operative ultrasound scanning of the ascending aorta is the diagnostic tool with the best sensitivity and specificity for the detection of atheromatous debris in the ascending aorta. Although many investigators have advocated the use of off-pump CABG to minimise the risk of peri-operative stroke, results from randomised trials and meta-analyses have been inconsistent. Anaortic approaches, including total arterial revascularisation with in situ grafting of both mammary arteries, or the use of the HEARTSTRING(r) seal device avoid any manipulation of the aorta, thus potentially minimising the risk of stroke in high-risk patients. Assessment and treatment of severe carotid artery disease, and aggressive and prompt treatment of post-operative atrial fibrillation are other important strategies that should be routinely implemented to reduce the risk of stroke in patients undergoing CABG. PMID- 29588784 TI - Clinical Impact of Stent Design. AB - The introduction and widespread adoption of drug-eluting stents into routine clinical practice has seen tremendous changes in the practice of interventional cardiology. For a prolonged period, manufacturers have focused research on drugs and polymers that are the key to the prevention of in-stent restenosis. However, stent platform design and its clinical implications have now come back to the fore. This has occurred for numerous reasons, but has primarily been driven by the need for modern stents to perform well in increasingly demanding clinical scenarios. This paper reviews the historical evolution of stent platform design. Current manufacturing processes and materials are also explored. Geometric stent construction and its implications for longitudinal stability and the longer term risks of stent fracture are reviewed. Finally, the implications of the specific stent chosen for different clinical applications including the treatment of bifurcations and left main disease are also summarised. This article will familiarise cardiologists with the crucial impact of each of these factors on modern day practice, as well as acute and long-term outcomes for patients. PMID- 29588785 TI - Current Antithrombotic Therapy in Patients with Acute Coronary Syndromes Undergoing Percutaneous Coronary Interventions. AB - Acute coronary syndromes (ACS) represent a life-threatening complication of the systemic atherosclerotic process, affecting the coronary circulation. Thrombosis, defined as an uncontrolled activation of the endogenous thrombogenetic reparative process, often follows atherosclerotic plaque damage and is mainly engaged by two main pathways: platelet aggregation and coagulation. Therefore, antithrombotic therapy to modulate either pathway plays an important role for the reduction of ischaemic adverse events in ACS patients. Since the advent of aspirin and warfarin, numerous antiaggregant and anticoagulant molecules have been developed to achieve this goal, but their anti-ischaemic efficacy is often obtained at the price of augmented bleedings, which are known to be strong predictors of adverse outcome. This article briefly reviews the physiopathological mechanisms of thrombosis and presents an overview of the available literature supporting the use of these major drugs, as well as the European Society of Cardiology recommendations for their utilisation in the setting of non-ST and ST-elevation myocardial infarction undergoing invasive treatment. PMID- 29588786 TI - Use of Thrombectomy Devices in Primary Percutaneous Interventions for ST elevation Myocardial Infarction - An Update. AB - Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion modality in patients with ST-elevation myocardial infarction (STEMI). While PPCI is highly effective in achieving epicardial coronary reperfusion, a significant proportion of patients fail to achieve adequate myocardial reperfusion. This is in part due to the distal microembolisation of thrombus and plaque debris during PCI. Recognition of this has led to the development of a number of devices with different mechanisms of action that aim to reduce such distal embolisation and therefore improve end myocardial perfusion. Study results of thrombectomy devices however have been largely inconsistent, especially about clinical outcome data, and several meta-analyses have been carried out as a result. This review aims to critically analyse the literature data on thrombectomy during PPCI, taking into account the most recent studies and the latest meta-analyses looking to see whether thrombectomy use is associated with improved outcomes. PMID- 29588788 TI - Review of Data and Discussion - Who Should Undergo Patent Foramen Ovale Closure in 2014? AB - A patent foramen ovale is a relatively common finding in the general population and is associated with a number of conditions, including cryptogenic stroke. In 2014, percutaneous patent foramen ovale (PFO) closure is a frequently performed procedure; the bulk of these procedures being carried out for secondary prevention of cryptogenic stroke, along with other indications, such as prevention of decompression illness, platypnoea-orthodeoxia syndrome and migraine. Of these conditions the largest body of evidence available is for cryptogenic stroke and there is ongoing debate of the benefit of PFO closure over medical therapy. This article will review the available evidence of PFO closure in each of these contexts, with a particular focus on randomised controlled trials, and endeavour to outline in whom the evidence suggests closure should be considered. PMID- 29588787 TI - Alcohol Septal Ablation for the Treatment of Hypertrophic Obstructive Cardiomyopathy. AB - Hypertrophic cardiomyopathy (HCM) is an inherited myocardial disorder characterised by left ventricular hypertrophy. A subgroup of patients develops limiting symptoms in association with left ventricular outflow tract obstruction (LVOTO). Current international guidelines recommend that symptomatic patients are initially treated by alleviating exacerbating factors and negatively inotropic medication. Drug-refractory symptoms require a comprehensive evaluation of the mechanism of LVOTO and review by a multidisciplinary team to consider the relative merits of myectomy, alcohol septal ablation (ASA) and pacing. This article provides a brief overview of HCM and the pathophysiology of LVOTO, and reviews the use of ASA in patients with drug-refractory symptoms secondary to LVOTO. PMID- 29588789 TI - Differences in Outcomes and Indications between Sapien and CoreValve Transcatheter Aortic Valve Implantation Prostheses. AB - Transcatheter aortic valve implantation (TAVI) has emerged as a suitable alternative to surgical valve replacement for patients with severe, symptomatic, calcified aortic stenosis and a background of co-morbidities, which can make surgery a high-risk option. It has also evolved as an alternative for degenerative prosthetic heart valve disease. Since the inception of TAVI in 2002, the two main devices in routine clinical use are the Edwards Sapien valve (since 2006) and the Medtronic CoreValve (since 2007). The more recent Sapien XT valve and Sapien 3 have been in clinical use since 2010 and 2013, respectively. In addition to registry data on these devices, there are a number of completed and ongoing randomised controlled trials, including one comparing the two devices. The aim of this article is to discuss the differences in indications and outcomes between these two prostheses. PMID- 29588790 TI - Transcatheter Aortic Valve Replacement and Left Atrial Appendage Occlusion - A Stitch in Time? AB - Many patients have now been able to receive transcatheter aortic valve replacement (TAVR) therapy for severe aortic stenosis. These patients have atrial fibrillation and are placed on warfarin for stroke prophylaxis. The opportunity for treatment with left atrial appendage occlusion (LAAO) in place of warfarin for this population exists, especially for those with increased bleeding risk. This paper discusses the prevalence and aetiology of stroke in patients presenting for TAVR (with a focus on the risk from chronic and acute atrial fibrillation) and also the benefit of LAAO closure in this population. PMID- 29588791 TI - Transcatheter Aortic Valve Implantation Without General Anaesthetic. AB - Transcatheter aortic valve implantation (TAVI) procedures are increasingly being performed under local anaesthetic, generally with sedation. Operators hope this will reduce mortality, morbidity and length of hospital stay. A general anaesthetic (GA), however, although involving intrinsic risk, permits transoesophageal echocardiogram (TOE) imaging throughout a procedure as well as eliminating patient anxiety, pain and movement. This article reviews the published literature, all single-centre experiences, comparing TAVI procedures performed with and without a GA. Procedures performed without GA are generally shorter with reduced length of stay compared with those performed under GA. There is no evidence of any difference in outcomes. PMID- 29588792 TI - Foreword. PMID- 29588793 TI - Fractional Flow Reserve Derived from Coronary Imaging and Computational Fluid Dynamics. AB - The assessment of functional severity of atherosclerotic stenoses in patients with coronary artery disease by invasive fractional flow reserve (FFR) measurement requires coronary artery cannulation, advancement of a wire and intravenous adenosine infusion with inherent procedure-related risk and costs. Coronary computed tomographic angiography (CCTA) and rotational coronary angiography (RA) have been recently used in conjunction with computational fluid dynamics (CFD) and image-based modelling for the determination of FFR without the need for additional imaging, modification of acquisition protocols or administration of medication. FFR derived from CCTA was demonstrated as superior to measures of CCTA stenosis severity for determination of lesion-specific ischaemia. Estimation of FFR from RA images and CFD provides a less invasive alternative to conventional FFR measurement while estimated values are in agreement with measured values. These new, combined anatomic-functional assessments have the potential to simplify the noninvasive diagnosis of coronary artery disease with a single study to identify patients with ischaemia-causing stenosis who may benefit from revascularisation. PMID- 29588794 TI - Intravascular Ultrasound-based Imaging Modalities for Tissue Characterisation. AB - Atherosclerosis is the leading cause of cardiovascular mortality and morbidity in the developed world. Intravascular ultrasound (IVUS) is a widely used imaging modality providing complementary diagnostic information to angiography regarding the vessel wall of the coronary arteries. IVUS has been used for assessment of ambiguous angiographic lesions, evaluation of new interventional devices and in atherosclerosis progression-regression trials. However, the standard gray-scale IVUS has limited value for the accurate identification of specific plaque components. This limitation has been partially over- come by introduction of new IVUS-based imaging methods such as: virtual histology IVUS, iMAP-IVUS and Integrated Backscatter IVUS. These methods utilise the ultrasound backscatter signal to enable a more detailed characterization of plaque morphology or tissue characterization and to provide insight on the features of vulnerable plaque. PMID- 29588795 TI - Impact of Intravascular Ultrasound in Clinical Practice. AB - Intravascular ultrasound (IVUS) has expanded our understanding of atherosclerotic plaque morphology, and provides an opportunity to guide cardiovascular interventions and evaluate results. Use of this technique requires understanding of ultrasound physics, catheter differences, skills in vessel, plaque and stent quantification and knowledge of artifacts and various physiologic and pathologic findings. Optimal cardiovascular interventions should result in absence of inflow or outflow obstruction, precise geographic landing, while attaining the largest feasible luminal gain without plaque protrusion, vessel dissection or perforation and, if deployed, with complete stent expansion and apposition to the vessel wall. IVUS is safe, cost efficient and effectively optimises cardiovascular interventions. In addition, IVUS improves outcomes when used to guide coronary interventions using bare metal stents (BMS) and drug eluting stents (DES). The role of IVUS in endovascular therapy is rapidly expanding. This review will focus on the impact of IVUS in clinical practice. PMID- 29588796 TI - Optimum Utilisation of Novel Antiplatelet Agents in Clinical Practice. AB - Prasugrel and ticagrelor are two novel promising antiplatelet agents inhibiting the platelet activation via the adenosine diphosphate pathway. Both achieve a faster, more intense, and more consistent platelet inhibition than clopidogrel. Both novel antiplatelet agents have demonstrated superiority over clopidogrel in large, randomised controlled trials in patients with acute coronary syndrome (ACS). Prasugrel may be best suited for younger patients with planned percutaneous coronary intervention and large areas of myocardium at risk or diabetes mellitus who have a low risk of bleeding. The benefits of prasugrel relative to clopidogrel in ACS must be weighed against the increase in the risk of bleeding associated with its use. Ticagrelor may be the best option for patients with ACS without T elevations, elderly patients or patients managed conservatively. Vorapaxar, a new oral protease-activated-receptor 1 antagonist, may be a good option for secondary prevention in patients with stable atherosclerosis and no history of stroke. PMID- 29588797 TI - MGuard Embolic Protection Stent - The Importance of Thrombus Management in ST elevation Myocardial Infarction Primary Percutaneous Coronary Intervention: Proceedings of STEMI symposium at EuroPCR on 20-23rd May 2014 in Paris. AB - Distal embolisation of atherothrombotic material is a frequent consequence of percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI). This causes microvascular occlusions, leading to a further reduction in myocardial reperfusion. The MGuardTM embolic protection stent (EPS) features a unique polymer micronet mesh coating. When used in acute STEMI, the MGuard EPS shows significant improvement in myocardial flow and ST resolution, even in complicated clinical cases vs the standard approach with conventional bare metal or drug-eluting stents. Data from the andomised Safety and Efficacy Study of MGuard Stent After a Heart Attack (MASTER II) trial and from a real-life registry have shown the efficacy and safety of the MGuard in primary PCI. This report of the proceedings of a symposium at EuroPCR, 20-23 May 2014, Paris, France, discussed clinical trial data, as well as a number of clinical cases, illustrating the utility of the MGuard EPS in difficult situations. PMID- 29588798 TI - Bioresorbable Scaffolds. AB - Percutaneous coronary intervention (PCI) has undergone major advances including the evolution in stent technology, from bare metal stents (BMS), to their drug eluting counterparts, to the development of bioresorbable scaffolds (BRS). The primary notion of BRS was to facilitate complete vascular healing and restore normal endothelial function following the resorption of stent scaffold while providing equivalent mechanical properties of a metallic drug eluting stents (DES) in the earlier stages. BRS provide attractive physiologic advancements over the existing DES and have shown promising results in initial clinical studies albeit with small sample sizes. Their use has been primarily restricted to patients recruited in clinical trials with limited real-world applicability. Thus, data from larger randomised control trials is awaited. The major objective of this article is to review the evidence on BRS and identify their clinical applicability in current interventional practice. PMID- 29588799 TI - Cre8TM Unique Technology in Challenging Daily Practice: Proceedings of a satellite symposium held at EuroPCR on 20th - 23rd May 2014 in Paris. AB - The use of drug-eluting stents (DES) has improved clinical outcomes in percutaneous coronary intervention (PCI) procedures. However, first-generation DES were associated with safety concerns arising from the persistence of durable polymers, including late stent thrombosis. The Cre8TM DES is a novel polymer-free stent designed to overcome these issues. In a presentation at EuroPCR 2014, two clinical cases were discussed. The first was a case of high bleeding risk; the second was the case of multivessel disease with a significant risk of stent restenosis. Together, these cases illustrated the complexity of decision-making in PCI in daily practice. In both cases, the Cre8TM DES offered a safe and effective solution to these challenging cases. PMID- 29588800 TI - Meeting the Unmet - The Cre8 Polymer-free Drug-eluting Stents Technology: Proceedings of a satellite symposium held at EuroPCR on May 20th - 23rd 2014 in Paris. AB - The use of first-generation drug-eluting stents (DES) has been associated with safety concerns such as very late stent thrombosis. Today, with the release of newer DES, there is a need for comparative studies of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) to demonstrate their value in patients with high risk of restenosis such as diabetic patients. In a satellite symposium presented at EuroPCR 2014, the Cre8TM DES was discussed. The Cre8 device has a number of unique clinical features, including polymer-free technology, abluminal reservoir technology and bio-inducer surface that ensure effective neointima suppression and rapid endothelialisation. The efficacy of the Cre8 DES has been demonstrated in the International randomised comparison between DES Limus Carbostent and Taxus drug-eluting stents in the treatment of de novo coronary lesions (NEXT) randomised clinical study, with equivalent efficacy in the diabetic and general populations, a unique finding. Ongoing clinical studies such as Investig8 and the Tel Aviv Medical Center (TLVMC) Cre8 study have confirmed the efficacy of the device in patient populations with a high proportion of diabetic patients. The Demonstr8 randomised trial has shown almost complete Cre8 strut coverage at three months with a numerical advantage versus bare metal stent (bare metal stents [BMS] - comparator device) at one month. In addition, use of the Cre8 DES may enable a shorter duration of dual antiplatelet therapy (DAPT) following PCI. The Cre8 DES therefore represents a significant advance in stent technology and may be particularly useful in challenging clinical settings. PMID- 29588801 TI - Evidence for Benefit of Percutaneous Coronary Intervention for Chronically Occluded Coronary Arteries (CTO) - Clinical and Health Economic Outcomes. AB - Percutaneous revascularisation of a coronary chronic total occlusion (CTO) remains one of the technical frontiers of interventional cardiology. CTOs are common, and yet intervention is only attempted in 10 % of cases. CTO procedures are perceived to be technically challenging, lengthy, associated with significant risk and have only limited data to support the practise. Recent technical advances have dramatically increased the success rate, shortened procedural time and improved clinical outcomes. The aim of this article is to critically examine the data that supports CTO intervention, including specifically an appraisal of procedural safety, benefit and overall cost effectiveness. PMID- 29588802 TI - Percutaneous Treatment of Coronary Chronic Total Occlusions Part 1: Rationale and Outcomes. AB - Coronary chronic total occlusions (CTOs) are commonly encountered in patients with coronary artery disease. Compared to patients without coronary CTOs, those with CTO have worse clinical outcomes and lower likelihood of complete coronary revascularisation. Successful CTO percutaneous coronary intervention (PCI) can significantly improve angina and improve left ventricular function. Although currently unproven, successful CTO PCI might also reduce the risk for arrhythmic events in patients with ischaemic cardiomyopathy, provide better tolerance of future acute coronary syndrome, and possibly improve survival. Evaluation by a heart team comprised of both interventional and non-interventional cardiologists and cardiac surgeons is important for determining the optimal revascularisation strategy in patients with coronary artery disease and CTOs. Ad hoc CTO PCI is generally not recommended, so as to allow sufficient time for (a) discussion with the patient about the indications, goals, risks, and alternatives to PCI; (b) careful procedural planning; and (c) contrast and radiation exposure minimisation. Use of drug-eluting stents is recommended for CTO PCI, given the lower rates of angiographic restenosis compared to bare metal stents. PMID- 29588803 TI - Percutaneous Treatment of Coronary Chronic Total Occlusion Part 2: Technical Approach. AB - Dual injection is recommended for nearly all chronic total occlusion (CTO) percutaneous coronary intervention (PCI) to determine the optimal crossing strategy and guide wire advancement into the distal true lumen. Strategies that provide enhanced guide catheter support (such as long sheaths, large-bore guiding catheters, use of guide catheter extensions, and anchor techniques) are important for maximising the success rate and efficiency of CTO PCI. Use of a microcatheter or over-the-wire balloon is strongly recommended in CTO PCI for enhancing the penetrating power of the guidewire, enabling change in tip shape and allowing guidewire change (stiff CTO guidewires are not optimal for crossing non-occluded coronary segments). Adherence to a procedural strategy that standardises CTO technique and facilitates procedural success is recommended. Such a strategy would permit stepwise decision-making for antegrade and retrograde methods; inform guidewire selection; and incorporate alternative approaches for instances of initial failure. Given the paucity of long-term outcomes with use of novel crossing techniques (antegrade dissection/re-entry and retrograde), antegrade wire escalation is the preferred CTO crossing technique, if technically feasible. Using measures to minimise radiation exposure (including but not limited to use of 7.5 frames per second fluoroscopy and use of low magnification) and contrast administration is recommended. CTO PCI is best performed at centres with dedicated CTO PCI experience and expertise. Use of crossing difficulty prediction tools, such as the J-CTO score, can facilitate the selection of cases with a high likelihood of quick crossing that can be attempted at less experienced centres. PMID- 29588804 TI - New Advances in Chronic Total Occlusions. AB - Coronary chronic total occlusions (CTOs) still represent the greatest technical challenge that interventional cardiologists face. CTOs remain seriously undertreated with percutaneous techniques, far below their prevalence. One reason for the low uptake was the suboptimal CTO percutaneous coronary intervention (PCI) success rates over a long period of time. During the last years, dedicated groups of experts in Japan, Europe and United States fostered the development and standardisation of modern CTO recanalisation techniques, along with providing focused training and proctorship worldwide. As a result, dedicated operators achieved success rates far beyond 90 %, while coping with lesions of increasing complexity. A series of studies, mainly retrospective and observational in nature, explored the prognostic impact of CTO PCI, revealing that successful lesion recanalisation is related to improved patient outcome and anginal status; further evidence from randomised trials is on the way. The following review reports on the most recent advances in the field of CTO recanalisation, in an attempt to promote a more balanced approach in patients with chronically occluded coronary arteries and encourage more operators to cope with these inherently complex lesions. PMID- 29588805 TI - Contemporary Techniques for Coronary Chronic Total Occlusions Revascularisation: Sharing Experience in a Global World: Proceedings of a satellite symposium held at EuroPCR on May 20th - 23rd 2014 in Paris Katrina Mountfort, Medical Writer, Radcliffe Cardiology. AB - Chronic total occlusions (CTO) are the most challenging lesions treated by interventional cardiologists. A symposium at EuroPCR 2014 discussed factors influencing the success of percutaneous intervention (PCI) in CTO. Current treatment paradigms suggest that one or two vessel disease should be treated by PCI while three-vessel disease requires surgery if complete revascularisation cannot be achieved with PCI. In patients with CTO and multi-vessel disease timing is key, and evidence of ischaemic burden and expected completeness of revascularisation is required before PCI is undertaken. Other factors affecting procedural success include the available equipment and expertise of the operator. Flexiblity in strategy selection is also important as it is frequently necessary to switch strategies during the procedure. The presentation included two live cases that illustrated the complexity of this procedure. PMID- 29588806 TI - Identifying and correcting epigenetics measurements for systematic sources of variation. AB - Background: Methylation measures quantified by microarray techniques can be affected by systematic variation due to the technical processing of samples, which may compromise the accuracy of the measurement process and contribute to bias the estimate of the association under investigation. The quantification of the contribution of the systematic source of variation is challenging in datasets characterized by hundreds of thousands of features.In this study, we introduce a method previously developed for the analysis of metabolomics data to evaluate the performance of existing normalizing techniques to correct for unwanted variation. Illumina Infinium HumanMethylation450K was used to acquire methylation levels in over 421,000 CpG sites for 902 study participants of a case-control study on breast cancer nested within the EPIC cohort. The principal component partial R square (PC-PR2) analysis was used to identify and quantify the variability attributable to potential systematic sources of variation. Three correcting techniques, namely ComBat, surrogate variables analysis (SVA) and a linear regression model to compute residuals were applied. The impact of each correcting method on the association between smoking status and DNA methylation levels was evaluated, and results were compared with findings from a large meta-analysis. Results: A sizeable proportion of systematic variability due to variables expressing 'batch' and 'sample position' within 'chip' was identified, with values of the partial R2 statistics equal to 9.5 and 11.4% of total variation, respectively. After application of ComBat or the residuals' methods, the contribution was 1.3 and 0.2%, respectively. The SVA technique resulted in a reduced variability due to 'batch' (1.3%) and 'sample position' (0.6%), and in a diminished variability attributable to 'chip' within a batch (0.9%). After ComBat or the residuals' corrections, a larger number of significant sites (k = 600 and k = 427, respectively) were associated to smoking status than the SVA correction (k = 96). Conclusions: The three correction methods removed systematic variation in DNA methylation data, as assessed by the PC-PR2, which lent itself as a useful tool to explore variability in large dimension data. SVA produced more conservative findings than ComBat in the association between smoking and DNA methylation. PMID- 29588807 TI - Placental surface area mediates the association between FGFR2 methylation in placenta and full-term low birth weight in girls. AB - Background: Fibroblast growth factor receptor 2 (FGFR2) gene encodes a protein of the fibroblast growth factor receptor family. FGFR2 gene expression is associated with the regulation of implantation process of placenta which plays a vital role in fetal growth. DNA methylation is widely known as a mechanism of fetal growth. However, it is unclear whether and how DNA methylation of FGFR2 gene in the placenta is associated with full-term low birth weight. This case-control study aims to explore the links between FGFR2 methylation in placenta and full-term low birth weight and to further examine the mediation effect of placental surface area on this association. Results: We conducted analyses for each of the five valid CpG sites at FGFR2 in 165 mother-baby pairs (86 FT-LBW vs. 79 FT-NBW) and found that per one standard deviation increase in the DNA methylation of CpG 11 at FGFR2 was associated with 1.64-fold higher risk of full-term low birth weight (OR = 1.64, 95% CI = [1.07, 2.52]) and 0.18 standard deviation decrease in placental surface area (beta = - 0.18; standard error = 0.08, p = 0.02). The mediation effect of placental surface area on the association between DNA methylation and full-term low birth weight was significant in girls (OR = 1.38, 95% CI = [1.05, 1.80]) but not in boys. The estimated mediation proportion was 48.38%. Conclusion: Our findings suggested that placental surface area mediated the association between DNA methylation of FGFR2 in placenta and full-term low birth weight in a sex-specific manner. Our study supported the importance of placental epigenetic changes in placental development and fetal growth. PMID- 29588808 TI - Physiologically based microenvironment for in vitro neural differentiation of adipose-derived stem cells. AB - The limited capacity of nervous system to promote a spontaneous regeneration and the high rate of neurodegenerative diseases appearance are keys factors that stimulate researches both for defining the molecular mechanisms of pathophysiology and for evaluating putative strategies to induce neural tissue regeneration. In this latter aspect, the application of stem cells seems to be a promising approach, even if the control of their differentiation and the maintaining of a safe state of proliferation should be troubled. Here, we focus on adipose tissue-derived stem cells and we seek out the recent advances on the promotion of their neural differentiation, performing a critical integration of the basic biology and physiology of adipose tissue-derived stem cells with the functional modifications that the biophysical, biomechanical and biochemical microenvironment induces to cell phenotype. The pre-clinical studies showed that the neural differentiation by cell stimulation with growth factors benefits from the integration with biomaterials and biophysical interaction like microgravity. All these elements have been reported as furnisher of microenvironments with desirable biological, physical and mechanical properties. A critical review of current knowledge is here proposed, underscoring that a real advance toward a stable, safe and controllable adipose stem cells clinical application will derive from a synergic multidisciplinary approach that involves material engineer, basic cell biology, cell and tissue physiology. PMID- 29588810 TI - Increased frequency of angina attacks caused by switching a brand-name vasodilator to a generic vasodilator in patients with vasospastic angina: Two case reports. AB - It is well known that calcium channel blockers (CCBs) are the first line of therapy for vasospastic angina (VSA). Here, we report two cases of VSA with an increase in the frequency of angina attacks after switching from a brand-name to a generic CCB. In both cases, angina recurred upon switching from a brand-name CCB to a generic CCB during follow-up. The patients' condition improved upon switching back to the original CCB. Both cases involved a high severity of VSA, based on the results of spasm provocation testing. These findings suggest that, in some patients with severe VSA, the frequency of angina attacks increases when switching from a brand-name CCB to a generic CCB. Cardiologists should consider this factor when prescribing drugs for angina. PMID- 29588809 TI - Evolution of transanal total mesorectal excision for rectal cancer: From top to bottom. AB - The gold standard for curative treatment of locally advanced rectal cancer involves radical resection with a total mesorectal excision (TME). TME is the most effective treatment strategy to reduce local recurrence and improve survival outcomes regardless of the surgical platform used. However, there are associated morbidities, functional consequences, and quality of life (QoL) issues associated with TME; these risks must be considered during the modern-day multidisciplinary treatment for rectal cancer. This has led to the development of new surgical techniques to improve patient, oncologic, and QoL outcomes. In this work, we review the evolution of TME to the transanal total mesorectal excision (TaTME) through more traditional minimally invasive platforms. The review the development, safety and feasibility, proposed benefits and risks of the procedure, implementation and education models, and future direction for research and implementation of the TaTME in colorectal surgery. While satisfactory short term results have been reported, the procedure is in its infancy, and long term outcomes and definitive results from controlled trials are pending. As evidence for safety and feasibility accumulates, structured training programs to standardize teaching, training, and safe expansion will aid the safe spread of the TaTME. PMID- 29588811 TI - Effect of low dose aspirin and dipyridamole on primary patency of arteriovenous grafts in hemodialysis patients: a randomized double-blind placebo-controlled trial. AB - Background: There is some evidence for the efficacy of antiplatelet therapies in increasing the vascular access patency duration or decreasing the thrombosis of arteriovenous grafts. Objective: To determine the effect of low dose aspirin and dipyridamole on primary patency of arteriovenous grafts in hemodialysis patients. Methods: This randomized, double-blind, placebo-controlled trial was done at Imam Reza Hospital in Mashhad, Iran from September 10, 2015 to July 05, 2016. Sixty hemodialysis patients, after the placement of a new arteriovenous graft, were divided into three study groups which including; Group 1, who received 80 mg aspirin tablet daily, Group 2 received 80 mg aspirin plus 75 mg dipyridamole daily and Group 3 received placebo daily. Primary unassisted patency was recorded in follow-up until 12 months and the outcomes were analysed using one-way ANOVA test. Results: Primary patency time in Group 1 (Aspirin) was 324.75+/-147.00 day and for Group 2 (Aspirin + Dipyridamole) was 399.05+/-92.09 day and for Group 3 (Placebo) was 383.55+/-108.23 day. There were no significant differences between the 3 groups (p>0.05). Successful dialysis was done in 16.7% in Group 1, 37.5% in Group 2 and 45% in Group 3 from brachial arteriovenous grafts after 1-year follow up (p=0.746). Conclusions: In treating dialysis patients, treatment with low dose aspirin and dipyridamole is not effective on increasing the synthetic grafts primary patency duration. Trial registration: The trial was registered at the Thai Clinical Trials Registry (http://www.clinicaltrials.in.th) with the Trct id: TCTR20160920003.

AB - Background: The topic of food safety has become a major public health issue worldwide. Over recent decades, the growing concern for food safety has brought about greater research regarding the risks associated with the consumption of produce that has been contaminated by pesticides, heavy metals and/or toxins. Objective: The study was conducted to determine the concentration of Pb in the muscle of buffalos slaughtered in the northwest regions of Iran (Ardabil, Urmia and Tabriz cities). Methods: The present was a descriptive cross-sectional study in the northwest regions of Iran during 2013 to 2014. A total of 30 muscle samples from individual buffalos were analyzed for Pb concentrations using Atomic Absorption Spectrophotometer (ASS). Statistical analysis was performed using SPSS 17.0. All results were computed as mean standard deviation and subjected to one way analysis of variance to establish whether the differences in Pb concentrations in meat samples from different cities were significant or not. The Statistical significance was determined at p<0.05. Results: The results showed that the mean concentration of Pb in muscle samples were measured 0.043+/-0.035 ppm. The highest Pb concentration (0.11 ppm) was detected in the buffalo muscle samples from Urmia city. In total, 25 muscle samples (80.33%) were contaminated with Pb and concentration of Pb in 3.33% of contaminated samples exceeded the permissible limits advised by the European Commission (EC) (0.1 ppm). Conclusion: We recommend identifying Pb sources in order to eliminate or control Pb contamination of food, and monitor environmental exposures and hazards to prevent lead poisoning. PMID- 29588814 TI - Environmental interventions based on the Health Belief Model and the Ecological social model in the continuation of consumption of rice, free from toxic metals. AB - Background and aim: Continuation of healthy nutritional behaviors is one of the important factors in effectiveness of educational intervention programs. The aim of this research is to compare the Health Belief Model and the Ecological-social model in reducing consumption of rice contaminated with toxic metals after completion of environmental intervention and continuation of consumption of healthy rice. Methods: This research was the implementation of a six-month randomized controlled trial interventional program in two groups' interventions along with a control group, with 80 people for each group totally, amounting to 240 women, between 18 and 50 years of age in Ilam, Iran in 2014. The questionnaires of the three groups consisted of demographic information, knowledge, the constructs of the models, performance of rice consumption. Friedman test and repeated measures used for data analysis with SPSS (version 20), and confidence interval of 95% were considered. Results: The results of the Friedman test indicated a significant increase in the number of women consuming healthy rice over six months after intervention in both intervention groups (p<0.001). Women in the ECO group consumed healthy rice 27.5% more than the HBM group (p<0.001). The results of repeated measures analysis of variance suggested greater improvement in the consumption of healthy rice in the ECO group in comparison with the HBM group over six months after intervention (p<0.05). Conclusions: Both educational environmental intervention methods caused the altered diet of people regarding consumption of healthy rice over six months after the intervention. Increased social support also probably had a more effective role in continuation of healthy diet among the people. PMID- 29588815 TI - Students' attitudes towards impact of the health department website on their health literacy in Semnan University of Medical Sciences.

Relationship between the study subjects' demographic characteristics and their attitudes was significant (p<0.05). Conclusion: This study showed that interventional strategies are necessary to lead students to make effective use of the university's health department website. Hence, the results of this study showed that the website of the health department needs to be redesigned, and this design would allow a better link between the University of Medical Sciences and its audience to promote health literacy. PMID- 29588816 TI - Designing and psychoanalysis: A comprehensive questionnaire on coping with domestic violence against women in Iranian society. AB - Background: Domestic violence is the third sociopathology after addiction and child abuse in Iran. Fifty-six percent of Iranian women in the range of 17-32 years old are exposed to the highest domestic violence. Objective: The aim of this study was to design and psychoanalyze a comprehensive questionnaire on coping with domestic violence against women in Iranian society. Methods: This study was carried out on a random sample of women exposed to domestic violence and referred to the health and care center of Shahid Beheshti University of Medical Sciences in Tehran, and Forensic Medical Centers in Urmia city (Iran), in 2017. Two hundred questionnaires were distributed among the participants. One hundred sixty-eight questionnaires were returned to the researchers for data analysis. Eight of those were excluded from the analysis because of incompleteness. Finally, exploratory factor analysis was performed. Results: After reviewing the literature, a questionnaire with 32 items was developed. Content validity ratio (0.95) and content validity index (0.97) were obtained. The results of exploratory factor analysis indicated that the questionnaire explained 69.34% of the data variance. Cronbach's alpha coefficient, and test retest methods were used for determining the reliability and the obtained value, which were 0.82 and 0.81, respectively. Conclusion: Validity and reliability of the questionnaire with 32 items were confirmed. The tool can be utilized to measure how women cope with domestic violence. PMID- 29588817 TI - Social media; resolving tunnel vision in practicing medicine. AB - Background: With the emergence of social media, physicians who use social media, including emergency medicine physicians, have shared their experiences with their colleagues instead of working alone and keeping their experiences to themselves. Objective: This study aimed to evaluate the rate and type of use of electronic online sources and social media, in order to improve learning and education among emergency medicine residents. Methods: This was a cross-sectional study carried out from September 2015 until August 2016 on emergency medicine residents of two main medical universities of Tehran, Iran. A questionnaire was prepared by reviewing the existing studies and asking emergency medicine professors inside and outside Iran for opinions. Census sampling method was applied and all emergency medicine residents were included. The gathered data were analyzed using statistical tests of chi square, Independent-samples t-test and Pearson's correlation coefficient via SPSS version 21. Results: Seventy three residents with the mean age of 34.2+/-5.2 years participated in this study (60.3% female). Smart phone is the most important tool they use for connecting to the Internet. About 30% use the Internet for about 1-2 hours a day. In half of these participants less than 25% of this time is spent on something related to their academic field of study. The correlation of sex (p=0.034) and age (p=0.049) with extent of using social media related to the academic field of study were significant. Other analytical analyses were not statistically significant (p>0.05). Conclusion: In summary, the findings of current study showed that despite sufficient access to proper technology, use of social media and online sources by high majority of the studied EM residents regarding improvement of their learning and educational level is very limited. PMID- 29588818 TI - A study of the diagnostic value of Inhibin A Tests for occurrence of preeclampsia in pregnant women. AB - Background: Hypertensive disorders are common during pregnancy, and are among 3 important causes of maternal death. Preeclampsia occurs in 3 to 5% of pregnancies. Early diagnosis of this disorder can lead to better pregnancy outcomes. Objective: The aim of this study was to determine the relationship between inhibin A serum levels during second stage pregnancy screening tests, and incidence and severity of preeclampsia. Methods: In this study, 300 pregnant women who referred to Kowsar Hospital and carried out second stage pregnancy screening tests from September 2014 to March 2015 in Urmia city, Iran, were enrolled. Five ml venous blood samples were obtained from each participant, and inhibin A serum levels were evaluated in all cases. Finally, all the necessary information was obtained from the pregnancy files of participants after delivery, and gathered in a questionnaire. The data were analyzed using SPSS software version 18 and independent t-test, ANOVA and descriptive statistics were used. P values less than 0.05 were considered significant. Results: Among the 300 pregnant women who were studied, the gestational age at the time of acquiring blood samples was as follows: 169 cases (56.3%) at 16-17 weeks, 77 cases (25.7%) at 18-19 weeks and 14 cases at 20 weeks (4.7%). In this study, MOM of inhibin A was more than 1.25 in 12 cases that finally, preeclampsia occurred in them. This relationship was statistically significant (p=0.001). The relationship between MOM of inhibin A and severe preeclampsia was evaluated, and the relationship was significant (p=0.004). The relationship between MOM of inhibin A and pregnancy hypertension was not significant (p=0.643). Conclusion: Considering the results of this study, we can conclude that MOM of inhibin A levels in maternal serum during second stage pregnancy screening tests can predict incidence and severity of developing preeclampsia in pregnant women. This is not true in cases of pregnancy hypertension. PMID- 29588819 TI - An agent based architecture for high-risk neonate management at neonatal intensive care unit. AB - Background: In recent years, the use of new tools and technologies has decreased the neonatal mortality rate. Despite the positive effect of using these technologies, the decisions are complex and uncertain in critical conditions when the neonate is preterm or has a low birth weight or malformations. There is a need to automate the high-risk neonate management process by creating real-time and more precise decision support tools. Objective: To create a collaborative and real-time environment to manage neonates with critical conditions at the NICU (Neonatal Intensive Care Unit) and to overcome high-risk neonate management weaknesses by applying a multi agent based analysis and design methodology as a new solution for NICU management. Methods: This study was a basic research for medical informatics method development that was carried out in 2017. The requirement analysis was done by reviewing articles on NICU Decision Support Systems. PubMed, Science Direct, and IEEE databases were searched. Only English articles published after 1990 were included; also, a needs assessment was done by reviewing the extracted features and current processes at the NICU environment where the research was conducted. We analyzed the requirements and identified the main system roles (agents) and interactions by a comparative study of existing NICU decision support systems. The Universal Multi Agent Platform (UMAP) was applied to implement a prototype of our multi agent based high-risk neonate management architecture. Results: Local environment agents interacted inside a container and each container interacted with external resources, including other NICU systems and consultation centers. In the NICU container, the main identified agents were reception, monitoring, NICU registry, and outcome prediction, which interacted with human agents including nurses and physicians. Conclusion: Managing patients at the NICU units requires online data collection, real-time collaboration, and management of many components. Multi agent systems are applied as a well-known solution for management, coordination, modeling, and control of NICU processes. We are currently working on an outcome prediction module using artificial intelligence techniques for neonatal mortality risk prediction. The full implementation of the proposed architecture and evaluation is considered the future work. PMID- 29588820 TI - Determinant of successful implementation of Computerized Provider Order Entry (CPOE) system from physicians' perspective: Feasibility study prior to implementation. AB - Background: Health information technology is a solution for medical error reduction through the implementation of Computerized Provider Order Entry (CPOE). Objective: The aim of this study was to determine physicians' attitudes toward the implementation of CPOE. Methods: This cross-sectional study was started in March 2017 and completed in June 2017. The study used a questionnaire to collect data from physicians in hospitals affiliated to Urmia University of Medical Sciences. We invited 200 physicians who were not using a CPOE system. Questionnaires were randomly distributed among physicians. In order to understand the physicians' attitude about implementation the CPOE system, we used the Diffusion of Innovation Theory, developed by E.M. Rogers. Data were analyzed by SPSS version 16.0, using descriptive statistics and one-way ANOVA. A p value <0.05 was considered to be statistically significant. Results: Most of the physicians were women (n=54, 60%) and the average age of the physicians was 36.39+/-8.42 years. About three-quarters of the physicians (76.66%) reported that they found the CPOE system adapted to their specific professional practice. The relative advantage of the CPOE system was estimated to be 42.22% for physicians and the complexity of that was 13.33%. There was no significant relationship between Compatibility, Relative advantages and Complexity with physicians' experience in HIS use and physicians' degree of education (p>0.05). Conclusion: Since the role of CPOE systems is very important in hospitals in order to reduce medication errors and to improve the quality of care, our results can be used to assist the planning and introduction of CPOE systems. PMID- 29588821 TI - Serum level of vitamin D in preterm infants and its association with premature related respiratory complications: a case-control study. AB - Background and aim: Prematurity and related problems, especially respiratory distress, are one of the main challenges for neonatal medicine. The aim of this study was to compare vitamin D levels in preterm infants with, and those without respiratory distress. Methods: This case-control study was conducted in Ghaem and Emam Reza Hospitals in Mashhad (Iran) from 2015 to 2016. In this study, we examined 160 preterm infants weighing less than 2000 grams and born at less than 34 weeks' gestation. Serum vitamin D levels were measured in preterm infants without- and those with respiratory distress, and their mothers. Neonatal characteristics, including age, sex, birth weight, gestational age, Apgar score and needs for oxygen, resuscitation, ventilation and surfactant were documented. The data were analyzed using SPSS version 16.0. Results: Means serum level of maternal vitamin D in control and case groups were 16.66+/-14.29 ng/dl and 21.23+/-15.19 ng/dl, respectively (p=0.029). In addition, mean serum level of neonatal vitamin D in control and case groups were 11.69+/-8.66 ng/dl 17.9+/ 12.55 ng/dl, respectively (p=0.001). Vitamin D levels in premature neonates without respiratory distress and their mothers were significantly different from other preterm neonates with respiratory distress (p=0.029). There was a direct correlation with neonatal and maternal vitamin D levels (r=0.713, p=0.001). The duration of hospitalization (p=0.001), gestational age (p=0.073), birth weight (p=0.001), one- and (p=0.001) five-minute (p=0.001) Apgar scores and head circumference (p=0.002) had significant relation with vitamin D levels in neonates. Death (12.5%) and pneumothorax (7.5%) were the main complications among cases with respiratory distress. Conclusion: According to the results of present research, neonatal vitamin D levels have a significant association with respiratory distress syndrome and maternal vitamin D levels. PMID- 29588822 TI - Candida albicans endophthalmitis following penetrating keratoplasty: A case report. AB - Endophthalmitis is one of the most serious complications of intraocular surgeries, and Candida albicans constitutes the majority of cases of post penetrating keratoplasty (PK) endophthalmitis. The presenting case is a 21-year old woman with known case of advanced keratoconus and vernal keratoconjunctivitis who underwent PK, and developed recalcitrant anterior uveitis and subsequent whitish lesion on the superonasal of the lens. She was on topical steroids with possible impression of Uretts Zavalia syndrome versus phacoantigenic uveitis following traumatic cataract up to the 50th day of post operation that manifested symptoms of frank endophthalmitis; and underwent deep vitrectomy, lensectomy, localized iridectomy and irrigation with diluted Imipenem and Amphotericin-B. Microbiologic study of a vitreous sample revealed growth of Candida albicans, however optisol culture was negative and donor rim was not evaluated. One week later, intravitreal Amphotericin-B was administered. The patient remained aphakic with clear graft in the 6th month follow up. Due to great correlation of positive donor rim culture with fungal endophthalmitis and the devastating effect of delayed diagnosis, routine donor rim culture is recommended, to aid us in earlier diagnosis in the presence of nonspecific early signs of fungal endophthalmitis. PMID- 29588823 TI - Histological evaluation of orthodontic tooth movement following low level laser irradiation in rabbits. AB - Background: Reduction of orthodontic treatment time is a major concern for orthodontists. Low level laser therapy (LLL) has been widely used in dentistry and it has been claimed that it could stimulate bone formation. Objective: The aim of the present study was to evaluate histological effects of LLL on alveolar bone remodeling during experimental tooth movement in rabbits. Methods: In this experimental study which was performed in the animal lab of Mashhad Dental School in 2016 twenty pre-pubertal female albino rabbits with the mean age of 8+/-1 weeks were randomly assigned into two groups. All the rabbits were examined by a veterinarian, and underweight or diseased rabbits were excluded from the study. Fifty gram orthodontic force was applied via 0.014 stainless steel spring on central teeth in both groups. In the first group, low level laser KLO3 (wave length: 980 nm, Power: 80mw) was irradiated three minutes from the buccal aspect of central teeth for 21 days. In the second group, rabbits were not exposed to laser irradiation and served as our control group. After this period, the distance between mesial corners of incisors was measured blindly by a caliper calibrated as 0.1mm. All rabbits in both groups were sacrificed by vital perfusion for histological evaluation to determine the number of resorption lacuna and amount of fibrous tissue. Independent sample t-test was used to analyze the data. Results: The number of resorption lacuna, the rate of tooth movement and fibrous tissue were significantly greater in the lased group (p=0.05). Conclusion: Low level laser irradiation could accelerate tooth movement in rabbits via increased resorptive activity in alveolar bone. PMID- 29588824 TI - The status and predictors of hypertension preventive nutritional behaviors in adolescents based on the constructs of the Theory of Planned Behavior. AB - Background: Malnutrition is an important factor affecting hypertensive incidence. Since the unhealthiest nutritional behaviors are rooted in childhood attitudes and experiences, applying educational interventions to these age groups will be most useful in the formation of preventive nutritional behaviors. Objective: To determine the predictive power of the TPB on hypertension in junior high-school students. Methods: The present cross-sectional study was conducted on 160 junior high-school students in Kashmar, Iran in academic year commencing 2-13-2014, selected through random sampling. The participants completed a researcher-made questionnaire consisting of a demographic information form and a section to evaluate the constructs of the TPB. The data collected were analyzed in SPSS-16 using the correlation Wilcoxon statistics test, the one-way ANOVA and multiple linear regression analysis. Results: The mean age of the students was 13.51. A total of 47% of the students had snacked on potato chips and cheese puffs, 45% had eaten high-fat foods and 51.2% had eaten cookies and chocolates within the past week. The variable of behavioral intention predicted 32% of the variations in preventive nutritional behaviors by itself. The Pearson product-moment correlation analysis found that hypertension preventive nutritional behaviors were significantly correlated with attitude (p<0.001, r=0.38), perceived behavioral control (p<0.001, r=0.38), and behavioral intention. Moreover, significant correlations were observed between subjective norms and attitude (p<0.028, r=0.173), perceived behavioral control and attitude (p<0.003, r=0.231), behavioral intention and attitude (p<0.001, r=0.370), behavioral intention and subjective norms (p<0.030, r=0.171) and between behavioral intention and perceived behavioral control (p<0.001, r=0.484). Conclusion: The examined students revealed an adequate adherence to preventive nutritional behaviors. Nutrition education interventions should be developed based on variables such as behavioral intention and its determinants, i.e. attitude, perceived behavioral control and subjective norms. PMID- 29588825 TI - The impact of general health and social support on health promoting lifestyle in the first year postpartum: the structural equation modelling. AB - Background and aim: Postpartum is a critical period for mothers which often leads to neglect of their own health. Mothers' new responsibilities may affect their health promoting lifestyle (HPL). The aim of this study was to determine the impact of both general health and social support on health-promoting lifestyle. Methods: A cross-sectional survey was conducted on 310 women who gave birth over a one-year period in Zanjan (Iran), 2016. A proportionate stratified random sampling technique was used to select respondents from each stratum. Health promoting lifestyle was assessed using the health-promoting lifestyle profile II (HPLP II) scale. A structure equation model (SEM) was used to determine the relationship between observed and latent variables. Data were analysed using SPSS version 22 and LISREL 8.5 software. Results: The age of 42.6% of the participants was more than 30 years and 40.3% of them had an academic education. The mean score of the health-promoting lifestyle was 131.28 (15.37). The structural equation model fitted well with RMSEA =0.07, CFI=0.92, and GFI=0.94. Among the latent factors, general health, with a factor load of -0.68, had greater impact on health-promoting lifestyle than social support. Moreover, there was a significant correlation (-0.63) between general health and perceived social support in the postpartum period. Conclusion: health-promoting lifestyle was not at appropriate levels among women in the first year after delivery. These findings suggest that strengthening general health and social support would improve a health-promoting lifestyle in Iranian postpartum women. PMID- 29588826 TI - Relationship between behavioral indices of pain during labor pain with pain intensity and duration of delivery. AB - Background: Certain behaviors can be adopted by women to cope with labor pain according to their individual characteristics, which are currently called behavioral indicators during labor pain, and include facial expressions, verbal expressions, tone of voice, body movements, degree of relaxation, and respiratory system functioning during delivery. Moreover, severity of pain and duration of labor can vary due to several factors including individual characteristics. Objective: The purpose of the present study was to determine the relationship between behavioral indicators during labor pain, severity of pain, and delivery duration. Methods: In this cross-sectional study, 120 low risk pregnant women who referred to Omolbanin (AS) Hospital in the city of Mashhad (Iran) for delivery in 2014, were selected via convenience sampling method, which was then followed by completion of demographic information forms. From cervical dilatation of 3-5 centimeters until delivery, the Labor Pain Coping Behavior Observation Form (comprised of 6 sub-groups of facial expressions, verbal expressions, tone of voice, body movements, degree of relaxation, and respiratory function and severity and duration of pain) was completed during uterine contractions and every half an hour. Using the Inventory of Labor Information; vital signs, frequency of contractions, and duration of the first and second stages of labor were measured. Furthermore, the content validity of the questionnaire was determined and its reliability was confirmed by Cronbach's alpha method. Then, the data were analyzed using the SPSS version 16, through Pearson Product-Moment Correlation and Spearman's Rank-Order Correlation, Kruskal-Wallis test, and ANOVA. Results: According to the results, 16.2% of the individuals had undesirable behavioral indicators during labor pain, 50% of them were endowed with acceptable behaviors, and 33.8% of these women had desirable behaviors. The findings also revealed that the duration of the active phase of the first stage of labor (p<0.001 and r=-0.453), the duration of the second stage of labor (p<0.012 and r=-0.146), and the severity of pain (p<0.001 and r=-0.450) were significantly and inversely correlated with behavioral indicators during labor pain; i.e. an increase in the mean score of behavioral indicators during labor pain could lead to a decline in the duration of stages of labor and severity of pain. Conclusion: It was concluded that behaviors demonstrated by women in labor had effects on their pains in the course of delivery, and there was also a relationship between the duration of stages of labor and its severity of pain. Therefore, it was recommended to turn attention to behaviors by women in labor in order to achieve a desirable clinical management. PMID- 29588827 TI - Genetic association of liver X receptor beta rs2695121 polymorphism with obesity related traits in a northeastern Iranian population. AB - Background: Liver X receptor Beta (LXRbeta), located in an obesity susceptible region, has been shown to be involved in the metabolism of lipid and carbohydrates. Previous human genetic studies have suggested genetic variability of LXRbeta could be associated with human obesity. Therefore, we hypothesized that LXRbeta gene rs2695121 polymorphism may be associated with the risk of obesity in a northeastern Iranian population. Methods: A TaqMan allelic discrimination assay was used to genotype LXRbeta rs2695121 polymorphism in this cross-sectional study of 168 obese, 209 overweight and 76 normal-weight subjects recruited from Mashhad city in Iran. Logistic regression analyses were used to analyze alleles and genotypes distribution. Anthropometrics and clinical variables among different genotype carriers were compared by univariate analyses. All statistical analysis was performed using SPSS v.16.0. Results: Allelic and genotypic associations with obesity were not significant for the rs2695121 variant even after adjustment for age and gender (OR=1.17, 95% CI=0.46-2.91), p=0.586). Moreover, haplotype analysis using data from the other variant (rs17373080) of LXRbeta revealed no significant association (p=0.88). However, among the clinical and metabolic parameters tested, systolic and diastolic blood pressures were found nominally associated with the genotype CT (p=0.031 and p=0.017 respectively). Conclusion: This study failed to demonstrate any association between the rs2695121 variant of LXRbeta and obesity neither alone nor when considered with rs17373080. However, its association with blood pressure may influence one's susceptibility to obesity, supporting further studies in a larger population.

AB - Background and aim: Post-operative self-care behaviors, have positive effects on increase in adaptability, and reduce cardiac surgery patients' disability. The present study is carried out aimed at determining the effect of education based on a health promotion model on the patients' self-care behaviors after coronary artery bypass surgery. Methods: This is a semi-experimental study carried out in Mazandaran (Iran) in 2016. Two hundred and twenty patients who participated in the study were selected using a simple random sampling method from a population of postoperative patients, and divided into control and experimental groups (110 patients in each) using block (AABB) randomization. Self-designed self-care questionnaires based on a health promotion model were distributed among the patients once before and three months after intervention. The data were analyzed by SPSS-22, Chi-Square tests, Mann-Whitney and ANCOVA at the significance level of p<0.05. Results: The average score of total self-care behaviors in cardiac surgery patients was not significant between the two groups before education (p=0.065), but after training, a significant difference was observed between the two groups (p<0.001). The analysis of ANOVA with repeated measure indicated that following the intervention, significant difference was observed between the two groups in terms of improvement of self-care behaviors after excluding the effect of pre-test and controlling demographic and health-related characteristics. Conclusions: Developing and implementing a training program based on the health promotion model can enhance self-care behaviors and reduce the number of admissions in patients after cardiac surgery. PMID- 29588829 TI - The effectiveness of clinical teaching of mental health courses in nursing using clinical supervision and Kirkpatrick's model. AB - Background: Clinical experience associated with the fear and anxiety of nursing students in the psychiatric unit. Mental health nursing instructors find it challenging to teach nursing students to deal with patients with mental disorders in an environment where they need to provide patient teaching and clinical decision-making based on evidence and new technology. Objective: To measure the effectiveness of clinical teaching of mental health courses in nursing using clinical supervision and Kirkpatrick's model evaluation in the psychiatry unit of Imam Reza Hospital, Bojnurd, Iran. Methods: This cross-sectional study was carried out from 2011 to 2016 on 76 nursing students from a university as part of a clinical mental health course in two semesters. The students were selected by a non-probable convenient sampling method. After completing their clinical education, each student responded to checklist questions based on the four-level Kirkpatrick's model evaluation and open questions relating to clinical supervision. Finally, all data was analyzed using the SPSS version 16. Results: The students have evaluated clinical supervision as a useful approach, and appreciated the instructor's supportive behavior during teaching and imparting clinical skills. This has made them feel relaxed at the end of the clinical teaching course. In addition, in the evaluation through Kirkpatrick's model, more than 70% of the students have been satisfied with the method of conducting the teaching and average score of nursing students' attitude toward mental health students: Their mean self-confidence score was 18.33+/-1.69, and the mean score of their performance in the study was evaluated to be 93.74+/-5.3 from 100 points. Conclusion: The results of clinical mental health teaching through clinical supervision and Kirkpatrick's model evaluation show that the satisfaction, self-esteem, attitude, and skill of nursing students are excellent, thereby portraying the effectiveness of clinical teaching. But this program still needs to be reformed. To establish long-term goals and obtain knowledge and clinical skills of nursing, it is recommended to develop a curriculum and evaluate it appropriately. PMID- 29588830 TI - Allergic bronchopulmonary aspergillosis in patients with cystic fibrosis and non cystic fibrosis bronchiectasis. AB - Background: Aspergillus sensitization (AS) and allergic bronchopulmonary aspergillosis (ABPA) can occur as a cause of permanent lung damage in patients with cystic fibrosis (CF) and non-CF bronchiectasis. Objective: The aim of this study was to determine the frequency of AS and ABPA in patients with CF and non CF bronchiectasis in southwestern Iran. Methods: This cross-sectional study was conducted on 33 patients with CF and 27 patients with non-CF bronchiectasis from southwestern Iran who were referred to Namazi Hospital affiliated to Shiraz University of Medical Sciences from July 2015 to February 2016. Skin prick test to Aspergillus fumigatus, peripheral blood eosinophil count, total serum IgE, specific IgE and IgG against Aspergillus fumigatus as well as radiologic chest studies were done for each patient. Statistical analysis was done by Mann-Whitney U test, Fisher Exact test, and Kappa weighted in SPSS software version 18. Level of significance was set at p<0.05. Results: Nine patients with CF (27.3%) and one patient with non-CF bronchiectasis (3.7%) had positive skin tests to Aspergillus. There was 81.2% agreement between positive skin test and specific IgE to Aspergillus fumigatus (p<0.001). Three patients with CF (9%) met the diagnostic criteria for ABPA, whereas ABPA was not seen in patients with non-CF bronchiectasis. Conclusion: ABPA was low in this study, considering more frequency of AS in patients with cystic fibrosis, clinicians should keep in mind the diagnosis of ABPA for those CF patients that do not respond to usual medical therapy and have positive skin tests to Aspergillus allergens.

PMID- 29588831 TI - Analysis of the expression pattern of the schizophrenia-risk and intellectual disability gene TCF4 in the developing and adult brain suggests a role in development and plasticity of cortical and hippocampal neurons. AB - Background: Haploinsufficiency of the class I bHLH transcription factor TCF4 causes Pitt-Hopkins syndrome (PTHS), a severe neurodevelopmental disorder, while common variants in the TCF4 gene have been identified as susceptibility factors for schizophrenia. It remains largely unknown, which brain regions are dependent on TCF4 for their development and function. Methods: We systematically analyzed the expression pattern of TCF4 in the developing and adult mouse brain. We used immunofluorescent staining to identify candidate regions whose development and function depend on TCF4. In addition, we determined TCF4 expression in the developing rhesus monkey brain and in the developing and adult human brain through analysis of transcriptomic datasets and compared the expression pattern between species. Finally, we morphometrically and histologically analyzed selected brain structures in Tcf4-haploinsufficient mice and compared our morphometric findings to neuroanatomical findings in PTHS patients. Results: TCF4 is broadly expressed in cortical and subcortical structures in the developing and adult mouse brain. The TCF4 expression pattern was highly similar between humans, rhesus monkeys, and mice. Moreover, Tcf4 haploinsufficiency in mice replicated structural brain anomalies observed in PTHS patients. Conclusion: Our data suggests that TCF4 is involved in the development and function of multiple brain regions and indicates that its regulation is evolutionary conserved. Moreover, our data validate Tcf4-haploinsufficient mice as a model to study the neurodevelopmental basis of PTHS. PMID- 29588835 TI - Challenging current views on bile acid diarrhoea and malabsorption. AB - Background: In 2012, the National Institute for Health and Care Excellence (NICE) assessed guidance (DG7) on the use of tauroselcholic (75selenium) acid (also known as SeHCAT) for the investigation of diarrhoea due to bile acid malabsorption (BAM) in patients with IBS-D and in patients with Crohn's disease who have not had an ileal resection. NICE concluded that tauroselcholic (75selenium) acid was recommended for use in research only. NICE will be reviewing the decision to update the guidance for tauroselcholic (75selenium) acid, for these populations, in March 2017. Aim: Our aim is to summarise advances in BAM, also known as bile acid diarrhoea (BAD), and encourage clinicians to re evaluate their understanding of this disorder. Approach: We review the prevalence, diagnosis and treatment of BAD/BAM. We describe the new evidence available since the original NICE review in 2012, and discuss the economic issues associated with failure to diagnose or to treat BAD/BAM accurately. Evidence update: There is new and compelling evidence available since DG7, which shows that tauroselcholic (75selenium) acid scanning is a powerful tool in the diagnosis of BAD/BAM. We summarise published prevalence data (approximately 1% prevalence in the UK, as suggested by clinical practice diagnosis rates), and highlight that the true prevalence of BAD/BAM could be far greater than this. Conclusion: We present evidence that challenges current opinion about this disorder, and we commend both clinicians and health technology assessment (HTA) agencies for being open to arguments and new evidence in any future HTAs. PMID- 29588834 TI - Practical guidance on the use of faecal calprotectin. AB - Differentiation between inflammatory bowel disease (IBD) and functional gut disorders, and the determination of mucosal disease activity in established cases of IBD remain the cornerstones of disease diagnosis and management. Non-invasive, accurate biomarkers of gut inflammation are needed due to the variability of symptoms, the inaccuracies of currently available blood markers and the cost and invasive nature of endoscopy. Numerous biomarkers have been used and/or considered with some in current use. This article reviews the current evidence base around the indications for using biomarkers and their limitations, with a particular focus on faecal calprotectin. PMID- 29588836 TI - Emerging role of thalidomide in the treatment of gastrointestinal bleeding. AB - Thalidomide was initially synthesised in 1954 and marketed as a sedative and antiemetic for morning sickness. It was withdrawn in 1961 due to the realisation that it was teratogenic with over 10 000 children born with congenital abnormalities. Since then it has been used for treatment of dermatological and oncological conditions, including myeloma. In 1994, it was found to have a potent antiangiogenic effect via downregulation of vascular endothelial growth factor (VEGF). This has led to its use in gastrointestinal bleeding, as vascular abnormalities such as angiodysplasia have been found to have elevated VEGF levels. This article will review the current evidence of the use of thalidomide in bleeding associated with gastrointestinal vascular malformations, including angiodysplasia, gastric cancer and radiation-induced proctitis. PMID- 29588837 TI - Nasal unsedated seated percutaneous endoscopic gastrostomy (nuPEG): a safe and effective technique for percutaneous endoscopic gastrostomy placement in high risk candidates. AB - Objective: Percutaneous endoscopic gastrostomy (PEG) tube placement is associated with a high risk of cardiorespiratory complications in patients with significant respiratory compromise. This study reports a case series of high-risk patients undergoing PEG placement using a modified technique-nasal unsedated seated PEG (nuPEG) placement. Design: Retrospective review of 67 patients at high risk of complications undergoing PEG placement between September 2012 and December 2016. Setting: UK specialist tertiary centre for clinical nutrition support. Interventions: Patients underwent 'push' PEG placement using nasal endoscopy without sedation in a seated position. Main outcome measures: Procedural success and tolerability, short term (within 24 hours), medium term (24 hours to 30 days) complications and survival were recorded. Results: 67 patients underwent 68 nuPEG placements. The majority had motor neuron disease (46/67). One patient developed a lower respiratory tract infection the following day. Two patients experienced accidental displacement of their PEG within 2 weeks. One patient died within 30 days of nuPEG insertion due to reasons unrelated to the procedure. Endoscopic comfort scores of 1 or 2 (98.0%) indicated good tolerance. A failure rate of 10.5% was attributed to intrathoracic displacement of the stomach, almost certainly due to the advanced stage of the neurological disease and associated diaphragmatic weakness. Conclusions: Our experience with the nuPEG technique suggests that it is safe and well tolerated in high-risk patients. As a result, it has now entirely supplanted radiologically inserted gastrostomy insertion in our institution and we recommend it as the method of choice for gastrostomy tube insertion in such patients. PMID- 29588838 TI - The clinical management of hereditary haemochromatosis. AB - Hereditary haemochromatosis is an autosomal recessive disorder with variable penetrance. Most patients are C282Y homozygotes while heterozygotes or patients who are homozygous with other mutations are uncommonly affected. The true genotype to phenotype expression remains unclear. Treatment with phlebotomy is highly effective and cost-efficient while liver transplantation confers a curative option. PMID- 29588839 TI - Non-invasive markers of liver fibrosis in fatty liver disease are unreliable in people of South Asian descent. AB - Objective: Liver biopsy is the most accurate method for determining stage and grade of injury in non-alcoholic fatty liver disease (NAFLD). Given risks and limitations of biopsy, non-invasive tests such as NAFLD fibrosis score, aspartate transaminase (AST) to platelet ratio index, Fib-4, AST/alanine transaminase ratio and BARD are used. Prevalence and severity of NAFLD and metabolic syndrome vary by ethnicity, yet tests have been developed in largely white populations. We tested our hypothesis that non-invasive tests that include metabolic parameters are less accurate in South Asian compared with white patients. Design: Retrospective cross-sectional. Setting: Specialist liver centre. Patients: Patients with histologically confirmed NAFLD. Interventions: Scores calculated using clinical data taken within 1 week and compared with histology (Kleiner). Main outcome measures: Diagnostic test characteristics. Results: 175 patients were identified. South Asians (n=90) were younger, had lower body mass index and lower proportion of obesity compared with white patients (n=79), with comparable rates of diabetes and liver injury. Tests are less sensitive at detecting advanced fibrosis in South Asian compared with white patients. Relative risk of correct diagnosis in white patients compared with South Asians is 1.86 (95% CI 1.4 to 2.6). In binary logistic regression models, ethnicity and platelet count predicted accuracy. Transient elastography was equally and highly accurate in both ethnicities. Conclusions: Blood test-based non-invasive scores are less accurate in South Asian patients, irrespective of metabolic parameters. Ethnicity should be considered when devising risk-stratification algorithms for NAFLD. PMID- 29588840 TI - Device-assisted enteroscopy in the UK: description of a large tertiary case series under conscious sedation. AB - Objective: Device-assisted enteroscopy (DAE) has developed rapidly, particularly with the advent of double-balloon enteroscopy (DBE). This study reports a case series from a UK tertiary centre for DAE across two modalities-DBE and spiral enteroscopy (SE)-under conscious sedation. Design: Retrospective observational study of 257 enteroscopy procedures from 2008 to 2014. Data were collected on demographics, indications, diagnosis, sedation requirements, duration, complications, tolerance, therapy performed and completion rate. Procedures were performed under conscious sedation using a combination of midazolam, pethidine and fentanyl in a solely outpatient setting. Results: Obscure gastrointestinal bleeding (OGIB) was the commonest indication for DAE (n=164, 63.8%). Overall, yield of DAE was 47.2% and varied significantly across the indications (p=0.003). There was a greater likelihood of positive findings if the indication was polyposis syndrome (75%), abnormal capsule endoscopy (67%) or OGIB (53%) and in older patients (mean age normal exam 60.3 vs abnormal exam 67.9 years, p<0.001). Higher mean doses of midazolam were used for DBE from above (5.4 mg, SD 2.24) and SE (5.6 mg, SD 2.9) to DBE from below (4.4 mg, SD 1.8). No serious complications were recorded. Tolerance of DAE was good with the majority (240/257, 93.4%) of procedures tolerated with comfort scores 0 or 1. Therapy was performed in 121/257 (47.1%) of procedures. The strongest predictor indications for therapy to be performed at DAE were abnormal capsule endoscopy (88.9%) and occult gastrointestinal (GI) bleeding (54.9%). Completion rates were higher in DBEb (91.8%) compared to DBEa (76.5%) and SE (81.6%). Conclusion: DAE under conscious sedation is safe and well tolerated. DAE has a high yield if performed for recognised indications and may be safely used to provide therapy where a diagnosis has been made using other modalities. PMID- 29588841 TI - Non-technical skills and gastrointestinal endoscopy: a review of the literature. AB - Background: Non-technical skills (NTS) have gained increasing recognition in recent years for their role in safe, effective team performance in healthcare. Gastrointestinal endoscopy is a procedure-based specialty with rapidly advancing technology, significant operational pressures and rapidly changing 'teams of experts'. However, to date there has been little focus on the effect of NTS in this field. Objectives: This review aims to examine the existing literature on NTS in gastrointestinal endoscopy and identify areas for further research. Method: A systematic search of MEDLINE, Embase, Cochrane Library, PsychINFO, CINAHL Plus and PubMed databases was performed using search terms Non-Technical Skills, Team Performance or Team Skills, and Endoscopy, Colonoscopy, OGD, Gastroscopy, Endoscopic Retrograde Cholangio-Pancreatography or Endoscopic Ultrasound. Results: Eighteen relevant publications were found. NTS are deemed an essential component of practice, but so far there is little evidence of their integration into training or competency assessment. Those studies examining the effects of NTS and team training in endoscopy are small and have variable outcome measures with limited evidence of improvement in skills or clinical outcomes. NTS assessment in endoscopy is in its early phases with a few tools in development. Conclusions: The current literature on NTS in gastrointestinal endoscopy is limited. NTS, however, are deemed an essential component of practice, with potential positive effects on team performance and clinical outcomes. A validated reliable tool would enable evaluation of training and investigation into the effects of NTS on outcomes. There is a clear need for further research in this field. PMID- 29588842 TI - Factors associated with the efficacy of polyp detection during routine flexible sigmoidoscopy. AB - Objective: Flexible sigmoidoscopy reduces the incidence of colonic cancer through the detection and removal of premalignant adenomas. However, the efficacy of the procedure is variable. The aim of the present study was to examine factors associated with the efficacy of detecting polyps during flexible sigmoidoscopy. Design and patients: Retrospective observational cohort study of all individuals undergoing routine flexible sigmoidoscopy in NHS Greater Glasgow and Clyde from January 2013 to January 2016. Results: A total of 7713 patients were included. Median age was 52 years and 50% were male. Polyps were detected in 1172 (13%) patients. On multivariate analysis, increasing age (OR 1.020 (1.016-1.023) p<0.001), male sex (OR 1.23 (1.10-1.38) p<0.001) and the use of any bowel preparation (OR 3.55 (1.47-8.57) p<0.001) were associated with increasing numbers of polyps being detected. There was no significant difference in the number of polyps found in patients who had received an oral laxative preparation compared with an enema (OR 3.81 (1.57-9.22) vs 3.45 (1.43-8.34)), or in those who received sedation versus those who had not (OR 1.00 vs 1.04 (0.91-1.17) p=0.591). Furthermore, the highest number of polyps was found when the sigmoidoscope was inserted to the descending colon (OR 1.30 (1.04-1.63)). Conclusions: Increasing age, male sex and the utilisation of any bowel preparation were associated with an increased polyp detection rate. However, the use of sedation or oral laxative preparation appears to confer no additional benefit. In addition, the results indicate that insertion to the descending colon optimises the efficacy of flexible sigmoidoscopy polyp detection. PMID- 29588843 TI - Protracted severe systemic cytomegalovirus disease in an immunosuppressed patient with ulcerative colitis. AB - A 33-year-old man with ulcerative colitis presented with 5-day history of fever, night sweats, abdominal pain and increased stool frequency. He was on mesalazine M/R 1 g once daily, 6-mercaptopurine (6-MP) 75 mg once daily and prednisolone 40 mg once daily. Examination revealed fever and tachycardia. Blood examinations identified a persistent leucopenia, C reactive protein of 23 mg/L and an initial alanine transaminase of 855 IU/L. Flexible sigmoidoscopy revealed well demarcated, punched-out ulcers in the proximal rectum and distal sigmoid, with histology pathognomonic of cytomegalovirus (CMV). CMV DNA PCR was 51 140 copies/mL. Despite prompt withdrawal of 6-MP, steroids and initiation of intravenous ganciclovir on day 2 of admission, his systemic illness, diarrhoea and fever persisted until day 19 of antiviral therapy. Other copathogens and lymphoma were ruled out on serology and CT scan, respectively. After an unusually prolonged course of antiviral therapy, the patient made a full clinical recovery, bloods normalised and there were two consecutive undetectable CMV DNA PCRs. PMID- 29588844 TI - Tacrolimus therapy in moderate to subacute ulcerative proctocolitis: a large single-centre cohort study. AB - Objective: To explore the 'real world' effectiveness of tacrolimus therapy for refractory ulcerative proctocolitis (UC). Design: Retrospective cohort study using prospectively collated clinical data. Setting: A single district general hospital in Kent, UK. Clinical decisions and regular monitoring were undertaken by a single expert in inflammatory bowel disease. Patients: All patients started on tacrolimus between January 2010 and August 2016 at Tunbridge Wells Hospital. Interventions: Following failure of conventional medication, tacrolimus was commenced at 0.5 mg/kg twice daily. Drug trough levels of 5-20 ng/mL were targeted. Other immunomodulation was stopped and steroids were weaned over 4-6 weeks. Main outcome measures: Treatment duration was measured for each patient. If the drug was stopped, the rationale, including specific side effects, was recorded. The patient's subsequent management plan was noted. Results: Thirty five patients were started on tacrolimus (range: 18-85, median: 36 years). Disease extent included proctitis to pancolitis. Twenty-five patients derived no benefit. Four patients responded, but drug side effects necessitated withdrawal. Eighteen of these 29 patients (62%) underwent surgery. One patient, who had previously responded, stopped the drug after becoming pregnant (healthy subsequent birth). Therefore, 5 of 35 patients (14%) remain on tacrolimus with sustained clinical response, ranging from 6 to 76 (median: 32) months of treatment. Treatment was most effective for proctosigmoiditis. There were no other demographic or biological markers for success. Conclusions: In line with UK and European guidelines, tacrolimus can be beneficial for refractory UC. With appropriate monitoring, it appears treatment can be continued safely long term. PMID- 29588845 TI - Pedunculated polyp of the ileum protruding from a large diverticulum. AB - Introduction: A 52-year-old woman presented with iron deficiency anaemia and postprandial right lower quadrant pain. Abdominal examination was unremarkable and laboratory results showed mild anaemia (haemoglobin 11.3 g/dL). Upper and lower endoscopies did not reveal any source of bleeding. Video capsule endoscopy was performed which showed a large polypoid lesion in the mid-ileum (figure 1). Abdominal contrast enhanced CT demonstrated a heterogeneously enhancing pedunculated polyp measuring approximately 6 cm (figure 2). Retrograde double balloon enteroscopy was performed which revealed a large pedunculated polyp with hyperplastic-like mucosa protruding from a large diverticulum located approximately 70 cm proximal to the ileocaecal valve (figure 3A). The stalk appeared to arise from the base of the diverticulum (figure 3B). A technetium-99m pertechnetate scintigraphy revealed no ectopic gastric mucosa.Figure 1Video capsule endoscopy shows a large polypoid lesion.Figure 2CT shows a heterogeneously enhancing pedunculated polyp (arrow).Figure 3Retrograde double balloon enteroscopy images.

PMID- 29588846 TI - Long-term follow-up of the use of maintenance antibiotic therapy for chronic antibiotic-dependent pouchitis. AB - Objective: Restorative proctolectomy is considered the procedure of choice in patients with ulcerative colitis who have failed medical therapy. Chronic pouchitis occurs in 10%-15% of patients, which often require long-term antibiotics to alleviate symptoms. Safety and efficacy of long-term maintenance antibiotics for chronic pouchitis has yet to be established. We aimed to assess the long-term safety and efficacy of maintenance antibiotic therapy for chronic pouchitis. Design: This was an observational study. We followed up patients who were diagnosed with chronic antibiotic-dependent pouchitis. Setting: Data were collected from our single specialist pouch centre. Patients: Patients with chronic antibiotic-dependent pouchitis who had been maintained on antibiotics continuously for at least 1 year with a least one follow-up visit. Main outcome measure: Development of pouch failure defined by the need for an ileostomy, patient-reported side effects of antibiotics and development of antibiotic resistance found on stool coliform testing. Results: Long-term use of antibiotics achieve remission in 21% of patients over a median follow-up of 102 (range 9 125). Pouch failure in association with chronic pouchitis after a median follow up of 8.5 years occurred in 18%. Side effects of long-term antibiotic use occurred in 28% of patients, with resistance to antibiotics from at least one stool sample occurring in 78% patients. Conclusions: Although the use of antibiotics in chronic pouchitis may be justified, the use of long-term antibiotics must be weighed against potential complications associated with pouchitis and antibiotics. PMID- 29588847 TI - Impact and cost-effectiveness of formal gastroenterology outpatient referral Clinical Assessment Service. AB - Objective: The aim was to assess the financial and operational impact of our new gastroenterology referral pathway model on our services. Design: An electronic 'Clinical Assessment Service' (CAS) proforma and an information platform were developed, and all data were analysed retrospectively. Setting: Royal Wolverhampton NHS Trust. Patients: 14 245 general practitioner (GP) referrals were received during January 2014-December 2016 with 9773 of them being triaged via our CAS. Main outcome measures: We looked into patients' clinical outcome along with departmental performance and finances. Results: A new outpatient appointment was offered to 60.1% (n=5873) of the CAS referred patients. Endoscopic or radiological investigations were requested for 29.2% (n=2854) of patients prior to deciding on further management plan. Out of those, 27% (n=765) went on to receive another gastroenterology (GI) clinic appointment. The remaining 21.3% (n=2089) of the CAS patients were discharged back to their GP following initial investigations. 5.5% (n=538) were discharged back to primary care with a letter of advice, whereas 5.2% (n=509) were deemed inappropriate for GI clinic and were redirected to other specialists. Overall, 32% (n=3127) of patients were managed without a face to face consultation in the GI clinic. This corresponds to 3136 less outpatient appointments with estimated reduced expenditure by the Clinical Commissioning Group (CCG) of L481K. The 18-week performance and waiting times remained stable despite the increasing referral population. The DNA rate dropped from 14% pre to 8.5%. Conclusions: Our clinical assessment model has, in addition to the clinical benefits, a considerable positive financial impact to the health economy.

PMID- 29588849 TI - Enhanced calcium ion mobilization in osteoblasts on amino group containing plasma polymer nanolayer. AB - Background: Biomaterial modifications-chemical and topographical-are of particular importance for the integration of materials in biosystems. Cells are known to sense these biomaterial characteristics, but it has remained unclear which physiological processes bio modifications trigger. Hence, the question arises of whether the dynamic of intracellular calcium ions is important for the characterization of the cell-material interaction. In our prior research we could demonstrate that a defined geometrical surface topography affects the cell physiology; this was finally detectable in a reduced intracellular calcium mobilization after the addition of adenosine triphosphate (ATP). Results: This new contribution examines the cell physiology of human osteoblasts concerning the relative cell viability and the calcium ion dynamic on different chemical modifications of silicon-titanium (Ti) substrates. Chemical modifications comprising the coating of Ti surfaces with a plasma polymerized allylamine (PPAAm)-layer or with a thin layer of collagen type-I were compared with a bare Ti substrate as well as tissue culture plastic. For this purpose, the human osteoblasts (MG-63 and primary osteoblasts) were seeded onto the surfaces for 24 h. The relative cell viability was determined by colorimetric measurements of the cell metabolism and relativized to the density of cells quantified using crystal violet staining. The calcium ion dynamic of osteoblasts was evaluated by the calcium imaging analysis of fluo-3 stained vital cells using a confocal laser scanning microscope. The positively charged nano PPAAm-layer resulted in enhanced intracellular calcium ion mobilization after ATP-stimulus and cell viability. This study underlines the importance of the calcium signaling for the manifestation of the cell physiology. Conclusions: Our current work provides new insights into the intracellular calcium dynamic caused by diverse chemical surface compositions. The calcium ion dynamic appears to be a sensitive parameter for the cell physiology and, thus, may represent a useful approach for evaluating a new biomaterial. In this regard, reliable in vitro-tests of cell behavior at the interface to a material are crucial steps in securing the success of a new biomaterial in medicine. PMID- 29588850 TI - TP53TG1 enhances cisplatin sensitivity of non-small cell lung cancer cells through regulating miR-18a/PTEN axis. AB - Background: The acquisition of drug resistance has been considered as a main obstacle for cancer chemotherapy. Tumor protein 53 target gene 1 (TP53TG1), a p53 induced lncRNA, plays a vital role in the progression of human cancers. However, little is known about the detailed function and molecular mechanism of TP53TG1 in cisplatin resistance of NSCLC. Methods: qRT-PCR analysis was used to detect the expression of TP53TG1, miR-18a and PTEN mRNA in NSCLC tissues and cells. Western blot analysis was performed to determine the protein level of PTEN and cleaved caspase-3. Cell viability and IC50 value were measured by MTT assay. Cell apoptosis was confirmed by flow cytometry assay. Subcellular fractionation assay was used to identify the subcellular location of TP53TG1. Dual-luciferase reporter assay, RNA pull down assay and RNA immunoprecipitation assay were carried out to verify the interaction between TP53TG1 and miR-18a. Xenografts in nude mice were established to verify the effect of TP53TG1 on cisplatin sensitivity of NSCLC cells in vivo. Results: TP53TG1 level was downregulated in NSCLC tissues and cell lines. Upregulated TP53TG1 enhanced cisplatin sensitivity and apoptosis of A549/DDP cells, while TP53TG1 depletion inhibited cisplatin sensitivity and apoptosis of A549 cells. TP53TG1 suppressed miR-18a expression in A549 cells. Moreover, TP53TG1-mediated enhancement effect on cisplatin sensitivity was abated following the restoration of miR-18a expression in A549/DDP cells, while si-TP53TG1-induced decrease of cisplatin sensitivity and apoptosis was counteracted by miR-18a inhibitor in A549 cells. Furthermore, TP53TG1 promoted PTEN expression via inhibiting miR-18a. Finally, TP53TG1 sensitized NSCLC cells to cisplatin in vivo. Conclusion: TP53TG1 increased the sensitivity of NSCLC cells to cisplatin by modulating miR-18a/PTEN axis, elucidating a novel approach to boost the effectiveness of chemotherapy for NSCLC. PMID- 29588851 TI - Vancomycin-resistant Enterococcus faecium sequence type 796 - rapid international dissemination of a new epidemic clone. AB - Background: Vancomycin-resistant Enterococcus faecium (VRE) is a leading cause of hospital-acquired infections. New, presumably better-adapted strains of VRE appear unpredictably; it is uncertain how they spread despite improved infection control. We aimed to investigate the relatedness of a novel sequence type (ST) of vanB E. faecium - ST796 - very near its time of origin from hospitals in three Australian states and New Zealand. Methods: Following near-simultaneous outbreaks of ST796 in multiple institutions, we gathered then tested colonization and bloodstream infection isolates' antimicrobial resistance (AMR) phenotypes, and phylogenomic relationships using whole genome sequencing (WGS). Patient meta-data was explored to trace the spread of ST796. Results: A novel clone of vanB E. faecium (ST796) was first detected at one Australian hospital in late 2011, then in two New Zealand hospitals linked by inter-hospital transfers from separate Melbourne hospitals. ST796 also appeared in hospitals in South Australia and New South Wales and was responsible for at least one major colonization outbreak in a Neonatal Intensive Care Unit without identifiable links between centers. No exceptional AMR was detected in the isolates. While WGS analysis showed very limited diversity at the core genome, consistent with recent emergence of the clone, clustering by institution was observed. Conclusions: Evolution of new E. faecium clones, followed by recognized or unrecognized movement of colonized individuals then rapid intra-institutional cross-transmission best explain the multi-center, multistate and international outbreak we observed. PMID- 29588852 TI - Treating refractory depression in Parkinson's disease: a meta-analysis of transcranial magnetic stimulation. AB - Background: Parkinson's disease (PD) is often accompanied by clinically identified depression. Providing effective pharmacotherapies that concomitantly treat both motor and psychological symptoms can pose a challenge to physicians. For this reason, alternatives to standard anti-depressant treatments, such as repetitive transcranial magnetic stimulation (rTMS), have been evaluated within the Parkinson's population. Methods: A literature search was conducted on the PubMed database for all studies that evaluated rTMS as a treatment in patients with both depression and PD. A meta-analysis was performed on all studies that reported mean pre- and post-rTMS depression inventory scores. Widely used depression inventories included both self-report and clinician-administered measures. Effect size for individual study groups and across all studies was calculated. Results: Six of 7 studies meeting inclusion criteria reported significantly improved depression scores, large effect sizes, and significant p values. Total weighted average effect size was calculated at 1.32 across all study groups that applied rTMS. Conclusions: Across all but one study, rTMS appears to effectively reduce depression scores among self-reported and clinician administered inventories. The total weight average effect size showed that, when considering study sample sizes and degree of findings, this form of neurostimulation can relieve PD patients of their depressive symptoms. Further, rTMS is a promising alternative to traditional anti-depressant therapies when treating refractory depression in patients with PD.

AB - Background: The developmental study of subtypes of disordered eating (DE) during adolescence may be relevant to understand the development of eating disorders. The purpose of the present study was to identify subgroups with different profiles of DE in a community sample of adolescent girls aged 13-15 years, and to study the stability of these profiles and subgroups over a one-year interval in order to find patterns that may need to be addressed in further research and prevention. Methods: Cluster analysis according to the LICUR procedure was performed on five aspects of DE, and the structural and individual stability of these clusters was analysed. The clusters were compared with regard to BMI, body esteem, deliberate self-harm, and other kinds of psychological difficulties. Results: The analysis revealed six clusters (Multiple eating problems including purging, Multiple eating problems without purging, Social eating problems, Weight concerns, Fear of not being able to stop eating, and No eating problems) all of which had structurally stable profiles and five of which showed stability at the individual level. The more pronounced DE clusters (Multiple eating problems including/without purging) were consistently associated with higher levels of psychological difficulties and lower levels of body esteem. Furthermore, girls that reported purging reported engaging in self-harm to a larger extent. Conclusions: Subgroups of 13-15 year old girls show stable patterns of disordered eating that are associated with higher rates of psychological impairment and lower body esteem. The subgroup of girls who engage in purging also engage in more deliberate self-harm. PMID- 29588854 TI - Experimental study of beam distortion due to fiducial markers during salvage HIFU in the prostate. AB - Background: Prostate cancer is frequently treated using external beam radiation therapy (EBRT). Prior to therapy, the prostate is commonly implanted with a small number of permanent fiducial markers used to monitor the position of the prostate during therapy. In the case of local cancer recurrence, high-intensity focused ultrasound (HIFU) provides a non-invasive salvage treatment option. However, the impact of the fiducial markers on HIFU treatment has not been thoroughly studied to date. The objective of this study was to experimentally investigate the effect of a single EBRT fiducial marker on the efficacy of HIFU treatment delivery using a tissue-mimicking material (TMM). Methods: A TMM with the acoustic properties of the prostate was developed based on a polyacrylamide hydrogel containing bovine serum albumin. Each phantom was implanted with a cylindrical fiducial marker and then sonicated using a 3.3 MHz focused bowl HIFU transducer. Two sets of experiments were performed. In the first, a single lesion was created at different positions along either the anteroposterior or left-right axes relative to the marker. In the second, a larger ablation volume was created by raster scanning. The size and position of the ablated volume were assessed using a millimetre grid overlaid on the phantom. Results: The impact of the marker on the position and size of the HIFU lesion was significant when the transducer focus was positioned within 7 mm anteriorly, 18 mm posteriorly or within 3 mm laterally of the marker. Beyond this, the generated lesion was not affected. When the focus was anterior to the marker, the lesion increased in size due to reflections. When the focus was posterior, the lesion decreased in size or was not present due to shadowing. Conclusions: The presence of an EBRT fiducial marker may result in an undertreated region beyond the marker due to reduced energy arriving at the focus, and an overtreated region in front of the marker due to reflections. Depending on the position of the targeted regions and the distribution of the markers, both effects may be undesirable and reduce treatment efficacy. Further work is necessary to investigate whether these results indicate the necessity to reconsider patient selection and treatment planning for prostate salvage HIFU after failed EBRT. PMID- 29588855 TI - Phage treatment of an aortic graft infected with Pseudomonas aeruginosa. AB - Management of prosthetic vascular graft infections caused by Pseudomonas aeruginosa can be a significant challenge to clinicians. These infections often do not resolve with antibiotic therapy alone due to antibiotic resistance/tolerance by bacteria, poor ability of antibiotics to permeate/reduce biofilms and/or other factors. Bacteriophage OMKO1 binding to efflux pump proteins in P. aeruginosa was consistent with an evolutionary trade-off: wildtype bacteria were killed by phage whereas evolution of phage-resistance led to increased antibiotic sensitivity. However, phage clinical-use has not been demonstrated. Here, we present a case report detailing therapeutic application of phage OMKO1 to treat a chronic P. aeruginosa infection of an aortic Dacron graft with associated aorto-cutaneous fistula. Following a single application of phage OMKO1 and ceftazidime, the infection appeared to resolve with no signs of recurrence. PMID- 29588856 TI - Diagnosis of GATA2 haplo-insufficiency in a young woman prompted by pancytopenia with deficiencies of B-cell and dendritic cell development. AB - Background: GATA2 deficiency presents with a spectrum of phenotypes including increased susceptibility to viral and bacterial infections, multi-lineage cytopenias, aplastic anemia, leukemic transformation and lymphedema. Allogeneic transplantation is only curative therapy for GATA2 deficiency, but is associated with significant treatment related morbidity and mortality. Given the spectrum of clinical presentation, accurate diagnosis of GATA2 deficiency is necessary to identify patients early in their disease course when allogeneic bone marrow transplantation may be of clinical benefit. Case presentation: In this report, we present a GATA2 mutation diagnosed in 23-year-old woman presenting with pancytopenia, recurring oral blisters, fatigue and chronic pain. We describe markedly low levels of mature B-cells in the blood and bone marrow and the absence of detectable blood dendritic cells with normal serum immunoglobulin levels and normal numbers of marrow plasma cells. She was ultimately diagnosed with GATA2 haplo-insufficiency due to a GATA2 germ-line mutation and underwent a successful allogeneic bone marrow transplant from a 10/10 HLA matched unrelated donor. Conclusions: The case illustrates the diagnostic difficulties in identifying GATA2 deficiencies and the importance of family history and genetic testing. GATA2 plays an important role in B-cell and dendritic cell development, and decreased numbers of those cells is a characteristic feature that should prompt consideration of GATA2 deficiency in a patient with pancytopenia. Maturation of B-cells to long-lived plasma cells is relatively unaffected in GATA2 deficiency. Allogeneic stem cell transplantation can correct immune deficiencies and prevent leukemic transformation in patients with GATA2 deficiency. PMID- 29588857 TI - The role of maternal care in borderline personality disorder and dependent life stress. AB - Background: Borderline Personality Disorder (BPD) affects 0.9%-3.2% of adolescents, and more than 20% of inpatient adolescents. Life stress has been linked to BPD across the lifespan, and previous research in adults has linked BPD to dependent stress (i.e., stress induced by the individual). However, prior research has not examined dependent stress alongside BPD in adolescents. Additionally, the potential protective effect of maternal care has not been considered in this relation. This study tested a moderation model expecting that (1) BPD would be positively associated with dependent life stress, (2) maternal care would be negatively associated with BPD, and (3) maternal care would moderate the relation between BPD and dependent life stress. Method: The sample consisted of 184 adolescents recruited from an inpatient psychiatric facility serving a diverse population in the Southwestern United States. Dependent life stress, BPD, and maternal care were measured using the UCLA Life Stress Interview, DSM-IV Childhood Interview for BPD, and Kerns Security Scale, respectively. Results: Results supported the first two hypotheses; BPD diagnosis was significantly, positively associated with dependent life stress, and negatively associated with maternal availability and dependability. Contrary to the third hypothesis, no significant evidence that maternal care acts as a buffer in the relation between BPD and dependent life stress was found. Conclusions: Although maternal care was not found to moderate the association between BPD and dependent life stress, results supported previously found relations between BPD, dependent life stress, and maternal care, and did so within a diverse inpatient adolescent sample. PMID- 29588858 TI - Single nucleotide polymorphisms in asthma candidate genes TBXA2R, ADAM33 FCER1B and ORMDL3 in Pakistani asthmatics a case control study. AB - Background: Genetic variations in different loci and genes are important in asthma pathogenesis. There is much importance of various immunological pathways in the IgE secretion regulation. Alterations in any main part of these pathways can increase the risk of asthma development. Polymorphisms in these genetic markers can effect certain pathways which predict the asthma susceptibility. In the present study, SNPs directly or indirectly affecting the immunological process pathways are selected. Methods: This study was conducted to determine association of 16 SNPs in 10 candidate genes with asthma in Pakistani population in 333 asthmatic cases and 220 healthy controls. Genotyping was performed using the Sequenom Mass ARRAY iPLEX platform (14 SNPs) and TaqMan assay (2 SNPs). Results: The minor allele at two of the SNPs showed association with protection from asthma, rs1131882 in TBXA2R gene (OR 0.73, 95% CI 0.52-1.01, P = 0.05) and rs2280091 in the ADAM33 gene (OR 0.69, 95% CI 0.50-0.97, P = 0.03). For FCER1B gene, rs2583476 the asthmatic male gender had higher TT genotype counts as compared to controls (OR = 1.86, 95% CI = 1.09-3.17, p = 0.01). In rs11650680 of ORMDL3 gene the CT genotype is more prevalent in female asthma cases in comparison with female controls (OR = 1.99, 95% CI = 1.02-3.89, p = 0.03). Conclusions: This data suggests that variations at TBXA2R and ADAM33 genes are found to be associated with asthma susceptibility in Pakistan. FCER1B gene is associated with male and ORMDL3 in female asthmatics. These genetic markers can be important source of asthma risk in Pakistani population. PMID- 29588859 TI - Factors associated with the growing-finishing performances of swine herds: an exploratory study on serological and herd level indicators. AB - Background: Growing and finishing performances of pigs strongly influence farm efficiency and profitability. The performances of the pigs rely on the herd health status and also on several non-infectious factors. Many recommendations for the improvement of the technical performances of a herd are based on the results of studies assessing the effect of one or a limited number of infections or environmental factors. Few studies investigated jointly the influence of both type of factors on swine herd performances. This work aimed at identifying infectious and non-infectious factors associated with the growing and finishing performances of 41 French swine herds. Results: Two groups of herds were identified using a clustering analysis: a cluster of 24 herds with the highest technical performance values (mean average daily gain = 781.1 g/day +/- 26.3; mean feed conversion ratio = 2.5 kg/kg +/- 0.1; mean mortality rate = 4.1% +/- 0.9; and mean carcass slaughter weight = 121.2 kg +/- 5.2) and a cluster of 17 herds with the lowest performance values (mean average daily gain =715.8 g/day +/ 26.5; mean feed conversion ratio = 2.6 kg/kg +/- 0.1; mean mortality rate = 6.8% +/- 2.0; and mean carcass slaughter weight = 117.7 kg +/- 3.6). Multiple correspondence analysis was used to identify factors associated with the level of technical performance. Infection with the porcine reproductive and respiratory syndrome virus and the porcine circovirus type 2 were infectious factors associated with the cluster having the lowest performance values. This cluster also featured farrow-to-finish type herds, a short interval between successive batches of pigs (<=3 weeks) and mixing of pigs from different batches in the growing or/and finishing steps. Inconsistency between nursery and fattening building management was another factor associated with the low-performance cluster. The odds of a herd showing low growing-finishing performance was significantly increased when infected by PRRS virus in the growing-finishing steps (OR = 8.8, 95% confidence interval [95% CI]: 1.8-41.7) and belonging to a farrow-to-finish type herd (OR = 5.1, 95% CI = 1.1-23.8). Conclusions: Herd management and viral infections significantly influenced the performance levels of the swine herds included in this study. PMID- 29588860 TI - Technology-based functional assessment in early childhood intervention: a pilot study. AB - Background: Electronic patient-reported outcomes (e-PROs) may provide valid and feasible options for obtaining family input on their child's functioning for care planning and outcome monitoring, but they have not been adopted into early intervention (EI). The purpose of this pilot study was to evaluate the feasibility of implementing technology-based functional assessment into EI practice and to examine child, family, service, and environmental correlates of caregiver-reported child functioning in the home. Methods: In a cross-sectional design, eight individual EI providers participated in a 90-min technology-based functional assessment training to recruit participants and a 60-min semi structured focus group post data collection. Participants completed the Young Children's Participation and Environment Measure (YC-PEM) home section online and Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT) via iPad. Participants' EI service use data were obtained from administrative records. Results: A total of 37 caregivers of children between 6 and 35 months old (mean age = 19.4, SD = 7.7) enrolled, a rate of 44% (37/84) in 2.5 months. Providers suggested expanding staff training, gathering data during scheduled evaluations, and providing caregivers and providers with access to assessment summaries. Caregivers wanted their child's participation to change in 56% of home activities. Lower caregiver education and higher EI intensity were related to less child involvement in home activities. Conclusions: Implementing technology based functional assessment is feasible with modifications, and these data can be useful for highlighting child, family, and EI service correlates of caregiver reported child functioning that merit further study. Feasibility results informed protocol modifications related to EI provider training, timing of data collection, and management of EI service use data extraction, as preparation for a subsequent scale-up study that is underway. PMID- 29588861 TI - Standing Practice In Rehabilitation Early after Stroke (SPIRES): a functional standing frame programme (prolonged standing and repeated sit to stand) to improve function and quality of life and reduce neuromuscular impairment in people with severe sub-acute stroke-a protocol for a feasibility randomised controlled trial. AB - Background: The most common physical deficit caused by a stroke is muscle weakness which limits a person's mobility. Mobility encompasses activities necessary for daily functioning: getting in and out bed, on/off toilet, sitting, standing and walking. These activities are significantly affected in people with severe stroke who typically spend most of their time in bed or a chair and are immobile. Immobility is primarily caused by neurological damage but exacerbated by secondary changes in musculoskeletal and cardiorespiratory systems. These secondary changes can theoretically be prevented or minimised by early mobilisation, in this case standing up early post-stroke.Standing up early post stroke has been identified as an important priority for people who have suffered a severe stroke. However, trials of prolonged passive standing have not demonstrated any functional improvements. Conversely, task-specific training such as repeated sit-to-stand has demonstrated positive functional benefits. This feasibility trial combines prolonged standing and task-specific strength training with the aim of determining whether this novel combination of physiotherapy interventions is feasible for people with severe stroke as well as the overall feasibility of delivering the trial. Methods/design: This is a pragmatic multi centre parallel single-blinded two-armed feasibility randomised controlled trial. Fifty people with a diagnosis of severe stroke will be randomly allocated to either the functional standing frame programme or usual physiotherapy. All patient participants will be assessed at baseline and followed up at 3 weeks, then 3, 6 and 12 months post-randomisation. Trial objectives are to determine the feasibility according to the following indicators:: (i) Process: recruitment and retention rate, ability to consent, eligibility criteria, willingness/ability of physiotherapists to recruit, willingness of patients to be randomised, and acceptability of the intervention; (ii) Resource: burden and potential costs; (iii) Management: treatment fidelity, participant adherence, acceptability and completeness of outcome measures, impact and management or orthostatic hypotension; and (iv) Safety: number and nature of adverse and serious adverse events. Discussion: The functional standing frame programme addresses a key concern for people who have suffered a severe stroke. However, several uncertainties exist which need to be understood prior to progressing to a full scale trial, including acceptability and tolerance of the functional standing frame programme intervention and practicality of the trial procedures. This feasibility trial will provide important insights to resolve these uncertainties. Trial registration: International Standard Randomised Controlled Trial Number ISRCTN15412695.

PMID- 29588862 TI - Invasive urodynamic testing prior to surgical treatment for stress urinary incontinence in women: cost-effectiveness and value of information analyses in the context of a mixed methods feasibility study. AB - Background: INVESTIGATE-I (INVasive Evaluation before Surgical Treatment of Incontinence Gives Added Therapeutic Effect?) was a mixed methods study to assess the feasibility of a future randomised controlled trial of invasive urodynamic testing (IUT) prior to surgery for stress urinary incontinence (SUI) in women. Here we report one of the study's five components, with the specific objectives of (i) exploring the cost-effectiveness of IUT compared with clinical assessment plus non-invasive tests (henceforth described as 'IUT' and 'no IUT' respectively) in women with SUI or stress-predominant mixed urinary incontinence (MUI) prior to surgery, and (ii) determining the expected net gain (ENG) from additional research. Methods: Study participants were women with SUI or stress-predominant MUI who had failed to respond to conservative treatments recruited from seven UK urogynaecology and female urology units. They were randomised to receive either 'IUT' or 'no IUT' before undergoing further treatment. Data from 218 women were used in the economic analysis. Cost utility, net benefit and value of information (VoI) analyses were performed within a randomised controlled pilot trial. Costs and quality-adjusted life years (QALYs) were estimated over 6 months to determine the incremental cost per QALY of 'IUT' compared to 'no IUT'. Net monetary benefit informed the VoI analysis. The VoI estimated the ENG and optimal sample size for a future definitive trial. Results: At 6 months, the mean difference in total average cost was L138 (p = 0.071) in favour of 'IUT'; there was no difference in QALYs estimated from the SF-12 (difference 0.004; p = 0.425) and EQ-5D-3L (difference - 0.004; p = 0.725); therefore, the probability of IUT being cost effective remains uncertain. The estimated ENG was positive for further research to address this uncertainty with an optimal sample size of 404 women. Conclusions: This is the largest economic evaluation of IUT. On average, up to 6 months after treatment, 'IUT' may be cost-saving compared to 'no IUT' because of the reduction in surgery following invasive investigation. However, uncertainty remains over the probability of 'IUT' being considered cost-effective, especially in the longer term. The VoI analysis indicated that further research would be of value.

AB - Introduction: Little is known about the antimicrobial susceptibility of common bacteria responsible for wound infections from many countries in sub-Saharan Africa. Methods: We performed a retrospective review of microbial isolates collected based on clinical suspicion of wound infection between 2004 and 2016 from Mercy Ships, a non-governmental organisation operating a single mobile surgical unit in Benin, Congo, Liberia, Madagascar, Sierra Leone and Togo. Antimicrobial resistant organisms of interest were defined as methicillin resistant Staphylococcus aureus (MRSA) or Enterobacteriaceae resistant to third generation cephalosporins. Generalised mixed-effects models accounting for repeated isolates in a patient, potential clustering by case mix for each field service, age, gender and country were used to test the hypothesis that rates of antimicrobial resistance differed between countries. Results: 3145 isolates from repeated field services in six countries were reviewed. In univariate analyses, the highest proportion of MRSA was found in Benin (34.6%) and Congo (31.9%), while the lowest proportion was found in Togo (14.3%) and Madagascar (14.5%); country remained a significant predictor in multivariate analyses (P=0.002). In univariate analyses, the highest proportion of third-generation cephalosporin resistant Enterobacteriaceae was found in Benin (35.8%) and lowest in Togo (14.3%) and Madagascar (16.3%). Country remained a significant predictor for antimicrobial-resistant isolates in multivariate analyses (P=0.009). Conclusion: A significant proportion of isolates from wound cultures were resistant to first line antimicrobials in each country. Though antimicrobial resistance isolates were not verified in a reference laboratory and these data may not be representative of all regions of the countries studied, differences in the proportion of antimicrobial-resistant isolates and resistance profiles between countries suggest site-specific surveillance should be a priority and local antimicrobial resistance profiles should be used to guide empiric antibiotic selection.

AB - Idelalisib is a first-in-class oral selective inhibitor of phosphatidylinositol 3 kinase delta, which is selectively expressed in hematopoietic cells, where it is critical to B-cell receptor signaling and B-cell development and function. Idelalisib is approved in the United States for the treatment of relapsed chronic lymphocytic leukemia (CLL; in combination with rituximab), relapsed follicular lymphoma (FL), and small lymphocytic lymphoma (SLL) and in the European Union for the treatment of CLL (in combination with rituximab). Approval was based on clinical activity in a phase II trial in indolent non-Hodgkin lymphoma and a phase III trial in CLL. Because idelalisib is a relatively new treatment option for patients with relapsed CLL, SLL, and FL, with a safety profile distinct from other agents, it is important for advanced practitioners (APs) to familiarize themselves with the adverse event (AE) profile and educate their patients as well. As active members of the oncology care team, APs can play a vital role in optimizing outcomes in patients receiving idelalisib therapy. This review will familiarize APs with the AE profile of idelalisib and provide practical information about the identification and management of AEs associated with idelalisib therapy. PMID- 29588867 TI - Clinical Management of Bowel Dysfunction After Low Anterior Resection for Rectal Cancer. AB - The American Cancer Society estimated that 39,610 new cases of rectal cancer were diagnosed in the United States in 2015. Surgery is the primary treatment for rectal cancer, with the majority of patients undergoing sphincter-preserving surgery with low anterior resection. Although low anterior resection can prevent patients from having a permanent colostomy, bowel dysfunction may occur in 60% to 90% of patients. Bowel dysfunction symptoms may include fecal and gas incontinence, urgency, frequent bowel movements, clustering of stools, and difficulty emptying. The symptoms collectively are referred to as low anterior resection syndrome (LARS) and adversely affect quality of life. There are no specific therapies for management of LARS. This comprehensive literature review evaluates evidence-based, clinical nonsurgical interventions for symptom management of LARS and will assist advanced practitioners in recognizing symptoms and implementing clinical interventions in the outpatient setting for management of LARS.

PMID- 29588869 TI - A Descriptive, Longitudinal Study of Quality of Life and Perceived Health Needs in Patients With Head and Neck Cancer. AB - Patients with head and neck cancer have numerous concerns and symptoms in the first year of posttreatment survivorship and are especially vulnerable at the end of treatment and 1 month posttreatment. This article shares the findings of a descriptive, longitudinal study of health-related quality of life (HRQOL) in patients with head and neck cancer from the beginning of treatment through 12 months posttreatment. The primary objective of this study was to describe the symptom experience and health needs of patients receiving radiation for head and neck cancer to support the establishment of an advanced practitioner (AP) clinic for head and neck cancer survivors. Significant findings in this study showed HRQOL at the end of treatment was significantly lower than baseline (p < .001). Low scores persisted through 1 month, with gradual recovery by 12 months. Fatigue and anxiety had the highest mean scores, yet anxiety improved with time, whereas fatigue did not. Positive human papillomavirus status was statistically associated with higher anxiety. Socioeconomic status negatively impacted HRQOL. Themes of perceived health needs were managing oral symptoms, returning to a normal life, and regaining energy. The AP in oncology can play a pivotal role in providing comprehensive assessment, symptom management, health education, and supportive counseling in this population throughout treatment and survivorship.

PMID- 29588873 TI - Community's Emergency Preparedness for Flood Hazards in Dire-dawa Town, Ethiopia: A Qualitative Study. AB - Background: Emergency preparedness at all levels (individuals and communities) is the corner stone of effective response to the increasing trends of global disasters due to man-made and natural hazards. It is determined by different factors, including (among others) past direct and indirect exposures to hazards. This study was carried out in Dire Dawa town, Ethiopia, which in the past experienced frequent flooding events, yet dearth of information exists about preparedness in the area. The aim of the study was to assess the levels of emergency preparedness for flood hazards at households and communities levels. Methods: The study was conducted in a qualitative approach and was conducted in Dire Dawa town, which has been divided into nine administrative-units called Kebeles. Two focus group discussions were held in two of these units (Kebele-05 and 06), each focus group comprising twelve people (all above 18 years of age), and in total 24 people (13 females and 11 males) took part in the study. Open ended questions were used that could guide the discussions, and the discussions were audio-taped and transcribed. The results were translated from local language to English and qualitatively presented. Results: The findings of focus group discussions showed that the local government in collaboration with the federal government built the flood protection dams in areas where flood hazards have been thought to be repeatedly wreaking havoc, specifically after the flood disaster of the year 2006. In addition, in Kebele-05, where one Non-Governmental Organization (NGO) was operating on flood hazards prevention and mitigation program, some non structural emergency preparedness measures were undertaken by the communities. These non-structural measures (the major ones) entailed: establishment of committees recruited from residents and training them to raise awareness among communities on emergency preparedness; some residents made changes to their own houses (retrofitted) and put sandbags around their houses to temporarily protect the flooding; establishment of communication channels between communities to alarm each other in the event of flood disaster; and reforestation of the already deforested mountainous areas surrounding the town. However, concerns were raised by study participants about strengths of the constructed flood protection dams. Furthermore, the non-structural emergency preparedness measures identified by this study were not comprehensive; for example, residents were not trained in first aid, first aid kits were not provided, there was no linkage being established between communities and health facilities so as to provide emergency medical care to victims in the event of flood disaster. Discussion: The findings of this study concur with some of the previous quantitative studies' results in that the past direct and indirect disaster experiences invoke preparedness intention and actual preparedness for flood hazards at individuals, communities and organizations levels. The only one quantitative and behavioral based study conducted thus far in Dire Dawa town reported the strong association of past flood disaster experience with household emergency preparedness. Among the residents there was a tendency to rely on the dams to be constructed with "good quality" and "higher strength" than making preparedness efforts on their own at their households. Structural measures such as building of dams, dikes, levees, and channel improvements could be means of mitigation measures; however, solely relying on these measures could have far reaching consequences. Conclusions: To mitigate flood hazards, dams were built and in addition, in Kebele-05 where an NGO was operating, some non-structural emergency preparedness measures were undertaken. In the course of construction of flood protection dams, ensuring communities' involvement is needed; and at the same time undertaking comprehensive non-structural emergency preparedness measures in all Kebeles is highly recommended.

AB - The rising prevalence of food allergy and specifically peanut allergy has had significant implications for affected patients, families, and society. The current standard of care remains strict avoidance and the use of emergency medications for accidental ingestions. There is recent evidence-based information to suggest that one approach to preventing peanut allergy lies in early introduction of peanut. This represents a paradigm shift from previous recommendations and has led to updated guidelines in the United States, Europe, and Australasia on the introduction of potentially allergenic foods in the infant diet. This new approach to prevention has some practical obstacles and challenges associated with its implementation. There is also growing interest in the role of maintaining a healthy skin barrier in prevention of sensitization and food allergy. Other approaches, including pro- and prebiotics, prenatal maternal dietary avoidance, breastfeeding, and the use of specific formulas, have not shown reproducibly favorable results. As children with peanut allergy are unlikely to outgrow their food allergy, early oral immunotherapy in those with established peanut allergy is being investigated with the hopes of altering the natural history of an otherwise lifelong disease. PMID- 29588874 TI - Clinical and Laboratory Profile of Zika and Dengue Infected Patients: Lessons Learned From the Co-circulation of Dengue, Zika and Chikungunya in Brazil. AB - BACKGROUND: The current triple epidemic caused by dengue, zika and chikungunya constitutes a serious health problem in Brazil. The aim of this study was to investigate acute samples (up to the 7 days of symptoms) from patients presenting acute fever syndrome suspected as arboviral infection and characterize the clinical and laboratorial profile during the co-circulation of dengue, zika and chikungunya in Campo Grande, Mato Grosso do Sul (MS), midwest region of Brazil. METHODS: All suspected cases (n=134) were tested by using serological and molecular diagnostic tests including DENV, ZIKV and CHIKV RT-PCR, Dengue nonstructural protein 1 (NS1) antigen capture ELISA, anti- DENV IgM ELISA and anti-CHIKV IgM ELISA. In addition, clinical, hematological and biochemical parameters of infected patients were analyzed. RESULTS: It was observed that 79.1% of the blood samples were confirmed for ZIKV and/or DENV infection Of those, 38.0% patients were DENV monoinfected, 26.8% were ZIKV monoinfected and 13.4% were DENV/ZIKV co-infected. Seven patients presented Chikungunya IgM antibodies indicating a previous CHIKV infection. Common symptoms included fever, rash, arthralgia, myalgia, prostration, headache and conjunctivitis. Statistical analysis showed that pruritus and edema were associated with ZIKV infection while prostration and vomiting were more associated with dengue. Additionally, total protein and ALT levels were significantly different in DENV patients compared to ZIKV ones. Some DENV infected patients as well as co-infected needed hospitalization and venous hydration. Otherwise, most ZIKV infected patients presented mild clinical course. Among the pregnant women studied (n=11), three were ZIKV monoinfected while four were DENV monoinfected and two were DENV-1/ZIKV coinfected. In general, normal birth outcomes were observed except for the death due to respiratory insufficiency of one baby born to a mother coinfected with DENV-1/ZIKV. CONCLUSIONS: Herein, we provide evidence of the co-circulation of DENV, ZIKV and CHIKV infections in the Campo Grande, MS, Brazil, with a high frequency of DENV-1/ZIKV coinfection. Laboratorial diagnosis poses a challenge where those arboviruses are endemic and differential diagnosis proved to imperative for cases characterization. The knowledge about disease severity during arbovirus coinfections is still scarce and there are several issues emphasizing the importance of adequate management of patients at risk areas. PMID- 29588875 TI - Incidence Prediction for the 2017-2018 Influenza Season in the United States with an Evolution-informed Model. AB - Introduction: Seasonal influenza is responsible for a high disease burden in the United States and worldwide. Predicting outbreak size in advance can contribute to the timely control of seasonal influenza by informing health care and vaccination planning. Methods: Recently, a process-based model was developed for forecasting incidence dynamics ahead of the season, with the approach validated by several statistical criteria, including an accurate real-time prediction for the past 2016-2017 influenza season before it started. Results: Based on this model and data up to June 2017, a forecast for the upcoming 2017-2018 influenza season is presented here, indicating an above-average, moderately severe, outbreak dominated by the H3N2 subtype. Discussion: The prediction is consistent with surveillance data so far, which already indicate the predominance of H3N2. The forecast for the upcoming 2017-2018 influenza season reinforces the importance of the on-going vaccination campaign. PMID- 29588876 TI - Ectopic Telomerase Expression Fails to Maintain Chondrogenic Capacity in Three Dimensional Cultures of Clinically Relevant Cell Types. AB - The poor healing capacity of cartilage and lack of effective treatment for associated disease and trauma makes it a strong candidate for a regenerative medicine approach. Potential therapies tested to date, although effective, have met with a number of intrinsic difficulties possibly related to limited autologous chondrocyte cell yield and quality of cartilage produced. A potential mechanism to bypass limited cell yields and improve quality of differentiation is to immortalize relevant cell types through the ectopic expression of telomerase. Pellet cultures of human chondrocytes (OK3), bone marrow mesenchymal stem cells (BMA13), and embryonic stem cell (H1 line)-derived cells (1C6) and their human telomerase reverse transcriptase (hTERT) transduced counterparts were maintained for 20 days in standard maintenance medium (MM) or transforming growth factor beta3-supplemented prochondrogenic medium (PChM). Pellets were assessed for volume and density by microcomputed tomography. Quantitative gene expression (COL1A2, COL2A1, COL3A1, COL6A3, COL10A1, ACAN, COMP, SOX9); sulfated glycosaminoglycans (sGAGs), and DNA quantification were performed. Histology and immunohistochemistry were used to determine matrix constituent distribution. Pellet culture in PChM resulted in significantly larger pellets with an overall increased density when compared with MM culture. Gene expression analysis revealed similarities in expression patterns between telomerase-transduced and parental cells in both MM and PChM. Of the three parental cell types examined OK3 and BMA13 produced similar amounts of pellet-associated sGAG in PChM (4.62 +/- 1.20 and 4.91 +/- 1.37 MUg, respectively) with lower amounts in 1C6 (2.89 +/- 0.52 MUg), corresponding to 3.1, 2.3, and 1.6-fold increases from day 0. In comparison, telomerase-transduced cells all had much lower sGAG with OK3H at 2.74 +/- 0.11 MUg, BMA13H 1.29 +/- 0.34 MUg, and 1C6H 0.52 +/- 0.01 MUg corresponding to 1.2, 0.87, and 0.34-fold changes compared with day 0. Histology of day 20 pellets displayed reduced staining overall for collagens and sGAG in telomerase transduced cells, most notably with alterations in aggrecan and collagen VI; all cells stained positively for collagen II. We conclude that while telomerase transduction may be an effective technique to extend cellular proliferative capacity, it is not sufficient in isolation to sustain a naive chondrogenic phenotype across multiple cell types.

Bariatr Surg Pract Patient Care 2017;12(1):35-42. DOI: 10.1089/bari.2016.0036. PMID- 29588877 TI - Patient-Perceived Autonomy and Long-Acting Reversible Contraceptive Use: A Qualitative Assessment in a Midwestern, University Community. AB - Long-acting reversible contraceptives (LARCs) are the most effective contraceptives and are first-line recommendations for most women. However, young women use these methods at relatively low rates. Given concern with contraceptive coercion, an underexamined factor contributing to LARC attitudes is women's perceived reproductive and bodily autonomy in regard to LARC. We conducted focus group discussions and interviews regarding LARC perceptions and knowledge with 50 women between the ages of 18 and 29. We used a modified grounded theory approach to analyze young women's impressions of autonomy in relation to contraceptives more generally and LARC more specifically, both among ever-users and never-users. Four themes emerged regarding women's perceived autonomy with LARC. Control over pregnancy, active participation versus external agent, control over bleeding patterns, and autonomy in the provider/patient relationship. Within most themes, women made both positive and negative associations between perceived autonomy and LARC. The provider/patient relationship was a modifier of other themes, in that cooperative relationships may overshadow other perceived reductions in autonomy, and more unbalanced relationships may heighten perceived reductions in autonomy. Ever-users were more likely to report increased autonomy with LARC use, whereas never-users were more likely to express concerns about loss of autonomy with LARC. This study suggests that perceived autonomy may influence women's perceptions of LARC as well as their uptake of these contraceptive methods, with several factors both positively and negatively related to women's perceived autonomy. We encourage the integration of these findings into patient-centered counseling as well as educational materials for LARC. PMID- 29588879 TI - Suprasellar Tumors (Part 2). PMID- 29588880 TI - Endoscopic Endonasal Approach to a Suprasellar Craniopharyngioma. AB - We present the case of a 57-year-old male who presented with progressive right side vision loss whose workup revealed a large suprasellar lesion with invasion of the third ventricle. The pituitary stalk was not visible. Hormonal panel showed no hormonal deficits. The initial diagnosis was of a type II transinfundibular craniopharyngioma (as classified by Kassam et al). An endoscopic endonasal transplanum transtuberculum approach was done using a standard binostril four-hand technique, with the patient positioned supine with the head turned to the right side and tilted to the left, fixed in a three-pin head clamp, under imaging guidance. The tumor was carefully dissected away from the optic apparatus while preserving the vessels, mainly the superior hypophyseal artery. The stalk was identified around the tumor and preserved. The third ventricle was entered and inspected at the end of the procedure and a near-total resection (a small residual in the right hypothalamus) with decompression of the optic apparatus was achieved. Reconstruction was done in a multilayered fashion, using collagen matrix and a nasoseptal flap. Patient had an uneventful postoperative stay and was discharged on POD 4, neurologically stable with no hormonal deficits. Pathology confirmed an adamantinomatous craniopharyngioma. Due to a small growth of the residual, patient underwent fractionated stereotactic radiation (50.4Gy in 28 sessions). He presented with panhypopituitarism 2 years after radiation therapy. At 3-month follow-up, his vision was back to normal and 6-year postoperative magnetic resonance imaging showed no signs of recurrence.

PMID- 29588881 TI - Orbitopterional Approach for the Resection of a Suprasellar Craniopharyngioma: Adapting the Strategy to the Microsurgical and Pathologic Anatomy. AB - Objectives To describe the orbitopterional approach for the resection of a suprasellar craniopharyngioma with emphasis on the microsurgical and pathological anatomy of such lesions. Design After completing the orbitopterional craniotomy in one piece including a supraorbital ridge osteotomy, the Sylvian fissure was split in a distal to proximal direction. The ipsilateral optic nerve and internal carotid artery were identified. Establishing a corridor to the tumor through both the opticocarotid and optic cisterns allowed for a wide angle of attack. Using both corridors, a microsurgical gross total resection was achieved. A radical resection required transection of the stalk at the level of the hypothalamus. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Understanding the cisternal and topographic relationships of the optic nerve, optic chiasm, and internal carotid artery is critical to achieving gross total resection while preserving normal anatomy. Participants The surgery was performed by the senior author assisted by Dr. Jaafar Basma. The video was edited by Dr. Vincent Nguyen. Outcome Measures Outcome was assessed with extent of resection and postoperative visual function. Results A gross total resection of the tumor was achieved. The patient had resolution of her bitemporal hemianopsia. She had diabetes insipidus with normal anterior pituitary function. Conclusions Understanding the microsurgical anatomy of the suprasellar region and the pathological anatomy of craniopharyngiomas is necessary to achieve a good resection of these tumors. The orbitopterional approach provides the appropriate access for such endeavor. The link to the video can be found at: https://youtu.be/Be6dtYIGqfs . PMID- 29588882 TI - Endoscopic Endonasal Approach for a Suprasellar Craniopharyngioma. AB - Objectives The current video presents the nuances of an endoscopic endonasal approach to a suprasellar craniopharyngioma. Design The video analyzes the presentation, preoperative workup and imaging, surgical steps and technical nuances of the surgery, the clinical outcome, and follow-up imaging. Setting The patient was treated by a skull base team consisting of a neurosurgeon and an ENT surgeon, at a teaching academic institution. Participants The case refers to a 67-year-old man who presented with vision loss and headaches, and was found to have a suprasellar mass, with imaging characteristics consistent with a craniopharyngioma. Main Outcome Measures The main outcome measures consistent of the reversal of the patient symptoms (vision loss and headaches), the recurrence free survival based on imaging, as well as the absence of any complications. Results The patient's vision improved after the surgery; at his last follow-up there was no evidence of recurrence on imaging. Conclusions The endoscopic endonasal approach is safe and effective in treating suprasellar craniopharyngiomas. The link to the video can be found at: https://youtu.be/p1VXbwnAWCo . PMID- 29588883 TI - Resection of a Retrochiasmatic Craniopharyngioma by Combined Modified Orbital Craniotomy and Transnasal Endoscopic Techniques. AB - A 20-year-old patient presented with hydrocephalus but intact vision and hormone function. The MRI showed a large seller, suprasellar and third ventricular mass. We chose a combined approach utilizing the translyvian, lamina terminals route, with a possible interhemispheric approach. But, we also utilized a transnasal endoscopic approach for the tumor that remained below the diaphragma sellae. The patient did well, with complete tumor resection via a staged approach, but did require hormone replacement. The link to the video can be found at: https://youtu.be/yzpfOxzI4cQ . PMID- 29588884 TI - Endoscopic Endonasal Approach for Resection of a Pediatric Craniopharyngioma: Operative Video and Technical Nuances. AB - We present a pediatric case of a retrochiasmatic craniopharyngioma in the suprasellar region with third ventricular extension that was resected through a purely endoscopic endonasal approach (EEA) via the transplanum transtuberculum corridor. The patient is a 12-year-old boy who presented with progressive visual loss and panhypopituitarism. The EEA allows direct visualization of the undersurface of the optic chiasm and hypothalamus so that safe and meticulous tumor dissection can be performed to preserve these critical neurovascular structures. This video atlas demonstrates the operative technique and surgical nuances of the endoscopic skull base approach, microdissection of the tumor from the critical neurovascular structures, and multilayered reconstruction of the skull base defect with a nasoseptal flap. A gross total resection was achieved, and the patient was neurologically intact with improved visual acuity and visual fields. In summary, the EEA via the transplanum transtuberculum corridor is an important strategy in the armamentarium for surgical management of pediatric craniopharyngiomas.

AB - Objectives Complete surgical resection is an important prognostic factor for recurrence and is the best management for craniopharyngioma. This operative video demonstrates the technical nuances in achieving complete resection of a suprasellar craniopharyngioma. Design and Setting The surgery was performed in a middle-aged lady who presented with the history of progressive bitemporal hemianopia and excessive sleepiness over 8 months. On imaging, suprasellar craniopharyngioma was identified. The tumor was approached through opticocarotid cistern and lamina terminalis. Exposure of bilateral optic nerves, right internal carotid artery, anterior cerebral artery, and its perforator branches was then afforded and the tumor was gross totally resected. Results The author demonstrates step-by-step technique of microsurgical resection of suprasellar craniopharyngioma. The narrow corridor to deeper structures, intricacies of multiple perforator vessels, and the technique of arachnoid and capsule dissection are the main challenging factors for the gross total resection of craniopharyngioma. The tumor portion which lies under the ipsilateral optic nerve is a blind spot region with a high chance of leaving residual tumor. Mobilization of optic nerve may endanger visual function too. The use of handheld mirror ['mirror-technique'] helps in better visualization of this blind spot and achieve complete excision. Conclusions The technical pearls of craniopharyngioma surgery include the optimum utilization of translamina terminalis route, wide opening of the cisterns, meticulous separation of deep perforator vessels, capsular mobilization/traction avoidance, and the use of "mirror-technique" for blind-spot visualization. These surgical strategies help to achieve complete resection without causing neurological deficit. The link to the video can be found at: https://youtu.be/9wHJ4AUpG50 . PMID- 29588886 TI - Endoscopic Endonasal Transplanum Transtuberculum Approach for the Resection of a Large Suprasellar Craniopharyngioma. AB - Objectives To demonstrate an endoscopic endonasal transplanum transtuberculum approach for the resection of a large suprasellar craniopharyngioma. Design Single-case-based operative video. Setting Tertiary center with dedicated skull base team. Participants A 72-year-old male patient diagnosed with a suprasellar craniopharyngioma. Main Outcomes Measured Surgical resection of the tumor and preservation of the normal surrounding neurovascular structures. Results A 72 year-old male patient presented with a 1-year history of progressive bitemporal visual loss. He also referred symptoms suggestive of hypogonadism. Neurological examination was unremarkable and endocrine workup demonstrated mildly elevated prolactin levels. Magnetic resonance images demonstrated a large solid-cystic suprasellar lesion, consistent with the diagnosis of craniopharyngioma. The lesion was retrochiasmatic, compressed the optic chiasm, and extended into the interpeduncular cistern ( Fig. 1 ). Because of that, the patient underwent an endoscopic endonasal transplanum transtuberculum approach. 1 2 3 The nasal stage consisted of a transnasal transseptal approach, with complete preservation of the patient's left nasal cavity. 4 The cystic component of the tumor was decompressed and its solid part was resected. It was possible to preserve the surrounding normal neurovascular structures ( Fig. 2 ). Skull base reconstruction was performed with a dural substitute, a fascia lata graft, and a right nasoseptal flap ( Video 1 ). The patient did well after surgery and referred complete visual improvement. However, he also presented pan-hypopituitarism on long-term follow up. Conclusions The endoscopic endonasal route is a good alternative for the resection of suprasellar lesions. It permits tumor resection and preservation of the surrounding neurovascular structures while avoiding external incisions and brain retraction.

AB - We present a 37-year-old male case of cystic suprasellar huge craniopharyngioma, who presented with significant memory disturbance due to obstructive hydrocephalus. Combined interhemispheric and pterional approach was chosen to resect huge suprasellar tumor. Interhemispheric trans-lamina terminalis approach was quite effective to resect third ventricular tumor, while pterional approach was useful to dissect tumor out of basilar perforators and stalk.

PMID- 29588888 TI - Extended Endoscopic Endonasal Resection of a Suprasellar and Third Ventricular Retrochiasmatic Craniopharyngioma with a Narrow Pituitary Gland-Optic Chiasm Interval: Techniques to Optimize Resection. AB - The extended endoscopic endonasal approach can be utilized to surgically treat pathology within the suprasellar space. This relies on a sufficient corridor and interval between the superior aspect of the pituitary gland and the optic chiasm. Tumors located in the retrochiasmatic space and within the third ventricle, however, may not have a widened interval through which to work. With mass effect on the superior and posterior aspect of the optic chiasm, the corridor between the chiasm and the pituitary gland might even be further narrowed. This may negate the possibility of utilizing the endoscopic endonasal approach for the management of pathology in this location. We present a case of a retrochiasmatic craniopharyngioma with a narrow resection corridor that was treated with the extended endoscopic approach and we review techniques to potentially overcome this limitation.

AB - The orbitopterional approach provides an excellent combination of basal access and suprasellar access. This approach also allows for less brain retraction when resecting larger suprasellar tumors that are more superiorly projecting due to a more frontal and inferior trajectory. In this operative video, the authors thoroughly detail an orbitopterional craniotomy utilizing a one-piece modified orbitozygomatic technique. This technique involves opening the craniotomy through a standard pterional incision. The craniotomy is performed using the standard three burr holes of a pterional approach; however, the osteotomy is extended anteriorly through the frontal process of the zygomatic bone as well as through the supraorbital rim. In this operative video atlas, the authors illustrate the operative anatomy, as well as surgical strategy and techniques to resect a large suprasellar craniopharyngioma in a 4-year-old male. Other reasonable approach options for a lesion of this size would include a standard pterional approach, a supraorbital approach, or expanded endoscopic transsphenoidal approach. The lesion was quite high and thus, the supraorbital approach may confine access to the superior portion of the tumor. While recognizing that some groups may have chosen the endoscopic expanded transsphenoidal approach for this lesion, the authors describe more confidence in achieving the goal of a safe and maximal resection with the orbitopterional approach.

PMID- 29588890 TI - Endoscopic Transsphenoidal Salvage Surgery for Symptomatic Residual Cystic Craniopharyngioma after Radiotherapy. AB - Objectives Ideal treatment of craniopharyngiomas is still controversial. Radiotherapy (RT) is considered effective for recurrences or after subtotal tumor removal (STR). About 40 to 50% of patients may experience tumor cyst expansion soon after RT; in these cases, the role of salvage surgery is debated. Design Operative video. Setting Tertiary care center. Participants An 11-year-old boy diagnosed with persistent craniopharyngioma. In 2015, the patient underwent right frontotemporal craniotomy for STR at another center, complicated by panhypopituitarism. Two years later, fractionated 54-Gy RT was performed on growing residual tumor. After 3 months, he was admitted to our hospital due to persistent malaise, vomiting, pulsating headache, and epistaxis. Ophthalmologic evaluation evidenced left homonymous hemianopsia. Results A contrast-enhanced magnetic resonance imaging (MRI) showed a 27-mm cystic component enlarging from the cranial end of the persistent craniopharyngioma lesion, extending into the third ventricle. Biventricular hydrocephalus and brain midline shift to the right were present. Compared with the early post-RT MRI, the cystic component of the tumor demonstrated growth. The patient underwent external ventricular drainage placement for emergent treatment of hydrocephalus and endoscopic transsphenoidal surgery. After cystic content drainage, the lesion was completely removed with its capsule. A "gasket seal" technique was performed for skull base reconstruction, with autologous fascia lata, septal bone, and mucoperiosteum from inferior turbinate. Histologic examination confirmed the craniopharyngioma diagnosis. Postoperative MRI showed resolution of the hydrocephalus and complete tumor removal. Conclusion Although shrinkage of cystic components of craniopharyngioma residuals may occur within 5 to 6 months after RT, salvage surgery is indicated in symptomatic patients.

AB - Objective To demonstrate the transchoroidal approach for the resection of a recurrent craniopharyngioma. Design Video case report. Setting Microsurgical resection. Participant The patient was a 27-year-old woman with a history of a craniopharyngioma, resected twice during the year prior to presentation to our unit. Both operations were done via the left anterolateral corridor, and afterward, she was blind in the left eye and was treated with Desmopressin (DDAVP) for diabetes insipidus (DI). Serial magnetic resonance imaging (MRI) showed progression of the tumor residual, and she was referred for further surgical intervention. Main Outcome Measures Pre- and postoperative MRIs measured the degree of resection. Results For this, her third surgery, a transcallosal, transchoroidal approach, was chosen to offer the widest possible exposure. Given her history, an aggressive total resection was the best strategy. The patient was placed supine with the head neutral. A right frontal craniotomy allowed access to the interhemispheric fissure. By opening the corpus callosum, the left lateral ventricle was entered. The transchoroidal approach started with dissection of the tenia fornicis to open the choroidal fissure. After this, sufficient exposure to the posterior parts of the tumor was gained. Resection proceeded to the bottom of the tumor, exposing the basilar apex and interpeduncular cistern, and continued back anteriorly. In the end, a microscopic total resection was achieved. With a long hospital stay to treat her brittle DI, the patient slowly returned to neurological baseline. Conclusion The transchoroidal approach is an effective way to remove large tumors in the third ventricle. The link to the video can be found at: https://youtu.be/2-Aqjaay8dg . PMID- 29588892 TI - Orbitopterional Approach with Extradural Clinoidectomy for the Resection of a Tuberculum Sellae Meningioma: Adapting the Strategy to the Microsurgical and Pathological Anatomy. AB - Objectives To describe the orbitopterional approach with extradural clinoidectomy for the resection of a tuberculum sellae meningioma, with an emphasis on the microsurgical and pathological anatomy of such lesions. Design After completing the orbitopterional craniotomy in one piece, the optic nerve is identified extradurally, unroofed, and the clinoid process resected. The falciform ligament is divided and the optic nerve is decompressed extradurally. Opening the frontotemporal dura exposes the tumor in the subfrontal region. The tumor is followed along the ipsilateral and contralateral optic nerves, and its dural tail is cut and coagulated at the level of the tuberculum. Care is taken to preserve the optic nerve perforators during the dissection. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Participants The surgery was performed by the senior author assisted by Dr. Jaafar Basma, neurosurgery fourth-year resident. The video was edited by Dr. Vincent Nguyen, neurosurgery third-year resident. Outcome Measures Outcome was assessed with the extent of resection and visual symptoms. Results A near-total resection of the tumor was achieved. A small part of tumor significantly adherent to the optic nerve was intentionally left behind. The patient had a stable vision examination postoperatively. Conclusions Understanding the microsurgical anatomy of the suprasellar region and the pathological anatomy of the tuberculum sellae meningioma is necessary to achieve a good resection of these tumors while preserving functionality of the optic apparatus. The orbitopterional approach with anterior clinoidectomy provides the appropriate access for such endeavor. The link to the video can be found at: https://youtu.be/WtAP8uqSW0M . PMID- 29588893 TI - Lateral Supraorbital Craniotomy for Tuberculum Sella Meningioma Resection. AB - Tuberculum sella meningioma can be approached by either open or endoscopic approaches. The aim of this video case presentation is to highlight the nuances of the lateral supraorbital craniotomy for tuberculum sella meningioma resection. The authors present a 34-year-old female patient who presented with decreased right eye visual acuity (20/60), afferent pupillary defect, and nasal field cut due to a tuberculum sella meningioma. The tumor was partially encasing the left A1 artery, severely displacing the optic apparatus, and minimally invading the right optic canal. The lateral supraorbital craniotomy was considered the most suitable approach to this tumor. The operative nuances and pitfalls of this approach are detailed in the video. Gross total resection of the tumor was achieved and confirmed with postoperative MRI. The patient's vision gradually improved and she was discharged on the fourth postoperative day. The minimally invasive lateral supraorbital craniotomy for tuberculum sella meningioma is a suitable approach in selected cases. The link to the video can be found at: https://youtu.be/yG8q6YH2D9k . PMID- 29588894 TI - Surgery of Tuberculum Sellae Meningioma: A Technical Purview on Pterional Approach. AB - Objective Amidst the raging debate between transnasal and transcranial approaches, the critical factor that dictates success lies in the meticulous dissection of the tumor from the optic apparatus, anterior communicating artery complex, and the pituitary stalk. In this surgical video, we describe the resection of a tuberculum sellae meningioma through the pterional approach highlighting dissection through the appropriate arachnoidal plane. Case Description The patient is a 75-year-old female who presented with optic nerve compression with bitemporal hemianopia and endocrine function abnormalities. A transcranial approach was done to effectively decompress the optic nerve. The video includes a detailed discussion on the surgical techniques including working between the different surgical corridors, working in the arachnoid plane to dissect the neurovascular structures away from the tumor, identification, and preservation of pituitary stalk. Postoperatively, the patient's visual field deficit improved with a remaining isolated right temporal field defect at 2 months follow-up. Her endocrine function improved after the surgery. Conclusion In the era of endoscopic surgery, transcranial approaches for suprasellar tumors like tuberculum sellae meningiomas still have a distinct surgical role. Our discussion extends to reiterate the strengths and weaknesses of the transcranial approach to this region as compared with the endoscopic approach. We believe decompression of optic nerves, separation of Acom complex from the tumor, and preservation of pituitary stalk are better achieved through a transcranial approach.

AB - A 61-year-old male patient presented with recurrent malignant meningioma involving the left optic canal and decreased vision from the left eye. The patient had undergone orbital exenteration on the right 2 years ago. The decision to treat the patient was made based on the significant vision deterioration and rapid tumor growth. Endoscopic transsphenoidal approach considered the most suitable route due to the inferomedial invasion of the optic canal. Gross total removal was achieved and the patient's vision improved postoperatively. The patient developed hydrocephalus 4 weeks postoperatively and cerebrospinal fluid (CSF) leak. Ventriculoperitoneal shunt placement corrected both hydrocephalus and CSF leak. The link to the video can be found at: https://youtu.be/2cOF0pf5gAk .

AB - We present the case of a 67-year-old female with an incidental finding of a left sided tuberculum sellae meningioma on a brain magnetic resonance imaging (MRI) for an unrelated complaint. Formal visual field testing showed a small defect in the inferior nasal and temporal fields of the left eye, compatible with mass effect on the optic nerve by the tumor. An endoscopic endonasal transtuberculum approach with decompression of the left optic nerve was performed using a standard binostril four-hand technique, with the patient positioned supine with the head turned to the right side and tilted to the left, fixed in a three-pin head clamp, under imaging guidance. After exposure, we drilled the tuberculum sellae and the floor of the sella and after opening the dura, the tumor and optic nerve came into view. The tumor was completely removed and we confirmed the patency of all perforating vessels using indocyanine green. Reconstruction was done in a multilayered fashion, using collagen matrix and a nasoseptal flap. Patient had an uneventful postoperative stay and was discharged on postoperative day 3, neurologically stable with no new hormonal deficits. Pathology report confirmed a WHO Grade I meningioma with Ki -67 of 1% and 3-month postoperative MRI confirmed a gross total resection and visual fields exam showed a complete recovery.

PMID- 29588897 TI - Endoscopic Endonasal Transplanum-Transtuberculum Sellae Approach for the Resection of a Diaphragma Sellae Meningioma. AB - The endoscopic endonasal approach (EEA) provides a direct access to diaphragma sellae meningiomas. We present a case of a 56-year-old-female with an incidentally diagnosed sellar/suprasellar lesion with no hormonal deficit; thus, she opted for conservative management initially. During her annual follow-up appointment with her ophthalmologist, it was noticed that the patient had right eye peripheral deficit on formal visual field testing. Magnetic resonance imaging (MRI) revealed an enlargement of the sellar/suprasellar mass, causing displacement of the optic chiasm. A transplanum-transtuberculum EEA was performed. Gross-total removal was achieved and closure was done in a multilayer fashion using a collagen matrix, nasoseptal flap. Histopathological examination confirmed a meningioma WHO grade I. There were no intra- or postoperative complications. At 4-year-follow-up, the patient has stable vision and MRI brain showed no recurrence.

AB - Introduction A variety of dural openings are described for frontal-temporal and cranio-orbital craniotomies. As with any surgical technique, the goal is to optimally and safely address the pathology, minimize normal anatomy disruption, and optimize postoperative recovery. This study reports a modified dural opening for frontal-temporal approaches which minimizes brain exposure while facilitating visualization for neoplastic and vascular lesions of the anterior clinoid, supra- and parasellar and adjacent regions. Methods A sample case is presented for which a low subfrontal dural exposure was utilized for tumor resection. The clinical presentation, surgical procedure, and outcome are summarized including a video detailing the surgical technique. Results A 63-year-old female with gradual left eye vision loss and tumor enlargement on serial imaging. The small dural-based tumor arose from the left anterior clinoid and optic canal region compressing the optic nerve. The video shows a left frontal-temporal craniotomy used to perform extradural anterior clinoidectomy and optic canal decompression. The novel low subfrontal dural opening without fixed brain retraction allowed dural opening around the optic canal and clinoidectomy region to resect tumor and complete optic nerve decompression. Postoperatively, the patient did well with significant recovery of vision and follow-up at 2.5 years shows no evidence of tumor recurrence. Conclusion The novel low subfrontal dural opening provides access to lesions of the supra-and para-sellar and adjacent regions, and preservation of much of the dura avoids some of the risks of intradural dissection including Sylvian fissure dissection and brain retraction The link to the video can be found at: https://youtu.be/Jc7wvR4PTFk . PMID- 29588899 TI - Combined Frontotemporal Transbasal Approach for the Resection of a Giant Rathke's Cleft Cyst: Operative Video and Technical Nuances. AB - We present a case of a giant Rathke's cleft cyst with significant superior extension into the third and right lateral ventricles and lateral extension into the left Sylvian fissure and over the anterior clinoid process. An extended modification of the frontotemporal approach was performed using a combined frontotemporal transbasal approach. This allowed wide exposure to both transsylvian and subfrontal corridors to the retrochiasmatic space. This video atlas demonstrates the operative technique and surgical nuances of the skull base approach, microdissection of the tumor, and safe handling of the neurovascular structures. A gross total resection was achieved and the patient was neurologically intact with improved visual acuity. In summary, the combined frontotemporal transbasal approach is an important strategy in the armamentarium for the surgical management of giant Rathke's cleft cysts.

AB - Objectives The current video presents the nuances of an interhemispheric, translamina terminalis approach for the resection of suprasellar cavernous malformation. Design The video analyzes the presentation, preoperative workup and imaging, surgical steps and technical nuances of the surgery, the clinical outcome, and follow-up imaging. Setting The patient was treated by a skull base team at a teaching academic institution. Participants The case refers to a 64 year-old female who presented with vision loss and confusion, and was found to have a suprasellar mass, with imaging characteristics consistent with a cavernous malformation of the third ventricle. Main Outcome Measures The main outcome measures consist of the reversal of the patient symptoms (vision loss and confusion), the recurrence-free survival based on imaging, as well as the absence of any complications. Results The patient's mental status improved slightly after surgery. There was no evidence of recurrence. Conclusions The interhemispheric, translamina terminalis approach is safe and effective for the resection of suprasellar cavernous malformations.

PMID- 29588901 TI - Endoscopic Endonasal Transtuberculum Sellae Approach for the Resection of Suprasellar Intrainfundibular Epidermoid Cyst. AB - A 49-year-old female presented with intense headaches of 3 months duration. Brain magnetic resonance imaging (MRI) was performed and showed a sellar-suprasellar lesion extending into the third ventricle. A presumptive diagnosis of a craniopharyngioma was made. Since the patient did not have any visual deficits, she opted for conservative management. Four months later, she started to have progressive deterioration of vision; thus, surgery was indicated. The patient underwent endoscopic endonasal resection of the lesion through a transtuberculum sellae approach. The patient was positioned supine with the head slightly extended and the face turned to the right side. Following the essence of a binostril four-hand technique, a total gross resection of the lesion was achieved and multilayer skull base reconstruction was performed utilizing collagen matrix and nasoseptal flap; with no intraoperative complications. The patient's postoperative course was uneventful with the improvement in her vision, and she was discharged on postoperative day 4 with no new neurological deficits. Histopathological examination confirmed the diagnosis of an epidermoid cyst. Postoperative pituitary gland function was within normal limits except for mild diabetes insipidus for which she is on DDAVP 0.1 mg twice daily. At 4 years follow-up, the patient was doing well, her vision was normalized, and brain MRI revealed no evidence of residual or recurrent lesion.

PMID- 29588902 TI - Gross Total Resection of Chordoid Glioma of the Third Ventricle via Anterior Interhemispheric Transcallosal Transforaminal Approach at Two Stages. AB - Suprasellar tumors in particular tumors located in the retrochiasmatic area and anterior third ventricle are challenging cases in terms of optimal surgical exposure. Several approaches have been described including transsylvian, translamina terminalis, endoscopic endonasal, and anterior interhemispheric. Each approach has advantages and disadvantages. In this video, we present a case of retrochiasmatic anterior third ventricular tumor that was operated via anterior interhemispheric transcallosal transforaminal approach. The patient is a 42-year old female who presented with sudden onset of severe headache and depressed level of consciousness. Computed tomography (CT) scan of the head showed a hemorrhage in the third ventricle and suprasellar cisterns. CT angiogram and magnetic resonance imaging (MRI) confirmed diagnosis of hemorrhagic mass lesion in the third ventricle. Upon further questioning of her family, we found out that she was having excessive urination and short-term memory problems for last 2 weeks. First, ventriculostomy was placed for obstructive hydrocephalus. She then underwent surgical resection via anterior interhemispheric transcallosal transforaminal approach. Foramen of Monro was enlarged by performing transchoroidal dissection. Using transforaminal route, tumor was resected. Due to the narrow surgical corridor and high vascularity of the tumor, decision was made to come back at a second stage. Using same surgical approach, in the second stage, gross total resection was performed. Postoperative MRI confirmed gross total resection. Histopathology was chordoid glioma of the third ventricle. She made excellent recovery with persistent diabetes insipidus. Currently, she is completing radiation therapy. In this video, we demonstrate techniques and pitfalls of anterior interhemispheric transcallosal approach to anterior third ventricular tumor.

AB - Objectives The current video presents the nuances of the endoscopic endonasal transoculomotor triangle approach for the resection of a pituitary adenoma with extension into the ambient cistern. Design The video analyzes the presentation, preoperative workup and imaging, surgical steps and technical nuances of the surgery, the clinical outcome, and follow-up imaging. Setting The patient was treated by a skull base team consisting of a neurosurgeon and an ENT surgeon at a teaching academic institution. Participants The case refers to a 62-year-old female who presented with vision loss and headaches, and was found to have a pituitary adenoma with extension into the ambient cistern. Main Outcome Measures The main outcome measures consist of the reversal of the patient symptoms (headaches), the recurrence-free survival based on imaging, as well as the absence of any complications. Results The patient's headaches improved. There was no evidence of recurrence. Conclusions The endoscopic endonasal transoculomotor triangle approach is safe and effective for addressing pituitary tumors which extend into the ambient cistern.

AB - In this video, we describe the technical nuances of an endoscopic endonasal approach (EEA) for a complex macroadenoma with suprasellar and retrochiasmatic extension. The patient is a 51-year-old male with several years' history of progressive visual loss. Neuro-ophthalmology assessment revealed a profound visual loss with homonymous hemianopsia and left optic nerve atrophy. His pituitary hormonal profile was normal. The options for surgical approach included transcranial, endoscopic endonasal, or a combination of both. An EEA was the preferred surgical option, because it allows for early identification of the pituitary gland, and provides access to the suprasellar region including pre- and retrochiasmatic spaces, which facilitates tumor removal while minimizing manipulation of the optic apparatus. While most pituitary adenomas do not require extracapsular subarachnoidal dissection, there are complex adenomas with subarachnoidal invasion and multilobulated morphology, such as the one presented here, that require a combination of internal debulking, extracapsular and subarachnoidal dissection. The technique presented here allows for complete tumor resection, avoiding the risk of postoperative apoplexy of residual adenoma, and facilitates identification of perforating branches and neural structures that require meticulous preservation. Here, we also illustrate the proper management of reconstruction-related complications. Postoperative course was complicated with meningitis with necrotic nasoseptal flap and required surgical debridement, new inferior turbinate flap, fascia lata, lumbar drain, and 6-week antibiotic treatment. Imaging follow-up showed complete removal of tumor. The patient had significant improvement in visual fields and left visual acuity, and no postoperative hormonal dysfunction.

PMID- 29588905 TI - Endoscopic Endonasal Resection of a Suprasellar Pituitary Adenoma Mimicking Tuberculum Sellae Meningioma in a Patient with an Intrasellar Persistent Trigeminal Artery. AB - A 50-year-old female with an incidentally diagnosed suprasellar lesion was initially managed conservatively due to the presence of an intrasellar persistent trigeminal artery going through the dorsum sellae and fundamentally forming the blood supply of the entire posterior circulation. Serial follow-up brain magnetic resonance imaging (MRI) revealed progressive enlargement of the suprasellar lesion over 4 years period. Surgery was indicated after the initial tumor growth; however, the patient refused surgery for fear of complications related to the persistent trigeminal artery. Two-and-a-half years later, she presented with deterioration of vision. Formal visual field testing revealed a right temporal field defect. Brain MRI demonstrated significantly enlarged suprasellar lesion, most consistent with tuberculum sellae meningioma, exerting mass effect on the optic apparatus. The patient underwent endoscopic endonasal resection of the lesion through a transplanum/transtuberculum approach. Intraoperatively, absence of hypertrophic McConnel arteries, hyperostosis, and the fact that the dura was soft and not under tension was against the diagnosis of tuberculum sellae meningioma. Additionally, the tumor consistency was similar to a pituitary adenoma. A complete resection was accomplished and multilayer skull base reconstruction was performed with no complications. On postoperative day 1 (POD 1), she was operated upon for the evacuation of small suprasellar hematoma associated with vision deterioration. Histopathological examination confirmed the diagnosis of atypical pituitary adenoma with Ki -67 labeling index of 4 to 5%. The patient ultimately recovered well with improved vision, and was discharged on POD 4 with no new neurological deficits. At 4 years follow-up, her vision was normalized and brain MRI showed no residual or recurrent lesion. The link to the video can be found at: https://youtu.be/QZmzctjAEbw . PMID- 29588906 TI - Complications of Extended Endoscopic Endonasal Surgery in Elderly Patients. AB - Extended endoscopic endonasal procedures are not unique among surgical interventions in carrying increased risk in the elderly population. There are, however, components of the procedure, namely high-flow cerebrospinal fluid leaks, that do result in the potential for increased perioperative morbidity for these patients. We present the case of a 77-year-old male with a large invasive pituitary macroadenoma resected through a transplanum-transtuberculum-transsellar endonasal approach. A gross total resection was obtained with resolution of the patient's preoperative ophthalmologic deficits. One month postoperatively, the patient developed progressive lethargy and cranial imaging demonstrated a left convexity subacute subdural hematoma. This was evacuated through a twist drill craniostomy. Despite measures to limit the operative time of the initial endonasal procedure as well as the absence of a postoperative cerebrospinal fluid fistula, the patient still developed this complication. Along with more typical potential causes of postoperative decline following extended endonasal procedures, problems from high-flow intraoperative cerebrospinal fluid leaks alone can result in morbidity in the elderly population. This should be acknowledged preoperatively and a high suspicion should exist for the presence of intracranial hemorrhage in these patients with any postoperative deficits. Additional intraoperative measures can be utilized to minimize such risks. The link to the video can be found at: https://youtu.be/EkLmt2T8_UE .

AB - Extracerebral toxoplasmosis, with pulmonary involvement and shock, is a rare form of toxoplasmosis in patients with advanced AIDS. It can mimic pneumocystosis, histoplasmosis, and disseminated tuberculosis, and should be considered in the differential diagnosis of causes of respiratory failure and fulminant disease in this group of individuals, especially in areas where the Toxoplasma gondii infection is highly prevalent and in those without proper use of antimicrobial prophylaxis. We report the case of a 46-year-old male patient who presented to the emergency department with uremia, requiring urgent dialysis. During the laboratorial investigation, the patient had confirmed HIV infection, with a low CD4+ peripheral T-cell count (74 cells/uL). During hospitalization, the patient presented drug-induced hepatitis due to trimethoprim/sulfamethoxazole in a prophylactic dose, requiring interruption of this medication. On the 55th day of hospitalization, the patient developed refractory shock and died. At the autopsy, disseminated toxoplasmosis with encephalitis and severe necrotizing pneumonia were diagnosed, with numerous tachyzoites in the areas of pulmonary necrosis.

AB - Background: The objective of this study was to evaluate the influence of masticatory muscle injection of botulinum toxin type A (BTX-A) on the growth of the mandibular bone in vivo. Methods: Eleven Sprague-Dawley rats were used, and BTX-A (n = 6) or saline (n = 5) was injected at 13 days of age. All injections were given to the right masseter muscle, and the BTX-A dose was 0.5 units. All of the rats were euthanized at 60 days of age. The skulls of the rats were separated and fixed with 10% formalin for micro-computed tomography (micro-CT) analysis. Results: The anthropometric analysis found that the ramus heights and bigonial widths of the BTX-A-injected group were significantly smaller than those of the saline-injected group (P < 0.05), and the mandibular plane angle of the BTX-A injected group was significantly greater than in the saline-injected group (P < 0.001). In the BTX-A-injected group, the ramus heights II and III and the mandibular plane angles I and II showed significant differences between the injected and non-injected sides (P < 0.05). The BTX-A-injected side of the mandible in the masseter group showed significantly lower mandibular bone growth compared with the non-injected side. Conclusion: BTX-A injection into the masseter muscle influences mandibular bone growth. PMID- 29588911 TI - Intimate Partner Violence Among Transgender Youth: Associations with Intrapersonal and Structural Factors. AB - Intimate partner violence (IPV) is a serious public health problem, linked with a number of poor health outcomes. Some research demonstrates that transgender and gender nonconforming (TGNC) youth may experience IPV at similar rates to heterosexual cisgender women; however, there is a dearth of data examining the experiences of IPV among this population. The exclusion of TGNC youth in IPV research and public health interventions is problematic because it contributes to a traditional gender-based heterosexual model of IPV that ignores the specific needs of TGNC populations. Given the pervasiveness of transphobic stigma in the United States and the complexities of the lives of TGNC youth, it is important to understand how both structural and individual factors are associated with IPV among TGNC youth. Using data from a cross-sectional survey of 131 TGNC youth from 14 different cities in the United States representing various regions of the country, this study explores the associations between a range of structural and intrapersonal factors and experiences of IPV victimization among TGNC youth. Separate logistic regression models were fit to examine the relationships between structural and intrapersonal factors and IPV. Structural results found that TGNC youth experiencing extreme victimization, a history of incarceration, and participation in sex work were much more likely to report IPV. The only intrapersonal variable that was associated with IPV was depressive symptomatology; however, this relationship was strong, with participants being nearly eight times more likely to report IPV if they experienced symptoms of depression. Gaining a better understanding of the complexity of both structural and intrapersonal factors among TGNC youth will greatly inform the development of IPV prevention and services for TGNC youth experiencing this type of violence. PMID- 29588914 TI - Association of ACL Laxity Tests with Arthroscopic Findings in Chronic ACL and PCL Deficient Knees. AB - An anterior cruciate ligament (ACL) injury may be diagnosed by clinical examination and radiological investigation using magnetic resonance imaging or by arthroscopy. 1,2 Based on our experience, the ACL tear in concomitant chronic ACL and posterior cruciate ligament (PCL) deficient knees may produce knee laxity, which is more difficult to assess on clinical examination, which in turn may affect the management algorithm of the patient. Our hypothesis is that, in a concomitant chronic ACL and PCL injury, posterior capsular contracture and abnormal reattachment of torn ACL will result in less clinical and subjective laxity, preoperatively. The aim of this study is to review a cohort of patients who had undergone PCL reconstructive surgery and compare the preoperative clinical assessments with and without anesthesia with arthroscopic finding of ACL. This is to assess the accuracy and reliability of clinical ACL laxity tests in detecting ACL tear in chronic ACL and PCL injury. PMID- 29588912 TI - Changes Over Time in Nasopharyngeal Colonization in Children Under 2 Years of Age at the Time of Diagnosis of Acute Otitis Media (1999-2014). AB - Background: In children with acute otitis media (AOM), a decrease in nasopharyngeal (NP) colonization with vaccine serotypes of Streptococcus pneumoniae has been noted since the introduction of pneumococcal conjugate vaccines (PCVs). The purpose of this study is to describe corresponding changes in colonization with Haemophilus influenzae. Methods: In 4 separate studies, we obtained NP cultures from children aged 6-23 months presenting with AOM. Cohort 1 was recruited before routine use of PCV7 (1999-2000); 93% of children in cohort 2 (2003-2005) and 100% in cohort 3 (2006-2009) received >=2 doses of PCV7. All children in cohort 4 (2012-2014) received >=2 doses of PCV13. Isolates of H. influenzae were tested for beta-lactamase production; beta-lactamase negative isolates from cohorts 3 and 4 underwent susceptibility testing. Results: A total of 899 children were evaluated. NP colonization with H. influenzae was found in 26% of children in cohort 1 (n = 175), 41% in cohort 2 (n = 87), 33% in cohort 3 (n = 282), and 29% in cohort 4 (n = 355). Colonization with H. influenzae increased initially from cohort 1 to cohort 2 (P = .01), then decreased across cohorts 2, 3, and 4 (P = .03, test for trend). The prevalence rates of beta lactamase production were 27%, 42%, 33%, and 30% in each of the 4 cohorts, respectively (P = .50). Conclusions: Although an initial increase in H. influenzae colonization was observed, suggesting an impact of PCVs, the most recent prevalence rates of NP colonization with H. influenzae and beta-lactamase production were like those observed before universal administration of PCV7. This knowledge is critical to guide appropriate treatment recommendations for children with AOM. PMID- 29588913 TI - Dynamics of Colonization of Streptococcus pneumoniae Strains in Healthy Peruvian Children. AB - Background: Although asymptomatic carriage of Streptococcus pneumoniae (Spn) is common, acquisition of the bacteria is the first step in disease pathogenesis. We examined the effect of introduction of the 7-valent pneumococcal vaccine on Spn carriage patterns in a cohort of Peruvian children. Methods: We used data from a prospective cohort study that collected monthly nasopharyngeal samples from children under 3 years of age. Spn isolates were serotyped using Quellung reactions, and bacterial density was determined by quantitative polymerase chain reaction. Changes in Spn carriage patterns, including the rate of carriage and number and density of serotypes carried over time, were evaluated before (2009) and after widespread vaccination with PCV7 (2011). Using all pneumococcal detections from each child and year, we identified serotypes that were present both at first and last detection as "persisters" and serotypes that replaced a different earlier type and were detected last as "recolonizers." Results: Ninety two percent (467/506) of children in 2009 and 89% (451/509) in 2011 carried Spn at least once. In 2009 and 2011, rates of carriage were 9.03 and 9.04 Spn detections per person-year, respectively. In 2009, 23F, a serotype included in PCV7, was the only type identified as a persister and 6A, 15B, and 19A were identified as recolonizer serotypes. In 2011, 6B and 7C were persister serotypes and 13 was a frequent recolonizer serotype. Conclusions: Overall Spn carriage among children under 3 in Peru was similar before and after introduction of PCV7; however, serotype-specific rates and longitudinal carriage patterns have shifted.

PMID- 29588915 TI - Recurrent 8-Year Ongoing Unilateral Breast Seroma Formation after PIP Implant Removal-A Case Report and Review of the Literature. AB - Late seroma formation is a rare complication after implant-based breast enlargement surgery and even less frequent after implant removal. This case report presents a case of painful recurrent seroma formation after the removal of a ruptured Poly Implants Prothese implant. A 52-year-old patient presented herself in our clinic with a clinical history of recurrent unilateral seroma of the right breast over a period of 8 years after the initial unilateral implant removal. Removal of the remaining implant and complete bilateral capsulectomy was performed. Intraoperative findings revealed a macroscopically thickened capsule with signs of chronic inflammation on the affected side. The clinical history and the macroscopic appearance of the capsule demanded histopathological exclusion of a possible anaplastic large cell lymphoma. Histopathological and microbiological analysis of the capsule and encapsulated material revealed no signs of malignancy or infection. Immediate soft tissue reconstruction of the breast was successfully performed using autologous fat transfer. An aesthetically satisfying result regarding symmetry and volume was achieved, and no further seroma formation was observed within a 6-month follow-up period. Level of evidence: V, Case Report. PMID- 29588917 TI - A National Needs Assessment of Canadian Nurse Practitioners Regarding Cannabis for Therapeutic Purposes. AB - Introduction: In Canada, the Access to Cannabis for Medical Purposes Regulations (ACMPR) has given nurse practitioners (NPs) the power to authorize cannabis for therapeutic purposes (CTP) to eligible patients. This expansion in NPs' scope of practice underscores the importance of delivering balanced, evidence-based education on cannabis to NPs. The aim of this national study was to assess NPs' knowledge and practice gaps related to CTP to inform the development of future education resources that increase NPs' clinical competence and improve patient care related to medical cannabis. Methods: This is a quantitative, descriptive exploratory design study. A national online survey of NPs was conducted from August 2013 to June 2014. NPs were recruited through email lists held by numerous Canadian nursing organizations. The survey was adapted from a previous national survey that assessed CTP educational needs among Canadian physicians. The survey assessed NPs' knowledge, experience, barriers, and attitudes related to CTP as well as preferred format for future CTP education. Results: The sample consisted of 182 NPs from across Canada. The largest knowledge gap was related to dosing and creating effective treatment plans for patients using CTP. The majority of respondents (76.3%) ranked the need for education on CTP to be either strong or very strong. Over half (57%) reported that they would be comfortable authorizing medical cannabis through the ACMPR; this number increased to 64% if they were to receive appropriate education. Conclusion: Nursing regulatory organizations, in partnership with academic institutions and government agencies, must work toward the development of educational and clinical competencies specific to CTP. Tailored education programs are needed to address the knowledge gaps held by NPs and the clinical barriers they face to including CTP as part of their care. PMID- 29588918 TI - Percutaneous and Endoscopic Management of Nephrolithiasis in a Patient with Five Native Ureters (Trifid Right and Bifid Left Collecting System). AB - Triplication of the ureter is a rare urologic finding that has been well described in the literature. Patients can present with urinary tract infections, incontinence, and calculi. We present the case of a patient with extensive stone burden with right trifid and left bifid collecting systems. Stone management was performed with a multimodal approach using a combination of endoscopic and percutaneous approaches. Our systematic and staged approach highlights a method for efficacious stone treatment in a complex endourologic case. PMID- 29588919 TI - Laparoscopic Surgery for Seminal Vesicle Cysts and Ureterocele with Urination Disorder: A Case Report of Zinner Syndrome. AB - Background: Zinner syndrome is defined as seminal vesicle cysts with ipsilateral renal agenesis and an ectopic ureter. Symptomatic cases are very rare. In this article, we present a laparoscopic approach for a case of Zinner syndrome. Case Presentation: The patient was a 21-year-old male with difficult urination. A right seminal vesicle cyst and right kidney agenesis associated with ureterocele were found on examination and he was diagnosed with Zinner syndrome. First, we performed transperineal puncture of the ureterocele because it closed the bladder neck during voiding. Although voiding symptoms temporarily improved, the ureterocele recurred soon and the urination disorder was reexacerbated. Next, we selected laparoscopic removal of the ureterocele and the seminal vesicle cyst. The procedure was performed with transperitoneal access using four trocars. Perioperative and postoperative complications were not observed, and micturition was satisfactory after surgery. Conclusion: Treatment for difficult urination because of Zinner syndrome is mostly selected puncture of the ureterocele or seminal vesicle cyst. However, some patients experience recurrence. The laparoscopic approach is minimally invasive and provides a satisfactory surgical field. Therefore, it should be considered the method of treatment for symptomatic Zinner syndrome. PMID- 29588920 TI - Optimisation of ex vivo memory B cell expansion/differentiation for interrogation of rare peripheral memory B cell subset responses. AB - Background: Human memory B cells play a vital role in the long-term protection of the host from pathogenic re-challenge. In recent years the importance of a number of different memory B cell subsets that can be formed in response to vaccination or infection has started to become clear. To study memory B cell responses, cells can be cultured ex vivo, allowing for an increase in cell number and activation of these quiescent cells, providing sufficient quantities of each memory subset to enable full investigation of functionality. However, despite numerous papers being published demonstrating bulk memory B cell culture, we could find no literature on optimised conditions for the study of memory B cell subsets, such as IgM + memory B cells. Methods: Following a literature review, we carried out a large screen of memory B cell expansion conditions to identify the combination that induced the highest levels of memory B cell expansion. We subsequently used a novel Design of Experiments approach to finely tune the optimal memory B cell expansion and differentiation conditions for human memory B cell subsets. Finally, we characterised the resultant memory B cell subpopulations by IgH sequencing and flow cytometry. Results: The application of specific optimised conditions induce multiple rounds of memory B cell proliferation equally across Ig isotypes, differentiation of memory B cells to antibody secreting cells, and importantly do not alter the Ig genotype of the stimulated cells. Conclusions: Overall, our data identify a memory B cell culture system that offers a robust platform for investigating the functionality of rare memory B cell subsets to infection and/or vaccination. PMID- 29588921 TI - Characterisation of innate lymphoid cell populations at different sites in mice with defective T cell immunity. AB - Background: Innate lymphoid cells (ILCs) have now been identified within most tissues of the body and current evidence indicates that this family of cells play a fundamental role in maintaining tissue homeostasis. However, few studies have compared the ILC populations between several tissues. Methods: We sought to generate a comprehensive characterisation of the ILC populations in different tissues of C57BL/6 WT and genetically modified mice targeting costimulatory pathways, using transcription factor expression to define specific groups. Results: Consistent with studies individually describing the ILC composition in different tissues, our analysis revealed different ILC groups dominate the ILC population in different tissues. Additionally, we observed a population of IL 7Ralpha +Id2 + cells lacking expression of lineage markers but also lacking expression of GATA-3, RORgt or T-bet. This population was most evident in ear skin where it outnumbered the defined ILC groups, however, further experiments demonstrated that detection of these cells was influenced by how the tissue was digested, raising concerns as to its real nature. Since both ILC2 and ILC3 express ICOS, we then investigated the requirement for ICOS:ICOSL interactions in the homeostasis of ILC populations at these sites. Surprisingly, no significant differences were detected in the number of ILC1, ILC2 or ILC3 between WT and ICOSL -/- mice in any tissue, indicating that this pathway is not required for ILC homeostasis at these sites. These data were compared with CD80 -/-CD86 -/- mice given evidence of CD28 expression by some ILC and ILC crosstalk with activated T cells. Notably, the absence of CD28 ligands resulted in a significant increase in ILC2 and ILC3 numbers in the intestine. Conclusions: Together, these data provide new insight into ILC composition in different tissues in both WT and genetically modified mice where key costimulatory pathways are genetically deleted, providing a useful resource for further research into ILC biology. PMID- 29588922 TI - Clinical signs of trachoma are prevalent among Solomon Islanders who have no persistent markers of prior infection with Chlamydia trachomatis. AB - Background: The low population-prevalence of trachomatous trichiasis and high prevalence of trachomatous inflammation-follicular (TF) provide contradictory estimates of the magnitude of the public health threat from trachoma in the Solomon Islands. Improved characterisation of the biology of trachoma in the region may support policy makers as they decide what interventions are required. Here, age-specific profiles of anti-Pgp3 antibodies and conjunctival scarring were examined to determine whether there is evidence of ongoing transmission and pathology from ocular Chlamydia trachomatis (Ct) infection. Methods: A total of 1511 individuals aged >=1 year were enrolled from randomly selected households in 13 villages in which >10% of children aged 1-9 years had TF prior to a single round of azithromycin mass drug administration undertaken six months previously. Blood was collected to be screened for antibodies to the Ct antigen Pgp3. Tarsal conjunctival photographs were collected for analysis of scarring severity. Results: Anti-Pgp3 seropositivity was 18% in 1-9 year olds, sharply increasing around the age of sexual debut to reach 69% in those over 25 years. Anti-Pgp3 seropositivity did not increase significantly between the ages of 1-9 years and was not associated with TF (p=0.581) or scarring in children (p=0.472). Conjunctival scars were visible in 13.1% of photographs. Mild (p<0.0001) but not severe (p=0.149) scars increased in prevalence with age. Conclusions: Neither conjunctival scars nor lymphoid follicles were associated with antibodies to Ct, suggesting that they are unlikely to be a direct result of ocular Ct infection . Clinical signs of trachoma were prevalent in this population but were not indicative of the underlying rates of Ct infection. The current World Health Organization guidelines for trachoma elimination indicated that this population should receive intervention with mass distribution of antibiotics, but the data presented here suggest that this may not have been appropriate.

PMID- 29588925 TI - Not all that glitters is gold: A guide to the critical interpretation of drug trials in epilepsy. AB - Clinical trials represent the best source of evidence on which to base treatment decisions. For such evidence to be utilized meaningfully, however, it is essential that results are interpreted correctly. This requires a good understanding of strengths and weaknesses of the adopted design, the clinical relevance of the outcome measures, and the many factors that could affect such outcomes. As a general rule, uncontrolled studies tend to provide misleading evidence as a result of the impact of confounders such as regression to the mean, patient-related bias, and observer bias. On the other hand, although randomized controlled trials (RCTs) are qualitatively superior, aspects of their execution may still decrease their validity. Bias and decreased validity in RCTs may occur by chance alone (for example, treatment groups may not necessarily be balanced for important variables despite randomization) or because of specific features of the trial design. In the case of industry-driven studies, bias often influences the outcome in favor of the sponsor's product. Factors that need to be carefully scrutinized include (1) the purpose for which the trial is conducted; (2) potential bias due to unblinding or lack of blinding; (3) the appropriateness of the control group; (4) the power of the study in detecting clinically relevant differences; (5) the extent to which eligibility criteria could affect outcomes and be representative of routine clinical practice; (6) whether the treatments being compared are used optimally in terms of dosing, duration of treatment, and other variables; (7) the appropriateness of the statistical comparisons; (8) the clinical relevance of the outcome measures and whether all key outcome information is reported (for example, responder rates in completers); and (9) potential bias in the way results are presented and discussed. This article discusses each of these aspects and illustrates the discussion with examples taken from published antiepileptic drug trials.

AB - Epilepsy surgery is often the only effective treatment in appropriately selected patients with drug-resistant epilepsy, a disease affecting about 30% of those with epilepsy. We review the evidence supporting the use of epilepsy surgery, with a focus on randomized controlled trials (RCTs). Second, we identify gaps in knowledge about the benefits of epilepsy surgery for certain populations, the challenges of individualizing the choice of surgery, and our lack of understanding of the mechanisms of surgical outcomes. We conducted a search (MEDLINE, Embase, Cochrane, Clinicaltrials.gov) on March 2, 2016, to identify epilepsy surgery RCTs, systematic reviews, or health technology assessments (HTAs). Abstracts were screened to identify resective, palliative (e.g., corpus callosotomy, multiple subpial transection [MST]), ablative (e.g., Laser interstitial thermal therapy [LITT], gamma knife radiosurgery [RS]), and neuromodulation (e.g., cerebellar stimulation [CS], hippocampal stimulation [HS], repetitive transcranial magnetic stimulation [rTMS], responsive neurostimulation [RNS], thalamic stimulation [TS], trigeminal nerve stimulation [TNS], and vagal nerve stimulation [VNS]) RCTs. Study characteristics and outcomes were extracted. Knowledge gaps were identified. Of 1,205 abstracts, 20 RCTs were identified (resective surgery including corpus callosotomy [n = 7], MST [n = 0], RS [n = 1, 3 papers], LITT [n = 0], CS [n = 1], HS [n = 2], RNS [n = 1], rTMS [n = 1], TNS [n = 1], TS [n = 1], and VNS [n = 5]). Most studies targeted patients with temporal lobe epilepsy (TLE) and none examined the effectiveness of resective surgical therapies in patients with extra-TLE (ETLE) or with specific lesions aside from mesial temporal lobe sclerosis. No pediatric surgical RCTs were identified except for VNS. Few RCTs address the effectiveness of surgery in epilepsy and most are of limited generalizability. Future studies are needed to compare the effectiveness of different surgical strategies, better understand the mechanisms of surgical outcomes, and define the ideal surgical approaches, particularly for patients with high or very low cognitive function, normal imaging, or ETLE. PMID- 29588927 TI - Classification of the epilepsies: New concepts for discussion and debate-Special report of the ILAE Classification Task Force of the Commission for Classification and Terminology. AB - The ILAE Task Force on Classification presents a road map for the development of an updated, relevant classification of the epilepsies. Our objective is to explain the process to date and the plan moving forward as well as to invite further discussion about the newly proposed terms and concepts. Here, we present our response to feedback about the 2010 Organization of the Epilepsies and clarify the reintroduction of the word "classification" to map out a framework for epilepsy diagnosis. We introduce some new concepts and suggest four diagnostic levels: seizure type, epilepsy category, epilepsy syndrome, and epilepsy with (specific) etiology to denote specific levels of diagnosis. We expand the etiological categories to six, focusing on those with treatment implications. Finally, we discuss the changes in terminology originally suggested and modifications in response to comments from the epilepsy community. We welcome feedback and discussion from the global epilepsy community, particularly for the new suggested terms, so that we can cement a classification that both reflects current thinking and scientific understanding and provides a dynamic, evolving framework. PMID- 29588928 TI - The effects of carbamazepine in the intrahippocampal kainate model of temporal lobe epilepsy depend on seizure definition and mouse strain. AB - Objective: Mesial temporal lobe epilepsy (TLE) with hippocampal sclerosis is a predominant form of acquired epilepsy, characterized by recurrent simple and complex partial seizures that are often resistant to treatment. Mice developing spontaneous recurrent nonconvulsive and convulsive seizures after intrahippocampal injection of the excitotoxic glutamate agonist kainate are thought to represent a valuable model of mesial TLE. Epileptic electroencephalogram (EEG) activity recorded in this model from the kainate focus in the ipsilateral hippocampus is resistant to antiseizure drugs such as carbamazepine (CBZ). We compared the efficacy of CBZ in this model in two different mouse strains (FVB/N and NMRI). Furthermore, we evaluated whether changes in the definition of electrographic seizures affect the antiseizure efficacy of CBZ. Methods: As in previous studies, two types of epileptic EEG activity were defined: high-voltage sharp waves (HVSWs) and hippocampal paroxysmal discharges (HPDs). The characteristics of these paroxysmal EEG events in epileptic mice were compared with EEG criteria for nonconvulsive seizures in patients. For HVSWs, different spike frequencies, interevent intervals, and amplitudes were used as inclusion and exclusion criteria. In addition to CBZ, some experiments were performed with diazepam (DZP) and phenobarbital (PB). Results: Female epileptic FVB/N mice predominantly exhibited frequent HVSWs, but only infrequent HPDs or secondarily generalized convulsive seizures. Slight changes in HVSW definition determined whether they were resistant or responsive to CBZ. Male NMRI mice exhibited both HVSWs and HPDs. HVSWs were more resistant than HPDs to suppression by CBZ. Both types of epileptic EEG activity were rapidly suppressed by DZP and PB. Significance: The data demonstrate that focal electrographic seizures in the intrahippocampal kainate mouse model are less resistant than previously thought. Both mouse strain and the criteria chosen for definition of EEG seizures determine whether such seizures are drug-resistant or responsive. PMID- 29588929 TI - Long-term mortality of patients with West syndrome. AB - Objective: To study long-term survival and mortality among patients with West syndrome. Methods: The study population included all children born in 1960-1976 and treated for West syndrome in three tertiary care hospitals in Helsinki, Finland. The participants were prospectively followed for five decades for survival. Death data were derived from the National Causes of Death Register of the Population Register Center of Statistics Finland. Results: During follow-up, 102 (49%) of 207 patients had died at the mean age of 19 years. The mean overall annual mortality rate was 15.3 per 1,000 patient-years. The rates ranged from 18.2 per 1,000 after 10 years to 17.2 per 1,000 after 20 years and 15.4 per 1,000 patient-years after 40 years of follow-up. One fourth (25%) had died by 17.2 (95% CI 11.8-22.7) years and 50% by 48.6 (95% CI 38.5-NA) years of follow-up. Etiology at onset was symptomatic in 87% patients and cryptogenic in 13%; 6 of the latter 26 patients later turned out to be symptomatic. The mean annual mortality rate was 3.7 per 1,000 for 4 patients with cryptogenic etiology and 17.6 per 1,000 for those with symptomatic etiology. The hazard of death was fivefold in patients with symptomatic etiology versus cryptogenic etiology. The overall autopsy rate was 73%. Pneumonia was the most frequent cause of death (46%). All patients who died of pneumonia had symptomatic etiology. SUDEP occurred in 10 patients and was the most common epilepsy-related cause of death (10%). Significance: Risk of excess death of participants with West syndrome is not limited to early age but continues into adulthood, particularly in those with symptomatic etiology, and leads to death in half the cases at around 50 years of age. Measures should be directed to prevent pneumonia, the most common overall cause, and SUDEP, the most frequent seizure-related cause, of death.

AB - This is a commentary and an opinion paper attempting a critical reassessment of the methods and practices of epilepsy research as we see it. The enormous progress in the field of epilepsy in recent years is a cause of celebration. Advances have been made on most fronts, and the position of patients with epilepsy in society has greatly improved. However, there have also been culs-de sac and dead ends of modern science and clinical practice which are also intriguing. It may be true that we can learn more from our mistakes than from our successes. In this opinion paper, we have listed some of the successes and some of the failures of past epilepsy practice, and also areas of current practice and theory which we feel are likely to prove mistaken. The underlying reasons for misdirected practices and theories include, in our view, the influence of fashion, bad science, and the bureaucracies of practice and academic medicine. As a result, some findings are far from objective. Recognition is the first step to remediation, and hopefully future research will minimize some of the pitfalls mentioned in this article and bring the "End of Epilepsy," as defined and predicted by Oswei Temkin, closer than it is today. PMID- 29588933 TI - Behavioral disorder in people with an intellectual disability and epilepsy: A report of the Intellectual Disability Task Force of the Neuropsychiatric Commission of ILAE. AB - The management and needs of people with intellectual disability (ID) and epilepsy are well evidenced; less so, the comorbidity of behavioral disorder in this population. "Behavioral disorder" is defined as behaviors that are difficult or disruptive, including stereotypes, difficult or disruptive behavior, aggressive behavior toward other people, behaviors that lead to injury to self or others, and destruction of property. These have an important link to emotional disturbance. This report, produced by the Intellectual Disability Task Force of the Neuropsychiatric Commission of the ILAE, aims to provide a brief review of some key areas of concern regarding behavioral disorder among this population and proposes a range of research and clinical practice recommendations generated by task force members. The areas covered in this report were identified by experts in the field as being of specific relevance to the broad epilepsy community when considering behavioral disorder in persons with epilepsy and ID; they are not intended to be exhaustive. The practice recommendations are based on the authors' review of the limited research in this field combined with their experience supporting this population. These points are not graded but can be seen as expert opinion guiding future research and clinical practice. PMID- 29588934 TI - Risk of convulsive epilepsy following acute seizures in Kenyan children. AB - Objective: The prevalence of epilepsy is high in Africa, and people with epilepsy often have a history of acute seizures. We determined whether acute seizures are associated with risk for epilepsy in rural Africa, where both conditions are common and may have shared risk factors. Methods: A total of 16,438 children (2,991 with acute seizures and 13,447 without seizures) admitted to Kilifi County Hospital from 2002 to 2008 were followed up with epidemiological surveys conducted in 2003 and 2008 to assess the prevalence of epilepsy and the associated risk factors. Cox proportional hazards regression models were used to identify the risk factors. Prevalence ratios were computed using log binomial regression models. Results: The prevalence of epilepsy was higher in admissions with acute seizures (5.0% [95% confidence interval (CI), 4.3-5.9%]) than in those without seizures (0.7% [95% CI, 0.5-0.8%]), p < 0.0001). Acute seizures were associated with epilepsy after accounting for potential confounders in a Cox regression model (hazard ratio [HR] = 1.53 [95% CI, 1.10-2.14]). Prevalence was greater in complex acute seizures (5.9%; prevalence ratio [PR] = 1.58 [95% CI, 1.13-2.20]) or status epilepticus (7.5%; PR = 1.96 [95% CI, 1.32-2.91]) than in simple acute seizures (3.7%). Factors independently associated with epilepsy following acute seizures in Cox regression models were perinatal complications (HR = 3.60 [95% CI, 1.89-6.87]), cerebral palsy (HR = 1491.51 [95% CI, 144.30 15,416.21]), duration of follow-up (HR = 1.21 [95% CI, 1.09-1.35]), and malnutrition (relative risk [RR] = 0.24 [95% CI, 0.08-0.69]). Significance: Acute seizures in children are associated with subsequent risk for epilepsy that is greater than in the general population. The burden of epilepsy may be reduced by control of causes of acute seizures. PMID- 29588935 TI - A study on spike focus dependence of high-frequency activity in idiopathic focal epilepsy in childhood. AB - Objective: Spike foci in benign epilepsy with centrotemporal spikes (BECTS) are related to seizure semiologies, but this relationship is inconspicuous in Panayiotopoulos syndrome (PS). We analyzed spike-associated high-frequency activity (HFA) and its relationship to spike foci in the electroencephalograms (EEGs) of patients with BECTS and PS in order to elucidate the pathophysiology of these epileptic syndromes. Methods: In 35 patients with BECTS and 29 with PS, focal spikes in scalp sleep EEGs were first classified by clustering according to their characteristics, including shape and distribution. For each patient, three or fewer spike clusters were investigated by time-frequency spectral analysis and single-dipole analysis using a realistic three-dimensional head model to explore the relationships between the presence or absence of spike-associated HFA and the distribution of estimated spike sources. Results: A total of 159 spike clusters were analyzed (96 in BECTS and 63 in PS). HFA was detected in 73 spike clusters (76.0%) in BECTS and 37 (58.7%) in PS, with a significant difference in the proportion of spike clusters with HFA (p = 0.024 by Fisher's exact test). In BECTS, spikes had relatively uniform distributions, but the proportion of spikes with associated HFA was significantly higher in the spike group with dipoles in the perirolandic areas (42 of 49) than in that with dipoles outside of the perirolandic areas (23 of 36; p = 0.037). In PS, The proportion of spikes with associated HFA was significantly higher in the spike group with dipoles in the occipital lobes (20 of 26) than in that with dipoles outside of the occipital lobes (13 of 33; p = 0.020). Significance: The proportion of spike-associated HFA was higher in BECTS than in PS. Particular pathophysiological meaning was indicated in spikes with dipoles in the perirolandic areas in BECTS and in spikes with dipoles in the occipital lobes in PS owing to the high proportions of spike associated HFA in these areas. PMID- 29588936 TI - Cathodal transcranial direct-current stimulation for treatment of drug-resistant temporal lobe epilepsy: A pilot randomized controlled trial. AB - Objective: To investigate the effect of cathodal transcranial direct-current stimulation (c-tDCS) on seizure frequency in patients with drug-resistant temporal lobe epilepsy (TLE). Method: Twenty-nine patients with drug-resistant TLE participated in this study. They were randomized to experimental or sham group. Twenty participants (experimental group) received within-session repeated c-tDCS intervention over the affected temporal lobe, and nine (sham group) received sham tDCS. Paired-pulse transcranial magnetic stimulation was used to assess short interval intracortical inhibition (SICI) in primary motor cortex ipsilateral to the affected temporal lobe. SICI was measured from motor evoked potentials recorded from the contralateral first dorsal interosseous muscle. Adverse effects were monitored during and after each intervention in both groups. A seizure diary was given to each participant to complete for 4 weeks following the tDCS intervention. The mean response ratio was calculated from their seizure rates before and after the tDCS intervention. Results: The experimental group showed a significant increase in SICI compared to the sham group (F = 10.3, p = 0.005). None of the participants reported side effects of moderate or severe degree. The mean response ratio in seizure frequency was -42.14% (standard deviation [SD] 35.93) for the experimental group and -16.98% (SD 52.41) for the sham group. Significance: Results from this pilot study suggest that tDCS may be a safe and efficacious nonpharmacologic intervention for patients with drug resistant TLE. Further evaluation in larger double-blind randomized controlled trials is warranted. PMID- 29588937 TI - Unusual Course of Lafora Disease. AB - A 42-year-old male was admitted for refractory status epilepticus. At the age of 25, he had been diagnosed with juvenile myoclonic epilepsy. He had a stable clinical course for over a decade until a recent deterioration of behavior and epilepsy. After exclusion of acquired disorders, diagnostic work-up included application of next-generation sequencing (NGS), with a gene panel targeting progressive myoclonic epilepsies. This resulted in the diagnosis Lafora disease resulting from compound heterozygous NHLRC1 pathogenic variants. Although these pathogenic variants may be associated with a variable phenotype, including both severe and mild clinical course, the clinical presentation of our patient at this age is very unusual for Lafora disease. Our case expands the phenotype spectrum of Lafora disease resulting from pathogenic NHLRC1 variants and illustrates the value of using NGS in clinical practice to lead to a rapid diagnosis and guide therapeutic options. PMID- 29588938 TI - Partial deletion of DEPDC5 in a child with focal epilepsy. AB - We report on a child, aged 47/12 years, with borderline intelligence quotient, normal brain magnetic resonance imaging, and focal epilepsy. The polysomnographic electroencephalogram recording revealed asynchronous central spikes at both brain hemispheres resembling the features observed in focal idiopathic epileptic syndromes. Array comparative genomic hybridization analysis revealed a 32-kb partial deletion of the DEP domain-containing protein 5 (DEPDC5) gene, involved in a wide spectrum of inherited focal epileptic syndromes. The parental origin of the deletion could not be fully ascertained because the pregnancy had been achieved through anonymous egg donation and insemination by intracytoplasmic sperm injection. However, we demonstrate that the deletion, shared by all alternatively spliced isoforms of DEPDC5, produces a transcript presumably generating a DEPDC5 protein missing the entire DEP domain. Our findings suggest that partial deletion of DEPDC5 may be sufficient to cause the focal epilepsy in our patient, highlighting the importance of the DEP domain in DEPDC5 function. This study expands the phenotypic spectrum of DEPDC5 to sporadic forms of focal idiopathic epilepsy and underscores the fact that partial deletions, albeit probably very rare, are part of the genetic spectrum of DEPDC5 mutations. PMID- 29588939 TI - Cannabis in epilepsy: From clinical practice to basic research focusing on the possible role of cannabidivarin. AB - Cannabidivarin (CBDV) and cannabidiol (CBD) have recently emerged among cannabinoids for their potential antiepileptic properties, as shown in several animal models. We report the case of a patient affected by symptomatic partial epilepsy who used cannabis as self-medication after the failure of countless pharmacological/surgical treatments. Clinical and video electroencephalogram (EEG) evaluations were periodically performed, and the serum levels of CBDV, CBD, and Delta9-tetrahydrocannabinol were repeatedly measured. After cannabis administration, a dramatic clinical improvement, in terms of both decrease in seizure frequency and recovery of cognitive functions, was observed, which might parallel high CBDV plasma concentrations. To widen the spectrum of CBDV possible mechanisms of action, electrophysiological methods were applied to investigate whether it could exert some effects on gamma-aminobutyric acid (GABA)A receptors. Our experiments showed that, in human hippocampal tissues of four patients affected by drug-resistant temporal lobe epilepsy (TLE) transplanted in Xenopus oocytes, there is decrease of current rundown (i.e., reduction of use-dependent GABAA current) after prolonged exposure to CBDV. This result has been confirmed using a single case of Rasmussen encephalitis (RE). Our patient's electroclinical improvement supports the hypothesis that cannabis could actually represent an effective, well-tolerated antiepileptic drug. Moreover, the experimental data suggest that CBDV may greatly contribute to cannabis anticonvulsant effect through its possible GABAergic action. PMID- 29588941 TI - Improving clinical trial efficiency: Is technology the answer? PMID- 29588943 TI - Onchocerciasis-associated epilepsy: From recent epidemiological and clinical findings to policy implications. AB - A high prevalence of epilepsy is reported in many onchocerciasis-endemic regions. In this paper we discuss recent epidemiological and clinical aspects as well as public health implications of onchocerciasis-associated epilepsy (OAE) and propose a strategy to reduce the burden of disease. OAE probably presents in a variety of clinical manifestations, including the nodding syndrome and the Nakalanga syndrome. The most common clinical presentation, however, is generalized (primarily tonic-clonic) seizures. A characteristic of OAE is the onset of seizures between the ages of 3 and 18 years and clustering in certain families and villages close to rapid-flowing black-fly-infested rivers. A strategy combining active surveillance for epilepsy with early treatment with antiepileptic drugs and prevention of onchocerciasis by increasing the geographical and therapeutic coverage of community-directed treatment with ivermectin (CDTi) may considerably decrease the burden of disease. PMID- 29588944 TI - Defeating epilepsy: A global public health commitment. AB - This article points out that defeating epilepsy is a global public health commitment and a new challenge. This is because: epilepsy causes a heavy burden and very high treatment gap; in the field of life sciences and medicine, the 21st century would be the "Century of Brain Science"; a number of national brain research initiatives provide a great opportunity to reveal the secret of epilepsy; the Global Campaign against Epilepsy and the Mental Health Gap Action Programme made great contributions in the epilepsy control work worldwide; the historical WHA68.20 resolution gives great strength to promote defeating epilepsy. PMID- 29588942 TI - Management of post-traumatic epilepsy: An evidence review over the last 5 years and future directions. AB - Post-traumatic epilepsy (PTE) is a relatively underappreciated condition that can develop as a secondary consequence following traumatic brain injury (TBI). The aim of this rapid evidence review is to provide a synthesis of existing evidence on the effectiveness of treatment interventions for the prevention of PTE in people who have suffered a moderate/severe TBI to increase awareness and understanding among consumers. Electronic medical databases (n = 5) and gray literature published between January 2010 and April 2015 were searched for studies on the management of PTE. Twenty-two eligible studies were identified that met the inclusion criteria. No evidence was found for the effectiveness of any pharmacological treatments in the prevention or treatment of symptomatic seizures in adults with PTE. However, limited high-level evidence for the effectiveness of the antiepileptic drug levetiracetam was identified for PTE in children. Low-level evidence was identified for nonpharmacological interventions in significantly reducing seizures in patients with PTE, but only in a minority of cases, requiring further high-level studies to confirm the results. This review provides an opportunity for researchers and health service professionals to better understand the underlying pathophysiology of PTE to develop novel, more effective therapeutic targets and to improve the quality of life of people with this condition. PMID- 29588945 TI - Seven tesla MRI improves detection of focal cortical dysplasia in patients with refractory focal epilepsy. AB - Objective: The aim of this study is to determine whether the use of 7 tesla (T) MRI in clinical practice leads to higher detection rates of focal cortical dysplasias in possible candidates for epilepsy surgery. Methods: In our center patients are referred for 7 T MRI if lesional focal epilepsy is suspected, but no abnormalities are detected at one or more previous, sufficient-quality lower field MRI scans, acquired with a dedicated epilepsy protocol, or when concealed pathology is suspected in combination with MR-visible mesiotemporal sclerosis dual pathology. We assessed 40 epilepsy patients who underwent 7 T MRI for presurgical evaluation and whose scans (both 7 T and lower field) were discussed during multidisciplinary epilepsy surgery meetings that included a dedicated epilepsy neuroradiologist. We compared the conclusions of the multidisciplinary visual assessments of 7 T and lower-field MRI scans. Results: In our series of 40 patients, multidisciplinary evaluation of 7 T MRI identified additional lesions not seen on lower-field MRI in 9 patients (23%). These findings were guiding in surgical planning. So far, 6 patients underwent surgery, with histological confirmation of focal cortical dysplasia or mild malformation of cortical development. Significance: Seven T MRI improves detection of subtle focal cortical dysplasia and mild malformations of cortical development in patients with intractable epilepsy and may therefore contribute to identification of surgical candidates and complete resection of the epileptogenic lesion, and thus to postoperative seizure freedom. PMID- 29588946 TI - Effective withdrawal of antiepileptic drugs in premonitoring admission to capture seizures during limited video-EEG monitoring. AB - Objective: Withdrawal of antiepileptic drugs (AEDs) is commonly applied to capture seizures in video-EEG (vEEG) monitoring for patients with infrequent but intractable seizures. Because of the half-life of AEDs, AED withdrawal during only vEEG tends to be inadequate to provoke seizures within the vEEG admission. We hypothesize that prewithdrawal of long-half-life AEDs in premonitoring admission (PMA) is safe and effective to capture seizures in the limited time of vEEG. We determined the effect of half-life on the interval between AED withdrawal and seizure occurrence. Methods: We collected 87 patients with three criteria: (1) seizure occurrence <=3 per month; (2) AEDs >=2; (3) AED withdrawal during their admission, among 126 consecutive patients who underwent vEEG in the Department of Neurosurgery, Hiroshima University Hospital between 2011 and 2014. We divided patients into two groups on the basis of half-life of AED: Group A (23 patients) with phenobarbital (PB) and/or zonisamide (ZNS); Group B (64 patients) with other AEDs. In Group A, PB and ZNS were withdrawn during 4-day PMA before vEEG started. Further AED withdrawal was performed during vEEG, depending on the seizure occurrence. Results: The number of AEDs on admission was significantly higher in Group A (2-6, 3.5 +/- 0.9; range, mean +/-SD) than in Group B (2-5, 2.8 +/- 0.8) (p < 0.01). All 23 Group A patients and 13 (20%) Group B patients underwent AED withdrawal during PMA. Seizures occurred during PMA in two patients in both Group A (9%) and Group B (15%). The first seizure occurred significantly longer after the start of withdrawal in Group A (6.1 +/- 2.0 days) than in Group B (2.8 +/- 1.3 days) (p < 0.01). Seizures were equally captured between both groups: 96% in Group A and 92% in Group B during vEEG. Significance: For epilepsy patients who are treated with PB and/or ZNS, we recommend the planning of AED withdrawal during PMA before the start of vEEG to succeed in capturing seizures during the limited time of vEEG monitoring. PMID- 29588947 TI - The intrahippocampal kainate mouse model of mesial temporal lobe epilepsy: Lack of electrographic seizure-like events in sham controls. AB - Objective: There is an ongoing debate about definition of seizures in experimental models of acquired epilepsy and how important adequate sham controls are in this respect. For instance, several mouse and rat strains exhibit high voltage rhythmic spike or spike-wave discharges in the cortical electroencephalogram (EEG), which has to be considered when using such strains for induction of epilepsy by status epilepticus, traumatic brain injury, or other means. Mice developing spontaneous recurrent nonconvulsive and convulsive seizures after intrahippocampal injection of kainate are increasingly being used as a model of mesial temporal lobe epilepsy. We performed a prospective study in which EEG alterations occurring in this model were compared with the EEGs in appropriate sham controls, using hippocampal electrodes and video-EEG monitoring. Methods: Experiments with intrahippocampal kainate (or saline) injections started when mice were about 8 weeks of age. Continuous video-EEG recording via hippocampal electrodes was performed 6 weeks after surgery in kainate-injected mice and sham controls, that is, at an age of about 14 weeks. Three days of continuous video-EEG monitoring were compared between kainate-injected mice and experimental controls. Results: As reported previously, kainate-injected mice exhibited two types of highly frequent electrographic seizures: high-voltage sharp waves, which were often monomorphic, and polymorphic hippocampal paroxysmal discharges. In addition, generalized convulsive clinical seizures were infrequently observed. None of these electrographic or electroclinical seizures were observed in sham controls. The only infrequently observed EEG abnormalities in sham controls were isolated spikes or spike clusters, which were also recorded in epileptic mice. Significance: This study rigorously demonstrates, by explicit comparison with the EEGs of sham controls, that the nonconvulsive paroxysmal events observed in this model are consequences of the induced epilepsy and not features of the EEG expected to be seen in some experimental control mice or unintentionally induced by surgical procedures. PMID- 29588949 TI - Understanding the burden of focal epilepsy as a function of seizure frequency in the United States, Europe, and Brazil. AB - Objective: To understand the current burden of focal epilepsy (FE) as a function of seizure frequency. Methods: Patients were identified from the United States (2011, 2012, and 2013), five European countries (EU; France, Germany, Italy, Spain, United Kingdom) (2011 and 2013), and Brazil (2011 and 2012) National Health and Wellness Survey (NHWS), a nationally representative, Internet-based survey of adults (18+ years). The NHWS collected data on respondents' quality of life (QoL), health utilities, productivity loss, and healthcare resource utilization. Indirect and direct costs were calculated from the literature. Altogether, 345 of 176,093 (U.S.A.), 73 of 30,000 (United Kingdom), 53 of 30,001 (Germany), 53 of 30,000 (France), 41 of 12,011 (Spain), 37 of 17,500 (Italy), and 71 of 24,000 (Brazil) respondents self-reported a diagnosis of FE. Results: Many respondents (U.S.A.: 56.2%; 5EU: 41.6%; Brazil + 5EU: 40.5%) reported persistent seizures (>=1 per year). Over 60% to just over 71% of respondents with FE were treated with antiepileptic drugs (AEDs). In the United States, seizure frequency was associated with hospitalizations, indirect costs (ages 18-60), and total direct costs. For the 5EU and Brazil + 5EU, seizure frequency was associated with physical QoL, health utilities, activity impairment, and emergency room (ER) visits. Additional associations were observed for the 5EU on hospitalizations, indirect costs (ages 18-60), ER visit costs, and total direct costs and for Brazil + 5EU on absenteeism, overall work impairment, and provider visits. Costing was not performed for Brazil + 5EU. Significance: Around half of the patients had persistent seizures despite most taking an AED in this 2011-2013 dataset. The results support the hypothesis that reducing seizures can improve productivity and reduce resource utilization and associated costs. Regional differences may reflect differences in healthcare systems and selected patient populations. Overall, the results suggest that additional treatment options are needed to improve seizure control and reduce related costs. PMID- 29588948 TI - Adverse perinatal events, treatment gap, and positive family history linked to the high burden of active convulsive epilepsy in Uganda: A population-based study. AB - Objective: To determine the prevalence of active convulsive epilepsy (ACE) and describe the clinical characteristics and associated factors among a rural Ugandan population. Methods: The entire population in Iganga/Mayuge Health Demographic Surveillance Site (IM-HDSS) was screened using two questions about seizures during a door-to-door census exercise. Those who screened positive were assessed by a clinician to confirm diagnosis of epilepsy. A case control study with the patients diagnosed with ACE as the cases and age/sex-matched controls in a ratio of 1:1 was conducted. Results: A total of 64,172 (92.8%) IM-HDSS residents, with a median age of 15.0 years (interquartile range [IQR]: 8.0-29.0), were screened for epilepsy. There were 152 confirmed ACE cases, with a prevalence of 10.3/1,000 (95% confidence interval [CI]: 9.5-11.1) adjusted for nonresponse and screening sensitivity. Prevalence declined with age, with the highest prevalence in the 0-5 years age group. In an analysis of n = 241 that included cases not identified in the survey, nearly 70% were unaware of their diagnosis. Seizures were mostly of focal onset in 193 (80%), with poor electroencephalogram (EEG) agreement with seizure semiology. Antiepileptic drug use was rare, noted in 21.2% (95% CI: 16.5-25.8), and 119 (49.3%) reported using traditional medicines. History of an abnormal antenatal period (adjusted odds ratio [aOR] 10.28; 95%CI 1.26-83.45; p = 0.029) and difficulties in feeding, crying, breathing in the perinatal period (aOR 10.07; 95%CI 1.24-81.97; p = 0.031) were associated with ACE in children. In adults a family history of epilepsy (aOR 4.38 95%CI 1.77 10.81; p = 0.001) was the only factor associated with ACE. Significance: There is a considerable burden of epilepsy, low awareness, and a large treatment gap in this population of rural sub-Saharan Africa. The identification of adverse perinatal events as a risk factor for developing epilepsy in children suggests that epilepsy burden may be decreased by improving obstetric and postnatal care. PMID- 29588950 TI - Decreased functional connectivity within a language subnetwork in benign epilepsy with centrotemporal spikes. AB - Objective: Benign epilepsy with centrotemporal spikes (BECTS, also known as Rolandic epilepsy) is a common epilepsy syndrome that is associated with literacy and language impairments. The neural mechanisms of the syndrome are not known. The primary objective of this study was to test the hypothesis that functional connectivity within the language network is decreased in children with BECTS. We also tested the hypothesis that siblings of children with BECTS have similar abnormalities. Methods: Echo planar magnetic resonance (MR) imaging data were acquired from 25 children with BECTS, 12 siblings, and 20 healthy controls, at rest. After preprocessing with particular attention to intrascan motion, the mean signal was extracted from each of 90 regions of interest. Sparse, undirected graphs were constructed from adjacency matrices consisting of Spearman's rank correlation coefficients. Global and nodal graph metrics and subnetwork and pairwise connectivity were compared between groups. Results: There were no significant differences in graph metrics between groups. Children with BECTS had decreased functional connectivity relative to controls within a four-node subnetwork, which consisted of the left inferior frontal gyrus, the left superior frontal gyrus, the left supramarginal gyrus, and the right inferior parietal lobe (p = 0.04). A similar but nonsignificant decrease was also observed for the siblings. The BECTS groups had significant increases in connectivity within a five-node, five-edge frontal subnetwork. Significance: The results provide further evidence of decreased functional connectivity between key mediators of speech processing, language, and reading in children with BECTS. We hypothesize that these decreases reflect delayed lateralization of the language network and contribute to specific cognitive impairments. PMID- 29588951 TI - Magnitude and factors associated with nonadherence to antiepileptic drug treatment in Africa: A cross-sectional multisite study. AB - Objectives: The epilepsy treatment gap is large in low- and middle-income countries, but the reasons behind nonadherence to treatment with antiepileptic drugs (AEDs) across African countries remain unclear. We investigated the extent to which AEDs are not taken and associated factors in people with active convulsive epilepsy (ACE) identified in cross-sectional studies conducted in five African countries. Methods: We approached 2,192 people with a confirmed diagnosis of ACE for consent to give blood voluntarily. Participants were asked if they were taking AEDs, and plasma drug concentrations were measured using a fluorescence polarization immunoassay analyzer. Information about possible risk factors was collected using questionnaire-based clinical interviews. We determined factors associated with nonadherence to AED treatment in children and adults, as measured by detectable and optimal levels, using multilevel logistic regression. Results: In 1,303 samples assayed (43.7% were children), AEDs were detected in 482, but only 287 had optimal levels. Of the 1,303 samples, 532 (40.8%) were from people who had reported they were on AEDs. The overall prevalence of nonadherence to treatment was 63.1% (95% confidence interval [CI] 60.5-65.6%) as measured by detectable AED levels and 79.1% (95% CI 73.3-84.3%) as measured by optimal AED levels; self-reported nonadherence was 65.1% (95% CI 45.0 79.5%). Nonadherence was significantly (p < 0.001) more common among the children than among adults for optimal and detectable levels of AEDs, as was the self reported nonadherence. In children, lack of previous hospitalization and learning difficulties were independently associated with nonadherence to treatment. In adults, history of delivery at home, absence of burn marks, and not seeking traditional medicine were independently associated with the nonadherence to AED treatment. Significance: Only about 20% of people with epilepsy benefit fully from antiepileptic drugs in sub-Saharan Africa, according to optimum AEDs levels. Children taking AEDs should be supervised to promote compliance. PMID- 29588952 TI - Gene panel analysis for nonsyndromic cryptogenic neonatal/infantile epileptic encephalopathy. AB - Objective: Epileptic encephalopathy (EE) is a heterogeneous condition associated with deteriorations of cognitive, sensory and/or motor functions as a consequence of epileptic activity. The phenomenon is the most common and severe in infancy and early childhood. Genetic-based diagnosis in EE patients is challenging owing to genetic and phenotypic heterogeneity of numerous monogenic disorders and the fact that thousands of genes are involved in neurodevelopment. Therefore, high throughput next-generation sequencing (NGS) was used to investigate the genetic causes of non-syndromic cryptogenic neonatal/infantile EE (NIEE). Methods: We have selected a cohort of 31 patients with seizure cryptogenic NIEE and seizure onset before 24 months. All investigations including metabolic work-up, were negative. Using NGS, we distinguished a panel of 430 epilepsy-associated genes by NGS was utilized to identify possible pathogenic variants in the patients. Segregation analysis and multiple silico analysis prediction tools were used for pathogenicity assessment. The identified variants were classified as "pathogenic," "likely pathogenic" and "uncertain significance," according to the American College of Medical Genetics (ACMG) guidelines. Results: Pathogenic or likely pathogenic variants were identified in six genes (ALG13 [1], CDKL5 [2], KCNQ2 [2], PNPO [1], SCN8A [1], SLC9A6 [2]) in 9 NIEE patients (9/31; 29%). Variants of uncertain significance (VUS) were found in DNM1 and TUBA8 in 2 NIEE patients (2/31; 6%). Most phenotypes in our cohort matched with those reported cases. Significance: The diagnostic rate (29%) of pathogenic and likely pathogenic variants was comparable to the recent studies of early-onset epileptic encephalopathy, indicating that gene panel analysis through NGS is a powerful tool to investigate cryptogenic NIEE in patients. Six percent of patients had neurometabolic disorders. Some of our diagnosed cases illustrated that successful molecular investigation may allow a better treatment strategy and avoid unnecessary and even invasive investigations. Functional analysis could be performed to further study the pathogenicity of the VUS identified in DNM1 and TUBA8. PMID- 29588953 TI - Copy number variation in a hospital-based cohort of children with epilepsy. AB - Objective: To evaluate the diagnostic yield of microarray analysis in a hospital based cohort of children with seizures and to identify novel candidate genes and susceptibility loci for epilepsy. Methods: Of all children who presented with their first seizure in the University Medical Center Groningen (January 2000 through May 2013) (n = 1,368), we included 226 (17%) children who underwent microarray analysis before June 2014. All 226 children had a definite diagnosis of epilepsy. All their copy number variants (CNVs) on chromosomes 1-22 and X that contain protein-coding genes and have a prevalence of <1% in healthy controls were evaluated for their pathogenicity. Results: Children selected for microarray analysis more often had developmental problems (82% vs. 25%, p < 0.001), facial dysmorphisms (49% vs. 8%, p < 0.001), or behavioral problems (41% vs. 13%, p < 0.001) than children who were not selected. We found known clinically relevant CNVs for epilepsy in 24 of the 226 children (11%). Seventeen of these 24 children had been diagnosed with symptomatic focal epilepsy not otherwise specified (71%) and five with West syndrome (21%). Of these 24 children, many had developmental problems (100%), behavioral problems (54%) or facial dysmorphisms (46%). We further identified five novel CNVs comprising four potential candidate genes for epilepsy: MYT1L, UNC5D, SCN4B, and NRXN3. Significance: The 11% yield in our hospital-based cohort underscores the importance of microarray analysis in diagnostic evaluation of children with epilepsy. PMID- 29588954 TI - Frequent sleep-related bitemporal focal seizures in transient epileptic amnesia syndrome: Evidence from ictal video-EEG. AB - Two patients who shared similar presenting clinical features of anterograde and retrograde autobiographical amnesia typical of transient epileptic amnesia (TEA) underwent prolonged video electroencephalogram (VEEG) monitoring and were found to have sleep-activated epileptiform activity and frequent subclinical bitemporal seizures predominantly during sleep. Case 1 is a 59-year-old woman whose presenting complaint was memory impairment. Over 18 months, she had three distinct 8-h-long episodes of confusion and disorientation with persistent anterograde and retrograde autobiographical amnesia. VEEG recorded frequent interictal bitemporal sharp waves confined to sleep, and 14 subclinical seizures, also mostly during sleep. Case 2 is a 50-year-old woman with known focal epilepsy also presented with memory complaints. Over the course of 1 year, she had two discrete 2-h-long episodes of amnesia, with ongoing anterograde and retrograde autobiographical amnesia. VEEG recorded independent bitemporal sharp waves, and 14 subclinical seizures during sleep and drowsiness. Memory impairment improved in both patients with successful treatment of their seizures. Although the etiology of accelerated long-term forgetting (ALF) and remote memory impairment (RMI) in transient epileptic amnesia (TEA) is unknown, these cases suggest frequent sleep-related seizures may contribute, and they highlight the importance of video-EEG monitoring. PMID- 29588955 TI - Complex observation of scalp fast (40-150 Hz) oscillations in West syndrome and related disorders with structural brain pathology. AB - We investigated the relationship between the scalp distribution of fast (40-150 Hz) oscillations (FOs) and epileptogenic lesions in West syndrome (WS) and related disorders. Subjects were 9 pediatric patients with surgically confirmed structural epileptogenic pathology (age at initial electroencephalogram [EEG] recording: mean 7.1 months, range 1-22 months). The diagnosis was WS in 7 patients, Ohtahara syndrome in 1, and a transitional state from Ohtahara syndrome to WS in the other. In the scalp EEG data of these patients, we conservatively detected FOs, and then examined the distribution of FOs. In five patients, the scalp distribution of FOs was consistent and concordant with the lateralization of cerebral pathology. In another patient, FOs were consistently dominant over the healthy cerebral hemisphere, and the EEG was relatively low in amplitude over the pathological atrophic hemisphere. In the remaining 3 patients, the dominance of FOs was inconsistent and, in 2 of these patients, the epileptogenic hemisphere was reduced in volume, which may result from atrophy or hypoplasia. The correspondence between the scalp distribution of FOs and the epileptogenic lesion should be studied, taking the type of lesion into account. The factors affecting scalp FOs remain to be elucidated. PMID- 29588956 TI - High-frequency oscillations detected in ECoG recordings correlate with cavernous malformation and seizure-free outcome in a child with focal epilepsy: A case report. AB - Epilepsy associated with cavernous malformation (CM) often requires surgical resection of seizure focus to achieve seizure-free outcome. High-frequency oscillations (HFOs) in intracranial electroencephalogram (EEG) are reported as potential biomarkers of epileptogenic regions, but to our knowledge there are no data on the existence of HFOs in CM-caused epilepsy. Here we report our experience of the identification of the seizure focus in a 3-year-old pediatric patient with intractable epilepsy associated with CM. The electrocorticographic recordings were obtained from a 64-contact grid over 2 days in the epilepsy monitoring unit (EMU). The spatial distribution of HFOs and epileptic spikes were estimated from recording segments right after the electrode placement, during sleep and awake states separately. The HFO distribution showed consistency with the perilesional region; the location of spikes varied over days and did not correlate with the lesion. The HFO spatial distribution was more compact in sleep state and pinpointed the contacts sitting on the CM border. Following the resection of the CM and the hemosiderin ring, the patient became seizure-free. This is the first report describing HFOs in a pediatric patient with intractable epilepsy associated with CM and shows their potential in identifying the seizure focus. PMID- 29588957 TI - DRESS syndrome: A case of cross-reactivity with lacosamide? AB - A 42-year-old patient with epilepsy was admitted to the hospital for fever and generalized skin rash. He has known allergy to phenytoin. Valproate was started in 2012, but failed to control his seizure despite gradual increase in dosage. Phenobarbitone was added 16 days before admission and was stopped on admission. He was treated with beta-lactam antibiotics. The rash subsided gradually after the cessation of phenobarbitone. Lacosamide was subsequently added for seizure control. Unfortunately, he developed drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome soon after introduction of lacosamide that required the use of systemic steroid for acute hepatitis. A cross-reactivity with lacosamide was suspected in view of the rapid onset of DRESS syndrome after the initial rash resolution and soon after the introduction of lacosamide. We postulated that the rapid onset of DRESS syndrome may be related to the aromatic ring that is in common among phenytoin, phenobarbitone, and lacosamide. PMID- 29588959 TI - PNES around the world: Where we are now and how we can close the diagnosis and treatment gaps-an ILAE PNES Task Force report. AB - An international consensus clinical practice statement issued in 2011 ranked psychogenic nonepileptic seizures (PNES) among the top three neuropsychiatric problems. An ILAE PNES Task Force was founded and initially charged with summarizing the current state of the art in terms of diagnosis and treatment, resulting in two publications. The first described different levels of diagnostic certainty. The second summarized current knowledge of management approaches. The present paper summarizes an international workshop of the ILAE PNES Task Force that focused on the current understanding and management of PNES around the world. We initially provide a knowledge update about the etiology, epidemiology, and prognosis of PNES-in adults and in special patient groups, such as children, older adults, and those with intellectual disability. We then explore clinical management pathways and obstacles to optimal care for this disorder around the world by focusing on a number of countries with different cultural backgrounds and at very different stages of social and economic development (United Kingdom, U.S.A., Zambia, Georgia, China, and Japan). Although evidence-based methods for the diagnosis and treatment of PNES have now been described, and much is known about the biopsychosocial underpinnings of this disorder, this paper describes gaps in care (not only in less developed countries) that result in patients with PNES not having adequate access to healthcare provisions. A range of challenges requiring solutions tailored to different healthcare systems emerges. Continued attention to PNES by the ILAE and other national and international neurologic, psychiatric, and health organizations, along with ongoing international collaboration, should ensure that patients with PNES do not lose out as healthcare services evolve around the world. PMID- 29588960 TI - The relationship between d-beta-hydroxybutyrate blood concentrations and seizure control in children treated with the ketogenic diet for medically intractable epilepsy. AB - Objective: The ketogenic diet (KD) is a proven treatment for drug-resistant (DR) seizures in children and adolescents. However, the relationship between seizure control and the most commonly measured metabolite of the diet, the ketone body d beta-hydroxybutyrate (D-BHB), is controversial. This study was performed to clarify the relationship because specific ketone bodies may be useful as biomarkers of diet efficacy. Methods: Families of children with DR seizures were approached for participation in this open-label, prospective study when they were referred for the KD at two western Canadian children's hospitals. Inclusion criteria included documentation of DR seizures without exclusion based on age, sex, seizure, or syndrome type. Patients were excluded if they were referred for treatment of a metabolic disorder independent of seizures. Seizures were quantified via parental report and standardized as seizure frequency per 28 days. Epilepsy syndromes were identified on the basis of the medical record. Blood D BHB was determined by tandem mass spectrometry. Results: A total of 23 patients were recruited from both sites. Data from five individuals were excluded because these seizures occurred in clusters, leaving 18 patients for the primary analysis. In the latter group, a clear positive correlation was present between measures of seizure frequency and D-BHB concentrations. However, this failed to reach statistical significance, likely because of the relatively small numbers. Significance: A trend clearly exists between seizure frequency and D-BHB levels, so we should not be dissuaded by the lack of statistical significance because it possibly results from methodological techniques, especially sample size. These results call for a larger prospective study in which seizure frequency is assessed at the point of care in a standardized fashion so as to determine whether D-BHB can be used as a reliable biomarker of KD efficacy. PMID- 29588961 TI - Automated long-term EEG analysis to localize the epileptogenic zone. AB - Objective: We investigated the performance of automatic spike detection and subsequent electroencephalogram (EEG) source imaging to localize the epileptogenic zone (EZ) from long-term EEG recorded during video-EEG monitoring. Methods: In 32 patients, spikes were automatically detected in the EEG and clustered according to their morphology. The two spike clusters with most single events in each patient were averaged and localized in the brain at the half rising time and peak of the spike using EEG source imaging. On the basis of the distance from the sources to the resection and the known patient outcome after surgery, the performance of the automated EEG analysis to localize the EZ was quantified. Results: In 28 out of the 32 patients, the automatically detected spike clusters corresponded with the reported interictal findings. The median distance to the resection in patients with Engel class I outcome was 6.5 and 15 mm for spike cluster 1 and 27 and 26 mm for cluster 2, at the peak and the half rising time of the spike, respectively. Spike occurrence (cluster 1 vs. cluster 2) and spike timing (peak vs. half-rising) significantly influenced the distance to the resection (p < 0.05). For patients with Engel class II, III, and IV outcomes, the median distance increased to 36 and 36 mm for cluster 1. Localizing spike cluster 1 at the peak resulted in a sensitivity of 70% and specificity of 100%, positive prediction value (PPV) of 100%, and negative predictive value (NPV) of 53%. Including the results of spike cluster 2 led to an increased sensitivity of 79% NPV of 55% and diagnostic OR of 11.4, while the specificity dropped to 75% and the PPV to 90%. Significance: We showed that automated analysis of long-term EEG recordings results in a high sensitivity and specificity to localize the epileptogenic focus. PMID- 29588963 TI - Phenytoin as a last-resort treatment in SCN8A encephalopathy. AB - SCN8A encodes Nav1.6, one of the main voltage-gated sodium channel subunits in the brain, and SCN8A mutations lead to epileptic encephalopathy. Particular mutations render the mutant channel more susceptible to inhibition by phenytoin. Yet, the potentially severe side effects of phenytoin maintenance therapy, especially cognitive impairment, are undesirable in these already cognitively impaired patients. We describe a 5-year-old patient with SCN8A encephalopathy in whom phenytoin proved successful as emergency treatment to prevent clustering of seizures and status epilepticus, thus hospital stays. The ketogenic diet, levetiracetam, zonisamide, topiramate, and phenytoin maintenance therapy resulted in adverse reactions not previously documented in SCN8A encephalopathy. PMID- 29588962 TI - Functional variants in HCN4 and CACNA1H may contribute to genetic generalized epilepsy. AB - Objective: Genetic generalized epilepsy (GGE) encompasses seizure disorders characterized by spike-and-wave discharges (SWD) originating within thalamo cortical circuits. Hyperpolarization-activated (HCN) and T-type Ca2+ channels are key modulators of rhythmic activity in these brain regions. Here, we screened HCN4 and CACNA1H genes for potentially contributory variants and provide their functional analysis. Methods: Targeted gene sequencing was performed in 20 unrelated familial cases with different subtypes of GGE, and the results confirmed in 230 ethnically matching controls. Selected variants in CACNA1H and HCN4 were functionally assessed in tsA201 cells and Xenopus laevis oocytes, respectively. Results: We discovered a novel CACNA1H (p.G1158S) variant in two affected members of a single family. One of them also carried an HCN4 (p.P1117L) variant inherited from the unaffected mother. In a separate family, an HCN4 variant (p.E153G) was identified in one of several affected members. Voltage clamp analysis of CACNA1H (p.G1158S) revealed a small but significant gain-of function, including increased current density and a depolarizing shift of steady state inactivation. HCN4 p.P1117L and p.G153E both caused a hyperpolarizing shift in activation and reduced current amplitudes, resulting in a loss-of-function. Significance: Our results are consistent with a model suggesting cumulative contributions of subtle functional variations in ion channels to seizure susceptibility and GGE. PMID- 29588964 TI - Application of RNS in refractory epilepsy: Targeting insula. AB - Although responsive neurostimulation (RNS) is approved for treatment of resistant focal epilepsy in adults, little is known about response to treatment of specific cortical targets. We describe the experience of RNS targeting the insular lobe. We identified patients who had RNS implantation with at least one electrode within the insula between April 2014 and October 2015. We performed a retrospective review of preoperative clinical features, imaging, electrocardiogram (EEG), intraoperative electrocorticography (ECoG), and postoperative seizure outcome. Eight patients with at least 6 months of postimplant follow-up were identified. Ictal localization was inconclusive with MRI or scalp EEG findings. Intracranial EEG monitoring or intraoperative ECoG demonstrated clear ictal onsets and/or frequent interictal discharges in the insula. Four patients demonstrated overall 50-75% reduction in seizure frequency. Two patients did not show appreciable seizure improvement. One patient has experienced a 75% reduction of seizure frequency, and another is nearly seizure free postoperatively. There were no reported direct complications of insular RNS electrode placement or stimulation, though two patients had postoperative complications thought to be related to craniotomy (hydrocephalus and late infection). Our study suggests that insular RNS electrode placement in selected patients is relatively safe and that RNS treatment may benefit selected patients with insular epilepsy. PMID- 29588965 TI - Eucalyptus oil inhalation-induced seizure: A novel, underrecognized, preventable cause of acute symptomatic seizure. AB - Eucalyptus oil (EO) is an essential oil that is widely used across the globe as an over-the-counter remedy for common ailments. EO-induced seizure (EOIS) has not been recognized as an entity, and physicians rarely ask the history of exposure to eucalyptus oil when seeing a patient with first episode of seizure. Here we report 10 cases of EO inhalation-induced seizures seen over the past 2 years in three tertiary care hospitals. Eight patients had GTCS and two had CPS. We aim to raise awareness of seizures induced by exposure to eucalyptus oil. PMID- 29588966 TI - Pathogenic potential of antibodies to the GABAB receptor. AB - GABAB receptor (GABABR) autoantibodies have been detected in the serum of immunotherapy-responsive patients with autoimmune encephalitis. This study aimed to investigate the effect of immunoglobulin G (IgG) from a patient with GABABR antibodies on primary neuronal cultures and acute slices of entorhinal cortex. Primary hippocampal neuronal cultures were incubated with serum immunoglobulin from patients with GABABR or AMPA receptor (AMPAR) antibodies for up to 72 h to investigate their effect on receptor surface expression. Whole-cell patch-clamp recordings from layer III pyramidal cells of the medial entorhinal cortex were used to examine the effect on neuronal activity. GABABR surface expression was unaltered by incubation with GABABR antibodies. By contrast, after 24 h application of AMPAR antibodies, AMPARs were undetectable. However, acute application of GABABR IgG decreased both the duration of network UP states and the spike rate of pyramidal cells in the entorhinal cortex. GABABR antibodies do not appear to affect GABABRs by internalization but rather reduce excitability on the medial temporal lobe networks. This unusual mechanism of action may be exploited in rational drug development strategies. PMID- 29588968 TI - Announcing the new Epilepsia Open Prizes. PMID- 29588970 TI - Prevalence, risk factors, and neurobehavioral comorbidities of epilepsy in Kenyan children. AB - Objective: To investigate the prevalence, risk factors, clinical features, and neurobehavioral comorbidities of epilepsy and acute symptomatic seizures in school-aged children in Kilifi, Kenya. Methods: Randomly selected children (N = 11,223) were screened for epilepsy and other neurodevelopmental disorders. Those who screened positive were invited for further clinical, electroencephalographic (EEG), and neuropsychological evaluations. Prevalence was measured by dividing cases by screened population, providing Agresti-Coull confidence intervals (CIs). Prevalence ratios were computed using log binomial regression, and odds ratios (ORs) were computed using logistic regression; both were implemented with generalized linear models. Attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and other neurodevelopmental impairments were assessed in cases and controls. Results: Prevalence of lifetime epilepsy was 20.9 per 1,000 (95% CI = 18.4-23.7), and that of active epilepsy was 11.5 per 1,000 (95% CI = 9.7-13.6). Prevalence of acute symptomatic seizures was 68.8 per 1,000 (95% CI = 64.2-73.6). Acute symptomatic seizures preceded a diagnosis of epilepsy in 8% of children. Of 98 children diagnosed with epilepsy, focal seizures were seen in 79%, abnormal EEG was seen in 39%, and 83% were not receiving antiepileptic drugs. Childhood absence epilepsy and Lennox-Gastaut epilepsy were the most easily identifiable epilepsy syndromes. Perinatal complications, previous hospitalization, geophagia, and snoring were risk factors for epilepsy. Family history of seizures, abnormal pregnancy, previous hospitalization, and snoring were risk factors for acute symptomatic seizures. Neurobehavioral comorbidities were present in 54% of subjects with lifetime epilepsy and in 3% of controls, with associations for individual comorbidities being statistically significant: ADHD (OR = 14.55, 95% CI = 7.54-28.06), ASD (OR = 36.83, 95% CI = 7.97-170.14), and cognitive impairments (OR = 14.55, 95% CI = 3.52-60.14). Significance: The burden of seizure disorders in this area is higher than in locations in high-income countries, and can be reduced by preventing risk factors. A comprehensive management plan for neurobehavioral comorbidities of epilepsy should be incorporated into standard epilepsy care. PMID- 29588969 TI - Neurostimulation as a promising epilepsy therapy. AB - The revolution in theory, swift technological developments, and invention of new devices have driven tremendous progress in neurostimulation as a third-line treatment for epilepsy. Over the past decades, neurostimulation took its place in the field of epilepsy as an advanced treatment technique and opened up a new world. Numerous animal studies have proven the physical efficacy of stimulation of the brain and peripheral nerves. Based on this optimistic fundamental research, new advanced techniques are being explored in clinical practice. Over the past century, drawing on the benefits brought about by vagus nerve stimulation for the treatment of epilepsy, various new neurostimulation modalities have been developed to control seizures. Clinical studies including case reports, case series, and clinical trials have been booming in the past several years. This article gives a comprehensive review of most of these clinical studies. In addition to highlighting the advantages of neurostimulation for the treatment of epilepsy, concerns with this modality and future development directions are also discussed. The biggest advantage of neurostimulation over pharmacological treatments for epilepsy is the modulation of the epilepsy network by delivering stimuli at a specific target or the "hub." Conversely, however, a lack of knowledge of epilepsy networks and the mechanisms of neurostimulation may hinder further development. Therefore, theoretical research on the mechanism of epileptogenesis and epilepsy networks is needed in the future. Within the multiple modalities of neuromodulation, the final choice should be made after full discussion with a multidisciplinary team at a presurgical conference. Furthermore, the establishment of a neurostimulation system with standardized parameters and rigorous guidelines is another important issue. To achieve this goal, a worldwide collaboration of epilepsy centers is also suggested in the future. PMID- 29588971 TI - Personalized safety measures reduce the adverse event rate of long-term video EEG. AB - Objective: Safety in epilepsy monitoring units (EMUs) has become an increasing concern because adverse events occur in up to 10% of patients undergoing long term video EEG in EMUs. The aim of this study was to assess the effectiveness of a specific safety protocol in an EMU. Methods: We retrospectively assessed the adverse event rates in a group without (group 1, 84-month period, Innsbruck, Austria) and a group with (group 2, 33-month period, Salzburg, Austria) personalized safety measures utilizing a standardized protocol for long-term epilepsy monitoring in high-risk patients. Differences in adverse event rates during and after long-term video EEG between the two groups were calculated and compared. Results: In group 1, 44/507 (9%, 95% confidence interval [CI] 6.5 11.5%) patients experienced 53 adverse events: 20/507 (4%, 95% CI 2.6-6.0%) patients had psychiatric events, 15/507 (3%, 95% CI 1.8-4.8%) patients sustained a total of 19 injuries during seizures, and 10/507 (2%, 95% CI 1.1-3.6%) patients had 13 episodes of status epilepticus; one adverse event was treatment-related (valproic acid-induced encephalopathy; 1/507, 0.2%, 95% CI 0.0-1.1%). By using the new safety protocol in group 2, the adverse event rate was only 5% (95% CI 3.4-7.6%; 30 adverse events in 26/491; 45% reduction; p = 0.036), in contrast. These events included 13 psychiatric complications in 13/491 (2%, 95% CI 1.6 4.5%, p = 0.252) patients, 12 seizure-related injuries in 9/491 (2%, 95% CI 1.0 3.4%, p = 0.250) patients, and 5 episodes of status epilepticus in 4/491 (1%, 95% CI 0.3-2.1%, p = 0.120) patients. Significance: Implementation of personalized safety measures in high-risk patients resulted in a clinically relevant reduction of adverse events in the EMU. Safety protocols are a valid tool to reduce the occurrence of adverse events in EMUs. PMID- 29588972 TI - Safety and tolerability of lacosamide monotherapy in the elderly: A subgroup analysis from lacosamide trials in diabetic neuropathic pain. AB - Objective: To assess the safety profile of lacosamide monotherapy in elderly (>=65 years) subjects with diabetic neuropathic pain (DNP). Methods: Of 1,863 DNP subjects in double-blind, randomized, placebo-controlled trials of lacosamide monotherapy (NCT00861445, NCT00235469, NCT00238524, NCT00135109, NCT00350103), 502 were elderly. Safety data from elderly subjects were compared with that of younger subjects (<65 years) within these DNP trials. It should be noted that lacosamide is approved for the treatment of focal (partial-onset) seizures; it is not approved/recommended for the treatment of DNP. Results: Overall, cardiovascular diseases were prevalent in the DNP population, as was the use of cardiac, blood pressure, diabetes, and cholesterol-lowering medications among both young and elderly subjects. The most frequently reported adverse events (AEs) for lacosamide monotherapy (200, 400, and 600 mg/day combined) in elderly versus younger subjects were dizziness (16.2% vs. 13.2%), nausea (10.0% vs. 9.4%), and headache (8.0% vs. 8.7%). Incidences of cardiac disorder AEs were higher in elderly versus younger subjects receiving placebo (6.2% vs. 3.9%), lacosamide 200 (4.8% vs. 3.3%), lacosamide 400 (7.0% vs. 4.1%), and lacosamide 600 mg/day (7.7% vs. 4.0%). Discontinuation rates because of any AE in the elderly versus younger subjects were similar for placebo (8.8% vs. 7.0%) and lacosamide 200 mg/day (9.6% vs. 11.9%) and higher for lacosamide 400 (25.1% vs. 10.8%) and lacosamide 600 mg/day (52.7% vs. 28.3%). Significance: Lacosamide monotherapy was well tolerated in elderly subjects with DNP, with an overall AE profile consistent with that reported in epilepsy trials. PMID- 29588973 TI - Multimodal, automated detection of nocturnal motor seizures at home: Is a reliable seizure detector feasible? AB - Objective: Automated seizure detection and alarming could improve quality of life and potentially prevent sudden, unexpected death in patients with severe epilepsy. As currently available systems focus on tonic-clonic seizures, we want to detect a broader range of seizure types, including tonic, hypermotor, and clusters of seizures. Methods: In this multicenter, prospective cohort study, the nonelectroencephalographic (non-EEG) signals heart rate and accelerometry were measured during the night in patients undergoing a diagnostic video-EEG examination. Based on clinical video-EEG data, seizures were classified and categorized as clinically urgent or not. Seizures included for analysis were tonic, tonic-clonic, hypermotor, and clusters of short myoclonic/tonic seizures. Features reflecting physiological changes in heart rate and movement were extracted. Detection algorithms were developed based on stepwise fulfillment of conditions during increases in either feature. A training set was used for development of algorithms, and an independent test set was used for assessing performance. Results: Ninety-five patients were included, but due to sensor failures, data from only 43 (of whom 23 patients had 86 seizures, representing 402 h of data) could be used for analysis. The algorithms yield acceptable sensitivities, especially for clinically urgent seizures (sensitivity = 71-87%), but produce high false alarm rates (2.3-5.7 per night, positive predictive value = 25-43%). There was a large variation in the number of false alarms per patient. Significance: It seems feasible to develop a detector with high sensitivity, but false alarm rates are too high for use in clinical practice. For further optimization, personalization of algorithms may be necessary. PMID- 29588974 TI - Seizures, electroencephalographic abnormalities, and outcome of ischemic stroke patients. AB - Objective: Seizures and electroencephalographic (EEG) abnormalities have been associated with unfavorable stroke functional outcome. However, this association may depend on clinical and imaging stroke severity. We set out to analyze whether epileptic seizures and early EEG abnormalities are predictors of stroke outcome after adjustment for age and clinical/imaging infarct severity. Methods: A prospective study was made on consecutive and previously independent acute stroke patients with a National Institutes of Health Stroke Scale (NIHSS) score >= 4 on admission and an acute anterior circulation ischemic lesion on brain imaging. All patients underwent standardized clinical and diagnostic assessment during admission and after discharge, and were followed for 12 months. Video-EEG (<60 min) was performed in the first 72 h. The Alberta Stroke Program Early CT Score quantified middle cerebral artery infarct size. The outcomes in this study were an unfavorable functional outcome (modified Rankin Scale [mRS] >= 3) and death (mRS = 6) at discharge and 12 months after stroke. Results: Unfavorable outcome at discharge was independently associated with NIHSS score (p = 0.001), EEG background activity slowing (p < 0.001), and asymmetry (p < 0.001). Unfavorable outcome 1 year after stroke was independently associated with age (p = 0.001), NIHSS score (p < 0.001), remote symptomatic seizures (p = 0.046), EEG background activity slowing (p < 0.001), and asymmetry (p < 0.001). Death in the first year after stroke was independently associated with age (p = 0.028), NIHSS score (p = 0.001), acute symptomatic seizures (p = 0.015), and EEG suppression (p = 0.019). Significance: Acute symptomatic seizures were independent predictors of vital outcome and remote symptomatic seizures of functional outcome in the first year after stroke. Therefore, their recognition and prevention strategies may be clinically relevant. Early EEG abnormalities were independent predictors and comparable to age and early clinical/imaging infarct severity in stroke functional outcome discrimination, reflecting the concept that EEG is a sensitive and robust method in the functional assessment of the brain. PMID- 29588975 TI - A comparison of waiting times for assessment and epilepsy surgery between a Canadian and a Mexican referral center. AB - Objective: To provide a comprehensive transnational overview of wait times for epilepsy surgery in Canada and Mexico. Methods: We reviewed all cases referred for epilepsy surgery between 2007 and 2015 at the Saskatchewan Epilepsy Program Royal University Hospital (SEP) (n = 70; Saskatoon, Canada) and the National Institute of Neurology and Neurosurgery (NINN) (n = 76; Mexico City, Mexico) and compared wait times, calculated as the time from diagnosis of epilepsy on assessment at an epilepsy center to epilepsy surgery. Results: Mean wait times were similar across centers. Mean patient age was 37.4 +/- 9 years (NINN) and 36.7 +/- 13.2 years (SEP). The mean time from epilepsy diagnosis to referral was 18.9 (NINN) and 16.9 years (SEP), p = 0.30; first consult with the epileptologist, 19.7 (NINN) and 17.4 years (p = 0.23); neuropsychology consult, 21.4 (NINN) and 17.9 years (SEP); video electroencephalogram (video-EEG) telemetry, 21.1 (NINN) and 18.6 months (SEP); initial neurosurgical consult, 21.9 (NINN) and 19.1 years (SEP) (p = 0.35); and epilepsy surgery, 19.7 (NINN) and 19.6 years (SEP) (p = 0.29). Significance: This is the first study to compare wait times between Canada and Mexico. Despite disparity in their health delivery systems and financial resources, surgical wait times appeared to be protracted in both nations, confirming that delayed treatment is a universal problem that requires collaborative scrutiny. PMID- 29588976 TI - Incidence of seizure exacerbation and seizures reported as adverse events during adjunctive treatment with eslicarbazepine acetate: A pooled analysis of three Phase III controlled trials. AB - Objective: To investigate whether adjunctive eslicarbazepine acetate (ESL) could lead to exacerbation of seizures in some patients. Methods: Post-hoc analysis of data pooled from three Phase III trials of adjunctive ESL (studies 301, 302, and 304) for refractory partial-onset seizures (POS). Following an 8-week baseline period, patients were randomized to receive placebo or ESL 400, 800, or 1,200 mg once daily (2-week titration, 12-week maintenance, 2-4 week tapering-off periods). Patient seizure diary data and seizure treatment-emergent adverse event (TEAE) reports were pooled for analysis. Results: The modified intent-to-treat and safety populations comprised 1,410 patients and 1,447 patients, respectively. Titration period: Compared with placebo (32/21%), significantly smaller proportions of patients taking ESL 800 mg (20/15%) and 1,200 mg (22/12%) had a >=25/>=50% increase in standardized seizure frequency (SSF) from baseline; there was no significant difference between placebo and ESL 400 mg. Maintenance period: Compared with placebo (20%), significantly smaller proportions of patients taking ESL (400 mg, 12%; 800 mg, 12%; 1,200 mg, 14%) had an increase in SSF >=25%. When evaluating >=50% increases in SSF, only ESL 800 mg (7%) was significantly different from placebo (12%). Some patients had no secondarily generalized tonic clonic (sGTC) seizures during baseline but had >=1 sGTC seizure during maintenance treatment (placebo, 11%; ESL 400 mg, 5%; 800 mg, 10%; 1,200 mg, 5%). Fewer patients had a >=25% increase in sGTC seizure frequency with ESL (400 mg, 11%; 800 mg, 9%; 1,200 mg, 14%) versus placebo (19%). The incidence of seizures reported as TEAEs was low in all treatment groups; incidences were generally lower with ESL versus placebo. Tapering-off period: Similar proportions of patients taking ESL and placebo had a >=25/>=50% increase in SSF. Seizure TEAE incidence was numerically higher with ESL versus placebo. Significance: Treatment with adjunctive ESL does not appear to aggravate POS or sGTC seizures. PMID- 29588977 TI - Simultaneous occurrence of nonepileptic and epileptic seizures during a single period of in-patient video-electroencephalographic monitoring. AB - Epilepsy and psychogenic nonepileptic seizures (PNES) can coexist and may present in two forms: sequential and simultaneous. In sequential presentations, epileptic seizures (ES) are treated and PNES emerge later. Simultaneous recording of ES and PNES by video-electroencephalogram (vEEG) is less well described. We retrospectively reviewed all patients diagnosed with PNES by vEEG following standard seizure induction practices over a 21-month period. Within this cohort, we established the prevalence of coexisting epilepsy using clinical and electrographic data acquired from our epilepsy-specific patient record. We identified patients with simultaneous PNES and ES recorded during a single vEEG admission, establishing the frequency and emergent timing of each type. Of our 262 monitored patients, 59 were diagnosed with PNES. Nineteen of the patients with PNES had coexisting epilepsy (prevalence rate of 7.3% or 32% of those with PNES). Sixteen patients had PNES and ES recorded during the same admission, and the remaining three patients had sequential PNES following successful treatment of ES. PNES occurred earlier (mean, within 1.21 days), with ES occurring later (mean, within 4.86 days). The simultaneous occurrence of PNES and ES recorded during a single admission is more common than previously reported. Identifying this group of patients may require a significantly longer period of vEEG monitoring and a detailed analysis of each individual's historical seizure events. PMID- 29588978 TI - Topography of generalized periodic epileptiform discharges in postanoxic nonconvulsive status epilepticus. AB - We studied slow (<=2.5 Hz) nonevolving generalized periodic epileptiform discharges (GPEDs) in the electroencephalogram (EEG) of comatose patients after cardiac arrest (CA) in search of evidence that could assist early diagnosis of possible hypoxic nonconvulsive status epilepticus (NCSE) and its differentiation from terminal brain anoxia (BA), which can present with a similar EEG pattern. We investigated the topography of the GPEDs in the first post-CA EEGs of 13 patients, using voltage-mapping, and compared findings between two patients with NCSE and GPEDs > 2.5 Hz (group 1), and 11 with GPEDs <= 2 Hz, of whom six had possible NCSE (group 2) and five had terminal BA (group 3). Voltage mapping showed frontal maximum for the negative phase of the GPEDs in all patients of groups 1 and 2, but not in any of the patients of group 3, who invariably showed maximization of the negative phase posteriorly. Morphology, amplitude, and duration of the GPEDs varied across the groups, without distinctive features for possible NCSE. These findings provide evidence that, in hypoxic coma after CA with slow GPEDs, anterior topography of the maximum GPED negativity on voltage mapping may be a distinctive biomarker for possible NCSE contributing to the coma. PMID- 29588979 TI - Claustrum hyperintensities: A potential clue to autoimmune epilepsy. AB - In a cohort of 34 patients with autoimmune limbic encephalitis and/or epilepsy, we identified 4 patients exhibiting claustrum fluid-attenuated inversion recovery (FLAIR) hyperintensities. All 4 patients presented with explosive onset of seizures and developed medically intractable epilepsy, and 2 exhibited a marked response to immunotherapy. Associated features included cognitive and behavioral disturbances (4/4), cerebrospinal fluid (CSF) lymphocytic pleocytosis (3/4), and a neural autoantibody (2/4). Electroencephalogram (EEG) features consisted of slow wave activity and epileptiform discharges in frontal and parasagittal regions, where ictal patterns were captured in 1 patient. In 1 patient, magnetoencephalographic source imaging of interictal spikes revealed dipole sources in anterior insular or subinsular localizations, mirroring claustrum FLAIR hyperintensities, which developed after a short lag from presentation and resolved in all but 1 patient. These MRI abnormalities were isolated (2/4) or associated with mesial temporal hyperintensities (2/4). Claustrum FLAIR hyperintensities may be a useful MRI marker of autoimmune epilepsy. PMID- 29588980 TI - Novel bandlike signal abnormality suggestive of heterotopia in patient with a KCNQ1 frameshift mutation. AB - Malformations of cortical development are associated with epilepsy and cognitive dysfunction, and can occur in patients with SCN1A ion channel mutations. We report a novel and subtle bandlike subcortical heterotopia on integrated positron emission tomography-magnetic resonance imaging ( PET-MRI) in a patient with treatment-resistant epilepsy due to a de novo KCNQ1 frameshift mutation. Our case highlights the potential for other channel mutations to cause both epilepsy and cortical malformations. Further scrutiny of high contrast resolution MRI studies is warranted for patients with KCNQ1 and other epilepsy genes to further define their extended phenotype. PMID- 29588983 TI - Ketogenic diet for treatment of intractable epilepsy in adults: A meta-analysis of observational studies. AB - The ketogenic diet (KD) is an effective treatment for children with drug resistant epilepsy and has been widely used in young children. Adult patients with intractable epilepsy would also benefit from this dietary treatment. However, only a few studies have been published, and the use of the KD in intractable epilepsy in adults has been limited. This meta-analysis summarized the findings of the relevant published studies to identify the efficacy of the KD for the treatment of intractable epilepsy in adults. In this meta-analysis, PubMed, Embase, and Cochrane Library were used for searching studies concerning the effects of the KD and its major subtypes with intractable epilepsy in adults published up to January 10, 2017. The primary outcomes were seizure freedom, seizure reduction by 50% or more, and seizure reduction by <50%. The quality of the methodology of the observational studies was reviewed by using the Newcastle Ottawa Scale. We identified 402 articles, of which, 16 studies including 338 patients met the inclusion criteria. The results of the meta-analysis showed that the combined efficacy rates of all the symptoms of seizure freedom, seizure reduction by 50% or more, and seizure reduction below 50% in adults with intractable epilepsy were 13%, 53%, and 27%, respectively. The adverse reactions of the KD were mild, whereas low glycemic index diet (LGID) and low-dose fish oil diet (LFOD) may have fewer side effects. Weight loss, high level of low-density lipoprotein, and elevated total cholesterol were most frequent. The meta-analysis indicates that the KD for refractory epilepsy in adults is a well-tolerated treatment and that its side effects are acceptable, which show that the KD is a promising treatment in adult intractable epilepsy. Further research is needed to assess which type of diet or ratio is more effective in the KD treatment. PMID- 29588984 TI - Effect of neurostimulation on cognition and mood in refractory epilepsy. AB - Epilepsy is a common, debilitating neurological disorder characterized by recurrent seizures. Mood disorders and cognitive deficits are common comorbidities in epilepsy that, like seizures, profoundly influence quality of life and can be difficult to treat. For patients with refractory epilepsy who are not candidates for resection, neurostimulation, the electrical modulation of epileptogenic brain tissue, is an emerging treatment alternative. Several forms of neurostimulation are currently available, and therapy selection hinges on relative efficacy for seizure control and amelioration of neuropsychiatric comorbidities. Here, we review the current evidence for how invasive and noninvasive neurostimulation therapies affect mood and cognition in persons with epilepsy. Invasive therapies include vagus nerve stimulation (VNS), deep brain stimulation (DBS), and responsive neurostimulation (RNS). Noninvasive therapies include trigeminal nerve stimulation (TNS), repetitive transcranial magnetic stimulation (rTMS), and transcranial direct current stimulation (tDCS). Overall, current evidence supports stable cognition and mood with all neurostimulation therapies, although there is some evidence that cognition and mood may improve with invasive forms of neurostimulation. More research is required to optimize the effects of neurostimulation for improvements in cognition and mood. PMID- 29588985 TI - Ketogenic parenteral nutrition in 17 pediatric patients with epilepsy. AB - Objective: Ketogenic parenteral nutrition (kPN) is indicated when enteral intake is temporarily limited or impossible, but evidence-based prescriptions are lacking. Objective was to evaluate the efficacy and safety of kPN in children with epileptic encephalopathies using a new computer-based algorithm for accurate component calculating. Methods: Children with epilepsy receiving kPN were included. A computer-based algorithm was established on the basis of guidelines of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN): fat intake not exceeding 4 g/kg/day, age-adequate supply of protein, electrolytes, vitamins, and trace elements, but reduced carbohydrates. Primary outcome was successfully reaching relevant ketosis, defined as beta hydroxybutyrate plasma level of >= 2 mmol/L. Efficacy was defined as seizure reduction >=50% in de novo kPN and maintenance of response in children already on a ketogenic diet (KD). Safety was assessed by adverse effects, laboratory findings, and the appropriateness of nutritional intake. Results: Seventeen children (median 1.84 years) were studied, of which 76% (13/17) were already on an oral ketogenic diet. Indications for kPN were surgery, status epilepticus, vomiting, food refusal, and introduction of enteral feeding in neonates. The parenteral fat/nonfat ratio was mean 0.9 (+/-0.3; range 0.6-1.5). Relevant ketosis was reached in 10 children (median 2.9 mmol/L), but not in 7 (median = 1.4 mmol/L). In de novo kPN, significant response was observed in 50% (2/4); in patients previously responding to the KD (77%, 10/13), response was maintained. A significant correlation between the degree of ketosis and seizure reduction (correlation coefficient = 0.691; p = .002) was observed. Only mild and transient adverse events occurred during kPN. Significance: KPN with fat intake of 3.5-4.0 g/kg/day was safe and effective. KPN was tailored according to guidelines and individual nutritional needs. In nearly half of the patients, ketosis was lower than during oral KD. Despite this, seizures remained controlled. PMID- 29588986 TI - Young people with epilepsy have an increased risk of eating disorder and poor quality diet. AB - Objective: To investigate whether adolescents with epilepsy are at increased risk of having self-reported eating disorder symptoms and poor quality diet compared to young people from the general population. Methods: We used data from the Health Profile for Children and Youth in Akershus Study, a cross-sectional population-based study based on a voluntary self-reported questionnaire. There were 19,995 participants (response rate 85%) aged 13-19 years; 247 (1.2%) reported a lifetime diagnosis of epilepsy. Odds ratios (OR) and 95% confidence intervals (CI) for eating disorders, unhealthy diet, dieting, satisfaction with looks, and participation in sports were estimated by using a logistic regression model. All estimates were adjusted for single parents and poor family economy. Results: Children and adolescents with epilepsy had more eating disorders than their peers (OR 1.8, CI 1.0-3.0, p = 0.03). They were less satisfied with their own appearance (OR 0.7, CI 0.5-0.9, p = 0.02), and they eat more unhealthily (OR 1.7, CI 1.3-2.2, p = 0.001). Males with epilepsy were more likely to have been dieting (OR 3.1, CI 1.2-7.9, p = 0.02) and less satisfied with their own appearance (OR 0.4, CI 0.3-0.7, p < 0.001). Females with epilepsy were more likely to eat unhealthily (OR 1.7, CI 1.1-2.5, p = 0.01). Significance: Adolescents with epilepsy are at increased risk of having eating disorder symptoms. They eat less healthily and are less satisfied with their looks. Health workers should be aware of this and bring diet and lifestyle into the dialogue with young people with epilepsy. PMID- 29588987 TI - Single-item measure for assessing quality of life in children with drug-resistant epilepsy. AB - Objective: The current study investigated the psychometric properties of a single item quality of life (QOL) measure, the Global Quality of Life in Childhood Epilepsy question (G-QOLCE), in children with drug-resistant epilepsy. Method: Data came from the Impact of Pediatric Epilepsy Surgery on Health-Related Quality of Life Study (PESQOL), a multicenter prospective cohort study (n = 118) with observations collected at baseline and at 6 months of follow-up on children aged 4-18 years. QOL was measured with the QOLCE-76 and KIDSCREEN-27. The G-QOLCE was an overall QOL question derived from the QOLCE-76. Construct validity and reliability were assessed with Spearman's correlation and intraclass correlation coefficient (ICC). Responsiveness was examined through distribution-based and anchor-based methods. Results: The G-QOLCE showed moderate (r >= 0.30) to strong (r >= 0.50) correlations with composite scores, and most subscales of the QOLCE 76 and KIDSCREEN-27 at baseline and 6-month follow-up. The G-QOLCE had moderate test-retest reliability (ICC range: 0.49-0.72) and was able to detect clinically important change in patients' QOL (standardized response mean: 0.38; probability of change: 0.65; Guyatt's responsiveness statistics: 0.62 and 0.78). Caregiver anxiety and family functioning contributed most strongly to G-QOLCE scores over time. Significance: Results offer promising preliminary evidence regarding the validity, reliability, and responsiveness of the proposed single-item QOL measure. The G-QOLCE is a potentially useful tool that can be feasibly administered in a busy clinical setting to evaluate clinical status and impact of treatment outcomes in pediatric epilepsy. PMID- 29588988 TI - Repetitive transcranial magnetic stimulation for the treatment of drug-resistant epilepsy: A systematic review and individual participant data meta-analysis of real-world evidence. AB - Objective: To perform a systematic review and meta-analysis of real-world evidence for the use of low-frequency repetitive transcranial magnetic stimulation (rTMS) in the treatment of drug-resistant epilepsy. Methods: We systematically searched PubMed, Scopus, Medline, and clinicaltrials.gov for all relevant articles. Relevant patient and stimulation predictors as well as seizure outcomes were assessed. For studies with and without individual participant data (IPD), the primary outcomes were the rate of "favorable response" (reduction in seizure frequency >=50%) and pooled event rate of mean reduction in seizure frequency, respectively. Outcomes were assessed with comparative statistics and random-effects meta-analysis models. Results: Of 3,477 identified articles, 12 met eligibility and were included in this review. We were able to obtain IPD for 5 articles constituting 34 participants. Univariate analysis on IPD identified greater favorable response event rates between participants with temporal seizure focus versus extratemporal (50% vs. 14%, p = 0.045) and between participants who were stimulated with a figure-8 coil versus other types (47% vs. 0%, p = 0.01). We also performed study-level meta-analysis on the remaining 7 studies without IPD, which included 212 participants. The pooled mean event rate of 50% seizure reduction using low-frequency rTMS was 30% (95% confidence interval [CI] 12-57%). Sensitivity analysis revealed that studies with a mean age <=21 years and studies using targeted stimulation had the highest seizure reduction rates compared to studies with a mean age >21 years (69% vs. 18%) and not using a targeted stimulation (47% vs. 14-20%). Moreover, we identified high interstudy heterogeneity, moderate study bias, and high publication bias. Significance: Real world evidence suggests that low-frequency rTMS using a figure-8 coil may be an effective therapy for the treatment of drug-resistant epilepsy in pediatric patients. This meta-analysis can inform the design and expedite recruitment of a subsequent randomized clinical trial. PMID- 29588989 TI - Psychogenic non-epileptic seizures among patients with functional neurological disorder: A case series from a Tanzanian referral hospital and literature review. AB - Objective: Functional neurological disorders (FNDs) and psychogenic nonepileptic seizures (PNES) are likely as common in Sub-Saharan Africa (SSA) as in the rest of the world, but there is a dearth of literature on the epidemiology and clinical presentation of these disorders in Africa. The purpose of this paper is to describe a case series of FNDs presenting to a referral hospital in SSA. In addition, we review the existing literature on FNDs in Africa. Methods: A hospital-based retrospective cross-sectional study was conducted to determine the prevalence, epidemiology, and clinical phenotype of FNDs and PNES in a referral hospital in Northern Tanzania over a 6-year period (2007-2013). Results: Of 2,040 patients presenting with neurological complaints, 44 (2.2%) were diagnosed with FNDs. Half (n = 22) had the clinical presentation of PNES. Age of presentation for FNDs and PNES peaked in the teen years 12-19 (n = 21 48%; and n = 14, 63%, respectively), and the majority were female (n = 30, 68%; and n = 14, 63%, respectively). The majority presented acutely with short-lived and self-limiting symptoms (only 2 recurrent cases). Literature review revealed multiple reports of "mass hysteria" in SSA often meeting the clinical criteria of epidemic FNDs. Significance: FNDs and PNES occur in Africa with age and gender distribution comparable to that found elsewhere. Although the percentage of FND cases overall was relatively low (2.2%), it is likely to be an underestimate because not all cases were recorded, and cases may be appropriately managed locally before patients are referred to a hospital. PNES was the most common phenotype of FNDs reported, and the African phenotype may be short-lived and self-limiting rather than chronic and recurrent, as reported elsewhere in the world. PNES presentations may also occur in clusters, which may have cultural significance in Africa. FNDs in Africa appear to be underreported, particularly over the last 30 years. PMID- 29588990 TI - Time to push the age limit: Epilepsy surgery in patients 60 years or older. AB - Objective: To summarize the existing literature on resective epilepsy surgery (RES) in older adults (>=60 years old) and examine seizure and neuropsychological outcomes in a single-center large cohort of older adults undergoing RES and their comparison to a consecutive, younger (25- to45-year-old) adult population who underwent RES in routine clinical practice. Methods: First, a comprehensive literature review was performed. Then, we identified older adults who underwent RES at our center (2000-2015). Outcome analysis was performed on patients who had >=1 year of clinical follow-up. A younger cohort of patients who underwent RES during the same period was selected for comparison. The 2 groups were compared with respect to demographic and disease variables as well as key clinical outcomes. Results: Seizure outcomes on 58 older patients were reported in existing literature; 72% achieved Engel class I outcome >=1 year postoperatively. Sixty-four older adults underwent RES at our center, accounting for 2.8% of all RES during the study period. A total of 51 older adults (Mage = 65) among them had >=1-year clinical follow-up; 80% achieved Engel I outcome after a mean follow up of 3.2 years. This was comparable to the 68% Engel class I outcome among 50 consecutive younger adults, despite later age of onset, longer epilepsy duration, and more comorbidities (all p < 0.001) among older adults. The majority (86%) of older adults were referred to our center after years of suffering from drug resistant epilepsy. There were no group differences in surgical complications. However, 1 older adult passed away post-RES. There was no difference in post-RES neuropsychological outcomes compared to younger adults, except significantly higher number of older adults showed a decline in confrontational naming. Significance: RES in well-selected older adults is a safe and effective therapy, and advanced age should not preclude consideration of surgical therapy in older adults with pharmacoresistant epilepsy. PMID- 29588991 TI - Early-onset epileptic encephalopathy and severe developmental delay in an association with de novo double mutations in NF1 and MAGEL2. AB - Advance in the exome-wide sequencing analysis contributes to identifying hundreds of genes that are associated with early-onset epileptic encephalopathy and neurodevelopmental disorders. On the basis of massive sequencing data, functional interactions among different genes are suggested to explain the common molecular pathway underlying the pathogenic process of these disorders. However, the relevance of such interactions with the phenotypic severity or variety in an affected individual remains elusive. In this report, we present a 45-year-old woman with neurofibromatosis type 1 (NF1), infantile-onset epileptic encephalopathy, and severe developmental delay. Whole-exome sequencing identified de novo pathogenic mutations in NF1 and the Schaaf-Yang syndrome-associated gene, MAGEL2. Literature-curated interaction data predicted that NF1 and MAGEL2 proteins were closely connected in this network via their common interacting proteins. Direct conversion of fibroblasts into neurons in vitro showed that neuronal cells from 9 patients with NF1 expressed significantly lower levels of MAGEL2 (54%, p = 0.0047) than those from healthy individuals. These data provide the first evidence that pathogenic mutations of NF1 deregulate the expression of other neurodevelopmental disease-associated genes. De novo mutations in multiple genes may lead to severe developmental phenotypes through their cumulative effects or synergistic interactions. PMID- 29588992 TI - Are doses of lamotrigine or levetiracetam adjusted during pregnancy? AB - Subtherapeutic levels of lamotrigine and levetiracetam are more likely to occur during pregnancy owing to the effect of pregnancy on their pharmacokinetics. This can lead to suboptimal control of epilepsy, and guidelines recommend proactive dose adjustment in the second and third trimesters alongside therapeutic drug monitoring (TDM). This retrospective cohort study using administrative databases aimed to investigate whether prescribers adjust the dose of lamotrigine or levetiracetam during and after pregnancy and whether TDM is used to manage dose adjustment. In 460 individual pregnancies, 232 women (61.4%) had their lamotrigine dose increased in the second and third trimesters and 44 women (53.7%) had their levetiracetam dose increased. Only 57 women (12.4%) had any TDM. The dose was not always decreased postpartum, and 157 women (56.9% of those who had escalated doses during pregnancy) had dose reduced following birth. Between 2012 and 2015, 29 women had an epilepsy-coded hospital discharge during pregnancy and were more likely to have had their dose of lamotrigine or levetiracetam increased. Overall, doses of lamotrigine and levetiracetam were not increased during pregnancy in 40% of the study population, dose changes were not often guided by TDM, and doses were not always reduced postpartum. PMID- 29588993 TI - Common terms for rare epilepsies: Synonyms, associated terms, and links to structured vocabularies. AB - Identifying individuals with rare epilepsy syndromes in electronic data sources is difficult, in part because of missing codes in the International Classification of Diseases (ICD) system. Our objectives were the following: (1) to describe the representation of rare epilepsies in other medical vocabularies, to identify gaps; and (2) to compile synonyms and associated terms for rare epilepsies, to facilitate text and natural language processing tools for cohort identification and population-based surveillance. We describe the representation of 33 epilepsies in 3 vocabularies: Orphanet, SNOMED-CT, and UMLS-Metathesaurus. We compiled terms via 2 surveys, correspondence with parent advocates, and review of web resources and standard vocabularies. UMLS-Metathesaurus had entries for all 33 epilepsies, Orphanet 32, and SNOMED-CT 25. The vocabularies had redundancies and missing phenotypes. Emerging epilepsies (SCN2A-, SCN8A-, KCNQ2-, SLC13A5-, and SYNGAP-related epilepsies) were underrepresented. Survey and correspondence respondents included 160 providers, 375 caregivers, and 11 advocacy group leaders. Each epilepsy syndrome had a median of 15 (range 6-28) synonyms. Nineteen had associated terms, with a median of 4 (range 1-41). We conclude that medical vocabularies should fill gaps in representation of rare epilepsies to improve their value for epilepsy research. We encourage epilepsy researchers to use this resource to develop tools to identify individuals with rare epilepsies in electronic data sources. PMID- 29588994 TI - "Saved by the Bell": Near SUDEP during intracranial EEG monitoring. AB - SUDEP is the sudden unexpected death of a person with epilepsy, when no structural or toxicological cause of death can be found. The majority of witnessed cases are reported to be preceded by a convulsive seizure and postictal hypoventilation. Here, we report an 8-year-old girl with drug-resistant focal seizures secondary to a focal cortical dysplasia type IIb. While undergoing invasive intracranial monitoring with subdural and depth electrodes, she had a clinical apnea event recorded on video, followed by bradycardia, which required resuscitation. Her intracranial electroencephalogram (EEG) during the event showed diffuse slowing and attenuation of cortical activity, with bradycardia that responded to positive pressure ventilation with oxygen. This near SUDEP event was not preceded by either an electroclinical or electrographic seizure. This is the first report of a witnessed, near-SUDEP event during intracranial monitoring. It emphasizes the fact that near-SUDEP can occur without a preceding seizure.

AB - Focal status epilepticus in POLG-related mitochondrial disease is highly refractory to pharmacological agents, including general anesthesia. We report the challenges in managing a previously healthy teenager who presented with de novo epilepsia partialis continua and metabolic stroke resulting from the homozygous p.Ala467Thr POLG mutation, the most common pathogenic variant identified in the Caucasian population. We applied transcranial direct current stimulation (tDCS; 2 mA; 20 min) daily as an adjunctive therapy because her focal seizures failed to respond to five antiepileptic drugs at maximal doses. The electrical and clinical seizures stopped after 3 days of tDCS. The second course of tDCS was administered for 14 days when the focal seizures re-emerged a month later. The patient tolerated the procedure well. Following 4 months of hospitalization and prolonged community rehabilitation, our patient has now returned to full-time education with support, and there is no report of cognitive deficit. We have demonstrated the safety and efficacy of tDCS in treating refractory focal motor seizures caused by mitochondrial disease.

AB - The epilepsy surgery database from 1984 to 2012 at the National Institutes of Health (NIH) was reviewed to determine the association of postoperative electroencephalography (EEG) with seizure recurrence. Eighty-three patients were analyzed, with 41 having at least 5 years of follow-up. The relationship between epileptiform postoperative EEG findings and seizure recurrence at 1, 2, and 5 years was not significant, despite a significant decrease in abnormal EEG recordings after surgery. Clinicians use a variety of tools to predict seizure recurrence following epilepsy surgery to guide medication management and to modulate patient expectations. EEG is but one tool for assessing the likelihood of seizure recurrence following epilepsy surgery.

AB - Ionic liquids (ILs) show brilliant performance in separating gas impurities, but few researchers have performed an in-depth exploration of the bulk and interface behavior of penetrants and ILs thoroughly. In this research, we have performed a study on both molecular dynamics (MD) simulation and quantum chemical (QC) calculation to explore the transport of acetylene and ethylene in the bulk and interface regions of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM] [BF4]). The diffusivity, solubility and permeability of gas molecules in the bulk were researched with MD simulation first. The subdiffusion behavior of gas molecules is induced by coupling between the motion of gas molecules and the ions, and the relaxation processes of the ions after the disturbance caused by gas molecules. Then, QC calculation was performed to explore the optical geometry of ions, ion pairs and complexes of ions and penetrants, and interaction potential for pairs and complexes. Finally, nonequilibrium MD simulation was performed to explore the interface structure and properties of the IL-gas system and gas molecule behavior in the interface region. The research results may be used in the design of IL separation media.

AB - The solid electrolyte interphase (SEI) of Li-ion batteries (LIBs) has been extensively studied, with most research focused on the anode, because of its significant impact on the prolonged cycle life, initial capacity loss, and safety issues. Using first-principles density functional theory (DFT) calculations and ab initio molecular dynamics (AIMD) simulations with the Hubbard correction, we examine the thermodynamic structure prediction and electrochemical stability of a spinel LiMn2O4 cathode interfaced with a carbonate electrolyte. The electronic energy levels of frontier orbitals of the electrolyte and the work function of the cathode offer clear characterization of the interfacial reactions. Our results based on both DFT calculations and AIMD simulations propose that the proton transfer mechanism at the hybrid interface is essential for initiating the SEI layer formation on the LiMn2O4 surface. Our results can be useful for identifying design concepts in the development of stable and high capacity LIBs with optimized electrodes and high-performance electrolytes.

AB - A new physiologically benign and cell membrane permeable BODIPY based molecular probe, MB-Sn, specifically senses intracellular hydrogen polysulfides (H2Sn, n > 1) localized in the endoplasmic reticulum. This reagent is suitable for mapping the intracellular distribution of H2Sn by wide-field as well as super-resolution Structured Illumination Microscopy (SIM). PMID- 29589000 TI - Osteogenic nanostructured titanium surfaces with antibacterial properties under conditions that mimic the dynamic situation in the oral cavity. AB - The study aim was to assess the impact of different surface nanofeatures on otherwise smooth titanium surfaces on bacterial adhesion as well as on their osteogenic potential. Bacterial adhesion was assessed in the presence of saliva under static and dynamic conditions to approximate both sub- and supragingival conditions in the oral cavity as the gingival seal will be affected by implantation. The ultimate goal was to develop a surface that will reduce biofilm formation but still support osseointegration in vivo. To this end nanotubular or nanopitted surfaces were created on electropolished titanium via electrochemical anodization procedures. Sandblasted/acid etched surfaces (SBAE) were used as a microrough reference. Bacterial adhesion was studied using saliva-precoated samples with S. sanguinis as a typical early colonizer of the oral cavity; osteogenic differentiation was assessed with human bone marrow stromal cells. While bacterial adhesion was reduced on all microsmooth surfaces to an average of 17% surface coverage compared to 61% on SBAE under static conditions, under dynamic conditions the nanopitted surface had a significant impact on bacterial adhesion. Here fluid flow removed all bacteria. By comparison, the reduction on the nanotubular surface was only similar to that of the SBAE reference. We hypothesise the underlying cause to be an effect of the surface morphology on the structure and composition of the saliva precoating that reduces its stability, giving rise to a self-cleaning effect. In addition, no negative influence on the osteogenic potential of the nanopitted surface could be determined by alkaline phosphatase activity, mineralization behaviour or gene expression; it remained on a par with the tissue culture plastic control. Thus, nanopitting seems to be a promising surface treatment candidate for dental implants to reduce infection related complications without compromising the implant integration. PMID- 29589005 TI - Finger-actuated microfluidic device for the blood cross-matching test. AB - A blood cross-matching test should be carried out to prevent a hemolytic transfusion reaction as the final verification step. To simplify complicated procedures of a conventional blood cross-matching test requiring bulky systems and skilled people, we present a finger-actuated microfluidic device for the blood cross-matching test. Although finger actuation is a simple action that anyone can easily accomplish, there would be a variation in the individual finger actuation that may induce the user-dependent errors of the device. Therefore, the working principle of the finger-actuated microfluidic device is newly designed to reduce the user-dependent errors by indirectly controlling the pressure of fluidic channels. The constant volume was repeatedly dispensed by pushing and releasing a pressure chamber regardless of the different pushed depths of the pressure chamber, the pushing time interval, and the end-users. The dispensed volume was linearly increased according to the number of pushing times applied to the pressure chamber and determined by adjusting the diameter of an actuation chamber. In addition, multiple fluids can be dispensed with a desirable ratio by pushing and releasing the pressure chamber. Finally, a finger-actuated microfluidic device for the blood cross-matching test was developed, which can simultaneously actuate four fluidic channels. After loading 50 MUL of whole blood samples from a donor and a recipient into two inlets of the device, the blood plasma from each individual was separated through the two plasma separation membranes. The blood cross-matching test results can be achieved by cross reacting the donor's blood plasma with the recipient's whole blood as well as the donor's whole blood with the recipient's blood plasma by pushing and releasing only a single pressure chamber within 10 min. PMID- 29589006 TI - Pretreatment with dihydroquercetin, a dietary flavonoid, protected against concanavalin A-induced immunological hepatic injury in mice and TNF-alpha/ActD induced apoptosis in HepG2 cells. AB - We have previously demonstrated the hepatoprotective effect of dihydroquercetin (DHQ) against concanavalin A (Con A)-induced immunological hepatic injury in mice. In this study, we investigated the immunoregulatory effects of DHQ on Con A induced liver injury in mice. DHQ administration significantly decreased the serum levels of alanine transaminase and aspartate transaminase, effectively prevented liver damage, and increased the survival rate of Con A-treated mice. Immunohistochemistry examination revealed that supplementation with DHQ obviously reduced infiltration of CD4+ and CD8+ T cells in the injured liver tissues. Furthermore, DHQ administration resulted in down-regulation of pro-inflammatory cytokines (TNF-alpha, IFN-gamma, IL-2, IL-4, and IL-10), the chemokine osteopontin, apoptosis factors (Fas and FasL), transcription factors that regulate Th cell differentiation (T-bet and GATA-3), perforin, granzyme B, and inducible nitric oxide synthase (iNOS). In vitro, treatment with DHQ protected HepG2 cells against TNF-alpha/ActD-induced apoptosis by inhibiting the activation of caspase-3, caspase-7, and caspase-8. In addition, DHQ reduced phosphorylation of NF-kB/p65, and inhibited the expressions of pro-apoptotic factors (p53 and Bax), while it up-regulated the expression of the anti-apoptotic factor Bcl-2. Our findings suggest that the immunosuppressive effects of DHQ ameliorated Con A mediated immunological liver injury by reducing the expression of pro inflammatory mediators and infiltration of CD4+ and CD8+ T cells in liver tissues, and DHQ protected HepG2 cells against TNF-alpha/ActD-induced apoptosis possibly via modulation of the caspase and NF-kB pathways.

AB - A new type of double uranium oxo cation [O-U-O-U-O]4+ is prepared by selective oxygen-atom abstraction from macrocyclic uranyl complexes using either boranes or silanes. A significant degree of multiple U[double bond, length as m-dash]O bonding is evident throughout the U2O3 core, but either trans-,cis- or trans ,trans-OUOUO motifs can be isolated as boron- or silicon-capped oxo complexes. Further controlled deoxygenation of the borylated system is also possible. PMID- 29589008 TI - Reactivity of bulky Ln(ii) amidinates towards P4, As4, and As4S4. AB - The reduction of P4, As4 and As4S4 (realgar) with the sterically encumbered reductants [(DippForm)2Ln(thf)2] (Ln = Sm, Yb; DippForm = {(2,6-iPr2C6H3)NC(H) = N(2,6-iPr2C6H3)}-) is reported. For the first time, purely f-element containing inverse inorganic sandwich complexes [{(DippForm)2Sm}2(MU2-eta4:eta4-E4)] (E = P, As), featuring a pi-aromatic cyclo [E4]2- middle deck, were obtained upon reaction with P4 and As4. The reaction with realgar leads to a cage disruption and the formation of the unusual species [{(DippForm)(DippForm-AsS2)}Ln(thf)]. The reactivity of divalent Ln amidinates towards main group molecules is in comparison to metallocenes faster, more efficient and thus significantly influenced by the ligand environment. Experimental results are supported by DFT calculations. PMID- 29589009 TI - Solid state p-type dye sensitized NiO-dye-TiO2 core-shell solar cells. AB - Solid state p-type dye sensitized NiO-dye-TiO2 core-shell solar cells with an organic dye PB6 were successfully fabricated for the first time. With Al2O3 as an inner barrier layer, the recombination process between injected holes in NiO and injected electrons in TiO2 was significantly suppressed and the charge transport time was also improved. PMID- 29589010 TI - Structure and nitrite reduction reactivity study of bio-inspired copper(i)-nitro complexes in steric and electronic considerations of tridentate nitrogen ligands. AB - Two copper(i)-nitro complexes [Tpm3-tBuCu(NO2)] (1) and [(Ph3P)2N][Tp3 tBuCu(NO2)] (2), containing steric bulky neutral tris(3-tert butylpyrazolyl)methane and anionic hydrotris(3-tert-butylpyrazolyl)borate ligands, have been synthesized and characterized. Complex 2 adopts a unique kappa2-binding mode of Tp3-tBu around the copper(i)-nitro environment in the solid state and shows a four-coordinated tetrahedral geometry surrounded by a nitro and three pz3-tBu groups in solution. Both complexes 1 and 2 allow for the stoichiometric reduction of NO2- to NO with H+ addition. The results of this effort show that increasing steric bulk and electron donation properties on the nitrogen ancillary ligand will improve the nitrite reduction ability of the copper(i)-nitro model complexes. PMID- 29589011 TI - Interactions of gaseous molecules with X-ray photons and photoelectrons in AP-XPS study of solid surface in gas phase. AB - Studies of the surface of a catalyst in the gas phase via photoelectron spectroscopy is an important approach to establish a correlation between the surface of a catalyst under reaction conditions or during catalysis and its corresponding catalytic performance. Unlike the well understood interactions between photoelectrons and the atomic layers of a surface in ultrahigh vacuum (UHV) and the well-developed method of quantitative analysis of a solid surface in UHV, a fundamental understanding of the interactions between X-ray photons and gaseous molecules and between photoelectrons and molecules of the gas phase in ambient pressure X-ray photoelectron spectroscopy (AP-XPS) is lacking. Through well designed experiments, here the impact of the interactions between photoelectrons and gaseous molecules and interactions between X-ray photons and gaseous molecules on the intensity of the collected photoelectrons have been explored. How the changes in photoelectron intensity resulting from these interactions influence measurement of the authentic atomic ratio of element M to A of a solid surface has been discussed herein, and methods to correct the measured nominal atomic ratio of two elements of a solid surface upon travelling through a gas phase to its authentic atomic ratio have been developed. PMID- 29589012 TI - Influence of a cobalt additive in spiro-OMeTAD on charge recombination and carrier density in perovskite solar cells investigated using impedance spectroscopy. AB - The role of additives in spiro-OMeTAD as a hole transport material (HTM) has been found to be vitally important for achieving decent photovoltaic performance of perovskite solar cells (PSCs). Four spiro-OMeTAD recipes with controlled concentrations of additives are studied in the context of PSCs. It is found that a small change in the concentration of additives results in a huge difference in the overall power conversion efficiency, which stems from the distinct charge extraction process in PSCs. Furthermore, the effect of the third additive, a cobalt complex (FK102, Co(iii)TFSI), on the carrier density and charge recombination in PSCs is extensively investigated. It is found that the presence of the cobalt additive can significantly improve the photovoltaic performance of PSCs via the suppression of charge recombination at the interface of the perovskite layer and the HTM layer, which leads to a more than doubled power conversion efficiency. PMID- 29589013 TI - Framework flexibility of ZIF-8 under liquid intrusion: discovering time-dependent mechanical response and structural relaxation. AB - The structural flexibility of a topical zeolitic imidazolate framework with sodalite topology, termed ZIF-8, has been elucidated through liquid intrusion under moderate pressures (i.e. tens of MPa). By tracking the evolution of water intrusion pressure under cyclic conditions, we interrogate the role of the gate opening mechanism controlling the size variation of the pore channels of ZIF-8. Interestingly, we demonstrate that its channel deformation is recoverable through structural relaxation over time, hence revealing the viscoelastic mechanical response in ZIF-8. We propose a simple approach employing a glycerol-water solution mixture, which can significantly enhance the sensitivity of intrusion pressure for the detection of structural deformation in ZIF-8. By leveraging the time-dependent gate-opening phenomenon in ZIF-8, we achieved a notable improvement (50%) in energy dissipation during multicycle mechanical deformation experiments.

AB - Trianglimine, a chiral triangular-shaped hexaimine, exists in at least three apohost polymorphic forms. Form I had been previously obtained by crystallisation from a mixture of dichloromethane and acetonitrile and we have now crystallised Form II from acetone. Both forms possess similar packing arrangements, but Form II undergoes a reversible phase transition to Form III, as well as colossal anisotropic positive thermal expansion. Form I does not exhibit any remarkable thermal properties. PMID- 29589015 TI - Fabrication of a hierarchical NiO/C hollow sphere composite and its enhanced supercapacitor performance. AB - A hierarchical NiO/C hollow sphere composite (NiO/C-HS) was prepared via semi sacrificial template-assisted hydrothermal and calcination methods. NiO/C-HS, with well-dispersed NiO nanosheets supported by carbon hollow spheres, exhibited excellent electrochemical performance. The method was heuristic for the design of other composites and suitable for ameliorating the poor stability of transition metal oxides. PMID- 29589016 TI - On-surface synthesis of polyethylenedioxythiophene. AB - On-surface synthesis of conjugated polymers is made challenging by the need to promote the desired reaction while preventing or minimizing unwanted ancillary reactions that compromise the product integrity. We perform a comprehensive study of the reactions of 2,5-dichloro-3,4-ethylenedioxythiophene on coinage metal surfaces, and demonstrate that only on Ag(111) can we obtain a planar polymer product, polyethylenedioxythiophene (PEDOT). PMID- 29589017 TI - One-pot production of porous assemblies by PISA of star architecture copolymers: a simulation study. AB - The polymerization-induced self-assembly (PISA) process of star architecture copolymers is studied by dissipative particle dynamics and a reaction model. According to the simulation results, the porous vesicles can be produced directly by PISA of these copolymers. Average pore size and distribution of pore size can be influenced by alphaAS (the solubility between solvophilic blocks and solvent) and alphaAB (the solubility between solvophilic blocks and solvophobic blocks), while different self-assembly progress can be observed at different alphaAS and alphaAB. In addition, the star architecture can promote the formation of porous vesicles compared with linear copolymers. The steric effect of two solvophobic chains is verified as the key factor in formation of the porous vesicles. Further enhancement of such an effect can widen the range of alphaAS for production of porous vesicles, accompanied by a shrinkage of the range of alphaAB and a large reduction of pore size distribution. This work provides deeper understanding of the PISA of star architecture copolymers and is instructive in the experimental production of porous nano-materials. PMID- 29589018 TI - Regulating the local pH level of titanium via Mg-Fe layered double hydroxides films for enhanced osteogenesis. AB - Hard tissue implant materials which can cause a suitable alkaline microenvironment are thought to be beneficial for stimulating osteoblast differentiation while suppressing osteoclast generation. To make the local pH around the interface between materials and cells controllable, we prepared a series of Mg-Fe layered double hydroxide (LDH) films on acid-etched pure titanium surfaces via hydrothermal treatment. By adjusting the Mg/Fe proportion ratio, the interlayer spacing of Mg-Fe LDHs was regulated, making their OH- exchange abilities adjustable, and this ultimately resulted in a microenvironment with a controllable pH value. In vitro experiments demonstrated that the Mg-Fe LDH film modified titanium surface possessed good biocompatibility and osteogenic activity, especially the Mg-Fe LDH film with Mg/Fe proportion ratio of 4, which could form a suitable alkaline microenvironment for the growth and osteogenetic differentiation of stem cells. These results demonstrate the potential application of the prepared Mg-Fe LDH films in enhancing the osteogenesis of implant materials while providing a new way into the design of controllable alkaline environment. PMID- 29589019 TI - Synthesis, properties, and formation mechanism of Mn-doped Zn2SiO4 nanowires and associated heterostructures. AB - In this work, we have put forth a facile hydrothermal approach to synthesize an array of one-dimensional (1D) Mn-doped Zn2SiO4 nanostructures. Specifically, we have probed and correlated the effects of controllable reaction parameters such as the pH and Mn dopant concentrations with the resulting crystal structures and morphologies of the products obtained. Based upon our results, we find that careful tuning of the pH versus the Mn dopant level gives rise to opposite trends with respect to the overall size of the resulting one-dimensional nanostructures. Significantly, we have highlighted the role of the Mn dopant ion concentration as a potentially generalizable reaction parameter in solution-based synthesis for controlling morphology and hence, the observed optical behavior. Indeed, such a strategy can be potentially generalized to systems such as but not limited to Mn doped ZnS, CdS, and CdSe quantum dots (QD), which, to the best of our knowledge, denote promising candidates for a variety of optoelectronic applications. Specifically, we have carefully optimized the synthesis conditions in order to generate a series of chemically well-defined Mn-doped Zn2SiO4 not only possessing Mn concentrations ranging from 3% to 8% but also characterized by highly crystalline, monodisperse wire-like motifs measuring ~30 nm in diameter and ~700 nm in length. Optically, the photoluminescence signals associated with the 1D series yielded a volcano-shaped relationship between PL intensities and the Mn dopant level. In additional experiments, we have immobilized CdSe quantum dots (QDs) onto the external surfaces of our as-synthesized Mn-doped Zn2SiO4 nanowires, in order to form novel composite heterostructures. The optical properties of the CdSe QD-Mn:Zn2SiO4 heterostructures have been subsequently examined. Our results have demonstrated the likely co-existence of both energy transfer and charge transfer phenomena between the two constituent components of our as-prepared composites. Specifically, when both components are photoexcited, both energy transfer and charge transfer were found to plausibly occur, albeit in opposite directions. When the CdSe QDs are excited alone for example, charge transfer probably takes place from the CdSe QDs to the dopant Mn2+ ions. We believe that our as-processed heterostructures are therefore promising as a tunable light-harvesting motif. Essentially, these materials have broadened the effective light absorption range for optical 'accessibility', not only through their incorporation of dopant-tunable Zn2SiO4 possessing complementary absorption properties to those of the QDs but also through their integration of CdSe QDs with size-tailorable optical behavior. PMID- 29589020 TI - Core-shell structured MnSiO3 supported with CNTs as a high capacity anode for lithium-ion batteries. AB - Metal silicates are good candidates for use in lithium ion batteries (LIBs), however, their electrochemical performance is hindered by their poor electrical conductivity and volume expansion during Li+ insertion/desertion. In this work, one-dimensional core-shell structured MnSiO3 supported with carbon nanotubes (CNTs) (referred to as CNT@MnSiO3) with good conductivity and electrochemical performance has been successfully synthesized using a solvothermal process under moderate conditions. In contrast to traditional composites of CNTs and nanoparticles, the CNT@MnSiO3 composite in this work is made up of CNTs with a layer of MnSiO3 on the surface. The one-dimensional CNT@MnSiO3 nanotubes provide a useful channel for transferring Li+ ions during the discharge/charge process, which accelerates the Li+ diffusion speed. The CNTs inside the structure not only enhance the conductivity of the composite, but also prevent volume expansion. A high reversible capacity (920 mA h g-1 at 500 mA g-1 over 650 cycles) and good rate performance were obtained for CNT@MnSiO3, showing that this strategy of synthesizing coaxial CNT@MnSiO3 nanotubes offers a promising method for preparing other silicates for LIBs or other applications. PMID- 29589021 TI - Structural coloration of transmission light through self-aligned and complementary plasmonic nanostructures. AB - Structural coloration of natural surfaces often originates from the change of reflected colors depending on the viewing or illumination angle. Recently, the structural coloration of nanoplasmonic structures has attracted a great deal of attention due to high compactness, robust stability and high color-tunability, as well as high sensitivity to the incidence angle. Here we report complementary plasmonic structures (CPS) for transmission structural coloration by tailoring a single spectral peak depending on the incidence angle of light. The CPS features self-aligned silver nanohole and nanodisk arrays, supported by dielectric nanopillar arrays of hydrogen silsesquioxane. Unlike the conventional hybridized nanostructures of plasmonic nanohole and nanodisk arrays, the nanodisks of CPS effectively attenuate undesired spectral peaks of nanoholes by exploiting an extinction peak of nanodisks, serving as a spectral suppressor. As a result, a single transmission spectral peak becomes red-shifted from 736 nm to 843 nm as the incidence angle varies from 0 degrees to 30 degrees . This unique configuration provides a new direction for tunable filters that can be utilized for compact multispectral or hyperspectral imaging applications. PMID- 29589022 TI - Optimizing the motion of a folding molecular motor in soft matter. AB - We use molecular dynamics simulations to investigate the displacement of a periodically folding molecular motor in a viscous environment. Our aim is to find significant parameters to optimize the displacement of the motor. We find that the choice of a massy host or of small host molecules significantly increase the motor displacements. While in the same environment, the motor moves with hopping solid-like motions while the host moves with diffusive liquid-like motions, a result that originates from the motor's larger size. Due to hopping motions, there are thresholds on the force necessary for the motor to reach stable positions in the medium. These force thresholds result in a threshold in the size of the motor to induce a significant displacement, that is followed by plateaus in the motor displacement.

AB - On the road towards quantum devices, chemistry can offer elementary pieces with a built-in function, like [TbPc2]- which functions as a molecular transistor for nuclear spin detection. We argue that a large class of molecules have similar potential. In particular, we review the recent progress regarding highly coherent spin qubits based on vanadium dithiolate complexes. We propose their use as single molecule transistors to read and control a triple nuclear spin qubit, which could enable a low-current nuclear spin detection scheme by means of a spin valve effect.

AB - A novel, versatile and modular route to unsymmetrical diborane(4) derivatives bearing either two different diol moieties or one diol and one diamine moiety is presented. Utilising the very basic approach of reacting a boron nucleophile with a boron electrophile to establish the B-B bond allows a simple variation of the two individual boron moieties. The copper(i) boryl complexes used as nucleophilic boron sources are readily accessible from commercially available symmetrical diborane(4) derivatives, whilst equally readily available boron halide derivatives are used as electrophiles. Seven previously inaccessible diborane(4) derivatives were obtained and fully characterised, including single crystal X-ray structure determinations, illustrating the broad scope of the method.

AB - The wide application of superhydrophobic membranes has been limited due to their complicated preparation technology and weak durability. Inspired by the mechanical flexibility of nanofibrous biomaterials, nanofibrils have been successfully generated from Kevlar, which is one of the strongest synthetic fibers, by appropriate hydrothermal treatment. In this study, a robust superhydrophobic PDMS/PVDF@KNFs membrane is prepared via a simple one-step process and subsequent curing without combination with inorganic fillers. The as prepared PDMS/PVDF@KNFs membrane not only shows efficient oil/water separation ability and oil absorption capacity but also has excellent superhydrophobicity stability after deformation. The resultant membrane shows stretchability, flexibility and flame retardance because of the reinforcing effect and the excellent flame retardancy of Kevlar. We believe that this simple fabrication of PDMS/PVDF@KNFs has promising applications in filtering membranes and wearable devices.

AB - Three novel single-chain bis(phosphocholines) bearing two lateral alkyl chains of variable length next to the headgroup have been synthesized as model lipids for naturally occurring archaeal membrane lipids. The synthesis was realized using the Cu-catalyzed Grignard bis-coupling reaction of a primary bromide as a side part and a 1,omega-dibromide as a centre part. We could show that the aggregation behaviour of the resulting bolalipids strongly depends on the length of the lateral alkyl chain: the C3-branched bolalipid self-assembles into lamellar sheets, whereas the C6- and C9-analogues form nanofibres. The lamella-forming bolalipids could be used in the future to prepare stable and tailored liposomes for oral drug delivery. PMID- 29589029 TI - Molecular dynamics study of the LCST transition in aqueous poly(N-n propylacrylamide). AB - The breadth of technological applications of smart polymers relies on the possibility of tuning their molecular structure to respond to external stimuli. In this context, N-substituted acrylamide-based polymers are widely studied thermoresponsive polymers. Poly(N-n-propylacrylamide) (PNnPAm), which is a structural isomer of the poly(N-isopropylacrylamide) (PNIPAm) exhibits however, a lower phase transition in aqueous solution. In this work, we use all-atom molecular dynamics simulations of PNnPAm in aqueous solutions to study, from a microscopic point-of-view, the influence of chain size and concentration on the LCST of PNnPAm. Our analysis shows that the collapse of a single oligomer of PNnPAm upon heating is dependent on the chain length and corresponds to a complex interplay between hydration and intermolecular interactions. Analysis of systems with multiple chains shows an aggregation of PNnPAm chains above the LCST. PMID- 29589032 TI - Enhanced solar water-splitting activity of novel nanostructured Fe2TiO5 photoanode by electrospray and surface F-modification. AB - Fe2TiO5 is recognized as a novel photoanode material for solar water splitting. However, it has been seldom studied as a photoelectrode by itself, and its practical performance still needs to be improved. Herein, nanostructured Fe2TiO5 photoanode is prepared by the electrospray technique. The effects of the synthesis parameters on the photoelectrochemical water splitting activity are studied including the substrate temperature and film thickness. In addition, surface F-modification is applied on pure Fe2TiO5 to further improve its photoelectrochemical performance. Also, the water splitting photocurrent of F treated Fe2TiO5 increases to 0.4 mA cm-2 at 1.23 VRHE, which is higher than that of pristine Fe2TiO5. X-ray photoelectron spectroscopy confirms the formation of surface Ti-F bonds after surface F-treatment, which facilitates the transfer of holes and the breakage of O-H bond under illumination. The enhanced performance can be attributed to a synergetic effect of nanoarchitecture and surface F modification. Therefore, the nanoarchitecture assisted by surface F-modification offers an effective strategy to prepare high-efficiency nanostructured complex metal oxides for solar water splitting.

PMID- 29589034 TI - Melatonin-directed micellization: a case for tryptophan metabolites and their classical bioisosteres as templates for the self-assembly of bipyridinium-based supramolecular amphiphiles in water. AB - The bulk solution properties of amphiphilic formulations are derivative of their self-assembly into higher ordered supramolecular assemblies known as micelles and of their ordering at the air-water interface. Exerting control over the surface active properties of amphiphiles and their propensity to aggregate in pure water is most often fine-tuned by covalent modification of their molecular structure. Nevertheless structural constraints which limit the performance of amphiphiles do emerge when trying to develop more sophisticated systems which undergo for example, shape-defined controlled assembly and/or respond to external stimuli. In this regard, the template-modulated assembly of the so-called "supramolecular amphiphiles" continues to make progress ordering molecules that otherwise have very little to no driving force to aggregate in a prescribed manner in aqueous solutions. Herein we describe the template-modulated micellization and ordering at the air-water interface of bipyridinium-based supramolecular amphiphiles triggered by host-guest interactions with high specificity for the neurotransmitter melatonin over its biosynthetic synthon l-tryptophan and the thermodynamic parameters governing the template-modulated micellization process. When bound to the bipyridinium units of micellized surfactant molecules, melatonin effectively serves as "molecular glue" capable of lowering the CMC by 52% as compared to untemplated solutions. Analysis of this system suggests that a hallmark of donor-acceptor template-modulated micellization in water is a strong positively correlated temperature dependence of the CMC and the absence of a U shaped CMC-temperature curve. Our findings make a case for the incorporation of l tryptophan-based metabolites and their classical synthetic pharmaceutical bioisosteres as potential targets/components of donor-acceptor CT-based supramolecular amphiphile systems/materials operating in water.

AB - The structure and atomic ordering of Au-Ag nanoparticles grown in the gas phase are determined by a combination of HAADF-STEM, XPS and Refl-XAFS techniques as a function of composition. It is shown consistently from all the techniques that an inversion of chemical ordering takes place by going from Au-rich to Ag-rich compositions, with the minority element always occupying the nanoparticle core, and the majority element enriching the shell. With the aid of DFT calculations, this composition-tunable chemical arrangement is rationalized in terms of a four step growth process in which the very first stage of cluster nucleation plays a crucial role. The four-step growth mechanism is based on mechanisms of a general character, likely to be applicable to a variety of binary systems besides Au-Ag.

AB - Hierarchical nanosheet-based Bi2MoO6 microboxes are synthesized by a facile template-assisted strategy. MnCO3 microcubes are prepared as templates for the growth of Bi2MoO6 nanosheets and then etched by using HCl aqueous solution. In particular, the hierarchical Bi2MoO6 microboxes provide a large surface area, and facilitate visible-light absorption and charge separation, demonstrating efficient photocatalytic performance. This work highlights a new method to prepare hollow nanosheet-built Bi2MoO6 structures with high photocatalytic properties.

AB - The gold(i)-catalyzed oxycyclization of beta-aryl monosubstituted o (alkynyl)styrenes gives rise to 1-alpha-methoxy or 1-alpha-hydroxybenzyl-1H indenes in a diastereospecific way. In contrast to beta,beta-disubstituted o (alkynyl)styrenes, the stereochemical outcome of this process, diastereospecific reaction supports the higher contribution of a gold intermediate with a cyclopropylcarbene-like character.

PMID- 29589039 TI - Blunt traumatic injury during pregnancy: a descriptive analysis from a level 1 trauma center. AB - PURPOSE: The precise incidence of trauma in pregnancy is not well-known, but trauma is estimated to complicate nearly 1 in 12 pregnancies and it is the leading non-obstetrical cause of maternal death. METHODS: A retrospective study of all pregnant women presented to national level 1 trauma center from July 2013 to June 2015 was conducted. Descriptive and inferential statistics applied for data analysis. RESULTS: Across the study period, a total of 95 pregnant women were presented to the trauma center. The average incidence rate of traumatic injuries was 250 per 1000 women of childbearing age presented to the Hamad Trauma Center. The mean age of patients was 30.4 +/- SD 5.6 years, with age ranging from 20 to 42 years. The mean gestational age at the time of injury was 24.7 +/- 8.7 weeks which ranged from 5 to 37 weeks. The majority (47.7%) was in the third trimester of the pregnancy. In addition, the large majority of injuries was due to MVCs (74.7%) followed by falls (15.8%). CONCLUSIONS: Trauma during pregnancy is not an uncommon event particularly in the traffic-related crashes. As it is a complex condition for trauma surgeons and obstetrician, an appropriate management protocol and multidisciplinary team are needed to improve the outcome and save lives of both the mother and fetus. PMID- 29589040 TI - [Global and national strategies against antibiotic resistance]. AB - Antimicrobial resistance (AMR) is increasingly perceived as a global health problem. To tackle AMR effectively, a multisectoral one health approach is needed. We present some of the initiatives and activities at the national and global level that target the AMR challenge. The Global Action Plan on AMR, which has been developed by the World Health Organization (WHO), in close collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE) is considered a blueprint to combat AMR. Member states endorsed the action plan during the World Health Assembly 2015 and committed themselves to develop national action plans on AMR. The German Antibiotic Resistance Strategy (DART 2020) is based on the main objectives of the global action plan and was revised and published in 2015. Several examples of the implementation of DART 2020 are outlined here. PMID- 29589042 TI - [Hemostyptics for treatment of junctional vascular injuries : Management of traumatic vascular injuries at the transition from trunk to extremities]. AB - BACKGROUND: Uncontrolled post-traumatic bleeding is still the leading cause of death among trauma patients. In situations of mass casualty incidents (MASCAL) and military conflicts the treatment of uncontrolled critical bleeding is a challenge and associated with a worse outcome due to the austere environment; however, even under optimal treatment circumstances in situations of individual medicine the severity of vascular trauma is underestimated. As a consequence, this leads to a poorer prognosis for patients with (vascular) injuries. From this perspective it was reasonable to intensify the training of physicians, paramedics (Advanced Trauma Life Support(c)) and first responders (Hartford consensus) for handling of critical bleeding in traumatized patients. Furthermore, the main emphasis of the revised S3 clinical guidelines on polytrauma/severely injured treatment from 2016 of the German Society for Trauma Surgery is on the preclinical treatment. Despite a renaissance and increasing use of tourniquets, the treatment of bleeding in the transition from the trunk to the extremities (junctional vascular injuries), which are inaccessible to placing a tourniquet, remains a problem. CONCLUSION: It was the military that in addition to the development of special tourniquets, intensified research programs and the implementation of hemostatic devices and dressings in this anatomical region. This article deals with junctional vascular injuries at the transition between the trunk and the extremities. In addition to the anatomical situation, this article gives the reader an overview of the currently available hemostyptics and their mode of action. PMID- 29589041 TI - Genome-wide association mapping for resistance to leaf rust, stripe rust and tan spot in wheat reveals potential candidate genes. AB - KEY MESSAGE: Genome-wide association mapping in conjunction with population sequencing map and Ensembl plants was used to identify markers/candidate genes linked to leaf rust, stripe rust and tan spot resistance in wheat. Leaf rust (LR), stripe rust (YR) and tan spot (TS) are some of the important foliar diseases in wheat (Triticum aestivum L.). To identify candidate resistance genes for these diseases in CIMMYT's (International Maize and Wheat Improvement Center) International bread wheat screening nurseries, we used genome-wide association studies (GWAS) in conjunction with information from the population sequencing map and Ensembl plants. Wheat entries were genotyped using genotyping-by-sequencing and phenotyped in replicated trials. Using a mixed linear model, we observed that seedling resistance to LR was associated with 12 markers on chromosomes 1DS, 2AS, 2BL, 3B, 4AL, 6AS and 6AL, and seedling resistance to TS was associated with 14 markers on chromosomes 1AS, 2AL, 2BL, 3AS, 3AL, 3B, 6AS and 6AL. Seedling and adult plant resistance (APR) to YR were associated with several markers at the distal end of chromosome 2AS. In addition, YR APR was also associated with markers on chromosomes 2DL, 3B and 7DS. The potential candidate genes for these diseases included several resistance genes, receptor-like serine/threonine protein kinases and defense-related enzymes. However, extensive LD in wheat that decays at about 5 * 107 bps, poses a huge challenge for delineating candidate gene intervals and candidates should be further mapped, functionally characterized and validated. We also explored a segment on chromosome 2AS associated with multiple disease resistance and identified seventeen disease resistance linked genes. We conclude that identifying candidate genes linked to significant markers in GWAS is feasible in wheat, thus creating opportunities for accelerating molecular breeding. PMID- 29589043 TI - [Tinea capitis and onychomycosis due to Trichophyton soudanense : Successful treatment with fluconazole-literature review]. AB - Two African girls who moved to Germany only 4 weeks ago presented to the dermatological office with itchy and scaling skin lesions of the scalp and the thighs. The entire scalp of both girls was affected by a white, dry dandruff and a squamous crust. Dry centrifugal spreading erythematosquamous lesions were found on the thighs. The surface of the left thumbnail of the younger girl was whitish. The Blancophor(r) preparations which were performed under the suspicion of a tinea capitis et corporis and onychomycosis from skin scrapings of the scalp and the thighs, and from the thumbnail of the younger child were positive. Cultivation of three samples from the affected body sites-hair, skin and nail revealed Trichophyton (T.) soudanense. For confirmation of the species identification, the isolates were subject of sequencing of ITS region of the rDNA and also of the translation elongation factor 1 alpha (TEF 1 alpha) gene. The phylogenetic analysis of the strains-the dendrogram of fungal strains demonstrated the genetic differences between T. soudanense and T. rubrum. In contrast, sequencing of the TEF 1 alpha gene did not allow any discrimination between T. soudanense and T. rubrum. Both girls were treated orally with fluconazole. For topical treatment of both girls, ciclopirox olamine solution and terbinafine cream were administered, each once daily. After 8 weeks oral fluconazole therapy the dermatomycoses of skin, scalp, and thumbnail of both children were completely healed. Currently, in Germany and Europe, in immigrants from West African countries (e. g., from Angola) dermatophytoses due to T. soudanense have to be expected. Cultural identification of the pathogen is relatively simple. However, only molecular methods allow the exact discrimination of T. violaceum and T. rubrum. PMID- 29589045 TI - Polycyclic Aromatic Hydrocarbons in Urban Soil in the Semi-arid City of Xi'an, Northwest China: Composition, Distribution, Sources, and Relationships with Soil Properties. AB - Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment. This study collected a total of 62 urban soil samples from the typical semi-arid city of Xi'an in Northwest. They were analyzed for the composition, distribution, and sources of PAHs as well as the relationships with soil properties. The sum of 16 individual PAHs (?16PAHs) ranged from 390.6 to 10,652.8 MUg/kg with a mean of 2052.6 MUg/kg. The average ?16PAHs decreased in the order of the third ring road (2321.1 MUg/kg) > the first ring road (1893.7 MUg/kg) > the second ring road (1610.0 MUg/kg), and in the order of industrial areas (3125.6 MUg/kg) > traffic areas (2551.6 MUg/kg) > educational areas (2414.4 MUg/kg) > parks (1649.5 MUg/kg) > mixed commercial and traffic areas (1332.8 MUg/kg) > residential areas (1031.0 MUg/kg). The most abundant PAHs in the urban soil were 3- to 5-ring PAHs. Elevated levels of PAHs were found in industrial and traffic areas from the east and west suburbs and the northwest corner of Xi'an as well as the northeast corner in the urban district of Xi'an. PAHs in the urban soil were mainly related to the combustion of fossil fuel (i.e., coal, gasoline, diesel, and natural gas) and biomass (i.e., grass and wood) (variance contribution 57.2%) as well as the emissions of petroleum and its products (variance contribution 29.9%). Soil texture and magnetic susceptibility were the main factors affecting the concentration of PAHs in urban soil. Meanwhile, this study suggested that the single, rapid, and nondeductive magnetic measurements can be an indicator of soil pollution by PAHs. PMID- 29589044 TI - [The role of innate immunity in otitis media]. AB - Otitis media (OM) belongs to the most common pediatric diseases and causes more medical contacts, surgical interventions, and drug prescriptions than any other infectious disease. Recent findings have identified a critical role of innate immunity in recovery from OM. The middle ear mucosa identifies invading pathogens by sensing pathogen-associated molecule patterns (PAMPs) via pattern recognition receptors such as the Toll-like receptors (TLRs). They generate immediate antimicrobial responses and cytokine release, leading to an inflammatory reaction as seen in acute or chronic OM. Cross-talk between TLRs can enhance or suppress the healing process in the middle ear. In order to prevent over-activation on the one hand and insufficient immune response on the other, the signaling network between different TLRs must be integrated and controlled by positive and negative feedback loops. This guarantees a proper immune response in the middle ear after infection. In this review, we focus on the involvement of the innate immune system and TLRs in OM, as well on their relevance for new vaccination strategies and immunotherapies. PMID- 29589046 TI - [Surgical therapy of ischiofemoral impingement by lateralizing intertrochanteric osteotomy]. AB - OBJECTIVE: Lateralizing, derotating intertrochanteric varus osteotomy to increase the ischiofemoral space to counter painful impingement of the lesser trochanter and the os ischium with resulting entrapment of quadratus femoris muscle. INDICATIONS: Symptomatic ischiofemoral impingement (IFI) caused by Coxa valga et antetorta, Coxa valga or Coxa antetorta, or a short femoral neck. CONTRAINDICATIONS: Anatomic configuration suggestive of IFI in asymptomatic patients. Symptomatic IFI caused by another underlying pathology. Valgus deformity of the knee. SURGICAL TECHNIQUE: Measurement of femoral antetorsion. Planning of the osteotomy, lateralization, varus angle for correction, rotation and offset correction, leg length change, and osteosynthesis plate. General or spinal anesthesia in supine or lateral position. Skin incision (15 cm) beginning lateral of the greater trochanter tip, distally along the axis of the femur. Preparation onto the femur by L-shaped dissection of the vastus lateralis from the bone. A Kirschner(K-)wire is then positioned along the anterior femoral neck to designate the femoral neck antetorsion. A triangle set on the lateral femoral cortexis is used to determine the osteotomy angle. In the thus determined angle, a second K-wire is shot centrally along the femoral neck axis just inferior to its cranial cortex. About 5 mm distal to the second wire, the entry for the blade is prepared using a drill. Using the blade setting instrument, the blade is introduced into the femoral neck, then slightly pulled back. The rotation is then marked on the anterior femoral cortex proximal and distal to the planned osteotomy and the osteotomy is performed. A blade plate without displacement is impacted. The osteotomy is then reduced, the distal fragment pulled laterally onto the plate, and the screws inserted after compression of the osteotomy with a tension device. POSTOPERATIVE MANAGEMENT: Touch-toe bearing for 6 weeks, then radiological assessment of osteotomy healing before an increase in weight bearing (15 kg/week). Hip flexion limited to 90 degrees for 6 weeks. Elective implant removal after 12-18 months. RESULTS: Studies of this lateralizing varus osteotomy have not been published. The 25-year results of the conventional derotating intertrochanteric varus osteotomy technique show good functional results and low complication rates, with non-union being the most common. Arthroscopic resection of the lesser trochanter has been reported as a surgical alternative in the treatment of IFI in case reports and small series. Advantages of the osteotomy are the restoration of biomechanics and preservation of iliopsoas tendon insertion.

AB - An 81-year-old woman with infarct-related cardiogenic shock was admitted to the cardiac catheterization laboratory. Coronary angiography revealed an occlusion of the ramus interventricularis anterior. Due to incomplete flow after the percutaneous coronary intervention with implantation of three coronary stents and high thrombus burden, tirofiban was given as a bail out therapy. A central venous catheter (CVC) aimed at the internal jugular vein was incidentally inserted in the common carotid artery, resulting in acute dyspnea and a hemorrhagic shock due to a massive cervical hematoma. Although the CVC is a frequently used intervention in critical care, the procedure still carries some risks of iatrogenic injury. Knowledge about the emergency management of CVC-associated complications is therefore essential. PMID- 29589048 TI - Efficiency of C3 and C4 Plant Derived-Biochar for Cd Mobility, Nutrient Cycling and Microbial Biomass in Contaminated Soil. AB - Biochar is considered a novel soil amendment to reduce metal mobility, but its influence on soil chemical and biochemical properties is not fully understood. In the present study, biochar derived from rice straw (RSB), rice hull (RHB), and maize stover (MSB) was used to evaluate comparative efficiency on Cd mobility and soil biochemical properties. Ammonium nitrate extractable Cd significantly decreased among all the applied biochar types and application rates. The European Community Bureau of Reference (BCR) technique showed significant decrease in acid soluble Cd by 24%-32%, 19%-23%, and 22%-27% for RSB, RHB, and MSB, respectively at the 1.5% and 3% rate. However, the concentration of Cd in the residual increased by 38%, 35% and 36% for RSB, RHB and MSB, respectively at a 3% application rate. Soil microbial biomass (C and N) and inorganic nitrogen forms (NH4 and NO3) significantly increased among all biochar applications. Overall, RSB demonstrated positive results as soil amendments for Cd immobilization, increasing soil nutrient availability, and enhancing soil microbial biomass. PMID- 29589049 TI - Inferior outcome of revision of unicompartmental knee arthroplasty to total knee arthroplasty compared with primary total knee arthroplasty: systematic review and meta-analysis. AB - PURPOSE: The purpose of this study was to compare the revision of unicompartmental knee arthroplasty (UKA) to total knee arthroplasty (TKA) with primary TKA through a review of previously published studies. The hypothesis was that the revised UKA group would need additional operative procedures, including the use of stems and augments, resulting in poorer clinical outcomes than those of the primary TKA group. METHODS: A literature search of online register databases was performed to identify clinical trials that compared revised UKA to TKA with primary TKA. An electronic literature search was performed using the Medline, Embase, Cochrane Library, Web of Science, and Scopus databases. No language or date restrictions were applied. RESULTS: A total of 2034 articles were identified from a keyword search, of which 11 studies were determined as eligible. They were all retrospective comparative studies. The revised UKA to TKA group had longer operation times resulting from additional procedures such as bone grafting and use of stems and augments, higher reoperation rates, and worse postoperative clinical outcomes based on the Western Ontario and McMaster Universities Osteoarthritis Index and Oxford Knee Score than the primary TKA group, with the differences being statistically significant. CONCLUSION: UKA should not be considered an alternative procedure to TKA. LEVEL OF EVIDENCE: Therapeutic Level III. PMID- 29589050 TI - Improved early outcome after TKA through an app-based active muscle training programme-a randomized-controlled trial. AB - PURPOSE: The purpose of this prospective randomized-controlled trial (RCT) was to evaluate if an app-based feedback-controlled active muscle training programme can be used to improve the outcome in the immediate postoperative period after total knee arthroplasty (TKA). METHODS: Sixty patients, with a median age of 65.9 years (range 45-84), awaiting primary TKA were randomized into a control and training group. Both groups followed an identical postoperative protocol. In addition, the training group postoperatively performed an app-based feedback-controlled active muscle training programme multiple times daily. Outcome measures were active and passive range of motion (ROM), pain at rest and in motion, knee extension strength, the timed "Up and Go", 10-m Walk Test, 30-s Chair Stand Test, Knee Injury and Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS), and clinical data. RESULTS: The training group performed an average of 18.4 training sessions, which led to significantly higher ROM, less pain at rest and in motion, higher strength, and significantly higher functional scores. More training correlated with a better outcome. CONCLUSIONS: The use of an app-based feedback controlled active muscle training programme can improve the clinical outcome after TKA, especially ROM and reduce pain. Clinically relevant is that the training programme could be considered an alternative to continuous passive motion after total knee arthroplasty. LEVEL OF EVIDENCE: II.

AB - The chemotherapy-induced nausea and vomiting (CINV) is one of the most frequent side effects in cytostatic therapy and a profound challenge during the therapy of cancer patients. Therefore, standardized guideline-orientated prophylaxis is essential and a fundamental contribution for the success of treatment. This review summarizes the current recommendations for CINV of the Multinational Association of Supportive Care in Cancer (MASCC) and European Society of Medical Oncology (ESMO), the American Society for Clinical Oncology (ASCO), the National Comprehensive Cancer Network (NCCN) and the S3-guideline Supportive Therapie of the Leitlinienprogramm Onkologie and shall facilitate its use in the daily routine. PMID- 29589052 TI - The nitrone spin trap 5,5-dimethyl-1-pyrroline N-oxide dampens lipopolysaccharide induced transcriptomic changes in macrophages. AB - OBJECTIVE: M1-like inflammatory phenotype of macrophages plays a critical role in tissue damage in chronic inflammatory diseases. Previously, we found that the nitrone spin trap 5,5-dimethyl-1-pyrroline N-oxide (DMPO) dampens lipopolysaccharide (LPS)-triggered inflammatory priming of RAW 264.7 cells. Herein, we tested whether DMPO by itself can induce changes in macrophage transcriptome, and that these effects may prevent LPS-induced activation of macrophages. MATERIALS AND METHODS: To test our hypothesis, we performed a transcriptomic and bioinformatics analysis in RAW 264.7 cells incubated with or without LPS, in the presence or in the absence of DMPO. RESULTS: Functional data analysis showed 79 differentially expressed genes (DEGs) when comparing DMPO vs Control. We used DAVID databases for identifying enriched gene ontology terms and Ingenuity Pathway Analysis for functional analysis. Our data showed that DMPO vs Control comparison of DEGs is related to downregulation immune-system processes among others. Functional analysis indicated that interferon-response factor 7 and toll-like receptor were related (predicted inhibitions) to the observed transcriptomic effects of DMPO. Functional data analyses of the DMPO + LPS vs LPS DEGs were consistent with DMPO-dampening LPS-induced inflammatory transcriptomic profile in RAW 264.7. These changes were confirmed using Nanostring technology. CONCLUSIONS: Taking together our data, surprisingly, indicate that DMPO by itself affects gene expression related to regulation of immune system and that DMPO dampens LPS-triggered MyD88- and TRIF-dependent signaling pathways. Our research provides critical data for further studies on the possible use of DMPO as a structural platform for the design of novel mechanism-based anti-inflammatory drugs. PMID- 29589053 TI - Loss of Wilms tumor 1 protein is a marker for apoptosis in response to replicative stress in leukemic cells. AB - A remaining expression of the transcription factor Wilms tumor 1 (WT1) after cytotoxic chemotherapy indicates remaining leukemic clones in patients. We determined the regulation and relevance of WT1 in leukemic cells exposed to replicative stress and DNA damage. To induce these conditions, we used the clinically relevant chemotherapeutics hydroxyurea and doxorubicin. We additionally treated cells with the pro-apoptotic kinase inhibitor staurosporine. Our data show that these agents promote apoptosis to a variable extent in a panel of 12 leukemic cell lines and that caspases cleave WT1 during apoptosis. A chemical inhibition of caspases as well as an overexpression of mitochondrial, anti-apoptotic BCL2 family proteins significantly reduces the processing of WT1 and cell death in hydroxyurea-sensitive acute promyelocytic leukemia cells. Although the reduction of WT1 correlates with the pharmacological efficiency of chemotherapeutics in various leukemic cells, the elimination of WT1 by different strategies of RNA interference (RNAi) does not lead to changes in the cell cycle of chronic myeloid leukemia K562 cells. RNAi against WT1 does also not increase the extent of apoptosis and the accumulation of gammaH2AX in K562 cells exposed to hydroxyurea. Likewise, a targeted genetic depletion of WT1 in primary oviduct cells does not increase the levels of gammaH2AX. Our findings position WT1 as a downstream target of the apoptotic process that occurs in response to cytotoxic forms of replicative stress and DNA damage. PMID- 29589055 TI - A walk after hemiplegia. PMID- 29589054 TI - Maintenance fluid therapy and fluid creep impose more significant fluid, sodium, and chloride burdens than resuscitation fluids in critically ill patients: a retrospective study in a tertiary mixed ICU population. AB - PURPOSE: Research on intravenous fluid therapy and its side effects, volume, sodium, and chloride overload, has focused almost exclusively on the resuscitation setting. We aimed to quantify all fluid sources in the ICU and assess fluid creep, the hidden and unintentional volume administered as a vehicle for medication or electrolytes. METHODS: We precisely recorded the volume, sodium, and chloride burdens imposed by every fluid source administered to 14,654 patients during the cumulative 103,098 days they resided in our 45-bed tertiary ICU and simulated the impact of important strategic fluid choices on patients' chloride burdens. In septic patients, we assessed the impact of the different fluid sources on cumulative fluid balance, an established marker of morbidity. RESULTS: Maintenance and replacement fluids accounted for 24.7% of the mean daily total fluid volume, thereby far exceeding resuscitation fluids (6.5%) and were the most important sources of sodium and chloride. Fluid creep represented a striking 32.6% of the mean daily total fluid volume [median 645 mL (IQR 308-1039 mL)]. Chloride levels can be more effectively reduced by adopting a hypotonic maintenance strategy [a daily difference in chloride burden of 30.8 mmol (95% CI 30.5-31.1)] than a balanced resuscitation strategy [daily difference 3.0 mmol (95% CI 2.9-3.1)]. In septic patients, non-resuscitation fluids had a larger absolute impact on cumulative fluid balance than did resuscitation fluids. CONCLUSIONS: Inadvertent daily volume, sodium, and chloride loading should be avoided when prescribing maintenance fluids in view of the vast amounts of fluid creep. This is especially important when adopting an isotonic maintenance strategy. PMID- 29589057 TI - Thomas L. Slovis (1941-2018). PMID- 29589058 TI - Combined prospectively electrocardiography- and respiratory-triggered sequential cardiac computed tomography in free-breathing children: success rate and image quality. AB - BACKGROUND: Combined prospectively electrocardiography (ECG)- and respiratory triggered sequential cardiac computed tomography (CT) has not been evaluated in free-breathing children. OBJECTIVE: To evaluate the success rate and image quality of combined prospectively ECG- and respiratory-triggered sequential cardiac CT in free-breathing children. MATERIALS AND METHODS: Image quality of combined prospectively ECG- and respiratory-triggered sequential cardiac CT in 870 children (<=5 years of age) was evaluated in terms of severe motion (maximal distance >=2 mm) and band artifacts (maximal attenuation difference >=100 Hounsfield units). The success rate of the scan mode was calculated. The causes of failed cases were assessed. Patient-related, radiation and image quality parameters were compared between success and failure groups. RESULTS: Severe motion artifacts were observed in 10.6% (92/870) of patients due to cardiac phase error in 17 (18.5%), patient motion in 12 (13.0%), and unknown causes in 63 (68.5%). Severe band artifacts were seen in 13.2% (115/870) of patients. Combined prospectively ECG- and respiratory-triggered sequential cardiac CT was successfully performed in 78.5% (683/870) of patients, while it failed in 21.5% (187/870). All the evaluated patient-related, radiation and image quality parameters were significantly different (P<=0.001) between success and failure groups except effective dose (P>0.05). CONCLUSION: Additional prospective respiratory triggering can reduce motion artifacts in prospectively ECG-triggered sequential cardiac CT in free-breathing children. PMID- 29589059 TI - Cinematic rendering of small bowel pathology: preliminary observations from this novel 3D CT visualization method. AB - 3D visualization methods for volumetric CT data have played an important role in diagnostic imaging of the small bowel, a structure which intrinsically crosses numerous slices in any 2D imaging plane. Recently, a new approach to 3D CT image creation has become available-cinematic rendering (CR). CR differs from other 3D methods in making use of a global lighting model that produces high surface detail and realistic shadowing effects that lead to 3D visualizations with photorealistic quality. Although the utility of these images for improving diagnostic accuracy has not yet been established, our group's early experience in regions of complex anatomy and pathology has been encouraging. In this pictorial review, we review the established role of 3D CT in many of the most common small bowel pathologies, provide examples of those pathologies visualized with CR, and suggest future directions for researchers to pursue. PMID- 29589061 TI - Overview of Osteoimmunology. AB - Aberrant or prolonged immune responses often affect bone metabolism. The investigation on bone destruction observed in autoimmune arthritis contributed to the development of research area on effect of the immune system on bone. A number of reports on bone phenotypes of immunocompromised mice indicate that the immune and skeletal systems share various molecules, including transcription factors, signaling molecules, and membrane receptors, suggesting the interplay between the two systems. Furthermore, much attention has been paid to the modulation of immune cells, including hematopoietic progenitor cells, by bone cells in the bone marrow. Thus, osteoimmunology which deals with the crosstalk and shared mechanisms of the bone and immune systems became the conceptual framework fundamental to a proper understanding of both systems and the development of new therapeutic strategies. PMID- 29589060 TI - Associations Between Objectively Measured Physical Activity, Body Composition and Sarcopenia: Findings from the Hertfordshire Sarcopenia Study (HSS). AB - Regular physical activity (PA) is associated with reduced risk of the development and progression of musculoskeletal, metabolic and vascular disease. However, PA declines with age and this can contribute to multiple adverse outcomes. The aims of this study were to describe the relationship between accelerometer-determined PA, body composition and sarcopenia (the loss of muscle mass and function with age). Seven-day PA was measured using the GENEactiv accelerometer among 32 men and 99 women aged 74-84 years who participated in the Hertfordshire Sarcopenia Study. We measured mean daily acceleration and minutes/day spent in non-sedentary and moderate-to-vigorous physical activity (MVPA) levels. Body composition was measured by dual-energy X-ray absorptiometry, muscle strength by grip dynamometry and function by gait speed. Sarcopenia was defined according to the EWGSOP diagnostic algorithm. Men and women spent a median (inter-quartile range) of 138.8 (82, 217) and 186 (122, 240) minutes/day engaging in non-sedentary activity but only 14.3 (1.8, 30.2) and 9.5 (2.1, 18.6) min in MVPA, respectively. Higher levels of PA were associated with reduced adiposity, faster walking speed and decreased risk of sarcopenia. For example, a standard deviation (SD) increase in mean daily acceleration was associated with an increase in walking speed of 0.25 (95% CI 0.05, 0.45) SDs and a reduction in the risk of sarcopenia of 35% (95% CI 1, 57%) in fully adjusted analyses. PA was not associated with hand grip strength. Community-dwelling older adults in this study were largely sedentary but there was evidence that higher levels of activity were associated with reduced adiposity and improved function. PA at all intensity levels in later life may help maintain physical function and protect against sarcopenia.

We investigated the effect of genotype, geographical difference, and smoking habit on NAT2 phenotype in Ethiopians. METHODS: Genotyping for NAT2 191G > A, 341 T > C, 590G > A, and 857G > A was performed in 163 unrelated healthy Ethiopians (85 living in Ethiopia and 78 living in Sweden). The NAT2 phenotype was determined using caffeine as a probe and log AFMU/(AFMU + 1X + 1 U) urinary metabolic ratio (MR) as an index. RESULTS: The frequencies of NAT2*4, *5, *6, *7, and *14 haplotypes were 14.1, 48.5, 30.1, 5.5, and 1.8%, respectively. The frequencies of rapid (NAT2*4/*4), intermediate (heterozygous *4), and slow (no *4 allele) acetylator genotypes were 1.8, 24.6, and 73.6%, respectively. The distribution NAT2 MR was bimodal with 70% being phenotypically slow acetylators. NAT2 genotype (p < 0.0001) and country of residence (p = 0.004) independently predicted NAT2 phenotype. Controlling for the effect of genotype, ethnic Ethiopians living in Ethiopia had significantly higher NAT2 MR than those living in Sweden (p = 0.006). NAT2 genotype-phenotype concordance rate was 75%. Distinct country-of-residence-based genotype-phenotype discordance was observed. The proportion of phenotypically determined rapid acetylators was significantly higher and slow acetylators was lower in Ethiopians living in Ethiopia (39% rapid, 61% slow) than in Sweden (20% rapid, 80% slow). Sex and smoking had no significant effect on NAT2 MR. CONCLUSIONS: We report a high prevalence of NAT 2 slow acetylators in Ethiopians and a conditional NAT2 genotype-phenotype discordance implicating a partial phenotype conversion and metabolic adaptation. Gene-environment interactions regulate NAT2 phenotype. PMID- 29589063 TI - Patterns of direct oral anticoagulant drug prescription in France in 2010-2013: a study in the Midi-Pyrenees area. AB - AIM: The aim of our study was to study the pattern of prescription of direct acting oral anticoagulants (DOACs) according to the French recommendations. METHODS: We performed a cross-sectional study using anonymous data of patients covered by the French National Health Insurance information system (SNIIRAM) from 1 January 2010 to 31 December 2013 in the area of Midi-Pyrenees (southwest of France). RESULTS: Of the 355,608 patients identified, 325,216 (91.5%) were included, of whom 22,142 received at least one DOAC. About 39.1% (8,652 patients) had DOAC in an orthopedic indication, 46.5% (10,303 patients) in a cardiac indication, and 16.1% (3568 patients) in an indeterminate indication. Overall, guidelines were largely followed as for renal function monitoring, prescribing in orthopedic indications, in cardiac indications in patients aged 80 years and older, and in the case of concomitant use of verapamil. However, inappropriate prescriptions were observed for cardiac indications, and for dosage adjustments in orthopedic indications, with respect to both the age of patients (75 years and older) and those taking verapamil or amiodarone concomitantly. Guidelines were more followed in women and patients aged 80 or more. CONCLUSIONS: Among patients receiving DOACs, 58% were exposed to a prescription falling outside the guidelines. This study on DOAC prescription patterns revealed insufficiencies in the compliance with the French guidelines in certain indications. PMID- 29589064 TI - Recent major advances in cardiovascular pharmacotherapy. AB - The field of cardiovascular pharmacotherapy remains extremely active. The aim of this review is to summarize the recent major advances in cardiovascular pharmacotherapy, with a focus on (1) the new approved drug for treatment of heart failure with reduced ejection fraction-sacubitril/valsartan; (2) proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors; (3) the novel reversal agents for non-vitamin K oral anticoagulants (NOACs); and finally, (4) new evidence on pharmacological treatment of coronary artery disease. PMID- 29589065 TI - Relationship between frailty, polypharmacy, and underprescription in older adults living in nursing homes. AB - PURPOSE: Frailty, polypharmacy, and underprescription are considered a major matter of concern in nursing homes, but the possible relationships between them are not well known. The aim is to examine the possible association between medication underprescription, polypharmacy, and frailty in older people living in nursing homes. METHODS: A cross-sectional analysis from a concurrent cohort study, including 110 subjects >= 65 years living in two nursing homes. Four frailty scales were applied; polypharmacy was defined as >= 5 medications and underprescription was measured with Screening Tool to Alert to Right Treatment (START) criteria. Logistic regression models were performed to assess the associations. RESULTS: The mean age was 86.3 years (SD 7.3) and 71.8% were female. 73.6% of subjects took >= 5 chronic medications and 60.9% met one or more START criteria. The non-frail participants took more medications than the frail subjects according to the imputated frailty Fried criteria (8.1 vs 6.7, p = 0.042) and the FRAIL-NH scale (7.8 vs 6.8, p = 0.026). Multivariate analyses did not find an association between frailty and polypharmacy. Frail participants according to the Fried criteria met a higher number of START criteria (1.9 vs 1.0, p = 0.017), and had a higher prevalence of underprescription (87.5 vs 50.0%), reaching the limit of statistical significance in multivariate analysis. CONCLUSION: The positive association found in previous studies between frailty and polypharmacy cannot be extrapolated to institutionalized populations. There is a trend towards higher rates of underprescription in frail subjects. Underprescription in frail older adults should be redefined and new strategies to measure it should be developed. PMID- 29589067 TI - Clozapine-related neutropenia, myocarditis and cardiomyopathy adverse event reports in Australia 1993-2014. AB - RATIONALE: Clozapine is the gold-standard medicine for treating refractory schizophrenia but there are some notable serious adverse events (AE). We aimed to analyse reported rates of clozapine cardiac and haematological AEs in Australia. METHODS: Using data from the Therapeutic Goods Administration, we examined all reported clozapine AEs (1993-2014) with a specific focus on neutropenia, myocarditis and cardiomyopathy. We related AEs to clozapine-dispensing data in Queensland, scaled up to Australia. RESULTS: There were 8561 AEs reported: neutropenia (13.7%), myocarditis (9.3%) and cardiomyopathy (3.8%). Reported rates of myocarditis and cardiomyopathy increased after 1999 following a myocarditis case series from Sydney. Cardiomyopathy AE rates have remained stable since then but myocarditis AEs have increased steadily. Neutropenia was more common in women, while cardiomyopathy and myocarditis were more common in men. There were five reported deaths from neutropenia and cardiomyopathy. CONCLUSIONS: The rates of serious AEs (including deaths) are low and likely an underestimate of true rates and need to be considered by clinicians in balancing the risks and benefits. Continued education on the monitoring and treatment of these AEs for consumers, carers and health professionals is essential and reporting these to the relevant national reporting agency is crucial. PMID- 29589066 TI - Potentially inappropriate medication in the elderly: a systematic review of validated explicit criteria. AB - PURPOSE: Potentially inappropriate medication (PIM) use causes preventable adverse drug reactions in older patients. Several assessment tools have been published to identify and avoid PIM use. In this systematic literature review, we aim to provide summaries and comparisons of validated PIMs lists published between 1991 and 2017 internationally. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA), we performed a systematic review of articles describing the development and validation of criteria for identification of PIMs among older people published between January 1991 and April 2017. The searches were conducted on PUBMED, AgeLine, Academic Search, Academic Search Premier, and CINAHL. We identified the most common medications/classes described as PIM. We also identified the drug disease interactions and drug-drug interactions reported among criteria. RESULTS: From 2933 articles screened, 36 met our inclusion criteria. The majority used the Delphi method to validate their criteria. We identified 907 different medications/classes, 536 different drug disease interactions involving 84 diseases/conditions, and 159 drug-drug interactions. Benzodiazepines and nonsteroidal anti-inflammatory drugs were the medications most commonly reported as potentially inappropriate for older people. CONCLUSION: Although approaches aimed at detecting inappropriate prescribing have intensified in recent years, we observed limited overlap between different PIM lists. Additionally, some PIM lists did not provide special considerations of use and alternative therapies to avoid PIMs. These facts may compromise the use of PIM lists in clinical practice. Future PIM lists should integrate information about alternative therapies and special considerations of use in order to help clinicians in the drug prescription. PMID- 29589068 TI - A history of binge drinking during adolescence is associated with poorer sleep quality in young adult Mexican Americans and American Indians. AB - RATIONALE: Binge drinking during adolescence is common, and adolescents and young adults with alcohol problems may also have sleep difficulties. However, few studies have documented the effects of a history of adolescent binge drinking on sleep in young adulthood in high-risk minority populations. OBJECTIVES: To quantify sleep disturbance, as indexed by the Pittsburgh Sleep Quality Index (PSQI), in a sample of young adult Mexican American and American Indian men and women (18-30 years, n = 800) with and without a history of alcohol binge drinking during adolescence, controlling for age, gender, and race. RESULTS: Gender was found to affect PSQI responses with females reporting waking up at night, having more bad dreams, and later habitual bedtimes than males, and males reporting more problems with breathing and snoring. Increasing age was associated with snoring or coughing, less hours spent in bed, and later evening bedtimes. Race also influenced the PSQI with American Indians reporting longer sleep latencies and sleep durations, more hours spent in bed, and more trouble with coughing and snoring than Mexican Americans, and Mexican Americans reporting later bedtimes. A history of adolescent regular binge drinking was associated with longer sleep latencies, more problems with breathing, bad dreams, and an overall higher PSQI total score, when controlling for age, race, and gender. CONCLUSIONS: This report suggests, like what has been found in young adults in general population samples, that binge drinking during adolescence is associated with deleterious consequences on sleep quality in young adulthood in these high-risk and understudied ethnic groups. PMID- 29589069 TI - Effect of gabapentin on sleep and delta and theta EEG power in adult rats exposed to chronic intermittent ethanol vapor and protracted withdrawal during adolescence. AB - RATIONALE: Adolescents and young adults with alcohol problems may also have sleep difficulties. However, whether these sleep problems are a result of a history of drinking or arise due to other comorbid disorders is difficult to disentangle in human studies. Additionally, the mechanisms underlying adolescent alcohol-induced sleep disturbances and potential targets for therapy also remain under investigated. Recent clinical trials have demonstrated that the anticonvulsant and analgesic drug gabapentin may have therapeutic value in normalizing sleep quality in adult recovering alcoholics, yet its potential for the treatment of adolescent sleep disturbances has not been investigated. OBJECTIVES: This study sought to evaluate the effects of a history of 5 weeks of chronic intermittent ethanol vapor exposure, administered during adolescence (AIE), on EEG sleep, in young adult rats (n = 29). The ability of two doses of gabapentin (30, 120 mg/kg) to modify sleep and slow wave activity were also investigated in these young adult rats exposed to alcohol vapor during adolescence. RESULTS: Adolescent vapor exposure in the rat was found to result in deficits in delta (1-4 Hz) and theta (4-8 Hz) power during slow wave sleep. Administration of gabapentin caused a "normalization" of the delta power deficits but did not affect theta power. CONCLUSIONS: This report suggests that the potential mechanisms and therapeutic targets for sleep disturbance associated with adolescent alcohol exposure can be studied in preclinical models and that gabapentin may show partial efficacy in ameliorating these sleep deficits. PMID- 29589070 TI - Vitamin A-coupled liposomes carrying TLR4-silencing shRNA induce apoptosis of pancreatic stellate cells and resolution of pancreatic fibrosis. AB - : Chronic pancreatitis leads to irreversible damage in pancreatic endocrine and exocrine functions. However, there is no clinically available antifibrotic drug. Pancreatic stellate cells (PSCs) can be activated by Toll-like receptor 4 (TLR4) responses to its ligands and they contribute to the formation of pancreatic fibrosis. Silencing the expression of TLR4 in PSCs by RNAi may be a novel therapeutic strategy for the treatment of pancreatic fibrosis. In addition, PSCs have a remarkable capacity for vitamin A uptake most likely through cellular retinol binding protein (CRBP). In our study, to ensure the efficient delivery of RNAi therapeutic agents to PSCs, VitA-coupled liposomes (VA-lips) were used as drug carriers to deliver plasmids expressing TLR4-specific short hairpin RNA (shRNA) to treat pancreatic fibrosis. Our study demonstrated that silencing the expression of TLR4 could induce mitochondrial apoptosis in aPSCs and might be an effective therapeutic strategy for the treatment of pancreatic fibrosis. KEY MESSAGES: VA-lip-shRNA-TLR4 recovers pancreatic tissue damage. VA-lip-shRNA-TLR4 resolution of pancreatic fibrosis. VA-lip-shRNA-TLR4 accelerates ECM degradation and inhibits ECM synthesis. Silencing TLR4 induces aPSCs mitochondrial apoptosis. Silencing TLR4 inhibits the activation of NF-kappaB. PMID- 29589071 TI - Distribution of IL-1beta immunoreactive cells in pancreatic biopsies from living volunteers with new-onset type 1 diabetes: comparison with donors without diabetes and with longer duration of disease. AB - AIMS/HYPOTHESIS: Although IL-1beta is considered a key mediator of beta cell destruction, its cellular expression in islets during early type 1 diabetes remains unclear. We compared its expression in rare pancreatic biopsies from new onset living volunteers with its expression in cadaveric pancreas sections from non-diabetic autoantibody-positive and -negative individuals and those with long standing disease. METHODS: Pancreatic biopsy sections from six new-onset living volunteers (group 1) and cadaveric sections from 13 non-diabetic autoantibody negative donors (group 2), four non-diabetic autoantibody-positive donors (group 3) and nine donors with diabetes of longer duration (0.25-12 years of disease; group 4) were triple-immunostained for IL-1beta, insulin and glucagon. Intra- and peri-islet IL-1beta-positive cells in insulin-positive and -negative islets and in random exocrine fields were enumerated. RESULTS: The mean number of IL-1beta positive cells per islet from each donor in peri- and intra-islet regions was <1.25 and <0.5, respectively. In all study groups, the percentage of islets with IL-1beta cells in peri- and/or intra-islet regions was highly variable and ranged from 4.48% to 17.59% in group 1, 1.42% to 44.26% in group 2, 7.93% to 17.53% in group 3 and 3.85% to 42.86% in group 4, except in a single case where the value was 75%. In 25/32 donors, a higher percentage of islets showed IL-1beta-positive cells in peri-islet than in intra-islet regions. In sections from diabetic donors (groups 1 and 4), a higher mean number of IL-1beta-positive cells occurred in insulin-positive islets than in insulin-negative islets. In group 2, 70-90% of islets in 3/13 sections had weak-to-moderate IL-1beta staining in alpha cells but staining was virtually absent or substantially reduced in the remaining groups. The mean number of exocrine IL-1beta-positive cells in group 1 was lower than in the other groups. CONCLUSIONS/INTERPRETATION: At onset of type 1 diabetes, the low number of islet-associated IL-1beta-positive cells may be insufficient to elicit beta cell destruction. The variable expression in alpha cells in groups 2 4 suggests their cellular heterogeneity and probable physiological role. The significance of a higher but variable number of exocrine IL-1beta-positive cells seen in non-diabetic individuals and those with long-term type 1 diabetes remains unclear. PMID- 29589072 TI - The resident macrophages in murine pancreatic islets are constantly probing their local environment, capturing beta cell granules and blood particles. AB - AIMS/HYPOTHESIS: We studied here the interactions between the resident macrophages of pancreatic islets with beta cells and the blood vasculature. We also examined the immunological consequences of such interactions. METHODS: Islets were isolated from C57BL/6 mice expressing CX3C motif chemokine receptor 1 green fluorescent protein (CX3CR-GFP) and examined live by two-photon microscopy. Islets were also examined by electron microscopy to study the relationship of the intra-islet macrophages with the beta cells. In NOD.Rag1-/- mice and young (non diabetic) male mice, the acquisition of beta cell granules was tested functionally by probing with CD4+ T cells directed against insulin epitopes. RESULTS: Two-photon microscopy showed that the islet resident macrophages were in close contact with blood vessels and had extensive filopodial activity. Some filopodia had direct access to the vessel lumen and captured microparticles. Addition of glucose at high concentration reduced the degree of filopodia sampling of islets. This finding applied to in vivo injection of glucose or to in vitro cultures. Ultrastructural examination showed the close contacts of macrophages with beta cells. Such macrophages contained intact dense core granules. Functional studies in NOD mice indicated that the macrophages presented insulin peptides to insulin-reactive T cells. Presentation was increased after glucose challenge either ex vivo or after an in vivo pulse. In agreement with the morphological findings, presentation was not affected by insulin receptor blockade. CONCLUSIONS/INTERPRETATION: Islet resident macrophages are highly active, sampling large areas of the islets and blood contents and capturing beta cell granules. After such interactions, macrophages present immunogenic insulin to specific autoreactive T cells.

PMID- 29589073 TI - Overweight, obesity and the risk of LADA: results from a Swedish case-control study and the Norwegian HUNT Study. AB - AIMS/HYPOTHESIS: Excessive weight is a risk factor for type 2 diabetes, but its role in the promotion of autoimmune diabetes is not clear. We investigated the risk of latent autoimmune diabetes in adults (LADA) in relation to overweight/obesity in two large population-based studies. METHODS: Analyses were based on incident cases of LADA (n = 425) and type 2 diabetes (n = 1420), and 1704 randomly selected control participants from a Swedish case-control study and prospective data from the Norwegian HUNT Study including 147 people with LADA and 1,012,957 person-years of follow-up (1984-2008). We present adjusted ORs and HRs with 95% CI. RESULTS: In the Swedish data, obesity was associated with an increased risk of LADA (OR 2.93, 95% CI 2.17, 3.97), which was even stronger for type 2 diabetes (OR 18.88, 95% CI 14.29, 24.94). The association was stronger in LADA with low GAD antibody (GADA; 2 years is associated with a significantly better prognosis. PMID- 29589078 TI - Effects of a cognitive dual task on variability and local dynamic stability in sustained repetitive arm movements using principal component analysis: a pilot study. AB - In many daily jobs, repetitive arm movements are performed for extended periods of time under continuous cognitive demands. Even highly monotonous tasks exhibit an inherent motor variability and subtle fluctuations in movement stability. Variability and stability are different aspects of system dynamics, whose magnitude may be further affected by a cognitive load. Thus, the aim of the study was to explore and compare the effects of a cognitive dual task on the variability and local dynamic stability in a repetitive bimanual task. Thirteen healthy volunteers performed the repetitive motor task with and without a concurrent cognitive task of counting aloud backwards in multiples of three. Upper-body 3D kinematics were collected and postural reconfigurations-the variability related to the volunteer's postural change-were determined through a principal component analysis-based procedure. Subsequently, the most salient component was selected for the analysis of (1) cycle-to-cycle spatial and temporal variability, and (2) local dynamic stability as reflected by the largest Lyapunov exponent. Finally, end-point variability was evaluated as a control measure. The dual cognitive task proved to increase the temporal variability and reduce the local dynamic stability, marginally decrease endpoint variability, and substantially lower the incidence of postural reconfigurations. Particularly, the latter effect is considered to be relevant for the prevention of work-related musculoskeletal disorders since reduced variability in sustained repetitive tasks might increase the risk of overuse injuries. PMID- 29589079 TI - Kinematics of ventrally mediated grasp-to-eat actions: right-hand advantage is dependent on dorsal stream input. AB - Studies have suggested a left-hemisphere specialization for visually guided grasp to-eat actions by way of task-dependent kinematic asymmetries (i.e., smaller maximum grip apertures for right-handed grasp-to-eat movements than for right handed grasp-to-place movements or left-handed movements of either type). It is unknown, however, whether this left-hemisphere/right-hand kinematic advantage is reliant on the dorsal "vision-for-action" visual stream. The present study investigates the kinematic differences between grasp-to-eat and grasp-to place actions performance during closed-loop (i.e., dorsally mediated) and open-loop delay (i.e., ventrally mediated) conditions. Twenty-one right-handed adult participants were asked to reach to grasp small food items to (1) eat them, or (2) place them in a container below the mouth. Grasps were performed in both closed-loop and open-loop delay conditions, in separate sessions. We show that participants displayed the right-hand grasp-to-eat kinematic advantage in the closed-loop condition, but not in the open-loop delay condition. As no task dependent kinematic differences were found in ventrally mediated grasps, we posit that the left-hemisphere/right-hand advantage is dependent on dorsal stream processing. PMID- 29589080 TI - Postural time-to-contact as a precursor of visually induced motion sickness. AB - The postural instability theory of motion sickness predicts that subjective symptoms of motion sickness will be preceded by unstable control of posture. In previous studies, this prediction has been confirmed with measures of the spatial magnitude and the temporal dynamics of postural activity. In the present study, we examine whether precursors of visually induced motion sickness might exist in postural time-to-contact, a measure of postural activity that is related to the risk of falling. Standing participants were exposed to oscillating visual motion stimuli in a standard laboratory protocol. Both before and during exposure to visual motion stimuli, we monitored the kinematics of the body's center of pressure. We predicted that postural activity would differ between participants who reported motion sickness and those who did not, and that these differences would exist before participants experienced subjective symptoms of motion sickness. During exposure to visual motion stimuli, the multifractality of sway differed between the Well and Sick groups. Postural time-to-contact differed between the Well and Sick groups during exposure to visual motion stimuli, but also before exposure to any motion stimuli. The results provide a qualitatively new type of support for the postural instability theory of motion sickness. PMID- 29589084 TI - Soft tissue tension is four times lower in the unstable primary total hip arthroplasty. AB - PURPOSE: The aim was to compare patients who suffered recurrent dislocation following total hip arthroplasty (THA) with those who did not to clarify the degree of soft tissue tension in dislocation patients. METHODS: The subjects were 18 hips with recurrent dislocation (unstable THA group) and 37 hips without dislocation (stable THA group). To evaluate soft tissue tension, radiographs were taken while applying distal traction at traction forces of 40, 30, and 20% of the body weight (BW) and femoral head displacement was measured. Acetabular offset, femoral offset, limb offset, and leg length discrepancy were measured in patients with a normal contralateral hip joint. RESULTS: The mean femoral head displacement in the unstable THA group was 5.6 mm at 40% of the BW, 4.6 mm at 30% of the BW, and 3.5 mm at 20% of the BW. In the stable THA group, the mean femoral head displacement was 1.4 mm at 40% of the BW, 1.1 mm at 30% of the BW, and 0.9 mm at 20% of the BW. Significant differences were seen between the groups at all traction forces. Furthermore, on comparing the unstable and stable THA groups, femoral offset was found to significantly be smaller in the affected side than in the healthy side in the unstable THA group. CONCLUSIONS: We found that soft tissue tension is approximately fourfold lower in patients exhibiting recurrent dislocations following THA than in patients exhibiting no dislocations and that femoral offset was related to decreased soft tissue tension. PMID- 29589085 TI - Real-time computerised tomography assisted porous tantalum implant in ARCO stage I-II non-traumatic osteonecrosis of the femoral head: minimum five-year follow up. AB - PURPOSES: This study was established to investigate the medium-term clinical effect of real-time CT assisted porous tantalum implant for the treatment of ARCO stage I-II non-traumatic osteonecrosis of the femoral head (ONFH). METHODS: This study comprised 24 ONFH patients (29 hips) who were treated with intra-operative real-time CT accurate rapid positioning assisted drilling decompression, lesion removal and porous tantalum implant. Harris score, VAS score and imaging in pre operation and follow-up period were recorded. RESULTS: The average operative time and intra-operative blood loss were 72.6 min and 158.8 ml, respectively. The mean follow-up was 5.4 years. No femoral head penetrating, wound infection, and death occurred. Harris and VAS score improved significantly (73.78 vs. 88.11; 7.13 vs. 2.66) at last follow-up (P < 0.05). The functional improvement and pain relief rate was 100% at six months after operation. The effective rate was 86.21% at 12 months after operation and last follow-up. Five pre-operative ARCO stage I hips had no radiographic progress. Meanwhile, four among the 24 ARCO stage II hips progressed into stage III between eight and 12 months after surgery, among which two progressed into stage IV and two remained in stage III at the last follow-up. The average value of Kerboul combined necrotic angle was 263.24 degrees . There was no progress in Kerboul combined necrotic angle among the grades 2 and 3 patients. However, among the six cases at grade 4, four cases with post-operative progress, two patients converted to THA. CONCLUSIONS: Our technique is safety and effective in the treatment of ARCO stage I-II non-traumatic ONFH. PMID- 29589086 TI - Subchondral stem cell therapy versus contralateral total knee arthroplasty for osteoarthritis following secondary osteonecrosis of the knee. AB - PURPOSE: Total knee arthroplasty (TKA) implanted in patients with secondary osteonecrosis (ON) related to corticosteroids have relatively poor outcome (20% revision rate) at a mean follow-up of only eight years. With the hypothesis that subchondral bone marrow injection might improve knees in these patients, we evaluated 30 patients who had bilateral knee osteoarthritis with severe joint space narrowing and received TKA in one knee and subchondral bone marrow concentrate injection in the contralateral knee. MATERIAL AND METHODS: A prospective randomized controlled clinical trial was carried out in 60 knees of 30 patients (mean age 28 years, 18-41) who presented bilateral osteoarthritis secondary to knee ON related to corticosteroids in relation with different severe medical conditions. During the same anesthesia, one knee received TKA; for the other knee, a bone marrow graft containing an average of 6500 MSCs/mL (counted as CFU-F, range 3420 to 9830) was delivered to the subchondral bone of the femur and tibia. The length of anesthesia related to each procedure (bone marrow aspiration and subchondral injection of concentrated bone marrow versus total knee arthroplasty) was measured. Peri-operative outcomes, morbidity, complications, and safety of the two procedures were compared. Subsequent admissions for revision surgery were identified. At the most recent follow-up (average of 12 years, range 8 to 16 years), clinical outcomes of the patient (Knee Society score) were obtained along with radiological imaging outcomes (MRIs for knees with subchondral bone marrow injection). RESULTS: Anesthesia related to the TKA side was longer than for the cell therapy group. Medical and surgical complications were more frequent after TKA. A higher number of thrombophlebitis was observed on the side with TKA (15%) versus none on the side with cell therapy (0%). At the most recent follow-up (average of 12 years, range 8 to 16 years), six (out of 30) TKA knees needed subsequent surgery versus only one with cell therapy. The Knee Score had improved and remained similar in the TKA and cell therapy groups (respectively 80.3 points +/- 11 versus 78.3 +/- 23); 21 patients preferred the knee with cell therapy and 9 preferred the knee with TKA. Knees with cell therapy had improvement on cartilage and bone marrow lesions observed at the site of bone marrow subchondral injection. CONCLUSIONS: Subchondral autologous bone marrow concentrate was an effective procedure for treating young patients with knee osteoarthritis following secondary ON of the knee related to corticosteroids with a lower complication rate and a quicker recovery as compared with TKA. PMID- 29589087 TI - Imbalanced bone turnover markers and low bone mineral density in patients with osteonecrosis of the femoral head. AB - PURPOSE: There have been few studies investigating the cumulative effect of individual factors related to bone metabolism on the systemic balance between bone formation and resorption in patients with osteonecrosis of the femoral head (ONFH). We investigated bone mineral density (BMD) of lumbar spine and bone turnover markers that reflect systemic bone metabolism. METHODS: Two-hundred twenty patients with ONFH were matched to 220 healthy subjects according to age, gender, and body mass index. ONFH patients were divided into steroid-induced (18%), alcoholic (21%), and idiopathic ONFH (61%) and subgroup analysis was performed to exclude the effect of steroid and malnutrition on bone metabolism. We compared lumbar spine bone mineral density (BMD) between groups and measured serum bone-specific alkaline phosphatase (BALP) and urinary deoxypyridinoline/creatinine (Dpd/Cr) ratio. RESULTS: Logistic regression analysis revealed low spine BMD was significantly associated with each subgroup of ONFH when compared with that of the control group (odds ratio of 2.27, 4.24, and 1.86 in alcoholic, steroid, and idiopathic ONFH, respectively). The mean value of serum BALP (27.02 U/L) was within the normal reference range while average urine Dpd/Cr ratio (6.24 nM/mM) increased in ONFH group when compared with respective reference range. CONCLUSION: Spine BMD decreased and urinary Dpd/Cr ratio increased in patients with non-traumatic ONFH. Further studies will be necessary to identify whether non-traumatic ONFH is merely a regional disease confined to the femoral head or may affect systemic bone metabolism. PMID- 29589088 TI - Total knee arthroplasties from the origin to navigation: history, rationale, indications. AB - Since the early 1970s, total knee arthroplasties have undergone many changes in both their design and their surgical instrumentation. It soon became apparent that to improve prosthesis durability, it was essential to have instruments which allowed them to be fitted reliably and consistently. Despite increasingly sophisticated surgical techniques, preoperative objectives were only met in 75% of cases, which led to the development, in the early 1990s, in Grenoble (France), of computer-assisted orthopaedic surgery for knee prosthesis implantation. In the early 2000s, many navigation systems emerged, some including pre-operative imagery ("CT-based"), others using intra-operative imagery ("fluoroscopy-based"), and yet others with no imagery at all ("imageless"), which soon became the navigation "gold standard". They use an optoelectronic tracker, markers which are fixed solidly to the bones and instruments, and a navigation workstation (computer), with a control system (e.g. pedal). Despite numerous studies demonstrating the benefit of computer navigation in meeting preoperative objectives, such systems have not yet achieved the success they warrant, for various reasons we will be covering in this article. If the latest navigation systems prove to be as effective as the older systems, they should give this type of technology a well-deserved boost. PMID- 29589090 TI - ?

Tetraspanins affect various biological functions, but how tetraspanins engage in multi-faceted functions at the cellular level is largely unknown. When cells interact, the membrane microextrusions at the cell-cell interfaces form dynamic, digit-like structures between cells, which we term digitation junctions (DJs). We found that (1) tetraspanins CD9, CD81, and CD82 and (2) TEM-associated molecules integrin alpha3beta1, CD44, EWI2/PGRL, and PI-4P are present in DJs of epithelial, endothelial, and cancer cells. Tetraspanins and their associated molecules also regulate the formation and development of DJs. Moreover, (1) actin cytoskeleton, RhoA, and actomyosin activities and (2) growth factor receptor-Src MAP kinase signaling, but not PI-3 kinase, regulate DJs. Finally, we showed that DJs consist of various forms in different cells. Thus, DJs are common, interactive structures between cells, and likely affect cell adhesion, migration, and communication. TEMs probably modulate various cell functions through DJs. Our findings highlight that DJ morphogenesis reflects the transition between cell matrix adhesion and cell-cell adhesion and involves both cell-cell and cell matrix adhesion molecules.

PMID- 29589093 TI - The bZIP transcriptional factor activator protein-1 regulates Metarhizium rileyi morphology and mediates microsclerotia formation. AB - Internal oxidative stress can trigger microsclerotia (MS) formation of Metarhizium rileyi in liquid culture. Activator protein 1 (AP1) is a transcription factor and an important determinant of the response to oxidative stress. To investigate how M. rileyi responds to internal oxidative stress and how MS development is regulated, the Mrap1 gene was characterized. Mrap1 was highly expressed during periods of invasive hyphal growth and in response to changing culture conditions during MS development. Compared with the wild-type and complemented strains, DeltaMrap1 mutants exhibited various defects in aerial hyphal growth, yeast-to-hypha transition, and conidia and MS formation. DeltaMrap1 mutants also displayed sensitivity to oxidative stress, were morphologically abnormal, and responded differently to oxidative stress during MS development. DeltaMrap1 mutants had significantly reduced conidial (74-82%) and MS (99%) yields. Insect bioassays revealed that DeltaMrap1 mutants displayed reduced virulence in topical (43-76%) and injection (45-70%) bioassays. Moreover, the ability of DeltaMrap1 mutants to grow out of the cuticle was reduced due to impaired conidiation on the host cadaver. Digital gene expression profiling revealed that genes involved in antioxidation, pigment biosynthesis, and ion transport were regulated by Mrap1 during MS development. Taken together, our results confirm the importance of Mrap1 in vegetative growth, conidia and MS formation, and virulence.

Extensive research has been conducted on cancer; regardless, the link between cancer and diet remains undetermined. Recent studies have emphasized the importance of miRNAs in cancer-associated pathways from the perspective of dietary modulation. We highlighted the recent data on dietary modulation of gut microbiota and miRNAs related to cancer on the basis of recently published results. The targets of miRNAs are oncogenes or tumor suppressors that mediate the progression and initiation of carcinogenesis. Different miRNAs display complex expression profiles in response to dietary manipulation. Various dietary components, such as fatty acids, resveratrol, isothiocyanate, and curcumin, have been effectively used in cancer prevention and treatment. This potency is attributed to the capability of these components to alter miRNA expression, thereby modulating the vital pathways involved in metastasis, invasion, apoptosis, tumor growth, and cell proliferation.

AB - Nanotechnology has emerged as a prominent scientific discipline in the technological revolution of this millennium. The scientific community has focused on the green synthesis of metal nanoparticles as compared to physical and chemical methods due to its eco-friendly nature and high efficacy. Medicinal plants have been proven as the paramount source of various phytochemicals that can be used for the biogenic synthesis of colloidal silver and gold nanoparticles as compared to other living organisms, e.g., microbes and fungi. According to various scientific reports, the biogenic nanoparticles have shown promising potential as wound healing agents. However, not a single broad review article was present that demonstrates the wound healing application of biogenic silver and gold nanoparticles. Foreseeing the overall literature published, we for the first time intended to discuss the current trends in wound healing via biogenic silver and gold nanoparticles. Furthermore, light has been shed on the mechanistic aspects of wound healing along with futuristic discussion on the faith of biogenic silver and gold nanoparticles as potential wound healing agents. PMID- 29589096 TI - The history of the formation of the Pan African paediatric surgical Association (PAPSA). AB - Political change in the 1990s in Southern Africa influenced the long awaited formation of a children's surgical association in Africa. Here, within is the historical account of the formation of the Pan African Association of Paediatric Surgeons (PAPSA). The basis of the argument for the formation of PAPSA was that paediatric surgeons from Africa have a wealth of experience and special knowledge of diseases affecting children in the African continent which differ substantially from those encountered in other regions of the world. This historical account is mainly from documentation by 2 of the organisations founding members. PMID- 29589097 TI - An intronic VNTR affects splicing of ABCA7 and increases risk of Alzheimer's disease. AB - Mutations leading to premature termination codons in ATP-Binding Cassette Subfamily A Member 7 (ABCA7) are high penetrant risk factors of Alzheimer's disease (AD). The influence of other genetic variants in ABCA7 and downstream functional mechanisms, however, is poorly understood. To address this knowledge gap, we investigated tandem repetitive regions in ABCA7 in a Belgian cohort of 1529 AD patients and control individuals and identified an intronic variable number tandem repeat (VNTR). We observed strong association between VNTR length and a genome-wide associated signal for AD in the ABCA7 locus. Expanded VNTR alleles were highly enriched in AD patients [odds ratio = 4.5 (1.3-24.2)], and VNTR length inversely correlated with amyloid beta1-42 in cerebrospinal fluid and ABCA7 expression. In addition, we identified three novel ABCA7 alternative splicing events. One isoform in particular-which is formed through exon 19 skipping-lacks the first nucleotide binding domain of ABCA7 and is abundant in brain tissue. We observed a tight correlation between exon 19 skipping and VNTR length. Our findings underline the importance of studying repetitive DNA in complex disorders and expand the contribution of genetic and transcript variation in ABCA7 to AD. PMID- 29589098 TI - Two-Year Clinical Outcomes of the CONSEQUENT Trial: Can Femoropopliteal Lesions be Treated with Sustainable Clinical Results that are Economically Sound? AB - PURPOSE: The previously reported 6-month angiographic and 12-month clinical outcomes of the CONSEQUENT trial demonstrated the safety and efficacy of a novel paclitaxel-resveratrol-coated balloon for the treatment of lesions in the femoropopliteal segment. The purpose of this report is to present the 2-year results including a cost-benefit analysis for Germany. MATERIALS AND METHODS: Patients with symptomatic peripheral artery occlusive disease in femoropopliteal lesions were randomized either to drug-coated balloon (DCB, n = 78) or plain old balloon angioplasty (POBA, n = 75). As secondary endpoints, the 2-year clinical results consisting of target lesion revascularization (TLR), patency and increase in walking distance were recorded. Based on the Kaplan-Meier analyses for TLR and other adverse events, a cost-benefit analysis was conducted for the German DRG system. RESULTS: There were no additional TLRs in both groups between 14 and 24 months so that the corresponding rates remained significantly different between the treatment groups (DCB: 19.1 vs. POBA 40.6%, p = 0.007). At 2 years, the patency rate was significantly higher in the DCB group (72.3 vs. 48.4%, p = 0.006). The walking distance increase was also significantly higher after DCB angioplasty (172 +/- 103 vs. 52 +/- 136 m, p = 0.001). We estimated 2-year cost savings of ? 1111.97 per patient treated with DCB instead of POBA. CONCLUSIONS: The use of paclitaxel-resveratrol matrix-coated peripheral balloons compared to POBA was associated with a significantly reduced TLR rate, superior patency and substantial cost savings at 2 years.

AB - BACKGROUND: Peripancreatic collections occur frequently after distal pancreatectomy. However, the sequelae of peripancreatic collections vary from case to case, and their clinical impact is uncertain. In this study, the correlations between CT findings of peripancreatic collections and complications after distal pancreatectomy were investigated. METHODS: Ninety-six consecutive patients who had undergone distal pancreatectomy between 2010 and 2015 were retrospectively investigated. The extent and heterogeneity of peripancreatic collections and background clinicopathological characteristics were analyzed. The extent of peripancreatic collections was calculated based on three-dimensional computed tomography images, and the degree of heterogeneity of peripancreatic collections was assessed based on the standard deviation of their density on computed tomography. RESULTS: Of 85 patients who underwent postoperative computed tomography imaging, a peripancreatic collection was detected in 77 (91%). Patients with either a large extent or a high degree of heterogeneity of peripancreatic collection had a significantly higher rate of clinically relevant pancreatic fistula than those without (odds ratio 5.95, 95% confidence interval 2.12-19.72, p = 0.001; odds ratio 8.0, 95% confidence interval 2.87-24.19, p = 0.0001, respectively). CONCLUSIONS: A large and heterogeneous peripancreatic collection was significantly associated with postoperative complications, especially clinically relevant postoperative pancreatic fistula. A small and homogenous peripancreatic collection could be safely observed. PMID- 29589100 TI - Genetic susceptibility to neuroblastoma: current knowledge and future directions. AB - Neuroblastoma, a malignancy of the developing peripheral nervous system that affects infants and young children, is a complex genetic disease. Over the past two decades, significant progress has been made toward understanding the genetic determinants that predispose to this often lethal childhood cancer. Approximately 1-2% of neuroblastomas are inherited in an autosomal dominant fashion and a combination of co-morbidity and linkage studies has led to the identification of germline mutations in PHOX2B and ALK as the major genetic contributors to this familial neuroblastoma subset. The genetic basis of "sporadic" neuroblastoma is being studied through a large genome-wide association study (GWAS). These efforts have led to the discovery of many common susceptibility alleles, each with modest effect size, associated with the development and progression of sporadic neuroblastoma. More recently, next-generation sequencing efforts have expanded the list of potential neuroblastoma-predisposing mutations to include rare germline variants with a predicted larger effect size. The evolving characterization of neuroblastoma's genetic basis has led to a deeper understanding of the molecular events driving tumorigenesis, more precise risk stratification and prognostics and novel therapeutic strategies. This review details the contemporary understanding of neuroblastoma's genetic predisposition, including recent advances and discusses ongoing efforts to address gaps in our knowledge regarding this malignancy's complex genetic underpinnings. PMID- 29589101 TI - Regression of human cirrhosis: an update, 18 years after the pioneering article by Wanless et al. AB - Cirrhosis has been traditionally viewed as an irreversible, end-stage condition. Eighteen years ago, Wanless, Nakashima, and Sherman published a study that was based on the concept that hepatic architecture is under constant remodeling in the course of chronic liver diseases, even during their most advanced stages; depending on the balance between injury and repair, the histologic changes might be progressing or regressing. These authors described in detail the morphologic features of regressing cirrhosis, identified a set of histologic features of regression that they called the "hepatic repair complex," and provided convincing morphologic evidence that incomplete septal cirrhosis represents regressed cirrhosis. In the years that followed publication of this pioneering article, a number of clinical studies with performance of pre- and post-treatment liver biopsies provided abundant evidence that cirrhosis can regress after successful therapy of chronic hepatitis B, chronic hepatitis C, autoimmune hepatitis, and genetic hemochromatosis. Evidence for other chronic liver diseases may also be provided in the future, pending ongoing studies. Successful therapy allows resorption of fibrous septa, which can be followed by loss of nodularity and architectural improvement; however, many vascular lesions of cirrhotic livers are not thought to regress. Cases of cirrhosis that are considered more likely to improve than others include those of recent onset, with relatively thin fibrous septa and mild vascular changes. Histologic examination of liver biopsy specimens from patients with chronic liver diseases provides the opportunity to appreciate the features of the hepatic repair complex on a routine diagnostic basis; however, interpretation is often difficult, and can be aided by immunohistochemical stains. Clinicopathologic correlation is essential for a meaningful assessment of such cases. For many patients, cirrhosis is not an end stage condition anymore; therefore, use of the term "cirrhosis" has been challenged, almost 200 years after its invention. However, regression of cirrhosis does not imply regression of molecular changes involved in hepatocarcinogenesis; therefore, surveillance for hepatocellular carcinoma should be continued in these patients.

PMID- 29589102 TI - Dilemmas for the pathologist in the oncologic assessment of pancreatoduodenectomy specimens : An overview of different grossing approaches and the relevance of the histopathological characteristics in the oncologic assessment of pancreatoduodenectomy specimens. AB - A pancreatoduodenectomy specimen is complex, and there is much debate on how it is best approached by the pathologist. In this review, we provide an overview of topics relevant for current clinical practice in terms of gross dissection, and macro- and microscopic assessment of the pancreatoduodenectomy specimen with a suspicion of suspected pancreatic cancer. Tumor origin, tumor size, degree of differentiation, lymph node status, and resection margin status are universally accepted as prognostic for survival. However, different guidelines diverge on important issues, such as the diagnostic criteria for evaluating the completeness of resection. The macroscopic assessment of the site of origin in periampullary tumors and cystic lesions is influenced by the grossing method. Bi-sectioning of the head of the pancreas may offer an advantage in this respect, as this method allows for optimal visualization of the periampullary area. However, a head-to head comparison of the assessment of clinically relevant parameters, using axial slicing versus bi-sectioning, is not available yet and the gold standard to compare both techniques prospectively might be subject of debate. Further studies are required to validate the various dissection protocols used for pancreatoduodenectomy specimens and their specific value in the assessment of pathological parameters relevant for prognosis. PMID- 29589105 TI - Chromosome ends as adaptive beginnings: the potential role of dysfunctional telomeres in subtelomeric evolvability. AB - Telomeres serve as protective caps that help the cell differentiate between the naturally occurring ends of chromosomes and double-stranded breaks. When telomere capping function becomes compromised, chromosome ends are subjected to elevated rates of chromosome alterations. These effects can be particularly dramatic in the telomere-adjacent subtelomeric region. While the catastrophic impact of severe telomere dysfunction on genome stability has been well documented, the adaptive telomere failure hypothesis considers an alternative role telomere dysfunction may play in adaptive evolution. This hypothesis suggests that low levels of telomere failure, induced by certain environmental stresses, can lead to elevated subtelomeric recombination. Mutational loss, duplication, or modification of subtelomeric contingency genes could ultimately facilitate adaptation by generating novel mutants better able to survive environmental stress. In this perspective, we discuss recent work that examined mild telomere dysfunction and its role in altering the adaptive potential of subtelomeric genes. PMID- 29589106 TI - Macular buckle technique in myopic traction maculopathy: a 16-year review of the literature and a comparison with vitreous surgery. AB - PURPOSE: The aim of this study is to review anatomical and functional outcomes following macular buckling (MB) in high myopia and to compare such results with those obtained by pars plana vitrectomy (PPV). METHODS: PubMed articles on MB in high myopia (2000-2016) were reviewed. Main outcomes included retinal reattachment and macular hole (MH) closure rates, resolution of myopic foveoschisis (MFS), and postoperative visual acuity. RESULTS: Thirty-one articles included 16 in patients with retinal detachment due to MH (MHRD group), 11 in MFS with or without foveal detachment (MFS group), and 4 in MH patients with MFS (MH MFS group). Surgical techniques mainly differed in the type of buckle, rectus muscles involvement, and concurrent PPV. In eyes with persistent MH, prognosis in the MHRD and MH-MFS groups differed between eyes receiving MB compared to PPV: functional outcome was markedly poorer and there was a higher risk of retinal redetachment associated with PPV. In the MSF group, secondary MHs were more likely to develop in eyes treated with PPV and internal limiting membrane peeling than those undergoing MB alone or combined with PPV. Retinal pigment epithelium changes, malpositioning, perforation, and choroidal detachment were the main complications. CONCLUSIONS: Although different approaches are used, complete resolution of foveoschisis, retinal reattachment, and MH closure seem to be achieved more frequently with MB than PPV. PMID- 29589107 TI - Rhu-Epo down-regulates pro-tumorigenic activity of cancer-associated fibroblasts in multiple myeloma. AB - We have previously demonstrated that recombinant human erythropoietin (rHuEpo) is involved in the regulation of the angiogenic response in multiple myeloma (MM) through a direct effect on macrophages and endothelial cells isolated from the bone marrow of patients with MM. The aim of the present study was designed to determine the effects of rHuEpo on cancer-associated fibroblasts (CAFs) from monoclonal gammopathy of undetermined significance (MGUS) and MM patients by means of in vitro and in vivo assays. rHuEpo treatment reduces the expression of mRNA levels of fibroblast activation markers, namely alpha smooth actin (alphaSMA) and fibroblast activation protein (FAP) in MGUS and MM CAFs, and of pro-inflammatory and pro-angiogenic cytokines, including interleukin (IL)-6 and IL-8, vascular endothelial growth factor-A (VEGF-A), fibroblast growth factor-2 (FGF-2), and hepatocyte growth factor (HGF) in MM CAFs. Moreover, rHuEpo inhibits the proliferative activity of MM CAFs and increased the apoptosis of MGUS and MM CAFs. Overall, these data suggest that rHu-Epo down-regulates CAFs pro tumorigenic activity. Moreover, these results are not suggestive for a pro angiogenic activity of rHuEpo on CAFs. In fact, rHuEpo pre-treatment induces a low angiogenic response in vivo in the chorioallantoic membrane (CAM) assay of MGUS and MM CAFs conditioned medium, not comparable to that of a well-known angiogenic cytokine, VEGF-A, tested in the same assay. PMID- 29589109 TI - Prevalence and associated factors of preoperative functional disability in elective surgical patients over 55 years old: a prospective cohort study. AB - PURPOSE: In preoperative settings, patients may have functional disabilities due to the disease for which surgery is being performed or comorbidities, but the associated and predictive factors remain unknown. This study examined the prevalence of preoperative functional disability and clarified the associated factors. METHODS: Individuals aged >= 55 years who were scheduled to undergo surgery in a tertiary-care hospital in Japan between April 2016 and September 2016 were eligible for enrolment in the study. Patients with the diseases requiring psychiatric treatment and patients unable to complete the questionnaire without help were excluded. After obtaining informed consent, each patient was asked to complete the 12-item World Health Organization Disability Assessment Schedule-2.0, which is a standardized evaluation tool for assessing comprehensive living function. Data from these questionnaires and the patients' characteristics were evaluated. Multiple logistic regression analysis was conducted to determine independent factors associated with preoperative functional disability. RESULTS: Of 1201 recruited patients, 912 (75.9%) were included in our analysis. The prevalence of preoperative functional disability was 29.2%. Regression analysis identified six independent associated factors for preoperative functional disability: body mass index >= 30 kg m-2, mixed lung disease, serum albumin values, malnutrition, risk of malnutrition, and preoperative use of corticosteroids. CONCLUSIONS: In total, 29.2% of preoperative patients had functional disability. Obesity, nutritional deficiency, respiratory complications, and low serum albumin values were determined as potentially modifiable factors. PMID- 29589108 TI - Chronic diarrhoea following surgery for colon cancer-frequency, causes and treatment options. AB - PURPOSE: The growing population of survivors after colon cancer warrants increased attention to the long-term outcome of surgical treatment. The change in bowel anatomy after resection disrupts normal gastrointestinal function and may cause symptoms. Thus, many patients surviving colon cancer have to cope with bowel dysfunction for the rest of their lives. We here aim to provide an overview of the literature on this topic. METHODS: We review long-term functional outcomes of surgical treatment for colon cancer, the underlying pathology, and treatment options. RESULTS: Common symptoms include constipation, urge for defecation and diarrhoea. Causes of diarrhoea after colon cancer surgery are sparsely studied, but they probably include bile acid malabsorption, small intestinal bacterial overgrowth and disruption of the ileal brake. Specific diagnosis should be made to allow individual treatment based on the underlying pathology. Studies on treatment of functional problems after surgery for colon cancer are extremely few, but some lessons can be drawn from the treatment of other patient groups having undergone colon surgery. CONCLUSION: Diarrhoea is likely a common long term complication after colon cancer surgery. Attention to this complication and a specific diagnosis will aid the targeted treatment of patients suffering from this complication. PMID- 29589110 TI - Protein-bounded uremic toxin p-cresylsulfate induces vascular permeability alternations. AB - The goal of the present studies is to investigate that the impact of p cresylsulfate (PCS) on the endothelial barrier integrity via in situ exposure and systemic exposure. Vascular permeability changes induced by local injection of PCS were evaluated by the techniques of both Evans blue (EB) and India ink tracer. Rats were intravenously injected with EB or India ink followed by intradermal injections of various doses of PCS (0, 0.4, 2, 10 and 50 umol/site) on rat back skins. At different time points, skin EB was extracted and quantified. The administration of India ink was used to demonstrate leaky microvessels. Skin PCS levels were also determined by liquid chromatography-mass spectrometry. We also investigated whether the increased endothelial leakage occurred in the aortic endothelium in rats treated with 5/6 nephrectomy and intraperitoneal injection of PCS 50 mg/kg/day for 4 weeks. The aortic endothelial integrity was evaluated by increased immunoglobulin G (IgG) leakage. High doses of PCS, but not lower doses, significantly induced vascular leakage as compared to saline injection and EB leakage exhibited in time-dependent manner. A time correlated increase in leaky microvessels was detected in the tissues examined. The injected PCS declined with time and displayed an inverse relationship with vascular leakage. Chronic kidney disease (CKD) rats administered with PCS, compared to control rats, had significantly higher serum levels of PCS and apparent IgG deposition in the aortic intima. Increased endothelial leakage induced by PCS in skin microvessels and the aorta of CKD rats suggests that the PCS-induced endothelial barrier dysfunction. PMID- 29589111 TI - Effects of resistance training on MRI-derived epicardial fat volume and arterial stiffness in women with obesity: a randomized pilot study. AB - AIM: To date, few studies have analyzed the effects of exercise on cardiac adipose tissue. Overall, exercise programs did not meet the recommendations for significant weight loss, the utilization of resistance training was minimal, and the conclusions derived from these studies have diminished exercise as a strategy for cardiac fat loss. PURPOSE: The objective of this pilot study was to analyze the effects of 3-week high-intensity, moderate-volume muscular endurance resistance training (RT) on cardiac fat and arterial stiffness. METHODS: A total of 11 young females with obesity, BMI = 34.13 (+/- 3.16) kg/m2 (n = 5 control, n = 6 intervention) completed the study. Absolute strength was assessed using one repetition maximum test (1RM) for bench press (BP) and leg press (LP), and relative strength was calculated using body weight (BW) as BP-to-BW and LP-to-BW ratio. Magnetic resonance was used to quantify epicardial and paracardial adipose tissue (EAT and PAT) volume, and applanation tonometry was used to assess arterial stiffness by estimating pulse wave velocity (PWV). RESULTS: EAT and PAT volumes (ml) showed significant interaction effects (p = 0.037 and p = 0.031), and very large changes (d > 1) of EAT (p = 0.006) and PAT (p = 0.036) in the intervention group. In addition, strength was significantly improved, including BP (p = 0.003), LP (p = 0.001), BP-to-BW ratio (p = 0.001), and LP-to-BW ratio (p = 0.002), while no changes were found in PWV. CONCLUSIONS: High-intensity, moderate-volume RT, designed to enhance muscular endurance following the recommendations reduces EAT and PAT volumes, improves physical fitness in females with obesity, and has no negative effects on arterial stiffness. PMID- 29589112 TI - Complications following ultrasound-guided core needle biopsy of thyroid nodules: a systematic review and meta-analysis. AB - OBJECTIVES: To identify the complication rate associated with US-guided core needle biopsy (CNB) of thyroid lesions using a systematic review and meta analysis. METHODS: Ovid-MEDLINE and EMBASE databases were searched for studies on US-guided CNB of thyroid lesions from 1 January 1994-13 December 2016. A review of 393 potential papers identified 39 eligible papers including 14,818 patients. The pooled proportions of complications were assessed using random-effects modelling. Subgroup analysis was performed. Among-study heterogeneity was explored using chi2 statistic for pooled estimates and inconsistency index I2. Quality of the studies was evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies. RESULTS: The pooled proportion of overall complications after CNB of thyroid lesions was 1.11% (95% CI: 0.64-1.51, I2: 87.2%). The pooled proportion of major complications (0.06% [95% CI: 0.02-0.10], I2: 0.0%) was much lower than that of minor complications (1.08%[95% CI: 0.63-1.53], I2: 93.17%). Subgroup analysis revealed no significant differences between studies on Asian versus non-Asian groups (p=0.7769), radiologist versus non-radiologist groups (p=0.8607), nodule size <20 mm versus nodule size >=20 mm (p=0.1591) groups, CNB versus CNB-plus-FNA groups (p=0.9281) and studies performed before and after 2012 (p=0.6251). The overall quality of the included studies was moderate with all of the studies satisfying five or more of the eight total domains. CONCLUSION: Various complications can occur after US-guided CNB of thyroid lesions. However, the procedure is safe, with a low complication rate. KEY POINTS: * Various complications occurred after CNB of thyroid lesions, but the pooled complication rate was low (1.11%, I 2 = 87.2%). * The pooled proportion of major complications (0.06%) was much lower than that of minor complications (1.08%). * There was no significant differences between studies on Asian vs. non-Asian groups, radiologist vs. non-radiologist groups, nodule size <20 mm vs. nodule size >=20 mm groups, CNB vs. CNB-plus-FNA groups, or studies performed before 2012 vs. after 2012. PMID- 29589113 TI - Corticosterone level and central dopaminergic activity involved in agile and exploratory behaviours in formosan wood mice (Apodemus semotus). AB - The native Formosan wood mouse (Apodemus semotus) is the dominant rodent in Taiwan. In their natural environment, Formosan wood mice exhibit high locomotor activity, including searching and exploratory behaviours, which is observed similarly in the laboratory environment. How the behavioural responses of Formosan wood mice exhibit in elevated plus maze and marble burying tests remains unclear. How corticosterone levels and central dopaminergic activities are related to the behaviours in these tests is also unclear. This study compared the behaviours of Formosan wood mice with that of C57BL/6J mice using the elevated plus maze and marble burying tests, and measured the corticosterone levels and central dopaminergic activities. Formosan wood mice showed greater locomotor and exploratory activity than the C57BL/6J mice. Similarly, the marble burying and rearing numbers were higher for Formosan wood mice. High locomotor and exploratory behaviours were strongly correlated with corticosterone levels after acute mild restraint stress in Formosan wood mice. The anxiolytic, diazepam, reduced the high exploratory activity, corticosterone levels and central dopaminergic activities. The high locomotor and exploratory behaviours of Formosan wood mice are related to the corticosterone levels and central dopaminergic activities. These data may explain Formosan wood mice dominance in the intermediate altitude of Taiwan. PMID- 29589114 TI - Can neck pain be an initial symptom of rheumatoid arthritis? A case report and literature review. AB - Although rheumatoid arthritis (RA) is most commonly associated with peripheral joints, cervical spine involvement can be seen in almost 80% of patients in the presence of long-term disease, joint erosion, and risk factors such as male sex and rheumatoid factor positivity. It is very rare to have cervical involvement in the initial period of RA. If a patient has isolated cervical spine involvement without peripheral arthritis, it is highly likely that inappropriate investigations and delayed treatment may occur. Any damage that occurs in cervical spine may cause symptoms varying from slight instability to atlantoaxial subluxation, spinal cord and brain stem compression and even death. Therefore, physician should be aware that there may be isolated cervical involvement, albeit rare, in patients with RA. In this report, we presented a case of RA presenting with cervical spine involvement without peripheral arthritis to underline the importance of this kind of involvement in clinical practice. We also briefly reviewed other cases similar to ours in light of literature. PMID- 29589115 TI - Alternative Laparoscopic Intracorporeal Pringle Maneuver by Huang's Loop. AB - AIM: This paper aims to describe an intracorporeal tourniquet method for laparoscopic Pringle maneuver (PM). METHODS: One shortened Foley tube with side hole on the tip was put into the abdomen. Then, the tail was pulled out through the side-hole to make a loop to encircle porta hepatis for inflow control. RESULT: It is easy to keep the tension by a metallic clip, and when released, the clip can be removed and the loop loosened. CONCLUSION: Therefore, PM could be performed inside the abdomen without special instrument nor extra trocar port. The intracorporeal Pringle maneuver with Huang's loop could be routinely used during laparoscopic liver resection even for a laparoscopic beginner because it is so easily learnt, safe, and effective. PMID- 29589116 TI - Early Closure of Defunctioning Loop Ileostomy: Is It Beneficial for the Patient? A Meta-analysis. AB - OBJECTIVE: To perform a meta-analysis to answer the question, whether early closure (EC) of defunctioning loop ileostomy may be beneficial for patient as compared with late closure (LC) without exceeding the risk of surgical-related morbidity. DESIGN: Medline and the Cochrane Trials Register were searched for trials published up to November 2016 comparing EC (defined as <=14 days from the index operation in which the ileostomy was performed) versus LC for stoma closure after rectal surgery. Meta-analysis was performed using Review Manager 5.0. Inclusion criteria MAIN OUTCOME MEASURES: Overall morbidity rate, anastomotic leakage rate, and wound infection rate within 90 days after elective surgery. RESULTS: Six studies were included and analyzed, yielding 570 patients (252 in EC group and 318 in LC). Meta-analysis showed no significant difference in the overall morbidity rate between the EC and LC groups (OR 0.63; 95% CI, 0.22-1.78; P = 0.38). Despite a significant higher wound infection rate of stoma site (OR 3.83; 95% CI 2.14-6.86; P < 0.00001), meta-analysis showed no significant difference in the anastomotic leakage rate between the EC and LC groups (OR 0.63; 95% CI 0.22-1.78; P = 0.38). Moreover, both stoma-related complications (OR 0.46; 95% CI 0.24-0.86; P = 0.02) and small bowel obstruction rates (OR 0.11; 95% CI 0.06-0.20; P < 0.00001) were significantly lower in the EC group than in the LC group, respectively. LIMITATIONS: Heterogeneity of the studies CONCLUSION: This meta-analysis suggests that EC of a defunctioning loop ileostomy is effective and safe in careful selected patients without increasing overall postoperative complications. This promising strategy should be proposed in patients in order to reduce stoma-related complications. PMID- 29589117 TI - The degenerin region of the human bile acid-sensitive ion channel (BASIC) is involved in channel inhibition by calcium and activation by bile acids. AB - The bile acid-sensitive ion channel (BASIC) is a member of the ENaC/degenerin family of ion channels. It is activated by bile acids and inhibited by extracellular Ca2+. The aim of this study was to explore the molecular mechanisms mediating these effects. The modulation of BASIC function by extracellular Ca2+ and tauro-deoxycholic acid (t-DCA) was studied in Xenopus laevis oocytes heterologously expressing human BASIC using the two-electrode voltage-clamp and outside-out patch-clamp techniques. Substitution of aspartate D444 to alanine or cysteine in the degenerin region of BASIC, a region known to be critically involved in channel gating, resulted in a substantial reduction of BASIC Ca2+ sensitivity. Moreover, mutating D444 or the neighboring alanine (A443) to cysteine significantly reduced the t-DCA-mediated BASIC stimulation. A combined molecular docking/simulation approach demonstrated that t-DCA may temporarily form hydrogen bonds with several amino acid residues including D444 in the outer vestibule of the BASIC pore or in the inter-subunit space. By these interactions, t-DCA may stabilize the open state of the channel. Indeed, single-channel recordings provided evidence that t-DCA activates BASIC by stabilizing the open state of the channel, whereas extracellular Ca2+ inhibits BASIC by stabilizing its closed state. In conclusion, our results highlight the potential role of the degenerin region as a critical regulatory site involved in the functional interaction of Ca2+ and t-DCA with BASIC.

Consequently, a high diversity of tick transmitted pathogens might be a potential threat to humans. However, only a limited number of tick species regularly infest humans, and pathogens present in such species are therefore of particular interest from a medical perspective. In this study, 297 ticks were collected from humans during 2013 and 2014. Ixodes ricinus was the predominant tick species, accounting for 272 specimens or 91.6% of the ticks in the study. Nevertheless, other tick species were also found to infest humans: Dermacentor marginatus constituted 7% of the ticks found on humans (21/297), Haemaphysalis punctata 1% (3/297), and Haemaphysalis concinna 0.3% (1/297). Ticks were tested by PCR for a wide range of tick-borne pathogens. In total, 11.8% of the ticks carried human pathogenic bacteria, while no viral or protozoan pathogens were detected. The most frequently detected pathogen was Rickettsia spp., occurring in 5.4% of the ticks (16/297) and comprising three species: Rickettsia (R.) raoultii, R. monacensis, and R. helvetica. Borrelia s.l. occurred in 3% (9/297) of the ticks. "Candidatus Neoehrlichia mikurensis" occurred in 1.7% (5/297) and Anaplasma phagocytophilum in 1.3% (4/297). Anaplasma bovis was detected in an H. punctata and Borrelia miyamotoi in an I. ricinus. These results point to the need for further studies on the medical importance of tick-borne pathogens in Romania.

AB - PROPOSAL: The aim of this study was to examine the association between the consumption of total and specific types of dairy products and the risk of incident cataracts in an elderly Mediterranean population at high cardiovascular risk. METHODS: We prospectively analyzed 5860 subjects from the PREvencion con DIeta MEDiterranea (PREDIMED) Study. The time to cataract surgery was calculated as the time between recruitment and the date of the surgery, last visit of the follow-up, date of death, or until the end of the study. Dairy products intake was assessed using validated food frequency questionnaires. We used Cox proportional hazard regression to assess the risk of cataract surgery according to average dietary energy-adjusted total dairy products, milk, yogurt and cheese consumption. RESULTS: We documented a total of 768 new cataract events after a median of 5.6 years of follow-up. Subjects in the second [hazard ratio (HR) 0.62; 95% CI 0.52, 0.74] and third tertile (HR: 0.71; 95% CI 0.60, 0.85) of skimmed yogurt intake had a significantly lower risk of cataracts after adjusting for potential confounders. No significant associations were observed for total dairy products, whole and skimmed milk, whole yogurt and cheese consumption. CONCLUSION: The intake of skimmed yogurt was associated with a reduced risk of cataracts in an elderly Mediterranean population with high cardiovascular risk. No significant associations were observed for other type of dairy product. CLINICAL TRIAL REGISTRATION: International Standard Randomized Controlled Trial Number (ISRCTN): 35739639.

AB - Since the early days of modern neuroscience, psychological models of brain function have been a key component in the development of new knowledge. These models aim to provide a framework that allows the integration of discoveries derived from the fundamental disciplines of neuroscience, including anatomy and physiology, as well as clinical neurology and psychiatry. During the initial stages of his career, Sigmund Freud (1856-1939), became actively involved in these nascent fields with a burgeoning interest in functional neuroanatomy. In contrast to his contemporaries, Freud was convinced that cognition could not be localised to separate modules and that the brain processes cognition not in a merely serial manner but in a parallel and dynamic fashion-anticipating fundamental aspects of current network theories of brain function. This article aims to shed light on Freud's seminal, yet oft-overlooked, early work on functional neuroanatomy and his reasons for finally abandoning the conventional neuroscientific "brain-based" reference frame in order to conceptualise the mind from a purely psychological perspective. PMID- 29589122 TI - Simultaneous determination of estrone and selected pesticides in water medium by GC-MS after multivariate optimization of microextraction strategy. AB - A sensitive and accurate analytical method based on dispersive liquid-liquid microextraction was developed for the simultaneous determination of selected pesticides, hormones, and endocrine disruptors by GC-MS. The optimum conditions of the extraction procedure were determined using an experimental design of factors significantly affecting the extraction output. Analysis of variance (ANOVA) was used to evaluate the main effects of experimental factors and their interactions. The limit of detection values determined for the analytes under optimum experimental conditions were found to be between 0.30-2.0 ng/mL. The linear calibration plot of analytes span across a wide concentration range and low %RSD values from replicate measurements indicated good precision of the developed method. Spiked recovery tests were also performed on municipal wastewater, well water, lake water, sea water, and tap water matrices to determine the method's accuracy and applicability to water samples. The recovery results obtained were satisfactory for all water samples.

AB - Several detailed studies of the external morphology of the ear region in extinct sloths have been published in the past few decades, and this anatomical region has proved extremely helpful in elucidating the phylogenetic relationships among the members of this mammalian clade. Few studies of the inner ear anatomy in these peculiar animals were conducted historically, but these are increasing in number in recent years, in both the extinct and extant representatives, due to wider access to CT-scanning facilities, which allow non-destructive access to internal morphologies. In the present study, we analyze the extinct ground sloth Glossotherium robustum and provide a description of the external features of the ear region and the endocranial side of the petrosal bone, coupled with the first data on the anatomy of the bony labyrinth. Some features observable in the ear region of G. robustum (e.g., the shape and size of the entotympanic bone and the morphology of the posteromedial surface of the petrosal) are highly variable, both intraspecifically and intraindividually. The form of the bony labyrinth of G. robustum is also described, providing the first data from this anatomical region for the family Mylodontidae. The anatomy of the bony labyrinth of the genus Glossotherium is here compared at the level of the superorder Xenarthra, including all available extant and extinct representatives, using geometric morphometric methods. In light of the new data, we discuss the evolution of inner ear anatomy in the xenarthran clade, and most particularly in sloths, considering the influence of phylogeny, allometry, and physiology on the shape of this highly informative region of the skull. These analyses show that the inner ear of Glossotherium more closely resembles that of the extant anteaters, and to a lesser extent those of the giant ground sloth Megatherium and euphractine armadillos, than those of the extant sloths Bradypus and Choloepus, further demonstrating the striking morphological convergence between the two extant sloth genera.

AB - Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67 degrees N, compared to regions further south along the Norwegian coast, with no clear understanding why. In order to study a similar organism in the same ecosystem, the present study analyzed 210 shore crabs (Carcinus maenas) from four different locations along the Norwegian coast, two in the North and two in the South. The physiological variables size, sex, molting stage, hepatosomatic index, carapace color, and gonad maturation were registered, in attempt to explain the high inter-individual variation in cadmium levels in hepatopancreas. In contrast to the brown crabs, the shore crabs showed no clear geographical differences in cadmium concentrations. This indicates physiological differences between the two crab species. No clear and consistent correlations were found between cadmium levels and physiological parameters, except for sex, where cadmium concentration in hepatopancreas was twice as high in males compared to females. The cadmium levels also varied with season, with approximately 40 and 60% lower cadmium concentration in April than August for male and female shore crabs, respectively. None of the analyzed cadmium concentrations in muscle meat from claws exceeded EUs food safety limit, and low cadmium levels in soup prepared from shore crabs clearly indicated that this dish is not problematic regarding food safety. PMID- 29589124 TI - Biotechnological approaches for artemisinin production in Artemisia. AB - Artemisinin and its analogues are naturally occurring most effective antimalarial secondary metabolites. These compounds also possess activity against various types of cancer cells, schistosomiasis, and some viral diseases. Artemisinin and its derivatives (A&D) are found in very low amounts in the only natural source i.e. Artemisia plant. To meet the global needs, plant sources have been exploited for the enhanced production of these natural products because their chemical synthesis is not profitable. The generally adopted approaches include non transgenic (tissue and cell cultures) and transgenic together with the cell, tissue, and whole transgenic plant cultures. The genes targeted for the overproduction of A&D include the biosynthetic pathway genes, trichome development genes and rol genes, etc. Artemisinin is naturally produced in trichomes of leaves. At the same time, transgenic hairy roots are considered a good source to harvest artemisinin. However, the absence of trichomes in hairy roots suggests that artemisinin biosynthesis is not limited to trichomes. Moreover, the expression of the gene involved in trichome development and sesquiterpenoid biosynthesis (TFAR1) in transgenic and non-transgenic roots provokes researchers to look for new insight of artemisinin biosynthesis. Here we discuss and review precisely the various biotechnological approaches for the enhanced biosynthesis of A&D. PMID- 29589126 TI - Competitive sorption of Ni and Zn at the aluminum oxide/water interface: an XAFS study. AB - Trace metals (e.g. Ni, Zn) leached from industrial and agricultural processes are often simultaneously present in contaminated soils and sediments. Their mobility, bioavailability, and ecotoxicity are affected by sorption and cosorption at mineral/solution interfaces. Cosorption of trace metals has been investigated at the macroscopic level, but there is not a clear understanding of the molecular scale cosorption processes due to lack of spectroscopic information. In this study, Ni and Zn cosorption to aluminum oxides (gamma-Al2O3) in binary-sorbate systems were compared to their sorption in single-sorbate systems as a function of pH using both macroscopic batch experiments and synchrotron-based X-ray absorption fine structure spectroscopy. At pH 6.0, Ni and Zn were sorbed as inner sphere surface complexes and competed for the limited number of reactive sites on gamma-Al2O3. In binary-sorbate systems, Ni had no effect on Zn sorption, owning to its lower affinity for the metal oxide surface. In contrast, Zn had a higher affinity for the metal oxide surface and reduced Ni sorption. At pH 7.5, Ni and Zn were sorbed as mixed-metal surface precipitates, including Ni-Al layered double hydroxides (LDHs), Zn-Al LDHs, and likely Ni-Zn-Al layered triple/ternary hydroxides. Additionally, at pH 7.5, Ni and Zn do not exhibit competitive sorption effects in the binary system. Taken together, these results indicated that pH critically influenced the reaction products, and provides a crucial scientific basis to understand the potential mobility, bioavailability, and ecotoxicity of Ni and Zn in natural and contaminated geochemical environments. PMID- 29589127 TI - Launching Anxious Young Adults: A Specialized Cognitive-Behavioral Intervention for Transitional Aged Youth. AB - PURPOSE OF REVIEW: There has been growing clinical and research attention to the unique developmental stage of emerging adulthood. This stage is a time of significant change and growth for all individuals, as it includes identity exploration, emotional, behavioral, and financial independence from caregivers, and completion of educational or vocational requirements. RECENT FINDINGS: Anxiety disorders are the most common mental health diagnoses among emerging adults, and individuals suffering from these disorders often experience compounding functional impairments across health, financial, and social domains. While evidence-based treatments exist for both child/adolescent anxiety disorders and adult anxiety disorders, no specialized assessment or treatment methods have been established for the unique period of emerging adulthood. Our review examines literature pertinent to anxiety disorders in emerging adulthood and describes a novel, specialized intervention to address the unique challenges faced by anxious emerging adults. The Launching Emerging Adults Program (LEAP) is a developmentally informed cognitive-behavioral treatment model that aims to simultaneously reduce anxiety symptoms and promote independence. We conclude with a discussion of lessons learned and future directions. PMID- 29589128 TI - Photoconductivity, pH Sensitivity, Noise, and Channel Length Effects in Si Nanowire FET Sensors. AB - Silicon nanowire (NW) field-effect transistor (FET) sensors of various lengths were fabricated. Transport properties of Si NW FET sensors were investigated involving noise spectroscopy and current-voltage (I-V) characterization. The static I-V dependencies demonstrate the high quality of fabricated silicon FETs without leakage current. Transport and noise properties of NW FET structures were investigated under different light illumination conditions, as well as in sensor configuration in an aqueous solution with different pH values. Furthermore, we studied channel length effects on the photoconductivity, noise, and pH sensitivity. The magnitude of the channel current is approximately inversely proportional to the length of the current channel, and the pH sensitivity increases with the increase of channel length approaching the Nernst limit value of 59.5 mV/pH. We demonstrate that dominant 1/f-noise can be screened by the generation-recombination plateau at certain pH of the solution or external optical excitation. The characteristic frequency of the generation-recombination noise component decreases with increasing of illumination power. Moreover, it is shown that the measured value of the slope of 1/f-noise spectral density dependence on the current channel length is 2.7 which is close to the theoretically predicted value of 3.

AB - PURPOSE OF REVIEW: This study aims to provide a review of the randomized controlled studies evaluating the effects of shared decision-making (SDM) intervention in comparison to care as usual in patients with mood disorders. RECENT FINDINGS: Of the 14 randomized controlled studies identified, only three 6 month studies evaluated the interest of SDM interventions using decision aids in depressed patients. All of them showed that the intervention effectively improved patient satisfaction and engagement in the decision-making process. Only one study in patients with bipolar disorder (BD) showed improvement of depressive symptoms, functioning, and quality of life. Other included studies were collaborative care interventions using a SDM approach in patients with depression in specific populations depending on age, gender, income, and physical comorbidities. All of them showed significant improvement in depression outcomes or medication adherence. SDM interventions using decision aids and collaborative care showed evidence of improvements in the management of depression. Stronger evidence of SDM interest in BD is needed. PMID- 29589130 TI - The tension of framed membranes from computer simulations. AB - We have analyzed the behavior of a randomly triangulated, self-avoiding surface model of a flexible, fluid membrane subject to a circular boundary by Wang-Landau Monte Carlo computer simulation techniques. The dependence of the canonical free energy and frame tension on the frame area is obtained for flexible membranes. It is shown that for low bending rigidities the framed membrane is only stable above a threshold tension, suggesting a discontinuous transition from the collapsed (branched polymer) state to a finite tension extended state. In a tension range above this threshold tension the membranes display power-law characteristics for the equation of state, while higher tension levels includes both an extended linear (elastic) as well as a highly non-linear stretching regime. For semi flexible membranes a transition from extended to buckled conformations takes place at negative frame tensions. Our analysis indicates that at zero frame tension the crumpling transition of fluid membranes show characteristics of both critical behavior and a discontinuous transition at low bending rigidities. PMID- 29589131 TI - Recent Progress in Pharmacogenomics of Antipsychotic Drug Response. AB - PURPOSE OF REVIEW: Pharmacogenomics (PGx) of antipsychotic drug response is an active area of research in the past few years. We reviewed recent PGx studies with an emphasis of development of new methodologies and new research directions. RECENT FINDINGS: Traditional candidate gene approach continues to generate evidence to support the associations of antipsychotic response with genes coding for drug targets such as DRD2. Genome-wide association studies have found a few novel genes that may be associated with drug efficacy and adverse events. Recent application of polygenic risk score makes it possible to combine many genetic variants to predict clinical response. Finally, epigenetic research including DNA methylation is emerging and promises new findings that potentially can be applied in clinical practice. New methodologies may advance PGx closer to clinical application. Multiple genes and epigenomic markers can be used in prediction of clinical phenotypes. PMID- 29589133 TI - Knowledge of smoking as a risk factor for disease among urology clinic patients in Australia. AB - INTRODUCTION: Smoking remains a common habit among the general population. Despite the well-established risks of smoking, relatively few studies have been undertaken to assess the understanding of these risks among the general population. We intended to assess the understanding of smoking as a risk factor for various conditions in a urology outpatient cohort to assess the level of knowledge as well as particular strengths and weaknesses they possess. METHODS: A four-page questionnaire was distributed among urology outpatients over a 5 month period. The questionnaire captured information regarding the knowledge of smoking as a risk factor for various urological and non-urological conditions. Results were collated and stratified according to patient's cancer history as well as smoking status. RESULTS: A total of 112 participants were included in our analytical sample. Our study demonstrated a deficiency in knowledge regarding smoking and urological conditions. When ranked by level of knowledge, four of the bottom five conditions were urological in nature. Furthermore, we found that patients with a personal cancer history demonstrated generally poorer knowledge of smoking as a risk factor compared to patients without a cancer history. Conversely, smokers themselves demonstrated a greater understanding of risks compared to non-smokers. CONCLUSIONS: Our study suggests there is much work to be done in the education of patients on the risks of smoking from a urological point of view. We believe more initiative needs to be taken by the specialists treating such patients to achieve an improved level of knowledge. PMID- 29589132 TI - Smoking quantity determines disease activity and function in Chinese patients with ankylosing spondylitis. AB - The objective of this study was to systemically and comprehensively evaluate the associations between smoking and disease outcomes in patients with ankylosing spondylitis (AS). Information on smoking, clinical features, and sociodemographic characteristics was collected by a questionnaire administered directly to the patient. Group differences were analyzed by t test or chi-square test. Logistic regression analysis was conducted with the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), C-reactive protein, and erythrocyte sedimentation rate as the dependent variables and different stratification of smoking duration, smoking intensity, and cumulative smoking as independent variables. In order to compare our results with previous studies, meta-analysis was performed to calculate standardized mean difference (SMD) for relationship between outcomes and smoking status. A total of 1178 AS patients were analyzed. Compared with non-smokers, the risk of having active disease (BASDAI >= 4) was higher in patients who smoked at least 15 years, or 15 cigarettes per day, or 15 pack-years (OR = 1.70 [1.06, 2.73], 1.75 [1.08, 2.82], and 1.97 [1.06, 3.67], respectively); and smokers had increasing risk of BASDAI >= 4 with increasing years of smoking, or cigarettes per day, or pack-years (p-trend = 0.010, 0.008 and 0.006, respectively). The risk of having active disease was higher in patients who smoked at least 15 cigarettes per day or 15 pack-years (OR = 1.74 [1.06, 2.84] and 2.89 [1.56, 5.35], respectively), with increasing number of cigarettes per day and pack-years. Smokers had an increased risk of BASFI >= 4 (p trend = 0.040 and 0.007, respectively). By meta-analysis, current, former and ever smokers had significantly higher BASDAI (SMD = 0.34 [0.18, 0.48], 0.10 [0.01, 0.19], and 0.27 [0.20, 0.34], respectively) and BASFI (SMD = 0.35 [0.16, 0.55], 0.30 [0.22, 0.39], and 0.35 [0.21, 0.50], respectively) compared to non smokers. Smoking is a risk factor for greater disease activity and worse functioning in AS patients. PMID- 29589134 TI - The relationship between HPV status and chemoradiotherapy in the locoregional control of penile cancer. AB - BACKGROUND: Penile cancer (PeCa) is a rare, aggressive malignancy often associated with the human papillomavirus (HPV). The practice of a personalized risk-adapted approach is not yet established. This study is to assess the relationship between HPV tumor status and chemoradiotherapy (CRT) in PeCa locoregional control (LRC). METHODS: We retrospectively identified patients with HPV status who were diagnosed with squamous cell carcinoma of the penis and treated with surgical resection between 1999 and 2016. The relationship between tumor/treatment characteristics and LRC were analyzed with univariate and multivariate Cox proportional hazard regression analysis (UVA and MVA, respectively). Time-to-event outcomes were estimated with Kaplan-Meier curves and compared via log-rank tests. RESULTS: Fifty-one patients were identified. The median follow-up was 36.6 months. Patients were primarily HPV-negative (HPV-) (n = 28, 55%), and pathologic node positive (pN+) (55%). The 2 year LRC rate was 54%. pN+ patients had a significantly lower 2 year LRC (37 vs. 81%, p = 0.002). In the subgroup analysis of pN+ patients (n = 28), there was a LRC benefit associated with the addition of CRT (HR 0.19; 95% CI 0.05-0.70, p = 0.012) and HPV-positive (HPV+) disease (HR 0.18; 95% CI 0.039-0.80, p = 0.024) using MVA. HPV+ patients treated with CRT had improved 2 year LRC compared to HPV- patients (83 vs. 38%, p = 0.038). CONCLUSIONS: Adjuvant CRT and HPV+ disease independently predicted for improved LRC in pN+ PeCa. In HPV+ PeCa, the LRC benefit was primarily observed in patients treated with adjuvant CRT. Prospective investigation of HPV+ and CRT is required to further delineate their roles in optimizing PeCa treatment. PMID- 29589135 TI - Safety and effectiveness of umbilical hernia repair in patients with cirrhosis. AB - PURPOSE: Umbilical hernia is a common complication in patients with cirrhosis. Early studies have reported a high morbidity and mortality associated with hernia repair. The traditional approach has been to non-operatively manage umbilical hernias in patients with cirrhosis. There are emerging data suggesting that an elective repair is a preferable approach. This study examined the outcomes of umbilical hernia repair in patients with advanced liver disease and compared this with a control group of non-cirrhotic patients. METHODS: Prospective data were collected regarding the outcome of umbilical hernia repairs performed between 2004 and 2013 at the Austin Hospital, Melbourne, Australia. Outcomes at 90 days were compared between patients with and without cirrhosis. RESULTS: 79 patients with cirrhosis and 249 controls were analysed. Of the patients with cirrhosis, 9% were classified as Child-Pugh A, 61% were Child-Pugh B and 30% were Child-Pugh C. Emergency repairs for complicated hernias was undertaken in 18% of the cirrhosis population and 10% in controls (P = 0.10). Post-operative complications occurred more commonly in patients with cirrhosis (26%) compared with controls (11%) (P < 0.01). Emergency hernia repairs were associated with a higher complication rate in both patients with cirrhosis (62%) and controls (20%) (P = 0.01). There was no significant difference in the rate of hernia recurrence as assessed by clinical examination between patients with cirrhosis (2.7%) and controls (6.8%) (P = 0.17) nor in 90-day mortality between patients with cirrhosis (n = 1, 1.3%) and the controls (n = 0) (P = 0.43). CONCLUSIONS: Within the limitations of a small study cohort and therefore an underpowered study, elective surgical repair of umbilical hernias in patients with cirrhosis, including decompensated cirrhosis, may not be associated with a significant increase in mortality when compared to a control cohort. Whilst complications are higher in cirrhotic patients, there is no difference in the rate of hernia recurrence. Emergency repairs of umbilical hernias are associated with a high complication rate in cirrhotic patients. PMID- 29589136 TI - Syndemic Conditions, HIV Transmission Risk Behavior, and Transactional Sex Among Transgender Women. AB - This study examined the effect of four syndemic conditions-namely, polydrug use, depression, childhood sexual abuse, and intimate partner violence-on rates of HIV transmission risk behavior (TRB) and separately, transactional sex among transgender women. TRB was defined as the number of condomless penetrative sex events with a casual or main partner of discordant or unknown HIV status. Using data from 212 transgender women in New York City, multivariable analyses revealed that, compared to those with no syndemic conditions, dramatically higher rates of recent HIV TRB events (ARR = 8.84, p < 0.001) and recent transactional sex events (ARR = 8.32, p < 0.001) were reported by participants with all four syndemic conditions. These findings highlight the importance of considering the role of syndemic conditions in HIV risk among transgender women, and the need for comprehensive psychosocial interventions to improve sexual health among this population. PMID- 29589137 TI - Barriers and Facilitators to Oral PrEP Use Among Transgender Women in New York City. AB - Transgender women may face a disparate risk for HIV/AIDS compared to other groups. In 2012, Truvada was approved for daily use as HIV pre-exposure prophylaxis (PrEP). However, there is a dearth of research about barriers and facilitators to PrEP in transgender women. This paper will shed light on transgender women living in New York City's perceived and actual challenges to using PrEP and potential strategies to overcome them. After completing an initial screening process, four 90-min focus groups were completed with n = 18 transgender women. Participants were asked what they like and dislike about PrEP. Participants identified the following barriers: uncomfortable side effects, difficulty taking pills, stigma, exclusion of transgender women in advertising, and lack of research on transgender women and PrEP. Facilitators included: reducing pill size, increasing the types of available HIV prevention products, and conducting scientific studies to evaluate PrEP in transgender women. PMID- 29589138 TI - Mutational analysis of triple-negative breast cancers within the International Breast Cancer Study Group (IBCSG) Trial 22-00. AB - PURPOSE: We investigated the occurrence and the prognostic and predictive relationship of a selected number of somatic mutations in triple-negative breast cancer (TNBC) patients having known clinical outcomes treated within the IBCSG Trial 22-00. METHODS: A matched case-control sampling selected patients enrolled in the IBCSG Trial 22-00 who had TNBC tumors, based on local assessment. Cases had invasive breast cancer recurrence (at local, regional, or distant site) according to the protocol definition. Matched controls had not recurred. Mutational analysis was performed with OncoCarta panel v1.0 using Mass Array System. The panel includes 19 genes belonging to different functional pathways as PI3K pathway, receptor tyrosine kinase, and cell cycle-metabolic group. Conditional logistic regression assessed the association of mutation status with breast cancer recurrence. RESULTS: Mutation assessment was successful for 135 patients (49 cases, 86 controls). A total of 37 (27.4%) of the 135 patients had at least one mutation in the selected genes. PIK3CA was the most common mutated gene (18/135; 13.3%), followed by BRAF, KIT and PDGFRA (each 4/135, 3.0%) and AKT1 (3/135; 2.2%). TNBC patients with at least one mutation had increased odds of recurrence compared with those with wild-type tumors (odds ratio (OR) 2.28; 95% CI 0.88-5.92), though this difference was not statistically significant (p = 0.09). We found no evidence that these mutations were predictive for the value of maintenance metronomic chemotherapy. CONCLUSIONS: Mutations in the tested oncogenes were not associated with breast cancer recurrence in this TNBC subset of patients. The question of whether any of these mutated genes (e.g., PIK3CA) may represent a useful therapeutic target in TNBC may be answered by ongoing clinical trials and/or larger dataset analysis. PMID- 29589139 TI - Fish Community Structure and Diet Responses to Newbury Weirs in a Low-Gradient River. AB - Restoration projects are often implemented to address specific issues in the environment. Consequences of a restoration project, if any are measured, typically focus on direct changes to the projects focus. However, changing habitat structure likely results in changes to the environment that affect the communities living there. Rock weirs have been used for channel stabilization in many midwestern rivers. Previous research in a southern Illinois river found that weirs benefitted aquatic macroinvertebrate and riparian bird communities by enhancing habitat heterogeneity and insect emergence production. We hypothesized that fishes would also benefit from weirs through enhanced habitat and food availability. We collected fishes in the Cache River in southern Illinois using hand nets, seines, and electroshocking at sites where weirs had been installed and at non-weir sites. Gut contents were identified and individual food items measured. Fish species richness, but not diversity, was higher at weir sites. Fish communities also differed between site types, with benthic feeders characterizing weir sites. Gut content biomass and abundance differed among fish guilds but not between weir and non-weir sites. Fishes from both site types selected for prey taxa predominately found at weirs. Differences between site types were not always captured by univariate metrics, but connecting fish prey to habitat suggests a reach-scale benefit for fishes through increased abundance of favored prey and enhanced prey diversity. Additionally, given the paucity of rocky substrata in the river as a whole, rock weirs enhance fish species richness by providing habitat for less common benthic species. PMID- 29589140 TI - Systematic review of tonsil surgery quality registers and introduction of the Nordic Tonsil Surgery Register Collaboration. AB - PURPOSE: Surgical quality registers provide tools to measure and improve the outcome of surgery. International register collaboration creates an opportunity to assess and critically evaluate national practices, and increases the size of available datasets. Even though millions of yearly tonsillectomies and tonsillotomies are performed worldwide, clinical practices are variable and inconsistency of evidence regarding the best clinical practice exists. The need for quality improvement actions is evident. We aimed to systematically investigate the existing tonsil surgery quality registers found in the literature, and to provide a thorough presentation of the planned Nordic Tonsil Surgery Register Collaboration. METHODS: A systematic literature search of MEDLINE and EMBASE databases (from January 1990 to December 2016) was conducted to identify registers, databases, quality improvement programs or comprehensive audit programs addressing tonsil surgery. RESULTS: We identified two active registers and three completed audit programs focusing on tonsil surgery quality registration. Recorded variables were fairly similar, but considerable variation in coverage, number of operations included and length of time period for inclusion was discovered. CONCLUSION: Considering tonsillectomies and tonsillotomies being among the most commonly performed surgical procedures in otorhinolaryngology, it is surprising that only two active registers could be identified. We present a Nordic Tonsil Surgery Register Collaboration-an international tonsil surgery quality register project aiming to provide accurate benchmarks and enhance the quality of tonsil surgery in Denmark, Finland, Norway and Sweden.

AB - The Second International Symposium on HPV Infection in Head and Neck Cancer was held on 3rd-4th November 2016 in Leipzig, Germany. The meeting brought together researchers and clinicians to share the latest knowledge on HPV infection in head and neck cancer and to join active and constructive scientific discussions. This report summarizes the major themes discussed during the symposium. PMID- 29589144 TI - Changes in tree resistance, recovery and resilience across three successive extreme droughts in the northeast Iberian Peninsula. AB - Understanding which variables affect forest resilience to extreme drought is key to predict future dynamics under ongoing climate change. In this study, we analyzed how tree resistance, recovery and resilience to drought have changed along three consecutive droughts and how they were affected by species, tree size, plot basal area (as a proxy for competition) and climate. We focused on the three most abundant pine species in the northeast Iberian Peninsula: Pinus halepensis, P. nigra and P. sylvestris during the three most extreme droughts recorded in the period 1951-2010 (occurred in 1986, 1994, and 2005-2006). We cored trees from permanent sample plots and used dendrochronological techniques to estimate resistance (ability to maintain growth level during drought), recovery (growth increase after drought) and resilience (capacity to recover pre drought growth levels) in terms of tree stem basal area increment. Mixed-effects models were used to determine which tree- and plot-level variables were the main determinants of resistance, recovery and resilience, and to test for differences among the studied droughts. Larger trees were significantly less resistant and resilient. Plot basal area effects were only observed for resilience, with a negative impact only during the last drought. Resistance, recovery and resilience differed across the studied drought events, so that the studied populations became less resistant, less resilient and recovered worse during the last two droughts. This pattern suggests an increased vulnerability to drought after successive drought episodes. PMID- 29589143 TI - The multiplanar analysis of the retromandibular vein in surgical planning for parotid gland tumors. AB - OBJECTIVE: To analyze the effectiveness of the multiplanar analysis of the retromandibular vein in establishing the position of the parotid gland tumor and its relationship with the facial nerve, together with the most common radiological criteria (facial nerve line, Utrecht line, retromandibular vein and parapharyngeal space variations) using the magnetic resonance imaging. STUDY DESIGN: Retrospective study SETTING: Tertiary Academic Hospital SUBJECTS AND METHODS: 128 preoperative magnetic resonances were analyzed to study preoperative tumor location (medial or lateral to the expected course of the facial nerve) based on comparison between the radiological criteria and the surgical findings. RESULTS: FN line had the lowest accuracy at 77%, whereas the retromandibular vein achieved 85% accuracy and the UT line achieved accuracy of 93%. The retromandibular vein could not be identified in 11 cases (9%). The multiplanar evaluation of the retromandibular vein allowed us to identify it on almost all MR images (99% of cases) and reach 87% of accuracy. The parapharyngeal space evaluation achieved 92% of accuracy. In the subgroup of 66 cases where the neoplasms were strictly related to the main trunk, where the surgery entailed manipulation if situated laterally to the tumor, the multiplanar evaluation of the retromandibular vein reached 98% of accuracy and UT line achieved 94%. CONCLUSIONS: The multiplanar modality, combined with the evaluation of the parapharyngeal space, is effective in helping the surgeon to achieve accurate planning: it enables the tumor to be located and the facial nerve course predicted with a good precision. PMID- 29589142 TI - Prognostic values of hematological biomarkers in nasopharyngeal carcinoma patients treated with intensity-modulated radiotherapy. AB - PURPOSE: In this study, we evaluated the prognostic values of hematological biomarkers in primary nasopharyngeal carcinoma (NPC) patients receiving definitive intensity-modulated radiotherapy (IMRT). METHODS: There were 427 NPC patients enrolled between January 2010 and March 2013 at Fudan University Shanghai Cancer Center. Pre-treatment absolute neutrophil count (ANC), platelet count (APC), lymphocyte count (ALC), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were collected as prognostic biomarkers. The Kaplan-Meier method and log-rank test were utilized to calculate progression-free survival (PFS) and overall survival (OS). The Cox proportional hazard models were applied to assess variables. RESULTS: ANC, APC and ALC were declined, while NLR and PLR were elevated significantly after therapy (P < 0.001 each). On multivariate analysis, pre-treatment NLR >= 2.32 was associated with shortened OS (P = 0.048) and PFS (P = 0.008), whereas PLR >= 123.0 was related with inferior OS (P = 0.032), yet it was not correlated with PFS (P = 0.161). CONCLUSIONS: High pre-treatment NLR and PLR indicated poor survival in NPC patients treated with IMRT-based therapy. As easily accessible and economically feasible biomarkers, NLR and PLR can be applied into clinical practice, in combination with current TNM staging, to design a more personalized treatment in these patients. PMID- 29589145 TI - Anatomical description of the umbilical arteries and impact of their ligation on pelvic and perineal vascular supply after cystectomy in women. AB - OBJECTIVE: In radical cystectomy, the surgeon generally ligates the umbilical artery at its origin. This artery may give rise to several arteries that supply the sexual organs. Our aim was to evaluate pelvic and perineal devascularisation in women after total cystectomy. PATIENTS AND METHODS: We carried out a prospective anatomical and radiological study. We performed bilateral pelvic dissections of fresh adult female cadavers to identify the dividing branches of the umbilical artery. In parallel, we examined and compared the pre- and postoperative imaging investigations [magnetic resonance imaging (MRI) angiography] in patients undergoing cystectomy for benign disease to quantify the loss of pelvic vascularisation on the postoperative images by identifying the occluded arteries. RESULTS: The anatomical study together with the radiological study visualised 35 umbilical arteries (n = 70) with their branching patterns and collateral arteries. The uterine artery originated from the umbilical artery in more than 75% of cases (n = 54) of the internal pudendal artery in 34% (n = 24) and the vaginal artery in 43% (n = 30). The postoperative MRI angiograms showed pelvic devascularisation in four patients. Devascularisation was dependent on the level of surgical ligation. In the four patients with loss of pelvic vascular supply, the umbilical artery had been ligated at its origin. CONCLUSION: The umbilical artery gives rise to various branches that supply the pelvis and perineum. If the surgeon ligates the umbilical artery at its origin during total cystectomy, there is a significant risk of pelvic and perineal devascularisation. PMID- 29589146 TI - Ectopic expression of VpSTS29, a stilbene synthase gene from Vitis pseudoreticulata, indicates STS presence in cytosolic oil bodies. AB - MAIN CONCLUSION: Stilbene synthase (STS) and its metabolic products are accumulated in senescing grapevine leaves. Ectopic expression of VpSTS29 in Arabidopsis shows the presence of VpSTS29 in oil bodies and increases trans piceid in developing leaves. Stilbenes are the natural antimicrobial phytoalexins that are synthesised via the phenylpropanoid pathway. STS is the key enzyme catalysing the production of stilbenes. We have previously reported that the VpSTS29 gene plays an important role in powdery mildew resistance in Vitis pseudoreticulata. However, the synthesis and accumulation of these stilbene products in plant cells remain unclear. Here, we demonstrate that VpSTS29 is present in cytosolic oil bodies and can be transported into the vacuole at particular plant-developmental stages. Western blot and high-performance liquid chromatography showed that STS and trans-piceid accumulated in senescent grape leaves and in pVpSTS29::VpSTS29-expressing Arabidopsis during age-dependent leaf senescence. Subcellular localisation analyses indicated VpSTS29-GFP was present in the cytoplasm and in STS-containing bodies in Arabidopsis. Nile red staining, co-localisation and immunohistochemistry analyses of leaves confirmed that the STS-containing bodies were oil bodies and that these moved randomly in the cytoplasm and vacuole. Detection of protein profiles revealed that no free GFP was detected in the pVpSTS29::VpSTS29-GFP-expressing protoplasts or in Arabidopsis during the dark-light cycle, demonstrating that GFP fluorescence distributed in the STS-containing bodies and vacuole was the VpSTS29-GFP fusion protein. Intriguingly, in comparison to the controls, over-expression of VpSTS29 in Arabidopsis resulted in relatively high levels of trans-piceid, chlorophyll content and of photochemical efficiency accompanied by delayed leaf senescence. These results provide exciting new insights into the subcellular localisation of STS in plant cells and information about stilbene synthesis and storage.

The long-term results of this method show an 80% success rate in lowering intraocular pressure over 20 years. The surgical technique is demonstrated in detail with the help of a video of the operation and which is available online. For more than 15 years trabeculectomy has been performed with the use of antifibrotic substances, such as mitomycin C. Long-term treatment with antiglaucoma eyedrops leads to a proven inflammation of the conjunctiva and the ocular surface with an increase in lymphocytes, mast cells, and fibroblasts. Discontinuation of antiglaucoma therapy in turn allows regeneration of the ocular surface. From the knowledge gained from these histopathological studies it has been recommended to stop glaucoma treatment prior to glaucoma surgery and to pretreat the conjunctiva with eyedrops containing cortisone. Administration of nonsteroidal antiphlogistic substances or local steroids to the conjunctiva 4 weeks prior to surgery increases long-term success of the filtering bleb function. PMID- 29589147 TI - [Primary vitreoretinal lymphoma]. AB - Primary vitreoretinal lymphoma (PVRL) is the most common intraocular lymphoma. It is a high grade malignant B-cell lymphoma, which is thought to arise in the retina. It often infiltrates the central nervous system (CNS) and is therefore associated with a poor prognosis. The PVRL must be differentiated from other forms of intraocular lymphoma, such as the low-grade B-cell lymphoma that rarely arises in the choroid. The choroidal lymphomas do not spread to the brain, they can be treated with low-dose external beam radiotherapy and the patients have a good prognosis. Since PVRL is a relatively rare tumor, there is little information with respect to its true incidence, to any geographical or ethnic variability and to the main risk factors apart from an association with immunosuppression, as a result of HIV or Epstein-Barr virus infections. The treatment of PVRL is very variable between oncology centres and is also dependent on the unilaterality or bilaterality of disease and whether there is any concomitant CNS involvement. Further studies and research projects in this field are necessary in order to diagnose PVRL at an early stage and to develop new targeted individualized treatment. PMID- 29589149 TI - [Emigration-an option for African resident physicians? : Opinions from Tanzania and Ethiopia]. AB - BACKGROUND: Globally, the majority of visually impaired persons live in low- and middle-income countries. One of the reasons is a lack of ophthalmologists in the respective countries. Migration of qualified personnel would be an additional strain on ophthalmological patient care. OBJECTIVE: This analysis aimed at evaluating the attitude of African residents in ophthalmology towards working in their home country or migrating abroad and comparing these findings with existing data also with respect to possible interventions. MATERIAL AND METHODS: In 2016 and 2017, participants of ophthalmological training courses for residents in Dar es Salaam (Tanzania) and Addis Ababa (Ethiopia) as well as residents from Moshi (Tanzania) were interviewed on possible migration with the help of a questionnaire. RESULTS: In total 60 questionnaires were analyzed. The main reasons for staying in the home country were: "want to support/serve community", "family" as well as "high demand of specialists". Prime motives for possible migration were: "better income", "better working structure/equipment" and "better education". CONCLUSION: Links between German and African eye hospitals as they are supported, for example by the working group International Ophthalmology of the German Ophthalmological Society (DOG) and the German Committee for the Prevention of Blindness (DKVB), can contribute to improve some of the main reasons of migration, such as insufficient education, working structures and equipment and thus help to prevent a brain drain. PMID- 29589150 TI - Assessment of the pollution and ecological risk of lead and cadmium in soils. AB - The aim of the study was to assess the content, distribution, soil binding capacity, and ecological risk of cadmium and lead in the soils of Malopolska (South Poland). The investigation of 320 soil samples from differently used land (grassland, arable land, forest, wasteland) revealed a very high variation in the metal content in the soils. The pollution of soils with cadmium and lead is moderate. Generally, a point source of lead and cadmium pollution was noted in the study area. The highest content of cadmium and lead was found in the northwestern part of the area-the industrial zones (mining and metallurgical activity). These findings are confirmed by the arrangement of semivariogram surfaces and bivariate Moran's correlation coefficients. Among the different types of land use, forest soils had by far the highest mean content of bioavailable forms of both metals. The results showed a higher soil binding capacity for lead than for cadmium. However, for both metals, extremely high (class 5) accumulation capacities were dominant. Based on the results, the investigated soils had a low (Pb) and moderate (Cd) ecological risk on living components. Soil properties, such as organic C, pH, sand, silt, and clay content, correlated with the content of total and bioavailable forms of metals in the soils. The correlations, despite being statistically significant, were characterized by very low values of correlation coefficient (r = 0.12-0.20, at p <= 0.05). Therefore, the obtained data do not allow to define any conclusions as to the relationships between these soil properties. However, it must be highlighted that there was a very strong positive correlation between the total content of cadmium and lead and their bioavailable forms in the soils. PMID- 29589151 TI - EACR-MRS conference on Seed and Soil: In Vivo Models of Metastasis. AB - New experimental tools are urgently required to better understand the metastatic process. The importance of such tools is underscored by the fact that many anti cancer therapies are generally ineffective against established metastases. This makes a major contribution to the fact that metastatic spread is responsible for over 90% of cancer patient deaths. It was therefore timely that the recent "Seed and Soil: In Vivo Models of Metastasis" conference held in Berlin, Germany (27-29 of November 2017) aimed to give an in-depth overview of the latest research models and tools for studying metastasis, and to showcase recent findings from world-leading metastasis researchers. This Meeting Report summarises the major themes of this ground-breaking conference. PMID- 29589152 TI - Genetic test utilization and diagnostic yield in adult patients with neurological disorders. AB - To determine the diagnostic yield of different genetic test modalities in adult patients with neurological disorders, we evaluated all adult patients seen for genetic diagnostic evaluation in the outpatient neurology practice at the University of Pennsylvania between January 2016 and April 2017 as part of the newly created Penn Neurogenetics Program. Subjects were identified through our electronic medical system as those evaluated by the Program's single clinical genetic counselor in that period. A total of 377 patients were evaluated by the Penn Neurogenetics Program in different settings and genetic testing recommended. Of those, 182 (48%) were seen in subspecialty clinic setting and 195 (52%) in a General Neurogenetics Clinic. Genetic testing was completed in over 80% of patients in whom it was recommended. The diagnostic yield was 32% across disease groups. Stratified by testing modality, the yield was highest with directed testing (50%) and array comparative genomic hybridization (45%), followed by gene panels and exome testing (25% each). In conclusion, genetic testing can be successfully requested in clinic in a large majority of adult patients. Age is not a limiting factor for a genetic diagnostic evaluation and the yield of clinical testing across phenotypes (almost 30%) is consistent with previous phenotype-focused or research-based studies. These results should inform the development of specific guidelines for clinical testing and serve as evidence to improve reimbursement by insurance payers. PMID- 29589153 TI - An Exploratory Study of Dapagliflozin for the Attenuation of Albuminuria in Patients with Heart Failure and Type 2 Diabetes Mellitus (DAPPER). AB - BACKGROUND AND AIMS: Sodium-dependent glucose transporter-2 (SGLT-2) inhibitors, which are anti-diabetic drugs, reportedly decrease the incidence of cardiovascular events in high-risk patients with cardiovascular diseases, and thus chronic heart failure (CHF). SGLT-2 inhibitors also decrease albuminuria in patients with type 2 diabetes mellitus (T2D). Since albuminuria is a biomarker of not only chronic kidney disease but also cardiovascular events, we hypothesized that, among T2D patients with CHF, SGLT-2 inhibitors will decrease the extent of albuminuria and also improve CHF concomitantly. METHODS: DAPPER (UMIN000025102) is a multicenter, randomized, open-labeled, parallel-group, standard treatment controlled study, which is designed to evaluate whether dapagliflozin, one of the SGLT-2 inhibitors, decreases albuminuria in T2D patients with CHF and exerts cardioprotective effects on the failing heart. The patients are randomized to either of the dapagliflozin (5 or 10 mg, once daily orally) or control group (administration of anti-diabetic drugs administered other than SGLT 2 inhibitors). The estimated number of patients that need to be enrolled is 446 in total (223 in each group). The primary objective is the changes in the urinary albumin-to-creatinine ratio from the baseline after 2-year treatment. The key secondary objectives are (1) the safety of dapagliflozin and (2) the cardiovascular and renal efficacies of dapagliflozin. CONCLUSION AND PERSPECTIVES: DAPPER study investigates whether dapagliflozin decreases albuminuria and exerts beneficial effects on the failing heart in T2D patients. (UMIN000025102). PMID- 29589154 TI - Identification of curable high-risk prostate cancer using radical prostatectomy alone: who are the good candidates for undergoing radical prostatectomy among patients with high-risk prostate cancer? AB - BACKGROUND: Currently, there is no consensus regarding which patients with high risk prostate cancer (PCa) would benefit the most by radical prostatectomy (RP). We aimed to identify patients with high-risk PCa who are treatable by RP alone. METHODS: We retrospectively reviewed data on 315 patients with D'Amico high-risk PCa who were treated using RP without neoadjuvant or adjuvant therapy at the institutions of the Yamaguchi Uro-Oncology Group between 2009 and 2013. The primary endpoint was biochemical progression-free survival (bPFS) after RP. Risk factors for biochemical progression were extracted using the Cox proportional hazard model. We stratified the patients with high-risk PCa into 3 subgroups based on bPFS after RP using the risk factors. RESULTS: At a median follow-up of 49.9 months, biochemical progression was observed in 20.5% of the patients. The 2 and 5-year bPFS after RP were 89.4 and 70.0%, respectively. On multivariate analysis, Gleason score (GS) at biopsy (>= 8, HR 1.92, p < 0.05) and % positive core (>= 30%, HR 2.85, p < 0.005) were independent predictors of biochemical progression. Patients were stratified into favorable- (0 risk factor; 117 patients), intermediate- (1 risk factor; 127 patients), and poor- (2 risk factors; 57 patients) risk groups, based on the number of predictive factors. On the Cox proportional hazard model, this risk classification model could significantly predict biochemical progression after RP (favorable-risk, HR 1.0; intermediate-risk, HR 2.26; high-risk, HR 5.03; p < 0.0001). CONCLUSION: The risk of biochemical progression of high-risk PCa after RP could be stratified by GS at biopsy (>= 8) and % positive core (>= 30%). PMID- 29589155 TI - Accuracy of tumor segmentation from multi-parametric prostate MRI and 18F-choline PET/CT for focal prostate cancer therapy applications. AB - BACKGROUND: The study aims to assess the accuracy of multi-parametric prostate MRI (mpMRI) and 18F-choline PET/CT in tumor segmentation for clinically significant prostate cancer. 18F-choline PET/CT and 3 T mpMRI were performed in 10 prospective subjects prior to prostatectomy. All subjects had a single biopsy confirmed focus of Gleason >= 3+4 cancer. Two radiologists (readers 1 and 2) determined tumor boundaries based on in vivo mpMRI sequences, with clinical and pathologic data available. 18F-choline PET data were co-registered to T2-weighted 3D sequences and a semi-automatic segmentation routine was used to define tumor volumes. Registration of whole-mount surgical pathology to in vivo imaging was conducted utilizing two ex vivo prostate specimen MRIs, followed by gross sectioning of the specimens within a custom-made 3D-printed plastic mold. Overlap and similarity coefficients of manual segmentations (seg1, seg2) and 18F-choline based segmented lesions (seg3) were compared to the pathologic reference standard. RESULTS: All segmentation methods greatly underestimated the true tumor volumes. Human readers (seg1, seg2) and the PET-based segmentation (seg3) underestimated an average of 79, 80, and 58% of the tumor volumes, respectively. Combining segmentation volumes (union of seg1, seg2, seg3 = seg4) decreased the mean underestimated tumor volume to 42% of the true tumor volume. When using the combined segmentation with 5 mm contour expansion, the mean underestimated tumor volume was significantly reduced to 0.03 +/- 0.05 mL (2.04 +/- 2.84%). Substantial safety margins up to 11-15 mm were needed to include all tumors when the initial segmentation boundaries were drawn by human readers or the semi automated 18F-choline segmentation tool. Combining MR-based human segmentations with the metabolic information based on 18F-choline PET reduced the necessary safety margin to a maximum of 9 mm to cover all tumors entirely. CONCLUSIONS: To improve the outcome of focal therapies for significant prostate cancer, it is imperative to recognize the full extent of the underestimation of tumor volumes by mpMRI. Combining metabolic information from 18F-choline with MRI-based segmentation can improve tumor coverage. However, this approach requires confirmation in further clinical studies. PMID- 29589156 TI - Effects of non-surgical periodontal therapy on periodontal laboratory and clinical data as well as on disease activity in patients with rheumatoid arthritis. AB - OBJECTIVES: To compare the effect of non-surgical periodontal therapy on clinical and inflammatory parameters in patients with moderate to severe chronic periodontitis (CP) and rheumatoid arthritis (RA) (RA-CP) with that in CP patients without RA. MATERIAL AND METHODS: Eighteen patients with RA-CP and 18 systemically healthy patients with CP were treated with scaling and root planing (SRP) within 24 h. At baseline, and at 3 and 6 months after SRP, clinical periodontal parameters, inflammatory markers, and microorganisms in subgingival biofilm were assessed. In addition, disease activity markers of RA (DAS28, CRP, ESR) and specific antibodies (RF) were monitored in the RA-CP group. RESULTS: In both groups, non-surgical therapy yielded to statistically significant improvements in all investigated clinical periodontal variables; in RA patients, a statistically significant decrease in serum-CRP was seen at 3 months. At all time-points, levels of inflammatory markers in GCF were higher in RA-CP than in CP patients. Counts of Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola decreased statistically significantly in CP but not in the RA CP group. Changes of DAS28 correlated positively with those of P. gingivalis and negatively with the plaque index. CONCLUSIONS: Within their limits, the present data suggest that (a) non-surgical periodontal therapy improves periodontal conditions in CP patients with and without RA and (b) in patients with RA, eradication of P. gingivalis in conjunction with a high level oral hygiene may transiently decrease disease activity of RA. CLINICAL RELEVANCE: In patients with RA and CP, non-surgical periodontal therapy is a relevant modality not only to improve the periodontal condition but also to decrease RA activity. PMID- 29589157 TI - Association of sleep bruxism with oral health-related quality of life and sleep quality. AB - OBJECTIVES: To compare the oral health-related quality of life (OHRQoL) and sleep quality of subjects with and without sleep bruxism (SB). MATERIALS AND METHODS: Participants of both genders were assigned as bruxers (n = 30, age 21-45 years) and non-bruxers (n = 30, age 24-40 years). SB was clinically diagnosed and confirmed with an electromyography/electrocardiograph portable device (Bruxoff). The OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). The sleep quality was determined using the Pittsburg Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) questionnaires. OHIP-14, PSQI, and ESS data were analyzed by one-way ANOVA, considering a significance level of 5%. RESULTS: Bruxers had worse OHRQoL (mean = 16.43) than controls (mean = 4.1), with an effect size (ES) of 1.58. Moreover, SB volunteers showed the highest PSQI scores (mean = 7.07; ES = 0.82) and excessive daytime sleepiness (mean = 10.33; ES = 0.65), compared to non-bruxers (means = 4.7 and 7.8, respectively). CONCLUSIONS: SB may be associated with a negative impact on OHRQoL and sleep quality. CLINICAL RELEVANCE: Determining that SB may have a marked role in OHRQoL and sleep quality is important for dental professionals establish proper multifactorial management, and understand patient-related psychosocial aspects.

PMID- 29589159 TI - Ten alien chromosome additions of Gossypium hirsutum-Gossypium bickii developed by integrative uses of GISH and species-specific SSR markers. AB - Gossypium bickii: (2n = 26, G1G1), a wild diploid cotton, carries many favourable traits. However, these favourable traits cannot be directly transferred into G. hirsutum (2n = 52, AADD) cultivars due to the differences in genomes. Monosomic alien addition lines (MAALs) are considered an invaluable tool for the introgression of genes of interest from wild relatives into cultivated crops. In this study, the G. hirsutum-G. bickii amphidiploid (2n = 78, AADDG1G1) was backcrossed with G. hirsutum to develop alien additions containing individual G. bickii chromosomes in a G. hirsutum background. Genomic in situ hybridization was employed to detect the number of alien chromosomes added to the backcross progenies. A total of 183 G. bickii-specific DNA markers were developed to discriminate the identities of the G. bickii chromosomes added to G. hirsutum and assess the alien chromosome transmissibility. Chromosomes 4Gb and 13Gb showed the highest transmissibility, while chromosomes 1Gb, 7Gb and 11Gb showed the lowest. Ten of the 13 possible G. hirsutum-G. bickii MAALs were isolated and characterized, which will lay the foundation for transferring resistance genes of G. bickii into G. hirsutum, as well as for gene assignment, physical mapping, and selective isolation and mapping of cDNAs for particular G. bickii chromosomes. The strategies of how to use MAALs to develop varieties with the trait of interest from wild species (such as glanded plant-glandless seed) were proposed and discussed. PMID- 29589160 TI - HLA-C*06:02-independent, gender-related association of PSORS1C3 and PSORS1C1/CDSN single-nucleotide polymorphisms with risk and severity of psoriasis. AB - Psoriasis vulgaris (PsV) is a common, chronic skin disease with a complex genetic and environmental etiology. We investigated, in 461 psoriatic patients and 454 healthy controls, the associations with psoriasis of four single-nucleotide polymorphisms (SNPs) from the psoriasis susceptibility 1 (PSORS1) interval: rs1062470 (PSORS1C1/CDSN), rs887466 (PSORS1C3), rs2894207 and rs10484554 (LOC105375015). The minor alleles of three SNPs (rs1062470A, rs2894207C and rs10484554T) strongly increased the disease risk (OR = 2.17, p < 0.0001; OR = 2.33, p < 0.0001 and OR = 2.68, p < 0.0001, respectively), whereas the minor A allele of rs887466 exerted a protective effect (OR = 0.73, p = 0.001). The strength of association for SNPs was the highest in patients with very early onset psoriasis (<= 20 years), while in late onset psoriasis (> 40 years) the association was the weakest. The haplotype rs1062470A/rs887466G/rs2894207C/rs10484554T highly significantly increased the disease risk (OR = 3.58, p = 8.0e-027), while the haplotypes rs1062470G/rs887466A/rs2894207T/rs10484554C and rs1062470G/rs887466G/rs2894207T/rs10484554C were strongly protective (OR = 0.65, p = 0.002 and OR = 0.55, p = 2.4e-009, respectively). Additionally, we showed a HLA-C*06:02-independent gender-related effect of the rs887466A allele which was protective against psoriasis in males (OR = 0.61, p = 9.2e-005), but not in females (p = 0.66). We also demonstrated a correlation of PASI score value with rs1062470 genotype, and again only in male patients (p = 0.006) and HLA-C*06:02 independent. Our results show, for the first time, the male-only associations of the PSORS1C3 gene with psoriasis risk and of the PSORS1C1/CDSN gene with severity of disease. However, the age dependent associations need to be validated in larger sample sizes as well as in other populations. PMID- 29589161 TI - Phyllanthus rufuschaneyi: a new nickel hyperaccumulator from Sabah (Borneo Island) with potential for tropical agromining. AB - BACKGROUND: Nickel hyperaccumulator plants are of much interest for their evolution and unique ecophysiology, and also for potential applications in agromining-a novel technology that uses plants to extract valuable metals from soil. The majority of nickel hyperaccumulators are known from ultramafic soils in tropical regions (Cuba, New Caledonia and Southeast Asia), and one genus, Phyllanthus (Phyllanthaceae), is globally the most represented taxonomic entity. A number of tropical Phyllanthus-species have the potential to be used as 'metal crops' in agromining operations mainly because of their ease in cultivation and their ability to attain high nickel concentrations and biomass yields. RESULTS: One of the most promising species globally for agromining, is the here newly described species Phyllanthus rufuschaneyi. This species can be classified in subgenus Gomphidium on account of its staminate nectar disc and pistillate entire style and represents the most western species of this diverse group. The flower structure indicates that this species is probably pollinated by Epicephala moths. CONCLUSIONS: Phyllanthus rufuschaneyi is an extremely rare taxon in the wild, restricted to Lompoyou Hill near Kinabalu Park in Sabah, Malaysia. Its utilization in agromining will be a mechanism for conservation of the taxon, and highlights the importance of habitat and germplasm preservation if rare species are to be used in novel green technologies.

AB - BACKGROUND: Femoral malposition is the first cause for graft rupture during ACL reconstruction. Arthroscopic landmarks can be difficult to identify. So, landmark has to be found for reliable tunnel placement. A proximal-distal reference was described as "Apex reference" reported by Hart et al. but no posterior/anterior reference exists in the literature. The purpose of this study was to do a 3D CT scan assessment of the femoral tunnel positioning using the Capsular Line Reference (CLR) as a landmark for posterior/anterior placement in ACL reconstruction. We hypothesized the CLR could provide a precise and reliable antero/posterior femoral tunnel positioning less than 2 mm from the Bernard & Hertel posterior quarter. METHODS: Seven cadaveric knee specimens with a mean age of 79.2 +/- 11 years were used. Using standard approaches, the CLR was identified corresponding to a white line (the capsule) appearing at the posterior border of the femoral condyle after bony debridement of the medial and posterior part of the lateral femoral condyle. The center of the tunnel was marked. An inside-out technique with anteromedial drilling technique was performed using an 8-mm diameter reamer. The distal femurs were sawed and a CT-scan was done for each specimen to obtain 3-dimensional image reconstructions. These 3D reconstructions were analyzed to measure the position tunnel center on the posterior/anterior axis and the distance from the posterior/anterior quadrant according to the Bernard & Hertel method. RESULTS: The mean position for the posterior/anterior axis was 27.0 +/- 1.8% (25-28.9) with a median of 26.9%. The position from the first quarter of the Bernard & Hertel method was 0.9 +/- 0.8 mm (0-1.8) with a median of 0.8 mm. CONCLUSION: The CLR is a reliable and reproducible arthroscopic landmark to place the femoral tunnel for ACL reconstruction in the anterior/posterior axis. Proximal/distal position depends on the choice of the surgeon to reproduce anteromedial or posterolateral fibers.

AB - BACKGROUND: Although IPMN are thought to represent a whole-gland disease, segmental resection remains the most frequently performed treatment. We sought to determine the rates, patterns, and predictors of IPMN progression in the pancreatic remnant following segmental resection of noninvasive or microinvasive IPMN. METHODS: A prospectively maintained database was queried to identify all patients who underwent resection of noninvasive or microinvasive IPMN (<= 10 mm of invasive component) between 1989 and 2015. Progression (recurrence) was defined as either the development of cancer, a new IPMN cystic lesion > 1 cm or >= 50% increase in the diameter of residual IPMN lesions in the remnant. Univariate and multivariate cox regression models were created to determine predictors of progression. RESULTS: A total of 319 patients underwent resection for noninvasive and microinvasive IPMN. The median age was 68, 53% had branch duct (BD) IPMN, and 6% had microinvasive disease. After a median follow-up of 42 months, 71 patients (22%) experienced IPMN progression. Within this group of 71 patients, 11 (16% of recurrence) developed invasive cancer in the pancreatic remnant after a median of 28 months. Twelve patients (17%) experienced progression > 5 years following initial resection. On multivariate analysis, a distal location of the initial lesion was associated with an increased risk of progression (multivariate hazards ratio = 2.43, confidence interval 1.47-4.0, p < 0.001). CONCLUSIONS: In this study, 22% of patients had disease progression following resection of noninvasive or microinvasive IPMN; 16% of these progressions represented invasive disease. These patients represent a high-risk group and should undergo long-term radiographic surveillance. PMID- 29589163 TI - Casual Sexual Scripts on the Screen: A Quantitative Content Analysis. AB - While existing content analyses have provided insightful information in terms of contextual factors and frequency of sexual behaviors, not much is known about the relational context in which sexual depictions generally occur. The current study addresses this void by employing content analytic methods to measure the frequency and context of depictions of sexual behavior within nine popular television shows produced in the U.S., while taking into account the type of sexual behavior. The results suggest that, in the analyzed television shows, sexual behaviors within a casual sexual context were almost as frequently shown as sexual behaviors within a committed relationship context. Whereas sexual behaviors within a committed relationship context were mainly limited to passionate kissing, sexual behaviors within a casual sexual context mostly consisted of explicit portrayals of sexual intercourse. Additionally, genre seemed to be an important factor when examining casual sexual television content. The situational comedy genre, for example, had no explicit portrayals of intercourse and mainly portrayed kissing couples within a committed relationship. The comedy drama genre, on the contrary, had the largest proportion of explicit sexual portrayals, usually between casual sexual partners. A second goal of this study was to analyze the portrayals of the typical casual sexual experience script and the typical casual sexual relationship script in which these sexual behaviors often occur. For instance, our analyses revealed that female characters were more likely to initiate casual sex compared to male characters. Moreover, casual sex often occurred between former partners. PMID- 29589165 TI - Self-Directed Gambling Changes: Trajectory of Problem Gambling Severity in Absence of Treatment. AB - Most problem gamblers do not seek formal treatment, recovering on their own through cognitive re-appraisal or self-help strategies. Although barriers to treatment have been extensively studied, there is a paucity of research on self directed changes in problem gambling and very few studies have examined these changes prospectively. The aim of this study was to examine the trajectory of gambling severity and behavior change over an 18-month period, among a sample of non-treatment seeking/attending problem gamblers recruited from the community (N = 204) interested in quitting or reducing gambling. Separate mixed effects models revealed that in absence of formal treatment, significant reductions in gambling severity, frequency, and amount gambled could be observed over the course of a 6 to 9-month period and that changes experienced within the first 12 months were maintained for an extended 6 months. Problem gambling severity at baseline was significantly associated with changes in severity over time, such that participants with more severe gambling problems demonstrated greater reductions in their gambling severity over time. A total of 11.1% of participants gambled within a low-risk threshold at 18 months, although 28.7% of the sample reported consecutive gambling severity scores below problem levels for the duration of 1 year or longer. The findings suggest that among problem gamblers motivated to quit or reduce their gambling, significant self-directed changes in gambling severity can occur over a relatively short time. Additional prospective studies are needed to document the role of specific self-help tools or thought processes in exacting gambling changes. PMID- 29589166 TI - Evidence of Skill and Strategy in Daily Fantasy Basketball. AB - Using hand-collected data from DraftKings.com, a major daily fantasy sports website, we analyze draft selections of thousands of participants in daily fantasy basketball (DFB). In our study, the first thorough examination of DFB, we show that DFB is a game in which skill is necessary for success. Using econometric analysis, we find that winning participants utilize different strategies than losing participants; for example, winning participants more frequently select NBA rookies and international players. We also find that participants paying to enter more lineups in a given contest earn profits far more often than those entering few lineups, indicating that the number of lineups entered can serve as a proxy for skill. Additionally, we provide a thorough discussion of industry characteristics, prior literature, and gameplay, which should help readers familiarize themselves with this burgeoning fantasy sports variant. This study should further the literature on the contentious activity, which has been outlawed in many U.S. states and continues to elicit controversy. PMID- 29589167 TI - Cartilage Metabolism is Modulated by Synovial Fluid Through Metalloproteinase Activity. AB - Synovial fluid (SF) contains various cytokines that regulate chondrocyte metabolism and is dynamically associated with joint disease. The objective of this study was to investigate the effects of diluted normal SF on catabolic metabolism of articular cartilage under inflammatory conditions. For this purpose, SF was isolated from healthy bovine joints, diluted, and added to cartilage explant cultures stimulated with interleukin-1 (IL-1) for 12 days. The kinetic release of sulfated glycosaminoglycan (sGAG) and collagen, as well as nitric oxide and gelatinase matrix metalloproteinases were analyzed in the supernatant. Chondrocyte survival and matrix integrity in the explants were evaluated with Live/Dead and histological staining. Diluted synovial fluid treatment suppressed sGAG and collagen release, downregulated the production of nitric oxide and matrix metalloproteinases, reduced IL-1-induced chondrocyte death, and rescued matrix depletion. Our results demonstrate that normal SF can counteract inflammation-driven cartilage catabolism. This study reports on the protective function of healthy SF and the therapeutic potential of recapitulation of SF for cartilage repair. PMID- 29589168 TI - From Tension to Compression: Asymmetric Mechanical Behaviour of Trabecular Bone's Organic Phase. AB - Trabecular bone is a cellular composite material comprising primarily of mineral and organic phases with their content ratio known to change with age. Therefore, the contribution of bone constituents on bone's mechanical behaviour, in tension and compression, at varying load levels and with changing porosity (which increases with age) is of great interest, but remains unknown. We investigated the mechanical response of demineralised bone by subjecting a set of bone samples to fully reversed cyclic tension-compression loads with varying magnitudes. We show that the tension to compression response of the organic phase of trabecular bone is asymmetric; it stiffens in tension and undergoes stiffness reduction in compression. Our results indicate that demineralised trabecular bone struts experience inelastic buckling under compression which causes irreversible damage, while irreversible strains due to microcracking are less visible in tension. We also identified that the values of this asymmetric mechanical response is associated to the original bone volume ratio (BV/TV). PMID- 29589169 TI - Polarisation vision: overcoming challenges of working with a property of light we barely see. AB - In recent years, the study of polarisation vision in animals has seen numerous breakthroughs, not just in terms of what is known about the function of this sensory ability, but also in the experimental methods by which polarisation can be controlled, presented and measured. Once thought to be limited to only a few animal species, polarisation sensitivity is now known to be widespread across many taxonomic groups, and advances in experimental techniques are, in part, responsible for these discoveries. Nevertheless, its study remains challenging, perhaps because of our own poor sensitivity to the polarisation of light, but equally as a result of the slow spread of new practices and methodological innovations within the field. In this review, we introduce the most important steps in designing and calibrating polarised stimuli, within the broader context of areas of current research and the applications of new techniques to key questions. Our aim is to provide a constructive guide to help researchers, particularly those with no background in the physics of polarisation, to design robust experiments that are free from confounding factors. PMID- 29589170 TI - Computerized tests to evaluate recovery of cognitive function after deep sedation with propofol and remifentanil for colonoscopy. AB - The use of sedation for diagnostic procedures including gastrointestinal endoscopy is rapidly growing. Recovery of cognitive function after sedation is important because it would be important for most patients to resume safe, normal life soon after the procedure. Computerized tests have shown being accurate descriptors of cognitive function. The purpose of the present study was to evaluate the time course of cognitive function recovery after sedation with propofol and remifentanil. A prospective observational double blind clinical study conducted in 34 young healthy adults undergoing elective outpatient colonoscopy under sedation with the combination of propofol and remifentanil using a target controlled infusion system. Cognitive function was measured using a validated battery of computerized cognitive tests (CogstateTM, Melbourne, Australia) at different predefined times: prior to starting sedation (Tbaseline), and then 10 min (T10), 40 min (T40) and 120 min (T120) after the end of colonoscopy. Tests included the assessment of psychomotor function, attention, visual memory and working memory. All colonoscopies were completed (median time: 26 min) without significant adverse events. Patients received a median total dose of propofol and remifentanil of 149 mg and 98 ug, respectively. Psychomotor function and attention declined at T10 but were back to baseline values at T40 for all patients. The magnitude of psychomotor task reduction was large (d = 0.81) however 100% of patients were recovered at T40. Memory related tasks were not affected 10 min after ending sedation. Cognitive impairment in attention and psychomotor function after propofol and remifentanil sedation was significant and large and could be easily detected by computerized cognitive tests. Even though, patients were fully recovered 40 min after ending the procedure. From a cognitive recovery point of view, larger studies should be undertaken to propose adequate criteria for discharge after sedation. PMID- 29589171 TI - Lowered dose full-spine radiography in pediatric patients with idiopathic scoliosis. AB - PURPOSE: To optimize our standard full-spine radiography with respect to diagnostic quality and dose. METHODS: A phantom study was performed to establish an optimal posterior-anterior view (PA) full spine protocol having the lowest dose with non-inferior quality compared to standard. We then applied this protocol in 40 pediatric patients (group B). The radiographs were scored on six criteria by a pediatric radiologist and orthopedist and compared to the scores of 40 PA full spine radiographs performed in 2013 with standard protocol (group A). Radiation dose was assessed by dose area product (DAP) and effective dose (E). Statistical analysis included independent samples t test, Mann-Whitney U test and intra-class correlation coefficient (ICC). RESULTS: An optimized protocol was defined (0.2 mm Cu filter, 0.87 relative exposure, with grid). Mean age was 13.3 +/- 1.6 years for group A and 13.4 +/- 1.7 years for group B. For group B, the mean DAP was 47.0 uGy m2 with an E of 0.13 mSv. For group A, the mean DAP was 85.3 uGy m2 with an E of 0.24 mSv. This represents a dose reduction of 45%. Mean image quality scores for group A (27.9 +/- 2.4) and group B (28.1 +/- 2.3) were similar (p = 0.612). Interobserver agreement was observed to be excellent (ICC 0.92). CONCLUSION: This study demonstrates that a low-dose full-spine radiograph can be performed in patients with idiopathic scoliosis without loss of image quality.

PMID- 29589172 TI - Utilization of phage display to identify antigenic regions in the PCV2 capsid protein for the evaluation of serological responses in mice and pigs. AB - Porcine circovirus 2 (PCV2) is associated with a series of swine diseases. There is a great interest in improving our understanding of the immunology of PCV2, especially the properties of the viral capsid protein Cap-PCV2 and how they relate to the immunogenicity of the virus and the subsequent development of vaccines. Phage display screening has been widely used to study binding affinities for target proteins. The aim of this study was to use phage display screening to identify antigenic peptides in the PCV2 capsid protein. After the selection of peptides, five of them presented similarity to sequences found in cap-PCV2, and four peptides were synthesized and used for immunization in mice: 51-CTFGYTIKRTVT-62 (PS14), 127-CDNFVTKATALTY-138 (PS34), 164-CKPVLDSTIDY-173 (PC12), and 79-CFLPPGGGSNT-88 (PF1). Inoculation with the PC12 peptide led to the highest production of antibodies. Furthermore, we used the PC12 peptide as an antigen to examine the humoral response of swine serum by ELISA. The sensitivity and specificity of this assay was 88.9% and 92.85%, respectively. Altogether, characterization of immunogenic epitopes in the capsid protein of PCV2 may contribute to the improvement of vaccines and diagnostics. PMID- 29589173 TI - Do dihydroxymagnesium carboxylates form Grignard-type reagents? A theoretical investigation on decarboxylative fragmentation. AB - Dihydroxymagnesium carboxylates [(OH)2MgO2CR] were probed for decarboxylation on a theoretical level, by utilizing both Moller-Plesset perturbation theory (MP2) and density functional theory (B3LYP-DFT) computations. This study is connected to the question of whether this recently introduced, astrobiologically relevant chemical class may form Grignard-type reagent molecules. To extract trends for a broad molecular mass range, different linear alkyl chain lengths between C4 and C11 were computed. The forward energy barrier for decarboxylation reactions increases linearly as a function of the ligand's chain length. Decarboxylation type fragmentations of these organomagnesium compounds seem to be improbable in non-catalytic, low energetic environments. A high forward energy barrier (EMP2 > 55 kcal mol-1) towards a described transition state restricts the release of CO2. Nevertheless, we propose the release of CO2 on a theoretical level, as been revealed via an intramolecular nucleophilic attack mechanism. Once the challenging transition state for decarboxylation is overcome, a stable Mg-C bond is formed. These mechanistic insights were gained by help of natural bond orbital analysis. The Calpha atom (first carbon atom in the ligand chain attached to the carboxyl group) is thought to prefer binding towards the electrophilic magnesium coordination center, rather than towards the electrophilic CO2-carbon atom. Additionally, the putatively formed Grignard-type OH-bearing product molecules possess a more polarized Mg-C bond in comparison to RMgCl species. Therefore, carbanion formation from OH-bearing Grignard-type molecules is made feasible for triggering C-C bond formation reactions. Graphical abstract This study asks whether recently introduced, astrobiologically dihydroxymagnesium carboxylates form Grignard-type reagent molecules via decarboxylative fragmentation. PMID- 29589174 TI - Asking a Variety of Questions on Walk Rounds: a Pilot Study. AB - BACKGROUND: Morning walk rounds have lost some of their engagement while remaining a useful and valued practice. AIM: We created a pilot study to evaluate the impact on rounds of learning to asking a variety of different questions. SETTING: One-hour intervention sessions were voluntarily offered to members of the Department of Medicine and taught by an expert in the question, listen, and respond method. PARTICIPANTS: Participants included attendings and residents in Internal Medicine on medical teams. PROGRAM DESCRIPTION: Questionnaires were collected on six pre-intervention and six post-intervention days. Nine months later, an anonymous online survey was sent to participants asking about their use of a wider variety of questions. PROGRAM EVALUATION: Two hundred eight physicians (residents 175 (45.5%), attending physicians 25 (27.7%)) filled out pre intervention surveys. One hundred eighty-one physicians (residents 155 (40.3%), attending physicians 18 (20%)) filled out post-intervention surveys. When survey responses from the attendings and residents on the medical teams were combined, post-intervention rounds were perceived as more worthwhile (1.99 pre-intervention and 1.55 post-intervention, [95% confidence interval 1.831-2.143]) (p < 0.001) and more engaging (1.68 pre-intervention and 1.30 post-intervention, [95% confidence interval 1.407-1.688]) (p < 0.001).Non-medical teams' survey responses did not change. Patient census data indicated no significant difference in the hospital's census on the pre- and post-intervention dates. Spontaneous suggestions for improving rounds came largely from the residents and included teaching points, clinical pearls, patient focus, more interactive, increased dedicated time for teaching, inclusive/multidisciplinary, questions, and evidence based teaching. Of the participants who answered the online survey 9 months later, 75% (6/8) reported that they "actually asked a wider variety of types of questions." DISCUSSION: This pilot study indicates that the 1-h intervention of learning to ask a variety of different questions is associated with rounds that are rated as more worthwhile and engaging by the medical teams. PMID- 29589175 TI - Alkyl-Dimethylpyrazines in Mandibular Gland Secretions of Four Odontomachus Ant Species (Formicidae: Ponerinae). AB - Ponerine ants are known to contain mixtures of pyrazines in their mandibular glands. We analyzed the mandibular gland contents of four ponerine species (Odontomachus chelifer, O. erythrocephalus, O. ruginodis, and O. bauri) by gas chromatography coupled with mass spectrometry, and found that each species contains specific mixtures of trisubstituted alkylpyrazines among other volatiles. Attempts to identify alkylpyrazines solely by mass spectral interpretation is unrealistic because spectra of positional isomers are indistinguishable. To avoid misidentifications, we synthesized a large number of reference compounds and compared their mass spectral and gas chromatographic properties with those present in the Odontomachus species under investigation. Most of the compounds identified were 2-alkyl-3,5-dimethylpyrazines. Interestingly, when the third substituent was an isopentyl group, the two methyl groups were found to be located at the 2 and 5 ring positions. Using our data, we recognized several misidentifications in previous publications. PMID- 29589176 TI - Photodynamic inactivation in the expression of the Candida albicans genes ALS3, HWP1, BCR1, TEC1, CPH1, and EFG1 in biofilms. AB - The objective of this study was to evaluate the effects of photodynamic inactivation (PDI) on Candida albicans biofilms, evaluating its effects on gene expression of ALS3, HWP1, BCR1, TEC1, CPH1, and EFG1 by yeast. Three samples of C. albicans were used in this study: a clinical sample from a patient with HIV (39S), a clinical sample from a patient with denture stomatitis lesion (Ca30), and a standard strain ATCC 18804. The quantification of gene expression was related to the production of those genes in the samples referred above using quantitative polymerase chain reaction (qPCR) assay in real time. The photosensitizer methylene blue at 300 uM and erythrosine at 400 uM, sensitized with low-power laser (visible red, 660 nm) and green LED (532 nm), respectively, were used for PDI. Four groups of each sample and PDI protocol were evaluated: (a) P+L+: sensitization with the photosensitizer and irradiation with light, (b) P+L-: only treatment with the photosensitizer, (c) P-L+: only irradiation with light, and (d) P-L-: without sensitization with the dye and absence of light. The results were analyzed by t test, with a significance level of 5%. The photodynamic inactivation was able to reduce the expression of all genes for both treatments, laser and LED. The fold-decrease for the genes ALS3, HWP1, BCR1, TEC1, CPH1, and EFG1 were 0.73, 0.39, 0.77, 0.71, 0.67, and 0.60 for laser, respectively, and 0.66, 0.61, .050, 0.43, 0.54, and 0.66 for LED, respectively. It could be concluded that PDI showed a reduction in the expression of C. albicans genes, suggesting its virulence decrease. PMID- 29589178 TI - Anterior robotic approach in en-bloc sacrectomy: a preliminary experience. AB - En-bloc sacrectomy is a highly demanding surgical procedure necessary to obtain wide margin in sacral tumor. The double approach, anterior and posterior approach, is usually preferred for tumors extending proximally to S3 level where iliac internal vessels are at a higher risk for damage during posterior surgery. It can be justified also in selected cases to decrease the risk of posterior approach as in local recurrence or in patients who already underwent laparotomy. Our intent was to apply robotic-assisted techniques for performing anterior preparatory approach for sacrectomy surgery. Between December 2010 and December 2014, three cases of sacrectomies were performed in a previous robotic-assisted preparatory approach to separate the rectum from the tumor. Dissections were successfully performed in all cases close to the pelvic floor. The surgeon was able to position a Gore-Tex spacer between the anterior tumor surface and the rectum in all cases. The anterior dissections were performed with a perfect control of bleeding. No complications related to the anterior approach were reported. Robot-assisted surgery can be considered a valid and minimally invasive technique which allows a safe anterior dissection of the pelvic structures dividing tumors from surrounding tissues. It allows to place a spacer to protect organs during posterior sacral resection performed on the same day or at a later time. Further experiences are advocated to evaluate its efficiency in sacral tumors of greater size. PMID- 29589179 TI - Expression of Hypoxia Inducible Factor 1alpha Is Protein Kinase A-dependent in Primary Cortical Astrocytes Exposed to Severe Hypoxia. AB - The hypoxia inducible factor 1 (HIF-1) and the cyclic AMP-responsive element binding protein (CREB) are two transcription factors that have been studied in the context of neuronal survival and neurodegeneration. HIF-1 upregulation and CREB activation have been observed not only in neurons but also in astrocytes under conditions of hypoxia. We hypothesized that activation of CREB regulate HIF 1alpha expression in the nucleus of cortical astrocytes under in vitro ischemic condition. To test the hypothesis, we determined the effects of inhibiting the CREB activation pathway on the expression of HIF-1alpha protein in astrocytes exposed to CoCl2 and severe hypoxia (near anoxia, 0.1% O2). The results demonstrated that inhibition of CaMKII and CaMKIV had no effect on both HIF 1alpha and pCREB expression in cortical astrocytes exposed to CoCl2 and anoxia. In contrast, PKA inhibition lowered the expression of HIF-1alpha and pCREB expression. Furthermore, the inhibition of PKA but not CaMKII or CaMKIV increased cell death of astrocytes exposed to near anoxia. The results suggest that PKA plays an important role in the cell survival signaling pathways in astrocytes. PMID- 29589180 TI - Germline CDH1 mutations are a significant contributor to the high frequency of early-onset diffuse gastric cancer cases in New Zealand Maori. AB - New Zealand Maori have a considerably higher incidence of gastric cancer compared to non-Maori, and are one of the few populations worldwide with a higher prevalence of diffuse-type disease. Pathogenic germline CDH1 mutations are causative of hereditary diffuse gastric cancer, a cancer predisposition syndrome primarily characterised by an extreme lifetime risk of developing diffuse gastric cancer. Pathogenic CDH1 mutations are well described in Maori families in New Zealand. However, the contribution of these mutations to the high incidence of gastric cancer is unknown. We have used next-generation sequencing, Sanger sequencing, and Multiplex Ligation-dependent Probe Amplification to examine germline CDH1 in an unselected series of 94 Maori gastric cancer patients and 200 healthy matched controls. Overall, 18% of all cases, 34% of cases diagnosed with diffuse-type gastric cancer, and 67% of cases diagnosed aged less than 45 years carried pathogenic CDH1 mutations. After adjusting for the effect of screening known HDGC families, we estimate that 6% of all advanced gastric cancers and 13% of all advanced diffuse-type gastric cancers would carry germline CDH1 mutations. Our results demonstrate that germline CDH1 mutations are a significant contributor to the high frequency of diffuse gastric cancer in New Zealand Maori. PMID- 29589177 TI - Time-dependent antimicrobial effect of photodynamic therapy with TONS 504 on Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa (P. aeruginosa) is a major cause of infectious keratitis, which itself is a major cause of blindness worldwide. We have now evaluated the time-dependent effectiveness of photodynamic antimicrobial chemotherapy (PACT) with the chlorin derivative TONS 504 and a light-emitting diode (LED) on P. aeruginosa in vitro. PACT with TONS 504 (10 mg/L) and irradiation (30 J/m2) by an LED device that delivers light centered on a wavelength of 660 nm was applied to 1 * 106 colony-forming units of P. aeruginosa in liquid medium. The bacteria were then cultured at 37 degrees C for various times before assay of viability by determination of colony formation on agar plates. The effect of a second irradiation at 3 h after the initial LED exposure was also examined. Bacterial growth was markedly inhibited between 3 and 9 h after PACT with TONS 504, with the maximal effect being apparent at 3 h. Furthermore, a second exposure to LED irradiation at 3 h after the first treatment enhanced the inhibitory effect on bacterial growth. PACT with TONS 504 thus inhibited the growth of P. aeruginosa in a time-dependent manner, and an additional irradiation exposure applied 3 h after the first LED treatment greatly increased the effectiveness of PACT. This antibacterial system thus warrants further evaluation with regard to its potential effectiveness for the treatment of infectious keratitis. PMID- 29589181 TI - Mendelian Susceptibility to Mycobacterial Disease Caused by a Novel Founder IL12B Mutation in Saudi Arabia. AB - PURPOSE: Mendelian susceptibility to mycobacterial disease (MSMD) is a rare primary immunodeficiency predisposing congenitally affected individuals to diseases caused by weakly virulent mycobacteria, such as Bacillus Calmette-Guerin (BCG) vaccine strains and environmental mycobacteria. IL-12p40 deficiency is a genetic etiology of MSMD resulting in impaired IL-12- and IL-23-dependent IFN gamma immunity. Most of the reported patients with IL-12p40 deficiency originate from Saudi Arabia (30 of 52) and carry the recurrent IL12B mutation c.315insA (27 of 30). METHODS: Whole-exome sequencing was performed on three patients from two unrelated kindreds from Saudi Arabia with disseminated disease caused by a BCG vaccine substrain. RESULTS: Genetic analysis revealed a homozygous mutation, p.W60X, in exon 3 of the IL12B gene, resulting in complete IL12p40 deficiency. This mutation is recurrent due to a new founder effect. CONCLUSIONS: This report provides evidence for a second founder effect for recurrent mutations of IL12B in Saudi Arabia. PMID- 29589182 TI - Isolated acute lupus pneumonitis as the initial presentation of systemic lupus erythematosus in an 8-year-old girl. AB - Systemic lupus erythematosus (SLE) is a systemic autoimmune disease which has broad pleuropulmonary manifestations. One of the rare and mortal complications is acute lupus pneumonitis, which is reported very rarely, especially in childhood. Herein, we report an 8-year-old girl with isolated acute lupus pneumonitis as the initial presentation that required a lung biopsy for diagnosis. Although she had improvement with the administration of steroids, steroid treatment was reduced due to the drug's side effects resulting in the addition of azathioprine and mycophenolate mofetil to the treatment regimen. After the new regimen failed to result in clinical improvement, hydroxychloroquine treatment was started and a significant improvement was observed. Acute lupus pneumonitis is an uncommon manifestation of SLE and diagnosis may be difficult in patients without other organ involvement. PMID- 29589183 TI - New Diabetes Therapies and Diabetic Kidney Disease Progression: the Role of SGLT 2 Inhibitors. AB - PURPOSE OF REVIEW: Sodium-glucose co-transporter 2 (SGLT-2) inhibitors have emerged as a promising drug class for the treatment of diabetic kidney disease. Developed originally as glucose-lowering drugs by enhancing urinary glucose excretion, these drugs also lower many other renal and cardiovascular risk factors such as body weight, blood pressure, albuminuria, and uric acid. Results from the EMPA-REG OUTCOME and CANVAS trials show that these salutary effects translate into a reduction in cardiovascular outcomes and have the potential to delay the progression of kidney function decline. This review summarizes recent studies on the mechanisms and rationale of renoprotective effects. RECENT FINDINGS: Effects of SGLT-2 inhibitors on the kidney are likely explained by multiple pathways. SGLT-2 inhibitors may improve renal oxygenation and intra renal inflammation thereby slowing the progression of kidney function decline. Additionally, SGLT-2 inhibitors are associated with a reduction in glomerular hyperfiltration, an effect which is mediated through increased natriuresis and tubuloglomerular feedback and independent of glycemic control. Analogous to diabetic kidney disease, various etiologies of non-diabetic kidney disease are also characterized by single nephron hyperfiltration and elevated albuminuria. This offers the opportunity to reposition SGLT-2 inhibitors from diabetic to non diabetic kidney disease. Clinical trials are currently ongoing to characterize the efficacy and safety of SGLT-2 inhibitors in patients with diabetic and non diabetic kidney disease. The glucose-independent hemodynamic mechanisms of SGLT-2 inhibitors provide the possibility to extend the use of SGLT-2 inhibitors to non diabetic kidney disease. Ongoing dedicated trials have the potential to change clinical practice and outlook of high-risk patients with diabetic (and non diabetic) kidney disease. PMID- 29589184 TI - Controlled Versus Uncontrolled Resistant Hypertension: Are They in the Same Bag? AB - PURPOSE OF REVIEW: Resistant hypertension (RHTN) is a condition in which besides the antihypertensive therapy using at least three different drugs (including a diuretics), brachial blood pressure does not reach the target (e.g., 140/90 mmHg). RECENT FINDINGS: Despite the diversity of clinical presentations, we divide RHTN in two major groups according to blood pressure and number of drugs taken: controlled (C-RHTN) and uncontrolled (UC-RHTN) resistant hypertension, with refractory hypertension (RfHTN) included in the latter subgroup. Both C-RHTN and UC-RHTN are heterogenic and complex syndromes. To better approach this matter, the some pathophysiological mechanisms (increased volemia, hyperactivity, plasma cortisol, adipocitokines, and other pro-inflammatory factors), have a pivotal clinical role. Some features (African ethnic, obesity, age > 60, LV hypertrophy, and vascular stiffness) increase the risk of refractoriness as well as worst prognosis. Based on increased target organ damage, cardiovascular risk and events will be addressed in this review. Our conclusion is that although both C-RHTN and UC-RHTN are extreme phenotypes of hard-to-control BP, some mechanisms of the disease and clinical expressions are distinct. According to these differences, "UC-RHTN and C-RHTN are not in the same bag." PMID- 29589185 TI - Contemporary Management of Ulcerative Colitis. AB - PURPOSE OF REVIEW: We discuss the newest evidence-based data on management of ulcerative colitis (UC). We emphasize risk-stratification, optimizing medical therapies, and surgical outcomes of UC. RECENT FINDINGS: Recent medical advances include introduction of novel agents for UC. Vedolizumab, an anti-adhesion molecule, has demonstrated efficacy in moderate to severe UC. Tofacitinib, a small molecule, has also demonstrated efficacy. Data on optimization of infliximab show the superiority of combination therapy with azathioprine over monotherapy with infliximab or azathioprine alone. Data on anti-tumor necrosis factor-alpha (anti-TNF) therapeutic drug monitoring also hold promise, as do preliminary data on the dose escalation of infliximab in severe hospitalized UC. Surgical outcome data are reassuring, with new fertility data showing the effectiveness of in vitro fertilization. UC management is multi-disciplinary and changing. While novel therapies hold promise, better optimization of our current arsenal will also improve outcomes. PMID- 29589186 TI - Protective effects of mitochondrion-targeted peptide SS-31 against hind limb ischemia-reperfusion injury. AB - Hind limb ischemia-reperfusion injury is an important pathology in vascular surgery. Reactive oxygen species are thought to be involved in the pathogenesis of hind limb ischemia-reperfusion injury. SS-31, which belongs to a family of mitochondrion-targeted peptide antioxidants, was shown to reduce mitochondrial reactive oxygen species production. In this study, we investigated whether the treatment of SS-31 could protect hind limb from ischemia-reperfusion injury in a mouse model. The results showed that SS-31 treatment either before or after ischemia exhibited similar protective effects. Histopathologically, SS-31 treatment prevented the IR-induced histological deterioration compared with the corresponding vehicle control. SS-31 treatment diminished oxidative stress revealed by the reduced malondialdehyde level and increased activities and protein levels of Sod and catalase. Cellular ATP contents and mitochondrial membrane potential increased and the level of cytosolic cytC was decreased after SS-31 treatment in this IR model, demonstrating that mitochondria were protected. The IR-induced increase of levels of inflammatory factors, such as Tnf-alpha and Il-1beta, was prevented by SS-31 treatment. In agreement with the reduced cytosolic cytC, cleaved-caspase 3 was kept at a very low level after SS-31 treatment. Overall, the effect of SS-31 treatment before ischemia is mildly more effective than that after ischemia. In conclusion, our results demonstrate that SS-31 confers a protective effect in the mouse model of hind limb ischemia reperfusion injury preventatively and therapeutically. PMID- 29589188 TI - Spatial Visualization ability improves with and without studying Technical Drawing. AB - The results of several studies suggest that spatial ability can be improved through direct training with tasks similar to those integrated in the tests used to measure the ability. However, there is a greater interest in analyzing the effectiveness of indirect training such as games or of learning subjects that involve spatial processes to a certain extent. Thus, the objective of the present study was to analyze whether the indirect training in Technical Drawing improved the Spatial Visualization ability of Architecture students. For this purpose, a group of students enrolled in Fundamentals of Architecture were administered two tests, a Spatial Visualization task and an Abstract Reasoning task, at the beginning and the end of a semester, after having received training through the subjects "Technical Drawing I: Geometry and Perception" and "Projects I." The results of this group were compared with those of a control group of students enrolled in a Mathematics degree, who were also pre-post evaluated but had not received the training in Technical Drawing. The study showed a significant pre post improvement in both, Visualization and reasoning. However, this improvement occurred in both groups, thereby concluding that this improvement was not due to indirect training. Furthermore, no significant differences were found between men and women in any of the groups or conditions. These results clarify those of an earlier study where improvement in Visualization after training in Technical Drawing was found but did not include a comparison with a control condition. The control condition has proved to be important in order to consider the limitations of the effect of Technical Drawing on said improvement. PMID- 29589187 TI - Erythrocyte compression index is impaired in patients with residual vein obstruction. AB - Defective clot contraction has been postulated to contribute to thrombosis. We aimed to evaluate the association of residual vein obstruction (RVO) with erythrocyte compression within the whole-blood clot. We studied 32 patients with venous thromboembolism (VTE) taking vitamin K antagonists (VKAs) for at least 3 months (median time in therapeutic range 60%), including 12 (37.5%) with RVO, and 32 age- and sex-matched controls. In all study participants we evaluated whole blood clot retraction, expressed as the erythrocyte compression index (ECI), defined as a ratio of mean polyhedrocyte area to mean native erythrocyte area, along with clot area covered by polyhedrocytes, plasma clot permeability (Ks), clot lysis time (CLT), and thrombin generation. In both groups higher ECI, indicating impaired clot contraction, increased with older age, higher body mass index, red blood cell distribution width, and lower platelet count (all p < 0.05), but not with red blood cell count. In VTE patients ECI was 15.8% higher than in controls (median 63.6 vs. 54.9%, p = 0.021). Subjects with RVO had 20% higher ECI and 155% lower clot area covered by polyhedrocytes. RVO patients had also prolonged CLT by 41%, but not Ks, and elevated peak thrombin generation by 33%, as compared to those without RVO (all p < 0.05). This study is the first to show impaired compression of erythrocytes in RVO patients despite VKA anticoagulation. Altered ECI coexisted with hypolysability and increased thrombin generation. ECI might be useful in the diagnostic process of RVO or post thrombotic syndrome and can help optimize the anticoagulant therapy. PMID- 29589189 TI - Older adults show less interference from task-irrelevant social categories: evidence from the garner paradigm. AB - Though age-related difference in most cognitive performance has been found, there was no previous research examining age difference in multiple social categorizations. Using faces as stimuli and Garner Selective Attention Paradigm, this study explored the different characteristics of implicit and explicit social categorization between young and older adults. The results showed that young perceivers explicitly categorized gender and age of the faces faster and more readily than older perceivers did. When young adults judged specific category (gender category in Experiment 1; age category in Experiment 2), they were interfered from the completing irrelative category; however, irrelative category could not capture older adults' attention. These results first suggest perceivers' age indeed plays an important role in multiple social categorizations.

AB - The objective of this study was to investigate the possibility of modifying the growth trajectory in Raeini Cashmere goat breed. In total, 13,193 records on live body weight collected from 4788 Raeini Cashmere goats were used. According to Akanke's information criterion (AIC), the sing-trait random regression model included fourth-order Legendre polynomial for direct and maternal genetic effect; maternal and individual permanent environmental effect was the best model for estimating (co)variance components. The matrices of eigenvectors for (co)variances between random regression coefficients of direct additive genetic were used to calculate eigenfunctions, and different eigenvector indices were also constructed. The obtained results showed that the first eigenvalue explained 79.90% of total genetic variance. Therefore, changing the body weights applying the first eigenfunction will be obtained rapidly. Selection based on the first eigenvector will cause favorable positive genetic gains for all body weight considered from birth to 12 months of age. For modifying the growth trajectory in Raeini Cashmere goat, the selection should be based on the second eigenfunction. The second eigenvalue accounted for 14.41% of total genetic variance for body weights that is low in comparison with genetic variance explained by the first eigenvalue. The complex patterns of genetic change in growth trajectory observed under the third and fourth eigenfunction and low amount of genetic variance explained by the third and fourth eigenvalues. PMID- 29589192 TI - Utilization of Mucuna pruriens whole pods to feed lactating hair ewes. AB - Twenty nine Pelibuey * Katahdin hair ewes rearing single lamb were used during 42 days of lactation to evaluate the effect of including the Mucuna pruriens whole pods in the diets of lactating ewes on milk production and offspring performance. Animals were distributed at random into three experimental diets: a control diet without Mucuna (M0), and two more diets with the inclusion of 13 (M13) and 26% (M26), of milled pods of Mucuna pruriens, respectively. Dry matter intake, was not significantly different (P > 0.05) among diets. Milk yield (P > 0.05) was 734, 786, and 694 g/day for diets M0, M13, and M26, respectively. Milk fat (P > 0.05), milk protein (P > 0.05), and milk lactose (P > 0.05) did not differ between treatments. Lambs had similar daily weight gain (P > 0.05) among diets (180, 174, and 171 g/day for diets M0, M13, and M26, respectively). Diets with Mucuna whole pods were 5.6 and 12.9% more profitable (M13 and M26, respectively) than control diet. Under the conditions of this work, Mucuna pruriens whole pods can be included up to 26% in the diets of lactating crossbred hair ewes without negatively affecting their productive performance during the first 6 weeks of lactation. PMID- 29589193 TI - Spiral phyllotaxis underlies constrained variation in Anemone (Ranunculaceae) tepal arrangement. AB - Stabilization and variation of floral structures are indispensable for plant reproduction and evolution; however, the developmental mechanism regulating their structural robustness is largely unknown. To investigate this mechanism, we examined positional arrangement (aestivation) of excessively produced perianth organs (tepals) of six- and seven-tepaled (lobed) flowers in six Anemone species (Ranunculaceae). We found that the tepal arrangement that occurred in nature varied intraspecifically between spiral and whorled arrangements. Moreover, among the studied species, variation was commonly limited to three types, including whorls, despite five geometrically possible arrangements in six-tepaled flowers and two types among six possibilities in seven-tepaled flowers. A spiral arrangement, on the other hand, was unique to five-tepaled flowers. A spiral phyllotaxis model with stochasticity on initiating excessive primordia accounted for these limited variations in arrangement in cases when the divergence angle between preexisting primordia was less than 144 degrees . Moreover, interspecific differences in the frequency of the observed arrangements were explained by the change of model parameters that represent meristematic growth and differential organ growth. These findings suggest that the phyllotaxis parameters are responsible for not only intraspecific stability but interspecific difference of floral structure. Decreasing arrangements from six-tepaled to seven-tepaled Anemone flowers demonstrate that the stabilization occurs as development proceeds to increase the component (organ) number, in contrast from the intuition that the variation will be larger due to increasing number of possible states (arrangements). PMID- 29589194 TI - Understanding the role of floral development in the evolution of angiosperm flowers: clarifications from a historical and physico-dynamic perspective. AB - Flower morphology results from the interaction of an established genetic program, the influence of external forces induced by pollination systems, and physical forces acting before, during and after initiation. Floral ontogeny, as the process of development from a meristem to a fully developed flower, can be approached either from a historical perspective, as a "recapitulation of the phylogeny" mainly explained as a process of genetic mutations through time, or from a physico-dynamic perspective, where time, spatial pressures, and growth processes are determining factors in creating the floral morphospace. The first (historical) perspective clarifies how flower morphology is the result of development over time, where evolutionary changes are only possible using building blocks that are available at a certain stage in the developmental history. Flowers are regulated by genetically determined constraints and development clarifies specific transitions between different floral morphs. These constraints are the result of inherent mutations or are induced by the interaction of flowers with pollinators. The second (physico-dynamic) perspective explains how changes in the physical environment of apical meristems create shifts in ontogeny and this is reflected in the morphospace of flowers. Changes in morphology are mainly induced by shifts in space, caused by the time of initiation (heterochrony), pressure of organs, and alterations of the size of the floral meristem, and these operate independently or in parallel with genetic factors. A number of examples demonstrate this interaction and its importance in the establishment of different floral forms. Both perspectives are complementary and should be considered in the understanding of factors regulating floral development. It is suggested that floral evolution is the result of alternating bursts of physical constraints and genetic stabilization processes following each other in succession. Future research needs to combine these different perspectives in understanding the evolution of floral systems and their diversification. PMID- 29589196 TI - Debate: the per rectal/digital rectal examination exam in the emergency department, still best practice? AB - BACKGROUND: Emergency medicine practice in the UK and Ireland offers a junior and middle grade doctor great learning opportunities that force engagement with multiple specialties, life-saving procedures, exposure to a myriad of patient presentations, and opportunities for best practices in medicine. MAIN BODY: The emergency department (ED) can be a hectic and dynamic environment; communication from the ED to specialists is essential to ensure best clinical outcomes for patients. The "per rectal" (PR) or "digital rectal exam" (DRE) can be a very difficult diagnostic test for even the most skilled operator to discern pathological versus normal; we propose this is especially the case in the emergency department patient population. Some specialists require this exam performed by an unskilled junior doctor with varying results prior to reviewing a referred and sick patient. The PR/DRE benefits may be limited in the ED setting for some pathologies, and the result of the exam may have limited impact in the overall treatment plan in the ED. CONCLUSION: This short paper reviews the indications, benefits, shortfalls, and limitations of the PR/DRE in the emergency department setting and offers novel alternatives to maximize best practice, ensure best clinical outcomes for patients, and, to first, do no harm. PMID- 29589195 TI - Regulation of asymmetric polar auxin transport by PsPIN1 in endodermal tissues of etiolated Pisum sativum epicotyls: focus on immunohistochemical analyses. AB - This manuscript reports the production of specific polyclonal antibodies for PsPIN1, a putative auxin efflux carrier in Alaska pea (Pisum sativum L.) plants, and the cellular immunolocalization of PsPIN1. When pea seeds were set with the seed axis horizontal to the upper surface of a rockwool block, and allowed to germinate and grow for 3 days in the dark, the epicotyl grew upward. On the other hand, the application of 2,3,5-triiodobenzoic acid (TIBA) inhibited graviresponse. In the subapical epicotyl regions, PsPIN1 has been found to localize in the basal side of the plasma membrane of cells in endodermal tissues. Asymmetric PsPIN1 localization between the proximal and distal sides of the epicotyl was observed, the total amounts of PsPIN1 being more abundant in the proximal side. The asymmetric PsPIN1 distribution between the proximal and distal sides of the epicotyl was well correlated with unequal polar auxin transport as well as asymmetric accumulation of mRNA of PsPIN1 (Ueda et al. in Biol Sci Space 26:32-41, 2012; Ueda et al. in Plant Biol 16(suppl 1):43-49, 2014). In the proximal side of an apical hook, PsPIN1 localized in the basal side of the plasma membrane of cells in endodermal tissues, whereas in the distal side, the abundant distribution of PsPIN1 localized in the basal-lower (endodermal) side of the basal plasma membrane, suggesting possible lateral auxin movement from the distal side to the proximal side in this region. The application of TIBA significantly reduced the amount of PsPIN1 in the proximal side of epicotyls, but little in the distal side. These results suggest that unequal auxin transport in epicotyls during the early growth stage of etiolated pea seedlings is derived from asymmetric PsPIN1 localization in the apical hook and subapical region of epicotyls, and that asymmetric transport between the proximal and distal sides of epicotyls is required for the graviresponse of epicotyls.

PMID- 29589199 TI - Ditch network maintenance in peat-dominated boreal forests: Review and analysis of water quality management options. AB - The objective of this study was to evaluate the potential of different water management options to mitigate sediment and nutrient exports from ditch network maintenance (DNM) areas in boreal peatland forests. Available literature was reviewed, past data reanalyzed, effects of drainage intensity modeled, and major research gaps identified. The results indicate that excess downstream loads may be difficult to prevent. Water protection structures constructed to capture eroded matter are either inefficient (sedimentation ponds) or difficult to apply (wetland buffers). It may be more efficient to decrease erosion, either by limiting peak water velocity (dam structures) or by adjusting ditch depth and spacing to enable satisfactory drainage without exposing the mineral soil below peat. Future research should be directed towards the effects of ditch breaks and adjusted ditch depth and spacing in managing water quality in DNM areas.

AB - Although guidelines are available for hereditary hemochromatosis, a high percentage of the recommendations within them are not shared between the different guidelines. Our main aim is to provide an objective, simple, brief, and practical set of recommendations about therapeutic aspects of HFE hemochromatosis for p.Cys282Tyr (C282Y/C282Y) homozygous genotype, based on the published scientific studies and guidelines, in a form that is reasonably comprehensible to patients and people without medical training. This final version was approved at the Hemochromatosis International meeting on 12th May 2017 in Los Angeles. PMID- 29589200 TI - Molecular recognition of flunarizine dihydrochloride and beta-cyclodextrin inclusion complex by NMR and computational approaches. AB - BACKGROUND: Flunarizine dihydrochloride (FLN) is used in the prophylactic treatment of migraine, vertigo, occlusive peripheral vascular disease and epilepsy. Cyclodextrins (CDs) are chiral, truncated cone shaped macrocycles known for their inner hydrophobic and outer hydrophilic site. They form complexes with hydrophobic drug molecules and enhance the solubility and bioavailability of such compounds by enhancing drug permeability through mucosal tissues. NMR spectroscopy and computational docking have been recognized as an important tool for the interaction study of CDs-drug inclusion complexes in solution state. RESULTS: The structural assignments of FLN and beta-CD protons were determined by 1H NMR and 2D 1H-1H COSY NMR spectroscopy. 1H NMR spectroscopic studies of FLN, beta-CD and their mixtures confirmed the formation of beta-CD-FLN inclusion complex in solution. 1H NMR titration data for beta-CD-FLN inclusion complex showed 1:1 stoichiometry, an association constant of K a = 157 M-1 and change in Gibbs free energy of ?G = - 12.65 kJ mol-1. The binding constant of the beta-CD inclusion complex with two nearly similar structures, FLN and cetirizine dihydrochloride, were compared. Two-dimensional 1H-1H ROESY spectral data and molecular docking studies showed the modes of penetration of the aromatic rings from the wider rim side into the beta-CD cavity. The possible geometrical structures of the beta-CD-FLN inclusion complex have been proposed in which aromatic rings protrude close to the narrower rim of the beta-CD truncated cone. CONCLUSION: NMR spectroscopic studies of FLN, beta-CD and FLN:beta-CD mixtures confirmed the formation of 1:1 inclusion complex in solution at room temperature. Two-dimensional 1H-1H ROESY together with molecular docking study confirmed that the F-substituted aromatic ring of FLN penetrates into beta-CD truncated cone and the tail of aromatic rings were proximal to narrower rim of beta-CD. The splitting of aromatic signals of FLN in the presence of beta-CD suggests chiral differentiation of the guest FLN by beta-CD. PMID- 29589201 TI - The Potential Role of Toll-Like Receptor 4 in Mediating Dopaminergic Cell Loss and Alpha-Synuclein Expression in the Acute MPTP Mouse Model of Parkinson's Disease. AB - Toll-like receptors (TLRs) may have a role in Parkinson's disease (PD). In this study, we aimed at investigating the dopaminergic cell loss and alpha-synuclein (alpha-SYN) expression in TLR4-deficient mice (TLR4-/-) acutely exposed to 1 methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), a pharmacological PD model. TLR4 ablation restrained the number of dopaminergic neurons in the substantia nigra (SN), as assessed by tyrosine hydroxylase (TH) protein expression. Intriguingly, TLR4-/- mice showed massive alpha-SYN protein accumulation in the midbrain along with high alpha-SYN mRNA levels in cerebral cortex, striatum, hippocampus, and cerebellum. Contrary to expectations, the high levels of alpha SYN do not correlate with greater dopaminergic neuronal loss. The levels of nigral alpha-SYN protein in TLR4-/- mice further, but not significantly, increased during MPTP treatment. Contrariwise, MPTP treatment significantly induced the mRNA expression of alpha-SYN in examined brain regions of WT and TLR4 /- mice. Protein levels of GATA2, a transcription factor proposed to control alpha-SYN gene expression, did not change in TLR4-/- mice at baseline and after MPTP treatment. These findings suggest a role for TLR4 in mediating dopaminergic cell loss and in the constitutive expression of brain alpha-SYN. However, further exploration is needed in order to establish the actual role of alpha-SYN in the relative absence of TLR4. PMID- 29589202 TI - The Impact of Five VDR Polymorphisms on Multiple Sclerosis Risk and Progression: a Case-Control and Genotype-Phenotype Study. AB - Vitamin D receptor polymorphisms have been the target of many studies focusing on multiple sclerosis. However, previously reported results have been inconclusive. The objective of this study was to investigate the association between five vitamin D receptor polymorphisms (EcoRV, FokI, ApaI, TaqI, and BsmI) and multiple sclerosis susceptibility and its course. The study was carried out as a case control and genotype-phenotype study, consisted of 296 Czech multiple sclerosis patients and 135 healthy controls. Genotyping was carried out using polymerase chain reaction and restriction analysis. In multiple sclerosis men, allele and/or genotype distributions differed in EcoRV, TaqI, BsmI, and ApaI polymorphisms as compared to controls (EcoRV, pa = 0.02; Taq, pg = 0.02, pa = 0.02; BsmI, pg = 0.02, pa = 0.04; ApaI, pg = 0.008, pa = 0.005). In multiple sclerosis women, differences in the frequency of alleles and genotypes were found to be significant in ApaI (controls vs multiple sclerosis women: pg = 0.01, pa = 0.05). Conclusive results were observed between multiple sclerosis women in the case of EcoRV [differences in Expanded Disability Status Scale (p = 0.05); CT genotype was found to increase the risk of primary progressive multiple sclerosis 5.5 times (CT vs CC+TT pcorr = 0.01, sensitivity 0.833, specificity 0.525, power test 0.823)] and FokI [borderline difference in Multiple Sclerosis Severity Score (p = 0.05)]. Our results indicate that the distribution of investigated vitamin D receptor polymorphisms is a risk factor for multiple sclerosis susceptibility and progression in the Czech population. The association between disease risk and polymorphisms was found to be stronger in men. The association of disease progression with polymorphisms was observed only in women. PMID- 29589203 TI - Anabolic Therapy for the Treatment of Osteoporosis in Childhood. AB - PURPOSE OF REVIEW: Numerous forms of osteoporosis in childhood are characterized by low bone turnover (for example, osteoporosis due to neuromuscular disorders and glucocorticoid exposure). Anti-resorptive therapy, traditionally used to treat osteoporosis in the young, is associated with further reductions in bone turnover, raising concerns about the long-term safety and efficacy of such therapy. These observations have led to increasing interest in the role of anabolic therapy to treat pediatric osteoporosis. RECENT FINDINGS: While growth hormone and androgens appears to be relatively weak anabolic modulators of bone mass, emerging therapies targeting bone formation pathways (anti-transforming growth factor beta antibody and anti-sclerostin antibody) hold considerable promise. Teriparatide remains an attractive option that merits formal study for patients post-epiphyseal fusion, although it must be considered that adult studies have shown its effect is blunted when administered following bisphosphonate therapy. Mechanical stimulation of bone through whole body vibration therapy appears to be much less effective than bisphosphonate therapy for treating osteoporosis in children. New anabolic therapies which target important pathways in skeletal metabolism merit further study in children, including their effects on fracture risk reduction and after treatment discontinuation. PMID- 29589204 TI - New literacy challenge for the twenty-first century: genetic knowledge is poor even among well educated. AB - We live in an age of rapidly advancing genetic research. This research is generating new knowledge that has implications for personal health and well being. The present study assessed the level of genetic knowledge and personal engagement with genetics in a large sample (N = 5404) of participants. Participants received secondary education in 78 countries, with the largest samples from Russia, the UK and the USA. The results showed significant group differences in genetic knowledge between different countries, professions, education levels and religious affiliations. Overall, genetic knowledge was poor. The questions were designed to assess basic genetic literacy. However, only 1.2% of participants answered all 18 questions correctly, and the average score was 65.5%. Genetic knowledge was related to peoples' attitudes towards genetics. For example, those with greater genetic knowledge were on average more willing to use genetic knowledge for their personal health management. Based on the results, the paper proposes a number of immediate steps that societies can implement to empower the public to benefit from ever-advancing genetic knowledge. PMID- 29589206 TI - Saline-push improves rubidium-82 PET image quality. AB - INTRODUCTION: Rubidium-82 (82Rb) PET is used widely for myocardial perfusion imaging. The purpose of this study was to investigate if an additional saline push following the 82Rb elution improves PET image quality. METHODS: 82Rb PET scans were acquired with and without 26 mL saline-push in six patients as part of a clinical quality improvement program. Dynamic images were analyzed to measure the total activity delivered to the superior vena cava (SVC) and retained in the left ventricle (LV) myocardium. Tracer uptake images were used to measure blood background coefficient-of-variation (COV), myocardium-to-blood signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) to assess image quality. RESULTS: Similar eluted activity was measured with/without the saline-push (830 vs 795 MBq; P = 0.24). The activity delivered to the heart and retained in the myocardium was consistently increased more than twofold (SVC: + 114% and LV: + 104%; P < 0.001) with the saline-push. Image quality was improved in all patients, with lower background noise (COV: - 19%), higher SNR (+ 24%) and CNR (+ 27%) (all P <= 0.01). CONCLUSIONS: The saline-push used to flush 82Rb activity out of the infuser tubing, patient injection and intravenous access lines consistently increased the activity delivered to the heart by twofold. This technique is recommended to maximize image quality with 82Rb PET. PMID- 29589205 TI - Hyperchloraemia in sepsis. AB - Chloride represents-quantitatively-the most prevalent, negatively charged, strong plasma electrolyte. Control of chloride concentration is a probable major mechanism for regulating the body's acid-base balance and for maintaining homeostasis of the entire internal environment. The difference between the concentrations of chloride and sodium constitutes the major contributor to the strong ion difference (SID); SID is the key pH regulator in the body, according to the physicochemical approach. Hyperchloraemia resulting from either underlying diseases or medical interventions is common in intensive care units. Recent studies have demonstrated the importance of hyperchloraemia in metabolic acidosis and in other pathophysiological disorders present in sepsis. The aim of this narrative review is to present the current knowledge about the effects of hyperchloraemia, in relation to the underlying pathophysiology, in septic patients.

PMID- 29589208 TI - Significance of 11C-PIB PET/CT in cardiac amyloidosis compared with 99mTc aprotinin scintigraphy: A pilot study. AB - BACKGROUND: This study was to investigate the significance of 11C-Pittsburgh B (PIB) PET/CT in patients with suspected cardiac amyloidosis compared with 99mTc aprotinin scintigraphy. METHODS: Thirteen consecutive patients with suspected cardiac amyloidosis were considered for enrolment in this prospective pilot study. Participants were scheduled to undergo a series of 11C-PIB PET/CT and 99mTc-aprotinin within a 2-month period. Finally, we evaluated nine cases who underwent both imaging modalities, and compared imaging results with clinical and pathological results and prognosis. RESULTS: Six of the 9 patients who underwent both imaging modalities were diagnosed with amyloidosis, of whom 3 patients were diagnosed with cardiac amyloidosis from endomyocardial biopsy. These 3 patients with positive 11C-PIB uptake at the left ventricle wall showed worsening of cardiac function progressing in the short term or death caused by acute exacerbation of chronic heart failure. Six of 8 patients with positive uptake on 99mTc-aprotinin presented with amyloid deposition in the left ventricle wall, but symptoms remained stable if results of 11C-PIB were not positive. CONCLUSION: In a small sample of subjects, the present study showed that 11C-PIB accumulation in myocardium indicated cardiac amyloidosis with poor prognosis. Uptake of 11C-PIB may be related to progressive amyloid deposition to the heart and can predict patient prognosis. PMID- 29589209 TI - Nucleated red blood cells as predictors of mortality in patients with acute respiratory distress syndrome (ARDS): an observational study. AB - BACKGROUND: Nucleated red blood cells (NRBCs) in critically ill patients are associated with increased mortality and poor outcome. The aim of the present study was to evaluate the predictive value of NRBCs in patients with acute respiratory distress syndrome (ARDS). METHODS: This observational study was conducted at an ARDS referral center and included patients from 2007 to 2014. Daily NRBC counts were assessed and the predictive validity of NRBCs on mortality was statistically evaluated. A cutoff for prediction of mortality based on NRBCs was evaluated using ROC analysis and specified according to Youden's method. Multivariate nonparametric analysis for longitudinal data was applied to prove for differences between groups over the whole time course. Independent predictors of mortality were identified with multiple logistic and Cox' regression analyses. Kaplan-Meier estimations visualized the survival; the corresponding curves were tested for differences with the log-rank test. RESULTS: A total of 404 critically ill ARDS patients were analyzed. NRBCs were found in 75.5% of the patients, which was associated with longer length of ICU stay [22 (11; 39) vs. 14 (7; 26) days; p < 0.05] and higher mortality rates (50.8 vs. 27.3%; p < 0.001). Logistic regression analysis with mortality as response showed NRBC positivity per se to be an independent risk factor for mortality in ARDS with a doubled risk for ICU death (OR 2.03; 95% CI 1.16-3.55; p < 0.05). Also, NRBC value at ICU admission was found to be an independent risk factor for mortality (OR 3.25; 95% CI 1.09 9.73, p = 0.035). A cutoff level of 220 NRBC/ul was associated with a more than tripled risk of ICU death (OR 3.2; 95% CI 1.93-5.35; p < 0.0001). ARDS patients below this threshold level had a significant survival advantage (median survival 85 days vs. 29 days; log rank p < 0.001). Presence of a severe ARDS was identified as independent risk factor for the occurrence of NRBCs > 220/ul (OR 1.81; 95% CI 1.1-2.97; p < 0.05). CONCLUSIONS: NRBCs may predict mortality in ARDS with high prognostic power. The presence of NRBCs in the blood might be regarded as a marker of disease severity indicating a higher risk of ICU death.

AB - Emulsions made of oil, water and surfactants are widespread soft materials with complex structures depending on composition and temperature. Emulsion phase behavior at rest has been widely investigated but flow-induced effects, which are very relevant in many applications, can still be further explored towards improved emulsion microstructural design. In this work, we use low energy emulsification processing to create small-sized emulsions. In a previous report, we showed the emulsion morphology development and the effect of flow on the microstructure of a highly viscoelastic attractive emulsion which result in a concentrated nanoemulsion after viscoelastic droplet filaments are disrupted. Here, we show that upon stopping the flow, the filaments slowly buckle, recoil and finally form clusters of randomly flocculated droplets. We thus obtain two completely different emulsion morphologies simply induced by the action of flow, where in both cases attractive interactions play a key role. The emulsion high interfacial area represents a valuable feature for several applications such as upstream operations, microreaction media and drug delivery. PMID- 29589211 TI - A modified multi-patch technique for double-layered repair of ischemic posterior ventricular septal rupture. AB - BACKGROUND: The rupture of the posterior ventricular septum after acute inferior myocardial infarction is more challenging to repair than ruptures in other sites since it is less accessible and anatomically restricted. We described a modification of Daggett's original technique of multi-patch repair of ruptured posterior septum. CASE PRESENTATION: The technique was employed in the operation of a 67-year-old male who presented with severe heart failure at the 10th day after he developed inferior myocardial infarction. His ventricular septum had ruptured at the level between the posteromedial papillary muscle and the mitral annulus. A large endoventricular patch covered separately over the locally patched septal defect and the ventriculotomy defect which was going to be roofed eventually with an external patch. Both defects were then individually closed in double layers, holding a single continuous patch in common. The common use of a single patch expedited multilayered closure of the left ventricular defects and could minimize geometric remodeling of the covered area. The patches on both the endocardial and the epicardial sides avoided potentially fatal bleeding from the ventriculotomy site. The transmural mattress sutures incorporating ventriculotomy patches required minimal bites toward the posteromedial papillary muscle and mitral annulus, thereby preserving the mitral valve function. CONCLUSIONS: Thus, the technique enhances the advantage of the left ventriculotomy in the repair of posterior septal rupture and avoids ventriculotomy-related morbidity. PMID- 29589212 TI - Psychometric properties of the Satisfaction with Life Scale (SWLS), derived from a large German community sample. AB - PURPOSE: The aim of this study was to test psychometric properties of the Satisfaction with Life Scale (SWLS), to provide normative values, and to analyze associations between life satisfaction and sociodemographic and behavioral data. METHODS: A German community sample (n = 9711) with an age range of 18-80 years was surveyed using the SWLS and several other questionnaires. Confirmatory factor analysis (CFA) was used to test the dimensionality of the SWLS. Invariance across gender and age groups was tested with multiple-group CFA. Associations between SWLS, sociodemographic variables, and behavioral variables were tested with ANOVAs. RESULTS: Confirmatory factorial analysis results confirmed that the SWLS is a one-dimensional scale. Measurement invariance across gender was completely confirmed, while concerning age strict measurement invariance was confirmed. The effects of gender and age on satisfaction with life were weak. Satisfaction with life was associated with fatigue (r = - .49), the mental component of quality of life (r = .45), anxiety (r = - .42), dispositional optimism (r = .41), pessimism (r = - .34), sleep quality (r = - .32), and sociodemographic factors such as marital status, income, and occupational status. Non-smokers reported higher life satisfaction than smokers. CONCLUSIONS: Because of the good psychometric properties, the SWLS can be recommended for use in epidemiological research. Normative values based on a large community sample are provided. PMID- 29589213 TI - Effects of Some Growth Factors and Cytokines on the Expression of the Repair Enzyme MGMT and Protein MARP in Human Cells In Vitro : Effect of Some Growth Factors and Cytokines. AB - The inducible repair enzyme O6-methylguanine-DNA methyltransferase (MGMT) eliminates O6-methylguanine adducts in DNA and protects the cells from damaging effects of alkylating agents. We have found that anti-MGMT antibodies recognize both the MGMT protein with a mol. weight ~ 24 kDa and a protein with a mol. weight ~ 48 kDa, which was named MARP (anti-methyltransferase antibody recognizable protein). A number of growth factors and cytokines were shown to regulate the expression of MGMT and MARP proteins. The ranges of concentrations of several growth factors and cytokines that caused increasing or decreasing protein amounts in human cell cultures were determined. The results of special biological experiments have allowed us to assume a possible role of MARP in the repair of alkyl adducts in human cells. PMID- 29589214 TI - Association of Tumor Necrosis Factor Alpha-Induced Protein 3 Interacting Protein 1 (TNIP1) Gene Polymorphism (rs7708392) with Lupus Nephritis in Egyptian Patients. AB - Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Previous studies suggest that mutant A20 binding inhibitor of NF-kappaB 1 (ABIN1) protein encoded by tumor necrosis factor alpha induced protein 3 interacting protein 1 (TNIP1) gene is associated with LN via NF kappaB dysregulation. The aim of the current study was to evaluate the association of TNIP1 gene SNP rs7708392 with SLE and LN in Egyptian patients. 5' nuclease Allelic discrimination was used to evaluate the frequency of TNIP1 SNP rs7708392 in 53 patients with LN, 57 SLE patients without nephritis and 85 healthy controls. The genotyping analysis revealed that the CC genotype was more frequent in controls than SLE patients, while GC and GG genotypes were more common in SLE patients. Moreover, the GG genotype and the G allele were significantly more prevalent among LN patient than non-LN patients (P < 0.001). In LN patients, the most common genotype was GG (56.6%), while among the non-LN patients; the CG genotype was the most common (59.6%). Regression analysis demonstrated that SLE patients carrying only one G allele had a 3.4 folds increased risk for LN. Our results suggested that TNIP1 SNP (rs7708392) might be associated with the LN in Egyptian SLE patients. TNIP1 SNP (rs7708392) might be used to identify patients at risk of developing LN, which could help in early detection and treatment before progression to end-stage renal disease, improving patients' outcome and quality of life. PMID- 29589215 TI - Cellular Glucose Uptake During Breath-Hold Diving in Experienced Male Breath-Hold Divers. AB - BACKGROUND: The physiological and pathophysiological mechanisms that govern diving, both self-contained underwater breathing apparatus (SCUBA) and breath hold diving (BH-diving), are in large part well known, even if there are still many unknown aspects, in particular about cell metabolism during BH-diving. The scope of this study was to investigate changes in glycemia, insulinemia, and the catecholamine response to BH-diving, to better understand if the insulin stimulated glucose uptake mechanism is involved in cellular metabolism in this sport. METHODS: Twenty male experienced healthy breath-hold divers were studied. Anthropometric information was obtained. Glycemia, insulinemia, and catecholamine response were investigated before and after the series of BH-diving. RESULTS: We found a statistically significant decrease in the blood glucose levels between before and after dives (mean 94.3 +/- 11.6 vs. 83.5 +/- 12.5 mg/dl) P = 0.001 and a statistically significant increase in blood insulin value (median 4.5 range 3.4/6.4 vs. 7.0 range 4.2/10.2 mcgU/ml) P < 0.0001. Also, we found a statistically significant increase of catecholamine production (median 14.0 range 8/18 vs. 15.5 range 10.0/21.0 MUg) P < 0.0001. CONCLUSIONS: The increase in blood insulin during BH-diving associated with the decrease of blood glucose levels could indicate that the upregulating cellular uptake is not caused by activation of the specific glucose transporters. Particular diving-related conditions such as the diving reflex, the intermittent hypoxia/hyperoxia, and the particular environmental condition could play an important role in the mechanism involved in glycemia decrease in BH-diving. Our data confirm that the adaptations to BH diving are caused by complex mechanisms and involve many peculiar responses still in large part unknown. PMID- 29589216 TI - Vernier But Not Grating Acuity Contributes to an Early Stage of Visual Word Processing. AB - The process of reading words depends heavily on efficient visual skills, including analyzing and decomposing basic visual features. Surprisingly, previous reading-related studies have almost exclusively focused on gross aspects of visual skills, while only very few have investigated the role of finer skills. The present study filled this gap and examined the relations of two finer visual skills measured by grating acuity (the ability to resolve periodic luminance variations across space) and Vernier acuity (the ability to detect/discriminate relative locations of features) to Chinese character-processing as measured by character form-matching and lexical decision tasks in skilled adult readers. The results showed that Vernier acuity was significantly correlated with performance in character form-matching but not visual symbol form-matching, while no correlation was found between grating acuity and character processing. Interestingly, we found no correlation of the two visual skills with lexical decision performance. These findings provide for the first time empirical evidence that the finer visual skills, particularly as reflected in Vernier acuity, may directly contribute to an early stage of hierarchical word processing. PMID- 29589217 TI - Identification and characterization of inorganic-phosphate-solubilizing bacteria from agricultural fields with a rapid isolation method. AB - The ability to solubilize fixed inorganic phosphorus (P) for plant growth is important for increasing crop yield. More P can be released by inoculating soil with inorganic-phosphate-solubilizing bacteria (iPSBs). We used 96-well microplates instead of traditional 200-mm petri dishes to rapidly screen iPSB strains for their solubilizing ability. We simultaneously obtained 76 iPSB isolates from 576 wells containing two agricultural soils. This method conveniently identified positive iPSB strains and effectively prevented fungal cross-contamination. Maximum-likelihood phylogenetic trees of the isolated strains showed that Bacillus megaterium was the most dominant iPSB, and strains Y99, Y95, Y924 and Y1412 were selected as representatives for the analysis of P solubilization. Succinic acid was the main organic acid of B. megaterium for releasing P. It was strongly correlated with the increase in soluble P concentration during 168 h of incubation of these four strains. pH was negatively exponentially correlated with the amount of soluble P in the medium, and the amount of succinic acid was strongly linearly correlated with the amount of P released (P < 0.001), suggesting that organic acid may mobilize microbial P. Our study provides an efficient and effective method for identifying and analyzing the growth of iPSB strains able to solubilize inorganic P and gives a better understanding of the mechanism of P solubilization. PMID- 29589218 TI - Mental Health Attitudes and Beliefs in a Community Sample on the Central Coast in Australia: Barriers to Help Seeking. AB - There continues to be call for greater community awareness actions and strategies to reduce stigma and enhance mental health literacy nationally and internationally. To identify local barriers to help-seeking and perceptions around stigma, we developed a 'mental health attitudes and beliefs' survey which was administered at a range of community events on the Central Coast in New South Wales, Australia. The aim was for the results of this survey to inform the development of strategies that enhance local help-seeking behaviours that are sensitive to the role of age, gender and Indigenous status. People who approached our Mental Health Information stall were invited to complete the survey and 282 individuals completed the survey. The data was analysed descriptively with a focus on comparing subgroups based on age, gender, Indigenous status, and previous service access or experience of mental illness. Cost, stigma and mental health literacy were found to be prominent barriers to help-seeking for the overall cohort; however, the ways in which or extent to which these barriers impact on help seeking varied between subgroups. A discussion of these differences and their implications for practice is the focus of this paper. PMID- 29589219 TI - Risk Factors for Suicide in Older Inpatient Veterans with Schizophrenia. AB - Patients with schizophrenia have an elevated risk of suicidal behavior. We explored whether there were age differences in inpatients with schizophrenia admitted for suicidal behavior. We compared demographic/clinical characteristics of 76 inpatients aged > 59 to those < 60. All patients had a score greater > 0 on items 4 (active suicidality) and/or 5 (passive suicidality) on the Beck Scale for Suicidal Ideation for inclusion. There were no significant group differences with respect to race, education, depressive symptoms or negative symptoms. There was evidence suggesting that hallucinations appear to be less prominent in the older group. Future studies will determine whether these age related differences are stable over time and could account for potential age differences in suicidal behavior in individuals with schizophrenia. PMID- 29589220 TI - Ocular involvement in melioidosis: a 23-year retrospective review. AB - BACKGROUND: Ocular involvement in melioidosis is rare and has devastating outcomes. Although there have been few reports on the condition, Khon Kaen, a city in northeast Thailand, has been called the "capital of melioidosis" due to the high prevalence of the condition in the region. We retrospectively reviewed all admitted cases of melioidosis with ocular involvement from the two largest hospitals in Khon Kaen. We reviewed cases from Srinagarind Hospital (a university hospital) of patients admitted between 1993 and 2016 and from Khon Kaen Hospital (a provincial hospital) of patients who presented from 2012 to 2016. RESULTS: We identified 16 cases of ocular involvement. Eight of these cases were proven from positive culture, and the remaining eight were implied from high melioidosis titer. The prevalence was estimated as being from 0.49 to 1.02%. Most patients had underlying diseases (14, 88%), of which diabetes mellitus was the most prevalent (12, 75%). Nine cases (56%) were part of disseminated septicemia. Patients suffered from blindness in 11 (73%) of the 15 cases in which visual acuity was recorded. Orbital cellulitis was the most common manifestation (7, 44%) followed by endophthalmitis (4, 25%). Interestingly, all patients with necrotizing fasciitis (100%) developed septic shock as a consequence. In most of the cases, patients underwent surgery (13, 81%) including incision and drainage, debridement, and pars plana vitrectomy. Despite appropriate management, the visual outcomes were disappointing (9, 64%). CONCLUSION: To summarize, ocular melioidosis is a highly destructive disease. Early detection and prompt surgical management may reduce morbidity and mortality from septic shock. PMID- 29589221 TI - Long-term survival with repeat resection for lung oligometastasis from pancreatic ductal adenocarcinoma: a case report. AB - BACKGROUND: Long-term survival after resection of metastases from pancreatic ductal adenocarcinoma is rare. CASE PRESENTATION: A 54-year-old man underwent pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) with UICC staging pT3N1M0 followed by adjuvant chemotherapy with gemcitabine (GEM). Three years after radical resection of the primary tumor, a tiny nodule was found in the lower lobe of the left lung. Despite treatment with GEM, it increased gradually, but no other metastases were found. Eighteen months after the first indication of the nodule, wedge resection was performed. Pathological examination of the nodule indicated a metastatic tumor from PDAC. Pulmonary metastasectomy was again performed for lung oligometastases at 77 and 101 months after PD. The patient has been asymptomatic without tumor recurrence for 4 years since the last pulmonary resection. CONCLUSIONS: In PDAC, the treatment strategy for oligometastasis is controversial. However, a few cases of long-term survival after pulmonary metastasectomy for oligometastasis of PDAC have been reported. More such cases need to be studied to address this issue effectively. PMID- 29589222 TI - Development of Novel Octanoyl Chitosan Nanoparticles for Improved Rifampicin Pulmonary Delivery: Optimization by Factorial Design. AB - A novel hydrophobic chitosan derivative, octanoyl chitosan (OC) with improved organic solubility was synthesized, characterized, and employed for the preparation of rifampicin (Rif) encapsulated nanoparticle formulations for pulmonary delivery. OC was characterized to confirm acyl group substitution and cytotoxicity in A549 epithelial lung cells. OC nanoparticles were produced by the double emulsion solvent evaporation technique without cross-linking and characterized for particle size distribution, morphology, crystallinity, thermal stability, aerosol delivery, and drug release rate. OC was successfully synthesized with substitution degree of 44.05 +/- 1.75%, and solubility in a range of organic solvents. Preliminary cytotoxicity studies of OC showed no effect on cell viability over a period of 24 h on A549 cell lines. OC nanoparticles were optimized using a 32 full factorial design. An optimized batch of OC nanoparticles, smooth and spherical in morphology, had mean hydrodynamic diameter of 253 +/- 19.06 nm (PDI 0.323 +/- 0.059) and entrapment efficiency of 64.86 +/- 7.73% for rifampicin. Pulmonary deposition studies in a two-stage impinger following aerosolization of nanoparticles from a jet nebulizer gave a fine particle fraction of 43.27 +/- 4.24%. In vitro release studies indicated sustained release (73.14 +/- 3.17%) of rifampicin from OC nanoparticles over 72 h, with particles demonstrating physical stability over 2 months. In summary, the results confirmed the suitability of the developed systems for pulmonary delivery of drugs with excellent aerosolization properties and sustained-release characteristics. PMID- 29589223 TI - An Analysis of the Inclusion of Medications Considered Potentially Inappropriate in Older Adults in Chemotherapy Templates for Hematologic Malignancies: One Recommendation for All? AB - BACKGROUND: There remains a paucity of data regarding the use of potentially inappropriate medications (PIMs) in the supportive management of older adults undergoing chemotherapy. Raising awareness among healthcare providers regarding the frequency of their use and potential toxicities may help to minimize the risks to patients. OBJECTIVE: The aim of this study was to evaluate the frequency of six specific classes of medications considered PIMs by the American Geriatrics Society Beers Criteria that are commonly included in the National Comprehensive Cancer Network (NCCN) chemotherapy order templates for hematologic malignancies. The six PIMs evaluated are first-generation antihistamines, benzodiazepines, corticosteroids, H2-receptor antagonists, metoclopramide, and antipsychotics. METHODS: A total of 311 unique chemotherapy order templates published online by the NCCN for the treatment of hematologic malignancies were reviewed to determine the frequency that these six specific PIMs were recommended for supportive care. RESULTS: Approximately 45% of the NCCN chemotherapy templates for hematologic malignancies specifically recommended the use of at least one of the six PIMs examined. The remainder of the templates evaluated referred exclusively to the NCCN Guidelines(r) on Oncology for Antiemesis, which also included the use of at least one of the six PIMs evaluated. CONCLUSIONS: These findings demonstrate that PIMs are frequently used as supportive therapy in the treatment of hematologic malignancies. Increasing healthcare provider awareness of their potential side effects may minimize the risks associated with their use in older adults with hematologic malignancies undergoing chemotherapy. PMID- 29589224 TI - Comparison of three-parameter kinetic model analysis to standard Patlak's analysis in 18F-FDG PET imaging of lung cancer patients. AB - BACKGROUND: Patlak's graphical analysis can provide tracer net influx constant (Ki) with limitation of assuming irreversible tracer trapping, that is, release rate constant (kb) set to zero. We compared linear Patlak's analysis to non linear three-compartment three-parameter kinetic model analysis (3P-KMA) providing Ki, kb, and fraction of free 18F-FDG in blood and interstitial volume (Vb). METHODS: Dynamic PET data of 21 lung cancer patients were retrospectively analyzed, yielding for each patient an 18F-FDG input function (IF) and a tissue time-activity curve. The former was fitted with a three-exponentially decreasing function, and the latter was fitted with an analytical formula involving the fitted IF data (11 data points, ranging 7.5-57.5 min post-injection). Bland Altman analysis was used for Ki comparison between Patlak's analysis and 3P-KMA. Additionally, a three-compartment five-parameter KMA (5P-KMA) was implemented for comparison with Patlak's analysis and 3P-KMA. RESULTS: We found that 3P-KMA Ki was significantly greater than Patlak's Ki over the whole patient series, + 6.0% on average, with limits of agreement of +/- 17.1% (95% confidence). Excluding 8 out of 21 patients with kb > 0 deleted this difference. A strong correlation was found between Ki ratio (=3P-KMA/Patlak) and kb (R = 0.801; P < 0.001). No significant difference in Ki was found between 3P-KMA versus 5P-KMA, and between 5P-KMA versus Patlak's analysis, with limits of agreement of +/- 23.0 and +/- 31.7% (95% confidence), respectively. CONCLUSIONS: Comparison between 3P-KMA and Patlak's analysis significantly showed that the latter underestimates Ki because it arbitrarily set kb to zero: the greater the kb value, the greater the Ki underestimation. This underestimation was not revealed when comparing 5P-KMA and Patlak's analysis. We suggest that further studies are warranted to investigate the 3P-KMA efficiency in various tissues showing greater 18F-FDG trapping reversibility than lung cancer lesions. PMID- 29589225 TI - Low concordance between surgical and radiological assessment of degree of resection and treatment-related hypothalamic damage: results of KRANIOPHARYNGEOM 2007. AB - BACKGROUND: Assessment of presurgical hypothalamic involvement (psHI) and treatment-related hypothalamic damage (trHD) is relevant for the decision on risk adapted treatment and rehabilitation strategies in craniopharyngioma. PATIENTS AND METHODS: 129 surgical reports of childhood-onset craniopharyngioma patients recruited 2007-2014 in KRANIOPHARYNGEOM 2007 were analyzed. Data on psHI were available based on surgeon's (63%), reference neuroradiologist's (95%), and local radiologist's (23%) assessment. The surgical degree of resection (DoR) was assessed by neurosurgeon (95%), reference neuroradiologist (73%), and local radiologist (61%). TrHD was assessed by neurosurgeon (33%), by reference neuroradiologist (95%), and by local radiologist (2%). Neurosurgical center size was categorized based on patient load. RESULTS: Surgical assessments on psHI (n = 78), DoR (n = 89) and trHD (n = 42) as documented in surgical reports could be compared with the assessment of respective parameters by reference neuroradiologist. Differences with regard to DoR (p = 0.0001) and trHD (p < 0.0001) were detectable between surgeon's and reference neuroradiologist's assessment, whereas psHI was assessed similarly. Concordance for DoR and trHD was observed in 48 and 62%, respectively. Surgeons estimated a higher rate of complete resections and a lower rate of trHD. Neuroradiological reference assessment of trHD had higher predictive value for hypothalamic sequelae then surgical assessment. Observed differences were not related to neurosurgical center size. CONCLUSIONS: Observed differences between surgical and neuroradiological estimation of risk factors in craniopharyngioma support the necessity of neuroradiological reference review to assure standards of quality. This could be established by central internet-based neuroradiological review in KRANIOPHARYNGEOM 2007. Standardization of surgical reports including specific assessment of tumor/damage location is recommended. PMID- 29589227 TI - Morphological reflections of evolutionary adaptations in the tongue of the white headed duck. AB - During an organism's evolution, functional adaptations help species to become better suited to their ecological niches. From the morphological aspect, these adaptations are reflected in the anatomical specializations of different organs. Specializations of the lingual organ is a critical adaptation of birds, such as the white-headed duck (Oxyura leucocephala), that enables their nutritional requirements to be met. For optimal use of the available food resources, the white-headed duck utilizes three methods of food collection, namely pecking, grazing and filter-feeding. Since this species is classified as endangered, we conducted the present study on two carcasses of the white-headed duck (death due to natural causes) employing routine histological methods, light microscopy and scanning electron microscopy. Our results show that the tongue of this bird shares some similarities and some differences with the tongue of other members of the family Anatidae. The results confirm that it is better adapted to the filter feeding method rather than to other types of food intake. This adaptation is reflected by anatomical specializations of its lingual structures, including the stair-like outline shape, bi-sectional lingual body, a deep median sulcus, lateral conical papillae, mucus secreting glands, lack of serous secreting glands, cartilaginous skeleton and the triangular fibromuscular structure of the lingual body. The so-called triangular structure and cartilaginous skeleton are the major structures involved in the lingual motions during the filter-feeding method. The presence of the triangular structure and its connection with the cartilaginous skeleton and lingual mucosa have not previously been reported in any species of birds. PMID- 29589226 TI - Sedentary behaviour and risk of all-cause, cardiovascular and cancer mortality, and incident type 2 diabetes: a systematic review and dose response meta analysis. AB - PURPOSE: To estimate the strength and shape of the dose-response relationship between sedentary behaviour and all-cause, cardiovascular disease (CVD) and cancer mortality, and incident type 2 diabetes (T2D), adjusted for physical activity (PA). Data Sources: Pubmed, Web of Knowledge, Medline, Embase, Cochrane Library and Google Scholar (through September-2016); reference lists. Study Selection: Prospective studies reporting associations between total daily sedentary time or TV viewing time, and >= one outcome of interest. Data Extraction: Two independent reviewers extracted data, study quality was assessed; corresponding authors were approached where needed. Data Synthesis: Thirty-four studies (1,331,468 unique participants; good study quality) covering 8 exposure outcome combinations were included. For total sedentary behaviour, the PA adjusted relationship was non-linear for all-cause mortality (RR per 1 h/day: were 1.01 (1.00-1.01) <= 8 h/day; 1.04 (1.03-1.05) > 8 h/day of exposure), and for CVD mortality (1.01 (0.99-1.02) <= 6 h/day; 1.04 (1.03-1.04) > 6 h/day). The association was linear (1.01 (1.00-1.01)) with T2D and non-significant with cancer mortality. Stronger PA-adjusted associations were found for TV viewing (h/day); non-linear for all-cause mortality (1.03 (1.01-1.04) <= 3.5 h/day; 1.06 (1.05-1.08) > 3.5 h/day) and for CVD mortality (1.02 (0.99-1.04) <= 4 h/day; 1.08 (1.05-1.12) > 4 h/day). Associations with cancer mortality (1.03 (1.02-1.04)) and T2D were linear (1.09 (1.07-1.12)). CONCLUSIONS: Independent of PA, total sitting and TV viewing time are associated with greater risk for several major chronic disease outcomes. For all-cause and CVD mortality, a threshold of 6-8 h/day of total sitting and 3-4 h/day of TV viewing was identified, above which the risk is increased. PMID- 29589228 TI - Parental Wellbeing, Parenting and Child Development in Ghanaian Families with Young Children. AB - Approximately one-third of early childhood pupils in Ghana are struggling with meeting basic behavioral and developmental milestones, but little is known about mechanisms or factors that contribute to poor early childhood development. With a lack of developmental research to guide intervention or education program and policy planning, this study aimed to address these research gaps by examining a developmental mechanism for early childhood development. We tested a mediational mechanism model that examined the influence of parental wellbeing on parenting and children's development. Two hundred and sixty-two Ghanaian parents whose children attended early childhood classes (nursery to 3rd grade) were recruited. Data were gathered through parent interviews and Structural Equation Modeling was utilized to examine pathways of the model. Results support the mediational model that Ghanaian parents' depression was associated with less optimal parenting, and in turn greater child externalizing behavioral problems. This study adds new evidence of cross cultural consistency in early childhood development. PMID- 29589229 TI - Humanized Mouse Models for the Preclinical Assessment of Cancer Immunotherapy. AB - Immunotherapy is one of the most exciting recent breakthroughs in the field of cancer treatment. Many different approaches are being developed and a number have already gained regulatory approval or are under investigation in clinical trials. However, learning from the past, preclinical animal models often insufficiently reflect the physiological situation in humans, which subsequently causes treatment failures in clinical trials. Due to species-specific differences in most parts of the immune system, the transfer of knowledge from preclinical studies to clinical trials is eminently challenging. Human tumor cell line-based or patient-derived xenografts in immunocompromised mice have been successfully applied in the preclinical testing of cytotoxic or molecularly targeted agents, but naturally these systems lack the human immune system counterpart. The co transplantation of human peripheral blood mononuclear cells or hematopoietic stem cells is employed to overcome this limitation. This review summarizes some important aspects of the different available tumor xenograft mouse models, their history, and their implementation in drug development and personalized therapy. Moreover, recent progress, opportunities and limitations of different humanized mouse models will be discussed. PMID- 29589231 TI - Epibulbar osseous choristoma: a photo essay case report. AB - PURPOSE: To present the pre-, per- and postoperative features of epibulbar osseous choristoma. METHODS: Case description including intraoperative imaging and histopathology. RESULTS: A 32-year-old male patient presented with a lesion on his right eye, suggestive of an epibulbar dermolipoma. Excision of bony lesion was performed and revealed epibulbar osseous choristoma. CONCLUSIONS: Epibulbar osseous choristoma is a rare and benign condition which can present with features similar to dermolipoma. PMID- 29589230 TI - Benefit Versus Risk Assessment of Rotavirus Vaccination in France: A Simulation and Modeling Analysis. AB - INTRODUCTION: Two vaccines against rotavirus gastroenteritis (RVGE) in young children, Rotarix and RotaTeq, have been available in Europe since 2006. Vaccination against rotaviruses significantly reduces the burden of RVGE, but it is also associated with a very small increased risk of intussusception. In a benefit-risk analysis, the prevented RVGE burden is weighed against the possible excess of intussusception. PURPOSE: The aim was to compare the estimated benefits and risks of Rotarix vaccination in France. METHODS: We estimated the benefits (vaccine-preventable RVGE hospitalizations and deaths) and risks (vaccine-caused intussusception hospitalizations and deaths) following two doses of Rotarix in a birth cohort of 791,183 followed for 3-5 years in France. We used data from peer reviewed clinical and epidemiological studies or publications, and government statistics. RESULTS: Within the total number of French children below 5 years of age, we estimate vaccination could prevent a median 11,132 [95% credible interval (CI) 7842-14,408] RVGE hospitalizations and 7.43 (95% CI 3.27-14.68) RVGE deaths. At the same time, vaccination could cause an average of 6.86 (95% CI 2.25-38.37) intussusception hospitalizations and 0.0099 (95% CI 0.0024-0.060) intussusception deaths in the entire French birth cohort of infants below 1 year of age. Therefore, for every intussusception hospitalization and every intussusception death caused by vaccination, 1624 (95% CI 240-5243) RVGE hospitalizations and 743 (95% CI 93-3723) RVGE deaths are prevented, respectively, by vaccination. CONCLUSIONS: The vaccine-prevented RVGE hospitalizations and deaths (benefit) greatly outweigh the excess potentially vaccination-related cases of intussusception (risk), indicating a favorable benefit-risk balance for Rotarix in France. PMID- 29589232 TI - Autologous neurosensory retinal free patch transplantation for persistent full thickness macular hole. AB - PURPOSE: To evaluate anatomical and functional outcomes after autologous neurosensory retinal free patch (ANRFP) transplantation for persistent idiopathic full-thickness macular hole (iFTMH). METHODS: A 65-year-old woman with persistent macular hole in her right eye after previous 27-gauge pars plana vitrectomy with internal limiting membrane peeling and long-acting gas tamponade underwent ANRFP transplantation. Before surgery, best corrected visual acuity in her right eye was 20/800. Optical coherence tomography (OCT) showed a 715-micron-diameter FTMH. To treat the persistent FTMH, a small autologous neurosensory retinal patch was transplanted and placed inside the macular hole under perfluorocarbon liquids (PFCL). PFCL-air exchange was performed, and long-acting gas tamponade was carried out. Clinical features of the macular area, visual acuity (VA), fundus autofluorescence, microperimetry and OCT were recorded during the 10-month follow up. RESULTS: The macular hole appeared successfully closed with retinal patch stable and well plugged into the hole during the whole follow-up. VA improved to 20/100 and microperimetry revealed an increase in mean retinal sensitivity from 14.7 dB at 1 month to 15.6 dB at 10 months postoperatively. OCT showed a well distinguishable retinal patch into the hole 1 month after surgery and a completely integrated retinal patch between the retinal layers 10 months postoperatively. No intra- and postoperative complications were noticed. CONCLUSIONS: ANRFP transplantation may represent an innovative technique for persistent iFTMH treatment.

AB - While essential to food production, nitrogen (N) fertilizers in agricultural ecosystems are also important sources of environmental pollution nationally and globally. The environmental impact of three N fertilization levels (30, 60, and 90 kg ha-1) plus a non-N control (0 kg ha-1) in growing three rice cultivars (cv. Hashemi, cv. Alikazemi, and cv. Khazar) were assessed for 2 years in northern Iran, with the methodology of the life cycle assessment (LCA). The impact categories evaluated in this study were global warming, acidification, terrestrial eutrophication, and depletion of fossil, phosphate, and potassium resources. Over cultivars, no use of N fertilizer provided the lowest grain yield (2194 kg ha-1), whereas the N rates of 60 and 90 kg ha-1 increased grain yield by 52.9 and 66.9%, respectively. Over N rates, cv. Khazar produced the highest grain yield (3415 kg ha-1) and cv. Hashemi the lowest (2663 kg ha-1). On-farm (foreground) emissions were higher than off-farm (background) emissions in most impact categories. The maximum value of environmental index (1.33) was observed for cv. Hashemi with 90 kg N ha-1, while the minimum value (0.38) was observed for cv. Khazar without N fertilization. Moreover, cv. Khazar showed the lowest resource depletion index (0.44) with 90 kg N ha-1, whereas cv. Hashemi with no use of N showed the maximum value (0.96). Over cultivars, high N rates imposed drastic impact to the categories acidification and terrestrial eutrophication. However, selection of high-yielding cultivars significantly alleviated the impact to most categories. Fertilization that enables optimal yields, in accordance with the nutrient requirements of crops, ensures the most efficient land use and sustainable rice production. PMID- 29589234 TI - Nitrogen fertilizer in combination with an ameliorant mitigated yield-scaled greenhouse gas emissions from a coastal saline rice field in southeastern China. AB - Coastal saline rice fields play an increasingly important role in rice production and associated greenhouse gas (GHG) emissions. However, few studies investigated the influences of nitrogen (N) fertilizer and soil ameliorant on GHG emissions simultaneously in this region. Thus, a field experiment was established to study the effects of different N fertilizers and soil ameliorant on global warming potential (GWP) and yield-scaled GHG intensity (GHGI) after accounting for carbon dioxide (CO2) equivalent emissions of methane (CH4) and nitrous oxide (N2O), agrochemical inputs, and farm operations along with agronomic nitrogen use efficiency (NUE) during the rice season of 2016 in a coastal saline paddy in Lianyungang, China. The experiment was initiated with four N treatments (N0, no N; Nu, urea; Nm, organic-inorganic mixed fertilizer; Nw, organic fertilizer made from wheat straw) and two ameliorant (A) treatments (A0, no ameliorant; A1, 22.5 kg ha-1 ameliorant). The results showed that three N fertilizers significantly increased the CH4 emissions, N2O emissions, GWP, and grain yield by 42.2% (p < 0.001), 57.1% (p < 0.001), 49.8% (p < 0.001), and 58.9% (p < 0.001), respectively. NuA1, NmA1, and NwA1 treatments obviously reduced the yield-scaled GHGI by 21.3%, 16.3%, and 12.4%, respectively, relative to the corresponding NuA0, NmA0, and NwA0 treatments. Overall, although three N fertilizers would increase the GWP, combining an ameliorant amendment with N fertilizer can effectively reduce the yield-scaled GHGI and meanwhile increase the grain yield, particularly the NmA1 strategy.

PMID- 29589235 TI - Attenuating effects of caffeic acid phenethyl ester and betaine on abamectin induced hepatotoxicity and nephrotoxicity. AB - Abamectin (ABM) is a widely utilized potent anthelmintic and insecticidal agent. In this study, we investigated the protective effects of caffeic acid phenethyl ester (CAPE) and betaine (BET) against ABM-induced hepatotoxicity and nephrotoxicity in rats. Forty rats were divided into five groups, receiving either oral saline solution (normal control), oral ABM at a dose of 2 mg/kg BW (1/5 LD50), CAPE (10 MUmol/kg BW intraperitoneally) followed by ABM, or BET supplementation at a dose of 250 mg/kg BW followed by ABM administration, while group V rats received a combination of i.p. CAPE and oral BET in the same doses before receiving ABM. Biochemical analysis showed that ABM administration significantly (p < 0.05) increased serum levels of aminotransferases, alkaline phosphatase, lactate dehydrogenase, and cholesterol, as well as serum creatinine and urea. Compared to the control group, ABM-intoxicated rats had significantly (p < 0.05) higher tissue concentrations of nitric oxide and malondialdehyde, as well as lower tissue glutathione concentration, total antioxidant capacity, and antioxidant enzymatic activity (glutathione peroxidase, superoxide dismutase, and catalase). Histopathological examination of hepatic and renal tissues of ABM intoxicated rats showed acute inflammatory and necrotic changes. Pretreatment with CAPE and/or BET reversed the biochemical and histopathological alterations of ABM on the liver and kidneys. Therefore, CAPE and BET (alone or in combination) could be promising protective agents against ABM-induced hepatotoxicity and nephrotoxicity. Future studies should confirm our findings and evaluate the other molecular effects are involved in the combination chemoprotection of CAPE and BET. PMID- 29589237 TI - Khuzestan dust phenomenon: a content analysis of most widely circulated newspapers. AB - Dust is an atmospheric phenomenon that causes adverse environmental effects. It is deemed to have harmful effects on health, economics, and climate. This study aimed to analyze the content published on the phenomenon of dust in the widely circulated newspapers in Iran. We investigated the content of all national and provincial newspapers that were published between July and August 2014. Data on the materials related to the dust phenomenon in the newspapers were categorized and coded. From a total of 510 newspaper issues, 143 articles were devoted to the dust phenomenon which 74.1% of them were published in provincial newspapers. Among the national newspapers, Hamshahri newspaper with 16 headlines and from the provincial newspapers; Karoon with 23 headlines published the highest number of articles on dust phenomenon. 45.5% of content on dust were printed on the first page of the newspapers. The most common approach to the type of content published in these newspapers was an interview. Moreover, we noticed that 28.7% of the content published in the newspapers was related to the health issue. The media plays an important role in the transmission of health information. Weaknesses in addressing the causes of dust occurrence and also in providing solutions for the dust control and prevention were noticeable in the content published in the newspaper. It seems necessary to take practical measures to disseminate relevant information to dust and also address the needs of the target audience community influenced by the dust phenomenon properly.

AB - More than 85% of the rural Indian households use traditional solid biofuels (SBFs) for daily cooking. Burning of the easily available unprocessed solid fuels in inefficient earthen cooking stoves produce large quantities of particulate matters. Smaller particulates, especially with aerodynamic diameter of 2.5 MUm or less (PM2.5), largely generated during cooking, are considered to be health damaging in nature. In the present study, kitchen level exposure of women cooks to fine particulate matters during lunch preparation was assessed considering kitchen openness as surrogate to the ventilation condition. Two-way ANCOVA analysis considering meal quantity as a covariate revealed no significant interaction between the openness and the seasons explaining the variability of the personal exposure to the fine particulate matters in rural kitchen during cooking. Multiple linear regression analysis revealed the openness as the only significant predictor for personal exposure to the fine particulate matters. In the present study, the annual average fine particulate matter exposure concentration was found to be 974 MUg m-3. PMID- 29589239 TI - Phthalate exposure and high blood pressure in adults: a cross-sectional study in China. AB - Widespread phthalate exposure has been recently documented and is hypothesized to increase blood pressure (BP) in humans. However, current studies have provided inconclusive evidence for an association between phthalate exposure and BP. Human epidemiologic studies on the topic remain lacking. Therefore, this study aims to examine the association between serum phthalate concentrations and BP in a Chinese population. We measured several parameters of BP (systolic BP, diastolic BP, total cholesterol, and triglyceride) and the concentrations of 16 phthalates (dimethyl phthalate (DMP), diethyl phthalate, diisobutyl phthalate, dibutyl phthalate (DBP), bis (2-methoxyethyl) phthalate, bis (4-methyl-2-pentyl) phthalate, bis (2-ethoxyethyl) phthalate, diamyl phthalate, dihexyl phthalate, benzyl butyl phthalate, bis (2-nbutoxyethyl) phthalate (DBEP), dicyclohexyl phthalate, bis (2-ethyl hexyl) phthalate (DEHP), diisononyl phthalate, diphenyl phthalate, and di-n-octyl phthalate) in the serum of 474 adults recruited from a primary health care clinic. The relationship between serum phthalate concentrations and BP parameters was assessed with multivariate linear regressions. DBP was the most ubiquitous and dominant contaminant in the study population. The systolic BP of subjects in the median-exposure DEHP group significantly increased by 2.96 mmHg (p < 0.05) relative to that of subjects in the low-exposure group. Significant positive dose-related associations of DMP and DBEP with the levels of total cholesterol in serum (p for trend < 0.05) were also found. These associations persisted even when considering exposure to multiple phthalates. Our results suggested that phthalate exposure might increase BP in adults. However, our findings warrant further studies in a larger and more general population. PMID- 29589241 TI - Redox buffering and de-coupling of arsenic and iron in reducing aquifers across the Red River Delta, Vietnam, and conceptual model of de-coupling processes. AB - Analysis of over 500 groundwater samples from throughout the Red River Delta indicates de-coupling of dissolved arsenic (As) and dissolved iron (Fe). Sorting of all data along the redox potentials suggests re-adsorption of As released initially from Mn(IV)-oxyhydroxides and later from Fe(III)-oxyhydroxides on remaining ferric phases at moderate redox levels. A gradually decreasing specific surface area available for re-adsorption of As probably plays a role as a consequence of limited reactivity of more crystalline phases such as goethite and hematite. At low redox levels, concentrations of Fe and phosphate decrease, but As concentrations keep increasing and most As is present as As(III) with limited adsorption affinity. Based on the results of speciation modeling, the water is supersaturated with respect to siderite and vivianite. A general conceptual model of As and Fe behavior is presented, suggesting that coupled behavior is possible in two geochemical "windows", i.e., 1: between saturation of remaining adsorption sites and the onset of siderite and vivianite precipitation, and 2: after the beginning of secondary sulfide phases precipitation and during methanogenesis. The de-coupling of As from Fe is common and has been observed at many sites around the world where As is released as a consequence of redox processes, e.g., in Bangladesh, West Bengal and Assam in India, the Mekong Delta in Cambodia and Vietnam, and Taiwan. The presented general conceptual model of de-coupling processes can be applied to the interpretation of As and Fe data, and, thus, it can help in the preparation of a site conceptual model which is a necessary prerequisite for reactive transport modeling.

AB - Metal oxide nanoparticles are widely used in industries, and peak level can be confirmed in their surroundings. In the present study, the sub-lethal effects of CuO-NPs from low to high concentration as 0.5 to 1.5 mg/L were observed in tilapia (Oreochromis mossambicus). Accumulation of copper from CuO-NPs was increased with the increase in doses, and maximum accumulation was found in the gill than liver and muscles. The increased lipid peroxidation level was observed in the gill as compared to liver, and the similar results were obtained in catalase and glutathione while superoxide dismutase level was higher in the liver than gills. In histological alterations, gill edema, curved tips, fusion of gill lamellae, and thickening of primary and secondary gill lamellae were observed. Necrosis and apoptosis with condensed nuclear bodies and pyknotic nuclei were observed in the liver at the highest dose concentration. In a genotoxic study, the highest value of % tail DNA and olive tail movement was observed with increasing concentrations. Copper oxide nanoparticles has greater potential to accumulate in the soft tissues, which may cause respiratory distress such as oxidative stress, induction of antioxidant defense by raising glutathione, organ pathology, and genotoxicity. PMID- 29589242 TI - Evaluation of iron loading in four types of hepatopancreatic cells of the mangrove crab Ucides cordatus using ferrocene derivatives and iron supplements. AB - The mangrove crab Ucides cordatus is a bioindicator of aquatic contamination. In this work, the iron availability and redox activity of saccharide-coated mineral iron supplements (for both human and veterinary use) and ferrocene derivatives in Saline Ucides Buffer (SUB) medium were assessed. The transport of these metallodrugs by four different hepatopancreatic cell types (embryonic (E), resorptive (R), fibrillar (F), and blister (B)) of U. cordatus were measured. Organic coated iron minerals (iron supplements) were stable against strong chelators (calcein and transferrin). Ascorbic acid efficiently mediated the release of iron only from ferrocene compounds, leading to redox-active species. Ferrous iron and iron supplements were efficient in loading iron to all hepatopancreatic cell types. In contrast, ferrocene derivatives were loaded only in F and B cell types. Acute exposition to the iron compounds resulted in cell viability of 70-95%, and to intracellular iron levels as high as 0.40 MUmol L-1 depending upon the compound and the cell line. The easiness that iron from iron metallodrugs was loaded/transported into U. cordatus hepatopancreatic cells reinforces a cautionary approach to the widespread disposal and use of highly bioavailable iron species as far as the long-term environmental welfare is concerned. PMID- 29589243 TI - Characterization and phenanthrene sorption of organic matter fractions isolated from organic and mineral soils. AB - Sorption of phenanthrene (PHE) to humic acid (HA) and humin (HM) fractions isolated from organic and mineral soils was investigated to better understand sorption processes in varying soil types. Samples were characterized by elemental analysis, X-ray photoelectron spectroscopy, 13C nuclear magnetic resonance, and CO2 adsorption. No clear correlation was found between the distribution coefficient (Kd) and the bulk polarity of the soil organic matters (SOMs). By contrast, PHE Kd values generally increased with increasing surface polarity of the tested SOMs, implying that surface polarity may play a more important role in PHE sorption than the bulk one. The organic carbon (OC)-normalized Kd values (Koc) of HMs were higher than those of HAs as a result of the higher aliphatic C contents of HMs. For SOMs isolated from mineral soil (MI-SOMs), part of the aliphatic domains may be tightly associated with minerals and were not accessible to PHE molecules, resulting in lower PHE Koc values of MI-SOMs than the corresponding fractions extracted from the organic soil. This study implies that both chemical characteristics and physical conformation of SOMs are paramount considerations when investigating sorption process of hydrophobic organic compounds in soils. PMID- 29589244 TI - Performance and mechanisms of thermally treated bentonite for enhanced phosphate removal from wastewater. AB - Optimization of clays as adsorbent for low concentration phosphorus removal from wastewater has received increasing attention in recent years. This study explored the feasibility of using bentonite as an adsorbent for phosphate (P) removal from synthetic wastewater, by assessing the performance of thermally treated bentonite for P removal and elucidating the mechanisms of P adsorption. Natural bentonite (B25) was thermally treated at 100-1000 degrees C (B100-B1000) for 2 h. Physical and chemical properties were measured by the SEM, XRD, pore size distribution, EDX, and cation exchange capacity (CEC) methods. Thermal treatment increased P sorption capacity of bentonite and that B800 had a higher P sorption capacity (6.94 mg/g) than B25 (0.237 mg/g) and B400 (0.483 mg/g) using the Langmuir isotherm equation. Study of sorption kinetics indicated that B800 rapidly removed 94% of P from a 10 mg P/L solution and the pseudo-second-order equation fitted the data well. The Ca2+ release capacity of B800 (1.31 mg/g) was significantly higher than that of B25 (0.29 mg/g) and B400 (0.40 mg/g) (p < 0.05). The initial pH level had a smaller impact on P removal efficiency for B800 than that of B25 and B400. Ca-P was the main fraction of P adsorbed onto B800, and Ca10-P was the main species (41.4%). The main factors affecting the phosphorous adsorption capacity of B800 were changed crystal structure, strong calcium release capacity, and improved stability in different pH solutions. The results demonstrated that thermally treated bentonite (B800) has the potential to be an efficient adsorbent for removal of low-concentration phosphorus from wastewater. PMID- 29589246 TI - Treatment of municipal sludge by Fenton oxidation combined vacuum preloading. AB - Municipal sludge, composed of numerous types of organic matter with a gel structure, has high water content, low permeability coefficient, and poor mechanical properties. Fenton oxidation-assisted vacuum preloading method for municipal sludge treatment was proposed. First, the municipal sludge was oxidized and treated with Fenton's reagent; then, drainage consolidation was performed on the sludge with the vacuum preloading method. The optimal dosage of Fenton's reagent for municipal sludge was determined. Comparative experiments of the one dimensional consolidation of municipal sludge treated with Fenton's reagent and the drainage consolidation by Fenton oxidation-assisted vacuum preloading were conducted. The results reveal that the specific resistance of municipal sludge decreases upon Fenton oxidation by approximately 98.6% at the optimal dosage of 22%, sludge water content decreases from 82.14 to 66.67%, volume reduces by ~ 40%, and unconfined compressive strength increases to 55 kPa. PMID- 29589245 TI - Life cycle of PCBs and contamination of the environment and of food products from animal origin. AB - This report gives a summary of the historic use, former management and current release of polychlorinated biphenyls (PCBs) in Germany and assesses the impact of the life cycle of PCBs on the contamination of the environment and of food products of animal origin. In Germany 60,000 t of PCBs were used in transformers, capacitors or as hydraulic oils. The use of PCB oils in these "closed applications", has been banned in Germany in 2000. Thirty to 50% of these PCBs were not appropriately managed. In West Germany, 24,000 t of PCBs were used in open applications, mainly as additive (plasticiser, flame retardant) in sealants and paints in buildings and other construction. The continued use in open applications has not been banned, and in 2013, an estimated more than 12,000 t of PCBs were still present in buildings and other constructions. These open PCB applications continuously emit PCBs into the environment with an estimated release of 7-12 t per year. This amount is in agreement with deposition measurements (estimated to 18 t) and emission estimates for Switzerland. The atmospheric PCB releases still have an relevant impact on vegetation and livestock feed. In addition, PCBs in open applications on farms are still a sources of contamination for farmed animals. Furthermore, the historic production, use, recycling and disposal of PCBs have contaminated soils along the lifecycle. This legacy of contaminated soils and contaminated feed, individually or collectively, can lead to exceedance of maximum levels in food products from animals. In beef and chicken, soil levels of 5 ng PCB-TEQ/kg and for chicken with high soil exposure even 2 ng PCB-TEQ/kg can lead to exceedance of EU limits in meat and eggs. Areas at and around industries having produced or used or managed PCBs, or facilities and areas where PCBs were disposed need to be assessed in respect to potential contamination of food-producing animals. For a large share of impacted land, management measures applicable on farm level might be sufficient to continue with food production. Open PCB applications need to be inventoried and better managed. Other persistent and toxic chemicals used as alternatives to PCBs, e.g. short chain chlorinated paraffins (SCCPs), should be assessed in the life cycle for exposure of food-producing animals and humans. PMID- 29589247 TI - Element uptake and physiological responses of Lactuca sativa upon co-exposures to tourmaline and dissolved humic acids. AB - Element migration and physiological response in Lactuca sativa upon co-exposure to tourmaline (T) and dissolved humic acids (DHAs) were investigated. Different fractions of DHA1 and DHA4 and three different doses of T were introduced into Hoagland's solution. The results indicated that T enhanced the contents of elements such as N and C, Si and Al in the roots and shoots. The correlation between TF values of Si and Al (R2 = 0.7387) was higher than that of Si and Mn (R2 = 0.4961) without the presence of DHAs. However, both DHA1 and DHA4 increased the correlation between Si and Mn, but decreased the one between Si and Al. CAT activities in T treatments were positively correlated to the contents of N and Al in the shoots, whose R 2 was 0.9994 and 0.9897, respectively. In the co-exposure of DHAs and tourmaline, DHA4 exhibited more impacts on element uptake, CAT activities, as well as ABA contents in comparison with the presence of DHA1, regardless of the T exposure doses. These results suggested that DHAs have effects on mineral element behaviors and physiological response in Lactuca sativa upon exposure to tourmaline for the first time, which had great use in guiding soil remediation. PMID- 29589248 TI - Characterization of CDOM absorption of reservoirs with its linkage of regions and ages across China. AB - The absorption of chromophoric dissolved organic matter (CDOM) is an important part of light absorptions in aquatic systems. The increasing eutrophication of reservoirs and regional characteristics would affect the CDOM properties sensitively which would be important for the application of remote sensing monitoring. The highest (4.07 +/- 2.31 m-1) and lowest (0.79 +/- 0.67 m-1) CDOM concentrations of reservoirs were observed in the northeastern lake region (NER) and Tibetan Plateau lake region (TPR), respectively. The differences between S275 295 among the five lake regions were significant (p < 0.05) in which the steepest S275-295 (0.0173 +/- 0.0026 nm-1) was observed in TPR and the shallowest (0.0326 +/- 0.0152 nm-1) in Yungui Plateau lake region (YGR). The strong relationships between aCDOM(355) and DOC appeared in the NER (R2 = 0.43), eastern lake region (EAR) (R2 = 0.69), Mengxin lake region (MXR) (R2 = 0.61), and YGR (R2 = 0.79) which would be a good proxy for DOC in regional reservoirs. Most of all, the correlation between reservoir's establishing time and CDOM absorption under oligotrophic states was relatively strong in the EAR and MXR regions. It indicated that the establishing time of reservoirs affected the CDOM absorption to some extent under the oligotrophic states without much human disturbance. Our results indicate CDOM absorption varies with regions, and the relationships between CDOM and DOC are variable for different regions. Therefore, DOC estimation in reservoirs through CDOM absorption needs to be considered according to lake regions and trophic states. PMID- 29589249 TI - Rural-urban disparities in the utilization of mental health inpatient services in China: the role of health insurance. AB - Reducing rural-urban disparities in health and health care has been a key policy goal for the Chinese government. With mental health becoming an increasingly significant public health issue in China, empirical evidence of disparities in the use of mental health services can guide steps to reduce them. We conducted this study to inform China's on-going health-care reform through examining how health insurance might reduce rural-urban disparities in the utilization of mental health inpatient services in China. This retrospective study used 10 years (2005-2014) of hospital electronic health records from the Shandong Center for Mental Health and the DaiZhuang Psychiatric Hospital, two major psychiatric hospitals in Shandong Province. Health insurance was measured using types of health insurance and the actual reimbursement ratio (RR). Utilization of mental health inpatient services was measured by hospitalization cost, length of stay (LOS), and frequency of hospitalization. We examined rural-urban disparities in the use of mental health services, as well as the role of health insurance in reducing such disparities. Hospitalization costs, LOS, and frequency of hospitalization were all found to be lower among rural than among urban inpatients. Having health insurance and benefiting from a relatively high RR were found to be significantly associated with a greater utilization of inpatient services, among both urban and rural residents. In addition, an increase in the RR was found to be significantly associated with an increase in the use of mental health services among rural patients. Consistent with the existing literature, our study suggests that increasing insurance schemes' reimbursement levels could lead to substantial increases in the use of mental health inpatient services among rural patients, and a reduction in rural-urban disparities in service utilization. In order to promote mental health care and reduce rural-urban disparities in its utilization in China, improving rural health insurance coverage (e.g., reducing the coinsurance rate) would be a powerful policy instrument.

AB - The work describes systematic development of nanomicellar cationic supersaturable self-nanoemulsifying drug delivery systems (CS-SNEDDS) for augmenting oral biopharmaceutical performance of raloxifene hydrochloride. Plain SNEDDS formulation containing Capryol 90, Cremophor RH 40, and Transcutol HP was optimized using D-optimal mixture design. SNEDDS were characterized for emulsification time, globule size, in vitro drug release, and ex vivo permeation. The CS-SNEDDS formulation was prepared from the optimized SNEDDS by adding oleylamine as the cationic charge inducer and HPMC as the polymeric precipitation inhibitor. Evaluation of CS-SNEDDS was carried out through in vitro cell line studies on Caco-2 and MCF-7 cells, in situ perfusion, and in vivo pharmacokinetic studies, which indicated significant improvement in biopharmaceutical attributes of the drug from CS-SNEDDS over plain drug. PMID- 29589251 TI - Hepatocellular adenoma in a woman who was undergoing testosterone treatment for gender identity disorder. AB - A 32-year-old Japanese woman was admitted to our hospital for the diagnosis and treatment of multiple liver tumors. She had been receiving 125 mg testosterone enanthate every 2 weeks following female-to-male gender identity disorder (GID) diagnosis at 20 years of age. Ultrasonography, computed tomography, and magnetic resonance imaging showed 11 hepatic nodular tumors with a maximum diameter of 28 mm. Liver tumors with hepatocellular adenoma (HCA) were diagnosed with needle biopsy. Segmentectomy of the left lateral lobe including two lesions, subsegmentectomy of S6 including two lesions, enucleation of each tumor in S5 and S7, and open surgical radiofrequency ablation for each tumor in S4 and S7 were performed. Immunohistochemical specimens showed that the tumor cells were diffusely and strongly positive for glutamine synthetase and that the nuclei were ectopically positive for beta-catenin. Thus, the tumors were diagnosed as beta catenin-activated HCA (b-HCA). Transcatheter arterial chemoembolization plus subsequent radiofrequency ablation was performed for the 3 residual lesions in S4 and S8. Although testosterone enanthate was being continued for GID, no recurrence was observed until at least 22 months after the intensive treatments. HCA development in such patients receiving testosterone should be closely monitored using image inspection. PMID- 29589252 TI - The role of phase shifts of sensory inputs in walking revealed by means of phase reduction. AB - Detailed neural network models of animal locomotion are important means to understand the underlying mechanisms that control the coordinated movement of individual limbs. Daun-Gruhn and Toth, Journal of Computational Neuroscience 31(2), 43-60 (2011) constructed an inter-segmental network model of stick insect locomotion consisting of three interconnected central pattern generators (CPGs) that are associated with the protraction-retraction movements of the front, middle and hind leg. This model could reproduce the basic locomotion coordination patterns, such as tri- and tetrapod, and the transitions between them. However, the analysis of such a system is a formidable task because of its large number of variables and parameters. In this study, we employed phase reduction and averaging theory to this large network model in order to reduce it to a system of coupled phase oscillators. This enabled us to analyze the complex behavior of the system in a reduced parameter space. In this paper, we show that the reduced model reproduces the results of the original model. By analyzing the interaction of just two coupled phase oscillators, we found that the neighboring CPGs could operate within distinct regimes, depending on the phase shift between the sensory inputs from the extremities and the phases of the individual CPGs. We demonstrate that this dependence is essential to produce different coordination patterns and the transition between them. Additionally, applying averaging theory to the system of all three phase oscillators, we calculate the stable fixed points - they correspond to stable tripod or tetrapod coordination patterns and identify two ways of transition between them.

AB - BACKGROUND: Needle breakage during the administration of dental analgesia is an extremely rare event. CASE REPORT: A case of needle breakage during the administration of an inferior alveolar nerve block occurred in a child with KBG syndrome. During the injection, a sudden movement of the child caused the breakage of the needle. The next day, the retrieval of the needle was performed surgically under general analgesia. FOLLOW-UP: Three months after the surgery the healing was good. Two years later the child underwent a dental extraction with the aid of nitrous oxide/oxygen analgesia/anxiolysis. CONCLUSION: Needle fracture is a possible event during the administration of dental analgesia in children. PMID- 29589255 TI - Phylogenetic Flexibility via Hall-Type Inequalities and Submodularity. AB - Given a collection [Formula: see text] of subsets of a finite set X, we say that [Formula: see text] is phylogenetically flexible if, for any collection R of rooted phylogenetic trees whose leaf sets comprise the collection [Formula: see text], R is compatible (i.e. there is a rooted phylogenetic X-tree that displays each tree in R). We show that [Formula: see text] is phylogenetically flexible if and only if it satisfies a Hall-type inequality condition of being 'slim'. Using submodularity arguments, we show that there is a polynomial-time algorithm for determining whether or not [Formula: see text] is slim. This 'slim' condition reduces to a simpler inequality in the case where all of the sets in [Formula: see text] have size 3, a property we call 'thin'. Thin sets were recently shown to be equivalent to the existence of an (unrooted) tree for which the median function provides an injective mapping to its vertex set; we show here that the unrooted tree in this representation can always be chosen to be a caterpillar tree. We also characterise when a collection [Formula: see text] of subsets of size 2 is thin (in terms of the flexibility of total orders rather than phylogenies) and show that this holds if and only if an associated bipartite graph is a forest. The significance of our results for phylogenetics is in providing precise and efficiently verifiable conditions under which supertree methods that require consistent inputs of trees can be applied to any input trees on given subsets of species.

AB - Juniperonic acid (JPA; Delta5,11,14,17-20:4), originally identified in certain gymnosperm seeds, is a rare n-3 polyunsaturated fatty acid (PUFA) with lipid modulating effects on rats and anti-proliferative effects on fibroblast cell proliferation. However, little is known how JPA exerted its immunosuppressive effect. The objective of this study was to investigate whether JPA inhibited the production of inflammatory mediators through the modulation of cellular phospholipid fatty acid compositions. Using standard lipid chemistry techniques in conjunction with argentated column chromatography, high-purity JPA (> 98%) was extracted, isolated, and purified from Biota kernels. When murine RAW264.7 macrophages were incubated with increasing concentrations of JPA, amounts of cellular phospholipid total PUFA, JPA, and Delta7-docosatetraenoic acid (Delta7 DTA; elongation product of JPA) increased in a dose-dependent manner; however, the proportions of total monounsaturated fatty acid (MUFA) and arachidonic acid (AA) decreased. JPA suppressed the production of nitric oxide (NO), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) and the expression of inducible nitric oxide synthase (iNOS) up to 21, 75, 30, and 44%, respectively. The induction of cyclooxygenase-2 (COX-2) over-expression by JPA could account for the doubling of the PGE2 level. Furthermore, JPA suppressed the expression of phosphorylated mitogen-activated protein kinases (MAPK). In a separate study using the mouse ear edema model, we demonstrated that JPA also significantly suppressed inflammation, as measured by ear thickness and biopsy weight. The anti inflammatory properties of JPA could be due, in part, to the incorporation of JPA into cellular phospholipids with subsequent modulation of membrane-mediated MAPK signaling.

AB - BACKGROUND: Neisseria gonorrhoeae is one of the main etiological agents of sexually transmitted diseases. The asymptomatic course of the infection and its resistance to antibiotics can lead to pelvic inflammatory disease and infertility. OBJECTIVES: We developed a polymerase chain reaction (PCR) test using the methyltetrahydrofolate homocysteine methyltransferase reductase (mtrR) gene to identify N. gonorrhoeae and detect reduced susceptibility to antibiotics. MATERIAL AND METHODS: We analysed 250 samples of endocervical exudate from infertile women with a negative diagnosis of N. gonorrhoeae. We designed NGmtr primers to detect N. gonorrhoeae and identify the antibiotic-resistant strain. RESULTS: Of the 250 samples, 60 (24%) tested positive for N. gonorrhoeae using real-time PCR. Our study was validated using the HO primers and the Seeplex STD6 ACE System, with a 100% correlation. Furthermore, the NGmtr primers are specific for N. gonorrhoeae and not for other species. Additionally, the curves generated by real-time PCR differed between wild and variant strains (10.93%). The dissociation temperatures for the wild and variant strains were 86.5 and 89 degrees C, respectively. CONCLUSIONS: The NGmtr primers enabled us to identify N. gonorrhoeae strains with or without reduction of susceptibility to antibiotics. Therefore, this work constitutes a tool that will facilitate the diagnosis of this infection for a low cost and improve patient quality of life. PMID- 29589257 TI - To protect or not to protect: examining reasons for sun protection among young women at risk for skin cancer. AB - We aimed to further the understanding of the low rates of sun protection in young women at risk for skin cancer. Six-hundred-sixty-one daily diary entries were received via text message over 14 days from 56 young women at moderate to high risk of developing skin cancer. Women reported whether or not they used sun protection and also listed what their reasons were for using protection or not using sun protection each day. Multi-level modeling was used to examine the influence of study variables when predicting daily sun protection or lack of protection. The number of days in which sun protection was reported was positively associated with "habit" and "prevention" as reasons for protection and negatively associated with "not-needed" and "unprepared" as reasons for non protection. Self-reported sun protection increased over the 14-day study period. Results of this study suggest the potential value of interventions aimed at motives for sun-protection behaviors. PMID- 29589258 TI - Toward a real-time system for temporal enhanced ultrasound-guided prostate biopsy. AB - PURPOSE: We have previously proposed temporal enhanced ultrasound (TeUS) as a new paradigm for tissue characterization. TeUS is based on analyzing a sequence of ultrasound data with deep learning and has been demonstrated to be successful for detection of cancer in ultrasound-guided prostate biopsy. Our aim is to enable the dissemination of this technology to the community for large-scale clinical validation. METHODS: In this paper, we present a unified software framework demonstrating near-real-time analysis of ultrasound data stream using a deep learning solution. The system integrates ultrasound imaging hardware, visualization and a deep learning back-end to build an accessible, flexible and robust platform. A client-server approach is used in order to run computationally expensive algorithms in parallel. We demonstrate the efficacy of the framework using two applications as case studies. First, we show that prostate cancer detection using near-real-time analysis of RF and B-mode TeUS data and deep learning is feasible. Second, we present real-time segmentation of ultrasound prostate data using an integrated deep learning solution. RESULTS: The system is evaluated for cancer detection accuracy on ultrasound data obtained from a large clinical study with 255 biopsy cores from 157 subjects. It is further assessed with an independent dataset with 21 biopsy targets from six subjects. In the first study, we achieve area under the curve, sensitivity, specificity and accuracy of 0.94, 0.77, 0.94 and 0.92, respectively, for the detection of prostate cancer. In the second study, we achieve an AUC of 0.85. CONCLUSION: Our results suggest that TeUS-guided biopsy can be potentially effective for the detection of prostate cancer. PMID- 29589259 TI - Prostate segmentation in transrectal ultrasound using magnetic resonance imaging priors. AB - PURPOSE: In the current standard of care, real-time transrectal ultrasound (TRUS) is commonly used for prostate brachytherapy guidance. As TRUS provides limited soft tissue contrast, segmenting the prostate gland in TRUS images is often challenging and subject to inter-observer and intra-observer variability, especially at the base and apex where the gland boundary is hard to define. Magnetic resonance imaging (MRI) has higher soft tissue contrast allowing the prostate to be contoured easily. In this paper, we aim to show that prostate segmentation in TRUS images informed by MRI priors can improve on prostate segmentation that relies only on TRUS images. METHODS: First, we compare the TRUS based prostate segmentation used in the treatment of 598 patients with a high quality MRI prostate atlas and observe inconsistencies at the apex and base. Second, motivated by this finding, we propose an alternative TRUS segmentation technique that is fully automatic and uses MRI priors. The algorithm uses a convolutional neural network to segment the prostate in TRUS images at mid-gland, where the gland boundary can be clearly seen. It then reconstructs the gland boundary at the apex and base with the aid of a statistical shape model built from an MRI atlas of 78 patients. RESULTS: Compared to the clinical TRUS segmentation, our method achieves similar mid-gland segmentation results in the 598-patient database. For the seven patients who had both TRUS and MRI, our method achieved more accurate segmentation of the base and apex with the MRI segmentation used as ground truth. CONCLUSION: Our results suggest that utilizing MRI priors in TRUS prostate segmentation could potentially improve the performance at base and apex. PMID- 29589260 TI - Real-time inextensible surgical thread simulation. AB - PURPOSE: This paper discusses a real-time simulation method of inextensible surgical thread based on the Cosserat rod theory using position-based dynamics (PBD). The method realizes stable twining and knotting of surgical thread while including inextensibility, bending, twisting and coupling effects. METHODS: The Cosserat rod theory is used to model the nonlinear elastic behavior of surgical thread. The surgical thread model is solved with PBD to achieve a real-time, extremely stable simulation. Due to the one-dimensional linear structure of surgical thread, the direct solution of the distance constraint based on tridiagonal matrix algorithm is used to enhance stretching resistance in every constraint projection iteration. In addition, continuous collision detection and collision response guarantee a large time step and high performance. Furthermore, friction is integrated into the constraint projection process to stabilize the twining of multiple threads and complex contact situations. RESULTS: Through comparisons with existing methods, the surgical thread maintains constant length under large deformation after applying the direct distance constraint in our method. The twining and knotting of multiple threads correspond to stable solutions to contact and friction forces. A surgical suture scene is also modeled to demonstrate the practicality and simplicity of our method. CONCLUSIONS: Our method achieves stable and fast simulation of inextensible surgical thread. Benefiting from the unified particle framework, the rigid body, elastic rod, and soft body can be simultaneously simulated. The method is appropriate for applications in virtual surgery that require multiple dynamic bodies. PMID- 29589261 TI - Skeletal muscle overexpression of short isoform Sirt3 altered mitochondrial cardiolipin content and fatty acid composition. AB - Cardiolipin (CL) is a phospholipid at the heart of mitochondrial metabolism, which plays a key role in mitochondrial function and bioenergetics. Among mitochondrial activity regulators, SIRT3 plays a crucial role in controlling the acetylation status of many enzymes participating in the energy metabolism in particular concerning lipid metabolism and fatty acid oxidation. Data suggest that possible connection may exist between SIRT3 and CL status that has not been evaluated in skeletal muscle. In the present study, we have characterized skeletal muscle lipids as well as mitochondrial lipids composition in mice overexpressing long (SIRT3-M1) and short (SIRT3-M3) isoforms of SIRT3. Particular attention has been paid for CL. We reported no alteration in muscle lipids content and fatty acids composition between the two mice SIRT3 strains and the control mice. However, mitochondrial CL content was significantly decreased in SIRT3-M3 mice and associated to an upregulation of tafazzin gene expression. In addition, mitochondrial phospholipids and fatty acids composition was altered with an increase in the PC/PE ratio and arachidonic acid content and a reduction in the MUFA/SFA ratio. These modifications in mitochondrial membrane composition are associated with a reduction in the enzymatic activities of mitochondrial respiratory chain complexes I and IV. In spite of these mitochondrial enzymatic alterations, skeletal muscle mitochondrial respiration remained similar in SIRT3 M3 and control mice. Surprisingly, none of those metabolic alterations were detected in mitochondria from SIRT3-M1 mice. In conclusion, our data indicate a specific action of the shorter SIRT3 isoform on lipid mitochondrial membrane biosynthesis and functioning. PMID- 29589262 TI - Ocimum basilicum but not Ocimum gratissimum present cytotoxic effects on human breast cancer cell line MCF-7, inducing apoptosis and triggering mTOR/Akt/p70S6K pathway. AB - Breast cancer is the major cause of death by cancer in women worldwide and in spite of the many drugs for its treatment, there is still the need for novel therapies for its control. Ocimum species have been used by traditional medicine to control several diseases, including cancer. We have previously characterized the antidiabetic properties of the unfractionated aqueous leaf extracts of Ocimum basilicum (OB) and Ocimum gratissimum (OG), modulating glucose metabolism in diabetic mice. Since glucose metabolism is primordial for cancer cells survival, we hypothesized that these extracts are effective against cancer cells. The unfractionated aqueous leaf extracts of OB and OG were chemically characterized and tested for their cytotoxic, cytostatic and anti-proliferative properties against the human breast cancer cell line MCF-7. Both extracts presented cytostatic effects with an 80% decrease in MCF-7 cell growth at 1 mg/mL. However, only OB promoted cytotoxic effects, interfering with the cell viability even after interruption of the treatment. Moreover, OB but not OG affected the cell proliferation and metabolism, evaluated in terms of lactate production and intracellular ATP content. After 24 h of treatment, OB treated cells presented an apoptotic profile, while OG treated cells were more necrotic. The treatment with both extracts also activated AMPK, but OB was much more efficient than OG in promoting this. The activation of mTOR signaling, another survival pathway was promoted by OB, whereas OG failed to activate it. In the end, we conclude that OB extract is efficient against the human breast cancer cell line. PMID- 29589263 TI - Combination of temperature shift and hydrolysate addition regulates anti-IgE monoclonal antibody charge heterogeneity in Chinese hamster ovary cell fed-batch culture. AB - Charge heterogeneity has been broadly studied as a critical quality attribute during monoclonal antibody (mAb) production that may subsequently affect product stability and biopotency. However, the charge variation distribution is poorly controlled, so methods of more effective control need to be explored. In this study, the combined effects of temperature shift (37-34, 37-32, or 37-30 degrees C) and hydrolysate addition (0.100 g/L) to culture feed on the charge heterogeneity of anti-IgE mAb were investigated. The results showed that the distribution of charge variation was significantly regulated by the combination of hydrolysate addition with a highly sub-physiological temperature (34 degrees C). In addition, under this condition, the main peak content significantly increased, and the acidic peak content significantly decreased. Furthermore, we explored Lys variant content, which is the major basic variant content, as well as its relationship with temperature shift and hydrolysate addition. Lys variant levels were positively related to the Lys and Arg concentrations in the medium and negatively related to carboxypeptidase B and carboxypeptidase H transcript levels. The combination of temperature shift and hydrolysate addition can thus effectively improve anti-IgE mAb charge heterogeneity and significantly increase main variant levels and decrease acidic variant levels.

PMID- 29589266 TI - Efficient Culture of Intestinal Organoids with Blebbistatin. AB - The intestinal epithelium is one of the most rapidly self-renewing tissues throughout life in mammals. A small population of stem cells at the base of crypt in the epithelium can continually self-renew and give rise to differentiated epithelial cells. The self-renewal and differentiation of intestinal stem cells are under a tight control during homeostasis, and disruption of this balancing regulation leads to intestinal degeneration or tumorigenesis. Accordingly, exploration of the mechanism underlying the regulation of stem cells is essential for the understanding and treatment of intestinal disorders. As traditional methods using mice models are costly and time-consuming, the recently established ex vivo intestinal organoids model provides an ideal tool to investigate the mechanisms regulating the self-renewal and differentiation of intestinal stem cells. The intestinal organoids recapitulate major characteristics in both structure and function of intestinal epithelium in vivo. Here, we describe a new protocol to generate the intestinal organoids from both crypts and single stem cells with a higher efficiency using the small molecule blebbistatin and provide an approach to assess the self-renewal and differentiation of stem cells in intestinal organoids. PMID- 29589264 TI - Short- and Long-Term Oncological Outcome After Rectal Cancer Surgery: a Systematic Review and Meta-Analysis Comparing Open Versus Laparoscopic Rectal Cancer Surgery. AB - BACKGROUND: While several trials have compared laparoscopic to open surgery for colon cancer showing similar oncological results, oncological quality of laparoscopic versus open rectal resection is not well investigated. METHODS: A systematic literature search for randomized controlled trials was conducted in MEDLINE, the Cochrane Library, and Embase. Qualitative and quantitative meta analyses of short-term (rate of complete resections, number of harvested lymph nodes, circumferential resection margin positivity) and long-term (recurrence, disease-free and overall survival) oncologic results were conducted. RESULTS: Fourteen randomized controlled trials were identified including 3528 patients. Patients in the open resection group had significantly more complete resections (OR 0.70; 95% CI 0.51-0.97; p = 0.03) and a higher number of resected lymph nodes (mean difference - 0.92; 95% CI - 1.08 to 0.75; p < 0.001). No differences were detected in the frequency of positive circumferential resection margins (OR 0.82; 95% CI 0.62-1.10; p = 0.18). Furthermore, no significant differences of long-term oncologic outcome parameters after 5 years including locoregional recurrence (OR 0.95; 95% CI 0.44-2.05; p = 0.89), disease-free survival (OR 1.16; 95% CI 0.84 1.58; p = 0.36), and overall survival (OR 1.04; 95% CI 0.76-1.41; p = 0.82) were found. Most trials exhibited a relevant risk of bias and several studies provided no information on the surgical expertise of the participating surgeons. CONCLUSION: Differences in oncologic outcome between laparoscopic and open rectal surgery for rectal cancer were detected for the complete resection rate and the number of resected lymph nodes in favor of the open approach. No statistically significant differences were found in oncologic long-term outcome parameters. PMID- 29589267 TI - Effect of Aluminum Exposure on Glucose Metabolism and Its Mechanism in Rats. AB - The effects of aluminum (Al) exposure on glucose metabolism and its mechanism were investigated. A total of 30 healthy Wistar male rats were randomly divided into two groups: control (GC) and experimental (GE). The GC group received intraperitoneal normal saline. The GE was established by intraperitoneal injected AlCl3 solution at 10 mg/kg for 30 days. Fasting blood glucose (FBG) and serum levels of insulin (FINS) were measured. The insulin resistance index (HOMA-IR) and pancreatic beta cell function index (HOMA-beta) were calculated and analyzed with homeostasis model assessment (HOMA). Pancreatic tissue was taken for pathological examination. Glucose transporter 4 (GLUT4) expression in skeletal muscle was detected by quantitative PCR and Western blot. Levels of FBG and HOMA IR in GE were higher than those in GC at day 10 and 20 (P < 0.05). FINS in GE were higher than those in GC at day 10 and 20, and lower than those in GC at day 30 (P < 0.05). HOMA-beta in GE was lower than that of GC at every time point (P < 0.05). Pathology showed that pancreatic damage changed more profoundly with prolongation of time in GE. Expression levels of GLUT4 mRNA and protein in rat skeletal muscle in GE were significantly lower than those in GC (P < 0.05). The results suggested that Al exposure affected glucose metabolism through pancreatic damage and reduction of GLUT4 expression. PMID- 29589268 TI - Changes in Trace Elements During Early Stages of Chronic Kidney Disease in Type 2 Diabetic Patients. AB - Trace elements can influence glucose metabolism and be related to oxidative stress in type 2 diabetes mellitus. Moreover, trace elements play important roles in the nephrotic complications of these patients. Nevertheless, few investigations have been made into the changes in the levels of trace elements in diabetic patients at various stages of chronic kidney disease (CKD). The aims of this present study were to determine the levels of some important trace elements in diabetic patients during the early stages of CKD and to identify the relationship between these elements and CKD progression in type 2 diabetic patients. One hundred and forty-eight type 2 diabetic patients with chronic kidney diseases were recruited into this study. The subjects were grouped into four stages (1, 2, 3a, 3b) of CKD, according to their urine protein levels and estimated glomerular filtration rates (eGFRs). The levels of serum zinc and iron exhibited a statistically significant decreasing trend (P trend = 0.032 and 0.047, respectively) from stage 1 to stage 3b after adjustment for age, gender, smoking, alcohol consumption, education, hypertension, and body mass index. The other tested elements, including copper, magnesium, selenium, chromium, and manganese, did not display any significant trends upon proceeding from stage 1 to stage 3b. Thus, serum zinc and iron appear to be useful markers when evaluating the early progression of CKD in type 2 diabetic patients. PMID- 29589269 TI - Reduced Myocardial Mitochondrial ROS Production in Mechanically Unloaded Hearts. AB - Mechanical ventricular unloading in advanced heart failure (HF) has been shown to induce reverse remodeling in myocardial tissues. Little is known about the impact of ventricular unloading on myocardial energy metabolism. We hypothesized that left ventricular unloading reduces myocardial mitochondrial reactive oxygen species (ROS) production and improves mitochondrial coupling efficiency in patients suffering from advanced HF. Left ventricular tissue specimens were harvested from explanted hearts at the time of transplantation. We compared myocardial metabolism in explanted hearts supported with an unloading ventricular assist device prior to transplantation (LVAD-HTX; n = 9) with tissue specimens of unsupported failing hearts (HTX; n = 6). Myocardial mitochondrial ROS production was decreased by 40% in LVAD-HTX compared to HTX patients (1.5 +/- 0.3 vs. 0.9 +/ 0.1 pmol/(s/mg); p < 0.05). High-resolution respirometry revealed increased mitochondrial coupling efficiency in LVAD-HTX patients (respiratory/control ratio 1.7 +/- 0.2 vs. 1.2 +/- 0.2; p < 0.05). In conclusion, ventricular unloading is related to decreased mitochondrial ROS production and increased coupling efficiency in myocardium of human failing hearts, suggesting a novel pathomechanism of unloading-associated cardioprotection. PMID- 29589271 TI - Towards a Treatment for Intolerance of Uncertainty for Autistic Adults: A Single Case Experimental Design Study. AB - Intolerance of uncertainty (IU) is indicated as an important transdiagnostic process variable in a range of anxiety disorders. Anxiety is very common in autistic adults. This study evaluates a manualised treatment programme for autistic adults, which focused on IU. An eight session programme (CUES-A(c)) was developed and delivered to four autistic adults on an individual basis. A single case experimental design was used to provide a preliminary evaluation of the feasibility, acceptability and preliminary effectiveness of the programme. Data regarding retention, acceptability and feasibility indicate that the participants valued the programme. Analyses of outcome measures indicate that the programme has promise as a treatment option for autistic adults experiencing IU. PMID- 29589272 TI - Embedding Autism Spectrum Disorder Diagnosis Within the Medical Home: Decreasing Wait Times Through Streamlined Assessment. AB - Long waits for diagnostic assessment prevent early identification of children suspected of having autism spectrum disorder. We evaluated the benefit of embedded diagnostic consultation within primary care clinics. Using a streamlined diagnostic model, 119 children with concerns for autism spectrum disorder were seen over 14 months. Diagnostic clarity was determined through streamlined assessment for 59% of the children, while others required follow-up. Latency from first concern to diagnosis was 55 days and median age at diagnosis was 32 months: considerably lower than national averages or comparable tertiary clinics. Findings support that embedded processes for effective triage and diagnosis within the medical home is a viable mechanism for efficient access to diagnostic services and assists in bypassing a common barrier to specialized services. PMID- 29589273 TI - Children with Autism Spectrum Disorder Prefer Looking at Repetitive Movements in a Preferential Looking Paradigm. AB - The present study aimed to investigate the visual preference for repetitive movements in children with autism spectrum disorder (ASD). Young children with ASD and typically-developing (TD) children were presented simultaneously with cartoons depicting repetitive and random movements respectively, while their eye movements were recorded. We found that: (1) the children with ASD spent more time fixating on the repetitive movements than the random movements, whereas the TD children showed no preference for either type of movements; (2) the children's preference for the repetitive movements was correlated with the parent reports of their repetitive behaviors. Our findings show a promise in using the preferential looking as a potential indicator for the repetitive behaviors and aiding early screening of ASD in future investigations. PMID- 29589274 TI - Additive Effect of Variably Penetrant 22q11.2 Duplication and Pathogenic Mutations in Autism Spectrum Disorder: To Which Extent Does the Tree Hide the Forest? AB - The 22q11.2 duplication is a variably penetrant copy number variant (CNV) associated with a broad spectrum of clinical manifestations including autism spectrum disorders (ASD), and epilepsy. Here, we report on pathogenic HUWE1 and KIF1A mutations in two severely affected ASD/ID participants carrying a 22q11.2 duplication. Based on previous studies, this CNV was originally considered as disease-causing. Yet, owing to their clinical severity, the participants were further investigated by next generation sequencing and eventually found to carry pathogenic mutations in HUWE1 and KIF1A respectively. We suggest giving consideration to additive effect of 22q11.2 duplication and pathogenic mutations when clinical presentation is either unusually severe or associated with atypical features. Caution should be exercised when delivering genetic counseling for variably penetrant CNVs, as uncertain penetrance of this CNV may lead to ignore additive pathogenic mutations. Systematic panel or exome sequencing of known ASD genes should be recommended when counseling families of patients carrying variably penetrant CNV. PMID- 29589275 TI - Surprising origin of two carved bones donated to the Buchenwald Memorial Museum. AB - Unidentified bones were donated to the Buchenwald Memorial Museum in Weimar, Germany. The donor thought the bones may have belonged to internees of the concentration camp and had been decoratively carved by camp personnel. Non destructive forensic anthropological examination was carried out on the bones to identify their possible origin. Comparative human and non-human bones samples were used to determine the provenance of the bones and the anatomical region they may have come from. Literature and internet searches were conducted to trace the origin of the carved motifs on the bones. The bones were determined to belong to the lower limb region of bovids. The carvings were found to correspond with those of existing bone examples found in some museums in the UK. They were traced to German prisoners of war dating to the First World War. An in-depth examination of the donated bones revealed their non-human provenance. It further showed that no link existed between the bones, internees of the concentration camp, and the time of the camp's existence. It was discovered that they belonged to the period 1914 1918 and form an important part of German prisoner of war history in the UK. PMID- 29589277 TI - Effects of Microencapsulated Saccharomyces cerevisiae on Growth, Hematological Indices, Blood Chemical, and Immune Parameters and Intestinal Morphology in Striped Catfish, Pangasianodon hypophthalmus. AB - This study investigated the effects of dietary probiotic Saccharomyces cerevisiae in the striped catfish, Pangasianodon hypophthalmus, which is an important aquaculture species. Freeze-dried microencapsulated probiotic S. cerevisiae with guar gum was performed and used for fish feed supplementation. Striped catfish were fed for 120 days with one of three experimental diets: basal diet (control), basal diet supplemented with 106-CFU S. cerevisiae g-1 diet (S. cerevisiae 106), and basal diet supplemented with 108-CFU S. cerevisiae g-1 diet (S. cerevisiae 108). The S. cerevisiae-supplemented diets significantly improved growth performance including growth rate and feed conversion ratio over 120 days of culture period (P < 0.05). The rate of survival was similar in all experimental groups. Supplementation with S. cerevisiae did not significantly affect whole body proximate composition (P > 0.05). In addition, probiotic S. cerevisiae had no effects on hematological indices and blood chemistry values (glucose, cholesterol, triglycerides, protein, albumin, blood urea nitrogen, chloride, calcium, magnesium, iron, and phosphorus) (P > 0.05). However, dietary S. cerevisiae led to increases in humoral immune parameters including total immunoglobulin, lysozyme, and alternative complement activities (P < 0.05). Dietary S. cerevisiae led to increase intestinal villus height in the anterior part of intestine (P < 0.05). Taken together, while the dietary S. cerevisiae had no detectable effects on hematological indices and several metabolic indicators, significant beneficial probiotic effects were observed on rates of growth, feed conversion ratio, and immune parameters. PMID- 29589276 TI - Dipentylammonium Binds to the Sigma-1 Receptor and Protects Against Glutamate Toxicity, Attenuates Dopamine Toxicity and Potentiates Neurite Outgrowth in Various Cultured Cell Lines. AB - Alzheimer's disease is a neurodegenerative disease that affects 44 million people worldwide, costing the world $605 billion to care for those affected not taking into account the physical and psychological costs for those who care for Alzheimer's patients. Dipentylammonium is a simple amine, which is structurally similar to a number of other identified sigma-1 receptor ligands with high affinities such as (2R-trans)-2butyl-5-heptylpyrrolidine, stearylamine and dodecylamine. This study investigates whether dipentylammonium is able to provide neuroprotective effects similar to those of sigma-1 receptor agonists such as PRE 084. Here we identify dipentylammonium as a sigma-1 receptor ligand with nanomolar affinity. We have found that micromolar concentrations of dipentylammonium protect from glutamate toxicity and prevent NFkappaB activation in HT-22 cells. Micromolar concentrations of dipentylammonium also protect stably expressing amyloid precursor protein Swedish mutant (APP/Swe) Neuro2A cells from toxicity induced by 150 MUM dopamine, suggesting that dipentylammonium may be useful for the treatment of Parkinsonian symptoms in Alzheimer's patients which are often associated with a more rapid deterioration of cognitive and physical ability. Finally, we found that low micromolar concentrations of dipentylammonium could out preform known sigma-1 receptor agonist PRE-084 in potentiating neurite outgrowth in Neuro2A cells, further suggesting that dipentylammonium has a potential use in the treatment of neurodegenerative diseases and could be acting through the sigma-1 receptor. PMID- 29589278 TI - Frailty in Patients With Cirrhosis. AB - PURPOSE OF REVIEW: This review gives an overview of the evolving concept of physical frailty in patients with cirrhosis. As well as summarizing the available metrics that have been used to diagnose it, this review also examines the major recent trials that have investigated frailty in patients with cirrhosis. The complex relationship between sarcopenia and frailty is explored, and strategies to optimize frailty, such as including pharmacological and non-pharmacological therapies, are discussed. RECENT FINDINGS: Though there is heterogeneity between studies on how physical frailty in cirrhosis has been assessed, it is nonetheless becoming increasingly apparent that frailty in cirrhosis contributes to poor outcomes. A growing body of evidence strongly supports that frailty, as an entity distinct from comorbidity or measurable by laboratory-based liver disease severity, contributes to pre-transplant mortality and unplanned hospital admissions. If taken into account, frailty may improve pre-transplant mortality risk prediction. Physical frailty in cirrhosis may be objectively assessed by a number of validated metrics though at present, we lack a uniform consensus on the most appropriate tool. Early identification of frailty may allow optimization of the patient with the potential to avoiding adverse outcomes. Further studies are awaited validating and exploring optimal approaches to diagnosing and reversing frailty. PMID- 29589279 TI - Synthesis of Lactosucrose Using a Recombinant Levansucrase from Brenneria goodwinii. AB - Lactosucrose is a kind of trisaccharide that functions as a significant prebiotic in the maintenance of gastrointestinal homeostasis for human. In this study, a levansucrase from Brenneria goodwinii was further used for the lactosucrose production. The recombinant levansucrase showed efficiency in the lactosucrose production by transfructosylation from sucrose and lactose, and no other oligosaccharide or polysaccharide was detected in the reaction mixture. The transfructosylation product by this recombinant enzyme was structurally determined to be lactosucrose by FT-IR and NMR. The production condition was optimized as pH at 6.0, temperature at 35 degrees C, 5 U mL-1 enzyme, 180 g L-1 sucrose, and 180 g L-1 lactose. Under the optimal condition, the enzyme could approximately produce 100 g L-1 lactosucrose when the reaction reached equilibrium. The recombinant levansucrase could effectively and exclusively catalyze the formation of lactosucrose, which might expand the enzymatic choice for further preparation of lactosucrose. PMID- 29589280 TI - Response to cyclosporine A and corticosteroids in adult patients with acquired pure red cell aplasia: serial experience at a single center. AB - To assess response to cyclosporine A, and/or corticosteroids, and possible factors influencing the response in adult patients with acquired pure red cell aplasia (PRCA). Clinical data from 42 cases were retrospectively analyzed. These patients received cyclosporine A (CsA), and/or corticosteroids (CS), or other immunosuppressive agents on becoming refractory and relapse. Thirty-nine patients were evaluated. Remission induction therapy included CsA (n = 16), CS (n = 13), CsA in combination with CS (n = 6), or other immunosuppressive agents (n = 4). Initial response rates were 75.0, 46.2, 66.7 and 75.0%, respectively (P = 0.456). Cumulative response rates in patients who received CsA, CS, CsA in combination with CS, or other immunosuppressive agents were 69.6% (16/23), 50.0% (7/14), 71.4% (5/7), 42.9% (6/14), respectively (P = 0.376). Cumulative rates of CR were 26.1% (6/23), 28.6% (4/14), 57.1% (4/7), 14.3% (2/14), respectively (P = 0.284). In 27 refractory and relapsed PRCA patients, 11 of 17 patients (64.7%) achieved remission by CsA and/or CS regimen, while three of ten patients (30.0%) responded to other immunosuppressive agents (P = 0.120). CsA and/or CS were effective in treating PRCA. For patients with relapse or refractory PRCA, there were no satisfactory treatments if CsA and/or CS failed or were not administered.

AB - Mating behavior in males and females is dependent on olfactory cues processed through both the main olfactory epithelium (MOE) and the vomeronasal organ (VNO). Signaling through the MOE is critical for the initiation of male mating behavior, and the loss of MOE signaling severely compromises this comportment. Here, we demonstrate that dosage of the homeodomain gene Six3 affects the degree of development of MOE but not the VNO. Anomalous MOE development in Six3 heterozygote mice leads to hyposmia, specifically disrupting male mounting behavior by impairing detection of volatile female estrus pheromones. Six3 is highly expressed in the MOE, main olfactory bulb (MOB), and hypothalamus; all regions essential in the proper migration of the gonadotropin-releasing hormone (GnRH) neurons, a key reproductive neuronal population that migrates along olfactory axons from the developing nose into the brain. Interestingly, we find that the reduction in Six3 expression in Six3 heterozygote mice compromises development of the MOE and MOB, resulting in mis-migration of GnRH neurons due to improper olfactory axon targeting. This reduction in the hypothalamic GnRH neuron population, by 45% in adulthood, leads to female subfertility, but does not impact male hormone levels, suggesting that male infertility is not related to GnRH neuron numbers, but exclusively linked to abnormal olfaction. We here determine that Six3 is haploinsufficient for MOE development, GnRH neuron migration, and fertility, and represents a novel candidate gene for Kallmann syndrome, a form of inherited infertility. PMID- 29589283 TI - Detecting Alpha Synuclein Seeding Activity in Formaldehyde-Fixed MSA Patient Tissue by PMCA. AB - Alpha synuclein (alpha-syn) is central to the pathogenesis of a group of neurodegenerative disorders known as synucleinopathies, including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). Aggregation of alpha-syn is the pathologic hallmark of these disorders and is intimately associated with the pathogenic changes. The prion-like hypothesis postulates that the aggregated alpha-syn provides a template to seed the aggregation of normal alpha-syn and spread the pathology. Thus far, it remains unclear whether aggregated alpha-syn can be a useful biomarker for diagnosis and/or tracking disease progression, which is mainly due to the lack of a suitable biochemical assay. The protein misfolding cyclic amplification (PMCA) technique is known for its enormous amplification power to detect the seeding activity of protein aggregates such as prions. In this study, we adapted PMCA for detecting the seeding activity of alpha-syn. By extensively optimizing the PMCA parameters, we developed a protocol that is able to sensitively and quantitatively detect the seeding activity of as little as 100 attomoles (10-16 mol) of alpha-syn aggregate. Using our protocol, we detected alpha-syn seeding activity from a histologically positive, formaldehyde-fixed MSA sample, but not with the histologically negative, formaldehyde-fixed control sample. Our results confirmed that the alpha-syn in MSA patient's brain does contain seeding activity, which remains active even after fixation. Moreover, we also established that PMCA with sonication is a sensitive and quantitative method for detecting alpha-syn seeding activity, which can be further adapted to more accessible patients' samples to evaluate alpha-syn aggregates as a biomarker for synucleinopathies. PMID- 29589281 TI - Treatment outcome of children with acute lymphoblastic leukemia: the Tokyo Children's Cancer Study Group (TCCSG) Study L04-16. AB - The survival rate of children with acute lymphoblastic leukemia (ALL) has increased to approximately 90% after substantial progress in risk-oriented treatment strategies. Between 2005 and 2013, the Tokyo Children's Cancer Study Group (TCCSG) conducted a risk-oriented, non-randomized study, L04-16. The principal aim of this study was to assemble background characteristics and treatment outcomes, and gather genetic information on leukemic cells under central diagnosis. This report outlines the background characteristics and treatment outcomes of 1033 children with ALL treated according to a TCCSG platform. The 5-year event-free and overall survival (OS) rates for all children were 78.1 +/- 1.3 and 89.6 +/- 1.0%, respectively. The OS rate was significantly higher in children with B-cell precursor (BCP)-ALL (91.9 +/- 1.0%, n = 916) than in those with T-ALL (71.9 +/- 4.3%, n = 117, p < 0.001). In univariate analysis for BCP-ALL, children aged 1-6 years (5y-OS: 94.2 +/- 1.0%), with an initial white blood cell count of < 20,000/MUL (94.0 +/- 1.0%), high hyperdiploidy (95.4 +/- 1.6%), ETV6-RUNX1 (97.4 +/- 1.2%) or TCF3-PBX1 (96.9 +/- 2.1%), and "Day8NoBlasts" (96.4 +/- 1.1%) had the best outcomes. Genetic investigation revealed two novel fusion genes within this cohort: ETV6-ZNF385A and ZNF362-TCF4. Our study highlighted the clinical aspects of genomic features of ALL in Japanese children. We provide fundamental information for the further molecular investigation of this disease. PMID- 29589285 TI - Hematologic Markers of Lung Metastasis in Stage IV Colorectal Cancer. AB - BACKGROUND: Many studies showed an association between absolute neutrophil count (ANC), absolute monocyte count (AMC), neutrophil-lymphocyte ratio (NLR), monocyte lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) with poor overall survival (OS) in patients with cancer. However, only a few studies were conducted to further investigate this association in colorectal cancer (CRC). METHODS: Clinical data from 299 stage IV CRC patients treated at King Hussein Cancer Center from 2004 to 2012 have been retrospectively reviewed. We examined the association between ANC, AMC, MLR, PLR, and NLR with lung metastasis in stage IV CRC. Receiver Operating Characteristic (ROC) curve analysis was operated to determine the optimal NLR cutoff value. Univariate and multivariate analysis were performed. RESULTS: The ROC value of 3.4 was determined as the cutoff value of NLR to study the association. Univariate and multivariate analysis showed that patients with high baseline NLR (>= 3.4) had more baseline lung metastasis than patients with low NLR (< 3.4) (p = 0.0001, p = 0.0151, respectively). Also, baseline NLR correlated significantly with the presence of lymphovascular invasion (p = 0.001). In patients with no baseline lung metastasis, high post treatment NLR was associated with consequent development of lung metastasis (p = 0.0227). Other markers including ANC, AMC, MLR, and PLR were significantly associated with lung metastasis at time of diagnosis (p = 0.0006, p = 0.0006, p = 0.0187, and p = 0.001, respectively). CONCLUSION: Results are suggesting that different hematologic markers obtained from a cheap test (CBC) could potentially be used to predict the likelihood of lung metastasis in stage IV CRC. Prospective studies are needed to further assess the immune cells' role in tumor metastasis promotion. PMID- 29589286 TI - Genetic and Environmental Contributions to Variation in the Posterior Communicating Collaterals of the Circle of Willis. AB - Variation in blood flow mediated by the posterior communicating collateral arteries (PComs) contributes to variation in the severity of tissue injury in obstructive disease. Evidence in animals and humans indicates that differences in the extent of PComs, i.e., their anatomic lumen diameter and whether they are present bilaterally, unilaterally, or absent, are a major factor. These differences arise during development since they are present at birth. However, the causal mechanisms are unknown. We used angiography after maximal dilation to examine involvement of genetic, environmental, and stochastic factors. The extent of PComs varied widely among seven genetically diverse strains of mice. Like pial collaterals in the microcirculation, aging and hypertension reduced PCom diameter, while in contrast, obesity, hyperlipidemia, metabolic syndrome, and diabetes mellitus had no effect. Naturally occurring intrauterine growth restriction had no effect on extent of PCom or pial collaterals in the adult. The number and diameter of PComs evidenced much larger apparent stochastic-dependent variation than pial collaterals. In addition, both PComs underwent flow-mediated outward remodeling after unilateral permanent MCA occlusion that varied with genetic background and was greater on the ipsilesional side. These findings indicate that variation in the number and diameter of PCom collateral arteries arises from stochastic factors and naturally occurring genetic variants that differ from those that cause variation in pial collateral arterioles. Environmental factors also contribute: aging and hypertension reduce PCom diameter. Our results suggest possible sources of variation of PComs in humans and provide information relevant when studying mouse models of occlusive cerebrovascular disease. PMID- 29589284 TI - Hypoxia-Induced Neuroinflammation and Learning-Memory Impairments in Adult Zebrafish Are Suppressed by Glucosamine. AB - This study investigated changes in neuroinflammation and cognitive function in adult zebrafish exposed to acute hypoxia and protective effects of glucosamine (GlcN) against hypoxia-induced brain damage. The survival rate of zebrafish following exposure to hypoxia was improved by GlcN pretreatment. Moreover, hypoxia-induced upregulation of neuroglobin, NOS2alpha, glial fibrillary acidic protein, and S100beta in zebrafish was suppressed by GlcN. Hypoxia stimulated cell proliferation in the telencephalic ventral domain and in cerebellum subregions. GlcN decreased the number of bromodeoxyuridine (BrdU)-positive cells in the telencephalon region, but not in cerebellum regions. Transient motor neuron defects, assessed by measuring the locomotor and exploratory activity of zebrafish exposed to hypoxia recovered quickly. GlcN did not affect hypoxia induced motor activity changes. In passive avoidance tests, hypoxia impaired learning and memory ability, deficits that were rescued by GlcN. A learning stimulus increased the nuclear translocation of phosphorylated cAMP response element binding protein (p-CREB), an effect that was greatly inhibited by hypoxia. GlcN restored nuclear p-CREB after a learning trial in hypoxia-exposed zebrafish. The neurotransmitters, gamma-aminobutyric acid and glutamate, were increased after hypoxia in the zebrafish brain, and GlcN further increased their levels. In contrast, acetylcholine levels were reduced by hypoxia and restored by GlcN. Acetylcholinesterase inhibitor physostigmine partially reversed the impaired learning and memory of hypoxic zebrafish. This study represents the first examination of the molecular mechanisms underlying hypoxia-induced memory and learning defects in a zebrafish model. Our results further suggest that GlcN associated hexosamine metabolic pathway could be an important therapeutic target for hypoxic brain damage. PMID- 29589287 TI - Waist circumference is a better predictor of risk for frailty than BMI in the community-dwelling elderly in Beijing. AB - AIM: Obesity is found to be associated with frailty. Body mass index (BMI) and waist circumference (WC) are the commonly used measures for obesity, the former is more closely related to general obesity and body weight; the latter can more accurately reflect abdominal obesity and is more closely associated with metabolic disorders. In this study, we intend to study the relationship between frailty, BMI and WC among older people. METHODS: Data were derived from the Beijing Longitudinal Study on Aging II Cohort, which included 6320 people 65 years or older from three urban districts in Beijing. A Frailty Index derived from 33 items was developed according to Rockwood's cumulative deficits method. A Frailty Index >= 0.25 was used as the cut-off criteria. BMI was classified as underweight, normal, overweight, or obese (< 18.5, 18.5-< 24.0, 24.0-27.9, >= 28.0 kg/m2, respectively). High WC was defined as WC >= 85 cm in men and >= 80 cm in women. RESULTS: People with a larger BMI (>= 28.0 kg/m2, 22.6%) or a larger WC (18.5%) were more likely to be frail. People with normal BMI and overweight people do not suffer from higher prevalence for frailty. In comparison with individuals with normal BMI (18.5-< 24.0 kg/m2) and normal WC (< 85 cm in men, <80 cm in women), the risk of frailty was higher among individuals who have normal BMI and large WC (odds ratio 1.68; 95% CI 1.33-2.12), have overweight and large WC (odds ratio 1.58; 95% CI 1.23-1.96), or have obesity and large WC (odds ratio 2.28; 95% CI 1.79-2.89). In people with normal WC, only those who are underweight have a higher risk for frailty (odds ratio 1.65, 95% CI 1.08-2.52). In comparison with BMI, the relation of WC with the risk for frailty was much closer. CONCLUSIONS: Abdominal obesity is more closely associated with incidence of frailty than general obesity in the elderly. Older adults with large waist circumference are more likely to be frail. Frailty in the elderly might be more closely related to metabolic disorders. WC might be a better measurement to detect frailty than BMI, given its relationship with metabolic disorders.

PMID- 29589289 TI - The relative merit of empirical priors in non-identifiable and sloppy models: Applications to models of learning and decision-making : Empirical priors. AB - Formal modeling approaches to cognition provide a principled characterization of observed responses in terms of a set of postulated processes, specifically in terms of parameters that modulate the latter. These model-based characterizations are useful to the extent that there is a clear, one-to-one mapping between parameters and model expectations (identifiability) and that parameters can be recovered from reasonably sized data using a typical experimental design (recoverability). These properties are sometimes not met for certain combinations of model classes and data. One suggestion to improve parameter identifiability and recoverability involves the use of "empirical priors", which constrain parameters according to a previously observed distribution of values. We assessed the efficacy of this proposal using a combination of real and artificial data. Our results showed that a point-estimate variant of the empirical-prior method could not improve parameter recovery systematically. We identified the source of poor parameter recovery in the low information content of the data. As a follow up step, we developed a fully Bayesian variant of the empirical-prior method and assessed its performance. We find that even such a method that takes the covariance structure of the parameter distributions into account cannot reliably improve parameter recovery. We conclude that researchers should invest additional efforts in improving the informativeness of their experimental designs, as many of the problems associated to impoverished designs cannot be alleviated by modern statistical methods alone. PMID- 29589290 TI - HTLV-1 proviral load in cerebrospinal fluid may not be a good marker to differentiate asymptomatic carriers with high proviral load in blood from HAM/TSP patients. AB - An elevated human T cell leukemia virus type 1 (HTLV-1) proviral load (PVL) is an important risk factor for HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), although there is a considerable frequency of asymptomatic carriers (AC) with high PVL in blood. Our objective was to evaluate whether PVL quantified in cerebrospinal fluid (CSF) is helpful to distinguish AC from HAM when AC have high PVL in blood (ACH). ACH (n = 7) were characterized to have high PVL in blood by quantification of samples collected over time (mean 7 years). HAM patients (n = 14) also had analyzed blood samples collected at different times (mean 9 years). Comparing paired CSF and blood samples of each individual, CSF PVL mean was 4.7-fold higher than blood PVL in the ACH group and 10.8-fold in the HAM group. CSF PVL was significantly greater than blood PVL in the HAM group (p = 0.004), but not in the ACH group. Important to highlight, CSF PVL was not significantly different between the ACH and the HAM groups. These results suggested that significantly higher PVL in CSF than in blood is a hallmark of HAM/TSP patients, but this is also true for asymptomatic carriers with high PVL in blood, thus reducing its usefulness as a marker for HAM/TSP. A greater number of ACH should be analyzed, but whether they will eventually develop HAM/TSP or why they have not developed the disease are still questions to be clarified. Longitudinal studies are necessary to answer these questions. PMID- 29589291 TI - Modelling Movement Energetics Using Global Positioning System Devices in Contact Team Sports: Limitations and Solutions. AB - Quantifying the training and competition loads of players in contact team sports can be performed in a variety of ways, including kinematic, perceptual, heart rate or biochemical monitoring methods. Whilst these approaches provide data relevant for team sports practitioners and athletes, their application to a contact team sport setting can sometimes be challenging or illogical. Furthermore, these methods can generate large fragmented datasets, do not provide a single global measure of training load and cannot adequately quantify all key elements of performance in contact team sports. A previous attempt to address these limitations via the estimation of metabolic energy demand (global energy measurement) has been criticised for its inability to fully quantify the energetic costs of team sports, particularly during collisions. This is despite the seemingly unintentional misapplication of the model's principles to settings outside of its intended use. There are other hindrances to the application of such models, which are discussed herein, such as the data-handling procedures of Global Position System manufacturers and the unrealistic expectations of end users. Nevertheless, we propose an alternative energetic approach, based on Global Positioning System-derived data, to improve the assessment of mechanical load in contact team sports. We present a framework for the estimation of mechanical work performed during locomotor and contact events with the capacity to globally quantify the work done during training and matches. PMID- 29589293 TI - The effect of day 2 versus day 3 embryo transfer on early pregnancy outcomes in women with a low yield of fertilized oocytes. AB - PURPOSE: To evaluate the differences in implantation and pregnancy rates when embryo transfer occurs on D2 versus D3 in women with a low yield of fertilized oocytes. METHODS: A total of 156 IVF/ICSI cycles from 141 women at an academic fertility center were analyzed in a retrospective fashion. Women with a low number of fertilized oocytes (<= 2 two pronuclei (2PN) stage zygotes) who had their fresh embryo transfer on D2 or D3 were included in the study. Positive pregnancy test per IVF cycle (PPT), clinical pregnancy rate (CPR), spontaneous abortion rate (SABR), and implantation rate (IMPR) were the main outcome measures assessed. Mann-Whitney U test and chi2 test were used as appropriate. A generalized linear mixed effect model adjusted for relevant covariates was conducted. P < 0.05 was considered significant. RESULTS: Patients having their embryo transfer on D2, when compared to those who had a D3 embryo transfer, experienced similar PPT [30.8 vs. 28.2%, respectively; adjusted OR (95%CI): 0.49 (0.16, 1.52)], CPR [26.9 vs. 25.6%, respectively; adjusted OR (95%CI): 0.44 (0.12, 1.67)], and IMPR [17.3 vs. 16.7%, respectively; adjusted beta (95%CI) - 5.6% (- 15.0, 3.9)]. CONCLUSION: Our findings suggest that transferring embryos on D2 versus D3 in women with a limited number of 2PN stage zygotes does not affect early pregnancy outcomes. These results indicate that there can be some flexibility in scheduling the day of transfer at the convenience of both the patient and the center. PMID- 29589294 TI - Examination of the ovotoxicity of 5-fluorouracil in mice. AB - PURPOSE: Undesirable side effects of cancer treatments are common and include damage to the ovary, and depletion of the follicle reserve, which if severe enough, can lead to infertility and early menopause. Antimetabolite drugs, such as 5-fluorouracil (5-FU), are not considered to be detrimental to the ovary, but the ovotoxicity of 5-FU has not been evaluated in any detail. The purpose of this study was to evaluate the effects of 5-FU on follicle number. METHODS: In this study, adult female C57Bl6 mice (n = 4-6 animals/group) received a single dose of saline or 5-FU (150 mg/kg) and markers of ovarian damage and follicle depletion were assessed 12 h and 7 days later. RESULTS: Exposure to 5-FU did not alter primordial and primary follicle numbers. Atresia of secondary and antral follicles was increased significantly 12 h after 5-FU treatment, but atresia rates returned to levels similar to that of saline treated controls at 7 days. The number of corpora lutea were reduced 7 days after exposure to 5-FU, possibly as a consequence of earlier follicular atresia. CONCLUSIONS: These findings suggest that a single dose of 5-FU is mildly ovotoxic, but any effects on ovarian function are likely transient because the primordial follicle population is not depleted. Collectively, these data support the notion that 5-FU is unlikely to impact on the long-term fertility of women. PMID- 29589292 TI - Adherence to Antidepressants and Mortality in Elderly Patients with Cardiovascular Disease. AB - : BACKGROUND AND OBJECTIVE: Conflicting findings from studies evaluating the association between use of antidepressant drugs and mortality have been reported. We tested the hypothesis that better adherence to antidepressant therapy may reduce mortality. METHODS: The cohort included 29,845 individuals aged >= 65 years from several Italian health units who were newly treated with antidepressant drugs after hospital discharge with a diagnosis for cardiovascular disease during 2008-2010. These individuals were observed from the first prescription until the end of data availability (i.e. 2012-2014, depending on the local database). During this period, information on (1) prescription of antidepressants and other medications and (2) death from any cause (outcome) was recorded. Proportional hazards models were fitted to estimate the association between better adherence to antidepressants (defined as proportion of days covered >= 75%) and outcome, by adjusting and stratifying for several covariates. RESULTS: Patients with better adherence to antidepressants had a reduced mortality of 9% (95% CI 3-14). Patients who did not use other medicaments during follow-up had reduced mortality associated with better adherence to antidepressants of 21% (- 1-38), 14% (7-20), 20% (13-26) and 13% (7-19) for no users of antihypertensive agents, lipid-lowering agents, other cardiovascular drugs and antidiabetics, respectively. CONCLUSIONS: Better adherence to antidepressants is associated with reduced all-cause mortality, mainly in patients who did not use other pharmacological treatments. Behavioural changes to enhance adherence among the elderly with cardiovascular disease might offer important benefits in reducing their mortality. PMID- 29589295 TI - The varicocele argument resurfaces. AB - A recent series of articles and reviews published in Fertility and Sterility have rekindled the more than half century debate on varicocelectomy. Every one of these articles favored strongly the repair of varicocele for male infertility. Since my review paper on this issue in 2001, published in Human Reproduction Update, and since advent of ICSI in 1993, I had thought that most reproductive physicians felt negatively about the benefit of varicocelectomy. However, more recent urological papers are causing this negative view to be re-evaluated. It is now advocated by some urologists that varicocelectomy improves sperm count and testosterone levels, and even improves the results with ICSI. Thus, it may be appropriate to revisit older studies again and review the newer ones in this never ending controversy. Newer studies are re-opening the door to review and possibly re-instate varicocelectomy. This dilemma may never be fully resolved, but it is important to keep an open mind. PMID- 29589296 TI - Understanding Treatment Effect Estimates When Treatment Effects Are Heterogeneous for More Than One Outcome. AB - BACKGROUND: Patient-centred care requires evidence of treatment effects across many outcomes. Outcomes can be beneficial (e.g. increased survival or cure rates) or detrimental (e.g. adverse events, pain associated with treatment, treatment costs, time required for treatment). Treatment effects may also be heterogeneous across outcomes and across patients. Randomized controlled trials are usually insufficient to supply evidence across outcomes. Observational data analysis is an alternative, with the caveat that the treatments observed are choices. Real world treatment choice often involves complex assessment of expected effects across the array of outcomes. Failure to account for this complexity when interpreting treatment effect estimates could lead to clinical and policy mistakes. OBJECTIVE: Our objective was to assess the properties of treatment effect estimates based on choice when treatments have heterogeneous effects on both beneficial and detrimental outcomes across patients. METHODS: Simulation methods were used to highlight the sensitivity of treatment effect estimates to the distributions of treatment effects across patients across outcomes. Scenarios with alternative correlations between benefit and detriment treatment effects across patients were used. Regression and instrumental variable estimators were applied to the simulated data for both outcomes. RESULTS: True treatment effect parameters are sensitive to the relationships of treatment effectiveness across outcomes in each study population. In each simulation scenario, treatment effect estimate interpretations for each outcome are aligned with results shown previously in single outcome models, but these estimates vary across simulated populations with the correlations of treatment effects across patients across outcomes. CONCLUSIONS: If estimator assumptions are valid, estimates across outcomes can be used to assess the optimality of treatment rates in a study population. However, because true treatment effect parameters are sensitive to correlations of treatment effects across outcomes, decision makers should be cautious about generalizing estimates to other populations. PMID- 29589297 TI - Clinical Impact of p27Kip1 and CaSR Expression on Primary Hyperparathyroidism. AB - We aimed to investigate the expressions of p27 kinase inhibitory protein 1 (p27Kip1) and calcium sensing receptor (CaSR) in adenomas and normal parathyroid tissue and to evaluate the relationship of these molecules with clinical and biochemical parameters in primary hyperparathyroidism (PHPT). Fifty-one patients with histopathologically confirmed parathyroid adenomas and 20 patients with normal parathyroid glands (which were removed incidentally during thyroid resection) were included. Immunohistochemical stainings of CaSR and p27Kip1 were performed in surgical specimens. Clinical features, biochemical parameters, and BMD measurements of patients with PHPT were evaluated retrospectively. Expressions of p27Kip1 and CaSR were decreased in parathyroid adenomas, compared to normal glands (p < 0.05). High intensity of CaSR staining (3+) was more frequent in normal parathyroid tissue (75%) than adenomas (12%) (p < 0.01). Hypertension was not observed in patients with high staining intensity of CaSR (p = 0.032). There was a negative association between CaSR expression and body mass index (BMI) (p = 0.027, r = - 0.313). There was no significant relationship between p27Kip1 and CaSR expressions, serum calcium, plasma parathormone, 25 hydroxy vitamin D levels, and bone density (p > 0.05). The expressions of p27Kip1 and CaSR were decreased in PHPT patients. This reduction may play an important role in the pathogenesis of PHPT. However, neither p27Kip1 nor CaSR expression was found to be useful in predicting prognosis or severity of disease. PMID- 29589298 TI - Cell Line Models of Molecular Subtypes of Colorectal Cancer. AB - Colorectal cancer (CRC) is a genetically diverse disease necessitating the need for well-characterized and reproducible models to enable its accurate investigation. Recent genomic analyses have confirmed that CRC cell lines accurately retain the key genetic alterations and represent the major molecular subtypes of primary CRC, underscoring their value as powerful preclinical models. In this chapter we detail the important issues to consider when using CRC cell lines, the techniques used for their appropriate molecular classification, and the methods by which they are cultured in vitro and as subcutaneous xenografts in immune-compromised mice. A panel of commonly available CRC cell lines that have been characterized for key molecular subtypes is also provided as a resource for investigators to select appropriate models to address specific research questions. PMID- 29589299 TI - Dissecting Oncogenic RTK Pathways in Colorectal Cancer Initiation and Progression. AB - Colorectal cancer (CRC) is a progressive disorder associated with an accumulation of multiple heterogeneous genetic alterations in intestinal epithelial cells (IEC). However, when these cells undergo neoplastic transformation and become cancerous and metastatic, they invariably acquire hallmarks conferring them the ability to hyperproliferate, escape growth-inhibitory and death-inducing cues, and promote angiogenesis as well as epithelial-to-mesenchymal transformation (EMT), fostering their invasive dissemination from primary tumor into distant tissues. Compelling clinical and experimental evidence suggest that aberrant engagement of cell surface growth factor receptor tyrosine kinase (RTK) signaling, like that of the hepatocyte growth factor (HGF)/MET receptor, underlies CRC metastatic progression by promoting these cancer hallmarks. To date, though, the use of RTK-targeting agents has been viewed as a promising approach for the treatment of metastatic CRC, clinical success has been modest.Our vision is that the prospect of designing RTK-based, improved and innovative CRC therapies and prognostic markers likely rests on a comprehensive understanding of the biological processes and underlying regulatory molecular mechanisms by which deregulation of RTK signaling governs IEC's neoplastic transformation and their transition from noninvasive to metastatic and malignant cells. Herein, we describe our scheme for defining the full scope of oncogenic MET-driven cancer biological processes, in cellulo and in vivo, as well as the individual contribution of MET-binding effectors in a nontransformed IEC model, the IEC-6 cell line.

AB - Proximal promoters are located upstream of the transcription start sites of genes, and they contain regulatory sequences on which bind different transcription factors for promoting colorectal cancer progression. Here we describe the comprehensive methodology used previously for the identification and functional characterization of MYC-responsive elements in the integrin alpha1 subunit (ITGA1) gene using a combination of in silico analysis, site-directed mutagenesis, and chromatin immunoprecipitation. PMID- 29589301 TI - Identification and Functional Analysis of Gene Regulatory Sequences Interacting with Colorectal Tumor Suppressors. AB - Several tumor suppressors possess gene regulatory activity. Here, we describe how promoter and promoter/enhancer reporter assays can be used to characterize a colorectal tumor suppressor proteins' gene regulatory activity of possible target genes. In the first part, a bioinformatic approach to identify relevant gene regulatory regions of potential target genes is presented. In the second part, it is demonstrated how to prepare and carry out the functional assay.We explain how to clone the bioinformatically identified gene regulatory regions into luciferase reporter plasmids by the use of the quick and efficient In-Fusion cloning method, and how to carry out transient transfections of Caco-2 colon cancer cells with the produced luciferase reporter plasmids using polyethyleneimine (PEI). A plan describing how to set up and carry out the luciferase expression assay is presented. The luciferase/beta-galactosidase (Dual Light) assay presented is a highly sensitive assay that can monitor small changes in the promoter/enhancer activity and includes an internal control monitoring transfection efficiency. PMID- 29589302 TI - Methods for In Vivo Functional Studies of Chromatin-Modifying Enzymes in Early Steps of Colon Carcinogenesis. AB - Since chromatin-modifying enzymes are involved in most processes needing to access the DNA fiber such as transcription, replication or DNA repair, their involvement in the regulation of gene expression in numerous physiopathological contexts is widely studied. Most of these enzymes are essential for cell growth and survival due to their pleiotropic roles and studying their impact in vivo on organ development or tissue physiopathology is challenging. In this chapter, we describe a chemically-mediated method to induce colorectal carcinogenesis that we have used to identify in vivo the role of two chromatin modifying enzymes belonging to the same multimolecular complex, the histone acetyltransferase Tip60 and the histone variant-incorporating ATPase p400. PMID- 29589304 TI - Methods for Assessing Apoptosis and Anoikis in Normal Intestine/Colon and Colorectal Cancer. AB - Caspase-dependent apoptosis, including its distinct cell death subroutine known as anoikis, perform essential roles during organogenesis, as well as in the maintenance and repair of tissues. To this effect, the continuous renewal of the human intestinal/colon epithelium is characterized by the exfoliation by anoikis of differentiated cells, whereas immature/undifferentiated cells may occasionally undergo apoptosis in order to evacuate daughter cells that are damaged or defective. Dysregulated epithelial apoptosis is a significant component of inflammatory bowel diseases. Conversely, the acquisition of a resistance to apoptosis represents one of the hallmarks of cancer initiation and progression, including for colorectal cancer (CRC). Furthermore, the emergence of anoikis resistance constitutes a critical step in cancer progression (including CRC), as well as a limiting one that enables invasion and metastasis.Considering the implications of apoptosis/anoikis dysregulation in gut physiopathology, it therefore becomes incumbent to understand the functional determinants that underlie such dysregulation-all the while having to monitor, assess, or evidence apoptosis and/or anoikis. In this chapter, methodologies that are typically used to assess caspase-dependent apoptosis and anoikis in intestinal/colonic normal and CRC cells, whether in vivo, ex vivo, or in cellulo, are provided. PMID- 29589303 TI - The Colorectal Cancer Microenvironment: Strategies for Studying the Role of Cancer-Associated Fibroblasts. AB - Colorectal cancer (CRC) is a key public health concern and the second highest cause of cancer related death in Western society. A dynamic interaction exists between CRC cells and the surrounding tumor microenvironment, which can stimulate not only the development of CRC, but its progression and metastasis, as well as the development of resistance to therapy. In this chapter, we focus on the role of fibroblasts within the CRC tumor microenvironment and describe some of the key methods for their study, as well as the evaluation of dynamic interactions within this biological ecosystem. PMID- 29589305 TI - Molecular Analysis of the Microbiome in Colorectal Cancer. AB - The human gut microbiota plays a major role in the development of colorectal cancer (CRC). Many studies have attempted to define links between microbiota residents, their function and disease development. We now have incredible molecular tools to allow us to study the gut microbiome however in order to make best use of these sophisticated approaches we need to ensure that samples are collected and processed using standardized and reproducible protocols. Here we provide an overview of molecular analysis methods and describe protocols for collecting and processing clinical samples for subsequent microbiome analysis. PMID- 29589306 TI - Proteomics Analysis of Colorectal Cancer Cells. AB - Proteomics allows the simultaneous detection and identification of thousands of proteins within a sample. Here, we describe a quantitative method to compare protein expression and subcellular localization of different cell lines representative of different stages of colorectal cancer using stable isotope labeling with amino acids in culture, or SILAC. We also describe a biochemical fractionation approach to separate different cellular compartments and the necessary steps to obtain a specific proteomic profile of each cell line. This technique enables a comprehensive proteomic analysis of cancer cell lines and the identification of pathways that are deregulated in different cancer cell lines. PMID- 29589307 TI - Autophagic Flux Assessment in Colorectal Cancer Cells. AB - Autophagy protects colorectal cancer cells against therapeutic intervention. Autophagy is a continuous process, and autophagic flux requires both autophagosome synthesis and their subsequent degradation at lysosomes. Hence, cells with elevated autophagic flux display both rapid autophagosome generation and degradation. Here, we describe an immunoblot protocol coupled to pharmaceutical inhibition of autophagosome clearance to monitor autophagic flux levels between colorectal cancer cell lines. PMID- 29589308 TI - Classification of Colorectal Cancer in Molecular Subtypes by Immunohistochemistry. AB - Colorectal cancer (CRC) is a heterogeneous disease, which can be categorized into distinct consensus molecular subtypes (CMSs). These subtypes differ in both clinical as well as biological properties. The gold-standard classification strategy relies on genome-wide expression data, which hampers widespread implementation. Here we describe an immunohistochemical (IHC) Mini Classifier, a practical tool that, in combination with microsatellite instability testing, delivers objective and accurate scoring to classify CRC patients into the main molecular disease subtypes. It is a robust immunohistochemical-based assay containing four specific stainings (FRMD6, ZEB1, HTR2B, and CDX2) in combination with cytokeratin. We also describe an online tool for classification of individual samples based on scoring parameters of these stainings. PMID- 29589309 TI - Stool DNA Integrity Method for Colorectal Cancer Detection. AB - Fluorescence long DNA (FL-DNA) is a non-invasive and simple-to-perform stool DNA test. This assay consists of a qualitative and quantitative real-time PCR (RT PCR) analysis. FL-DNA has great potential in colorectal cancer (CRC) lesions detection used alone or in combination with the standard CRC screening tool: immunochemical fecal occult blood test (iFOBT). PMID- 29589310 TI - RT-qPCR for Fecal Mature MicroRNA Quantification and Validation. AB - By routinely and systematically being able to perform quantitative stem-loop reverse transcriptase (RT) followed by TaqMan(r) minor-groove binding (MGB) probe, real-time quantitative PCR analysis on exfoliated enriched colonocytes in stool, using human (Homo sapiens, hsa) micro(mi)RNAs to monitor changes of their expression at various stages of colorectal (CRC) progression, this method allows for the reliable and quantitative diagnostic screening of colon cancer (CC). Although the expression of some miRNA genes tested in tissue shows less variability in normal or cancerous patients than in stool, the noninvasive stool by itself is well suited for CC screening. An miRNA approach using stool promises to offer more sensitivity and specificity than currently used genomic, methylomic, or proteomic methods for CC screening.To present an application of employing miRNAs as diagnostic markers for CC screening, we carried out global microarray expression studies on stool colonocytes isolated by paramagnetic beads, using Affymetrix GeneChip miRNA 3.0 Array, to select a panel of miRNAs for subsequent focused semiquantitative PCR analysis studies. We then conducted a stem-loop RT-TaqMan(r) MGB probes, followed by a modified real-time qPCR expression study on 20 selected miRNAs for subsequent validation of the extracted immunocaptured total small RNA isolated from stool colonocytes. Results showed 12 miRNAs (miR-7, miR-17, miR-20a, miR-21, miR-92a, miR-96, miR-106a, miR-134, miR 183, miR-196a, miR-199a-3p, and miR214) to have an increased expression in stool of CC patients, and that later TNM stages exhibited more increased expressions than adenomas, while 8 miRNAs (miR-9, miR-29b, miR-127-5p, miR-138, miR-143, miR 146a, miR-222, and miR-938) showed decreased expressions in stool of CC patients, which becomes more pronounced as the cancer progresses from early to late TNM stages (0-IV). PMID- 29589311 TI - A Stool Multitarget mRNA Assay for the Detection of Colorectal Neoplasms. AB - Noninvasive screening methods for the detection of colorectal cancers (CRC) at curable stages rely on the identification of specific biomarkers. Our group has shown that mRNA stool assays represent a powerful and robust approach for the prediction of colorectal neoplasms. In this methodological chapter, we describe the procedures to isolate good quality stool RNA and the steps to evaluate the levels of specific host mRNA markers such as ITGA6, MYC, and GADD45B using TaqMan based quantitative and droplet digital PCR approaches. PMID- 29589312 TI - Colorectal Cancer Detection Using Targeted LC-MS Metabolic Profiling. AB - Colorectal cancer (CRC) is one of the most commonly diagnosed malignancies and causes of cancer death. While the mortality rates from CRC have steadily declined, 50,000 individuals in the USA (and many times this number worldwide) still succumb to this illness every year. Early detection of CRC is the most critical need for improving 5-year survival and cure rates. Currently available CRC diagnostic techniques often miss early stage disease such that only 40% of newly diagnosed CRC patients are treated for local disease, Therefore, development of new screening methods that are highly sensitive, specific, noninvasive and easily accessible are critically desired for the early diagnosis and significant reduction in death rate from CRC. In this chapter we describe a targeted LC-MS based metabolic profiling approach used for the discovery of CRC metabolite biomarker candidates, based on highly reproducible hydrophilic interaction liquid chromatography coupled to triple-quadrupole mass spectrometry (HILIC-LC-QQQ-MS). A partial least squares-discriminant analysis (PLS-DA) model was able to differentiate CRC patients from both healthy controls and polyp patients, as well as to distinguish CRC patients based on the cancer stage. PMID- 29589313 TI - Proteomic Profiling for Colorectal Cancer Biomarker Discovery. AB - Nowadays, the ideal biomarker for colorectal cancer (CRC) has not been found. Two dimensional electrophoresis (2-DE) and mass spectrometry (MS) are suitable techniques for searching new biomarkers. In this chapter, we describe methodology for biomarker discovery based on a proteomic approach. In addition, special attention is given to the sample preparation, including protein extraction, fractionation, and cleanup, as we consider this a critical step. Comparing the proteomic profile of tumor and mucosa, we identified the nucleoside diphosphate kinase A (NDKA) protein as a candidate biomarker for CRC. Finally, we validated NDKA with an ELISA kit using serum samples from individuals of a screening cohort. Our results suggest that serum NDKA is a potential biomarker for screening of CRC and premalignant advanced adenomas (AA). PMID- 29589314 TI - Tumor-Derived Microparticles to Monitor Colorectal Cancer Evolution. AB - Colorectal cancer is the most common gastrointestinal cancer and the second-most common cause of cancer-related death worldwide. Microparticles are small vesicles known to be implicated in tumor growth, the development of metastases, and cancer associated procoagulant activity. We have reported a specific hallmark of microparticles in colorectal and pancreatic cancers, the so-called "microparticulosome." We have also reported on variations in the microparticulosome in the case of the occurrence of a thromboembolic event. Here, we describe our flow cytometry-based methods for identifying and characterizing tumor-derived microparticles and thereby monitoring colorectal cancer evolution. PMID- 29589315 TI - Molecular Testing for the Treatment of Advanced Colorectal Cancer: An Overview. AB - Concurrent with an expansion in the number of agents available for the treatment of advanced CRC, there has been an increase in our understanding of selection biomarkers to optimize the management of patients with this disease. For CRC patients being considered for anti-EGFR therapy, expanded RAS testing is the standard of care to determine the subset of patients who can benefit from cetuximab or panitumumab in conjunction with chemotherapy. A small fraction of patients have HER2 amplification where emerging data suggest treatment with drugs targeting this alteration. Although advanced CRC patients who harbor the BRAF V600E mutation have a poorer prognosis, they are eligible for combinatorial therapy targeting EGFR/BRAF or BRAF/MEK within the MAP kinase signaling pathway. Once primarily thought to be a negative prognostic marker, BRAF V600E mutation is now considered as a positive predictive factor with an opportunity for clinical intervention. A growing body of evidence also supports MSI testing as clinical benefits with immune checkpoint blockade by cancer immunotherapy have been demonstrated in MSI-high patients whose tumors exhibit high mutational burden. It has been established that UGT1A1*28 polymorphism is associated with irinotecan toxicity, but this test is rarely performed as the management strategy has not been identified. No established predictive biomarker for anti-VEGF therapy has yet to be discovered.It is becoming increasingly apparent that our growing understanding of biomarkers is revolutionizing and improving our strategies in the treatment of advanced CRC. Traditional nonselective cytotoxic chemotherapy is gradually being augmented and even in some cases supplanted by selective targeted agents based on our increasing understanding of tumor signaling and mechanism at the molecular level. The prospect of personalized medicine in directing treatment approaches that are optimally beneficial for patients brings tremendous excitement to the growing field of cancer therapeutics. As discussed in this chapter, the concurrent development of molecular biomarkers with new treatment strategies holds great promise of precision medicine in improving outcomes for patients with advanced CRC. PMID- 29589316 TI - Testing Cell-Based Immunotherapy for Colorectal Cancer. AB - Cell-based immunotherapy for cancer is emerging as an attractive alternative to conventional small-molecule or antibody-based treatment. Due to the characteristics of cell-based therapy, validation of test materials before in vivo administration is required. Here we describe general validation steps for preclinical evaluation of cell-based immunotherapy. We also describe a xenograft model of human colorectal cancer. This model can be used for applied to preclinical evaluation of various cell-based therapy regimens for colorectal cancer treatment. PMID- 29589317 TI - Patient-Derived Xenograft Models of Colorectal Cancer: Procedures for Engraftment and Propagation. AB - Preclinical compounds tested in animal models often demonstrate limited efficacy when transitioned into patients. As a result, individuals are assigned to treatment regimens that may be ineffective at treating their disease. The development of more clinically relevant models, such as patient-derived xenografts (PDXs), will (1) more completely mimic the human condition and (2) more accurately predict tumor responses to previously untested therapeutics.PDX models are clinically relevant as tumor tissue is implanted directly from human donor to the mouse recipient. Therefore, these models prevent cell population selection, intentional or unintentional, as the human tissue adapts to an in vitro, two-dimensional environment prior to implantation into a three-dimensional in vivo murine host. Often, cell heterogeneity and tumor architecture can be maintained from human to the PDX model in the mouse. This protocol describes the engraftment and propagation processes for establishing colorectal (CRC) PDX models in mice, using tumor tissue from human subjects. PMID- 29589318 TI - Use of Organoids to Characterize Signaling Pathways in Cancer Initiation. AB - The development of intestinal organoid technology has greatly accelerated research in the field of colorectal cancer. Contrary to traditional cancer cell lines, organoids are composed of multiple cell types arranged in 3D structures highly reminiscent of their native tissues. Thus, organoids provide a near physiological and readily accessible model to study tissue morphogenesis, adult stem cell behavior and tumorigenesis. Here, we provide protocols for establishing intestinal organoid cultures from genetically modified mouse lines and describe methods to overexpress and knockout genes of interest using lentiviral-based approaches. PMID- 29589319 TI - Identification of Novel Molecules Targeting Cancer Stem Cells. AB - Multiple studies focused on tumor heterogeneity and cellular hierarchies have demonstrated the role of cancer stem cells (CSC) in tumor initiation and recurrence. Colorectal cancer is one of the leading causes of cancer-related death and is hierarchically organized, with the majority of tumor cells descending from a small population of colon cancer stem cells (CCSCs). Such a rare self-renewing population is marked by the acquisition of distinct chromatin regulation and transcriptional programs. Fundamental molecular deviations between CCSCs and bulk tumor cells as well as normal tissues represent a unique therapeutic access to develop novel, selective anticancer therapies.In this chapter, we describe a methodological pipeline to identify novel molecules to selectively target human CCSC. We present a point-by-point description of a typical phenotypic molecular screening experiment, aiming to identify selective modulators of human CCSCs vs. normal intestinal progenitor cells. PMID- 29589320 TI - Growing Wealth Gaps in Education. AB - Prior research on trends in educational inequality has focused chiefly on changing gaps in educational attainment by family income or parental occupation. In contrast, this contribution provides the first assessment of trends in educational attainment by family wealth and suggests that we should be at least as concerned about growing wealth gaps in education. Despite overall growth in educational attainment and some signs of decreasing wealth gaps in high school attainment and college access, I find a large and rapidly increasing wealth gap in college attainment between cohorts born in the 1970s and 1980s, respectively. This growing wealth gap in higher educational attainment co-occurred with a rise in inequality in children's wealth backgrounds, although the analyses also suggest that the latter does not fully account for the former. Nevertheless, the results reported here raise concerns about the distribution of educational opportunity among today's children who grow up in a context of particularly extreme wealth inequality. PMID- 29589321 TI - A History and Overview of the Behavioral Neuroscience of Learning and Memory. AB - Here, I provide a basic history of important milestones in the development of theories for how the brain accomplishes the phenomenon of learning and memory. Included are the ideas of Plato, Rene Descartes, Theodule Ribot, William James, Ivan Pavlov, John Watson, Karl Lashley, and others. The modern era of learning and memory research begins with the description of H.M. by Brenda Milner and the gradual discovery that the brain contains multiple learning and memory systems that are supported by anatomically discrete brain structures. Finally, a brief overview is provided for the chapters that are included in current topics in Behavioral Neuroscience-Learning and Memory. PMID- 29589322 TI - Current Topics Regarding the Function of the Medial Temporal Lobe Memory System. AB - The first clear insight that the medial temporal lobe of the human brain was in fact a system of anatomically connected structures that were organized into a memory system came in 1957 from the observations by Brenda Milner of the noted amnesic patient H.M. Subsequent work in humans, monkeys, and rodents has identified all of the components of the medial temporal lobe (MTL) that formed the memory system. Currently, work is ongoing to identify the specific contributions each structure in the medial temporal lobe makes towards the formation and storage of long-term declarative memory. The historical background of this work is described including what insights the study of noted neurologic patients H.M. and E.P. provided for understanding the function of the medial temporal lobe. The development of an animal model of medial temporal lobe function is described. Additionally, the insights that lead to the understanding that the brain contains multiple, anatomically discrete, memory systems are described. Finally, three current topics of debate are addressed: First, does the perirhinal cortex exclusively support memory, or does it support both memory and higher order visual perception? Second, is there an anatomical separation between recollection and familiarity? Third, is the organization of spatial memory different between humans and rats, or perhaps the difference is between the working memory capacities of the two species? PMID- 29589323 TI - Whole-tissue 3D imaging reveals intra-adipose sympathetic plasticity regulated by NGF-TrkA signal in cold-induced beiging. AB - Sympathetic arborizations act as the essential efferent signals in regulating the metabolism of peripheral organs including white adipose tissues (WAT). However, whether these local neural structures would be of plastic nature, and how such plasticity might participate in specific metabolic events of WAT, remains largely uncharacterized. In this study, we exploit the new volume fluorescence-imaging technique to observe the significant, and also reversible, plasticity of intra adipose sympathetic arborizations in mouse inguinal WAT in response to cold challenge. We demonstrate that this sympathetic plasticity depends on the cold elicited signal of nerve growth factor (NGF) and TrkA receptor. Blockage of NGF or TrkA signaling suppresses intra-adipose sympathetic plasticity, and moreover, the cold-induced beiging process of WAT. Furthermore, we show that NGF expression in WAT depends on the catecholamine signal in cold challenge. We therefore reveal the key physiological relevance, together with the regulatory mechanism, of intra adipose sympathetic plasticity in the WAT metabolism.

PMID- 29589326 TI - Robust multi-label transfer feature learning for early diagnosis of Alzheimer's disease. AB - Transfer learning has been successfully used in the early diagnosis of Alzheimer's disease (AD). In these methods, data from one single or multiple related source domain(s) are employed to aid the learning task in the target domain. However, most of the existing methods utilize data from all source domains, ignoring the fact that unrelated source domains may degrade the learning performance. Also, previous studies assume that class labels for all subjects are reliable, without considering the ambiguity of class labels caused by slight differences between early AD patients and normal control subjects. To address these issues, we propose to transform the original binary class label of a particular subject into a multi-bit label coding vector with the aid of multiple source domains. We further develop a robust multi-label transfer feature learning (rMLTFL) model to simultaneously capture a common set of features from different domains (including the target domain and all source domains) and to identify the unrelated source domains. We evaluate our method on 406 subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database with baseline magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) data. The experimental results show that the proposed rMLTFL method can effectively improve the performance of AD diagnosis, compared with several state-of-the-art methods. PMID- 29589327 TI - Response to "Letter to the Editor" by R. Dhar. PMID- 29589329 TI - Tactical Neurocritical Care. AB - Neurocritical care is usually practiced in the comfort of an intensive care unit within a tertiary care medical center. Physicians deployed to the frontline with the US military or allied military are required to use their critical care skills and their neurocritical skills in austere environments with limited resources. Due to these factors, tactical critical care and tactical neurocritical care differ significantly from traditional critical care. Operational constraints, the tactical environment, and resource availability dictate that tactical neurocritical care be practiced within a well-defined, mission-constrained framework. Although limited interventions can be performed in austere conditions, they can significantly impact patient outcome. This review focuses on the US Army approach to the patient requiring tactical neurocritical care specifically point of injury care and care during transportation to a higher level of care. PMID- 29589328 TI - Influence of Bleeding Pattern on Ischemic Lesions After Spontaneous Hypertensive Intracerebral Hemorrhage with Intraventricular Hemorrhage. AB - BACKGROUND: Concomitant acute ischemic lesions are detected in up to a quarter of patients with spontaneous intracerebral hemorrhage (ICH). Influence of bleeding pattern and intraventricular hemorrhage (IVH) on risk of ischemic lesions has not been investigated. METHODS: Retrospective study of all 500 patients enrolled in the CLEAR III randomized controlled trial of thrombolytic removal of obstructive IVH using external ventricular drainage. The primary outcome measure was radiologically confirmed ischemic lesions, as reported by the Safety Event Committee and confirmed by two neurologists. We assessed predictors of ischemic lesions including analysis of bleeding patterns (ICH, IVH and subarachnoid hemorrhage) on computed tomography scans (CT). Secondary outcomes were blinded assessment of mortality and modified Rankin scale (mRS) at 30 and 180 days. RESULTS: Ischemic lesions occurred in 23 (4.6%) during first 30 days after ICH. Independent risk factors associated with ischemic lesions in logistic regression models adjusted for confounders were higher IVH volume (p = 0.004) and persistent subarachnoid hemorrhage on CT scan (p = 0.03). Patients with initial IVH volume >= 15 ml had five times the odds of concomitant ischemic lesions compared to IVH volume < 15 ml. Patients with ischemic lesions had significantly higher odds of death at 1 and 6 months (but not poor outcome; mRS 4-6) compared to patients without concurrent ischemic lesions. CONCLUSIONS: Occurrence of ischemic lesions in the acute phase of IVH is not uncommon and is significantly associated with increased early and late mortality. Extra-parenchymal blood (larger IVH and visible subarachnoid hemorrhage) is a strong predictor for development of concomitant ischemic lesions after ICH. PMID- 29589330 TI - The Use of Continuous EEG Monitoring in Intensive Care Units in The Netherlands: A National Survey. AB - BACKGROUND: Currently, continuous electroencephalographic monitoring (cEEG) is the only available diagnostic tool for continuous monitoring of brain function in intensive care unit (ICU) patients. Yet, the exact relevance of routinely applied ICU cEEG remains unclear, and information on the implementation of cEEG, especially in Europe, is scarce. This study explores current practices of cEEG in adult Dutch ICU departments focusing on organizational and operational factors, development over time and factors perceived relevant for abstaining its use. METHODS: A national survey on cEEG in adults among the neurology and adult intensive care departments of all Dutch hospitals (n = 82) was performed. RESULTS: The overall institutional response rate was 78%. ICU cEEG is increasingly used in the Netherlands (in 37% of all hospitals in 2016 versus in 21% in 2008). Currently in 88% of university, 55% of teaching and 14% of general hospitals use ICU cEEG. Reasons for not performing cEEG are diverse, including perceived non-feasibility and lack of data on the effect of cEEG use on patient outcome. Mostly, ICU cEEG is used for non-convulsive seizures or status epilepticus and prognostication. However, cEEG is never or rarely used for monitoring cerebral ischemia and raised intracranial pressure in traumatic brain injury. Review and reporting practices differ considerably between hospitals. Nearly all hospitals perform non-continuous review of cEEG traces. Methods for moving toward continuous review of cEEG traces are available but infrequently used in practice. CONCLUSIONS: cEEG is increasingly used in Dutch ICUs. However, cEEG practices vastly differ between hospitals. Future research should focus on uniform cEEG practices including unambiguous EEG interpretation to facilitate collaborative research on cEEG, aiming to provide improved standard patient care and robust data on the impact of cEEG use on patient outcome. PMID- 29589332 TI - The Mechanical Characterisation of Bovine Embolus Analogues Under Various Loading Conditions. AB - Embolus Analogues (EAs) can provide understanding of the mechanical characteristics of blood clots of cardiac origin. Bovine EAs (n = 29) were fabricated with varying concentrations of thrombin (0-20 NIHU/ml blood). Histological staining confirmed that EA composition compared sufficiently with human samples reported in literature. EAs were mechanically described under seven testing conditions: tensile, compression, shear wave ultrasound elastography (SWE), parallel plate rheometry, indentation, creep and relaxation. The Young modulus of bovine EAs in tension varied from 7 kPa (5% strain) to 84 kPa (50% strain). The compressive Young modulus increased with increasing thrombin concentration, which was in agreement with the SWE results. There was no significant difference in Young modulus throughout the clot (p < 0.05). The EAs displayed a non-linear response under parallel plate rheometry, creep and stress relaxation. The 3rd order Mooney-Rivlin constitutive equation and Standard Linear Solid model were used to fit the non-linear stress-strain response and time dependent properties, respectively. This is the first study in which bovine EAs, with and without addition of thrombin, are histologically and mechanically described with corresponding proposed constitutive equations. The equations and experimental data determined can be applied for future numerical and experimental testing of mammalian EAs and cardiac source clots. PMID- 29589331 TI - Population Pharmacokinetic Analysis of Asunaprevir in Subjects with Hepatitis C Virus Infection. AB - INTRODUCTION: Asunaprevir (ASV) is a potent, pangenotypic, twice-daily hepatitis C virus (HCV) NS3 inhibitor indicated for the treatment of chronic HCV infection. METHODS: A population pharmacokinetic (PPK) model was developed using pooled ASV concentration data from 1239 HCV-infected subjects who received ASV either as part of the DUAL regimen with daclatasvir or as part of the QUAD regimen with daclatasvir and peg-interferon/ribavirin. RESULTS: A two-compartment model with first-order elimination from the central compartment, an induction effect on clearance, and an absorption model consisted of zero-order release followed by first-order absorption adequately described ASV PK after oral administration. A typical value for ASV clearance (CL/F) was 50.8 L/h, increasing by 43% after 2 days to a CL/F of 72.5 L/h at steady-state, likely due to auto-induction of cytochrome P450 3A4 (CYP3A4). Factors indicative of hepatic function were identified as key influential covariates on ASV exposures. Subjects with cirrhosis had an 84% increase in ASV area under the concentration time curve (AUC) and subjects with baseline aspartate aminotransferase (AST) above 78 IU/L had a 58% increase in area under the concentration time curve (AUC). Asians subjects had a 46% higher steady-state AUC relative to White/Caucasian subjects. Other significant covariates were formulation, age, and gender. CONCLUSION: The current PPK model provided a parsimonious description of ASV concentration data in HCV-infected subjects. Key covariates identified in the model help explain the observed variability in ASV exposures and may guide clinical use of the drug. FUNDING: Bristol-Myers Squibb. PMID- 29589333 TI - Effect of response format on cognitive reflection: Validating a two- and four option multiple choice question version of the Cognitive Reflection Test. AB - The Cognitive Reflection Test, measuring intuition inhibition and cognitive reflection, has become extremely popular because it reliably predicts reasoning performance, decision-making, and beliefs. Across studies, the response format of CRT items sometimes differs, based on the assumed construct equivalence of tests with open-ended versus multiple-choice items (the equivalence hypothesis). Evidence and theoretical reasons, however, suggest that the cognitive processes measured by these response formats and their associated performances might differ (the nonequivalence hypothesis). We tested the two hypotheses experimentally by assessing the performance in tests with different response formats and by comparing their predictive and construct validity. In a between-subjects experiment (n = 452), participants answered stem-equivalent CRT items in an open ended, a two-option, or a four-option response format and then completed tasks on belief bias, denominator neglect, and paranormal beliefs (benchmark indicators of predictive validity), as well as on actively open-minded thinking and numeracy (benchmark indicators of construct validity). We found no significant differences between the three response formats in the numbers of correct responses, the numbers of intuitive responses (with the exception of the two-option version, which had a higher number than the other tests), and the correlational patterns of the indicators of predictive and construct validity. All three test versions were similarly reliable, but the multiple-choice formats were completed more quickly. We speculate that the specific nature of the CRT items helps build construct equivalence among the different response formats. We recommend using the validated multiple-choice version of the CRT presented here, particularly the four-option CRT, for practical and methodological reasons.

PMID- 29589336 TI - Acute hospital reconfiguration and self-harm presentations: a before-and-after study. AB - BACKGROUND: The evidence for improved patient outcomes following acute hospital reconfiguration is limited. AIMS: We assessed the impact of the reconfiguration of acute services within a hospital group in terms of the number and clinical management of self-harm presentations. METHODS: The study was conducted across the three Mid-Western regional hospitals in Ireland during 2004-2014. Reconfiguration in April 2009 involved two hospitals reducing the operation of their emergency departments (EDs) from 24 to 12 h. We used Poisson regression analysis of data from the National Self-Harm Registry Ireland to assess change in the hospital burden and clinical management of self-harm associated with the reconfiguration. RESULTS: We observed that the cumulative decrease in self-harm presentations at the two reconfigured hospitals was of a similar magnitude to the increase observed at the larger hospital. Despite this large increase in presentations, there was only a small increase in admissions. Reconfiguration of hospital services was also associated with changes in the provision of assessments for self-harm patients. CONCLUSIONS: There is evidence to suggest that acute hospital reconfiguration of hospital services impacts on patterns of patient flow. Findings have implications for those implementing reconfiguration of acute services. PMID- 29589334 TI - Toward Escherichia coli bacteria machine for water oxidation. AB - Nature uses a Mn oxide-based catalyst for water oxidation in plants, algae, and cyanobacteria. Mn oxides are among major candidates to be used as water-oxidizing catalysts. Herein, we used two straightforward and promising methods to form Escherichia coli bacteria/Mn oxide compounds. In one of the methods, the bacteria template was intact after the reaction. The catalysts were characterized by X-ray photoelectron spectroscopy, visible spectroscopy, scanning electron microscopy, high-resolution transmission electron microscopy, diffuse reflectance infrared Fourier transform spectroscopy, Raman spectroscopy, and X-ray diffraction spectrometry. Electrochemical properties of the catalysts were studied, and attributed redox potentials were assigned. The water oxidation of the compounds was examined under electrochemical condition. Linear sweep voltammetry showed that the onsets of water oxidation in our experimental condition for bacteria and Escherichia coli bacteria/Mn oxide were 1.68 and 1.56 V versus the normal hydrogen electrode (NHE), respectively. Thus, the presence of Mn oxide in the catalyst significantly decreased (~ 120 mV) the overpotential needed for water oxidation. PMID- 29589337 TI - Future career intentions of higher specialist trainees in general Paediatrics. AB - BACKGROUND: A survey of paediatric higher specialist trainees was carried out in 2002 assessing career intentions and perception of training. Fourteen years later, with increased numbers of trainees and a national model of care and a tertiary paediatric hospital on the horizon, we re-evaluated the career intentions of the current trainee workforce. AIMS: To assess the career intentions of the current paediatric higher specialist trainees. METHODS: A 28 item questionnaire was developed based on a previously validated instrument and distributed online using the Royal College of Physicians of Ireland trainee database. RESULTS: We distributed the questionnaire to 118 eligible trainees and received responses from 92 (78%). Seventy-nine (86%) respondents desire a consultant post in Ireland. Seventy-five (82%) indicated that their preferred consultant post location was in a tertiary paediatric centre. Sixty-two trainees (67%) intend to become subspecialists with 25 (27%) planning a career in general paediatrics. This contrasts with the 2002 survey when 76% wished to work in urban centres and 61% of trainees planned a career in general paediatrics. CONCLUSION: There appears to be a mismatch between the career goals of the future paediatric consultant workforce and the requirements for staffing paediatric units nationally. This has the potential to complicate the proposed expansion of general paediatricians in regional centres and result in a significant proportion of current trainees failing to secure a post in their desired location. PMID- 29589338 TI - Cardiovascular disease risk factor profile of male Gaelic Athletic Association sports referees. AB - BACKGROUND: Cardiovascular disease (CVD) is the primary cause of morbidity and mortality in Ireland and worldwide. Male sporting referees registered with the Gaelic Athletic Association (G.A.A.) represent the Irish male population due to the wide range of ages and CVD risk factors. Although G.A.A. referees, a predominately male population, play a pivotal part in the success of the game, there is a paucity of epidemiological evidence relating to their CVD health status. AIMS: The purpose of this study was to assess the CVD risk factor profile of male G.A.A. referees in Ireland. METHODS: An observational, cross-sectional study design was used to assess the CVD risk factor profile of the participants. A cluster and convenience sample method was used to recruit participants aged >= 18 years within the G.A.A. referee community throughout Ireland. CVD risk factor profiles were studied using questionnaires, blood pressure (BP) and anthropometric measurements. RESULTS: A total of 183 male G.A.A. referees were studied with a mean age of 39 years (+/- 6, p = 0.000) for inter-county and 47 (+/- 11) for club referees. Of the total population studied, 49% had pre hypertension and 60% were overweight. CONCLUSIONS: The findings from this study demonstrate the presence of hypertension and negative lifestyle behaviours within this male population. This justifies the need to implement a policy on the pre participation screening and risk reduction of CVD for male G.A.A. referees in Ireland. This health promotion intervention would assist in reducing the CVD epidemic within this specific population.

PMID- 29589340 TI - Influence of Nutritional Status on the Absorption of Polyphyllin I, an Anticancer Candidate from Paris polyphylla in Rats. AB - BACKGROUND AND OBJECTIVES: Protein-calorie malnutrition (PCM) is one of the most suffered complications in cancer patients. Polyphyllin I (PPI), a saponin isolated from rhizome of Paris polyphylla, is a potential candidate in cancer therapy. In this study, the influence of nutritional status on the absorption of PPI in rats was explored after oral administration. METHODS: PCM rats, namely mal nourished (MN) rats, were induced from well-nourished (WN) rats by caloric restriction protocol. Intestinal absorption of PPI in WN and MN rats was evaluated by pharmacokinetic and intestinal perfusion methods. The potential mechanisms between two groups were investigated on the basis of intestinal permeability, intestinal efflux and PPI's depletions in vivo. The intestinal permeability was analyzed by determining the concentration of paracellular marker transport in serum and the expression of junction proteins in intestine. The intestinal efflux was evaluated through comparing the protein level of P glycoprotein (P-gp) in intestine, and the depletions of PPI and/or generation of its metabolites in liver and intestines were analyzed by liquid chromatography triple quadrupole mass spectrometry (LC-MS/MS) method. RESULTS: Compared to WN rats, the oral systemic exposure of PPI was significantly increased in MN rats, evidenced by significant enhancement of maximum plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC0-60h) by more than 2.51- and 3.71-folds as well as terminal elimination half-life (t1/2) prolonged from to 7.3 to 14.1 h. Further studies revealed that the potential mechanism might be associated with combined contribution of improved intestinal absorption and depressed deglycosylation of PPI in MN rats. Furthermore, enhanced intestinal absorption of PPI was benefited from increased intestinal permeability and decreased intestinal efflux in MN rats. Meanwhile, the former manifested as increased transport of paracellular marker and decreased junction proteins levels, while the later evidenced by reduced P-gp expression. CONCLUSIONS: The oral exposure of PPI was enhanced in MN rats, which suggested that nutritional status alters the absorption of PPI, and thus the dosage of PPI should be modified during the treatment of cancer patient with PCM.

AB - To enhance the bioavailability of testosterone undecanoate (TU) and overcome the current problem of soft capsules (Andriol Testocaps(r)), Nano-structured lipid carriers (NLC) for TU was developed. First, suspension of TU-loaded NLC (TU-NLC) was prepared by high pressure homogenization; then adsorbent or a protective agent beta-cyclodextrin was used to solidify the suspension through a vacuum system; finally, the solid powder of TU-loaded NLC (solid TU-NLC) was filled into hard capsules. The characteristics of solid TU-NLC, were investigated in vitro and vivo. The particle size of TU-NLC was about 273.3 nm, the potential was 0.156+/-0.04. Transmission electron microscope (TEM) revealed that the NLC was spherical and uniform. Differential scanning calorimetry (DSC) suggested the drug had been encapsulated into NLC lipid matrix. The drug release proved that solid TU-NLC showed a higher dissolution in vitro. The CaCO-2 cell permeability showed that solid TU-NLC could enhance trans-membrane absorption of the TU. Moreover, the AUC of solid TU-NLC formulations (4304+/-550.50 MUg/L*min) was higher than commercial product Andriol Testocaps(r) (3075+/-372.50 MUg/L*min). In conclusion, solid TU-NLC could enhance the rate of dissolution, and had a relatively higher bioavailability than Andriol Testocaps(r) in vivo GRAPHICAL ABSTRACT: . PMID- 29589343 TI - Anticoagulation therapy in haemophilia. AB - Patients with haemophilia (PWH) are relatively protected from cardiovascular death. Recent insights have shown that this is not due to less formation of atherosclerosis than in non-haemophilic men, therefore protection from the final occlusive thrombus will be the major determinant. Prevalence and incidence rates of cardiovascular disease (especially non-fatal events) are scarce, although ongoing studies are addressing this issue.Meanwhile, because the haemophilia population is aging, we are increasingly confronted with cardiovascular events. The main cardio vascular risk factors that should be part of regular screening programs are hypertension, overweight, lipometabolic disorders and smoking. Anticoagulation therapy in haemophilia is feasible, provided that individual tailored coagulation therapy and close monitoring is provided.Here, we present our view on anticoagulation management in PWH. There is an absolute need for risk assessment tools and prospective validation of suggested anticoagulation management strategies in PWH. Until then, we are managing the unknown.

AB - Immunocompromised children and adolescents receiving treatment for cancer have a considerably increased risk for infection. Neutropenia is the most important single risk factor for infectious complications, and fever in neutropenia is considered as an emergency. Whereas guidelines for the management of fever in neutropenic adults have been established for decades, specific pediatric guidelines have not been developed until recently. As children differ in many aspects from adults such as in the underlying malignancy or in the availability and dosing of antimicrobial compounds, guidelines for pediatric patients are important. This article reviews similarities and differences between the recently published German interdisciplinary guideline of the German Societies of Pediatric Infectious Diseases and Pediatric Oncology and Hematology and a guideline developed by a panel of international experts for the management of fever in neutropenia in children and adolescents. PMID- 29589349 TI - The vulnerable myocardium. AB - Cardiovascular disease is the major cause of morbidity and mortality in subjects suffering from diabetes mellitus. While coronary artery disease is the leading cause of cardiac complications in diabetics, it is widely recognized that diabetes increases the risk for the development of heart failure independently of coronary heart disease and hypertension. This increased susceptibility of the diabetic heart to develop structural and functional impairment is termed diabetic cardiomyopathy. The number of different mechanisms proposed to contribute to diabetic cardiomyopathy is steadily increasing and underlines the complexity of this cardiac entity.In this review the mechanisms that account for the increased myocardial vulnerability in diabetic cardiomyopathy are discussed. PMID- 29589350 TI - The vulnerable blood. AB - Patients with diabetes are at increased risk of cardiovascular morbidity and mortality. While arteriosclerotic lesions have long been recognized as the underlying cause more recent studies suggest that alterations of the blood are also critically involved. Following plaque rupture, adherence of platelets is followed by the formation of a cross-linked fibrin clot. Patients with diabetes exhibit a prothrombotic milieu consisting of hyper reactive platelets, a tight and rigid clot structure which is due to up-regulation of coagulation factors and prolongation of clot lysis. Metabolic alterations as well as inflammatory processes, which are up-regulated in diabetes, are thought to be the main underlying causes. More recently, the complement cascade has emerged as a potential new player in this context with several complement components directly influencing both platelet function and coagulation.This review provides an overview concerning the changes that lead to alterations of platelet function and clot structure in diabetes. PMID- 29589351 TI - Genetics in thrombophilia. AB - Venous thromboembolism (VTE) poses a worldwide health burden affecting millions of people each year. The annual incidence of symptomatic VTE, the collective term used here for deep venous thrombosis, pulmonary embolism or both, is 2-3 per thousand inhabitants. The one-year mortality is 20% after a first VTE. Of the surviving patients 15-25% will experience a recurrent episode of VTE in the three years after the first event. Primary and secondary prevention is key to reducing death and disability from VTE. How to make use of our current knowledge of inherited risk of VTE for primary and secondary disease prevention is not straightforward. This despite the fact that in the past two or three decades we have made major strides in enlarging our understanding of inherited VTE risk, and that new inherited risk factors continue to be identified.For primary prevention of VTE genetic testing is not likely to play a role in the future. Genetic variations also determine recurrence risk, albeit that the effect sizes for individual genetic variations are invariably lower than those for first VTE events. Multilocus genetic risk scores improve risk classification, and it is now possible to stratify patients who have had a first venous thrombosis, into subgroups with a high and low risk of recurrence. Whether this approach can be used to tailor intensity and duration of treatment remains to be established. PMID- 29589352 TI - Kidney and haemostasis. AB - : Renal insufficiency is characterized by thrombocytopathy, caused by the accumulation of water soluble and protein bound waste products of protein metabolism, which are not adequately eliminated by the kidney. The kidneys also excrete drugs and their metabolites, which accumulate if dosages are not adjusted to the renal function and may cause clinically relevant bleeding (i. e. synthetic penicillins, vitamin K antagonists, new oral anticoagulants). Therefore, each patients kidney function (GFR) ought to be evaluated by the KDIGO guidelines. The survival of chronic renal patients is lowered by increasing cardiovascular complications. Particularly frequent is non-valvular atrial fibrillation. The recommended prophylaxis with vitamin K antagonists for renal insufficiency is hampered by increased bleeding as well as by augmented (coronary) vascular and valvular calcification. It is not known yet whether prophylaxis with vitamin K may prevent this complication. CONCLUSION: Because new oral anticoagulants are equally or even more effective and cause less bleeding, they may be favoured in future and even in end-stage renal failure if more is known about dosing, safety and efficacy. The measurement of serum FGF 23 concentration may be helpful as a marker for their use. PMID- 29589353 TI - Anticoagulation in patients with impaired renal function and with haemodialysis. AB - Patients with impaired renal function are exposed to an increased risk for bleeding complications depending on the amount of the anticoagulant eliminated by the kidneys. The elimination of unfractionated heparins, vitamin K antagonists and argatroban is only minimally influenced by a reduced renal function. Low molecular weight heparins, fondaparinux, danaparoid, hirudins and nonvitamin K antagonist oral anticoagulants (NOAC) cause a variably increased bleeding risk in renal impairment. Dose reductions are recommended for all of these anticoagulants in renal impairment, some are even contraindicated at certain levels of renal impairment. Their benefit over the conventional anticoagulants is preserved if renal dosing is employed. For end-stage renal disease patients specific treatment regimens are required. PMID- 29589354 TI - ?

AB - Protein Z (PZ) is a vitamin K-dependent factor identified in human plasma in 1984 but it has no enzymatic activity. It is a cofactor of a serpin, the protein Z dependent protease inhibitor (ZPI), and the complex PZ/ZPI inhibits activated factor X on phospholipid surfaces. In mice, the disruption of PZ or ZPI gene is asymptomatic, but enhances the thrombotic phenotype and mortality of other thrombotic risk factors. Most of the clinical studies focused on PZ. Despite conflicting results, a recent meta-analysis indicated that PZ deficiency could be a risk for venous and arterial thrombosis and early fetal loss. However, these conclusions are drawn from case-control studies of small size, constituting an important limitation. Recently, it was shown that PZ and/or ZPI are synthesised by normal kidney and different cancer cells, suggesting that the complex PZ/ZPI could play a role in inhibiting the tissue deposition of fibrin. The physiopathological consequences of these observations remain to be established. At this time, the measurement of plasma PZ and ZPI or analysis of their gene polymorphisms should not be performed routinely for the exploration of thrombophilia. PMID- 29589359 TI - Impact-Faktor 2011 = 1,190. PMID- 29589358 TI - Factor VII activating protease. AB - Factor VII activating protease (FSAP) is a circulating serine protease with high homology to fibrinolytic enzymes. A role in the regulation of coagulation and fibrinolysis is suspected based on in vitro studies demonstrating activation of FVII or pro-urokinase plasminogen activator (uPA). However, considering the paucity of any studies in animal models or any correlative studies in humans the role of FSAP in haemostasis remains unclear. In relation to vascular remodeling processes or inflammation it has been convincingly shown that FSAP interacts with growth factors as well as protease activated receptors (PAR). Against this sparse background there are a plethora of studies which have investigated the linkage of single nucleotide polymorphisms (SNP) in the FSAP gene (HABP2) to various diseases. The G534E SNP of FSAP is associated with a low proteolytic activity due to an amino acid exchange in the protease domain. This and other SNPs have been linked to carotid stenosis, stroke as well as thrombosis in the elderly and plaque calcification. These SNP analyses indicate an important role for FSAP in the regulation of the haemostasis system as well as fibroproliferative inflammatory processes. PMID- 29589360 TI - ? PMID- 29589361 TI - Elinogrel, an orally and intravenously available ADP-receptor antagonist. AB - The antiplatelet therapy with aspirin and the ADP-receptor blocker clopidogrel is currently the standard medication after coronary intervention or after acute coronary syndrome to prevent recurrent ischemic events and reduce mortality. However, high interindividual response variability to antiplatelet treatment is described in up to 44% of treated patients. A poor response to clopidogrel is caused by multifactorial mechanisms. Individual risk assessment including platelet function testing (PFT) can help to identify high risk patients, although recent randomized trials to investigate effects of PFT-guided therapy have failed to detect an impact on prognostic outcome. Poor response to standard antiplatelet agents can be overcome by switching to alternate substances. Elinogrel is a novel competitive, reversible ADP-receptor antagonist available in oral and intravenous formulation. Additional treatment with elinogrel showed advantages over clopidogrel, including more rapid, less variable, and more complete inhibition of platelet function without significantly increased bleeding complications. This review gives an overview over the investigational drug elinogrel for use in a personalized antiplatelet approach. PMID- 29589362 TI - Oral anticoagulation with edoxaban. AB - Edoxaban (the former DU176b) an orally available direct factor Xa inhibitor has been engineered from DX-9065a, which was one of the first parenteral Xa inhibitors. Edoxaban has a time to peak plasma concentrations of 1-2 hours and a half-life of approximately 10 hours after multiple doses. Edoxaban is the third new oral anticoagulant in the group of direct factor Xa inhibitors that has gained clinical approval for the prevention of venous thromboembolism after major orthopaedic surgery. Currently, edoxaban is assessed in late stage clinical development for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (ENGAGE AF-TIMI 48, NCT00781391) and for the treatment and prevention of venous thromboembolism in patients with acute deep vein thrombosis and/or pulmonary embolism (HOKUSAI VTE, NCT00986154).Both clinical phase III trials represent the largest single clinical studies in their entity so far with an enrolment of 21 107 patients in ENGAGE AF-TIMI 48 and a planned enrolment of 7500 patients in HOKUSAI VTE.The pharmacological properties of edoxaban will be discussed along with the current late stage clinical development focusing on the prevention of stroke and venous thromboembolism. PMID- 29589363 TI - Vorapaxar expands antiplatelet options. AB - Vorapaxar is the first substance of a new class of antiplatelet drugs that has been tested in large clinical trials. The protease-activated receptor 1 (PAR-1) antagonist inhibits thrombin-induced platelet activation to prevent atherothrombosis. In the phase 3 trials TRACER (acute coronary syndrome) and TRA 2P-TIMI 50 (stable atherosclerosis) reducing ischemic events with vorapaxar came at the cost of bleeding.TRACER compared vorapaxar to placebo in 12 944 patients who had non-ST-segment elevation acute coronary syndromes on top of contemporary treatment including dual antiplatelet therapy (aspirin and clopidogrel). Vorapaxar reduced ischemic events non-significantly, but increased bleeding significantly, therefore not justifying triple antiplatelet therapy in this setting. Follow-up was stopped early because of bleeding. TRA 2P-TIMI 50 examined 26 449 patients who had a history of myocardial infarction, ischemic stroke, or peripheral arterial disease. Vorapaxar reduced ischemic events and increased bleeding both significantly. Recruitment of patients with prior stroke was stopped early. Net clinical outcome and subgroup analyses suggested that vorapaxar could be beneficial for patients with prior myocardial infarction - but no history of stroke. PMID- 29589364 TI - Atopaxar. AB - Atopaxar, also known as E 5555 is a novel reversible protease-activated receptor 1 (PAR-1) thrombin receptor antagonist. To date, Atopaxar has been investigated in phase II trials with focus on safety and tolerability in patients with acute coronary syndromes or stable coronary artery disease on top of standard antiplatelet therapy. Atopaxar was generally well tolerated, however a rise in liver enzymes and prolongation of the QTcF interval were observed. The data suggest, that atopaxar administration may promote some minor bleeding complications, but does not seem to significantly increase the risk of major bleeding. Although not powered for efficacy, the currently available data suggest potential benefits in patients at high risk for recurrent ischemic events on top of standard antiplatelet therapy. In conclusion, more studies (e.g. phase III) are needed to evaluate efficacy and safety of atopaxar. PMID- 29589370 TI - Percutaneous mitral balloon valvuloplasty: beyond classic indications. AB - BACKGROUND AND AIM: In patients with mitral stenosis (MS) percutaneous mitral balloon valvuloplasty (PMBV) is used to im-prove symptoms and prognosis. Although there is some evidence for potential long-term benefits from PMBV in asymptomatic patients with mitral valve area (MVA) between 1.0 and 1.5 cm2, there are no follow-up data on patients with symptomatic MS with MVA > 1.5 cm2, who underwent PMBV. METHODS: We retrospectively analysed periprocedural results of 113 symptomatic patients who underwent PMBV for MS with MVA > 1.5 cm2 (group 1) and compared them with a control group of patients with MVA <= 1.5 cm2 (group 2). Clinical and procedural variables were compared between groups. RESULTS: In group 1, PMBV resulted in a significant increase of MVA as well as a decrease of mean and maximal mitral gradients and mean left atrial pressure (LAP), and a subsequent decrease of mean and systolic pulmonary artery pressures (PAPs). Moreover, 6.3% of patients developed moderate to severe (3+) or severe (4+) post procedural mitral regurgitation (MR). Post-procedural increase in MVA and decrease of LAP were more pronounced in group 2 than group 1 (?MVA 0.74 cm2 vs. 0.41 cm2, p < 0.05, and ?LAP 8.2 mmHg vs. 6.0 mmHg, p < 0.05). Nonetheless, no significant differences were observed for ? of mean and systolic PAPs. The grade of post-procedural MR was comparable between groups. CONCLUSIONS: PMBV is a feasible procedure in highly selected patients without classic echocardiographic indications. None-theless, it is associated with a small but non-negligible periprocedural risk of developing severe MR.

PMID- 29589379 TI - Results and factors associated with adverse outcome after tricuspid valve replacement. AB - BACKGROUND AND AIM: This retrospective analysis of patients with severe tricuspid valve disease, who underwent tricuspid valve replacement (TVR) for either tricuspid regurgitation or stenosis, has been designed to determine the factors that predict poor hospital and long-term survival. METHODS: The study population comprised 86 patients, 65 women and 21 men, who underwent TVR with or without con comitant surgical procedures between 2000 and 2010 at our institution. Patients with Ebstein's or other complex congenital anomalies were excluded from the study. RESULTS: Average age at operation was 58.5 +/- 12.5 (range 16-78) years. Fifty (58.1%) patients had undergone previous cardiac surgery. Forty-two patients were in New York Heart Association (NYHA) class III functional capacity, and 18 were in class IV. Symptoms of right heart failure (HF) were present in 66 patients, of whom 19 had ascites. Bioprosthetic tricuspid valves were implanted in 84 patients and mechanical prostheses in two. The choice to proceed to TVR instead of repair was individualised and based on the surgeon's preference. In hospital mortality was 18 (20.9%) patients, caused mainly by multi-organ and HF, and was significantly related to NYHA class and symptoms of right HF before surgery, with no mortality in patients with NYHA class I and II, 19% mortality with NYHA class III, and 55.6% mortality with NYHA class IV. Eighteen (20.9%) patients died during postoperative follow-up. The main risk factors associated with perioperative mortality were: the presence of severe symptoms at the time of surgery, low preoperative haematocrit, postoperative complications, postoperative ventilation time longer than 72 h, and renal failure requiring dialysis. Elevated pulmonary artery pressure, preoperative symptoms of right HF, and low haematocrit unfavourably affected the long-term results. CONCLUSIONS: Many earlier studies reported high mortality and morbidity after TVR in both early and late postoperative peri-ods. Our main finding is that good outcomes for TVR are achievable in properly selected patients. Sixty of 86 patients in our group had preoperative NYHA functional class III and IV, which suggests that surgical timing was late in many patients. Based on our observations, we propose that surgical correction of severe tricuspid valve disease should be considered before the development of advanced HF, when patients are asymptomatic or only oligosymptomatic. PMID- 29589380 TI - Massage, reflexology and other manual methods for pain management in labour. AB - BACKGROUND: Many women would like to avoid pharmacological or invasive methods of pain management in labour, and this may contribute towards the popularity of complementary methods of pain management. This review examined the evidence currently available on manual methods, including massage and reflexology, for pain management in labour. This review is an update of the review first published in 2012. OBJECTIVES: To assess the effect, safety and acceptability of massage, reflexology and other manual methods to manage pain in labour. SEARCH METHODS: For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register (30 June 2017), the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 6), MEDLINE (1966 to 30 June 2017, CINAHL (1980 to 30 June 2017), the Australian New Zealand Clinical Trials Registry (4 August 2017), Chinese Clinical Trial Registry (4 August 2017), ClinicalTrials.gov, (4 August 2017), the National Center for Complementary and Integrative Health (4 August 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (4 August 2017) and reference lists of retrieved trials. SELECTION CRITERIA: We included randomised controlled trials comparing manual methods with standard care, other non pharmacological forms of pain management in labour, no treatment or placebo. We searched for trials of the following modalities: massage, warm packs, thermal manual methods, reflexology, chiropractic, osteopathy, musculo-skeletal manipulation, deep tissue massage, neuro-muscular therapy, shiatsu, tuina, trigger point therapy, myotherapy and zero balancing. We excluded trials for pain management relating to hypnosis, aromatherapy, acupuncture and acupressure; these are included in other Cochrane reviews. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality, extracted data and checked data for accuracy. We contacted trial authors for additional information. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: We included a total of 14 trials; 10 of these (1055 women) contributed data to meta-analysis. Four trials, involving 274 women, met our inclusion criteria but did not contribute data to the review. Over half the trials had a low risk of bias for random sequence generation and attrition bias. The majority of trials had a high risk of performance bias and detection bias, and an unclear risk of reporting bias. We found no trials examining the effectiveness of reflexology.MassageWe found low-quality evidence that massage provided a greater reduction in pain intensity (measured using self-reported pain scales) than usual care during the first stage of labour (standardised mean difference (SMD) -0.81, 95% confidence interval (CI) -1.06 to -0.56, six trials, 362 women). Two trials reported on pain intensity during the second and third stages of labour, and there was evidence of a reduction in pain scores in favour of massage (SMD -0.98, 95% CI -2.23 to 0.26, 124 women; and SMD -1.03, 95% CI -2.17 to 0.11, 122 women). There was very low quality evidence showing no clear benefit of massage over usual care for the length of labour (in minutes) (mean difference (MD) 20.64, 95% CI -58.24 to 99.52, six trials, 514 women), and pharmacological pain relief (average risk ratio (RR) 0.81, 95% CI 0.37 to 1.74, four trials, 105 women). There was very low quality evidence showing no clear benefit of massage for assisted vaginal birth (average RR 0.71, 95% CI 0.44 to 1.13, four trials, 368 women) and caesarean section (RR 0.75, 95% CI 0.51 to 1.09, six trials, 514 women). One trial reported less anxiety during the first stage of labour for women receiving massage (MD 16.27, 95% CI -27.03 to -5.51, 60 women). One trial found an increased sense of control from massage (MD 14.05, 95% CI 3.77 to 24.33, 124 women, low-quality evidence). Two trials examining satisfaction with the childbirth experience reported data on different scales; both found more satisfaction with massage, although the evidence was low quality in one study and very low in the other.Warm packsWe found very low-quality evidence for reduced pain (Visual Analogue Scale/VAS) in the first stage of labour (SMD -0.59, 95% CI -1.18 to -0.00, three trials, 191 women), and the second stage of labour (SMD -1.49, 95% CI -2.85 to 0.13, two trials, 128 women). Very low-quality evidence showed reduced length of labour (minutes) in the warm-pack group (MD -66.15, 95% CI -91.83 to -40.47; two trials; 128 women).Thermal manual methodsOne trial evaluated thermal manual methods versus usual care and found very low-quality evidence of reduced pain intensity during the first phase of labour for women receiving thermal methods (MD -1.44, 95% CI -2.24 to -0.65, one trial, 96 women). There was a reduction in the length of labour (minutes) (MD -78.24, 95% CI -118.75 to -37.73, one trial, 96 women, very low-quality evidence). There was no clear difference for assisted vaginal birth (very low-quality evidence). Results were similar for cold packs versus usual care, and intermittent hot and cold packs versus usual care, for pain intensity, length of labour and assisted vaginal birth.Music One trial that compared manual methods with music found very low-quality evidence of reduced pain intensity during labour in the massage group (RR 0.40, 95% CI 0.18 to 0.89, 101 women). There was no evidence of benefit for reduced use of pharmacological pain relief (RR 0.41, 95% CI 0.16 to 1.08, very low-quality evidence).Of the seven outcomes we assessed using GRADE, only pain intensity was reported in all comparisons. Satisfaction with the childbirth experience, sense of control, and caesarean section were rarely reported in any of the comparisons. AUTHORS' CONCLUSIONS: Massage, warm pack and thermal manual methods may have a role in reducing pain, reducing length of labour and improving women's sense of control and emotional experience of labour, although the quality of evidence varies from low to very low and few trials reported on the key GRADE outcomes. Few trials reported on safety as an outcome. There is a need for further research to address these outcomes and to examine the effectiveness and efficacy of these manual methods for pain management. PMID- 29589381 TI - Continued Innovation in Respiratory Care: The Importance of Inhaler Devices. AB - When it comes to the use in inhalers in the management of chronic obstructive pulmonary diseases, there are many options, considerations and challenges, which health care professionals need to address. Considerations for prescribing and dispensing, administering and following up, education, and adherence; all of these factors impact on treatment success and all are intrinsically linked to the device selected. This review brings together relevant evidence, real-life data and practice tools to assist health care professionals in making decisions about the use of inhalers in the management of chronic obstructive pulmonary diseases. It covers some of the key technical device issues to be considered, the evidence behind the role of inhalers in disease control, population studies which link behaviors and adherence to inhaler devices as well as practice advice on inhaler technique education and the advantages and disadvantages in selecting different inhaler devices. Finally, a list of key considerations to aid health care providers in successfully managing the use of inhaler devices are summarized. PMID- 29589382 TI - The Phosphodiesterase 4 Inhibitor Roflumilast Protects against Cigarette Smoke Extract-Induced Mitophagy-Dependent Cell Death in Epithelial Cells. AB - BACKGROUND: Recent studies show that mitophagy, the autophagy-dependent turnover of mitochondria, mediates pulmonary epithelial cell death in response to cigarette smoke extract (CSE) exposure and contributes to the development of emphysema in vivo during chronic cigarette smoke (CS) exposure, although the underlying mechanisms remain unclear. METHODS: In this study, we investigated the role of mitophagy in the regulation of CSE-exposed lung bronchial epithelial cell (Beas-2B) death. We also investigated the role of a phosphodiesterase 4 inhibitor, roflumilast, in CSE-induced mitophagy-dependent cell death. RESULTS: Our results demonstrated that CSE induces mitophagy in Beas-2B cells through mitochondrial dysfunction and increased the expression levels of the mitophagy regulator protein, PTEN-induced putative kinase-1 (PINK1), and the mitochondrial fission protein, dynamin-1-like protein (DRP1). CSE-induced epithelial cell death was significantly increased in Beas-2B cells exposed to CSE but was decreased by small interfering RNA-dependent knockdown of DRP1. Treatment with roflumilast in Beas-2B cells inhibited CSE-induced mitochondrial dysfunction and mitophagy by inhibiting the expression of phospho-DRP1 and -PINK1. Roflumilast protected against cell death and increased cell viability, as determined by the lactate dehydrogenase release test and the MTT assay, respectively, in Beas-2B cells exposed to CSE. CONCLUSION: These findings suggest that roflumilast plays a protective role in CS-induced mitophagy-dependent cell death. PMID- 29589383 TI - Bone Health in Adrenal Disorders. AB - Secondary osteoporosis resulting from specific clinical disorders may be potentially reversible, and thus continuous efforts to find and adequately treat the secondary causes of skeletal fragility are critical to ameliorate fracture risk and to avoid unnecessary treatment with anti-osteoporotic drugs. Among the hyperfunctional adrenal masses, Cushing's syndrome, pheochromocytoma, and primary aldosteronism are receiving particularly great attention due to their high morbidity and mortality mainly by increasing cardiovascular risk. Interestingly, there is accumulating experimental and clinical evidence that adrenal hormones may have direct detrimental effects on bone metabolism as well. Thus, the present review discusses the possibility of adrenal disorders, especially focusing on pheochromocytoma and primary aldosteronism, as secondary causes of osteoporosis. PMID- 29589384 TI - Pathophysiology of Type 2 Diabetes in Koreans. AB - The pathophysiology of type 2 diabetes is characterized by variable degrees of insulin resistance and impaired insulin secretion. Both genetic and environmental factors serve as etiologic factors. Recent genetic studies have identified at least 83 variants associated with diabetes. A significant number of these loci are thought to be involved in insulin secretion, either through beta-cell development or beta-cell dysfunction. Environmental factors have changed rapidly during the past half century, and the increased prevalence of obesity and diabetes can be attributed to these changes. Environmental factors may affect epigenetic changes and alter susceptibility to diabetes. A recent epidemiologic study revealed that Korean patients with type 2 diabetes already had impaired insulin secretion and insulin resistance 10 years before the onset of diabetes. Those who developed diabetes showed impaired beta-cell compensation with an abrupt decrease in insulin secretion during the last 2 years before diabetes developed. The retrograde trajectory of the disposition index differed according to the baseline subgroups of insulin secretion and insulin sensitivity. We hope that obtaining a more detailed understanding of the perturbations in the major pathophysiologic process of diabetes on the individual level will eventually lead to the implementation of precision medicine and improved patient outcomes. PMID- 29589385 TI - Evolution of Diabetes Care in Hong Kong: From the Hong Kong Diabetes Register to JADE-PEARL Program to RAMP and PEP Program. AB - The rapid increase in diabetes prevalence globally has contributed to large increases in health care expenditure on diabetic complications, posing a major health burden to countries worldwide. Asians are commonly observed to have poorer beta-cell function and greater insulin resistance compared to the Caucasian population, which is attributed by their lower lean body mass and central obesity. This "double phenotype" as well as the rising prevalence of young onset diabetes in Asia has placed Asians with diabetes at high risk of cardiovascular and renal complications, with cancer emerging as an important cause of morbidity and mortality. The experience from Hong Kong had demonstrated that a multifaceted approach, involving team-based integrated care, information technological advances, and patient empowerment programs were able to reduce the incidence of diabetic complications, hospitalizations, and mortality. System change and public policies to enhance implementation of such programs may provide solutions to combat the burgeoning health problem of diabetes at a societal level.

PMID- 29589386 TI - Association of Adipokines with Development and Progression of Nonalcoholic Fatty Liver Disease. AB - Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease affecting 30% of the general population and 40% to 70% of obese individuals. Adipose tissue plays a crucial role in its pathogenesis, as it produces and secretes pro- and anti-inflammatory cytokines called adipokines. Adiponectin and leptin have well determined actions in terms of NAFLD pathophysiology. Adiponectin deficiency is associated with a pro-inflammatory condition, as it is observed in obesity and other metabolic disorders. On the other hand, increased leptin levels, above the normal levels, act as a pro-inflammatory stimulus. Regarding other adipokines (resistin, visfatin, chemerin, retinol-binding protein 4, irisin), data about their contribution to NAFLD pathogenesis and progression are inconclusive. In addition, pharmacological agents like thiazolidinediones (pioglitazone and rosiglitazone), that are used in the management of NAFLD exert favourable effects on adipokine levels, which in turn may contribute to the improvement of liver function. This review summarizes the current knowledge and developments in the association between adipokines and NAFLD and discusses possible therapeutic implications targeting the modulation of adipokine levels as a potential tool for the treatment of NAFLD. PMID- 29589387 TI - Evidence of the Possible Harm of Endocrine-Disrupting Chemicals in Humans: Ongoing Debates and Key Issues. AB - Evidence has emerged that endocrine-disrupting chemicals (EDCs) can produce adverse effects, even at low doses that are assumed safe. However, systemic reviews and meta-analyses focusing on human studies, especially of EDCs with short half-lives, have demonstrated inconsistent results. Epidemiological studies have insuperable methodological limitations, including the unpredictable net effects of mixtures, non-monotonic dose-response relationships, the non-existence of unexposed groups, and the low reliability of exposure assessment. Thus, despite increases in EDC-linked diseases, traditional epidemiological studies based on individual measurements of EDCs in bio-specimens may fail to provide consistent results. The exposome has been suggested as a promising approach to address the uncertainties surrounding human studies, but it is never free from these methodological issues. Although exposure to EDCs during critical developmental periods is a major concern, continuous exposure to EDCs during non critical periods is also harmful. Indeed, the evolutionary aspects of epigenetic programming triggered by EDCs during development should be considered because it is a key mechanism for developmental plasticity. Presently, living without EDCs is impossible due to their omnipresence. Importantly, there are lifestyles which can increase the excretion of EDCs or mitigate their harmful effects through the activation of mitohormesis or xenohormesis. Effectiveness of lifestyle interventions should be evaluated as practical ways against EDCs in the real world. PMID- 29589389 TI - Validity and Reliability of the Korean Version of the Hyperthyroidism Symptom Scale. AB - BACKGROUND: Thyrotoxicosis is a common disease resulting from an excess of thyroid hormones, which affects many organ systems. The clinical symptoms and signs are relatively nonspecific and can vary depending on age, sex, comorbidities, and the duration and cause of the disease. Several symptom rating scales have been developed in an attempt to assess these symptoms objectively and have been applied to diagnosis or to evaluation of the response to treatment. The aim of this study was to assess the reliability and validity of the Korean version of the hyperthyroidism symptom scale (K-HSS). METHODS: Twenty-eight thyrotoxic patients and 10 healthy subjects completed the K-HSS at baseline and after follow-up at Seoul National University Bundang Hospital. The correlation between K-HSS scores and thyroid function was analyzed. K-HSS scores were compared between baseline and follow-up in patient and control groups. Cronbach's alpha coefficient was calculated to demonstrate the internal consistency of K HSS. RESULTS: The mean age of the participants was 34.7+/-9.8 years and 13 (34.2%) were men. K-HSS scores demonstrated a significant positive correlation with serum free thyroxine concentration and decreased significantly with improved thyroid function. K-HSS scores were highest in subclinically thyrotoxic subjects, lower in patients who were euthyroid after treatment, and lowest in the control group at follow-up, but these differences were not significant. Cronbach's alpha coefficient for the K-HSS was 0.86. CONCLUSION: The K-HSS is a reliable and valid instrument for evaluating symptoms of thyrotoxicosis in Korean patients. PMID- 29589390 TI - High Brachial Ankle Pulse Wave Velocity as a Marker for Predicting Coronary Artery Stenosis in Patients with Type 2 Diabetes. AB - BACKGROUND: We evaluated the ability of brachial ankle pulse wave velocity (baPWV) to predict coronary artery stenosis (CAS) in patients with type 2 diabetes, and compared the predictive power of baPWV to that of well-known cardiovascular disease (CVD) risk calculators. METHODS: The study group included 83 consecutive patients over 30 years old with type 2 diabetes who complained of vague chest discomfort. An automatic pulse waveform analyzer was used to measure baPWV. CAS was measured using multi-slice computed tomographic (MSCT) angiography. RESULTS: Age, maximal baPWV, duration of diabetes, current smoking, the UK Prospective Diabetes Study (UKPDS) Risk Engine score, American College of Cardiology/American Heart Association (ACC/AHA) risk estimator score, the Framingham risk calculator score, and coronary artery calcium score were greater in patients with CAS than in those without CAS. An area under the curve (AUC) indicative of a predictive value for CAS (>=20%) was found for several parameters. The AUC of maximal baPWV, the UKPDS Risk Engine, the ACC/AHA ASCVD risk estimator, and the Framingham risk calculator were 0.672 (95% confidence interval [CI], 0.554 to 0.785; P=0.010), 0.777 (95% CI, 0.675 to 0.878; P<0.001), 0.763 (95% CI, 0.660 to 0.866; P<0.001), and 0.736 (95% CI, 0.629 to 0.843; P<0.001), respectively. The optimal cutoff value of baPWV for the detection of CAS was 1,650 cm/sec (sensitivity, 68.9%; specificity, 63.2%). CONCLUSION: Maximal baPWV was closely related with CAS detected by MSCT coronary angiography in patients with type 2 diabetes. baPWV has the potential to be a useful, noninvasive screening tool for the prediction of occult CAS in patients with type 2 diabetes. PMID- 29589391 TI - Effects of Serum Albumin, Calcium Levels, Cancer Stage and Performance Status on Weight Loss in Parathyroid Hormone-Related Peptide Positive or Negative Patients with Cancer. AB - BACKGROUND: A recent animal study showed that parathyroid hormone-related peptide (PTHrP) is associated with cancer cachexia by promoting adipose tissue browning, and we previously demonstrated that PTHrP predicts weight loss (WL) in patients with cancer. In this study, we investigated whether prediction of WL by PTHrP is influenced by clinical factors such as serum albumin, corrected calcium levels, cancer stage, and performance status (PS). METHODS: A cohort of 219 patients with cancer whose PTHrP level was measured was enrolled and followed for body weight (BW) changes. Subjects were divided into two groups by serum albumin (cutoff value, 3.7 g/dL), corrected calcium (cutoff value, 10.5 mg/dL), cancer stage (stage 1 to 3 or 4), or PS (Eastern Cooperative Oncology Group 0 to 1 or 2 to 4), respectively. Clinically significant WL was defined as either percent of BW change (% BW) <-5% or % BW <-2% plus body mass index (BMI) <20 kg/m2. RESULTS: After a median follow-up of 327 days, 74 patients (33.8%) experienced clinically significant WL. A positive PTHrP level was associated with a 2-fold increased risk of WL after adjusting for age, baseline BMI, serum albumin, corrected calcium level, cancer stage, and PS. The effect of PTHrP on WL remained significant in patients with low serum albumin, stage 4 cancer, and good PS. Regardless of calcium level, the effect of PTHrP on WL was maintained, although there was an additive effect of higher calcium and PTHrP levels. CONCLUSION: Early recognition of patients with advanced cancer who are PTHrP positive with hypercalcemia or hypoalbuminemia is needed for their clinical management. PMID- 29589392 TI - Pioglitazone Attenuates Palmitate-Induced Inflammation and Endoplasmic Reticulum Stress in Pancreatic beta-Cells. AB - BACKGROUND: The nuclear receptor peroxisome proliferator-activator gamma (PPARgamma) is a useful therapeutic target for obesity and diabetes, but its role in protecting beta-cell function and viability is unclear. METHODS: To identify the potential functions of PPARgamma in beta-cells, we treated mouse insulinoma 6 (MIN6) cells with the PPARgamma agonist pioglitazone in conditions of lipotoxicity, endoplasmic reticulum (ER) stress, and inflammation. RESULTS: Palmitate-treated cells incubated with pioglitazone exhibited significant improvements in glucose-stimulated insulin secretion and the repression of apoptosis, as shown by decreased caspase-3 cleavage and poly (adenosine diphosphate [ADP]-ribose) polymerase activity. Pioglitazone also reversed the palmitate-induced expression of inflammatory cytokines (tumor necrosis factor alpha, interleukin 6 [IL-6], and IL-1beta) and ER stress markers (phosphor eukaryotic translation initiation factor 2alpha, glucose-regulated protein 78 [GRP78], cleaved-activating transcription factor 6 [ATF6], and C/EBP homologous protein [CHOP]), and pioglitazone significantly attenuated inflammation and ER stress in lipopolysaccharide- or tunicamycin-treated MIN6 cells. The protective effect of pioglitazone was also tested in pancreatic islets from high-fat-fed KK Ay mice administered 0.02% (wt/wt) pioglitazone or vehicle for 6 weeks. Pioglitazone remarkably reduced the expression of ATF6alpha, GRP78, and monocyte chemoattractant protein-1, prevented alpha-cell infiltration into the pancreatic islets, and upregulated glucose transporter 2 (Glut2) expression in beta-cells. Moreover, the preservation of beta-cells by pioglitazone was accompanied by a significant reduction of blood glucose levels. CONCLUSION: Altogether, these results support the proposal that PPARgamma agonists not only suppress insulin resistance, but also prevent beta-cell impairment via protection against ER stress and inflammation. The activation of PPARgamma might be a new therapeutic approach for improving beta-cell survival and insulin secretion in patients with diabetes mellitus. PMID- 29589393 TI - A Comparison of Ultrasound-Guided Fine Needle Aspiration versus Core Needle Biopsy for Thyroid Nodules: Pain, Tolerability, and Complications. AB - BACKGROUND: To compare pain, tolerability, and complications associated with fine needle aspiration (FNA) versus core needle biopsy (CNB). METHODS: FNAs were performed using 23-gauge needles and CNBs were performed using 18-gauge double action spring-activated needles in 100 patients for each procedure. Patients were asked to record a pain score using a 10-cm visual analog scale and procedure tolerability. Complications and number of biopsies were recorded. RESULTS: The median pain scores were similar for the FNA and CNB approaches during and 20 minutes after the biopsy procedures (3.7 vs. 3.6, P=0.454; 0.9 vs. 1.1, P=0.296, respectively). The procedure was tolerable in all 100 FNA patients and in 97 CNB patients (P=0.246). The mean number of biopsies was fewer in the CNB group (1.4 vs. 1.2, P=0.002). By subgroup analysis (staff vs. non-staff), no significant difference was detected in any parameter. There were no major complications in either group, but three patients who underwent CNB had minor complications (P=0.246). CONCLUSION: FNA and CNB show no significant differences for diagnosing thyroid nodules in terms of pain, tolerability, or complications. PMID- 29589394 TI - Combined Effects of Baicalein and Docetaxel on Apoptosis in 8505c Anaplastic Thyroid Cancer Cells via Downregulation of the ERK and Akt/mTOR Pathways. AB - BACKGROUND: Anaplastic thyroid cancer (ATC) is one of the most lethal human malignancies. Docetaxel, a microtubule stabilizer, is a common chemotherapeutic agent used to treat various metastatic cancers. However, prolonged use results in various side effects and drug resistance. Flavonoids, such as baicalein, are accepted chemotherapeutic and dietary chemopreventive agents with many advantages, such as greater accessibility, affordability, and lower toxicity, compared with traditional chemotherapy agents. In this study, we evaluated whether baicalein enhances the effects of docetaxel on apoptosis and metastasis in 8505c ATC cells. METHODS: The 8505c cells were treated with baicalein or docetaxel individually and in combination. Cell viability was measured by MTT (thiazolyl blue tetrazolium bromide) assay, and apoptosis was detected by fluorescence microscopy of Hoechst-stained cells. The expression of apoptotic (Bax and caspase-3), anti-apoptotic (Bcl-2), angiogenic (vascular endothelial growth factor [VEGF], transforming growth factor beta [TGF-beta], E-cadherin, and N-cadherin), and signaling (extracellular signal-regulated kinase [ERK] mitogen activated protein kinase [MAPK], Akt, and mammalian target of rapamycin [mTOR]) proteins was determined by Western blot analysis. RESULTS: The combination of baicalein (50 or 100 MUM) and docetaxel (10 nM) significantly inhibited proliferation and induced apoptosis compared with monotherapies. The combination treatment significantly inhibited the expression of Bax, caspase-3, VEGF, TGF beta1, E-cadherin, N-cadherin, and mTOR, but decreased the expression of Bcl-2 and significantly decreased the phosphorylation of ERK and Akt. CONCLUSION: The combination of baicalein and docetaxel effectively induced apoptosis and inhibited metastasis in 8505c cells through downregulation of apoptotic and angiogenic protein expression and blocking of the ERK and Akt/mTOR pathways in 8505c cells. These results suggest that baicalein enhances the anticancer effects of docetaxel in ATC.

PMID- 29589397 TI - Perspectives and unmet needs in polymyalgia rheumatica. Providing the fundamental framework for the development of new treatment regimes in polymyalgia rheumatica. AB - Polymyalgia rheumatica is effectively treated with glucocorticoids. However, glucocorticoid treatment can cause numerous and potentially serious side effects. Therefore, lowest effective dose and shortest duration to control disease is aimed for and glucocorticoid-sparing treatments are needed. Nevertheless, development of treatment regimens in PMR has been hampered by the lack of reliable classification criteria and evidence-based outcome measures. In this editorial, we discuss the need for valid classification criteria in PMR, the strengths and limitations of the ACR/EULAR 2012 provisional classification criteria for PMR and the need of validation and possible refining of the criteria. PMID- 29589398 TI - Pathogenesis of polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is a chronic, inflammatory disorder of unknown cause, almost exclusively occurring in people aged over 50 and often associated with giant cell arteritis. The evidence that PMR occurs almost exclusively in individuals aged over 50 may indicate that age-related immune alterations in genetically predisposed subjects contribute to development of the disease. Several infectious agents have been investigated as possible triggers of PMR even though the results are inconclusive. Activation of the innate and adaptive immune systems has been proved in PMR patients as demonstrated by the activation of dendritic cells and monocytes/macrophages and the altered balance between Th17 and Treg cells. Disturbed B cell distribution and function have been also demonstrated in PMR patients suggesting a pathogenesis more complex than previously imagined. In this review we will discuss the recent findings regarding the pathogenesis of PMR. PMID- 29589399 TI - Contribution of the new 2012 EULAR/ACR classification criteria for the diagnosis of polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is one of the most common rheumatic inflammatory disorders in people aged over 50. It is characterized by aching and prolonged morning stiffness in the shoulder and pelvic girdles and neck. To date there are no specific diagnostic tests, and in clinical practice the diagnosis of PMR remains based on its characteristic clinical manifestations, laboratory evidence of systemic inflammation, rapid response to low doses of glucocorticoids and exclusion of other disorders that may present with proximal pain and stiffness. For classification purposes, several criteria have been proposed over time based on retrospective clinical series, but none have been validated and received universal acceptance. Recently, an international collaborative initiative between the EULAR and the ACR was undertaken to develop new polymyalgia rheumatica classification criteria. In this review, the provisional 2012 EULAR/ACR classification criteria will be presented and their contribution for the diagnosis of polymyalgia rheumatica will be discussed. PMID- 29589400 TI - The real evidence for polymyalgia rheumatica as a paraneoplastic syndrome. AB - The aim of this study was to systematically consider the evidence for polymyalgia rheumatica (PMR) as a paraneoplastic disease. A systematic review of Medline and Embase was conducted from their inception to February 2017. Risk of bias was assessed using the Newcastle-Ottawa tool. Data were extracted regarding the PMR cancer association, the types of cancer associated with PMR and the presentation of PMR patients subsequently diagnosed with cancer. Twenty-three full text articles were reviewed from the 1174 unique references identified in the search. Nine articles were included in the final review. There was some evidence of an association between PMR and cancer in the short-term (first 6 to 12 months after diagnosis), but no evidence of an association after this time. Limited evidence suggests that lymphoma, prostate and haematological cancers may be those cancers more commonly diagnosed in those with PMR. There was little evidence to suggest what presenting features may be associated with the development of cancer. There is little evidence of PMR as a true paraneoplastic disease. However, there is reason to be cautious when making the diagnosis of PMR. Clinicians should be aware of this potential association both prior to making a diagnosis and throughout the course of the condition. PMID- 29589401 TI - Comorbidity in polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is the commonest inflammatory rheumatic disease affecting older people. The current mainstay of treatment is long-term oral glucocorticoid therapy. Management of these patients in clinical practice is often complicated by the presence of comorbidity. Comorbidity might be due to shared risk factors such as age, sex, or genetic background; to the presence of the disease itself; or to adverse effects of glucocorticoid therapy. Cardiovascular disease, osteoporosis/fracture, metabolic and ocular comorbidity are of particular interest to clinicians because of their relationship to glucocorticoid therapy and the relevance to clinical treatment decisions regarding glucocorticoid tapering. Patients at high risk of exacerbation of comorbidity by glucocorticoid therapy may be considered for adjunctive steroid sparing therapies and thus may need specialist management. From a public health perspective, with the ageing population the prevalence of PMR is predicted to increase; accurate data on comorbidity will be needed for planning and delivery of healthcare services. PMID- 29589402 TI - The role of the general practitioner and the out-of-hospital public rheumatologist in the diagnosis and follow-up of patients with polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is a chronic inflammatory disease characterized by shoulder and pelvic girdle pain. Its onset peaks around the age of 75; the prevalence increases until the age of 90 and it is more frequent in females. Diagnosis is mostly performed on the basis of symptoms. An increase of serum inflammatory markers is indicative, but not essential, while therapy is mainly based on glucocorticoids. Since there is no universal agreement about diagnostic criteria for PMR, its detection is still difficult. There are discordant opinions about the fact that PMR can be recognised and managed by general practitioners (GPs), while patients with atypical features need to be referred to the rheumatologist. In the Italian setting, the absence of recent epidemiological studies is associated with the total lack of a research protocol in primary care, from which relevant information could be derived. The out-of-hospital public rheumatologist is a peculiar figure of the Italian National Health System, who takes care of outpatients. Although differences between the different Italian regional health services exist, this professional figure has proved to be effective in reducing delay and increasing accuracy in PMR diagnosis. PMID- 29589403 TI - Imaging in polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is a chronic, inflammatory disorder of unknown cause clinically characterized by pain and prolonged morning stiffness affecting the shoulders and often the pelvic girdle and neck. Imaging has substantially contributed to defining PMR as a disease mainly involving extra-articular structures. This review article analyses the role of the different imaging techniques in the diagnosis and follow-up of patients with PMR with particular emphasis on the role of ultrasound, PET/CT and MRI. PMID- 29589404 TI - Update on treatment of polymyalgia rheumatica. AB - Polymyalgia rheumatica (PMR) is the second most common inflammatory rheumatic disease in the elderly after rheumatoid arthritis. It is clinically characterised by pain and stiffness in the neck, proximal shoulder and hip girdle. Glucocorticoids (GCs) are the cornerstone of PMR treatment, but they are associated with potentially severe side effects. Among GC-sparing agents, methotrexate revealed a modest benefit in clinical trials, and recently, there have been promising reports from tocilizumab. In this review, we summarize the available evidence on the treatment of PMR and the possible role in the future of other agents under investigation. PMID- 29589405 TI - Static and dynamic plantar pressure distribution in amateur marathon runners. AB - BACKGROUND: The aim of the study was to compare the static and dynamic plantar pressure profiles of amateur marathon runners with sedentary cohorts. RESEARCH QUESTIONS: Are there differences in the plantar pressures of these two populations? Is there a correlation between body mass and BMI with plantar loading? METHODS: The study involved 43 runners involved in marathon training and 30 age-matched untrained individuals. Plantar pressure was measured using a baropodometric system. RESULTS: The marathon runners showed greater forefoot plantar pressure of the dominant extremity in the static condition and reduced medial plantar pressure of both extremities in the dynamic condition. A correlation was observed between body mass and BMI with mean plantar pressure only in the marathon group and only for the dominant extremity in the dynamic condition. CONCLUSIONS: Marathon training may modify the forefoot plantar loading characteristics of the dominant extremity during static conditions and increase lateral plantar pressure of both extremities in a dynamic (gait) condition. PMID- 29589406 TI - Improved cardiorespiratory fitness following moderate exercise may encourage inactive people for doable and sustainable behavioral change. AB - BACKGROUND: Global physical inactivity pandemic is responsible for more than 5 million deaths annually through its effects on non-communicable diseases. This requires urgent intervention. OBJECTIVE: To investigate associations of physical activity with cardiovascular fitness in a cross-sectional retrospective observational study. Data were collected for 21 years from 2530 healthy volunteers and athletes representing the entire spectrum of physical activity from the totally inactive sedentary persons to the highly trained national athletes. METHODS: Cardiac fitness was investigated echocardiographically, which is characterized by reduced resting heart rate (RHR), increased relative left ventricular muscular mass (rLVMM), improved left ventricular diastolic function (characterized by the ratio of early to late ventricular peak velocities, E/A) and peak exercise oxygen consumption. RESULTS: We found that even moderate exercise is associated with improved cardiac characteristics. With increasing exercise level, the RHR decreased from 69 to 63.3*, 61.4, 58.6*, 56.1 and 55.8/min in the non-athletes, leisure athletes, lower class athletes, 2nd class athletes, 1st class athletes and national athletes, respectively.b While the rLVMM was increased from 64.6 to 70.7*, 76.3*, 78.5, 86.7*and 88.9 in the same groups. The E/A ratio also increased from 1.71 to 1.72, 1.85*, 2.04* in the non athletes, leisure athletes, lower class athletes, and 2nd class athletes, respectively, but then decreased to 1.92 and 1.98 in the 1st class athletes and national athletes. The largest exerciseinduced improvement of cardiac fitness was observed between the inactive and the least active group, which didn't increase further in the highly trained national athletes enduring up to 20 training hours per week. CONCLUSIONS: Our findings indicate that cardiac fitness can be improved by moderate exercise in sedentary persons. This information would help physicians to encourage inactive patients, who find physical exercise intimidating, for doable and sustainable behavioral change. PMID- 29589407 TI - Validity and reliability of an inertial device (WIMU PROTM) to quantify physical activity level through steps measurement. AB - BACKGROUND: Currently, there is an increase in the application of accelerometers to quantify physical activity level through daily steps, and therefore, it is required that the devices are valid and reliable. The current study tested (i) the validity of the WIMU PROTM inertial device in steps detection and (ii) the inter-device reliability for steps measurement. METHODS: Ten endurance-trained men volunteered to participate in this study (height: 1.78 +/- 0.05 m; body mass: 72.96 +/- 4.2 kg). Twelve trials of 40.32 m at different speeds (four trials at each speed) were performed: (a) walking (<5 km/h), (b) jogging (5-10 km/h) and running (10-15 km/h). The video analysis was used as criterion to assess validity, while, two WIMU PROTM inertial devices were compared to assess between- unit reliability. RESULTS: A near-perfect validity between video analysis and WIMU PROTM (ICC = 0.999; Bias = 0.03) and a very good reliability between WIMU PROTM devices (Bias = -0.01; CV = 0.02%) was found. The highest values were found at walking (ICC = 0.999) and the lowest values were found at running (ICC = 0.995). CONCLUSIONS: WIMU PROTM is a reliable and valid device to quantify physical activity level through steps measurement. PMID- 29589408 TI - High-intensity interval training in overweight and obese children and adolescents: systematic review and meta-analysis. AB - INTRODUCTION: While High Intensity Interval Training is praised in many populations for its beneficial effects on body composition and cardiometabolic health, its use among obese youth remain uncertain. This study aimed at determining whether HIIT is effective to improve aerobic fitness and reduce cardiometabolic risk factors in overweight and obese youth. EVIDENCE ACQUISITION: A systematic search was conducted and articles reporting studies that investigated the effects of HIIT in 6 to 18-year-old youth were eligible. Meta analyses were performed when appropriate. EVIDENCE SYNTHESIS: 15 studies were included for the systematic review and meta-analyses. HIIT significantly improves maximal oxygen uptake [1.117 (95% CI=0.528 to 1.706), p<0.001], and reduces body mass [-0.295 (95%CI =-0.525 to -0.066), p<0.05], body fat [-0.786 (95%CI =-1.452 to - 0.120), p<0.05], systolic and diastolic blood pressure [-1.026 (95% CI = 1.370 to -0.683), p<0.001; - 0.966 (95% CI =-1.628 to -0.304), p<0.01 respectively], and the HOMA-IR [-1.589 (95%CI =-2.528 to -0.650), p<0.01]. However, there is significant heterogeneity, and low to high inconsistency for most cardiometabolic risk factors and aerobic fitness. CONCLUSIONS: Although few studies have reported cardiometabolic risks, HIIT may also be as effective as traditional endurance continuous training to decrease blood pressure and insulin resistance. HIIT is effective to improve aerobic fitness, body composition, and cardiometabolic risk factors in obese youth, but data are insufficient to determine whether it is more effective than traditional continuous submaximal intensity exercise training. PMID- 29589409 TI - Physical fitness characteristics of Omani primary school children according to body mass index. AB - BACKGROUND: There is evidence that children with high cardiorespiratory fitness and normal body mass index (BMI) have less risk of non communicable diseases (NCDs), however limited research was undertaken in Omani children. Therefore the aims of the present study were to describe body composition and physical fitness of a large cohort of Omani school children of both genders, and to investigate the effects of weight status on physical fitness. METHODS: Three hundred and fourteen Omani school children aged 9 to 10 years old took part in anthropometric assessments, body composition and fitness tests, including handgrip strength, the basketball chest pass, broad jump, 20-m sprint, four 10-m shuttle agility, 30-s sit-up, and multistage fitness test (MSFT). RESULTS: Obese boys and girls performed worse than normal-weight children in sprint, agility and endurance. In addition, fitness measures in the overweight group and underweight groups were not significantly different from other groups, except a better handgrip strength and poorer MSFT in overweight compared to normal weight girls, and poorer agility performance in underweight girls compared to the three other groups. CONCLUSIONS: Most fitness measures are lower in obese Omani children, which suggests that they will be more at risk of developing NCDs later in life.

AB - BACKGROUND: Proprioception and vertical jump are important parameters in the performance and prevention of injuries in futsal. However, very few studies have analyzed the role of multi-station exercises to improve these variables. The purpose of this study was to assess the effects of a six-week multi-station exercise program on knee joint position sense (JPS) and countermovement jump (CMJ) of futsal players. METHODS: Thirty-four male futsal players randomly classified into experimental (n = 17) or control group (n = 17). The experimental group included a multi-station exercise protocol to their training routines (2 times/week - 6 weeks); the control group continued their training routines. All the players completed similar training routines outside of the multi-station exercises. Before (baseline), just after the intervention (Post6Wk) and four weeks later (Post10Wk), CMJ and knee JPS (absolute, relative and variable angular error: AAE, RAE and VAE, respectively) were evaluated. RESULTS: ANOVA showed that the experimental group significantly decreased VAE at Post10Wk compared to baseline, suggestive of greater proprioceptive precision, while the control group significantly increased AAE, RAE and VAE at Post10Wk compared to baseline. The experimental group exhibited lower and thus, better AAE and VAE than the control group at Post10Wk, although no significant differences were found at Post6Wk. No significant differences was found in the CMJ. CONCLUSIONS: A six weeks of multi station program may help improve proprioceptive precision of futsal players, even one month after finishing the 6-wk multi-station training program. However, this is not long enough to improve proprioceptive acuity and maximum vertical jump. Therefore, the meaningful of these results in term of performance are unclear. PMID- 29589411 TI - Dietetic- nutritional, physical and physiological recovery methods post competition in team sports. A review. AB - INTRODUCTION: To a proper recovery, is absolutely necessary to know that athletes with enhanced recovery after maximal exercise are likely to perform better in sports. Recovery strategies are commonly used in team sports despite limited scientific evidence to support their effectiveness in facilitating optimal recovery and the players spend a much greater proportion of their time recovering than they do in training. EVIDENCE ACQUISITION: According to authors, some studies investigated the effect of recovery strategies on physical performance in team sports, lack of experimental studies about the real origin of the fatigue, certify the need for further study this phenomenon. EVIDENCE SYNTHESIS: Thus, developing effective methods for helping athletes to recover is deemed essential. CONCLUSIONS: Therefore, the aim of this review is provide information for his practical application, based on scientific evidence about recovery in team sports. PMID- 29589412 TI - The validity and reliability of the my jump 2 app for measuring the reactive strength index and drop jump performance. AB - BACKGROUND: This is the first study to independently assess the concurrent validity and reliability of the My Jump 2 app for measuring drop jump performance. It is also the first to evaluate the app's ability to measure the reactive strength index (RSI). METHODS: Fourteen male sport science students (age: 29.5 +/- 9.9 years) performed three drop jumps from 20 cm and 40 cm (totalling 84 jumps), assessed via a force platform and the My Jump 2 app. Reported metrics included reactive strength index, jump height, ground contact time, and mean power. Measurements from both devices were compared using the intraclass correlation coefficient (ICC), Pearson product moment correlation coefficient (r), Cronbach's alpha (alpha), coefficient of variation (CV) and BlandAltman plots. RESULTS: Near perfect agreement was seen between devices at 20 cm for RSI (ICC = 0.95) and contact time (ICC = 0.99) and at 40 cm for RSI (ICC = 0.98), jump height (ICC = 0.96) and contact time (ICC = 0.92); with very strong agreement seen at 20 cm for jump height (ICC = 0.80). In comparison with the force plate the app showed good validity for RSI (20 cm: r = 0.94; 40 cm; r = 0.97), jump height (20 cm: r = 0.80; 40 cm; r = 0.96) and contact time (20 cm = 0.96; 40 cm; r = 0.98). CONCLUSIONS: The results of the present study show that the My Jump 2 app is a valid and reliable tool for assessing drop jump performance. PMID- 29589413 TI - Physiological demands of daily riding gaits in jockeys. AB - BACKGROUND: Jockeys should maintain a high level of physical fitness to meet the physical demands of horse racing. The aim of this study was to determine the physiological requirements of the riding gaits used regularly in training. METHODS: Eleven trainee jockeys performed a maximal incremental Wattbike cycle ergometer test. Mean absolute and relative oxygen uptake (VO2) and heart rate (HR) were recorded for the steady-state period during a walk, trot and canter. Energy expenditure (EE) and associated metabolic equivalent (MET) were also estimated. RESULTS: During a walk, trot and canter, relative mean VO2 corresponded to 15 +/- 4%, 38 +/- 6%, 47 +/- 9% of VO2peak and mean HR corresponded to 48 +/- 6%, 60 +/- 6%, 71 +/- 7% of HRpeak respectively. Mean VO2 and mean HR were significantly different amongst gaits; p <= 0.001. Walking required the lowest estimated EE of 2.25 +/- 0.6 kcal.min-1 (p <= 0.001; 2.4 METs;) and it was significantly lower than trotting at 5.72 +/- 1.0 kcal.min-1 (p <= 0.001; 6.2 METs) and cantering at 7.10 +/- 1.8 kcal.min-1 (p <= 0.001; 7.7 METs;). CONCLUSIONS & PRACTICAL APPLICATIONS: These riding activities are associated with relatively low physiological demand and alternate modes of exercise are recommended for trainee jockeys to ensure the demands of racing are met. Future research should investigate the physical training, both riding specific and general conditioning, jockeys perform in preparation for racing. PMID- 29589414 TI - Comparison of axillary nerve block duration using mepivacaine in non-insulin diabetic or renal insufficiency patients: a controlled observational matched multicentre trial. AB - BACKGROUND: Although studies in diabetic patients demonstrated delayed recovery after long-acting local anesthetic, its effects with short-acting LA remains to be determined. Using mepivacaine, the authors evaluated the duration of axillary nerve blocks in diabetic (DP), renal failure (creatinine clearance < 30 ml.min-1) (RP) and healthy patients (HP). METHOD: We prospectively included consecutive patients aged 18-80 years, with DP (n=37), RP (n=32) and HP (n=48) scheduled for distal upper limb surgery. Before surgery, an axillary nerve block (20 mL mepivacaine 15 mg.mL-1) was performed with an ultrasound approach combined with nerve stimlulation. Five mL was injected for each nerve: median, ulnar, radial, musculo-cutaneaous nerves. The primary endpoint measured was the duration of sensory block. For statistical analysis, each HP patient was matched with RP and DP patient (1:1),with regards to age (range +/- 5 years) and sex. RESULTS: Patient characteristics were similar between groups. Creatinine clearance was 14+/-8 mL.min-1 in RP group and HbA1c (%) was 7.5+/-1.5 in DP group. Mean duration of diabetic or renal insufficiencey illness were respectively 8 and 12 years. Onset time for sensory and motor blocks were similar between groups. Average time for sensory block duration was similar between DP vs HP (235 +/- 52 vs 230 +/- 54 min, p=0.71) ; and between RP vs HP (234 +/- 51 vs 229 +/- 57 min, p=0.65). CONCLUSIONS: The short-acting LA (mepivacaine) are associated with similar pharmacodynamic effects in diabetic and renal failure patients as compared with healthy patients. PMID- 29589415 TI - Perioperative hyperglycemia and neurocognitive outcome after surgery: a systematic review. AB - INTRODUCTION: Preliminary evidence suggest a possible relationship between perioperative hyperglycemia, postoperative delirium (POD) or cognitive dysfunction (POCD). We aim to present the available clinical evidence related to chronic (i.e. diabetes mellitus) or acute perioperative hyperglycemia as risk factors for POD/POCD. EVIDENCE ACQUISITION: A literature search of EMBASE (via Ovid, 1974-present) online medical database and MEDLINE (via PubMed or Ovid, 1946 present) was performed. All types of clinical studies including randomized controlled trials, prospective, as well as retrospective cohort studies were screened. Clinical studies that reported original information on the relationship between diabetes mellitus (DM) and/or acute perioperative abnormal glucose levels and POD or POCD were selected. Reviews and editorials (i.e. articles not presenting original preclinical or clinical research) were excluded and case reports were not considered for analysis. EVIDENCE SYNTHESIS: Our search resulted in 2356 papers for screening, from which we selected 29 studies that met our inclusion criteria. DM was investigated in 24 observational papers, acute perioperative hyperglycemia in six observational studies and two randomized controlled trials examined the effect of perioperative glucose lowering on POD/POCD. Diabetes was associated with POD or POCD in 18/24 observational studies and 6/6 of the included observational studies found that perioperative hyperglycemia was associated with POD/POCD, independent of diabetes. The two randomized controlled trials had a different trial design and reported conflicting results. CONCLUSIONS: According to the available evidence, DM and acute perioperative hyperglycemia may be associated with an increased risk for POD/POCD. These conclusions are based mostly on observational studies and deserve more and dedicated research. This systematic review may direct the design of future studies. PMID- 29589416 TI - Conscious sedation in critically ill patients is associated with stressors perception lower than assessed by caregivers. AB - BACKGROUND: In ICU, the stay is frequently a stressful experience. Caregivers may help to understand patients' perceptions; however, their reliability is uncertain. Despite the recent recommendations of lighter sedation targets, little is known about the impact of "conscious sedation" on ICU patients memories. Purpose of this prospective, observational study is to analyze the stress perception in consciously-sedated ICU-patients, comparing it to caregivers and staff members. METHODS: Twenty-nine high-risk ICU-patients treated with awake/cooperative sedation were enrolled. Before discharge, patients received a validated questionnaire for ICU stressors evaluation, also administered to their main caregiver (N.=29), to caregivers of other ICU patients not enrolled in the study (N.=33) and to staff members (ICU nurses, attending physicians, residents, medical students, N.=56). RESULTS: Total stress score was: patients 141+/-41, patient relatives 210+/-63, other relatives: 202+/-73, ICU staff: 232+/-44, P<0.001. Among patients, older age (P=0.031), longer ICU-stay (P=0.018) and awake sedation (P=0.022) were associated with lower stress; sex and illness severity had no effect; mechanical ventilation length (P=0.021) and agitation (P=0.029) were associated with higher stress. Nurses tended to overestimate stressors more than attending physicians and trainees. Within staff members, age (P=0.021) and years of experience (P=0.069) were positively associated with overestimation. CONCLUSIONS: Conscious sedation is associated with stress perception lower than stress assessed by caregivers: relatives and staff members tend to overestimate ICU patient stress, more so with increasing age or expertise. A number of stressors underestimated by staff and families could be target of specific interventions to ameliorate quality of life during ICU stay. PMID- 29589417 TI - Blocking around the transversalis fascia: behind the scene. AB - BACKGROUND: The transversalis fascia plane and the quadratus lomborum blocks target the branches of T12-L1 nerves and provide analgesia in patients undergoing surgery involving the corresponding dermatomes. The transversalis fascia is believed to contribute to determine the spread of local anesthetic in such blocks. Nonetheless, the anatomy of this fascia and its possible role in these blocks still have to be precisely defined. METHODS: We conducted a series of 10 dissections and full-thickness specimens were obtained from one side for the microscopic analysis. RESULTS: Macroscopic study showed failed to identify a distinguishable fascial structure between the fascia of the transversus abdominis muscle and the peritoneum. Microscopic examination showed the presence of a further fascial layer (0.1-0.2 mm), ascribable to transversalis fascia. Transversalis fascia and transversus abdominis epimysium posteriorly diverge: transversus epimysium goes posteriorly to quadratus lomborum to joint the oblique internal aponeurosis, while transversalis fascia continues in front to quadratus lomborum. So, a little fascial triangle (2-3 mm) is formed on the lateral border of quadratus lomborum, defined by transversalis fascia and transversus abdominis. Inside this triangle, T12 and L1 nerves are present. CONCLUSIONS: Considering the thinness of the transversalis fascia and the small size of the triangular space that contains the target nerves, this is most likely a virtual, ideal rather than realistic injection site. Accordingly, it is probable that the local anesthetic is injected in the much wider retroperitoneal space and reaches the nerves by spreading backwards through the thin transversalis fascia. PMID- 29589418 TI - Myocardial injury after non-cardiac surgery: a perioperative affair? AB - Myocardial injury after non-cardiac surgery (MINS) is a rather new nosological entity and an unfortunately common perioperative complication. The diagnostic criteria for MINS, also indicated as isolated myocardial injury (IMI), are an elevated postoperative high sensitivity troponin T (hsTnT level ranging between 20 and 65 ng/L with an absolute change of at least 5 ng/L or hsTnT level >65 ng/L), in absence of symptoms and/or EKG findings suggestive of ischemia and without a non-ischemic etiology causing troponin elevation. MINS does not fulfill the universal definition of myocardial infarction even if it is related to ischemic causes and it is independently associated with 30-day postoperative mortality and complications. Nevertheless, mortality at 30 days in MINS patients has been calculated up to 10% and it increases exponentially as a function of peak postoperative troponin concentration. Physician and researchers should discriminate MINS from perioperative myocardial infarction and from not ischemic troponin increases. In the postoperative period, the possibility of missing the diagnosis of an acute coronary syndrome for the paucity of clinical symptoms or because physician failed to evaluate a postoperative EKG recording should always be considered. Physiopathology of MINS is not yet well defined: current hypotheses are surrogated from perioperative myocardial infarction studies. Up to now there are not specific treatments for MINS, even if antithrombotic therapy is under evaluation. Treatment decisions should be tailored to the individual case; potential benefits of troponin screening include a cardiology consultation and consequently, improved patients' information to promote lifestyle changes and enhanced therapy. PMID- 29589419 TI - Influence of head and neck position on performance of the Ambu(r) AuraGainTM laryngeal mask: a randomised crossover study. AB - BACKGROUND: The purpose of this study was to investigate the influence of different head and neck positions on the performance of the Ambu(r) AuraGainTM, a novel laryngeal mask with anatomical curvature. METHODS: Oropharyngeal leak pressure, expiratory tidal volume, peak inspiratory pressure, ventilation score, and fibreoptic view score through the AuraGainTM were measured in the neutral, flexed, and extended neck positions as well as the right rotated head and neck position in each patient in a random order. A total of 40 patients were enrolled, and data from 39 patients were analysed. RESULTS: Oropharyngeal leak pressure was significantly higher in the flexed neck position (32.1+/-7.2 cmH2O, 95% CI of mean difference [3.3 to 7.8], P<0.001) and lower in the extended neck position (22.0+/-6.8 cmH2O, 95% CI of mean difference [-7.0 to -2.0], P=0.001) compared with those in the neutral position (26.6+/-7.5 cmH2O). The ventilation score was comparable in all positions. The fibreoptic view score was higher in the extended neck position (P<0.001) and right rotated head and neck position (P<0.001) compared with that in the neutral position; the vocal cords were most easily visualized in the extended neck position. CONCLUSIONS: Head and neck positions affect the oropharyngeal seal of the AuraGainTM, as evidenced by the oropharyngeal leak pressure, but not enough to impede positive-pressure ventilation. Neck flexion can be used when a better oropharyngeal seal is needed, and neck extension and right rotation of the head and neck may facilitate endotracheal intubation using the AuraGainTM as a conduit.

PMID- 29589429 TI - Core-Sheath Paraffin-Wax-Loaded Nanofibers by Electrospinning for Heat Storage. AB - Paraffin wax (PW) is widely used for smart thermoregulation materials due to its good thermal performance. However, the leakage and low thermal conductivity of PW hinder its application in the heat storage field. Accordingly, developing effective methods to address these issues is of great importance. In this study, we explored a facile approach to obtain PW-loaded core-sheath structured flexible nanofibers films via coaxial electrospinning technique. The PW as the core layer was successfully encapsulated by the sheath-layer poly(methyl methacrylate). The diameter of the fiber core increased from 395 to 848 nm as the core solution speed rate increased from 0.1 to 0.5 mL/h. In addition, it can be seen that higher core solution speed rate could lead to higher PW encapsulation efficiency according to the transmission electron microscopy results. The core-sheath nanofiber films, moreover, possessed the highest latent heat of 58.25 J/g and solidifying enthalpy of -56.49 J/g. In addition, we found that after 200 thermal cycles, there was little change in latent heat, which demonstrated that it is beneficial for the PW-loaded core-sheath structure to overcome the leakage issue and enhance thermal stability properties for the thermoregulation film. PMID- 29589430 TI - Facile Method and Novel Dielectric Material Using a Nanoparticle-Doped Thermoplastic Elastomer Composite Fabric for Triboelectric Nanogenerator Applications. AB - The trends toward flexible and wearable electronic devices give rise to the attention of triboelectric nanogenerators (TENGs) which can gather tiny energy from human body motions. However, to accommodate the needs, wearable electronics are still facing challenges for choosing a better dielectric material to improve their performance and practicability. As a kind of synthetic rubber, the thermoplastic elastomer (TPE) contains many advantages such as lightweight, good flexibility, high tear strength, and friction resistance, accompanied by good adhesion with fabrics, which is an optimal candidate of dielectric materials. Herein, a novel nanoparticle (NP)-doped TPE composite fabric-based TENG (TF-TENG) has been developed, which operates based on the NP-doped TPE composite fabric using a facile coating method. The performances of the TENG device are systematically investigated under various thicknesses of TPE films, NP kinds, and doping mass. After being composited with a Cu NP-doped TPE film, the TPE composite fabric exhibited superior elastic behavior and good bending property, along with excellent flexibility. Moreover, a maximum output voltage of 470 V, a current of 24 MUA, and a power of 12 mW under 3 MOmega can be achieved by applying a force of 60 N on the TF-TENG. More importantly, the TF-TENG can be successfully used to harvest biomechanical energy from human body and provides much more comfort. In general, the TF-TENG has great application prospects in sustainable wearable devices owing to its lightweight, flexibility, and high mechanical properties. PMID- 29589431 TI - Reconstructing Space- and Energy-Dependent Exciton Generation in Solution Processed Inverted Organic Solar Cells. AB - Photon absorption-induced exciton generation plays an important role in determining the photovoltaic properties of donor/acceptor organic solar cells with an inverted architecture. However, the reconstruction of light harvesting and thus exciton generation at different locations within organic inverted device are still not well resolved. Here, we investigate the film depth-dependent light absorption spectra in a small molecule donor/acceptor film. Including depth dependent spectra into an optical transfer matrix method allows us to reconstruct both film depth- and energy-dependent exciton generation profiles, using which short-circuit current and external quantum efficiency of the inverted device are simulated and compared with the experimental measurements. The film depth dependent spectroscopy, from which we are able to simultaneously reconstruct light harvesting profile, depth-dependent composition distribution, and vertical energy level variations, provides insights into photovoltaic process. In combination with appropriate material processing methods and device architecture, the method proposed in this work will help optimizing film depth-dependent optical/electronic properties for high-performance solar cells. PMID- 29589432 TI - High-Performance Organic Photodetectors from a High-Bandgap Indacenodithiophene Based pi-Conjugated Donor-Acceptor Polymer. AB - A conjugated donor-acceptor polymer, poly[4,4,9,9-tetrakis(4-hexylphenyl)-4,9 dihydro- s-indaceno[1,2- b:5,6- b']dithiophene-2,7-diyl- alt-5-(2-ethylhexyl)-4 H thieno[3,4- c]pyrrole-4,6(5 H)-dione-1,3-diyl] (PIDT-TPD), is blended with the fullerene derivative [6,6]phenyl-C61-butyric acid methyl ester (PC61BM) for the fabrication of thin and solution-processed organic photodetectors (OPDs). Systematic screening of the concentration ratio of the blend and the molecular weight of the polymer is performed to optimize the active layer morphology and the OPD performance. The device comprising a medium molecular weight polymer (27.0 kg/mol) in a PIDT-TPD:PC61BM 1:1 ratio exhibits an external quantum efficiency of 52% at 610 nm, a dark current density of 1 nA/cm2, a detectivity of 1.44 * 1013 Jones, and a maximum 3 dB cutoff frequency of 100 kHz at -5 V bias. These results are remarkable among the state-of-the-art red photodetectors based on conjugated polymers. As such, this work presents a functional organic active material for high-speed OPDs with a linear photoresponse at different light intensities. PMID- 29589433 TI - Sensitivity-Tunable Colorimetric Detection of Chloropicrin Vapor on Nylon-6 Nanofibrous Membrane Based on a Detoxification Reaction with Biological Thiols. AB - Detoxification reaction of chloropicrin in the human body with biological thiols was selected for detection of chloropicrin in the air. The consumption of free sulfhydryl group in biological thiols by chloropicrin is colorimetrically detectable with the addition of the Ellman's reagent. In this study, glutathione, N-acetyl-l-cysteine, l-homocysteine, cysteamine, and thioglycolic acid were tested as sensing agents for chloropicrin vapor detection in ppb concentration range. The reactivity of the selected biological thiols was investigated based on both their redox properties and the nucleophilic strength of the sulfhydryl groups. Nylon-6 nanofibrous membrane and an organic solvent were used as a sensor matrix and a vapor sorbent, respectively, to provide solid supports with ultrahigh surface area and enhanced adsorption to chloropicrin vapor. The tunable sensitivity and detection range by using different biological thiols was achieved on the sensors due to the different reactivity of thiols toward chloropicrin. PMID- 29589434 TI - Enhancement in Open-Circuit Voltage in Organic Solar Cells by Using Ladder-Type Nonfullerene Acceptors. AB - The open-circuit voltage ( Voc) loss has always been a major factor in lowering power conversion efficiencies (PCEs) in bulk heterojunction organic photovoltaic cells (OPVs). A method to improve the Voc is indispensable to achieve high PCEs. In this paper, we investigated a series of perylene diimide-based ladder-type molecules as electron acceptors in nonfullerene OPVs. The D-A ladder-type structures described here lock our pi-systems into a planar structure and eliminate bond twisting associated with linear conjugated systems. This enlarges the interface energy gap (Delta EDA), extends electronic delocalization, and hence improves the Voc. More importantly, these devices showed an increase in Voc without compromising either the Jsc or the FF. C5r exhibited a strong intermolecular interaction and a PCE value of 6.1%. Moreover, grazing-incident wide-angle X-ray scattering analysis and atomic force microscopy images suggested that our fused-ring acceptors showed a suitable domain size and uniform blend films, which were not affected by their rigid molecular structures.

The proposed smartphone based analysis system provides a user-friendly approach to design tools of personal health monitoring for reporting the presence of gold ions in human urine. PMID- 29589436 TI - Biotoxin Tropolone Contamination Associated with Nationwide Occurrence of Pathogen Burkholderia plantarii in Agricultural Environments in China. AB - Tropolone, a biotoxin produced by the agricultural pathogen Burkholderia plantarii, exerts cytotoxicity toward a wide array of biota. However, due to the lack of quantitative and qualitative approach, both B. plantarii occurrence and tropolone contamination in agricultural environments remain poorly understood. Here, we presented a sensitive and reliable method for detection of B. plantarii in artificial, plant, and environmental matrices by tropolone-targeted gas chromatography-triple-quadrupole tandem mass spectrometry analysis. Limits of detection for B. plantarii and tropolone were 10 colony-forming units (CFU)/mL and 0.017 MUg/kg, respectively. In a series of simulation trials, we found that B. plantarii from 10 to 108 CFU/mL produced tropolone between 0.006 and 107.8 mg/kg in a cell-population-dependent manner, regardless of habitat. Correlation analysis clarified a reliable reflection of B. plantarii density by tropolone level with R2 values from 0.9201 to 0.9756 ( p < 0.01). Through a nationwide pilot study conducted in China, tropolone contamination was observed at 0.014 0.157 mg/kg in paddy soil and rice grains, and subsequent redundancy analysis revealed soil organic matter to be a dominant environmental factor, having a positive correlation with tropolone contamination. In this context, our results imply that potential ecological and dietary risks posed by long-term exposure to trace levels of tropolone contamination are of concern. PMID- 29589437 TI - Atomic-Scale Simulation of Electrochemical Processes at Electrode/Water Interfaces under Referenced Bias Potential. AB - Based on constant Fermi-level molecular dynamics and a proper alignment scheme, we perform simulations of the Pt(111)/water interface under variable bias potential referenced to the standard hydrogen electrode (SHE). Our scheme yields a potential of zero charge MUpzc of ~0.22 eV relative to the SHE and a double layer capacitance Cdl of ?19 MUF cm-2, in excellent agreement with experimental measurements. In addition, we study the structural reorganization of the electrical double layer for bias potentials ranging from -0.92 eV to +0.44 eV and find that Odown configurations, which are dominant at potentials above the pzc, reorient to favor Hdown configurations as the measured potential becomes negative. Our modeling scheme allows one to not only access atomic-scale processes at metal/water interfaces, but also to quantitatively estimate macroscopic electrochemical quantities. PMID- 29589438 TI - Waterproof and Tailorable Elastic Rechargeable Yarn Zinc Ion Batteries by a Cross Linked Polyacrylamide Electrolyte. AB - Emerging research toward next-generation flexible and wearable electronics has stimulated the efforts to build highly wearable, durable, and deformable energy devices with excellent electrochemical performances. Here, we develop a high performance, waterproof, tailorable, and stretchable yarn zinc ion battery (ZIB) using double-helix yarn electrodes and a cross-linked polyacrylamide (PAM) electrolyte. Due to the high ionic conductivity of the PAM electrolyte and helix structured electrodes, the yarn ZIB delivers a high specific capacity and volumetric energy density (302.1 mAh g-1 and 53.8 mWh cm-3, respectively) as well as excellent cycling stability (98.5% capacity retention after 500 cycles). More importantly, the quasi-solid-state yarn ZIB also demonstrates superior knittability, good stretchability (up to 300% strain), and superior waterproof capability (high capacity retention of 96.5% after 12 h underwater operation). In addition, the long yarn ZIB can be tailored into short ones, and each part still functions well. Owing to its weavable and tailorable nature, a 1.1 m long yarn ZIB was cut into eight parts and woven into a textile that was used to power a long flexible belt embedded with 100 LEDs and a 100 cm2 flexible electroluminescent panel. PMID- 29589439 TI - Cost, Energy, and Environmental Impact of Automated Electric Taxi Fleets in Manhattan. AB - Shared automated electric vehicles (SAEVs) hold great promise for improving transportation access in urban centers while drastically reducing transportation related energy consumption and air pollution. Using taxi-trip data from New York City, we develop an agent-based model to predict the battery range and charging infrastructure requirements of a fleet of SAEVs operating on Manhattan Island. We also develop a model to estimate the cost and environmental impact of providing service and perform extensive sensitivity analysis to test the robustness of our predictions. We estimate that costs will be lowest with a battery range of 50-90 mi, with either 66 chargers per square mile, rated at 11 kW or 44 chargers per square mile, rated at 22 kW. We estimate that the cost of service provided by such an SAEV fleet will be $0.29-$0.61 per revenue mile, an order of magnitude lower than the cost of service of present-day Manhattan taxis and $0.05-$0.08/mi lower than that of an automated fleet composed of any currently available hybrid or internal combustion engine vehicle (ICEV). We estimate that such an SAEV fleet drawing power from the current NYC power grid would reduce GHG emissions by 73% and energy consumption by 58% compared to an automated fleet of ICEVs. PMID- 29589440 TI - Suppression of Auger Recombination in Nanocrystals via Ligand-Assisted Wave Function Engineering in Reciprocal Space. AB - A limiting factor to the technological application of conventional semiconductor nanostructures is their fast Auger recombination time. Strategies to increase it have so far mostly focused on decreasing the electron-hole wave function overlap in real space through structural modifications involving either elongation or shell growth. Here we propose an alternative mechanism for Auger recombination suppression: a decrease in the overlap of electron and hole wave functions in reciprocal space. PMID- 29589441 TI - Marbostat-100 Defines a New Class of Potent and Selective Antiinflammatory and Antirheumatic Histone Deacetylase 6 Inhibitors. AB - Epigenetic modifiers of the histone deacetylase (HDAC) family contribute to autoimmunity, cancer, HIV infection, inflammation, and neurodegeneration. Hence, histone deacetylase inhibitors (HDACi), which alter protein acetylation, gene expression patterns, and cell fate decisions, represent promising new drugs for the therapy of these diseases. Whereas pan-HDACi inhibit all 11 Zn2+-dependent histone deacetylases (HDACs) and cause a broad spectrum of side effects, specific inhibitors of histone deacetylase 6 (HDAC6i) are supposed to have less side effects. We present the synthesis and biological evaluation of Marbostats, novel HDAC6i that contain the hydroxamic acid moiety linked to tetrahydro-beta carboline derivatives. Our lead compound Marbostat-100 is a more potent and more selective HDAC6i than previously established well-characterized compounds in vitro as well as in cells. Moreover, Marbostat-100 is well tolerated by mice and effective against collagen type II induced arthritis. Thus, Marbostat-100 represents a most selective known HDAC6i and the possibility for clinical evaluation of a HDAC isoform-specific drug.

AB - A novel iodine-catalyzed amidation and imination at the 2alpha-position of 2,3 disubstituted indoles in the presence of chloramine salts with high regioselectivity has been achieved. The protocol is applicable to a wide range of substrates to deliver the corresponding 2alpha-nitrogen-containing indole derivatives.

PMID- 29589443 TI - Nanomolar-Potency 1,2,4-Triazoloquinoxaline Inhibitors of the Kidney Urea Transporter UT-A1. AB - Urea transporter A (UT-A) isoforms encoded by the Slc14a2 gene are expressed in kidney tubule epithelial cells, where they facilitate urinary concentration. UT A1 inhibition is predicted to produce a unique salt-sparing diuretic action in edema and hyponatremia. Here we report the discovery of 1,2,4 triazoloquinoxalines and the analysis of 37 synthesized analogues. The most potent compound, 8ay, containing 1,2,4-triazolo[4,3- a]quinoxaline-substituted benzenesulfonamide linked by an aryl ether, rapidly and reversibly inhibited UT A1 urea transport by a noncompetitive mechanism with IC50 ~ 150 nM; the IC50 was ~2 MUM for the related urea transporter UT-B encoded by the Slc14a1 gene. Molecular modeling suggested a putative binding site on the UT-A1 cytoplasmic domain. In vitro metabolism showing quinoxaline ring oxidation prompted the synthesis of metabolically stable 7,8-difluoroquinoxaline analogue 8bl, which when administered to rats produced marked diuresis and reduced urinary osmolality. 8bl has substantially improved UT-A1 inhibition potency and metabolic stability compared with prior compounds. PMID- 29589444 TI - Actinium Hydrides AcH10, AcH12, and AcH16 as High-Temperature Conventional Superconductors. AB - The stability of numerous unexpected actinium hydrides was predicted via the evolutionary algorithm USPEX. The electron-phonon interaction was investigated for the hydrogen-richest and most symmetric phases: R3 m-AcH10, I4/ mmm-AcH12, and P6 m2-AcH16. Predicted structures of actinium hydrides are consistent with all previously studied Ac-H phases and demonstrate phonon-mediated high temperature superconductivity with TC in the range of 204-251 K for R3 m-AcH10 at 200 GPa and 199-241 K for P6 m2-AcH16 at 150 GPa, which was estimated by directly solving the Eliashberg equation. Actinium belongs to the series of d1 elements (Sc-Y-La-Ac) that form high- TC superconducting (HTSC) hydrides. Combining this observation with previous predictions of p0-HTSC hydrides (MgH6 and CaH6), we propose that p0 and d1 metals with low-lying empty orbitals tend to form phonon mediated HTSC metal polyhydrides.

AB - In the present article, the M1 mAChR bitopic agonist 1-[3-(4-butylpiperidin-1 yl)propyl]-1,2,3,4-tetrahydroquinolin-2-one (77-LH-28-1, 1) has been demonstrated to show unexpected D4R selectivity over D2R and D3R and to behave as a D4R antagonist. To better understand the structural features required for the selective interaction with the D4R and to obtain compounds unable to activate mAChRs, the aliphatic butyl chain and the piperidine nucleus of 1 were modified, affording compounds 2-14. The 4-benzylpiperidine 9 and the 4-phenylpiperazine 12 showed high D4R affinity and selectivity not only over the other D2-like subtypes, but also over M1-M5 mAChRs. Derivative 12 was also highly selective over some selected off-targets. This compound showed biased behavior, potently and partially activating Gi protein and inhibiting beta-arrestin2 recruitment in functional studies. Pharmacokinetic studies demonstrated that it was characterized by a relevant brain penetration. Therefore, 12 might be a useful tool to better clarify the role played by D4R in disorders in which this subtype is involved.

AB - Detection of bacterial metabolites at low concentrations in fluids with complex background allows for applications ranging from detecting biomarkers of respiratory infections to identifying contaminated medical instruments. Surface enhanced Raman scattering (SERS) spectroscopy, when utilizing plasmonic nanogaps, has the relatively unique capacity to reach trace molecular detection limits in a label-free format, yet large-area device fabrication incorporating nanogaps with this level of performance has proven difficult. Here, we demonstrate the advantages of using chemical assembly to fabricate SERS surfaces with controlled nanometer gap spacings between plasmonic nanospheres. Control of nanogap spacings via the length of the chemical crosslinker provides uniform SERS signals, exhibiting detection of pyocyanin, a secondary metabolite of Pseudomonas aeruginosa, in aqueous media at concentration of 100 pg.mL-1. When using machine learning algorithms to analyze the SERS data of the conditioned medium from a bacterial culture, having a more complex background, we achieve 1 ng.mL-1 limit of detection of pyocyanin and robust quantification of concentration spanning 5 orders of magnitude. Nanogaps are also incorporated in an in-line microfluidic device, enabling longitudinal monitoring of P. aeruginosa biofilm formation via rapid pyocyanin detection in a medium effluent as early as 3 h after inoculation and quantification in under 9 h. Surface-attached bacteria exposed to a bactericidal antibiotic were differentially less susceptible after 10 h of growth, indicating that these devices may be useful for early intervention of bacterial infections.

AB - The performance of an organic semiconductor device is critically determined by the geometric alignment, orientation, and ordering of the organic molecules. Although an organic multilayer eventually adopts the crystal structure of the organic material, the alignment and configuration at the interface with the substrate/electrode material are essential for charge injection into the organic layer. This work focuses on the prototypical organic semiconductor para sexiphenyl (6P) adsorbed on In2O3(111), the thermodynamically most stable surface of the material that the most common transparent conducting oxide, indium tin oxide, is based on. The onset of nucleation and formation of the first monolayer are followed with atomically resolved scanning tunneling microscopy and noncontact atomic force microscopy (nc-AFM). Annealing to 200 degrees C provides sufficient thermal energy for the molecules to orient themselves along the high symmetry directions of the surface, leading to a single adsorption site. The AFM data suggests an essentially planar adsorption geometry. With increasing coverage, the 6P molecules first form a loose network with a poor long-range order. Eventually, the molecules reorient into an ordered monolayer. This first monolayer has a densely packed, well-ordered (2 * 1) structure with one 6P per In2O3(111) substrate unit cell, that is, a molecular density of 5.64 * 1013 cm-2.

AB - The electronic structure of multiexcitons significantly impacts the performance of nanostructures in lasing and light-emitting applications. However, these multiexcitons remain poorly understood due to their complexity arising from many body physics. Standard transient-absorption and photoluminescence spectroscopies are unable to unambiguously distinguish effects of sample inhomogeneity from exciton-biexciton interactions. Here, we exploit the energy and time resolution of two-dimensional electronic spectroscopy to access the electronic structure of the band-edge biexciton in colloidal CdSe quantum dots. By removing effects of inhomogeneities, we show that the band-edge biexciton structure must consist of a discrete manifold of electronic states. Furthermore, the biexciton states within the manifold feature distinctive binding energies. Our findings have direct implications for optical gain thresholds and efficiency droop in light-emitting devices and provide experimental measures of many-body physics in nanostructures.

AB - We demonstrate a facile method to improve upconversion quantum yields in Yb,Er based nanoparticles via emission dye-sensitization. Using the commercially available dye ATTO 542, chosen for its high radiative rate and significant spectral overlap with the green emission of Er3+, we decorate the surfaces of sub 25 nm hexagonal-phase Na(Y/Gd/Lu)0.8F4:Yb0.18Er0.02 upconverting nanoparticles with varying dye concentrations. Upconversion photoluminescence and absorption spectroscopy provide experimental confirmation of energy transfer to and emission from the dye molecules. Upconversion quantum yield is observed to increase with dye sensitization, with the highest enhancement measured for the smallest particles investigated (10.9 nm in diameter); specifically, these dye-decorated particles are more than 2* brighter than are unmodified, organic-soluble nanoparticles and more than 10* brighter than are water-soluble nanoparticles. We also observe 3* lifetime reductions with dye adsorption, confirming the quantum yield enhancement to result from the high radiative rate of the dye. The approach detailed in this work is widely implementable, renders the nanoparticles water soluble, and most significantly improves sub-15 nm nanoparticles, making our method especially attractive for biological imaging applications. PMID- 29589450 TI - Spiro-Conjugated Molecular Junctions: Between Jahn-Teller Distortion and Destructive Quantum Interference. AB - The quest for molecular structures exhibiting strong quantum interference effects in the transport setting has long been on the forefront of chemical research. We establish theoretically that the unusual geometry of spiro-conjugated systems gives rise to complete destructive interference in the resonant-transport regime. This results in a current blockade of the type not present in meta-connected benzene or similar molecular structures. We further show that these systems can undergo a transport-driven Jahn-Teller distortion, which can lift the aforementioned destructive-interference effects. The overall transport characteristics are determined by the interplay between the two phenomena. Spiro conjugated systems may therefore serve as a novel platform for investigations of quantum interference and vibronic effects in the charge-transport setting. The potential to control quantum interference in these systems can also turn them into attractive components in designing functional molecular circuits.

AB - INTRODUCTION: Gastroschisis is the most common malformation among abdominal wall defects with the incidence of 1:45000 live birth neonates. Postoperative care for these patients is very difficult due to the risk of abdominal compartment syndrome. The identification of markers that correlate with bowel damage in gastroschisis may prevent this serious postoperative complication. METHODS: Review of the literature. CONCLUSION: Prenatal ultrasound prediction of bowel damage followed by an appropriate surgical strategy is a possibility of optimizing care and outcomes in gastroschisis patients. The dynamics of I-FABP is a promising biomarker for the elimination of abdominal compartment syndrome during postoperative care.Key words: gastroschisis preformed silo intraabdominal dilatation I-FABP. PMID- 29589451 TI - Reliable Strategy for Analysis of Complex Biosensor Data. AB - When using biosensors, analyte biomolecules of several different concentrations are percolated over a chip with immobilized ligand molecules that form complexes with analytes. However, in many cases of biological interest, e.g., in antibody interactions, complex formation steady-state is not reached. The data measured are so-called sensorgram, one for each analyte concentration, with total complex concentration vs time. Here we present a new four-step strategy for more reliable processing of this complex kinetic binding data and compare it with the standard global fitting procedure. In our strategy, we first calculate a dissociation graph to reveal if there are any heterogeneous interactions. Thereafter, a new numerical algorithm, AIDA, is used to get the number of different complex formation reactions for each analyte concentration level. This information is then used to estimate the corresponding complex formation rate constants by fitting to the measured sensorgram one by one. Finally, all estimated rate constants are plotted and clustered, where each cluster represents a complex formation. Synthetic and experimental data obtained from three different QCM biosensor experimental systems having fast (close to steady-state), moderate, and slow kinetics (far from steady-state) were evaluated using the four-step strategy and standard global fitting. The new strategy allowed us to more reliably estimate the number of different complex formations, especially for cases of complex and slow dissociation kinetics. Moreover, the new strategy proved to be more robust as it enables one to handle system drift, i.e., data from biosensor chips that deteriorate over time.

AB - INTRODUCTION: Surgical diseases of the pancreas in children are not common and may be associated with significant morbidity and potential mortality. A multidisciplinary approach is essential for correct diagnosis, surgical strategy and postoperative as well as follow-up care. METHOD: Retrospective analysis of patients operated on due to a pathological lesion of the pancreas focused on diagnostics, operating procedures, postoperative complications, and long-term results. Between 1991 and 2016, eighty-nine children were treated in our department for a pathologic lesion of the pancreas. 39 of them were boys and 50 were girls. RESULTS: Mean age of the patients was 9.3 years (1 month-18.4 years). Patients were followed from the operation to the age of 19, after which they were referred for follow-up to adult specialists. The indications for surgery were trauma in 34 children, solid pseudopapillary tumor in 23 children, biopsy in 10, hyperinsulinism in 8, chronic pancreatitis in 4, pancreatic cyst in 3, insulinoma in 3, carcinoma in 2, and serous cystadenoma and pancreas divisum in one patient. The most frequent procedures performed on the pancreas were distal pancreatectomy in 35 cases, the duodenum-preserving pancreatic head resection in 23 cases, pseudocystogastroanastomosis in 11 cases, 9095% pancreatic resection in 5 cases, Whipple operation in two cases, Puestow procedure in one case, tumor enucleation in one case, and tumor biopsy for cancer in one case. In 5 patients after major pancreatic injury, ERCP and papillotomy with insertion of a stent into the pancreatic duct was performed. 3 patients died, one after a polytrauma with severe pancreatic injury and two patients with pancreatic cancer. CONCLUSION: Pancreatic surgery in children is not a common operation, and individual as well as institutional experience remains limited. After more than 20 years of experience with pancreatic surgery, we believe that close cooperation with surgeons, pediatric gastroenterologists, radiologists, anesthesiologists, intensivist, pathologists and ERCP specialists is necessary for successful diagnosis and treatment of pancreatic disease in children.Key words: pancreas pancreatic surgery in children duodenum preserving head resection of the pancreas.

The basic therapeutic procedure is an appendectomy. Open appendectomy has been gradually supplemented and sometimes replaced by a laparoscopic approach in numerous departments. The aim of our work was to compare laparoscopic and open surgery objectively. METHOD: Retrospective analysis of data from patients operated on at the Department of Pediatric Surgery and Traumatology, Teaching Hospital in Hradec Kralove in 20092016. Only the precisely evaluated parameters, i.e. the time of anesthesia, the time of surgery and the duration of post operative pain, were assessed within the scope of objectification. Data were evaluated only in a homogeneous group of patients with phlegmonous appendicitis. RESULTS: During the above period, 261 patients with acute appendicitis were operated on at our department, 166 of whom suffered from phlegmonous appendicitis. 133 children were operated laparoscopically and 33 by open procedure. The results obtained were statistically significantly different only for the time of anesthesia (p=0.00035) which was shorter in open operations. The time of surgery was also shorter in the open operation group, but only at the limit of statistical significance. A statistically significant difference was not found in the time of duration of pain for individual surgical approaches. CONCLUSION: Laparoscopic approach in the surgical treatment of acute appendicitis is a more modern method than open surgery and it has become a standard procedure in some departments. However, the results of our study confirm that the open approach remains an equivalent alternative to the treatment of acute phlegmonous appendicitis.Key words: appendicitis open appendectomy laparoscopy.

Problems with its diagnostics and treatment as well as its complications and sequels have not been fully solved yet. That is evidenced by a large amount of articles with frequently inconsistent conclusions. The aim is to evaluate contemporary diagnostic and therapeutic approach based on our own clinical experience. METHODS: A total of 2847 children with skeletal injury were treated by the authors during the year 2016. Two hundred and seventy five of them suffered from supracondylar fracture of the humerus (9.66%). All the fractures were classified using the authors own scheme. Fragment displacement was evaluated according to a three-degree scale. RESULTS: Ninety-three of 275 supracondylar fractures were treated non-operatively (33.8%) and 182 by surgery (66.2%). Closed reduction and percutaneous pinning by K-wires under X-ray (C-arm) control was the method of choice. Crossed K-wires were used in 90% and in 9.9% two K-wires were inserted laterally only. In 70.9%, pins were buried and in 29.1 % unburied pins were used. Neurological lesions were noted in 13.5%. A total of 82.9% of children were healed without any sequels. CONCLUSION: Supracondylar fracture of the humerus in children should be managed in pediatric trauma centers, especially in more complicated cases. Fracture classification needs to be more detailed than those commonly used so far. Closed reduction and percutaneous pinning is the method of choice. Acute neurological and/or vascular complications can be managed in an overwhelming majority of cases, after fragment fixation, non-surgically.Key words: supracondylar fracture humerus, miniinvasive osteosynthesis neural lesion compartment syndrome.

AB - INTRODUCTION: Laparoscopy in small children was developed only after the adoption and verification of basic principles in adult patients and is mostly concentrated in specialized facilities due to the possible complications and necessity of follow-up specialized anesthesiological and post-operative care. In the 1990s, the Clinic of Paediatric Surgery, Orthopaedics and Traumatology at University Hospital Brno was one of the first in the Czech Republic to begin operating on children laparoscopically. The presented study informs about the development of these minimally invasive methods, the frequency of their use, and the spectrum of patients at the pediatric surgery facility where laparoscopy in children has been systematically developed over many years. METHODS: Retrospective analysis of children operated upon laparoscopically at the clinic of Paediatric surgery, Orthopaedics and Traumatology of University Hospital Brno over the five-year period from 1 January 2012 to 31 December 2016. A list of surgical procedures was prepared which was then first divided into procedures specific exclusively for children and those common to adult patients surgery. Separately, an overview was prepared of operated patients under 50 kg, which was the boundary criterion defined by the authors for laparoscopy in children as opposed to adults. For all procedures, the frequency of the completed cases performed laparoscopically was precisely ascertained. The source for this data was the hospital system and surgical documentation. RESULTS: In the evaluated period, a total of 995 laparoscopic procedures were performed, more than half of which (56.8%) were in patients under 50 kg. The majority of those were procedures performed also in adults. The group of surgical operations exclusively specific to children was characterized by low frequencies of the individual procedures. CONCLUSION: The presented analysis confirms that laparoscopy in children is based on standard procedures common to surgery on adults. These procedures are adopted the most quickly, and they can be disseminated across a large group of surgeons who are then able to perform these routinely on child patients. Surgical procedures exclusively specific for children, on the other hand, are performed less frequently, their adoption is slower, and laparoscopic approach is less common. Therefore, laparoscopy specific to children needs to be performed on a long-term basis, systematically, and within a small group of surgeons. Otherwise, it is better not to perform it at all.Key words: laparoscopy - child frequency. PMID- 29589457 TI - [Hirschsprungs disease in adults two case reports and review of the literature]. AB - Hirschsprungs disease (HD) in adults is extremely rare, only three publications in Czech and Czechoslovak journals making reference to the condition after childhood. We present two cases of adult patients with HD. The first case is a 46 year-old male patient suffering from chronic constipation since childhood and diagnosed with megacolon at the age of 16; however, no further detailed diagnosis was done. At the age of 41, he developed a sigmoid perforation due to fecaloma and underwent urgent rectosigmoid resection and colostomy. 5 months later, Swensons coloanal anastomosis with diverting ileostomy was performed. Postoperative course was uneventful. He has two bowel movements a day. 7 years after the Swensons procedure, he also underwent adhesiolysis for acute bowel obstruction. His daughter was operated on due to HD at 16 days of age. The second case is a 57-year-old male patient. He suffered from chronic constipation and megacolon since 2 years of age and was diagnosed with congenital megacolon at the age of 19. However, no detailed diagnostics followed. He had a long interval between stools of up to 14 days. He underwent colonoscopy and, with a diagnosis of resistant Crohns disease, was referred to a surgical department where he was diagnosed with HD. Left hemicolectomy was first performed, followed by Swensons procedure with diverting ileostomy. All postoperative courses were uneventful. Currently he passes one or two soft stools a day. Adult HD is extremely rare. However, adult surgeons should consider it in case of refractory constipation since childhood associated with megacolon. Diagnosis is based on contrast radiography and rectal biopsy. Both Swensons and Duhamels procedures are suitable for surgical management. Left hemicolectomy with colonic rotation and coloanal anastomosis and/or proctocolectomy with J-pouch anastomosis are indicated in advanced forms of non-functional megacolon.Key words: adult Hirschsprungs disease - megacolon surgical therapy. PMID- 29589458 TI - Laparoscopic treatment of bowel perforation after blunt abdominal trauma (BAT) in children. AB - Minimally invasive techniques have now become standard for the treatment of many surgical conditions in children. There are a few studies that describe the utility of laparoscopy in BAT in children. In this article, we describe the complete laparoscopic surgical treatment of two patients after a single blunt abdominal trauma, both with bowel perforation. In both cases, the perforation was identified and closed, one laparoscopically with an ongoing suture, the second jejune perforation was closed by laparoscopic-assisted techniques. Both patients had an uneventful postoperative recovery. Therapeutic laparoscopic treatment of patients with upper gastrointestinal perforation is feasible. We hypothesize, that diagnostic laparoscopy provides important information for the treatment of children with abdominal trauma and is accompanied by improved diagnostic accuracy, reduction of nontherapeutic laparotomy rates, and a reduction of morbidity. Minimally invasive surgery in children after BAT is suitable for hemodynamic stable patients, could improve pain scores, cosmetic effect, shorter hospital stays, shorter operative times and shorter return to school/activities. However, at any point in the patients care, in case the unstable hemodynamic is encountered, exploratory laparotomy is the procedure of choice.Key words: miniinvasive surgery blunt abdominal trauma - laparoscopy bowel perforation.

AB - Aim of the study was to evaluate retrospectively selected parameters, which influence the postoperative near visual acuity in a group of pseudophakic eyes of patients with Uncorrected Distance Visual Acuity (UDVA) and according to acquired results establish those, which mostly influenced good Uncorrected Near Visual Acuity (UNVA) after the implantation of monofocal IntraOcular Lens (IOL). Altogether, 122 pseudophakic eyes of 65patients were followed up, out of them in 57 patients both eyes were operated on. The frequency of visual acuity for three groups of operated eyes categorized according to the crucial parameter - eyes axial length (short, average, long) was evaluated. In each of groups, the average parameters (age, axial length, keratometry, and depth of the anterior chamber) were established, as well as relative frequency of postoperative uncorrected near visual acuity on conventionally used reading tables. The near visual acuity assessment for each eye separately was preformed in its horizontal position using the Zeiss table. The study did not confirm positive correlation of postoperative near visual acuity on the age of the patient, depth of the anterior chamber, nor the implanted IOL type. It was confirmed the presumption of optimal near visual acuity for eyes with axial length shorter than 23.5 mm, and in the process, between both parameters slightly negative correlation was found. On the other hand, middle positive correlation between uncorrected near visual acuity and central corneal power (in dioptres) in eyes with the axial length 22.5 - 23.5 mm was found. The study confirmed, that higher values of the central corneal power (in dioptres) and the high borderline value of the axial length up to 23.5 mm are the condition for optimal postoperative uncorrected near visual acuity after the implantation of monofocal intraocular lens.Key words: Uncorrected Near Visual Acuity (UNVA), monofocal intraocular lens, pseudoaccommodation.

AB - INTRODUCTION: The aim of this work is to evaluate our own results of surgical treatment of retinal detachment in immature newborns. Retinopathy of prematurity (ROP) is one of the most complicated ocular disorders, both in terms of diagnosis and therapy. It is a potentially blinding illness that arises from the incomplete development of the bloodstream of the neuroretina of preterm infants. Currently, the most effective therapy is ablation of the avascular retina by laser photocoagulation or cryocoagulation. Despite this treatment, the immature retina may develop it's detachment. METHODOLOGY: We report 2 case-reports, retrospective results of 4-eyes in 2 patients with severe ocular and overall complications of prematurity. The ocular background of preterm babies was investigated in arteficial mydriasis by an indirect ophthalmoscope, and later with the RetCam photographic device. The ROP stages were evaluated according to the ICROP classification. All eyes were treated with cryo-retinopexy at the threshold stage of ROP, followed by intraocular surgery for progression of traction retinal detachment. The surgical technique was a 3-port 25-G PPV (pars-plicata vitrectomy) with insertion of ports 1.5 mm from limbus. The PPV was performed using the Constellation (ALCON) operating unit, controlling the intraocular pressure for 15 torr. The assessment of visual acuity was performed according to the scale: no light perception (no response of the child to light), light sensitivity (positive or negative reaction to illumination), fixation of light. RESULTS: The retina stayed attached in all operated eyes, more in each case report. CONCLUSION: Contemporary vitreoretinal surgery allows for the anatomical success of traction retinal detachment surgery during ROP already in neonatal age.Key words: retinal detachment, retinopathy of prematurity, PPV, surgery.

Author proves photographs preparing expander own design and modified surgical technique. It was also operated on 10 patients for accompanying Y-exotropia. Eleven patients with acute form of Brown's syndrome in the pulley of upper oblique muscle applied Betamethasoni. RESULTS: The using expander own design - non-resorbable Ethibond 5-0 cauted silicone cannula - held at congenital form of Browns syndrome, without a weighty complication or its exclusion in the period. The result of the performance was determined age of patients at the time of implantation of the expander. Preschoolers postoperative condition was fully compliant, this expander standardized vertical mobility. The vertical alignment motility is reduced with advancing age, especially in adulthood. Optimal surgical procedures at Y exotropia were antepozice with recession of the inferior oblique muscle possibly supplemented by retroposition ipsilateral external rectus. The application efficiency of Betamethasoni for acute form of Brown's syndrome in the pulley of upper oblique muscle was successful in only two weeks after the initial symptoms vertical diplopia. CONCLUSION: Expander own design which represented non resorbable Ethibond cauted silicone cannula was very effective in dealing with congenital form of Browns syndrome. The application of glucocorticoids in the pulley of upper oblique muscle should always be a quantity result.Key words: Browns syndrome, Betamethasoni, expander, Ethibond, silicone cannula, Y - exotropia.

It provides serial images of a face optical sections through the full-thickness of the living cornea, avoiding artefacts associated with ex vivo study. It provides qualitative as well as quantitative analysis of the corneal layers, nerves, and cells. It also allows longitudinal examination of the corneal structure changes over time.

AB - In vivo corneal confocal microscopy (CCM) represents a new, non-invasive, rapidly developing corneal examination technique that enables individual layers of the cornea to be displayed at the cellular level. The cornea is the translucent and at the same time the most innervated tissue of the human body. Diabetic neuropathy (DN) is a serious complication of diabetes mellitus (DM). A close correlation has been demonstrated between the development of diabetic neuropathy and the pathological changes of the corneal subbasal plexus. Currently, great attention is directed towards the possibility of using CCM to determine early DN. Interestingly, changes in nerve plexus in the cornea precede the clinical manifestations of DN. Our work aims to give a comprehensive overview of the current possibilities and trends in use of in vivo CCM in connection with DN evaluation. In vivo CCM becomes important in the search for patients at risk of developing DN, in early diagnosis of DN in pre-symptomatology, in quantifying severe DN, in monitoring and evaluating the therapeutic response to DM treatment. In addition to its diagnostic and preventive significance, it is a research tool important for understanding the pathophysiology of DM changes.Key words: confocal microscopy, cornea, small fibre neuropathy, diabetes mellitus, diabetic neuropathy.

The epidemic of human immunodeficiency virus type 1 (HIV-1) infection is gradually increasing in this region. We collected peripheral blood samples from 62 antiretroviral therapy experienced individuals. The amplification of viral genomic fragments, HIV-1 subtyping, and the detection of HIV drug resistance (HIVDR) were performed. Viral subtyping revealed that the most prevalent HIV-1 subtype/circulating recombinant form (CRF) was CRF01_AE (55.6%), followed by recombinants between CRF01_AE and subtype B (17.8%) and then subtype B (15.6%). Recombinants containing CRF02_AG gene fragments were also detected (11.1%). Regarding HIVDR, no drug resistance associated major mutations were found in pol genes encoding protease, although minor mutations were frequently detected. Furthermore, major mutations, including M184V (2.2%) and Y188L (2.2%), were identified in the viral pol gene encoding reverse transcriptase derived from a study participant, suggesting that the prevalence of HIVDR is low in the region. PMID- 29589466 TI - A systematic review of epidemiologic studies of styrene and cancer. AB - Previous epidemiology reviews of exposure to styrene and the risk of cancer considered studies published through 13 November 2013. Since then, additional relevant research has been published. No review has included meta-analyses. The current systematic review considered research published through June 2017; included meta-analyses of the relationship between any exposure to styrene and cancers identified as being of concern, including non-Hodgkin lymphoma (NHL), leukemia and cancers of the esophagus, pancreas, lung and kidney; and evaluated several other forms of cancer. Meta-relative risks for all studies were 1.14 (95% confidence interval (CI), 0.91-1.43) for NHL, 1.00 (95% CI, 0.80-1.26) for multiple myeloma, 0.98 (95% CI, 0.87-1.09) for all leukemia, 1.03 (95% CI, 0.92 1.15) for esophageal cancer, 1.02 (95% CI, 0.93-1.12) for pancreatic cancer, 1.09 (95% CI, 0.95-1.24) for lung cancer and 1.10 (95% CI, 0.99-1.22) for kidney cancer. Individual studies provided little evidence of exposure-response or induction time trends. Limitations of the available research and of the meta analyses included reliance in most studies on mortality data rather than on incidence data, lack of quantitative estimates of styrene exposure for individual subjects and lack of information on lifestyle factors. Consideration of all pertinent data, including substantial recent research, indicates that the epidemiologic evidence on the potential carcinogenicity of styrene is inconclusive and does not establish that styrene causes any form of cancer in humans. PMID- 29589467 TI - Meta-analysis of individual registry results enhances international registry collaboration. AB - Background and purpose - Although common in medical research, meta-analysis has not been widely adopted in registry collaborations. A meta-analytic approach in which each registry conducts a standardized analysis on its own data followed by a meta-analysis to calculate a weighted average of the estimates allows collaboration without sharing patient-level data. The value of meta-analysis as an alternative to individual patient data analysis is illustrated in this study by comparing the risk of revision of porous tantalum cups versus other uncemented cups in primary total hip arthroplasties from Sweden, Australia, and a US registry (2003-2015). Patients and methods - For both individual patient data analysis and meta-analysis approaches a Cox proportional hazard model was fit for time to revision, comparing porous tantalum (n = 23,201) with other uncemented cups (n = 128,321). Covariates included age, sex, diagnosis, head size, and stem fixation. In the meta-analysis approach, treatment effect size (i.e., Cox model hazard ratio) was calculated within each registry and a weighted average for the individual registries' estimates was calculated. Results - Patient-level data analysis and meta-analytic approaches yielded the same results with the porous tantalum cups having a higher risk of revision than other uncemented cups (HR (95% CI) 1.6 (1.4-1.7) and HR (95% CI) 1.5 (1.4-1.7), respectively). Adding the US cohort to the meta-analysis led to greater generalizability, increased precision of the treatment effect, and similar findings (HR (95% CI) 1.6 (1.4 1.7)) with increased risk of porous tantalum cups. Interpretation - The meta analytic technique is a viable option to address privacy, security, and data ownership concerns allowing more expansive registry collaboration, greater generalizability, and increased precision of treatment effects.

PMID- 29589469 TI - Assessing speech, language and communication difficulties in children referred for ADHD: A qualitative evaluation of a UK child and adolescent mental health service. AB - BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) is one of the most common childhood neuropsychiatric disorders and is highly comorbid with speech, language and communication difficulties (SLCDs). However, it is unclear how often SLCDs are identified in ADHD referrals in routine practice and whether there are unidentified SLCDs within this population. METHOD: A thematic analysis was conducted on a random sample of case notes from 18 referrals for ADHD made to a child and adolescent mental health service (CAMHS) in London, United Kingdom. Analyses aimed to identify (a) the types of SLCDs detected during assessment, (b) at which point of the episode of care these SLCDs were suspected and (c) whether a referral or consultation was made to a speech and language therapist (SLT) for further evaluation. RESULTS: Out of 18 cases investigated, 15 were found to have possible SLCDs based on case notes and reports provided by external agencies. However, only four were referred by CAMHS for further assessment. It is unclear what, if any, steps other external agencies took. Themes describing types of SLCDs, comorbidities and the process of identification are discussed. CONCLUSION: The analysis of this service's case notes revealed a range of different routes to the identification of SLCDs, and it was unclear what steps were taken as a result of assessment. A limitation is that this is just one service and the results may not generalise. However, given the similarity in practitioner training received across the country and that practitioners move from service to service, there are grounds for repeating the study in other services. We recommend a more structured approach to identifying SLCDs and recording assessment and treatment decisions made. PMID- 29589470 TI - The merit of tyrosine kinase inhibitors in the adjuvant setting of high-risk renal cell carcinoma: a meta-analysis. AB - AIM: As no meta-analyses have evaluated tyrosine kinase inhibitors in the adjuvant setting of high-risk renal cell carcinoma (RCC), the aim was to evaluate the benefit of sunitinib and pazopanib in the adjuvant setting. METHODS: This meta-analysis included all Phase III randomized controlled trials evaluating adjuvant sunitinib and pazopanib in high-risk RCC. Primary outcome was the comparison of disease-free survival (DFS) between tyrosine kinase inhibitors and placebo. RESULTS: There was a tendency for significant overall effect of both sunitinib and pazopanib on DFS (hazard ratio: 0.85; 95% confidence interval: 0.72 1.01; p = 0.06). There was no significant difference between the effect of sunitinib and pazopanib on DFS (p = 0.51; I2 = 0%). CONCLUSION: Pazopanib and sunitinib could prolong DFS in the adjuvant treatment of high-risk RCC and seem equally effective in this setting. PMID- 29589471 TI - De-escalating treatment in the adjuvant setting in HER2-positive breast cancer. AB - The decision to offer adjuvant therapy to patients with early-stage cancer relies on factors related to the risk of disease recurrence, degree of benefit with the proposed therapy and the associated risk of toxicities. For patients with stages II and III HER2-positive breast cancer, administering 1 year of trastuzumab plus comprehensive chemotherapy is the standard of care. However, the pivotal adjuvant trials had very few older patients and patients with small HER2-positive tumors. In this review, we will discuss the clinical data regarding strategies to de escalate adjuvant systemic therapy in patients with early stage HER2-positive disease. PMID- 29589472 TI - Anti-inflammatory and antiproliferative prenylated chalcones from Hedysarum gmelinii. AB - Five new prenylated chalcones hedysarumines C-G (1-5), along with eight known chalcones (6-13) all of which were isolated from the genus Hedysarum for the first time, were isolated from the roots of Hedysarum gmelinii by chromatographic methods. Their structures were determined by extensive spectroscopic techniques. The isolated chalcones (2-13) and previously isolated prenylated chalcones (14 16) were evaluated for antiproliferative activity against five human cancer cell lines (HepG2, A549, Du145, BGC823, and HCT116) and in vitro anti-inflammatory activity. Compounds 5, 10, and 15 inhibited NO production induced by lipopolysaccharide in BV-2 cells, with IC50 values ranging from 3.25 to 8.48 MUM. Compounds 4 and 11 showed moderate antiproliferative activity to selective human cancer cell lines, with the IC50 values of 4 and 11 against A549 cell line being 7.79 and 9.67 MUM, respectively, and the IC50 value of 11 against HCT116 cell line being 8.85 MUM. PMID- 29589473 TI - Evaluation of Point-of-Care Resources for Dietary Supplement Information. AB - OBJECTIVE: To evaluate 6 tertiary, point-of-care drug information resources' dietary supplement content. METHODS: This was a cross-sectional evaluation of Lexicomp Natural Products Database, Micromedex Alternative Medicine, Clinical Pharmacology, Natural Medicines, The Review of Natural Products, and Handbook of Nonprescription Drugs. Each resource was evaluated for scope, completeness, consistency, and ease of use. RESULTS: For a sample of 66 supplements, scope scores ranged from 69.7% (Micromedex) to 100% (Natural Medicines). Completeness scores were high considering uses, dose, adverse effects, and mechanism (85.7% to 100%). Overall completeness scores ranged from 82.5% ( Handbook of Nonprescription Drugs) to 100% (Clinical Pharmacology, Natural Medicines, The Review of Natural Products). Consistency scores ranged from 0% ( Handbook of Nonprescription Drugs) to 100% (Natural Medicines, The Review of Natural Products). Mean time to locate and gather information was similar among groups. CONCLUSIONS: Resources were similar for completeness and ease of use. Scope and consistency varied depending on the resource. PMID- 29589474 TI - What influences decisions about ongoing stroke rehabilitation for patients with pre-existing dementia or cognitive impairment: a qualitative study? AB - OBJECTIVE: To identify factors influencing clinicians decision-making about ongoing stroke rehabilitation for people with pre-existing dementia/cognitive impairment and the impact on clinical practice. DESIGN: Qualitative semi structured interviews with stroke specialist healthcare professionals analysed using thematic analysis. SETTING: Acute stroke unit, inpatient stroke rehabilitation units, and community stroke services. PARTICIPANTS: Twenty three professionals from six multidisciplinary stroke teams involved in decision-making about stroke patients' rehabilitation potential and clinical pathways. RESULTS: Factors influencing decision-making about ongoing rehabilitation were (1) gaining understanding of the individual patient, (2) clinician's knowledge of dementia/cognitive impairment, (3) predicting rehabilitation potential, (4) organizational constraints, and (5) clinician's perceptions of their role within the team. Decision-making led to two outcomes, either accommodating the pre existing dementia/cognitive impairment within delivery of rehabilitation or ending rehabilitation for that patient to allocate limited resources where they were perceived more likely to be effective. Participants felt that patients with pre-existing dementia/cognitive impairment had difficulty demonstrating the required rehabilitation potential within the short timescales available in the current model of service delivery. Participants identified a need for training to improve their knowledge and confidence for decision-making and delivery of rehabilitation for this growing population. CONCLUSION: Clinicians' decision making about ongoing rehabilitation for patients with prestroke dementia/cognitive impairments is influenced by gaps in their knowledge and by service constraints. Increased training and more flexible, patient-centred services would enable clinicians to better accommodate these patients in rehabilitation. PMID- 29589475 TI - Analysis of indirect treatment comparisons in national health technology assessment assessments and requirements for industry submissions. AB - AIM: To determine the preferred methodologies of health technology assessment (HTA) agencies across Europe, Canada and Australia to ascertain acceptance of indirect treatment comparisons (ITC) as a source of comparative evidence. METHOD: A review of official submission guidelines and analysis of comments in HTA submissions that have used different ITC methodologies. CONCLUSION: ITC is generally accepted as a technique that allows demonstration of noninferiority to a comparator provided the chosen methodology and underlying assumptions are clear and justified. However, HTA agencies are more likely to closely scrutinize submitted data and evaluate statistical significance of results when superiority is claimed. In addition, the HTA agencies in scope tended to be cautious and only accept ITC data as support for similarity of treatments. PMID- 29589476 TI - Antibacterial activities of a series of novel 5-O-(4', 6'-O-dimodified) mycaminose 14-membered ketolides. AB - A series of novel 5-O-(4',6'-O-dimodified)-mycaminose 14-membered ketolides were assessed for their in vitro antibacterial activities against a panel of sensitive and resistant pathogens. Compound 1 and compound 2, two ester analogs, showed the best antibacterial activities against several macrolide-sensitive and macrolide resistant strains. These results indicated that introducing ester to 6-OH and a small volume ether substituent to the 4-OH of mycaminose could improve the antibacterial activities of ketolides. PMID- 29589477 TI - Drug repositioning for novel antitrichomonas from known antiprotozoan drugs using hierarchical screening. AB - AIM: Metronidazole is the most widely used drug in trichomoniasis therapy. However, the emergence of metronidazole-resistant Trichomonas vaginalis isolates calls for the search for new drugs to counter the pathogenicity of these parasites. RESULTS: Classification models for predicting the antitrichomonas activity of molecules were built. These models were employed to screen antiprotozoal drugs, from which 20 were classified as active. The in vitro experiments showed moderate to high activity for 19 of the molecules at 10 MUg/ml, while 3 compounds yielded higher activity than the reference at 1 MUg/ml. The 11 most active chemicals were evaluated in vivo using Naval Medical Research Institute (NMRI) mice. CONCLUSION: Benznidazole showed similar results as metronidazole, and can thus be considered as a potential candidate in antitrichomonas therapy. PMID- 29589478 TI - Advantages and disadvantages of interdisciplinary consultation in the prescription of assistive technologies for mobility limitations. AB - PURPOSE: To explore the advantages and disadvantages experienced by professionals in interdisciplinary consultation involving the user, prescriber and technician in the prescription of assistive technologies for mobility limitations. METHOD: Cross-sectional study. Prescribers (N = 39) and orthopaedic technicians (N = 50), who were regularly involved in an interdisciplinary consultation completed a questionnaire about advantages and disadvantages of the interdisciplinary consultation. RESULTS: Advantages of the interdisciplinary consultation were mentioned within all CanMEDS areas of medical practice, including better and quicker prescription of the assistive technology, shared knowledge of medical diagnosis and device possibilities, shared decision making of the device prescription and clear communication rules. Disadvantages were mentioned in the CanMEDS areas management and collaboration, including planning problems (financial) reimbursement of this type of consultation, and time efficiency. On a 10-point scale, mean (standard deviation) rates of interdisciplinary consultations were 7.9 (0.6) according to prescribers, and 7.8 (0.9) by technicians. All participants wanted to continue the interdisciplinary consultation. CONCLUSIONS: Prescribers and technicians in the field of assistive technologies for walking mobility limitations appreciate an interdisciplinary consultation. Advantages are found in all CanMEDS areas, whereas disadvantages only concern coordination. It should be encouraged to realize this kind of consultation in all situations where such technologies are prescribed. Implications for rehabilitation Interdisciplinary consultation involving the user, prescriber and technician to prescribe assistive technologies for mobility limitations has many advantages in all CanMEDS areas of medical practice, and few disadvantages, related to management and collaboration only. The disadvantages of interdisciplinary consultation, such as (financial) reimbursement by health insurance companies, have to be taken into account. Professionals in the field of ankle-foot-orthoses and orthopaedic shoes (medical specialist as prescriber and orthopaedic technician) who are involved in interdisciplinary consultation appreciate it and want to continue. PMID- 29589479 TI - Magnetically assisted intraperitoneal drug delivery for cancer chemotherapy. AB - Intraperitoneal (IP) chemotherapy has revived hopes during the past few years for the management of peritoneal disseminations of digestive and gynecological cancers. Nevertheless, a poor drug penetration is one key drawback of IP chemotherapy since peritoneal neoplasms are notoriously resistant to drug penetration. Recent preclinical studies have focused on targeting the aberrant tumor microenvironment to improve intratumoral drug transport. However, tumor stroma targeting therapies have limited therapeutic windows and show variable outcomes across different cohort of patients. Therefore, the development of new strategies for improving the efficacy of IP chemotherapy is a certain need. In this work, we propose a new magnetically assisted strategy to elevate drug penetration into peritoneal tumor nodules and improve IP chemotherapy. A computational model was developed to assess the feasibility and predictability of the proposed active drug delivery method. The key tumor pathophysiology, including a spatially heterogeneous construct of leaky vasculature, nonfunctional lymphatics, and dense extracellular matrix (ECM), was reconstructed in silico. The transport of intraperitoneally injected magnetic nanoparticles (MNPs) inside tumors was simulated and compared with the transport of free cytotoxic agents. Our results on magnetically assisted delivery showed an order of magnitude increase in the final intratumoral concentration of drug-coated MNPs with respect to free cytotoxic agents. The intermediate MNPs with the radius range of 200-300 nm yield optimal magnetic drug targeting (MDT) performance in 5-10 mm tumors while the MDT performance remains essentially the same over a large particle radius range of 100-500 nm for a 1 mm radius small tumor. The success of MDT in larger tumors (5-10 mm in radius) was found to be markedly dependent on the choice of magnet strength and tumor-magnet distance while these two parameters were less of a concern in small tumors. We also validated in silico results against experimental results related to tumor interstitial hypertension, conventional IP chemoperfusion, and magnetically actuated movement of MNPs in excised tissue. PMID- 29589480 TI - Threshold values of ankle dorsiflexion and gross motor function in 60 children with cerebral palsy. AB - Background and purpose - Threshold values defining 3 categories of passive range of motion are used in the Cerebral Palsy follow-Up Program to guide clinical decisions. The aim of this study was to investigate the threshold values by testing the hypothesis that passive range of motion in ankle dorsiflexion is associated with gross motor function and that function differs between the groups of participants in each category. Patients and methods - We analyzed data from 60 ambulatory children (aged 5-9 years) with spastic cerebral palsy. Outcomes were passive range of motion in ankle dorsiflexion with flexed and extended knee and gross motor function (Gait Deviation Index, Gait Variable Score of the ankle, peak dorsiflexion during gait, 1-minute walk, Gross Motor Function Measure, the Pediatric Quality of Life Inventory Cerebral Palsy Module, and Pediatric Outcomes Data Collection Instrument). Results - Significant (p < 0.05) and moderate correlations were documented for range of motion versus Gait Variable Score of the ankle (r = -0.37 and r = -0.37) and range of motion versus peak dorsiflexion (r = 0.49 and r = 0.55). Differences between the groups formed by the categories were shown for Gait Variable Score of the ankle and peak dorsiflexion (p < 0.05). No other significant correlations or differences between the categories were observed. Interpretation - The results suggest that threshold values for ankle dorsiflexion used in the Cerebral Palsy follow-Up Program are of limited clinical value in assessing overall gross motor function, but may be used to identify deviations in ankle-specific gait function. PMID- 29589481 TI - Exploring the Potential of Participatory Theatre to Reduce Stigma and Promote Health Equity for Lesbian, Gay, Bisexual, and Transgender (LGBT) People in Swaziland and Lesotho. AB - Stigma and discrimination affecting lesbian, gay, bisexual, and transgender (LGBT) people compromise health and human rights and exacerbate the HIV epidemic. Scant research has explored effective LGBT stigma reduction strategies in low- and middle-income countries. We developed and pilot-tested a participatory theatre intervention (PTI) to reduce LGBT stigma in Swaziland and Lesotho, countries with the world's highest HIV prevalence. We collected preliminary data from in-depth interviews with LGBT people in Lesotho and Swaziland to enhance understanding of LGBT stigma. Local LGBT and theatre groups worked with these data to create a 2-hour PTI composed of three skits on LGBT stigma in health care, family, and community settings in Swaziland (Manzini) and Lesotho (Maseru, Mapoteng). Participants ( n = 106; nursing students, health care providers, educators, community members) completed 12 focus groups following the PTI. We conducted thematic analysis to understand reactions to the PTI. Focus groups revealed the PTI increased understanding of LGBT persons and issues, increased empathy, and fostered self-reflection of personal biases. Increased understanding included enhanced awareness of the negative impacts of LGBT stigma, and of LGBT people's lived experiences and issues. Participants discussed changes in attitude and perspective through self-reflection and learning. The format of the theatre performance was described as conducive to learning and preferred over more conventional educational methods. Findings indicate changed attitudes and awareness toward LGBT persons and issues following a PTI in Swaziland and Lesotho. Stigma reduction interventions may help mitigate barriers to HIV prevention, treatment, and care in these settings with a high burden of HIV. PMID- 29589482 TI - Psychosocial Determinants of Food Acquisition and Preparation in Low-Income, Urban African American Households. AB - BACKGROUND: Psychosocial factors are important determinants of health behaviors and diet-related outcomes, yet relatively little work has explored their relation to food-purchasing and preparation behaviors in low-income populations. AIM: To evaluate the psychosocial factors associated with food-related behaviors. METHODS: Cross-sectional data collected from 465 low-income African American adult caregivers in the baseline evaluation of the B'more Healthy Communities for Kids obesity prevention trial. Questionnaires were used to assess household sociodemographic characteristics, food sources frequently used, and food preparation and food acquisition behaviors. Multiple linear regression models explored the associations between caregiver psychosocial variables and food related behaviors, controlling for caregivers' age, sex, household income, household size, and food assistance participation. RESULTS: Caregivers purchased prepared food at carry-outs on average 3.8 times (standard deviation [ SD] = 4.6) within 30 days. Less healthy foods were acquired 2 times more frequently than healthier foods ( p < .001). Higher food-related behavioral intention and self efficacy scores were positively associated with healthier food acquisition (beta = 0.7; 95% confidence interval [CI] [0.09, 1.4]; beta = 0.04; 95% CI [0.02, 0.06]) and negatively associated with frequency of purchasing at prepared food sources (beta = -0.4; 95% CI [-0.6, -0.2]; beta = -0.5; 95% CI [-0.7, -0.3]), respectively. Higher nutrition knowledge was associated with lower frequency of purchasing food at prepared food venues (beta = -0.7; 95% CI: [-1.2, -0.2]). DISCUSSION: Our findings indicate a positive association between psychosocial determinants and healthier food acquisition and food preparation behaviors. CONCLUSION: Interventions that affect psychosocial factors (i.e., food-related behavioral intentions and self-efficacy) may have the potential to increase healthier food preparation and food-purchasing practices among low-income African American families. PMID- 29589483 TI - Discovery, gene modification, and optimization of fermentation of an enduracidin producing strain. AB - Enduracidin significantly inhibits Gram-positive bacteria and had been widely used in many fields. However, as the poor technology for production of enduracidin and its scarcity, identification of novel strategies for production of enduracidin is important. Our group developed two methods to improve the yield of the production of enduracidin. The yield of enduracidin was increased by three to fivefold. The highest yields of enduracidin A and enduracidin B achieved were 63.7 and 82.13 mg/ml. Thus, our results might provide a new reference method for the industrial production of enduracidin. PMID- 29589484 TI - New secoiridoids from the fruits of Ligustrum lucidum. AB - Three new secoiridoids, nuezhenelenoliciside (1), isojaslanceoside B (2), 6'-O trans-cinnamoyl-secologanoside (3), were isolated from the dried fruits of Ligustrum lucidum. Their structures were elucidated by comprehensive spectroscopic analysis. Among them, 1 featured a rare rearrangement product of secoiridoid, which underwent the cleavage of chemical bond between C-1 and O-2, and the reformation of a new iridoid ring between C-8 and O-2. In addition, all compounds were tested for their osteogenic activity on pre-osteoblastic MC3T3-E1 cells. As a result, 1 and 3 exhibited potent effects on promoting cell proliferation of pre-osteoblast cells. PMID- 29589485 TI - Characterization of a New HIV-1 CRF01_AE/CRF07_BC Recombinant Virus Form Among Men Who Have Sex with Men in Beijing, China. AB - Recent studies have revealed that three major viral strains (CRF07_BC, CRF01_AE, and subtype B) have been cocirculating among men who have sex with men in Beijing. Cocirculation of multiple subtypes in the same population contributes significantly to the emergence of recombinant viruses. This study reports a near full-length genome of a novel, second-generation HIV-1 recombinant (BJ2015EU16) between CRF07_BC and CRF01_AE. The analysis of BJ2015EU16 shows that the genome comprises three interlaced segments, including two CRF07_BC and one CRF01_AE segments, with CRF07_BC as the backbone. There were two recombinant breakpoints in the vpu and env genes of BJ2015EU16. This is different from a previously identified CRF01_AE/07_BC recombinant strain from Beijing. The new emergence of the unique recombinant form increases the complexity of the HIV epidemic in the Beijing homosexual group, and the ongoing generation of recombinant viruses may provide an important basis for future analysis of the recombination mechanism of HIV-1. PMID- 29589486 TI - Advances in chemical pharmacotherapy for the treatment of pediatric immune thrombocytopenia. AB - INTRODUCTION: Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder of heterogeneous pathophysiological mechanisms. Treatment endpoints include elevation of platelets and reduction of bleeding risk, elevation of quality of life, reduction of concomitant therapies and prevention from bleeding. Persistent and chronic ITP is more common in adults but occurs in children. Standard therapies include corticosteroids and immunoglobulins, both associated with side effects. There are new treatments, such as thrombopoietin-receptor agonists and promising investigational drugs. Areas covered: Experience from the management of adults is valuable for children with persistent and chronic symptomatic ITP. In this review first- and second-line therapies, but also investigational drugs for children with ITP are discussed. Expert opinion: Although time-consuming and based on experience, children with no or mild bleeding can be safely managed with a watch and wait strategy. Chronic symptomatic immune thrombocytopenia is an area of second-line treatments based on a highly individualized approach. Furthermore, there are investigational drugs, which may also be of benefit for children with chronic symptomatic ITP. PMID- 29589487 TI - Search of vasopressin analogs with antiproliferative activity on small-cell lung cancer: drug design based on two different approaches. AB - AIM: Development of compounds with therapeutic application requires the interaction of different disciplines. Several tumors express vasopressin (AVP; arginine vasopressin) receptors with contrasting effects depending on receptor subtype. Desmopressin (dDAVP) is an AVP-selective analog with antiproliferative properties. In this work, an evolutionary approach and a rational strategy were applied in order to design novel AVP analogs. RESULTS: We designed two novel analogs; dDInotocin (dDINT, insect analog), and [V4Q5]dDAVP, and demonstrated the importance of the dDAVP conformational loop for its antiproliferative activity. [V4Q5] dDAVP showed major cytostatic effect on lung cancer cells than dDAVP and its cytostatic effect was abolished by V2R blockade. CONCLUSION: Combination of these strategies could provide the basis for future studies for the development of improved compounds with potential therapeutic applications. PMID- 29589488 TI - Associations between gene polymorphisms and treatment outcomes of methotrexate in patients with juvenile idiopathic arthritis. AB - AIM: Performance of a meta-analysis with respect to the genetic predictors of methotrexate (MTX) treatment outcomes, efficacy and toxicity, in patients with juvenile idiopathic arthritis (JIA). METHODS: Databases of OVID MEDLINE and OVID EMBASE were searched to collect the studies addressing correlations between gene polymorphisms and efficacy and/or toxicity in MTX-treated JIA patients. Pooled odds ratios (ORs) with 95% CIs were estimated in allelic, recessive and/or dominant models. RESULTS: With regards to efficacy, the C677T (rs1801133) polymorphism in MTHFR was associated with nonresponse to MTX treatment in a recessive model (OR: 0.40; 95% CI: 0.19-0.84). For associations with toxicity, the MTHFR C677T (rs1801133) polymorphism was associated with presenting overall adverse events in an allelic model (OR: 1.54; 95% CI: 1.07-2.22) and a dominant model (OR: 1.70; 95% CI: 1.08-2.68). CONCLUSION: C677T (rs1801133) polymorphism in MTHFR predicts nonresponse and/or adverse effects of MTX treatment in JIA patients.

PMID- 29589491 TI - Risk factors for progression of articular cartilage damage after anatomical anterior cruciate ligament reconstruction. AB - Aims: To investigate the risk factors for progression of articular cartilage damage after anatomical anterior cruciate ligament (ACL) reconstruction. Patients and Methods: A total of 174 patients who underwent second-look arthroscopic evaluation after anatomical ACL reconstruction were enrolled in this study. The graded condition of the articular cartilage at the time of ACL reconstruction was compared with that at second-look arthroscopy. Age, gender, body mass index (BMI), ACL reconstruction technique, meniscal conditions, and other variables were assessed by regression analysis as risk factors for progression of damage to the articular cartilage. Results: In the medial compartment, multivariable logistic regression analysis indicated that partial medial meniscectomy (odds ratio (OR) 6.82, 95% confidence interval (CI) 2.11 to 22.04, p = 0.001), pivot shift test grade at the final follow-up (OR 3.53, CI 1.39 to 8.96, p = 0.008), BMI (OR 1.15, CI 1.03 to 1.28, p = 0.015) and medial meniscal repair (OR 3.19, CI 1.24 to 8.21, p = 0.016) were significant risk factors for progression of cartilage damage. In the lateral compartment, partial lateral meniscectomy (OR 10.94, CI 4.14 to 28.92, p < 0.001) and side-to-side differences in anterior knee laxity at follow-up (OR 0.63, p = 0.001) were significant risk factors. Conclusion: Partial meniscectomy was found to be strongly associated with the progression of articular cartilage damage despite r anatomical ACL reconstruction.

AB - Aims: Identifying predictors of compartment syndrome in the foot after a fracture of the calcaneus may lead to earlier diagnosis and treatment. The aim of our study was to identify any such predictors. Patients and Methods: We retrospectively reviewed 303 patients (313 fractures) with a fracture of the calcaneus who presented to us between October 2008 and September 2016. The presence of compartment syndrome and potential predictors were identified by reviewing their medical records. Potential predictors included age, gender, concomitant foot injury, mechanism of injury, fracture classification, time from injury to admission, underlying illness, use of anticoagulant/antiplatelet agents, smoking status and occupation. Associations with predictors were analyzed using logistic regression analysis. Results: Of the 313 fractures of the calcaneus, 12 (3.8%) developed a compartment syndrome. A Sanders type IV fracture was the only strongly associated factor (odds ratio 21.67, p = 0.007). Other variables did not reach statistical significance. Conclusion: A Sanders type IV fracture is the best predictor of compartment syndrome after a fracture of the calcaneus. Cite this article: Bone Joint J 2018;100-B:303-8. PMID- 29589493 TI - Lateral condylar fractures of the humerus in children. AB - Aims: Displaced fractures of the lateral condyle of the humerus are frequently managed surgically with the aim of avoiding nonunion, malunion, disturbances of growth and later arthritis. The ideal method of fixation is however not known, and treatment varies between surgeons and hospitals. The aim of this study was to compare the outcome of two well-established forms of surgical treatment, Kirschner wire (K-wire) and screw fixation. Patients and Methods: A retrospective cohort study of children who underwent surgical treatment for a fracture of the lateral condyle of the humerus between January 2005 and December 2014 at two centres was undertaken. Pre, intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean age at the time of injury was 5.8 years (0 to 15) with a male:female patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture and the fracture was displaced by > 2 mm in 228 (68%). In all, 235 patients underwent K-wire fixation and 101 had screw fixation. Results: There was a higher rate of nonunion with K wire fixation (p = 0.02). There was no difference in Baumann's angle, carrying angle or the rate of major complications between the two groups. No benefit was obtained by immobilizing the elbow for more than four weeks in either group. No short-term complications were seen when fixation crossed the lateral ossific nucleus. Conclusion: Fixation of lateral condylar humeral fractures in children using either K-wires or screws gives satisfactory results. Proponents of both techniques may find justification of their methods in our data, but prospective, randomized trials with long-term follow-up are required to confirm the findings, which suggest a higher rate of nonunion with K-wire fixation.

PMID- 29589494 TI - Intercalary reconstruction of femur after tumour resection: is a vascularized fibular autograft plus allograft a long-lasting solution? AB - Aims: After intercalary resection of a bone tumour from the femur, reconstruction with a vascularized fibular graft (VFG) and massive allograft is considered a reliable method of treatment. However, little is known about the long-term outcome of this procedure. The aims of this study were to determine whether the morbidity of this procedure was comparable to that of other reconstructive techniques, if it was possible to achieve a satisfactory functional result, and whether biological reconstruction with a VFG and massive allograft could achieve a durable, long-lasting reconstruction. Patients and Methods: A total of 23 patients with a mean age of 16 years (five to 40) who had undergone resection of an intercalary bone tumour of the femur and reconstruction with a VFG and allograft were reviewed clinically and radiologically. The mean follow-up was 141 months (24 to 313). The mean length of the fibular graft was 18 cm (12 to 29). Full weight-bearing without a brace was allowed after a mean of 13 months (seven to 26). Results: At final follow-up, the mean Musculoskeletal Tumor Society Score of 22 evaluable patients was 94% (73 to 100). Eight major complications, five fractures (21.7%), and three nonunions (13%) were seen in seven patients (30.4%). Revision-free survival was 72.3% at five, ten, and 15 years, with fracture and nonunion needing surgery as failure endpoints. Overall survival, with removal of allograft or amputation as failure endpoints, was 94.4% at five, ten, and 15 years. Discussion: There were no complications needing surgical revision after five years had elapsed from surgery, suggesting that the mechanical strength of the implant improves with time, thereby decreasing the risk of complications. In young patients with an intercalary bone tumour of the femur, combining a VFG and massive allograft may result in a reconstruction that lasts a lifetime.

AB - Aims: The intra-articular administration of tranexamic acid (TXA) has been shown to be effective in reducing blood loss in unicompartmental knee arthroplasty and anterior cruciate reconstruction. The effects on human articular cartilage, however, remains unknown. Our aim, in this study, was to investigate any detrimental effect of TXA on chondrocytes, and to establish if there was a safe dose for its use in clinical practice. The hypothesis was that TXA would cause a dose-dependent damage to human articular cartilage. Materials and Methods: The cellular morphology, adhesion, metabolic activity, and viability of human chondrocytes when increasing the concentration (0 mg/ml to 40 mg/ml) and length of exposure to TXA (0 to 12 hours) were analyzed in a 2D model. This was then repeated, excluding cellular adhesion, in a 3D model and confirmed in viable samples of articular cartilage. Results: Increasing concentrations above 20 mg/ml resulted in atypical morphology, reduced cellular adhesion and metabolic activity associated with increased chondrocyte death. However, the cell matrix was not affected by the concentration of TXA or the length of exposure, and offered cellular protection for concentrations below 20 mg/ml. Conclusion: These results show that when in vitro chondrocytes are exposed to higher concentrations of TXA, such as that expected following recommended intra-articular administration, cytotoxicity is observed. This effect is dose-dependent, such that a tissue concentration of 10 mg/ml to 20 mg/ml could be expected to be safe. Cite this article: Bone Joint J 2018;100-B:404-12. PMID- 29589495 TI - Reverse shoulder arthroplasty for type 1 sequelae of a fracture of the proximal humerus. AB - Aims: The aim of this study was to analyze the results of reverse shoulder arthroplasty (RSA) in patients with type 1 sequelae of a fracture of the proximal humerus in association with rotator cuff deficiency or severe stiffness of the shoulder. Patients and Methods: A total of 38 patients were included: 28 women and ten men. Their mean age at the time of arthroplasty was 73 years (54 to 91). Before the RSA, 18 patients had been treated with open reduction and internal fixation following a fracture. A total of 22 patients had a rotator cuff tear and 11 had severe stiffness of the shoulder with < 0 degrees of external rotation. The mean follow-up was 4.3 years (1.5 to 10). The Constant score and the range of movement of the shoulder were recorded preoperatively and at final follow-up. Preoperatively, radiographs in two planes were performed, as well as CT or arthro CT scans; radiographs were also performed at final follow-up. Results: The mean Constant score improved from 25 points (5 to 47) preoperatively to 57 points (15 to 81) postoperatively. The mean forward elevation of the shoulder increased from 73 degrees (10 degrees to 130 degrees ) preoperatively to 117 degrees (15 degrees to 170 degrees ) postoperatively. Previous surgery did not influence the outcome. Patients with rotator cuff tears had lower Constant scores than patients without (p = 0.037). Those with preoperative stiffness of the shoulder had lower postoperative external rotation compared with patients without stiffness (p = 0.046). There was no radiographic evidence of loosening. Three complications occurred, leading to revision surgery in two patients. In all, 17 patients rated their result as very good (45%), another 17 as good (45%), two as satisfactory (5%), and two as unsatisfactory (5%). Discussion: RSA is an effective form of treatment for patients with type 1 sequelae of a fracture of the proximal humerus associated with rotator cuff deficiency or stiffness of the shoulder, with high rates of satisfaction. Rotator cuff tears and stiffness of the shoulder had an adverse effect on the clinical outcome. Cite this article: Bone Joint J 2018;100 B:318-23. PMID- 29589497 TI - Risk factors for recurrent instability or revision surgery following arthroscopic Bankart repair. AB - Aims: The factors that predispose to recurrent instability and revision stabilization procedures after arthroscopic Bankart repair for anterior glenohumeral instability remain unclear. We sought to determine the rate and risk factors associated with ongoing instability in patients undergoing arthroscopic Bankart repair for instability of the shoulder. Materials and Methods: We used the Statewide Planning and Research Cooperative System (SPARCS) database to identify patients with a diagnosis of anterior instability of the shoulder undergoing arthroscopic Bankart repair between 2003 and 2011. Patients were followed for a minimum of three years. Baseline demographics and subsequent further surgery to the ipsilateral shoulder were analyzed. Multivariate analysis was used to identify independent risk factors for recurrent instability. Results: A total of 5719 patients were analyzed. Their mean age was 24.9 years (sd 9.3); 4013 (70.2%) were male. A total of 461 (8.1%) underwent a further procedure involving the ipsilateral shoulder at a mean of 31.5 months (sd 23.8) postoperatively; 117 (2.1%) had a closed reduction and 344 (6.0%) had further surgery. Revision arthroscopic Bankart repair was the most common subsequent surgical procedure (223; 65.4%). Independent risk factors for recurrent instability were: age < 19 years (odds ratio 1.86), Caucasian ethnicity (hazard ratio 1.42), bilateral instability of the shoulder (hazard ratio 2.17), and a history of closed reduction(s) prior to the initial repair (hazard ratio 2.45). Revision arthroscopic Bankart repair was associated with significantly higher rates of ongoing persistent instability than revision open stabilization (12.4% vs 5.1%, p = 0.041). Conclusion: The incidence of a further procedure being required in patients undergoing arthroscopic Bankart repair for anterior glenohumeral instability was 8.1%. Younger age, Caucasian race, bilateral instability, and closed reduction prior to the initial repair were independent risk factors for recurrent instability, while subsequent revision arthroscopic Bankart repair had significantly higher rates of persistent instability than subsequent open revision procedures.

AB - Aims: The use of a noninvasive growing endoprosthesis in the management of primary bone tumours in children is well established. However, the efficacy of such a prosthesis in those requiring a revision procedure has yet to be established. The aim of this series was to present our results using extendable prostheses for the revision of previous endoprostheses. Patients and Methods: All patients who had a noninvasive growing endoprosthesis inserted at the time of a revision procedure were identified from our database. A total of 21 patients (seven female patients, 14 male) with a mean age of 20.4 years (10 to 41) at the time of revision were included. The indications for revision were mechanical failure, trauma or infection with a residual leg-length discrepancy. The mean follow-up was 70 months (17 to 128). The mean shortening prior to revision was 44 mm (10 to 100). Lengthening was performed in all but one patient with a mean lengthening of 51 mm (5 to 140). Results: The mean residual leg length discrepancy at final follow-up of 15 mm (1 to 35). Two patients developed a deep periprosthetic infection, of whom one required amputation to eradicate the infection; the other required two-stage revision. Implant survival according to Henderson criteria was 86% at two years and 72% at five years. When considering revision for any cause (including revision of the growing prosthesis to a non growing prosthesis), revision-free implant survival was 75% at two years, but reduced to 55% at five years. Conclusion: Our experience indicates that revision surgery using a noninvasive growing endoprosthesis is a successful option for improving leg length discrepancy and should be considered in patients with significant leg-length discrepancy requiring a revision procedure.

AB - Aims: Since long-term outcome of teres major tendon transfer surgery for irreparable posterosuperior rotator cuff (RC) tears is largely unknown, the primary aim of this study was to evaluate the long-term outcome of the teres major transfer. We also aimed to report on the results of a cohort of patients with a similar indication for surgery that underwent a latissimus dorsi tendon transfer. Patients and Methods: Patients and Methods In this prospective cohort study, we reported on the long-term results of 20 consecutive patients with a teres major tendon transfer for irreparable massive posterosuperior RC tears. Additionally, we reported on the results of the latissimus dorsi tendon transfer (n = 19). The mean age was 60 years (47 to 77). Outcomes included the Constant score (CS), and pain at rest and during movement using the Visual Analogue Scale (VAS). Results: At a mean of ten years (8 to 12) following teres major transfer, the CS was still 23 points (95% confidence interval (CI) 14.6 to 30.9, p < 0.001) higher than preoperatively. VAS for pain at rest (21 mm, 95% CI 4.0 to 38.9, p = 0.016) and movement (31 mm, 95% CI 16.0 to 45.1, p < 0.001) were lower than preoperatively. We also found an increase in CS (32 points, 95% CI 23.4 to 40.2, p < 0.001) and reduction of pain (26 mm, 95% CI 9.9 to 41.8, p = 0.001) six years after latissimus dorsi transfer. Conclusion: Teres major tendon transfer is a treatment option to gain shoulder function and reduce pain in patients with an irreparable posterosuperior RC tear at a mean follow-up of ten years. The teres major tendon might be a valuable alternative to the commonly performed latissimus dorsi tendon transfer in the treatment of irreparable posterosuperior RC tears.

PMID- 29589500 TI - The effect of triclosan-coated sutures on the rate of surgical site infection after hip and knee arthroplasty: a double-blind randomized controlled trial of 2546 patients. AB - Aims: Surgical site infection (SSI) is a common complication of surgery with an incidence of about 1% in the United Kingdom. Sutures can lead to the development of a SSI, as micro-organisms can colonize the suture as it is implanted. Triclosan-coated sutures, being antimicrobical, were developed to reduce the rate of SSI. Our aim was to assess whether triclosan-coated sutures cause a reduction in SSIs following arthroplasty of the hip and knee. Patients and Methods: This two-arm, parallel, double-blinded study involved 2546 patients undergoing elective total hip (THA) and total knee arthroplasty (TKA) at three hospitals. A total of 1323 were quasi-randomized to a standard suture group, and 1223 being quasi-randomized to the triclosan-coated suture group. The primary endpoint was the rate of SSI at 30 days postoperatively. Results: The baseline characteristics of age, gender and comorbidities were well matched in the two groups. The rates of superficial SSI were 0.8% in the control group and 0.7% in the intervention group (p = 0.651), and when deep and superficial SSIs were combined the rates were 2.5% and 1.8 (p = 0.266). The length of stay in hospital and the rates of medical complications did not differ significantly between the groups (p = 1.000). Conclusion: This trial provided no evidence that the use of triclosan coated sutures at THA and TKA leads to a reduction in the rate of SSI. Cite this article: Bone Joint J 2018;100-B:296-302. PMID- 29589501 TI - Glenoid osteotomy for atraumatic posteroinferior shoulder instability associated with glenoid dysplasia. AB - Aims: We report the clinical results of glenoid osteotomy in patients with atraumatic posteroinferior instability associated with glenoid dysplasia. Patients and Methods: The study reports results in 211 patients (249 shoulders) with atraumatic posteroinferior instability. The patients comprised 63 men and 148 women with a mean age of 20 years. The posteroinferior glenoid surface was elevated by osteotomy at the scapular neck. A body spica was applied to maintain the arm perpendicular to the glenoid for two weeks postoperatively. Clinical results were evaluated using the Rowe score and Japan Shoulder Society Shoulder Instability Score (JSS-SIS); bone union, osteoarthrosis, and articular congruity were examined on plain radiographs. Results: The Rowe score improved from 36 to 88 points, and the JSS-SIS improved from 47 to 81 points. All shoulders exhibited union without progression of osteoarthritis except one shoulder, which showed osteoarthritic change due to a previous surgery before the glenoid osteotomy. All but three shoulders showed improvement in joint congruency. Eight patients developed disordered scapulohumeral rhythm during arm elevation, and 12 patients required additional open stabilization for anterior instability. Conclusion: Good results can be expected from glenoid osteotomy in patients with atraumatic posteroinferior instability associated with glenoid dysplasia.

PMID- 29589502 TI - Comparison between a multicentre, collaborative, closed-loop audit assessing management of supracondylar fractures and the British Orthopaedic Association Standard for Trauma 11 (BOAST 11) guidelines. AB - Aims: Supracondylar fractures are the most frequently occurring paediatric fractures about the elbow and may be associated with a neurovascular injury. The British Orthopaedic Association Standards for Trauma 11 (BOAST 11) guidelines describe best practice for supracondylar fracture management. This study aimed to assess whether emergency departments in the United Kingdom adhere to BOAST 11 standard 1: a documented assessment, performed on presentation, must include the status of the radial pulse, digital capillary refill time, and the individual function of the radial, median (including the anterior interosseous), and ulnar nerves. Materials and Methods: Stage 1: We conducted a multicentre, retrospective audit of adherence to BOAST 11 standard 1. Data were collected from eight hospitals in the United Kingdom. A total of 433 children with Gartland type 2 or 3 supracondylar fractures were eligible for inclusion. A centrally created data collection sheet was used to guide objective analysis of whether BOAST 11 standard 1 was adhered to. Stage 2: We created a quality improvement proforma for use in emergency departments. This was piloted in one of the hospitals used in the primary audit and was re-audited using equivalent methodology. In all, 102 patients presenting between January 2016 and July 2017 were eligible for inclusion in the re-audit. Results: Stage 1: Of 433 patient notes audited, adherence to BOAST 11 standard 1 was between 201 (46%) and 232 (54%) for the motor and sensory function of the individual nerves specified, 318 (73%) for radial pulse, and 247 (57%) for digital capillary refill time. Stage 2: Of 102 patient notes audited, adherence to BOAST 11 standard 1 improved to between 72 (71%) and 80 (78%) for motor and sensory function of the nerves, to 84 (82%) for radial pulse, and to 82 (80%) for digital capillary refill time. Of the 102 case notes reviewed in stage 2, only 44 (43%) used the quality improvement proforma; when the proforma was used, adherence improved to between 40 (91%) and 43 (98%) throughout. Conclusion: Adherence to BOAST 11 standard 1 is poor in hospitals across the country. This is concerning as neurovascular deficit may be an indication for emergent surgery, and missed neurovascular injury can cause long term, or even permanent, functional impairment. We present a simple proforma that improves adherence to this standard, can easily be implemented into emergency departments, and may improve patient safety.

AB - Aims: The aim of this study was to report the clinical, functional and radiological outcomes of children and adolescents with tibial fractures treated using the Ilizarov method. Patients and Methods: Between 2013 and 2016 a total of 74 children with 75 tibial fractures underwent treatment at our major trauma centre using an Ilizarov frame. Demographic and clinical information from a prospective database was supplemented by routine functional and psychological assessment and a retrospective review of the notes and radiographs. Results: Of the 75 fractures, 26 (35%) were open injuries, of which six (8%) had segmental bone loss. There were associated physeal injuries in 18 (24%), and 12 (16%) involved conversion of treatment following failure of previous management. The remaining children had a closed unstable fracture or significant soft-tissue compromise. The median follow-up was 16 months (7 to 31). All fractures united with a median duration in a frame of 3.6 months (interquartile range 3.1 to 4.6); there was no significant difference between the types of fracture and the demographics of the patients. There were no serious complications and no secondary procedures were required to achieve union. Health-related quality of life measures were available for 60 patients (80%) at a minimum of six months after removal of the frame. These indicated a good return to function (median Paediatric quality of life score, 88.0; interquartile range 70.3 to 100). Conclusion: The Ilizarov method is a safe, effective and reliable method for the treatment of complex paediatric tibial fractures. Cite this article: Bone Joint J 2018;100-B:396-403. PMID- 29589504 TI - Long-term results of the lateral resurfacing elbow arthroplasty. AB - Aims: The aim of this study was to report the long-term outcome and implant survival of the lateral resurfacing elbow (LRE) arthroplasty in the treatment of elbow arthritis. Patients and Methods: We reviewed a consecutive series of 27 patients (30 elbows) who underwent LRE arthroplasty between December 2005 and January 2008. There were 15 women and 12 men, with a mean age of 61 years (25 to 82). The diagnosis was primary hypotrophic osteoarthritis (OA) in 12 patients (14 elbows), post-traumatic osteoarthritis (PTOA) in five (five elbows) and rheumatoid arthritis (RA) in ten patients (11 elbows). The mean clinical outcome scores including the Mayo Elbow Performance Score (MEPS), the American Shoulder and Elbow Surgeons elbow score (ASES-e), the mean range of movement and the radiological outcome were recorded at three, six and 12 months and at a mean final follow-up of 8.3 years (7.3 to 9.4). A one sample t-test comparing pre and postoperative values, and survival analysis using the Kaplan-Meier method were undertaken. Results: A statistically significantly increased outcome score was noted for the whole group at each time interval. This was also significantly increased at each time in each of the subgroups (OA, RA, and PTOA). Implant survivorship was 100%. Conclusion: We found that the LRE arthroplasty, which was initially developed for younger patients with osteoarthritis, is an effective form of surgical treatment for a wider range of patients with more severe degenerative changes, irrespective of their cause. It is therefore a satisfactory alternative to total elbow arthroplasty (TEA) and has lower rates of complications in the subgroups of patients we have studied. It does not require activities to be restricted to the same extent as following TEA. Based on this experience, we now recommend LRE arthroplasty rather than TEA as the primary form of implant for the treatment of patients with OA of the elbow.

PMID- 29589490 TI - Factors associated with health-related quality of life, hip function, and health utility after operative management of femoral neck fractures. AB - Aims: The primary aim of this prognostic study was to identify baseline factors associated with physical health-related quality of life (HRQL) in patients after a femoral neck fracture. The secondary aims were to identify baseline factors associated with mental HRQL, hip function, and health utility. Patients and Methods: Patients who were enrolled in the Fixation using Alternative Implants for the Treatment of Hip Fractures (FAITH) trial completed the 12-item Short Form Health Survey (SF-12), Western Ontario and McMaster Universities Arthritis Index, and EuroQol 5-Dimension at regular intervals for 24 months. We conducted multilevel mixed models to identify factors potentially associated with HRQL. Results: The following were associated with lower physical HRQL: older age (-1.42 for every ten-year increase, 95% confidence interval (CI) -2.17 to -0.67, p < 0.001); female gender (-1.52, 95% CI -3.00 to -0.05, p = 0.04); higher body mass index (-0.69 for every five-point increase, 95% CI -1.36 to -0.02, p = 0.04); American Society of Anesthesiologists class III ( versus class I) (-3.19, 95% CI 5.73 to -0.66, p = 0.01); and sustaining a displaced fracture (-2.18, 95% CI 3.88 to -0.49, p = 0.01). Additional factors were associated with mental HRQL, hip function, and health utility. Conclusion: We identified several baseline factors associated with lower HRQL, hip function, and utility after a femoral neck fracture. These findings may be used by clinicians to inform treatment and outcomes. Cite this article: Bone Joint J 2018;100-B:361-9. PMID- 29589505 TI - Biological augmentation of graft healing in anterior cruciate ligament reconstruction. AB - Aims: The success of anterior cruciate ligament reconstruction (ACLR) depends on osseointegration at the graft-tunnel interface and intra-articular ligamentization. Our aim was to conduct a systematic review of clinical and preclinical studies that evaluated biological augmentation of graft healing in ACLR. Materials and Methods: In all, 1879 studies were identified across three databases. Following assessment against strict criteria, 112 studies were included (20 clinical studies; 92 animal studies). Results: Seven categories of biological interventions were identified: growth factors, biomaterials, stem cells, gene therapy, autologous tissue, biophysical/environmental, and pharmaceuticals. The methodological quality of animal studies was moderate in 97%, but only 10% used clinically relevant outcome measures. The most interventions in clinical trials target the graft-tunnel interface and are applied intraoperatively. Platelet-rich plasma is the most studied intervention, but the clinical outcomes are mixed, and the methodological quality of studies was suboptimal. Other biological therapies investigated in clinical trials include: remnant-augmented ACLR; bone substitutes; calcium phosphate-hybridized grafts; extracorporeal shockwave therapy; and adult autologus non-cultivated stem cells. Conclusion: There is extensive preclinical research supporting the use of biological therapies to augment ACLR. Further clinical studies that meet the minimum standards of reporting are required to determine whether emerging biological strategies will provide tangible benefits in patients undergoing ACLR.

AB - Numerous skill batteries assess fundamental motor skill (e.g., kick, hop) competence. Few skill batteries examine lifelong physical activity skill competence (e.g., resistance training). This study aimed to develop and assess the content validity, test-retest and inter-rater reliability of the "Lifelong Physical Activity Skills Battery". Development of the skill battery occurred in three stages: i) systematic reviews of lifelong physical activity participation rates and existing motor skill assessment tools, ii) practitioner consultation and iii) research expert consultation. The final battery included eight skills: grapevine, golf swing, jog, push-up, squat, tennis forehand, upward dog and warrior I. Adolescents (28 boys, 29 girls; M = 15.8 years, SD = 0.4 years) completed the Lifelong Physical Activity Skills Battery on two occasions two weeks apart. The skill battery was highly reliable (ICC = 0.84, 95% CI = 0.72 0.90) with individual skill reliability scores ranging from moderate (warrior I; ICC = 0.56) to high (tennis forehand; ICC = 0.82). Typical error (4.0; 95% CI 3.4 5.0) and proportional bias (r = -0.21, p = .323) were low. This study has provided preliminary evidence for the content validity and reliability of the Lifelong Physical Activity Skills Battery in an adolescent population. PMID- 29589508 TI - A Longitudinal Analysis of the Relationships of Physical Activity and Body Fat With Nerve Growth Factor and Brain-Derived Neural Factor in Children. AB - BACKGROUND: Nerve growth factor (NGF) and brain-derived neural factor (BDNF) are important for brain function and detectable in the blood. This study explored the longitudinal associations of physical activity and body fat with serum NGF and BDNF in children. METHODS: Two waves of measurements were performed 2 years apart in 8- to 11-year-old children, including physical activity using the ActiGraph model 7164, body composition by dual-energy X-ray absorptiometry, and serum NGF and BDNF determined by multiplex immunoassay. The first wave included 248 children. Full information maximum likelihood estimation with robust standard errors was applied in structural equation modeling. RESULTS: Vigorous physical activity showed a direct positive longitudinal relationship with NGF (standardized coefficient beta = 0.30, P = .01) but not with BDNF (beta = 0.04, P = .84). At the same time, body fat percentage was positively related to both NGF (beta = 0.59, P < .001) and BDNF (beta = 0.17, P = .04). There was an indication of an indirect relationship of vigorous physical activity with NGF (product of unstandardized coefficient beta = -0.18, P = .02) and BDNF (beta = -0.07, P = .05) through the negative relationship with body fat percentage (beta = -0.36, P < .001). CONCLUSIONS: Vigorous physical activity is directly related to serum NGF and indirectly through the level of body fat. The relationships with serum BDNF are more complex. PMID- 29589509 TI - Walking, But Not Other Physical Activity at a Higher Intensity, Is Associated With Improved Kidney Function: A Cross-Sectional Health Survey of General Adult Population. AB - BACKGROUND: Chronic kidney disease is common and brings significant health burden. The purpose of this study was to investigate the relationship between physical activity and kidney function. METHODS: This was a cross-sectional study set in the Nanjing Community Cardiovascular Risk Survey, using random cluster sampling. Questionnaires were completed, wherever possible, through face-to-face interviews. Data on age, sex, body mass index, weekly physical activity, and kidney function were collected. Physical activity was measured by the metabolic equivalent of task-minutes per week and grouped into "walking," "moderate," and "vigorous" according to intensity. Kidney function was measured by the estimated glomerular filtration rate (eGFR, in mL/min/1.73 m2). Regression modeling was used to investigate the proposed relationship with adjustment for other confounding factors. RESULTS: A total of 5824 participants were included, with an average age of 52; 44% were male. The eGFR in average was 76 mL/min/1.73 m2, with 19% >= 90, 67% between 60 and 89, and 14% < 60. In average, the total physical activity during a week was 3644 MET-minutes per week. Moderate activity contributed 64% of the total activity, followed by walking (23%) and vigorous activity (13%). Overall, the total activity was weakly associated with eGFR (P = .039). However, in stratified analysis, only walking-related activity was associated with eGFR (P < .0001) after confounding adjustment. CONCLUSIONS: Walking is associated with improved kidney function.

AB - The circadian clock is a molecular timekeeper that matches endogenous rhythms in diverse traits with 24-h cycles in the external environment. Although a lack of clock resonance to the environment is detrimental to performance, clock phenotypes in wild populations nevertheless deviate substantially from the predicted optimal cycle length of 24 h, and significant genetic variation exists for circadian parameters. Here, we describe covariation between 2 traits considered to reflect adaptation to different aspects of temporal environmental heterogeneity, circadian rhythms (adaptation to daily environmental cycles) and flowering time (adaptation to seasonal cycles), in a Rocky Mountain population of the mustard Boechera stricta, a North American relative of Arabidopsis thaliana. We found that 18 families that differ in circadian period in leaf movement by 3.5 h expressed genetic diversity in first-year growth, reproductive phenology, vegetative size at reproduction, and starch concentration following vernalization. The families exhibited a large (~90-day) range in mean flowering time, even though the spatial scale of population sampling covered only a few hundred meters. Circadian period covaried with other traits such that longer period families flowered earlier and at a larger size, a trait combination predicted to yield a fitness benefit in the wild. Circadian clock research in model systems has previously shown that mutations in clock genes influence phenology. Our results widen the scope of this research by illustrating a link between naturally segregating clock variation and reproductive phenology among wild genotypes, suggesting that the causes of genetic diversity in the clock lie partly in adaptation to seasonal environmental heterogeneity.

AB - BACKGROUND: The epidemic of non-communicable diseases (NCDs) in slums has pushed its residents to heightened vulnerability. The Social Determinants of Health (SDH) framework has been used to understand the social dynamics and impact of NCDs, especially in poorly resourced communities. Whilst the SDH has helped to discredit the characterisation of NCDs as diseases of affluence, its impact on policy has been less definite. Given the multitude of factors that interact in the presentation of NCDs, operationalising the SDH for policies and programmes that account for the contextual complexity of slums has stalled. OBJECTIVE: To organise the complex networks of relations between SDH in slums so as to identify options for Indian municipal policy that are feasible to implement in the short term. METHODS: The study reviews the literature describing SDH in Indian slums, specifically those that establish causal relations between SDH and NCDs. Root cause analysis was then used to organise the identified relations of SDH and NCDs. RESULTS: Although poverty remains the largest structural determinant of health in slums, the multi-dimensional relations between SDH and NCDs are structured around four themes that describe the dynamics of slums, namely scarce clean water, low education, physical (in)activity and transportation. From the reviewed literature, four logic trees visualising the relations between SDH in slums and NCDs were constructed. The logic trees separate symptomatic problems from their more distal causes, and recommendations were formulated based on features of these relationships that are amenable to policy intervention. CONCLUSION: Root cause analysis provides a means to focus the lens of examination of SDH, as evidenced here for Indian slums. It provides a guide for the development of policies that are grounded in the actual health concerns of people in slums, and takes account of the complex pathways through which diseases are socially constituted.

AB - Transient receptor potential (TRP) ion channels are molecular sensors of a large variety of stimuli including temperature, mechanical stress, voltage, small molecules including capsaicin and menthol, and lipids such as phosphatidylinositol 4,5-bisphosphate (PIP2). Since the same TRP channels may respond to different physical and chemical stimuli, they can serve as signal integrators. Many TRP channels are calcium permeable and contribute to Ca2+ homeostasis and signaling. Although the TRP channel family was discovered decades ago, only recently have the structures of many of these channels been solved, largely by cryo-electron microscopy (cryo-EM). Complimentary to cryo-EM, X-ray crystallography provides unique tools to unambiguously identify specific atoms and can be used to study ion binding in channel pores. In this review we describe crystallographic studies of the TRP channel TRPV6. The methodology used in these studies may serve as a template for future structural analyses of different types of TRP and other ion channels. PMID- 29589515 TI - Rheolytic effects of left main mid-shaft/distal stenting: a computational flow dynamic analysis. AB - Background The aim of this study was to evaluate the rheolytic effects of stenting a mid-shaft/distal left main coronary artery (LMCA) lesion with and without ostial coverage. Stenting of the LMCA has emerged as a valid alternative in place of traditional coronary bypass graft surgery. However, in case of mid shaft/distal lesion, there is no consensus regarding the extension of the strut coverage up to the ostium or to stent only the culprit lesion. Methods We reconstructed a left main-left descending coronary artery (LM-LCA)-left circumflex (LCX) bifurcation after analysing 100 consecutive patients (mean age 71.4 +/- 9.3, 49 males) with LM mid-shaft/distal disease. The mean diameter of proximal LM, left anterior descending (LAD) and LCX, evaluated with quantitative coronary angiography (QCA) was 4.62 +/- 0.86 mm, 3.31 +/- 0.92 mm, and 2.74 +/- 0.93 mm, respectively. For the stent simulation, a third-generation, everolimus eluting stent was virtually reconstructed. Results After virtual stenting, the net area averaged wall shear stress (WSS) of the model and the WSS at the LCA-LCX bifurcation resulted higher when the stent covered the culprit mid-shaft lesion only compared with the extension of the stent covering the ostium (3.68 versus 2.06 Pa, p = 0.01 and 3.97 versus 1.98 Pa, p < 0.001, respectively. Similarly, the static pressure and the Reynolds number were significantly higher after stent implantation covering up the ostium. At the ostium, the flow resulted more laminar when stenting only the mid-shaft lesion than including the ostium. Conclusions Although these findings cannot be translated directly into real practice our brief study suggests that stenting lesion 1:1 or extending the stent to cover the LM ostium impacts differently the rheolytic properties of LMCA bifurcation with potential insights for restenosis or thrombosis. PMID- 29589516 TI - Upgrading pyrolytic residue from waste tires to commercial carbon black. AB - The managing and recycling of waste tires has become a worldwide environmental challenge. Among the different disposal methods for waste tires, pyrolysis is regarded as a promising route. How to effectively enhance the added value of pyrolytic residue (PR) from waste tires is a matter of great concern. In this study, the PRs were treated with hydrochloric and hydrofluoric acids in turn under ultrasonic waves. The removal efficiency for the ash and sulfur was investigated. The pyrolytic carbon black (PCB) obtained after treating PR with acids was analyzed by X-ray fluorescence spectrophotometry, Fourier transform infrared spectrometry, X-ray diffractometry, laser Raman spectrometry, scanning electron microscopy, thermogravimetric (TG) analysis, and physisorption apparatus. The properties of PCB were compared with those of commercial carbon black (CCB) N326 and N339. Results showed PRs from waste tires were mainly composed of carbon, sulfur, and ash. The carbon in PCB was mainly from the CCB added during tire manufacture rather than from the pyrolysis of pure rubbers. The removal percentages for the ash and sulfur of PR are 98.33% (from 13.98 wt % down to 0.24 wt %) and 70.16% (from 1.81 wt % down to 0.54 wt %), respectively, in the entire process. The ash was mainly composed of metal oxides, sulfides, and silica. The surface properties, porosity, and morphology of the PCB were all close to those of N326. Therefore, PCB will be a potential alternative of N326 and reused in tire manufacture. This route successfully upgrades PR from waste tires to the high value-added CCB and greatly increases the overall efficiency of the waste tire pyrolysis industry.

AB - The implementation of a recyclable waste management system is a serious challenge for a society that aims to contribute to sustainability. The first operational step of such system is waste collection. In a number of European countries, the solid waste collection system has changed from the conventional kerbside system to a door-to-door collection. However, this type of waste collection system has not yet been introduced in Greece and its public acceptance prior to potential full implementation needs to be considered. This study aims to investigate the willingness of the residents of a Greek city (Xanthi, Thrace) to change from the existing kerbside collection system and initiate and participate in a door-to door recyclable waste collection system instead. A questionnaire was designed and distributed randomly to 150 residents of Xanthi and a statistical analysis was then performed to assess the influence of a number of explanatory variables on recycling behaviour and the willingness to participate in a door-to-door collection system. The findings of this study indicate that most of the respondents (72.7%) were willing to participate in a future door-to-door recyclables collection programme in Xanthi. The factors that influenced the respondents' attitude with regard to such a programme were associated with level of education, their beliefs about the effectiveness of the current recycling system and also their attitudes towards recycling issues in general. Age and religion significantly affected recycling frequency. The survey and statistics presented in this article can be used as a model to assess the behaviour of citizens towards recyclable waste management systems worldwide. PMID- 29589518 TI - Effects of different frequencies of repetitive transcranial magnetic stimulation in stroke patients with non-fluent aphasia: a randomized, sham-controlled study. AB - OBJECTIVE: The purpose of this study was to compare the efficacy of repetitive transcranial magnetic stimulation (rTMS) applied at different frequencies to the contra-lesional hemisphere to optimize the treatment of post-stroke non-fluent aphasia. METHOD: Patients with post-stroke non-fluent aphasia were divided randomly into four groups: a high-frequency rTMS (HF-rTMS) group (10 Hz), a low frequency rTMS (LF-rTMS) group (1 Hz), a sham stimulation group, and a control group. All groups received the standard treatment (consisting of drug therapy, conventional physical exercises, and speech training); in the HF-rTMS and LF rTMS, this was supplemented with magnetic stimulation that targeted the mirror area within the right hemispheric Broca's area. Patients' language ability was assessed prior to, immediately after, and at 2 months post-treatment by the Chinese version of the Western Aphasia Battery (WAB). RESULTS: When measured immediately post-treatment, as well as at 2 months post-treatment, the LF-rTMS group exhibited a more marked improvement than the HF-rTMS group in spontaneous speech, auditory comprehension, and aphasia quotients (AQ). Compared to the control group, the HF-rTMS cohort exhibited significant improvement at 2-months post-treatment in repetition and AQ. CONCLUSIONS: LF-rTMS and HF-rTMS are both beneficial to the recovery of linguistic function in patients with post-stroke non-fluent aphasia. LF-rTMS produced immediate benefits that persisted long-term, while HF-rTMS only produced long-term benefits. In addition, the benefits produced with LF-rTMS were more marked than those produced by HF-rTMS. PMID- 29589520 TI - Insomnia, Posttraumatic Stress Disorder Symptoms, and Danger: Their Impact on Victims' Return to Court for Orders of Protection. AB - The linkages between intimate partner violence (IPV), posttraumatic stress disorder (PTSD), and insomnia have been the subject of inquiry. This study is the first to explore the associations between clinical-level insomnia, PTSD symptoms, danger, and victim socio-demographics, and whether IPV victims pursue permanent orders of protection (OPs). Data for this secondary analysis were collected through surveys, interviews, and reviews of court records on 112 women who resided in upstate New York. Women initiated actions to obtain OPs from the Domestic Violence Intensive Intervention Court (DVIIC), from 2007 to 2008. The following factors were analyzed to determine their impact on whether a woman returned to court: (a) age, (b) race, (c) employment status, (d) perceived danger, (e) PTSD symptoms, and (f) clinical-level insomnia. This study finds that the following factors significantly relate to return to court: race, clinical level insomnia and perceived danger, clinical-level insomnia and PTSD symptoms, and severe danger level. However, in the final multivariate logistic regression, only race emerged as a predictor of whether a woman returned to court. Specifically, women of color were a third less likely to return to court than White women. These results have significant implications for future research and clinical intervention. PMID- 29589521 TI - Grief and Solidarity Reactions 1 Week After an On-Campus Shooting. AB - The impact of interpersonal violence extends beyond the victims and perpetrator(s). The purpose of this research was threefold: (a) to identify whether college students' very early reactions to an on-campus shooting were associated with well-known predictors of distress, (b) to examine whether grief and distress reactions were distinguishable in the early days following a shooting, and (c) to investigate whether a compassionate self-identity was uniquely associated with grief but not distress. Beginning just 3 days after an early morning shooting that killed one student and injured three others, university students ( N = 408) completed an online questionnaire. Grief, but not distress, was associated with a sense of solidarity with other students and a compassionate self-identity. General distress was associated with prior mental health difficulties and exposure to the shooting. Acute stress was positively associated with being female, having prior mental health difficulties, media exposure, perceived similarity to victims, less victim blame, social support, and social strain. Results suggest that grief reactions that arise in the early days following a collective loss may serve as important psychosocial resources in coping with interpersonal violence. PMID- 29589519 TI - Dopamine-mediated calcium channel regulation in synaptic suppression in L. stagnalis interneurons. AB - D2 dopamine receptor-mediated suppression of synaptic transmission from interneurons plays a key role in neurobiological functions across species, ranging from respiration to memory formation. In this study, we investigated the mechanisms of D2 receptor-dependent suppression using soma-soma synapse between respiratory interneuron VD4 and LPeD1 in the mollusk Lymnaea stagnalis (L. stagnalis). We studied the effects of dopamine on voltage-dependent Ca2+ current and synaptic vesicle release from the VD4. We report that dopamine inhibits voltage-dependent Ca2+ current in the VD4 by both voltage-dependent and independent mechanisms. Dopamine also suppresses synaptic vesicle release downstream of activity-dependent Ca2+ influx. Our study demonstrated that dopamine acts through D2 receptors to inhibit interneuron synaptic transmission through both voltage-dependent Ca2+ channel-dependent and -independent pathways. Taken together, these findings expand our understanding of dopamine function and fundamental mechanisms that shape the dynamics of neural circuit. PMID- 29589522 TI - The Circadian Clock of the Ant Camponotus floridanus Is Localized in Dorsal and Lateral Neurons of the Brain. AB - The circadian clock of social insects has become a focal point of interest for research, as social insects show complex forms of timed behavior and organization within their colonies. These behaviors include brood care, nest maintenance, foraging, swarming, defense, and many other tasks, of which several require social synchronization and accurate timing. Ants of the genus Camponotus have been shown to display a variety of daily timed behaviors such as the emergence of males from the nest, foraging, and relocation of brood. Nevertheless, circadian rhythms of isolated individuals have been studied in few ant species, and the circadian clock network in the brain that governs such behaviors remains completely uncharacterized. Here we show that isolated minor workers of Camponotus floridanus exhibit temperature overcompensated free-running locomotor activity rhythms under constant darkness. Under light-dark cycles, most animals are active during day and night, with a slight preference for the night. On the neurobiological level, we show that distinct cell groups in the lateral and dorsal brain of minor workers of C. floridanus are immunostained with an antibody against the clock protein Period (PER) and a lateral group additionally with an antibody against the neuropeptide pigment-dispersing factor (PDF). PER abundance oscillates in a daily manner, and PDF-positive neurites invade most parts of the brain, suggesting that the PER/PDF-positive neurons are bona fide clock neurons that transfer rhythmic signals into the relevant brain areas controlling rhythmic behavior. PMID- 29589523 TI - An Update on JAK Inhibitors. AB - Janus kinases (JAKs) are a family of non-receptor tyrosine kinases, composed by four members, JAK1, JAK2, JAK3 and TYK2. JAKs are involved in different inflammatory and autoimmune diseases, as well as in malignancies, through the activation of the JAK/STAT signalling pathway. Furthermore, the V617F mutation in JAK2 was identified in patients affected by myeloproliferative neoplasms. This knowledge prompted researchers from academia and pharmaceutical companies to investigate this field in order to discover small molecule JAK inhibitors. These efforts recently afforded to the market approval of four JAK inhibitors. Despite the fact that all these drugs are pyrrolo[2,3-d]pyrimidine derivatives, many compounds endowed with different heterocyclic scaffolds have been reported in the literature as selective or multi-JAK inhibitors, and a number of them is currently being evaluated in clinical trials. In this review we will report many representative compounds that have been published in articles or patents in the last five years (period 2013-2017). The inhibitors will be classified on the basis of their chemical structure, focusing, when possible, on their structure activity relationships, selectivity and biological activity. For every class of derivatives, compounds disclosed before 2013 that have entered clinical trials will also be briefly reported, to underline the importance of a particular chemical scaffold in the search for new inhibitors. PMID- 29589524 TI - ABC transporters in extrahepatic tissues: Pharmacological regulation in heart and intestine. AB - ATP binding cassette (ABC) transporters are transmembrane proteins expressed in secretory epithelia like the liver, kidneys and intestine, in epithelia exhibiting barrier function such as the blood-brain barrier and placenta, and to a much lesser extent, in tissues like reproductive organs, lungs, heart and pancreas, among others. They regulate internal distribution of endogenous metabolites and xenobiotics including drugs of therapeutic use and also participate in their elimination from the body. We here describe the function and regulation of ABC transporters in heart and small intestine, as examples of extrahepatic tissues, in which ABC proteins play clearly different roles. In heart, they are involved in tissue pathogenesis as well as in protecting this organ against toxic compounds and drug-induced oxidative stress. The small intestine is highly exposed to therapeutic drugs taken orally and, consequently, ABC transporters localized on its surface strongly influence drug absorption and pharmacokinetics. Examples of the ABC proteins currently described are Multidrug Resistance-associated Proteins 1 and 2 (MRP1 and 2) for heart and small intestine, respectively, and P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) for both organs. PMID- 29589525 TI - Impact of Dysfunctional Protein Catabolism on Macrophage Cholesterol Handling. AB - Protein catabolism in macrophages, which is accomplished mainly through autophagy lysosomal degradation, ubiquitin-proteasome system, and calpains, is disturbed in atheroprone vessels. Moreover, growing evidence suggests that defects in protein catabolism interfere with cholesterol handling in macrophages. Indeed, decreases in autophagy facilitate the deposition of cholesterol in atheroprone macrophages and the subsequent development of vulnerable atherosclerotic plaques due to impaired catabolism of lipid droplets and limited efferocytic clearance of deadly cells. The proteasome is responsible for the degradation of ATP-binding cassette transporters, which leads to impaired cholesterol efflux from macrophages. Overactivation of conventional calpains contributes to the excessive processing of functional proteins, thereby accelerating receptor-mediated uptake of oxidized low-density lipoproteins (LDLs) and slowing cholesterol efflux. Furthermore, calpain-6, an unconventional nonproteolytic calpain in macrophages, potentiates pinocytotic uptake of native LDL and attenuates the efferocytic clearance of deadly cells. Herein, we focus on recent progress in understanding how defective protein catabolism is associated with macrophage cholesterol handling and subsequent atherogenesis. PMID- 29589526 TI - ADAM metalloproteinases as potential drug targets. AB - The ADAMs, together with ADAMTSs and snake venom metalloproteases (SVMPs), are members of the Adamalysin family. Differences in structural organization, functions and localization are known and their domains, catalytic or non catalytic, show key roles in the substrate recognition and protease activity. Some ADAMs, as membrane-bound enzymes, show sheddase activity. Sheddases are key to modulation of functional proteins such as the tumor necrosis factor, growth factors, cytokines and their receptors, adhesion proteins, signaling molecules and stress molecules involved in immunity. These activities take part in the regulation of several physiological and pathological processes including inflammation, tumor growth, metastatic progression and infectious diseases. On these bases, some ADAMs are currently investigated as drug targets to develop new alternative therapies in many fields of medicine. This review will be focused on these aspects. PMID- 29589527 TI - Mechanism and Inhibition of Matrix Metalloproteinases. AB - Matrix metalloproteinases hydrolyze proteins and glycoproteins forming the extracellular matrix, cytokines and growth factors released in the extracellular space, and membrane-bound receptors on the outer cell membrane. The pathological relevance of MMPs has prompted the structural and functional characterization of these enzymes and the development of synthetic inhibitors as possible drug candidates. Recent studies have provided a better understanding of the substrate preference of the different members of the family, and structural data on the mechanism by which these enzymes hydrolyze the substrates. Here, we report the recent advancements in the understanding of the mechanism of collagenolysis and elastolysis, and we discuss the perspectives of new therapeutic strategies for targeting MMPs. PMID- 29589528 TI - Flavonols and flavones - protecting against myocardial ischemia/reperfusion injury by targeting protein kinases. AB - In acute myocardial infarction (AMI) the first line of treatment is to rapidly restore blood flow to the ischemic myocardium to limit infarct size. It is now well established that though clearly beneficial the positive outcomes of this intervention are limited by injury in response to the reperfusion itself in addition to the prior ischemia. This process is described as reperfusion injury and is considered to contribute to the arrhythmias, microvascular dysfunction and impaired cardiac contractility that is observed even after the restoration of coronary blood flow. Thus an important, currently unmet, therapeutic challenge is to address the outcomes of this reperfusion injury. In this article we review the evidence that flavonols and flavones may prove useful in preserving cardiac function after ischemia and reperfusion and consider the possible mechanisms, in particular the inhibition of kinases, by which they may exert protection. PMID- 29589529 TI - Are Carbonic Anhydrases Suitable Targets to Fight Protozoan Parasitic Diseases? AB - Protozoans belonging to Plasmodium, Leishmania and Trypanosoma genera provoke widespread parasitic diseases with few treatment options and many of the clinically used drugs experiencing an extensive drug resistance phenomenon. In the last several years, the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) was cloned and characterized in the genome of these protozoa, with the aim to search for a new drug target for fighting malaria, leishmaniasis and Chagas disease. P. falciparum encodes for a CA (PfCA) belonging to a novel genetic family, the ?-CA class, L. donovani chagasi for a beta-CA (LdcCA), whereas T. cruzi genome contains an alpha-CA (TcCA). These three enzymes were characterized in detail and a number of in vitro potent and selective inhibitors belonging to the sulfonamide, thiol, dithiocarbamate and hydroxamate classes were discovered. Some of these inhibitors were also effective in cell cultures and animal models of protozoan infections, making them of considerable interest for the development of new antiprotozoan drugs with a novel mechanism of action. PMID- 29589530 TI - Virtual screening for development of new effective compounds against Staphylococcus aureus. AB - Staphylococcus aureus is a notorious pathogenic bacterium causing a wide range of diseases from soft-tissue contamination, to more serious and deep-seated infections. This species is highlighted by its ability to express several kinds of virulence factors and to acquire genes related to drug resistance. Target this number of factors to design any drug is not an easy task. In this review we discuss the importance of computational methods to impulse the development of new drugs against S. aureus. The application of docking methods to screen large library of natural or synthetic compounds and to provide insights into action mechanisms is demonstrated. Particularly, highlighted the studies that validated in silico results with biochemical and microbiological assays. We also comment the computer-aided design of new molecules using some known inhibitors. The confirmation of in silico results with biochemical and microbiological assays allowed the identification of lead molecules that could be used for drug design such as rhodomyrtone, quinuclidine, berberine (and their derivative compounds). The fast development in the computational methods is essential to improve our ability to discovery new drugs, as well as to expand understanding about drug target interactions. PMID- 29589531 TI - A Focus on the Synthesis and Pharmacokinetics of Tocainide and its Analogues. AB - BACKGROUND Tocainide is an antiarrhythmic agent belonging to class IB that was primarily used for suppression of symptomatic ventricular arrhythmias. Tocainide was also reported to relieve pain such as tic douloureux, trigemina neuralgia in humans and tinnitus. Significant antinociception, as assayed on the hot-plate test, was observed after intraperitoneal injection of tocainide, too. By the mid 1980s tocainide was emerging as a more consistently effective treatment for myotonic disorders. Numerous reports of serious adverse reactions led to the use of tocainide being discontinued, even though research on tocainide and its analogues, endowed with a better pharmacological profile, is still in progress for their potential usefulness in the treatment of myotonias. This review is focused on the description of the different synthetic routes to racemic and homochiral tocainide developed in the last decades, as well as analytical studies regarding enantioseparation methods. Finally, some analogues of tocainide reported in the literature, most of which with pharmacological studies, have been mentioned. PMID- 29589532 TI - Targeting Gap Junctions: New Insights in the Treatment of Major Depressive Disorder. AB - BACKGROUND: Major depressive disorder (MDD) is a multifactorial chronic and debilitating mood disease with high lifetime prevalence and associated with excess mortality. Treatments of this disease are not effective in all patients showing the need to find new therapeutic targets. OBJECTIVE: This review aims to update our knowledge about the involvement of astroglial gap junctions and hemichannels in MDD and to show how they have become potential targets for the treatment of this pathology. METHODS: The method applied in this review includes a systematic compilation of the relevant literature. RESULTS AND CONCLUSION: The use of rodent models of depression, gene analysis of hippocampal tissues of MDD patients and post-mortem studies of brains from MDD patients suggest that astrocytic gap junction dysfunction may be part of MDD etiologies. Chronic antidepressant treatments of rats, rat cultured cortical astrocytes and human astrocytoma cell lines support the hypothesis that the up-regulation of gap junctional coupling between astrocytes could be an underlying mechanism for the therapeutic effect of antidepressants. However, two recent functional studies suggest that connexin43 hemichannel activity is part of several antidepressants mode of action and that astrocyte gap junctional intercellular communication and hemichannels exert different effects on antidepressant drug response. Even if they emerge as new therapeutic targets for new and more active treatments, further studies are needed to decipher the sophisticated and respective role of astrocytic gap junctions and hemichannels in MDD. PMID- 29589533 TI - Liver and statins: a critical appraisal of the evidence. AB - Adverse drug reactions (ADRs) represent an important cause of morbidity and mortality worldwide. Statins are a class of drugs whose main adverse effects are drug-induced liver injury (DILI) and myopathy. Some of these may be predictable, due to their pharmacokinetic and pharmacodynamic properties, while others, unfortunately, are idiosyncratic. Genetic factors may also influence patient susceptibility to DILI and myopathy in the case of statins. This review will first discuss the role of statins in cardiovascular disease treatment and prevention and the underlying mechanisms of action. Furthermore, to explore the susceptibility of statin-induced adverse events such as myopathy and hepatotoxicity, it will then focus on the recent Genome-Wide Association Studies (GWAS) concerning the transporter genes, Cytochrome P450 (CYP), organic anion transporting polypeptide (OATP) and ABCB1 and ABCC1, which seem to play a role in the development of clinically relevant adverse events. Finally, we appraise the evidence for and against the use of statins in metabolic syndrome and in HCV infected patients, in terms of their safety and efficacy in cardiovascular events. PMID- 29589534 TI - The Role of Inflammation in Neurological Disorders. AB - Traditionally neurological diseases have been classified, on the basis of their pathogenesis, into vascular, degenerative, inflammatory and traumatic diseases. Examples of the main inflammatory neurological diseases include multiple sclerosis, which is characterized by an immune-mediated response against myelin proteins, and meningoencephalitis, where the inflammatory response is triggered by infectious agents. However, recent evidence suggests a potential role of inflammatory mechanisms also in neurological conditions not usually categorized as inflammatory, such as Alzheimer's disease, Parkinson's disease, Huntington' disease, amyotrophic lateral sclerosis, stroke and traumatic brain injuries. The activation of glial cells and of complement-mediated pathways, the synthesis of inflammation mediators, and the recruitment of leukocytes are the key elements of secondary inflammatory injury following a wide spectrum of primary brain injuries. A better understanding of the role that inflammatory processes play in the natural history of diseases is essential in order to identify potential therapeutic targets and to develop integrated pharmacological approaches acting at different levels and stages of the diseases. PMID- 29589535 TI - Signaling Pathways in Inflammation and Anti-inflammatory Therapies. AB - During the past decade, an abundance of new evidence highlighted the importance of inflammation in the development of chronic pathologies such as neurodegeneration, cancer, diabetes, cardiovascular disease and inflammatory bowel disease. However, most of the current therapies do not address the underlying problem and better therapies are urgently needed. A growing number of researchers have discovered various signaling pathways that are associated with the initiation and progression of inflammation. Among different pathways, we will focus on three classical inflammatory pathways: p38 MAPK, IL-6/JAK/STAT3 and PI3K; and a non-classical inflammatory pathway, the Hippo. Recently, the Hippo pathway has been linked to various inflammatory modulators such as FoxO1/3, TNFalpha, IL-6, COX2, HIF-1alpha, AP-1, JAK and STAT. In this review, the molecular mechanisms, associated pathologies and selected drugs (both preclinical and clinical) of these signaling pathways will be summarized. Finally, limitations and potential risks of anti-inflammatory drugs will also be discussed. PMID- 29589536 TI - Cryptic Antimicrobial Peptides: Identification Methods and Current Knowledge of their Immunomodulatory Properties. AB - Cationic antimicrobial peptides (CAMPs), also known as host defence peptides (HDPs), are essential evolutionarily conserved components of innate immunity, constitutively or inducibly expressed in response to invasion by pathogens. In addition to a direct antimicrobial action, they are able to synergistically operate with other defence molecules to combat infection by neutralization of endotoxins, chemokine-like activities, induction of angiogenesis and wound repair. The importance of CAMPs has been highlighted in animal models and supported by observations in patient studies. CAMPs are attractive alternative candidates to antibiotic treatment, because they offer several advantages over the currently used drugs, moreover, knowledge on these peptides, especially regarding the intertwinement between their structure, function and mechanism of action, could be applied in the rational design of antimicrobial/anti inflammatory/wound healing enhancing drugs. CAMPs combat pathogens by targeting bacterial membranes and essential membrane-related functions, and, in some cases, also target intracellular components. Despite differences in their size and sequence, many of them share a net positive charge and fold into amphipathic structures after contact with bacterial surfaces or endotoxins like lipopolysaccharides and lipoteichoic acid. Due to their peculiar mechanism, acquisition of resistance towards these peptides would be difficult for the bacteria. Very interestingly it has been demonstrated that several proteins, including proteins apparently not involved in immunity, can behave as sources of CAMPs hidden in their primary structures and released by the action of host and/or bacterial proteases. The existence of these "cryptic CAMPs" suggests that the panel of antimicrobial peptides present in higher eukaryotes and the variety of functions they perform could be much wider and more complex than previously suspected. This review focuses on source, structure and mechanism of action of cryptic CAMPs, with special attention to their immunomodulatory functions. PMID- 29589537 TI - The Role of Host Defense Peptide Human beta-defensins in the Maintenance of Skin Barriers. AB - The epidermis functions as a first-line defense barrier that protects the body from the external environment. As a chemical hindrance, the epidermis possesses acidic pH, highly organized lipids and various host defense peptides, also known as antimicrobial peptides. Human beta-defensins (hBDs), one of the most important host defense peptide families found in our skin, are well-known for their broad spectrum microbicidal activities. However, there is a growing body of evidence indicating that hBDs also orchestrate several immunomodulatory functions and are the cornerstone that bridges the innate and adaptive immune responses during skin inflammation and infection. Moreover, recent work identified the potential role of hBDs in the regulation and maintenance of the skin barrier function. In this review, we describe the current knowledge concerning the role of hBDs in skin barriers and discuss the potential clinical implications of these peptides in cutaneous biology. Understanding the roles of hBDs in the regulation and maintenance of skin barriers may aid in the development of novel therapeutic strategies for skin conditions where the skin barrier is impaired, such as atopic dermatitis and psoriasis. PMID- 29589538 TI - Antimicrobial peptides for the treatment of pulmonary tuberculosis, allies or foes? AB - Tuberculosis is an ancient disease that has become a serious public health issue in recent years, although increasing incidence has been controlled, deaths caused by Mycobacterium tuberculosis have been accentuated due to the emerging of multi drug resistant strains and the comorbidity with diabetes mellitus and HIV. This situation is threatening the goals of World Health Organization (WHO) to eradicate tuberculosis in 2035. WHO has called for the creation of new drugs as an alternative for the treatment of pulmonary tuberculosis, among the plausible molecules that can be used are the Antimicrobial Peptides (AMPs). These peptides have demonstrated remarkable efficacy to kill mycobacteria in vitro and in vivo in experimental models, nevertheless, these peptides not only have antimicrobial activity but also have a wide variety of functions such as angiogenesis, wound healing, immunomodulation and other well-described roles into the human physiology. Therapeutic strategies for tuberculosis using AMPs must be well thought prior to their clinical use; evaluating comorbidities, family history and risk factors to other diseases, since the wide function of AMPs, they could lead to collateral undesirable effects. PMID- 29589539 TI - Paneth Cells and their Antimicrobials in Intestinal Immunity. AB - Since the initial description of granular-rich small-intestinal crypt-based epithelial cells in 1872, today referred to as Paneth cells, a plethora of recent studies underlined their function in intestinal homeostasis. Paneth cells are evolutionary conserved highly secretory cells that produce antimicrobials to control gut microbial communities. Moreover, Paneth cells emerged as stem cell regulators that translate environmental cues into intestinal epithelial responses. Paneth cell disturbances may instigate intestinal inflammation and provide susceptibility to infection. Altered Paneth cell functions have been associated with a variety of inflammatory disease models and were linked to human intestinal disease processes including inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. This review summarizes our current understanding of Paneth cells and their antimicrobials in health and disease. PMID- 29589540 TI - Lactoferrin and Peptide-derivatives: Antimicrobial Agents with Potential Use in Nonspecific Immunity Modulation. AB - Lactoferrin (Lf) is a conserved cationic non-heme glycoprotein that is part of the innate immune defense system of mammals. Lf is present in colostrum, milk and mucosal sites, and it is also produced by polymorphonuclear neutrophils and secreted at infection sites. Lf and Lf N-terminus peptide-derivatives named lactoferricins (Lfcins) are molecules with microbiostatic and microbicidal action in a wide array of pathogens. In addition, they display regulatory properties on components of nonspecific immunity, including toll-like receptors, proand anti inflammatory cytokines, and reactive oxygen species. Mechanisms explaining the ability of Lf and Lfcins to display both up- and down-modulatory properties on cells are not fully understood but result, in part, from their interactions with membrane receptors that elicit biochemical signal pathways, whereas other receptors enable the nuclear translocation of these molecules for the modulation of target genes. The dual role of Lf and Lfcins as antimicrobials and immunomodulators is of biotechnological and pharmaceutical interest. Native Lf and its peptide-derivatives from human and bovine sources, the recombinant versions of the human protein, and their synthetic peptides have potential application as adjunctive agents in therapies to combat infections caused by multi-resistant bacteria and those caused by fungi, protozoa and viruses, as well as in the prevention and reduction of several types of cancer and response to LPS shock, among other effects. In this review, we summarize the immunomodulatory properties of the unique multifunctional protein Lf and its N-terminus peptides. PMID- 29589541 TI - Antimicrobial Peptides in Human Disease: Therapeutic Approaches. Second of Two Parts. AB - Antimicrobial Peptides (AMPs) are produced by a variety of human immune and non immune cells in health and disease. In virtue of their antimicrobial activity, AMPs have been exploited in human disease and here this aspect will extensively be described. AMPs in comparison to antibiotics possess a larger spectrum of antimicrobial activity without inducing microbial resistance. Therefore, their use in the course of antibiotic-resistant infections is justified. AMP activity in early life, in the airways, in the oral and gastro-enteric system, in the skin and in the female reproductive tract, respectively, will be elucidated. In addition, the use of AMPs in sepsis will be discussed due to the frequency of this pathological condition characterized by multiple organ dysfunctions. Finally, the evidence that AMPs represent valid substitutes of antibiotics will be provided and a series of novel substances able to reinforce the innate immune response in different clinical settings will be discussed. PMID- 29589542 TI - Association Between Drug Burden Index and Functional and Cognitive Function in Patients with Multimorbidity AB - Background: Anticholinergic and sedative drugs are associated with adverse events such as cognitiveand functional impairment in elderly. The Drug Burden Index (DBI) is a measure of an individual's total exposure to anticholinergic and sedative drugs. Objetive: The study aimed to evaluate the association between the total DBI and cognitive and functional impairmentin patients with multimorbidity. Setting: Patients with multimorbidity enrolled in the IMPACTO project. Methods: Cross-sectional observational study. Main outcome measure: The anticholinergic and sedative exposure was calculated using DBI. The Pfeiffer Test(PT) was used for cognitive status and the Barthel Index (BI) for functional status. Results: 336 patients were included (mean age 77.6 +/- 8.7 years, 54.2% men and a mean of 11.5 +/- 3.7 prescribeddrugs). 180 patients (53.6%) exposed to anticholinergic and/or sedative drugs were identified. The median scoreobtained in PT was slightly higher in exposed patients (1 (IQR 0-2) and 2 (IQR 0-4), p = 0.082 in "non-exposed"and "exposed", respectively). The bivariate analysis showed an association [0.544 (95% CI 0.044-1.063, p =0.03)]. The median obtained in the BI analysis was 85.0 (IQR 30.0) and 75.5 (IQR 42.5) p = 0.002, in "nonexposed" and "exposed", respectively. After the adjusted analysis, a relationship was obtained between both the variables [-9,558 (95% CI-15,794; -3,321, p = 0.03)]. Conclusion: Higher DBI is associated with the impairment of functional status and, slightly to the deteriorationof cognitive function in patients with multimorbidity. DBI should be considered in patients with multimorbidityto optimize the pharmacological treatment of a group of special interest due to its vulnerability. PMID- 29589544 TI - Tissue-specific Regulation of Innate Immune Responses by Human Cathelicidin LL 37. AB - Cathelicidins form one of the major families of antimicrobial peptides and have been identified in many vertebrates, including humans. LL-37, the only human member of the cathelicidin family, is detected in most sites of the human body that is normally exposed to microbes, including the epithelial lining of the skin, gastrointestinal tract, genitourinary tract and lungs. This peptide is also expressed by a variety of epithelial cells and immune cells, such as neutrophils, monocytes and mast cells. LL-37 has emerged as a key component of innate immunity due to its direct antimicrobial activity against a broad spectrum of invading pathogens. It also exhibits diverse immunomodulatory functions by activating both pro- and anti-inflammatory mediators; inducing cell migration, proliferation and differentiation; and regulating apoptosis of epithelial cells and neutrophils. Given that the phenotypic and functional properties of immune compartments are different and significantly impacted by the anatomical sites, tissue-specific factors of host origin and microbial communities play important roles in the regulation of LL-37. This review summarizes the expression and biological functions of LL-37 and discusses its significant roles in the innate immune system based on its anatomical distribution. PMID- 29589543 TI - Phage-based Nanomedicines as New Immune Therapeutic Agents for Breast Cancer. AB - Despite years of investigation, breast cancer remains a major cause of death worldwide. Phage display is a powerful molecular method in which peptide and protein libraries can be displayed via genetic fusions on the surface of phages. This approach has tremendous potential for biomedical applications and has already facilitated the discovery of specific antibodies, specific antigens, and peptides with potential roles in the diagnosis and treatment of malignancies including breast cancer. In this review, we discuss the new and the latest advancements in the applications of the phage display technique in the provision of immune therapeutics for breast cancer. PMID- 29589545 TI - A Sweeping Role for MicroRNAs in Neuronal Disease, Vascular Disorders, and as Prognostic Indicators. PMID- 29589546 TI - A review on camptothecin analogs with promising cytotoxic profile. AB - Camptothecin (CPT), obtained from Camptotheca acuminata (Nyssaceae), is a quinoline type of alkaloid. Apart from various traditional uses, it is mainly used as a potential cytotoxic agent acting against a variety of cancer cell lines. Though researches have been continuing for last six decades, still it is a demanding task to design potent and cytotoxic CPTs. Different CPT analogs are synthesized to enhance the cytotoxic potential as well as to increase the pharmacokinetic properties of these analogs. Some of these analogs were proven to be clinically effective in different cancer cell lines. In this article, different CPT analogs have been highlighted extensively to get a detail insight about the structure-property relationships as well as different quantitative structure-activity relationships (QSARs) modeling of these analogs are also discussed. This study may be beneficial for designing newer CPT analogs in future. PMID- 29589547 TI - Implication of B23/nucleophosmin in Viral Infections, Potential Uses of B23/NPM1 Inhibitors as Antiviral Therapy. AB - BACKGROUND: B23/nucleophosmin (B23/NPM1) is an abundant multifunctional protein mainly located in the nucleolus but constantly shuttling between the nucleus and cytosol. As a consequence of its constitutive expression, intracellular dynamics and binding capacities, B23/NPM1 interacts with multiple cellular factors in different cellular compartments, but also with viral proteins from both DNA and RNA viruses. B23/NPM1 influences overall viral replication of viruses like HIV, HBV, HCV, HDV and HPV by playing functional roles in different stages of viral replication including nuclear import, viral genome transcription and assembly, as well as final particle formation. Of note, some virus modify the subcellular localization, stability and/or increases B23/NPM1 expression levels on target cells, probably to foster B23/NPM1 functions in their own replicative cycle. RESULTS: This review summarizes current knowledge concerning the interaction of B23/NPM1 with several viral proteins during relevant human infections. The opportunities and challenges of targeting this well conserved host protein as a potentially new broad antiviral treatment are discussed in detail. Importantly, although initially conceived to treat cancer, a handful of B23/NPM1 inhibitors are currently available to test on viral infection models. CONCLUSIONS: As B23/NPM1 partakes in key steps of viral replication and some viral infections remains as unsolved medical needs, an appealing idea may be the expedite evaluation of B23/NPM1 inhibitors in viral infections. Furthermore, worth to be address is if the up regulation of B23/NPM1 protein levels that follows persistent viral infections may be instrumental to the malignant transformation induced by virus like HBV and HCV. PMID- 29589548 TI - Characterization of Regulatory T-Cells in Multiple Sclerosis Patients Treated with Interferon Beta-1a. AB - BACKGROUND: Regulatory T-Cells (Treg Cells), as one of the immune system components, have been highly effective in the autoimmune diseases prevention, particularly multiple sclerosis (MS). Cytokine-based therapies such as interferon beta-1a (IFN-beta1a) is a common drug in MS treatment; however, its exact mechanisms are insufficiently described. OBJECTIVE: Therefore, the goal of this study was to evaluate the in vivo impact of IFN-beta1a on the Treg Cells in MS. METHODS: In this case-control study, Treg Cells were analysed by flowcytometry in IFN-beta1a-treated relapsing-remitting MS (RRMS) in comparison with new cases of MS and healthy subjects. RESULTS: The frequency of Treg Cells in the IFN-beta1a treated-RRMS was increased compared to the new MS cases (P < 0.05). Furthermore, the MFIs of the CD4 and CD25 in T-Cells were significantly reduced in new cases of MS and IFN-beta1a-treated RRMS than the control subjects (P < 0.05). Additionally, the FoxP3 MFIs in CD4 + CD25 + T-Cells of IFN-beta1a-treated RRMS were significantly lower than the new cases of MS. CONCLUSION: Overall, the present study indicated that IFN-beta1a as an immunomodulatory drug led to an enhancement in Treg Cells population without CD4, CD25, and FoxP3 molecules upregulation in Treg Cells. PMID- 29589549 TI - Effect of Laparoscopic Sleeve Gastrectomy on Thyroid Hormones in Euthyroid Obese Patients. AB - INTRODUCTION: In obese patients, the incidences of several thyroid disorders have increased in comparison to the general population. This study is aimed to investigate the effect of laparoscopic sleeve gastrectomy (LSG) on thyroid function tests in obese patients. METHODS: The patient files of 186 individuals who underwent laparoscopic sleeve gastrectomy surgery were examined retrospectively. Forty-nine females and 29 males comprising a total of 78 patients were included in the study. The routine physical examination findings and laboratory parameters recorded preoperatively were compared with their counterparts obtained in the postoperative sixth month. RESULTS: The mean preoperative body mass index (BMI) levels of the patients in the study was calculated as 46.91 kg/m2, whereas the mean BMI in the postoperative sixth month was 30.35 kg/m2 (p<0.001). Prior to the sleeve gastrectomy, the mean thyroid stimulating hormone (TSH) level of the patients was 2.53 +/-2.06 uIU/mL; however, a significant reduction was observed in the mean TSH level during the postoperative sixth month, which was calculated as 1.77 +/-1.12 uIU/mL (p=0.015). The mean free T4 level was 1.18+/-0.1 ng/dL in the preoperative period, but this increased to 1.22 +/-0.24 ng/dL postoperatively, an insignificant change. The decrease in the TSH levels after the LSG was determined not to be correlated with the decrease in body weight. CONCLUSION: The results of our study demonstrate that the levels of TSH decreased significantly in patients who underwent LSG and that the decrease was independent of the changes in BMI. PMID- 29589550 TI - The Effect of Denatured Flagellin on Toll-Like Receptor-5 (TLR-5) in Mice. AB - BACKGROUND: Previous studies have demonstrated that flagellin, a component of bacterial flagella, engages Toll-Like receptor 5 (TLR-5) causing the activation of the Myeloid Differentiation Factor-88 (MYD-88) pathway that leads to the production of pro-inflammatory cytokines including Tumor Necrosis Factor-alpha (TNF-alpha) and Interleukin-12 (IL-12). In physiological levels, cytokines can aid in protection against infectious agents. However, excessive production of cytokines can lead to septic shock during sepsis. OBJECTIVE: In this study, we aimed at investigating the effect of denatured flagellin on hindering the effects induced by intact flagellin or flagellated Pseudomonas aeruginosa on the Toll Like Receptor-5 (TLR-5) in mice. METHODS: Mouse mononuclear cells (MNCs) were cultured with intact flagellin, heat-denatured flagellin, TLR-5 antagonist, Pseudomonas aeruginosa, and TLR-4 antagonist each alone or in combinations. Supernatants were collected at 4 hours post incubation to assess the levels of IL 12 and TNF-alpha by Enzyme-Linked ImmunoAssay (ELISA). Furthermore, groups of BALB/c mice were injected intraperitoneally (IP) with Pseudomonas aeruginosa, LPS RS, intact flagellin, and denatured flagellin, each alone or in different combinations. Serum levels of IL-12 and TNF-alpha were measured at 2, 4, and 6 hours post injections of Pseudomonas aeruginosa or intact flagellin. RESULTS: Pretreatment with denatured flagellin significantly reduced the amount of TNF alpha and IL-12 produced both in vitro and in vivo by intact flagellin or Pseudomonas aeruginosa. CONCLUSION: Denatured flagellin suppressed the production of the pro-inflammatory cytokines induced by intact flagellin or Pseudomonas aeruginosa both in vitro and in vivo, probably by blocking TLR5. Denatured flagellin might be considered as an anti-septic shock agent. PMID- 29589551 TI - Recent Patents on Polymeric Nanoparticles for Cancer Therapy. AB - BACKGROUND: Cancer is a major problem which has claimed so many lives throughout the world. Although a number of resources have been utilized for the development of cancer therapeutics, no effective cure has been found so far. OBJECTIVE: Therefore, the need for looking at evolving technologies has become very important to get a solution to this problem. Among these, nanotechnology has got so much popularity and became feasible in the past few years. Nanotechnology is presently used as the most preferable drug delivery platform for cancer therapy. METHOD: A variety of nanomaterials based on lipid, polymer, metal or magnet have been developed for enhancement of the efficiency of current treatment. RESULTS: Recently, polymeric-nanoparticles have been exploited as a carrier of many drug substances for invasive and non-invasive routes of delivery. CONCLUSION: In this manuscript, the authors have reviewed different aspects of nanoparticles, recent patents and research issues related to cancer. PMID- 29589552 TI - Evaluation and Management of Children with Thyrotoxicosis. AB - BACKGROUND: Uncontrolled thyrotoxicosis, especially in early infancy, may cause irreversible damage to the central nervous system as well as profound effects on the function of many organs. Thyrotoxicosis has multiple etiologies and treatment depends on the underlying etiology. An accurate diagnosis is essential so that appropriate treatment can be initiated without undue delay. OBJECTIVE: To review in depth the evaluation, diagnosis, and treatment of children with thyrotoxicosis. METHODS: A PubMed search was completed in Clinical Queries using the key terms "thyrotoxicosis" and "hyperthyroidism". The search strategy included meta-analysis, randomized controlled trials, clinical trials, observational studies, and reviews. Patents were searched using the key terms "thyrotoxicosis" and "hyperthyroidism" from www.freepatentsonline.com and www.google.com/patents. RESULTS: Graves' disease accounts for approximately 96% of pediatric cases of thyrotoxicosis. Other causes include Hashitoxicosis, toxic adenoma, toxic multinodular goiter, subacute granulomatous thyroiditis, acute suppurative thyroiditis, pituitary thyroid-stimulating hormone-secreting adenoma, pituitary thyroid hormone resistance, iodine-induced thyrotoxicosis, and drug induced thyrotoxicosis. Familiarity of the clinical features would allow prompt diagnosis and institution of treatment. The underlying cause of thyrotoxicosis should be treated if possible. Treatment options for Graves' disease include antithyroid medications, radioiodine therapy, and surgery. Recent patents related to the management of thyrotoxicosis are discussed. CONCLUSION: Currently, antithyroid medications are considered to be the initial treatment of choice for Graves' disease in the pediatric age group. Radioactive iodine treatment is generally used for children with poor compliance with antithyroid medications, children not in remission after 1 to 2 years of antithyroid medications, and children with a major adverse effect while receiving an antithyroid medication. Total or near-total thyroidectomy should be considered in children younger than 5 years of age who do not respond to or experience a major adverse effect to antithyroid medications. Surgery should also be considered in those with very large goiter, severe ophthalmopathy, pregnancy, persistent hyperthyroidism in spite of treatment with antithyroid medications and radioactive iodine, and personal preference. PMID- 29589553 TI - Young Children Talking about Food and Health. AB - BACKGROUND: Limited patents have explored young children's understanding of the connection between food and health. This qualitative study aimed to narrow this gap by investigating young children's health conceptions. METHODS: Seventy-two children, 5 to 7 years of age, participated in this study. Two instruments, the demographic survey and child interview survey, were used to collect data. Data were analyzed following the processes of conducting initial coding, specifying categories, and combining categories to develop themes. RESULTS: Children in this age group had certain knowledge about five food categories: Diary, meat, grain, fruit, and vegetables. They believed that food from these five categories were good for them and would make them strong; they also believed that sweets and salty foods were unhealthy, yet many of them preferred sweets and listed them as top snack choices. These children demonstrated awareness of complex nutritional terms such as vitamins, fiber, and protein yet misconceptions became evident when were asked to identify overall health effects of mixed dishes for which various components were not easily recognizable. CONCLUSION: This study provides new insights into children's understanding about food, nutrition, and health that can impact future education endeavors. Findings from this study can be helpful to inform educators about the development of nutritional education curricula specifically targeting nutritional values regarding foods being processed in different ways. PMID- 29589554 TI - Sparse Tensor Decomposition for Haplotype Assembly of Diploids and Polyploids. AB - BACKGROUND: Haplotype assembly is the task of reconstructing haplotypes of an individual from a mixture of sequenced chromosome fragments. Haplotype information enables studies of the effects of genetic variations on an organism's phenotype. Most of the mathematical formulations of haplotype assembly are known to be NP-hard and haplotype assembly becomes even more challenging as the sequencing technology advances and the length of the paired-end reads and inserts increases. Assembly of haplotypes polyploid organisms is considerably more difficult than in the case of diploids. Hence, scalable and accurate schemes with provable performance are desired for haplotype assembly of both diploid and polyploid organisms. RESULTS: We propose a framework that formulates haplotype assembly from sequencing data as a sparse tensor decomposition. We cast the problem as that of decomposing a tensor having special structural constraints and missing a large fraction of its entries into a product of two factors, U and [Formula: see text]; tensor [Formula: see text] reveals haplotype information while U is a sparse matrix encoding the origin of erroneous sequencing reads. An algorithm, AltHap, which reconstructs haplotypes of either diploid or polyploid organisms by iteratively solving this decomposition problem is proposed. The performance and convergence properties of AltHap are theoretically analyzed and, in doing so, guarantees on the achievable minimum error correction scores and correct phasing rate are established. The developed framework is applicable to diploid, biallelic and polyallelic polyploid species. The code for AltHap is freely available from https://github.com/realabolfazl/AltHap . CONCLUSION: AltHap was tested in a number of different scenarios and was shown to compare favorably to state-of-the-art methods in applications to haplotype assembly of diploids, and significantly outperforms existing techniques when applied to haplotype assembly of polyploids. PMID- 29589555 TI - Bayesian graphical models for computational network biology. AB - BACKGROUND: Computational network biology is an emerging interdisciplinary research area. Among many other network approaches, probabilistic graphical models provide a comprehensive probabilistic characterization of interaction patterns between molecules and the associated uncertainties. RESULTS: In this article, we first review graphical models, including directed, undirected, and reciprocal graphs (RG), with an emphasis on the RG models that are curiously under-utilized in biostatistics and bioinformatics literature. RG's strictly contain chain graphs as a special case and are suitable to model reciprocal causality such as feedback mechanism in molecular networks. We then extend the RG approach to modeling molecular networks by integrating DNA-, RNA- and protein level data. We apply the extended RG method to The Cancer Genome Atlas multi platform ovarian cancer data and reveal several interesting findings. CONCLUSIONS: This study aims to review the basics of different probabilistic graphical models as well as recent development in RG approaches for network modeling. The extension presented in this paper provides a principled and efficient way of integrating DNA copy number, DNA methylation, mRNA gene expression and protein expression. PMID- 29589556 TI - A Bayesian approach to determine the composition of heterogeneous cancer tissue. AB - BACKGROUND: Cancer Tissue Heterogeneity is an important consideration in cancer research as it can give insights into the causes and progression of cancer. It is known to play a significant role in cancer cell survival, growth and metastasis. Determining the compositional breakup of a heterogeneous cancer tissue can also help address the therapeutic challenges posed by heterogeneity. This necessitates a low cost, scalable algorithm to address the challenge of accurate estimation of the composition of a heterogeneous cancer tissue. METHODS: In this paper, we propose an algorithm to tackle this problem by utilizing the data of accurate, but high cost, single cell line cell-by-cell observation methods in low cost aggregate observation method for heterogeneous cancer cell mixtures to obtain their composition in a Bayesian framework. RESULTS: The algorithm is analyzed and validated using synthetic data and experimental data. The experimental data is obtained from mixtures of three separate human cancer cell lines, HCT116 (Colorectal carcinoma), A2058 (Melanoma) and SW480 (Colorectal carcinoma). CONCLUSION: The algorithm provides a low cost framework to determine the composition of heterogeneous cancer tissue which is a crucial aspect in cancer research. PMID- 29589557 TI - Selected research articles from the 2017 International Workshop on Computational Network Biology: Modeling, Analysis, and Control (CNB-MAC). PMID- 29589558 TI - Heuristic algorithms for feature selection under Bayesian models with block diagonal covariance structure. AB - BACKGROUND: Many bioinformatics studies aim to identify markers, or features, that can be used to discriminate between distinct groups. In problems where strong individual markers are not available, or where interactions between gene products are of primary interest, it may be necessary to consider combinations of features as a marker family. To this end, recent work proposes a hierarchical Bayesian framework for feature selection that places a prior on the set of features we wish to select and on the label-conditioned feature distribution. While an analytical posterior under Gaussian models with block covariance structures is available, the optimal feature selection algorithm for this model remains intractable since it requires evaluating the posterior over the space of all possible covariance block structures and feature-block assignments. To address this computational barrier, in prior work we proposed a simple suboptimal algorithm, 2MNC-Robust, with robust performance across the space of block structures. Here, we present three new heuristic feature selection algorithms. RESULTS: The proposed algorithms outperform 2MNC-Robust and many other popular feature selection algorithms on synthetic data. In addition, enrichment analysis on real breast cancer, colon cancer, and Leukemia data indicates they also output many of the genes and pathways linked to the cancers under study. CONCLUSIONS: Bayesian feature selection is a promising framework for small-sample high dimensional data, in particular biomarker discovery applications. When applied to cancer data these algorithms outputted many genes already shown to be involved in cancer as well as potentially new biomarkers. Furthermore, one of the proposed algorithms, SPM, outputs blocks of heavily correlated genes, particularly useful for studying gene interactions and gene networks. PMID- 29589559 TI - Investigation of model stacking for drug sensitivity prediction. AB - BACKGROUND: A significant problem in precision medicine is the prediction of drug sensitivity for individual cancer cell lines. Predictive models such as Random Forests have shown promising performance while predicting from individual genomic features such as gene expressions. However, accessibility of various other forms of data types including information on multiple tested drugs necessitates the examination of designing predictive models incorporating the various data types. RESULTS: We explore the predictive performance of model stacking and the effect of stacking on the predictive bias and squared error. In addition we discuss the analytical underpinnings supporting the advantages of stacking in reducing squared error and inherent bias of random forests in prediction of outliers. The framework is tested on a setup including gene expression, drug target, physical properties and drug response information for a set of drugs and cell lines. CONCLUSION: The performance of individual and stacked models are compared. We note that stacking models built on two heterogeneous datasets provide superior performance to stacking different models built on the same dataset. It is also noted that stacking provides a noticeable reduction in the bias of our predictors when the dominant eigenvalue of the principle axis of variation in the residuals is significantly higher than the remaining eigenvalues. PMID- 29589560 TI - Simulating variance heterogeneity in quantitative genome wide association studies. AB - BACKGROUND: Analyzing Variance heterogeneity in genome wide association studies (vGWAS) is an emerging approach for detecting genetic loci involved in gene-gene and gene-environment interactions. vGWAS analysis detects variability in phenotype values across genotypes, as opposed to typical GWAS analysis, which detects variations in the mean phenotype value. RESULTS: A handful of vGWAS analysis methods have been recently introduced in the literature. However, very little work has been done for evaluating these methods. To enable the development of better vGWAS analysis methods, this work presents the first quantitative vGWAS simulation procedure. To that end, we describe the mathematical framework and algorithm for generating quantitative vGWAS phenotype data from genotype profiles. Our simulation model accounts for both haploid and diploid genotypes under different modes of dominance. Our model is also able to simulate any number of genetic loci causing mean and variance heterogeneity. CONCLUSIONS: We demonstrate the utility of our simulation procedure through generating a variety of genetic loci types to evaluate common GWAS and vGWAS analysis methods. The results of this evaluation highlight the challenges current tools face in detecting GWAS and vGWAS loci. PMID- 29589561 TI - Feature selection with interactions in logistic regression models using multivariate synergies for a GWAS application. AB - BACKGROUND: Genotype-phenotype association has been one of the long-standing problems in bioinformatics. Identifying both the marginal and epistatic effects among genetic markers, such as Single Nucleotide Polymorphisms (SNPs), has been extensively integrated in Genome-Wide Association Studies (GWAS) to help derive "causal" genetic risk factors and their interactions, which play critical roles in life and disease systems. Identifying "synergistic" interactions with respect to the outcome of interest can help accurate phenotypic prediction and understand the underlying mechanism of system behavior. Many statistical measures for estimating synergistic interactions have been proposed in the literature for such a purpose. However, except for empirical performance, there is still no theoretical analysis on the power and limitation of these synergistic interaction measures. RESULTS: In this paper, it is shown that the existing information theoretic multivariate synergy depends on a small subset of the interaction parameters in the model, sometimes on only one interaction parameter. In addition, an adjusted version of multivariate synergy is proposed as a new measure to estimate the interactive effects, with experiments conducted over both simulated data sets and a real-world GWAS data set to show the effectiveness. CONCLUSIONS: We provide rigorous theoretical analysis and empirical evidence on why the information-theoretic multivariate synergy helps with identifying genetic risk factors via synergistic interactions. We further establish the rigorous sample complexity analysis on detecting interactive effects, confirmed by both simulated and real-world data sets. PMID- 29589562 TI - Qcorp: an annotated classification corpus of Chinese health questions. AB - BACKGROUND: Health question-answering (QA) systems have become a typical application scenario of Artificial Intelligent (AI). An annotated question corpus is prerequisite for training machines to understand health information needs of users. Thus, we aimed to develop an annotated classification corpus of Chinese health questions (Qcorp) and make it openly accessible. METHODS: We developed a two-layered classification schema and corresponding annotation rules on basis of our previous work. Using the schema, we annotated 5000 questions that were randomly selected from 5 Chinese health websites within 6 broad sections. 8 annotators participated in the annotation task, and the inter-annotator agreement was evaluated to ensure the corpus quality. Furthermore, the distribution and relationship of the annotated tags were measured by descriptive statistics and social network map. RESULTS: The questions were annotated using 7101 tags that covers 29 topic categories in the two-layered schema. In our released corpus, the distribution of questions on the top-layered categories was treatment of 64.22%, diagnosis of 37.14%, epidemiology of 14.96%, healthy lifestyle of 10.38%, and health provider choice of 4.54% respectively. Both the annotated health questions and annotation schema were openly accessible on the Qcorp website. Users can download the annotated Chinese questions in CSV, XML, and HTML format. CONCLUSIONS: We developed a Chinese health question corpus including 5000 manually annotated questions. It is openly accessible and would contribute to the intelligent health QA system development. PMID- 29589563 TI - A pattern learning-based method for temporal expression extraction and normalization from multi-lingual heterogeneous clinical texts. AB - BACKGROUND: Temporal expression extraction and normalization is a fundamental and essential step in clinical text processing and analyzing. Though a variety of commonly used NLP tools are available for medical temporal information extraction, few work is satisfactory for multi-lingual heterogeneous clinical texts. METHODS: A novel method called TEER is proposed for both multi-lingual temporal expression extraction and normalization from various types of narrative clinical texts including clinical data requests, clinical notes, and clinical trial summaries. TEER is characterized as temporal feature summarization, heuristic rule generation, and automatic pattern learning. By representing a temporal expression as a triple , TEER identifies temporal mentions M, assigns type attributes A to M, and normalizes the values of M into formal representations N. RESULTS: Based on two heterogeneous clinical text datasets: 400 actual clinical requests in English and 1459 clinical discharge summaries in Chinese. TEER was compared with six state-of-the-art baselines. The results showed that TEER achieved a precision of 0.948 and a recall of 0.877 on the English clinical requests, while a precision of 0.941 and a recall of 0.932 on the Chinese discharge summaries. CONCLUSIONS: An automated method TEER for multi lingual temporal expression extraction was presented. Based on the two datasets containing heterogeneous clinical texts, the comparison results demonstrated the effectiveness of the TEER method in multi-lingual temporal expression extraction from heterogeneous narrative clinical texts. PMID- 29589564 TI - Intrinsically Bayesian robust classifier for single-cell gene expression trajectories in gene regulatory networks. AB - BACKGROUND: Expression-based phenotype classification using either microarray or RNA-Seq measurements suffers from a lack of specificity because pathway timing is not revealed and expressions are averaged across groups of cells. This paper studies expression-based classification under the assumption that single-cell measurements are sampled at a sufficient rate to detect regulatory timing. Thus, observations are expression trajectories. In effect, classification is performed on data generated by an underlying gene regulatory network. RESULTS: Network regulation is modeled via a Boolean network with perturbation, regulation not fully determined owing to inherent biological randomness. The binary assumption is not critical because the resulting Markov chain characterizes expression trajectories. We assume a partially known Gaussian observation model belonging to an uncertainty class of models. We derive the intrinsically Bayesian robust classifier to discriminate between wild-type and mutated networks based on expression trajectories. The classifier minimizes the expected error across the uncertainty class relative to the prior distribution. We test it using a mammalian cell-cycle model, discriminating between the normal network and one in which gene p27 is mutated, thereby producing a cancerous phenotype. Tests examine all model aspects, including trajectory length, perturbation probability, and the hyperparameters governing the prior distribution over the uncertainty class. CONCLUSIONS: Simulations show the rates at which the expected error is diminished by smaller perturbation probability, longer trajectories, and hyperparameters that tighten the prior distribution relative to the unknown true network. For average-expression measurement, methods have been proposed to obtain prior distributions. These should be extended to the more mathematically difficult, but more informative, expression trajectories. PMID- 29589565 TI - Detangling PPI networks to uncover functionally meaningful clusters. AB - BACKGROUND: Decomposing a protein-protein interaction network (PPI network) into non-overlapping clusters or communities, sometimes called "network modules," is an important way to explore functional roles of sets of genes. When the method to accomplish this decomposition is solely based on purely graph-theoretic measures of the interconnection structure of the network, this is often called unsupervised clustering or community detection. In this study, we compare unsupervised computational methods for decomposing a PPI network into non overlapping modules. A method is preferred if it results in a large proportion of nodes being assigned to functionally meaningful modules, as measured by functional enrichment over terms from the Gene Ontology (GO). RESULTS: We compare the performance of three popular community detection algorithms with the same algorithms run after the network is pre-processed by removing and reweighting based on the diffusion state distance (DSD) between pairs of nodes in the network. We call this "detangling" the network. In almost all cases, we find that detangling the network based on the DSD distance reweighting provides more meaningful clusters. CONCLUSIONS: Re-embedding using the DSD distance metric, before applying standard community detection algorithms, can assist in uncovering GO functionally enriched clusters in the yeast PPI network.

AB - BACKGROUND: The integration of gene expression profiles (GEPs) and large-scale biological networks derived from pathways databases is a subject which is being widely explored. Existing methods are based on network distance measures among significantly measured species. Only a small number of them include the directionality and underlying logic existing in biological networks. In this study we approach the GEP-networks integration problem by considering the network logic, however our approach does not require a prior species selection according to their gene expression level. RESULTS: We start by modeling the biological network representing its underlying logic using Logic Programming. This model points to reachable network discrete states that maximize a notion of harmony between the molecular species active or inactive possible states and the directionality of the pathways reactions according to their activator or inhibitor control role. Only then, we confront these network states with the GEP. From this confrontation independent graph components are derived, each of them related to a fixed and optimal assignment of active or inactive states. These components allow us to decompose a large-scale network into subgraphs and their molecular species state assignments have different degrees of similarity when compared to the same GEP. We apply our method to study the set of possible states derived from a subgraph from the NCI-PID Pathway Interaction Database. This graph links Multiple Myeloma (MM) genes to known receptors for this blood cancer. CONCLUSION: We discover that the NCI-PID MM graph had 15 independent components, and when confronted to 611 MM GEPs, we find 1 component as being more specific to represent the difference between cancer and healthy profiles.

AB - BACKGROUND: Acute kidney injury (AKI), characterized by abrupt deterioration of renal function, is a common clinical event among hospitalized patients and it is associated with high morbidity and mortality. AKI is defined in three stages with stage-3 being the most severe phase which is irreversible. It is important to effectively discover the true risk factors in order to identify high-risk AKI patients and allow better targeting of tailored interventions. However, Stage-3 AKI patients are very rare (only 0.2% of AKI patients) with a large scale of features available in EHR (1917 potential risk features), yielding a scenario unfeasible for any correlation-based feature selection or modeling method. This study aims to discover the key factors and improve the detection of Stage-3 AKI. METHODS: A causal discovery method (McDSL) is adopted for causal discovery to infer true causal relationship between information buried in EHR (such as medication, diagnosis, laboratory tests, comorbidities and etc.) and Stage-3 AKI risk. The research approach comprised two major phases: data collection, and causal discovery. The first phase is propose to collect the data from HER (includes 358 encounters and 891 risk factors). Finally, McDSL is employed to discover the causal risk factors of Stage-3 AKI, and five well-known machine learning models are built for predicting Stage-3 AKI with 10-fold cross validation (predictive accuracy were measured by AUC, precision, recall and F score). RESULTS: McDSL is useful for further research of EHR. It is able to discover four causal features, all selected features are medications that are modifiable. The latest research of machine learning is employed to compare the performance of prediction, and the experimental result has verified the selected features are pivotal. CONCLUSIONS: The features selected by McDSL, which enable us to achieve significant dimension reduction without sacrificing prediction accuracy, suggesting potential clinical use such as helping physicians develop better prevention and treatment strategies. PMID- 29589568 TI - Heterogeneous network propagation for herb target identification. AB - BACKGROUND: Identifying targets of herbs is a primary step for investigating pharmacological mechanisms of herbal drugs in Traditional Chinese medicine (TCM). Experimental targets identification of herbs is a difficult and time-consuming work. Computational method for identifying herb targets is an efficient approach. However, how to make full use of heterogeneous network data about herbs and targets to improve the performance of herb targets prediction is still a dilemma. METHODS: In our study, a random walk algorithm on the heterogeneous herb-target network (named heNetRW) has been proposed to identify protein targets of herbs. By building a heterogeneous herb-target network involving herbs, targets and their interactions and simulating random walk algorithm on the network, the candidate targets of the given herb can be predicted. RESULTS: The experimental results on large-scale dataset showed that heNetRW had higher performance of targets prediction than PRINCE (improved F1-score by 0.08 and Hit@1 by 21.34% in one validation setting, and improved F1-score by 0.54 and Hit@1 by 69.08% in the other validation setting). Furthermore, we evaluated novel candidate targets of two herbs (rhizoma coptidis and turmeric), which showed our approach could generate potential targets that are valuable for further experimental investigations. CONCLUSIONS: Compared with PRINCE algorithm, heNetRW algorithm can fuse more known information (such as, known herb-target associations and pathway-based similarities of protein pairs) to improve prediction performance. Experimental results also indicated heNetRW had higher performance than PRINCE. The prediction results not only can be used to guide the selection of candidate targets of herbs, but also help to reveal the molecule mechanisms of herbal drugs. PMID- 29589569 TI - A bibliometric analysis of natural language processing in medical research. AB - BACKGROUND: Natural language processing (NLP) has become an increasingly significant role in advancing medicine. Rich research achievements of NLP methods and applications for medical information processing are available. It is of great significance to conduct a deep analysis to understand the recent development of NLP-empowered medical research field. However, limited study examining the research status of this field could be found. Therefore, this study aims to quantitatively assess the academic output of NLP in medical research field. METHODS: We conducted a bibliometric analysis on NLP-empowered medical research publications retrieved from PubMed in the period 2007-2016. The analysis focused on three aspects. Firstly, the literature distribution characteristics were obtained with a statistics analysis method. Secondly, a network analysis method was used to reveal scientific collaboration relations. Finally, thematic discovery and evolution was reflected using an affinity propagation clustering method. RESULTS: There were 1405 NLP-empowered medical research publications published during the 10 years with an average annual growth rate of 18.39%. 10 most productive publication sources together contributed more than 50% of the total publications. The USA had the highest number of publications. A moderately significant correlation between country's publications and GDP per capita was revealed. Denny, Joshua C was the most productive author. Mayo Clinic was the most productive affiliation. The annual co-affiliation and co-country rates reached 64.04% and 15.79% in 2016, respectively. 10 main great thematic areas were identified including Computational biology, Terminology mining, Information extraction, Text classification, Social medium as data source, Information retrieval, etc. CONCLUSIONS: A bibliometric analysis of NLP-empowered medical research publications for uncovering the recent research status is presented. The results can assist relevant researchers, especially newcomers in understanding the research development systematically, seeking scientific cooperation partners, optimizing research topic choices and monitoring new scientific or technological activities.

AB - BACKGROUND: De-identification is the first step to use these records for data processing or further medical investigations in electronic medical records. Consequently, a reliable automated de-identification system would be of high value. METHODS: In this paper, a method of combining text skeleton and recurrent neural network is proposed to solve the problem of de-identification. Text skeleton is the general structure of a medical record, which can help neural networks to learn better. RESULTS: We evaluated our method on three datasets involving two English datasets from i2b2 de-identification challenge and a Chinese dataset we annotated. Empirical results show that the text skeleton based method we proposed can help the network to recognize protected health information. CONCLUSIONS: The comparison between our method and state-of-the-art frameworks indicates that our method achieves high performance on the problem of medical record de-identification. PMID- 29589572 TI - An openEHR based approach to improve the semantic interoperability of clinical data registry. AB - BACKGROUND: Clinical data registry is designed to collect and manage information about the practices and outcomes of a patient population for improving the quality and safety of care and facilitating novel researches. Semantic interoperability is a challenge when integrating the data from more than one clinical data registry. The openEHR approach can represent the information and knowledge semantics by multi-level modeling, and it advocates the use of collaborative modeling to facilitate reusing existing archetypes with consistent semantics so as to be a potential solution to improve the semantic interoperability. METHODS: This paper proposed an openEHR based approach to improve the semantic interoperability of clinical data registry. The approach consists of five steps: clinical data registry meta-information collection, data element definition, archetype modeling, template editing, and implementation. Through collaborative modeling and maximum reusing of existing archetype at the archetype modeling step, the approach can improve semantic interoperability. To verify the feasibility of the approach, this paper conducted a case study of building a Coronary Computed Tomography Angiography (CCTA) registry that can interoperate with an existing Electronic Health Record (EHR) system. RESULTS: The CCTA registry includes 183 data elements, which involves 20 archetypes. A total number of 45 CCTA data elements and EHR data elements have semantic overlap. Among them, 38 (84%) CCTA data elements can be found in the 10 reused EHR archetypes. These corresponding clinical data can be collected from the EHR system directly without transformation. The other 7 (16%) CCTA data elements correspond to one coarse-grained EHR data elements, and these clinical data can be collected with mapping rules. The results show that the approach can improve semantic interoperability of clinical data registry. CONCLUSIONS: Using an openEHR based approach to develop clinical data registry can improve the semantic interoperability. Meanwhile, some challenges for broader semantic interoperability are identified, including domain experts' involvement, archetype sharing and reusing, and archetype semantic mapping. Collaborative modeling, easy to-use tools, and semantic relationship establishment are potential solutions for these challenges. This study provides some experience and insight about clinical modeling and clinical data registry development.

AB - Transmission electron microscopy (TEM) with low-energy electrons has been recognized as an important addition to the family of electron microscopies as it may avoid knock-on damage and increase the contrast of weakly scattering objects. Scanning electron microscopes (SEMs) are well suited for low-energy electron microscopy with maximum electron energies of 30 keV, but they are mainly used for topography imaging of bulk samples. Implementation of a scanning transmission electron microscopy (STEM) detector and a charge-coupled-device camera for the acquisition of on-axis transmission electron diffraction (TED) patterns, in combination with recent resolution improvements, make SEMs highly interesting for structure analysis of some electron-transparent specimens which are traditionally investigated by TEM. A new aspect is correlative SEM, STEM, and TED imaging from the same specimen region in a SEM which leads to a wealth of information. Simultaneous image acquisition gives information on surface topography, inner structure including crystal defects and qualitative material contrast. Lattice fringe resolution is obtained in bright-field STEM imaging. The benefits of correlative SEM/STEM/TED imaging in a SEM are exemplified by structure analyses from representative sample classes such as nanoparticulates and bulk materials.

AB - SummaryThe aim of this study was to describe the effect of temperature on the fertilization, early developmental stages, and survival rate of two Neotropical catfishes Pimelodus maculatus and Pseudopimelodus mangurus. After fertilization, the eggs were incubated at 22 degrees C, 26 degrees C, and 30 degrees C, which resulted in fertilization rates of 96.95 +/- 1.79%, 98.74 +/- 0.76%, and 98.44 +/ 0.19% for P. maculatus and 96.10 +/- 1.58%, 98.00 +/- 0.63%, and 94.60 +/- 2.09% for P. mangurus, respectively. For P. maculatus, hatching occurred after 22 h 30 min post-fertilization at 22 degrees C, 16 h 30 min at 26 degrees C, and 11 h 20 min at 30 degrees C, and the hatching rates were 43.87 +/- 7,46%, 57.57 +/- 17.49%, and 53.63 +/- 16.27%, respectively. For P. mangurus, hatching occurred after 28 h 30 min post-fertilization at 22 degrees C and 17 h 30 min at 26 degrees C with respective hatching rates of 45.4 +/- 21.02% and 68.1 +/- 12.67%. For this species, all embryos incubated at 30 degrees C died before hatching. Additionally, for P. maculatus, the larvae from the lower (22 degrees C) and higher temperatures (30 degrees C) presented increased abnormality rates, as observed in the head, tail and yolk regions. The lowest abnormality rate was detected at 26 degrees C, which was considered the optimal incubation temperature for both species. The developed protocol enables the manipulation of embryonic development, which is important for the application of reproductive biotechniques, including chimerism and chromosome-set manipulation. The data obtained here are also important for the surrogate propagation of this species as P. mangurus was recently categorized as an endangered fish species. PMID- 29589577 TI - Hepatitis E virus (HEV) in Scotland: evidence of recent increase in viral circulation in humans. AB - BackgroundPrevious studies showed low levels of circulating hepatitis E virus (HEV) in Scotland. We aimed to reassess current Scottish HEV epidemiology. Methods: Blood donor samples from five Scottish blood centres, the minipools for routine HEV screening and liver transplant recipients were tested for HEV antibodies and RNA to determine seroprevalence and viraemia. Blood donor data were compared with results from previous studies covering 2004-08. Notified laboratory-confirmed hepatitis E cases (2009-16) were extracted from national surveillance data. Viraemic samples from blood donors (2016) and chronic hepatitis E transplant patients (2014-16) were sequenced. Results: Anti-HEV IgG seroprevalence varied geographically and was highest in Edinburgh where it increased from 4.5% in 2004-08) to 9.3% in 2014-15 (p = 0.001). It was most marked in donors < 35 years. HEV RNA was found in 1:2,481 donors, compared with 1:14,520 in 2011. Notified laboratory-confirmed cases increased by a factor of 15 between 2011 and 2016, from 13 to 206. In 2011-13, 1 of 329 transplant recipients tested positive for acute HEV, compared with six cases of chronic infection during 2014-16. Of 10 sequenced viraemic donors eight and all six patients were infected with genotype 3 clade 1 virus, common in European pigs. Conclusions: The seroprevalence, number of viraemic donors and numbers of notified laboratory confirmed cases of HEV in Scotland have all recently increased. The causes of this change are unknown, but need further investigation. Clinicians in Scotland, particularly those caring for immunocompromised patients, should have a low threshold for testing for HEV. PMID- 29589578 TI - Universal screening for latent and active tuberculosis (TB) in asylum seeking children, Bochum and Hamburg, Germany, September 2015 to November 2016. AB - BackgroundIn Germany, the incidence of tuberculosis (TB) in children has been on the rise since 2009. High numbers of foreign-born asylum seekers have contributed considerably to the disease burden. Therefore, effective screening strategies for latent TB infection (LTBI) and active TB in asylum seeking children are needed. Aim: Our aim was to investigate the prevalence of LTBI and active TB in asylum seeking children up to 15 years of age in two geographic regions in Germany. Methods: Screening for TB was performed in children in asylum seeker reception centres by tuberculin skin test (TST) or interferon gamma release assay (IGRA). Children with positive results were evaluated for active TB. Additionally, country of origin, sex, travel time, TB symptoms, TB contact and Bacille Calmette Guerin (BCG) vaccination status were registered. Results: Of 968 screened children 66 (6.8%) had TB infection (58 LTBI, 8 active TB). LTBI prevalence was similar in children from high (Afghanistan) and low (Syria) incidence countries (8.7% vs 6.4%). There were no differences regarding sex, age or travel time between infected and non-infected children. Children under the age of 6 years were at higher risk of progression to active TB (19% vs 2% respectively, p=0,07). Most children (7/8) with active TB were asymptomatic at the time of diagnosis. None of the children had been knowingly exposed to TB. Conclusions: Asylum seeking children from high and low incidence countries are both at risk of developing LTBI or active TB. Universal TB screening for all asylum seeking children should be considered. PMID- 29589580 TI - Challenging the future.... PMID- 29589581 TI - Hoje e o primeiro dia do resto da minha vida...

PMID- 29589579 TI - Field investigation with real-time virus genetic characterisation support of a cluster of Ebola virus disease cases in Dubreka, Guinea, April to June 2015. AB - On 11 May 2015, the Dubreka prefecture, Guinea, reported nine laboratory confirmed cases of Ebola virus disease (EVD). None could be epidemiologically linked to cases previously reported in the prefecture. We describe the epidemiological and molecular investigations of this event. We used the Dubreka EVD registers and the Ebola treatment centre's (ETC) records to characterise chains of transmission. Real-time field Ebola virus sequencing was employed to support epidemiological results. An epidemiological cluster of 32 cases was found, of which 27 were laboratory confirmed, 24 were isolated and 20 died. Real time viral sequencing on 12 cases demonstrated SL3 lineage viruses with sequences differing by one to three nt inside a single phylogenetic cluster. For isolated cases, the average time between symptom onset and ETC referral was 2.8 days (interquartile range (IQR): 1-4). The average time between sample collection and molecular results' availability was 3 days (IQR: 2-5). In an area with scarce resources, the genetic characterisation supported the outbreak investigations in real time, linking cases where epidemiological investigation was limited and reassuring that the responsible strain was already circulating in Guinea. We recommend coupling thorough epidemiological and genomic investigations to control EVD clusters. PMID- 29589582 TI - Spectrum of CFTR gene sequence variants in a northern Portugal population. AB - : In Portugal, the spectrum of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene variants is not known. The main objective of this work was to determine the type and frequency of CFTR variants in a sample from northern Portugal by the complete analysis of the CFTR coding sequencing performed in 512 Portuguese children. A total of 30 different CFTR sequence variants, already reported as cystic fibrosis (CF) or CFTR related disorders variants, were detected. Ninety-two children (18.0%; 95%CI: 14.7-21.6) were found to be carriers of one sequence variant and 8 (1.6%; 95%CI: 0.7-3.1) had two sequence variants. Taking into consideration only variants that may cause CF when combined with a pathogenic CF variant, the CF pathogenic variant carrier frequency was 3.3% (95%CI: 1.9-5.3). One (0.2%; 95%CI: 0.01-0.7) child presented two CF pathogenic variants. CONCLUSIONS: The majority of CFTR variants detected have been associated with a less severe CF phenotype. A wide spectrum of CFTR variants was identified, confirming the highest CFTR allelic heterogeneity previously reported in Mediterranean country. Additionally, better knowledge about the CFTR sequence variation spectrum may contribute to more efficient genetic testing in the Portuguese population.

AB - BACKGROUND AND OBJECTIVE: Serum tryptase (ST) decreases during long-term venom immunotherapy (VIT). ST also exhibits a circadian variation, with a small decrease after sting challenge. Both findings have been related to successful VIT. Objective: To assess whether variation (increase or decrease) in ST on the first day of VIT is associated with the likelihood of future systemic adverse reactions (SARs) during treatment. METHODS: We prospectively studied patients who underwent cluster VIT, which was continued for at least 6 months. ST was measured on the first day of VIT, before the first dose (pre-IT tryptase) and after the last dose (post-IT tryptase). Differences between patient groups (with and without SAR) were analyzed. RESULTS: A total of 160 courses of VIT were administered to 150 patients. The median baseline ST value was 4.3 MUg/L. A total of 25 courses (15.6%) were associated with SAR. In 64% of the 25 patients with SAR, the post-IT tryptase value was higher than the pre-IT tryptase level; the median increment was 19% in these patients. We found a significant association between the increase in ST on the first day of VIT and future SARs (risk ratio, 7.6). This elevation was independent of the scheduled VIT day, severity of the SAR, and baseline ST value. CONCLUSIONS: A slight increase in tryptase on the first day of VIT is an independent variable that is strongly related to a high risk of future SAR. This simple biomarker could improve patient safety. PMID- 29589587 TI - Immune activation, inflammation and HIV DNA after 96-weeks of ATV/r monotherapy: a MODAt substudy.

AB - The ground-state phase diagram of a two-leg fermionic dipolar ladder with inter site interactions is studied using density matrix renormalization group (DMRG) techniques. We use a state-of-the-art implementation of the DMRG algorithm and finite size scaling to simulate large system sizes with high accuracy. We also consider two different model systems and explore stable phases in half and quarter filling factors. We find that in the half filling, the charge and spin gaps emerge in a finite value of the dipole-dipole and on-site interactions. In the quarter filling case, s-wave superconducting state, charge density wave, homogenous insulating and phase separation phases occur depend on the interaction values. Moreover, in the dipole-dipole interaction, the D-Mott phase emerges when the hopping terms along the chain and rung are the same, whereas, this phase has been only proposed for the anisotropic Hubbard model. In the half filling case, on the other hand, there is either charge-density wave or charged Mott order phase depends on the orientation of the dipole moments of the particles with respect to the ladder geometry. PMID- 29589589 TI - Chromosome aberrations in workers occupationally exposed to tritium. AB - This paper reports the findings of an historical chromosome analysis for unstable aberrations, undertaken on 34 nuclear workers with monitored exposure to tritium. The mean recorded beta-particle dose from tritium was 9.33 mGy (range 0.25-79.71 mGy) and the mean occupational dose from external, mainly gamma-ray, irradiation was 1.94 mGy (range 0.00-7.71 mGy). The dicentric frequency of 1.91 +/- 0.53 * 10 3 per cell was significantly raised, in comparison with that of 0.61 +/- 0.30 * 10-3 per cell for a group of 66 comparable worker controls unexposed to occupational radiation. The frequency of total aberrations was also significantly higher in the tritium workers. Comparisons with in vitro studies indicate that at these dose levels an increase in aberration frequency is not expected. However, the available historical tritium dose records were produced for the purposes of radiological protection and based on a methodology that has since been updated, so tritium doses are subject to considerable uncertainty. It is therefore recommended that, if possible, tritium doses are reassessed using information on historical recording practices in combination with current dosimetry methodology, and that further chromosome studies are undertaken using modern FISH techniques to establish stable aberration frequencies, as these will provide information on a cumulative biological effect.

AB - The mixed spin-(1,1/2) Ising-Heisenberg double sawtooth ladder containing a mixture of both spin-1 and spin-1/2 nodal atoms, and the spin-1/2 interstitial dimers are approximately solved by the transfer-matrix method. Here, we study in detail the ground-state phase diagrams, also influences of the bilinear exchange coupling on the rungs and cyclic four-spin exchange interaction in square plaquette of each block on the magnetization and magnetic susceptibility of the suggested ladder at low temperature. Such a double sawtooth ladder may be found in a Shastry-Sutherland lattice-type. In spite of the spin ordering of odd and even blocks being different from each other, due to the commutation relation between all different block Hamiltonians, phase diagrams, magnetization behavior and thermodynamic properties of the model are the same for odd and even blocks. We show that at low temperature, both exchange couplings can change the quality and quantity of the magnetization plateaus versus the magnetic field changes. Specially, we find a new magnetization plateau [Formula: see text] for this model. Besides, we examine the magnetic susceptibility and specific heat of the model in detail. It is proven that behaviors of the magnetization and the magnetic susceptibility coincide at low temperature. The specific heat displays diverse temperature dependencies, which include a Schottky-type peak at a special temperature interval. We observe that with increase of the bilinear exchange coupling on the rungs, second peak temperature dependence grows.

AB - OBJECTIVE: We demonstrate here the first successful implementation in humans of a proof-of-concept system for restoring and improving memory function via facilitation of memory encoding using the patient's own hippocampal spatiotemporal neural codes for memory. Memory in humans is subject to disruption by drugs, disease and brain injury, yet previous attempts to restore or rescue memory function in humans typically involved only nonspecific, modulation of brain areas and neural systems related to memory retrieval. APPROACH: We have constructed a model of processes by which the hippocampus encodes memory items via spatiotemporal firing of neural ensembles that underlie the successful encoding of short-term memory. A nonlinear multi-input, multi-output (MIMO) model of hippocampal CA3 and CA1 neural firing is computed that predicts activation patterns of CA1 neurons during the encoding (sample) phase of a delayed match-to sample (DMS) human short-term memory task. MAIN RESULTS: MIMO model-derived electrical stimulation delivered to the same CA1 locations during the sample phase of DMS trials facilitated short-term/working memory by 37% during the task. Longer term memory retention was also tested in the same human subjects with a delayed recognition (DR) task that utilized images from the DMS task, along with images that were not from the task. Across the subjects, the stimulated trials exhibited significant improvement (35%) in both short-term and long-term retention of visual information. SIGNIFICANCE: These results demonstrate the facilitation of memory encoding which is an important feature for the construction of an implantable neural prosthetic to improve human memory. PMID- 29589593 TI - Fermi-edge singularity and the functional renormalization group. AB - We study the Fermi-edge singularity, describing the response of a degenerate electron system to optical excitation, in the framework of the functional renormalization group (fRG). Results for the (interband) particle-hole susceptibility from various implementations of fRG (one- and two-particle irreducible, multi-channel Hubbard-Stratonovich, flowing susceptibility) are compared to the summation of all leading logarithmic (log) diagrams, achieved by a (first-order) solution of the parquet equations. For the (zero-dimensional) special case of the x-ray-edge singularity, we show that the leading log formula can be analytically reproduced in a consistent way from a truncated, one-loop fRG flow. However, reviewing the underlying diagrammatic structure, we show that this derivation relies on fortuitous partial cancellations special to the form of and accuracy applied to the x-ray-edge singularity and does not generalize.

AB - BACKGROUND The aims of this study were to investigate the effects of mercaptoethanol treatment on the expression of mediators of oxidative stress, inflammation, and extracellular matrix (ECM) degeneration in a mouse aortic dissection (AD) model. MATERIAL AND METHODS Twenty-four 8-month-old C57BL/6J mice were divided into three groups and studied for two weeks: 1) the aortic dissection (AD) Model group (N=8) underwent intraperitoneal injection of angiotensin II (Ang II) (5 ml/kg) three times every 24 h; 2) the mercaptoethanol Treated group (N=8) were given oral mercaptoethanol (2.5 mM); the Normal group (N=8) underwent intraperitoneal injection of noradrenaline (5 mg/kg) three times every 24 h. Sections of mouse aorta were prepared for histology with hematoxylin and eosin (H&E) staining; immunohistochemistry was performed to detect levels of: nuclear factor (erythroid-derived 2)-like 2 (NFE2L2), nuclear factor kappaB (NF kappaB), p65, superoxide dismutase-1 (SOD1), glutamate cysteine ligase catalytic subunit (GCLC), tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL 1beta), and matrix metalloproteinase-9 (MMP9). Quantitative reverse transcription polymerase chain reaction (RT-PCR) evaluated mRNA expression of SOD1, GCLC, TNF alpha, IL-1beta, and MMP9. RESULTS Mercaptoethanol treatment inhibited Ang II induced aortic dissection in AD mice, as shown histologically. Mercaptoethanol treatment reduced the expression levels of NFE2L2, NF-kappaB, p65, TNF-alpha, IL 1beta and increased the expression levels of SOD1, MMP9, and GCLC. CONCLUSIONS In an AD mouse model, mercaptoethanol treatment inhibited thoracic and abdominal aortic dissection and reduced aortic tissue expression of mediators of oxidative stress and inflammation and increased the activation of ECM signaling pathways.

Coenzyme Q10 (CoQ10) has great therapeutic potential for DN. However, the clinical application of CoQ10 has been limited because of its low water solubility and non-specific distribution. Liposomes were supposed to be an effective way for delivering CoQ10 to kidney. CoQ10 was effectively encapsulated into the liposome (CoQ10-LIP) with a high entrapment efficiency of 86.15 %. The CoQ10-LIP exhibited a small hydrodynamic diameter (180 +/- 2.1 nm) and negative zeta potential (-18.20 mV). Moreover, CoQ10-LIP was combined with ultrasound mediated microbubble destruction (UTMD) to enhance specific distribution of CoQ10 in kidney. In early stage of diabetic mellitus (DM), rats were administrated with CoQ10-LIP followed by UTMD (CoQ10-LIP+UTMD) to prevent occurrence of DN. Results revealed that CoQ10-LIP+UTMD effectively prevented the renal morphology and function of diabetics rats from damage. The protective mechanism of CoQ10-LIP was highly associated with protecting podocyte, promoting vascular repair and inhibiting cell apoptosis. Conclusively, CoQ10-LIP in combination with UTMD might be a potential strategy to prevent occurrence of DN.

PMID- 29589599 TI - Continuous Monitoring of Respiratory Rate on General Wards What might the implications be for Clinical Practice? AB - A high respiratory rate is a significant predictor of deterioration. The accuracy of measurements has been questioned. We performed a prospective observational study of automated electronic respiratory rate measurements and compared measurements with electronic counts obtained in the 10 minutes prior to the manual measurement. For 182 patients 1331 matching measurements could be compared. The mean age of these patients was 68 (SD 14) years. 96 (53%) of patients were female. While mean and median measurements were similar frequency distributions were significantly different. Manual measurements were markedly lower than electronic measurements in patients with higher respiratory rates. While electronic measurements are likely to be more reliable clinical implications require further investigation to clarify whether existing algorithms including Early Warning Scores will need adjustment. PMID- 29589600 TI - Can an acute admission to hospital be an opportunity for healthcare professionals to provide physical activity advice? A qualitative study of patients' perspectives. AB - Physical inactivity causes morbidity, mortality and healthcare expenditure. A minority of people undertake sufficient physical activity to meet the DoH recommendations. NICE has determined that brief advice in primary care is costeffective in increasing physical activity levels but there is no current recommendation for secondary care. Acute medical admissions represent "teachable moments" where patients might be receptive to advice. Qualitative methodology was used to determine the perspectives of acute medical in-patients on their willingness to receive physical activity advice and on its format and delivery. Most participants thought physical activity should be discussed by health care professionals if it related to the reason they were admitted to hospital but wanted individually-tailored advice on overcoming their specific barriers to physical activity. PMID- 29589601 TI - Relationship of the clinical acuity & complexity to the outcome of an emergency medical admission. AB - BACKGROUND: An Illness Severity and Co-morbidity composite score can predict 30 day mortality outcome. METHODS: We computed a summary risk score (RS) for emergency medical admissions and used cluster analysis to define four subsets Results: Four cluster groups were defined. Cluster 1 - RS 7 points (IQR 5, 8) Cluster 2 - 9 (IQR 8, 11), Cluster 3 - 12 (IQR 11, 13) and Cluster 4 - 14 (IQR 13, 15). Clusters predicted 30-day in hospital mortality OR 1.86 (95%CI: 1.82, 1.92); respective rates 1.4% (95% CI: 1.3%, 1.6%), 3.4% (95% CI: 3.1%, 3.6%), 7.8% (95% CI: 7.5%, 8.1%) and 16.5% (95% CI: 15.7%, 17.2%). CONCLUSION: Cluster grouping of Risk Score was age related; strongest outcome determinant was Acute Illness Severity. PMID- 29589602 TI - The predictive value of leucocyte progression for one-week mortality on acutely admitted medical patients to the emergency department. AB - OBJECTIVE: To clarify if leucocyte count progression can predict one-week mortality in unselected medical patients admitted to the emergency department. Additionally, we investigated the importance of leucocyte count progression for admission to the intensive care unit and length of stay. METHOD: This retrospective cohort study uses data collected in two phases from patients admitted through the emergency department at Hospital of South West Jutland. Upon admission, a nurse recorded the primary complaint and vital signs and registered these along with demographic information. Blood test results were subsequently extracted from the hospital's computer systems. Patients were separated into three groups according to the development in their leucocyte count from the day of admission to the day after. RESULTS: The total cohort was 5894 patients; 30.5% remained after exclusion. Median age was 71, and 50.3% were female. Using logistic regression, we found significantly lower one-week mortality with falling leucocyte count progression, even when controlling for confounders. A decreasing leucocyte count had a sensitivity for one-week mortality of 65%, specificity of 62%, positive predictive value of 4%, and negative predictive value of 99%. Difference in admission to the intensive care unit was non-significant between the three groups. Difference in length of stay was significant, but with one day difference, the clinical significance is questionable. CONCLUSION: Leucocyte count progression is not sensitive enough to predict one-week mortality, nor specific enough to discount it. It is important for physicians to be aware of this to avoid faulty assessments based on imprecise assumptions. PMID- 29589603 TI - Acute kidney injury in kidney transplant patients. AB - Managing kidney transplant patients in an acute medical unit can be challenging, as patients have a single functioning kidney, underlying chronic kidney disease, and are immunosuppressed. Transplant patients develop AKI for all usual reasons but the differential diagnosis is wider and includes specific problems, such as obstruction of a single functioning kidney, vascular thrombosis, rejection, drug toxicity and drug-induced thrombotic microangiopathy. Septic AKI is common but again, the differential diagnosis of sepsis is wider. Transplant patients are at higher risk of developing both community and opportunistic infections, especially in the first year after the transplant or after any increase in immunosuppressive medication. In addition, there is always a risk of rejection, especially in case of reduction of immunosuppressive medications. Therefore, any change in the immunosuppressive therapy should to be discussed with the transplant team to achieve an appropriate balance between avoiding rejection and preventing opportunistic infections. PMID- 29589604 TI - Nephrotic syndrome in adults. AB - Nephrotic syndrome is an important presentation of glomerular disease characterised by heavy proteinuria, hypoalbuminaemia and oedema. The differential diagnosis of the underlying condition is wide including primary renal disorders and secondary diseases such as malignancy, infection, diabetes and amyloid. Presentations to acute medicine may be with hypervolaemia, complications of the nephrotic state (such as venous thromboembolism), or complications of therapy (such as infection). Early recognition of nephrotic syndrome is possible through simple urinalysis for protein and testing serum albumin, although a high index of suspicion is sometimes required in patients with comorbidities including potentially distracting cardiac or hepatic diseases. PMID- 29589605 TI - Managing thyrotoxicosis in the acute medical setting. AB - Thyrotoxicosis is common and can present in numerous ways with patients exhibiting a myriad of symptoms and signs. It affects around 1 in 2000 people annually in Europe1. The thyroid gland produces two thyroid hormones - thyroxine (T4) and triiodothyronine (T3). Thyroxine is inactive and is converted by the tissues and organs that need it into tri-iodothyronine. In health, the production of these thyroid hormones is tightly regulated by the secretion of thyroid stimulating hormone (TSH; thyrotropin) from the pituitary gland. The term 'thyrotoxicosis' refers to the clinical manifestations of hyperthyroidism. PMID- 29589606 TI - A young breathless patient. AB - A 34-year-old gentleman, with a background of osteoarthritis, presented to the Acute Medical Unit with a short history of breathlessness. He had returned from holiday to the United States five days previously. Since return, he had complained of myalgia, sore throat, a non-productive cough, mild anorexia and fevers at home. More acutely, prompting his presentation to hospital, was acute dyspnoea, which was sudden onset, with some central anterior chest discomfort and worse lying flat. PMID- 29589607 TI - A Catastrophic Consequence of Cramp. AB - Quinine has long been used for the treatment of conditions such as malaria and leg cramps, and is also present at low levels in some beverages; however, it can cause serious side effects. We describe a patient who developed severe haemolysis, thrombocytopaenia, and acute kidney injury following the ingestion of a single dose of quinine. This case demonstrates the importance of awareness of such potentially life-threatening consequences of exposure to this agent. PMID- 29589608 TI - Insight into selectivity: uptake studies of radionuclides 90Sr2+, 137Cs+, and 233UO22+ with bis-amidoxime polymers. AB - Uptake characteristics of a bis-amidoximated polymer are presented for 90Sr2+, 137Cs+, and 233UO22+ to assess rational ligand design and polymer engineering efforts applied to selective uranium extraction. Functionalized with the bis amidoxime diaryl ether ligand at a loading of 1.98 mmol per gram of polymer, the polymer was found to sorb uranium from a pH 6 solution with a separation factor (alpha) over cesium of 1.2 * 103. Strontium uptake was negligible throughout the pH range studied whereas cesium uptake averaged <30%. Moreover, at near neutral pH, the sorbent was able to purify water to below the United States' set maximum contaminant level for uranium, decreasing the U concentration from 330 ppb to below 3 ppb in 30 minutes. Density functional theory (DFT) calculations, used to probe the nature of the metal-bis-amidoxime interaction, help inform the empirically realized uptake selectivity. PMID- 29589610 TI - Solvent-free synthesis of monodisperse Cu nanoparticles by thermal decomposition of an oleylamine-coordinated Cu oxalate complex. AB - Cu nanoparticles (NPs) are widely used in numerous applications because of their unique optical, catalytic, and electrical properties. However, the synthesis of monodisperse Cu NPs often involves harmful reducing agents under an inert atmosphere in a solution with low Cu ion concentrations. In this study, monodisperse Cu NPs were synthesized by the thermal decomposition of an oleylamine-coordinated Cu oxalate (Cu(ox)) complex (OA-Cu(ox)) in oleylamine in air with no reducing agent. The structure of OA-Cu(ox) was analyzed using Fourier transform infrared spectroscopy. The decomposition temperature of the oxalate ion was reduced to 130 degrees C from that of Cu(ox) (300 degrees C) because of the coordination of the primary amino group of oleylamine with the Cu ion of Cu(ox). Furthermore, the decomposition temperature of OA-Cu(ox) strongly affected the size distribution of the synthesized Cu NPs. Monodisperse Cu NPs were successfully synthesized by the thermal decomposition of OA-Cu(ox) at temperatures higher than 240 degrees C with high yield (~90%). The synthesized Cu NPs were readily dispersed in toluene. PMID- 29589609 TI - Upregulating mTOR/ERK signaling with leonurine for promoting angiogenesis and tissue regeneration in a full-thickness cutaneous wound model. AB - Wound therapy remains a clinical challenge due to the poor vascularization during the healing process and the high demand to achieve functional and aesthetically satisfactory scars. Newly-formed blood vessels are necessary for wound healing since they can deliver nutrients and oxygen to the wound area. In this study, the role of leonurine (LN), a traditional Chinese medicine isolated from Herba leonuri, in promoting angiogenesis and its function in wound healing have been investigated. The results of co-culture with human umbilical vein endothelial cells (HUVECs) demonstrated that LN treatment (5-20 MUM) could promote the proliferation and migration and enhance the ability of in vitro angiogenesis through up-regulating the mTOR/ERK signaling pathway. Furthermore, a full thickness cutaneous wound model was used to investigate the healing effect of LN in vivo. Intragastric administration of 20 mg per kg per day LN stimulated the regeneration of more blood vessels at the wound sites, which confirmed the in vitro results of promoting angiogenesis. Due to fast vascularization, the collagen matrix deposition and remodeling processes were also accelerated in LN treated wounds, resulting in efficient wound healing. In summary, LN promoted angiogenesis of endothelial cells in vitro by activating the mTOR/ERK pathway, and could efficiently enhance the angiogenesis and collagen deposition of the regenerated tissue, together with facilitating the wound healing process in vivo. This study provides evidence for LN-stimulated angiogenesis and tissue regeneration in skin wounds, especially in ischemic wounds. PMID- 29589611 TI - Experimental evidence of TICT state in 4-piperidinyl-1,8-naphthalimide - a kinetic and mechanistic study. AB - The excited state processes in N-propyl-4-piperidinyl-1,8-naphthalimide have been studied by measuring its fluorescence spectra and decay curves in solvents of different polarity and viscosity and also in a frozen solvent glass. The results unanimously proved the formation of a dark twisted intramolecular charge transfer (TICT) state from the emissive charge transfer (CT) species, the direct product of excitation. The rate coefficients of the TICT process and the deactivations of the CT and TICT species were determined, using a reversible two-state kinetic model. The temperature dependence of the kinetic data was consistent with a kinetic barrier consisting of three terms, the inherent barrier of the reaction, and the contributions of the solute-solvent interactions related to the solvent viscosity and polarity. The potential energy surfaces were calculated in the S0 and the S1 states along the coordinate of turning motion which was conclusive concerning the direction of the twisting and indicated a possible conformational change of the piperidinyl unit. The theoretical calculations confirmed that the TICT species is dark and has a stronger charge transfer character compared to the CT state. PMID- 29589612 TI - One-step synthesis of MnS/MoS2/C through the calcination and sulfurization of a bi-metal-organic framework for a high-performance supercapacitor and its photocurrent investigation. AB - Based on a Mn/Mo-metal organic framework (MOF) precursor, [Mn(4,4'-bipyridine)0.5 MoO4].1.5H2O, a MnS/MoS2/C hybrid was synthesized through a calcination and sulfurization approach and it is mainly constituted by MoS2/C nanorods and MnS/MoS2/C nanoflakes. The MnS/MoS2/C hybrid delivers a high specific capacitance of 1162 F g-1 at 0.5 A g-1 in 2 M KOH electrolyte, and it possesses a good rate capacity with a retention of 75.7% (880 F g-1) at 10 A g-1, which is due to the synergetic effects of the components MnS, MoS2 and carbon matrix in the hybrid material. The carbon matrix in the hybrid material can not only anchor the active components of MnS and MoS2, but also transport electrons efficiently. The completely exposed Mo and S edges on the preferential 2H-(002) and 3R-(003) facets of MoS2 are beneficial for ion adsorption and electrochemical reaction. An asymmetric supercapacitor constructed by the MnS/MoS2/C hybrid (positive electrode) and activated carbon (AC) (negative electrode) exhibited a capacitance retention of 81% after 5000 galvanostatic charge-discharge cycles (GCD). During the GCD process, the metal sulfides were probably transformed into metal hydroxides in the presence of OH- electrolyte ions. In addition, the MnS/MoS2/C hybrid exhibits a visible light-driven photocurrent response, and DFT calculation proves that it is attributed to the semiconducting feature of MoS2 in the hybrid. PMID- 29589613 TI - All-inorganic CsPbBr3 perovskite quantum dots embedded in dual-mesoporous silica with moisture resistance for two-photon-pumped plasmonic nanoLasers. AB - Lead halide perovskite nanocrystals with efficient two-photon absorption and ease of achieving population inversion have been recognized as good candidates to achieve frequency up-conversion for biophotonics applications, but suffer from the limitation of the miniaturization of the device and its corresponding poor stability when exposed to atmospheric moisture. Here we demonstrate the miniaturization of plasmonic nanolasers via embedding perovskite quantum dots (QDs) in rationally designed dual-mesoporous silica with gold nanocore. The nanocomposite supports resonant surface plasmon-polaritons (SPPs), which overlap both spatially and spectrally with the CsPbBr3 QDs. The outcoupling between surface plasmon oscillations and photonics modes within a wavelength range completely overcomes the loss of localized surface plasmons, and finally contributes to a novel application of two-photon-pumped nanolasers. Large optical gain under two-photon excitation was observed as a result of resonant energy transfer from excited perovskite QDs to surface plasmon oscillations and stimulated emission of surface plasmons in a luminous mode. The outmost organic inorganic hybrid shells of the dual-mesoporous silica nanocomposites act as a protective layer of the perovskite QDs against water and endow the nanocomposites with superhydrophobicity. This work provides an alternative inspiration for the design of new two-photon pumped nanolasers. PMID- 29589614 TI - An in situ spectroelectrochemical study on the orientation changes of an [FeiiiLN2O3] metallosurfactant deposited as LB Films on gold electrode surfaces. AB - In this paper we analyze the changes in molecular orientation triggered by electrochemical reduction of an iron-containing surfactant in Langmuir-Blodgett films deposited onto gold electrodes. The metallosurfactant [Feiii(LN2O3)] (1) is an established molecular rectifier capable of unidirectional electron transfer between two electrodes. A gradual decrease in the activity is observed in sequential current vs. potential curves upon repeated cycles. Here we evaluate the redox response associated with the reduction of the Feiii/Feii couple in a single monolayer, as well as in a 5-layer LB film of 1. We use polarization modulation infrared reflection absorption spectroscopy (PM IRRAS) to follow structural and orientation changes associated with such applied potential scans. We observe that the reduction of the Fe center becomes increasingly irreversible because an Fe-Ophenolate bond is cleaved. This transformation is accompanied by an almost vertical change in the orientation of metallosurfactant molecules in LB films.

AB - Here, we demonstrate that a type-II g-C3N4 nanosheet (CNNS)/W18O49 heterostructure composite can be switched to Z-scheme through the deposition of Au nanoparticles (NPs) on the surface of CNNS. As a direct result, the designed Au/CNNS/W18O49 heterostructure shows enhanced photocatalytic performance for Cr(vi) reduction than the CNNS/W18O49 heterostructure and single components (CNNS and W18O49) under visible light irradiation.

PMID- 29589617 TI - Exploring the methanol decomposition mechanism on the Pt3Ni(100) surface: a periodic density functional theory study. AB - The detailed mechanism of the methanol decomposition reaction (MDR) on the Pt3Ni(100) surface is studied based on self-consistent periodic density functional theory calculations. The geometries and energies of methanol and its intermediates involved in MDR are analyzed, and the reaction network is constructed to illustrate the MDR mechanisms. The possible pathways through initial scission of the O-H, C-H, and C-O bonds in methanol are discussed based on the steric effect and electronic structure of the related transition states and the Bronsted-Evans-Polanyi (BEP) relationships. The initial scission of the O H bond is favorable and bears the lowest energy barrier among the three decomposition modes (initial scission of O-H, C-H, and C-O bonds). Potential energy surface (PES) analysis confirmed that although the initial scission of the O-H bond is more favorable than scission of the C-H bond, the initial scission of the C-H bond can actually occur because of the very low energy barrier for further dehydrogenation of CH2OH via scission of its O-H bond. Thus, the pathway for MDR on the Pt3Ni(100) surface may possibly proceed via two competitive pathways: CH3OH -> CH3O -> CH2O -> CHO -> CO and CH3OH -> CH2OH -> CH2O -> CHO -> CO. Comparisons between the current results and the MDR on other systems are made and show that Pt3Ni(100) can be a good catalyst for MDR. PMID- 29589618 TI - Safety considerations of plant polysaccharides for food use: a case study on phenolic-rich softwood galactoglucomannan extract. AB - A growing population and concern over the sufficiency of natural resources for feeding this population have motivated researchers and industries to search for alternative and complementary sources of food ingredients and additives. Numerous plant species and parts of plants are explored as raw materials for food production. An interesting example is wood; to date, only a few wood-based additives or ingredients are authorized for food use. Wood hemicelluloses, such as softwood galactoglucomannans (GGM), constitute an abundant bioresource that shows a high potential functionality in edible materials. Spruce GGM acts as a multi-functional emulsion stabilizer, and it could be used in various processed food products, replacing less effective, conventional emulsifiers. Before new materials can be released into the food market, their safety must be evaluated, according to the Novel Food regulation. This review focuses on the safety aspects that must be considered before polysaccharide- and phenolic-rich plant extracts can be awarded the status of authorized food ingredients. In this review, GGM is presented as a case study and examples are given of plant-based polysaccharides that are already authorized for food purposes. The legislation regarding Novel Food ingredients in Europe is also briefly reviewed. PMID- 29589619 TI - One-pot synthesis of N-doped carbon dots by pyrolyzing the gel composed of ethanolamine and 1-carboxyethyl-3-methylimidazolium chloride and their selective fluorescence sensing for Cr(vi) ions. AB - N-Doped carbon dots (CDs) were directly synthesized with a high yield of 21.85% by one-pot pyrolysis of a gel composed of ethanolamine and 1-carboxyethyl-3 methylimidazolium chloride at 220 degrees C for 2 h. The as-synthesized CDs with a mean particle size of 7.8 nm were uniform, amorphous, and abundant in nitrogen content (23.15 wt%) and surface groups such as amide and hydroxyl. Thus, the CDs exhibited good water-solubility, bright blue excitation- and pH-dependent fluorescence with a quantum yield of 17.93%, and high ionic strength tolerance. In addition, a CD-based fluorescent sensor towards Cr(vi) ions with favorable sensitivity and selectivity was constructed based on the inner filter effect. Two good linear relationships between the concentration of Cr(vi) ions and the PL quenching efficiency were obtained in the ranges from 0.2 to 2 (R2 = 0.9965) and 2-40 MUM (R2 = 0.9918), and the limits of detection (LOD = 3sigma/S) were calculated as 0.018 and 0.25 MUM, respectively. Importantly, this sensor was solid and capable of rapidly detecting Cr(vi) ions in tap water with detection ranges of 0.2-2 (R2 = 0.9817) and 2-60 MUM (R2 = 0.9902), LODs of 0.048 and 0.40 MUM, and recoveries of 102.1-106%.

AB - Direct structural evidence for group 11 metal-mediated B-B bond activation was obtained from reactions of tri(tert-butyl)azadiboriridine (1) with AuCl(L) complexes. The AuCl(SMe2) reaction afforded [eta2-B,B-B(tBu)N(tBu)B(tBu)]AuCl (2) by ligand displacement. More donating phosphines as co-ligands led to B-B bond cleavage accompanied by either halide or L migration to form boron-gold complexes 3 (L = PPh3) and 4 (L = PMe3). A similar product 5, which is isostructural to 4, was obtained by the addition of dimethylaminopyridine (DMAP) to 2-4. Complexes 2 5 constitute rare examples of metal complexes bearing two Lewis acidic centres. The effect of the boryl ligand was demonstrated in the formation of a gold(i) complex 6 bearing a 5-membered heterocycle from 3 and tert-butylisonitrile. Plausible reaction mechanisms that led to these complexes and their bonding situation were explored computationally at the DFT level.

PMID- 29589622 TI - Orientation direction dependency of cavitation in pre-oriented isotactic polypropylene at large strains. AB - Orientation direction dependency of whitening activated at large strains was studied using four pre-oriented isotactic polypropylene (iPP) samples with different molecular weights stretched along different directions with respect to the pre-orientation (0 degrees , 45 degrees , and 90 degrees ) by means of in situ wide-, small-, and ultra-small-angle X-ray scattering techniques. A macroscopic fracture of iPP materials was also observed following the stress whitening at large strains. These two associated processes in pre-oriented iPP samples at elevated temperatures were found to be governed by not only the molecular weight of iPP but also the pre-orientation direction. For a certain pre orientation direction of iPP, both the critical stress of cavitation induced whitening and failure stress increased with increasing molecular weight. For one given molecular weight, the pre-oriented iPP showed the smallest critical stress for whitening and failure stress along the pre-orientation direction (0 degrees ) while the samples displayed larger values for the same behaviors when stretched at 45 degrees or 90 degrees with respect to the pre-orientation direction. Such behavior suggested that oriented amorphous networks, with different mechanical strengths, can be generated during the second deformation processes in these pre oriented iPP samples. The evolution of inter-fibrillar tie chains in highly oriented amorphous networks was considered as the main factor controlling the response of the inner network to the external stress since the cavitation-induced whitening activated at large strains was caused by the failure of load bearing inter-fibrillar tie chains in the oriented amorphous network. PMID- 29589623 TI - Nanoparticle-cell interactions induced apoptosis: a case study with nanoconjugated epidermal growth factor. AB - In addition to the intrinsic toxicity associated with the chemical composition of nanoparticles (NP) and their ligands, biofunctionalized NP can perturb specific cellular processes through NP-cell interactions and induce programmed cell death (apoptosis). In the case of the epidermal growth factor (EGF), nanoconjugation has been shown to enhance the apoptotic efficacy of the ligand, but the critical aspects of the underlying mechanism and its dependence on the NP morphology remain unclear. In this manuscript we characterize the apoptotic efficacy of nanoconjugated EGF as a function of NP size (with sphere diameters in the range 20-80 nm), aspect ratio (A.R., in the range of 4.5 to 8.6), and EGF surface loading in EGFR overexpressing MDA-MB-468 cells. We demonstrate a significant size and morphology dependence in this relatively narrow parameter space with spherical NP with a diameter of approx. 80 nm being much more efficient in inducing apoptosis than smaller spherical NP or rod-shaped NP with comparable EGF loading. The nanoconjugated EGF is found to trigger an EGFR-dependent increase in cytoplasmic reactive oxygen species (ROS) levels but no indications of increased mitochondrial ROS levels or mitochondrial membrane damage are detected at early time points of the apoptosis induction. The increase in cytoplasmic ROS is accompanied by a perturbation of the intracellular glutathione homeostasis, which represents an important check-point for NP-EGF mediated apoptosis. Abrogation of the oxidative stress through the inhibition of EGFR signaling by the EGFR inhibitor AG1478 or addition of antioxidants N-acetyl cysteine (NAC) or tempol, but not trolox, successfully suppressed the apoptotic effect of nanoconjugated EGF. A model to account for the observed morphology dependence of EGF nanoconjugation enhanced apoptosis and the underlying NP-cell interactions is discussed.

AB - Three isostructural metal-organic frameworks denoted as Zn(L)(aip).(H2O) (1), Zn(L)(ip).(DMF)(H2O)1.5 (2), and Zn(L)(HBTC).(H2O)2 (3) with functional groups NH2, -H and -COOH, respectively, decorated on the 1D channels have been rationally designed with the purpose of exploring the influence of electron transfer from organic ligands in the 1D channels on the sensing of nitro explosives and antibiotics. These three compounds exhibit strong fluorescence in water, and they can be applied to detect the presence of explosives or antibiotics by means of fluorescence quenching in aqueous solution, whereas in terms of special explosives or antibiotics at the same concentration, 3 demonstrates a more superior quenching efficiency than 1 and 2. More importantly, it has been found that the difference in the sensing performances of these compounds is closely related to the interaction between the functional groups and guest molecules via electron and energy transfer from MOFs to explosives and antibiotics. PMID- 29589626 TI - Interplay between a crystal's shape and spatiotemporal dynamics in a spin transition material. AB - We investigated by means of optical microscopy (OM) the spatiotemporal features of the thermo-induced spin transition of [Fe(2-pytrz)2{Pd(CN)4}].3H2O (1) (2 pytrz = 4-(2-pyridyl)-1,2,4,4H-triazole) single crystals having two different shapes (triangle and rectangle). While magnetic and calorimetric measurements, performed on a polycrystalline material, showed the respective average heating and cooling transition temperatures of (Tdown1/2 ~ 152 K, Tup1/2 ~ 154 K) and (Tdown1/2 ~ 160.0 K, Tup1/2 ~ 163.5 K), OM studies performed on a unique single crystal revealed significantly different switching temperatures (Tdown1/2 ~ 152 K and Tup1/2 ~ 162 K). OM investigations showed an interface spreading over all crystals during the spin transition. Thanks to the color contrast between the low spin (LS) and the high-spin (HS) states, we have been able to follow the real time dynamics of the spin transition between these two spin states, as well as access the thermal hysteresis loop of each single crystal. After image processing, the HS-LS interface's velocity was carefully estimated in the ranges [4.4-8.5] MUm s-1 and [2.5-5.5] MUm s-1 on cooling and heating, respectively. In addition, we found that the velocity of the interface is shape-dependent, and accelerates nearby the crystal's borders. Interestingly, we observed that during the propagation process, the interface optimizes its shape so as to minimize the excess of elastic energy arising from the lattice parameter misfit between the LS and HS phases. All of these original experimental results are well reproduced using a spatiotemporal model based on the description of the spin-crossover problem as a reaction diffusion phenomenon.

AB - Browning in adipose tissues, which can be affected by diet, may mitigate the detrimental effects of adiposity and improve longer-term metabolic health. Here, browning-inducing effects of long-chain polyunsaturated fatty acids, e.g., arachidonic acid (ARA)/docosahexaenoic acid (DHA) and extensively hydrolyzed casein (eHC) were investigated in uncoupling protein 1 (Ucp-1) reporter mice. To address the overall functionality, their potential role in supporting a healthy metabolic profile under obesogenic dietary challenges later in life was evaluated. At weaning Ucp1+/LUC reporter mice were fed a control low fat diet (LFD) with or without ARA + DHA, eHC or eHC + ARA + DHA for 8 weeks until week 12 after which interventions continued for another 12 weeks under a high-fat diet (HFD) challenge. Serology (metabolic responses and inflammation) and in vivo and ex vivo luciferase activity were determined; in the meantime browning-related proteins UCP-1 and the genes peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1alpha), PR domain containing 16 (PRDM16) and Ucp-1 were examined. ARA + DHA, eHC or their combination reduced body weight gain and adipose tissue weight compared to the HFD mice. The interventions induced Ucp-1 expression in adipose tissues prior to and during the HFD exposure. Ucp-1 induction was accompanied by higher PGC1a and PRDM16 expression. Glucose tolerance and insulin sensitivity were improved coinciding with lower serum cholesterol, triglycerides, free fatty acids, insulin, leptin, resistin, fibroblast growth factor 21, alanine aminotransferase, aspartate aminotransferase and higher adiponectin than the HFD group. HFD-associated increased systemic (IL 1beta and TNF-alpha) and adipose tissue inflammation (F4/80, IL-1beta, TNF-alpha, IL-6) was reduced. Studies in a Ucp-1 reporter mouse model revealed that early intervention with ARA/DHA and eHC improves metabolic flexibility and attenuates obesity during HFD challenge later in life. Increased browning is suggested as, at least, part of the underlying mechanism.

AB - Increasing energy demands call for new energy storage technologies with high energy density to meet current and future needs. Metal-air batteries are especially attractive due to their superior specific energy, which is as much as 8 times that of today's best Li-ion batteries. However, the practical values achieved to date are far from the theoretical one and require further research to enhance the battery performance. The electrolyte plays an important role in the performance of the battery whose properties can be tuned by varying the chemical composition and through the use of additives. That is the case of ionic liquids which offer a wide variety of anion-cation combinations to realise maximum performance. This feature article overviews recent developments in ionic liquids as electrolytes for both magnesium-air and sodium-air batteries.

AB - The preparation of crystalline molecularly supertetrahedral Tn clusters with variable sizes and components is of vital importance for the fundamental study of their physicochemical properties. However, setting up an efficient method to stabilize large discrete Tn clusters is a challenge due to their high negative charges and polymerization nature. In this work, we report on the ionothermal synthesis of three discrete T4 cluster compounds, namely [Bmmim]5[(CH3)2NH2]4[NH4][M4In16S31(SH)4].6H2O (M = Mn (1), Zn (2), Cd (3), Bmmim = 1-buty-2,3-dimethyl-imidazolium), and four discrete T5 cluster compounds, namely [Bmmim]10[NH4]3[Cu5Ga30-xInxS52(SH)4] (x = 6.6 (5), 14.5 (6), 23.8 (7), and 30 (8)). The compound [Bmmim]10[NH4]3[Cu5Ga30S52(SH)4] (4) previously reported by us features a discrete T5 cluster. The steep UV-Vis absorption edges indicate band gaps of 2.20 eV for 1, 2.64 eV for 2, 2.69 eV for 3, 3.04 eV for 4, 2.65 eV for 5, 2.48 eV for 6, 2.32 eV for 7, and 2.30 eV for 8. The compositions of T5 clusters could be varied with the ratios of Ga : In in the starting reagents, providing an opportunity to systematically control the band gaps and fluorescence performances of T5 cluster-based compounds. This research might advance the understanding of the ionothermal preparation and functionality tuning of crystalline chalcogenides.

AB - Coptis chinensis inflorescence is traditionally used as tea and has been popular in the local market. C. chinensis inflorescence extract (CE) exhibits protective effects against carbon tetrachloride (CCl4)-induced damage, but the underlying mechanism remains unclear. The main chemicals of CE were detected, purified, and identified in this study. CE and linarin could reverse changes in cell viability, decrease alanine aminotransferase and aspartate transaminase levels, and reduce reactive oxygen species (ROS) generation induced by CCl4 in HepG2 cells. CE and linarin could also phosphorylate mitogen-activated protein kinases (MAPKs) and up regulate Kelth-like ECH-associated protein (Keap1). The pathways of MAPKs and Keap1 lead to the separation of Keap1 and nuclear factor (erythroid-derived 2) like 2 (Nrf2). Free Nrf2 transferred to the nucleus and enhanced the expression of phase II detoxification enzymes. This study provides a scientific basis for the use of C. chinensis inflorescence, which exhibits a hepatoprotective function, as a supplement in the food industry. PMID- 29589632 TI - Layered rare-earth hydroxide (LRH, R = Tb, Y) composites with fluorescein: delamination, tunable luminescence and application in chemosensoring for detecting Fe(iii) ions. AB - We demonstrate a novel example of tunable luminescence and the application of the delaminated FLN/OS-LRH composites (LRHs are layered rare-earth hydroxides, R = Tb, Y; FLN is the fluorescein named 2-(6-hydroxy-3-oxo-(3H)-xanthen-9-yl)benzoic acid; OS is the anionic surfactant 1-octane sulfonic acid sodium) in detecting Fe(iii) ions. The FLNxOS1-x species (x = 0.02, 0.05, 0.10, and 0.20) are intercalated into the LTbyY1-yH layers (y = 1, 0.9, 0.7, 0.5, 0.3, 0.1 and 0) by ion exchange reactions to yield the composites FLNxOS1-x-LTbyY1-yH. In the solid state, the LYH composites display green emission (564 nm) arising from the organic FLN, while in LTbH composites, the luminescence of the Tb3+ in the layers (545 nm) and the FLN in the interlayers is co-quenched. In the delaminated state in formamide (FM), FLNxOS1-x-LTbH composites display green to yellowish-green luminescence (540-574 nm) following the increasing FLN/OS ratio; while the FLN0.02OS0.98-LTbyY1-yH composites show green emission at ~540 nm. The fluorescence lifetimes of the composites (4.22-4.63 ns) are comparable to the free FLN-Na, and the quantum yields (31.62-78.70%) of the composites especially that (78.70%) of the FLN0.02OS0.98-LYH are much higher than that (28.40%) of free FLN-Na. The recognition ability of the FLN0.02OS0.98-LYH composite for metal cations is researched. The delaminated FLN0.02OS0.98-LYH colloidal suspension exhibits high selectivity for Fe3+ over other ions (Mg2+, Al3+, Ni2+, Co2+, Cu2+, Zn2+, Mn2+, Pb2+, and Cd2+) with fluorescence quenching, which can work as a kind of turn-off fluorescence sensor for the detection of Fe3+. The detection limit of Fe3+ is determined to be 2.58 * 10-8 M and the quenching constant (Ksv) is 1.70 * 103 M-1. This is the first work on LRH materials working as a chemosensor for recognising metal cations. It provides a new approach for the design of LRH materials to be applied in fluorescence chemosensing. PMID- 29589631 TI - Broad bean (Vicia faba L.) pods: a rich source of bioactive ingredients with antimicrobial, antioxidant, enzyme inhibitory, anti-diabetic and health-promoting properties. AB - This study was aimed at investigating the chemical composition (proximate, minerals, fatty acids and phenolic compounds) and the in vitro (antimicrobial, radical scavenging, anti-acetylcholinesterase and protein denaturing activities) and in vivo (anti-diabetic and histo-protective effects in alloxan-induced diabetic mice) biological activities of broad bean pods (BBPs), a food waste by product material. The results showed that BBPs have high dietary fiber (57.46%), carbohydrate (18.93%) and protein (13.81%) content versus low fat content (<1%) contributing to a low energy value of 139.24 kcal per 100 g. Profiling of fatty acids showed an abundance of the essential polyunsaturated alpha-linolenic and linoleic acids, exhibiting an excellent nutritional quality as revealed by their low atherogenic and thrombogenic indices and their hypocholesterolemic properties. The methanol extract which exhibited the highest total phenolic, flavonoid and tannin contents was found to be the most active extract in terms of antimicrobial and anti-radical activities. In alloxan-induced diabetic mice, the oral administration of a methanol extract (500 mg per kg bw) attenuated the elevated levels of serum alanine aminotransferase (ALA), aspartate aminotransferase (AST), and alkaline phosphatase activities, and urea, uric acid, and creatinine. It effectively normalized the status of lipid profiles, mitigated oxidative stress through the activation of antioxidant enzymes (CAT, GPx and SOD), and alleviated oxidative stress-mediated histopathological changes in the pancreas, liver, kidney and testis. Compositional analysis by HPLC-PDA-ESI-MS/MS revealed the presence of flavan-3-ols (catechin, epicatechin and their derivatives), flavones (apigenin derivatives) and flavonols (glycosides of quercetin and kaempferol), among others. These findings suggest that BBPs may be an effective functional food for the management of diabetes and its complications. PMID- 29589633 TI - Synthesis and coordination chemistry of enantiopure t-BuMeP(O)H. AB - Both enantiomers of the optically pure Secondary Phosphine Oxide (SPO) t BuMeP(O)H (1) have been obtained by deboronation of phosphinous acid-borane t BuMeP(O)H.BH3 (3) with HBF4 followed by hydrolysis of the intermediate adduct t BuMeP(O)H.BF3 (1.BF3), which has been isolated and crystallographically characterised. Complexes [MCl(COD)(kappaP-(R)-1)] (M = Ir, Rh; 4 and 7 respectively) have been detected in solution but could not be isolated while trans-[RhCl(CO)(kappaP-(S)-1)2] (9) has been successfully obtained in good yield. Gold complex [AuCl(kappaP-(S)-1)] (10) has been prepared and its crystal structure shows the presence of aurophilic interactions. Three new ruthenium complexes ([RuCl2(eta6-p-cymene)(kappaP-(R)-1)], 12), ([RuCl2(CO)3(kappaO-(S) 1)], 13) and trans-([RuCl2(CO)2(kappaP-(S)-1)2], 14) have been synthesised and fully characterised, including the crystal structure of 12. Four palladium coordination compounds have been prepared: trans-[PdCl2(kappaP-(S)-1)2] (trans 15), [Pd(MU-Cl)(kappaP-(S)-1)2]2 (16.OH and 16.BF2) and [Pd(MU-OAc)(kappaP-(S) 1)2] (17) and the crystal structure of complex 16.OH proves the pseudobidentate coordination of the two molecules of 1. Three organometallic allylpalladium complexes have been prepared namely [Pd(eta3-Ph2C2H3)Cl(kappaP-(S)-1)] (18) and [Pd(eta3-Ph2C2H3)(kappaP-(S)-1)2] (19.OH and 19.BF2). The crystal structure of 19.BF2 constitutes the first allylpalladium-SPO complex reported to date. PMID- 29589634 TI - Microporous carbons derived from organosilica-containing carbon dots with outstanding supercapacitance. AB - In this study, a series of strongly luminescent organosilica-modified carbon dots were successfully synthesized in a scalable manner via hydrothermal treatment of citric acid and glucose in the presence of a silane coupling agent. Organosilica as a stable component coupled with the surface of carbons leads to the formation of gel-like materials. The obtained carbon dots can be homogeneously dispersed in various polar solvents such as water or ethanol to produce an optical solution. Importantly, the abundance of organosilica groups on the surface makes carbon dots ideally suited for use as fantastic carbon precursors for the construction of porous carbon materials. The carbons resulting from the pyrolysis of carbon dots consist of interconnected carbon nanoparticles with surface areas of up to 725 m2 g-1 and nitrogen content of 4.84%. Such carbons show potential application as supercapacitor electrodes with high specific capacitance of 185.4 F g-1 at 0.5 A g-1 and 176.3 F g-1 at 1 A g-1 in 6 mol L-1 KOH. Considered a relatively green and simplistic process, this current synthetic protocol would be a promising avenue to access functional carbon materials with tunable porosity, heteroatom doping and specific morphology. PMID- 29589635 TI - Electrochemical properties of reduced graphene oxide derived through camphor assisted combustion of graphite oxide. AB - A facile method was demonstrated for the one-step synthesis of reduced graphene oxide (rGO) from graphite oxide (GO) using a camphor assisted combustion (CAC) process. Analysis of samples was carried out using FT-IR, XRD, TGA, Raman, BET, SEM and TEM techniques. The electrochemical properties of the rGO samples derived through the CAC process were determined using cyclic voltammetry, galvanostatic charge/discharge and impedance spectroscopy. It has been observed that the specific surface area and porosity of the rGO samples decrease with the increasing concentration of camphor during the CAC synthesis process. Thus, different mass ratios of GO and camphor such as 1 : 12, 1 : 16, and 1 : 20 in the CAC process yield rGO samples having surface areas (SBET) of 313.3, 297.5 and 177.4 m2 g-1. The pore volumes of the respective samples are 0.44, 0.45 and 0.23 cm3 g-1, respectively. The rGO derived using the 1 : 12 mass ratio of GO and camphor (rGO-12C) exhibits a high specific capacitance of 241 F g-1, which is significantly higher than that observed for chemically reduced graphene oxide (rGO-CR), which exhibits a specific capacitance value of only 153 F g-1. The capacitance retention of rGO-12C was found to be 98% even after 1000 galvanostatic charge-discharge (GCD) cycles, suggesting its potential applications in electrochemical energy storage.

AB - ABSTRACT: Objectives: The aim of this study was to assess whether the time of vitamin D supplementation after birth, season of birth and the type of feeding affected current body weight, body height and BMI among children aged 3-56 months from two cohorts. Additionally, it was analysed whether birth weight and birth length correlated with current BMI, body height and body weight in both cohorts of children. Methods: The study material included 1930 children from the two cohorts, measured in two following periods: 1993-1997 and 2004-2008. Finally 849 healthy individuals aged 3-56 months were included in the analysis. Multiple stepwise regression model was applied to find the group of the most important variables explaining current body weight, body height and BMI. Moreover generalized linear models for two way interactions were used. Results: The season of birth, time of supplementation of vitamin D, but also birth weight and length might affect current body weight. Individuals' height could be associated with birth length and the season of birth. BMI value was probably regulated by birth length and weight. Furthermore, interactions between the time of vitamin D supplementation and season of birth and also between the time of vitamin D supplementation and type of feeding resulting in variation of body weight and BMI in the first years of life were also observed. Conclusions: The study underlines the importance of a supplementation of vitamin D, season of birth and birth weight and length in current weight, height and body proportion in the first 3.5 years of life. PMID- 29589637 TI - Trends in the epidemiology of erysipelas in Slovenia. AB - INTRODUCTION: Erysipelas is a common infection of the skin and subcutaneous tissue. Despite the relative frequency of erysipelas, data on its basic epidemiological characteristics are scant. This study describes the trends in erysipelas epidemiology in Slovenia. METHODS: Data on notified erysipelas cases from 2000 to 2016 were extracted from the electronic database of reportable communicable diseases and analyzed. RESULTS: There were 36,254 notified cases during the observed time period of 17 years. The yearly age-standardized incidence rate of erysipelas increased from 71.5 per 100,000 in 2000 to 111.3 per 100,000 in 2016, with the main rise in the >= 75 age group. Erysipelas was more common in women, but the sex-related difference lessened in the period observed. The hospitalization rate declined. Erysipelas was significantly more frequent in the warmer period of the year. The correlation between erysipelas incidence and average monthly temperature was stronger in the <= 64 age group than in the >= 65 age group. CONCLUSIONS: Retrospective observational data confirmed a rising trend in erysipelas cases, especially among the elderly. Aging of the population will continue to increase the burden of the disease, unless health promotion and prevention lowers the prevalence of the risk factors. PMID- 29589638 TI - Psoriasis and comorbidities: general practitioners' awareness. AB - INTRODUCTION: Systemic inflammatory diseases such as psoriasis, systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA) are associated with an increased prevalence of cardiovascular diseases (CVD) and other comorbidities. The primary aim of this study was to assess the screening practices of general practitioners (GPs) with regard to the most frequent comorbidities in patients with psoriasis. METHODS: We adapted, with permission, a questionnaire that was used by Parsi et al. in 2012, which was then distributed to GP residents and consultants. RESULTS: Overall, 372 questionnaires were collected. Significantly more physicians screen for CV risk factors in patients with RA and SLE than in patients with psoriasis. There was no statistically significant difference between GP residents in the initial and final phase of residency, or between GP residents and consultants regarding awareness of increased prevalence of CVD in psoriasis or comorbidity screening practices in psoriasis patients. CONCLUSIONS: Most GP residents and consultants that participated in this study are not aware of an increased CV risk in patients with psoriasis and assign greater importance regarding this risk to other inflammatory diseases such as RA and SLE. PMID- 29589639 TI - Oral manifestations of autoinflammatory and autoimmune diseases. AB - Autoimmune diseases may also be reflected in changes in the oral cavity that represent the first sign of the disease, or they may occur simultaneously with or later in the course of the disease. Oral findings are mostly non-specific, and therefore further investigations are needed to exclude or confirm possible diagnoses. This article presents the most important diseases in this research area, divides them into meaningful groups, and highlights the importance of examining the oral cavity for possible manifestations. PMID- 29589640 TI - The role of regulatory T cells and anti-inflammatory cytokines in psoriasis. AB - Psoriasis is a chronic inflammatory disease with a genetic predisposition that can be triggered by environmental factors. Pathogenesis is characterized by activation of the Th1/Th2 axis and abnormalities of the Th17/Treg balance as well as deficiency of anti-inflammatory cytokines (IL-10, TGF-beta). Regulatory lymphocytes (Treg), which are involved in homeostasis mechanisms, maintain tolerance and prevent autoimmune disorders. Only a few studies have investigated the presence of Treg marker expression and levels of anti-inflammatory cytokines in psoriatic skin and sera of patients with psoriasis. The results of studies are controversial. This article reviews and analyzes what is known about the role of Treg cells and anti-inflammatory cytokines in psoriasis. PMID- 29589641 TI - Cutaneous squamous cell carcinoma complicating hidradenitis suppurativa: a review of the prevalence, pathogenesis, and treatment of this dreaded complication. AB - Hidradenitis suppurativa (HS) is a chronic and debilitating skin disorder characterized by the formation of painful abscesses, draining sinus tracts, and scarring, predominantly in skin folds such as the axillae and the perineum. The exact prevalence of HS is unknown because the disease is often underreported, but it has been estimated to be as high as 4.1%. HS is three times more prevalent in women than in men. Various comorbidities have been associated with HS, including inflammatory bowel disease and squamous cell carcinoma (SCC). The transformation of chronic HS to SCC is often considered the most severe complication of HS. The prevalence of SCC associated with HS is approximately 4.6%, and is more common among men. It is likely that the chronic irritation and inflammation characteristic of HS drive the malignant transformation to SCC, and recent work has identified other potential risk factors for this malignant transformation, including human papillomavirus (HPV) infection and tobacco use. Treatment modalities have expanded in recent years to include triple antibiotic therapy, immunomodulatory biologic agents, laser therapy, and surgical excision. Knowledge of these comorbid associations of HS, especially the malignant transformation to SCC, is highly important for the management and follow-up of this chronic disease.

A 9-year-old boy presented with sparse hair over his body and with a history of losing his hair soon after birth. Multiple skin-colored papules were observed over the scalp. A biopsy from a papule showed keratinous cysts in the dermis and the absence of hair follicles. A diagnosis of congenital APL was made after vitamin D-dependent rickets was excluded. This case highlights congenital APL as a cause of total alopecia. PMID- 29589645 TI - Chronic peripheral edema in a patient with rheumatoid arthritis. AB - Chronic peripheral edema is a very common yet underestimated problem. It is of utmost importance to investigate various possible causes and understand the pathophysiological mechanisms of chronic peripheral edema in order to determine the optimal treatment. This case report presents the case of a polymorbid patient with a deformity-causing type of rheumatoid arthritis and a 1-year history of progressive symmetrical peripheral edema. Based on an extensive diagnostic investigation, the patient was diagnosed with a combined form of chronic peripheral edema comprised of true lymphedema, which was confirmed by lymphoscintigraphy, and filtration edema due to muscular inactivity. Edema as a side effect of tocilizumab was also suspected. PMID- 29589646 TI - Fat and MEAT. A rare benign lesion of adipose tissue. AB - The concept of mobile tumors was introduced by Shelley and Shelley in 2006. They coined the term abacus tumor. Mobile lipomas have been described in the literature as an example of abacus tumors. This was later questioned by Burgdorf et al., who performed comparative studies in cattle. They suggested the term mobile encapsulated adipose tissue (MEAT) for lipoma-like mobile lesions in cattle and people. We report two more cases of MEAT in adult patients and discuss the literature on this unusual subject. PMID- 29589647 TI - Primary systemic amyloidosis with skin and cardiac involvement: a case report AB - Primary systemic amyloidosis is characterized by the deposition of insoluble monoclonal immunoglobulin light chains in various tissues and is usually associated with an underlying plasma cell dyscrasia. In the early stage of the disease, dermatological findings can be the only manifestation, as opposed to organ involvement in the later stages. A dermatologist can diagnose amyloidosis early with a skin biopsy stained with Congo red dye and other appropriate investigations. This case report describes a female patient with primary systemic amyloidosis confirmed histologically from a skin biopsy. When the diagnosis was established, cardiac involvement and monoclonal gammopathy were already present. Treatment with bortezomib and dexamethasone was initiated; due to side effects, the treatment was later switched to lenalidomide, which was better tolerated.

AB - Non-viral gene delivery is a safe technique to release sustained physiologic dosages of bone morphogenetic protein (BMP). Co-delivery of multiple BMPs can result in the formation of more potent BMP heterodimers. In this study, non-viral co-delivery of BMP-2/6 and BMP-2/7, as a mean to produce heterodimers, was assessed. Goat MSCs were non-virally transfected with plasmid DNA encoding BMP isoforms (pBMP) known to be relevant for osteogenesis: BMP-2, -6 or -7. As a result, BMP-2, -6 and -7 were produced and detectable for up to 14 d and their combined delivery (pBMP-2 with pBMP-6 or pBMP-7) was used to create BMP-2/6 and BM-2/7 heterodimers. Formation and secretion of the heterodimer proteins was validated by sandwich enzyme-linked immunosorbent assay (ELISA). Produced BMPs and heterodimers were biologically active, as confirmed by differentiation of reporter cells and MSCs. To assess bone formation, transfected MSCs were seeded on to ceramic scaffolds and implanted subcutaneously into nude mice. Bone formation was significantly enhanced in the pBMP-2/6 condition and a trend for more bone formation was observed in the pBMP-2/7 and pBMP-6 homodimer condition. No bone was found in the pBMP-2, pBMP-7 or control condition. In conclusion, simultaneous delivery of pBMP-2 with pBMP-6 or -7 resulted in the production of heterodimers that were beneficial for bone formation as compared to BMP homodimers. Combination of BMP sequences could reduce the need for high BMP protein dosages and might enhance prolonged availability of the growth factors. PMID- 29589651 TI - ? PMID- 29589650 TI - Relaxation techniques for pain management in labour. AB - BACKGROUND: Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute to the popularity of complementary methods of pain management. This review examined currently available evidence on the use of relaxation therapies for pain management in labour. This is an update of a review first published in 2011. OBJECTIVES: To examine the effects of mind-body relaxation techniques for pain management in labour on maternal and neonatal well-being during and after labour. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register (9 May 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 5 2017), MEDLINE (1966 to 24 May 2017), CINAHL (1980 to 24 May 2017), the Australian New Zealand Clinical Trials Registry (18 May 2017), ClinicalTrials.gov (18 May 2017), the ISRCTN Register (18 May 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (18 May 2017), and reference lists of retrieved studies. SELECTION CRITERIA: Randomised controlled trials (including quasi randomised and cluster trials) comparing relaxation methods with standard care, no treatment, other non-pharmacological forms of pain management in labour or placebo. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We attempted to contact study authors for additional information. We assessed evidence quality with GRADE methodology. MAIN RESULTS: This review update includes 19 studies (2519 women), 15 of which (1731 women) contribute data. Interventions examined included relaxation, yoga, music and mindfulness. Approximately half of the studies had a low risk of bias for random sequence generation and attrition bias. The majority of studies had a high risk of bias for performance and detection bias, and unclear risk of bias for, allocation concealment, reporting bias and other bias. We assessed the evidence from these studies as ranging from low to very low quality, and therefore the effects below should be interpreted with caution.RelaxationWe found that relaxation compared to usual care provided lowered the intensity of pain (measured on a scale of 0 to 10 with low scores indicating less pain) during the latent phase of labour (mean difference (MD) -1.25, 95% confidence interval (CI) 1.97 to -0.53, one trial, 40 women). Four trials reported pain intensity in the active phase; there was high heterogeneity between trials and very low-quality evidence suggested that there was no strong evidence that the effects were any different between groups for this outcome (MD -1.08, 95% CI -2.57 to 0.41, four trials, 271 women, random-effects analysis). Very low-quality evidence showed that women receiving relaxation reported greater satisfaction with pain relief during labour (risk ratio (RR) 8.00, 95% CI 1.10 to 58.19, one trial, 40 women), and showed no clear benefit for satisfaction with childbirth experience (assessed using different scales) (standard mean difference (SMD) -0.03, 95% CI -0.37 to 0.31, three trials, 1176 women). For safety outcomes there was very low-quality evidence of no clear reduction in assisted vaginal birth (average RR 0.61, 95% CI 0.20 to 1.84, four trials, 1122 women) or in caesarean section rates (average RR 0.73, 95% CI 0.26 to 2.01, four trials, 1122 women). Sense of control in labour, and breastfeeding were not reported under this comparison.YogaWhen comparing yoga to control interventions there was low-quality evidence that yoga lowered pain intensity (measured on a scale of 0 to 10) with low scores indicating less pain) (MD -6.12, 95% CI -11.77 to -0.47, one trial, 66 women), greater satisfaction with pain relief (MD 7.88, 95% CI 1.51 to 14.25, one trial, 66 women) and greater satisfaction with childbirth experience (MD 6.34, 95% CI 0.26 to 12.42 one trial, 66 women (assessed using the Maternal Comfort Scale with higher score indicating greater comfort). Sense of control in labour, breastfeeding, assisted vaginal birth, and caesarean section were not reported under this comparison.MusicWhen comparing music to control interventions there was evidence of lower pain intensity in the latent phase for women receiving music (measured on a scale of 0 to 10 with low scores indicating less pain) (MD -0.73, 95% CI -1.01 to -0.45, random-effects analysis, two trials, 192 women) and very low-quality evidence of no clear benefit in the active phase (MD -0.51, 95% CI -1.10 to 0.07, three trials, 217 women). Very low-quality evidence suggested no clear benefit in terms of reducing assisted vaginal birth (RR 0.41, 95% CI 0.08 to 2.05, one trial, 156 women) or caesarean section rate (RR 0.78, 95% CI 0.36 to 1.70, two trials, 216 women). Satisfaction with pain relief, sense of control in labour, satisfaction with childbirth experience, and breastfeeding were not reported under this comparison.Audio analgesiaOne trial evaluating audio analgesia versus control only reported one outcome and showed no evidence of benefit in satisfaction with pain relief.MindfulnessOne trial evaluating mindfulness versus usual care found an increase in sense of control for the mindfulness group (using the Childbirth Self-Efficacy Inventory) (MD 31.30, 95% CI 1.61 to 60.99, 26 women). There is no strong evidence that the effects were any different between groups for satisfaction in childbirth, or for caesarean section rate, need for assisted vaginal delivery or need for pharmacological pain relief. No other outcomes were reported in this trial. AUTHORS' CONCLUSIONS: Relaxation, yoga and music may have a role with reducing pain, and increasing satisfaction with pain relief, although the quality of evidence varies between very low to low. There was insufficient evidence for the role of mindfulness and audio-analgesia. The majority of trials did not report on the safety of the interventions. Further randomised controlled trials of relaxation modalities for pain management in labour are needed. Trials should be adequately powered and include clinically relevant outcomes such as those described in this review. PMID- 29589652 TI - [When hair starts to fall out]. AB - Hair loss causes physical and psychological distress and represents a common motive of consultation both in general practice and dermatology. Causes of hair loss are highly diverse and can lead to a challenging diagnosis, which can delay its management. Knowledge of the main causes and their different mechanisms are thus necessary in order to optimize both the diagnosis and treatment. The purpose of this paper is to describe the main causes of hair loss in order to improve its diagnosis and management. PMID- 29589653 TI - [Repurposing of betablockers in dermatology]. AB - Betablockers are used for decades in the treatment of cardiovascular diseases. Recently, the repurposing of the wide spectrum betablocker propranolol revolutionized the infantile hemangioma management. Besides, betablockers have been shown to significantly improve the prognosis of melanoma patients. Blocking the adrenergic receptors blocks the stress-induced tumorigenic pathways. Propranolol inhibits melanoma by downregulating the tumor angiogenesis but also tumor cell proliferation, invasiveness and local immune suppression. These antitumor effects have been observed in other cancers. The repurposing of propranolol has already changed the practice of pediatricians and dermatologists and may soon help oncologists treat various cancers.

AB - Alterations of the nail unit in children may be congenital or acquired, may be an isolated finding or part of a systemic problem or a syndrome. In this article we describe the most common childhood nail changes and underscore some important clinical clues that should motivate further investigations. Moreover we give a brief overview of the management of these nail pathologies. PMID- 29589655 TI - [Emerging systemic treatments of atopic dermatitis]. AB - Atopic dermatitis (AD) is the most common inflammatory dermatitis for which molecular research is currently extending. Mostly mediated by helper T lymphocytes type 2 (Th2), it seems that Th22 and Th17 can also be involved on a smaller scale. An IL-4/IL-13 inhibitor, key cytokines of the Th2 pathway, has recently been recognized as a new treatment for AD and has opened the field to multiple clinical trials for other selective immunosuppressants such as biologics and small molecules. These advances make us hope for the development of more effective and better-tolerated treatments than conventional immunosuppressants. In addition, they promise to advance the knowledge of this complex inflammatory pathology and its clinical subtypes. PMID- 29589656 TI - [What's new in the management of atopic dermatitis in children and adolescents ?] AB - A better understanding of the atopic dermatitis (AD) pathogenesis and the need for more efficient and safer treatments in severe AD promoted the development of new therapies. Several underwent and are still undergoing clinical trials, but due to safety reasons, they include mainly adults for now. AD is however predominant in childhood with a prevalence 20 % in children compared to only 5 % in adults. Regarding the pediatric population, the new pipeline relies on two selective immunosuppressive agents, notably crisaborole (phosphodiesterase-4 inhibitor) and dupilumab (IL-4 and IL-13 inhibitor). In order to strengthen the medical treatment, therapeutic patient education plays a supportive role in the global approach, allowing an optimized care. The Lausanne model of the Pediatric Dermatology Unit is described in this article. PMID- 29589657 TI - [Extracorporeal photopheresis]. AB - During the treatment of extracorporeal photopheresis (ECP), white blood cells are collected by apheresis and exposed to ultraviolet A after incubation with 8 methoxypsoralen. Although ECP was first developed for cutaneous T cell lymphoma, it has shown promising efficacy in a number of other serious conditions, like acute and chronic graft-versus-host disease, lung and cardiac transplant rejection and other autoimmune diseases. The ECP has been used for thirty years in some specialized centers but remains unknown to most of the physicians. The aim of this article is to review the practical aspects, the mode of action and the current indications of ECP. PMID- 29589659 TI - ? PMID- 29589660 TI - ?

A pilot study AB - The present study sought to test oral-care products available on the Swiss market, such as toothpastes and gels, with respect to the protection of enamel against erosive tooth wear. A total of 56 enamel specimens were divided into 7 groups (n = 8): F-TP = Migros Budget Anti-Caries Toothpaste (Negative Control); F+Sn3500-TP = Elmex Erosion Protection Toothpaste (Positive Control); F-TP + F+Oligopep-Gel = Migros Budget Anti-Caries Toothpaste + Emofluor Protect Gel Professional; F+Sn3120-Gel = Emofluor Gel Intensive Care; F+Oligopep-TP = Candida Protect Professional Toothpaste; F+Sn1260-TP = Emoform-F Protect Toothpaste; and F+Sn3440-TP = Sensodyne Repair & Protect Toothpaste. The specimens were incubated in artificial saliva for 30 min and then brushed in a toothbrushing machine (10 s brushing; total 2 min exposure to the product). After the toothbrush abrasion, the specimens were rinsed, dried and submitted to an erosive challenge (2 min; 1% citric acid; pH 3.6). This sequence was repeated 4 times, and the total enamel surface loss was calculated using indentation measurements before and after the brushing period. All groups presented progressive surface loss throughout the experiment; after 4 cycles, total surface loss values ranged from 0.11 um (F+Sn3120-Gel) to 0.89 um (F+Sn1260-TP). Regarding the total surface loss values (median; interquartile range), F-TP (0.54; 0.42-0.59) presented no significant differences compared to any of the other groups. F+Sn3500-TP (0.33; 0.30-0.40), F TP + F+Oligopep-Gel (0.34; 0.29-0.42) and F+Sn3120-Gel (0.11; 0.09-0.15) presented lower surface loss than F+Oligopep-TP (0.75; 0.59-0.98), F+Sn1260-TP (0.89; 0.68-1.13) and F+Sn3440-TP (0.69; 0.66-0.78). Conclusion: Although some of the oral-care products containing stannous ions or oligopeptide-104 presented numerically lower SL values, they did not present significantly better protection than a regular fluoride toothpaste. The gels showed a general trend of better enamel protection against ETW.

It is in light of the increasingly prevalent use of CBCT, particularly in a primary dental care setting, that the goal of this review is to investigate what evidence-based guidance is available to the clinician to justify and reduce radiation risk of this higher dose imaging modality while maintaining diagnostically acceptable images. To this end, the literature on radiation dose and related patient risk was comprehensively investigated, before an analysis of the ways in which dose can be optimized and the implications that optimization has on image quality was discussed. Finally, although it is accepted that CBCT has the potential to improve diagnosis, it is uncertain if its use has positive ramifications on issues of diagnostic efficacy, including clinical decision-making and patient outcome. In order to investigate these issues, the levels of evidence of the existing studies and their validity were assessed. On review of the available literature, it is evident that there is limited practical advice available to dentists regarding dose optimization and any existing protocols may not be readily transferable to every CBCT machine, the manufacturers' role is not often conducive to dose limitation and that the bulk of evidence is at lower levels of evidence. Furthermore, there is minimal supporting evidence to suggest an impact of CBCT on diagnostic thinking and consequent choice of treatment and no evidence of a positive effect of CBCT on patient outcome. PMID- 29589668 TI - Percutaneous tricuspid valve replacement: orthotopic and heterotopic valves. AB - The tricuspid valve has long been described as the "forgotten valve", leaving tricuspid valve disease relatively neglected. However, the number of people in the United States affected by severe tricuspid regurgitation is growing. Isolated surgery for severe tricuspid regurgitation in the setting of right ventricular heart failure carries a high mortality risk, and therefore, attention to corrective therapies has increased. Because of the different etiologies for tricuspid regurgitation, multiple percutaneous transcatheter options for tricuspid valve repair for severe regurgitation are being studied and have been developed, including annuloplasty systems, leaflet and coaptation devices, vena caval (heterotopic) valve implantations, and tricuspid valve (orthotopic) replacement. In this paper, we review the heterotopic and orthotopic tricuspid valve transcatheter options for severe tricuspid regurgitation. PMID- 29589669 TI - Percutaneous coronary intervention risk scores. AB - Percutaneous coronary interventions in patients at high clinical risk with anatomical complexity is one of the most important topics in interventional cardiology. The development of materials and techniques allowed the interventional cardiologist to be able to treat virtually any coronary lesion. The patient's evaluation with clinical and anatomic risk scores allow the physicians to choose the best therapeutic strategy for each individual patient. PMID- 29589670 TI - Standardization of Impella(r)-assisted patient management. AB - The presence of high-risk features on candidates to percutaneous revascularization is increasingly leading to Impella(r)-assisted procedures (IAPs). While IAPs are safe and effective procedures, they still require managing a degree of complexity. Clinicians often rely on their ability to recall every step of operative procedures. However, during stressful situations, levels of cognitive function are compromised leading to planning and execution failures and decreased safety. Many high-risk activities such as aviation, aerospace industry, and nuclear plants have been using protocols, standardized procedures and checklists for many years. The purpose of the present article is to make a proposal for the standardization of ordinary medical activities required outside the Cath Lab for the management of patients before and after IAPs. PMID- 29589671 TI - Tricuspid valve regurgitation: epidemiology and pathophysiology. AB - Compared with the vast literature concerning the prevalence, pathophysiology, and outcome of left valvular disease, the data concerning tricuspid regurgitation (TR) is very limited. In this review we summarized the present data concerning these important issues. We show that TR is as prevalent as aortic stenosis in the community, with increasing prevalence with age, and much more common in women. We review the present knowledge concerning the pathogenesis of TR, focusing on functional TR. We show that functional TR is multifactorial, resulting from both RV remodeling and pulmonary hypertension, and/or atrial fibrillation resulting in right atrial dilatation. We demonstrate that RV remodeling, mostly in the mid segment, will result in tethering. On the other side, right atrial remodeling will mostly result in pure annular dilatation and loss of valvular/annular coverage reserve. Finally, due to the heterogeneous nature of TR we review the outcome data for each presentation of TR and show that in most contexts TR is associated with very poor outcome, even when adjusted for left ventricular systolic, and diastolic function, pulmonary pressure, and RV dysfunction. PMID- 29589672 TI - The Synergy stent in high-bleeding risk patients: why design matters. AB - Antithrombotic management after percutaneous coronary intervention is based on dual antiplatelet therapy (DAPT), that has unequivocally shown to reduce the risk of recurrent ischemic events at cost of an important risk of bleeding. In order to balance ischemic and bleeding risks, DAPT duration should be based on patients and lesions features as well as stent type. Based on these considerations, patients at high bleeding risk (HBR) undergoing PCI represent a challenging subgroup. The Synergy stent (Boston Scientific, Marlborough, MA, USA) is a new generation everolimus-eluting stent with a biodegradable polymer coating, presenting several features that have the potential to reduce acute and long-term thrombogenicity and the subsequent need for DAPT. The aim of this manuscript is to review the evidence about the impact of stent design on the optimal antithrombotic strategy in HBR patients and the potential role of the Synergy BP EES in this relevant population. PMID- 29589673 TI - Cardiac rehabilitation after STEMI. AB - Cardiac rehabilitation is the most important evidence-based intervention for secondary prevention after STEMI, nevertheless, only a minority of patients may access to a cardiac rehabilitation program. In this review the priority criteria for admission to cardiac rehabilitation and the main barriers that limit a larger involvement of the patients are discussed. Among the components of cardiac rehabilitation exercise is crucial and a tailored exercise training program and a tight monitoring of adherence to lifestyle recommendations are mandatory. Finally, the development of light cardiac rehabilitation pathways and home programs may allow a larger diffusion of outpatient programs. In conclusion, the participation to a cardiac rehabilitation program following STEMI is about 25-35% in western countries, and only 15% in Italy. Stressing the importance of cardiac rehabilitation participation is crucial for all post-myocardial infarction patients, particularly for the vulnerable socioeconomic populations. PMID- 29589674 TI - Reperfusion in STEMI patients: still a role for cardioprotection? AB - Ischemic heart disease remains a leading cause of death worldwide, responsible for an estimated 17.5 million deaths in 2012. Mortality from ST-elevation myocardial infarction STEMI have decreased over the last 3 decades. However, despite the success of reperfusion therapy by primary percutaneous coronary intervention (PPCI) or thrombolysis, STEMI is still of significant concern. A recent patient-level meta-analysis emphasized the pivotal importance of infarct size within 1 month after PPCI as a determinant of all-cause mortality and hospitalization for heart failure at 1 year. Although timely and complete reperfusion is the most effective way of limiting infarct size (IS) and subsequent ventricular remodeling, reperfusion per se adds an additional component of irreversible injury to the myocardium (known as ischemia/reperfusion injury, IRI), and the coronary circulation and it contributes to final infarct size. The prevention and treatment of lethal IRI and coronary microvascular dysfunction pose a continued and formidable barrier to successful myocardial perfusion as opposed to establishing patency of the epicardial infarct-related artery (IRA), and in this context the need for additional cardioprotective strategies to reduce IS and coronary microvascular dysfunction remains the 'last frontier' of reperfusion therapy. PMID- 29589675 TI - Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: risk factors for morbidity and postoperative outcome. AB - BACKGROUND: Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) represents a treatment option for peritoneal surface malignancies. Even if it has been reported that this new approach improved survival of selected patients, it's still associated with high morbidity and mortality rates. METHODS: From October 1995 to December 2017, over 450 patients patients affected by peritoneal carcinomatosis (PC) underwent in our Institute to CRS associated with HIPEC. For this preliminary analysis we considered 300 patients presenting PC of different origin: pseudomyxoma peritonei (PMP, n = 98), epithelial ovarian cancer (EOC, n = 87), peritoneal mesothelioma (DMPM, n = 49) and colorectal cancer (CRC, n = 66). Postoperative morbidity and mortality were studied in order to identify possible risk factors. RESULTS: The morbidity rate was 36.3% in all procedures (109/300). According to Dindo - Clavien Classification, 67 cases (22.3%) were associated with grade I-II complications and 35 cases(11.7%) with grade III-IV. Surgical and medical complication rates were 8.3% (25/300) and 11.3% (34/300), respectively. The mortality rate was 2.3%. Reoperation was needed in 28 patients (9.3%). The operative time, the number of anastomosis, of peritonectomy procedures, of visceral resections performed and the PCI value resulted the most statistically significant factors influencing postoperative morbidity and mortality. CONCLUSIONS: The risks of perioperative morbidity and mortality after CRS and HIPEC are analogous to any other major gastrointestinal surgery. CRS and HIPEC should remain a treatment option for highly selected patients in whom a curative or life prolonging treatment is a pursuit and should be performed in high volume specialized institutions.

PMID- 29589678 TI - Breast conservation following neoadjuvant therapy for breast cancer. PMID- 29589679 TI - Axillary surgery in breast cancer: the beginning of the end. AB - Axillary surgery in breast cancer patients has shifted from more extensive to minimalist approaches with re-evaluation of the risks versus benefits of available treatment options which are increasingly tailored to individual patient characteristics. A radical axillary node dissection is rarely indicated nowadays due to several factors including screening with detection of small node negative cancers, introduction of targeted node sampling, less reliance on information from nodal staging for adjuvant therapy decision making and evidence that non surgical treatments such as systemic therapies (chemotherapy, hormonal therapy, biological therapy) together with radiotherapy can safely treat low burden axillary disease. Sentinel lymph node biopsy (SLNB) alone with omission of further axillary surgery for nodal macrometastases (>2 mm) might be sufficiently extirpative to achieve local control when combined with adjuvant treatments. There remain unanswered questions on the safety of SLNB post chemotherapy in patients with biopsy-proven nodal disease at presentation and whether omission of axillary node dissection is feasible in selected cases. Emerging evidence suggests that a complete radiological response with removal of at least 3 nodes (including clipped nodes at time of biopsy) can yield false negative rates of <10% and be a safe option. New technologies involving percutaneous biopsy of sentinel nodes under radiological guidance are under investigation and could potentially replace surgical staging of the axilla in the future. Moreover, omission of any type of node biopsy might be a potential option in more favorable tumors and could herald the beginning of the end for histological axillary sampling in selected cases. PMID- 29589680 TI - Management of ductal carcinoma in situ in the modern era. AB - Ductal carcinoma in situ (DCIS) has been the subject of much controversy since the advent of population based breast screening programs. An increasing number of asymptomatic women are being diagnosed with this condition and there is uncertainty over the best treatment algorithm for this condition if treatment is to be considered at all. Different subtypes of DCIS show innate differences in developmental pathways and biological behavior. This is not only determined by pathological subtypes but there is increasing understanding of molecular biomarkers related to DCIS progression. The ultimate management aim is to identify a subgroup of patients in whom DCIS will not progress to invasive disease such that they can avoid morbidity from surgical and adjuvant therapies. This has to be balanced by the potential risk of undertreatment of patients in whom DCIS is likely to progress to invasive cancer and hence a reduced life expectancy. Results of current ongoing prospective randomized trials assessing the safety of omitting surgery for what is considered to be low risk DCIS are eagerly awaited for by patients and clinicians. However the definition of what is considered to be "low risk" DCIS is still to be ascertained. PMID- 29589681 TI - ? AB - The drug industry has a poor public image. Although its role is to treat disease, it has a poorer reputation than cigarette makers or the automotive industry. This situation must be analysed from three overlapping points of view: 1) the complexity of a market, in which most of the costs are hidden; 2) the difficulty of a connected society to organize debates on political questions related to basic values, and finally 3) the pervading distinction between morality and profits. This clarification might help the industry to become a fully fledged actor in the field of healthcare in order to participate in the improvement of the healthcare offer for the population.

AB - INTRODUCTION: Organizational culture, a frequently ignored concept, affects job satisfaction and productivity in organizations. OBJECTIVE: To determine the factors associated with the strength of organizational culture (OC) in Mono / Couffo regional hospital in Lokossa in Benin. METHODS: This cross-sectional and analytical study involved 121 workers of Mono/Couffo hospital in March 2015. Data on the strength of OC was collected using a questionnaire based on the validated tool proposed by Cameron and Quinn (2006). Logistic regression was performed to explore the nature of the relationship between the independent variables and OC using Odds ratios. RESULTS: 62% of the surveyed subjects had a positive perception of organizational culture. This perception was statistically associated with managerial factors (moral support of workers and type of relationship with the executive staff). The risk of perceiving a low strength of OC was sixfold higher OR = 3.78, 95% CI (1.08 - 13.22) among subjects who felt they did not have moral support from executive staff than in those who perceived this moral support. The risk of perceiving a weak OC was higher among subjects who considered relations with the staff to be uncordial [OR = 14.32, 95% CI (4.35 - 47.11)] compared to those who considered these relations to be cordial. CONCLUSION: Human resource management factors were more closely associated with the strength of organizational culture. Hospital managers should pay more attention to these factors in their hospitals to promote better institutional performance.

AB - INTRODUCTION: To determine the prevalence and determinants of coexistence of maternal overweight or obesity and stunted children (DBM / SCOM) in south-western Benin households. METHODS: This cross-sectional study was carried out in June 2015 on 357 mother-child pairs randomly selected by a two-stage sampling technique in the city of Come and its surroundings. Data on socio-economic factors, family, health care, dietary quality were collected by questionnaires, observation and documentary review. Anthropometric measurements were performed in mothers and children. A logistic regression analysis model was used to search for determinants of the coexistence of the two aspects of malnutrition. RESULTS: 19.3% of mothers were overweight and 5.7% were obese. 46% of children were stunted. The prevalence of DBM / SCOM was 11.5%. The main factors associated with DBM/SCOM were the child's age, the mother's occupation, ethnicity, social status and educational level, and the size, economic level, transportation means and food insecurity of the household. CONCLUSION: A high frequency of the coexistence of maternal overweight or obesity and stunting was observed in Come households. Interventions based on the identified determinants are needed to act simultaneously on the double burden of malnutrition in Come.

AB - INTRODUCTION: Motorcycle taxis occupy a major place in urban transport. Motorcycle taxi drivers are exposed to occupational risk factors (ORF) including air pollution. The objective of this study was to evaluate these ORF among motorcycle taxi drivers and their perceptions of air pollution. METHODS: This mixed study was conducted on motorcycle taxi drivers in Cotonou. The qualitative study was based on focus groups concerning 16 items from the Participatory Occupational Risk Screening Guide (DEPARIS) until saturation and after triangulation of data. The quantitative study consisted of administering a questionnaire addressing socioeconomic and demographic characteristics, cardiopulmonary diseases, and perception of air -pollution risk factors among 397 Cotonou motorcycle taxi drivers. RESULTS: Drivers perceived poor road conditions, effort and handling, and lack of social security as unsatisfactory ORF. Their mean age was 40.95 +/- 8.75 years and 45.84% had primary -education. They had been working as motorcycle taxi drivers for an average of 134.95 +/- 101.53 months with an average income of FCFA 3138 +/- 1238. These occupational factors were significantly associated with cardiopulmonary disorders, observed in 63.2% of drivers. Less than 1/3 of drivers felt that air pollution affected their personal health. CONCLUSION: Motorcycle taxi drivers have a poor perception of ORF and the severity of exposure to air pollution in this occupation. There is a need to take action to promote the health of this population. PMID- 29589685 TI - [Impact of children with multiple disabilities on families in Abidjan]. AB - INTRODUCTION: A child's multiple disabilities have a major impact on families in both developed and developing countries. In Cote d'Ivoire, very few data are available concerning the real experiences of families of children with multiple disabilities. The objective of this study was to improve our knowledge of the impact of children with multiple disabilities on families in Cote d'Ivoire. METHODS: A qualitative study was conducted among the families consulting the Child Guidance Centre of the National Institute of Public Health in Abidjan. Data were collected in May 2015 by semi-structured individual interviews with mothers of children with multiple disabilities. RESULTS: Twenty mothers of multiply disabled children between the ages of 2 and 14 years were interviewed. The child's multiple disability was found to have a negative impact on finances, health, and social life. Health check-ups, treatment and transport are the main additional costs. Mothers suffer from insomnia, fatigue, back pain and anxiety and were often held responsible for their child's disability. A disabled child was a source of discord in several couples and a cause of school drop-out in some families.This study partially addresses the experiences of families with children with multiple disabilities. It confirms the results of several other studies, highlighting the vulnerability and social dysfunction of these families. CONCLUSION: The presence of a child with multiple disabilities in a family is a source of psychological, financial and social upheaval. This study raises questions about the impact of multiple disabilities on the whole family and a more detailed analysis of economic aspects.

AB - INTRODUCTION: Multiple sclerosis is a neurological disease that induces limitation of bodily performance. It has a major impact on the work and social life of affected persons because the patient's disability, often in the absence of visible symptoms, is o source of incomprehension in a society marked by the neoliberal dogma of performance. Patient associations often provide support for patients in their trajectory. OBJECTIVE: The aim of this research was to identify how the principles of neoliberalism manifest themselves in the discourse of multiple sclerosis subjects, to understand the effects of neoliberal integration, and to clarify the role played by the association involvement in the trajectories of life. METHODS: This qualitative study was based on 30 individual interviews and 4 group interviews with patients, as well as 23 observations of patient group meetings and focus groups. Ten people met in interviews also kept a mini-diary, in order to record their daily involvement in a patient association. Data were analysed thematically, initially independently then by cross-linked AtlasTi software. RESULTS: The association constitutes two forms, practical and ideological, an illustration of the resistance to neoliberalism, particularly in the form of individual and collective responsibilities. However, to a certain extent, it also recreates performance spaces. CONCLUSION: From a practical point of view, this research re-affirms the need to create collective activities to accompany people with chronic illness.

AB - OBJECTIVES: The prevalence of breastfeeding in France is lower among deprived women than in the rest of the population. The Haute-Normandie region is severely affected by deprivation, especially among women. PRIMARY OBJECTIVE: To describe breastfeeding promotion in deprived women living in Haute-Normandie. Secondary objectives: to describe the prevalence of breastfeeding and identify barriers to breastfeeding in the same population. METHODS: This cross-sectional observational study was carried out in Haute-Normandie between March and June 2015, in three steps: 1) mailing questionnaires to actors working with deprived women, 2) analysis of child health certificates and 3) sociological interviews with 15 deprived women. RESULTS: Only 4 of the 29 responding structures had implemented actions to promote breastfeeding among deprived women, with positive feed-back. Barely half of all deprived women had initiated breastfeeding in Haute-Normandie (Eure: 50%, Seine-Maritime: 54%). Finally, the same factors usually known to affect breastfeeding and its duration were also identified among deprived women living in Haute-Normandie. CONCLUSION: Guidelines for actions to support breast feeding among deprived mothers have been developed to guide local policies designed to reduce social inequalities in health in Haute-Normandie. PMID- 29589689 TI - [Interventions for smoking cessation among low socioeconomic status smokers: a literature review]. AB - INTRODUCTION: In most western countries, smoking appears to be highly differentiated according to socio-economic level. Two systematic reviews published in 2014 showed that most of the recommended interventions for smoking cessation, particularly individual interventions, tend to increase social inequalities in health. An analysis of the most recent literature was carried out in order to provide policy makers and stakeholders with a set of evidence on the modalities of interventions to encourage and help disadvantaged smokers quit smoking. METHODS: This review was based on articles published between January 2013 and April 2016. Only studies conducted in European countries or countries in stage 4 of the tobacco epidemic (USA, Canada, Australia, New Zealand) were included. Selected articles were double-screened. RESULTS: Twenty-three studies were identified, including evaluation of media campaigns, face-to-face behavioural support, phone- and web-based support or awareness of passive smoking among children. Some interventions adapted to precarious populations have been shown to be effective.

The organisational requirements (OR) of the Head Nurse (HN) are often centered on the operational level, to the detriment of the other two levels. This difficulty is due to the organisation which presents limited political, cognitive and pragmatic levels of rationality.The aim of this study was to identify the impact of a third party in relation to the organisation and its effect on the HN's OR. An educational device places HN students in the position of a third party to allow them to work on an organisational problem delegated by a HN. The research intervention followed 17 projects over a period of one year.Intervention by a third party legitimised the problem by recognizing the difficulties in nursing and reconfiguring relations between healthcare professionals in a political dimension. The methods employed by the third party reassured the HN and completed their knowledge, placing particular focus on the importance of methodology and managerial posture. In practice, the third party supported the HN's power to act and coordinate the various members of the team. The third party contributes to the development of the HN's OR and completes certain limits of the HN's rationality. Nevertheless, difficulties still remain in the development of practices outside the medical team, limiting the extension to other services.A unit managerial support, a collective schedule and open spaces of discussion are recommended to bring structure and support to the OR.

AB - INTRODUCTION: "J'aime manger, j'aime bouger, le guide nutrition pour les adolescents", ("I love to eat and move, the nutrition pamphlet for teenagers"), which is one of the eight information guides of the French Nutritional and Health Programme, is distributed annually by Sante publique France, the national public health agency, to 8th grade students by their biology teachers. The aim of this study was to assess the impact of this dissemination plan and the way 8th grade students and biology teachers perceive the pamphlet. Teenagers' knowledge of the French Nutritional and Health Programme's recommendations was also assessed. METHODS: This study was based on a mixed method and was conducted in 2015 on 432 8th grade students by face-to-face interviews at home and 20 8th grade biology teachers interviewed individually or during focus groups. RESULTS: The pamphlet obtained a recognition score of 40% among young people, who mostly saw it during a course at high school. 30% of teenagers reported having read or only skimmed through it and more than three-quarters reported that they liked the pamphlet. Teenagers and teachers found the pamphlet clear and accessible and globally appreciated the content, but they considered that it could be modernized. CONCLUSION: Systematic distribution of the guide to students of a specific school grade is an efficient strategy to reach a maximum number of young people. It should be continued in the future. Modernization of the guide and improved support to teachers to distribute the guide could improve the performance of the programme.

AB - INTRODUCTION: For the last forty years, patients have been encouraged to take part in their care and to participate in improving the quality and safety of care. This phenomenon requires reflection on the conditions of emergence of this new role and its public health implications, particularly in the field of patient safety. METHODS: A narrative review of the international literature was conducted by searching Medline, Cairn and Persee databases. RESULTS: The database query identified 2,206 documents, 106 of which were included in the analysis. The emergence of the patient-actor is linked to sanitary crises and promoted by patient associations in the field of patient safety such as le Lien. This movement induces a transformation of the patient's role beyond the theme of patient safety: it revolutionizes the patient's contribution to the health system. CONCLUSION: This narrative review of the literature highlights the way in which health crises have encouraged the emergence of a new actor: the patient actor, accompanied by new semantics concerning the power of the patient. The patient occupies a specific place in the field of safety of care. In collaboration with healthcare professionals, the patient must constitute a resource to improve patient safety. The various contributions of patients are described and an analysis of the acceptability of patient participation is proposed.

AB - INTRODUCTION: Overcrowding of emergency services is a widespread problem in western countries. This situation results in negative patient outcomes and influences the quality of care. Standing orders are a possible way to improve the quality and performance of the health system. The aim of this article is to identify, based on a review of the literature, the effects of standing orders initiated by triage nurses in emergency services on the quality of care. METHODS: The quality of care dimensions of the Institute of Medicine (2001) were used as a frame of reference. The integrative review was performed on a selection of articles from Cochrane, CINALH, EMBASE, Medline, PubMed and Google Scholar. A total of 23 articles were selected and analysed. RESULTS: The integrative review documented the effects of standing orders initiated by triage nurses on the six dimensions of quality of care: effectiveness, patient-centeredness, efficiency, timeliness, safety and equity. Standing orders are able to improve the efficiency of care by reducing, among other things, the time to treatment and diagnostic tests. They also reduce the length of stay of patients in emergency services. CONCLUSION: Standing orders initiated by triage nurses in emergency services can have positive effects on the quality of care provided to the patient. Further research with more robust study designs is needed. PMID- 29589697 TI - Exhibition of Instruments. PMID- 29589696 TI - [Palliative care pathways of older patients]. AB - INTRODUCTION: To determine the palliative care pathways of older patients in Sherbrooke, Qc by examining their transfers to other facilities. METHODS: This analysis was conducted by linking 3 databases: emergency department, hospitalizations and nursing homes. The study period ranged from January 2011 to December 2015. SPSS was used for statistical analysis. The study only included palliative care patients. RESULTS: 25% of patients waited less than 7 days for transfer, and 74% waited less than 3 weeks. 64.9% of patients were transferred to a long-term facility for dependent adults (LTF), 15.2% returned home or were transferred to private accommodation, and 15.9% were transferred to an intermediate care facility. One-half of patients subsequently changed facility, mainly those in homes or intermediate care. Palliative care patient bed occupation rates represented 1% of available bed-days and less than 2% of total beds for 86.4% of days. Only 12% of patients returned to hospital within 90 days after discharge. CONCLUSION: The number of beds occupied by palliative care patients does not seem to disrupt the hospital capacity. The majority of the palliative care patients were well managed, as reflected by the low readmission rate. Our results indicate good management of transfers and an adequate supply of long-term care facilities and home services. PMID- 29589699 TI - Exhibition of Specimens.

AB - Developing new electrode materials with high capacity and stability is an urgent demand in electric vehicle applications. Li xSi alloy, as a promising high capacity and Li-containing anode candidate, has attracted much attention. However, the alloy anode suffers severely from intrinsic high chemical reactivity and poor cycling stability in battery fabrication and operation. Here, we have developed a facile coating-then-lithiation approach to prepare lithiated-TiO2 protected Li xSi nanoparticles (Li xSi-Li2O/Ti yO z NPs) as an attractive anode material. The robust lithiated-TiO2 protection matrix not only provides fast electron transport pathways to efficiently improve the electrical conductivity between Li xSi/Si NPs, but also spatially limits the direct solid electrolyte interphase formation on Li xSi/Si cores during cycling. More importantly, this dense coating layer protects most inner Li xSi alloys from ambient corrosion, leading to high dry-air stability. As a result, the resulting Li xSi-Li2O/Ti yO z anode achieves greatly enhanced cycling and chemical stability in half-cells. It maintains capacity of about 1300 mAh g-1 after prolonged 500 cycles at a high current rate of C/2, with 77% capacity retention. In addition, it exhibits excellent dry-air stability, with around 87% capacity retained after exposure to dry air (10% relative humidity) for 30 days. PMID- 29589740 TI - Stokes-Shift-Engineered Indium Phosphide Quantum Dots for Efficient Luminescent Solar Concentrators. AB - Luminescent solar concentrators (LSCs) show promise because of their potential for low-cost, large-area, and high-efficiency energy harvesting. Stokes shift engineering of luminescent quantum dots (QDs) is a favorable approach to suppress reabsorption losses in LSCs; however, the use of highly toxic heavy metals in QDs constitutes a serious concern for environmental sustainability. Here, we report LSCs based on cadmium-free InP/ZnO core/shell QDs with type-II band alignment that allow for the suppression of reabsorption by Stokes shift engineering. The spectral emission and absorption overlap was controlled by the growth of a ZnO shell on an InP core. At the same time, the ZnO layer also facilitates the photostability of the QDs within the host matrix. We analyzed the optical performance of indium-based LSCs and identified the optical efficiency as 1.45%. The transparency, flexibility, and cadmium-free content of the LSCs hold promise for solar window applications. PMID- 29589741 TI - LC/MS/MS Bioanalysis of Protein-Drug Conjugates-The Importance of Incorporating Succinimide Hydrolysis Products. AB - Bioanalysis of antibody-drug conjugates (ADCs) is challenging due to the complex, heterogeneous nature of their structures and their complicated catabolism. To fully describe the pharmacokinetics (PK) of an ADC, several analytes are commonly quantified, including total antibody, conjugate, and payload. Among them, conjugate is the most challenging to measure, because it requires detection of both small and large molecules as one entity. Existing approaches to quantify the conjugated species of ADCs involve a ligand binding assay (LBA) for conjugated antibody or hybrid LBA/liquid chromatography/tandem mass spectrometry (LC/MS/MS) for quantitation of conjugated drug. In our current work for a protein-drug conjugate (PDC) using the Centyrin scaffold, a similar concept to ADCs but with smaller protein size, an alternative method to quantify the conjugate by using a surrogate peptide approach, was utilized. The His-tagged proteins were isolated from biological samples using immobilized metal affinity chromatography (IMAC), followed by trypsin digestion. The tryptic peptide containing the linker attached to the payload was used as a surrogate of the conjugate and monitored by LC/MS/MS analysis. During method development and its application, we found that hydrolysis of the succinimide ring of the linker was ubiquitous, taking place at many stages during the lifetime of the PDC including in the initial drug product, in vivo in circulation in the animals, and ex vivo during the trypsin digestion step of the sample preparation. We have shown that hydrolysis during trypsin digestion is concentration-independent and consistent during the work flow-therefore, having no impact on assay performance. However, for samples that have undergone extensive hydrolysis prior to trypsin digestion, significant bias could be introduced if only the non-hydrolyzed form is considered in the quantitation. Therefore, it is important to incorporate succinimide hydrolysis products in the quantitation method in order to provide an accurate estimation of the total conjugate level. More importantly, the LC/MS/MS-based method described here provides a useful tool to quantitatively evaluate succinimide hydrolysis of ADCs in vivo, which has been previously reported to have significant impact on their stability, exposure, and efficacy. PMID- 29589742 TI - A Novel Redox Precipitation to Synthesize Au-Doped alpha-MnO2 with High Dispersion toward Low-Temperature Oxidation of Formaldehyde. AB - A novel method of redox precipitation was applied for the first time to synthesize a Au-doped alpha-MnO2 catalyst with high dispersion of the Au species. Au nanoparticles (NPs) can be downsized into approximate single atoms by this method, thereby realizing highly efficient utilization of Au element as well as satisfying low-temperature oxidation of formaldehyde (HCHO). Under catalysis of the optimal 0.25% Au/alpha-MnO2 catalyst, a polluted stream containing 500 ppm HCHO can be completely cleaned at 75 degrees C with the condition of a weight hourly space velocity (WHSV) of 60000 mL/(g h). Meanwhile, the catalyst retains good activity for removal of low-concentration HCHO (about 1 ppm) at ambient temperature with a high WHSV, and exhibits a high tolerance to water and long term stability. Our characterization of Au/alpha-MnO2 and catalytic performance tests clearly demonstrate that the proper amount of Au doping facilitates formation of surface vacancy oxygen, lattice oxygen, and charged Au species as an active site, which are all beneficial to catalytic oxidation of HCHO. The oxidation of HCHO over Au-doped alpha-MnO2 catalyst obeys the Mars-van Krevelen mechanism as evidenced by in situ diffuse reflectance infrared Fourier transform spectroscopy.

AB - Energy transfer and interchange are central for fabricating white light-emitting organic materials. However, increasing the efficiency of light energy transfer remains a considerable challenge because of the occurrence of "cross talk". In this work, by exploiting the unique photophysical properties of cucurbituril triggered host-guest interactions, the two complementary luminescent colors blue and yellow for white light emission were independently obtained from a single fluorophore dye rather than energy transfer. Further study suggested that the rigid cavity of cucurbiturils efficiently prevented the aggregation of the dye and improved its thermal stability in the solid state by providing a regular nanosized fence for each encapsulated dye molecule. As a result, a novel macrocycle-assisted supramolecular approach for obtaining solid, white light emitting organic materials with low cost, high efficiency, and easy scale-up was successfully demonstrated.

AB - Understanding the form of Se(IV) co-precipitated with ferrihydrite and its subsequent behavior during phase transformation is critical to predicting its long-term fate in a range of natural and engineered settings. In this work, Se(IV)-ferrihydrite co-precipitates formed at different pH were characterized with chemical extraction, transmission electron microscopy (TEM), and X-ray absorption spectroscopy (XAS) to determine how Se(IV) is associated with ferrihydrite. Results show that despite efficient removal, the mode and stability of Se(IV) retention in the co-precipitates varied with pH. At pH 5, Se(IV) was removed dominantly as a ferric selenite-like phase intimately associated with ferrihydrite, while at pH 10, it was mostly present as a surface species on ferrihydrite. Similarly, the behavior of Se(IV) and the extent of its retention during phase transformation varied with pH. At pH 5, Se(IV) remained completely associated with the solid phase despite the phase change, whereas it was partially released back into solution at pH 10. Regardless of this difference in behavior, TEM and XAS results show that Se(IV) was retained within the crystalline post-aging products and possibly occluded in nanopore and defect structures. These results demonstrate a potential long-term immobilization pathway for Se(IV) even after phase transformation. This work presents one of the first direct insights on Se(IV) co-precipitation and its behavior in response to iron phase transformations. PMID- 29589746 TI - Risk of Silver Transfer from Soil to the Food Chain Is Low after Long-Term (20 Years) Field Applications of Sewage Sludge. AB - The increasingly widespread usage of silver (Ag) nanoparticles has raised concerns regarding their environmental risk. The behavior of Ag and its transfer risk to the food chain were investigated using a long-term field experiment that commenced in 1942 in which Ag-containing sewage sludge was repeatedly applied to the soil (25 applications during 20 years). The speciation of the Ag in both the sludge and the soils retrieved from the long-term experimental archive was examined using synchrotron-based X-ray absorption spectroscopy, and extractable Ag concentrations from soils were determined using 0.01 M Ca(NO3)2 and 0.005 M DTPA. The total Ag in the sludge during the time period of 1942-1961 ranged from 155 to 463 mg kg-1. These values are 1-2 orders of magnitude higher than those in currently produced sludge (ca. 0.5-20 mg kg-1). Long-term repeated applications of these sludges resulted in an increase of Ag in soils from 1.9 mg kg-1 in the control to up to 51 mg kg-1. The majority (>80%) of the Ag in both the sludge and the sludge-treated soils was present as insoluble Ag2S, thereby markedly reducing the bioavailability of this Ag. Concentrations of Ag in the archived crop samples were generally <0.70 mg kg-1 in edible tissues, much less than those in diets that may cause an adverse effects in animals and humans (>100 mg kg-1). These data indicate that the transfer of Ag (derived from both traditional Ag industry and current nano Ag industry) to the terrestrial food chain is limited.

AB - Advances in the development of fluorescent carbon dots (CDs) for detecting nitro explosives have attracted great interest. However, developing long-wavelength luminescence CDs for highly selective determination of 2,4,6-trinitrophenol (TNP) and getting insight into the detection mechanism remain further to be investigated. Here, excitation-independent yellow-green emission CDs with good photostability and low biotoxicity were introduced for detecting TNP selectively. Then, two types of electron transfer (ET) processes including hydrogen-bond interaction-assisted ET and proton transfer-assisted ET are suggested to be responsible for their photophysical behavior. Finally, the visual detection of TNP has been successfully developed by a CD-based indicator paper. The facile, highly sensitive, and selective detection for TNP in both of a solution and a solid phase makes CDs potentially useful in environmental sensor applications.

AB - Arf-GAP with Rho-GAP domain, ANK repeat and PH domain-containing protein 1 (ARAP1), Cbl-interacting protein of 85 kDa (CIN85), and casitas B-lineage lymphoma (Cbl) play important roles in epidermal growth factor receptor (EGFR) internalization and recycling. In previous studies, ARAP1 was found to interact with CIN85, and their interaction attenuated the ubiquitination of EGFR. However, the molecular mechanism was still unclear. In this study, we first biochemically and structurally characterized the interaction between ARAP1 and CIN85, and found that the CIN85 SH3B domain bound to the ARAP1 PXPXXRX (except P) XXR/H/K motif with high affinity and specificity. Based on this binding model, we further predicted other potential CIN85 binding partners and tested their interactions biochemically. Moreover, our swapping data and structure alignment analysis suggested that the beta2-beta3 loops of the CIN85 SH3 domains and the H87ARAP1/E132CIN85 interaction were critical for ARAP1 binding specificity. Finally, our competitive analytical gel-filtration chromatography and isothermal titration calorimetry (ITC) results showed that ARAP1 could compete with Cbl for CIN85 binding, which provides a biochemical basis for the regulatory roles of ARAP1 in the CIN85-mediated EGFR internalizing process.

PMID- 29589750 TI - Argonaute Facilitates the Lateral Diffusion of the Guide along Its Target and Prevents the Guide from Being Pushed Away by the Ribosome. AB - Argonaute (AGO) proteins play central roles in nucleic acid-guided interference that regulates gene expression and defend against foreign genetic elements in all life. Although much progress has been made with respect to the function of argonaute proteins in target recognition and cleavage, the detailed mechanism of their biological functions is not fully understood. Here, using atomic force microscopy-based single-molecule force spectroscopy, we studied target-guide dissociation in the absence or presence of Thermus thermophilus AGO (TtAGO). Our results indicated that AGO changed the fundamental properties of target-guide interaction. Dissociation of the target from the guide is easier in the lateral direction of the nucleic acid in the presence of AGO protein but harder in the longitudinal direction. Our results support the idea that one-dimensional diffusion of the RNA-induced silencing complex (RISC) along the target strand is more efficient than three-dimensional diffusion and explain the priority of RISC binding over the ribosome complex during translation elongation. PMID- 29589751 TI - Total Synthesis of Biselyngbyolide B and Its C21-C22 Z-Isomer. AB - Investigations toward the synthesis of the 18-membered macrolactone biselyngbyolide B (2) from a C1-C13 and a C14-C23 fragment are described. As a key reaction in the synthesis of the C1-C13 fragment, we used an asymmetric propargylation of chiral vinylketene silyl N, O-acetal 12. Access to a C14-C23 fragment featuring a skipped diene and a sensitive allyl alcohol function was initially attempted via reductive fragmentation of a pyran template. However, this ring opening on iodide 32 with t-BuLi led to dienynol 33 with a 21 Z double bond. With a silyl protecting group at 3-OH and by implementing an intramolecular Stille coupling for macrolactonization, the 21 Z-isomer of biselyngbyolide B (47) was obtained. For preparation of a C14-C23 fragment with the 21 E-configuration, a cross-coupling of vinylstannane 48 with 4-bromocrotonate (49) set the configuration of the two double bonds. Biselyngbyolide B (2) was then accessed by an intramolecular Heck coupling. In preliminary biological cytotoxicity assays, 2 turned out to be active, whereas the 21 Z-isomer 47 was much less active. The 3 OMEM analogue 40 was devoid of activity. These results support the notion that the side chain with the correct configuration is relevant for binding to the Ca2+ ATPase and the biological activity. PMID- 29589752 TI - Computational Study of Microhydration in Sulfonated Diels-Alder Poly(phenylene) Polymers. AB - The nature of microhydration in sulfonated Diels-Alder poly(phenylene) (SDAPP) polymer membranes is explored using ab initio and density functional theory (DFT) electronic structure calculations. The impact of the aromatic poly(phenylene) structure, including cooperative effects between multiple spatially adjacent sulfonic groups, on the hydration environment is addressed using a series of DFT B3LYP/6-311**-optimized structures for different SDAPP. nH2O clusters. In addition, larger SDAPP polymer fragments, along with selected hydrophilic domain structures extracted from molecular dynamic (MD) simulations, are also evaluated using ONIOM HF/PM6 semiempirical calculations. The SDAPP clusters reveal that spontaneous proton dissociation occurs at low levels of hydration to form sulfonic-acid-associated H3O+ contact ion pairs (CIPs), which then evolve into solvated CIPs at higher hydration levels. For multiple sulfonic acid groups located on the poly(phenylene) side chains, the hydration energies are a function of the relative acid location and backbone configuration. Variations in the phenylene backbone torsional angles allow remote sulfonic acids to adopt an optimal separation to produce an extended hydrogen bonded network of waters between the SDAPP acids groups. These calculations provide a baseline to help describe the proton transport and hydration behavior of SDAPP membranes.

AB - In the hydrothermal synthesis of highly ordered mesoporous silica material SBA 15, strong acid is typically required to catalyze the hydrolysis and condensation of silica species. Meanwhile, under strongly acidic conditions, the transition metal ions, e.g., iron ions, are difficult to incorporate into SBA-15 because of the facile dissociation of Fe-O-Si bonds. Here, we demonstrate an acid-free green synthetic strategy for the synthesis of highly ordered mesoporous SBA-15 and Fe SBA-15 with the assistance of hydroxyl free radicals that are generated by physical or chemical methods. The prepared materials exhibit a large specific surface area compared to the counterparts prepared by conventional method under acidic conditions. Moreover, Fe-SBA-15 shows high metal loading efficiency as over 50%. Density functional theory calculations suggest that the hydroxyl free radicals exhibit higher catalytic activity than H+ ions for the hydrolysis of tetraethyl orthosilicate. This radical-facilitated synthesis approach overcomes the challenge to the direct synthesis of highly ordered SBA-15 and Fe-SBA-15 without adding any acid, providing a facile and environmentally friendly route for future large-scale production of ordered mesoporous materials. PMID- 29589754 TI - Phenothiazine Radical Cation Excited States as Super-oxidants for Energy Demanding Reactions. AB - We demonstrate that the 10-phenyl-10 H-phenothiazine radical cation (PTZ+*) has a manifold of excited doublet states accessible using visible and near-infrared light that can serve as super-photooxidants with excited-state potentials is excess of +2.1 V vs SCE to power energy demanding oxidation reactions. Photoexcitation of PTZ+* in CH3CN with a 517 nm laser pulse populates a Dn electronically excited doublet state that decays first to the unrelaxed lowest electronic excited state, D1' (tau < 0.3 ps), followed by relaxation to D1 (tau = 10.9 +/- 0.4 ps), which finally decays to D0 (tau = 32.3 +/- 0.8 ps). D1' can also be populated directly using a lower energy 900 nm laser pulse, which results in a longer D1'->D1 relaxation time (tau = 19 +/- 2 ps). To probe the oxidative power of PTZ+* photoexcited doublet states, PTZ+* was covalently linked to each of three hole acceptors, perylene (Per), 9,10-diphenylanthracene (DPA), and 10 phenyl-9-anthracenecarbonitrile (ACN), which have oxidation potentials of 1.04, 1.27, and 1.6 V vs SCE, respectively. In all three cases, photoexcitation wavelength dependent ultrafast hole transfer occurs from Dn, D1', or D1 of PTZ+* to Per, DPA, and ACN. The ability to take advantage of the additional oxidative power provided by the upper excited doublet states of PTZ+* will enable applications using this chromophore as a super-oxidant for energy-demanding reactions. PMID- 29589755 TI - Ultrahigh Frequency Nanomechanical Piezoresistive Amplifiers for Direct Channel Selective Receiver Front-Ends. AB - Channel-selective filtering and amplification in ultrahigh frequency (UHF) receiver front-ends are crucial for realization of cognitive radio systems and the future of wireless communication. In the past decade, there have been significant advances in the performance of microscale electromechanical resonant devices. However, such devices have not yet been able to meet the requirements for direct channel selection at RF. They also occupy a relatively large area on the chip making implementation of large arrays to cover several frequency bands challenging. On the other hand, electromechanical piezoresistive resonant devices are active devices that have recently shown the possibility of simultaneous signal amplification and channel-select filtering at lower frequencies. It has been theoretically predicted that if scaled down into the nanoscale, they can operate in the UHF range with a very low power consumption. Here, for the first time nanomechanical piezoresistive amplifiers with active element dimensions as small as 50 nm * 200 nm are demonstrated. With a device area of less than 1.5 MUm2 a piezoresistive amplifier operating at 730 MHz shows effective quality factor ( Q) of 89,000 for a 50Omega load and gains as high as 10 dB and Q of 330,000 for a 250Omega load while consuming 189 MUW of power. On the basis of the measurement results, it is shown that for piezoresistor dimensions of 30 nm * 100 nm it is possible to get a similar performance at 2.4 GHz with device footprint of less than 0.2 MUm2.

AB - Endotoxicity originating from a dangerous debris (i.e., lipopolysaccharide, LPS) of Gram-negative bacteria is a challenging clinical problem, but no drugs or therapeutic strategies that can successfully address this issue have been identified yet. In this study, we report a subnanometer gold cluster that can efficiently block endotoxin activity to protect against sepsis. The endotoxin blocker consists of a gold nanocluster that serves as a flakelike substrate and a coating of short alkyl motifs that act as an adhesive to dock with LPS by compacting the intramolecular hydrocarbon chain-chain distance ( d-spacing) of lipid A, an endotoxicity active site that can cause overwhelming cytokine induction resulting in sepsis progression. Direct evidence showed the d-spacing values of lipid A to be decreased from 4.19 A to either 3.85 or 3.54 A, indicating more dense packing densities in the presence of subnanometer gold clusters. In terms of biological relevance, the concentrations of key pro inflammatory NF-kappaB-dependent cytokines, including plasma TNF-alpha, IL-6, and IL-1beta, and CXC chemokines, in LPS-challenged mice showed a noticeable decrease. More importantly, we demonstrated that the treatment of antiendotoxin gold nanoclusters significantly prolonged the survival time in LPS-induced septic mice. The ultrasmall gold nanoclusters could target lipid A of LPS to deactivate endotoxicity by compacting its packing density, which might constitute a potential therapeutic strategy for the early prevention of sepsis caused by Gram negative bacterial infection.

AB - We report the detailed computational study of several perchlorinated cyclohexasilane (Si6Cl12)-based inverse sandwich compounds. It was found that regardless of the donor ligand size and charge, for example, Cl- and CN- anions or neutral HCN and NCPh nitriles, their coordination to the puckered Si6Cl12 ring results in its flattening. The NBO and CDA studies of the complexes showed that coordination occurs due to hybridization of low-lying antibonding sigma*(Si-Cl) and sigma*(Si-Si) unoccupied molecular orbitals (UMOs) of Si6Cl12 and occupied molecular orbitals (OMOs) of donor molecules (predominantly lone-pair-related), resulting in donor-to-ring charge transfer accompanied by complex stabilization and ring flattening. It is known that the Si6 ring distortion results from vibronic coupling of OMO and UMO pairs (pseudo-Jahn-Teller effect, PJT). Consequently, the Si6 ring flattening most probably occurs due to suppression of the PJT effect in all of the studied compounds. In this paper, the stabilization energy E(2) associated with donor-acceptor charge transfer (delocalization) was estimated using NBO analysis for [Si6Cl12.2Cl]2-, [Si6Cl12.2(NC)]2-, Si6Cl12.2(NCH), and Si6Cl12.2(NCPh). It was found that the polarizability of the donor might significantly affect the stabilization energy value (Cl- > CN- > HCN). For the neutral complexes, the E(2) value is correlated with the charge on the nitrogen atoms. All of these factors, that is, specific donor E(2) value, charge transfer, complex MO energy diagrams, and so on, should be taken into account when choosing the ligands suitable for forming Si-based 1D compounds and other nanoscale materials.

AB - Monolayer transition metal dichalcogenides (TMDCs) have recently emerged as a host material for localized optically active quantum emitters that generate single photons. (1-5) Here, we investigate fully localized excitons and trions from such TMDC quantum emitters embedded in a van der Waals heterostructure. We use direct electrostatic doping through the vertical heterostructure device assembly to generate quantum confined trions. Distinct spectral jumps as a function of applied voltage bias, and excitation power-dependent charging, demonstrate the observation of the two different excitonic complexes. We also observe a reduction of the intervalley electron-hole exchange interaction in the confined trion due to the addition of an extra electron, which is manifested by a decrease in its fine structure splitting. We further confirm this decrease of exchange interaction for the case of the charged states by a comparative study of the circular polarization resolved photoluminescence from individual excitonic states. The valley polarization selection rules inherited by the localized trions will provide a pathway toward realizing a localized spin-valley-photon interface.

PMID- 29589761 TI - Drop Capturing Based on Patterned Substrate in Space. AB - In this work, we introduced a method for capturing aqueous drop based on a patterned substrate in space. Through the manipulation test of a colloidal drop, it could be verified that this patterned substrate had excellent control ability for aqueous drop in microgravity condition. The confinement mechanism of this substrate was clarified, which showed that drops with different volume could be pinned and attracted at a given area on the substrate. The confinement capability was related to the gravity effect, and the patterned substrate could confine aqueous drops with larger volume under microgravity than in normal gravity. With advantages of simple operation and strong capability to control large drops, this technique exhibited the wide application prospect in the fields of fluid management, biosensing, and pharmacy in microgravity condition in the future.

AB - Single-molecule force spectroscopy techniques are powerful tools for investigating the mechanical unfolding of biomolecules. However, they are limited in throughput and require dedicated instrumentation. Here, we report a force generating particle that can unfold target molecules on-demand. The particle consists of a plasmonic nanorod core encapsulated with a thermoresponsive polymer shell. Optical heating of the nanorod leads to rapid collapse of the polymer, thus transducing light into mechanical work to unfold target molecules. The illumination tunes the duration and degree of particle collapse, thus controlling the lifetime and magnitude of applied forces. Single-molecule fluorescence imaging showed reproducible mechanical unfolding of DNA hairpins. We also demonstrate the triggering of 50 different particles in <1 min, exceeding the speed of conventional atomic force microscopy. The polymer force clamp represents a facile and bottom-up approach to force manipulation.

AB - 1H nuclear magnetic resonance (NMR)-based metabolomics can rapidly detect metabolic shift under various stimulus; thus, it facilitated the dissection of the therapeutic mechanisms of compounds. (-)-5-Hydroxy-equol is an isoflavone metabolite that be obtained by microbial biotransformation. In the current work, the effect of (-)-5-hydroxy-equol on hepatocellular carcinoma (HCC) cells and its mechanism have been explored based on 1H NMR-based metabolomics approach. Our results revealed that (-)-5-hydroxy-equol can significantly inhibit the proliferation, migration, and invasion of SMMC-7721 cells and inhibit the proliferation of HepG2 cells. Metabolomics revealed that 17 differential metabolites involving in amino acid metabolism and energy metabolism were significantly changed inside and outside of the cells after treatment of (-)-5 hydroxy-equol. Specifically, (-)-5-hydroxy-equol at a concentration of 30 MUM significantly decreased the concentrations of pyruvate, glutamate, and glucose. Because glycometabolism is a crucial feature of cancer-specific metabolism, we further verified enzymes and proteins that are closely relevant to glycometabolism. Our results indicated that (-)-5-hydroxy-equol-modulated glycolysis in HCC through the inhibition of activities of hexokinase, phosphofructokinase, and pyruvate kinase, and the expression of pyruvate kinase M2. This study revealed that metabolomic analysis integrating with further verifications at the biochemical level can facilitate understanding the anti-HCC mechanisms of (-)-5-hydroxy-equol.

AB - Photosystem II uses the energy of absorbed light to split water molecules, generating molecular oxygen, electrons, and protons. The four protons generated during each reaction cycle are released to the lumen via mechanisms that are poorly understood. Given the complexity of photosystem II, which consists of multiple protein subunits and cofactor molecules and hosts numerous waters, a fundamental issue is finding transient networks of hydrogen bonds that bridge potential proton donor and acceptor groups. Here, we address this issue by performing all-atom molecular dynamics simulations of wild-type and mutant photosystem II monomers, which we analyze using a new protocol designed to facilitate efficient analysis of hydrogen-bond networks. Our computations reveal that local protein/water hydrogen-bond networks can assemble transiently in photosystem II such that the reaction center connects to the lumen. The dynamics of the hydrogen-bond networks couple to the protonation state of specific carboxylate groups and are altered in a mutant with defective proton transfer. Simulations on photosystem II without its extrinsic PsbO subunit provide a molecular interpretation of the elusive functional role of this subunit. PMID- 29589764 TI - The alleviating effects of sesame oil on diazinon-induced toxicity in male wistar rats. AB - Pesticides are introduced into the environment in a variety of ways and constitute a wide group of environmental pollutants. To evaluate the attenuating effects of sesame oil on the toxicity of diazinon (DZN), male Wistar rats were exposed to DZN and/or sesame oil by gavage at different dosages for 8 weeks. DZN in a concentration of 30 mg/kg caused an increase in the number of white blood cell (WBCs), and the combination of DZN and sesame oil raised the number of platelets; the number of red blood cells, however, did not change. In addition, DZN caused a drastic decrease in the sperm count in a dose-dependent manner and in a concentration of 50 mg/kg, the sperm count decreased by more than 50%, but the combination of sesame oil in a dose of 4 ml/kg with DZN reversed the effect of this pesticide. The evidence presented here suggests that in addition to antioxidants, such as olive oil, intermittent exposure with sufficient intervals can decrease the toxicity of pesticides.

PMID- 29589766 TI - Memory enhancing effect of Nigella Sativa hydro-alcoholic extract on lipopolysaccharide-induced memory impairment in rats. AB - In this study, the effects of Nigella Sativa (NS) hydro-alcoholic extract on lipopolysaccharide (LPS)-induced learning and memory impairments, hippocampal cytokine levels, and brain tissues oxidative damage were investigated in rats. The rats were grouped and treated: (1) control (saline), (2) LPS (1 mg/kg i.p.), and (3-5) 100, 200, or 400 mg/kg NS hydro-alcoholic extract 30 min before LPS injection. The treatment was started since 6 days before the behavioral experiments and continued during the behavioral tests (LPS injection 2 h before each behavioral experiment). Finally, the brains were removed for biochemical assessments. In Morris water maze (MWM) test, LPS increased the escape latency and traveled path compared to control group, whereas all doses of NS hydro alcoholic extract decreased them compared to LPS group. In passive avoidance (PA) test, the latency to enter the dark compartment in LPS group was shorter than control group while in all treated groups it was longer than LPS group. LPS increased tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), malondialdehyde (MDA), and nitric oxide (NO) metabolites, and decreased thiol content, superoxide dismutase (SOD), and catalase (CAT) in the hippocampal tissues compared to control group while NS hydro-alcoholic extract decreased MDA and NO metabolites and increased thiol content, SOD, and CAT compared to LPS group. Findings of the current study indicated that the hydro-alcoholic extract of NS improved the LPS-induced learning and memory impairments induced by LPS in rats by improving hippocampal cytokine levels and brain tissues oxidative damage. PMID- 29589767 TI - Magnetic-resonance-imaging-based three-dimensional muscle reconstruction of hip abductor muscle volume in a person with a transfemoral bone-anchored prosthesis: A feasibility study. AB - BACKGROUND: Persons with transfemoral amputation typically have severe muscle atrophy of the residual limb. The effect of bone-anchored prosthesis use on existing muscle atrophy is unknown. A potentially feasible method to evaluate this is magnetic resonance imaging (MRI)-based three-dimensional (3D) muscle reconstruction. We aimed to (1) examine the feasibility of MRI-based 3D muscle reconstruction technique in a person with a cobalt-chrome-molybdenum transfemoral bone-anchored prosthesis; and (2) describe the change of hip abductor muscle volume over time. METHODS: In this single case, 1-year follow-up study we reconstructed the 3D hip abductor muscle volumes semiautomatically from MRI scans at baseline, 6- and 12-month follow-up. The number of adverse events, difficulties in data analysis, time investment and participants' burden determined the level of feasibility. RESULTS: We included a man (70 years) with a transfemoral amputation who received a bone-anchored prosthesis after 52 years of socket prosthesis use. No adverse events occurred. The accuracy of the 3D reconstruction was potentially reduced by severe adipose tissue interposition. Data analysis was time-intensive (115 h). Participants' burden was limited to 3-h time investment. Compared to baseline, the total hip abductor volume of both the residual limb (6 month: 5.5%; 12 month: 7.4%) and sound limb (6 month: 7.8%; 12 month: 5.5%) increased. CONCLUSION: The presented technique appears feasible to follow muscle volume changes over time in a person with a cobalt-chrome molybdenum transfemoral bone-anchored prosthesis in an experimental setting. Future research should focus on analysis of muscle tissue composition and the feasibility in bone-anchored prostheses of other alloys. PMID- 29589769 TI - Comparison of portable handheld versus fixed isokinetic dynamometers in measuring strength of the wrist and forearm. AB - PURPOSE: The purpose of this study was to test the concurrent validity of using hydraulic dynamometers in comparison to the gold standard isokinetic dynamometers in measuring wrist and forearm strength. MATERIALS AND METHODS: Healthy adults between the ages of 18-65 participated, including 24 participants, 8 men and 16 women. The examiner used a handheld dynamometer, forearm/wrist dynamometer, and an isokinetic dynamometer to measure force/torque production in forearm rotation and wrist flexion/extension using a standardized protocol of two handle types for each motion. Sequence of testing was randomized. The data were analyzed using Pearson correlation coefficients and paired t-tests. RESULTS: When matched for handle type, three of the four correlations between the strength measurements taken with the different dynamometers were moderate to high with Pearson product moment coefficients ranging from 0.72 to 0.96; the screwdriver handle demonstrated less than acceptable correlation (r = 0.45, 0.67 for wrist flexion and extension, respectively). There were significant differences in most of the force/torque values obtained by different handle types for wrist and forearm motions. DISCUSSION AND CONCLUSIONS: Overall, the dynamometers demonstrated acceptable correlations supporting concurrent validity for measuring forearm and wrist strength, except with the screwdriver handle. However, different tools, positions, and handle interfaces provided different absolute values, therefore the tools cannot be used interchangeably. It is recommended that repeated measurements to monitor patient progress are taken with the same tool and handle type. PMID- 29589768 TI - IOC Consensus Statement: Dietary Supplements and the High-Performance Athlete. AB - Nutrition usually makes a small but potentially valuable contribution to successful performance in elite athletes, and dietary supplements can make a minor contribution to this nutrition program. Nonetheless, supplement use is widespread at all levels of sport. Products described as supplements target different issues, including the management of micronutrient deficiencies, supply of convenient forms of energy and macronutrients, and provision of direct benefits to performance or indirect benefits such as supporting intense training regimens. The appropriate use of some supplements can offer benefits to the athlete, but others may be harmful to the athlete's health, performance, and/or livelihood and reputation if an anti-doping rule violation results. A complete nutritional assessment should be undertaken before decisions regarding supplement use are made. Supplements claiming to directly or indirectly enhance performance are typically the largest group of products marketed to athletes, but only a few (including caffeine, creatine, specific buffering agents and nitrate) have good evidence of benefits. However, responses are affected by the scenario of use and may vary widely between individuals because of factors that include genetics, the microbiome, and habitual diet. Supplements intended to enhance performance should be thoroughly trialed in training or simulated competition before implementation in competition. Inadvertent ingestion of substances prohibited under the anti doping codes that govern elite sport is a known risk of taking some supplements. Protection of the athlete's health and awareness of the potential for harm must be paramount, and expert professional opinion and assistance is strongly advised before embarking on supplement use. PMID- 29589770 TI - ROS and RNS signalling: adaptive redox switches through oxidative/nitrosative protein modifications. AB - Over the last decade, a dual character of cell response to oxidative stress, eustress versus distress, has become increasingly recognized. A growing body of evidence indicates that under physiological conditions, low concentrations of reactive oxygen and nitrogen species (RONS) maintained by the activity of endogenous antioxidant system (AOS) allow reversible oxidative/nitrosative modifications of key redox-sensitive residues in regulatory proteins. The reversibility of redox modifications such as Cys S-sulphenylation/S glutathionylation/S-nitrosylation/S-persulphidation and disulphide bond formation, or Tyr nitration, which occur through electrophilic attack of RONS to nucleophilic groups in amino acid residues provides redox switches in the activities of signalling proteins. Key requirement for the involvement of the redox modifications in RONS signalling including ROS-MAPK, ROS-PI3K/Akt, and RNS TNF-alpha/NF-kB signalling is their specificity provided by a residue microenvironment and reaction kinetics. Glutathione, glutathione peroxidases, peroxiredoxins, thioredoxin, glutathione reductases, and glutaredoxins modulate RONS level and cell signalling, while some of the modulators (glutathione, glutathione peroxidases and peroxiredoxins) are themselves targets for redox modifications. Additionally, gene expression, activities of transcription factors, and epigenetic pathways are also under redox regulation. The present review focuses on RONS sources (NADPH-oxidases, mitochondrial electron transportation chain (ETC), nitric oxide synthase (NOS), etc.), and their cross talks, which influence reversible redox modifications of proteins as physiological phenomenon attained by living cells during the evolution to control cell signalling in the oxygen-enriched environment. We discussed recent advances in investigation of mechanisms of protein redox modifications and adaptive redox switches such as MAPK/PI3K/PTEN, Nrf2/Keap1, and NF-kappaB/IkappaB, powerful regulators of numerous physiological processes, also implicated in various diseases. PMID- 29589771 TI - Effect of oral exposure to acrylamide on biochemical and hematologic parameters in Wistar rats. AB - The toxic effects of ACR monomer include carcinogenesis, cellular genotoxic, and neurotoxicity. In this study, we examined the effect of acrylamide on biochemical and hematologic parameters in Wistar rats and explored the renal and hepatic function of these animals through a complementary anatomopathologic study. For it, thirty female Wistar rats aged 4 weeks and weighing 100 +/- 10 g were housed six animals per cage and divided as follows: two groups were exposed for 2 months to drinking water containing 5 mg (Group 2) or 10 mg acrylamide (Group 3); one group of 12 rats received the median lethal dose of acrylamide by gavage (Group 4); and the control group (Group 1) received pure water. The results clearly showed that acrylamide affects various biochemical parameters, such as creatinine, urea, and serum globulin levels and the lipid balance, which are directly related to renal and hepatic dysfunction and disruption of the hematologic system. In addition, the data revealed changes in the complete blood count (CBC); significant increases in the number of leukocytes (9.95 +/- 1.44 and 10.44 +/- 1.21) and lymphocytes (6.11 +/- 0.48 and 6.33 +/- 0.76) in Groups 3 and 4, respectively; and decreases in total protein (88.95 +/- 6.36), albumin (37.65 +/- 1.65) and alpha-1 globulin levels (24.84 +/- 2.10) in Group 3. The anatomopathologic study confirmed liver damage in the animals administered an acrylamide containing diet compared with those in the control group. The present study confirmed the effects of acrylamide on different hematologic, biochemical and immunologic parameters, with a specific focus on the liver and kidney, and on the induction of neurotoxic disorders. The results showed that oral exposure to acrylamide via drinking water or gavage induces kidney damage, hepatocellular insufficiency and chronic liver disease, resulting in primary immunodeficiency and activation of the immune system following the possible expression of certain immunoreaction genes. PMID- 29589772 TI - Alda-1, an ALDH2 activator, protects against hepatic ischemia/reperfusion injury in rats via inhibition of oxidative stress. AB - Previous studies have proved that activation of aldehyde dehydrogenase two (ALDH2) can attenuate oxidative stress through clearance of cytotoxic aldehydes, and can protect against cardiac, cerebral, and lung ischemia/reperfusion (I/R) injuries. In this study, we investigated the effects of the ALDH2 activator Alda 1 on hepatic I/R injury. Partial warm ischemia was performed in the left and middle hepatic lobes of Sprague-Dawley rats for 1 h, followed by 6 h of reperfusion. Rats received either Alda-1 or vehicle by intravenous injection 30 min before ischemia. Blood and tissue samples of the rats were collected after 6 h reperfusion. Histological injury, proinflammatory cytokines, reactive oxygen species (ROS), cellular apoptosis, ALDH2 expression and activity, 4-hydroxy-trans 2-nonenal (4-HNE) and malondialdehyde (MDA) were measured. BRL-3A hepatocytes were subjected to hypoxia/reoxygenation (H/R). Cell viability, ROS, and mitochondrial membrane potential were determined. Pretreatment with Alda-1 significantly alleviated I/R-induced elevations of alanine aminotransferase and aspartate amino transferase, and significantly blunted the pathological injury of the liver. Moreover, Alda-1 significantly inhibited ROS and proinflammatory cytokines production, 4-HNE and MDA accumulation, and apoptosis. Increased ALDH2 activity was found after Alda-1 administration. No significant changes in ALDH2 expression were observed after I/R. ROS was also higher in H/R cells than in control cells, which was aggravated upon treatment with 4-HNE, and reduced by Alda-1 treatment. Cell viability and mitochondrial membrane potential were inhibited in H/R cells, which was attenuated upon Alda-1 treatment. Activation of ALDH2 by Alda-1 attenuates hepatic I/R injury via clearance of cytotoxic aldehydes. PMID- 29589773 TI - Readiness to change for interprofessional collaboration in healthcare: Development and validation of a theory-based instrument. AB - This paper presents a study that aimed to develop and validate a theory-based instrument for the assessment of readiness to change for interprofessional collaboration in healthcare (IPC-TTM). The instrument was developed in the Persian language and tested in the Iranian context. Healthcare professionals from medical and nursing professions participated in the assessment of validity and reliability of the instrument. We conducted this psychometric study in two phases: First, the questionnaire was developed based on the transtheoretical model (TTM) through literature review and expert panel. Then, in the validation phase, we held three modified Delphi rounds to assess the content and face validity of the questionnaire. We used confirmatory factor analysis (CFA) to evaluate the fit of the questionnaire as applied to modified TTM. Reliability of the final instrument was tested by assessing the test-retest reliability of instrument items with Kappa coefficient. We also calculated the intraclass correlation coefficient (ICC) and Cronbach's alpha to assess the test-retest reliability and internal consistency of the instrument sub-scales. The initial item pool consisted of 30 items and three sub-scales (Attitude, Intention, and Action). The content validity of the questionnaire was confirmed with 17 items. Based on the CFA results two additional items were deleted to increase the fit of the model. The final instrument was confirmed with 15 items and three sub-scales. Reliability assessment on the 15-item instrument showed an acceptable test-retest reliability of the instrument items. ICC values for the Attitude, Intention, and Action sub-scales of the instrument were calculated as 0.82, 0.73, and 0.71, respectively. Moreover, Cronbach's alpha for the Attitude, Intention, and Action sub-scales were 0.85, 0.73, and 0.77, respectively. This study offers a new theory-based instrument to measure readiness to change for interprofessional collaboration in healthcare in the Iranian context. The questionnaire can be used for 'needs assessment' in developing tailored educational interventions and self assessments in interprofessional education studies. PMID- 29589774 TI - Solution space: Monitoring the dynamics of motor rehabilitation. AB - This article presents and discusses a perspective on the concept of "solution space" in physiotherapy. The model is illustrated with a subjective assessment of the way movements are performed and an objective quantification of the dynamics of the recovery process for a patient with a knee injury. Based on insights from the domain of human motor control, solution space is a key concept in our recovery model that explains the emergence of a variety of adaptive changes that may occur in the movement system recovering from an injury. The three dimensions that span the solution space are: (1) information and control processes; (2) time; and (3) degrees of freedom. Each dimension is discussed within the context of feasible physiotherapeutic assessments to identify and facilitate desirable behavioral patterns or bypass emerging but undesirable behavioral patterns that could impede both short- and long-term recovery. Central to this article is our view on the relationship between the recovery process and the three dimensions of the solution space, which determines the model's usefulness as a motor rehabilitation monitoring tool. PMID- 29589775 TI - Role of CYP2C19 genotype testing in clinical use of clopidogrel: is it really useful? AB - INTRODUCTION: P2Y12 inhibitors, including clopidogrel have become an integral part of treatment for patients receiving coronary stent placement as a result of stable coronary artery disease or acute coronary syndromes (ACS) and also for medically managed ACS patients. Areas covered: Clopidogrel efficacy can be significantly modified by polymorphism of CYP2C19 genotype (more than 25 allelic variants) involved in its metabolism that can adversely affect its anti-platelet activity. As a result, a substantial number of patients (20-30%) with ACS show an inadequate response to clopidogrel despite a standardized dosing regimen. Experts commentary: Currently, there is conflicting evidence in regards to the use of CYP2C19 genotyping to identify poor responders to clopidogrel in clinical practice. ACC/AHA guidelines do not recommend routine use of CYP2C19 in clinical practice, whereas Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines recommend its use to identify poor/intermediate metabolizers of Clopidogrel and suggest alternative P2Y12 inhibitors among ACS patients undergoing percutaneous coronary intervention. This review article will look at the literature evidence for the use of CYP2C19 genotyping in clinical practice. PMID- 29589776 TI - Inter-rater reliability of DartfishTM movement analysis software for measuring maximum flexion and extension at the hip and knee in older adults with osteoporosis and osteopenia. AB - Various methods are used to measure hip and knee joint motion angles; however, their use is often limited by cost or inability to measure dynamic movements. The assessment of movement patterns is clinically useful in individuals with osteoporosis (OP) and osteopenia (OPe) through its potential to optimize fracture risk assessment. This study evaluates the inter-rater reliability of using DartfishTM 2-D Motion Analysis Software to measure maximum flexion and extension angles at the hip and knee in individuals with OP or OPe while performing five tasks of the Safe Functional Motion test. Twelve participants were videotaped performing the pour, footwear, newspaper, sweep, and sit-to-floor tasks. Five raters used DartfishTM to analyze maximum flexion and extension angles at the hip and knee, and an intra-class correlation coefficients (ICC) and SEM were calculated for each measurement. In all five tasks, ICC and SEM values ranged from 0.23 to 0.95, and 1.75 to 11.54 degrees, respectively, with maximum knee flexion angles generally having higher ICC, and lower SEM point estimates. The results indicate that DartfishTM measurements of maximum knee flexion angles in uniplanar tasks demonstrate a moderate to excellent degree of inter-rater reliability, while measurements at the hip joint should be used with caution. Given that the results of this study display moderate to excellent reliability, they lay the groundwork for future research aimed at determining the validity of these measurements. Such research would help to further develop the base of evidence surrounding the usefulness of DartfishTM Motion Analysis in fracture risk analysis among individuals with OP. PMID- 29589777 TI - Mirror therapy and treadmill training for a patient with chronic stroke: A case report. AB - INTRODUCTION: A large proportion of patients with chronic stroke have permanent lower limb functional disability leading to reduced levels of independent mobility. Individually, both mirror therapy and treadmill training have been shown to improve aspects of lower limb functioning in patients with stroke. This case report examined whether a new combination of both interventions would lead to improvements in lower limb functional disability for a patient with chronic stroke. CASE DESCRIPTION: The participant was a 50-year-old female who had a left middle cerebral artery infarction (47 months' post stroke). Due to hemiparesis, she had lower limb motor impairment and gait deficits. INTERVENTION: The participant engaged in a combination of mirror therapy and treadmill training for 30 minutes per day, 3 days per week, for 4 weeks. OUTCOMES: Modified Ashworth Scale, Fugl-Meyer Assessment-Lower Extremity and the 10 m Walk Test demonstrated clinically meaningful change. The 6 Minute Walk Test did not demonstrate meaningful change. DISCUSSION: The positive outcomes from this new combination therapy for this participant are encouraging given the relatively small dose of training and indicate the potential benefit of mirror therapy as an adjunct to treadmill training for enhancing lower limb muscle tone, motor function and walking velocity in patients with chronic stroke. PMID- 29589778 TI - Physiotherapy management of patients with chronic pelvic pain (CPP): A systematic review. AB - INTRODUCTION: Chronic pelvic pain (CPP) is a common pain condition. However, treatment remains challenging. Musculoskeletal findings are frequent; therefore physiotherapy might be helpful. The purpose of this review was to evaluate the current evidence on physiotherapy in patients with CPP (PROSPERO registration number CRD42016037516). METHODS: Six databases were searched and additional hand searches were performed. Two reviewers independently conducted the database search and selected studies using a two-step approach. The methodological quality was assessed applying the Critical Review Form - Quantitative Studies. RESULTS: A total of eight studies were included. Trigger point therapy was examined in four studies; two of which were randomized controlled trials. All studies indicate a significant change in pain measurement. The other four studies evaluated the effect of biofeedback, Thiele massage, Mensendieck somatocognitive therapy and aerobic exercises, whereas the last two were tested in controlled trials. All studies showed significant improvements in pain assessment. CONCLUSIONS: The evidence currently available is sparse with methodological flaws, making it difficult to recommend a specific physiotherapy option. There is an urgent need for high-quality randomized controlled trials to identify the most effective physiotherapy management strategy for patients with CPP. PMID- 29589779 TI - Telomere length is independently associated with age, oxidative biomarkers, and sport training in skeletal muscle of healthy adult males. AB - In skeletal muscle, which mainly contains postmitotic myonuclei, it has been suggested that telomere length remains roughly constant throughout adult life, or shortens in response to physiopathological conditions in muscle diseases or in the elderly. However, telomere length results from both the replicative history of a specific tissue and the exposure to environmental, DNA damage-related factors, therefore the predictive biological significance of telomere measures should combine the analysis of the various interactive factors. In the present study, we analysed any relationship between telomere length [mean and minimum terminal restriction fragment (TRF) length] chronological age, oxidative damage (4-HNE, protein carbonyls), catalase activity, and heat shock proteins expression (alphaB-crystallin, Hsp27, Hsp90) in semitendinous muscle biopsies of 26 healthy adult males between 20 and 50 years of age, also exploring the influence of regular exercise participation. The multiple linear regression analysis identified age, 4-HNE, catalase, and training status as significant independent variables associated with telomere length and jointly accounting for ~30-36% of interindividual variation in mean and/or minimum TRF length. No association has been identified between telomere length and protein carbonyl, alphaB-crystallin, Hsp27, and Hsp90, as well as between age and the variables related to stress response. Our results showed that skeletal muscle from healthy adults displays an age-dependent telomere attrition and that oxidised environment plays an age independent contribution, partially influenced by exercise training. PMID- 29589780 TI - What are private sector physiotherapists' perceptions regarding interprofessional and intraprofessional work for managing low back pain? AB - In the last decades, interactions between health professionals have mostly been discussed in the context of interprofessional teamwork where professionals work closely together and share a team identity. Comparatively, little work has been done to explore interactions that occur between professionals in contexts where traditionally formal structures have been less supporting the implementation of interprofessional teamwork, such as in the private healthcare sector. The objective of this study was to identify private sector physiotherapists' perceptions of interprofessional and intraprofessional work regarding interventions for adults with low back pain. This was a cross-sectional survey of 327 randomly-selected physiotherapists. Data were analysed using descriptive statistics. A majority of physiotherapists reported positive effects of interprofessional work for their clients, themselves and their workplaces. Proximity of physiotherapists with other professionals, clinical workloads, and client's financial situation were perceived as important factors influencing the implementation of interprofessional work. Low back pain is a highly prevalent and disabling condition. The results of this study indicate that integrating interprofessional work in the management of low back pain in the private sector is warranted. Furthermore, the implementation of interprofessional work is viewed by practicing physiotherapists as dependent upon certain client-, professional- and organizational-level factors. PMID- 29589781 TI - Physicians' perspectives of pharmacist-physician collaboration in the United Arab Emirates: Findings from an exploratory study. AB - Interprofessional collaborative care has been shown to improve patient outcomes. Physicians' views on collaboration with pharmacists give an insight into what contributes to a well-functioning team. Little is known about these views from low and middle-income countries and nothing from the United Arab Emirates (UAE). The purpose of this study is to investigate physicians' opinions on collaborative relationships with community pharmacists in the UAE. Semi-structured individual interviews and group discussions are conducted with a purposive sample of physicians. Thematic analysis based on the framework approach is used to generate themes. A total of 53 physicians participated. Three themes about collaboration emerged: perceived benefits of collaboration, facilitators of collaboration and perceived barriers to collaboration. Perceived benefits include reducing the burden on physicians, having the pharmacist as an extra safety check within the system, having the pharmacist assist patients to manage their medications: coping with side effects, reducing drug waste and costs, and attaining professional and health-system gains. Perceived facilitators included awareness and trust building, professional role definition, pharmacists' access to patient records and effective communication. Perceived barriers included patient and physician acceptance, logistic and financial issues and perceived pharmacist competence. This study has, for the first time, provided useful information to inform the future development of pharmacist-physician collaboration in the UAE and other countries with similar healthcare systems. PMID- 29589782 TI - Immediate preoperative outcomes of pain neuroscience education for patients undergoing total knee arthroplasty: A case series. AB - BACKGROUND: Standard preoperative education for total knee arthroplasty (TKA) has been shown to have no effect on postoperative outcomes. This may be because such education programs fail to educate patients about pain. Pain neuroscience education (PNE) focuses on teaching people more about pain from a neurobiological and neurophysiological perspective. DESIGN AND SETTING: Case Series. AIM: To determine the immediate effects, if any, of providing PNE before TKA surgery on patient self-report measures. PARTICIPANTS: Twelve patients (female = 10) prior to TKA for knee osteoarthritis (OA). INTERVENTION: Preoperative educational session by a physical therapist on the neuroscience of pain, accompanied by an evidence-based booklet. MAIN OUTCOME MEASURES: Comparison of pre- and post-PNE self-report measures on knee pain (NPRS), Pain Catastrophization Scale (PCS), fear of movement (TSK), and beliefs about TKA; as well as three physical performance measures - knee flexion active range of motion, 40 m self-paced walk, and pressure pain threshold (PPT). RESULTS: Immediately following the PNE, patients had statistically significant lower TSK scores, increased PPT, and improved beliefs about their upcoming surgery. There were no significant changes in knee pain, function, or flexion active range of motion. CONCLUSIONS: Results appear to suggest that immediately after PNE, patients scheduled for TKA had statistically significant changes in fear of movement, decreased sensitivity to pain and positive shifts in their beliefs about their future knee surgery. Larger trials with control/comparison groups are warranted to determine the true effects of preoperative PNE for patients about to undergo TKA.

AB - Spectrally resolved ultraviolet (UV) absorption cross-sections of gas-phase sodium chloride (NaCl), potassium hydroxide (KOH), and sodium hydroxide (NaOH) were measured, for the first time, in hot flue gases at different temperatures. Homogenous gas-phase NaCl, KCl (potassium chloride), NaOH, and KOH at temperatures 1200 K, 1400 K, 1600 K, and 1850 K were prepared in the post-flame zone of laminar flames by seeding nebulized droplets out of aqueous solution of corresponding alkali species. The amount of droplets seeded into the flame was kept constant, so the relative concentration of different alkali species can be derived. The broadband UV absorption cross-section of KCl vapor reported by Leffler et al. was adopted to derive the absorption cross-section curves of NaCl, NaOH, and KOH with the corresponding measured spectrally resolved absorbance spectra. No significant changes in the spectral structures in the absorption cross-sections were found as the temperature varied between 1200 K and 1850 K, except for NaOH at around 320 nm. The difference between the absorption spectral curves of alkali chlorides and hydroxides is significant at wavelengths above 300 nm, which thus can be used to distinguish and obtain the concentrations of alkali chlorides and hydroxides in the broadband UV absorption measurements. PMID- 29589784 TI - Short-Term Complications, Reoperations, and Radiographic Outcomes of a New Fixed Bearing Total Ankle Arthroplasty. AB - BACKGROUND: With the increasing use of total ankle arthroplasty (TAA), new implants with varied configurations are being developed every year. This study aimed to assess the early complications, reoperations, and radiographic and clinical outcomes of the Infinity TAA. To date, clinical results of this novel implant have not been published. METHODS: A retrospective analysis of 64 consecutive ankles that underwent a primary Infinity TAA from July 2014 to April 2016 was performed. Patients had an average follow-up of 24.5 (range, 18-39) months. Medical records were reviewed to determine the incidence of complications, reoperations, and revisions. Radiographic outcomes included preoperative and postoperative tibiotalar alignment, tibial implant positioning, the presence of periprosthetic radiolucency and cysts, and evidence of subsidence or loosening. Additionally, patient-reported outcomes were analyzed with the Foot and Ankle Outcome Score (FAOS). RESULTS: Survivorship of the implant was 95.3%. Fourteen ankles (21.8%) presented a total of 17 complications. A total of 12 reoperations were necessary in 11 ankles (17.1%). Revision surgery was indicated for 3 ankles (4.7%) as a result of subsidence of the implant. Tibiotalar coronal deformity was significantly improved after surgery ( P < .0001) and maintained during latest follow-up ( P = .81). Periprosthetic radiolucent lines were observed around the tibial component in 20 ankles (31%) and around the talar component in 2 ankles (3.1%). A tibial cyst was observed in 1 ankle (1.5%). Outcome scores were significantly improved for all FAOS components analyzed ( P < .0001), from 39.0 to 83.3 for pain, from 34.0 to 65.2 for symptoms, from 52.3 to 87.5 for activities of daily living, and from 15.7 to 64.2 for quality of life. CONCLUSION: Most complications observed in the study were minor and successfully treated with a single reoperation procedure or nonoperatively. Failures and radiographic abnormalities were most commonly related to the tibial implant. Further studies with longer follow-up are needed to evaluate the survivorship of the tibial implant in the long term. LEVEL OF EVIDENCE: Level IV, retrospective case series. PMID- 29589785 TI - Correlation of Clinical Evaluation and Radiographic Hindfoot Alignment in Stage II Adult-Acquired Flatfoot Deformity. AB - BACKGROUND: Previous work has demonstrated that the amount of radiographic hindfoot correction required at the time of adult-acquired flatfoot deformity (AAFD) operative treatment can be predicted by the amount of radiographic deformity present before surgery. Successful outcomes after reconstruction are closely correlated with hindfoot valgus correction. However, it is not clear if differences exist between clinical and radiographic assessment of hindfoot valgus. The purpose of this study was to evaluate the correlation between radiographic and clinical evaluation of hindfoot alignment in patients with stage II AAFD. METHODS: Twenty-nine patients (30 feet) with stage II AAFD, 17 men and 12 women, mean age of 51 (range, 20-71) years, were prospectively recruited. In a controlled and standardized fashion, bilateral weightbearing radiographic hindfoot alignment views were taken. Radiographic parameters were measured by 2 blinded and independent readers: hindfoot alignment angle (HAA) and hindfoot moment arm (HMA). Clinical photographs of hindfoot alignment were taken in 3 different vertical camera angulations (0, 20, and 40 degrees). Pictures were assessed by the same readers for standing tibiocalcaneal angle (STCA) and resting calcaneal stance position (RCSP). Intra- and interobserver reliability were assessed by Pearson/Spearman's and intraclass correlation coefficient (ICC), respectively. Relationship between clinical and radiographic hindfoot alignment was evaluated by a linear regression model. Comparison between the different angles (RCSP, STCA, and HAA) was performed using the Wilcoxon rank-sum test. P values of less than .05 were considered significant. RESULTS: We found overall almost perfect intraobserver (range, 0.91-0.99) and interobserver reliability (range, 0.74-0.98) for all measures. Mean value and confidence interval (CI) for RCSP and STCA were 10.8 degrees (CI, 10.1-11.5) and 12.6 degrees (CI, 11.7-13.4), respectively. The position of the camera did not influence readings of clinical alignment ( P > .05). The mean HMA was 18.7 mm (CI, 16.3-21.1 mm), and the mean HAA was 23.5 degrees (CI, 21.1-26.0). Clinical and radiographic hindfoot alignment were found to significantly correlate ( P < .05). However, the radiographic HAA demonstrated increased valgus compared to both clinical alignment measurements, with a mean difference of 12.8 degrees from the RCSP (CI, 11.0-14.5, P < .0001) and 11.0 degrees from the STCA (CI, 9.2-12.8, P < .0001). CONCLUSION: We found significant correlation between radiographic and clinical hindfoot alignment in patients with stage II AAFD. However, radiographic measurements of HAA demonstrated significantly more pronounced valgus alignment than the clinical evaluation. The results of our study suggest that clinical evaluation of hindfoot alignment in patients with AAFD potentially underestimates the bony valgus deformity. One should consider these findings when using clinical evaluation in the treatment algorithm of flatfoot patients. LEVEL OF EVIDENCE: Level II, prospective comparative study. PMID- 29589787 TI - Implementation of motor learning principles in physical therapy practice: Survey of physical therapists' perceptions and reported implementation. AB - INTRODUCTION: The field of motor learning (ML) plays a pivotal role in physical therapy (PT), and its implementation has been shown to improve intervention outcomes. The objective of this study was to assess physical therapists' ML related self-efficacy, self-reported implementation, and environmental workplace factors. An additional aim was to report the psychometric properties of a questionnaire that was developed to assess the above-mentioned constructs. METHODS: An observational, cross-sectional survey was completed by 289 physical therapists (average age: 38.7 (9.7), with 11.3 (9.7) years of experience and 74% female). Construct validity, internal consistency, and test-retest reliability were tested. The main outcome measures were the scores of the three scales of the questionnaire, referring to self-efficacy in ML, implementation of ML principles, and workplace environment features. RESULTS: The questionnaire had sound psychometric qualities. Respondents perceived ML as an integral part of PT. ML related self-efficacy and implementation of ML principles were moderate (2.95/5 (0.7) and 3.04/5(0.8), respectively). PT practice had a significant effect on ML related self-efficacy (p = 0.035) and implementation (p = 0.0031). Respondents who had undergone ML training in their graduate program reported higher ML related self-efficacy (p = 0.007). Respondents who had postgraduate training in ML reported significantly more extensive implementation (p = 0.024). Lack of knowledge and lack of time were perceived as the major barriers to implementation. CONCLUSIONS: Level of self-efficacy might be insufficient to support the systematic implementation of ML principles in practice. Addressing impeding individual- and organizational-level factors might facilitate ML self efficacy and implementation. Postgraduate education facilitates ML implementation. PMID- 29589788 TI - Emotional valence impacts lexical activation and inhibition differently in aging: an emotional Hayling task investigation. AB - BACKGROUND: Aging is characterized by cognitive changes such as a potential inhibition deficit. However, growing evidence shows that positive valence stimuli enhance performances in older adults to a greater degree than in younger adults. The aim of the present study was to investigate the effect of the emotional valence of words on lexical activation and inhibition in aging by using a new Emotional Hayling Task. METHODS: Thirty-eight younger adults (mean age = 20.11 years) and 38 older adults (mean age = 66.47 years) performed a computerized Emotional Hayling task. Participants had to choose the correct (initiation part) or incorrect (inhibition part) final words of highly predictable incomplete sentences. Final words had a negative or positive emotional valence and were paired for reaction time comparison with neutral words. RESULTS: Response times were faster in younger adults than in older adults in both the initiation and the inhibition parts. In addition, response times indicated that older adults initiated more slowly negative than neutral words while no differences emerged in inhibition. No differences were obtained between negative and neutral words in younger adults. Response times showed faster initiation and inhibition for positive than for neutral words in both age groups. CONCLUSION: These data are consistent with previous findings suggesting a disengagement from the processing of negative versus neutral words in older adults when compared with younger adults. A possible explanation is that activation of negative words in the mental lexicon is weaker in older than in younger adults. Conversely, the positive valence of words seems to enhance both activation and inhibition processes in both young and older adults. These findings suggest that positive stimuli can improve performance. PMID- 29589789 TI - Trial-by-trial modulations in the orienting of attention elicited by gaze and arrow cues. AB - Recent findings suggested that the orienting of attention towards gazed at locations (i.e., the gaze cueing effect) could result from the conflict emerging in incongruent trials between the spatial information conveyed by gaze direction and the target spatial position. In two experiments, we assessed this hypothesis by investigating whether this effect is influenced by the same trial-by-trial modulations that are reported in a spatial conflict task, i.e., the Simon task. In Experiment 1, we compared the trial-by-trial modulations emerging in the Simon task with those emerging in a gaze cueing task, while in Experiment 2, we compared gaze and arrows cues. Trial-by-trial modulations were evident in both tasks. In the Simon task, correspondence sequence affected both corresponding and noncorresponding responses, this resulting in a larger Simon effect when the preceding trial was corresponding and an absent effect when the preceding trial was noncorresponding. Differently, in the gaze cueing task, congruence sequence affected only congruent responses with faster responses when the preceding trial was congruent compared to when it was incongruent, resulting in a larger gaze cuing effect when the preceding trial was congruent. Same results were evident with nonpredictive arrow cues. These findings speak against a spatial conflict account. PMID- 29589790 TI - Object attraction effects during subject-verb agreement in Persian. AB - Subject-verb agreement provides insight into how grammatical and semantic features interact during sentence production, and prior studies have found attraction errors when an intervening local noun is grammatically part of the subject. Two major types of theories have emerged from these studies: control based and competition-based. The current study used an subject-object-verb language with optional subject-verb agreement, Persian, to test the competition based hypothesis that intervening object nouns may also cause attraction effects, even though objects are not part of the syntactic relationship between the subject and verb. Our results, which did not require speakers to make grammatical errors, show that objects can be attractors for agreement, but this effect appears to be dependent on the type of plural marker on the object. These results support competition-based theories of agreement production, in which agreement may be influenced by attractors that are outside the scope of the subject-verb relationship. PMID- 29589791 TI - Evidence for selective adjustments of inhibitory control in a variant of the stop signal task. AB - The ability to inhibit actions inappropriate for the context is essential for meeting the shifting demands of complex environments. The stop signal task (SST) has been used in many previous studies to examine the interactions between go and stop responses in a cognitively demanding task involving attention, conflict resolution, and motor plan selection. The current study uses a variant of the SST, in which the continue signal instructs participants to proceed with the go response they were preparing. Reaction times (RTs) on continue trials were bimodally distributed, suggesting that an aspect of inhibition was involved in at least some of the trials. We investigated whether the cognitive processes delaying the generation of a behavioural response on continue trials are the same as for stop trials. We found improvement of stop signal reaction times (SSRTs) following stop trials, but the decrease in continue signal reaction times (CSRTs) was not significant. No improvement in either SSRT or CSRT was found following continue trials, suggesting that activation of the processes delaying the response on continue trials is insufficient to drive subsequent adjustments in SSRT or CSRT. In addition, go RTs only slowed following stop trials. These effects may suggest the presence of a selective learning process, which requires that the initial inhibition captured by SSRT and CSRT be combined with recognition of the stop signal specifically to affect subsequent performance. PMID- 29589786 TI - A randomized controlled trial comparing the Thompson hemiarthroplasty with the Exeter polished tapered stem and Unitrax modular head in the treatment of displaced intracapsular fractures of the hip. AB - Aims: This study aimed to compare the change in health-related quality of life of patients receiving a traditional cemented monoblock Thompson hemiarthroplasty compared with a modern cemented modular polished-taper stemmed hemiarthroplasty for displaced intracapsular hip fractures. Patients and Methods: This was a pragmatic, multicentre, multisurgeon, two-arm, parallel group, randomized standard-of-care controlled trial. It was embedded within the WHiTE Comprehensive Cohort Study. The sample size was 964 patients. The setting was five National Health Service Trauma Hospitals in England. A total of 964 patients over 60 years of age who required hemiarthroplasty of the hip between February 2015 and March 2016 were included. A standardized measure of health outcome, the EuroQol (EQ-5D 5L) questionnaire, was carried out on admission and at four months following the operation. Results: Of the 964 patients enrolled, 482 died or were lost to follow up (50%). No significant differences were noted in EQ-5D between groups, with a mean difference at four months of 0.037 in favour of the Exeter/Unitrax implant (95% confidence interval (CI) 0.014 to 0.087, p = 0.156), rising to 0.045 (95% CI 0.007 to 0.098, p = 0.09) when patients who died were excluded. The minimum clinically important difference for EQ-5D-5L used in this study is 0.08, therefore any benefit between implants is unlikely to be noticeable to the patient. There was no difference in mortality or mobility score. Conclusion: Allowing for the high rate of loss to follow-up, the use of the traditional Thompson hemiarthroplasty in the treatment of the displaced intracapsular hip fracture shows no difference in health outcome when compared with a modern cemented hemiarthroplasty.

AB - The purpose of this study was to compare the level of pain control achieved with 8 versus 10 minute lockout intervals in adult patients who received patient controlled analgesia (PCA) within 24 hours of surgery. There was no difference in pain in the first 72 hours between the 8 minute and 10 minutes group. Additionally, there was no difference in time to first PCA regimen change or a composite outcome of adverse events. PMID- 29589793 TI - Young Africans' social representations of sexual abuse of power in their HIV related creative narratives, 2005-2014: cultural scripts and applied possibilities. AB - The sexual abuse of power is a form of sexual coercion in which individuals - typically male - use their positions of authority to obtain sex. We analysed social representations of sexual abuse of power in a sample of 1,446 narratives about HIV written by young Africans between 2005 and 2014. The narratives were prepared at five different points in time (2005, 2008, 2011, 2013 and 2014) by authors aged 10-24 in urban and rural areas of Swaziland, Kenya, South-East Nigeria, Burkina Faso and Senegal. We combined three analytical approaches: descriptive statistics of quantifiable characteristics of the narratives, thematic data analysis and a narrative-based approach. Analysis revealed two underlying cultural scripts describing the sexual abuse of power between (a) teachers and female students, and (b) male employers and domestic workers. Cross national variation was evident in the emphasis authors placed on socio-contextual inequalities, particularly poverty, and on individual level blame. While a minority of Nigerian and Burkinabe authors depicted female characters creatively exercising agency and avoiding unwanted sex, overall there was little critique of underlying assumptions of male sexual entitlement and female responsibility for controlling male sexuality in the context of unequal control of resources. We outline recommendations for strategies to deconstruct these harmful scripts. PMID- 29589794 TI - Adding a Parent to the Brain Tumor Team: Evaluating a Peer Support Intervention for Parents of Children With Brain Tumors. AB - Childhood brain tumors often present profound challenges to patients and families. To address these challenges, the California Chapter of the Pediatric Brain Tumor Foundation provides hospital-based support services to parents of children with brain tumors from a Veteran Parent (VP). This mixed-methods, cross sectional study was designed to evaluate the effectiveness of the intervention using validated tools to compare parental resilience and impact of illness on the family between parents who met with the VP and those who did not. Two-tailed t tests assessed significant differences in scores on the PedsQL Family Impact module and Connor-Davidson Resilience Scale (CD-RISC-25). Additional qualitative data gleaned from focus groups with stakeholders (health care providers and parents) were analyzed using key constructs of social support theory with Atlas.ti. Although there were no significant differences in overall scores on the PedsQL Family Impact module or CD-RISC-25 between groups, parents in the intervention group scored better on items related to handling difficult decisions and painful feelings. Overarching themes emerged from focus groups around participants' experiences with the program and included informational and emotional support, peer parent relatedness, changed outlook, and empowerment. Results reveal the impact of peer parent support and need for emotional and instrumental support. PMID- 29589795 TI - Ethical considerations with regard to adolescent consent in the perioperative setting: Talking points for anaesthetic practitioners. AB - The legal and ethical issues surrounding the care of children and young people in the perioperative setting are often vague and an anaesthetic practitioner could find themselves inadequately prepared for any issues that may arise. This paper details the case of an adolescent who withdrew her consent to surgery whilst in the anaesthetic room. It raises questions about Gillick Competency and whether the use of restraint is ever justified. PMID- 29589796 TI - Child-Mother Agreement on Experiences of School Bullying Involvement in Children With ADHD. AB - OBJECTIVE: To examine the levels of agreement between the reports of 452 children and their mothers on children's experiences of bullying involvement at school and investigate the factors influencing the levels of agreement in children with ADHD. METHOD: The levels of agreement between children's and mothers' reports were examined. The influence of age, sex, ADHD symptoms, and psychiatric comorbidities on the levels of agreement was also examined. RESULTS: The results indicated low agreement on the experiences of bullying involvement in child mother ADHD dyads. Age and hyperactivity-impulsivity, oppositional, depressive, and anxiety symptoms significantly influenced the levels of agreement on the victimization of physical bullying. Age significantly influenced the levels of agreement on the perpetration of physical bullying. CONCLUSION: Multiple sources of information are required when clinicians assess the experiences of bullying involvement at school in children with ADHD. The factors influencing the levels of agreement should be considered. PMID- 29589797 TI - ADHD Endophenotypes in Caribbean Families. AB - OBJECTIVE: The aim of this study is to contrast the genetics of neuropsychological tasks in individuals from nuclear families clustering ADHD in a Caribbean community. METHOD: We recruited and clinically characterized 408 individuals using an extensive battery of neuropsychological tasks. The genetic variance underpinning these tasks was estimated by heritability. A predictive framework for ADHD diagnosis was derived using these tasks. RESULTS: We found that individuals with ADHD differed from controls in tasks of mental control, visuospatial ability, visuoverbal memory, phonological and verbal fluency, verbal and semantic fluency, cognitive flexibility, and cognitive ability. Among them, tasks of mental control, visuoverbal memory, phonological fluency, semantic verbal fluency, and intelligence had a significant heritability. A predictive model of ADHD diagnosis using these endophenotypes yields remarkable classification rate, sensitivity, specificity, and precision values (above 80%). CONCLUSION: We have dissected new cognitive endophenotypes in ADHD that can be suitable to assess the neurobiological and genetic basis of ADHD. PMID- 29589799 TI - Lesbians' experiences and attitudes towards parenthood in Greece. AB - Same-sex parenthood is controversial subject. In this paper, we provide insights into the attitudes and experiences of self-reported lesbians regarding parenthood or the prospect of becoming a parent in the current Greek social and cultural context. In Greece, lesbians are not allowed access to in vitro fertilisation (IVF), while a solitary ('single') woman is allowed access for medical reasons. Fifty-nine (59) semi-structured in-depth interviews were conducted with women. What emerged from our data was a clear trend for participants to wish to have their own biological children based mostly on the belief that pregnancy would lead to a sense of self-completeness and/or fulfilment. Women also reported the negative impact of prejudice and social oppression on their reproductive autonomy. Interviewees reported that their reproductive choices were negatively influenced by their family and the wider socio-cultural environment. Even within a semi-permissive legal framework, impaired social acceptance of lesbian parenthood prohibits lesbians from becoming mothers. A major reason responsible for the positive attitude of most participants to shared biological motherhood was an altruistic attitude towards their partners. PMID- 29589798 TI - A latent class analysis of substance use and culture among gay, bisexual and other men who have sex with men. AB - Assessments of gay and bisexual men's substance use often obscures salient sociocultural and identity-related experiences related to how they use drugs. Latent class analysis was used to examine how patterns of substance use represent the social, economic and identity-related experiences of this population. Participants were sexually active gay and bisexual men (including other men who have sex with men), aged >= 16 years, living in Metro Vancouver (n = 774). LCA indicators included all substances used in the past six months self-reported by more than 30 men. Model selection was made with consideration to model parsimony, interpretability and optimisation of statistical criteria. Multinomial regression identified factors associated with class membership. A six-class solution was identified representing: 'assorted drug use' (4.5%); 'club drug use' (9.5%); 'street drug use' (12.1%); 'sex drug use' (11.4%); 'conventional drug use' (i.e. tobacco, alcohol, marijuana; 25.9%); and 'limited drug use' (36.7%). Factors associated with class membership included age, sexual orientation, annual income, occupation, income from drug sales, housing stability, group sex event participation, gay bars/clubs attendance, sensation seeking and escape motivation. These results highlight the need for programmes and policies that seek to lessen social disparities and account for social distinctions among this population. PMID- 29589800 TI - TeleMental Health: Standards, Reimbursement, and Interstate Practice [Formula: see text]. AB - BACKGROUND: TeleMental Health (TMH) is gaining widespread acceptance in the United States. OBJECTIVE: Summarize current evidence regarding TMH risks and benefits, standards of care, practice guidelines, reimbursement, and interstate practice issues pertinent to psychiatric nurses and consumers. DESIGN: A targeted review of literature, current practice, and TMH websites was generated using the following key search words: clinical outcomes, practice guidelines, regulations, interstate practice, and reimbursement for TMH. A search of government and professional organization websites and a literature review of PubMed and PsychINFO databases was limited to the past 15 years. RESULTS: Studies demonstrate TMH services are equal in efficacy to that provided in face-to-face encounters and preferred by some populations. Current TMH practice guidelines, reimbursement, and regulatory issues are reviewed. CONCLUSIONS: Providers, including psychiatric advanced practice registered nurses, can use TMH to effectively address the growing need for mental health services, although regulatory, licensure, and clinical issues must be addressed prior to offering TMH services. PMID- 29589801 TI - Psychometric properties of the pathological dissociation measures among Chinese - a pilot study using online methods. AB - PURPOSE: Pathological dissociation (PD) is an easily overlooked phenomenon in the mental health field. Standardized assessment is important for identifying dissociative symptoms and disorders. However, the use of PD measures in Chinese cultures needs investigation. This pilot study investigated the psychometric properties of three PD measures among Hong Kong Chinese. METHODS: The psychometric properties of the Dissociative Experiences Scale-Taxon, the 5-item Somatoform Dissociation Questionnaire, and the Self-Report Version of the Dissociative Disorders Interview Schedule (SR-DDIS) were evaluated using online methods in Hong Kong. RESULTS: The PD measures exhibited adequate to excellent internal consistency. The PD measures were negatively related to family support and can discriminate between participants with and without self-reported childhood abuse. There was excellent agreement between the online SR-DDIS results and the clinical diagnoses for presence of any dissociative disorder (DD) versus no DD. The DDs group scored significantly higher on PD measures than the depression group and the college student group. DISCUSSION: The initial findings suggest that PD can be assessed online in Hong Kong. Further investigation is necessary. PMID- 29589802 TI - The dependence of broadband ultrasound attenuation on phase interference in thin plates of variable thickness and curvature: a comparison of experimental measurement and computer simulation. AB - The measurement of broadband ultrasound attenuation describes the linear increase in ultrasound attenuation with frequency (dB/MHz); this is generally performed at the calcaneus, consisting of a high proportion of metabolically active cancellous bone. Although broadband ultrasound attenuation is not routinely implemented within clinical management since it cannot provide a reliable estimation of bone mineral density and hence clinical definition of osteopenia and osteoporosis, it offers a reliable means to predict osteoporotic fracture risk. One of the potential factors that can influence the accuracy of broadband ultrasound attenuation measurement is the effect of cortical end plates. This study aimed to explore this, performing a comparison of experimental study and computer simulation prediction. A total of three categories of thin discs were three dimensional (3D) printed to replicate cortical shells of (1) variable constant thickness (planar), (2) variable constant thickness (curved), and (3) variable thickness. A through-transmission technique was used, where two single-element, unfocused, 1 MHz broadband transducers, as utilised clinically, were positioned coaxially in a cylindrical holder and immersed in water. Both quantitative and qualitative analyses demonstrated that broadband ultrasound attenuation measurements of the 'planar' and 'curved' discs were not statistically different (p-values > 0.01). A cyclic relationship between broadband ultrasound attenuation and disc thickness was observed; this was replicated within a computer simulation of phase interference created by a double-reflection echo within each disc (R2 = 97.0%). Variable-thickness discs provided broadband ultrasound attenuation measurements ranging between 31.6 +/- 0.1 and 40.60 +/- 0.1 dB/MHz. Again applying the double-reflection echo simulation, a high level of agreement between experimental and simulation was recorded (R2 = 93.4%). This study indicates that the cortical end plate can significantly affect the broadband ultrasound attenuation measurement of cancellous bone as a result of phase interference and, therefore, warrants further investigation to minimise its effect on clinical assessment. PMID- 29589803 TI - Psychometric Evaluation of the Symptoms of Dementia Screener (SDS) in a Geriatric Primary Care Population. AB - OBJECTIVES: The Symptoms of Dementia Screener (SDS) is an 11-item scale developed to screen for cognitive impairment. We aim to evaluate the psychometric properties of the SDS for use in primary care. METHODS: We analyzed data from 192 patients: 25 not impaired, 42 with mild cognitive impairment (MCI), and 125 with dementia. Cronbach's reliability, convergent validity, and clinical utility were examined. The SDS was investigated at the item level using binary two-parameter model item response theory (IRT) techniques. RESULTS: The SDS demonstrated good reliability (11 items; alpha = .74). We found negative correlations between SDS and the Mattis DRS-2 (r = -.523, p < .01). Receiver operating characteristic (ROC) curves demonstrated acceptable clinical utility for detecting MCI and dementia with sensitivities and specificities of 83% and 52% for MCI; 78.4% and 84% for dementia, and 91% and 52% for any impairment. IRT analyses revealed 10 out of 11 items were moderately to very highly related to underlying latent factors of impairment. CONCLUSIONS: The SDS demonstrates good psychometric properties and is useful for detecting cognitive impairment in primary care settings. CLINICAL IMPLICATIONS: The SDS is an effective screening tool that does not require special training for its use in primary care. A positive screen indicates a need for further cognitive testing. PMID- 29589804 TI - Age-dependent physiological changes, medicines and sex-influenced types of falls. AB - : Background/Study context: We investigated various parameters related to falls including age-dependent physiological changes, regular medicine use and different types of falls experienced. There is a lack of research investigating the impact of health status, sex, polypharmacy and ageing on different types of falls such as unspecified fall on the same level, mechanical fall on the same level relating to slipping, tripping or loosing balance, fall from a chair, vehicle and fall as a result of syncope, fall from steps or stairs and fall from the height. METHODS: The study included a random sample of 250 older patients, which comprised 10% of the total number of patients (n = 2,492), admitted to a large-scale academic hospital following a fall. Patients' medicine and illness history, types of falls, liver, renal and sensory function were collected. Univariate analysis was used to examine associations between the type of fall and explanatory variables, followed by multinominal logistic regression analysis. RESULTS: There was a significant association between the type of fall and sex, p = 0.01, and between the type of fall and regular medicine use, p = 0.002. The multinominal logistic regression analysis revealed that the full model, which considered all explanatory variables together, was statistically significant, p < 0.001. The strongest predictor of all types of falls except 'fall from the height' was female sex followed by the regular medicine use. CONCLUSION: This study identified predictors for various types of falls in older people; the strongest predictor being a female sex followed by regular medicine use. Based on these findings, the medicine prescribing practice in this older population must be carefully reviewed.

AB - Hyaluronan (HA) constitutes the most abundant extracellular matrix component during brain development, only to become a minor component rapidly after birth and in adulthood to remain in specified regions. HA signaling has been associated with several neurological disorders, yet the impact of HA signaling at the blood brain barrier (BBB) function remains undocumented. In this study, we investigated the impact of HA on BBB properties using human-induced pluripotent stem cell (iPSC) -derived and primary human and rat BMECs. The impact of HA signaling on developmental and mature BMECs was assessed by measuring changes in TEER, permeability, BMECs markers (GLUT1, tight junction proteins, P-gp) expression and localization, CD44 expression and hyaluronan levels. In general, HA treatment decreased barrier function and reduced P-gp activity with effects being more prominent upon treatment with oligomeric forms of HA (oHA). Such effects were exacerbated when applied during BMEC differentiation phase (considered as developmental BBB). We noted a hyaluronidase activity as well as an increase in CD44 expression during prolonged oxygen-glucose deprivation stress. Inhibition of HA signaling by antibody blockade of CD44 abrogated the detrimental effects of HA treatment. These results suggest the importance of HA signaling through CD44 on BBB properties. PMID- 29589806 TI - How physiotherapists perceive, interpret, and respond to the ethical dimensions of practice: A qualitative study. AB - The profile and reach of physiotherapy has expanded in areas of extended scope of practice, and broader engagement with population needs beyond the individual treatment encounter. These changes raise increasingly complex ethical challenges evidenced by growth in physiotherapy-based ethics studies and discussions. This paper examines how a broad cross section of Australian physiotherapists perceive, interpret, and respond to ethical challenges in their work contexts and how professional codes of conduct are used in their practice. Using an interpretive qualitative methodology, purposive sampling of 88 members of national clinical special interest groups were recruited for focus group discussions. Narrative based and thematic data analysis identified ethical challenges as emerging from specific clinical contexts, and influenced by health organizations, funding policies, workplace relationships, and individually held perspectives. Five themes were developed to represent these findings: (1) the working environment, (2) balancing diverse needs and expectation, (3) defining ethics, (4) striving to act ethically, and (5) talking about ethics. The results portray a diverse and complex ethical landscape where therapists encounter and grapple with ethical questions emerging from the impact of funding models and policies affecting clinical work, expanding boundaries and scope of practice and changing professional roles and relationships. Codes of conduct were described as foundational ethical knowledge but not always helpful for "in the moment" ethical decision-making. Based on this research, we suggest how codes of conduct, educators, and professional associations could cultivate and nurture ethics capability in physiotherapy practitioners for these contemporary challenges. PMID- 29589807 TI - The Effect of Vaccine Literacy on Parental Trust and Intention to Vaccinate after a Major Vaccine Scandal. AB - Health literacy, and more specifically vaccine literacy, might be an important factor in reducing the negative effects of exposure to misleading reports on vaccination. This study explores the association between vaccine literacy and vaccination-related outcomes after misleading reports on a scandal concerning locally produced childhood vaccines had emerged in 2016 in China. Data for this study came from a cross-sectional survey, which was conducted in April 2016 in Hangzhou, China. Data were collected in kindergartens and community health centers among parents of children up to 6 years of age. Data were analyzed for 1864 participants. Binary logistic regression models showed that, after controlling for socio-demographics and children's age, parents who had better vaccine literacy (<0.05) were more likely to trust and choose domestically produced vaccines, which account for about 95% of the total vaccinations in China. This study provides evidence on a still largely understudied relationship between vaccine literacy and vaccination-related outcomes. Findings might suggest that higher literacy levels could reduce some of the negative effects of being exposed to misleading information on vaccination, eventually leading to less vaccination hesitancy. PMID- 29589808 TI - On the Role of Cognitive Abilities in Second Language Vowel Learning. AB - This study investigated the role of different cognitive abilities-inhibitory control, attention control, phonological short-term memory (PSTM), and acoustic short-term memory (AM)-in second language (L2) vowel learning. The participants were 40 Azerbaijani learners of Standard Southern British English. Their perception of L2 vowels was tested through a perceptual discrimination task before and after five sessions of high-variability phonetic training. Inhibitory control was significantly correlated with gains from training in the discrimination of L2 vowel pairs. However, there were no significant correlations between attention control, AM, PSTM, and gains from training. These findings suggest the potential role of inhibitory control in L2 phonological learning. We suggest that inhibitory control facilitates the processing of L2 sounds by allowing learners to ignore the interfering information from L1 during training, leading to better L2 segmental learning. PMID- 29589809 TI - Breast cancer literacy and health beliefs related to breast cancer screening among American Indian women. AB - The purpose of this article is to examine the health beliefs and literacy about breast cancer and their relationship with breast cancer screening among American Indian (AI) women. Using the Health Belief Model (HBM) and hierarchical logistic regression with data from a sample of 286 AI female adults residing in the Northern Plains, we found that greater awareness of breast cancer screening was linked to breast cancer screening practices. However, perceived barriers, one of the HBM constructs, prevented such screening practices. This study suggested that culturally relevant HBM factors should be targeted when developing culturally sensitive breast cancer prevention efforts. PMID- 29589810 TI - Visuomotor learning is dependent on direction-specific error saliency. AB - People perceive better in cardinal directions compared with oblique ones. This directional effect, called oblique effect, has been documented in perception studies for a long time. However, typical motor studies do not differentiate learning in different directions. In this study we identify a significant directional effect in motor learning using visuomotor rotation paradigms. We find that adaptation to visual perturbations yields more savings when both initial learning and relearning are performed in cardinal directions than in oblique directions. We hypothesize that this directional effect arises from relatively higher error saliency in cardinal directions. Consistent with this hypothesis, we successfully increased savings in the oblique directions, which showed no saving effect before, by enhancing the error saliency with augmented visual feedback during learning. Our findings suggest that movement direction plays an important role in motor learning, especially when learning signals are direction specific. Our results also provide new insights about the role of motor errors in the formation and retrieval of motor memory and practical implications for promoting learning in motor rehabilitation and athletic training. NEW & NOTEWORTHY People perceive better when the stimulus is in cardinal directions than in oblique directions. Whether a similar directional effect exists in motor learning is unknown. Using a motor learning paradigm, we show that people relearn to compensate for a previously encountered perturbation faster when they move in cardinal directions than when they move in oblique directions. Further experimentation supports that this motor directional effect likely results from better sensory saliency of motor errors in cardinal directions. PMID- 29589811 TI - Differential effects of adaptation on odor discrimination. AB - Adaptation of neural responses is ubiquitous in sensory systems and can potentially facilitate many important computational functions. Here we examined this issue with a well-constrained computational model of the early olfactory circuits. In the insect olfactory system, the responses of olfactory receptor neurons (ORNs) on the antennae adapt over time. We found that strong adaptation of sensory input is important for rapidly detecting a fresher stimulus encountered in the presence of other background cues and for faithfully representing its identity. However, when the overlapping odorants were chemically similar, we found that adaptation could alter the representation of these odorants to emphasize only distinguishing features. This work demonstrates novel roles for peripheral neurons during olfactory processing in complex environments. NEW & NOTEWORTHY Olfactory systems face the problem of distinguishing salient information from a complex olfactory environment. The neural representations of specific odor sources should be consistent regardless of the background. How are olfactory representations robust to varying environmental interference? We show that in locusts the extraction of salient information begins in the periphery. Olfactory receptor neurons adapt in response to odorants. Adaptation can provide a computational mechanism allowing novel odorant components to be highlighted during complex stimuli. PMID- 29589813 TI - Proximal and distal modulation of neural activity by spatially confined optogenetic activation with an integrated high-density optoelectrode. AB - Optogenetic manipulations are widely used for investigating the contribution of genetically identified cell types to behavior. Simultaneous electrophysiological recordings are less common, although they are critical for characterizing the specific impact of optogenetic manipulations on neural circuits in vivo. This is at least in part because combining photostimulation with large-scale electrophysiological recordings remains technically challenging, which also poses a limitation for performing extracellular identification experiments. Currently available interfaces that guide light of the appropriate wavelength into the brain combined with an electrophysiological modality suffer from various drawbacks such as a bulky size, low spatial resolution, heat dissipation, or photovoltaic artifacts. To address these challenges, we have designed and fabricated an integrated ultrathin neural interface with 12 optical outputs and 24 electrodes. We used the device to measure the effect of localized stimulation in the anterior olfactory cortex, a paleocortical structure involved in olfactory processing. Our experiments in adult mice demonstrate that because of its small dimensions, our novel tool causes far less tissue damage than commercially available devices. Moreover, optical stimulation and recording can be performed simultaneously, with no measurable electrical artifact during optical stimulation. Importantly, optical stimulation can be confined to small volumes with approximately single-cortical layer thickness. Finally, we find that even highly localized optical stimulation causes inhibition at more distant sites. NEW & NOTEWORTHY In this study, we establish a novel tool for simultaneous extracellular recording and optogenetic photostimulation. Because the device is built using established microchip technology, it can be fabricated with high reproducibility and reliability. We further show that even very localized stimulation affects neural firing far beyond the stimulation site. This demonstrates the difficulty in predicting circuit-level effects of optogenetic manipulations and highlights the importance of closely monitoring neural activity in optogenetic experiments. PMID- 29589812 TI - Muscle coactivation: definitions, mechanisms, and functions. AB - The phenomenon of agonist-antagonist muscle coactivation is discussed with respect to its consequences for movement mechanics (such as increasing joint apparent stiffness, facilitating faster movements, and effects on action stability), implication for movement optimization, and involvement of different neurophysiological structures. Effects of coactivation on movement stability are ambiguous and depend on the effector representing a kinematic chain with a fixed origin or free origin. Furthermore, coactivation is discussed within the framework of the equilibrium-point hypothesis and the idea of hierarchical control with spatial referent coordinates. Relations of muscle coactivation to changes in one of the basic commands, the c-command, are discussed and illustrated. A hypothesis is suggested that agonist-antagonist coactivation reflects a deliberate neural control strategy to preserve effector-level control and avoid making it degenerate and facing the necessity to control at the level of signals to individual muscles. This strategy, in particular, allows stabilizing motor actions by covaried adjustments in spaces of control variables. This hypothesis is able to account for higher levels of coactivation in young healthy persons performing challenging tasks and across various populations with movement impairments. PMID- 29589814 TI - Gap encoding by parvalbumin-expressing interneurons in auditory cortex. AB - Synaptic inhibition shapes the temporal processing of sounds in auditory cortex, but the contribution of specific inhibitory cell types to temporal processing remains unclear. We recorded from parvalbumin-expressing (PV+) interneurons in auditory cortex to determine how they encode gaps in noise, a model of temporal processing more generally. We found that PV+ cells had stronger and more prevalent on-responses, off-responses, and postresponse suppression compared with presumed pyramidal cells. We summarize this pattern of differences as "deeper modulation" of gap responses in PV+ cells. Response latencies were also markedly faster for PV+ cells. We found a similar pattern of deeper modulation and faster latencies for responses to white noise bursts, suggesting that these are general properties of on- and off-responses in PV+ cells rather than specific features of gap encoding. These findings are consistent with a role for PV+ cells in providing dynamic gain control by pooling local activity. NEW & NOTEWORTHY We found that parvalbumin-expressing (PV+) interneurons in auditory cortex showed more deeply modulated responses to both gaps in noise and bursts of noise, suggesting that they are optimized for the rapid detection of stimulus transients. PMID- 29589815 TI - Primary sensorimotor cortex exhibits complex dependencies of spike-field coherence on neuronal firing rates, field power, and behavior. AB - Spike-field coherence (SFC) is widely used to assess cortico-cortical interactions during sensorimotor behavioral tasks by measuring the consistency of the relative phases between the spike train of a neuron and the concurrent local field potentials (LFPs). Interpretations of SFC as a measure of functional connectivity are complicated by theoretical work suggesting that estimates of SFC depend on overall neuronal activity. We evaluated the dependence of SFC on neuronal firing rates, LFP power, and behavior in the primary motor (MIo) and primary somatosensory (SIo) areas of the orofacial sensorimotor cortex of monkeys ( Macaca mulatta) during performance of a tongue-protrusion task. Although we occasionally observed monotonically increasing linear relationships between coherence and firing rate, we most often found highly complex, nonmonotonic relationships in both SIo and MIo and sometimes even found that coherence decreased with increasing firing rate. The lack of linear relationships was also true for both LFP power and tongue-protrusive force. Moreover, the ratio between maximal firing rate and the firing rate at peak coherence deviated significantly from unity, indicating that MIo and SIo neurons achieved maximal SFC at a submaximal level of spiking. Overall, these results point to complex relationships of SFC to firing rates, LFP power, and behavior during sensorimotor cortico-cortical interactions: coherence is a measure of functional connectivity whose magnitude is not a mere monotonic reflection of changes in firing rate, LFP power, or the relevantly controlled behavioral parameter. NEW & NOTEWORTHY The concern that estimates of spike-field coherence depend on the firing rates of single neurons has influenced analytical methods employed by experimental studies investigating the functional interactions between cortical areas. Our study shows that the overwhelming majority of the estimated spike-field coherence exhibited complex relations with firing rates of neurons in the orofacial sensorimotor cortex. The lack of monotonic relations was also evident after testing the influence of local field potential power and force on spike-field coherence. PMID- 29589816 TI - Modulation of complex spike activity differs between zebrin-positive and negative Purkinje cells in the pigeon cerebellum. AB - The cerebellum is organized into parasagittal zones defined by its climbing and mossy fiber inputs, efferent projections, and Purkinje cell (PC) response properties. Additionally, parasagittal stripes can be visualized with molecular markers, such as heterogeneous expression of the isoenzyme zebrin II (ZII), where sagittal stripes of high ZII expression (ZII+) are interdigitated with stripes of low ZII expression (ZII-). In the pigeon vestibulocerebellum, a ZII+/- stripe pair represents a functional unit, insofar as both ZII+ and ZII- PCs within a stripe pair respond best to the same pattern of optic flow. In the present study, we attempted to determine whether there were any differences in the responses between ZII+ and ZII- PCs within a functional unit in response to optic flow stimuli. In pigeons of either sex, we recorded complex spike activity (CSA) from PCs in response to optic flow, marked recording sites with a fluorescent tracer, and determined the ZII identity of recorded PCs by immunohistochemistry. We found that CSA of ZII+ PCs showed a greater depth of modulation in response to the preferred optic flow pattern compared with ZII- PCs. We suggest that these differences in the depth of modulation to optic flow stimuli are due to differences in the connectivity of ZII+ and ZII- PCs within a functional unit. Specifically, ZII+ PCs project to areas of the vestibular nuclei that provide inhibitory feedback to the inferior olive, whereas ZII- PCs do not. NEW & NOTEWORTHY Although the cerebellum appears to be a uniform structure, Purkinje cells (PCs) are heterogeneous and can be categorized on the basis of the expression of molecular markers. These phenotypes are conserved across species, but the significance is undetermined. PCs in the vestibulocerebellum encode optic flow resulting from self-motion, and those that express the molecular marker zebrin II (ZII+) exhibit more sensitivity to optic flow than those that do not express zebrin II (ZII-).

AB - Parents of children newly diagnosed with cancer must acquire new knowledge and skills in order to safely care for their child at home. Institutional variation exists in the methods and content used by nurses in providing the initial education. The goal of this project was to develop a checklist, standardized across institutions, to guide nursing education provided to parents of children newly diagnosed with cancer. A team of 21 members (19 nurses and 2 parent advocates) used current hospital educational checklists, expert consensus recommendations, and a series of iterative activities and discussions to develop one standardized checklist. The final checklist specifies primary topics that are essential to teach prior to the initial hospital discharge, secondary topics that should be discussed within the first month after the cancer diagnosis, and tertiary topics that should be discussed prior to completion of therapy. This checklist is designed to guide education and will set the stage for future studies to identify effective teaching strategies that optimize the educational process for parents of children newly diagnosed with cancer. PMID- 29589817 TI - Neurophysiological changes in the visuomotor network after practicing a motor task. AB - Although it is well appreciated that practicing a motor task updates the associated internal model, it is still unknown how the cortical oscillations linked with the motor action change with practice. The present study investigates the short-term changes (e.g., fast motor learning) in the alpha- and beta-event related desynchronizations (ERD) associated with the production of a motor action. To this end, we used magnetoencephalography to identify changes in the alpha- and beta-ERD in healthy adults after participants practiced a novel isometric ankle plantarflexion target-matching task. After practicing, the participants matched the targets faster and had improved accuracy, faster force production, and a reduced amount of variability in the force output when trying to match the target. Parallel with the behavioral results, the strength of the beta-ERD across the motor-planning and execution stages was reduced after practice in the sensorimotor and occipital cortexes. No pre/postpractice changes were found in the alpha-ERD during motor planning or execution. Together, these outcomes suggest that fast motor learning is associated with a decrease in beta ERD power. The decreased strength likely reflects a more refined motor plan, a reduction in neural resources needed to perform the task, and/or an enhancement of the processes that are involved in the visuomotor transformations that occur before the onset of the motor action. These results may augment the development of neurologically based practice strategies and/or lead to new practice strategies that increase motor learning. NEW & NOTEWORTHY We aimed to determine the effects of practice on the movement-related cortical oscillatory activity. Following practice, we found that the performance of the ankle plantarflexion target-matching task improved and the power of the beta-oscillations decreased in the sensorimotor and occipital cortexes. These novel findings capture the beta oscillatory activity changes in the sensorimotor and occipital cortexes that are coupled with behavioral changes to demonstrate the effects of motor learning. PMID- 29589820 TI - Text Messaging to Improve Disease Management in Patients With Painful Diabetic Peripheral Neuropathy. AB - Purpose The purpose of the study was to determine the impact of educational text messages on diabetes self-management activities and outcomes in patients with painful diabetic peripheral neuropathy (pDPN). Methods Patients with pDPN identified from a large integrated health system who agreed to participate were randomized to 6 months of usual care (UC) or UC plus twice-daily diabetes self management text messages (UC+TxtM). Outcomes included the Pain Numerical Rating Scale, Summary of Diabetes Self-Care Activities (SDSCA), questions on diabetes health beliefs, and glycated hemoglobin (A1C). Changes from baseline were evaluated at 6 months and compared between groups. Results Demographic characteristics were balanced between groups (N = 62; 53% female, mean age = 63 years, 94% type 2 diabetes), as were baseline measures. After 6 months, pain decreased with UC+TxtM from 6.3 to 5.5 and with UC from 6.5 to 6.0, with no difference between groups. UC+TxtM but not UC was associated with significant improvements from baseline on all SDSCA subscales. On diabetes health beliefs, UC+TxtM patients reported significantly increased benefits and reduced barriers and susceptibility relative to UC at 6 months. A1C declined in both groups, but neither change was significant relative to baseline. Conclusions Patients with pDPN who receive twice-daily text messages regarding diabetes management reported reduced pain relative to baseline, although this change was not significant compared with usual care. In addition, text messaging was associated with increased self-management activities and improved diabetes health beliefs and total self-care. These results warrant further investigation. PMID- 29589821 TI - The 2017 Diabetes Educator and the Diabetes Self-Management Education National Practice Survey. AB - Purpose The American Association of Diabetes Educators conducts the National Practice Survey (NPS) biennially to document current practice in diabetes education in the United States. The purpose of the study is to obtain insight about factors influencing the work of the diabetes educator. Method The 2017 NPS was comprised of 100 questions covering diabetes educator demographics, profile populations of people with diabetes, practice information, program accreditation, program curriculum, staffing, education delivery methods, data collection, and reporting. The basic survey consisted of 22 questions using branch logic, from which respondents were then directed to questions tailored to their particular practice setting, enabling them to answer only a relevant subset of the remaining questions. The web-based survey was sent to approximately 32 000 individuals who were either members of the American Association of Diabetes Educators (AADE) or Certified Diabetes Educators (CDE) with the National Certification Board for Diabetes Educators (NCBDE) but not AADE members. Weekly reminder e-mails were sent to recipients who had not yet responded. The outreach efforts resulted in the survey being completed by 4696 individuals, a 17% response rate yielding 95% confidence that these responses are within +/-5% accuracy. Results Diabetes Self Management Education and Support (DSMES) continues to be a field dominated by women (95%). Diabetes educators represent a diverse health care profession, with educators indicating most commonly that their primary discipline is nursing (48%), nutrition (38%), and pharmacy (7%). When asked about credentials, 82.6% indicated that they held a CDE, 3.8% held the Board Certified-Advanced Diabetes Management (BC-ADM) credential, and 16.5% held neither the CDE nor the BC-ADM. Nearly 75% characterized their role as a diabetes educator as providing direct patient care. DSMES continued to be provided in a varied array of settings to educationally, socioeconomically, and racially diverse patient populations. DSMES was delivered using a number of different educational strategies. Diabetes educators have direct influence in care and services that people with diabetes receive. Conclusions The results of the 2017 NPS demonstrate that diabetes educators are meeting the needs of varied populations in various practice settings. They are working with individuals with type 1 and type 2 diabetes, those at risk for diabetes, and women with gestational diabetes and are involved in recommending, implementing, and providing key referrals and recommendations for diabetes care, including insulin initiation, titration, medication adjustments, recommendations on devices, and technology. Identified areas for improvement include needs for increased racial and ethnic diversity in the workforce, recruiting young professionals, drawing practice approaches from related disciplines (eg, mental health and disability rehabilitation), and encouraging tracking of more areas of outcomes data. Diabetes educators are playing an increasingly central role within multidisciplinary care teams with people at risk for diabetes, those who have diabetes, and those with other chronic conditions.

AB - The Hypoviridae, comprising one genus, Hypovirus, is a family of capsidless viruses with positive-sense, ssRNA genomes of 9.1-12.7 kb that possess either a single large ORF or two ORFs. The ORFs appear to be translated from genomic RNA by non-canonical mechanisms, i.e. internal ribosome entry site-mediated and stop/restart translation. Hypoviruses have been detected in ascomycetous or basidiomycetous filamentous fungi, and are considered to be replicated in host Golgi-derived, lipid vesicles that contain their dsRNA as a replicative form. Some hypoviruses induce hypovirulence to host fungi, while others do not. This is a summary of the current ICTV report on the taxonomy of the Hypoviridae, which is available at www.ictv.global/report/hypoviridae. PMID- 29589827 TI - The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae). AB - Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts. Here, we report that in the ichneumonid group of koinobiont spider-ectoparasitoids ("polysphinctines"), several putatively ancestral taxa (clade I here), parasitic on ground-dwelling RTA-spiders (a group characterised by retrolateral tibial apophysis on male palpal tibiae), lay their eggs in a specific way. They tightly bend their metasoma above the spider's cephalothorax, touching the carapace with the dorsal side of the ovipositor apically ("dorsal-press"). The egg slips out from the middle part of the ventral side of the ovipositor and moves towards its apex with the parted lower valves acting as rails. Deposition occurs as the parasitoid draws the ovipositor backwards from under the egg. Oviposition upon the tough carapace of the cephalothorax, presumably less palatable than the abdomen, is conserved in these taxa, and presumed adaptive through avoiding physical damage to the developing parasitoid. This specific way of oviposition is reversed in the putatively derived clade of polysphinctines (clade II here) parasitic on Araneoidea spiders with aerial webs, which is already known. They bend their metasoma along the spider's abdomen, grasping the abdomen with their fore/mid legs, pressing the ventral tip of the metasoma and the lower valves of the ovipositor against the abdomen ("ventral-press"). The egg is expelled through an expansion of the lower valves, which is developed only in this clade and evident in most species, onto the softer and presumably more nutritious abdomen. PMID- 29589828 TI - Structural and functional properties of a probabilistic model of neuronal connectivity in a simple locomotor network. AB - Although, in most animals, brain connectivity varies between individuals, behaviour is often similar across a species. What fundamental structural properties are shared across individual networks that define this behaviour? We describe a probabilistic model of connectivity in the hatchling Xenopus tadpole spinal cord which, when combined with a spiking model, reliably produces rhythmic activity corresponding to swimming. The probabilistic model allows calculation of structural characteristics that reflect common network properties, independent of individual network realisations. We use the structural characteristics to study examples of neuronal dynamics, in the complete network and various sub-networks, and this allows us to explain the basis for key experimental findings, and make predictions for experiments. We also study how structural and functional features differ between detailed anatomical connectomes and those generated by our new, simpler, model (meta-model). PMID- 29589829 TI - Comprehensive machine learning analysis of Hydra behavior reveals a stable basal behavioral repertoire. AB - Animal behavior has been studied for centuries, but few efficient methods are available to automatically identify and classify it. Quantitative behavioral studies have been hindered by the subjective and imprecise nature of human observation, and the slow speed of annotating behavioral data. Here, we developed an automatic behavior analysis pipeline for the cnidarian Hydra vulgaris using machine learning. We imaged freely behaving Hydra, extracted motion and shape features from the videos, and constructed a dictionary of visual features to classify pre-defined behaviors. We also identified unannotated behaviors with unsupervised methods. Using this analysis pipeline, we quantified 6 basic behaviors and found surprisingly similar behavior statistics across animals within the same species, regardless of experimental conditions. Our analysis indicates that the fundamental behavioral repertoire of Hydra is stable. This robustness could reflect a homeostatic neural control of "housekeeping" behaviors which could have been already present in the earliest nervous systems. PMID- 29589830 TI - Transmission genetics of drug-resistant hepatitis C virus. AB - Antiviral development is plagued by drug resistance and genetic barriers to resistance are needed. For HIV and hepatitis C virus (HCV), combination therapy has proved life-saving. The targets of direct-acting antivirals for HCV infection are NS3/4A protease, NS5A phosphoprotein and NS5B polymerase. Differential visualization of drug-resistant and -susceptible RNA genomes within cells revealed that resistant variants of NS3/4A protease and NS5A phosphoprotein are cis-dominant, ensuring their direct selection from complex environments. Confocal microscopy revealed that RNA replication complexes are genome-specific, rationalizing the non-interaction of wild-type and variant products. No HCV antivirals yet display the dominance of drug susceptibility shown for capsid proteins of other viruses. However, effective inhibitors of HCV polymerase exact such high fitness costs for drug resistance that stable genome selection is not observed. Barriers to drug resistance vary with target biochemistry and detailed analysis of these barriers should lead to the use of fewer drugs. PMID- 29589831 TI - Cellular tolerance at the u-opioid receptor is phosphorylation dependent. AB - Phosphorylation of the MU-opioid receptor (MOR) is known as a key step in desensitization and internalization but the role in the development of long-term tolerance at the cellular level is not known. Viral expression of wild type (exWT) and mutant MORs, where all phosphorylation sites on the C-terminus (Total Phosphorylation Deficient (TPD)) were mutated to alanine, were examined in locus coeruleus neurons in a MOR knockout rat. Both receptors activated potassium conductance similar to endogenous receptors in wild type animals. The exWT receptors, like endogenous receptors, acutely desensitized, internalized and, after chronic morphine treatment, displayed signs of tolerance. However, TPD receptors did not desensitize or internalize with agonist treatment. In addition the TPD receptors did not develop cellular tolerance following chronic morphine treatment. Thus C-terminal phosphorylation is necessary for the expression of acute desensitization, trafficking and one sign of long-term tolerance to morphine at the cellular level. PMID- 29589832 TI - Acute Traumatic Coagulopathy: The Value of Histone in Pediatric Trauma Patients. AB - OBJECTIVE: Acute traumatic coagulopathy occurs after trauma with impairment of hemostasis and activation of fibrinolysis. Some endogenous substances may play roles in this failure of the coagulation system. Extracellular histone is one such molecule that has recently attracted attention. This study investigated the association between plasma histone-complexed DNA (hcDNA) fragments and coagulation abnormalities in pediatric trauma patients. MATERIALS AND METHODS: This prospective case-control study was conducted in pediatric patients with trauma. Fifty trauma patients and 30 healthy controls were enrolled. Demographic data, anatomic injury characteristics, coagulation parameters, computerized tomography findings, trauma, and International Society on Thrombosis and Haemostasis disseminated intravascular coagulation (ISTH DIC) scores were recorded. Blood samples for hcDNA were collected and assessed by enzyme-linked immunosorbent assay. RESULTS: Thirty-two patients had multiple trauma, while 18 patients had isolated brain injury. hcDNA levels were significantly higher in trauma patients than healthy controls (0.474 AU and 0.145 AU, respectively). There was an association between plasma hcDNA levels and trauma severity. Thirteen patients had acute coagulopathy of trauma shock (ACoTS). ACoTS patients had higher plasma histone levels than those without ACoTS (0.703 AU and 0.398 AU, respectively). Plasma hcDNA levels were positively correlated with the ISTH DIC score and length of stay in the intensive care unit and were negatively correlated with fibrinogen level. CONCLUSION: This study indicated that hcDNA levels were increased in pediatric trauma patients and associated with the early phase of coagulopathy. Further studies are needed to clarify the role of hcDNA levels in mortality and disseminated intravascular coagulation.

Materials and Methods: We evaluated disease outcome, progression-free survival (PFS), overall survival as the endpoint, and clinical and laboratory factors affecting the outcome of 185 DLBCL patients who had received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone therapy during 2004-2014. Results: The study group included 121 men and 64 women with a median age of 66 years minimum maximum: 21-83 years. In univariate analysis, factors independently associated with worse PFS were Eastern Cooperative Oncology Group performance status >=2, Ann Arbor stage III or IV, anemia with Hb levels of <10 g/dL, and serum albumin of <3.5 g/dL. In multivariate analysis, anemia with Hb levels of <10 g/dL and Ann Arbor stage III or IV were found to be international index-independent prognostic factors (hazard ratio: 2.4; p=0.04). Conclusion: Anemia is an independent prognostic marker of poor outcome in DLBCL patients. Hb can be an easily available prognostic marker for risk stratification in these patients.

AB - OBJECTIVE: Plasma cell dyscrasias (PCDs) are disorders of plasma cells having in common the production of a monoclonal M-protein. They include a spectrum of conditions that may represent a natural progression of the same disease from monoclonal gammopathy of unknown significance to asymptomatic and symptomatic multiple myeloma, plasma cell leukemia, and Waldenstrom's macroglobulinemia. In PCDs, the immune system is actively suppressed through the secretion of suppressive factors and the recruitment of immune suppressive subpopulations. In this study, we examined the expression of two subpopulations of cells with immunosuppressive activity, monocytic myeloid-derived suppressor cells (MDSCs) and monocytes expressing latency-associated peptide (LAP), in patients with different PCDs and in healthy volunteers. MATERIALS AND METHODS: A total of 27 consecutive patients with PCDs were included in this study. Nineteen healthy volunteers served as controls. RESULTS: We observed a hierarchical correlation between disease activity and the presence of monocytes with immunosuppressive activity. CONCLUSION: These results suggest that MDSCs and monocytes expressing LAP have diverging roles in PCDs and may perhaps serve as biomarkers of tumor activity and bulk.

AB - SNC80 was designed as a highly selective nonpeptide delta opioid receptor (DOR) agonist. Antidepressant-like and antinociceptive effects of this compound were demonstrated in animal models. Naltrindole was synthetized as a highly selective DOR antagonist. Its antitussive and antinociceptive effects were reported. Observed effects of SNC80 and naltrindole may be accompanied by changes in neuronal excitability including modulation of voltage-dependent ion channels. We investigated possible DOR-independent modulation of neuronal sodium, calcium and potassium currents by both agents. NG108-15 cells lacking expression of DOR protein were used as model of neuronal cells. Cells were differentiated into neuronal phenotype by exposure to dibutyryl cyclic-AMP (dbcAMP). Lack of DORs expression in NG108-15 cells and the presence of DOR expression in brain and neuronal cultures were demonstrated by Western blot analysis. Both SNC80 and naltrindole exerted low to moderate modulatory effects on voltage-dependent ion currents. SNC80 weakly inhibited sodium current, potentiated calcium current, and did not act on potassium channels. Naltrindole inhibited sodium current, did not act on calcium current and inhibited potassium current at a high concentration. Such effects should be taken into account when these compounds are used for investigation of DOR-mediated signaling pathways. PMID- 29589836 TI - Laser induced calcium oscillations in fluorescent calcium imaging. AB - Phototoxicity is the most common problem investigators may encounter when performing live cell imaging. It develops due to excess laser exposure of cells loaded with fluorophores and can lead to often overlooked but significant artifacts, such as massive increase of intracellular Ca2+ concentration, which would make data interpretation problematic. Because information about laser- and dye-related changes in cytoplasmic calcium concentration is very limited, we aimed to describe this phenomenon to help investigators using laser scanning confocal microscopy in a non-invasive way. Therefore, in the present study we evaluated fluorescent fluctuations, which evolved in Fluo-3/4/8 loaded mouse pancreatic acinar cells during very low intensity laser excitation. We demonstrate that after standard loading procedure (2 uM Fluo-3/4/8-AM, 30 min at room temperature), applying 488 nm laser at as low as ca. 10 uW incident laser power (0.18 uW/um2) at 1 Hz caused repetitive, 2-3 fold elevations of the resting intracellular fluorescence. The first latency and the pattern of the fluorescence fluctuations were laser power dependent and were related to Ca2+-release from intracellular stores, as they were abolished by BAPTA-AM treatment in Ca2+-free medium, but were not diminished by the reactive oxygen species (ROS) scavenger DMPO. Worryingly enough, the qualitative and quantitative features of the Ca2+ waves were practically indistinguishable from the responses evoked by secretagogue stimulation. Since using similar imaging conditions, a number of other cell types were reported to display spontaneous Ca2+ oscillations, we propose strategies to distinguish the real signals from artifacts.

AB - The canine remnant kidney model is fundamental to understanding the relationship between hypertension and chronic kidney disease (CKD). This study aimed to create a 1/16 remnant kidney model and to determine whether blood pressure (BP) control affects the progression of CKD. A group of dogs received BP treatment (group A) and another received BP treatment except for the first 2 weeks (group B). The remnant kidney model was induced using a two-step subtotal nephrectomy method; dogs received antihypertensive therapy. Systolic BP, blood urea nitrogen, serum creatinine, urinary protein, and creatinine levels were measured weekly. Kidney tissues were obtained at the conclusion of the study. Systolic BP was controlled to <160 mmHg in both groups for 18 weeks, except for the first 2 weeks in group B. Proteinuria was elevated after renal ligation in both groups, but gradually increased in group B and decreased in group A (p = 0.009). Blood urea nitrogen (p = 0.014) and creatinine (p = 0.020) levels were higher in group B than in group A. More histological damage was observed in group B than in group A. Induction of 1/16 nephrectomy successfully established CKD. Control of BP may be important to prevent or control the progression of CKD in dogs. PMID- 29589838 TI - Electronic structure and charge transport in nonstoichiometric tantalum oxide. AB - The atomic and electronic structure of nonstoichiometric oxygen-deficient tantalum oxide TaO x<2.5 grown by ion beam sputtering deposition was studied. The TaO x film content was analyzed by x-ray photoelectron spectroscopy and by quantum-chemistry simulation. TaO x is composed of Ta2O5, metallic tantalum clusters and tantalum suboxides. A method for evaluating the stoichiometry parameter of TaO x from the comparison of experimental and theoretical photoelectron valence band spectra is proposed. The charge transport properties of TaO x were experimentally studied and the transport mechanism was quantitatively analyzed with four theoretical dielectric conductivity models. It was found that the charge transport in almost stoichiometric and nonstoichiometric tantalum oxide can be consistently described by the phonon assisted tunneling between traps.

AB - A stereospecific three-component domino reaction between glycals, alkylidene malonate and aldehydes catalyzed by Yb(OTf)3 is described. Multi-substituted cis fused perhydropyrano[2,3-b]pyran derivatives were obtained with high diastereoselectivity. PMID- 29589839 TI - PPARgamma deacetylation dissociates thiazolidinedione's metabolic benefits from its adverse effects. AB - Thiazolidinediones (TZDs) are PPARgamma agonists with potent insulin-sensitizing effects. However, their use has been curtailed by substantial adverse effects on weight, bone, heart, and hemodynamic balance. TZDs induce the deacetylation of PPARgamma on K268 and K293 to cause the browning of white adipocytes. Here, we show that targeted PPARgamma mutations resulting in constitutive deacetylation (K268R/K293R, 2KR) increased energy expenditure and protected from visceral adiposity and diet-induced obesity by augmenting brown remodeling of white adipose tissues. Strikingly, when 2KR mice were treated with rosiglitazone, they maintained the insulin-sensitizing, glucose-lowering response to TZDs, while displaying little, if any, adverse effects on fat deposition, bone density, fluid retention, and cardiac hypertrophy. Thus, deacetylation appears to fulfill the goal of dissociating the metabolic benefits of PPARgamma activation from its adverse effects. Strategies to leverage PPARgamma deacetylation may lead to the design of safer, more effective agonists of this nuclear receptor in the treatment of metabolic diseases. PMID- 29589840 TI - The Atypical Chemokine Receptor ACKR2 is Protective Against Sepsis. AB - Sepsis is a systemic inflammatory response as a result of uncontrolled infections. Neutrophils are the first cells to reach the primary sites of infection, and chemokines play a key role in recruiting neutrophils. However, in sepsis chemokines could also contribute to neutrophil infiltration to vital organs leading to multiple organ failure. ACKR2 is an atypical chemokine receptor, which can remove and degrade inflammatory CC chemokines. The role of ACK2 in sepsis is unknown. Using a model of cecal ligation and puncture (CLP), we demonstrate here that ACKR2 deficient () mice exhibited a significant reduction in the survival rate compared with similarly treated wild-type (WT) mice. However, neutrophil migration to the peritoneal cavity and bacterial load were similar between WT and ACKR2 mice during CLP. In contrast, ACKR2 mice showed increased neutrophil infiltration and elevated CC chemokine levels in the lung, kidney, and heart compared with the WT mice. In addition, ACKR2 mice also showed more severe lesions in the lung and kidney than those in the WT mice. Consistent with these results, WT mice under nonsevere sepsis (90% survival) had higher expression of ACKR2 in these organs than mice under severe sepsis (no survival). Finally, the lungs from septic patients showed increased number of ACKR2 cells compared with those of nonseptic patients. Our data indicate that ACKR2 may have a protective role during sepsis, and the absence of ACKR2 leads to exacerbated chemokine accumulation, neutrophil infiltration, and damage to vital organs. PMID- 29589842 TI - Lyophobicity may not be the main driving force for long chain surfactants from the bulk phase to the interface. AB - According to the Traube rule, a surfactant with a longer alkane chain is more hydrophobic so its tendency to be driven from a polar solvent to a less polar interface is higher. In this work, we revisited this topic by studying the adsorption of quaternary ammonium salts and carboxylic acids with various alkane chain lengths at the hexadecane-water interface. The adsorption free energies of the surfactants at this oil-water interface from the polar (aqueous solution) or nonpolar phase (hexadecane) were estimated from second harmonic generation measurements. The variation of the free energies per methylene group in the bulk phase, at the oil-water interface and at the air-water interface revealed that there are different interactions between the alkane chains of the surfactants in different environments. The chain-chain interaction at the hexadecane-water interface is lower than that at the air-water interface. The driving force for the alkane chains to adsorb at the oil-water interface from the oil phase is close to that from the aqueous phase. This observation reveals that the chain chain interaction rather than the lyophobicity of the solute with respect to the solvent is the main contributor to the adsorption free energy. This is the first experimental comparison of the free energies of the alkane chains in oil, in water, at the air-water interface and at the oil-water interface. These results provide information for studying the interactions of hydrophobic species in different environments. This work also provides a method for estimating the solvation energy of some head groups in surfactants. PMID- 29589844 TI - Predicting cancer cell invasion by single-cell physical phenotyping. AB - The physical properties of cells are promising biomarkers for cancer diagnosis and prognosis. Here we determine the physical phenotypes that best distinguish human cancer cell lines, and their relationship to cell invasion. We use the high throughput, single-cell microfluidic method, quantitative deformability cytometry (q-DC), to measure six physical phenotypes including elastic modulus, cell fluidity, transit time, entry time, cell size, and maximum strain at rates of 102 cells per second. By training a k-nearest neighbor machine learning algorithm, we demonstrate that multiparameter analysis of physical phenotypes enhances the accuracy of classifying cancer cell lines compared to single parameters alone. We also discover a set of four physical phenotypes that predict invasion; using these four parameters, we generate the physical phenotype model of invasion by training a multiple linear regression model with experimental data from a set of human ovarian cancer cells that overexpress a panel of tumor suppressor microRNAs. We validate the model by predicting invasion based on measured physical phenotypes of breast and ovarian human cancer cell lines that are subject to genetic or pharmacologic perturbations. Taken together, our results highlight how physical phenotypes of single cells provide a biomarker to predict the invasion of cancer cells. PMID- 29589843 TI - PEDOT doped with algal, mammalian and synthetic dopants: polymer properties, protein and cell interactions, and influence of electrical stimulation on neuronal cell differentiation. AB - Poly(3,4-ethylenedioxythiophene) (PEDOT) films were electrochemically polymerised with several synthetic (dodecylbenzosulfonic acid (DBSA)) and biological (dextran sulphate (DS), chondroitin sulphate (CS), alginic acid (ALG) and ulvan (ULV)) dopant anions, and their physical, mechanical and electrochemical properties characterised. PEDOT films incorporating the biological dopants ALG and ULV produced films of the greatest surface roughness (46 +/- 5.1 and 31 +/- 1.9 nm, respectively), and demonstrated significantly lower shear modulus values relative to all other PEDOT films (2.1 +/- 0.1 and 1.2 +/- 0.2 MPa, respectively). Quartz crystal microgravimetry was used to study the adsorption of the important extracellular matrix protein fibronectin, revealing protein adsorption to be greatest on PEDOT doped with DS, followed by DBSA, ULV, CS and ALG. Electrical stimulation experiments applying a pulsed current using a biphasic waveform (250 Hz) were undertaken using PEDOT doped with either DBSA or ULV. Electrical stimulation had a significant influence on cell morphology and cell differentiation for PEDOT films with either dopant incorporated, with the degree of branching per cell increased by 10.5* on PEDOT-DBSA and 6.5* on PEDOT-ULV relative to unstimulated cells, and mean neurite length per cell increasing 2.6* and 2.2* on stimulated vs. unstimulated PEDOT-DBSA and PEDOT-ULV, respectively. We demonstrate the cytocompatibility of synthetic and biologically doped PEDOT biomaterials, including the new algal derived polysaccharide dopant ulvan, which, along with DBSA doped PEDOT, is shown to significantly enhance the differentiation of PC12 neuronal cells under electrical stimulation. PMID- 29589845 TI - Copper-catalyzed synthesis of thiazol-2-yl ethers from oxime acetates and xanthates under redox-neutral conditions. AB - A novel copper-catalyzed annulation of oxime acetates and xanthates for the synthesis of thiazol-2-yl ethers with remarkable regioselectivity has been developed. Various oxime acetates, whether derived from aryl ketones or alkyl ketones, or natural product cores are suitable for this conversion. Unique dihydrothiazoles were also obtained when both reaction sites were methine. Mechanistic studies indicated that imino copper(iii) intermediates were involved. In addition, this protocol proceeded under redox-neutral conditions and did not require additives or ligands. PMID- 29589846 TI - Nanocellulose templated growth of ultra-small bismuth nanoparticles for enhanced radiation therapy. AB - An unmet need in nanomedicine is to prepare biocompatible and renal clearable nanoparticles by controlling the diameter, composition and surface properties of the nanoparticles. This paper reports cellulose nanofiber templated synthesis of ultra-small bismuth nanoparticles, and their uses in enhanced X-ray radiation therapy. The interstitial spaces between adjacent fibers are the adsorption sites of bismuth ions and also stabilize nanoparticles generated by chemical reduction. The sizes of nanoparticles are tailored in the 2-10 nm range using cellulose nanofibers with various amounts of carboxyl groups. In vitro cytotoxicity, reactive oxygen species (ROS) and in vivo animal tests with tumor-bearing mice are studied in order to enhance X-ray radiation therapy using cellulose nanofiber templated bismuth nanoparticles. Bismuth nanoparticles show strong X-ray attenuation ability, concentration-dependent cytotoxicity and high level production of ROS upon X-ray exposure, which is consistent with enhanced cellular damage and retarded growth of tumors in animals. PMID- 29589847 TI - The stability limits of highly active nitrogen doped carbon ORR nano-catalysts: a mechanistic study of degradation reactions. AB - A new approach in electrode catalysis bearing immense potential for electrochemical technologies is the prospect of carbon-based electrodes. Pristine carbon nanostructures are relatively inert and modifications like nitrogen doping are known for their beneficial effects on the electrochemical activity of carbon nanomaterials in both alkaline and acidic media. However, the long-term stability of these materials, especially in an acidic environment, is rarely mentioned. Here, we evaluate the stability and long-term degradation of nitrogen doped graphene flakes as an oxygen reduction electrocatalyst with theoretical and experimental techniques. We assume that nitrogen dopants in the graphene sheet interact with e- and H+ at the electrode-electrolyte interface, leading to NH3 scission and continuous catalyst deactivation. With Density Functional Theory calculations, NH3 scission pathways of pyridinic, graphitic and pyrrolic nitrogen species were analyzed and compared under different operating conditions which are relevant for low and intermediate temperature fuel cells. The computational results are correlated with electrochemical measurements in solid acid fuel cells in a humidified oxygen environment at 240 degrees C. PMID- 29589848 TI - Mechanical pressure, surface excess, and polar order of a dilute rod-like nanoswimmer suspension: role of swimmer-wall interactions. AB - The mechanical pressure, surface excess, and polar order of a dilute rod-like nanoswimmer suspension confined by two parallel plates are explored by dissipative particle dynamics. The accumulation and preferred orientation of swimmers near the walls are distinctly shown through the density and polar order distributions for various active force, Fa, values and rod lengths. As Fa is increased, it is interesting to observe that there exists a maximum of the polar order, revealing that the dominant mechanism of the swimmer behavior can be altered by the coupling between the active force and the rod-wall interaction. As a result, the influences of the active force on the swim pressure Pi(w)a contributed by the swimmers directly and the surface excess Gamma* can be classified into two scaling regimes, natural rotation (weak propulsion) and forced rotation (strong propulsion). Pi(w)a and Gamma* are proportional to Fa2 in the former regime but become proportional to Fa in the latter regime. For all rod wall repulsions, the swim pressure of active rods in confined systems Pi(w)a always differs from that in unbounded systems Pi(b)a which is simply proportional to Fa2 associated with the active diffusivity. That is, unlike thermal equilibrium systems, Pi(w)a is not a state function because of the presence of the wall-torque. PMID- 29589849 TI - Growth modes and chiral selectivity of single-walled carbon nanotubes. AB - Chemical vapor deposition synthesis of single-walled carbon nanotubes, using an Fe catalyst, and alternating methane and carbon monoxide as carbon feedstocks, leads to the reversible formation of junctions between tubes of different diameters. Combined with an atomistic modeling of the tube/catalyst interface, this shows that the ratio of diameters of the tube and its seeding particle, denoting the growth mode, depends on the carbon fraction inside the catalyst. With carbon monoxide, nanoparticles are strongly carbon enriched, and tend to dewet the tube, in a perpendicular growth mode. Cross-checking our results with the available reports from the literature of the last decade strongly suggests that these latter conditions should favor the near armchair chiral selectivity observed empirically. PMID- 29589850 TI - Reconstituting donor T cells increase their biomass following hematopoietic stem cell transplantation. AB - In this study, we used a rapid, highly-sensitive, single-cell biomass measurement method, Live Cell Interferometry (LCI), to measure biomass in populations of CD3 + T cells isolated from hematopoietic stem cell transplant (SCT) patients at various times pre- and post-transplant (days 0-100). CD3 + T cell 'mass spectra' were obtained from five autologous and 20 allogenic transplant recipients. We found a pronounced rise in median T cell biomass (+25%; p <0.001) shortly after transplant (day 14), which moderated by day 60. Further, the inter-patient and intra-patient cell masses were most variable at days 14 and 30 post-transplant. T cell biomass trends were similar in both autologous and allogenic transplant recipients. These data suggest that T cell biomass changes are associated with immune reconstitution occurring in the first few weeks post-transplant. To our knowledge, this is the first time single-cell biomass measurements have been studied in human clinical trials. With refinement, these data may prove useful in guiding the withdrawal of immunosuppression following SCT, reducing the likelihood of Graft-Versus-Host Disease or cancer relapse occurring.

AB - A facile and large-scale fluidized bed reaction route was introduced for the first time to prepare crystalline embedded amorphous silicon nanoparticles with an average size of 50 nm as anode materials for lithium-ion batteries. By increasing the operating potential to control the electrochemically active degree, the resulting sample showed excellent cycle stability with a high capacity retention of 94.7% after 200 cycles at 1 A g-1 in the voltage range of 0.12-2.00 V.

AB - Markovnikov or anti-Markovnikov selective thiol-ene click (TEC) reactions and the synthesis of beta-hydroxysulfides via aerial dioxygen activation are prevalent C S bond forming reactions of styrenes and thiophenols. Herein, by choosing appropriate environments using solvents with additives or neat conditions, any one of these three reactions was achieved exclusively in excellent yields. PMID- 29589856 TI - Probing the mechanism of thermally driven thiol-Michael dynamic covalent chemistry. AB - The kinetics and mechanism of the thermally activated dynamic covalent exchange of thiol-Michael adducts is investigated. A model system of thiol-Michael adducts between thiophenol and phenylvinylketone derivatives and adducts between 2 mercaptoethanol phenylvinylketone derivatives in N,N-dimethylformamide (DMF) at elevated temperatures is used to probe the underlying exchange mechanism. The kinetic data show negligible free Michael acceptor, which is consistent with the highly efficient thiol-Michael reaction being a "click"-like reaction that significantly favors the adduct form. At elevated temperatures of 90 degrees C in DMF the thiol-Michael adducts reach equilibrium after 24 h, although equilibration did not occur within 24 h at 60 degrees C or 75 degrees C, and negligible exchange occurs under ambient conditions. A kinetic model was developed to describe the dynamic covalent exchange and equilibration. The experimental and simulation kinetic data of dynamic covalent exchange are consistent with the thiol-Michael adducts undergoing a retro-Michael reaction, followed by subsequent addition of a free thiol to the liberated Michael acceptor. Kinetic analysis is consistent with the fragmentation, or retro-Michael reaction, being the rate-determining step in the dynamic covalent exchange. This suggests that the key step in dynamic covalent exchange is not enhanced by addition of free thiol or free Michael acceptor, since the addition reaction is much faster than the retro-Michael reaction. This fundamental study will guide the design of organic compounds, materials, and bioconjugates that utilize the thermally activated dynamic covalent thiol-Michael linkages. PMID- 29589857 TI - Concentration-induced multi-colored emissions in carbon dots: origination from triple fluorescent centers. AB - Color-tunable carbon dots have been synthesized via a one pot hydrothermal synthesis and re-dispersed in dimethylformamide solution after purification. Structural and optical property characterizations indicate that the concentration dependent photoluminescent properties can be ascribed to the existence of multi emissive centers in the carbon dots from core states, edge states and surface states. Therefore, a multi-center fluorescent mechanism for the carbon dots has been proposed according to the preservation effect and inductive effect of the solvent. The emission wavelength of the carbon dots with different concentrations can be tuned from 585 to 514 nm under the fixed excitation of 420 nm blue light, and a warm white light-emitting diode with a CIE color coordinate at (0.42, 0.35) is fabricated on a InGaN blue chip emitting 420 nm blue light.

PMID- 29589860 TI - Seedless assembly of colloidal crystals by inverted micro-fluidic pumping. AB - We propose a simple seedless approach to assemble millimeter sized monolayer single colloidal crystals with desired orientations at predetermined locations on an unstructured charged substrate. This approach utilizes the millimeter-ranged fluid flow on the bottom glass substrate induced by an ion exchange resin (IEX) fixed on top of the closed sample cell. The fluid flow increases with decreasing height of the sample cell and increasing radius R of the IEX. For a single inverted pump, millimeter sized monolayer single crystals of hexagonal close packing can be obtained. For two closely spaced (D ~ 4R) pumps, the formed crystals have a predefined orientation along the line connecting the two IEX. By patterning IEX into different structures, colloidal crystals of different complex patterns form. The present method paves a convenient way for fabricating high quality monolayer colloidal crystals for a variety of applications. PMID- 29589862 TI - Tailored dimensionality to regulate the phase stability of inorganic cesium lead iodide perovskites. AB - Inorganic CsPbI3 perovskites have shown promising potential for achieving all inorganic photovoltaic (PV) devices. However, the black perovskite polymorph (alpha-phase) of CsPbI3 easily converts into yellow colour (delta-phase) in an ambient environment and it is only stable at high temperature (above 320 degrees C), which limits its practical application. Here we tailor the three-dimensional CsPbI3 perovskite into quasi-two-dimension through adding a large radius cation phenylethylammonium (PEA+). The incorporation of PEA+ into the CsPbI3 perovskite significantly improves the film morphology as well as the phase stability. An optimal CsxPEA1-xPbI3 perovskite film remains stable in the alpha-phase from room temperature to 250 degrees C in air and yields a power conversion efficiency of 5.7% for its solar device. The concept of using large radius cations in the 3D perovskite system provides a new perspective to further enhance the phase stability while retaining the device performance.

AB - Macrocyclic [Fe(eta5-C5H4Se)2M(eta5-C5H4R)2]2 [M = Ti (1), Zr (2), Hf (3), R = H; and M = Zr (4), Hf (5), R = tBu] were prepared and characterized by 77Se NMR spectroscopy and the crystal structures of 1-3 and 5 were determined by single crystal X-ray diffraction. The crystal structure of 4 is known and the complex is isomorphous with 5. 1-5 form mutually similar macrocyclic tetranuclear complexes in which the alternating Fe(C5H4Se)2 and M(C5H4R)2 centers are linked by selenium bridges. The thermogravimetric analysis (TGA) of 1-3 under a helium atmosphere indicated that the complexes undergo a two-step decomposition upon heating. The final products were identified using powder X-ray diffraction as FexMSe2, indicating their potential as single-source precursors for functional materials.

AB - Following the recent discovery of the [A]Mn(H2POO)3 (H2POO- = hypophosphite) perovskite family, we report the A = [NH2(CH3)2]+ (dimethylammonium, DMA) member. This phase shows an unusually large unit cell due to the position of the A-site cation within the perovskite cage windows rather than the centre, as is the norm. We discuss the tendency of the hypophosphite perovskite skeleton to accommodate differently shaped A-site cations through the generation of unconventional tilts and columnar shifts, then enumerate these tilts and shifts for all known [A]Mn(H2POO)3 phases. PMID- 29589866 TI - Glutathione-induced amino-activatable micellar photosensitization platform for synergistic redox modulation and photodynamic therapy. AB - In recent years, photodynamic therapy (PDT) was considered to be a promising cancer treatment modality, however, the therapeutic efficiency was often attenuated by the intrinsic antioxidant defense systems. Herein, a kind of novel glutathione-induced amino-activatable micelle was designed, which was expected to weaken the antioxidant capacity and in the meantime release the photosensitizer by the exhaustion of intracellular glutathione (GSH). The amphiphilic poly(ethylene glycol)-(2-((2,4-dinitro-N-(ethyl) phenyl)sulfonamido) ethyl methacrylate) copolymers were synthesized and assembled into a core-shell nano structure in aqueous media. The nano structure demonstrated high sensitivity and selectivity to bio-thiols in vitro and in vivo. Subsequently, pheophorbide a (PhA) was encapsulated as the model photosensitizer. Upon internalization by HepG2 cells, the strongly electron-withdrawing 2,4-dinitrobenzenesulfonyl groups on the PADEE segments were readily cleaved by GSH, during which time the secondary amino groups (pKb = 11.32) were recovered and completely protonated, leading to disassembly of the micelles and rapid release of PhA. Importantly, the consumption of GSH weakened the intracellular antioxidant capacity, resulting in the synergetic accumulation of reactive oxygen species (ROS) under laser irradiation. As a result, this micellar photosensitization system could overcome the antioxidant capacity of advanced stage tumors through a simultaneous extrinsic and intrinsic strategy, facilitating therapeutic efficiency. These results demonstrate that the as-designed micelles provide a versatile photosensitization platform for on-demand PDT.

AB - Luminescent ionic liquids, based on anionic Pt(ii) complexes, were developed. Depending on the cyclometalating ligands used, they exhibit thermochromic luminescence with different colours.

PMID- 29589871 TI - Temporal dynamics of circadian phase shifting response to consecutive night shifts in healthcare workers: role of light-dark exposure. AB - KEY POINTS: Shift work is highly prevalent and is associated with significant adverse health impacts. There is substantial inter-individual variability in the way the circadian clock responds to changing shift cycles. The mechanisms underlying this variability are not well understood. We tested the hypothesis that light-dark exposure is a significant contributor to this variability; when combined with diurnal preference, the relative timing of light exposure accounted for 71% of individual variability in circadian phase response to night shift work. These results will drive development of personalised approaches to manage circadian disruption among shift workers and other vulnerable populations to potentially reduce the increased risk of disease in these populations. ABSTRACT: Night shift workers show highly variable rates of circadian adaptation. This study examined the relationship between light exposure patterns and the magnitude of circadian phase resetting in response to night shift work. In 21 participants (nursing and medical staff in an intensive care unit) circadian phase was measured using 6-sulphatoxymelatonin at baseline (day/evening shifts or days off) and after 3-4 consecutive night shifts. Daily light exposure was examined relative to individual circadian phase to quantify light intensity in the phase delay and phase advance portions of the light phase response curve (PRC). There was substantial inter-individual variability in the direction and magnitude of phase shift after three or four consecutive night shifts (mean phase delay -1:08 +/- 1:31 h; range -3:43 h delay to +3:07 h phase advance). The relative difference in the distribution of light relative to the PRC combined with diurnal preference accounted for 71% of the variability in phase shift. Regression analysis incorporating these factors estimated phase shift to within +/-60 min in 85% of participants. No participants met criteria for partial adaptation to night work after three or four consecutive night shifts. Our findings provide evidence that the phase resetting that does occur is based on individual light exposure patterns relative to an individual's baseline circadian phase. Thus, a 'one size fits all' approach to promoting adaptation to shift work using light therapy, implemented without knowledge of circadian phase, may not be efficacious for all individuals. PMID- 29589873 TI - Cost-effectiveness of hydromorphone for severe opioid use disorder: findings from the SALOME randomized clinical trial. AB - BACKGROUND AND AIMS: Previous research has found diacetylmorphine, delivered under supervision, to be cost-effective in the treatment of severe opioid use disorder, but diacetylmorphine is not available in many settings. The Study to Assess Long-term Opioid Maintenance Effectiveness (SALOME) randomized controlled trial provided evidence that injectable hydromorphone is non-inferior to diacetylmorphine. The current study aimed to compare the cost-effectiveness of hydromorphone directly with diacetylmorphine and indirectly with methadone maintenance treatment. DESIGN: A within-trial analysis was conducted using the patient level data from the 6-month, double-blind, non-inferiority SALOME trial. A life-time analysis extrapolated costs and outcomes using a decision analytical cohort model. The model incorporated data from a previous trial to include an indirect comparison to methadone maintenance. SETTING: A supervised clinic in Vancouver, British Columbia, Canada. PARTICIPANTS: A total of 202 long-term street opioid injectors who had at least two attempts at treatment, including one with methadone (or other substitution), were randomized to hydromorphone (n = 100) or diacetylmorphine (n = 102). MEASUREMENTS: We measured the utilization of drugs, visits to health professionals, hospitalizations, criminal activity, mortality and quality of life. This enabled us to estimate incremental costs, quality-adjusted life years (QALYs) and cost-effectiveness ratios from a societal perspective. Sensitivity analyses considered different sources of evidence, assumptions and perspectives. FINDINGS: The within-trial analysis found hydromorphone provided similar QALYs to diacetylmorphine [0.377, 95% confidence interval (CI) = 0.361-0.393 versus 0.375, 95% CI = 0.357-0.391], but accumulated marginally greater costs [$49 830 ($28 401-73 637) versus $34 320 ($21 780-55 998)]. The life-time analysis suggested that both diacetylmorphine and hydromorphone provide more benefits than methadone [8.4 (7.4-9.5) and 8.3 (7.2 9.5) versus 7.4 (6.5-8.3) QALYs] at lower cost [$1.01 million ($0.6-1.59 million) and $1.02 million ($0.72-1.51 million) versus $1.15 million ($0.71-1.84 million)]. CONCLUSIONS: In patients with severe opioid use disorder enrolled into the SALOME trial, injectable hydromorphone provided similar outcomes to injectable diacetylmorphine. Modelling outcomes during a patient's life-time suggested that injectable hydromorphone might provide greater benefit than methadone alone and may be cost-saving, with drug costs being offset by costs saved from reduced involvement in criminal activity.

AB - Cigarette smoking (CS) adversely affects the physiologic function of endothelial progenitor, hematopoietic stem and progenitor cells. However, the effect of CS on the ability of adipose stem/stromal cells (ASC) to promote vasculogenesis and rescue perfusion in the context of ischemia is unknown. To evaluate this, ASC from nonsmokers (nCS-ASC) and smokers (CS-ASC), and their activity to promote perfusion in hindlimb ischemia models, as well as endothelial cell (EC) survival and vascular morphogenesis in vitro were assessed. While nCS-ASC improved perfusion in ischemic limbs, CS-ASC completely lost this therapeutic effect. In vitro vasculogenesis assays revealed that human CS-ASC and ASC from CS-exposed mice showed compromised support of EC morphogenesis into vascular tubes, and the CS-ASC secretome was less potent in supporting EC survival/proliferation. Comparative secretome analysis revealed that CS-ASC produced lower amounts of hepatocyte growth factor (HGF) and stromal cell-derived growth factor 1 (SDF-1). Conversely, CS-ASC secreted the angiostatic/pro-inflammatory factor Activin A, which was not detected in nCS-ASC conditioned media (CM). Furthermore, higher Activin A levels were measured in EC/CS-ASC cocultures than in EC/nCS-ASC cocultures. CS-ASC also responded to inflammatory cytokines with 5.2-fold increase in Activin A secretion, whereas nCS-ASC showed minimal Activin A induction. Supplementation of EC/CS-ASC cocultures with nCS-ASC CM or with recombinant vascular endothelial growth factor, HGF, or SDF-1 did not rescue vasculogenesis, whereas inhibition of Activin A expression or activity improved network formation up to the level found in EC/nCS-ASC cocultures. In conclusion, ASC of CS individuals manifest compromised in vitro vasculogenic activity as well as in vivo therapeutic activity. Stem Cells 2018;36:856-867.

AB - As a powerful regulator of cellular homeostasis and metabolism, adenosine is involved in diverse neurological processes including pain, cognition, and memory. Altered adenosine homeostasis has also been associated with several diseases such as depression, schizophrenia, or epilepsy. Based on its protective properties, adenosine has been considered as a potential therapeutic agent for various brain disorders. Since systemic application of adenosine is hampered by serious side effects such as vasodilatation and cardiac suppression, recent studies aim at improving local delivery by depots, pumps, or cell-based applications. Here, we report on the characterization of adenosine-releasing human embryonic stem cell derived neuroepithelial stem cells (long-term self-renewing neuroepithelial stem [lt-NES] cells) generated by zinc finger nuclease (ZFN)-mediated knockout of the adenosine kinase (ADK) gene. ADK-deficient lt-NES cells and their differentiated neuronal and astroglial progeny exhibit substantially elevated release of adenosine compared to control cells. Importantly, extensive adenosine release could be triggered by excitation of differentiated neuronal cultures, suggesting a potential activity-dependent regulation of adenosine supply. Thus, ZFN-modified neural stem cells might serve as a useful vehicle for the activity-dependent local therapeutic delivery of adenosine into the central nervous system.

PMID- 29589878 TI - Hepatocellular carcinoma is diagnosed at a later stage in alcoholic patients: Results of a prospective, nationwide study. AB - BACKGROUND: Recent data suggest that alcohol-related hepatocellular carcinoma (HCC) is diagnosed at a later stage. The aim of this study was to compare HCC characteristics and outcomes in an alcohol-related group (group A) and a non alcohol-related group (group NA). METHODS: A total of 1207 patients with newly diagnosed HCC were prospectively included between May 2008 and October 2009. Patients with multiple causes (alcohol plus another cause) were excluded. Patients were followed every year for 5 years. Recorded variables, including etiologies were tested as prognostic factors of survival in a multivariate Cox model after adjustments for a lead-time bias. RESULTS: In all, 894 patients were analyzed: 582 (65.1%) were in group A, and 312 (34.9%) were in group NA. Alcohol related HCC was more likely to be diffuse and detected in patients with a worse performance status and worse liver function. After adjustments for a lead-time bias, the median overall survival (OS) was 9.7 and 5.7 months in groups NA and A, respectively (P = .0002), and 5.8 and 5.0 months in alcohol-abstinent and alcohol non-abstinent groups, respectively (P = .09). The prognostic role of alcohol disappeared when survival was assessed at each Barcelona Clinic Liver Cancer (BCLC) stage. Patients with HCC detected during a cirrhosis follow-up program (n = 199 [22.3% of the whole cohort]) had increased lead time-adjusted median OS in comparison with patients with HCC diagnosed incidentally (11.7 vs 5.4 months; P < .0001). CONCLUSIONS: In comparison with patients with non-alcohol-related HCC, patients with alcohol-related HCC have reduced OS, mainly because of worse liver function and tumor characteristics at diagnosis, as attested by similar survival within each BCLC stage.

PMID- 29589895 TI - Graphene Oxide-A Tool for the Preparation of Chemically Crosslinking Free Alginate-Chitosan-Collagen Scaffolds for Bone Tissue Engineering. AB - Developing a biodegradable scaffold remains a major challenge in bone tissue engineering. This study was aimed at developing novel alginate-chitosan-collagen (SA-CS-Col)-based composite scaffolds consisting of graphene oxide (GO) to enrich porous structures, elicited by the freeze-drying technique. To characterize porosity, water absorption, and compressive modulus, GO scaffolds (SA-CS-Col-GO) were prepared with and without Ca2+-mediated crosslinking (chemical crosslinking) and analyzed using Raman, Fourier transform infrared (FTIR), X-ray diffraction (XRD), and scanning electron microscopy techniques. The incorporation of GO into the SA-CS-Col matrix increased both crosslinking density as indicated by the reduction of crystalline peaks in the XRD patterns and polyelectrolyte ion complex as confirmed by FTIR. GO scaffolds showed increased mechanical properties which were further increased for chemically crosslinked scaffolds. All scaffolds exhibited interconnected pores of 10-250 MUm range. By increasing the crosslinking density with Ca2+, a decrease in the porosity/swelling ratio was observed. Moreover, the SA-CS-Col-GO scaffold with or without chemical crosslinking was more stable as compared to SA-CS or SA-CS-Col scaffolds when placed in aqueous solution. To perform in vitro biochemical studies, mouse osteoblast cells were grown on various scaffolds and evaluated for cell proliferation by using MTT assay and mineralization and differentiation by alizarin red S staining. These measurements showed a significant increase for cells attached to the SA-CS-Col-GO scaffold compared to SA-CS or SA-CS-Col composites. However, chemical crosslinking of SA-CS-Col-GO showed no effect on the osteogenic ability of osteoblasts. These studies indicate the potential use of GO to prepare free SA-CS-Col scaffolds with preserved porous structure with elongated Col fibrils and that these composites, which are biocompatible and stable in a biological medium, could be used for application in engineering bone tissues.

AB - The peculiarities of the solid-state interaction in the HfC-Ir system have been studied within the 1000-1600 degrees C temperature range using a set of modern analytical techniques. It was stated that the interaction of HfC with iridium becomes noticeable at temperatures as low as 1000-1100 degrees C and results in the formation of HfIr3-based substitutional solid solution. The homogeneity range of the HfIr3+/- x phase was evaluated and refined as HfIr2.43-HfIr3.36. The durability of the HfIr3-based system under extreme environmental conditions was studied. It was shown that the HfIr3-based material displays excellent ablation resistance under extreme environmental conditions. The benefits of the new designed material result from its relative oxygen impermeability and special microstructure similar to superalloys. The results obtained in this work allow us to consider HfIr3 as a very promising candidate for extreme applications. PMID- 29589898 TI - Excellent Activity and Selectivity of One-Pot Synthesized Cu-SSZ-13 Catalyst in the Selective Catalytic Oxidation of Ammonia to Nitrogen. AB - One-pot synthesized Cu-SSZ-13 catalyst treated with dilute HNO3 achieved superior activity and selectivity in the selective catalytic oxidation (SCO) of NH3 to nitrogen, in comparison with other zeolite-based catalysts and most of metal oxide catalysts. Furthermore, the catalyst showed the similar or even higher catalytic activity than the partial noble-metal catalysts, and meanwhile its N2 selectivity was superior to most noble-metal catalysts. The characterization results demonstrated that more Cu2+ ions existing in Cu-SSZ-13 catalyst were advantageous to its NH3-SCO activity. The in situ DRIFTS results indicated that the reactivity of NH3 species adsorbed on Lewis and Bronsted acid sites over Cu SSZ-13-O-H catalyst depended on the reaction temperature. The results of this study suggest the one-pot synthesized Cu-SSZ-13 is a promising NH3-SCO catalyst for practical application, either mobile or stationary pollution sources. PMID- 29589897 TI - Magnetic Nanotweezers for Interrogating Biological Processes in Space and Time. AB - The ability to sense and manipulate the state of biological systems has been extensively advanced during the past decade with the help of recent developments in physical tools. Unlike standard genetic and pharmacological perturbation techniques-knockdown, overexpression, small molecule inhibition-that provide a basic on/off switching capability, these physical tools provide the capacity to control the spatial, temporal, and mechanical properties of the biological targets. Among the various physical cues, magnetism offers distinct advantages over light or electricity. Magnetic fields freely penetrate biological tissues and are already used for clinical applications. As one of the unique features, magnetic fields can be transformed into mechanical stimuli which can serve as a cue in regulating biological processes. However, their biological applications have been limited due to a lack of high-performance magnetism-to-mechanical force transducers with advanced spatiotemporal capabilities. In this Account, we present recent developments in magnetic nanotweezers (MNTs) as a useful tool for interrogating the spatiotemporal control of cells in living tissue. MNTs are composed of force-generating magnetic nanoparticles and field generators. Through proper design and the integration of individual components, MNTs deliver controlled mechanical stimulation to targeted biomolecules at any desired space and time. We first discuss about MNT configuration with different force stimulation modes. By modulating geometry of the magnetic field generator, MNTs exert pulling, dipole-dipole attraction, and rotational forces to the target specifically and quantitatively. We discuss the key physical parameters determining force magnitude, which include magnetic field strength, magnetic field gradient, magnetic moment of the magnetic particle, as well as distance between the field generator and the particle. MNTs also can be used over a wide range of biological time scales. By simply adjusting the amplitude and phase of the applied current, MNTs based on electromagnets allow for dynamic control of the magnetic field from microseconds to hours. Chemical design and the nanoscale effects of magnetic particles are also essential for optimizing MNT performance. We discuss key strategies to develop magnetic nanoparticles with improved force generation capabilities with a particular focus on the effects of size, shape, and composition of the nanoparticles. We then introduce various strategies and design considerations for target-specific biomechanical stimulations with MNTs. One-to-one particle-receptor engagement for delivering a defined force to the targeted receptor and the small size of the nanoparticles are important. Finally, we demonstrate the utility of MNTs for manipulating biological functions and activities with various spatial (single molecule/cell to organisms) and temporal resolution (microseconds to days). MNTs have the potential to be utilized in many exciting applications across diverse biological systems spanning from fundamental biology investigations of spatial and mechanical signaling dynamics at the single cell and systems levels to in vivo therapeutic applications.

AB - A broadband and lightweight microwave absorber has attracted soaring research interest because of the increasing demand for electronic reliability and defense security. Lightweight ferrites/graphene porous composites with abundant interfaces are potential high-performance absorbers owing to their balanced attenuation ability and impedance matching. Herein, we synthesized hierarchical CoFe2O4/reduced graphene oxide (CFO/rGO) nanocomposites with a porous structure via an in situ solvothermal method. The electromagnetic parameters of CFO/rGO nanocomposites can be well-adjusted by modulating the weight fraction of rGO. The hierarchical porous structure and proper electromagnetic parameters result in the enhancement of impedance matching and attenuation ability. Benefiting from the controllable composition, hierarchical porous structure, and strong synergetic effect between CFO and rGO sheets, as expected, CFO/rGO nanocomposites exhibit superior microwave absorption performance with an ultrabroad bandwidth reaching 5.8 GHz (8.3-14.1 GHz) with a thin thickness of 2.8 mm. Meanwhile, a strong reflection loss of -57.7 dB at the same thickness is achieved. Considering the outstanding microwave absorption performance, the hierarchical CFO/rGO porous nanocomposites can be employed as a high-performance microwave absorber. PMID- 29589900 TI - Cooperative Catechol-Functionalized Polypept(o)ide Brushes and Ag Nanoparticles for Combination of Protein Resistance and Antimicrobial Activity on Metal Oxide Surfaces. AB - Prevention of biofouling and microbial contamination of implanted biomedical devices is essential to maintain their functionality and biocompatibility. For this purpose, polypept(o)ide block copolymers have been developed, in which a protein-resistant polysarcosine (pSar) block is combined with a dopamine-modified poly(glutamic acid) block for surface coating and silver nanoparticles (Ag NPs) formation. In the development of a novel, versatile, and biocompatible antibacterial surface coating, block lengths pSar were varied to derive structure property relationships. Notably, the catechol moiety performs two important tasks in parallel; primarily it acts as an efficient anchoring group to metal oxide surfaces, while it furthermore induces the formation of Ag NPs. Attributing to the dual function of catechol moieties, antifouling pSar brush and antimicrobial Ag NPs can not only adhere stably on metal oxide surfaces, but also display passive antifouling and active antimicrobial activity, showing good biocompatibility simultaneously. The developed strategy seems to provide a promising platform for functional modification of biomaterials surface to preserve their performance while reducing the risk of bacterial infections. PMID- 29589902 TI - Nanoscale Investigations of alpha- and gamma-Crystal Phases in PVDF-Based Nanocomposites. AB - The impact of carbon nanotube (CNT) incorporation into semicrystalline poly(vinylidene fluoride), PVDF, was investigated at both the macro and nanoscales. A special effort was devoted to probe the local morphology and the mechanical, ferroelectric, piezoelectric, and electrical conductivity response by means of atomic force microscopy. Incorporation of CNTs mainly induces the development of the polar gamma-phase, and as a consequence, the coexistence of the gamma-phase with the most stable nonpolar alpha-phase is observed. A maximum gamma-phase content is reached at 0.7 wt % CNT loading. The spherulitic morphology of the PVDF alpha-phase is assessed, in conjunction with the lack of any ferroelectric response, while the presence of the polar gamma-phase is confirmed, owing to clear piezoresponse signals. Local piezoelectric measurements on gamma-phase domains yield a maximum effective coefficient | d33| ~ 13 pm/V, thus underlining the potential for applications of such functional PVDF-based nanocomposites in advanced piezoelectric devices. An increase in macroscopic conductivity with CNT content is observed, with a percolation threshold achieved for a composition close to 0.7 wt %. Nanoscale investigation of the electrical conductivity confirms the presence of some infinite CNT cluster homogeneously distributed over the surface. The macroscopic viscoelastic behavior of the composite reflects the reinforcing effect of CNTs, while the nanomechanical characterization yields a local contact modulus of the gamma-phase domains larger than that of its alpha-phase counterpart, in agreement with the fact that the CNTs act as gamma-phase promoters and subsequently reinforce the gamma-domains. PMID- 29589903 TI - Changes in Protein Dynamics in Escherichia coli SufS Reveal a Possible Conserved Regulatory Mechanism in Type II Cysteine Desulfurase Systems. AB - In the Suf Fe-S cluster assembly pathway, the activity of the cysteine desulfurase, SufS, is regulated by interactions with the accessory sulfotransferase protein, SufE. SufE has been shown to stimulate SufS activity, likely by inducing conformational changes in the SufS active site that promote the desulfurase step and by acting as an efficient persulfide acceptor in the transpersulfuration step. Previous results point toward an additional level of regulation through a "half-sites" mechanism that affects the stoichiometry and affinity for SufE as the dimeric SufS shifts between desulfurase and transpersulfuration activities. Investigation of the covalent persulfide intermediate of SufS by backbone amide hydrogen-deuterium exchange mass spectrometry identified two active site peptides (residues 225-236 and 356-366) and two peptides at the dimer interface of SufS (residues 88-100 and 243-255) that exhibit changes in deuterium uptake upon formation of the intermediate. Residues in these peptides are organized to form a conduit between the two active sites upon persulfide formation and include key cross-monomer interactions, suggesting they may play a role in the half-sites regulation. Three evolutionarily conserved residues at the dimer interface (R92, E96, and E250) were investigated by alanine scanning mutagenesis. Two of the substituted enzymes (E96A and E250A SufS) resulted in 6-fold increases in the value of KSufE, confirming a functional role. Re-examination of the dimer interface in reported crystal structures of SufS and the SufS homologue CsdA identified previously unnoticed residue mobility at the dimer interface. The identification of conformational changes at the dimer interface by hydrogen-deuterium exchange confirmed by mutagenesis and structural reports provides a physical mechanism for active site communication in the half-sites regulation of SufS activity. Given the conservation of the interface interactions, this mechanism may be broadly applicable to type II cysteine desulfurase systems.

AB - As one of the most abundant elements on earth, sulfur is part of many small molecular metabolites and is key to their biological activities. Over the past few decades, some general strategies have been discovered for the incorporation of sulfur into natural products. In this review, we summarize recent efforts in elucidating the biosynthetic details for two sulfur-containing metabolites, ergothioneine and ovothiol. Their biosyntheses involve an unprecedented trans sulfur strategy, a combination of a mononuclear non-heme iron enzyme-catalyzed oxidative C-S bond formation reaction and a PLP enzyme-mediated C-S lyase reaction. PMID- 29589904 TI - Engineering a Dual Small Molecule Gated ZAP70 Switch in T Cells. AB - T cells expressing tumor-specific T cell receptors are promising cancer therapeutic agents, but safety control switches are needed to manage potential side effects arising from overactivity. Here, we present the first dual small molecule-gated ZAP70 signaling switch for the regulation of T cell activity. We show that when an analogue-sensitive ZAP70 allele is fused to the engineered ligand binding domain of the estrogen receptor, ERT2, its activity can be upregulated to an extent by a metabolite of an FDA-approved tamoxifen, 4-hydroxy tamoxifen, and downregulated by an ATP analogue, 3-MB-PP1. The strength of early T cell signaling can also be modulated by varying the concentrations of activator and inhibitor, and the switch exhibits temporal control on the time scale of minutes. Interestingly, the switch has the ability to control CD69 and calcium levels in T cells but has limited capabilities in the regulation of downstream cytokine release, suggesting further investigation is needed before it can be implemented in adoptive T cell therapy. PMID- 29589905 TI - Complex Chaperone Dependence of Rubisco Biogenesis. AB - Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), a ~530 kDa complex of 8 large (RbcL) and 8 small subunits (RbcS), mediates the fixation of atmospheric CO2 into usable sugars during photosynthesis. Despite its fundamental role, Rubisco is a remarkably inefficient enzyme and thus is produced by plants in huge amounts. It has long been a key target for bioengineering with the goal to increase crop yields. However, such efforts have been hampered by the complex requirement of Rubisco biogenesis for molecular chaperones. Recent studies have identified an array of auxiliary factors needed for the folding and assembly of the Rubisco subunits. The folding of plant RbcL subunits is mediated by the cylindrical chloroplast chaperonin, Cpn60, and its cofactor Cpn20. Folded RbcL requires a number of additional Rubisco specific assembly chaperones, including RbcX, Rubisco accumulation factors 1 (Raf1) and 2 (Raf2), and the Bundle sheath defective-2 (BSD2), to mediate the assembly of the RbcL8 intermediate complex. Incorporation of the RbcS and displacement of the assembly factors generates the active holoenzyme. An Escherichia coli strain expressing the chloroplast chaperonin and auxiliary factors now allows the expression of functional plant Rubisco, paving the way for Rubisco engineering by large scale mutagenesis. Here, we review our current understanding on how these chaperones cooperate to produce one of the most important enzymes in nature. PMID- 29589906 TI - Long-Range Capture and Delivery of Water-Dispersed Nano-objects by Microbubbles Generated on 3D Plasmonic Surfaces. AB - The possibility of investigating small amounts of molecules, moieties, or nano objects dispersed in solution constitutes a central step for various application areas in which high sensitivity is necessary. Here, we show that the rapid expansion of a water bubble can act as a fast-moving net for molecules or nano objects, collecting the floating objects in the surrounding medium in a range up to 100 MUm. Thanks to an engineered 3D patterning of the substrate, the collapse of the bubble could be guided toward a designed area of the surface with micrometric precision. Thus, a locally confined high density of particles is obtained, ready for evaluation by most optical/spectroscopic detection schemes. One of the main relevant strengths of the long-range capture and delivery method is the ability to increase, by a few orders of magnitude, the local density of particles with no changes in their physiological environment. The bubble is generated by an ultrafast IR laser pulse train focused on a resonant plasmonic antenna; due to the excitation process, the technique is trustworthy and applicable to biological samples. We have tested the reliabilities of the process by concentrating highly dispersed fluorescence molecules and fluorescent beads. Lastly, as an ultimate test, we have applied the bubble clustering method on nanosized exosome vesicles dispersed in water; due to the clustering effect, we were able to effectively perform Raman spectroscopy on specimens that were otherwise extremely difficult to measure. PMID- 29589907 TI - Structural Determinants for the Interactions of Chemically Modified Nucleic Acids with the Stabilin-2 Clearance Receptor. AB - The Stabilin receptors are systemic clearance receptors for some classes of chemically modified nucleic acid therapeutics. In this study, the recombinant human secreted ecto-domain of the small isoform of Stabilin-2 (s190) was purified from cell culture and evaluated for direct binding with a multitude of antisense oligonucleotides (ASOs) using a fluorescence polarization-based assay. The tested ASOs varied in their backbone composition, modification of the ribose 2' position, overall length of the oligo, and sequence of the nucleotide bases. A fully phosphorothioate (PS) ASO with a 5-10-5 pattern of flanking 2'- O methoxyethyl modifications was then used to test the effects of pH and salt concentration on receptor binding. These tests concluded that the PS backbone was the primary determinant for ASO binding and that decreasing pH and increasing salt generally increased the rate of ligand dissociation and fit within the biological parameters expected of a constitutive recycling receptor. These results will be useful in the rational design of therapeutic oligonucleotides for enhancing their affinity or avoidance of the Stabilin receptors. PMID- 29589908 TI - Sophisticated Construction of Binary PdPb Alloy Nanocubes as Robust Electrocatalysts toward Ethylene Glycol and Glycerol Oxidation. AB - The design of nanocatalysts by controlling pore size and particle characteristics is crucial to enhance the selectivity and activity of the catalysts. Thus, we have successfully demonstrated the synthesis of binary PdPb alloy nanocubes (PdPb NCs) by controlling pore size and particle characteristics. In addition, the as obtained binary PdPb NCs exhibited superior electrocatalytic activity of 4.06 A mg-1 and 16.8 mA cm-2 toward ethylene glycol oxidation reaction and 2.22 A mg-1 and 9.2 mA cm-2 toward glycerol oxidation reaction when compared to the commercial Pd/C. These astonishing characteristics are attributed to the attractive nanocube structures as well as the large number of exposed active areas. Furthermore, the bifunctional effects originated from Pd and Pb interactions help to display high endurance with less activity decay after 500 cycles, showing a great potential in fuel cell applications. PMID- 29589909 TI - Material-Independent Nanotransfer onto a Flexible Substrate Using Mechanical Interlocking Structure. AB - Nanowire-transfer technology has received much attention thanks to its capability to fabricate high-performance flexible nanodevices with high simplicity and throughput. However, it is still challenging to extend the conventional nanowire transfer method to the fabrication of a wide range of devices since a chemical adhesion-based nanowire-transfer mechanism is complex and time-consuming, hindering successful transfer of diverse nanowires made of various materials. Here, we introduce a material-independent mechanical-interlocking-based nanowire transfer (MINT) method, fabricating ultralong and fully aligned nanowires on a large flexible substrate (2.5 * 2 cm2) in a highly robust manner. For the material-independent nanotransfer, we developed a mechanics-based nanotransfer method, which employs a dry-removable amorphous carbon (a-C) sacrificial layer between a vacuum-deposited nanowire and the underlying master mold. The controlled etching of the sacrificial layer enables the formation of a mechanical interlocking structure under the nanowire, facilitating peeling off of the nanowire from the master mold robustly and reliably. Using the developed MINT method, we successfully fabricated various metallic and semiconductor nanowire arrays on flexible substrates. We further demonstrated that the developed method is well suited to the reliable fabrication of highly flexible and high performance nanoelectronic devices. As examples, a fully aligned gold (Au) microheater array exhibited high bending stability (106 cycling) and ultrafast (~220 ms) heating operation up to ~100 degrees C. An ultralong Au heater embedded cuprous-oxide (Cu2O) nanowire chemical gas sensor showed significantly improved reversible reaction kinetics toward NO2 with 10-fold enhancement in sensitivity at 100 degrees C. PMID- 29589910 TI - Single-Cell Digital Lysates Generated by Phase-Switch Microfluidic Device Reveal Transcriptome Perturbation of Cell Cycle. AB - With conventional gene expression profiling, information concerning cellular heterogeneity is often lost in the physical mixing and averaging of millions of cells. Single-cell transcriptome analysis has the potential to address these issues. However, there is a need to determine how many cells are needed to draw meaningful conclusions in each single-cell study. Here, we introduce the concept of "digital lysate" for assessing cellular heterogeneity with a phase-switch microfluidic platform and apply it to construct a molecular map of transcriptome perturbation during the cell cycle. Using a phase-switch droplet microfluidic platform and next-generation sequencing, we obtained transcriptomes of single cells by random sampling. Digital lysates were generated by permutating and averaging multiple single-cell transcriptomes. In our studied cell populations, digital lysates converged to physical lysates ( r = 0.93), and the sample-to sample repeatability was comparable to that of conventional analysis of a physical lysate ( r = 0.98). After determining the number of cells needed, single cell transcriptomes were used to organize cells into a map by molecular similarity, and the map was validated by cell cycle-specific markers ( p = 0.003). Cell cycle regulatory genes were inferred using this molecular map and verified with siRNA assays. The study described here provides an effective approach, the generation and analysis of digital lysates, to investigate cellular heterogeneity. PMID- 29589911 TI - MXene-Based Electrode with Enhanced Pseudocapacitance and Volumetric Capacity for Power-Type and Ultra-Long Life Lithium Storage. AB - Powerful yet thinner lithium-ion batteries (LIBs) are eagerly desired to meet the practical demands of electric vehicles and portable electronic devices. However, the use of soft carbon materials in current electrode design to improve the electrode conductivity and stability does not afford high volumetric capacity due to their low density and capacity for lithium storage. Herein, we report a strategy leveraging the MXene with superior conductivity and density to soft carbon as matrix and additive material for comprehensively enhancing the power capability, lifespan, and volumetric capacity of conversion-type anode. A kinetics favorable 2D nanohybrid with high conductivity, compact density, accumulated pseudocapacitance, and diffusion-controlled behavior is fabricated by coupling Ti3C2 MXene with high-density molybdenum carbide for fast lithium storage over 300 cycles with high capacities. By replacing the carbonaceous conductive agent with Ti3C2 MXene, the electrodes with better conductivity and dramatically reduced thickens could be further manufactured to achieve 37-40% improvement in capacity retention and ultra-long life of 5500 cycles with extremely slow capacity loss of 0.002% per cycle at high current rates. Ultrahigh volumetric capacity of 2460 mAh cm-3 could be attained by such MXene-based electrodes, highlighting the great promise of MXene in the development of high performance LIBs. PMID- 29589912 TI - beta-Cyclodextrin Reverses Binding of Perfluorooctanoic Acid to Human Serum Albumin. AB - Perfluorooctanoic acid (PFOA), a persistent organic pollutant known to cause adverse health effects, strongly binds to human serum albumin (HSA). beta Cyclodextrin (beta-CD), a nontoxic cyclic sugar, strongly complexes PFOA in a host-guest complex and has been proposed for environmental remediation of PFOA. The interactions between HSA, PFOA, and beta-CD were investigated in order to determine if beta-CD can reverse the binding of PFOA to HSA, with potential therapeutic applications toward exposure to PFOA. 19F Nuclear magnetic resonance (NMR), circular dichroism, and fluorescence spectroscopies were used to study these interactions. Multiple PFOA binding sites to HSA, one with strong affinity and others with low affinity, are evident from changes in the fluorescence emission spectra of HSA and the fluorescence lifetimes of the single Trp residue in HSA with increasing PFOA concentration. Structural changes in the protein are also evident from changes in the circular dichroism spectra of HSA upon titration of PFOA. Addition of beta-CD to PFOA and HSA reversed these changes, indicating that formation of the beta-CD:PFOA host-guest complex is favored even in the presence of HSA. Equimolar beta-CD to PFOA (1:1 beta-CD:PFOA ratio) causes dissociation of the weakly bound PFOA from HSA, whereas excess beta-CD relative to PFOA (5:1 beta-CD:PFOA ratio) leads to the complete disassociation of the strongly bound PFOA molecule from HSA. The 19F NMR studies further suggest that the 2:1 beta-CD:PFOA complex inhibits PFOA binding to HSA. These data demonstrate that beta-CD has potential to be used in therapeutic applications for PFOA in human blood.

AB - Telomere repeat binding factor 2 (TRF2) is critical for the protection of chromosome ends. Mounting evidence suggests that TRF2 associates with extratelomeric sites and TRF2 functions may not be limited to telomeres. Here, we show that the PCGF3 promoter harbors a sequence capable of forming the DNA secondary structure G-quadruplex motif, which is required for binding of TRF2 at the PCGF3 promoter. We demonstrate that promoter binding by TRF2 mediates PCGF3 promoter activity, and both the N-terminal and C-terminal domains of TRF2 are necessary for promoter activity. Altogether, this shows for the first time that a telomere binding factor may regulate a component of the polycomb group of proteins.

AB - Raman spectroscopy (RS) has shown promise as a tool to reveal biochemical changes that occur in cancer processes at the cellular level. However, when analyzing clinical samples, RS requires improvements to be able to resolve biological components from the spectra. We compared the strengths of Multivariate Curve Resolution (MCR) versus Principal Component Analysis (PCA) to deconvolve meaningful biological components formed by distinct mixtures of biological molecules from a set of mixed spectra. We exploited the flexibility of the MCR algorithm to easily accommodate different initial estimates and constraints. We demonstrate the ability of MCR to resolve undesired background signals from the RS that can be subtracted to obtain clearer cancer cell spectra. We used two triple negative breast cancer cell lines, MDA-MB 231 and MDA-MB 435, to illustrate the insights obtained by RS that infer the metabolic changes required for metastasis progression. Our results show that increased levels of amino acids and lower levels of mitochondrial signals are attributes of bone metastatic cells, whereas lung metastasis tropism is characterized by high lipid and mitochondria levels. Therefore, we propose a method based on the MCR algorithm to achieve unique biochemical insights into the molecular progression of cancer cells using RS.

AB - The ability to tailor the interfacial behaviors of nanoparticles (NPs) is crucial not only for the design of novel nanostructured materials with superior properties and of interest for many promising applications such as water purification, enhanced oil recovery, and innovative energy transduction, but also for a better insight into many biological systems where nanoscale particles such as proteins or viruses can interact and organize at certain interfaces. As a class of emerging building blocks, Janus NPs consisting of two compartments of different chemistry or polarity are ideal candidates to generate tunable and stable interfacial nanostructures because of the asymmetric nature. However, precise control over such interfacial nanostructures toward a controllable order and even responses to various external stimuli still remains a great challenge as the interfaces do not simply serve as a scaffold but rather induce complex enthalpic and entropic interactions. In this Account, we focus on our efforts on exploiting entropy strategies based on computational design to tailor the spatial distribution and ordering of NPs at the interfaces of various systems. First, we introduce the physical principle of entropic ordering, being the theoretical basis of entropy-directed interfacial self-assembly. The typical types of entropy, which have been harnessed to manipulate the interfacial NP organization, are then summarized, including conformational entropy, shape entropy, and rotational and vibrational entropy. Next, we describe the emerging pathways in the development of novel environmentally responsive systems which involve the use of entropy to access the stimuli-responsive behaviors of interfacial nanostructures. Taking one step further, how molecular architectures can be tailored to tune the entropic contributions to the interfacial self-assembly is demonstrated, through identifying the effects of various intrinsic properties of block segments, such as chain length and stiffness, on entropy-governed precise organization of Janus NPs at block copolymer interfaces. Finally, we detail some key factors for tailoring interfacial organization through entropy. In summary, entropy strategies offer a promising and abundant framework for precisely programming the structural organization of NPs at interfaces. We discuss future directions to signify the framework in tailoring the interfacial organization of NPs. We hope that this Account will promote further efforts toward fundamental research and the wide applications of designed interfacial assemblies in new types of functional nanomaterials and beyond.

AB - The ab initio rational structure-based design of a synthetic molecular receptor for a given complex biomolecular guest remains an elusive objective, yet remarkable progress has been achieved in recent years. This Account deals with the use of folded artificial aromatic amide oligomers, also termed aromatic foldamers, inspired from biopolymer structures, for the design of helical molecular capsules that can recognize guest molecules, completely surround them, and isolate them from the solvent, thus giving rise to a sort of guest encapsulation associated with slow binding and release kinetics. The development of new amino acid, diacid, and diamine monomers, a main source of creativity in this field, progress in their assembly into ever longer oligoamide sequences, and the predictability of the folded structures due to their inherent rigidity and simple folding principles, allowed for the design and preparation of unimolecular and bimolecular capsule shapes. These capsules consist of molecular helices having a large diameter in the middle and a narrow diameter at both ends thus creating a cavity suitable for binding a guest molecule. The understanding of molecular recognition properties within these bioinspired containers has greatly progressed. Recognition of simple guests such as diols or amino-alcohols may thus be predicted, and hosts can be proposed for guests as complex as saccharides using first principle design. Taking advantage of the modular nature of oligomeric sequences, of their synthetic accessibility and of their propensity to grow into crystals suitable for X-ray crystallographic analysis, a structure based iterative design methodology has been developed that eventually yielded exquisite guest selectivity, affinity, and diastereoselectivity. This methodology involves rational negative design steps during which changes in the foldamer capsule sequence are not intended to improve binding to the targeted guest but instead to exclude the binding of other guests while preserving key interactions with the target. Metal ions can also be introduced at the inner rim of foldamer capsules and eventually assist the binding of an organic guest. These results demonstrate the viability of an ab initio approach to abiotic receptor design based on aromatic foldamers. The dynamic of the capsules associated with their self-organized nature provides opportunities to not only tune guest binding and selectivity, but also guest capture and release kinetics as well as cavity size and shape. Controlled release thus emerges as a realistic objective. Recent progress thus opens up multiple perspectives for the development of tailored hosts, sensors, and carriers structurally and conceptually different from earlier generations of macrocyclic-based receptors or from supramolecular containers produced by self-assembly.

AB - The iron-catalyzed highly Markovnikov-type selective and enantioselective hydrosilylation of terminal aliphatic alkenes with good functional group tolerance is developed. This operationally simple protocol uses earth-abundant transition metal catalyst, readily available aliphatic alkenes and hydrosilanes to construct valuable chiral organosilanes with better than 99% ee in most cases.

PMID- 29589918 TI - Effects of Hydrophilic Residues and Hydrophobic Length on Flip-Flop Promotion by Transmembrane Peptides. AB - Peptide-induced phospholipid flip-flop (scrambling) was evaluated using transmembrane model peptides in which the central residue was substituted with various amino acid residues (sequence: Ac-GKK(LA) nXW(LA) nLKKA-CONH2). Peptides with a strongly hydrophilic residue (X = Q, N, or H) had higher scramblase activity than that of other peptides, and the activity was also dependent on the length of the peptides. Peptides with a hydrophobic stretch of 17 residues showed high flip-promotion propensity, whereas those of 21 and 25 residues did not, suggesting that membrane thinning under negative mismatch conditions promotes the flipping. Interestingly, a hydrophobic stretch of 19 residues intensively promoted phospholipid scrambling and membrane leakage. The distinctive characteristics of the peptide were ascribed by long-term molecular dynamics simulation to the arrangement of central glutamine and terminal four lysine residues on the same side of the helix. The combination of simulated and experimental data enables understanding of the mechanisms by which transmembrane helices, and ultimately unidentified scramblases in biomembranes, cause lipid scrambling.

AB - Rate and mechanistic studies of ortholithiations by lithium 2,2,6,6 tetramethylpiperidide focus on four arenes: 1,4-bis(trifluoromethyl)benzene, 1,3 bis(trifluoromethyl)benzene, 1,3-dimethoxybenzene, and 4,4-dimethyl-2-phenyl-2 oxazoline. Metalations occur via substrate-dependent combinations of monosolvated monomer, disolvated monomer, and tetrasolvated dimer (triple ions). Density functional theory computational studies augment the experimental data. We discuss the challenges presented by shifting dimer-monomer proportions in determining the observable reaction orders and our mathematical treatment of such shifting in reactant structure. PMID- 29589921 TI - A Thermodynamic Model for Redox-Dependent Binding of Carbon Monoxide at Site Differentiated, High Spin Iron Clusters. AB - Binding of N2 and CO by the FeMo-cofactor of nitrogenase depends on the redox level of the cluster, but the extent to which pure redox chemistry perturbs the affinity of high spin iron clusters for pi-acids is not well understood. Here, we report a series of site-differentiated iron clusters that reversibly bind CO in redox states FeII4 through FeIIFeIII3. One electron redox events result in small changes in the affinity for (at most ~400-fold) and activation of CO (at most 28 cm-1 for nuCO). The small influence of redox chemistry on the affinity of these high spin, valence-localized clusters for CO is in stark contrast to the large enhancements (105-1022 fold) in pi-acid affinity reported for monometallic and low spin, bimetallic iron complexes, where redox chemistry occurs exclusively at the ligand binding site. While electron-loading at metal centers remote from the substrate binding site has minimal influence on the CO binding energetics (~1 kcal.mol-1), it provides a conduit for CO binding at an FeIII center. Indeed, internal electron transfer from these remote sites accommodates binding of CO at an FeIII, with a small energetic penalty arising from redox reorganization (~2.6 kcal.mol-1). The ease with which these clusters redistribute electrons in response to ligand binding highlights a potential pathway for coordination of N2 and CO by FeMoco, which may occur on an oxidized edge of the cofactor. PMID- 29589922 TI - Mutagenesis of an Active-Site Loop in Tryptophan Hydroxylase Dramatically Slows the Formation of an Early Intermediate in Catalysis. AB - Solution studies of the aromatic amino acid hydroxylases are consistent with the FeIVO intermediate not forming until both the amino acid and tetrahydropterin substrates have bound. Structural studies have shown that the positions of active site loops differs significantly between the free enzyme and the enzyme-amino acid-tetrahydropterin complex. In tryptophan hydroxylase (TrpH) these mobile loops contain residues 124-134 and 365-371, with a key interaction involving Ile366. The I366N mutation in TrpH results in decreases of 1-2 orders of magnitude in the kcat and kcat/ Km values. Single turnover analyses establish that the limiting rate constant for turnover is product release for the wild-type enzyme but is formation of the first detectable intermediate I in catalysis in the mutant enzyme. The mutation does not alter the kinetics of NO binding to the ternary complex nor does it uncouple FeIVO formation from amino acid hydroxylation. The effects on the kcat value of wild-type TrpH of changing viscosity are consistent with rate-limiting product release. While the effect of viscosity on the kcat/ KO2 value is small, consistent with reversible oxygen binding, the effects on the kcat/ Km values for tryptophan and the tetrahydropterin are large, with the latter value exceeding the expected limit and varying with the identity of the viscogen. In contrast, the kinetic parameters of I366N TrpH show small changes with viscosity. The results are consistent with binding of the amino acid and pterin substrate to form the ternary complex being directly coupled to closure of loops over the active site and formation of the reactive complex. The mutation destabilizes this initial event. PMID- 29589923 TI - Surprisingly Flexible Oxonium/Borohydride Ion Pair Configurations. AB - We investigate the geometry of oxonium/borohydride ion pairs [ether-H(+) ether][LA-H(-)] with dioxane, THF, and Et2O as ethers and B(C6F5)3 as the Lewis acid (LA). The question is about possible location of the disolvated proton, [ether-H(+)-ether], with respect to the hydride of the structurally complex [LA H(-)] anion. Using Born-Oppenheimer molecular dynamics and a comparison of the potential and free energies of the optimized configurations, we show that herein considered ion pairs are much more flexible geometrically than previously thought. Conformers with different locations of cations with respect to anions are governed by a flat energy-landscape. We found a novel configuration in which oxonium is below [LA-H(-)], with respect to the direction of borane -> hydride vector, and the proton-hydride distance is ca. 6 A. With calculations of the vibrational spectra of [ether-H(+)-ether][(C6F5)3B-H(-)] for dioxane, THF, and Et2O as ethers, we investigate the manifestation of SSLB-type (short, strong, low barrier) hydrogen bonding in the OHO motif of an oxonium cation. PMID- 29589924 TI - A Cannibalistic Approach to Grand Canonical Crystal Growth. AB - Canonical molecular dynamics simulations of crystal growth from solution suffer from severe finite-size effects. As the crystal grows, the solute molecules are drawn from the solution to the crystal, leading to a continuous drop in the solution concentration. This is in contrast to experiments in which the crystal grows at an approximately constant supersaturation of a bulk solution. Recently, Perego et al. [ J. Chem. Phys. 2015, 142, 144113] showed that in a periodic setup in which the crystal is represented as a slab, the concentration in the vicinity of the two surfaces can be kept constant while the molecules are drawn from a part of the solution that acts as a molecular reservoir. This method is quite effective in studying crystallization under controlled supersaturation conditions. However, once the reservoir is depleted, the constant supersaturation conditions cannot be maintained. We propose a variant of this method to tackle this depletion problem by simultaneously dissolving one side of the crystal while letting the other side grow. A continuous supply of particles to the solution due to the crystal dissolution maintains a steady solution concentration and avoids reservoir depletion. In this way, a constant supersaturation condition can be maintained for as long as necessary. We have applied this method to study the growth and dissolution of urea crystal from water solution under constant supersaturation and undersaturation conditions, respectively. The computed growth and dissolution rates are in good agreement with those obtained in previous studies. PMID- 29589925 TI - Systems Analysis of Physical Absorption of CO2 in Ionic Liquids for Pre Combustion Carbon Capture. AB - This study develops an integrated technical and economic modeling framework to investigate the feasibility of ionic liquids (ILs) for precombustion carbon capture. The IL 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide is modeled as a potential physical solvent for CO2 capture at integrated gasification combined cycle (IGCC) power plants. The analysis reveals that the energy penalty of the IL-based capture system comes mainly from the process and product streams compression and solvent pumping, while the major capital cost components are the compressors and absorbers. On the basis of the plant-level analysis, the cost of CO2 avoided by the IL-based capture and storage system is estimated to be $63 per tonne of CO2. Technical and economic comparisons between IL- and Selexol-based capture systems at the plant level show that an IL-based system could be a feasible option for CO2 capture. Improving the CO2 solubility of ILs can simplify the capture process configuration and lower the process energy and cost penalties to further enhance the viability of this technology. PMID- 29589927 TI - Development of the Fragment Molecular Orbital Method for Calculating Nonlocal Excitations in Large Molecular Systems. AB - We developed the fragment-based method for calculating nonlocal excitations in large molecular systems. This method is based on the multilayer fragment molecular orbital method and the configuration interaction single (CIS) wave function using localized molecular orbitals. The excited-state wave function for the whole system is described as a superposition of configuration state functions (CSFs) for intrafragment excitations and for interfragment charge-transfer excitations. The formulation and calculations of singlet excited-state Hamiltonian matrix elements in the fragment CSFs are presented in detail. The efficient approximation schemes for calculating the matrix elements are also presented. The computational efficiency and the accuracy were evaluated using the molecular dimers and molecular aggregates. We confirmed that absolute errors of 50 meV (relative to the conventional calculations) are achievable for the molecular systems in their equilibrium geometries. The perturbative electron correlation correction to the CIS excitation energies is also demonstrated. The present theory can compute a large number of excited states in large molecular systems; in addition, it allows for the systematic derivation of a model exciton Hamiltonian. These features are useful for studying excited-state dynamics in condensed molecular systems based on the ab initio electronic structure theory.

AB - Solving and predicting atomic structures from first-principles methodologies is limited by the computational cost of exploring the search space, even when relatively inexpensive density functionals are used. Here, we present an efficient approach where the search is performed using density functional tight binding, with an automatic adaptive parametrization scheme for the repulsive pair potentials. We successfully apply the method to the genetic algorithm optimization of bulk carbon, titanium dioxide, palladium oxide, and calcium hydroxide, and we assess the stability of the unknown crystal structure of palladium hydroxide. PMID- 29589926 TI - Designing Well-Structured Cyclic Pentapeptides Based on Sequence-Structure Relationships. AB - Cyclic peptides are a promising class of molecules for unique applications. Unfortunately, cyclic peptide design is severely limited by the difficulty in predicting the conformations they will adopt in solution. In this work, we use explicit-solvent molecular dynamics simulations to design well-structured cyclic peptides by studying their sequence-structure relationships. Critical to our approach is an enhanced sampling method that exploits the essential transitional motions of cyclic peptides to efficiently sample their conformational space. We simulated a range of cyclic pentapeptides from all-glycine to a library of cyclo (X1X2AAA) peptides to map their conformational space and determine cooperative effects of neighboring residues. By combining the results from all cyclo (X1X2AAA) peptides, we developed a scoring function to predict the structural preferences for X1-X2 residues within cyclic pentapeptides. Using this scoring function, we designed a cyclic pentapeptide, cyclo-(GNSRV), predicted to be well structured in aqueous solution. Subsequent circular dichroism and NMR spectroscopy revealed that this cyclic pentapeptide is indeed well structured in water, with a nuclear Overhauser effect and J-coupling values consistent with the predicted structure.

AB - The nucleosome core particle (NCP), comprised of histone proteins wrapped with ~146 base pairs of DNA, provides both protection and controlled access to DNA so as to regulate vital cellular processes. High-resolution structures of nucleosomes and nucleosome complexes have afforded a clear understanding of the structural role of NCPs, but a detailed description of the dynamical properties that facilitate DNA-templated processes is only beginning to emerge. Using methyl TROSY NMR approaches we evaluate the effect of point mutations designed to perturb key histone interfaces that become destabilized during nucleosome remodeling in an effort to probe NCP plasticity. Notably the NCP retains its overall structural integrity, yet relaxation experiments of mutant nucleosomes reveal significant dynamics within a central histone interface associated with alternative NCP conformations populated to as much as 15% under low salt conditions. This work highlights the inherent plasticity of NCPs and establishes methyl-TROSY NMR as a valuable compliment to current single molecule methods in quantifying NCP dynamic properties. PMID- 29589930 TI - Preparation and Characterization of a Small Library of Thermally-Labile End-Caps for Variable-Temperature Triggering of Self-Immolative Polymers. AB - The reaction between furans and maleimides has increasingly become a method of interest as its reversibility makes it a useful tool for applications ranging from self-healing materials, to self-immolative polymers, to hydrogels for cell culture and for the preparation of bone repair. However, most of these applications have relied on simple monosubstituted furans and simple maleimides and have not extensively evaluated the potential thermal variability inherent in the process that is achievable through simple substrate modification. A small library of cycloadducts suitable for the above applications was prepared, and the temperature dependence of the retro-Diels-Alder processes was determined through in situ 1H NMR analyses complemented by computational calculations. The practical range of the reported systems ranges from 40 to >110 degrees C. The cycloreversion reactions are more complex than would be expected based on simple trends expected based on frontier molecular orbital analyses of the materials.

AB - For the complete structure elucidation of an endogenous sperm-activating and attracting factor isolated from eggs of the ascidian Ascidia sydneiensis ( Assydn SAAF), its two possible diastereomers with respect to C-25 were synthesized. Starting from ergosterol, the characteristic steroid backbone was constructed by using an intramolecular pinacol coupling reaction and stereoselective reduction of a hydroxy ketone as key steps, and the side chain was introduced by Julia Kocienski olefination. Comparison of the NMR data of the two diastereomers with those of the natural product led to the elucidation of the absolute configuration as 25 S; thus the complete structure was determined and the first synthesis of Assydn-SAAF was achieved.

AB - Malaria is still one of the most prevalent parasitic infections in the world, with half of the world's population at risk for malaria. The effectiveness of current antimalarial therapies, even that of the most recent class of antimalarial drugs (artemisinin-combination therapies, ACTs), is under continuous threat by the spread of resistant Plasmodium strains. As a consequence, there is still an urgent requirement for new antimalarial drugs. We previously reported the identification of 4(1 H)-pyridones as a novel series with potent antimalarial activities. The low solubility was identified as an issue to address. In this paper, we describe the synthesis and biological evaluation of 4(1 H)-pyridones with potent antimalarial activities in vitro and in vivo and improved pharmacokinetic profiles. Their main structural novelties are the presence of polar moieties, such as hydroxyl groups, and the replacement of the lipophilic phenyl rings with pyridines on their lipophilic side chains.

AB - The most critical problem regarding the use of reverse micelles (RMs) in several fields is the toxicity of their partial components. In this sense, many efforts have been made to characterize nontoxic RM formulations on the basis of biological amphiphiles and/or different oils. In this contribution, the microstructure of biocompatible mixed RMs formulated by sodium 1,4-bis-2 ethylhexylsulfosuccinate (AOT) and tri- n-octylphosphine oxide (TOPO) surfactants dispersed in the friendly solvent methyl laurate was studied by using SAXS and 31P NMR and by following the solvatochromic behavior of the molecular probe 4 aminophthalimide (4-AP). The results indicated the presence of RM aggregates upon TOPO incorporation with a droplet size reduction and an increase in the interfacial fluidity in comparison with pure AOT RMs. When confined inside the mixed systems, 4-AP showed a red-edge excitation shift and confirmed the increment of interfacial fluidity upon TOPO addition. Also, the partition between the external nonpolar solvent and the RM interface and an increase in both the local micropolarity and the capability to form a hydrogen bond interaction between 4-AP and a mixed interface were observed. The findings have been explained in terms of the nonionic surfactant structure and its complexing nature expressed at the interfacial level. Notably, we show how two different approaches, i.e., SAXS and the solvatochromism of the probe 4-AP, can be used in a complementary way to enhance our understanding of the interfacial fluidity of RMs, a parameter that is difficult to measure directly.

AB - Lipophilic efficiency (LipE) is an important metric that has been increasingly applied in drug discovery medicinal chemistry lead optimization programs. In this Perspective, using literature drug discovery examples, we discuss the concept of rigorously applying LipE to guide medicinal chemistry lead optimization toward drug candidates with potential for superior in vivo efficacy and safety, especially when guided by physiochemical property-based optimization (PPBO). Also highlighted are examples of small structural modifications such as addition of single atoms, small functional groups, and cyclization that produce large increases in LipE. Understanding the factors that may contribute to LipE changes through analysis of ligand-protein crystal structures and using structure-based drug design (SBDD) to increase LipE by design is also discussed. Herein we advocate for use of LipE analysis coupled with PPBO and SBDD as an efficient mechanism for drug design.

PMID- 29589938 TI - Rapid Trace Detection and Isomer Quantitation of Pesticide Residues via Matrix Assisted Laser Desorption/Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry. AB - Matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR-MS) has been applied for rapid, sensitive, undisputed, and quantitative detection of pesticide residues on fresh leaves with little sample pretreatment. Various pesticides (insecticides, bactericides, herbicides, and acaricides) are detected directly in the complex matrix with excellent limits of detection down to 4 MUg/L. FTICR-MS could unambiguously identify pesticides with tiny mass differences (~0.017 75 Da), thereby avoiding false-positive results. Remarkably, pesticide isomers can be totally discriminated by use of diagnostic fragments, and quantitative analysis of pesticide isomers is demonstrated. The present results expand the horizons of the MALDI-FTICR-MS platform in the reliable determination of pesticides, with integrated advantages of ultrahigh mass resolution and accuracy. This method provides growing evidence for the resultant detrimental effects of pesticides, expediting the identification and evaluation of innovative pesticides. PMID- 29589937 TI - Rheology of Membrane-Attached Minimal Actin Cortices. AB - The actin cortex is a thin cross-linked network attached to the plasma membrane, which is responsible for the cell's shape during migration, division, and growth. In a reductionist approach, we created a minimal actin cortex (MAC) attached to a lipid membrane to correlate the filamentous actin architecture with its viscoelastic properties. The system is composed of a supported 1-palmitoyl-2 oleoyl- sn-glycero-3-phosphocholine bilayer doped with the receptor lipid phosphatidylinositol(4,5)-bisphosphate (PtdIns(4,5)P2) to which a constitutively active mutant of ezrin, which is a direct membrane-cytoskeleton linker, is bound. The formation of the MAC on the supported lipid bilayer is analyzed as a function of increasing PtdIns(4,5)P2/ezrin pinning points, revealing an increase in the intersections between actin filaments, that is, the node density of the MAC. Bead tracking microrheology on the membrane-attached actin network provides information about its viscoelastic properties. The results show that ezrin serves as a dynamic cross-linker for the actin cortex attached to the lipid bilayer and that the stiffness of the network is influenced by the pinning point density, relating the plateau storage modulus G0 to the node density of the MAC.

AB - Water is crucial to plant growth and development because it serves as a medium for all cellular functions. Thus, the improvement of plant drought tolerance or water use efficiency/water uptake efficiency is important in modern agriculture. In this review, we mainly focus on new genetic factors for ameliorating drought tolerance or water use efficiency/water uptake efficiency of plants and explore the involvement of these genetic factors in the regulation of improving plant drought tolerance or water use efficiency/water uptake efficiency, which is a result of altered stomata density and improving root systems (primary root length, hair root growth, and lateral root number) and enhanced production of osmotic protectants, which is caused by transcription factors, proteinases, and phosphatases and protein kinases. These results will help guide the synthesis of a model for predicting how the signals of genetic and environmental stress are integrated at a few genetic determinants to control the establishment of either water use efficiency or water uptake efficiency. Collectively, these insights into the molecular mechanism underpinning the control of plant drought tolerance or water use efficiency/water uptake efficiency may aid future breeding or design strategies to increase crop yield. PMID- 29589940 TI - Simultaneous Improvement of Antimicrobial, Antifouling, and Transport Properties of Forward Osmosis Membranes with Immobilized Highly-Compatible Polyrhodanine Nanoparticles. AB - This work shows that incorporating highly compatible polyrhodanine nanoparticles (PRh-NPs) into a polyamide (PA) active layer allows for fabricating forward osmosis (FO) thin-film composite (TFC)-PRh membranes that have simultaneously improved antimicrobial, antifouling, and transport properties. To the best of our knowledge, this is the first reported study of its kind to this date. The presence of the PRh-NPs on the surface of the TFC-PRh membranes active layers is evaluated using FT-IR spectroscopy, SEM, and XPS. The microscopic interactions and their impact on the compatibility of the PRh-NPs with the PA chains were studied using molecular dynamics simulations. When tested in forward osmosis, the TFC-PRh-0.01 membrane (with 0.01 wt % PRh) shows significantly improved permeability and selectivity because of the small size and the high compatibility of the PRh-NPs with PA chains. For example, the TFC-PRh-0.01 membrane exhibits a FO water flux of 41 l/(m2.h), higher than a water flux of 34 l/(m2.h) for the pristine TFC membrane, when 1.5 molar NaCl was used as draw solution in the active-layer feed-solution mode. Moreover, the reverse solute flux of the TFC-PRh 0.01 membrane decreases to about 115 mmol/(m2.h) representing a 52% improvement in the reverse solute flux of this membrane in comparison to the pristine TFC membrane. The surfaces of the TFC-PRh membranes were found to be smoother and more hydrophilic than those of the pristine TFC membrane, providing improved antifouling properties confirmed by a flux decline of about 38% for the TFC-PRh 0.01 membranes against a flux decline of about 50% for the pristine TFC membrane when evaluated with a sodium alginate solution. The antimicrobial traits of the TFC-PRh-0.01 membrane evaluated using colony-forming units and fluorescence imaging indicate that the PRh-NPs hinder cell deposition on the TFC-PRh-0.01 membrane surface effectively, limiting biofilm formation.

In addition, an unknown diastereomer was synthesized. PMID- 29589942 TI - Pyridinium Analogues of Green Fluorescent Protein Chromophore: Fluorogenic Dyes with Large Solvent-Dependent Stokes Shift. AB - Novel fluorogenic dyes based on the GFP chromophore are developed. The compounds contain a pyridinium ring instead of phenolate and feature large Stokes shifts and solvent-dependent variations in the fluorescence quantum yield. Electronic structure calculations explain the trends in solvatochromic behavior in terms of the increase of the dipole moment upon excited-state relaxation in polar solvents associated with the changes in bonding pattern in the excited state. A unique combination of such optical characteristics and lipophilic properties enables using one of the new dyes for imaging the membrane structure of endoplasmic reticulum. An extremely high photostability (due to a dynamic exchange between the free and absorbed states) and selectivity make this compound a promising label for this type of cellular organelles.

AB - A simplified approach to quantum yield ([Formula: see text]) measurement using in situ LED NMR spectroscopy has been developed. The utility and performance of NMR actinometry has been demonstrated for the well-known chemical actinometers potassium ferrioxalate and o-nitrobenzaldehyde. A novel NMR-friendly actinometer, 2,4-dinitrobenzaldehyde, has been introduced for both 365 and 440 nm wavelengths. The method has been utilized successfully to measure the quantum yield of several recently published photochemical reactions.

Through a series of biochemical analyses, Pip is biosynthesized through a two-step cascade reaction. Three intermediates possibly exist simultaneously as an equilibrium matter in the first-step reaction catalyzed by HsAld1, while HsSard4 performs as a ketimine reductase and chemoselectively and stereoselectively takes 1,2-dehydropipecolic acid as the preferred substrate in vitro. PMID- 29589945 TI - Slippery Liquid-Infused Porous Surfaces (SLIPS) Using Layer-by-Layer Polyelectrolyte Assembly in Organic Solvent. AB - Slippery liquid-infused porous surfaces (SLIPS) have potential impact on a wide range of industries, including healthcare, food packaging, and automobile. A tremendouseffort has been focused on developing novel fabrication methods for making SLIPS. However, current fabrication methods usually involve harsh conditions and complicated postfabrication modifications or are limited to specific substrates. Presented here is a novel method for the fast and facile fabrication of SLIPS. Layer-by-layer (LBL) assembly of branched polyethylenimine and Nafion, a perfluorinated polyelectrolyte, is performed with methanol as the solvent. Hierarchically rough and superhydrophobic surface is obtained directly without further modification on various substrates. The surface properties are shown to highly depend on the LBL assembly parameters, including deposition cycles, dipping time, rinsing time, and drying time between baths. The polyelectrolyte multilayers obtained with this method are infused with Krytox 100 to form SLIPS surfaces, which show excellent omniphobic, antifouling, self cleaning, flexible, and optical properties. The result of this study not only simplifies the fabrication of SLIPS surfaces, but also provides great insight for making LBL films with specific morphologies.

AB - A new copper-catalyzed enantioselective aza-Freidel-Crafts reaction between phenols and N-sulfonyl aldimines that provides chiral secondary benzylamines in good to excellent yields and excellent enantioselectivities (up to 99% ee) is disclosed. In particular, excellent scope with alkylimines was observed for the first time.

AB - Oxyallyl cations are prepared in situ from readily available alpha-tosyloxy ketones and act as transient electrophilic partners in (3 + 3) cycloaddition with nitrones. Under mild conditions, this method provides a chemoselective and diastereoselective route to polysubstituted 1,2-oxazinanes. A stepwise process is proposed to rationalize the diastereoselectivity of this transformation. PMID- 29589949 TI - Strain-Driven Stacking Faults in CdSe/CdS Core/Shell Nanorods. AB - Colloidal semiconductor nanocrystals are commonly grown with a shell of a second semiconductor material to obtain desired physical properties, such as increased photoluminescence quantum yield. However, the growth of a lattice-mismatched shell results in strain within the nanocrystal, and this strain has the potential to produce crystalline defects. Here, we study CdSe/CdS core/shell nanorods as a model system to investigate the influence of core size and shape on the formation of stacking faults in the nanocrystal. Using a combination of high-angle annular dark-field scanning transmission electron microscopy and pair-distribution function analysis of synchrotron X-ray scattering, we show that growth of the CdS shell on smaller, spherical CdSe cores results in relatively small strain and few stacking faults. By contrast, growth of the shell on larger, prolate spheroidal cores leads to significant strain in the CdS lattice, resulting in a high density of stacking faults. PMID- 29589950 TI - Dual-Frequency Comb Transient Absorption: Broad Dynamic Range Measurement of Femtosecond to Nanosecond Relaxation Processes. AB - We experimentally demonstrate a dual-frequency comb-based transient absorption (DFC-TA) technique, which has a 12 fs time resolution and an ultrafast scan rate. Here, the fast scan rate is achieved by employing asynchronous optical sampling (ASOPS), which utilizes two independent mode-locked lasers with a slightly detuned repetition rates. The ASOPS approach is advantageous because photodegradation damage of optical sample during TA measurements can be minimized by a gated sampling. We show that the vibrational and electronic population relaxations of near-IR dye molecules in solution that occur in the time range from femtoseconds to nanoseconds can be resolved even with a single time scan measurement. The phase coherent nature of our dual-frequency comb lasers is shown to be the key for successful coherent averaging with femtosecond time resolution preserved over many data acquisitions. We anticipate that the present DFC-TA method without using any pump-probe time delay devices could be of use in developing ultrafast TA-based microscopy and time-resolved coherent multidimensional spectroscopy. PMID- 29589951 TI - Optical Imaging and Spectroscopic Characterization of Self-Assembled Environmental Adsorbates on Graphene. AB - Topographic studies using scanning probes have found that graphene surfaces are often covered by micron-scale domains of periodic stripes with a 4 nm pitch. These stripes have been variously interpreted as structural ripples or as self assembled adsorbates. We show that the stripe domains are optically anisotropic by imaging them using a polarization-contrast technique. Optical spectra between 1.1 and 2.8 eV reveal that the anisotropy in the in-plane dielectric function is predominantly real, reaching 0.6 for an assumed layer thickness of 0.3 nm. The spectra are incompatible with a rippled graphene sheet but would be quantitatively explained by the self-assembly of chainlike organic molecules into nanoscale stripes. PMID- 29589953 TI - Ten-Year Results of Medial Open-Wedge High Tibial Osteotomy and Chondral Resurfacing in Severe Medial Osteoarthritis and Varus Malalignment. AB - BACKGROUND: High tibial osteotomy (HTO) is a widely used treatment option for medial osteoarthritis and varus malalignment, especially in young patients with early osteoarthritis. Limited outcome data are available for this procedure in severe osteoarthritis, and no long-term data are available using newer implants. PURPOSE: To determine survivorship and functional results of medial open-wedge HTO combined with a chondral resurfacing (CR) procedure (abrasion plus microfracture) in severe medial osteoarthritis (Kellgren-Lawrence grade 3 and 4) and varus malalignment. Furthermore, factors that potentially influence the outcome were analyzed. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: From September 2005 to December 2008, all cases of HTO (fixation with an angular stable internal fixator) combined with CR were prospectively surveyed with regard to survival (Kaplan-Meier-method, not requiring arthroplasty) and functional outcome (subjective International Knee Documentation Committee [IKDC] score). Cartilage regeneration at the time of hardware removal, tibial bone varus angle (TBVA), pre- and postoperative mechanical medial proximal tibial angle (MPTA), and postoperative alignment were analyzed with regard to the result. RESULTS: Seventy-nine knees were included (73 patients; mean age 50.9 +/- 7.6 years). The follow-up rate was 90% at 10.0 +/- 1.2 years (range, 8.3-12.1 years). Pre- and postoperative mechanical tibiofemoral axis were 9.6 degrees +/- 3.0 degrees of varus and 0.6 degrees +/- 2.7 degrees of valgus, respectively. Survival rate was 81.7% (95% CI, 72.5%-90.9%) at 10 years. Subjective IKDC score significantly improved from 44 +/- 11 preoperatively to 70 +/- 13 at one, 66 +/- 15 at three, 66 +/- 15 at five, and 65 +/- 17 at ten years ( P < .001 at any point of follow up). Poor cartilage regeneration and low preoperative IKDC score (<40) were associated with decreased survival. High preoperative TBVA was associated with better and an overcorrected MPTA (>95 degrees ) with inferior functional outcome at final follow-up, respectively. CONCLUSION: Even in cases of severe medial osteoarthritis and varus malalignment, HTO in combination with a CR procedure is a good to excellent treatment option. The role of the CR procedure remains unclear. Although good results are obtained with overcorrected MPTA, long-term functional outcome is inferior. PMID- 29589952 TI - Direct Mapping of Phase Separation across the Metal-Insulator Transition of NdNiO3. AB - Perovskite rare-earth nickelates RNiO3 are prototype correlated oxides displaying a metal-insulator transition (MIT) at a temperature tunable by the ionic radius of the rare-earth R. Although its precise origin remains a debated topic, the MIT can be exploited in various types of applications, notably for resistive switching and neuromorphic computation. So far, the MIT has been mostly studied by macroscopic techniques, and insights into its nanoscale mechanisms were only provided recently by X-ray photoemission electron microscopy through absorption line shifts, used as an indirect proxy to the resistive state. Here, we directly image the local resistance of NdNiO3 thin films across their first-order MIT using conductive-atomic force microscopy. Our resistance maps reveal the nucleation of ~100-300 nm metallic domains in the insulating state that grow and percolate as temperature increases. We discuss the resistance contrast mechanism, analyze the microscopy and transport data within a percolation model, and propose experiments to harness this mesoscopic electronic texture in devices. PMID- 29589954 TI - Validation of an MRI Protocol for Routine Quantitative Assessment of Tunnel Position in Anterior Cruciate Ligament Reconstruction. AB - BACKGROUND: No standardized methodology and objective criteria currently exist to accurately and objectively assess tunnel placement and consequent graft orientation in anterior cruciate ligament (ACL) reconstruction (ACLR) through a single imaging modality. Advances in magnetic resonance imaging (MRI) technology have enabled the use of volumetric high spatial and contrast resolution proton density-weighted sequencing, which allows precise delineation of graft orientation, tunnel position, and quantitative assessment of tunnel position relationship to adjacent reproducible anatomic landmarks. PURPOSE: To establish an MRI protocol that would provide an accurate alternative to 3-dimensional computed tomography (3D-CT) for standardized assessment of bone tunnel placement in ACLR, as a component of assessing ACLR outcomes and to assist in presurgical planning for revision ACLR. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: Twenty-four participants diagnosed with a failed ACLR underwent MRI and 3D-CT per the imaging protocols of the Sydney Orthopaedic Research Institute, in which the acquired data were converted to 3D models. The bone tunnels of the previous ACLR were then intraoperatively digitized at the tunnel aperture and along the length of the tunnel (barrel) and used as the reference standard to evaluate the accuracy of high-resolution MRI and 3D-CT. Differences in geometry between the image-based model and the reference point cloud were calculated through point-to-point comparison. RESULTS: At the tunnel apertures, no significant differences were detected between the MRI and 3D-CT models versus the reference models for the femur ( P = .9472) and tibia ( P = .5779). Mean +/- SD tunnel barrel deviations between MRI and 3D-CT were 0.48 +/- 0.28 mm (femur) and 0.46 +/- 0.27 mm (tibia). No significant differences were detected between the MRI and 3D-CT models versus the reference models for the femoral ( P = .5730) and tibial ( P = .3002) tunnel barrels. CONCLUSION: This study demonstrated that, in addition to being the optimum modality for assessment of soft tissue injury of the knee, a high-resolution 3D turbo spin echo proton density sequence can provide an accurate assessment of tunnel placement, without the use of ionizing radiation. Therefore, this protocol provides the foundation for an objective standardized platform to quantitatively evaluate the location of ACL bone tunnels and graft orientation for routine postoperative assessment, presurgical planning, and evaluation of clinical outcomes. PMID- 29589955 TI - Open Latarjet Procedures Produce Better Outcomes in Competitive Athletes Compared With Recreational Athletes: A Clinical Comparative Study of 106 Athletes Aged Under 30 Years. AB - BACKGROUND: In cases of shoulder stabilization for anterior instability, the main goals of the surgery are a rapid and efficient return to sports and excellent long-term outcomes without recurrence of dislocation, particularly in young and competitive athletes. PURPOSE: To determine whether outcomes of open Latarjet procedure (OLPs) depend on the level of sports practiced by patients and to report clinical scores and complication rates for OLP at a minimum follow-up of 2 years. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective comparative study was conducted for all patients who underwent OLP by the senior author (J.B.) between July 2007 and December 2012. The indication for OLP at the authors' institution was a minimum of 2 episodes of dislocation and/or subluxation, a positive apprehension test result in the cocking position, an Instability Severity Index Score more than 2, and evidence of anterior instability lesions on computed tomography arthrograms. The 106 included patients (110 shoulders) with a mean follow-up of 46 months were compared in 2 groups depending on sport activities: 57 (54%) competitive athletes and 49 (46%) recreational athletes. The principal outcome measure was evidence of recurrent instability. The secondary outcome measures were clinical scores related to anterior instability and related to sport practice: Rowe score, Oxford Shoulder Instability Score (OSIS), Western Ontario Shoulder Instability Index, and level of satisfaction. RESULTS: Of the 106 patients, 3 reported recurrence of shoulder dislocation: 2 competitive athletes (3.5%; 95% CI, 0.9%-11.2%) and 1 recreational athlete (2%; 95% CI, 0.4%-10.7%) ( P = .684). The persistent apprehension test result was positive in 7 competitive athletes (11.5%) and in 5 recreational athletes (10%) ( P = .566). The Rowe scores improved from 56.3 +/- 13.2 (range, 30-80) preoperatively to 84.2 +/- 16.4 (range, 30-100) postoperatively in competitive athletes and from 55.0 +/- 11.0 (range, 35-80) to 69.5 +/- 22.0 (range, 15-100) in recreational athletes ( P < .001). The net improvement in Rowe scores was significantly greater in competitive athletes (27.9 +/- 21.7) compared with recreational athletes (14.5 +/- 24.4) ( P = .006). The scores unrelated to sport activity (Oxford Shoulder Instability Score and Simple Shoulder Test) were similar for the 2 groups. All 57 (100%) competitive athletes and 34 (69.4%) recreational athletes resumed their previous sports practice, at the same level or higher than before their injury (respectively, 78.9% and 42.9%; P = .004). CONCLUSION: The OLP could be considered for primary shoulder stabilization, particularly in competitive athletes, who have high functional demands and great risks of redislocation.

PMID- 29589956 TI - Associations of Early Treatments for Low-Back Pain with Military Readiness Outcomes. AB - BACKGROUND: Chronic low-back pain (LBP) is a frequent cause of work absence and disability, and is frequently associated with long-term use of opioids. OBJECTIVE: To describe military readiness-related outcomes at follow-up in soldiers with LBP grouped by the type of early treatment received for their LBP. Treatment groups were based on receipt of opioid or tramadol prescription and receipt of nonpharmacologic treatment modalities (NPT). Design, Subjects, Measures: A retrospective longitudinal analysis of U.S. soldiers with new LBP episodes persisting more than 90 days between October 2012 and September 2014. Early treatment groups were constructed based on utilization of services within 30 days of the first LBP claim. Outcomes were measured 91-365 days after the first LBP claim. Outcomes were constructed to measure five indicators of limitations of military readiness: military duty limitations, pain-related hospitalization, emergency room visit for LBP, pain score of moderate/severe, and prescription for opioid/tramadol. RESULTS: Among soldiers with no opioid receipt in the prior 90 days, there were 30,612 new episodes of LBP, which persisted more than 90 days. Multivariable logistic regression models found that compared to the reference group (no NPT, no opioids/tramadol receipt), soldiers who received early NPT-only had lower likelihoods for military duty limitations, pain-related hospitalization, and opioid/tramadol prescription at follow-up, while soldiers' that started with opioid receipt (at alone or follow-up in conjunction with NPT) exhibited higher likelihoods on many of these negative outcomes. CONCLUSION: This observational study of soldiers with a new episode of LBP and no opioid receipt in the prior 90 days suggests that early receipt of NPT may be associated with small, significant gains in ability to function as a soldier and reduced reliance on opioid/tramadol medication. While further research is warranted, increased access to NPT at the beginning of LBP episodes should be considered. PMID- 29589958 TI - Regulation of RNA Polymerase I TranscriptioninDevelopment, Disease, and Aging. AB - Ribosome biogenesis is a complex and highly energy-demanding process that requires the concerted action of all three nuclear RNA polymerases (Pol I-III) in eukaryotes. The three largest ribosomal RNAs (rRNAs) originate from a precursor transcript (pre-rRNA) that is encoded by multicopy genes located in the nucleolus. Transcription of these rRNA genes (rDNA) by Pol I is the key regulation step in ribosome production and is tightly controlled by an intricate network of signaling pathways and epigenetic mechanisms. In this article, we give an overview of the composition of the basal Pol I machinery and rDNA chromatin. We discuss rRNA gene regulation in response to environmental signals and developmental cues and focus on perturbations occurring in diseases linked to either excessive or limited rRNA levels. Finally, we discuss the emerging view that rDNA integrity and activity may be involved in the aging process. PMID- 29589960 TI - A longitudinal large-scale objective sleep data analysis revealed a seasonal sleep variation in the Japanese population. AB - In the contemporary era, when life habits are largely determined by social needs and individual preferences, sleep is nevertheless affected by seasonal environmental changes. Japan has large seasonal and geographical alterations of photoperiod and climate. Japan does not adopt the daylight saving time (DST) system, making it a suitable country for the study of seasonal variations in natural human sleep. The aim of this study was to analyze the seasonal changes in the sleep properties (timing and quality) and identify their relationship with environmental changes. Here, we report an analysis of objective sleep data of 691 161 nights collected from 1856 Japanese participants (age 20-79 years, male 91%, female 9%) for 3 years using contactless biomotion sensors. Sleep onset time did not show clear seasonal variation, but sleep offset time showed a seasonal change with a single latest peak in winter. Seasonal variation was larger during weekends than during weekdays. Sleep offset time well correlated with sunrise time but was different in spring and autumn even when the sunrise time was same, suggesting the role of temperature difference. Sleep quality, estimated by wake time after sleep onset and sleep efficiency, showed seasonal changes with the lowest trough around mid-summer. In conclusion, despite profound social influences, the timing and quality of sleep showed seasonal fluctuation indicating that they were influenced by climate factors even in the developed country. PMID- 29589959 TI - Understanding and Improving the Activity of Flavin-Dependent Halogenases via Random and Targeted Mutagenesis. AB - Flavin-dependent halogenases (FDHs) catalyze the halogenation of organic substrates by coordinating reactions of reduced flavin, molecular oxygen, and chloride. Targeted and random mutagenesis of these enzymes have been used to both understand and alter their reactivity. These studies have led to insights into residues essential for catalysis and FDH variants with improved stability, expanded substrate scope, and altered site selectivity. Mutations throughout FDH structures have contributed to all of these advances. More recent studies have sought to rationalize the impact of these mutations on FDH function and to identify new FDHs to deepen our understanding of this enzyme class and to expand their utility for biocatalytic applications. PMID- 29589961 TI - 3D Printed Organ Models for Surgical Applications. AB - Medical errors are a major concern in clinical practice, suggesting the need for advanced surgical aids for preoperative planning and rehearsal. Conventionally, CT and MRI scans, as well as 3D visualization techniques, have been utilized as the primary tools for surgical planning. While effective, it would be useful if additional aids could be developed and utilized in particularly complex procedures involving unusual anatomical abnormalities that could benefit from tangible objects providing spatial sense, anatomical accuracy, and tactile feedback. Recent advancements in 3D printing technologies have facilitated the creation of patient-specific organ models with the purpose of providing an effective solution for preoperative planning, rehearsal, and spatiotemporal mapping. Here, we review the state-of-the-art in 3D printed, patient-specific organ models with an emphasis on 3D printing material systems, integrated functionalities, and their corresponding surgical applications and implications. Prior limitations, current progress, and future perspectives in this important area are also broadly discussed. PMID- 29589962 TI - Clinical Outcome of Resected Remnant Pancreatic Cancer After Resection of the Primary Pancreatic Cancer. AB - PURPOSE: Pancreatic cancer (PC) has high morbidity and mortality rates, with a poor prognosis and frequent recurrence. The postresection survival rate has increased but remains low, and remnant PC is becoming more common. This review evaluates the current literature pertaining to the clinical outcomes of patients with resected remnant PC. MATERIAL AND METHODS: We reviewed publications on remnant PC that included repeated and completion pancreatectomy. Clinicophysiological data were analyzed, and survival rates were calculated using the Kaplan-Meier method. Remnant PC was defined by negative margins at the initial operation, a cancer-free interval >1 year, and presence in the remnant pancreas. RESULTS: Forty-nine cases of remnant PC selected from the literature were examined. Primary and remnant PCs had the same histopathological features in 29 of 45 patients (64.4%). The median disease-free interval was 44.3 months (12 143 months). The 1- and 3-year survival rates after repeat pancreatectomy were 81.5% and 50%, respectively, and the median survival time was 32 months. The age of the patient at the time of the first operation independently predicted survival in a multivariate analysis. CONCLUSION: In long-term survivors after curative resection for PC, resectable remnant PCs should be aggressively removed to improve prognosis. PMID- 29589963 TI - Serotyping and Genotyping Characterization of Pathogenic Escherichia coli Strains in Kimchi and Determination of Their Kinetic Behavior in Cabbage Kimchi During Fermentation. AB - This study determined the serotyping and genotyping properties of Escherichia coli strains isolated from kimchi and various raw vegetables used for kimchi preparation. In addition, the kinetic behavior of E. coli strains in kimchi during fermentation was also determined using a predictive microbiological model. The study results revealed that E. coli isolated from napa cabbage (3.3%; 1/30) was enterohemorrhagic E. coli (O6:H34), and eight typical colonies isolated from kimchi (15%; 6/40) were enteropathogenic E. coli (H8, H8, H12, H34, H30, O20:H39, H39, and H12). The genetic correlation of the strains did not show close genetic correlations. On the other hand, the kinetic behavior of E. coli strains in kimchi during fermentation using a predictive Baranyi model (primary model) and a polynomial equation (secondary model), followed by validation by calculating root mean square error (RMSE), revealed that the pathogenic E. coli cell counts increased (with RMSE of 0.280 in growth curve) in the early stage of fermentation and decreased (with RMSE of 0.920 in death curve) thereafter depending on fermentation temperature. Therefore, this finding indicated that pathogenic E. coli isolated from kimchi and related vegetables underwent proliferation at the beginning of fermentation, which decreased thereafter. Thus, these results of this study suggest intake of sufficiently fermented kimchi to prevent potential foodborne illness due to pathogenic E. coli. PMID- 29589965 TI - Do pre-clinical multiple sclerosis models allow us to measure neurodegeneration and clinical progression? PMID- 29589964 TI - Screening and surveillance-principles and practice. AB - Health screening can only be applied to populations, not individuals. For it to be effective, the initial screening test must be acceptable and reasonably accurate, the disease must be treatable with better outcomes when treated early and the harm and cost associated with screening must not outweigh its benefits. Robust evidence is therefore required before systematic screening is implemented. Surveillance implies the testing of people at high risk of disease and is therefore distinct from screening in both scale (smaller) and intensity (greater). In both cases, however, clear information must be provided to potential participants so that they can weigh up the balance of benefit and harm before deciding on whether or not to engage in the process. PMID- 29589966 TI - Vaccine candidates against leishmania under current research. AB - INTRODUCTION: The search for vaccines to prevent human leishmaniasis is an active field of investigation aimed to prevent the devastating effects of this family of diseases on human health. The design and commercialization of several vaccines against canine leishmaniasis is a hopeful advance toward the achievement of a human vaccine. Areas covered: This review includes a summary of the most relevant immunological aspects accompanying leishmaniasis in natural hosts as well as a description of the latest advances in the multiple strategies that are being followed to develop leishmanial prophylactic vaccines. We have combined citations of the latest specialized reviews with research articles presenting the most recent results. Expert commentary: Achieving safe, effective, durable and low cost prophylactic vaccines against leishmaniasis is still a major challenge. These vaccines should control not only parasite progression, but also the accompanying pathology, which results from an imbalanced interaction between the infectious agent and the human host immune system. Different strategies for development of vaccines are currently under investigation. They range from the use of live non-pathogenic vectors to the employment of subunit vaccines combined with adjuvants and/or delivery systems inducing cell-mediated immunity. PMID- 29589967 TI - Affect-Aware Adaptive Tutoring Based on Human-Automation Etiquette Strategies. AB - OBJECTIVE: We investigated adapting the interaction style of intelligent tutoring system (ITS) feedback based on human-automation etiquette strategies. BACKGROUND: Most ITSs adapt the content difficulty level, adapt the feedback timing, or provide extra content when they detect cognitive or affective decrements. Our previous work demonstrated that changing the interaction style via different feedback etiquette strategies has differential effects on students' motivation, confidence, satisfaction, and performance. The best etiquette strategy was also determined by user frustration. METHOD: Based on these findings, a rule set was developed that systemically selected the proper etiquette strategy to address one of four learning factors (motivation, confidence, satisfaction, and performance) under two different levels of user frustration. We explored whether etiquette strategy selection based on this rule set (systematic) or random changes in etiquette strategy for a given level of frustration affected the four learning factors. Participants solved mathematics problems under different frustration conditions with feedback that adapted dynamic changes in etiquette strategies either systematically or randomly. RESULTS: The results demonstrated that feedback with etiquette strategies chosen systematically via the rule set could selectively target and improve motivation, confidence, satisfaction, and performance more than changing etiquette strategies randomly. The systematic adaptation was effective no matter the level of frustration for the participant. CONCLUSION: If computer tutors can vary the interaction style to effectively mitigate negative emotions, then ITS designers would have one more mechanism in which to design affect-aware adaptations that provide the proper responses in situations where human emotions affect the ability to learn. PMID- 29589968 TI - Radiographic features of lingual mandibular bone depression using dental cone beam computed tomography. AB - OBJECTIVES: To describe accurately the radiographic characteristics of lingual mandibular bone depression (LMBD) using CBCT images. METHODS: This study included 30 cases of LMBD with CBCT images from 29 patients. Age, sex, location, shape, size, and the relationships of the LMBDs to adjacent anatomical structures such as the mandibular inferior cortex and mandibular canal were recorded. The correlation between age and size was evaluated using Pearson's correlation coefficient. RESULTS: The average age of the patients was 57 years. LMBDs occurred primarily in males (93%), occurrence in the right (n = 14) and left (n = 16) mandibles was approximately equal. The shapes were ovoid, round, peanut, triangular, or rectangular on panoramic radiographs. The occurrences in the molar, distal to the molar, and ramus regions were 63.3, 33.3, and 3.3% respectively. The mean size on CBCT was 15.4 mm in length, 11.2 mm in height, and 6.4 mm in depth. The relationship to the mandibular canal was categorized as separated (48.2%), contacted (31%), or go-through (20.7%). The relationship to the mandibular inferior cortex was classified as separated (20.7%), contacted (27.6%), or resorbed (51.7%). The Pearson's correlation coefficient showed a positive correlation between age and depth (r = 0.38; p = 0.038). CONCLUSIONS: The typical features of a LMBD were ovoid, round or mutilobated radiolucent shape, well-defined sclerotic border, and position in the posterior area of the mandible between the mandibular canal and inferior mandibular cortex. The buccolingual depth of LMBD was deeper with increasing age. PMID- 29589969 TI - Checkpoint inhibitors and acute myelogenous leukemia: promises and challenges. AB - INTRODUCTION: Immunity, for treatment of acute myelogenous leukemia (AML), has been leveraged historically in the form of allogeneic stem cell transplantation. Checkpoint inhibitors (CPI) as positive modulators of immune response have been recent major breakthroughs in solid tumors. Areas covered: Emerging concepts and clinical data with CPIs in acute Myeloid Leukemia - the focus of this review- will be discussed. CPIs can potentially be effective in absence of 'actionable' mutations and are expected to be effective against poor-risk AML. Immune inhibitory checkpoint molecules are upregulated in both de novo and relapsed AML. Similar data also suggest role of checkpoint molecules in mediating resistance particularly to hypomethylating agent (HMA) therapy, which can potentially be reversed by using checkpoint inhibitors. Expert commentary: Ongoing clinical trials in combination with HMAs are showing early promise, with doubling of response than that seen in historic controls. The optimal combinations of CPIs and the optimal space that they will fit in the continuum of AML therapies need lot of in depth work. PMID- 29589970 TI - Imaging of the Tibionavicular Ligament, and Its Potential Role in Adult Acquired Flatfoot Deformity. AB - BACKGROUND: The spring ligament is an important medial arch stabilizer. However, when disrupted, it does not cause planovalgus deformity until the foot is cyclically loaded. We propose that the tibionavicular (TN) ligament plays an important role. However, this ligament is not imaged in routine magnetic resonance imaging (MRI) sequences. METHODS: A prospective case-control study using a novel MRI sequence to image the TN ligament in 20 normal feet creating a baseline appearance of the ligament. We then scanned 20 patients with adult acquired flatfoot deformity (AAFD). All patients had weightbearing anteroposterior and lateral radiographs. We followed up patients, the end point being surgery or 18 months' follow-up. RESULTS: The normal ligament was reliably identified on the novel sequences. It had a reproducible appearance in 2 views, and consistent length and width. Two groups of patients were identified in the AAFD cohort: Normal TN (11/20) (The mean Meary angle was 6.8 degrees) and Abnormal TN (9/20). The ligament was thickened proximally, with distal attenuation and intrasubstance edema. On sagittal sequence, it had dorsal bulging and high signal. The mean Meary angle was 13.2 degrees ( P = .013). All patients had posterior tibial tendon dysfunction and 8 had spring ligament complex attenuation. Five patients have undergone corrective surgery compared to none in the other group. CONCLUSION: This study adds to the evidence that AAFD is multifactorial. With this imaging technique, we were able to reliably image the TN ligament. We hope that including this sequence into routine scanning will help us understand its role in flatfoot deformity. This poses the question of whether this structure will play a role in reconstructive surgery in future. LEVEL OF EVIDENCE: Level II, prospective comparative study.

AB - INTRODUCTION: Primary immunodeficiencies (PID) are genetic immune disorders causing increased predisposition to infections and autoimmunity. The only curative procedure is hematopoietic stem cell transplantation (HSCT), results from which have improved dramatically since 2000. Complications remain a serious issue, especially in HLA non-identical transplantation. In PID patients, persistent infection and autoimmunity with end-organ damage cause particular problems with approach to transplantation. This article examines these, emphasising approach to management and consequences. Areas covered: It is challenging to know which patients should be offered HSCT. As new diseases are discovered, data are required to determine natural history, and HSCT outcomes. Treatment of adults can be challenging, although HSCT outcomes are encouraging. New methods of T-lymphocyte depletion show results comparable to those of matched sibling donor transplants. New cellular therapies to treat viral infections show promising results, and immunomodulatory methods are successful in treating acute graft-versus-host disease. Expert commentary: New T-lymphocyte depletion methods are a paradigm shift in approach to HSCT for PID. In combination with new cellular approaches to treating viral infection, immunomodulatory approaches to acute graft-versus-host disease and better understanding of endothelial activation syndromes, survival approaches 90%. Widespread introduction of newborn screening for severe combined immunodeficiencies will improve survival further. PMID- 29589972 TI - Beyond "Facebook Addiction": The Role of Cognitive-Related Factors and Psychiatric Distress in Social Networking Site Addiction. AB - The use of social networking sites (SNSs) is rapidly increasing as billions of individuals use SNS platforms regularly to communicate with other users, follow the news, and play browser games. Given the widespread use of SNS platforms, investigating the potential predictors of addictive SNS use beyond Facebook use has become paramount given that most studies so far focused on "Facebook addiction." In this study, a total of 511 English-speaking SNS users (58.1% young adults aged 20-35 years; 64.6% female) were recruited online and asked to complete a battery of standardized psychometric tools assessing participants' sociodemographic characteristics, SNS preferences and patterns of use, SNS addiction, preference for online social interaction, maladaptive cognitions, fear of missing out (FoMo), dysfunctional emotion regulation, and general psychiatric distress. Overall, about 4.9% (n = 25) of all participants could be classed as having a high SNS addiction risk profile. Moreover, the results further indicated that FoMo (beta = 0.38), maladaptive cognitions (beta = 0.25), and psychiatric distress (beta = 0.12) significantly predicted SNS addiction (i.e., p < 0.0001) and accounted for about 61% of the total variance in SNS addiction, with FoMo providing the strongest predictive contribution over and above the effects of sociodemographic variables and patterns of SNS use. The implications of the present findings were discussed in light of extant literature on behavioral addictions and Facebook addiction and further considerations were provided regarding the potential clinical implications for cognitive-based psychological treatment approaches to SNS addiction. PMID- 29589973 TI - Engineered Ribosomes for Basic Science and Synthetic Biology. AB - The ribosome is the cell's factory for protein synthesis. With protein synthesis rates of up to 20 amino acids per second and at an accuracy of 99.99%, the extraordinary catalytic capacity of the bacterial translation machinery has attracted extensive efforts to engineer, reconstruct, and repurpose it for biochemical studies and novel functions. Despite these efforts, the potential for harnessing the translation apparatus to manufacture bio-based products beyond natural limits remains underexploited, and fundamental constraints on the chemistry that the ribosome's RNA-based active site can carry out are unknown. This review aims to cover the past and present advances in ribosome design and engineering to understand the fundamental biology of the ribosome to facilitate the construction of synthetic manufacturing machines. The prospects for the development of engineered, or designer, ribosomes for novel polymer synthesis are reviewed, future challenges are considered, and promising advances in a variety of applications are discussed. PMID- 29589974 TI - Coronary chronic total occlusion intervention: utility or futility. AB - INTRODUCTION: Despite an incidence of about 18-52% of the patients undergoing coronary angiography, chronic total occlusions (CTO) are rarely revascularised by percutaneous angioplasty (PCI). Nevertheless, current evidence suggests that successful CTO angioplasty improves symptoms, quality of life and long-term survival. During the last decade, the improvement of specific tools and techniques for these complex procedures, and the increasing experience of operators, have led to the achievement of success and complication rates almost equivalent to non-CTO angioplasty. Areas covered: This review focuses on the clinical benefits of CTO revascularization and on appropriate patient selection. Expert commentary: Current evidence suggests that successful CTO-PCI improves symptoms, quality of life and long-term survival. During the last years, the improvement of specific techniques for these complex procedures and the increasing experience of operators, have led to the achievement of success and complication rates almost equivalent to non-CTO lesion angioplasty. PMID- 29589975 TI - The Photochemistry of Unprotected DNA and DNA inside Bacillus subtilis Spores Exposed to Simulated Martian Surface Conditions of Atmospheric Composition, Temperature, Pressure, and Solar Radiation. AB - DNA is considered a potential biomarker for life-detection experiments destined for Mars. Experiments were conducted to examine the photochemistry of bacterial DNA, either unprotected or within Bacillus subtilis spores, in response to exposure to simulated martian surface conditions consisting of the following: temperature (-10 degrees C), pressure (0.7 kPa), atmospheric composition [CO2 (95.54%), N2 (2.7%), Ar (1.6%), O2 (0.13%), and H2O (0.03%)], and UV-visible-near IR solar radiation spectrum (200-1100 nm) calibrated to 4 W/m2 of UVC (200-280 nm). While the majority (99.9%) of viable spores deposited in multiple layers on spacecraft-qualified aluminum coupons were inactivated within 5 min, a detectable fraction survived for up to the equivalent of ~115 martian sols. Spore photoproduct (SP) was the major lesion detected in spore DNA, with minor amounts of cyclobutane pyrimidine dimers (CPD), in the order TT CPD > TC CPD >> CT CPD. In addition, the (6-4)TC, but not the (6-4)TT, photoproduct was detected in spore DNA. When unprotected DNA was exposed to simulated martian conditions, all photoproducts were detected. Surprisingly, the (6-4)TC photoproduct was the major photoproduct, followed by SP ~ TT CPD > TC CPD > (6-4)TT > CT CPD > CC CPD. Differences in the photochemistry of unprotected DNA and spore DNA in response to simulated martian surface conditions versus laboratory conditions are reviewed and discussed. The results have implications for the planning of future life detection experiments that use DNA as the target, and for the long-term persistence on Mars of forward contaminants or their DNA.

PMID- 29589977 TI - A Meta-analysis of antihypertensive effect of telmisartan versus candesartan in patients with essential hypertension. AB - OBJECTIVE: The comparison of antihypertensive effects between telmisartan and candesartan in patients with essential hypertension has been investigated in several small studies. The results were not consistent. We performed this meta analysis determining the antihypertensive effect of telmisartan versus candesartan in these patients. METHODS: We searched Pubmed, Web of Science, and Cochrane Central for all published studies comparing the antihypertensive effects between telmisartan and candesartan in patients with essential hypertension. RESULTS: The antihypertensive effects were assessed in 302 patients included in 4 trials with a mean follow-up of 10 +/- 4 weeks. There were no significant differences between telmisartan and candesartan in reduction of systolic blood pressure (SBP) and diastolic BP (DBP) in patients with essential hypertension (weighted mean differences (WMD) for SBP 1.98 mm Hg (95% confidence interval (CI), -0.53, 4.49), p > 0.05; WMD for DBP 0.26 mm Hg (95% CI, -1.65, 2.16), p > 0.05), respectively. In a sub-analysis including 2 randomized studies, there was not a significant difference for the reduction of SBP (WMD 0.90 (95% CI, -2.88, 4.68) mm Hg, p > 0.05) or DBP (WMD -0.80 (95% CI, -3.40, 1.81) mm Hg, p > 0.05) treated with telmisartan or candesartan. CONCLUSIONS: This meta-analysis provides the evidence that the antihypertensive effects of telmisartan and candesartan are similar on SBP and DBP reduction in patients with essential hypertension, suggesting that strict designed randomized controlled trial would be helpful to compare antihypertensive effects of angiotensin II receptor blockers (ARBs) and improve the choice of ARBs in antihypertensive therapy. PMID- 29589978 TI - ZAP70 expression enhances chemokine-driven chronic lymphocytic leukemia cell migration and arrest by valency regulation of integrins. AB - The zeta-associated protein of 70 kDa (ZAP70) is expressed in the aggressive form of B-cell chronic lymphocytic leukemia (CLL). Moreover, the integrin very late antigen (VLA)-1 is highly expressed on subtypes of CLL that are associated with high proliferation rates in the lymph node context. We herein identify a critical role for ZAP70 in chemokine-mediated, inside-out signaling to integrins in trisomy 12 carrying Ohio State University-CLL cell lines derived from a patient with previously treated CLL. We found that ZAP70-positive CLL cells migrated significantly better toward ligands of the lymph node homing chemokine receptors CCR7 and CXCR4 compared with ZAP70-negative cells. In addition, ZAP70-expressing CLL cells adhered more efficiently to integrin ligands under static conditions. We discovered that ZAP70 expression controls chemokine-driven clustering of the integrins VLA-4 and lymphocyte function-associated antigen-1. More precisely, chemokine stimulation resulted in a ZAP70-dependent integrin valency regulation on CLL cells, whereas high-affinity regulation of integrins was independent of ZAP70. Consequently, ZAP70-expressing CLL cells show increased chemokine-driven arrest on immobilized integrin ligands and on chemokine-presenting endothelial cells under physiologic flow conditions. Hence, we describe a novel mechanism showing how ZAP70 controls chemokine-driven valency regulation of integrins and arrest of CLL cells on endothelial cells, a process that might contribute to CLL disease progression.-Laufer, J. M., Lyck, R., Legler, D. F. ZAP70 expression enhances chemokine-driven chronic lymphocytic leukemia cell migration and arrest by valency regulation of integrins. PMID- 29589976 TI - The transluminal attenuation gradient in coronary CT angiography for the detection of hemodynamically significant disease: can all arteries be treated equally? AB - OBJECTIVE: Results of the use of the transluminal attenuation gradient (TAG) at coronary CT angiography (CCTA) to predict hemodynamically significant disease vary widely. This study tested whether diagnostic performance of TAG to predict fractional flow reserve (FFR) <= 0.8 is improved when applied separately to subsets of coronary arteries that carry similar physiological flow. METHODS: 28 patients with 64 * 0.5 mm CCTA and invasive FFR in >=1 major coronary artery were retrospectively evaluated. Two readers assessed TAG in each artery. The receiver operating characteristic (ROC) area under the curve (AUC) was used to assess the diagnostic performance of TAG to detect hemodynamically significant disease following a clinical use rule [negative: FFR > 0.8 or <= 25% diameter stenosis (DS) at invasive catheter angiography; positive: FFR <= 0.8 or >= 90% DS at invasive catheter angiography]. ROC AUC was compared for all arteries pooled together, vs separately for arteries carrying similar physiological flow (Group 1: all left anterior descending plus right-dominant left circumflex; Group 2: right-dominant RCA plus left/co-dominant left circumflex). RESULTS: Of the 84 arteries, 30 had FFR measurements, 30 had <=25% DS and 13 had >=90% DS. 11 arteries with 26-89% DS and no FFR measurement were excluded. TAG interobserver reproducibility was excellent (Pearson r = 0.954, Bland-Altman bias: 0.224 Hounsfield unit cm-1). ROC AUC to detect hemodynamically significant disease was higher when considering arteries separately (Group 1 AUC = 0.841, p = 0.039; Group 2 AUC = 0.840, p = 0.188), than when pooling all arteries together (AUC = 0.661). CONCLUSION: Incorporating information on the physiology of coronary flow via the particular vessel interrogated and coronary dominance may improve the accuracy of TAG, a simple measurement that can be quickly performed at the time of CCTA interpretation to detect hemodynamically significant stenosis in individual coronary arteries. Advances in knowledge: The interpretation of TAG may benefit by incorporating information regarding which coronary artery is being interrogated. PMID- 29589979 TI - Impact of Orofacial Dysfunction on the Quality of Life of Adult Patients With Cleft Lip and Palate. AB - OBJECTIVE: This study assessed the prevalence of orofacial dysfunctions (ODs) and quality of life (QoL) in adults with and without a cleft lip and palate. DESIGN: Cross sectional. SETTING: Craniofacial Center, Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, Sao Paulo, Brazil. METHODS: The study was composed of a sample of 120 patients: 60 adults in the cleft lip and palate group (CLPG) and 60 adults in the control group with no craniofacial anomalies. Each patient underwent an interview and clinical examination, using the Nordic Orofacial Test Screening (NOT-S) and the 36-Item Short Form Survey. Data were analyzed using Mann-Whitney U test, chi2, and the Spearman correlation coefficients. RESULTS: There was a higher prevalence of OD in CLPG ( P < .001) on the NOT-S. The adults in the CLPG had higher QoL in the areas of general health ( P = .003), physical function ( P = .014), social function ( P < .001), and vitality ( P = .006). The CLPG had significant associations between higher OD and lower QoL for general health ( P = .004), emotional role function ( P = .028), and vitality ( P = .05). CONCLUSION: Orofacial dysfunctions were more prevalent in adults with a cleft, negatively impacting their QoL in general health, emotional role function, and vitality. However, adults with a cleft also had significantly higher QoL, reflecting possible resiliency when compared to adults without a cleft. PMID- 29589981 TI - Guideline Values for Minimum Nasal Cross-Sectional Area in Children. AB - OBJECTIVE: The purpose was to determine age-specific values of the minimum cross sectional area of the nasal airway in children without cleft lip or palate and to assess whether gender differences occur with growth in order to develop guidelines for assessment in children with clefts. PARTICIPANTS: All schoolchildren aged 8 to 17 years who met the research criteria were studied during rest breathing using the pressure-flow technique. The children came from a rural area of 3800 inhabitants. Consecutive age cohorts were used for comparisons. RESULTS: Nasal cross-sectional area increased in females from 0.38 cm2 in 8-year-olds to 0.58 cm2 in 17-year-olds. There was a decrease in size at ages 10 to 11 and 14 to 15 years. In males, the area increased from 0.40 to 0.68 cm2 and decreased slightly from 9 to 10 and 14 to 15 years. The annual changes were statistically significant in females between 8 and 9 and 11 to 13 years of age, and in males from 11 to 12, 13 to 14, and 15 to 17 years of age. Across gender, the only significant difference occurred at age 16. CONCLUSIONS: Our results indicate that the increase in nasal airway size is not consistent during growth. Nasal airway size showed almost equal values for both genders in young children but was systematically larger in boys from 14 years of age on. The results refer that by 17 years of age nasal airway may not have reached adult size in males. PMID- 29589980 TI - Le Fort III Distraction With Internal vs External Distractors: A Cephalometric Analysis. AB - OBJECTIVE: This study compares the change in midface position following Le Fort III advancement using either rigid external distraction (group 1) or internal distraction (group 2). We hypothesized that, with reference to right-facing cephalometry, internal distraction would result in increased clockwise rotation and inferior displacement of the midface. DESIGN: Le Fort III osteotomies and standardized distraction protocols were performed on 10 cadaveric specimens per group. Right-facing lateral cephalograms were traced and compared across time points to determine change in position at points orbitale, anterior nasal spine (ANS), A-point, and angle ANB. SETTING: Institutional. PATIENTS, PARTICIPANTS: Twenty cadaveric head specimens. INTERVENTIONS: Standard subcranial Le Fort III osteotomies were performed from a coronal approach and adequately mobilized. The specified distraction mechanism was applied and advanced by 15 mm. MAIN OUTCOME MEASURE(S): Changes of position were calculated at various skeletal landmarks: orbitale, ANS, A-point, and ANB. RESULTS: Group 1 demonstrated relatively uniform x-axis advancement with minimal inferior repositioning at the A-point, ANS, and orbitale. Group 2 demonstrated marked variation in x-axis advancement among the 3 points, along with a significant inferior repositioning and clockwise rotation of the midface ( P < .0001). CONCLUSION: External distraction resulted in more uniform advancement of the midface, whereas internal distraction resulted in greater clockwise rotation and inferior displacement. External distraction appears to provide increased vector control of the midface, which is important in creating a customized distraction plan based on the patient's individual occlusal and skeletal needs.

AB - Kabuki syndrome (KS) is a rare disorder characterized by somatic and psychological disturbances including special face morphology, skeletal anomalies, and other systemic disorders. Because of the diverse clinical manifestation, the management of a patient with KS may involve several medical and dental specialists, including orthodontics. The aim of the article is to present successful orthodontic treatment performed in a 14-year-old boy diagnosed with the KS. Dental relations and smile aesthetics were normalized after orthodontic treatment; however, problems with patient compliance and cooperation and an increased risk of root resorption may influence treatment outcomes. Interdisciplinary cooperation between medical and dental specialists is essential in patients with KS. PMID- 29589984 TI - The Effect of Calcium Dobesilate on Liver Damage in Experimental Obstructive Jaundice. AB - : Purpose/Aim of the study: Inflammation and oxidative stress are two significant factors affecting the degree of liver damage in obstructive jaundice. The aim of this study was to evaluate the effect of calcium dobesilate (CaDob), an effective antioxidant and anti-inflammatory drug, on damage to liver caused by experimental obstructive jaundice. MATERIALS AND METHODS: 30 rats in total were randomly placed into three groups, each group consisting of 10 rats. The sham group (Group 1) only received solely laparotomy. In the control group (Group 2), ligation was applied to the biliary tract and no treatment was implemented. In the CaDob group (Group 3), following ligation of the biliary tract, 100 mg/kg/day CaDob was implemented via an orogastric tube for a 10-day period. Liver tissue and blood samples were taken for histopathological and biochemical examination. RESULTS: The CaDob group had significantly lower test values for serum liver functions when compared to the control group. Statistically lower levels of tissue malondialdehyde (MDA) and fluorescent oxidation products (FOP) were detected in the CaDob group, and the CaDob group had significantly higher levels of sulfydryl (SH) than the control group. Histopathological scores in the CaDob group were found out to be statistically less than the scores the control group received (p < 0.05). CONCLUSIONS: CaDob treatment repaired the histpatological changes induced by bile duct ligation. The hepatoprotective effects of CaDob can be associated with its antioxidant properties of the drug. PMID- 29589983 TI - A Quality Improvement Initiative to Improve Feeding and Growth of Infants With Cleft Lip and/or Palate. AB - OBJECTIVE: The purpose of this quality improvement initiative was to improve feeding and growth outcomes in infants with cleft lip and/or palate (CL/P). DESIGN: Institute for Healthcare Improvement quality improvement model. SETTING: Large pediatric academic medical center in the Midwestern United States. PARTICIPANTS: One hundred forty-five infants with nonsyndromic CL/P ages 0 to 12 months. INTERVENTIONS: Key drivers included (1) caregiver education and resources, (2) care coordination and flow, and (3) provider education and training. Interventions were designed around these themes and included targeting improved team communication, increased social work consultations, patient tracking, staff education, improved access to feeding equipment, and the launch of a new cleft palate feeding team. MAIN OUTCOME MEASURE(S): The primary outcome measure was the percentage of new patients with CL/P who met criteria for failure to thrive (FTT) per month. The secondary outcome measure was the frequency of hospitalization for infants with CL/P with a primary reason for admission of feeding difficulties or FTT. RESULTS: The institutional FTT rate for infants with CL/P decreased from 17% to 7% ( P < .003). The frequency of hospitalization for FTT improved from once every 30 days to once every 118 days. CONCLUSIONS: Targeted interventions aimed at improving feeding efficiency and effectiveness, as well as changes in care delivery models, can reliably promote improvements in feeding and growth outcomes for infants with CL/P, even with psychosocial risk factors present. PMID- 29589985 TI - A giant dermoid cyst of the orbit. AB - To describe a unique case of a non-germinomatous germ cell tumor, a giant orbital dermoid, present in adulthood. A 31-year-old male presented in our clinic with gradual, painless, progressive proptosis in the left eye since 28 years associated with gradual loss of vision. The left eye showed gross proptosis. Ocular structures could not be made out. Computed tomography scan showed a well circumscribed oval heterogeneous mixed solid and cystic lesion completely filling the left orbit with calcification. The differential diagnosis was that of either teratoma or optic nerve glioma. The patient underwent excision of the lesion. Histopathology revealed a capsulated tumor with multiple cystic components filled with blood and eosinophilic material suggestive of a dermoid cyst. Non germinomatous germ cell tumors may present atypically in adults and neglected benign dermoid cysts can attain massive size mimicking malignant lesions.

AB - BACKGROUND: Class III obesity is a global health emergency associated with an increase in the incidence of many other diseases such as type 2 diabetes mellitus, hypertension, hyperlipidemia, cancer, obstructive sleep apnea, nonalcoholic fatty liver disease, osteoarthritis, infertility, and mental health disorders. Minimal work has been published regarding the efficacy of laparoscopic sleeve gastrectomy (LSG) in the veteran population to surgically manage morbid obesity. DESIGN: Retrospective analysis of LSG performed at a Veterans Affairs Medical Center (VAMC) between 2010 and 2017. Veterans were followed from their enrollment in the bariatric program until twelve months following LSG. The primary outcome of interest was excess and total weight loss with resolution of associated comorbidities. RESULTS: Excess weight loss at nine and 12 months was 43.5% and 40.7% and total weight loss was 20.1% and 19.0%, respectively. LSG performed at a VAMC resulted in 86.9% improvement in type 2 diabetes mellitus and a 66.1% improvement in hypertension and 74.3% improvement in hyperlipidemia. Approximately 10.0% of diabetics obtained partial and 9.0% obtained complete resolution of their disease. Similarly, 22.0% of Veterans obtained partial and 13.0% obtained complete resolution from hypertension. Complete resolution from hyperlipidemia was achieved in 8.8% of Veterans. There were no postoperative complications or staple line leaks. CONCLUSION: LSG is a safe and effective tool for morbid obesity with clinical and serological improvements for individuals who are unable to lose weight with medical management alone. PMID- 29589989 TI - A unique allosteric insulin receptor monoclonal antibody that prevents hypoglycemia in the SUR-1-/- mouse model of KATP hyperinsulinism. AB - Loss-of-function mutations of the beta-cell ATP-sensitive potassium channels (KATP) cause the most common and severe form of congenital hyperinsulinism (KATPHI), a disorder of beta-cell function characterized by severe hypoglycemia. Children with KATPHI are typically unresponsive to medical therapy and require pancreatectomy for intractable hypoglycemia. We tested the hypothesis that inhibition of insulin receptor signaling may prevent hypoglycemia in KATPHI. To test this hypothesis, we examined the effect of an antibody allosteric inhibitor of the insulin receptor, XMetD, on fasting plasma glucose in a mouse model of KATPHI (SUR-1-/- mice). SUR-1-/- and wild-type mice received twice weekly intraperitoneal injections of either XMetD or control antibody for 8 wks. Treatment with XMetD significantly decreased insulin sensitivity, and increased hepatic glucose output and fasting plasma glucose. These findings support the potential use of insulin receptor antagonists as a therapeutic approach to control the hypoglycemia in congenital hyperinsulinism. PMID- 29589990 TI - Effect of Previous Abdominal Surgery on Laparoscopic Liver Resection: Analysis of Feasibility and Risk Factors for Conversion. AB - INTRODUCTION: Previous abdominal surgery has traditionally been considered an additional element of difficulty to later laparoscopic procedures. The aim of the study is to analyze the effect of previous surgery on the feasibility and safety of laparoscopic liver resection (LLR), and its role as a risk factor for conversion. MATERIALS AND METHODS: After matching, 349 LLR in patients known for previous abdominal surgery (PS group) were compared with 349 LLR on patients with a virgin abdomen (NPS group). Subgroup analysis included 161 patients with previous upper abdominal surgery (UPS subgroup). Feasibility and safety were evaluated in terms of conversion rate, reasons for conversion and outcomes, and risk factors for conversion assessed via uni/multivariable analysis. RESULTS: Conversion rate was 9.4%, and higher for PS patients compared with NPS patients (13.7% versus 5.1%, P = .021). Difficult adhesiolysis resulted the commonest reason for conversion in PS group (5.7%). However, operative time (P = .840), blood loss (P = .270), transfusion (P = .650), morbidity rate (P = .578), hospital stay (P = .780), and R1 rate (P = .130) were comparable between PS and NPS group. Subgroup analysis confirmed higher conversion rates for UPS patients (23%) compared with both NPS (P = .015) and PS patients (P = .041). Previous surgery emerged as independent risk factor for conversion (P = .033), alongside the postero-superior location and major hepatectomy. CONCLUSION: LLR are feasible in case of previous surgery and proved to be safe and maintain the benefits of LLR carried out in standard settings. However, a history of surgery should be considered a risk factor for conversion. PMID- 29589992 TI - Non-cancer, cancer, and dermal sensitization risk assessment of heavy metals in cosmetics. AB - The heavy metal content of cosmetics may be a cause for concern in that exposure to these metals is associated with adverse consequences. Thus, the aim of this study was to assess consequences attributed to exposure to heavy metals in cosmetics as determined by non-cancer, cancer, and sensitization risks methodologies. The quantification and exposure assessments of aluminum (Al), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), lead (Pb), mercury (Hg), cadmium (Cd), antimony (Sb), and titanium (Ti) were performed by inductively coupled plasma-mass spectrometry. The non-cancer risk assessment of Al, Cr3+, Mn, Fe, Co, Ni, Cu, Zn, Cd, Sb, and Ti in cosmetic samples resulted in a margin of safety (MOS) greater than 100 or a hazard index (HI) of less than 1. However, the probability of lifetime cancer risk (LCR) resulting from dermal exposure to heavy metals from cosmetics exceeded the acceptable risk levels (LCR > 10-5). An exposure-based sensitization quantitative risk assessment determined that the ratios of acceptable exposure level to consumers for Ni, Co, Cu, or Hg were above 1, suggesting an absence of skin-sensitizing potential. For an average daily user of lip cosmetics, the estimated intakes of heavy metals were within the acceptable daily intake (ADI). The percentage of heavy users for which metal intakes exceeded ADIs were 20.37% for Pb, 9.26% for Mn, 1.85% for Cr3+, and 1.85% for Cr6+, respectively. Data suggested that the heavy metals present in cosmetics do not appear to pose a serious risk to health. However, for heavy users of lip cosmetics, contamination with some heavy metals, such as Pb, Mn, and Cr needs to be minimized. PMID- 29589991 TI - Comparison of patient flow and provider efficiency of two delivery strategies for HPV-based cervical cancer screening in Western Kenya: a time and motion study. AB - BACKGROUND: Improving patient flow and reducing over-crowding can improve quality, promptness of care, and patient satisfaction. Given low utilization of preventive care in low-resource countries, improved patient flows are especially important in these settings. OBJECTIVE: Compare patient flow and provider efficiency between two cervical cancer screening strategies via self-collected human papillomavirus (HPV). METHODS: We collected time and motion data for patients screened for cervical cancer in 12 communities in rural Migori County, Kenya as part of a larger cluster randomized trial. Six communities were randomized to screening in community health campaigns (CHCs) and six to screening at government clinics. We quantified patient flow: duration spent on each active stage of screening and wait times, and the number of patients arriving at CHCs and clinics each hour of the day. In addition, for four CHCs, we collected time and motion data for providers, and measured provider efficiency as a ratio of active (service delivery) time to total time spent at the clinic. RESULTS: Total duration of screening visits, at CHCs and clinics was 42 and 87 minutes, respectively (p < 0.001 for difference). Total active time lasted longer at CHCs, with a mean of 28 minutes per patient versus 15 minutes at clinics, largely due to differences in duration for group education (p < 0.001). Wait time for registration at clinics was 36 minutes, explaining most of the difference between settings, but sometimes incorporated other health services. CONCLUSIONS: There is a substantial difference in patient flow at clinics compared to CHCs. Shorter duration at CHCs suggests that the model is favorable for patients in limiting time spent on screening. Future cervical cancer screening programs designed for scale-up should consider how this advantage may enhance satisfaction and uptake. For clinic-based screening programs, efforts could be made towards reducing registration wait times. PMID- 29589993 TI - Incidence of Multidrug-Resistant Organism Among Children Admitted to Pediatric Intensive Care Unit in a Developing Country. AB - AIM: Multidrug-resistant infections are an increasingly common condition particularly in critical care units. This study aimed to determine the incidence and types of resistant bacteria acquired in a pediatric intensive care unit (PICU) of a university hospital. SUBJECT AND METHODS: A prospective study was conducted during the year 2016. All children aged below 16 years were studied for infection development and pattern of susceptibility to various groups of antibiotics. RESULTS: A total of 264 patients were admitted to the PICU: 16 patients had community-acquired infection (CAI), 23 had hospital-acquired infection, and 24 patients had PICU-acquired infection (with 36 episodes) which is equivalent to 14.75 case/1,000 patient days. The study revealed high incidence of resistant organisms in the PICU but more important is the appearance of multi- and extreme drug-resistant bacteria in CAI. The study revealed that gram-negative bacteria were more prevalent in PICU, especially Klebsiella (30.5%), Acinetobacter baumanii (22.22%), and Pseudomonas (16.67%). Infection with resistant organisms in the PICU caused initial treatment failure and increased fourfold risk of mortality. CONCLUSION: The incidence of resistant bacteria especially gram-negative pathogens was very high in the PICU. The top three resistant organisms of concern were Klebsiella, Acinetobacter, and Pseudomonas. This is a global concern that necessitates new strategies. PMID- 29589994 TI - Concurrent Milk Ingestion Decreases Absorption of Levothyroxine. AB - BACKGROUND: Levothyroxine is the most commonly prescribed medication in the United States. Many foods and medications, including calcium supplements, can interfere with levothyroxine absorption. No studies have investigated the effect of cow's milk, a common breakfast staple, on the absorption of oral levothyroxine. Cow's milk contains approximately 450 mg of elemental calcium per 12 oz (355 mL) serving. METHODS: A pharmacokinetic study was conducted in healthy euthyroid subjects to assess levothyroxine absorption with and without concurrent cow's milk consumption. Following an overnight fast, serum total thyroxine (TT4) concentrations were measured at baseline and at one, two, four, and six hours after ingestion of 1000 MUg of oral levothyroxine alone or when co-administered with 12 oz (355 mL) of 2% milk. There was a four-week washout period between the two assessments in each subject. RESULTS: Ten subjects (Mage +/- SD = 33.7 +/- 10.2 years; 60% male) completed the study. The area under the curve (AUC) of TT4 concentrations was significantly lower when levothyroxine was ingested along with 12 oz (355 mL) of 2% cow's milk (M +/- SD = 67.3 +/- 12.1) compared to that with levothyroxine alone (73.5 +/- 17.0; p = 0.02). Also, peak serum TT4 concentrations were significantly lower when cow's milk was co-administered with levothyroxine (M +/- SD = 14.1 +/- 0.8 MUg/dL) than with levothyroxine alone (13.0 +/- 0.9 MUg/dL; p = 0.04). CONCLUSIONS: This is the first study to demonstrate that concurrent cow's milk ingestion reduces oral levothyroxine absorption. The findings support previous literature showing the interference of elemental calcium and food with thyroid hormone absorption. Patients managed with thyroid hormone should be advised to avoid taking their levothyroxine simultaneously with cow's milk. PMID- 29589995 TI - The Role of Discrimination in Care Postponement Among Trans-Feminine Individuals in the U.S. National Transgender Discrimination Survey. AB - PURPOSE: This study examines the associations between discrimination experiences (types and locations) and care postponement among trans-feminine individuals in the United States. METHODS: This secondary, cross-sectional study utilized a subset of the data from the National Transgender Discrimination Survey (n = 2248), specifically for trans-feminine individuals. In this analysis, we examined the relationship between discrimination and primary care postponement. RESULTS: Twenty-six percent (26.25%) of the study sample reported delaying preventive care due to fear of discrimination; 23.98%-46.66% of respondents reported past experiences of discrimination (setting dependent). Discrimination in health and non-health settings and different types of discrimination-being denied services, verbally harassed, or physically assaulted-were all significantly associated with delaying care; respondents reporting discrimination were up to 20 times more likely to postpone care. While discrimination at a health location had the strongest association with care postponement (adjusted odds ratio = 9.65, confidence interval = 7.60-12.24), discrimination in all non-health-related locations was also important. Individuals reporting discrimination in greater numbers of locations and multiple types of discrimination were more likely to postpone care. CONCLUSION: To promote preventive care-seeking, these results affirm the importance of interventions that promote discrimination-free environments for gender minorities. PMID- 29589996 TI - Wealth gradient-based divergence in the prevalence of underweight among women by marital status in Quoc Oai district, Vietnam. AB - BACKGROUND: The prevalence of underweight is high among women in Asian countries, despite nutritional changes in the region. Previous studies have demonstrated independent associations between female body weight, marital status and economic status. However, few studies have investigated possible interaction between marital and economic status in relation to Asian women's body weight. OBJECTIVE: This study aimed to test associations between household wealth, marital status and underweight among women living in the Quoc Oai district of Vietnam and to identify wealth-marital status interaction in relation to body weight in these women. METHODS: Data from 1087 women aged 19-60 years were collected via a baseline community survey conducted in the Quoc Oai district of Hanoi, Vietnam, in 2016. Underweight was defined using an Asian-specific body mass index cut-off (<18.5 kg/m2). Marital status was dichotomized into 'never married' and 'ever married.' Economic status was measured using household wealth index quintiles. Multivariable logistic regressions tested association between wealth and underweight after adjusting for marital status and other confounders. An interaction term (wealth index*marital status) was fitted to determine whether the association between wealth and body weight is modified by marital status. RESULTS: Our results show that underweight was independently associated with a wealth status (odds ratio [OR]: 0.88, 95% confidence interval [CI]: 0.79-0.98, p = 0.026) and ever-married status (OR: 0.50, 95% CI: 0.34-0.75, p = 0.002). A significant interaction effect (OR: 0.67, 95% CI: 0.50-0.90, p = 0.010) indicated that wealthy married women were less likely to be underweight, whereas wealthy never-married women were more likely to be underweight. CONCLUSIONS: Our results suggest that the interaction between wealth and marital status has divergent effects on underweight among Asian women. Interventions to reduce underweight among Asian women should simultaneously consider economic and marital status. PMID- 29589998 TI - Trends in onroad transportation energy and emissions. AB - : Globally, 1.3 billion on-road vehicles consume 79 quadrillion BTU of energy, mostly gasoline and diesel fuels, emit 5.7 gigatonnes of CO2, and emit other pollutants to which approximately 200,000 annual premature deaths are attributed. Improved vehicle energy efficiency and emission controls have helped offset growth in vehicle activity. New technologies are diffusing into the vehicle fleet in response to fuel efficiency and emission standards. Empirical assessment of vehicle emissions is challenging because of myriad fuels and technologies, intervehicle variability, multiple emission processes, variability in operating conditions, and varying capabilities of measurement methods. Fuel economy and emissions regulations have been effective in reducing total emissions of key pollutants. Real-world fuel use and emissions are consistent with official values in the United States but not in Europe or countries that adopt European standards. Portable emission measurements systems, which uncovered a recent emissions cheating scandal, have a key role in regulatory programs to ensure conformity between "real driving emissions" and emission standards. The global vehicle fleet will experience tremendous growth, especially in Asia. Although existing data and modeling tools are useful, they are often based on convenience samples, small sample sizes, large variability, and unquantified uncertainty. Vehicles emit precursors to several important secondary pollutants, including ozone and secondary organic aerosols, which requires a multipollutant emissions and air quality management strategy. Gasoline and diesel are likely to persist as key energy sources to mid-century. Adoption of electric vehicles is not a panacea with regard to greenhouse gas emissions unless coupled with policies to change the power generation mix. Depending on how they are actually implemented and used, autonomous vehicles could lead to very large reductions or increases in energy consumption. Numerous other trends are addressed with regard to technology, emissions controls, vehicle operations, emission measurements, impacts on exposure, and impacts on public health. IMPLICATIONS: Without specific policies to the contrary, fossil fuels are likely to continue to be the major source of on-road vehicle energy consumption. Fuel economy and emission standards are generally effective in achieving reductions per unit of vehicle activity. However, the number of vehicles and miles traveled will increase. Total energy use and emissions depend on factors such as fuels, technologies, land use, demographics, economics, road design, vehicle operation, societal values, and others that affect demand for transportation, mode choice, energy use, and emissions. Thus, there are many opportunities to influence future trends in vehicle energy use and emissions. PMID- 29589997 TI - Rearing Zebrafish on Black Soldier Fly (Hermetia illucens): Biometric, Histological, Spectroscopic, Biochemical, and Molecular Implications. AB - A desirable goal of the aquaculture sector is to replace most of fish meal and fish oil with more sustainable, cost-effective, and environmental friendly ingredients ensuring fish health and welfare standards. Due to minimal environmental impact, compared with most conventional feed commodities, insects deserve a growing attention as candidate ingredients for aquafeeds. The present study investigated, for the first time, the possible application of a 100% insect diet in zebrafish larval rearing. Through a multidisciplinary approach, the major biological responses of fish to the new diets were assessed. Results of biometry, fatty acid composition, expression of genes involved in fish growth, stress response, lipid metabolism, chitinolytic activity, gut inflammation, and liver macromolecular composition suggested a possible application of insect larvae for zebrafish larval rearing. However, further studies are necessary to better understand the use of this insect species in the rearing of fish. PMID- 29589999 TI - Biguanides Metformin and Phenformin Generate Therapeutic Effects via AMP Activated Protein Kinase/Extracellular-Regulated Kinase Pathways in an In Vitro Model of Graves' Orbitopathy. AB - BACKGROUND: It was hypothesized that the biguanides metformin and phenformin, which are anti-hyperglycemic drugs used for diabetes mellitus, would have therapeutic effects in an in vitro model of Graves' orbitopathy (GO). Because adipogenesis, hyaluronan production, and inflammation are considered important in the pathogenesis of GO, this study aimed to determine the therapeutic effects and underlying mechanisms of biguanides on these parameters. METHODS: In vitro experiments were performed using primary cultured orbital fibroblasts from patients with GO. Orbital preadipocyte fibroblasts were allowed to differentiate into adipocytes and were treated with various concentrations of metformin or phenformin. Oil Red O staining was performed to evaluate lipid accumulation within the cells. Western blot analysis was used to measure the expression of adipogenic transcription factors and the phosphorylation of AMP-activated protein kinase and mitogen-activated protein kinase signaling proteins. Hyaluronan production was measured using enzyme-linked immunosorbent assay, and mRNA levels of proinflammatory molecules were determined using real-time polymerase chain reaction after interleukin (IL)-1beta stimulation with or without biguanide treatment. RESULTS: Lipid accumulation during adipogenesis in GO orbital fibroblasts was dose-dependently suppressed by both metformin and phenformin. Adipocyte differentiation was attenuated, and the adipogenic transcription factors peroxisome proliferator-activated receptor gamma and CCAAT-enhancer binding proteins-alpha/beta were downregulated. Furthermore, metformin and phenformin increased the phosphorylation of AMP-activated protein kinase and suppressed extracellular-regulated kinase activation. The IL-1beta-induced hyaluronan production and mRNA expression of IL-6, cyclooxygenase-2, and intercellular adhesion molecule-1 were also significantly suppressed after metformin or phenformin co-treatment. CONCLUSIONS: The present study indicates that the biguanides metformin and phenformin exert an anti-adipogenic and inhibitory effect on hyaluronan production and expression of pro-inflammatory molecules in GO orbital fibroblasts, suggesting that they could potentially be used for the treatment of GO.

PMID- 29590001 TI - Light and Scanning Electron Microscopic Studies of Unionicola tetrafurcatus (Acari: Unionicolidae) Infecting Four Freshwater Bivalve Species and Histopathological Effect On Its Hosts. AB - Water mites of the genus Unionicola are the most common symbionts of freshwater bivalves. During the current investigation, a total of 120 live freshwater mussels representing 5 species, Corbicula fluminea (Veneroida), Coelatura aegyptiaca (Unionoidea), Mutela rostrata, and Chambardia rubens (Mutelidae), were collected from 2 localities in Tura (Helwan Governorate) and El Kanater (Qaluobiya Governorate), Egypt. Only 3 of the 4 bivalve species listed are considered freshwater bivalves (members of Unionoidea). Corbicula fluminea belong to the family Cyrenidae within Veneroida. Collected mussels were dissected and examined for the presence of unionicolid mites. It was found that 30.83% (37/120) were infected with a single mite species, Unionicola tetrafurcatus (Unionicolidae). The highest prevalence was observed during the summer with 83.33% (25/30) whereas the least was observed in autumn, i.e., 33.33% (10/30). Mites were recovered from the gills, gonads, and visceral mass of mussel hosts. Gills of host mussels were the primary site of oviposition for Unionicola mites. Smaller bivalves in size had significantly greater numbers of mites than did larger ones in size. Numbers of mites per host species was variable and the highest prevalence level of 83.33% (25/30) was recorded in Cor. fluminea while the lowest one of 16.66% (5/30) was found in Ch. rubens. Morphological and morphometric characterizations of mites revealed some differences between the present species and other related Unionicola. Histopathological responses of host mussels to the eggs, larvae, and cuticular remnants of U. tetrafurcatus were also studied. Therefore, the present study demonstrated that freshwater bivalves have a new host and locality records for infection with U. tetrafurcatus. Future studies are recommended to include advanced molecular characteristics for these mites. PMID- 29590002 TI - Low-dose cadmium exposure exacerbates polyhexamethylene guanidine-induced lung fibrosis in mice. AB - Cadmium (Cd) is a toxic metal present in tobacco smoke, air, food, and water. Inhalation is an important route of Cd exposure, and lungs are one of the main target organs for metal-induced toxicity. Cd inhalation is associated with an increased risk of pulmonary diseases. The present study aimed to assess the effects of repeated exposure to low-dose Cd in a mouse model of polyhexamethylene guanidine (PHMG)-induced lung fibrosis. Mice were grouped into the following groups: vehicle control (VC), PHMG, cadmium chloride (CdCl2), and PHMG + CdCl2. Animals in the PHMG group exhibited increased numbers of total cells and inflammatory cells in the bronchoalveolar lavage fluid (BALF) accompanied by inflammation and fibrosis in lung tissues. These parameters were exacerbated in mice in the PHMG + CdCl2 group. In contrast, mice in the CdCl2 group alone displayed only minimal inflammation in pulmonary tissue. Expression of inflammatory cytokines and fibrogenic mediators was significantly elevated in lungs of mice in the PHMG group compared with that VC. Further, expression of these cytokines and mediators was enhanced in pulmonary tissue in mice administered PHMG + CdCl2. Data demonstrate that repeated exposure to low-dose Cd may enhance the development of PHMG-induced pulmonary fibrosis. PMID- 29590004 TI - Molecular Mechanisms of Colistin Resistance Among Pandrug-Resistant Isolates of Acinetobacter baumannii with High Case-Fatality Rate in Intensive Care Unit Patients. AB - Colistin is considered a last-hope antibiotic against extensively drug-resistant isolates of Acinetobacter baumannii. Resistance to colistin has been rarely reported for A. baumannii. Genetic alterations in the PmrA-PmrB two-component system and lipid A biosynthesis genes may be associated with colistin resistance. We investigated molecular mechanisms of colistin resistance in three clinical colistin-resistant (ColR) and two colistin-susceptible (ColS) A. baumannii isolates. A ColR mutant was generated in vitro by repetitive drug exposure. The pmrA, pmrB, lpxA, lpxC, and lpxD genes were amplified and sequenced. To evaluate association between colistin resistance and upregulation of pmrCAB operon, transcriptional level of the pmrC gene encoding for lipid A phosphoethanolamine (PEtN) transferase was quantified by reverse transcription quantitative PCR (RT qPCR) analysis. All clinical and in vitro-selected ColR isolates harbored at least one point mutation in the pmrB gene, including A142V, P233S, T235I, and A227V substitutions as well as duplication of H325. No alteration was found in the pmrA and other amino acid substitutions identified in the pmrB as well as lpx genes did not seem to be involved in colistin resistance as they were found in both ColS and ColR isolates. RT-qPCR analysis revealed a correlation between colistin resistance and pmrC overexpression. Specific alterations in the PmrB, linked to overproduction of PEtN transferase, triggered colistin resistance in the studied A. baumannii isolates. PMID- 29590003 TI - Lack of efficacy of transgenic pea (Pisum sativum L.) stably expressing antifungal genes against Fusarium spp. in three years of confined field trials. AB - Fusarium root rot is a major pea disease in Canada and only partial tolerance exists in germplasm. Transgenic technologies may hold promise but the economic benefits of genetically modified (GM) pea will need to surpass the regulatory costs, time and labor involved in bringing a GM crop to market. European pea (Pisum sativum L.) cultivars expressing four antifungal genes, 1-3 beta glucanase (G), endochitinase (C) (belonging to PR proteins family), polygalacturonase inhibiting proteins (PGIPs) (P) and stilbene synthase (V) have been transformed for disease tolerance and showed disease tolerance under laboratory conditions. Transgenic lines with four antifungal genes inserted either individually or stacked through crossing were tested for their efficacy against Fusarium root rot (Fusarium avenaceum) in confined trials over three years (2013 to 2015) in comparison with two parental German lines and three Canadian lines. Superior emergence, higher fresh weight or lower disease ratings above and below ground, of transgenic lines in presence of disease inoculum were not observed consistently in the three years of field experiments when compared to the parental and Canadian lines in the presence of disease inoculum. No indication of an advantage of stacked genes over single genes was observed. Most transgenic lines had lower relative gene expression in the roots than in the leaves in greenhouse trials suggesting a possible explanation for poor tolerance to Fusarium root rot. Field trials are necessary to verify the agronomic performance and ecological relevance of the promising effects detected under laboratory conditions. PMID- 29590005 TI - Religious People Are Trusted Because They Are Viewed as Slow Life-History Strategists. AB - Religious people are more trusted than nonreligious people. Although most theorists attribute these perceptions to the beliefs of religious targets, religious individuals also differ in behavioral ways that might cue trust. We examined whether perceivers might trust religious targets more because they heuristically associate religion with slow life-history strategies. In three experiments, we found that religious targets are viewed as slow life-history strategists and that these findings are not the result of a universally positive halo effect; that the effect of target religion on trust is significantly mediated by the target's life-history traits (i.e., perceived reproductive strategy); and that when perceivers have direct information about a target's reproductive strategy, their ratings of trust are driven primarily by his or her reproductive strategy, rather than religion. These effects operate over and above targets' belief in moralizing gods and offer a novel theoretical perspective on religion and trust. PMID- 29590006 TI - Low-Fat Abiraterone Food Effect Is of Little Consequence. PMID- 29590007 TI - Prospective International Randomized Phase II Study of Low-Dose Abiraterone With Food Versus Standard Dose Abiraterone In Castration-Resistant Prostate Cancer. AB - Purpose Abiraterone acetate (AA) is a standard of care for metastatic castration resistant prostate cancer (CRPC). Despite a large food effect, AA was administered under fasting conditions in its pivotal trials. We sought to test the hypothesis that low-dose AA (LOW; 250 mg with a low-fat meal) would have comparable activity to standard AA (STD; 1,000 mg fasting) in patients with CRPC. Patients and Methods Patients (n = 72) with progressive CRPC from seven institutions in the United States and Singapore were randomly assigned to STD or LOW. Both arms received prednisone 5 mg twice daily. Prostate-specific antigen (PSA) was assessed monthly, and testosterone/dehydroepiandrosterone sulfate were assessed every 12 weeks with disease burden radiographic assessments. Plasma was collected for drug concentrations. Log change in PSA, as a pharmacodynamic biomarker for efficacy, was the primary end point, using a noninferiority design. Progression-free survival (PFS), PSA response (>= 50% reduction), change in androgen levels, and pharmacokinetics were secondary end points. Results Thirty six patients were accrued to both arms. At 12 weeks, there was a greater effect on PSA in the LOW arm (mean log change, -1.59) compared with STD (-1.19), and noninferiority of LOW was established according to predefined criteria. The PSA response rate was 58% in LOW and 50% in STD, and the median PFS was approximately 9 months in both groups. Androgen levels decreased similarly in both arms. Although there was no difference in PSA response or PFS, abiraterone concentrations were higher in STD. Conclusion Low-dose AA (with low-fat breakfast) is noninferior to standard dosing with respect to PSA metrics. Given the pharmacoeconomic implications, these data warrant consideration by prescribers, payers, and patients. Additional studies are indicated to assess the long-term efficacy of this approach. PMID- 29590008 TI - Health-Related Quality-of-Life Analysis From KEYNOTE-045: A Phase III Study of Pembrolizumab Versus Chemotherapy for Previously Treated Advanced Urothelial Cancer. AB - Purpose In the phase III KEYNOTE-045 study ( ClinicalTrials.gov identifier: NCT02256436), pembrolizumab significantly prolonged overall survival compared with investigator's choice of chemotherapy in patients with previously treated advanced urothelial cancer. Here, we report the results of health-related quality of-life (HRQoL) analyses from the KEYNOTE-045 trial. Patients and Methods Patients were randomly assigned 1:1 to pembrolizumab 200 mg or investigator's choice of docetaxel 75 mg/m2, paclitaxel 175 mg/m2, or vinflunine 320 mg/m2 administered intravenously every 3 weeks. Key prespecified HRQoL analyses were time to deterioration (TTD) and mean change from baseline to week 15 in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 global health status/quality-of-life score. Results Of 542 patients who were randomly assigned, 519 were included in HRQoL analyses (pembrolizumab, n = 266; chemotherapy, n = 253). HRQoL compliance was > 95% at baseline and approximately 88% at week 15 for both groups. Pembrolizumab prolonged TTD in global health status/quality-of-life score compared with chemotherapy (median, 3.5 months v 2.3 months; hazard ratio, 0.72; nominal one-sided P = .004). Mean (95% CI) change from baseline to week 15 in global health status/quality-of-life score was 0.69 ( 2.40 to 3.77) with pembrolizumab and -8.36 (-11.84 to -4.89) with chemotherapy (mean difference, 9.05 points; 95% CI, 4.61 to 13.50; nominal two-sided P < .001). Conclusion Pembrolizumab prolonged TTD in HRQoL compared with chemotherapy. Patients who were treated with pembrolizumab had stable or improved global health status/quality of life, whereas those who were treated with investigator's choice of chemotherapy experienced declines in global health status/quality of life. Combined with efficacy and safety outcomes, these data support pembrolizumab as standard of care for patients with platinum-refractory advanced urothelial cancer.

AB - Proximity, or the physical closeness of molecules, is a pervasive regulatory mechanism in biology. For example, most posttranslational modifications such as phosphorylation, methylation, and acetylation promote proximity of molecules to play deterministic roles in cellular processes. To understand the role of proximity in biologic mechanisms, chemical inducers of proximity (CIPs) were developed to synthetically model biologically regulated recruitment. Chemically induced proximity allows for precise temporal control of transcription, signaling cascades, chromatin regulation, protein folding, localization, and degradation, as well as a host of other biologic processes. A systematic analysis of CIPs in basic research, coupled with recent technological advances utilizing CRISPR, distinguishes roles of causality from coincidence and allows for mathematical modeling in synthetic biology. Recently, induced proximity has provided new avenues of gene therapy and emerging advances in cancer treatment.

AB - Rosas et al (Reports, 22 September 2017, p. 1282) calculate El Sidron J1 to have reached only 87.5% of its adult brain size. This finding is based on an overestimation of Neandertal brain size. Pairwise comparisons with a larger sample of Neandertal fossils reveal that it is unlikely that the brain of El Sidron would have grown appreciably larger. PMID- 29590010 TI - Mapping mutational effects along the evolutionary landscape of HIV envelope. AB - The immediate evolutionary space accessible to HIV is largely determined by how single amino acid mutations affect fitness. These mutational effects can shift as the virus evolves. However, the prevalence of such shifts in mutational effects remains unclear. Here, we quantify the effects on viral growth of all amino acid mutations to two HIV envelope (Env) proteins that differ at [Formula: see text]100 residues. Most mutations similarly affect both Envs, but the amino acid preferences of a minority of sites have clearly shifted. These shifted sites usually prefer a specific amino acid in one Env, but tolerate many amino acids in the other. Surprisingly, shifts are only slightly enriched at sites that have substituted between the Envs-and many occur at residues that do not even contact substitutions. Therefore, long-range epistasis can unpredictably shift Env's mutational tolerance during HIV evolution, although the amino acid preferences of most sites are conserved between moderately diverged viral strains.

AB - The comment by DeSilva challenges our suggestion that brain growth of the El Sidron J1 Neandertal was still incomplete at 7.7 years of age. Evidence suggests that endocranial volume is likely to represent less than 90% adult size at El Sidron as well as Neandertal male plus Krapina samples, in line with further evidence from endocranial surface histology and dural sinus groove size.

AB - Simulations and theory suggest that the thermodynamic anomalies of water may be related to a phase transition between two supercooled liquid states, but so far this phase transition has not been observed experimentally because of preemptive ice crystallization. We used calorimetry, infrared spectroscopy, and molecular dynamics simulations to investigate a water-rich hydrazinium trifluoroacetate solution in which the local hydrogen bond structure surrounding a water molecule resembles that in neat water at elevated pressure, but which does not crystallize upon cooling. Instead, this solution underwent a sharp, reversible phase transition between two homogeneous liquid states. The hydrogen-bond structures of these two states are similar to those established for high- and low-density amorphous (HDA and LDA) water. Such structural similarity supports theories that predict a similar sharp transition in pure water under pressure if ice crystallization could be suppressed. PMID- 29590041 TI - Coherent, atomically thin transition-metal dichalcogenide superlattices with engineered strain. AB - Epitaxy forms the basis of modern electronics and optoelectronics. We report coherent atomically thin superlattices in which different transition metal dichalcogenide monolayers-despite large lattice mismatches-are repeated and laterally integrated without dislocations within the monolayer plane. Grown by an omnidirectional epitaxy, these superlattices display fully matched lattice constants across heterointerfaces while maintaining an isotropic lattice structure and triangular symmetry. This strong epitaxial strain is precisely engineered via the nanoscale supercell dimensions, thereby enabling broad tuning of the optical properties and producing photoluminescence peak shifts as large as 250 millielectron volts. We present theoretical models to explain this coherent growth and the energetic interplay governing the ripple formation in these strained monolayers. Such coherent superlattices provide building blocks with targeted functionalities at the atomically thin limit.

AB - Water-rich regions in Earth's deeper mantle are suspected to play a key role in the global water budget and the mobility of heat-generating elements. We show that ice-VII occurs as inclusions in natural diamond and serves as an indicator for such water-rich regions. Ice-VII, the residue of aqueous fluid present during growth of diamond, crystallizes upon ascent of the host diamonds but remains at pressures as high as 24 gigapascals; it is now recognized as a mineral by the International Mineralogical Association. In particular, ice-VII in diamonds points toward fluid-rich locations in the upper transition zone and around the 660-kilometer boundary. PMID- 29590043 TI - Sustained climate warming drives declining marine biological productivity. AB - Climate change projections to the year 2100 may miss physical-biogeochemical feedbacks that emerge later from the cumulative effects of climate warming. In a coupled climate simulation to the year 2300, the westerly winds strengthen and shift poleward, surface waters warm, and sea ice disappears, leading to intense nutrient trapping in the Southern Ocean. The trapping drives a global-scale nutrient redistribution, with net transfer to the deep ocean. Ensuing surface nutrient reductions north of 30 degrees S drive steady declines in primary production and carbon export (decreases of 24 and 41%, respectively, by 2300). Potential fishery yields, constrained by lower-trophic-level productivity, decrease by more than 20% globally and by nearly 60% in the North Atlantic. Continued high levels of greenhouse gas emissions could suppress marine biological productivity for a millennium. PMID- 29590044 TI - Local transformations of the hippocampal cognitive map. AB - Grid cells are neurons active in multiple fields arranged in a hexagonal lattice and are thought to represent the "universal metric for space." However, they become nonhomogeneously distorted in polarized enclosures, which challenges this view. We found that local changes to the configuration of the enclosure induce individual grid fields to shift in a manner inversely related to their distance from the reconfigured boundary. The grid remained primarily anchored to the unchanged stable walls and showed a nonuniform rescaling. Shifts in simultaneously recorded colocalized grid fields were strongly correlated, which suggests that the readout of the animal's position might still be intact. Similar field shifts were also observed in place and boundary cells-albeit of greater magnitude and more pronounced closer to the reconfigured boundary-which suggests that there is no simple one-to-one relationship between these three different cell types. PMID- 29590045 TI - The spread of true and false news online. AB - We investigated the differential diffusion of all of the verified true and false news stories distributed on Twitter from 2006 to 2017. The data comprise ~126,000 stories tweeted by ~3 million people more than 4.5 million times. We classified news as true or false using information from six independent fact-checking organizations that exhibited 95 to 98% agreement on the classifications. Falsehood diffused significantly farther, faster, deeper, and more broadly than the truth in all categories of information, and the effects were more pronounced for false political news than for false news about terrorism, natural disasters, science, urban legends, or financial information. We found that false news was more novel than true news, which suggests that people were more likely to share novel information. Whereas false stories inspired fear, disgust, and surprise in replies, true stories inspired anticipation, sadness, joy, and trust. Contrary to conventional wisdom, robots accelerated the spread of true and false news at the same rate, implying that false news spreads more than the truth because humans, not robots, are more likely to spread it.

AB - The faithful inheritance of the epigenome is critical for cells to maintain gene expression programs and cellular identity across cell divisions. We mapped strand specific DNA methylation after replication forks and show maintenance of the vast majority of the DNA methylome within 20 minutes of replication and inheritance of some hemimethylated CpG dinucleotides (hemiCpGs). Mapping the nascent DNA methylome targeted by each of the three DNA methyltransferases (DNMTs) reveals interactions between DNMTs and substrate daughter cytosines en route to maintenance methylation or hemimethylation. Finally, we show the inheritance of hemiCpGs at short regions flanking CCCTC-binding factor (CTCF)/cohesin binding sites in pluripotent cells. Elimination of hemimethylation causes reduced frequency of chromatin interactions emanating from these sites, suggesting a role for hemimethylation as a stable epigenetic mark regulating CTCF-mediated chromatin interactions.

AB - The gut microbiota benefits humans via short-chain fatty acid (SCFA) production from carbohydrate fermentation, and deficiency in SCFA production is associated with type 2 diabetes mellitus (T2DM). We conducted a randomized clinical study of specifically designed isoenergetic diets, together with fecal shotgun metagenomics, to show that a select group of SCFA-producing strains was promoted by dietary fibers and that most other potential producers were either diminished or unchanged in patients with T2DM. When the fiber-promoted SCFA producers were present in greater diversity and abundance, participants had better improvement in hemoglobin A1c levels, partly via increased glucagon-like peptide-1 production. Promotion of these positive responders diminished producers of metabolically detrimental compounds such as indole and hydrogen sulfide. Targeted restoration of these SCFA producers may present a novel ecological approach for managing T2DM. PMID- 29590047 TI - Translocation of a gut pathobiont drives autoimmunity in mice and humans. AB - Despite multiple associations between the microbiota and immune diseases, their role in autoimmunity is poorly understood. We found that translocation of a gut pathobiont, Enterococcus gallinarum, to the liver and other systemic tissues triggers autoimmune responses in a genetic background predisposing to autoimmunity. Antibiotic treatment prevented mortality in this model, suppressed growth of E. gallinarum in tissues, and eliminated pathogenic autoantibodies and T cells. Hepatocyte-E. gallinarum cocultures induced autoimmune-promoting factors. Pathobiont translocation in monocolonized and autoimmune-prone mice induced autoantibodies and caused mortality, which could be prevented by an intramuscular vaccine targeting the pathobiont. E. gallinarum-specific DNA was recovered from liver biopsies of autoimmune patients, and cocultures with human hepatocytes replicated the murine findings; hence, similar processes apparently occur in susceptible humans. These discoveries show that a gut pathobiont can translocate and promote autoimmunity in genetically predisposed hosts.

AB - Huang and Xu argue that the cyclo-N5- ion in (N5)6(H3O)3(NH4)4Cl we described in our report is theoretically unfavorable and is instead protonated. Their conclusion is invalid, as they use an improper method to assess the proton transfer in a solid crystal structure. We present an in-depth experimental and theoretical analysis of (N5)6(H3O)3(NH4)4Cl that supports the results in the original paper.

AB - Zhang et al (Reports, 27 January 2017, p. 374) reported synthesis of a cyclo-N5- ion putatively stabilized in a solid-state salt by hydrogen bonding from surrounding counterions. We performed theoretical calculations suggesting that HN5 would be favored over the anion in the reported pentazolate salt via proton transfer. PMID- 29590052 TI - Good gun policy needs research.

AB - The successful incorporation of active proteins into synthetic polymers could lead to a new class of materials with functions found only in living systems. However, proteins rarely function under the conditions suitable for polymer processing. On the basis of an analysis of trends in protein sequences and characteristic chemical patterns on protein surfaces, we designed four-monomer random heteropolymers to mimic intrinsically disordered proteins for protein solubilization and stabilization in non-native environments. The heteropolymers, with optimized composition and statistical monomer distribution, enable cell-free synthesis of membrane proteins with proper protein folding for transport and enzyme-containing plastics for toxin bioremediation. Controlling the statistical monomer distribution in a heteropolymer, rather than the specific monomer sequence, affords a new strategy to interface with biological systems for protein based biomaterials. PMID- 29590070 TI - Phenotype risk scores identify patients with unrecognized Mendelian disease patterns. AB - Genetic association studies often examine features independently, potentially missing subpopulations with multiple phenotypes that share a single cause. We describe an approach that aggregates phenotypes on the basis of patterns described by Mendelian diseases. We mapped the clinical features of 1204 Mendelian diseases into phenotypes captured from the electronic health record (EHR) and summarized this evidence as phenotype risk scores (PheRSs). In an initial validation, PheRS distinguished cases and controls of five Mendelian diseases. Applying PheRS to 21,701 genotyped individuals uncovered 18 associations between rare variants and phenotypes consistent with Mendelian diseases. In 16 patients, the rare genetic variants were associated with severe outcomes such as organ transplants. PheRS can augment rare-variant interpretation and may identify subsets of patients with distinct genetic causes for common diseases. PMID- 29590072 TI - Real-time imaging of adatom-promoted graphene growth on nickel. AB - Single adatoms are expected to participate in many processes occurring at solid surfaces, such as the growth of graphene on metals. We demonstrate, both experimentally and theoretically, the catalytic role played by single metal adatoms during the technologically relevant process of graphene growth on nickel (Ni). The catalytic action of individual Ni atoms at the edges of a growing graphene flake was directly captured by scanning tunneling microscopy imaging at the millisecond time scale, while force field molecular dynamics and density functional theory calculations rationalize the experimental observations. Our results unveil the mechanism governing the activity of a single-atom catalyst at work. PMID- 29590073 TI - Organometallic and radical intermediates reveal mechanism of diphthamide biosynthesis. AB - Diphthamide biosynthesis involves a carbon-carbon bond-forming reaction catalyzed by a radical S-adenosylmethionine (SAM) enzyme that cleaves a carbon-sulfur (C-S) bond in SAM to generate a 3-amino-3-carboxypropyl (ACP) radical. Using rapid freezing, we have captured an organometallic intermediate with an iron-carbon (Fe C) bond between ACP and the enzyme's [4Fe-4S] cluster. In the presence of the substrate protein, elongation factor 2, this intermediate converts to an organic radical, formed by addition of the ACP radical to a histidine side chain. Crystal structures of archaeal diphthamide biosynthetic radical SAM enzymes reveal that the carbon of the SAM C-S bond being cleaved is positioned near the unique cluster Fe, able to react with the cluster. Our results explain how selective C-S bond cleavage is achieved in this radical SAM enzyme. PMID- 29590074 TI - Protecting marine mammals, turtles, and birds by rebuilding global fisheries. AB - Reductions in global fishing pressure are needed to end overfishing of target species and maximize the value of fisheries. We ask whether such reductions would also be sufficient to protect non-target species threatened as bycatch. We compare changes in fishing pressure needed to maximize profits from 4713 target fish stocks-accounting for >75% of global catch-to changes in fishing pressure needed to reverse ongoing declines of 20 marine mammal, sea turtle, and seabird populations threatened as bycatch. We project that maximizing fishery profits would halt or reverse declines of approximately half of these threatened populations. Recovering the other populations would require substantially greater effort reductions or targeting improvements. Improving commercial fishery management could thus yield important collateral benefits for threatened bycatch species globally. PMID- 29590076 TI - Precursors of logical reasoning in preverbal human infants. AB - Infants are able to entertain hypotheses about complex events and to modify them rationally when faced with inconsistent evidence. These capacities suggest that infants can use elementary logical representations to frame and prune hypotheses. By presenting scenes containing ambiguities about the identity of an object, here we show that 12- and 19-month-old infants look longer at outcomes that are inconsistent with a logical inference necessary to resolve such ambiguities. At the moment of a potential deduction, infants' pupils dilated, and their eyes moved toward the ambiguous object when inferences could be computed, in contrast to transparent scenes not requiring inferences to identify the object. These oculomotor markers resembled those of adults inspecting similar scenes, suggesting that intuitive and stable logical structures involved in the interpretation of dynamic scenes may be part of the fabric of the human mind. PMID- 29590077 TI - Factoring stream turbulence into global assessments of nitrogen pollution. AB - The discharge of excess nitrogen to streams and rivers poses an existential threat to both humans and ecosystems. A seminal study of headwater streams across the United States concluded that in-stream removal of nitrate is controlled primarily by stream chemistry and biology. Reanalysis of these data reveals that stream turbulence (in particular, turbulent mass transfer across the concentration boundary layer) imposes a previously unrecognized upper limit on the rate at which nitrate is removed from streams. The upper limit closely approximates measured nitrate removal rates in streams with low concentrations of this pollutant, a discovery that should inform stream restoration designs and efforts to assess the effects of nitrogen pollution on receiving water quality and the global nitrogen cycle. PMID- 29590075 TI - GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencing. AB - Malaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector and transmit malaria. Sexual commitment is triggered by activation of AP2-G, the master transcriptional regulator of gametocytogenesis. Heterochromatin protein 1 (HP1)-dependent silencing of ap2-g prevents sexual conversion in proliferating parasites. In this study, we identified Plasmodium falciparum gametocyte development 1 (GDV1) as an upstream activator of sexual commitment. We found that GDV1 targeted heterochromatin and triggered HP1 eviction, thus derepressing ap2-g Expression of GDV1 was responsive to environmental triggers of sexual conversion and controlled via a gdv1 antisense RNA. Hence, GDV1 appears to act as an effector protein that induces sexual differentiation by antagonizing HP1-dependent gene silencing. PMID- 29590078 TI - Lysosome activation clears aggregates and enhances quiescent neural stem cell activation during aging. AB - In the adult brain, the neural stem cell (NSC) pool comprises quiescent and activated populations with distinct roles. Transcriptomic analysis revealed that quiescent and activated NSCs exhibited differences in their protein homeostasis network. Whereas activated NSCs had active proteasomes, quiescent NSCs contained large lysosomes. Quiescent NSCs from young mice accumulated protein aggregates, and many of these aggregates were stored in large lysosomes. Perturbation of lysosomal activity in quiescent NSCs affected protein-aggregate accumulation and the ability of quiescent NSCs to activate. During aging, quiescent NSCs displayed defects in their lysosomes, increased accumulation of protein aggregates, and reduced ability to activate. Enhancement of the lysosome pathway in old quiescent NSCs cleared protein aggregates and ameliorated the ability of quiescent NSCs to activate, allowing them to regain a more youthful state. PMID- 29590079 TI - Mutation dynamics and fitness effects followed in single cells. AB - Mutations have been investigated for more than a century but remain difficult to observe directly in single cells, which limits the characterization of their dynamics and fitness effects. By combining microfluidics, time-lapse imaging, and a fluorescent tag of the mismatch repair system in Escherichia coli, we visualized the emergence of mutations in single cells, revealing Poissonian dynamics. Concomitantly, we tracked the growth and life span of single cells, accumulating ~20,000 mutations genome-wide over hundreds of generations. This analysis revealed that 1% of mutations were lethal; nonlethal mutations displayed a heavy-tailed distribution of fitness effects and were dominated by quasi neutral mutations with an average cost of 0.3%. Our approach has enabled the investigation of single-cell individuality in mutation rate, mutation fitness costs, and mutation interactions. PMID- 29590080 TI - Instagram won't solve inequality.

AB - Background Adolescence is one of the critical periods where increased risk for long-term obesity-related complications is an important health concern. This highlights the need to perform early diagnostics based on precise biomarkers to decrease the risk of complications in adolescents with obesity. Objective To determine the relationships between serum levels of uric acid (UA), leptin and insulin with metabolic syndrome (MS) components in Algerian adolescents. Subjects Nondiabetic adolescents (n = 204). Methods Blood pressure (BP) and anthropometric measurements were performed using standardized techniques. Blood samples were taken for determination of glycemia, triglyceridemia, uricemia, cholesterolemia, leptinemia and insulinemia. Results The rate of MS among an excess weight group was 17.4% [95% confidence interval (CI)]. Serum levels of UA, leptin and insulin were significantly higher in the excess weight group compared to a normal weight group (279.4 +/- 86.05 vs. 204.9 +/- 50.34 MUmol/L and 25.65 +/- 14.01 vs. 4.09 +/- 2.60 MUg/L, p < 0.001; 24.58 +/- 13.85 vs. 13.34 +/- 6.41 MUIU/L, p < 0.05). Serum levels of UA, leptin and insulin were significantly higher in adolescents with MS compared to those without MS (304.86 +/- 111.41 vs. 224.72 +/- 77.81 MUmol/L, 30.26 +/- 12.46 vs. 16.93 +/- 14.97 MUg/L and 30.91 +/- 17.30 vs. 18.71 +/- 10.14 MUIU/L, p < 0.05, respectively). Significant correlations were found between UA and leptin with waist circumference (r = 0.50 and 0.76), diastolic blood pressure (r = 0.58 and 0.43), triglycerides (r = 0.42 and 0.35) and high density lipoprotein-cholesterol (r = -0.36 and -0.35). Conclusion Serum levels of UA and leptin may be useful biomarkers for early diagnosis of the risk of MS in our Algerian adolescent population.

AB - INTRODUCTION: Combinations of gefitinib and radiotherapy have been observed to have synergistic and anti-proliferative effects on lung cancer in vitro. In the clinical setting, patients who presented with respiratory difficulties such as superior vena cava syndrome (SVCS), radiotherapy should be given immediately to address the emergency while waiting for the results of epidermal growth factor receptor (EGFR) mutation test. However, there has been no study that described the role of radio-therapy in Indonesian patients with EGFR-mutant lung adenocarcinoma. METHODS: This preliminary study aimed to evaluate the efficacy and toxicities of gefitinib and radiotherapy combination in lung adenocarcinoma patients in Persahabatan National Respiratory Referral Hospital, Jakarta, Indonesia. Subjects were consecutively recruited between January 2013 and December 2016. RESULTS: Thirty-one lung adenocarcinoma with EGFR mutations were enrolled. Most of them were male (51.61%) with a median age of 54.5 years old (range 38-70 years old). EGFR mutation characteristics were on exon 21 L858R point mutation (61.30%), exon 21 L861Q point mutation (16.12%) and exon 19 deletion (22.58%). Radiotherapy was given at doses between 30-60 Gy. Among these subjects, median progression-free survival (PFS) was 185 days (95%CI; 123.69 - 246.30), 1-year survival rate (1-yr) was 45.2%, and median overall survival (OS) was 300 days (95%CI; 130.94 - 469.06). There were no grade 3/4 hematological and nonhematological toxicities recorded. The most frequent grade 1 and 2 non hematological toxicities were skin rash, diarrhea, and paronychia that might be related to tyrosine kinase inhibitor (TKI). CONCLUSION: The combination of TKI with radiation may be considered in EGFR-mutant lung adenocarcinoma subjects. PMID- 29590084 TI - Antibacterial secotirucallane triterpenes from the stem bark of Pseudocedrela kotschyi. AB - The antibacterial-guided investigation of the stem bark extract of Pseudocedrela kotschyi led to the isolation of a new secotirucallane triterpene derivative: 4 hydroxy-3,4-secotirucalla-7,24-dien-3,21-dioic acid (1), together with the known one: 3,4-secotirucalla-4(28),7,24-trien-3,21-dioic acid (2) and 3-methyl ester 3,4-secotirucalla-4(28),7,24-trien-3,21-dioic (3). The structures of the isolated compounds were elucidated on the basis of extensive 1D- and 2D-NMR spectroscopy. Extracts, fractions and compounds (1-3) were tested in vitro for antibacterial activity against two Gram positive bacteria (Bacillus subtilis and Staphylococcus aureus ATCC 25923), and two Gram negative bacteria (Escherichia coli S2(1) and Pseudomonas aeruginosa). The MeOH extract and the Hex/CH2Cl2 (70:30) fraction showed significant levels of activity (MIC=64- 256 MUg/mL) compared with the two reference drugs [ciprofloxacin: MIC (0.5-1 MUg/mL) and amoxicillin: MIC (1-128 MUg/mL)]. Moreover, the compound 2 isolated from this Hex/CH2Cl2 (70:30) fraction had the greatest potential value against S. aureus, E. coli and P. aeruginosa, with minimum inhibitory concentrations (MIC) ranging from 4-16 MUg/mL. PMID- 29590085 TI - Factors affecting mortality in elderly patients who underwent surgery for gastric cancer. AB - AIM: The aim of this study was to determine factors affecting overall mortality in patients over 60 years of age who underwent surgery for gastric cancer in our clinic. MATERIAL AND METHODS: Data on histopathological diagnosis (tumor size, lymph node status, and number), pathological stage, serum albumin level, tumor markers, complete blood count, and demographic information of 109 patients over 60 years of age who had surgery for gastric cancer between January 2011 and July 2016 were obtained retrospectively from the patient files. In addition, the survival status of all patients were examined and recorded. Metastatic lymph node ratio (MLR), red cell distribution width platelet ratio (RPR), neutrophil lymphocyte ratio (NLR), plateletlymphocyte ratio (PLR), and prognostic nutritional index (PNI) were calculated. RESULTS: On univariate analysis of independent parameters, pathological LN number (p = 0.001), MLR (p <0.001), T3 (p = 0.001) or T4 (p = 0,006) tumor stage according to TNM system, the presence of metastasis (p = 0.063), and male gender (p = 0.066) were found to affect overall mortality (OM). On multivariable Cox regression analysis of these results, MLR (p = 0.005) and T stage (p = 0.006) was determined to be a statistically significant and independent prognostic value. CONCLUSION: In patients over 60 years of age who underwent surgery for gastric cancer, the factors affecting mortality were determined to be the presence of metastases, number of pathological lymph nodes, and male gender. Metastatic lymph node ratio and T1&T2 stage were determined to be independent prognostic factors. KEY WORDS: Elderly, Gastric cancer, Mortality, Prognostic factor. PMID- 29590086 TI - Presence of Spotters Improves Bench Press Performance: A Deception Study. AB - Sheridan, A, Marchant, DC, Williams, EL, Jones, HS, Hewitt, PA, and Sparks, SA. Presence of spotters improves bench press performance: a deception study. J Strength Cond Res XX(X): 000-000, 2017-Resistance exercise is a widely used method of physical training in both recreational exercise and athletic populations. The use of training partners and spotters during resistance exercise is widespread, but little is known about the effect of the presence of these individuals on exercise performance. The purpose of the current study was to investigate the effect of spotter presence on bench press performance. Twelve recreationally trained participants (age, 21.3 +/- 0.8 years, height, 1.82 +/- 0.1 m, and weight, 84.8 +/- 11.1 kg) performed 2 trials of 3 sets to failure at 60% of 1 repetition maximum on separate occasions. The 2 trials consisted of spotters being explicitly present or hidden from view (deception). During the trials, total repetitions (reps), total weight lifted, ratings of perceived exertion (RPE), and self-efficacy were measured. Total reps and weight lifted were significantly greater with spotters (difference = 4.5 reps, t = 5.68, p < 0.001 and difference = 209.6 kg, t = 5.65, p < 0.001, respectively). Although RPE and local RPE were significantly elevated in the deception trials (difference = 0.78, f = 6.16, p = 0.030 and difference = 0.81, f = 5.89, p = 0.034, respectively), self-efficacy was significantly reduced (difference = 1.58, f = 26.90, p < 0.001). This study demonstrates that resistance exercise is improved by the presence of spotters, which is facilitated by reduced RPE and increased self-efficacy. This has important implications for athletes and clients, who should perform resistance exercise in the proximity of others, to maximize total work performed. PMID- 29590087 TI - MicroRNA Expression Profiling of Bone Marrow Mesenchymal Stem Cells in Steroid Induced Osteonecrosis of the Femoral Head Associated with Osteogenesis. AB - BACKGROUND Steroid-induced osteonecrosis of the femoral head (SONFH) is a common orthopedic disease associated with the application of glucocorticoid (GC). In this study, we detected the microRNAs (miRNAs) differentially expressed in bone marrow mesenchymal stem cells (BMSCs) from SONFH patients, and target gene predictions were performed, and the functions of the target genes was verified. MATERIAL AND METHODS BMSCs collected from patients with SONFH and femoral neck fracture (FNF) constituted the SONFH group (n=3) and FNF (control) group (n=3), respectively. MiRNA microarray analysis was utilized to detect the differentially expressed miRNAs, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to verify the microarray results. The target genes and functions of the differentially expressed miRNAs were analyzed using a bioinformatics database. RESULTS The microarray results revealed that compared with the control group, 22 miRNAs were identified differentially expressed in the SONFH group, with 17 upregulated and 5 downregulated. Further qRT-PCR validation of differentially expressed miRNAs confirmed that hsa-miR-601, hsa-miR-452-3p, hsa-miR-647, and hsa miR-516b-5p were significantly increased, whereas hsa-miR-122-3p was significantly decreased. During osteogenic differentiation, hsa-miR-601, hsa-miR 452-3p, hsa-miR-647, hsa-miR-516b-5p, and hsa-miR-127-5p were significantly downregulated, whereas hsa-miR-122-3p was significantly upregulated, and miRNAs showed a converse tendency during adipogenic differentiation. CONCLUSIONS Six miRNAs associated with osteogenic and adipogenic differentiation were identified differentially expressed in the BMSCs of SONFH patients; these miRNAs may serve as novel biomarkers or therapeutic targets for SONFH. PMID- 29590088 TI - Structure of the peptidoglycan polymerase RodA resolved by evolutionary coupling analysis. AB - The shape, elongation, division and sporulation (SEDS) proteins are a large family of ubiquitous and essential transmembrane enzymes with critical roles in bacterial cell wall biology. The exact function of SEDS proteins was for a long time poorly understood, but recent work has revealed that the prototypical SEDS family member RodA is a peptidoglycan polymerase-a role previously attributed exclusively to members of the penicillin-binding protein family. This discovery has made RodA and other SEDS proteins promising targets for the development of next-generation antibiotics. However, little is known regarding the molecular basis of SEDS activity, and no structural data are available for RodA or any homologue thereof. Here we report the crystal structure of Thermus thermophilus RodA at a resolution of 2.9 A, determined using evolutionary covariance-based fold prediction to enable molecular replacement. The structure reveals a ten-pass transmembrane fold with large extracellular loops, one of which is partially disordered. The protein contains a highly conserved cavity in the transmembrane domain, reminiscent of ligand-binding sites in transmembrane receptors. Mutagenesis experiments in Bacillus subtilis and Escherichia coli show that perturbation of this cavity abolishes RodA function both in vitro and in vivo, indicating that this cavity is catalytically essential. These results provide a framework for understanding bacterial cell wall synthesis and SEDS protein function. PMID- 29590089 TI - Whole-organism clone tracing using single-cell sequencing. AB - Embryonic development is a crucial period in the life of a multicellular organism, during which limited sets of embryonic progenitors produce all cells in the adult body. Determining which fate these progenitors acquire in adult tissues requires the simultaneous measurement of clonal history and cell identity at single-cell resolution, which has been a major challenge. Clonal history has traditionally been investigated by microscopically tracking cells during development, monitoring the heritable expression of genetically encoded fluorescent proteins and, more recently, using next-generation sequencing technologies that exploit somatic mutations, microsatellite instability, transposon tagging, viral barcoding, CRISPR-Cas9 genome editing and Cre-loxP recombination. Single-cell transcriptomics provides a powerful platform for unbiased cell-type classification. Here we present ScarTrace, a single-cell sequencing strategy that enables the simultaneous quantification of clonal history and cell type for thousands of cells obtained from different organs of the adult zebrafish. Using ScarTrace, we show that a small set of multipotent embryonic progenitors generate all haematopoietic cells in the kidney marrow, and that many progenitors produce specific cell types in the eyes and brain. In addition, we study when embryonic progenitors commit to the left or right eye. ScarTrace reveals that epidermal and mesenchymal cells in the caudal fin arise from the same progenitors, and that osteoblast-restricted precursors can produce mesenchymal cells during regeneration. Furthermore, we identify resident immune cells in the fin with a distinct clonal origin from other blood cell types. We envision that similar approaches will have major applications in other experimental systems, in which the matching of embryonic clonal origin to adult cell type will ultimately allow reconstruction of how the adult body is built from a single cell. PMID- 29590090 TI - Architecture of the human GATOR1 and GATOR1-Rag GTPases complexes. AB - Nutrients, such as amino acids and glucose, signal through the Rag GTPases to activate mTORC1. The GATOR1 protein complex-comprising DEPDC5, NPRL2 and NPRL3 regulates the Rag GTPases as a GTPase-activating protein (GAP) for RAGA; loss of GATOR1 desensitizes mTORC1 signalling to nutrient starvation. GATOR1 components have no sequence homology to other proteins, so the function of GATOR1 at the molecular level is currently unknown. Here we used cryo-electron microscopy to solve structures of GATOR1 and GATOR1-Rag GTPases complexes. GATOR1 adopts an extended architecture with a cavity in the middle; NPRL2 links DEPDC5 and NPRL3, and DEPDC5 contacts the Rag GTPase heterodimer. Biochemical analyses reveal that our GATOR1-Rag GTPases structure is inhibitory, and that at least two binding modes must exist between the Rag GTPases and GATOR1. Direct interaction of DEPDC5 with RAGA inhibits GATOR1-mediated stimulation of GTP hydrolysis by RAGA, whereas weaker interactions between the NPRL2-NPRL3 heterodimer and RAGA execute GAP activity. These data reveal the structure of a component of the nutrient-sensing mTORC1 pathway and a non-canonical interaction between a GAP and its substrate GTPase. PMID- 29590091 TI - A new class of synthetic retinoid antibiotics effective against bacterial persisters. AB - A challenge in the treatment of Staphylococcus aureus infections is the high prevalence of methicillin-resistant S. aureus (MRSA) strains and the formation of non-growing, dormant 'persister' subpopulations that exhibit high levels of tolerance to antibiotics and have a role in chronic or recurrent infections. As conventional antibiotics are not effective in the treatment of infections caused by such bacteria, novel antibacterial therapeutics are urgently required. Here we used a Caenorhabditis elegans-MRSA infection screen to identify two synthetic retinoids, CD437 and CD1530, which kill both growing and persister MRSA cells by disrupting lipid bilayers. CD437 and CD1530 exhibit high killing rates, synergism with gentamicin, and a low probability of resistance selection. All-atom molecular dynamics simulations demonstrated that the ability of retinoids to penetrate and embed in lipid bilayers correlates with their bactericidal ability. An analogue of CD437 was found to retain anti-persister activity and show an improved cytotoxicity profile. Both CD437 and this analogue, alone or in combination with gentamicin, exhibit considerable efficacy in a mouse model of chronic MRSA infection. With further development and optimization, synthetic retinoids have the potential to become a new class of antimicrobials for the treatment of Gram-positive bacterial infections that are currently difficult to cure. PMID- 29590092 TI - Itaconate is an anti-inflammatory metabolite that activates Nrf2 via alkylation of KEAP1. AB - The endogenous metabolite itaconate has recently emerged as a regulator of macrophage function, but its precise mechanism of action remains poorly understood. Here we show that itaconate is required for the activation of the anti-inflammatory transcription factor Nrf2 (also known as NFE2L2) by lipopolysaccharide in mouse and human macrophages. We find that itaconate directly modifies proteins via alkylation of cysteine residues. Itaconate alkylates cysteine residues 151, 257, 288, 273 and 297 on the protein KEAP1, enabling Nrf2 to increase the expression of downstream genes with anti-oxidant and anti-inflammatory capacities. The activation of Nrf2 is required for the anti inflammatory action of itaconate. We describe the use of a new cell-permeable itaconate derivative, 4-octyl itaconate, which is protective against lipopolysaccharide-induced lethality in vivo and decreases cytokine production. We show that type I interferons boost the expression of Irg1 (also known as Acod1) and itaconate production. Furthermore, we find that itaconate production limits the type I interferon response, indicating a negative feedback loop that involves interferons and itaconate. Our findings demonstrate that itaconate is a crucial anti-inflammatory metabolite that acts via Nrf2 to limit inflammation and modulate type I interferons.

AB - Neocortical areas communicate through extensive axonal projections, but the logic of information transfer remains poorly understood, because the projections of individual neurons have not been systematically characterized. It is not known whether individual neurons send projections only to single cortical areas or distribute signals across multiple targets. Here we determine the projection patterns of 591 individual neurons in the mouse primary visual cortex using whole brain fluorescence-based axonal tracing and high-throughput DNA sequencing of genetically barcoded neurons (MAPseq). Projections were highly diverse and divergent, collectively targeting at least 18 cortical and subcortical areas. Most neurons targeted multiple cortical areas, often in non-random combinations, suggesting that sub-classes of intracortical projection neurons exist. Our results indicate that the dominant mode of intracortical information transfer is not based on 'one neuron-one target area' mapping. Instead, signals carried by individual cortical neurons are shared across subsets of target areas, and thus concurrently contribute to multiple functional pathways.

Tunnelling spectroscopy in electrical transport is the primary tool for identifying the presence of Majorana zero-modes, for instance as a zero-bias peak in differential conductance. The height of the Majorana zero-bias peak is predicted to be quantized at the universal conductance value of 2e2/h at zero temperature (where e is the charge of an electron and h is the Planck constant), as a direct consequence of the famous Majorana symmetry in which a particle is its own antiparticle. The Majorana symmetry protects the quantization against disorder, interactions and variations in the tunnel coupling. Previous experiments, however, have mostly shown zero-bias peaks much smaller than 2e2/h, with a recent observation of a peak height close to 2e2/h. Here we report a quantized conductance plateau at 2e2/h in the zero-bias conductance measured in indium antimonide semiconductor nanowires covered with an aluminium superconducting shell. The height of our zero-bias peak remains constant despite changing parameters such as the magnetic field and tunnel coupling, indicating that it is a quantized conductance plateau. We distinguish this quantized Majorana peak from possible non-Majorana origins by investigating its robustness to electric and magnetic fields as well as its temperature dependence. The observation of a quantized conductance plateau strongly supports the existence of Majorana zero-modes in the system, consequently paving the way for future braiding experiments that could lead to topological quantum computing. PMID- 29590095 TI - Astrocytic Kir4.1 channels and gap junctions account for spontaneous epileptic seizure. AB - Experimental recordings in hippocampal slices indicate that astrocytic dysfunction may cause neuronal hyper-excitation or seizures. Considering that astrocytes play important roles in mediating local uptake and spatial buffering of K+ in the extracellular space of the cortical circuit, we constructed a novel model of an astrocyte-neuron network module consisting of a single compartment neuron and 4 surrounding connected astrocytes and including extracellular potassium dynamics. Next, we developed a new model function for the astrocyte gap junctions, connecting two astrocyte-neuron network modules. The function form and parameters of the gap junction were based on nonlinear regression fitting of a set of experimental data published in previous studies. Moreover, we have created numerical simulations using the above single astrocyte-neuron network module and the coupled astrocyte-neuron network modules. Our model validates previous experimental observations that both Kir4.1 channels and gap junctions play important roles in regulating the concentration of extracellular potassium. In addition, we also observe that changes in Kir4.1 channel conductance and gap junction strength induce spontaneous epileptic activity in the absence of external stimuli. PMID- 29590096 TI - Large scale variation in the rate of germ-line de novo mutation, base composition, divergence and diversity in humans. AB - It has long been suspected that the rate of mutation varies across the human genome at a large scale based on the divergence between humans and other species. However, it is now possible to directly investigate this question using the large number of de novo mutations (DNMs) that have been discovered in humans through the sequencing of trios. We investigate a number of questions pertaining to the distribution of mutations using more than 130,000 DNMs from three large datasets. We demonstrate that the amount and pattern of variation differs between datasets at the 1MB and 100KB scales probably as a consequence of differences in sequencing technology and processing. In particular, datasets show different patterns of correlation to genomic variables such as replication time. Never-the less there are many commonalities between datasets, which likely represent true patterns. We show that there is variation in the mutation rate at the 100KB, 1MB and 10MB scale that cannot be explained by variation at smaller scales, however the level of this variation is modest at large scales-at the 1MB scale we infer that ~90% of regions have a mutation rate within 50% of the mean. Different types of mutation show similar levels of variation and appear to vary in concert which suggests the pattern of mutation is relatively constant across the genome. We demonstrate that variation in the mutation rate does not generate large-scale variation in GC-content, and hence that mutation bias does not maintain the isochore structure of the human genome. We find that genomic features explain less than 40% of the explainable variance in the rate of DNM. As expected the rate of divergence between species is correlated to the rate of DNM. However, the correlations are weaker than expected if all the variation in divergence was due to variation in the mutation rate. We provide evidence that this is due the effect of biased gene conversion on the probability that a mutation will become fixed. In contrast to divergence, we find that most of the variation in diversity can be explained by variation in the mutation rate. Finally, we show that the correlation between divergence and DNM density declines as increasingly divergent species are considered. PMID- 29590097 TI - Modeling the dynamics of oligodendrocyte precursor cells and the genesis of gliomas. AB - Oligodendrocyte precursor cells (OPCs) have remarkable properties: they represent the most abundant cycling cell population in the adult normal brain and they manage to achieve a uniform and constant density throughout the adult brain. This equilibrium is obtained by the interplay of four processes: division, differentiation or death, migration and active self-repulsion. They are also strongly suspected to be at the origin of gliomas, when their equilibrium is disrupted. In this article, we present a model of the dynamics of OPCs, first in a normal tissue. This model is based on a cellular automaton and its rules are mimicking the ones that regulate the dynamics of real OPCs. The model is able to reproduce the homeostasis of the cell population, with the maintenance of a constant and uniform cell density and the healing of a lesion. We show that there exists a fair quantitative agreement between the simulated and experimental parameters, such as the cell velocity, the time taken to close a lesion, and the duration of the cell cycle. We present three possible scenarios of disruption of the equilibrium: the appearance of an over-proliferating cell, of a deadless/non differentiating cell, or of a cell that lost any contact-inhibition. We show that the appearance of an over-proliferating cell is sufficient to trigger the growth of a tumor that has low-grade glioma features: an invasive behaviour, a linear radial growth of the tumor with a corresponding growth velocity of less than 2 mm per year, as well a cell density at the center which exceeds the one in normal tissue by a factor of less than two. The loss of contact inhibition leads to a more high-grade-like glioma. The results of our model contribute to the body of evidence that identify OPCs as possible cells of origin of gliomas. PMID- 29590098 TI - A chitinase with two catalytic domains is required for organization of the cuticular extracellular matrix of a beetle. AB - Insect cuticle or exoskeleton is an extracellular matrix formed primarily from two different structural biopolymers, chitin and protein. During each molt cycle, a new cuticle is deposited simultaneously with degradation of the inner part of the chitinous procuticle of the overlying old exoskeleton by molting fluid enzymes including epidermal chitinases. In this study we report a novel role for an epidermal endochitinase containing two catalytic domains, TcCHT7, from the red flour beetle, Tribolium castaneum, in organizing chitin in the newly forming cuticle rather than in degrading chitin present in the prior one. Recombinant TcCHT7 expressed in insect cells is membrane-bound and capable of hydrolyzing an extracellular chitin substrate, whereas in vivo, this enzyme is also released from the plasma membrane and co-localizes with chitin in the entire procuticle. RNAi of TcCHT7 reveals that this enzyme is nonessential for any type of molt or degradation of the chitinous matrix in the old cuticle. In contrast, TcCHT7 is required for maintaining the integrity of the cuticle as a compact structure of alternating electron-dense and electron-lucent laminae. There is a reduction in thickness of elytral and leg cuticles after RNAi for TcCHT7. TcCHT7 is also required for formation of properly oriented long chitin fibers inside pore canals that are vertically oriented columnar structures, which contribute to the mechanical strength of a light-weight, yet rigid, adult cuticle. The conservation of CHT7-like proteins harboring such a unique domain configuration among many insect and other arthropod species indicates a critical role for the group III class of chitinases in the higher ordered organization of chitin fibers for development of the structural integrity of many invertebrate exoskeletons. PMID- 29590099 TI - Polycystic ovary syndrome, androgen excess, and the risk of nonalcoholic fatty liver disease in women: A longitudinal study based on a United Kingdom primary care database. AB - BACKGROUND: Androgen excess is a defining feature of polycystic ovary syndrome (PCOS), which affects 10% of women and represents a lifelong metabolic disorder, with increased risk of type 2 diabetes, hypertension, and cardiovascular events. Previous studies have suggested an increased risk of nonalcoholic fatty liver disease (NAFLD) in individuals with PCOS and implicated androgen excess as a potential driver. METHODS AND FINDINGS: We carried out a retrospective longitudinal cohort study utilizing a large primary care database in the United Kingdom, evaluating NAFLD rates in 63,120 women with PCOS and 121,064 age-, body mass index (BMI)-, and location-matched control women registered from January 2000 to May 2016. In 2 independent cohorts, we also determined the rate of NAFLD in women with a measurement of serum testosterone (n = 71,061) and sex hormone binding globulin (SHBG; n = 49,625). We used multivariate Cox models to estimate the hazard ratio (HR) for NAFLD and found that women with PCOS had an increased rate of NAFLD (HR = 2.23, 95% CI 1.86-2.66, p < 0.001), also after adjusting for BMI or dysglycemia. Serum testosterone >3.0 nmol/L was associated with an increase in NAFLD (HR = 2.30, 95% CI 1.16-4.53, p = 0.017 for 3-3.49 nmol/L and HR = 2.40, 95% CI 1.24-4.66, p = 0.009 for >3.5 nmol/L). Mirroring this finding, SHBG <30 nmol/L was associated with increased NAFLD hazard (HR = 4.75, 95% CI 2.44-9.25, p < 0.001 for 20-29.99 nmol/L and HR = 4.98, 95% CI 2.45-10.11, p < 0.001 for <20 nmol/L). Limitations of this study include its retrospective nature, absence of detailed information on criteria used to diagnosis PCOS and NAFLD, and absence of data on laboratory assays used to measure serum androgens. CONCLUSIONS: We found that women with PCOS have an increased rate of NAFLD. In addition to increased BMI and dysglycemia, androgen excess contributes to the development of NAFLD in women with PCOS. In women with PCOS-related androgen excess, systematic NAFLD screening should be considered. PMID- 29590101 TI - Bamgineer: Introduction of simulated allele-specific copy number variants into exome and targeted sequence data sets. AB - Somatic copy number variations (CNVs) play a crucial role in development of many human cancers. The broad availability of next-generation sequencing data has enabled the development of algorithms to computationally infer CNV profiles from a variety of data types including exome and targeted sequence data; currently the most prevalent types of cancer genomics data. However, systemic evaluation and comparison of these tools remains challenging due to a lack of ground truth reference sets. To address this need, we have developed Bamgineer, a tool written in Python to introduce user-defined haplotype-phased allele-specific copy number events into an existing Binary Alignment Mapping (BAM) file, with a focus on targeted and exome sequencing experiments. As input, this tool requires a read alignment file (BAM format), lists of non-overlapping genome coordinates for introduction of gains and losses (bed file), and an optional file defining known haplotypes (vcf format). To improve runtime performance, Bamgineer introduces the desired CNVs in parallel using queuing and parallel processing on a local machine or on a high-performance computing cluster. As proof-of-principle, we applied Bamgineer to a single high-coverage (mean: 220X) exome sequence file from a blood sample to simulate copy number profiles of 3 exemplar tumors from each of 10 tumor types at 5 tumor cellularity levels (20-100%, 150 BAM files in total). To demonstrate feasibility beyond exome data, we introduced read alignments to a targeted 5-gene cell-free DNA sequencing library to simulate EGFR amplifications at frequencies consistent with circulating tumor DNA (10, 1, 0.1 and 0.01%) while retaining the multimodal insert size distribution of the original data. We expect Bamgineer to be of use for development and systematic benchmarking of CNV calling algorithms by users using locally-generated data for a variety of applications.

PMID- 29590100 TI - Glial loss of the metallo beta-lactamase domain containing protein, SWIP-10, induces age- and glutamate-signaling dependent, dopamine neuron degeneration. AB - Across phylogeny, glutamate (Glu) signaling plays a critical role in regulating neural excitability, thus supporting many complex behaviors. Perturbed synaptic and extrasynaptic Glu homeostasis in the human brain has been implicated in multiple neuropsychiatric and neurodegenerative disorders including Parkinson's disease, where theories suggest that excitotoxic insults may accelerate a naturally occurring process of dopamine (DA) neuron degeneration. In C. elegans, mutation of the glial expressed gene, swip-10, results in Glu-dependent DA neuron hyperexcitation that leads to elevated DA release, triggering DA signaling dependent motor paralysis. Here, we demonstrate that swip-10 mutations induce premature and progressive DA neuron degeneration, with light and electron microscopy studies demonstrating the presence of dystrophic dendritic processes, as well as shrunken and/or missing cell soma. As with paralysis, DA neuron degeneration in swip-10 mutants is rescued by glial-specific, but not DA neuron specific expression of wildtype swip-10, consistent with a cell non-autonomous mechanism. Genetic studies implicate the vesicular Glu transporter VGLU-3 and the cystine/Glu exchanger homolog AAT-1 as potential sources of Glu signaling supporting DA neuron degeneration. Degeneration can be significantly suppressed by mutations in the Ca2+ permeable Glu receptors, nmr-2 and glr-1, in genes that support intracellular Ca2+ signaling and Ca2+-dependent proteolysis, as well as genes involved in apoptotic cell death. Our studies suggest that Glu stimulation of nematode DA neurons in early larval stages, without the protective actions of SWIP-10, contributes to insults that ultimately drive DA neuron degeneration. The swip-10 model may provide an efficient platform for the identification of molecular mechanisms that enhance risk for Parkinson's disease and/or the identification of agents that can limit neurodegenerative disease progression. PMID- 29590102 TI - Common alpha-globin variants modify hematologic and other clinical phenotypes in sickle cell trait and disease. AB - Co-inheritance of alpha-thalassemia has a significant protective effect on the severity of complications of sickle cell disease (SCD), including stroke. However, little information exists on the association and interactions for the common African ancestral alpha-thalassemia mutation (-alpha3.7 deletion) and beta globin traits (HbS trait [SCT] and HbC trait) on important clinical phenotypes such as red blood cell parameters, anemia, and chronic kidney disease (CKD). In a community-based cohort of 2,916 African Americans from the Jackson Heart Study, we confirmed the expected associations between SCT, HbC trait, and the -alpha3.7 deletion with lower mean corpuscular volume/mean corpuscular hemoglobin and higher red blood cell count and red cell distribution width. In addition to the recently recognized association of SCT with lower estimated glomerular filtration rate and glycated hemoglobin (HbA1c), we observed a novel association of the alpha3.7 deletion with higher HbA1c levels. Co-inheritance of each additional copy of the -alpha3.7 deletion significantly lowered the risk of anemia and chronic kidney disease among individuals with SCT (P-interaction = 0.031 and 0.019, respectively). Furthermore, co-inheritance of a novel alpha-globin regulatory variant was associated with normalization of red cell parameters in individuals with the -alpha3.7 deletion and significantly negated the protective effect of alpha-thalassemia on stroke in 1,139 patients with sickle cell anemia from the Cooperative Study of Sickle Cell Disease (CSSCD) (P-interaction = 0.0049). Functional assays determined that rs11865131, located in the major alpha globin enhancer MCS-R2, was the most likely causal variant. These findings suggest that common alpha- and beta-globin variants interact to influence hematologic and clinical phenotypes in African Americans, with potential implications for risk-stratification and counseling of individuals with SCD and SCT. PMID- 29590103 TI - Preferential retention of genes from one parental genome after polyploidy illustrates the nature and scope of the genomic conflicts induced by hybridization. AB - Polyploidy is increasingly seen as a driver of both evolutionary innovation and ecological success. One source of polyploid organisms' successes may be their origins in the merging and mixing of genomes from two different species (e.g., allopolyploidy). Using POInT (the Polyploid Orthology Inference Tool), we model the resolution of three allopolyploidy events, one from the bakers' yeast (Saccharomyces cerevisiae), one from the thale cress (Arabidopsis thaliana) and one from grasses including Sorghum bicolor. Analyzing a total of 21 genomes, we assign to every gene a probability for having come from each parental subgenome (i.e., derived from the diploid progenitor species), yielding orthologous segments across all genomes. Our model detects statistically robust evidence for the existence of biased fractionation in all three lineages, whereby genes from one of the two subgenomes were more likely to be lost than those from the other subgenome. We further find that a driver of this pattern of biased losses is the co-retention of genes from the same parental genome that share functional interactions. The pattern of biased fractionation after the Arabidopsis and grass allopolyploid events was surprisingly constant in time, with the same parental genome favored throughout the lineages' history. In strong contrast, the yeast allopolyploid event shows evidence of biased fractionation only immediately after the event, with balanced gene losses more recently. The rapid loss of functionally associated genes from a single subgenome is difficult to reconcile with the action of genetic drift and suggests that selection may favor the removal of specific duplicates. Coupled to the evidence for continuing, functionally-associated biased fractionation after the A. thaliana At-alpha event, we suggest that, after allopolyploidy, there are functional conflicts between interacting genes encoded in different subgenomes that are ultimately resolved through preferential duplicate loss. PMID- 29590104 TI - Autophagy is essential for maintaining the growth of a human (mini-)organ: Evidence from scalp hair follicle organ culture. AB - Autophagy plays a crucial role in health and disease, regulating central cellular processes such as adaptive stress responses, differentiation, tissue development, and homeostasis. However, the role of autophagy in human physiology is poorly understood, highlighting a need for a model human organ system to assess the efficacy and safety of strategies to therapeutically modulate autophagy. As a complete, cyclically remodelled (mini-)organ, the organ culture of human scalp hair follicles (HFs), which, after massive growth (anagen), spontaneously enter into an apoptosis-driven organ involution (catagen) process, may provide such a model. Here, we reveal that in anagen, hair matrix keratinocytes (MKs) of organ cultured HFs exhibit an active autophagic flux, as documented by evaluation of endogenous lipidated Light Chain 3B (LC3B) and sequestosome 1 (SQSTM1/p62) proteins and the ultrastructural visualization of autophagosomes at all stages of the autophagy process. This autophagic flux is altered during catagen, and genetic inhibition of autophagy promotes catagen development. Conversely, an anti hair loss product markedly enhances intrafollicular autophagy, leading to anagen prolongation. Collectively, our data reveal a novel role of autophagy in human hair growth. Moreover, we show that organ-cultured scalp HFs are an excellent preclinical research model for exploring the role of autophagy in human tissue physiology and for evaluating the efficacy and tissue toxicity of candidate autophagy-modulatory agents in a living human (mini-)organ. PMID- 29590105 TI - Effects of multiple sources of genetic drift on pathogen variation within hosts. AB - Changes in pathogen genetic variation within hosts alter the severity and spread of infectious diseases, with important implications for clinical disease and public health. Genetic drift may play a strong role in shaping pathogen variation, but analyses of drift in pathogens have oversimplified pathogen population dynamics, either by considering dynamics only at a single scale-such as within hosts or between hosts-or by making drastic simplifying assumptions, for example, that host immune systems can be ignored or that transmission bottlenecks are complete. Moreover, previous studies have used genetic data to infer the strength of genetic drift, whereas we test whether the genetic drift imposed by pathogen population processes can be used to explain genetic data. We first constructed and parameterized a mathematical model of gypsy moth baculovirus dynamics that allows genetic drift to act within and between hosts. We then quantified the genome-wide diversity of baculovirus populations within each of 143 field-collected gypsy moth larvae using Illumina sequencing. Finally, we determined whether the genetic drift imposed by host-pathogen population dynamics in our model explains the levels of pathogen diversity in our data. We found that when the model allows drift to act at multiple scales-including within hosts, between hosts, and between years-it can accurately reproduce the data, but when the effects of drift are simplified by neglecting transmission bottlenecks and stochastic variation in virus replication within hosts, the model fails. A de novo mutation model and a purifying selection model similarly fail to explain the data. Our results show that genetic drift can play a strong role in determining pathogen variation and that mathematical models that account for pathogen population growth at multiple scales of biological organization can be used to explain this variation. PMID- 29590106 TI - Tuning Hsf1 levels drives distinct fungal morphogenetic programs with depletion impairing Hsp90 function and overexpression expanding the target space. AB - The capacity to respond to temperature fluctuations is critical for microorganisms to survive within mammalian hosts, and temperature modulates virulence traits of diverse pathogens. One key temperature-dependent virulence trait of the fungal pathogen Candida albicans is its ability to transition from yeast to filamentous growth, which is induced by environmental cues at host physiological temperature. A key regulator of temperature-dependent morphogenesis is the molecular chaperone Hsp90, which has complex functional relationships with the transcription factor Hsf1. Although Hsf1 controls global transcriptional remodeling in response to heat shock, its impact on morphogenesis remains unknown. Here, we establish an intriguing paradigm whereby overexpression or depletion of C. albicans HSF1 induces morphogenesis in the absence of external cues. HSF1 depletion compromises Hsp90 function, thereby driving filamentation. HSF1 overexpression does not impact Hsp90 function, but rather induces a dose dependent expansion of Hsf1 direct targets that drives overexpression of positive regulators of filamentation, including Brg1 and Ume6, thereby bypassing the requirement for elevated temperature during morphogenesis. This work provides new insight into Hsf1-mediated environmentally contingent transcriptional control, implicates Hsf1 in regulation of a key virulence trait, and highlights fascinating biology whereby either overexpression or depletion of a single cellular regulator induces a profound developmental transition. PMID- 29590107 TI - Novel function of HATs and HDACs in homologous recombination through acetylation of human RAD52 at double-strand break sites. AB - The p300 and CBP histone acetyltransferases are recruited to DNA double-strand break (DSB) sites where they induce histone acetylation, thereby influencing the chromatin structure and DNA repair process. Whether p300/CBP at DSB sites also acetylate non-histone proteins, and how their acetylation affects DSB repair, remain unknown. Here we show that p300/CBP acetylate RAD52, a human homologous recombination (HR) DNA repair protein, at DSB sites. Using in vitro acetylated RAD52, we identified 13 potential acetylation sites in RAD52 by a mass spectrometry analysis. An immunofluorescence microscopy analysis revealed that RAD52 acetylation at DSBs sites is counteracted by SIRT2- and SIRT3-mediated deacetylation, and that non-acetylated RAD52 initially accumulates at DSB sites, but dissociates prematurely from them. In the absence of RAD52 acetylation, RAD51, which plays a central role in HR, also dissociates prematurely from DSB sites, and hence HR is impaired. Furthermore, inhibition of ataxia telangiectasia mutated (ATM) protein by siRNA or inhibitor treatment demonstrated that the acetylation of RAD52 at DSB sites is dependent on the ATM protein kinase activity, through the formation of RAD52, p300/CBP, SIRT2, and SIRT3 foci at DSB sites. Our findings clarify the importance of RAD52 acetylation in HR and its underlying mechanism. PMID- 29590108 TI - Cross-species multiple environmental stress responses: An integrated approach to identify candidate genes for multiple stress tolerance in sorghum (Sorghum bicolor (L.) Moench) and related model species. AB - BACKGROUND: Crop response to the changing climate and unpredictable effects of global warming with adverse conditions such as drought stress has brought concerns about food security to the fore; crop yield loss is a major cause of concern in this regard. Identification of genes with multiple responses across environmental stresses is the genetic foundation that leads to crop adaptation to environmental perturbations. METHODS: In this paper, we introduce an integrated approach to assess candidate genes for multiple stress responses across-species. The approach combines ontology based semantic data integration with expression profiling, comparative genomics, phylogenomics, functional gene enrichment and gene enrichment network analysis to identify genes associated with plant stress phenotypes. Five different ontologies, viz., Gene Ontology (GO), Trait Ontology (TO), Plant Ontology (PO), Growth Ontology (GRO) and Environment Ontology (EO) were used to semantically integrate drought related information. RESULTS: Target genes linked to Quantitative Trait Loci (QTLs) controlling yield and stress tolerance in sorghum (Sorghum bicolor (L.) Moench) and closely related species were identified. Based on the enriched GO terms of the biological processes, 1116 sorghum genes with potential responses to 5 different stresses, such as drought (18%), salt (32%), cold (20%), heat (8%) and oxidative stress (25%) were identified to be over-expressed. Out of 169 sorghum drought responsive QTLs associated genes that were identified based on expression datasets, 56% were shown to have multiple stress responses. On the other hand, out of 168 additional genes that have been evaluated for orthologous pairs, 90% were conserved across species for drought tolerance. Over 50% of identified maize and rice genes were responsive to drought and salt stresses and were co-located within multifunctional QTLs. Among the total identified multi-stress responsive genes, 272 targets were shown to be co-localized within QTLs associated with different traits that are responsive to multiple stresses. Ontology mapping was used to validate the identified genes, while reconstruction of the phylogenetic tree was instrumental to infer the evolutionary relationship of the sorghum orthologs. The results also show specific genes responsible for various interrelated components of drought response mechanism such as drought tolerance, drought avoidance and drought escape. CONCLUSIONS: We submit that this approach is novel and to our knowledge, has not been used previously in any other research; it enables us to perform cross-species queries for genes that are likely to be associated with multiple stress tolerance, as a means to identify novel targets for engineering stress resistance in sorghum and possibly, in other crop species. PMID- 29590109 TI - Serum VEGF-A concentrations in patients with central nervous system (CNS) tumors. AB - Angiogenesis plays an essential role in tumors development. In case of central nervous system tumors, the most important role in this process plays VEGF-A. The purpose of this study was to determine the plasma concentration of this agent in patients treated surgically because of intracranial tumors. The study involved 48 adult patients, both sexes, treated surgically because of a brain tumor. The control group consisted of 50 adult volunteers of both sexes, without cancer diagnosis. Based on the studies, it was found that serum VEGF-A levels before surgery are higher in patients with central nervous system tumors (10.39-150.57 pg/ml, median 41.70 pg/ml) than in non-cancer patients (0.00-130.77 pg/ml, median 22.56 pg/ml). The association between serum VEGF-A level and malignancy and histological type of intracranial tumor has not beed confirmed. The highest average preoperative serum VEGF-A level was found in patients with low grade gliomas, slightly lower (close to each other) in those with high grade gliomas and meningiomas, while the lowest level was characteristic for metastatic tumors. High variation in results was observed in patients with low grade gliomas (52.56 pg/ml)-higher than those reported in patients with high grade gliomas (32.38 pg/ml). In the rest types of tumors the differentiation was similar and oscillated within 23.08-27.50 pg/ml. PMID- 29590111 TI - An outer approximation method for the road network design problem. AB - Best investment in the road infrastructure or the network design is perceived as a fundamental and benchmark problem in transportation. Given a set of candidate road projects with associated costs, finding the best subset with respect to a limited budget is known as a bilevel Discrete Network Design Problem (DNDP) of NP hard computationally complexity. We engage with the complexity with a hybrid exact-heuristic methodology based on a two-stage relaxation as follows: (i) the bilevel feature is relaxed to a single-level problem by taking the network performance function of the upper level into the user equilibrium traffic assignment problem (UE-TAP) in the lower level as a constraint. It results in a mixed-integer nonlinear programming (MINLP) problem which is then solved using the Outer Approximation (OA) algorithm (ii) we further relax the multi-commodity UE-TAP to a single-commodity MILP problem, that is, the multiple OD pairs are aggregated to a single OD pair. This methodology has two main advantages: (i) the method is proven to be highly efficient to solve the DNDP for a large-sized network of Winnipeg, Canada. The results suggest that within a limited number of iterations (as termination criterion), global optimum solutions are quickly reached in most of the cases; otherwise, good solutions (close to global optimum solutions) are found in early iterations. Comparative analysis of the networks of Gao and Sioux-Falls shows that for such a non-exact method the global optimum solutions are found in fewer iterations than those found in some analytically exact algorithms in the literature. (ii) Integration of the objective function among the constraints provides a commensurate capability to tackle the multi objective (or multi-criteria) DNDP as well. PMID- 29590110 TI - Listening to a conversation with aggressive content expands the interpersonal space. AB - The distance individuals maintain between themselves and others can be defined as 'interpersonal space'. This distance can be modulated both by situational factors and individual characteristics. Here we investigated the influence that the interpretation of other people interaction, in which one is not directly involved, may have on a person's interpersonal space. In the current study we measured, for the first time, whether the size of interpersonal space changes after listening to other people conversations with neutral or aggressive content. The results showed that the interpersonal space expands after listening to a conversation with aggressive content relative to a conversation with a neutral content. This finding suggests that participants tend to distance themselves from an aggressive confrontation even if they are not involved in it. These results are in line with the view of the interpersonal space as a safety zone surrounding one's body. PMID- 29590112 TI - Active BRAF-V600E is the key player in generation of a sessile serrated polyp specific DNA methylation profile. AB - BACKGROUND: Sessile serrated polyps (SSPs) have emerged as important precursors for a large number of sporadic colorectal cancers. They are difficult to detect during colonoscopy due to their flat shape and the excessive amounts of secreted mucin that cover the polyps. The underlying genetic and epigenetic basis for the emergence of SSPs is largely unknown with existing genetic studies confined to a limited number of oncogenes and tumor suppressors. A full characterization of the genetic and epigenetic landscape of SSPs would provide insight into their origin and potentially offer new biomarkers useful for detection of SSPs in stool samples. METHODS: We used a combination of genome-wide mutation detection, exome sequencing and DNA methylation profiling (via methyl-array and whole-genome bisulfite sequencing) to analyze multiple samples of sessile serrated polyps and compared these to familial adenomatous polyps. RESULTS: Our analysis revealed BRAF-V600E as the sole recurring somatic mutation in SSPs with no additional major genetic mutations detected. The occurrence of BRAF-V600E was coincident with a unique DNA methylation pattern revealing a set of DNA methylation markers showing significant (~3 to 30 fold) increase in their methylation levels, exclusively in SSP samples. These methylation patterns effectively distinguished sessile serrated polys from adenomatous polyps and did so more effectively than parallel gene expression profiles. CONCLUSIONS: This study provides an important example of a single oncogenic mutation leading to reproducible global DNA methylation changes. These methylated markers are specific to SSPs and could be of important clinical relevance for the early diagnosis of SSPs using non invasive approaches such as fecal DNA testing. PMID- 29590113 TI - The water relations and xylem attributes of albino redwood shoots (Sequioa sempervirens (D. Don.) Endl.). AB - Plants that lack chlorophyll are rare and typically restricted to holoparasites that obtain their carbon, water and mineral resources from a host plant. Although not parasites in the traditional sense, albino foliage, such as the sprouts that sometimes develop from redwood tree trunks, are comparable in function. They occur sporadically, and can reach the size of shrubs and in rare cases, trees. Albino redwoods are interesting because in addition to their reduced carbon resources, the absence of chloroplasts may impede proper stomatal function, and both aspects may have upstream consequences on water transport and xylem quality. We examined the water relations, water transport and xylem anatomical attributes of albino redwoods and show that similar to achlorophyllous and parasitic plants, albino redwoods have notably higher stomatal conductance than green sprouts. Given that stem xylem tracheid size as well as water transport efficiency are nearly equivalent in both albino and green individuals, we attribute the increased leaf water loss in albino sprouts to lower leaf to xylem area ratios, which favour improved hydration relative to green sprouts. The stems of albino redwoods were more vulnerable to drought-induced embolism than green stems, and this was consistent with the albino's weaker tracheids, as characterized by wall thickness to lumen diameter measures. Our results are both complementary and consistent with previous research on achlorophyllous plants, and suggest that the loss of stomatal control and photosynthetic capacity results in substantial vascular and anatomical adjustments. PMID- 29590114 TI - Mutations in Diphosphoinositol-Pentakisphosphate Kinase PPIP5K2 are associated with hearing loss in human and mouse. AB - Autosomal recessive nonsyndromic hearing loss is a genetically heterogeneous disorder. Here, we report a severe-to-profound sensorineural hearing loss locus, DFNB100 on chromosome 5q13.2-q23.2. Exome enrichment followed by massive parallel sequencing revealed a c.2510G>A transition variant in PPIP5K2 that segregated with DFNB100-associated hearing loss in two large apparently unrelated Pakistani families. PPIP5Ks enzymes interconvert 5-IP7 and IP8, two key members of the inositol pyrophosphate (PP-IP) cell-signaling family. Their actions at the interface of cell signaling and bioenergetic homeostasis can impact many biological processes. The c.2510G>A transition variant is predicted to substitute a highly invariant arginine residue with histidine (p.Arg837His) in the phosphatase domain of PPIP5K2. Biochemical studies revealed that the p.Arg837His variant reduces the phosphatase activity of PPIP5K2 and elevates its kinase activity. We found that in mouse inner ear, PPIP5K2 is expressed in the cochlear and vestibular sensory hair cells, supporting cells and spiral ganglion neurons. Mice homozygous for a targeted deletion of the Ppip5k2 phosphatase domain exhibit degeneration of cochlear outer hair cells and elevated hearing thresholds. Our demonstration that PPIP5K2 has a role in hearing in humans indicates that PP-IP signaling is important to hair cell maintenance and function within inner ear. PMID- 29590115 TI - Impaired neuronal maturation of hippocampal neural progenitor cells in mice lacking CRAF. AB - RAF kinases are major constituents of the mitogen activated signaling pathway, regulating cell proliferation, differentiation and cell survival of many cell types, including neurons. In mammals, the family of RAF proteins consists of three members, ARAF, BRAF, and CRAF. Ablation of CRAF kinase in inbred mouse strains causes major developmental defects during fetal growth and embryonic or perinatal lethality. Heterozygous germline mutations in CRAF result in Noonan syndrome, which is characterized by neurocognitive impairment that may involve hippocampal physiology. The role of CRAF signaling during hippocampal development and generation of new postnatal hippocampal granule neurons has not been examined and may provide novel insight into the cause of hippocampal dysfunction in Noonan syndrome. In this study, by crossing CRAF-deficiency to CD-1 outbred mice, a CRAF mouse model was established which enabled us to investigate the interplay of neural progenitor proliferation and postmitotic differentiation during adult neurogenesis in the hippocampus. Albeit the general morphology of the hippocampus was unchanged, CRAF-deficient mice displayed smaller granule cell layer (GCL) volume at postnatal day 30 (P30). In CRAF-deficient mice a substantial number of abnormal, chromophilic, fast dividing cells were found in the subgranular zone (SGZ) and hilus of the dentate gyrus (DG), indicating that CRAF signaling contributes to hippocampal neural progenitor proliferation. CRAF-deficient neural progenitor cells showed an increased cell death rate and reduced neuronal maturation. These results indicate that CRAF function affects postmitotic neural cell differentiation and points to a critical role of CRAF-dependent growth factor signaling pathway in the postmitotic development of adult-born neurons. PMID- 29590117 TI - A terrestrial vertebrate palaeontological review of Aldabra Atoll, Aldabra Group, Seychelles. AB - The Pleistocene vertebrate assemblage of Aldabra Atoll has been comparatively well studied. Three Upper Pleistocene fossil localities have been described yielding birds, reptiles and terrestrial molluscs. Those of Bassin Cabri and Bassin Lebine on Ile Picard are undated but must be in excess of 136,000 YBP, whereas Point Hodoul on Malabar Island is circa 100,000 YBP. Aldabra was seemingly completely submerged between deposition of the Ile Picard and Point Hodoul deposits, resulting in local faunal extinctions. Here we present the results of an ongoing study of fossil material collected on Ile Picard in 1987, which reveals a more diverse assemblage than previously realised. Notable discoveries are an Ardeola heron, three Procellariformes, tropic-bird Phaethon, gull Larus, rail Dryolimnas, harrier Circus and owl Tyto, plus evidence of recolonisation of the atoll by some seabirds, rail, harrier, owl, giant tortoises and lizards after the Ile Picard/Point Hodoul submergence event. PMID- 29590116 TI - Prospective evaluation of a rapid diagnostic test for Trypanosoma brucei gambiense infection developed using recombinant antigens. AB - BACKGROUND: Diagnosis and treatment are central elements of strategies to control Trypanosoma brucei gambiense human African trypanosomiasis (HAT). Serological screening is a key entry point in diagnostic algorithms. The Card Agglutination Test for Trypanosomiasis (CATT) has been the most widely used screening test for decades, despite a number of practical limitations that were partially addressed by the introduction of rapid diagnostic tests (RDTs). However, current RDTs are manufactured using native antigens, which are challenging to produce. METHODOLOGY/PRINCIPAL FINDINGS: The objective of this study was to evaluate the accuracy of a new RDT developed using recombinant antigens (SD BIOLINE HAT 2.0), in comparison with an RDT produced using native antigens (SD BIOLINE HAT) and CATT. A total of 57,632 individuals were screened in the Democratic Republic of the Congo, either passively at 10 health centres, or actively by 5 mobile teams, and 260 HAT cases were confirmed by parasitology. The highest sensitivity was achieved with the SD BIOLINE HAT 2.0 (71.2%), followed by CATT (62.5%) and the SD BIOLINE HAT (59.0%). The most specific test was CATT (99.2%), while the specificity of the SD BIOLINE HAT and SD BIOLINE HAT 2.0 were 98.9% and 98.1%, respectively. Sensitivity of the tests was lower than previously reported, as they identified cases from partially overlapping sub-populations. All three tests were significantly more sensitive in passive than in active screening. Combining two or three tests resulted in a markedly increased sensitivity: When the SD BIOLINE HAT was combined with the SD BIOLINE HAT 2.0, sensitivity reached 98.4% in passive and 83.0% in active screening. CONCLUSIONS/SIGNIFICANCE: The recombinant antigen-based RDT was more sensitive than, and as specific as, the SD BIOLINE HAT. It was as sensitive as, but slightly less specific than CATT. While the practicality and cost-effectiveness of algorithms including several screening tests would need to be investigated, using two or more tests appears to enhance sensitivity of diagnostic algorithms, although some decrease in specificity is observed as well. PMID- 29590118 TI - Association between periconceptional weight loss and maternal and neonatal outcomes in obese infertile women. AB - BACKGROUND: Obesity in women of reproductive age has deleterious effects on reproductive and offspring health. In this study, we aimed to evaluate the association between the magnitude of periconceptional body-mass index (BMI) change and maternal and neonatal outcomes in obese infertile women who participated in the LIFEstyle study. The LIFEstyle study was a randomized controlled trial, evaluating if a six-month lifestyle intervention program prior to infertility treatment in obese infertile women improved birth rates, compared to prompt infertility treatment. METHODS AND FINDINGS: This is an exploratory post hoc analysis of the LIFEstyle study. We recorded periconceptional BMI change in women with an ongoing pregnancy, pooling data of all women, regardless of randomization arm. Periconceptional BMI change was calculated using weight at randomization and the periconceptional weight (measured in kilograms 12 weeks before or after conception and expressed as BMI change in units BMI (kg/m2)). Subsequently, women were categorized into quartiles according to the magnitude of their periconceptional change in BMI. The odds of maternal and neonatal outcomes were calculated using logistic regression analysis, comparing women in each of the first three weight change quartiles separately, and combined, to women in the fourth quartile. The fourth quartile was chosen as reference group, since these women had the least weight loss. We adjusted for periconceptional BMI, nulliparity and smoking status. In addition, we performed a subgroup analysis for singleton pregnancies. In the LIFEstyle study, 321 obese infertile women achieved an ongoing pregnancy which was conceived within 24 months after randomization. Periconceptional BMI change was available in 244 of these women (76%). Median BMI at randomization was 35.9 kg/m2. Women in the first quartile (Q1) had a periconceptional BMI change of <-2.1 kg/m2, women in the second quartile (Q2) 2.1 to -0.9 kg/m2, women in the third quartile (Q3) -0.9 to 0.1 kg/m2 and women in the fourth quartile (Q4) gained >=0.1 kg/m2. There were no significant differences between women in the quartiles regarding rates of excessive gestational weight gain (in term pregnancies), gestational diabetes, preterm birth, induction of labor, spontaneous vaginal birth and Caesarean section. Compared to women in Q4, the adjusted odds ratios, aOR, and 95% confidence interval for a hypertensive complication were; 0.55 (0.22-1.42) for women in Q1, 0.30 (0.12-0.78) for women in Q2, 0.39 (0.16-0.96) for women in Q3 and 0.39 (0.19 0.82) for women in Q1 to Q3 combined. In the subgroup analysis, investigating singleton pregnancies only, the statistically significant decreased rate of a hypertensive complication remained in women in Q2 (aOR 0.27, 95% CI 0.10-0.72) and Q3 (aOR 0.39, 95%CI 0.16-0.98) and when comparing women in Q1 to Q3 together to women in Q4 (aOR 0.38, 95%CI 0.18-0.80). Furthermore, there was a significantly decreased aOR (95%CI) of preterm birth in women in Q2 (0.24, 0.06 0.98) and when combining women in Q1 to Q3 (0.37, 0.14-0.97) compared to women in Q4. CONCLUSIONS: These results suggest that a periconceptional decrease in BMI in obese infertile women could lead to a decrease of the rates of hypertensive pregnancy complications and preterm birth. The results are limited by the exploratory nature of the analyses and further evidence is necessary to provide more definitive conclusions. PMID- 29590119 TI - NF90/ILF3 is a transcription factor that promotes proliferation over differentiation by hierarchical regulation in K562 erythroleukemia cells. AB - NF90 and splice variant NF110 are DNA- and RNA-binding proteins encoded by the Interleukin enhancer-binding factor 3 (ILF3) gene that have been established to regulate RNA splicing, stabilization and export. The roles of NF90 and NF110 in regulating transcription as chromatin-interacting proteins have not been comprehensively characterized. Here, chromatin immunoprecipitation followed by deep sequencing (ChIP-seq) identified 9,081 genomic sites specifically occupied by NF90/NF110 in K562 cells. One third of NF90/NF110 peaks occurred at promoters of annotated genes. NF90/NF110 occupancy colocalized with chromatin marks associated with active promoters and strong enhancers. Comparison with 150 ENCODE ChIP-seq experiments revealed that NF90/NF110 clustered with transcription factors exhibiting preference for promoters over enhancers (POLR2A, MYC, YY1). Differential gene expression analysis following shRNA knockdown of NF90/NF110 in K562 cells revealed that NF90/NF110 activates transcription factors that drive growth and proliferation (EGR1, MYC), while attenuating differentiation along the erythroid lineage (KLF1). NF90/NF110 associates with chromatin to hierarchically regulate transcription factors that promote proliferation and suppress differentiation. PMID- 29590120 TI - The associations between water and sanitation and hookworm infection using cross sectional data from Togo's national deworming program. AB - BACKGROUND: Sustainable control of soil-transmitted helminths requires a combination of chemotherapy treatment and environmental interventions, including access to safe drinking water, sufficient water for hygiene, use of clean sanitation facilities, and handwashing (WASH). We quantified associations between home-, school-, and community-level WASH characteristics and hookworm infection both prevalence and eggs per gram of stool (intensity)-among Togolese school children in the context of community-based chemotherapy treatments administered in the country from 2010 through 2014. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed data from two surveys conducted by the Togo Ministry of Health: a school based survey of students aged 6-9 years across Togo conducted in 2009 and a follow-up survey in 2015, after four to five years of preventive chemotherapy. Data were available for 16,473 students attending 1,129 schools in 2009 and for 16,890 students from 1,126 schools in 2015. Between surveys, children in study schools received 0 to 8 rounds of deworming chemotherapy treatments. Few WASH conditions (only unimproved drinking water) were found to be significantly associated with the presence or absence of hookworms in an individual; however, quantitative eggs per gram of feces was associated with availability of unimproved drinking water, availability of improved drinking water either on or off school grounds, having a handwashing station with water available, and access to a sex-separate non-private or private latrine. The association between school WASH conditions and hookworm infection or burden often depended on the 2009 prevalence of infection, as more WASH characteristics were found to be significant predictors of infection among schools with high underlying endemicity of hookworm. CONCLUSIONS/SIGNIFICANCE: Our findings emphasize the complex and often inconsistent or unpredictable relationship between WASH and hookworm. Specifically, we found that while preventive chemotherapy appeared to dramatically reduce hookworm infection, WASH was associated with infection intensity. PMID- 29590121 TI - A test of the symbol interdependency hypothesis with both concrete and abstract stimuli. AB - In Experiment 1, the symbol interdependency hypothesis was tested with both concrete and abstract stimuli. Symbolic (i.e., semantic neighbourhood distance) and embodied (i.e., iconicity) factors were manipulated in two tasks-one that tapped symbolic relations (i.e., semantic relatedness judgment) and another that tapped embodied relations (i.e., iconicity judgment). Results supported the symbol interdependency hypothesis in that the symbolic factor was recruited for the semantic relatedness task and the embodied factor was recruited for the iconicity task. Across tasks, and especially in the iconicity task, abstract stimuli resulted in shorter RTs. This finding was in contrast to the concreteness effect where concrete words result in shorter RTs. Experiment 2 followed up on this finding by replicating the iconicity task from Experiment 1 in an ERP paradigm. Behavioural results continued to show a reverse concreteness effect with shorter RTs for abstract stimuli. However, ERP results paralleled the N400 and anterior N700 concreteness effects found in the literature, with more negative amplitudes for concrete stimuli. PMID- 29590122 TI - Association between six-minute walk distance and long-term outcomes in patients with pulmonary arterial hypertension: Data from the randomized SERAPHIN trial. AB - BACKGROUND: Patients with pulmonary arterial hypertension who achieve a six minute walk distance of 380-440 m may have improved prognosis. Using the randomized controlled trial of macitentan in pulmonary arterial hypertension (SERAPHIN), the association between six-minute walk distance and long-term outcomes was explored. METHODS: Patients with six-minute walk distance data at Month 6 were dichotomized as above or below the median six-minute walk distance (400 m) and assessed for future risk of pulmonary arterial hypertension-related death or hospitalization and all-cause death. Additionally, six-minute walk distance values at baseline, Month 6 and the change from baseline to Month 6 were categorized by quartiles. All associations were analyzed by the Kaplan-Meier method using a log-rank test and Cox regression models. RESULTS: Patients with a six-minute walk distance >400 m vs. <=400 m at Month 6 have a reduced risk of pulmonary arterial hypertension-related death or hospitalization (hazard ratio 0.48; 95% confidence interval 0.33-0.69). The risk was also lower for patients with higher quartiles of six-minute walk distance at baseline or Month 6 (baseline: hazard ratio [Q4 (>430 m) vs. Q1 (<=300 m)] 0.23; 95% confidence interval 0.15-0.36; Month 6: hazard ratio [Q4 (>455 m) vs. Q1 (<=348 m)] 0.33; 95% confidence interval 0.19-0.55). In contrast, six-minute walk distance changes at Month 6 were not associated with the risk of pulmonary arterial hypertension related death or hospitalization (p = 0.477). These findings were consistent when adjusted for known confounders. Similar results were observed for the risk of all cause death up to end of study. CONCLUSIONS: Patients with pulmonary arterial hypertension walking >400 m had better long-term prognosis. Although changes in six-minute walk distance were not associated with long-term outcomes, assessing absolute six-minute walk distance values remains important in the clinical management of patients with pulmonary arterial hypertension. PMID- 29590123 TI - Ontogeny of juvenile freshwater pearl mussels, Margaritifera margaritifera (Bivalvia: Margaritiferidae). AB - The gills of juvenile freshwater bivalves undergo a complex morphogenesis that may correlate with changes in feeding ecology, but ontogenic studies on juvenile mussels are rare. Scanning electron microscopy was used to examine the ultrastructure and ontogeny of 117 juvenile freshwater pearl mussels (Margaritifera margaritifera) ranging in age from 1-44 months and length from 0.49-8.90 mm. Three stages of gill development are described. In Stage 1 (5-9 inner demibranch filaments), only unreflected inner demibranch filaments were present. In Stage 2 (9-17 inner demibranch filaments), inner demibranch filaments began to reflect when shell length exceeded 1.13 mm, at 13-16 months old. Reflection began in medial filaments and then proceeded anterior and posterior. In Stage 3 (28-94 inner demibranch filaments), outer demibranch filaments began developing at shell length > 3.1 mm and about 34 months of age. The oral groove on the inner demibranch was first observed in 34 month old specimens > 2.66 mm but was never observed on the outer demibranch. Shell length (R2 = 0.99) was a better predictor of developmental stage compared to age (R2 = 0.84). The full suite of gill ciliation was present on filaments in all stages. Interfilamentary distance averaged 31.3 MUm and did not change with age (4-44 months) or with size (0.75-8.9 mm). Distance between laterofrontal cirri couplets averaged 1.54 MUm and did not change significantly with size or age. Labial palp primordia were present in even the youngest individuals but ciliature became more diverse in more developed individuals. Information presented here is valuable to captive rearing programmes as it provides insight in to when juveniles may be particularly vulnerable to stressors due to specific ontogenic changes. The data are compared with two other recent studies of Margaritifera development. PMID- 29590124 TI - The Basel Face Database: A validated set of photographs reflecting systematic differences in Big Two and Big Five personality dimensions. AB - Upon a first encounter, individuals spontaneously associate faces with certain personality dimensions. Such first impressions can strongly impact judgments and decisions and may prove highly consequential. Researchers investigating the impact of facial information often rely on (a) real photographs that have been selected to vary on the dimension of interest, (b) morphed photographs, or (c) computer-generated faces (avatars). All three approaches have distinct advantages. Here we present the Basel Face Database, which combines these advantages. In particular, the Basel Face Database consists of real photographs that are subtly, but systematically manipulated to show variations in the perception of the Big Two and the Big Five personality dimensions. To this end, the information specific to each psychological dimension is isolated and modeled in new photographs. Two studies serve as systematic validation of the Basel Face Database. The Basel Face Database opens a new pathway for researchers across psychological disciplines to investigate effects of perceived personality. PMID- 29590125 TI - Automatic social comparison: Cognitive load facilitates an increase in negative thought accessibility after thin ideal exposure among women. AB - Women are routinely exposed to images of extremely slim female bodies (the thin ideal) in advertisements, even if they do not necessarily pay much attention to these images. We hypothesized that paradoxically, it is precisely in such conditions of low attention that the impact of the social comparison with the thin ideal might be the most pronounced. To test this prediction, one hundred and seventy-three young female participants were exposed to images of the thin ideal or of women's fashion accessories. They were allocated to either a condition of high (memorizing 10 digits) or low cognitive load (memorizing 4 digits). The main dependent measure was implicit: mean recognition latency of negative words, relative to neutral words, as assessed by a lexical decision task. The results showed that thin-ideal exposure did not affect negative word accessibility under low cognitive load but that it increased it under high cognitive load. These findings are consistent with the hypothesis that social comparison with the thin ideal is an automatic process, and contribute to explain why some strategies to prevent negative effects of thin-ideal exposure are inefficient. PMID- 29590126 TI - Risk of venous thromboembolism during rehabilitation of patients with spinal cord injury. AB - BACKGROUND: Patients with spinal cord injury (SCI) are at risk of thrombosis and bleeding. Data on the risks during rehabilitation are inconsistent, and thromboprophylactic strategies are heterogeneous. We aimed to evaluate the thrombotic risk and bleeding events of SCI patients during rehabilitation. METHODS: We retrospectively collected hospital record data of 263 consecutive SCI patients admitted at a rehabilitation clinic. 78 patients with acute venous thromboembolism (VTE) at the primary center, without acute trauma or lower extremity paresis, less than one month rehabilitation, or reasons for long-term therapeutic anticoagulation, were excluded. All patients received pharmacologic thromboprophylaxis throughout rehabilitation. Primary endpoint was objectively diagnosed VTE; secondary endpoint was bleeding. RESULTS: Of 185 patients, 162 (88%) were men; mean age was 47.8 years. 94 patients were tetraplegic, 91 paraplegic. During a mean (+/-SD) time of 5.1+/-2.1 months, VTE was diagnosed in 8 patients. After excluding five patients with VTE detected within 2 days after admission, the probability of developing VTE after 6 months of rehabilitation was 2% (95% CI 0-4.4%). Only high D-Dimer upon admission was associated with risk of VTE (adjusted HR 2.3, 95% CI 1.4-4.1). Of 24 bleedings, 14 (64%) occurred at the heparin injection site. Two patients had major bleeding and five had clinically relevant non major bleeding. CONCLUSION: SCI patients are at risk of VTE and bleeding during rehabilitation. Strategies need to be developed to identify these patients in order to initiate adequate anticoagulation. Direct oral anticoagulants, which have a favourable risk-benefit profile and are convenient, should be explored. PMID- 29590127 TI - Mimicking and anticipating others' actions is linked to Social Information Processing. AB - It is widely known that individuals frequently imitate each other in social situations and that such mimicry fulfills an important social role in the sense that it functions as a social glue. With reference to the anticipated action effect, it has recently been demonstrated that individuals do not only imitate others, but also engage in anticipated action before the observed person starts engaging in that action. Interestingly, both phenomena (i.e., mimicry and anticipated action) rely on tracking others' social behavior. Therefore, in the present research we investigated whether mimicry and anticipated action are related to social abilities as indicated by measures of social intelligence. The results demonstrate for the first time that mimicry as well as anticipated action is correlated with an important aspect of social intelligence-namely the ability to process social information. Theoretical implications and limitations are discussed. PMID- 29590128 TI - Osthole inhibits gastric cancer cell proliferation through regulation of PI3K/AKT. AB - Osthole is an active compound isolated from Chinese herb Cnidium monnieri (L.) Cusson, and had been reported to possess antitumor effect. However, the effect of osthole on the gastric cancer cells has not been investigated. In this study, the effects of osthole on the proliferation of human gastric cancer cells were tested. The data showed that osthole treatment significantly inhibited the proliferation of gastric cancer cells and resulted in the cell cycle arrest at G2/M phase in a dose-dependent manner. Western-blot study showed that the expression of cyclin B1 and cdc2 was markedly reduced by osthole. Moreover, expression of PI3K and pAKT was also significantly suppressed, and the results indicated that the inhibition of pAKT, cyclin B1, and cdc2 levels by osthole was notably enhanced by a PI3K inhibitor. These results demonstrate that osthole could inhibit gastric cancer cells proliferation via induction of cell cycle arrest at G2/M phase by the reduction of PI3K/AKT. PMID- 29590129 TI - Humanin (HN) and glucose transporter 8 (GLUT8) in pregnancies complicated by intrauterine growth restriction. AB - BACKGROUND: Intrauterine growth restriction (IUGR) results from a lack of nutrients transferred to the developing fetus, particularly oxygen and glucose. Increased expression of the cytoprotective mitochondrial peptide, humanin (HN), and the glucose transporter 8, GLUT8, has been reported under conditions of hypoxic stress. However, the presence and cellular localization of HN and GLUT8 in IUGR-related placental pathology remain unexplored. Thus, we undertook this study to investigate placental expression of HN and GLUT8 in IUGR-affected versus normal pregnancies. RESULTS: We found 1) increased HN expression in human IUGR affected pregnancies on the maternal aspect of the placenta (extravillous trophoblastic (EVT) cytoplasm) compared to control (i.e. appropriate for gestational age) pregnancies, and a concomitant increase in GLUT8 expression in the same compartment, 2) HN and GLUT8 showed a protein-protein interaction by co immunoprecipitation, 3) elevated HN and GLUT8 levels in vitro under simulated hypoxia in human EVT cells, HTR8/SVneo, and 4) increased HN expression but attenuated GLUT8 expression in vitro under serum deprivation in HTR8/SVneo cells. CONCLUSIONS: There was elevated HN expression with cytoplasmic localization to EVTs on the maternal aspect of the human placenta affected by IUGR, also associated with increased GLUT8 expression. We found that while hypoxia increased both HN and GLUT8, serum deprivation increased HN expression alone. Also, a protein-protein interaction between HN and GLUT8 suggests that their interaction may fulfill a biologic role that requires interdependency. Future investigations delineating molecular interactions between these proteins are required to fully uncover their role in IUGR-affected pregnancies. PMID- 29590130 TI - Private sector tuberculosis prevention in the US: Characteristics associated with interferon-gamma release assay or tuberculin skin testing. AB - OBJECTIVE: To determine whether latent tuberculosis infection risk factors are associated with an increased likelihood of latent tuberculosis infection testing in the US private healthcare sector. DATA SOURCE: A national sample of medical and pharmacy claims representing services rendered January 2011 through December 2013 for 3,997,986 commercially insured individuals in the US who were 0 to 64 years of age. STUDY DESIGN: We used multivariable logistic regression models to determine whether TB/LTBI risk factors were associated with an increased likelihood of Interferon-Gamma Release Assay (IGRA) or Tuberculin Skin Test (TST) testing in the private sector. PRINCIPAL FINDINGS: 4.31% (4.27-4.34%) received at least one TST/IGRA test between 2011 and 2013 while 1.69% (1.67-1.72%) received a TST/IGRA test in 2013. Clinical risk factors associated with a significantly increased likelihood of testing included HIV, immunosuppressive therapy, exposure to tuberculosis, a history of tuberculosis, diabetes, tobacco use, end stage renal disease, and alcohol use disorder. Other significant variables included gender, age, asthma, the state tuberculosis rate, population density, and percent of foreign-born persons in a county. CONCLUSIONS: Private sector TST/IGRA testing is not uncommon and testing varies with clinical risk indicators. Thus, the private sector can be a powerful resource in the fight against tuberculosis. Analyses of administrative data can inform how best to leverage private sector healthcare toward tuberculosis prevention activities. PMID- 29590131 TI - Peer-to-peer lending and bias in crowd decision-making. AB - Peer-to-peer lending is hypothesized to help equalize economic opportunities for the world's poor. We empirically investigate the "flat-world" hypothesis, the idea that globalization eventually leads to economic equality, using crowdfinancing data for over 660,000 loans in 220 nations and territories made between 2005 and 2013. Contrary to the flat-world hypothesis, we find that peer to-peer lending networks are moving away from flatness. Furthermore, decreasing flatness is strongly associated with multiple variables: relatively stable patterns in the difference in the per capita GDP between borrowing and lending nations, ongoing migration flows from borrowing to lending nations worldwide, and the existence of a tie as a historic colonial. Our regression analysis also indicates a spatial preference in lending for geographically proximal borrowers. To estimate the robustness for these patterns for future changes, we construct a network of borrower and lending nations based on the observed data. Then, to perturb the network, we stochastically simulate policy and event shocks (e.g., erecting walls) or regulatory shocks (e.g., Brexit). The simulations project a drift towards rather than away from flatness. However, levels of flatness persist only for randomly distributed shocks. By contrast, loss of the top borrowing nations produces more flatness, not less, indicating how the welfare of the overall system is tied to a few distinctive and critical country-pair relationships. PMID- 29590133 TI - The effect of pond dyes on oviposition and survival in wild UK Culex mosquitoes. AB - British Culex pipiens complex [Culex pipiens sensu lato) mosquito distribution, abundance, and potential for disease transmission are intimately linked to their environment. Pond and lake dyes that block light to restrict algal photosynthesis are a relatively new product assumed to be an environmentally friendly since they are based on food dyes. Their use in urban garden ponds raises questions linked to mosquito oviposition, since coloured water can be an attractant. Culex (mostly pipiens) is commonly found in UK gardens and is a potential vector of viruses including the West Nile Virus (WNV). Any factors that significantly change the distribution and population of Cx pipiens could impact future risks of disease transmission. A gravid trap was used to catch female Cx pipiens mosquitoes for use in oviposition choice tests in laboratory and semi-field conditions. Two types of pond dye, blue and shadow (which looks slightly red), were tested for their impact on oviposition and survival of wild caught Cx pipiens. There were no significant differences in the number of egg batches laid when gravid mosquitoes were given a choice between either blue dye and clear water or shadow dye and clear water indicating that these dyes are not attractants. Larvae hatched from egg batches laid by wild-caught gravid females were used to measure survival to adulthood with or without dye, in a habitat controlled to prevent further colonisation. The experiment was run twice, once in the summer and again in the autumn, whereas the dyes had no impact on emergence in the summer, there were highly significant reductions in emergence of adults in both dye treated habitats in the autumn. Containers with or without shadow dye were placed outside to colonise naturally and were sampled weekly for larvae and pupae over a 6 month period through summer and autumn. There was a significant negative effect of shadow dye on pupal abundance in a three week period over the summer, but otherwise there was no effect. It is likely that population abundance and food was a more powerful factor for mosquito survival than the dye. PMID- 29590132 TI - GLP-1 receptor agonist ameliorates obesity-induced chronic kidney injury via restoring renal metabolism homeostasis. AB - Increasing evidence indicates that obesity is highly associated with chronic kidney disease (CKD). GLP-1 receptor (GLP-1R) agonist has shown benefits on kidney diseases, but its direct role on kidney metabolism in obesity is still not clear. This study aims to investigate the protection and metabolic modulation role of liraglutide (Lira) on kidney of obesity. Rats were induced obese by high fat diet (HFD), and renal function and metabolism changes were evaluated by metabolomic, biological and histological methods. HFD rats exhibited systemic metabolic disorders such as obesity, hyperlipidemia and impaired glucose tolerance, as well as renal histological and function damages, while Lira significantly ameliorated these adverse effects in HFD rats. Metabolomic data showed that Lira directly reduced renal lipids including fatty acid residues, cholesterol, phospholipids and triglycerides, and improved mitochondria metabolites such as succinate, citrate, taurine, fumarate and nicotinamide adenine dinucleotide (NAD+) in the kidney of HFD rats. Furthermore, we revealed that Lira inhibited renal lipid accumulation by coordinating lipogenic and lipolytic signals, and partly rescued renal mitochondria function via Sirt1/AMPK/PGC1alpha pathways in HFD rats. This study suggested that Lira alleviated HFD-induced kidney injury at least partly via directly restoring renal metabolism, thus GLP-1R agonist is a promising therapy for obesity-associated CKD.

AB - Multiple sclerosis is a chronic, progressive, and common disease affecting the central nervous system in young adults. Interferon-beta is one of the most widely used medicines to reduce the disease progression. Given the variety of drugs in this category, we aimed to identify the preferences of patients for IFN-beta that play an important role in policymaking in this area. Discrete choice experiment method was used in the present study to identify and prioritize those attributes that are of interest to MS patients and increases the utility of the use of IFN beta in their treatment. Questionnaires were given to 358 patients in Isfahan Iran, who were asked to choose between the two treatment choices in each scenario. The results of the logit model showed that the changes in the efficacy lead to the most changes in the patient utility. Changes in side effects and ease of injection have been placed in the next rankings. Considering the drug attributes considered more desirable by patients can lead to greater medication adherence and possibly better treatment outcomes. Also, pharmaceutical companies, the health ministry, the Food and Drug Administration, insurance organizations, and neurologists can benefit from this information in production and importation, policymaking, and prescription. PMID- 29590135 TI - A myeloperoxidase precursor, pro-myeloperoxidase, is present in human plasma and elevated in cardiovascular disease patients. AB - Myeloperoxidase (MPO)-derived oxidants have emerged as a key contributor to tissue damage in inflammatory conditions such as cardiovascular disease. Pro myeloperoxidase (pro-MPO), an enzymatically active precursor of myeloperoxidase (MPO), is known to be secreted from cultured bone marrow and promyelocytic leukemia cells, but evidence for the presence of pro-MPO in circulation is lacking. In the present study, we used a LC-MS/MS in addition to immunoblot analyses to show that pro-MPO is present in human blood plasma. Furthermore, we found that pro-MPO was more frequently detected in plasma from patients with myocardial infarction compared to plasma from control donors. Our study suggests that in addition to mature MPO, circulating pro-MPO may cause oxidative modifications of proteins thereby contributing to cardiovascular disease. PMID- 29590136 TI - Alveolar leak develops by a rich-get-richer process in ventilator-induced lung injury. AB - Acute respiratory distress syndrome (ARDS) is a life-threatening condition for which there are currently no medical therapies other than supportive care involving the application of mechanical ventilation. However, mechanical ventilation itself can worsen ARDS by damaging the alveolocapillary barrier in the lungs. This allows plasma-derived fluid and proteins to leak into the airspaces of the lung where they interfere with the functioning of pulmonary surfactant, which increases the stresses of mechanical ventilation and worsens lung injury. Once such ventilator-induced lung injury (VILI) is underway, managing ARDS and saving the patient becomes increasingly problematic. Maintaining an intact alveolar barrier thus represents a crucial management goal, but the biophysical processes that perforate this barrier remain incompletely understood. To study the dynamics of barrier perforation, we subjected initially normal mice to an injurious ventilation regimen that imposed both volutrauma (overdistension injury) and atelectrauma (injury from repetitive reopening of closed airspaces) on the lung, and observed the rate at which macromolecules of various sizes leaked into the airspaces as a function of the degree of overall injury. Computational modeling applied to our findings suggests that perforations in the alveolocapillary barrier appear and progress according to a rich-get richer mechanism in which the likelihood of a perforation getting larger increases with the size of the perforation. We suggest that atelectrauma causes the perforations after which volutrauma expands them. This mechanism explains why atelectrauma appears to be essential to the initiation of VILI in a normal lung, and why atelectrauma and volutrauma then act synergistically once VILI is underway. PMID- 29590137 TI - Linking hard and soft traits: Physiology, morphology and anatomy interact to determine habitat affinities to soil water availability in herbaceous dicots. AB - BACKGROUND AND AIMS: Species' habitat affinities along environmental gradients should be determined by a combination of physiological (hard) and morpho anatomical (soft) traits. Using a gradient of soil water availability, we address three questions: How well can we predict habitat affinities from hard traits, from soft traits, and from a combination of the two? How well can we predict species' physiological responses to drought (hard traits) from their soft traits? Can we model a causal sequence as soft traits -> hard traits -> species distributions? METHODS: We chose 25 species of herbaceous dicots whose affinities for soil moisture have already been linked to 5 physiological traits (stomatal conductance and net photosynthesis measured at soil field capacity, water use efficiency, stomatal conductance and soil water potential measured when leaves begin to wilt). Under controlled conditions in soils at field capacity, we measured five soft traits (leaf dry matter content, specific leaf area, leaf nitrogen content, stomatal area, specific root length). KEY RESULTS: Soft traits alone were poor predictors (R2 = 0.129) while hard traits explained 48% of species habitat affinities. Moreover, hard traits were significantly related to combinations of soft traits. From a priori biological knowledge and hypothesized ecological links we built a path model showing a sequential pattern soft traits > hard traits -> species distributions and accounting for 59.6% (p = 0.782) of habitat wetness. CONCLUSIONS: Both direct and indirect causal relationships existed between soft traits, hard traits and species' habitat preferences. The poor predictive abilities of soft traits alone were due to the existence of antagonistic and synergistic direct and indirect effects of soft traits on habitat preferences mediated by the hard traits. To obtain a more realistic model applicable to a population level, it has to be tested in an experiment including species competition for water supply. PMID- 29590138 TI - Effect of multiple drug resistance on total medical costs among patients with intra-abdominal infections in China. AB - BACKGROUND: Multiple drug resistant (MDR) intra-abdominal infections (IAIs) are associated with notable direct and societal costs. As previous studies have not considered the impact of MDR on the total medical costs (TMCs) of IAIs, the present one examines this, as well as further estimates the additional costs at a national level. METHODS: This is a retrospective study. Firstly, we randomly selected a sample of 40% of all inpatients discharged between 2014 and 2015 from a teaching hospital, due to limits in budget and the large number of patients. Then, we manually selected 254 patients with IAIs according to the International Classification of Disease, 10th revision, using electronic medical records. Eventually, 101 patients with IAIs (64 MDR patients and 37 non-MDR patients) were included after excluding cases without laboratory test results, any pathogens detected, or antimicrobial resistant pathogens. Univariate analysis and a generalized linear model were applied to assess the parameters associated with TMCs. RESULTS: Compared to non-MDR patients, those with MDR pathogens were significantly associated with higher TMCs, higher antimicrobial costs, higher antimicrobial usage, larger number of pathogens, and longer length of stay and were more likely to have insurance and combination antimicrobial therapy. In addition, the average TMC among patients with MDR pathogens was Y 131801, which is Y 90201 higher than those without MDR pathogens. If our results are applied to the whole country, the sum of all attributable TMCs was Y 37 billion. The societal costs, furthermore, were Y111 billion in 2015. CONCLUSION: Our results provide information that should lead to increased efforts to reduce inappropriate antimicrobial therapy, in order to decrease the emergence of MDR pathogens and to reduce their economic burden. PMID- 29590139 TI - The effects of unilateral and bilateral eccentric overload training on hypertrophy, muscle power and COD performance, and its determinants, in team sport players. AB - The study aimed to compare the chronic eccentric-overload training effects of unilateral (lateral lunge) vs bilateral (half-squat) using an inertial device, on hypertrophy and physical performance. Twenty-seven young team sports male players performed a 4 sets of 7 repetitions of inertial eccentric overload training, biweekly for 6 weeks, distributed in unilateral lunge group (UG: age: 22.8 +/- 2.9 years; body mass: 75.3 +/- 8.8 kg; height: 177.3 +/- 3.7 cm) and bilateral squat group (BG: age: 22.6 +/- 2.7 years; body mass: 79.5 +/- 12.8 kg; height: 164.2 +/- 7 cm). Lower limb muscle volume, counter movement jump (CMJ), power with both (POWER), dominant (POWERd) and no-dominant leg (POWERnd), change of direction turn of 90 degrees with dominant (COD90d) and no-dominant leg (COD90nd) and 180 degrees (COD180d and COD180nd), and 10m sprint time (T-10m) were measured pre and post-intervention. The UG obtained an increase of adductor major (+11.1%) and vastus medialis (+12.6%) higher than BG. The BG obtained an increase of vastus lateralis (+9.9%) and lateral gastrocnemius (+9.1%) higher than UG. Both groups improved CMJ, POWER, POWERd, POWERnd, COD90 and DEC-COD90, without changes in T-10m. The UG decrease DEC-COD90nd (-21.1%) and BG increase POWER (+38.6%) substantially more than the other group. Six-weeks of unilateral / bilateral EO training induce substantial improvements in lower limbs muscle volume and functional performance, although unilateral training seems to be more effective in improving COD90 performance. PMID- 29590140 TI - Understanding the effects of predictability, duration, and spatial pattern of drying on benthic invertebrate assemblages in two contrasting intermittent streams. AB - In the present study, we examined the effects of different drying conditions on the composition, structure and function of benthic invertebrate assemblages. We approached this objective by comparing invertebrate assemblages in perennial and intermittent sites along two intermittent Mediterranean streams with contrasting predictability, duration, and spatial patterns of drying: Fuirosos (high predictability, short duration, downstream drying pattern) and Rogativa (low predictability, long duration, patchy drying pattern). Specifically, we quantified the contribution of individual taxa to those differences, the degree of nestedness, and shifts in the composition, structure and function of benthic invertebrate assemblages along flow intermittence gradients. We observed greater effects of drying on the benthic invertebrate composition in Fuirosos than in Rogativa, resulting in a higher dissimilarity of assemblages between perennial and intermittent sites, as well as a lower degree of nestedness. Furthermore, a higher number of biotic metrics related to richness, abundance and biological traits were significantly different between perennial and intermittent sites in Fuirosos, despite a shorter dry period compared to Rogativa. At the same time, slightly different responses were detected during post-drying (autumn) than pre drying (spring) conditions in this stream. In Rogativa, shifts in benthic invertebrate assemblages along increasing gradients of flow intermittence were found for three metrics (Ephemeroptera, Plecoptera and Trichoptera (EPT) and Odonata, Coleoptera and Heteroptera (OCH) abundances and aerial active dispersal. Furthermore, we demonstrated that combined gradients of dry period duration and distance to nearest perennial reach can generate complex, and different, responses of benthic invertebrate assemblages, depending on the flow intermittence metric. Our study advances the notion that special attention should be paid to the predictability, duration and spatial patterns of drying in intermittent streams in order to disentangle the effects of drying on benthic invertebrate assemblages, in particular in areas subject to high spatial heterogeneity and temporal variability in drying conditions. PMID- 29590141 TI - Length of hospitalization and mortality for bleeding during treatment with warfarin, dabigatran, or rivaroxaban. AB - BACKGROUND: Different outcomes among patients hospitalized for bleeding after starting anticoagulation could influence choice of anticoagulant. We compared length of hospitalization, proportion of Intensive Care Unit (ICU) admissions, ICU length of stay, and 30- and 90-day mortality for adults with atrial fibrillation hospitalized for bleeding after starting warfarin, dabigatran, or rivaroxaban. METHODS: An US commercial database of 38 million members from 1 November 2010 to 31 March 2014 was used to examine adults with atrial fibrillation hospitalized for bleeding after starting warfarin (2,446), dabigatran (442), or rivaroxaban (256). Outcomes included difference in mean total length of hospitalization, proportion of ICU admissions, mean length of ICU stay, and all-cause 30- and 90-day mortality. RESULTS: Warfarin users were older and had more comorbidities. Multivariable regression modeling with propensity score weighting showed warfarin users were hospitalized 2.0 days longer (95% CI 1.8-2.3; p < 0.001) than dabigatran users and 2.6 days longer (95% CI 2.4-2.9; p < 0.001) than rivaroxaban users. Dabigatran users were hospitalized 0.6 days longer (95% CI 0.2-1.0; p = 0.001) than rivaroxaban users. There were no differences in the proportion of ICU admissions. Among ICU admissions, warfarin users stayed 3.0 days (95% CI 1.9-3.9; p < 0.001) longer than dabigatran users and 2.4 days longer (95% CI 0.9-3.7; p = 0.003) than rivaroxaban users. There was no difference in ICU stay between dabigatran and rivaroxaban users. There were no differences in 30- and 90-day all-cause mortality. CONCLUSIONS: Rivaroxaban and dabigatran were associated with shorter hospitalizations; however, there were no differences in 30- and 90-day mortality. These findings suggest bleeding associated with the newer agents is not more dangerous than bleeding associated with warfarin. PMID- 29590142 TI - Sunscreen use optimized by two consecutive applications. AB - Sunscreen users are often inadequately protected and become sunburned. This study aimed to investigate how much two consecutive sunscreen applications increased the quantity of sunscreen applied and decreased the skin area left without sunscreen (missed area) compared to a single application. Thirty-one healthy volunteers wearing swimwear were included and applied sunscreen two consecutive times in a laboratory environment. Participants had pictures taken in black light before and after each application. As sunscreens absorb black light, the darkness of the skin increased with increasing amounts of sunscreen applied. We conducted a standard curve establishing a link between change in picture darkness and quantity of sunscreen. The quantity of sunscreen at selected skin sites as well as the percentage of missed area was determined after each application. Participants had missed a median of 20% of their available body surface after a single application. After double application they had missed 9%. The decrease in missed areas was significant for the whole body surface and for each of the body regions separately. The median participant had applied between 13% and 100% more sunscreen at the selected skin sites after double application than after single application. We recommend double application, especially before intense sun exposure. PMID- 29590143 TI - Short term evaluation of respiratory effort by premature infants supported with bubble nasal continuous airway pressure using Seattle-PAP and a standard bubble device. AB - BACKGROUND: Almost one million prematurely born infants die annually from respiratory insufficiency, predominantly in countries with limited access to respiratory support for neonates. The primary hypothesis tested in the present study was that a modified device for bubble nasal continuous positive airway pressure (Bn-CPAP) would provide lower work of spontaneous breathing, estimated by esophageal pressure-rate products. METHODS: Infants born <32 weeks gestation and stable on Bn-CPAP with FiO2 <0.30 were studied within 72 h following delivery. Esophageal pressures during spontaneous breathing were measured during 2 h on standard Bn-CPAP, then 2 h with Bn-CPAP using a modified bubble device presently termed Seattle-PAP, which produces a different pattern of pressure fluctuations and which provided greater respiratory support in preclinical studies, then 2 h on standard Bn-CPAP. RESULTS: All 40 infants enrolled completed the study and follow-up through 36 wks post menstrual age or hospital discharge, whichever came first. No infants were on supplemental oxygen at completion of follow-up. No infants developed pneumothoraces or nasal trauma, and no adverse events attributed to the study were observed. Pressure-rate products on the two devices were not different, but effort of breathing, assessed by areas under esophageal pressure-time curves, was lower with Seattle-PAP than with standard Bn CPAP. CONCLUSION: Use of Seattle-PAP to implement Bn-CPAP lowers the effort of breathing exerted even by relatively healthy spontaneously breathing premature neonates. Whether the lower effort of breathing observed with Seattle-PAP translates to improvements in neonatal mortality or morbidity will need to be determined by studies in appropriate patient populations. PMID- 29590144 TI - Administration of growth factors promotes salisphere formation from irradiated parotid salivary glands. AB - Worldwide, 500,000 cases of head and neck cancer (HNC) are reported each year and the primary treatment for HNC is radiotherapy. Although the goal of radiotherapy is to target the tumor, secondary exposure occurs in surrounding normal tissues, such as the salivary glands. As a result, despite successful treatment of the cancer, patients are left with long-term side effects due to direct damage to the salivary glands. The effect is chronic and currently there is no treatment. Stem cells are an attractive therapeutic option for treatment of radiation-induced glandular dysfunction because of the potential to regenerate damaged cell populations and restore salivary gland function. However, limited knowledge about the endogenous stem cell population post irradiation hinders the development for stem cell-based therapies. In this study, an ex vivo sphere formation cell culture system was utilized to assess the self-renewal capacity of cells derived from parotid salivary glands at a chronic time point following radiation. Salivary glands from irradiated mice generate significantly fewer salispheres, but can be stimulated with fetal bovine serum (FBS) to generate an equivalent number of salispheres as unirradiated salivary glands. Interestingly, the number and size of salispheres formed is dependent on the concentration of FBS supplemented into the media. Salispheres derived from irradiated glands and cultured in FBS media were found to contain cells that proliferate and express progenitor and acinar cell markers such as Keratin 5, Keratin 14, Aquaporin 5, and NKCC1. Utilization of insulin-like growth factor (IGF1) injections following radiation treatment restores salivary gland function and improves salisphere generation. These findings indicate that stimulation of these cellular populations may provide a promising avenue for the development of cell-based therapies for radiation-induced salivary gland damage. PMID- 29590145 TI - Genomic profiling of bovine corpus luteum maturation. AB - To unveil novel global changes associated with corpus luteum (CL) maturation, we analyzed transcriptome data for the bovine CL on days 4 and 11, representing the developing vs. mature gland. Our analyses revealed 681 differentially expressed genes (363 and 318 on day 4 and 11, respectively), with >=2 fold change and FDR of <5%. Different gene ontology (GO) categories were represented prominently in transcriptome data at these stages (e.g. days 4: cell cycle, chromosome, DNA metabolic process and replication and on day 11: immune response; lipid metabolic process and complement activation). Based on bioinformatic analyses, select genes expression in day 4 and 11 CL was validated with quantitative real-time PCR. Cell specific expression was also determined in enriched luteal endothelial and steroidogenic cells. Genes related to the angiogenic process such as NOS3, which maintains dilated vessels and MMP9, matrix degrading enzyme, were higher on day 4. Importantly, our data suggests day 11 CL acquire mechanisms to prevent blood vessel sprouting and promote their maturation by expressing NOTCH4 and JAG1, greatly enriched in luteal endothelial cells. Another endothelial specific gene, CD300LG, was identified here in the CL for the first time. CD300LG is an adhesion molecule enabling lymphocyte migration, its higher levels at mid cycle are expected to support the transmigration of immune cells into the CL at this stage. Together with steroidogenic genes, most of the genes regulating de-novo cholesterol biosynthetic pathway (e.g HMGCS, HMGCR) and cholesterol uptake from plasma (LDLR, APOD and APOE) were upregulated in the mature CL. These findings provide new insight of the processes involved in CL maturation including blood vessel growth and stabilization, leucocyte transmigration as well as progesterone synthesis as the CL matures. PMID- 29590146 TI - The impact of pharmacists-led medicines reconciliation on healthcare outcomes in secondary care: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Adverse drug events (ADEs) impose a major clinical and cost burden on acute hospital services. It has been reported that medicines reconciliation provided by pharmacists is effective in minimizing the chances of hospital admissions related to adverse drug events. OBJECTIVE: To update the previous assessment of pharmacist-led medication reconciliation by restricting the review to randomized controlled trials (RCTs) only. METHODS: Six major online databases were sifted up to 30 December 2016, without inception date (Embase, Medline Ovid, PubMed, BioMed Central, Web of Science and Scopus) to assess the effect of pharmacist-led interventions on medication discrepancies, preventable adverse drug events, potential adverse drug events and healthcare utilization. The Cochrane tool was applied to evaluate the chances of bias. Meta-analysis was carried out using a random effects model. RESULTS: From 720 articles identified on initial searching, 18 RCTs (6,038 patients) were included. The quality of the included studies was variable. Pharmacists-led interventions led to an important decrease in favour of the intervention group, with a pooled risk ratio of 42% RR 0.58 (95% CI 0.49 to 0.67) P<0.00001 in medication discrepancy. Reductions in healthcare utilization by 22% RR 0.78 (95% CI 0.61 to 1.00) P = 0.05, potential ADEs by10% RR 0.90 (95% CI 0.78 to 1.03) P = 0.65 and preventable ADEs by 27% RR 0.73 (0.22 to 2.40) P = 0.60 were not considerable. CONCLUSION: Pharmacists-led interventions were effective in reducing medication discrepancies. However, these interventions did not lead to a significant reduction in potential and preventable ADEs and healthcare utilization. PMID- 29590147 TI - Influence of bone-conducted vibration on simulator sickness in virtual reality. AB - Use of virtual reality (VR) technology is often accompanied by a series of unwanted symptoms, including nausea and headache, which are characterised as 'simulator sickness'. Sensory mismatch has been thought to lie at the heart of the problem and recent studies have shown that reducing cue mismatch in VR can have a therapeutic effect. Specifically, electrical stimulation of vestibular afferent nerves (galvanic vestibular stimulation; GVS) can reduce simulator sickness in VR. However, GVS poses a risk to certain populations and can also result in negative symptoms in normal, healthy individuals. Here, we tested whether noisy vestibular stimulation through bone-vibration can also reduce symptoms of simulator sickness. We carried out two experiments in which participants performed a spatial navigation task in VR and completed the Simulator Sickness Questionnaire over a series of trials. Experiment 1 was conducted using a high-end projection-based VR display, whereas Experiment 2 involved the use of a consumer head mounted display. During each trial, vestibular stimulation was either: 1) absent; 2) coupled with large angular accelerations of the projection camera; or 3) applied randomly throughout each trial. In half of the trials, participants actively navigated using a motion controller, and in the other half they were moved passively through the environment along pre-recorded motion trajectories. In both experiments we obtained lower simulator sickness scores when vestibular stimulation was coupled with angular accelerations of the camera. This effect was obtained for both active and passive movement control conditions, which did not differ. The results suggest that noisy vestibular stimulation can reduce simulator sickness, and that this effect appears to generalize across VR conditions. We propose further examination of this stimulation technique. PMID- 29590148 TI - Gender, nutritional status and disability-free life expectancy among older people in Santiago, Chile. AB - BACKGROUND: This study was aimed to estimate life expectancy (LE), disability free life expectancy (DFLE) and disabled life expectancy (DLE) among older adults from Santiago, Chile, and to determine the existence of differences by gender and by body mass index (BMI) categories in these indicators. METHODS: A sample of 1216 people aged 60 or more, from the Chilean cohort of the Study of Health, Ageing and Well-Being was recruited in 2000; two follow-up assessments were carried out in a 10-year period. Functional limitation was assessed through self report of difficulties in activities of daily living, instrumental activities of daily living and mobility. BMI was determined with measured weight and height. Multistate life tables were employed to estimate LE and healthy life expectancy (HLE). RESULTS: At 60 years, women could expect to live on average an additional 20.4 years (95% CI 19.0-21.6), and men an additional 16.4 years (95% CI 14.9 17.7). Total LE was longer among women at all ages, but they had a higher proportion of disabled years to be lived compared to men, with a difference of 14% at 60 years, and 10% at 90 years. There were no significant differences in LE, DFLE and DLE between BMI categories. DISCUSSION: Despite a longer LE, Chilean older women expect to live a higher proportion of years with disabilities, compared to men. Public health programs should address factors affecting LE of older men, and those associated with disability among older women. PMID- 29590149 TI - Increased ethanol consumption after interruption of fat bingeing. AB - There is a marked comorbidity between alcohol abuse and eating disorders, especially in the young population. We have previously reported that bingeing on fat during adolescence increases the rewarding effects of ethanol (EtOH). The aim of the present work was to study if vulnerability to EtOH persists after cessation of binge eating. OF1 mice binged on fat (HFB: high-fat binge) during adolescence (PND 25-43) and were tested for 15 days after the last access to HFB (on PND 59) using the self-administration paradigm, the conditioned place preference (CPP) and locomotor sensitization to ethanol. Our results showed that after 15 days of cessation of fat ingestion, mice increased their consumption of ethanol and showed greater motivation to obtain ethanol. On the other hand, no effects were observed in the CPP, while an increased locomotor response to ethanol was detected. The present results confirm and extend our previous study demonstrating that the compulsive intake of fat induces long-lasting effects on the reward system that lead to an increased consumption of EtOH. PMID- 29590150 TI - Retention in care among older adults living with HIV in western Kenya: A retrospective observational cohort study. AB - BACKGROUND: Retention, defined as continuous engagement in care, is an important indicator for quality of healthcare services. To achieve UNAIDS 90-90-90 targets, emphasis on retention as a predictor of viral suppression in patients initiated on ART is vital. Using routinely collected clinical data, the authors sought to determine the effect of age on retention post ART initiation. METHODS: De identified electronic data for 32965 HIV-infected persons aged >=15 years at enrolment into the Academic Model Providing Access to Healthcare program between January 2008 and December 2014 were analyzed. Follow-up time was defined from the date of ART initiation until either loss to follow-up or death or close of the database (September 2016) was observed. Proportions were compared using Pearson's Chi-square test and medians using Mann-Whitney U test. Logistic regression model was used to assess differences in ART initiation between groups, adjusting for baseline characteristics. Cox proportional hazards model adjusting for baseline characteristics and antiretroviral therapy (ART) status was used to compute hazard ratios. Kaplan-Meier survival function was used to compare retention on ART at 12, 24, and 36 months post ART initiation. RESULTS: Of the total sample, 3924 (12.0%) were aged >=50 years at enrolment. The median (IQR) age of young adults and older adults were 32.5 (26.6, 36.9) and 54.9 (51.7, 59.9) respectively. ART initiation rates were 70.5% among older adults and 68.2% among younger adults. Retention rates in care at 12, 24 and 36 months post ART initiation were 73.9% (95% CL: 72.2, 75.5), 62.9% (95% CL: 61.0, 64.7) and 55.4% (95% CL: 53.5, 57.3) among older adults compared to 69.8% (95% CL: 69.1, 70.4), 58.1% (95% CL: 57.4, 58.8) and 49.3% (95% CL: 48.6, 50.0) among younger adults (p <0.001). A higher proportion of older adults were retained in HIV care post ART initiation compared to younger adults, Adjusted Hazard Ratio (AHR): 0.83 (95% CI: 0.78, 0.87) though they were more likely to die, AHR: 1.35 (95% CI: 1.19, 1.52). CONCLUSION: A higher proportion of older adults are initiated on ART and have better retention in care at 12, 24 and 36 months post ART initiation than younger adults. However, older adults have a higher all-cause mortality rate, perhaps partially driven by late presentation to care. Enhanced outreach and care to this group is imperative to improve their outcomes. PMID- 29590151 TI - Untreated depression among persons living with human immunodeficiency virus in Kazakhstan: A cross-sectional study. AB - BACKGROUND: In Kazakhstan, scarce official prevalence data exists for mood disorders. This study investigates the occurrence of depressive symptoms among people living with HIV/AIDS (PLWHA), and the relationship between depressive symptoms, HIV treatment initiation and antiretroviral treatment (ART) adherence. METHODS: A cross-sectional study was conducted among patients seen at the Almaty AIDS Center between April and December 2013. Two data sources were used: 1) self administered survey that included the Patient Health Questionnaire (PHQ-9) to capture depression symptoms and 2) medical record review. Two primary outcomes were evaluated with log-binomial models and Fisher's exact test: the relationship between depression symptoms and 1) HIV treatment group, and 2) HIV adherence. RESULTS: Of the 564 participants, 9.9% reported symptoms consistent with a depressive disorder. None had received treatment for depression. Among those not on ART, a relationship between depressive symptoms and low CD4 counts (<= 350 cells/mm3) was evident (7.1% for CD4 <= 350 cells/mm3 vs. 0.9% for CD4 > 350 cells/mm3, p = 0.029). In multivariable analysis, a higher prevalence of depressive symptoms was statistically associated with ART treatment, positive hepatitis C virus (HCV) status, and being unmarried. For those taking ART, treatment adherence was not statistically associated with a lower prevalence of depressive symptoms (12.5% vs 20.0%, p = 0.176); limited power may have impacted statistical significance. CONCLUSIONS: Untreated depression was found among PLWHA suggesting the need to evaluate access to psychiatric treatment. A collaborative strategy may be helpful to optimize HIV treatment outcomes. PMID- 29590152 TI - Clinical spectrum and prognostic factors of possible UIP pattern on high resolution CT in patients who underwent surgical lung biopsy. AB - BACKGROUND: Few studies have reported the diagnostic variability in patients with a possible usual interstitial pneumonia (UIP) pattern on high-resolution CT (HRCT) who underwent surgical lung biopsy (SLB), and the prognostic factors for these patients have not been fully evaluated. We retrospectively investigated the frequency of idiopathic pulmonary fibrosis (IPF) and prognostic factors in patients with possible UIP pattern on HRCT. METHODS: Consecutive patients who had a possible UIP pattern on HRCT, underwent SLB, and had a diagnosis of IIPs before SLB were retrospectively recruited from 10 hospitals. Diagnoses were made based on multidisciplinary discussion using the criteria for current IPF guidelines and multidisciplinary classification for IIPs in each hospital. RESULTS: 179 patients who underwent SLB were enrolled. The diagnoses were IPF in 91 patients (51%), unclassifiable IIPs in 47 (26%), idiopathic NSIP in 18 (10%), and chronic hypersensitivity pneumonia in 17 (9%). One-year FVC changes showed significant differences between IPF and non-IPF (-138.6 mL versus 18.2 mL, p = 0.014). Patients with IPF had a worse mortality than those with non-IPF (Logrank test, p = 0.025). Multivariable Cox regression analysis demonstrated that diagnoses of IPF (HR, 2.961; 95% CI, 1.183-7.410; p = 0.02), high modified MRC score (HR, 1.587; 95% CI, 1.003-2.510; p = 0.049), and low %FVC (HR, 0.972; 95% CI, 0.953 0.992; p = 0.005). CONCLUSIONS: About a half of patients with a possible UIP pattern on HRCT had diagnoses other than IPF, and patients with IPF had a worse mortality than those with an alternative diagnosis. We reaffirmed that multidisciplinary discussion is crucial in patients with possible UIP pattern on HRCT.

AB - Vitellogenesis is the process of yolk formation via accumulating vitellin (Vn) with nutrients in the oocytes. Expression of vitellogenin (Vg), the precursor of Vn, is one of the indicators for the start of vitellogenesis. In Pacific white shrimp (Litopenaeus vannamei), the type-II vitellogenesis-inhibiting hormone (VIH 2) effectively suppresses hepatopancreatic Vg mRNA expression. In this study, we demonstrate the increasing transcript levels of hepatopancreatic Vg during L. vannamei ovarian development, suggesting that the hepatopancreas-derived Vg/Vn may also contribute to vitellogenesis in this species. Using a combination of in vivo injections and in vitro primary cell cultures, we provide evidences that the inhibition of VIH-2 on hepatopancreatic Vg gene expression is mediated through a functional coupling of the GC/cGMP pathway with different MAPK-dependent cascades in female shrimp. In VIH-2 signaling, the NO-independent GC/cGMP/PKG cascades were upstream of the MAPKs. Activations of the MAPK signal by VIH-2 include the phosphorylation of JNK and the mRNA/protein expression of P38MAPK. Additionally, the cAMP/PKA pathway is another positive intracellular signal for hepatopancreatic Vg mRNA expression but is independent of its VIH-2 regulation. Our findings establish a model for the signal transduction mechanism of Vg regulation by VIH and shed light on the biological functions and signaling of the CHH family in crustaceans. PMID- 29590154 TI - Na+/K+ ATPase activity promotes invasion of endocrine resistant breast cancer cells. AB - BACKGROUND: The Na+/K+-ATPase (NKP) is an important ion transporter also involved in signal transduction. Its expression profile is altered in various tumours including that of the breast. We studied the effect of inhibiting NKP activity in non-tumorigenic breast cell line and in estrogen receptor positive and negative breast cancer cells. METHODS: Expression and localization of NKP and downstream signaling molecules were determined by RT-PCR, western blotting and immunofluorescence. Cell proliferation, apoptosis and cell cycle stage were determined using MTT, annexin V and flow cytometry. Cell motility and invasion were determined using wound healing and matrigel assays. Total matrix metalloproteinase (MMP) was determined by a fluorescence-based assay. RESULTS: NKP was mainly localized on the cell membrane. Its baseline expression and activity were enhanced in breast cancer compared to the non-tumorigenic breast cell line. Ouabain and 3,4,5,6-tetrahydroxyxanthone (TTX) treatment significantly inhibited NKP activity, which significantly reduced cell proliferation, motility, invasion and pH-induced membrane blebbing. EGF stimulation induced internalization of NKP from the cell membrane to the cytoplasm. Ouabain inhibited EGF-induced phosphorylation of Rac/cdc42, profillin, ERK1/2 and P70S6K. CONCLUSIONS: The NKP may offer a novel therapeutic target in breast cancer patients who have developed metastasis, aiming to improve therapeutic outcomes and enhance survival rate. PMID- 29590155 TI - Unravelling biocultural population structure in 4th/3rd century BC Monterenzio Vecchio (Bologna, Italy) through a comparative analysis of strontium isotopes, non-metric dental evidence, and funerary practices. AB - The 4th century BC marks the main entrance of Celtic populations in northern Italy. Their arrival has been suggested based on the presence of Celtic customs in Etruscan mortuary contexts, yet up to now few bioarchaeological data have been examined to support or reject the arrival of these newcomers. Here we use strontium isotopes, non-metric dental traits and funerary patterns to unravel the biocultural structure of the necropolis of Monterenzio Vecchio (Bologna, Italy). Subsamples of our total sample of 38 individuals were analyzed based on different criteria characterizing the following analyses: 1) strontium isotope analysis to investigate migratory patterns and provenance; 2) non-metric dental traits to establish biological relationships between Monterenzio Vecchio, 13 Italian Iron age necropolises and three continental and non-continental Celtic necropolises; 3) grave goods which were statistically explored to detect possible patterns of cultural variability. The strontium isotopes results indicate the presence of local and non-local individuals, with some revealing patterns of mobility. The dental morphology reveals an affinity between Monterenzio Vecchio and Iron Age Italian samples. However, when the Monterenzio Vecchio sample is separated by isotopic results into locals and non-locals, the latter share affinity with the sample of non-continental Celts from Yorkshire (UK). Moreover, systematic analyses demonstrate that ethnic background does not retain measurable impact on the distribution of funerary elements. Our results confirm the migration of Celtic populations in Monterenzio as archaeologically hypothesized on the basis of the grave goods, followed by a high degree of cultural admixture between exogenous and endogenous traits. This contribution shows that combining different methods offers a more comprehensive perspective for the exploration of biocultural processes in past and present populations. PMID- 29590156 TI - Factors influencing long-term medication non-adherence among diabetes and hypertensive patients in Ghana: A qualitative investigation. AB - BACKGROUND: Evidence remains limited on why diabetes and hypertensive patients admitted to long-term drug therapy miss doses or discontinue medication taking. We examined this phenomenon from the perspective of diabetes and hypertension patients at a Ghanaian teaching hospital. METHODS: Between July and December 2015, we conducted a qualitative study targeting caregivers and their patients with chronic diabetes and hypertensive on re-admission at the Korle Bu Teaching Hospital due to non-adherence to prescribed medication. Participants were sampled purposefully and taking through in-depth interviews using an interview guide. Notes and audio recordings of interviews were transcribed, managed and coded for themes guided by the thematic network analysis recommended by Attride-Stirling. RESULTS: Non-adherence was the result of perceptions that the medications are not effective for managing the conditions. Patients with these perceptions rejected the medications and turned to herbal medicines and spiritual healing as therapeutic alternatives, because of their easy accessibility, perceived efficacy and affordability. Other factors identified to influence non-adherence included polypharmacy practice; tight work schedules; social norms; poor prescription instruction by health providers; and knowledge and experience of medication. CONCLUSION: Findings suggests the need for health providers to adopt therapeutic approaches that take into account patients' beliefs, values and norms in administering medications. Sensitisation of patients and caregivers during admission on the implication of non-adherence, as well as interventions that monitor and provide feedback mechanisms on patients' medication taking behaviour holds promise for maximising diabetes and hypertensive medication adherence. PMID- 29590157 TI - Hyperopic refractive correction by LASIK, SMILE or lenticule reimplantation in a non-human primate model. AB - Hyperopia is a common refractive error, apparent in 25% of Europeans. Treatments include spectacles, contact lenses, laser interventions and surgery including implantable contact lenses and lens extraction. Laser treatment offers an expedient and reliable means of correcting ametropia. LASIK is well-established however SMILE (small-incision lenticule extraction) or lenticule implantation (derived from myopic laser-correction) are newer options. In this study we compared the outcomes of hyperopic LASIK, SMILE and lenticule re-implantation in a primate model at +2D/+4D treatment. While re-implantation showed the greatest regression, broadly comparable refractive results were seen at 3-months with SMILE and LASIK (<1.4D of intended), but a greater tendency to regression in +2D lenticule reimplantation. Central corneal thickness showed greater variation at +2D treatment, but central thickening during lenticule reimplantation at +4D treatment was seen (-17+/- 27MUm LASIK, -45 +/- 18MUm SMILE and 28 +/- 17MUm Re implantation; p <0.01) with expected paracentral thinning following SMILE. Although in vivo confocal microscopy appeared to show higher reflectivity in all +4D treatment groups, there were minimal and inconsistent changes in inflammatory responses between modalities. SMILE and lenticule re-implantation may represent a safe and viable method for treating hyperopia, but further optimization for lower hyperopic treatments is warranted. PMID- 29590158 TI - Significance of serological markers in the disease course of ulcerative colitis in a prospective clinical cohort of patients. AB - BACKGROUND & AIMS: To determine the prognostic potential of classic and novel serologic antibodies regarding unfavorable disease course in a prospective ulcerative colitis (UC) patient cohort, since few and conflicting data are available in the literature regarding this matter. METHODS: 187 consecutive patients were studied prospectively (median follow-up: 135 months) from a single referral IBD center in Hungary. Sera were tested for different IgA/IgG type autoantibodies (anti-neutrophil cytoplasmic [ANCA], anti-DNA-bound-lactoferrin [anti-LFS], anti-goblet cell [anti-GAB] and anti-pancreatic [PAB: anti-CUZD1 and anti-GP2)]) by indirect immunofluorescence technique and for anti-microbial (anti Saccharomyces cerevisiae [ASCA] IgG/IgA and anti-OMP PlusTM IgA) antibodies by enzyme-linked immunosorbent assays. RESULTS: A total of 73.6%, 62.4% and 11.2% of UC patients were positive for IgA/IgG type of atypical perinuclear-ANCA, anti-LFS and anti-GAB, respectively. Occurrences of PABs were 9.6%, while ASCA IgA/IgG and anti-OMP IgA were 17.6% and 19.8%, respectively. Antibody status was stable over time. IgA type PABs were more prevalent in patients with primary sclerosing cholangitis (37.5% vs. 4.7% for anti-CUZD1 and 12.5% vs. 0% for anti-GP2, p<0.001 for both). IgA type ASCA and anti-CUZD1 antibodies were associated with higher risk of requirement for long-term immunosuppressant therapy in Kaplan-Meier analysis (pLogRank <0.01 for both). However, in multivariate Cox-regression analysis only ASCA IgA (HR: 2.74, 95%CI: 1.46-5.14, p<0.01) remained independent predictor. UC-related hospitalization due to disease activity was only associated with multiple antibody positivity (for 3 or more; HR 2.03 [95% CI: 1.16-3.56]; p = 0.013). None of the individual antibodies or their combination was associated with the risk of development of extensive disease or colectomy. CONCLUSION: Even with low prevalence rates, present study gives further evidence to the role of certain antibodies as markers for distinct phenotype and disease outcome in UC. Considering the result of the multivariate analysis the novel antibodies investigated do not seem to be associated with poor clinical outcome in UC, only a classic antibody, IgA subtype ASCA remained an independent predictor of long term immunosuppressive therapy. PMID- 29590159 TI - Motivations of women in Uganda living with rheumatic heart disease: A mixed methods study of experiences in stigma, childbearing, anticoagulation, and contraception. AB - BACKGROUND: Rheumatic heart disease (RHD) is a leading cause of premature mortality in low- and middle-income countries (LMICs). Women of reproductive age are a unique and vulnerable group of RHD patients, due to increased risk of cardiovascular complications and death during pregnancy. Yet, less than 5% of women of childbearing age with RHD in LMICs use contraceptives, and one in five pregnant women with RHD take warfarin despite known teratogenicity. It is unclear whether this suboptimal contraception and anticoagulant use during pregnancy is due to lack of health system resources, limited health literacy, or social pressure to bear children. METHODS: We conducted a mixed methods study of 75 women living with RHD in Uganda. Questionnaires were administered to 50 patients. Transcripts from three focus groups with 25 participants were analyzed using qualitative description methodology. RESULTS: Several themes emerged from the focus groups, including pregnancy as a calculated risk; misconceptions about side effects of contraceptives and anticoagulation; reproductive decision-making control by male partners, in-laws, or physicians; abandonment of patients by male partners; and considerable stigma against heart disease patients for both their reproductive and financial limitations (often worse than that directed against HIV patients). All questionnaire respondents were told by physicians that their hearts were not strong enough to support a pregnancy. Only 14% used contraception while taking warfarin. All participants felt that society would look poorly on a woman who cannot have children due to a heart condition. CONCLUSIONS: To our knowledge, this is the first qualitative study of female RHD patients and their attitudes toward cardiovascular disorders and reproduction. Our results suggest that health programs targeting heart disease in LMICs must pay special attention to the needs of women of childbearing age. There are opportunities for improved family/societal education programs and community engagement, leading to better outcomes and patient empowerment. PMID- 29590160 TI - Tissue-specific impact of FADS cluster variants on FADS1 and FADS2 gene expression. AB - Omega-6 (n-6) and omega-3 (n-3) long (>= 20 carbon) chain polyunsaturated fatty acids (LC-PUFAs) play a critical role in human health and disease. Biosynthesis of LC-PUFAs from dietary 18 carbon PUFAs in tissues such as the liver is highly associated with genetic variation within the fatty acid desaturase (FADS) gene cluster, containing FADS1 and FADS2 that encode the rate-limiting desaturation enzymes in the LC-PUFA biosynthesis pathway. However, the molecular mechanisms by which FADS genetic variants affect LC-PUFA biosynthesis, and in which tissues, are unclear. The current study examined associations between common single nucleotide polymorphisms (SNPs) within the FADS gene cluster and FADS1 and FADS2 gene expression in 44 different human tissues (sample sizes ranging 70-361) from the Genotype-Tissue Expression (GTEx) Project. FADS1 and FADS2 expression were detected in all 44 tissues. Significant cis-eQTLs (within 1 megabase of each gene, False Discovery Rate, FDR<0.05, as defined by GTEx) were identified in 12 tissues for FADS1 gene expression and 23 tissues for FADS2 gene expression. Six tissues had significant (FDR< 0.05) eQTLs associated with both FADS1 and FADS2 (including artery, esophagus, heart, muscle, nerve, and thyroid). Interestingly, the identified eQTLs were consistently found to be associated in opposite directions for FADS1 and FADS2 expression. Taken together, findings from this study suggest common SNPs within the FADS gene cluster impact the transcription of FADS1 and FADS2 in numerous tissues and raise important questions about how the inverse expression of these two genes impact intermediate molecular (such a LC-PUFA and LC-PUFA-containing glycerolipid levels) and ultimately clinical phenotypes associated with inflammatory diseases and brain health. PMID- 29590161 TI - A rat in the sewer: How mental imagery interacts with object recognition. AB - The role of mental imagery has been puzzling researchers for more than two millennia. Both positive and negative effects of mental imagery on information processing have been discussed. The aim of this work was to examine how mental imagery affects object recognition and associative learning. Based on different perceptual and cognitive accounts we tested our imagery-induced interaction hypothesis in a series of two experiments. According to that, mental imagery could lead to (1) a superior performance in object recognition and associative learning if these objects are imagery-congruent (semantically) and to (2) an inferior performance if these objects are imagery-incongruent. In the first experiment, we used a static environment and tested associative learning. In the second experiment, subjects encoded object information in a dynamic environment by means of a virtual sewer system. Our results demonstrate that subjects who received a role adoption task (by means of guided mental imagery) performed better when imagery-congruent objects were used and worse when imagery incongruent objects were used. We finally discuss our findings also with respect to alternative accounts and plead for a multi-methodological approach for future research in order to solve this issue. PMID- 29590162 TI - Clinical and epidemiological characterization of influenza virus infections in children with severe acute respiratory infection in Maputo, Mozambique: Results from the implementation of sentinel surveillance, 2014 - 2016. AB - In Sub-Saharan Africa, where burden, impact, and incidence of acute respiratory infections (ARI) are the highest in the world, conversely, the epidemiology of influenza-associated severe acute respiratory infections (SARI) is incompletely known. The aim of this study was to describe the clinical and epidemiological features of influenza-associated SARI in hospitalized children in Maputo city, Mozambique. Nasopharyngeal and oropharyngeal swabs were collected from children aged 0-14 years old who met the case definition for SARI in two hospitals in Maputo city after their parents or legal representative consented to participate. A structured questionnaire was used to collect clinical and demographic data. Typing and subtyping of influenza were performed by real-time PCR. From January 2014 to December 2016, a total of 2,007 eligible children were recruited, of whom 1,997 (99.5%) were screened for influenza by real-time PCR. The median age of participants was 16.9 months (IQR: 7.0-38.9 months) and 53.9% (1076/1991) were male. A total of 77 were positive for influenza, yielding a frequency of 3.9% (77/1,991), with the highest frequency being reported in the age group 1-5 years old. Cases of influenza peaked twice each year, during which, its frequency reached up to 60%-80%. Among all influenza confirmed cases, 33.7% (26/77), 35.1% (27/77) and 28.6% (22/77) were typed as influenza A/H3N2, A/H1N1pdm09, and B, respectively. This represents the first report of influenza in urban/sub urban setting in Mozambique and the first evidence of distribution of strains of influenza in the country. Our data showed that frequency of influenza was lower than reported in a rural setting in Mozambique and the frequency of seasonal (A/H1N1pdm09) and (A/H3N2) subtypes were similar in children with SARI. PMID- 29590164 TI - Differentiating percussion pits and carnivore tooth pits using 3D reconstructions and geometric morphometrics. AB - During the end of the 20th century and the beginning of the 21st century the discussion on early human behavioral patterns revolved around the hunting versus scavenging debate. The correct identification of bone modifications, including percussion, cut and tooth marks, is a key issue within this debate. While many authors have shown that carnivore and human modifications can be easily distinguished, it is true that sometimes percussion marks without associated microstriations and tooth pits overlap morphologically, causing confusion, especially when unmodified hammerstones are used. In order to solve this equifinality problem, many investigations have focused their efforts on other pieces of evidence such as the identification of notches, fragmentation patterns and frequencies, among others. These studies, however, cannot be considered as fully conclusive. Within this paper we address the problem of equifinality when identifying percussion marks produced with unmodified hammerstones and tooth pits created by carnivores using new methodologies based on the 3D reconstruction of marks and their statistical multivariate analysis. For the purpose of this study a total of 128 marks- 39 percussion marks produced with an unmodified quartzite hammerstone, and 89 pits generated by different carnivores-were virtually modelled with the aid of a DAVID structured-light scanner SLS-2 and later analyzed by means of geometric morphometrics. Our results show that percussion marks not associated with striae fields and the pits generated by the carnivores studied here can be successfully distinguished. PMID- 29590163 TI - Fresh red blood cells transfusion protects against aluminum phosphide-induced metabolic acidosis and mortality in rats. AB - BACKGROUND: Aluminum phosphide (AlP) is used as pesticide in some countries for protection of stored grains. Human poisoning with AlP due to suicide attempt or accidental environmental exposure is associated with very high mortality partially due to development of severe metabolic acidosis. Previous studies have shown that hemoglobin has high buffering capacity and erythrocytes can potentially be used for management of metabolic acidosis. The aim of this study was to evaluate the effect of fresh packed red blood cells (RBC) transfusion on survival and cardiovascular function in AlP-poisoned rats. METHODOLOGY/PRINCIPAL FINDINGS: Rats were poisoned with AlP by gavage. Fresh packed RBC was transfused via tail vein after AlP administration. Acid-base balance, vital signs and mortality was assessed and compared in experimental groups. Infusion of fresh packed RBC (1.5 ml) one hour after AlP (4-15 mg/kg) intoxication was associated with a significant decrease in mortality rate. Packed RBC infusion improved blood pH, HCO3-, Na+ and Ca2+ levels. Plasma troponin level was also reduced and ECG changes were reversed following packed RBC infusion in AlP intoxicated rats. CONCLUSIONS: Our results showed that fresh RBC transfusion could ameliorate metabolic acidosis and enhance survival in AlP-poisoned rat. We assume that an increase in pool of RBCs may modulate acid-base balance or potentially chelate AlP-related toxic intermediates via phosphine-hemoglobin interaction. PMID- 29590165 TI - Terminal Pleistocene epoch human footprints from the Pacific coast of Canada. AB - Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2-3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments. During subsurface testing, we uncovered human footprints impressed into a 13,000-year-old paleosol beneath beach sands at archaeological site EjTa 4. To date, our investigations at this site have revealed a total of 29 footprints of at least three different sizes. The results presented here add to the growing body of information pertaining to the early deglaciation and associated human presence on the west coast of Canada at the end of the Last Glacial Maximum. PMID- 29590166 TI - Tooth loss and risk of cardiovascular disease and stroke: A dose-response meta analysis of prospective cohort studies. AB - Conflicting results identifying the association between tooth loss and cardiovascular disease and stroke have been reported. Therefore, a dose-response meta-analysis was performed to clarify and quantitatively assess the correlation between tooth loss and cardiovascular disease and stroke risk. Up to March 2017, seventeen cohort studies were included in current meta-analysis, involving a total of 879084 participants with 43750 incident cases. Our results showed statistically significant increment association between tooth loss and cardiovascular disease and stroke risk. Subgroups analysis indicated that tooth loss was associated with a significant risk of cardiovascular disease and stroke in Asia and Caucasian. Furthermore, tooth loss was associated with a significant risk of cardiovascular disease and stroke in fatal cases and nonfatal cases. Additionally, a significant dose-response relationship was observed between tooth loss and cardiovascular disease and stroke risk. Increasing per 2 of tooth loss was associated with a 3% increment of coronary heart disease risk; increasing per 2 of tooth loss was associated with a 3% increment of stroke risk. Subgroup meta analyses in study design, study quality, number of participants and number of cases showed consistent findings. No publication bias was observed in this meta analysis. Considering these promising results, tooth loss might provide harmful health benefits. PMID- 29590167 TI - Serum vitamin D concentrations in hospitalized critically ill dogs. AB - Hypovitaminosis D has been extensively documented in critically ill humans. However, whether or not critically ill dogs have alterations in vitamin D concentrations remains unconfirmed. The primary aims of our study were to compare serum 25-hydroxycholecalciferol [25(OH)D] concentrations in critically ill dogs with healthy control dogs, determine the prognostic utility of serum 25(OH)D concentration as a biomarker in critically ill dogs, and to assess if serum 25(OH)D concentrations in critically ill dogs are associated with length of stay in the intensive care unit or illness severity. Serum concentrations of 25(OH)D together with a range of other clinical, biochemical, and hematological parameters, were measured in 99 dogs within 24 hours of admission to the Intensive Care Unit (ICU). Critically ill dogs (P = 0.001) and dogs with sepsis (P = 0.002) had significantly lower serum 25(OH)D concentrations compared to healthy control dogs. In addition, serum 25(OH)D concentration was an independent predictor of in-hospital and 30 day survival. Using a cut-off of 33 ng/mL, serum 25(OH)D concentrations had excellent sensitivity (0.94; 95% CI, 0.71-1.00), but poor specificity (0.41; 95% CI, 0.31-0.53) for detection of survival. Serum 25(OH)D concentrations were inversely associated with acute patient physiologic and laboratory evaluation (APPLE) fast score but were not associated with ICU length of stay. Hospitalized dogs with critical illness have decreased serum 25(OH)D concentrations compared to healthy dogs and can be used to predict survival in this cohort. PMID- 29590168 TI - Just ask Siri? A pilot study comparing smartphone digital assistants and laptop Google searches for smoking cessation advice. AB - OBJECTIVE: To compare voice-activated internet searches by smartphone (two digital assistants) with laptop ones for information and advice related to smoking cessation. DESIGN: Responses to 80 questions on a range of topics related to smoking cessation (including the FAQ from a NHS website), compared for quality. SETTING: Smartphone and internet searches as performed in New Zealand. MAIN OUTCOME MEASURES: Ranked responses to the questions. RESULTS: Google laptop internet searches came first (or first equal) for best quality smoking cessation advice for 83% (66/80) of the responses. Voiced questions to Google Assistant ("OK Google") came first/first equal 76% of the time vs Siri (Apple) at 28%. Google and Google Assistant were statistically significantly better than Siri searches (odds ratio 12.4 and 8.5 respectively, p<0.0001 in each comparison). When asked FAQs from the National Health Service website, or to find information the Centers for Disease Control has made videos on, the best search results used expert sources 59% (31/52) of the time, "some expertise" (eg, Wikipedia) 18% of the time, but also magazines and other low quality sources 19% of the time. Using all three methods failed to find relevant information 8% (6/80) of the time, with Siri having the most failed responses (53% of the time). CONCLUSION: Google internet searches and Google Assistant were found to be significantly superior to the Siri digital assistant for smoking cessation information. While expert content was returned over half the time, there is still substantial room for improvement in how these software systems deliver smoking cessation advice. PMID- 29590169 TI - Traction force microscopy of engineered cardiac tissues. AB - Cardiac tissue development and pathology have been shown to depend sensitively on microenvironmental mechanical factors, such as extracellular matrix stiffness, in both in vivo and in vitro systems. We present a novel quantitative approach to assess cardiac structure and function by extending the classical traction force microscopy technique to tissue-level preparations. Using this system, we investigated the relationship between contractile proficiency and metabolism in neonate rat ventricular myocytes (NRVM) cultured on gels with stiffness mimicking soft immature (1 kPa), normal healthy (13 kPa), and stiff diseased (90 kPa) cardiac microenvironments. We found that tissues engineered on the softest gels generated the least amount of stress and had the smallest work output. Conversely, cardiomyocytes in tissues engineered on healthy- and disease mimicking gels generated significantly higher stresses, with the maximal contractile work measured in NRVM engineered on gels of normal stiffness. Interestingly, although tissues on soft gels exhibited poor stress generation and work production, their basal metabolic respiration rate was significantly more elevated than in other groups, suggesting a highly ineffective coupling between energy production and contractile work output. Our novel platform can thus be utilized to quantitatively assess the mechanotransduction pathways that initiate tissue-level structural and functional remodeling in response to substrate stiffness. PMID- 29590170 TI - Histologic subtypes are not associated with the presence of sarcopenia in lung cancer. AB - BACKGROUND: Sarcopenia is prevalent and a known adverse prognostic effector in lung cancer (LCA). However, the relationship between sarcopenia and histology remains uncertain in LCA. METHODS: Consecutive patients with newly diagnosed LCA (n = 778) between June 2012 and February 2015 were retrospectively reviewed to identify factors associated with sarcopenia. Sarcopenia was defined as CT determined L3 muscle index (muscle area at L3/height2) of < 55 cm2/m2 for men and < 39 cm2/m2 for women. RESULTS: Mean patient age was 67.7 +/- 10.8 years, and most (73.1%) were male. The most prevalent histology was adenocarcinoma (44.0%) and 71.6% of patients had stage III or IV disease. The overall prevalence of sarcopenia was 48.2% (60.3% in men, and 15.3% in women). Univariable analysis showed sarcopenia was significantly associated with male gender, age (>= 65 years), smoking status, lower BMI (< 23 kg/m2), advanced stage (III and IV), and high comorbidity score (Charlson index >= 3). Furthermore, the prevalence of sarcopenia was higher in squamous cell carcinoma (54.9%) and small cell LCA (56.4%) than in adenocarcinoma (39.8%). Multivariable analyses showed sarcopenia was independently associated with a male gender (odds ratio [OR], 11.13), elderly (OR, 2.02) and low BMI (OR, 6.28), stage IV (OR, 1.98), and high comorbidity (OR, 1.93). However, no significant association was found between histologic subtypes and sarcopenia. CONCLUSIONS: Sarcopenia was found to be significantly associated with old age, male gender, an advanced stage, comorbidities, and low BMI in LCA. However, histology subtype was not an independent factor for the presence of sarcopenia. PMID- 29590171 TI - PARP1 depletion induces RIG-I-dependent signaling in human cancer cells. AB - DNA Damage Response (DDR) and DNA repair pathways are emerging as potent, ubiquitous suppressors of innate immune signaling in human cells. Here, we show that human cells surviving depletion of the Single Strand Break (SSB) repair protein PARP1 undergo p21-dependent senescence or cell cycle checkpoint activation in the context of activation of innate immune signaling, or viral mimicry. Specifically, we observe induction of a large number of interferon stimulated genes (ISGs) and multiple pattern recognition receptors (PRRs; including RIG-I, MDA-5, MAVS, TLR3 and STING) and increased nuclear IRF3 staining. Mechanistically, depletion of the double-stranded RNA (dsRNA) helicase RIG-I or its downstream effector MAVS specifically rescues ISG induction in PARP1 depleted cells, suggesting that the RIG-I/MAVS pathway is required for sustained ISG expression in this context. Experiments with conditioned media or a neutralizing antibody to the alpha/beta-IFN receptor revealed that persistent ISG expression additionally requires an autocrine/paracrine loop. Finally, loss of PARP1 and radiation-induced DNA damage strongly synergize in the induction of p21 and ISGs. Overall, these findings increase our understanding of how PARP1 may suppress deleterious phenotypes associated to aging, inflammation and cancer in humans.

AB - The temperature-sensitive (ts+) Mycoplasma synoviae vaccine strain MS-H harbors a non-synonymous mutation which results in Glycine to Arginine substitution at position 123 in the highly conserved glycine-rich motif of Obg-fold in the GTP binding protein Obg. In-silico analysis of the wild-type and mutant Obgs of M. synoviae has indicated that this amino acid substitution affects structure of the protein, potentially leading to abrogation of Obg function in vivo. Present study was conducted to develop the first expression vector for M. synoviae and to investigate the potential effect(s) of complementation of MS-H vaccine with the wild-type obg from 86079/7NS, the parent strain of MS-H. An oriC vector, pKS VOTL, harboring the 86079/7NS obg gene, downstream of the variable lipoprotein haemagglutinin (vlhA) gene promoter, also cloned from 86079/7NS, was used to transform MS-H. The plasmid was localised at the chromosomal oriC locus of MS-H without any detectable integration at the chromosomal obg locus. Analysis of the MS-H transformants revealed abundant obg transcripts as well as Obg protein, when compared to the MS-H transformed with a similar vector, pMAS-LoriC, lacking obg coding sequence. The MS-H transformants complemented with wild-type Obg maintained their original temperature-sensitivity phenotype (consistent with MS-H vaccine) but, when compared to the MS-H transformed with pMAS-LoriC, had significantly higher (p < 0.05) growth rate and viability at the permissive (33 degrees C) and non-permissive temperature (39.5 degrees C), respectively. Analysis of Obg expression in MS-H and its wild-type parent strain revealed comparatively lower levels of Obg in MS-H. These results indicate that not only the mutation in Obg, but also the level of Obg expression, can confer functional abnormalities in the bacterial host. Furthermore, with the construction of first expression vector for M. synoviae, this study has set foundation for the development of recombinant vaccine(s) based on MS-H. PMID- 29590173 TI - Soluble klotho as a marker of renal fibrosis and podocyte injuries in human kidneys. AB - Klotho deficiency is relevant to renal fibrosis and podocyte injury in vivo and in vitro. We examined whether histological findings of renal biopsy specimens were associated with the levels of soluble klotho in humans. We investigated renal biopsy specimens of 67 patients and detailed microscopic findings were reviewed. Soluble serum/urinary klotho and urinary angiotensinogen were assessed by enzyme-linked immunosorbent assays, and tissue klotho expression was assessed by immunohistochemical staining. The median age of the study participants was 35.6 years. High serum klotho levels (>=14 pg/mL) were associated with decreased odds ratios (ORs) of interstitial fibrosis (OR = 0.019, P = 0.003) and segmental sclerosis (OR = 0.190, P = 0.022) in multivariable logistic regression analysis. Patients with a lower urinary klotho-to-creatinine ratio (UKCR) were significantly more likely to have diffuse foot process effacement (OR = 0.450, P = 0.010). The area under the receiver-operating characteristic curve (AUC) of serum klotho for predicting interstitial fibrosis was 0.920 (95% CI, 0.844 0.996), and the best cut-off value of serum klotho was 138.1 pg/mL. The AUC of UKCR for predicting diffuse foot process effacement was 0.754 (95% CI, 0.636 0.872), and the best cut-off value of UKCR was 96.7 pg/mgCr. Urinary angiotensinogen-to-creatinine ratio was not associated with serum klotho, UKCR, or any pathological finding. Our data suggested that soluble serum and urinary klotho levels represent a potential biomarker to predict renal fibrosis and podocyte injury in humans. PMID- 29590174 TI - Extending the paleontology-biogeography reciprocity with SDMs: Exploring models and data in reducing fossil taxonomic uncertainty. AB - Historically, studies aimed at prospecting and analyzing paleontological and neontological data to investigate species distribution have developed separately. Research at the interface between paleontology and biogeography has shown a unidirectional bias, mostly focusing on how paleontological information can aid biogeography to understand species distribution through time. However, the modern suit of techniques of ecological biogeography, particularly species distribution models (SDM), can be instrumental for paleontologists as well, improving the biogeography-paleontology interchange. In this study, we explore how to use paleoclimatic data and SDMs to support paleontological investigation regarding reduction of taxonomic uncertainty. Employing current data from two neotropical species (Lagostomus maximus and Myocastor coipus), we implemented SDMs and performed model validation comparing hindcasts with dated fossil occurrences (~14k and ~20k years back present, respectively). Finally, we employed the hindcasting process for two South American fossil records of a misidentified species of caiman (Caiman sp.) to show that C. latirostris is the most likely species identity of these fossils (among four candidate species: C. latirostris, C. yacare, C. crocodilus, and Melanosuchus niger). Possible limitations of the approach are discussed. With this strategy, we have shown that current developments in biogeography research can favour paleontology, extending the (biased) current interchange between these two scientific disciplines. PMID- 29590175 TI - Diet and hygiene practices influence morbidity in schoolchildren living in Schistosomiasis endemic areas along Lake Victoria in Kenya and Tanzania-A cross sectional study. AB - BACKGROUND: Since 2011, cohorts of schoolchildren in regions bordering Lake Victoria in Kenya and Tanzania have been investigated for morbidity caused by Schistosoma mansoni infection. Despite being neighbouring countries with similar lifestyles and ecological environments, Tanzanian schoolchildren had lower S. mansoni prevalence and intensity and they were taller and heavier, fewer were wasted and anaemic, and more were physical fit compared to their Kenyan peers. The aim of the present study was to evaluate whether diet and school-related markers of socioeconomic status (SES) could explain differences in morbidity beyond the effect of infection levels. METHODS AND PRINCIPAL FINDINGS: Parasitological and morbidity data from surveys in 2013-2014 were compared with information on diet and school-related markers of SES collected in 2015 using questionnaires. A total of 490 schoolchildren (163 Kenyans and 327 Tanzanians) aged 9-11 years provided data. A higher proportion of Tanzanian pupils (69.4%, 95% CI: 64.3-74.5) knew where to wash hands after toilet visits compared to Kenyan pupils (48.5%, 95% CI: 40.9-56.1; P<0.0005). Similar proportions of children in the two countries ate breakfast, lunch and dinner, but the content of the meals differed. At all three meals, a higher proportion (95% CI) of Tanzanian pupils consumed animal proteins (mostly fish proteins) compared to their Kenyan peers (35.0% (28.3-41.7) vs. 0%; P<0.0005 at breakfast; 69.0% (63.9-74.1) vs. 43.6% (35.8-51.4); P<0.0005 at lunch; and 67.2% (62.1-72.3) vs. 53.4% (45.8 61.0); P = 0.003 at dinner). Multivariable analyses investigating risk factors for important morbidity markers among individuals revealed that after controlling for schistosome and malaria infections, eating animal proteins (fish) and knowing where to wash hands after toilet visits were significant predictors for both haemoglobin levels and physical fitness (measured as VO2 max). CONCLUSIONS: These results suggest that the differences in morbidity may be affected by factors other than S. mansoni infection alone. Diet and hygiene practice differences were associated with health status of schoolchildren along Lake Victoria in Kenya and Tanzania. TRIAL REGISTRATION: Trials Registration numbers: ISRCT 16755535 (Kenya), ISRCT 95819193 (Tanzania). PMID- 29590176 TI - Differential models of twin correlations in skew for body-mass index (BMI). AB - BACKGROUND: Body Mass Index (BMI), like most human phenotypes, is substantially heritable. However, BMI is not normally distributed; the skew appears to be structural, and increases as a function of age. Moreover, twin correlations for BMI commonly violate the assumptions of the most common variety of the classical twin model, with the MZ twin correlation greater than twice the DZ correlation. This study aimed to decompose twin correlations for BMI using more general skew-t distributions. METHODS: Same sex MZ and DZ twin pairs (N = 7,086) from the community-based Washington State Twin Registry were included. We used latent profile analysis (LPA) to decompose twin correlations for BMI into multiple mixture distributions. LPA was performed using the default normal mixture distribution and the skew-t mixture distribution. Similar analyses were performed for height as a comparison. Our analyses are then replicated in an independent dataset. RESULTS: A two-class solution under the skew-t mixture distribution fits the BMI distribution for both genders. The first class consists of a relatively normally distributed, highly heritable BMI with a mean in the normal range. The second class is a positively skewed BMI in the overweight and obese range, with lower twin correlations. In contrast, height is normally distributed, highly heritable, and is well-fit by a single latent class. Results in the replication dataset were highly similar. CONCLUSIONS: Our findings suggest that two distinct processes underlie the skew of the BMI distribution. The contrast between height and weight is in accord with subjective psychological experience: both are under obvious genetic influence, but BMI is also subject to behavioral control, whereas height is not. PMID- 29590177 TI - Emergence of Orientia tsutsugamushi as an important cause of Acute Encephalitis Syndrome in India. AB - BACKGROUND: Acute Encephalitis Syndrome (AES) is a major seasonal public health problem in Bihar, India. Despite efforts of the Bihar health department and the Government of India, burden and mortality of AES cases have not decreased, and definitive etiologies for the illness have yet to be identified. OBJECTIVES: The present study was undertaken to study the specific etiology of AES in Bihar. METHODS: Cerebrospinal fluid and/or serum samples from AES patients were collected and tested for various pathogens, including viruses and bacteria by ELISA and/or Real Time PCR. FINDINGS: Of 540 enrolled patients, 33.3% (180) tested positive for at least one pathogen of which 23.3% were co-positive for more than one pathogen. Most samples were positive for scrub typhus IgM or PCR (25%), followed by IgM positivity for JEV (8.1%), WNV (6.8%), DV (6.1%), and ChikV (4.5%).M. tuberculosis and S. pneumoniae each was detected in ~ 1% cases. H. influenzae, adenovirus, Herpes Simplex Virus -1, enterovirus, and measles virus, each was detected occasionally. The presence of Scrub typhus was confirmed by PCR and sequencing. Bihar strains resembled Gilliam-like strains from Thailand, Combodia and Vietnam. CONCLUSION: The highlights of this pilot AES study were detection of an infectious etiology in one third of the AES cases, multiple etiologies, and emergence of O. tsutsugamushi infection as an important causative agent of AES in India. PMID- 29590178 TI - Recombinant Zika virus envelope protein elicited protective immunity against Zika virus in immunocompetent mice. AB - Zika virus (ZIKV) has caused great public concerns due to its recent large outbreaks and a close association with microcephaly in fetus and Guillain-Barre syndrome in adults. Rapid development of vaccines against ZIKV is a public health priority. To this end, we have constructed and purified recombinant ZIKV envelope protein using both prokaryotic and eukaryotic expression systems, and then tested their immunogenicity and protective efficacy in immune competent mice. Both protein immunogens elicited humoral and cellular immune responses, and protected immune competent mice from ZIKV challenge in vivo. These products could be further evaluated either as stand-alone vaccine candidate, or used in a prime-and boost regimen with other forms of ZIKV vaccine. PMID- 29590179 TI - Influence of fast advective flows on pattern formation of Dictyostelium discoideum. AB - We report experimental and numerical results on pattern formation of self organizing Dictyostelium discoideum cells in a microfluidic setup under a constant buffer flow. The external flow advects the signaling molecule cyclic adenosine monophosphate (cAMP) downstream, while the chemotactic cells attached to the solid substrate are not transported with the flow. At high flow velocities, elongated cAMP waves are formed that cover the whole length of the channel and propagate both parallel and perpendicular to the flow direction. While the wave period and transverse propagation velocity are constant, parallel wave velocity and the wave width increase linearly with the imposed flow. We also observe that the acquired wave shape is highly dependent on the wave generation site and the strength of the imposed flow. We compared the wave shape and velocity with numerical simulations performed using a reaction-diffusion model and found excellent agreement. These results are expected to play an important role in understanding the process of pattern formation and aggregation of D. discoideum that may experience fluid flows in its natural habitat. PMID- 29590180 TI - Pre-treatment tumour perfusion parameters and initial RECIST response do not predict long-term survival outcomes for patients with head and neck squamous cell carcinoma treated with induction chemotherapy. AB - OBJECTIVES: Previously, we showed that pre-treatment tumour plasma perfusion (Fp) predicts RECIST response to induction chemotherapy (ICT) in locoregionally advanced head and neck squamous cell carcinoma (HNSCC). The aim here was to determine whether the pre-treatment tumour Fp estimate, changes in tumour Fp or RECIST response post 2 cycles of ICT were prognostic for long-term survival outcomes. METHODS: A prospective study enrolled patients with high stage HNSCC treated with docetaxel (T), cisplatin (P) and 5-fluorouracil (F) (ICT) followed by synchronous cisplatin and intensity modulated radiotherapy. Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) before and after two cycles of ICT was used to measure Fp and RECIST response. RESULTS: Forty-two patients were recruited and 37 underwent two scans. The median follow-up was 36 (range 23-49) months. Pre-treatment tumour Fp (stratified by median) was not prognostic for overall survival (p = 0.42), disease specific survival (p = 0.20) and locoregional control (p = 0.64). Neither change in tumour Fp nor RECIST response post two cycles of ICT was prognostic for any outcome (p>0.21). CONCLUSION: DCE MRI parameters do not predict long-term survival outcomes following ICT and RECIST response to ICT may not be an appropriate endpoint to determine early efficacy of a treatment in HNSCC patients. PMID- 29590181 TI - Modulation of inhibitory control by prefrontal anodal tDCS: A crossover double blind sham-controlled fMRI study. AB - Prefrontal anodal transcranial direct current stimulation (tDCS) has been proposed as a potential approach to improve inhibitory control performance. The functional consequences of tDCS during inhibition tasks remain, however, largely unresolved. We addressed this question by analyzing functional magnetic resonance imaging (fMRI) recorded while participants completed a Go/NoGo task after right lateralized prefrontal anodal tDCS with a crossover, sham-controlled, double blind experimental design. We replicated previous evidence for an absence of offline effect of anodal stimulation on Go/NoGo performance. The fMRI results revealed a larger increase in right ventrolateral prefrontal activity for Go than NoGo trials in the anodal than sham condition. This pattern suggests that tDCS induced increases in cortical excitability have larger effects on fMRI activity in regions with a lower task-related engagement. This was the case for the right prefrontal cortex in the Go condition in our task because while reactive inhibition was not engaged during execution trials, the unpredictability of the demand for inhibitory control still incited an engagement of proactive inhibition. Exploratory analyses further revealed that right prefrontal stimulation interacted with task-related functional demands in the supplementary motor area and the thalamus. Our collective results emphasize the dependency of offline tDCS functional effects on the task-related engagement of the stimulated areas and suggest that this factor might partly account for the discrepancies in the functional effects of tDCS observed in previous studies. PMID- 29590182 TI - Clinical endpoints in the controlled human challenge model for Shigella: A call for standardization and the development of a disease severity score. AB - BACKGROUND: Since 1946 the controlled human infection model (CHIM) for Shigella has been used to improve understanding of disease pathogenesis, describe clinical and immunologic responses to infection and as a tool for vaccine development. As the frequency and intent for use in vaccine comparisons increases, standardization of the primary endpoint definition is necessary. METHODS: Subject level data were obtained from previously conducted experimental Shigella CHIM studies. Signs and symptoms severity were categorized consistently across all studies. Sign and symptom correlations were estimated and univariate models were utilized to describe the association between stool output and other Shigella attributable signs and symptoms. Multiple correspondence and hierarchical clustering analyses were performed to describe the co-occurrence of signs and symptoms. A disease score is proposed based on the co-occurrence of these events. RESULTS: Data were obtained on 54 subjects receiving 800 to 2000 colony forming units (cfu) of S. flexneri. The median maximum 24 hour stool output was 514 ml (IQR: 300, 998 ml) with a median frequency of 6 (IQR: 4, 9). Subjects reported abdominal pain or cramps (81.5%), headache (66.7%) and anorexia (64.8%), 50.0% had a fever and 27.8% had gross blood in multiple loose stools. Multiple correspondence analyses highlighted co-occurrence of symptoms based on severity. A 3-parameter disease severity score predicted shigellosis endpoints and better differentiated disease spectrum. CONCLUSION: Dichotomous endpoints for Shigella CHIM fail to fully account for disease variability. An ordinal disease score characterizing the breadth of disease severity may enable a better characterization of shigellosis and can decrease sample size requirements. Furthermore, the disease severity score may be a useful tool for portfolio management by enabling prioritization across vaccine candidates with comparable efficacy estimates using dichotomous endpoints. PMID- 29590183 TI - High health literacy is associated with less obesity and lower Framingham risk score: Sub-study of the VGH-HEALTHCARE trial. AB - BACKGROUNDS: Lower health literacy (HL) is associated with several cardiovascular disease (CVD) risk factors such as diabetes, hypertension, and metabolic syndrome (MS). The aim of our study was to investigate the association between HL and the Framingham 10-year risk score of CVD. METHODS: From 2015-2016, 1010 subjects aged 23 to 88 years receiving health check-up in Taipei Veterans General Hospital had complete clinical evaluations and laboratory examinations. Fatty liver was diagnosed by ultrasonography. The short form questionnaire adapted from the Mandarin Health Literacy Scale was used to assess HL. The Framingham risk score was calculated by patient characteristics. RESULTS: Subjects with higher BMIs were associated with lower HL scores. The proportion of subjects with MS was higher in the lower health literacy score group (<= 9) at 28.8%; further analysis found that lower HL was significantly associated with MS in women but not in men. The Spearman's rho demonstrated that the HL score was significantly associated with the BMI-based (rho = -0.11; P < 0.001) or lipid-based (rho = -0.09; P < 0.004) Framingham risk score. CONCLUSIONS: Higher HL scores were associated with less CVD risk such as lower BMIs, less MS in women, and less fatty liver disease. Furthermore, HL had an inverse association with the Framingham risk score as expected. Therefore, HL in patients with CVD risk should be improved and considered as an important issue in terms of CVD reduction. PMID- 29590184 TI - Gene cloning of a neutral ceramidase from the sphingolipid metabolic pathway based on transcriptome analysis of Amorphophallus muelleri. AB - Amorphophallus is a perennial herbaceous plant species mainly distributed in the tropics or subtropics of Asia and Africa. It has been used as a traditional medicine for a long time and now is utilized for the pharmaceutical, chemical and agriculture industries as a valued economic crop. Recently, Amorphophallus has attracted tremendous interest because of its high ceramide content. However, the breeding and genome studies are severely limited by the arduous whole genome sequencing of Amorphophallus. In this study, the transcriptome data of A. muelleri was obtained by utilizing the high-throughput Illumina sequencing platform. Based on this information, the majority of the significant genes involved in the proposed sphingolipid metabolic pathway were identified. Then, the full-length neutral ceramidase cDNA was obtained with the help of its candidate transcripts, which were acquired from the transcriptome data. Furthermore, we demonstrated that this neutral ceramidase was a real ceramidase by eukaryotic expression in the yeast double knockout mutant Deltaypc1 Deltaydc1, which lacks the ceramidases-dihydroCDase (YDC1p), phytoCDase (YPC1p). In addition, the biochemical characterization of purified A. muelleri ceramidase (AmCDase) exhibited classical Michaelis-Menten kinetics with an optimal activity ranging from pH 6.5 to 8.0. Based on our knowledge, this study is the first to report the related information of the neutral ceramidase in Amorphophallus. All datasets can provide significant information for related studies, such as gene expression, genetic improvement and application on breeding in Amorphophallus. PMID- 29590185 TI - New insights into the genome repetitive fraction of the Antarctic bivalve Adamussium colbecki. AB - Repetitive DNA represents the major component of the genome in both plant and animal species. It includes transposable elements (TEs), which are dispersed throughout the genome, and satellite DNAs (satDNAs), which are tandemly organized in long arrays. The study of the structure and organization of repetitive DNA contributes to our understanding of genome architecture and the mechanisms leading to its evolution. Molluscs represent one of the largest groups of invertebrates and include organisms with a wide variety of morphologies and lifestyles. To increase our knowledge of bivalves at the genome level, we analysed the Antarctic scallop Adamussium colbecki. The screening of the genomic library evidenced the presence of two novel satDNA elements and the CvA transposon. The interspecific investigation performed in this study demonstrated that one of the two satDNAs isolated in A. colbecki is widespread in polar molluscan species, indicating a possible link between repetitive DNA and abiotic factors. Moreover, the transcriptional activity of CvA and its presence in long diverged bivalves suggests a possible role for this ancient element in shaping the genome architecture of this clade. PMID- 29590186 TI - JMJD1A, H3K9me1, H3K9me2 and ADM expression as prognostic markers in oral and oropharyngeal squamous cell carcinoma. AB - AIMS: Jumonji Domain-Containing 1A (JMJD1A) protein promotes demethylation of histones, especially at lysin-9 of di-methylated histone H3 (H3K9me2) or mono methylated (H3K9me1). Increased levels of H3 histone methylation at lysin-9 (H3K9) is related to tumor suppressor gene silencing. JMJD1A gene target Adrenomeduline (ADM) has shown to promote cell growth and tumorigenesis. JMJD1A and ADM expression, as well as H3K9 methylation level have been related with development risk and prognosis of several tumor types. METHODS AND RESULTS: We aimed to evaluate JMJD1A, ADM, H3K9me1 and H3K9me2expression in paraffin-embedded tissue microarrays from 84 oral and oropharyngeal squamous cell carcinoma samples through immunohistochemistry analysis. Our results showed that nuclear JMJD1A expression was related to lymph node metastasis risk. In addition, JMJD1A cytoplasmic expression was an independent risk marker for advanced tumor stages. H3K9me1 cytoplasmic expression was associated with reduced disease-specific death risk. Furthermore, high H3K9me2 nuclear expression was associated with worse specific-disease and disease-free survival. Finally, high ADM cytoplasmic expression was an independent marker of lymph node metastasis risk. CONCLUSION: JMJD1A, H3K9me1/2 and ADM expression may be predictor markers of progression and prognosis in oral and oropharynx cancer patients, as well as putative therapeutic targets. PMID- 29590187 TI - Is endotracheal intubation a non-beneficial treatment in patients with respiratory failure due to paraquat poisoning? AB - INTRODUCTION: Paraquat poisoning can result in dysfunction of multiple organs, and pulmonary fibrosis with respiratory failure is the major cause of mortality. For terminally ill patients, some life-prolonging treatments can be non beneficial treatments (NBT). The objective of this study was to determine if intubation is a NBT for patients with respiratory failure due to paraquat poisoning. METHODS: The study included 68 patients with respiratory failure due to paraquat poisoning. Patients were hospitalized at MacKay Memorial Hospital, Taitung Branch, Taiwan, between 2005 to April 2016. Composite outcomes of intra hospital mortality, the rate of do-not-resuscitate (DNR) orders, prescribed medications, length of stay, and medical costs were recorded and compared between the do-not-intubate (DNI) group and endotracheal intubation (EI) group. RESULTS: Intra-hospital mortality rate for the entire population was 100%. There were significantly more patients with DNR orders in the DNI group (P = 0.007). There were no differences in the length of hospital stay. However, patients in DNI group had significantly less vasopressor use and more morphine use, shorter time in the intensive care unit, and fewer medical costs. CONCLUSION: The procedure of intubation in patients with respiratory failure due to paraquat poisoning can be considered inappropriate life-prolonging treatment. PMID- 29590188 TI - Overview of systematic reviews assessing the evidence for shorter versus longer duration antibiotic treatment for bacterial infections in secondary care. AB - Our objective was to assess the clinical effectiveness of shorter versus longer duration antibiotics for treatment of bacterial infections in adults and children in secondary care settings, using the evidence from published systematic reviews. We conducted electronic searches in MEDLINE, Embase, Cochrane, and Cinahl. Our primary outcome was clinical resolution. The quality of included reviews was assessed using the AMSTAR criteria, and the quality of the evidence was rated using the GRADE criteria. We included 6 systematic reviews (n = 3,162). Four reviews were rated high quality, and two of moderate quality. In adults, there was no difference between shorter versus longer duration in clinical resolution rates for peritonitis (RR 1.03, 95% CI 0.98 to 1.09, I2 = 0%), ventilator associated pneumonia (RR 0.93; 95% CI 0.81 to 1.08, I2 = 24%), or acute pyelonephritis and septic UTI (clinical failure: RR 1.00, 95% CI 0.46 to 2.18). The quality of the evidence was very low to moderate. In children, there was no difference in clinical resolution rates for pneumonia (RR 0.98, 95% CI 0.91 to 1.04, I2 = 48%), pyelonephritis (RR 0.95, 95% CI 0.88 to 1.04) and confirmed bacterial meningitis (RR 1.02, 95% CI 0.93 to 1.11, I2 = 0%). The quality of the evidence was low to moderate. In conclusion, there is currently a limited body of evidence to clearly assess the clinical benefits of shorter versus longer duration antibiotics in secondary care. High quality trials assessing strategies to shorten antibiotic treatment duration for bacterial infections in secondary care settings should now be a priority. PMID- 29590190 TI - MINErosion 3: Using measurements on a tilting flume-rainfall simulator facility to predict erosion rates from post-mining landscapes in Central Queensland, Australia. AB - Open-cut coal mining in Queensland results in the formation of extensive saline overburden spoil-piles with steep slopes at the angle of repose (approximately 75% or 37o). These spoil-piles are generally found in multiple rows, several kilometers in length and heights of up to 50 or 60 m above the original landscape. They are highly dispersive and erodible. Legislation demands that these spoil piles be rehabilitated to minimize on-site and off-site discharges of sediment and salt into the surrounding environment. To achieve this, the steep slopes must be reduced, stabilized against erosion, covered with topsoil and re vegetated. Key design criteria (slope gradient, slope length and vegetation cover) are required for the construction of post-mining landscapes that will result in acceptable erosion rates. A novel user-friendly hillslope computer model MINErosion 3.4 was developed that can accurately predict potential erosion rates from field scale hillslopes using parameters measured with a 3m laboratory tilting flume-rainfall simulator or using routinely measured soil physical and chemical properties. This model links MINErosion 2 with a novel consolidation and above ground vegetation cover factors, to the RUSLE and MUSLE equations to predict the mean annual and storm event erosion rates. The RUSLE-based prediction of the mean annual erosion rates allow minesites to derive the key design criteria of slope length, slope gradient and vegetation cover that would lead to acceptable erosion rates. The MUSLE-based prediction of storm event erosion rates will be useful as input into risk analysis of potential damage from erosion. MINErosion 3.4 was validated against erosion measured on 20 m field erosion plots established on post-mining landscapes at the Oakey Creek and Curragh coalmines, as well as on 120 and 70 m erosion plots on postmining landscapes at Kidston Gold Mine. PMID- 29590189 TI - Versatile approach for functional analysis of human proteins and efficient stable cell line generation using FLP-mediated recombination system. AB - Deciphering a function of a given protein requires investigating various biological aspects. Usually, the protein of interest is expressed with a fusion tag that aids or allows subsequent analyses. Additionally, downregulation or inactivation of the studied gene enables functional studies. Development of the CRISPR/Cas9 methodology opened many possibilities but in many cases it is restricted to non-essential genes. Recombinase-dependent gene integration methods, like the Flp-In system, are very good alternatives. The system is widely used in different research areas, which calls for the existence of compatible vectors and efficient protocols that ensure straightforward DNA cloning and generation of stable cell lines. We have created and validated a robust series of 52 vectors for streamlined generation of stable mammalian cell lines using the FLP recombinase-based methodology. Using the sequence-independent DNA cloning method all constructs for a given coding-sequence can be made with just three universal PCR primers. Our collection allows tetracycline-inducible expression of proteins with various tags suitable for protein localization, FRET, bimolecular fluorescence complementation (BiFC), protein dynamics studies (FRAP), co immunoprecipitation, the RNA tethering assay and cell sorting. Some of the vectors contain a bidirectional promoter for concomitant expression of miRNA and mRNA, so that a gene can be silenced and its product replaced by a mutated miRNA insensitive version. Our toolkit and protocols have allowed us to create more than 500 constructs with ease. We demonstrate the efficacy of our vectors by creating stable cell lines with various tagged proteins (numatrin, fibrillarin, coilin, centrin, THOC5, PCNA). We have analysed transgene expression over time to provide a guideline for future experiments and compared the effectiveness of commonly used inducers for tetracycline-responsive promoters. As proof of concept we examined the role of the exoribonuclease XRN2 in transcription termination by RNAseq. PMID- 29590191 TI - Gut-bone axis response to dietary replacement of soybean meal with raw low-tannin faba bean seeds in broiler chickens. AB - It seems that faba bean (FB) seeds could be a good protein-energy component in animal feed, but the presence of anti-nutritional substances limits their use as a substitute of soybean meal. The aim of the study was to examine the influence of different concentrations of raw, low-tannin, FB seeds on the gut-bone axis in Ross 308 broilers. One-day old chickens were randomly subjected to one of the 3 dietary treatments: the control group was fed standard diet based on soybean meal and without FB seeds, and two groups were fed 8%/15% and 16%/22% of raw low tannin FB seeds in the starter and grower, respectively. On the 35th day, hematological and serum biochemical analyses as well histomorphometry of the small intestine and liver tissue and bone mechanical tests were performed. The diet type had no effect on the body weight gain and feed conversion ratio. However, the basal intestinal structures were significantly reduced in birds fed the lower concentration of FB. The enlargement of nerve plexuses was dependent on the concentration used in the diet and, additionally, on the kind of plexus and location in the intestinal tract. The liver was characterized by an increase in non-hepatocytes. There was no influence of the low-tannin FB seeds on most of the analyzed serum parameters in the 35-day-old broiler chickens, except the decreased concentration of total cholesterol and Ca in both experimental groups, triglycerides in group I, and P and uric acid in group II. Furthermore, the increasing concentration of the dietary low-tannin FB did not influence the activities of AspAT (except the group fed the higher amount of FB), ALAT, and LDH. The broiler chickens had no visible leg lesions and no problem in the locomotor function, but the tibiae were lighter mainly in birds fed the higher concentration of FB seeds. Geometric analysis revealed reduction of the cross section area and wall thickness, indicating a decline in the bone midshaft, which influenced the densitometric parameters and the results of mechanical tests. In conclusion, the dietary inclusion of raw low-tannin FB seeds had no negative effects on broiler growth, but disturbed the intestine structure and tibia characteristics. Therefore, all these negative effects necessitate additional examinations before inclusion of raw low-tannin FB seed into poultry diet. PMID- 29590192 TI - Landscape connectivity for bobcat (Lynx rufus) and lynx (Lynx canadensis) in the Northeastern United States. AB - Landscape connectivity is integral to the persistence of metapopulations of wide ranging carnivores and other terrestrial species. The objectives of this research were to investigate the landscape characteristics essential to use of areas by lynx and bobcats in northern New England, map a habitat availability model for each species, and explore connectivity across areas of the region likely to experience future development pressure. A Mahalanobis distance analysis was conducted on location data collected between 2005 and 2010 from 16 bobcats in western Vermont and 31 lynx in northern Maine to determine which variables were most consistent across all locations for each species using three scales based on average 1) local (15 minute) movement, 2) linear distance between daily locations, and 3) female home range size. The bobcat model providing the widest separation between used locations and random study area locations suggests that they cue into landscape features such as edge, availability of cover, and development density at different scales. The lynx model with the widest separation between random and used locations contained five variables including natural habitat, cover, and elevation-all at different scales. Shrub scrub habitat-where lynx's preferred prey is most abundant-was represented at the daily distance moved scale. Cross validation indicated that outliers had little effect on models for either species. A habitat suitability value was calculated for each 30 m2 pixel across Vermont, New Hampshire, and Maine for each species and used to map connectivity between conserved lands within selected areas across the region. Projections of future landscape change illustrated potential impacts of anthropogenic development on areas lynx and bobcat may use, and indicated where connectivity for bobcats and lynx may be lost. These projections provided a guide for conservation of landscape permeability for lynx, bobcat, and species relying on similar habitats in the region. PMID- 29590193 TI - Automated C. elegans embryo alignments reveal brain neuropil position invariance despite lax cell body placement. AB - The Caenorhabditis elegans cell lineage is nearly invariant. Whether this stereotyped cell-division pattern promotes reproducibility in cell shapes/positions is not generally known, as manual spatiotemporal cell shape/position alignments are labor-intensive, and fully-automated methods are not described. Here, we report automated algorithms for spatiotemporal alignments of C. elegans embryos from pre-morphogenesis to motor-activity initiation. We use sparsely-labeled green-fluorescent nuclei and a pan-nuclear red-fluorescent reporter to register consecutive imaging time points and compare embryos. Using our method, we monitor early assembly of the nerve-ring (NR) brain neuropil. While NR pioneer neurons exhibit reproducible growth kinetics and axon positions, cell-body placements are variable. Thus, pioneer-neuron axon locations, but not cell-body positions, are under selection. We also show that anterior NR displacement in cam-1/ROR Wnt-receptor mutants is not an early NR assembly defect. Our results demonstrate the utility of automated spatiotemporal alignments of C. elegans embryos, and uncover key principles guiding nervous system development in this animal. PMID- 29590194 TI - Highly-sensitive detection of Salmonella typhi in clinical blood samples by magnetic nanoparticle-based enrichment and in-situ measurement of isothermal amplification of nucleic acids. AB - Enteric fever continues to be a major cause of mortality and morbidity globally, particularly in poor resource settings. Lack of rapid diagnostic assays is a major driving factor for the empirical treatment of enteric fever. In this work, a rapid and sensitive method 'Miod' 'has been developed. Miod includes a magnetic nanoparticle-based enrichment of target bacterial cells, followed by cell lysis and loop-mediated isothermal amplification (LAMP) of nucleic acids for signal augmentation along with concurrent measurement of signal via an in-situ optical detection system. To identify positive/negative enteric fever infections in clinical blood samples, the samples were processed using Miod at time = 0 hours and time = 4 hours post-incubation in blood culture media. Primers specific for the STY2879 gene were used to amplify the nucleic acids isolated from S. typhi cells. A limit of detection of 5 CFU/mL was achieved. No cross-reactivity of the primers were observed against 106 CFU/mL of common pathogenic bacterial species found in blood such as E. coli, P. aeruginosa, S. aureus, A. baumanni, E. faecalis, S. Paratyphi A and K. pneumonia. Miod was tested on 28 human clinical blood samples. The detection of both pre-and post-four-hours incubation confirmed the presence of viable S. typhi cells and allowed clinical correlation of infection. The positive and negative samples were successfully detected in less than 6 hours with 100% sensitivity and specificity. PMID- 29590195 TI - The neurochemistry and morphology of functionally identified corneal polymodal nociceptors and cold thermoreceptors. AB - It is generally believed that the unencapsulated sensory nerve terminals of modality specific C- and Adelta-neurons lack structural specialization. Here we determined the morphology of functionally defined polymodal receptors and cold thermoreceptors in the guinea pig corneal epithelium. Polymodal receptors and cold thermoreceptors were identified by extracellular recording at the surface of the corneal epithelium. After marking the recording sites, corneas were processed to reveal immunoreactivity for the transient receptor potential channels TRPV1 (transient receptor potential cation channel, subfamily V, member 1) or TPRM8 (transient receptor potential cation channel subfamily M member 8). Polymodal receptor nerve terminals (n = 6) were TRPV1-immunoreactive and derived from an axon that ascended from the sub-basal plexus to the squamous cell layer where it branched into fibers that ran parallel to the corneal surface and terminated with small bulbar endings (ramifying endings). Cold thermoreceptor nerve terminals were TRPM8-immunoreactive (n = 6) and originated from an axon that branched as it ascended through the wing cell and squamous cell layers and terminated with large bulbar endings (complex endings). These findings indicate that modality specific corneal sensory neurons with unencapsulated nerve endings have distinct nerve terminal morphologies that are likely to relate to their function. PMID- 29590196 TI - Asymptomatic norovirus infection associated with swimming at a tropical beach: A prospective cohort study. AB - BACKGROUND: Swimming in fecally-contaminated waterbodies can result in gastrointestinal infections. However, the pathogenic microorganisms responsible are not well understood because sporadic cases of illness are not reported completely, exposure information is often not collected, and epidemiology studies rely on self-reported symptoms. Noroviruses are considered a likely cause because they are found in high densities in sewage, resistant to wastewater treatment and survive in the environment. In this study, saliva samples were collected from subjects at a beach in Puerto Rico and tested for evidence of norovirus-specific IgG responses as an indicator of incident norovirus infection. METHODS: Saliva samples were collected from 1298 participants using an oral swab. Samples were collected on the day of the beach visit (S1); after 10-12 days (S2); and after three weeks (S3). Saliva was tested for IgG responses to GI.1 and GII.4 noroviruses using a microsphere based multiplex salivary immunoassay. Immunoconversion was defined as a four-fold increase in median fluorescence intensity (MFI) from S1 to S2 with the S3 sample at least three times above the S1 MFI. RESULTS: Thirty-four subjects (2.6%) immunoconverted to GI.1 or GII.4 norovirus. Swimmers who immersed their head in water had a higher rate of immunoconversion (3.4%), compared to either non-swimmers (0.0%, p = 0.003) or waders and non-swimmers combined (0.4%, Odds Ratio: 5.07, 95% Confidence Interval:1.48-17.00). Immunoconversion was not associated with gastrointestinal symptoms. CONCLUSIONS: This is the first study to demonstrate an association between swimming at a beach impacted by fecal contamination and asymptomatic norovirus infection. The findings implicate recreational water as potentially important transmission pathway for norovirus infection. PMID- 29590197 TI - Correlation between coronary artery calcification by non-cardiac CT and Framingham score in young patients. AB - BACKGROUND: Previous studies have established a correlation between coronary artery calcification (CAC) measured by ECG-gated chest computed tomography (CT) and cardiovascular disease. Recent reports which included asymptomatic patients suggest that CAC measured on non-ECG gated CT is similarly associated with cardiovascular risk. This study investigates the correlation between the Framingham Risk Score (FRS) and an incidental finding of CAC on a non-gated chest CT performed for non-cardiac indications in young and seemingly healthy adults. METHODS: A cross-sectional study that included 162 CT scans performed in young patients aged 18-50 years old for non-cardiac indications in our institution was conducted. CAC score (CACS) was calculated using the Agatston method. FRS was calculated and compared to the CACS using three different approaches. The correlations between the CACS and several specific factors (i.e. age, body mass index, smoking, statins, etc.), were also evaluated. RESULTS: Mean age of patients was 36.43 year old and 105 (64.8%) were male. We found a significant positive correlation between the CACS and the FRS in all three approaches (p<0.05). Increased age, smoking and statin use were the only individual factors clearly associated with an increase in CACS (p = 0.002, p = 0.045 and p = 0.009, respectively). CONCLUSION: This is the first report indicating that incidental CACS identified in non-gated MDCT is also associated with cardiovascular risk evaluated by FRS in a young population. Our findings suggest that young asymptomatic individuals with incidental CAC should be seriously evaluated for cardiovascular risk factors despite presumption of belonging to a low cardiovascular risk category. PMID- 29590198 TI - Verrucomicrobia are prevalent in north-temperate freshwater lakes and display class-level preferences between lake habitats. AB - The bacterial phylum Verrucomicrobia was formally described two decades ago and originally believed to be a minor member of many ecosystems; however, it is now recognized as ubiquitous and abundant in both soil and aquatic systems. Nevertheless, knowledge of the drivers of its relative abundance and within phylum habitat preferences remains sparse, especially in lake systems. Here, we documented the distribution of Verrucomicrobia in 12 inland lakes in Southeastern Michigan, a Laurentian Great Lake (Lake Michigan), and a freshwater estuary, which span a gradient in lake sizes, depths, residence times, and trophic states. A wide range of physical and geochemical parameters was covered by sampling seasonally from the surface and bottom of each lake, and by separating samples into particle-associated and free-living fractions. On average, Verrucomicrobia was the 4th most abundant phylum (range 1.7-41.7%). Fraction, season, station, and depth explained up to 70% of the variance in Verrucomicrobia community composition and preference for these habitats was phylogenetically conserved at the class-level. When relative abundance was linearly modeled against environmental data, Verrucomicrobia and non-Verrucomicrobia bacterial community composition correlated to similar quantitative environmental parameters, although there were lake system-dependent differences and > 55% of the variance remained unexplained. A majority of the phylum exhibited preference for the particle associated fraction and two classes (Opitutae and Verrucomicrobiae) were identified to be more abundant during the spring season. This study highlights the high relative abundance of Verrucomicrobia in north temperate lake systems and expands insights into drivers of within-phylum habitat preferences of the Verrucomicrobia. PMID- 29590199 TI - The urine albumin-creatinine ratio is a predictor for incident long-term care in a general population. AB - BACKGROUND: Several types of cardiovascular diseases (CVDs) impair the physical and mental status. The purpose of this study was to assess the predictive ability of several cardiovascular biomarkers for identifying the incidence of disability as future recipients of public long-term care (LTC) service. METHODS: The subjects of this study were community-dwelling elderly individuals >= 65 years of age without a history of CVD (n = 5,755; mean age, 71 years). The endpoint of this study was official certification as a recipient of LTC. The cohort was divided into quartiles (Qs) based on the levels of three CVD biomarkers: the urinary albumin-creatinine ratio (UACR), plasma B-type natriuretic peptide concentration (BNP), and serum high-sensitivity C-reactive protein concentration (hsCRP). A time-dependent Cox proportional hazard model was used to determine the multi-adjusted relative hazard ratios (HRs) for incident LTC among the quartiles of each biomarker. RESULTS: During the follow-up (mean 5.6 years), 710 subjects were authorized as recipients of LTC. The HR was only significantly increased in the higher Qs of UACR (Q3, p < 0.01; Q4, p < 0.001). However, other biomarkers were not significantly associated with the endpoint. The risk predictive performance for the incidence of LTC as evaluated by an essential model (i.e. age and sex-adjusted) was significantly improved by incorporating the UACR (net reclassification improvement = 0.084, p < 0.01; integrated discrimination improvement = 0.0018, p < 0.01). CONCLUSIONS: These results suggest that an increased UACR is useful for predicting physical and cognitive dysfunction in an elderly general population. PMID- 29590200 TI - Retrospective harm benefit analysis of pre-clinical animal research for six treatment interventions. AB - BACKGROUND: The harm benefit analysis (HBA) is the cornerstone of animal research regulation and is considered to be a key ethical safeguard for animals. The HBA involves weighing the anticipated benefits of animal research against its predicted harms to animals but there are doubts about how objective and accountable this process is. OBJECTIVES: i. To explore the harms to animals involved in pre-clinical animal studies and to assess these against the benefits for humans accruing from these studies; ii. To test the feasibility of conducting this type of retrospective HBA. METHODS: Data on harms were systematically extracted from a sample of pre-clinical animal studies whose clinical relevance had already been investigated by comparing systematic reviews of the animal studies with systematic reviews of human studies for the same interventions (antifibrinolytics for haemorrhage, bisphosphonates for osteoporosis, corticosteroids for brain injury, Tirilazad for stroke, antenatal corticosteroids for neonatal respiratory distress and thrombolytics for stroke). Clinical relevance was also explored in terms of current clinical practice. Harms were categorised for severity using an expert panel. The quality of the research and its impact were considered. Bateson's Cube was used to conduct the HBA. RESULTS: The most common assessment of animal harms by the expert panel was 'severe'. Reported use of analgesia was rare and some animals (including most neonates) endured significant procedures with no, or only light, anaesthesia reported. Some animals suffered iatrogenic harms. Many were kept alive for long periods post experimentally but only 1% of studies reported post-operative care. A third of studies reported that some animals died prior to endpoints. All the studies were of poor quality. Having weighed the actual harms to animals against the actual clinical benefits accruing from these studies, and taking into account the quality of the research and its impact, less than 7% of the studies were permissible according to Bateson's Cube: only the moderate bisphosphonate studies appeared to minimise harms to animals whilst being associated with benefit for humans. CONCLUSIONS: This is the first time the accountability of the HBA has been systematically explored across a range of pre-clinical animal studies. The regulatory systems in place when these studies were conducted failed to safeguard animals from severe suffering or to ensure that only beneficial, scientifically rigorous research was conducted. Our findings indicate a pressing need to: i. review regulations, particularly those that permit animals to suffer severe harms; ii. reform the processes of prospectively assessing pre-clinical animal studies to make them fit for purpose; and iii. systematically evaluate the benefits of pre-clinical animal research to permit a more realistic assessment of its likely future benefits. PMID- 29590201 TI - Using mating-type loci to improve taxonomy of the Tuber indicum complex, and discovery of a new species, T. longispinosum. AB - Black truffles that morphologically resemble Tuber indicum have been known to occur in Japan since 1979. Our previous studies showed that there are two phylotypes of these truffles, both of which fell into the T. indicum complex (hereinafter "Tuber sp. 6" and "Tuber sp. 7"). However, their taxonomic treatment is still unclear. In this study, we conducted morphological and phylogenetic analyses for a total of 52 specimens from Japan (16 Tuber sp. 6 and 13 Tuber sp. 7), China (10 T. himalayense and 8 T. indicum), and Taiwan (5 T. formosanum). We compared ascospore ornamentation, size, distribution of asci with average number of spores per ascus, spine size and shape of the Japanese specimens with their allied taxa. For phylogenetic analysis, we sequenced two mating loci (MAT1-1-1 and MAT1-2-1) and three commonly used loci (ITS, beta-tubulin, and TEF1-alpha). Three distinct lineages were recognized by phylogenetic analyses based on the sequences of the two mating-related loci and three independent loci. The Tuber sp. 6 sequences clustered with those of T. himalayense and T. formosanum, and there was no clear difference in morphology among them. Tuber sp. 7 formed a distinct lineage in each phylogram. The specimens tended to have five-spored asci more frequently than other allied species and could be characterized as having ascospore ornamentation with longer spines and narrower spine bases. We therefore described Tuber sp. 7 as a new species (T. longispinosum), and treat Tuber sp. 6 and T. formosanum as synonyms of T. himalayense. PMID- 29590202 TI - Molecularly barcoded Zika virus libraries to probe in vivo evolutionary dynamics. AB - Defining the complex dynamics of Zika virus (ZIKV) infection in pregnancy and during transmission between vertebrate hosts and mosquito vectors is critical for a thorough understanding of viral transmission, pathogenesis, immune evasion, and potential reservoir establishment. Within-host viral diversity in ZIKV infection is low, which makes it difficult to evaluate infection dynamics. To overcome this biological hurdle, we constructed a molecularly barcoded ZIKV. This virus stock consists of a "synthetic swarm" whose members are genetically identical except for a run of eight consecutive degenerate codons, which creates approximately 64,000 theoretical nucleotide combinations that all encode the same amino acids. Deep sequencing this region of the ZIKV genome enables counting of individual barcodes to quantify the number and relative proportions of viral lineages present within a host. Here we used these molecularly barcoded ZIKV variants to study the dynamics of ZIKV infection in pregnant and non-pregnant macaques as well as during mosquito infection/transmission. The barcoded virus had no discernible fitness defects in vivo, and the proportions of individual barcoded virus templates remained stable throughout the duration of acute plasma viremia. ZIKV RNA also was detected in maternal plasma from a pregnant animal infected with barcoded virus for 67 days. The complexity of the virus population declined precipitously 8 days following infection of the dam, consistent with the timing of typical resolution of ZIKV in non-pregnant macaques and remained low for the subsequent duration of viremia. Our approach showed that synthetic swarm viruses can be used to probe the composition of ZIKV populations over time in vivo to understand vertical transmission, persistent reservoirs, bottlenecks, and evolutionary dynamics. PMID- 29590204 TI - Can sign language make you better at hand processing? AB - The languages developed by deaf communities are unique for using visual signs produced by the hand. In the present study, we explored the cognitive effects of employing the hand as articulator. We focused on the arbitrariness of the form meaning relationship-a fundamental feature of natural languages-and asked whether sign languages change the processing of arbitrary non-linguistic stimulus response (S-R) associations involving the hand. This was tested using the Simon effect, which specifically requires such type of associations. Differences between signers and speakers (non-signers) only appeared in the Simon task when hand stimuli were shown. Response-time analyses revealed that the distinctiveness of signers' responses derived from an increased ability to process memory traces of arbitrary S-R pairs related to the hand. These results shed light on the interplay between language and cognition as well as on the effects of sign language acquisition. PMID- 29590203 TI - Reprogramming of the estrogen responsive transcriptome contributes to tamoxifen dependent protection against tumorigenesis in the p53 null mammary epithelial cells. AB - The tumor suppressor gene p53 is frequently mutated in human breast cancer and is a marker for poor prognosis and resistance to chemotherapy. Transplantation of p53 null mouse mammary epithelium into syngeneic wild-type mice leads to normal mammary gland development followed by spontaneous mammary tumors that recapitulate many of the phenotypic, molecular and genetic features of human breast cancer. Transient exposure of p53 null mice to the anti-estrogen, tamoxifen leads to sustained and robust protection against tumor development. However the mechanism underlying this anti-tumor activity remains poorly understood. Here we demonstrate that transient exposure to tamoxifen leads to a reduction in mammary ductal side-branching and epithelial cell proliferation after tamoxifen withdrawal. Global gene expression analysis showed that transient tamoxifen exposure leads to persistent changes in the expression of a subset of estrogen regulated gene signatures in mammary epithelial cells (MECs). Among these was the protein tyrosine phosphatase, non-receptor type 5 (Ptpn5). We show that Ptpn5 is a novel tamoxifen regulated target gene which is upregulated in MECs after transient tamoxifen exposure and displays tumor suppressor activity in human breast cancer cells. Further, PTPN5 expression is strongly associated with good clinical outcome in tamoxifen treated human breast cancer patients suggesting that PTPN5 may represent a novel biomarker of tamoxifen response in human breast cancer. PMID- 29590205 TI - A Middle Palaeolithic wooden digging stick from Aranbaltza III, Spain. AB - Aranbaltza is an archaeological complex formed by at least three open-air sites. Between 2014 and 2015 a test excavation carried out in Aranbaltza III revealed the presence of a sand and clay sedimentary sequence formed in floodplain environments, within which six sedimentary units have been identified. This sequence was formed between 137-50 ka, and includes several archaeological horizons, attesting to the long-term presence of Neanderthal communities in this area. One of these horizons, corresponding with Unit 4, yielded two wooden tools. One of these tools is a beveled pointed tool that was shaped through a complex operational sequence involving branch shaping, bark peeling, twig removal, shaping, polishing, thermal exposition and chopping. A use-wear analysis of the tool shows it to have traces related with digging soil so it has been interpreted as representing a digging stick. This is the first time such a tool has been identified in a European Late Middle Palaeolithic context; it also represents one of the first well-preserved Middle Palaeolithic wooden tool found in southern Europe. This artefact represents one of the few examples available of wooden tool preservation for the European Palaeolithic, allowing us to further explore the role wooden technologies played in Neanderthal communities. PMID- 29590206 TI - Worldwide increased prevalence of human adenovirus type 3 (HAdV-3) respiratory infections is well correlated with heterogeneous hypervariable regions (HVRs) of hexon. AB - Human adenovirus type 3 (HAdV-3) respiratory infections occurs worldwide in both children and adults, leading to severe morbidity and mortality, particularly in the paediatric age group and especially in neonates. During HAdV infection, neutralizing antibodies are formed against the epitopes located in the hyper variable regions (HVRs) of the hexon protein. These neutralizing antibodies provide protection against reinfection by viruses of the same type. Therefore it is reasonable to speculate that variations of HAdV-3 in the HVRs could impair the immunity acquired by previous infection with a different strain with variation in its HVRs. HAdV-3 has recently become the major agent of acute respiratory infection worldwide, being responsible for 15% to 87% of all adenoviral respiratory infections. However, despite the increased prevalence of HAdV-3 as respiratory pathogen, the diversity of hexon proteins in circulating strains remains unexplored. This study was designed to explore the variation in HVRs of hexon among globally distributed strains of HAdV-3 as well as to discover possible relationship among them, thus possibly shedding light on the cause for the increased prevalence of HAdV-3. In this study, for the first time we analysed the hexon proteins of all 248 available strains of HAdV-3 from the NCBI database and compared them with those of the HAdV-3 prototype (GB stain). We found that the HVRs of HAdV-3 strains circulating worldwide were highly heterogeneous and have been mutating continuously since -their original isolation. Based on their immense heterogeneity, the strains can be categorized into 25 hexon variants (3Hv 1 to 3Hv-25), 4 of which (3Hv-1 to 3Hv-4) comprises 80% of the strains. This heterogeneity may explain why HAdV-3 has become the most prevalent HAdVs type worldwide. The heterogeneity of hexon proteins also shows that the development of a vaccine against HAdV-3 might be challenging. The data on hexon variants provided here may be useful for the future epidemiological study of HAdV-3 infection. PMID- 29590208 TI - Rome in its setting. Post-glacial aggradation history of the Tiber River alluvial deposits and tectonic origin of the Tiber Island. AB - The Tiber valley is a prominent feature in the landscape of ancient Rome and an important element for understanding its urban development. However, little is known about the city's original setting. Our research provides new data on the Holocene sedimentary history and human-environment interactions in the Forum Boarium, the location of the earliest harbor of the city. Since the Last Glacial Maximum, when the fluvial valley was incised to a depth of tens of meters below the present sea level, 14C and ceramic ages coupled with paleomagnetic analysis show the occurrence of three distinct aggradational phases until the establishment of a relatively stable alluvial plain at 6-8 m a.s.l. during the late 3rd century BCE. Moreover, we report evidence of a sudden and anomalous increase in sedimentation rate around 2600 yr BP, leading to the deposition of a 4-6m thick package of alluvial deposits in approximately one century. We discuss this datum in the light of possible tectonic activity along a morpho-structural lineament, revealed by the digital elevation model of this area, crossing the Forum Boarium and aligned with the Tiber Island. We formulate the hypothesis that fault displacement along this structural lineament may be responsible for the sudden collapse of the investigated area, which provided new space for the observed unusually large accumulation of sediments. We also posit that, as a consequence of the diversion of the Tiber course and the loss in capacity of transport by the river, this faulting activity triggered the origin of the Tiber Island. PMID- 29590207 TI - Dynamics of tandemly repeated DNA sequences during evolution of diploid and tetraploid botiid loaches (Teleostei: Cobitoidea: Botiidae). AB - Polyploidization has played an important role in the evolution of vertebrates, particularly at the base of Teleostei-an enormously successful ray-finned fish group with additional genome doublings on lower taxonomic levels. The investigation of post-polyploid genome dynamics might provide important clues about the evolution and ecology of respective species and can help to decipher the role of polyploidy per se on speciation. Few studies have attempted to investigate the dynamics of repetitive DNA sequences in the post-polyploid genome using molecular cytogenetic tools in fishes, though recent efforts demonstrated their usefulness. The demonstrably monophyletic freshwater loach family Botiidae, branching to evolutionary diploid and tetraploid lineages separated >25 Mya, offers a suited model group for comparing the long-term repetitive DNA evolution. For this, we integrated phylogenetic analyses with cytogenetical survey involving Giemsa- and Chromomycin A3 (CMA3)/DAPI stainings and fluorescence in situ hybridization with 5S/45S rDNA, U2 snDNA and telomeric probes in representative sample of 12 botiid species. The karyotypes of all diploids were composed of 2n = 50 chromosomes, while majority of tetraploids had 2n = 4x = 100, with only subtle interspecific karyotype differences. The exceptional karyotype of Botia dario (2n = 4x = 96) suggested centric fusions behind the 2n reduction. Variable patterns of FISH signals revealed cases of intraspecific polymorphisms, rDNA amplification, variable degree of correspondence with CMA3+ sites and almost no phylogenetic signal. In tetraploids, either additivity or loci gain/loss was recorded. Despite absence of classical interstitial telomeric sites, large blocks of interspersed rDNA/telomeric regions were found in diploids only. We uncovered different molecular drives of studied repetitive DNA classes within botiid genomes as well as the advanced stage of the re-diploidization process in tetraploids. Our results may contribute to link genomic approach with molecular cytogenetic analyses in addressing the origin and mechanism of this polyploidization event. PMID- 29590209 TI - Patients with atrial fibrillation and permanent pacemaker: Temporal changes in patient characteristics and pharmacotherapy. AB - BACKGROUND: The management of patients with non-valvular atrial fibrillation (NVAF) with rate-lowering or anti-arrhythmic drugs has markedly changed over the last decade, but it is unknown how these changes have affected patients with NVAF with a permanent pacemaker (PPM). METHODS: Through Danish nationwide registries, patients with NVAF and a PPM were identified from 2001 to 2012. Changes in concomitant pharmacotherapy and comorbidities were tested using the Cochran Armitage trend test and linear regression. Patients with NVAF were identified to calculate the proportional amount of PPM implants. RESULTS: A total of 12,231 NVAF patients with a PPM were included in the study, 55.6% of which were men. Median age was 78 years (interquartile range 70-84). From 2001 to 2012, the number of NVAF patients with a PPM increased from 850 to 1344, while the number of NVAF patients increased from 67,478 to 127,261. Thus, the proportional amount of NVAF patients with a PPM decreased from 1.3% to 1.1% (p = 0.015). Overall 45.9% had atrial fibrillation (AF) duration less than one year and the proportion declined from 55.5% to 42.4% (p <0.001). Diabetes mellitus increased from 7.2% to 16.8% (p <0.001). Heart failure (HF) decreased from 36.7% to 29.3% (p = 0.010) and ischemic heart disease (IHD) decreased from 32.4% to 26.1% (p <0.001). Beta blocker use increased from 38.1% to 58.0% (p <0.001), while digoxin and anti arrhythmic drug use decreased over time. CONCLUSION: From 2001 to 2012, the absolute number of NVAF patients with a PPM increased while the proportional amount decreased. The number of NVAF patients receiving a PPM within one year of AF diagnosis decreased. The prevalence of DM increased, while the prevalence of HF and IHD was high but decreasing. The use of beta-blockers increased markedly, while use of digoxin and anti-arrhythmic drugs decreased over time.

PMID- 29590211 TI - Income-based inequalities in caregiving time and depressive symptoms among older family caregivers under the Japanese long-term care insurance system: A cross sectional analysis. AB - AIM: Long-term care systems may alleviate caregiver burdens, particularly for those with fewer resources. However, it remains unclear whether socioeconomic disparity in caregiver burdens exists under a public, universal long-term care insurance (LTCI) system. This study examined income-based inequalities in caregiving time and depressive symptoms in Japanese older family caregivers. We further compared inequality in depressive symptoms with that of non-caregivers to evaluate whether family caregiving exacerbates this disparity. METHODS: Data were obtained from a cross-sectional, nationwide survey conducted by the Japan Gerontological Evaluation Study in 2013. Participants were functionally independent older adults aged >=65 years (N = 21,584). Depressive symptoms were assessed using the Geriatrics Depression Scale (GDS); caregiving hours per week, household income, and other covariates were also assessed. RESULTS: Family caregivers occupied 8.3% of the total. A Poisson regression model revealed that caregivers in lower income groups (compared to those in the highest) were 1.32 to 1.95 and 1.63 to 2.68 times more likely to engage in >=36 and >=72 hours/week of caregiving, respectively. As for the GDS (>=5), an excess risk was found in the caregivers in lower (compared to higher) income groups (adjusted prevalence ratio: 1.57-3.10). However, an interaction effect of income by caregiving role indicated no significant difference in inequality between caregivers and non caregivers (p = .603). The excess risk for GDS (>=5) in the caregivers compared to non-caregivers was observed across income groups. CONCLUSIONS: Our findings revealed a possible disparity in family caregivers under the public LTCI system. Further studies should examine factors associated with longer caregiving hours in lower income households. Our findings also suggest the necessity for more efforts to alleviate depressive symptoms in family caregivers under the LTCI system regardless of income level, rather than exclusively supporting those with a low income. PMID- 29590212 TI - Cardiorespiratory fitness and the metabolic syndrome: Roles of inflammation and abdominal obesity. AB - OBJECTIVE: Individuals with metabolic syndrome have increased risk of type 2 diabetes and cardiovascular disease. We aimed to test the hypothesis that a high level of cardiorespiratory fitness (CR-fitness), counteracts accumulation of visceral fat, decreases inflammation and lowers risk factors of the metabolic syndrome. METHOD: The study sample included 1,293 Danes (age 49-52 years) who from 2009 to 2011 participated in the Copenhagen Aging and Midlife Biobank, including a questionnaire, physical tests, and blood samples. Multiple linear regression models were performed with CR-fitness as exposure and plasma levels of cytokines and high sensitive C-reactive protein as outcomes and measures of abdominal obesity were added to test if they explained the potential association. Similarly, multiple linear regression models were performed with CR-fitness as exposure and factors of the metabolic syndrome as outcomes and the potential explanation by inflammatory biomarkers were tested. All models were adjusted for the effect of age, sex, smoking, alcohol consumption, socio-economic status, and acute inflammatory events within the preceding two weeks. RESULTS: CR-fitness was inversely associated with high sensitive C-reactive protein, Interleukin (IL)-6, and IL-18, and directly associated with the anti-inflammatory cytokine IL-10, but not associated with tumor necrosis factor alpha, interferon gamma or IL-1beta. Abdominal obesity could partly explain the significant associations. Moreover, CR fitness was inversely associated with an overall metabolic syndrome score, as well as triglycerides, glycated haemoglobin A1c, systolic blood pressure, diastolic blood pressure and directly associated with high-density lipoprotein. Single inflammatory biomarkers and a combined inflammatory score partly explained these associations. CONCLUSION: Data suggest that CR-fitness has anti inflammatory effects that are partly explained by a reduction in abdominal obesity and a decrease in the metabolic syndrome risk profile. The overall inflammatory load was mainly driven by high sensitive C-reactive protein and IL 6.

AB - Vagus nerve stimulation (VNS) is an approved therapy for treatment of epilepsy and depression. While also shown to be promising in several preclinical and clinical studies to treat cardiovascular diseases, optimal therapeutic stimulation paradigms are still under investigation. Traditionally, parameters such as frequency, current, and duty cycle are used to adjust the efficacy of VNS therapy. This study explored the effect of novel stochastic VNS (S-VNS) on acute heart rate (HR) dynamics. The effect of S-VNS was evaluated in Sprague Dawley rats by comparing the acute HR and HR variability (HRV) responses to standard, periodic VNS (P-VNS) across different frequencies (FREQs, 10-30 Hz). Our results demonstrate that both S-VNS and P-VNS produced negative chronotropic effects in a FREQ-dependent manner with S-VNS inducing a significantly smaller drop in HR at 10 Hz and 20 Hz compared to P-VNS (p<0.05). S-VNS demonstrated a FREQ-dependent drop in the SD1/SD2 ratio, a measure of HRV, which was absent in P-VNS, suggesting that S-VNS may acutely modulate the nonlinear relationship between short- and long-term HRV. In conclusion, S-VNS is a novel stimulation procedure that may provide different physiological outcomes from standard P-VNS, as indicated by our analysis of HR dynamics. Our study provides a rationale for further detailed investigations into the therapeutic potential of S-VNS as a novel neuromodulation technique. PMID- 29590216 TI - Perception of the importance of chemistry research papers and comparison to citation rates. AB - Chemistry researchers are frequently evaluated on the perceived significance of their work with the citation count as the most commonly-used metric for gauging this property. Recent studies have called for a broader evaluation of significance that includes more nuanced bibliometrics as well as altmetrics to more completely evaluate scientific research. To better understand the relationship between metrics and peer judgements of significance in chemistry, we have conducted a survey of chemists to investigate their perceptions of previously published research. Focusing on a specific issue of the Journal of the American Chemical Society published in 2003, respondents were asked to select which articles they thought best matched importance and significance given several contexts: highest number of citations, most significant (subjectively defined), most likely to share among chemists, and most likely to share with a broader audience. The answers to the survey can be summed up in several observations. The ability of respondents to predict the citation counts of established research is markedly lower than the ability of those counts to be predicted by the h-index of the corresponding author of each article. This observation is conserved even when only considering responses from chemists whose expertise falls within the subdiscipline that best describes the work performed in an article. Respondents view both cited papers and significant papers differently than papers that should be shared with chemists. We conclude from our results that peer judgements of importance and significance differ from metrics based measurements, and that chemists should work with bibliometricians to develop metrics that better capture the nuance of opinions on the importance of a given piece of research. PMID- 29590215 TI - The draft genome of Kipferlia bialata reveals reductive genome evolution in fornicate parasites. AB - The fornicata (fornicates) is a eukaryotic group known to consist of free-living and parasitic organisms. Genome datasets of two model fornicate parasites Giardia intestinalis and Spironucleus salmonicida are well annotated, so far. The nuclear genomes of G. intestinalis assemblages and S. salmonicida are small in terms of the genome size and simple in genome structure. However, an ancestral genomic structure and gene contents, from which genomes of the fornicate parasites have evolved, remains to be clarified. In order to understand genome evolution in fornicates, here, we present the draft genome sequence of a free-living fornicate, Kipferlia bialata, the divergence of which is earlier than those of the fornicate parasites, and compare it to the genomes of G. intestinalis and S. salmonicida. Our data show that the number of protein genes and introns in K. bialata genome are the most abundant in the genomes of three fornicates, reflecting an ancestral state of fornicate genome evolution. Evasion mechanisms of host immunity found in G. intestinalis and S. salmonicida are absent in the K. bialata genome, suggesting that the two parasites acquired the complex membrane surface proteins on the line leading to the common ancestor of G. intestinalis and S. salmonicida after the divergence from K. bialata. Furthermore, the mitochondrion related organelles (MROs) of K. bialata possess more complex suites of metabolic pathways than those in Giardia and in Spironucleus. In sum, our results unveil the process of reductive evolution which shaped the current genomes in two model fornicate parasites G. intestinalis and S. salmonicida. PMID- 29590217 TI - BBS1 is involved in retrograde trafficking of ciliary GPCRs in the context of the BBSome complex. AB - Protein trafficking within cilia is mediated by the intraflagellar transport (IFT) machinery composed of large protein complexes. The BBSome consists of eight BBS proteins encoded by causative genes of Bardet-Biedl syndrome (BBS), and has been implicated in the trafficking of ciliary membrane proteins, including G protein-coupled receptors (GPCRs), by connecting the IFT machinery to cargo GPCRs. Membrane recruitment of the BBSome to promote cargo trafficking has been proposed to be regulated by the Arf-like small GTPase ARL6/BBS3, through its interaction with the BBS1 subunit of the BBSome. We here investigated how the BBSome core subcomplex composed of BBS1, BBS2, BBS7, and BBS9 assembles and interacts with ARL6, and found that the ARL6-BBS1 interaction is reinforced by BBS9. BBS1-knockout (KO) cells showed defects in the ciliary entry of other BBSome subunits and ARL6, and in ciliary retrograde trafficking and the export of the GPCRs, Smoothened and GPR161. The trafficking defect of these GPCRs was rescued by the exogenous expression of wild-type BBS1, but not by its mutant lacking BBS9-binding ability. Our data thus indicate that the intact BBSome is required for retrograde trafficking of GPCRs out of cilia. PMID- 29590218 TI - Interaction of HuDA and PABP at 5'UTR of mouse insulin2 regulates insulin biosynthesis. AB - Understanding the regulation of insulin biosynthesis is important as it plays a central role in glucose metabolism. The mouse insulin gene2 (Ins2) has two splice variants; long (Ins2L) and short (Ins2S), that differ only in their 5'UTR sequence and Ins2S is the major transcript which translate more efficiently as compared to Ins2L. Here, we show that cellular factors bind preferentially to the Ins2L 5'UTR, and that PABP and HuD can bind to Ins2 splice variants and regulate its translation. In vitro binding assay with insulin 5'UTR and different HuD isoforms indicate that the 'N' terminal region of HuD is important for RNA binding and insulin translation repression. Using reporter assay we showed that specifically full-length HuD A isoform represses translation of reporter containing insulin 5'UTR. We further show that PABP and HuD interact with each other in RNA-dependent manner and this interaction is affected by glucose and PDI (5'UTR associated translation activator). These results suggest that PABP interacts with HuD in basal glucose conditions making translation inhibitory complex, however upon glucose stimulation this association is affected and PABP is acted upon by PDI resulting in stimulation of insulin translation. Together, our findings snapshot the mechanism of post-transcriptional regulation of insulin biosynthesis. PMID- 29590219 TI - Personalized survival predictions via Trees of Predictors: An application to cardiac transplantation. AB - BACKGROUND: Risk prediction is crucial in many areas of medical practice, such as cardiac transplantation, but existing clinical risk-scoring methods have suboptimal performance. We develop a novel risk prediction algorithm and test its performance on the database of all patients who were registered for cardiac transplantation in the United States during 1985-2015. METHODS AND FINDINGS: We develop a new, interpretable, methodology (ToPs: Trees of Predictors) built on the principle that specific predictive (survival) models should be used for specific clusters within the patient population. ToPs discovers these specific clusters and the specific predictive model that performs best for each cluster. In comparison with existing clinical risk scoring methods and state-of-the-art machine learning methods, our method provides significant improvements in survival predictions, both post- and pre-cardiac transplantation. For instance: in terms of 3-month survival post-transplantation, our method achieves AUC of 0.660; the best clinical risk scoring method (RSS) achieves 0.587. In terms of 3 year survival/mortality predictions post-transplantation (in comparison to RSS), holding specificity at 80.0%, our algorithm correctly predicts survival for 2,442 (14.0%) more patients (of 17,441 who actually survived); holding sensitivity at 80.0%, our algorithm correctly predicts mortality for 694 (13.0%) more patients (of 5,339 who did not survive). ToPs achieves similar improvements for other time horizons and for predictions pre-transplantation. ToPs discovers the most relevant features (covariates), uses available features to best advantage, and can adapt to changes in clinical practice. CONCLUSIONS: We show that, in comparison with existing clinical risk-scoring methods and other machine learning methods, ToPs significantly improves survival predictions both post- and pre cardiac transplantation. ToPs provides a more accurate, personalized approach to survival prediction that can benefit patients, clinicians, and policymakers in making clinical decisions and setting clinical policy. Because survival prediction is widely used in clinical decision-making across diseases and clinical specialties, the implications of our methods are far-reaching.

AB - The aim of this study was to investigate the survival rate of implants immediately placed in fresh extraction sockets of molars in the maxilla and mandible with a single-stage procedure. A total of 102 patients were treated, and 107 implants (53 in the maxilla and 54 in the mandible) were placed in a fresh molar extraction socket and connected to a healing abutment. After a mean follow up of 3 years (range: 1 to 6 years) 1 implant failed, for a cumulative success rate of 99.06% (98.11% for the mandible and 100% for the maxilla). The results of this study support placement of an implant immediately after the extraction of a molar, applying a single-stage procedure. PMID- 29590220 TI - A fatty acid analogue targeting mitochondria exerts a plasma triacylglycerol lowering effect in rats with impaired carnitine biosynthesis. AB - L-carnitine is important for the catabolism of long-chain fatty acids in the mitochondria. We investigated how the triacylglycerol (TAG)-lowering drug 2 (tridec-12-yn-1-ylthio)acetic acid (1-triple TTA) influenced lipid metabolism in carnitine-depleted, 3-(2,2,2-trimethylhydrazinium)propionate dehydrate (Mildronate; meldonium)-treated male Wistar rats. As indicated, carnitine biosynthesis was impaired by Mildronate. However, TAG levels of both plasma and liver were decreased by 1-triple TTA in Mildronate-treated animals. This was accompanied by increased gene expression of proteins involved in mitochondrial activity and proliferation and reduced mRNA levels of Dgat2, ApoB and ApoCIII in liver. The hepatic energy state was reduced in the group of Mildronate and 1 triple TTA as reflected by increased AMP/ATP ratio, reduced energy charge and induced gene expression of uncoupling proteins 2 and 3. The increase in mitochondrial fatty acid oxidation was observed despite low plasma carnitine levels, and was linked to strongly induced gene expression of carnitine acetyltransferase, translocase and carnitine transporter, suggesting an efficient carnitine turnover. The present data suggest that the plasma TAG-lowering effect of 1-triple TTA in Mildronate-treated rats is not only due to increased mitochondrial fatty acid oxidation reflected by increased mitochondrial biogenesis, but also to changes in plasma clearance and reduced TAG biosynthesis. PMID- 29590223 TI - Clinical Guidelines for Implant Treatment in Patients with Down Syndrome. AB - This study evaluated implant outcome in patients with Down syndrome (DSPs) and provides clinical guidelines to maximize treatment outcome. A total of 57 implants were placed in eight DSPs. During follow-up, implant survival was recorded and crestal bone level was evaluated when possible. After a mean follow up time of 5 years, six patients with 45 implants were evaluated and an implant survival rate of 84.4% was recorded. A mean crestal bone loss of 1.7 mm (SD 0.9) was measured in three patients around 20 implants. Down syndrome is not a contraindication to dental implant placement, but multiple complicating factors yield reduced implant survival. PMID- 29590221 TI - Andexanet alfa effectively reverses edoxaban anticoagulation effects and associated bleeding in a rabbit acute hemorrhage model. AB - INTRODUCTION: Increasing use of factor Xa (FXa) inhibitors necessitates effective reversal agents to manage bleeding. Andexanet alfa, a novel modified recombinant human FXa, rapidly reverses the anticoagulation effects of direct and indirect FXa inhibitors. OBJECTIVE: To evaluate the ability of andexanet to reverse anticoagulation in vitro and reduce bleeding in rabbits administered edoxaban. MATERIALS AND METHODS: In vitro studies characterized the interaction of andexanet with edoxaban and its ability to reverse edoxaban-mediated anti-FXa activity. In a rabbit model of surgically induced, acute hemorrhage, animals received edoxaban vehicle+andexanet vehicle (control), edoxaban (1 mg/kg)+andexanet vehicle, edoxaban+andexanet (75 mg, 5-minute infusion, 20 minutes after edoxaban), or edoxaban vehicle+andexanet prior to injury. RESULTS: Andexanet bound edoxaban with high affinity similar to FXa. Andexanet rapidly and dose-dependently reversed the effects of edoxaban on FXa activity and coagulation pharmacodynamic parameters in vitro. In edoxaban-anticoagulated rabbits, andexanet reduced anti-FXa activity by 82% (from 548+/-87 to 100+/-41 ng/ml; P<0.0001), mean unbound edoxaban plasma concentration by ~80% (from 100+/-10 to 21+/-6 ng/ml; P<0.0001), and blood loss by 80% vs. vehicle (adjusted for control, 2.6 vs. 12.9 g; P = 0.003). The reduction in blood loss correlated with the decrease in anti-FXa activity (r = 0.6993, P<0.0001) and unbound edoxaban (r = 0.5951, P = 0.0035). CONCLUSION: These data demonstrate that andexanet rapidly reversed the anticoagulant effects of edoxaban, suggesting it could be clinically valuable for the management of acute and surgery-related bleeding. Correlation of blood loss with anti-FXa activity supports the use of anti-FXa activity as a biomarker for assessing anticoagulation reversal in clinical trials. PMID- 29590224 TI - Effect of Biologic Aging of Implants on Osseointegration in the Dog. AB - The objective of this preclinical study was to investigate the effect of biologic aging of implants on osseointegration in the canine. According to multiple comparisons, there was a significant difference in bone-to-implant contact (BIC) between control implants placed 6 months after manufacture and 2-week-old implants (P = .016), and between control and newly prepared implants with acid etching (P = .019). However, there was no significant difference in BIC between newly prepared implants with acid-etching and 2-week-old implants. In all groups, BIC at 12 weeks was significantly higher than at week 4 (P < .05). There were no significant differences in bone volume (BV) regardless of area and time. Biologic aging of implants might affect osseointegration in the bone marrow zone at 4 weeks of healing. Although implant aging did not greatly affect BIC and BV at 12 weeks of healing in this study, further research is required to determine an appropriate period of biologic aging of implants that yields significant clinical effects. PMID- 29590225 TI - Periodontal Regenerative Treatment of Intrabony Defects in the Esthetic Zone Using Modified Vestibular Incision Subperiosteal Tunnel Access (M-VISTA). AB - Periodontal regenerative treatment of intrabony defects in the esthetic zone often poses a significant challenge to clinicians. Various materials and techniques have been proposed to achieve periodontal regeneration. This article presents modified vestibular incision subperiosteal tunnel access (M-VISTA) for treatment of intrabony defects in the esthetic zone. Two cases were treated using the proposed approach with enamel matrix derivatives and demineralized freeze dried bone allograft to optimize the regenerative outcomes without affecting the soft tissue profile in the esthetic zone. Two different indications were described with addition of acellular dermal matrix and specific suturing techniques based on each particular clinical scenario. Clinical and radiographic follow-up of 18 months revealed successful outcomes of the proposed minimally invasive approach with no postoperative gingival recession. Patient-centered outcomes were highlighted as another major consideration in periodontal regeneration. PMID- 29590226 TI - Spontaneous Correction of Accentuated Retraction of Maxillary Central Incisors After Autogenous Graft in Midline, Mesialization, and Lingual Torque of Incisor Roots. AB - In the present clinical case, the authors report the orthodontic treatment of an adult patient with Class II malocclusion with periodontal disease and extensive bone destruction in the anterior region of the median palatine suture. Before orthodontic treatment, the patient presented precarious oral health. The treatment proposed for the case was insertion of an autogenous graft and subsequent orthodontic movement of the teeth to the area of the graft. The results obtained were correction of the malocclusion with significant improvement in gingival retraction and smile esthetics. With this clinical case, it could be concluded that well-performed orthodontic treatment can improve periodontal condition. PMID- 29590228 TI - Relationship Between Serum Uric Acid and Incident Hypertension in Patients with Type 2 Diabetes. AB - BACKGROUND: Little is known about the relationship between high baseline serum uric acid (SUA) and incident hypertension in patients with type 2 diabetes (T2D). OBJECTIVES: To evaluate the ability of baseline SUA to predict the incidence of hypertension in non-hypertensive patients with T2D. METHODS: The association between SUA and mean 20-year incidence of hypertension was examined in 1,666 non hypertensive patients with T2D from Isfahan Endocrine and Metabolism Research Center outpatient clinics, Iran. The primary outcome was incident hypertension defined as systolic blood pressure (BP) of 140 mmHg or higher and/or diastolic BP 90 mmHg or higher and/or use of antihypertensive medications. The mean (standard error (SE)) age of participants was 49.4 years (0.25 years) with a mean (SE) duration of diabetes of 6.1 years (0.15 years) at initial registration. We used multiple logistic regression to estimate the odds ratio (OR) for the incidence of hypertension across quartiles of SUA, and plotted a receiver operating characteristic (ROC) curve to assess discrimination. RESULTS: The highest quartile of SUA was not associated with hypertension compared with the lowest quartile in multivariable adjusted models (OR: 1.22, 95% CI: 0.87, 1.73). The area under the ROC curve for SUA was 51.7% (95% CI: 48.9, 54.5). CONCLUSIONS: High initial SUA levels are not a predictor of incident hypertension in an Iranian T2D population. PMID- 29590227 TI - Polymeric Scaffolds for Pancreatic Tissue Engineering: A Review. AB - In recent years, there has been an alarming increase in the incidence of diabetes, with one in every eleven individuals worldwide suffering from this debilitating disease. As the available treatment options fail to reduce disease progression, novel avenues such as the bioartificial pancreas are being given serious consideration. In the past decade, the research focus has shifted towards the field of tissue engineering, which helps to design biological substitutes for repair and replacement of non-functional or damaged organs. Scaffolds constitute an integral part of tissue engineering; they have been shown to mimic the native extracellular matrix, thereby supporting cell viability and proliferation. This review offers a novel compilation of the recent advances in polymeric scaffolds, which are used for pancreatic tissue engineering. Furthermore, in this article, the design strategies for bioartificial pancreatic constructs and their future applications in cell-based therapy are discussed. PMID- 29590229 TI - Association of Oxytocin with Glucose Intolerance and Inflammation Biomarkers in Metabolic Syndrome Patients with and without Prediabetes. AB - OBJECTIVES: The aim of this study was to explore the differences in OXT levels in metabolic syndrome (MetS) subjects, newly diagnosed type 2 diabetes mellitus (T2D), and prediabetes subjects vs. MetS subjects without glucose intolerance (non-diabetic MetS). It was also intended to determine the relationship between plasma OXT levels and inflammatory markers in those subjects. METHODS: Along with 45 lean and normoglycemic controls, a total of 190 MetS subjects (61 men, 129 women) were enrolled. Colorimetric enzymatic assays of the following components were performed: plasma OXT, high-sensitivity C-reactive protein (hs-CRP), macrophage chemoattractant protein 1 (MCP-1), plasminogen activator inhibitor 1 (PAI-1), matrix metalloproteinase 9 (MMP-9), resistin, adiponectin, leptin, macrophage migration inhibitory factor (MIF), tumor necrosis factor alpha (TNF alpha), thrompospondin 1 (TSP-1), interleukin 10 (IL-10), interleukin 6 (IL-6), and glucagon. RESULTS: hsCRP, PAI-1, resistin, leptin-to-adiponection-ratio (LAR), TNF-alpha, TSP-1, and MIF were significantly higher in both MetS groups (prediabetic and T2DM) than in MetS-only subjects. Leptin and MMP-9 were significantly higher in the MetS-T2DM group (but not in MetS-prediabetics) vs. MetS-only subjects. Conversely adiponectin, OXT, MCP-1, and IL-10 were significantly lower in both MetS groups (prediabetic and T2DM) than in MetS-only subjects. There was no marked discrepancy in either glucagon or IL-6 levels among the three MetS groups. In the entire MetS study population, OXT correlated substantially and proportionally with MCP-1, IL-10, and IL-6; it correlated negatively with HbA1c, fasting plasma glucose (FPG), PAI-1, MMP-9, TNF-alpha, TSP 1, resistin, adiponectin, leptin, LAR, and MIF. No association could be observed between OXT and glucagon. CONCLUSIONS: OXT may be a substantial surrogate predictive/prognostic tool and putative pharmacotherapeutic target in metabolic anomalies and related disorders. PMID- 29590230 TI - Duration of Type 2 Diabetes is a Predictor of Elevated Plantar Foot Pressure. AB - AIMS: Elevated plantar pressure is considered a significant risk factor for ulceration in diabetes mellitus. The aim of this study was to determine whether duration of diabetes could affect plantar pressure in patients with no known significant comorbidity or foot pathology. METHODS: Participants with type 2 diabetes, but without known confounding factors that could alter peak pressure, were matched for age, weight, and gender and categorized into 3 groups of diabetes duration: group 1 (1-5 yr), group 2 (6-10 yr), and group 3 (11-15 yr). Plantar pressures were recorded utilizing a two-step protocol at a self-selected speed. RESULTS: One-way analysis of variance (ANOVA) revealed significant differences in mean peak plantar pressures between the three groups under the 2nd - 4th metatarsophalangeal joint (MPJ) region of interest (ROI) (p = 0.012 and p = 0.022, respectively) and left heel (p = 0.049). Also, a significant difference in mean pressure-time integral under the left 2nd - 4th MPJ ROI (p = 0.021) and right heel (p = 0.048) was observed. Regression analysis confirmed that mean peak plantar pressures in the first group (but not in the second group) were significantly lower than in the third group (p = 0.005). CONCLUSIONS: As the duration of diabetes increased, peak plantar pressure increased significantly under the 2nd - 4th MPJ ROIs. These findings suggest that clinicians should make more use of pressure mapping technology as part of their clinical management plan in patients with diabetes >10 yr, even if they have no complications or deformities, to preserve functional limbs in this high-risk population. PMID- 29590232 TI - The cause of abdominal mass in a child with celiac disease: Rapunzel syndrome. A case report. AB - CONTEXT: Rapunzel syndrome is a rare form of gastric trichobezoar that develops through outstretching of the bezoar from the stomach to the intestine. CASE REPORT: A 12-year-old girl who had been diagnosed with celiac disease six years earlier was brought to the department of pediatric gastroenterology because of abdominal distension. A palpable mass was detected. A trichobezoar that stretched to the small intestine was removed surgically. The patient was diagnosed as having anxiety and depressive disorder, and treatment started. Following the treatment, her previous trichophagia completely disappeared. CONCLUSION: Presence of trichobezoar should be kept in mind, especially when young girls who have psychiatric problems suffer from gastrointestinal symptoms. PMID- 29590231 TI - Association of Socio-Environmental Determinants with Diabetes Prevalence in the Athens Metropolitan Area, Greece: A Spatial Analysis. AB - OBJECTIVES: The aim of this study was to investigate the spatial variation of diabetes in relation to the geographical variability of socio-environmental characteristics in the urban districts of Athens. METHODS: A sample of 2,445 individuals from the greater area of Athens was randomly enrolled in the ATTICA study between 2001 and 2002. Diabetes was defined according to American Diabetes Association criteria. Geographical and statistical analyses were applied to examine the relationship between diabetes prevalence and factors related to education, economic status, population density, immigrant status, and availability of urban green areas. Diabetes prevalence and socio-environmental factor mapping was based on the Geographic Information Systems (GIS) technology. Variograms and spatial quasi-Poisson regression analysis evaluated the associations of diabetes with the socio-environmental variables at the municipal level. RESULTS: According to the geographical analysis and mapping, the highest proportions of people with diabetes were found in the West sector and in one district of the East and South sector each. Regression analysis revealed that the proportion of inhabitants with higher education is negatively correlated with diabetes prevalence in the regional areas of Athens. CONCLUSIONS: The study revealed that socio-environmental status in residential areas, especially educational and economic levels, is correlated with diabetes prevalence at the aggregate level. These correlations may reflect socio-economic segregation patterns at the district level, and different prevalence rates of diabetes among individuals with higher income and educational levels. PMID- 29590234 TI - 30 years of the Brazilian National Health System. PMID- 29590233 TI - Oral squamous cell carcinoma: a clinicopathological study on 194 cases in northeastern Brazil. A cross-sectional retrospective study. AB - BACKGROUND: Only a few studies have evaluated the clinicopathological features of oral squamous cell carcinoma (SCC) in Brazil, and most were conducted in the most industrialized region of the country, i.e. the southeastern region. The aim of this study was to evaluate the clinicopathological features of this malignant neoplasm in northeastern Brazil. DESIGN AND SETTING: Retrospective study performed in an oral pathology laboratory in Recife, Brazil. METHODS: All cases of oral SCC that occurred between 2000 and 2015 were studied. Clinical data were recorded and histological slides were reviewed. Statistical analysis was performed using the chi-square test (P <= 0.05). RESULTS: A total of 194 cases were evaluated. The male-to-female ratio was 1.5:1. The mean age was 65.4 years, and only 6.6% of the cases occurred in patients younger than 41 years. Most tumors consisted of well-differentiated SCC (54.6%). CONCLUSIONS: The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals. PMID- 29590235 TI - Effectiveness of dog collars impregnated with 4% deltamethrin in controlling visceral leishmaniasis in Lutzomyia longipalpis (Diptera: Psychodidade: Phlebotominae) populations. AB - BACKGROUND: There is little information on the effect of using deltamethrin impregnated dog collars for the control of canine visceral leishmaniasis. OBJECTIVES: The objective of this study was to evaluate the effectiveness of the use of 4% deltamethrin-impregnated collars (Scalibor(r)) in controlling visceral leishmaniasis in Lutzomyia longipalpis by comparing populations in intervention and non-intervention areas. METHODS: Phlebotomine flies were captured over 30 months in four neighbourhoods with intense visceral leishmaniasis transmission in Fortaleza and Montes Claros. We calculated the rates of domicile infestation, relative abundance of Lu. longipalpis, and Lu. longipalpis distribution in each site, capture location (intra- and peridomestic locations) and area (intervention and non-intervention areas). FINDINGS: In the control area in Fortaleza, the relative abundance of Lu. longipalpis was 415 specimens at each capture site, whereas in the intervention area it was 159.25; in Montes Claros, the relative abundance was 5,660 specimens per capture site in the control area, whereas in the intervention area it was 2,499.4. The use of dog collars was associated with a reduction in captured insects of 15% (p = 0.004) and 60% (p < 0.001) in Montes Claros and Fortaleza, respectively. MAIN CONCLUSIONS: We observed a lower vector abundance in the intervention areas, suggesting an effect of the insecticide impregnated collars. PMID- 29590237 TI - Comparative study of systemic early postoperative inflammatory response among elderly and non-elderly patients undergoing laparoscopic cholecystectomy. AB - OBJECTIVE: to evaluate and compare the early postoperative period systemic inflammatory response between elderly and non-elderly patients submitted to laparoscopic cholecystectomy, mainly performing a quantitative analysis of interleukin-6 (IL-6), a marker of inflammatory activity systemic. METHODS: we compared a series of cases over a period of six months at the Gaffree and Guinle University Hospital of the Federal University of the State of Rio de Janeiro, involving 60 patients submitted to elective laparoscopic cholecystectomy. We used non-probabilistic sampling for convenience, selecting, from the inclusion criteria, the first 30 patients aged 18-60 years, who comprised group I, and 30 patients with age equal to or greater than 60 years, who formed group II. RESULTS: the 60 patients involved were followed for at least 30 days after surgery and there were no complications. There was no conversion to open surgery. The values of the medians found in the IL-6 dosages for the preoperative period, three hours after the procedure and 24 hours after surgery were, respectively, 3.1 vs. 4.7 pg/ml, 7.3 vs. 14.1 pg/ml and 4.4 vs 13.3 pg/ml. CONCLUSION: Elderly patients were more responsive to surgical trauma and had elevated IL-6 levels for a longer period than the non-elderly group. PMID- 29590236 TI - Evaluation of the recombinant antigens Wb14 and WbT for the capture antibody diagnosis of lymphatic filariasis. AB - BACKGROUND: Lymphatic filariasis (LF) is a parasitic disease caused mainly by the Wuchereria bancrofti worm and that affects up to 120 million people worldwide. LF is the second cause of chronic global deformity, responsible for 15 million people with lymphedema (elephantiasis) and 25 million men with scrotal hydrocele. Its diagnosis is still associated with numerous difficulties, such as the sample collection periods (microfilaria nocturnal periodicity) and limited diagnostic kits. OBJECTIVES: The aim of this work was to evaluate two recombinant antigens (Wb14 and WbT) as part of an enzyme-linked immunosorbent assay (ELISA) based antibody capture tests for LF. METHODS: The recombinant antigens rWb14 and rWbT were expressed in Escherichia coli BL21 and an antibody capture ELISA was performed. For this, sera were used from microfilaremic individuals with W. bancrofti (MF), chronic pathology (CP), individuals infected with Strongyloides (SP) and healthy controls from endemic (EN) and non-endemic (NE) areas. FINDINGS: Both tests showed similar results, with 90% sensitivity and 96.6% specificity. In comparison with the BM14 ELISA commercial test, the Wb14 and WbT antigens performed with identical sensitivity but greater specificity. Reduced positivity with the CP suggested a potential to monitor cure. This was not confirmed, however, when sera from individuals up to seven years after treatment were assayed. MAIN CONCLUSIONS: The Wb14 and WbT ELISAs were considered efficient and promising diagnostic tests. Due to the importance of antibody capture analysis to evaluate the Global Program to Eliminate Lymphatic Filariasis (GPELF), the tests proposed here appear as great alternatives to the available commercial system.

AB - In a current scenario where trauma injury and its consequences account for 9% of the worlds causes of death, the management of non-compressible torso hemorrhage can be problematic. With the improvement of medicine, the approach of these patients must be accurate and immediate so that the consequences may be minimal. Therefore, aiming the ideal method, studies have led to the development of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA). This procedure has been used at select trauma centers as a resuscitative adjunct for trauma patients with non-compressible torso hemorrhage. Although the use of this technique is increasing, its effectiveness is still not clear. This article aims, through a detailed review, to inform an updated view about this procedure, its technique, variations, benefits, limitations and future.

METHOD: Technological production research of online course guided by the ADDIE (Analysis, Design, Development, Implementation, Evaluation) instructional design model based on Andragogy and the Meaningful Learning Theory. The online course was constructed in the platform Moodle, previously assessed by a group of experts, and then presented to the students of the Nursing School of the University of Sao Paulo, who assessed it at the end of the course. RESULTS: The course was evaluated by the experts and obtained a mean score of 0.92 (SD 0.15), considered as good quality (between 0.90-0.94), and by the students, with a mean score of 0.95 (SD 0.03), considered as high quality (0.95-1.00). CONCLUSION: The instructional design used was found to be appropriate to the development of the online course. As an active educational strategy, it contributed to the learning on Basic Life Support during cardiac arrest-related procedures in adults. In view of the need for technological innovations in education and systematization of care in cardiopulmonary resuscitation, the online course allows the establishment of continuous improvement processes in the quality of resuscitation in the care provided by students and professionals.

PMID- 29590241 TI - "We only have access as a favor, don't we?" The perception of homeless population on the human rights to water and sanitation. AB - The human rights to water and sanitation (HRWS) state that all human beings have the right to safe access to water and sanitation in a non-discriminatory manner. However, vulnerable populations frequently have these rights violated, which impacts their health and quality of life, exacerbating social exclusion as in the case of homeless people. In Belo Horizonte, Minas Gerais State, Brazil, 1,827 people were living on the streets in 2013. This study presents the evaluation of the conditions and perceptions of this population on their rights to water and sanitation access. It has been observed that access to both water and sanitation is precarious and that the normative content, as well as the human rights principles, are highly violated. In conclusion, we observed that this group suffers violations of HRWS and that these are associated with the violation of other rights such as the right to the city, dwelling and health. Such violations have negative impacts on the economic and social life of this group, increasing discrimination and exclusion. This study draws attention to the importance of encouraging the social participation of this group in the decision-making processes of water and sanitation management within the framework of HRWS, in its capacity to be a tool for social transformation, generating empowerment, promoting health, dignity and citizenship. PMID- 29590242 TI - [Sources of medicines for chronic patients using the Brazilian Unified National Health System]. AB - The article aimed to identify the sources of medicines for users of the Brazilian Unified National Health System (SUS) that reported chronic non-communicable diseases, characterizing the group according to demographic, socioeconomic, and health variables in the different regions of Brazil. Data were analyzed from the National Survey on Access, Use, and Promotion of Rational Use of Medicines in Brazil (PNAUM), a cross-sectional population-based study. The dependent variable was "source of medicines", and the associations were analyzed with demographic, socioeconomic, and health status variables. Users that obtained care and medicines solely in the SUS were designated here as SUS-exclusive. Some 39% of persons obtained their medicines from SUS pharmacies and 28.5% from other sources. The study found 42.9%, 41.8%, 40.2%, and 31% of exclusive SUS users in the Southeast, South, North, and Northeast regions of Brazil, respectively. SUS users have the SUS as their primary source of medicines, but there is also a relevant share from other sources, suggesting problems with access in the SUS. In the South and Southeast regions, the population relies less on private pharmacies than in the Northeast and North. PMID- 29590243 TI - [The concept of vulnerability and its meanings for public policies in health and social welfare]. AB - Are concepts of vulnerability capable of influencing social practices and citizenship in the fields of health and social welfare? The article critically assesses this question through a comprehensive-interpretative approach to hermeneutics-dialectics and a review of the literature produced on the theme in the last two decades. There is no vast theoretical output on the theme. However, although conceptually imprecise, the term "vulnerability" expands the understanding of the multiple factors that weaken subjects in the exercise of their citizenship. Professional action in the sphere of health and social welfare policies and the social imaginary are forged by the incorporation of concepts that can either reduce or reinforce vulnerabilities. PMID- 29590244 TI - [A nonlinear model for localization of hospital services as an indicator of accessibility]. AB - The study proposes a differentiated approach to the localization of public services (unlike methods focusing solely on locational efficiency in the distribution of such services), with a nonlinear model that incorporates an accessibility indicator and allows rejecting solutions in which accessibility fails to comply with acceptably established minimum parameters. The method aims to minimize the total time spent by a region's population to reach a public services network, while controlling the range between the highest and lowest accessibility to the services. The resulting solution is not as efficient as other models (e.g., p-median) in relation to total cost for the population as a whole to access the system, but it seeks to prevent the most distant areas from experiencing greater difficulty due to their disproportional traveling time. The model was tested in a region in the hospital network of the State of Santa Catarina, Brazil, and the results show that incorporation of the indicator suggests improvement when compared to the current distribution of hospitals in that area. The proposed methodology can be a useful tool for planning balanced resource allocation during installation of health services for the population.

PMID- 29590246 TI - Carotid intima-media thickness in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil): a narrative review. AB - BACKGROUND: Carotid intima-media thickness (CIMT), as measured by ultrasound, has been used in large studies as a non-invasive marker for subclinical atherosclerosis. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a cohort of 15,105 civil servants in six Brazilian cities that included CIMT evaluation in its baseline assessment. The aim of the present narrative review was to provide an overview of ELSA-Brasil CIMT articles published up to July 31, 2017. DESIGN AND SETTING: Narrative review of ELSA-Brasil CIMT studies using baseline assessment data. METHODS: We searched PubMed for the terms "ELSA-Brasil" and "intima-media". This search yielded 21 published articles using CIMT data from the ELSA-Brasil baseline assessment, which were included in this review. We also present information about intima-media thickness assessment from ongoing onsite reevaluations of the study participants. RESULTS: Most published studies focused on the association with traditional and novel cardiovascular risk factors. Studies also presented information about the ELSA-Brasil CIMT protocol at baseline and CIMT value distribution in this large sample. CONCLUSIONS: Analyses on the ELSA-Brasil data led to important insights on CIMT interpretation and physiology. Besides the highlighted contributions which have already been made in this field, new data gathered during the ongoing third onsite assessment will enable investigation of substantially new research questions.

PMID- 29590247 TI - What do Cochrane systematic reviews say about non-surgical interventions for urinary incontinence in women? AB - BACKGROUND: Urinary incontinence is a highly prevalent condition that impacts self-esteem and overall quality of life. Many non-surgical treatment options are available, ranging from pharmacological approaches to pelvic exercises. We aimed to summarize the available evidence regarding these non-surgical interventions. DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de Sao Paulo (EPM-UNIFESP). METHODS: A sensitive search was conducted to identify all Cochrane systematic reviews that fulfilled the inclusion criteria. Titles and abstracts were screened by two authors. RESULTS: We included 20 Cochrane systematic reviews: 4 assessing methods of vesical training, 3 evaluating pharmacological interventions, 4 studying pelvic floor muscle training approaches and 9 aimed at other alternatives (such as urethral injections, weighted vaginal cone use, acupuncture, biostimulation and radiofrequency therapy). The reviews found that the evidence regarding the benefits of these diverse interventions ranged in quality from low to high. CONCLUSIONS: This review included 20 Cochrane systematic reviews that provided evidence (of diverse quality) for non pharmacological interventions for patients with urinary incontinence. Moderate to high quality of evidence was found favoring the use of pelvic floor muscle training among women with urinary incontinence. To establish solid conclusions for all the other comparisons, further studies of good methodological quality are needed. PMID- 29590249 TI - Quantitative and qualitative variables of semen from surubim do Iguacu, Steindachneridion melanodermatum Garavello, 2005 (Siluriformes: Pimelodidae). AB - The objective of the present work was to assess the qualitative and quantitative characteristics of semen from the surubim do Iguacu (Steindachneridion melanodermatum). Induced spermiation was achieved in eleven males with mean weight of 1.76 +/- 0.48 kg and average age of two years and semen was collected by stripping. The average volume was 1.34 +/- 0.73 mL. The duration of sperm motility was 154.4 +/- 72.6 and 149.0 +/- 77.5 seconds after activation with hatchery water and distilled water, respectively. The sperm concentration estimated by hemocytometer was 5.423 +/- 2.155 x 1010 spermatozoa/mL. The results indicate that S. melanodermatum semen is easily obtained during the spawning season and the seminal characteristics are adequate insemination and subsequent in vitro fertilization. PMID- 29590250 TI - Thrips species (Insecta: Thysanoptera) associated with flowers in a restinga fragment in northeastern Brazil. AB - With the growing volume of research involving Thysanoptera in Brazil, studies were carried out to improve our understanding of the diversity of thrips in areas where the fauna has historically been neglected. Accordingly, we recorded the diversity of thrips (Insecta: Thysanoptera) associated with a restinga fragment located on the campus of the State University of Ceara (UECE), Fortaleza, Ceara state, and computed the estimated richness and diversity indices. Samples were collected from 2011 through 2013 from flowers of 86 plant species. The material was taken to the Laboratory of Insect-Plant Interaction, where thrips were screened under stereomicroscope. We collected 456 adults and 58 immatures, representing 14 species, in addition to one unidentified species of Treherniella. Microcephalothrips abdominalis was found on a large number of host plants, and Frankliniella insularis was the most common species. About two-thirds of the total richness of thrips species was associated with three plant families (Amaranthaceae, Caesalpiniaceae and Poaceae); six thrips species were each associated with only one plant species. The richness of the species collected was close to that estimated by Bootstrap and Jackknife 1 analysis. The Shannon-Wiener (H') and Simpson (D) diversity indexes were 1,7607 and 0.7769, respectively. Although the species are common, 46 new associations between plant species and thrips were established, 13 of which are true host associations, which demonstrates the importance of coastal vegetation in maintaining populations of thrips. PMID- 29590251 TI - Responses of antioxidant enzymes, photosynthetic pigments and carbohydrates in micropropagated Pitcairnia encholirioides L.B. Sm. (Bromeliaceae) under ex vitro water deficit and after rehydration. AB - In this study, the activities of antioxidant enzymes, photosynthetic pigments, proline and carbohydrate contents in Pitcairnia encholirioides under ex vitro conditions of water deficit were evaluated. Results show that plants under progressive water stress, previously in vitro cultured in media supplemented with 30 g L-1 sucrose and GA3, accumulated more proline and increased peroxidase (POD) activity and the contents of photosynthetic pigments and carbohydrates. For plants previously in vitro cultured with 15 g L-1 sucrose and NAA, no differences were found for proline content and there were reductions in activities of peroxidase (POD), catalase (CAT) and poliphenoloxidase (PPO), and in contents of carbohydrates, with progress of ex vitro water deficit. After rehydration, plants showed physiological recovery, with enzymatic activities and contents of metabolites similar to those found in the controls not submitted to dehydration, regardless of the previous in vitro culture conditions. These results show that micropropagated P. encholirioides has high tolerance to dehydration once in ex vitro conditions, which can ensure the survival of plants from tissue culture when transferred to its natural environment, emphasizing the importance of such biotechnology for the propagation of endangered species. PMID- 29590252 TI - Morphology of the spermatheca of Triatoma lecticularia (Hemiptera: Reduviidae) (Stal, 1859). AB - Triatoma lecticularia (Hemiptera: Reduviidae) (Stal, 1859) is a potential vector of Chagas's disease and the comprehension of its reproductive biology is an important tool to control this insect. In the reproductive tract of female insects, the spermatheca plays a crucial role storing male spermatozoa after mating. Whithin insects the spermatheca shows a wide morphological diversity and the analysis of this characteristic can contribute to understand the reproductive biology of the species. This study describes the histology and histochemistry of the spermatheca of T. lecticularia. Females have a pair of elongated spermathecal reservoirs without associated accessory gland. The reservoir opens into the common oviduct via a narrow muscular duct. The reservoir epithelium has single layer of columnar secretory cells. The control of the release of spermatozoa from the spermatheca occurs via the muscular duct. The anatomical features of the spermatheca of T. lecticularia resemble those described of other Reduviidae. However, the histological and histochemical features of spermatheca observed in T. lecticularia were important to explain the maintenance of the viability of the spermatozoa stored.

AB - Reactive oxygen species and lipid peroxidation are important factors that contribute to the development of age-related cataract. The study included 130 patients with age-related cataract, 69 of whom were diagnosed with hypertension (HT), 20 with hypertension and type 2 diabetes mellitus (DM), and 41 had no accompanying condition. The following parameters were measured in the serum of the examinees: products of lipid peroxidation malondialdehyde (MDA) and lipofuscin-like fluorophores (LLF), activity of prooxidative enzymes xanthine oxidase (XO) and myeloperoxidase (MPO), antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx), the concentration of thiol groups, and the ferric reducing activity of plasma. The activity of prooxidative enzymes XO and MPO was higher in the plasma of patients with HT (XO=9.0+/-1.2 U/L; MPO=77.3+/-8.4 U/L) and with HT and DM (XO=11.9+/-0.9 U/L; MPO=89.5+/-5.0 U/L) compared to patients with age-related cataract (XO=6.2+/-0.9 U/L; MPO=52.4+/-6.3 U/L; P<0.01). Our research has shown that patients with age-related cataract and hypertension were exposed to increased oxidative damage of biomolecules, based on the increased plasma LLF and MDA content and decreased levels of thiol groups. Oxidative changes of biomolecules in these patients were associated with increased activity of the XO, MPO, and GPx enzymes and a lower extracellular SOD activity and total ferric reductive ability of plasma. PMID- 29590255 TI - Use of cardiopulmonary exercise testing to assess early ventilatory changes related to occupational particulate matter. AB - Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive enough to show abnormalities before extensive damage, as seen in restrictive lung diseases. Therefore, we hypothesized that cardiopulmonary exercise testing (CPET) may be better than spirometry to detect early ventilatory impairment caused by OEPM. We selected 135 male workers with at least one year of exposure. After collection of self-reported socioeconomic status, educational level, and cardiovascular risk data, participants underwent spirometry, CPET, body composition assessment (bioelectrical impedance), and triaxial accelerometry (for level of physical activity in daily life). CPET was performed using a ramp protocol on a treadmill. Metabolic, cardiovascular, ventilatory, and submaximal relationships were measured. We compared 52 exposed to 83 non-exposed workers. Multiple linear regressions were developed using spirometry and CPET variables as outcomes and OEPM as the main predictor, and adjusted by the main covariates. Our results showed that OEPM was associated with significant reductions in peak minute ventilation, peak tidal volume, and breathing reserve index. Exposed participants presented shallower slope of DeltaVT/DeltalnVE (breathing pattern), i.e., increased tachypneic breathing pattern. The OEPM explained 7.4% of the DeltaVT/DeltalnVE variability. We found no significant influence of spirometric indices after multiple linear regressions. We conclude that CPET might be a more sensitive feature of assessing early pulmonary impairment related to OEPM. Our cross-sectional results suggested that CPET is a promising tool for the screening of asymptomatic male workers. PMID- 29590256 TI - Unsteady walking as a symptom in type 2 diabetes mellitus: independent association with depression and sedentary lifestyle and no association with diabetic neuropathy. AB - The purpose of this study was to look at the determinants of the unsteady walking (UW) symptom in patients with type 2 diabetes mellitus (T2DM) by defining if UW and/or the Diabetic Neuropathy Symptoms Score (DNSS) are associated with positive scores in Beck's Depression Inventory (BDI) and with a positive Michigan Neuropathy Screening Instrument score (MNSI). We evaluated 203 T2DM patients without visible gait disturbances. They were divided into UW (+) and UW (-) or DNSS (+) and DNSS (-) according to symptoms. We found a prevalence of 48.3% for UW (+) and of 63% for DNSS (+) in our sample. In univariate analysis, the presence of UW was significantly associated with waist circumference (P=0.024), number of comorbidities (P=0.012), not practicing physical exercise (P=0.011), positive BDI score (P=0.003), presence of neuropathic symptoms by the MNSI questionnaire (P<0.001), and positive diabetic neuropathy screening by MNSI (P=0.021). In multivariate analysis, UW (used as a dependent variable) was independently associated with a positive BDI score (P<0.001; 95%CI=1.01-1.03), T2DM duration (P=0.023; 95%CI=1.00-1.03), number of co-morbidities (P=0.032; 95%CI=1.01-1.37), and a sedentary lifestyle (P=0.025; 95%CI=1.06-2.5). The UW symptom and a positive DNSS are more closely related to a positive score for depression than to presence of neuropathy in T2DM. PMID- 29590257 TI - Renovascular hypertension increases serum TNF and CX3CL1 in experimental Trypanosoma cruzi infection. AB - Trypanosoma cruzi triggers a progressive inflammatory response affecting cardiovascular functions in humans and experimental models. Angiotensin II, a key effector of the renin-angiotensin system, plays roles in mediating hypertension, heart failure, and inflammatory responses. T. cruzi and AngII can induce inflammatory responses by releasing inflammatory mediators. The aim of this study was to evaluate systemic AngII, tumor necrosis factor (TNF), and CX3CL1 mediators in a two-kidney one-clip (2K1C) renovascular hypertension model using Wistar rats infected with T. cruzi. Our data showed an increase in serum AngII in uninfected and T. cruzi-infected rats 1 week after 2K1C surgery compared to non-2K1C (Sham) animals. The baseline systolic blood pressure was higher in both uninfected and infected 2K1C rats. Despite no difference in circulating parasites in the acute phase of infection, elevated serum TNF and CX3CL1 were observed at 8 weeks post infection in 2K1C rats in association with higher cardiac inflammatory infiltration. In summary, AngII-induced hypertension associated with T. cruzi infection may act synergistically to increase TNF and CX3CL1 in the 2K1C rat model, thereby intensifying cardiac inflammatory infiltration and worsening the underlying inflammation triggered by this protozoan. PMID- 29590258 TI - Human dental pulp stem cell adhesion and detachment in polycaprolactone electrospun scaffolds under direct perfusion. AB - Cell adhesion in three-dimensional scaffolds plays a key role in tissue development. However, stem cell behavior in electrospun scaffolds under perfusion is not fully understood. Thus, an investigation was made on the effect of flow rate and shear stress, adhesion time, and seeding density under direct perfusion in polycaprolactone electrospun scaffolds on human dental pulp stem cell detachment. Polycaprolactone scaffolds were electrospun using a solvent mixture of chloroform and methanol. The viable cell number was determined at each tested condition. Cell morphology was analyzed by confocal microscopy after various incubation times for static cell adhesion with a high seeding density. Scanning electron microscopy images were obtained before and after perfusion for the highest flow rate tested. The wall pore shear stress was calculated for all tested flow rates (0.005-3 mL/min). An inversely proportional relationship between adhesion time with cell detachment under perfusion was observed. Lower flow rates and lower seeding densities reduced the drag of cells by shear stress. However, there was an operational limit for the lowest flow rate that can be used without compromising cell viability, indicating that a flow rate of 0.05 mL/min might be more suitable for the tested cell culture in electrospun scaffolds under direct perfusion. PMID- 29590259 TI - Individual variation is the key to the development of a vaccine against Staphylococcus aureus: a comparative study between mice lineages. AB - Bacterial infections occur worldwide and are a major public health problem. Among pathogens, Staphylococcus aureus is the main causative agent of bacterial diseases in the world. This study aimed to evaluate which components of the immune system could act protectively against a S. aureus infection in intradermally immunized mice. C57BL/6 and A/j mice were immunized intradermally with S. aureus inactivated by heat and then challenged with viable strains in an air pouch model. At 6, 12, and 24 h after the challenge, euthanasia was performed, and the cellular profile of the inflammatory infiltrate, cytokines, and the bacterial load were evaluated in the air pouch lavages. Immunized mice demonstrated that the intradermal immunization with S. aureus promoted protection in C57BL/6 mice by reducing the bacterial, which was correlated with increased serum concentration of IgG antibodies (IgG1 and IgG2a) against S. aureus. The increase in IgG2a antibody levels was correlated with a decrease of bacterial load in intradermally immunized C57BL/6 mice, along with production of IL-17A at the inflammation site, as well as IgG1consumption. Similar results were not found in the A/j lineage. In conclusion, a vaccine against S. aureus should focus more on the individual characteristics of the host because it is a determinant factor for the success of the immunization. PMID- 29590260 TI - Effect of pre-exercise carbohydrate availability on fat oxidation and energy expenditure after a high-intensity exercise. AB - The aim of this study was to test the hypothesis that reduced pre-exercise carbohydrate (CHO) availability potentiates fat oxidation after an exhaustive high-intensity exercise bout. Eight physically active men underwent a high intensity exercise (~95% VO2max) until exhaustion under low or high pre-exercise CHO availability. The protocol to manipulate pre-exercise CHO availability consisted of a 90-min cycling bout at ~70% VO2max + 6 * 1-min at 125% VO2max with 1-min rest, followed by 48 h under a low- (10% CHO, low-CHO availability) or high CHO diet (80% CHO, high-CHO availability). Time to exhaustion was shorter and energy expenditure (EE) lower during the high-intensity exercise in low- compared to high-CHO availability (8.6+/-0.8 and 11.4+/-1.6 min, and 499+/-209 and 677+/ 343 kJ, respectively, P<0.05). Post-exercise EE was similar between low- and high CHO availability (425+/-147 and 348+/-54 kJ, respectively, P>0.05), but post exercise fat oxidation was significantly higher (P<0.05) in low- (7,830+/-1,864 mg) than in high-CHO availability (6,264+/-1,763 mg). The total EE (i.e., exercise EE plus post-exercise EE) was similar between low- and high-CHO availability (924+/-264 and 1,026+/-340 kJ, respectively, P>0.05). These results suggest that a single bout of high-intensity exercise performed under low-CHO availability increased post-exercise fat oxidation, and even with shorter exercise duration, both post-exercise EE and total EE were not impaired. PMID- 29590261 TI - Performance during a strenuous swimming session is associated with high blood lactate: pyruvate ratio and hypoglycemia in fasted rats. AB - The aim of this study was to investigate the effect of lactatemia elevation and glycemia reduction on strenuous swimming performance in fasted rats. Three rats were placed in a swimming tank at the same time. The first rat was removed immediately (control group) and the remaining ones were submitted to a strenuous swimming session. After the second rat was exhausted (Exh group), the third one was immediately removed from the water (Exe group). According to the period of time required for exhaustion, the rats were divided into four groups: low performance (3-7 min), low-intermediary performance (8-12 min), high-intermediary performance (13-17 min), and high performance (18-22 min). All rats were removed from the swimming tanks and immediately killed by decapitation for blood collection or anesthetized for liver perfusion experiments. Blood glucose, lactate, and pyruvate concentrations, blood lactate/pyruvate ratio, and liver lactate uptake and its conversion to glucose were evaluated. Exhaustion in low and low-intermediary performance were better associated with higher lactate/pyruvate ratio. On the other hand, exhaustion in high-intermediary and high performance was better associated with hypoglycemia. Lactate uptake and glucose production from lactate in livers from the Exe and Exh groups were maintained. We concluded that there is a time sequence in the participation of lactate/pyruvate ratio and hypoglycemia in performance during an acute strenuous swimming section in fasted rats. The liver had an important participation in preventing hyperlactatemia and hypoglycemia during swimming through lactate uptake and its conversion to glucose. PMID- 29590263 TI - Cognitive-behavioral group therapy for intermittent explosive disorder: description and preliminary analysis. AB - OBJECTIVES: To evaluate the efficacy of a group therapy based on cognitive behavioral techniques customized for intermittent explosive disorder (IED). The current report presents the preliminary results of a clinical trial comparing pre and post-intervention scores in different anger dimensions. METHODS: The studied sample consisted of 84 treatment-seeking subjects. The mean (standard deviation) age was 43.0 (11.9) years, and 78% were male. The therapeutic group program consisted of 15 weekly sessions plus three maintenance sessions. The sessions lasted approximately 90 minutes each. RESULTS: No differences were found in demographic profile and pre-treatment status between subjects who completed treatment (n=59) and dropouts (n=25). Comparison of State-Trait Anger Expression Scale (STAXI) scores pre- and post-treatment showed statistically significant changes in all anger scales and subscales of the questionnaire. CONCLUSION: This preliminary report is a significant addition to currently scarce clinical data. Our findings provide further evidence that structured cognitive-behavioral group therapy, with a focus on anger management and cognitive coping, may be a promising approach to the treatment of IED. PMID- 29590262 TI - PCR-RFLP assay as an option for primary HPV test. AB - Persistent human papillomavirus (HPV) infection is an essential factor of cervical cancer. This study evaluated the analytical performance of restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) assay compared to PapilloCheck(r) microarray to identify human papilloma virus (HPV) in cervical cells. Three hundred and twenty-five women were analyzed. One sample was used for conventional cytology and another sample was collected using BD SurePathTM kit for HPV tests. Eighty samples (24.6%) were positive for HPV gene by PCR-Multiplex and were then submitted to PCR-RFLP and PapilloCheck(r) microarray. There was a genotyping agreement in 71.25% (57/80) on at least one HPV type between PCR-RFLP and PapilloCheck(r) microarray. In 22 samples (27.5%), the results were discordant and those samples were additionally analyzed by DNA sequencing. HPV 16 was the most prevalent HPV type found in both methods, followed by HPVs 53, 68, 18, 39, and 66 using PCR-RFLP analysis, and HPVs 39, 53, 68, 56, 31, and 66 using PapilloCheck(r) microarray. In the present study, a perfect agreement using Cohen's kappa (kappa) was found in HPV 33 and 58 (kappa=1), very good for HPV 51, and good for types 16, 18, 53, 59, 66, 68, 70, and 73. PCR-RFLP analysis identified only 25% (20/80) HPV coinfection, and PapilloCheck(r) microarray found 62.5% (50/80). Our Cohen's kappa results indicate that our in-house HPV genotyping testing (PCR-RFLP analysis) could be applied as a primary HPV test screening, especially in low income countries. If multiple HPV types are found in this primary test, a more descriptive test, such as PapilloCheck(r) microarray, could be performed.

AB - OBJECTIVE: To test the psychometric properties of the EUROHIS-QOL 8-item index in a Brazilian sample. METHODS: The sample consisted of 151 patients and 174 healthy controls (n=325). Several psychometric properties were tested. RESULTS: Reliability showed good internal consistency (Cronbach's alpha = 0.81). The measure showed good discriminant validity between patients and healthy controls (mean1 = 3.32, SD1 = 0.70; mean2 = 3.77, SD2 = 0.63, t = 6.12, p < 0.001). Convergent validity showed significant correlations (p < 0.001) between the EUROHIS-QOL 8-item index and all domains of the WHOQOL-Bref (overall r = 0.47; general health r = 0.54; physical r = 0.69; psychological r = 0.62; social relationship r = 0.55; environment r = 0.55) and between the EUROHIS-QOL 8-item index and the domains of the SF-36, except for the social domain (p = 0.38). On Rasch analysis of unidimensionality, general fit measures showed adequate performance. The EUROHIS-QOL 8-item index also showed good fit on confirmatory factor analysis (CFA) (chi-square = 18.46, degrees of freedom [df] = 15; comparative fit index [CFI] = 0.99; root mean square error of approximation [RMSEA] = 0.03; goodness of fit index [gfi] = 0.99; root mean square residual [RMR] = 0.03; p = 24). CONCLUSION: The EUROHIS-QOL 8-item index showed good psychometric properties. It is a reliable quality of life measure that can be used in Brazilian populations. PMID- 29590265 TI - The association between social skills deficits and family history of mood disorder in bipolar I disorder. AB - OBJECTIVE: To compare social skills and related executive functions among bipolar disorder (BD) patients with a family history of mood disorders (FHMD), BD patients with no FHMD and healthy control (HCs). METHODS: We evaluated 20 euthymic patients with FHMD, 17 euthymic patients without FHMD, and 31 HCs using the Social Skills Inventory (SSI) and a neuropsychological battery evaluating executive function, inhibitory control, verbal fluency and estimated intelligence. RESULTS: Both BD groups had lower SSI scores than controls. Scores for one subfactor of the social skills questionnaire, conversational skills and social performance, were significantly lower among patients with FHMD than among patients without FHMD (p = 0.019). Both groups of BD patients exhibited significant deficits in initiation/inhibition, but only BD patients with FHMD had deficits in verbal fluency, both compared to HC. There were no associations between social skills questionnaire scores and measures of cognitive function. CONCLUSION: Euthymic BD patients have lower social skills and executive function performance than HC. The presence of FHMD among BD patients is specifically associated with deficits in conversational and social performance skills, in addition to deficits in verbal fluency. Both characteristics might be associated with a common genetically determined pathophysiological substrate.

AB - Dietary protein may help prevent age-related declines in strength and functional capacity. This study examines the independent relationship between dietary protein and longitudinal changes in physical functioning among adults participating in the Framingham Offspring Study from examination 5 (1991-1995) to examination 8 (2005-2008). Protein intakes were derived from 3-day diet records during examinations 3 and 5; functional status was determined over 12 years using 7 items selected from standardized questionnaires. Multivariable models adjusted for age, sex, education, physical activity, smoking, height, and energy intake. Functional tasks that benefitted most from a higher-protein diet (>=1.2 g/kg/day vs. <0.8 g/kg/day) were doing heavy work at home, walking 1/2 mile (0.8 km), going up and down stairs, stooping/kneeling/crouching, and lifting heavy items. Those with higher protein intakes were 41% less likely (95% CI: 0.43, 0.82) to become dependent in 1 or more of the functional tasks over follow-up. Higher physical activity and lower body mass index were both independently associated with less functional decline. The greatest risk reductions were found among those with higher protein intakes combined with either higher physical activity, more skeletal muscle mass, or lower body mass index. This study demonstrates that dietary protein intakes above the current US Recommended Daily Allowance may slow functional decline in older adults.

AB - Importance: Patients with psoriasis enrolled in clinical trials of biologics may not be representative of the real-world population. There is evidence that patients ineligible for such trials have a greater risk of serious adverse events (SAEs), but the effect on drug discontinuation and effectiveness are unknown. Objective: To determine whether (1) drug discontinuation, (2) effectiveness, and (3) rates of SAEs differ in patients with psoriasis categorized as eligible or ineligible for clinical trials. Design, Setting, and Participants: An observational study using 157 dermatology centers in the United Kingdom and Republic of Ireland was carried out wherein we applied the eligibility criteria of clinical trials of biologic therapies for psoriasis to patients who were being followed up in the British Association of Dermatologists Biologic Interventions Register (BADBIR) and being prescribed biologics as part of standard clinical care. Patients with psoriasis registered to BADBIR who were taking etanercept (enbrel only; n = 1509), adalimumab (n = 4000), and ustekinumab (n = 1627) with at least 1 follow-up visit. Eligibility criteria were extracted from phase 3 licensing trials for etanercept, adalimumab, and ustekinumab for the treatment of moderate to severe psoriasis. Patients in BADBIR with a missing baseline Psoriasis Area and Severity Index (PASI) or baseline PASI value less than 10 (etanercept) or less than 12 (adalimumab; ustekinumab) but who would otherwise be eligible were investigated separately. Eligibility categories applied to BADBIR included: eligible, ineligible, insufficient baseline PASI only, and missing baseline PASI only. Main Outcomes and Measures: (1) Drug discontinuation: cumulative incidence at 12 months by stop reason per eligibility category and drug; (2) effectiveness: linear regression of absolute change in PASI from baseline to 6 and 12 months; and (3) SAEs: incidence rate ratio (IRR) at 12 months between eligibility categories per drug. Results: The mean (SD) age of the 7136 patients included in the analysis was 45 (13) years and 2924 (41%) were women and 4212 (59%) were men. Of 7136 patients, 839 (56%) etanercept, 2219 (56%) adalimumab, and 754 (46%) ustekinumab registrations were categorized as eligible. The most common reasons for ineligibility were diabetes (etanercept, 143 [9%]; ustekinumab, 201 [12%]) and nonchronic plaque psoriasis (adalimumab, 157 [4%]). Patients categorized as ineligible (etanercept, 367 [24%]; adalimumab, 282 [7%]; ustekinumab, 394 [24%]) achieved a smaller absolute change in PASI after 6 and 12 months (adalimumab, ustekinumab), and had significantly higher rates of SAEs compared with the eligible category (etanercept: IRR, 1.9; 95% CI, 1.4-2.6; adalimumab: IRR, 2.0; 95% CI, 1.5-2.6; ustekinumab: IRR, 2.8; 95% CI, 2.1-3.8). No significant differences in drug discontinuation were observed between categories. Conclusions and Relevance: Clinical trial effectiveness and safety outcomes are not representative of real-world patients in BADBIR patients categorized as ineligible for such trials. PMID- 29590280 TI - The Emerging Clinical Neuroscience of Autism Spectrum Disorder: A Review. AB - Importance: Autism spectrum disorder (ASD) is a highly prevalent disorder, and community psychiatrists are likely to treat many individuals with ASD during their clinical practice. This clinical case challenge describes a routine evaluation of irritability and self-injury in a preschool-aged child who meets the criteria for ASD. The case also illustrates the importance of known risk factors for ASD, such as chromosomal deletion and prematurity. This clinical neuroscience article seeks to educate the clinician of current avenues of research that can inform and may already affect clinical practice for this patient, while providing a preview of research that may yield biological treatments for ASD within the next decade. Observations: A diagnosis of ASD is defined behaviorally; therefore, many genetic and environmental risk factors, working singly or in concert, are linked to ASD. The prenatal period of brain development is particularly sensitive to risk factors such as gene mutation or drug exposure that affect brain development and circuitry formation. Currently, neuroimaging researchers can detect changes in brain connectivity of children with ASD as young as 6 months, followed by an atypical trajectory of brain development through preschool age and ongoing connectivity inefficiencies across the lifespan. Animal and cellular model systems have provided a means for defining the molecular and cellular changes associated with risk factors for ASD. The ability to connect specific treatments to particular subgroups of people with ASD is the defining hope of precision medicine initiatives. Conclusions and Relevance: The advent of next-generation sequencing technology, advanced imaging techniques, and cutting-edge molecular techniques for modeling ASD has allowed researchers to define ASD risk-related biological pathways and circuits that may, for the first time, unify the effects of disparate risk factors into common neurobiological mechanisms. The path from these mechanisms to biological treatments that improve the lives of individuals with autism remains unclear, but the cumulative output of multiple lines of research suggests that subtyping by genetic risk factors may be a particularly tractable way to capitalize on individual differences amenable to specific treatments.

PMID- 29590281 TI - Association of Childhood Irritability and Depressive/Anxious Mood Profiles With Adolescent Suicidal Ideation and Attempts. AB - Importance: Suicidal ideation and suicide attempt (suicidality) are common in adolescence and a public health concern. Childhood depression is a key risk factor for later suicidality and often co-occurs with irritability. No study to date has examined the joint association of depressive mood and irritability during childhood with later suicidality. Objective: To investigate the association of childhood irritability and depressive/anxious mood profiles with adolescent suicidality. Design, Setting, and Participants: This population-based cohort study included 1430 participants in the Quebec Longitudinal Study of Child Development. Participants underwent assessment yearly or bi-yearly (5 months to 17 years). Data were collected from March 16, 1998, through July 17, 2015. Exposures: Profiles defined by the joint developmental trajectories of irritability and depressive/anxious mood at 6 to 12 years of age. Main Outcomes and Measures: Self-reported past-year suicidality (ie, serious suicidal ideation or suicide attempt) at 13, 15, and 17 years of age. Irritability and depressive/anxious mood were assessed using teacher report 5 times from 6 to 12 years of age. Results: The study included 1430 participants (676 boys [47.3%] and 754 girls [52.7%]) followed up to 17 years of age. Group-based multitrajectory modeling identified the following profiles: combined no irritability and low depressive/anxious mood with low irritability and low depressive/anxious mood (831 [58.1%]; reference group), moderate irritability and low depressive/anxious mood (353 [24.7%]), high depressive/anxious mood only (94 [6.6%]), and high irritability and depressive/anxious mood (152 [10.6%]). Children with high irritability and high depressive/anxious mood reported higher rates of suicidality (25 of 152 [16.4%]) compared with the group with the lowest symptom levels (91 of 831 [11.0%]). In logistic regression analyses, the high irritability and depressive/anxious mood profile (odds ratio [OR], 2.22; 95% CI, 1.32-3.74; number needed to be exposed [NNE], 18) was associated with suicidality. To a lesser extent, the moderate irritability and low depressive/anxious mood profile was also associated with suicidality (OR, 1.51; 95% CI, 1.02-2.25; NNE = 48). The high depressive/anxious mood only profile was not associated with later suicidality (OR, 0.96; 95% CI, 0.47-1.95; NNE = -320). The high irritability and depressive/anxious mood profile was associated with a higher suicidal risk compared with the depressive/anxious mood only profile (OR, 2.28; 95% CI, 1.02-5.15). Girls with the high irritability and high depressive/anxious mood profile had higher risk for suicidality (OR, 3.07; 95% CI, 1.54-6.12; NNE = 5). Conclusions and Relevance: Children with high irritability and depressive/anxious mood and, to a lesser extent, with moderate irritability only had a higher suicidal risk during adolescence compared with children with low symptom levels. Early manifestation of chronic irritability during childhood, especially when combined with depressive/anxious mood, may be associated with an elevated risk for adolescent suicidality. The putatively causal role of irritability should be investigated.

AB - Importance: Bariatric surgery is a life-changing treatment for patients with severe obesity, but little is known about its association with interpersonal relationships. Objectives: To investigate if relationship status is altered after bariatric surgery. Design, Setting, and Participants: Changes in relationship status after bariatric surgery were examined in 2 cohorts: (1) the prospective Swedish Obese Subjects (SOS) study, which recruited patients undergoing bariatric surgery from September 1, 1987, to January 31, 2001, and compared their care with usual nonsurgical care in matched obese control participants; and (2) participants from the Scandinavian Obesity Surgery Registry (SOReg), a prospective, electronically captured register that recruited patients from January 2007 through December 2012 and selected comparator participants from the general population matched on age, sex, and place of residence. Data was collected in surgical departments and primary health care centers in Sweden. The current analysis includes data collected up until July 2015 (SOS) and December 2012 (SOReg). Data analysis was completed from June 2016 to December 2017. Main Outcomes and Measures: In the SOS study, information on relationship status was obtained from questionnaires. In the SOReg and general population cohort, information on marriage and divorce was obtained from the Swedish Total Population Registry. Results: The SOS study included 1958 patients who had bariatric surgery (of whom 1389 [70.9%] were female) and 1912 matched obese controls (of whom 1354 [70.8%] were female) and had a median (range) follow-up of 10 (0.5-20) years. The SOReg cohort included 29 234 patients who had gastric bypass surgery (of whom 22 131 [75.6%] were female) and 283 748 comparators from the general population (of whom 214 342 [75.5%] were female), and had a median (range) follow-up of 2.9 (0.003-7.0) years. In the SOS study, the surgical patients received gastric banding (n = 368; 18.8%), vertical banded gastroplasty (n = 1331; 68.0%), or gastric bypass (n = 259; 13.2%); controls received usual obesity care. In SOReg, all 29 234 surgical participants received gastric bypass surgery. In the SOS study, bariatric surgery was associated with increased incidence of divorce/separation compared with controls for those in a relationship (adjusted hazard ratio [aHR] = 1.28; 95% CI, 1.03-1.60; P = .03) and increased incidence of marriage or new relationship (aHR = 2.03; 95% CI, 1.52 2.71; P < .001) in those who were unmarried or single at baseline. In the SOReg and general population cohort, gastric bypass was associated with increased incidence of divorce compared with married control participants (aHR = 1.41; 95% CI, 1.33-1.49; P < .001) and increased incidence of marriage in those who were unmarried at baseline (aHR = 1.35; 95% CI, 1.28-1.42; P < .001). Within the surgery groups, changes in relationship status were more common in those with larger weight loss. Conclusions and Relevance: In addition to its association with obesity comorbidities, bariatric surgery-induced weight loss is also associated with changes in relationship status.

PMID- 29590294 TI - Leveraging known genomic variants to improve detection of variants, especially close-by Indels. AB - Motivation: The detection of genomic variants has great significance in genomics, bioinformatics, biomedical research and its applications. However, despite a lot of effort, Indels and structural variants are still under-characterized compared to SNPs. Current approaches based on next-generation sequencing data usually require large numbers of reads (high coverage) to be able to detect such types of variants accurately. However Indels, especially those close to each other, are still hard to detect accurately. Results: We introduce a novel approach that leverages known variant information, e.g. provided by dbSNP, dbVar, ExAC or the 1000 Genomes Project, to improve sensitivity of detecting variants, especially close-by Indels. In our approach, the standard reference genome and the known variants are combined to build a meta-reference, which is expected to be probabilistically closer to the subject genomes than the standard reference. An alignment algorithm, which can take into account known variant information, is developed to accurately align reads to the meta-reference. This strategy resulted in accurate alignment and variant calling even with low coverage data. We showed that compared to popular methods such as GATK and SAMtools, our method significantly improves the sensitivity of detecting variants, especially Indels that are close to each other. In particular, our method was able to call these close-by Indels at a 15-20% higher sensitivity than other methods at low coverage, and still get 1-5% higher sensitivity at high coverage, at competitive precision. These results were validated using simulated data with variant profiles extracted from the 1000 Genomes Project data, and real data from the Illumina Platinum Genomes Project and ExAC database. Our finding suggests that by incorporating known variant information in an appropriate manner, sensitive variant calling is possible at a low cost.

AB - Motivation: Annotation of genomic variants is an increasingly important and complex part of the analysis of sequence-based genomic analyses. Computational predictions of variant function are routinely incorporated into gene-based analyses of rare-variants, though to date most studies use limited information for assessing variant function that is often agnostic of the disease being studied. Results: In this work, we outline an annotation process motivated by the Alzheimer's Disease Sequencing Project, illustrate the impact of including tissue specific transcript sets and sources of gene regulatory information and assess the potential impact of changing genomic builds on the annotation process. While these factors only impact a small proportion of total variant annotations (~5%), they influence the potential analysis of a large fraction of genes (~25%). Availability and implementation: Individual variant annotations are available via the NIAGADS GenomicsDB, at https://www.niagads.org/genomics/ tools-and software/databases/genomics-database.

PMID- 29590297 TI - Deep learning improves antimicrobial peptide recognition. AB - Motivation: Bacterial resistance to antibiotics is a growing concern. Antimicrobial peptides (AMPs), natural components of innate immunity, are popular targets for developing new drugs. Machine learning methods are now commonly adopted by wet-laboratory researchers to screen for promising candidates. Results: In this work, we utilize deep learning to recognize antimicrobial activity. We propose a neural network model with convolutional and recurrent layers that leverage primary sequence composition. Results show that the proposed model outperforms state-of-the-art classification models on a comprehensive dataset. By utilizing the embedding weights, we also present a reduced-alphabet representation and show that reasonable AMP recognition can be maintained using nine amino acid types.

PMID- 29590300 TI - Amyotrophic lateral sclerosis and exposure to diesel exhaust in a Danish cohort. AB - Previous studies have suggested an increased risk of amyotrophic lateral sclerosis (ALS) and other motor neuron diseases for those in occupations commonly exposed to diesel exhaust (DE). In this study, we investigated the association between occupational exposures to DE and odds of ALS. ALS cases were identified from the Danish National Patient Registry 1982 to 2013 and individually matched to 100 controls per case based on birth year and sex. Using occupational history since 1964 from the Danish Pension Fund, Cumulative DE exposures were estimated using a job exposure matrix. Associations were evaluated using conditional logistic regression analyses and stratified by sex. DE exposure at 10-year lag periods was positively associated with ALS in men ever exposed (aOR: 1.20; 95% CI: 1.05, 1.38). For men with > 50% probability of DE exposure, we observed a positive association with ALS and the highest quartile exposures during the 5 year lag period (aOR: 1.40; 95% CI: 1.11, 1.78) and 10-year lag period (aOR: 1.41; 95% CI: 1.11, 1.79). Our study suggests an association between consistently higher exposures to DE and ALS in men but not in women. These findings support those of previously reported associations between ALS and commonly DE exposed occupations. PMID- 29590301 TI - GENEASE: real time bioinformatics tool for multi-omics and disease ontology exploration, analysis and visualization. AB - Motivation: Advances in high-throughput sequencing technologies have made it possible to generate multiple omics data at an unprecedented rate and scale. The accumulation of these omics data far outpaces the rate at which biologists can mine and generate new hypothesis to test experimentally. There is an urgent need to develop a myriad of powerful tools to efficiently and effectively search and filter these resources to address specific post-GWAS functional genomics questions. However, to date, these resources are scattered across several databases and often lack a unified portal for data annotation and analytics. In addition, existing tools to analyze and visualize these databases are highly fragmented, resulting researchers to access multiple applications and manual interventions for each gene or variant in an ad hoc fashion until all the questions are answered. Results: In this study, we present GENEASE, a web-based one-stop bioinformatics tool designed to not only query and explore multi-omics and phenotype databases (e.g. GTEx, ClinVar, dbGaP, GWAS Catalog, ENCODE, Roadmap Epigenomics, KEGG, Reactome, Gene and Phenotype Ontology) in a single web interface but also to perform seamless post genome-wide association downstream functional and overlap analysis for non-coding regulatory variants. GENEASE accesses over 50 different databases in public domain including model organism specific databases to facilitate gene/variant and disease exploration, enrichment and overlap analysis in real time. It is a user-friendly tool with point-and click interface containing links for support information including user manual and examples.

AB - Preterm birth accounts for the majority of neonatal morbidity and mortality in the developed world. A significant proportion of cases of spontaneous preterm labor are attributable to infections within gestational tissues. Surfactant protein A (SP-A), a collectin produced in the fetal lung and other tissues, has been shown previously in mice to suppress preterm delivery due to intrauterine (IU) instillation of sterile proinflammatory substances. Here we report a powerful antilabor effect for SP-A after IU infection with live Escherichia coli. SP-A abolished preterm birth (rate reduced from 100% to 0%) when it was administered into the uterus simultaneously with bacterial infection, reducing it by 75% when administered intravenously at the same time as IU bacterial inoculation, and by 48% when administered intravenously 4 h after IU bacterial infection. This effect on preterm delivery was accompanied by a parallel benefit on fetal survival in utero. SP-A had no effect on bacterial growth but reversed several major consequences of infection, including increased production of inflammatory mediators and a shift in macrophage polarization to the M1 phenotype. These findings suggest that exogenous SP-A has potential use to counteract infection-induced labor by reversing its proinflammatory consequences.

AB - The field of computational biology has become largely dependent on data visualization tools to analyze the increasing quantities of data gathered through the use of new and growing technologies. Aside from the volume, which often results in large amounts of noise and complex relationships with no clear structure, the visualization of biological data sets is hindered by their heterogeneity, as data are obtained from different sources and contain a wide variety of attributes, including spatial and temporal information. This requires visualization approaches that are able to not only represent various data structures simultaneously but also provide exploratory methods that allow the identification of meaningful relationships that would not be perceptible through data analysis algorithms alone. In this article, we present a survey of visualization approaches applied to the analysis of biological data. We focus on graph-based visualizations and tools that use coordinated multiple views to represent high-dimensional multivariate data, in particular time series gene expression, protein-protein interaction networks and biological pathways. We then discuss how these methods can be used to help solve the current challenges surrounding the visualization of complex biological data sets. PMID- 29590304 TI - Long-term Thromboembolic Risk in Patients With Postoperative Atrial Fibrillation After Coronary Artery Bypass Graft Surgery and Patients With Nonvalvular Atrial Fibrillation. AB - Importance: New-onset postoperative atrial fibrillation (POAF) is a common complication of coronary artery bypass graft (CABG) surgery. However, the long term risk of thromboembolism in patients who develop POAF after CABG surgery remains unknown. In addition, information on stroke prophylaxis in this setting is lacking. Objective: To examine stroke prophylaxis and the long-term risk of thromboembolism in patients with new-onset POAF after first-time isolated CABG surgery compared with patients with nonsurgical, nonvalvular atrial fibrillation (NVAF). Design, Setting, and Participants: This cohort study used data from a clinical cardiac surgery database and Danish nationwide registries to identify patients undergoing first-time isolated CABG surgery who developed new-onset POAF from January 1, 2000, through June 30, 2015. These patients were matched by age, sex, CHA2DS2-VASc score, and year of diagnosis to patients with nonsurgical NVAF in a 1 to 4 ratio. Data analysis was completed from February 2017 to January 2018. Main Outcomes and Measures: The proportion of patients initiating oral anticoagulation therapy within 30 days and the rates of thromboembolism. Results: A total of 2108 patients who developed POAF after CABG surgery were matched with 8432 patients with NVAF. In the full population of 10 540 patients, the median (interquartile range) age was 69.2 (63.7-74.7) years; 8675 patients (82.3%) were men. Oral anticoagulation therapy was initiated within 30 days postdischarge in 175 patients with POAF (8.4%) and 3549 patients with NVAF (42.9%). The risk of thromboembolism was lower in the POAF group than in the NVAF group (18.3 vs 29.7 events per 1000 person-years; adjusted hazard ratio [HR], 0.67; 95% CI, 0.55 0.81; P < .001). Anticoagulation therapy during follow-up was associated with a lower risk of thromboembolic events in both patients with POAF (adjusted HR, 0.55; 95% CI, 0.32-0.95; P = .03) and NVAF (adjusted HR, 0.59; 95% CI, 0.51-0.68; P < .001) compared with patients who did not receive any anticoagulation therapy. Further, the risk of thromboembolism was not significantly higher in patients with POAF compared with those who did not develop POAF after CABG surgery (adjusted HR, 1.11; 95% CI, 0.94-1.32; P < .24). Conclusions and Relevance: New onset POAF in patients who had undergone CABG surgery was associated with a lower long-term thromboembolic risk than that of patients who had NVAF. These data do not support the notion that new-onset POAF should be regarded as equivalent to primary NVAF in terms of long-term thromboembolic risk.

AB - Background: Silicone elastomer, a ubiquitous biomaterial and main constituent of breast implants, has been used for breast augmentation and reconstruction for over 50 years. Breast implants have direct local and purported systemic effects on normal tissue homeostasis dictated by the chemical and physical presence of the implant. Objectives: Protein adsorption has been demonstrated to be a key driver of local reactions to silicone. We sought to develop an assay and identify the proteins that coat implants during breast implantation. Methods: Wound fluid was salvaged from women who had undergone breast reduction and incubated in contact with the surface of 13 commercially available implant surfaces. An in situ digestion technique was optimized to elute bound proteins. Samples were analyzed on an Orbitrap elite analyser, proteins identified in Mascot Demon and analyzed in Progenesis. Results: A total of 822 proteins were identified, bound to the surfaces of the implants. Extracellular proteins were the most abundant ontology, followed by intracellular proteins. Fibrinogen, a proinflammatory protein and Albumin, an anti-inflammatory protein had significant (P < 0.0001) binding differences between the surfaces studied. Complement C3, C5, and factor H were also shown to have significantly different binding affinities for the implants included in the study (P < 0.05). Conclusions: We have developed a novel assay of breast implant protein binding and demonstrated significant binding affinities for relevant proteins derived from breast tissue wound fluid.

PMID- 29590307 TI - Mutations causing specific arrests in the development of mouse primordial germ cells and gonocytes. AB - This review focuses on those mouse mutations that cause an effect on the morphology, viability, and/or behavior of primordial germ cells (PGCs) and gonocytes at specific steps of their fetal development up to the start of spermatogenesis, a few days after birth. To restrict the area covered, mice with mutations that cause abnormal hormone levels or mutations of genes not expressed in germ cells that secondarily cause spermatogenic problems are not discussed. To make our literature search as comprehensive as possible, Pubmed was searched for "(primordial germ cells OR prospermatogonia OR prespermatogonia OR gonocytes OR spermatogonia or meiosis or spermiogenesis or spermatogenesis) AND mouse AND (knockout or mutant or transgenic)." This search started at 2003 as mutants created earlier were already retrieved for a previous review. The resulting citations were then further selected for complete or partial arrests at the level of PGCs and/or gonocytes. Fifty-nine protein coding genes and two miRNA coding genes were found that arrest the development of PGCs and gonocytes at specific steps providing a better insight into the regulation of the development of these cells. As to be expected, often problems in fetal germ cell development have an effect on the fertility of the mice at adulthood. PMID- 29590309 TI - Generalizing biomedical relation classification with neural adversarial domain adaptation. AB - Motivation: Creating large datasets for biomedical relation classification can be prohibitively expensive. While some datasets have been curated to extract protein protein and drug-drug interactions (PPIs and DDIs) from text, we are also interested in other interactions including gene-disease and chemical-protein connections. Also, many biomedical researchers have begun to explore ternary relationships. Even when annotated data are available, many datasets used for relation classification are inherently biased. For example, issues such as sample selection bias typically prevent models from generalizing in the wild. To address the problem of cross-corpora generalization, we present a novel adversarial learning algorithm for unsupervised domain adaptation tasks where no labeled data are available in the target domain. Instead, our method takes advantage of unlabeled data to improve biased classifiers through learning domain-invariant features via an adversarial process. Finally, our method is built upon recent advances in neural network (NN) methods. Results: We experiment by extracting PPIs and DDIs from text. In our experiments, we show domain invariant features can be learned in NNs such that classifiers trained for one interaction type (protein-protein) can be re-purposed to others (drug-drug). We also show that our method can adapt to different source and target pairs of PPI datasets. Compared to prior convolutional and recurrent NN-based relation classification methods without domain adaptation, we achieve improvements as high as 30% in F1-score. Likewise, we show improvements over state-of-the-art adversarial methods. Availability and implementation: Experimental code is available at https://github.com/bionlproc/adversarial-relation-classification.

PMID- 29590310 TI - Mouse oocytes connect with granulosa cells by fusing with cell membranes and form a large complex during follicle development. AB - Proper development and maturation of oocytes requires interaction with granulosa cells. Previous reports have indicated that mammalian oocytes connect with cumulus cells through gap junctions at the tip of transzonal projections that extend from the cells. Although the gap junctions between oocytes and transzonal projections provide a pathway through which small molecules (<1 kDa) can travel, it is unclear how molecules >1 kDa are transported between the oocytes and cumulus cells. In this study, we presented new connections between oocytes and granulosa cells. The green fluorescein protein Aequorea coerulescens green fluorescein protein (AcGFP1) localizing in oocyte cell membrane, 1,1'-dioctadecyl 3,3,3',3'-tetramethylindocarbocyanine perchlorate and dextran conjugates (10,000 MW) injected into the oocytes, which were unable to pass through gap junctions, were diffused from the oocytes into the surrounding granulosa cells through these connections. These connect an oocyte to the surrounding cumulus and granulosa cells by fusing with the cell membranes and forming a large complex during follicle development. Furthermore, we show two characteristics of these connections during follicle development-the localization of growth and differentiation factor-9 within the connections and the dynamics of the connections at ovulation. This article presents for the first time that mammalian oocytes directly connect to granulosa cells by fusing with the cell membrane, similar to that in Drosophila.

AB - Background: Primaquine is the only drug providing radical cure of Plasmodium vivax malaria. It is not recommended for breastfeeding women as it causes hemolysis in glucose-6-phosphate dehydrogenase (G6PD)-deficient individuals, and breast milk excretion and thus infant exposure are not known. Methods: Healthy G6PD-normal breastfeeding women with previous P. vivax infection and their healthy G6PD-normal infants between 28 days and 2 years old were enrolled. Mothers took primaquine 0.5 mg/kg/day for 14 days. Primaquine and carboxyprimaquine concentrations were measured in maternal venous plasma, capillary plasma, and breast milk samples and infant capillary plasma samples taken on days 0, 3, 7, and 13. Results: In 20 mother-infant pairs, primaquine concentrations were below measurement thresholds in all but 1 infant capillary plasma sample (that contained primaquine 2.6 ng/mL), and carboxyprimaquine was likewise unmeasurable in the majority of infant samples (maximum value 25.8 ng/mL). The estimated primaquine dose received by infants, based on measured breast milk levels, was 2.98 ug/kg/day (ie, ~0.6% of a hypothetical infant daily dose of 0.5 mg/kg). There was no evidence of drug-related hemolysis in the infants. Maternal levels were comparable to levels in nonlactating patients, and adverse events in mothers were mild. Conclusions: The concentrations of primaquine in breast milk are very low and therefore very unlikely to cause adverse effects in the breastfeeding infant. Primaquine should not be withheld from mothers breastfeeding infants or young children. More information is needed in neonates. Clinical Trials Registration: NCT01780753. PMID- 29590313 TI - Follow-Up Data Improve the Estimation of the Prevalence of Heavy Alcohol Consumption. AB - Aims: We aim to adjust for potential non-participation bias in the prevalence of heavy alcohol consumption. Methods: Population survey data from Finnish health examination surveys conducted in 1987-2007 were linked to the administrative registers for mortality and morbidity follow-up until end of 2014. Utilising these data, available for both participants and non-participants, we model the association between heavy alcohol consumption and alcohol-related disease diagnoses. Results: Our results show that the estimated prevalence of heavy alcohol consumption is on average of 1.5 times higher for men and 1.8 times higher for women than what was obtained from participants only (complete case analysis). The magnitude of the difference in the mean estimates by year varies from 0 to 9 percentage points for men and from 0 to 2 percentage points for women. Conclusion: The proposed approach improves the prevalence estimation but requires follow-up data on non-participants and Bayesian modelling. PMID- 29590314 TI - Altruistic decisions following penetrating traumatic brain injury. AB - The cerebral correlates of altruistic decisions have increasingly attracted the interest of neuroscientists. To date, investigations on the neural underpinnings of altruistic decisions have primarily been conducted in healthy adults undergoing functional neuroimaging as they engaged in decisions to punish third parties. The chief purpose of the present study was to investigate altruistic decisions following focal brain damage with a novel altruistic decision task. In contrast to studies that have focused either on altruistic punishment or donation, the Altruistic Decision Task allows players to anonymously punish or donate to 30 charitable organizations involved with salient societal issues such as abortion, nuclear energy and civil rights. Ninety-four Vietnam War veterans with variable patterns of penetrating traumatic brain injury and 28 healthy veterans who also served in combat participated in the study as normal controls. Participants were asked to invest $1 to punish or reward real societal organizations, or keep the money for themselves. Associations between lesion distribution and performance on the task were analysed with multivariate support vector regression, which enables the assessment of the joint contribution of multiple regions in the determination of a given behaviour of interest. Our main findings were: (i) bilateral dorsomedial prefrontal lesions increased altruistic punishment, whereas lesions of the right perisylvian region and left temporo insular cortex decreased punishment; (ii) altruistic donations were increased by bilateral lesions of the dorsomedial parietal cortex, whereas lesions of the right posterior superior temporal sulcus and middle temporal gyri decreased donations; (iii) altruistic punishment and donation were only weakly correlated, emphasizing their dissociable neuroanatomical associations; and (iv) altruistic decisions were not related to post-traumatic personality changes. These findings indicate that altruistic punishment and donation are determined by largely non overlapping cerebral regions, which have previously been implicated in social cognition and moral experience such as evaluations of intentionality and intuitions of justice and morality.10.1093/brain/awy064_video1awy064media15758316955001. PMID- 29590316 TI - 'No, the government doesn't need to, it's already self-regulated': a qualitative study among vape shop operators on perceptions of electronic vapor product regulation. AB - While the market share of electronic vapor products (EVPs), sold primarily through vape shops and other outlets, has increased rapidly, these products remained largely unregulated until 2016. This study, conducted prior to announcement of the deeming regulations, provides insights into vape shop operator attitudes toward potential government regulations of EVPs. In 2015, we conducted 37 in-person interviews of vape shop operators across nine US cities. Shops were identified through extensive web-searches. We used QSR International's NVivo 11 qualitative data analysis software to analyze the transcripts. Many vape shop operators viewed regulations requiring safe production of e-liquids, child resistant bottles and listing e-juice ingredients as acceptable. They disagreed with the elimination of free samples and bans on flavored e-liquid sales, which generate significant revenue for their stores. Many held negative perceptions of pre-market review of new product lines and EVP-specific taxes. All agreed that EVPs should not be sold to minors, but most felt that owners should not be fined if minors visited vape shops. Findings from this study offer insights into the acceptability of proposed regulations, as well as barriers to effective regulation implementation. PMID- 29590317 TI - Alteration of transporter activities in the epididymides of infertile initial segment-specific Pten knockout mice. AB - A fully functional initial segment, the most proximal region of the epididymis, is important for male fertility. Our previous study generated a mouse model to investigate the importance of initial segment function in male fertility. In that model, phosphatase and tensin homolog (Pten) was conditionally removed from the initial segment epithelium, which resulted in epithelial de-differentiation. When spermatozoa progressed through the de-differentiated epithelial duct, they developed angled flagella, suggesting compromised sperm maturation, which eventually resulted in male infertility. To understand the molecular mechanisms, by which PTEN regulates epididymal sperm maturation, we compared the transcriptome profile of the initial segment between controls and initial segment specific Pten knockouts and revealed that water, ion, and organic solute transporter activities were one of the top molecular and cellular functions altered following loss of Pten. Alteration in protein levels and localization of several transporters following loss of Pten were also observed by immunofluorescence analysis. Epithelial cells of the initial segment from knockouts were more permeable to fluorescein isothiocyanate-dextran (4000 Da) compared to controls. Interestingly, conditional deletion of Pten from other organs also resulted in changes in transporter activity, suggesting a common role of PTEN in regulation of transporter activity. Taken together, our data support the hypothesis that loss of Pten from the initial segment epithelium results in changes in the transporting and permeability characteristics of the epithelium, which in turn altered the luminal fluid microenvironment that is so important for sperm maturation and male fertility. PMID- 29590315 TI - Association of Brain Cortical Changes With Relapse in Patients With Major Depressive Disorder. AB - Importance: More than half of all patients with major depressive disorder (MDD) experience a relapse within 2 years after recovery. It is unclear how relapse affects brain morphologic features during the course of MDD. Objective: To use structural magnetic resonance imaging to identify morphologic brain changes associated with relapse in MDD. Design, Setting, and Participants: In this longitudinal case-control study, patients with acute MDD at baseline and healthy controls were recruited from the University of Munster Department of Psychiatry from March 21, 2010, to November 14, 2014, and were reassessed from November 11, 2012, to October 28, 2016. Depending on patients' course of illness during follow up, they were subdivided into groups of patients with and without relapse. Whole brain gray matter volume and cortical thickness of the anterior cingulate cortex, orbitofrontal cortex, middle frontal gyrus, and insula were assessed via 3-T magnetic resonance imaging at baseline and 2 years later. Main Outcomes and Measures: Gray matter was analyzed via group (no relapse, relapse, and healthy controls) by time (baseline and follow-up) analysis of covariance, controlling for age and total intracranial volume. Confounding factors of medication and depression severity were assessed. Results: This study included 37 patients with MDD and a relapse (19 women and 18 men; mean [SD] age, 37.0 [12.7] years), 23 patients with MDD and without relapse (13 women and 10 men; mean [SD] age, 32.5 [10.5] years), and 54 age- and sex-matched healthy controls (24 women and 30 men; mean [SD] age, 37.5 [8.7] years). A significant group-by-time interaction controlling for age and total intracranial volume revealed that patients with relapse showed a significant decline of insular volume (difference, -0.032; 95% CI, -0.063 to -0.002; P = .04) and dorsolateral prefrontal volume (difference, 0.079; 95% CI, -0.113 to -0.045; P < .001) from baseline to follow-up. In patients without relapse, gray matter volume in these regions did not change significantly (insula: difference, 0.027; 95% CI, -0.012 to 0.066; P = .17; and dorsolateral prefrontal volume: difference, 0.023; 95% CI, -0.020 to 0.066; P = .30). Volume changes were not correlated with psychiatric medication or with severity of depression at follow-up. Additional analysis of cortical thickness showed an increase in the anterior cingulate cortex (difference, 0.073 mm; 95% CI, 0.023-0.123 mm; P = .005) and orbitofrontal cortex (difference, 0.089 mm; 95% CI, 0.032-0.147 mm; P = .003) from baseline to follow-up in patients without relapse. Conclusion and Relevance: A distinct association of relapse in MDD with brain morphologic features was revealed using a longitudinal design. Relapse is associated with brain structures that are crucial for regulation of emotions and thus needs to be prevented. This study might be a step to guide future prognosis and maintenance treatment in patients with recurrent MDD.

PMID- 29590318 TI - Intestinal Barrier Dysfunction and Microbial Translocation in Human Immunodeficiency Virus-Infected Pregnant Women Are Associated With Preterm Birth. AB - Background: Preterm birth (PTB) rates are high in human immunodeficiency virus (HIV)-infected populations, even when on treatment. Still, only a subset of all births in HIV-infected pregnant women result in PTB, suggesting that risk factors other than HIV infection itself are also important. Inflammation is a known risk factor in uninfected populations, but its role in HIV-infected population have not been studied; in addition, the immune pathways involved are not clear and noninvasive immune markers with predictive value are lacking. Our objective was to determine the association of select markers of inflammation with PTB in HIV-1 infected pregnant women. Methods: Within a randomized trial of pregnant women receiving nevirapine (Six-Week Extended-Dose Nevirapine [SWEN] trial), we nested a case-control study (n = 107; 26 cases, 81 controls) to determine the association of maternal inflammation with PTB. Cases were defined as PTB (<37 weeks' gestational age). We assessed inflammation by measuring plasma levels of markers of general inflammation (C-reactive protein [CRP]), intestinal barrier dysfunction (intestinal fatty acid binding protein [I-FABP]), and microbial translocation/monocyte activation (soluble CD14 [sCD14] and CD163 [sCD163]). Multivariable logistic regression was used to determine the odds of PTB per log2 increase of each marker. Results: In multivariable models, there was increased odds of PTB per unit increase of log2 sCD14 (adjusted odds ratio [aOR], 2.45; 95% confidence interval [CI], 1.24-4.86), log2 sCD163 (aOR, 3.87; 95% CI, 1.43 10.49), and log2 I-FABP (aOR, 2.28; 95% CI, 1.18-4.41) but not log2 CRP (aOR, 0.72; 95% CI, .48-1.09). Conclusions: Our results show that select immune markers can identify women at higher risk for PTB in HIV-1-infected populations and suggest that modulating gut barrier integrity and microbial translocation may affect PTB.

AB - BACKGROUND: Hypertension affects 33% of Americans while type 2 diabetes and Alzheimer's disease (AD) affect 10% of Americans, respectively. Ryanodine receptor 3 gene (RYR3) codes for the RYR which functions to release stored endoplasmic reticulum calcium ions (Ca2+) to increase intracellular Ca2+ concentration. Increasing studies demonstrate that altered levels of intracellular Ca2+ affect cardiac contraction, insulin secretion, and neurodegeneration. In this study, we investigated associations of the RYR3 genetic variants with hypertension, AD, and diabetes. METHODS: Family data sets were used to explore association of RYR3 polymorphisms with risk and age at onset (AAO) of hypertension, diabetes, and AD. RESULTS: Family-based association tests using generalized estimating equations (FBAT-GEE) showed several unique or shared disease-1 associated variants in the RYR3 gene. Three single nuclear polymorphisms (SNPs; rs2033610, rs2596164, and rs2278317) are significantly associated with risk for hypertension, diabetes, and AD. Two SNPs (rs4780174 and rs7498093) are significantly associated with AAO of the 3 diseases. CONCLUSIONS: RYR3 variants are associated with hypertension, diabetes, and AD. Replication of these results of this gene in these 3 complex traits may help to better understand the genetic basis of calcium-signaling gene, RYR3 in association with risk and AAO of these diseases.

PMID- 29590324 TI - Universal school lunch programme closes a socioeconomic gap in fruit and vegetable intakes among school children in Japan. AB - Background: Universal school lunch programmes are expected to cover all children equally, compared with selective programmes that may stigmatize socially vulnerable children. However, the effectiveness of universal programmes in closing dietary disparity has not been empirically proven. We evaluated whether Japan's universal school lunch programmes contribute to a reduction in the socioeconomic status (SES)-related gradient in fruit and vegetable intakes. Methods: We analyzed data for 719 school children aged 6-12 years in a population based survey conducted in the greater Tokyo metropolitan area. We measured dietary intakes using a validated self-administered brief diet history questionnaire for young children (BDHQ-10 y). We assessed parental education, annual household income and maternal employment status as SES indicators of children. We used multiple regression to estimate mean fruit and vegetable intakes by parental education and household income, and the contribution of school lunch to reducing the SES-related gradient in fruit and vegetable intakes. Results: Compared with children with high maternal education (>15 years), those with low maternal education (<13 years) had less vegetable intake by 22.3 g/1000 kcal (95% confidence interval = 12.5, 32.2) and less fruit intake by 7.5 g/1000 kcal (95% confidence interval = -2.4, 17.3). However, fruit and vegetable intakes from school lunch did not vary by SES, indicating that school lunch intake alleviated the SES-related gradient of total vegetable intake by 9.9% and that of fruit intake by 3.4%. Conclusions: Universal school lunch programmes can partially contribute to a reduction in the SES-related gradient in dietary intakes. PMID- 29590325 TI - Real-time Monitoring using a breathalyzer-based eHealth system can identify lapse/relapse patterns in alcohol use disorder Patients. AB - Aim: We introduce a new remote real-time breathalyzer-based method for monitoring and early identification of lapse/relapse patterns for alcohol use disorder (AUD) patients using a composite measure of sobriety, the Addiction Monitoring Index (AMI). Methods: We constructed AMI from (a) obtained test results and (b) the pattern of ignored tests using data from the first 30 patients starting in the treatment arms of two on-going clinical trials. The patients performed 2-4 scheduled breath alcohol content (BrAC)-tests per day presented as blood alcohol content (BAC) data. In total, 10,973 tests were scheduled, 7743 were performed and 3230 were ignored during 3982 patient days. Results: AMI-time profiles could be used to monitor the daily trends of alcohol consumption and detect early signs of lapse and relapses. The pattern of ignored tests correlates with the onset of drinking. AMI correlated with phosphatidyl ethanol (n = 61, F-ratio = 34.6, P < 0.0001, R = -0.61). The recognition of secret drinking could further be improved using a low alcohol detection threshold (BrAC = 0.025 mg/l, BACSwe = 0.050/00 or US = 0.0053g/dl), in addition to the legal Swedish traffic limit (BrAC = 0.1 mg/l, BACSwe = 0.20/00 or US = 0.021 g/dl). Nine out of 10 patients who dropped out from the study showed early risk signs as reflected in the level and pattern in AMI before the actual dropout. Conclusions: AMI-time profiles from an eHealth system are useful for monitoring the recovery process and for early identification of lapse/relapse patterns. High-resolution monitoring of sobriety enables new measurement-based treatment methods for proactive personalized long term relapse prevention and treatment of AUD patients. Clinical Trial Registration: The data used for construction of AMI was from two clinical trials approved by the Regional Ethics Committee of Uppsala, Sweden and performed in accordance with the Declaration of Helsinki. Written informed consent was obtained from all participating subjects. The study was registered at ClinicalTrials.gov (NCT03195894). PMID- 29590327 TI - Is Scottish Intercollegiate Guidelines Network guidance for GP management of tonsillitis suitable? A qualitative study. AB - Background: The Scottish Intercollegiate Guidelines Network (SIGN) developed guidelines for the management of sore throat and indications for tonsillectomy in 1999 to address concerns of unnecessary surgery. Emergency admissions to hospital for tonsillitis have since increased. Adults experience an average of 27 episodes of tonsillitis before undergoing tonsillectomy. We wished to explore the appropriateness of the guidance and/or its implementation in primary care. Aim: To explore the attitudes of GPs to the referral criteria they use when managing adults presenting with acute tonsillitis. Design: Secondary analysis of qualitative data from the NAtional Trial of Tonsillectomy IN Adults (NATTINA) feasibility and process evaluation. Participants and Setting: Twenty-one GPs from practices throughout the UK. Method: In-depth interviews with GPs concerning both the feasibility and process evaluation phases of NATTINA. Analysis was conducted using the framework method. Results: GPs felt it was rarely necessary to refer patients. They were aware of guidelines and would refer if requested by a patient who fulfilled the guidelines criteria and/or who were missing considerable amounts of work. Conclusion: The introduction of the guidelines appears to coincide with what some may have hoped to be a desired effect of reducing adult sore throat referrals and subsequent tonsillectomies by increasing the number of episodes a patient must suffer before the referral threshold is met. GPs may find equipoise for tonsillectomy referral challenging as many patients express a strong preference for surgery. We believe this paper reinforces GP professionalism and patient-centred consultations, and challenges the role of clinical guidelines. PMID- 29590326 TI - Safety and Immunogenicity of Zoster Vaccine Live in Human Immunodeficiency Virus Infected Adults With CD4+ Cell Counts >200 Cells/mL Virologically Suppressed on Antiretroviral Therapy. AB - Background: Herpes zoster (HZ) risk is increased in human immunodeficiency virus (HIV)-infected persons. Live attenuated zoster vaccine (ZV) reduces HZ incidence and severity in adults; safety and immunogenicity data in HIV-infected adults are limited. Methods: We conducted a randomized, double-blind, placebo-controlled trial in HIV-infected adults virally suppressed on antiretroviral therapy (ART). Participants, stratified by CD4+ count (200-349 or >=350 cells/uL), were randomized 3:1 to receive ZV or placebo on day 0 and week 6. The primary endpoint was serious adverse event or grade 3/4 signs/symptoms within 6 weeks after each dose. Immunogenicity (varicella zoster virus [VZV]-specific glycoprotein enzyme linked immunosorbent assay and interferon-gamma enzyme-linked immunospot assay responses) was assessed at 6 and 12 weeks postvaccination. Results: Of 395 participants (296 ZV vs 99 placebo), 84% were male, 47% white, 29% black, and 22% Hispanic; median age was 49 years. Safety endpoints occurred in 15 ZV and 2 placebo recipients (5.1% [95% confidence interval {CI}, 2.9%-8.2%] vs 2.1% [95% CI, .3%-7.3%]; P = .26). Injection site reactions occurred in 42% of ZV (95% CI, 36.3%-47.9%) vs 12.4% of placebo recipients (95% CI, 6.6%-20.6%) (P < .001). Week 12 median natural log VZV antibody titer was higher for ZV (6.30 [Q1, Q3, 5.64, 6.96]) vs placebo (5.48 [Q1, Q3, 4.63, 6.44]; P < .001) overall and in the high CD4+ stratum (P = .003). VZV antibody titers were similar after 1 or 2 ZV doses. Polymerase chain reaction-confirmed HZ occurred in 2 participants (1 ZV; 1 placebo); none was vaccine strain related. Conclusions: Two doses of ZV in HIV infected adults suppressed on ART with CD4+ counts >=200 cells/uL were safe and immunogenic. Clinical Trials Registration: NCT00851786. PMID- 29590328 TI - Association between adolescents' academic aspirations and expectations and mental health: a one-year follow-up study. AB - Background: Mental health problems among youth have increased in Sweden in recent decades, as has competition in higher education and the labour market. It is unknown whether the increasing emphasis put on educational achievement might negatively affect adolescents' mental health. We aimed to investigate the relationship between adolescents' academic aspirations and expectations and the risk of mental health problems. Methods: We studied 3343 Swedish 7th grade adolescents (age 13), who participated in the first two waves of the KUPOL longitudinal study; participants answered a questionnaire encompassing the five item Future Aspirations and Goals (FG) subscale of the Student Engagement Instrument, two questions about their own academic aspirations and expectations and two mental health instruments: the Center for Epidemiological studies for Children (CES-DC) (alpha=.90) and the Strengths and Difficulties Questionnaire (SDQ) (alpha=.78). The association between aspirations and expectations at baseline and mental health at follow-up was analysed using logistic regression models adjusting for baseline mental health, socio-demographic and family factors. Results: The FG subscale was inversely and linearly associated with the odds of high CES-DC score [adjusted OR (odds ratio) 0.71, 95% CI (confidence interval): 0.59-0.86], total Strengths and Difficulties Questionnaire score (OR 0.59, 95% CI 0.49-0.71), and its internalizing (OR 0.70, 95% CI 0.59-0.84) and externalizing problems scores (OR 0.58, 95% CI 0.48-0.71). Conclusions: Adolescents with high individual academic aspirations have less mental health problems at 1-year follow-up. Future studies should investigate whether interventions aimed at increasing aspirations and engagement in school may prevent mental health problems in adolescence. PMID- 29590329 TI - Association of Author Gender With Sex Bias in Surgical Research. AB - Importance: Previous studies demonstrate sex bias in surgical research. Female participants and investigators are underrepresented in surgical scientific research. Objectives: To describe the distribution of male and female authors in 5 general-interest surgery journals, assess the association of author gender with sex bias, and explore whether investigators benefit from performing sex-inclusion research. Design, Setting, and Participants: For this bibliometric analysis, data were abstracted from 1921 original, peer-reviewed articles published from January 1, 2011, through December 31, 2012, in Annals of Surgery, American Journal of Surgery, JAMA Surgery, The Journal of Surgical Research, and Surgery. Excluded articles pertained to a sex-specific disease or did not report the number of study participants. An additional 119 articles contained gender-ambiguous author names and were omitted. Data were analyzed from April to June 2017. Main Outcomes and Measures: Male and female first and senior authors, number of female and male participants in each study, surgical specialty, and number of citations received per article. Results: Of the 3604 authors of 1802 articles included in this study, 2791 first and senior authors (77.4%) were male and 813 (22.6%) were female. The prevalence of male and female authors was consistent across all 5 journals and among clinical and basic science research. Articles by female authors included a higher median number of female study participants compared with their male counterparts (27.5 vs 16.0; P = .01), but sex matched the inclusion of participants less frequently (36% vs 45%; P = .001). No sex-based differences occurred between male and female authors in reporting, statistical analysis, and discussion of the data or in the number of citations received. Compared with studies that did not report, analyze, or discuss data by sex, studies that performed sex-specific data reporting yielded a mean of 2.8 more citations (95% CI, 1.2-4.4; P = .001); those that performed statistical analysis, a mean of 3.5 more citations (95% CI, 1.8-5.1; P = .001); and those that discussed the data, a mean of 2.6 more citations (95% CI, 0.7-4.5; P = .001). Articles with a higher percentage of sex matching of participants also received more citations, with an increase of 1 citation per 4.8% (95% CI, 2.0%-7.7%; P = .001) increase in percentage of sex matching. Conclusions and Relevance: Sex bias in surgical research is prevalent among male and female authors; however, female authors included proportionally more female participants in their studies compared with male authors. Notably, studies that addressed sex bias were rewarded by the scientific community with increased citations of their published work. PMID- 29590330 TI - Arterial stiffening is a heritable trait associated with arterial dilation but not wall thickening: a longitudinal study in the twins UK cohort. AB - Aims: Vascular ageing is characterized by arterial stiffening, dilation, and arterial wall thickening. We investigated the extent to which these changes are related and their heritability during 5 year follow-up in the Twins UK cohort. Methods and results: Carotid-femoral pulse wave velocity (PWVcf), carotid diameter, carotid distensibility, and carotid intima-media thickness (IMT) were measured in 762 female twins (mean age 57.9 +/- 8.6 years) at two time-points over an average follow-up of 4.9 +/- 1.5 years. Magnetic resonance imaging (MRI) was performed in a sub-sample of 38 women to measure aortic pulse wave velocity (PWVaorta), diameter, and wall thickness. Heritability of changes in arterial wall properties was estimated using structural equation modelling. Annual increases in PWVcf, carotid diameter, distensibility, and IMT were 0.139 m/s, 0.028 mm, -0.4 kPa-1, and 0.011 mm per year, respectively. In regression analysis, predictors of progression in PWVcf included age, mean arterial pressure (MAP), and heart rate (HR) at baseline, and progression in MAP, HR, and body mass index (BMI). Predictors of progression in IMT included progression in MAP, BMI, and triglyceride levels. Progression of PWV and distensibility correlated with progression in carotid diameter but not with IMT. Heritability of progression of PWVcf, diameter, and IMT was 55%, 21%, and 8%, respectively. In a sub-sample of women that underwent MRI, aortic wall thickness increased by 0.19 mm/year, but aortic wall thickening was not correlated with an increase in lumen diameter or PWVaorta. Conclusion: Arterial stiffening, as measured by PWVcf, and dilation are heritable but independent of arterial wall thickening. Genetic and cardiovascular risk factors contribute differently to progression of PWV and IMT. PMID- 29590331 TI - Heat Strain and Hydration of Japanese Construction Workers during Work in Summer. AB - Objectives: The aim was to ascertain hydration and heat strain of construction workers in Japan during the summer who are at the highest risk of heat-related disorders. Methods: The subjects were 23 construction workers, whose average age was 41, average weight was 69 kg, and average height was 170 cm. We measured thermal working conditions with a wet bulb globe temperature (WBGT) measurement instrument affixed to the helmet of each worker, at fixed points outdoors in the sun and indoors. Heat strain was evaluated for water intake, urine specific gravity (Usg), urine temperature (UT), heart rate (HR), and body weight during work. Results: The average WBGT measured on the worker helmets over 3 consecutive days was 28.0 +/- 0.7, 27.6 +/- 0.8, and 27.6 +/- 1.1 degrees C. The average water intake was 2.6 l during a work shift. The average Usg, UT, and % HR reserve were the highest in the first half of afternoon work. Seventy-eight percent of the subjects exceeded at least one of the ACGIH TLV physiological guidelines for heat strain in terms of HR and weight loss or a clinically dehydrated level of Usg. Conclusions: Heat strain was the highest in the first half of afternoon work. The number of dehydrated workers increased during this shift because of insufficient water intake. Adequate hydration is required to decrease the risk of heat-related disorders among construction workers in the summer.

AB - Aims: HIV-positive persons have increased cardiovascular event rates but data on the prevalence of subclinical atherosclerosis compared with HIV-negative persons are not uniform. We assessed subclinical atherosclerosis utilizing coronary artery calcium (CAC) scoring and coronary computed tomography angiography (CCTA) in 428 HIV-positive participants of the Swiss HIV Cohort Study and 276 HIV negative controls concurrently referred for clinically indicated CCTA. Methods and results: We assessed the association of HIV infection, cardiovascular risk profile, and HIV-related factors with subclinical atherosclerosis in univariable and multivariable analyses. HIV-positive participants (median duration of HIV infection, 15 years) were younger than HIV-negative participants (median age 52 vs. 56 years; P < 0.01) but had similar median 10-year Framingham risk scores (9.0% vs. 9.7%; P = 0.40). The prevalence of CAC score >0 (53% vs. 56.2%; P = 0.42) and median CAC scores (47 vs. 47; P = 0.80) were similar, as was the prevalence of any, non-calcified/mixed, and high-risk plaque. In multivariable adjusted analysis, HIV-positive participants had a lower prevalence of calcified plaque than HIV-negative participants [36.9% vs. 48.6%, P < 0.01; adjusted odds ratio (aOR) 0.57; 95% confidence interval (CI) 0.40-0.82; P < 0.01], lower coronary segment severity score (aOR 0.72; 95% CI 0.53-0.99; P = 0.04), and lower segment involvement score (aOR 0.71, 95% CI 0.52-0.97; P = 0.03). Advanced immunosuppression was associated with non-calcified/mixed plaque (aOR 1.97; 95% CI 1.09-3.56; P = 0.02). Conclusion: HIV-positive persons in Switzerland had a similar degree of non-calcified/mixed plaque and high-risk plaque, and may have less calcified coronary plaque, and lower coronary atherosclerosis involvement and severity scores than HIV-negative persons with similar Framingham risk scores. PMID- 29590333 TI - Patent foramen ovale closure vs. medical therapy for cryptogenic stroke: a meta analysis of randomized controlled trials. AB - Aims: The efficacy of patent foramen ovale (PFO) closure for cryptogenic stroke has been controversial. We undertook a meta-analysis of randomized controlled trials (RCTs) comparing device closure with medical therapy to prevent recurrent stroke for patients with PFO. Methods and results: We systematically identified all RCTs comparing device closure to medical therapy for cryptogenic stroke in patients with PFO. The primary efficacy endpoint was recurrent stroke, analysed on an intention-to-treat basis. The primary safety endpoint was new onset atrial fibrillation (AF). Five studies (3440 patients) were included. In all, 1829 patients were randomized to device closure and 1611 to medical therapy. Across all patients, PFO closure was superior to medical therapy for prevention of stroke [hazard ratio (HR) 0.32, 95% confidence interval (95% CI) 0.13-0.82; P = 0.018, I2 = 73.4%]. The risk of AF was significantly increased with device closure [risk ratio (RR) 4.68, 95% CI 2.19-10.00, P<0.001, heterogeneity I2 = 27.5%)]. In patients with large shunts, PFO closure was associated with a significant reduction in stroke (HR 0.33, 95% CI 0.16-0.72; P = 0.005), whilst there was no significant reduction in stroke in patients with a small shunt (HR 0.90, 95% CI 0.50-1.60; P = 0.712). There was no effect from the presence or absence of an atrial septal aneurysm on outcomes (P = 0.994). Conclusion: In selected patients with cryptogenic stroke, PFO closure is superior to medical therapy for the prevention of further stroke: this is particularly true for patients with moderate-to-large shunts. Guidelines should be updated to reflect this. PMID- 29590336 TI - Importance of Objectively Comparing Local VA and Non-VA Care and Outcomes: Serving Veterans Well. PMID- 29590334 TI - A rare missense mutation in MYH6 associates with non-syndromic coarctation of the aorta. AB - Aims: Coarctation of the aorta (CoA) accounts for 4-8% of congenital heart defects (CHDs) and confers substantial morbidity despite treatment. It is increasingly recognized as a highly heritable condition. The aim of the study was to search for sequence variants that affect the risk of CoA. Methods and results: We performed a genome-wide association study of CoA among Icelanders (120 cases and 355 166 controls) based on imputed variants identified through whole-genome sequencing. We found association with a rare (frequency = 0.34%) missense mutation p.Arg721Trp in MYH6 (odds ratio = 44.2, P = 5.0 * 10-22), encoding the alpha-heavy chain subunit of cardiac myosin, an essential sarcomere protein. Approximately 20% of individuals with CoA in Iceland carry this mutation. We show that p.Arg721Trp also associates with other CHDs, in particular bicuspid aortic valve. We have previously reported broad effects of p.Arg721Trp on cardiac electrical function and strong association with sick sinus syndrome and atrial fibrillation. Conclusion: Through a population approach, we found that a rare missense mutation p.Arg721Trp in the sarcomere gene MYH6 has a strong effect on the risk of CoA and explains a substantial fraction of the Icelanders with CoA. This is the first mutation associated with non-familial or sporadic form of CoA at a population level. The p.Arg721Trp in MYH6 causes a cardiac syndrome with highly variable expressivity and emphasizes the importance of sarcomere integrity for cardiac development and function. PMID- 29590335 TI - First-line Raltegravir/Emtricitabine/Tenofovir Combination in Human Immunodeficiency Virus Type 2 (HIV-2) Infection: A Phase 2, Noncomparative Trial (ANRS 159 HIV-2). AB - Background: New options for first-line treatment of human immunodeficiency virus type 2 (HIV-2) infection are needed. We evaluated an integrase inhibitor (raltegravir)-containing regimen. Methods: Antiretroviral therapy (ART)-naive adults with symptomatic infection by HIV-2 only, CD4 count <500 cells/MUL or CD4 decrease >50 cells/MUL/year over the past 3 years, or a confirmed plasma HIV-2 RNA (pVL) load >=100 copies/mL were eligible for this noncomparative trial. The composite primary endpoint was survival at 48 weeks without any of the following: CD4 gain from baseline <100 cells/MUL, confirmed pVL >=40 copies/mL from week 24, raltegravir permanent discontinuation, or incident B or C event. HIV-2 ultrasensitive pVL (uspVL) and total DNA were assessed using in-house polymerase chain reaction (PCR) assays. Results: Baseline median CD4 count of 30 enrolled individuals (67% women) was 436 cells/uL (interquartile range [IQR], 314-507 cells/uL); pVL was >=40 copies/mL in 67% of them, uspVL was >=5 copies/mL in 92%, and total DNA was >6 copies by PCR in 32%. At week 48, the composite endpoint of success was reached in 40% [95% confidence interval, 22.7%-59.4%]. Failure was mainly (50%) due to CD4 gain <100 cells/uL; uspVL was <5 copies/mL in 87% and total DNA >6 copies by PCR in 12% of participants. Median CD4 gain was 87 cells/uL (IQR, 38-213 cells/uL; n = 28). No serious adverse reactions were reported. Conclusions: Raltegravir-containing ART is a safe option for first-line treatment of HIV-2 infection, yielding a comparable success rate to protease inhibitors. Clinical Trials Registration: NCT 01605890. PMID- 29590337 TI - Associations between physical fitness and adherence to the Mediterranean diet with health-related quality of life in adolescents: results from the LabMed Physical Activity Study. AB - Background: Physical fitness (PF) and adherence to the Mediterranean diet are important indicators of healthy lifestyles. The purpose of this study is to analyze the independent and combined associations between PF and adherence to Mediterranean diet with health-related quality of life (HRQoL) in adolescents. Methods: This is a cross-sectional analysis with 956 Portuguese adolescents aged 12-18 years. HRQoL was measured with the Kidscreen-10 questionnaire. PF was assessed with the ALPHA health-related fitness battery. The 20-m shuttle run test was used for the estimation of cardiorespiratory fitness; handgrip strength and standing long jump tests were applied for the assessment of muscular fitness and the 4 * 10 m shuttle run test for the assessment of motor fitness (speed and agility). The results of the PF tests (cardiorespiratory fitness, muscular fitness and motor fitness) were transformed into standardized values (Z-scores) by age and sex. Adherence to the Mediterranean diet was assessed with the KIDMED index. Regression analysis and analysis of covariance were performed. Results: PF (B = 0.228; P < 0.05) and adherence to the Mediterranean diet (B = 0.259; P < 0.05) were positively associated with HRQoL, after controlling for several variables. Participants classified as high PF and high adherence to Mediterranean diet had on average the highest HRQoL score compared with those with low PF and low adherence to Mediterranean diet (F(3, 939) = 4.270; P = 0.005), after adjustments for potential confounders. Conclusions: The combination of high PF levels and optimal adherence to Mediterranean diet is positively associated with HRQoL. PMID- 29590338 TI - An intervention that reduces stress in people who combine work with informal care: randomized controlled trial results. AB - Background: The aim of the research was to examine whether a role-focused self help course intervention would decrease caregiver stress and distress, and functioning problems, among people who suffer stress because they combine paid work with informal care. Methods: A pre-registered (NTR 5528) randomized controlled design was applied (intervention vs. wait list control). Participants (n = 128) were people who had paid work and were suffering stress due to their involvement in informal care activities. Participants allocated to the intervention group (n = 65) received the role-focused self-help course. Control group members (n = 63) received this intervention after all measurements. Prior to the random allocation (pre-test), and 1 month (post-test 1) and 2 months (post test 2) after allocation, all participants completed a questionnaire that measured their caregiver stress (primary outcome), distress, work functioning, negative care-to-work interference and negative care-to-social and personal life interference. Mixed model ANOVAs were used to test the effectiveness of the intervention. Results: Two months after allocation, the intervention group participants had lower levels of caregiver stress and distress compared with the control group participants. The intervention did not directly resolve impaired work functioning or interference of care with work and social/personal life. Conclusion: The intervention decreases caregiver stress and distress in people who suffer stress because they combine paid work with informal caring.

PMID- 29590340 TI - Exercise cardiac magnetic resonance to differentiate athlete's heart from structural heart disease. AB - Aims: The distinction between left ventricular (LV) dilation with mildly reduced LV ejection fraction (EF) in response to regular endurance exercise training and an early cardiomyopathy is a frequently encountered and difficult clinical conundrum. We hypothesized that exercise rather than resting measures would provide better discrimination between physiological and pathological LV remodelling and that preserved exercise capacity does not exclude significant LV damage. Methods and results: We prospectively included 19 subjects with LVEF between 40 and 52%, comprising 10 ostensibly healthy endurance athletes (EA healthy) and nine patients with dilated cardiomyopathy (DCM). In addition, we recruited five EAs with a region of subepicardial LV. Receiver operating characteristic fibrosis (EA-fibrosis). Cardiac magnetic resonance (CMR) imaging was performed at rest and during supine bicycle exercise. Invasive afterload measures were obtained to enable calculations of biventricular function relative to load (an estimate of contractility). In DCM and EA-fibrosis subjects there was diminished augmentation of LVEF (5 +/- 6% vs. 4 +/- 3% vs. 14 +/- 3%; P = 0.001) and contractility [LV end-systolic pressure-volume ratio, LVESPVR; 1.4 (1.3-1.6) vs. 1.5 (1.3-1.6) vs. 1.8 (1.7-2.7); P < 0.001] during exercise relative to EA healthy. Receiver-operator characteristic curves demonstrated that a cut-off value of 11.2% for DeltaLVEF differentiated DCM and EA-fibrosis patients from EA healthy [area under the curve (AUC) = 0.92, P < 0.001], whereas resting LVEF and VO2max were not predictive. The AUC value for LVESPVR ratio was similar to that of DeltaLVEF. Conclusions: Functional cardiac evaluation during exercise is a promising tool in differentiating healthy athletes with borderline LVEF from those with an underlying cardiomyopathy. Excellent exercise capacity does not exclude significant LV damage. PMID- 29590341 TI - Association between vaccination coverage decline and influenza incidence rise among Italian elderly. AB - After a peak of 68.3% during the 2005-06 season, influenza vaccine coverage among Italian elderly showed an unprecedented, prolonged decline. According to the National surveillance network, the vaccination coverage was <=50% during two of the last three seasons (2014-17). In parallel, influenza-like illness (ILI) rates increased from 2.71% in the triennium 2005-08, to 4.24% in the last triennium. A significant association was found between ILI rise and vaccine coverage decline (P = 0.036), and according to a conservative estimation, each 1% increase in coverage may prevent >=2690 ILI cases among the elderly. A reinforcement of influenza immunization policies is strongly needed in Italy. PMID- 29590343 TI - Expanding the Use of Primaquine for the Radical Cure of Plasmodium vivax. PMID- 29590344 TI - Ethno-cultural origins, health beliefs and mothers' behavior regarding infant vaccinations in Israel. AB - To compare the health beliefs and infant vaccination behavior of mothers of four different ethno-cultural backgrounds: Israeli-born Jewish and Arab-Bedouin and immigrants from the Former Soviet Union and Ethiopia; to examine the associations between initial and subsequent infant vaccination behaviors of mothers and to identify predictors of vaccination behaviors. A comparative cross-sectional study was conducted in selected community neighborhoods. A quota sample included 100 mothers with infants aged 18-24 months (N = 400) from each of the four ethno cultural groups. Data were collected through questionnaires and examination of the infant vaccination cards. Both groups of immigrant mothers had the lowest adherence to the recommended vaccination regime. Our findings indicate that maternal behaviors regarding infant vaccinations were determined mainly by the behavior at the previous recommended vaccination stage. Different ethno-cultural groups presented different sociodemographic predictors of vaccination behaviors. These predictors only affected the vaccinations at the early stage of 2 months. Policy makers should be aware that mother's vaccination behaviors vary according to ethno-cultural groups to establish culturally tailored intervention programs. PMID- 29590342 TI - Protein synthesis levels are increased in a subset of individuals with fragile X syndrome. AB - Fragile X syndrome (FXS) is a monogenic form of intellectual disability and autism spectrum disorder caused by the absence of the fragile X mental retardation protein (FMRP). In biological models for the disease, this leads to upregulated mRNA translation and as a consequence, deficits in synaptic architecture and plasticity. Preclinical studies revealed that pharmacological interventions restore those deficits, which are thought to mediate the FXS cognitive and behavioral symptoms. Here, we characterized the de novo rate of protein synthesis in patients with FXS and their relationship with clinical severity. We measured the rate of protein synthesis in fibroblasts derived from 32 individuals with FXS and from 17 controls as well as in fibroblasts and primary neurons of 27 Fmr1 KO mice and 20 controls. Here, we show that levels of protein synthesis are increased in fibroblasts of individuals with FXS and Fmr1 KO mice. However, this cellular phenotype displays a broad distribution and a proportion of fragile X individuals and Fmr1 KO mice do not show increased levels of protein synthesis, having measures in the normal range. Because the same Fmr1 KO animal measures in fibroblasts predict those in neurons we suggest the validity of this peripheral biomarker. Our study offers a potential explanation for the comprehensive drug development program undertaken thus far yielding negative results and suggests that a significant proportion, but not all individuals with FXS, may benefit from the reduction of excessive levels of protein synthesis. PMID- 29590345 TI - Proactive Infliximab Monitoring Following Reactive Testing is Associated With Better Clinical Outcomes Than Reactive Testing Alone in Patients With Inflammatory Bowel Disease. AB - Background and Aims: Reactive testing has emerged as the new standard of care for managing loss of response to infliximab in inflammatory bowel disease [IBD]. Recent data suggest that proactive infliximab monitoring is associated with better therapeutic outcomes in IBD. Nevertheless, there are no data regarding the clinical utility of proactive infliximab monitoring after first reactive testing. We aimed to evaluate long-term outcomes of proactive infliximab monitoring following reactive testing compared with reactive testing alone in patients with IBD. Methods: This was a retrospective multicenter cohort study of consecutive IBD patients on infliximab maintenance therapy receiving a first reactive testing between September 2006 and January 2015. Patients were divided into two groups; Group A [proactive infliximab monitoring after reactive testing] and Group B [reactive testing alone]. Patients were followed through December 2015. Time-to event analysis for treatment failure and IBD-related surgery and hospitalization was performed. Treatment failure was defined as drug discontinuation due to either loss of response or serious adverse event. Results: The study population consisted of 102 [n = 70, 69% with CD] patients [Group A, n = 33 and Group B, n = 69] who were followed for (median, interquartile range [IQR]) 2.7 [1.4-3.8] years. Multiple Cox regression analysis identified proactive following reactive TDM as independently associated with less treatment failure (hazard ratio [HR] 0.15; 95% confidence interval [CI] 0.05-0.51; p = 0.002) and fewer IBD-related hospitalizations [HR: 0.18; 95% CI 0.05-0.99; p = 0.007]. Conclusions: This study showed that proactive infliximab monitoring following reactive testing was associated with greater drug persistence and fewer IBD-related hospitalizations than reactive testing alone.

PMID- 29590347 TI - Association of Vitamin D deficiency with peripheral arterial disease: a meta analysis of literature studies. AB - Context: Vitamin D deficiency patients have an increased cardiovascular (CV) morbidity and mortality. Contrasting data are available about the association between peripheral arterial disease (PAD) and Vitamin D status. Objective: To perform a meta-analysis of studies evaluating the association between Vitamin D status and PAD. Data sources: Studies were systematically searched in the PubMed, Web of Science, Scopus and EMBASE databases. Results: Ten studies with data on Vitamin D levels in 2,079 PAD patients and 18,233 non-PAD controls and 6 studies on the prevalence of PAD in 23,171 subjects with Vitamin D deficiency (<20 ng/ml), 48,311 subjects with Vitamin D insufficiency (20-30 ng/ml) and 27,910 with normal Vitamin D levels (>30 ng/ml) were included. Compared to controls, PAD patients showed significantly lower Vitamin D levels (MD: -2.24 ng/ml; 95%CI: 3.38, -1.10; p<0.001, I2=86.5%; p<0.001). Moreover, a higher prevalence of PAD was found both in subjects with Vitamin D insufficiency (OR: 1.098, 95%CI: 1.010 1.195, p=0.029, I2: 0%, p=0,600) and in subjects with Vitamin D deficiency (OR: 1.484, 95%CI: 1.348-1.635, p<0.001, I2: 7.65%, p=0,367) compared with controls with normal Vitamin D levels. Sensitivity analyses and the analysis of data on the cumulative risk of PAD according to Vitamin D levels derived from multivariate analysis consistently confirmed results. Conclusions: PAD patients have lower vitamin D levels than controls and both Vitamin D deficiency and Vitamin D insufficiency are significantly associated with PAD. Reduced Vitamin D levels might represent an independent risk factor for PAD and, in turn, for CV events. PMID- 29590348 TI - Improving quality care for diabetes in the community: What do Cypriot patients want? AB - Objective: To measure patient preferences for their diabetic care in community setting. Design: Discrete-choice survey. Setting: Community setting (primary physician and hospital sites) in Cyprus. Participants: Diabetic patients attending community sites. Main Outcome Measure(s): Patient preferences, to estimate which components of quality healthcare service people value, their relative importance but also the potential shift to shared decision-making (SDM). Results: Older respondents with experience of the private sector already received SDM (managing their care and choosing their treatments; detailed and accurate information, continuity of care; compassion for their personal situation) from their primary care physician with waiting time shorter than 1 h. They valued their 'current' option and they did not want to change it with other services. Younger people from the public sector valued a change in policy and wanted to move from their 'current' to alternative diabetic care services where the waiting times were shorter, they could not only manage their care but also choose their treatments (together with receiving information, continuity of care and compassionate care). Individuals agreed with receiving multidisciplinary care from a team of healthcare providers but they mostly preferred being supported by their primary care physician. The pooled sample valued their 'current' option but they also supported policy changes that would implement SDM service for everybody. Conclusions: Diabetic patients value SDM and are willing to support a shift of practice to receive it not only in the private but also in the public sector. The forthcoming National Health Insurance Service would aim to address such developments as anticipated both in the European Troika's recommendations and the relevant laws. PMID- 29590349 TI - UK consumer perceptions of a novel till-receipt 'traffic-light' nutrition system. AB - Front-of-pack (FoP) traffic light nutrition labelling has been widely proposed as a tool to improve public health nutrition. Current evidence suggests that whilst consumers generally find them to be useful and an important source of information about a particular food or ingredient, this may have limited value in isolation when considering a person's overall nutritional intake. This study sought to examine UK consumers' use of existing FoP traffic light food labelling and ascertain public perception of a novel 'till-receipt' summary providing nutritional information about consumers entire shopping purchases. In total, 237 respondents completed an online questionnaire between May and June 2016. Almost two-thirds were female (n = 152, 64.1%) and the largest proportion of responses were received from those aged 25-32 years (n = 53, 22.4%) and 41-50 years (n = 53, 22.4%). About 83.5% of respondents suggested that they currently use traffic light information to inform their food purchases and 'health' was reported as the most important factor influencing food choice (42.2%; n = 100). Notably, 54.4% of respondents indicated that the novel till-receipt system could provide a solution to the potential limitations of existing FoP labelling and could help inform healthier food purchases. Our findings strengthen the existing evidence base to suggest that traffic light information is a useful tool to aid consumer food purchases. Moreover, our outcomes propose that consumers may benefit from a new receipt-based traffic light system which provides a more holistic summary of their entire food purchases. PMID- 29590350 TI - Usage and accuracy of medication data from nationwide health information exchange in Quebec, Canada. AB - Objective: (1) To describe the usage of medication data from the Health Information Exchange (HIE) at the health care system level in the province of Quebec; (2) To assess the accuracy of the medication list obtained from the HIE. Methods: A descriptive study was conducted utilizing usage data obtained from the Ministry of Health at the individual provider level from January 1 to December 31, 2015. Usage patterns by role, type of site, and tool used to access the HIE were investigated. The list of medications of 111 high risk patients arriving at the emergency department of an academic healthcare center was obtained from the HIE and compared with the list obtained through the medication reconciliation process. Results: There were 31 022 distinct users accessing the HIE 11 085 653 times in 2015. The vast majority of pharmacists and general practitioners accessed it, compared to a minority of specialists and nurses. The top 1% of users was responsible of 19% of access. Also, 63% of the access was made using the Viewer application, while using a certified electronic medical record application seemed to facilitate usage. Among 111 patients, 71 (64%) had at least one discrepancy between the medication list obtained from the HIE and the reference list. Conclusions: Early adopters were mostly in primary care settings, and were accessing it more frequently when using a certified electronic medical record. Further work is needed to investigate how to resolve accuracy issues with the medication list and how certain tools provide different features. PMID- 29590351 TI - Laboratory and Field Evaluation of the Entomopathogenic Fungus Beauveria bassiana (Deuteromycotina: Hyphomycetes) for Population Management of Spruce Beetle, Dendroctonus rufipennis (Coleoptera: Scolytinae), in Felled Trees and Factors Limiting Pathogen Success. AB - An isolate of the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill. (Deuteromycotina: Hyphomycetes) was tested for its ability to reduce survival and reproduction of spruce beetle, Dendroctonus rufipennis (Kirby) (Coleoptera: Scolytinae), under laboratory and field conditions. Conidial suspension applied directly to adults or to filter papers that adults contacted had a median survival time of 3-4 d in laboratory assays and beetles died more rapidly when exposed to conidial suspension than when treated with surfactant solution only. In the field, conidial suspension was applied to the surface of felled and pheromone-baited Engelmann spruce (Picea engelmannii) trees using a backpack sprayer. Mortality of colonizing parent beetles (F0), reproduction (abundance of F1 offspring in logs), and emergence of F1 beetles from logs was compared between treated and nontreated logs. Application of spore suspension increased mortality of F0 adults by 36% on average. Total F1 reproduction was reduced by 17% and emergence from logs was reduced by 13% in treated logs, but considerable variability in reproduction and emergence was observed. Viable spores were re isolated from treated logs up to 90 d after application, indicating that spores are capable of long-term persistence on the tree bole microhabitat. Subsequent in vitro tests revealed that temperatures below 15 degrees C and exposure to spruce monoterpenes likely limit performance of B. bassiana under field conditions, but exposure to low-intensity light or interactions with spruce beetle symbiotic fungi were not strongly inhibitory. It is concluded that matching environmental tolerances of biocontrol fungi to field conditions can likely improve their usefulness for control of spruce beetle in windthrown trees.

AB - Unhealthy eating and low levels of physical activity are major health risks, especially for older adults and people with a low socioeconomic status. The aim of this article is to describe the development of a community-based intervention aimed at promoting physical activity and healthy eating among people aged 55 years and over, in a socioeconomically disadvantaged community. The Intervention Mapping protocol was used to develop the intervention. We conducted a literature search, consultation with community partners and inhabitants, and a quantitative study, in order to obtain insight into the determinants of the target population and to identify appropriate theory-based methods and practical strategies for behavioural change. An assessment was performed of the problem with respect to health behaviour and the underlying determinants. Findings were translated into program, performance and change objectives which specify determinants related to behavioural change. Theory-based methods and practical applications were selected, resulting in a plan for adoption and implementation. The intervention included a local media campaign, social environmental approaches and physical environmental activities in the community, with an intermediating role for inhabitants and health professionals in the promotion of the campaign. An evaluation plan was produced to evaluate the effectiveness of the intervention. The Intervention Mapping protocol was a helpful instrument in developing a feasible, theory and evidence-based intervention tailored to a specific target population in the area of health promotion. The systematic and structured approach provided insight into the relationship between the objectives, methods and strategies used to develop the comprehensive intervention.

AB - Objective: The objective of this study was to evaluate the effectiveness of two automated medication systems in reducing medication administration errors. Design: The study was a controlled before-and-after study and included three observation periods with collection of data during a 3-week period as initial baseline and two subsequent follow-up periods at 10 and 20 months. Setting: The study was conducted in two Danish acute medical units. Interventions: Two automated medication systems were implemented: (i) a complex automated medication system (cAMS) consisting of an automated dispensing cabinet, automated unit-dose dispensing and barcode medication administration (BCMA) and (ii) a non-patient specific automated medication system (npsAMS) consisting of automated unit-dose dispensing and BCMA. Main outcome measure: The occurrence of administration errors and sub-types; procedural and clinical errors were observed. The proportion of errors was calculated by dividing the number of doses with one or more errors with the number of opportunities for errors. Difference-in-difference analysis using logistic regression was used to assess changes in proportion of errors. Results: Compared with control, the cAMS reduced the overall risk of administration errors in the intervention unit, (odds ratio (OR) 0.53; 95% confidence interval (CI) 0.27-0.90) and procedural errors were significantly reduced as well (OR 0.44; 95% CI 0.126-0.94). The npsAMS effectively reduced the clinical errors in the intervention ward (OR 0.38; 95% CI 0.15-0.96). Conclusions: In line with previous research, this study found that technological interventions in the medication administration process could reduce the occurrence of medication errors.

AB - Background: Antibiotic stewardship programs improve clinical outcomes and patient safety and help combat antibiotic resistance. Specific guidance on resources needed to structure stewardship programs is lacking. This manuscript describes results of a survey of US stewardship programs and resultant recommendations regarding potential staffing structures in the acute care setting. Methods: A cross-sectional survey of members of 3 infectious diseases subspecialty societies actively involved in antibiotic stewardship was conducted. Survey responses were analyzed with descriptive statistics. Logistic regression models were used to investigate the relationship between stewardship program staffing levels and self reported effectiveness and to determine which strategies mediate effectiveness. Results: Two-hundred forty-four respondents from a variety of acute care settings completed the survey. Prior authorization for select antibiotics, antibiotic reviews with prospective audit and feedback, and guideline development were common strategies. Eighty-five percent of surveyed programs demonstrated effectiveness in at least 1 outcome in the prior 2 years. Each 0.50 increase in pharmacist and physician full-time equivalent (FTE) support predicted a 1.48-fold increase in the odds of demonstrating effectiveness. The effect was mediated by the ability to perform prospective audit and feedback. Most programs noted significant barriers to success. Conclusions: Based on our survey's results, we propose an FTE-to-bed ratio that can be used as a starting point to guide discussions regarding necessary resources for antibiotic stewardship programs with executive leadership. Prospective audit and feedback should be the cornerstone of stewardship programs, and both physician leadership and pharmacists with expertise in stewardship are crucial for success.

AB - Objective: To assess the adequacy of antenatal care (ANC) and its association with pregnancy outcomes using an approach that includes adequacy of both utilization and content. Design: Retrospective cohort study. Setting and Participants: Women attending ANC at public-funded primary health clinics where data were extracted from individual records. Methods: Adequacy of utilization assessment was based on the concept of Adequacy of Prenatal Care Utilization index; adequacy of content assessed the recommended routine care received by the women according to local guidelines. Association between adequacy and pregnancy outcomes was examined using binary logistic regression. Main Outcome Measures: Pregnancy outcomes included preterm birth and low birth weight. Results: Sixty three percent of women showed higher than recommended ANC utilization; 52% had <80% of recommended routine care content. Although not statistically significant, the odds of preterm birth was lower among women with adequate level of utilization compared with inadequate (adjusted odds ratios (aOR) = 2.34, 95% confidence interval (CI) 0.45-12.16) and intensive levels (aOR = 3.27, 95% CI 0.73-14.60). Regarding adequacy of content, women who received inadequate level of care content were associated with higher prevalence of preterm birth (aOR = 3.69, 95% CI 1.60-8.55). Conclusion: The study shows inadequate content is associated with higher prevalence of preterm birth and suggests that inadequate utilization increases the risk of preterm birth. It demonstrates the relevance of using both utilization and content assessment in evaluating quality of ANC. Further studies are encouraged to review the methods used. PMID- 29590357 TI - Hip Fractures in People Older Than 95 Years: Are Patients Without Age-Associated Illnesses Different? AB - Background: Patients older than 95 years of age can be categorized according to three morbidity profiles: escapers, delayers, and survivors. The aim of this study was to describe the baseline characteristics, in-hospital outcomes, and cumulative mortality of extremely elderly patients admitted with hip fractures and to examine whether there were differences between patients without age related illnesses (escapers) and others in the same age group (survivors when age associated illnesses were diagnosed before the age of 80, delayers when these illnesses appeared after the age of 80). Methods: A retrospective review of clinical and outcome data of all patients older than 95 years of age admitted with hip fractures. Results: Two hundred patients older than 95 years were admitted with hip fractures between December 2009 and September 2015. Eighty-six per cent of patients had at least one in-hospital complication. In-hospital mortality was 12.5 per cent; cumulative mortality rates at 30 days, 3 months, and 1 year were 20.3, 30.8, and 50.5 per cent, respectively. There were 15 (7.5%) escaper patients. Compared with other patients with age-related illnesses, they took fewer drugs, had lower Charlson scores, a higher Barthel index score, shorter length of hospital stay, less delay in surgery, and more often required discharge to an in-patient rehabilitation facility. No differences in cumulative mortality were noted. Conclusions: Escaper patients had better baseline characteristics, shorter length of hospital stay, and delay in surgery. Nevertheless, their in-hospital and cumulative mortality rates were similar to those of other patients older than 95 years. PMID- 29590358 TI - Gene Expression Classifier vs Targeted Next-Generation Sequencing in the Management of Indeterminate Thyroid Nodules. AB - Context: Molecular testing has reduced the need for diagnostic hemithyroidectomy for indeterminate thyroid nodules. No studies have directly compared molecular testing techniques. Objective: Compare the diagnostic performance of Afirma Gene Expression Classifier (GEC) with that of ThyroSeq v2 next-generation sequencing assay. Design: Parallel randomized trial, monthly block randomization of patients with Bethesda III/IV cytology to GEC or ThyroSeq v2. Setting: University of California, Los Angeles. Participants: Patients who underwent thyroid biopsy (April 2016 to June 2017). Intervention: Testing with GEC or ThyroSeq v2. Main Outcome Measure: Molecular test performance. Results: Of 1372 thyroid nodules, 176 (13%) had indeterminate cytology and 149 of 157 eligible indeterminate nodules (95%) were included in the study. Of nodules tested with GEC, 49% were suspicious, 43% were benign, and 9% were insufficient. Of nodules tested with ThyroSeq v2, 19% were mutation positive, 77% were mutation negative, and 4% were insufficient. The specificities of GEC and ThyroSeq v2 were 66% and 91%, respectively (P = 0.002); the positive predictive values of GEC and ThyroSeq v2 were 39% and 57%, respectively. Diagnostic hemithyroidectomy was avoided in 28 patients tested with GEC (39%) and 49 patients tested with ThyroSeq v2 (62%). Surveillance ultrasonography was available for 46 nodules (45 remained stable). Conclusions: ThyroSeq v2 had higher specificity than Afirma GEC and allowed more patients to avoid surgery. Long-term surveillance is necessary to assess the false-negative rate of these particular molecular tests. Further studies are required for comparison with other available molecular diagnostics and for newer tests as they are developed.

PMID- 29590360 TI - Metabolites of endophytic fungi from Australian native plants as potential anticancer agents. AB - Interest in endophytes as natural sources for new medicines was inspired by the discovery of paclitaxel-producing endophytic fungi. This study investigated the anti-cancer activity of extracts of endophytes isolated from two Australian plants, Eremophila longifolia (EL) and Eremophila maculata (EM). Endophytes were isolated from surface-sterilised leaf tissue, grown as pure cultures and identified by sequencing of Internal Transcribed Spacer (ITS) regions of the ribosomal DNA. To determine cytotoxicity, two leukaemic (MOLT-4, T-cell leukaemia; PreB-697, Pre-B leukaemia), a lung cancer cell line (A549) and a normal human fibroblast cell line were treated with endophyte extracts to assess cytotoxicity in relation to alternariol monomethyl ether (AME) and alternariol (AOH). Endophyte extracts that showed cell cytotoxicity were analysed by UV-HPLC to determine the metabolites. Pure AME and AOH, three extracts form Alternaria sp. (EM-6, EM-7 and EM-9) and one from Preussia minima (EL-14) were cytotoxic to the cancer cell lines. All cytotoxic endophytes contained AME and AOH, the most cytotoxic endophyte EM-6 also contained two unique peaks. These data indicate that these four endophyte extracts may have anti-cancer properties due to the presence of AME and AOH; however, the unique compounds found in the EM-6 extract may be exclusively cytotoxic and warrant further investigation. PMID- 29590361 TI - Cell type discovery using single-cell transcriptomics: implications for ontological representation. AB - Cells are fundamental function units of multicellular organisms, with different cell types playing distinct physiological roles in the body. The recent advent of single-cell transcriptional profiling using RNA sequencing is producing 'big data', enabling the identification of novel human cell types at an unprecedented rate. In this review, we summarize recent work characterizing cell types in the human central nervous and immune systems using single-cell and single-nuclei RNA sequencing, and discuss the implications that these discoveries are having on the representation of cell types in the reference Cell Ontology (CL). We propose a method, based on random forest machine learning, for identifying sets of necessary and sufficient marker genes, which can be used to assemble consistent and reproducible cell type definitions for incorporation into the CL. The representation of defined cell type classes and their relationships in the CL using this strategy will make the cell type classes being identified by high throughput/high-content technologies findable, accessible, interoperable and reusable (FAIR), allowing the CL to serve as a reference knowledgebase of information about the role that distinct cellular phenotypes play in human health and disease. PMID- 29590362 TI - Frailty as a predictor of mortality and hospital services use in older adults: a cluster analysis in a cohort study. AB - Background: Lowering mortality and hospitalization of older adults is one of the main goals of public health to improve both health systems' sustainability and older adults' quality of life. The aim of this study is to identify the determinants associated with mortality and the use of hospital services in the population older than 64 years of age. Methods: A randomized sample from the population of the Lazio region (Italy) above the age of 64 was enrolled in 2014 by the administration of a questionnaire to assess frailty; the rates of use of hospital services and mortality in the year following the enrolment have been retrieved by the regional database. Univariable and multivariable analyses addressed the association of health status, social and economic variables with health outcomes. Results: One thousand two hundred and eighty persons were recruited; 52 deaths were reported at 1 year of follow-up (robust 1.8%, frail 10.1% and very frail 19.1%, P < 0.001). The mean rate of use of hospital services was 692.2 per 1000 observation/year (robust 589.5, frail 1191.1 and very frail 848.4, P < 0.001). In the multivariate analysis, the higher rate of use of hospital services was independently associated with functional status, social support, psychological/psychiatric discomfort, availability of home care services and physical health. Conclusions: Frailty, as a multidimensional issue, is also a strong predictor of survival in the short term. The use of the hospital services by older adults is associated mainly with functional status, social resources, psycho-physical status and health service organization factors. PMID- 29590363 TI - The intergenerational consequences of war: anxiety, depression, suicidality, and mental health among the children of war veterans. AB - Background: The long-term effects of military deployment on the mental health of war veterans have been investigated extensively, but few studies have examined the long-term impact of parental deployment on children's mental health. Methods: Using a retrospective, multigenerational survey and propensity score analysis to adjust for selection effects and endogeneity bias, we investigated the impact of parental deployment on the mental health of the adult children of Australian veterans of the Vietnam War. We analysed data from 1966 adult men (35%) and women (65%) whose fathers (N = 1418) were selected at random from the population of surviving men who served in the Australian army during the Vietnam War (1962-75). Mean age of respondents was 37. The main outcome measures were self-reported diagnosis or treatment for anxiety and depression (i.e. lifetime and previous 12 months), suicidality based on Psychiatric Symptom Frequency Scale, and current mental health as measured by the Mental Health Inventory of the SF-36. The key independent variable was whether their fathers were deployed to the Vietnam War. Results: Almost 40 years after the war, the adult children of deployed veterans were more likely to have been diagnosed with anxiety [odds ratio (OR) = 1.54, confidence interval (CI) = 1.04, 2.28] and depression (OR = 1.77, CI = 1.03, 3.05), to have had thoughts of suicide and self-harm (OR = 2.39, CI = 1.57, 3.65) and to have made suicidal plans (OR = 3.52, CI = 1.40, 8.85) than the offspring of comparable, non-deployed army veterans. They also reported poorer current mental health (Coefficient = -5.08, CI = -6.60 - -3.56). Conclusions: The results imply that there are significant and enduring adverse effects of parental deployment on the mental health of children in military families, and provide some insight into the potential long-term impacts of recent military engagements in Afghanistan and Iraq. PMID- 29590364 TI - When is quitting an escape? How different job demands affect physical and mental health outcomes of retirement. AB - Background: The demographic aging of societies and the need to adapt to this trend makes it important to gain insight into the way retirement affects different forms of health, and factors that influence this relationship. Pre retirement job characteristics have only rarely been included in this type of research. Methods: The regressor variable method is applied to two waves (4 and 5) of data from the Survey of Health Ageing and Retirement in Europe, a multi national prospective cohort study. The final sample consists of 9092 people aged 50-70 at wave 4, of whom 1257 retired voluntarily. Health is assessed through the presence of physical health problems, general self-rated health and the EURO-D scale for depressive symptoms. Results: The findings indicate that retirement from jobs with high physical demands leads to a relative improvement in general self-rated health compared with those who remain at work. Retirement from a psychologically demanding job is associated with less depressive symptoms. No effects are found for health measured as the presence of physical health problems. Conclusion: Different types of measures for health yield different results for outcomes of retirement; pre-retirement job demands play an important role in how retirement affects health; physical demands seem primarily related to physical health benefits, psychological demands seem primarily related to mental health benefits. PMID- 29590365 TI - A quality improvement project to increase self-administration of medicines in an acute hospital. AB - Quality problem or issue: A patient survey found significantly fewer patients reported they had self-administered their medicines while in hospital (20% of 100 patients) than reported that they would like to (44% of 100). We aimed to make self-administration more easily available to patients who wanted it. Initial assessment: We conducted a failure, modes and effects analysis, collected baseline data on four wards and carried out observations. Choice of solution: Our initial assessment suggested that the main areas we should focus on were raising patient awareness of self-administration, changing the patient assessment process and creating a storage solution for medicines being self-administered. We developed new patient information leaflets and posters and a doctor's assessment form using Plan-Do-Study-Act cycles. We developed initial designs for a storage solution. Implementation: We piloted the new materials on three wards; the fourth withdrew due to staff shortages. Evaluation: Following collection of baseline data, we continued to collect weekly data. We found that the proportion of patients who wished to self-administer who reported that they were able to do so, significantly increased from 41% (of 155 patients) to 66% (of 118 patients) during the study, despite a period when the hospital was over capacity. Lessons learned: Raising and maintaining healthcare professionals' awareness of self administration can greatly increase the proportion of patients who wish to self administer who actually do so. Healthcare professionals prefer multi-disciplinary input into the assessment process. PMID- 29590367 TI - Selective visceral perfusion improves renal flow and hepatic function in neonatal aortic arch repair. AB - OBJECTIVES: The aortic arch repair in the neonatal period is a complex procedure with significant morbidity. We define a useful double-perfusion technique and its effect on the function of abdominal organs in the postoperative course. METHODS: Nine patients with double perfusion (Group 1) were compared with 14 patients with antegrade cerebral perfusion (Group 2). The objective was to discern the incidence of postoperative acute kidney injury and impaired hepatic function, as well as tissue perfusion and myocardial function parameters. Mechanical ventilation time, postoperative length of stay and 30-day mortality were measured. We excluded patients with extracorporeal membrane oxygenation, early mortality (<72 h) and preoperative renal or hepatic insufficiency. RESULTS: Nine (39%) patients developed postoperative acute kidney injury, with 22% (n = 2) in Group 1 and 50% (n = 7) in Group 2 (P = 0.183). A higher urine output was observed during the first 24 h for Group 1 (P = 0.032). Eleven patients developed impaired hepatic function in the immediate postoperative period: 2 (18.2%) in Group 1 and 9 (81.8%) in Group 2 (P = 0.04). The international normalized ratio (P = 0.006-0.031) and prothrombin time (P = 0.007-P = 0.016) were significantly lower in the double-perfusion group during the first 72 h. Significant difference was observed in lactate levels in the first 72 h (P = 0.001-0.009). There was no postoperative mortality in either group. CONCLUSIONS: Selective visceral perfusion is a safe procedure that provides a better urine output, hepatic function and tissue perfusion. This technique allows for the repair of complex aortic arch anomalies in neonates without deep hypothermic circulatory arrest. PMID- 29590366 TI - 'Drug adherence levels are falling down again': health worker perceptions of women's service utilization before and after integration of HIV/AIDS services into general care in India. AB - Integrated models of HIV/AIDS service delivery are believed to have advantages over stand-alone models of care from health planners' and providers' perspectives. Integration models differ, yet there is little information about the influence of differing models on workers' beliefs about models' efficacy. Here, we examine the effect of integration of HIV care into the general health system in India. In 2014, India replaced its stand-alone model of HIV service delivery-Community Care Centers (CCCs)-with a purported integrated model that delivers HIV medical services at general hospitals and HIV psychosocial services at nearby Care and Support Centers (CSCs). We examine 15 health workers' perceptions of how change from the earlier stand-alone model to the current model impacted women's care in a district in Uttar Pradesh, India. Results indicate that (1) Women's antiretroviral (ART) adherence and utilization of psychosocial support service for HIV/AIDS suffered when services were not provided at one site; (2) Provision of inpatient care in the CCC model offered women living in poverty personal safety in accessing HIV health services and promoted chances of competent ART usage and repeat service utilization; and (3) Although integration of HIV services with the general health system was perceived to improve patient anonymity and decrease chances of HIV-related stigma and discrimination, resource shortages continued to plague the integrated system while shifting costs of time and money to the patients. Findings suggest that integration efforts need to consider the context of service provision and the gendered nature of access to HIV care. PMID- 29590368 TI - Developing patient safety system using WHO tool in hospitals in Oman. AB - Objective: Oman is progressively implementing the Patient Safety Friendly Hospital Initiative (PSFHI), a tool formulated by the World Health Organization (WHO) to achieve optimal patient safety in hospitals. This paper describes its implementation in selected government and private hospitals in Oman and analyses the performance of four hospitals whose implementations of PSFHI were assessed by WHO. Design: The PSFHI initiative was launched in 11 hospitals in Oman during 2016. The enrolled hospitals implemented a 1-year plan composed of several steps such as formation of steering committees, working groups, full orientation about the standards, training of staff, documents development and community involvement. One year later, four hospitals which were the earliest to join the initiative were subjected to WHO assessment. Setting: Secondary level government and private hospitals. Intervention(s): The WHO-PSFHI standards. Main Outcome Measure: Hospitals' adherence to the standards. Results: Three of the four hospitals (one government and two private) scored level two. One government hospital scored level three, earning it the distinction of being the first hospital in the Eastern Mediterranean Region to reach level three in the very first assessment. Conclusions: Implementation of PSFHI in selected hospitals of Oman had successful outcomes in improving patient's safety. PMID- 29590369 TI - Rotation of the outflow tracts.

PMID- 29590370 TI - KPC-2 carbapenemase-producing Pseudomonas aeruginosa reaching Germany. AB - Background: Antimicrobial resistance due to carbapenemase expression poses a worldwide threat in healthcare. Inter-genus exchange of genetic information is of utmost importance in this context. Objectives: Here, to the best of our knowledge, we describe the first detection and characterization of a KPC-2 producing Pseudomonas aeruginosa in Germany. Methods: Characterization of the isolate was performed using MALDI-TOF MS, automated microdilution and MLST. Carbapenemase detection was performed using phenotypic and genotypic assays. The blaKPC-2-carrying plasmid was transformed into Escherichia coli NEB(r) 10-beta. The purified plasmid DNA was sequenced using the Illumina technique. Results: The isolate expressed ST235 and was resistant to carbapenems. Antimicrobial susceptibility testing revealed colistin to be the only antimicrobial agent active in vitro. The blaKPC-2 gene was located on a replicon type lncHI1 plasmid as part of Tn4401. Conclusions: The first detection (to the best of our knowledge) of plasmid-encoded KPC-2 in P. aeruginosa in Germany may point to a currently underestimated spread of carbapenemases among clinically relevant Gram negative bacteria. Here, to the best of our knowledge, we also provide the first report of blaKPC-2 associated with the IncHI1 plasmid. PMID- 29590371 TI - Somatostatin Analogs and Glucose Metabolism in Acromegaly: A Meta-analysis of Prospective Interventional Studies. AB - Introduction: Somatostatin analogs (SSAs) effectivelycontrol growth hormone secretion in first and second line treatmentof acromegaly. Their effect onglucose metabolism is still debated. Aim: to address the following questions: 1) Do SSAs affect fasting plasma glucose (FPG), fasting plasma insulin (FPI), glycosylated hemoglobin (HbA1c), glucose load (2h-OGTT), HOMA-I, HOMA-beta, triglycerides (TGD), weight (W) or body mass index (BMI)? 2) Do lanreotide (LAN) and octreotide LAR (OCT) affect metabolism differently? 3)Does their effect depend on disease control? Methods: We performed a meta-analysis of prospective interventional trialstreating acromegaly with SSAs. Inclusion criteria: all studies reporting glyco-metabolic outcomes before and after SSAs with a minimum 6-month follow-up. Results: The inclusion criteria were met by 47 studies treating 1297 subjects (631 F). SSA treatment effectively lowered FPI (effect size [ES] -6.67 mU/L, 95%CI: -8.38 to -4.95mU/L; p<0.001), HOMA-I (ES -1.57, CI: -2.42 to -0.72; p<0.001), HOMA-beta (ES -47.45, CI: -73.15 to -21.76; p<0.001) and TGD (ES -0.37 mmol/L, CI: -0.47 to -0.27 mmol/L; p<0.001). SSAs worsened 2h-OGTT (ES 0.59 mmol/L, CI: 0.05 to 1.13 mmol/L; p=0.032), but not FPG. A mild but significant increase in HbA1c (ES 0.12%, CI: 0.00to 0.25%; p=0.044) was found in OCT treated subjects. Conclusions: SSA treatment in acromegaly patients-while improving disease control- reduces insulin levels, increases after load glucose and, ultimately, increases HbA1c levels without affecting FPG. The findings suggest that clinicians treating acromegaly with SSAs should consider targeting post prandial glucose. PMID- 29590372 TI - Expression Profiles and Functional Characterization of Two Odorant-Binding Proteins From the Apple Buprestid Beetle Agrilus mali (Coleoptera: Buprestidae). AB - The apple buprestid beetle, Agrilus mali Matsumura (Coleoptera: Buprestidae), can respond to various volatiles, but the underlying mechanism of odorant perception for this insect is poorly understood. Here, we cloned A. mali's odorant-binding proteins 3 (AmalOBP3) and 8 (AmalOBP8) and characterized their expression patterns and binding profiles. Sequence and phylogenetic analyses showed that AmalOBP3 and AmalOBP8 were distributed in the classic and minus-C OBP subfamily, respectively. AmalOBP3 was specifically and abundantly expressed in antennae of both sexes. AmalOBP8 displayed high transcript levels in antennae of both sexes, abdomens of males, and wings of both sexes. Both AmalOBPs exhibited much higher expression in male antennae than in female antennae, suggesting that they could be important in perception of male-specific olfactory cues (e.g., some sex pheromones). Out of the 40 odorant ligands tested, AmalOBP3 and AmalOBP8 bound to 15 and 21 different odorants, respectively, indicating a distinct and selective binding profile for them. Both AmalOBPs seemed to have very strong binding affinity to aliphatic alcohols and aldehydes with 12 to 15 carbon atoms. Alcohols, esters, and terpenoids were more likely to be good ligands for both AmalOBPs than aldehydes and alkanes. Together with its broad expression in different tissues, strong binding with higher numbers of putative ligands for AmalOPB8 means that this protein can have more extensive functional roles in chemosensation of A. mali. Our results provide insights into the molecular basis of chemosensation in A. mali, as well as a basis for developing detection, monitoring, and management tools for this serious pest. PMID- 29590373 TI - Certification ISO 9001 in clinical ethics consultation for improving quality and safety in healthcare. AB - This paper refers to the quality management process of the Laboratory of Clinical Bioethics (LCB) of the University of Padua (Italy), which has obtained the quality certification to ISO 9001:2008, as a Clinical Ethics Support Service. Its activities consist mainly in clinical ethics consultations and training services, addressed to those who are called to decisions with ethical implications in the clinical setting, proposing a structured approach to identify and analyze the ethical issues that may loom in the relationships between health professionals and patients, and participating in their solution. The expected benefits of the application of ISO 9001 were mainly the following: to formalize the procedure adopted for clinical ethics consultation and training, to obtain a controlled management of documents, information and data, to ensure and demonstrate the quality of the provided activities and to make methods and organization publicly available. The main results which have been achieved with the 'quality management project' are summarized as follows: the enunciation of LCB Mission and Quality Policy; the drafting of the procedure by which clinical ethics consultation is provided; the formalization of members' skills and the adoption of relevant process and outcome indicators. Our experience may be useful in promoting accountability for the quality of ethics consultation services. We consider the certification process as a tool for transparent and reliable management of one of the most critical tasks in the current context of healthcare, motivating similar facilities to undertake similar pathways, with the aim to provide quality control on their activities.

PMID- 29590375 TI - Ethnicity, obesity and the prevalence of impaired glucose tolerance and type 2 diabetes in PCOS: a systematic review and meta-regression. AB - BACKGROUND: Our prior meta-analyses demonstrated an increased prevalence of impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) with polycystic ovary syndrome (PCOS), but with substantial clinical heterogeneity. OBJECTIVE AND RATIONALE: We aimed to update our previous review to quantify the prevalence of IGT and T2DM in PCOS with only quality studies (good and fair quality). We also aimed to examine the contribution of parameters including ethnicity, obesity and method of diagnosing T2DM in explaining the observed heterogeneity in IGT and T2DM prevalence in PCOS. SEARCH METHODS: We conducted a literature search (MEDLINE, CINAHL, EMBASE, clinical trial registries and hand searching) up to June 2016 to identify studies reporting the prevalence of dysglycemia (IGT and T2DM) in women with and without PCOS. We included studies where women with PCOS (defined according to original National Institute of Health) were compared to women without PCOS for the end-points of the prevalence of IGT or T2DM. We excluded case reports, case series, editorials, and narrative reviews. Studies where PCOS was diagnosed by self-report, or where IGT or T2DM were measured by fasting glucose, only were excluded. We assessed the methodological quality of the included studies using a priori criteria based on the Newcastle-Ottawa Scaling (NOS) for non-randomized studies. Data are presented as odds ratio (OR) (95% CI) with random-effects meta-analysis by Mantel-Haenszel methods. We assessed the contribution of demographic and clinical factors to heterogeneity using subgroup and meta-regression analysis. OUTCOMES: We reviewed 4530 studies and included 40 eligible studies in the final analysis. On meta analysis of quality studies, women with PCOS had an increased prevalence of IGT (OR = 3.26, 95% CI: 2.17-4.90) and T2DM (OR = 2.87, 95% CI: 1.44-5.72), which differed by ethnicity (for IGT, Asia: 5-fold, the Americas: 4-fold and Europe: 3 fold), was higher with obesity, and doubled among studies using self-report or administrative data for diagnosing diabetes. The ethnicity-related difference retained its significance for Asia and Europe in BMI-matched subgroups. Clear contributors to heterogeneity did not emerge in meta-regression. WIDER IMPLICATIONS: Our findings underscore the importance of PCOS as a cause of dysglycemia with a higher prevalence of IGT and T2DM. They support the relevance of ethnicity and obesity and emphasize the need for accurate diagnostic methods for diabetes. PROSPERO REGISTRATION NUMBER: CRD42017056524. PMID- 29590376 TI - Incidence of Nephrotoxicity Among Pediatric Patients Receiving Vancomycin With Either Piperacillin-Tazobactam or Cefepime: A Cohort Study. AB - Background: Recent studies in adults have found an incidence of acute kidney injury (AKI) in patients treated with a combination of vancomycin and piperacillin-tazobactam (TZP) that is greater than that expected with either medication alone. The purpose of this study was to determine whether combination therapy with vancomycin and TZP is associated with an incidence of AKI in pediatric patients higher than that in those on combination therapy with vancomycin and cefepime. Methods: We performed a retrospective single-center matched-cohort study of pediatric patients who received vancomycin in combination with TZP or cefepime between January 2015 and June 2016. The patients were matched according to chronic disease, age, sex, and number of concomitant nephrotoxic medications at the time of combination antibiotic therapy. The primary outcome was incidence of AKI. Secondary outcomes included differences between groups in time to AKI, resolution of AKI, and effect of vancomycin trough levels on the incidence of nephrotoxicity. Conditional logistic regression was used to compare categorical and continuous variables between treatment groups. Conditional Poisson regression was used to assess the association between AKI and treatment groups. Stratified log-rank tests and Cox proportional hazards models with shared frailty were used to compare the times to AKI according to treatment group. Results: Two hundred twenty-eight matched patients were included. AKI developed in 9 (7.9%) of 114 and 33 (28.9%) of 114 patients in the cefepime and TZP groups, respectively (P < .001). Type of combination therapy remained a significant predictor for AKI in multivariate conditional Poisson analysis in which adjustments were made for age, sex, use of concomitant nephrotoxins, and vancomycin dose (relative risk, 2.5 [95% confidence interval, 1.1-5.8]; P = .03). AKI developed almost 3 times sooner in the TZP group than in the cefepime group (hazard ratio, 2.9 [95% confidence interval, 1.3-6.1]; P = .006). Sensitivity analyses in which adjustment was made for antibiotic indication in addition to the aforementioned variables and excluding those with gastrointestinal infection revealed similar results. Conclusion: Among hospitalized children at our institution, combination therapy with vancomycin and TZP was associated with an incidence of AKI higher than that associated with vancomycin and cefepime.

AB - Background: Vitamin D deficiency (VDD) and vitamin D insufficiency (VDI) are highly prevalent in the world, but the vitamin D status of children in northeast China is seldom investigated. The aim of this study was to clarify the prevalence of VDD and VDI among children in the First Affiliated Hospital of Harbin Medical University in Heilongjiang province in China. Methods: We collected data from 9795 children who were outpatients aged 0-12 years who visited the First Affiliated Hospital of Harbin Medical University from September 2014 to August 2016. Serum 25-hydroxy vitamin D [25(OH)D] levels were determined by chemiluminescent immunoassay and categorized as <20, 20-30 and >30 ng/mL. Results: The highest mean level of serum 25(OH)D was found at the 1-3 years stage (31.14 ng/mL) and the lowest at 6-12 years stage (18.58 ng/mL). The mean serum 25(OH)D level among school girls (17.86 ng/mL) was lower than that of boys (19.12 ng/mL). The prevalence of vitamin D sufficiency during 2014 was only 17.2%, but increased to ~45% in 2016. Conclusions: The prevalence of VDD and insufficiency among children in the First Affiliated Hospital of Harbin Medical University is high, especially among children aged 6-12 years. PMID- 29590378 TI - Effect of Relaxation of Deltamethrin Pressure on Metabolic Resistance in a Pyrethroid-Resistant Aedes aegypti (Diptera: Culicidae) Strain Harboring Fixed P989P and G1016G kdr Alleles. AB - Mutation of the voltage-gated sodium channel genes or knockdown resistance (kdr) and metabolic resistance in Aedes aegypti (L.) (Diptera: Culicidae) are important resistance mechanisms against pyrethroids. The present study investigated the effect of relaxation of deltamethrin selection pressure on the level of mixed function oxidases (MFO), when the allele frequency of S989P+V1016G mutations is fixed in a resistant Ae. aegypti strain (UPK-R) from Chiang Mai, Thailand. The mosquitoes were divided into two groups, exposure and nonexposure groups, and maintained for 12 generations in an insectary room. Adults of the exposure group (F3 to F12) were treated with 0.05% deltamethrin-impregnated papers. The median lethal concentrations (LC50) of deltamethrin of larvae were determined by World Health Organization (WHO) bioassay. MFO activity was determined in F0 and F12. The results revealed that there was a decreasing trend of adult mortality rates in the exposure group over time. The larval LC50 values of the exposure group were gradually increased, whereas those of the nonexposure group were gradually decreased. The level of MFO activity in the nonexposure group (F12) was lower than the parent and exposure groups (F12) by 1.5 and 4-fold in the larvae, respectively, and 1.5 and 2.5-fold in the adult females, respectively. However, the frequency of P989+G1016 alleles in both groups was 100% up to F12 when the experiment ended. This study indicates that there was a significant but small reduction in the activity levels of MFOs when pyrethroid selection pressure is relaxed in this kdr strain of Ae. aegypti. PMID- 29590379 TI - Increased Plasma Proneurotensin Levels Identify NAFLD in Adults With and Without Type 2 Diabetes. AB - Context: Neurotensin (NT), an intestinal peptide released by fat ingestion, promotes lipid absorption; higher circulating NT levels are associated with type 2 diabetes (T2D), obesity, and cardiovascular disease. Whether NT is related to nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) has not been fully investigated. Objective: To study the relationship between plasma proneurotensin 1 to 117 (pro-NT), a stable fragment of the NT precursor hormone, and the presence/severity of NAFLD/NASH and to unravel correlates of increased pro-NT levels. Design/Setting/Participants: For this cross-sectional study, 60 obese individuals undergoing bariatric surgery for clinical purposes were recruited. The association between pro-NT and NAFLD was further investigated in 260 consecutive subjects referred to our outpatient clinics for metabolic evaluations, including liver ultrasonography. The study population underwent complete metabolic characterization; in the obese cohort, liver biopsies were performed during surgery. Main Outcome Measures: Plasma pro-NT levels in relation to NAFLD/NASH. Results: Obese subjects with biopsy-proven NAFLD (53%) had significantly higher plasma pro-NT than those without NAFLD (183.6 +/- 81.4 vs 86.7 +/- 56.8 pmol/L, P < 0.001). Greater pro-NT correlated with NAFLD presence (P < 0.001) and severity (P < 0.001), age, female sex, insulin resistance, and T2D. Higher pro-NT predicted NAFLD with an area under receiver operating characteristic curve of 0.836 [95% confidence interval (CI), 0.73 to 0.94; P < 0.001]. Belonging to the highest pro-NT quartile correlated with increased NAFLD risk (odds ratio, 2.62; 95% CI, 1.08 to 6.40) after adjustment for confounders. The association between higher pro-NT and NAFLD was confirmed in the second cohort independently from confounders. Conclusions: Increased plasma pro-NT levels identify the presence/severity of NAFLD; in dysmetabolic individuals, NT may specifically promote hepatic fat accumulation through mechanisms likely related to increased insulin resistance. PMID- 29590380 TI - Screening for Moral Injury: The Moral Injury Symptom Scale - Military Version Short Form. AB - Introduction: To develop a short form (SF) of the 45-item multidimensional Moral Injury Symptom Scale - Military Version (MISS-M) to use when screening for moral injury and monitoring treatment response in veterans and active duty military with PTSD. Methods: A total of 427 veterans and active duty military with PTSD symptoms were recruited from VA Medical Centers in Augusta, GA; Los Angeles, CA; Durham, NC; Houston, TX; and San Antonio, TX; and from Liberty University, Lynchburg, Virginia. The sample was randomly split in two. In the first half (n = 214), exploratory factor analysis identified the highest loading item on each of the 10 MISS scales (guilt, shame, moral concerns, loss of meaning, difficulty forgiving, loss of trust, self-condemnation, religious struggle, and loss of religious faith) to form the 10-item MISS-M-SF; confirmatory factor analysis was then performed to replicate results in the second half of the sample (n = 213). Internal reliability, test-retest reliability, and convergent, discriminant, and concurrent validity were examined in the overall sample. The study was approved by the institutional review boards and the Research & Development (R&D) Committees at Veterans Administration medical centers in Durham, Los Angeles, Augusta, Houston, and San Antonio, and the Liberty University and Duke University Medical Center institutional review boards. Findings: The 10-item MISS-M-SF had a median of 50 and a range of 12-91 (possible range 10-100). Over 70% scored a 9 or 10 (highest possible) on at least one item. Cronbach's alpha was 0.73 (95% CI 0.69-0.76), and test-retest reliability was 0.87 (95% CI 0.79-0.92). Convergent validity with the 45-item MISS-M was r = 0.92. Discriminant validity was demonstrated by relatively weak correlations with social, religious, and physical health constructs (r = 0.21-0.35), and concurrent validity was indicated by strong correlations with PTSD, depression, and anxiety symptoms (r = 0.54-0.58). Discussion: The MISS-M-SF is a reliable and valid measure of MI symptoms that can be used to screen for MI and monitor response to treatment in veterans and active duty military with PTSD. PMID- 29590382 TI - The impact of hot food takeaways near schools in the UK on childhood obesity: a systematic review of the evidence. AB - Background: Obesity is the greatest health issue for this generation; schools have improved food offered within their grounds. The built environment surrounding schools and pupils' journeys home have not received the same level of attention. This review identified papers on impacts of hot food takeaways surrounding schools in the UK. Methods: Methods were informed by the PRISMA (QUORUM) guidelines for systematic reviews. Searches were completed in 12 databases. Results: A total of 14 papers were included and quality assured before data extraction. Three descriptive themes were found; descriptions of hot food takeaway's geography and impacts concerning schools, strategic food policy and pupils reported food behaviour. Conclusions: Most included studies compared anthropometric measures with geographical location of hot food takeaways to find correlations between environment and childhood obesity. There was good evidence of more hot food takeaways in deprived areas and children who spend time in deprived neighbourhoods tend to eat more fast food and have higher BMIs. Few studies were able to quantify the correlation between school's environment and obesity amongst pupils. This lack of evidence is likely a factor of the studies' ability to identify the correlation rather than lack of a correlation between the two variables. PMID- 29590381 TI - The Circadian Rhythm-Related MTNR1B Genotype, Gestational Weight Gain, and Postpartum Glycemic Changes. AB - Context: Disturbed circadian rhythms and sleep quality during pregnancy have been related to gestational weight gain and gestational diabetes mellitus (GDM), which affect postpartum glucose metabolism and future risk of type 2 diabetes. Objective: We assessed whether the circadian rhythm-related melatonin receptor 1B (MTNR1B) genotype was associated with 1 to 5 years of postpartum glycemic changes among women with a history of GDM and whether gestational weight gain modified such associations. Design, Settings, and Participants: The established circadian rhythm-associated MTNR1B genetic variant (rs10830963) was genotyped in 1025 Chinese women with a history of GDM. Body weight and glycemic traits, during and after pregnancy, were longitudinally collected. Main Outcome Measures: The main outcome measure was postpartum glycemic changes. Results: We found that women carrying different MTNR1B genotypes showed distinct postpartum changes in 2-hour oral glucose tolerance test: 0.36, 0.20, and -0.19 mM per additional copy of the shorter sleep duration-related G allele in women with inadequate, adequate, and excessive gestational weight gain, respectively (for interaction, P = 0.028). The corresponding changes in fasting glucose were 0.14, 0.13, and 0.01 mM, although the modification effect of gestational weight gain on the genetic association was marginally significant (for interaction, P = 0.067). Conclusions: Our findings suggest that gestational weight gain may modify the circadian rhythm-related MTNR1B genetic variant on long-term glycemic changes, highlighting the significance of gestational weight management in diabetes prevention among women with GDM. PMID- 29590383 TI - The Cox-maze IV procedure in its second decade: still the gold standard? AB - Atrial fibrillation (AF) is the most common cardiac arrhythmia and the treatment options include medical treatment and catheter-based or surgical interventions. AF is a major cause of stroke, and its prevalence is increasing. The surgical treatment of AF has been revolutionized over the past 2 decades through surgical innovation and improvements in endoscopic imaging, ablation technology and surgical instrumentation. The Cox-maze (CM) procedure, which was developed by James Cox and introduced clinically in 1987, is a procedure in which multiple incisions are created in both the left and the right atria to eliminate AF while allowing the sinus impulse to reach the atrioventricular node. This procedure became the gold standard for the surgical treatment of AF. Its latest iteration is termed the CM IV and was introduced in 2002. The CM IV replaced the previous cut-and-sew method (CM III) by replacing most of the incisions with a combination of bipolar radiofrequency and cryoablation. The use of ablation technologies, made the CM IV technically easier, faster and more amenable to minimally invasive approaches. The aims of this article are to review the indications and preoperative planning for the CM IV, to describe the operative technique and to review the literature including comparisons of the CM IV with the previous cut and-sew method. Finally, this review explores future directions for the surgical treatment of patients with AF. PMID- 29590384 TI - Atrial remodelling and function: implications for atrial fibrillation surgery. AB - The exact mechanism of atrial fibrillation (AF) is still incompletely understood. A number of alterations that impact focal electrical discharge, the atrial substrate and modulating factors contribute to its pathogenesis. Atrial remodelling (resulting in atrial cardiomyopathy) sets the stage for AF development. Once present, AF results in the loss of synchronized atrial contraction, which affects ventricular filling and atrial reservoir and conduit functions. Passive atrial function is particularly important in patients with left ventricular diastolic dysfunction. AF can cause tachycardiomyopathy, a mostly reversible cardiac alteration induced by tachycardia. At a structural level, atrial support is also instrumental to the function of atrioventricular valves. All of these functions can be recovered to variable degrees via rhythm control strategies. Surgical and hybrid ablation show very promising results, especially in patients with a more advanced disease substrate. This review highlights the pathophysiological aspects of AF related to left atrial function and their practical implications for surgical rhythm management. PMID- 29590385 TI - The New 2016 European Society of Cardiology/European Association for Cardio Thoracic Surgery Guidelines: Enough Guidance? Enough Evidence? AB - For the first time, the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have joined forces to develop consensus guidelines for the management of atrial fibrillation (AF). One of the main issues is the integrated care of patients with AF, with emphasis on multidisciplinary teams of general physicians, cardiologists, stroke specialists and surgeons, together with the patient's involvement for better management of AF. These guidelines also help in the detection of risk factors and concomitant cardiovascular diseases, stroke prevention therapies, including anticoagulation and antiplatelet therapies after acute coronary episodes, major haemorrhages or strokes. In the field of ablation, surgery plays an important role as concomitant with other surgical procedures, and it should be considered in symptomatic patients with the highest level of evidence. Asymptomatic patients with mitral insufficiency should also be considered for combined mitral and AF surgery if they have new-onset AF. In patients with stand-alone AF, recommendations for minimally invasive ablation have an increased level of recommendation and should be considered as the same level as catheter ablation in patients with persistent or long-standing persistent AF or with paroxysmal AF who fail catheter ablation. Surgical occlusion or exclusion of the left atrial appendage may be considered for stroke prevention in patients with AF about to have surgery. Nevertheless, not enough is known to avoid long-term anticoagulation in patients at risk of stroke even if the left atrial appendage has been excluded. These Guidelines provide a full spectrum of recommendations on the management of patients with AF including prevention, treatment and complications based on the latest published evidence. PMID- 29590386 TI - Surgical management of the left atrial appendage: a must or a myth? AB - Surgical treatment of the left atrial appendage (LAA) has increased over the past few years. The most serious complication of atrial fibrillation is a cerebral cardioembolic stroke. In most patients with atrial fibrillation, the LAA is the anatomical source of the embolism. Several surgical techniques for occluding the LAA using different devices have been developed with different prospects of success. It is still not clear which of these techniques represents the optimum treatment for reducing the incidence of stroke in patients with atrial fibrillation. This text focuses on the surgical closure of LAA and critically considers the results with respect to closure success and the associated complications. PMID- 29590387 TI - Three-year follow-up of hybrid ablation for atrial fibrillation. AB - OBJECTIVES: The single-step hybrid atrial fibrillation (AF) ablation procedure combines a transvenous endocardial and thoracoscopic epicardial approach in 1 procedure. Short-term results are encouraging, but long-term outcome data are not available. METHODS: Hybrid AF ablation was successfully performed in 64 consecutive patients (53% with persistent AF). The mean follow-up period was 1732 +/- 353 days. Perprocedural endocardial touch-up of incomplete epicardial lesions was performed in 17 (26%) patients. RESULTS: In paroxysmal AF patients, arrhythmia-free cumulative survival rates after 1 hybrid AF ablation without Class I or III antiarrhythmic drugs procedure and without redo catheter ablation were 83%, 80% and 80% after 1, 2 and 3 years, respectively. In (long-standing) persistent AF patients, these were 82%, 79% and 79% after 1, 2 and 3 years. Thirteen (20%) patients had at least 1 recurrent episode of supraventricular arrhythmia lasting longer than 30 s: the most frequent recurrent arrhythmias were left atrial flutter and AF. No mortality or conversion to cardiopulmonary bypass, no phrenic nerve palsy and no pacemaker implantation were reported. CONCLUSIONS: Hybrid AF ablation, combining a transvenous endocardial and thoracoscopic epicardial approach in a single procedure, results in a cumulative 3-year freedom from arrhythmia without Class I or III antiarrhythmic drugs and without redo catheter ablation of 80% in paroxysmal AF (24 of 30 patients) and 79% in non paroxysmal AF (26 of 33 patients).

AB - Background: Long non-coding RNAs (lncRNAs) have essential regulatory function, yet their roles in colorectal cancer (CRC) are not well understood. Materials and methods: Microarray was applied to detect lncRNAs expression profiles in tumor tissues, liver metastasis and paired adjacent normal tissues of CRC. And using RT PCR to verify chip results. Results: A total of 10 680 lncRNAs demonstrated differential expressions (fold change >=2) between tumor tissues and adjacent normal tissues; furthermore there were 2970 lncRNAs, which showed different expression level between CRC tissues with liver metastasis and adjacent normal tissues. Especially, lncRNA-AK098783 expression level was frequently higher in cancerous tissues than corresponding noncancerous tissue. Higher AK098783 expression was significantly correlated with shortened overall survival (P < 0.001) and distant metastasis (P < 0.001). Conclusions: Our results suggest that AK098783 is involved in distant metastasis and dramatically associated with poor prognosis in patients with CRC. PMID- 29590394 TI - Evolutionary Origins of Toll-like Receptor Signaling. AB - Toll-like receptors (TLRs) are transmembrane pattern recognition receptors that are best known for their roles in innate immunity for the detection of and defense against microbial pathogens. However, TLRs also have roles in many nonimmune processes, most notably development. TLRs direct both immune and developmental programs by activation of downstream signaling pathways, often by activation of the NF-kappaB pathway. There are two primary TLR subtypes: 1) TLRs with multiple cysteine clusters in their ectodomain (mccTLRs) and 2) TLRs with a single cysteine cluster in their ectodomain (sccTLRs). For some time, it has been known that TLRs and the biological processes that they control are conserved in organisms from insects to mammals. However, genome and transcriptome sequencing has revealed that many basal metazoans also have TLRs and downstream NF-kappaB signaling components. In this review, we discuss what is known about the structure, biological function, and downstream signaling pathways of TLRs found in phyla from Porifera through Annelida. From these analyses, we hypothesize that mccTLRs emerged in the phylum Cnidaria, that sccTLRs evolved in the phylum Mollusca, and that TLRs have dual immune and developmental biological functions in organisms as ancient as cnidarians. PMID- 29590395 TI - Anaerobic phototrophic processes of hydrogen production by different strains of microalgae Chlamydomonas sp. AB - Hydrogen is an abundant element and a non-polluting fuel that can be biologically produced by microalgae. The aim of this research was to investigate biological hydrogen production by Chlamydomonas reinhardtii (CC425) and Chlamydomonas moewusii (SAG 24.91) by direct biophotolysis in batch cultures. Strains were cultivated in TAP growth medium (pH 7.2) in two phases: in the first stage, cultures were maintained in an aerobic condition until the middle of the exponential phase; in the second stage, the biomass was transferred to closed anaerobic photobioreactors under sulfur deprived. Gas chromatography and Gompertz model were used to measure the hydrogen production and hydrogen production rate, respectively. We noticed that maximum hydrogen production by biomass of C. reinhardtii was 5.95 +/- 0.88 MUmol mg-1 and the productivity was 17.02 +/- 3.83 MUmol L-1 h-1, with hydrogen production five times higher than C. moewusii, approximately, though, C. moewusii obtained a higher ethanol yield compared to C. reinhardtii. The hydrogen production method, with the cultivation of strains in two different phases and sulfur deprivation, was effective for obtaining of biohydrogen for Chlamydomonas; however, it depends on the species, strain and growth conditions.

AB - Two species of the ixodid tick genus Dermacentor Koch, 1844 (Acari: Ixodidae) have previously been documented from Laos: D. auratus Supino, 1897 and D. steini (Schulze, 1933). Between 2012 and 2017, we recorded four additional Dermacentor species from this country: D. bellulus (Schulze, 1935); D. compactus Neumann, 1901; D. filippovae Apanaskevich & Apanaskevich, 2015; and D. tamokensisApanaskevich & Apanaskevich, 2016.

PMID- 29590397 TI - An Ecoinformatics Approach to Field-Scale Evaluation of Insecticide Effects in California Citrus: Are Citrus Thrips and Citrus Red Mite Induced Pests? AB - Experimental approaches to studying the consequences of pesticide use, including impacts on beneficial insects, are vital; however, they can be limited in scale and realism. We show that an ecoinformatics approach that leverages existing data on pesticides, pests, and beneficials across multiple fields can provide complementary insights. We do this using a multi-year dataset (2002-2013) on pesticide applications and density estimates of two pests, citrus thrips (Scirtothrips citri (Moulton [Thysanoptera: Thripidae])) and citrus red mites (Panonychus citri McGregor [Acari: Tetranychidae]), and a natural enemy (Euseius spp. predatory mites) collected from citrus groves in the San Joaquin Valley of California. Using correlative analyses, we investigated the long-term consequences of pesticide use on S. citri and P. citri population densities to evaluate the hypothesis that the pest status of these species is largely due to the disruption of natural biological control-i.e., these are induced pests. We also evaluated short-term pesticide efficacy (suppression of citrus thrips and citrus red mite populations immediately post-application) and asked if it was correlated with the suppression of Euseius predator populations. Although the short-term efficacy of different pesticides varied significantly, our dataset does not suggest that the use of citrus pesticides suppressed Euseius densities or worsened pest problems. We also find that there is no general trade-off between pesticide efficacy and pesticide risk to Eusieus, such that highly effective and minimally disruptive compounds were available to citrus growers during the studied time period. PMID- 29590398 TI - General practitioners' use of sickness certification guidelines in Sweden at introduction and four years later: a survey study. AB - Objective: National sickness certification guidelines were introduced in Sweden in 2007, comprising both overarching and diagnoses-specific recommendations. This study aimed to investigate how general practitioners (GP) used and perceived the usefulness of these guidelines in the sickness certification process close after introduction and 4 years later. Design: Two nationwide cross-sectional surveys in 2008 and 2012. Setting: Swedish healthcare. Participants: Physicians working in primary healthcare and having sickness certification consultations at least a few times per year (n = 4214 in 2008, and n = 4067 in 2012). Main Outcome Measures: Frequency of use and perceived usefulness of the sickness certification guidelines. Results: Most GPs used the guidelines at least a few times per year (in 2008 74.6%; in 2012 85.2%). In 2008, 44.1% reported a need to develop competence in using the guidelines, compared with 23.3% in 2012. Of those using the guidelines, 36.7% in 2008 and 44.6% in 2012 reported it problematic to write sickness certificates in accordance with the guidelines. Most GPs (89.2% in 2008 and 88.8% in 2012) valued the guidelines beneficial to ensure quality in sickness certification consultations. A larger proportion in 2012 compared with 2008 reported that the guidelines facilitated contacts with patients (61.2%, respectively, 55.6%), as well as with other stakeholders. Conclusions: The guidelines were perceived as useful and beneficial to ensure high quality in sickness certification consultations, and facilitated contacts with patients as well as other stakeholders. In 2012, still one-fourth reported a need to develop more competence in using the sickness certification guidelines. PMID- 29590399 TI - Patterns of cancer treatment in different age groups in Japan: an analysis of hospital-based cancer registry data, 2012-2015. AB - Background: Because of the physiological decline and the diversity of preferences, treating older patients with cancer is challenging. Given the insufficient evidence applicable to treating cancer in older patients, some clinical guidance is necessary. This study provides a description of current treatment practices in Japan, which may shed light on possible treatment options. Methods: Using data from the national database of hospital-based cancer registries, we described the first-course treatment of nine common cancers in patients who received care in Designated Cancer Care Hospitals between 2012 and 2015. We compared the patterns of first-course cancer treatment between younger and older patients. Results: In total, 1 383 066 cases were analysed. The proportion of patients aged >75 years receiving first-course treatment has gradually increased since 2012 (range: 0.9% point increase for colorectal cancer to 2.7% point increase for stomach cancer). A higher proportion of patients aged >=85 years, compared with younger patients, did not receive any treatment. Conclusions: Based on this cancer registry-based analysis, older patients-in particular those >=85 years old at diagnosis and with advanced stage cancer-are less likely to receive anti-cancer treatment than younger patents are. Further research is warranted to identify patient characteristics that predict which older patients are most likely to benefit from active treatment. PMID- 29590400 TI - Perceptions and attitudes regarding antibiotic resistance in Germany: a cross sectoral survey amongst physicians, veterinarians, farmers and the general public. AB - Background: Drivers of antibiotic (AB) resistance (ABR) include outpatient treatment, hospital care and animal husbandry. During the first phase of the One Health project RAI (Responsible Antibiotic Use via Information and Communication) surveys were conducted in these sectors. Objectives: To compare perceptions and attitudes towards ABR among general practitioners (GPs), hospital physicians, veterinarians, pig farmers and the general public. Methods: Cross-sectional questions on AB use and ABR were integrated in group-specific surveys of GPs, hospital physicians, veterinarians, pig farmers and the German general population. Results: A total of 1789 participants (340 GPs, 170 hospital physicians, 215 pig farmers, 60 veterinarians and 1004 members of the public) responded. Each group tended to identify drivers of ABR as being from outside its own area of activity. Guidelines were shown to be an important information source for AB therapy for all prescriber groups, but the frequency of routine use differed (39% of GPs, 65% of hospital physicians and 53% of veterinarians). Regarding further information sources, hospital physicians preferred smartphone apps and e-learning, GPs preferred non-sponsored training and veterinarians preferred multidisciplinary networks and e-learning. Farmers were predominantly satisfied with existing solutions. Farmers had three times better basic knowledge of ABR and knew twice as many people with MDR organism problems than the general public. They also received information on ABR more often from their veterinarians than patients did from their doctors. Conclusions: This study reveals considerable differences in perceptions and attitudes to ABR among the groups investigated. The results can help to tailor future interventions. Furthermore, they promote mutual understanding and thus support the One Health approach. PMID- 29590401 TI - Noradrenergic Activity in the Human Brain: A Mechanism Supporting the Defense Against Hypoglycemia. AB - Context: Hypoglycemia, one of the major factors limiting optimal glycemic control in insulin-treated patients with diabetes, elicits a brain response to restore normoglycemia by activating counterregulation. Animal data indicate that local release of norepinephrine (NE) in the hypothalamus is important for triggering hypoglycemia-induced counterregulatory (CR) hormonal responses. Objective: To examine the potential role of brain noradrenergic (NA) activation in humans during hypoglycemia. Design: A hyperinsulinemic-hypoglycemic clamp was performed in conjunction with positron emission tomographic imaging. Participants: Nine lean healthy volunteers were studied during the hyperinsulinemic-hypoglycemic clamp. Design: Participants received intravenous injections of (S,S)-[11C]O methylreboxetine ([11C]MRB), a highly selective NE transporter (NET) ligand, at baseline and during hypoglycemia. Results: Hypoglycemia increased plasma epinephrine, glucagon, cortisol, and growth hormone and decreased [11C]MRB binding potential (BPND) by 24% +/- 12% in the raphe nucleus (P < 0.01). In contrast, changes in [11C]MRB BPND in the hypothalamus positively correlated with increments in epinephrine and glucagon levels and negatively correlated with glucose infusion rate (all P < 0.05). Furthermore, in rat hypothalamus studies, hypoglycemia induced NET translocation from the cytosol to the plasma membrane. Conclusions: Insulin-induced hypoglycemia initiated a complex brain NA response in humans. Raphe nuclei, a region involved in regulating autonomic output, motor activity, and hunger, had increased NA activity, whereas the hypothalamus showed a NET-binding pattern that was associated with the individual's CR response magnitude. These findings suggest that NA output most likely is important for modulating brain responses to hypoglycemia in humans. PMID- 29590402 TI - Benign Thyroid Diseases and Risk of Thyroid Cancer: A Nationwide Cohort Study. AB - Context: Thyroid nodules, adenomas, and goiter have consistently been associated with thyroid cancer risk. Few studies have assessed whether thyroid dysfunction and thyroid autoimmunity influence this risk. Objective: To examine thyroid cancer risk after diagnoses of a wide range of benign thyroid conditions. Design: Hospital and cancer registry linkage cohort study for the years 1978 to 2013. Setting: Nationwide (Denmark). Participants: Patients diagnosed with hyperthyroidism (n = 85,169), hypothyroidism (n = 63,143), thyroiditis (n = 12,532), nontoxic nodular goiter (n = 65,782), simple goiter (n = 11,582), other/unspecified goiter (n = 21,953), or adenoma (n = 6,481) among 8,258,807 residents of Denmark during the study period. Main Outcome Measures: We computed standardized incidence ratios (SIRs) for differentiated thyroid cancer, excluding the first 12 months of follow-up after benign thyroid disease diagnosis. Results: SIRs were significantly elevated for all benign thyroid diseases apart from hypothyroidism. SIRs were higher for men than women and in the earlier follow-up periods. Elevated SIRs were observed for localized and regional/distant thyroid cancer. After excluding the first 10 years of follow-up, hyperthyroidism [n = 27 thyroid cancer cases; SIR = 2.00; 95% confidence interval (CI): 1.32 to 2.92], nontoxic nodular goiter (n = 83; SIR = 4.91; 95% CI: 3.91 to 6.09), simple goiter (n = 8; SIR = 4.33; 95% CI: 1.87 to 8.53), other/unspecified goiter (n = 20; SIR = 3.94; 95% CI: 2.40 to 6.08), and adenoma (n = 9; SIR = 6.02; 95% CI: 2.76 to 11.5) remained positively associated with thyroid cancer risk. Conclusions: We found an unexpected increased risk of differentiated thyroid cancer, including regional/distant disease, following diagnosis of hyperthyroidism and thyroiditis that could not be solely attributed to increased medical surveillance. Hypothyroidism was less clearly associated with thyroid cancer risk. PMID- 29590403 TI - p.Val804Met, the Most Frequent Pathogenic Mutation in RET, Confers a Very Low Lifetime Risk of Medullary Thyroid Cancer. AB - Context: To date, penetrance figures for medullary thyroid cancer (MTC) for variants in rearranged during transfection (RET) have been estimated from families ascertained because of the presence of MTC. Objective: To gain estimates of penetrance, unbiased by ascertainment, we analyzed 61 RET mutations assigned as disease causing by the American Thyroid Association (ATA) in population whole exome sequencing data. Design: For the 61 RET mutations, we used analyses of the observed allele frequencies in ~51,000 individuals from the Exome Aggregation Consortium (ExAC) database that were not contributed via The Cancer Genome Atlas (TCGA; non-TCGA ExAC), assuming lifetime penetrance for MTC of 90%, 50%, and unbounded. Setting: Population-based. Results: Ten of 61 ATA disease-causing RET mutations were present in the non-TCGA ExAC population with observed frequency consistent with penetrance for MTC of >90%. For p.Val804Met, the lifetime penetrance for MTC, estimated from the allele frequency observed, was 4% [95% confidence interval (CI), 0.9% to 8%]. Conclusions: Based on penetrance analysis in carrier relatives of p.Val804Met-positive cases of MTC, p.Val804Met is currently understood to have high-lifetime penetrance for MTC (87% by age 70), albeit of later onset of MTC than other RET mutations. Given our unbiased estimate of penetrance for RET p.Val804Met of 4% (95% CI, 0.9% to 8%), the current recommendation by the ATA of prophylactic thyroidectomy as standard for all RET mutation carriers is likely inappropriate. PMID- 29590404 TI - Intraoperative customized double-patch device with twin sutures for multiple muscular septal defects. AB - OBJECTIVES: Closure of multiple muscular ventricular septal defects (VSDs) remains a challenge because of anatomical complexity. METHODS: We mapped all the VSDs using en face reconstruction of the right ventricular septal surface through echocardiography and then performed an 'Intraoperative Customized Double-Patch Device' technique to surgically close them in 39 patients (male:female = 25:14). The median age of the patients was 6 months (2 months-10 years), and mean weight was 5.98 +/- 4.21 kg. A patch of polytetrafluoroethylene was placed on the left ventricular side of the defect and another on the right ventricular side, and they were anchored to each other using 2 polypropylene sutures. Residual shunts were evaluated using intraoperative echocardiography and measurements of right atrial-pulmonary arterial saturation were taken in all patients. RESULTS: The distribution of muscular VSDs was as follows: anterior muscular 12, posterior muscular 18, mid-muscular 11 and apical 9. The associated lesions included perimembranous VSD (n = 28), tetralogy of Fallot (n = 6), double-outlet right ventricle (n = 2) and supramitral membrane (n = 2). Mean clamp time and bypass time were 93 +/- 19 min and 147 +/- 26 min, respectively. Mean hospital stay was 11 +/- 3.39 days with no in-hospital mortality. Five patients with significant residual shunts needed concomitant PA banding. All patients remained in New York Heart Association Class I. There was either no residual shunt (n = 3) or trivial shunt (n = 2) among the banded patients. All patients remained symptom-free and continued to thrive well at the most recent follow-up (3.48 +/- 1.51 years). CONCLUSIONS: Muscular VSDs can be mapped through en face reconstruction and closed using intraoperative customized double-patch device technique in a variety of situations with satisfactory immediate and short-term results. PMID- 29590405 TI - Selection of host-plant genotype: the next step to increase grain legume N2 fixation activity. AB - Symbiotic N2 fixation research thus far has been primarily focused on selection of bacteria. However, little progress in impacting crop yields has resulted from this approach. Bacteria introduced in field soils rarely compete well with indigenous bacteria, including mutated lines selected for high nitrogen fixation capacity. Consequently, introduction of 'elite' bacteria in fields commonly does not result in crop yield increase. This review highlights that the primary regulation of N2 fixation is a result of response of integrated physiological activity at the plant level. Nitrogen feedback from the host plant plays an important role in regulating the N2 fixation rate. Rapid sequestration of fixed nitrogen by the plant is especially important for high N2 fixation activity. In addition, water cycling in the plant between the shoot and nodules plays a key role in sustaining high N2 fixation activity. Therefore, attention in selecting the host-plant genotype is suggested to be the next step to increasing N2 fixation activity of grain legumes. PMID- 29590406 TI - Medical Evaluation Board Involvement, Non-Credible Cognitive Testing, and Emotional Response Bias in Concussed Service Members. AB - Introduction: Military Service Members (SMs) with post-concussive symptoms are commonly referred for further evaluation and possible treatment to Department of Defense Traumatic Brain Injury Clinics where neuropsychological screening/evaluations are being conducted. Understudied to date, the base rates of noncredible task engagement/performance validity testing (PVT) during cognitive screening/evaluations in military settings appears to be high. The current study objectives are to: (1) examine the base rates of noncredible PVTs of SMs undergoing routine clinical or Medical Evaluation Board (MEB) related workups using multiple objective performance-based indicators; (2) determine whether involvement in MEB is associated with PVT or symptom exaggeration/symptom validity testing (SVT) results; (3) elucidate which psychiatric symptoms are associated with noncredible PVT performances; and (4) determine whether MEB participation moderates the relationship between psychological symptom exaggeration and whether or not SM goes on to demonstrate PVTs failures - or vice versa. Materials and Methods: Retrospective study of 71 consecutive military concussion cases drawn from a DoD TBI Clinic neuropsychology clinic database. As part of neuropsychological evaluations, patients completed several objective performance-based PVTs and SVT. Results: Mean (SD) age of SMs was 36.0 (9.5), ranging from 19-59, and 93% of the sample was male. The self-identified ethnicity resulted in the following percentages: 62% Non-Hispanic White, 22.5% African American, and 15.5% Hispanic or Latino. The majority of the sample (97%) was Active Duty Army and 51% were involved in the MEB at the time of evaluation. About one-third (35.9%) of routine clinical patients demonstrated failure on one or more PVT indicators (12.8% failed 2) while PVT failure rates amongst MEB patients ranged from 15.6% to 37.5% (i.e., failed 2 or 1 PVTs, respectively). Base rates of failures on one or more PVT did not differ between routine clinical versus MEB patients (p = 0.94). MEB involvement was not associated with increased emotional symptom response bias as compared to routine clinical patients. PVT failures were positively correlated with somatization, anxiety, depressive symptoms, suspicious and hostility, atypical perceptions/alienation/subjective cognitive difficulties, borderline personality traits/features, and penchant for aggression in addition to symptom over-endorsement/exaggeration. No differences between routine clinical and MEB patients across other SVT indicators were found. MEB status did not moderate the relationship between any of the SVTs. Conclusion: Study results are broadly consistent with the prior published studies that documented low to moderately high base rates of noncredible task engagement during neuropsychological evaluations in military and veteran settings. Results are in contrast to prior studies that have suggested involvement in MEB is associated with increased likelihood of poor PVT performances. This is the first to show that MEB involvement did not enhance/strengthen the association between PVT performances and evidence of SVTs. Consistent with prior studies, these results do highlight that the same SMs who fail PVTs also tend to be the ones who go on to endorse a myriad of psychiatric symptoms and proclivities. Implications of variable or poor task engagement during routine clinical and MEB neuropsychological evaluation in military settings on treatment and disposition planning cannot be overstated. PMID- 29590407 TI - Costs associated with febrile neutropenia in Japanese patients with primary breast cancer: post-hoc analysis of a randomized clinical trial. AB - Background: Febrile neutropenia (FN), a decrease in blood neutrophils accompanied by fever, is a major adverse event (AE) associated with cancer chemotherapy. We aimed to estimate the direct medical costs associated with FN management in breast cancer patients within a clinical trial with pegfilgrastim, a pegylated form of recombinant granulocyte colony-stimulating factor (G-CSF). Methods: We obtained data from 346 Japanese breast cancer patients in a randomized, placebo controlled clinical trial comparing FN incidence due to TC adjuvant chemotherapy (docetaxel 75 mg/m2, cyclophosphamide 600 mg/m2) between pegfilgrastim-treated and placebo groups. We estimated mean costs for chemotherapy drugs, drugs for all AEs and FN, and hospitalization for all AEs and FN. We also calculated mean costs associated with drugs and hospitalization for FN specifically for patients who developed FN in the placebo group. Results: For the pegfilgrastim and placebo groups, the total cost during the first cycle of chemotherapy was Y189 135 and Y98 106. This difference is associated with prophylactic use of pegfilgrastim. Our analysis clarified in the placebo group that FN incidents of 119/173 (68.6%), the mean drug cost related to all AEs and hospitalization caused by the first cycle of chemotherapy were Y14 411and Y11 180, respectively. The cost of each for FN treatment was Y16 429 for the placebo group. The mean treatment cost for patients who developed FN in placebo group, was Y11 145 for drugs and Y28 420 for drugs and hospitalization. Conclusions: Pegfilgrastim reduced the costs incurred for both drugs and hospitalization for AEs as well as FN, although the total medical cost during the chemotherapy increased. Our study constitutes baseline data for further health economic evaluations of pegfilgrastim. PMID- 29590408 TI - Phase retrieval using through-focus images in Lorentz transmission electron microscopy. AB - In this study, we report on phase retrieval by the maximum likelihood method with conjugate gradient method (CG-MAL) using through-focus images in Lorentz transmission electron microscopy (LTEM). The method was evaluated using 32 simulated and experimentally obtained through-focus images of magnetic bubbles; these images were collected under a defocus range from approximately -3 mm to 3 mm. Consequently, we obtained the magnetic domain structures of the magnetic bubbles in both the simulation and the LTEM experiment. Furthermore, the CG-MAL method showed better convergence behavior than other iterative phase retrieval methods. Therefore, the method can also be widely and effectively applied to the observation of magnetic domain structures other than magnetic bubbles when highly defocused through-focus images are used. PMID- 29590409 TI - Motor Unit Number Estimate and Isometric Hand Grip Strength in Military Veterans with or Without Muscular Complaints: Reference Values for Longitudinal Follow-up. AB - Introduction: It remains unclear if Gulf War (GW) veterans have a higher risk of developing motor neuron disorder. We intended to establish baseline neurophysiological values, including thenar motor unit number estimate (MUNE) and isometric hand grip (IHG) strength, to compare future follow-ups of deployed GW veterans with or without muscular complaints. Materials and Methods: We evaluated 19 GW veterans with self-reported weakness, cramps, or excessive muscle fatigue (Ill-19) and compared them with 18 controls without such muscular complaints (C 18). We performed MUNE on hand thenar muscles using adapted multipoint stimulation method for Ill-19 and 15 controls (C-15). We measured IHG strength (maximum force, endurance, and fatigue level) on Ill-19 and C-18 with a hand dynamometer. We performed nerve conduction studies on all study participants to determine which subjects had mild carpal tunnel syndrome (CTS). We compared the MUNE and IHG strength measures between Ill group and controls and between those with CTS and those without CTS. Results: We obtained thenar MUNE of Ill-19 (95% CI of mean: 143-215; mean age: 46 yr) and compared it with that of C-15 (95% CI of mean: 161-230; mean age: 45 yr), and 95% of CI of mean among IHG strength variables (maximum force: 324-381 Newton; endurance: 32-42 s; fatigue level: 24% 33%) compared with C-18 (maximum force: 349-408 Newton; endurance: 35-46 s; fatigue level: 21%-27%). There was no significant difference in either MUNE or IHG strength between Ill-19 group and controls. The MUNE and IHG maximum forces were significantly lower in those with CTS compared with those without CTS. As a surrogate of mild CTS, the median versus ulnar distal sensory latency on nerve conduction study was only weakly associated with MUNE, maximum force, and fatigue level, respectively. Conclusion: To our knowledge, no published study on MUNE reference values of military veteran population has been available. The quantifiable values of both thenar MUNE and IHG strength of military veterans serve as baselines for our longitudinal follow-up of motor neuron function of deployed troops. These reference values are also useful for other laboratories to study veterans' motor system with or without mild CTS. PMID- 29590410 TI - Stated Pain Levels, Opioid Prescription Volume, and Chronic Opioid Use Among United States Army Soldiers. AB - Introduction: The use of opioids has increased drastically over the past few years and decades. As a result, concerns have mounted over serious outcomes associated with chronic opioid use (COU), including dependency and death. A greater understanding of the factors that are associated with COU will be critical if prescribers are to navigate potentially competing objectives to provide compassionate care, while reducing the overall opioid use problem. In this study, we study pain levels and opioid prescription volumes and their effects on the risk of COU. This study leveraged passive data sources that support automated decision support systems (DSSs) currently employed in a large military population. The models presented compute monthly, person-specific, adjusted probability of subsequent COT and could potentially provide critical decision support for clinicians engaged in pain management. Materials and Methods: The study population included all outpatient presentations at military medical facilities worldwide among active duty United States Army soldiers during July 2011 to September 2014 (17,664,006 encounters; population N = 552,193). We conducted a retrospective cohort study of this population and employed longitudinal data and a discrete time multivariable logistic regression model to compute COT probability scores. The contribution of pain scores and opioid prescription quantities to the probability of COT represented analytic foci. Results: There were 13,891 subjects (2.5%) who experienced incident COT during the observed time period. Statistically significant interactions between pain scores and prescription quantity were present, in addition to effects of multiple other control variables. Counts of monthly opioid prescriptions and maximum stated pain scores per month were each positively associated with COT. A wide range in individual COT risk scores was evident. The effect of prescription volume on the COT risk was larger than the effect of the pain score, and the combined effect of larger pain scores and increased prescription quantity was moderated by the interaction term. Conclusions: The results verified that passive data on the US Army can support a robust COT risk computation in this population. The individual, adjusted risk level requires statistical analyses to be fully understood. Because the same data sources drive current military DSSs, this work provides the potential basis for new, evidence-based decision support resources for military clinicians. The strong, independent impact of increasing opioid prescription counts on the COT risk reinforces the importance of exploring alternatives to opioids in pain management planning. It suggests that changing provider behavior through enhanced decision support could help reduce COT rates. PMID- 29590411 TI - Wartime Soft Tissue Coverage Techniques for the Deployed Surgeon. AB - Background: Since the start of the conflict in the Middle East in 2001, military orthopedic surgeons have faced complex orthopedic injuries including high-energy soft tissue wounds, traumatic amputations, and open fractures. Although orthopedic surgeons are well trained in the management of osseous injuries, the treatment of soft tissue injuries can be technically challenging and unfamiliar. Early washout, debridement of devitalized tissue, external fixation of bony injuries, and antibiotic therapy remain the foundation of early wound management. However, these unique extremity injuries have no standard plan of care, and definitive treatment options continue to evolve. The following report highlights the typical cases seen in the wartime setting and offers possible solutions for the associated soft tissue injuries. Methods: A single orthopedic surgeon at a Role 3 combat support hospital performed all cases in this series. This study is a report of the cases that the orthopedic surgeon encountered while deployed and the various techniques that can be used to manage the complex wounds seen in a deployed setting. Findings: Twelve patients were included in this report and the data are shown. Of the 12 patients, 6 were injured by an improvised explosive device (IED), 4 were injured by a high-velocity gunshot wound (HVGSW), 1 was injured by a gunshot wound (GSW), and 1 was injured in an auto versus pedestrian motor vehicle crash. The wound sizes ranged from 10 to 300 cm2. All patients required more than one irrigation and debridement before wound closure. There was a successful outcome in 11 of the 12 patients. The only patient without a known successful outcome was lost to follow up. Six patients were treated with split thickness skin graft (STSG) alone. Four patients were treated with STSG plus an additional means of coverage. One patient was treated with a random flap and one patient was treated with a full thickness skin graft. Integra was used in two of the patients. Each of the patients in whom integra was used had exposed bone and had a successful outcome with respect to tissue coverage. Discussion: This study details different soft tissue coverage techniques that must be learned and possibly employed by the deployed surgeon. Limitations of this study include its retrospective nature and the selected sampling of cases. At initial presentation, the management of war wounds secondary to high-velocity gunshot wounds and improvised explosive devices can be quite daunting. Adhering to firm surgical principles of thorough and meticulous debridement is the foundation of later soft tissue reconstructive options. Once the tissue is deemed clear of infection and contamination, there are myriad treatment options utilizing flaps, synthetic materials, and skin grafting. These are relatively straightforward techniques that the general orthopedic surgeon can utilize while deployed in a combat setting. In the end, it is critical for deployed surgeons to learn multiple techniques to provide definitive soft tissue coverage in a wartime theater. PMID- 29590412 TI - Screening Spirometry in Military Personnel Correlates Poorly with Exercise Tolerance and Asthma History. AB - BACKGROUND: Spirometry is an easy-to-perform test for evaluating pulmonary symptoms but has several limitations to include adequate test performance for valid results. Spirometry is not recommended to screen a general population for evidence of pulmonary disease unless symptoms are present or longitudinal screening is done for potential occupational exposures. METHODS: A single spirometry examination was performed on 900 active duty Army soldiers, ages 18-35 yr, without documented respiratory disease. Abnormal studies were identified (obstructive, restrictive, mixed, and flow volume loop abnormalities) and compared with reported respiratory symptoms, smoking history, prior diagnosis of asthma, and failure of the Army physical fitness test 2-mile run using generalized linear modeling techniques. RESULTS: The cohort population had spirometry values comparable with published NHANES III reference values. Ninety eight subjects (10.9%) were identified with abnormal spirometry included 33 obstructive, 44 restrictive, 3 mixed, and 18 isolated flow volume loop abnormalities. Historical features (smoking, exertional dyspnea, cough, asthma, or APFT failure) had no effect on the probability of an abnormal spirometry result (p = 0.56). Although APFT failure probability is strongly affected by exertional dyspnea (p = 0.00) and current smoking (p = 0.01), abnormal spirometry results did not have a statistically significant effect (p = 0.38). DISCUSSION: For potential screening of military personnel with spirometry to detect pulmonary disease, study findings identified a significant percentage with non-specific abnormalities requiring further evaluation. Spirometry may be indicated in those individuals with a history of asthma or active dyspnea symptoms. Spirometry as a screening tool is poorly (and often incorrectly) predictive for respiratory symptoms or decreased exercise tolerance in a military cohort. CONCLUSION: Spirometry should not be used to screen the military force for the presence of respiratory disorders. In those individuals with a history of asthma, in-depth testing should be performed to fully evaluate any non-specific findings identified during spirometry.

AB - Objective: To estimate and compare the optimal cut-off score of Alcohol Use Disorders Identification Test (AUDIT) and AUDIT-C in identifying at-risk alcohol consumption, heavy episodic alcohol use, ICD-10 alcohol abuse and alcohol dependence in adolescents attending ED in England. Design: Opportunistic cross sectional survey. Setting: 10 emergency departments across England. Participants: Adolescents (n = 5377) aged between their 10th and 18th birthday who attended emergency departments between December 2012 and May 2013. Measures: Scores on the AUDIT and AUDIT-C. At-risk alcohol consumption and monthly episodic alcohol consumption in the past 3 months were derived using the time-line follow back method. Alcohol abuse and alcohol dependence was assessed in accordance with ICD 10 criteria using the MINI-KID. Findings: AUDIT-C with a score of 3 was more effective for at-risk alcohol use (AUC 0.81; sensitivity 87%, specificity 97%), heavy episodic use (0.84; 76%, 98%) and alcohol abuse (0.98; 91%, 90%). AUDIT with a score of 7 was more effective in identifying alcohol dependence (0.92; 96%, 94%). Conclusions: The 3-item AUDIT-C is more effective than AUDIT in screening adolescents for at-risk alcohol use, heavy episodic alcohol use and alcohol abuse. AUDIT is more effective than AUDIT-C for the identification of alcohol dependence. PMID- 29590417 TI - Strategies for Establishing a Rearing Technique for the Fruit Fly Parasitoid: Doryctobracon brasiliensis (Hymenoptera: Braconidae). AB - Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is the most important pest in South American orchards. When control measures are not adopted, this pest can cause losses of up to 100%. Doryctobracon brasiliensis (Szepligeti) (Hymenoptera: Braconidae) is a larval-pupal endoparasitoid that can be used as a native biological control agent against A. fraterculus. This study aimed to develop a rearing technique for D. brasiliensis in larvae of A. fraterculus. Trials were carried out to: 1) determine the optimal instar for parasitism, 2) define the exposure time of larvae to parasitoids, 3) determine the density requirements of A. fraterculus larvae offered to each parasitoid, and 4) evaluate the effect of diet on adults of D. brasiliensis. In all trials, we evaluated the number of offspring, parasitism rate, and sex ratio. Moreover, in the experiment to investigate the effects of diet, we determined the longevity of males and females. In both choice and nonchoice parasitism tests, the parasitoids preferred third-instar larvae of A. fraterculus over second- and first-instar larvae. An exposure time of 12 h of A. fraterculus larvae produced larger numbers of parasitoids and higher parasitism rates. The density of 15 larvae of A. fraterculus to each female of D. brasiliensis produced a larger number of offspring. A supply of honey solution (20 and 50%) to the parasitoids yielded the highest number offspring and resulted in greater longevity. Our findings can be used to support the development of a mass rearing protocol for D. brasiliensis. PMID- 29590418 TI - Transcriptional and post-translational regulation of AccD6 in Mycobacterium smegmatis. AB - AccD6 is an important component of acetyl-CoA/propionyl-CoA carboxylase, which acts as a key role in mycolic acid synthesis and short chain fatty acyl-coenzyme A metabolism. In this study, we demonstrated that AccD6 of Mycobacterium smegmatis associates with AccA3 (alpha subunit of acetyl-CoA carboxylase, MSMEG_1807) and AccE (epsilon subunit, MSMEG_1812) to form the acetyl-CoA (propionyl-CoA) carboxylase. Results showed that the MSMEG_4331 subunit is a regulator that interacts with the promoter region of accD6 to inhibit its transcription. Transcription of accD6 was reduced by 50% in the mutant M. smegmatis strain overexpressing MSMEG_4331. Moreover, the activity of AccD6 was inhibited by acylation (such as acetylation and propionylation). These results demonstrate that AccD6 of M. smegmatis is regulated at both the transcriptional and post-translational levels. Our findings highlight the novel regulatory mechanism underlying mycolic acid biosynthesis in mycobacteria. PMID- 29590419 TI - Combat Injury of the Sciatic Nerve - An Institutional Experience. AB - Introduction: Combat injury of the sciatic nerve tends to be severe with variable but often profound consequences, is often associated with widespread soft tissue and bone injuries, significant neurologic impairment, severe neuropathic pain, and a prolonged recovery time. There is little contemporary data that describes the treatment and outcome of this significant military acquired peripheral nerve injury. We describe our institution's experience treating patients with combat acquired sciatic nerve injury in the recent Iraq and Afghanistan wars. Materials and Methods: IRB approval was obtained, and a retrospective review was performed of the records of 5,137 combat-related extremity injuries between June 2007 and June 2015 to identify patients with combat-acquired sciatic nerve injury without traumatic amputation of the injured leg. The most common mechanisms of injury were gunshot wound to the upper thigh or pelvis, followed by blast injury. Thirteen patients were identified that underwent sciatic nerve exploration and repair. Nine patients had nerve repair using long-length acellular cadaveric allografts. Five patients underwent nerve surgery within 30 d of injury and eight had surgery on a delayed basis. The postoperative follow-up period was at least 2 yr. Results: Reduction of neuropathic pain was significant, 7/10 points on the 11 point pain intensity numerical rating scale. Eight patients displayed electrodiagnostic evidence of reinnervation distal to the injury zone; however, functional recovery was poor, as only 3 of 10 patients had detectable motor units distal to the knee, and recovery was only in tibial nerve innervated muscles. There were no serious surgical complications, in particular, wound infection or graft rejection associated with long-length cadaver allograft placement. Conclusion: Early surgery to repair sciatic nerve injury possibly promotes significant pain reduction, reduces narcotic usage and facilitates a long rehabilitation process. Allograft nerve placement is not associated with serious complications. A follow-up period longer than 3 yr would be required and is ongoing to assess the efficacy of our treatment of patients with combat-acquired sciatic nerve injury. PMID- 29590420 TI - On-pump transapical cardioscopic mitral valve replacement with cardiac arrest: short-term results in a porcine survival model. AB - OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model. We hypothesized that MVR could be achieved with subannular implantation of the bioprosthesis via the TAC approach. METHODS: TAC MVR using the Hancock IITM (Medtronic)(r) mitral prosthesis was performed in 6 pigs via an incision over the xiphoid process, under cardiopulmonary bypass and cardiac arrest. COR-KNOT(r) and minimally invasive cardiac surgery instruments were used. Haemodynamics, echocardiography, cardiac computed tomography, ventriculography and electrocardiography were used to evaluate the function of the mitral prosthesis and left ventricle, coronary system and conduction system in the perioperative period and 4 weeks later. RESULTS: A postimplant examination showed that the mitral prosthesis was competent, without a paravalvular leak. The left ventricular ejection fraction was comparable to preoperative values (65.2 +/- 4.1 vs 67.2 +/- 7.9). The bypass, cross-clamp and implant times were 177.2 +/- 44.2 min, 135.3 +/- 47.6 min and 94.0 +/- 41.2 min, respectively. The prosthesis was in a good position. The apical scar was intact and not aneurysmal 4 weeks after the implant. The valve was properly sutured to the annulus, without a postimplant paravalvular leak. All animals recovered after 1 month of follow-up with preserved ventricular function and normal wall motion. CONCLUSIONS: We successfully managed to replace the mitral valve with a biological prosthesis via the apex with encouraging bypass and cross-clamp times. This technique may provide an alternative for a selected group of patients with diseased mitral valves who have indications for MVR and still in a high-risk redo setting with conventional sternotomy or minimally invasive cardiac surgery-MVR.

AB - Context: We compared the incidence of hypoglycemia after Roux-en-Y gastric bypass (RYGB) vs sleeve gastrectomy (SG). Design, Setting, and Main Outcome Measures: Randomized, open-label trial conducted at the outpatient obesity clinic in a university hospital in Rome, Italy. The primary aim was the incidence of reactive hypoglycemia (<3.1 mmol/L after 75-g oral glucose load) at 1 year after surgery. Secondary aims were hypoglycemia under everyday life conditions, insulin sensitivity, insulin secretion, and lipid profile. Results: Of 175 eligible patients, 120 were randomized 1:1 to RYGB or SG; 117 (93%) completed the 12-month follow-up. Reactive hypoglycemia was detected in 14% and 29% of SG and RYGB patients (P = 0.079), respectively, with the effect of treatment in multivariate analysis significant at P = 0.018. Daily hypoglycemic episodes during continuous glucose monitoring did not differ between groups (P = 0.75). Four of 59 RYGB subjects (6.8%) had 1 to 3 hospitalizations for symptomatic hypoglycemia vs 0 in SG. The static beta-cell glucose sensitivity index increased after both treatments (P < 0.001), but the dynamic beta-cell glucose sensitivity index increased significantly in SG (P = 0.008) and decreased in RYGB (P = 0.004 for time * treatment interaction). Whole-body insulin sensitivity increased about 10 fold in both groups. Conclusions: We show that reactive hypoglycemia is no less common after SG and is not a safer option than RYGB, but RYGB is associated with more severe hypoglycemic episodes. This is likely due to the lack of improvement of beta-cell sensitivity to changes in circulating glucose after RYGB, which determines an inappropriately high insulin secretion. PMID- 29590422 TI - Veteran Experiences Seeking Non-pharmacologic Approaches for Pain. AB - Introduction: Pain is a longstanding and growing concern among US military veterans. Although many individuals rely on medications, a growing body of literature supports the use of complementary non-pharmacologic approaches when treating pain. Our objective is to characterize veteran experiences with and barriers to accessing alternatives to medication (e.g., non-pharmacologic treatments or non-pharmacologic approaches) for pain in primary care. Materials and Methods: Data for this qualitative analysis were collected as part of the Effective Screening for Pain (ESP) study (2012-2017), a national randomized controlled trial of pain screening and assessment methods. This study was approved by the Veterans Affairs (VA) Central IRB and veteran participants signed written informed consent. We recruited a convenience sample of US military veterans in four primary care clinics and conducted semi-structured interviews (25-65 min) elucidating veteran experiences with assessment and management of pain in VA Healthcare Systems. We completed interviews with 36 veterans, including 7 females and 29 males, from three VA health care systems. They ranged in age from 28 to 94 yr and had pain intensity ratings ranging from 0 to 9 on the "pain now" numeric rating scale at the time of the interviews. We analyzed interview transcripts using constant comparison and produced mutually agreed upon themes. Results: Veteran experiences with and barriers to accessing complementary non-pharmacologic approaches for pain clustered into five main themes: communication with provider about complementary approaches ("one of the best things the VA has ever given me was pain education and it was through my occupational therapist"), care coordination ("I have friends that go to small clinic in [area A] and I still see them down in [facility in area B] and they're going through headaches upon headaches in trying to get their information to their primary care docs"), veteran expectations about pain experience ("I think as a society we have shifted the focus to if this doctor doesn't relieve me of my pain I will find someone who does"), veteran knowledge and beliefs about various complementary non-pharmacologic approaches ("how many people know that tai chi will help with pain?... Probably none. I saw them doing tai chi down here at the VA clinic and the only reason I knew about it was because I saw it being done"), and access ("the only physical therapy I ever did... it helped...but it was a two and-a-half-hour drive to get there three times a week... I can't do this"). Specific access barriers included local availability, time, distance, scheduling flexibility, enrollment, and reimbursement. Conclusion: The veterans in this qualitative study expressed interest in using non-pharmacologic approaches to manage pain, but voiced complex multi-level barriers. Limitations of our study include that interviews were conducted only in five clinics and with seven female veterans. These limitations are minimized in that the clinics covered are diverse ranging to include urban, suburban, and rural residents. Future implementation efforts can learn from the veterans' voice to appropriately target veteran concerns and achieve more patient-centered pain care. PMID- 29590423 TI - The first 5 years of Part 2A Orders: the use of powers from court applications to protect public health in England 2010-15. AB - Background: Part 2A Orders are the legal means which allow local authorities (LAs), upon application to court, to exercise powers over persons, things or premises to protect public health. Methods: We surveyed lead professionals involved in applications to understand the use and utility of such Orders since their inception in April 2010 to July 2015. Results: All applications for Orders were granted; 29 for persons (28 for tuberculosis, 1 for HIV); these were renewed in 18 (18/25, 72%) cases up to seven times; 23 applications related to things (tattoo and piercing equipment); and three applications related to 'premises' (Escherichia coli 0137 on farm, faecal contamination). Use of the Orders against things occurred where there was failure of the Health and Safety Executive to transfer powers to LAs. Orders against persons were used as a last resort and renewed until treatment completion in the minority of cases (n = 3). One patient was detained under quarantine powers while assessing infectiousness. Significant difficulties in implementing the Part 2A Orders due to lack of resources, facilities and interagency collaboration were reported. Conclusions: Part 2A Orders are used as a last resort but improved facilities for safe and secure isolation would help improve implementation. PMID- 29590424 TI - The T2-FLAIR mismatch sign as an imaging marker for non-enhancing IDH-mutant, 1p/19q-intact lower-grade glioma: a validation study. AB - Background: The purpose of this study was to assess the reproducibility of the previously described T2-fluid attenuated inversion recovery (FLAIR) mismatch sign as a specific imaging marker in non-enhancing isocitrate dehydrogenase (IDH) mutant, 1p/19q non-codeleted lower-grade glioma (LGG), encompassing both diffuse and anaplastic astrocytoma. Methods: MR scans (n = 154) from 3 separate databases with genotyped LGG were evaluated by 2 independent reviewers to assess (i) presence/absence of "T2-FLAIR mismatch" sign and (ii) presence/absence of homogeneous signal on T2-weighted images. Interrater agreement with Cohen's kappa (kappa) was calculated, as well as diagnostic test performance of the T2-FLAIR mismatch sign to identify IDH-mutant astrocytoma. Results: There was substantial interrater agreement for the T2-FLAIR mismatch sign [kappa = 0.75 (0.64-0.87)], but only fair agreement for T2 homogeneity [kappa = 0.38 (0.25-0.52)]. The T2 FLAIR mismatch sign was present in 38 cases (25%) and had a positive predictive value of 100%, negative predictive value of 68%, a sensitivity of 51%, and a specificity of 100%. Conclusions: With a robust interrater agreement, our study confirms that among non-enhancing LGG the T2-FLAIR mismatch sign represents a highly specific imaging marker for IDH-mutant astrocytoma. This non-invasive marker may enable a more informed patient counsel and can aid in the treatment decision processes in a significant proportion of patients presenting with non enhancing, LGG-like lesions. PMID- 29590425 TI - miR-106a Increases Granulosa Cell Viability and Is Downregulated in Women With Diminished Ovarian Reserve. AB - Context: Women with diminished ovarian reserve (DOR) have reduced fertility, cardiovascular events, and osteoporosis. Although differential microRNA (miRNA) expression has been described in several ovarian disorders, little is known about the role of miRNAs in the pathogenesis of DOR. Objective: Identify differentially expressed miRNAs in DOR and explore the role of miR-106a in human granulosa cell proliferation. Design: miRNA microarray (n = 3) and quantitative reverse transcription polymerase chain reaction (n = 30) were used to examine miRNA expression in serum and granulosa cells from normal-cycling and women with DOR. Primary human granulosa cells were treated alone or in combination with miR-106a mimic, miR-106a inhibitor, apoptosis signal-regulating kinase 1 (ASK1) small interfering RNA (siRNA), or p38 mitogen-activated protein kinase (MAPK) inhibitor (SB203580) before assessment of cell viability and apoptosis. Western blot was used to measure ASK1 protein and phosphorylation/activation of p38 MAPK. Binding of miR-106a to ASK1 mRNA was examined by 3' untranslated region (3'UTR) luciferase analysis. Results: Fifteen miRNAs were differentially expressed (n = 30), and miR-106a was downregulated in serum and granulosa cells of women with DOR. miR-106a mimic increased cell viability and attenuated apoptosis, whereas the converse occurred following treatment with miR-106a inhibitor. miR-106a suppressed ASK1 expression by directly targeting its 3'UTR. miR-106a inhibitor increased p38 MAPK phosphorylation/activation, and this effect was abolished by treatment with ASK1 siRNA. Whereas knockdown of ASK1 abolished the effects of miR 106a inhibitor on cell viability/apoptosis, pretreatment with SB203580 did not significantly alter the effects of miR-106a inhibitor. Conclusions: Downregulation of miR-106a may contribute to the pathogenesis of DOR by reducing granulosa cell viability and promoting apoptosis via enhanced ASK1 signaling.

PMID- 29590427 TI - The Commander's Wellness Program: Assessing the Association Between Health Measures and Physical Fitness Assessment Scores, Fitness Assessment Exemptions, and Duration of Limited Duty. AB - Introduction: Air Force Medical Service health promotions staff have identified a set of evidenced-based interventions targeting tobacco use, sleep habits, obesity/healthy weight, and physical activity that could be integrated, packaged, and deployed as a Commander's Wellness Program. The premise of the program is that improvements in the aforementioned aspects of the health of unit members will directly benefit commanders in terms of members' fitness assessment scores and the duration of periods of limited duty. The purpose of this study is to validate the Commander's Wellness Program assumption that body mass index (BMI), physical activity habits, tobacco use, sleep, and nutritional habits are associated with physical fitness assessment scores, fitness assessment exemptions, and aggregate days of limited duty in the population of active duty U.S. Air Force personnel. Methods: This study used a cross-sectional analysis of active duty U.S. Air Force personnel with an Air Force Web-based Health Assessment and fitness assessment data during fiscal year 2013. Predictor variables included age, BMI, gender, physical activity level (moderate physical activity, vigorous activity, and muscle activity), tobacco use, sleep, and dietary habits (consumption of a variety of foods, daily servings of fruits and vegetables, consumption of high-fiber foods, and consumption of high-fat foods). Nonparametric methods were used for the exploratory analysis and parametric methods were used for model building and statistical inference. Results: The study population comprised 221,239 participants. Increasing BMI and tobacco use were negatively associated with the outcome of composite fitness score. Increasing BMI and tobacco use and decreasing sleep were associated with an increased likelihood for the outcome of fitness assessment exemption status. Increasing BMI and tobacco use and decreasing composite fitness score and sleep were associated with an increased likelihood for the outcome of limited duty status, whereas increasing BMI and decreasing sleep were associated with the outcome of increased aggregate days of limited duty. The observed associations were in the expected direction and the effect sizes were modest. Physical activity habits and nutritional habits were not observed to be associated with any of the outcome measures. Conclusions: The Commander's Wellness Program should be scoped to those interventions targeting BMI, composite fitness score, sleep, and tobacco use. Although neither self-reported physical activity nor nutritional habits were associated with the outcomes, it is still worthwhile to include related interventions in the Commander's Wellness Program because of the finding in other studies of a consistent association between the overall number of health risks and productivity outcomes. PMID- 29590428 TI - Personality Factors and Their Impact on PTSD and Post-traumatic Growth is Mediated by Coping Style Among OIF/OEF Veterans. AB - Introduction: Traumatic experiences can trigger negative effects such as post traumatic stress disorder (PTSD). However, some individuals may also experience positive changes following trauma exposure. These changes are known as post traumatic growth (PTG). Dispositional and situational factors are likely at play in determining both severity of PTSD symptoms and whether and to what degree an individual experiences PTG. This study examined how coping style and personality traits interact to influence PTSD and PTG. Materials and Methods: Two hundred and seventy-one Operation Iraqi Freedom/Operation Enduring Freedom veterans not engaged in mental health treatment completed self-report measures of trauma exposure, personality traits, coping styles, PTSD symptoms, and PTG. The study was approved by the Minneapolis VAHCS Institutional Review Board. Results: Adaptive coping and positive personality traits such as openness were positively correlated with PTG. Maladaptive coping and neuroticism were positively correlated with PTSD symptoms. Regression analyses indicated that an inverted-U (quadratic) curve characterized the relationship between PTSD symptoms and PTG; veterans who reported moderate PTSD levels reported the most PTG. Mediation analyses revealed that adaptive coping partially mediated the relationship between openness and PTG. Maladaptive coping partially mediated the relationship between neuroticism and PTSD symptoms. Conclusion: This study demonstrated that coping style mediated relationships between personality traits and post-trauma outcomes. Our findings are subject to the limitations of the self-report and cross-sectional nature of the data. Longitudinal studies, preferably incorporating coping-oriented interventions, could convincingly demonstrate the impact of coping style on PTSD and PTG. As coping styles can be modified, our findings nonetheless suggest that coping-oriented clinical intervention has potential to reduce PTSD symptoms and promote positive growth following trauma exposure. PMID- 29590429 TI - Photosynthetic limitation as a factor influencing yield in highbush blueberries (Vaccinium corymbosum) grown in a northern European environment. AB - Published evidence indicates that nearly 60% of blueberry-producing countries experience yield instability. Yield is a complex trait determined by genetic and environmental factors. Here, using physiological and biochemical approaches, we tested the hypothesis that yield instability results from year-to-year environmental variation that limits carbon assimilation, storage and partitioning. The data indicate that fruit development depends primarily on the daily production of non-structural carbohydrates by leaves, and there is no accumulation of a starch buffer to allow continuous ripening under conditions limiting for photosynthesis. Photosynthesis was saturated at moderate light irradiance and this was mainly due to stomatal and biochemical limitations. In a dynamic light environment, photosynthesis was further limited by slow stomatal response to increasing light. Finally, labelling with 13CO2 at specific stages of fruit development revealed a relatively even distribution of newly assimilated carbon between stems, roots and fruits, suggesting that the fruit is not a strong sink. We conclude that a significant component of yield variability results from limitations in photosynthetic efficiency that are compounded by an inability to accumulate starch reserves in blueberry storage tissues in a typical northern European environment. This work informs techniques for improving agronomic management and indicates key traits required for yield stability in such environments. PMID- 29590431 TI - An overview of future EU health systems. An insight into governance, primary care, data collection and citizens' participation. AB - Background: Health systems in the European Union (EU) are being questioned over their effectiveness and sustainability. In pursuing both goals, they have to conciliate coexisting, not always aligned, realities. Methods: This paper originated from a workshop entitled 'Health systems for the future' held at the European Parliament. Experts and decision makers were asked to discuss measures that may increase the effectiveness and sustainability of health systems, namely: (i) increasing citizens' participation; (ii) the importance of primary care in providing integrated services; (iii) improving the governance and (iv) fostering better data collection and information channels to support the decision making process. Results: In the parliamentary debate, was discussed the concept that, in the near future, health systems' effectiveness and sustainability will very much depend on effective access to integrated services where primary care is pivotal, a clearer shift from care-oriented systems to health promotion and prevention, a profound commitment to good governance, particularly to stakeholders participation, and a systematic reuse of data meant to build health data-driven learning systems. Conclusions: Many health issues, such as future health systems in the EU, are potentially transformative and hence an intense political issue. It is policy-making leadership that will mostly determine how well EU health systems are prepared to face future challenges. PMID- 29590430 TI - The fungal phytotoxin lasiojasmonate A activates the plant jasmonic acid pathway. AB - Jasmonates are signaling compounds that regulate plant responses to stress. Jasmonic acid (JA) is the direct precursor of the bioactive plant hormone JA isoleucine (JA-Ile), the ligand of the CORONATINE INSENSITIVE 1-jasmonate ZIM domain (COI1-JAZ) co-receptor complex. JA, its methyl ester, and three furanonyl esters were recently isolated from the grapevine pathogen Lasiodiplodia mediterranea. The JA ester lasiojasmonate A (LasA) is the first reported naturally occurring JA-furanone, and its mode of action has not yet been elucidated. Here, we show that LasA activates many JA-regulated responses in planta, including protein degradation, gene expression, and physiological processes. These in vivo effects require LasA conversion into JA, formation of JA Ile, and its recognition by the plant JA-Ile perception complex. These findings suggest a mode of action of the natural fungal LasA as an inactive JA pool that can be transformed into the bioactive JA-Ile form. We propose that fungal production of JA derivates such as LasA occurs at late infection stages to induce plant JA responses such as cell death, and can facilitate fungal infection.

PMID- 29590433 TI - Interaction of nitric oxide with the components of the plant mitochondrial electron transport chain. AB - Mitochondria are not only major sites for energy production but also participate in several alternative functions, among these generation of nitric oxide (NO), and its different impacts on this organelle, is receiving increasing attention. The inner mitochondrial membrane contains the chain of protein complexes, and electron transfer via oxidation of various organic acids and reducing equivalents leads to generation of a proton gradient that results in energy production. Recent evidence suggests that these complexes are sources and targets for NO. Complex I and rotenone-insensitive NAD(P)H dehydrogenases regulate hypoxic NO production, while complex I also participates in the formation of a supercomplex with complex III under hypoxia. Complex II is a target for NO which, by inhibiting Fe-S centres, regulates reactive oxygen species (ROS) generation. Complex III is one of the major sites for NO production, and the produced NO participates in the phytoglobin-NO cycle that leads to the maintenance of the redox level and limited energy production under hypoxia. Expression of the alternative oxidase (AOX) is induced by NO under various stress conditions, and evidence exists that AOX can regulate mitochondrial NO production. Complex IV is another major site for NO production, which can also be linked to ATP generation via the phytoglobin-NO cycle. Inhibition of complex IV by NO can prevent oxygen depletion at the frontier of anoxia. The NO production and action on various complexes play a major role in NO signalling and energy metabolism. PMID- 29590434 TI - An E2F7-dependent transcriptional program modulates DNA damage repair and genomic stability. AB - The cellular response to DNA damage is essential for maintaining the integrity of the genome. Recent evidence has identified E2F7 as a key player in DNA damage dependent transcriptional regulation of cell-cycle genes. However, the contribution of E2F7 to cellular responses upon genotoxic damage is still poorly defined. Here we show that E2F7 represses the expression of genes involved in the maintenance of genomic stability, both throughout the cell cycle and upon induction of DNA lesions that interfere with replication fork progression. Knockdown of E2F7 leads to a reduction in 53BP1 and FANCD2 foci and to fewer chromosomal aberrations following treatment with agents that cause interstrand crosslink (ICL) lesions but not upon ionizing radiation. Accordingly, E2F7 depleted cells exhibit enhanced cell-cycle re-entry and clonogenic survival after exposure to ICL-inducing agents. We further report that expression and functional activity of E2F7 are p53-independent in this context. Using a cell-based assay, we show that E2F7 restricts homologous recombination through the transcriptional repression of RAD51. Finally, we present evidence that downregulation of E2F7 confers an increased resistance to chemotherapy in recombination-deficient cells. Taken together, our results reveal an E2F7-dependent transcriptional program that contributes to the regulation of DNA repair and genomic integrity.

AB - Introduction: Alcohol Care Management (ACM) is a manualized treatment provided by behavioral health providers working in a primary care team aimed at increasing patients' treatment engagement and decreasing their alcohol use. Research has shown that ACM is effective in reducing alcohol consumption; however, the mechanisms of ACM are unknown. Therefore, the purpose of this study is to examine the mechanisms of change in ACM in the context of a randomized clinical trial evaluating the effectiveness of ACM. Materials and Methods: This study performed secondary data analysis of existing data from a larger study that involved a sample of U.S. veterans (N = 163) who met criteria for current alcohol dependence. Upon enrollment into the study, participants were randomized to receive either ACM or standard care. ACM was delivered in-person or by telephone within the primary care clinic and focused on the use of oral naltrexone and manualized psychosocial support. According to theory, we hypothesized several ACM treatment components that would mediate alcohol consumption outcomes: engagement in addiction treatment, reduced craving, and increased readiness to change. Parallel mediation models were performed by the PROCESS macro Model 4 in SPSS to test study hypotheses. The institutional review boards at each of the participating facilities approved all study procedures before data collection. Results: As hypothesized, results showed that treatment engagement mediated the relation between treatment and both measures of alcohol consumption outcomes, the percentage of alcohol abstinent days, and the percentage of heavy drinking days. Neither craving nor readiness to change mediated the treatment effect on either alcohol consumption outcome. Conclusions: Findings suggest that ACM may be effective in changing drinking patterns partially due to an increase in treatment engagement. Future research may benefit from evaluating the specific factors that underlie increased treatment engagement. The current study provides evidence that alcohol use disorder interventions should aim to increase treatment engagement and reduce barriers to care. PMID- 29590437 TI - Insulin Resistance and beta-Cell Dysfunction in Relation to Cardiometabolic Risk Patterns. AB - Context: Insulin resistance (IR) and beta-cell dysfunction are two major defects synergistically inducing the development of diabetes and related cardiometabolic disorders. Objective: To investigate the independent and joint associations of IR and beta-cell dysfunction with the prevalence of multiple cardiometabolic disorders, including obesity, central obesity, diabetes, dyslipidemia, and hypertension. Design and Settings: A nationally representative population of 93,690 Chinese adults. Main Outcome Measures: IR and beta-cell dysfunction were assessed by the homeostasis model assessment of IR (HOMA-IR) and of beta-cell function (HOMA-B), respectively. Results: High HOMA-IR was independently associated with high prevalence of all estimated cardiometabolic disorders, whereas low HOMA-B was independently associated with high prevalence of diabetes, dyslipidemia, and hypertension but low prevalence of obesity and central obesity. When examined jointly, the associations of HOMA-IR and HOMA-B with multiple cardiometabolic disorders showed different patterns with varying magnitudes. The strongest joint associations were observed for diabetes, with low HOMA-B associated with high prevalence of diabetes regardless of HOMA-IR; joint associations with dyslipidemia and hypertension prevalence appeared to be additive and had moderate changing trends; and low HOMA-B was not associated with high prevalence of obesity or central obesity unless combined with high HOMA-IR. Conclusion: IR was associated with more prevalent cardiometabolic disorders than was beta-cell dysfunction, and combinations of IR and beta-cell dysfunction showed distinct relations with cardiometabolic risk patterns in Chinese adults.

PMID- 29590443 TI - The neurophysiological basis of the discrepancy between objective and subjective sleep during the sleep onset period: an EEG-fMRI study. AB - Subjective perception of sleep is not necessarily consistent with electroencephalography (EEG) indications of sleep. The mismatch between subjective reports and objective measures is often referred to as "sleep state misperception." Previous studies evince that this mismatch is found in both patients with insomnia and in normal sleepers, but the neurophysiological mechanism remains unclear. The aim of the study is to explore the neurophysiological basis of this mechanism, from the perspective of both EEG power and functional magnetic resonance imaging (fMRI) fluctuations. Thirty-six healthy young adults participated in the study. Simultaneous EEG and fMRI recordings were conducted while the participants were trying to fall asleep in an MRI scanner at approximately 9:00 pm. They were awakened after achieving stable N1 or N2 sleep, or after 90 min without falling into stable sleep. Next they were asked to recall their conscious experiences from the moment immediately prior to awakening. Sixty-one instances of scheduled awakenings were collected: 21 of these after having achieved stable stage N2 sleep; 12, during stage N1 sleep; and, 20 during the waking state. Relative to those awakenings without subjective objective discrepancy (n = 27), these awakenings with discrepancy (n = 14) were associated with lower theta power, as well as higher alpha, beta, and gamma power. Moreover, we found that participants who exhibited the discrepancy, compared with those who did not, evinced a higher amplitude of low-frequency fluctuation levels in the prefrontal cortex. These results lend support to the conjecture that the subjective-objective discrepancy is associated with central nervous system hyperarousal. PMID- 29590444 TI - Extremely Delayed Diagnosis of Type II Hereditary Angioedema: Case Report and Review of the Literature. AB - We present a case with extremely late diagnosis of type II hereditary angioedema (HAE). Given recent advances in HAE treatment, we want to bring physician awareness to this condition and aid in earlier detection. HAE is a disorder associated with episodes of angioedema of the face, larynx, lips, abdomen, or extremities. Late diagnosis of HAE can lead to significant morbidity and is severely impairing due to recurring attacks. The diagnosis of HAE is ordinarily made during childhood and adolescence. Delayed diagnoses in early and middle adulthood have been documented in the literature. Gastrointestinal symptoms are common features of HAE and can be misdiagnosed as disease of primary gastrointestinal pathology, such as irritable bowel syndrome, recurrent pancreatitis, or appendicitis. These attacks are characterized by recurrent attacks of subcutaneous and submucosal edema without the presence of urticaria.We present a case of an elderly veteran whose diagnoses was extremely delayed into the eighth decade of life subsequent to unexplained abdominal symptoms. After diagnosis, the patient's symptoms were well controlled with medication due to advances in HAE treatment. To prevent further atypically delayed diagnoses, physicians should consider HAE in patients with recurrent attacks of unexplained abdominal pain. PMID- 29590445 TI - Atlantoaxial Instability in a Patient with Neck Pain and Ankylosing Spondylitis. AB - The purpose of this report is to describe the evaluation and treatment of a patient with neck pain and ankylosing spondylitis who had underlying atlantoaxial instability. The patient was a 31-yr-old man diagnosed with ankylosing spondylitis 1 yr prior who was referred to a physical therapist for the treatment of chronic, worsening low back and hip pain. He also had secondary complaints of neck, upper back, and shoulder pain. The patient worked as a military pilot. As part of the patient's physical examination, a Sharp-Purser test was performed, which was positive for excessive motion. Diagnostic imaging confirmed the atlantoaxial instability; it was also determined that the patient's atlanto occipital joints were fused. Despite evidence of atlantoaxial instability, it was determined the patient would be managed through nonsurgical interventions. The patient was prescribed etanercept by his rheumatologist and the physical therapist developed a comprehensive rehabilitation program that addressed relevant impairments of the spine, hips, and shoulders. At 3 yr following his initial evaluation with the physical therapist, the patient continued to report minimal bodily pain and no limitations in his functional capabilities. Additionally, the patient had earned a high profile flying position with an aggressive flying schedule and he successfully completed his first running marathon. It is important for clinicians to have an understanding of the clinical findings associated with atlantoaxial instability, as these findings provide guidance for diagnostic imaging and specialist referral prior to initiating conservative management strategies, such as physical therapy. PMID- 29590446 TI - Cancer Pain Management Education Rectifies Patients' Misconceptions of Cancer Pain, Reduces Pain, and Improves Quality of Life. AB - Objectives: More than half of the patients have reported improper management of breakthrough cancer pain. Empirical evidence is lacking concerning the effectiveness of cancer pain education on breakthrough pain control. This study aimed to examine the effects of individual pain education on pain control, use of short-acting analgesics for breakthrough pain, quality of life outcomes, and rectification of patients' misconceptions regarding cancer pain. Design: A quasi experimental design was used. In total, 176 (102 inpatients and 74 outpatients) and 163 (93 inpatients and 70 outpatients) cancer patients completed questionnaires on pain intensity, quality of life, use of short-acting medication for breakthrough pain, and misconceptions about cancer pain and opioid use before and immediately and/or seven days after individual pain education. Results: The mean age of the participants was 60.9 years (+/-11.2), and 56.3% were male. The most common cancers were lung cancer (17.0%), colon cancer (15.9%), and breast cancer (12.5%). The subjects' reasons for attrition were conditional deterioration, death, or voluntary withdrawal (N = 13, 7.4%). Following the education, there was a significant reduction in overall pain intensity over 24 hours (P < 0.001). The outpatients showed more use of short-acting analgesics for breakthrough pain. Sleep quality change was most significantly associated with intervention; other quality of life aspects (e.g., general feelings and life enjoyment) also improved. Pain education also significantly reduced misconceptions regarding cancer pain management. Conclusions: The present educational intervention was effective in encouraging short-acting analgesic use for breakthrough pain, improving quality of life outcomes, and rectifying patients' misconceptions about analgesic use.

Edward Hebert School of Medicine just passed its 45th anniversary, opening in 1972. A goal of the medical school, like those nationally, is the production of high-quality physicians. The purpose of this study is to describe the practice characteristics of our USU graduates and to compare data with the national cohort of U.S. MD graduates. Materials and Methods: To accomplish this, we performed a retrospective analysis of U.S. graduates (1980-2009). We used the American Medical Association Physician Masterfile to describe our graduates' current practice profile and compare them with the national cohort. In order to ascertain if USU is meeting our goal to provide high-quality physicians, we also compare our findings with national allopathic school data to norm-reference our results. Results: Our findings indicate that USU graduates contribute to both primary care and specialty care and they practice in all 50 states. USU graduates continue to serve their nation after their obligation is complete, with 64% continuing to practice in federal hospitals and agencies. USU graduates also have a higher board certification rate (90%) than the national cohort (88%). Conclusion: Following our 45th anniversary, we provide continuing evidence that USU is keeping its contract with society. We provide evidence that USU continues to meet its obligation to the nation's health care needs by producing high-quality physicians who serve the country in multiple ways after their military obligation is complete, thus extending the definition of staying power. Our study is not without limitations. First, we could not precisely define the cohort to exclude graduates who still had service obligations. Second, the AMA Physician Masterfile had some missing data fields, so nonresponse or misclassification bias is possible in our results. Study strengths include the long period of time and large number of graduates in each cohort.

AB - Objective: Advances in chemotherapy and chemoradiotherapy have enabled conversion of initially unresectable locally advanced (UR-LA) pancreatic adenocarcinoma (PDAC) to a resectable disease. However, definitive criteria for conversion surgery have not been established. We evaluated the potential of 18F fluorodeoxyglucose positron emission tomography (FDG-PET) to indicate conversion surgery in patients with primary UR-LA PDAC. Methods: Twenty consecutive patients with UR-LA PDAC underwent chemoradiation or chemotherapy followed by assessment with FDG-PET. We defined PET responders (standardized uptake value <3.0) with marked reduction (>80%) of carbohydrate antigen 19-9 as potential candidates for conversion surgery. Outcomes were compared with those of the patients with resectable (R; n = 94) and borderline resectable (BR; n = 37) PDAC. Results: Eight of the 20 patients (40%) were considered PET responders with marked reduction of CA19-9 and received conversion surgery (UR-LAR) 3-9 months (median, 5 months) after the initiation of therapy. Complete resection (R0) was achieved in 7 of 8 patients (87.5%) with UR-LAR. There was no significant difference in R0 rates, morbidity, or mortality among the UR-LAR, R and BR groups. The overall survival (OS) curve was better in the UR-LAR group than in the group that did not receive surgery. There was no significant difference in OS between the UR-LAR and the R or BR groups. Conclusions: FDG-PET could be a potential indicator for conversion surgery in patients with primary UR-LA PDAC and may help in selecting patients who qualify for complete surgical resection and have a promising prognosis. PMID- 29590449 TI - Cancer Incidence in Patients With Acromegaly: A Cohort Study and Meta-Analysis of the Literature. AB - Context: Acromegaly has been associated with increased risk of cancer morbidity and mortality, but research findings remain conflicting and population-based data are scarce. We therefore examined whether patients with acromegaly are at higher risk of cancer. Design: A nationwide cohort study (1978 to 2010) including 529 acromegaly cases was performed. Incident cancer diagnoses and mortality were compared with national rates estimating standardized incidence ratios (SIRs). A meta-analysis of cancer SIRs from 23 studies (including the present one) was performed. Results: The cohort study identified 81 cases of cancer after exclusion of cases diagnosed within the first year [SIR 1.1; 95% confidence interval (CI), 0.9 to 1.4]. SIRs were 1.4 (95% CI, 0.7 to 2.6) for colorectal cancer, 1.1 (95% CI, 0.5 to 2.1) for breast cancer, and 1.4 (95% CI, 0.6 to 2.6) for prostate cancer. Whereas overall mortality was elevated in acromegaly (SIR 1.3; 95% CI, 1.1 to 1.6), cancer-specific mortality was not. The meta-analysis yielded an SIR of overall cancer of 1.5 (95% CI, 1.2 to 1.8). SIRs were elevated for colorectal cancer, 2.6 (95% CI, 1.7 to 4.0); thyroid cancer, 9.2 (95% CI, 4.2 to 19.9); breast cancer, 1.6 (1.1 to 2.3); gastric cancer, 2.0 (95% CI, 1.4 to 2.9); and urinary tract cancer, 1.5 (95% CI, 1.0 to 2.3). In general, cancer SIR was higher in single-center studies and in studies with <10 cancer cases. Conclusions: Cancer incidence rates were slightly elevated in patients with acromegaly in our study, and this finding was supported by the meta-analysis of 23 studies, although it also suggested the presence of selection bias in some earlier studies. PMID- 29590450 TI - The Ups and Downs of Cognitive Function: Neuroticism and Negative Affect Drive Performance Inconsistency. AB - Objectives: Response time inconsistency (RTI)-or trial-to-trial variability in speeded performance-is increasingly recognized as an indicator of transient lapses of attention, cognitive health status, and central nervous system integrity, as well as a potential early indicator of normal and pathological cognitive aging (Hultsch, Strauss, Hunter, & MacDonald, 2008; MacDonald, Li, & Backman, 2009). Comparatively, little research has examined personality predictors of RTI across adulthood. Methods: We evaluated the association between the personality trait neuroticism and RTI in a community-dwelling sample of 317 adults between the ages of 19 to 83 and tested for two indirect pathways through negative affect (NA) and cognitive interference (CI). Results: The personality trait neuroticism predicted greater RTI independent of mean response time performance and demographic covariates; the results were age-invariant. Furthermore, NA (but not CI) accounted for this association and moderated mediation model results indicated that older adults were more vulnerable to the adverse effects of NA. Discussion: Neuroticism predicts greater response time inconsistency irrespective of mean performance and this effect is driven largely by heightened negative emotionality that may be particularly detrimental for older adults.

PMID- 29590452 TI - Exploring the multidisciplinary extent of public health career structures in 12 countries: an exploratory mapping. AB - Background: While much is known about multidisciplinary public health (MDPH) professional practice in the UK which developed particularly in the 1990s, little is known about it in other settings especially low and middle-income countries (LMICs). This study reports on findings of a mapping review of public health career structures and an examination of how multidisciplinary they are in 12 countries. Methods: A 12-element template was used to collect data from relevant websites and key informants with public health experience in the 12 countries. Results: We found that while countries had similarities such as having MDPH professional organizations, there were differences in terms of public health specialty training programmes and openness of senior public health posts at various administrative levels to non-medical professionals. Conclusion: We conclude that there still gaps in MDPH career structures internationally. While this study provides preliminary knowledge on the subject, we recommend further research to inform debates and policies in MDPH professional practice especially in LMICs. PMID- 29590454 TI - Erratum. PMID- 29590453 TI - Infiltrating history into the public health curriculum. AB - The insertion of history into the medical school curriculum has been discussed over a long period of time. But the role of history in the public health curriculum has not been the subject of much discussion, despite the changes in UK public health training and the advent of multidisciplinary public health. This article reviews the history of inserting history into the curriculum in a leading public health postgraduate institution. It discusses the strategies used to secure acceptance for history; the positioning of history within the curriculum both as a core and a special subject; and the different curriculum content and learning approaches which have been used over time. It reviews recent developments in distance learning and the launch of a history Massive Open On line Course. It concludes that no one approach can be recommended for inserting history and that flexibility, persistence, alliances and the willingness to adapt to local circumstances are important. Students themselves are now more receptive to historical approaches and can appreciate the value of a discipline which teaches critical skills of analysis and assessment of evidence. It remains to be discussed how the discipline and such approaches can be transferred into wider professional public health training and at the undergraduate level. PMID- 29590455 TI - Estimates of Tibial Shock Magnitude in Men and Women at the Start and End of a Military Drill Training Program. AB - Introduction: Foot drill is a key component of military training and is characterized by frequent heel stamping, likely resulting in high tibial shock magnitudes. Higher tibial shock during running has previously been associated with risk of lower limb stress fractures, which are prevalent among military populations. Quantification of tibial shock during drill training is, therefore, warranted. This study aimed to provide estimates of tibial shock during military drill in British Army Basic training. The study also aimed to compare values between men and women, and to identify any differences between the first and final sessions of training. Materials and Methods: Tibial accelerometers were secured on the right medial, distal shank of 10 British Army recruits (n = 5 men; n = 5 women) throughout a scheduled drill training session in week 1 and week 12 of basic military training. Peak positive accelerations, the average magnitude above given thresholds, and the rate at which each threshold was exceeded were quantified. Results: Mean (SD) peak positive acceleration was 20.8 (2.2) g across all sessions, which is considerably higher than values typically observed during high impact physical activity. Magnitudes of tibial shock were higher in men than women, and higher in week 12 compared with week 1 of training. Conclusions: This study provides the first estimates of tibial shock magnitude during military drill training in the field. The high values suggest that military drill is a demanding activity and this should be considered when developing and evaluating military training programs. Further exploration is required to understand the response of the lower limb to military drill training and the etiology of these responses in the development of lower limb stress fractures. PMID- 29590456 TI - Hydrogen Peroxide Participates in Perception and Transduction of Cold Stress Signal in Synechocystis. AB - The double mutant DeltakatG/tpx of cyanobacterium Synechocystis sp. strain PCC 6803, defective in the anti-oxidative enzymes catalase (KatG) and thioredoxin peroxidase (Tpx), is unable to grow in the presence of exogenous H2O2. The DeltakatG/tpx mutant is shown to be extremely sensitive to very low concentrations of H2O2, especially when intensified with cold stress. Analysis of gene expression in both wild-type and DeltakatG/tpx mutant cells treated by combined cold/oxidative stress revealed that H2O2 participates in regulation of expression of cold-responsive genes, affecting either signal perception or transduction. The central role of a transmembrane stress-sensing histidine kinase Hik33 in the cold/oxidative signal transduction pathway is discussed. PMID- 29590457 TI - Auxin-cytokinin interactions in the regulation of correlative inhibition in two branched pea seedlings. AB - A model system of 10-12 day-old, two-branched (2-B) pea (Pisum sativum L. cv. Adagumsky) seedlings was used to study the roles of endogenous auxin indole-3 acetic acid (IAA) and cytokinins (CKs) in the interaction between the shoots. The IAA export activity (IEA) from shoots was 2-fold higher in one-branched (1-B) plants with one shoot removed than in the 2-B plants, while tZ-type cytokinin contents in xylem sap were 4-fold greater in the 1-B plants than in 2-B plants. Exogenous 6-benzylaminopurine introduced into the vascular stream of one shoot enhanced its IEA. Therefore, xylem cytokinin appears to control both growth and IEA in branches. In the hypocotyls of 1-B and 2-B plants, IAA contents were equal in both cases, while the levels of tZ-type cytokinins were different. These data do not agree with the well-supported role of auxin in down-regulating CK content. The observed paradox may be explained by assuming that a steady-state IAA level in the hypocotyls is feedback regulated via xylem cytokinin, which controls the delivery of IAA from the shoots. As a result, the level of IAA in the hypocotyl is most likely maintained at a threshold below which a decrease in auxin content can switch on CK synthesis that will increase xylem cytokinin levels, thereby stabilizing the level of IAA in the hypocotyl. Therefore, our results suggest that correlative inhibition in the 2-B pea system is a function of an IAA/CK feedback loop, in which cytokinin essentially acts as a second messenger for IAA.

PMID- 29590460 TI - Coffee consumption and reduced risk of developing type 2 diabetes: a systematic review with meta-analysis. AB - Context: Type 2 diabetes (T2D) is a major health problem worldwide that is associated with increased morbidity and mortality. There is increased interest in the value of different nutrition-based strategies for preventing the development of T2D. Objective: This review aims to cover current knowledge regarding the effects of coffee consumption on development of T2D or modulation of adverse complications. A meta-analysis on coffee consumption and the risk of T2D was conducted. Moreover, bioactive components in coffee, polymorphisms, and potential underlying mechanism(s) in relation to T2D and adverse complications are discussed. Data sources: PubMed was searched up to December 1, 2017, and prospective cohort and nested case-control studies of the association between coffee consumption and T2D risk were selected. Data extraction: Two investigators independently extracted data from included studies. Results: A total of 30 prospective studies with 1 185 210 participants and 53 018 incident T2D cases were included in the meta-analysis. The pooled relative risk (RR) was 0.71 (95% confidence interval [CI], 0.67-0.76) for the highest category of coffee consumption (median consumption, 5 cups/d) vs the lowest category (median consumption, 0 cups/d). The risk of T2D decreased by 6% (RR = 0.94; 95%CI, 0.93 0.95) for each cup-per-day increase in coffee consumption. Results were similar for caffeinated coffee consumption (per additional cup of coffee per day: RR = 0.93; 95%CI, 0.90-0.96) and decaffeinated coffee consumption (corresponding RR = 0.94; 95%CI, 0.90-0.98). Conclusions: Available evidence indicates that coffee consumption is inversely associated with risk of T2D. Possible mechanisms behind this association include thermogenic, antioxidative, and anti-inflammatory effects; modulation of adenosine receptor signaling; and microbiome content and diversity. PMID- 29590459 TI - Systemic haemodynamics in haemodialysis: intradialytic changes and prognostic significance. AB - Background: Although haemodialysis (HD) leads to alterations of systemic haemodynamics that can be monitored using dilution methods, there is a lack of data on the diagnostic and prognostic significance of haemodynamic monitoring during routine HD. Methods: In this multicentre study, we measured cardiac index (CI), access flow (AF) and central blood volume index (CBVI) during a single HD session in stable HD patients (n = 215) using the Transonic HD03 monitor (Transonic, Ithaca, NY, USA). Systemic CI (SCI) was defined as CI corrected for AF. In a subset of patients (n = 82), total end-diastolic volume index (TEDVI) and total ejection fraction (TEF) were derived from dilution curves. Data were correlated with clinical parameters, cardiac biomarkers and bioimpedance measurements (body composition monitor; Fresenius Medical Care, Homburg, Germany). Mortality was assessed prospectively after a median follow-up of 2.6 years. Results: Median CI, CBVI and AF were 2.8 L/min/m2 (interquartile range 2.4 3.4), 15 mL/kg (14.5-15.7) and 980 mL/min (740-1415), respectively, at the beginning of HD. At the end of HD, CI, CBVI and AF significantly fell by -10% ( 22 to 3, P < 0.0001), -9% (-23 to 3, P < 0.0001) and -4% (-13 to 5, P = 0.0004), respectively. Peripheral resistance (PR) increased slightly (P = 0.01) and blood pressure fell by -6/-3 mmHg to 128/63 mmHg (P < 0.0001). Independent predictors of DeltaCI were age and ultrafiltration rate, whereas AF, overhydration and PR were protective. TEF was strongly associated with mortality [area under the dilution curve 0.77, P < 0.0001], followed by TEDVI (0.72, P = 0.0002) and SCI (0.60, P = 0.02). Conclusions: HD leads to a reduction of CI due to ultrafiltration. Haemodynamic monitoring identifies a significant number of HD patients with cardiac impairment that are at risk for increased mortality. PMID- 29590462 TI - The Epidemiology of Social Isolation: National Health & Aging Trends Study. AB - Objectives: Social isolation among older adults is an important but under recognized risk for poor health outcomes. Methods are needed to identify subgroups of older adults at risk for social isolation. Methods: We constructed a typology of social isolation using data from the National Health and Aging Trends Study (NHATS) and estimated the prevalence and correlates of social isolation among community-dwelling older adults. The typology was formed from four domains: living arrangement, core discussion network size, religious attendance, and social participation. Results: In 2011, 24% of self-responding, community dwelling older adults (65+ years), approximately 7.7 million people, were characterized as socially isolated, including 1.3 million (4%) who were characterized as severely socially isolated. Multinomial multivariable logistic regression indicated that being unmarried, male, having low education, and low income were all independently associated with social isolation. Black and Hispanic older adults had lower odds of social isolation compared to White older adults, after adjusting for covariates. Discussion: Social isolation is an important and potentially modifiable risk that affects a significant proportion of the older adult population. PMID- 29590461 TI - Prognostic value of contrast enhancement and FLAIR for survival in newly diagnosed glioblastoma treated with and without bevacizumab: results from ACRIN 6686. AB - Background: ACRIN 6686/RTOG 0825 was a phase III trial of conventional chemoradiation plus adjuvant temozolomide with bevacizumab or without (placebo) in newly diagnosed glioblastoma. This study investigated whether changes in contrast-enhancing and fluid attenuated inversion recovery (FLAIR)-hyperintense tumor assessed by central reading prognosticate overall survival (OS). Methods: Two hundred eighty-four patients (171 men; median age 57 y, range 19-79; 159 on bevacizumab) had MRI at post-op (baseline) and pre-cycle 4 of adjuvant temozolomide (22 wk post chemoradiation initiation). Four central readers measured bidimensional lesion enhancement (2D-T1) and FLAIR hyperintensity at both time points. Changes from baseline to pre-cycle 4 for both markers were dichotomized (increasing vs non-increasing). Cox proportional hazards model and Kaplan-Meier survival estimates were used for inference. Results: Adjusting for treatment, increasing 2D-T1 (n = 262, hazard ratio [HR] = 2.07, 95% CI: 1.48 2.91, P < 0.0001) and FLAIR (n = 273, HR = 1.75, 95% CI: 1.26-2.41, P = 0.0008) significantly predicted worse OS. Median OS (days) was significantly shorter for patients with increasing versus non-increasing 2D-T1 for both bevacizumab (443 vs 535, P = 0.004) and placebo (526 vs 887, P = 0.001). Median OS was significantly shorter for patients with increasing versus non-increasing FLAIR for placebo (595 vs 872, P = 0.001), and trended similarly for bevacizumab (499 vs 535, P = 0.0935). Adjusting for 2D-T1 and treatment, increasing FLAIR represented significantly higher risk for death (HR = 1.59 [1.11-2.26], P = 0.01). Conclusion: Increased 2D-T1 significantly predicts worse OS in both treatment groups, implying absence of a substantial proportion of pseudoprogression 22 weeks after initiation of standard therapy. FLAIR adds value beyond 2D-T1 in predicting OS, potentially addressing the pseudoresponse effect by substratifying bevacizumab-treated patients with non-increasing 2D-T1. PMID- 29590463 TI - Diagnosing IgA Vasculitis in the Active Duty Population: The Importance of Early Diagnosis and Proper Biopsy Site Selection. AB - Immunoglobulin A associated vasculitis (IgAV), formerly called Henoch-Schonlein purpura, is a small vessel vasculitis which typically presents with upper and lower extremity palpable purpura and abdominal pain. It is the most common vasculitis in children, and is less common in adults. However, newer evidence suggests the incidence within the adult population is higher than previously reported. This case study demonstrates an adult military recruit presenting with new onset IgAV shortly after basic training. He noted a preceding upper respiratory tract infection, which is a common finding in those presenting with IgAV. The diagnosis was made by clinical findings, histopathological results and direct immunofluorescence. Adults tend to develop more necrotic and bullous lesions when compared with children. This can skew histopathology and direct immunofluorescence. There is no clear consensus in current literature for whether to obtain lesional or perilesional biopsies. Such recommendations could be particularly advantageous for adults given the abnormal lesions. This case study addresses the incidence of IgAV within the adult population, diagnostic criteria, long-term sequalea of IgAV, and the importance of a proper biopsy sight when making the diagnosis. PMID- 29590464 TI - Establishing normal values for pediatric nighttime sleep measured by actigraphy: a systematic review and meta-analysis. AB - Background: Despite the widespread use of actigraphy in pediatric sleep studies, there are currently no age-related normative data. Objectives: To systematically review the literature, calculate pooled mean estimates of actigraphy-derived pediatric nighttime sleep variables and to examine the magnitude of change with age. Methods: A systematic search was performed across eight databases of studies that included at least one actigraphy sleep variable from healthy children aged 0 18 years. Data suitable for meta-analysis were confined to ages 3-18 years with seven actigraphy variables analyzed using random effects meta-analysis and meta regression performed using age as a covariate. Results: In total, 1334 articles did not meet inclusion criteria; 87 had data suitable for review and 79 were suitable for meta-analysis. Pooled mean estimates for overnight sleep duration declined from 9.68 hours (3-5 years age band) to 8.98, 8.85, 8.05, and 7.4 for age bands 6-8, 9-11, 12-14, and 15-18 years, respectively. For continuous data, the best-fit (R2 = 0.74) equation for hours over the 0-18 years age range was 9.02 - 1.04 * [(age/10)^2 - 0.83]. There was a significant curvilinear association between both sleep onset and offset with age (p < .001). Sleep latency was stable at 19.4 min per night. There were significant differences among the older age groups between weekday and weekend/nonschool days (18 studies). Total sleep time in 15-18 years old was 56 min longer, and sleep onset and offset almost 1 and 2 hours later, respectively, on weekend or nonschool days. Conclusion: These normative values have potential application to assist the interpretation of actigraphy measures from nighttime recordings across the pediatric age range, and aid future research. PMID- 29590466 TI - Beyond One Hundred: A Cohort Analysis of Italian Centenarians and Semi supercentenarians. AB - Although the increase in the number of centenarians is well documented today in countries with advanced demographic data, the same is not true for those aged 105 and over. The first aim of this paper, was to analyze the demographic characteristics of the 4,626 validated semi-super and 102 supercentenarians for the cohorts born between 1896 and 1910, referring to Italian Semi Supercentenarians Survey (SSC). Then, starting from this data and from the survival histories in old ages - reconstructed by Vincent's Extinct - Cohort Method - for the cohorts born between 1870 and 1904, the most important aim was to analyze longevity history and the trend of gender gap of the Italian oldest cohorts beyond 100 years old. The Italian centenarians and semi supercentenarians increase from the first to the last cohort is due to the survival rise in old ages and the increase in the gender gap at extreme ages depends on the higher survival of women than men after 60 years old. Around 110 112 for both genders (for women in particular) a kind of resistance to further progress seems to appear in our analysis as in more recent studies on supercentenarians. PMID- 29590465 TI - Population description and clinical response assessment for spinal metastases: part 2 of the SPIne response assessment in Neuro-Oncology (SPINO) group report. AB - Background: Approximately 40% of metastatic cancer patients will develop spinal metastases. The current report provides recommendations for standardization of metrics used for spinal oncology patient population description and outcome assessment beyond local control endpoints on behalf of the SPIne response assessment in Neuro-Oncology (SPINO) group. Methods: The SPINO group survey was conducted in order to determine the preferences for utilization of clinician based and patient-reported outcome measures for description of patients with spinal metastases. Subsequently, ClinicalTrials.gov registry was searched for spinal oncology clinical trials, and measures for patient description and outcome reporting were identified for each trial. These two searches were used to identify currently used descriptors and instruments. A literature search was performed focusing on the measures identified in the survey and clinical trial search in order to assess their validity in the metastatic spinal tumor patient population. References for this manuscript were identified through PubMed and Medline searches. Results: Published literature, expert survey, and ongoing clinical trials were used to synthesize recommendations for instruments for reporting of spinal stability, epidural tumor extension, neurological and functional status, and symptom severity. Conclusions: Accurate description of patient population and therapy effects requires a combination of clinician-based and patient-reported outcome measures. The current report provides international consensus recommendations for the systematic reporting of patient- and clinician reported measures required to develop trials applicable to surgery for spinal metastases and postoperative spine stereotactic body radiotherapy (SBRT). PMID- 29590467 TI - A Retrospective Study of Neonatal Outcome in Preeclampsia at the University Hospital of the West Indies: A Resource-limited Setting. AB - Aim: This study aimed to determine the outcome of neonates born to women with preeclampsia at the University Hospital of the West Indies (UHWI). Methods: This was a retrospective descriptive study looking at the outcome of all babies born to women with preeclampsia and control babies born to normotensive women at the UHWI over a 20-month period. Maternal and neonatal demographic data and course of admission for admitted neonates were recorded. Descriptive analyses were performed. Results: Neonates born to women with preeclampsia were more likely to be low birth weight [odds ratio (OR = 2.8; confidence interval (CI): 2.2-3.5], small for gestational age (OR = 2.3; CI: 1.9-2.9) or premature (OR = 2.5; CI: 2.0 3.0). They had a lower mean 5 min Apgar score than babies born to normotensive women p<0.05. They were also more likely to be admitted to the neonatal unit 67 (59%) compared with neonates of normotensive women 13 (13%) p<0.001. The main reason for admission was prematurity. Eighteen neonates, all born to women with preeclampsia, died, and the main cause of death was prematurity. Conclusion: Adverse neonatal outcome was noted in neonates born to women with preeclampsia, and this was predominantly related to prematurity and its complications. PMID- 29590468 TI - Re-experiencing Violence across the Life Course: Histories of Childhood Maltreatment and Elder Abuse Victimization. AB - Objectives: This study primarily examines the associations between histories of childhood maltreatment (i.e., neglect, emotional, physical, and sexual abuse) and elder abuse victimization and explores whether gender moderates the associations. Methods: We conducted a secondary data analysis of 5,968 older adults (mean age = 71 years) based on data from the Wisconsin Longitudinal Study (2010-2011). Using retrospective self-reports of childhood and current (past 12 months) victimization experiences, logistic regression analyses were conducted to estimate the effects of early-life adversities on the likelihood of elder abuse victimization. Results: Results indicate that childhood emotional abuse and childhood sexual abuse were associated with greater risk of being abused as older adults, after controlling for childhood and adult background factors. We also found that the effect of childhood sexual abuse on elder abuse victimization was weaker for women than men. Discussion: Findings suggest that the phenomenon of revictimization may occur not only in early and middle adulthood, but also in late life. To advance our understanding of victimization across the life course, future research on root causes of elder abuse should include histories of child abuse. PMID- 29590469 TI - Situational and Demographic Factors in the Sudden Growth of Pall Mall, 2002-2014. AB - Objective: Pall Mall gained significant brand share in the cigarette market between 2002 and 2013. We sought to determine whether demographic shifts occurred among the participants reporting Pall Mall as their usual brand during this time span. Method: We examined National Survey of Drug Use and Health (NSDUH) data from 2002-2014. Demographic characteristics included age, education, ethnicity, income, and cigarette use (cigarettes per day, daily/non-daily smoking, and nicotine dependence). We also examined RJ Reynolds investor reports and shareholder documents to determine the impact of tobacco marketing on the growth of Pall Mall. Results: Over 2002-2014, Pall Mall has gained among smokers 26 to 34 years of age. More Pall Mall smokers in 2014 report higher incomes (over $75000), and also report lower scores on measures of cigarette dependence, compared to 2002. Pall Mall smokers over time seem to share characteristics of premium cigarette brands smokers. Conclusion: The profile of the typical Pall Mall smoker has changed as the brand has gained market share. An association exists between brand positioning and economic forces, which has contributed to an increase in the market share for Pall Mall. Implications: It is well known that cigarette marketing drives the sale of tobacco products. The growth in the market share of Pall Mall serves as an excellent example to demonstrate how economic uncertainty paired with brand positioning and advertising worked together to serve as a catalyst for the rapid growth observed for this brand. This paper also looked at various demographic changes that occurred among Pall Mall smokers over a 12 year period and compared them to smokers of all other cigarette brands. The results of this analysis demonstrate the importance of monitoring trends over time among cigarette smokers. PMID- 29590470 TI - Accuracy of Bioelectrical Impedance Analysis in Estimated Longitudinal Fat-Free Mass Changes in Male Army Cadets. AB - Introduction: Bioelectrical impedance analysis (BIA) is a practical and rapid method for making a longitudinal analysis of changes in body composition. However, most BIA validation studies have been performed in a clinical population and only at one moment, or point in time (cross-sectional study). The aim of this study is to investigate the accuracy of predictive equations based on BIA with regard to the changes in fat-free mass (FFM) in Brazilian male army cadets after 7 mo of military training. The values used were determined using dual-energy X ray absorptiometry (DXA) as a reference method. Materials and Methods: The study included 310 male Brazilian Army cadets (aged 17-24 yr). FFM was measured using eight general predictive BIA equations, with one equation specifically applied to this population sample, and the values were compared with results obtained using DXA. The student's t-test, adjusted coefficient of determination (R2), standard error of estimation (SEE), Lin's approach, and the Bland-Altman test were used to determine the accuracy of the predictive BIA equations used to estimate FFM in this population and between the two moments (pre- and post-moment). Results: The FFM measured using the nine predictive BIA equations, and determined using DXA at the post-moment, showed a significant increase when compared with the pre-moment (p < 0.05). All nine predictive BIA equations were able to detect FFM changes in the army cadets between the two moments in a very similar way to the reference method (DXA). However, only the one BIA equation specific to this population showed no significant differences in the FFM estimation between DXA at pre- and post-moment of military routine. All predictive BIA equations showed large limits of agreement using the Bland-Altman approach. Conclusion: The eight general predictive BIA equations used in this study were not found to be valid for analyzing the FFM changes in the Brazilian male army cadets, after a period of approximately 7 mo of military training. Although the BIA equation specific to this population is dependent on the amount of FFM, it appears to be a good alternative to DXA for assessing FFM in Brazilian male army cadets.

AB - Objectives: Drawing on the "Health and Aging in Africa: A Longitudinal Study of an INDEPTH community in South Africa" (HAALSI) baseline survey, we present data on older adults' social networks and receipt of social support in rural South Africa. We examine how age and gender differences in social network characteristics matched with patterns predicted by theories of choice- and constraint-based network contraction in older adults. Method: We used regression analysis on data for 5,059 South African adults aged 40 and older. Results: Older respondents reported fewer important social contacts and less frequent communication than their middle-aged peers, largely due to fewer nonkin connections. Network size difference between older and younger respondents was greater for women than for men. These gender and age differences were explicable by much higher levels of widowhood among older women compared to younger women and older men. There was no evidence for employment-related network contraction or selective retention of emotionally supportive ties. Discussion: Marriage related structural constraints impacted on older women's social networks in rural South Africa, but did not explain choice-based network contraction. These findings suggest that many older women in rural Africa, a growing population, may have an unmet need for social support.

AB - Introduction: The association between disability and cause of death in Veterans with service-connected disabilities has not been studied. The objective of this study was to compare age at death, military service and disability characteristics, including disability rating, and cause of death by year of birth. We also examined cause of death for specific service-connected conditions. Materials and methods: This study used information from the VETSNET file, which is a snapshot of selected items from the Veterans Benefits Administration corporate database. We also used the National Death Index (NDI) for Veterans which is part of the VA Suicide Data Repository. In VETSNET, there were 758,324 Veterans who had a service-connected condition and died between the years 2004 and 2014. Using the scrambled social security number to link the two files resulted in 605,493 (80%) deceased Veterans. Age at death, sex, and underlying cause of death were obtained from the NDI for Veterans and military service characteristics and types of disability were acquired from VETSNET. We constructed age categories corresponding to period of service; birth years 1938 and earlier corresponded to Korea and World War II ("oldest"), birth years 1939 1957 to the Vietnam era ("middle"), and birth years 1958 and later to post Vietnam, Gulf War, and the more recent conflicts in Iraq and Afghanistan ("youngest"). Results: Sixty-two percent were in the oldest age category, 34% in the middle group, and 4% in the youngest one. The overall age at death was 75 +/- 13 yr. Only 1.6% of decedents were women; among women 25% were in the youngest age group, while among men only 4% were in the youngest group. Most decedents were enlisted personnel, and 60% served in the U.S. Army. Nearly 61% had a disability rating of >50% and for the middle age group 54% had a disability rating of 100%. The most common service-connected conditions were tinnitus, hearing loss, and post-traumatic stress disorder (PTSD). In the oldest group, nearly half of deaths were due to cancer or cardiovascular conditions and <2% were due to external causes. In the youngest group, cardiovascular disease and cancer accounted for about 1/3 of deaths, whereas external causes or deaths due to accidents, suicide, or assault accounted for nearly 33% of deaths. For Veterans with service-connected PTSD or major depression; 6.5% of deaths were due to external causes whereas for Veterans without these conditions, only 3.1% were due to external causes. Conclusion: The finding of premature death due to external causes in the youngest age group as well as the finding of higher proportions of external causes in those with PTSD or major depression should be of great concern to those who care for Veterans. PMID- 29590475 TI - Tinnitus and Associated Handicaps in the French Mountain Artillery: Assessment by the Tinnitus Handicap Inventory. AB - Introduction: Tinnitus and associated handicap related to acoustic trauma sequelae have never been assessed in the French artillery. Although impulsive noise exposure to firearms and canons are thought to increase prevalence of tinnitus among soldiers, recent studies demonstrating this fact are missing. Materials and Methods: Here, a representative sample of 389 soldiers from an operational mountain artillery regiment was surveyed. Soldiers personally concerned by tinnitus were invited to fill in a questionnaire. We assessed tinnitus and the associated handicap using a French translation of the Tinnitus Handicap Inventory (THI). Questions about attention/concentration problems, impaired speech hearing and understanding, sleep disorders, social and familial tension, irritability, depression, and tiredness as linked to tinnitus were the core of the questionnaire. Results: Soldiers that completed the THI (n = 73, 19%) had a mean THI score of 18 +/- 17, this mean score corresponded to a mild handicap. At this grade, tinnitus should be easily masked and should not interfere with daily activities. The percentage of soldiers concerned by tinnitus was slightly higher in the older age class, but there was no significant difference of THI scores between the different age classes. The most reported handicaps were attention/concentration problems, impaired speech hearing, and understanding. Among the THI fillers, eight soldiers (11%) had THI scores >36, indicating a moderate to severe handicap. Conclusion: Despite a mild tinnitus handicap, the percentage of people concerned by tinnitus in this regiment is higher (19%) than that in the estimated percentage of general population of European countries (about 10%). It should be of interest to replicate this type of study from other regiments and from other countries. Education and good fitting of hearing protection for prevention of acoustic trauma sequelae should still be encouraged. PMID- 29590474 TI - The association of obesity with disease activity, functional ability and quality of life in early rheumatoid arthritis: data from the Early Rheumatoid Arthritis Study/Early Rheumatoid Arthritis Network UK prospective cohorts. AB - Objectives: To examine associations between BMI and disease activity, functional ability and quality of life in RA. Methods: Data from two consecutive, similarly designed UK multicentre RA inception cohorts were used: the Early RA Study (ERAS) and the Early RA Network (ERAN). Recruitment figures/median follow-up for the ERAS and ERAN were 1465/10 years (maximum 25 years), and 1236/6 years (maximum 10 years), respectively. Standard demographic and clinical variables were recorded at baseline and annually. Multilevel piecewise longitudinal models with a change point at 2 years were used with the 28-joint DAS (DAS28), ESR, HAQ and 36-item Short Form Health Survey (SF-36) physical (PCS) and mental (MCS) components as dependent variables. BMI was examined in separate models as both continuous and categorical variables (based on World Health Organization definitions) and up to 5 years from disease onset. Results: BMI data from 2386 newly diagnosed RA patients (11 348 measures) showed an increase in BMI of 0.27 U annually (95% CI 0.21, 0.33). Baseline obesity was associated with a significant reduction in the odds of achieving a low year 2 DAS28 [OR 0.52 (95% CI 0.41, 0.650)]. At year 2, HAQ and SF-36 PCS scores were significantly worse but not at year 5 in patients obese at baseline. Obesity at year 2 was associated with higher DAS28 scores at year 2, but not at year 5, and also associated with significantly higher HAQ and SF-36 PCS scores at years 2 and 5. Conclusion: Obesity prevalence is rising in early RA and associates with worse disease activity, function and health-related quality of life, with a significant negative impact on achieving a low DAS28. The data argue strongly for obesity management to become central to treatment strategies in RA.

AB - Background: Psychosis risk is associated with striatal dysfunction, including a previous behavioral study that found that psychosis risk is associated with impaired performance on a probabilistic category learning task (PCLT; ie, the Weather Prediction Task), a task strongly associated with striatal activation. The current study examined whether psychosis risk based on symptom levels was associated with both poor behavioral performance and task-related physiological dysfunction in specific regions of the striatum while performing the PCLT. Methods: There were 2 groups of participants: psychosis risk (n = 21) who had both (a) extreme levels of self-reported psychotic-like beliefs and experiences and (b) interview-rated current attenuated psychotic symptoms (APS); and a comparison group (n = 20) who had average levels of self-reported psychotic-like beliefs and experiences. Participants completed the PCLT during fMRI scanning. Results: The current research replicated previous work finding behavioral PCLT deficits at the end of the task in psychosis risk. Furthermore, as expected, the psychosis risk group exhibited decreased striatal activation on the task, especially in the associative striatum. The psychosis risk group also displayed decreased activation in a range of cortical regions connected to the associative striatum. In contrast, the psychosis risk group exhibited greater activation predominantly in cortical regions not connected to the associative striatum. Conclusions: Psychosis risk was associated with both behavioral and striatal dysfunction during performance on the PCLT, suggesting that behavioral and imaging measures using this task could be a marker for psychosis risk. PMID- 29590477 TI - RNA-splicing factor SART3 regulates translesion DNA synthesis. AB - Translesion DNA synthesis (TLS) is one mode of DNA damage tolerance that uses specialized DNA polymerases to replicate damaged DNA. DNA polymerase eta (Poleta) is well known to facilitate TLS across ultraviolet (UV) irradiation and mutations in POLH are implicated in skin carcinogenesis. However, the basis for recruitment of Poleta to stalled replication forks is not completely understood. In this study, we used an affinity purification approach to isolate a Poleta-containing complex and have identified SART3, a pre-mRNA splicing factor, as a critical regulator to modulate the recruitment of Poleta and its partner RAD18 after UV exposure. We show that SART3 interacts with Poleta and RAD18 via its C-terminus. Moreover, SART3 can form homodimers to promote the Poleta/RAD18 interaction and PCNA monoubiquitination, a key event in TLS. Depletion of SART3 also impairs UV induced single-stranded DNA (ssDNA) generation and RPA focus formation, resulting in an impaired Poleta recruitment and a higher mutation frequency and hypersensitivity after UV treatment. Notably, we found that several SART3 missense mutations in cancer samples lessen its stimulatory effect on PCNA monoubiquitination. Collectively, our findings establish SART3 as a novel Poleta/RAD18 association regulator that protects cells from UV-induced DNA damage, which functions in a RNA binding-independent fashion. PMID- 29590479 TI - Stakeholder perspectives on costs and resource expenditures: tools for addressing economic issues most relevant to patients, providers, and clinics. AB - Cost and other resources required are often primary considerations in whether a potential program or policy will be adopted or implemented and an important element in determining value. However, few economic analyses are conducted from the perspective of patient/family or small-scale stakeholders such as local clinics. We outline and discuss alternative cost assessment and resource expenditures options from the perspective of these small, proximal stakeholders. The perspective of these persons differs from larger societal or health plan perspectives, and often differs across individuals in terms of what they value and the types of expenditures about which they are concerned. We discuss key features of the perspectives of patients, health care clinics, and local leaders, and present brief examples and sample templates for collection of consumer/stakeholder relevant cost and return on investment issues. These tools can be used prospectively and iteratively during program planning, intervention delivery, summative analysis, and preparation for dissemination stages. There is an important need for this type of feasible, pragmatic, rapid, and iterative cost and resource expenditure analysis directly relevant to patients/families, small local stakeholders and their organizations. Future research on and use of these approaches is recommended. PMID- 29590481 TI - Letter: Navigation-Linked Heads-Up Display in Intracranial Surgery: Early Experience. PMID- 29590480 TI - Anatomic predictors of response and mechanism of action of upper airway stimulation therapy in patients with obstructive sleep apnea. AB - Study Objectives: Upper airway stimulation has been shown to be an effective treatment for some patients with obstructive sleep apnea. However, the mechanism by which hypoglossal nerve stimulation increases upper airway caliber is not clear. Therefore, the objective of this study was to identify the mechanism of action of upper airway stimulation. We hypothesized that, with upper airway stimulation, responders would show greater airway opening in the retroglossal (base of the tongue) region, greater hyoid movement toward the mandible, and greater anterior motion in the posterior, inferior region of the tongue compared with nonresponders. Methods: Seven participants with obstructive sleep apnea who had been successfully treated with upper airway stimulation (responders) and six participants who were not successfully treated (nonresponders) underwent computed tomography imaging during wakefulness with and without hypoglossal nerve stimulation. Responders reduced their apnea-hypopnea index (AHI) by 22.63 +/- 6.54 events per hour, whereas nonresponders had no change in their AHI (0.17 +/- 14.04 events per hour). We examined differences in upper airway caliber, the volume of the upper airway soft tissue structures, craniofacial relationships, and centroid tongue and soft palate movement between responders and nonresponders with and without hypoglossal nerve stimulation. Results: Our data indicate that compared with nonresponders, responders had a smaller baseline soft palate volume and, with stimulation, had (1) a greater increase in retroglossal airway size; (2) increased shortening of the mandible-hyoid distance; and (3) greater anterior displacement of the tongue. Conclusions: These results suggest that smaller soft palate volumes at baseline and greater tongue movement anteriorly with stimulation improve the response to upper airway stimulation. PMID- 29590482 TI - Using Neuroscience to Inform Tobacco Control Policy. AB - Background and Aims: Techniques employed in the field of neuroscience, such as eye-tracking, electroencephalography, and functional magnetic resonance imaging, have been important in informing our understanding of the cognitive mechanisms underlying tobacco smoking. These techniques are now increasingly being used to investigate the likely impact of tobacco control measures. Methods: In this narrative review, we outline the value of these methodological approaches in answering policy relevant tobacco control research questions, with a particular focus on their use in examining the impact of standardised cigarette packaging and health warnings. We also examine the limitations of these methodologies and provide examples of how these technologies can be used to answer other policy relevant questions. Results: We argue that neuroscience techniques can provide more objective evidence of the impacts of policy measures, allow investigation where it is not possible to conduct behavioural manipulations and facilitate a deeper understanding of the cognitive mechanisms underlying the impacts of tobacco control policies such as standardised packaging, health warnings, point of sale displays and mass media campaigns. Conclusions: Rather than replacing more traditional methods of examining tobacco control measures, such as observational experiments, surveys and questionnaires, neuroscience techniques can complement and extend these methods. Implications: Neuroscience techniques can provide more objective evidence of the impacts of policy measures, allow investigation where it is not possible to conduct behavioural manipulations and facilitate a deeper understanding of the cognitive mechanisms underlying the impacts of tobacco control policies. Rather than replacing more traditional methods of examining tobacco control measures, such as observational experiments, surveys and questionnaires, neuroscience techniques can complement and extend these methods. PMID- 29590483 TI - Building Capacity for Complementary and Integrative Medicine Through a Large, Cross-Agency, Acupuncture Training Program: Lessons Learned from a Military Health System and Veterans Health Administration Joint Initiative Project. AB - Introduction: Complementary and integrative medicine (CIM) use in the USA continues to expand, including within the Military Health System (MHS) and Veterans Health Administration (VHA). To mitigate the opioid crisis and provide additional non-pharmacological pain management options, a large cross-agency collaborative project sought to develop and implement a systems-wide curriculum, entitled Acupuncture Training Across Clinical Settings (ATACS). Materials and Methods: ATACS curriculum content and structure were created and refined over the course of the project in response to consultations with Subject Matter Experts and provider feedback. Course content was developed to be applicable to the MHS and VHA environments and training was open to many types of providers. Training included a 4-hr didactic and "hands on" clinical training program focused on a single auricular acupuncture protocol, Battlefield Acupuncture. Trainee learning and skills proficiency were evaluated by trainer-observation and written examination. Immediately following training, providers completed an evaluation survey on their ATACS experience. One month later, they were asked to complete another survey regarding their auricular acupuncture use and barriers to use. The present evaluation describes the ATACS curriculum, faculty and trainee characteristics, as well as trainee and program developer perspectives. Results: Over the course of a 19-mo period, 2,712 providers completed the in-person, 4-hr didactic and hands-on clinical training session. Due to the increasing requests for training, additional ATACS faculty were trained. Overall, 113 providers were approved to be training faculty. Responses from the trainee surveys indicated high satisfaction with the ATACS training program and illuminated several challenges to using auricular acupuncture with patients. The most common reported barrier to using auricular acupuncture was the lack of obtaining privileges to administer auricular acupuncture within clinical practice. Conclusion: The ATACS program provided a foundational template to increase CIM across the MHS and VHA. The lessons learned in the program's implementation will aid future CIM training programs and improve program evaluations. Future work is needed to determine the most efficient means of improving CIM credentialing and privileging procedures, standardizing and adopting uniform CIM EHR codes and documentation, and examining the effectiveness of CIM techniques in real-world settings.

PMID- 29590486 TI - Age, burnout and physical and psychological work ability among nurses. AB - Background: The ageing of the US labour force highlights the need to examine older adults' physical and psychological ability to work, under varying levels of occupational burnout. Aims: To examine how age and burnout interact in predicting physical and psychological work ability. Methods: Using a cohort of actively working nurses, we assessed factors on the Work Ability Index at 12-month follow up and determined how these were related to age and exhaustion-related burnout at baseline. Results: The study group consisted of 402 nurses aged 25-67 (mean = 41.7). Results indicated age by burnout interactions in which decrements in physical work ability with greater age were observed at all but the lowest level of burnout (1.5 SD below mean: beta = -0.14, 95% CI -0.36, 0.07; 1 SD below: beta = -0.23, 95% CI -0.39, -0.06; mean: beta = -0.39, 95% CI -0.50, -0.29; 1 SD above: beta = -0.56, 95% CI -0.70, -0.42; 1.5 SD above: beta = -0.64, 95% CI 0.83, -0.46). In contrast, we observed decrements in psychological work ability with age at higher levels of burnout only (1 SD above: beta = -0.20, 95% CI 0.35, -0.05; 1.5 SD above: beta = -0.30, 95% CI -0.49, -0.11); at lower levels of burnout, older age was associated with improvements in this (1 SD below: beta = 0.19, 95% CI 0.03, 0.35; 1.5 SD below: beta = 0.29, 95% CI 0.08, 0.50). Conclusions: Findings indicated physical and psychological dimensions of work ability that differed by age and occupational burnout. This emphasizes the need for interventions to reduce burnout and to address age-related strengths and vulnerabilities relating to physical and psychological work ability. PMID- 29590487 TI - Psychological Flexibility and Set-Shifting Among Veterans Participating in a Yoga Program: A Pilot Study. AB - Introduction: Trauma-focused psychotherapies do not meet the needs of all veterans. Yoga shows some potential in reducing stress and perhaps even PTSD in veterans, although little is understood about the mechanisms of action. This study identifies preliminary correlates of change in PTSD and perceived stress for veterans participating in yoga. Materials and methods: Nine veterans (seven males and two females) were recruited from an existing clinical yoga program and observed over 16 wk. Severity of PTSD symptoms (PCL-5) and perceived stress (PSS 10) were collected at baseline and weeks 4, 6, 8, and 16. Psychological flexibility (AAQ-II) and set-shifting (ratio of trail making test A to B) were collected at baseline and at week 6. Subjects attended yoga sessions freely, ranging from 1 to 23 classes over the 16 weeks. The Stanford University Institutional Review Board approved this research protocol. Results: Self reported PTSD symptoms significantly reduced while perceived stress did not. Lower baseline set-shifting predicted greater improvements in PTSD between baseline and 4 weeks; early improvements in set-shifting predicted overall reduction in PTSD. Greater psychological flexibility was associated with lower PTSD and perceived stress; more yoga practice, before and during the study, was associated with greater psychological flexibility. Other predictors were not supported. Conclusions: In a small uncontrolled sample, psychological flexibility and set-shifting predicted changes in PTSD symptoms in veterans participating in a clinical yoga program, which supports findings from prior research. Future research should include an active comparison group and record frequency of yoga practiced outside formal sessions.

To greatly speed up sleep staging without compromising accuracy, we developed a novel framework for performing real-time automatic sleep stage classification. The client-server architecture adopted here provides an end-to end solution for anonymizing and efficiently transporting polysomnography data from the client to the server and for receiving sleep stages in an interoperable fashion. The framework intelligently partitions the sleep staging task between the client and server in a way that multiple low-end clients can work with one server, and can be deployed both locally as well as over the cloud. The framework was tested on four datasets comprising ~1700 polysomnography records (~12000 hr of recordings) collected from adolescents, young, and old adults, involving healthy persons as well as those with medical conditions. We used two independent validation datasets: one comprising patients from a sleep disorders clinic and the other incorporating patients with Parkinson's disease. Using this system, an entire night's sleep was staged with an accuracy on par with expert human scorers but much faster (~5 s compared with 30-60 min). To illustrate the utility of such real-time sleep staging, we used it to facilitate the automatic delivery of acoustic stimuli at targeted phase of slow-sleep oscillations to enhance slow wave sleep. PMID- 29590493 TI - Longitudinal Twin Study of Subjective Health: Differences in Genetic and Environmental Components of Variance Across Age and Sex. AB - Objective: The current analysis examines sex differences in longitudinal changes in genetic and environmental influences on three measures of subjective health. Method: Sample includes 7372 twins (mean intake age = 73.22) with up to 8 waves of measurement (mean = 3.1). Three subjective health (SH) items were included: general self-rated health (SRH), health compared to age peers (COMP), and impact of health on activities (ACT) which previous research shows capture different frames of reference. Results: Latent growth curve modeling indicated significant differences across gender and frame of reference in trajectories of change with age and in genetic and environmental contributions to change. Men have higher mean scores on all three SH measures, indicating better SH, but there were no sex differences in pattern of change with age. Accelerating declines with age were found for SRH and ACT, whereas COMP improved with age. Results indicated more genetic variance for women than men, but declining genetic variance for both after age 70. Increasing shared environmental variance with increasing age was also found for both sexes. Discussion: As aging triggers a re-evaluation of the meaning of "good health," physical aspects of health may become less important and shared cultural conceptions of health may become more relevant. This change in conceptions of good health may reflect both aging and the change in composition of the elderly population as a result of selective survival. PMID- 29590494 TI - Endocrinopathies and renal outcomes in lithium therapy: impact of lithium toxicity. AB - Background: Lithium is the mainstay of treatment for bipolar disorder, mania and an augmentation therapy in patients with treatment resistant depression. It has a narrow therapeutic index, with recognized adverse multi-system and endocrine side effects. Aim: To assess the impact of lithium therapy, in particular lithium toxicity, on the development of endocrine and renal disorders in a cohort of patients in a single tertiary referral centre in Ireland. Study design: A retrospective analysis was performed of the prevalence of lithium toxicity and renal, thyroid and parathyroid dysfunction in our study population. Methods: We collected laboratory data from the Clinical Chemistry department of the Adelaide and Meath Hospital incorporating the National Children's Hospital (AMNCH), Dublin, Ireland. Our study population included all patients who had at least one serum lithium measurement from January 1st 2000 to December 31st 2014 inclusive. Results: A total of 580 patients were included in the study. Among our study group, 70 patients (12.1%) had 1 toxic lithium measurement (lithium level >1.2 mmol/l). 27.8% (n > 161) of patients developed stage 3 Chronic kidney Disease (CKD) or higher, which was commoner in those patients who developed toxic lithium levels (P < 0.0001) and in those who developed hypernatraemia (P > 0.0001). 16.2% of patients (n > 94) had one serum sodium >145 mmol/l during follow up. 60 patients(10.3%) had a TSH >10 mU/l, while complete suppression of TSH (<0.05 mU/l) was observed in 22 patients (3.8%) during follow-up. 4% (n > 37) of the study population had >=1 serum corrected calcium level > 2.55 mmol/l, and 4 patients had biochemical confirmation of primary hyperparathyroidism but PTH levels were only performed in 2.8% (n > 16) of the studypopulation. Conclusion: Stage 3 CKD is common in patients receiving lithium therapy. Lithium toxicity is associated with CKD and hypernatraemia. Thyroid dysfunction and hypercalcaemia are common in patients receiving lithium therapy. Patients receiving lithium therapy require surveillance of renal, thyroid and bone biochemistry.

AB - High failure rates of drug candidates in the clinics, restricted-use warnings as well as withdrawals of drugs in postmarketing stages are of substantial concern for the pharmaceutical industry and drug-induced liver injury (DILI) constitutes one of the most frequent reasons for such safety failures. Importantly, as DILI cannot be accurately predicted using animal models, animal safety tests are commonly complemented with assessments in human in vitro systems. 3D spheroid cultures of primary human hepatocytes in chemically defined conditions, hereafter termed CD-spheroids, have recently emerged as a microphysiological model system in which hepatocytes retain their molecular phenotypes and hepatic functions for multiple weeks in culture. However, their predictive power for the detection of hepatotoxic liabilities has not been systematically assessed. Therefore, we here evaluated the hepatotoxicity of 123 drugs with or without direct implication in clinical DILI events. Importantly, using ATP quantifications as the single endpoint, the model accurately distinguished between hepatotoxic and nontoxic structural analogues and exceeded both sensitivity and specificity of all previously published in vitro assays at substantially lower exposure levels, successfully detecting 69% of all hepatotoxic compounds without producing any false positive results (100% specificity). Furthermore, the platform supports the culture of spheroids of primary hepatocytes from preclinical animal models, thereby allowing the identification of animal-specific toxicity events. We anticipate that CD-spheroids represent a powerful and versatile tool in drug discovery and preclinical drug development that can reliably flag hepatotoxic drug candidates and provide guidance for the selection of the most suitable animal models. PMID- 29590497 TI - Chronic idiopathic erythroderma of elderly men is an independent entity that has a distinct TARC/IgE profile from adult atopic dermatitis. AB - BACKGROUND: Although there are several diseases that cause erythroderma, patients are often encountered with erythroderma of unknown cause which persists for a long time. The aim of this study was to characterize this chronic idiopathic erythroderma (CIE). METHODS: Adult patients with CIE, atopic dermatitis (AD), psoriatic erythroderma (PsE), or generalized drug eruption (DE), who visited Fukuoka University Hospital Dermatology Department from 2010 to 2015, were enrolled. Their clinical and laboratory data were extracted from the patient database. CIE was defined as erythroderma without any apparent cause and lasting more than 3 months. RESULTS: Twenty-three CIE, 82 AD, 39 psoriatic erythroderma, and 99 drug eruption cases were enrolled. The mean age of CIE patients was 74.7 +/- 8.8, and the male : female ratio was 21 : 2. Laboratory data for CIE and AD were similar, but serum levels of thymus and activation-regulated chemokine (TARC), a T-helper (Th) 2 cytokine, in the CIE group were significantly more elevated than in the AD group. Conversely, serum immunoglobulin (Ig) E levels were significantly lower in CIE patients compared with the atopic dermatitis group, and the ROC curve of the TARC/IgE ratio (7.24) provided efficient differentiation of the CIE group from AD patients. About PsE and DE, significant elevation of C-reactive protein was observed. Aspartate aminotransferase and alanine aminotransferase were also elevated in DE. CONCLUSIONS: Chronic idiopathic erythroderma is an independent condition which is likely to occur in elderly men. Immunity is shifted to the Th2 type in CIE; however, the mechanism may differ from that of atopic dermatitis. PMID- 29590498 TI - Skin cancer risk and the use of UV nail lamps.

AB - January 2018, the American College of Obstetrics and Gynecology issued a position statement opposing the punishment of women for self-induced abortion. To those unfamiliar with emerging trends in abortion in the United States and worldwide, the need for the declaration might not be apparent. Several studies suggest that self-induced abortion is on the rise in the United States. Simultaneously, prosecutions of pregnant women for behavior thought to harm the fetus are increasing. The ACOG statement responds to both trends by urging doctors to honor the integrity and confidentiality inherent in the doctor-patient relationship. Seen in the context of the larger battle over legal abortion, the statement has far broader implications. By acknowledging the role doctors play in enforcing pregnancy-related crimes, the ACOG position statement wisely anticipates the ways in which doctors will be implicated should access to legal abortion be further restricted. To understand the need for the ACOG directive, you must first understand that the story of what will happen if abortion becomes a crime in the United States is not to be found in history books; it is staring at us across our southern border. PMID- 29590512 TI - Progress: Its Glories and Pitfalls. AB - Steven Pinker, a cognitive psychologist and linguist at Harvard and a savant of big ideas, is one of the latest to take on the idea of progress. He does it under the aegis of "enlightenment," which comes down to a kind of holy trinity of reason, science, and humanism. His new book, Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, is ambitious and cantankerous and heady with hope. On the whole, Pinker makes a good case for the benefits of progress, but with an overdose of feel-good prose. His greatest failure comes in exaggerating the threats to science and in avoiding some problems altogether. He ignores its complexity, its shadows, its creation of new problems raised by its solutions to old ones. Pinker has a particular animus against bioethics, and he misses what has been, I would argue, at the heart of bioethics from its beginning fifty or so years ago. Bioethics was prompted by a new class of medical dilemmas that require a difficult balancing of harms and benefits. Most of them are still with us, and most of them are the result of the progress of postwar medical research and fast-changing clinical practices. PMID- 29590513 TI - Genome "Surgery"? AB - When Kai Kupferschmidt writes about CRISPR-based gene editing in German, he faces an obstacle: there's no exact translation for "editing" that has the same connotations as it has in English. Instead, as he explained last fall at The Hastings Center's preconference symposium on new genetic technologies at the World Conference of Science Journalists, he draws on a variety of phrases, including "genome surgery," which conveys precision in Kupferschmidt's assessment, and "gene scissors," which communicates CRISPR's mechanistic nature. But in any language, explaining CRISPR is difficult. It's a challenge I face at The Hastings Center, where I write about biotechnology for a public audience. PMID- 29590514 TI - One Ventilator Too Few? AB - Sometimes it's better to be lucky than good. As new blood filled our young patient's veins, her breathing became regular and her pulse full. She was so far gone I would not have expected her to recover consciousness for a day, if at all, but within an hour, she began to wake up. We removed the breathing tube a couple of hours later- no ventilator ever needed. As life-sustaining technology becomes more widely available in fortunate parts of the developing world, benefits come with complications. The temptation is to focus on the thing-the ventilator itself as the crucial element and press to buy more, mistaking the problem for one of resource scarcity only. But we need a culturally relevant ethical framework to guide the use and withdrawal of ventilators and similar life-sustaining tools. Resource scarcity is only part of the problem. Buying additional ventilators only defers allocation decisions and entirely fails to address end-of-life suffering. It is unsustainable in Rwanda; it is a dubious solution anywhere. The intangible need for an ethical framework hides beneath apparent scarcity and, when this need is not addressed and luck runs out, one salvageable patient can die for want of a ventilator that serves only to prolong the suffering of another. PMID- 29590515 TI - Fetal Medicine and the Pregnant Woman. AB - In coming decades, fetal medicine may become a routine part of reproductive care. The measures pregnant women now take to protect fetal health are largely generic, like restricting their diets and using supplements. Relatively few interventions are based on specific conditions revealed by ultrasound or genetic testing. A recent finding, though, may herald a dramatic rise in "personalized" fetal medicine: certain drugs already approved by the Food and Drug Administration can apparently boost neural growth in fetuses with Down syndrome, improving cognitive functioning in the future child. Many more condition-specific findings are likely in the near future. But as commentators have frequently observed about prenatal testing, technologies that appear to increase reproductive options also complicate and constrain them. PMID- 29590516 TI - Organ Transplantation and the Uniform Anatomical Gift Act: A Fifty-Year Perspective. AB - Fifty years ago this summer, the Uniform Anatomical Gift Act was adopted by the National Conference of Commissioners on Uniform State Laws and approved by the American Bar Association. The UAGA has provided a sound and stable legal platform on which to base an effective nationwide organ donation system. The cardinal principles of altruism, autonomy, and public trust are still important. At a time when confidence and trust in our government and many private institutions has declined, maintaining trust and confidence in our health care system and its commitment to "first, do no harm" has never been more important. Any policies that override these core ethical principles could cause irreparable damage to the public's faith in our transplant system. While progress has been made to increase organ registration and the number of organs transplanted, much more must be done to realize the potential of life-saving therapy without jeopardizing ethical principles. PMID- 29590518 TI - Financial Conflicts of Interest at FDA Drug Advisory Committee Meetings. AB - The U.S. Food and Drug Administration's drug advisory committees provide expert assessments of the safety and efficacy of new therapies considered for approval. A committee hears from a variety of speakers, from six groups, including voting members of the committee, FDA staff members, employees of the pharmaceutical company seeking approval of a therapy, patient and consumer representatives, expert speakers invited by the company, and public participants. The committees convene at the request of the FDA when the risks and harms of novel products are not immediately clear, and their final decisions carry significant weight, as most therapies that receive advisory committee approval are subsequently approved by the FDA. In recent years, across a series of diverse publications, the financial conflicts of interest of each category of participants in the meetings have been investigated. Here, we summarize these findings and their ethical implications, focusing on the FDA Oncologic Drugs Advisory Committee, and we suggest ways to move toward more transparent and impartial advisory committee meetings. PMID- 29590519 TI - Nudge or Grudge? Choice Architecture and Parental Decision-Making. AB - Richard Thaler and Cass Sunstein define a nudge as "any aspect of the choice architecture that alters people's behavior in a predictable way without forbidding any options or significantly changing their economic incentives." Much has been written about the ethics of nudging competent adult patients. Less has been written about the ethics of nudging surrogates' decision-making and how the ethical considerations and arguments in that context might differ. Even less has been written about nudging surrogate decision-making in the context of pediatrics, despite fundamental differences that exist between the pediatric and adult contexts. Yet, as the field of behavioral economics matures and its insights become more established and well-known, nudges will become more crafted, sophisticated, intentional, and targeted. Thus, the time is now for reflection and ethical analysis regarding the appropriateness of nudges in pediatrics. We argue that there is an even stronger ethical justification for nudging in parental decision-making than with competent adult patients deciding for themselves. We give three main reasons in support of this: (1) child patients do not have autonomy that can be violated (a concern with some nudges), and nudging need not violate parental decision-making authority; (2) nudging can help fulfill pediatric clinicians' obligations to ensure parental decisions are in the child's interests, particularly in contexts where there is high certainty that a recommended intervention is low risk and of high benefit; and (3) nudging can relieve parents' decisional burden regarding what is best for their child, particularly with decisions that have implications for public health. PMID- 29590520 TI - Mass Shootings, Mental Illness, and Gun Control. AB - In the wake of the Stoneman Douglas School shooting, Republican and Democratic leaders-like the American electorate they represent-remain sharply divided in their responses to gun violence. They are united in their condemnation of these mass shootings, but they disagree about whether stricter or looser gun control laws are the answer. Those on the right side of the political aisle suggest that the issue is one of mental illness rather than gun control. Conversely, those who are more liberal or progressive in their political learnings are quick to condemn attempts to reframe the issue of mass shootings as a mental health problem. Both sides are wrong. Mass shootings are indeed partially a mental health problem, albeit one poorly addressed by our current laws and policies. But the solution to mass shootings also needs to consider strategies that may reduce gun violence in general. PMID- 29590521 TI - The Right to Know: A Revised Standard for Reporting Incidental Findings. AB - During the course of biomedical research, researchers sometimes obtain information on participants that is outside the aim of the study but may nonetheless be relevant to the participants. These incidental findings, as they are known, have been the focus of a substantial amount of discussion in the bioethics literature, and a consensus has begun to emerge about what researchers should do in light of the possibility of incidental findings. A consensus, however, is not necessarily correct. In this article, we address the common view that reporting of incidental findings should be based primarily on the possibility of medical benefit, factoring in the findings' validity, clinical actionability, and significance to health or reproduction. While such medical beneficence should not be discarded, the need to give proper attention to participants' autonomy, privacy, and interests (especially considering discussion of participants' right not to know) suggests an alternative standard for when to report incidental findings: even if they are of no direct medical benefit, incidental findings should be reported based on the extent to which the participant can be expected to comprehend the information. We will offer a preliminary defense of this alternative as best respecting participants' autonomy and privacy and promoting their interests. However, we acknowledge that the standard would face significant practical barriers, and these barriers lead us to propose a metaconsent addendum that would allow subjects to essentially waive the comprehension standard when resource or other constraints make meeting it impracticable. PMID- 29590522 TI - Bioethics and Science. AB - Bioethics comes in for furious criticism in Stephen Pinker's new book, Enlightenment Now. Pinker argues that scientists are making human lives better and better, and that lives would get still better even faster if bioethicists did not use ideas like informed consent, dignity, sacredness, and social justice to hobble the scientists. Daniel Callahan, a cofounder of The Hastings Center and arguably of bioethics, is perhaps the best living embodiment of a bioethicist who has written about medical progress, and the March-April 2018 issue of the Hastings Center Report turns to him for a review of Pinker's book. In his essay, Callahan describes bioethics as guiding science, addressing problems generated by scientific developments and attempting to head off possible problems, rather than as broadly opposing science. That description of bioethics serves as well as anything to convey the flavor of much of this issue of the Report. PMID- 29590523 TI - Long-term follow-up comparison of two different bi-layer dermal substitutes in tissue regeneration: Clinical outcomes and histological findings. AB - Double layer dermal substitute (DS) consist of a 3-dimensional collagen structures and a superficial silicon layer that are positioned within the defect provide to promote tissue regeneration in skin wounds. DS often have unique physical characteristics due to differences in manufacturing techniques. The aim of this study is the clinical and histological comparison of Nevelia and Integra double layer DSs in patients with post-traumatic injury wounds. Thirty patients with post-traumatic wounds localised on the inferior limbs were randomised in 2 groups Nevelia or Integra, followed by autologous dermal epidermal graft (DEG). Clinical results were evaluated through the healing time; Manchester Scar Scale (MSS) and Visual Analog Scale (VAS) at 1, 2, and 3 weeks and after 1 and 3 years. Histological and immunohistochemical evaluation were performed at 0, 2, and 3 weeks. The difference in healing time between groups (P = .467, log-rank test), pain and self-estimation was not statistically significant after 35, 42, and 49 days and at 1-year follow up. Histological data showed evident healing of wound after 2 weeks compared with preoperative with both DSs. At 3 weeks reepithelialisation and dermal regeneration were evident with both substitutes; however Nevelia showed early regenerative properties in terms of epidermal proliferation and dermal renewal compared with Integra. Nevelia showed also a more evident angiogenesis vs Integra evaluated as alpha-SMA immunohistochemistry. Differences in the MSS score were statistically significant at 3 years follow up in favour of Nevelia group (P = .001). At long-term follow up, Nevelia showed a better clinical outcome measured as MSS score vs Integra measured as MSS. Histological and immunohistochemistry data showed that Nevelia allows faster neoangiogenesis and tissue regeneration with neoformed tissue architecture closer to the physiology of the skin. PMID- 29590524 TI - [Neuroimaging studies of depression: Current status and future direction.] AB - Recent advances in neuroimaging studies enable us to measure brain function non invasively. Over the past several decades, neuroimaging measurement has been substantially applied to elucidate the neurobiological mechanisms underlying major depressive disorder (MDD). Since MDD is a wide spectrum which consists of various symptoms such as low mood or loss of interest and is considered to affect a biologically het- erogeneous population, we have not yet elucidated the biological underpinnings of MDD. It seems to be more promising to consider MDD as an integral network abnormality instead of deficits in specific brain regions or neurotransmitters. We firstly provide a comprehensive review of the extant neuroimaging literature including structural and functional magnetic resonance imaging, magnetic resonance spectroscopy, single pho- ton emission computed tomography, and positron emission tomography studies. Then we show our neuroimaging studies for MDD toward po- tential application as a biomarker for diagnosis and treatment. We believe it will facilitate the development, of a more integrative model of neural dysfunction in MDD.

AB - The present work demonstrates the formation of self-aligned nanoporous architecture of gallium oxide by anodization of gallium metal film controlled at 15 degrees C in aqueous electrolyte consisting of phosphoric acid. SEM examination of the anodized film reveals that by adding ethylene glycol to the electrolyte and optimizing the ratio of phosphoric acid and water, chemical etching at the oxide/electrolyte interfaces can be controlled, leading to the formation of aligned nanotubular oxide structures with closed bottom. XPS analysis confirms the chemical composition of the oxide film as Ga2O3. Further, XRD and SAED examination reveals that the as-synthesized nanotubular structure is amorphous, and can be crystallized to beta-Ga2O3 phase by annealing the film at 600 degrees C. The nanotubular structured film, when used as photoanode for photoelectrochemical splitting of water, achieved a higher photocurrent of about two folds than that of the nanoporous film, demonstrating the rewarding effect of the nanotubular structure. In addition, the work also demonstrates the formation of highly organized nonporous Ga2O3 structure on a nonconducting glass substrate coated with thin film of Ga-metal, highlighting that the current approach can be extended for the formation of self-organized nanoporous Ga2O3 thin film even on nonconducting flexible substrates. PMID- 29590526 TI - Hydrogen-Bonding-Driven 3D Supramolecular Assembly of Peptidomimetic Zipper. AB - Hydrogen-bonding-driven three-dimensional (3D) assembly of a peptidomimetic zipper has been established for the first time by using an alpha/AApeptide zipper that assembles into a de novo lattice arrangement through two layers of hydrogen bonded linker-directed interactions. Via a covalently bridged 1D 413-helix, drastic enhancement in stability has been achieved in the formed 3D crystalline supramolecular architecture as evidenced by gas-sorption studies. As the first example of an unnatural peptidic zipper, the dimensional augmentation of the zipper differs from metal-coordinated strategies, and may have general implications for the preparation of peptidic functional materials for a variety of future applications. PMID- 29590527 TI - Dual-Readout Immunochromatographic Assay by Utilizing MnO2 Nanoflowers as the Unique Colorimetric/Chemiluminescent Probe. AB - Manganese dioxide nanoflowers (MnO2 NFs) were synthesized and used as a dual readout probe to develop a novel immunochromatographic test strip (ITS) for detecting pesticide residues using chlorpyrifos as the model analyte. MnO2 NFs labeled antibody for chlorpyrifos was employed as the signal tracer for conducting the ITS. After 10 min competitive immunoreaction, the tracer antibody was captured by the immobilized immunogen in the test strip, resulting in the captured MnO2 NFs on test line. The captured MnO2 NFs led to the appearance of brown color on the test line, which could be easily observed by the naked eye as a qualitative readout. Due to the very slight colorimetric difference of chlorpyrifos at trace concentrations, the semiquantitative readout by naked eyes could not meet the demand of quantitative analysis. MnO2 NFs showed a significant effect on the luminol-H2O2 chemiluminescent (CL) system, and the CL signal driven by MnO2 NFs were used to detect the trace concentration of chlorpyrifos quantitatively. 1,3-Diphenylisobenzofuran quenching studies and TMB-H2O2 coloration assays were conducted for studying the enhancing mechanism of MnO2 NFs, which was based on the oxidant activity to decompose H2O2 for forming reactive oxygen species. Under optimal conditions, the linear range of chlorpyrifos was 0.1-50 ng/mL with a low detection limit of 0.033 ng/mL (S/N = 3). The reliability of the dual-readout ITS was successfully demonstrated by the application on traditional Chinese medicine and environmental water samples. Due to the simultaneous rapid-qualitative and sensitive-quantitative detection, the dual-readout protocol provides a promising strategy for rapid screening and field assay on various areas such as environmental monitoring and food safety. PMID- 29590528 TI - Interaction of the H-Cluster of FeFe Hydrogenase with Halides. AB - FeFe hydrogenases catalyze H2 oxidation and production using an "H-cluster", where two Fe ions are bound by an aza-dithiolate (adt) ligand. Various hypotheses have been proposed (by us and others) to explain that the enzyme reversibly inactivates under oxidizing, anaerobic conditions: intramolecular binding of the N atom of adt, formation of the so-called "Hox/inact" state or nonproductive binding of H2 to isomers of the H-cluster. Here, we show that none of the above explains the new finding that the anaerobic, oxidative, H2-dependent reversible inactivation is strictly dependent on the presence of Cl- or Br-. We provide experimental evidence that chloride uncompetitively inhibits the enzyme: it reversibly binds to catalytic intermediates of H2 oxidation (but not to the resting "Hox" state), after which oxidation locks the active site into a stable, saturated, inactive form, the structure of which is proposed here based on DFT calculations. The halides interact with the amine group of the H-cluster but do not directly bind to iron. It should be possible to stabilize the inhibited state in amounts compatible with spectroscopic investigations to explore further this unexpected reactivity of the H-cluster of hydrogenase. PMID- 29590529 TI - Measurement of Tau Filament Fragmentation Provides Insights into Prion-like Spreading. AB - The ordered assembly of amyloidogenic proteins causes a wide spectrum of common neurodegenerative diseases, including Alzheimer's and Parkinson's diseases. These diseases share common features with prion diseases, in which misfolded proteins can self-replicate and transmit disease across different hosts. Deciphering the molecular mechanisms that underlie the amplification of aggregates is fundamental for understanding how pathological deposits can spread through the brain and drive disease. Here, we used single-molecule microscopy to study the assembly and replication of tau at the single aggregate level. We found that tau aggregates have an intrinsic ability to amplify by filament fragmentation, and determined the doubling times for this replication process by kinetic modeling. We then simulated the spreading time for aggregates through the brain and found this to be in good agreement with both the observed time frame for spreading of pathological tau deposits in Alzheimer's disease and in experimental models of tauopathies. With this work we begin to understand the physical parameters that govern the spreading rates of tau and other amyloids through the human brain.

AB - The emerging metasurfaces with the exceptional capability of manipulating an arbitrary wavefront have revived the holography with unprecedented prospects. However, most of the reported metaholograms suffer from limited polarization controls for a restrained bandwidth in addition to their complicated meta-atom designs with spatially variant dimensions. Here, we demonstrate a new concept of vectorial holography based on diatomic metasurfaces consisting of metamolecules formed by two orthogonal meta-atoms. On the basis of a simply linear relationship between phase and polarization modulations with displacements and orientations of identical meta-atoms, active diffraction of multiple polarization states and reconstruction of holographic images are simultaneously achieved, which is robust against both incident angles and wavelengths. Leveraging this appealing feature, broadband vectorial holographic images with spatially varying polarization states and dual-way polarization switching functionalities have been demonstrated, suggesting a new route to achromatic diffractive elements, polarization optics, and ultrasecure anticounterfeiting.

PMID- 29590533 TI - Three Unresolved Issues in Human Morality. AB - This article discusses three major, but related, controversies surrounding the idea of morality. Is the complete pattern of features defining human morality unique to this species? How context dependent are moral beliefs and the emotions that often follow a violation of a moral standard? What developmental sequence establishes a moral code? This essay suggests that human morality rests on a combination of cognitive and emotional processes that are missing from the repertoires of other species. Second, the moral evaluation of every behavior, whether by self or others, depends on the agent, the action, the target of the behavior, and the context. The ontogeny of morality, which begins with processes that apes possess but adds language, inference, shame, and guilt, implies that humans are capable of experiencing blends of thoughts and feelings for which no semantic term exists. As a result, conclusions about a person's moral emotions based only on questionnaires or interviews are limited to this evidence. PMID- 29590534 TI - The role of IL-6 in exercise-induced anorexia in normal-weight boys. AB - Our previous study showed that interleukin-6 (IL-6) is associated with suppression of appetite after high-intensity exercise (HIEX), but an independent role in food intake (FI) was not defined. We hypothesized that IL-6 suppresses appetite and FI, independently of appetite hormones, after HIEX in normal-weight (NW) boys. We investigated the effect of HIEX, with and without the inflammation inhibitor ibuprofen (IBU), on IL-6, other biomarkers of inflammation and appetite, FI, and ratings of appetite in NW boys. Fifteen NW boys (aged 13-18 years) were randomly assigned in a crossover design to 4 sessions: (i) water and rest, (ii) IBU and rest, (iii) water and HIEX, and (iv) IBU and HIEX. HIEX consisted of three 10-min bouts of exercise at 75% of maximal oxygen uptake with 90 s of active rest between bouts. IBU (300 mg) was given as a liquid suspension. FI, ratings of appetite, and plasma biomarkers of appetite, inflammation, stress, and glucose control were measured. FI was not affected by HIEX or IBU. Appetite increased over time (p = 0.002) but was lower after HIEX (p < 0.001) and not affected by IBU. HIEX, but not IBU, resulted in higher levels of IL-6 (p < 0.001) and cortisol (p < 0.001) and lower active ghrelin (p < 0.001). IL-6 correlated with active ghrelin (r = 0.37; p = 0.036) and cortisol (r = 0.26; p = 0.049). An independent role for IL-6 in appetite suppression was not supported. However, IL 6 was correlated with active ghrelin and cortisol, thus potentially mediating appetite via these interactions.

Non-small cell lung cancer (NSCLC) accounts for 80%-85% of total lung cancer cases. Dachshund homolog 1 (DACH1), is a protein encoded by the DACH1 gene in humans. DACH1 inhibits lung adenocarcinoma invasion and tumor growth but has a lower expression in NSCLC. To investigate the mechanisms of decreased DACH1 expression, its DNA methylation patterns were investigated. The results showed a higher methylation rate in NSCLC compared with the adjacent normal lung tissues. Cell transfection experiments showed that increased methylation impaired transcription factor transactivation. In vivo demethylation treatment and overexpression of DACH1 increased apoptosis and decreased migration and invasion in NSCLC A549 cells. Our research provides new insight into NSCLC pathogenesis and identifies a new therapeutic target.

AB - The mechanistic target of rapamycin complex-1 (mTORC-1) is a key nutrient and contraction-sensitive protein that regulates a pathway leading to skeletal muscle growth. Utilizing a multiplex assay, we aimed to examine the phosphorylation status of key mTORC-1-related signalling molecules in response to protein feeding and resistance exercise. Eight healthy men (age, 22.5 +/- 3.1 years; mass, 80 +/- 9 kg; 1-repetition maximum leg extension, 87 +/- 5 kg) performed 4 sets of unilateral leg extensions until volitional failure. Immediately following the final set, all participants consumed a protein-enriched beverage. A single skeletal muscle biopsy was obtained from the vastus lateralis before (Pre) with further bilateral biopsies at 1 h (1 h exercised legs (FEDEX) and 1 h nonexercised legs (FED)) and 3 h (3 h FEDEX and 3 h FED) after drink ingestion. Phosphorylated AktSer473 was significantly elevated from Pre at 1 h FEDEX. Phosphorylated p70S6K1Thr412 was significantly increased above Pre at 1 h FEDEX and 1 h FED and was still significantly elevated at 3 h FEDEX but not 3 h FED. Phosphorylated rpS6Ser235/236 was also significantly increased above Pre at 1 h FEDEX and 1 h FED with 1 h FEDEX greater than 1 h FED. Our data highlight the utility of a multiplex assay to assess anabolic signalling molecules in response to protein feeding and resistance exercise in humans. Importantly, these changes are comparable with those as previously reported using standard immunoblotting and protein activity assays.

AB - BACKGROUND: Since 2004, a regimen of 6 months of treatment with oxaliplatin plus a fluoropyrimidine has been standard adjuvant therapy in patients with stage III colon cancer. However, since oxaliplatin is associated with cumulative neurotoxicity, a shorter duration of therapy could spare toxic effects and health expenditures. METHODS: We performed a prospective, preplanned, pooled analysis of six randomized, phase 3 trials that were conducted concurrently to evaluate the noninferiority of adjuvant therapy with either FOLFOX (fluorouracil, leucovorin, and oxaliplatin) or CAPOX (capecitabine and oxaliplatin) administered for 3 months, as compared with 6 months. The primary end point was the rate of disease free survival at 3 years. Noninferiority of 3 months versus 6 months of therapy could be claimed if the upper limit of the two-sided 95% confidence interval of the hazard ratio did not exceed 1.12. RESULTS: After 3263 events of disease recurrence or death had been reported in 12,834 patients, the noninferiority of 3 months of treatment versus 6 months was not confirmed in the overall study population (hazard ratio, 1.07; 95% confidence interval [CI], 1.00 to 1.15). Noninferiority of the shorter regimen was seen for CAPOX (hazard ratio, 0.95; 95% CI, 0.85 to 1.06) but not for FOLFOX (hazard ratio, 1.16; 95% CI, 1.06 to 1.26). In an exploratory analysis of the combined regimens, among the patients with T1, T2, or T3 and N1 cancers, 3 months of therapy was noninferior to 6 months, with a 3-year rate of disease-free survival of 83.1% and 83.3%, respectively (hazard ratio, 1.01; 95% CI, 0.90 to 1.12). Among patients with cancers that were classified as T4, N2, or both, the disease-free survival rate for a 6-month duration of therapy was superior to that for a 3-month duration (64.4% vs. 62.7%) for the combined treatments (hazard ratio, 1.12; 95% CI, 1.03 to 1.23; P=0.01 for superiority). CONCLUSIONS: Among patients with stage III colon cancer receiving adjuvant therapy with FOLFOX or CAPOX, noninferiority of 3 months of therapy, as compared with 6 months, was not confirmed in the overall population. However, in patients treated with CAPOX, 3 months of therapy was as effective as 6 months, particularly in the lower-risk subgroup. (Funded by the National Cancer Institute and others.). PMID- 29590548 TI - The Verge of Collapse. PMID- 29590547 TI - Ibrutinib plus Venetoclax for the Treatment of Mantle-Cell Lymphoma. AB - BACKGROUND: Both the BTK inhibitor ibrutinib and the BCL2 inhibitor venetoclax are active as monotherapy in the treatment of mantle-cell lymphoma. Complete response rates of 21% have been observed for each agent when administered as long term continuous therapy. Preclinical models predict synergy in combination. METHODS: We conducted a single-group, phase 2 study of daily oral ibrutinib and venetoclax in patients, as compared with historical controls. Patients commenced ibrutinib monotherapy at a dose of 560 mg per day. After 4 weeks, venetoclax was added in stepwise, weekly increasing doses to 400 mg per day. Both drugs were continued until progression or an unacceptable level of adverse events. The primary end point was the rate of complete response at week 16. Minimal residual disease (MRD) was assessed by flow cytometry in bone marrow and by allele specific oligonucleotide-polymerase chain reaction (ASO-PCR) in blood. RESULTS: The study included 24 patients with relapsed or refractory mantle-cell lymphoma (23 patients) or previously untreated mantle-cell lymphoma (1 patient). Patients were 47 to 81 years of age, and the number of previous treatments ranged from none to six. Half the patients had aberrations of TP53, and 75% had a high-risk prognostic score. The complete response rate according to computed tomography at week 16 was 42%, which was higher than the historical result of 9% at this time point with ibrutinib monotherapy (P<0.001). The rate of complete response as assessed by positron-emission tomography was 62% at week 16 and 71% overall. MRD clearance was confirmed by flow cytometry in 67% of the patients and by ASO-PCR in 38%. In a time-to-event analysis, 78% of the patients with a response were estimated to have an ongoing response at 15 months. The tumor lysis syndrome occurred in 2 patients. Common side effects were generally low grade and included diarrhea (in 83% of the patients), fatigue (in 75%), and nausea or vomiting (in 71%). CONCLUSIONS: In this study involving historical controls, dual targeting of BTK and BCL2 with ibrutinib and venetoclax was consistent with improved outcomes in patients with mantle-cell lymphoma who had been predicted to have poor outcomes with current therapy.

AB - Products of the proopiomelanocortin (POMC) prohormone regulate aspects of analgesia, reward, and energy balance; thus, the neurons that produce POMC in the hypothalamus have received considerable attention. However, there are also cells in the nucleus of the solitary tract (NTS) that transcribe Pomc, although low levels of Pomc mRNA and relative lack of POMC peptide products in the adult mouse NTS have hindered the study of these cells. Therefore, studies of NTS POMC cells have largely relied on transgenic mouse lines. Here, we set out to determine the amino acid (AA) transmitter phenotype of NTS POMC neurons by using Pomc-Gfp transgenic mice to identify POMC cells. We found that cells expressing the green fluorescent protein (GFP) represent a mix of GABAergic and glutamatergic cells as indicated by Gad2 and vesicular Glut2 ( vGlut2) mRNA expression, respectively. We then examined the AA phenotype of POMC cells labeled by a Pomc-Cre transgene and found that these are also a mix of GABAergic and glutamatergic cells. However, the NTS cells labeled by the Gfp- and Cre-containing transgenes represented distinct populations of cells in three different Pomc-Cre mouse lines. Consistent with previous work, we were unable to reliably detect Pomc mRNA in the NTS despite clear expression in the hypothalamus. Thus, it was not possible to determine which transgenic tool most accurately identifies NTS cells that may express Pomc or release POMC peptides, although the results indicate the transgenic tools for study of these NTS neurons can label disparate populations of cells with varied AA phenotypes.

AB - The hormone ghrelin promotes eating and is widely considered to be a hunger signal. Ghrelin receptors, growth hormone secretagogue receptors (GHSRs), are found in a number of specific regions throughout the brain, including the lateral septum (LS), an area not traditionally associated with the control of feeding. Here we investigated whether GHSRs in the LS play a role in the control of food intake. We examined the feeding effects of ghrelin and the GHSR antagonists ([d Lys3]-growth hormone-releasing peptide-6 and JMV-2959) at doses subthreshold for effect when delivered to the lateral ventricle. Intra-LS ghrelin significantly increased chow intake during the midlight phase, suggesting that pharmacological activation of LS GHSRs promotes feeding. Conversely, GHSR antagonist delivered to the LS shortly before dark onset significantly reduced chow intake. These data support the hypothesis that exogenous and endogenous stimulation of GHSRs in the LS influence feeding. Ghrelin is known to affect motivation for food, and the dorsal subdivision of LS (dLS) has been shown to play a role in motivation. Thus, we investigated the role of dLS GHSRs in motivation for food reward by examining operant responding for sucrose on a progressive ratio (PR) schedule. Intra-dLS ghrelin increased PR responding for sucrose, whereas blockade of LS GHSRs did not affect responding in either a fed or fasted state. Together these findings for the first time substantiate the LS as a site of action for ghrelin signaling in the control of food intake.

AB - The sympathetic nerve activity (SNA) to brown adipose tissue (BAT) regulates BAT thermogenesis to defend body temperature in cold environments or to produce fever during immune responses. The vagus nerve contains afferents that inhibit the BAT SNA and BAT thermogenesis evoked by skin cooling. We sought to determine whether activation of transient receptor potential vanilloid 1 (TRPV1) channels in the nucleus tractus solitarius (NTS), which are prominently expressed in unmyelinated vagal afferents, would affect cold-evoked BAT thermogenesis, cardiovascular parameters, or their vagal afferent-evoked responses. In urethane-chloralose anesthetized rats, during skin cooling, nanoinjection of the TRPV1-agonist resiniferatoxin in NTS decreased BAT SNA (from 695 +/- 195% of baseline during cooling to 103 +/- 8% of baseline after resiniferatoxin), BAT temperature (-0.8 +/- 0.1 degrees C), expired CO2 (-0.3 +/- 0.04%), mean arterial pressure (MAP; 20 +/- 5 mmHg), and heart rate (-44 +/- 11 beats/min). Pretreatment of NTS with the TRPV1 antagonist capsazepine prevented these resiniferatoxin-mediated effects. Intravenous injection of the TRPV1 agonist dihydrocapsaicin also decreased all the measured variables (except MAP). Bilateral cervical or subdiaphragmatic vagotomy attenuated the decreases in BAT SNA and thermogenesis evoked by nanoinjection of resiniferatoxin in NTS but did not prevent the decreases in BAT SNA and BAT thermogenesis evoked by intravenous dihydrocapsaicin. We conclude that activation of TRPV1 channels in the NTS of vagus nerve intact rats inhibits BAT SNA and decreases BAT metabolism, blood pressure, and heart rate. In contrast, the inhibition of BAT thermogenesis following systemic administration of dihydrocapsaicin does not require vagal afferent activity, consistent with a nonvagal pathway through which systemic TRPV1 agonists can inhibit BAT thermogenesis.

AB - Sickle cell disease (SCD) is a genetic disorder associated with hemolytic anemia, end-organ damage, reduced survival, and pain. One of the unique features of SCD is recurrent and unpredictable episodes of acute pain due to vasoocclusive crisis requiring hospitalization. Additionally, patients with SCD often develop chronic persistent pain. Currently, sickle cell pain is treated with opioids, an approach limited by adverse effects. Because pain can start at infancy and continue throughout life, preventing the genesis of pain may be relatively better than treating the pain once it has been evoked. Therefore, we provide insights into the cellular and molecular mechanisms of sickle cell pain that contribute to the activation of the somatosensory system in the peripheral and central nervous systems. These mechanisms include mast cell activation and neurogenic inflammation, peripheral nociceptor sensitization, maladaptation of spinal signals, central sensitization, and modulation of neural circuits in the brain. In this review, we describe potential preventive/therapeutic targets and their targeting with novel pharmacologic and/or integrative approaches to ameliorate sickle cell pain.

PMID- 29590557 TI - Response of catecholaminergic neurons in the mouse hindbrain to glucoprivic stimuli is astrocyte dependent. AB - Hindbrain catecholaminergic (CA) neurons are required for critical autonomic, endocrine, and behavioral counterregulatory responses (CRRs) to hypoglycemia. Recent studies suggest that CRR initiation depends on hindbrain astrocyte glucose sensors (McDougal DH, Hermann GE, Rogers RC. Front Neurosci 7: 249, 2013; Rogers RC, Ritter S, Hermann GE. Am J Physiol Regul Integr Comp Physiol 310: R1102 R1108, 2016). To test the proposition that hindbrain CA responses to glucoprivation are astrocyte dependent, we utilized transgenic mice in which the calcium reporter construct (GCaMP5) was expressed selectively in tyrosine hydroxylase neurons (TH-GCaMP5). We conducted live cell calcium-imaging studies on tissue slices containing the nucleus of the solitary tract (NST) or the ventrolateral medulla, critical CRR initiation sites. Results show that TH-GCaMP5 neurons are robustly activated by a glucoprivic challenge and that this response is dependent on functional astrocytes. Pretreatment of hindbrain slices with fluorocitrate (an astrocytic metabolic suppressor) abolished TH-GCaMP5 neuronal responses to glucoprivation, but not to glutamate. Pharmacologic results suggest that the astrocytic connection with hindbrain CA neurons is purinergic via P2 receptors. Parallel imaging studies on hindbrain slices of NST from wild-type C57BL/6J mice, in which astrocytes and neurons were prelabeled with a calcium reporter dye and an astrocytic vital dye, show that both cell types are activated by glucoprivation but astrocytes responded significantly sooner than neurons. Pretreatment of these hindbrain slices with P2 antagonists abolished neuronal responses to glucoprivation without interruption of astrocyte responses; pretreatment with fluorocitrate eliminated both astrocytic and neuronal responses. These results support earlier work suggesting that the primary detection of glucoprivic signals by the hindbrain is mediated by astrocytes. PMID- 29590559 TI - Decreased prefrontal oxygenation elicited by stimulation of limb mechanosensitive afferents during cycling exercise. AB - Our laboratory reported using near-infrared spectroscopy that feedback from limb mechanoafferents may decrease prefrontal oxygenated-hemoglobin concentration (Oxy Hb) during the late period of voluntary and passive cycling. To test the hypothesis that the decreased Oxy-Hb of the prefrontal cortex would be augmented depending on the extent of limb mechanoafferent input, the prefrontal Oxy-Hb response was measured during motor-driven one- and two-legged passive cycling for 1 min at various revolutions of pedal movement in 19 subjects. Furthermore, we examined whether calculated tissue oxygenation index (TOI) decreased during passive cycling as the Oxy-Hb did, simultaneously assessing blood flows of extracranial cutaneous tissue and the common and internal carotid arteries (CCA and ICA) with laser and ultrasound Doppler flowmetry. Minute ventilation and cardiac output increased and peripheral resistance decreased during passive cycling, depending on both revolutions of pedal movement and number of limbs, whereas mean arterial blood pressure did not change. Passive cycling did not change end-tidal CO2, suggesting absence of a hypocapnic change. Prefrontal Oxy Hb decreased during passive cycling, being in proportion to revolution of pedal movement but not number of cycling limbs. In addition, prefrontal TOI decreased during passive cycling as Oxy-Hb did, whereas blood flows of forehead cutaneous tissue, CCA, and ICA did not change significantly. Thus, a decrease in Oxy-Hb reflected a decrease in tissue blood flow of the intracerebral vasculature but not the extracerebral compartment. It is likely that feedback from mechanoafferents decreased regional cerebral blood flow of the prefrontal cortex in relation to the revolutions of pedal movement. PMID- 29590558 TI - Insulin increases ventilation during euglycemia in humans. AB - Evidence from animal studies indicates that hyperinsulinemia, without changes in glucose, increases ventilation via a carotid body-mediated mechanism. However, whether insulin elevates ventilation in humans independently of changes in glucose remains unclear. Therefore, we tested the hypothesis that insulin increases ventilation in humans during a hyperinsulinemic-euglycemic clamp in which insulin was elevated to postprandial concentrations while glucose was maintained at fasting concentrations. First, in 16 healthy young men ( protocol 1), we retrospectively analyzed respiration rate and estimated tidal volume from a pneumobelt to calculate minute ventilation during a hyperinsulinemic-euglycemic clamp. In addition, for a direct assessment of minute ventilation during a hyperinsulinemic-euglycemic clamp, we retrospectively analyzed breath-by-breath respiration rate and tidal volume from inspired/expired gasses in an additional 23 healthy young subjects ( protocol 2). Clamp infusion elevated minute ventilation from baseline in both protocols ( protocol 1: +11.9 +/- 4.6% baseline, P = 0.001; protocol 2: +9.5 +/- 3.8% baseline, P = 0.020). In protocol 1, peak changes in both respiration rate (+13.9 +/- 3.0% baseline, P < 0.001) and estimated tidal volume (+16.9 +/- 4.1% baseline, P = 0.001) were higher than baseline during the clamp. In protocol 2, tidal volume primarily increased during the clamp (+9.7 +/- 3.7% baseline, P = 0.016), as respiration rate did not change significantly (+0.2 +/- 1.8% baseline, P = 0.889). Collectively, we demonstrate for the first time in humans that elevated plasma insulin increases minute ventilation independent of changes in glucose.

AB - Living cells orient the cytoskeleton polarity and directional migration in response to spatial gradients of multiple types of cues. The resulting tactic behaviors are critical for the proper cell localization in the context of complex single-cell and tissue behaviors. In this perspective, we highlight the recent discovery of, to our knowledge, a new -taxis phenomenon, the topotaxis, which mediates directional cell migration in response to the gradients of such topographic features as the density of extracellular matrix fibers. The direction of topotactic migration critically depends on the effective stiffness of the cortical cytoskeleton, which is controlled by the balance between two parallel signaling pathways activated by the extracellular matrix input. Topotaxis can account for such striking cell behaviors as the opposite directionality of migration of benign and metastatic cancer cells and certain aspects of the wound healing process. We anticipate that, in conjunction with other tactic phenomena, topotaxis can provide critical information for understanding and design of tissue structure and function. PMID- 29590583 TI - Fodis: Software for Protein Unfolding Analysis. AB - The folding dynamics of proteins at the single-molecule level has been studied with single-molecule force spectroscopy experiments for 20 years, but a common standardized method for the analysis of the collected data and for sharing among the scientific community members is still not available. We have developed a new open-source tool-Fodis-for the analysis of the force-distance curves obtained in single-molecule force spectroscopy experiments, providing almost automatic processing, analysis, and classification of the obtained data. Our method provides also a classification of the possible unfolding pathways and the structural heterogeneity present during the unfolding of proteins. PMID- 29590584 TI - CONAN: A Tool to Decode Dynamical Information from Molecular Interaction Maps. AB - The analysis of contacts is a powerful tool to understand biomolecular function in a series of contexts, from the investigation of dynamical behavior at equilibrium to the study of nonequilibrium dynamics in which the system moves between multiple states. We thus propose a tool called CONtact ANalysis (CONAN) that, from molecular dynamics (MD) trajectories, analyzes interresidue contacts, creates videos of time-resolved contact maps, and performs correlation, principal component, and cluster analysis, revealing how specific contacts relate to functionally relevant states sampled by MD. We present how CONAN can identify features describing the dynamics of ubiquitin both at equilibrium and during mechanical unfolding. Additionally, we show the analysis of MD trajectories of an alpha-synuclein mutant peptide that undergoes an alpha-beta conformational transition that can be easily monitored using CONAN, which identifies the multiple states that the peptide explores along its conformational dynamics. The high versatility and ease of use of the software make CONAN a tool that can significantly facilitate the understanding of the complex dynamical behavior of proteins or other biomolecules. CONAN and its documentation are freely available for download on GitHub. PMID- 29590586 TI - Human Blue Cone Opsin Regeneration Involves Secondary Retinal Binding with Analog Specificity. AB - Human color vision is mediated by the red, green, and blue cone visual pigments. Cone opsins are G-protein-coupled receptors consisting of an opsin apoprotein covalently linked to the 11-cis-retinal chromophore. All visual pigments share a common evolutionary origin, and red and green cone opsins exhibit a higher homology, whereas blue cone opsin shows more resemblance to the dim light receptor rhodopsin. Here we show that chromophore regeneration in photoactivated blue cone opsin exhibits intermediate transient conformations and a secondary retinoid binding event with slower binding kinetics. We also detected a fine tuning of the conformational change in the photoactivated blue cone opsin binding site that alters the retinal isomer binding specificity. Furthermore, the molecular models of active and inactive blue cone opsins show specific molecular interactions in the retinal binding site that are not present in other opsins. These findings highlight the differential conformational versatility of human cone opsin pigments in the chromophore regeneration process, particularly compared to rhodopsin, and point to relevant functional, unexpected roles other than spectral tuning for the cone visual pigments. PMID- 29590585 TI - Hexahydrated Mg2+ Binding and Outer-Shell Dehydration on RNA Surface. AB - The interaction between metal ions, especially Mg2+ ions, and RNA plays a critical role in RNA folding. Upon binding to RNA, a metal ion that is fully hydrated in bulk solvent can become dehydrated. Here we use molecular dynamics simulation to investigate the dehydration of bound hexahydrated Mg2+ ions. We find that a hydrated Mg2+ ion in the RNA groove region can involve significant dehydration in the outer hydration shell. The first or innermost hydration shell of the Mg2+ ion, however, is retained during the simulation because of the strong ion-water electrostatic attraction. As a result, water-mediated hydrogen bonding remains an important form for Mg2+-RNA interaction. Analysis for ions at different binding sites shows that the most pronounced water deficiency relative to the fully hydrated state occurs at a radial distance of around 11 A from the center of the ion. Based on the independent 200 ns molecular dynamics simulations for three different RNA structures (Protein Data Bank: 1TRA, 2TPK, and 437D), we find that Mg2+ ions overwhelmingly dominate over monovalent ions such as Na+ and K+ in ion-RNA binding. Furthermore, application of the free energy perturbation method leads to a quantitative relationship between the Mg2+ dehydration free energy and the local structural environment. We find that DeltaDeltaGhyd, the change of the Mg2+ hydration free energy upon binding to RNA, varies linearly with the inverse distance between the Mg2+ ion and the nearby nonbridging oxygen atoms of the phosphate groups, and DeltaDeltaGhyd can reach -2.0 kcal/mol and 3.0 kcal/mol for an Mg2+ ion bound to the surface and to the groove interior, respectively. In addition, the computation results in an analytical formula for the hydration ratio as a function of the average inverse Mg2+-O distance. The results here might be useful for further quantitative investigations of ion-RNA interactions in RNA folding. PMID- 29590587 TI - Cryo-EM Elucidation of the Structure of Bacteriophage P22 Virions after Genome Release. AB - Genome ejection proteins are required to facilitate transport of bacteriophage P22 double-stranded DNA safely through membranes of Salmonella. The structures and locations of all proteins in the context of the mature virion are known, with the exception of three ejection proteins. Furthermore, the changes that occur to the proteins residing in the mature virion upon DNA release are not fully understood. We used cryogenic electron microscopy to obtain what is, to our knowledge, the first asymmetric reconstruction of mature bacteriophage P22 after double-stranded DNA has been extruded from the capsid-a state representative of one step during viral infection. Results of icosahedral and asymmetric reconstructions at estimated resolutions of 7.8 and 12.5 A resolutions, respectively, are presented. The reconstruction shows tube-like protein density extending from the center of the tail assembly. The portal protein does not revert to the more contracted, procapsid state, but instead maintains an extended and splayed barrel structure. These structural details contribute to our understanding of the molecular mechanism of P22 phage infection and also set the foundation for future exploitation serving engineering purposes. PMID- 29590589 TI - Molecular Mechanisms of Tight Binding through Fuzzy Interactions. AB - Many intrinsically disordered proteins (IDPs) form fuzzy complexes upon binding to their targets. Although many IDPs are weakly bound in fuzzy complexes, some IDPs form high-affinity complexes. One example is the nonstructural protein 1 (NS1) of the 1918 Spanish influenza A virus, which hijacks cellular CRKII through the strong binding affinity (Kd ~10 nM) of its proline-rich motif (PRMNS1) to the N-terminal Src-homology 3 domain of CRKII. However, its molecular mechanism remains elusive. Here, we examine the interplay between structural disorder of a bound PRMNS1 and its long-range electrostatic interactions. Using x-ray crystallography and NMR spectroscopy, we found that PRMNS1 retains substantial conformational flexibility in the bound state. Moreover, molecular dynamics simulations showed that structural disorder of the bound PRMNS1 increases the number of electrostatic interactions and decreases the mean distances between the positively charged residues in PRMNS1 and the acidic residues in the N-terminal Src-homology 3 domain. These results are analyzed using a polyelectrostatic model. Our results provide an insight into the molecular recognition mechanism for a high-affinity fuzzy complex. PMID- 29590588 TI - Active Site Flexibility as a Hallmark for Efficient PET Degradation by I. sakaiensis PETase. AB - Polyethylene terephthalate (PET) is one of the most-consumed synthetic polymers, with an annual production of 50 million tons. Unfortunately, PET accumulates as waste and is highly resistant to biodegradation. Recently, fungal and bacterial thermophilic hydrolases were found to catalyze PET hydrolysis with optimal activities at high temperatures. Strikingly, an enzyme from Ideonella sakaiensis, termed PETase, was described to efficiently degrade PET at room temperature, but the molecular basis of its activity is not currently understood. Here, a crystal structure of PETase was determined at 2.02 A resolution and employed in molecular dynamics simulations showing that the active site of PETase has higher flexibility at room temperature than its thermophilic counterparts. This flexibility is controlled by a novel disulfide bond in its active site, with its removal leading to destabilization of the catalytic triad and reduction of the hydrolase activity. Molecular docking of a model substrate predicts that PET binds to PETase in a unique and energetically favorable conformation facilitated by several residue substitutions within its active site when compared to other enzymes. These computational predictions are in excellent agreement with recent mutagenesis and PET film degradation analyses. Finally, we rationalize the increased catalytic activity of PETase at room temperature through molecular dynamics simulations of enzyme-ligand complexes for PETase and other thermophilic PET-degrading enzymes at 298, 323, and 353 K. Our results reveal that both the binding pose and residue substitutions within PETase favor proximity between the catalytic residues and the labile carbonyl of the substrate at room temperature, suggesting a more favorable hydrolytic reaction. These results are valuable for enabling detailed evolutionary analysis of PET-degrading enzymes and for rational design endeavors aiming at increasing the efficiency of PETase and similar enzymes toward plastic degradation. PMID- 29590590 TI - Modulation of DEG/ENaCs by Amphiphiles Suggests Sensitivity to Membrane Alterations. AB - The bile acid-sensitive ion channel is activated by amphiphilic substances such as bile acids or artificial detergents via membrane alterations; however, the mechanism of membrane sensitivity of the bile acid-sensitive ion channel is not known. It has also not been systematically investigated whether other members of the degenerin/epithelial Na+ channel (DEG/ENaC) gene family are affected by amphiphilic compounds. Here, we show that DEG/ENaCs ASIC1a, ASIC3, ENaC, and the purinergic receptor P2X2 are modulated by a large number of different, structurally unrelated amphiphilic substances, namely the detergents N lauroylsarcosine, Triton X-100, and beta-octylglucoside; the fenamate flufenamic acid; the antipsychotic drug chlorpromazine; the natural phenol resveratrol; the chili pepper compound capsaicin; the loop diuretic furosemide; and the antiarrythmic agent verapamil. We determined the modification of membrane properties using large-angle x-ray diffraction experiments on model lipid bilayers, revealing that the amphiphilic compounds are positioned in a characteristic fashion either in the lipid tail group region or in the lipid head group region, demonstrating that they perturbed the membrane structure. Collectively, our results show that DEG/ENaCs and structurally related P2X receptors are modulated by diverse amphiphilic molecules. Furthermore, they suggest alterations of membrane properties by amphiphilic compounds as a mechanism contributing to modulation. PMID- 29590591 TI - Mechanism of Mechanosensitive Gating of the TREK-2 Potassium Channel. AB - The mechanism of mechanosensitive gating of ion channels underlies many physiological processes, including the sensations of touch, hearing, and pain perception. TREK-2 is the best-studied mechanosensitive member of the two-pore domain potassium channel family. Apart from pressure sensing, it responds to a diverse range of stimuli. Two states, termed "up" and "down," are known from x ray structural crystallographic studies and have been suggested to differ in conductance. However, the structural details of the gating behavior are largely unknown. In this work, we used molecular dynamics simulations to study the conductance of the states as well as the effect of mechanical membrane stretch on the channel. We find that the down state is less conductive than the up state. The introduction of membrane stretch in the simulations shifts the state of the channel toward an up configuration, independent of the starting configuration, and also increases its conductance. The correlation of the selectivity filter state and the conductance supports a model in which the selectivity filter gates by a carbonyl flip. This gate is stabilized by the pore helices. We suggest a modulation of these helices by an interface to the transmembrane helices. Membrane pressure changes the conformation of the transmembrane helices directly and consequently also influences the channel conductance. PMID- 29590592 TI - The Phase Behavior and Organization of Sphingomyelin/Cholesterol Membranes: A Deuterium NMR Study. AB - We have studied the dependence of the phase and domain characteristics of sphingomyelin (SM)/cholesterol model membranes on sterol content and temperature using deuterium nuclear magnetic resonance. NMR spectra of N-palmitoyl(D31)-D erythro-sphingosylphosphorylcholine (PSM-d31) were taken for temperatures from 25 to 70 degrees C and cholesterol concentrations of 0-40%. Analogous experiments were performed using 1-palmitoyl,2-palmitoyl(D31)-sn-glycero-3-phosphocholine (DPPC-d31)/cholesterol membranes to carefully compare the data obtained using palmitoyl chains that have similar "kinked" conformations. The constructed phase diagrams exhibit both solid-ordered (so) + liquid-ordered (lo) and liquid disordered (ld) + lo phase-coexistence regions with a clear three-phase line. Macroscopic (micron-sized) coexistence of ld and lo phases was not observed; instead, line-broadening in the ld+lo region was characterized by intermediate exchange of lipids between the two types of domains. The length scales associated with the domains were estimated to be 75-150 nm for PSM-d31/cholesterol and DPPC d31/cholesterol model membranes. PMID- 29590594 TI - A New Method of Assessing Lipid Mixtures by 31P Magic-Angle Spinning NMR. AB - A variety of lipids that differ by their chains and headgroups are found in biomembranes. In addition to studying the overall membrane phase, determination of the structure, dynamics, and headgroup conformation of individual lipids in the mixture would be of great interest. We have thus developed, to our knowledge, a new approach using solid-state 31P NMR, magic-angle spinning, and chemical shift anisotropy (CSA) recoupling, using an altered version of the recoupling of chemical shift anisotropy (ROCSA) pulse sequence, here penned PROCSA. The resulting two-dimensional spectra allowed the simultaneous measurement of the isotropic chemical shift and CSA of each lipid headgroup, thus providing a valuable measure of its dynamics and structure. PROCSA was applied to mixtures of phosphatidylethanolamine (PE) and phosphatidylglycerol (PG) in various relative proportions, to mimic bacterial membranes and assess the respective roles of lipids in shaping these bilayers. The results were interpreted in terms of membrane topology, lipid propensity to adopt various phases or conformations, and lipid-lipid miscibility. Our results showed that PG dictates the lipid behavior when present in a proportion of 20 mol % or more. A small proportion of PG is thus able to impose a bilayer structure to the hexagonal phase forming PE. We discuss the requirement for lipids, such as PE, to be able to adopt non-bilayer phases in a membrane. PMID- 29590593 TI - Toxic HypF-N Oligomers Selectively Bind the Plasma Membrane to Impair Cell Adhesion Capability. AB - The deposition of fibrillar protein aggregates in human organs is the hallmark of several pathological states, including highly debilitating neurodegenerative disorders and systemic amyloidoses. It is widely accepted that small oligomers arising as intermediates in the aggregation process, released by fibrils, or growing in secondary nucleation steps are the cytotoxic entities in protein misfolding diseases, notably neurodegenerative conditions. Increasing evidence indicates that cytotoxicity is triggered by the interaction between nanosized protein aggregates and cell membranes, even though little information on the molecular details of such interaction is presently available. In this work, we propose what is, to our knowledge, a new approach, based on the use of single cell force spectroscopy applied to multifunctional substrates, to study the interaction between protein oligomers, cell membranes, and/or the extracellular matrix. We compared the interaction of single Chinese hamster ovary cells with two types of oligomers (toxic and nontoxic) grown from the N-terminal domain of the Escherichia coli protein HypF. We were able to quantify the affinity between both oligomer type and the cell membrane by measuring the mechanical work needed to detach the cells from the aggregates, and we could discriminate the contributions of the membrane lipid and protein fractions to such affinity. The fundamental role of the ganglioside GM1 in the membrane-oligomers interaction was also highlighted. Finally, we observed that the binding of toxic oligomers to the cell membrane significantly affects the functionality of adhesion molecules such as Arg-Gly-Asp binding integrins, and that this effect requires the presence of the negatively charged sialic acid moiety of GM1. PMID- 29590595 TI - Entropic Control of Receptor Recycling Using Engineered Ligands. AB - Receptor internalization by endocytosis regulates diverse cellular processes, from the rate of nutrient uptake to the timescale of essential signaling events. The established view is that internalization is tightly controlled by specific protein-binding interactions. However, recent work suggests that physical aspects of receptors influence the process in ways that cannot be explained by biochemistry alone. Specifically, work from several groups suggests that increasing the steric bulk of receptors may inhibit their uptake by multiple types of trafficking vesicles. How do biochemical and biophysical factors work together to control internalization? Here, we show that receptor uptake is well described by a thermodynamic trade-off between receptor-vesicle binding energy and the entropic cost of confining receptors within endocytic vesicles. Specifically, using large ligands to acutely increase the size of engineered variants of the transferrin receptor, we demonstrate that an increase in the steric bulk of a receptor dramatically decreases its probability of uptake by clathrin-coated structures. Further, in agreement with a simple thermodynamic analysis, all data collapse onto a single trend relating fractional occupancy of the endocytic structure to fractional occupancy of the surrounding plasma membrane, independent of receptor size. This fundamental scaling law provides a simple tool for predicting the impact of receptor expression level, steric bulk, and the size of endocytic structures on receptor uptake. More broadly, this work suggests that bulky ligands could be used to drive the accumulation of specific receptors at the plasma membrane surface, providing a biophysical tool for targeted modulation of signaling and metabolism from outside the cell. PMID- 29590596 TI - Atomistic Scale Effects of Lipopolysaccharide Modifications on Bacterial Outer Membrane Defenses. AB - Lipopolysaccharides (LPS) are a main constituent of the outer membrane of Gram negative bacteria. Salmonella enterica, like many other bacterial species, are able to chemically modify the structure of their LPS molecules through the PhoPQ pathway as a defense mechanism against the host immune response. These modifications make the outer membrane more resistant to antimicrobial peptides (AMPs), large lipophilic drugs, and cation depletion, and are crucial for survival within a host organism. It is believed that these LPS modifications prevent the penetration of large molecules and AMPs through a strengthening of lateral interactions between neighboring LPS molecules. Here, we performed a series of long-timescale molecular dynamics simulations to study how each of three key S. enterica lipid A modifications affect bilayer properties, with a focus on membrane structural characteristics, lateral interactions, and the divalent cation bridging network. Our results discern the unique impact each modification has on strengthening the bacterial outer membrane through effects such as increased hydrogen bonding and tighter lipid packing. Additionally, one of the modifications studied shifts Ca2+ from the lipid A region, replacing it as a major cross-linking agent between adjacent lipids and potentially making bacteria less susceptible to AMPs that competitively displace cations from the membrane surface. These results further improve our understanding of outer membrane chemical properties and help elucidate how outer membrane modification systems, such as PhoPQ in S. enterica, are able to alter bacterial virulence. PMID- 29590597 TI - The Antiparallel Dimerization of Myosin X Imparts Bundle Selectivity for Processive Motility. AB - Myosin X is an unconventional actin-based molecular motor involved in filopodial formation, microtubule-actin filament interaction, and cell migration. Myosin X is an important component of filopodia regulation, localizing to tips of growing filopodia by an unclear targeting mechanism. The native alpha-helical dimerization domain of myosin X is thought to associate with antiparallel polarity of the two amino acid chains, making myosin X the only myosin that is currently considered to form antiparallel dimers. This study aims to determine if antiparallel dimerization of myosin X imparts selectivity toward actin bundles by comparing the motility of parallel and antiparallel dimers of myosin X on single and fascin-bundled actin filaments. Antiparallel myosin X dimers exhibit selective processivity on fascin-bundled actin and are only weakly processive on single actin filaments below saturating [ATP]. Artificial forced parallel dimers of myosin X are robustly processive on both single and bundled actin, exhibiting no selectivity. To determine the relationship between gating of the reaction steps and observed differences in motility, a mathematical model was developed to correlate the parameters of motility with the biochemical and mechanical kinetics of the dimer. Results from the model, constrained by experimental data, suggest that the probability of binding forward, toward the barbed end of the actin filament, is lower in antiparallel myosin X on single actin filaments compared to fascin-actin bundles and compared to constructs of myosin X with parallel dimerization.

AB - Mycoplasma mobile is a bacterium that uses a unique mechanism to glide on solid surfaces at a velocity of up to 4.5 MUm/s. Its gliding machinery comprises hundreds of units that generate the force for gliding based on the energy derived from ATP; the units catch and pull sialylated oligosaccharides fixed to solid surfaces. In this study, we measured the stall force of wild-type and mutant strains of M. mobile carrying a bead manipulated using optical tweezers. The strains that had been enhanced for binding exhibited weaker stall forces than the wild-type strain, indicating that stall force is related to force generation rather than to binding. The stall force of the wild-type strain decreased linearly from 113 to 19 picoNewtons after the addition of 0-0.5 mM free sialyllactose (a sialylated oligosaccharide), with a decrease in the number of working units. After the addition of 0.5 mM sialyllactose, the cells carrying a bead loaded using optical tweezers exhibited stepwise movements with force increments. The force increments ranged from 1 to 2 picoNewtons. Considering the 70-nm step size, this small-unit force may be explained by the large gear ratio involved in the M. mobile gliding machinery.

AB - The efficiency of intracellular cargo transport from specific sources to target locations is strongly dependent upon molecular motor-assisted motion along the cytoskeleton. Radial transport along microtubules and lateral transport along the filaments of the actin cortex underneath the cell membrane are characteristic for cells with a centrosome. The interplay between the specific cytoskeleton organization and the motor performance results in a spatially inhomogeneous intermittent search strategy. To analyze the efficiency of such intracellular search strategies, we formulate a random velocity model with intermittent arrest states. We evaluate efficiency in terms of mean first passage times for three different, frequently encountered intracellular transport tasks: 1) the narrow escape problem, which emerges during cargo transport to a synapse or other specific region of the cell membrane; 2) the reaction problem, which considers the binding time of two particles within the cell; and 3) the reaction-escape problem, which arises when cargo must be released at a synapse only after pairing with another particle. Our results indicate that cells are able to realize efficient search strategies for various intracellular transport tasks economically through a spatial cytoskeleton organization that involves only a narrow actin cortex rather than a cell body filled with randomly oriented actin filaments. PMID- 29590600 TI - Response of Single Cells to Shock Waves and Numerically Optimized Waveforms for Cancer Therapy. AB - Shock waves are used clinically for breaking kidney stones and treating musculoskeletal indications. The mechanisms by which shock waves interact with tissue are still not well understood. Here, ultra-high-speed imaging was used to visualize the deformation of individual cells embedded in a tissue-mimicking phantom when subject to shock-wave exposure from a clinical source. Three kidney epithelial cell lines were considered to represent normal healthy (human renal epithelial), cancer (CAKI-2), and virus-transformed (HK-2) cells. The experimental results showed that during the compressive phase of the shock waves, there was a small (<2%) decrease in the projected cell area, but during the tensile phase, there was a relatively large (~10%) increase in the projected cell area. The experimental observations were captured by a numerical model with a constitutive material framework consisting of an equation of state for the volumetric response and hyper-viscoelasticity for the deviatoric response. To model the volumetric cell response, it was necessary to change from a higher bulk modulus during the compression to a lower bulk modulus during the tensile shock loading. It was discovered that cancer cells showed a smaller deformation but faster response to the shock-wave tensile phase compared to their noncancerous counterparts. Cell viability experiments, however, showed that cancer cells suffered more damage than other cell types. These data suggest that the cell response to shock waves is specific to the type of cell and waveforms that could be tailored to an application. For example, the model predicts that a shock wave with a tensile stress of 4.59 MPa would increase cell membrane permeability for cancer cells with minimal impact on normal cells. PMID- 29590601 TI - Do Skeletal Dynamics Mediate Sugar Uptake and Transport in Human Erythrocytes? AB - We explore, herein, the hypothesis that transport of molecules or ions into erythrocytes may be affected and directly stimulated by the dynamics of the spectrin/actin skeleton. Skeleton/actin motions are driven by thermal fluctuations that may be influenced by ATP hydrolysis as well as by structural alterations of the junctional complexes that connect the skeleton to the cell's lipid membrane. Specifically, we focus on the uptake of glucose into erythrocytes via glucose transporter 1 and on the kinetics of glucose disassociation at the endofacial side of glucose transporter 1. We argue that glucose disassociation is affected by both hydrodynamic forces induced by the actin/spectrin skeleton and by probable contact of the swinging 37-nm-long F-actin protofilament with glucose, an effect we dub the "stickball effect." Our hypothesis and results are interpreted within the framework of the kinetic measurements and compartmental kinetic models of Carruthers and co-workers; these experimental results and models describe glucose disassociation as the "slow step" (i.e., rate-limiting step) in the uptake process. Our hypothesis is further supported by direct simulations of skeleton-enhanced transport using our molecular-based models for the actin/spectrin skeleton as well as by experimental measurements of glucose uptake into cells subject to shear deformations, which demonstrate the hydrodynamic effects of advection. Our simulations have, in fact, previously demonstrated enhanced skeletal dynamics in cells in shear deformations, as they occur naturally within the skeleton, which is an effect also supported by experimental observations. PMID- 29590602 TI - ECM Cross-Linking Regulates Invadopodia Dynamics. AB - Invadopodia are membrane protrusions dynamically assembled by invasive cancer cells in contact with the extracellular matrix (ECM). Invadopodia are enriched by the structural proteins actin and cortactin as well as metalloproteases such as MT1-MMP, whose function is to degrade the surrounding ECM. During metastasis, invadopodia are necessary for cancer cell intravasation and extravasation. Although signaling pathways involved in the assembly and function of invadopodia are well studied, few studies address invadopodia dynamics and how the cell-ECM interactions contribute to cell invasion. Using iterative analysis based on time lapse microscopy and mathematical modeling of invasive cancer cells, we found that cells oscillate between invadopodia presence and cell stasis-termed the "invadopodia state"-and invadopodia absence during cell translocation-termed the "migration state." Our data suggest that beta1-integrin-ECM binding and ECM cross linking control the duration of each of the two states. By changing the concentration of cross-linkers in two-dimensional and three-dimensional cultures, we generate an ECM in which 0-0.92 of total lysine residues are cross-linked. Using an ECM with a range of cross-linking degrees, we demonstrate that the dynamics of invadopodia-related functions have a biphasic relationship to ECM cross-linking. At intermediate levels of ECM cross-linking (0.39), cells exhibit rapid invadopodia protrusion-retraction cycles and rapid calcium spikes, which lead to more frequent MT1-MMP delivery, causing maximal invadopodia-mediated ECM degradation. In contrast, both extremely high or low levels of cross-linking lead to slower invadopodia-related dynamics and lower ECM degradation. Additionally, beta1-integrin inhibition modifies the dynamics of invadopodia-related functions as well as the length of time cells spend in either of the states. Collectively, these data suggest that beta1-integrin-ECM binding nonlinearly translates small physical differences in the extracellular environment to differences in the dynamics of cancer cell behaviors. Understanding the conditions under which invadopodia can be reduced by subtle environment-targeting treatments may lead to combination therapies for preventing metastatic spread. PMID- 29590603 TI - Gaussian Curvature Directs Stress Fiber Orientation and Cell Migration. AB - We show that substrates with nonzero Gaussian curvature influence the organization of stress fibers and direct the migration of cells. To study the role of Gaussian curvature, we developed a sphere-with-skirt surface in which a positive Gaussian curvature spherical cap is seamlessly surrounded by a negative Gaussian curvature draping skirt, both with principal radii similar to cell length scales. We find significant reconfiguration of two subpopulations of stress fibers when fibroblasts are exposed to these curvatures. Apical stress fibers in cells on skirts align in the radial direction and avoid bending by forming chords across the concave gap, whereas basal stress fibers bend along the convex direction. Cell migration is also strongly influenced by the Gaussian curvature. Real-time imaging shows that cells migrating on skirts repolarize to establish a leading edge in the azimuthal direction. Thereafter, they migrate in that direction. This behavior is notably different from migration on planar surfaces, in which cells typically migrate in the same direction as the apical stress fiber orientation. Thus, this platform reveals that nonzero Gaussian curvature not only affects the positioning of cells and alignment of stress fiber subpopulations but also directs migration in a manner fundamentally distinct from that of migration on planar surfaces. PMID- 29590604 TI - Tissue-Specific Optical Mapping Models of Swine Atria Informed by Optical Coherence Tomography. AB - Computational models and experimental optical mapping of cardiac electrophysiology serve as powerful tools to investigate the underlying mechanisms of arrhythmias. Modeling can also aid the interpretation of optical mapping signals, which may have different characteristics with respect to the underlying electrophysiological signals they represent. However, despite the prevalence of atrial arrhythmias such as atrial fibrillation, models of optical electrical mapping incorporating realistic structure of the atria are lacking. Therefore, we developed image-based models of atrial tissue using structural information extracted from optical coherence tomography (OCT), which can provide volumetric tissue characteristics in high resolution. OCT volumetric data of four swine atrial tissue samples were used to develop models incorporating tissue geometry, tissue-specific myofiber orientation, and ablation lesion regions. We demonstrated the use of these models through electrophysiology and photon scattering simulations. Changes in transmural electrical conduction were observed with the inclusion of OCT-derived, depth-resolved fiber orientation. Additionally, the amplitude of optical mapping signals were not found to correspond with lesion transmurality because of lesion geometry and electrical propagation occurring beyond excitation light penetration. This work established a framework for the development of tissue-specific models of atrial tissue derived from OCT imaging data, which can be useful in future investigations of electrophysiology and optical mapping signals with respect to realistic atrial tissue structure. PMID- 29590605 TI - Matrix Production and Sporulation in Bacillus subtilis Biofilms Localize to Propagating Wave Fronts. AB - Bacterial biofilms are surface-attached microbial communities encased in self produced extracellular polymeric substances. Here we demonstrate that during the development of Bacillus subtilis biofilms, matrix production is localized to an annular front propagating at the periphery and sporulation to a second front at a fixed distance at the interior. We show that within these fronts, cells switch off matrix production and transition to sporulation after a set time delay of ~100 min. Correlation analyses of fluctuations in fluorescence reporter activity reveal that the fronts emerge from a pair of gene-expression waves of matrix production and sporulation. The localized expression waves travel across cells that are immobilized in the biofilm matrix in contrast to active cell migration or horizontal colony spreading. Our results suggest that front propagation arises via a local developmental program occurring at the level of individual bacterial cells, likely driven by nutrient depletion and metabolic by-product accumulation. A single-length scale and timescale couples the spatiotemporal propagation of both fronts throughout development. As a result, gene expression patterns within the advancing fronts collapse to self-similar expression profiles. Our findings highlight the key role of the localized cellular developmental program associated with the propagating front in describing biofilm growth. PMID- 29590606 TI - A Nonquiescent "Idling" Population State in Drug-Treated, BRAF-Mutated Melanoma. AB - Targeted therapy is an effective standard of care in BRAF-mutated malignant melanoma. However, the duration of tumor remission varies unpredictably among patients, and relapse is almost inevitable. Here, we examine the responses of several BRAF-mutated melanoma cell lines (including isogenic subclones) to BRAF inhibitors. We observe complex response dynamics across cell lines, with short term responses (<100 h) varying from cell line to cell line. In the long term, however, we observe equilibration of all drug-treated populations into a nonquiescent state characterized by a balanced rate of death and division, which we term the "idling" state, and to our knowledge, this state has not been previously reported. Using mathematical modeling, we propose that the observed population-level dynamics are the result of cells transitioning between basins of attraction within a drug-modified phenotypic landscape. Each basin is associated with a drug-induced proliferation rate, a recently introduced metric of an antiproliferative drug effect. The idling population state represents a new dynamic equilibrium in which cells are distributed across the landscape such that the population achieves zero net growth. By fitting our model to experimental drug-response data, we infer the phenotypic landscapes of all considered melanoma cell lines and provide a unifying view of how BRAF-mutated melanomas respond to BRAF inhibition. We hypothesize that the residual disease observed in patients after targeted therapy is composed of a significant number of idling cells. Thus, defining molecular determinants of the phenotypic landscape that idling populations occupy may lead to "targeted landscaping" therapies based on rational modification of the landscape to favor basins with greater drug susceptibility. PMID- 29590607 TI - Cas4 Facilitates PAM-Compatible Spacer Selection during CRISPR Adaptation. AB - CRISPR-Cas systems adapt their immunological memory against their invaders by integrating short DNA fragments into clustered regularly interspaced short palindromic repeat (CRISPR) loci. While Cas1 and Cas2 make up the core machinery of the CRISPR integration process, various class I and II CRISPR-Cas systems encode Cas4 proteins for which the role is unknown. Here, we introduced the CRISPR adaptation genes cas1, cas2, and cas4 from the type I-D CRISPR-Cas system of Synechocystis sp. 6803 into Escherichia coli and observed that cas4 is strictly required for the selection of targets with protospacer adjacent motifs (PAMs) conferring I-D CRISPR interference in the native host Synechocystis. We propose a model in which Cas4 assists the CRISPR adaptation complex Cas1-2 by providing DNA substrates tailored for the correct PAM. Introducing functional spacers that target DNA sequences with the correct PAM is key to successful CRISPR interference, providing a better chance of surviving infection by mobile genetic elements. PMID- 29590608 TI - The Murine Natural Cytotoxic Receptor NKp46/NCR1 Controls TRAIL Protein Expression in NK Cells and ILC1s. AB - TRAIL is an apoptosis-inducing ligand constitutively expressed on liver-resident type 1 innate lymphoid cells (ILC1s) and a subset of natural killer (NK) cells, where it contributes to NK cell anti-tumor, anti-viral, and immunoregulatory functions. However, the intrinsic pathways involved in TRAIL expression in ILCs remain unclear. Here, we demonstrate that the murine natural cytotoxic receptor mNKp46/NCR1, expressed on ILC1s and NK cells, controls TRAIL protein expression. Using NKp46-deficient mice, we show that ILC1s lack constitutive expression of TRAIL protein and that NK cells activated in vitro and in vivo fail to upregulate cell surface TRAIL in the absence of NKp46. We show that NKp46 regulates TRAIL expression in a dose-dependent manner and that the reintroduction of NKp46 in mature NK cells deficient for NKp46 is sufficient to restore TRAIL surface expression. These studies uncover a link between NKp46 and TRAIL expression in ILCs with potential implications in pathologies involving NKp46-expressing cells. PMID- 29590609 TI - Repurposing Pan-HDAC Inhibitors for ARID1A-Mutated Ovarian Cancer. AB - ARID1A, a subunit of the SWI/SNF complex, is among the most frequently mutated genes across cancer types. ARID1A is mutated in more than 50% of ovarian clear cell carcinomas (OCCCs), diseases that have no effective therapy. Here, we show that ARID1A mutation confers sensitivity to pan-HDAC inhibitors such as SAHA in ovarian cancers. This correlated with enhanced growth suppression induced by the inhibition of HDAC2 activity in ARID1A-mutated cells. HDAC2 interacts with EZH2 in an ARID1A status-dependent manner. HDAC2 functions as a co-repressor of EZH2 to suppress the expression of EZH2/ARID1A target tumor suppressor genes such as PIK3IP1 to inhibit proliferation and promote apoptosis. SAHA reduced the growth and ascites of the ARID1A-inactivated OCCCs in both orthotopic and genetic mouse models. This correlated with a significant improvement of survival of mice bearing ARID1A-mutated OCCCs. These findings provided preclinical rationales for repurposing FDA-approved pan-HDAC inhibitors for treating ARID1A-mutated cancers. PMID- 29590610 TI - A Transcriptomic Signature of the Hypothalamic Response to Fasting and BDNF Deficiency in Prader-Willi Syndrome. AB - Transcriptional analysis of brain tissue from people with molecularly defined causes of obesity may highlight disease mechanisms and therapeutic targets. We performed RNA sequencing of hypothalamus from individuals with Prader-Willi syndrome (PWS), a genetic obesity syndrome characterized by severe hyperphagia. We found that upregulated genes overlap with the transcriptome of mouse Agrp neurons that signal hunger, while downregulated genes overlap with the expression profile of Pomc neurons activated by feeding. Downregulated genes are expressed mainly in neuronal cells and contribute to neurogenesis, neurotransmitter release, and synaptic plasticity, while upregulated, predominantly microglial genes are involved in inflammatory responses. This transcriptional signature may be mediated by reduced brain-derived neurotrophic factor expression. Additionally, we implicate disruption of alternative splicing as a potential molecular mechanism underlying neuronal dysfunction in PWS. Transcriptomic analysis of the human hypothalamus may identify neural mechanisms involved in energy homeostasis and potential therapeutic targets for weight loss. PMID- 29590611 TI - Nicotinic Acetylcholine Receptors Control Encoding and Retrieval of Associative Recognition Memory through Plasticity in the Medial Prefrontal Cortex. AB - Nicotinic acetylcholine receptors (nAChRs) expressed in the medial prefrontal cortex have critical roles in cognitive function. However, whether nAChRs are required for associative recognition memory and the mechanisms by which nAChRs may contribute to mnemonic processing are not known. We demonstrate that nAChRs in the prefrontal cortex exhibit subtype-specific roles in associative memory encoding and retrieval. We present evidence that these separate roles of nAChRs may rely on bidirectional modulation of plasticity at synaptic inputs to the prefrontal cortex that are essential for associative recognition memory. PMID- 29590612 TI - A Conserved Circadian Function for the Neurofibromatosis 1 Gene. AB - Loss of the Neurofibromatosis 1 (Nf1) protein, neurofibromin, in Drosophila disrupts circadian rhythms of locomotor activity without impairing central clock function, suggesting effects downstream of the clock. However, the relevant cellular mechanisms are not known. Leveraging the discovery of output circuits for locomotor rhythms, we dissected cellular actions of neurofibromin in recently identified substrates. Herein, we show that neurofibromin affects the levels and cycling of calcium in multiple circadian peptidergic neurons. A prominent site of action is the pars intercerebralis (PI), the fly equivalent of the hypothalamus, with cell-autonomous effects of Nf1 in PI cells that secrete DH44. Nf1 interacts genetically with peptide signaling to affect circadian behavior. We extended these studies to mammals to demonstrate that mouse astrocytes exhibit a 24-hr rhythm of calcium levels, which is also attenuated by lack of neurofibromin. These findings establish a conserved role for neurofibromin in intracellular signaling rhythms within the nervous system. PMID- 29590613 TI - A Screen for Candidate Targets of Lysine Polyphosphorylation Uncovers a Conserved Network Implicated in Ribosome Biogenesis. AB - Polyphosphates (polyP) are chains of inorganic phosphates found in all cells. Previous work has implicated these chains in diverse functions, but the mechanism of action is unclear. A recent study reports that polyP can be non-enzymatically and covalently attached to lysine residues on yeast proteins Nsr1 and Top1. One question emerging from this work is whether so-called "polyphosphorylation" is unique to these proteins or instead functions as a global regulator akin to other lysine post-translational modifications. Here, we present the results of a screen for polyphosphorylated proteins in yeast. We uncovered 15 targets including a conserved network of proteins functioning in ribosome biogenesis. Multiple genes contribute to polyphosphorylation of targets by regulating polyP synthesis, and disruption of this synthesis results in translation defects as measured by polysome profiling. Finally, we identify 6 human proteins that can be modified by polyP, highlighting the therapeutic potential of manipulating polyphosphorylation in vivo. PMID- 29590614 TI - Oral Antibiotic Treatment of Mice Exacerbates the Disease Severity of Multiple Flavivirus Infections. AB - Although the outcome of flavivirus infection can vary from asymptomatic to lethal, environmental factors modulating disease severity are poorly defined. Here, we observed increased susceptibility of mice to severe West Nile (WNV), Dengue, and Zika virus infections after treatment with oral antibiotics (Abx) that depleted the gut microbiota. Abx treatment impaired the development of optimal T cell responses, with decreased levels of WNV-specific CD8+ T cells associated with increased infection and immunopathology. Abx treatments that resulted in enhanced WNV susceptibility generated changes in the overall structure of the gut bacterial community and in the abundance of specific bacterial taxa. As little as 3 days of treatment with ampicillin was sufficient to alter host immunity and WNV outcome. Our results identify oral Abx therapy as a potential environmental determinant of systemic viral disease, and they raise the possibility that perturbation of the gut microbiota may have deleterious consequences for subsequent flavivirus infections. PMID- 29590615 TI - Active Maintenance of T Cell Memory in Acute and Chronic Viral Infection Depends on Continuous Expression of FOXO1. AB - Immunity following an acutely resolved infection or the long-term equipoise of chronic viral infections often depends on the maintenance of antigen-specific CD8+ T cells, yet the ongoing transcriptional requirements of these cells remain unclear. We show that active and continuous programming by FOXO1 is required for the functional maintenance of a memory population. Upon Foxo1 deletion following resolution of an infection, memory cells rapidly lost their characteristic gene expression, gradually declined in number, and were impaired in self-renewal. This was extended to chronic infections, as a loss of FOXO1 during a persistent viral infection led to a rapid decline of the TCF7 (a.k.a. TCF1)-expressing memory-like subset of CD8+ T cells. We further establish FOXO1 regulation as a characteristic of human memory CD8+ T cells. Overall, we show that the molecular and functional longevity of a memory T cell population is actively maintained by the transcription factor FOXO1. PMID- 29590616 TI - p53 in Bronchial Club Cells Facilitates Chronic Lung Inflammation by Promoting Senescence. AB - The tumor suppressor p53 limits tumorigenesis by inducing apoptosis, cell cycle arrest, and senescence. Although p53 is known to limit inflammation during tumor development, its role in regulating chronic lung inflammation is less well understood. To elucidate the function of airway epithelial p53 in such inflammation, we subjected genetically modified mice, whose bronchial epithelial club cells lack p53, to repetitive inhalations of lipopolysaccharide (LPS), an exposure that leads to severe chronic bronchitis and airway senescence in wild type mice. Surprisingly, the club cell p53 knockout mice exhibited reduced airway senescence and bronchitis in response to chronic LPS exposure and were significantly protected from global lung destruction. Furthermore, pharmacological elimination of senescent cells also protected wild-type mice from chronic LPS-induced bronchitis. Our results implicate p53 in induction of club cell senescence and correlate epithelial cell senescence of chronic airway inflammation and lung destruction. PMID- 29590617 TI - Regulation of Cellular Senescence by Polycomb Chromatin Modifiers through Distinct DNA Damage- and Histone Methylation-Dependent Pathways. AB - Polycomb group (PcG) factors maintain facultative heterochromatin and mediate many important developmental and differentiation processes. EZH2, a PcG histone H3 lysine-27 methyltransferase, is repressed in senescent cells. We show here that downregulation of EZH2 promotes senescence through two distinct mechanisms. First, depletion of EZH2 in proliferating cells rapidly initiates a DNA damage response prior to a reduction in the levels of H3K27me3 marks. Second, the eventual loss of H3K27me3 induces p16 (CDKN2A) gene expression independent of DNA damage and potently activates genes of the senescence-associated secretory phenotype (SASP). The progressive depletion of H3K27me3 marks can be viewed as a molecular "timer" to provide a window during which cells can repair DNA damage. EZH2 is regulated transcriptionally by WNT and MYC signaling and posttranslationally by DNA damage-triggered protein turnover. These mechanisms provide insights into the processes that generate senescent cells during aging. PMID- 29590618 TI - Telomere Dysfunction Disturbs Macrophage Mitochondrial Metabolism and the NLRP3 Inflammasome through the PGC-1alpha/TNFAIP3 Axis. AB - Immune and inflammation dysregulation have been associated with the aging process and contribute to age-related disorders, but the underlying mechanism remains elusive. Here, we employed late-generation Terc knockout (Terc-/-) mice to investigate the impact of telomere dysfunction on the host defense and function of innate immune cells. Terc-/- mice displayed exaggerated lung inflammation and increased mortality upon respiratory staphylococcal infection, although their pathogen-clearing capacity was uncompromised. Mechanistically, we found that telomere dysfunction caused macrophage mitochondrial abnormality, oxidative stress, and hyperactivation of the NLRP3 inflammasome. The ubiquitin-editing enzyme TNFAIP3, together with PGC-1alpha, was critically involved in the regulation of mitochondrial and inflammatory gene expression and essential for the homeostatic role of telomeres. Together, the study reveals a regulatory paradigm that connects telomeres to mitochondrial metabolism, innate immunity, and inflammation, shedding light on age-related pathologies. PMID- 29590619 TI - Serine Availability Influences Mitochondrial Dynamics and Function through Lipid Metabolism. AB - Cell proliferation can be dependent on the non-essential amino acid serine, and dietary restriction of serine inhibits tumor growth, but the underlying mechanisms remain incompletely understood. Using a metabolomics approach, we found that serine deprivation most predominantly impacts cellular acylcarnitine levels, a signature of altered mitochondrial function. Fuel utilization from fatty acid, glucose, and glutamine is affected by serine deprivation, as are mitochondrial morphological dynamics leading to increased fragmentation. Interestingly, these changes can occur independently of nucleotide and redox metabolism, two known major functions of serine. A lipidomics analysis revealed an overall decrease in ceramide levels. Importantly, supplementation of the lipid component of bovine serum or C16:0-ceramide could partially restore defects in cell proliferation and mitochondrial fragmentation induced by serine deprivation. Together, these data define a role for serine in supporting mitochondrial function and cell proliferation through ceramide metabolism. PMID- 29590620 TI - A Diurnal Rhythm in Brown Adipose Tissue Causes Rapid Clearance and Combustion of Plasma Lipids at Wakening. AB - Many favorable metabolic effects have been attributed to thermogenic activity of brown adipose tissue (BAT). Yet, time of day has rarely been considered in this field of research. Here, we show that a diurnal rhythm in BAT activity regulates plasma lipid metabolism. We observed a high-amplitude rhythm in fatty acid uptake by BAT that synchronized with the light/dark cycle. Highest uptake was found at the onset of the active period, which coincided with high lipoprotein lipase expression and low angiopoietin-like 4 expression by BAT. Diurnal rhythmicity in BAT activity determined the rate at which lipids were cleared from the circulation, thereby imposing the daily rhythm in plasma lipid concentrations. In mice as well as humans, postprandial lipid excursions were nearly absent at waking. We anticipate that diurnal BAT activity is an important factor to consider when studying the therapeutic potential of promoting BAT activity. PMID- 29590621 TI - Supra-barrel Distribution of Directional Tuning for Global Motion in the Mouse Somatosensory Cortex. AB - Rodents explore their environment with an array of whiskers, inducing complex patterns of whisker deflections. Cortical neuronal networks can extract global properties of tactile scenes. In the primary somatosensory cortex, the information relative to the global direction of a spatiotemporal sequence of whisker deflections can be extracted at the single neuron level. To further understand how the cortical network integrates multi-whisker inputs, we imaged and recorded the mouse barrel cortex activity evoked by sequences of multi whisker deflections generating global motions in different directions. A majority of barrel-related cortical columns show a direction preference for global motions with an overall preference for caudo-ventral directions. Responses to global motions being highly sublinear, the identity of the first deflected whiskers is highly salient but does not seem to determine the global direction preference. Our results further demonstrate that the global direction preference is spatially organized throughout the barrel cortex at a supra-columnar scale. PMID- 29590622 TI - Lrit1, a Retinal Transmembrane Protein, Regulates Selective Synapse Formation in Cone Photoreceptor Cells and Visual Acuity. AB - In the vertebrate retina, cone photoreceptors play crucial roles in photopic vision by transmitting light-evoked signals to ON- and/or OFF-bipolar cells. However, the mechanisms underlying selective synapse formation in the cone photoreceptor pathway remain poorly understood. Here, we found that Lrit1, a leucine-rich transmembrane protein, localizes to the photoreceptor synaptic terminal and regulates the synaptic connection between cone photoreceptors and cone ON-bipolar cells. Lrit1-deficient retinas exhibit an aberrant morphology of cone photoreceptor pedicles, as well as an impairment of signal transmission from cone photoreceptors to cone ON-bipolar cells. Furthermore, we demonstrated that Lrit1 interacts with Frmpd2, a photoreceptor scaffold protein, and with mGluR6, an ON-bipolar cell-specific glutamate receptor. Additionally, Lrit1-null mice showed visual acuity impairments in their optokinetic responses. These results suggest that the Frmpd2-Lrit1-mGluR6 axis regulates selective synapse formation in cone photoreceptors and is essential for normal visual function. PMID- 29590623 TI - LRIT1 Modulates Adaptive Changes in Synaptic Communication of Cone Photoreceptors. AB - Cone photoreceptors scale dynamically the sensitivity of responses to maintain responsiveness across wide range of changes in luminance. Synaptic changes contribute to this adaptation, but how this process is coordinated at the molecular level is poorly understood. Here, we report that a cell adhesion-like molecule, LRIT1, is enriched selectively at cone photoreceptor synapses where it engages in a trans-synaptic interaction with mGluR6, the principal receptor in postsynaptic ON-bipolar cells. The levels of LRIT1 are regulated by the neurotransmitter release apparatus that controls photoreceptor output. Knockout of LRIT1 in mice increases the sensitivity of cone synaptic signaling while impairing its ability to adapt to background light without overtly influencing the morphology or molecular composition of photoreceptor synapses. Accordingly, mice lacking LRIT1 show visual deficits under conditions requiring temporally challenging discrimination of visual signals in steady background light. These observations reveal molecular mechanisms involved in scaling synaptic communication in the retina. PMID- 29590624 TI - Upregulation of Microglial ZEB1 Ameliorates Brain Damage after Acute Ischemic Stroke. AB - Microglia are a key immune-competent cell type that respond to environmental and physiological changes during ischemic stroke. However, the molecular mechanisms controlling post-ischemic microglia activity are unclear. Understanding these mechanisms may ultimately reduce disease burden and allow the manipulation of microglia responses to shape the outcomes of stroke. Here, we report that, after experimentally induced stroke, ZEB1 is highly expressed in ipsilateral cerebral hemisphere, where it is upregulated mainly in microglia. Using a conditional transgenic mouse, we found that ZEB1 upregulation in microglia regulates immune responses in the CNS and alleviates brain injury after ischemic stroke. Our data indicate that ZEB1 overexpression mediates microglia responses and, in turn, inhibits the production of astrocytic CXCL1 through the TGF-beta1-dependent pathway. Reduced CXCL1 leads to a decline in neutrophil infiltration into the brain, thereby reducing CNS inflammation. Our results demonstrate the importance of ZEB1 in microglia-orchestrated neuroinflammation and suggest a potential means for reducing stroke-induced neurological injury. PMID- 29590625 TI - Leucine Zipper-Bearing Kinase Is a Critical Regulator of Astrocyte Reactivity in the Adult Mammalian CNS. AB - Reactive astrocytes influence post-injury recovery, repair, and pathogenesis of the mammalian CNS. Much of the regulation of astrocyte reactivity, however, remains to be understood. Using genetic loss and gain-of-function analyses in vivo, we show that the conserved MAP3K13 (also known as leucine zipper-bearing kinase [LZK]) promotes astrocyte reactivity and glial scar formation after CNS injury. Inducible LZK gene deletion in astrocytes of adult mice reduced astrogliosis and impaired glial scar formation, resulting in increased lesion size after spinal cord injury. Conversely, LZK overexpression in astrocytes enhanced astrogliosis and reduced lesion size. Remarkably, in the absence of injury, LZK overexpression alone induced widespread astrogliosis in the CNS and upregulated astrogliosis activators pSTAT3 and SOX9. The identification of LZK as a critical cell-intrinsic regulator of astrocyte reactivity expands our understanding of the multicellular response to CNS injury and disease, with broad translational implications for neural repair. PMID- 29590626 TI - DCC-Mediated Dab1 Phosphorylation Participates in the Multipolar-to-Bipolar Transition of Migrating Neurons. AB - Newborn neurons undergo inside-out migration to their final destinations during neocortical development. Reelin-induced tyrosine phosphorylation of disabled 1 (Dab1) is a critical mechanism controlling cortical neuron migration. However, the roles of Reelin-independent phosphorylation of Dab1 remain unclear. Here, we report that deleted in colorectal carcinoma (DCC) interacts with Dab1 via its P3 domain. Netrin 1, a DCC ligand, induces Dab1 phosphorylation at Y220 and Y232. Interestingly, knockdown of DCC or truncation of its P3 domain dramatically delays neuronal migration and impairs the multipolar-to-bipolar transition of migrating neurons. Notably, the migration delay and morphological transition defects are rescued by the expression of a phospho-mimetic Dab1 or a constitutively active form of Fyn proto-oncogene (Fyn), a member of the Src family tyrosine kinases that effectively induces Dab1 phosphorylation. Collectively, these findings illustrate a DCC-Dab1 interaction that ensures proper neuronal migration during neocortical development. PMID- 29590627 TI - Extracellular Monomeric and Aggregated Tau Efficiently Enter Human Neurons through Overlapping but Distinct Pathways. AB - In Alzheimer's disease, neurofibrillary tangle pathology appears to spread along neuronal connections, proposed to be mediated by the release and uptake of abnormal, disease-specific forms of microtubule-binding protein tau MAPT. It is currently unclear whether transfer of tau between neurons is a toxic gain-of function process in dementia or reflects a constitutive biological process. We report two entry mechanisms for monomeric tau to human neurons: a rapid dynamin dependent phase typical of endocytosis and a second, slower actin-dependent phase of macropinocytosis. Aggregated tau entry is independent of actin polymerization and largely dynamin dependent, consistent with endocytosis and distinct from macropinocytosis, the major route for aggregated tau entry reported for non neuronal cells. Anti-tau antibodies abrogate monomeric tau entry into neurons, but less efficiently in the case of aggregated tau, where internalized tau carries antibody with it into neurons. These data suggest that tau entry to human neurons is a physiological process and not a disease-specific phenomenon.

AB - Fibroblast heterogeneity has long been recognized in mouse and human lungs, homeostasis, and disease states. However, there is no common consensus on fibroblast subtypes, lineages, biological properties, signaling, and plasticity, which severely hampers our understanding of the mechanisms of fibrosis. To comprehensively classify fibroblast populations in the lung using an unbiased approach, single-cell RNA sequencing was performed with mesenchymal preparations from either uninjured or bleomycin-treated mouse lungs. Single-cell transcriptome analyses classified and defined six mesenchymal cell types in normal lung and seven in fibrotic lung. Furthermore, delineation of their differentiation trajectory was achieved by a machine learning method. This collection of single cell transcriptomes and the distinct classification of fibroblast subsets provide a new resource for understanding the fibroblast landscape and the roles of fibroblasts in fibrotic diseases.

AB - Pharmacologic inhibition of LSD1 promotes blast cell differentiation in acute myeloid leukemia (AML) with MLL translocations. The assumption has been that differentiation is induced through blockade of LSD1's histone demethylase activity. However, we observed that rapid, extensive, drug-induced changes in transcription occurred without genome-wide accumulation of the histone modifications targeted for demethylation by LSD1 at sites of LSD1 binding and that a demethylase-defective mutant rescued LSD1 knockdown AML cells as efficiently as wild-type protein. Rather, LSD1 inhibitors disrupt the interaction of LSD1 and RCOR1 with the SNAG-domain transcription repressor GFI1, which is bound to a discrete set of enhancers located close to transcription factor genes that regulate myeloid differentiation. Physical separation of LSD1/RCOR1 from GFI1 is required for drug-induced differentiation. The consequent inactivation of GFI1 leads to increased enhancer histone acetylation within hours, which directly correlates with the upregulation of nearby subordinate genes. PMID- 29590630 TI - Two Differential Binding Mechanisms of FG-Nucleoporins and Nuclear Transport Receptors. AB - Phenylalanine-glycine-rich nucleoporins (FG-Nups) are intrinsically disordered proteins, constituting the selective barrier of the nuclear pore complex (NPC). Previous studies showed that nuclear transport receptors (NTRs) were found to interact with FG-Nups by forming an "archetypal-fuzzy" complex through the rapid formation and breakage of interactions with many individual FG motifs. Here, we use single-molecule studies combined with atomistic simulations to show that, in sharp contrast, FG-Nup214 undergoes a coupled reconfiguration-binding mechanism when interacting with the export receptor CRM1. Association and dissociation rate constants are more than an order of magnitude lower than in the archetypal-fuzzy complex between FG-Nup153 and NTRs. Unexpectedly, this behavior appears not to be encoded selectively into CRM1 but rather into the FG-Nup214 sequence. The same distinct binding mechanisms are unperturbed in O-linked beta-N-acetylglucosamine modified FG-Nups. Our results have implications for differential roles of distinctly spatially distributed FG-Nup?NTR interactions in the cell. PMID- 29590631 TI - Comprehensive Molecular Profiling Identifies FOXM1 as a Key Transcription Factor for Meningioma Proliferation. AB - Meningioma is the most common primary intracranial tumor, but the molecular drivers of aggressive meningioma are incompletely understood. Using 280 human meningioma samples and RNA sequencing, immunohistochemistry, whole-exome sequencing, DNA methylation arrays, and targeted gene expression profiling, we comprehensively define the molecular profile of aggressive meningioma. Transcriptomic analyses identify FOXM1 as a key transcription factor for meningioma proliferation and a marker of poor clinical outcomes. Consistently, we discover genomic and epigenomic factors associated with FOXM1 activation in aggressive meningiomas. Finally, we define a FOXM1/Wnt signaling axis in meningioma that is associated with a mitotic gene expression program, poor clinical outcomes, and proliferation of primary meningioma cells. In summary, we find that multiple molecular mechanisms converge on a FOXM1/Wnt signaling axis in aggressive meningioma. PMID- 29590632 TI - Vitamin D deficiency in the ApcPirc/+ rat does not exacerbate colonic tumorigenesis, while low dietary calcium might be protective. AB - Human studies have shown that individuals with colon cancer tend to have lower serum 25-hydroxy-vitamin D3 [25(OH)D3] levels compared with healthy controls, but whether this link is causative, a result of the disease or an indicator of another factor altogether has yet to be demonstrated. In humans, vitamin D, calcium and UV exposure are inextricably linked; therefore, understanding the individual and combined roles of each of these will require animal models specifically designed to address these questions. To begin to untangle this network, our group has employed the ApcPirc/+ rat, which contains a truncating mutation in the Apc gene, leading to the development of colonic tumors. Our group previously utilized this model to demonstrate that vitamin D supplementation above normal does not reduce colonic tumor burden and, in fact, increased tumor multiplicity in a dose-dependent manner. In the current study, we tested whether vitamin D deficiency plays a causative role in tumor development using two strains which differ in their susceptibility to intestinal tumorigenesis. In the colon, vitamin D deficiency did not increase the development of tumors in either strain, and was actually protective in one strain. Unexpectedly, low dietary calcium combined with vitamin D deficiency significantly suppressed tumor development in the small intestine and colon of both strains. The vast majority of tumors in the human intestine occur in the colon, and we find no evidence to support a direct role of vitamin D deficiency in increasing colonic tumorigenesis, and low calcium might protect against tumor development.This article has an associated First Person interview with the first author of the paper. PMID- 29590633 TI - Disease Ontology: improving and unifying disease annotations across species. AB - Model organisms are vital to uncovering the mechanisms of human disease and developing new therapeutic tools. Researchers collecting and integrating relevant model organism and/or human data often apply disparate terminologies (vocabularies and ontologies), making comparisons and inferences difficult. A unified disease ontology is required that connects data annotated using diverse disease terminologies, and in which the terminology relationships are continuously maintained. The Mouse Genome Database (MGD, http://www.informatics.jax.org), Rat Genome Database (RGD, http://rgd.mcw.edu) and Disease Ontology (DO, http://www.disease-ontology.org) projects are collaborating to augment DO, aligning and incorporating disease terms used by MGD and RGD, and improving DO as a tool for unifying disease annotations across species. Coordinated assessment of MGD's and RGD's disease term annotations identified new terms that enhance DO's representation of human diseases. Expansion of DO term content and cross-references to clinical vocabularies (e.g. OMIM, ORDO, MeSH) has enriched the DO's domain coverage and utility for annotating many types of data generated from experimental and clinical investigations. The extension of anatomy-based DO classification structure of disease improves accessibility of terms and facilitates application of DO for computational research. A consistent representation of disease associations across data types from cellular to whole organism, generated from clinical and model organism studies, will promote the integration, mining and comparative analysis of these data. The coordinated enrichment of the DO and adoption of DO by MGD and RGD demonstrates DO's usability across human data, MGD, RGD and the rest of the model organism database community. PMID- 29590634 TI - Mek1Y130C mice recapitulate aspects of human cardio-facio-cutaneous syndrome. AB - The RAS/MAPK signaling pathway is one of the most investigated pathways, owing to its established role in numerous cellular processes and implication in cancer. Germline mutations in genes encoding members of the RAS/MAPK pathway also cause severe developmental syndromes collectively known as RASopathies. These syndromes share overlapping characteristics, including craniofacial dysmorphology, cardiac malformations, cutaneous abnormalities and developmental delay. Cardio-facio cutaneous syndrome (CFC) is a rare RASopathy associated with mutations in BRAF, KRAS, MEK1 (MAP2K1) and MEK2 (MAP2K2). MEK1 and MEK2 mutations are found in ~25% of the CFC patients and the MEK1Y130C substitution is the most common one. However, little is known about the origins and mechanisms responsible for the development of CFC. To our knowledge, no mouse model carrying RASopathy-linked Mek1 or Mek2 gene mutations has been reported. To investigate the molecular and developmental consequences of the Mek1Y130C mutation, we generated a mouse line carrying this mutation. Analysis of mice from a Mek1 allelic series revealed that the Mek1Y130C allele expresses both wild-type and Y130C mutant forms of MEK1. However, despite reduced levels of MEK1 protein and the lower abundance of MEK1 Y130C protein than wild type, Mek1Y130C mutants showed increased ERK (MAPK) protein activation in response to growth factors, supporting a role for MEK1 Y130C in hyperactivation of the RAS/MAPK pathway, leading to CFC. Mek1Y130C mutant mice exhibited pulmonary artery stenosis, cranial dysmorphia and neurological anomalies, including increased numbers of GFAP+ astrocytes and Olig2+ oligodendrocytes in regions of the cerebral cortex. These data indicate that the Mek1Y130C mutation recapitulates major aspects of CFC, providing a new animal model to investigate the physiopathology of this RASopathy.

PMID- 29590635 TI - Identification of protective postexposure mycobacterial vaccine antigens using an immunosuppression-based reactivation model in the zebrafish. AB - Roughly one third of the human population carries a latent Mycobacterium tuberculosis infection, with a 5-10% lifetime risk of reactivation to active tuberculosis and further spreading the disease. The mechanisms leading to the reactivation of a latent Mycobacterium tuberculosis infection are insufficiently understood. Here, we used a natural fish pathogen, Mycobacterium marinum, to model the reactivation of a mycobacterial infection in the adult zebrafish (Danio rerio). A low-dose intraperitoneal injection (~40 colony-forming units) led to a latent infection, with mycobacteria found in well-organized granulomas surrounded by a thick layer of fibrous tissue. A latent infection could be reactivated by oral dexamethasone treatment, which led to disruption of the granuloma structures and dissemination of bacteria. This was associated with the depletion of lymphocytes, especially CD4+ T cells. Using this model, we verified that ethambutol is effective against an active disease but not a latent infection. In addition, we screened 15 mycobacterial antigens as postexposure DNA vaccines, of which RpfB and MMAR_4207 reduced bacterial burdens upon reactivation, as did the Ag85-ESAT-6 combination. In conclusion, the adult zebrafish-M. marinum infection model provides a feasible tool for examining the mechanisms of reactivation in mycobacterial infections, and for screening vaccine and drug candidates.This article has an associated First Person interview with the first author of the paper. PMID- 29590636 TI - Vangl2 disruption alters the biomechanics of late spinal neurulation leading to spina bifida in mouse embryos. AB - Human mutations in the planar cell polarity component VANGL2 are associated with the neural tube defect spina bifida. Homozygous Vangl2 mutation in mice prevents initiation of neural tube closure, precluding analysis of its subsequent roles in neurulation. Spinal neurulation involves rostral-to-caudal 'zippering' until completion of closure is imminent, when a caudal-to-rostral closure point, 'Closure 5', arises at the caudal-most extremity of the posterior neuropore (PNP). Here, we used Grhl3Cre to delete Vangl2 in the surface ectoderm (SE) throughout neurulation and in an increasing proportion of PNP neuroepithelial cells at late neurulation stages. This deletion impaired PNP closure after the ~25-somite stage and resulted in caudal spina bifida in 67% of Grhl3Cre/+Vangl2Fl/Fl embryos. In the dorsal SE, Vangl2 deletion diminished rostrocaudal cell body orientation, but not directional polarisation of cell divisions. In the PNP, Vangl2 disruption diminished mediolateral polarisation of apical neuroepithelial F-actin profiles and resulted in eversion of the caudal PNP. This eversion prevented elevation of the caudal PNP neural folds, which in control embryos is associated with formation of Closure 5 around the 25-somite stage. Closure 5 formation in control embryos is associated with a reduction in mechanical stress withstood at the main zippering point, as inferred from the magnitude of neural fold separation following zippering point laser ablation. This stress accommodation did not happen in Vangl2-disrupted embryos. Thus, disruption of Vangl2-dependent planar-polarised processes in the PNP neuroepithelium and SE preclude zippering point biomechanical accommodation associated with Closure 5 formation at the completion of PNP closure. PMID- 29590637 TI - The role of the microRNA-146a/complement factor H/interleukin-1beta-mediated inflammatory loop circuit in the perpetuate inflammation of chronic temporal lobe epilepsy. AB - Increasing evidence indicates that neuroinflammation plays a crucial role in the pathogenesis of temporal lobe epilepsy (TLE). However, it is unclear how the perpetuate inflammation develops. Some recent studies have suggested the possible involvement of microRNA-146a (miR-146a) in the modulation of inflammatory signaling occurring in TLE. To understand how miR-146a modulates inflammatory signaling in TLE, we investigated the role of interleukin-1beta (IL-1beta), miR 146a and human complement factor H (CFH) in the perpetuate inflammation in rat models of chronic TLE and U251 cells. We found that enhancive miR-146a could upregulate the expression of IL-1beta and downregulate the expression of CFH, whereas reductive miR-146a could downregulate the expression of IL-1beta and upregulate the expression of CFH, in hippocampi of chronic TLE rat models. Meanwhile, enhancive miR-146a could increase the abnormal wave forms in the chronic TLE rat models. Additionally, enhancive IL-1beta could feedback downregulate the expression of CFH, upregulate the expression of miR-146a and increase the abnormal wave forms in chronic TLE rat models. After CFH gene knockdown in U251 cells, enhancive miR-146a did not upregulate the expression of IL-1beta. In summary, this study shows that enhancive miR-146a can upregulate the inflammatory factor IL-1beta in chronic TLE by downregulating CFH, and that upregulation of IL-1beta plays an important feedback-regulating role in the expression of miR-146a and CFH, forming a miR-146a-CFH-IL-1beta loop circuit that initiates a cascade of inflammation and then leads to the perpetuate inflammation in TLE. Therefore, modulation of the miR-146a-CFH-IL-1beta loop circuit could be a novel therapeutic target for TLE. PMID- 29590638 TI - Feeding difficulties, a key feature of the Drosophila NDUFS4 mitochondrial disease model. AB - Mitochondrial diseases are associated with a wide variety of clinical symptoms and variable degrees of severity. Patients with such diseases generally have a poor prognosis and often an early fatal disease outcome. With an incidence of 1 in 5000 live births and no curative treatments available, relevant animal models to evaluate new therapeutic regimes for mitochondrial diseases are urgently needed. By knocking down ND-18, the unique Drosophila ortholog of NDUFS4, an accessory subunit of the NADH:ubiquinone oxidoreductase (Complex I), we developed and characterized several dNDUFS4 models that recapitulate key features of mitochondrial disease. Like in humans, the dNDUFS4 KD flies display severe feeding difficulties, an aspect of mitochondrial disorders that has so far been largely ignored in animal models. The impact of this finding, and an approach to overcome it, will be discussed in the context of interpreting disease model characterization and intervention studies.This article has an associated First Person interview with the first author of the paper. PMID- 29590639 TI - Neutrophil-specific knockout demonstrates a role for mitochondria in regulating neutrophil motility in zebrafish. AB - Neutrophils are fast-moving cells essential for host immune functions. Although they primarily rely on glycolysis for ATP, isolated primary human neutrophils depend on mitochondrial membrane potential for chemotaxis. However, it is not known whether mitochondria regulate neutrophil motility in vivo, and the underlying molecular mechanisms remain obscure. Here, we visualized mitochondria in an interconnected network that localizes to the front and rear of migrating neutrophils using a novel transgenic zebrafish line. To disrupt mitochondrial function genetically, we established a gateway system harboring the CRISPR/Cas9 elements for tissue-specific knockout. In a transgenic line, neutrophil-specific disruption of mitochondrial DNA polymerase, polg, significantly reduced the velocity of neutrophil interstitial migration. In addition, inhibiting the mitochondrial electron transport chain or the enzymes that reduce mitochondrial reactive oxygen species also inhibited neutrophil motility. The reduced cell motility that resulted from neutrophil-specific knockout of sod1 was rescued with sod1 mRNA overexpression, or by treating with scavengers of reactive oxygen species. Together, our work has provided the first in vivo evidence that mitochondria regulate neutrophil motility, as well as tools for the functional characterization of mitochondria-related genes in neutrophils and insights into immune deficiency seen in patients with primary mitochondrial disorders.This article has an associated First Person interview with the first author of the paper. PMID- 29590640 TI - Intestinal epithelial cell polarity defects in disease: lessons from microvillus inclusion disease. AB - The intestinal epithelium is a highly organized tissue. The establishment of epithelial cell polarity, with distinct apical and basolateral plasma membrane domains, is pivotal for both barrier formation and for the uptake and vectorial transport of nutrients. The establishment of cell polarity requires a specialized subcellular machinery to transport and recycle proteins to their appropriate location. In order to understand and treat polarity-associated diseases, it is necessary to understand epithelial cell-specific trafficking mechanisms. In this Review, we focus on cell polarity in the adult mammalian intestine. We discuss how intestinal epithelial polarity is established and maintained, and how disturbances in the trafficking machinery can lead to a polarity-associated disorder, microvillus inclusion disease (MVID). Furthermore, we discuss the recent developments in studying MVID, including the creation of genetically manipulated cell lines, mouse models and intestinal organoids, and their uses in basic and applied research.

AB - Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) refer to a group of heterogeneous cancers of neuroendocrine cell phenotype that mainly fall into one of two subtypes: gastroenteropancreatic neuroendocrine tumors (GEP-NETs; well differentiated) or gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs; poorly differentiated). Although originally defined as orphan cancers, their steadily increasing incidence highlights the need to better understand their etiology. Accumulating epidemiological and clinical data have shed light on the pathological characteristics of these diseases. However, the relatively low number of patients has hampered conducting large-scale clinical trials and hence the development of novel treatment strategies. To overcome this limitation, tractable disease models that faithfully reflect clinical features of these diseases are needed. In this Review, we summarize the current understanding of the genetics and biology of these diseases based on conventional disease models, such as genetically engineered mouse models (GEMMs) and cell lines, and discuss the phenotypic differences between the models and affected humans. We also highlight the emerging disease models derived from human clinical samples, including patient-derived xenograft models and organoids, which may provide biological and therapeutic insights into GEP-NENs. PMID- 29590644 TI - Acetylation of GATA4 on Lysine Residue K313 Promotes Osteoblastic Cells Growth. AB - BACKGROUND/AIMS: GATA4, a protein related to osteoblast differentiation and mineralization, whose acetylation is essential for cardiac defects. Here, we aimed to explore the functional impacts of GATA4 acetylation on osteoporosis (OS). METHODS: GATA4 acetylation in hFOB1.19 and 293T cells was detected after exposure of HDAC inhibitors (TSA and SAHA). Co-immunoprecipitation was conducted to determine which HATs and HDACs was involved in the modulation of GATA4 acetylation/deacetylation, and to identify the acetylation site. The transcriptional activity of GATA4 was measured in the presence or absence of cycloheximide. Furthermore, hFOB1.19 cells viability and apoptosis were evaluated after transfection with acetylation-defective mutant of GATA4. RESULTS: As a result, GATA4 acetylation was identified as a pivotal event in hFOB1.19 cells. GATA4 can be acetylated by P300/CBP, and the acetylation site was on lysine residue K313. Besides, the acetylation of GATA4 can be impaired by HDAC1, rather than by HDAC2-5. GATA4 acetylation contributed to the stability and transcription of GATA4. Moreover, GATA4 acetylation activated CCND2 transcription, and mutation of GATA4 on K-313 reduced cell viability and increased a mitochondria-dependent apoptosis in hFOB1.19 cells. CONCLUSION: Our data suggest that GATA4 exists as an acetylated protein in hFOB1.19 cells. Acetylation regulates the stability and transcription of GATA4, and activates CCND2 transcription, which may explain the growth-promoting functions of GATA4 in hFOB1.19 cells. PMID- 29590642 TI - Use of zebrafish to study Shigella infection. AB - Shigella is a leading cause of dysentery worldwide, responsible for up to 165 million cases of shigellosis each year. Shigella is also recognised as an exceptional model pathogen to study key issues in cell biology and innate immunity. Several infection models have been useful to explore Shigella biology; however, we still lack information regarding the events taking place during the Shigella infection process in vivo Here, we discuss a selection of mechanistic insights recently gained from studying Shigella infection of zebrafish (Danio rerio), with a focus on cytoskeleton rearrangements and cellular immunity. We also discuss how infection of zebrafish can be used to investigate new concepts underlying infection control, including emergency granulopoiesis and the use of predatory bacteria to combat antimicrobial resistance. Collectively, these insights illustrate how Shigella infection of zebrafish can provide fundamental advances in our understanding of bacterial pathogenesis and vertebrate host defence. This information should also provide vital clues for the discovery of new therapeutic strategies against infectious disease in humans. PMID- 29590645 TI - PKCepsilon Increases Extracellular Elastin and Fibulin-5/DANCE in Dermal Fibroblasts. AB - BACKGROUND/AIMS: In the earlier study, the selective PKCepsilon activator DCP-LA increased elastic fibres in the dermis of HR-1 hairless mice. As a process of elastic fibre formation, tropoelastin, an elastin monomer, is secreted into the extracellular space. Secreted tropoelastin is delivered to the microfibrils by fibulin-5/developmental arteries and neural crest epidermal growth factor-like (DANCE) and undergoes self-association. Then, tropoelastin assembles around the microfibrils, growing into elastin and elastic fibres by lysyl oxidase (LOX)- or LOX-like (LOXL)-mediated cross-linking. The present study was conducted to understand the mechanism underlying DCP-LA-induced increase in elastin/elastic fibre. METHODS: Western blotting, immunocytochemistory, and real-time reverse transcription-polymerase chain reaction (RT-PCR) were carried out in cultured human dermal fibroblasts. PKCepsilon, mammalian target of rapamycin complex (mTOR), and p70 S6 kinase (S6K) were knocked-down by transfecting each siRNA. RESULTS: DCP-LA increased elastin and fibulin-5/DANCE in a treatment time (6-24 h)- and a bell-shaped concentration (1 nM-1 uM)-dependent manner in the culture medium of human dermal fibroblasts. DCP-LA markedly increased elastic fibres in the extracellular space of cultured fibroblasts. DCP-LA-induced increase in extracellular elastin and fibulin-5/DANCE was abolished by a PKC inhibitor or knocking-down PKCepsilon. DCP-LA did not affect expression of mRNAs for tropoelastin and fiblin-5/DANCE in cultured fibroblasts. DCP-LA-induced increase in extracellular elastin and fibulin-5/DANCE was not inhibited by the protein synthesis inhibitor cycloheximide or by knocking-down mTOR and S6K. DCP-LA never increased extracellular elastin in the presence of elastase, that breaks down elastin. An inhibitor of matrix metalloproteinase 9, that degrades multiple extracellular matrix components including elastin, had no effect on the basal levels and the DCP-LA-induced increase levels of extracellular elastin. CONCLUSION: The results of the present study indicate that PKCepsilon, activated by DCP-LA, increases elastin and fibulin-5/DANCE in the extracellular space of cultured fibroblasts by the mechanism independent of transcriptional and translational modulation or inhibition of elastolysis. PMID- 29590646 TI - Human Glioblastoma-Derived Mesenchymal Stem Cell to Pericytes Transition and Angiogenic Capacity in Glioblastoma Microenvironment. AB - BACKGROUND/AIMS: Tumor vascular formation and maintenance are crucial events in glioblastoma development. Mesenchymal stem cells (MSCs) have been shown to differentiate into pericytes and contribute to neovascularization in the glioma microenvironment. Moreover, glioblastoma-derived mesenchymal stem cells (gb MSCs), which consist of CD90-MSCs and CD90+MSCs, are a subpopulation of MSCs that are more active in glioma vascularization. However, the functions of gb-MSCs and the microRNA (miRNA) modifications in the glioblastoma microenvironment have not yet been fully elucidated. Here, we focus on the pericyte differentiation potential of gb-MSCs and miRNA modifications in gb-MSCs during new vascular formation and glioblastoma growth. METHODS: In vitro, surface markers of gb-MSCs were detected by flow cytometry; the differentiation potential was evaluated by Oil Red O staining, Alizarin Red staining and Alcian blue staining; the proliferation and migration of gb-MSCs in different conditioned media were analyzed by the cck8 test and wound-healing assay, respectively; gb-MSC to pericyte transition was detected by immunofluorescence staining and western blot assay; angiogenetic capacity was analyzed by tube formation assay; and levels of cytokines in different supernatant were determined by ELISA. Additionally, RNA was isolated from gb-MSCs, and miRNA modifications were analyzed using the RAffymetrix miRNA microarray Results: We showed that glioblastoma-conditioned medium increased gb-MSC proliferation and migration and was capable of inducing gb-MSC differentiation into pericytes. Glioblastoma secreted angiogenic factors and gb-MSCs incubated in malignant glioblastoma-conditioned medium formed more tube-like structures, and these cells also adhered to tube-like vessels formed by human umbilical vein endothelial cells (HUVECs) on Matrigel to maintain tumor vascular structure in vitro. miRNA expression were also modified in gb-MSCs cultured in malignant glioblastoma-conditioned medium in vitro. CONCLUSION: These results provide new insight into the functional effects of a subpopulation of MSCs in glioblastoma and may help in the development of novel therapies for solid tumors. PMID- 29590647 TI - MiR-142-3p Inhibits TGF-beta3-Induced Blood-Testis Barrier Impairment by Targeting Lethal Giant Larvae Homolog 2. AB - BACKGROUND/AIMS: Transforming growth factor-beta3 (TGF-beta3) has been proved to perturb the blood-testis barrier (BTB) by accelerating junction protein endocytosis in Sertoli cells (SCs) to accommodate the traversing of preleptotene spermatocytes across the BTB around stage VIII in rat. Yet the molecular network underlying the impairment of TGF-beta3 on BTB integrity is not fully elucidated. Our study herein was designed to investigate the participation of microRNA-142-3p (miR-142-3p), which has been reported to affect TGF-beta3 signaling via different pathways, during BTB dynamics and the corresponding mechanisms. METHODS: MiRNA mimic or agomiRNA was co-administered with or without TGF-beta3 in the cultured SCs or in the rat testis. The SC permeability barrier function was reflected by measuring the transepithelial resistance (TER) and the permeability of the sodium fluorescein (Na-F). The BTB integrity was detected by the permeation of biotin. A luciferase reporter assay was used to testify the potential target of miR-142-3p, lethal giant larvae 2 (Lgl2). Laser capture microdissection (LCM) was applied to acquire cell components of different stages of seminiferious tubules, followed by detection of the expression levels of miR-142-3p, TGF-beta3, and Lgl2 by qPCR. The SC barrier function was also detected as above in the presence of TGF-beta3 after Lgl2 knockdown. RESULTS: We revealed a reversion of TGF-beta3-induced BTB impairment after miR-142-3p treatment both in vitro and in vivo. Meanwhile, the activation of Cdc42 and reduction in occludin aroused by TGF-beta3 were also reversed by miR-142-3p. The predicted binding of miR-142-3p with 3'-untranslated region (3'-UTR) of Lgl2, was verified by the luciferase assay. Moreover, an increased Lgl2 level in TGF-beta3-treated SCs was found and correlated stage specific expressions of TGF-beta3, miR-142-3p, and Lgl2 were revealed. Knockdown of Lgl2 in SCs was shown to partially antagonize the BTB disruption mediated by TGF-beta3. CONCLUSIONS: Collectively, our results suggest a resistance of miR-142 3p on the BTB impairment caused by TGF-beta3 during the seminiferous epithelial cycle by targeting Lgl2. PMID- 29590648 TI - Calcium/Calmodulin-Dependent Protein Kinase IV Mediates IFN-gamma-Induced Immune Behaviors in Skeletal Muscle Cells. AB - BACKGROUND/AIMS: Whether calcium/calmodulin-dependent protein kinase IV (CaMKIV) plays a role in regulating immunologic features of muscle cells in inflammatory environment, as it does for immune cells, remains mostly unknown. In this study, we investigated the influence of endogenous CaMKIV on the immunological characteristics of myoblasts and myotubes received IFN-gamma stimulation. METHODS: C2C12 and murine myogenic precursor cells (MPCs) were cultured and differentiated in vitro, in the presence of pro-inflammatory IFN-gamma. CaMKIV shRNA lentivirus transfection was performed to knockdown CaMKIV gene in C2C12 cells. pEGFP-N1-CaMKIV plasmid was delivered into knockout cells for recovering intracellular CaMKIV gene level. CREB1 antagonist KG-501 was used to block CREB signal. qPCR, immunoblot analysis, or immunofluorescence was used to detect mRNA and protein levels of CaMKIV, immuno-molecules, or pro-inflammatory cytokines and chemokines. Co-stimulatory molecules expression was assessed by FACS analysis. RESULTS: IFN-gamma induces the expression or up-regulation of MHC-I/II and TLR3, and the up-regulation of CaMKIV level in muscle cells. In contrast, CaMKIV knockdown in myoblasts and myotubes leads to expression inhibition of the above immuno-molecules. As well, CaMKIV knockdown selectively inhibits pro-inflammatory cytokines/chemokines, and co-stimulatory molecules expression in IFN-gamma treated myoblasts and myotubes. Finally, CaMKIV knockdown abolishes IFN-gamma induced CREB pathway molecules accumulation in differentiated myotubes. CONCLUSIONS: CaMKIV can be induced to up-regulate in muscle cells under inflammatory condition, and positively mediates intrinsic immune behaviors of muscle cells triggered by IFN-gamma. PMID- 29590649 TI - Circulating LncRNAs Analysis in Patients with Type 2 Diabetes Reveals Novel Genes Influencing Glucose Metabolism and Islet beta-Cell Function. AB - BACKGROUND/AIMS: The islet is an important endocrine organ to secrete insulin to regulate the metabolism of glucose and maintain the stability of blood glucose. Long noncoding RNAs (lncRNAs) are involved in a variety of biological functions and play key roles in many diseases, including type 2 diabetes (T2D). The aim of this study was to determine whether lncRNA-p3134 is associated with glucose metabolism and insulin signaling in pancreatic beta cells. METHODS: LncRNA microarray technology was used to identify the differentially expressed circulating lncRNAs in T2D patients. RT-PCR analyses were performed to determine the expression of lncRNA-p3134 in 30 pairs of diabetic and non-diabetic patients. The correlation of lncRNA-p3134 to clinical data from T2D patients was analyzed. LncRNA-p3134 was overexpressed in Min6 cells and db/db mice by adenovirus mediated technology. CCK-8, TUNEL, Western blot, glucose-stimulated insulin secretion (GSIS), ELISAs and immunochemistry were performed to determine the effect of lncRNA-p3134 on proliferation, apoptosis and insulin secretion both in vitro and vivo. RESULTS: The circulating level of lncRNA-p3134 was higher in diabetic patients than in non-diabetic controls and was correlated with fasting blood glucose and HOMA-beta levels. The lncRNA-p3134 had risen by 4 times in serum exosomes but nearly unchanged in exosome-free samples. The secretion of lncRNA-p3134 was dynamically modulated by glucose in both Min6 cells and isolated mouse islet cells. LncRNA-p3134 positively regulate GSIS through promoting of key regulators (Pdx-1, MafA, GLUT2 and Tcf7l2) in beta cells. In addition, the overexpression of lncRNA-p3134 resulted in a decreased apoptosis ratio and partially reversed the glucotoxicity effects on GSIS function in Min6 cells. The restoration of insulin synthesis and secretion the increase of the insulin positive cells areas by upregulation of lncRNA-p3134 in db/db mice confirmed the compensatory role of lncRNA-p3134 to preserve beta-cell function. Furthermore, a protective effect of lncRNA-p3134 on GSIS by positive modulation of PI3K/Akt/mTOR signaling was also confirmed. After blocking the PI3K/AKT signals with their specific inhibitor, the effect of overexpressed lncRNA-p3134 on insulin secretion was obviously attenuated. CONCLUSION: Taken together, the results of this study provide new insights into lncRNA-p3134 regulation in pancreatic beta cells and provide a better understanding of novel mechanism of glucose homeostasis. PMID- 29590650 TI - MiR-27a Promotes Hemin-Induced Erythroid Differentiation of K562 Cells by Targeting CDC25B. AB - BACKGROUND/AIMS: MicroRNAs (miRNAs) play a crucial role in erythropoiesis. MiR 23a~27a~24-2 clusters have been proven to take part in erythropoiesis via some proteins. CDC25B (cell division control Cdc2 phosphostase B) is also the target of mir-27a; whether it regulates erythropoiesis and its mechanism are unknown. METHODS: To evaluate the potential role of miR-27a during erythroid differentiation, we performed miR-27a gain- and loss-of-function experiments on hemin-induced K562 cells. We detected miR-27a expression after hemin stimulation at different time points. At the same time, the gamma-globin gene also was measured via real-time PCR. According to the results of the chips, we screened the target protein of miR-27a through a dual-luciferase reporter assay and identified it via Western blot analyses. To evaluate the function of CDC25B, benzidine staining and flow cytometry were employed to detect the cell differentiation and cell cycle. RESULTS: We found that miR-27a promotes hemin induced erythroid differentiation of human K562 cells by targeting cell division cycle 25 B (CDC25B). Overexpression of miR-27a promotes the differentiation of hemin-induced K562 cells, as demonstrated by gamma-globin overexpression. The inhibition of miR-27a expression suppresses erythroid differentiation, thus leading to a reduction in the gamma-globin gene. CDC25B was identified as a new target of miR-27a during erythroid differentiation. Overexpression of miR-27a led to decreased CDC25B expression after hemin treatment, and CDC25B was up-regulated when miR-27a expression was inhibited. Moreover, the inhibition of CDC25B affected erythroid differentiation, as assessed by gamma-globin expression. CONCLUSION: This study is the first report of the interaction between miR-27a and CDC25B, and it improves the understanding of miRNA functions during erythroid differentiation. PMID- 29590651 TI - The Frequency of Nonsteroidal Anti-Inflammatory Drug Hypersensitivity in Children with Asthma. AB - BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the second-most frequent drug type to cause hypersensitivity reactions in children. Asthma is one of the risk factors for NSAID hypersensitivity (NSAID-H) in adult patients. There are limited number of studies evaluating NSAID-H among children with asthma. Our aim was to assess the frequency of confirmed NSAID-H and evaluate the classification of NSAID-H in children with asthma. METHODS: Patients followed with a diagnosis of asthma in our Pediatric Allergy Clinic were evaluated for NSAID-H. Patients were questioned whether they had used NSAIDs, and if they experienced any reaction with these drugs. A control group was also questioned for reactions to NSAID use. RESULTS: 976 children with asthma and 2,000 healthy children as a control group were included in this study. The mean age of the patients with asthma was 10.61 +/- 4.21 years and 59.5% were male. Ten (1%) had a reaction history to NSAIDs. NSAID-H was confirmed in 9 (0.9%) who were tested with the suspected drugs. Six of these were classified as "single NSAID-induced urticaria/angioedema or anaphylaxis" and 3 were classified as "NSAIDs-exacerbated respiratory disease." In the control group, only 1 subject had a reaction history to acetylsalicylic acid and no reaction developed in the provocation test. CONCLUSIONS: In our study, NSAID-H was found more frequent in children with asthma than in the control group. Children with asthma should be evaluated for reactions to NSAIDs during hospital visits. PMID- 29590652 TI - A Novel Device for Placement of a Secondary Tracheoesophageal Voice Prosthesis: A Preliminary Feasibility Study. AB - BACKGROUND: Tracheoesophageal puncture (TEP) for post-laryngectomy speech rehabilitation can be performed at the time of laryngectomy (primary) or at a subsequent time (secondary). Traditionally, the secondary procedure is performed using a rigid esophagoscope. Diseases like esophageal stricture, limited neck extension, and soft-tissue fibrosis can make this procedure technically challenging or impossible. We developed a novel device to perform a secondary tracheoesophageal puncture using a flexible esophagoscope. OBJECTIVE: To test the feasibility of a novel device used to create a secondary TEP in post-laryngectomy cadavers. METHODS: In this study, we performed a total laryngectomy on 3 fresh cadavers to establish the feasibility of our prototype. In each cadaver, a flexible esophagoscope was passed into the pharynx with the prototype. The prototype was passed through a working port and deployed to distend the esophagus. The puncture was visualized and a wire was passed via the newly established fistula. The device was activated, securing the wire, and then the esophagoscope and device were removed. RESULTS: There was 100% successful deployment of the prototype device, allowing rapid creation of the puncture and security of the guide wire in each cadaver. There was no evidence of collateral mucosal injury or esophageal perforation. CONCLUSIONS: The prototype device offers an alternative method to safely and efficiently perform a secondary TEP without the requirement of rigid esophagoscopy which can sometimes be technically impossible in this patient population. PMID- 29590653 TI - Misleading Allergens in the Diagnosis of Latex Allergy: Profilin and Cross Reactive Carbohydrate Determinants. AB - BACKGROUND: It has been suggested that latex-specific IgE analysis may lead to false-positive results, especially in patients with pollen allergy. In the present study, the reasons underlying clinically irrelevant latex-specific IgE positivity were investigated. METHODS: Thirty patients with latex allergy (group 1), 89 patients sensitised to aeroallergens (group 2a), and 98 healthy individuals without allergy (group 2b) were enrolled. Participants from all 3 groups were subjected to skin prick tests with aeroallergens including latex, latex-specific IgE analysis (ImmunoCAP), and nasal provocation test with latex. All cases demonstrating positive latex-specific IgE also underwent specific IgE tests (ImmunoCAP) with latex profilin, birch pollen profilin, peach lipid transfer protein, and pineapple bromelain as cross-reactive carbohydrate determinants. RESULTS: Comparison of the atopic and healthy control groups showed that the rate of positive latex-specific IgE was significantly higher in group 2a. Latex profilin-, birch pollen profilin-, and bromelain-specific IgE were remarkably higher in group 2a. CONCLUSION: False positivity to latex-specific IgE in ImmunoCAP analysis may be observed in approximately 19% of patients with pollen allergy. Profilins and bromelain are the main contributors to clinically irrelevant positive latex-specific IgE. PMID- 29590654 TI - Identification of Three Novel Frameshift Mutations in the PKD1 Gene in Iranian Families with Autosomal Dominant Polycystic Kidney Disease Using Efficient Targeted Next-Generation Sequencing. AB - BACKGROUND/AIMS: Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common inherited cystic kidney diseases caused by mutations in two large multi-exon genes, PKD1 and PKD2. High allelic heterogeneity and duplication of PKD1 exons 1-32 as six pseudo genes on chromosome 16 complicate molecular analysis of this disease. METHODS: We applied targeted next-generation sequencing (NGS) in 9 non-consanguineous unrelated Iranian families with ADPKD to identify the genes hosting disease-causing mutations. This approach was confirmed by Sanger sequencing. RESULTS: Here, we determined three different novel frameshift mutations and four previously reported nonsense mutations in the PKD1 gene encoding polycystin1 in heterozygotes. CONCLUSION: This study demonstrates the effectiveness of NGS in significantly reducing the cost and time for simultaneous sequence analysis of PKD1 and PKD2, simplifying the genetic diagnostics of ADPKD. Although a probable correlation between the mutation types and phenotypic outcome is possible, however for more extensive studies in future, the consideration of renal hypouricemia (RHUC) and PKD1 coexistence may be helpful. The novel frameshift mutations reported by this study are p. Q1997X, P. D73X and p. V336X. PMID- 29590655 TI - Lipocalin 2 Suppresses Ocular Inflammation by Inhibiting the Activation of NF kappabeta Pathway in Endotoxin-Induced Uveitis. AB - BACKGROUND/AIMS: Lipocalin 2 (LCN2), an important mediator of a variety of cellular processes, is involved in regulating the inflammatory response, but its roles in different inflammatory diseases are controversial. Because the role of LCN2 in ocular inflammation has been unclear until now, we explored the function of LCN2 in lipopolysaccharide (LPS)-induced ocular inflammation in vivo and in vitro. METHODS: Endotoxin-induced uveitis (EIU) was induced in male Sprague Dawley rats by the intravitreal injection of LPS. The expression and location of LCN2 in the retina were detected with western blotting and immunohistochemistry, respectively. We determined the clinical scores for anterior inflammation, quantified the infiltrated inflammatory cells, and measured the pro-inflammatory factors to determine the anti-inflammatory effects of LCN2 in EIU eyes. Cultured primary rat Muller cells were stimulated with LPS and the expression and secretion of LCN2 were measured with real-time PCR, western blotting, and an ELISA. After Muller cells were cotreated with LPS and LCN2 or PBS, the expression and secretion of TNF-alpha, IL-6, and MCP-1 were examined with realtime PCR, western blotting, and ELISAs. Western blotting and immunofluorescence were used to detect the phosphorylation and cellular distribution of nuclear factor kappaB (NF-kappaB) subunit p65. RESULTS: In EIU, the expression of LCN2 was significantly upregulated in the retina, especially in the outer nuclear layer (mainly composed of Muller cells). LPS stimulation of cultured Muller cells also markedly elevated LCN2 expression. Intravitreal injection of LCN2 significantly reduced the clinical scores, inflammatory infiltration, and protein leakage in EIU, which correlated with the reduced levels of proinflammatory factors in the aqueous humor and retina. LCN2 treatment also reduced the expression and secretion of TNF-alpha, IL-6, and MCP-1 in LPS-stimulated Muller cells. LCN2 inhibited the inflammatory response by inhibiting the phosphorylation and translocation of NF-kappaB p65. CONCLUSIONS: LCN2 protects against ocular inflammation, at least in part, by negatively regulating the activation of the NF kappaB signaling pathway. LCN2 may be a promising anti-inflammatory therapy for ocular diseases, such as uveitis. PMID- 29590656 TI - Epiretinal Proliferations Associated with Lamellar Macular Holes: Clinical and Surgical Implications. AB - OBJECTIVES: To describe the prevalence of lamellar hole-associated epiretinal proliferation (LHEP) and to correlate this finding with lamellar macular hole (LMH) morphology and prognosis after a surgical or conservative approach. METHODS: This is a retrospective multicenter case series comprising consecutive LMH patients followed for >=6 months. Serial spectral-domain optical coherence tomographies were evaluated for the presence of epiretinal membrane (ERM) and LHEP, diameter of the LMH aperture, base, and floor thickness. Pars plana vitrectomy with ERM and internal limiting membrane peeling was performed in the surgical cases. RESULTS: A total of 62 eyes from 57 consecutive patients were included. Mean follow-up time was 27.1 +/- 19.8 months. LHEP was observed in 33 (53.2%) eyes. Patients with LMH and LHEP presented a larger external diameter (p = 0.001) and thinner floors (p = 0.018). Twenty-seven (81.8%) of the patients with LMH and LHEP presented a degenerative intraretinal cavitation, compared to 23.3% in the non-LHEP group (p = 0.001). No differences were observed in visual performance or closure rate between the 2 groups after surgery or in the subset of patients followed conservatively. CONCLUSIONS: LHEP was correlated with the anatomical conformation of the LMH, yielding thinner floors and larger external diameters. However, it did not correlate with the anatomical or functional results, both in the patients who underwent surgery and in those managed conservatively. PMID- 29590657 TI - Angiotensin II Suppresses Rev-erbalpha Expression in THP-1 Macrophages via the Ang II Type 1 Receptor/Liver X Receptor alpha Pathway. AB - BACKGROUND/AIMS: Angiotensin II (Ang II) regulates the expression of some core clock genes; excess Ang II leads to atherosclerosis advancement. Macrophage Rev erbalpha mediates clockwork and inflammation, and plays a role in atherosclerotic lesion progression. However, the role of Ang II in regulating Rev-erbalpha expression in macrophages remains unclarified. METHODS: We induced THP-1 macrophages by phorbol 12-myristate 13-acetate and investigated the effect of Ang II on Rev-erbalpha expression via real-time polymerase chain reaction, western blotting and small interfering RNA (siRNA) techniques. The cytotoxicity of the Rev-erbalpha agonist SR9009 was analyzed using a (3-[4,5-dimethylthiazol-2-yl]) 2,5- diphenyltetrazolium bromide assay. RESULTS: Ang II suppressed Rev-erbalpha mRNA and protein expression in THP-1 macrophages in a dose and time dependent manner. This effect was mediated via Ang II type 1 receptor (AT1R), and not Ang II type 2 receptor or peroxisome proliferator-activated receptor gamma (PPARgamma). Consistent with Rev-erbalpha expression regulated by Ang II, the liver X receptor alpha (LXRalpha) protein expression was downregulated in a time dependent manner after Ang II treatment. The activation or silence of LXRalpha significantly increased or decreased Rev-erbalpha expression regulated by Ang II, respectively. This suggests that LXRalpha is involved in the effect of Ang II on Rev-erbalpha expression. MMP-9 mRNA expressions were significantly suppressed by SR9009 in THP-1 and RAW264.7 macrophages; moreover, SR9009-treatment significantly reduced Ang II-induced MMP-9 protein expressions in two types of macrophages. CONCLUSION: Ang II downregulates Rev-erbalpha expression in THP-1 macrophages via the AT1R/LXRalpha pathway. PMID- 29590658 TI - Effects of Fifty-Hertz Electromagnetic Fields on Granulocytic Differentiation of ATRA-Treated Acute Promyelocytic Leukemia NB4 Cells. AB - BACKGROUND/AIMS: Life on Earth is constantly exposed to electromagnetic fields (EMFs) and the effects induced by EMFs on biological systems have been extensively studied producing different and sometimes contradictory results. Extremely low-frequency electromagnetic fields (ELF-EMFs) have shown to play a role in regulating cell proliferation and differentiation, although how EMFs influence these processes remains unclear. Human acute promyelocytic leukemia (APL) cells are characterized by the arrest of differentiation at the promyelocytic stage due to epigenetic perturbations induced by PML/RARalpha fusion protein (Promyelocytic Leukemia protein - PML/Retinoic Acid Receptor alpha - RARalpha). Therapeutic administration of all-trans retinoic acid (ATRA) re establishes the leukemogenic mechanism re-inducing the normal differentiation processes. METHODS: We studied the effects of ELF-EMFs (50 Hz, 2 mT) on the ATRA mediated granulocytic differentiation process of APL NB4 cells (a cell line established from the bone marrow of a patient affected by the acute promyelocytic leukemia) by monitoring cellular proliferation and morphology, nitrob lue tetrazolium (NBT) reduction and the expression of differentiation surface markers. Finally, we investigated mechanisms focusing on reactive oxygen species (ROS) generation and related molecular pathways. RESULTS: ELF-EMF exposure decreases cellular proliferation potential and helps ATRA-treated NB4 cells to mature. Furthermore, the analysis of ROS production and the consequent extracellular signal regulated kinases (ERK1/2) phosphorylation suggest that a changed intracellular oxidative balance may influence the biological effects of ELF-EMFs. CONCLUSIONS: These results indicate that the exposure to ELF-EMF promotes ATRA-induced granulocytic differentiation of APL cells. PMID- 29590659 TI - LncRNA-AK131850 Sponges MiR-93-5p in Newborn and Mature Osteoclasts to Enhance the Secretion of Vascular Endothelial Growth Factor a Promoting Vasculogenesis of Endothelial Progenitor Cells. AB - BACKGROUND/AIMS: In the process of bone development and remodeling, the vasculature is regarded as the communicative network between the bone and neighboring tissues. Recently, it has been reported that the processes of angiogenesis and osteogenesis are coupled temporally and spatially. However, few studies reported the relationship and relevant mechanism between osteoclastogenesis and vasculogenesis. METHODS: Arraystar Mouse lncRNA microarray V3.0 was firstly used to analyze the differentially expressed lncRNA genes in osteoclast different stages during osteoclastogenesis. Cell counting kit 8 (CCK 8) analysis, quantitative real-time polymerase chain reaction (qRT-PCR) analysis, migration and tube formation assays were used to detect impact of osteoclast different stages on the proliferation, differentiation, migration and tube formation of endothelial progenitor cells (EPCs), respectively. Finally, transfection of AK131850 shRNA, miR-93-5p mimic and miR-93-5p inhibitor, qRT-PCR, western blotting, enzyme-linked immunosorbent assay (ELISA), fluorescence in situ hybridization (FISH) and luciferase reporter assay were carried out to dissect molecular mechanisms. RESULTS: In this study, we found that newborn OCs (N-OC) and mature OCs (M-OC) during osteoclastogenesis significantly promoted proliferation, differentiation, migration and tube formation of endothelial progenitor cells (EPCs). Through lncRNA microarray and GO&pathway analysis, we found that AK131850 and co-expressed gene, vascular endothelial growth factor a (VEGFa), were significantly up-regulated in N-OC and M-OC. After inhibition of AK131850 the promoting effect of N-OC and M-OC on EPCs was reversed. Furthermore, we found that AK131850 directly competed miR-93-5p in N-OC and M-OC through sponge, thereby increasing VEGFa transcription, expression and secretion through derepressing of miR-93-5p on VEGFa. CONCLUSION: Our results provided the first finding that lncRNA-AK131850 sponged miR-93-5p in N-OC and M-OC during osteoclastogenesis to enhance the secretion of VEGFa, thus promoting vasculogenesis of EPCs. PMID- 29590660 TI - The Role of Y-Box Binding Protein 1 in Kidney Injury: Friend or Foe? AB - Y-box-binding protein 1 (YB-1) is a multifunctional protein involved in various cellular processes via the transcriptional and translational regulation of target gene expression. YB-1 promotes acute or chronic kidney injury through multiple molecular pathways; however, accumulating evidence suggests that significantly increased YB-1 levels are of great importance in renoprotection. In addition, YB 1 may contribute to obesity-related kidney disease by promoting adipogenesis. Thus, the role of YB-1 in kidney injury is complicated, and no comprehensive review is currently available. In this review, we summarise recent progress in our understanding of the function of YB-1 in kidney injury and provide an overview of the dual role of YB-1 in kidney disease. Moreover, we propose that YB 1 is a potential therapeutic target to restrict kidney disease. PMID- 29590661 TI - Protodioscin Induces Apoptosis Through ROS-Mediated Endoplasmic Reticulum Stress via the JNK/p38 Activation Pathways in Human Cervical Cancer Cells. AB - BACKGROUND/AIMS: Protodioscin (PD) is a steroidal saponin with anti-cancer effects on a number of cancer cells, but the anti-tumor effects and mechanism of action of PD on human cervical cancer cells is unclear. METHODS: We determined cell viability using the MTT assay. Cell death, mitochondrial membrane potential (MMP), intracellular reactive oxygen species (ROS) generation, and endoplasmic reticulum (ER) stress were measured on a flow cytometry. Caspase activation, ER stress, and MMP-dependent apoptosis proteins in cervical cancer cells in response to PD were determined by Western blot analysis. The ability of ATF4 binding to ChIP promoter was measured using the ChIP assay. RESULTS: We demonstrated that PD inhibits cell viability, causes a loss of mitochondrial function, and induces apoptosis, as evidenced by up-regulation of caspase-8, -3, -9, -PARP, and Bax activation, and down-regulation of Bcl-2 expression. PD was shown to induce ROS and the ER stress pathway, including GRP78, p-eIF-2alpha, ATF4, and CHOP. Pre treatment with NAC, a ROS production inhibitor, significantly reduced ER stress and apoptosis-related proteins induced by PD. Transfection of GRP78/CHOP-siRNA effectively inhibited PD-induced ER stress-dependent apoptosis. Moreover, treatment with PD significantly increased p38 and JNK activation. Co administration of a JNK inhibitor (SP600125) or p38 inhibitor (SB203580) abolished cell death and ER stress effects during PD treatment. In addition, PD induced the expression of nuclear ATF4 and CHOP, as well as the binding ability of ATF4 to the CHOP promoter. CONCLUSION: Our results suggest that PD is a promising therapeutic agent for the treatment of human cervical cancer. PMID- 29590662 TI - Urinary Iron Excretion is Associated with Urinary Full-Length Megalin and Renal Oxidative Stress in Chronic Kidney Disease. AB - BACKGROUND/AIMS: Megalin mediates the uptake of glomerular-filtered iron in the proximal tubules. Urinary full length megalin (C-megalin) excretion has been found to be increased in association with megalin-mediated metabolic load to the endo-lysosomal system in proximal tubular epithelial cells (PTECs) of residual nephrons. In the present study, we investigated the association between urinary iron and C-megalin in chronic kidney disease (CKD) patients, and the possible harmful effect of iron in renal tubules. METHODS: Urinary levels of iron and C megalin were measured in 63 CKD patients using automatic absorption spectrometry and a recently-established sandwich ELISA, respectively. RESULTS: Although both urinary C-megalin and urinary total protein levels were correlated with urinary iron (C-megalin: rho = 0.574, p <0.001; total protein: rho = 0.500, p <0.001, respectively), urinary C-megalin alone emerged as an independent factor positively associated with urinary iron (beta = 0.520, p <0.001) (R2 = 0.75, p <0.001). Furthermore, urinary iron was significantly and positively associated with urinary 8-hydroxydeoxyguanosine, an oxidative stress marker, while no association with other markers of renal tubular injury, i.e., beta2-microglobulin and N-acetyl-beta-D-glucosaminidase, was noted. CONCLUSIONS: Our findings suggest that renal iron handling may be associated with megalin-mediated endo-lysosomal metabolic load in PTECs of residual nephrons and oxidative stress in renal tubules. PMID- 29590663 TI - Do Ultra-Low Multidetector Computed Tomography Doses and Iterative Reconstruction Techniques Affect Subjective Classification of Bone Type at Dental Implant Sites? AB - PURPOSE: To investigate whether ultra-low-dose multidetector computed tomography (MDCT) combined with the reconstruction techniques filtered backprojection (FBP), adaptive statistical iterative reconstruction (ASIR), or model-based iterative reconstruction (MBIR) alters the subjective classification of revised Lekholm and Zarb (LZ) bone types at prospective dental implant sites. MATERIALS AND METHODS: Three cadavers underwent a reference MDCT examination using a standard dose volume (CT dose index [CTDIvol]: 29.4 mGy) and reconstructed with FBP in addition to five test protocols (LD1-LD5) using ultra-low doses (CTDIvol: 4.19, 2.64, 0.99, 0.53, and 0.29 mGy, respectively) and reconstructed with FBP, ASIR 50, ASIR 100, and MBIR. Transverse cross-sectional images of the jawbones were obtained, and three examiners subjectively classified the bone type in each image using the revised LZ classification. The bone type classifications obtained using the reference examination were compared with those obtained from the test protocols for each examiner, and kappa statistic was used to analyze the level of agreement between the reference and test protocols. The clinical significance of the differences was analyzed with Wilcoxon signed rank test. RESULTS: Examiners 1 and 2 found moderate to strong agreement between the reference and test protocols, while Examiner 3 found strong to almost perfect agreement (P < .001). The Wilcoxon signed rank test did not demonstrate a clinical significance of the differences between the reference and test protocols for any of the three examiners. CONCLUSION: MDCT dose reductions of up to 99% did not significantly alter the subjective classification of bone at dental implant sites. PMID- 29590664 TI - The Role of Portable Documentation Format in Three-Dimensional Interactive Visualization in Maxillofacial Prosthetics. AB - Although digital technology has advanced the visualization of treatment planning and rehabilitation in prosthodontics, the field of maxillofacial prosthetics is in vital need of an accessible document for exchange of interactive three dimensional (3D) model visualization without requiring installation of any additional software. This article introduces a 3D data documentation method for effective interactive digital visualization in maxillofacial prosthetics using a portable documentation format (PDF). PMID- 29590666 TI - Effect of Premolar Axial Wall Height on Computer-Aided Design/Computer-Assisted Manufacture Crown Retention. AB - PURPOSE: To evaluate the effect of premolar axial wall height on the retention of adhesive, full-coverage, computer-aided design/computer-assisted manufacture (CAD/CAM) restorations. MATERIALS AND METHODS: A total of 48 premolar teeth randomized into four groups (n = 12 per group) received all-ceramic CAD/CAM restorations with axial wall heights (AWH) of 3, 2, 1, and 0 mm and 16-degree total occlusal convergence (TOC). Specimens were restored with lithium disilicate material and cemented with self-adhesive resin cement. Specimens were loaded to failure after 24 hours. RESULTS: The 3- and 2-mm AWH specimens demonstrated significantly greater failure load. Failure analysis suggests a 2-mm minimum AWH for premolars with a TOC of 16 degrees. CONCLUSION: Adhesive technology may compensate for compromised AWH. PMID- 29590667 TI - ? PMID- 29590668 TI - Safety of lumen-apposing stent with or without coaxial plastic stent for endoscopic ultrasound-guided drainage of pancreatic fluid collections: a retrospective study. AB - BACKGROUND: The aim of this study was to evaluate whether the placement of a coaxial double-pigtail plastic stent (DPS) within a lumen-apposing metal stent (LAMS) may improve the safety of endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs). METHODS: This was a retrospective cohort study including patients with PFCs and an indication for transmural drainage. Two strategies (LAMS alone or LAMS plus DPS) were used at the endoscopist's discretion. RESULTS: A total of 41 patients were treated (21 LAMS alone; 20 LAMS plus DPS). The characteristics of the PFCs, and the technical and clinical success rates did not differ between groups. The LAMS alone group had a significantly higher rate of adverse events than the LAMS plus DPS group (42.9 % vs. 10.0 %; P = 0.04). Bleeding was the most frequent adverse event observed. CONCLUSIONS: The addition of a coaxial DPS to LAMS was associated with a lower rate of adverse events in EUS-guided drainage of PFCs. PMID- 29590669 TI - Colonoscopic perforations in the English National Health Service Bowel Cancer Screening Programme. AB - BACKGROUND: Perforation is the most serious adverse event associated with colonoscopy. In this study of data from the English National Health Service Bowel Cancer Screening Programme, we aimed to describe the presentation and management of perforations, and to determine factors associated with poorer outcomes post perforation. METHODS: The medical records of patients with a perforation following the national screening colonoscopy were retrospectively examined. All colonoscopies performed from 02/08/2006 to 13/03/2014 were studied. Bowel Cancer Screening Centres across England were contacted and asked to complete a detailed dataset relating to perforation presentation, management, and outcome. RESULTS: 263 129 colonoscopies were analyzed, and the rate of perforation was 0.06 %. Complete data were reviewed for 117 perforations: 70.1 % of perforations (82/117) occurred during therapeutic colonoscopies; 54.9 % (62/113) of patients with perforations who were admitted to hospital and in whom data were complete underwent surgery; 26.1 % (30/115) of hospitalized patients left the hospital with a stoma and 19.1 % (22/115) developed post-perforation morbidity. Perforations not detected during colonoscopy were significantly more likely to require surgery (P = 0.03). Diagnostic perforations were significantly more likely to require surgery (P = 0.002) and were associated with higher rates of post-perforation morbidity (P = 0.01). At presentation, the presence of abdominal pain (P = 0.01), a pulse rate > 100 beats per minute (P = 0.049), and a respiratory rate > 20 breaths per minute (P = 0.01) were significantly associated with the patient having surgery. CONCLUSIONS: This is the largest retrospective observational case series in Europe to describe post-perforation presentation, management, and outcomes. We have confirmed that perforation leads to surgical intervention, stoma formation, and post-perforation morbidity. Perforations not recognized during the colonoscopy were significantly more likely to require surgery. Diagnostic perforations were at greater risk of requiring surgery and developing post-perforation morbidity. PMID- 29590670 TI - CT-ADP Point-of-Care Assay Predicts 30-Day Paravalvular Aortic Regurgitation and Bleeding Events following Transcatheter Aortic Valve Replacement. AB - BACKGROUND: Paravalvular aortic regurgitation (PVAR) remains a frequent postprocedural concern following transcatheter aortic valve replacement (TAVR). Persistence of flow turbulence results in the cleavage of high-molecular-weight von Willebrand multimers, primary haemostasis dysfunction and may favour bleedings. Recent data have emphasized the value of a point-of-care measure of von Willebrand factor-dependent platelet function (closure time [CT] adenosine diphosphate [ADP]) in the monitoring of immediate PVAR. This study examined whether CT-ADP could detect PVAR at 30 days and bleeding complications following TAVR. METHODS: CT-ADP was assessed at baseline and the day after the procedure. At 30 days, significant PVAR was defined as a circumferential extent of regurgitation more than 10% by transthoracic echocardiography. Events at follow up were assessed according to the Valve Academic Research Consortium-2 consensus classification. RESULTS: Significant PVAR was diagnosed in 44 out of 219 patients (20.1%). Important reduction of CT-ADP could be found in patients without PVAR, contrasting with the lack of CT-ADP improvement in significant PVAR patients. By multivariate analysis, CT-ADP > 180 seconds (hazard ratio [HR]: 5.1, 95% confidence interval [CI]: 2.5-10.6; p < 0.001) and a self-expandable valve were the sole independent predictors of 30-day PVAR. At follow-up, postprocedural CT-ADP >180 seconds was identified as an independent predictor of major/life threatening bleeding (HR: 1.7, 95% CI [1.0-3.1]; p = 0.049). Major/life threatening bleedings were at their highest levels in patients with postprocedural CT-ADP > 180 seconds (35.2 vs. 18.8%; p = 0.013). CONCLUSION: Postprocedural CT-ADP > 180 seconds is an independent predictor of significant PVAR 30 days after TAVR and may independently contribute to major/life threatening bleedings. PMID- 29590671 TI - Primary Graft Dysfunction (PGD) Following Lung Transplantation. AB - Primary graft dysfunction (PGD) is a form of acute lung injury that results from ischemia reperfusion injury (IRI) and is the major cause of early posttransplant morbidity and mortality. Patients who survive PGD have decreased quality of life, an increased risk of chronic lung allograft dysfunction, specifically bronchiolitis obliterans syndrome, and a significantly increased risk of death. In 2017, the International Society for Heart and Lung Transplantation released updated consensus statements on the PGD definition, most up-to-date PGD risk factors, mechanisms of PGD development, and the state-of-the-art for PGD therapeutics. Risk factor identification has led to the development of PGD predictive algorithms, although their clinical utility remains limited. Ongoing areas of controversy and discussion include further refinements to the PGD grading scheme to account for technologic advances such as extracorporeal membrane oxygenation and the increased utilization of high flow nasal cannula, the use of PGD as an outcome measure in clinical trials of ex vivo lung perfusion, enhancement of predictive algorithms incorporating biochemical risk factors, and the need for development of therapies targeted at improving PGD outcomes. PMID- 29590672 TI - Prenatally Diagnosed Single Umbilical Artery (SUA) - Retrospective Analysis of 1169 Fetuses. AB - PURPOSE: The incidence of a fetal single umbilical artery (SUA) is about 0.5 % and has been associated with an increased risk of congenital malformations, fetal aneuploidy and intrauterine growth restriction (IUGR). MATERIALS AND METHODS: A retrospective analysis of 1169 women with singleton pregnancies diagnosed with fetal SUA between 1997 and 2014 in a specialized practice for prenatal diagnostics has been performed. Data was obtained on maternal and fetal findings as well as pregnancy outcome. RESULTS: 989 (84.6 %) fetuses showed an isolated SUA (iSUA) while 180 (15.4 %) presented with SUA and additional structural and/or chromosomal abnormalities. Structural malformations were distributed as follows: 9.0 % cardiovascular, 3.5 % urogenital, 2.9 % musculoskeletal, 3.0 % gastrointestinal and 2.1 % cerebral. 2.1 % of the fetuses had chromosomal aberrations. 50.8 % (49.2 %) of the fetuses were female (male) and right vs. left SUA was found in 64.2 % (35.8 %) of the cases. Fetuses with SUA and additional abnormalities showed lower rates of live births (85.0 % vs. 98.5 %, p < 0.001), a lower median birth weight (2825 g vs. 3220 g, p < 0.001), higher rates of preterm delivery before week 34 + 0 (13.7 % vs. 3.8 %, p < 0.001) and weighed less than the 5th growth percentile in 21.6 % vs. 9.3 % (p < 0.001) of the fetuses with iSUA. In 5.1 % (60) of the children, chromosomal or structural abnormalities were detected post-partum. CONCLUSION: Once fetal SUA is diagnosed, intense sonoanatomy of the fetus is required and, if associated malformations are found, genetic testing must be offered. In iSUA intermittent biometry is recommended for the early detection of IUGR but additional genetic testing is not necessarily recommended. PMID- 29590673 TI - ? PMID- 29590674 TI - [Influence of glucocorticoid therapy on intratherapeutic biodistribution of 131I radioiodine therapy in Graves' disease]. AB - AIM: Radioiodine therapy (RIT) is an important therapeutic method in the definitive treatment of Graves' disease (GD). However, RIT may trigger development of Graves' ophthalmopathy (GO) or exacerbate a pre-existing GO. Therefore, the procedure recommendation of the DGN (German Society of Nuclear Medicine) for RIT of benign thyroid diseases recommends an additional glucocorticoid therapy for patients with pre-existing GO. Aim of this study was to analyze the influence of a protective glucocorticoid therapy on 131I biokinetics during RIT of patients with GD. MATERIAL AND METHODS: In this retrospective analysis 211 patients with GD who underwent RIT without additional thyreostatic medication were examined. To analyze 131I biokinetics the extrapolated maximum uptake (EMU) and the effective half-life of 131I in the thyroid were determined. Patients suffering from GO received glucocorticoids according to a fixed scheme starting one day prior to RIT, patients without GO did not receive glucocorticoids. Subsequently the ratios of values measured during RIT and those measured during radioactive iodine uptake test were compared among the groups. To take into account other factors, the groups were also compared regarding age, weight, TSH, TRAb, TgAb and TPOAb. RESULTS: In patients with additional glucocorticoid therapy, a reduction of the median EMU from 44 % in radioiodine uptake test to 35 % during RIT was observed. The pretherapeutic (47 %) and intratherapeutic (46 %) EMU of the control group without glucocorticoids remained constant. Comparison of the change in the EMU showed a statistically significant difference between both groups (p < 0.001). Comparison of all other parameters including the effective half-life of 131I (p = 0.79) did not show any statistically significant difference. CONCLUSION: The present study suggests that glucocorticoids affect the biokinetics of 131I by reducing its thyroidal uptake. As a result of this study, for patients without antithyroid medication undergoing glucocorticoid therapy, an adjustment of therapeutic 131I activity determined in radioiodine uptake test could be considered. PMID- 29590675 TI - Influence of scan time point and volume of intravenous contrast administration on blood-pool and liver SUVmax and SUVmean in [18F] FDG PET/CT. AB - AIM: To investigate the influence of scan time point and volume of intravenous contrast material in 18F-FDG PET/CT on maximum and mean standardized uptake values (SUVmax/mean) in bloodpool and liver. METHODS: In 120 patients scheduled for routine whole-body 18F-FDG PET/CT the maximum and mean standardized uptake values (SUVmax/SUVmean) in the liver and blood pool were measured after varying scan time-point (delay 0 s-140 s post injectionem) and volume of contrast material (CM; 0 ml, 80 ml, 100 ml of 300 mg/ml of Iodine). Six groups of 20 patients were investigated: (1) without intravenous CM, (2-5) injection of 100 ml CM with a delay of 80 s (2), 100 s (3), 120 s (4), 140 s (5), and 80 ml CM and a delay of 100 s (6). SUVmax, SUVmean, maximum Hounsfield units (HUmax) and average Hounsfield units (HUav) were calculated with the use of manually drawn regions of interests (ROIs) over the aortic arch and healthy liver tissue. RESULTS: SUVmax in bloodpool was significantly higher in group 3, 4 and 6 compared to group 1. Groups 2 and 5 also showed higher mean values of SUVmax, but the difference was not significant. SUVmean in bloodpool was also higher in groups 2, 3, 4, 5 and 6 compared to group 1, but the differences were only statistically significant in group 3. Both SUVmax and SUVmean in healthy liver tissue did not show significant differences when compared to the non contrast-enhanced control group. CONCLUSION: SUVmax and to a lesser extent SUVmean measured in CM enhanced FDG PET/CT in blood pool could be significantly altered in high contrast CT examinations. This should be kept in mind in PET/CT protocols and evaluation relying on SUVmax and SUVmean, for example when used in the assessment of therapy response, especially in highly vascularized tumor lesions. ZIEL:: Das Ziel dieser Studie war den Einfluss von unterschiedlichen Messzeitpunkten und Volumina bei der Gabe von intravenosem Kontrastmittel in der 18F-FDG PET/CT auf SUVmax und SUVmean im Blutpool und Lebergewebe zu untersuchen. METHODEN: In 120 Patienten, geplant fur eine Ganzkorper 18F-FDG -PET/CT, wurden die maximalen und durchschnittlichen standardisierten Aufnahmewerte (SUVmax/SUVmean) in der Leber und im Blutpool, jeweils nach unterschiedlichen Messzeitpunkten (Verzogerung 0 s-140 s post injectionem) und verschiedenen Volumina von Kontrastmittel (KM; 0 ml, 80 ml, 100 ml mit einer Konzentration von 300 mg/ml Jod) gemessen. Sechs Gruppen von je 20 Patienten wurden untersucht: (1) ohne intravenoses KM, (2-5) Injektion von 100 ml KM mit einer Verzogerung von 80 s (2), 100 s (3), 120 s (4), 140 s (5), und 80 ml KM mit einer Verzogerung von 100 s (6). Es wurden jeweils die SUVmax, SUVmean, die maximalen and die durchschnittlichen Hounsfield Einheiten (HUav, HUmax) anhand manuell gezeichneter Bereiche von Interesse (ROIs) im Aortenbogen und im gesunden Lebergewebe berechnet. ERGEBNISSE: Die SUVmax im Blutpool waren im Vergleich zur Gruppe 1 signifikant hoher in Gruppe 3, 4 und 6. Die Gruppen 2 und 5 zeigten ebenfalls hohere Durchschnittswerte von SUVmax, der Unterschied war jedoch nicht signifikant. Die SUVmean im Blutpool waren im Vergleich zur Gruppe 1 ebenfalls hoher in den Gruppen 2, 3, 4, 5 und 6, allerdings waren die Unterschiede nur in Gruppe 3 statistisch signifikant. Im Lebergewebe zeigten sowohl SUVmax, als auch SUVmean keine signifikanten Unterschiede im Vergleich zu der nativen Kontrollgruppe. SCHLUSSFOLGERUNGEN: In der Kontrastmittel-gestutzten FDG PET/CT konnen die SUVmax und in geringerem Ausmabeta auch SUVmean im Blutpool durch Hochkontrast-CT Untersuchungen signifikant beeinflusst werden. Dies sollte bei PET/CT Protokollen bzw. Auswertungen, die auf SUVmax und SUVmean beruhen, berucksichtigt werden, zum Beispiel bei der Beurteilung des Therapieansprechens insbesondere bei stark vaskularisiertem Tumorgewebe. PMID- 29590676 TI - Radiotoxicity of alpha particles versus high and low energy electrons in hypoxic cancer cells. AB - PURPOSE: Hypoxic regions of tumors are less sensitive to radio- and chemotherapy, leading to poor prognosis of patients. One option to overcome the radioresistance is the irradiation of hypoxic tumors with high linear energy transfer (LET) alpha or Auger electronemitters assuming their radiotoxicity would be less dependent on the cellular oxygenation status. Therefore, the aim of the present study was to determine whether irradiation with the intracellularly distributed Auger electron/gamma-emitter 99mTc using the tracer [99mTc]TcHMPAO is a promising therapeutic option for the treatment of hypoxic tumor cells. Thus, the high LET alpha-particleemitter 223Ra ([223Ra]RaCl2) and the low LET beta-emitter 188Re ([188Re]NaReO4) were studied in comparison to [99mTc]Tc-HMPAO. MATERIALS AND METHODS: A431 tumor cells were incubated with [99mTc]Tc-HMPAO (1-20 MBq/2 mL), [223Ra]RaCl2 (1.4-16.3 kBq/2 mL) or [188Re]NaReO4 (0.3-13.7 MBq/2 mL) under normoxic or hypoxic conditions. The degree of radiotoxicity was analyzed using the colony forming assay (CFA), and the intracellular radionuclide uptake of the radiotracers was quantified. RESULTS: Hypoxic A431 cells are less radiosensitive to irradiation with [99mTc]Tc-HMPAO or [188Re]NaReO4 than normoxic ones. In contrast, the radiosensitivity of A431 cells is almost independent of the oxygen status when treated with the [223Ra]RaCl2. CONCLUSIONS: We demonstrate that the Auger electron/gamma-emitter 99mTc ([99mTc]Tc-HMPAO), which does not bound directly to the DNA, is not a promising therapeutic option for hypoxic tumor cells. But the high LET alpha-particle-emitter 223Ra is more suitable for the treatment of hypoxic tumor cells than irradiation with [99mTc]Tc-HMPAO or the low LET bemitter 188Re. ZIELSETZUNG: Hypoxische Tumorregionen sind bei Radio- und Chemotherapie weniger sensitiv als Tumorregionen mit ausreichender Sauerstoffversorgung. Dies verursacht eine schlechte Prognose fur Tumorpatienten. Eine Option die Radioresistenz zu uberwinden, stellt die Bestrahlung mit alpha Partikel-Emittern oder Auger-Elektronen-Emittern mit einem hohen linearen Energietransfer (LET) dar. In dieser Studie soll untersucht werden, ob die Bestrahlung von hypoxischen Tumorzellen mit dem intrazellular aufgenommenen gamma sowie Auger-Elektronen-Emitter 99mTc unter Verwendung des Radiotracers [99mTc]Tc HMPAO eine vielversprechende Therapieoption darstellen konnte. Vergleichend wurde der Hoch-LET alpha-Partikel-Emitter 223Ra ([223Ra]RaCl2) und der Niedrig-LET beta Emitter 188Re ([188Re]NaReO4) eingesetzt. METHODEN: A431 Tumorzellen wurden unter normoxischen oder hypoxischen Kulturbedingungen mit [99mTc]Tc-HMPAO (1-20 MBq/2 ml), [223Ra]RaCl2 (1,4-16,3 kBq/2 ml) und [188Re]NaReO4 (0,3-13,7 MBq/2 ml) inkubiert. Zur Detektion der resultierenden strahlenbiologischen Wirkung wurde der Koloniebildungsassay angewendet. Zusatzlich wurde die intrazellulare Aufnahme der Radiotracer quantifiziert. ERGEBNISSE: Nach Inkubation von [99mTc]Tc-HMPAO sind hypoxische A431-Zellen weniger strahlensensitiv als normoxische Zellen. Im Gegensatz zur Behandlung mit [99mTc]Tc-HMPAO oder [188Re]NaReO4 wurde bei Behandlung mit [223Ra]RaCl2 ein geringerer Einfluss des Sauerstoffstatus auf die Radiosensitivitat von A431-Zellen gefunden. SCHLUSSFOLGERUNG: Damit konnte gezeigt werden, dass der nicht direkt an die DNA gebundene Auger-Elektronen-/ gamma-Emitter 99mTc ([99mTc]Tc-HMPAO) die Radioresistenz von hypoxischen Tumorzellen nicht uberwinden kann. Jedoch stellt der Hoch-LET alpha-Partikel Emitter 223Ra ([223Ra]RaCl2) eine bessere Behandlungsoption dar.

AB - BACKGROUND: Various tasks within health care processes are repetitive and time consuming, requiring personnel who could be better utilized elsewhere. The task of assigning clinical urgency categories to internal patient referrals is one such case of a time-consuming process, which may be amenable to automation through the application of text mining and natural language processing (NLP) techniques. OBJECTIVE: This article aims to trial and evaluate a pilot study for the first component of the task-determining reasons for referrals. METHODS: Text is extracted from scanned patient referrals before being processed to remove nonsensical symbols and identify key information. The processed data are compared against a list of conditions that represent possible reasons for referral. Similarity scores are used as a measure of overlap in terms used in the processed data and the condition list. RESULTS: This pilot study was successful, and results indicate that it would be valuable for future research to develop a more sophisticated classification model for determining reasons for referrals. Issues encountered in the pilot study and methods of addressing them were outlined and should be of use to researchers working on similar problems. CONCLUSION: This pilot study successfully demonstrated that there is potential for automating the assignment of reasons for referrals and provides a foundation for further work to build on. This study also outlined a potential application of text mining and NLP to automating a manual task in hospitals to save time of human resources. PMID- 29590680 TI - Nutrigenomic Information in the openEHR Data Set. AB - BACKGROUND: The traditional concept of personalized nutrition is based on adapting diets according to individual needs and preferences. Discussions about personalized nutrition have been on since the Human Genome Project, which has sequenced the human genome. Thenceforth, topics such as nutrigenomics have been assessed to help in better understanding the genetic variation influence on the dietary response and association between nutrients and gene expression. Hence, some challenges impaired the understanding about the nowadays important clinical data and about clinical data assumed to be important in the future. OBJECTIVE: Finding the main clinical statements in the personalized nutrition field (nutrigenomics) to create the future-proof health information system to the openEHR server based on archetypes, as well as a specific nutrigenomic template. METHODS: A systematic literature search was conducted in electronic databases such as PubMed. The aim of this systemic review was to list the chief clinical statements and create archetype and templates for openEHR modeling tools, namely, Ocean Archetype Editor and Ocean Template Design. RESULTS: The literature search led to 51 articles; however, just 26 articles were analyzed after all the herein adopted inclusion criteria were assessed. Of these total, 117 clinical statements were identified, as well as 27 archetype-friendly concepts. Our group modeled four new archetypes (waist-to-height ratio, genetic test results, genetic summary, and diet plan) and finally created the specific nutrigenomic template for nutrition care. CONCLUSION: The archetypes and the specific openEHR template developed in this study gave dieticians and other health professionals an important tool to their nutrigenomic clinical practices, besides a set of nutrigenomic data to clinical research. PMID- 29590682 TI - Peripheral Oxytocin Predicts Higher-Level Social Cognition in Men Regardless of Empathy Quotient. AB - INTRODUCTION: Pharmaceutical oxytocin (OT) administration is being tested as a novel treatment for social deficits in various psychiatric populations. However, little is known about how naturally occurring variation in peripheral OT relates to differences in social cognition. This study investigates whether healthy individuals with very high or very low levels of empathy differ in endogenous OT and whether OT plasma levels can predict performance in a mentalizing task. METHODS: 40 healthy men were included based upon their score above the 85th or below the 15th percentile of the empathy quotient inventory 1. Participants' abilities to interpret social information was assessed via the Social Detection Task 2. Plasma OT levels were analyzed using enzyme immunoassay. RESULTS: OT plasma levels predicted mentalizing performance for more ambiguous social scenes (i. e., difficult items) for all participants. We found no group differences in OT plasma levels between subjects with high and low empathy. DISCUSSION: These findings confirm a link between peripheral OT and the ability to read subtle nonverbal social cues in healthy individuals, which is independent of self reported empathy.

PMID- 29590684 TI - [Morphological and Quantitative Changes in Retinal and Optic Nerve Vessels in Experimental Glaucoma Model with Elevated IOP for 7 Weeks]. AB - INTRODUCTION: Glaucoma is characterised by progressive loss of retinal ganglion cells and axons. Experimental research has concentrated on understanding the pathophysiological mechanisms involved in glaucomatous damage. It is still a matter of debate whether neurons or capillaries are primarily damaged by elevated intraocular pressure (IOP). The aim of this study was to detect IOP-induced vascular changes in the vessels of the optic nerve head and the main vessels of the retina in vivo. METHODS: Experimental glaucoma was induced in adult Sprague Dawley rats by cauterisation of three episcleral veins of the left eye (n = 3). In vivo, retinal vessel calibre was measured manually using a peripapillary scan with SD-OCT (Heidelberg Engineering) at baseline and after seven weeks of IOP elevation. The animals were then sacrificed and the optic nerve was fixed with 30% glutaraldehyde and cross-sections stained with paraphenylene diamine to mark the vessels. Contralateral eyes served as controls. Pictures were taken and number of vessels, vessel calibre and area were calculated and compared. RESULTS: IOP was significantly elevated (p < 0.001). In optic nerve cross sections, the number of capillaries did not differ significantly between animals with elevated IOP and controls. However, vessel calibre and area were significantly reduced (p < 0.001) in glaucomatous optic nerves. The calibre of the retinal vessels was significantly lowered - by 9.22% (p = 0.021). CONCLUSION: Retinal arterioles and optic nerve capillaries respond sensitively to abnormal pressure elevation in vivo, showing high and early vulnerability. The vascular responses may influence secondary neuronal responses, which culminate in the death of ganglion cells and blindness, as occurs in clinical glaucoma. PMID- 29590685 TI - Skin Ulceration of Eyelids in Atopic Dermatitis. AB - BACKGROUND: Superinfection of atopic dermatitis due to a disturbed skin barrier is well known. Still, affected eyelids with ulceration are rarely described. We present a case series of three patients in different stages of upper eyelid superinfection. HISTORY AND SIGNS: Three males aged 58, 37, and 52 years with clinical symptomatology of gradual expansion of eyelid ulcerations, crusts, and pus were evaluated. In all cases a standard ophthalmologic examination, including a detailed neuro-ophthalmological status, was performed. Consequently, a skin swab was obtained. THERAPY AND OUTCOME: The completed neuro-ophthalmological status and posterior segment findings were unremarkable in all patients. The skin swab results confirmed the presence of Streptococcus pyogenes, Staphylococcus epidermidis, and Staphylococcus aureus, thus necessitating antibiotic therapy. CONCLUSIONS: Superinfected atopic dermatitis can develop massive ulcerations, indicating a swap and empiric therapy. A complete neuro-ophthalmological status is mandatory to exclude the possibility of orbital involvement. Nevertheless, any paradoxical worsening of symptomatology indicates further referral to a dermatologist. PMID- 29590686 TI - [Long-Term Results after Trabeculectomy Combined with Mitomycin C and Ologen Implant]. AB - BACKGROUND: The Ologen implant consists of a biodegradable collagen and glycosaminoglycan and is intended to avoid postoperative bleb scarring or encapsulation. MATERIALS AND METHODS: In a retrospective clinical study, 806 patients with advanced glaucoma were treated with trabeculectomy combined with mitomycin C0.02% and Ologen implant. The follow-up time of the study was 8 years. RESULTS: A long-term reduction of the intraocular pressure below 16 mmHg was achieved in 92.6% of the patients without glaucoma eye drops in the long-term observation period. The rate of complication was very low during the postoperative period and additional surgical procedures for over-filtration with subsequent choroidal detachment were seen in 6.8% of the patients. A failure of the combined operation with phacoemulsification and implantation of an intraocular lens resulted in revision of the bleb or the application of compressive sutures in 3.35% of patients within 8 years. CONCLUSION: The Ologen implant was introduced in glaucoma surgery to increase the effectiveness of trabeculectomy and to reduce the complications. Trabeculectomy combined with mitomycin C0.02% and an Ologen implant provides a satisfactory filtering effect without the undesirable effects of postoperative fibrosis. PMID- 29590687 TI - Comparative Study of the Usefulness of the Binocular Spot Vision Screener Autorefractor in the Detection of Childhood Visual Disorders. AB - BACKGROUND: The Spot Vision Screener (SVS) is designed to detect significant ametropia, anisometropia, and strabismus in non-dilated eyes. This study evaluates the efficacy of the SVS in paediatric visual screening. PATIENTS AND METHODS: All children screened during the paediatric visual screening day in Lausanne in 2016 were evaluated with the SVS, conventional monocular autorefractors, and clinical orthoptic examination. Recommendations for a further eye examination of the SVS were compared with those issued from traditional clinical screenings (monocular refraction and orthoptic examination). RESULTS: One hundred and sixty-eight consecutive children were included. The median age was 3.9 years. The SVS median spherical equivalent (SE) was + 0.25 D OU and it detected seven cases of (4.2%) anisometropia (SE difference >= 1 D). The conventional monocular autorefractor median SE was - 0.13 D OU and 20 cases of anisometropia (11.9%) were detected. Refraction could not be measured in 1.2% of patients with SVS versus 17.2% with monocular refractors. The SVS screened two manifest strabismus cases against five manifest and > 100 latent strabismus with orthoptic examination. As expected, the SVS was unable to assess reactions to monocular occlusion, visual acuity, and stereovision as well as to detect ocular motility disorders without strabismus in the primary position, and missed two cases of abnormal Bruckner reflexes. Overall, the SVS identified 66 suspect patients (39.3%) against 102 (60.7%) after complete clinical examination. CONCLUSIONS: The SVS can be a useful objective screening tool for non ophthalmologists. However, because it fails to detect ocular motility troubles, organic visual acuity loss, or to assess the visual potential, it should only be used in association with a clinical examination, even in routine screening procedures.

AB - BACKGROUND AND AIMS: The study aimed at the reconstruction of the trajectories of participants of a two-year vocational-retraining into new workplaces thereby identifying favourable and risky conditions of the return-to-work process. From a practical point of view the study identified special needs and necessities for after-care facilities. METHODS: A Mixed-Method-Design was used. Quantitatively the follow-up-study included 214 persons who participated for three times on filling out a questionnaire over a period of eighteen months after the end of the vocational retraining. In the qualitative part of the study thirty persons consented to participate in a narrative-episodic interview on their vocational biography, their illness experiences at work and their way back into work. The study focused on the experiences of the participants from within, on their decision-making, coping, and rearrangement processes as well as on the experienced support from family members and rehabilitation professionals. RESULTS: About 75% of the participants of the vocational retraining succeeded in getting a job within the range of 18 months after finishing the retraining. Indicators for successful Return to Work are a high identification with the new vocation, effective coping with the remaining health problems, and an accepted arrangement with the disabilities in the work place and in everyday-life, a positive anticipation of the health condition in the future, and last but not least a satisfying social inclusion. As specific risk constellations for Return to Work emerged a lack of partnership, unfinished mental coping with the illness, negative subjective health prognosis, and a more passive attitude to life. PMID- 29590693 TI - [Quality Performance Measures in Cardiac Rehabilitation - Results of a Delphi Survey of Members of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases (DGPR)]. AB - OBJECTIVE: The present investigation aimed an explorative acquisition of potential performance measures for quantifying the quality of cardiac rehabilitation (CR) for patients under 65 years of age. METHODS: A 4-level web based Delphi survey of physicians, psychologists, and sports or physiotherapists in CR was conducted from April to July in 2016. The experts assessed several parameters of physical performance, social medicine, subjective health and cardiovascular risk factors regarding their suitability as performance measures of CR. RESULTS: Of the 44 predetermined as well as by the participants proposed parameters, 21 parameters (48%) were selected as potential performance measures. Half of these were psychosocial factors. Merely, smoking habits, blood pressure, LDL-cholesterol and maximum capacity on exercise-ECG achieved a consensus (agreement>75% of the respondents). CONCLUSIONS: The experts' choice of performance measures was little consistent. Therefore, a clinical investigation and scientific evaluation of the predefined parameters is essential.

AB - : Clinical presentation of carpal tunnel syndrome may differ in relation to certain factors like sex, age, duration of symptoms and severity of compression. The objective of this study was an investigation into the hypothesis that several distinct factors are predictive of the clinical profile for the condition. The records of 1,117 patients: 909 women (81 %) and 208 men (19 %) with a mean age of 63 years, were analysed. The whole group was divided into subgroups, depending on the variables analysed: sex, age, duration of the condition, severity of symptoms, severity of electrophysiological abnormalities and occurrence or lack of comorbidities. RESULTS: Of all the considered variables, the Levine symptom scores had the greatest impact on the condition's clinical profile: the higher scores the more severe pain, poorer sensation, weaker grip and worse hand function. Also, ages greater than 80 years had a significant negative effect on most of the considered parameters. None of the remaining analysed variables had a substantial impact on the clinical profile of the condition. PMID- 29590697 TI - [Concerning the Wrist-to-Forearm-Ratio of the Median nerve ultrasound is not a suitable method for assessing the success of a carpal tunnel release]. AB - PURPOSE: The primary aim of the study was to analyze whether there is and - if so - how far a correlation between the clinical findings after carpal tunnel release (CTR) for carpal tunnel syndrome (CTS) and the Wrist-to-Forearm-Ratio (WFR) of the median nerve in ultrasound to answer is question whether the WFR can be used in controlling the operative result. PATIENTS AND METHODS: In a prospective study the clinical, electrophysiological, and sonographic data of 40 patients with CTR for CTS were collected preoperative and 3 and 9 months postoperative. The data of 21 patients with 23 operated hands completing the study were analyzed. There were 5 men and 16 women with an average age of 58 years. RESULTS: Neither a correlation between the clinical findings postoperative and the WFR nor the electrophysiological findings postoperative was found. CONCLUSION: Concerning the Wrist-to-Forearm-Ration of the Median nerve ultrasound is not a suitable method for assessing the success of a carpal tunnel release.

AB - OBJECTIVE: This prospective, randomised study examines the effect of standardised cold compression therapy on swelling, pain and functional outcome after division of the transverse carpal ligament in carpal tunnel syndrome in comparison to cooling alone. PATIENTS AND METHODS: Fifty patients for division of the transverse carpal ligament were randomised into two groups. In group 1, postoperative conventional cooling therapy was performed. Group 2 was given standardised cooling and compression therapy with the Cryo/CuffTM-system (3 * 10 min twice daily). Follow-up examinations were performed on days 1, 8 and 21 after the operation. One patient in group 1 and 3 patients in group 2 could not be followed up. Test parameters were pain, swelling, mobility, strength, and the DASH and MHQ score. RESULTS: There were no significant differences between the two groups at any time point. CONCLUSION: In this study, no advantage could be demonstrated for standardised cooling and compression therapy with the Cryo/CuffTM-system in comparison with conventional cooling after division of the transverse carpal ligament. PMID- 29590699 TI - [Midterm results after sole percutaneous treatment for central impression fractures of the base of the middle phalanx]. AB - PURPOSE: This study investigated the midterm results after sole percutaneous treatment for central depression fractures of the base of the middle phalanx. PATIENTS AND METHODS: 19 men and 2 women with an average age of 31.9 (18 - 57) years with a central depression fracture of the middle phalanx treated solely by intramedullary reposition with a bended K-wire and percutaneous K-wire fixation were followed on average of 13.2 (3 - 40) months. RESULTS: At the time of the last follow-up, all patients were able to pursue their previous occupational activity as well as their usual leisure activities and were painfree (VAS 0). The postoperative active flexion of the affected PIP joint was 86 degrees with an average extension deficit of 1 degrees or 93 % of the range of motion of the uninjured PIPJ of the opposite side. Radiologically there was a nice remodeling of the articular surface with no osteoarthrosis. There were no pin-associated complications or wound healing disorders. CONCLUSION: The sole intramedullary reduction with K-wire osteosynthesis is a suitable and reliable method for the treatment of the central impression fracture. Good functional results can be achieved with low surgical effort. PMID- 29590701 TI - A case of severe gouty tophi-induced carpal tunnel syndrome: Operative finding and its outcome. AB - Gout is a disease featuring acute arthritis, joint deformity and severe pain caused through the deposition of monosodium urate crystals in and around synovial tissue 1. Tophi are stone-like deposits of monosodium urate in the soft tissues, synovial tissues, or bones adjacent to the joints. The tophi can compromise joint motion and deteriorate bony structure, finally leading to functional disability. Therefore, early treatment using uric acid lowering agents is standard practice in gout patients to prevent the formation of tophi through controlling uric acid levels.

AB - OBJECTIVE: The fractured base of the middle phalanx was reconstructed in 13 patients using an osteochondral transplant from the carpometacarpal joint surface of the hamate bone. The goal was to restore joint stability with preservation of mobility. Indications were acute and missed isolated destruction of the palmar middle phalanx base >= 30 %. Contraindications were destruction of the head of the proximal phalanx, advanced chondropathy of the head of the proximal phalanx, and extensive soft tissue injury with loss of skin coverage for the proximal interphalangeal joint. SURGICAL TECHNIQUE: In this procedure the fractured middle phalangeal base was debrided and the defect replaced by a size-matched autograft from the dorsal carpometacarpal osteoarticular surface of the hamate bone, which was secured in place with miniscrews. RESULTS: Bone fusion was achieved in 100 % with restoration of joint congruity in 12 of 13 cases and a slight subluxation in one case. Follow-up was possible in 9 cases after 23 (5-51) months. The average range of motion in the reconstructed joint for extension/flexion was 0/9/73 degrees ; grip strength was 82 % of the unaffected side. Five out of 9 patients developed a mild flexion contracture in the PIP joint. The DASH score was 6 (0 33) points, pain at rest was 1 (0-5), and pain at exercise 2 (0-6) on a visual analogue scale from 0-10. All patients were satisfied and willing to undergo the procedure again. According to the literature, reconstruction of the base of the middle phalanx by an osteochondral graft from the hamate bone is a reliable procedure to restore stability and mobility of the joint.

AB - Polytrauma is a term describing patients with injuries involving multiple body regions that compromises function of the body and/or organ involved. The aim of the study was to evaluate the potential role of erythropoietin in predicting poorer outcome in trauma patients. This prospective study included 86 patients admitted to the Emergency Center of Serbia due to polytrauma assigned according to Injury Severity Score (ISS). The patients were further evaluated using the Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores and erythropoietin levels. There was a significant difference among erythropoietin levels at admission, after 48 and 72 hours, and on day 7 of hospital stay, with significantly higher levels in patients with ISS values 49 75. Based on the results, ROC curves were used to identify cut-off levels to predict ISS score with critical clinical course. It was concluded that erythropoietin could be a good marker of injury severity. Further research has to be performed to determine the cut-off values of erythropoietin that are significant for injury severity. PMID- 29590710 TI - Clinical Significance of VEGF-A and Microvessel Density in Diffuse Large B-Cell Lymphoma and Low-Grade Follicular Lymphoma. AB - Angiogenesis is essential for the development, growth and progression of tumors. Although vascular endothelial growth factor (VEGF) is a well-known proangiogenic factor, its impact on lymphoma has not yet been fully clarified. The aim of this study was to evaluate VEGF-A -expression and microvessel density (MVD) in aggressive lymphoma such as diffuse large B-cell lymphoma (DLBCL), in indolent lymphomas such as low-grade follicular lymphoma (FL), and in lymph node reactive follicular hyperplasia (FH). In 80 prospective and retrospective cases (30 DLBCL, 30 FL and 20 FH), CD31 was analyzed by immunohistochemical staining assessing density of blood vessels, as well as the total number of CD31 positive endothelial cells. The results were compared with relevant clinical data. MVD was 85% in FH, followed by 60% in DLBCL and 43% in low-grade FL. VEGF-A was significantly higher in DLBCL than in low-grade FL and FH. A statistically significant association of MVD and VEGF-A with the International Prognostic Index (IPI) was found in DLBCL. High MVD and VEGF-A expression was observed in DLBCL patients with high IPI, while there was no statistically significant association between MVD and VEGF-A with the Follicular Lymphoma International Prognostic Index in low-grade FL. Our results suggested an important relationship between angiogenesis and high-grade lymphoma. PMID- 29590711 TI - Position of Mandibular Condyles during Stabilization Splint Wearing. AB - The purpose of this study was to determine the position of mandibular condyles during wearing of stabilization splints with different thickness. Two stabilization splints were made for 10 completely dentate participants. First splint was made with minimal 1 mm distance at molar area between the upper and lower teeth, while the second splint was made 3 mm higher than the first splint. Condylar position measurements during splint wearing were done using ultrasound jaw tracking device with six degrees of freedom at the antero-posterior (x), vertical (y) and lateral (z) axes. Linear deviation values were calculated from the values of the Cartesian coordinate system. The mean value of linear deviation between the habitual occlusion and the occlusion with stabilization splint made at 1 mm distance in molar area was 2.04+/-1.18 mm, while with stabilization splint made 3 mm higher than the first one it was 2.32+/-1.24 mm. Independent samples T test did not confirm statistically significant difference in deviation values between the splints of different thickness. Raising stabilization splint height does not change significantly the position of the condyle within the temporomandibular joint. Higher condylar distraction in the temporomandibular joint cannot be expected with 'thicker' stabilization splint. PMID- 29590712 TI - Analysis of Airborne Dust as a Result of Plaster Cast Sawing. AB - Plaster splints are used daily in surgical and orthopedic fields in order to immobilize injured children and adults. The aim of this study was to measure the aerodynamic diameter and concentration of dust particles in the air caused by sawing plaster splints (calcium sulfate dehy-drate). We performed fractional measurements of airborne dust particles. The measured particles, which can potentially be inhaled, may have a specific negative effect on human health. Measurements were conducted in laboratory research facilities that simulated hospital conditions within a casting room and the associated waiting room. Measurements within the casting room were made using two particle collector devices and one laser photometer. The measurement for the simulated waiting room was performed using the same principles and devices. The collected plaster dust particles differed in aerodynamic diameter and concentration according to the various locations observed. The highest concentration of particles of all sizes was recorded at the site of cast sawing. There was direct correlation between distance from the source and concentration of airborne particles; this concentration was lowest in the waiting room. The concentrations of plaster dust recorded were lower than the recommended minimal limit values for total and respiratory fractions in Croatia. Accordingly, it can be assumed that sawing of plaster splints has no harmful health effects on the exposed patients and health personnel. PMID- 29590713 TI - Structure-Function Relationship of Changes in Visual Field Indices with Quadrant and Average Retinal Nerve Fiber Layer Thickness in the Eyes with Exfoliation. AB - The progressive nature of glaucoma suggests it should be possible to detect structural changes such as retinal nerve fiber layer (RNFL) thickness loss before the condition becomes clinically apparent with visual field (VF) impairment. Therefore, the aim was to analyze RNFL thickness and VF changes in study groups with unilateral exfoliation syndrome (XFS), bilateral XFS and bilateral exfoliative glaucoma (XFG), and compare it with controls. The study included 114 subjects (228 eyes) divided into 4 groups according to the presence of exfoliation: 30 subjects with unilateral XFS (30 with clinically visible XFS and 30 fellow eyes), 24 subjects (48 eyes) with bilateral XFS, 28 (56 eyes) subjects with bilateral XFG, and control group (32 subjects). All subjects underwent VF and RNFL measurements after ophthalmologic examination. Both eyes of unilateral XFS (clinically -visible and fellow eye) showed positive correlation between Mean Defect (MD) and square root of Loss of Variance (sLV) and between MD and inferior quadrant RNFL thickness. In bilateral XFS and XFG, there was negative correlation between MD and inferior quadrant RNFL thickness. Inferior, superior and nasal quadrant RNFL thickness was lower in XFG group than in other groups. In bilateral XFS group, the inferior quadrant RNFL thickness was lower as compared with unilateral XFS group (in both eyes). The mean RNFL thickness negatively correlated with MD in bilateral XFS and XFG groups. In conclusion, structural changes before VF impairment have an important role in early detection of glaucoma in subjects at risk. PMID- 29590714 TI - Manual Intracardiac Electrogram Method Is Accurate Alternative to Echocardiography for Atrioventricular and Interventricular Optimization in Cardiac Resynchronization Therapy. AB - Some manufacturers do not provide automated intracardiac electrogram method (IEGM) systems for atrioventricular (AV) and interventricular (VV) delay optimization in cardiac resynchronization therapy (CRT). We aimed to evaluate the accuracy of manual IEGM method in 48 patients previously implanted with Medtronic Syncra CRT. All patients underwent standard device interrogation followed by CRT optimization by IEGM method and by echocardiography one month after implantation. The patient mean age was 60.7+/-11.8 years and there were 33 (68.8%) males. After CRT implantation, the left ventricular ejection fraction increased from 28.0+/ 7.9% to 39.1+/-11.0% (p<0.001). Optimal aortic flow Velocity Time Integral (aVTI) was obtained when VV was set to 20-50 ms left ventricular pre-activation. There was a strong correlation between VV values determined by echocardiography and IEGM (R=0.823, p<0.001). We found no significant difference in AV, VV and aVTI values between echocardiography and IEGM method. However, IEGM was significantly less time-consuming than echocardiography [20 (10-28) vs. 40 (35-60) minutes, p<0.001]. Manual IEGM method may be good alternative to echocardiography and automated IEGM method. It also emphasizes the need for implementation of automated IEGM systems in as many CRT devices as possible. PMID- 29590715 TI - Nutritional Status and Nutrition Quality in Patients with Non-Alcoholic Fatty Liver Disease. AB - Non-alcoholic fatty liver disease (NAFLD) is becoming a major health burden with increasing prevalence worldwide due to its close association with the epidemic of obesity. Currently there is no standardized pharmacological treatment, and the only proven effective therapeutic strategy is lifestyle modification, therefore it is important to determine the potential dietary targets for the prevention and treatment of NAFLD. We assessed nutritional status in 30 patients diagnosed with NAFLD using anthropometric parameters, hand grip strength, and lifestyle and dietetic parameters (physical activity, NRS2002 form and three-day food diary). The mean body mass index was 29.62+/-4.61 kg/m2, yielding 86.67% of obese or overweight patients. Physical activity results indicat-ed poorly active subjects. Excessive energy intake was recorded in 27.78% of patients. The mean in-take of macronutrients was as follows: 15.5% of proteins, 42.3% of carbohydrates and 42.2% of fat, with -deficient micronutrient intake of calcium, magnesium, iron, zinc, and vitamins A, B1 and B2. The -results showed that the quality of nutrition in study subjects was not accordant to current rec-ommendations and that they consumed a high proportion of fat, especially saturated fatty acids, along with low micronutrient intake. The results obtained might point to the importance of unbalanced diet as a contributing factor in NAFLD development. PMID- 29590716 TI - The Role of Endothelial Dysfunction in the Mechanism of Gastroesophageal Reflux Disease Development in Patients with Ischemic Heart Disease. AB - Ischemic heart disease (IHD) and gastroesophageal reflux disease (GERD) are among the most common diseases worldwide, which in a considerable percentage of cases occur together, thus complicating symptoms, posing problems for timely diagnosis and hindering development of a comprehensive treatment regimen for both diseases. Research has shown that endothelial dysfunction is one of the major pathophysiological mechanisms in the development of IHD. Endothelial dysfunction also affects regional perfusion of the esophagus, thus compromising esophageal tissue defense mechanisms. The aim of our study was to investigate the role of endothelial dysfunction in the mechanisms of GERD development in patients with IHD. For the purpose of this study, we collected data on serum levels of endothelin-1, nitric oxide metabolites and lipid peroxidation products, gastric pH, parameters of regional blood flow, and quality of life assessment. Study results revealed that in IHD patients with concomitant GERD, endothelial dysfunction manifested by a significant increase in the levels of endothelin-1 and lipid peroxidation products, with decreased levels of nitric oxide metabolites, regional blood flow and quality of life. These findings suggest that hypoxia of the esophageal mucosa, caused by endothelial dysfunction, leads to a decrease in the esophageal tissue resistance and to esophageal lower sphincter dysfunction, which, in turn, are the leading factors in the development of GERD. PMID- 29590717 TI - A Retrospective Study of Discordant Twin Growth in Dichorionic Twin Pregnancies and Risk of Preterm Delivery at Split University Hospital Centre: Three-Year Experience. AB - The aim was to determine whether discordant twin growth has an impact on preterm birth in dichorionic pregnancies. This retrospective study included dichorionic twin pregnancies in the period from January 1, 2013 to December 31, 2015. The following variables were investigated: maternal age (years), parity, body mass index (kg/m2), week (<=366/7 and >=37) and mode of delivery (vaginal and cesarean section), birth weight (grams) and Apgar score (<=7, 8-10). Discordant twin growth in dichorionic pregnancies was found to be associated with preterm birth (chi2=4.74; p=0.03) but had no impact on the mode of delivery (chi2=0.119; p=0.73). There was a statistically significant difference in the rate of small for gestational age (SGA) neonates (chi2=16.4556; p=0.000267) and Apgar score (chi2=7.9931; p<0.05) between the study groups. Mode of conception in dichorionic pregnancies was not a risk factor for preterm delivery (chi2=1.417; p=0.23). In conclusion, discordant twin growth in dichorionic pregnancies is a risk factor for preterm delivery and has no impact on the mode of delivery but has an impact on the rate of SGA and Apgar score. PMID- 29590718 TI - Analysis of the Hemoglobin Level Drop in Patients with Hip Fracture After Admission. AB - The studies that evaluated blood loss during hip surgery found a relatively small loss that does not explain the large hemoglobin drop postoperatively. The aim of this study was to determine the fall in hemoglobin level after admission and rehydration in patients with hip fractures and to identify the patients that need blood transfusion. This retrospective study included data on 374 patients with hip fracture with surgery delayed by more than 24 hours and complete blood count repeated prior to surgery after fluid resuscitation for a minimum of 24 hours. The hemoglobin level (g/L) was analyzed after admission and after rehydration. The results were compared by Student's t-test. The mean hemoglobin drop was 6.1 g/L, 12.05 g/L and 16.52 g/L for capsular, pertrochanteric and subtrochanteric fractures, respectively. This hemoglobin drop was statistically significant in all frac-ture types. The significant drop of preoperative hemoglobin should be taken in consideration when planning transfusion for hip fracture patients. Collection of blood sample after rehydration preopera-tively would enable prompt diagnosis and treatment of anemia in these patients, along with proper transfusion planning and cross-matching. PMID- 29590719 TI - Effect of Smelling Amniotic Fluid on Comfort and Crying in Preterm Infants During Peripheral Cannulation: A Randomized Controlled Trial. AB - The aim of the study was to investigate the effect of smelling amniotic fluid on comfort and duration of crying caused by peripheral cannulation in preterm infants. This was a randomized controlled trial. The study sample consisted of 80 preterm infants meeting the case selection criteria. The infants were randomly assigned to experimental and control group. Upon exclusion of some infants from the study, total number of infants in both groups was 61. The infants in the amniotic fluid group smelled amniotic fluid for 15 minutes before, during, and for 15 minutes after the ap-plication of peripheral cannulation, whereas the infants in the control group did not undergo any in-tervention other than routine care. The level of comfort was significantly higher and the duration of crying lower in the infants from the amniotic fluid group as compared with control group before, during and after the procedure. The intervention of smelling amniotic fluid was found to be an effective practice that could be used for reducing the length of crying and increase comfort in preterm infants undergoing peripheral cannulation. PMID- 29590720 TI - Implementation of Venous Thromboembolism Prophylaxis Guidelines in Clinical Practice: A Retrospective Study in Two Croatian Hospitals. AB - The aim of this study was to evaluate the implementation of the 9th edition of the American College of Chest Physicians (ACCP9) guidelines for prevention of venous thromboembolism in nonsurgical patients in clinical practice in one university and one general Croatian hospital. A retrospective study was conducted at Zadar General Hospital from Zadar and Dubrava University Hospital from Zagreb. Medical charts of all patients admitted to Medical Departments in two periods, before and after implementation of the ACCP9 guidelines, were analyzed. The ACCP9 guidelines were made available to all physicians through the hospital electronic information system immediately after the publication. The Hospital Drug Committees promoted implementation of the guidelines during their periodical clinical visits. Overall, 850 patients were included in the study in two periods. There was no statistically significant difference in the number of high-risk patients receiving thromboprophylaxis after the guidelines implementation in either hospital. In both periods, a signifi-cantly higher number of high-risk patients received thromboprophylaxis in Dubrava University Hos-pital in comparison with Zadar General Hospital (31.7% vs. 3.8% and 40.3% vs. 7.3%, respectively; p<0.001). This study revealed insufficient implementation of evidence-based thromboprophylaxis guidelines in clinical practice in two Croatian hospitals. PMID- 29590721 TI - Chemerin Blood Levels are Associated with MRI Measured Volumes of Abdominal Adipose Tissue Compartments and Lifestyle Choices. AB - Obesity is a low-grade chronic inflammatory state, in which a cytokine chemerin with its immunometabolic modulation has an important role. We aimed to study in a healthy population relationships between serum chemerin levels, lifestyle choices and magnetic resonance imaging (MRI) assessed volumes of abdominal visceral (VAT) and subcutaneous (SAT) adipose tissues, which have different cytokine expression profiles. Overall, 73 healthy participants undertook lifestyle questionnaire and underwent anthropometric measurements along with MRI scanning of abdominal SAT and VAT. Furthermore, complete blood count was determined along with chemerin and fibrinogen serum levels. Regression model for prediction of chemerin serum levels was built after controlling for sex, age and anthropometric measures. Median serum chemerin was 141 (125-195) ng/mL. Serum chemerin had a moderate positive correlation with SAT and VAT volumes. The two most important predictors of chemerin levels were MRI detected SAT and thigh circumference. Independently, chemerin levels were associated with smoking, preference of salty food, and favoring flavor/simplicity of preparation over nutritional value of the food. Serum chemerin seems to be more strongly correlated with the volume of abdominal SAT than VAT, with certain lifestyle choices influencing chemerin levels independently of abdominal fat. PMID- 29590722 TI - Association of Pentraxin-3, Galectin-3 and Matrix Metalloproteinase-9/Timp-1 with Cardiovascular Risk in Renal Disease Patients. AB - Inflammation, apoptosis and extracellular remodeling play significant roles in cardiovascular disease (CVD) underlying the major causes of mortality in renal patients. In 19 pre-dialysis patients, 21 dialysis patients and 20 control subjects, the concentrations of pentraxin-3, galectin-3, MMP-9 and TIMP-1 were determined by ELISA. CVD risk was calculated according to the Framingham risk score algorithm. Pentraxin-3 was increased in renal patients compared to healthy controls (p<0.001). In contrast, galectin-3 was reduced in hemodialysis patients compared to pre-dialysis patients and controls (p<0.001). In addition, MMP-9 and TIMP-1 were elevated in renal patients compared to controls (p<0.01 and p<0.001, respectively). Logistic regression analyses disclosed associations of galectin-3, MMP-9, pentraxin-3 and glomerular filtration with calculated CVD risk score. Combined testing of pentraxin-3, galectin-3, MMP-9 and glomerular filtration rate can discriminate renal patients with high and low risk of a coronary event. PMID- 29590723 TI - Business Performance of Health Spa Tourism Providers in Relation to the Structure of Employees in the Republic of Croatia. AB - Health spa tourism services are provided in special hospitals for medical rehabilitation and health resorts, and include controlled use of natural healing factors and physical therapy under medical supervision in order to improve and preserve health. Health tourism is a service industry and therefore labor intensive industry in which human resources are one of the key factors of business success. The aim of this study was to analyze business performance of special hospitals for medical rehabilitation and health resorts in Croatia in relation to the structure of employees, specifically the number of physicians and total medical personnel, as well as the share of physicians and medical personnel in the total number of employees. The assumption was that those who employ more physicians and medical employees are more successful. The empirical research was conducted and the assumption was tested firstly by correlation analysis and afterwards by regression analysis. The total number of employees in the researched health resorts and special hospitals amounted to 2,863, of which the share of physicians specialists accounted for almost 7%, while the share of total medical staff was almost 53%. From the results of our research, it can be concluded that special hospitals for medical rehabilitation and health resorts, which employ more physicians and medical personnel, are achieving better financial business performance. Based on the results obtained, it is possible to provide guidance for further growth and development in the direction of basing the primary offer on medical-health offer, rather than on wellness offer, which is a strong trend in the world. These findings are important for planning the health and tourism policies in Croatia and similar countries. PMID- 29590724 TI - Comparing Diagnostic Accuracy of Direct Questioning Versus Schematic Evaluation of Chronic Pain Localization. AB - None of the previous studies localized pain in comparison with graphic scheme. Our aim was to investigate the validity of direct questioning about the main pain localization in comparison with schematic evaluation. In this cross-sectional study, 331 patients, mean age 49.4+/-10.72 years, localized their main pain site anatomically with manikin and by direct questioning. Two methods were employed to localize pain: direct questioning and schematic evaluation (manikin). Sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and odds ratio (OR) were used to compare these two methods. Study patients answered in both methods. The sensitivity and PPV were mostly in a weak range, while accuracy, specificity and NPV were mostly in good range. Kappa index was in the marginal reproducibility range. Pain in the left part of the body had a higher OR (OR=9). PLR for pain in the right part of the body was 28.03. NLR for all questions was located in the small and rarely important change probability group. Negative answer in direct questioning was more reliable than a positive one. Pain localization in the left side of the body was more reliable. PMID- 29590725 TI - Nutritional Issues and Nutrition Support in Older Home Care Patients in the City of Zagreb. AB - Population aging is a global demographic trend showing continuous growth and among its consequences is a rise in malnutrition that is characteristic for the elderly. The objective of this study was to evaluate nutritional status of elderly home care patients immediately after hospital discharge and to determine factors that affect nutritional status using questionnaires based on validated tools (NRS-2002, DETERMINE checklist) and basic medical history data. The study involved 76 elderly individuals (51.3% of them older than 70) living in the City of Zagreb. The nutritional status assessment using the NRS-2002 tool showed that 57.6% of the subjects were at nutritional risk. The findings of the assessment by use of the DETERMINE tool were also unfavorable, indicating that 82.1% of persons older than 70 were categorized as being at a high nutritional risk, while 17.9% were at moderate risk. The DETERMINE checklist elements (illness; reduced intake of fruits, vegetables or dairy products; alcohol consumption; oral health problems; and weight loss) were linked to a higher NRS score. The mean number of hospital days in subjects at nutritional risk was 14.27 (the mean number in the Republic of Croatia is 8.56 days). Although the study involved a small number of subjects, the results showed a substantial presence of malnutrition among the elderly. A timely -intervention by the healthcare system and training of healthcare personnel can be a step towards achieving a better nutritional status. PMID- 29590726 TI - Bleeding Peptic Ulcer - Tertiary Center Experience: Epidemiology, Treatment and Prognosis. AB - The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality. PMID- 29590727 TI - Nonverbal Memory Capacity in Persons with Epilepsy Is Associated with Depression Rather than Anxiety. AB - Epilepsy is characterized by repeated epileptic seizures, which are manifested in various ways and depend on the location and size of foci in the brain. Long-term seizures with secondary generalization can cause memory problems. Numerous studies demonstrate the connection of memory damage and lateralization in medial temporal lobe epilepsy (TLE). However, the results were not always consistent with the material-specific memory model. A possible explanation for these inconsistent data is the insufficient control of psychological variables that can affect memory. In most of the previous studies in persons with epilepsy, they were not controlled for their emotional states such as anxiety and depression. We used the Rey Complex Figure Test (RCFT) as a measure of visual memory, Beck's depression inventory as a measure of depressive symptoms, and the State-Trait Anxiety Inventory as a measure of anxiety in 57 consecutive participants. Our aim was to investigate whether there is difference in visual memory with respect to the left and right TLE, and whether the participants of different gender with higher anxiety and depression rates would achieve different results on visual memory. Persons with lower levels of depression achieved better scores in the Immediate and Delayed recall subtests of the RCFT. We also explored the potential gender differences. Testing differences between the persons with higher and lower anxiety levels did not reveal any significant differences in any of the measures tested. PMID- 29590728 TI - Diabetic Polyneuropathy and Risk of Falls: Fear of Falling and Other Factors. AB - The aim of the study was to analyze postural stability, walking speed and fear of falling in patients with diabetic polyneuropathy (DPN) in order to determine the risk factors for falls, as well as the effect of DPN characteristics as additional factors. A sample of 48 patients with type 2 diabetes and DPN were enrolled in this non-randomized observational study. The patients were divided into two groups of fallers and non-fallers. All subjects underwent evaluation with the Functional Reach Test (FRT), Tinetti Falls Efficacy Scale (Tinetti FES) and 10-Meter Walk Test (10MWT). Neuropathy was quantified with the Michigan Neuropathy Screening Instrument (MNSI, Questionnaire part) and 5.07/10-g Semmes Weinstein monofilament examination (SW-ME). The 10MWT and SW-ME were significantly different between the faller and non-faller groups (p<0.05). Duration of DPN correlated positively with SW-ME (p=0.005) in the faller group. FES showed significant positive correlation with MNSI and negative correlation with 10MWT in the non-faller group. Logistic regression analysis revealed that SW ME was significantly associated with the probability of falling (p=0.0076; OR=1.378). Study results suggested that the loss of protective sensitivity of foot could be a risk factor for falls in people suffering from type 2 diabetes. PMID- 29590729 TI - Determination of Predictive Anatomic Parameters for Bleeding of Brain Arteriovenous Malformations by Multidetector CT Angiography. AB - Patients with brain arteriovenous malformation (AVM) have a certain risk to bleed, and the goal of this study was to examine the effect of radiological and clinical predictive characteristics of AVM hemorrhage using multidetector computed tomographic (MDCT) angiography. The study included a series of 57 patients, mean age 35.46 years, who were diagnosed during their hospitalization at Clinical Department of Neurosurgery, Clinical Center of Serbia, in the period from January 2008 to March 2016. In all patients, the diagnosis was made using MDCT angiography. Two groups of patients were observed. The first group included patients who did not initially present with hemorrhage, while the second group initially presented with hemorrhage. Both groups were treated with medical therapy or a combination of medical therapy with embolization/surgery/radiotherapy. Deep venous drainage (p<0.05), combined arterial supply from different basins (p<0.05) with a length <60 mm, venous dilatation present in the drainage vein (p<0.01), and the angle of casting sup ply arteries in the nidus (p<0.01) carry a risk of repeated bleeding. In the group of patients who had initial hemorrhage, the mean value of the casting angle size was 130 degrees , while in the group that did not have initial bleeding the mean value of the measured angle size was 103.81 degrees with standard deviation of 17.21 degrees (p<0.01). In conclusion, AVMs with deep venous drainage from the carotid and vertebrobasilar basin, the length of the feeding arteries <60 mm, the angle of the casting feeding arteries in the nidus >=130 degrees and dilatation and/or venous aneurysm of drainage vessel are predictive for clinical presenting by hemorrhage. PMID- 29590730 TI - Serum Osteoprotegerin in Patients with Calcified Aortic Valve Stenosis in Relation to Heart Failure. AB - The aim of the study was to assess the role of serum osteoprotegerin (OPG) as a biomarker in patients with aortic valve stenosis (AS) in relation to heart failure and symptomatic status. This was a case control study, which included 51 patients with AS and 39 control subjects. At the time of study enrolment, detailed medical history was obtained and all subjects underwent physical examination, chest x-ray and echocardiography. OPG levels were measured in all subjects, and serum N-terminal of the pro b-type natriuretic peptide (NT pro BNP) levels were determined in patients with AS. Serum OPG levels were elevated in patients with AS compared to control subjects (p=0.001). Patients with heart failure due to AS had elevated serum OPG levels in comparison to patients without heart failure (p=0.001). A significant correlation between OPG and symptomatic status was observed in all patients with AS (p<0.001), however, it was not the case in patients without heart failure (p=0.425). There was a positive correlation between OPG and NT pro BNP concentrations with objective signs of heart failure on chest x-ray (p<0.001). Negative correlation of OPG concentrations with aortic valve area was present (p<0.040), as well as with left ventricular ejection fraction (p<0.001). Serum OPG could be a valuable biomarker in the evaluation of severity of calcified AS and serve as an additional indicator besides clinical presentation and echocardiography in the assessment of surgical treatment or aortic valve replacement. PMID- 29590731 TI - Parental Socioeconomic Status as a Predictor of Physical and Mental Health Outcomes in Children - Literature Review. AB - Parental socioeconomic status is a multidimensional concept of special importance for the growth, development, health outcomes and education of children. Its definition generally refers to the amount of parents' income, their employment status and level of education. Hence, lack of economic resources and poverty of parents affect all aspects of the child's life, health outcomes and education, as well as his/her social inclusion. Accordingly, the consequences of a reduced parental socioeconomic status leave long-term effects on their children. Therefore, in order to create interventional programs for children of parents with low income and lower socioeconomic status, as well as with lower level of education, it is important to address the direct aspects of poverty. This review contributes to the evidence indicating that the parental socioeconomic status is highly influential in determining the child's physical and mental health and future outcomes including his/her academic achievements and education, as well as the parameters of his/her physical abilities, cognitive function and fundamental neurobiology affecting brain development. PMID- 29590732 TI - Genetic Aspects of Hereditary Arrhythmogenic Syndromes in Children and Adults. AB - Recent research has revealed the genetic etiology of a number of heart diseases that cause sudden cardiac death. Lethal channelopathies are of great importance among the genetically determined heart diseases. Their basic characteristics are unpredictable and deadly nature, autosomal dominant inheritance with variable expressivity and incomplete penetrance in structurally normal heart, and absence of morphological and histological clues that a standard autopsy can identify. Minimum screening of the relatives of sudden cardiac death victims involves taking medical history, physical examination, electrocardiography, echocardiography, and exercise testing. Total positivity of classic genetic tests is only 15%-25%. Even the next generation sequencing technology does not provide a positive result of genetic testing in more than 35% of cases. Therefore, it is necessary to identify a larger number of genes the presence of which can lead to sudden cardiac death, to reduce the number of false positive results, and point to the importance of conducting genetic testing of young victims of sudden cardiac death. Until then, it is enough to preserve 5 g of fresh heart tissue of sudden cardiac death victims at a temperature of -80 degrees C. The material can be analyzed years later without losing its actuality because it contains information important for the next generation of the sudden cardiac death victim relatives.

AB - Ocular vestibular evoked myogenic potentials (oVEMP) and cervical VEMP (cVEMP) are newer diagnostic methods, which allow an insight into the otolith senses. Our aim was to determine changes in certain parameters of the VEMP wave complex after successfully performed repositioning procedure, as an indicator of the state of recovery in patients with benign paroxysmal positional vertigo (BPPV). This may confirm the theory of otolith returning into the area of otolithic senses. The study included 48 patients with unilateral posterior semicircular canal BPPV. On their first arrival, otoneurological examinations, oVEMP and cVEMP tests were performed. The same were included in follow up check-ups scheduled at seven days and six months after successful implementation of Epley maneuvers. The initial measurement revealed a significantly reduced amplitude of oVEMP on the affected side. On the 7-day measurement, the amplitude increase was observed on the affected side, with significant reduction in the amplitude ratio (p=0.693), which reached statistical significance on the last measurement at 6 months (p=0.006). These findings confirmed the hypothesis of the return of otoconia into the utricular area.

PMID- 29590735 TI - Umbilical Cord Management and Stump Care in Normal Childbirth in Slovenian and Croatian Maternity Hospitals. AB - The aim was to investigate first-care procedures for the newborn's umbilical cord at maternity hospitals in Slovenia and Croatia. The study was based on an empirical survey research approach and quantitative research paradigms and included all Slovenian (n=14) and all Croatian (n=35) maternity hospitals. Leaders of midwifery team of 14 Slovenian and 35 Croatian labor wards were invited to participate. The study was conducted in 2013, with 67% of Slovenian and 66% of Croatian maternity hospitals having responded. A causal and non experimental method of empirical research was used. The research instrument was a questionnaire. Descriptive statistics was used on data analysis. The independence hypothesis was tested with the chi2-test or Kullback 2I-test. A vast ma-jority of study wards employed delayed umbilical cord clamping, i.e. clamping the cord after pulsa-tion had ceased. Only 10% of Slovenian in comparison with 36.4% of Croatian maternity hospitals practiced dry cord care. Others applied disinfectant on the cord, in Slovenia most frequently 6% po-tassium permanganate, and in Croatia a combination of octenidine and phenoxyethanol. Most Croa-tian -maternity wards (95.7%) still covered the stump, while it was not regular practice in Slovenia. The authors estimate that the prevailing Slovenian and Croatian practices in regard to cord clamping are in accordance with the evidence, while improvements could be made regarding stump care, since dry cord care is the recommended method. PMID- 29590736 TI - Incidence of Central Nervous System Tumors in Patients Hospitalized at Split University Hospital Centre During a Ten-Year Period (January 1, 2004 - December 31, 2013). AB - The aim was to evaluate the incidence and characteristics of central nervous system tumors in patients hospitalized at the Department of Neurology, Split University Hospital Centre, during a 10-year period. The study included data on 859 patients with the diagnosis of central nervous system (CNS) tumor. Diagnosis was based on the routine CNS neuroimaging methods (computed tomography/magnetic resonance imaging). Access to patient medical records provided demographic and clinical data, continued by collection of data on potential lethal outcome of patients at the Registrar's Office. The study was conducted at the Department of Neurology, Split University Hospital Centre, from January 1, 2004 to December 31, 2013. There were 448 male and 411 female patients. Median age at the diagnosis was 65 (range, 18-95) years. Primary CNS tumors were diagnosed in 527 patients, including 30 primary recurrent tumors, whereas 328 patients had metastatic tumors; in 4 cases, it was impossible to determine whether the tumor was a primary one or metastasis based on CNS neuroimaging. The primary tumors proved to be more common than the metastatic ones (chi2-test, p<0.05). Multiple tumor transplants were more common than solitary (211 vs. 117; the conclusion was made at a 95% level of confidence; chi2-test, p<0.05). The majority of metastases originated from the lung (bronchus and pleura cancer; 46.41%; chi2-test, p<0.05; 95% CI). The most common localization of CNS tumors was supratentorial. Based on the double-logarithmic model, we proved with statistical significance that there was an increase in the incidence of CNS tumors (p=0.001). The most common tumors studied were supratentorially localized meningiomas. PMID- 29590737 TI - Prevalence of Open Angle Glaucoma in Risk Groups in Slavonia and Baranya Region. AB - The aim of this prospective study was to detect primary open angle glaucoma (POAG) in its early stage in patients at a higher risk of its development, and to identify the risk group with the highest prevalence of POAG. The study was conducted at Department of Ophthalmology, Osijek University Hospital Centre, and included 250 patients divided into five groups, as follows: group 1, patients with diabetes type 1 and type 2; group 2, patients with arterial hypertension (blood pressure >140/90 mm Hg); group 3, patients with positive family history of POAG; group 4, patients with myopia between -3.0 and -8.0 diopters; and group 5, control group including patients aged 40 with no risk factors for POAG development. Study results showed that distribution of glaucoma patients was not equal across the groups. The prevalence of POAG in all patients was 5.6%, whereas in patients with positive family history of POAG it was 14%, which was statistically significantly higher than in patients with diabetes and myopia (4% both), as well as in control group. The difference was greatest in comparison to control group. There was no statistically significant difference in glaucoma incidence between the group of patients with positive family history (14%) and patients with systemic hypertension (6%). The results obtained suggest that of all risk factors analyzed, positive family history of POAG is the most important risk factor for glaucoma development in all risk groups. PMID- 29590738 TI - Effect of the Size of the Left Atrium on Sustained Sinus Rhythm in Patients Undergoing Mitral Valve Surgery and Concomitant Bipolar Radiofrequency Ablation for Atrial Fibrillation. AB - Atrial fibrillation is associated with systemic embolization and complications due to anticoagulant therapy. Radiofrequency ablation has been established as an effective and safe method for the treatment of atrial fibrillation. The aim of this study was to evaluate the effect of the size of the left atrium on the outcome of surgical radiofrequency ablation. Forty patients scheduled for elective mitral valve surgery and radiofrequency ablation were enrolled in the study. Group 1 consisted of patients with a left atrium diameter <=5 cm and group 2 of patients with left atrium diameter >5 cm. The primary endpoint of the study was stable sinus rhythm 6 months postoperatively. At 6 months postoperatively, sinus rhythm was present in significantly more group 1 patients as compared with group 2 patients, i.e. 15 (75%) vs. 8 (40%), p=0.025. Multivariate analysis proved the size of the left atrium to be an independent predictor of the radiofrequency ablation outcome. Accordingly, the size of the left atrium was demonstrated to be an important predictor of the outcome of radiofrequency ablation for atrial fibrillation. A lower cut-off value of surgical reduction of the atria than previously reported should be considered in order to improve the radiofrequency ablation outcome. PMID- 29590739 TI - Gastrostomy Under Paravertebral Block in High-Risk Patients with Esophageal Cancer - Two Case Reports. AB - Here we present two cases of gastrostomy insertion via laparotomy in patients with malignant esophageal disease. Patients were ASA (American Society of Anesthesiologists) physical status III and IV. The patients presented as very high risk for general anesthesia, so we decided to use unilateral left sided paravertebral block (PVB) on four thoracic levels along with contralateral local infiltration at the gastrostomy insertion site. We present two cases, one of them a 57-year-old male ASA III patient scheduled for a gastrostomy procedure due to esophageal cancer with infiltration of the trachea. We also present a case of a 59-year-old male patient, ASA IV status, scheduled for the same procedure due to advanced esophageal cancer with a fistula between the left main bronchus and the esophagus and metastases in the left lung. The paravertebral space was identified with the use of an 8 Hertz (Hz) linear ultrasound probe and a nerve stimulator. Paravertebral block was successfully used for insertion of a gastrostomy, thereby enabling adequate anesthesia and perioperative analgesia without hemodynamic or respiratory complications. PMID- 29590740 TI - Uniportal Video-Assisted Thoracic Surgery for Pulmonary Hamartoma: Case Report. AB - Pulmonary hamartoma is the most common benign tumor of the lung. It accounts for 77% of all benign lung tumors but less than 1% of all lung tumors. Malignant alteration is -extremely rare. Surgical removal is therapy of choice. Uniportal video-assisted thoracic surgery is an easy-to-learn variant of video-assisted thoracic surgery. The approach is very similar to classic thoracotomy. Instruments for both classic and video-assisted thoracic surgery can be combined. A case is presented of a 44-year-old female patient with pulmonary hamartoma treated by uniportal video-assisted -thoracic surgery as a new method used for the first time at our department. PMID- 29590741 TI - Relapse of Pleomorphic Adenoma from Childhood to Adulthood: Case Report. AB - Pleomorphic adenoma is rarely seen in childhood. After detailed literature search, we did not come across a case of frequent relapse of this benign tumor from childhood to adulthood. The World Health Organization defines relapse of pleomorphic adenoma as a histologically benign tumor that can have local or distant metastasis. There is one hypothesis how benign tumor can metastasize. According to this hypothesis, probably during the first operative procedure the tissue around the tumor becomes permeable for tumor cells, which can lead to implantation of tumor cells into the surrounding tissue. In this case report, we present a case of a 30-year-old woman with pleomorphic adenoma of the submandibular gland, which relapsed three times. The patient was first operated on in 1993, at the age of 7 years. The first two relapses occurred in 1998 and 2001, at the age of 12 and 15, respectively. The last relapse occurred in 2015, at the age of 29 years. All relapses were localized in the submandibular region on the right side of the neck, where the primary tumor had been operated on.

AB - Myasthenia gravis is associated in 10 to 15 percent of patients with thymic tumors, rarely with aplastic anemia. We report a 45-year-old male diagnosed with myasthenia gravis associated with thymoma. We started treatment with pyridostigmine. After thymectomy, the patient received 30 irradiation sessions. In the postoperative course, he had mild worsening of myasthenia gravis, which improved with prednisone. Five months later, he developed severe aplastic anemia. He was dependent on blood supplement. After allogeneic transplantation of bone marrow, he improved but later he -developed graft versus host disease. Myasthenia gravis was under good control with 480 mg of pyridostigmine per day.

AB - We evaluated the effect of silicone stent use during endoscopic dacryocystorhinostomy on postoperative morbidities in comparison with versus without a silicone stent. Two authors independently searched six databases (PubMed, Embase, Scopus, the Web of Science, the Cochrane library, and Google Scholar) from inception of article collection to July 2017. The analysis included prospective randomized studies that compared intraoperative silicone stent insertion (silicone group) with no application of a silicone stent (control group), in which the outcomes of interest were success rate (lacrimal passage patent check with syringing, symptom relief, or endoscopic confirmation of fluorescein dye from the opening of Hasner's valve) and morbidities (e.g., postoperative bleeding, rhinostomy closure, granulation tissue, synechia, and eyelid problems) after certain follow-up periods (over 10 weeks). Nine studies involving a total of 587 participants were included. Functional success rates tended to be higher in the silicone group than in the control, but there was no statistically significant difference in success rates (odds ratio, 1.45; 95% confidence interval, 0.77 to 2.73). According to the surgical type such as mucosal removal and mucosal flap surgery, the results from types didn't demonstrate any significant effect, but the mucosal flap technique seemed to be more beneficial. Regarding postoperative morbidities, although the outcomes of the groups did not present any statistically significant difference, eyelid problems and postoperative bleeding tended to occur more frequently in the silicone group, but rhinostomy closure tended to occur more frequently in the control group. Success and morbidity rates showed no difference between the silicone stent group and control group in the meta-analysis. However, additional analyses revealed that the success rate of endonasal dacryocystorhinostomy using silicone intubation with mucosal flap has shown an improving trend, and morbidities such as granulation and synechia showed decreasing trends compared with the group without silicone intubation. PMID- 29590745 TI - High-Frequency Stimulation of the Subthalamic Nucleus Activates Motor Cortex Pyramidal Tract Neurons by a Process Involving Local Glutamate, GABA and Dopamine Receptors in Hemi-Parkinsonian Rats. AB - Deep brain stimulation (DBS) is widely used to treat advanced Parkinson's disease (PD).Here, we investigated how DBS applied on the subthalamic nucleus (STN) influenced the neuralactivity in the motor cortex. Rats, which had the midbrain dopaminergic neurons partially depletedunilaterally, called the hemi-Parkinsonian rats, were used as a study model. c-Fos expression in theneurons was used as an indicator of neural activity. Application of high-frequency stimulation (HFS)upon the STN was used to mimic the DBS treatment. The motor cortices in the two hemispheres ofhemi-Parkinsonian rats were found to contain unequal densities of c Fos-positive (Fos+) cells, andSTN-HFS rectified this bilateral imbalance. In addition, STN-HFS led to the intense c-Fos expressionin a group of motor cortical neurons which exhibited biochemical and anatomical characteristicsresembling those of the pyramidal tract (PT) neurons sending efferent projections to the STN. Thenumber of PT neurons expressing high levels of c-Fos was significantly reduced by local applicationof the antagonists of non-N-methyl-D-aspartate (non NMDA) glutamate receptors, gammaaminobutyricacid A (GABAA) receptors and dopamine receptors in the upper layers of the motorcortex. The results indicate that the coincident activations of synapses and dopamine receptors inthe motor cortex during STN-HFS trigger the intense expression of c-Fos of the PT neurons. Theimplications of the results on the cellular mechanism underlying the therapeutic effects of STN-DBSon the movement disorders of PD are also discussed. PMID- 29590746 TI - Utility of BRAF VE1 Immunohistochemistry as a Screening Tool for Colorectal Cancer Harboring BRAF V600E Mutation. AB - BACKGROUND: BRAF mutation has been recognized as an important biomarker of colorectal cancer (CRC) for targeted therapy and prognosis prediction. However, sequencing for every CRC case is not cost-effective. An antibody specific for BRAF V600E mutant protein has been introduced, and we thus examined the utility of BRAF VE1 immunohistochemistry for evaluating BRAF mutations in CRC. METHODS: Fifty-one BRAF-mutated CRCs and 100 age and sexmatched BRAF wild-type CRCs between 2005 and 2015 were selected from the archives of Asan Medical Center. Tissue microarrays were constructed and stained with BRAF VE1 antibody. RESULTS: Forty-nine of the 51 BRAF-mutant CRCs (96.1%) showed more than moderate cytoplasmic staining, except for two weakly stained cases. Six of 100 BRAF wild type cases also stained positive with BRAF VE1 antibody; four stained weakly and two stained moderately. Normal colonic crypts showed nonspecific weak staining, and a few CRC cases exhibited moderate nuclear reactivity (3 BRAF-mutant and 10 BRAF wild-type cases). BRAF-mutated CRC patients had higher pathologic stages and worse survival than BRAF wild-type patients. CONCLUSIONS: BRAF VE1 immunohistochemistry showed high sensitivity and specificity, but occasional nonspecific staining in tumor cell nuclei and normal colonic crypts may limit their routine clinical use. Thus, BRAF VE1 immunohistochemistry may be a useful screening tool for BRAF V600E mutation in CRCs, provided that additional sequencing studies can be done to confirm the mutation in BRAF VE1 antibody positive cases.

PMID- 29590748 TI - Interfacial Mechanophore Activation Using Laser-Induced Stress Waves. AB - A new methodology is developed to activate and characterize mechanochemical transformations at a solid interface. Maleimide-anthracene mechanophores covalently anchored at a fused silica-polymer interface are activated using laser induced stress waves. Spallation-induced mechanophore activation is observed above a threshold activation stress of 149 MPa. The retro [4+2] cycloaddition reaction is confirmed by fluorescence microscopy, XPS, and ToF-SIMS measurements. Control experiments with specimens in which the mechanophore is not covalently attached to the polymer layer exhibit no activation. In contrast to activation in solution or bulk polymers, whereby a proportional increase in mechanophore activity is observed with applied stress, interfacial activation occurs collectively with spallation of the polymer film.

AB - Transient receptor potential ankyrin 1 (TRPA1) is a non-selective cation channel expressed in sensory neurons where it functions as an irritant sensor for a plethora of electrophilic compounds and is implicated in pain, itch, and respiratory disease. To study its function in various disease contexts, we sought to identify novel, potent, and selective small-molecule TRPA1 antagonists. Herein we describe the evolution of an N-isopropylglycine sulfonamide lead (1) to a novel and potent (4 R,5 S)-4-fluoro-5-methylproline sulfonamide series of inhibitors. Molecular modeling was utilized to derive low-energy three dimensional conformations to guide ligand design. This effort led to compound 20, which possessed a balanced combination of potency and metabolic stability but poor solubility that ultimately limited in vivo exposure. To improve solubility and in vivo exposure, we developed methylene phosphate prodrug 22, which demonstrated superior oral exposure and robust in vivo target engagement in a rat model of AITC-induced pain. PMID- 29590750 TI - Repurposing a Library of Human Cathepsin L Ligands: Identification of Macrocyclic Lactams as Potent Rhodesain and Trypanosoma brucei Inhibitors. AB - Rhodesain (RD) is a parasitic, human cathepsin L (hCatL) like cysteine protease produced by Trypanosoma brucei ( T. b.) species and a potential drug target for the treatment of human African trypanosomiasis (HAT). A library of hCatL inhibitors was screened, and macrocyclic lactams were identified as potent RD inhibitors ( Ki < 10 nM), preventing the cell-growth of Trypanosoma brucei rhodesiense (IC50 < 400 nM). SARs addressing the S2 and S3 pockets of RD were established. Three cocrystal structures with RD revealed a noncovalent binding mode of this ligand class due to oxidation of the catalytic Cys25 to a sulfenic acid (Cys-SOH) during crystallization. The P-glycoprotein efflux ratio was measured and the in vivo brain penetration in rats determined. When tested in vivo in acute HAT model, the compounds permitted up to 16.25 (vs 13.0 for untreated controls) mean days of survival. PMID- 29590751 TI - 2 H-1,2,3-Triazole-Based Dipeptidyl Nitriles: Potent, Selective, and Trypanocidal Rhodesain Inhibitors by Structure-Based Design. AB - Macrocyclic inhibitors of rhodesain (RD), a parasitic cysteine protease and drug target for the treatment of human African trypanosomiasis, have shown low metabolic stability at the macrocyclic ether bridge. A series of acyclic dipeptidyl nitriles was developed using structure-based design (PDB ID: 6EX8 ). The selectivity against the closely related cysteine protease human cathepsin L (hCatL) was substantially improved, up to 507-fold. In the S2 pocket, 3,4 dichlorophenylalanine residues provided high trypanocidal activities. In the S3 pocket, aromatic residues provided enhanced selectivity against hCatL. RD inhibition ( Ki values) and in vitro cell-growth of Trypanosoma brucei rhodesiense (IC50 values) were measured in the nanomolar range. Triazole-based ligands, obtained by a safe, gram-scale flow production of ethyl 1 H-1,2,3 triazole-4-carboxylate, showed excellent metabolic stability in human liver microsomes and in vivo half-lives of up to 1.53 h in mice. When orally administered to infected mice, parasitaemia was reduced but without complete removal of the parasites. PMID- 29590752 TI - Total Synthesis of Tiacumicin A. Total Synthesis, Relay Synthesis, and Degradation Studies of Fidaxomicin (Tiacumicin B, Lipiarmycin A3).

Salient features of this synthesis include a beta-selective noviosylation, a beta-selective rhamnosylation, a ring-closing metathesis, a Suzuki coupling, and a vinylogous Mukaiyama aldol reaction. Careful choice of protecting groups and fine-tuning of the glycosylation reactions led to the first total synthesis of fidaxomicin. In addition, a relay synthesis of fidaxomicin was established, which gives access to a conveniently protected intermediate from the natural material for derivatization. The first total synthesis of a related congener, tiacumicin A, is presented. PMID- 29590753 TI - Detachment of Rough Colloids from Liquid-Liquid Interfaces. AB - Particle surface roughness and chemistry play a pivotal role in the design of new particle-based materials. Although the adsorption of rough particles has been studied in the literature, desorption of such particles remains poorly understood. In this work, we specifically focus on the detachment of rough and chemically modified raspberry-like microparticles from water/oil interfaces using colloidal-probe atomic force microscopy. We observe different contact-line dynamics occurring upon particle detachment (pinning vs sliding), depending on both the particle roughness and surface modification. In general, surface roughness leads to a reduction of the desorption force of hydrophobic particles into the oil and provides a multitude of pinning points that can be accessed by applying different loads. Our results hence suggest future strategies for stabilization and destabilization of Pickering emulsions and foams.

AB - We demonstrate the rational design and construction of sandwich-like ZnIn2S4 In2O3 hierarchical tubular heterostructures by growing ZnIn2S4 nanosheets on both inner and outer surfaces of In2O3 microtubes as photocatalysts for efficient CO2 photoreduction. The unique design integrates In2O3 and ZnIn2S4 into hierarchical one-dimensional (1D) open architectures with double-heterojunction shells and ultrathin two-dimensional (2D) nanosheet subunits. This design accelerates the separation and transfer of photogenerated charges, offers large surface area for CO2 adsorption, and exposes abundant active sites for surface catalysis. Benefiting from the structural and compositional merits, the optimized ZnIn2S4 In2O3 photocatalyst exhibits outstanding performance for reductive CO2 deoxygenation with considerable CO generation rate (3075 MUmol h-1 g-1) and high stability. PMID- 29590755 TI - Bioinspired Star-Shaped Poly(l-lysine) Polypeptides: Efficient Polymeric Nanocarriers for the Delivery of DNA to Mesenchymal Stem Cells. AB - The field of tissue engineering is increasingly recognizing that gene therapy can be employed for modulating in vivo cellular response thereby guiding tissue regeneration. However, the field lacks a versatile and biocompatible gene delivery platform capable of efficiently delivering transgenes to mesenchymal stem cells (MSCs), a cell type often refractory to transfection. Herein, we describe the extensive and systematic exploration of three architectural variations of star-shaped poly(l-lysine) polypeptide (star-PLL) with varying number and length of poly(l-lysine) arms as potential nonviral gene delivery vectors for MSCs. We demonstrate that star-PLL vectors are capable of self assembling with pDNA to form stable, cationic nanomedicines. Utilizing high content screening, live cell imaging, and mechanistic uptake studies we confirm the intracellular delivery of pDNA by star-PLLs to MSCs is a rapid process, which likely proceeds via a clathrin-independent mechanism. We identify a star-PLL composition with 64 poly(l-lysine) arms and five l-lysine subunits per arm as a particularly efficient vector that is capable of delivering both reporter genes and the therapeutic transgenes bone morphogenetic protein-2 and vascular endothelial growth factor to MSCs. This composition facilitated a 1000-fold increase in transgene expression in MSCs compared to its linear analogue, linear poly(l-lysine). Furthermore, it demonstrated comparable transgene expression to the widely used vector polyethylenimine using a lower pDNA dose with significantly less cytotoxicity. Overall, this study illustrates the ability of the star-PLL vectors to facilitate efficient, nontoxic nucleic acid delivery to MSCs thereby functioning as an innovative nanomedicine platform for tissue engineering applications. PMID- 29590756 TI - Improved Outcomes With Integrated Intensivist Consultation for Cardiac Surgery Patients. AB - This study examined the impact of integrated intensivist consultation in the immediate postoperative period on outcomes for cardiac surgery patients. A retrospective cohort study was conducted in 1711 adult cardiac surgery patients from a single quaternary care center in Minnesota. Outcomes were compared across 2 consecutive 2-year time periods reflecting an elective intensivist model (n = 801) and an integrated intensivist model (n = 910). Patients under the 2 models were comparable with respect to demographics, comorbidities, procedure types, and Society for Thoracic Surgery predicted risk of mortality score; however, patients in the earlier cohort were slightly older and more likely to have chronic kidney disease ( P = .003). Integrated intensivist involvement was associated with reduced postoperative ventilator time, length of stay (LOS), stroke, encephalopathy, and reoperations for bleeding (all P < .01) but was not associated with mortality. Intensivist integration into the postoperative care of cardiac surgery patients may reduce ventilator time, LOS, and complications but may not improve survival. PMID- 29590757 TI - Hope Tree: An Interactive Art Installation to Facilitate the Expression of Hope in a Hospice Setting. AB - BACKGROUND: Individuals confronting a terminal illness can experience intense psychological distress. Previous research has shown that hope can enhance one's ability to acknowledge, accept, and fight a terminal illness. Patients can continue to have hope or be hopeful, even in the face of a terminal illness. Can participation in a creative writing practice improve the expression of hope in a hospice setting? METHODS: In this program evaluation, each expressed hope placed on the "Hope Tree" was independently coded by all research team members utilizing inductive content analysis. Overall themes were derived using a constant comparative approach and arranged into overarching themes based on consensus. RESULTS: Eight major themes emerged from the data: "Peace," "Dreams," "Total well being," "Acknowledgment of loss," "Relationships," "Hospice care," "Spirituality," and "Dichotomies." CONCLUSION: The Hope Tree is a creative art project that can be used within a hospice environment to promote hope among family members and the health-care professionals who care for patients. PMID- 29591320 TI - Lumbrical muscle tear: clinical presentation, imaging findings and outcome. AB - : The incidence of lumbrical muscle tear is increasing due to the popularity of climbing sport. We reviewed data from 60 consecutive patients with a positive lumbrical stress test, including clinical examination, ultrasound and clinical outcomes in all patients, and magnetic resonance imaging in 12 patients. Fifty seven patients were climbers. Lumbrical muscle tears were graded according to the severity of clinical and imaging findings as Grade I-III injuries. Eighteen patients had Grade I injuries (microtrauma), 32 had Grade II injuries (muscle fibre disruption) and 10 had Grade III injuries (musculotendinous disruption). The treatment consisted of adapted functional therapy. All patients completely recovered and were able to return to climbing. The healing period in Grade III injuries was significantly longer than in the patients with Grade I or II injuries ( p < 0.001). We recommend evaluation of specific clinical and imaging findings to grade the injuries and to determine suitable therapy. LEVEL OF EVIDENCE: IV.

After using the shotgun approach, fixation was carried out when the anterior fragment was large enough to accept two 1.5 mm screws. Sixty-three fracture-dislocations were treated in 61 patients, of whom 30 underwent internal fixation. Twenty-one of these were assessed in the final study. At a mean follow-up of 29 months, the mean range of joint motion was 80 degrees and 102 degrees for the injured and contralateral hand, respectively. The mean pinch and grip strengths of injured hand were 82% and 83% of contralateral hand, respectively. The mean disabilities of the arm, shoulder and hand score was 5.5. The mean visual analogue pain score was 1.6. Surgery through the versatile shotgun approach allows excellent intra-operative assessment and acceptable outcomes. LEVEL OF EVIDENCE: IV. PMID- 29591369 TI - Pharmacists' Impact on Secondary Stroke Prevention. AB - BACKGROUND: Patients admitted to our institution with a cerebrovascular accident (stroke) or transient ischemic attack (TIA) are referred to the pharmacist-run stroke prevention clinic (SPC) for medication and risk factor management. OBJECTIVE: The objective was to determine if patients receiving care from the SPC have better outcomes than patients who received usual care. METHODS: This was a retrospective chart review of patients referred to the SPC. At the time of stroke/TIA, before initial visit, and after last SPC visit, risk factor data was collected. Hospital readmissions were reviewed for secondary stroke/TIA, myocardial infarction (MI), and new or incidental peripheral artery disease (PAD). For patients that did not attend SPC visits, data was used as a control. RESULTS: Patients referred to the SPC from October 2012 to December 2014 were reviewed. 455 records were reviewed. The primary composite end point of readmission for stroke/TIA, myocardial infarction, and new or incidental PAD was statistically significantly lower in the SPC group than the control group ( P = .013). All surrogate markers, including blood pressure, Low Density Lipoprotein, Hemoglobin A1c, and smoking status, improved in the SPC group. CONCLUSION: Pharmacists can play a role in reducing risk factors for secondary stroke/TIA and prevent future hospital admissions. PMID- 29591488 TI - Prediction of microRNA-binding residues in protein using a Laplacian support vector machine based on sequence information. AB - The identification of microRNA (miRNA)-binding protein residues significantly impacts several research areas, including gene regulation and expression. We propose a method, PmiRBR, which combines a novel hybrid feature with the Laplacian support vector machine (LapSVM) algorithm to predict miRNA-binding residues in protein sequences. The hybrid feature is constituted by secondary structure, conservation scores, and a novel feature, which includes evolutionary information combined with the physicochemical properties of amino acids. Performance comparisons of the various features indicate that our novel feature contributes the most to prediction improvement. Our results demonstrate that PmiRBR can achieve 85.96% overall accuracy, with 43.89% sensitivity and 90.56% specificity. PmiRBR significantly outperforms other approaches at miRNA-binding residue prediction. PMID- 29591533 TI - Peritoneal dialysis catheter insertion surgery and management. AB - Peritoneal access surgery is the first step to achieve successful peritoneal dialysis. It is important to perform easy, safe, and less invasive surgery of peritoneal dialysis catheter insertion. Secure peritoneal dialysis catheter insertion will lead to less infection, that is, exit site, tunnel infection, and peritonitis, which sometimes result in peritoneal dialysis discontinuation. To avoid these undesirable results, we should perform good and proper peritoneal dialysis insertion surgery. In this article, we describe peritoneal dialysis catheter insertion surgery and its management. PMID- 29591534 TI - Physical activity volume in relation to risk of atrial fibrillation. A non-linear meta-regression analysis. AB - Background Light physical activity is known to reduce atrial fibrillation risk, whereas moderate to vigorous physical activity may result in an increased risk. However, the question of what volume of physical activity can be considered beneficial remains poorly understood. The scope of the present work was to examine the relation between physical activity volume and atrial fibrillation risk. Design A comprehensive systematic review was performed following the PRISMA guidelines. Methods A non-linear meta-regression considering the amount of energy spent in physical activity was carried out. The first derivative of the non linear relation between physical activity and atrial fibrillation risk was evaluated to determine the volume of physical activity that carried the minimum atrial fibrillation risk. Results The dose-response analysis of the relation between physical activity and atrial fibrillation risk showed that physical activity at volumes of 5-20 metabolic equivalents per week (MET-h/week) was associated with significant reduction in atrial fibrillation risk (relative risk for 19 MET-h/week = 0.92 (0.87, 0.98). By comparison, physical activity volumes exceeding 20 MET-h/week were unrelated to atrial fibrillation risk (relative risk for 21 MET-h/week = 0.95 (0.88, 1.02). Conclusion These data show a J-shaped relation between physical activity volume and atrial fibrillation risk. Physical activity at volumes of up to 20 MET-h/week is associated with reduced atrial fibrillation risk, whereas volumes exceeding 20 MET-h/week show no relation with risk.

PMID- 29591536 TI - Sequence typing of human adenoviruses isolated from Polish patients subjected to allogeneic hematopoietic stem cell transplantation - a single center experience. AB - PURPOSE: Human adenoviruses (HAdV) from species A, B and C are commonly recognized as pathogens causing severe morbidity and mortality in hematopoietic stem cell transplant (HSCT) recipients. The purpose of the present study was to determine HAdV types responsible for viremia in HSCT recipients at a large tertiary hospital in Poland. METHODS: Analysis of partial nucleotide sequences of HAdV hexon gene was used to type 40 clinical isolates of HAdV obtained from 40 HSCT recipients. RESULTS: We identified six different HAdV serotypes belonging to species B, C and E. We demonstrated high variability in sequences of detected HAdV types, and patients infected with the same HAdV types were not hospitalized at the same time, which suggests the low possibility of cross-infection. In almost all patients, anti-HAdV antibodies in IgG class were detected, which indicates a history of HAdV infection in the past. Clinical symptoms accompanying HAdV viremia were in 89%, and in 61.5% of individuals, HAdV was a sole pathogen detected. There were no cases with high-level HAdV viremia and severe systemic or organ infections. Graft-versus-host disease (GvHD) was present in patients infected with species B and C, but grade II of GvHD was observed only in patients infected with HAdV-B. CONCLUSIONS: The predominance of HAdV-C and common presence of anti-HAdV antibodies in IgG class may strongly suggest that most infections in the present study were reactivations of HAdV persisting into the patient's mucosa associated lymphoid tissues. Variability of HAdV sequences suggests that cross infections between patients were very rare. ABBREVIATIONS: GvHD: graft-versus host disease; HAdV: human adenoviruses; HSCT: hematopoietic stem cell transplantation. PMID- 29591537 TI - Is Ego Depletion Real? An Analysis of Arguments. AB - An influential line of research suggests that initial bouts of self-control increase the susceptibility to self-control failure (ego depletion effect). Despite seemingly abundant evidence, some researchers have suggested that evidence for ego depletion was the sole result of publication bias and p-hacking, with the true effect being indistinguishable from zero. Here, we examine (a) whether the evidence brought forward against ego depletion will convince a proponent that ego depletion does not exist and (b) whether arguments that could be brought forward in defense of ego depletion will convince a skeptic that ego depletion does exist. We conclude that despite several hundred published studies, the available evidence is inconclusive. Both additional empirical and theoretical works are needed to make a compelling case for either side of the debate. We discuss necessary steps for future work toward this aim. PMID- 29591538 TI - Quality Measurement Recommendations Relevant to Clinical Guidelines in Germany and the United Kingdom: (What) Can We Learn From Each Other? AB - We conducted a systematic review of clinical guidelines (CGs) to examine the methodological approaches of quality indicator derivation in CGs, the frequency of quality indicators to check CG recommendations in routine care, and clinimetric properties of quality indicators. We analyzed the publicly available CG databases of the Association of the Scientific Medical Societies in Germany (AWMF) and National Institute for Health and Care Excellence (NICE). Data on the methodology of subsequent quality indicator derivation, the content and definition of recommended quality indicators, and clinimetric properties of measurement instruments were extracted. In Germany, no explicit methodological guidance exists, but 3 different approaches are used. For NICE, a general approach is used for the derivation of quality indicators out of quality standards. Quality indicators were defined in 34 out of 87 CGs (39%) in Germany and for 58 out of 133 (43%) NICE CGs. Statements regarding measurement properties of instruments for quality indicator assessment were missing in German and NICE documents. Thirteen pairs of CGs (32%) have associated quality indicators. Thirty four quality indicators refer to the same aspect of the quality of care, which corresponds to 27% of the German and 7% of NICE quality indicators. The development of a standardized and internationally accepted methodology for the derivation of quality indicators relevant to CGs is needed to measure and compare quality of care in health care systems. PMID- 29591539 TI - Reducing High-Users' Visits to the Emergency Department by a Primary Care Intervention for the Uninsured: A Retrospective Study. AB - Reducing avoidable emergency department (ED) visits is an important health system goal. This is a retrospective cohort study of the impact of a primary care intervention including an in-hospital, free, adult clinic for poor uninsured patients on ED visit rates and emergency severity at a nonprofit hospital. We studied adult ED visits during August 16, 2009-August 15, 2011 (preintervention) and August 16, 2011-August 15, 2014 (postintervention). We compared pre- versus post-mean annual visit rates and discharge emergency severity index (ESI; triage and resource use-based, calculated Agency for Healthcare Research and Quality categories) among high-users (>=3 ED visits in 12 months) and occasional users. Annual adult ED visit volumes were 16 372 preintervention (47.5% by high-users), versus 18 496 postintervention. High-users' mean annual visit rates were 5.43 (top quartile) and 0.94 (bottom quartile) preintervention, versus 3.21 and 1.11, respectively, for returning high-users, postintervention (all P < .001). Postintervention, the visit rates of new high-users were lower (lowest and top quartile rates, 0.6 and 3.23) than preintervention high-users' rates in the preintervention period. Visit rates of the top quartile of occasional users also declined. Subgroup analysis of medically uninsured high-users showed similar results. Upon classifying preintervention high-users by emergency severity, postintervention mean ESI increased 24.5% among the lowest ESI quartile, and decreased 12.2% among the top quartile. Pre- and post-intervention sample demographics and comorbidities were similar. The observed reductions in overall ED visit rates, particularly low-severity visits; highest reductions observed among high-users and the top quartile of occasional users; and the pattern of changes in emergency severity support a positive impact of the primary care intervention. PMID- 29591540 TI - Comprehensive Support for Family Caregivers of Post-9/11 Veterans Increases Veteran Utilization of Long-term Services and Supports: A Propensity Score Analysis. AB - Family caregivers are an important component of the long-term services and supports (LTSS) system. However, caregiving may have negative consequences for caregiver physical and emotional health. Connecting caregivers to formal short term home- and community-based services (HCBS), through information resources and referrals, might alleviate family caregiver burden and delay nursing home entry for the patient. The aim of this study was to evaluate the early impact of the Program of Comprehensive Assistance for Family Caregivers (PCAFC) (established by P.L. 111-163 for family caregivers of seriously injured post-9/11 Veterans) on Veteran use of LTSS. A two-cohort pre-post design with a nonequivalent comparison group (treated n = 15 650; comparison n = 8339) was used to (1) examine the association between caregiver enrollment in PCAFC and any VA-purchased or VA provided LTSS use among Veterans and (2) describe program-related trends in HCBS and institutional LTSS use. The comparison group was an inverse-propensity-score weighted sample of Veterans whose caregivers applied for, but were not accepted into, the program. From baseline through 24 months post application, use of any LTSS ranged from 13.1% to 17.8% for Veterans whose caregivers were enrolled in PCAFC versus from 3.8% to 5.3% for Veterans in the comparison group. Participation in PCAFC was associated with a statistically significant increased use of any LTSS from 1 to 24 months post application (over time odds ratios ranged from 2.71 [95% confidence interval: 2.31-3.17] to 4.86 [3.93-6.02]). Support for family caregivers may enhance utilization of LTSS for Veterans with physical, emotional, and/or cognitive conditions. PMID- 29591587 TI - Perceived Calling and Work Engagement Among Nurses. AB - The purpose of this study was to explore the relationship of perceived calling and work engagement in nursing over and above major work environment factors. In all, 351 nurses from various health care institutions completed the survey. Data were collected about the most demanding aspects of nursing, major job resources, the degree to which nursing is perceived as a meaningful calling, work engagement, and main demographic information. Hierarchical linear regression was applied to assess the relation between perceived calling and work engagement, while controlling for demographic and work environment factors, and perceived calling was significantly related to two out of three components of nurses' work engagement. The highest association was found with dedication component, and vigor component was related insignificantly. Results have shown that perceived calling might motivate nurses to engage in their work even in burdensome environment, although possible implications for the occupational well-being of nurses themselves remains unclear. PMID- 29591721 TI - "Twig-like" cerebral vessels are not pathognomonic for ACTA A2 mutations: A case report. AB - ACTA2 mutations are recently described genetically defined abnormalities of blood vessels in various organs of the body with specific abnormalities in cerebral vessels in the form of straightening of all cerebral arteries ("twig-like" pattern), stenosis/occlusions, proximal dilatation, and absent "moyamoya" type of collaterals. We describe a one-and-a half year-old girl child who presented with mild motor developmental delay and on neuroimaging showed septo-preoptic holoprosencephaly, diffuse radial polymicrogyria, and pontine hypoplasia along with magnetic resonance angiographic features suggestive of ACTA2 mutation type of cerebral vessels. However, genetic studies revealed no evidence of ACTA2 mutation, indicating that the "twig-like" pattern may not only be a pathognomonic feature of ACTA2 mutations. PMID- 29591722 TI - High-throughput terrestrial biodiversity assessments: mitochondrial metabarcoding, metagenomics or metatranscriptomics? AB - Consensus on the optimal high-throughput sequencing (HTS) approach to examine biodiversity in mixed terrestrial arthropod samples has not been reached. Metatranscriptomics could increase the proportion of taxonomically informative mitochondrial reads in HTS outputs but has not been investigated for terrestrial arthropod samples. We compared the efficiency of 16S rRNA metabarcoding, metagenomics and metatranscriptomics for detecting species in a mixed terrestrial arthropod sample (pooled DNA/RNA from 38 taxa). 16S rRNA metabarcoding and nuclear rRNA-depleted metatranscriptomics had the highest detection rate with 97% of input species detected. Based on cytochrome c oxidase I, metagenomics had the highest detection rate with 82% of input species detected, but metatranscriptomics produced a larger proportion of reads matching (Sanger) reference sequences. Metatranscriptomics with nuclear rRNA depletion may offer advantages over metabarcoding through reducing the number of spurious operational taxonomic units while retaining high detection rates, and offers natural enrichment of mitochondrial sequences which may enable increased species detection rates compared with metagenomics. PMID- 29591635 TI - Are cannabis-using and non-using patients different groups? Towards understanding the neurobiology of cannabis use in psychotic disorders. AB - A substantial body of credible evidence has accumulated that suggest that cannabis use is an important potentially preventable risk factor for the development of psychotic illness and its worse prognosis following the onset of psychosis. Here we summarize the relevant evidence to argue that the time has come to investigate the neurobiological effects of cannabis in patients with psychotic disorders. In the first section we summarize evidence from longitudinal studies that controlled for a range of potential confounders of the association of cannabis use with increased risk of developing psychotic disorders, increased risk of hospitalization, frequent and longer hospital stays, and failure of treatment with medications for psychosis in those with established illness. Although some evidence has emerged that cannabis-using and non-using patients with psychotic disorders may have distinct patterns of neurocognitive and neurodevelopmental impairments, the biological underpinnings of the effects of cannabis remain to be fully elucidated. In the second and third sections we undertake a systematic review of 70 studies, including over 3000 patients with psychotic disorders or at increased risk of psychotic disorder, in order to delineate potential neurobiological and neurochemical mechanisms that may underlie the effects of cannabis in psychotic disorders and suggest avenues for future research.

PMID- 29591724 TI - Two-Year Outcomes of the Nellix EndoVascular Aneurysm Sealing System for Treatment of Abdominal Aortic Aneurysms. AB - PURPOSE: To analyze the 2-year outcomes of endovascular aneurysm sealing (EVAS) according to 2 versions of the instructions for use (IFU). METHODS: A retrospective study was conducted involving 355 consecutive patients treated with the first-generation EVAS device from April 2013 to December 31, 2015, at 3 high volume centers. Out of 355 patients treated with EVAS, 264 were elective asymptomatic infrarenal EVAS procedures suitable for analysis. In this cohort, 168 (63.3%) patients were treated within the IFU 2013 criteria; of these 48 (18.2%) were in compliance with the revised IFU 2016 version. RESULTS: Overall technical success was 98.2% (165/168) in the IFU 2013 group and 97.9% (47/48) in the IFU 2016 subgroup (p=0.428). The 2-year freedom from reintervention estimates were 89.7% (IFU 2013) and 95.7% (IFU 2016), with significantly more reinterventions in the first 45 cases (p=0.005). The stenosis/occlusion estimates were 6.5% (IFU 2013) and 4.2% (IFU 2016; p=0.705). Nine (5.4%) endoleaks (8 type Ia and 1 type Ib) were observed within the IFU 2013 cohort; 3 (2.1%) were in the IFU 2016 subgroup (p=0.583). Migration >=10 mm or >=5 mm requiring intervention was reported in 12 (7.1%) patients in the IFU 2013 cohort but none within the IFU 2016 subgroup. Ten (6.0%) patients demonstrated aneurysm growth in the IFU 2013 cohort, of which 2 (4.2%) were in the IFU 2016 subgroup. Overall survival and freedom from aneurysm-related death estimates at 2 years were 90.9% and 97.6% in the IFU 2013 cohort (IFU 2016: 95.5% and 100.0%). The prevalence of complications seemed lower within IFU 2016 without significant differences. CONCLUSION: This study shows acceptable 2-year results of EVAS used within the IFU, without significant differences between the 2 IFU versions, though longer follow-up is indicated. The refined IFU significantly reduced the applicability of the technique. PMID- 29591838 TI - Getting comfortable with "comfort feeding": An exploration of legal and ethical aspects of the Australian speech-language pathologist's role in palliative dysphagia care. AB - PURPOSE: With an ageing population, speech-language pathologists (SLPs) can expect to encounter legal and ethical challenges associated with palliative and end-of-life care more frequently. An awareness of the medico-legal and ethical framework for palliative dysphagia management will better equip SLPs to work effectively in this area. METHOD: This narrative review examines a range of legislation, legal, ethical and SLP literature that is currently available to orient SLPs to legal and ethical palliative dysphagia management in the Australian context. RESULT: Relevant legal and ethical considerations in palliative and end-of-life care are described. CONCLUSION: SLPs have a role in palliative dysphagia management, however, this can involve unique legal and ethical challenges. The legal position on provision and cessation of nutrition and hydration differs between Australian States and Territories. Decisions by the courts have established a body of relevant case law. This article introduces SLPs to some of the important considerations for legal and ethical palliative care, but is not intended to be directive. SLPs are encouraged to explore their local options for ethical and medico-legal guidance. It is hoped that increasing SLPs awareness of many of the concepts discussed in this article enhances the provision of high-quality patient-centred care. PMID- 29591780 TI - A comparison of the effects of carbon dioxide and medical air for abdominal insufflation on respiratory parameters in xylazine-sedated sheep undergoing laparoscopic artificial insemination. AB - AIMS: To determine if abdominal insufflation with medical air will improve oxygenation and ventilation parameters when compared to insufflation with CO2 in xylazine-sedated sheep undergoing laparoscopic artificial insemination (AI). METHODS: Forty-seven sheep underwent oestrus synchronisation and were fasted for 24 hours prior to laparoscopic AI. Each animal was randomised to receive either CO2 or medical air for abdominal insufflation. An auricular arterial catheter was placed and utilised for serial blood sampling. Respiratory rates (RR) and arterial blood samples were collected at baseline, after xylazine (0.1 mg/kg I/V) sedation, 2 minutes after Trendelenburg positioning, 5 minutes after abdominal insufflation, and 10 minutes after being returned to a standing position. Blood samples were collected in heparinised syringes, stored on ice, and analysed for arterial pH, partial pressure of arterial O2 (PaO2), and CO2 (PaCO2). The number of ewes conceiving to AI was also determined. RESULTS: Repeated measures ANOVA demonstrated temporal effects on RR, PaO2, PaCO2 and arterial pH during the laparoscopic AI procedure (p<0.001), but no difference between insufflation groups (p>0.01). No sheep experienced hypercapnia (PaCO2>50 mmHg) or acidaemia (pH<7.35). Hypoxaemia (PaO2<70 mmHg) was diagnosed during the procedure in 14/22 (64%) ewes in the CO2 group compared with 8/23 (35%) ewes in the medical air group (p=0.053). Overall, 15/20 (75%) ewes in the CO2 group conceived to AI compared with 16/22 (72.7%) in the medical air group (p=0.867). CONCLUSIONS AND CLINICAL RELEVANCE: There were no statistical or clinical differences in RR, PaO2, PaCO2, pH, or conception to AI when comparing the effects of CO2 and medical air as abdominal insufflation gases. None of the sheep experienced hypercapnia or acidaemic, yet 42% (19/45) of sheep developed clinical hypoxaemia, with a higher percentage of ewes in the CO2 group developing hypoxaemia than in the medical air group. Based on the overall analysis, medical air could be utilised as a comparable alternative for abdominal insufflation during laparoscopic AI procedures. PMID- 29591886 TI - Investigation of the genotoxic and cytotoxic effects of widely used neonicotinoid insecticides in HepG2 and SH-SY5Y cells. AB - Neonicotinoids are a relatively new type of insecticide to control a variety of pests. Although they are generally considered to be safe, they can lead to harmful effects on human and environmental health. We aimed to investigate possible effects of common neonicotinoid insecticides (acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam) on cytotoxicity and DNA damage in human neuroblastoma (SH-SY5Y) and human hepatocellular carcinoma (HepG2) cells. Our results indicated that 50% of inhibitory concentration values of neonicotinoids are in the range of 0.96 to >4 mM in SH-SY5Y cells and 0.53 to >4 mM in HepG2 cells by the methyl tetrazolium and neutral red uptake tests after 24 and 48 h exposure. We observed significant DNA damage at 500 uM of five neonicotinoids in SHSY-5Y cells, while only imidacloprid, thiametoxam, and thiacloprid showed some alterations in HepG2 cells after 24 h exposure using the alkaline comet assay. In conclusion, neonicotinoid insecticides may induce cytotoxicity and DNA damage in cell cultures; therefore, further studies are needed to better understand the toxicity of neonicotinoids. PMID- 29591887 TI - Pathology of cigarettes on the reproductive system and ameliorative effects of alpha lipoic acid: A rat model study. AB - Cigarette smoking (CS) has some detrimental effects that occur via oxidative stress (OS). The aim of this work was to demonstrate the pathological and immunohistochemical effects of CS and the protective effects of a strong antioxidant alpha lipoic acid (ALA) on CS-induced genital system changes in a rat model. Twenty-eight female rats were randomly allocated to three groups as control, CS-exposed, and CS-exposed and ALA-treated. Reproductive tract organs were collected for biochemical and pathological examinations. In the CS group, OS markers increased in the tissues of both the ovary and fallopian tubes. Decreased follicle numbers in the ovary, marked cilial loss in the fallopian tubes, and pathologic changes in the uterus were observed in the CS group. Positive calcitonin gene-related peptide (CGRP), caspase 3alpha, hypoxia-inducible factor 1alpha (HIF-1alpha), tumor necrosis factor-alpha (TNF-alpha) immunoreactions were observed in uterine tissues and HIF-1alpha immunoreactions in tubal and uterine epithelial cells of the CS group. ALA reversed all these findings effectively. CS has negative effects on the female reproductive system via HIF-1alpha in tuba uterina and HIF-1alpha, HIF-2alpha, TNF-alpha, caspase 3, and CGRP in the uterus, and ALA could protect against the negative effects of CS on the female reproductive system. PMID- 29591888 TI - Effects of T-2 and Fumonisin B1 combined treatment on in vitro mouse embryo development and blastocyst quality. AB - In the temperate region, most common mycotoxins are members of fusariotoxins. It often happens that food and forage are contaminated with two or more fusariotoxins at the same time. Effects of co-contamination are poorly documented, especially in the field of reproduction. The aim of our study was to assess the combined effect of the two common fusariotoxins, T-2 toxin (T-2) and Fumonisin B1 on early mouse embryo development in vitro. Embryo culture media contained either (1) 0.5 ng/ml T-2; 1, 2, or 10 ng/ml FB1 (group A, B, and C, respectively); or (2) 0.5 ng/ml T-2 and 1, 2, or 10 ng/ml FB1 (group TA, TB, and TC, respectively). Developmental rate, blastocoel expansion, cell number, and micronucleus rate were measured following 96 h culture. Although the developmental rate was similar to the control group (86.43% vs. 83.33, 78.79, 85.98, and 86.67%, respectively) in the case of single toxin treatments, the combined treatments induced significant decreases (14.5, 33.6, and 22.8% in TA, TB, and TC, respectively). The proportion of late blastocysts was lower in all treatments compared to control (83.6% vs. 0-83.6%). Combined treatment resulted in a significantly lower proportion of late blastocysts (25% in TA and 0% in TB and TC). Cell numbers decreased in all toxin-treated groups with a higher rate after combined treatments. No differences were detected in the micronucleus rate in the single or combined treatments compared to control. Our study shows that T 2 and FB1 toxins do not necessarily decrease the developmental rate, but co contamination results in a significantly lower blastocyst rate and disturbs the blastocoel expansion as well. One possible explanation of this observation could be that the presence of two mycotoxins in the culture media intensifies their negative effects. All toxin treatments decreased the cell number in the blastocysts and this negative effect was more expressed after combined treatment. PMID- 29591889 TI - Impact of chromium and boron compounds on the reproductive function in rats. AB - The purpose of this research is to study the process of mutagenesis and the reproductive function in male rats under separate and combined exposure to chromium and boron compounds. The experiment was conducted on two groups of animals. The first group was used to assess the ability of potassium dichromate and boric acid to induce mutation in germ and somatic cells under isolated and combined administration with the use of the dominant lethal mutations test and the micronuclei test in the polychromatophilic erythrocytes of the bone marrow. The second group was used to test the combined and separate effect of the compounds under consideration on the reproductive function of male rats during the spermatogenesis cycle. When used in specific doses, boron compounds are a promising means of preventing and correcting chromium-induced effects in chromium production facility workers and people who live in ecologically adverse regions. PMID- 29591890 TI - Cadmium telluride quantum dots induce apoptosis in human breast cancer cell lines. AB - INTRODUCTION: Semiconductor quantum dots (QDs), especially those containing cadmium, have undergone marked improvements and are now widely used nanomaterials in applicable biological fields. However, great concerns exist regarding their toxicity in biomedical applications. Because of the lack of sufficient data regarding the toxicity mechanism of QDs, this study aimed to evaluate the cytotoxicity of three types of QDs: CdTe QDs, high yield CdTe QDs, and CdTe/CdS core/shell QDs on two human breast cancer cell lines MDA-MB468 and MCF-7. METHODS: The breast cancer cells were treated with different concentrations of QDs, and cell viability was evaluated via MTT assay. Hoechst staining was applied for observation of morphological changes due to apoptosis. Apoptotic DNA fragmentation was visualized by the agarose gel electrophoresis assay. Flow cytometric annexin V/propidium iodide (PI) measurement was used for apoptosis detection. RESULTS: A significant decrease in cell viability was observed after QDs treatment ( p < 0.05). Apoptotic bodies and chromatin condensation was observed by Hoechst staining. DNA fragmentation assay demonstrated a DNA ladder profile in the exposed cells and also annexin V/PI flow cytometry confirmed apoptosis in a dose-dependent manner. CONCLUSION: Our results revealed that CdTe, high yield CdTe, and CdTe/CdS core/shell QDs induce apoptosis in breast cancer cell lines in a dose-dependent manner. This study would help realizing the underlying cytotoxicity mechanism, at least partly, of CdTe QDs and may provide information for the development of nanotoxicology and safe use of biological applications of QDs. PMID- 29591914 TI - The Bethesda System for Reporting Thyroid Cytopathology Explained for Practitioners: Frequently Asked Questions. AB - BACKGROUND: The recent update of The Bethesda System for Reporting Thyroid Cytology (TBSRTC) is a very important development in the evaluation of thyroid nodules. Clinical experience and scientific literature both show that practitioners performing thyroid fine-needle aspiration are accustomed to basing the clinical management of patients on reports using TBSRTC. Specifically, clinicians are familiar with the percent risk of malignancy corresponding to each TBSRTC diagnostic category (DC), as well as with the respective recommendation for clinical management. However, most clinicians are much less familiar with the specific considerations that lie between a given DC, on the one end, and the respective risk of malignancy and associated management recommendation, on the other end. SUMMARY: A deeper understanding of the system can enlighten the clinician's thinking about the specific nodule under examination and can guide the decision-making process in a more meaningful way. Such an understanding can only be developed via close two-way communication between cytopathologists and clinicians. Through this type of interaction in the authors' tertiary medical center, recurring issues of particular importance for clinical practice were identified, which are reported here in the form of 16 frequently asked questions posed by the clinician to the cytopathologist. CONCLUSIONS: For each frequently asked question, an answer is provided based on the literature, the authors' experience, the new version of TBSRTC, and the new World Health Organization classification of tumors of endocrine organs. PMID- 29592134 TI - Erratum. PMID- 29592135 TI - Accumulation of Deleterious Mutations in Endosymbionts: Muller's Ratchet with Two Levels of Selection. AB - Many eukaryotes host mutualistic, maternally transmitted prokaryotic symbionts. Two kinds of evolution within symbiont genomes threaten to erode the benefits of these associations. First, because symbionts reproduce asexually, are sequestered within hosts, and undergo bottlenecks at infection, they are subject to the long term accumulation of deleterious mutations through Muller's ratchet. Second, "selfish" mutations, benefiting symbionts at host expense, could cause the ultimate decline of both host and symbionts. We performed simulations to assess how the fate of each mutation type is affected by host population size, numbers of symbionts transmitted to progeny, selection within and between hosts, and mutation rate. Fixation rate always increases with decreasing host population size. However, fixation rates for uniformly deleterious and selfish mutations are oppositely affected by varying transmission numbers, with increased numbers slowing accumulation of strictly deleterious mutations, especially for effects concentrated within hosts, but speeding fixation of "selfish" mutations. In aphid symbionts, most genes underlie basic cellular processes and are probably selected at both levels, but a substantial minority of genes contribute only to host fitness. No inoculum size is optimal for minimizing deleterious evolution for both categories of gene. PMID- 29592136 TI - The Imprint of History on Communities of North American and Asian Warblers. AB - The ecology of the component species of an adaptive radiation is likely to be influenced by the form of the founding ancestor to the radiation, its timing, and rates of speciation and extinction. These historical features complement environmental selection pressures. They imply that, if the history of the species' radiations are very different, ecological communities are unlikely to be completely convergent even when placed in identical environments. We compare the adaptive radiation of the Dendroica warblers of North America with that of the Phylloscopus warblers of Asia. We consider the ecology of the species in two localities where species' diversity is very high (New Hampshire, U.S.A., and Kashmir, India, respectively) and contrast the history of the two radiations on the basis of a molecular (mitochondrial cytochrome b) phylogeny. By comparison with the Phylloscopus, the Dendroica are on average larger and morphologically more similar to one another. Although there is some similarity between the Dendroica and Phylloscopus communities, they differ in foraging behavior and in associations of morphology with ecological variables. The Dendroica likely reflect an early Pliocene radiation and are two to four times younger than the Phylloscopus. They probably had a colorful sexually dichromatic ancestor, implicating sexual selection in the production of the many ecologically similar species. The Phylloscopus are much older and probably had a drab, monomorphic ancestor. Given the difference in ages of the two radiations, it is plausible that the close species' packing of the Dendroica warblers is a transient phenomenon. If this is the case, community structure evolves on the timescales of millions of years. Differences in ancestry and timing of the species' radiations can be related to the different biogeography of the two regions. This implies that the historical imprint on adaptive radiations could be predicted on the basis of the attributes of ancestors and biogeographical context. PMID- 29592137 TI - Facilitation May Buffer Competitive Effects: Indirect and Diffuse Interactions among Salt Marsh Plants. AB - Direct interactions among plant species may be highly modified by indirect or diffuse effects within a multispecies community. We investigated the direct and diffuse effects of two salt marsh perennials, Monanthechloe littoralis and Arthrocnemum subterminale, on winter annuals and the perennial herb Limonium californicum in a salt marsh in central California. In permanent plots, Monanthechloe had expanded substantially in the upper marsh over the past 13 yr, while Arthrocnemum and all annual species had decreased. These dynamics suggest that Monanthechloe may directly outcompete most other species in the upper marsh. In contrast, Arthrocnemum is known to facilitate some annual species. In our field experiments, Monanthechloe strongly suppressed Arthrocnemum, all four common annual species, and Limonium in direct interactions. In contrast, Arthrocnemum directly facilitated the winter annuals Parapholis incurva and Lasthenia glabrata, competed with Spergularia marina, and did not have a significant effect on Limonium. However, when the combined effects of Monanthechloe and Arthrocnemum were tested, Arthrocnemum ameliorated the negative effect of Monanthechloe on all four species. Although isolated Arthrocnemum competed with Spergularia and had no direct effects on Limonium, Arthrocnemum in the presence of Monanthechloe facilitated both species. We hypothesize that Arthrocnemum buffered the strong competitive effects of Monanthechloe on Lasthenia and Parapholis via direct positive effects and benefited Spergularia and Limonium through its competitive effect on Monanthechloe. These findings add to the growing body of literature emphasizing the importance of diversity and interdependence in the functioning of plant communities. PMID- 29592138 TI - How Males Can Gain by Harming Their Mates: Sexual Conflict, Seminal Toxins, and the Cost of Mating. AB - We suggest that damaging mating tactics, such as physical aggression, the evolution of genital barbs and spines, and the transfer of seminal toxins may serve as a general means by which males can induce females to avoid or to delay remating. Provided that cumulative damage has an accelerating impact on fitness, a female who has already been harmed by previous partner(s) may do best to refrain from remating to avoid suffering still further damage. Consequently, a male can gain through the imposition of mating costs, even though this may reduce female fitness because by doing so he minimizes the chances that his mate will copulate again. We develop a game theoretical model of this possibility, focusing on toxin transfer as an illustrative example. We show that toxicity as a means of inhibiting remating is phenotypically stable over a broad range of conditions (although, under some circumstances, it may be necessary to invoke other selective pressures to account for the initial evolution of toxicity). The model predicts that toxin transfer should be more common (and involve greater levels of toxicity) in species with greater last-male mating advantage; it is also most likely where the poison inflicts strongly accelerating, dose-dependent costs on females. PMID- 29592139 TI - The Relative Importance of Competition and Predation Varies with Productivity in a Model Community. AB - Recent theory predicts that productivity can influence the relative importance of predation and competition in determining patterns in abundance, diversity, and community structure. In low-productivity systems, competition is predicted to be the major influence on community patterns, while at high productivity, the major influence is predicted to be predation. We directly tested this theory using a laboratory model community. Our model community consisted of the bacteriophage T2 (a virus that feeds on Escherichia coli) and two populations of E. coli, in glucose-limited chemostats. One E. coli population consisted of individuals that were sensitive to predation by T2 ("vulnerable" E. coli), and the other population consisted of individuals that were partially resistant to predation by T2 ("less vulnerable" E. coli). We manipulated productivity in this experiment by running replicate chemostats with different input concentrations of glucose. Our observations were consistent with theoretical predictions. We observed the decline of the more vulnerable prey population at higher productivity but not at lower productivity, and the decline of the less vulnerable prey population at lower productivity but not at higher productivity. However, the rate of decline in some replicates was slower than predicted, and extinctions were not observed during the experiments, contrary to theoretical predictions. We present some testable hypotheses that might explain the slow rate of decline observed. PMID- 29592140 TI - Adaptive Evolution of Seed Oils in Plants: Accounting for the Biogeographic Distribution of Saturated and Unsaturated Fatty Acids in Seed Oils. AB - Structural, energetic, biochemical, and ecological information suggests that germination temperature is an important selective agent causing seed oils of higher-latitude plants to have proportionately more unsaturated fatty acids than lower-latitude plants. Germination temperature is predicted to select relative proportions of saturated and unsaturated fatty acids in seed oils that optimize the total energy stores in a seed and the rate of energy production during germination. Saturated fatty acids store more energy per carbon than unsaturated fatty acids; however, unsaturated fatty acids have much lower melting points than saturated fatty acids. Thus, seeds with lower proportions of saturated fatty acids in their oils should be able to germinate earlier and grow more rapidly at low temperatures even though they store less total energy than seeds with a higher proportion of saturated fatty acids. Seeds that germinate earlier and grow more rapidly should have a competitive advantage. At higher germination temperatures, seeds with higher proportions of saturated fatty acids will be selectively favored because their oils will provide more energy, without a penalty in the rate of energy acquisition. Macroevolutionary biogeographical evidence from a broad spectrum of seed plants and the genus Helianthus support the theory, as do microevolutionary biogeography and seed germination performance within species of Helianthus. PMID- 29592141 TI - Is Bergmann's Rule Valid for Mammals? AB - Bergmann's rule states that, within species of mammals, individuals tend to be larger in cooler environments. However, the validity of the rule has been debated. We examined the relationship between size and latitude as well as size and temperature within various species of mammals. We also tested the idea that smaller mammals follow Bergmann's rule more strongly than larger mammals, as expected if heat conservation is the cause of the rule. When all studies were included, the percentage of species showing a positive correlation between size and latitude was significantly >50% (78 of 110 species). Similarly, the percentage of species showing a negative correlation between size and temperature was significantly >50% (48 of 64). Analyses using only significant studies or only studies that sampled extensively also support Bergmann's rule. The size latitude and size-temperature trends were consistent within all orders and most families for which data are available. We did not find support for the hypothesis that smaller mammals conform more strongly to Bergmann's rule than larger mammals. Thus, we found broad support for Bergmann's rule as a general trend for mammals; however, our analyses do not support heat conservation as the explanation. PMID- 29592525 TI - Meis1 is specifically upregulated in kidney myofibroblasts during aging and injury but is not required for kidney homeostasis or fibrotic response. AB - The homeobox transcription factor Meis1 is required for mammalian development, and its overexpression plays a role in tumorigenesis, especially leukemia. Meis1 is known to be expressed in kidney stroma, but its function in kidney is undefined. We hypothesized that Meis1 may regulate stromal cell proliferation in kidney development and disease and tested the hypothesis using cell lineage tracing and cell-specific Meis1 deletion in development, aging, and fibrotic disease. We observed strong expression of Meis1 in platelet-derived growth factor receptor-beta-positive pericytes and perivascular fibroblasts, both in adult mouse kidney and to a lesser degree in human kidney. Either bilateral ischemia reperfusion injury or aging itself led to strong upregulation of Meis1 protein and mRNA in kidney myofibroblasts, and genetic lineage analysis confirmed that Meis1-positive cells proliferate as they differentiate into myofibroblasts after injury. Conditional deletion of Meis1 in all kidney stroma with two separate tamoxifen-inducible Cre recombinase drivers had no phenotype with the exception of consistent induction of the tubular injury marker kidney injury molecule-1 (Kim-1) only in Meis1 mutants. Further examination of Kim-1 expression revealed linkage disequilibrium of Kim-1 and Meis1, such that Meis1 mutants carried the longer BALB/c Kim-1 allele. Unexpectedly, we report that this Kim-1 allele is expressed at baseline in wild-type BALB/c mice, without any associated abnormalities, including long-term fibrosis, as predicted from the literature. We conclude that Meis1 is specifically expressed in stroma and myofibroblasts of mouse and human kidney, that it is not required for kidney development, disease, or aging, and that BALB/c mice unexpectedly express Kim-1 protein at baseline without other kidney abnormality. PMID- 29592526 TI - Combination exposure of melamine and cyanuric acid is associated with polyuria and activation of NLRP3 inflammasome in rats. AB - The molecular mechanisms of melamine-induced renal toxicity have not been fully understood. The purpose of the study aimed to investigate whether melamine and cyanuric acid induced NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation in the kidney, which may contribute to abnormal water and sodium handling in a rat model. Wistar rats received melamine (Mel; 200 mg.kg body wt-1.day-1), cyanuric acid (CA; 200 mg.kg body wt-1.day-1), or Mel plus CA (Mel + CA; 100 mg.kg body wt-1.day-1, each) for 2 wk. Mel + CA caused damaged tubular epithelial structure and organelles, dilated tubular lumen, and inflammatory responses. Crystals were observed in urine and serum specimen, also in the lumen of dilated distal renal tubules. The combined ingestion of Mel and CA in rats caused a markedly impaired urinary concentration, which was associated with reduced protein expression of aquaporin (AQP)1, 2, and 3 in inner medulla and alpha-Na-K-ATPase and Na-K-2Cl transporters in cortex and outer medulla. Mel + CA treatment was associated with increased protein expression of CD3 and mRNA levels of CD68 and F4/80 as well as phosphorylation of NF-kappaB in the kidney. Mel + CA treatment increased protein and mRNA expression of NLRP3 inflammasome components apoptosis-associated speck-like protein containing a caspase recruitment domain, caspase-1, and IL-1beta in the inner medulla of rats. NF kappaB inhibitor Bay 11-7082 reduced IL-1beta expression induced by Mel + CA and prevented downregulation of AQP2 in inner medullary collecting duct cell suspensions. In conclusion, Mel + CA treatment caused urinary-concentrating defects and reduced expression of renal AQPs and key sodium transporters, which is likely due to the inflammatory responses and activation of NLRP3 inflammasome induced by crystals formed in the kidney. PMID- 29592527 TI - The association between HIV clinical disease severity and psychiatric disorders as seen in Western Romania. AB - HIV disease continues to be a serious health issue all over the world. By the end of 2016, 36.7 million people were living with HIV, 1.8 million people became newly infected and 1 million died of HIV-related causes/diseases. In order to develop effective treatment strategies, is important to assess the risk factors that affect negatively the HIV-positive patients. HIV-infected patients are at high risk of developing psychiatric disorders in every stage of the illness. Psychiatric disorders can negatively influence the treatment adherence, induce risk behavior and influence the quality of life. The purpose of this study is to determine if the severity of HIV disease is associated with increased frequency of psychiatric disorders. We evaluated 101 HIV-positive patients receiving antiretroviral therapy in Western Romania via Psychiatric Diagnostic Screening Questionnaire (PDSQ). We conducted a risk analysis in order to see if the patients have a higher risk of developing psychiatric disorders depending on HIV serostatus factor (HIV asymptomatic, symptomatic, AIDS converted). Our study shows that, the patients having AIDS and symptomatic HIV have a higher prevalence for the most common psychiatric disorders: major depressive disorder (OR = 5.81;p < 0.001), panic disorder (OR = 3.11; p = 0.016), agoraphobia (OR = 4.31; p = 0.024), social phobia (OR = 2.81; p = 0.038), generalized anxiety disorder (OR = 4.79; p = 0.006), somatization (OR = 8.72; p < 0.0010) and hypochondria (OR = 4.66; p = 0.0013). Symptomatic HIV and AIDS converted serostatus is also a risk factor for post-traumatic stress disorder, obsessive-compulsive disorder and psychosis. The main conclusion of this study is that the more severe HIV clinical disease was associated with increased frequency of psychiatric disorders. As a consequence, we conclude that psychiatric disorders and HIV/AIDS treatment should be addressed simultaneously, depending on the risk specific factors such as the HIV infection stage and, due to psychiatric repercussions of HIV is expected to become more relevant in the coming years. PMID- 29592528 TI - Barriers and Facilitating Factors for Research Involvement in Cancer Centers: A Survey of Colorectal Cancer Center Coordinators in Germany, Austria, and Switzerland. AB - Improvements in health care depend on research involving health-care providers (HCPs) and health-care organizations (HCOs). Existing research suggests that involvement in research studies is still much lower than it could be. This study investigates factors that may impede or facilitate research involvement. A standardized online questionnaire was used to carry out a survey, in 3 countries, of key informants in colorectal cancer centers that hold certification in accordance with the requirements of the German Cancer Society. A total of 184 individuals responded (response rate 65%). The respondents found it difficult to identify studies suitable for their patients (40% agreement), criticized the small overall number of studies available (48%), and found that many studies are not worthwhile financially (56%). Among respondents who were not involved in studies as the principal investigators (PIs), 66% agreed they lacked the research infrastructure needed and 81% that they did not have enough staff. Among respondents who were involved as PIs, only 22% indicated that their hospital management encouraged them to initiate and conduct clinical trials. Eighty-five percent of the respondents agreed that the general population lacks information about the importance of studies. Five recommendations for health policy makers are derived from these findings for ways of increasing the involvement of HCPs and HCOs in research, and in cancer research in particular. PMID- 29592529 TI - A novel technique of axillary vein puncture involving peripherally inserted central venous catheters for a small basilic vein. AB - PURPOSE: Peripherally inserted central venous catheters are some of the most useful devices for vascular access used globally. Peripherally inserted central venous catheters have a low rate of fatal mechanical complications when compared to non-tunnel central venous catheters. However, as peripherally inserted central venous catheter access requires a smaller vein, there is a high risk of thrombosis. The axillary vein (confluence of the basilic and brachial veins) can serve as an access for cannulation. Moreover, as this vein is larger than the basilic or brachial vein, it might be a superior option for preventing thrombosis. The risk of catheter-related bloodstream infection should be considered when the puncture site is at the axillary fossa. The aim of this study was to present our new protocol involving peripherally inserted central venous catheters (non-tunneled/tunneled) and a tunneling technique and assess its feasibility and safety for improving cannulation and preventing thrombosis and infection. METHODS: The study included 20 patients. The axillary vein in the upper arm was used for peripherally inserted central venous catheters in patients with a small-diameter basilic vein (<3 mm). When the puncture site was in the axillary fossa, a subcutaneous tunnel of about 3 cm was constructed easily using a peripheral venous catheter. RESULTS: The observed catheter duration was 645 days (median +/- standard deviation, 26 +/- 22.22 days). Catheterization was successful in all cases, however, two accidental dislodgements were identified. No fatal or serious complications were observed after catheterization. CONCLUSION: Our new protocol for axillary peripherally inserted central venous catheters/tunneled axillary peripherally inserted central venous catheters use for a small-diameter basilic vein is safe and feasible.

PMID- 29592531 TI - Health literacy in familial hypercholesterolemia: A cross-national study. AB - Background High rates of inadequate health literacy are associated with maladaptive health outcomes in chronic disease including increased mortality and morbidity rates, poor treatment adherence and poor health. Adequate health literacy may be an important factor in the effective treatment and management of familial hypercholesterolemia, and may also be implicated in genetic screening for familial hypercholesterolemia among index cases. The present study examined the prevalence and predictors of health literacy in familial hypercholesterolemia patients attending clinics in seven countries. Design Cross-sectional survey. Methods Consecutive FH patients attending clinics in Australia, Brazil, China, Hong Kong, Malaysia, Taiwan and the UK completed measures of demographic variables (age, gender, household income and highest education level) and a brief three-item health literacy scale. Results Rates of inadequate health literacy were lowest in the UK (7.0%), Australia (10.0%), Hong Kong (15.7%) and Taiwan (18.0%) samples, with higher rates in the Brazil (22.0%), Malaysia (25.0%) and China (37.0%) samples. Income was an independent predictor of health literacy levels, accounting for effects of age. Health literacy was also independently related to China national group membership. Conclusions Findings indicate non trivial levels of inadequate health literacy in samples of familial hypercholesterolemia patients. Consistent with previous research in chronic illness, inadequate health literacy is related to income as an index of health disparities. Chinese familial hypercholesterolemia patients are more likely to have high rates of inadequate health literacy independent of income. Current findings highlight the imperative of education interventions targeting familial hypercholesterolemia patients with inadequate health literacy. PMID- 29592532 TI - Thirty-Day and 5-Year Readmissions following First Psychiatric Hospitalization: A System-Level Study of Ontario's Psychiatric Care. AB - OBJECTIVE: Analyses of representative, system-level data to examine trends in short- and longer-term readmission rates for psychiatric illnesses are largely absent. The objective of this article is to examine key trends and variables with implications for inpatient care as indicated by 30-day readmission and outpatient care as reflected by readmission within 5 years. METHODS: Using OMHRS data from 2005 to 2015, patients who had their first inpatient admission were followed for 5 years to examine their subsequent 30-day and overall admission rates stratified by discharge time and diagnosis. RESULTS: The study cohort consisted of 42,280 patients. The 30-day and 5-year readmission rates for the entire cohort were 7.2% and 35.1%, respectively. Using a time course analysis of readmission for discharges in different years, both 30-day readmission and 5-year readmission rates decreased in a linear manner from 2005 to 2010, primarily because of readmission patterns for patients diagnosed with mood disorders and schizophrenia/other psychotic disorders. It was also evident that both demographic considerations such as age and gender and variables reflective of social determinants such as education level and employment were predictive of rehospitalization risk. CONCLUSIONS: The trends of decreasing readmission rates may be reflective of improvements in the quality of hospital and community-based outpatient care. Such system-level indicators warrant tracking and may inform more effective tertiary prevention. PMID- 29592533 TI - iStent inject as a reasonable alternative procedure following failed trabeculectomy? AB - PURPOSE:: The aim of this study is to assess the intraocular pressure lowering effect and the performance of the glaucoma therapy of the iStent inject in glaucoma patients with uncontrolled intraocular pressure after failed trabeculectomy. METHODS:: In this retrospective study, iStent inject implantation (Glaukos Corporation, Laguna Hills, CA, USA) was performed in 22 eyes of 21 subjects suffering from glaucoma (n = 18 primary open angle glaucoma, n = 3 pseudoexfoliation glaucoma, and n = 1 for secondary glaucoma) with an intraocular pressure above target pressure after failed trabeculectomy (mean = 9.6 +/- 8.1 years; range: 1-35 years). The intraocular pressure and the number of antiglaucomatous medication were assessed preoperatively, 1 day, 6 weeks, 3 months, 6 months, and 1 year after surgery and compared to preoperative findings (SPSS v23.0; Shapiro-Wilk test, Wilcoxon test, Friedman test). RESULTS:: The results showed a significant intraocular pressure decrease from 22.5 +/- 4.6 to 15.5 +/- 3.4 mmHg after 1 year follow-up (p = 0.012). The glaucoma therapy was 2.6 +/- 1.2 preoperatively and reduced to 2.25 +/- 1.5 number of medications after 1 year (p > 0.05). There was no significant difference in the number of medication during the whole follow-up period (1 year, p = 0.012). No significant intra- or postoperative complications were reported. CONCLUSION:: Minimal invasive glaucoma surgery (iStent inject) can offer an effective intraocular pressure reduction in advanced adult primary and secondary open angle glaucoma after failed trabeculectomy in a follow-up period of 1 year. Glaucoma therapy, however, needs to be maintained to achieve an individual target pressure and to prevent glaucoma progression. In addition, a failure rate of 27.3% makes it necessary to select carefully patients for this treatment option.

PMID- 29592534 TI - [End-of-Life Care in Intensive Care Units: Nursing strategies of family involvement at the end of life]. AB - Background: Family members of people dying in the intensive care unit (ICU) are exposed to many stress factors and they often do not experience involvement in End-of-Life (EoL) situations. For example, they criticize a low degree of participation in patients care, delayed or incomplete information and lack of privacy. Even nursing staff is facing various obstacles in EoL situations in ICUs. Aim: This study investigates strategies used by ICU nursing staff in German speaking Switzerland to increase family members participation in situations at the end of life. Method: Data was collected by conducting 12 semi-structured interviews using an approach based on Grounded Theory. A model was developed to explain nursing strategies for family involvement in EoL situations in the ICU. Conclusions: Nurses provide personal space and tranquillity for family members and allow them to be present at any time. Against this background, they support family members and enable them to say goodbye consciously to a loved one. Subsequent work should examine the effectiveness of the strategies described, particularly in terms of stress reactions displayed by family members in the aftermath of EoL situations. In practice, family members should be provided space for privacy. The entire healthcare team is recommended to identify and pursue common values and objectives. Moreover, intradisciplinary exchange and mentoring need to be encouraged. In order to prepare future nursing staff for EoL situations in the ICU, recognizing and promoting their educational skills is mandatory. PMID- 29592536 TI - ["Alone with the taboo" - The social support experienced by women with vulvar neoplasia: a qualitative study]. AB - : "Alone with the taboo" - The social support experienced by women with vulvar neoplasia: a qualitative study Abstract. BACKGROUND: Cancer of the vulva is a gynaecological disease often with relevant impact for these women's daily life. On top of the medical complications, psychological problems might arise as well, due to the impaired quality of life and the withdrawal from social life. We do not know whether and what type of support is given to these patients. AIM: The qualitative study aimed at describing how the affected women experience the support they receive from their social environment from the time of the diagnosis to six months postoperatively. METHODS: A qualitative design was used. In a secondary analysis, 20 transcribed interviews from the WOMN-PRO study were analysed by qualitative content analysis according to Mayring. RESULTS: The findings from the study resulted in four main categories: having a serious disease shows how the patients experience the diagnosis as a shock and are confronted with questions of guilt and taboos. The category feel alone was strongly represented with features of not-speaking out, not looking at it and not acting. Do it on your own features descriptions of the strategies the women use to get out of their loneliness. In experience help, it is shown that women who try to get in touch with their social environment usually receive support. CONCLUSIONS: Patients have a high demand for information concerning the disease and its possible impacts on their daily life as well as emotional and practical support from their families / partners and especially from health professionals. We recommend designating someone who acts throughout the whole treatment process as a mediator and a person of trust. PMID- 29592537 TI - Identification of the Medication Regimen Complexity Index as an Associated Factor of Nonadherence to Antiretroviral Treatment in HIV Positive Patients. AB - BACKGROUND: Multiple studies have identified a relationship between the complexity of a medication regimen and non-adherence. However, most studies in people who live with HIV (PLWH) have focused on antiretroviral use and have failed to consider the impact of other medications. OBJECTIVE: The aim of our study is to identify the Medication Regimen Complexity Index (MRCI) as an associated factor for nonadherence to antiretroviral treatment (ART). The secondary aim is to analyze the relationship between clinical and pharmacotherapeutical variables and adherence to antiretroviral treatment and to generate an adherence model. METHODS: A transversal, observational study. Patients included were PLWH over 18 years of age on active antiretroviral therapy. Patients who participated in clinical trials or who did not meet the inclusion criteria were excluded. We had studied HIV transmission mode, viral load, treatment status, number of comorbidities and complexity index as factors associated with adherence to ART. RESULTS: We included 619 patients in the study. Number of comorbidities ( p = 0.021; OR = 1.038-1.570); viral load ( p = 0.023; OR = 1.108-4.505) and MRCI ( p < 0.001; OR = 1.138-1.262) (ART and concomitant treatment) were the independent associated factors to ART nonadherence. The value of the Hosmer and Lemeshow test confirmed the validity of this model (P = 0.333). CONCLUSION: A higher MRCI was associated with non-adherence. Therefore, the regimen complexity calculation may be appropriate in daily practice for identifying patients at a higher risk of becoming non-adherent. PMID- 29592538 TI - Enoxaparin Dosing at Extremes of Weight: Literature Review and Dosing Recommendations. AB - OBJECTIVE: To review the literature on both thromboprophylaxis and treatment of venous thromboembolism (VTE) with enoxaparin in low- and high-body-weight patients and to make dosing and monitoring recommendations in these patient populations. DATA SOURCES: A search using PubMed was conducted (1995 to January 2018) using the following key words: enoxaparin, body weight, AND thromboprophylaxis, or AND treatment. Additional references were identified from a review of citations. STUDY SELECTION AND DATA EXTRACTION: Studies included examined the effect of body weight and/or body mass index (BMI) on VTE, bleeding, enoxaparin dosing, and/or anti-Xa concentrations for thromboprophylaxis and treatment-dose enoxaparin. Studies in pediatric and pregnant patients were excluded. DATA SYNTHESIS: Optimal enoxaparin dosing strategies for VTE prophylaxis and treatment for patients at extremes of weight have not yet been elucidated by clinical trials; however, data suggest that standard dosing regimens may not be appropriate in these patients. Relevance to Patient Care and Clinical Practice: This review provides a thorough discussion on both thromboprophylaxis and treatment of VTE with enoxaparin in low- and high-body weight patients. It includes dosing recommendations to guide clinicians caring for these patient populations. CONCLUSIONS: Patients at extremes of weight require special consideration to determine appropriate enoxaparin doses. Specifically, low-body-weight patients may benefit from 30 mg subcutaneously daily for VTE prophylaxis, and standard weight-based dosing for VTE treatment. Conversely, in patients with BMIs >=40 kg/m2, 40 mg subcutaneously twice daily is recommended, with consideration for higher doses in patients with BMIs >=50 kg/m2.

AB - OBJECTIVE: To determine the pharmacological treatment methods available to anemic Jehovah's Witnesses (JW). DATA SOURCES: MEDLINE and PubMed were searched from inception through February 2018 using the search terms Jehovah's Witnesses, treatment, erythropoietin, hemoglobin-based oxygen carrier, Sanguinate, Hemopure, bleeding, and anemia. STUDY SELECTION AND DATA EXTRACTION: All clinical trials, cohort studies, case-control studies, and observational trials involving pharmacotherapy in anemic JW patients were evaluated. Case reports and bibliographies were also analyzed for inclusion. DATA SYNTHESIS: Two studies involving the use of erythropoietin (EPO) and one study involving recombinant factor VIIa were included. Information was also included from other pharmacotherapeutic modalities that had case report data only. Current published evidence is limited with regard to evidence-based management of JW patients. High dose EPO, intravenous iron supplementation, and hemostatic agents have demonstrated good clinical outcomes in case reports. EPO doses as high as 40 000 units daily have been advocated by some experts; however, pharmacokinetic studies do not support dose-dependent effects. Hemoglobin-based oxygen carriers (HBOCs) are currently not Food and Drug Administration approved. They are available through expanded access programs and may represent a lifesaving modality in the setting of severe anemia. CONCLUSIONS: There are currently not enough data to make definitive recommendations on the use of pharmacological agents to treat severe anemia in the JW population. Further evidence utilizing EPO and HBOCs will be beneficial to guide therapy. PMID- 29592540 TI - Reported Problems and Adherence in Using Asthma Medications Among Adolescents and Their Caregivers. AB - BACKGROUND: Many factors affect youth adherence to asthma medications. Better understanding of the relationship between problems reported by youth in using asthma medications, self-efficacy, outcome expectations, and adherence is needed. OBJECTIVE: The study examined the relationship between youth and caregiver problems in using asthma medications, asthma management self-efficacy, outcome expectations, and youth- and caregiver-reported adherence to asthma controller medications. METHODS: Adolescents with persistent asthma and their caregivers were recruited at 4 pediatric practices. Youth were interviewed after their medical visit while caregivers completed a questionnaire. Multivariable linear regression was used to analyze the data. RESULTS: Of 359 participating youth, 319 were on controller medications. Youth reported 60% average adherence, whereas caregivers reported 69%. Youth who reported difficulty using their inhaler correctly and youth who reported difficulty remembering to take their medications were significantly less likely to be adherent. Caregivers who reported that it was hard to remember when to give the asthma medications were significantly less likely to report their child being adherent. Both youth and caregivers with higher outcome expectations were significantly more likely to self-report being adherent. CONCLUSIONS: Pharmacists and other health care providers should consider asking youth and caregivers about problems in using asthma medications, self-efficacy in managing asthma, and outcome expectations for following treatment regimens, so that they can help youth overcome difficulties they might have in managing their asthma.

Allocation of resources to reproduction (eggs) and survival (life span) should maximize reproductive success, but stochasticity in the number of hosts encountered precludes an exact match of allocation with reproductive opportunity. We study optimal egg loads using a general model for pro-ovigenic parasitoids (which only mature eggs before adult life) and a dynamic programming model for synovigenic parasitoids (which can mature additional eggs during adult life). We find that stochasticity has a major effect on optimal egg loads and that the patchy distribution of hosts is the major source of stochasticity in reproductive opportunities. In a stochastic world, the further "relative habitat quality" (expected number of oviposition opportunities gained by reducing reproductive investment by one egg) is below unity (as we argue it generally is), the more the optimal egg load exceeds the expected number of hosts. In unusually rich environments, however, stochasticity decreases optimal egg loads. Although synovigenic parasitoids can adjust to the conditions they encounter, they too have to invest for an uncertain future. Because they can replenish their egg supply throughout life, the incidence of egg limitation is even lower than in pro-ovigenic parasitoids.

AB - The legume-rhizobium symbiosis is an ideal model for studying the factors that limit the evolution of microbial mutualists into parasites. Legumes are unable to consistently recognize parasitic rhizobia that, once established inside plant cells, use plant resources for their own reproduction rather than for N2 fixation. Evolution of parasitism in rhizobia, driven partly by competition among multiple rhizobial strains infecting the same plant, may be countered by postinfection legume sanctions. Both the biochemical options for rhizobial cheating and the evolutionary effect of legume sanctions depend on differences in rhizobial life history associated with nodule type. In legumes with determinate nodule growth, rhizobia typically retain the ability to reproduce after differentiating into N2-fixing bacteroids. Sanctions against individual bacteroids (e.g., acid hydrolases) would therefore select for cooperative rhizobia. In nodules with indeterminate growth, bacteroids generally lose the ability to reproduce, so legume sanctions against bacteroids would have no effect on rhizobial evolution. Whole-nodule sanctions (e.g., decreased nodule O2 permeability) could be effective, via kin selection of undifferentiated rhizobia that persist in indeterminate nodules and replenish soil populations after nodule senescence. Mixed nodules could reduce the effectiveness of whole-nodule sanctions. The frequency of mixed nodules under field conditions is unknown. PMID- 29592543 TI - The Origin of Interspecific Genomic Incompatibility via Gene Duplication. AB - One of the great unsolved mysteries of evolutionary biology concerns the genetic mechanisms underlying the origin of genomic incompatibilities between species. Two prevailing thoughts are that such incompatibilities often result from epistatically interacting genes that act as loss-of-function alleles in hybrid backgrounds or from chromosomal rearrangements that result in mis-segregation during meiosis in hybrids. However, it is unclear how genes that cause a radical breakdown in hybrids arise without reducing fitness within species, and numerous cases of speciation appear to be unassociated with obvious chromosomal rearrangements. Here we suggest that duplicate genes, and more generally any kind of genomic redundancies, provide a powerful substrate for the origin of genomic incompatibilities in isolated populations. The divergent resolution of genomic redundancies, such that one population loses function from one copy while the second population loses function from a second copy at a different chromosomal location, leads to chromosomal repatterning such that gametes produced by hybrid individuals can be completely lacking in functional genes for a duplicate pair. Under this model, incompatibility factors accumulate with essentially no loss of fitness within populations as postulated under the Bateson-Dobzhansky-Muller (BDM) model of speciation and despite the fact that they arise from degenerative mutations. However, unlike the situation often envisioned under the BDM model, no change in the mode of gene action in hybrid backgrounds need be invoked. The plausibility of this model derives from a number of recent observations, including the fact that most genomes harbor substantial numbers of gene duplicates whose turnover is common and ongoing process and the fact that many genes have complex regulatory regions that facilitate their divergent resolution in sister taxa. PMID- 29592544 TI - Specialized Feeding Behavior Influences Both Ecological Specialization and Assortative Mating in Sympatric Host Races of Pea Aphids. AB - Not only is ecological specialization a defining feature of much of Earth's biological diversity, the evolution of specialization may also play a central role in generating diversity by facilitating speciation. To understand how ecological specialization evolves, we must know the particular characters that cause organisms to be specialized. For example, most theories of specialization in herbivorous insects emphasize physiological trade-offs in response to toxic plant chemicals. However, even in herbivores, it is likely that other characters are also involved in resource specialization. Knowing the causes of ecological specialization is also crucial for linking specialization to speciation. When the same character(s) that cause specialization also influence assortative mating, speciation may occur particularly rapidly because specialization and reproductive isolation become coupled in a positive feedback that speeds the evolution of both. Indeed, a central hypothesis in the study of ecological speciation is that specialization in recently diverged taxa may often be due to characters that also produce assortative mating. We test this hypothesis by evaluating the causes of ecological specialization among host-associated populations of an herbivorous insect, the pea aphid (Acyrthosiphon pisum). These populations are highly specialized on different host plants (alfalfa or clover; "alternate hosts"), and the races are partially reproductively isolated. Here, we identify key characters responsible for host plant specialization. Our results suggest that the major proximal determinant of host specialization is the behavioral acceptance of a plant rather than the toxicity of the food source. Pea aphids rapidly assess alfalfa and clover and reject the alternate host based on chemical cues that are perceived before the initiation of feeding. This rapid behavioral rejection of the alternate host by a given race has two consequences. First, unrestrained aphids quickly leave the alternate host and search for other plants. Because pea aphids mate on their host plants, divergence in host acceptance among ecologically specialized races leads to congregation on the favored host. This results in de facto assortative mating when sexual forms are produced in late summer. Second, specialized aphids that are held on the alternate host will not feed in a 7.2-h trial, even in the face of starvation. Thus, a complex trait, behavioral acceptance of a plant as host, influences both reproductive isolation (through host-associated assortative mating) and ecological specialization (because of low nutritional uptake on the alternate host). This dual influence of feeding behavior on both assortative mating and resource specialization is central to the maintenance of these divergent races, and it may also have been involved in their origin. PMID- 29592545 TI - Sex Allocation and Reproductive Success in the Andromonoecious Perennial Solanum carolinense (Solanaceae). II. Paternity and Functional Gender. AB - According to Bateman's principle, male fitness in entomophilous plant species should be limited by mating opportunity, which is influenced by the size or number of flowers. We determined male-specific fitness consequences of floral phenotype in andromonoecious Solanum carolinense, examined the relationship between male and female reproductive success within plants, and evaluated the distribution of functional gender among plants. A maximum likelihood-based paternity analysis, based on multilocus allozyme phenotypes of parents and offspring from four experimental plots, was used to determine male reproductive success and its relationship to floral phenotype. Male success was enhanced by an increase in the proportion of male flowers produced but not by an increase in total flower number, even though all flowers contain male parts. Larger flower size increased male success in only one plot. Male and female reproductive success were negatively correlated, and plants varied in functional gender from completely female to completely male. This gender specialization may occur because hermaphroditic and male flowers differ in their ability to contribute to male and female success. Although sex allocation theory predicts a positive relationship between the size or number of plant parts and reproductive success, this study indicates that aspects of floral morphology that affect gender specialization should also be considered. PMID- 29592546 TI - Begging and Parental Care in Relation to Offspring Need and Condition in the Barn Swallow (Hirundo rustica). AB - Parents are selected to maximize their fitness by allocating care among their progeny in relation to the differential reproductive value of offspring. Nestlings have been hypothesized to signal need for parental care reliably through their begging behavior, but offspring condition as reflected by their reproductive value may likewise affect begging and hence provisioning. We assessed the relative importance of need and condition in determining begging behavior and feeding rate of nestling barn swallows (Hirundo rustica) through short-term starvation, a challenge to their immune system with a foreign antigen negatively affecting condition, and brood size manipulation. Food deprivation but not condition or brood size manipulation increased nestling begging rate. Parents fed offspring depending on both need and condition but only when feeding broods that were reduced or of normal size. In enlarged broods, offspring received less food per capita than in reduced broods, and parents did not discriminate among nestlings relative to their need or condition. Thus, nestlings signal their need by increased solicitation. Parents allocate food to offspring dependent on both need and condition, with these effects depending on parental workload as determined by experimental brood size. PMID- 29592547 TI - Measuring and Using Skew in the Study of Social Behavior and Evolution. AB - Unequal distribution of benefits from cooperation is a fundamental feature of social behavior, and many quantitative measures of this skew have been proposed. Overall group size and productivity affect each of the measures somewhat differently depending on their formulation. Some of the differences are due to whether the index is intended to measure skew relative to a random distribution or relative to the maximum possible skew. Sampling errors, however, will tend to make smaller and less productive groups seem more skewed than they actually are. Differential survival or residence times of group members add a second factor that can result in skew independent of behavioral mechanisms. Thus, significant biases can result in indices that do not account for random processes or differential survival within groups. Seven published skew indices plus a new index (B) that combines observed variance with the expected binomial variance were tested across simulations that compared groups varying in resource distribution probabilities, size, or productivity. Only the B index always avoided error through correctly adjusting for group size, productivity, and differential residence times. Thus, the B index has the best potential to be a benchmark value that can be used for identifying evolutionary patterns in social behavior, both across and especially within species. Although skew indices have been applied mostly to shared reproduction, the B index is suitable to any situation where group members divide benefits. Skew indices potentially can identify and test evolutionary scenarios across a wide range of behavioral interactions, such as dominance hierarchies, information exchange, and parental care. PMID- 29592580 TI - Studies of Adaptive Radiation Using Model Microbial Systems. AB - Adaptive radiation is a fundamental process in the evolution of biodiversity. The effects of seasonality, resource partitioning, and spatial heterogeneity have been examined experimentally using evolving populations of microbes. In all environmental conditions examined, ecological interactions have large effect on the likelihood and outcome of adaptive radiation. Adaptive radiation in seasonal environments can arise because of demographic trade-offs and excretion of metabolites. Resource partitioning can occur even in the absence of temporal or spatial heterogeneity. Spatial heterogeneity arising via growth is sufficient to generate microenvironments and subsequent adaptive radiation. However, ecological interactions maintaining diversity can be sensitive to slight alterations of the environmental conditions. Laboratory populations of microbes are ideal model systems to test the factors essential for adaptive radiation. PMID- 29592581 TI - Character Shifts of Prey Species That Share Predators. AB - This article uses several models to explore the potential indirect evolutionary interaction between two prey species that share one or more predator species. It asks how the antipredator adaptations of a focal prey species are likely to evolve following the introduction of a second prey species that shares one or more of the same predator species. The interactions are represented by differential equation models of homogeneous populations, and evolutionary change occurs in a single quantitative trait within each prey species. Models differ in assumptions about the number of predator types, the costs of antipredator traits, and in how predator and prey traits combine to determine a per capita capture rate. Parallel change in the antipredator characteristics of two species usually occurs when the general risk of predation is changed by the introduction of the second prey. This may be a parallel increase or decrease, depending on whether the ecological interaction is apparent competition or apparent mutualism. Divergence in trait values is most often associated with the presence of two or more distinct types of predators with some form of trade-off in the prey's ability to avoid different predators. Divergence may also occur with a single predator type, when two or more strategies exist for reducing predation risk. Convergence is a possible outcome when there are two or more predator types. Coevolution may also produce trait and population cycles in models, and the nature of character displacement is often changed markedly by such instability. The limited evidence for evolutionary indirect effects mediated by shared predation is reviewed. Possible reasons for the disparity between theory and observation are discussed. PMID- 29592582 TI - Reversal of Mutualism as a Mechanism for Adaptive Radiation in Yucca Moths. AB - Species interactions are a major source of adaptive radiation. In mutualisms, such diversification can take the form of evolution of parasites that exploit the resources needed for maintenance of the mutualism. Mutualistic associations often have associated parasitic species, and in some cases, parasitic species have indeed evolved from the mutualists. For example, obligate mutualisms, such as those involving seed-eating pollinators, have on a few occasions given rise to nonmutualist species. These systems are relatively simple and provide models for identifying factors that facilitate the stable reversal of a mutualistic interaction. We used ecological data in a phylogenetic framework to analyze the origins of two nonmutualist cheater yucca moths. Phylogenetic analysis suggests that the evolution of cheating may be preceded by a change in oviposition behavior. Two different modes of oviposition among moth species cause density dependent moth egg mortality through flower abscission in one case (locule ovipositing species) but density-independent mortality in the other (superficially ovipositing species). A mtDNA-based phylogeny indicated that cheating and superficial oviposition have evolved twice each and that the cheater clades are sisters to the superficially ovipositing species clades. Consideration of the fitness consequences of two trait changes-loss of pollination and phenological delay in oviposition-in which cheaters have diverged from ancestral pollinators suggest that the shift to oviposition into fruit may have occurred first and that loss of pollination behavior was a secondary event. We suggest that secondary coexistence of two pollinator species of opposite oviposition modes may facilitate the shift to fruit oviposition and cheating and that this is applicable in the best documented of the cheater yucca moths. Superficially ovipositing species suffer dual sources of egg mortality when in coexistence with locule-ovipositing species. Shift to fruit oviposition under this circumstance can be facilitated by access to a seed resource not available to the copollinator, preadaptations in ovipositor morphology, and pollinator phenology late relative to the copollinator. Thus the adaptive radiation of nonmutualists from mutualists may have taken place in specific ecological contexts through few trait changes, and the reversal of mutualism would be a by-product of a shift to reliance on a previously inaccessible seed resource. PMID- 29592583 TI - Evolutionary Branching and Sympatric Speciation Caused by Different Types of Ecological Interactions. AB - Evolutionary branching occurs when frequency-dependent selection splits a phenotypically monomorphic population into two distinct phenotypic clusters. A prerequisite for evolutionary branching is that directional selection drives the population toward a fitness minimum in phenotype space. This article demonstrates that selection regimes leading to evolutionary branching readily arise from a wide variety of different ecological interactions within and between species. We use classical ecological models for symmetric and asymmetric competition, for mutualism, and for predator-prey interactions to describe evolving populations with continuously varying characters. For these models, we investigate the ecological and evolutionary conditions that allow for evolutionary branching and establish that branching is a generic and robust phenomenon. Evolutionary branching becomes a model for sympatric speciation when population genetics and mating mechanisms are incorporated into ecological models. In sexual populations with random mating, the continual production of intermediate phenotypes from two incipient branches prevents evolutionary branching. In contrast, when mating is assortative for the ecological characters under study, evolutionary branching is possible in sexual populations and can lead to speciation. Therefore, we also study the evolution of assortative mating as a quantitative character. We show that evolution under branching conditions selects for assortativeness and thus allows sexual populations to escape from fitness minima. We conclude that evolutionary branching offers a general basis for understanding adaptive speciation and radiation under a wide range of different ecological conditions. PMID- 29592584 TI - Comparative Analysis of Character Displacement and Spatial Adaptations as Illustrated by the Evolution of Dalechampia Blossoms. AB - We describe a phylogenetic and spatial approach to the comparative study of character displacement and other coevolutionary phenomena. The method is developed as an in-depth study of blossom morphology in 37 populations of the Neotropical vine Dalechampia scandens. We test the hypothesis that among population variation in blossom morphology is due largely to local adaptation to avoid competition from other species of Dalechampia that utilize the same restricted set of pollinators. Because direct phylogenetic and historical information are unavailable for these populations, we develop a novel comparative method for the study of adaptation to a spatially distributed selective factor in spatially correlated populations. In addition to providing spatially, or phylogenetically, corrected estimates of selective effects, the method assesses the local specificity of adaptations. We find evidence for moderately strong local specificity of adaptation among our populations, and furthermore we find that the effects of putative competitors are in accordance with predictions from a hypothesis of character displacement. However, sympatry or allopatry explains only 10%-20% of the interpopulation variation in blossom morphology, and we therefore cannot exclude the possibility that some other selective factors are major determinants of the variation. PMID- 29592585 TI - Individual Value Clarification Methods Based on Conjoint Analysis: A Systematic Review of Common Practice in Task Design, Statistical Analysis, and Presentation of Results. AB - BACKGROUND: There is an increased practice of using value clarification exercises in decision aids that aim to improve shared decision making. Our objective was to systematically review to which extent conjoint analysis (CA) is used to elicit individual preferences for clinical decision support. We aimed to identify the common practices in the selection of attributes and levels, the design of choice tasks, and the instrument used to clarify values. METHODS: We searched Scopus, PubMed, PsycINFO, and Web of Science to identify studies that developed a CA exercise to elicit individual patients' preferences related to medical decisions. We extracted data on the above-mentioned items. RESULTS: Eight studies were identified. Studies included a fixed set of 4-8 attributes, which were predetermined by interviews, focus groups, or literature review. All studies used adaptive conjoint analysis (ACA) for their choice task design. Furthermore, all studies provided patients with their preference results in real time, although the type of outcome that was presented to patients differed (attribute importance or treatment scores). Among studies, patients were positive about the ACA exercise, whereas time and effort needed from clinicians to facilitate the ACA exercise were identified as the main barriers to implementation. DISCUSSION: There is only limited published use of CA exercises in shared decision making. Most studies resembled each other in design choices made, but patients received different feedback among studies. Further research should focus on the feedback patients want to receive and how the CA results fit within the patient-physician dialogue. PMID- 29592605 TI - A Systematic Review of Caregiver-Implemented Mealtime Interventions for Children With Autism Spectrum Disorder. AB - Children with autism spectrum disorder (ASD) frequently have difficult mealtimes. A systematic review analyzed current evidence relevant to occupational therapy (OT) and mealtime interventions (a) for children with ASD, (b) occurring in the natural contexts, and (c) with parents/caregivers as interventionists. Database search identified 13 relevant articles. Each article was reviewed for practicality of implementation through a modified Feasibility, Appropriateness, Meaningfulness and Effectiveness (FAME) scale and for quality of research design using three measures specifically designed for single-case experimental design research. The majority of articles reviewed demonstrated rigorous research design with strong evidence for the effectiveness of caregiver-implemented interventions. Six intervention techniques were identified, with all studies using a reinforcement strategy and at least one other technique. This review identifies evidence-based practices for OTs to support children with ASD and their families within the natural co-occupation of mealtimes. Effective techniques and recommendations for practice are included. PMID- 29592634 TI - Risk Factors Associated With Peripheral Neuropathy in Heart Failure Patients Candidates for Transplantation. AB - INTRODUCTION: Peripheral neuropathy can affect patients with heart failure, though its prevalence is unknown. After heart transplantation, it can influence the postoperative course and quality of life, but screening for neuromuscular disease is not routinely performed. OBJECTIVE: The aim of this study was to identify the factors associated with neuropathy in a population of patients with heart failure who are candidates for heart transplantation. STUDY DESIGN: Data regarding patients' clinical history, including recent hospitalizations, were collected. All patients underwent a complete neurological examination and a neurophysiological protocol including nerve conduction studies and concentric needle electromyography. RESULTS: Thirty-two patients were included in the study, and neuropathy was diagnosed in 10 (31.3%). Neuropathy was associated with the number of admissions ( P = .023; odds ratio [OR]: 1.96) and the total number of days of hospitalization in the year prior to inclusion in the study ( P = .010; OR: 1.03). The majority of hospitalizations occurred in the step-down unit (85%), with acute heart failure the leading cause of admission (42%). CONCLUSIONS: This study shows that neuropathy is frequent in patients with advanced heart failure and that hospitalization for cardiac care, also in the absence of intensive care, is a marker of high risk of neurologic damage. These data can help physicians in selecting and managing candidates for transplantation and can guide decisions on the best immunosuppressive regimen or rehabilitation strategy. PMID- 29592635 TI - How Inaccurate Metrics Hide the True Potential for Organ Donation in the United States. AB - BACKGROUND: There is a discrepancy between the reported increase in donor conversion rates and the number of organs available for transplant. METHODS: Secondary analysis of data obtained from the Scientific Registry of Transplant Recipients from January 2003 through December 2015 was performed. The primary outcomes were the (1) number of brain-dead donors from whom solid organs were recovered and (2) number of the organs transplanted. Descriptive statistics and growth plots were used to examine the trajectory of organ donation, recovery, and transplantation outcomes over the 11-year period. RESULTS: From 2003 to 2006, the number of brain-dead donors increased from 6187 to 7375, remaining relatively stable at approximately 7200 thereafter. The average eligible deaths per organ procurement organization dropped from 182.7 (standard deviation [SD]: 131.3) in 2003 to 149.3 (SD: 111.4) in 2015. This suggests a total of 12 493 unrealized potential donors (2006-2015). CONCLUSIONS: Since 2006, a steady decline in the number of donor-eligible deaths was reported. In 2003, the reported eligible deaths was 11 326. This number peaked in 2004 at 11 346, tumbling to 9781 eligible donors in 2015, despite a 9% increase in the US population. From 2006 to 2015, the data indicate an artificial depression and underestimation of the true potential of brain-dead donors in the United States of conservatively 12 493 donors or 39 728 missing organs. New metrics providing objective but verifiable counts of the donor pool are needed. PMID- 29592637 TI - To Have Seen or Not to Have Seen: A Look at Rensink, O'Regan, and Clark (1997).

The goal of this short article is to describe my serendipitous encounter with this brain signal in 1993-1994 and to briefly review the operation of the underlying error-monitoring system. Recent work suggests that the ERN reflects an internal comparison, by the anterior cingulate cortex, of two signals: an unconscious representation of the ongoing action and a conscious representation of the intended one. PMID- 29592638 TI - Revisiting Our Reappraisal of the (Surprisingly Few) Benefits of High Self Esteem. AB - Our 2003 article clashed with conventional wisdom by concluding that high self esteem has only a couple of benefits, notably high initiative (based on trusting one's own judgment) and feeling good. Its high citation rate reflects not only the novel conclusions but also widespread interest in self-esteem both among researchers and in the broader society. Psychology may have lost some credibility by advocating efforts to raise self-esteem that were based on correlational evidence, which may be a salutary lesson for the field. There is still much to learn about self-esteem, but future work can improve by noting weaknesses in self report data and correcting for confounds. PMID- 29592639 TI - Sexual and Emotional Infidelity: Evolved Gender Differences in Jealousy Prove Robust and Replicable. AB - Infidelity poses threats to high-investment mating relationships. Because of gender differences in some aspects of reproductive biology, such as internal female fertilization, the nature of these threats differs for men and women. Men, but not women, for example, have recurrently faced the problem of uncertainty in their genetic parenthood. Jealousy is an emotion hypothesized to have evolved to combat these threats. The 1992 article Sex Differences in Jealousy: Evolution, Physiology, and Psychology reported three empirical studies using two different methods, forced-choice and physiological experiments. Results supported the evolution-based hypotheses. The article became highly cited for several reasons. It elevated the status of jealousy as an important emotion to be explained by any comprehensive theory of human emotions. Subsequent meta-analyses robustly supported the evolutionary hypotheses. Moreover, the work supported the evolutionary meta-theory of gender differences, which posits differences only in domains in which the sexes have recurrently faced distinct adaptive problems. It also heralded the newly emerging field of evolutionary psychology as a useful perspective that possesses the scientific virtues of testability, falsifiability, and heuristic value in discovering previously unknown psychological phenomena.

AB - This introduction to the special symposium on the top 30 most-cited articles in APS journals considers some of the factors that lead some articles to have huge impact. What is it that scientists can do to achieve the greatest impact for their work? PMID- 29592642 TI - Happiest People Revisited. AB - In a past Psychological Science article, Diener and Seligman (2002) explored the characteristics of extremely happy individuals and found that strong social relationships characterized the entire group. The study was popular, perhaps because the authors focused on the very happiest people, not merely on correlations across the entire spectrum of subjective well-being. In the current study, we replicated and extended the earlier paper here by examining, in a world sample, the differences between the happiest individuals and unhappy and averagely happy people. We largely replicated earlier findings; basic need fulfillment and social resources were two ingredients for high subjective well being. Replicating and extending the earlier findings, we found that, compared with the averagely happy people, the happiest people were more likely to come from societies high in subjective well-being and social capital. To achieve very high happiness, it is helpful not only to have desirable personal circumstances, but also to live in a prosperous happy society with strong social support. As in the original study, although a few characteristics seemed virtually necessary for subjective well-being (SWB), no characteristic guaranteed it. We also uncovered variables separating the groups that might be outcomes of SWB, for example, helping others, exercising, and not smoking.

This article was both one of the first publications to provide empirical support for hypotheses based on the broaden-and build theory of positive emotions and a product of the genesis of positive psychology. We highlight empirical and theoretical advancements in the scientific understanding of upward spiral dynamics associated with positive emotions, with particular focus on the new upward spiral theory of lifestyle change. We conclude by encouraging deeper and more rigorous tests of the prospective and reciprocal relations associated with positive emotions. Such progress is needed to better inform translations and applications to improve people's health and well-being. PMID- 29592644 TI - Well-Being With Soul: Science in Pursuit of Human Potential.

AB - Richard Schmidt and I titled our article "New Conceptualizations of Practice: Common Principles in Three Paradigms Suggest New Concepts for Training" to reflect our view that prevailing ideas about how to optimize teaching, learning, and practicing were, in our words, "at best incomplete, and at worst incorrect." We argued that teachers and trainers were susceptible to being misled by two commonsense assumptions-namely, that procedures that enhance performance during training are the procedures of choice and that the context of training needs to match in detail the posttraining context that is the target of training. A variety of then-recent experimental findings challenged both assumptions and demonstrated, in particular, that procedures posing certain difficulties and appearing to slow the rate of learning often enhanced long-term retention and transfer of to-be-learned skills and knowledge. Given the parallel nature of such findings for both motor and verbal learning, we concluded that principles of considerable generality could be deduced to upgrade teaching and training. PMID- 29592646 TI - Beyond Money: Progress on an Economy of Well-Being. AB - In our 2004 "Beyond Money" article, we argued that national accounts of psychological and subjective well-being should complement the economic indicators that frequently guide policy decisions. We claimed that economic indicators fail to reflect important aspects of quality of life that well-being indicators capture. Since the time of our article, progress has been made, and scores of nations have used some forms of well-being measures. The National Academy of Sciences of the United States and the Organization for Economic Cooperation and Development both issued reports on accounts of well-being. Researchers have pointed to policies that are supported by the findings, such as environmental and economic policies. The emergence of "big data" has opened major new pathways for measuring well-being in inexpensive, unobtrusive, and nonreactive fashion. Psychological researchers now need to create superordinate combinations of subjective and objective measures of well-being to study the impact of the policies they advocate. The accounts can serve as a lever for convincing policymakers to enact policies that increase human flourishing. PMID- 29592647 TI - Reflections on the Resurgence of Interest in the Testing Effect. AB - We discuss the findings from our 2006 article in Psychological Science on the testing effect and describe how the project arose. The testing effect (or retrieval-practice effect) was first reported in the experimental literature about a century before our article was published, and the effect had been replicated (and sometimes discovered anew) many times over the years. Our experiments used prose materials (unlike most prior research) and produced a more powerful effect than prior research even though we used a conservative control condition for comparison. In our discussion, we drew out possible implications for educational practice. We also reported that students in the experiment could not predict the effect; this lack of metacognitive awareness represented a new finding in this context. In a companion article the same year, we provided an historical review of the testing effect. We believe the synergistic effect of the two articles accounts in part for the resurgence in interest in this phenomenon and its application in educational settings.

However, cognitive assessment instruments, exercise protocols (including type of exercise, length, and intensity of exercise programs), and subject-selection criteria differed widely. Our meta-analysis enabled us to examine both the main question under study-exercise effects on cognition-and potential moderators of this effect. Several interesting findings, which are briefly detailed in the present article, were revealed by our analyses. The current article also examines where the literature has gone since our 2003 article. PMID- 29592651 TI - The Scientific Pursuit of Happiness. AB - We review the history of happiness research that gave rise to our 1995 review. We then summarize-and update with a quick synopsis of more recent research-each of our conclusions regarding the associations of subjective well-being with age, gender, income, personal traits, social support, and religious engagement. Finally, we briefly review new research on the benefits of happiness, and of happiness interventions at both individual and national levels. PMID- 29592652 TI - The Strength Model of Self-Regulation: Conclusions From the Second Decade of Willpower Research. AB - The strength model of self-regulation uses a muscle analogy to explain patterns of ego depletion, conservation of willpower, and improved performance after frequent exercise. Our 2007 overview of the literature has been well cited, presumably because of the phenomenon's importance to theories of selfhood and a wide assortment of applied contexts, including problem behaviors. Some researchers have put forward rival theoretical accounts, and others have questioned the existence of the phenomenon. The weight of evidence continues to support the usefulness of the strength model, albeit amid continuing updates and revisions. PMID- 29592653 TI - The Constructive, Destructive, and Reconstructive Power of Social Norms: Reprise. AB - The influence of social norms on behavior has been a longstanding storyline within social psychology. Our 2007 Psychological Science publication presented a new rendition of this classic telling. The reported field experiment showed that social norms could be leveraged to promote residential energy conservation, but importantly, the descriptive norm was shown to increase consumption for low consuming households. This potential destructive effect of social norms was eliminated with the addition of an injunctive message of social approval for using less energy. The article is among the 30 most-cited articles across all APS publications, which we attribute to our methodology, which measured real behavior in a large-scale field experiment and to several circumstances associated with the timing of the work. The article coincided with the explosion of social media, the emergence of behavioral economics, and a heightened level of concern about climate change. These contemporaneous activities set the stage for our work and for its high degree of citation. PMID- 29592654 TI - Working Memory and Executive Attention: A Revisit. AB - In this follow-up to my 2002 article on working memory capacity, fluid intelligence, and executive attention in Current Directions in Psychological Science, I review even more evidence supporting the idea that the ability to control one's attention (i.e., executive attention) is important to working memory and fluid intelligence. I now argue that working memory tasks reflect primarily the maintenance of information, whereas fluid intelligence tests reflect primarily the ability to disengage from recently attended and no longer useful information. I also point out some conclusions in the 2002 article that now appear to be wrong. PMID- 29592655 TI - The Error-Related Negativity. AB - We look back on the events surrounding the genesis of our 1993 article on the error-related negativity (ERN), a component of the event-related brain potential that accompanies errors in the performance of speeded-response tasks. Our reminiscences focus on the personal friendships, intellectual influences, and chance occurrences that shaped the article. To put our work in historical context, we consider subsequent trends in neuroimaging, computational modeling, and psychiatry that gave the ERN high visibility and contributed to the longevity of its scientific interest. PMID- 29592656 TI - Revisiting "Most People Are Happy"-And Discovering When They Are Not. AB - In our 1996 article, "Most People are Happy," we presented evidence showing that the majority of humans are above neutral in happiness. The article was popular perhaps for several reasons. First, we shed light on the ubiquity of positive or pleasant emotions, whereas previously many scholars had focused on negative or unpleasant ones. Second, our article may have received attention because, as we showed, most people believe that humans are much less happy than they actually are. Thus, our article provided an impetus for understanding the role of positive emotions as well as illuminating an important aspect of human happiness-the fact that happiness is not unusual but may be the default condition. In the current article, we review evidence from the first representative sample of humanity, the Gallup World Poll, and include many more nations that are very poor and troubled. We find that the majority of people are above neutral in affect balance but not life satisfaction. Furthermore, there are extremely bad life circumstances in which most people are below neutral in affect balance as well. This suggests that one explanation for most people's happiness is that most societies, but not all, can meet enough human needs that they provide the conditions for human happiness. Finally, our findings suggest that human happiness is not just in our heads or genes but is also influenced by personal and societal circumstances. PMID- 29592657 TI - Toward a Psychology of Human Agency: Pathways and Reflections. AB - Social cognitive theory is founded on an agentic perspective. This article reviews the core features of human agency and the individual, proxy, and collective forms in which it is exercised. Agency operates through a triadic codetermination process of causation. Knowledge from this line of theorizing is widely applied to effect individual and social change, including worldwide applications that address some of the most urgent global problems. PMID- 29592658 TI - In Vitro Antibacterial Evaluation of Terminalia chebula as an Alternative of Antibiotics against Bovine Subclinical Mastitis. AB - The extent of subclinical mastitis in three breeds of cattle, Kankrej, Gir, and Crossbred, was performed at cattle farms in Anand town of Gujarat State, India. The prevalence of subclinical mastitis in crossbred cattle was higher compared to local breed of cattle. Causative agents identified using 16S rDNA polymerase chain reaction (PCR)-based molecular method were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Bacillus megaterium. In vitro antibacterial activity of ethyl acetate extract of plant Terminalia chebula (Combretaceae) was checked by agar well diffusion method against four isolated and molecularly identified microorganisms. Ethyl acetate extract shows antimicrobial activity with varying magnitudes against all identified isolates. Among the three different concentrations, 500 ug/mL conc. of extract is as effective as that of standard amoxicillin. In vitro results support the use of plant extract from T. chebula as an alternative to antibiotics therapy against bovine subclinical mastitis. PMID- 29592765 TI - Alternative surgical procedure for treating superior vena cava syndrome in a hemodialysis patient. AB - BACKGROUND: The incidence of superior vena cava syndrome has been increasing in hemodialysis patients with the widespread use of dialysis catheters. Although endovascular intervention remains the primary choice for treatment, the long-term patency rate is not optimistic. Occlusive lesions are often encountered that cannot be opened using this intervention. Therefore, we chose to present this case involving a pericardial patch used to reconstruct the superior vena cava in the treatment of catheter-associated chronic superior vena cava occlusion. METHODS: Here, we report a case of facial swelling and severe bilateral pleural effusion secondary to superior vena cava occlusion in a 41-year-old woman. An endovascular venous intervention was attempted initially but failed. Finally, we adopted a procedure using the pericardium as a patch to reconstruct the superior vena cava, maintaining most of the original anatomical structure. RESULTS: This patient's facial swelling and bilateral pleural effusion disappeared after the operation. In addition, her symptoms of coughing and dyspnea were relieved. The Brescia-Cimino fistula in her left forearm functioned well. CONCLUSION: The use of a pericardial patch to reconstruct the superior vena cava is a reliable approach in patients who are not candidates for endovascular treatment. PMID- 29592766 TI - Surface contamination of counting tools after mock dispensing of cyclophosphamide in a simulated outpatient pharmacy. AB - PURPOSE: The primary aim was to determine if dispensing of cyclophosphamide tablets resulted in accumulated residue on pharmacy counting tools during a simulated outpatient dispensing process. Secondary objectives included determining if cyclophosphamide contamination exceeded a defined threshold level of 1 ng/cm2 and if a larger number of prescriptions dispensed resulted in increased contamination. METHODS: Mock prescriptions of 40 cyclophosphamide 50 mg tablets were counted on clean trays in three scenarios using a simulated outpatient pharmacy after assaying five cleaned trays as controls. The three scenarios consisted of five simulated dispensings of one, three, or six prescriptions dispensed per scenario. Wipe samples of trays and spatulas were collected and assayed for all trays, including the five clean trays used as controls. Contamination was defined as an assayed cyclophosphamide level at or above 0.001 ng/cm2 and levels above 1 ng/cm2 were considered sufficient to cause risk of human uptake. Mean contamination for each scenario was calculated and compared using one-way analysis of variance. P-values of < 0.05 implied significance. RESULTS: Mean cyclophosphamide contamination on trays used to count one, three, and six cyclophosphamide prescriptions was 0.51 +/- 0.10 (p=0.0003), 1.02 +/- 0.10 (p < 0.0001), and 1.82 +/- 0.10 ng/cm2 (p < 0.0001), respectively. Control trays did not show detectable cyclophosphamide contamination. Increasing the number of prescriptions dispensed from 1 to 3, 1 to 6, and 3 to 6 counts increased contamination by 0.51 +/- 0.15 (p = 0.0140), 1.31 + 0.15 (p < 0.0001), and 0.80 +/- 0.15 ng/cm2 (p = 0.0004), respectively. CONCLUSION: Dispensing one or more prescriptions of 40 cyclophosphamide 50 mg tablets contaminates pharmacy counting tools, and an increased number of prescriptions dispensed correlates with increased level of contamination. Counting out three or more prescriptions leads to trays having contamination that surpasses the threshold at which worker exposure may be increased. Pharmacies should consider devoting a separate tray to cyclophosphamide tablets, as cross-contamination could occur with other drugs and the efficacy of decontamination methods is unclear. Employee exposure could be minimized with the use of personal protective equipment, environmental controls, and cleaning trays between uses. Future investigation should assess the extent of drug powder dispersion, the effects of various cleaning methods, and the potential extent of contamination with different oral cytotoxic drugs. PMID- 29592767 TI - Drug shortages in a pediatric stem cell transplantation ward: Challenges and implications. A 5-year bilan. AB - This article describes the implications of shortages of pharmaceutical products used in conditioning and supportive care regimens of pediatric patients undergoing a hematopoietic stem cell transplantation in a tertiary care hospital. Between July 2011 and July 2016, a total of 84 individual shortages, affecting 22 different drugs (79.8% supportive care drugs; 20.2% chemotherapeutics) were detected with a mean duration of 85 days (SD 138) per individual drug shortage. Eighteen shortages were critical and very urgent. Sulfamethoxazol/trimethoprim, piperacillin/tazobactam, ranitidine, benzylpenicillin, ondansetron (supportive care) and methotrexate, melphalan (chemotherapeutics) had the longest supply disruptions. A variety of solutions could be identified including the purchase of a generic alternative (36.9%) for both oral and parenteral treatments (in a ratio 3:2). Urgent import from another (European) country was performed in 14 cases (16.7%). High impact solutions such as cohorting of patients and change of ongoing treatments (2.4%) were used for parenteral treatments only. Pharmaceutical modification was sometimes applied for oral treatments (2.4%). Due to persistent occurrence of these shortages, an efficient pharmacy workflow (electronic follow-up by end of 2016) and a multidisciplinary approach were needed. PMID- 29592768 TI - Effect of deformation history on the stress relaxation behaviour of Colombian Caribbean coastal cheese from goat milk. AB - Textural attributes are a manifestation of the rheological properties and physical structure of foods, cheeses among these. In order to describe these physical properties, the objective of this work was to analyse the effect of deformation history on the stress relaxation behaviour of Colombian Caribbean coastal cheese made from goat milk with 3.75% (F1), 4.00% (F2) and 4.25% (F3) fat content, through prediction made by a four-term Prony series based on Chen's model. For this, stress relaxation data and stress relaxation spectra were analysed. Moreover, textural attributes by texture profile analysis were measured. Physicochemical results were similar to those published by other authors, and all samples meet national and international standards. Results from this work showed that Chen's model could be successfully used to describe the effect of deformation history on the stress relaxation behaviour of Colombian Caribbean coastal cheese made from goat milk. F1 had the highest elastic response, with the most significant residual modules ( P0) and relaxation times (tau1, tau2 and tau3). On the other hand, residual modules and relaxation times (tau1, tau2 and tau3) for cheeses F2 and F3 did not present statistically significant differences (p > 0.05). Besides, by interpretation of the stress relaxation spectra, F1 presented the firmest structure (greatest distribution function and relaxation time) which was characterised by the highest elastic behaviour. Finally, according to texture profile analysis test, F1 had the highest hardness, cohesiveness and chewiness, whereas F2 and F3 did not present statistically significant differences (p > 0.05) between them. PMID- 29592769 TI - All trans retinoic acid modulates TNF-alpha and CYP2E1 pathways and enhances regression of ethanol-induced fibrosis markers in hepatocytes and HSCs in abstaining rodent model. AB - CONTEXT: Our previous studies showed that all trans retinoic acid (ATRA) ameliorates alcohol-induced toxicity. Hence, we evaluated the efficacy of ATRA and abstention in the regression of alcohol-induced hepatotoxicity. MATERIALS AND METHODS: After ethanol administration to rats for 90 days, the regression of alcohol-induced toxicity was studied by supplementing ATRA at a dose of 100 MUg/kg body weight for 30 days. It was also compared with animals in abstention. RESULTS AND DISCUSSION: Ethanol administration enhanced oxidative stress, activated HSCs and increased collagen deposition. All these alterations were reversed to a certain extent by ATRA supplementation. CONCLUSIONS: ATRA had better efficacy than just abstention in reducing ethanol-induced toxicity. The mechanism might be downregulation of CYP2E1, leading to reduced oxidative stress in the hepatocytes and thus impeding NFkappaB activation, cytokine production, activation of HSC and resulting in the reduction of inflammation and remodelling of fibrosis by modulating MMP and TIMP. PMID- 29592770 TI - Using Systems Theory to Examine Patient and Nurse Structures, Processes, and Outcomes in Centralized and Decentralized Units. AB - OBJECTIVES: This study utilizes systems theory to understand how changes to physical design structures impact communication processes and patient and staff design-related outcomes. BACKGROUND: Many scholars and researchers have noted the importance of communication and teamwork for patient care quality. Few studies have examined changes to nursing station design within a systems theory framework. METHOD: This study employed a multimethod, before-and-after, quasi experimental research design. Nurses completed surveys in centralized units and later in decentralized units ( N = 26pre, N = 51post). Patients completed surveys ( N = 62pre) in centralized units and later in decentralized units ( N = 49post). Surveys included quantitative measures and qualitative open-ended responses. RESULTS: Patients preferred the decentralized units because of larger single occupancy rooms, greater privacy/confidentiality, and overall satisfaction with design. Nurses had a more complex response. Nurses approved the patient rooms, unit environment, and noise levels in decentralized units. However, they reported reduced access to support spaces, lower levels of team/mentoring communication, and less satisfaction with design than in centralized units. Qualitative findings supported these results. Nurses were more positive about centralized units and patients were more positive toward decentralized units. CONCLUSION: The results of this study suggest a need to understand how system components operate in concert. A major contribution of this study is the inclusion of patient satisfaction with design, an important yet overlooked fact in patient satisfaction. Healthcare design researchers and practitioners may consider how changing system interdependencies can lead to unexpected changes to communication processes and system outcomes in complex systems. PMID- 29592772 TI - To Grow as a Physician, Try Responding to Suffering. PMID- 29592771 TI - Top Five Physical Design Factors Contributing to Fall Initiation. AB - PURPOSE:: To develop a prioritized list of physical design questions/interventions to reduce patient falls by conducting expanded analysis (Phase II) of data generated from a completed study phase. BACKGROUND:: Patient falls continue to be a critical concern for healthcare providers, patients, and families. While substantial literature exist on intrinsic factors, scientific evidence on the role of the physical environment is scarce. METHOD:: Expanded analysis of data from 180 videos of trials conducted in a physical mock-up of a medical-surgical inpatient room in a previously completed study phase. The odds of subject's exhibited postures (predictors) on fall initiation (outcome) were examined in a series of generalized linear mixed effects models. Physical design elements and attributes associated with postures exhibiting statistical significance were examined. RESULTS:: Turning, pulling, pushing, and bending forward exhibited the highest odds of contributing to fall initiation in the bathroom. Grabbing, pushing, and sitting exhibited the highest odds of contributing to fall initiation around the patient bed. Physical design elements/attributes associated with the above postures are the (1) bathroom door; (2) bathroom spatial configuration-relative locations of door, toilet bowl, and the sink; (3) door, toilet, and sink hardware; (4) space availability/tightness inside the clinician zone; and (5) spatial configuration around patient bed relative locations of bed, patient chair, and overbed table, in relation to bathroom door, and resulting obstructions originating from the configuration. CONCLUSIONS:: Patient falls during unassisted ambulation may be reduced through appropriate examination of these five physical elements/attributes. PMID- 29592773 TI - Effect of changing from preserved prostaglandins to preservative-free tafluprost in patients with glaucoma on tear film thickness. AB - PURPOSE: Long-term glaucoma therapy with preservative-containing eye drops may impact ocular surface health. This study was performed to investigate whether a switch from preserved topical prostaglandin therapy to preservative-free tafluprost therapy improves precorneal tear film thickness in patients with glaucoma or ocular hypertension. METHODS: A total of 30 patients who were under topical preservative-containing prostaglandin monotherapy for at least 6 months were included. Patients were then switched from preserved prostaglandin therapy to unpreserved tafluprost drops once daily. Tear film thickness was measured at baseline and 4 and 12 weeks after therapy change with an ultrahigh-resolution optical coherence tomography system. Furthermore, clinical measures of ocular surface disease were determined and symptoms were assessed using the Dry Eye Related Quality-of-Life Score. RESULTS: After switching to unpreserved tafluprost, tear film thickness significantly increased from 4.7 +/- 0.5 to 5.0 +/- 0.6 um 4 weeks after therapy change and still tended to be increased after 12 weeks (4.8 +/- 0.7 um). Breakup time significantly increased from 5.1 +/- 2.3 to 7.2 +/- 3.4 s and to 10.1 +/- 3.6 s after therapy change. In addition, a significant decrease in corneal staining score from 1.8 +/- 0.7 to 1.4 +/- 0.8 after 4 weeks and to 0.7 +/- 0.7 after 12 weeks treatment was observed. Switching to preservative-free drops reduced Dry Eye-Related Quality-of-Life Score from 11.4 +/- 11.0 to 5.7 +/- 6.4 and to 4.7 +/- 7.5. CONCLUSION: Our data show that switching to preservative-free tafluprost leads to an increase in tear film thickness, breakup time, and an improvement of Dry Eye-Related Quality-of-Life Score. Our results therefore indicate that a switch to unpreserved tafluprost is beneficial for ocular surface health in patients under long-term preserved prostaglandin eye drops. PMID- 29592774 TI - A Validation Study of the Child Pornography Offender Risk Tool (CPORT). AB - The Child Pornography Offender Risk Tool (CPORT) is a seven-item structured tool to assess the likelihood of future sexual offending over a 5-year fixed follow up. The current study examined 5-year fixed follow-up data (15% any new sexual offense, 9% any new child pornography offense) for a validation sample of 80 men convicted of child pornography offense(s). Although statistical power was low, results were comparable with the development sample: The CPORT had slightly lower predictive accuracy for sexual recidivism for the overall group (area under the curve [AUC] = .70 vs. .74), but these values were not significantly different. Combining the development and validation samples, the CPORT predicted any sexual recidivism (AUC = .72) and child pornography recidivism specifically (AUC = .74), with similar accuracies. CPORT was also significantly predictive of these outcomes for the child pornography offenders with no known contact offenses. Strengths and weaknesses of incorporating CPORT into applied risk assessments are discussed. PMID- 29592775 TI - Macrophage Migration Inhibitory Factor Receptor, CD74, is Overexpressed in Human and Baboon ( Papio Anubis) Endometriotic Lesions and Modulates Endometriotic Epithelial Cell Survival and Interleukin 8 Expression. AB - CD74 is the primary receptor for macrophage migration inhibitory factor (MIF). Although expression of MIF has been described in endometriotic lesions, the cellular localization and function of the MIF receptor, CD74, are poorly understood. To further explore the role of CD74 in the pathophysiology of endometriosis, we utilized specimens from women with diagnostically confirmed endometriosis, women with no signs or symptoms of endometriosis (controls), and 8 baboons with experimentally induced endometriosis. Compared to eutopic endometrium from women with endometriosis, CD74 transcript expression was significantly increased in endometriotic lesion tissue. Similarly, cellular expression of CD74 was significantly greater in ectopic lesion tissue compared to paired eutopic endometrium, which both expressed greater CD74 expression compared to eutopic endometrium from control patients. Localization of CD74 was predominant to epithelial cells of ectopic and matched eutopic endometrium and was not influenced by the stage of the menstrual cycle. Eutopic endometrium from control patients did not express detectable levels of CD74 protein by immunohistochemistry. This pattern of expression and CD74 protein localization could be recapitulated in endometriotic lesion tissue from baboons with experimentally induced disease. Transfection of the endometriotic epithelial cell lines, 12Z with CD74 short hairpin RNA (shRNA), resulted in a significant decrease in CD74 protein expression, which was associated with a significant reduction in cellular proliferation as well as the expression of the prosurvival cytokine interleukin 8. Together, these data support the hypothesis that CD74 is elevated in endometriotic lesion tissue and may contribute to the pathogenesis of endometriosis by promoting cell survival. PMID- 29592776 TI - Epigenetic Dynamics of HOXA10 Gene in Infertile Women With Endometriosis. AB - Endometriosis, which has been considered an epigenetic disease, is a prevalent gynecological disorder worldwide. With an emphasis on changes in the HOXA10 gene expression of the endometrium of women with endometriosis, the aim of this study was to investigate HOXA10 gene expression and its correlation with the epigenetic characteristics of the specific promoter region of the gene in the eutopic and ectopic endometrium of women with endometriosis. Thirty-six patients and 21 healthy fertile women were recruited as participants of this study. In this study group, chromatin immunoprecipitation and real-time polymerase chain reaction technique were performed to quantify the epigenetic profile of HOXA10, parallel to its expression. During the secretory phase in eutopic tissues, reduction in HOXA10 gene expression was identified along with lower acetylation and higher methylation of H3K9 as well as higher incorporation of MeCP2 on the HOXA10 gene promoter. In contrast with control group, studies of ectopic endometriotic lesions in the secretory phase demonstrate a correlation between induction of HOXA10 gene and higher levels of H3K9ac, H3K27me3, and H3K4me3 in the promoter region of the HOXA10 gene. Further distinctions from the control group were revealed in the proliferative phase of the ectopic endometrium, where upregulation of HOXA10 coincided with lower incorporation of MeCP2 and higher levels of H3K4me3 in the promoter region. Since it is well known that aberrant expression of HOXA10 is involved in pathogenesis of the endometrium, our data emphasized the epigenetic role of this gene aberration related to clinical pathophysiology of endometriosis. PMID- 29592777 TI - An intraocular micro light-emitting diode device for endo-illumination during pars plana vitrectomy. AB - PURPOSE: Development of a new, fiber-free, single-use endo-illuminator for pars plana vitrectomy as a replacement for fiber-based systems with external light sources. The hand-guided intraocularly placed white micro light-emitting diode is evaluated for its illumination properties and potential photochemical and thermal hazards. METHODS: A micro light-emitting diode was used to develop a single-use intraocular illumination system. The light-source-on-tip device was implemented in a prototype with 23G trocar compatible outer diameter of 0.6 mm. The experimental testing was performed on porcine eyes. All calculations of possible photochemical and thermal hazards during the application of the intraocular micro light-emitting diode were calculated according to DIN EN ISO 15007-2: 2014. RESULTS: The endo-illuminator generated a homogeneous and bright illumination of the intraocular space. The color impression was physiologic and natural. Contrary to initial apprehension, the possible risk caused by inserting a light-emitting diode into the intraocular vitreous was much smaller when compared to conventional fiber-based illumination systems. The photochemical and thermal hazards allowed a continuous exposure time to the retina of at least 4.7 h. CONCLUSION: This first intraocular light source showed that a light-emitting diode can be introduced into the eye. The system can be built as single-use illumination system. This light-source-on-tip light-emitting diode-endo illumination combines a chandelier wide-angle illumination with an adjustable endo-illuminator. PMID- 29592778 TI - Posterior reversible encephalopathy syndrome in HIV-positive patients: a case report and literature review. AB - We are reporting the case of a woman who was admitted acutely to our intensive care unit without any collateral history. She was diagnosed with posterior reversible encephalopathy syndrome (PRES) as a consequence of poor adherence to anti-hypertensive, anti-diabetic and anti-retroviral medications. PRES is a rare condition, which may cause cortical blindness; contrary to its name it is not always reversible. Rapid diagnosis and aggressive management of underlying causes facilitate reversibility of PRES. We also summarise the literature on patients with HIV and PRES. PMID- 29592779 TI - Associations of Urinary Cotinine-Verified Active and Passive Smoking with Thyroid Function: Analysis of Population-Based Nationally Representative Data. AB - BACKGROUND: The effects of active and passive smoking on thyroid function in the Korean population have not been determined. Furthermore, related research is based on self-reported smoking status, which may be inaccurate, especially among women. The present study aimed at evaluating the association between biochemically verified smoking status and thyroid function in a nationally representative Korean population. METHODS: This population-based cross-sectional study included 3404 subjects without thyroid disease who were not taking thyroid medication. Smoking status was identified using self-reported data and urinary cotinine levels. Kruskal-Wallis and Jonckheere-Terpstra trend tests were performed to evaluate the association between smoking exposure and thyroid function. Multivariate logistic regression analysis was used to estimate the effect of smoking on subclinical hypothyroidism (SCH). RESULTS: Biochemically verified active and passive smoking rates were 43.4% and 23.3% among men and 10.0% and 22.9% among women, respectively. Active smokers had significantly lower iodine levels than passive smokers and nonsmokers. Active smoking was associated with decreased serum thyrotropin (TSH) levels among both sexes, although only men exhibited a dose-response relationship between increasing smoking exposure and decreasing TSH levels. Passive smoking slightly decreased TSH levels, but the decrease was not statistically significant. The risk of SCH decreased with increasing smoking exposure in the multivariate-adjusted analysis (p for trend = 0.027 among men and 0.042 among women). CONCLUSIONS: Active and passive smoking were associated with decreasing serum TSH levels and a lower risk of SCH in a Korean population. These associations might be related to lower urinary iodine levels in active smokers. PMID- 29592780 TI - Downregulation of neuroligin1 ameliorates postoperative pain through inhibiting neuroligin1/postsynaptic density 95-mediated synaptic targeting of alpha-amino-3 hydroxy-5-methyl-4-isoxazole propionate receptor GluA1 subunits in rat dorsal horns. AB - Neuroligin1 is an important synaptic cell adhesion molecule that modulates the function of synapses through protein-protein interactions. Yet, it remains unclear whether the regulation of synaptic transmission in the spinal cord by neruoligin1 contributes to the development of postoperative pain. In a rat model of postoperative pain induced by plantar incision, we conducted Western blot study to examine changes in the expression of postsynaptic membrane of neuroligin1, postsynaptic density 95 (PSD-95), and alpha-amino-3-hydroxy-5-methyl 4-isoxazole propionate (AMPA) receptor GluA1 and GluA2 subunits in the spinal cord dorsal horn after injury. The interaction between neuroligin1 and PSD-95 was further determined by using coimmunoprecipitation. Protein levels of neuroligin1 and GluA1, but not GluA2 and PSD-95, were significantly increased in the postsynaptic membrane of the ipsilateral dorsal horn at 3 h and 1 day after incision, as compared to that in control group (naive). A greater amount of PSD 95 was coimmunoprecipitated with neuroligin1 at 3 h after incision than that in the control group. Intrathecal administration of small interfering RNAs (siRNAs) targeting neuroligin1 suppressed the expression of neuroligin1 in the spinal cord. Importantly, pretreatment with intrathecal neuroligin1 siRNA2497, but not scrambled siRNA or vehicle, prevented the upregulation of GluA1 expression at 3 h after incision, inhibited the enhanced neuroligin1/PSD-95 interaction, and attenuated postoperative pain. Together, current findings suggest that downregulation of spinal neuroligin1 expression may ameliorate postoperative pain through inhibiting neuroligin1/PSD-95 interaction and synaptic targeting of GluA1 subunit. Accordingly, spinal neuroligin1 may be a potential new target for postoperative pain treatment. PMID- 29592781 TI - No requirement of interlukine-1 for long-term potentiation in the anterior cingulate cortex of adult mice. AB - : Background The enhanced expression of cytokines in the pathological states suggests that they have important roles in the initiation or maintenance of disease states. FINDINGS: To determine the involvement of cytokines in chronic neuropathic pain, the expression of cytokines in the anterior cingulate cortex neurons in the ligation of the common peroneal nerve mice was investigated. We utilized a cytokine enzyme-linked immunosorbent assay plate array to detect 23 cytokines in total eight mice including a female, and no significant differences were found in those cytokines between the common peroneal nerve model and sham surgery mice. Quantification of TNF-alpha at protein level revealed the unvaried expression in the anterior cingulate cortex in both neuropathic pain and visceral pain, but enhanced expression in the insular cortex in the visceral pain. Furthermore, we found that the IL-Ira, a kind of IL-1 receptor antagonist, had no effect on the theta burst stimulation-induced long-term potentiation in the anterior cingulate cortex. Conclusions Cytokines are not involved in chronic neuropathic pain induced by nerve injury in the anterior cingulate cortex. Our findings suggested that cytokines may not be a viable drug target to treat chronic neuropathic pain in the anterior cingulate cortex. PMID- 29592782 TI - Resveratrol enhances IL-4 receptor-mediated anti-inflammatory effects in spinal cord and attenuates neuropathic pain following sciatic nerve injury. AB - Resveratrol has been showed to relieve neuropathic pain through its anti inflammatory effects on the peripheral nerve system. However, it is not clear whether resveratrol, especially when administered systemically, is effective in alleviating the peripheral neuropathy-induced imbalance between pro- and anti inflammatory responses in the central nervous system. To test this, we used a rat neuropathic pain model resulting from chronic constriction injury of the sciatic nerve. Resveratrol (200 mg/kg) or vehicle (dimethylsulfoxide) were administered intraperitoneally once daily for 14 consecutive days after chronic constriction injury. We found that resveratrol attenuated mechanical allodynia and thermal hyperalgesia in rats with chronic constriction injury. After 14 days of resveratrol treatment, expression of several anti-inflammatory cytokine receptors, including IL-1RA and IL-1R2, was increased in the dorsal spinal cord of rats with chronic constriction injury, and IL-4Ralpha was increased in dorsal spinal cord neurons. Knockdown of IL-4Ralpha in a neuronal cell line reversed the resveratrol-induced upregulation of IL-1RA and IL-1R2. These results indicate that resveratrol enhances IL-4 receptor-mediated anti-inflammatory responses in the spinal cord and thus might contribute to the alleviation of central sensitization following peripheral nerve injury. PMID- 29592783 TI - Synergistic activation of ERK1/2 between A-fiber neurons and glial cells in the DRG contributes to pain hypersensitivity after tissue injury. AB - Background Intense nociceptive signaling arising from ongoing injury activates primary afferent nociceptive systems to generate peripheral sensitization. ERK1/2 phosphorylation in dorsal root ganglion can be used to visualize intracellular signal activity immediately after noxious stimulation. The aim of this study was to investigate spatiotemporal characteristics of ERK1/2 phosphorylation against tissue injury in the primary afferent neurons. Methods Plantar incisions were made in the hind paws of Sprague-Dawley rats (n =150). Levobupivacaine was injected into the plantar aspect of the paws and ankles, Mitogen-activated protein kinase kinase (MEK) inhibitor was injected into the paw, and carbenoxolone, dual inhibitor of the gap junction and pannexin channel, was intraperitoneally injected. Pain hypersensitivity was investigated by a behavioral study, while phosphorylated ERK1/2 was detected in dorsal root ganglion and hind paw using immunohistochemistry and Western blot. Results Phosphorylated ERK1/2 was induced in dorsal root ganglion (26.8 +/- 2.9% at baseline, 65.6 +/- 3.6% at 2 min, and 26.3 +/- 3.4% at 2 h) after the incision. NF-200 positive A-fiber neurons and satellite glial cells were positive for phosphorylated ERK1/2. Injury-induced pain hypersensitivity was abolished by MEK inhibitor. Levobupivacaine treatment inhibited phosphorylated ERK1/2 induction, carbenoxolone treatment inhibited glial phosphorylated ERK1/2 at 2 min after the injury, and carbenoxolone inhibited pain hypersensitivity and neuronal phosphorylated ERK1/2 at 1 h after the injury. Conclusion ERK1/2 phosphorylation in A-fiber neurons and satellite glial cells immediately after injury contributes to the generation of pain hypersensitivity. Signal communication between neurons and satellite glial cells expands the duration of neuronal ERK1/2 phosphorylation and pain hypersensitivity at 1 h after tissue injury. PMID- 29592784 TI - The analgesic effect of early hyperbaric oxygen treatment in chronic constriction injury rats and its influence on nNOS and iNOS expression and inflammatory factor production. AB - Objective To observe the analgesic effect of early hyperbaric oxygen (HBO) treatment in chronic constriction injury (CCI) rats, and to analyze the influence of HBO on the expression of neuronal nitric oxide synthase and inducible nitric oxide synthase and on the levels of inflammatory factors. Methods Rats were assigned into three groups randomly: sham, CCI, and HBO groups. The CCI rat model was established, and HBO treatment at 2.5 ATA (60 min) was given one day after surgery, lasting for five consecutive days. The pain behaviors of the rats were observed at predetermined time points, and the activation of astrocytes at dorsal horns as well as the changes of the synaptic ultrastructures were observed. The expressions of inducible nitric oxide synthase and neuronal nitric oxide synthase were detected by Western blot, and the levels of tumor necrosis factor-alpha (TNF alpha) and interleukin-1 beta (IL-1beta) were detected by quantitative real-time PCR. Results Rats in the CCI group developed hyperalgesia when compared with the sham group. Mechanical withdrawal threshold decreased and thermal withdrawal latency shortened in CCI group. Also, astrocytes at the dorsal horn were activated, the synaptic structure was disordered, the expressions of inducible nitric oxide synthase and neuronal nitric oxide synthase were increased significantly, and the release of inflammatory factor (TNF-alpha and IL-1beta) was up-regulated. However, with early initiation of HBO treatment, rats in the HBO group showed significantly alleviated hyperalgesia, increased mechanical withdrawal threshold, and prolonged thermal withdrawal latency. HBO treatment inhibited astrocyte expression and maintained normal synaptic structure. The expressions of inducible nitric oxide synthase and neuronal nitric oxide synthase were decreased in the dorsal horn, and the release of inflammatory factor (TNF alpha and IL-1beta) was reduced. Conclusions Early HBO treatment significantly improves hyperalgesia in rats with neuropathic pain. The decreased expressions of inducible nitric oxide synthase and neuronal nitric oxide synthase and reduced levels of inflammatory factors are important mechanisms by which early HBO helps to alleviate neuropathic pain.

AB - Community participation as a strategy in health aims to increase the role of citizens in health decision-making which are contextualised within the institutions of democracy. Electoral representation as the dominant model of democracy globally is based on the elite theory of democracy that sees political decision-making a prerogative of political elites. Such political elitism is counter to the idea of democratic participation. Neoliberalism together with elitism in political sphere have worsened social inequities by undermining working class interests. Latin America has seen adverse consequences of these social inequities. In response, social movements representing collective struggles of organised citizens arose in the region. This paper explores the theoretical underpinnings of democratic participation in contemporary Latin American context at the nexus of emerging social movement activism and policy responses. The paper will use empirical examples to highlight how such democratic practices at the societal level evolved while demanding political inclusion. These societal democratic practices in Latin America are redefining democracy, which continues to be seen in the political sphere only. Health reforms promoting participatory democracy in several Latin American countries have demonstrated that establishing institutions and mechanisms of democratic participation facilitate collective participation by the organised citizenry in state affairs. PMID- 29592785 TI - Increased expression of CaV3.2 T-type calcium channels in damaged DRG neurons contributes to neuropathic pain in rats with spared nerve injury. AB - Ion channels are very important in the peripheral sensitization in neuropathic pain. Our present study aims to investigate the possible contribution of CaV3.2 T type calcium channels in damaged dorsal root ganglion neurons in neuropathic pain. We established a neuropathic pain model of rats with spared nerve injury. In these model rats, it was easy to distinguish damaged dorsal root ganglion neurons (of tibial nerve and common peroneal nerve) from intact dorsal root ganglion neurons (of sural nerves). Our results showed that CaV3.2 protein expression increased in medium-sized neurons from the damaged dorsal root ganglions but not in the intact ones. With whole cell patch clamp recording technique, it was found that after-depolarizing amplitudes of the damaged medium sized dorsal root ganglion neurons increased significantly at membrane potentials of -85 mV and -95 mV. These results indicate a functional up-regulation of CaV3.2 T-type calcium channels in the damaged medium-sized neurons after spared nerve injury. Behaviorally, blockade of CaV3.2 with antisense oligodeoxynucleotides could significantly reverse mechanical allodynia. These results suggest that CaV3.2 T-type calcium channels in damaged medium-sized dorsal root ganglion neurons might contribute to neuropathic pain after peripheral nerve injury.

PMID- 29592786 TI - Attenuation of offset analgesia is associated with suppression of descending pain modulatory and reward systems in patients with chronic pain. AB - Background Offset analgesia is a disproportionate decrease of pain perception following a slight decrease of noxious thermal stimulus and attenuated in patients with neuropathic pain. We examined offset analgesia in patients with heterogeneous chronic pain disorders and used functional magnetic resonance imaging to explore modification of cerebral analgesic responses in comparison with healthy controls. Results We recruited seventeen patients with chronic pain and seventeen age-, sex-matched healthy controls. We gave a noxious thermal stimulation paradigm including offset analgesia and control stimuli on the left volar forearm, while we obtained a real-time continuous pain rating and a whole brain functional magnetic resonance imaging. Baseline, first plateau (5 s), increment (5 s), and second plateau (20 s) temperatures of offset analgesia stimulus were set at 32 degrees C, 46 degrees C, 47 degrees C, and 46 degrees C, respectively. Control stimulus included 30-s 46 degrees C stimulus or only the first 10 s of offset analgesia stimulus. We evaluated magnitude of offset analgesia, analyzed cerebral activation by thermal stimulation, and further compared offset analgesia-related activation between the groups. Magnitude of offset analgesia was larger in controls than in patients (median: 28.9% (interquartile range: 11.0-56.0%) vs. 19.0% (4.2-48.7%), p = 0.047). During the second plateau, controls showed a larger blood oxygenation level-dependent activation than patients at the putamen, anterior cingulate, dorsolateral prefrontal cortices, nucleus accumbens, brainstem, and medial prefrontal cortex ( p < 0.05), which are known to mediate either of descending pain modulation or reward responses. Offset analgesia-related activity at the anterior cingulate cortex was negatively correlated with neuropathic component of pain in patients with chronic pain ( p = 0.004). Conclusions Attenuation of offset analgesia was associated with suppressed activation of the descending pain modulatory and reward systems in patients with chronic pain, at least in the studied cohort. The present findings might implicate both behavioral and cerebral plastic alterations contributing to chronification of pain.

AB - A new mortality model based on a mixture distribution function is proposed. We mix a half-normal distribution with a generalization of the skew-normal distribution. As a result, we get a six-parameter distribution function that has a good fit with a wide variety of mortality patterns. This mixture model is fitted to several mortality data schedules and compared with the Siler (five parameter) and Heligman-Pollard (eight-parameter) models. Our proposal serves as a convenient compromise between the Heligman-Pollard model (which ensures a good fit with data but is often overparameterized) and the Siler model (which is more compact but fails to capture 'accident humps'). PMID- 29592795 TI - Phylogenomics of palearctic Formica species suggests a single origin of temporary parasitism and gives insights to the evolutionary pathway toward slave-making behaviour. AB - BACKGROUND: The ants of the Formica genus are classical model species in evolutionary biology. In particular, Darwin used Formica as model species to better understand the evolution of slave-making, a parasitic behaviour where workers of another species are stolen to exploit their workforce. In his book "On the Origin of Species" (1859), Darwin first hypothesized that slave-making behaviour in Formica evolved in incremental steps from a free-living ancestor. METHODS: The absence of a well-resolved phylogenetic tree of the genus prevent an assessment of whether relationships among Formica subgenera are compatible with this scenario. In this study, we resolve the relationships among the 4 palearctic Formica subgenera (Formica str. s., Coptoformica, Raptiformica and Serviformica) using a phylogenomic dataset of 945 genes for 16 species. RESULTS: We provide a reference tree resolving the relationships among the main Formica subgenera with high bootstrap supports. DISCUSSION: The branching order of our tree suggests that the free-living lifestyle is ancestral in the Formica genus and that parasitic colony founding could have evolved a single time, probably acting as a pre-adaptation to slave-making behaviour. CONCLUSION: This phylogenetic tree provides a solid backbone for future evolutionary studies in the Formica genus and slave-making behaviour. PMID- 29592796 TI - C3 glomerulopathy in cystic fibrosis: a case report. AB - BACKGROUND: C3 glomerulonephritis is a rare glomerulopathy characterized at renal biopsy by C3 deposition, alone or with scanty immunoglobulins, as well as by an electron-dense material in mesangium, subendothelial and subepithelial space. An abnormal systemic activation of the alternative pathway of the complement cascade is responsible for the development of the disease if triggered by several possible environmental conditions. We report the first case in literature of a patient affected by cystic fibrosis and C3GN. CASE PRESENTATION: Our case involves a young woman with cystic fibrosis, who had persistent microscopic hematuria, proteinuria and hypocomplementemia C3 for over three months. Renal biopsy confirmed the diagnosis of C3 glomerulopathy. Complement system dysregulation was tested and resulted in a strong terminal pathway activation proved by high levels of sC5b-9 complex, amounting to 1588 ng/ml (normal value < 400 ng/ml). Next generation sequencing (NGS) showed polymorphism in CFH (p.V62I in SCR1) and THBD (p.A473V), already known as pathogenic for C3GN, as well as a mutation in C3 (p.R102G) associated only with age-related macular degeneration (AMD) so far. Treatment was based on ACE inhibitors and kidney function is currently stable (GFR 50 ml/min, serum creatinine 1.7). CONCLUSIONS: The co existence of C3 glomerulopathy in a patient with CF, which is characterized by chronic infection/inflammation, makes this case an interesting model of chronic altered systemic activation of the alternative pathway of the complement cascade. PMID- 29592797 TI - Prevalence of and risk factors for tuberculosis among healthcare workers in Chinese tuberculosis facilities. AB - BACKGROUND: China is one of 22 countries with a high tuberculosis (TB) burden in the world. Healthcare workers (HCWs) have a high risk of contracting Mycobacterium tuberculosis infection due to insufficient infection control practices. We conducted a cross-sectional study to explore the prevalence of TB and its associated risk factors among HCWs in Chinese TB facilities. METHODS: Two hundred and forty-one TB facilities employing a total of 9663 HCWs were selected from 12 provinces in China to represent healthcare settings at the provincial, prefectural, and county levels. Structured questionnaires were used to collect information on TB infection control practices and HCWs in those facilities. Data was double entered into EpiData 3.1; TB prevalence and associated risk factors were analyzed using SPSS 21.0 with bivariate and multivariate regression models. RESULTS: The results showed that 71 HCWs had been diagnosed with TB, accounting for a prevalence of 760/100 000. The multivariate analysis showed that associated risk factors included belonging to the age group of 51 years and above (aOR: 6.17, 95% CI: 1.35-28.28), being a nurse (aOR = 3.09, 95% CI: 1.15-8.32), implementation of 0-9 items of management measures (aOR = 2.57, 95% CI: 1.37 4.80), and implementation of 0-1 items of ventilation measures (aOR = 2.42, 95% CI: 1.31-4.47). CONCLUSION: This was the first national large sampling survey on TB prevalence among HCWs in China. It was found that the implementation of TB infection control practices in some facilities was poor. The TB prevalence in HCWs was higher than that in the general population. Therefore, TB infection control practices in Chinese medical facilities should be strengthened. PMID- 29592798 TI - Comparative investigation on the sizes and scavenger receptor binding of human native and modified lipoprotein particles with atomic force microscopy. AB - BACKGROUND: The size and receptor-binding abilities of plasma lipoproteins are closely related with their structure/functions. Presently, the sizes of native lipoproteins have been measured by various methods including atomic force microscopy (AFM) whereas the sizes of modified lipoproteins are poorly determined and the receptor-binding ability of lipoproteins is less detected and compared at the nanoscale. METHODS: Here, AFM was utilized to detect/compare the size and scavenger receptor-binding properties of three native human lipoproteins including high-density lipoprotein, low-density lipoprotein (LDL), and very low density lipoprotein, and two modified human lipoproteins including oxidized and acetylated LDL, as well as bovine serum albumin and their antibodies as negative and positive controls, respectively. RESULTS: AFM detected that the sizes of these lipoproteins are close to the commonly known values and the previously reported AFM-detected sizes and that native and modified LDL have different height/size. AFM also revealed that the CD36-binding abilities of the five lipoproteins are different from one another and from their SR-B1-binding abilities and that the anti-CD36/SR-B1 antibodies as positive controls have strong CD36/SR-B1-binding abilities. CONCLUSIONS: The data provide important information on lipoproteins for better understanding their structures/functions. Moreover, the data certify that besides size measurement AFM also can visualize receptor-lipoprotein binding at the nanoscale, as well as antigen-antibody (scavenger receptors and their antibodies) binding. PMID- 29592799 TI - Between-population differences in the genetic and maternal components of body mass in roe deer. AB - BACKGROUND: Understanding the genetic and environmental mechanisms governing variation in morphology or phenology in wild populations is currently an important challenge. While there is a general consensus that selection is stronger under stressful conditions, it remains unclear whether the evolutionary potential of traits should increase or decrease with increasingly stressful conditions. Here, we investigate how contrasting environmental conditions during growth may affect the maternal and genetic components of body mass in roe deer, the most abundant and widespread wild ungulate in Western Europe. Body mass is a key life history trait that strongly influences both survival and reproductive performance in large herbivores. We used pedigrees and animal models to determine the variance components of juvenile and adult winter body mass in two populations experiencing contrasting early-life conditions. RESULTS: Our analyses showed that roe deer at Chize, where habitat was poor and unpredictable, exhibited very low genetic variance in juvenile body mass. Instead, variance in mass was mainly driven by among-cohort differences in early-life conditions and maternal environment. In contrast, roe deer at Bogesund, where resource availability during the critical period of fawn rearing was higher, displayed a substantial level of genetic variance in body mass. We discuss the potential role of past demography and viability selection on fawn body mass on the erosion of genetic variance in the poor habitat. CONCLUSIONS: Our study highlights the importance of accounting for both spatial (i.e. between-population variation) and temporal (i.e. cohort variation) heterogeneity in environmental conditions, especially in early life, to understand the potential for adaptive responses of wild populations to selection. PMID- 29592800 TI - Evaluation of the effect of methamphetamine on traumatic injury complications and outcomes. AB - BACKGROUND: This study investigates the impact of methamphetamine use on trauma patient outcomes. METHODS: This retrospective study analyzed patients between 18 and 55 years old presenting to a single trauma center in San Bernardino County, CA who sustained traumatic injury during the 10-year study period (January 1st, 2005 to December 31st, 2015). Routine serum ethanol levels and urine drug screens (UDS) were completed on all trauma patients. Exclusion criteria included patients with an elevated serum ethanol level (> 0 mg/dL). Those who screened positive on UDS for only methamphetamine and negative for cocaine and cannabis (MA(+)) were compared to those with a triple negative UDS for methamphetamine, cocaine, and cannabis (MA(-)). The primary outcome studied was the impact of a methamphetamine positive drug screen on hospital mortality. Secondary outcomes included length of stay (LOS), heart rate, systolic and diastolic blood pressure (SBP and DBP, respectively), and total amount of blood products utilized during hospitalization. To analyze the effect of methamphetamine, age, gender, injury severity score, and mechanism of injury (blunt vs. penetrating) were matched between MA(-) and MA(+) through a propensity matching algorithm. RESULTS: After exclusion, 2538 patients were included in the final analysis; 449 were patients in the MA(+) group and 2089 patients in the MA(-) group. A selection of 449 MA(-) patients were matched with the MA(+) group based on age, gender, injury severity score, and mechanism of injury. This led to a final sample size of 898 patients with 449 patients in each group. No statistically significant change was observed in hospital mortality. Notably, a methamphetamine positive drug screen was associated with a longer LOS (median of 4 vs. 3 days in MA(+) and MA(-), respectively, p < 0.0001), an increased heart rate at the scene (103 vs. 94 bpm for MA(+) and MA(-), respectively, p = 0.0016), and an increased heart rate upon arrival to the trauma center (100 vs. 94 bpm for MA(+) and MA(-), respectively, p < 0.0001). Moreover, the MA(+) group had decreased SBP at the scene compared to the MA(-) group (127 vs. 132 bpm for MA(+) and MA(-), respectively, p = 0.0149), but SBP was no longer statistically different when patients arrived at the trauma center (p = 0.3823). There was no significant difference in DBP or in blood products used. CONCLUSION: Methamphetamine positive drug screens in trauma patients were not associated with an increase in hospital mortality; however, a methamphetamine positive drug screen was associated with a longer LOS and an increased heart rate. PMID- 29592801 TI - Standardised alcohol screening in primary health care services targeting Aboriginal and Torres Strait Islander peoples in Australia. AB - INTRODUCTION AND AIMS: Aboriginal and Torres Strait Islander Community Controlled Health Services (ACCHSs) around Australia have been asked to standardise screening for unhealthy drinking. Accordingly, screening with the 3-item AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) tool has become a national key performance indicator. Here we provide an overview of suitability of AUDIT-C and other brief alcohol screening tools for use in ACCHSs. METHODS: All peer-reviewed literature providing original data on validity, acceptability or feasibility of alcohol screening tools among Indigenous Australians was reviewed. Narrative synthesis was used to identify themes and integrate results. RESULTS: Three screening tools-full AUDIT, AUDIT-3 (third question of AUDIT) and CAGE (Cut down, Annoyed, Guilty and Eye-opener) have been validated against other consumption measures, and found to correspond well. Short forms of AUDIT have also been found to compare well with full AUDIT, and were preferred by primary care staff. Help was often required with converting consumption into standard drinks. Researchers commented that AUDIT and its short forms prompted reflection on drinking. Another tool, the Indigenous Risk Impact Screen (IRIS), jointly screens for alcohol, drug and mental health risk, but is relatively long (13 items). IRIS has been validated against dependence scales. AUDIT, IRIS and CAGE have a greater focus on dependence than on hazardous or harmful consumption. DISCUSSION AND CONCLUSIONS: Detection of unhealthy drinking before harms occur is a goal of screening, so AUDIT-C offers advantages over tools like IRIS or CAGE which focus on dependence. AUDIT-C's brevity suits integration with general health screening. Further research is needed on facilitating implementation of systematic alcohol screening into Indigenous primary healthcare. PMID- 29592802 TI - Physiotherapists' views of implementing a stratified treatment approach for patients with low back pain in Germany: a qualitative study. AB - BACKGROUND: The STarT-Back-Approach (STarT: Subgroups for Targeted Treatment) was developed in the UK and has demonstrated clinical and cost effectiveness. Based on the results of a brief questionnaire, patients with low back pain are stratified into three treatment groups. Since the organisation of physiotherapy differs between Germany and the UK, the aim of this study is to explore German physiotherapists' views and perceptions about implementing the STarT-Back Approach. METHODS: Three two-hour think-tank workshops with physiotherapists were conducted. Focus groups, using a semi-structured interview guideline, followed a presentation of the STarT-Back-Approach, with discussions audio recorded, transcribed and qualitatively analysed using content analysis. RESULTS: Nineteen physiotherapists participated (15 female, mean age 41.2 (SD 8.6) years). Three main themes emerged, each with multiple subthemes: 1) the intervention (15 subthemes), 2) the healthcare context (26 subthemes) and 3) individual characteristics (8 subthemes). Therapists' perceptions of the extent to which the STarT-Back intervention would require changes to their normal clinical practice varied considerably. They felt that within their current healthcare context, there were significant financial disincentives that would discourage German physiotherapists from providing the STarT-Back treatment pathways, such as the early discharge of low-risk patients with supported self-management materials. They also discussed the need for appropriate standardised graduate and post graduate skills training for German physiotherapists to treat high-risk patients with a combined physical and psychological approach (e.g., communication skills). CONCLUSIONS: Whilst many German physiotherapists are positive about the STarT Back-Approach, there are a number of substantial barriers to implementing the matched treatment pathways in Germany. These include financial disincentives within the healthcare system to early discharge of low-risk patients. Therapists also highlighted the need for solutions in respect of scalable physiotherapy training to gain skills in combined physical and psychological approaches. PMID- 29592803 TI - Development an effective system to expression recombinant protein in E. coli via comparison and optimization of signal peptides: Expression of Pseudomonas fluorescens BJ-10 thermostable lipase as case study. AB - BACKGROUND: Thermostable lipases from microbial sources have been substantially overexpressed in E. coli, however, these enzymes are often produced with low level enzymatic activity and mainly in the form of inclusion bodies. Several studies have reported that the secretory production of recombinant proteins fused their N-terminus to a signal peptide has been employed to resolve the problem. In general, the feasibility of this approach largely depends on the secretory pathway of signal peptide and the type of target protein to be secreted. This study was performed to compare and optimize signal peptides for efficient secretion of thermostable lipase lipBJ10 from Pseudomonas fluorescens BJ-10. Meanwhile, a comparative study between this method and cytoplasmic secretion was implemented in secreting soluble and active lipases. RESULTS: Fusion expression using six signal peptides, i.e., PelB and five native E. coli signal peptides, as fusion partners produced more soluble and functional recombinant lipBJ10 than non fusion expression. Recombinant lipBJ10, fused to these six diverse signal peptides, was secreted into the periplasm in E. coli. The total lipase activity in all cases of fusion expression was higher than those in non-fusion expression. The relative activity peaked when lipBJ10 was fused to DsbA, yielding a value 73.3 times greater than that of the non-fusion protein. When DsbA was used as the fusion partner, the highest activity (265.41 U/ml) was achieved with the least formation of inclusion bodies; the other four E. coli signal peptides, to some extent, led to low activity and insoluble inclusion bodies. Therefore, DsbA is the optimal signal peptide partner to fuse with lipBJ10 to efficiently produce soluble and functional protein. CONCLUSION: We found that fusing to these signal peptides, especially that of DsbA, can significantly decrease the formation of inclusion bodies and enhance the function and solubility of lipBJ10 compared to non-fusion lipBJ10. Our results reported here can provide a reference for the high-level expression of other lipases with respect to a possible industrial application. PMID- 29592804 TI - Metabolic engineering of a xylose pathway for biotechnological production of glycolate in Escherichia coli. AB - BACKGROUND: Glycolate is a valuable chemical with extensive applications in many different fields. The traditional methods to synthesize glycolate are quite expensive and toxic. So, the biotechnological production of glycolate from sustainable feedstocks is of interest for its potential economic and environmental advantages. D-Xylose is the second most abundant sugar in nature and accounts for 18-30% of sugar in lignocellulose. New routes for the conversion of xylose to glycolate were explored. RESULTS: Overexpression of aceA and ghrA and deletion of aceB in Escherichia coli were examined for glycolate production from xylose, but the conversion was initially ineffective. Then, a new route for glycolate production was established in E. coli by introducing NAD+-dependent xylose dehydrogenase (xdh) and xylonolactonase (xylC) from Caulobacter crescentus. The constructed engineered strain Q2562 produced 28.82 +/- 0.56 g/L glycolate from xylose with 0.60 +/- 0.01 g/L/h productivity and 0.38 +/- 0.07 g/g xylose yield. However, 27.18 +/- 2.13 g/L acetate was accumulated after fermentation. Deletions of iclR and ackA were used to overcome the acetate excretion. An ackA knockout resulted in about 66% decrease in acetate formation. The final engineered strain Q2742 produced 43.60 +/- 1.22 g/L glycolate, with 0.91 +/- 0.02 g/L/h productivity and 0.46 +/- 0.03 g/g xylose yield. CONCLUSIONS: A new route for glycolate production from xylose was established, and an engineered strain Q2742 was constructed from this new explored pathway. The engineering strain showed the highest reported productivity of glycolate to date. This research opened up a new prospect for bio-refinery of xylose and an alternative choice for industrial production of glycolate. PMID- 29592805 TI - Liver toxicity associated with tuberculosis chemotherapy in the REMoxTB study. AB - BACKGROUND: Drug-induced liver injury (DILI) is a common complication of tuberculosis treatment. We utilised data from the REMoxTB clinical trial to describe the incidence of predisposing factors and the natural history in patients with liver enzyme levels elevated in response to tuberculosis treatment. METHODS: Patients received either standard tuberculosis treatment (2EHRZ/4HR), or a 4-month regimen in which moxifloxacin replaced either ethambutol (isoniazid arm, 2MHRZ/2MHR) or isoniazid (ethambutol arm, 2EMRZ/2MR). Hepatic enzymes were measured at 0, 2, 4, 8, 12 and 17 weeks and as clinically indicated during reported adverse events. Patients included were those receiving at least one dose of drug and with two or more hepatic enzyme measurements. RESULTS: A total of 1928 patients were included (639 2EHRZ/4HR, 654 2MHRZ/2MHR and 635 2EMRZ/2MR). DILI was defined as peak alanine aminotransferase (ALT) >= 5 times the upper limit of normal (5 * ULN) or ALT >= 3 * ULN with total bilirubin > 2 * ULN. DILI was identified in 58 of the 1928 (3.0%) patients at a median time of 28 days (interquartile range IQR 14-56). Of 639 (6.4%) patients taking standard tuberculosis therapy, 41 experienced clinically significant enzyme elevations (peak ALT >= 3 * ULN). On standard therapy, 21.1% of patients aged >55 years developed a peak ALT/aspartate aminotransferase (AST) >= 3 * ULN (p = 0.01) and 15% of HIV-positive patients experienced a peak ALT/AST >= 3 * ULN compared to 9% of HIV-negative patients (p = 0.160). The median peak ALT/AST was higher in isoniazid-containing regimens vs no-isoniazid regimens (p < 0.05), and lower in moxifloxacin-containing arms vs no-moxifloxacin arms (p < 0.05). Patients receiving isoniazid reached a peak ALT >= 3 * ULN 9.5 days earlier than those on the ethambutol arm (median time of 28 days vs 18.5 days). Of the 67 Asian patients with a peak ALT/AST >= 3 * ULN, 57 (85.1%) were on an isoniazid containing regimen (p = 0.008). CONCLUSIONS: Our results provide evidence of the risk of DILI in tuberculosis patients on standard treatment. Older patients on standard therapy, HIV-positive patients, Asian patients and those receiving isoniazid were at higher risk of elevated enzyme levels. Monitoring hepatic enzymes during the first 2 months of standard therapy detected approximately 75% of patients with a peak enzyme elevation >=3 * ULN, suggesting this should be a standard of care. These results provide evidence for the potential of moxifloxacin in hepatic sparing. PMID- 29592806 TI - beta-aminoisobutyric acid attenuates LPS-induced inflammation and insulin resistance in adipocytes through AMPK-mediated pathway. AB - BACKGROUND: beta-aminoisobutyric acid (BAIBA) is produced in skeletal muscle during exercise and has beneficial effects on obesity-related metabolic disorders such as diabetes and non-alcoholic fatty liver disease. Thus, it is supposed to prevent high fat diet (HFD)-induced inflammation and insulin resistance in adipose tissue though anti-inflammatory effects in obesity. Previous reports have also demonstrated strong anti-inflammatory effects of BAIBA. METHODS: We used BAIBA treated fully differentiated 3T3T-L1 mouse adipocytes to investigate the effects of exogenous BAIBA on inflammation and insulin signaling in adipocytes. Insulin signaling-mediated proteins and inflammation markers were measured by Western blot analysis. Secretion of pro-inflammatory cytokines were measured by ELISA. Lipid accumulation in differentiated 3 T3-L1 cells was stained by Oil red O. Statistical analysis was performed by ANOVA and student's t test. RESULTS: BAIBA treatment suppressed adipogenesis assessed by adipogenic markers as well as lipid accumulation after full differentiation. We showed that BAIBA treatment stimulated AMP-activated protein kinase (AMPK) phosphorylation in a dose dependent manner and lipopolysaccharide (LPS)-induced secretion of pro inflammatory cytokines such as TNFalpha and MCP-1 was abrogated in BAIBA-treated 3 T3-L1 cells. Treatment of 3 T3-L1 cells with BAIBA reduced LPS-induced NFkappaB and IkappaB phosphorylation. Furthermore, BAIBA treatment ameliorated LPS-induced impairment of insulin signaling measured by IRS-1 and Akt phosphorylation and fatty acid oxidation. Suppression of AMPK by small interfering (si) RNA significantly restored these changes. CONCLUSIONS: We demonstrated anti inflammatory and anti-insulin resistance effects of BAIBA in differentiated 3 T3 L1 cells treated with LPS through AMPK-dependent signaling. These results provide evidence for the beneficial effects of BAIBA not only in liver and skeletal muscle cells but also in adipose tissue. PMID- 29592807 TI - Bursectomy for advanced gastric cancer: an update meta-analysis. AB - BACKGROUND: The present meta-analysis was to explore the surgical and oncological outcomes of bursectomy for advanced gastric cancer (AGC). METHODS: Relevant studies that evaluated the role of bursectomy for AGC were comprehensively examined to perform a meta-analysis. The primary outcomes were overall survival (OS) and disease-free survival (DFS). The secondary outcomes were the number of harvested lymph nodes (LNs), operation time, operative bleeding, hospital stay, postoperative complication and mortality. RESULTS: A total of seven studies comprising 2633 cases (1176 cases in the bursectomy group and 1457 cases in the non-bursectomy group) were finally included. There was no significant difference in OS (HR 0.95, P = 0.647) and DFS (HR 0.99, P = 0.936) between the two groups. Even for patients with serosa-penetrating tumours, OS was comparable between the two groups (HR 0.87, P = 0.356). The operation time of the bursectomy group was longer (weighted mean difference, WMD 32.76 min, P = 0.002). No significant difference was found between the two groups in terms of the number of dissected LNs (WMD 5.86, P = 0.157), operative bleeding (WMD 66.99 ml, P = 0.192) and hospital stay (WMD - 0.15 days, P = 0.766). The overall postoperative complication (relative risk, RR 1.08, P = 0.421) and mortality (RR 0.44, P = 0.195) were similar between two groups. CONCLUSIONS: This meta-analysis indicated that bursectomy is time-consuming without increasing the number of harvested LNs. Although bursectomy can be safely performed without increasing complications and mortality, it does not prolong the OS and DFS of AGC patients, including patients with serosa-penetrating tumours. Therefore, bursectomy should not be recommended as a standard procedure for AGC. PMID- 29592808 TI - Correction to: A sophisticated, differentiated Golgi in the ancestor of eukaryotes. AB - Upon publication of the original article, Barlow et al. [1], the authors noticed that Fig. 4b contained an inaccuracy when additional data is taken into account. We inferred a loss of GRASP in the common ancestor of cryptophytes and archaeplastids, based on the absence of identified homologues in the data from taxa that we analyzed, which include Cyanidioschyzon merolae as the single representative of red algae. PMID- 29592809 TI - Exploring the potential of black tea based flavonoids against hyperlipidemia related disorders. AB - BACKGROUND: In recent decade, Hyperlipidemia related disorders like obesity, hypercholesterolemia and diabetes are considered as the leading killers for mankind. Fundamental nexus between nutrition and health diverting the consumers focus towards plant based natural products as a remedy against various metabolic syndrome. Considering this, present study was conducted to explicate the role of black tea polyphenols such as Theaflavins and thearubigins therapeutic potential to tackle targeted maladies especially oxidative stress related disorders like hypercholesterolemia and diabetes. METHODS: The mandate of current investigation was to explore the hypoglycemic and hypocholestrolemic perspective of isolated theaflavin and thearubigins through a model feeding trial. For the purpose, theaflavin & thearubigins were isolated from black tea through solvent partition method and utilize to form three types of nutraceutical drinks (theaflavin, thearubigins & theaflavin + thearubigins based) alongside control to be further utilized in bioefficacy trial. In bioefficacy trial, three types of independent studies were design on the bases of diet by involving 20 male wistar rats in each study (5 for each group). In study I, normal diet was administrated while, in study II & III high cholesterol and high sucrose diet was given, respectively along with prepared nutraceutical drinks to synchronize their therapeutic effect for a period of 56 days. At the termination of trial, Feed & drink intakes, body weight, total cholesterol, LDL, HDL, triglycerides, glucose and insulin levels were measured. RESULTS: The results indicated reduction in cholesterol, LDL and triglycerides levels of experimental rats in all studies with significant increase in HDL. In this context, theaflavin based drink imparted maximum reduction in cholesterol (3.75, 11.03 & 10.39%), LDL (3.84, 14.25& 10.84%) & triglycerides (2.99, 8.54 & 6.65%) in respective studies compared to thearubigins and theaflavin + thearubigins based drinks. However, theaflavin+ thearubigins based drink caused highest glucose decline and maximum insulin increase in all studies as compared to other nutraceutical drinks. The reported value for the insulin increase were 13.02 +/- 1.02 & 14.55 +/- 1.13, 10.09 +/- 0.15 & 11.59 +/- 0.86 for Hyperglycemic and Hypocholestrolemic rats respectively compared to control (7.84 +/- 0.45 & 9.10 +/- 0.41) for study I and II. CONCLUSIONS: In the nutshell, theaflavin and thearubigins based dietary interventions are helpful to alleviate the hypercholestrolemia and hyperglycemia and should be promoted as parallel therapy to combat these disorders.

AB - Advances in Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR associated system (CRISPR/Cas9) has dramatically reshaped our ability to edit genomes. The scientific community is using CRISPR/Cas9 for various biotechnological and medical purposes. One of its most important uses is developing potential therapeutic strategies against diseases. CRISPR/Cas9 based approaches have been increasingly applied to the treatment of human diseases like cancer, genetic, immunological and neurological disorders and viral diseases. These strategies using CRISPR/Cas9 are not only therapy oriented but can also be used for disease modeling as well, which in turn can lead to the improved understanding of mechanisms of various infectious and genetic diseases. In addition, CRISPR/Cas9 system can also be used as programmable antibiotics to kill the bacteria sequence specifically and therefore can bypass multidrug resistance. Furthermore, CRISPR/Cas9 based gene drive may also hold the potential to limit the spread of vector borne diseases. This bacterial and archaeal adaptive immune system might be a therapeutic answer to previous incurable diseases, of course rigorous testing is required to corroborate these claims. In this review, we provide an insight about the recent developments using CRISPR/Cas9 against various diseases with respect to disease modeling and treatment, and what future perspectives should be noted while using this technology. PMID- 29592811 TI - Novel microtubule inhibitor MPT0B098 inhibits hypoxia-induced epithelial-to mesenchymal transition in head and neck squamous cell carcinoma. AB - BACKGROUND: Tumor hypoxia-induced epithelial-mesenchymal transition (EMT) is critical in promoting cancer metastasis. We recently discovered a novel microtubule inhibitor, MPT0B098, that employs a novel antitumor mechanism. It destabilizes hypoxia-inducible factor (HIF)-1alpha mRNA by blocking the function of human antigen R. Thus, we proposed that MPT0B098 modulates hypoxia-induced EMT. METHODS: In vitro IC50 values were determined through the methylene blue dye assay. To investigate molecular events, reverse transcriptase-polymerase chain reaction, Western blotting, immunofluorescence staining, and wound healing assay were employed. RESULTS: MPT0B098 significantly inhibited HIF-1alpha expression, epithelial-to-mesenchymal morphology changes, and migratory ability in the human head and neck squamous cell carcinoma cell line OEC-M1. Furthermore, after MPT0B098 treatment, the expression of two mesenchymal markers, vimentin and N cadherin, was downregulated under hypoxic conditions. Moreover, MPT0B098 suppressed hypoxia-induced EMT in part by inhibiting EMT-activating transcription factors, Twist and SNAI2/Slug. In addition, the inhibition of hypoxia-induced F actin rearrangement and focal adhesion kinase phosphorylation may have contributed to suppression of EMT by MPT0B098in OEC-M1 cells. MPT0B098 significantly inhibited transforming growth factor(TGF)-beta-induced phosphorylation of receptor-associated Smad2/3 by downregulating TGF-beta mRNA and protein expression. CONCLUSIONS: Taken together, this study provides a novel insight into the role of MPT0B098 in inhibiting hypoxia-induced EMT, suggesting its potential use for treating head and neck cancers. PMID- 29592812 TI - Discovery of physiological and cancer-related regulators of 3' UTR processing with KAPAC. AB - 3' Untranslated regions (3' UTRs) length is regulated in relation to cellular state. To uncover key regulators of poly(A) site use in specific conditions, we have developed PAQR, a method for quantifying poly(A) site use from RNA sequencing data and KAPAC, an approach that infers activities of oligomeric sequence motifs on poly(A) site choice. Application of PAQR and KAPAC to RNA sequencing data from normal and tumor tissue samples uncovers motifs that can explain changes in cleavage and polyadenylation in specific cancers. In particular, our analysis points to polypyrimidine tract binding protein 1 as a regulator of poly(A) site choice in glioblastoma. PMID- 29592813 TI - Cancer Genome Interpreter annotates the biological and clinical relevance of tumor alterations. AB - While tumor genome sequencing has become widely available in clinical and research settings, the interpretation of tumor somatic variants remains an important bottleneck. Here we present the Cancer Genome Interpreter, a versatile platform that automates the interpretation of newly sequenced cancer genomes, annotating the potential of alterations detected in tumors to act as drivers and their possible effect on treatment response. The results are organized in different levels of evidence according to current knowledge, which we envision can support a broad range of oncology use cases. The resource is publicly available at http://www.cancergenomeinterpreter.org . PMID- 29592814 TI - QAPA: a new method for the systematic analysis of alternative polyadenylation from RNA-seq data. AB - Alternative polyadenylation (APA) affects most mammalian genes. The genome-wide investigation of APA has been hampered by an inability to reliably profile it using conventional RNA-seq. We describe 'Quantification of APA' (QAPA), a method that infers APA from conventional RNA-seq data. QAPA is faster and more sensitive than other methods. Application of QAPA reveals discrete, temporally coordinated APA programs during neurogenesis and that there is little overlap between genes regulated by alternative splicing and those by APA. Modeling of these data uncovers an APA sequence code. QAPA thus enables the discovery and characterization of programs of regulated APA using conventional RNA-seq. PMID- 29592815 TI - Treatment optimization of angiotensin converting enzyme inhibitors and associated factors in Ayder Comprehensive Specialized Hospital: a cross-sectional study. AB - BACKGROUND: Angiotensin-converting enzyme inhibitors have morbidity and mortality benefits in heart failure. Failure to optimize treatment using these medications increases hospitalizations, worsens signs and symptoms of heart failure, and reduces the overall treatment outcome. Therefore, the main purpose of this study was to assess the practice of treatment optimization of these medications and associated factors. RESULTS: A hospital-based cross-sectional study was conducted on 61 ambulatory heart failure patients, recruited using a convenience sampling technique, from February 25 to May 24, 2016 at the cardiology clinic of Ayder Comprehensive Specialized Hospital. Descriptive, inferential and Kaplan-Meier 'tolerability' analyses were employed. All patients were taking only enalapril as part of their angiotensin converting enzyme inhibitor treatment. According to the 2013 American College of Cardiology/American Heart Association guideline, about fourth-fifth (80.3%) of the patients were tolerating to the hypotensive effect of enalapril. The dose of enalapril was timely titrated (every 2-4 weeks) and was optimized for only 11.5 and 27.8% of the patients, respectively. Considering the tolerance, timely titration, and dose optimization, only 3.3% of the overall enalapril treatment was optimized. Multivariate regression results showed that the odds of having timely titration of enalapril for patients who were taking enalapril and calcium channel blockers were almost 20 times [adjusted odds ratio (AOR) = 21.68, 95% confidence interval (CI) 1.23-383.16, p < 0.036] more compared to patients who were taking enalapril and beta-blockers. A Log Rank Chi Square result showed a 19.42 magnitude of better toleration of enalapril (p < 0.001) for patients who were taking enalapril for more than 1 year compared to less than a year. CONCLUSION: This study provides a platform for assessment of the treatment optimization practice of enalapril, which remains the pressing priority and found to be poor in the ambulatory setting, despite a better tolerability to the hypotensive effect of enalapril. We call for greater momentum of efforts by health care providers in optimizing the treatment practice to benchmark with other optimization practices. PMID- 29592816 TI - The Abeta protofibril selective antibody mAb158 prevents accumulation of Abeta in astrocytes and rescues neurons from Abeta-induced cell death. AB - BACKGROUND: Currently, several amyloid beta (Abeta) antibodies, including the protofibril selective antibody BAN2401, are in clinical trials. The murine version of BAN2401, mAb158, has previously been shown to lower the levels of pathogenic Abeta and prevent Abeta deposition in animal models of Alzheimer's disease (AD). However, the cellular mechanisms of the antibody's action remain unknown. We have recently shown that astrocytes effectively engulf Abeta42 protofibrils, but store rather than degrade the ingested Abeta aggregates. In a co-culture set-up, the incomplete degradation of Abeta42 protofibrils by astrocytes results in increased neuronal cell death, due to the release of extracellular vesicles, containing N-truncated, neurotoxic Abeta. METHODS: The aim of the present study was to investigate if the accumulation of Abeta in astrocytes can be affected by the Abeta protofibril selective antibody mAb158. Co cultures of astrocytes, neurons, and oligodendrocytes, derived from embryonic mouse cortex, were exposed to Abeta42 protofibrils in the presence or absence of mAb158. RESULTS: Our results demonstrate that the presence of mAb158 almost abolished Abeta accumulation in astrocytes. Consequently, mAb158 treatment rescued neurons from Abeta-induced cell death. CONCLUSION: Based on these findings, we conclude that astrocytes may play a central mechanistic role in anti Abeta immunotherapy. PMID- 29592817 TI - Dysregulation of chemokine receptor expression and function in leukocytes from ALS patients. AB - Amyotrophic lateral sclerosis (ALS) is rapidly progressive adult-onset motor neuron disease characterized by the neurodegeneration of both upper and lower motor neurons in the cortex and the spinal cord; the majority of patients succumb to respiratory failure. Although the etiology is not yet fully understood, there is compelling evidence that ALS is a multi-systemic disorder, with peripheral inflammation critically contributing to the disease process. However, the full extent and nature of this immunological dysregulation remains to be established, particularly within circulating blood cells. Therefore, the aim of the present study was to identify dysregulated inflammatory molecules in peripheral blood cells of ALS patients and analyze for functional consequences of the observed findings. To this end, we employed flow cytometry-based screening to quantify the surface expression of major chemokine receptors and integrins. A significantly increased expression of CXCR3, CXCR4, CCL2, and CCL5 was observed on T cells in ALS patients compared to healthy controls. Intriguingly, the expression was even more pronounced in patients with a slow progressive phenotype. To further investigate the functional consequences of this altered surface expression, we used a modified Boyden chamber assay to measure chemotaxis in ALS patient-derived lymphocytes. Interestingly, chemoattraction with the CXCR3-Ligand IP10 led to upregulated migratory behavior of ALS lymphocytes compared to healthy controls. Taken together, our data provides evidence for a functional dysregulation of IP10 directed chemotaxis in peripheral blood cells in ALS patients. However, whether the chemokine itself or its receptor CXCR3, or both, could serve as potential therapeutic targets in ALS requires further investigations. PMID- 29592819 TI - Editorial. PMID- 29592820 TI - Outsourcing critical financial system operations. AB - Payments Canada provides Canada's national payments systems and is responsible for the clearing and settlement infrastructure, processes and rules that underpin the exchange of billions of dollars each day through the Canadian economy. Strategic sourcing is a reality for this small organisation with a broad scope of national regulations and global standards to comply with. This paper outlines Payments Canada's approach to outsourcing its critical financial system operations, which centres on four key principles: strong relationship management; continuous learning, recording and reporting; evaluating the business landscape; and a commitment to evolving the organisation to greater resilience. This last point is covered in detail with an exploration of the organisation's resilience and security strategy as well as its risk appetite. As Payments Canada progresses to its future state, which includes modernising its core payment systems, underlying rules and standards, risk management for the industry as a whole will remain at the forefront of its collective mind. The expectation is that outsourcing will remain a fundamental element of its operating model in future, a strategy that will ensure the organisation can focus on its core business competencies and eliminate the need to develop and support in-house expertise in commodity areas. PMID- 29592818 TI - Social-support needs among adolescents living with HIV in transition from pediatric to adult care in Cambodia: findings from a cross-sectional study. AB - BACKGROUND: Understanding the circumstances of adolescents living with HIV is critical in designing adolescent-friendly services that will facilitate successful transition from pediatric to adult care. This study describes access, utilization and ongoing social support needs among adolescents living with HIV aged 15-17 in transition from pediatric to adult HIV care in Cambodia. METHODS: A cross-sectional study was conducted among 328 adolescents, randomly selected from 11 antiretroviral therapy (ART) clinics across the country. Descriptive analyses were conducted to summarize their characteristics, access to social support and ongoing support needs among male and female adolescents. RESULTS: Mean age of the study participants was 15.8 (SD = 0.8) years. Just over half (55.2%) were male. Most had at least one deceased parent (mother 50.9%; father 60.5%), and majority were living with biological parents (40.8%) or relatives (49.3%). A third came from families with an ID poor card, and 21.0% were working for pay. Almost half (46.6%) reported that their family had received social support for their health care, including food support (76.5%), school allowance (62.1%), transport allowance to ART clinics (53.6%), psychosocial counseling (35.3%), vocational training (22.9%) or home visits (11.1%). Several ongoing social support needs were identified, including ongoing inability to cover health expenses unless they are supported by health insurance or health equity fund (55.0%). In addition, adolescents reported having been asked to come back earlier than their scheduled appointment (13.7%), having had to purchase their own drugs (2.7%), experiencing HIV stigma (32.0%), having been denied housing or food due to HIV (8.2%) or failing to attend school within the past month partly because of HIV (16.8%). Two thirds did not have access to peer support groups. CONCLUSIONS: Social protection mechanisms are reaching some adolescents in need, while other remain without social support due to discontinuities in health and social care. Multi-sectoral interventions, supporting school attendance, adolescent-friendly clinic scheduling, reductions in child employment, mitigation of HIV-related stigma and strengthening of peer-to-peer support are required to improve coverage of social protection interventions for adolescents in transition. PMID- 29592821 TI - Preparing for campus demonstrations and protests: Four key focus areas. AB - Over the past few years, the number of demonstrations and protests in Western countries has been increasing. These protests have tested the limits of free speech and expression, leading to individuals and groups attempting to, and in some cases succeeding in, shutting down speech with which they do not agree or find offensive. This has been particularly acute on college campuses, most notably at the University of California, Berkeley and Auburn University in Alabama, where speakers with far-right conservative views were forced to cancel their planned speeches because of safety and security concerns. As a result, colleges and universities throughout the USA are re-examining their policies and procedures for speaking engagements and demonstrations and protests, and how to manage them effectively while keeping their campus communities safe. This paper suggests methods by which universities can put into place policies, procedures and guidelines to minimise the possibility of an event becoming violent and overwhelming university resources while at the same time balancing the need for security and an environment that promotes the free exchange of ideas and expression. PMID- 29592822 TI - The true value and return on investment of business continuity. AB - The phrase return on investment (ROI) is commonly heard when groups or organisations attempt to demonstrate the value of a particular activity. 'Is it good for us?', 'Is it worth the investment?' and 'Should we continue to fund the endeavour?' are all valid and important questions. The challenge for business continuity professionals is to address the question, 'What is the ROI of business continuity?' in ways that will be meaningful to the person wielding the budget stick. In the 'olden days', colleagues would point to their business impact analysis, with pie charts and bar graphs showing the cost of business downtime if an event occurred. They would sit back and say, 'See? We provide ROI because we addressed The Bad Thing!'. But is that really the best that continuity professionals can do? This paper peels back the question of ROI and addresses the value proposition of business continuity. The goal is to broaden the conversation, by instead of talking about how much money business continuity efforts will save the company, and instead to focus on the value that business continuity provides every day. PMID- 29592823 TI - Business continuity and risk management at a strategic level: Case study of the Flemish government. AB - The Flemish government comprises a number of different departments and agencies with the autonomy to optimise their service level in a proactive and resilient manner. Recently, the Flemish government defined four organisational values: openness, decisiveness, trust and agility. In addition, the Internal Audit Agency developed guidelines concerning internal control and organisational management, in which risk management was emphasised. In combination with goal setting and process management, this paper considers risk management as a starting point for the overall management of Flemish government entities. The paper then develops tools to support the establishment of business continuity and risk management processes. These tools fit into the organisation's strategic framework and are easy to understand, pragmatically designed and flexible in their use. The paper goes on to illustrate how the Department of the Chancellery and Public Governance is implementing BCM and risk management, and how it is integrating BCM, risk management and crisis management. It will then focus on the Flemish government's long-term strategy across the boundaries between the different entities and the question of how risk management can become a useful tool for policy makers. PMID- 29592824 TI - A customer-insight led approach to building operational resilience. AB - High-profile failures over the past few years have led to the disruption of banking services in the UK, with some banks' customers left unable to make or receive payments, check balances or access cash for days or weeks. Technological advances and a push towards remote channels have increased customer expectations of 'always on' - any time, any place, anywhere - and with disruptions lasting anything from a few minutes to nearly a month, the regulator is also taking an interest. Nationwide Building Society has responded positively to this challenge by defining its operational resilience strategy, a long-term plan aimed at minimising the likelihood and impact of future disruptions. Customer research was used in order to understand customer expectations, as well as define and prioritise its end-to-end customer journeys, known as business service lines. A comprehensive mapping exercise facilitated the development of strategies and investment projects to address identified vulnerabilities and increase resilience. PMID- 29592825 TI - Business continuity and disaster management within the public service in relation to a national development plan. AB - Within South Africa, few public service departments understand the concepts of business continuity management (BCM) and what it takes to implement a well constructed business continuity plan. Likewise, few of these entities understand the purpose of designing and maintaining resilient systems that are immune to incidents. This paper discusses the integration of the South African Disaster Management Act 2002, the Disaster Management Framework and the National Development Plan, linking these to BCM, through a resilience period model, as a means for the implementation of resilience strategies. The goals of the National Development Plan are outlined with a view to how resilience can be achieved in each. A resilience period model has been advocated for the implementation of projects within the public sector in order to provide continuity and sustainability.

This paper suggests some points for consideration and implementation. PMID- 29592827 TI - Managing stress in a crisis. AB - Crisis situations are inherently uncertain and threatening. Although the primal stress reactions they provoke deliver some advantages, they so severely restrict intellect and behaviour that consultants observe crisis teams making the same mistakes over and again. Stress risks can be managed before, during and after a crisis. Crisis planning can select the right people, control the crisis team environment, and mitigate fatigue risks and memory demands. Because stress reactions are primitive, stress can be manipulated at a remarkably primitive level and teams can increase their resilience through such basics as sleep and breathing skills. Teams can learn to manipulate perceptions of danger, to tolerate uncertainty and to become comfortable making decisions which were reasonable at the time. Crisis leaders can frame the crisis as a challenge and options as gains, and can ensure the team avoids groupthink and challenges the paradigm. Where individuals are trained to apply critical thinking processes, intuitive decision-making is not only fast, but also accurate, and helps to challenge assumptions, predictions and groupthink. Crises are more easily recognised and managed where training has covered critical decision methods. PMID- 29592828 TI - Improving disaster outcomes with better decision making. AB - Decisions made in an emergency can improve or exacerbate the outcome of the event. Making complex decisions in high-stress circumstances is not easily done without prior training. Understanding how people process information under stress, and how decisions are affected by bias, can lead to better decision making. This paper examines how risk communication lessons from sense-making research and cockpit resource management can be applied to business and industry to improve emergency and disaster outcomes. PMID- 29592829 TI - Low levels of chemsex among men who have sex with men, but high levels of risk among men who engage in chemsex: analysis of a cross-sectional online survey across four countries. AB - : Background This paper establishes the prevalence of chemsex drug use among men who have sex with men (MSM), the extent to which these drugs are used in a sexual context, as well as their associated behaviours and circumstances of use. METHODS: Data from a cross-sectional, online survey of 2328 MSM recruited via gay sociosexual media in Scotland, Wales, Northern Ireland and the Republic of Ireland were analysed. RESULTS: While almost half (48.8%) of participants had ever taken illicit drugs, lifetime chemsex drug use was less common (18.0%) and far fewer reported chemsex drug use in the last year (8.2%) or last 4 weeks (3.0%). Just over one-quarter (27.1%) of men who used chemsex drugs in the last year reported no sexualised drug use, but almost three-quarters (72.9%) did. Only 6.1% of the whole sample reported sexualised chemsex drug use in the last year. The odds of reporting chemsex in the last year were significantly higher for men aged 36-45 years (AOR=1.96), single men (AOR=1.83), men who were HIV positive (AOR=4.01), men who report high-risk sex (AOR=4.46), being fisted (AOR=7.77) or had sex in exchange for goods other than money (AOR=4.7) in the last year and men who reported an HIV test in the last 3 months (AOR=1.53). DISCUSSION: Only a small proportion of MSM in Scotland, Wales, Northern Ireland and the Republic of Ireland reported chemsex, and, for the first time, it is demonstrated that not all chemsex drug use was sexualised. Nevertheless, MSM who engage in chemsex (MWEC) reported substantial sexual risk inequalities. These novel findings highlight several opportunities for intervention, particularly around the multiple vulnerabilities of MWEC, opportunities for early identification of those most vulnerable to chemsex-related harm and the potential to develop a specialised responsive patient pathway. PMID- 29592830 TI - A community-led, harm-reduction approach to chemsex: case study from Australia's largest gay city. AB - Rates of drug use remain substantially higher among gay and bisexual men (GBM) and people living with HIV (PLHIV) in Sydney, New South Wales, Australia. The use of drugs to enhance sexual pleasure within cultures of Party and Play creates opportunities to discuss sexual health, mental health, consent and wellbeing. Community organisations with a history of HIV prevention, care, treatment are well-placed to respond. ACON's (formerly the AIDS Council of New South Wales) multi-dimensional response to 'chemsex' includes: direct client services support for individuals seeking to manage or reduce their use; health promotion activities that support peer education; partnerships with research institutions to better understand cultures of chemsex; and policy submissions that call for drug use to be approached as a health, rather than a criminal, issue. The approach speaks the language of Party and Play subcultures; employs culturally relevant terminology and imagery; uses content designed, created and delivered by peers; and operates within a pleasure-positive, harm-reduction and community-led framework. These interventions have led to increased service uptake, strong community engagement, robust research partnerships and the recognition of GBM as a priority population in relevant strategies.

AB - BACKGROUND: Antimicrobial therapy is among the mainstream treatment modalities employed in clinical settings. Antimicrobial sensitivity of the pathogen and patient compliance are key determinants of the efficacy of antimicrobial therapy. OBJECTIVE: In this study, we sought to investigate the factors that affect patient compliance to antimicrobial therapy in a Chinese teaching hospital to enhance patient compliance and to prevent abuse and misuse of antibiotics by patients. METHODS: A questionnaire survey was conducted among patients willing to answer all the questions who were prescribed antimicrobial drugs orally, and for whom at least half of the duration of therapy was not under the supervision of a doctor or nurse. Data analyses were performed using Kruskal-Wallis test and multivariate logistic regression. RESULTS: A total of 720 patients participated in the survey; of these, 714 patients provided complete data and were included in the analysis. Up to 86.97% of patients showed noncompliance to antimicrobial therapy (total compliance score < 8), whereas 13.03% of patients showed good compliance (total compliance score = 8). On multivariate analyses, understanding of the treatment was an important factor associated with compliance. CONCLUSIONS: A range of factors were associated with compliance to antimicrobial therapy, including understanding of the treatment, gender, age, home address, education level, and family income.

PMID- 29592837 TI - A proposal for antifungal epidemiological cut-off values against Histoplasma capsulatum var. capsulatum based on the susceptibility of isolates from HIV infected patients with disseminated histoplasmosis in Northeast Brazil. AB - Epidemiological cut-off values (ECVs) have been used as a tool to detect the acquisition of resistance mechanisms to antifungal drugs. In this context, the objective of this study was to determine the ECVs for classic antifungals against Histoplasma capsulatum var. capsulatum isolates from human immunodeficiency virus (HIV)-infected patients with a diagnosis of disseminated histoplasmosis. First, minimum inhibitory concentrations (MICs) for amphotericin B (AmB), itraconazole (ITR), fluconazole (FLU), voriconazole (VCZ) and caspofungin (CAS) were determined against 138 H. capsulatum isolates in the filamentous form by the broth microdilution method; antifungal ECVs were then calculated. MIC ranges were 0.0078-1 ug/mL for AmB, 0.0005-0.0625 ug/mL for ITR, 2 to >=256 ug/mL for FLU, 0.0078-1 ug/mL for VCZ and <=0.0156 to >=32 ug/mL for CAS. The obtained ECVs were 0.5, 0.0313, 128, 0.5 and 16 ug/mL for AmB, ITR, FLU, VCZ and CAS, respectively. The percentage of wild-type isolates was 96.4% for AmB, 98.6% for ITR and 99.3% for FLU, VCZ and CAS. Although these results do not cover all phylogenetic species of H. capsulatum, they bring important information on strains from Brazil. In addition, the assessed isolates were from HIV-positive patients, which may not reflect the antifungal ECVs against isolates from immunocompetent individuals or from other sources. Finally, this study pioneers the initiative of establishing ECVs for five antifungal agents against H. capsulatum var. capsulatum, providing a criterion for the interpretation of susceptibility results as well as a monitoring strategy for the emergence of antifungal resistance.

This is the first report on USUV in mosquitoes from France that concurrently accompanied the emergence of Usutu virus in blackbirds and a human case in France during 2015/2016. PMID- 29592839 TI - High resolution mass spectrometry-based methodologies for identification of Etravirine bioactivation to reactive metabolites: In vitro and in vivo approaches. AB - Drug bioactivation to reactive metabolites capable of covalent adduct formation with bionucleophiles is a major cause of drug-induced adverse reactions. Therefore, elucidation of reactive metabolites is essential to unravel the toxicity mechanisms induced by drugs and thereby identify patient subgroups at higher risk. Etravirine (ETR) was the first second-generation Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) to be approved, as a therapeutic option for HIV-infected patients who developed resistance to the first-generation NNRTIs. Additionally, ETR came into market aiming to overcome some adverse effects associated with the previously used efavirenz (neurotoxicity) and nevirapine (hepatotoxicity) therapies. Nonetheless, post-marketing reports of severe ETR-induced skin rash and hypersensitivity reactions have prompted the U.S. FDA to issue a safety alert on ETR. Taking into consideration that ETR usage may increase in the near future, due to the possible use of the drug for coinfection with malaria and HIV, the development of reliable prognostic tools for early risk/benefit estimations is urgent. In the current study, high resolution mass spectrometry-based methodologies were integrated with MS3 experiments for the identification of reactive ETR metabolites/adducts: 1) in vitro incubation of the drug with human and rat liver S9 fractions in the presence of Phase I and II co-factors, including glutathione, as a trapping bionucleophile; and 2) in vivo, using urine samples from HIV-infected patients on ETR therapy. We obtained evidence for multiple bioactivation pathways leading to the formation of covalent adducts with glutathione and N-acetyl-L-cysteine. These results suggest that similar reactions may occur with cysteine residues of proteins, supporting a role for ETR bioactivation in the onset of the toxic effects elicited by the drug. Additionally, ETR metabolites stemming from amine oxidation, with potential toxicological significance, were identified in vitro and in vivo. Also noteworthy is the fact that new metabolic conjugation pathways of glucuronide metabolites were demonstrated for the first time, raising questions about their potential toxicological implications. In conclusion, these results represent not only a contribution towards the elucidation of new metabolic pathways of drugs in general but also an important step towards the elucidation of potentially toxic ETR pathways, whose understanding may be crucial for reliable risk/benefit estimations of ETR-based regimens. PMID- 29592841 TI - Will NNRTIs be driving forward again? PMID- 29592842 TI - Mirror Movements are Linked to Executive Control in Healthy and Brain-injured Adults. AB - It has been shown that brain-injured patients (BIP) have exacerbated mirror movements (MM). MM are involuntary contractions occurring in homologous muscles contralateral to voluntary movements, particularly in distal upper limb muscles. Attentional and inhibitory processes have been proposed as key factors to explain the level of MM. However, the link between MM and attentional/inhibitory processes has never been formally tested. The present study aims to test this link in 24 right-handed healthy adults and eight chronic BIP. We investigated the link between the amount/intensity of MM and attentional/inhibitory functions. For each participant, MM produced on each limb were assessed with two tasks, and the attentional and inhibitory functions were assessed with six neuropsychological tests. Our results showed (1) a greater amount and intensity of MM and (2) a selective deficit in sustained attention in BIP compared to healthy adults. Moreover, (3) in all participants - independent of the type of task used to evaluate MM - the amount and intensity of MM was predicted by the level of executive control, assessed by the Trail Making Test. High level of MM was associated with weak executive control abilities. This study is the first to highlight the link between MM and executive functioning, which may have implications for rehabilitation in BIP. PMID- 29592843 TI - Phosphorylated alpha-Synuclein Accumulations and Lewy Body-like Pathology Distributed in Parkinson's Disease-Related Brain Areas of Aged Rhesus Monkeys Treated with MPTP. AB - Phosphorylation of alpha-synuclein at serine 129 (P-Ser 129 alpha-syn) is involved in the pathogenesis of Parkinson's disease (PD) and Lewy body (LB) formation. However, there is no clear evidence indicates the quantitative relation of P-Ser 129 alpha-syn accumulation and dopaminergic cell loss, LBs pathology and the affected brain areas in PD monkeys. Here, pathological changes in the substantia nigra (SN) and PD-related brain areas were measured in aged monkeys treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) utilizing a modeling-recovery-remodeling strategy. Compared to age-matched controls, the MPTP-treated monkeys showed significantly reduced tyrosine hydroxylase (TH)-positive neurons and increased P-Ser 129 alpha-syn-positive aggregations in the SN. Double-labeling Immunofluorescence found some TH-positive neurons to be co-localized with P-Ser129 alpha-syn in the SN, suggesting the inverse correlation between P-Ser 129 alpha-syn aggregations and dopaminergic cell loss in the SN may represent an interactive association related to the progression of the PD symptoms in the model. P-Ser 129 alpha-syn aggregations or LB-like pathology was also found in the midbrain and the neocortex, specifically in the oculomotor nucleus (CN III), temporal cortex (TC), prefrontal cortex (PFC) and in cells surrounding the third ventricle. Notably, the occipital cortex (OC) was P-Ser 129 alpha-syn negative. The findings of LB-like pathologies, dopaminergic cell loss and the stability of the PD symptoms in this model suggest that the modeling-recovery-remodeling strategy in aged monkeys may provide a new platform for biomedical investigations into the pathogenesis of PD and potential therapeutic development. PMID- 29592840 TI - Doravirine versus ritonavir-boosted darunavir in antiretroviral-naive adults with HIV-1 (DRIVE-FORWARD): 48-week results of a randomised, double-blind, phase 3, non-inferiority trial. AB - BACKGROUND: Doravirine is a novel non-nucleoside reverse transcriptase inhibitor (NNRTI) with a pharmacokinetic profile supporting once-daily dosing, and potent in-vitro activity against the most common NNRTI-resistant HIV-1 variants. We compared doravirine with ritonavir-boosted darunavir, when both were given with two nucleoside reverse transcriptase inhibitors (NRTIs), in adults with previously untreated HIV-1 infection. METHODS: In this randomised, controlled, double-blind, multicentre, non-inferiority trial, adults with HIV-1 infection were screened and enrolled at 125 clinical centres in 15 countries. Eligible participants (aged >=18 years) were naive to antiretroviral therapy with plasma HIV-1 RNA of at least 1000 copies per mL at screening. Participants who had previously been treated for a viral infection other than HIV-1, those taking immunosuppressive drugs, and individuals with active acute hepatitis were excluded. Participants were randomly assigned (1:1) via an interactive voice and web response system to receive oral doravirine 100 mg or darunavir 800 mg plus ritonavir 100 mg once daily, with two investigator-selected NRTIs (tenofovir and emtricitabine or abacavir and lamivudine) for up to 96 weeks. Randomisation was stratified by HIV-1 RNA measurements at screening (<=100 000 vs >100 000 copies per mL) and the NRTI pair. Study participants, funding institution staff, investigators, and study site personnel were masked to treatment group assignment. The primary efficacy endpoint was the proportion of participants achieving HIV-1 RNA of less than 50 copies per mL at week 48 defined by the US Food and Drug Administration snapshot algorithm, with non-inferiority established if the lower bound of the two-sided 95% CI for the treatment difference (doravirine minus darunavir) was greater than -10 percentage points. All participants who received at least one dose of study drug were included in the primary efficacy and safety analyses. This trial is active, but not recruiting, and is registered with ClinicalTrials.gov, number NCT02275780. FINDINGS: Between Dec 1, 2014, and Oct 20, 2015, 1027 participants were screened for eligibility, of whom 769 participants were randomly assigned to treatment (385 with doravirine and 384 with ritonavir-boosted darunavir). 56 participants discontinued treatment in the doravirine group compared with 71 in the darunavir group, mostly due to loss to follow-up. 383 participants who received doravirine and 383 who received darunavir were included in the primary efficacy analyses. At week 48, 321 (84%) participants in the doravirine group and 306 (80%) in the darunavir group achieved plasma HIV-1 RNA of less than 50 copies per mL (difference 3.9%, 95% CI 1.6 to 9.4), indicating non-inferiority of the doravirine regimen. The most common study drug-related adverse events were diarrhoea (21 [5%] of 383 participants in the doravirine group and 49 [13%] of 383 participants in the darunavir group), nausea (25 [7%] vs 29 [8%]), and headache (23 [6%] vs ten [3%]). 18 participants (six [2%] of 383 participants in the doravirine group vs 12 [3%] of 383 participants in the darunavir group) discontinued treatment due to adverse events, which were considered drug-related in four (1%) participants in the doravirine group and 8 (2%) participants in the darunavir group. Serious adverse events occurred in 19 (5%) of 383 participants in the doravirine group and 23 (6%) of 383 in the darunavir roup, and were considered study-drug related in one (<1%) participant of each group. INTERPRETATION: In treatment-naive adults with HIV-1 infection, doravirine combined with two NRTIs might offer a valuable treatment option for adults with previously untreated HIV-1 infection.

AB - Emerging evidence suggests that acupuncture treatment has anti-oxidative effects that affect cognitive impairment in vascular dementia (VD) rats. In the present study, we aimed to investigate whether thioredoxin-1 (Trx-1)/thioredoxin reductase-1 (TrxR-1) was involved in the beneficial effects of acupuncture. After 2-weeks of acupuncture treatment, Morris water maze (MWM), dihydroethidium (DHE) staining, Nissl staining and TdT-mediated dUTP nick end labeling (TUNEL) staining were used to assess the effects of acupuncture on cognitive function and hippocampal neuronal injury in two-vessel occlusion (2VO) model. The protein and mRNA levels of Trx-1 and TrxR-1, the activity of TrxR-1 as well as the phosphorylation of the apoptosis signal-regulating kinase 1 (ASK1)-c-Jun N terminal kinase (JNK)/p38 pathway were measured by Western blot, real-time PCR analysis, TrxR-1 activity analysis and immunofluorescence (IF) staining respectively. We found that there were oxidative and apoptotic injury in the CA1 area, accompanied with the decreased expressions of Trx-1 and TrxR-1 in the hippocampus. Acupuncture ameliorated cognitive deficits caused by cerebral ischemic injury and inhibited oxidative stress and neuronal apoptotic injury in the hippocampus. Acupuncture also up-regulated the expressions of Trx-1 and TrxR 1, increased the activity of TrxR-1, accompanied with inhibiting the activation of the ASK1-JNK/p38 pathway. However, the effects of acupuncture on improving cognitive function, inhibiting oxidative stress and neuron apoptotic damage were blocked by Trx-1siRNA. In conclusion, these findings indicated that acupuncture treatment improved VD though anti-oxidative and anti-apoptotic mechanisms which involved the up-regulations of Trx-1/TrxR-1 and inhibitions of ASK1-JNK/p38 pathway. PMID- 29592845 TI - Use of Social Network Sites for Communication Among Health Professionals: Systematic Review. AB - BACKGROUND: Although much research has been done investigating the roles of social network sites (SNSs) in linking patients and health professionals, there is a lack of information about their uses, benefits, and limitations in connecting health professions only for professional communication. OBJECTIVE: This review aimed to examine the utilization of SNSs for communication among health professionals in (1) frontline clinical practice, (2) professional networks, and (3) education and training to identify areas for future health communication research. METHODS: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A systematic search of the literature published in the last 10 years (January 1, 2007, to March 1, 2017) was performed in March 2017, using the following electronic databases: MEDLINE via OvidSP, EMBASE, CINAHL Complete, and InfoSci-Journals. The searches were conducted using the following defined search terms: "social media" OR "social network" OR "social network site" OR "Facebook" OR "Twitter" OR "Linkedin" OR "Instagram" OR "Weibo" OR "Whatsapp" OR "Telegram" OR "WeChat" AND "health" OR "health profession." RESULTS: Of the 6977 papers retrieved, a total of 33 studies were included in this review. They were exploratory in nature, and the majority used surveys (n=25) and interviews (n=6). All retrieved studies stated that SNSs enhanced effective communication and information sharing. SNSs were used for supporting delivering of clinical services, making referrals, and sharing information. They were beneficial to network building and professional collaboration. SNSs were novel tools to enhance educational interactions among peers, students, instructors, and preceptors. The application of SNSs came with restraints in technical knowledge, concerns on data protection, privacy and liability, issues in professionalism, and data protection. CONCLUSIONS: SNSs provide platforms facilitating efficient communication, interactions, and connections among health professionals in frontline clinical practice, professional networks, education, and training with limitations identified as technical knowledge, professionalism, and risks of data protection. The evolving use of SNSs necessitates robust research to explore the full potential and the relative effectiveness of SNSs in professional communication. PMID- 29592846 TI - Evaluating an mHealth App for Health and Well-Being at Work: Mixed-Method Qualitative Study. AB - BACKGROUND: To improve workers' health and well-being, workplace interventions have been developed, but utilization and reach are unsatisfactory, and effects are small. In recent years, new approaches such as mobile health (mHealth) apps are being developed, but the evidence base is poor. Research is needed to examine its potential and to assess when, where, and for whom mHealth is efficacious in the occupational setting. To develop interventions for workers that actually will be adopted, insight into user satisfaction and technology acceptance is necessary. For this purpose, various qualitative evaluation methods are available. OBJECTIVE: The objectives of this study were to gain insight into (1) the opinions and experiences of employees and experts on drivers and barriers using an mHealth app in the working context and (2) the added value of three different qualitative methods that are available to evaluate mHealth apps in a working context: interviews with employees, focus groups with employees, and a focus group with experts. METHODS: Employees of a high-tech company and experts were asked to use an mHealth app for at least 3 weeks before participating in a qualitative evaluation. Twenty-two employees participated in interviews, 15 employees participated in three focus groups, and 6 experts participated in one focus group. Two researchers independently coded, categorized, and analyzed all quotes yielded from these evaluation methods with a codebook using constructs from user satisfaction and technology acceptance theories. RESULTS: Interviewing employees yielded 785 quotes, focus groups with employees yielded 266 quotes, and the focus group with experts yielded 132 quotes. Overall, participants muted enthusiasm about the app. Combined results from the three evaluation methods showed drivers and barriers for technology, user characteristics, context, privacy, and autonomy. A comparison between the three qualitative methods showed that issues revealed by experts only slightly overlapped with those expressed by employees. In addition, it was seen that the type of evaluation yielded different results. CONCLUSIONS: Findings from this study provide the following recommendations for organizations that are planning to provide mHealth apps to their workers and for developers of mHealth apps: (1) system performance influences adoption and adherence, (2) relevancy and benefits of the mHealth app should be clear to the user and should address users' characteristics, (3) app should take into account the work context, and (4) employees should be alerted to their right to privacy and use of personal data. Furthermore, a qualitative evaluation of mHealth apps in a work setting might benefit from combining more than one method. Factors to consider when selecting a qualitative research method are the design, development stage, and implementation of the app; the working context in which it is being used; employees' mental models; practicability; resources; and skills required of experts and users. PMID- 29592847 TI - Investigating the Extent to Which Patients Should Control Access to Patient Records for Research: A Deliberative Process Using Citizens' Juries. AB - BACKGROUND: The secondary use of health data for research raises complex questions of privacy and governance. Such questions are ill-suited to opinion polling where citizens must choose quickly between multiple-choice answers based on little information. OBJECTIVE: The aim of this project was to extend knowledge about what control informed citizens would seek over the use of health records for research after participating in a deliberative process using citizens' juries. METHODS: Two 3-day citizens' juries, of 17 citizens each, were convened to reflect UK national demographics from 355 eligible applicants. Each jury addressed the mission "To what extent should patients control access to patient records for secondary use?" Jurors heard from and questioned 5 expert witnesses (chosen either to inform the jury, or to argue for and against the secondary use of data), interspersed with structured opportunities to deliberate among themselves, including discussion and role-play. Jurors voted on a series of questions associated with the jury mission, giving their rationale. Individual views were polled using questionnaires at the beginning and at end of the process. RESULTS: At the end of the process, 33 out of 34 jurors voted in support of the secondary use of data for research, with 24 wanting individuals to be able to opt out, 6 favoring opt in, and 3 voting that all records should be available without any consent process. When considering who should get access to data, both juries had very similar rationales. Both thought that public benefit was a key justification for access. Jury 1 was more strongly supportive of sharing patient records for public benefit, whereas jury 2 was more cautious and sought to give patients more control. Many jurors changed their opinion about who should get access to health records: 17 people became more willing to support wider information sharing of health data for public benefit, whereas 2 moved toward more patient control over patient records. CONCLUSIONS: The findings highlight that, when informed of both risks and opportunities associated with data sharing, citizens believe an individual's right to privacy should not prevent research that can benefit the general public. The juries also concluded that patients should be notified of any such scheme and have the right to opt out if they so choose. Many jurors changed their minds about this complex policy question when they became more informed. Many, but not all, jurors became less skeptical about health data sharing, as they became better informed of its benefits and risks. PMID- 29592848 TI - Consumer Mobile Apps for Potential Drug-Drug Interaction Check: Systematic Review and Content Analysis Using the Mobile App Rating Scale (MARS). AB - BACKGROUND: General consumers can now easily access drug information and quickly check for potential drug-drug interactions (PDDIs) through mobile health (mHealth) apps. With aging population in Canada, more people have chronic diseases and comorbidities leading to increasing numbers of medications. The use of mHealth apps for checking PDDIs can be helpful in ensuring patient safety and empowerment. OBJECTIVE: The aim of this study was to review the characteristics and quality of publicly available mHealth apps that check for PDDIs. METHODS: Apple App Store and Google Play were searched to identify apps with PDDI functionality. The apps' general and feature characteristics were extracted. The Mobile App Rating Scale (MARS) was used to assess the quality. RESULTS: A total of 23 apps were included for the review-12 from Apple App Store and 11 from Google Play. Only 5 of these were paid apps, with an average price of $7.19 CAD. The mean MARS score was 3.23 out of 5 (interquartile range 1.34). The mean MARS scores for the apps from Google Play and Apple App Store were not statistically different (P=.84). The information dimension was associated with the highest score (3.63), whereas the engagement dimension resulted in the lowest score (2.75). The total number of features per app, average rating, and price were significantly associated with the total MARS score. CONCLUSIONS: Some apps provided accurate and comprehensive information about potential adverse drug effects from PDDIs. Given the potentially severe consequences of incorrect drug information, there is a need for oversight to eliminate low quality and potentially harmful apps. Because managing PDDIs is complex in the absence of complete information, secondary features such as medication reminder, refill reminder, medication history tracking, and pill identification could help enhance the effectiveness of PDDI apps.

PMID- 29592849 TI - Online Health Monitoring using Facebook Advertisement Audience Estimates in the United States: Evaluation Study. AB - BACKGROUND: Facebook, the most popular social network with over one billion daily users, provides rich opportunities for its use in the health domain. Though much of Facebook's data are not available to outsiders, the company provides a tool for estimating the audience of Facebook advertisements, which includes aggregated information on the demographics and interests, such as weight loss or dieting, of Facebook users. This paper explores the potential uses of Facebook ad audience estimates for eHealth by studying the following: (1) for what type of health conditions prevalence estimates can be obtained via social media and (2) what type of marker interests are useful in obtaining such estimates, which can then be used for recruitment within online health interventions. OBJECTIVE: The objective of this study was to understand the limitations and capabilities of using Facebook ad audience estimates for public health monitoring and as a recruitment tool for eHealth interventions. METHODS: We use the Facebook Marketing application programming interface to correlate estimated sizes of audiences having health-related interests with public health data. Using several study cases, we identify both potential benefits and challenges in using this tool. RESULTS: We find several limitations in using Facebook ad audience estimates, for example, using placebo interest estimates to control for background level of user activity on the platform. Some Facebook interests such as plus-size clothing show encouraging levels of correlation (r=.74) across the 50 US states; however, we also sometimes find substantial correlations with the placebo interests such as r=.68 between interest in Technology and Obesity prevalence. Furthermore, we find demographic-specific peculiarities in the interests on health-related topics. CONCLUSIONS: Facebook's advertising platform provides aggregate data for more than 190 million US adults. We show how disease specific marker interests can be used to model prevalence rates in a simple and intuitive manner. However, we also illustrate that building effective marker interests involves some trial-and-error, as many details about Facebook's black box remain opaque.

AB - BACKGROUND: Worldwide, many countries have developed a list of essential medicines for children to improve prescribing. We aimed to create an essential medicines list for children in Canada. METHODS: We adapted the previously created preliminary list of essential medicines for adults in Canada and the WHO Model List of Essential Medicines for Children to create a provisional list of essential medicines for children in Canada. Canadian clinicians made suggestions for changes. Literature relevant to each suggestion was presented to clinician scientists, who used a modified nominal group technique to make recommendations on the suggestions. Ontario Public Drug Programs prescription data were reviewed to identify commonly prescribed medications missing from the list. Literature relevant to these medications was shared with a clinician-scientist review panel to determine which should be added, and a revised list was developed. RESULTS: A total of 76 items were removed from the list of essential medicines for adults in Canada because they were not indicated for use in children or were not relevant in the Canadian health care context; 7 medications were added to the child list based on Ontario Public Drugs Programs prescribing data and clinician-scientist review. Suggestions to add, remove or substitute medications were made by peer reviewers and resulted in removal of 1 medication and replacement of 1 medication. The process produced a provisional list of 67 essential medications for children. INTERPRETATION: A provisional list of 67 essential medicines for children was created through a peer-reviewed, multistep process based on current clinical evidence, Canadian clinical practice guidelines and historical prescribing data. It is publicly posted at http://cleanmeds.ca/. The list should be further developed based on wider input and should be continuously revised based on emerging evidence of the safety and effectiveness of these medicines in all pediatric age groups.

PMID- 29592858 TI - Immuno-modulatory effect of local rhEGF treatment during tissue repair in diabetic ulcers. AB - Wound healing is a complex process that can be severely impaired due to pathological situations such as diabetes mellitus. Diabetic foot ulcers are a common complication of this pathology and are characterized by an excessive inflammatory response. In this work, the effects of local treatment with recombinant human epidermal growth factor (rhEGF) were studied using a full thickness wound healing model in streptozotocin-induced diabetic rats. Wound healing process was assessed with different concentrations of rhEGF (0.1, 0.5, 2.0 and 8.0 ug/mL), placebo and both diabetic and non-diabetic controls (n = 53). The macroscopic healing observed in treated diabetic rats was affected by rhEGF concentration. Histologically, we also observed an improvement in the epithelialization, granulation tissue formation and maturation in treated groups, finding again the best response at doses of 0.5 and 2.0 ug/mL. Afterwards, the tissue immune response over time was assessed in diabetic rats using the most effective concentrations of rhEGF (0.5 and 2.0 ug/mL), compared to controls. The presence of macrophages, CD4+ T lymphocytes and CD8+ T lymphocytes, in the reparative tissue was quantified, and cytokine expression was measured by quantitative real-time PCR. rhEGF treatment caused a reduction in the number of infiltrating macrophages in the healing tissue of diabetic, as well as diminished activation of these leukocytes. These findings show that local administration of rhEGF improves the healing process of excisional wounds and the quality of the neoformed tissue in a dose-dependent manner. Besides, this treatment reduces the local inflammation associated with diabetic healing, indicating immuno-modulatory properties.

AB - Cellular senescence is a physiological response by which an organism halts the proliferation of potentially harmful and damaged cells. However, the accumulation of senescent cells over time can become deleterious leading to diseases and physiological decline. Our data reveal a novel interplay between senescence and the stress response that affects both the progression of senescence and the behavior of senescent cells. We show that constitutive exposure to stress induces the formation of stress granules (SGs) in proliferative and presenescent cells, but not in fully senescent cells. Stress granule assembly alone is sufficient to decrease the number of senescent cells without affecting the expression of bona fide senescence markers. SG-mediated inhibition of senescence is associated with the recruitment of the plasminogen activator inhibitor-1 (PAI-1), a known promoter of senescence, to these entities. PAI-1 localization to SGs increases the translocation of cyclin D1 to the nucleus, promotes RB phosphorylation, and maintains a proliferative, non-senescent state. Together, our data indicate that SGs may be targets of intervention to modulate senescence in order to impair or prevent its deleterious effects.

AB - Cadmium in tobacco smoke may contribute to the development of pulmonary emphysema. However, there is poor understanding of the mechanisms behind the pathogenic role of cadmium in this and other smoking-related lung diseases. The traditional focus on the total body burden of cadmium, estimated through analysis of urine, may not fully reflect the local burden of cadmium, since it is inhaled by smokers. Thus, assessing the local accumulation of cadmium in the lungs appears more relevant, given that there is tissue-specific retention of cadmium.In this review, we outline the principal sources of cadmium exposure and the clinical effects of occupational exposure. In addition, we review evidence on local cadmium and its association with alterations in innate immunity in tobacco smokers. Moreover, we scrutinise the data on cadmium as a cause of lung disease in translational models.We conclude that cadmium may contribute to smoking related lung diseases, possibly via an altered redox balance and by making macrophages dysfunctional. However, there is a need for new studies on local cadmium levels and their relation to pathology in long-term tobacco smokers, as well as for more in-depth studies on cellular and molecular mechanisms, to elucidate the importance of cadmium in smoking-related lung diseases. PMID- 29592864 TI - Personalised pulmonary rehabilitation in COPD. AB - This review summarises ongoing developments in personalised medicine and individualised medicine in chronic obstructive pulmonary disease (COPD). Currently applied classification systems largely ignore the complexity and heterogeneity of the COPD syndrome. Personalised medicine has to consider the influence of unique circumstances of the person, which contribute to this heterogeneity and complexity. Pulmonary rehabilitation is described as a comprehensive, individualised intervention based on thorough assessment of identifiable treatable traits. Partnership in care will become a crucial factor to improve and maintain health. Tolerating uncertainty and unpredictability will enrich future doctor-patient relationships.

PMID- 29592867 TI - Periprostatic fat tissue transcriptome reveals a signature diagnostic for high risk prostate cancer. AB - Evidence suggests that altered adipose tissue homeostasis may be an important contributor to the development and/or progression of prostate cancer. In this study, we investigated the adipose transcriptional profiles of low- and high-risk disease to determine both prognostic potential and possible biological drivers of aggressive disease. RNA was extracted from periprostatic adipose tissue from patients categorised as having prostate cancer with either a low or high risk of progression based on tumour characteristics at prostatectomy and profiled by RNA sequencing. The expression of selected genes was then quantified by qRT-PCR in a cross-validation cohort. In the first phase, a total of 677 differentially transcribed genes were identified, from which a subset of 14 genes was shortlisted. In the second phase, a 3 gene (IGHA1, OLFM4, RERGL) signature was refined and evaluated using recursive feature selection and cross-validation, obtaining a promising discriminatory utility (area under curve 0.72) at predicting the presence of high-risk disease. Genes implicated in immune and/or inflammatory responses predominated. Periprostatic adipose tissue from patients with high-risk prostate cancer has a distinct transcriptional signature that may be useful for detecting its occult presence. Differential expression appears to be driven by a local immune/inflammatory reaction to more advanced tumours, than any specific adipose tissue-specific tumour-promoting mechanism. This signature is transferable into a clinically usable PCR-based assay, which in a cross validation cohort shows diagnostic potential. PMID- 29592868 TI - Ki67 proliferative index of the neuroendocrine component drives MANEC prognosis. AB - Mixed adenoneuroendocrine carcinomas (MANECs) are composed of a poorly differentiated neuroendocrine carcinoma (NEC) and a non-neuroendocrine (non-NEC) neoplastic epithelial component, each representing at least 30% of the tumor. At present, prognostic factors for MANECs remain largely unexplored. We investigated the clinical-pathologic features of a large multicenter series of digestive system MANECs. Surgical specimens of 200 MANEC candidates were centrally reviewed; diagnosis was confirmed in 160 cases. While morphology, proliferation (mitotic count (MC), Ki67 index) and immunophenotype (p53, SSTR2a, beta-Catenin, Bcl-2, p16, Rb1, ALDH, mismatch repair proteins and CD117) were investigated separately in both components, genomic (TP53, KRAS, BRAF) alterations were searched for on the entire tumor. Data were correlated with overall survival (OS). MANEC sites were: 92 colorectal, 44 gastroesophageal and 24 pancreatobiliary. Median OS was 13.2 months. After adjustment for primary site, Ki67 index of the NEC component (but not of the non-NEC component) was the most powerful prognostic marker. At multivariable analysis, patients with Ki67 >= 55% had an 8-fold risk of death (hazard ratio (HR) 7.83; 95% confidence interval (CI) 4.17-14.7; P < 0.0001) and a median OS of 12.2 months compared to those with Ki67 < 55% (median OS 40.5 months). MC (HR 1.51; 95% CI 1.03-2.20, P = 0.04) was a weaker prognostic index. Colorectal primary site (HR 1.60; 95% CI 1.11-2.32; P = 0.01) was significantly associated with poorer survival. No single immunomarker, in either component, was statistically significant. This retrospective analysis of a large series of digestive system MANECs, showed that the NEC component, particularly its Ki67 index, was the main prognostic driver.

AB - BACKGROUND: Federal summer meals programs serve less than one-sixth of children that receive free or reduced-price meals during the school year. To address this gap in food assistance for school-aged children, the Summer Electronic Benefits Transfer for Children (SEBTC) Demonstrations provided summer food assistance in the form of electronic benefits transfer cards to households with school-aged children certified for free or reduced-price meals during the school year. METHODS: Over 2011-2013, the SEBTC demonstrations were evaluated by using a random assignment design. Households were randomly assigned a monthly $60-per child benefit, a monthly $30-per-child benefit, or no benefit, depending on the study year. Key outcomes included children's food security and consumption of foods and food groups related to a healthful diet (diet quality). At baseline (in the spring) and again in the summer, the evaluation surveyed ~52 000 households over the course of the 3 years of the impact study. RESULTS: SEBTC reduced the prevalence of very low food security among children by one-third. It also had positive impacts on 6 of the 8 child nutrition outcomes measured (amounts of fruits and vegetables; whole grains; dairy foods; and added sugars). CONCLUSIONS: SEBTC is a promising model to improve food security and the dietary quality of low-income school-aged children in the summer months.

AB - Non-canonical d-amino acids play important roles in bacteria including control of peptidoglycan metabolism and biofilm disassembly. Bacteria appear to produce non canonical d-amino acids to adapt to various environmental changes, and understanding the biosynthetic pathways is important. We identified novel amino acid racemases possessing the ability to produce non-canonical d-amino acids in Escherichia coli and Bacillus subtilis in our previous study, whereas the biosynthetic pathways of these d-amino acids still remain unclear. In the present study, we demonstrated that two cystathionine beta-lyases (MetC and MalY) from E. coli produce non-canonical d-amino acids including non-proteinogenic amino acids. Furthermore, MetC displayed d- and l-serine (Ser) dehydratase activity. We characterised amino acid racemase, Ser dehydratase and cysteine lyase activities, and all were higher for MetC. Interestingly, all three activities were at a comparable level for MetC, although optimal conditions for each reaction were distinct. These results indicate that MetC and MalY are multifunctional enzymes involved in l-methionine metabolism and the production of d-amino acids, as well as d- and l-Ser metabolism. To our knowledge, this is the first evidence that cystathionine beta-lyase is a multifunctional enzyme with three different activities.

AB - Gefitinib resistance is one of the major obstacles for the treatment of lung adenocarcinoma (LAD). The present study aimed to investigate the effects of the long non-coding RNA (lncRNA), small nucleolar RNA host gene 5SNHG5 on gefitinib resistance in LAD and explore the underlying mechanisms. The quantitative real time PCR (qRT-PCR) results showed that SNHG5 expression was significantly down regulated in LAD patients with acquired gefitinib resistance and gefitinib resistant LAD cell lines. SNHG5 overexpression sensitized gefitinib resistant LAD cells to gefitinib treatment, while knockdown of SNHG5 rendered gefitinib sensitive LAD cells to gefitinib treatment. Bioinformatics analysis showed that SNHG5 exerted its function through interaction with miR-377, which was further confirmed by luciferase reporter assay in 293T cells. Overexpression of SNHG5 suppressed the expression of miR-377, while the knockdown of SNHG5 increased the miR-377 expression. MiR-377 expression was significantly up-regulated in LAD specimens with acquired gefitinib resistance and was negatively correlated with SNHG5 expression. In addition, CASP1 was predicted as a downstream target of miR 377 Overexpression of miR-377 suppressed the expression of CASP1 in PC9 cells and knockdown of miR-377 increased the CASP1 expression in PC9GR cells. In vitro functional assay showed that knockdown of CASP1 in SNHG5-overexpressed PC9GR cells abolished their gefitinib resistance. Overall, the present study demonstrated, for the first time, that the SNHG5/miR-377/CASP1 axis functions as an important role in LAD cells gefitinib resistance and potentially contributes to the improvement of LAD diagnosis and therapy. PMID- 29592873 TI - Atorvastatin ameliorates early brain injury through inhibition of apoptosis and ER stress in a rat model of subarachnoid hemorrhage. AB - Aneurysmal subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease with very poor prognosis. The aim of the present study was to evaluate the protective effects of atorvastatin on early brain injury (EBI) after SAH using a perforation SAH model. Male Sprague-Dawley rats were randomly divided into four groups: the sham group, the SAH group (model group), SAH + 10 mg.kg-1day-1 atorvastatin (low atorvastatin group), and SAH + 20 mg.kg-1day-1 atorvastatin (high atorvastatin group). Atorvastatin was administered orally by gastric gavage for 15 days before operation. At 24 h after SAH, we evaluated the effects of atorvastatin on brain water content, apoptosis by TUNEL assay and scanning electron microscope (SEM), and the expression of apoptosis-related proteins by immunofluorescence and Western blotting analysis. Compared with the sham group, we observed increased brain water content, significant apoptosis, and elevated levels of apoptosis related proteins including caspase-3, CCAAT enhancer-binding protein homologous protein (CHOP), the 78-kDa glucose-regulated protein (GRP78), and aquaporin-4 (AQP4) in the SAH group. Atorvastatin administration under all doses could significantly reduce brain water content, apoptosis, and the expression levels of caspase-3, CHOP, GRP78, and AQP4 at 24 h after SAH. Our data show that early treatment with atorvastatin effectively ameliorates EBI after SAH through anti apoptotic effects and the effects might be associated inhibition of caspase-3 and endoplasmic reticulum (ER) stress related proteins CHOP and GRP78. PMID- 29592875 TI - Selectins and chemokines use shared and distinct signals to activate beta2 integrins in neutrophils. AB - Rolling neutrophils receive signals while engaging P- and E-selectin and chemokines on inflamed endothelium. Selectin signaling activates beta2 integrins to slow rolling velocities. Chemokine signaling activates beta2 integrins to cause arrest. Despite extensive study, key aspects of these signaling cascades remain unresolved. Using complementary in vitro and in vivo assays, we found that selectin and chemokine signals in neutrophils triggered Rap1a-dependent and phosphatidylinositol-4-phosphate 5-kinase gamma (PIP5Kgamma90)-dependent pathways that induce integrin-dependent slow rolling and arrest. Interruption of both pathways, but not either pathway alone, blocked talin-1 recruitment to and activation of integrins. An isoform of PIP5Kgamma90 lacking the talin-binding domain (PIP5Kgamma87) could not activate integrins. Chemokines, but not selectins, used phosphatidylinositol-4,5-bisphosphate 3-kinase gamma (PI3Kgamma) in cooperation with Rap1a to mediate integrin-dependent slow rolling (at low chemokine concentrations), as well as arrest (at high chemokine concentrations). High levels of chemokines activated beta2 integrins without selectin signals. When chemokines were limiting, they synergized with selectins to activate beta2 integrins. PMID- 29592874 TI - Decreased A-to-I RNA editing as a source of keratinocytes' dsRNA in psoriasis. AB - Recognition of dsRNA molecules activates the MDA5-MAVS pathway and plays a critical role in stimulating type-I interferon responses in psoriasis. However, the source of the dsRNA accumulation in psoriatic keratinocytes remains largely unknown. A-to-I RNA editing is a common co- or post-transcriptional modification that diversifies adenosine in dsRNA, and leads to unwinding of dsRNA structures. Thus, impaired RNA editing activity can result in an increased load of endogenous dsRNAs. Here we provide a transcriptome-wide analysis of RNA editing across dozens of psoriasis patients, and we demonstrate a global editing reduction in psoriatic lesions. In addition to the global alteration, we also detect editing changes in functional recoding sites located in the IGFBP7, COPA, and FLNA genes. Accretion of dsRNA activates autoimmune responses, and therefore the results presented here, linking for the first time an autoimmune disease to reduction in global editing level, are relevant to a wide range of autoimmune diseases. PMID- 29592876 TI - Third-party fecal microbiota transplantation following allo-HCT reconstitutes microbiome diversity. AB - We hypothesized that third-party fecal microbiota transplantation (FMT) may restore intestinal microbiome diversity after allogeneic hematopoietic cell transplantation (allo-HCT). In this open-label single-group pilot study, 18 subjects were enrolled before allo-HCT and planned to receive third-party FMT capsules. FMT capsules were administered no later than 4 weeks after neutrophil engraftment, and antibiotics were not allowed within 48 hours before FMT. Five patients did not receive FMT because of the development of early acute gastrointestinal (GI) graft-versus-host disease (GVHD) before FMT (n = 3), persistent HCT-associated GI toxicity (n = 1), or patient decision (n = 1). Thirteen patients received FMT at a median of 27 days (range, 19-45 days) after HCT. Participants were able to swallow and tolerate all FMT capsules, meeting the primary study endpoint of feasibility. FMT was tolerated well, with 1 treatment related significant adverse event (abdominal pain). Two patients subsequently developed acute GI GVHD, with 1 patient also having concurrent bacteremia. No additional cases of bacteremia occurred. Median follow-up for survivors is 15 months (range, 13-20 months). The Kaplan-Meier estimates for 12-month overall survival and progression-free survival after FMT were 85% (95% confidence interval, 51%-96%) and 85% (95% confidence interval, 51%-96%), respectively. There was 1 nonrelapse death resulting from acute GI GVHD (12-month nonrelapse mortality, 8%; 95% confidence interval, 0%-30%). Analysis of stool composition and urine 3-indoxyl sulfate concentration indicated improvement in intestinal microbiome diversity after FMT that was associated with expansion of stool-donor taxa. These results indicate that empiric third-party FMT after allo-HCT appears to be feasible, safe, and associated with expansion of recipient microbiome diversity. This trial was registered at www.clinicaltrials.gov as #NCT02733744. PMID- 29592877 TI - Analysis of HSP27 and the Autophagy Marker LC3B+ Puncta Following Preoperative Chemotherapy Identifies High-Risk Osteosarcoma Patients. AB - Chemotherapy-induced autophagy is a proposed mechanism of chemoresistance and potential therapeutic target in osteosarcoma. We evaluated heat shock protein 27 (HSP27) and autophagy-related proteins as predictors of pathologic treatment response and prognostic markers among osteosarcoma patients who received standard chemotherapy. We analyzed 394 tumor specimens (pre-treatment, post-treatment, and metastases) from 260 osteosarcoma patients by immunohistochemistry for cytoplasmic light chain 3B (LC3B)-positive puncta, sequestosome 1 (SQSTM1), high mobility group box 1 (HMGB1), and HSP27 expression. The staining percentage and intensity for each marker were scored and the extent to which marker expression was correlated with pathologic response, relapse-free survival (RFS), and overall survival (OS) was assessed. LCB3+ puncta in post-treatment primary tumors (50%) and metastases (67%) was significantly higher than in pre-treatment biopsy specimens (30%; P = 0.023 and <0.001). Among 215 patients with localized osteosarcoma, both pre-treatment [multivariate hazard ratio (HR), 26.7; 95% confidence interval (CI), 1.47-484; P = 0.026] and post-treatment HSP27 expression (multivariate HR, 1.85; 95% CI, 1.03-3.33; P = 0.039) were associated with worse OS. Lack of LC3B+ puncta at resection was an independent poor prognostic marker in both univariate (HR, 1.78; 95% CI, 1.05-3.03; P = 0.034) and multivariate models (HR, 1.75; 95% CI, 1.01-3.04; P = 0.045). Patients with LC3B+/HSP27- tumors at resection had the best 10-year OS (75%) whereas patients with LC3B-/HSP27+ tumors had the worst 10-year survival (25%). Neither HSP27 expression nor the presence of LCB3+ puncta was correlated with pathologic treatment response. Our findings establish HSP27 expression and LC3B+ puncta as independent prognostic markers in osteosarcoma patients receiving standard chemotherapy and support further investigation into strategies targeting HSP27 or modulating autophagy in osteosarcoma treatment.

AB - We investigated the role of NF-kappaB in the development and progression of urothelial cancer as well as cross-talk between NF-kappaB and androgen receptor (AR) signals in urothelial cells. Immunohistochemistry in surgical specimens showed that the expression levels of NF-kappaB/p65 (P = 0.015)/phospho-NF kappaB/p65 (P < 0.001) were significantly elevated in bladder tumors, compared with those in nonneoplastic urothelial tissues. The rates of phospho-NF kappaB/p65 positivity were also significantly higher in high-grade (P = 0.015)/muscle-invasive (P = 0.033) tumors than in lower grade/non-muscle-invasive tumors. Additionally, patients with phospho-NF-kappaB/p65-positive muscle invasive bladder cancer had significantly higher risks of disease progression (P < 0.001) and cancer-specific mortality (P = 0.002). In immortalized human normal urothelial SVHUC cells stably expressing AR, NF-kappaB activators and inhibitors accelerated and prevented, respectively, their neoplastic transformation induced by a chemical carcinogen 3-methylcholanthrene. Bladder tumors were identified in 56% (mock), 89% (betulinic acid), and 22% (parthenolide) of N-butyl-N-(4 hydroxybutyl)nitrosamine-treated male C57BL/6 mice at 22 weeks of age. NF-kappaB activators and inhibitors also significantly induced and reduced, respectively, cell proliferation/migration/invasion of AR-positive bladder cancer lines, but not AR-knockdown or AR-negative lines, and their growth in xenograft-bearing mice. In both nonneoplastic and neoplastic urothelial cells, NF-kappaB activators/inhibitors upregulated/downregulated, respectively, AR expression, whereas AR overexpression was associated with increases in the expression levels of NF-kappaB/p65 and phospho-NF-kappaB/p65. Thus, NF-kappaB appeared to be activated in bladder cancer, which was associated with tumor progression. NF kappaB activators/inhibitors were also found to modulate tumorigenesis and tumor outgrowth in AR-activated urothelial cells. Accordingly, NF-kappaB inhibition, together with AR inactivation, has the potential of being an effective chemopreventive and/or therapeutic approach for urothelial carcinoma.

AB - We here evaluated the antiesophageal cancer cell activity by the antifungal drug itraconazole. Our results show that MUg/mL concentrations of itraconazole potently inhibited survival and proliferation of established (TE-1 and Eca-109) and primary human esophageal cancer cells. Itraconazole activated AMPK signaling, which was required for subsequent esophageal cancer cell death. Pharmacologic AMPK inhibition, AMPKalpha1 shRNA, or dominant negative mutation (T172A) almost completely abolished itraconazole-induced cytotoxicity against esophageal cancer cells. Significantly, itraconazole induced AMPK-dependent autophagic cell death (but not apoptosis) in esophageal cancer cells. Furthermore, AMPK activation by itraconazole induced multiple receptor tyrosine kinases (RTKs: EGFR, PDGFRalpha, and PDGFRbeta), lysosomal translocation, and degradation to inhibit downstream Akt activation. In vivo, itraconazole oral gavage potently inhibited Eca-109 tumor growth in SCID mice. It was yet ineffective against AMPKalpha1 shRNA expressing Eca-109 tumors. The in vivo growth of the primary human esophageal cancer cells was also significantly inhibited by itraconazole administration. AMPK activation, RTK degradation, and Akt inhibition were observed in itraconazole-treated tumors. Together, itraconazole inhibits esophageal cancer cell growth via activating AMPK signaling.

AB - HER2-targeted therapies, such as trastuzumab, have increased the survival rates of HER2+ breast cancer patients. However, despite these therapies, many tumors eventually develop resistance to these therapies. Our lab previously reported an unexpected sensitivity of HER2+ breast cancer cells to poly (ADP-ribose) polymerase inhibitors (PARPi), agents that target homologous recombination (HR) deficient tumors, independent of a DNA repair deficiency. In this study, we investigated whether HER2+ trastuzumab-resistant (TR) breast cancer cells were susceptible to PARPi and the mechanism behind PARPi induced cytotoxicity. We demonstrate that the PARPi ABT-888 (veliparib) decreased cell survival in vitro and tumor growth in vivo of HER2+ TR breast cancer cells. PARP-1 siRNA confirmed that cytotoxicity was due, in part, to PARP-1 inhibition. Furthermore, PARP-1 silencing had variable effects on the expression of several NF-kappaB-regulated genes. In particular, silencing PARP-1 inhibited NF-kappaB activity and reduced p65 binding at the IL8 promoter, which resulted in a decrease in IL8 mRNA and protein expression. Our results provide insight in the potential mechanism by which PARPi induces cytotoxicity in HER2+ breast cancer cells and support the testing of PARPi in patients with HER2+ breast cancer resistant to trastuzumab.

AB - Tumor-targeted drug delivery has the potential to improve therapeutic efficacy and mitigate non-specific toxicity of anticancer drugs. However, current drug delivery approaches rely on inefficient passive accumulation of the drug carrier in the tumor. We have developed a unique, truly active tumor-targeting strategy that relies on engineering mesenchymal stem cells (MSC) with drug-loaded nanoparticles. Our studies using the A549 orthotopic lung tumor model show that nano-engineered MSCs carrying the anticancer drug paclitaxel (PTX) home to tumors and create cellular drug depots that release the drug payload over several days. Despite significantly lower doses of PTX, nano-engineered MSCs resulted in significant inhibition of tumor growth and superior survival. Anticancer efficacy of nano-engineered MSCs was confirmed in immunocompetent C57BL/6 albino female mice bearing orthotopic Lewis Lung Carcinoma (LL/2-luc) tumors. Furthermore, at doses that resulted in equivalent therapeutic efficacy, nano-engineered MSCs had no effect on white blood cell count, whereas PTX solution and PTX nanoparticle treatments caused leukopenia. Biodistribution studies showed that nano-engineered MSCs resulted in greater than 9-fold higher AUClung of PTX (1.5 MUg.day/g) than PTX solution and nanoparticles (0.2 and 0.1 MUg.day/g tissue, respectively) in the target lung tumors. Furthermore, the lung-to-liver and the lung-to-spleen ratios of PTX were several folds higher for nano-engineered MSCs relative to those for PTX solution and nanoparticle groups, suggesting that nano-engineered MSCs demonstrate significantly less off-target deposition. In summary, our results demonstrate that nano-engineered MSCs can serve as an efficient carrier for tumor-specific drug delivery and significantly improved anti-cancer efficacy of conventional chemotherapeutic drugs.

PMID- 29592882 TI - ABT-165, a Dual Variable Domain Immunoglobulin (DVD-Ig) Targeting DLL4 and VEGF, Demonstrates Superior Efficacy and Favorable Safety Profiles in Preclinical Models. AB - Antiangiogenic therapy is a clinically validated modality in cancer treatment. To date, all approved antiangiogenic drugs primarily inhibit the VEGF pathway. Delta like ligand 4 (DLL4) has been identified as a potential drug target in VEGF independent angiogenesis and tumor-initiating cell (TIC) survival. A dual specific biologic targeting both VEGF and DLL4 could be an attractive strategy to improve the effectiveness of anti-VEGF therapy. ABT-165 was uniquely engineered using a proprietary dual-variable domain immunoglobulin (DVD-Ig) technology based on its ability to bind and inhibit both DLL4 and VEGF. In vivo, ABT-165 induced significant tumor growth inhibition compared with either parental antibody treatment alone, due, in part, to the disruption of functional tumor vasculature. In combination with chemotherapy agents, ABT-165 also induced greater antitumor response and outperformed anti-VEGF treatment. ABT-165 displayed nonlinear pharmacokinetic profiles in cynomolgus monkeys, with an apparent terminal half life > 5 days at a target saturation dose. In a GLP monkey toxicity study, ABT 165 was well-tolerated at doses up to 200 mg/kg with non-adverse treatment related histopathology findings limited to the liver and thymus. In summary, ABT 165 represents a novel antiangiogenic strategy that potently inhibits both DLL4 and VEGF, demonstrating favorable in vivo efficacy, pharmacokinetic, and safety profiles in preclinical models. Given these preclinical attributes, ABT-165 has progressed to a phase I study. Mol Cancer Ther; 17(5); 1039-50. (c)2018 AACR. PMID- 29592884 TI - Mechanistic Modeling of Antibody-Drug Conjugate Internalization at the Cellular Level Reveals Inefficient Processing Steps. AB - Antibody-drug conjugates (ADC) offer an avenue for specific drug delivery to target cells. Here, parameters with important roles in the cellular processing of ADCs were quantitatively measured for Ab033, an antibody against EGFR. In EGFR overexpressing cancer cell lines, Ab033 internalized at rates of 0.047/min and 0.15/min for A431 and H441 cells, respectively. Once internalized, Ab033 either trafficked to the lysosome or was recycled; up to 45% of internalized Ab033 returned to the cell surface. Despite such recycling, intracellular accumulation of Ab033 continually increased over 24 hours. Ab033 was conjugated to form a dual toxin ADC containing both cleavable and non-cleavable linker-drug payloads for release rate comparisons. Intracellular concentrations of freed drug from cleavable linker were greater than from non-cleavable linker and exceeded 5 * 106 drug molecules per A431 cell after 24 hours. Compared with intracellular antibody accumulation, formation of released drug was delayed, likely due to the time needed for endo-lysosomal trafficking and subsequent linker/antibody proteolysis. Informed by the quantitative data, a cellular ADC model was constructed and used to summarize processing inefficiencies. Modeling simulations were conducted to determine parameter sensitivity on intracellular drug concentrations, with rates of EGFR internalization and recycling as well as ADC trafficking found to be the most sensitive toward final intracellular drug concentrations. Overall, this study shows Ab033 ADCs to be a viable strategy for delivery of cytotoxic drugs into tumor cells with subsequent modeling efforts able to highlight key processing steps to be improved for increased drug delivery.

PMID- 29592883 TI - Gallium Maltolate Disrupts Tumor Iron Metabolism and Retards the Growth of Glioblastoma by Inhibiting Mitochondrial Function and Ribonucleotide Reductase. AB - Gallium, a metal with antineoplastic activity, binds transferrin (Tf) and enters tumor cells via Tf receptor1 (TfR1); it disrupts iron homeostasis leading to cell death. We hypothesized that TfR1 on brain microvascular endothelial cells (BMEC) would facilitate Tf-Ga transport into the brain enabling it to target TfR-bearing glioblastoma. We show that U-87 MG and D54 glioblastoma cell lines and multiple glioblastoma stem cell (GSC) lines express TfRs, and that their growth is inhibited by gallium maltolate (GaM) in vitro After 24 hours of incubation with GaM, cells displayed a loss of mitochondrial reserve capacity followed by a dose dependent decrease in oxygen consumption and a decrease in the activity of the iron-dependent M2 subunit of ribonucleotide reductase (RRM2). IHC staining of rat and human tumor-bearing brains showed that glioblastoma, but not normal glial cells, expressed TfR1 and RRM2, and that glioblastoma expressed greater levels of H- and L-ferritin than normal brain. In an orthotopic U-87 MG glioblastoma xenograft rat model, GaM retarded the growth of brain tumors relative to untreated control (P = 0.0159) and reduced tumor mitotic figures (P = 0.045). Tumors in GaM-treated animals displayed an upregulation of TfR1 expression relative to control animals, thus indicating that gallium produced tumor iron deprivation. GaM also inhibited iron uptake and upregulated TfR1 expression in U 87 MG and D54 cells in vitro We conclude that GaM enters the brain via TfR1 on BMECs and targets iron metabolism in glioblastoma in vivo, thus inhibiting tumor growth. Further development of novel gallium compounds for brain tumor treatment is warranted. Mol Cancer Ther; 17(6); 1240-50. (c)2018 AACR. PMID- 29592885 TI - Resistance vs resilience to Alzheimer disease: Clarifying terminology for preclinical studies. AB - Preventing or delaying Alzheimer disease (AD) through lifestyle interventions will come from a better understanding of the mechanistic underpinnings of (1) why a significant proportion of elderly remain cognitively normal with AD pathologies (ADP), i.e., amyloid or tau; and (2) why some elderly individuals do not have significant ADP. In the last decades, concepts such as brain reserve, cognitive reserve, and more recently brain maintenance have been proposed along with more general notions such as (neuro)protection and compensation. It is currently unclear how to effectively apply these concepts in the new field of preclinical AD specifically separating the 2 distinct mechanisms of coping with pathology vs avoiding pathology. We propose a simplistic conceptual framework that builds on existing concepts using the nomenclature of resistance in the context of avoiding pathology, i.e., remaining cognitively normal without significant ADP, and resilience in the context of coping with pathology, i.e., remaining cognitively normal despite significant ADP. In the context of preclinical AD studies, we (1) define these concepts and provide recommendations (and common scenarios) for their use; (2) discuss how to employ this terminology in the context of investigating mechanisms and factors; (3) highlight the complementarity and clarity they provide to existing concepts; and (4) discuss different study designs and methodologies. The application of the proposed framework for framing hypotheses, study design, and interpretation of results and mechanisms can provide a consistent framework and nomenclature for researchers to reach consensus on identifying factors that may prevent ADP or delay the onset of cognitive impairment. PMID- 29592886 TI - The most affected health domains after ischemic stroke. AB - OBJECTIVES: (1) Examine 8 patient-reported domains of health across levels of disability compared to the US general population; and (2) identify factors associated with domain scores in patients with ischemic stroke. METHODS: Observational cohort study of 1,195 patients in a cerebrovascular clinic from February 17, 2015, to January 27, 2017, who completed Neuro-QoL (Quality of Life in Neurological Disorders) executive function or the following PROMIS (Patient Reported Outcomes Measurement Information System) scales as part of routine care: physical function, satisfaction with social roles, fatigue, anxiety, depression, pain interference, and sleep disturbance. RESULTS: Mean age was 62 (+/-15) years, and 81% were white. Median modified Rankin Scale (mRS) score at the clinic visit was 1 (interquartile range 0-2). Percentage of patients with scores meaningfully worse than the general population ranged from 28% (sleep disturbance) to 63% (physical function). Scores were worse in patients with higher mRS levels, although correlation between scores and mRS level varied (sleep disturbance r = 0.16 to physical function r = 0.52). Most affected domains were physical function (T score = 58.8), satisfaction with social roles (T score = 55.4), and executive function (T score = 53.4). Disability, lower income, and female sex were associated with worse scores in multiple domains. Age was associated with worse physical function but lower anxiety, depression, and sleep disturbance. CONCLUSIONS: Patients with ischemic stroke reported symptoms in multiple domains that increase to variable degrees at higher levels of disability. Physical function, satisfaction with social roles, and executive function were most affected. This information improves our understanding of the well-being of patients with ischemic stroke and brings attention to the importance of social roles and executive function for stroke survivors. PMID- 29592887 TI - Patient-reported outcomes after ischemic stroke as part of routine care. PMID- 29592888 TI - Dorsal and ventral horn atrophy is associated with clinical outcome after spinal cord injury. AB - OBJECTIVE: To investigate whether gray matter pathology above the level of injury, alongside white matter changes, also contributes to sensorimotor impairments after spinal cord injury. METHODS: A 3T MRI protocol was acquired in 17 tetraplegic patients and 21 controls. A sagittal T2-weighted sequence was used to characterize lesion severity. At the C2-3 level, a high-resolution T2* weighted sequence was used to assess cross-sectional areas of gray and white matter, including their subcompartments; a diffusion-weighted sequence was used to compute voxel-based diffusion indices. Regression models determined associations between lesion severity and tissue-specific neurodegeneration and associations between the latter with neurophysiologic and clinical outcome. RESULTS: Neurodegeneration was evident within the dorsal and ventral horns and white matter above the level of injury. Tract-specific neurodegeneration was associated with prolonged conduction of appropriate electrophysiologic recordings. Dorsal horn atrophy was associated with sensory outcome, while ventral horn atrophy was associated with motor outcome. White matter integrity of dorsal columns and corticospinal tracts was associated with daily-life independence. CONCLUSION: Our results suggest that, next to anterograde and retrograde degeneration of white matter tracts, neuronal circuits within the spinal cord far above the level of injury undergo transsynaptic neurodegeneration, resulting in specific gray matter changes. Such improved understanding of tissue-specific cord pathology offers potential biomarkers with more efficient targeting and monitoring of neuroregenerative (i.e., white matter) and neuroprotective (i.e., gray matter) agents. PMID- 29592889 TI - Dissociable influences of APOE epsilon4 and polygenic risk of AD dementia on amyloid and cognition. AB - OBJECTIVE: To investigate the effects of genetic risk of Alzheimer disease (AD) dementia in the context of beta-amyloid (Abeta) accumulation. METHODS: We analyzed data from 702 participants (221 clinically normal, 367 with mild cognitive impairment, and 114 with AD dementia) with genetic data and florbetapir PET available. A subset of 669 participants additionally had longitudinal MRI scans to assess hippocampal volume. Polygenic risk scores (PRSs) were estimated with summary statistics from previous large-scale genome-wide association studies of AD dementia. We examined relationships between APOE epsilon4 status and PRS with longitudinal Abeta and cognitive and hippocampal volume measurements. RESULTS: APOE epsilon4 was strongly related to baseline Abeta, whereas only weak associations between PRS and baseline Abeta were present. APOE epsilon4 was additionally related to greater memory decline and hippocampal atrophy in Abeta+ participants. When APOE epsilon4 was controlled for, PRS was related to cognitive decline in Abeta+ participants. Finally, PRSs were associated with hippocampal atrophy in Abeta- participants and weakly associated with baseline hippocampal volume in Abeta+ participants. CONCLUSIONS: Genetic risk factors of AD dementia demonstrate effects related to Abeta, as well as synergistic interactions with Abeta. The specific effect of faster cognitive decline in Abeta+ individuals with higher genetic risk may explain the large degree of heterogeneity in cognitive trajectories among Abeta+ individuals. Consideration of genetic variants in conjunction with baseline Abeta may improve enrichment strategies for clinical trials targeting Abeta+ individuals most at risk for imminent cognitive decline.

AB - The nature of host organs and genes that underlie tumor-induced physiological disruption on the host remains ill-defined. Here, we establish a novel zebrafish intestinal tumor model that is suitable for addressing this issue, and find that hepatic cyp7a1, the rate-limiting factor for synthesizing bile acids [or, in the case of zebrafish, bile alcohol (BA)], is such a host gene. Inducing krasG12D by Gal4 specifically expressed in the posterior intestine resulted in the formation of an intestinal tumor. The local intestinal tumor caused systemic detrimental effects on the host, including liver inflammation, hepatomegaly, growth defects and organismal death. Whole-organism-level gene expression analysis and metabolite measurements revealed that the intestinal tumor reduced total BA levels, possibly via altered expression of hepatic cyp7a1 Genetically overexpressing cyp7a1 in the liver restored BA synthesis and ameliorated tumor induced liver inflammation, but not other tumor-dependent phenotypes. Thus, we found a previously unknown role of cyp7a1 as the host gene that links the intestinal tumor, hepatic cholesterol-BA metabolism and liver inflammation in tumor-bearing zebrafish larvae. Our model provides an important basis to discover host genes responsible for tumor-induced phenotypes and to uncover mechanisms underlying how tumors adversely affect host organisms. PMID- 29592891 TI - Warfarin alters vitamin K metabolism: a surprising mechanism of VKORC1 uncoupling necessitates an additional reductase. AB - The anticoagulant warfarin inhibits the vitamin K oxidoreductase (VKORC1), which generates vitamin K hydroquinone (KH2) required for the carboxylation and consequent activation of vitamin K-dependent (VKD) proteins. VKORC1 produces KH2 in 2 reactions: reduction of vitamin K epoxide (KO) to quinone (K), and then KH2 Our dissection of full reduction vs the individual reactions revealed a surprising mechanism of warfarin inhibition. Warfarin inhibition of KO to K reduction and carboxylation that requires full reduction were compared in wild type VKORC1 or mutants (Y139H, Y139F) that cause warfarin resistance. Carboxylation was much more strongly inhibited (~400-fold) than KO reduction (two to threefold). The K to KH2 reaction was analyzed using low K concentrations that result from inhibition of KO to K. Carboxylation that required only K to KH2 reduction was inhibited much less than observed with the KO substrate that requires full VKORC1 reduction (eg, 2.5-fold vs 70-fold, respectively, in cells expressing wild-type VKORC1 and factor IX). The results indicate that warfarin uncouples the 2 reactions that fully reduce KO. Uncoupling was revealed because a second activity, a warfarin-resistant quinone reductase, was not present. In contrast, 293 cells expressing factor IX and this reductase activity showed much less inhibition of carboxylation. This activity therefore appears to cooperate with VKORC1 to accomplish full KO reduction. Cooperation during warfarin therapy would have significant consequences, as VKD proteins function in numerous physiologies in many tissues, but may be poorly carboxylated and dysfunctional if the second activity is not ubiquitously expressed similar to VKORC1. PMID- 29592892 TI - Gene dosage effect of CUX1 in a murine model disrupts HSC homeostasis and controls the severity and mortality of MDS. AB - Monosomy 7 (-7) and del(7q) are high-risk cytogenetic abnormalities common in myeloid malignancies. We previously reported that CUX1, a homeodomain-containing transcription factor encoded on 7q22, is frequently inactivated in myeloid neoplasms, and CUX1 myeloid tumor suppressor activity is conserved from humans to Drosophila. CUX1-inactivating mutations are recurrent in clonal hematopoiesis of indeterminate potential as well as myeloid malignancies, in which they independently carry a poor prognosis. To determine the role for CUX1 in hematopoiesis, we generated 2 short hairpin RNA-based mouse models with ~54% (Cux1mid) or ~12% (Cux1low) residual CUX1 protein. Cux1mid mice develop myelodysplastic syndrome (MDS) with anemia and trilineage dysplasia, whereas CUX1low mice developed MDS/myeloproliferative neoplasms and anemia. In diseased mice, restoration of CUX1 expression was sufficient to reverse the disease. CUX1 knockdown bone marrow transplant recipients exhibited a transient hematopoietic expansion, followed by a reduction of hematopoietic stem cells (HSCs), and fatal bone marrow failure, in a dose-dependent manner. RNA-sequencing after CUX1 knockdown in human CD34+ cells identified a -7/del(7q) MDS gene signature and altered differentiation, proliferative, and phosphatidylinositol 3-kinase (PI3K) signaling pathways. In functional assays, CUX1 maintained HSC quiescence and repressed proliferation. These homeostatic changes occurred in parallel with decreased expression of the PI3K inhibitor, Pik3ip1, and elevated PI3K/AKT signaling upon CUX1 knockdown. Our data support a model wherein CUX1 knockdown promotes PI3K signaling, drives HSC exit from quiescence and proliferation, and results in HSC exhaustion. Our results also demonstrate that reduction of a single 7q gene, Cux1, is sufficient to cause MDS in mice.

PMID- 29592894 TI - Daunorubicin reduces MBNL1 sequestration caused by CUG-repeat expansion and rescues cardiac dysfunctions in a Drosophila model of myotonic dystrophy. AB - Myotonic dystrophy (DM) is a dominantly inherited neuromuscular disorder caused by expression of mutant myotonin-protein kinase (DMPK) transcripts containing expanded CUG repeats. Pathogenic DMPK RNA sequesters the muscleblind-like (MBNL) proteins, causing alterations in metabolism of various RNAs. Cardiac dysfunction represents the second most common cause of death in DM type 1 (DM1) patients. However, the contribution of MBNL sequestration in DM1 cardiac dysfunction is unclear. We overexpressed Muscleblind (Mbl), the DrosophilaMBNL orthologue, in cardiomyocytes of DM1 model flies and observed a rescue of heart dysfunctions, which are characteristic of these model flies and resemble cardiac defects observed in patients. We also identified a drug - daunorubicin hydrochloride - that directly binds to CUG repeats and alleviates Mbl sequestration in Drosophila DM1 cardiomyocytes, resulting in mis-splicing rescue and cardiac function recovery. These results demonstrate the relevance of Mbl sequestration caused by expanded-CUG-repeat RNA in cardiac dysfunctions in DM1, and highlight the potential of strategies aimed at inhibiting this protein-RNA interaction to recover normal cardiac function. PMID- 29592896 TI - Harnessing and Optimizing the Interplay between Immunotherapy and Radiotherapy to Improve Survival Outcomes. AB - In the past, radiotherapy was primarily used to control local disease, but recent technological advances in accurate, high-dose ionizing radiation (IR) delivery have not only increased local tumor control but in some cases reduced metastatic burden. These "off target" therapeutic effects of IR at nonirradiated tumor sites, also known as abscopal effects, are thought to be mediated by tumor antigen-primed T cells that travel to metastatic sites and promote tumor regression. Similarly, early indications reveal that IR in combination with immune checkpoint inhibitors, such as ipilimumab (anti-CTLA-4) and nivolumab (anti-PD-1), can provide superior therapeutic responses. These observations suggest that local radiotherapy results in altered gene expression, exposure of new antigens, or cell death that can interact with immunotherapy. As such, radiotherapy enhancement of immune responses offers a promising synergy with the potential for substantial clinical benefit. This review focuses on the biology that underlies the mechanisms for the interaction between radiation-induced tumor cell death and enhanced immunologic response. Mol Cancer Res; 16(8); 1209-14. (c)2018 AACR. PMID- 29592895 TI - Kinetic Modeling of Virus Growth in Cells. AB - When a virus infects a host cell, it hijacks the biosynthetic capacity of the cell to produce virus progeny, a process that may take less than an hour or more than a week. The overall time required for a virus to reproduce depends collectively on the rates of multiple steps in the infection process, including initial binding of the virus particle to the surface of the cell, virus internalization and release of the viral genome within the cell, decoding of the genome to make viral proteins, replication of the genome, assembly of progeny virus particles, and release of these particles into the extracellular environment. For a large number of virus types, much has been learned about the molecular mechanisms and rates of the various steps. However, in only relatively few cases during the last 50 years has an attempt been made-using mathematical modeling-to account for how the different steps contribute to the overall timing and productivity of the infection cycle in a cell. Here we review the initial case studies, which include studies of the one-step growth behavior of viruses that infect bacteria (Qbeta, T7, and M13), human immunodeficiency virus, influenza A virus, poliovirus, vesicular stomatitis virus, baculovirus, hepatitis B and C viruses, and herpes simplex virus. Further, we consider how such models enable one to explore how cellular resources are utilized and how antiviral strategies might be designed to resist escape. Finally, we highlight challenges and opportunities at the frontiers of cell-level modeling of virus infections. PMID- 29592897 TI - Ferroptosis-Induced Endoplasmic Reticulum Stress: Cross-talk between Ferroptosis and Apoptosis. AB - Since its discovery in 2012, ferroptosis has been well characterized by the accumulation of lipid peroxides due to the failure of glutathione-dependent antioxidant defenses. It is known as an iron-dependent form of programmed cell death, which is distinct from other forms of cell death such as apoptosis and necrosis. Nonetheless, little is known about the ferroptotic agent-induced endoplasmic reticulum (ER) stress response and its role in cell death. Recent studies reveal that the ferroptotic agent-induced ER stress response plays an important role in the cross-talk between ferroptosis and other types of cell death. Ferroptotic agents induce the unfolded protein response and subsequently ER stress-mediated activation of the PERK-eIF2alpha-ATF4-CHOP pathway. CHOP (C/EBP homologous protein) signaling pathway-mediated p53-independent PUMA (p53 upregulated modulator of apoptosis) expression is involved in the synergistic interaction between ferroptosis and apoptosis. This review highlights the recent literature on ferroptotic and apoptotic agent interactions through the ER stress mediated PERK-eIF2alpha-ATF4-CHOP-PUMA pathway and implicates combined treatment to effectively enhance tumoricidal efficacy as a novel therapeutic strategy for cancer.

AB - In multiple myeloma, abnormal plasma cells accumulate and proliferate in the bone marrow. Recently, we observed that Runx2, a bone-specific transcription factor, is highly expressed in multiple myeloma cells and is a major driver of multiple myeloma progression in bone. The primary goal of the present study was to identify Runx2-targeting miRNAs that can reduce tumor growth. Expression analysis of a panel of miRNAs in multiple myeloma patient specimens, compared with healthy control specimens, revealed that metastatic multiple myeloma cells express low levels of miR-342 and miR-363 but high levels of Runx2. Reconstituting multiple myeloma cells (CAG) with miR-342 and miR-363 reduced the abundance of Runx2 and the expression of metastasis-promoting Runx2 target genes RANKL and DKK1, and suppressed Runx2 downstream signaling pathways Akt/beta-catenin/survivin, which are required for multiple myeloma tumor progression. Intravenous injection of multiple myeloma cells (5TGM1), stably overexpressing miR-342 and miR-363 alone or together, into syngeneic C57Bl/KaLwRij mice resulted in a significant suppression of 5TGM1 cell growth, decreased osteoclasts and increased osteoblasts, and increased antitumor immunity in the bone marrow, compared with mice injected with 5TGM1 cells expressing a miR-Scramble control. In summary, these results demonstrate that enhanced expression of miR-342 and miR-363 in multiple myeloma cells inhibits Runx2 expression and multiple myeloma growth, decreases osteolysis, and enhances antitumor immunity. Thus, restoring the function of Runx2-targeting by miR-342 and miR-363 in multiple myeloma cells may afford a therapeutic benefit by preventing multiple myeloma progression.Implications: miR-342 and miR-363-mediated downregulation of Runx2 expression in multiple myeloma cells prevents multiple myeloma progression. Mol Cancer Res; 16(7); 1138-48. (c)2018 AACR. PMID- 29592899 TI - Synthetic Lethality of PARP Inhibition and Ionizing Radiation is p53-dependent. AB - PARP inhibitors (PARPi) are potentially effective therapeutic agents capable of inducing synthetic lethality in tumors with deficiencies in homologous recombination (HR)-mediated DNA repair such as those carrying BRCA1 mutations. However, BRCA mutations are rare, the majority of tumors are proficient in HR repair, and thus most tumors are resistant to PARPi. Previously, we observed that ionizing radiation (IR) initiates cytoplasmic translocation of BRCA1 leading to suppression of HR-mediated DNA repair and induction of synthetic PARPi lethality in wild-type BRCA1 and HR-proficient tumor cells. The tumor suppressor p53 was identified as a key factor that regulates DNA damage-induced BRCA1 cytoplasmic sequestration following IR. However, the role of p53 in IR-induced PARPi sensitization remains unclear. This study elucidates the role of p53 in IR induced PARPi cytotoxicity in HR-proficient cancer cells and suggests p53 status may help define a patient population that might benefit from this treatment strategy. Sensitization to PARPi following IR was determined in vitro and in vivo utilizing human breast and glioma tumor cells carrying wild-type BRCA1 and p53, and in associated cells in which p53 function was modified by knockdown or mutation. In breast and glioma cells with proficient HR repair, IR-induced BRCA1 cytoplasmic sequestration, HR repair inhibition, and subsequent PARPi sensitization in vitro and in vivo was dependent upon functional p53.Implications: Implications: p53 status determines PARP inhibitor sensitization by ionizing radiation in multiple BRCA1 and HR-proficient tumor types and may predict which patients are most likely to benefit from combination therapy.

AB - A major challenge in cancer research is to determine the biological and clinical significance of somatic mutations in noncoding regions. This has been studied in terms of recurrence, functional impact, and association to individual regulatory sites, but the combinatorial contribution of mutations to common RNA regulatory motifs has not been explored. Therefore, we developed a new method, MIRA (mutation identification for RNA alterations), to perform an unbiased and comprehensive study of significantly mutated regions (SMR) affecting binding sites for RNA-binding proteins (RBP) in cancer. Extracting signals related to RNA related selection processes and using RNA sequencing (RNA-seq) data from the same specimens, we identified alterations in RNA expression and splicing linked to mutations on RBP binding sites. We found SRSF10 and MBNL1 motifs in introns, HNRPLL motifs at 5' UTRs, as well as 5' and 3' splice-site motifs, among others, with specific mutational patterns that disrupt the motif and impact RNA processing. MIRA facilitates the integrative analysis of multiple genome sites that operate collectively through common RBPs and aids in the interpretation of noncoding variants in cancer. MIRA is available at https://github.com/comprna/miraImplications: The study of recurrent cancer mutations on potential RBP binding sites reveals new alterations in introns, untranslated regions, and long noncoding RNAs that impact RNA processing and provide a new layer of insight that can aid in the interpretation of noncoding variants in cancer genomes.

AB - BACKGROUND: The Countdown for UK Child Survival tracks recent UK child mortality trends and makes recommendations for improvement. METHODS: We used data from the WHO World Mortality Database to calculate mortality from 1970 to 2014 for 0-19 year olds in the UK and a comparable group of wealthy countries (the EU15+). We used Poisson regression models to assess the significance of apparent differences. We extrapolated model coefficients to estimate future disparites between the UK and the EU15+ to 2030. We proposed goals and intermediate indicators to track UK mortality in keeping with the UN Sustainable Development Goals. RESULTS: UK infant mortality continues to track in the worst decile of EU15+ mortality with 1-4 year mortality in the worst quartile. Annual reductions in total UK mortality have been significantly lower than the EU15+ since 1990 for infant, postneonatal and 1-4 year mortality. If current trends persist, by 2030 UK infant mortality and 1-4 year mortality could be respectively 180% and 145% of EU15+ median mortality. UK non-communicable disease (NCD) mortality among 1-4 years and 15-19 years persists in the worst quartile. UK injury mortality continues in the best quartile. A framework of goals and indicators for UK child survival and health is presented. DISCUSSION: UK mortality among under 10 years of age continues to diverge from the EU15+ median, and UK NCD mortality remains persistently poor. We propose a set of goals to improve UK childhood survival by 2030 and an annual Countdown mechanism to monitor progress towards these targets.

AB - Alternative splicing (AS) and alternative promoter (AP) usage expand the repertories of mammalian transcriptome profiles and thus diversify gene functions. However, our knowledge about the extent and functions of AS and AP usage in mouse early embryogenesis remains elusive. Here, by performing whole transcriptome splicing profiling with high-throughput next generation sequencing, we report that AS extensively occurs in embryonic day (E) 7.5 mouse primary germ layers, and may be involved in multiple developmental processes. In addition, numerous RNA splicing factors are differentially expressed and alternatively spliced across the three germ layers, implying the potential importance of AS machinery in shaping early embryogenesis. Notably, AP usage is remarkably frequent at this stage, accounting for more than one quarter (430/1,648) of the total significantly different AS events. Genes generating the 430 AP events participate in numerous biological processes, and include important regulators essential for mouse early embryogenesis, suggesting that AP usage is widely used and might be relevant to mouse germ layer specification. Our data underline the potential significance of AP usage in mouse gastrulation, providing a rich data source and opening another dimension for understanding the regulatory mechanisms of mammalian early development.

AB - Cardiovascular disease is the leading cause of mortality in patients receiving hemodialysis. Cardiovascular events in these patients demonstrate a day-of-week pattern; i.e., they occur more commonly during the last day of the long interdialytic interval and the first session of the week. The hemodialysis process causes acute decreases in cardiac chamber size and pulmonary circulation loading and acute diastolic dysfunction, possibly through myocardial stunning and other non-myocardial-related mechanisms; systolic function, in contrast, is largely unchanged. During interdialytic intervals volume overload, acid-base, and electrolyte shifts, as well as arterial and myocardial wall changes, result in dilatation of right cardiac chambers and pulmonary circulation overload. Recent studies suggest that these alterations are more extended during the long interdialytic interval or the first dialysis session of the week and are associated with excess volume overload or removal, respectively, thus adding a mechanism for the day-of-week pattern of mortality in patients receiving hemodialysis. This review summarizes the existing data from echocardiographic studies of cardiac morphology and function during the hemodialysis session, as well as during the interdialytic intervals. PMID- 29592917 TI - Serious infection across biologic-treated patients with rheumatoid arthritis: results from the British Society for Rheumatology Biologics Register for Rheumatoid Arthritis. AB - OBJECTIVES: To compare the incidence of serious infection (SI) across biologic drugs used to treat rheumatoid arthritis (RA) using data from the British Society for Rheumatology Biologics Register for Rheumatoid Arthritis (BSRBR-RA). METHODS: The BSRBR-RA is a prospective observational cohort study. This analysis included patients with RA starting a new biologic. The primary outcome was SI defined as an infectious event requiring admission to hospital, intravenous antibiotics or resulting in death. Event rates were calculated and compared across biologics using Cox proportional hazards with adjustment for potential confounders. Secondary outcomes were the rate of infection by organ class and 30-day mortality following infection. RESULTS: This analysis included 19 282 patients with 46 771 years of follow-up. The incidence of SI was 5.51 cases per 100 patient years for the entire cohort (95% CI 5.29 to 5.71). Compared with etanercept, tocilizumab had a higher risk of SI (HR 1.22, 95% CI 1.02 to 1.47) and certolizumab pegol a lower risk of SI (HR 0.75, 95% CI 0.58 to 0.97) in the fully adjusted model. The 30-day mortality following SI was 10.4% (95% CI 9.2% to 11.6%). CONCLUSIONS: The rate of SI was lower with certolizumab pegol than etanercept in the primary analysis but the result was no longer significant in several sensitivity analyses performed suggesting residual confounding may account for the observed difference. From these results, it would be wrong to conclude that certolizumab pegol has a lower rate of SI than other biologics; however, the risk does not appear to be significantly higher as has previously been suggested.

AB - BACKGROUND: In 2012, a European initiative called Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is possibly its most devastating extra articular manifestation. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment practices differ widely, within and between nations. OBJECTIVES: To provide recommendations for the diagnosis and treatment of JIA-associated uveitis. METHODS: Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of nine experienced paediatric rheumatologists and three experts in ophthalmology from Europe. Recommendations derived from a validated systematic literature review were evaluated by an Expert Committee and subsequently discussed at two consensus meetings using nominal group techniques. Recommendations were accepted if >80% agreement was reached (including all three ophthalmologists). RESULTS: In total, 22 recommendations were accepted (with >80% agreement among experts): 3 on diagnosis, 5 on disease activity measurements, 12 on treatment and 2 on future recommendations. CONCLUSIONS: The SHARE initiative aims to identify best practices for treatment of patients suffering from JIA associated uveitis. Within this remit, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated by an evidence-informed consensus process to suggest a standard of care for JIA-associated uveitis patients throughout Europe.

AB - T-cell leukemia 1A (TCL1A) single-nucleotide polymorphisms (SNPs) have been associated with aromatase inhibitor-induced musculoskeletal adverse events. We previously demonstrated that TCL1A is inducible by estradiol (E2) and plays a critical role in the regulation of cytokines, chemokines, and Toll-like receptors in a TCL1A SNP genotype and estrogen-dependent fashion. Furthermore, TCLIA SNP dependent expression phenotypes can be "reversed" by exposure to selective estrogen receptor modulators such as 4-hydroxytamoxifen (4OH-TAM). The present study was designed to comprehensively characterize the role of TCL1A in transcriptional regulation across the genome by performing RNA sequencing (RNA seq) and chromatin immunoprecipitation sequencing (ChIP-seq) assays with lymphoblastoid cell lines. RNA-seq identified 357 genes that were regulated in a TCL1A SNP- and E2-dependent fashion with expression patterns that were 4OH-TAM reversible. ChIP-seq for the same cells identified 57 TCL1A binding sites that could be regulated by E2 in a SNP-dependent fashion. Even more striking, nuclear factor-kappaB (NF-kappaB) p65 bound to those same DNA regions. In summary, TCL1A is a novel transcription factor with expression that is regulated in a SNP- and E2-dependent fashion-a pattern of expression that can be reversed by 4OH-TAM. Integrated RNA-seq and ChIP-seq results suggest that TCL1A also acts as a transcriptional coregulator with NF-kappaB p65, an important immune system transcription factor.

AB - Stem cells are undifferentiated cells that play crucial roles during development, growth and regeneration. Traditionally, these cells have been primarily characterised by histology, cell sorting, cell culture and ex vivo methods. However, as stem cells interact in a complex environment within specific tissue niches, there has been increasing interest in examining their in vivo behaviours, particularly in response to injury. Advances in imaging technologies and genetic tools have converged to enable unprecedented access to the endogenous stem cell niche. In this Spotlight article, we highlight how in vivo imaging can probe a range of biological processes that relate to stem cell activity, behaviour and control. PMID- 29592950 TI - The ontogeny, activation and function of the epicardium during heart development and regeneration. AB - The epicardium plays a key role during cardiac development, homeostasis and repair, and has thus emerged as a potential target in the treatment of cardiovascular disease. However, therapeutically manipulating the epicardium and epicardium-derived cells (EPDCs) requires insights into their developmental origin and the mechanisms driving their activation, recruitment and contribution to both the embryonic and adult injured heart. In recent years, studies of various model systems have provided us with a deeper understanding of the microenvironment in which EPDCs reside and emerge into, of the crosstalk between the multitude of cardiovascular cell types that influence the epicardium, and of the genetic programmes that orchestrate epicardial cell behaviour. Here, we review these discoveries and discuss how technological advances could further enhance our knowledge of epicardium-based repair mechanisms and ultimately influence potential therapeutic outcomes in cardiovascular regenerative medicine.

PMID- 29592953 TI - Pharmacological activation of estrogen receptor beta augments innate immunity to suppress cancer metastasis. AB - Metastases constitute the greatest causes of deaths from cancer. However, no effective therapeutic options currently exist for cancer patients with metastasis. Estrogen receptor beta (ERbeta), as a member of the nuclear receptor superfamily, shows potent tumor-suppressive activities in many cancers. To investigate whether modulation of ERbeta could serve as a therapeutic strategy for cancer metastasis, we examined whether the selective ERbeta agonist LY500307 could suppress lung metastasis of triple-negative breast cancer (TNBC) and melanoma. Mechanistically, while we observed that LY500307 potently induced cell death of cancer cells metastasized to lung in vivo, it does not mediate apoptosis of cancer cells in vitro, indicating that the cell death-inducing effects of LY500307 might be mediated by the tumor microenvironment. Pathological examination combined with flow cytometry assays indicated that LY500307 treatment induced significant infiltration of neutrophils in the metastatic niche. Functional experiments demonstrated that LY500307-treated cancer cells show chemotactic effects for neutrophils and that in vivo neutrophil depletion by Ly6G antibody administration could reverse the effects of LY500307-mediated metastasis suppression. RNA sequencing analysis showed that LY500307 could induce up regulation of IL-1beta in TNBC and melanoma cells, which further triggered antitumor neutrophil chemotaxis. However, the therapeutic effects of LY500307 treatment for suppression of lung metastasis was attenuated in IL1B-/- murine models, due to failure to induce antitumor neutrophil infiltration in the metastatic niche. Collectively, our study demonstrated that pharmacological activation of ERbeta could augment innate immunity to suppress cancer metastatic colonization to lung, thus providing alternative therapeutic options for cancer patients with metastasis. PMID- 29592954 TI - Synergistic activity of cosecreted natural products from amoebae-associated bacteria. AB - Investigating microbial interactions from an ecological perspective is a particularly fruitful approach to unveil both new chemistry and bioactivity. Microbial predator-prey interactions in particular rely on natural products as signal or defense molecules. In this context, we identified a grazing-resistant Pseudomonas strain, isolated from the bacterivorous amoeba Dictyostelium discoideum. Genome analysis of this bacterium revealed the presence of two biosynthetic gene clusters that were found adjacent to each other on a contiguous stretch of the bacterial genome. Although one cluster codes for the polyketide synthase producing the known antibiotic mupirocin, the other cluster encodes a nonribosomal peptide synthetase leading to the unreported cyclic lipopeptide jessenipeptin. We describe its complete structure elucidation, as well as its synergistic activity against methicillin-resistant Staphylococcus aureus, when in combination with mupirocin. Both biosynthetic gene clusters are regulated by quorum-sensing systems, with 3-oxo-decanoyl homoserine lactone (3-oxo-C10-AHL) and hexanoyl homoserine lactone (C6-AHL) being the respective signal molecules. This study highlights the regulation, richness, and complex interplay of bacterial natural products that emerge in the context of microbial competition.

AB - Although the hippocampus is one of the most studied structures in the human brain, limited quantitative data exist on its 3D organization, anatomical variability, and effects of disease on its subregions. Histological studies provide restricted reference information due to their 2D nature. In this paper, high-resolution (~200 * 200 * 200 MUm3) ex vivo MRI scans of 31 human hippocampal specimens are combined using a groupwise diffeomorphic registration approach into a 3D probabilistic atlas that captures average anatomy and anatomic variability of hippocampal subfields. Serial histological imaging in 9 of the 31 specimens was used to label hippocampal subfields in the atlas based on cytoarchitecture. Specimens were obtained from autopsies in patients with a clinical diagnosis of Alzheimer's disease (AD; 9 subjects, 13 hemispheres), of other dementia (nine subjects, nine hemispheres), and in subjects without dementia (seven subjects, nine hemispheres), and morphometric analysis was performed in atlas space to measure effects of age and AD on hippocampal subfields. Disproportional involvement of the cornu ammonis (CA) 1 subfield and stratum radiatum lacunosum moleculare was found in AD, with lesser involvement of the dentate gyrus and CA2/3 subfields. An association with age was found for the dentate gyrus and, to a lesser extent, for CA1. Three-dimensional patterns of variability and disease and aging effects discovered via the ex vivo hippocampus atlas provide information highly relevant to the active field of in vivo hippocampal subfield imaging. PMID- 29592957 TI - Intra-Cardiac Release of Extracellular Vesicles Shapes Inflammation Following Myocardial Infarction. AB - RATIONALE: A rapid and massive influx of inflammatory cells occurs into ischemic area after myocardial infarction (MI), resulting in local release of cytokines and growth factors. Yet, the mechanisms regulating their production are not fully explored. The release of extracellular vesicles (EVs) in the interstitial space curbs important biological functions, including inflammation, and influences the development of cardiovascular diseases. To date, there is no evidence for in situ release of cardiac EVs after MI. OBJECTIVE: The present study tested the hypothesis that local EV generation in the infarcted heart coordinates cardiac inflammation after MI. METHODS AND RESULTS: Coronary artery ligation in mice transiently increases EV levels in the left ventricle when compared with sham animals. EVs from infarcted hearts were characterized as large vesicles (252+/-18 nm) expressing cardiomyocyte and endothelial markers and small EVs (118+/-4 nm) harboring exosomal markers, such as CD (cluster of differentiation) 63 and CD9. Cardiac large EVs generated after MI, but not small EVs or sham EVs, increased the release of IL (interleukin)-6, CCL (chemokine ligand) 2, and CCL7 from fluorescence-activated cell-sorted Ly6C+ cardiac monocytes. EVs of similar diameter were also isolated from fragments of interventricular septum obtained from patients undergoing aortic valve replacement, thus supporting the clinical relevance of our findings in mice. CONCLUSIONS: The present study demonstrates that acute MI transiently increases the generation of cardiac EVs characterized as both exosomes and microvesicles, originating mainly from cardiomyocytes and endothelial cells. EVs accumulating in the ischemic myocardium are rapidly taken up by infiltrating monocytes and regulate local inflammatory responses.

PMID- 29592958 TI - Use of haloperidol versus atypical antipsychotics and risk of in-hospital death in patients with acute myocardial infarction: cohort study. AB - OBJECTIVE: To compare the risk of in-hospital mortality associated with haloperidol compared with atypical antipsychotics in patients admitted to hospital with acute myocardial infarction. DESIGN: Cohort study using a healthcare database. SETTING: Nationwide sample of patient data from more than 700 hospitals across the United States. PARTICIPANTS: 6578 medical patients aged more than 18 years who initiated oral haloperidol or oral atypical antipsychotics (olanzapine, quetiapine, risperidone) during a hospital admission with a primary diagnosis of acute myocardial infarction between 2003 and 2014. MAIN OUTCOME MEASURE: In-hospital mortality during seven days of follow-up from treatment initiation. RESULTS: Among 6578 patients (mean age 75.2 years) treated with an oral antipsychotic drug, 1668 (25.4%) initiated haloperidol and 4910 (74.6%) initiated atypical antipsychotics. The mean time from admission to start of treatment (5.3 v 5.6 days) and length of stay (12.5 v 13.6 days) were similar, but the mean treatment duration was shorter in patients using haloperidol compared with those using atypical antipsychotics (2.4 v 3.9 days). 1:1 propensity score matching was used to adjust for confounding. In intention to treat analyses with the matched cohort, the absolute rate of death per 100 person days was 1.7 for haloperidol (129 deaths) and 1.1 for atypical antipsychotics (92 deaths) during seven days of follow-up from treatment initiation. The survival probability was 0.93 in patients using haloperidol and 0.94 in those using atypical antipsychotics at day 7, accounting for the loss of follow-up due to hospital discharge. The unadjusted and adjusted hazard ratios of death were 1.51 (95% confidence interval 1.22 to 1.85) and 1.50 (1.14 to 1.96), respectively. The association was strongest during the first four days of follow-up and decreased over time. By day 5, the increased risk was no longer evident (1.12, 0.79 to 1.59). In the as-treated analyses, the unadjusted and adjusted hazard ratios were 1.90 (1.43 to 2.53) and 1.93 (1.34 to 2.76), respectively. CONCLUSION: The results suggest a small increased risk of death within seven days of initiating haloperidol compared with initiating an atypical antipsychotic in patients with acute myocardial infarction. Although residual confounding cannot be excluded, this finding deserves consideration when haloperidol is used for patients admitted to hospital with cardiac morbidity. PMID- 29592961 TI - Lysosome-Mediated Plasma Membrane Repair Is Dependent on the Small GTPase Arl8b and Determines Cell Death Type in Mycobacterium tuberculosis Infection. AB - Mycobacterium tuberculosis is an extremely successful pathogen, and its success is widely attributed to its ability to manipulate the intracellular environment of macrophages. A central phenomenon of tuberculosis pathology enabling immune evasion is the capacity of virulent M. tuberculosis (H37Rv) to induce macrophage necrosis, which facilitates the escape of the mycobacteria from the macrophage and spread of infection. In contrast, avirulent M. tuberculosis (H37Ra) induces macrophage apoptosis, which permits Ag presentation and activation of adaptive immunity. Previously, we found that H37Rv induces plasma membrane microdisruptions, leading to necrosis in the absence of plasma membrane repair. In contrast, H37Ra permits plasma membrane repair, which changes the host cell death modality to apoptosis, suggesting that membrane repair is critical for sequestering the pathogen in apoptotic vesicles. However, mechanisms of plasma membrane repair induced in response to M. tuberculosis infection remain unknown. Plasma membrane repair is known to induce a Ca2+-mediated signaling, which recruits lysosomes to the area of damaged plasma membrane sites for its resealing. In this study, we found that the small GTPase Arl8b is required for plasma membrane repair by controlling the exocytosis of lysosomes in cell lines and in human primary macrophages. Importantly, we found that the Arl8b secretion pathway is crucial to control the type of cell death of the M. tuberculosis infected macrophages. Indeed, Arl8b-depleted macrophages infected with avirulent H37Ra undergo necrotic instead of apoptotic cell death. These findings suggest that membrane repair mediated by Arl8b may be an important mechanism distinguishing avirulent from virulent M. tuberculosis-induced necrotic cell death. PMID- 29592962 TI - Microcrystalline Tyrosine and Aluminum as Adjuvants in Allergen-Specific Immunotherapy Protect from IgE-Mediated Reactivity in Mouse Models and Act Independently of Inflammasome and TLR Signaling. AB - Allergen immunotherapy (AIT) is the only modality that can modify immune responses to allergen exposure, but therapeutic coverage is low. One strategy to improve AIT safety and efficacy is the use of new or improved adjuvants. This study investigates immune responses produced by microcrystalline tyrosine (MCT) based vaccines as compared with conventional aluminum hydroxide (alum). Wild type, immune-signaling-deficient, and TCR-transgenic mice were treated with different Ags (e.g., OVA and cat dander Fel d 1), plus MCT or alum as depot adjuvants. Specific Ab responses in serum were measured by ELISA, whereas cytokine secretion was measured both in culture supernatants by ELISA or by flow cytometry of spleen cells. Upon initiation of AIT in allergic mice, body temperature and further clinical signs were used as indicators for anaphylaxis. Overall, MCT and alum induced comparable B and T cell responses, which were independent of TLR signaling. Alum induced stronger IgE and IL-4 secretion than MCT. MCT and alum induced caspase-dependent IL-1beta secretion in human monocytes in vitro, but inflammasome activation had no functional effect on inflammatory and Ab responses measured in vivo. In sensitized mice, AIT with MCT-adjuvanted allergens caused fewer anaphylactic reactions compared with alum-adjuvanted allergens. As depot adjuvants, MCT and alum are comparably effective in strength and mechanism of Ag-specific IgG induction and induction of T cell responses. The biocompatible and biodegradable MCT seems therefore a suitable alternative adjuvant to alum-based vaccines and AIT. PMID- 29592963 TI - Single Degranulations in NK Cells Can Mediate Target Cell Killing. AB - NK cells are cytotoxic lymphocytes important in defense against viral infection and cancer. NK cells mediate cytotoxicity predominantly through directed secretion of lytic granules, which are specialized lysosome-related organelles, containing effector molecules such as perforin and granzymes. Although many requirements for lytic granule transport to, and secretion at, the NK cell lytic synapse are known, the minimum number of degranulation events required by an NK cell to kill its target is unknown. We performed high-resolution four-dimensional confocal microscopy of human NK-target cell conjugates to quantify NK cell degranulation (using a degranulation indicator, LAMP-1-pHluorin) as well as target cell death. Despite containing almost 200 granules, we found that an individual NK cell needed only two to four degranulation events, on average, to mediate target cell death. Although NK cells released approximately one-tenth of their total lytic granule reserve upon a single target, they required just over one-hundredth of their total lytic granules to kill a target cell. Importantly, the kinetics of NK cell killing correlated to the size of and the amount of effector molecules contained within lytic granules, as well as the temporal, but not spatial, organization of degranulation events. Thus, our study answers a fundamental question as to how many degranulation events it takes for a human NK cell to kill its target. PMID- 29592964 TI - Local Stimulation of Liver Sinusoidal Endothelial Cells with a NOD1 Agonist Activates T Cells and Suppresses Hepatitis B Virus Replication in Mice. AB - Functional maturation of liver sinusoidal endothelial cells (LSECs) induced by a NOD1 ligand (diaminopimelic acid [DAP]) during viral infection has not been well defined. Thus, we investigated the role of DAP-stimulated LSEC maturation during hepatitis B virus (HBV) infection and its potential mechanism in a hydrodynamic injection (HI) mouse model. Primary LSECs were isolated from wild-type C57BL/6 mice and stimulated with DAP in vitro and in vivo and assessed for the expression of surface markers as well as for their ability to promote T cell responses via flow cytometry. The effects of LSEC maturation on HBV replication and expression and the role of LSECs in the regulation of other immune cells were also investigated. Pretreatment of LSECs with DAP induced T cell activation in vitro. HI-administered DAP induced LSEC maturation and subsequently enhanced T cell responses, which was accompanied by an increased production of intrahepatic cytokines, chemokines, and T cell markers in the liver. The HI of DAP significantly reduced the HBsAg and HBV DNA levels in the mice. Importantly, the DAP-induced anti-HBV effect was impaired in the LSEC-depleted mice, which indicated that LSEC activation and T cell recruitment into the liver were essential for the antiviral function mediated by DAP application. Taken together, the results showed that the Ag-presenting ability of LSECs was enhanced by DAP application, which resulted in enhanced T cell responses and inhibited HBV replication in a mouse model. PMID- 29592965 TI - Elastin Shapes Small Molecule Distribution in Lymph Node Conduits. AB - The spatial and temporal Ag distribution determines the subsequent T cell and B cell activation at the distinct anatomical locations in the lymph node (LN). It is well known that LN conduits facilitate small Ag distribution in the LN, but the mechanism of how Ags travel along LN conduits remains poorly understood. In C57BL/6J mice, using FITC as a fluorescent tracer to study lymph distribution in the LN, we found that FITC preferentially colocalized with LN capsule-associated (LNC) conduits. Images generated using a transmission electron microscope showed that LNC conduits are composed of solid collagen fibers and are wrapped with fibroblastic cells. Superresolution images revealed that high-intensity FITC is typically colocalized with elastin fibers inside the LNC conduits. Whereas tetramethylrhodamine isothiocyanate appears to enter LNC conduits as effectively as FITC, fluorescently-labeled Alexa-555-conjugated OVA labels significantly fewer LNC conduits. Importantly, injection of Alexa-555-conjugated OVA with LPS substantially increases OVA distribution along elastin fibers in LNC conduits, indicating immune stimulation is required for effective OVA traveling along elastin in LN conduits. Finally, elastin fibers preferentially surround lymphatic vessels in the skin and likely guide fluid flow to the lymphatic vessels. Our studies demonstrate that fluid or small molecules are preferentially colocalized with elastin fibers. Although the exact mechanism of how elastin fibers regulate Ag trafficking remains to be explored, our results suggest that elastin can be a potentially new target to direct Ag distribution in the LN during vaccine design.

PMID- 29592967 TI - Effect of Achieved Systolic Blood Pressure on Cardiovascular Outcomes in Patients With Type 2 Diabetes: A Population-Based Retrospective Cohort Study. AB - OBJECTIVE: The objective of this study was to compare the incidence of cardiovascular disease (CVD) among patients with type 2 diabetes mellitus (T2DM) with treated hypertension who achieved systolic blood pressures (SBPs) of <120, <130, and <140 mmHg after an increase in their antihypertensive regimen. RESEARCH DESIGN AND METHODS: A retrospective cohort study was conducted on 28,014 primary care adult patients with T2DM with no prior diagnosis of CVD and who achieved SBP readings <140 mmHg after an increase in the number of antihypertensive medications prescribed. Using an extension of propensity score matching, a total of 2,079, 10,851, and 15,084 matched patients with achieved SBP measurements of <120, <130, and <140 mmHg were identified. The association between achieved SBP and incident CVD were evaluated using Cox regressions. Subgroup analyses were conducted by stratifying patients' baseline characteristics. RESULTS: Over a median follow-up period of 4.8 years, the incidence of CVD in patients with achieved SBP measures of <120, <130, and <140 mmHg were 318 (15.3%; incidence rate [IR] 34.3/1,000 person-years [PY]), 992 (9.1%; IR 20.4/1,000 PY), and 1,635 (10.8%; IR 21.4/1,000 PY). Achieved SBP <120 mmHg was associated with a higher risk of CVD compared with achieved SBP <130 mmHg (hazard ratio [HR] 1.75 [95% CI 1.53, 2.00]) and achieved SBP <140 mmHg (HR 1.67 [95% CI 1.46, 1.90]). There was a significant reduction in CVD risk in patients <65 years (HR 0.81 [95% CI 0.69, 0.96]) but no difference for other patients, including patients >=65 years, who achieved SBP <130 mmHg when compared with the group that achieved SBP <140 mmHg. CONCLUSIONS: Our findings support a SBP treatment target of 140 mmHg and suspect no risk reduction attenuation on CVD for lower SBP targets (<120 or <130 mmHg) for most patients with uncomplicated T2DM. A randomized control trial is still needed to confirm these findings. PMID- 29592968 TI - NHS should work with WhatsApp to create a new service. PMID- 29592969 TI - Association of Birthplace and Coronary Heart Disease and Stroke Among US Adults: National Health Interview Survey, 2006 to 2014. AB - BACKGROUND: The proportion of foreign-born US adults has almost tripled since 1970. However, less is known about the cardiovascular morbidity by birthplace among adults residing in the United States. This study's objective was to compare the prevalence of coronary heart disease (CHD) and stroke among US adults by birthplace. METHODS AND RESULTS: We used data from the 2006 to 2014 National Health Interview Survey. Birthplace was categorized as United States or foreign born. Foreign born was then grouped into 6 birthplace regions. We defined CHD and stroke as ever being told by a physician that she or he had CHD or stroke. We adjusted for select demographic and health characteristics in the analysis. Of US adults, 16% were classified as foreign born. Age-standardized prevalence of both CHD and stroke were higher among US- than foreign-born adults (CHD: 8.2% versus 5.5% for men and 4.8% versus 4.1% for women; stroke: 2.7% versus 2.1% for men and 2.7% versus 1.9% for women; all P<0.05). Comparing individual regions with those of US- born adults, CHD prevalence was lower among foreign-born adults from Asia and Mexico, Central America, or the Caribbean. For stroke, although men from South America or Africa had the lowest prevalence, women from Europe had the lowest prevalence. Years of living in the United States was not related to risk of CHD or stroke after adjustment with demographic and health characteristics. CONCLUSIONS: Overall, foreign-born adults residing in the United States had a lower prevalence of CHD and stroke than US-born adults. However, considerable heterogeneity of CHD and stroke risk was found by region of birth. PMID- 29592970 TI - Spatio-temporal MAPK dynamics mediate cell behavior coordination during fungal somatic cell fusion. AB - Mitogen-activated protein kinases (MAPKs) are conserved regulators of proliferation, differentiation and adaptation in eukaryotic cells. Their activity often involves changes in their subcellular localization, indicating an important role for these spatio-temporal dynamics in signal transmission. A striking model illustrating these dynamics is somatic cell fusion in Neurospora crassa Germinating spores of this fungus rapidly alternate between signal sending and receiving, thereby establishing a cell-cell dialog, which involves the alternating membrane recruitment of the MAPK MAK-2 in both fusion partners. Here, we show that the dynamic translocation of MAK-2 is essential for coordinating the behavior of the fusion partners before physical contact. The activation and function of the kinase strongly correlate with its subcellular localization, indicating a crucial contribution of the MAPK dynamics in establishing regulatory feedback loops, which establish the oscillatory signaling mode. In addition, we provide evidence that MAK-2 not only contributes to cell-cell communication, but also mediates cell-cell fusion. The MAK-2 dynamics significantly differ between these two processes, suggesting a role for the MAPK in switching of the cellular program between communication and fusion. PMID- 29592972 TI - Drug-induced movement disorder and confusion associated with duloxetine. AB - A 60-year-old woman with major depressive disorder, developed high blood pressure, confusion and dyskinesias of face, neck and jaw, following an increase in her dose of duloxetine. Routine blood tests including toxic, infective and metabolic workup were unremarkable. Cerebrospinal fluid analysis and electroencephalogram were also normal. MRI brain showed bilaterally symmetrical diffusion-restricted areas in deep cerebral white matter. Duloxetine was held on suspicion of drug adverse effect. She had complete resolution of symptoms within 48 hours and resolution of MRI brain changes over 6 weeks. Serotonin norepinephrine reuptake inhibitors such as duloxetine may have the potential to cause drug-induced movement disorders, confusion and high blood pressure and should be used cautiously especially in elderly. PMID- 29592971 TI - The Joubert syndrome protein ARL13B binds tubulin to maintain uniform distribution of proteins along the ciliary membrane. AB - Cilia-mediated signal transduction involves precise targeting and localization of selected molecules along the ciliary membrane. However, the molecular mechanism underlying these events is unclear. The Joubert syndrome protein ARL13B is a membrane-associated G-protein that localizes along the cilium and functions in protein transport and signaling. We identify tubulin as a direct interactor of ARL13B and demonstrate that the association occurs via the G-domain and independently from the GTPase activity of ARL13B. The G-domain is necessary for the interaction of ARL13B with the axoneme both in vitro and in vivo We further show that exogenously expressed mutants lacking the tubulin-binding G-domain (ARL13B-DeltaGD) or whose GTPase domain is inactivated (ARL13B-T35N) retain ciliary localization, but fail to rescue ciliogenesis defects of null Arl13bhnn mouse embryonic fibroblasts (MEFs). However, while ARL13B-DeltaGD and the membrane proteins Smoothened (SMO) and Somatostatin receptor-3 (SSTR3) distribute unevenly along the cilium of Arl13bhnn MEFs, ARL13B-T35N distributes evenly along the cilium and enables the uniform distribution of SMO and SSTR3. Thus, we propose a so far unknown function of ARL13B in anchoring ciliary membrane proteins to the axoneme through the direct interaction of its G-domain with tubulin.

AB - We report a 27-year-old woman, a known case of classical migraine headache, on oral contraceptive pills. She had a severe episode of migraine with visual aura attack, which continued late into the night. The next early morning, her headache persisted and she developed abrupt onset of dysarthria, right hemiparaesthesias. She attributed symptoms to her long-standing headache problem, and hence did not seek medical help for the next two weeks. The symptoms persisted despite her headache subsiding over the next 24 hours. She worsened 2 weeks later during another such episode of headache. This time, she developed right hemiparesis. The patient was admitted with provisional diagnosis of stroke. MRI of the brain showed left temporoparietal lesion and was radiologically compatible with cortical laminar necrosis.Extensive work-up was done to rule out other causes of young stroke. The patient improved with antiplatelets, antimigraine prophylaxis and stroke rehabilitation therapy. PMID- 29592974 TI - Sodium nitroprusside, a lifesaving treatment for neonatal hypertension: an Irish experience. AB - We present a 30+2-weeks-old (30 weeks and 2 days) male, twin 1, born by emergency caesarean section due to twin-twin transfusion syndrome (absent end-diastolic flow and cardiac anomaly in twin 2) presenting with hypertensive crisis on day 3. He was already on milrinone and propranolol. His echocardiogram showed poor left ventricular contractility and after cardiology consultation received sodium nitroprusside, which eventually saved his life by decreasing his blood pressure and improving cardiac function. As sodium nitroprusside is very rarely used for hypertensive crisis in neonates, we would like to share our experiences on dosage, challenges in administration due to its fast onset of action, criteria for monitoring for complications and finally weaning. Baby developed severe bilateral periventricular leukomalacia as a potential complication of hypertensive crisis, preceded by bilateral periventricular flare secondary to twin-twin transfusion. PMID- 29592975 TI - Fulminant hepatic failure in the setting of progressive ANCA-associated vasculitis associated with a rare alpha-1 antitrypsin phenotype, 'PiEE'. AB - Abnormalities in alpha-1 antitrypsin (AAT) proteins are risk factors for human disease. While the most common is AAT deficiency, a genetic disorder associated with chronic obstructive pulmonary disease, additional disorders associated with AAT abnormalities are increasingly recognised. We describe a middle-aged woman who presented with fulminant hepatic and multiorgan failure. Evaluation revealed the patient to have a rare AAT phenotype PiEE. Her clinical presentation was consistent with antineutrophilic cytoplasmic antibody-associated vasculitis, and her history suggested features of panniculitis. This is the first description of this rare homozygous AAT phenotype and possible disease associations with the 'E' protein. Given that abnormal AAT are under-recognised, and that new mutations and phenotypes continue to be identified, we will need to expand on our knowledge base and report clinical manifestations associated with these abnormal phenotypes. PMID- 29592976 TI - Localisation of ectopic mediastinal parathyroid adenoma by 18F-fluorocholine PET/CT. AB - We report the case of two patients with newly diagnosed primary hyperparathyroidism: a 40-year-old woman during pregnancy and a 60-year-old man with initial hypercalcaemic crisis. In the first case, a bilateral neck exploration with parathyroidectomy during the second trimester of pregnancy was unsuccessful and the patient remained hypercalcaemic. Postpartum imaging assessment with technetium (99mTc)-sestamibi scintigraphy could not supply conclusive diagnostic results. The use of 18F-fluorocholine (FCH) positron emission tomography (PET)/CT provided the accurate localisation of an ectopic parathyroid adenoma in the anterior mediastinum which was successfully resected by a thoracoscopic approach. In the second case, 99mTc-sestamibi scintigraphy was inconclusive as well and FCH-PET/CT localised an ectopic parathyroid adenoma in the mediastinum and thus bilateral neck exploration could be spared. Both patients had surgical cure of their disease. PMID- 29592977 TI - Artery of Percheron: an unusual stroke presentation. AB - An 86-year-old woman was admitted with multiple episodes of transient loss of consciousness. She was initially treated for seizures, and stroke was not considered likely. MRI on the same day of admission showed acute bilateral medial thalamic infarcts in keeping with the Artery of Percheron (AOP) territory infarcts. Investigation for polycythaemia and thrombocytosis showed JAK2 positive myeloproliferative neoplasm.A diagnosis of AOP infarction is often missed or delayed because it is rare and presents with variable neurological symptoms. Initial imaging in the form of CT is often negative, and some report that initial MRI findings may also be normal.An awareness of a wide range of differential diagnoses alongside a multi-modality imaging approach is required to reach a diagnosis.Although there are several other case reports of AOP infarction in the literature, this is the first to present with transient symptoms initially mistaken for seizure activity. PMID- 29592978 TI - Hypoglossal nerve stimulation for obstructive sleep apnoea in a patient with previous tongue laceration. AB - Upper airway stimulation of the tongue using an implantable neurostimulator has recently been approved for select patients with moderate to severe obstructive sleep apnoea (OSA) and intolerance to continuous positive airway pressure therapy. Effective implantation depends on the integrity of the hypoglossal nerve as well as the tongue musculature, notably the genioglossus. Prior trauma to either of these structures may be viewed as a relative contraindication to implantation. We describe a case of successful right hypoglossal nerve implantation in a patient with a history of left cardiac pacemaker placement and severe left penetrating tongue trauma with decreased mobility from contracture and deviation mimicking a hypoglossal nerve palsy. Preoperative and postoperative apnoea-hypopnoea index values were 52/hour and 5/hour, respectively. Prior soft tissue trauma to the tongue may not necessarily preclude surgical candidacy for upper airway stimulation in patients with OSA. PMID- 29592979 TI - Spondylodiscitis in a 54-year-old female scuba diver. AB - A 54-year-old woman presented to a Sports Physician with a 4-year history of haemochromatosis, and she had a medical history that included a congenital spondylolisthesis resulting in a fusion of L4-S1 at age 16 years, episodic mechanical low back pain and an absence of other significant musculoskeletal symptoms. On presentation, she reported 18 months of severe low back pain that started after a scuba diving trip. After the onset of this low back pain, she developed gastrointestinal symptoms from Salmonella The gastrointestinal symptoms improved with a course of antibiotics, but the back pain persisted in spite of analgesics, non-steroidal anti-inflammatories and several attempts at different conservative management. CT imaging ordered by the Sports Physician demonstrated an erosive spondylodiscitis of L2/3 that was not present on initial investigations. However, even in the presence of significant bony changes, the patient was successfully treated with targeted conservative therapy. PMID- 29592980 TI - Metastatic pheochromocytoma in MEN 2A: A rare association. AB - A 45-year-old woman was diagnosed as having multiple endocrine neoplasia type 2A in 2014. She had bilateral pheochromocytoma, medullary thyroid carcinoma and biopsy-proven cutaneous lichen amyloidosis in the interscapular area. She underwent bilateral adrenalectomy; following which, she achieved clinical and biochemical remission. She was planned for total thyroidectomy at a later date; however, she was lost to follow-up. She presented to us again in December 2016 with abdominal pain. Examination revealed hypertension with postural drop. Positron emission tomography scan showed Ga68 and fluorodeoxyglucose (FDG)-avid suprarenal, hepatic, peritoneal and mesenteric masses with abdominal lymph nodes. Twenty-four-hour urinary metanephrines/normetanephrines were elevated. Serum calcitonin was as high as it was 2-1/2 years ago. Ultrasonography-guided fine needle aspiration cytology (FNAC) from the liver mass revealed neuroendocrine cells that did not stain for calcitonin. Hence, a diagnosis of metastatic pheochromocytoma was made. She underwent total thyroidectomy and was started on cyclophosphamide, vincristine, dacarbazine-based chemotherapy regimen.

We present a case of a 67-year-old Pakistani man, diabetic for 20 years presented at our healthcare centre. While awaiting his culture sensitivity report, he was prescribed an empiric antibiotic therapy. Patient then travelled to Saudi Arabia for pilgrimage 3 days later with growth of Staphylococcus aureus and Proteus species in culture and sensitivity report; during his travel, he walked barefoot and the infected wart aggravated with severe burn. Patient continued empiric treatment for 14 days. On his arrival, infected wart worsened with dead burnt skin, heavy purulent discharge on plantar region. X-rays revealed marked arthritic changes.

A man with no history of infection developed cryptococcal meningitis and a right parahilar cryptococcal mass. Antifungal treatment led to infection control, although there was presence of neurological sequelae. After 3 years, thoracic CT revealed bilateral ground glass opacities and a crazy paving pattern. Transparietal needle biopsy showed proteinaceous alveolar deposits, confirming the diagnosis of PAP. A high titre of serum anti-GM-CSF autoantibodies was found. No specific treatment was started, and radiological lesions decreased progressively. Cryptococcal infection may occur in PAP and in patients with anti-GM-CSF antibodies without PAP. These antibodies dysregulate phagocytosis in monocytes and macrophages, possibly leading to opportunistic infections in previously healthy subjects. PMID- 29592983 TI - Rare cause of fever of unknown origin: gastrointestinal stromal tumour. AB - A 44-year-old man presented with fever (low to high grade) for 2-month duration despite treatment with oral antibiotics and antipyretics. Further, enquiry did not yield any potentially explanatory clues to a diagnosis. Physical examination revealed only left axillary lymphadenopathy, but was otherwise unremarkable. A number of diagnosis included tuberculosis, malignancy, lymphoma, connective disease disorder and infective endocarditis. Further evaluation revealed severe anaemia due to iron deficiency which was supported with blood transfusion and oral iron supplementation. Septic work-up including blood cultures and urine culture sterile and procalcitonin, but all these proved negative. Transthoracic echocardiography followed by transoesophageal echocardiography did not reveal any vegetations suggestive of infective endocarditis. Contrast-enhanced CT of chest and abdomen showed a polypoidal mass in the caecum. Lymph node biopsy from left axillary lymph node showed changes consistent with reactive hyperplasia. A bone marrow biopsy was inconclusive. Mantoux test was negative. A colonoscopy revealed a polypoidal growth arising from caecum with dull-looking mucosa. Biopsy of the mass suggested a leiomyoma. Positron emission tomography CT showed fluorodeoxyglucose (FDG)-avid caecal mass with FDG-avid mesenteric lymph nodes (figure 1). Inspite of extensive work-up, we could not find a source of the fever except for caecal mass. Thus, in the absence of other explanatory findings, a decision for resection of the mass was taken. A laparoscopic right hemicolectomy done with primary anastomosis. Histology confirmed a gastrointestinal stromal tumour (figure 2, which was smooth muscle actin positive (figure 3), S-100 positive, vimentin positive, but c-KIT negative (figure 4), CD34 positive and desmin negative. Additional immunohistochemistry and gene mutational analysis could not be done due to resource limitations. The postoperative course was good, and the patient was followed for 9 months after surgery with good clinical recovery and no further fever. This case illustrates the need for high index of suspicion to diagnose malignancy as cause of fever. PMID- 29592984 TI - A rare cause of postpartum headache. AB - Postpartum women can develop headache, and their assessment requires a thorough and multidisciplinary approach. If the headache is unresponsive to treatment and accompanied by neurological deficit, neuroimaging needs to be undertaken to rule out other life-threatening causes. 1 We present a case of 35-year-old woman with pre-eclampsia and diet-controlled gestational diabetes mellitus, who had normal vaginal delivery at 40 weeks. She had an epidural analgesia for pain relief during labour, but had inadvertent dural puncture during the procedure and developed headache 24 hours after delivery. The headache was managed conservatively and she was discharged home, but was readmitted 8 days later with worsening headache. The headache was postural on admission but became continuous, developed neurological symptoms in the form of ataxic hemiparesis and convulsions. After neuroimaging, she was found to have cerebral venous sinus thrombosis. She was commenced on anticoagulants and anticonvulsants and made a complete recovery. PMID- 29592986 TI - Pleomorphic adenoma of nasal septum: a rare case. AB - The most common benign tumour of the major salivary glands is the pleomorphic adenoma. They are seen rarely in the minor salivary glands, usually in hard palate, soft palate and nasopharynx. Pleomorphic adenomas in nasal cavity are unusual and may be misdiagnosed because they have predominant myoepithelial cellularity and fewer myxoid stromata compared with those elsewhere. We present a case of 38-year-old male with a 2-year history of left nasal obstruction and epistaxis since 6 months. Diagnostic nasal endoscopic examination showed a soft lobulated mass in left nasal cavity attached to anterior part of the septum. Radiological examination demonstrated soft tissue mass filling left nasal cavity with an eroded septum. The biopsy from the mass was suggestive of pleomorphic adenoma and was resected endoscopically. Histopathological examination was consistent with pleomorphic adenoma. These are rare tumours of the nasal cavity and can be managed effectively with the endoscopic approach. PMID- 29592985 TI - Caffeine to prevent respiratory failure and improve outcome in infant pertussis. AB - Pertussis remains a dangerous disease for children around the world, especially for infants less than 6 months old. In this age group, high mortality and morbidity have been linked to the effects of the pertussis toxin, including lymphocytosis, pulmonary hyperviscosity and pulmonary hypertension. This paper reports on an infant with pertussis who received therapeutic caffeine. Caffeine might improve outcomes in pertussis by preventing apnoea, improving respiratory drive and decreasing pulmonary complications. PMID- 29592987 TI - Seizure-induced unilateral posterior dislocation of the shoulder: a diagnosis not to be missed. AB - A man in his mid-50s with a history of bladder carcinoma presented to the Emergency Department (ED) following a witnessed tonic-clonic seizure. Computed Tomography (CT) scanning of his brain revealed an indeterminate mass lesion in the left parietal region. The patient described bilateral shoulder pain prompting plain film radiographs with axial views, but no obvious abnormality was identified by the ED staff. Staging CT scanning did not reveal any evidence of underlying malignancy but revealed dislocation of the left humeral head with a large reverse Hill-Sachs lesion and posteriorly displaced reverse Bankart lesion. Manipulation under anaesthesia and closed reduction of the left shoulder was undertaken successfully. This case report reminds the clinician to maintain a high index of suspicion for posterior dislocation of the shoulder following seizures and to perform appropriate imaging promptly. PMID- 29592988 TI - Paediatric forearm fracture with a twist: a proximal radioulnar translocation combined with radial head fracture. AB - A 10-year-old girl presented to the emergency department with proximal radioulnar translocation and radial head fracture, after fall onto an outstretched hand. Open reduction was used to reduce and stabilise the elbow joint after which the radial head was fixated by Kirschner wires. Three months after surgery, full range of motion was regained and union of the radial head was achieved. Proximal radioulnar translocation is a rare injury which is often missed on initial radiographs. Persistent restriction of forearm rotation with seemingly normal elbow configuration must trigger to take a closer look at the relationship between the ulna, radius and distal humerus. We show that early diagnosis and treatment of a proximal radioulnar translocation associated with a radial head fracture results in an excellent functional outcome. PMID- 29592989 TI - Severe acute haemolytic anaemia associated with severe methaemoglobinaemia in a G6PD-deficient man. AB - Methaemoglobin is a form of haemoglobin in which the ferrous (Fe2+) ion contained in the iron-porphyrin complex of haem is oxidised to its ferric (Fe3+) state. Methaemoglobinaemia, the presence of methaemoglobin in the blood, is most commonly treated with methylene blue. However, methylene blue cannot be used in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency as it is ineffective in such patients and it can worsen G6PD deficiency haemolysis. We report the case of a 30-year-old man who presented with clinical features of G6PD deficiency-associated haemolysis and was found to have severe methaemoglobinaemia (35%). He was administered blood transfusions and intravenous ascorbic acid. His methaemoglobinaemia resolved within 24 hours. This case demonstrates the successful management of a patient with severe methaemoglobinaemia in the setting of G6PD deficiency haemolysis. Emergency physicians should be aware of the possible co-occurrence of severe methaemoglobinaemia in a patient with G6PD deficiency haemolysis. PMID- 29592990 TI - Management of a rhegmatogenous retinal detachment in a low-resource setting: treatment options when there is no vitreoretinal surgeon. AB - We discuss the case of a 49-year-old soldier with a macula-on rhegmatogenous retinal detachment in Sierra Leone. The case highlights the challenge of accessing visually preserving ophthalmic specialist care in sub-Saharan Africa (SSA) for vitreoretinal (VR) disease. It highlights a shortage of VR surgeons in SSA, limited examination facilities, the larger issue of accessing specialist care urgently and the costs associated with accessing surgery out-of-country. It also identifies a shortage in epidemiological data on the issue which limits the assessment of the scale of the problem. PMID- 29592991 TI - De Garengeot's hernia: a rare presentation of the wandering appendix. AB - A hernia is defined as a protrusion of an organ or its fascia through a sac of its containing cavity. The presentation of an inflamed appendix inside an incarcerated femoral hernia is termed de Garengeot's hernia. Almost exclusively seen in the female patient, this type of hernia like all others can undergo strangulation leading to complications including appendicitis with or without perforation. Management as described in literature usually comprises open or laparoscopic approach, followed by appendectomy and repair of the femoral hernia with or without mesh. We describe a case of a female patient who presented with an irreducible groin swelling, found to have a femoral hernia containing the inflamed appendix intraoperatively and how it was managed surgically through a laparoscopic approach with a small mesh and closure of defect. Literature review on this rare form of hernia is discussed thereafter. PMID- 29592992 TI - Aural foreign body in situ for 9 years mimicking impacted wax. PMID- 29592993 TI - Systemic inflammatory response in a liver transplant recipient: a potential side effect of mycophenolate mofetil. AB - Mycophenolate mofetil is a commonly used immunosuppressive medication in the postliver transplant setting where gastrointestinal side effects tend to predominate. However, in more recent times, emerging and rare side effects are being reported in the literature. We present a case of a patient who had a significant inflammatory response and associated marked weight loss with the uptitration in dose of mycophenolate mofetil. Extensive investigations were performed to exclude other infective, inflammatory or malignant aetiologies for these symptoms, however no other cause was identified. The patient had the medication ceased and subsequently had a dramatic improvement in his inflammatory markers and regained the weight lost while on the medication. PMID- 29592994 TI - Rare case of cystic artery pseudoaneurysm. AB - A patient with a cystic artery pseudoaneurysm (CAP) presented to the emergency department with upper abdominal and back pain. The patient also had clinical signs of sepsis. CT revealed gallstones with acute suppurative cholecystitis with a gallbladder perforation. In addition, a CAP was also suspected and subsequently diagnosed on CT angiography. The pseudoaneurysm was treated with embolisation and a cholecystostomy was performed for the gallbladder perforation. Following her acute admission, the patient underwent an elective cholecystectomy and made a good recovery post surgery. PMID- 29592995 TI - A rare case of pyogenic pericarditis secondary to Streptococcus constellatus. AB - We report an extremely rare case of purulent pericarditis caused by the normally commensal oral flora, Streptococcus constellatus, a viridans Streptococcal species and member of the S. anginosus group (previously also known by the eponymous 'S. milleri', for American Willoughby Dayton Miller). This case is a previously healthy 71-year-old immunocompetent woman from Arizona who presented with a 5-day history of progressive shortness of breath and chest tightness, and subjective fever and chills, but without history of nausea, vomiting, night sweats, recent travel, autoimmune disease or sick contacts. Early recognition and intervention of purulent pericarditis allow patients like the one outlined in this case to achieve full recovery. PMID- 29592996 TI - Trauma-induced adiposis dolorosa (Dercum's disease). AB - We present a case of a 39-year-old man who presented with chronic bilateral upper extremity pain associated with innumerable angiomyolipomas that developed 5 years after a motor vehicle accident involving his upper extremities. Our case notes the rare nature of painful adipose tissue deposits and the diagnostic challenges. PMID- 29592997 TI - Cornual ectopic pregnancy: laparoscopic management step by step. AB - Cornual (interstitial) ectopic pregnancy is an uncommon type of ectopic pregnancy which is located in the interstitial part of the fallopian tube. It accounts for 2%-4% of all ectopic pregnancies. Cornual pregnancies often pose a diagnostic and therapeutic challenge with a significant high morbidity and mortality as a result of massive intraperitoneal bleeding. A case of unruptured cornual ectopic pregnancy in a patient with abnormal uterine bleeding is reported which was successfully managed laparoscopically. PMID- 29592998 TI - Gestational gigantomastia with spontaneous resolution in an Indian woman. AB - We present the case of a 20-year-old woman, primigravida with 24 weeks of amenorrhoea due to pregnancy. She came with symptoms of rapidly increasing size of both the breasts since 8 weeks. On examination, both breasts were grossly enlarged, right more than left, with the level of the nipples reaching beyond the level of the umbilicus. Breast circumference was measured to be 72 cm on the right, and left breast was 66 cm. No palpable lumps in both breasts. No axillary lymphadenopathy noted. Hormonal studies were found to be within the normal range. The pregnancy was terminated due to pre-eclampsia. The patient opted for regular follow-up and observation. While regularly following up, the size of both breasts was observed to gradually reduce to a circumference of 40 cm on the right and 30 cm on the left. PMID- 29592999 TI - Treatment of refractory rheumatoid pleural effusion with abatacept. AB - Rheumatoid pleural effusion is generally responsive to corticosteroids, but refractory cases require consideration of second-line therapy. Here we report the case of a 61-year-old man with rheumatoid arthritis (RA) who developed a large right-sided pleural effusion and was successfully treated with abatacept. Thoracocentesis showed a sterile exudate and an elevated adenosine deaminase level. The methotrexate and etanercept used to treat the RA were withheld initially while he underwent a trial of prednisolone 40 mg/day for the pleural effusion. However, the effusion did not respond to this therapy. Thoracoscopic biopsy of the right pleura revealed fibrotic changes with lymphocyte infiltration mainly composed of CD4+ T cells and B cells but no evidence of malignancy or infection. The patient was started on abatacept and resumed methotrexate. The treatment was effective in our case. Abatacept should be considered as a treatment option in patients with refractory rheumatoid pleural effusion.

PMID- 29593000 TI - Diagnostic dilemma: think about anterior cutaneous nerve entrapment syndrome (ACNES) in patients with atypical abdominal pain and Crohn's disease. AB - Chronic abdominal pain can be a difficult diagnostic dilemma. Anterior cutaneous nerve entrapment syndrome (ACNES) is a potential differential diagnosis that should be considered because treatment is both easy and effective. We describe the case of a 51-year-old man presenting with 7 months of right lower quadrant abdominal pain on the background of known Crohn's disease. A circumspect surgical approach and multidisciplinary input was key to making the diagnosis of a nerve entrapment syndrome. PMID- 29593002 TI - Angioedema as the presenting feature of systemic lupus erythematosus. AB - A young female in her early 20s presented with low-grade fever for 1 month, puffiness of face and abdominal distension for 15 days. Evaluation revealed pancytopenia with normocellular marrow, hypocomplementaemia and Coomb's positive haemolytic anaemia. She had angioedema with laryngospasm and worsening facial oedema which had dramatic response to steroids. Further workup lead to a diagnosis of systemic lupus erythematosus with neuropsychiatric involvement. Treatment with pulse steroids and cyclophosphamide resulted in dramatic improvement of her symptoms with no recurrence of angioedema during her follow-up visits. PMID- 29593003 TI - Intraosseous ganglion cyst of the distal tibia: a rare entity in a rarer location. AB - Intraosseous ganglion cysts are rare entities, even rarer in the subchondral region of the distal tibia. A 20-year-old male presented to us with complaints of pain and limp in the right ankle joint, which was diagnosed as an intraosseous ganglion cyst of the right distal tibia and was successfully treated with curettage and bone cement with no recurrence seen even after a year. PMID- 29593004 TI - Giant coronary artery aneurysms in a 12-week-old infant with incomplete Kawasaki disease. AB - Kawasaki disease (KD) is an acute inflammatory vasculitis that occurs worldwide and disproportionately affects male children, most commonly between the ages of 6 months and 5 years. KD can present with only a few features and thus be difficult to diagnose, particularly in the youngest and oldest patients. We describe a 12 week-old Caucasian female infant who presented with rash and fever but no other features of KD, who developed giant coronary artery aneurysms. Considering how common is the presentation of a febrile infant with a rash, this case highlights the importance of considering KD early in the differential diagnosis for any infant with unexplained fever. Furthermore, it emphasises how echocardiography can help in the investigation of a febrile child with no clear source of infection.

PMID- 29593010 TI - Differences in Breast Cancer Survival by Molecular Subtypes in the United States. AB - : Background: Although incidence rates of breast cancer molecular subtypes are well documented, effects of molecular subtypes on breast cancer-specific survival using the largest population coverage to date are unknown in the U.S. POPULATION: Methods: Using Surveillance, Epidemiology and End Results cancer registry data, we assessed survival after breast cancer diagnosis among women diagnosed during 2010 to 2013 and followed through December 31, 2014. Breast cancer molecular subtypes defined by joint hormone receptor [HR, estrogen receptor (ER) and/or progesterone receptor (PR)] and HER2 status were assessed. Multiple imputation was used to fill in missing receptor status. Four-year breast cancer-specific survival per molecular subtypes and clinical/demographic factors were calculated. A Cox proportional hazards model was used to evaluate survival while controlling for clinical and demographic factors.Results: The best survival pattern was observed among women with HR+/HER2- subtype (survival rate of 92.5% at 4 years), followed by HR+/HER2+ (90.3%), HR-/HER2+ (82.7%), and finally worst survival for triple-negative subtype (77.0%). Notably, failing to impute cases with missing receptor status leads to overestimation of survival because those with missing receptor status tend to have worse prognostic features. Survival differed substantially by stage at diagnosis. Among de novo stage IV disease, women with HR+/HER2+ subtype experienced better survival than those with HR+/HER2- subtype (45.5% vs. 35.9%), even after controlling for other factors.Conclusions: Divergence of survival curves in stage IV HR+/HER2+ versus HR+/HER2- subtype is likely attributable to major advances in HER2-targeted treatment.Impact: Contrary to conventional thought, HR+/HER2+ subtype experienced better survival than HR+/HER2- in advanced-stage disease.

AB - Background: Expression of human paracrine hormones stanniocalcin 1 (STC1) and stanniocalcin 2 (STC2) may potentiate late breast cancer recurrence. We tested the hypothesis that expression of STC1 and STC2 in primary breast tumors is more strongly associated with late versus early recurrences.Methods: A total of 541 estrogen receptor-positive, tamoxifen-treated (ER+/TAM+) and 300 ER-negative, tamoxifen-untreated (ER-/TAM-) breast cancer patients who experienced recurrence within 10 years of primary diagnosis and matched recurrence-free controls were selected from a cohort of 11,251 Danish breast cancer patients diagnosed with stage I, II, or III breast cancer during 1985 to 2001. The association between IHC expression of STC1 and STC2 in primary breast tumor tissue microarrays and breast cancer recurrence was evaluated within median time to recurrence quintiles.Results: The association between STC1 expression, dichotomized as positive or negative, and recurrence was strongly positive for the final time quintile (6-10 years postdiagnosis) in the ER+/TAM+ group [aOR = 2.70; 95% confidence interval (CI): 1.22-5.98]. Regression of the log ORs relating dichotomous STC1 and STC2 expression to recurrence by median time to recurrence (year) resulted in a relatively large positive effect estimate for STC1 (beta = 0.16; 95% CI, -0.03-0.36) and a near-null positive effect estimate for STC2 (beta = 0.04; 95% CI, -0.14-0.21).Conclusions: Our results suggest a stronger association between primary tumor STC1 expression and late recurrence, as opposed to early recurrence, although no clear trend was apparent.Impact: STC1 expression in the primary tumor may potentiate late recurrences, suggesting dormancy pathways that merit further investigation.

PMID- 29593011 TI - Rural Disparities in Treatment-Related Financial Hardship and Adherence to Surveillance Colonoscopy in Diverse Colorectal Cancer Survivors. AB - Background: Cancer survivors increasingly report financial hardship as a consequence of the high cost of cancer care, yet the financial experience of rural cancer survivors remains largely unstudied. The purpose of this study was to investigate potential rural disparities in the likelihood of financial hardship and nonadherence to surveillance colonoscopy.Methods: Individuals diagnosed with localized or regional colorectal cancer between 2004 and 2012 were ascertained by the population-based New Mexico Tumor Registry. Participants completed a mailed questionnaire or telephone survey about their colorectal cancer survivorship experience, including treatment-related financial hardship and receipt of surveillance colonoscopy. Multivariable logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs).Results: Compared with urban colorectal cancer survivors (n = 168), rural colorectal cancer survivors (n = 109) were slightly older; more likely to be married (65% vs. 59%) and have an annual income <$30,000 (37% vs. 27%); and less likely to be employed (35% vs. 41%), have a college degree (28% vs. 38%), or a high level of health literacy (39% vs. 51%). Rural survivors were twice as likely as urban survivors to report treatment-related financial hardship (OR, 1.86; 95% CI, 1.06-3.28) and nonadherence to surveillance colonoscopy guidelines (OR, 2.28; 95% CI, 1.07-4.85). In addition, financial hardship was independently associated with nonadherence to surveillance colonoscopy (OR, 2.17; 95% CI, 1.01 4.85).Conclusions: Substantial rural disparities in the likelihood of financial hardship and nonadherence to surveillance colonoscopy exist.Impact: Treatment related financial hardship among rural colorectal cancer survivors may negatively affect adherence to guideline-recommended follow-up care.

PMID- 29593012 TI - Demand for Colonoscopy in Colorectal Cancer Screening Using a Quantitative Fecal Immunochemical Test and Age/Sex-Specific Thresholds for Test Positivity. AB - Background: Despite age and sex differences in fecal hemoglobin (f-Hb) concentrations, most fecal immunochemical test (FIT) screening programs use population-average cut-points for test positivity. The impact of age/sex-specific threshold on FIT accuracy and colonoscopy demand for colorectal cancer screening are unknown.Methods: Using data from 723,113 participants enrolled in a Taiwanese population-based colorectal cancer screening with single FIT between 2004 and 2009, sensitivity and specificity were estimated for various f-Hb thresholds for test positivity. This included estimates based on a "universal" threshold, receiver-operating-characteristic curve-derived threshold, targeted sensitivity, targeted false-positive rate, and a colonoscopy-capacity-adjusted method integrating colonoscopy workload with and without age/sex adjustments.Results: Optimal age/sex-specific thresholds were found to be equal to or lower than the universal 20 MUg Hb/g threshold. For older males, a higher threshold (24 MUg Hb/g) was identified using a 5% false-positive rate. Importantly, a nonlinear relationship was observed between sensitivity and colonoscopy workload with workload rising disproportionately to sensitivity at 16 MUg Hb/g. At this "colonoscopy-capacity-adjusted" threshold, the test positivity (colonoscopy workload) was 4.67% and sensitivity was 79.5%, compared with a lower 4.0% workload and a lower 78.7% sensitivity using 20 MUg Hb/g. When constrained on capacity, age/sex-adjusted estimates were generally lower. However, optimizing age/-sex-adjusted thresholds increased colonoscopy demand across models by 17% or greater compared with a universal threshold.Conclusions: Age/sex-specific thresholds improve FIT accuracy with modest increases in colonoscopy demand.Impact: Colonoscopy-capacity-adjusted and age/sex-specific f-Hb thresholds may be useful in optimizing individual screening programs based on detection accuracy, population characteristics, and clinical capacity.

AB - BACKGROUND: Familial hypercholesterolemia (FH) is a condition with very high concentrations of low-density lipoprotein (LDL) cholesterol and high risk of ischemic heart disease including myocardial infarction. However, there is limited and contradictory information on whether FH and high LDL cholesterol per se confer high risk of ischemic stroke. We tested the hypotheses that individuals in the general population with FH and/or high LDL cholesterol have higher risk of ischemic stroke. METHODS: The associations of FH and high LDL cholesterol with ischemic stroke risk were tested in both causal, genetic, and observational analyses using 106 412 individuals from the CGPS (Copenhagen General Population Study; 2823 ischemic strokes and 3792 myocardial infarctions) and/or 10 372 individuals from the CCHS (Copenhagen City Heart Study; 945 ischemic strokes and 1142 myocardial infarctions). FH causative mutations were LDLR W23X(rs267607213), W66G(rs121908025) and W556S, and APOB R3500Q(rs5742904). A Mendelian randomization design tested whether high LDL cholesterol per se has a causal effect on ischemic stroke risk, using a combination of the FH causative mutations and common genetic variants associated with high LDL cholesterol. RESULTS: The cumulative incidences in individuals in the CGPS with and without FH causative mutations were similar for ischemic stroke ( P=0.50) but not for myocardial infarction ( P<0.001): at age 80 years, 4% and 7% of these individuals developed ischemic stroke and 20% and 8% myocardial infarction, with similar results in the CCHS. There was no association between clinical FH and ischemic stroke, except if personal premature ischemic heart disease was included in the clinical FH criteria. Ischemic heart disease at baseline was associated with higher ischemic stroke risk, explaining the higher ischemic stroke risk in those with high LDL cholesterol. For a 1 mmol/L higher LDL cholesterol, the genetic causal risk ratio was 1.11 (0.62-2.02) for ischemic stroke and 1.45 (1.08-1.93) for myocardial infarction. CONCLUSIONS: FH and high LDL cholesterol did not confer an increased risk of ischemic stroke. A positive association with ischemic stroke observed for some clinical FH criteria and high LDL cholesterol appears to be due to previous ischemic heart disease, rather than to high LDL cholesterol per se. PMID- 29593014 TI - Ryanodine Receptor Calcium Leak in Circulating B-Lymphocytes as a Biomarker in Heart Failure. AB - BACKGROUND: Advances in congestive heart failure (CHF) management depend on biomarkers for monitoring disease progression and therapeutic response. During systole, intracellular Ca2+ is released from the sarcoplasmic reticulum into the cytoplasm through type-2 ryanodine receptor/Ca2+ release channels. In CHF, chronically elevated circulating catecholamine levels cause pathological remodeling of type-2 ryanodine receptor/Ca2+ release channels resulting in diastolic sarcoplasmic reticulum Ca2+ leak and decreased myocardial contractility. Similarly, skeletal muscle contraction requires sarcoplasmic reticulum Ca2+ release through type-1 ryanodine receptors (RyR1), and chronically elevated catecholamine levels in CHF cause RyR1-mediated sarcoplasmic reticulum Ca2+ leak, contributing to myopathy and weakness. Circulating B-lymphocytes express RyR1 and catecholamine-responsive signaling cascades, making them a potential surrogate for defects in intracellular Ca2+ handling because of leaky RyR channels in CHF. METHODS: Whole blood was collected from patients with CHF, CHF following left-ventricular assist device implant, and controls. Blood was also collected from mice with ischemic CHF, ischemic CHF+S107 (a drug that specifically reduces RyR channel Ca2+ leak), and wild-type controls. Channel macromolecular complex was assessed by immunostaining RyR1 immunoprecipitated from lymphocyte-enriched preparations. RyR1 Ca2+ leak was assessed using flow cytometry to measure Ca2+ fluorescence in B-lymphocytes in the absence and presence of RyR1 agonists that empty RyR1 Ca2+ stores within the endoplasmic reticulum. RESULTS: Circulating B-lymphocytes from humans and mice with CHF exhibited remodeled RyR1 and decreased endoplasmic reticulum Ca2+ stores, consistent with chronic intracellular Ca2+ leak. This Ca2+ leak correlated with circulating catecholamine levels. The intracellular Ca2+ leak was significantly reduced in mice treated with the Rycal S107. Patients with CHF treated with left ventricular assist devices exhibited a heterogeneous response. CONCLUSIONS: In CHF, B-lymphocytes exhibit remodeled leaky RyR1 channels and decreased endoplasmic reticulum Ca2+ stores consistent with chronic intracellular Ca2+ leak. RyR1-mediated Ca2+ leak in B-lymphocytes assessed using flow cytometry provides a surrogate measure of intracellular Ca2+ handling and systemic sympathetic burden, presenting a novel biomarker for monitoring response to pharmacological and mechanical CHF therapy. PMID- 29593015 TI - An APOO Pseudogene on Chromosome 5q Is Associated With Low-Density Lipoprotein Cholesterol Levels. AB - BACKGROUND: Elevated levels of low-density lipoprotein cholesterol (LDL-C) are a major risk factor for cardiovascular disease via its contribution to the development and progression of atherosclerotic lesions. Although the genetic basis of LDL-C has been studied extensively, currently known genetic variants account for only ~20% of the variation in LDL-C levels. METHODS: Through an array based association analysis in 1102 Amish subjects, we identified a variant strongly associated with LDL-C levels. Using a combination of genetic analyses, zebrafish models, and in vitro experiments, we sought to identify the causal gene driving this association. RESULTS: We identified a founder haplotype associated with a 15 mg/dL increase in LDL-C on chromosome 5. After recombination mapping, the associated region contained 8 candidate genes. Using a zebrafish model to evaluate the relevance of these genes to cholesterol metabolism, we found that expression of the transcribed pseudogene, APOOP1, increased LDL-C and vascular plaque formation. CONCLUSIONS: Based on these data, we propose that APOOP1 regulates levels of LDL-C in humans, thus identifying a novel mechanism of lipid homeostasis. PMID- 29593016 TI - GCAT|Genomes for life: a prospective cohort study of the genomes of Catalonia. AB - PURPOSE: The prevalence of chronic non-communicable diseases (NCDs) is increasing worldwide. NCDs are the leading cause of both morbidity and mortality, and it is estimated that by 2030, they will be responsible for 80% of deaths across the world. The Genomes for Life (GCAT) project is a long-term prospective cohort study that was designed to integrate and assess the role of epidemiological, genomic and epigenomic factors in the development of major chronic diseases in Catalonia, a north-east region of Spain. PARTICIPANTS: At the end of 2017, the GCAT Study will have recruited 20 000 participants aged 40-65 years. Participants who agreed to take part in the study completed a self-administered computer driven questionnaire, and underwent blood pressure, cardiac frequency and anthropometry measurements. For each participant, blood plasma, blood serum and white blood cells are collected at baseline. The GCAT Study has access to the electronic health records of the Catalan Public Healthcare System. Participants will be followed biannually at least 20 years after recruitment. FINDINGS TO DATE: Among all GCAT participants, 59.2% are women and 83.3% of the cohort identified themselves as Caucasian/white. More than half of the participants have higher education levels, 72.2% are current workers and 42.1% are classified as overweight (body mass index >=25 and <30 kg/m2). We have genotyped 5459 participants, of which 5000 have metabolome data. Further, the whole genome of 808 participants will be sequenced by the end of 2017. FUTURE PLANS: The first follow-up study started in December 2017 and will end by March 2018. Residences of all subjects will be geocoded during the following year. Several genomic analyses are ongoing, and metabolomic and genomic integrations will be performed to identify underlying genetic variants, as well as environmental factors that influence metabolites. PMID- 29593017 TI - Electroacupuncture plus standard of care for managing refractory functional dyspepsia: protocol of a pragmatic trial with economic evaluation. AB - INTRODUCTION: This trial proposes to compare the effectiveness and cost effectiveness of electroacupuncture (EA) plus on-demand gastrocaine with waiting list for EA plus on-demand gastrocaine in providing symptom relief and quality-of life improvement among patients with functional dyspepsia (FD). METHODS AND ANALYSIS: This is a single-centre, pragmatic, randomised parallel-group, superiority trial comparing the outcomes of (1) EA plus on-demand gastrocaine group and (2) waiting list to EA plus on-demand gastrocaine group. 132 (66/arm) endoscopically confirmed, Helicobacter pylori-negative patients with FD will be recruited. Enrolled patients will respectively be receiving (1) 20 sessions of EA over 10 weeks plus on-demand gastrocaine; or (2) on-demand gastrocaine and being nominated on to a waiting list for EA, which entitles them 20 sessions of EA over 10 weeks after 12 weeks of waiting. The primary outcome will be the between-group difference in proportion of patients achieving adequate relief of symptoms over 12 weeks. The secondary outcomes will include patient-reported change in global symptoms and individual symptoms, Nepean Dyspepsia Index, Nutrient Drink Test, 9 item Patient Health Questionnaire (PHQ9), and 7-item Generalised Anxiety Disorder Scale (GAD7). Adverse events will be assessed formally. Results on direct medical costs and on the EuroQol (EQ-5D) questionnaire will also be used to assess cost effectiveness. Analysis will follow the intention-to-treat principle using appropriate univariate and multivariate methods. A mixed model analysis taking into account missing data of these outcomes will be performed. Cost-effectiveness analysis will be performed using established approach. ETHICS AND DISSEMINATION: The study is supported by the Health and Medical Research Fund, Government of the Hong Kong Special Administrative Region of China. It has been approved by the Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee. Results will be published in peer-reviewed journals and be disseminated in international conference. TRIAL REGISTRATION NUMBER: ChiCTR-IPC-15007109; Pre-result. PMID- 29593018 TI - Randomised controlled trial of rhinothermy for treatment of the common cold: a feasibility study. AB - OBJECTIVE: To determine the feasibility of a randomised controlled trial (RCT) of rhinothermy for the common cold. DESIGN: Open label, randomised, controlled feasibility study. SETTING: Single-centre research institute in New Zealand recruiting participants from the community. PARTICIPANTS: 30 adult participants with symptoms of a common cold, presenting within 48 hours of the onset of symptoms. INTERVENTIONS: Participants were randomly assigned 2:1 to receive either 35 L/min of 100% humidified air at 41 degrees C via high flow nasal cannulae, 2 hours per day for up to 5 days (rhinothermy), or vitamin C 250 mg daily for 5 days (control). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the proportion of screened candidates who were randomised. Secondary outcomes included: proportion of randomised participants who completed the study; modified Jackson scores from randomisation to 10 days after initiation of randomised regimen; time until feeling 'a lot better' compared with study entry; time until resolution of symptoms or symptom score at 10 days postrandomisation; proportion of organisms identified by PCR analysis of nasal swabs taken at baseline; the patterns of use of the rhinothermy device; estimated adherence of the control group; and rhinothermy device tolerability. RESULTS: In all 30/79 (38%, 95% CI 27% to 50%) of potential participants screened for eligibility were randomised. Rhinothermy was well tolerated, and all randomised participants completed the study (100%, 95% CI 88% to 100%). The reduction from baseline in the modified Jackson score was greater with rhinothermy compared with control at days 2, 3, 4, 5 and 6, with the maximum difference at day 4 (-6.4, 95% CI -9.4 to -3.3). The substantial clinical benefit threshold for modified Jackson score was a 5-unit change. CONCLUSIONS: This study shows that an RCT of rhinothermy compared with low-dose vitamin C in the treatment of the common cold is feasible. TRIAL REGISTRATION NUMBER: ACTRN12616000470493; Results. PMID- 29593019 TI - Recruitment for exercise or physical activity interventions: a protocol for systematic review. AB - INTRODUCTION: Recruiting participants into research trials is essential for the advancement of scientific knowledge that depends on clinical research studies. For the field of exercise and physical activity, there is an added difficulty in recruiting participants because participants must be willing to participate in an intervention that requires a significant commitment of both time and physical effort. Therefore, we have planned a systematic review to analyse how methodological factors, intervention characteristics and participant demographics impact recruitment rates in specific populations. This information will help researchers improve the design and recruitment approach in future studies. METHODS AND ANALYSIS: A mixed methods systematic review will be performed on studies that implement physical activity interventions and present data on participant recruitment. We plan on searching the Pubmed, Cumulative Index to Nursing and Allied Health Literature and Online Resource for Recruitment research in Clinical Trials databases for potentially eligible articles from database inception through 10 February 2017. A standardised approach will be used to identify studies through a review of titles, abstracts and reference lists. The process for each eligible study is to determine their eligibility, extract data from eligible studies and rate each eligible study's methodological quality. Exploratory multivariate regression models will be used to determine the effects of methodological factors, intervention characteristics and participant demographics on the recruitment variables of interest. ETHICS AND DISSEMINATION: Because all of the data used in this systematic review has been published, this review does not require ethical approval. The results of this review will be disseminated through peer-reviewed publication as well as through conference presentations. PROSPERO REGISTRATION NUMBER: CRD42017057284. PMID- 29593020 TI - Ethnic differences in the progression of chronic kidney disease and risk of death in a UK diabetic population: an observational cohort study. AB - OBJECTIVE: To determine ethnic differences in the progression of chronic kidney disease (CKD) and risk of end-stage renal failure (ESRF) and death in adults with type 2 diabetes mellitus (T2DM), and to identify predictors of rapid renal decline. DESIGN: Observational community-based cohort study undertaken from 2006 to 2016 with nested case-control study. SETTING: 135 inner London primary care practices contributing to the east London Database. PARTICIPANTS: General practice-registered adults aged 25-85 years with established T2DM and CKD at baseline. OUTCOMES: The annual rate of renal decline was compared between white, south Asian and black groups, and stratified by proteinuria and raised blood pressure (BP) at baseline. Predictors of rapid renal decline were identified in a nested case-control study. Cox proportional hazards regression was used to determine ethnic differences in the risk of ESRF and death. RESULTS: Age-sex adjusted annual decline was greatest in the Bangladeshi population. There was stepwise increase in the rate of decline when stratifying the cohort by baseline proteinuria and BP control, with south Asian groups being most sensitive to the combined effect of proteinuria and raised BP after accounting for key confounders.The odds of rapid renal decline were increased for individuals of Bangladeshi, African and Caribbean ethnicity, those with hypertension, proteinuria, cardiovascular disease and with increasing duration of diabetes. Rapid progression was more frequent in younger age groups. Risk of developing ESRF was highest in the black group compared with the white group (HR 1.88, 95% CI 1.11 to 3.19). Risk of death from any cause was 29% lower in the south Asian group compared with the white group (HR 0.71, 95% CI 0.56 to 0.91). CONCLUSIONS: Proteinuria and hypertension trigger accelerated estimated glomerular filtration rate decline differentially by ethnicity. Active monitoring of younger adults, who have greater odds of rapid progression and the most to gain from interventions, is essential. PMID- 29593021 TI - Lifestyle advice to cancer survivors: a qualitative study on the perspectives of health professionals. AB - OBJECTIVES: Adoption of healthy lifestyle behaviours has shown promising effectiveness in reducing the high morbidity burden of cancer survivors. Health professionals (HPs) are well suited to provide lifestyle advice but few survivors report receiving guidance from them. This study aimed to explore HPs' perspective of lifestyle advice (on healthy eating, physical activity, smoking, and alcohol) for cancer survivors. DESIGN: In-depth semistructured qualitative interviews were conducted by telephone or face to face. Data were analysed using qualitative content analysis. SETTING AND PARTICIPANTS: Twenty-one UK HPs working in secondary care with breast, prostate or colorectal cancer survivors were interviewed. RESULTS: The overarching theme was that HPs' desire to provide lifestyle advice was not necessarily matched by knowledge and action. Three main themes were identified: (1) survivorship-centred barriers to provision, (2) HP centred barriers to provision, and (3) optimal delivery of lifestyle advice. Results suggested that HPs' perceptions of survivors' current status of practising health behaviours, their perceived socioeconomic barriers and ability to practise health behaviours, and HPs' fear for potential loss of connection with the patient influenced provision of lifestyle advice. Further factors included HPs' knowledge of healthy lifestyle guidelines, feeling that they were not the 'right person' to provide advice, and lack of time and resources. HPs stressed that the optimal delivery of lifestyle advice should (1) be tailored to the individual and delivered throughout the cancer journey, (2) be focused on small and achievable changes framed as part of their treatment regimen and (3) be cost-effective for wide-scale implementation. CONCLUSIONS: Incorporation of the identified barriers when developing HP training programmes and lifestyle interventions could increase the probability of successful behavioural change, and thus improve outcomes for cancer survivors. PMID- 29593022 TI - Hospital at Home care for older patients with cognitive impairment: a protocol for a randomised controlled feasibility trial. AB - INTRODUCTION: An acute hospital admission is a stressful life event for older people, particularly for those with cognitive impairment. The hospitalisation is often complicated by hospital-associated geriatric syndromes, including delirium and functional loss, leading to functional decline and nursing home admission. Hospital at Home care aims to avoid hospitalisation-associated adverse outcomes in older patients with cognitive impairment by providing hospital care in the patient's own environment. METHODS AND ANALYSIS: This randomised, non-blinded feasibility trial aims to assess the feasibility of conducting a randomised controlled trial in terms of the recruitment, use and acceptability of Hospital at Home care for older patients with cognitive impairment. The quality of care will be evaluated and the advantages and disadvantages of the Hospital at Home care programme compared with usual hospital care. Eligible patients will be randomised either to Hospital at Home care in their own environment or usual hospital care. The intervention consists of hospital level care provided at patients' homes, including visits from healthcare professionals, diagnostics (laboratory tests, blood cultures) and treatment. The control group will receive usual hospital care. Measurements will be conducted at baseline, during admission, at discharge and at 3 and 6 months after the baseline assessment. ETHICS AND DISSEMINATION: Institutional ethics approval has been granted. The findings will be disseminated through public lectures, professional and scientific conferences, as well as peer-reviewed journal articles. The study findings will contribute to knowledge on the implementation of Hospital at Home care for older patients with cognitive disorders. The results will be used to inform and support strategies to deliver eligible care to older patients with cognitive impairment. TRIAL REGISTRATION NUMBER: e020313; Pre-results. PMID- 29593023 TI - Migraine and the risk of cardiovascular and cerebrovascular events: a meta analysis of 16 cohort studies including 1 152 407 subjects. AB - OBJECTIVES: To perform an updated meta-analysis to evaluate the long-term cardiovascular and cerebrovascular outcomes among migraineurs. SETTING: A meta analysis of cohort studies performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SOURCES: The MEDLINE, Web of Science and Cochrane Central Register of Controlled Trials databases were searched for relevant articles. PARTICIPANTS: A total of 16 cohort studies (18 study records) with 394 942 migraineurs and 757 465 non-migraineurs were analysed. PRIMARY AND SECONDARY OUTCOME MEASURES: Major adverse cardiovascular and cerebrovascular events (MACCE), stroke (ie, ischaemic, haemorrhagic or non specified), myocardial infarction (MI) and all-cause mortality. The outcomes were reported at the longest available follow-up. DATA ANALYSIS: Summary-adjusted hazard ratios (HR) were calculated by random-effects Der-Simonian and Liard model. The risk of bias was assessed by the Newcastle-Ottawa Scale. RESULTS: Migraine was associated with a higher risk of MACCE (adjusted HR 1.42, 95% confidence interval [CI] 1.26 to 1.60, P<0.001, I2=40%) driven by a higher risk of stroke (adjusted HR 1.41, 95% CI 1.25 to 1.61, P<0.001, I2=72%) and MI (adjusted HR 1.23, 95% CI 1.03 to 1.43, P=0.006, I2=59%). There was no difference in the risk of all-cause mortality (adjusted HR 0.93, 95% CI 0.78 to 1.10, P=0.38, I2=91%), with a considerable degree of statistical heterogeneity between the studies. The presence of aura was an effect modifier for stroke (adjusted HR aura 1.56, 95% CI 1.30 to 1.87 vs adjusted HR no aura 1.11, 95% CI 0.94 to 1.31, P interaction=0.01) and all-cause mortality (adjusted HR aura 1.20, 95% CI 1.12 to 1.30 vs adjusted HR no aura 0.96, 95% CI 0.86 to 1.07, Pinteraction<0.001). CONCLUSION: Migraine headache was associated with an increased long-term risk of cardiovascular and cerebrovascular events. This effect was due to an increased risk of stroke (both ischaemic and haemorrhagic) and MI. There was a moderate to severe degree of heterogeneity for the outcomes, which was partly explained by the presence of aura. PROSPERO REGISTRATION NUMBER: CRD42016052460. PMID- 29593024 TI - Feasibility of Improving Cerebral Autoregulation in Acute Intracerebral Haemorrhage (BREATHE-ICH) study: a protocol for an experimental interventional study. AB - INTRODUCTION: Cerebral autoregulation (CA) is impaired in a multitude of neurological conditions. Increasingly, clinical studies are correlating the nature of this impairment with prognostic markers. In acute intracerebral haemorrhage (ICH), impairment of CA has been associated with worsening clinical outcomes including poorer Glasgow Coma Score and larger haematoma volume. Hypocapnia has been shown to improve CA despite concerns over hypoperfusion and consequent ischaemic risks, and it is therefore hypothesised that hypocapnia (via hyperventilation) in acute ICH may improve CA and consequently clinical outcome. BREATHE-ICH is a CA-targeted interventional study in acute ICH utilising a simple bedside hyperventilatory manoeuvre. METHODS AND ANALYSIS: Patients with acute ICH within 48 hours of onset will be included. The experimental set-up measures cerebral blood flow (cerebral blood velocity, transcranial Doppler), blood pressure (Finometer) and end tidal carbon dioxide (capnography) at baseline, and in response to hypocapnia (-5 mm and -10 mm Hg below baseline) achieved via a 90 s hyperventilatory manoeuvre. Autoregulation is evaluated with transfer function analysis and autoregulatory index calculations. Important classical endpoints associated with this before and after interventional study include death and disability at 14 days and the proportion of recruited individuals able to comply with the full measurement protocol. ETHICS AND DISSEMINATION: A favourable opinion was granted by the East Midlands-Nottingham 1 Research Ethics Committee (17/EM/0283). It is anticipated that the results of this study will be presented at national and international meetings, with reports being published in journals during late 2018.

The Paris Prospective Study III. AB - OBJECTIVES: Excessive daytime sleepiness (EDS) is a common sleep complaint in the population and is increasingly recognised as deleterious for health. Simple and sensitive tools allowing identifying individuals at greater risk of EDS would be of public health importance. Hence, we determined trajectories of body silhouette from early childhood to adulthood and evaluated their association with EDS in adulthood. DESIGN: A retrospective analysis in a prospective community-based study. PARTICIPANTS: 6820 men and women self-reported their silhouette at ages 8, 15, 25, 35 and 45 using the body silhouettes proposed by Stunkard et al. EDS was defined by an Epworth Sleepiness Scale score >=11. MAIN OUTCOME MEASURE: Presence of EDS in adulthood. RESULTS: The study population comprised 6820 participants (mean age 59.8 years, 61.1% men). Five distinct body silhouettes trajectories over the lifespan were identified: 31.9% 'lean stable', 11.1% 'lean increase', 16.1% 'lean-marked increase', 32.5% 'moderate stable' and 8.4% 'heavy stable'. Subjects with a 'heavy-stable' trajectory (OR 1.24, 95% CI 0.94 to 1.62) and those with a 'lean-marked increase' trajectory (OR 1.46, 95% CI 1.18 to 1.81) were more likely to have EDS when compared with the 'lean-stable' group after adjusting for confounding. Further adjustment for birth weight strengthened the magnitude of the ORs. CONCLUSION: Increasing body silhouette and to a lesser extent constantly high body silhouette trajectory from childhood to adulthood are associated with increased likelihood of EDS, independently of major confounding variables.

PMID- 29593026 TI - Impacts of smoke-free public places legislation on inequalities in youth smoking uptake: study protocol for a secondary analysis of UK survey data. AB - INTRODUCTION: Smoke-free public places legislation has been introduced in many countries to protect the public from the harmful effects of secondhand smoking. While evaluations of smoke-free policies have demonstrated major public health benefits, the impact on youth smoking and inequalities in smoking remains unclear. This project aims to evaluate how smoke-free public places legislation in the UK has impacted on inequalities in youth smoking uptake, and how much of any impact is via changes in parental smoking behaviour. METHODS AND ANALYSIS: The study will constitute secondary analyses of UK data (from the British Household Panel Survey and the Understanding Society study). Merging these datasets gives coverage of the period from 1994 to 2016. Missing data will be handled using multiple imputation. The primary outcomes are the rates and inequalities in initiation, experimentation, escalation to daily smoking and quitting among youths aged 11-15 years. Secondary outcomes include the prevalence of smoking among parents of these youths. Discrete-time event history analysis will be conducted to examine whether changes in the probability of youth smoking transitions are associated with the implementation of the smoke-free public places legislation; and whether any observed effects differ by socioeconomic position and parental smoking. A multilevel logistic regression model will be used to investigate whether there is a step change or change in trend for the prevalence of parental smoking after the policy was implemented. The models will be adjusted for relevant factors (including cigarette taxation, the change in the legal age for purchase of cigarettes and e-cigarette prevalence) that may be associated with the implementation of the legislation. ETHICS AND DISSEMINATION: This project will use anonymised survey data which have been collected following independent ethical review. The dissemination of the study findings will adopt multiple communication channels targeting both scientific and non-scientific audiences. PMID- 29593028 TI - 5-Fluorouracil Enhances Protoporphyrin IX Accumulation and Lesion Clearance during Photodynamic Therapy of Actinic Keratoses: A Mechanism-Based Clinical Trial. AB - Purpose: Actinic keratoses (AK) are precancerous lesions that can progress to squamous cell carcinoma. Photodynamic therapy (PDT) and topical 5-fluorouracil (5FU) are commonly used agents for AK. Empirical reports suggest that combining them can improve the therapeutic response. However, the optimal combined regimen was not clear in terms of proper sequence, timing, and mechanism. This clinical study explored mechanisms of action for neoadjuvantal 5FU and PDT for treatment of AK.Patients and Methods: A bilaterally controlled trial (17 patients) was performed. One side of the body (face, scalp, forearms) received 5FU pretreatment for 6 days, whereas the other side served as no-pretreatment control. Methylaminolevulinate cream was applied to both sides for 3 hours, and protoporphyrin IX (PpIX) levels were measured by noninvasive fluorimetry and skin biopsy. After red light illumination, lesion clearance was assessed at 3, 6, 9, and 12 months after PDT.Results: PpIX levels were increased 2- to 3-fold in 5FU pretreated lesions versus controls. Altered expression of heme-synthetic enzymes (coproporphyrinogen oxidase and ferrochelatase) and induction of p53 were observed, probably accounting for increased PpIX and subsequent cancer cell death. Relative clearance rates after PDT with or without 5FU pretreatment were 75% versus 45% at 3 months, and 67% versus 39% at 6 months, respectively; these differences were statistically significant.Conclusions: Serial 5FU and PDT improve AK clearance by at least two mechanisms, enhanced photosensitizer accumulation and p53 induction. Because 5FU and PDT are FDA-approved modalities, the combined regimen can be readily employed in clinical practice to reduce AK burden and reduce SCC risk. Clin Cancer Res; 24(13); 3026-35.

AB - A functional, replete T-cell repertoire is an integral component to adequate immune surveillance and to the initiation and maintenance of productive antitumor immune responses. Glioblastoma (GBM), however, is particularly adept at sabotaging antitumor immunity, eliciting severe T-cell dysfunction that is both qualitative and quantitative. Understanding and countering such dysfunction are among the keys to harnessing the otherwise stark potential of anticancer immune based therapies. Although T-cell dysfunction in GBM has been long described, newer immunologic frameworks now exist for reclassifying T-cell deficits in a manner that better permits their study and reversal. Herein, we divide and discuss the various T-cell deficits elicited by GBM within the context of the five relevant categories: senescence, tolerance, anergy, exhaustion, and ignorance. Categorization is appropriately made according to the molecular bases of dysfunction. Likewise, we review the mechanisms by which GBM elicits each mode of T-cell dysfunction and discuss the emerging immunotherapeutic strategies designed to overcome them.

AB - In nature, multiple adaptive phenotypes often coevolve and can be controlled by tightly linked genetic loci known as supergenes. Dissecting the genetic basis of these linked phenotypes is a major challenge in evolutionary genetics. Multiple freshwater populations of threespine stickleback fish (Gasterosteus aculeatus) have convergently evolved two constructive craniofacial traits, longer branchial bones and increased pharyngeal tooth number, likely as adaptations to dietary differences between marine and freshwater environments. Prior QTL mapping showed that both traits are partially controlled by overlapping genomic regions on chromosome 21 and that a regulatory change in Bmp6 likely underlies the tooth number QTL. Here, we mapped the branchial bone length QTL to a 155 kb, eight-gene interval tightly linked to, but excluding the coding regions of Bmp6 and containing the candidate gene Tfap2a Further recombinant mapping revealed this bone length QTL is separable into at least two loci. During embryonic and larval development, Tfap2a was expressed in the branchial bone primordia, where allele specific expression assays revealed the freshwater allele of Tfap2a was expressed at lower levels relative to the marine allele in hybrid fish. Induced loss-of function mutations in Tfap2a revealed an essential role in stickleback craniofacial development and show that bone length is sensitive to Tfap2a dosage in heterozygotes. Combined, these results suggest that closely linked but genetically separable changes in Bmp6 and Tfap2a contribute to a supergene underlying evolved skeletal gain in multiple freshwater stickleback populations. PMID- 29593030 TI - Stem Cell Properties of Normal Human Keratinocytes Determine Transformation Responses to Human Papillomavirus 16 DNA. AB - Human papillomavirus (HPV) infection of the genital tract is common; however, only about 10 to 15% of infections persist, and approximately 10 to 15% of these persistent infections result in cancer. Basal epidermal stem cells are the presumed target cells for HPV infection, providing a reservoir of latently infected cells that persist over time and initiate lesions. However, it is not known whether stem cell density has any influence on transformation of human keratinocytes by HPV. We explored the relationship between stem cell properties of normal human keratinocytes and their susceptibility to transformation by HPV16 DNA. Normal human keratinocyte isolates (NHKc) derived from different donors were cultured in three-dimensional anchorage-free suspension to assess their spheroid forming ability. NHKc spheroids were then plated back into plastic monolayer culture and transfected with full-length HPV16 DNA, which we have previously shown to integrate into the host cell genome upon transfection. Spheroid-derived NHKc (SD-NHKc) and fluorescence-activated cell sorting-purified populations of basal stem-like keratinocytes, expressing low levels of epidermal growth factor receptor and high levels of integrin alpha 6 (EGFRlo/ITGalpha6hi), responded to transfection with HPV16 DNA with more vigorous proliferation, greater immortalization efficiency, and faster progression to differentiation resistance than autologous mass-cultured cells. Conversely, cells committed to terminal differentiation (EGFRhi/ITGalpha6lo) grew slowly after transfection with HPV16 and failed to generate immortalized or DR clones. HPV16 DNA induced stem cell properties in mass-cultured NHKc. We conclude that HPV16 preferentially immortalizes basal keratinocytes with stem cell properties and that these cells readily achieve a differentiation-resistant phenotype upon immortalization by HPV16.IMPORTANCE This paper explores the relationship between the stem cell properties of normal human epidermal cells in culture and these cells' susceptibility to transformation by HPV16 DNA, the HPV type present in about 50% of cervical cancers. We report variable susceptibilities to HPV16-mediated transformation among different keratinocyte isolates derived from neonatal foreskin. Our findings provide strong experimental evidence that HPV16 preferentially transforms basal keratinocytes with stem cell properties. Insights gained from these studies increase our understanding of the host cell-specific factors influencing individual susceptibility to HPV-driven transformation and the contributing factors leading to preneoplastic and neoplastic progression of HPV-positive lesions. PMID- 29593031 TI - Central Role of the NF-kappaB Pathway in the Scgb1a1-Expressing Epithelium in Mediating Respiratory Syncytial Virus-Induced Airway Inflammation. AB - Lower respiratory tract infection with respiratory syncytial virus (RSV) produces profound inflammation. Despite an understanding of the role of adaptive immunity in RSV infection, the identity of the major sentinel cells initially triggering inflammation is controversial. Here we evaluate the role of nonciliated secretoglobin (Scgb1a1)-expressing bronchiolar epithelial cells in RSV infection. Mice expressing a tamoxifen (TMX)-inducible Cre recombinase-estrogen receptor fusion protein (CreERTM) knocked into the Scgb1a1 locus were crossed with mice that harbor a RelA conditional allele (RelAfl ), with loxP sites flanking exons 5 to 8 of the Rel homology domain. The Scgb1a1CreERTM/+ * RelAfl/fl mouse is a RelA conditional knockout (RelACKO) of a nonciliated epithelial cell population enriched in the small bronchioles. TMX-treated RelACKO mice have reduced pulmonary neutrophilic infiltration and impaired expression and secretion of NF kappaB-dependent cytokines in response to RSV. In addition, RelACKO mice had reduced expression levels of interferon (IFN) regulatory factor 1/7 (IRF1/7) and retinoic acid-inducible gene I (RIG-I), components of the mucosal IFN positive feedback loop. We demonstrate that RSV replication induces RelA to complex with bromodomain-containing protein 4 (BRD4), a cofactor required for RNA polymerase II (Pol II) phosphorylation, activating the atypical histone acetyltransferase (HAT) activity of BRD4 required for phospho-Ser2 Pol II formation, histone H3K122 acetylation, and cytokine secretion in vitro and in vivo TMX-treated RelACKO mice have less weight loss and reduced airway obstruction/hyperreactivity yet similar levels of IFN-gamma production despite higher levels of virus production. These data indicate that the nonciliated Scgb1a1-expressing epithelium is a major innate sensor for restricting RSV infection by mediating neutrophilic inflammation and chemokine and mucosal IFN production via the RelA-BRD4 pathway.IMPORTANCE RSV infection is the most common cause of infant hospitalizations in the United States, resulting in 2.1 million children annually requiring medical attention. RSV primarily infects nasal epithelial cells, spreading distally to produce severe lower respiratory tract infections. Our study examines the role of a nonciliated respiratory epithelial cell population in RSV infection. We genetically engineered a mouse that can be selectively depleted of the NF-kappaB/RelA transcription factor in this subset of epithelial cells. These mice show an impaired activation of the bromodomain-containing protein 4 (BRD4) coactivator, resulting in reduced cytokine expression and neutrophilic inflammation. During the course of RSV infection, epithelial RelA depleted mice have reduced disease scores and airway hyperreactivity yet increased levels of virus replication. We conclude that RelA-BRD4 signaling in nonciliated bronchiolar epithelial cells mediates neutrophilic airway inflammation and disease severity. This complex is an attractive target to reduce the severity of infection. PMID- 29593032 TI - Extracellular conformational changes in the capsid of human papillomaviruses contribute to asynchronous uptake into host cells. AB - The human papillomavirus type 16 (HPV16) is the leading cause of cervical cancer. For initial infection, HPV16 utilizes a novel endocytic pathway for host cell entry. Unique amongst viruses, uptake occurs asynchronously over a protracted period of time with half-times between 9-12 h. To trigger endocytic uptake, the virus particles need to undergo a series of structural modifications after initial binding to heparan sulfate proteoglycans (HSPG). These changes involve proteolytic cleavage of the major capsid protein L1 by kallikrein-8 (KLK8), exposure of the N-terminus of the minor capsid protein L2 by cyclophilins, and cleavage of this N-terminus by furin. Overall, the structural changes are thought to facilitate the engagement of an elusive secondary receptor for internalization. Here, we addressed whether structural changes are the rate limiting steps during infectious internalization of HPV16 by using structurally primed HPV16 particles. Our findings indicate that the structural modifications mediated by cyclophilins and furin, which lead to exposure and cleavage of the L2 N-terminus, respectively, contribute to the slow and asynchronous internalization kinetics, whereas conformational changes elicited by HSPG binding and KLK8 cleavage did not. However, these structural modifications only accounted for 30 50% of the delay in internalization. Therefore, we propose that limited internalization receptor availability for engagement of HPV16 causes slow and asynchronous internalization in addition to rate-limiting structural changes in the viral capsid.IMPORTANCE HPVs are the main cause for anogenital cancers. Their unique biology is linked to the differentiation program of skin or mucosa. Here, we analyzed another unique aspect of HPV infections using the prototype HPV16. After initial cell binding, HPVs display an unusually protracted residence time on the plasma membrane prior to asynchronous uptake. As viruses typically do not expose themselves to host immune sensing, we analyzed the underlying reasons for this unusual behavior. This study provides evidence that both extracellular structural modifications and possibly a limited availability of the internalization receptor contribute to the slow internalization process of the virus. These findings indicated that perhaps a unique niche for initial infection exists that could allow for rapid infection. In addition, our results may help to develop novel, preventive antiviral measures. PMID- 29593034 TI - Deaminase-Dead Mouse APOBEC3 Is an In Vivo Retroviral Restriction Factor. AB - The apolipoprotein B editing complex 3 (APOBEC3) proteins are potent retroviral restriction factors that are under strong positive selection, both in terms of gene copy number and sequence diversity. A common feature of all the members of the APOBEC3 family is the presence of one or two cytidine deamination domains, essential for cytidine deamination of retroviral reverse transcripts as well as packaging into virions. Several studies have indicated that human and mouse APOBEC3 proteins restrict retrovirus infection via cytidine deaminase (CD) dependent and -independent means. To understand the relative contribution of CD independent restriction in vivo, we created strains of transgenic mice on an APOBEC3 knockout background that express a deaminase-dead mouse APOBEC3 due to point mutations in both CD domains (E73Q/E253Q). Here, we show that the CD-dead APOBEC3 can restrict murine retroviruses in vivo Moreover, unlike the wild-type protein, the mutant APOBEC3 is not packaged into virions but acts only as a cell intrinsic restriction factor that blocks reverse transcription by incoming viruses. Finally, we show that wild-type and CD-dead mouse APOBEC3 can bind to murine leukemia virus (MLV) reverse transcriptase. Our findings suggest that the mouse APOBEC3 cytidine deaminase activity is not required for retrovirus restriction.IMPORTANCE APOBEC3 proteins are important host cellular restriction factors essential for restricting retrovirus infection by causing mutations in the virus genome and by blocking reverse transcription. While both methods of restriction function in vitro, little is known about their role during in vivo infection. By developing transgenic mice with mutations in the cytidine deamination domains needed for enzymatic activity and interaction with viral RNA, we show that APOBEC3 proteins can still restrict in vivo infection by interacting with reverse transcriptase and blocking its activity. These studies demonstrate that APOBEC3 proteins have evolved multiple means for blocking retrovirus infection and that all of these means function in vivo.

AB - Mammarenaviruses cause chronic infections in their natural rodent hosts. Infected rodents shed infectious virus into excreta. Humans are infected through mucosal exposure to aerosols or direct contact of abraded skin with fomites, resulting in a wide range of manifestations from asymptomatic or mild febrile illness to severe life-threatening hemorrhagic fever. The mammarenavirus matrix Z protein has been shown to be a main driving force of virus budding and to act as a negative regulator of viral RNA synthesis. To gain a better understanding of how the Z protein exerts its several different functions, we investigated the interaction between Z and viral polymerase L protein using the prototypic mammarenavirus, lymphocytic choriomeningitis virus (LCMV). We found that in the presence of an active viral ribonucleoprotein (vRNP), the Z protein translocated from nonionic detergent-resistant, membrane-rich structures to a subcellular compartment with a different membrane composition susceptible to disruption by nonionic detergents. Alanine (A) substitution of a highly conserved leucine (L) at position 72 in LCMV Z protein abrogated Z-L interaction. The L72A mutation did not affect the stability or budding activity of Z when expressed alone, but in the presence of an active vRNP, mutation L72A promoted rapid degradation of Z via a proteasome- and lysosome-independent pathway. Accordingly, L72A mutation in the Z protein resulted in nonviable LCMV. Our findings have uncovered novel aspects of the dynamics of the Z protein for which a highly conserved L residue was strictly required.IMPORTANCE Several mammarenaviruses, chiefly Lassa virus (LASV), cause hemorrhagic fever disease in humans and pose important public health concerns in their regions of endemicity. Moreover, mounting evidence indicates that the worldwide-distributed, prototypic mammarenavirus, lymphocytic choriomeningitis virus (LCMV), is a neglected human pathogen of clinical significance. The mammarenavirus matrix Z protein plays critical roles in different steps of the viral life cycle by interacting with viral and host cellular components. Here we report that alanine substitution of a highly conserved leucine residue, located at position 72 in LCMV Z protein, abrogated Z L interaction. The L72A mutation did not affect Z budding activity but promoted its rapid degradation in the presence of an active viral ribonucleoprotein (vRNP). Our findings have uncovered novel aspects of the dynamics of the Z protein for which a highly conserved L residue was strictly required. PMID- 29593033 TI - Human Group C Rotavirus VP8*s Recognize Type A Histo-Blood Group Antigens as Ligands. AB - Group/species C rotaviruses (RVCs) have been identified as important pathogens of acute gastroenteritis (AGE) in children, family-based outbreaks, as well as animal infections. However, little is known regarding their host-specific interaction, infection, and pathogenesis. In this study, we performed serial studies to characterize the function and structural features of a human G4P[2] RVC VP8* that is responsible for the host receptor interaction. Glycan microarrays demonstrated that the human RVC VP8* recognizes type A histo-blood group antigens (HBGAs), which was confirmed by synthetic glycan-/saliva-based binding assays and hemagglutination of red blood cells, establishing a paradigm of RVC VP8*-glycan interactions. Furthermore, the high-resolution crystal structure of the human RVC VP8* was solved, showing a typical galectin-like structure consisting of two beta-sheets but with significant differences from cogent proteins of group A rotaviruses (RVAs). The VP8* in complex with a type A trisaccharide displays a novel ligand binding site that consists of a particular set of amino acid residues of the C-D, G-H, and K-L loops. RVC VP8* interacts with type A HBGAs through a unique mechanism compared with that used by RVAs. Our findings shed light on the host-virus interaction and the coevolution of RVCs and will facilitate the development of specific antivirals and vaccines.IMPORTANCE Group/species C rotaviruses (RVCs), members of Reoviridae family, infect both humans and animals, but our knowledge about the host factors that control host susceptibility and specificity is rudimentary. In this work, we characterized the glycan binding specificity and structural basis of a human RVC that recognizes type A HBGAs. We found that human RVC VP8*, the rotavirus host ligand binding domain that shares only ~15% homology with the VP8* domains of RVAs, recognizes type A HBGA at an as-yet-unknown glycan binding site through a mechanism distinct from that used by RVAs. Our new advancements provide insights into RVC-cell attachment, the critical step of virus infection, which will in turn help the development of control and prevention strategies against RVs. PMID- 29593037 TI - Dynein engages and disassembles cytosol-localized SV40 to promote infection. AB - During entry, polyomavirus (PyV) is endocytosed and sorts to the endoplasmic reticulum (ER) where it penetrates the ER membrane to reach the cytosol. From the cytosol, the virus moves to the nucleus to cause infection. How PyV is transported from the cytosol into the nucleus, a crucial infection step, is unclear. We found that upon reaching the cytosol, the archetype PyV SV40 recruits the cytoplasmic dynein motor, which disassembles the viral particle. This reaction enables the resulting disassembled virus to enter the nucleus to promote infection. Our findings reveal how a cytosolic motor can be hijacked to impart conformational changes to a viral particle, which is essential for successful infection.IMPORTANCE How a non-enveloped virus successfully traffics from the cell surface to the nucleus to cause infection remains enigmatic in many instances. In the case of the non-enveloped PyV, the viral particle is sorted from the plasma membrane to the ER and then the cytosol from where it enters the nucleus to promote infection. The molecular mechanism by which PyV reaches the nucleus from the cytosol is not entirely clear. Here we demonstrate that the prototype PyV SV40 recruits dynein upon reaching the cytosol. Importantly, this cellular motor disassembles the viral particle during cytosol-to-nuclear transport to cause infection. PMID- 29593036 TI - Variation at Extra-epitopic Amino Acid Residues Influences Suppression of Influenza Virus Replication by M158-66 Epitope-Specific CD8+ T Lymphocytes. AB - Influenza virus-specific CD8+ T lymphocytes (CTLs) contribute to clearance of influenza virus infections and reduce disease severity. Variation at amino acid residues located in or outside CTL epitopes has been shown to affect viral recognition by virus-specific CTLs. In the present study, we investigated the effect of naturally occurring variation at residues outside the conserved immunodominant and HLA*0201-restricted M158-66 epitope, located in the influenza virus M1 protein, on the extent of virus replication in the presence of CTLs specific for the epitope. To this end, we used isogenic viruses with an M1 gene segment derived from either an avian or a human influenza virus, HLA-transgenic human epithelial cells, human T cell clones specific for the M158-66 epitope or a control epitope, and a novel, purposely developed in vitro system to coculture influenza virus-infected cells with T cells. We found that the M gene segment of a human influenza A/H3N2 virus afforded the virus the capacity to replicate better in the presence of M158-66-specific CTLs than the M gene segment of avian viruses. These findings are in concordance with previously observed differential CTL activation, caused by variation at extra-epitopic residues, and may reflect an immune adaptation strategy of human influenza viruses that allows them to cope with potent CTL immunity to the M158-66 epitope in HLA-A*0201-positive individuals, resulting in increased virus replication and shedding and possibly increasing disease severity.IMPORTANCE Influenza viruses are among the leading causes of acute respiratory tract infections. CD8+ T lymphocytes display a high degree of cross-reactivity with influenza A viruses of various subtypes and are considered an important correlate of protection. Unraveling viral immune evasion strategies and identifying signs of immune adaptation are important for defining the role of CD8+ T lymphocytes in affording protection more accurately. Improving our insight into the interaction between influenza viruses and virus-specific CD8+ T lymphocyte immunity may help to advance our understanding of influenza virus epidemiology, aid in risk assessment of potentially pandemic influenza virus strains, and benefit the design of vaccines that induce more broadly protective immunity. PMID- 29593038 TI - Conformational Stability of the Hemagglutinin of H5N1 Influenza A Viruses Influences Susceptibility to Broadly Neutralizing Stem Antibodies. AB - Vaccines that elicit broadly neutralizing antibodies to the conserved stem of hemagglutinin (HA) are being developed as universal influenza vaccines that protect against influenza across multiple years. However, different influenza virus strains, even those in the same subtype with identical stem sequences, can vary in susceptibility to broadly neutralizing stem antibodies, and the reasons are not understood. Here we studied potential mechanisms underlying the differing sensitivities of a panel of H5N1 HA pseudoviruses to broadly neutralizing stem antibodies. We found that greater HA conformational stability, as measured by thermal inactivation and pH triggering of conformational changes, correlates with reduced neutralization sensitivity and antibody binding to HA under neutral- and low-pH conditions. Our data indicate that the conformational stability of HA is an important attribute of susceptibility to broadly neutralizing stem antibodies and is influenced by residues outside the stem antibody epitopes.IMPORTANCE The influenza virus surface glycoprotein hemagglutinin (HA) mediates virus attachment and membrane fusion between virus and host cells, allowing the viral core to enter the host cell cytoplasm for replication. Fusion occurs when HA undergoes low-pH-induced-conformational changes during endocytosis. Broadly neutralizing antibodies targeted to the conserved stem region of HA interfere with conformational changes required for fusion. Vaccines that elicit such antibodies are being developed as novel universal influenza vaccines for multiyear protection. We investigated why H5N1 HAs from different strains differ in their sensitivity to broadly neutralizing stem antibodies despite having conserved epitopes. We report that HA conformational stability due to residues outside the antibody binding site accounted for much of the variation in susceptibility to neutralization by stem antibodies. These findings highlight the importance of nonepitope residues in influencing neutralization sensitivity to stem antibodies and the complexities in developing universal vaccines targeting conserved epitopes in the HA stem. PMID- 29593039 TI - Interleukin-15-Stimulated Natural Killer Cells Clear HIV-1-Infected Cells following Latency Reversal Ex Vivo. AB - Current efforts toward human immunodeficiency virus (HIV) eradication include approaches to augment immune recognition and elimination of persistently infected cells following latency reversal. Natural killer (NK) cells, the main effectors of the innate immune system, recognize and clear targets using different mechanisms than CD8+ T cells, offering an alternative or complementary approach for HIV clearance strategies. We assessed the impact of interleukin 15 (IL-15) treatment on NK cell function and the potential for stimulated NK cells to clear the HIV reservoir. We measured NK cell receptor expression, antibody-dependent cell-mediated cytotoxicity (ADCC), cytotoxicity, interferon gamma (IFN-gamma) production, and antiviral activity in autologous HIV replication systems. All NK cell functions were uniformly improved by IL-15, and, more importantly, IL-15 treated NK cells were able to clear latently HIV-infected cells after exposure to vorinostat, a clinically relevant latency-reversing agent. We also demonstrate that NK cells from HIV-infected individuals aviremic on antiretroviral therapy can be efficiently stimulated with IL-15. Our work opens a promising line of investigation leading to future immunotherapies to clear persistent HIV infection using NK cells.IMPORTANCE In the search for an HIV cure, strategies to enhance immune function to allow recognition and clearance of HIV-infected cells following latency reversal are being evaluated. Natural killer (NK) cells possess characteristics that can be exploited for immunotherapy against persistent HIV infection. We demonstrate that NK cells from HIV-positive donors can be strongly stimulated with IL-15, improving their antiviral and cytotoxic potential and, more importantly, clearing HIV-infected cells after latency reversal with a clinically relevant drug. Our results encourage further investigation to design NK cell-based immunotherapies to achieve HIV eradication. PMID- 29593040 TI - Within-Host Variations of Human Papillomavirus Reveal APOBEC Signature Mutagenesis in the Viral Genome. AB - Persistent infection with oncogenic human papillomaviruses (HPVs) causes cervical cancer, accompanied by the accumulation of somatic mutations into the host genome. There are concomitant genetic changes in the HPV genome during viral infection; however, their relevance to cervical carcinogenesis is poorly understood. Here, we explored within-host genetic diversity of HPV by performing deep-sequencing analyses of viral whole-genome sequences in clinical specimens. The whole genomes of HPV types 16, 52, and 58 were amplified by type-specific PCR from total cellular DNA of cervical exfoliated cells collected from patients with cervical intraepithelial neoplasia (CIN) and invasive cervical cancer (ICC) and were deep sequenced. After constructing a reference viral genome sequence for each specimen, nucleotide positions showing changes with >0.5% frequencies compared to the reference sequence were determined for individual samples. In total, 1,052 positions of nucleotide variations were detected in HPV genomes from 151 samples (CIN1, n = 56; CIN2/3, n = 68; ICC, n = 27), with various numbers per sample. Overall, C-to-T and C-to-A substitutions were the dominant changes observed across all histological grades. While C-to-T transitions were predominantly detected in CIN1, their prevalence was decreased in CIN2/3 and fell below that of C-to-A transversions in ICC. Analysis of the trinucleotide context encompassing substituted bases revealed that TpCpN, a preferred target sequence for cellular APOBEC cytosine deaminases, was a primary site for C-to-T substitutions in the HPV genome. These results strongly imply that the APOBEC proteins are drivers of HPV genome mutation, particularly in CIN1 lesions.IMPORTANCE HPVs exhibit surprisingly high levels of genetic diversity, including a large repertoire of minor genomic variants in each viral genotype. Here, by conducting deep-sequencing analyses, we show for the first time a comprehensive snapshot of the within-host genetic diversity of high-risk HPVs during cervical carcinogenesis. Quasispecies harboring minor nucleotide variations in viral whole-genome sequences were extensively observed across different grades of CIN and cervical cancer. Among the within-host variations, C to-T transitions, a characteristic change mediated by cellular APOBEC cytosine deaminases, were predominantly detected throughout the whole viral genome, most strikingly in low-grade CIN lesions. The results strongly suggest that within host variations of the HPV genome are primarily generated through the interaction with host cell DNA-editing enzymes and that such within-host variability is an evolutionary source of the genetic diversity of HPVs. PMID- 29593041 TI - Improvement of the Dengue Virus (DENV) Nonhuman Primate Model via a Reverse Translational Approach Based on Dengue Vaccine Clinical Efficacy Data against DENV-2 and -4. AB - Recent data obtained with the live-attenuated tetravalent dengue CYD-TDV vaccine showed higher protective efficacy against dengue virus type 4 (DENV-4) than against DENV-2. In contrast, results from previous studies in nonhuman primates predicted comparable high levels of protection against each serotype. Maximum viral loads achieved in macaques by subcutaneous inoculation of DENV are generally much lower than those observed in naturally dengue virus-infected humans. This may contribute to an overestimation of vaccine efficacy. Using more stringent DENV infection conditions consisting of the intravenous inoculation of 107 50% cell culture infectious doses (CCID50) in CYD-TDV-vaccinated macaques, complete protection (i.e., undetectable viral RNA) was achieved in all 6 monkeys challenged with DENV-4 and in 6/18 of those challenged with DENV-2, including transiently positive animals. All other infected macaques (12/18) developed sustained DENV-2 RNAemia (defined as detection of viral RNA in serum samples) although 1 to 3 log10 units below the levels achieved in control animals. Similar results were obtained with macaques immunized with either CYD-TDV or monovalent (MV) CYD-2. This suggests that partial protection against DENV-2 was mediated mainly by CYD-2 and not by the other CYDs. Postchallenge induction of strong anamnestic responses, suggesting efficient vaccine priming, likely contributed to the reduction of DENV-2 RNAemia. Finally, an inverse correlation between DENV RNA titers postchallenge and vaccine-induced homotypic neutralizing antibody titers prechallenge was found, emphasizing the key role of these antibodies in controlling DENV infection. Collectively, these data show better agreement with reported data on CYD-TDV clinical vaccine efficacy against DENV-2 and DENV-4. Despite inherent limitations of the nonhuman primate model, these results reinforce its value in assessing the efficacy of dengue vaccines.IMPORTANCE The nonhuman primate (NHP) model is the most widely recognized tool for assessing the protective activity of dengue vaccine candidates, based on the prevention of postinfection DENV viremia. However, its use has been questioned after the recent CYD vaccine phase III trials, in which moderate protective efficacy against DENV 2 was reported, despite full protection against DENV-2 viremia previously being demonstrated in CYD-vaccinated monkeys. Using a reverse translational approach, we show here that the NHP model can be improved to achieve DENV-2 protection levels that show better agreement with clinical efficacy. With this new model, we demonstrate that the injection of the CYD-2 component of the vaccine, in either a monovalent or a tetravalent formulation, is able to reduce DENV-2 viremia in all immunized animals, and we provide clear statistical evidence that DENV-2 neutralizing antibodies are able to reduce viremia in a dose-dependent manner. PMID- 29593042 TI - Varicella-Zoster Virus ORF63 Protects Human Neuronal and Keratinocyte Cell Lines from Apoptosis and Changes Its Localization upon Apoptosis Induction. AB - There are many facets of varicella-zoster virus (VZV) pathogenesis that are not fully understood, such as the mechanisms involved in the establishment of lifelong latency, reactivation, and development of serious conditions like postherpetic neuralgia (PHN). Virus-encoded modulation of apoptosis has been suggested to play an important role in these processes. VZV open reading frame 63 (ORF63) has been shown to modulate apoptosis in a cell-type-specific manner, but the impact of ORF63 on cell death pathways has not been examined in isolation in the context of human cells. We sought to elucidate the effect of VZV ORF63 on apoptosis induction in human neuron and keratinocyte cell lines. VZV ORF63 was shown to protect differentiated SH-SY5Y neuronal cells against staurosporine induced apoptosis. In addition, VZV infection did not induce high levels of apoptosis in the HaCaT human keratinocyte line, highlighting a delay in apoptosis induction. VZV ORF63 was shown to protect HaCaT cells against both staurosporine- and Fas ligand-induced apoptosis. Confocal microscopy was utilized to examine VZV ORF63 localization during apoptosis induction. In VZV infection and ORF63 expression alone, VZV ORF63 became more cytoplasmic, with aggregate formation during apoptosis induction. Taken together, this suggests that VZV ORF63 protects both differentiated SH-SY5Y cells and HaCaT cells from apoptosis induction and may mediate this effect through its localization change during apoptosis. VZV ORF63 is a prominent VZV gene product in both productive and latent infection and thus may play a critical role in VZV pathogenesis by aiding neuron and keratinocyte survival.IMPORTANCE VZV, a human-specific alphaherpesvirus, causes chicken pox during primary infection and establishes lifelong latency in the dorsal root ganglia (DRG). Reactivation of VZV causes shingles, which is often followed by a prolonged pain syndrome called postherpetic neuralgia. It has been suggested that the ability of the virus to modulate cell death pathways is linked to its ability to establish latency and reactivate. The significance of our research lies in investigating the ability of ORF63, a VZV gene product, to inhibit apoptosis in novel cell types crucial for VZV pathogenesis. This will allow an increased understanding of critical enigmatic components of VZV pathogenesis. PMID- 29593043 TI - A Vaccine Platform against Arenaviruses Based on a Recombinant Hyperattenuated Mopeia Virus Expressing Heterologous Glycoproteins. AB - Several Old World and New World arenaviruses are responsible for severe endemic and epidemic hemorrhagic fevers, whereas other members of the Arenaviridae family are nonpathogenic. To date, no approved vaccines, antivirals, or specific treatments are available, except for Junin virus. However, protection of nonhuman primates against Lassa fever virus (LASV) is possible through the inoculation of the closely related but nonpathogenic Mopeia virus (MOPV) before challenge with LASV. We reasoned that this virus, modified by using reverse genetics, would represent the basis for the generation of a vaccine platform against LASV and other pathogenic arenaviruses. After showing evidence of exoribonuclease (ExoN) activity in NP of MOPV, we found that this activity was essential for multiplication in antigen-presenting cells. The introduction of multiple mutations in the ExoN site of MOPV NP generated a hyperattenuated strain (MOPVExoN6b) that is (i) genetically stable over passages, (ii) has increased immunogenic properties compared to those of MOPV, and (iii) still promotes a strong type I interferon (IFN) response. MOPVExoN6b was further modified to harbor the envelope glycoproteins of heterologous pathogenic arenaviruses, such as LASV or Lujo, Machupo, Guanarito, Chapare, or Sabia virus in order to broaden specific antigenicity while preserving the hyperattenuated characteristics of the parental strain. Our MOPV-based vaccine candidate for LASV, MOPEVACLASV, was used in a one-shot immunization assay in nonhuman primates and fully protected them from a lethal challenge with LASV. Thus, our hyperattenuated strain of MOPV constitutes a promising new live-attenuated vaccine platform to immunize against several, if not all, pathogenic arenaviruses.IMPORTANCE Arenaviruses are emerging pathogens transmitted to humans by rodents and responsible for endemic and epidemic hemorrhagic fevers of global concern. Nonspecific symptoms associated with the onset of infection make these viruses difficult to distinguish from other endemic pathogens. Moreover, the unavailability of rapid diagnosis in the field delays the identification of the virus and early care for treatment and favors spreading. The vaccination of exposed populations would be of great help to decrease morbidity and human-to-human transmission. Using reverse genetics, we generated a vaccine platform for pathogenic arenaviruses based on a modified and hyperattenuated strain of the nonpathogenic Mopeia virus and showed that the Lassa virus candidate fully protected nonhuman primates from a lethal challenge. These results showed that a rationally designed recombinant MOPV-based vaccine is safe, immunogenic, and efficacious in nonhuman primates. PMID- 29593044 TI - Control of HIV-1 Pathogenesis in Viremic Nonprogressors Is Independent of Gag Specific Cytotoxic T Lymphocyte Responses. AB - Viremic nonprogressors (VNPs) constitute a very scarce group of untreated human immunodeficiency virus type 1 (HIV-1)-infected individuals who maintain stable CD4+ T cell counts despite high levels of HIV-1 replication. The specific factors associated with this atypical control of the HIV infection have been poorly described. Since specific T cell responses seem to be one of the main causes of HIV-1 control in elite controllers, we studied whether HIV-1 Gag-specific cytotoxic T lymphocyte (CTL) responses could also modulate disease control in VNPs. We characterized the immune responses from four VNPs compared to those of five standard progressors (SPs) during the first years of HIV-1 infection. We observed no differences in the breadth and frequency of Gag-specific cellular responses. Furthermore, we obtained 217 HIV-1Gag clonal sequences in which the viral variability of Gag increased over 3 years of infection for synonymous and nonsynonymous mutations in both VNPs and SPs. VNPs evolution rates in gag were comparable to SPs. This observation is in line with a similar accumulation of CTL putative escape mutations in Gag epitopes targeted by CTL responses. Altogether, the absence of viral pathogenesis in VNP individuals seems to be independent of HIV-Gag-specific CTL responses. This novel information guides to the study of alternative mechanism of HIV-1 pathogenesis control.IMPORTANCE Control of HIV infection has been widely studied in elite controllers or long-term nonprogressor models. However, there is a less-known group of individuals, termed viremic nonprogressors (VNPs), who maintain stable CD4+ T cell counts despite high plasma viremia. The mechanisms involved in this remarkable control of HIV-1 pathogenesis clearly have implications for the development of new drugs and vaccines. We show here for the first time that VNPs have immune responses and HIV-gag evolution similar to those of standard progressors. Remarkably, we demonstrate that the mechanism of pathogenesis control in these individuals differs from some elite controllers that are reported to have improved immune control. This is noteworthy since it opens the door to new, as-yet-unknown mechanisms for HIV control. Our novel results advance the understanding of mechanisms involved in viremic nonprogression and suggest that there are alternative mechanisms to the adaptive immune responses for an effective control of viral pathogenesis. PMID- 29593045 TI - Degradation of a novel DNA damage response protein, tankyrase 1 binding protein 1 (Tab182), following adenovirus infection. AB - Infection by most DNA viruses activates a cellular DNA damage response (DDR), which may be to the detriment or advantage of the virus. In the case of adenoviruses, they neutralise anti-viral effects of DDR activation by targeting a number of proteins for rapid proteasome-mediated degradation. We have now identified a novel DDR protein, tankyrase 1 binding protein 1 (TNKS1BP1 also known as Tab182), which is degraded during infection by adenovirus 5 and adenovirus 12. In both cases, degradation requires the action of E1B55K and E4orf6 viral proteins and is mediated through the proteasome by the action of cullin-based cellular E3 ligases. The degradation of Tab182 appears to be serotype specific as the protein remains relatively stable following infection with adenoviruses 4, 7, 9 and 11. We have gone on to confirm that Tab182 is an integral component of the CNOT complex, which has transcriptional regulatory, deadenylation and E3 ligase activity. At least 2 other members of the complex (CNOT3 and CNOT7) are also reduced in level during adenovirus infection whereas levels of CNOT4 and CNOT1 remain stable. Depletion of Tab182 with siRNA enhances expression of E1As to a limited extent during adenovirus infection but depletion of CNOT1 is particularly advantageous to the virus and results in a marked increase in expression of adenovirus early proteins. In addition, depletion of Tab182 and CNOT1 results in a limited increase in viral DNA during infection. We conclude that the cellular CNOT complex is a previously unidentified major target for adenoviruses during infection.ImportanceAdenoviruses target a number of cellular proteins involved in the DNA damage response for rapid degradation. We have now shown that Tab182, which we have confirmed to be an integral component of the mammalian CNOT complex, is degraded following infection by adenovirus serotypes 5 and 12. This requires the viral E1B55K and E4orf6 proteins and is mediated by cullin-based E3 ligases and the proteasome. In addition to Tab182, other CNOT proteins are also reduced during adenovirus infection. Thus, CNOT3 and CNOT7, for example, are degraded whereas CNOT4 and CNOT1 are not. siRNA-mediated depletion of components of the complex enhances the expression of adenovirus early proteins and increases the concentration of viral DNA produced during infection. This study highlights a novel protein complex, CNOT, which is targeted for adenovirus-mediated protein degradation. To our knowledge this is the first time that the CNOT complex has been identified as an adenoviral target. PMID- 29593046 TI - Host Factor SPCS1 Regulates the Replication of Japanese Encephalitis Virus through Interactions with Transmembrane Domains of NS2B. AB - Signal peptidase complex subunit 1 (SPCS1) is a newly identified host factor that regulates flavivirus replication, but the molecular mechanism is not fully understood. Here, using Japanese encephalitis virus (JEV) as a model, we investigated the mechanism through which the host factor SPCS1 regulates the replication of flaviviruses. We first validated the regulatory function of SPCS1 in JEV propagation by knocking down and knocking out endogenous SPCS1. The loss of SPCS1 function markedly reduced intracellular virion assembly and the production of infectious JEV particles but did not affect cell entry, RNA replication, or translation of the virus. SPCS1 was found to interact with nonstructural protein 2B (NS2B), which is involved in posttranslational protein processing and virus assembly. Serial deletion mutation of the JEV NS2B protein revealed that two transmembrane domains, NS2B(1-49) and NS2B(84-131), interact with SPCS1. Further mutagenesis analysis of conserved flavivirus residues in two SPCS1 interaction domains of NS2B demonstrated that G12A, G37A, and G47A in NS2B(1-49) and P112A in NS2B(84-131) weakened the interaction with SPCS1. Deletion mutation of SPCS1 revealed that SPCS1(91-169), which contains two transmembrane domains, was involved in interactions with both NS2B(1-49) and NS2B(84-131). Taken together, these results demonstrate that SPCS1 affects viral replication by interacting with NS2B, thereby influencing the posttranslational processing of JEV proteins and the assembly of virions.IMPORTANCE Understanding virus-host interactions is important for elucidating the molecular mechanisms of virus propagation and identifying potential antiviral targets. Previous reports demonstrated that SPCS1 is involved in the flavivirus life cycle, but the mechanism remains unknown. In this study, we confirmed that SPCS1 participates in the posttranslational protein processing and viral assembly stages of the JEV life cycle but not in the cell entry, genome RNA replication, or translation stages. Furthermore, we found that SPCS1 interacts with two independent transmembrane domains of the flavivirus NS2B protein. NS2B also interacts with NS2A, which is proposed to mediate virus assembly. Therefore, we propose a protein-protein interaction model showing how SPCS1 participates in the assembly of JEV particles. These findings expand our understanding of how host factors participate in the flavivirus replication life cycle and identify potential antiviral targets for combating flavivirus infection. PMID- 29593047 TI - Interleukin-27R Signaling Mediates Early Viral Containment and Impacts Innate and Adaptive Immunity after Chronic Lymphocytic Choriomeningitis Virus Infection. AB - Chronic viral infections represent a major challenge to the host immune response, and a unique network of immunological elements, including cytokines, are required for their containment. By using a model persistent infection with the natural murine pathogen lymphocytic choriomeningitis virus clone 13 (LCMV Cl13) we investigated the role of one such cytokine, interleukin-27 (IL-27), in the control of chronic infection. We found that IL-27 receptor (IL-27R) signaling promoted control of LCMV Cl13 as early as days 1 and 5 after infection and that il27p28 transcripts were rapidly elevated in multiple subsets of dendritic cells (DCs) and myeloid cells. In particular, plasmacytoid DCs (pDCs), the most potent type 1 interferon (IFN-I)-producing cells, significantly increased il27p28 in a Toll-like receptor 7 (TLR7)-dependent fashion. Notably, mice deficient in an IL 27-specific receptor, WSX-1, exhibited a pleiotropy of innate and adaptive immune alterations after chronic lymphocytic choriomeningitis virus (LCMV) infection, including compromised NK cell cytotoxicity and antibody responses. While, the majority of these immune alterations appeared to be cell extrinsic, cell intrinsic IL-27R was necessary to maintain early pDC numbers, which, alongside lower IFN-I transcription in CD11b+ DCs and myeloid cells, may explain the compromised IFN-I elevation that we observed early after LCMV Cl13 infection in IL-27R-deficient mice. Together, these data highlight the critical role of IL-27 in enabling optimal antiviral immunity early and late after infection with a systemic persistent virus and suggest that a previously unrecognized positive feedback loop mediated by IL-27 in pDCs might be involved in this process.IMPORTANCE Persistently replicating pathogens, such as human immunodeficiency virus, hepatitis B virus, and hepatitis C virus, represent major health problems worldwide. These infections impose a long-term challenge on the host immune system, which must be heavily and continuously regulated to keep pathogen replication in check without causing fatal immunopathology. Using a persistently replicating rodent pathogen, LCMV, in its natural host, we identified the cellular sources and effects of one important regulatory pathway, interleukin-27 receptor WSX-1 signaling, that is required for both very early and late restriction of chronic (but not acute) infection. We found that WSX-1 was necessary to promote innate immunity and the development of aberrant adaptive immune responses. This not only highlights the role of IL-27 receptor signaling in regulating distinct host responses that are known to be necessary to control chronic infections, but also positions IL-27 as a potential therapeutic target for their modulation. PMID- 29593048 TI - Effect of Short-Term Antiretroviral Therapy Interruption on Levels of Integrated HIV DNA. AB - Analytic treatment interruption (ATI) studies are required to evaluate strategies aimed at achieving ART-free HIV remission, but the impact of ATI on the viral reservoir remains unclear. We validated a DNA size selection-based assay for measuring levels of integrated HIV DNA and applied it to assess the effects of short-term ATI on the HIV reservoir. Samples from participants from four AIDS Clinical Trials Group ATI studies were assayed for integrated HIV DNA levels. Cryopreserved peripheral blood mononuclear cells (PBMCs) were obtained for 12 participants with available samples pre-ATI and approximately 6 months after ART resumption. Four participants also had samples available during the ATI. The median duration of ATI was 12 weeks. Validation of the HIV integrated DNA size exclusion (HIDE) assay was performed using samples spiked with unintegrated HIV DNA, HIV-infected cell lines, and participant PBMCs. The HIDE assay eliminated 99% of unintegrated HIV DNA species and strongly correlated with the established Alu-gag assay. For the majority of individuals, integrated DNA levels increased during ATI and subsequently declined upon ART resumption. There was no significant difference in the levels of integrated HIV DNA between the pre- and post-ATI time points, with a median ratio of post- to pre-ATI HIV DNA levels of 0.95. Using a new integrated HIV DNA assay, we found minimal change in the levels of integrated HIV DNA in participants who underwent an ATI, followed by 6 months of ART. This suggests that short-term ATI can be conducted without a significant impact on the levels of integrated proviral DNA in the peripheral blood.IMPORTANCE Interventions aimed at achieving sustained antiretroviral therapy (ART)-free HIV remission require treatment interruption trials to assess their efficacy. However, these trials are accompanied by safety concerns related to the expansion of the viral reservoir. We validated an assay that uses an automated DNA size-selection platform for quantifying levels of integrated HIV DNA and is less sample- and labor-intensive than current assays. Using stored samples from AIDS Clinical Trials Group studies, we found that short-term ART discontinuation had minimal impact on integrated HIV DNA levels after ART resumption, providing reassurance about the reservoir effects of short-term treatment interruption trials. PMID- 29593049 TI - Mosquito Saliva Reshapes Alphavirus Infection and Immunopathogenesis. AB - Alphaviruses are transmitted to humans via bites of infected mosquitoes. Although alphaviruses have caused a wide range of outbreaks and crippling disease, the availability of licensed vaccines or antiviral therapies remains limited. Mosquito vectors such as Aedes and Culex are the main culprits in the transmission of alphaviruses. This review explores how mosquito saliva may promote alphavirus infection. Identifying the roles of mosquito-derived factors in alphavirus pathogenesis will generate novel tools to circumvent and control mosquito-borne alphavirus infections in humans. PMID- 29593051 TI - Adaptation to Noise in Human Speech Recognition Unrelated to the Medial Olivocochlear Reflex. AB - Sensory systems constantly adapt their responses to the current environment. In hearing, adaptation may facilitate communication in noisy settings, a benefit frequently (but controversially) attributed to the medial olivocochlear reflex (MOCR) enhancing the neural representation of speech. Here, we show that human listeners (N = 14; five male) recognize more words presented monaurally in ipsilateral, contralateral, and bilateral noise when they are given some time to adapt to the noise. This finding challenges models and theories that claim that speech intelligibility in noise is invariant over time. In addition, we show that this adaptation to the noise occurs also for words processed to maintain the slow amplitude modulations in speech (the envelope) disregarding the faster fluctuations (the temporal fine structure). This demonstrates that noise adaptation reflects an enhancement of amplitude modulation speech cues and is unaffected by temporal fine structure cues. Last, we show that cochlear implant users (N = 7; four male) show normal monaural adaptation to ipsilateral noise. Because the electrical stimulation delivered by cochlear implants is independent from the MOCR, this demonstrates that noise adaptation does not require the MOCR. We argue that noise adaptation probably reflects adaptation of the dynamic range of auditory neurons to the noise level statistics.SIGNIFICANCE STATEMENT People find it easier to understand speech in noisy environments when they are given some time to adapt to the noise. This benefit is frequently but controversially attributed to the medial olivocochlear efferent reflex enhancing the representation of speech cues in the auditory nerve. Here, we show that the adaptation to noise reflects an enhancement of the slow fluctuations in amplitude over time that are present in speech. In addition, we show that adaptation to noise for cochlear implant users is not statistically different from that for listeners with normal hearing. Because the electrical stimulation delivered by cochlear implants is independent from the medial olivocochlear efferent reflex, this demonstrates that adaptation to noise does not require this reflex. PMID- 29593050 TI - eCD4-Ig Variants That More Potently Neutralize HIV-1. AB - The human immunodeficiency virus type 1 (HIV-1) entry inhibitor eCD4-Ig is a fusion of CD4-Ig and a coreceptor-mimetic peptide. eCD4-Ig is markedly more potent than CD4-Ig, with neutralization efficiencies approaching those of HIV-1 broadly neutralizing antibodies (bNAbs). However, unlike bNAbs, eCD4-Ig neutralized all HIV-1, HIV-2, and simian immunodeficiency virus (SIV) isolates that it has been tested against, suggesting that it may be useful in clinical settings, where antibody escape is a concern. Here, we characterize three new eCD4-Ig variants, each with a different architecture and each utilizing D1.22, a stabilized form of CD4 domain 1. These variants were 10- to 20-fold more potent than our original eCD4-Ig variant, with a construct bearing four D1.22 domains (eD1.22-HL-Ig) exhibiting the greatest potency. However, this variant mediated less efficient antibody-dependent cell-mediated cytotoxicity (ADCC) activity than eCD4-Ig itself or several other eCD4-Ig variants, including the smallest variant (eD1.22-Ig). A variant with the same architecture as the original eCD4-Ig (eD1.22 D2-Ig) showed modestly higher thermal stability and best prevented the promotion of infection of CCR5-positive, CD4-negative cells. All three variants, and eCD4 Ig itself, mediated more efficient shedding of the HIV-1 envelope glycoprotein gp120 than did CD4-Ig. Finally, we show that only three D1.22 mutations contributed to the potency of eD1.22-D2-Ig and that introduction of these changes into eCD4-Ig resulted in a variant 9-fold more potent than eCD4-Ig and 2-fold more potent than eD1.22-D2-Ig. These studies will assist in developing eCD4-Ig variants with properties optimized for prophylaxis, therapy, and cure applications.IMPORTANCE HIV-1 bNAbs have properties different from those of antiretroviral compounds. Specifically, antibodies can enlist immune effector cells to eliminate infected cells, whereas antiretroviral compounds simply interfere with various steps in the viral life cycle. Unfortunately, HIV-1 is adept at evading antibody recognition, limiting the utility of antibodies as a treatment for HIV-1 infection or as part of an effort to eradicate latently infected cells. eCD4-Ig is an antibody-like entry inhibitor that closely mimics HIV-1's obligate receptors. eCD4-Ig appears to be qualitatively different from antibodies, since it neutralizes all HIV-1, HIV-2, and SIV isolates. Here, we characterize three new structurally distinct eCD4-Ig variants and show that each excels in a key property useful to prevent, treat, or cure an HIV-1 infection. For example, one variant neutralized HIV-1 most efficiently, while others best enlisted natural killer cells to eliminate infected cells. These observations will help generate eCD4-Ig variants optimized for different clinical applications. PMID- 29593052 TI - Long-Term Depression Is Independent of GluN2 Subunit Composition. AB - NMDA receptors (NMDARs) mediate both long-term potentiation and long-term depression (LTD) and understanding how a single receptor can initiate both phenomena remains a major question in neuroscience. A prominent hypothesis implicates the NMDAR subunit composition, specifically GluN2A and GluN2B, in dictating the rules of synaptic plasticity. However, studies testing this hypothesis have yielded inconsistent and often contradictory results, especially for LTD. These inconsistent results may be due to challenges in the interpretation of subunit-selective pharmacology and in dissecting out the contributions of differential channel properties versus the interacting proteins unique to GluN2A or GluN2B. In this study, we address the pharmacological and biochemical challenges by using a single-neuron genetic approach to delete NMDAR subunits in conditional knock-out mice. In addition, the recently discovered non ionotropic nature of NMDAR-dependent LTD allowed the rigorous assessment of unique subunit contributions to NMDAR-dependent LTD while eliminating the variable of differential charge transfer. Here we find that neither the GluN2A nor the GluN2B subunit is strictly necessary for either non-ionotropic or ionotropic LTD.SIGNIFICANCE STATEMENT NMDA receptors are key regulators of bidirectional synaptic plasticity. Understanding the mechanisms regulating bidirectional plasticity will guide development of therapeutic strategies to treat the dysfunctional synaptic plasticity in multiple neuropsychiatric disorders. Because of the unique properties of the NMDA receptor GluN2 subunits, they have been postulated to differentially affect synaptic plasticity. However, there has been significant controversy regarding the roles of the GluN2 subunits in synaptic long term depression (LTD). Using single-neuron knock-out of the GluN2 subunits, we show that LTD requires neither GluN2A nor GluN2B. PMID- 29593053 TI - Functional Organization of the Temporal-Parietal Junction for Theory of Mind in Preverbal Infants: A Near-Infrared Spectroscopy Study. AB - Successful human social life requires imagining what others believe or think to understand and predict behavior. This ability, often referred to as theory of mind (ToM), reliably engages a specialized network of temporal and prefrontal brain regions in older children and adults, including selective recruitment of the temporal-parietal junction (TPJ). To date, how and when this specialized brain organization for ToM arises is unknown due to limitations in functional neuroimaging at younger ages. Here, we used the emerging technique of functional near-infrared spectroscopy to measure the functional brain response across parietal, temporal, and prefrontal regions in 7-month-old male and female infants as they viewed different video scenarios of a person searching for a hidden object. Over different conditions, we manipulated whether the person held an accurate (true) or inaccurate (false) belief about the location of the hidden object in the videos. In two separate experiments, we observed that activity from the TPJ, but not other temporal and prefrontal regions, spontaneously tracked with the beliefs of the other person, responding more during scenarios when the other person's belief regarding the location of the object was false compared with scenarios when her belief was true. These results mirror those obtained with adults to show that the TPJ already shows some functional organization relevant to high-level social cognition by around 7 months of age. Furthermore, these results suggest that infants may draw on similar core mechanisms to implicitly track beliefs, as adults do when reasoning explicitly about them.SIGNIFICANCE STATEMENT Humans selectively engage a network of brain regions, including the temporal-parietal junction (TPJ), to track what others think, an ability referred to as theory of mind. How and when this specialized brain organization for high level social cognition arises is unknown. Using the emerging technique of near infrared spectroscopy with 7-month-old infants, we observed that activity of the TPJ, but not other temporal and frontal regions, distinguished between scenarios when another person's belief about the location of the object was false compared with scenarios when the belief was true. These results suggest that a basic neural architecture to understand and predict the actions of others based on their beliefs may be present from the first year of life. PMID- 29593054 TI - Low-Dimensional and Monotonic Preparatory Activity in Mouse Anterior Lateral Motor Cortex. AB - Neurons in multiple brain regions fire trains of action potentials anticipating specific movements, but this "preparatory activity" has not been systematically compared across behavioral tasks. We compared preparatory activity in auditory and tactile delayed-response tasks in male mice. Skilled, directional licking was the motor output. The anterior lateral motor cortex (ALM) is necessary for motor planning in both tasks. Multiple features of ALM preparatory activity during the delay epoch were similar across tasks. First, most neurons showed direction selective activity and spatially intermingled neurons were selective for either movement direction. Second, many cells showed mixed coding of sensory stimulus and licking direction, with a bias toward licking direction. Third, delay activity was monotonic and low-dimensional. Fourth, pairs of neurons with similar direction selectivity showed high spike-count correlations. Our study forms the foundation to analyze the neural circuit mechanisms underlying preparatory activity in a genetically tractable model organism.SIGNIFICANCE STATEMENT Short term memories link events separated in time. Neurons in the frontal cortex fire trains of action potentials anticipating specific movements, often seconds before the movement. This "preparatory activity" has been observed in multiple brain regions, but has rarely been compared systematically across behavioral tasks in the same brain region. To identify common features of preparatory activity, we developed and compared preparatory activity in auditory and tactile delayed response tasks in mice. The same cortical area is necessary for both tasks. Multiple features of preparatory activity, measured with high-density silicon probes, were similar across tasks. We find that preparatory activity is low dimensional and monotonic. Our study forms a foundation for analyzing the circuit mechanisms underlying preparatory activity in a genetically tractable model organism. PMID- 29593055 TI - Validation of the FluoroType MTBDR Assay for Detection of Rifampin and Isoniazid Resistance in Mycobacterium tuberculosis Complex Isolates. AB - For Mycobacterium tuberculosis complex (MTBC), the rapid and accurate diagnosis of drug resistance is crucial to ensure early initiation of appropriate therapy. Recently, a new molecular diagnostic test, the FluoroType MTBDR, aimed at detecting rifampin and isoniazid resistance has become available. This study aimed to evaluate the FluoroType MTBDR in comparison to phenotypic drug susceptibility testing (DST) using M. tuberculosis complex isolates. MTBC isolates underwent phenotypic DST and were tested using the FluoroType MTBDR and Genotype MTBDRplus. Sanger sequencing of the key regions of rpoB, katG, inhA, and aphC was performed for isolates with discordant phenotypic and molecular results. Furthermore, isolates with specific wild-type bands missing in the Genotype MTBDRplus, indicating the presence of a mutation, were investigated by Sanger sequencing. Specificity and sensitivity, defined as the proportions of isolates correctly determined as susceptible and resistant by the FluoroType MTBDR compared to phenotypic DST, were calculated. A total of 180 culture isolates were included; phenotypic DST showed 85 isolates susceptible to isoniazid and rifampin, 7 with isoniazid monoresistance, 7 with rifampin monoresistance, and 81 with multidrug resistance. The specificity of the FluoroType MTBDR was 100% (95% confidence interval [CI], 96.0 to 100%) for both rifampin and isoniazid. The sensitivity was 91.7% (95% CI, 83.6 to 96.6%) for isoniazid and 98.9% (95% CI, 93.8 to 100.0%) for rifampin. The FluoroType MTBDR has a high sensitivity and specificity for the detection of rifampin and isoniazid resistance when using culture isolates.

AB - The FilmArray Respiratory Panel 2 (RP2) is a multiplex in vitro diagnostic test for the simultaneous and rapid (~45-min) detection of 22 pathogens directly from nasopharyngeal swab (NPS) samples. It contains updated (and in some instances redesigned) assays that improve upon the FilmArray Respiratory Panel (RP; version 1.7), with a faster run time. The organisms identified are adenovirus, coronavirus 229E, coronavirus HKU1, coronavirus NL63, coronavirus OC43, human metapneumovirus, human rhinovirus/enterovirus, influenza virus A, influenza virus A H1, influenza virus A H1-2009, influenza virus A H3, influenza virus B, parainfluenza virus 1, parainfluenza virus 2, parainfluenza virus 3, parainfluenza virus 4, respiratory syncytial virus, Bordetella pertussis, Chlamydia pneumoniae, and Mycoplasma pneumoniae Two new targets are included in the FilmArray RP2: Middle East respiratory syndrome coronavirus and Bordetella parapertussis This study provides data from a multicenter evaluation of 1,612 prospectively collected NPS samples, with performance compared to that of the FilmArray RP or PCR and sequencing. The overall percent agreement between the FilmArray RP2 and the comparator testing was 99.2%. The RP2 demonstrated a positive percent agreement of 91.7% or greater for detection of all but three analytes: coronavirus OC43, B. parapertussis, and B. pertussis The FilmArray RP2 also demonstrated a negative percent agreement of >=93.8% for all analytes. Of note, the adenovirus assay detects all genotypes, with a demonstrated increase in sensitivity. The FilmArray RP2 represents a significant improvement over the FilmArray RP, with a substantially shorter run time that could aid in the diagnosis of respiratory infections in a variety of clinical scenarios. PMID- 29593058 TI - Escherichia coli H-Genotyping PCR: a Complete and Practical Platform for Molecular H Typing. AB - In Escherichia coli, more than 180 O groups and 53 H types have been recognized. The O:H serotyping of E. coli strains is an effective method for identifying strains with pathogenic potential and classifying them into clonal groups. In particular, the serotyping of Shiga toxin-producing E. coli (STEC) strains provides valuable information to evaluate the routes, sources, and prevalence of agents in outbreak investigations and surveillance. Here, we present a complete and practical PCR-based H-typing system, E. coli H-genotyping PCR, consisting of 10 multiplex PCR kits with 51 single PCR primer pairs. Primers were designed based on a detailed comparative analysis of sequences from all H-antigen (flagellin)-encoding genes, fliC and its homologs. The specificity of this system was confirmed by using all H type reference strains. Additionally, 362 serotyped wild strains were also used to evaluate its practicality. All 277 H-type identified isolates gave PCR products that corresponded to the results of serological H typing. Moreover, 76 nonmotile and nine untypeable strains could be successfully subtyped into any H type by the PCR system. The E. coli H-genotyping PCR developed here allows broader, rapid, and low-cost subtyping of H types and will assist epidemiological studies as well as surveillance of pathogenic E. coli.

AB - Clinical outcome prediction is major concern to patients with cancer. Various molecular markers in various carcinomas have been identified in the past few decades. However, accurate predictors in chondrosarcoma have not been developed, even though chondrosarcoma is the second most common primary bone tumour. Chondrosarcoma is the cartilage-forming malignancy and shows a wide spectrum of clinicopathological behaviours. The majority of chondrosarcoma grows slowly and rarely metastasises, and adequate surgery leads to a good prognosis. However, wide surgical excision is acquired in high-grade chondrosarcoma, because this tumour is highly resistant to chemotherapy and radiotherapy. To decide best therapy, accurate diagnostic markers are also necessary in chondrosarcoma. It is reported that angiogenesis and lymphangiogenesis increase by chondrosarcoma staging, and they are promoted by leptin and adiponectin. Several microRNAs to regulate vascular endothelial growth factor (VEGF)-A and VEGF-C are also reported. Alpha-methylacyl-CoA racemase and periostin are proposed as new biomarkers for differential diagnosis of enchondroma and chondrosarcoma. This review summarises that chondrosarcoma diagnostic markers are currently reported. PMID- 29593062 TI - Novel selective medium for the isolation of corynebacterium kroppenstedtii from heavily colonised clinical specimens. AB - AIMS: Granulomatous mastitis due to Corynebacterium kroppenstedtii is an increasingly recognised cause of an indolent and distressing mastitis in non lactating females. This slow-growing lipophilic organism is not reliably isolated using routine culture methods. A novel selective culture medium (CKSM) is designed to optimise the isolation of this organism from clinical specimens. METHODS: CKSM contains 10% galactose and Tween 80 (10%) to enhance the growth of C. kroppenstedtii, fosfomycin (100 ug/mL) to suppress the other bacteria, and differentiate C. kroppenstedtii from non-kroppenstedtii lipophilic corynebacteria by esculin hydrolysis. The medium was evaluated for its ability to support the growth of C. kroppenstedtii, selection and differentiation of C. kroppenstedtii from other bacteria in non-sterile clinical specimens. RESULTS: C. kroppenstedtii grew as 1-2 mm colonies with black halo on CKSM within 72 hours of incubation, compared with barely visible pinpoint colonies on routine blood agars. During the four-month period of evaluation with 8896 respiratory specimens, 103 breast specimens, 1903 female genital tract specimens, 617 newborn surface swabs and 10 011 miscellaneous specimens, 186 C. kroppenstedtii were isolated, including 127 (1.4%) respiratory and 59 (0.5%) miscellaneous specimens, 184 of them were found only on CKSM. Besides the three (2.9%) positive breast specimens, 27 (1.4%) high vaginal and endocervical swabs, and 11 (1.8%) surface swabs of newborns were positive for C. kroppenstedtii. CONCLUSIONS: CKSM is a useful addition to routine agar media for the isolation of C. kroppenstedtii, and will be helpful for studying the epidemiology and transmission of this unusual Corynebacterium causing granulomatous mastitis.

PMID- 29593064 TI - A day in the life of chromatin: how enhancer-promoter loops shape daily behavior. AB - Each spring, we get out of bed 1 h ahead of our biological wake-up time due to the misalignment of internal clocks with the light-dark cycle. Genetic discoveries revealed that clock genes encode transcription factors that are expressed throughout many tissues, yet a gap has remained in understanding the temporal dynamics of transcription. Two groups now apply circular chromosome conformation capture and high-throughput sequencing to dissect how "time of day" dependent changes in chromatin drive core clock oscillations. A surprise is the finding that disruption of enhancer-promoter contacts within chromatin leads to an advance in the "wake-up" time of mice. Furthermore, the assembly of transcriptionally active domains of chromatin requires the ordered recruitment of core clock transcription factors each day. These studies show that waking up involves highly dynamic changes in the three-dimensional positioning of genes within the cell. PMID- 29593065 TI - A bone marrow niche-derived molecular switch between osteogenesis and hematopoiesis. AB - Hematopoietic stem cells (HSCs) reside and are maintained in specialized microenvironments within the bone marrow known as niches, which are comprised of various cell types. Among them, leptin receptor (LepR)-expressing CXC chemokine ligand 12 (CXCL12)-abundant reticular (CAR) cells are known to create a niche for HSCs and at the same time to give rise to osteoblasts. These two functions of CAR/LepR+ cells appear to be tightly but inversely regulated to ensure adequate physical space for HSCs. However, how osteogenesis is prevented in CAR cells to maintain spaces available for HSCs and hematopoiesis remains unclear. In this issue of Genes & Development, Seike and colleagues (pp. 359-372) report that the transcription factor early B-cell factor (Ebf3) is preferentially expressed by CAR/LepR+ cells and inhibits CAR cell differentiation into osteoblasts while at the same time maintaining self-renewal of CAR/LepR+ cells. Using conditional knockout and retroviral systems, the investigators show that loss of Ebf3 in CAR cells impairs HSC numbers and leads to osteosclerosis. This study provides novel insights into transcriptional requirements for CAR cell bone formation by identifying Ebf3 as a niche factor secreted from CAR/Lepr+ cells that regulates the interplay between osteogenesis and hematopoiesis. PMID- 29593060 TI - The British Society of Gastroenterology/UK-PBC primary biliary cholangitis treatment and management guidelines. AB - Primary biliary cholangitis (formerly known as primary biliary cirrhosis, PBC) is an autoimmune liver disease in which a cycle of immune mediated biliary epithelial cell injury, cholestasis and progressive fibrosis can culminate over time in an end-stage biliary cirrhosis. Both genetic and environmental influences are presumed relevant to disease initiation. PBC is most prevalent in women and those over the age of 50, but a spectrum of disease is recognised in adult patients globally; male sex, younger age at onset (<45) and advanced disease at presentation are baseline predictors of poorer outcome. As the disease is increasingly diagnosed through the combination of cholestatic serum liver tests and the presence of antimitochondrial antibodies, most presenting patients are not cirrhotic and the term cholangitis is more accurate. Disease course is frequently accompanied by symptoms that can be burdensome for patients, and management of patients with PBC must address, in a life-long manner, both disease progression and symptom burden. Licensed therapies include ursodeoxycholic acid (UDCA) and obeticholic acid (OCA), alongside experimental new and re-purposed agents. Disease management focuses on initiation of UDCA for all patients and risk stratification based on baseline and on-treatment factors, including in particular the response to treatment. Those intolerant of treatment with UDCA or those with high-risk disease as evidenced by UDCA treatment failure (frequently reflected in trial and clinical practice as an alkaline phosphatase >1.67 * upper limit of normal and/or elevated bilirubin) should be considered for second-line therapy, of which OCA is the only currently licensed National Institute for Health and Care Excellence recommended agent. Follow-up of patients is life-long and must address treatment of the disease and management of associated symptoms. PMID- 29593067 TI - Plasma MOTS-c levels are associated with insulin sensitivity in lean but not in obese individuals. AB - Mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) is a mitochondrial derived peptide that attenuates weight gain and hyperinsulinemia when administered to high fat-fed mice. MOTS-c is therefore a potential regulator of metabolic homeostasis under conditions of high-energy supply. However, the effect of insulin resistance and obesity on plasma MOTS-c concentration in humans is unknown. To gain insight into MOTS-c regulation, we measured plasma MOTS-c concentration and analyzed its relationship with insulin sensitivity surrogates, in lean and obese humans (n=10 per group). Obese individuals had impaired insulin sensitivity as indicated by low Matsuda and high Homeostatic Model Assessment (HOMA) indexes. Although plasma MOTS-c concentration was similar in lean and obese individuals (0.48+/-0.16 and 0.52+/-0.15 ng/mL; p=0.60), it was correlated with HOMA (r=0.53; p<0.05) and Matsuda index (r=-0.46; p<0.05). Notably, when the groups were analyzed separately, the associations remained only in lean individuals. We conclude that plasma MOTS-c concentration is unaltered in human obesity. However, MOTS-c associates positively with insulin resistance mostly in lean individuals, indicating that plasma MOTS-c concentration depends on the metabolic status in this population. Such dependence seems altered when obesity settles. The implications of plasma MOTS-c for human metabolic homeostasis deserve future examination.

AB - Necroptosis, a form of regulated necrotic cell death mediated by RIPK1 (receptor interacting protein kinase 1) kinase activity, RIPK3, and MLKL (mixed-lineage kinase domain-like pseudokinase), can be activated under apoptosis-deficient conditions. Modulating the activation of RIPK1 by ubiquitination and phosphorylation is critical to control both necroptosis and apoptosis. Mutant mice with kinase-dead RIPK1 or RIPK3 and MLKL deficiency show no detrimental phenotype in regard to development and adult homeostasis. However, necroptosis and apoptosis can be activated in response to various mutations that result in the abortion of the defective embryos and human inflammatory and neurodegenerative pathologies. RIPK1 inhibition represents a key therapeutic strategy for treatment of diseases where blocking both necroptosis and apoptosis can be beneficial.

PMID- 29593071 TI - Synaptotagmin 7 Mediates Both Facilitation and Asynchronous Release at Granule Cell Synapses. AB - When an action potential invades a presynaptic terminal it evokes large, brief Ca2+ signals that trigger vesicle fusion within milliseconds that is followed by a small residual Ca2+ (Cares) signal. At many synapses Cares produces synaptic facilitation that lasts up to hundreds of milliseconds and, although less common, Cares can also evoke asynchronous release (AR) that persists for tens of milliseconds. The properties of facilitation and AR are very different, which suggests that they are mediated by distinct mechanisms. However, recently it has been shown that the slow calcium sensor synaptotagmin 7 (Syt7) mediates facilitation at many synapses where AR does not occur, and conversely Syt7 can mediate AR without mediating facilitation. Here we study cerebellar granule cell synapses onto stellate cells and Purkinje cells in mice of both sexes to assess the role of Syt7 in these phenomena at the same synapse. This is of particular interest at granule cell synapses where AR is much more calcium dependent and shorter-lived than facilitation. We find that Syt7 can mediate these two processes despite their divergent properties. In Syt7 knock-out animals, facilitation and AR are smaller and shorter lived than in wild-type animals, even though the initial probability of release and Cares signals are unchanged. Although there are short-lived Syt7-independent mechanisms that mediate facilitation and AR in Syt7 KO animals, we find that at granule cell synapses AR and facilitation are both mediated primarily by Syt7.SIGNIFICANCE STATEMENT At synapses made by cerebellar granule cells, presynaptic activity elevates calcium for tens of milliseconds, which in turn evokes both asynchronous release (AR) and synaptic facilitation. AR is more calcium sensitive and shorter-lived than facilitation at these synapses, suggesting that they are mediated by different mechanisms. However, we find that the slow calcium sensor synaptotagmin 7 mediates both of these phenomena. Small, rapidly decaying components of AR and facilitation are present in Syt7 KO animals, indicating that additional mechanisms can contribute to both AR and facilitation at these synapses. PMID- 29593072 TI - A Strategy To Isolate Modifiers of Caenorhabditis elegans Lethal Mutations: Investigating the Endoderm Specifying Ability of the Intestinal Differentiation GATA Factor ELT-2. AB - The ELT-2 GATA factor normally functions in differentiation of the C. elegans endoderm, downstream of endoderm specification. We have previously shown that, if ELT-2 is expressed sufficiently early, it is also able to specify the endoderm and to replace all other members of the core GATA-factor transcriptional cascade (END-1, END-3, ELT-7). However, such rescue requires multiple copies (and presumably overexpression) of the end-1p::elt-2 cDNA transgene; a single copy of the transgene does not rescue. We have made this observation the basis of a genetic screen to search for genetic modifiers that allow a single copy of the end-1p::elt-2 cDNA transgene to rescue the lethality of the end-1 end-3 double mutant. We performed this screen on a strain that has a single copy insertion of the transgene in an end-1 end-3 background. These animals are kept alive by virtue of an extrachromosomal array containing multiple copies of the rescuing transgene; the extrachromosomal array also contains a toxin under heat shock control to counterselect for mutagenized survivors that have been able to lose the rescuing array. A screen of ~14,000 mutagenized haploid genomes produced 17 independent surviving strains. Whole genome sequencing was performed to identify genes that incurred independent mutations in more than one surviving strain. The C. elegans gene tasp-1 was mutated in four independent strains. tasp-1 encodes the C. elegans homolog of Taspase, a threonine-aspartic acid protease that has been found, in both mammals and insects, to cleave several proteins involved in transcription, in particular MLL1/trithorax and TFIIA. A second gene, pqn-82, was mutated in two independent strains and encodes a glutamine-asparagine rich protein. tasp-1 and pqn-82 were verified as loss-of-function modifiers of the end 1p::elt-2 transgene by RNAi and by CRISPR/Cas9-induced mutations. In both cases, gene loss leads to modest increases in the level of ELT-2 protein in the early endoderm although ELT-2 levels do not strictly correlate with rescue. We suggest that tasp-1 and pqn-82 represent a class of genes acting in the early embryo to modulate levels of critical transcription factors or to modulate the responsiveness of critical target genes. The screen's design, rescuing lethality with an extrachromosomal transgene followed by counterselection, has a background survival rate of <10-4 without mutagenesis and should be readily adapted to the general problem of identifying suppressors of C. elegans lethal mutations.

In this study we investigated the role of Vps74 at telomeres and in the DNA damage response. We show that Vps74 decreases the fitness of telomere defective cdc13-1 cells and contributes to the fitness of yku70Delta cells. Importantly, loss of Vps74 in yku70Delta cells exacerbates the temperature dependent growth defects of these cells in a Chk1 and Mec1-dependent manner. Furthermore, Exo1 reduces the fitness of vps74Delta yku70Delta cells suggesting that ssDNA contributes to the fitness defects of vps74Delta yku70Delta cells. Systematic genetic interaction analysis of vps74Delta, yku70Delta and yku70Delta vps74Delta cells suggests that vps74Delta causes a milder but similar defect to that seen in yku70Delta cells. vps74Delta cells have slightly shorter telomeres and loss of VPS74 in yku70Delta or mre11Delta cells further shortens the telomeres of these cells. Interestingly, loss of Vps74 leads to increased levels of Stn1, a partner of Cdc13 in the CST telomere capping complex. Overexpression of Stn1 was previously shown to cause telomere shortening, suppression of cdc13-1 and enhancement of yku70Delta growth defects, suggesting that increased levels of Stn1 may be the route by which Vps74 affects telomere function. These results establish Vps74 as a novel regulator of telomere biology. PMID- 29593075 TI - Support for the placement of Chilesaurus within Ornithischia: a reply to Muller et al.

AB - Cooperatively breeding common marmosets show substantial variation in the amount of help they provide. Pay-to-stay and social prestige models of helping attribute this variation to audience effects, i.e. that individuals help more if group members can witness their interactions with immatures, whereas models of kin selection, group augmentation or those stressing the need to gain parenting experience do not predict any audience effects. We quantified the readiness of adult marmosets to share food in the presence or absence of other group members. Contrary to both predictions, we found a reverse audience effect on food-sharing behaviour: marmosets would systematically share more food with immatures when no audience was present. Thus, helping in common marmosets, at least in related family groups, does not support the pay-to-stay or the social prestige model, and helpers do not take advantage of the opportunity to engage in reputation management. Rather, the results appear to reflect a genuine concern for the immatures' well-being, which seems particularly strong when solely responsible for the immatures. PMID- 29593077 TI - Selective screening for atrial fibrillation using multivariable risk models. AB - OBJECTIVE: Atrial fibrillation can lead to stroke if untreated, and identifying those at higher risk is necessary for cost-effective screening for asymptomatic, paroxysmal atrial fibrillation. Age has been proposed to identify those at risk, but risk models may provide better discrimination. This study compares atrial fibrillation risk models with age for screening for atrial fibrillation. METHODS: Nine atrial fibrillation risk models were compared using the Atherosclerosis Risk in Communities study (11 373 subjects, 60.0+/-5.7 years old). A new risk model (Screening for Asymptomatic Atrial Fibrillation Events-SAAFE) was created using data collected in the Monitoring Disparities in Chronic Conditions study (3790 subjects, 58.9+/-15.3 years old). The primary measure was the fraction of incident atrial fibrillation subjects who should receive treatment due to a high CHA2DS2-VASc score identified when screening a fixed number equivalent to the age criterion. Secondary measures were the C statistic and net benefit. RESULTS: Five risk models were significantly better than age. Age identified 71 (61%) of the subjects at risk for stroke who subsequently developed atrial fibrillation, while the best risk model identified 96 (82%). The newly developed SAAFE model identified 95 (81%), primarily based on age, congestive heart failure and coronary artery disease. CONCLUSIONS: Use of a risk model increases identification of subjects at risk for atrial fibrillation. One of the best performing models (SAAFE) does not require an ECG for its application, so that it could be used instead of age as a screening criterion without adding to the cost. PMID- 29593078 TI - Aortic elongation part I: the normal aortic ageing process. AB - OBJECTIVES: Differentiation between normal and abnormal features of vascular ageing is crucial, as the latter is associated with adverse outcomes. The normal aortic ageing process is accompanied by gradual luminal dilatation and reduction of vessel compliance. However, the influence of age on longitudinal aortic dimensions and geometry has not been well studied. This study aims to describe the normal evolution of aortic length and shape throughout life. METHODS: A total of 210 consecutive patients were prospectively enrolled in this cross-sectional single-centre study. All subjects underwent CT on a third-generation dual-source CT scanner. Morphometric measurements, including measurements of segmental length and tortuosity, were performed on three-dimensional models of the thoracic aorta. RESULTS: The length of the thoracic aorta was significantly related to age (r=0.54) and increased by 59 mm (males) or 66 mm (females) between the ages of 20 and 80 years. Elongation was most pronounced in the proximal descending aorta, which showed an almost 2.5-fold length increase during life. The lengthening of the thoracic aorta was accompanied by a marked change of its geometry: whereas the aortic apex was located between the branch vessels in younger patients, it shifted to a more distalward position in the elderly. CONCLUSIONS: The normal ageing process is accompanied by gradual aortic elongation and a notable change of aortic geometry. Part II of this two-part article investigates the hypothesis that excessive elongation could play a role in the occurrence of acute aortic dissection. PMID- 29593079 TI - Aortic elongation part II: the risk of acute type A aortic dissection. AB - OBJECTIVES: Prophylactic surgery for prevention of acute type A aortic dissection (ATAAD) is reserved for patients with an ascending aortic aneurysm >=55 mm. Identification of additional risk predictors is warranted since over 70% of patients presenting with ATAAD have a non-dilated aorta or an aneurysm that would not have met the diameter criterion for preventative surgery. Aim of the study was to evaluate ascending aortic elongation as a risk factor for ATAAD and to compare aortic lengths between ATAAD patients and healthy controls. METHODS: Aortic lengths and diameters of ATAAD patients were measured on three-dimensional modelled computed tomography and adjusted to predissection dimensions in this cross-sectional single-centre study. Logistic regression was used to evaluate the relation between ATAAD and aortic dimensions. Lengths of different aortic segments were compared with a healthy control group using propensity score matching. RESULTS: Two-hundred and fifty patients were included in the study (ATAAD, n=40; controls, n=210). Ascending aortic length and diameter proved to be independent predictors for ATAAD (OR=5.3, CI 2.5 to 11.4, p<0.001 and OR=8.6, CI 2.4 to 31.0, p=0.001). Eighty patients were matched based on propensity scores (ATAAD n=40, controls n=40). The ascending aorta was longer and more dilated in ATAAD patients compared with healthy controls (78.6+/-8.8 mm vs 68.9+/-7.2 mm, p<0.001, 34.4 mm +/-3.2. vs 39.4 mm +/-5.7, p<0.001, respectively). No differences were found in lengths of the aortic arch and descending aorta. CONCLUSIONS: Ascending aortic length could serve as an independent predictor for ATAAD. Future studies addressing indications for prophylactic surgery should also investigate aortic length.

AB - Blind mole rats of the genus Spalax are the only mammalian species to date for which spontaneous cancer has never been reported and resistance to carcinogen induced cancers has been demonstrated. However, the underlying mechanisms are still poorly understood. The fact that Spalax spp. are also hypoxia-tolerant and long-lived species implies the presence of molecular adaptations to prevent genomic instability, which underlies both cancer and aging. We previously demonstrated the upregulation of transcripts related to DNA replication and repair pathways in Spalax Yet, to date, no direct experimental evidence for improved genomic maintenance has been demonstrated for this genus. Here, we show that compared with skin fibroblasts of the above-ground rat, Spalax carmeli skin fibroblasts in culture resist several types of genotoxic insult, accumulate fewer genotoxic lesions and exhibit an enhanced DNA repair capacity. Our results strongly support that this species has evolved efficient mechanisms to maintain DNA integrity as an adaptation to the stressful conditions in the subterranean habitat. PMID- 29593081 TI - Cuticular gas exchange by Antarctic sea spiders. AB - Many marine organisms and life stages lack specialized respiratory structures, like gills, and rely instead on cutaneous respiration, which they facilitate by having thin integuments. This respiratory mode may limit body size, especially if the integument also functions in support or locomotion. Pycnogonids, or sea spiders, are marine arthropods that lack gills and rely on cutaneous respiration but still grow to large sizes. Their cuticle contains pores, which may play a role in gas exchange. Here, we examined alternative paths of gas exchange in sea spiders: (1) oxygen diffuses across pores in the cuticle, a common mechanism in terrestrial eggshells, (2) oxygen diffuses directly across the cuticle, a common mechanism in small aquatic insects, or (3) oxygen diffuses across both pores and cuticle. We examined these possibilities by modeling diffusive oxygen fluxes across all pores in the body of sea spiders and asking whether those fluxes differed from measured metabolic rates. We estimated fluxes across pores using Fick's law parameterized with measurements of pore morphology and oxygen gradients. Modeled oxygen fluxes through pores closely matched oxygen consumption across a range of body sizes, which means the pores facilitate oxygen diffusion. Furthermore, pore volume scaled hypermetrically with body size, which helps larger species facilitate greater diffusive oxygen fluxes across their cuticle. This likely presents a functional trade-off between gas exchange and structural support, in which the cuticle must be thick enough to prevent buckling due to external forces but porous enough to allow sufficient gas exchange. PMID- 29593082 TI - Heat- and humidity-induced plastic changes in body lipids and starvation resistance in the tropical fly Zaprionus indianus during wet and dry seasons. AB - Insects in tropical wet or dry seasons are likely to cope with starvation stress through plastic changes (developmental as well as adult acclimation) in energy metabolites. Control and experimental groups of Zaprionus indianus flies were reared under wet or dry conditions, but adults were acclimated at different thermal or humidity conditions. Adult flies of the control group were acclimated at 27 degrees C and low (50%) or high (60%) relative humidity (RH). For experimental groups, adult flies were acclimated at 32 degrees C for 1 to 6 days and under low (40%) or high (70%) RH. For humidity acclimation, adult flies were acclimated at 27 degrees C but under low (40%) or high (70%) RH for 1 to 6 days. Plastic changes in experimental groups as compared with the control group (developmental as well as adult acclimation) revealed significant accumulation of body lipids owing to thermal or humidity acclimation of wet season flies, but low humidity acclimation did not change the level of body lipids in dry season flies. Starvation resistance and body lipids were higher in the males of dry season flies but in the females of wet season flies. Adults acclimated under different thermal or humidity conditions exhibited changes in the rate of utilization of body lipids, carbohydrates and proteins. Adult acclimation of wet or dry season flies revealed plastic changes in mean daily fecundity; and a reduction in fecundity under starvation. Thus, thermal or humidity acclimation of adults revealed plastic changes in energy metabolites to support starvation resistance of wet or dry season flies. PMID- 29593083 TI - Presence and persistence of a highly ordered lipid phase state in the avian stratum corneum. AB - To survive high temperatures in a terrestrial environment, animals must effectively balance evaporative heat loss and water conservation. In passerine birds, cutaneous water loss (CWL) is the primary avenue of water loss at thermoneutral temperatures and increases slightly as ambient temperature increases, indicating a change in the permeability of the skin. In the stratum corneum (SC), the outermost layer of the skin, lipids arranged in layers called lamellae serve as the primary barrier to CWL in birds. The permeability of these lamellae depends in large part on the ability of lipid molecules to pack closely together in an ordered orthorhombic phase state. However, as temperature increases, lipids of the SC become more disordered, and may pack in more permeable hexagonal or liquid crystalline phase states. In this study, we used Fourier transform infrared spectroscopy to monitor the phase state of lipids in the SC of house sparrows (Passer domesticus) at skin temperatures ranging from 25 to 50 degrees C. As temperature increased, lipids became slightly more disordered, but remained predominantly in the orthorhombic phase, consistent with the small increase in CWL observed in house sparrows as ambient temperature increases. These results differ considerably from studies on mammalian SC, which find a predominantly hexagonal arrangement of lipids at temperatures above 37 degrees C, and the increased order in avian SC may be explained by longer lipid chain length, scarcity of cholesterol and the presence of cerebrosides. Our results lend further insight into the arrangement and packing of individual lipid molecules in avian SC. PMID- 29593084 TI - Flying Drosophilamelanogaster maintain arbitrary but stable headings relative to the angle of polarized light. AB - Animals must use external cues to maintain a straight course over long distances. In this study, we investigated how the fruit fly Drosophila melanogaster selects and maintains a flight heading relative to the axis of linearly polarized light, a visual cue produced by the atmospheric scattering of sunlight. To track flies' headings over extended periods, we used a flight simulator that coupled the angular velocity of dorsally presented polarized light to the stroke amplitude difference of the animals' wings. In the simulator, most flies actively maintained a stable heading relative to the axis of polarized light for the duration of 15 min flights. We found that individuals selected arbitrary, unpredictable headings relative to the polarization axis, which demonstrates that D. melanogaster can perform proportional navigation using a polarized light pattern. When flies flew in two consecutive bouts separated by a 5 min gap, the two flight headings were correlated, suggesting individuals retain a memory of their chosen heading. We found that adding a polarized light pattern to a light intensity gradient enhanced flies' orientation ability, suggesting D. melanogaster use a combination of cues to navigate. For both polarized light and intensity cues, flies' capacity to maintain a stable heading gradually increased over several minutes from the onset of flight. Our findings are consistent with a model in which each individual initially orients haphazardly but then settles on a heading which is maintained via a self-reinforcing process. This may be a general dispersal strategy for animals with no target destination. PMID- 29593085 TI - A model-based analysis of tissue targeting efficacy of nanoparticles. AB - Tissue targeting is a critical challenge for systemic delivery of drug nanocarriers. To overcome this challenge, major research efforts have been undertaken to design ligand-conjugated nanoparticles. However, limited work has been done to quantitatively assess the effectiveness of such approach. In this work, using a mechanistic spatio-temporal model, I investigate the effectiveness of ligand-directed tissue targeting. By applying an approach from the colloidal filtration theory, I develop a Brownian dynamics model of nanoparticle-cell interaction. The model incorporates a single cell and its surrounding flow field. It considers both specific (receptor-mediated) and non-specific (bare cell surface-mediated) recognition of nanoparticles subject to convective and diffusive motion. Using the model, I investigate how the specific and non specific interactions compare in determining the overall targeting efficacy. My analysis provides some interesting findings that contradict the general notion that effective targeting is possible based upon the differential receptor expression in cancer and non-cancer cells. I show that such strategy may yield only a marginal gain in the targeting efficacy. Moreover, non-specific interaction may have an important influence on particle recognition by cells even at high receptor expression levels. PMID- 29593086 TI - Dynamical patterns underlying response properties of cortical circuits. AB - Recent experimental studies show cortical circuit responses to external stimuli display varied dynamical properties. These include stimulus strength-dependent population response patterns, a shift from synchronous to asynchronous states and a decline in neural variability. To elucidate the mechanisms underlying these response properties and explore how they are mechanistically related, we develop a neural circuit model that incorporates two essential features widely observed in the cerebral cortex. The first feature is a balance between excitatory and inhibitory inputs to individual neurons; the second feature is distance-dependent connectivity. We show that applying a weak external stimulus to the model evokes a wave pattern propagating along lateral connections, but a strong external stimulus triggers a localized pattern; these stimulus strength-dependent population response patterns are quantitatively comparable with those measured in experimental studies. We identify network mechanisms underlying this population response, and demonstrate that the dynamics of population-level response patterns can explain a range of prominent features in neural responses, including changes to the dynamics of neurons' membrane potentials and synaptic inputs that characterize the shift of cortical states, and the stimulus-evoked decline in neuron response variability. Our study provides a unified population activity pattern-based view of diverse cortical response properties, thus shedding new insights into cortical processing. PMID- 29593087 TI - The external scent efferent system of selected European true bugs (Heteroptera): a biomimetic inspiration for passive, unidirectional fluid transport. AB - In this work, we present structured capillaries that were inspired by the microstructures of the external scent efferent system as found in different European true bug species (Pentatomidae and Cydnidae). These make use of small, orientated structures in order to facilitate fluid movement towards desired areas where defensive substances are evaporated. Gland channels and microstructures were investigated by means of scanning electron microscopy and abstracted into three-dimensional models. We used these models to create scent channel replicas from different technical substrates (steel and polymers) by means of laser ablation, laser structuring and casting. Video analysis of conducted fluid-flow experiments showed that bug-inspired, artificial scent fluid channels can indeed transport different fluids (water solutions and oils/lubricants) passively in one direction (velocities of up to 1 mm s-1), while halting the fluid movement in the opposite direction. At the end of this contribution, we present a physical theory that explains the observed fluid transport and sets the rules for performance optimization in future work. PMID- 29593088 TI - Robotic investigation on effect of stretch reflex and crossed inhibitory response on bipedal hopping. AB - To maintain balance during dynamic locomotion, the effects of proprioceptive sensory feedback control (e.g. reflexive control) should not be ignored because of its simple sensation and fast reaction time. Scientists have identified the pathways of reflexes; however, it is difficult to investigate their effects during locomotion because locomotion is controlled by a complex neural system and current technology does not allow us to change the control pathways in living humans. To understand these effects, we construct a musculoskeletal bipedal robot, which has similar body structure and dynamics to those of a human. By conducting experiments on this robot, we investigate the effects of reflexes (stretch reflex and crossed inhibitory response) on posture during hopping, a simple and representative bouncing gait with complex dynamics. Through over 300 hopping trials, we confirm that both the stretch reflex and crossed response can contribute to reducing the lateral inclination during hopping. These reflexive pathways do not use any prior knowledge of the dynamic information of the body such as its inclination. Beyond improving the understanding of the human neural system, this study provides roboticists with biomimetic ideas for robot locomotion control. PMID- 29593089 TI - Language acquisition with communication between learners. AB - We consider a class of students learning a language from a teacher. The situation can be interpreted as a group of child learners receiving input from the linguistic environment. The teacher provides sample sentences. The students try to learn the grammar from the teacher. In addition to just listening to the teacher, the students can also communicate with each other. The students hold hypotheses about the grammar and change them if they receive counter evidence. The process stops when all students have converged to the correct grammar. We study how the time to convergence depends on the structure of the classroom by introducing and evaluating various complexity measures. We find that structured communication between students, although potentially introducing confusion, can greatly reduce some of the complexity measures. Our theory can also be interpreted as applying to the scientific process, where nature is the teacher and the scientists are the students. PMID- 29593090 TI - Expression patterns of cryptochrome genes in avian retina suggest involvement of Cry4 in light-dependent magnetoreception. AB - The light-dependent magnetic compass of birds provides orientation information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina, and be mediated by a light-induced, biochemical radical-pair mechanism involving cryptochromes as putative receptor molecules. At the same time, cryptochromes are known for their role in the negative feedback loop in the circadian clock. We measured gene expression of Cry1, Cry2 and Cry4 in the retina, muscle and brain of zebra finches over the circadian day to assess whether they showed any circadian rhythmicity. We hypothesized that retinal cryptochromes involved in magnetoreception should be expressed at a constant level over the circadian day, because birds use a light-dependent magnetic compass for orientation not only during migration, but also for spatial orientation tasks in their daily life. Cryptochromes serving in circadian tasks, on the other hand, are expected to be expressed in a rhythmic (circadian) pattern. Cry1 and Cry2 displayed a daily variation in the retina as expected for circadian clock genes, while Cry4 expressed at constant levels over time. We conclude that Cry4 is the most likely candidate magnetoreceptor of the light dependent magnetic compass in birds. PMID- 29593091 TI - In vivo atomic force microscopy-infrared spectroscopy of bacteria. AB - A new experimental platform for probing nanoscale molecular changes in living bacteria using atomic force microscopy-infrared (AFM-IR) spectroscopy is demonstrated. This near-field technique is eminently suited to the study of single bacterial cells. Here, we report its application to monitor dynamical changes occurring in the cell wall during cell division in Staphylococcus aureus using AFM to demonstrate the division of the cell and AFM-IR to record spectra showing the thickening of the septum. This work was followed by an investigation into single cells, with particular emphasis on cell-wall signatures, in several bacterial species. Specifically, mainly cell wall components from S. aureus and Escherichia coli containing complex carbohydrate and phosphodiester groups, including peptidoglycans and teichoic acid, could be identified and mapped at nanometre spatial resolution. Principal component analysis of AFM-IR spectra of six living bacterial species enabled the discrimination of Gram-positive from Gram-negative bacteria based on spectral bands originating mainly from the cell wall components. The ability to monitor in vivo molecular changes during cellular processes in bacteria at the nanoscale opens a new platform to study environmental influences and other factors that affect bacterial chemistry. PMID- 29593092 TI - The early mature part of bacterial twin-arginine translocation (Tat) precursor proteins contributes to TatBC receptor binding. AB - The twin-arginine translocation (Tat) pathway transports folded proteins across bacterial membranes. Tat precursor proteins possess a conserved twin-arginine (RR) motif in their signal peptides that is involved in the binding of the proteins to the membrane-associated TatBC receptor complex. In addition, the hydrophobic region in the Tat signal peptides also contributes to TatBC binding, but whether regions beyond the signal-peptide cleavage site are involved in this process is unknown. Here, we analyzed the contribution of the early mature protein part of the Escherichia coli trimethylamine N-oxide reductase (TorA) to productive TatBC receptor binding. We identified substitutions in the 30 amino acids immediately following the TorA signal peptide (30aa-region) that restored export of a transport-defective TorA[KQ]-30aa-MalE precursor, in which the RR residues had been replaced by a lysine-glutamine pair. Some of these substitutions increased the hydrophobicity of the N-terminal part of the 30aa region and thereby likely enhanced hydrophobic substrate-receptor interactions within the hydrophobic TatBC substrate-binding cavity. Another class of substitutions increased the positive net charge of the region's C-terminal part, presumably leading to strengthened electrostatic interactions between the mature substrate part and the cytoplasmic TatBC regions. Furthermore, we identified substitutions in the C-terminal domains of TatB following the transmembrane segment that restored transport of various transport-defective TorA-MalE derivatives. Some of these substitutions most likely affected the orientation or conformation of the flexible, carboxy-proximal helices of TatB. Therefore, we propose that a tight accommodation of the folded mature region by TatB contributes to productive binding of Tat substrates to TatBC. PMID- 29593093 TI - TAILS N-terminomics and proteomics reveal complex regulation of proteolytic cleavage by O-glycosylation. AB - Proteolytic processing is an irreversible post-translational modification functioning as a ubiquitous regulator of cellular activity. Protease activity is tightly regulated via control of gene expression, enzyme and substrate compartmentalization, zymogen activation, enzyme inactivation, and substrate availability. Emerging evidence suggests that proteolysis can also be regulated by substrate glycosylation and that glycosylation of individual sites on a substrate can decrease or, in rare cases, increase its sensitivity to proteolysis. Here, we investigated the relationship between site-specific, mucin type (or GalNAc-type) O-glycosylation and proteolytic cleavage of extracellular proteins. Using in silico analysis, we found that O-glycosylation and cleavage sites are significantly associated with each other. We then used a positional proteomic strategy, terminal amine isotopic labeling of substrates (TAILS), to map the in vivo cleavage sites in HepG2 SimpleCells with and without one of the key initiating GalNAc transferases, GalNAc-T2, and after treatment with exogenous matrix metalloproteinase 9 (MMP9) or neutrophil elastase. Surprisingly, we found that loss of GalNAc-T2 not only increased cleavage, but also decreased cleavage across a broad range of other substrates, including key regulators of the protease network. We also found altered processing of several central regulators of lipid homeostasis, including apolipoprotein B and the phospholipid transfer protein, providing new clues to the previously reported link between GALNT2 and lipid homeostasis. In summary, we show that loss of GalNAc-T2 O-glycosylation leads to a general decrease in cleavage and that GalNAc-T2 O-glycosylation affects key regulators of the cellular proteolytic network, including multiple members of the serpin family. PMID- 29593094 TI - Distinct human alpha(1,3)-fucosyltransferases drive Lewis-X/sialyl Lewis-X assembly in human cells. AB - In humans, six alpha(1,3)-fucosyltransferases (alpha(1,3)-FTs: FT3/FT4/FT5/FT6/FT7/FT9) reportedly fucosylate terminal lactosaminyl glycans yielding Lewis-X (LeX; CD15) and/or sialyl Lewis-X (sLeX; CD15s), structures that play key functions in cell migration, development, and immunity. Prior studies analyzing alpha(1,3)-FT specificities utilized either purified and/or recombinant enzymes to modify synthetic substrates under nonphysiological reaction conditions or molecular biology approaches wherein alpha(1,3)-FTs were expressed in mammalian cell lines, notably excluding investigations using primary human cells. Accordingly, although significant insights into alpha(1,3)-FT catalytic properties have been obtained, uncertainty persists regarding their human LeX/sLeX biosynthetic range across various glycoconjugates. Here, we undertook a comprehensive evaluation of the lactosaminyl product specificities of intracellularly expressed alpha(1,3)-FTs using a clinically relevant primary human cell type, mesenchymal stem cells. Cells were transfected with modified mRNA encoding each human alpha(1,3)-FT, and the resultant alpha(1,3)-fucosylated lactosaminyl glycoconjugates were analyzed using a combination of flow cytometry and MS. The data show that biosynthesis of sLeX is driven by FTs-3, -5, -6, and 7, with FT6 and FT7 having highest potency. FT4 and FT9 dominantly biosynthesize LeX, and, among all FTs, FT6 holds a unique capacity in creating sLeX and LeX determinants across protein and lipid glycoconjugates. Surprisingly, FT4 does not generate sLeX on glycolipids, and neither FT4, FT6, nor FT9 synthesizes the internally fucosylated sialyllactosamine VIM-2 (CD65s). These results unveil the relevant human lactosaminyl glycans created by human alpha(1,3)-FTs, providing novel insights on how these isoenzymes stereoselectively shape biosynthesis of vital glycoconjugates, thereby biochemically programming human cell migration and tuning human immunologic and developmental processes. PMID- 29593095 TI - Loss-of-function PCSK9 mutants evade the unfolded protein response sensor GRP78 and fail to induce endoplasmic reticulum stress when retained. AB - The proprotein convertase subtilisin/kexin type-9 (PCSK9) plays a central role in cardiovascular disease (CVD) by degrading hepatic low-density lipoprotein receptor (LDLR). As such, loss-of-function (LOF) PCSK9 variants that fail to exit the endoplasmic reticulum (ER) increase hepatic LDLR levels and lower the risk of developing CVD. The retention of misfolded protein in the ER can cause ER stress and activate the unfolded protein response (UPR). In this study, we investigated whether a variety of LOF PCSK9 variants that are retained in the ER can cause ER stress and hepatic cytotoxicity. Although overexpression of these PCSK9 variants caused an accumulation in the ER of hepatocytes, UPR activation or apoptosis was not observed. Furthermore, ER retention of endogenous PCSK9 via splice switching also failed to induce the UPR. Consistent with these in vitro studies, overexpression of PCSK9 in the livers of mice had no impact on UPR activation. To elucidate the cellular mechanism to explain these surprising findings, we observed that the 94-kDa glucose-regulated protein (GRP94) sequesters PCSK9 away from the 78-kDa glucose-regulated protein (GRP78), the major activator of the UPR. As a result, GRP94 knockdown increased the stability of GRP78-PCSK9 complex and resulted in UPR activation following overexpression of ER-retained PCSK9 variants relative to WT secreted controls. Given that overexpression of these LOF PCSK9 variants does not cause UPR activation under normal homeostatic conditions, therapeutic strategies aimed at blocking the autocatalytic cleavage of PCSK9 in the ER represent a viable strategy for reducing circulating PCSK9. PMID- 29593096 TI - Myristoylated methionine sulfoxide reductase A is a late endosomal protein. AB - Methionine residues in proteins provide antioxidant defense by reacting with oxidizing species, which oxidize methionine to methionine sulfoxide. Reduction of the sulfoxide back to methionine is catalyzed by methionine sulfoxide reductases, essential for protection against oxidative stress. The nonmyristoylated form of methionine sulfoxide reductase A (MSRA) is present in mitochondria, whereas the myristoylated form has been previously reported to be cytosolic. Despite the importance of MSRA in antioxidant defense, its in vivo binding partners and substrates have not been identified. Starting with a protein array, and followed by immunoprecipitation experiments, colocalization studies, and subcellular fractionation, we identified the late endosomal protein, StAR-related lipid transfer domain-containing 3 (STARD3), as a binding partner of myristoylated MSRA, but not of nonmyristoylated MSRA. STARD3 is known to have both membrane binding and cytosolic domains that are important in STARD3-mediated transport of cholesterol from the endoplasmic reticulum to the endosome. We found that the STARD3 cytosolic domain localizes MSRA to the late endosome. We propose that the previous conclusion that myristoylated MSRA is strictly a cytosolic protein is artifactual and likely due to vigorous overexpression of MSRA. We conclude that myristoylated MSRA is a late endosomal protein that may play a role in lipid metabolism or may protect endosomal proteins from oxidative damage. PMID- 29593097 TI - Active site remodeling during the catalytic cycle in metal-dependent fructose-1,6 bisphosphate aldolases. AB - Crystal structures of two bacterial metal (Zn2+)-dependent d-fructose-1,6 bisphosphate (FBP) aldolases in complex with substrate, analogues, and triose-P reaction products were determined to 1.5-2.0 A resolution. The ligand complexes cryotrapped in native or mutant Helicobacter pylori aldolase crystals enabled a novel mechanistic description of FBP C3-C4 bond cleavage. The reaction mechanism uses active site remodeling during the catalytic cycle, implicating relocation of the Zn2+ cofactor that is mediated by conformational changes of active site loops. Substrate binding initiates conformational changes triggered upon P1 phosphate binding, which liberates the Zn2+-chelating His-180, allowing it to act as a general base for the proton abstraction at the FBP C4 hydroxyl group. A second zinc-chelating His-83 hydrogen bonds the substrate C4 hydroxyl group and assists cleavage by stabilizing the developing negative charge during proton abstraction. Cleavage is concerted with relocation of the metal cofactor from an interior to a surface-exposed site, thereby stabilizing the nascent enediolate form. Conserved residue Glu-142 is essential for protonation of the enediolate form prior to product release. A d-tagatose 1,6-bisphosphate enzymatic complex reveals how His-180-mediated proton abstraction controls stereospecificity of the cleavage reaction. Recognition and discrimination of the reaction products, dihydroxyacetone-P and d-glyceraldehyde 3-P, occurs via charged hydrogen bonds between hydroxyl groups of the triose-Ps and conserved residues, Asp-82 and Asp 255, respectively, and are crucial aspects of the enzyme's role in gluconeogenesis.

AB - : Olaparib is a poly(ADP-ribose) polymerase enzyme inhibitor that is approved for use in patients with advanced ovarian cancer (OC) and genetic BRCA1/2 mutations who have received three or more prior lines of chemotherapy for maintenance treatment of recurrent OC that is in response to platinum-based chemotherapy regardless of BRCA mutation status and for human epidermal growth receptor factor 2-negative metastatic breast cancer with deleterious or suspected deleterious germline BRCA mutations who have previously been treated with chemotherapy in the neoadjuvant, adjuvant, or metastatic setting. Because olaparib is poorly soluble and requires advanced drug delivery techniques to ensure bioavailability, the originally approved 400 mg dose is taken as eight 50 mg capsules twice daily. An alternative melt-extrusion tablet formulation was developed to improve the pharmacokinetic and pharmacodynamic profile of olaparib and reduce the pill burden for patients. The recommended tablet dose is 300 mg twice daily (two 150 mg tablets). Phase III studies with the tablet formulation are ongoing for multiple tumor types. Two studies conducted with the olaparib tablet formulation have reported results: one in platinum-sensitive, BRCA-mutated recurrent OC (SOLO 2) and one that included patients with germline BRCA-mutated metastatic breast cancer (OlympiAD). The tablet is the approved formulation based on the SOLO-2 trial results. Because the capsule and tablet formulations have different bioavailability, physicians must strictly adhere to the dosing instructions provided in the prescribing information. The tablet offers greater convenience for most patients, especially when using olaparib for maintenance therapy. This review discusses the differences between the two formulations, dose determination, and guidance for use of olaparib tablets by patients with OC. Prior to implementing any changes in therapy, health care providers should engage their patients in discussion to support an informed transition between the formulations. IMPLICATIONS FOR PRACTICE: Olaparib has recently been approved for maintenance treatment of recurrent ovarian cancer (OC) that is in response to platinum-based chemotherapy. The originally approved capsule formulation was dosed as 400 mg twice daily (eight 50 mg capsules). The recommended olaparib tablet dose is 300 mg twice daily (two 150 mg tablets). The tablet is the new approved formulation based on the SOLO-2 trial results. Because the capsule and tablet formulations have different bioavailability, physicians must strictly adhere to the dosing instructions provided in the prescribing information. The tablet offers greater convenience for most patients, especially when using olaparib for maintenance therapy. This review discusses the differences between the two formulations, dose determination, and guidance for use of olaparib tablets by patients with OC.

AB - LESSONS LEARNED: A phase I study of the pan-class I phosphoinositide 3-kinase inhibitor pilaralisib (in capsule formulation) in advanced solid tumors established the maximum tolerated dose as 600 mg once daily.The current study investigated pilaralisib in tablet formulation.Pilaralisib tablets were associated with a favorable safety profile and preliminary antitumor activity.Based on pharmacokinetic data, the recommended phase II dose of pilaralisib tablets was established as 400 mg once daily. BACKGROUND: A phase I trial of pilaralisib, an oral pan-class I phosphoinositide 3-kinase (PI3K) inhibitor, established the maximum tolerated dose (MTD) of the capsule formulation in patients with advanced solid tumors as 600 mg once daily. This phase I study investigated pilaralisib in tablet formulation. MATERIALS AND METHODS: Patients with advanced solid tumors received pilaralisib tablets (100 600 mg once daily). Primary endpoints were MTD and safety; secondary and exploratory endpoints included pharmacokinetics (PK), pharmacodynamics, and efficacy. RESULTS: Twenty-two patients were enrolled. No dose-limiting toxicities (DLTs) were reported. The most common treatment-related adverse events were diarrhea (40.9%), fatigue (40.9%), decreased appetite (22.7%), and hyperglycemia (22.7%). Pilaralisib plasma exposure did not appear to increase dose proportionally. Steady-state exposure was higher with pilaralisib tablet formulation at 400 mg than with pilaralisib capsule formulation at 400 or 600 mg (mean area under the curve [AUC0-24] 2,820,000 ng * h/mL vs. 2,653,000 and 1,930,000 ng * h/mL, respectively). Of 18 evaluable patients, 2 (11.1%) had a partial response (PR). CONCLUSION: Pilaralisib tablets were associated with a favorable safety profile and preliminary antitumor activity. MTD was not determined. The recommended phase II dose for pilaralisib tablets, based on PK data, was 400 mg once daily. PMID- 29593100 TI - Development and Validation of a Clinical Score for Cardiovascular Risk Stratification of Long-Term Childhood Cancer Survivors. AB - BACKGROUND: Long-term childhood cancer survivors (CCS) are at increased risk of adverse cardiovascular events; however, there is a paucity of risk-stratification tools to identify those at higher-than-normal risk. SUBJECTS, MATERIALS, AND METHODS: This was a population-based study using data from the Surveillance, Epidemiology, and End Results Program (1973-2013). Long-term CCS (age at diagnosis <=19 years, survival >=5 years) were followed up over a median time period of 12.3 (5-40.9) years. Independent predictors of cardiovascular mortality (CVM) were combined into a risk score, which was developed in a derivation set (n = 22,374), and validated in separate patient registries (n = 6,437). RESULTS: In the derivation registries, older age at diagnosis (>=10 years vs. reference group of 1-5 years), male sex, non-white race, a history of lymphoma, and a history of radiation were independently associated with an increased risk of CVM among long term CCS (p < .05). A risk score derived from this model (Childhood and Adolescence Cancer Survivor CardioVascular score [CHACS-CV], range: 0-8) showed good discrimination for CVM (Harrell's C-index [95% confidence interval (CI)]: 0.73 [0.68-0.78], p < .001) and identified a high-risk group (CHACS-CV >=6), with cumulative CVM incidence over 30 years of 6.0% (95% CI: 4.3%-8.1%) versus 2.6% (95% CI: 1.8%-3.7%), and 0.7% (95% CI: 0.5%-1.0%) in the mid- (CHACS-CV = 4-5) and low-risk groups (CHACS-CV <=3), respectively (plog-rank < .001). In the validation set, the respective cumulative incidence rates were 4.7%, 3.1%, and 0.8% (plog-rank < .001). CONCLUSION: We propose a simple risk score that can be applied in everyday clinical practice to identify long-term CCS at increased cardiovascular risk, who may benefit from early cardiovascular screening, and risk-reduction strategies. IMPLICATIONS FOR PRACTICE: Childhood cancer survivors (CCS) are known to be at increased cardiovascular risk. Currently available prognostic tools focus on treatment-related adverse events and late development of congestive heart failure, but there is no prognostic model to date to estimate the risk of cardiovascular mortality among long-term CCS. A simple clinical tool is proposed for cardiovascular risk stratification of long-term CCS based on easily obtainable information from their medical history. This scoring system may be used as a first-line screening tool to assist health care providers in identifying those who may benefit from closer follow-up and enable timely deployment of preventive strategies. PMID- 29593101 TI - Thalidomide Reduces Hemorrhage of Brain Arteriovenous Malformations in a Mouse Model. AB - BACKGROUND AND PURPOSE: Brain arteriovenous malformation (bAVM) is an important risk factor for intracranial hemorrhage. Current treatments for bAVM are all associated with considerable risks. There is no safe method to prevent bAVM hemorrhage. Thalidomide reduces nose bleeding in patients with hereditary hemorrhagic telangiectasia, an inherited disorder characterized by vascular malformations. In this study, we tested whether thalidomide and its less toxic analog, lenalidomide, reduce bAVM hemorrhage using a mouse model. METHODS: bAVMs were induced through induction of brain focal activin-like kinase 1 (Alk1, an AVM causative gene) gene deletion and angiogenesis in adult Alk1-floxed mice. Thalidomide was injected intraperitoneally twice per week for 6 weeks, starting either 2 or 8 weeks after AVM induction. Lenalidomide was injected intraperitoneally daily starting 8 weeks after AVM induction for 6 weeks. Brain samples were collected at the end of the treatments for morphology, mRNA, and protein analyses. The influence of Alk1 downregulation on PDGFB (platelet-derived growth factor B) expression was also studied on cultured human brain microvascular endothelial cells. The effect of PDGFB in mural cell recruitment in bAVM was explored by injection of a PDGFB overexpressing lentiviral vector to the mouse brain. RESULTS: Thalidomide or lenalidomide treatment reduced the number of dysplastic vessels and hemorrhage and increased mural cell (vascular smooth muscle cells and pericytes) coverage in the bAVM lesion. Thalidomide reduced the burden of CD68+ cells and the expression of inflammatory cytokines in the bAVM lesions. PDGFB expression was reduced in ALK1-knockdown human brain microvascular endothelial cells and in mouse bAVM lesion. Thalidomide increased Pdgfb expression in bAVM lesion. Overexpression of PDGFB mimicked the effect of thalidomide. CONCLUSIONS: Thalidomide and lenalidomide improve mural cell coverage of bAVM vessels and reduce bAVM hemorrhage, which is likely through upregulation of Pdgfb expression. PMID- 29593102 TI - A conserved transcriptional response to intranasal Ebola virus exposure in nonhuman primates prior to onset of fever. AB - Ebola virus disease (EVD), caused by Ebola virus (EBOV), is a severe illness characterized by case fatality rates of up to 90%. The sporadic nature of outbreaks in resource-limited areas has hindered the ability to characterize the pathogenesis of EVD at all stages of infection but particularly early host responses. Pathogenesis is often studied in nonhuman primate (NHP) models of disease that replicate major aspects of human EVD. Typically, NHP models use a large infectious dose, are carried out through intramuscular or aerosol exposure, and have a fairly uniform disease course. By contrast, we report our analysis of the host response to EBOV after intranasal exposure. Twelve cynomolgus macaques were infected with 100 plaque-forming units of EBOV/Makona through intranasal exposure and presented with varying times to onset of EVD. We used RNA sequencing and a newly developed NanoString CodeSet to monitor the host response via changes in RNA transcripts over time. When individual animal gene expression data were phased based on the onset of sustained fever, the first clinical sign of severe disease, mathematical models indicated that interferon-stimulated genes appeared as early as 4 days before fever onset. This demonstrates that lethal EVD has a uniform and predictable response to infection regardless of time to onset. Furthermore, expression of a subset of genes could predict disease development before other host-based indications of infection such as fever. PMID- 29593103 TI - The impact of past vaccination coverage and immunity on pertussis resurgence. AB - The resurgence of pertussis over the past decades has resulted in incidence levels not witnessed in the United States since the 1950s. The underlying causes have been the subject of much speculation, with particular attention paid to the shortcomings of the latest generation of vaccines. We formulated transmission models comprising competing hypotheses regarding vaccine failure and challenged them to explain 16 years of highly resolved incidence data from Massachusetts, United States. Our results suggest that the resurgence of pertussis is a predictable consequence of incomplete historical coverage with an imperfect vaccine that confers slowly waning immunity. We found evidence that the vaccine itself is effective at reducing overall transmission, yet that routine vaccination alone would be insufficient for elimination of the disease. Our results indicated that the core transmission group is schoolchildren. Therefore, efforts aimed at curtailing transmission in the population at large, and especially in vulnerable infants, are more likely to succeed if targeted at schoolchildren, rather than adults.

PMID- 29593104 TI - Commensal orthologs of the human autoantigen Ro60 as triggers of autoimmunity in lupus. AB - The earliest autoantibodies in lupus are directed against the RNA binding autoantigen Ro60, but the triggers against this evolutionarily conserved antigen remain elusive. We identified Ro60 orthologs in a subset of human skin, oral, and gut commensal bacterial species and confirmed the presence of these orthologs in patients with lupus and healthy controls. Thus, we hypothesized that commensal Ro60 orthologs may trigger autoimmunity via cross-reactivity in genetically susceptible individuals. Sera from human anti-Ro60-positive lupus patients immunoprecipitated commensal Ro60 ribonucleoproteins. Human Ro60 autoantigen specific CD4 memory T cell clones from lupus patients were activated by skin and mucosal Ro60-containing bacteria, supporting T cell cross-reactivity in humans. Further, germ-free mice spontaneously initiated anti-human Ro60 T and B cell responses and developed glomerular immune complex deposits after monocolonization with a Ro60 ortholog-containing gut commensal, linking anti-Ro60 commensal responses in vivo with the production of human Ro60 autoantibodies and signs of autoimmunity. Together, these data support that colonization with autoantigen ortholog-producing commensal species may initiate and sustain chronic autoimmunity in genetically predisposed individuals. The concept of commensal ortholog cross-reactivity may apply more broadly to autoimmune diseases and lead to novel treatment approaches aimed at defined commensal species. PMID- 29593106 TI - Ablation of the stress protease OMA1 protects against heart failure in mice. AB - Heart failure (HF) is a major health and economic burden in developed countries. It has been proposed that the pathogenesis of HF may involve the action of mitochondria. We evaluate three different mouse models of HF: tachycardiomyopathy, HF with preserved left ventricular (LV) ejection fraction (LVEF), and LV myocardial ischemia and hypertrophy. Regardless of whether LVEF is preserved, our results indicate that the three models share common features: an increase in mitochondrial reactive oxygen species followed by ultrastructural alterations in the mitochondrial cristae and loss of mitochondrial integrity that lead to cardiomyocyte death. We show that the ablation of the mitochondrial protease OMA1 averts cardiomyocyte death in all three murine HF models, and thus loss of OMA1 plays a direct role in cardiomyocyte protection. This finding identifies OMA1 as a potential target for preventing the progression of myocardial damage in HF associated with a variety of etiologies. PMID- 29593107 TI - Social enforcement depending on the stage of colony growth in an ant. AB - Altruism is a paradox in Darwinian evolution. Policing is an important mechanism of the evolution and maintenance of altruism. A recently developed dynamic game model incorporating colony demography and inclusive fitness predicts that, in hymenopteran social insects, policing behaviour enforcing reproductive altruism in group members depends strongly on the colony growth stage, with strong policing as the colony develops and a relaxation of policing during the reproductive phase. Here, we report clear evidence supporting this prediction. In the ant Diacamma sp., reproduction by workers was suppressed by worker policing when the colony was small, whereas in large, mature colonies worker policing was relaxed and worker-produced males emerged. Conditional expression of traits can provide strong empirical evidence for natural selection theory if the expression pattern is precisely predicted by the theory, and our results illustrate the importance of intracolony population dynamics in the evolution of social systems. PMID- 29593108 TI - Artificial light at night shifts daily activity patterns but not the internal clock in the great tit (Parus major). AB - Artificial light at night has shown a dramatic increase over the last decades and continues to increase. Light at night can have strong effects on the behaviour and physiology of species, which includes changes in the daily timing of activity; a clear example is the advance in dawn song onset in songbirds by low levels of light at night. Although such effects are often referred to as changes in circadian timing, i.e. changes to the internal clock, two alternative mechanisms are possible. First, light at night can change the timing of clock controlled activity, without any change to the clock itself; e.g. by a change in the phase relation between the circadian clock and expression of activity. Second, changes in daily activity can be a direct response to light ('masking'), without any involvement of the circadian system. Here, we studied whether the advance in onset of activity by dim light at night in great tits (Parus major) is indeed attributable to a phase shift of the internal clock. We entrained birds to a normal light/dark (LD) cycle with bright light during daytime and darkness at night, and to a comparable (LDim) schedule with dim light at night. The dim light at night strongly advanced the onset of activity of the birds. After at least six days in LD or LDim, we kept birds in constant darkness (DD) by leaving off all lights so birds would revert to their endogenous, circadian system controlled timing of activity. We found that the timing of onset in DD was not dependent on whether the birds were kept at LD or LDim before the measurement. Thus, the advance of activity under light at night is caused by a direct effect of light rather than a phase shift of the internal clock. This demonstrates that birds are capable of changing their daily activity to low levels of light at night directly, without the need to alter their internal clock. PMID- 29593109 TI - To eat or not to eat: ontogeny of hypothalamic feeding controls and a role for leptin in modulating life-history transition in amphibian tadpoles. AB - Many animal life histories entail changing feeding ecology, but the molecular bases for these transitions are poorly understood. The amphibian tadpole is typically a growth and dispersal life-history stage. Tadpoles are primarily herbivorous, and they capitalize on growth opportunities to reach a minimum body size to initiate metamorphosis. During metamorphic climax, feeding declines, at which time the gastrointestinal (GI) tract remodels to accommodate the carnivorous diet of the adult frog. Here we show that anorexigenic hypothalamic feeding controls are absent in the tadpole, but develop during metamorphosis concurrent with the production of the satiety signal leptin. Before metamorphosis there is a large increase in leptin mRNA in fat tissue. Leptin receptor mRNA increased during metamorphosis in the preoptic area/hypothalamus, the key brain region involved with the control of food intake and metabolism. This corresponded with an increase in functional leptin receptor, as evidenced by induction of socs3 mRNA and phosphorylated STAT3 immunoreactivity, and suppression of feeding behaviour after injection of recombinant frog leptin. Furthermore, we found that immunoneutralization of leptin in tadpoles at metamorphic climax caused them to resume feeding. The absence of negative regulation of food intake in the tadpole allows the animal to maximize growth prior to metamorphosis. Maturation of leptin responsive neural circuits suppresses feeding during metamorphosis to facilitate remodelling of the GI tract. PMID- 29593110 TI - Genetic rescue in an inbred Arctic fox (Vulpes lagopus) population. AB - Isolation of small populations can reduce fitness through inbreeding depression and impede population growth. Outcrossing with only a few unrelated individuals can increase demographic and genetic viability substantially, but few studies have documented such genetic rescue in natural mammal populations. We investigate the effects of immigration in a subpopulation of the endangered Scandinavian arctic fox (Vulpes lagopus), founded by six individuals and isolated for 9 years at an extremely small population size. Based on a long-term pedigree (105 litters, 543 individuals) combined with individual fitness traits, we found evidence for genetic rescue. Natural immigration and gene flow of three outbred males in 2010 resulted in a reduction in population average inbreeding coefficient (f), from 0.14 to 0.08 within 5 years. Genetic rescue was further supported by 1.9 times higher juvenile survival and 1.3 times higher breeding success in immigrant first-generation offspring compared with inbred offspring. Five years after immigration, the population had more than doubled in size and allelic richness increased by 41%. This is one of few studies that has documented genetic rescue in a natural mammal population suffering from inbreeding depression and contributes to a growing body of data demonstrating the vital connection between genetics and individual fitness. PMID- 29593111 TI - Concede or clash? Solitary sharks competing for food assess rivals to decide. AB - To adapt to their environment, organisms can either directly interact with their surroundings or use social information (i.e. information provided by neighbouring individuals). Social information relates to the external features of surrounding peers, and little is known about its use by solitary species. Here, we investigated the use of social cues in a solitary marine predator by creating artificial aggregations of free-ranging sicklefin lemon sharks (Negaprion acutidens). Using a novel monitoring protocol, we analysed both dominance interactions and tolerance associations between sharks competing for food in relation with the number, the morphology and the behaviour of rivals. Sharks produced more agonistic displays and spent more time around the bait as competitors were more abundant. Moreover, the morphological attributes of competitors had very limited influence on the structure of shark social interactions. Instead, sharks appeared to establish tolerance relationships with competitors according to their individual behaviour. Furthermore, the more two sharks were observed together at a given study site, the fewer agonistic interactions they exchanged. We discuss these findings as evidence of the use of social cues in a non-gregarious predatory species and suggest directions for future research. PMID- 29593112 TI - Specific adaptation to strong competitors can offset the negative effects of population size reductions. AB - Competition plays a crucial role in determining adaptation of species, yet we know little as to how adaptation is affected by the strength of competition. On the one hand, strong competition typically results in population size reductions, which can hamper adaptation owing to a shortage of beneficial mutations; on the other hand, specificity of adaptation to competitors may offset the negative evolutionary consequences of such population size effects. Here, we investigate how competition strength affects population fitness in the bacterium Pseudomonas fluorescens Our results demonstrate that strong competition constrains adaptation of focal populations, which can be partially explained by population size reductions. However, fitness assays also reveal specific adaptation of focal populations to particular competitors varying in competitive ability. Additionally, this specific adaptation can offset the negative effects of competitor-mediated population size reductions under strong competition. Our study, therefore, highlights the importance of opposing effects of strong competition on species adaptation, which may lead to different outcomes of colonization under intense and relaxed competitive environments in the context of population dispersal. PMID- 29593113 TI - Indirect evolution of social fitness inequalities and facultative social exploitation. AB - Microbial genotypes with similarly high proficiency at a cooperative behaviour in genetically pure groups often exhibit fitness inequalities caused by social interaction in mixed groups. Winning competitors in this scenario have been referred to as 'cheaters' in some studies. Such interaction-specific fitness inequalities, as well as social exploitation (in which interaction between genotypes increases absolute fitness), might evolve due to selection for competitiveness at the focal behaviour or might arise non-adaptively due to pleiotropy, hitchhiking or genetic drift. The bacterium Myxococcus xanthus sporulates during cooperative development of multicellular fruiting bodies. Using M. xanthus lineages that underwent experimental evolution in allopatry without selection on sporulation, we demonstrate that interaction-specific fitness inequalities and facultative social exploitation during development readily evolved indirectly among descendant lineages. Fitness inequalities between evolved genotypes were not caused by divergence in developmental speed, as faster developing strains were not over-represented among competition winners. In competitions between ancestors and several evolved strains, all evolved genotypes produced more spores than the ancestors, including losers of evolved-versus evolved competitions, indicating that adaptation in non-developmental contexts pleiotropically increased competitiveness for spore production. Overall, our results suggest that fitness inequalities caused by social interaction during cooperative processes may often evolve non-adaptively in natural populations. PMID- 29593114 TI - Does observability affect prosociality? AB - The observation of behaviour is a key theoretical parameter underlying a number of models of prosociality. However, the empirical findings showing the effect of observability on prosociality are mixed. In this meta-analysis, we explore the boundary conditions that may account for this variability, by exploring key theoretical and methodological moderators of this link. We identified 117 papers yielding 134 study level effects (total n = 788 164) and found a small but statistically significant, positive association between observability and prosociality (r = 0.141, 95% confidence interval = 0.106, 0.175). Moderator analysis showed that observability produced stronger effects on prosociality: (i) in the presence of passive observers (i.e. people whose role was to only observe participants) versus perceptions of being watched, (ii) when participants' decisions were consequential (versus non-consequential), (iii) when the studies were performed in the laboratory (as opposed to in the field/online), (iv) when the studies used repeated measures (instead of single games), and (v) when the studies involved social dilemmas (instead of bargaining games). These effects show the conditions under which observability effects on prosociality will be maximally observed. We describe the theoretical and practical significance of these results. PMID- 29593115 TI - Do detour tasks provide accurate assays of inhibitory control? AB - Transparent Cylinder and Barrier tasks are used to purportedly assess inhibitory control in a variety of animals. However, we suspect that performances on these detour tasks are influenced by non-cognitive traits, which may result in inaccurate assays of inhibitory control. We therefore reared pheasants under standardized conditions and presented each bird with two sets of similar tasks commonly used to measure inhibitory control. We recorded the number of times subjects incorrectly attempted to access a reward through transparent barriers, and their latencies to solve each task. Such measures are commonly used to infer the differential expression of inhibitory control. We found little evidence that their performances were consistent across the two different Putative Inhibitory Control Tasks (PICTs). Improvements in performance across trials showed that pheasants learned the affordances of each specific task. Critically, prior experience of transparent tasks, either Barrier or Cylinder, also improved subsequent inhibitory control performance on a novel task, suggesting that they also learned the general properties of transparent obstacles. Individual measures of persistence, assayed in a third task, were positively related to their frequency of incorrect attempts to solve the transparent inhibitory control tasks. Neophobia, Sex and Body Condition had no influence on individual performance. Contrary to previous studies of primates, pheasants with poor performance on PICTs had a wider dietary breadth assayed using a free-choice task. Our results demonstrate that in systems or taxa where prior experience and differences in development cannot be accounted for, individual differences in performance on commonly used detour-dependent PICTS may reveal more about an individual's prior experience of transparent objects, or their motivation to acquire food, than providing a reliable measure of their inhibitory control. PMID- 29593116 TI - TGFbeta-facilitated optic fissure fusion and the role of bone morphogenetic protein antagonism. AB - The optic fissure is a transient gap in the developing vertebrate eye, which must be closed as development proceeds. A persisting optic fissure, coloboma, is a major cause for blindness in children. Although many genes have been linked to coloboma, the process of optic fissure fusion is still little appreciated, especially on a molecular level. We identified a coloboma in mice with a targeted inactivation of transforming growth factor beta2 (TGFbeta2). Notably, here the optic fissure margins must have touched, however failed to fuse. Transcriptomic analyses indicated an effect on remodelling of the extracellular matrix (ECM) as an underlying mechanism. TGFbeta signalling is well known for its effect on ECM remodelling, but it is at the same time often inhibited by bone morphogenetic protein (BMP) signalling. Notably, we also identified two BMP antagonists among the downregulated genes. For further functional analyses we made use of zebrafish, in which we found TGFbeta ligands expressed in the developing eye, and the ligand binding receptor in the optic fissure margins where we also found active TGFbeta signalling and, notably, also gremlin 2b (grem2b) and follistatin a (fsta), homologues of the regulated BMP antagonists. We hypothesized that TGFbeta is locally inducing expression of BMP antagonists within the margins to relieve the inhibition from its regulatory capacity regarding ECM remodelling. We tested our hypothesis and found that induced BMP expression is sufficient to inhibit optic fissure fusion, resulting in coloboma. Our findings can likely be applied also to other fusion processes, especially when TGFbeta signalling or BMP antagonism is involved, as in fusion processes during orofacial development. PMID- 29593117 TI - Genetic defects in SAPK signalling, chromatin regulation, vesicle transport and CoA-related lipid metabolism are rescued by rapamycin in fission yeast. AB - Rapamycin inhibits TOR (target of rapamycin) kinase, and is being used clinically to treat various diseases ranging from cancers to fibrodysplasia ossificans progressiva. To understand rapamycin mechanisms of action more comprehensively, 1014 temperature-sensitive (ts) fission yeast (Schizosaccharomyces pombe) mutants were screened in order to isolate strains in which the ts phenotype was rescued by rapamycin. Rapamycin-rescued 45 strains, among which 12 genes responsible for temperature sensitivity were identified. These genes are involved in stress activated protein kinase (SAPK) signalling, chromatin regulation, vesicle transport, and CoA- and mevalonate-related lipid metabolism. Subsequent metabolome analyses revealed that rapamycin upregulated stress-responsive metabolites, while it downregulated purine biosynthesis intermediates and nucleotide derivatives. Rapamycin alleviated abnormalities in cell growth and cell division caused by sty1 mutants (Deltasty1) of SAPK. Notably, in Deltasty1, rapamycin reduced greater than 75% of overproduced metabolites (greater than 2* WT), like purine biosynthesis intermediates and nucleotide derivatives, to WT levels. This suggests that these compounds may be the points at which the SAPK/TOR balance regulates continuous cell proliferation. Rapamycin might be therapeutically useful for specific defects of these gene functions. PMID- 29593118 TI - Entering the post-epigenomic age: back to epigenetics. AB - It is undeniably one of the greatest findings in biology that (with some very minor exceptions) every cell in the body possesses the whole genetic information needed to generate a complete individual. Today, this concept has been so thoroughly assimilated that we struggle to still see how surprising this finding actually was: all cellular phenotypes naturally occurring in one person are generated from genetic uniformity, and thus are per definition epigenetic. Transcriptional mechanisms are clearly critical for developing and protecting cell identities, because a mis-expression of few or even single genes can efficiently induce inappropriate cellular programmes. However, how transcriptional activities are molecularly controlled and which of the many known epigenomic features have causal roles remains unclear. Today, clarification of this issue is more pressing than ever because profiling efforts and epigenome wide association studies (EWAS) continuously provide comprehensive datasets depicting epigenomic differences between tissues and disease states. In this commentary, we propagate the idea of a widespread follow-up use of epigenome editing technology in EWAS studies. This would enable them to address the questions of which features, where in the genome, and which circumstances are essential to shape development and trigger disease states. PMID- 29593120 TI - ROS-mediated activation of AMPK plays a critical role in sulforaphane-induced apoptosis and mitotic arrest in AGS human gastric cancer cells. AB - In this study, we investigated the role of AMP-activated protein kinase (AMPK) and the importance of reactive oxygen species (ROS) in apoptosis induction associated with cell cycle arrest induced by sulforaphane in AGS human gastric cancer cells. Our results demonstrated that sulforaphane inhibited proliferation of AGS cells by promoting apoptosis and accumulating the cellular portion of the G2/M phase via the buildup of cyclin B1 and cyclin-dependent kinase p21 (WAF1/CIP1). Moreover, the phosphorylation of histone H3 was markedly increased following treatment with sulforaphane, indicating that sulforaphane stimulated mitotic arrest. Sulforaphane concurrently induced phosphorylation of AMPK; however, compound C, an AMPK inhibitor, significantly blocked sulforaphane induced apoptosis, suggesting that sulforaphane induces apoptosis of AGS cells through the AMPK-dependent pathway. Sulforaphane also activated the mitochondrial apoptotic signaling pathway with a decrease in mitochondrial membrane potential and the nuclear translocation of cytochrome c. Furthermore, sulforaphane provoked the generation of intracellular ROS; especially when ROS production was blocked by antioxidant N-acetylcysteine, both AMPK activation and growth inhibition by sulforaphane were completely abolished. Collectively, these findings suggest that sulforaphane inhibited growth of AGS cells, which was mediated by a complex interplay between cellular mechanisms governing redox homeostasis, apoptosis, and cell cycle arrest through an ROS/AMPK-dependent pathway. PMID- 29593119 TI - Analysis of the binding mode of a novel HIF1alpha inhibitor through molecular modelling. AB - Hypoxia inducible factor-1 (HIF1) is an important transcription factor related with tumor metastasis. As a subunit of HIF1, HIF1alpha plays an important role in regulation of the hypoxic response. HIF1alpha inhibitor could be a promising treatment for certain cancers. In the present study, we try to model the binding mode of the recent reported new series of HIF1alpha inhibitors with the purpose of further improving the performance of these inhibitors. Molecular docking was first employed to predict the binding modes of the protein-ligand complexes, followed by molecular dynamics simulations and MMGBSA free energy calculations. According to the predicted binding modes, these molecules form two important hydrogen bonds with HIF1alpha. Moreover, if the molecules could form a stable pi pi interaction with HIF1alpha, the potency of the inhibitors can be greatly improved. Hydrophobic interactions between the molecules and HIF1alpha are also a key factor, especially the interactions between the hydrophobic groups (benzimidazole) of the molecules and the hydrophobic residues inside the binding cave. Molecular modeling could be a useful method in the future drug design. In this study, our calculation can help to design and develop high potent HIF1alpha inhibitors in future.

The disease is associated with dopaminergic neuron losses in the substantia nigra area of the brain and the formation of cytoplasmic inclusion bodies. Human glutathione transferase omega 1 (hGSTO1) appears to have a role in modulating stress response. The study was aimed to elucidate differentially expressed proteins caused by oxidative stress induced by 6-hydroxydopamine (6 OHDA). Human neuronal cells SH-SY5Y overexpressing hGSTO1 were used to investigate protein glutathionylation and the modulation of cellular protein expression. Therefore SH-SY5Y/hGSTO1 and SH-SY5Y/control lysate proteins were separated by 2D-gel electrophoresis compared with untreated conditions in both standard and non-reducing conditions. In standard conditions, the analysis of protein profiles demonstrated 25 differentially expressed spots and 10 spots were chosen for further protein identification by LC-MS analysis. Several proteins were later identified as vimentin, galectin-1, high mobility group protein B2, clathrin, tropomyosin, heterogenous nuclear ribonucleoprotein and peroxiredoxin 2. Search Tool for Interactions of Chemicals (STITCH) analysis suggested that oxidative stress induced by 6-OHDA involved carbohydrate metabolism in SH-SY5Y via a lactose metabolic pathway. Our results raise the possibility that hGSTO1 modulates the functions of many proteins that play a role in the degenerative cell response of a Parkinson's model. PMID- 29593122 TI - Inhibition of AT1 receptors by losartan affects myocardial slow force response in healthy but not in monocrotaline-treated young rats. AB - The slow force response (SFR) of a cardiac muscle to a sudden stretch is thought to be important in the regulatory adaptation of myocardial contraction. Autocrine paracrine regulation pathways which involve angiotensin II are participating in this mechanism. On the other hand, renin-angiotensin-aldosterone system (RAS) is altered in hypertrophic or failing myocardium. We compared the effects of sudden stretch to SFR as well as to twitch and Ca2+ transient characteristics in rat myocardium with monocrotaline-induced heart failure with those in normal rat myocardium without and with inhibition of angiotensin II type-1 (AT1) receptors. Our findings indicate that the myocardium of rats with monocrotaline-induced right ventricular failure is deficient with activation of local RAS and therefore expresses blunted SFR, very similar to the depression of SFR observed in normal myocardium under inhibition of AT1 receptors. The "failing" myocardium does not further respond to the "putative" inhibition of AT1 receptors by losartan. In conclusion, SFR is related to autocrine-paracrine regulation of myocardial contraction in normal rat myocardium and that the involvement of RAS into stretch induced modulation of contractility may be significantly altered in failing heart.

AB - In current studies, histopathologic method, Agilent GeneChip hybridization and Western blot were used to investigate the toxicity of acrylamide (AA) and glycidamide (GA) in male mouse livers. The histopathologic results demonstrated that AA and GA could cause oxidative damage to mouse liver. Middle dose of GA and AA (50 mg/kg b.w./day) could significantly up-regulate the expression of cytochrome P450, as well as genes related to oxidative injury, cancer and inflammation, and significantly down-regulate the expression of genes related to anti-apoptosis, antioncogene and fatty acid synthesis. Middle and high dose (75 mg/kg b.w./day) of GA and AA could both down-regulate the expression of hepatic anti-oncogene Bcl2 and up-regulate the expression of cancer-related gene Rad51 and EGFR protein. The expression of anti-oncogene P21 induced by AA and GA was decreased. Our current study demonstrated that the oxidative damage, immune injury and carcinogenicity of mouse liver samples could be induced by AA and GA at histopathological, entire genome and protein levels. PMID- 29593124 TI - Association between 3'UTR polymorphisms in genes ACVR2A, AGTR1 and RGS2 and preeclampsia. AB - Preeclampsia (PE) is a pregnancy specific disease with several risk factors such as genetic polymorphisms, environmental and social factors participating in its development. The aim of this study was to investigate whether distribution of three putative regulatory SNPs rs13430086, rs5186, rs4606 in 3'UTR of genes ACVR2A, AGTR1 and RGS2, respectively, that have been associated with hypertension and regulation of trophoblast invasion differ between women with PE and control group. The associations of rs13430086, rs5186 and rs4606 with preeclampsia were tested in two groups - the group of 50 women with PE and the control group of 42 healthy pregnant women at term. DNA was isolated from blood samples and the determination of genotypes was performed using Real-Time PCR. Power analysis for the size of the cohort was performed and the results were analyzed using Fisher exact test. The AA genotype of ACVR2A rs13430086 was significantly associated with higher risk to preeclampsia compared with TT genotype (p = 0.026, OR: 5.39, 95%CI: 1.21-31.54). Results showed no association between genotypes and preeclampsia for polymorphisms rs5186, rs4606. Further studies are important in order to better understand the role of ACVR2A in the pathogenesis of PE. PMID- 29593125 TI - Upregulation of heme oxygenase 1 (HO-1) attenuates kidney damage, oxidative stress and inflammatory reaction during renal ischemia/ reperfusion injury. AB - The current study investigated the effect of upregulation of heme oxygenase 1 (HO 1) by cobalt protoporphyrin (CoPP) on renal dysfunctions in renal ischemia/reperfusion (I/R) injury and its underlying mechanisms. 72 male Sprague Dawley rats were divided into 4 groups: sham group, ischemic group (left 45-min renal ischemia), CoPP-before group (as ischemic group with CoPP 20 mg/kg 30 min before ischemia) and CoPP-after group (as ischemic group with CoPP 20 mg/kg 20 min after ischemia). Serum creatinine, urea and TGF-beta1 and markers of redox state (MDA, SOD, GSH and CAT), nitric oxide (NO), TGF-beta1 and HO-1 in kidney tissues were measured. Serum creatinine and urea levels were significantly increased in ischemic group and attenuated in CoPP-treated groups (p < 0.05). Also, markers of redox state showed significant deteriorations in ischemic group which were improved significantly in CoPP-treated groups (p < 0.05). HO-1 expression in kidney tissues showed significant increase in ischemic group and showed more significant increase in CoPP-treated groups (p < 0.05). Moreover, serum and renal TGF-beta1 levels were significantly increased in ischemic group and attenuated in CoPP-treated groups (p ? 0.05). We concluded that up-regulation of HO-1 by CoPP treatment before and after renal I/R injury improved the kidney function and morphology and this might be due to impairment of oxidative stress and inflammatory cytokines in kidney tissues. PMID- 29593126 TI - Effect of the allopregnanolone and allotetrahydrodeoxycorticosteron on spike-wave discharges in the EEG of absence epilepsy rat models. AB - Absence epilepsy is a generalized nonconvulsive type of epilepsy that is characterized by spike-wave discharges (SWD) with a frequency of 2.5-4 Hz in the EEG. The activation of the GABAergic system in central nervous system suppresses convulsive seizures but exacerbates absence seizures. Endogenous neuroactive steroids such as 3alpha-hydroxy-5alpha-pregnan-20-one (3alpha,5alpha-THPROG; allopregnanolone) and 3alpha,21-dihydroxy-5alpha-pregnan-20-one (3alpha,5alpha THDOC, allotetrahydrodeoxycorticosteron) are GABA-A receptor-positive allosteric modulators. Finasteride which is a 5alpha-reductase inhibitor can selectively block the synthesis of endogenous steroids. In this study, we compared the effects of endogenous steroids (THPROG and THDOC) on SWD by using finasteride treated Wistar Albino Glaxo from Rijswijk (WAG/Rij) rats as a model of absence epilepsy. Wistar (WIS-THPROG and WIS-THDOC) and WAG/Rij (WAG-THPROG and WAG THDOC) rats were divided into 4 groups (n = 8). After stereotactic surgical procedures, all rats were prepared for direct cortical EEG measurement. Following finasteride administration to each group, THPROG was administered to WIS-THPROG and WAG-THPROG groups, and THDOC to WIS-THDOC and WAG-THDOC groups intraperitoneally. While there was no any SWD activity detected in WIS-THPROG and WIS-THDOC groups, a significant increase in SWD count in WAG-THPROG (p = 0.012) and in WAG-THDOC (p = 0.012), and in SWD total duration in WAG-THPROG (p = 0.012) and WAG-THDOC groups (p = 0.011) were observed after steroid injection. No difference between the efficacy of THPROG and THDOC on absence seizures in WAG/Rij rats was observed. PMID- 29593127 TI - Sulfamethoxazole induces zinc changes at hippocampal mossy fiber synapses from pregnant rats. AB - The accumulation of intracellular ionic zinc and pharmaceutical compounds, like the antibiotic sulfamethoxazole, may contribute to various neuropathologies. Sulfamethoxazole and the drug trimethoprim, are inhibitors of enzymes involved in the synthesis of tetrahydrofolate and also of carbonic anhydrases. The inhibition of the latter enzymes, which are localized both intra- and extracellularly and have a key role in pH regulation, causes alkalinization that is associated with higher spontaneous transmitter release. Intense synaptic stimulation causes the entry of released zinc into postsynaptic neurons, through glutamate receptor channels or voltage dependent calcium channels. The aim of this study was to evaluate the effect of sulfamethoxazole (180 MUM) on basal postsynaptic zinc and to compare it with that caused by two depolarizing media, containing high potassium or tetraethylammonium, which may induce long term synaptic plasticity. The studies were performed in brain slices from gestating rats, at the mossy fiber synapses from hippocampal CA3 area, using the zinc indicator Newport Green. In the presence of KCl (20 mM) and sulfamethoxazole (180 MUM) the zinc signals were enhanced, unlike in tetraethylammonium (25 mM). After sulfamethoxazole the tetraethylammonium evoked zinc signal had reduced amplitude. Thus, the data suggests that sulfamethoxazole enhances transmitter release affecting synaptic zinc physiology. PMID- 29593128 TI - Selective inhibition of smooth muscle plasma membrane transport Sa2+,Mg2+-ATRase by calixarene C-90 and its activation by IPT-35 compound. AB - We investigated the influence of calixarene C-90 and IPT-35 on plasma membrane Ca2+- pumping ATRase (PMCA), intracellular calcium homeostasis and myometrium smooth muscle strain contractions. It has been shown that both effectors (100 MUM) affect PMCA enzymatic activity: calixarene C-90 inhibits it by 75% and IPT 35 activates it by 40%. These compounds don't affect the Mg2+-ATRase, Mg2+ independent Sa2+-ATRase and Na+,K+-ATRase enzymatic activities. C-90 inhibition coefficient I0.5 magnitude was approximately 20 MUM and the Hill coefficient nH was 0.55. For IPT-35 activation, constant A0.5 was 6.4 and nH was 0.7. Mathematical modeling demonstrated the implication of calixarene C-90 on unexcited myocytes, which allows for a precise change in cytoplasm Ca2+ concentration and an influence on basal muscle tonus. By the same method, we determined that IPT-35 has a little influence on Ca2+ concentration in unexcited myocytes. It was also shown that calixarene C-90 in vitro can increase velocity of oxytocin-initiated contractions, whereas IPT-35 can suppress this aforementioned parameter. These results are promising for the design of new pharmacological compounds as better regulators of uterine contractions. Calixarene C-90 can be used in obstetric cases for the simultaneous use of oxytocin for enhancing uterine contractions, and IPT-35 for its antispasmodic effect on uterine tone. PMID- 29593129 TI - Novel neuroprotective role of hydrogen sulfide in a rat model of stress brain injury. AB - Hydrogen sulfide (H2S) is a gaseous mediator recognized as important neuromodulator agent in the central nervous system. Since stress is among the most important factors involved in several pathophysiological brain processes. This study aim to investigate the effect of exogenous H2S on the possible negative effect of stress on the brain of rats and the underlying mechanisms. Rats were divided into 3 groups: control, stressed, H2S treated + stress. Brain injury markers measured were serum S100 protein and gamma enolase. Stress leads to obvious detrimental effects on the brain tissues; it produced significant increase in serum level of the above mentioned brain injury markers, and significant increase in brain levels of nitric oxide (NO), tumor necrosis factor alpha (TNFalpha), and malondialdehyde (MDA) the lipid peroxidation degradative product along with significant decrease in brain glutathione level. H2S pre treatment before stress application abolished the above detrimental effects of stress on the brain tissue since it produced significant decreases in the stressinduced expression of brain injury markers, brain TNFalpha, brain NO and brain MDA, and significant increases in the stress-induced reduction of brain glutathione. H2S has significant neuroprotective role in the nervous system against stress-induced significant brain injury through its antioxidant and anti inflammatory effects. PMID- 29593130 TI - Nonhuman primate breath volatile organic compounds associate with developmental programming and cardio-metabolic status. AB - Rodent and nonhuman primate studies indicate that developmental programming by reduced perinatal nutrition negatively impacts life course cardio-metabolic health. We have developed a baboon model in which we feed control mothers (CON) ad libitum while nutrient restricted mothers are fed 70% of ad libitum global feed in pregnancy and lactation. Offspring of nutrient restricted mothers are intrauterine growth restricted (IUGR) at term. By 3.5 years IUGR baboons showed signs of insulin resistance, indicating a pre-diabetic phenotype, in contrast to healthy CON offspring. We hypothesized that a novel breath analysis approach would provide markers of the altered cardio-metabolic state in a non-invasive manner. Here we assess whether exhaled breath volatile organic compounds (VOCs) collected from this unique cohort of juvenile baboons with documented cardio metabolic dysfunction resulting from in utero programming can be detected from their breath signatures. Breath was collected from male and female CON and IUGR baboons at 4.8 +/- 0.2 years (human equivalent ~13 years). Breath VOCs were quantified using a two-dimensional gas chromatography mass spectrometer. Two-way ANOVA, on 76 biologically relevant VOCs identified 27 VOCs (p < 0.05) with altered abundances between groups (sex, birthweight, and sex x birthweight). The 27 VOCs included 2-pentanone, 2-octanone, 2,2,7,7-tetramethyloctane and 3-methyl 1-heptene, which have not previously been associated with cardio-metabolic disease. Unsupervised principal component analysis of these VOCs could discriminate the four clusters defining males, females, CON and IUGR. This study, which is the first to assess quantifiable breath signatures associated with cardio-metabolic programing for any model of IUGR, demonstrates the translational value of this unique model to identify metabolites of programmed cardio-metabolic dysfunction in breath signatures. Future studies are required to validate the translatability of these findings to humans. PMID- 29593131 TI - [Milk, Daily products and Bone health.Effect of milks and daily products on bone health.] AB - In Japan, nutrition education programs to prevent osteoporosis and osteoporotic fractures have focused primarily on increasing dietary calcium intake and recommended the consumption of milk and dairy products. However, the effect of milk and dairy product consumption on bone density loss or fracture incidence in Japanese has rarely been evaluated in randomized controlled studies. In the present study, we reviewed the literature investigating the consumption of milk and dairy products in relation to bone density and fracture risk. The results showed that milk and dairy product consumption had only a modest effect in the prevention of midlife bone loss and subsequent fractures. However, given that infrequent(once weekly or less)consumption of milk may be associated with an increased risk of femoral neck fracture, and that Japanese generally have a lower calcium intake, it is still necessary to encourage elderly and younger adults to increase their consumption of milk and dairy products to promote bone health. PMID- 29593132 TI - [Milk, Daily products and Bone health.Milk or dairy products and bone:Epidemiology.] AB - An assessment of the association between the intake of milk or dairy products and bone density or the risk of fractures on the basis of epidemiological studies revealed the following findings:(1)a sufficient prepubertal intake of milk or dairy products could contribute to the increased bone growth and maximized peal bone mass because the intake of calcium in the corresponding stage in Japan is inadequate;(2)adequate milk intake could contribute to the maintenance of peal bone mass among menstruating adult females and the decrease of bone loss in postmenopausal females. Adequate milk intake could contribute to the decrease of aging-induced bone loss in elderly males, though there is no sufficient scientific evidence;and(3)a meta-analysis indicated no correlation between the increased milk intake and decreased risks of hip fractures in the elderly. As the intake of milk or dairy products in the Japanese elderly is rather less than that reported by the meta-analysis, the minimal intake of milk or dairy products is anticipated to elevate the risk of fractures in middle-aged or elderly males and females although the scientific evidence is inadequate. PMID- 29593133 TI - [Milk, Daily products and Bone health.Milk, Daily products and Bone health.Dietary Reference Intakes of Calcium by age group.] AB - The amount of calcium in the body changes with age. According to the Dietary Reference Intakes for Japanese(2015), the required amount of calcium is calculated by a factor addition method in consideration of the amount of calcium accumulated in the body, the amount excreted in urine, and percutaneous losses. At that time, the calcium absorption rate becomes a very important factor. Numerical values are set so as to increase the amount of calcium in the body during the growth phase in order to maintain the calcium content in the body after adulthood. Based on the available evidence, the calcium intake level of Japanese is low and needs to be increased. PMID- 29593134 TI - [Milk, Daily products and Bone health.Nutritional Value of Milk and Dairy Products.] AB - Milk has been historically recognized as having great nutritional value;its high nutrient density per energy makes it useful for individuals recovering from malnutrition among others. Milk is composed of an excellent ratio of essential amino acids, with an amino acid score of 100, and enhances the protein content when served with a meal. Additionally, not only is milk rich in calcium, but the absorption rate of calcium contained in the meal increases when milk is served with a meal. Instead of consuming nutritional supplements to make up for a lack of nutrients in the diet, Milk is a representative food that highlights the nutritional value of taking one food in combination with other foods. Moreover, milk costing as little as 100 contains high nutrient density, making it an economically efficient food. PMID- 29593135 TI - [Milk, Daily products and Bone health.Characteristics of calcium in milk.] AB - Milk contains approximately 110mg of calcium per 100mL of milk, a good source of dietary calcium. The calcium in milk comprises of calcium caseinate, micellar calcium phosphate and soluble calcium. It is also reported that the calcium in milk has an excellent bioavailability. Intervention studies of Japanese women have shown that the absorption rate of calcium in milk was greater than that found in small fish and vegetables. Factors taken into account as contributing to higher absorption rates of calcium in milk were:1)the types of calcium present(caseinate, micellar, soluble), 2)the presence of lactose which promotes calcium absorption, and 3)the presence of casein-phosphopeptide which increases soluble calcium fraction. Higher solubility was also observed in the small intestine of rats fed a micellar calcium phosphate casein-phosphopeptide(MCP CPP)complex prepared from milk compared to that in rats fed insoluble whey calcium.

Recent meta-analysis also indicates that beneficial effect of milk and dairy intake on cognitive disorders is significantly observed in Asian population. We have reported that oral administration of milk peptide, CH-3 to AD model mice not only improved cognitive function but also suppressed the expression of inflammatory cytokines and production of oxidative stress. Moreover, administration of other milk proteins improves cognitive function or outcome in AD patients. These findings indicate that milk and dairy intake have possible anti-dementia effects. Further analysis should be necessary to overcome the explosion of dementia worldwide with lifestyle modification. PMID- 29593137 TI - [Milk, Daily products and Bone health.Milk and Dairy Products and "Wasyoku" -"New wasyoku"-.] AB - "Wasyoku;the traditional diets of Japan" refers to foods generally consumed by Japanese people, which is in contrast with the Western diets introduced by Europeans and Americans. The basic Japanese dietary pattern consists of rice as a staple food combined with one soup and two side dishes in a meal, making it easier to achieve a balanced nutritional status. However, salt content tends to be high in "Wasyoku", which negatively affects the overall health of an individual. Recently, Japanese's salt intake has been slowly decreasing;however, a further reduction by approximately 2 g per day is required to prevent hypertension and cardiovascular diseases. To reduce salt intake, while keeping a balanced nutritional status and obtaining adequate amount of energy and nutrients, one should be used to consume a lightly flavored food. However, as Japanese individuals have been accustomed to a high salt diet, which is directly related to a person's good taste or satisfaction level, shifting to lightly flavored foods is extremely difficult. Therefore, one of the methods developed to reduce salt intake is a "New Wasyoku;milk-plus traditional diets of Japan," a recipe utilizing the "koku" or umami taste of milk. The "New Wasyoku" is characterized by adopting to a milk/dairy product-based recipe, which promotes the realization of natural, healthy diets, while maintaining the palatability and nutritional balance of diets. PMID- 29593138 TI - [Milk, Daily products and Bone health.The effect of lactulose on bone health.] AB - Lactulose is a non-digestible oligosaccharide, consisting of galactose and fructose. Bifidobacteria in the large intestine assimilate and metabolize lactulose, which has not been degraded or absorbed by humans, and they subsequently proliferate. Predominant bifidobacteria release short chain fatty acids, such as acetic acid and lactic acid, into the intestinal tract by lactulose metabolization, which lowers the intraluminal pH. As a result, the calcium that has flowed into the large intestine without absorption in the small intestine is solubilized and absorbed in the large intestine. So that means continuous ingestion of lactulose might contribute to bone health by increasing the absorption efficiency of calcium. PMID- 29593139 TI - [Milk, Daily products and Bone health.Milk intake and Bone acquisition in junior high school and high school students.] AB - The junior high school and high school years are the periods during which development spurts occur, and bone mass increases including height and weight. The bone mass gain at this time has a big influence on the maximum bone mass, which also leads to prevention of future osteoporosis. Calcium intake is important for bone mass acquisition, but there is a divergence between the value indicated by the meal intake standard and the actual intake amount, and efforts to increase the calcium intake amount are necessary. From the results obtained by providing milk with school lunch, the significance of drinking milk as a source of calcium at this time is particularly large. PMID- 29593140 TI - [Milk, Daily products and Bone health.Effects of School Lunch Programs on Bone Mass.] AB - In Japan, school lunches are provided to elementary and secondary student, not only for ensuring the intake of well-balanced and nutritious meal, but also hoping to improve their dietary habits. In this article, the authors review the effects of a school lunch program on the bone mass and dietary habits. The school lunch program was divided into 3 groups:a group provided with a complete school lunch, a group provided with only milk supplements, and a group provided with no supplement. The calcaneal bone mass was significantly higher in both primary and the junior high-school students given complete lunches compared with that in the other groups. Moreover, the intake of milk and milk products besides school lunches was more frequent in the groups that received complete lunches. The results suggest that the school lunch program, particularly that providing complete lunches, contributed to increasing the bone mass and improving the dietary habits. PMID- 29593141 TI - [Milk, Daily products and Bone health.School lunch and calcium intake.] AB - The nutritional standard for calcium is set to 50%of the recommended dietary allowance because of the difficulty of obtaining it in the Japanese daily diet. Dairy products, vegetables and pulses were the main sources of calcium in school lunch. The consumption of calcium was significantly higher on the days with school lunches and at lunch. The consumption of calcium in the school lunch has changed the distribution of calcium intake upward, and decreased the number of estimated subjects that were below estimated average requirment. PMID- 29593142 TI - [Milk, Daily products and Bone health.MBPR and bone health.] AB - MBP is a complex of more than 100 basic proteins prepared from bovine milk. It was found that MBP improved the bone metabolism and there are many reports of in vitro studies using osteoblast and osteoclast, animal studies using osteoporosis model and human studies. In human study, oral administration of MBP modulate the balance of bone formation and resorption and improve bone mineral density regardless of age. Research on active component and safety of MBP has been conducted. MBP is used for the variety of commercial foods, such as dairy products, supplements and so on.

PMID- 29593144 TI - Poor toe flexor strength, but not handgrip strength, is associated with the prevalence of diabetes mellitus in middle-aged males. AB - Previous studies suggested that reduced muscular strength was one of the potential predictor of prevalence of diabetes mellitus. The purpose of this study was to investigate the association between toe flexor strength (TFS) and handgrip strength (HGS) and the prevalence of diabetes mellitus. Cross-sectional analysis was conducted using data from 1,390 Japanese males (35-59 years). TFS and HGS were measured and medical examinations undertaken. The prevalence of diabetes mellitus was defined as fasting blood glucose >=126 mg/dL, glycated hemoglobin >=6.5% (48 mmol/mol), and/or current use of anti-diabetes mellitus drugs. A total of 114 participants had diabetes mellitus. TFS in participants with diabetes mellitus was significantly lower than that in persons not suffering from diabetes mellitus but HGS was not. Odds ratio (OR) and 95% confidence interval (CI) per 1 standard deviation-increase in muscular strength measurements for the prevalence of diabetes mellitus were obtained using a multiple logistic regression model. Prevalence of diabetes mellitus was inversely related to TFS (OR 0.769, 95% CI 0.614-0.963), TFS/body mass (BM) (0.696, 0.545-0.889) and TFS/body mass index (BMI) (0.690, 0.539-0.882) after adjustment of covariates. Such associations were not observed in HGS (OR 0.976, 95% CI 0.773-1.232), HGS/BM (0.868, 0.666-1.133) or HGS/BMI (0.826, 0.642-1.062). These results suggested that poor TFS was associated with an increased prevalence of diabetes mellitus independent of visceral fat accumulation, but HGS was not, in middle-aged males. TFS may be a better marker for the prevalence of diabetes mellitus than HGS. PMID- 29593145 TI - Routine Indwelling Urethral Catheterization in Acute Heart Failure Patients Is Associated With Increased Urinary Tract Complications Without Improved Heart Failure Outcomes. AB - BACKGROUND: Indwelling urethral catheters (IUC) are routinely inserted for the purpose of monitoring urine output in patients with acute heart failure (AHF). The benefit of IUC in patients capable of complying with urine collection protocols is unclear, and IUC carry multiple risks. This study describes the impact of IUC on AHF treatment.Methods and Results:A total of 540 records were retrospectively analyzed. After exclusion criteria were applied, 316 patients were propensity matched to establish groups of 100 AHF patients who either did (IUC(+)) or did not receive an IUC (IUC(-)) upon admission. Hospital length of stay (9 vs. 7 days), in-hospital urinary complications (24 vs. 5%), and 1-year urinary tract infection rate (17 vs. 6%; HR, 3.145; 95% CI: 1.240-7.978) were significantly higher in the IUC(+) group (P<0.05 for all). There were no differences in 30-day rehospitalization (6 vs. 6%; HR, 0.981; 95% CI: 0.318 3.058; P=0.986) or major adverse cardiac/cerebrovascular events at 1 year (37 vs. 32%, HR, 1.070; 95% CI: 0.636-1.799; P=0.798). CONCLUSIONS: Based on this retrospective analysis, the routine use of IUC may increase length of stay and UTI complications in AHF patients without reducing the risk for major cardiovascular and cerebrovascular events or 30-day rehospitalization rate. PMID- 29593146 TI - Sex Differences in Long-Term Clinical Outcomes in Patients With Atrial Fibrillation Undergoing Coronary Stent Implantation. AB - BACKGROUND: Patients with concomitant atrial fibrillation (AF) and coronary stenting are at high risk for both cardiovascular and bleeding events. We aimed to evaluate the influence of sex on long-term clinical outcomes in this patient subset.Methods and Results:We identified 1,450 patients with AF and coronary stenting in a patient-level pooled database from 3 Japanese studies, and compared 3-year clinical outcomes between men and women (n=1,075, and n=375, respectively). The cumulative 3-year incidence of all-cause death was significantly higher in women than in men (26.5% vs. 17.2%, log-rank P<0.001), although after adjusting for confounders, the excess mortality risk of women relative to men was no longer significant (hazard ratio (HR): 1.12, 95% confidence interval (CI): 0.85-1.46, P=0.42). There were no significant differences in the adjusted 3-year risks for myocardial infarction or stroke between men and women (HR: 1.25, 95% CI: 0.62-2.40, P=0.52, and HR: 1.15, 95% CI: 0.75-1.74, P=0.52, respectively). However, both the cumulative 3-year incidence of and adjusted risk for major bleeding were significantly higher in women than in men (17.0% vs. 11.3%, log-rank P=0.002, and HR: 1.47, 95% CI: 1.03-2.07, P=0.03). CONCLUSIONS: Among patients with concomitant AF and coronary stenting, there were no significant differences in the adjusted 3-year risks for all-cause death, myocardial infarction, and stroke between men and women. However, women as compared with men were associated with excess adjusted risk for major bleeding. PMID- 29593148 TI - [Rodent associated hantaviruses and hantavirus infections]. AB - Hantaviruses belongs to the genus Hantavirus in the family Bunyaviridae are maintained in rodents and infects to humans by inhalation of the aerosol of infected rodent excreta. In this article, the epidemiology of hantavirus infection and the special relationship between rodent and hantavirus are described. Hantavirus infections include hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS). HFRS is characterized high fever, hemorrhage, and renal disorder. HFRS is distributed in East Asia, Europe, and Russia. While HCPS is characterized acute respiratory dysfunction and cardiogenic shock. The distribution of HCPS is limited in North and South Americas. In Japan's neighboring countries, such as Russia, China, and Korea, large numbers of HFRS patients are reported in association with multiple hantaviruses. In Japan, hantavirus infection has not been reported since 1985 but grey red-backed vole (Myodes rufocanus bedfordiae) inhabiting Hokkaido maintain one of the hantaviruses. Coevolution between hantavirus and host may have been occurred during a long period. The endemic areas of hantavirus infection are strongly associated with the distribution of host animal carrying pathogenic hantaviruses.

MHLW announced ''Special infectious disease prevention guidelines for measles'' (issued on 28 December 2007; Revised issued on 30 March 2013), and Japan decided the elimination target year was fiscal year (FY) 2015. In 2008, it continued to be a large-scale nation epidemic exceeding 10,000 cases, and a large number of 0 to 1 year old infants, teenagers and young adults were suffering. Many cases were unvaccinated, single dose vaccination or unknown vaccination history. The number of measles cases has declined dramatically since 2009, and the measles virus of genotype D5, which was the indigenous strain in Japan, was not detected at the end of May 2010. Regional epidemics were approved in 2011 and 2014, starting from imported cases from overseas, but it ended early. Since 2006, a two-dose routine vaccination regimen of measles rubella combined (MR) vaccine has started, moreover in the 5 years from fiscal 2008, the second dose of MR vaccine for junior high school students and high school students was periodically inoculated and immunization strengthened for teens was done. As a result, antibody positive rate of 95% or more is maintained in all age groups over 2 years old. In March 2015, Japan's measles elimination was certified by the WHO Western Pacific Regional Office. In 2017, outbreaks occurred in adults originating from imported cases from Asia or Europe, but early termination declarations have been made by aggressive measures by local public health centers/institutes. The annual number of reported cases after measles elimination certification is less than 200 cases. PMID- 29593149 TI - [Measles Virus]. AB - Measles virus (MeV) is exceptionally contagious and still a major cause of death in child.However, recently significant progress towards the elimination of measles has been made through increased vaccination coverage of measles containing vaccines. The hemagglutinin (H) protein of MeV interacts with a cellular receptor, and this interaction is the first step of infection. MeV uses two different receptors, signaling lymphocyte activation molecule (SLAM) and nectin-4 expressed on immune cells and epithelial cells, respectively. The interactions of MeV with these receptors nicely explain the immune suppressive and high contagious properties of MeV. Binding of the H protein to a receptor triggers conformational changes in the fusion (F) protein, inducing fusion between viral and host plasma membranes for entry. The stalk region of the H protein plays a key role in the F protein-triggering. Recent studies of the H protein epitopes have revealed that the receptor binding site of the H protein constitutes a major neutralizing epitope. The interaction with two proteinaceous receptors probably imposes strong functional constraints on this epitope for amino acid changes. This would be a reason why measles vaccines, which are derived from MV strains isolated more than 60 years ago, are still highly effective against all MV strains currently circulating.

AB - Members of the genus Emaravirus are plant viruses transmitted by eriophyoid mites. The emaravirus genome consists of multiple, negative-sense, single stranded RNA segments, that have been shown to be highly divergent. Recent studies have revealed that emaraviruses are associated with long-recognized diseases of world important crops such as fig mosaic disease or sterility mosaic disease of pigeon pea. Furthermore, along with the popularization of deep sequencing technologies, new putative members of emaraviruses have been reported year by year. This paper presents an overview of agricultural damages caused by emaraviruses worldwide and characteristics of their genomic RNAs and proteins. In addition, our research project to prevent a disease of a herb crop (shiso, Perilla frutescens) caused by Perilla mosaic virus, a putative emaravirus recently identified in Japan, is outlined.

This review focuses on thevirological significance of processing of HCV core protein by signal peptide peptidase in propagation and pathogenesis of HCV. PMID- 29593154 TI - [Dynamics of the influenza virus genome regulated by cellular host factors]. AB - For efficient replication of the influenza virus genome and its post replicational processes, not only viral factors but also host-derived cellular factors (host factors) are required. The influenza virus genome exists as viral ribonucleoprotein (vRNP) complexes with viral RNA-dependent RNA polymerases and nucleoprotein (NP). Using biochemical and proteomics approaches, we have identified host factors which are required for the vRNP replication and the progeny vRNP transport. We found that MCM complex, a cellular DNA replication licensing factor, is required for successful viral genome replication. In concert with the replication reaction, the nascent RNA chains are encapsidated with NP by cellular splicing factor UAP56. Further, after nuclear export of vRNP, we revealed that vRNP is transported to the plasma membrane using cholesterol enriched recycling endosomes through cell cycle-independent activation of the centrosome by YB-1, which is a mitotic centrosomal protein. Depletion of YB-1 shows that the cholesterol-enriched endosomes are important for clustering of viral structural proteins at lipid rafts to assemble the virus particles concomitantly with the arrival of vRNP beneath the plasma membrane.

AB - Mononegaviruses are non-segmented negative-strand RNA viruses, and include measles, mumps, Marburg, and Ebola viruses. Measles virus and mumps virus, members of the family Paramyxoviridae, are immunotropic and neurotropic, respectively. Marburg virus and Ebola virus, members of the family Filoviridae, cause highly lethal hemorrhagic fever. In this paper, I summarize the recent structural and functional studies on the viral glycoproteins (GPs) of these viruses, which have shed light on virus entry and the humoral response. The structural and functional analyses of the interaction between viral GPs and receptors/antibodies also illuminate directions toward therapeutics against the viruses. PMID- 29593160 TI - Fracture force for veneered materials on restorations measured by torsion testing. AB - The torsional fracture strength at the interface between a base plate and veneering material was evaluated for three kinds of veneered restoration: porcelain fused to zirconia (PFZ), porcelain fused to metal (PFM), and composite resin veneered metal (CRVM). The metal and zirconia base plate (30*4*0.4 mm) were prepared and these plates were veneered as test specimens using each material to a total thickness of 1.2 mm. Torsional force was applied to each specimen using a rotational speed of 1.0 deg/min until the veneering material underwent fracture or exfoliation. The torsional fracture values were measured and the data were statistically analyzed using one-way ANOVA. The torsional fracture strength for PFZ, PFM, and CRVM was 3.0, 3.1, and 11.1 N*cm, respectively. PMID- 29593161 TI - Influence of restorative procedures on endodontically treated premolars: Finite element analysis of a CT-scan based three-dimensional model. AB - An endodontically treated tooth with mesial-occlusal-distal (MOD) cavity is often restored with composite resin. Palatal and buccal cusp reduction (MODP, MODPB), and/or fiber-reinforced composite posts (P), are used in an attempt to improve the longevity of the restoration. The aim of this study was to determine the effects of these procedures on von Mises stress values and distribution in dental tissues and restorative materials using finite element analysis. Based on CT scans of an extracted second upper premolar, six 3D endodontically treated tooth models (MOD, MODP, MODPB, MOD+P, MODP+P, MODPB+P) were created. Each model was subjected to a summary force of 150 N on the occlusal surface simulating the normal biting pattern and maximal von Mises stresses were calculated. MODP seems to reduce von Mises stress values in dental tissues and P seems to transfer some of the stresses from dental tissues to the composite filling. PMID- 29593162 TI - Influence of orthodontic self-etch adhesive on acid resistance of surface enamel. AB - The purpose of this study was to investigate the formation of acid-base resistant zone (ABRZ) of enamel surface during bracket bonding by using three self-etch adhesives presently available in the orthodontic treatment. Also, the relation between the thickness of the ABRZ and bonding strength, the relation between the thickness of the ABRZ and the concentration of fluoride ions contained in the adhesives, were discussed respectively. The ABRZ was formed with all self-etch orthodontic adhesives. ABRZ thicknesses of two self-etch adhesives were approximately 0.8-1.0 MUm, whereas ABRZ thickness of other one was about 0.1 MUm. The bond strengths of all self-etch orthodontic adhesives indicated over 10 MPa, and ABRZ thickness observed in the enamel surface seemed to have no influence to the bond strengths among self-etch adhesives. Moreover, the thickness of ABRZ appeared to be associated with the amount of fluoride ion released from the primer. PMID- 29593163 TI - In vitro evaluation of the cytotoxic activity of three epoxy resin-based endodontic sealers. AB - The aim of the study was to evaluate the cytotoxicity of three epoxy resin-based endodontic sealer, AH Plus, Sicura Seal and Top Seal. Direct and indirect cytotoxicity were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay and LIVE/DEAD(r) Viability/Cytotoxicity Assay on MG63 osteoblasts-like cells. Data were statistically analyzed by analysis of variance and Tukey test, setting a significance level of 5%. Both results related to direct and indirect cell viability tests showed that all groups were significantly more cytotoxic than the negative control group. The cytotoxicity activity after one week of culture showed the absence of direct cytotoxicity, while a medium rate of indirect cytotoxicity. All the three epoxy resin-based sealers (AH Plus, Top Seal and Sicura Seal) showed a medium rate of cytotoxicity on osteoblasts-like cells in vitro. No significant difference was found among the sealers analyzed. PMID- 29593164 TI - Effect of various dimethyl sulfoxide concentrations on the durability of dentin bonding and hybrid layer quality. AB - The objective was to evaluate effect of dimethyl sulfoxide (DMSO) on microtensile bond strength (uTBS) and nanoleakage (NL). Superficial dentin was acid-etched and pretreated with DMSO. Etch-and-rinse adhesive was applied and restored with resin composite incrementally. After 24 h, teeth were sectioned, stored in artificial saliva for 24-h or 6-months before uTBS evaluation. Failure modes were examined. Six beams per group were submitted to nanoleakage evaluation using SEM. Data were analyzed using ANOVA and Tukey's test (alpha=0.05). Pretreatment had no significant effect on uTBS after 24 h (p>0.05). After 6 months storage, uTBS of control decreased significantly, more than with the groups treated with 0.01% or higher (p<0.05). DMSO-pretreated groups preserved uTBS in all groups. After 6 months, all groups except 0.001% showed significantly lower nanoleakege compared to control (p<0.05). DMSO (0.01-20%) may improve the hybrid layer integrity and bonding durability. The best results were seen with low (1-5%) of DMSO concentrations. PMID- 29593166 TI - Erratum. PMID- 29593165 TI - Evaluation of selected mechanical properties of NiTi rotary glide path files manufactured from controlled memory wires. AB - This study aimed to investigate mechanical properties related to flexibility and fracture resistance of controlled memory wiremanufactured nickel-titanium rotary glide path files [HyFlex EDM Glide Path File (EDM) and HyFlex GPF (GPF)]. Scout RaCe (RaCe) served as control. Bending loads, torsional/cyclic fatigue resistance, and screw-in forces were measured. EDM showed a significantly larger torque at fracture, a longer time to cyclic fracture in reciprocation and a larger screw-in force compared with GPF and RaCe. GPF showed significantly lower bending loads and higher angular deflection values than EDM and RaCe, and a significantly longer time to cyclic fracture than RaCe. The time to cyclic fracture was significantly longer in reciprocation compared with continuous rotation in EDM and GPF. It can be concluded that EDM and/or GPF showed higher flexibility and cyclic/torsional fatigue resistance compared with RaCe; and that reciprocation conferred better cyclic fatigue resistance to EDM and GPF. PMID- 29593167 TI - Correlation between clinical severity and type and degree of pectus excavatum in twelve brachycephalic dogs. AB - The aim of the study was to correlate the clinical severity of pectus excavatum with its type and degree based on objective radiographic evaluation. Twelve brachycephalic dogs were included. Grading of the clinical severity was done based on a 6-point grading score. Thoracic radiographs were used to calculate the frontosagittal and vertebral indices at the tenth thoracic vertebra and the vertebra overlying the excavatum. Correlation between the clinical severity score and frontosagittal and vertebral indices was evaluated using Pearson's correlation coefficient. Typical pectus excavatum was recorded in the caudal sternum in seven dogs, with a mean clinical severity score of 1.7 +/- 1.4, whereas in five dogs, atypical mid-sternal deviation was recorded with a mean clinical severity score of 3.8 +/- 0.7. A strong correlation (r=0.7) was recorded between the clinical severity score and vertebral index in the atypical form, whereas a weak correlation (r=0.02) was recorded in the typical form (P<0.05). The clinical severity and degree of pectus excavatum was poorly correlated (r=0.3) in the typical form of pectus excavatum, whereas it was strongly correlated (r=0.9) in the atypical form. Pectus excavatum in dogs is associated with compressive cardiopulmonary dysfunction, which depends mainly on the site/type of deviation rather than the degree of deviation.

AB - BACKGROUND: There are few reports examining regional differences between rural prefectures and metropolitan areas in the management of acute myocardial infarction (AMI) in Japan.Methods and Results:In the Rural AMI registry, a prospective, multi-prefectural registry of AMI in 4 rural prefectures (Ishikawa, Aomori, Ehime and Mie), a total of 1,695 consecutive AMI patients were registered in 2013. Among them, 1,313 patients who underwent primary percutaneous coronary intervention (PPCI) within 24 h of onset were enrolled in this study (Rural group), and compared with the cohort data from the Tokyo CCU Network registry for AMI in the same period (Metropolitan group, 2,075 patients). The prevalence of direct ambulance transport to PCI-capable facilities in the Rural group was significantly lower than that in the Metropolitan group (43.8% vs. 60.3%, P<0.01), which resulted in a longer onset-to-balloon time (OTB: 225 vs. 210 min, P=0.02) and lower prevalence of PPCI in a timely fashion (OTB <=2 h: 11.5% vs. 20.7%, P<0.01) in the Rural group. Multivariate analysis revealed that direct ambulance transport was the strongest predictor for PPCI in a timely fashion (odds ratio=4.13, P<0.001). CONCLUSIONS: AMI patients in rural areas were less likely to be transported directly to PCI-capable facilities, resulting in time delay to PPCI compared with those in metropolitan areas.

PMID- 29593171 TI - Can intraoperative kinematic analysis predict postoperative kinematics following total knee arthroplasty? A preliminary. AB - The preliminary study analyzed the relationship between intraoperative navigation based kinematics and postoperative 2-dimensional/3-dimensional (2D/3D) image registration-based kinematics in total knee arthroplasty (TKA). Six knees in 5 patients were analyzed. All TKA procedures were performed using an image-free knee navigation system. Tibial internal rotation was assessed by intraoperative knee kinematics. At 1 year after surgery, tibial internal rotation was evaluated using a 2D/3D image registration technique under loaded and unloaded conditions. The correlation between intraoperative and postoperative data for the tibial internal rotation angle at 10 increments of knee flexion was then assessed. Difference in the knee flexion angle between the intraoperative and postoperative evaluations was adjusted to account for the sagittal cutting angle of the distal femur and proximal tibia. A correlation was found between the intraoperative and postoperative data for loaded knee flexion with this adjustment (Pearson's r = 0.725, p = 0.012). However, intraoperative kinematics was not significantly correlated with postoperative kinematics in the absence of loading. Larger adequately powered prospective studies are now needed to confirm our preliminary finding that postoperative loaded kinematics can be predicted by intraoperative evaluation. J. Med.

AB - AIM: Shift workers have a high risk of cardiovascular disease (CVD). Systemic inflammation measured has been associated with the risk of CVD onset, in addition to classical risk factors. However, the association between work schedule and inflammatory cytokine levels remains unclear. The purpose of this study was to examine the association between work schedule and interleukin-6 (IL-6)/high sensitivity C-reactive protein (hs-CRP) levels among Japanese workers. METHODS: The present cross-sectional study was a part of the Japanese Study of Health, Occupation and Psychosocial Factors Related Equity (J-HOPE). A total of 5259 persons who measured inflammatory cytokine were analyzed in this study. One-way analysis of variance was used to test log-transformed IL-6/hs-CRP differences by work schedule. Multiple regression analysis was used to examine the difference adjusted for other possible CVD risk factors. RESULTS: There were 3660 participants who had a regular work schedule; the remaining schedules were shift work without night work for 181 participants, shift work with night work for 1276 participants, and only night work for 142 participants. The unadjusted model showed that only night workers were significantly related to high levels of IL-6 compared with regular workers. Even in the multiple regression analysis, the higher level of IL-6 among only night workers remained significant (beta=0.058, P=0.01). On the contrary, hs-CRP was not. CONCLUSION: The present study revealed that only night shift work is significantly associated with high levels of IL-6 in Japanese workers. These observations help us understand the mechanism for the association between work schedule and CVD onset. PMID- 29593173 TI - [Evaluation of Dissolution Profiles of Famotidine from OTC Drugs]. AB - In recent years, self-medication has started to receive more attention in Japan owing to increasing medical costs and health awareness among people. One of the main roles of pharmacists in self-medication is to provide appropriate information regarding OTC drugs. However, pharmacists promoting the proper use of OTC drugs have little information on their formulation properties. In this study, we performed dissolution tests on both OTC drugs and ethical drug (ED) containing famotidine, and evaluated the differences in their dissolution profiles. Marked differences in dissolution profiles of OTC drugs were observed in test solutions at pH 1.2, 4.0, and 6.8 and in water. To evaluate the differences quantitatively, we calculated the lag time and dissolution rate constant from the dissolution profiles. Significant differences in lag times and dissolution rate constants between some OTC drugs and ED were observed. We also used similarity factor (f2), to quantify the similarity between dissolution profiles of OTC drugs and ED. f2 values less than 42 were observed in some OTC drugs, suggesting that these differences might influence absorption in vivo resulting in differences in their onset time and efficacy. The findings of this study will provide useful information for the promotion of proper use of OTC drugs. PMID- 29593174 TI - Cytotoxic Lathyrane-Type Diterpenes from Seeds of Euphorbia lathyris. AB - We isolated two new lathyrane-type diterpenes L27 (1) and L28 (2) along with seven known compounds (3-9) from the seeds of Euphorbia lathyris. These compounds were identified by NMR, high-resolution electrospray ionisation (HR-ESI)-MS as well as IR spectroscopy. Compounds 1 and 2 were assigned NMR spectrums with 1H NMR, 13C-NMR, distortionless enhancement by polarization (DEPT), correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond connectivity (HMBC) and nuclear Overhauser effect spectroscopy (NOESY). Stereo configuration of 1 and 2 were confirmed by comprehensive interpretation of their nuclear Overhauser effect (NOE) relationship and showed they were first natural lathyrane-type diterpenes possessing alpha-configuration substitutes at C-3. Cytotoxicity assay of isolated compounds were evaluated against breast cancer cell lines MCF-7 or MDA-MB-231, 786-0 and liver cancer cell lines HepG2. As a result, Euphorbia factor L28 (2) showed strongly cytotoxicity to the 786-0 and HepG2 cell lines, with an IC50 value of 9.43 and 13.22 uM, respectively, which preliminarily suggested that the configuration of lathyrane-type diterpene at C-3 has a significant effect on its bioactivity. PMID- 29593175 TI - Neopterin and Cardiovascular Events Following Coronary Stent Implantation in Patients with Stable Angina Pectoris. AB - AIM: Neopterin is an activation marker for monocytes/macrophages. We prospectively investigated the predictive value of plasma neopterin levels on 2 year and long-term cardiovascular events in patients with stable angina pectoris (SAP) undergoing coronary stent implantation. METHODS: We studied 123 consecutive patients with SAP who underwent primary coronary stenting (44 patients with bare metal stent: BMS group and 79 with drug-eluting stent: DES group). Plasma neopterin levels were measured on admission using HPLC. Moreover, one frozen coronary artery specimen after DES and three frozen coronary specimens after BMS were obtained by autopsy or endarterectomy, followed by immunohistochemical staining for neopterin. RESULTS: Plasma neopterin levels were significantly higher in patients with cardiovascular events than in those without them (P<0.001). In subgroup analyses, higher levels of plasma neopterin in patients with cardiovascular events (P<0.001) and a positive correlation between neopterin levels and late lumen loss after stenting (P =0.008) were observed in the BMS group but not in the DES group (P=0.53 and P=0.17, respectively). In long-term cardiovascular events, multivariate Cox regression analysis identified the significance of the high-neopterin group as independent determinants of cardiovascular events (hazard ratio, 2.225; 95% CI, 1.283-3.857; P =0.004). Immunohistochemical staining showed abundant neopterin-positive macrophages in the neointima after BMS implantation but no neopterin-positive macrophages in the neointima after DES implantation. CONCLUSION: These findings suggest that neopterin is associated with cardiovascular events after coronary stent implantation in patients with SAP. However, there might be a strong association between neopterin and cardiovascular events after BMS but not after DES in these patients. PMID- 29593176 TI - [Structure of Relationships Formed by Occupational Health Nurses for Co-operating with Managers to Support Workers with Mental Health Concerns]. AB - OBJECTIVE: Occupational health staff and managers play important roles in supporting workers with mental health concerns and mutual co-operation among them is a necessary element. However, when co-operating with other professionals, several problems arise that often make such co-operation a challenge. Effective mutual actions are needed to promote such co-operation, and relationships must be formed for this purpose. Therefore, in this study, we aimed to clarify how occupational health nurses form relationships for facilitating co-operation with managers to provide support to workers with mental health concerns. METHODS: Data were collected using semi-structured interviews with 11 occupational health nurses who provide individualized mental health support and who have at least 5 years of experience as occupational health nurses. Analysis of the recorded interviews was performed using a qualitative statistical method (KJ method). RESULTS: Six elements that constitute the formation of relationships were identified. When occupational health nurses form relationships for facilitating co-operation with a manager to provide support to workers, they "form relationships through strategic communication" with them and when co-operation is required, they form a relationship by "acting in a manner that suits the manager," such as his/her character and the situation. To support this relationship, occupational health nurses "provide mental support to the manager" by listening to his/her anxiety or real intention about supporting the subordinate with mental health concerns and provide relief while understanding their burdens during the co-operation. Occupational health nurses even "provide support to the manager in their activities," which assessed the situation at the workplace as the specialist and advised the manager to understand how to concern to the subordinate specifically. In addition, they "indirectly support the manager" which included coordinating with the concerned persons so as to not excessively burden the manager. Such support promoted the "creation of systems for clear roles" of managers in supporting the subordinate with mental health concerns. DISCUSSIONS: Relationships that occupational health nurses form with their managers were the structure which formed emotional human relationships from the front or back necessity of co-operation causes and developing confidence in relationships with the foundation of emotional human relationships. PMID- 29593177 TI - Molecular Pathogenesis of Familial Wolff-Parkinson-White Syndrome. AB - Familial Wolff-Parkinson-White (WPW) syndrome is an autosomal dominant inherited disease and consists of a small percentage of WPW syndrome which exhibits ventricular pre-excitation by development of accessory atrioventricular pathway. A series of mutations in PRKAG2 gene encoding gamma2 subunit of 5'AMP-activated protein kinase (AMPK) has been identified as the cause of familial WPW syndrome. AMPK is one of the most important metabolic regulators of carbohydrates and lipids in many types of tissues including cardiac and skeletal muscles. Patients and animals with the mutation in PRKAG2 gene exhibit aberrant atrioventricular conduction associated with cardiac glycogen overload. Recent studies have revealed "novel" significance of canonical pathways leading to glycogen synthesis and provided us profound insights into molecular mechanism of the regulation of glycogen metabolism by AMPK. This review focuses on the molecular basis of the pathogenesis of cardiac abnormality due to PRKAG2 mutation and will provide current overviews of the mechanism of glycogen regulation by AMPK. J.

AB - Geranylgeranylacetone (GGA) is a chaperon inducer that protects various types of cell and tissue against stress. We examined whether GGA modulated energy intake and expenditure under stressful conditions. After mice were untreated or treated orally with GGA (0.16 g per kg body weight per day) for 10 days, they were subjected to 2-h restraint stress once or once a day for 5 consecutive days. GGA administration did not affect corticosterone response to the stress. Restraint stress rapidly decreased plasma leptin levels in control mice. GGA significantly increased circulating leptin levels without changing food intake and prevented the stress-induced decline of circulating leptin. However GGA-treated mice significantly reduced food intake during the repeated stress, compared with control mice. GGA prevented the stress-induced decline of leptin mRNA and its protein levels in epidydimal adipose tissues. We also found that GGA decreased ghrelin mRNA expression in gastric mucosa before the stress, whereas GGA-treated mice recovered the ghrelin mRNA expression to the baseline level after the repeated stress. Leptin and ghrelin are now recognized as regulators of anxiety and depressive mood. Our results suggest that GGA may regulate food intake and relief stress-induced mood disturbance through regulating leptin and ghrelin secretions. J. Med. Invest. 65:103-109, February, 2018. PMID- 29593179 TI - Virological characterization of HIV-1 CA-NTD mutants constructed in a virus lineage reflected manner. AB - Capsid (CA) protein is a major virion-constituent of all retroviruses including human immunodeficiency virus type 1 (HIV-1), and is essential for early and late phases in viral replication cycle through interaction with numerous cellular factors. In particular, N-terminal domain (NTD) of HIV-1 CA has been frequently and well reported to bind to various host cell proteins that considerably affect viral replication potential. In this study, in order to better define biological bases of the CA-NTD for HIV-1 replication, we performed an extensive mutational analysis in an unprecedented manner. By aligning CA-NTD sequences derived from representative infectious molecular clones of HIV-1, HIV-2, and simian immunodeficiency virus isolated from the rhesus macaque (SIVmac), a number of amino acids specific to HIV-1 were selected, and were replaced with those from SIVmac at the corresponding sites. Mutant viruses thus generated were then examined for multi-cycle infectivity, single-cycle infectivity, and ability to produce progeny virions. While some CA-NTD mutations affected viral replication ability to varying degrees, those in helix 7 abolished viral growth potential without exception. These results highlight functional importance of non-conserved amino acids in helix 7, and give new insights into functionality of HIV-1 CA-NTD. J. Med. Invest. 65:110-115, February, 2018. PMID- 29593180 TI - The ratio of contrast medium volume to estimated glomerular filtration rate as a predictor of contrast-induced nephropathy after endovascular aortic repair. AB - OBJECTIVE: This study aimed to determine the perioperative predictors of contrast medium-induced nephropathy (CIN) after endovascular aortic repair (EVAR). MATERIALS AND METHODS: The data of 203 consecutive patients who underwent elective EVAR for thoracic and abdominal aortic aneurysm between January 2014 and September 2014 were retrospectively analyzed. CIN was defined according to the diagnostic criteria of the European Society of Urogenital Radiology. RESULTS: Fourteen patients (6.9%) developed CIN after EVAR. Contrast medium volume (CV), preoperative serum creatinine, estimated glomerular filtration rate (eGFR), and the CV/eGFR ratio were significantly related with CIN development after EVAR. The CV/eGFR ratio was significantly higher in patients with CIN than those without CIN. Receiver operator characteristic curve analysis showed that the area under the curve of the CV/eGFR ratio was 0.782, indicating that it was the most important predictor. The appropriate CV/eGFR ratio cutoff was 1.62. Sensitivity and specificity were 85.7% and 65.6%, respectively. CONCLUSIONS: The CV/eGFR ratio was a useful predictor of contrast medium-induced nephropathy after EVAR. It is possible that the score can be used in patients when managing the EVAR techniques and contrast medium volume. J. Med. Invest. 65:116-121, February, 2018. PMID- 29593181 TI - Skeletal muscle mass of old Japanese women suffering from walking difficulty in nursing home. AB - By using 24 hour urinary creatinine levels, skeletal muscle mass (kg), its rate (%) of body weight and creatinine height index (%) were determined in old Japanese women suffering from walking difficulty in nursing home and compare with those of young university students. Those of old subjects showed approximately 30 50%, 36-44% and 44-46% of young subjects, respectively. It is suggested that these values are important and useful biomarkers for the planning and the achievement of rehabilitation program for the maintaining and restoring skeletal muscle mass and for the careful support by registered care workers to aged persons.

PMID- 29593182 TI - High defect stage, contralateral defects, and poor flexibility are negative predictive factors of bone union in pediatric and adolescent athletes with spondylolysis. AB - PURPOSE: To identify predisposition to spondylolysis and physical characteristics associated with "bone union" following conservative spondylolysis treatment among pediatric and adolescent athletes. METHODS: We retrospectively analyzed pediatric and adolescent athletes with spondylolysis who underwent conservative treatment and rehabilitation for three or more consecutive months following sports activity cessation. Patients with terminal spondylolysis or who did not discontinue sports activities were excluded. We compared physical fitness factors in the union and nonunion groups and examined the association between bone union and spondylolysis severity by logistic regression analysis. RESULTS: Of 183 patients with spondylolysis who underwent rehabilitation over a four-year period, 127 patients with 227 defects were included in the final analysis. Bone union was achieved in 66.5% (151/227) of the pars interarticularis defects and 70.1% (89/127) of the patients. On multivariate analysis, stage of pars interarticularis defect (odds ratio [OR], 0.26;p = 0.0027), stage of contralateral pars interarticularis defect (OR, 0.51;p = 0.00026), and straight leg-raising test (OR, 1.06;p = 0.028) were significantly associated with bone union. CONCLUSIONS: High defect stage, stage of the contralateral pars interarticularis defect, and poor flexibility were negative prognostic factors of bone healing in athletes with spondylolysis. J. Med.

AB - Clostridium difficile (C. difficile)-associated diarrhea (CDAD) is a challenging nosocomial infectious disease. C. DIFF Quik Chek Complete assay is widely used to detect glutamate dehydrogenase (GDH) antigen and toxin A/B of C. difficile simultaneously. However, the interpretation of GDH positive/toxin negative results is problematic. We performed a retrospective study of patients with GDH positive/toxin negative results to determine the probability of detecting toxigenic C. difficile and its risk factors. Between April 2012 and March 2017, we investigated cultures of fecal specimens followed by toxin detection tests. The clinical histories of patients with and without toxigenic C. difficile were compared using univariate- and multivariate-analyses. In total, 2675 patients were examined using C. Diff Quik Chek Complete assay. Among 356 GDH positive/toxin negative patients, cultures were performed in 220 cases and toxigenic C. difficile was recovered from 139 (63.2%) specimens. Patients with toxigenic C. difficile had significantly lower body mass index than those without. Over half the GDH positive/toxin negative patients were infected with toxigenic C. difficile. Lower BMI was a CDAD risk factor in this patient population. These data can be utilized to initiate isolation and clinical interventions before confirmatory test results are available. J. Med.

PMID- 29593185 TI - Effectiveness of using non-invasive continuous arterial pressure monitoring with ClearSight in hemodynamic monitoring during living renal transplantation in a recipient:a case report. AB - We investigated the effectiveness of the ClearSight system for hemodynamic management during kidney transplantation for a recipient. The recipient was to receive a kidney transplant from his mother under general anesthesia. We used continuous noninvasive finger-cuff-based monitoring of blood pressure, provided by the ClearSight system, and stroke volume variation to predict fluid responsiveness. We used of a balanced anesthetic technique and stringent monitoring standards to ensure a successful outcome for the patient. This case demonstrated that ClearSight has the potential to improve patient monitoring in hemodynamically stable patients who received kidney transplantation under general anesthesia. J. Med.

AB - Herein, we describe the operative procedure for combined resection of re recurrent lateral lymph nodes and the external iliac vein. There is no consensus on the clinical implications of resection of locally re-recurrent colorectal tumors, as the operative procedure is extremely difficult. We present the case of a 52-year-old woman who underwent abdominoperineal resection. About one year later, we excised a recurrent lymph node in the left lateral obturator area through an extraperitoneal approach. About 18 months later, lymph node re recurrence in the left external iliac area was observed. Re-recurrent lymph nodes directly invade the left external iliac vein. We removed the re-recurrent lymph node with combined, radical segmental resection of the left external iliac vein, left obturator artery and vein, and left obturator nerve. J. Med.

AB - We report the case of a 77-year-old man who presented to our hospital with cecal cancer, lung metastasis, and liver metastasis in January 2013. After four courses of modified infusional intravenous fluorouracil and levofolinate with oxaliplatin (mFOLFOX 6) + bevacizumab, there was no new metastatic lesion and lung metastasis reduction was observed. Ileocecal resection was performed in May, left lower lung lobectomy in August, and extended right posterior segmentectomy + S8 partial liver resection was performed in December. The tumor marker declined initially;thereafter, it gradually increased. Computed tomography (CT) performed in April 2014 revealed right inguinal mass around the mesh-plug prosthesis. A positron emission tomography-CT (PET-CT) also revealed a high 2-fluoro-2-deoxy-D glucose (FDG) uptake at the same site. Right inguinal tumor resection was performed in July. Cancer tissues were confirmed by performing intraoperative rapid pathological diagnosis, and R0 resection could be achieved. Previous studies have reported malignant tumor metastases to the mesh-plug prosthesis, and this was believed to one of the sites that cancer cells can easily engraft. In particular, in patients with a history of advanced malignant tumors, if mass formation around the artifact insertion site is observed, the possibility of peritoneal metastasis should be considered.

AB - A 65-year-old female had been treated rheumatoid arthritis (RA), interstitial pneumonia (IP) and nephrotic syndrome with prednisolone and cyclosporine. She was emergently admitted to our hospital due to the worsening exertional dyspnea and severe hypoxemia. Chest computed tomography (CT) showed new diffuse ground-glass opacities (GGOs) with slight consolidations along with bronchovascular bundle were observed in addition to pre-existing reticular shadows in both lungs with lower lobe-predominance. An acute exacerbation (AE) of pre-existing IP triggered by an infection was suspected, and the treatment with antibiotics and corticosteroid pulse therapy improved her general condition and chest radiological findings. Because some auto-antibodies associated with acute/subacute onset IP have recently become available in clinic, we examined those including anti-aminoacyl tRNA synthetase (ARS) antibodies, and found that she was positive for anti-PL-7 antibody. We diagnosed her anti-synthetase syndrome (ASS) without symptom of myositis, and her IP was considered to be ASS related. The careful consideration is necessary to precisely diagnose and treat the patients with RA-associated interstitial lung diseases as the several etiologies may be overlapped in the same patient. J.

AB - OBJECTIVE: Individuals with CP have a lower life expectancy than the general population. The objective of the study is to investigate the risk factor of mortality in Indonesian children with CP. METHODS: An observational analytic study was conducted using medical records at pediatric ward Dr. Soetomo Hospital, Surabaya, Indonesia, from January 2014 to December 2016. Inclusion criteria was all of CP patients in that were hospitalized from 6 months to 14 year of age. Mortality information was obtained from annual computer and matched against the subjects with CP on the basis of name, date of birth, type of disability, degree of disability, nutritional status and the outcomes. Risk factors were counted using logistic regression. RESULT: Fifty five children were enrolled. The outcome revaled 12 patients (21.8%) were death. Pneumonia was the most common underlying disease cause of death (OR=5.185;95% CI 1.249 to 21.520;Psize 8 < 0.007). Other risk factors of mortality that significant were acute kidney injury (AKI) (OR=3.333;95% CI 1.317 to 8.436;Psize 8 < 0.03). and Gross Motor Functioning Classification System (GMFCS) more than level IV (OR=1.480;95% CI 1.184 to 1.850;Psize 8 < 0.006). CONCLUSION: Pneumonia, AKI and severe GMFCS level were risk factors of death in patients with CP. J. Med. Invest. 65:18-20, February, 2018. PMID- 29593189 TI - Results of Hepatic Resection for Liver Metastasis of Gastric Cancer. AB - BACKGROUND: Surgical indication for hepatic resection is controversial in gastric cancer liver metastasis (GLM). The aim of this study is to clarify the effect of hepatic resection for GLM. METHODOLOGY: Ten patients who underwent hepatic resection for GLM between 2001 and 2013 were enrolled in this study. Six patients underwent synchronous hepatic resection and gastrectomy, and the remaining four patients underwent metachronous hepatic resection. Six patients had solitary liver metastasis, and 4 patients had multiple liver metastasis. The median follow up period was 12.4 months (the range being 0.5 months to 50 months). RESULT: The actual 1- year and 3-year overall survival rates for the patients who underwent hepatic resection are 88.9% and 17.8%, respectively. The median survival time was 21.5 months. And the 1-year recurrence free survival time was 20.0%. The median recurrence free survival rate was 4.7 months. Regarding post-operative recurrence, synchronous hepatic resection tended to be a recurrence factor (p=0.08). CONCLUSION: Hepatic resection for GLM has an acceptable outcome. Metachronous hepatic resection tends to have a better outcome than synchronous hepatic resection for the treatment of GLM. J. Med. Invest. 65:27-31, February, 2018. PMID- 29593190 TI - Administration of Kampo medicine through a tube at an advanced critical care center. AB - n emergency and critical care medical centers, tube administration is employed for patients who have difficulty swallowing oral drugs owing to decreased consciousness or mechanical ventilation. However, tube clogging due to drug injection is a concern. We compared the crushing method with the simple suspension method for the passage of amlodipine, an antihypertensive drug, in combination with rikkunshito, which has been used to treat upper gastrointestinal disorders such as functional dyspepsia and gastroesophageal reflux in emergency and critical care medical centers, to ascertain the effect of Kampo products on the passage of other drugs during tube administration. When the crushing method was employed, poorly water-soluble solid products were formed, while a uniformly dispersed suspension was obtained using the simple suspension method. In addition, the passage rate of amlodipine through the tube was 64% and 93% in the crushing and simple suspension methods, respectively, thereby indicating that the simple suspension method provided more favorable than the crushing method. The results of this study suggested that the passage rate of amlodipine for patients who received Kampo products concurrently was higher when the simple suspension method was used, and an appropriate drug amount might well be able to administered to patients using this method.

AB - BACKGROUND: The treatment strategy for jaundiced patients with hilar cholangiocarcinoma (HC) is not well established. In this study, we evaluate the feasibility of our perioperative protocol for jaundiced patients with HC. METHODS: Twenty patients with HC who underwent hepatic resection at our institute were enrolled, and patients were divided into icteric(n=6) and normal(n=14) group. As a perioperative protocol, Oral administration of Inchinkoto(ICKT), steroid and nafamostat mesilate were introduced. The evaluation of functional future remnant liver(FRL) by asiaroscintigraphy, and postoperative outcomes were retrospectively compared. RESULTS: Indocyanine green dye retention rate at 15 minutes was higher, and LHL15 values was lower in icteric group. However, in the functional evaluation of FRL, which was the sum of GSA uptake of the future FRL, there was no significant difference of LHL15 values of the remnant liver functional reserve between the two groups. As results, according to the difference of liver function, serum AST level was not different between two groups. The number of patients with postoperative morbidity in the two groups was comparable. CONCLUSIONS: Even in HC patients with icteric liver, accurate assessment of liver functional reserve and effective perioperative treatment may attribute to successful hepatectomy and favorable post-operative outcomes.

AB - Tapioca milk tea, the most popular beverage in Taiwan, is consumed a lot by Taiwanese which contributed to their daily sugar intake. Our study purpose is to investigate whether limiting intake of tapioca milk tea is useful for the control of sugar intake in Taiwanese. The study was conducted in questionnaires selected 38 subjects, 20-24 y, from 341 university students in Kaohsiung City, Taiwan. Subjects were match-paired by sex, age, department, and randomly divided into two groups for cross-over design in which each group had 1 week with or without tapioca milk tea. Other beverages and foods were allowed freely in both periods. Each group member recorded their own daily sugary intake for two weeks and was confirmed by researchers the next day. The average sugar intakes with or without tapioca milk tea were similar between the two treatments (p 0.05), 58.4 23.2 g/day and 56.5 22.2 g/day (glucose 25%, fructose 19%, sucrose 53%, lactose 3%). With or without tapioca milk tea, 85% of sugar intakes came from beverages. Even by limiting tapioca milk tea, the subjects took the same sugar amount from other beverages, suggesting that an established sugar intake level is hard to change. J. Med.

AB - Refeeding syndrome (RFS) is characterized by the metabolic and clinical changes that occur following aggressive nutritional supplementation in malnourished patients. Hypophosphatemia is the hallmark of RFS and is key to its prevention and treatment in clinical practice. However, the mechanism of hypophosphatemia during RFS is unclear because of the lack of an animal model. In this study, we developed a rat RFS model as a first step to clarifying the molecular mechanism. After establishing the parenteral route, rats were fasted for 5 days and refeeding was started using total parenteral nutrition. The animals were infused with a high calorie solution with or without insulin administration. Results showed that plasma phosphate levels did not decrease in rats infused with the high calorie solution alone;in contrast, a 20% reduction compared to baseline was observed in rats administered insulin. In addition, rats infused with the high calorie solution containing added phosphate did not present with hypophosphatemia. Thus, we developed a rat RFS model with hypophosphatemia by tube feeding and insulin administration, and demonstrated the importance of phosphate in preventing refeeding hypophosphatemia. J. Med.

AB - Low back pain (LBP) often occurs in baseball players;however, the characteristics of the location of their LBP with respect to their throwing and hitting sides have not been clarified. In order to clarify the left-right asymmetry of LBP that occurs in baseball players, we surveyed 247 university baseball players using an LBP questionnaire. The main investigational items were:throwing and hitting side, position at the time of LBP experience, and LBP location. Based upon the indication of their throwing and hitting side, subjects were classified into unilateral rotational (UR) or bilateral rotational (BR) types. Subjects were also classified into categories of LBP location as described by ipsilateral or contralateral to dominant side of throwing or hitting. Chi-square test or Fisher exact test were used to compare LBP location side by rotational type (UR/BR) in all subjects and by position (pitcher/fielder). We found that among fielders, LBP occurring contralateral to the hitting side in UR was significantly more frequent than that in BR. We conclude that LBP occurred in baseball fielders with a left right asymmetry, which suggests that high frequency unilateral rotation causes the lumbar region contralateral to the dominant hitting side to be subject to a high load.

AB - AIM: To evaluate the anatomical changes in the ciliary body (CB) during naturally stimulated accommodation in children using anterior segment optical coherence tomography (OCT). METHODS: This study was a prospective, observational, noncomparative case series included 18 eyes of 9 children (8 males and 1 female) aged from 4 to 10 years. Ciliary body thickness (CBT) was measured temporally by Anterior OCT at 1, 2 and 3 mm posterior to the scleral spur. Measurements were performed in the accommodated state and the unaccommodated state (with cycloplegia). RESULTS: The mean CBT significantly increased by accommodation at 1 mm posterior to the scleral spur from 751 42 to 818 40 MUm (P 0.001) and significantly decreased at 2 and 3 mm from 506 66 to 445 59 MUm and from 290 54 to 240 50 MUm respectively (P 0.001). CONCLUSION: During accommodation, the anterior portion of the ciliary body thickens, while the posterior portion decreases in thickness. These findings imply that the circular ciliary muscles are mainly involved in accommodation and not the longitudinal muscles. J. Med. Invest. 65:60-63, February, 2018. PMID- 29593196 TI - The plasma level changes of VEGF and soluble VEGF receptor-1 are associated with high-altitude pulmonary edema. AB - Hypoxia-induced plasma levels of VEGF and sFlt-1 are responsible for increased vascular permeability occurred in both brain and pulmonary edema. Currently, it remains unclear the exact roles of VEGF and sFlt-1 in High Altitude Pulmonary Edema (HAPE) pathogenesis. In this study, plasma levels of VEGF and sFlt-1 from 10 HAPE and 10 non-HAPE subjects were measured and compared. The results showed that plasma levels of both VEGF and sFlt-1 in HAPE patients were significantly increased as compared to the non-HAPE group. Interestingly, increased plasma levels of these two protein factors were markedly reduced after treatments. As compared to VEGF, sFlt-1 was much more affected by hypoxia and treatments, suggesting this factor was a key factor contributed to HAPE pathogenesis. Importantly, the ratio of sFlt-1 and VEGF in group of either non-HAPE or HAPE after recovery was significantly lower than the ratio in HAPE patients prior to treatments. Our findings suggested that sFlt-1 was a key factor that involved in HAPE pathogenesis and the sFlt-1/VEGF ratio could be used as a sensitive diagnostic marker for HAPE. J. Med.

AB - Robot-assisted laparoscopic radical prostatectomy (RALRP) is commonly performed in the surgical treatment of prostate cancer. However, the steep Trendelenburg position (25) and pneumoperitoneum required for this procedure can sometimes cause hemodynamic changes. Although blood pressure is traditionally monitored invasively during RALRP, the ClearSight system (BMEYE, Amsterdam, The Netherlands) enables a totally noninvasive and simple continuous blood pressure and cardiac output monitoring based on finger arterial pressure pulse contour analysis. We therefore investigated whether noninvasive continuous arterial blood pressure measurements using the ClearSight system were comparable to those obtained invasively in patients undergoing RALRP. Ten patients scheduled for RALRP with American Society of Anesthesiologists physical status I-II were included in this study. At each of the seven defined time points, noninvasive and invasive blood pressure measurements were documented and compared in each patient using Bland-Altman analysis. Although the blood pressure measured with the ClearSight system correlated with that measured invasively, a large difference between the values obtained by the two devices was noted. The ClearSight system was unable to detect blood pressure accurately during RALRP, suggesting that blood pressure monitoring using this device alone is not feasible in this small patient population.

PMID- 29593198 TI - Associations between intake of dietary fermented soy food and concentrations of inflammatory markers: a cross-sectional study in Japanese workers. AB - Epidemiological investigations have shown that consumption of soybeans or soy foods reduces the risk of the development of cardiovascular disease, cancer and osteoporosis. The aim of this study was to determine the associations between different soy foods and inflammatory markers, including high-sensitivity C reactive protein (hs-CRP), interleukin (IL)-6, and IL-18, in Japanese workers. The cross-sectional study included 1,426 Japanese workers (1,053 men and 373 women) aged 20 to 64 years. Intake of 12 soy foods was estimated by a validated food frequency questionnaire. Associations of total soy foods, fermented soy food, non-fermented soy food, soy isoflavone with hs-CRP, IL-6, and IL-18 levels were examined by general linear model regression analysis. We found that total fermented soy food intake was inversely associated with multivariable-adjusted geometric concentration of IL-6 in men (Q1:1.03 pg/mL, Q5:0.94 pg /mL;P for trend = 0.031). Furthermore, it was shown that IL-6 concentrations were inversely associated with miso intake (beta = -0.068;p = 0.034) and soy sauce intake in men (beta = -0.074;p = 0.018). This study suggests that intake of total fermented soy food, miso and soy sauce be associated with IL-6 concentrations in Japanese men. J. Med. Invest. 65:74-80, February, 2018. PMID- 29593199 TI - Falls among Hospitalized Patients in an Acute Care Hospital: Analyses of Incident Reports. AB - Falls cause injuries such as fractures, skin lacerations, bleeding, and head injury, and could result in more severe medical conditions in hospitalized patients. We retrospectively investigated the incidence and characteristics of falls among hospitalized patients in an acute care hospital from incident reports by hospital staff between January and June 2013. There were 154 falls in 135 patients, 2 of which resulted in fracture. The average age of patients who fell was 63.9 (range 0 to 91) years. Many falls occurred at the bedside (68.2%). Approximately half of all falls were related to elimination (46.6%). The most common time of discovery of falls was 2:00-2:59 AM (14/154;9.1%), followed by early in the morning when patients would actively move. Fall rates in our hospital were 1.39 falls per 1,000 patient days. The department of respiratory medicine and rheumatology had the highest fall rate (3.08 falls per 1,000 patient days), followed by the departments of neurosurgery and neurology (2.98 falls per 1,000 patient days). This study revealed the characteristics of falls in an acute care hospital, and suggests that their notification in the hospital might help reduce the incidence of falls in hospitalized patients. J.

AB - Ligamentum flavum (LF) hypertrophy is one of the main factors of lumbar spinal canal stenosis (LSCS). The primary object of this study is to clarify the existence of epiligament in the LF and its role in hypertrophy, and to develop an LF hypertrophy animal model. A cadaveric spine from a 30-year-old man was used to investigate the existence of epiligament in LF. Five LF samples from LSCS patients were obtained to evaluate hypertrophied LF. To create a rat model, we destabilized the lumbar spine. Each LF was sagittally cut for histological evaluation. The epiligament was clearly evident in normal LF specimens, which stained pink on Elastica van Gieson and green on Masson Trichrome. One layer was observed on the dural side and another on the dorsal side of the LF. LSCS patients had an enlarged dorsal epiligament, at around 30 times that of the regular thin epiligament on the dural side. The destabilized rat model showed an enlarged dorsal epiligament, with a mean thickness 8-fold that of the control. LF hypertrophy may be due to enlargement of the dorsal epiligament. Mechanical loading of the LF is an important factor for inducing hypertrophy in the rat model. J. Med. Invest. 65:85-89, February, 2018. PMID- 29593201 TI - Adipose tissue:Critical contributor to the development of prostate cancer. AB - The prostate is surrounded by periprostatic adipose tissue. Although adipose tissue was thought to play limited physiological roles, it has recently been recognized as an active endocrine organ, secreting growth factors and adipokines. Epidemiologically, obesity is associated with prostate cancer progression. A major mechanism to explain the link between obesity and cancer includes the insulin and insulin-like growth factor (IGF)-1 axis, sex steroids, and adipokines. When prostate cancer cells invade periprostatic adipose tissue, adipose tissue contributes to create the tumor microenvironment, mainly via adipokine secretion. Furthermore, direct crosstalk between adipocytes and cancer cells can exist. We showed that fatty acid-binding protein 4 (FABP4) released from adipocytes was taken up into prostate cancer cells and may act as a carrier of an energy source for the invasion. Bone is an adipocyte-rich organ and is the common metastatic site of prostate cancer. In the microenvironment of bone metastases, tumor cells, osteoblasts, osteoclasts, adipocytes, and other stromal cells are interacting with one another and organizing a complex system. Thus, growing evidence implicates adipose tissue as a critical contributor to the development of prostate cancer. A deeper understanding of the mechanisms leads to more effective therapeutic strategies for prostate cancer. J. Med. Invest. 65:9 17, February, 2018. PMID- 29593202 TI - A feasibility study of postoperative adjuvant chemotherapy with fluoropyrimidine S-1 in patients with stage II-IIIA non-small cell lung cancer. AB - BACKGROUND: Adjuvant chemotherapy with uracil tegafur (UFT) improved survival among patients with completely resected stage I lung adenocarcinoma. S-1, an oral dihydropyrimidine dehydrogenase (DPD)-inhibitory 5-fluorouracil, is a more potent DPD inhibitor than UFT;therefore, we hypothesized that postoperative adjuvant chemotherapy with S-1 would be effective for advanced non-small cell lung cancer (NSCLC). We conducted a feasibility study of S-1 as postoperative adjuvant chemotherapy in patients with curatively resected pathological stage bold I back 10 bold I and bold I back 10 bold I back 20 bold I A NSCLC. METHODS: Adjuvant chemotherapy consisted of 9 courses (4-week administration, 2-week withdrawal) of S-1 at 80-120 mg/body per day. Twenty-four patients with completely resected NSCLC were enrolled in this study from November 2007 through December 2010. The primary endpoint was the rate of completion of the scheduled adjuvant chemotherapy. The secondary endpoints were safety, overall survival, and relapse free survival. RESULTS: Five patients were censored because of disease recurrence. The planned 9 courses of S-1 were administered to completion in 8 patients. Twelve patients completed more than 70% of the planned courses. Grade 3 adverse reactions, such as elevated total bilirubin (4.2%) and pneumonitis (4.2%), were observed, but there were no Grade 4 adverse reactions. Patients who completed more than 70% of the 9 courses demonstrated better overall survival than those who completed less than 70%. CONCLUSION: Postoperative administration of S-1 may be possible with few severe adverse events as adjuvant chemotherapy for patients with curatively resected pathological stage bold I back 10 bold I bold I back 10 bold I back 20 bold I A NSCLC.

AB - BACKGROUND: Factors such as exposed bones or tendons can inhibit wound healing and make it a lengthy process unless aggressive debridement or vascularized flap surgery are performed. We have developed a new procedure involving simultaneous application of a skin graft and perifascial areolar tissue (PAT) and negative pressure wound therapy. METHODS: Of 8 patients with wounds, bones, tendons, and thick fascia were exposed in 4, 2, and 2 cases, respectively. These wounds were adequately covered with PAT, and split-thickness skin grafts were applied simultaneously on the PAT with a VACsize 4.9 bigcirc size 3.5 back 115 up 4 roman R device. RESULTS: In 6 of 8 cases, the skin graft and PAT were successful, and epithelialization was achieved within 4 weeks. PAT adapted but skin graft was unsuccessful in one case, and both the skin graft and PAT failed to adapt of a pressure ulcer. Using the PAT to overlap more than 400% of the exposed areas resulted in better adaptation. CONCLUSIONS: This procedure contributed to reducing the burden on the patients because we were able to use a skin graft on the exposed areas, without the need for removal of bone or tendons. This potentially means patients avoid loss of function in the affected areas and achieve better outcomes. J. Med. Invest. 65:96-102, February, 2018. PMID- 29593204 TI - Modafinil Dependence: A Case with Attention-Deficit/Hyperactivity Disorder. AB - Modafinil is generally known as a drug with low addiction potential. There are few case reports in the literature demonstrating that Modafinil, stated being capable of diminishing symptoms of attention deficit/hyperactivity disorder (ADHD), causes addiction. In the present article a Modafinil addicted ADHD case, consuming usurious doses (5,000 mg/per day) of Modafinil is presented. The case presented to our psychiatry outpatient clinic due to: requirement of in taking high dose Modafinil in order to achieve the initial effects, difficulty in obtaining the drug, irritability, anxiousness, sleep irregularities, fatigue and unpleasant vivid dreams when he did not use the drug. It was realized that the patient, himself increased doses of Modafinil incrementally, in order to keep its effects on attention symptoms at the same level. It has to be kept in mind that ADHD patients can develop Modafinil addiction. It is necessary to carry out systemic studies on this subject.

AB - A 22-year-old man was admitted with gradually aggravating stereotypic head movement with hypomania. Brain magnetic resonance imaging showed a large suprasellar arachnoid cyst extending into the third ventricle, with obstructive hydrocephalus, characteristic of bobble-head doll syndrome. Endoscopic fenestration of the suprasellar arachnoid cyst was performed. Stereotypic head movement stopped immediately after surgery and hypomanic symptoms gradually improved within a month. During 4 years of follow-up observation without medication, neuropsychiatric symptoms did not relapse. We report our experience of surgically treating stereotypy and hypomania in a case of bobble-head doll syndrome and discuss the possible neuropsychiatric mechanisms of this rare disease.

AB - OBJECTIVE: Little is known about the psychiatric complications or risk factors for depression in suspected or confirmed Middle East Respiratory Syndrome (MERS) patients quarantined in hospital. METHODS: A retrospective chart review was performed of all the patients admitted to the acute MERS inpatient unit at the NMC during the 2015 outbreak. RESULTS: 30 (75%) were confirmed to be MERS-CoV positive among 40 admitted cases. Among the 24 MERS survivors, 17 (70.8%) exhibited psychiatric symptoms and 10 (41.7%) received a psychiatric diagnosis and medication during their hospital stay. Suspected MERS patients did not exhibit psychiatric symptoms or receive a psychiatric diagnosis. 27 suspected or confirmed MERS patients (age 41.15+/-18.64, male 37.0%) completed psychological assessments. A multiple linear regression analysis revealed that the Korean National Health and Nutrition Examination Survey-Short form and the Impact of Event Scale-Revised scores were significantly positively correlated with Patient Health Questionnaire-9 scores. CONCLUSION: Our findings indicate that the acute treatment of MERS-CoV infections in quarantine had a significant impact on the patients' mental health. Furthermore, assessment of the risk factors for depression may identify vulnerable patients who require psychiatric care and attention during hospital quarantine.

AB - Neurologic symptoms that develop unconsciously and are incompatible with known pathophysiologic mechanisms or anatomic pathways belong to Conversion Disorder (CD). CD diagnosis is based on the clinical history and the exclusion of physical disorders causing significant distress or social and occupational impairment. In a subgroup of CD, called functional weakness (FW), symptoms affecting limbs may be persistent, thus causing a permanent or transient loss of limb function. Physiotherapy, pharmacotherapy, hypnotherapy and repetitive transcranial magnetic stimulation (rTMS) have been proposed as treatment strategies for FW-CD. Herein, we report a 30 year-old male, presenting with lower limb functional paraparesis, having obtained positive, objectively, and stable effects from a prolonged r-TMS protocol associated to a multidisciplinary approach, including psychological and sexuological counseling, and monitored by gait analysis. We postulate that our rTMS protocol, combined with a multidisciplinary approach may be the proper treatment strategy to improve FW-CD.

AB - BACKGROUND The aim of this study was to investigate the clinical characteristics of individuals with chronic hepatitis B virus (HBV) infection with persistent low levels of hepatitis B surface antigen (HBsAg) and to undertake a correlation analysis of the clinical characteristics. MATERIAL AND METHODS The study included 1,204 subjects with chronic HBV infection. Serum HBsAg, HBV envelope antigen (HBeAg), and HBV core antigen (HBcAg) levels were measured using the chemiluminescent microparticle immunoassay (CMIA) and the neutralization test. HBV DNA was measured using real-time fluorescence quantitative polymerase chain reaction (RT-FQ-PCR). RESULTS There were 1,023 subjects in the high-level HBsAg group (HBsAg level >=10 IU/mL) and 181 subjects in the low-level HBsAg group (HBsAg level <10 IU/mL). In the low-level HBsAg group, the main serological pattern (93.37%) was HBsAg and HBeAg and HBcAg-positive (HBV-M2), and the asymptomatic carrier (ASC) status was 98.34%. The low-level HBsAg group had a lower HBV DNA-positive rate compared with the high-level HBsAg group (40.33% vs. 75.07%), with a normal distribution across all age groups (P>0.05). The low-level HBsAg group included an older age group. A low-level of HBsAg was positively correlated with a low level of replication of HBV DNA (r=0.452). CONCLUSIONS The findings of this study showed that individuals with chronic HBV infection and sustained low-levels of HBsAg were an older population and had a lower level of replicating HBV DNA when compared with individuals with high levels of HBsAg, and the majority (93.7%) were also HBsAg and HBeAg and HBcAg-positive.

Here we demonstrate proton releases, dioxygen formation, and substrate water incorporation in response to Mn4CaO5 oxidation in the protein environment, using a quantum mechanical/molecular mechanical approach and molecular dynamics simulations. In S2, H2O at the W1 site forms a low-barrier H-bond with D1-Asp61. In the S2-to-S3 transition, oxidation of OW1H- to OW1*-, concerted proton transfer from OW1H- to D1-Asp61, and binding of a water molecule Wn-W1 at OW1*- are observed. In S4, W n-W1 facilitates oxo-oxyl radical coupling between OW1*- and corner MU-oxo O4. Deprotonation via D1-Asp61 leads to formation of OW1=O4. As OW1=O4 moves away from Mn, H2O at W539 is incorporated into the vacant O4 site of the O2-evolved Mn4CaO4 cluster, forming a MU-oxo bridge (Mn3-OW539-Mn4) in an exergonic process. Simultaneously, Wn-W1 is incorporated as W1, recovering the Mn4CaO5 cluster.

AB - The EMT inducer SNAIL1 regulates breast cancer metastasis and its expression in human primary breast tumor predicts for poor outcomes. During tumor progression SNAIL1 has multiple effects in tumor cells that can impact metastasis. An inflammatory tumor microenvironment also impacts metastasis and recently SNAIL1 has been implicated as modulating the secretion of cytokines that can influence the tumor immune infiltrate. Using a spontaneous genetic model of breast cancer metastasis and syngeneic orthotopic transplant experiments we show that the action of SNAIL1 in primary breast tumor cells is required for breast tumor growth and metastasis. It does so, in part, by regulating production of GM-CSF, IL1alpha, IL-6, and TNFalpha by breast cancer cells. The SNAIL1-dependent tumor cell secretome modulates the primary tumor-associated macrophage (TAM) polarization. GM-CSF alone modulates TAM polarization and impacts breast cancer metastasis in vivo. This study highlights another role for breast tumor SNAIL1 in cancer progression to metastasis-modulation of the immune microenvironment of primary breast tumors.

AB - Yellow fever virus (Flavivirus genus) is an arthropod-borne pathogen, which can infect humans, causing a severe viscerotropic disease with a high mortality rate. Adapted viral strains allow the reproduction of yellow fever disease in hamsters with features similar to the human disease. Here, we used the Infectious Subgenomic Amplicons reverse genetics method to produce an equivalent to the hamster-virulent strain, Yellow Fever Ap7, by introducing a set of four synonymous and six nonsynonymous mutations into a single subgenomic amplicon, derived from the sequence of the Asibi strain. The resulting strain, Yellow Fever Ap7M, induced a disease similar to that described for Ap7 in terms of symptoms, weight evolution, viral loads in the liver and lethality. Using the same methodology, we produced mutant strains derived from either Ap7M or Asibi viruses and investigated the role of each of Ap7M nonsynonymous mutations in its in vivo phenotype. This allowed identifying key components of the virulence mechanism in hamsters. In Ap7M virus, the reversion of either E/Q27H or E/D155A mutations led to an important reduction of both virulence and in vivo replicative fitness. In addition, the introduction of the single D155A Ap7M mutation within the E protein of the Asibi virus was sufficient to drastically modify its phenotype in hamsters toward both a greater replication efficiency and virulence. Finally, inspection of the Asibi strain E protein structure combined to in vivo testing revealed the importance of an exposed alpha-helix in domain I, containing residues 154 and 155, for Ap7M virulence in hamsters. PMID- 29593213 TI - Evidence for functional pre-coupled complexes of receptor heteromers and adenylyl cyclase. AB - G protein-coupled receptors (GPCRs), G proteins and adenylyl cyclase (AC) comprise one of the most studied transmembrane cell signaling pathways. However, it is unknown whether the ligand-dependent interactions between these signaling molecules are based on random collisions or the rearrangement of pre-coupled elements in a macromolecular complex. Furthermore, it remains controversial whether a GPCR homodimer coupled to a single heterotrimeric G protein constitutes a common functional unit. Using a peptide-based approach, we here report evidence for the existence of functional pre-coupled complexes of heteromers of adenosine A2A receptor and dopamine D2 receptor homodimers coupled to their cognate Gs and Gi proteins and to subtype 5 AC. We also demonstrate that this macromolecular complex provides the necessary frame for the canonical Gs-Gi interactions at the AC level, sustaining the ability of a Gi-coupled GPCR to counteract AC activation mediated by a Gs-coupled GPCR. PMID- 29593214 TI - Molecular imaging of glycan chains couples cell-wall polysaccharide architecture to bacterial cell morphology. AB - Biopolymer composite cell walls maintain cell shape and resist forces in plants, fungi and bacteria. Peptidoglycan, a crucial antibiotic target and immunomodulator, performs this role in bacteria. The textbook structural model of peptidoglycan is a highly ordered, crystalline material. Here we use atomic force microscopy (AFM) to image individual glycan chains in peptidoglycan from Escherichia coli in unprecedented detail. We quantify and map the extent to which chains are oriented in a similar direction (orientational order), showing it is much less ordered than previously depicted. Combining AFM with size exclusion chromatography, we reveal glycan chains up to 200 nm long. We show that altered cell shape is associated with substantial changes in peptidoglycan biophysical properties. Glycans from E. coli in its normal rod shape are long and circumferentially oriented, but when a spheroid shape is induced (chemically or genetically) glycans become short and disordered. PMID- 29593215 TI - A licensing step links AID to transcription elongation for mutagenesis in B cells. AB - Activation-induced deaminase (AID) mutates the immunoglobulin (Ig) genes to initiate somatic hypermutation (SHM) and class switch recombination (CSR) in B cells, thus underpinning antibody responses. AID mutates a few hundred other loci, but most AID-occupied genes are spared. The mechanisms underlying productive deamination versus non-productive AID targeting are unclear. Here we show that three clustered arginine residues define a functional AID domain required for SHM, CSR, and off-target activity in B cells without affecting AID deaminase activity or Escherichia coli mutagenesis. Both wt AID and mutants with single amino acid replacements in this domain broadly associate with Spt5 and chromatin and occupy the promoter of AID target genes. However, mutant AID fails to occupy the corresponding gene bodies and loses association with transcription elongation factors. Thus AID mutagenic activity is determined not by locus occupancy but by a licensing mechanism, which couples AID to transcription elongation. PMID- 29593216 TI - Klf4 glutamylation is required for cell reprogramming and early embryonic development in mice. AB - Temporal and spatial-specific regulation of pluripotency networks is largely dependent on the precise modifications of core transcription factors. Misregulation of glutamylation is implicated in severe physiological abnormalities. However, how glutamylation regulates cell reprogramming and pluripotency networks remains elusive. Here we show that cytosolic carboxypeptidases 1 (CCP1) or CCP6 deficiency substantially promotes induced pluripotent cell (iPSC) induction and pluripotency of embryonic stem cells (ESCs). Klf4 polyglutamylation at Glu381 by tubulin tyrosine ligase-like 4 (TTLL4) and TTLL1 during cell reprogramming impedes its lysine 48-linked ubiquitination and sustains Klf4 stability. Klf4-E381A knockin mice display impaired blastocyst development and embryonic lethality. Deletion of TTLL4 or TTLL1 abrogates cell reprogramming and early embryogenesis. Thus, Klf4 polyglutamylation plays a critical role in the regulation of cell reprogramming and pluripotency maintenance. PMID- 29593217 TI - Structural characterization of a highly-potent V3-glycan broadly neutralizing antibody bound to natively-glycosylated HIV-1 envelope. AB - Broadly neutralizing antibodies (bNAbs) isolated from HIV-1-infected individuals inform HIV-1 vaccine design efforts. Developing bNAbs with increased efficacy requires understanding how antibodies interact with the native oligomannose and complex-type N-glycan shield that hides most protein epitopes on HIV-1 envelope (Env). Here we present crystal structures, including a 3.8-A X-ray free electron laser dataset, of natively glycosylated Env trimers complexed with BG18, the most potent V3/N332gp120 glycan-targeting bNAb reported to date. Our structures show conserved contacts mediated by common D gene-encoded residues with the N332gp120 glycan and the gp120 GDIR peptide motif, but a distinct Env-binding orientation relative to PGT121/10-1074 bNAbs. BG18's binding orientation provides additional contacts with N392gp120 and N386gp120 glycans near the V3-loop base and engages protein components of the V1-loop. The BG18-natively-glycosylated Env structures facilitate understanding of bNAb-glycan interactions critical for using V3/N332gp120 bNAbs therapeutically and targeting their epitope for immunogen design. PMID- 29593218 TI - Identification and characterization of a novel rodent bocavirus from different rodent species in China. AB - Members in the genus Bocaparvovirus are closely related to human health and have a wide host range. The diverse hosts raise the possibility of crossing species barrier, which is a feature of emerging viruses. Among the mammalian hosts, rodents are generally acknowledged to be important reservoirs of emerging viruses. Here, rodent samples collected from six provinces and autonomous regions of China (Liaoning, Inner Mongolia, Tibet, Xinjiang, Guangxi and Yunnan) were used to investigate the prevalence and distribution of bocaparvoviruses. By using next-generation sequencing first, a partial non-structural protein 1 (NS1) gene belonging to a possible novel bocaparvovirus was discovered. Following this, PCR based screening of NS1 gene was conducted in 485 rodent samples, with 106 positive results found in seven rodent species (Rattus norvegicus, Mus musculus, Apodemus agrarius, Cricetulus barabensis, Rattus flavipectus, Rattus rattus and Rhombomys opimus). Finally, six nearly full-length genomes and three complete CDS were obtained and the newly identified bocaparvovirus was tentatively named rodent bocavirus (RoBoV). RoBoV has three ORFs: NS1, NP1, and VP, which are characteristics of bocaparvoviruses. Phylogenetic analyses revealed that porcine bocavirus isolate PBoV-KU14, a member of Ungulate bocaparvovirus 4, was the most related virus to RoBoV, with 92.1-92.9% amino acid identities in NS1 protein. Alignments of RoBoV-related sequences showed RoBoV isolates could be classified into two clades, demonstrating an inter-host genetic diversity. The results indicate a potential interspecies transmission of RoBoV between rodents and swine and expand our knowledge on bocaparvoviruses in rodent populations. PMID- 29593219 TI - Two-thirds of global cropland area impacted by climate oscillations. AB - The El Nino Southern Oscillation (ENSO) peaked strongly during the boreal winter 2015-2016, leading to food insecurity in many parts of Africa, Asia and Latin America. Besides ENSO, the Indian Ocean Dipole (IOD) and the North Atlantic Oscillation (NAO) are known to impact crop yields worldwide. Here we assess for the first time in a unified framework the relationships between ENSO, IOD and NAO and simulated crop productivity at the sub-country scale. Our findings reveal that during 1961-2010, crop productivity is significantly influenced by at least one large-scale climate oscillation in two-thirds of global cropland area. Besides observing new possible links, especially for NAO in Africa and the Middle East, our analyses confirm several known relationships between crop productivity and these oscillations. Our results improve the understanding of climatological crop productivity drivers, which is essential for enhancing food security in many of the most vulnerable places on the planet. PMID- 29593220 TI - Towards Millimeter-wavelength: Transmission-Mode Fresnel-Zone Plate Lens Antennas using Plastic Material Porosity Control in Homogeneous Medium. AB - We present two transmission-mode dielectric Fresnel-Zone Plate Lens (FZPL) antennas for use within the V-band spectrum. The proposed FZPs are realized via pure plastic material using two different additive manufacturing processes. The proposed FZP lenses are designed with half (lambda/2) and quarter (lambda/4) phase correction rings at 60-GHz with 30lambda0 diameter, where lambda0 is the free-space wavelength. The permittivity effect for lens sub-zones is controlled by material porosity in cube-shaped structures. The 3D printed zone plate lenses are built using additive manufacturing plastic materials with a thickness of lambda0 and constant relative permittivities equal to 2.76 and 3.6. Different types of antenna with cos n -like radiation patterns as lens illuminators are analyzed on the vertical plane of the flat lenses to have a high efficiency over the considered operating band. Simulations and experimental measurements show a reasonably close match, therefore allowing for a reliable predictability. PMID- 29593221 TI - Non-invasive detection of severe neutropenia in chemotherapy patients by optical imaging of nailfold microcirculation. AB - White-blood-cell (WBC) assessment is employed for innumerable clinical procedures as one indicator of immune status. Currently, WBC determinations are obtained by clinical laboratory analysis of whole blood samples. Both the extraction of blood and its analysis limit the accessibility and frequency of the measurement. In this study, we demonstrate the feasibility of a non-invasive device to perform point-of-care WBC analysis without the need for blood draws, focusing on a chemotherapy setting where patients' neutrophils-the most common type of WBC become very low. In particular, we built a portable optical prototype, and used it to collect 22 microcirculatory-video datasets from 11 chemotherapy patients. Based on these videos, we identified moving optical absorption gaps in the flow of red cells, using them as proxies to WBC movement through nailfold capillaries. We then showed that counting these gaps allows discriminating cases of severe neutropenia (<500 neutrophils per uL), associated with increased risks of life threatening infections, from non-neutropenic cases (>1,500 neutrophils per uL). This result suggests that the integration of optical imaging, consumer electronics, and data analysis can make non-invasive screening for severe neutropenia accessible to patients. More generally, this work provides a first step towards a long-term objective of non-invasive WBC counting. PMID- 29593222 TI - CD4+ and CD8+ T Cells Exert Regulatory Properties During Experimental Acute Aristolochic Acid Nephropathy. AB - Experimental aristolochic acid nephropathy is characterized by transient acute proximal tubule necrosis and inflammatory cell infiltrates followed by interstitial fibrosis and tubular atrophy. The respective role of T-cell subpopulations has never been studied in the acute phase of the mouse model, and was heretofore exclusively investigated by the use of several depletion protocols. As compared to mice injected with aristolochic acids alone, more severe acute kidney injury was observed after CD4+ or CD8+ T-cells depletion. TNF alpha and MCP-1 mRNA renal expressions were also increased. In contrast, regulatory T-cells depletion did not modify the severity of the aristolochic acids induced acute kidney injury, suggesting an independent mechanism. Aristolochic acids nephropathy was also associated with an increased proportion of myeloid CD11bhighF4/80mid and a decreased proportion of their counterpart CD11blowF4/80high population. After CD4+ T-cell depletion the increase in the CD11bhighF4/80mid population was even higher whereas the decrease in the CD11blowF4/80high population was more marked after CD8+ T cells depletion. Our results suggest that CD4+ and CD8+ T-cells provide protection against AA-induced acute tubular necrosis. Interestingly, T-cell depletion was associated with an imbalance of the CD11bhighF4/80mid and CD11blowF4/80high populations. PMID- 29593223 TI - Latitudinal trends in human primary activities: characterizing the winter day as a synchronizer. AB - This work analyzes time use surveys from 19 countries (17 European and 2 American) in the middle latitude (38-61 degree) accounting for 45% of world population in this range. Time marks for primary activities are contrasted against light/dark conditions. The analysis reveals winter sunrise synchronizes labor start time below 54 degree, occurring within winter civil twilight. Winter sunset is a source of synchronization for labor end times. Winter terminator punctuate meal times in Europe: dinner occurs 3 h after winter sunset time within 1 h; 40% narrower than variability of dinner local times. The sleep-wake cycle of laborers is shown to be related to winter sunrise whereas standard population's appears to be irrespective of latitude. The significance of the winter terminator depends on two competing factors average labor time (~7 h30 m) and the shortest photoperiod. Winter terminator gains significance when both roughly matches. That is within a latitude range from 38 degree to 54 degree. The significance of winter terminator as a source of synchronization is also related to contemporary year round time schedules: the shortest photoperiod represents the worst case scenario the society faces.

AB - Tropical Rainfall Measuring Mission (TRMM) 3B43 rainfall products during the period of 1998~2016 are evaluated via monthly and yearly precipitation data from 56 observational stations over the Yangtze River Delta (YRD). The results are as follows: (1) annual rainfall increases gradually from northwest to southwest and monthly precipitation surges sharply, owing to rainband's abrupt pushing north caused by the westward and northward extension of Western Pacific Subtropical High, to 200 mm/month in July; (2) only seized by the TRMM, the developing process of ChunAn precipitation center synchronizes with monthly precipitation series that may recycle throughout the year; (3) 3B43 data are inclined to overestimate precipitation but performs the best (relative bias ranging within 10~10%) at most parts of the YRD zone; and its correlation coefficient with observation is 0.88 in annual scale; for monthly scale, CC peaks in March (0.96) and reaches the bottom (0.79) in August; (4) no evident connection between CC and elevation is found in the 3B43 annual rainfall products which estimate precipitation better upon urban land. This paper is of importance in understanding the impacts of complex topography and landcovers on the precipitation assessment in a river delta scale. PMID- 29593225 TI - Large-scale sequence analysis reveals novel human-adaptive markers in PB2 segment of seasonal influenza A viruses. AB - To elucidate the adaptive strategies of influenza A viruses (IAVs) to human, we proposed a computational approach to identify human-adaptive mutations in seasonal IAVs, which have not been analyzed comprehensively. We compared representative PB2 sequences of 1425 avian IAVs and 2176 human IAVs and identified a total of 42 human-adaptive markers, including 28 and 31 markers in PB2 proteins of seasonal viruses H1N1 and H3N2, respectively. Notably, this comprehensive list encompasses almost all the markers identified in prior computational studies and 21 novel markers including an experimentally verified mutation K526R, suggesting the predictive power of our method. The strength of our analysis derives from the enormous amount of recently available sequences as well as the recognition that human-adaptive mutations are not necessarily conserved across subtypes. We also utilized mutual information to profile the inter-residue coevolution in PB2 protein. A total of 35 and 46 coevolving site pairs are identified in H1N1 and H3N2, respectively. Interestingly, 13 out of the 28 (46.4%) identified markers in H1N1 and 16 out of the 31 (51.6%) in H3N2 are embraced in the coevolving pairs. Many of them are paired with well-characterized human-adaptive mutations, indicating potential epistatic effect of these coevolving residues in human adaptation. Additionally, we reconstructed the PB2 evolutionary history of seasonal IAVs and demonstrated the distinct adaptive pathway of PB2 segment after reassortment from H1 to H3 lineage. Our study may provide clues for further experimental validation of human-adaptive mutations and shed light on the human adaptation process of seasonal IAVs. PMID- 29593226 TI - Caffeine Augments Anesthesia Neurotoxicity in the Fetal Macaque Brain. AB - Caffeine is the most frequently used medication in premature infants. It is the respiratory stimulant of choice for apnea associated with prematurity and has been called the silver bullet in neonatology because of many proven benefits and few known risks. Research has revealed that sedative/anesthetic drugs trigger apoptotic death of neurons and oligodendrocytes in developing mammalian brains. Here we evaluated the influence of caffeine on the neurotoxicity of anesthesia in developing nonhuman primate brains. Fetal macaques (n = 7-8/group), at a neurodevelopmental age comparable to premature human infants, were exposed in utero for 5 hours to no drug (control), isoflurane, or isoflurane + caffeine and examined for evidence of apoptosis. Isoflurane exposure increased apoptosis 3.3 fold for neurons and 3.4 fold for oligodendrocytes compared to control brains. Isoflurane + caffeine caused neuronal apoptosis to increase 8.0 fold compared to control levels but did not augment oligoapoptosis. Neuronal death was particularly pronounced in the basal ganglia and cerebellum. Higher blood levels of caffeine within the range considered therapeutic and safe for human infants correlated with increased neuroapoptosis. Caffeine markedly augments neurotoxicity of isoflurane in the fetal macaque brain and challenges the assumption that caffeine is safe for premature infants. PMID- 29593227 TI - The Cish SH2 domain is essential for PLC-gamma1 regulation in TCR stimulated CD8+ T cells. AB - Cish, participates within a multi-molecular E3 ubiquitin ligase complex, which ubiquitinates target proteins. It has an inhibitory effect on T cell activation mediated by PLC-gamma1 regulation, and it functions as a potent checkpoint in CD8+ T cell tumor immunotherapy. To study the structural and functional relationships between Cish and PLC-gamma1 during CD8+ T cell activation, we tested mutants of the Cish-SH2 (R107K) and D/BC (L222Q, C226Q) domains. We confirmed that Cish-SH2-specific binding was essential for PLC-gamma1 ubiquitination and degradation. This domain was essential for the Cish-mediated inhibition of Ca2+ release upon TCR stimulation. No effect on inhibition of cytokine release was observed with SH2 or D/BC mutants, although the absence of Cish led to an increased release of IFN-gamma and TNF-alpha. Using imaging we showed that Cish was expressed mostly in the cytoplasm and we did not see any Cish clustering at the plasma membrane upon stimulation. We conclude that the Cish-SH2 domain is essential for PLC-gamma1 regulation in TCR-stimulated CD8+ T cells. PMID- 29593228 TI - Chronic kidney disease induces a systemic microangiopathy, tissue hypoxia and dysfunctional angiogenesis. AB - Chronic kidney disease (CKD) is associated with excessive mortality from cardiovascular disease (CVD). Endothelial dysfunction, an early manifestation of CVD, is consistently observed in CKD patients and might be linked to structural defects of the microcirculation including microvascular rarefaction. However, patterns of microvascular rarefaction in CKD and their relation to functional deficits in perfusion and oxygen delivery are currently unknown. In this in-vivo microscopy study of the cremaster muscle microcirculation in BALB/c mice with moderate to severe uremia, we show in two experimental models (adenine feeding or subtotal nephrectomy), that serum urea levels associate incrementally with a distinct microangiopathy. Structural changes were characterized by a heterogeneous pattern of focal microvascular rarefaction with loss of coherent microvascular networks resulting in large avascular areas. Corresponding microvascular dysfunction was evident by significantly diminished blood flow velocity, vascular tone, and oxygen uptake. Microvascular rarefaction in the cremaster muscle paralleled rarefaction in the myocardium, which was accompanied by a decrease in transcription levels not only of the transcriptional regulator HIF-1alpha, but also of its target genes Angpt-2, TIE-1 and TIE-2, Flkt-1 and MMP 9, indicating an impaired hypoxia-driven angiogenesis. Thus, experimental uremia in mice associates with systemic microvascular disease with rarefaction, tissue hypoxia and dysfunctional angiogenesis. PMID- 29593229 TI - Effects of smoking habit change on all-cause mortality and cardiovascular diseases among patients with newly diagnosed diabetes in Korea. AB - This study aimed to investigate the effects of smoking habit change on the risks of all-cause mortality and cardiovascular diseases (CVDs) among patients with newly diagnosed diabetes using the Korean National Sample Cohort data. Survival regression analyses for the risks of all-cause mortality and CVDs were performed. Quitters without body mass index (BMI) change (adjusted hazard ratio [aHR], 0.68; 95% confidence interval [CI], 0.46-1.00) and quitters with BMI loss (aHR, 1.76; 95% CI, 1.13-2.73) showed significantly reduced and substantially the increased risk of all-cause mortality, respectively, compared with sustained smokers. Smoking reduction after diabetes diagnosis may have potential positive effects. However, definite benefits on the health outcomes were not identified in this study. Participants who started smoking after diabetes diagnosis had higher risks of all-cause mortality and CVDs than those who were never smokers or ex-smokers, although not statistically significant. In conclusion, smoking cessation after diabetes diagnosis could reduce the risks of all-cause mortality and cardiovascular events among patients with newly diagnosed diabetes when accompanied by proper weight management. Therefore, physicians should advice patients with newly diagnosed type 2 diabetes on the importance of smoking cessation in combination with long-term weight management to maximize the benefits of smoking cessation. PMID- 29593230 TI - Renormalized vibrations and normal energy transport in 1d FPU-like discrete nonlinear Schrodinger equations. AB - For one-dimensional (1d) nonlinear atomic lattices, the models with on-site nonlinearities such as the Frenkel-Kontorova (FK) and phi4 lattices have normal energy transport while the models with inter-site nonlinearities such as the Fermi-Pasta-Ulam-beta (FPU-beta) lattice exhibit anomalous energy transport. The 1d Discrete Nonlinear Schrodinger (DNLS) equations with on-site nonlinearities has been previously studied and normal energy transport has also been found. Here, we investigate the energy transport of 1d FPU-like DNLS equations with inter-site nonlinearities. Extended from the FPU-beta lattice, the renormalized vibration theory is developed for the FPU-like DNLS models and the predicted renormalized vibrations are verified by direct numerical simulations same as the FPU-beta lattice. However, the energy diffusion processes are explored and normal energy transport is observed for the 1d FPU-like DNLS models, which is different from their atomic lattice counterpart of FPU-beta lattice. The reason might be that, unlike nonlinear atomic lattices where models with on-site nonlinearities have one less conserved quantities than the models with inter-site nonlinearities, the DNLS models with on-site or inter-site nonlinearities have the same number of conserved quantities as the result of gauge transformation. PMID- 29593231 TI - Metabolomic approach for a rapid identification of natural products with cytotoxic activity against human colorectal cancer cells. AB - The discovery of bioactive compounds from natural sources entails an extremely lengthy process due to the timescale and complexity of traditional methodologies. In our study, we used a rapid NMR based metabolomic approach as tool to identify secondary metabolites with anti-proliferative activity against a panel of human colorectal cancer cell lines with different mutation profiles. For this purpose, fourteen Fabaceae species of Mediterranean vegetation were investigated using a double screening method: 1H NMR profiling enabled the identification of the main compounds present in the mixtures, whilst parallel biological assays allowed the selection of two plant extracts based on their strong anti-proliferative properties. Using high-resolution 2D NMR spectroscopy, putative active constituents were identified in the mixture and isolated by performing a bio guided fractionation of the selected plant extracts. As a result, we found two active principles: a cycloartane glycoside and protodioscin derivative. Interestingly, these metabolites displayed a preferential anti-proliferative effect on colon cancer cell lines with an intrinsic resistance to anti-EGFR therapies. Our work provides an NMR-based metabolomic approach as a powerful and efficient tool to discover natural products with anticancer activities circumventing time-consuming procedures. PMID- 29593232 TI - Cross-talk between primary osteocytes and bone marrow macrophages for osteoclastogenesis upon collagen treatment. AB - Homeostasis of osteoclast formation from bone marrow macrophages (BMM) is regulated by paracrine signals of the neighbourhood bone cells particularly mesenchymal stem cells (MSC), osteoblasts and osteocytes (OC). Besides paracrine cues, collagen and glycosaminoglycan are involved in controlling bone homeostasis. Towards this approach, different molecular weight collagens were reacted with MSC, OC and BMM to understand the bone homeostasis activity of collagen. The up-regulating effect of collagens on osteogenic cell growth was confirmed by the presence of mineralized nodules in the osteoblastogenic lineage cells and increased osteogenic stimulatory gene expression. The decreased BMM derived TRAP+ osteoclasts number and osteoclastogenic regulatory gene expression of OC could demonstrate the exploitive osteoclastogenic activity of collagens. Osteoclastogenesis from BMM was triggered by paracrine cues of OC in some extend, but it was down-regulated by collagen. Overall, the effect of collagen on osteoclastogenesis and osteoblastogenesis may depend on the molecular weight of collagens, and collagen suppresses osteoclastogenesis, at least in part by downregulating the secretion of cytokines in OC.

AB - The eukaryotic porin, also called the Voltage Dependent Anion-selective Channel (VDAC), is the main pore-forming protein of the outer mitochondrial membrane. In Drosophila melanogaster, a cluster of genes evolutionarily linked to VDAC is present on chromosome 2L. The main VDAC isoform, called VDAC1 (Porin1), is expressed from the first gene of the cluster. The porin1 gene produces two splice variants, 1A-VDAC and 1B-VDAC, with the same coding sequence but different 5' untranslated regions (UTRs). Here, we studied the influence of the two 5' UTRs, 1A-5' UTR and 1B-5' UTR, on transcription and translation of VDAC1 mRNAs. In porin-less yeast cells, transformation with a construct carrying 1A-VDAC results in the expression of the corresponding protein and in complementation of a defective cell phenotype, whereas the 1B-VDAC sequence actively represses VDAC expression. Identical results were obtained using constructs containing the two 5' UTRs upstream of the GFP reporter. A short region of 15 nucleotides in the 1B 5' UTR should be able to pair with an exposed helix of 18S ribosomal RNA (rRNA), and this interaction could be involved in the translational repression. Our data suggest that contacts between the 5' UTR and 18S rRNA sequences could modulate the translation of Drosophila 1B-VDAC mRNA. The evolutionary significance of this finding is discussed.

AB - Co-existence of Parkinson's disease (PD) and essential tremor (ET) may reflect overlapping pathophysiology underlying both conditions. Furthermore, PD patients with leucine-rich repeat kinase-2 (LRRK2) mutations may present with ET-like features, suggesting the possibility of common genetic underpinnings. Two common LRRK2 variants, R1398H and N551K, have been shown to be protective in multiple PD cohorts. We hypothesized that R1398H and N551K may show a similar effect in ET. In a case-control study involving 3198 subjects (2680 controls and 518 ET cases), R1398H was detected in 16.6% of ET cases compared to 18.0% in controls (OR = 0.91, 95% CI = 0.71-1.17, p = 0.46); while N551K was detected in 16.5% of ET cases compared to 18.0% of controls (OR = 0.89, 95% CI = 0.69-1.15, p = 0.37). While these results suggest that LRRK2 R1398H or N551K do not appear to modulate the risk of ET, it remains possible that a protective trend for both variants may be present in ET and a much larger sample size is required to identify this.

AB - Dual-comb spectroscopy has become a powerful spectroscopic technique in applications that rely on its broad spectral coverage combined with high frequency resolution capabilities. Experiments to date have primarily focused on detection and analysis of multiple gas species under semi-static conditions, with applications ranging from environmental monitoring of greenhouse gases to high resolution molecular spectroscopy. Here, we utilize dual-comb spectroscopy to demonstrate broadband, high-resolution, and time-resolved measurements in a laser induced plasma. As a demonstration, we simultaneously detect trace amounts of Rb and K in solid samples with a single laser ablation shot, with transitions separated by over 6 THz (13 nm) and spectral resolution sufficient to resolve isotopic and ground state hyperfine splittings of the Rb D2 line. This new spectroscopic approach offers the broad spectral coverage found in the powerful techniques of laser-induced breakdown spectroscopy (LIBS) while providing the high-resolution and accuracy of cw laser-based spectroscopies. PMID- 29593236 TI - Illusory occlusion affects stereoscopic depth perception. AB - When occlusion and binocular disparity cues conflict, what visual features determine how they combine? Sensory cues, such as T-junctions, have been suggested to be necessary for occlusion to influence stereoscopic depth perception. Here we show that illusory occlusion, with no retinal sensory cues, interacts with binocular disparity when perceiving depth. We generated illusory occlusion using stimuli filled in across the retinal blind spot. Observers viewed two bars forming a cross with the intersection positioned within the blind spot. One of the bars was presented binocularly with a disparity signal; the other was presented monocularly, extending through the blind spot, with no defined disparity. When the monocular bar was perceived as filled in through the blind spot, it was perceived as occluding the binocular bar, generating illusory occlusion. We found that this illusory occlusion influenced perceived stereoscopic depth: depth estimates were biased to be closer or farther, depending on whether a bar was perceived as in front of or behind the other bar, respectively. Therefore, the perceived relative depth position, based on filling in cues, set boundaries for interpreting metric stereoscopic depth cues. This suggests that filling-in can produce opaque surface representations that can trump other depth cues such as disparity. PMID- 29593237 TI - Long-range dependence in earthquake-moment release and implications for earthquake occurrence probability. AB - Since the beginning of the 1980s, when Mandelbrot observed that earthquakes occur on 'fractal' self-similar sets, many studies have investigated the dynamical mechanisms that lead to self-similarities in the earthquake process. Interpreting seismicity as a self-similar process is undoubtedly convenient to bypass the physical complexities related to the actual process. Self-similar processes are indeed invariant under suitable scaling of space and time. In this study, we show that long-range dependence is an inherent feature of the seismic process, and is universal. Examination of series of cumulative seismic moment both in Italy and worldwide through Hurst's rescaled range analysis shows that seismicity is a memory process with a Hurst exponent H ~ 0.87. We observe that H is substantially space- and time-invariant, except in cases of catalog incompleteness. This has implications for earthquake forecasting. Hence, we have developed a probability model for earthquake occurrence that allows for long-range dependence in the seismic process. Unlike the Poisson model, dependent events are allowed. This model can be easily transferred to other disciplines that deal with self-similar processes. PMID- 29593238 TI - Three Hcp homologs with divergent extended loop regions exhibit different functions in avian pathogenic Escherichia coli. AB - Type VI secretion systems (T6SSs) contribute to the pathogenicity of avian pathogenic Escherichia coli (APEC), one of the leading causative agents of sepsis and meningitis in poultry. The Hcp protein is a core component of the T6SS tail tube and acts as an exported receptor and a chaperone of effectors. In this study, four distinct Hcp types (Ia, Ib, IIa, and IIb) were designated in Gram negative bacteria, three of which were widely distributed in APEC. We detected divergence in transcription levels among three hcp clusters in 50% duck serum and demonstrated that hcp1 was upregulated by relieving Fur repression. Further analyses revealed that the host serum could activate the hcp2B operon by H-NS derepression to transcribe the downstream xmtU/xmtV pair for inter-bacterial antagonism. Notably, in a structural analysis based on the genetic classification, Hcp proteins exhibited significant differences in the extended loop regions, suggesting that these regions were related to their functional properties. Indeed, the variant region Vs2 (Loop L2, 3) in Hcp1 and Hcp2B was essential for the delivery of antibacterial effectors and the inhibition of macrophage phagocytosis. Further analyses using a duck model indicated that these Hcps play different roles in the pathogenic processes of APEC and immunoprotection. These results indicated that the functional differentiation of Hcp homologs was driven by differences in transcriptional regulation, extended loop regions, and effector delivery. PMID- 29593239 TI - Attenuated Notch signaling in schizophrenia and bipolar disorder. AB - The Notch signaling pathway plays a crucial role in neurodevelopment and in adult brain homeostasis. We aimed to further investigate Notch pathway activity in bipolar disorder (BD) and schizophrenia (SCZ) by conducting a pathway analysis. We measured plasma levels of Notch ligands (DLL1 and DLK1) using enzyme immunoassays in a large sample of patients (SCZ n = 551, BD n = 246) and healthy controls (HC n = 639). We also determined Notch pathway related gene expression levels by microarray analyses from whole blood in a subsample (SCZ n = 338, BD n = 241 and HC n = 263). We found significantly elevated Notch ligand levels in plasma in both SCZ and BD compared to HC. Significant gene expression findings included increased levels of RFNG and KAT2B (p < 0.001), and decreased levels of PSEN1 and CREBBP in both patient groups (p < 0.001). RBPJ was significantly lower in SCZ vs HC (p < 0.001), and patients using lithium had higher levels of RBPJ (p < 0.001). We provide evidence of altered Notch signaling in both SCZ and BD compared to HC, and suggest that Notch signaling pathway may be disturbed in these disorders. Lithium may ameliorate aberrant Notch signaling. We propose that drugs targeting Notch pathway could be relevant in the treatment of psychotic disorders. PMID- 29593240 TI - Preparation of Zr(Mo,W)2O8 with a larger negative thermal expansion by controlling the thermal decomposition of Zr(Mo,W)2(OH,Cl)2?2H2O. AB - Solid solutions of Zr(Mo,W)2O7(OH,Cl)2?2H2O with a preset ratio of components were prepared by a hydrothermal method. The chemical composition of the solutions was determined by energy dispersive X-ray spectroscopy (EDX). For all the samples of ZrMoxW2-xO7(OH,Cl)2?2H2O (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0), TGA and in situ powder X-ray diffraction (PXRD) studies (300-1100 K) were conducted. For each case, the boundaries of the transformations were determined: Zr(Mo,W)2O7(OH,Cl)2?2H2O -> orthorhombic-ZrMoxW2-xO8 (425-525 K), orthorhombic-ZrMoxW2-xO8 -> cubic-ZrMoxW2-xO8 (700-850 K), cubic-ZrMoxW2-xO8 -> trigonal-ZrMoxW2-xO8 (800-1050 K for x > 1) and cubic-ZrMoxW2-xO8 -> oxides (1000 1075 K for x <= 1). The cell parameters of the disordered cubic-ZrMoxW2-xO8 (space group Pa-3) were measured within 300-900 K, and the thermal expansion coefficients were calculated: -3.5?10-6 - -4.5?10-6 K-1. For the ordered ZrMo1.8W0.2O8 (space group P213), a negative thermal expansion (NTE) coefficient 9.6?10-6 K-1 (300-400 K) was calculated. Orthorhombic-ZrW2O8 is formed upon the decomposition of ZrW2O7(OH,Cl)2?2H2O within 500-800 K. PMID- 29593241 TI - Identification and DNA annotation of a plasmid isolated from Chromobacterium violaceum. AB - Chromobacterium violaceum is a beta-proteobacterium found widely worldwide with important biotechnological properties and is associated to lethal sepsis in immune-depressed individuals. In this work, we report the discover, complete sequence and annotation of a plasmid detected in C. violaceum that has been unnoticed until now. We used DNA single-molecule analysis to confirm that the episome found was a circular molecule and then proceeded with NGS sequencing. After DNA annotation, we found that this extra-chromosomal DNA is probably a defective bacteriophage of approximately 44 kilobases, with 39 ORFs comprising, mostly hypothetical proteins. We also found DNA sequences that ensure proper plasmid replication and partitioning as well as a toxin addiction system. This report sheds light on the biology of this important species, helping us to understand the mechanisms by which C. violaceum endures to several harsh conditions. This discovery could also be a first step in the development of a DNA manipulation tool in this bacterium. PMID- 29593242 TI - The role of CSF1R-dependent macrophages in control of the intestinal stem-cell niche. AB - Colony-stimulating factor 1 (CSF1) controls the growth and differentiation of macrophages.CSF1R signaling has been implicated in the maintenance of the intestinal stem cell niche and differentiation of Paneth cells, but evidence of expression of CSF1R within the crypt is equivocal. Here we show that CSF1R dependent macrophages influence intestinal epithelial differentiation and homeostasis. In the intestinal lamina propria CSF1R mRNA expression is restricted to macrophages which are intimately associated with the crypt epithelium, and is undetectable in Paneth cells. Macrophage ablation following CSF1R blockade affects Paneth cell differentiation and leads to a reduction of Lgr5+ intestinal stem cells. The disturbances to the crypt caused by macrophage depletion adversely affect the subsequent differentiation of intestinal epithelial cell lineages. Goblet cell density is enhanced, whereas the development of M cells in Peyer's patches is impeded. We suggest that modification of the phenotype or abundance of macrophages in the gut wall alters the development of the intestinal epithelium and the ability to sample gut antigens.

PMID- 29593245 TI - Evaluation and optimization of differentiation conditions for human primary brown adipocytes. AB - As an effective way to improve energy expenditure, increasing the mass and activity of brown adipose tissue (BAT) has become a promising treatment for obesity and its associated disorders. Many efforts have been made to promote brown adipogenesis and increase the thermogenic capacity of brown adipose cells (BACs). The present culture schemes for human BAC differentiation are mostly derived from white adipocyte differentiation schemes. To solve this issue, we compared the adipogenic and thermogenic effects of various components on human BAC differentiation and optimized their concentrations as well as the culture time for BAC differentiation. In this study, we found that the induction factors did not show a dose-dependent promotion of brown adipogenesis or thermogenic capacity. The higher differentiation levels did not inevitably result in higher BAT-specific gene expression levels or increased beta3-receptor agonist sensitivity. As an important element of culture medium, triiodothyronine was found to be essential for differentiation and metabolic property maintenance. Furthermore, compared with other reported methods, this protocol induced a specific intrinsic differentiation program. Our study provides not only an optimized method for human BAC differentiation but also a cell model with good differentiation and thermogenic capacity for brown adipose research. PMID- 29593246 TI - Emerging recombinant noroviruses identified by clinical and waste water screening. AB - Norovirus is estimated to cause 677 million annual cases of gastroenteritis worldwide, resulting in 210,000 deaths. As viral gastroenteritis is generally self-limiting, clinical samples for epidemiological studies only partially represent circulating noroviruses in the population and is biased towards severe symptomatic cases. As infected individuals from both symptomatic and asymptomatic cases shed viruses into the sewerage system at a high concentration, waste water samples are useful for the molecular epidemiological analysis of norovirus genotypes at a population level. Using Illumina MiSeq and Sanger sequencing, we surveyed circulating norovirus within Australia and New Zealand, from July 2014 to December 2016. Importantly, norovirus genomic diversity during 2016 was compared between clinical and waste water samples to identify potential pandemic variants, novel recombinant viruses and the timing of their emergence. Although the GII.4 Sydney 2012 variant was prominent in 2014 and 2015, its prevalence significantly decreased in both clinical and waste water samples over 2016. This was concomitant with the emergence of multiple norovirus strains, including twoGII.4 Sydney 2012 recombinant viruses, GII.P4 New Orleans 2009/GII.4 Sydney 2012 and GII.P16/GII.4 Sydney 2012, along with three other emerging strains GII.17, GII.P12/GII.3 and GII.P16/GII.2. This is unusual, as a single GII.4 pandemic variant is generally responsible for 65-80% of all human norovirus infections at any one time and predominates until it is replaced by a new pandemic variant. In sumary, this study demonstrates the combined use of clinical and wastewater samples provides a more complete picture of norovirus circulating within the population. PMID- 29593247 TI - A new cell-laden 3D Alginate-Matrigel hydrogel resembles human breast cancer cell malignant morphology, spread and invasion capability observed "in vivo". AB - Purpose of this study was the development of a 3D material to be used as substrate for breast cancer cell culture. We developed composite gels constituted by different concentrations of Alginate (A) and Matrigel (M) to obtain a structurally stable-in-time and biologically active substrate. Human aggressive breast cancer cells (i.e. MDA-MB-231) were cultured within the gels. Known the link between cell morphology and malignancy, cells were morphologically characterized and their invasiveness correlated through an innovative bioreactor based invasion assay. A particular type of gel (i.e. 50% Alginate, 50% Matrigel) emerged thanks to a series of significant results: 1. cells exhibited peculiar cytoskeleton shapes and nuclear fragmentation characteristic of their malignancy; 2. cells expressed the formation of the so-called invadopodia, actin-based protrusion of the plasma membrane through which cells anchor to the extracellular matrix; 3. cells were able to migrate through the gels and attach to an engineered membrane mimicking the vascular walls hosted within bioreactor, providing a completely new 3D in vitro model of the very precursor steps of metastasis. PMID- 29593249 TI - Inside out: regenerative medicine for recessive dystrophic epidermolysis bullosa. AB - Epidermolysis bullosa is classified as a genodermatosis, an inherited genetic skin disorder that results in severe, chronic skin blistering with painful and life-threatening complications. Although there is currently no cure for epidermolysis bullosa, concurrent advances in gene and stem cell therapies are converging toward combinatorial therapies that hold the promise of clinically meaningful and lifelong improvement. Recent studies using hematopoietic stem cells and mesenchymal stromal/stem cells to treat epidermolysis bullosa have demonstrated the potential for sustained, effective management of the most severe cases. Furthermore, advances in the use of gene therapy and gene-editing techniques, coupled with the development of induced pluripotent stem cells from patients with epidermolysis bullosa, allow for autologous therapies derived from a renewable population of cells that are patient-specific. Here we describe emerging treatments for epidermolysis bullosa and other genodermatoses, along with a discussion of their benefits and limitations as effective therapies. PMID- 29593250 TI - Size-dependent activity and selectivity of carbon dioxide photocatalytic reduction over platinum nanoparticles. AB - Platinum nanoparticles (Pt NPs) are one of the most efficient cocatalysts in photocatalysis, and their size determines the activity and the selectivity of the catalytic reaction. Nevertheless, an in-depth understanding of the platinum's size effect in the carbon dioxide photocatalytic reduction is still lacking. Through analyses of the geometric features and electronic properties with variable-sized Pt NPs, here we show a prominent size effect of Pt NPs in both the activity and selectivity of carbon dioxide photocatalytic reduction. Decreasing the size of Pt NPs promotes the charge transfer efficiency, and thus enhances both the carbon dioxide photocatalytic reduction and hydrogen evolution reaction (HER) activity, but leads to higher selectivity towards hydrogen over methane. Combining experimental results and theoretical calculations, in Pt NPs, the terrace sites are revealed as the active sites for methane generation; meanwhile, the low-coordinated sites are more favorable in the competing HER. PMID- 29593251 TI - Targeting MDMX and PKCdelta to improve current uveal melanoma therapeutic strategies. AB - Uveal melanoma (UM) is the most frequent ocular cancer in adults, accounting for ~5% of the total melanoma incidence. Although the primary tumor is well treatable, patients frequently develop metastases for which no curative therapy exists. Highly activated protein kinase C (PKC) is a common feature of UM and has shown potential as therapeutic intervention for UM patients. Unfortunately, PKC inhibition as single treatment appears to have only limited clinical benefit. Combining PKC inhibition with activation of p53, which is rarely mutated in UM, by MDM2 inhibitors has shown promising results in vitro and in vivo. However, clinical studies have shown strong adverse effects of MDM2 inhibition. Therefore, we investigated alternative approaches to achieve similar anticancer effects, but with potentially less adverse effects. We studied the potential of targeting MDMX, an essential p53 inhibitor during embryonal development but less universally expressed in adult tissues compared with MDM2. Therefore, targeting MDMX is predicted to have less adverse effects in patients. Depletion of MDMX, like the pharmacological activation of p53, inhibits the survival of UM cells, which is enhanced in combination with PKC inhibition. Also pan-PKC inhibitors elicit adverse effects in patients. As the PKC family consists of 10 different isoforms, it could be hypothesized that targeting a single PKC isoform would have less adverse effects compared with a pan-PKC inhibitor. Here we show that specifically depleting PKCdelta inhibits UM cell growth, which can be further enhanced by p53 reactivation. In conclusion, our data show that the synergistic effects of p53 activation by MDM2 inhibition and broad spectrum PKC inhibition on survival of UM cells can also largely be achieved by the presumably less toxic combination of depletion of MDMX and targeting a specific PKC isoform, PKCdelta. PMID- 29593253 TI - Development, characterization and dissolution behavior of calcium-aluminoborate glass wasteforms to immobilize rare-earth oxides. AB - Calcium-aluminoborate (CAB) glasses were developed to sequester new waste compositions made of several rare-earth oxides generated from the pyrochemical reprocessing of spent nuclear fuel. Several important wasteform properties such as waste loading, processability and chemical durability were evaluated. The maximum waste loading of the CAB compositions was determined to be ~56.8 wt%. Viscosity and the electrical conductivity of the CAB melt at 1300 degrees C were 7.817 Pa.s and 0.4603 S/cm, respectively, which satisfies the conditions for commercial cold-crucible induction melting (CCIM) process. Addition of rare-earth oxides to CAB glasses resulted in dramatic decreases in the elemental releases of B and Ca in aqueous dissolution experiments. Normalized elemental releases from product consistency standard chemical durability test were <3.62.10-5 g.m-2 for Nd, 0.009 g.m-2 for Al, 0.067 g.m-2 for B and 0.073 g.m-2 for Ca (at 90, after 7 days, for SA/V = 2000m-1); all meet European and US regulation limits. After 20 d of dissolution, a hydrated alteration layer of ~ 200-nm-thick, Ca-depleted and Nd rich, was formed at the surface of CAB glasses with 20 mol% Nd2O3 whereas boehmite [AlO(OH)] secondary crystalline phases were formed in pure CAB glass that contained no Nd2O3. PMID- 29593252 TI - Dedicated photoreceptor pathways in Drosophila larvae mediate navigation by processing either spatial or temporal cues. AB - To integrate changing environmental cues with high spatial and temporal resolution is critical for animals to orient themselves. Drosophila larvae show an effective motor program to navigate away from light sources. How the larval visual circuit processes light stimuli to control navigational decision remains unknown. The larval visual system is composed of two sensory input channels, Rhodopsin5 (Rh5) and Rhodopsin6 (Rh6) expressing photoreceptors (PRs). We here characterize how spatial and temporal information are used to control navigation. Rh6-PRs are required to perceive temporal changes of light intensity during head casts, while Rh5-PRs are required to control behaviors that allow navigation in response to spatial cues. We characterize how distinct behaviors are modulated and identify parallel acting and converging features of the visual circuit. Functional features of the larval visual circuit highlight the principle of how early in a sensory circuit distinct behaviors may be computed by partly overlapping sensory pathways. PMID- 29593254 TI - Phylogenetic analysis and virulence determinant of the host-adapted Staphylococcus aureus lineage ST188 in China. AB - Staphylococcus aureus (S. aureus) is an important pathogen of humans and livestock species, but an understanding of the clonal distribution of S. aureus causing different host-species infections in the same geographical environment and within the same period is lacking. By characterizing infections caused by S. aureus in bovine, pediatric, and adult patients in Shanghai, China, between 2012 and 2014, we identified methicillin-sensitive S. aureus (MSSA) ST188 as the major lineage causing infections in multiple host species. Whole-genome sequencing and phenotypic analyses demonstrated that ST188 might evolve from livestock, and there was no significant genomic or virulence difference between ST188 isolated from livestock and humans. The virulence of ST188 is related to its adhesion and nasal colonization ability. This result is in accord with the strong epithelial cell adhesion and biofilm formation properties of ST188. Furthermore, the adhesion- and biofilm-formation-related genes are present in multiple copies and exhibit significantly increased expression in ST188. In conclusion, S. aureus ST188 is the major lineage causing human and livestock infections in Shanghai, China. Due to its high expression of the factors associated with bacterial adhesion and biofilm formation, ST188 has the ability to colonize and infect different host species. PMID- 29593255 TI - Stress-induced phosphoprotein 1 acts as a scaffold protein for glycogen synthase kinase-3 beta-mediated phosphorylation of lysine-specific demethylase 1. AB - Stress-induced phosphoprotein 1 (STIP1)-a co-chaperone of heat shock proteins promotes cell proliferation and may act as an oncogenic factor. Similarly, glycogen synthase kinase-3 beta (GSK3beta)-mediated phosphorylation of lysine specific demethylase 1 (LSD1)-an epigenetic regulator-can contribute to the development of an aggressive cell phenotype. Owing to their ability to tether different molecules into functional complexes, scaffold proteins have a key role in the regulation of different signaling pathways in tumorigenesis. Here, we show that STIP1 acts as a scaffold promoting the interaction between LSD1 and GSK3beta. Specifically, the TPR1 and TPR2B domains of STIP1 are capable of binding with the AOL domain of LSD1, whereas the TPR2A and TPR2B domains of STIP1 interact with the kinase domain of GSK3beta. We also demonstrate that STIP1 is required for GSK3beta-mediated LSD1 phosphorylation, which promoted LSD1 stability and enhanced cell proliferation. After transfection of cancer cells with double-mutant (S707A/S711A) LSD1, subcellular localization analysis revealed that LSD1 was translocated from the nucleus to the cytoplasm. In vitro experiments also showed that the LSD1 inhibitor SP2509 and the GSK3beta inhibitor LY2090314 acted synergistically to induce cancer cell death. Finally, the immunohistochemical expression of STIP1 and LSD1 showed a positively correlation in human cancer specimens. In summary, our data provide mechanistic insights into the role of STIP1 in human tumorigenesis by showing that it serves as a scaffold for GSK3beta-mediated LSD1 phosphorylation. The combination of LSD1 and GSK3beta inhibitors may exert synergistic antitumor effects and deserves further scrutiny in preclinical studies. PMID- 29593256 TI - Microencephaly in fetal piglets following in utero inoculation of Zika virus. AB - Zika virus (ZIKV) is a mosquito-borne flavivirus that became associated with microcephaly in newborns and Guillain-Barre syndrome in adults after its emergence in the Pacific and the Americas in 2015. Newly developed rodent and nonhuman primate models have already revealed important insights into ZIKV induced neuropathology. Nonhuman primates are phylogenetically closely related to humans and are therefore preferred human surrogates in ZIKV research. However, the use of nonhuman primates, particularly during gestation, raises ethical issues. Considering that pigs also share many anatomical and physiological features with humans, this species may be an attractive alternative human surrogate for ZIKV research. Here, we inoculated 20 porcine fetuses in utero and assessed the effect of ZIKV on brain development 4 weeks later. All inoculated fetuses presented mild to severe neuropathology, characterized by a depletion of neurons in the cerebral cortex. In most cases, neuronal depletion was confined to specific cerebral lobes without affecting brain size, whereas in severe cases a more generalized depletion resulted in microencephaly. Although the virus was widespread in the sows' placenta at the time of necropsy only low levels of viral RNA were detected in fetal brain samples, thereby preventing the identification of primary target cells. Our findings suggest that pigs can be used to study ZIKV induced neurodevelopmental defects as currently observed in human neonates, varying from stunted brain growth to localized cortical neuronal depletion in the absence of major macroscopic abnormalities. PMID- 29593257 TI - Lung Topology Characteristics in patients with Chronic Obstructive Pulmonary Disease. AB - Quantitative features that can currently be obtained from medical imaging do not provide a complete picture of Chronic Obstructive Pulmonary Disease (COPD). In this paper, we introduce a novel analytical tool based on persistent homology that extracts quantitative features from chest CT scans to describe the geometric structure of the airways inside the lungs. We show that these new radiomic features stratify COPD patients in agreement with the GOLD guidelines for COPD and can distinguish between inspiratory and expiratory scans. These CT measurements are very different to those currently in use and we demonstrate that they convey significant medical information. The results of this study are a proof of concept that topological methods can enhance the standard methodology to create a finer classification of COPD and increase the possibilities of more personalized treatment. PMID- 29593258 TI - Oxygen radical character in group 11 oxygen fluorides. AB - Transition metal complexes bearing terminal oxido ligands are quite common, yet group 11 terminal oxo complexes remain elusive. Here we show that excited coinage metal atoms M (M = Au, Ag, Cu) react with OF2 to form hypofluorites FOMF and group 11 oxygen metal fluorides OMF2, OAuF and OAgF. These compounds have been characterized by IR matrix-isolation spectroscopy in conjunction with state-of the-art quantum-chemical calculations. The oxygen fluorides are formed by photolysis of the initially prepared hypofluorites. The linear molecules OAgF and OAuF have a 3Sigma - ground state with a biradical character. Two unpaired electrons are located mainly at the oxygen ligand in antibonding O-M pi* orbitals. For the 2B2 ground state of the OMIIIF2 compounds only an O-M single bond arises and a significant spin-density contribution was found at the oxygen atom as well.

AB - While the circulation of avian influenza viruses (IAV) in wild birds in the northern hemisphere has been well documented, data from South America remain sparse. To address this gap in knowledge, we undertook IAV surveillance in wild birds in parts of Central and Northern Chile between 2012 and 2015. A wide diversity of hemagglutinin (HA) and neuraminidase (NA) subtypes were identified and 16 viruses were isolated including low pathogenic H5 and H7 strains, making this the largest and most diverse collection of Chilean avian IAVs to date. Unlike IAVs isolated from wild birds in other South American countries where the genes were most like viruses isolated from wild birds in either North America or South America, the Chilean viruses were reassortants containing genes like viruses isolated from both continents. In summary, our studies demonstrate that genetically diverse avian IAVs are circulating in wild birds in Chile highlighting the need for further investigation in this understudied area of the world.

AB - The pentazolate anion, as a polynitrogen species, holds great promise as a high energy density material for explosive or propulsion applications. Designing pentazole complexes that contain minimal non-energetic components is desirable in order to increase the material's energy density. Here, we report a solvent-free pentazolate complex, AgN5, and a 3D energetic-framework, [Ag(NH3)2]+[Ag3(N5)4]-, constructed from silver and cyclo-N5-. The complexes are stable up to 90 degrees C and only Ag and N2 are observed as the final decomposition products. Efforts to isolate pure AgN5 were unsuccessful due to partial photolytical and/or thermal decomposition to AgN3. Convincing evidence for the formation of AgN5 as the original reaction product is presented. The isolation of a cyclo-N5- complex, devoid of stabilizing molecules and ions, such as H2O, H3O+, and NH4+, constitutes a major advance in pentazole chemistry.

AB - A wide range of mammals are susceptible to infection by the fungal species Coccidioides immitis and C. posadasii. In humans, 60% of infections are asymptomatic; however, certain patients may develop a severe and deep systemic mycosis called coccidioidomycosis. Genetic analysis suggests that the majority of clinical isolates recovered from South America are C. posadasii; however, little is known about the prevalence, species distribution, and ecological factors that favor the occurrence of this pathogen in those areas. By using a combined quantitative polymerase chain reaction (qPCR)-based approach and mycobiome amplicon sequencing, we provide evidence that at least two genotypes of C. posadasii are found in the xerophytic environment in Venezuela. We detected a 3806-fold range in the amount of Coccidioides DNA when comparing among the sampled locations, which indicates that human exposure risk is variable, and is one critical factor for disease manifestation. We identified fungal communities that are correlated with a higher prevalence of C. posadasii, suggesting that a combination of specific microbes and a xeric microenvironment may favor the growth of Coccidioides in certain locations. Moreover, we discuss the use of a combinatorial approach, using both qPCR and deep-sequencing methods to assess and monitor fungal pathogen burden at outbreak sources. PMID- 29593264 TI - Downregulation of cytoplasmic DNases is implicated in cytoplasmic DNA accumulation and SASP in senescent cells. AB - Accumulating evidence indicates that the senescence-associated secretory phenotype (SASP) contributes to many aspects of physiology and disease. Thus, controlling the SASP will have tremendous impacts on our health. However, our understanding of SASP regulation is far from complete. Here, we show that cytoplasmic accumulation of nuclear DNA plays key roles in the onset of SASP. Although both DNase2 and TREX1 rapidly remove the cytoplasmic DNA fragments emanating from the nucleus in pre-senescent cells, the expression of these DNases is downregulated in senescent cells, resulting in the cytoplasmic accumulation of nuclear DNA. This causes the aberrant activation of cGAS-STING cytoplasmic DNA sensors, provoking SASP through induction of interferon-beta. Notably, the blockage of this pathway prevents SASP in senescent hepatic stellate cells, accompanied by a decline of obesity-associated hepatocellular carcinoma development in mice. These findings provide valuable new insights into the roles and mechanisms of SASP and possibilities for their control. PMID- 29593265 TI - Lymphotoxin alpha fine-tunes T cell clonal deletion by regulating thymic entry of antigen-presenting cells. AB - Medullary thymic epithelial cells (mTEC) purge the T cell repertoire of autoreactive thymocytes. Although dendritic cells (DC) reinforce this process by transporting innocuous peripheral self-antigens, the mechanisms that control their thymic entry remain unclear. Here we show that mTEC-CD4+ thymocyte crosstalk regulates the thymus homing of SHPS-1+ conventional DCs (cDC), plasmacytoid DCs (pDC) and macrophages. This homing process is controlled by lymphotoxin alpha (LTalpha), which negatively regulates CCL2, CCL8 and CCL12 chemokines in mTECs. Consequently, Ltalpha-deficient mice have increased expression of these chemokines that correlates with augmented classical NF-kappaB subunits and increased thymic recruitment of cDCs, pDCs and macrophages. This enhanced migration depends mainly on the chemokine receptor CCR2, and increases thymic clonal deletion. Altogether, this study identifies a fine-tuning mechanism of T cell repertoire selection and paves the way for therapeutic interventions to treat autoimmune disorders. PMID- 29593266 TI - Compositional heterogeneity near the base of the mantle transition zone beneath Hawaii. AB - Global seismic discontinuities near 410 and 660 km depth in Earth's mantle are expressions of solid-state phase transitions. These transitions modulate thermal and material fluxes across the mantle and variations in their depth are often attributed to temperature anomalies. Here we use novel seismic array analysis of SS waves reflecting off the 410 and 660 below the Hawaiian hotspot. We find amplitude-distance trends in reflectivity that imply lateral variations in wavespeed and density contrasts across 660 for which thermodynamic modeling precludes a thermal origin. No such variations are found along the 410. The inferred 660 contrasts can be explained by mantle composition varying from average (pyrolitic) mantle beneath Hawaii to a mixture with more melt-depleted harzburgite southeast of the hotspot. Such compositional segregation was predicted, from petrological and numerical convection studies, to occur near hot deep mantle upwellings like the one often invoked to cause volcanic activity on Hawaii. PMID- 29593267 TI - Gold Nanorods as Visual Sensing Platform for Chiral Recognition with Naked Eyes. AB - Chirality plays a key role in modern science and technology. Here, we report a simple and effective sensing platform for visual chiral recognition of enantiomers. In this sensing platform, gold nanorods (AuNRs) prepared through a common synthesis route are used as colorimetric probes for visual recognition of glutamine (Gln) enantiomers. D-Gln could rapidly induce the aggregation of AuNRs, thereby resulting in appreciable blue-to-gray color change of AuNRs solution; however, L-Gln could not induce color change of AuNRs. This distinct color change can be easily distinguished by the naked eyes; as a result, a visual method of chiral recognition was suggested. The method was applied to determine the enantiometric excess of D-Gln through the whole range of -100% ~ 100%. The chiral assay can be performed with a simple UV-vis spectrometer or the naked eyes. Notably, the AuNRs do not need any chiral labeling or modification, and the chiral recognition is based on the inherent chirality of AuNRs. This chiral assay method is simple, sensitive, cheap and easy to operate. This study is the first example using AuNRs for direct visual recognition of enantiomers, and will open new opportunity to construct more chiral recognition methods for some important compounds. PMID- 29593269 TI - Laser speckle flowgraphy derived characteristics of optic nerve head perfusion in normal tension glaucoma and healthy individuals: a Pilot study. AB - The purpose of this prospective, case control study was to investigate the differences in optic nerve head blood flow measured with Laser Speckle Flowgraphy (LSFG) between Caucasian patients with normal tension glaucoma and healthy subjects. It included 20 eyes from 20 Caucasian patients with diagnosis of normal tension glaucoma and 20 eyes from age- and sex-matched healthy individuals. In the glaucoma group the antiglaucomatous therapy was paused 3 weeks prior to the investigations. Measurement of optic nerve head blood flow was performed with LSFG. The mean blur rate was obtained for different vascular compartments of the optic nerve head. Parameters for the characterization of pulse-waveform of the mean blur rate were calculated. It was shown that the mean blur rate was significantly lower in the glaucoma group compared to the control group (P < 0.001). The significant differences in the pulse-waveform parameters blow out time (P = 0.028) and flow acceleration time index (P < 0.001) indicate a flatter curve in NTG patients. In conclusion, LSFG can detect differences in optic nerve head blood flow between eyes with normal tension glaucoma and healthy eyes. PMID- 29593268 TI - A complex epistatic network limits the mutational reversibility in the influenza hemagglutinin receptor-binding site. AB - The hemagglutinin (HA) receptor-binding site (RBS) in human influenza A viruses is critical for attachment to host cells, which imposes a functional constraint on its natural evolution. On the other hand, being part of the major antigenic sites, the HA RBS of human H3N2 viruses needs to constantly mutate to evade the immune system. From large-scale mutagenesis experiments, we here show that several of the natural RBS substitutions become integrated into an extensive epistatic network that prevents substitution reversion. X-ray structural analysis reveals the mechanistic consequences as well as changes in the mode of receptor binding. Further studies are necessary to elucidate whether such entrenchment limits future options for immune escape or adversely affect long-term viral fitness. PMID- 29593270 TI - Sample-Index Misassignment Impacts Tumour Exome Sequencing. AB - Sample pooling enabled by dedicated indexes is a common strategy for cost effective and robust high-throughput sequencing. Index misassignment leading to mutual contamination between pooled samples has however been described as a general problem of the latest Illumina sequencing instruments utilizing exclusion amplification. Using real-life data from multiple tumour sequencing projects, we demonstrate that index misassignment can induce artefactual variant calls closely resembling true, high-quality somatic variants. These artefactual calls potentially impact cancer applications utilizing low allelic frequencies, such as in clonal analysis of tumours. We discuss the available countermeasures with an emphasis on improved library indexing methods, and provide software that can assist in the identification of variants that may be consequences of index misassignment. PMID- 29593271 TI - Evaluating the efficacy of a landscape scale feral cat control program using camera traps and occupancy models. AB - The impact of introduced predators is a major factor limiting survivorship and recruitment of many native Australian species. In particular, the feral cat and red fox have been implicated in range reductions and population declines of many conservation dependent species across Australia, including ground-nesting birds and small to medium-sized mammals. The impact of predation by feral cats since their introduction some 200 years ago has altered the structure of native fauna communities and led to the development of landscape-scale threat abatement via baiting programs with the feral cat bait, Eradicat. Demonstrating the effectiveness of broad-scale programs is essential for managers to fine tune delivery and timing of baiting. Efficacy of feral cat baiting at the Fortescue Marsh in the Pilbara, Western Australia was tested using camera traps and occupancy models. There was a significant decrease in probability of site occupancy in baited sites in each of the five years of this study, demonstrating both the effectiveness of aerial baiting for landscape-scale removal of feral cats, and the validity of camera trap monitoring techniques for detecting changes in feral cat occupancy during a five-year baiting program. PMID- 29593272 TI - Aftershock sequences and seismic-like organization of acoustic events produced by a single propagating crack. AB - Brittle fractures of inhomogeneous materials like rocks, concrete, or ceramics are of two types: Nominally brittle and driven by the propagation of a single dominant crack or quasi-brittle and resulting from the accumulation of many microcracks. The latter goes along with acoustic noise, whose analysis has revealed that events form aftershock sequences obeying characteristic laws reminiscent of those in seismology. Yet, their origin lacks explanation. Here we show that such a statistical organization is not only specific to the multi cracking situations of quasi-brittle failure and seismology, but also rules the acoustic events produced by a propagating crack. This simpler situation has permitted us to relate these laws to the overall scale-free distribution of inter event time and energy and to uncover their selection by the crack speed. These results provide a comprehensive picture of how acoustic events are organized upon material failure in the most fundamental of fracture states: single propagating cracks. PMID- 29593273 TI - Nuclear disarmament verification via resonant phenomena. AB - Nuclear disarmament treaties are not sufficient in and of themselves to neutralize the existential threat of the nuclear weapons. Technologies are necessary for verifying the authenticity of the nuclear warheads undergoing dismantlement before counting them toward a treaty partner's obligation. Here we present a concept that leverages isotope-specific nuclear resonance phenomena to authenticate a warhead's fissile components by comparing them to a previously authenticated template. All information is encrypted in the physical domain in a manner that amounts to a physical zero-knowledge proof system. Using Monte Carlo simulations, the system is shown to reveal no isotopic or geometric information about the weapon, while readily detecting hoaxing attempts. This nuclear technique can dramatically increase the reach and trustworthiness of future nuclear disarmament treaties. PMID- 29593274 TI - On the nucleus composition during isothermal alloy solidification. AB - Accurate determination of the nucleus composition during isothermal alloy solidification still represents a great challenge nowadays. In this paper, a kinetic scheme was added to the Hillert-Rettenmayr thermodynamic analysis of the deviation from local equilibrium at migrating phase interfaces. A so-called interface permeability was introduced to account for the unambiguous determination of the energy dissipation of the solute rearrangement at the liquid solid interface and the driving force for interface movement, from which the nucleus composition can be then evaluated. After benchmark test, a pragmatic nucleation model for solidification was also proposed, and applied in three dimensional phase-field simulations of nucleation and subsequent dendritic growth during isothermal solidification process in one hypothetic Al-Si alloy. Moreover, the influence of the interface permeability on nucleation rate was fully discussed by exploring its effect on the initial nucleus components and the corresponding nucleation driving force. PMID- 29593275 TI - Genomic epidemiology of the UK outbreak of the emerging human fungal pathogen Candida auris. AB - Candida auris was first described in 2009, and it has since caused nosocomial outbreaks, invasive infections, and fungaemia across at least 19 countries on five continents. An outbreak of C. auris occurred in a specialized cardiothoracic London hospital between April 2015 and November 2016, which to date has been the largest outbreak in the UK, involving a total of 72 patients. To understand the genetic epidemiology of C. auris infection both within this hospital and within a global context, we sequenced the outbreak isolate genomes using Oxford Nanopore Technologies and Illumina platforms to detect antifungal resistance alleles and reannotate the C. auris genome. Phylogenomic analysis placed the UK outbreak in the India/Pakistan clade, demonstrating an Asian origin; the outbreak showed similar genetic diversity to that of the entire clade, and limited local spatiotemporal clustering was observed. One isolate displayed resistance to both echinocandins and 5-flucytosine; the former was associated with a serine to tyrosine amino acid substitution in the gene FKS1, and the latter was associated with a phenylalanine to isoleucine substitution in the gene FUR1. These mutations add to a growing body of research on multiple antifungal drug targets in this organism. Multiple differential episodic selection of antifungal resistant genotypes has occurred within a genetically heterogenous population across this outbreak, creating a resilient pathogen and making it difficult to define local scale patterns of transmission and implement outbreak control measures. PMID- 29593276 TI - Fluorescent label-free quantitative detection of nano-sized bioparticles using a pillar array. AB - Disease diagnostics requires detection and quantification of nano-sized bioparticles including DNA, proteins, viruses, and exosomes. Here, a fluorescent label-free method for sensitive detection of bioparticles is explored using a pillar array with micrometer-sized features in a deterministic lateral displacement (DLD) device. The method relies on measuring changes in size and/or electrostatic charges of 1 um polymer beads due to the capture of target bioparticles on the surface. These changes can be sensitively detected through the lateral displacement of the beads in the DLD array, wherein the lateral shifts in the output translates to a quantitative measurement of bioparticles bound to the bead. The detection of albumin protein and nano-sized polymer vesicles with a concentration as low as 10 ng mL-1 (150 pM) and 3.75 MUg mL-1, respectively, is demonstrated. This label-free method holds potential for point of-care diagnostics, as it is low-cost, fast, sensitive, and only requires a standard laboratory microscope for detection. PMID- 29593277 TI - Prevalence and serogroup changes of Neisseria meningitidis in South Korea, 2010 2016. AB - Determination of the major serogroups is an important step for establishing a vaccine programme and management strategy targeting Neisseria meningitidis. From April 2010 to November 2016, a total of 25 N. meningitidis isolates were collected in South Korea, in collaboration with the Korean Society of Clinical Microbiology. Among isolates, 19 isolates were recovered from blood and/or cerebrospinal fluid (CSF) in 46 patients who suffered from invasive meningococcal disease (IMD), and six isolates were found in sputum or the throat. The most common serogroup was serogroup B (overall, 36%, n = 9/25; IMD, 37%, n = 7/19), which was isolated in every year of the research period except for 2011. There were five serogroup W isolates recovered from patients in military service. W was no longer isolated after initiation of a vaccine programme for military trainees, but serogroup B caused meningitis in an army recruit training centre in 2015. In MLST analysis, 14 sequence types were found, and all isolates belonging to W showed the same molecular epidemiologic characteristics (W:P1.5-1, 2-2:F3-9:ST 8912). All isolates showed susceptibility to ceftriaxone, meropenem, ciprofloxacin, minocycline, and rifampin; however, the susceptibility rates to penicillin and ampicillin for isolates with W and C capsules were 22% and 30%, respectively. PMID- 29593278 TI - Determining the effect of different environmental conditions on Ebola virus viability in clinically relevant specimens. AB - In 2013-2016, West Africa experienced the largest and longest Ebola virus disease outbreak ever documented. The wide geographic spread and magnitude of the outbreak often limited the timely and rapid testing of diagnostic samples from patients with suspected Ebola virus disease, raising questions regarding the optimal storage and shipping conditions of clinically relevant specimens, including EDTA-whole blood, plasma, capillary blood, urine and seminal fluid (associated with sexual transmission of the Ebola virus after recovery from the disease). Therefore, the aim of our study was to identify the extent to which storage temperature and clinical specimen type influence Ebola virus viability. Virus infectivity was determined using a fluorescent focus-forming assay. In our study, we show that Ebola virus was the most stable in EDTA-whole blood and plasma samples, whereas rapid decay of infectivity was observed in simulated capillary blood, urine and semen samples, especially when these samples were stored at higher temperatures. The analysis of variance results demonstrated that both temperature and clinical specimen type have significant effects on virus viability, whereas donor differences were not observed. Repeated freeze and thaw cycles of the samples also had a notable impact on virus viability in EDTA-whole blood and urine. Due to the rapid temperature- and specimen-dependent degradation of the virus observed here, our study highlights the importance of proper clinical sample storage at low temperatures during transportation and laboratory analysis. PMID- 29593279 TI - Asymmetric electric field screening in van der Waals heterostructures. AB - A long-standing challenge facing the combination of two-dimensional crystals into heterojunction is the unknown effect of mixing layer of different electronic properties (semiconductors, metals, insulators) on the screening features of the fabricated device platforms including their functionality. Here we use a compelling set of theoretical and experimental techniques to elucidate the intrinsic dielectric screening properties of heterostructures formed by MoS2 and graphene layers. We experimentally observed an asymmetric field screening effect relative to the polarization of the applied gate bias into the surface. Surprisingly, such behavior allows selection of the electronic states that screen external fields, and it can be enhanced with increasing of the number of layers of the semiconducting MoS2 rather than the semi-metal. This work not only provides unique insights on the screening properties of a vast amount of heterojunction fabricated so far, but also uncovers the great potential of controlling a fundamental property for device applications. PMID- 29593280 TI - Multi-nanolayered VO2/Sapphire Thin Film via Spinodal Decomposition. AB - Coating of VO2-based thin film has been extensively studied for fabricating energy-saving smart windows. One of the most efficient ways for fabricating high performance films is to create multi-nanolayered structure. However, it has been highly challenge to make such layers in the VO2-based films using conventional methods. In this work, a facile two-step approach is established to fabricate multilayered VO2-TiO2 thin films. We first deposited the amorphous thin films upon sputtering, and then anneal them to transform the amorphous phase into alternating Ti- and V-rich multilayered nanostructure via a spinodal decomposition mechanism. In particular, we take advantage of different sapphire substrate planes (A-plane (11-20), R-plane (1-102), C-plane (0001), and M-plane (10-10)) to achieve different decomposition modes. The new approach has made it possible to tailoring the microstructure of the thin films for optimized performances by controlling the disorder-order transition in terms of both kinetic and thermodynamic aspects. The derived thin films exhibit superior optical modulation upon phase transition, significantly reduced transition temperature and hysteresis loop width, and high degradation resistance, these improvements indicate a high potential to be used for fabricating the next generation of energy saving smart windows. PMID- 29593281 TI - Long-term effects of low calcium dialysates on the serum calcium levels during maintenance hemodialysis treatments: A systematic review and meta-analysis. AB - Hypercalcemia and hyperparathyroidism in patients receiving maintenance hemodialysis (MHD) can cause the progression of cardiovascular diseases (CVD) and mineral bone disorders (MBD). The KDIGO recommends the dialysates with a calcium (Ca) concentration of 1.25-1.5 mmol/L for MHD treatments, but the optimal concentration remains controversial. Here, we conducted a systematic review and a meta-analysis of seven randomized controlled trials examining a total of 622 patients to investigate the optimal concentration for MHD for 6 months or longer. The dialysates with a low Ca concentration (1.125 or 1.25 mmol/L) significantly lowered the serum Ca and raised the intact parathyroid hormone levels by 0.52 mg/dL (95% confidence interval, 0.20-0.85) and 39.59 pg/mL (14.80-64.38), respectively, compared with a high Ca concentration (1.50 or 1.75 mmol/L). Three studies showed that a low concentration was preferred for lowering arterial calcifications or atherosclerosis in different arteries, but one study showed that coronary arterial calcifications increased with a low concentration. Two studies showed contradictory outcomes in terms of MBD. Our meta-analysis showed that a dialysate with a low Ca concentration lowered the serum Ca levels in patients receiving long-term MHD, but further studies are needed to determine the optimal Ca concentration in terms of CVD and MBD. PMID- 29593282 TI - Vitamin C promotes apoptosis in breast cancer cells by increasing TRAIL expression. AB - Genomic loss of 5-hydroxymethylcytosine (5hmC) accompanies malignant cellular transformation in breast cancer. Vitamin C serves as a cofactor for TET methylcytosine dioxygenases to increase 5hmC generation. Here we show that the transcription of SVCT2, a major vitamin C transporter, was decreased in human breast cancers (113 cases) compared to normal breast tissues from the same patients. A decreased SVCT2 expression was also observed in breast cancer cell lines. Treatment with vitamin C (100 MUM) increased the 5hmC content in MDA-MB 231 breast cancer cells and markedly altered the transcriptome. The vitamin C treatment induced apoptosis in MDA-MB-231 cells, which was verified in two additional breast cancer cell lines. This pro-apoptotic effect of vitamin C appeared to be mediated by TRAIL, a known apoptosis inducer. Vitamin C upregulated TRAIL transcripts (2.3-fold increase) and increased TRAIL protein levels. The upregulation of TRAIL by vitamin C was largely abolished by siRNAs targeting TETs and anti-TRAIL antibody abrogated the induction of apoptosis. Furthermore, the apoptosis promoted by vitamin C was associated with Bax and caspases activation, Bcl-xL sequestration, and cytochrome c release. Taken together, these results suggest a potential role of physiological doses of vitamin C in breast cancer prevention and treatment.

PMID- 29593284 TI - Cementoin-SLPI fusion protein binds to human monocytes and epithelial cells and shows higher biological activity than SLPI. AB - Secretory Leukocyte Proteinase Inhibitor (SLPI) is an antiinflammatory peptide that blocks the activity of serine proteases, primarily the neutrophil elastase. In an attempt to direct the activity of SLPI on inflamed sites, a chimera consisting of the transglutaminase II substrate domain of trappin 2 (cementoin), and the mature SLPI protein was constructed. Cell attachment and biological activity were compared between SLPI and this chimera. By using whole cell ELISA, fluorescence microscopy and flow cytometry assays we observed that the cementoin SLPI fusion protein (FP) but not SLPI attached to a human lung epithelial cell line and monocytes. A maximum attachment was achieved 15 min after FP was added to the cell cultures. In an elastase activity assay, we observed that FP retained its antiprotease activity and that at equimolar amount of proteins, FP was more efficient than SLPI in the inhibition. Both, FP and SLPI inhibits IL-2-induced lymphocyte proliferation, however, lower amounts of FP were required to achieve this inhibition. Furthermore, FP binds to mycobacteria and maintained the bactericidal activity observed for SLPI. Overall, these results show that this new chimera is able to attach to the cell surfaces retaining and improving some biological activities described for SLPI. PMID- 29593283 TI - Breast and pancreatic cancer interrupt IRF8-dependent dendritic cell development to overcome immune surveillance. AB - Tumors employ multiple mechanisms to evade immune surveillance. One mechanism is tumor-induced myelopoiesis, whereby the expansion of immunosuppressive myeloid cells can impair tumor immunity. As myeloid cells and conventional dendritic cells (cDCs) are derived from the same progenitors, we postulated that myelopoiesis might impact cDC development. The cDC subset, cDC1, which includes human CD141+ DCs and mouse CD103+ DCs, supports anti-tumor immunity by stimulating CD8+ T-cell responses. Here, to understand how cDC1 development changes during tumor progression, we investigated cDC bone marrow progenitors. We found localized breast and pancreatic cancers induce systemic decreases in cDC1s and their progenitors. Mechanistically, tumor-produced granulocyte-stimulating factor downregulates interferon regulatory factor-8 in cDC progenitors, and thus results in reduced cDC1 development. Tumor-induced reductions in cDC1 development impair anti-tumor CD8+ T-cell responses and correlate with poor patient outcomes. These data suggest immune surveillance can be impaired by tumor-induced alterations in cDC development. PMID- 29593286 TI - Hypertension: Hypertension intervention at the barbershop.

Their ubiquity and relevance have stimulated the development of efficient mathematical models able to predict biofilm evolution and characteristics at different conditions. Here we present a study of the early stages of bacterial biofilm formation modeled by means of individual cell-based computer simulation. Simulation showed that clusters with different degrees of internal and orientational order were formed as a function of the aspect ratio of the individual particles and the relation between the diffusion and growth rates. Analysis of microscope images of early biofilm formation by the Gram-negative bacterium Pseudomonas putida at varying diffusion rates revealed a good qualitative agreement with the simulation results. Our model is a good predictor of microcolony morphology during early biofilm development, showing that the competition between diffusion and growth rates is a key aspect in the formation of stable biofilm microcolonies. PMID- 29593290 TI - Methane stimulates massive nitrogen loss from freshwater reservoirs in India. AB - The fate of the enormous amount of reactive nitrogen released to the environment by human activities in India is unknown. Here we show occurrence of seasonal stratification and generally low concentrations of dissolved inorganic combined nitrogen, and high molecular nitrogen (N2) to argon ratio, thus suggesting seasonal loss to N2 in anoxic hypolimnia of several dam-reservoirs. However, 15N experiments yielded low rates of denitrification, anaerobic ammonium oxidation and dissimilatory nitrate reduction to ammonium-except in the presence of methane (CH4) that caused ~12-fold increase in denitrification. While nitrite-dependent anaerobic methanotrophs belonging to the NC10 phylum were present, previously considered aerobic methanotrophs were far more abundant (up to 13.9%) in anoxic hypolimnion. Methane accumulation in anoxic freshwater systems seems to facilitate rapid loss of reactive nitrogen, with generally low production of nitrous oxide (N2O), through widespread coupling between methanotrophy and denitrification, potentially mitigating eutrophication and emissions of CH4 and N2O to the atmosphere. PMID- 29593291 TI - Structural insights into the RNA methyltransferase domain of METTL16. AB - N6-methyladenosine (m6A) is an abundant modification in messenger RNA and noncoding RNAs that affects RNA metabolism. Methyltransferase-like protein 16 (METTL16) is a recently confirmed m6A RNA methyltransferase that methylates U6 spliceosomal RNA and interacts with the 3'-terminal RNA triple helix of MALAT1 (metastasis-associated lung adenocarcinoma transcript 1). Here, we present two X ray crystal structures of the N-terminal methyltransferase domain (residues 1 291) of human METTL16 (METTL16_291): an apo structure at 1.9 A resolution and a post-catalytic S-adenosylhomocysteine-bound complex at 2.1 A resolution. The structures revealed a highly conserved Rossmann fold that is characteristic of Class I S-adenosylmethionine-dependent methyltransferases and a large, positively charged groove. This groove likely represents the RNA-binding site and it includes structural elements unique to METTL16. In-depth analysis of the active site led to a model of the methyl transfer reaction catalyzed by METTL16. In contrast to the major m6A methyltransferase heterodimer METTL3/METTL14, full length METTL16 forms a homodimer and METTL16_291 exists as a monomer based on size-exclusion chromatography. A native gel-shift assay shows that METTL16 binds to the MALAT1 RNA triple helix, but monomeric METTL16_291 does not. Our results provide insights into the molecular structure of METTL16, which is distinct from METTL3/METTL14. PMID- 29593292 TI - A globally-distributed alien invasive species poses risks to United States imperiled species. AB - In the midst of Earth's sixth mass extinction event, non-native species are a driving factor in many imperiled species' declines. One of the most widespread and destructive alien invasive species in the world, wild pigs (Sus scrofa) threaten native species through predation, habitat destruction, competition, and disease transmission. We show that wild pigs co-occur with up to 87.2% of imperiled species in the contiguous U.S. identified as susceptible to their direct impacts, and we project increases in both the number of species at risk and the geographic extent of risks by 2025. Wild pigs may therefore present a severe threat to U.S. imperiled species, with serious implications for management of at-risk species throughout wild pigs' global distribution. We offer guidance for efficient allocation of research effort and conservation resources across species and regions using a simple approach that can be applied to wild pigs and other alien invasive species globally. PMID- 29593294 TI - Characteristics of the fads2 gene promoter in marine teleost Epinephelus coioides and role of Sp1-binding site in determining promoter activity. AB - Delta6 fatty acyl desaturase (Fads2) is a rate-limiting enzyme in long-chain polyunsaturated fatty acids (LC-PUFA) biosynthesis. Comparative analysis of gene promoters of Fads2 between salmonids and carnivorous marine fish suggested that the lack of binding site for stimulatory protein 1 (Sp1) was responsible for the low expression of fads2 gene of carnivorous marine species. To confirm this speculation, the fads2 candidate promoter (2646 bp) was cloned from carnivorous marine teleost Epinephelus coioides, and 330 bp core regulatory region was identified. Several binding sites for transcriptional factors such as nuclear factor 1, nuclear factor Y, sterol regulatory element and hepatocyte nuclear factor 4gamma were identified, while that for Sp1 was shown to be absent in the promoter by both bioinformatic analysis and site-directed mutation. Moreover, after the Sp1-binding site from the fads2 promoter of herbivorous Siganus canaliculatus, the first marine teleost demonstrated to have LC-PUFA biosynthetic ability, was inserted into the corresponding region of E. coioides fads2 promoter, activity was significantly increased. The results provided direct data for the importance of the Sp1-binding site in determining fads2 promoter activity, and indicated that its lack may be a reason for low expression of fads2 and poor LC-PUFA biosynthetic ability in E. coioides.

AB - Autophagy emerges as an essential immunity defense against intracellular pathogens. Here we report that turnip mosaic virus (TuMV) infection activates autophagy in plants and that Beclin1 (ATG6), a core component of autophagy, inhibits virus replication. Beclin1 interacts with NIb, the RNA-dependent RNA polymerase (RdRp) of TuMV, via the highly conserved GDD motif and the interaction complex is targeted for autophagic degradation likely through the adaptor protein ATG8a. Beclin1-mediated NIb degradation is inhibited by autophagy inhibitors. Deficiency of Beclin1 or ATG8a enhances NIb accumulation and promotes viral infection and vice versa. These data suggest that Beclin1 may be a selective autophagy receptor. Overexpression of a Beclin1 truncation mutant that binds to NIb but lacks the ability to mediate NIb degradation also inhibits virus replication. The Beclin1-RdRp interaction further extends to several RNA viruses. Thus Beclin1 restricts viral infection through suppression and also likely autophagic degradation of the viral RdRp. PMID- 29593295 TI - Dexras1 is a homeostatic regulator of exercise-dependent proliferation and cell survival in the hippocampal neurogenic niche. AB - Adult hippocampal neurogenesis is highly responsive to exercise, which promotes the proliferation of neural progenitor cells and the integration of newborn granule neurons in the dentate gyrus. Here we show that genetic ablation of the small GTPase, Dexras1, suppresses exercise-induced proliferation of neural progenitors, alters survival of mitotic and post-mitotic cells in a stage specific manner, and increases the number of mature newborn granule neurons. Dexras1 is required for exercise-triggered recruitment of quiescent neural progenitors into the cell cycle. Pharmacological inhibition of NMDA receptors enhances SGZ cell proliferation in wild-type but not dexras1-deficient mice, suggesting that NMDA receptor-mediated signaling is dependent on Dexras1. At the molecular level, the absence of Dexras1 abolishes exercise-dependent activation of ERK/MAPK and CREB, and inhibits the upregulation of NMDA receptor subunit NR2A, bdnf, trkB and vegf-a expression in the dentate gyrus. Our study reveals Dexras1 as an important stage-specific regulator of exercise-induced neurogenesis in the adult hippocampus by enhancing pro-mitogenic signaling to neural progenitor cells and modulating cell survival. PMID- 29593296 TI - Automated brightfield morphometry of 3D organoid populations by OrganoSeg. AB - Spheroid and organoid cultures are powerful in vitro models for biology, but size and shape diversity within the culture is largely ignored. To streamline morphometric profiling, we developed OrganoSeg, an open-source software that integrates segmentation, filtering, and analysis for archived brightfield images of 3D culture. OrganoSeg is more accurate and flexible than existing platforms, and we illustrate its potential by stratifying 5167 breast-cancer spheroid and 5743 colon and colorectal-cancer organoid morphologies. Organoid transcripts grouped by morphometric signature heterogeneity were enriched for biological processes not prominent in the original RNA sequencing data. OrganoSeg enables complete, objective quantification of brightfield phenotypes, which may give insight into the molecular and multicellular mechanisms of organoid regulation. PMID- 29593297 TI - Over-elongation of centrioles in cancer promotes centriole amplification and chromosome missegregation. AB - Centrosomes are the major microtubule organising centres of animal cells. Deregulation in their number occurs in cancer and was shown to trigger tumorigenesis in mice. However, the incidence, consequence and origins of this abnormality are poorly understood. Here, we screened the NCI-60 panel of human cancer cell lines to systematically analyse centriole number and structure. Our screen shows that centriole amplification is widespread in cancer cell lines and highly prevalent in aggressive breast carcinomas. Moreover, we identify another recurrent feature of cancer cells: centriole size deregulation. Further experiments demonstrate that severe centriole over-elongation can promote amplification through both centriole fragmentation and ectopic procentriole formation. Furthermore, we show that overly long centrioles form over-active centrosomes that nucleate more microtubules, a known cause of invasiveness, and perturb chromosome segregation. Our screen establishes centriole amplification and size deregulation as recurrent features of cancer cells and identifies novel causes and consequences of those abnormalities. PMID- 29593298 TI - Opn5L1 is a retinal receptor that behaves as a reverse and self-regenerating photoreceptor. AB - Most opsins are G protein-coupled receptors that utilize retinal both as a ligand and as a chromophore. Opsins' main established mechanism is light-triggered activation through retinal 11-cis-to-all-trans photoisomerization. Here we report a vertebrate non-visual opsin that functions as a Gi-coupled retinal receptor that is deactivated by light and can thermally self-regenerate. This opsin, Opn5L1, binds exclusively to all-trans-retinal. More interestingly, the light induced deactivation through retinal trans-to-cis isomerization is followed by formation of a covalent adduct between retinal and a nearby cysteine, which breaks the retinal-conjugated double bond system, probably at the C11 position, resulting in thermal re-isomerization to all-trans-retinal. Thus, Opn5L1 acts as a reverse photoreceptor. We conclude that, like vertebrate rhodopsin, Opn5L1 is a unidirectional optical switch optimized from an ancestral bidirectional optical switch, such as invertebrate rhodopsin, to increase the S/N ratio of the signal transduction, although the direction of optimization is opposite to that of vertebrate rhodopsin. PMID- 29593299 TI - Bacterial diversity and community structure in the rhizosphere of four Ferula species. AB - The medicinal value of the Ferula L. has been recognized for more than a thousand years. Wild stocks of Ferula have declined dramatically because high economic value has led to overharvesting. The objective of this study was to compare the rhizosphere microbial community of four Ferula species [F. syreitschikowii K. Pol., F. gracilis (Ledeb.) Ledeb., F. ferulaeoides (Steud.) Korov., and F. lehmannii Boiss.] in the northern part of Xinjiang, China. The 16S rRNA sequences of rhizosphere bacteria were obtained with an Illumina paired-end sequence platform. Analysis was conducted to determine the richness and diversity of the rhizosphere bacterial communities. Two-way ANOVA indicated that plant species and soil depth had no significant effect on the alpha diversity of rhizobacteria. Linear discriminant analysis effect size showed that F. lehmannii followed by F. ferulaeoides had the most biomarkers and the highest taxon level, F. syreitschikowii and F. gracilis the least, while F. syreitschikowii and F. gracilis had the least property. This trend is consistent with reports that the medicinal value of F. lehmannii and F. ferulaeoides is greater than that of F. gracilis and F. syreitschikowii. The results of this study provide information that could be used for the commercial cultivation of Ferula spp. PMID- 29593301 TI - InAs/AlGaAs quantum dots for single-photon emission in a red spectral range. AB - We report on comparative optical studies of InAs/Al0.44Ga0.56As quantum dots (QDs) grown by molecular beam epitaxy either with or without a thin GaAs interlayer inserted between the AlGaAs barrier and InAs QDs. Emission properties of individual QDs are investigated by micro-photoluminescence spectroscopy using 500-nm-size etched cylindric mesa structures. The single-photon statistics of the QDs of both types, emitting in the red spectral range between 636 and 750 nm, is confirmed by the measurements of the second-order correlation function. A negligibly small exciton fine structure splitting is detected in the majority of the QDs grown with the GaAs interlayer that implies the possibility of generating pairs of entangled photons with high entanglement fidelity. PMID- 29593300 TI - Surviving threats: neural circuit and computational implications of a new taxonomy of defensive behaviour. AB - Research on defensive behaviour in mammals has in recent years focused on elicited reactions; however, organisms also make active choices when responding to danger. We propose a hierarchical taxonomy of defensive behaviour on the basis of known psychological processes. Included are three categories of reactions (reflexes, fixed reactions and habits) and three categories of goal-directed actions (direct action-outcome behaviours and actions based on implicit or explicit forecasting of outcomes). We then use this taxonomy to guide a summary of findings regarding the underlying neural circuits. PMID- 29593302 TI - Unexpected Crossover in the kinetics of mutarotation in the supercooled region: the role of H-bonds. AB - Intra- and intermolecular studies on the molten L-sorbose have been carried out at variable temperature conditions to determine the crosover temperature (T c ). In addition, isothermal time-dependent FTIR and Raman measurements were performed to probe the pace of mutarotation and activation energy of this reaction in the studied saccharide, which varied from 53-62 kJ/mol up to 177-192 kJ/mol below and above T c , respectively. To explain the change in activation barrier for the mutarotation a complementary analysis using difference FTIR spectra collected around T c = 365 K in the hydroxyl region has been done. It was found that the alteration of kinetic parameters and molecular dynamics around T c are strictly related to the variation in the strength of H-bonds which above T c are significantly weaken, increasing the freedom of rotation of functional groups and movement of individual molecules. That phenomenon most likely affects the proton transfer, underlying molecular mechanism of mutarotation, which may lead to the significant increase in activation barrier. The new insight into a molecular aspect of the mutarotation around T c has created an opportunity to better understanding the relationship between physics of condensed matter and the potential role of H-bonds dynamics on the progress of the chemical reaction in highly viscous systems. PMID- 29593303 TI - Epigenetic Transgenerational Inheritance of Altered Sperm Histone Retention Sites. AB - A variety of environmental toxicants and factors have been shown to induce the epigenetic transgenerational inheritance of disease and phenotypic variation. Epigenetic alterations in the germline (sperm or egg) are required to transmit transgenerational phenotypes. The current study was designed to investigate the potential role of histones in sperm to help mediate the epigenetic transgenerational inheritance. The agricultural fungicide vinclozolin and the pesticide DDT (dichlorodiphenyltrichloroethane) were independently used to promote the epigenetic transgenerational inheritance of disease. Purified cauda epididymal sperm were collected from the transgenerational F3 generation control and exposure lineage male rats for histone analysis. A reproducible core of histone H3 retention sites was observed using an H3 chromatin immunoprecipitation (ChIP-Seq) analysis in control lineage sperm. Interestingly, the same core group of H3 retention sites plus additional differential histone retention sites (DHRs) were observed in the F3 generation exposure lineage sperm. Although new histone H3 retention sites were observed, negligible change in histone modification (methylation of H3K27me3) was observed between the control and exposure lineages. Observations demonstrate that in addition to alterations in sperm DNA methylation and ncRNA previously identified, the induction of differential histone retention sites (DHRs) also appear to be involved in environmentally induced epigenetic transgenerational inheritance. PMID- 29593304 TI - Quantum probe hyperpolarisation of molecular nuclear spins. AB - Hyperpolarisation of nuclear spins is important in overcoming sensitivity and resolution limitations of magnetic resonance imaging and nuclear magnetic resonance spectroscopy. Current hyperpolarisation techniques require high magnetic fields, low temperatures, or catalysts. Alternatively, the emergence of room temperature spin qubits has opened new pathways to achieve direct nuclear spin hyperpolarisation. Employing a microwave-free cross-relaxation induced polarisation protocol applied to a nitrogen vacancy qubit, we demonstrate quantum probe hyperpolarisation of external molecular nuclear spins to ~50% under ambient conditions, showing a single qubit increasing the polarisation of ~106 nuclear spins by six orders of magnitude over the thermal background. Results are verified against a detailed theoretical treatment, which also describes how the system can be scaled up to a universal quantum hyperpolarisation platform for macroscopic samples. Our results demonstrate the prospects for this approach to nuclear spin hyperpolarisation for molecular imaging and spectroscopy and its potential to extend beyond into other scientific areas. PMID- 29593305 TI - Pigmentation pattern and developmental constraints: flight muscle attachment sites delimit the thoracic trident of Drosophila melanogaster. AB - In their seminal paper published in 1979, Gould and Lewontin argued that some traits arise as by-products of the development of other structures and not for direct utility in themselves. We show here that this applies to the trident, a pigmentation pattern observed on the thorax of Drosophila melanogaster. Using reporter constructs, we show that the expression domain of several genes encoding pigmentation enzymes follows the trident shape. This domain is complementary to the expression pattern of stripe (sr), which encodes an essential transcription factor specifying flight muscle attachment sites. We demonstrate that sr limits the expression of these pigmentation enzyme genes to the trident by repressing them in its own expression domain, i.e. at the flight muscle attachment sites. We give evidence that repression of not only yellow but also other pigmentation genes, notably tan, is involved in the trident shape. The flight muscle attachment sites and sr expression patterns are remarkably conserved in dipterans reflecting the essential role of sr. Our data suggest that the trident is a by product of flight muscle attachment site patterning that arose when sr was co opted for the regulation of pigmentation enzyme coding genes. PMID- 29593306 TI - Effect of live yeast Saccharomyces cerevisiae (Actisaf Sc 47) supplementation on the performance and hindgut microbiota composition of weanling pigs. AB - As an alternative to antibiotic growth promoters, live yeast supplementation has proven useful in reducing weaning stress and improving performance parameters of piglets. Here, we compared the performance and hindgut microbiota of weanling piglets subjected to different pre- and post-weaning yeast supplementation regimens using a live strain of Saccharomyces cerevisiae (Actisaf Sc 47). Average feed intake and average daily weight gain of piglets within Yeast-Control and Yeast-Yeast groups were higher than those in the Control-Control group. Yeast supplementation resulted in development of microbial communities that were phylogenetically more homogenous and less dispersed compared to the microbiota of control piglets. Key bacterial taxa overrepresented in the microbiota of yeast supplemented piglets included phylum Actinobacteria, specifically family Coriobacteriaceae, as well as Firmicutes families Ruminococcaceae, Clostridiaceae, Peptostreptococcaceae, and Peptococcaceae. Correlation network analysis revealed that yeast supplementation was associated with enrichment of positive correlations among proportions of different bacterial genera within the hindgut ecosystem. In particular, within the cecal microbiota of supplemented piglets, higher numbers of positive correlations were observed among potentially beneficial genera of the phyla Actinobacteria and Firmicutes, suggesting a mechanism by which yeast supplementation may contribute to regulation of intestinal homeostasis and improved performance of piglets. PMID- 29593308 TI - The Anti-Cancer Multikinase Inhibitor Sorafenib Impairs Cardiac Contractility by Reducing Phospholamban Phosphorylation and Sarcoplasmic Calcium Transients. AB - Tyrosine-kinase inhibitors (TKIs) have revolutionized cancer therapy in recent years. Although more targeted than conventional chemotherapy, TKIs exhibit substantial cardiotoxicity, often manifesting as hypertension or heart failure. Here, we assessed myocyte intrinsic cardiotoxic effects of the TKI sorafenib and investigated underlying alterations of myocyte calcium homeostasis. We found that sorafenib reversibly decreased developed force in auxotonically contracting human myocardia (3 uM: -25 +/- 4%, 10 uM: -29 +/- 7%, 30 uM: -43 +/- 12%, p < 0.01), reduced peak cytosolic calcium concentrations in isolated cardiomyocytes (10 uM: 52 +/- 8.1% of baseline, p < 0.001), and slowed cytosolic calcium removal kinetics (RT50, RT10, Tau, p < 0.05). Beta-adrenergic stimulation induced augmentation of calcium transient (CaT) amplitude was attenuated in sorafenib treated cells (2.7 +/- 0.3-fold vs. 3.6 +/- 0.2-fold in controls, p < 0.001). Sarcoplasmic reticulum (SR) calcium content was reduced to 67 +/- 4% (p < 0.01), and SR calcium re-uptake slowed (p < 0.05). Sorafenib significantly reduced serine 16 phosphorylation of phospholamban (PLN, p < 0.05), while PLN threonine 17 and CaMKII (T286) phosphorylation were not altered. Our data demonstrate that sorafenib acutely impairs cardiac contractility by reducing S16 PLN phosphorylation, leading to reduced SR calcium content, CaT amplitude, and slowed cytosolic calcium removal. These results indicate myocyte intrinsic cardiotoxicity irrespective of effects on the vasculature and chronic cardiac remodeling. PMID- 29593307 TI - Morphology of Immunomodulation in Breast Cancer Tumor Draining Lymph Nodes Depends on Stage and Intrinsic Subtype. AB - Cancer research of immune-modulating mechanisms mainly addresses the role of tumor-infiltrating immune cells. Mechanisms modulating the adaptive immune system at the primary activation site - the draining lymph node (LN) - are less investigated. Here we present tumor-caused histomorphological changes in tumor draining LNs of breast cancer patients, dependent on the localization (sentinel LN vs. non-sentinel LN), the tumor size, the intrinsic subtype and nodal metastatic status. The quantitative morphological study was conducted in breast cancer patients with at least one sentinel LN and no neoadjuvant therapy. All LNs were annotated considering to their topographical location, stained for IgD/H&E, digitized and quantitatively analyzed. In 206 patients, 394 sentinels and 940 non sentinel LNs were categorized, comprising 40758 follicles and 7074 germinal centers. Subtype specific immunomorphological patterns were detectable: Follicular density was higher in LNs of Her2 enriched hormone receptor positive and triple-negative breast cancers whereas hormone receptor positive breast cancers showed more macrophage infiltrations in the LN cortex. Follicles are rounder in metastatic LNs and non-sentinel LNs. The identified immunomorphological changes reflect different underlying immunomodulations taking place in the tumor-draining LNs and should therefore be considered as possible prognostic and predictive markers for LN metastasis and therapy associated immunomodulation. PMID- 29593309 TI - Cold Atmospheric Plasma Induces ATP-Dependent Endocytosis of Nanoparticles and Synergistic U373MG Cancer Cell Death. AB - Gold nanoparticles (AuNP) have potential as both diagnostic and therapeutic vehicles. However, selective targeting and uptake in cancer cells remains challenging. Cold atmospheric plasma (CAP) can be combined with AuNP to achieve synergistic anti-cancer cytotoxicity. To explore synergistic mechanisms, we demonstrate both rate of AuNP uptake and total amount accumulated in U373MG Glioblastoma multiforme (GBM) cells are significantly increased when exposed to 75 kV CAP generated by dielectric barrier discharge. No significant changes in the physical parameters of AuNP were caused by CAP but active transport mechanisms were stimulated in cells. Unlike many other biological effects of CAP, long-lived reactive species were not involved, and plasma-activated liquids did not replicate the effect. Chemical effects induced by direct and indirect exposure to CAP appears the dominant mediator of enhanced uptake. Transient physical alterations of membrane integrity played a minor role. 3D-reconstruction of deconvoluted confocal images confirmed AuNP accumulation in lysosomes and other acidic vesicles, which will be useful for future drug delivery and diagnostic strategies. Toxicity of AuNP significantly increased by 25-fold when combined with CAP. Our data indicate that direct exposure to CAP activates AuNP dependent cytotoxicity by increasing AuNP endocytosis and trafficking to lysosomes in U373MG cells. PMID- 29593310 TI - First insights of peptidoglycan amidation in Gram-positive bacteria - the high resolution crystal structure of Staphylococcus aureus glutamine amidotransferase GatD. AB - Gram-positive bacteria homeostasis and antibiotic resistance mechanisms are dependent on the intricate architecture of the cell wall, where amidated peptidoglycan plays an important role. The amidation reaction is carried out by the bi-enzymatic complex MurT-GatD, for which biochemical and structural information is very scarce. In this work, we report the first crystal structure of the glutamine amidotransferase member of this complex, GatD from Staphylococcus aureus, at 1.85 A resolution. A glutamine molecule is found close to the active site funnel, hydrogen-bonded to the conserved R128. In vitro functional studies using 1H-NMR spectroscopy showed that S. aureus MurT-GatD complex has glutaminase activity even in the absence of lipid II, the MurT substrate. In addition, we produced R128A, C94A and H189A mutants, which were totally inactive for glutamine deamidation, revealing their essential role in substrate sequestration and catalytic reaction. GatD from S. aureus and other pathogenic bacteria share high identity to enzymes involved in cobalamin biosynthesis, which can be grouped in a new sub-family of glutamine amidotransferases. Given the ubiquitous presence of GatD, these results provide significant insights into the molecular basis of the so far undisclosed amidation mechanism, contributing to the development of alternative therapeutics to fight infections. PMID- 29593311 TI - Mutations in the CDS and promoter of BjuA07.CLV1 cause a multilocular trait in Brassica juncea. AB - Multilocular trait has recently attracted considerable attention for its potential to increase yield. Our previous studies indicated that two genes (Bjln1 and Bjln2) are responsible for multilocular siliques in Brassica juncea and the Bjln1 gene has been delimited to a 208-kb region. In present study, the Bjln1 gene was successfully isolated using the map-based cloning method. Complementation test indicated that the BjuA07.CLV1 (equivalent to BjLn1) could rescue the multilocular phenotype and generate bilocular siliques. Two amino acids changes at positions 28 and 63 in BjuA07.clv1 as well as a 702-bp deletion in its promoter have been proved to affect the carpel numbers. Microscopic analyses suggested that BjuA07.CLV1 is involved in the maintenance of shoot and floral meristem size. The expression level of BjuA07.clv1 was significantly reduced in the SAM. Furthermore, WUS, CLV2, CLV3, RPK2 and POL, key genes in the CLV/WUS signal pathway, showed lower expression level in the multilocular plants. These data suggest that the mutations in the CDS and promoter of BjuA07.clv1 reduced its function and expression level, which disturbed CLV/WUS signal pathway, thereby leading to the enlargement of the shoot and floral meristem and resulting in the multilocular siliques. PMID- 29593312 TI - The sudden death and sudden birth of quantum discord. AB - The interaction of quantum system and its environment brings out abundant quantum phenomenons. The sudden death of quantum resources, including entanglement, quantum discord and coherence, have been studied from the perspective of quantum breaking channels (QBC). QBC of quantum resources reveal the common features of quantum resources. The definition of QBC implies the relationship between quantum resources. However, sudden death of quantum resources can also appear under some other quantum channels. We consider the dynamics of Bell-diagonal states under a stochastic dephasing noise along the z-direction, and the sudden death and sudden birth of quantum discord are investigated. Next we explain this phenomenon from the geometric structure of quantum discord. According to the above results, the states with sudden death and sudden birth can be filtered in three-parameter space. Then we provide two necessary conditions to judge which kind of noise channels can make Bell-diagonal states sudden death and sudden birth. Moreover, the relation between quantum discord and coherence indicates that the sudden death and sudden birth of quantum discord implies the sudden death and sudden birth of coherence in an optimal basis. PMID- 29593313 TI - Reduced Translocation of Glyphosate and Dicamba in Combination Contributes to Poor Control of Kochia scoparia: Evidence of Herbicide Antagonism. AB - Kochia scoparia is a troublesome weed across the Great Plains of North America. Glyphosate and dicamba have been used for decades to control K. scoparia. Due to extensive selection, glyphosate- and dicamba-resistant (GDR) K. scoparia have evolved in the USA. Herbicide mixtures are routinely used to improve weed control. Herbicide interactions if result in an antagonistic effect can significantly affect the management of weeds, such as K. scoparia. To uncover the interaction of glyphosate and dicamba when applied in combination in K. scoparia management the efficacies of different doses of glyphosate plus dicamba were evaluated under greenhouse and field conditions using GDR and a known glyphosate- and dicamba-susceptible (GDS) K. scoparia. The results of greenhouse and field studies suggest that the combination of glyphosate and dicamba application controlled GDS, but glyphosate alone provided a better control of GDR K. scoparia compared to glyphosate plus dicamba combinations. Furthermore, investigation of the basis of this response suggested glyphosate and dicamba interact antagonistically and consequently, the translocation of both herbicides was significantly reduced resulting in poor control of K. scoparia. Therefore, a combination of glyphosate plus dicamba may not be a viable option to control GDR K. scoparia. PMID- 29593315 TI - A Lethal Fungus Infects the Chinese White Wax Scale Insect and Causes Dramatic Changes in the Host Microbiota. AB - The Chinese white wax scale insect (Ericerus pela) is an economically valuable species with an important role in wax production. Recently, in a greenhouse in Kunming, we identified a genus of fungus that infects and kills E. pela females. This study sought to perform the molecular detection of entomopathogens and analyze the changes in the host microbiota after entomopathogen infection. We used library construction, high-throughput sequencing and real-time quantitative polymerase chain reaction (RT-qPCR) to identify the fungi infecting adult E. pela, to understand the changes in the host organism, and to determine the distribution of the entomopathogens. Cladosporium langeronii and C. sphaerospermum were the main pathogenic species that infected the E. pela females, and they were most prevalent in the dorsal cuticle. In vivo, after infection, the proportion of Cladosporium clearly increased. The infection had little influence on the fungal community but had a strong influence on the bacterial community. After infection, Arsenophonus was dominant, and numerous bacterial genera disappeared. However, Rickettsia, instead of Arsenophonus, became dominant in the Cladosporium-infected individuals that had also been infected with Rickettsia. We identified the species that infected E. pela females and determined the influence of infection on the host microorganisms. PMID- 29593314 TI - Oncofetal gene SALL4 reactivation by hepatitis B virus counteracts miR-200c in PD L1-induced T cell exhaustion. AB - A chronic viral or tumor microenvironment can push T cells to exhaustion by promoting coinhibitory ligand expression. However, how host factors control coinhibitory ligand expression and whether viral infection breaks this control during tumor progress is unknown. Here we show a close negative correlation between SALL4 or PD-L1 and miR-200c in tumors from 98 patients with HBV-related hepatocellular carcinoma. SALL4 or PD-L1 expression correlates negatively with miR-200c expression, and patients with lower levels of SALL4 or PD-L1 and higher miR-200c survive longer. Moreover, over-expression of miR-200c antagonizes HBV mediated PD-L1 expression by targeting 3'-UTR of CD274 (encoding PD-L1) directly, and reverses antiviral CD8+ T cell exhaustion. MiR-200c transcription is inhibited by oncofetal protein SALL4, which is re-expressed through HBV-induced STAT3 activation in adulthood. We propose that an HBV-pSTAT3-SALL4-miR-200c axis regulates PD-L1. Therapeutic strategies to influence this axis might reverse virus-induced immune exhaustion.

AB - Hippocampal network operations supporting spatial navigation and declarative memory are traditionally interpreted in a framework where each hippocampal area, such as the dentate gyrus, CA3, and CA1, consists of homogeneous populations of functionally equivalent principal neurons. However, heterogeneity within hippocampal principal cell populations, in particular within pyramidal cells at the main CA1 output node, is increasingly recognized and includes developmental, molecular, anatomical, and functional differences. Here we review recent progress in the delineation of hippocampal principal cell subpopulations by focusing on radially defined subpopulations of CA1 pyramidal cells, and we consider how functional segregation of information streams, in parallel channels with nonuniform properties, could represent a general organizational principle of the hippocampus supporting diverse behaviors.

AB - Activation of metastatic reprogramming is critical for tumour metastasis. However, more detailed knowledge of the underlying mechanism is needed to enable targeted intervention. Here, we show that paraspeckle component 1 (PSPC1), identified in an aberrant 13q12.11 locus, is upregulated and associated with poor survival in patients with cancer. PSPC1 promotes tumorigenesis, epithelial-to mesenchymal transition (EMT), stemness and metastasis in multiple cell types and in spontaneous mouse cancer models. PSPC1 is the master activator for transcription factors of EMT and stemness and accompanies c-Myc activation to facilitate tumour growth. PSPC1 increases transforming growth factor-beta1 (TGF beta1) secretion through an interaction with phosphorylated and nuclear Smad2/3 to potentiate TGF-beta1 autocrine signalling. Moreover, PSPC1 acts as a contextual determinant of the TGF-beta1 pro-metastatic switch to alter Smad2/3 binding preference from tumour-suppressor to pro-metastatic genes. Having validated the PSPC1-Smads-TGF-beta1 axis in various cancers, we conclude that PSPC1 is a master activator of pro-metastatic switches and a potential target for anti-metastasis drugs. PMID- 29593327 TI - Two succeeding fibroblastic lineages drive dermal development and the transition from regeneration to scarring. AB - During fetal development, mammalian back-skin undergoes a natural transition in response to injury, from scarless regeneration to skin scarring. Here, we characterize dermal morphogenesis and follow two distinct embryonic fibroblast lineages, based on their history of expression of the engrailed 1 gene. We use single-cell fate-mapping, live three dimensional confocal imaging and in silico analysis coupled with immunolabelling to reveal unanticipated structural and regional complexity and dynamics within the dermis. We show that dermal development and regeneration are driven by engrailed 1-history-naive fibroblasts, whose numbers subsequently decline. Conversely, engrailed 1-history-positive fibroblasts possess scarring abilities at this early stage and their expansion later on drives scar emergence. The transition can be reversed, locally, by transplanting engrailed 1-naive cells. Thus, fibroblastic lineage replacement couples the decline of regeneration with the emergence of scarring and creates potential clinical avenues to reduce scarring. PMID- 29593328 TI - Deconstructing the pluripotency gene regulatory network. AB - Pluripotent stem cells can be isolated from embryos or derived by reprogramming. Pluripotency is stabilized by an interconnected network of pluripotency genes that cooperatively regulate gene expression. Here we describe the molecular principles of pluripotency gene function and highlight post-transcriptional controls, particularly those induced by RNA-binding proteins and alternative splicing, as an important regulatory layer of pluripotency. We also discuss heterogeneity in pluripotency regulation, alternative pluripotency states and future directions of pluripotent stem cell research. PMID- 29593329 TI - TP53INP2 regulates adiposity by activating beta-catenin through autophagy dependent sequestration of GSK3beta. AB - Excessive fat accumulation is a major risk factor for the development of type 2 diabetes mellitus and other common conditions, including cardiovascular disease and certain types of cancer. Here, we identify a mechanism that regulates adiposity based on the activator of autophagy TP53INP2. We report that TP53INP2 is a negative regulator of adipogenesis in human and mouse preadipocytes. In keeping with this, TP53INP2 ablation in mice caused enhanced adiposity, which was characterized by greater cellularity of subcutaneous adipose tissue and increased expression of master adipogenic genes. TP53INP2 modulates adipogenesis through autophagy-dependent sequestration of GSK3beta into late endosomes. GSK3beta sequestration was also dependent on ESCRT activity. As a result, TP53INP2 promotes greater beta-catenin levels and induces the transcriptional activity of TCF/LEF transcription factors. These results demonstrate a link between autophagy, sequestration of GSK3beta into late endosomes and inhibition of adipogenesis in vivo. PMID- 29593330 TI - CK1alpha suppresses lung tumour growth by stabilizing PTEN and inducing autophagy. AB - The contribution of autophagy to cancer development remains controversial, largely owing to the fact that autophagy can be tumour suppressive or oncogenic in different biological contexts. Here, we show that in non-small-cell lung cancer (NSCLC), casein kinase 1 alpha 1 (CK1alpha) suppresses tumour growth by functioning as an autophagy inducer to activate an autophagy-regulating, tumour suppressive PTEN/AKT/FOXO3a/Atg7 axis. Specifically, CK1alpha bound the C terminal tail of PTEN and enhanced both PTEN stability and activity by competitively antagonizing NEDD4-1-induced PTEN polyubiquitination and abrogating PTEN phosphorylation, thereby inhibiting AKT activity and activating FOXO3a induced transcription of Atg7. Notably, blocking CK1alpha-induced Atg7-dependent autophagy cooperates with oncogenic HRasV12 to initiate tumorigenesis of lung epithelial cells. An association of a CK1alpha-modulated autophagic program with the anti-neoplastic activities of the CK1alpha/PTEN/FOXO3a/Atg7 axis was demonstrated in xenografted tumour models and human NSCLC specimens. This provides insights into the biological and potentially clinical significance of autophagy in NSCLC. PMID- 29593331 TI - GUARDIN is a p53-responsive long non-coding RNA that is essential for genomic stability. AB - The list of long non-coding RNAs (lncRNAs) involved in the p53 pathway of the DNA damage response is rapidly expanding, but whether lncRNAs have a role in maintaining the de novo structure of DNA is unknown. Here, we demonstrate that the p53-responsive lncRNA GUARDIN is important for maintaining genomic integrity under steady-state conditions and after exposure to exogenous genotoxic stress. GUARDIN is necessary for preventing chromosome end-to-end fusion through maintaining the expression of telomeric repeat-binding factor 2 (TRF2) by sequestering microRNA-23a. Moreover, GUARDIN also sustains breast cancer 1 (BRCA1) stability by acting as an RNA scaffold to facilitate the heterodimerization of BRCA1 and BRCA1-associated RING domain protein 1 (BARD1). As such, GUARDIN silencing triggered apoptosis and senescence, enhanced cytotoxicity of additional genotoxic stress and inhibited cancer xenograft growth. Thus, GUARDIN may constitute a target for cancer treatment. PMID- 29593332 TI - The importance of a potential phosphorylation site in enamelin on enamel formation. AB - Enamelin (ENAM) has three putative phosphoserines (pSers) phosphorylated by a Golgi-associated secretory pathway kinase (FAM20C) based on their distinctive Ser x-Glu (S-x-E) motifs. Fam20C-knockout mice show severe enamel defects similar to those in the Enam-knockout mice, implying an important role of the pSers in ENAM. To determine the role of pSer55 in ENAM, we characterized ENAMRgsc514 mice, in which Ser55 cannot be phosphorylated by FAM20C due to an E57>G57 mutation in the S-x-E motif. The enamel microstructure of 4-week-old mice was examined by scanning electron microscopy. The teeth of 6-day-old mice were characterized by histology and immunohistochemistry. The protein lysates of the first lower molars of 4-day-old mice were analyzed by Western immunoblotting using antibodies against ENAM, ameloblastin and amelogenin. ENAMRgsc514 heterozygotes showed a disorganized enamel microstructure, while the homozygotes had no enamel on the dentin surface. The N-terminal fragments of ENAM in the heterozygotes were detained in the ameloblasts and localized in the mineralization front of enamel matrix, while those in the WT mice were secreted out of ameloblasts and distributed evenly in the outer 1/2 of enamel matrix. Surprisingly, the ~15 kDa C-terminal fragments of ameloblastin were not detected in the molar lysates of the homozygotes. These results suggest that the phosphorylation of Ser55 may be an essential posttranslational modification of ENAM and is required for the interaction with other enamel matrix molecules such as ameloblastin in mediating the structural organization of enamel matrix and protein-mineral interactions during enamel formation.International Journal of Oral Science (2017) 9;e4; doi:10.1038/ijos.2017.41; published online 29 November 2017. PMID- 29593333 TI - Schottky model for triboelectric temperature dependence. AB - The triboelectric effect, charging by contact, is the working principle in a device called a triboelectric nanogenerator. They are used as efficient energy transducers in energy harvesting. In such generators the charging of surfaces at contact is followed by a separation of the surfaces increasing the electrical energy which can subsequently be used. Different materials have different triboelectric potentials leading to charging at contact. The temperature dependence of the charging has just recently been studied: the triboelectric effect is decreasing with temperature for a generator of Al-PTFE-Cu. Here, we suggest a mechanism to explain this effect assuming ion transfer using a two level Schottky model where the two levels corresponds to the two surfaces. The difference in binding energy for ions on the two surfaces then enters the formula for charging. We fit the triboelectric power density as a function of temperature obtained from a two-level Schottky model to measured data for nanogenerators made of Al-PTFE-Cu found in three references. We obtain an average separation energy corresponding to a temperature of 365 K which is of the right magnitude for physically adsorbed atoms. We anticipate that this model could be used for many types of triboelectric nanogenerators. PMID- 29593334 TI - USP15-dependent lysosomal pathway controls p53-R175H turnover in ovarian cancer cells. AB - Gain-of-function p53 mutants such as p53-R175H form stable aggregates that accumulate in cells and play important roles in cancer progression. Selective degradation of gain-of-function p53 mutants has emerged as a highly attractive therapeutic strategy to target cancer cells harboring specific p53 mutations. We identified a small molecule called MCB-613 to cause rapid ubiquitination, nuclear export, and degradation of p53-R175H through a lysosome-mediated pathway, leading to catastrophic cancer cell death. In contrast to its effect on the p53-R175H mutant, MCB-613 causes slight stabilization of p53-WT and has weaker effects on other p53 gain-of-function mutants. Using state-of-the-art genetic and chemical approaches, we identified the deubiquitinase USP15 as the mediator of MCB-613's effect on p53-R175H, and established USP15 as a selective upstream regulator of p53-R175H in ovarian cancer cells. These results confirm that distinct pathways regulate the turnover of p53-WT and the different p53 mutants and open new opportunities to selectively target them. PMID- 29593335 TI - Differences in cognitive functions between cytomegalovirus-infected and cytomegalovirus-free university students: a case control study. AB - Cytomegalovirus (CMV) is the herpetic virus, which infects 45-100% people worldwide. Many reports suggest that CMV could impair cognitive functions of infected subjects. Here we searched for indices of effects of CMV on infected subjects' intelligence and knowledge. The Intelligence Structure Test I-S-T 2000 R was used to compare IQ of 148 CMV-infected and 135 CMV-free university students. Infected students expressed higher intelligence. Paradoxically, their IQ decreased with decreasing concentration of anti-CMV antibodies, which can be used, statistically, as a proxy of the time passed from the moment of infection in young subjects when the age of subjects is statistically controlled. The paradox of seemingly higher intelligence of CMV infected subjects could be explained by the presence of the subpopulation of about 5-10% CMV-positive individuals in the population of "CMV-negative students". These false negative subjects had probably not only the oldest infections and therefore the lowest concentration of anamnestic antibodies, but also the lowest intelligence among the infected students. Prevalence of CMV infection in all countries is very high, approaching sometimes 90%. Therefore, the total impact of CMV on human intelligence may be large. PMID- 29593336 TI - Germline mutations as potential causes of childhood solid tumours: comments on the Norwegian childhood cancer cohort study. AB - Some cancer predisposing germline mutations cause overt birth defects and congenital anomalies. Others are clinically silent and can only be suspected by the presence of increased cancer incidence in family members. A new study shows that long-term monitoring of families may be needed to discover previously unsuspected underlying cancer predisposing mutations. PMID- 29593337 TI - End-of-life decision-making across cancer types: results from a nationwide retrospective survey among treating physicians. AB - BACKGROUND: The treatment of advanced cancer often involves potentially life shortening end-of-life decisions (ELDs). This study aimed to examine the prevalence and characteristics of ELDs in different cancer types. METHODS: A nationwide death certificate study was conducted based on a large random sample of all deaths in Flanders, Belgium, between 1 January and 30 June 2013. All cancer deaths were selected (n = 2392). Attending physicians were sent a questionnaire about ELDs and the preceding decision-making process. RESULTS: The response rate was 58.3%. Across cancer types, a non-treatment decision occurred in 7.6-14.0%, intensified pain and symptom alleviation in 37.5-41.7%, euthanasia or physician-assisted suicide in 8.7-12.6%, and life shortening without explicit patient request in 1.0-2.4%. ELD prevalence did not differ significantly by cancer type. Reasons for ELDs were most frequently patient's physical suffering and lack of prospect of improvement. 'Anticipated further suffering' and 'unbearable situation for relatives' were reasons more often reported in haematological cancer than in other cancer types. Patient, family, and caregiver involvement in decision-making did not differ across cancer types. CONCLUSIONS: Euthanasia or physician-assisted suicide rates were relatively high in all cancer types. Neither the prevalence of ELDs nor characteristics of the decision-making process differed substantially between cancer types. This indicates a uniform approach to end-of-life care, including palliative care, across oncological settings. PMID- 29593338 TI - The effect of selection and referral biases for the treatment of localised prostate cancer with surgery or radiation. AB - BACKGROUND: Consultation with radiation oncologists, in addition to urologists, is advocated for patients diagnosed with prostate cancer. Treatment patterns for patients receiving consultation from radiation oncologists in addition to urologists have not previously been described. METHODS: We conducted a matched cohort study of men with newly diagnosed non-metastatic prostate cancer in Ontario, Canada. Patients who underwent consultation with a radiation oncologist prior to treatment were matched 1:1 with patients managed by a urologist alone based on tumour and patient characteristics. We examined rates of active treatment (surgery or radiotherapy) within one year following diagnosis. RESULTS: Among 5708 matched pairs (11,416 patients), those who received radiation oncology consultation were more likely to undergo active treatments whether they had intermediate or high-risk disease (88.6% vs. 65.9%, p < 0.0001; adjusted odds ratio 4.0, 95% CI: 3.6-4.4) or low-risk disease (56.1% vs. 13.3%, p < 0.0001; adjusted odds ratio 8.4, 95% CI: 6.7-10.6). This effect persisted after considering age, comorbidity, tumour volume and year of diagnosis. CONCLUSIONS: Patients newly diagnosed with prostate cancer who receive radiation oncology consultation are associated with a higher rate of active treatment, compared to patients managed by urologists only. Selection and referral biases, and unmeasured confounding such as patient preference must be considered as important factors attributing this association. PMID- 29593340 TI - Anti-CTLA-4 immunotherapy: uncoupling toxicity and efficacy. PMID- 29593339 TI - Quantitative proteomic profiling of primary cancer-associated fibroblasts in oesophageal adenocarcinoma. AB - BACKGROUND: Cancer-associated fibroblasts (CAFs) form the major stromal component of the tumour microenvironment (TME). The present study aimed to examine the proteomic profiles of CAFs vs. normal fibroblasts (NOFs) from patients with oesophageal adenocarcinoma to gain insight into their pro-oncogenic phenotype. METHODS: CAFs/NOFs from four patients were sub-cultured and analysed using quantitative proteomics. Differentially expressed proteins (DEPs) were subjected to bioinformatics and compared with published proteomics and transcriptomics datasets. RESULTS: Principal component analysis of all profiled proteins showed that CAFs had high heterogeneity and clustered separately from NOFs. Bioinformatics interrogation of the DEPs demonstrated inhibition of adhesion of epithelial cells, adhesion of connective tissue cells and cell death of fibroblast cell lines in CAFs vs. NOFs (p < 0.0001). KEGG pathway analysis showed a significant enrichment of the insulin-signalling pathway (p = 0.03). Gene ontology terms related with myofibroblast phenotype, metabolism, cell adhesion/migration, hypoxia/oxidative stress, angiogenesis, immune/inflammatory response were enriched in CAFs vs. NOFs. Nestin, a stem-cell marker up-regulated in CAFs vs. NOFs, was confirmed to be expressed in the TME with immunohistochemistry. CONCLUSIONS: The identified pathways and participating proteins may provide novel insight on the tumour-promoting properties of CAFs and unravel novel adjuvant therapeutic targets in the TME. PMID- 29593341 TI - MLL5 suppresses antiviral innate immune response by facilitating STUB1-mediated RIG-I degradation. AB - Trithorax group protein MLL5 is an important epigenetic modifier that controls cell cycle progression, chromatin architecture maintenance, and hematopoiesis. However, whether MLL5 has a role in innate antiviral immunity is largely unknown. Here we show that MLL5 suppresses the RIG-I-mediated anti-viral immune response. Mll5-deficient mice infected with vesicular stomatitis virus show enhanced anti viral innate immunity, reduced morbidity, and viral load. Mechanistically, a fraction of MLL5 located in the cytoplasm interacts with both RIG-I and its E3 ubiquitin ligase STUB1, which promotes K48-linked polyubiquitination and proteasomal degradation of RIG-I. MLL5 deficiency attenuates the RIG-I and STUB1 association, reducing K48-linked polyubiquitination and accumulation of RIG-I protein in cells. Upon virus infection, nuclear MLL5 protein translocates from the nucleus to the cytoplasm inducing STUB1-mediated degradation of RIG-I. Our study uncovers a previously unrecognized role for MLL5 in antiviral innate immune responses and suggests a new target for controlling viral infection. PMID- 29593342 TI - Genetic variants and pathways implicated in a pediatric inflammatory bowel disease cohort. AB - In the United States, approximately 5% of individuals with inflammatory bowel disease (IBD) are younger than 20 years old. Studies of pediatric cohorts can provide unique insights into genetic architecture of IBD, which includes Crohn's disease (CD) and ulcerative colitis (UC). Large genome-wide association studies have found more than 200 IBD-associated loci but explain a minority of disease variance for CD and UC. We sought to characterize the contribution of rare variants to disease development, comparing exome sequencing of 368 pediatric IBD patients to publicly available exome sequencing (dbGaP) and aggregate frequency data (ExAC). Using dbGaP data, we performed logistic regression for common variants and optimal unified association tests (SKAT-O) for rare, likely deleterious variants. We further compared rare variants to ExAC counts with Fisher's exact tests. We did pathway enrichment analysis on the most significant genes from each comparison. Many variants overlapped with known IBD-associated genes (e.g. NOD2). Rare variants were enriched in CD-associated loci (p = 0.009) and showed suggestive enrichment in neutrophil function genes (p = 0.05). Pathway enrichment implicated immune-related pathways, especially cell killing and apoptosis. Variants in extracellular matrix genes also emerged as an important theme in our analysis. PMID- 29593343 TI - Treatment in myositis. AB - As with the treatment of many immune-mediated diseases, managing myositis encompasses diverse factors, which present a challenge to the physician caring for these patients. The idiopathic inflammatory myopathies (IIMs, also known as myositis), are fundamentally heterogeneous; many contributory immunological perturbations are involved in the pathogenesis of myositis, leading to varying clinical phenotypic presentations. Targeting any one or several of these deleterious pathways with a therapeutic agent might seem reasonable, but the desired response is not uniformly predictable. The presence of many serious extramuscular manifestations, such as severe skin rash, interstitial lung disease and arthritis, complicates the management of myositis. Myositis is rare, and very few large treatment trial results are available to guide clinicians. Outcome measures to effectively gauge treatment responses have been available for only a few years, and response criteria that incorporate critical core set measures continue to evolve. Nevertheless, a multitude of immunosuppressive and immunomodulatory agents are available to clinicians managing myositis, and the emergence of biologic agents targeting potential pathogenic pathways offers hope for mitigating or curing this enigmatic group of diseases. Paradigm shifts in the nonpharmacological approach to treat myositis have also occurred as more aggressive exercise regimens have shown benefit in patients, even those with active disease.

AB - BACKGROUND/OBJECTIVES: Undernutrition is a frequent condition among hospitalized patients, with a significant impact on patient's outcome and hospital costs. Whether undernutrition is reported similarly at the national level has seldom been assessed. We aimed to (1) assess regional differences within Switzerland regarding undernutrition prevalence, management, and cost reimbursement and (2) identify the factors associated with reporting of undernutrition status and its management. SUBJECTS/METHODS: Observational cross-sectional study including routine statistics from the Swiss hospital discharge databases for years 2013 and 2014 (seven administrative regions). All adults aged >=20 with length of hospital stay of at least 1 day was included. Reported undernutrition was defined based on the International Classification of Diseases (ICD)-10 codes. Nutritional management and "reimbursable" undernutrition codes were also assessed. RESULTS: Of the initial 1,784,855 hospitalizations, 3.6% had reported undernutrition, the prevalence ranging between 1.8% (Ticino) and 4.6% (Mittelland). Use of different undernutrition-related ICD-10 codes also varied considerably across regions. Multivariable analysis showed a twofold variation in reported undernutrition: multivariable-adjusted odds ratio and 95% confidence interval relative to Eastern Switzerland: 2.31 (2.23, 2.38) for Mittelland and 0.74 (0.70, 0.79) for Ticino. Over half (59.6%) of hospitalizations with reported undernutrition also included information on undernutrition management, ranging between 28.6% (Ticino) and 67.2% (Zurich). Only one third (36.8%) of undernutrition-related codes were reimbursable, ranging between 8.3% (Ticino) and 50.7% (Zurich). CONCLUSIONS: In Switzerland, there is considerable regional variation regarding reporting of undernutrition prevalence, management, and cost reimbursement. Undernutrition appears to be insufficiently managed and valued. PMID- 29593344 TI - Characterization of Split Fluorescent Protein Variants and Quantitative Analyses of Their Self-Assembly Process. AB - Many biotechniques use complementary split-fluorescent protein (sFPs) fragments to visualize protein-protein interactions, image cells by ensemble or single molecule fluorescence microscopy, or assemble nanomaterials and protein superstructures. Yet, the reassembly mechanisms of sFPs, including fragment binding rates, folding, chromophore maturation and overall photophysics remain poorly characterized. Here, we evolved asymmetric and self-complementing green, yellow and cyan sFPs together with their full-length equivalents (flFPs) and described their biochemical and photophysical properties in vitro and in cells. While re-assembled sFPs have spectral properties similar to flFPs, they display slightly reduced quantum yields and fluorescence lifetimes due to a less sturdy beta-barrel structure. The complementation of recombinant sFPs expressed in vitro follows a conformational selection mechanism whereby the larger sFP fragments exist in a monomer-dimer equilibrium and only monomers are competent for fluorescence complementation. This bimolecular fragment interaction involves a slow and irreversible binding step, followed by chromophore maturation at a rate similar to that of flFPs. When expressed as fusion tags in cells, sFPs behave as monomers directly activated with synthetic complementary fragments. This study resulted in the development of sFP color variants having improved maturation kinetics, brightness, and photophysics for fluorescence microscopy imaging of cellular processes, including single molecule detection. PMID- 29593347 TI - The direct and indirect associations of usual free sugar intake on BMI z-scores of Australian children and adolescents. AB - This cross-sectional analysis aimed to assess the association between free sugar consumption and the BMI z-score of Australian children and adolescents. Data from the 2007 Australian National Children's Nutrition and Physical Activity Survey were analyzed. Structural equation modeling was used to assess the direct association between usual free sugar intake and age-and-sex-specific BMI z-score, and the indirect association mediated via energy overconsumption. Weak and statistically non-significant associations were found for the direct (BMI z-score beta = -0.02 per 10% change in energy intake from free sugar, p = 0.705) and indirect pathways (BMI z-score beta = -0.04 per 10% change in energy intake from free sugar, p = 0.705). We concluded that free sugar intake was not associated with BMI z-score in this cohort. Instead of focusing on a single energy source in the diet, improving the quality of the whole diet may be a better approach in tackling childhood obesity. PMID- 29593348 TI - Profiles of miRNA Isoforms and tRNA Fragments in Prostate Cancer. AB - MicroRNA (miRNA) isoforms ("isomiRs") and tRNA-derived fragments ("tRFs") are powerful regulatory non-coding RNAs (ncRNAs). In human tissues, both types of molecules are abundant, with expression patterns that depend on a person's race, sex and population origin. Here, we present our analyses of the Prostate Cancer (PRAD) datasets of The Cancer Genome Atlas (TCGA) from the standpoint of isomiRs and tRFs. This study represents the first simultaneous examination of isomiRs and tRFs in a large cohort of PRAD patients. We find that isomiRs and tRFs have extensive correlations with messenger RNAs (mRNAs). These correlations are disrupted in PRAD, which suggests disruptions of the regulatory network in the disease state. Notably, we find that the profiles of isomiRs and tRFs differ in patients belonging to different races. We hope that the presented findings can lay the groundwork for future research efforts aimed at elucidating the functional roles of the numerous and distinct members of these two categories of ncRNAs that are present in PRAD. PMID- 29593349 TI - Tlr1612 is the major repressor of cell aggregation in the light-color-dependent c di-GMP signaling network of Thermosynechococcus vulcanus. AB - Cyclic diguanylate (c-di-GMP) is a bacterial second messenger involved in sessile/motile lifestyle transitions. We previously reported that c-di-GMP is a crucial inducer of cell aggregation of the cyanobacterium Thermosynechococcus vulcanus. The three cooperating cyanobacteriochrome photoreceptors (SesA/B/C) regulate cell aggregation in a light color-dependent manner by synthesizing/degrading c-di-GMP. Although a variety of c-di-GMP signaling proteins are encoded in cyanobacterial genomes, how c-di-GMP signaling networks are organized remains elusive. Here we experimentally demonstrate that the cellulose synthase Tll0007, which is essential for cell aggregation, binds c-di GMP although the affinity is low (Kd = 63.9 +/- 5.1 uM). We also show that SesA the main trigger of cell aggregation-is subject to strict product feedback inhibition (IC50 = 1.07 +/- 0.13 uM). These results suggest that SesA-produced c di-GMP may not directly bind to Tll0007. We therefore systematically analyzed all 10 of the genes encoding proteins containing a c-di-GMP synthesis/degradation domain. We identified Tlr1612, harboring both domains, as the major repressor of cell aggregation under the repressing teal-green light irradiation. tlr1612 acts downstream of sesA and is not regulated transcriptionally by light color, suggesting that Tlr1612 may be involved in c-di-GMP amplification in the signaling cascade. Post-transcriptional control is likely crucial for the light regulated c-di-GMP signaling. PMID- 29593350 TI - Elucidation of the bacterial communities associated with the harmful microalgae Alexandrium tamarense and Cochlodinium polykrikoides using nanopore sequencing. AB - Interactions between microalgae and bacteria are often obligatory for harmful algal blooms (HABs). Here, we investigated the specific bacterial communities associated with Alexandrium tamarense and Cochlodinium polykrikoides, which cause ecological and economic damage during their blooms. To this end, the bacterial metagenome was selectively isolated from the two dinoflagellates and subsequently used for 16S rRNA analysis via the Nanopore MinION and Illumina sequencing platforms. Although the full-length 16S rRNA reads from the MinION platform showed high correlation in higher taxonomic ranks to the partial-length 16S rRNA reads from the Illumina platform, there was less correlation at the genus and species levels. MinION reads that are similar in the V3-V4 hypervariable regions with Illumina reads are classified to different taxonomies due to the extra information encoded in the full-length 16S rRNA reads. This indicates that bias arising from the short length Illumina reads can be supplemented by MinION reads. Furthermore, integrated analysis of the Illumina and MinION data showed that A. tamarense was predominantly enriched in the Roseobacter clade and C. polykrikoides was enriched in Gammaproteobacteria and Alphaproteobacteria. These results suggest that the association of different bacterial communities with A. tamarense and C. polykrikoides may be required for HABs. PMID- 29593351 TI - "Possibly positive or certainly uncertain?": participants' responses to uncertain diagnostic results from exome sequencing. AB - PurposeClinical genome sequencing produces uncertain diagnostic results, raising concerns about how to communicate the method's inherent complexities in ways that reduce potential misunderstandings and harm. This study investigates clinicians' communications and patient/participant responses to uncertain diagnostic results arising from a clinical exome sequencing research study, contributing empirical data to the debate surrounding disclosure of uncertain genomic information.MethodsWe investigated the communication and impact of uncertain diagnostic results using ethnographic observations of result disclosures with 21 adults and 11 parents of child patients, followed by two semistructured interviews with these same participants.ResultsParticipants understood their uncertain results in ways that were congruent with clinical geneticists' communications. They followed recommendations for further consultation, although family testing to resolve uncertainty was not always done. Participants were prepared for learning an uncertain result and grasped the key concept that it should not be used to guide health-care or other decisions. They did not express regret for having learned the uncertain result; most regarded it as potentially valuable in the future.ConclusionThis study suggests that uncertain diagnostic results from genome sequencing can be relayed to patients in ways they can understand and consistent with providers' interpretations, without causing undue harm. PMID- 29593354 TI - Ultra-fast responsive colloidal-polymer composite-based volatile organic compounds (VOC) sensor using nanoscale easy tear process. AB - There is an immense need for developing a simple, rapid, and inexpensive detection assay for health-care applications or monitoring environments. To address this need, a photonic crystal (PC)-based sensor has been extensively studied due to its numerous advantages such as colorimetric measurement, high sensitivity, and low cost. However, the response time of a typical PC-based sensor is relatively slow due to the presence of the inevitable upper residual layer in colloidal structures. Hence, we propose an ultra-fast responsive PC based volatile organic compound (VOC) sensor by using a "nanoscale easy tear (NET) process" inspired by commercially available "easy tear package". A colloidal crystal-polydimethylsiloxane (PDMS) composite can be successfully realized through nanoscale tear propagation along the interface between the outer surface of crystallized nanoparticles and bulk PDMS. The response time for VOC detection exhibits a significant decrease by allowing the direct contact with VOCs, because of perfect removal of the residual on the colloidal crystals. Moreover, vapor-phase VOCs can be monitored, which had been previously impossible. High-throughput production of the patterned colloidal crystal-polymer composite through the NET process can be applied to other multiplexed selective sensing applications or may be used for nanomolding templates. PMID- 29593355 TI - Severe maternal morbidity and related hospital quality measures in Maryland. AB - OBJECTIVE: To determine hospital characteristics and quality metrics associated with severe maternal morbidity (SMM) in Maryland. STUDY DESIGN: A population based observational study of 364,113 statewide delivery hospitalizations during 2010-2015 linked with socio-economic community measures and hospital characteristics and quality measures. Multivariable logistic regression models with generalized estimating equations estimated SMM adjusting for individual, community, and hospital-level factors and clustering within hospitals and residence zip codes. RESULTS: The SMM prevalence was 197 per 10,000 deliveries. Adjusted SMM risk ratios were higher for younger (<20 years), older (35+ years), non-White non-Hispanic, unmarried, multiple substance users, women with multiple gestations, and chronic medical and mental health conditions than their counterparts. Communities with greater socio-economic disadvantage and hospitals with poorer patient experience and clinical care quality had higher rates of SMM. CONCLUSION: Addressing socio-economic disparities and improving quality of care in delivery hospitals are key to reducing the SMM burden in Maryland.

AB - OBJECTIVE: To identify key features in the NICU care delivery context that influence quality of care delivery. STUDY DESIGN: Qualitative study using in depth, semi-structured interviews with 10 NICU quality experts with extensive experience conducting NICU site visits and evaluating quality of care. Analyses were performed using the method of constant comparison based on grounded theory. RESULTS: Qualitative analysis yielded three major themes: (1) the foundation for high quality care is a cohesive unit culture, characterized by open communication, teamwork, and engagement of families; (2) effective linkages between measurement and improvement action is necessary for continuous improvement; and (3) NICU capacity for improvement is sustained by active support, exchange of skills, and resources from the hospital. CONCLUSIONS: Team cohesion, engagement of families, culture of improvement supported by measurement and institutional support from the hospital are some of the key contextual and managerial features critical to high-quality NICU care. PMID- 29593357 TI - Patterns of acute bilirubin encephalopathy in Nigeria: a multicenter pre intervention study. AB - BACKGROUND: Acute bilirubin encephalopathy (ABE) is an important cause of neonatal morbidity in Nigeria, accounting for 5-14% of neonatal deaths. Most newborns with severe ABE have irreversible damage before receiving treatment emphasizing the need for timely pre-admission monitoring and referral. There is limited evidence that educational interventions targeting mothers and health care providers will reduce delayed care. OBJECTIVE: To provide baseline data on the incidence of ABE and associated pre-admission risk factors in five centers of Nigeria in order to evaluate the effect of subsequent educational interventions on outcome. STUDY DESIGN: The incidence of ABE among newborns treated for hyperbilirubinemia was documented prospectively. Bivariate analysis and multivariate logistic regression were used to evaluate risk factors for acute bilirubin encephalopathy and reasons for regional differences in its occurrence. RESULTS: Of 1040 infants, 159 treated for hyperbilirubinemia (15.3%) had mild to severe bilirubin encephalopathy (including 35 deaths), but the incidence ranged from 7 to 22% between centers. Logistic regression identified four common predictors: total serum bilirubin (odds ratio 1.007 per mg/dl rise), out-of hospital births (OR 2.6), non-alloimmune hemolytic anemia (OR 2.8), and delayed care seeking (OR 4.3). CONCLUSION: The high occurrence of bilirubin encephalopathy in Nigeria is due in large part to a delay in seeking care. A planned intervention strategy will target conditions leading to severe hyperbilirubinemia and delay. PMID- 29593358 TI - Antitumor effect of antibiotic resistance gene-free plasmids encoding interleukin 12 in canine melanoma model. AB - The electrotransfer of interleukin-12 (IL-12) has been demonstrated as an efficient and safe treatment for tumors in veterinary oncology. However, the plasmids used encode human or feline IL-12 and harbor the gene for antibiotic resistance. Therefore, our aim was to construct plasmids encoding canine IL-12 without the antibiotic resistance genes driven by two different promoters: constitutive and fibroblast-specific. The results obtained in vitro in different cell lines showed that following gene electrotransfer, the newly constructed plasmids had cytotoxicity and expression profiles comparable to plasmids with antibiotic resistance genes. Additionally, in vivo studies showed a statistically significant prolonged tumor growth delay of CMeC-1 tumors compared to control vehicle-treated mice after intratumoral gene electrotransfer. Besides the higher gene expression obtained by plasmids with constitutive promoters, the main difference between both plasmids was in the distribution of the transgene expression. Namely, after gene electrotransfer, plasmids with constitutive promoters showed an increase of serum IL-12, whereas the gene expression of IL 12, encoded by plasmids with fibroblast-specific promoters, was restricted to the tumor. Furthermore, after the gene electrotransfer of plasmids with constitutive promoters, granzyme B-positive cells were detected in the tumor and spleen, indicating a systemic effect of the therapy. Therefore, plasmids with different promoters present valuable tools for focused therapy with local or systemic effects. The results of the present study demonstrated that plasmids encoding canine IL-12 under constitutive and fibroblast-specific promoters without the gene for antibiotic resistance provide feasible tools for controlled gene delivery that could be used for the treatment of client-owned dogs. PMID- 29593359 TI - Magnetic nanoparticle-mediated gene therapy to induce Fas apoptosis pathway in breast cancer. AB - CD95 (Fas) is a complex integral protein that can be expressed in many cells. It induces apoptosis when interacted with its ligand CD95L (FasL). However, cancer cells are resistant to CD95-induced apoptosis because of the changes in death domain (DD) of CD95 (procaspase-8 and c-Flip). In this study, magnetic nanoparticles and lipid-based gene transfection methods were performed to provide active Fas expression in breast cancer cells. Plasmid DNA (pDNA), which can express both human Fas and GFP, was transfected to MCF-7 breast cancer cells. Expression of c-FLIP and caspase-8 and effect of monoclonal antibody FasL for apoptosis stimulation were investigated. Also transfection success of methods and effects on surface protein were compared. Western blot results indicated that MCF 7 cells do not express caspase-8 but express large amount of c-FLIPL. Both lipid based and magnetic nanoparticle-mediated gene transfection methods successfully applied. Caspase-8 apoptosis pathway was activated on transfected cells. Magnetic nanoparticle-mediated gene transfer is a successful non-viral method for transfection, and it does not affect the expression of other cell proteins, such as beta actin and lamin-B1. The raised c-FLIPL concentration in cytosol inhibits apoptosis. However, transfection of CD95-GFP-tagged pDNA significantly increases apoptosis by activating caspase-8 pathway. FasL interaction indicated a slight increase of apoptosis in the transfected cells. The method and pDNA applied in this study have potentials to be used in gene therapy for breast cancer.

AB - It is often possible to retrace the history of a new concept or a new technique, identifying precursor and reflections that would lay the foundations for the birth of something "new". This also applies to the "squiggle game" of Donald W. Winnicott, one of the Winnicottian "creations" in which the distinctive signs of its fatherhood are more evident as, at the same time, are evident several debts to other scientists: from Freud's interpretation of dreams, through Jung, Klein and Fordham to Milner's "free drawings".

AB - Joseph Halpern and Judea Pearl ([2005]) draw upon structural equation models to develop an attractive analysis of 'actual cause'. Their analysis is designed for the case of deterministic causation.

Current perspectives are not capable of answering interdisciplinary adaptation and mitigation challenges posed by increases in wildfire risk to human populations and the need to reintegrate fire as a vital landscape process. Fire science has been, and continues to be, performed in isolated "silos," including institutions (e.g., agencies versus universities), organizational structures (e.g., federal agency mandates versus local and state procedures for responding to fire), and research foci (e.g., physical science, natural science, and social science). These silos tend to promote research, management, and policy that focus only on targeted aspects of the "wicked" wildfire problem. In this article, we provide guiding principles to bridge diverse fire science efforts to advance an integrated agenda of wildfire research that can help overcome disciplinary silos and provide insight on how to build fire-resilient communities. PMID- 29593363 TI - Political Ideology, Trust, and Cooperation: In-group Favoritism among Republicans and Democrats during a US National Election. AB - Theories suggest that political ideology relates to cooperation, with conservatives being more likely to pursue selfish outcomes, and liberals more likely to pursue egalitarian outcomes. In study 1, we examine how political ideology and political party affiliation (Republican vs. Democrat) predict cooperation with a partner who self-identifies as Republican or Democrat in two samples before (n = 362) and after (n = 366) the 2012 US presidential election. Liberals show slightly more concern for their partners' outcomes compared to conservatives (study 1), and in study 2 this relation is supported by a meta analysis (r = .15). However, in study 1, political ideology did not relate to cooperation in general. Both Republicans and Democrats extend more cooperation to their in-group relative to the out-group, and this is explained by expectations of cooperation from in-group versus out-group members. We discuss the relation between political ideology and cooperation within and between groups.

PMID- 29593365 TI - (How) Does Obesity Harm Academic Performance? Stratification at the Intersection of Race, Sex, and Body Size in Elementary and High School. AB - In this study I hypothesize a larger penalty of obesity on teacher-assessed academic performance for white girls in English, where femininity is privileged, than in math, where stereotypical femininity is perceived to be a detriment. This pattern of associations would be expected if obesity largely influences academic performance through social pathways such as discrimination and stigma. In the Fragile Families and Child Wellbeing Study (~age 9) and the National Longitudinal Study of Youth 1997 (~age 18), I find obesity to be associated with a penalty on academic performance among white girls in English but not in math, while no association is found in either subject for white boys or for black students net of controls. Findings suggest that the relationship between obesity and academic performance may result largely from how educational institutions interact with bodies of different sizes, rather than primarily via constraints on physical health. PMID- 29593366 TI - The Emergence of Two Distinct Fertility Regimes in Economically Advanced Countries. AB - Beginning in 2000, in economically advanced countries, a remarkable bifurcation in fertility levels has emerged, with one group in the moderate range of period total fertility rates (TFR), about 1.9, and the other at 1.3. The upper branch consists of countries in Northern and Western Europe, Oceania and the United States; the lower branch includes Central, Southern and Eastern Europe, and East and Southeast Asia. A review of the major theories for low fertility countries reveals that none of them would have predicted this specific bifurcation. We argue that those countries with fertility levels close to replacement level have institutional arrangements, and related policies, that make it easier, not easy, for women to combine the worker and mother roles. The institutional details are quite different across countries, suggesting that multiple combinations of institutional arrangements and policies can lead to the same country-level fertility outcome. Canada, the only exception to this bifurcation, illustrates the importance of the different institutional structures in Quebec compared to the rest of Canada. PMID- 29593367 TI - A Case for "Reverse One-Child" Policies in Japan and South Korea? Examining the Link between Education Costs and Lowest-Low Fertility. AB - Household spending on children's pre-tertiary education is exceptionally high in Japan and South Korea, and has been cited as a cause of low fertility. Previous research attributes this high spending to a cultural emphasis on education in East Asian countries. In this paper, we argue that institutional factors, namely higher education and labor market systems, play an important role in reinforcing the pressure on parents to invest in their children's education. We review evidence showing that graduating from a prestigious university has very high economic and social returns in Japan and South Korea, and examine the implications for fertility within the framework of quantity-quality models. Finally, we put forward 'reverse one-child' policies that directly address the unintended consequences of these institutional factors on fertility. These policies have the additional virtues of having very low fiscal requirements and reducing social inequality. PMID- 29593368 TI - Man enough? Masculine discrepancy stress and intimate partner violence. AB - Research on gender roles suggests that men who strongly adhere to traditional masculine gender norms are at increased risk for the perpetration of violent and abusive acts toward their female intimate partners. Yet, gender norms alone fail to provide a comprehensive explanation of the multifaceted construct of intimate partner violence (IPV) and there is theoretical reason to suspect that men who fail to conform to masculine roles may equally be at risk for IPV. In the present study, we assessed effect of masculine discrepancy stress, a form of distress arising from perceived failure to conform to socially-prescribed masculine gender role norms, on IPV. Six-hundred men completed online surveys assessing their experience of discrepancy stress, masculine gender role norms, and history of IPV. Results indicated that masculine discrepancy stress significantly predicted men's historical perpetration of IPV independent of other masculinity related variables. Findings are discussed in terms of potential distress engendered by masculine socialization as well as putative implications of gender role discrepancy stress for understanding and intervening in partner violence perpetrated by men. PMID- 29593369 TI - Do Transnational Child-Raising Arrangements Affect Job Outcomes of Migrant Parents? Comparing Angolan Parents in Transnational and NonTransnational Families in the Netherlands. AB - Transnational family literature has established that parent-child separations affect negatively on the emotional well-being of migrant parents. Less attention has been paid to other effects separation can have on these parents' lives. Building on insights from transnational family studies and organizational psychology, this article explores the potential link between transnational family life and job outcomes. In particular, two potential negative outcomes are analyzed-job instability and job absenteeism-by comparing Angolan parents whose children live in Angola with Angolans who live with all their children in the Netherlands. Based on mechanisms identified by organizational psychology literature, mediation analysis is conducted. Results indicate that transnational family life increases the times migrant parents change jobs, which is partly mediated by low levels of happiness. Further analyses indicate that especially transnational parents who have limited contact with their children change jobs more often. No significant differences are found with regard to job absenteeism. PMID- 29593370 TI - Conflict Structures in Family Networks of Older Adults and Their Relationship With Health-Related Quality of Life. AB - This study explores the interrelationships between health-related quality of life and conflict structures in family networks of older adults. Data were derived from a sample of 2,858 elders (aged 65 years and older) from the Vivre/Leben/Vivere study, a large survey addressing family life and health conditions of older people in Switzerland. Conflict density in family networks and the betweenness centrality of respondents in family conflict are significantly associated with health-related quality of life measures. Furthermore, the results demonstrate that conflict-health associations are mediated by the level of perceived individual stress where psychological health is concerned. Family conflict structures depend to a large extent on family composition and age. This study stresses the importance of older adults actively shaping the composition of their family contexts in ways that promote both conflict and stress avoidance. PMID- 29593371 TI - The Ties That Bind: Materiality, Identity, and the Life Course in the "Things" Families Keep. AB - Using an interdisciplinary research methodology across three archaeological and historical case studies, this article explores "family archives." Four themes illustrate how objects held in family archives, curation practices, and intergenerational narratives reinforce a family's sense of itself: people-object interactions, gender, socialization and identity formation, and the "life course." These themes provide a framework for professional archivists to assist communities and individuals working with their own family archives. We argue that the family archive, broadly defined, encourages a more egalitarian approach to history. We suggest a multiperiod analysis draws attention to historical forms of knowledge and meaning-making practices over time. PMID- 29593373 TI - Exploring the use of situation awareness in behaviors and practices of health and safety leaders. AB - An understanding of how health and safety management systems (HSMS) reduce worksite injuries, illnesses and fatalities may be gained in studying the behaviors of health and safety leaders. These leaders bear the accountability for identifying, understanding and managing the risks of a mining operation. More importantly, they have to transfer this knowledge of perception, recognition and response to risks in the mining environment to their workers. The leaders' efforts to build and maintain a mining operation's workforce that consistently executes safe work practices may be captured through more than just lagging indicators of health and safety performance. This exploratory study interviewed six leaders in occupations such as site-level safety supervisors, mine superintendents and/or general managers at surface and underground stone, sand and gravel and metal/nonmetal mine sites throughout the United States, with employee populations ranging from 40 to 175. In exploring leaders' perspectives on how they systematically manage health and safety, examples such as approaches to task training, handling near-miss incidents, identifying future leaders and providing workers with feedback offer insights into how leaders translate their knowledge and management of site-level risks to others. PMID- 29593372 TI - Empirical Examinations of Modifications and Adaptations to Evidence-Based Psychotherapies: Methodologies, Impact, and Future Directions. AB - This review describes methods used to examine the modifications and adaptations to evidence-based psychological treatments (EBPTs), assesses what is known about the impact of modifications and adaptations to EBPTs, and makes recommendations for future research and clinical care. One hundred eight primary studies and three meta-analyses were identified. All studies examined planned adaptations, and many simultaneously investigated multiple types of adaptations. With the exception of studies on adding or removing specific EBPT elements, few studies compared adapted EBPTs to the original protocols. There was little evidence that adaptations in the studies were detrimental, but there was also limited consistent evidence that adapted protocols outperformed the original protocols, with the exception of adding components to EBPTs. Implications for EBPT delivery and future research are discussed. PMID- 29593374 TI - Examining the Prevalence and Predictors of Injury from Adolescent Dating Violence. AB - Medical needs of youth who experience dating violence are not well understood because of limited past research examining the prevalence and predictors of injuries and medical help seeking. To address these gaps, the current study described the prevalence and predictors of injuries from dating violence from grades 8 through 12 in a large sample of youth. Results indicate that one third to one half of youth who experienced any physical and/or sexual dating violence also sustained an injury. Prevalence of injury was highest in the 8th grade and was significantly higher for females than for males across grades 8 through 11. Youth who experienced greater amounts of violent victimization in their relationships (physical, sexual, and psychological) were at highest risk for injury. Results also suggest that victims at highest risk for injury are girls, white youth, those experiencing multiple types of violence, and those who also engage in perpetration. Given the high prevalence of injury among youth who report dating violence, healthcare professionals may be in a unique position to screen and counsel youth about dating violence. Because the highest prevalence of injury occurred before high school, prevention programs should start early and selected prevention may be used for youth at highest risk for injury. PMID- 29593375 TI - Chitosan Membrane Embedded With ZnO/CuO Nanocomposites for the Photodegradation of Fast Green Dye Under Artificial and Solar Irradiation. AB - Fast Green (FCF) dye is commonly used in both cytology and histology applications. Previous studies have found that it can cause mutagenic and tumorigenic effects in experimental human and animal populations. It can also be a source of skin, eye, respiratory, and digestive irritation. The purpose of this study was to examine the use of thin film membranes to degrade FCF. A thin film membrane of chitosan (CS) was fabricated and subsequently filled with zinc oxide nanoparticles (ZnO) or ZnO/CuO-heterostructured nanocomposites. The CS membrane was used as a matrix, and the nanomaterials were used as photocatalysts. The prepared membranes were characterised by four analytical techniques: atomic force microscopy, scanning electron microscopy, X-ray diffraction, and energy dispersive X-ray analyses. The photocatalytic activity of the fabricated membranes was evaluated by performing experiments in which aqueous solutions of FCF dye that contained the fabricated membrane were irradiated with solar light or UV light. The photodegradation percentage was spectrophotometrically determined by monitoring the maximum wavelengths (lambdamax) of FCF at 623 nm for different irradiation times. The decolourisation percentages of the dye under solar light were 57.90% and 60.23% using the CS-ZnO and CS-ZnO/CuO membranes, respectively. When UV light irradiation was employed as the source of irradiation, the photodegradation percentages of FCF were 71.45% and 91.21% using the CS-ZnO and CS-ZnO/CuO membranes, respectively. These results indicated that the best photocatalytic system for the degradation of FCF dye was CS-ZnO/CuO membrane in combination with UV light irradiation. The study also found that it was easy to separate the prepared membranes after the reaction without the need for a centrifuge or magnet. The results demonstrate the potential for CS-ZnO and CS-ZnO/CuO membranes for use as effective sorbents during the process of photodegradation of harmful dyes within waste water recycling practices. PMID- 29593376 TI - Clinical and virological analysis of epidemic keratoconjunctivitis caused by adenovirus type 54 in a regional ophthalmic clinic in Kyushu, Japan. AB - Background: Human adenovirus type 54 (HAdV-54) is a novel type of adenovirus that belongs to species D and has thus far been detected only in Japan in patients with epidemic keratoconjunctivitis (EKC). There was a large nationwide outbreak of HAdV-54 EKC from 2015 to 2016 in Japan. The clinical characteristics of an outbreak of HAdV-54 conjunctivitis treated in a regional ophthalmic clinic in Fukuoka, Japan, in 2016 were analyzed. Patients and methods: A consecutive series of 55 cases diagnosed clinically as EKC confirmed by HAdV-54 detection from conjunctival scrapings by polymerase chain reaction (PCR) method between 17 June 2016 and 29 August 2016 were enrolled. Viral DNA copies were counted by real-time PCR method. The clinical findings were recorded at the first visit to the clinic and evaluated. Results: In the analysis of the relationship between mean clinical score groups and several factors, such as days after onset, sex, HAdV DNA number on a logarithmic scale, and age, most factors did not show a significant difference in clinical score between groups. However, mean clinical score of cases aged <23 years was significantly higher than that of cases aged >=23 years (P<0.01). The correlation coefficient between DNA copies on a logarithmic scale and clinical score was 0.280, and a significant correlation was observed (P<0.05). Multiple subepithelial corneal infiltrates (MSI) were observed in 24 out of 31 cases (77%). Conclusion: These results suggested that the clinical features in the early phase of HAdV-54 keratoconjunctivitis were milder but the rate of MSI observed in the late phase was higher than those in previous epidemics of several HAdV types. The significant difference in clinical severity between age groups might be a virological characteristic of HAdV-54. PMID- 29593378 TI - Comparative study of induced changes in effective lens position and refraction after Nd:YAG laser capsulotomy according to intraocular lens design. AB - Purpose: To evaluate and compare the changes in refraction and effective intraocular lens (IOL) position between a plate-haptic IOL and a c-loop single piece IOL after neodymium-doped yttrium aluminium garnet (YAG) laser posterior capsulotomy. Methods: In a prospective study, anterior chamber depth and subjective refraction were measured in 110 pseudophakic eyes from 110 patients, before and 1 month after YAG laser capsulotomy. Patients were divided into 2 groups according to the IOL design: group 1 (plate-haptic acrylic hydrophilic AT LISA tri 839MP(r)) and group 2 (c-loop acrylic hydrophobic single-piece AcrySof(r) SA60AT). Lens position was obtained through optical coherence biometry (Biograph WaveLight OB820(r)). Results: YAG laser capsulotomy was performed 37.8+/-9.8 months after surgery in group 1 and 40.6+/-8.6 months in group 2 (p=0.125). Significant changes were found in the lens effective position after treatment in the 2 groups. The YAG posterior capsulotomy led to a change of anterior chamber depth in group 1 from 4.03+/-0.32 mm to 3.86+/-0.34 mm (p=0.02) and in group 2 from 4.03+/-0.37 mm to 4.14+/-0.45 mm (p=0.025). After YAG laser posterior capsulotomy, no significant changes were observed in mean spherical equivalent, sphere or cylinder for both groups (p>0.05). Conclusion: YAG laser posterior capsulotomy can induce a significant change in the IOL position according to the IOL type; however, the refractive change after treatment is clinically insignificant. PMID- 29593377 TI - Management of chronic ocular sarcoidosis: challenges and solutions. AB - Background: Sarcoidosis constitutes one of the leading causes of ocular inflammation. Chronic ocular sarcoidosis can affect any segment of the eye and its adnexa, producing a wide range of clinical manifestations and severity. If left untreated, permanent visual impairment or even blindness may ensue. Treatment approaches vary from topical therapy to systemic agents that induce immunosuppression to different levels according to disease severity. Objective: To review the published literature on the management options for chronic ocular sarcoidosis and provide a comprehensive list of available treatment strategies, including the newer biologics. Summary: Ocular disease remains a challenging aspect of sarcoidosis and may even be the presenting sign of the disease. Prompt and effective therapy may reverse visual damage and prevent permanent loss of vision. Because of the complexity of the disease, a multidisciplinary approach is often required, with a view to addressing both the ocular and other systemic manifestations of sarcoidosis. Recent data suggest that achieving overall optimal systemic control is of paramount importance in controlling eye inflammation as well. Cytotoxic immunosuppressive agents for refractory chronic ocular disease, as well as biologic anti-TNFalpha therapies, have advanced the management of chronic disease and should be considered corticosteroid-sparing strategies before the onset of significant steroid-induced morbidity. PMID- 29593379 TI - The clinical effectiveness of tafluprost on Japanese normal-tension glaucoma patients. AB - Purpose: This study evaluates the effect of tafluprost on visual field progression in normal-tension glaucoma (NTG) in a Japanese population under daily clinical practice settings. Patients and methods: This is a post-marketing, multicenter, non-interventional, observational study. Patients with NTG who initiated tafluprost treatment were registered and prospectively observed for 2-3 years to investigate its effectiveness on visual field progression and intraocular pressure (IOP) and safety in Japan. Visual field progression was evaluated using mean deviation (MD) slopes in a visual field analysis set that comprised patients with reliable Humphrey visual fields taken at 5 or more time points throughout the 2-3 years. Results: Of the 1,454 patients registered from 160 medical institutions, 1,353 were set for safety analysis and 416 were set for visual field analysis. Due to insufficient effectiveness or safety reasons 194 patients discontinued tafluprost, and 388 patients discontinued tafluprost due to being lost to follow-up or another reason. The MD slopes were -0.09+/-0.85 dB/year in the entire visual field analysis set, -0.02+/-0.80 dB/year in naive monotherapy patients, -0.07+/-0.68 dB/year in switching monotherapy patients, and -0.32+/-1.04 dB/year in concomitant therapy patients. In naive monotherapy, a significant difference in MD slopes was observed between patients with an IOP reduction of 10% or higher (0.11+/-0.73 dB/year) vs patients with an IOP reduction of <10% (-0.22+/-0.87 dB/year). Significant differences were also observed in the subset analyses when the patients were divided by both MD and IOP at baseline, and presence of vitreoretinal concomitant disease. The adverse reactions were observed in 9.53% patients without any serious adverse reactions. Conclusion: An at least 10% IOP reduction with tafluprost monotherapy in 56.7% of the treatment-naive NTG eyes was sufficient to significantly reduce the MD rate of progression. PMID- 29593380 TI - Bioequivalence of a biosimilar enoxaparin sodium to Clexane(r) after single 100 mg subcutaneous dose: results of a randomized, double-blind, crossover study in healthy volunteers. AB - Purpose: To demonstrate the pharmacokinetic/pharmacodynamic (PK/PD) equivalence of a biosimilar enoxaparin to the reference drug, and to assess its safety and tolerability in healthy volunteers. Patients and methods: A randomized, double blind, crossover, 2-sequence, single-dose study was conducted in healthy volunteers of both sexes. Participants were sequentially and randomly administered single subcutaneous injections of enoxaparin 100 mg manufactured by Rovi (test; Madrid, Spain) and Clexane(r) (enoxaparin 100 mg manufactured by Sanofi, reference) separated by a 1-week washout period. The primary PK/PD variables were maximum activity (Amax) and area under the effect curve from time 0 to the last measured activity (T) (AUEC0-T) and AUEC from time 0 to infinity (AUEC0-inf) of anti-FXa activity, and Amax and AUEC0-T of anti-FIIa activity. Secondary variables were Amax and AUEC0-T, AUEC0-inf of tissue factor pathway inhibitor, and the ratio of AUEC0-T anti-FXa to anti-FIIa activity. Biosimilarity would be shown when the 95% CI of the ratio of geometric least squares means (95% CI RGLSMs) of primary PK/PD parameters fell within the standard range of bioequivalence, ie, 80%-125%. Results: The study sample consisted of 46 volunteers (33 males) aged 18-44 years and with body mass index ranging from 19.0 to 31.1 kg/m2. Three subjects did not complete the study. The curves of anti-FXa, anti-FIIa and tissue factor pathway inhibitor activities corresponding to administration of the test and reference products were comparable. The 95% CI RGLSMs of Amax, AUEC0-T and AUEC0-inf for anti-FXa activity were 94.6%-105.9%, 99.8%-108.0% and 100.0%-108.6% respectively; Amax and AUEC0-T for anti-FIIa activity were 94.7%-112.6% and 90.9%-117.9% respectively. In addition, the 95% CI RGLSMs of all secondary variables fell within the range 80%-125%. The incidence and types of adverse events after administration of the test and reference drugs were similar. Conclusion: The results conclusively showed that the enoxaparin manufactured by Rovi is equivalent to the reference enoxaparin in all primary and secondary PK/PD parameters, as required by the European Medicines Agency to grant marketing authorization to a biosimilar low molecular-weight heparin. PMID- 29593381 TI - The hydroxypropyl-beta-cyclodextrin complexation of toltrazuril for enhancing bioavailability. AB - Introduction: Toltrazuril (Tol) is used to prevent and combat coccidiosis. However, its low aqueous solubility and poor oral bioavailability limit clinical application. Methods: To overcome the shortcomings, toltrazuril-hydroxypropyl beta-cyclodextrin inclusion complex (Tol-HP-beta-CD) was prepared and characterized. The comparative plasma disposition kinetics of Tol was analyzed after a single orally administered dose of 10 mg/kg Tol or Tol-HP-beta-CD in rabbits. Solution-stirring method was selected to prepare the inclusion complex. Complex formation was characterized by thin-layer chromatography, Fourier transform infrared spectrophotometry, and 1H nuclear magnetic resonance spectroscopy. In plasma profile, plasma samples were collected between 1 and 10 days following administration. Plasma Tol concentrations were determined by high performance liquid chromatography. Results: In rabbit plasma, the time to peak concentration (Tmax) of Tol-HP-beta-CD was shorter than that of Tol (12 h vs 24 h). Cmax (19.92+/-1.02 MUg/mL) and area under the concentration-time curve (AUC0 infinity, 1,176.86+/-70.26 mg/L h) of the Tol-HP-beta-CD group significantly increased (p,0.01) than those of the Tol group (Cmax, 8.02+/-1.04 MUg/mL; AUC0 infinity, 514.03+/-66.65 mg/L h). Conclusion: It can be concluded that the Tol-HP beta-CD increased the aqueous solubility and enhanced the oral bioavailability in rabbits. Complexation with HP-beta-CD is a feasible way to prepare a rapidly absorbed and more bioavailable Tol oral product. PMID- 29593383 TI - "I did not want to take that medicine": African-Americans' reasons for diabetes medication nonadherence and perceived solutions for enhancing adherence. AB - Background: Diabetes is disproportionally burdensome among African-Americans (AAs) and medication adherence is important for optimal outcomes. Limited studies have qualitatively examined reasons for nonadherence among AAs with type 2 diabetes, though AAs are less adherent to prescribed medications compared to whites. This study explored the reasons for medication nonadherence and adherence among AAs with type 2 diabetes and examined AAs' perceived solutions for enhancing adherence. Methods: Forty AAs, age 45-60 years with type 2 diabetes for at least 1 year prior, taking at least one prescribed diabetes medication, participated in six semistructured 90-minute focus groups. Using a phenomenology qualitative approach, reasons for nonadherence and adherence, as well as participants' perceived solutions for increasing adherence were explored. Qualitative content analysis was conducted. Results: AAs' reasons for intentional nonadherence were associated with 1) their perception of medicines including concerns about medication side effects, as well as fear and frustration associated with taking medicines; 2) their perception of illness (disbelief of diabetes diagnosis); and 3) access to medicines and information resources. Participants reported taking their medicines because they valued being alive to perform their social and family roles, and their belief in the doctor's recommendation and medication helpfulness. Participants provided solutions for enhancing adherence by focusing on the roles of health care providers, patients, and the church. AAs wanted provider counseling on the necessity of taking medicines and the consequences of not taking them, indicating the need for the AA community to support and teach self-advocacy in diabetes self-management, and the church to act as an advocate in ensuring medication use. Conclusion: Intentional reasons of AAs with type 2 diabetes for not taking their medicines were related to their perception of medicines and illness. Solutions for enhancing diabetes medication adherence among AAs should focus on the roles of providers, patients, and the church. PMID- 29593382 TI - Tendinopathy: injury, repair, and current exploration. AB - Both acute and chronic tendinopathy result in high morbidity, requiring management that is often lengthy and expensive. However, limited and conflicting scientific evidence surrounding current management options has presented a challenge when trying to identify the best treatment for tendinopathy. As a result of shortcomings of current treatments, response to available therapies is often poor, resulting in frustration in both patients and physicians. Due to a lack of understanding of basic tendon-cell biology, further scientific investigation is needed in the field for the development of biological solutions. Optimization of new delivery systems and therapies that spatially and temporally mimic normal tendon physiology hold promise for clinical application. This review focuses on the clinical importance of tendinopathy, the structure of healthy tendons, tendon injury, and healing, and a discussion of current approaches for treatment that highlight the need for the development of new nonsurgical interventions. PMID- 29593384 TI - Cross-cultural adaptation and validation of the Arabic version of the Physical Activity Scale for the Elderly among community-dwelling older adults in Saudi Arabia. AB - Purpose: Older adults are the fastest growing population group worldwide. Regular physical activity (PA) is reported to reduce the risk of health conditions and improve personal well-being. Few validated instruments can be used to measure the PA levels among older adults in Saudi Arabia. The Physical Activity Scale for the Elderly (PASE) is used worldwide for evaluating the PA levels of the elderly in epidemiological studies. However, this scale has not been translated into Arabic. This study aimed to cross-culturally adapt the PASE into Arabic language and evaluate its reliability and validity among community-dwelling older adults in Saudi Arabia. Patients and methods: This study was a cross-sectional one following Beaton guidelines to translate and perform cultural adaptation, as well as test the reliability and validity of the PASE Arabic version (PASE-A). Elderly (N=74) people from both genders, who lived in a community dwelling in Riyadh city, were selected from several primary health care centers. The study used Cronbach's alpha coefficient to assess the internal consistency reliability, while intraclass correlation coefficient (ICC2,1) was used for test-retest reliability and the Spearman's rank correlation coefficient (r) was used to evaluate the correlation among PASE-A and grip strength, Timed Up and Go test, body mass index, and fat percentage. Results: Out of 74 older adults, 59 (79.7%) completed the PASE-A questionnaire twice. The internal consistency of the PASE-A components was good (Cronbach's alpha 0.70-0.75), and the reliability of the components was excellent (ICC2,1 0.90-0.98). A higher PASE-A score was associated with higher grip strength (r=0.28, p=0.05) and with shorter Timed Up and Go test times (r=-0.45, p=0.01). Conclusion: The PASE-A version was easy, understandable, and relevant for Saudi older adults' culture. This scale was a reliable and valid tool for evaluating and assessing the PA level among community-dwelling older adults in Saudi Arabia. PMID- 29593385 TI - Biological age as a health index for mortality and major age-related disease incidence in Koreans: National Health Insurance Service - Health screening 11 year follow-up study. AB - Purpose: A comprehensive health index is needed to measure an individual's overall health and aging status and predict the risk of death and age-related disease incidence, and evaluate the effect of a health management program. The purpose of this study is to demonstrate the validity of estimated biological age (BA) in relation to all-cause mortality and age-related disease incidence based on National Sample Cohort database. Patients and methods: This study was based on National Sample Cohort database of the National Health Insurance Service - Eligibility database and the National Health Insurance Service - Medical and Health Examination database of the year 2002 through 2013. BA model was developed based on the National Health Insurance Service - National Sample Cohort (NHIS - NSC) database and Cox proportional hazard analysis was done for mortality and major age-related disease incidence. Results: For every 1 year increase of the calculated BA and chronological age difference, the hazard ratio for mortality significantly increased by 1.6% (1.5% in men and 2.0% in women) and also for hypertension, diabetes mellitus, heart disease, stroke, and cancer incidence by 2.5%, 4.2%, 1.3%, 1.6%, and 0.4%, respectively (p<0.001). Conclusion: Estimated BA by the developed BA model based on NHIS - NSC database is expected to be used not only as an index for assessing health and aging status and predicting mortality and major age-related disease incidence, but can also be applied to various health care fields. PMID- 29593387 TI - Nanoantibiotics: strategic assets in the fight against drug-resistant superbugs. AB - Antimicrobial characteristics of metals reveal that Ag despite its economic constraints remains the most popular antibiotic agent. Antimicrobial characteristics of copper nanoparticles (CNPs) are not well understood. To our knowledge, no systematic comparative study on microbial properties of silver nanoparticles (SNPs) and CNPs exists. In this article, a comparative study on microbial properties of engineered metal nanoantibiotics against clinically important strains has been attempted. Our results indicate that biocidal activities of CNPs are better than SNPs. Minimum inhibitory concentration (MIC) values of CNPs are 10 times lower than the corresponding MICs of SNPs. These improved biocidal activities of CNPs would make it affordable and potent nontraditional antibiotics against which microbes are least susceptible to develop any drug resistance. PMID- 29593386 TI - Lack of association between airflow limitation and recurrence of venous thromboembolism among cancer patients with pulmonary embolism. AB - Background: COPD is a well-known risk factor for venous thromboembolism (VTE) development. However, recent data showed that it was not associated with VTE recurrence risk, which excluded cancer patients. This study investigated the association of airflow limitation and VTE recurrence in cancer patients with pulmonary embolism (PE). Methods: This is a retrospective cohort study of cancer patients with newly diagnosed PE at a university hospital. PE was confirmed using contrast-enhanced computed tomography scan. Airflow limitation was defined as pre bronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) <0.7 within 2 years of PE diagnosis. VTE recurrence was defined as a composite of recurrence as PE or deep vein thrombosis or both. Results: Among 401 cancer patients with newly diagnosed PE, spirometry-based airflow limitation was observed in 126 (31.4%) patients. Half of the patients had lung cancer, which was more common in the group with airflow limitation (65.1% vs 42.9%, p < 0.001). Symptomatic PE was present in less than half (45.4%) of the cases, and 62.6% of patients were treated for PE. During the median follow-up period of 9.7 months, VTE recurred in 49 (12.2%) patients. Compared with patients without airflow limitation, those with airflow limitation did not have an increased risk of VTE recurrence in univariate or multivariate analyses (adjusted hazard ratio, 1.29 [95% CI 0.68, 2.45]). Conclusion: The presence of airflow limitation did not increase the risk of VTE recurrence in cancer patients with PE. Prospective studies are needed to validate this finding. PMID- 29593388 TI - Iron oxide-doped niosomes as drug carriers for magnetically targeted drug delivery. AB - Magnetism has wide applications in various fields, such as diagnostics, drug targeting, molecular biology, cell isolation, cell purification, hyperthermia, and radioimmunoassay. In this study, we synthesized niosomes doped with iron oxide nanoparticles and a fluorophore for potential applications in magnetically targeted drug delivery. Release kinetics of the fluorophore and cytotoxicity were assessed. The results demonstrate that niosomes doped with iron oxide nanoparticles can serve as proficient and effective drug carriers in magnetically targeted drug delivery. PMID- 29593389 TI - Liposome encapsulation of doxorubicin and celecoxib in combination inhibits progression of human skin cancer cells. AB - Therapeutic agents aimed at inhibiting a single molecular target have not been successful in cancer therapy, but rather they impart resistance. However, multi target inhibitors have shown promising results in circumventing the development of resistance and inducing apoptosis in cancer cells/tissues. In this study, we encapsulated doxorubicin and celecoxib in a single liposome at a ratio of 1:10. These dual drug-encapsulated liposomes showed excellent anticancer activity compared to individually encapsulated liposomes. The expression of key proteins such as AKT and COX-2 was suppressed, which suggests that doxorubicin and celecoxib synergistically inhibit multiple key signaling pathways. PMID- 29593390 TI - Fluorescent gold nanoclusters for efficient cancer cell targeting. AB - Well-known surface properties of gold nanoparticles (AuNPs) offer easy surface modification with desired biomolecule, thus enabling them to be used for targeting and imaging of cancer cells/tissues. However, targeting and imaging capability come through after synthesis coating of AuNPs' surface with targeting or imaging molecules. Attempts have been made to conjugate both imaging and targeting molecules over the AuNPs, but have seen limited success. Hence, exploiting the fluorescence properties of gold nanoclusters (AuNCs), we have synthesized glucose-coated AuNCs for exhibiting both the imaging and targeting properties. These clusters have shown rapid and selective uptake in cancerous (A549) cells when compared with bovine serum albumin-coated AuNCs. PMID- 29593391 TI - Removal of pesticide toxicity by cysteine-capped Ag nanoparticles and study of their adsorption kinetics. AB - A new method has been developed for one-step synthesis of cysteine-capped Ag nanoparticles. The particles have been characterized by several techniques, including ultraviolet-visible spectroscopy, infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The interaction of these nanoparticles has been seen with two pesticides, namely, chlorpyrifos and malathion, which are major water pollutants. PMID- 29593392 TI - Oral bioavailability enhancement of agomelatine by loading into nanostructured lipid carriers: Peyer's patch targeting approach. AB - Agomelatine (AGM) is a new antidepressant drug with a novel mechanism of action and fewer side effects compared with older antidepressants. AGM is a melatonin receptor (MT1 and MT2) agonist and 5-hydroxytryptamine receptor (5-HT2C) antagonist. In the present study, the enhancement of the oral bioavailability of AGM was formulated and loaded into nanostructured lipid carriers (NLCs), using ultrasonication method. In vitro and ex vivo drug release was performed using a dialysis bag and rat duodenum, respectively. Our pharmacodynamic study showed that AGM-NLCs are more efficacious than a pure drug and marketed product, and confocal microscopy revealed lymphatic uptake of AGM-NLCs. The present study concluded that the NLCs enhanced the oral bioavailability of AGM (6.5-fold) by avoiding its first-pass metabolism by way of lymphatic uptake. PMID- 29593393 TI - Cellular internalization and antioxidant activity of cerium oxide nanoparticles in human monocytic leukemia cells. AB - Overproduction of free radicals contributes to oxidative stress and inflammation leading to various disease conditions. Cerium oxide nanoparticles (nanoceria) have been shown to scavenge free radicals and have the potential for being used as a therapeutic agent in disease conditions. Therefore, in the present study, human monocytic leukemia cells (THP-1) were used as a model to evaluate the uptake and free radical scavenging activity of nanoceria. Our data showed a significant (P<0.05) increase in the internalization of nanoceria in a concentration-dependent (10-100 ug/mL) manner in THP-1 cells. Although no cytotoxicity was observed at these concentrations, nanoceria significantly (P<0.05) reduced the amount of reactive oxygen species. This was evident by a significant (P<0.05) decrease in the 2,7-dichlorofluorescein diacetate fluorescence observed in flow cytometry and fluorescence microscopy. The present study shows that nanoceria have therapeutic potential in diseases such as cancer. PMID- 29593394 TI - Titanium dioxide nanoparticle-protein interaction explained by docking approach. AB - Titanium dioxide has been proven for toxicity by in vitro and in vivo approaches, however, further studies are needed in nano-toxicological research using in silico analysis. In this study, Autodock 4.0.5 was used in an attempt to evaluate the interaction of titanium dioxide with proteins. Different cellular proteins were sorted to study the interaction, binding sites, and active sites as a pocket. These pockets have been determined using CastP - an online server. The analysis for the docked structures was performed with regard to the most efficient binding with amino acids. This study is the first of its kind to report on the in silico docking interaction of titanium dioxide nanoparticles without any surface modification. The higher negative binding energy shows strong binding of titanium dioxide with proteins. A strong interaction with different cellular proteins was observed, and more specifically, titanium dioxide nanoparticles showed frequent interaction with proline, lysine, as well as leusine. PMID- 29593395 TI - Liposomal formulation of vitamin A for the potential treatment of osteoporosis. AB - Vitamin A targeting to bones is a suitable treatment for osteoporosis. In this study, we have developed vitamin A-encapsulated liposomes that can be useful to deliver vitamin A to the bones in a selective manner. This liposomal formulation of vitamin A has been found to be stable for >6 months as no significant change in size and charge occurred. Vitamin A liposomes-induced cell proliferation in SaOS-2 (human osteosarcoma cell line) and release kinetics study concluded that the liposomal formulation of vitamin A gives a controlled release of vitamin A in comparison to the free vitamin. The MTT assay showed the proliferation of SaOS-2 cells after their treatment with vitamin A liposomes. PMID- 29593396 TI - Patterning artificial lipid bilayer on nanostructured surfaces. AB - Artificial lipid bilayer on solid substrate plays an important role as an interface between nanotechnology and biology. In this study, grid structures were patterned on Au-Nb-glass substrate and artificial bilayer was prepared on these structures. The fluidity was checked using fluorescence recovery after photobleaching (FRAP), and neuronal adhesion was monitored on such structure using EphrinA5-tethered lipid bilayer. EphrinA5 is a ligand that binds to the Eph receptors of rat cortical neurons and influences cellular adhesion. Our result elucidated that influence of these nanopatterned protein-tethered lipid bilayer on cellular guidance and signaling can address many underlying mechanisms of cellular functioning and help us to understand and differentiate the signaling procedure in cancer and neurodegenerative diseases. PMID- 29593397 TI - In vitro analysis of PARP inhibitor nanoformulations. AB - PARP-l is a DNA repair protein that plays a role in a number of repair pathways and also helps in transcriptional regulation; thus PARP inhibitors (PARPi), such as olaparib and BMN-673, act by inhibiting DNA damage repair. This leads to an accumulation of deleterious mutations leading to genetic instability as a result of a number of cell replications. Currently, olaparib is only available in an oral form and has poor bioavailability, consequently leading to poor accumulation in the tumor due to first-pass metabolism. Therefore, in the present study, an injectable nanoparticle formulation of olaparib was created that offers a delivery route in which the drug would be fully bioavailable in the vasculature, suggesting greater tumor accumulation. Our results illustrated that injectable nanoformulations of olaparib and BMN-673, a next generation PARPi, could be developed, and an efficacy test indicated that BMN-673 is a much more potent PARPi than olaparib. The success of these molecular inhibitors as a monotherapy in inhibiting colony formation suggests enhanced efficacy of these treatments in combination with other therapies, even in tumors which have developed resistance. PMID- 29593398 TI - Synthesis and in vitro studies of PLGA-DTX nanoconjugate as potential drug delivery vehicle for oral cancer. AB - Advances in nanotechnology have led to the design of multifunctional nanoparticles capable of cellular imaging, targeted drug delivery, and diagnostics for early cancer detection. We synthesized poly(lactic-co-glycolic acid) nanoparticles encapsulating a model radiosensitizing drug docetaxel accomplishing localized in situ delivery of the sensitizer to the tumor site. The synthesized nanoparticles have been characterized for their physicochemical properties. The in vitro cytotoxicity of drug-loaded nanoparticles has been studied on human tongue carcinoma cell line SCC-9 (ATCC-CRL-1629). PMID- 29593399 TI - Preferential binding of fullerene and fullerenol with the N-terminal and middle regions of amyloid beta peptide: an in silico investigation. AB - Amyloid beta (Abeta) deposits are implicated in the pathogenesis of debilitating neurodegenerative disorders such as Alzheimer's disease. In the present study, the interactions of carbon-based nanoparticles (NPs) such as fullerene and fullerenol having different surface chemistry with Abeta were investigated using molecular dynamics simulations and docking studies. A detailed analysis of docking results showed that in 68% of the Abeta conformations, fullerene and fullerenol showed interactions with the N-terminal region of the peptide. However, the high-affinity binding site (E=-48.31 kJ/mol) of fullerene resides in the hydrophobic middle region of the peptide, whereas fullerenol interacts favorably with the charged N-terminal region with a binding energy of -50.42 kJ/mol. The above differences in binding could be attributed to the surface chemistry of fullerene and fullerenol. Moreover, the N-terminal and middle regions of Abeta play an important role in Abeta aggregation. Therefore, the binding of fullerene and fullerenol could inhibit amyloid aggregation. This information will be helpful in designing NPs for targeting amyloid-related disorders. PMID- 29593400 TI - Curcumin Ag nanoconjugates for improved therapeutic effects in cancer. AB - Curcumin has a broad spectrum of pharmacological activities, one of them is anticancer activity that is mediated through multiple mechanisms. The major disadvantage associated with the use of curcumin is its low bioavailability due to its poor aqueous solubility. Nanoformulations of curcumin provide an effective solution for this problem. In this study, we have synthesized curcumin Ag nanoconjugates and evaluated their anticancer potential. PMID- 29593401 TI - Synthesis of biocompatible iron oxide nanoparticles as a drug delivery vehicle. AB - Over the last decade, there has been growing interest in developing novel nanoparticles (NPs) for biomedical applications. A safe-by-design approach was used in this study to synthesize biocompatible iron oxide NPs. The size of the particles obtained was ~100 nm. Although these NPs were significantly (P<0.05) internalized in MCF-7 (human breast adenocarcinoma cell line) cells, no adverse effect was observed in the cells as assessed by cytotoxicity assays (neutral red uptake and 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) and cell cycle analysis. Our data demonstrate the potential of iron oxide NPs as a biocompatible carrier for targeted drug delivery. PMID- 29593402 TI - Cholic acid-modified polyethylenimine: in vitro and in vivo studies. AB - Low-molecular-weight polyethylenimine has lower cytotoxicity than high molecular weight polyethylenimine, but it is not an efficient transfection agent because of limitations of DNA delivery into the cytoplasm. Therefore, in the present study, the hydrophobic modification of low-molecular-weight polyethylenimine (PEI 2 kDa [PEI2]) by cholic acid (ChA) was performed to form PEI2-ChA, and in vitro and in vivo studies were performed. Results indicate that the nanoplexes of PEI2-ChA with gWIZ-GFP have greater transfection efficiency (27%) in NT8e cell lines as evaluated by flow cytometry and also observed by fluorescence imaging. The present study concluded that the transferrin-containing nanoplexes of PEI2-ChA conjugates with plasmid p53 warrant clinical trials in humans after exhaustive animal studies for use as a novel gene delivery system. PMID- 29593403 TI - Modification of porous polyethylene scaffolds for cell attachment and proliferation. AB - Synthetic polymers are widely researched for their use in tissue engineering. Control in size, surface area, pore size, and elasticity are the biggest advantages of using a man-made polymer. However, often the polymers are hydrophobic (do not encourage cell attachment); hence, it is hugely challenging to integrate them with the normal tissues. Herein, we have tried to overcome this disadvantage of polymers by coating them with citrate-stabilized gold nanoparticles and arginine. High-density polyethylene, upon multiple treatments, shows low water contact angle, which encourages cell attachment and proliferation in comparison to the untreated polymers. PMID- 29593404 TI - In vitro studies on oxidative stress-independent, Ag nanoparticles-induced cell toxicity of Candida albicans, an opportunistic pathogen. AB - Silver nanoparticles (AgNps) have attracted maximal attention among all metal nanoparticles, and the study of their biological properties has gained impetus for further medical adoption. This study evaluated the cellular and molecular mechanisms associated with the action of AgNps against an opportunistic pathogen, Candida albicans. Spherical, stable AgNp (average size 21.6 nm) prepared by a chemical reduction method showed minimum inhibitory concentration (required to inhibit the growth of 90% of organisms) at 40 MUg/mL. AgNps have been reported to induce oxidative stress-mediated programmed cell death through the accumulation of intracellular reactive oxygen species (ROS). However, this study demonstrated that intracellular levels of AgNp-induced ROS could be reversed by using antioxidant ascorbic acid, but the sensitivity of AgNp-treated Candida cells could not be completely reversed. Moreover, in addition to the generation of ROS, the AgNps were found to affect other cellular targets resulting in altered membrane fluidity, membrane microenvironment, ergosterol content, cellular morphology, and ultrastructure. Thus, the generation of ROS does not seem to be the sole major cause of AgNp-mediated cell toxicity in Candida. Rather, the multitargeted action of AgNps, generation of ROS, alterations in ergosterol content, and membrane fluidity together seem to have potentiated anti-Candida action. Thus, this "nano-based drug therapy" is likely to favor broad-spectrum activity, multiple cellular targets, and minimum host toxicity. AgNps, therefore, appear to have the potential to address the challenges in multidrug resistance and fungal therapeutics. PMID- 29593405 TI - Targeted delivery of mannosylated-PLGA nanoparticles of antiretroviral drug to brain. AB - Mannosylated polymeric nanoparticles (NPs) enable improvement of brain bioavailability and reduction of dosing due to efficient drug delivery at the target site. Mannose receptors are present on the surface of macrophages, and therefore, in this study, it is expected that mannosylated NPs of anti-human immunodeficiency virus drug may target the macrophages, which may improve the therapeutic outcome and reduce the toxicity of antiretroviral bioactives. Poly(lactic-co-glycolic acid) (PLGA) and mannosylated-PLGA NPs (Mn-PLGA NPs) were prepared and administered by intravenous route in a dose of 10 mg/kg. After predetermined time period, the pharmacokinetics and biodistribution of NPs were analyzed using high-performance liquid chromatography and confocal microscopy, respectively. Results of this study indicated that Mn-PLGA NPs would be a promising therapeutic system for efficient delivery of the drug into brain macrophages. PMID- 29593406 TI - Curcuminoid-loaded poly(methyl methacrylate) nanoparticles for cancer therapy. AB - Curcuminoids (Curs), oleoresins from Curcuma longa L., have known anticarcinogenic and anti-inflammatory properties, but high toxicity, poor aqueous solubility and susceptibility to degradation in body fluids are deterrents to their clinical administration. Poly(methyl methacrylate) nanoparticles (PMMA-NPs) are biocompatible and resilient and can entrap hydrophobic drugs. The present investigation is related to solubilizing Curs by incorporating them in these nanoparticles (NPs) and is related to a study comparing the anticarcinogenic effect of drug-loaded NPs with free Cur using lung cancer (A549) cell line. Freshly extracted oleoresins were post loaded in PMMA NPs prepared using emulsion polymerization. The presence of the three components of oleoresins was confirmed by thin-layer chromatography. The size and morphology of void and loaded NPs were determined by dynamic light scattering, scanning electron microscopy and transmission electron microscopy. The NPs were spherical with diameters of 192.66+/-5 nm (void) and 199.16+/-5 nm (loaded). Drug loading and encapsulation efficiency were 6% and 93%, respectively. From the Fourier transform infrared spectroscopy spectra, the characteristic absorption vibration of poly(methyl methacrylate) and the bands at 1,383, 1,233 and 962 cm-1 for Cur moiety were observed. Drug release up to 10 days was estimated in buffer, saline and serum. The highest release of ~55% in ~3 days was noted in buffer that exhibited the highest bioavailability. The in vitro anticancer activity of loaded drug was evaluated up to 72 hours by MTT assay using A549 cell line. Cellular uptake of dye-loaded NPs was visualized within 30 minutes of incubation. The results revealed that the dose- and time-dependent cell death in case of loaded PMMA-NPs was comparable to that of free Cur. According to the study, the drug loaded PMMA-NPs appear to be highly suitable for effective, localized and safe chemotherapy. PMID- 29593407 TI - In vitro cytotoxicity of GO-DOx on FaDu squamous carcinoma cell lines. AB - We have synthesized graphene oxide (GO) nanosheets using modified Hummer's method and conjugated it with doxorubicin (DOx), an anticancer drug. Drug release kinetics from GO-DOx conjugate indicated the drug release at acidic pH. MTT assay performed on FaDu hypopharyngeal cancer cell lines revealed that the GO-DOx nanoconjugate inhibited cell proliferation more efficiently compared with pure DOx. Preliminary results indicate the potential of designed GO-DOx drug conjugate for head and neck cancer. PMID- 29593408 TI - Synthesis and characterization of multifunctional gold nanoclusters for application in radiation therapy. AB - Gold nanoparticles, because of their high radiation absorption coefficient and efficient generation of secondary photoelectrons, have been predicted to enhance therapeutic efficacy in radiation therapy. However, high dose for effective treatment limits their use. We have synthesized multifunctional gold nanoclusters (GNCs) that can be used for imaging and radiation therapy. The designed GNCs have been characterized for their physicochemical properties, biocompatibility, and their radiation dose enhancement potential on PC3 cell lines. PMID- 29593409 TI - Effective heart disease prediction system using data mining techniques. AB - The health care industries collect huge amounts of data that contain some hidden information, which is useful for making effective decisions. For providing appropriate results and making effective decisions on data, some advanced data mining techniques are used. In this study, an effective heart disease prediction system (EHDPS) is developed using neural network for predicting the risk level of heart disease. The system uses 15 medical parameters such as age, sex, blood pressure, cholesterol, and obesity for prediction. The EHDPS predicts the likelihood of patients getting heart disease. It enables significant knowledge, eg, relationships between medical factors related to heart disease and patterns, to be established. We have employed the multilayer perceptron neural network with backpropagation as the training algorithm. The obtained results have illustrated that the designed diagnostic system can effectively predict the risk level of heart diseases. PMID- 29593410 TI - Nanosilica-supported liposome (protocells) as a drug vehicle for cancer therapy. AB - This study encompasses the development and comparison of nanosilica-supported liposome (protocells), conventional liposome, and polyethylene glycol (PEG) liposome. An effort was made to study the drug encapsulation efficiency and the in vitro release of the drug, and whether protocells (nanovesicles) could sustain the release of the drug by increasing the residence time, which could reduce the dose-related systemic toxicity of the drug, that is, vincristine sulfate. Nanovesicles had a good encapsulation efficiency (71%), which was comparable to the conventional and PEG-liposome, which were 74% and 78%, respectively. The obtained vesicles were in the size range 100-150 nm, and the drug release efficiency of conventional, PEGylated, and protocells liposome was about 67%, 42%, and 52%, respectively, in 150 minutes. The intermediate value of nanosilica supported liposome indicates the ability for stable and controlled release of the drug, which prevents the rapid burst or slower release of the drug. This study reveals that protocells as nanovesicles could be a better choice for the delivery of cancer drugs such as vincristine sulfate. PMID- 29593411 TI - Imaging of extracellular vesicles derived from human bone marrow mesenchymal stem cells using fluorescent and magnetic labels. AB - Background: Mesenchymal stem cells have been shown therapeutic in various neurological disorders. Recent studies support the notion that the predominant mechanism by which MSCs act is through the release of extracellular vesicles (EVs). EVs seem to have similar therapeutic activity as their cellular counterparts and may represent an interesting alternative standalone therapy for various diseases. The aim of the study was to optimize the method of EV imaging to better understand therapeutic effects mediated by EVs. Methods: The fluorescent lipophilic stain PKH26 and superparamagnetic iron oxide nanoparticles conjugated with rhodamine (Molday ION Rhodamine BTM) were used for the labeling of vesicles in human bone marrow MSCs (hBM-MSCs). The entire cycle from intracellular vesicles to EVs followed by their uptake by hBM-MSCs has been studied. The identity of vesicles has been proven by antibodies against: anti CD9, -CD63, and -CD81 (tetraspanins). NanoSight particle tracking analysis (NTA), high-resolution flow cytometric analysis, transmission electron microscopy (TEM), ELYRA PS.1 super-resolution microscopy, and magnetic resonance imaging (MRI) were used for the characterization of vesicles. Results: The PKH26 and Molday ION were exclusively localized in intracellular vesicles positively stained for EV markers: CD9, CD63, and CD81. The isolated EVs represent heterogeneous population of various sizes as confirmed by NTA. The TEM and MRI were capable to show successful labeling of EVs using ION. Co-culture of EVs with hBM-MSCs revealed their uptake by cells in vitro, as visualized by the co-localization of PKH26 or Molday ION with tetraspanins inside hBM-MSCs. Conclusion: PKH26 and Molday ION seem to be biocompatible with EVs, and the labeling did not interfere with the capability of EVs to re-enter hBM-MSCs during co-culture in vitro. Magnetic properties of IONs provide an additional advantage for the imaging of EV using TEM and MRI. PMID- 29593412 TI - Kaempferol-immobilized titanium dioxide promotes formation of new bone: effects of loading methods on bone marrow stromal cell differentiation in vivo and in vitro. AB - Background: Surface modification of titanium dioxide (TiO2) implants promotes bone formation and shortens the osseointegration period. Kaempferol is a flavonoid that has the capacity to promote osteogenic differentiation in bone marrow stromal cells. The aim of this study was to promote bone formation around kaempferol immobilized on TiO2 implants. Methods: There were four experimental groups. Alkali-treated TiO2 samples (implants and discs) were used as a control and immersed in Dulbecco's phosphate-buffered saline (DPBS) (Al-Ti). For the coprecipitation sample (Al-cK), the control samples were immersed in DPBS containing 50 ug kaempferol/100% ethanol. For the adsorption sample (Al-aK), 50 ug kaempferol/100% ethanol was dropped onto control samples. The surface topography of the TiO2 implants was observed by scanning electron microscopy with energy-dispersive X-ray spectroscopy, and a release assay was performed. For in vitro experiments, rat bone marrow stromal cells (rBMSCs) were cultured on each of the TiO2 samples to analyze cell proliferation, alkaline phosphatase activity, calcium deposition, and osteogenic differentiation. For in vivo experiments, TiO2 implants placed on rat femur bones were analyzed for bone-implant contact by histological methods. Results: Kaempferol was detected on the surface of Al-cK and Al-aK. The results of the in vitro study showed that rBMSCs cultured on Al-cK and Al-aK promoted alkaline phosphatase activity, calcium deposition, and osteogenic differentiation. The in vivo histological analysis revealed that Al-cK and Al-aK stimulated new bone formation around implants. Conclusion: TiO2 implant immobilized kaempferol may be an effective tool for bone regeneration around dental implants. PMID- 29593413 TI - Serum levels of beta-hydroxybutyrate and pyruvate, metabolic changes and cognitive function in patients with schizophrenia during antipsychotic treatment: a preliminary study. AB - Background: beta-hydroxybutyrate (beta-HB) and pyruvate have been associated with the brain energy utilization, which may play a role in the pathophysiology of schizophrenia. In this prospective study, we aim to investigate the trends of beta-HB and pyruvate levels, metabolic changes, and cognitive function in schizophrenia patients receiving antipsychotic treatment. Objective: We recruited 38 schizophrenia patients who had been treated with antipsychotics for 12 weeks, as well as 38 healthy age- and gender-matched subjects. Blood samples were taken from the patients at baseline and week 12 to determine the serum levels of beta HB, pyruvate, and metabolic parameters, while blood samples of the healthy controls were taken at baseline. We evaluated the psychopathology using the Positive and Negative Syndrome Scale and cognitive function using the Brief Assessment of Cognition in Schizophrenia. Results: During the 12-week follow-up period, the beta-HB levels in patients with schizophrenia showed a decreasing trend, particularly in those undergoing treatment with aripiprazole or ziprasidone. The serum levels of beta-HB in patients at baseline and week 12 were both higher than the levels in the healthy controls. Among the schizophrenia patients, changes in beta-HB were positively correlated with changes in executive function. On the other hand, serum pyruvate levels remained steady during the 12 week follow-up period, and we found no significant correlation between pyruvate changes and changes in cognitive function or clinical symptoms. Conclusion: Our findings indicate that beta-HB may possess a potential indicator of energy utilization and have a protective role in executive function in patients with schizophrenia. Additional longitudinal studies with a larger sample size and longer follow-up periods are necessary to identify the relationship of metabolite regulation and cognitive function during schizophrenia patients' exposure to antipsychotics. PMID- 29593414 TI - A low dose of risperidone resolved Charles Bonnet syndrome after an unsuccessful trial of quetiapine: a case report. AB - Charles Bonnet syndrome (CBS) is a diagnosis of exclusion. Typical affected patients have impaired visual acuity, vivid recurring visual hallucinations, and no cognitive impairment. Vision loss is most commonly due to macular degeneration, although many other causes exist. Here, we report a case of an 87 year-old woman with CBS and discuss the diagnosis and treatment. PMID- 29593415 TI - Exercise habituation is effective for improvement of periodontal disease status: a prospective intervention study. AB - Background and purpose: Periodontal disease is closely related to lifestyle related diseases and obesity. It is widely known that moderate exercise habits lead to improvement in lifestyle-related diseases and obesity. However, little research has been undertaken into how exercise habits affect periodontal disease. The purpose of this study was to examine the effect of exercise habits on periodontal diseases and metabolic pathology. Methods: We conducted a prospective intervention research for 12 weeks. The subjects were 71 obese men who participated in an exercise and/or dietary intervention program. Fifty subjects were assigned to exercise interventions (exercise intervention group) and 21 subjects were assigned to dietary interventions (dietary intervention group). This research was conducted before and after each intervention program. Results: In the exercise intervention group, the number of teeth with a probing pocket depth (PPD) >=4 mm significantly decreased from 14.4% to 5.6% (P<0.001), and the number of teeth with bleeding on probing (BOP) significantly decreased from 39.8% to 14.4% (P<0.001). The copy counts of Tannerella forsythia and Treponema denticola decreased significantly (P=0.001). A positive correlation was found between the change in the copy count of T. denticola and the number of teeth with PPD >=4 mm (P=0.003) and the number of teeth with BOP (P=0.010). A positive correlation was also found between the change in the copy count of T. denticola and body weight (P=0.008), low-density lipoprotein cholesterol (P=0.049), and fasting insulin (P=0.041). However, in the dietary intervention group the copy count of T. denticola decreased significantly (P=0.007) and there was no correlation between the number of periodontal disease-causing bacteria and PPD and BOP. Conclusion: Our results are the first to show that exercise might contribute to improvements in periodontal disease.

AB - Background: Fluid management in critically ill patients usually relies on increasing preload to augment cardiac output. In the present study, we aimed to evaluate whether stroke volume variation (SVV) can guide fluid therapy and reduce complications. Patients and methods: In this retrospective study, a total of 88 patients who underwent lobectomy were divided into two groups: group 1 (SVV, n=43) and group 2 (conventional or central venous pressure [CVP], n=45). Heart rate, blood pressure, oxygen saturation, SVV (only group 1), CVP (all patients), urea, creatinine, and hemoglobin levels before and after surgery, use of fluid, blood and inotropic agents, and postoperative complications were recorded retrospectively. Results: The mean age of the study population was 56.9+/-14.4 years and 75% of the patients were male. SVV was used in fluid therapy in 48.9% of the patients. The use of SVV resulted in an increased use of crystalloids and colloids with increased urine output per hour (p<0.05). Of patients in the SVV group and the CVP group, 44.1% and 51.1% developed at least one complication, respectively (p=0.531). The rate of respiratory complications including atelectasis, pneumonia, hypoxemia, and an increased production of secretions was 21% in the SVV group and 37.7% in the CVP group (p=0.104). The rate of complications and the length of hospital stay were comparable between the groups (p>0.05). Conclusion: Our study results showed that the use of SVV increased the use of crystalloids and colloids and favorably affected urine output per hour but did not reduce complications in thoracic surgery. PMID- 29593417 TI - Long-term outcomes and predictors of survival after cardiopulmonary resuscitation for in-hospital cardiac arrest in a tertiary care hospital in Thailand. AB - Background: There are limited data available regarding long-term survival and its predictors in cases of in-hospital cardiac arrest (IHCA) in which patients receive cardiopulmonary resuscitation. Purpose: The objectives of this study were to determine the 1-year survival rates and predictors of survival after IHCA. Patients and methods: Data were retrospectively collected on all adult patients who were administered cardiopulmonary resuscitation from January 1, 2013 to December 31, 2014 in Srinagarind Hospital (Thailand). Clinical outcomes of interest and survival at discharge and 1 year after hospitalization were reviewed. Descriptive statistics and survival analysis were used to analyze the outcomes. Results: Of the 202 patients that were included, 48 (23.76%) were still alive at hospital discharge and 17 (about 8%) were still alive at 1 year post cardiac arrests. The 1-year survival rate for the cardiac arrest survivors post hospital discharge was 72.9%. Prearrest serum HCO3<20 meq/L, asystole, urine <800 cc/d, postarrest coma, and absence of pupillary reflex were predictors of death. Conclusion: Only 7.9% of patients with IHCA were alive 1 year following cardiac arrest. Prearrest serum HCO3<20 meq/L, asystole, urine <800 cc/d, postarrest coma, and absence of pupillary reflex were the independent factors that predicted long-term mortality. PMID- 29593418 TI - miR-622 suppresses tumor formation by directly targeting VEGFA in papillary thyroid carcinoma. AB - Background: MicroRNAs (miRNAs) were reportedly to play crucial roles in papillary thyroid carcinoma (PTC) tumorigenesis and development. Therefore, the discovery of miRNAs may provide a new and powerful tool for diagnosis and treatment of PTC. Purpose: The aim of this study was to investigate the biological function and underlying mechanism of miR-622 in PTC. Materials and methods: The expression levels of miR-622 in PTC patient tissues and cell lines were determined by quantitative RT-PCR (qRT-PCR). The biological function including cell proliferation, colony formation, migration and invasion, as well as underling mechanism of miR-622 in PTC, were also evaluated by a series of in vitro and in vivo experiments. Results: miR-622 expression level was significantly downregulated in PTC tissues and cell lines. Decreased miR-622 expression was associated with advanced clinical stage and lymph node metastasis (P<0.01). The overexpression of miR-622 in TPC-1 cells inhibited cell proliferation, migration and invasion in vitro, as well as suppress tumor growth in vivo. Moreover, we also demonstrated that miR-622 specifically targeted the 3'-UTR regions of vascular endothelial growth factor A (VEGFA) and inhibited its expression both mRNA level and protein levels. Overexpression of VEGFA reversed miR-622-mediated inhibition effect on cell proliferation, migration and invasion in thyroid cancer cells. More importantly, VEGFA expression was significantly increased and inversely correlated with the levels of miR-622 in PTC tissues. Conclusion: These results show that miR-622 acts as a tumor suppressor in thyroid cancer, at least in part, via targeting VEGFA, and suggest that miR-622 may serves as a potential target for treatment of thyroid cancer patients. PMID- 29593420 TI - Novel long noncoding RNA GACAT3 promotes colorectal cancer cell proliferation, invasion, and migration through miR-149. AB - Aim: To explore the expression and clinical significance of long noncoding RNA (lncRNA) gastric cancer-associated transcript 3 (GACAT3) in human colorectal cancer (CRC). Methods: Expression of GACAT3 in CRC tissues and cell lines was measured using quantitative real-time PCR. CCK-8 and colony formation assays were used to assess the effect of GACAT3 on CRC cell line proliferation. Transwell invasion and migration assays were performed to detect the effect of GACAT3 on CRC cell line invasion and migration. Bioinformatics prediction, luciferase reporter assay, and pull-down assay were used to determine if miR-149 was a target of GACAT3. In addition, we also conducted colony formation assays and invasion assays to verify that GACAT3 promotes tumor progression through miR-149. Finally, in vivo tumorigenesis studies were used to demonstrate subcutaneous tumor growth. Results: In the present study, we found that GACAT3 was highly expressed in CRC tissues and cell lines. Si-GACAT3 significantly decreased cell proliferation, motility, and invasiveness both in vitro and in vivo. We confirmed that downregulated GACAT3 significantly increased the expression of miR-149, and miR-149 binds to GACAT3 in a sequence-specific manner using luciferase reporter assays and pull-down assay. Further functional experiments indicated that GACAT3 could directly upregulate SP1 and STAT3 expressions by functioning as a competing endogenous RNA for miR-149, and consequentially, promoting CRC cell proliferation and invasion in vitro. Conclusion: This study demonstrated that GACAT3 promotes tumor progression through competitive binding to miR-149 and suggests a promising new strategy for anti-CRC therapy. PMID- 29593419 TI - Functional miRNAs in breast cancer drug resistance. AB - Owing to improved early surveillance and advanced therapy strategies, the current death rate due to breast cancer has decreased; nevertheless, drug resistance and relapse remain obstacles on the path to successful systematic treatment. Multiple mechanisms responsible for drug resistance have been elucidated, and miRNAs seem to play a major part in almost every aspect of cancer progression, including tumorigenesis, metastasis, and drug resistance. In recent years, exosomes have emerged as novel modes of intercellular signaling vehicles, initiating cell-cell communication through their fusion with target cell membranes, delivering functional molecules including miRNAs and proteins. This review particularly focuses on enumerating functional miRNAs involved in breast cancer drug resistance as well as their targets and related mechanisms. Subsequently, we discuss the prospects and challenges of miRNA function in drug resistance and highlight valuable approaches for the investigation of the role of exosomal miRNAs in breast cancer progression and drug resistance. PMID- 29593421 TI - Forecast of actin-binding proteins as the oncotarget in osteosarcoma - a review of mechanism, diagnosis and therapy. AB - Osteosarcoma (OS) is the most common bone malignant tumor with a high rate of lung metastasis and principally emerges in children and adolescents. Although neoadjuvant chemotherapy is widely used around the world, a high rate of chemoresistance occurs and frequently generates a poor prognosis. Therefore, finding a new appropriate prognostic marker for OS is a valuable research direction, which will give patients a better chance to receive proper therapy. Actin-binding proteins (ABPs) are a group of proteins that interact with actin cytoskeleton and play a crucial role in the regulation of the cell motility and morphology in eukaryotes. Meanwhile, ABPs also act as a bridge between the cytomembrane and nucleus, which transmit the outside-in and inside-out signals in cytoplasm. Furthermore, ABPs alter the dynamic structure of actin and regulate the invasion and metastasis of cancer. Hence, ABPs have a wide application in predicting the prognosis, and may be new targets, in tumor therapy. This review focuses on a series of ABPs and discusses their modulatory functions. It provides a new insight into the classification of ABPs' functions in the process of invasion and metastasis in OS and illuminates the potential ability in predicting the prognosis of OS patients. PMID- 29593422 TI - Overexpression of HHLA2, a member of the B7 family, is associated with worse survival in human colorectal carcinoma. AB - Background: Colorectal carcinoma (CRC) is one of the most common malignancies, and immunotherapy has opened a new field of cancer treatment in recent years. Generally, CRC does not benefit from immunotherapy. HHLA2, a member of the B7 family, is a novel immune checkpoint molecule, and the prognostic value of HHLA2 in CRC patients and the association between HHLA2 expression and clinicopathological characteristics remains unknown. Materials and methods: This study included 63 patients diagnosed with CRC, and their resected specimens were obtained and constructed as a tissue microarray. Expression of HHLA2 and CD8 was detected by the double immunohistochemistry method. Based on follow-up data, correlations of HHLA2 expression and clinicopathological features, including overall survival, in CRC patients were evaluated. Results: High HHLA2 expression was detected in CRC tumor tissues, compared to the adjacent noncancerous tissues. HHLA2 expression level was significantly related to the depth of invasion (P=0.044) and CD8+ T-cell infiltration status (P=0.016), and predicted high mortality rate (P=0.035). HHLA2 acted as an independent predictive factor in the overall survival of CRC patients (P=0.039, hazard ratio=2.162, 95% CI 1.041 3.084). Conclusion: HHLA2 expression is upregulated in CRC patients, and HHLA2 is an independent prognostic factor of overall survival of CRC patients. High HHLA2 expression is closely correlated with CD8 T-cell infiltration status and can predict poor prognosis in CRC patients. PMID- 29593423 TI - High expression of COL10A1 is associated with poor prognosis in colorectal cancer. AB - Background: High expression of collagen type X alpha 1 chain (COL10A1), a member of the collagen family, had been observed in various human cancers, but the detailed function and molecular mechanism of COL10A1 were largely unclear. Aim: The aim of this study was to investigate the expression of COL10A1 in colorectal cancer (CRC) tissues and cells and to reveal its biological function and mechanism in CRC. Materials and methods: Immunohistochemistry (IHC), real-time quantitative polymerase chain reaction (QPCR) and Western blot experiments were used to determine the clinical relevance between expression levels of COL10A1 and CRC. Results: Compared with normal tissues, COL10A1 expression was significantly higher in CRC tissues. Biological functional experiments showed that overexpression of COL10A1 enhanced proliferation, migration, and invasion of CRC cells, and knockdown of COL10A1 inhibited tumorigenesis in vivo. Western blot assays showed that COL10A1 promoted the process of epithelial-mesenchymal transition (EMT). The overexpression of COL10A1 was associated with adverse prognosis in CRC by tissue microarray (TMA) analysis. Conclusion: Our findings had provided evidences to support the fact that COL10A1 was abnormally up expressed in CRC and involved in the progression of CRC and the process of EMT. Furthermore, we demonstrated that the high-level expression of COL10A1 was an independent risk factor of prognosis and overall survival in CRC patients. These suggested that COL10A1 might be a new potential target for cancer therapy in the future. PMID- 29593424 TI - Hsp90 inhibitor NMS-E973 exerts the anticancer effect against glioblastoma via induction of PUMA-mediated apoptosis. AB - Background: Glioblastoma is one of the most aggressive and common malignancies of the central nervous system in humans. Owing to the correlation of high Hsp90 expression with prognosis and clinical pathology features of diverse types of cancer, targeting Hsp90 with small-molecule inhibitors has become a promising anticancer strategy. Purpose: In this study, we aimed to explore the possibility of anticancer effect of NMS-E973 in giloblastoma and elucidate the mechanism. Methods: Cell based MTT assay and colony formation assay were used to detect cell viability. Apoptosis was analyzed by nuclear staining with Hoechst 33258 and Annexin V/propidium iodide staining followed by flow cytometry. Western-blot and RT-PCR were used to detect gene expression. Xenograft assay was used to explore the anticancer effect of NMS-E973 in vivo. Results: We found that NMS-E973 induces apoptosis and inhibits cell growth in glioblastoma cells in cell culture and xenograft models. As a proapoptotic Bcl-2 member, PUMA was induced by NMS E973 in a p53-dependent manner in glioblastoma in cell culture, thereby inducing apoptosis in glioblastoma cells. Furthermore, PUMA was induced by NMS-E973 treatment in xenograft tumors, and deficiency in PUMA significantly suppressed the antitumor effects of NMS-E973. Conclusion: Our study suggests that PUMA mediated apoptosis is important for the therapeutic responses of NMS-E973. Induction of PUMA might be a potential biomarker for predicting NMS-E973 responses. PMID- 29593425 TI - Lung squamous cell carcinoma associated with hypoparathyroidism with sensorineural deafness and renal dysplasia syndrome: a case report. AB - Hypoparathyroidism with sensorineural deafness and renal dysplasia (HDR) syndrome is an autosomal dominant condition caused by mutations of the gene encoding the dual zinc-finger transcription factor, GATA3. A previous study identified some patients with GATA3 gene variants and breast cancer, suggesting that GATA3 variants may contribute to tumorigenesis in estrogen receptor 1-positive breast tumors; however, these patients did not have HDR syndrome. A 32-year-old nonsmoking Japanese woman was histologically diagnosed with lung squamous cell carcinoma associated with HDR syndrome and a c.C952T>C (p.C318R) germline mutation in GATA3. This is the first report describing cancer in a patient with HDR syndrome. Our data indicates that GATA3 mutations may be a potential therapeutic target for lung cancer. PMID- 29593426 TI - Clinical and economic impact of the 21-gene recurrence score assay in adjuvant therapy decision making in patients with early-stage breast cancer: pooled analysis in 4 Basque Country university hospitals. AB - Purpose: The 21-gene recurrence score (RS) is a genomic test developed as a prognostic and predictive tool to improve the treatment decision making in cases of estrogen receptor-positive and human epidermal growth factor receptor 2 negative early-stage breast cancer. This study examined the clinical and economic impact of its use in 4 Basque Country university hospitals. Methods: Taking into consideration the RS result, we recorded the recommended initial systemic adjuvant therapy (endocrine therapy with or without chemotherapy) according to standard clinicopathologic factors and the final decision about chemotherapy. Then, if the RS was high, chemotherapy was recommended; it was not recommended if the RS was low; for those with an intermediate RS, clinicopathologic factors were considered, and the initial recommendation based on those factors was maintained. In addition, the probability of switching treatment was calculated. Then, we developed an economic evaluation by measuring the treatment's incremental short term budget impact from both the societal perspective and that of the Basque Health System. Patients' characteristics and chemotherapy use were analyzed using logistic regressions and receiver operating characteristic curves. Results: Without an RS, chemotherapy would have been prescribed to 56% of 401 patients, but, with RS use, that percentage decreased to 25. The overall rate of decision change was 35.4%. Test inclusion led to a reduction in chemotherapy costs of ?922 per patient in the total population. Although this reduction did not entirely offset the cost of the test, the productivity loss per patient was reduced by ?1,977. Conclusion: The 21-gene RS test significantly changed the indication for chemotherapy. As chemotherapy treatments with no benefit were avoided, patients' quality of life was improved. The short-term economic impact was negative for the Basque Health Service, but savings resulted when sick-leave costs were included. PMID- 29593428 TI - Can patient safety be improved by reducing the volume of "inappropriate prescribing tasks" handed over to out-of-hours junior doctors? AB - Background: First-year doctors found that during out-of-hours shifts they were being delayed and distracted from reviewing potentially sick/deteriorating patients by a high volume of prescribing tasks. This predominately consisted of oral anticoagulation prescribing and rewrites of drug charts. We hoped that if we could reduce this burden of "inappropriate prescribing tasks", we could not only improve junior doctors' job satisfaction and opportunities for training but also give them more time for patient reviews. Methods: Three weekends were initially audited to quantify the number of "inappropriate prescribing tasks" using data from the hospital's computerized task assigning system. On three subsequent weekends, a checklist was handed out to the ward teams on Friday mornings. This checklist was designed to encourage the day teams to check that drug charts would not need oral anticoagulation or rewriting over the weekend. Results: An overall reduction in "inappropriate prescribing tasks" of 46% with a specific reduction in inappropriate oral anticoagulation prescribing of 65% was observed. Inappropriate drug chart rewrites were reduced by 30%. The reduction in the mean number of pre-intervention inappropriate prescribing tasks (as a percentage of total prescribing tasks) and the post-intervention mean was 6.94% (95% confidence interval -0.54 to 14.42, p-value=0.062). Conclusion: Improved job satisfaction and a perceived reduced workload were noted from post-intervention qualitative surveys. While improved patient safety directly resulting from this intervention is more difficult to establish, and the observed reduction in inappropriate prescribing was only approaching statistical significance, our colleagues commented in post-intervention feedback that they felt they had more time, and felt less pressured, while attending patients. The workload of junior doctors can exert a significant effect on patient care, and simple measures can alleviate this burden. Furthermore, computerized hospital task management systems are an underutilized source of data for audit and quality improvement. PMID- 29593427 TI - Glucagon-like peptide-1 exerts anti-inflammatory effects on mouse colon smooth muscle cells through the cyclic adenosine monophosphate/nuclear factor-kappaB pathway in vitro. AB - Background: Intestinal smooth muscle cells (SMCs) undergo substantial morphological, phenotypic, and contractile changes during inflammatory bowel disease (IBD). SMCs act as a source and target for different inflammatory mediators, however their role in IBD pathogenesis is usually overlooked. Glucagon like peptide-1 (GLP-1) is an incretin hormone reported to exert multiple anti inflammatory effects in different tissues including the gastrointestinal tract through various mechanisms. Aim: The aim of this research is to explore the effect of GLP-1 analog exendin-4 on the expression and secretion of inflammatory markers from mouse colon smooth muscle cells (CSMCs) after stimulation with lipopolysaccharide (LPS). Materials and methods: Freshly isolated CSMCs from male BALB/c mice were cultured in DMEM and treated with vehicle, LPS (1 MUg/mL), LPS+exendin-4 (50 nM), or LPS+exendin-4 (100 nM) for 24 h. Expression of inflammatory cytokines was then evaluated by antibody array membrane. Results: CSMCs showed basal expression of several cytokines which was enhanced with the induction of inflammation by LPS. However, exendin-4 (50 and 100 nM) significantly (p<0.05) reduced the expression of multiple cytokines including tumor necrosis factor-alpha (TNF-alpha), interleukin-1alpha (IL-1alpha), T cell activation gene-3 (TCA-3), stromal cell-derived factor-1 (SDF-1), and macrophage colony stimulating factor (M-CSF). To confirm these results, expression of these cytokines was further assessed by enzyme-linked immunosorbent assay and real-time polymerase chain reaction and similar results were also observed. Moreover, secretion of TNF-alpha and IL1-alpha into the conditioned media was significantly downregulated by exendin-4 when compared to LPS-treated cells. Furthermore, LPS increased NF-kappaB phosphorylation, while exendin-4 significantly reduced levels of NF-kappaB phosphorylation. Conclusion: These data indicate that GLP-1 analogs can exert significant anti-inflammatory effects on CSMCs and can potentially be used as an adjunct treatment for inflammatory bowel conditions. PMID- 29593429 TI - Upregulation of Arp2 expression is associated with the prognosis and prediction of lymph node metastasis in bladder urothelial carcinoma. AB - Objective: Upregulation of actin-related protein 2/3 complex subunit 2 (Arp2) is observed in various tumors, but its expression pattern has not been revealed in bladder urothelial carcinoma (BUC). The purpose of this study was to investigate the role of Arp2 expression in the pathological features and the prognosis as well as lymph node metastasis of BUC. Methods: A total of 228 tissue specimens from BUC patients who underwent a radical cystectomy were collected. In addition, 40 lymph node specimens and 40 normal bladder tissue specimens as controls were used. All of the specimens were used to construct a tissue microarray and were subsequently subjected to immunohistochemical staining for Arp2 expression. Logistic and Cox regression analyses and Kaplan-Meier curve analysis were applied to analyze the relation between Arp2 expression and multiple clinical features of patients with BUC. Results: Immunohistochemical staining observation showed that Arp2 was mainly expressed in the cytoplasm and nucleus of positive cells and that Arp2 expression in BUC was significantly higher than that in normal bladder tissues. Arp2 expression in BUC tissues was associated with tumor size, tumor multiplicity, tumor stage, tumor grade, and lymph node metastasis (P < 0.05). Logistic regression analysis demonstrated that Arp2 expression was an independent risk factor for lymph node metastasis of BUC (P < 0.05). Kaplan-Meier curve analysis showed that increased Arp2 expression was associated with a shortened recurrence-free survival (RFS) and overall survival (OS) of BUC patients after radical cystectomy (P < 0.05). Conclusion: These findings suggest that Arp2 is significantly upregulated in BUC tissues when compared with normal bladder tissues, and that Arp2 expression is an independent predictor for lymph node metastasis, RFS, and OS. PMID- 29593430 TI - Prospective study of neoadjuvant chemoradiotherapy using intensity-modulated radiotherapy and 5 fluorouracil for locally advanced rectal cancer - toxicities and response assessment. AB - Aims and objectives: The past 2 decades witnessed the strengthening of evidence favoring the role of neoadjuvant chemoradiation (CHRT) in the treatment of locally advanced rectal cancer. The study aims to evaluate the response and acute toxicities to neoadjuvant CHRT using intensity-modulated radiotherapy (IMRT) in the treatment of rectal cancer. Predictive factors to achieve pathological complete response (pCR) were analyzed, as a secondary endpoint. Materials and methods: All consecutive patients who underwent IMRT as part of neoadjuvant CHRT in the treatment of rectal cancer between August 2014 and December 2016 at a tertiary cancer care center were accrued for the study. The cohort underwent CHRT with IMRT technique at a dose of 50.4 Gy in 28 fractions concurrent with continuous infusion of 5 fluorouracil during the first and the last 4 days of CHRT. Surgery was performed 6 weeks later and the pathological response to CHRT was noted. Results: Forty-three subjects were accrued for the study. Radiation dermatitis and diarrhea were the only observed grade >=3 acute toxicities. Sphincter preservation rate (SPR) was 43.3%. pCR was observed in 32.6%. Univariate and multivariate logistic regression showed that carcinoembryonic antigen was the only independent predictive factor to achieve pCR. Conclusion: IMRT as part of neoadjuvant CHRT in the treatment of locally advanced rectal cancer is well tolerated and gives comparable results with respect to earlier studies in terms of pathological response and SPR. Further randomized controlled studies are needed to firmly state that IMRT is superior to 3-dimensional conformal radiotherapy. PMID- 29593431 TI - Prognostic value of ductal carcinoma in situ component in invasive ductal carcinoma of the breast: a Surveillance, Epidemiology, and End Results database analysis. AB - Background: The prognostic implication of concomitant ductal carcinoma in situ (DCIS) in invasive ductal carcinoma (IDC) remains controversial. Our objective was to investigate whether concomitant DCIS affects survival outcomes in patients with IDC. Materials and methods: Patients with nonmetastatic breast cancer who underwent surgery in 2010-2014 were included from the Surveillance, Epidemiology, and End Results program. Statistical analyses were conducted using chi2 test, linear-by-linear association, one-way analysis of variance, Kaplan-Meier method, Cox proportional hazards regression model, and propensity score matching (PSM). Results: A total of 61,745 patients were identified, including 44,630 (72.3%), 13,559 (22.0%), and 3,556 (5.7%) patients with no DCIS component reported (No DCIS), DCIS <25% (L-DCIS), and >=25% (H-DCIS), respectively. Patients with H-DCIS were more likely to be younger (p<0.001), have smaller tumors (p<0.001), good/moderate differentiation (p<0.001), human epidermal growth factor receptor 2 positive disease (p<0.001), receive mastectomy (p<0.001), and not receive radiotherapy (p<0.001) and chemotherapy (p<0.001). The median follow-up was 27 months, and the 2-year breast cancer-specific survival (BCSS) in patients with No DCIS, L-DCIS, and H-DCIS was 97.3%, 98.0%, and 98.5%, respectively (p<0.001). Before PSM, H-DCIS was an independent favorable prognostic factor for BCSS; patients with H-DCIS had better BCSS compared to patients with No-DCIS (hazard ratio [HR] 0.674, 95% CI: 0.528-0.861, p=0.002), while the BCSS between No-DCIS and L-DCIS was similar (HR 0.944, 95% CI: 0.840-1.061, p=0.334). However, this survival advantage disappeared after PSM; there was significantly different BCSS between patients with No-DCIS and H-DCIS (HR 0.923, 95% CI: 0.653-1.304, p=0.650). H-DCIS was not associated with BCSS as compared to No-DCIS in the breast-conserving surgery (p=0.295) and mastectomy (p=0.793) groups. Conclusion: In breast cancer, patients with H-DCIS have unique clinicopathologic features compared to patients with No-DCIS. Before PSM, H-DCIS was associated with favorable BCSS as compared to No-DCIS. However, the survival advantage disappeared after PSM. PMID- 29593432 TI - Downregulation of hsa_circ_0011946 suppresses the migration and invasion of the breast cancer cell line MCF-7 by targeting RFC3. AB - Introduction: Although some circRNAs have been found to regulate the progression of malignancies, their functions and coupled molecular mechanisms are still unclear. In our study, we sought to assess the underlying molecular mechanisms of circRNAs in breast cancer and therefore explored the differentially expressed circRNAs and co-expression networks, followed by in vitro experiments. Materials and methods: High-throughput RNA sequencing was performed to obtain an unbiased profile of circRNA expression. CircRNA-miRNA-mRNA co-expression networks were predicted, and sequence analyses were carried out. The MTT, transwell migration and invasion assay was conducted in Michigan Cancer Foundation-7 cells that had been transfected with si-circRNA and si-negative control (si-NC). Results: A total of 152 circRNAs were differentially expressed in breast cancer tissues, among which 85 were upregulated and 67 downregulated. Out of these, hsa_circ_0011946 was selected and the subsequent bioinformatics analysis predicted that hsa_circ_0011946 sponging miR-26a/b directly targeted replication factor C subunit 3 (RFC3) and that its knockdown could inhibit RFC3 mRNA and protein expression. Furthermore, hsa_circ_0011946 loss-of-function significantly suppressed the migration and invasion of Michigan Cancer Foundation-7 cells. Conclusion: Together, these results indicate that hsa_circ_0011946 and RFC3 comprise a novel pathway involved in the progression of breast cancer. PMID- 29593433 TI - Mechanical ventilation promotes lung metastasis in experimental 4T1 breast cancer lung-metastasized models. AB - Background/purpose: The aim of this study was to test the hypothesis that mechanical ventilation (MV) during cancer surgery induces lung stroma/tissue milieu changes, creating a favorable microenvironment for postoperative lung metastatic tumor establishment. Materials and methods: In Protocol A, female BALB/c mice were divided into an MV group and a control (no MV) group, both of which were anesthetized and subjected to intravenous injection of green fluorescent protein (GFP)-labeled mouse mammary carcinoma cell line (4T1) cells. After 24 h, the lung tissue was removed and the number of GFP-labeled 4T1 cells was calculated. In Protocol B, the clinically relevant mouse model of spontaneous breast cancer lung metastasis was used with surgical resection of the primary tumor to investigate the MV event that dictates postoperative lung metastasis. Female BALB/c mice were inoculated in the mammary fat pad with 4T1 cells. After 14-d growth, mice were anesthetized and divided into an MV group and a control (no MV) group during surgical procedures (mastectomy). Metastatic tumor burden was assessed two weeks after mastectomy by both macroscopic metastatic nodule count, hematoxylin-eosin histology, immunohistochemistry for the macrophage marker (CD68), and epithelial cell adhesion molecule (EpCAM). Results: MV was associated with a significant increase in the number of circulating breast tumor cells (GFP-labeled 4T1 cells) remaining in the microvasculature of the lung (P<0.01). Immunohistochemical results showed increased infiltration of CD68 positive macrophages within injured lung parenchyma and metastatic tumor as well as increased expression of EpCAM in metastatic nodules. Postoperative metastases were more prevalent in the mechanically ventilated mice group compared to the non ventilated group (P<0.05). Conclusion: MV-induced lung metastasis occurs by attracting circulating tumor cells to the site of the lung injury and by accelerating the proliferation of preexisting micro-metastases in the lung. These observations indicate that the metastasis-enhancing effect of MV should be considered in general anesthesia during cancer surgery. PMID- 29593434 TI - Lifestyle in pregnancy and cryptorchidism in sons: a study within two large Danish birth cohorts. AB - Purpose: Cryptorchidism is the most frequent congenital malformation in boys and is associated with low sperm count, infertility and testicular cancer. Unhealthy maternal lifestyle during pregnancy such as smoking, high prepregnancy body mass index (BMI) as well as alcohol and caffeine intake may constitute possible risk factors for cryptorchidism, but results from the few previous studies are conflicting. We aimed to explore the association between maternal lifestyle factors and occurrence of cryptorchidism in sons. Patients and methods: The Danish National Birth Cohort and the Aarhus Birth Cohort provided information on maternal lifestyle from early pregnancy. Data were linked to several Danish health registers, multiple imputation was used to handle missing data and Cox proportional hazards models were used to adjust for potential confounders. Results: In total, 85,923 boys were included, and of them, 2.2% were diagnosed with cryptorchidism. We observed the strongest associations between maternal tobacco smoking and prepregnancy BMI and cryptorchidism. Sons of women who smoked 10-14 cigarettes/day had the highest hazard ratio (HR) for cryptorchidism (1.37; 95% CI: 1.06-1.76), and for maternal BMI >=30 kg/m2, the HR was 1.32 (95% CI: 1.06-1.65). Binge drinking was associated with an HR <1, if the women had one or two episodes in pregnancy (HR: 0.81; 95% CI: 0.67-0.98). Average maternal alcohol intake and caffeine intake during pregnancy were not significantly associated with a higher occurrence of cryptorchidism detected at birth or later in life. Conclusion: Maternal tobacco smoking, overweight and obesity in pregnancy were associated with higher occurrence of cryptorchidism in boys in this study. PMID- 29593435 TI - Mode of delivery is not associated with celiac disease. AB - Purpose: The purpose of this study was to investigate the association between mode of delivery and the risk of celiac disease in two large population-based birth cohorts with different prevalence of diagnosed celiac disease. Patients and methods: This is an observational register-based cohort study using two independent population cohorts. We used data from administrative registers and health administrative registers from Denmark and Norway and linked the data at the individual level. We included all children who were born in Denmark from January 1, 1995 to December 31, 2010 and all children who were born in Norway from January 1, 2004 to December 31, 2012. Results: We included 1,051,028 children from Denmark. Cesarean sections were registered for 196,512 children (18.9%). Diagnosed celiac disease was registered for 1,395 children (0.13%). We included 537,457 children from Norway. Cesarean sections were registered for 90,128 children (16.8%). Diagnosed celiac disease was registered for 1,919 children (0.35%). We found no association between the mode of delivery and the risk of diagnosed celiac disease. The adjusted odds ratio for celiac disease for children delivered by any type of cesarean section compared to vaginal delivery was 1.11 (95% CI: 0.96-1.29) in the Danish cohort and 0.96 (95% CI: 0.84-1.09) in the Norwegian cohort. The adjusted odds ratio for celiac disease for children delivered by elective cesarean section compared to vaginal delivery was 1.20 (95% CI: 1.00-1.43) in the Danish cohort and 0.96 (95% CI: 0.79-1.17) in the Norwegian cohort. Conclusion: In this large registry-based study, mode of delivery was not associated with an increased risk of diagnosed celiac disease. PMID- 29593436 TI - Comparing methods to combine functional loss and mortality in clinical trials for amyotrophic lateral sclerosis. AB - Objective: Amyotrophic lateral sclerosis (ALS) clinical trials based on single end points only partially capture the full treatment effect when both function and mortality are affected, and may falsely dismiss efficacious drugs as futile. We aimed to investigate the statistical properties of several strategies for the simultaneous analysis of function and mortality in ALS clinical trials. Methods: Based on the Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) database, we simulated longitudinal patterns of functional decline, defined by the revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R) and conditional survival time. Different treatment scenarios with varying effect sizes were simulated with follow-up ranging from 12 to 18 months. We considered the following analytical strategies: 1) Cox model; 2) linear mixed effects (LME) model; 3) omnibus test based on Cox and LME models; 4) composite time-to-6-point decrease or death; 5) combined assessment of function and survival (CAFS); and 6) test based on joint modeling framework. For each analytical strategy, we calculated the empirical power and sample size. Results: Both Cox and LME models have increased false-negative rates when treatment exclusively affects either function or survival. The joint model has superior power compared to other strategies. The composite end point increases false-negative rates among all treatment scenarios. To detect a 15% reduction in ALSFRS-R decline and 34% decline in hazard with 80% power after 18 months, the Cox model requires 524 patients, the LME model 794 patients, the omnibus test 526 patients, the composite end point 1,274 patients, the CAFS 576 patients and the joint model 464 patients. Conclusion: Joint models have superior statistical power to analyze simultaneous effects on survival and function and may circumvent pitfalls encountered by other end points. Optimizing trial end points is essential, as selecting suboptimal outcomes may disguise important treatment clues. PMID- 29593437 TI - Calculating reading ease score of patient package inserts in Iran. AB - Background: The patient package inserts (PPIs), which contain the necessary information about medications intended for patients, need to be expressed in a clear language comprehensible to everyone. Objective: This study aimed to evaluate the readability and understandability of the drug package inserts for the inexpert people. Methods: The readability of the 158 PPIs of the 33 drugs, registered and manufactured in Iran, was calculated. The main criterion for selecting PPIs to include in this study was of those top-selling drugs during the year 2015 according to the Social Security Organization in Iran. The PPIs were collected from the pharmacies of the three major cities, namely, Tabriz, Ardabil and Meshgin Shahr. Then, using the Flesch-Dayani readability (FDR) tool adjusted for the Persian language, the average number of the words and syllables was counted to calculate and grade the readability score of the selected PPIs. Results: This study showed that the average FDR readability score for all the 33 drugs is 52.52, which are graded 10th-11th. Of the PPIs, 70.89% were difficult to read, and on average, the readability of the PPIs was five times difficult than the standard ones. Only 13.92% PPIs were suitable for the 5th-7th grade, and 15.19% of the package inserts ranked in the 8th-9th reading grade. Conclusion: A considerable number of the PPIs in Iran have low readability level and were not suitable for the inexpert readers. Since the treatment cost is very high, people tend to use medications arbitrarily or simply use old prescriptions. This study suggests the necessity of a major improvement in the readability level of the PPIs in order to ensure the usefulness of the PPIs to the majority of the consumers. PMID- 29593439 TI - Student, Faculty, and Staff Approval of University Smoke/Tobacco-Free Policies: An Analysis of Campus Newspaper Articles. AB - Objective: To provide a nontraditional source of data to university policymakers regarding student, faculty, and staff approval of university smoke/tobacco-free policies, as published through campus newspaper articles. Methods: From January to April 2016, a total of 2523 articles were retrieved concerning campus smoking/tobacco at 4-year, public universities. Of these, 54 articles met the inclusion factors, which described 30 surveys about campus approval of tobacco free policies and 24 surveys about smoke-free policies. Results: In all, the surveys included more than 130 000 respondents. With the exception of 4 surveys, all reported that the most of the respondents approved a tobacco/smoke-free campus policy. Conclusions: Although the study had several limitations, the findings provide a synthesis from a nontraditional data source that is consistent with findings from the peer-reviewed literature, in which most of the students, faculty, and staff on university campuses approve of smoke/tobacco-free campus policies. PMID- 29593438 TI - Glenohumeral internal rotation deficit in throwing athletes: current perspectives. AB - Glenohumeral internal rotation deficit (GIRD) is an adaptive process in which the throwing shoulder experiences a loss of internal rotation (IR). GIRD has most commonly been defined by a loss of >20 degrees of IR compared to the contralateral shoulder. Total rotational motion of the shoulder is the sum of internal and external rotation and may be more important than the absolute value of IR loss. Pathologic GIRD has been defined as a loss of IR combined with a loss of total rotational motion. The leading pathologic process in GIRD is posterior capsular and rotator-cuff tightness, due to the repetitive cocking that occurs with the overhead throwing motion. GIRD has been associated with numerous pathologic conditions, including posterior superior labral tears, partial articular-sided rotator-cuff tears, and superior labral anterior-to-posterior tears. The mainstay of treatment for patients with GIRD is posterior capsular stretching and strengthening to improve scapular mechanics. In patients who fail nonoperative therapy, shoulder arthroscopy can be performed. Arthroscopic surgery in the high-level throwing athlete should be to restore them to their functional baseline with the minimum amount of intervention possible. PMID- 29593440 TI - Graves Disease in Central Ghana: Clinical Characteristics and Associated Factors. AB - Background: Graves disease (GD) has increased in prevalence over the past decade in Africa. Despite this, the condition is not well described, especially in sub Saharan Africa. Objective: We have described the clinical characteristics and associated factors of GD in a cohort of patients attending a resource-limited setting tertiary hospital. Methods: Patients were examined thoroughly and systematically tested for the degree of clinical and biochemical thyroid status. Thyroid volume, characteristics, and blood flow were assessed at presentation using ultrasonography. Factors associated with an inability to achieve clinical and biochemical thyroid remission were evaluated using multiple logistic regression analysis. Results: Overall, 182 patients were studied, 152 (83.5%) were women with a female:male ratio of 5.1:1.0. The mean age at presentation was 39.9 +/- 14.7 years with women significantly older than men. Thyroid-associated orbitopathy (TAO) was observed in 56% of the participants and pretibial myxoedema in 6%. About 84% of the participants were hyperthyroid at presentation, 9% were euthyroid, 4% were hypothyroid, and 3% had subclinical hyperthyroidism. Inability to achieve biochemical and clinical remission at 24 months was associated with increased thyroid volume (odds ratio [OR]: 2.35, 95% confidence interval [CI]: 1.85-2.52, P < .001), presence of TAO (OR: 2.15, 95% CI: 2.12-2.33, P < .001), increased FT3/FT4 ratio (OR: 1.33, 95% CI: 1.24-2.56, P = .004), and missed clinic appointment (OR: 5.2, 95% CI: 4.55-7.89, P < .001). Conclusions: Graves disease among Ghanaians is associated with significant signs at presentation. Inability to achieve remission within the first 24 months is associated with increased thyroid volume, TAO, an increased FT3/FT4 ratio, as well as missed clinic appointment. PMID- 29593441 TI - Learning style preferences of dental students at a single institution in Riyadh, Saudi Arabia, evaluated using the VARK questionnaire. AB - Background: Students differ in their preferred methods of acquiring, processing, and recalling new information. The aim of this study was to investigate the learning style preferences of undergraduate dental students and examine the influence of gender, Grade Point Average (GPA), and academic year levels on these preferences. Methods: The Arabic version of the visual, aural, read/write, and kinesthetic (VARK) questionnaire was administered to 491 students from the first- to the fifth-year academic classes at the College of Dentistry, King Saud University. Descriptive statistics were used to characterize the learning styles of the students, and Chi-square test and Fisher's test were used to compare the learning preferences between genders and among academic years. Significance was set at a p-value of <0.05. Results: A total of 368 dental students completed the questionnaire. The multimodal learning style was preferred by 63.04% of the respondents, with the remaining 36% having a unimodal style preference. The aural (A) and the kinesthetic (K) styles were the most preferred unimodal styles. The most common style overall was the quadmodal (VARK) style with 23.64% having this preference. These differences did not reach statistical significance (p>0.05). Females were more likely to prefer a bimodal learning style over a unimodal style (relative risk =2.37). Students with a GPA of "C" were less likely to have a bimodal or a quadmodal style preference compared to students with a GPA of "A" (relative risk =0.34 and 0.36, respectively). Second-year students were less likely to prefer a bimodal over a unimodal style compared to first-year students (relative risk =0.34). Conclusion: The quadmodal VARK style is the preferred learning method chosen by dental students, followed by unimodal aural and kinesthetic styles. Gender was found to influence learning style preferences. Students with a "C" GPA tend to prefer unimodal learning style preferences. The VARK questionnaire is a relatively quick and simple tool to reveal the learning style preferences on an individual or a group level. Dental educators should adjust their delivery methods to approximate the learning preferences of their students. Dental students are encouraged to adapt a multimodal style of learning to improve their academic results. PMID- 29593442 TI - Combined thickness of the uterus and placenta and ultrasonographic examinations of uteroplacental tissues in normal pregnancy, placentitis, and abnormal parturitions in heavy draft horses. AB - The combined thickness of the uterus and placenta (CTUP) and ultrasonographic images of uteroplacental tissues were investigated in 35 pregnant heavy draft horses in Months 7-12 of pregnancy. The mares were divided into three groups: those pathologically diagnosed as placentitis (placentitis group, n=3); those who had abortion, premature birth, or fetal malformation (abnormal group, n=7); and those who had no abnormal findings (normal group, n=25). In the normal group, CTUP increased as pregnancy progressed from Months 7 (median, 7.08 mm; range, 5.68-11.27) to 12 (13.31 mm; 7.44-16.31 mm) (P<0.05) and was higher than those reported previously in Thoroughbred, quarter, and American paint horses. Values of CTUP greater than the 75th percentile of the normal group from Months 7 (7.54 mm) to 12 (15.19 mm) were detected in 100% of the placentitis group (3/3) and in 86% of the abnormal group (6/7). Ultrasonographic images showing placental separation were obtained in 67% of the placentitis group (2/3), 29% of the abnormal group (2/7), and 20% of the normal group (5/25). Pathological placental edema and ultrasonographic images showing uteroplacental roughness or distinguishability were observed even in the normal group. These findings suggest that increased CTUP and placental separation would reflect placentitis and abnormal pregnancies and may help to detect them in heavy draft horses. PMID- 29593443 TI - Displacement of the large colon in a horse with enterolithiasis due to changed positions observed by computed tomography. AB - Computed tomography (CT) was performed for an 18-year-old female pony with enterolithiasis in the prone and supine positions. CT images from the prone position revealed displacement of the large dorsal colon, which contained an enterolith to the ventral side of the abdomen, and those from the supine position revealed displacement to the dorsal side. A high-density material suggestive of a metallic foreign body was also observed in the enterolith core. An enterolith (422 g, 104 mm) was surgically removed from the large dorsal colon. This caused no complications after surgery and increased the horse's weight. Changing positions during CT helps identify the exact location of enterolith and intestinal displacement due to enterolith weight, as well as size and number. PMID- 29593444 TI - Blood glucose is unlikely to be a prognostic biomarker in acute colitis with systemic inflammatory response syndrome in Thoroughbred racehorses. AB - Although hyperglycemia at admission with colic has been reported to have a poor prognosis, there is no report specifically about acute colitis with systemic inflammatory response syndrome (SIRS) in horses. In this study, we measured blood glucose (Glu), insulin (Ins), and cortisol (Cor) levels in 17 Thoroughbred racehorses diagnosed as having acute colitis with SIRS, and examined the relationship between time-dependent changes in Glu, Ins, and Cor and prognosis. Glu levels were high in 3 horses at admission, but thereafter no horses had persistently high Glu levels. There was no significant difference in Glu, Ins, and Cor levels within 72 hr between surviving and non-surviving horses. In conclusion, the Glu level is unlikely to be a useful prognostic biomarker in acute colitis with SIRS. PMID- 29593445 TI - Effect of selection for eventing on the MSTN gene in Brazilian sport horses. AB - Polymorphisms in MSTN have previously been associated with equine performance. Therefore, the aim of this study was to identify variants in MSTN intron 1 in 16 Brazilian Sport Horses selected for competition in eventing and their possible effects of selection on performance. Among the nine variants identified, eight had already been reported in previous studies or genomic databases, although they showed differences in frequencies when compared with other horse breeds. Moreover, a new mutation was identified in two horses, both in heterozygous form. Considering the absence of molecular studies in this valuable Brazilian breed, these findings represent an important contribution to the characterization of its genetic profile and may possibly aid in further genotype-phenotype association studies. PMID- 29593446 TI - Characterization of isolates of Bordetella bronchiseptica from horses. AB - Bordetella bronchiseptica is a well-known Gram-negative bacterial pathogen causing a plethora of diseases in different animals. Although its infection has been reported from pigs and dogs in India, no report of B. bronchiseptica from horses is described. We report for the first time, isolation, identification and characterization of strains of B. bronchiseptica from respiratory infection in horses from different states in India. The antimicrobial susceptibility testing showed resistance to penicillins, ceftazidime, and chloramphanicol. The virulence capability of the strains was confirmed by sequencing genes such as adenylate cyclase toxin (cyaA), bordetella virulence gene (bvgA) and by PCR detection of flagellin gene (fla). We demonstrate the involvement of B. bronchiseptica strains in respiratory tract infection in horses in India. PMID- 29593447 TI - Reducing psychopathic violence: A review of the treatment literature. AB - Psychopathy reflects a pathological form of personality that predisposes individuals to risk for perpetration of chronic and severe violence across their lifespan. The violence attributable to psychopathic persons constitutes a substantial portion of the societal burden to the public health and criminal justice systems and thus necessitates significant attention by prevention experts. However, there is a relatively nascent literature that has examined psychopathic persons' response to treatment, especially considering violence as an outcome. Nevertheless, there have been repeated averments about the amenability (or lack thereof) of psychopathy to treatment. In the present paper, we attempt to provide a comprehensive review of studies assessing the relation of psychopathy to violence outcomes following intervention. Our review of studies suggests there is reason to suspect that specific and tailored interventions which take into consideration psychopathic persons' unique patterns of behavioral conditioning and predispositions may have the potential to reduce violence. However, equally important, certain interventions may potentially exacerbate these persons' violent behavior. The nature of the outcomes is likely highly dependent on the specific components of the intervention itself. We conclude that future research should increase methodological rigor by striving to include treatment control groups and increasing the transparency of the implemented interventions. PMID- 29593449 TI - Different Places, Different Stories: A Study of Spatial Heterogeneity of County Level Fertility in China. AB - Background: China has been characterized by persistently low fertility rates since the 1990s. Existing literature has examined the relationships of fertility levels with social, economic, and policy-related determinants. However, the possible spatial variations in these relationships have not been investigated. Objective: The purpose of this study is to examine the potential spatially varying relationships between county-level fertility rates and policy and socioeconomic factors in China. Methods: Using geocoded 2010 county-level census data, this study adopts the geographically weighted regression (GWR) method to identify place-specific relationships between county-level total fertility rate (TFR) and socioeconomics and policy-related factors. Conclusions: We find relationships between TFR and widely used social, economic, and policy-related factors (rural Hukou, ethnic minority, female education, net migration rate, poor living standard, sex ratio at birth, and fertility policy compliance ratio) vary spatially in terms of the direction, strength, and magnitude. The spatial variation is largely due to the difference in local characteristics. The differences and the complexities of localities cannot be told by a single story of either government intervention or socioeconomic development. Contribution: This study extends the existing fertility research in China by explicitly recognizing the spatial heterogeneity in the impacts of policy and socioeconomic factors on the local fertility rate. This study sets the stage for future research that will contextually analyze varying fertility rates at the sub national level in China and other countries. PMID- 29593451 TI - Editorial. PMID- 29593448 TI - Why psychopathy matters: Implications for public health and violence prevention. AB - Psychopathy is an early-appearing risk factor for severe and chronic violence. The violence largely attributable to psychopathy constitutes a substantial portion of the societal burden to the public health and criminal justice systems, and thus necessitates significant attention from prevention experts. Yet, despite a vast base of research in psychology and criminology, the public health approach to violence has generally neglected to consider this key variable. Fundamentally, the public health approach to violence prevention is focused on achieving change at the population level to provide the most benefit to the maximum number of people. Increasing attention to the individual-level factor of psychopathy in public health could improve our ability to reduce violence at the community and societal levels. We conclude that the research literature on psychopathy points to a pressing need for a broad-based public health approach with a focus on primary prevention. Further, we consider how measuring psychopathy in public health research may benefit violence prevention, and ultimately society, in general. PMID- 29593450 TI - flexsurv: A Platform for Parametric Survival Modeling in R. AB - flexsurv is an R package for fully-parametric modeling of survival data. Any parametric time-to-event distribution may be fitted if the user supplies a probability density or hazard function, and ideally also their cumulative versions. Standard survival distributions are built in, including the three and four-parameter generalized gamma and F distributions. Any parameter of any distribution can be modeled as a linear or log-linear function of covariates. The package also includes the spline model of Royston and Parmar (2002), in which both baseline survival and covariate effects can be arbitrarily flexible parametric functions of time. The main model-fitting function, flexsurvreg, uses the familiar syntax of survreg from the standard survival package (Therneau 2016). Censoring or left-truncation are specified in 'Surv' objects. The models are fitted by maximizing the full log-likelihood, and estimates and confidence intervals for any function of the model parameters can be printed or plotted. flexsurv also provides functions for fitting and predicting from fully-parametric multi-state models, and connects with the mstate package (de Wreede, Fiocco, and Putter 2011). This article explains the methods and design principles of the package, giving several worked examples of its use.

PMID- 29593453 TI - Short Term Hyperthermia Prevents Activation of Proinflammatory Genes in Type B Synoviocytes by Blocking the Activation of the Transcription Factor NF-kappaB. AB - The aim of this study was to investigate the effect and mechanisms of short term hyperthermia on a series of proinflammatory genes in type-B-synoviocytes (fibroblast like synoviocytes - FLS). In vitro experiments demonstrate that exposure of FLS to elevated temperatures for the duration of 30 minutes prevents activation of a series of genes with proinflammatory properties. Exposure to hyperthermia reduces IL-1f3 induced PGE2 release, suppresses activation of the adhesion molecules VCAM-1, ICAM-1, the cytokines TNFa, IL-1a, IL-1p, IL-8 as well as COX-2 protein synthesis. Real time RT-PCR showed that hyperthermia altered gene expression at the transcriptional level. As to the mechanism of inhibition, EMSA experiments demonstrated that exposure of FLS to hyperthermia prevents IL 1f3 induced NF-kappaB translocation and subsequent DNA binding. Many mechanisms have been shown to be involved in hyperthermia mediated effects on NF-kappaB-DNA interactions. We demonstrated by Western blot experiments that in FLS, hyperthermia prevents the phosphorylation and subsequent degradation of IkappaBCC, therefore retaining the NF-kappaB complex in the cytoplasm. Such data might, at least in part, explain and provide a rationale for treating inflammation e.g. associated with rheumatoid arthritis by balneological means.

PMID- 29593455 TI - ABO Mistyping of cis-AB Blood Group by the Automated Microplate Technique. AB - Background: The cis-AB phenotype, although rare, is the relatively most frequent of ABO subgroups in Koreans. To prevent ABO mistyping of cis-AB samples, our hospital has applied a combination of the manual tile method with automated devices. Herein, we report cases of ABO mistyping detected by the combination testing system. Methods: Cases that showed discrepant results by automated devices and the manual tile method were evaluated. These samples were also tested by the standard tube method. The automated devices used in this study were a QWALYS-3 and Galileo NEO. Exons 6 and 7 of the ABO gene were sequenced. Results: 13 cases that had the cis-AB allele showed results suggestive of the cis-AB subgroup by manual methods, but were interpreted as AB by either automated device. This happened in 87.5% of these cases by QWALYS-3 and 70.0% by Galileo NEO. Genotyping results showed that 12 cases were ABO*cis-AB01/ABO*O01 or ABO*cis AB01/ABO*O02, and one case was ABO*cis-AB01/ ABO*A102. Conclusion: Cis-AB samples were mistyped as AB by the automated microplate technique in some cases. We suggest that the manual tile method can be a simple supplemental test for the detection of the cis-AB phenotype, especially in countries with relatively high cis-AB prevalence. PMID- 29593456 TI - Robust Production of Cytomegalovirus pp65-Specific T Cells Using a Fully Automated IFN-gamma Cytokine Capture System. AB - Background: Cytomegalovirus(CMV)-related diseases are a serious cause of morbidity and mortality following hematopoietic stem cell transplantation (HSCT). CMV-specific cytotoxic T lymphocytes (CMV-CTLs) have been reported as an alternative to antiviral drugs that provide long-term CMV-specific immunity without major side effects. However, their application has been limited by the prolonged manufacturing process required. Methods: In this study, we applied the IFN-gamma cytokine capture system (CCS) using the fully automated CliniMACS Prodigy device for rapid production of CMV-CTLs, which may be applicable in clinically urgent CMV-related diseases. Five validation runs were performed using apheresis samples from randomly selected CMV-seropositive healthy blood donors. Successive processes, including antigen stimulation, anti-IFN-gamma labeling, magnetic enrichment and elution, were then performed automatically using the CliniMACS Prodigy, which took approximately 13 h. Results: The original apheresis samples consisted mainly of CD45RA+ CD62L+ naive T cells as well as 0.3% IFN gamma-secreting CD3+ T cells that showed a response to the CMV pp65 antigen (CD3+ IFN-gamma+ cells). Following IFN-gamma enrichment, the target fraction contained 51.3% CD3+ IFN-gamma+ cells with a reduction in naive T cells and selection of CD45RA- CD62L- and CD45RA+ CD62L- memory T cells. Furthermore, extended culture of these isolated cells revealed functional activity, including efficient proliferation, sustained antigen-specific IFN-gamma secretion, and cytotoxicity against pp65-pulsed target cells. Conclusion: The findings reported here suggest that the IFN-gamma CCS by the CliniMACS Prodigy is a simple and robust approach to produce CMV-CTLs, which may be applicable for the treatment of clinically urgent CMV-related diseases. PMID- 29593457 TI - Platelet Count before Peripheral Blood Stem Cell Mobilization Is Associated with the Need for Plerixafor But Not with the Collection Result. AB - Background: A low platelet count before mobilization has recurrently been identified as risk factor for poor mobilization. Methods: To determine the relevance of this finding for peripheral blood stem cell (PBSC) mobilization, including pre-emptive or rescue plerixafor in the case of poor mobilization, we retrospectively analyzed all patients undergoing PBSC collection at our institution between January 2014 and December 2015 (n = 380). Results: In total, 99% of the patients (377/380) successfully collected a minimum of 2 * 106 CD34+ cells/kg body weight sufficient for a single transplant. Rescue or pre-emptive plerixafor was administered to 11% of the patients (42/380). No correlations between the platelet count before mobilization and the number of peripheral blood CD34+ cells or the CD34+ cell collection result were detected in the entire population or the subgroups according to diagnosis (newly diagnosed multiple myeloma, relapsed multiple myeloma, lymphoma, amyloid light-chain amyloidosis, sarcoma, or germ cell tumor). However, patients requiring pre-emptive or rescue plerixafor had a significantly lower platelet count before mobilization (217/nl vs. 245/nl; p = 0.004). Conclusion: With the current state of the art PBSC mobilization strategies, the platelet count before mobilization was not associated with the CD34+ cell collection result but was associated with the need for pre-emptive or rescue application of plerixafor. PMID- 29593458 TI - Reactive Oxygen Species Generated by CD45-Cells Distinct from Leukocyte Population in Platelet Concentrates Is Correlated with the Expression and Release of Platelet Activation Markers during Storage. AB - Background: Platelet stimulation with agonists is accompanied by the generation of reactive oxygen species (ROS) which promotes further platelet activation and aggregation. Considering different cell populations in platelet concentrates (PCs), this study investigates the correlation of ROS generation with the expression and release of platelet activation markers during storage. Methods: Samples obtained from 6 PCs were subjected to flow cytometry and ELISA to evaluate the expression and shedding of platelet P-selectin or CD40L during storage. Intracellular ROS were detected in either CD45- or CD45+ population by flow cytometry using dihydrorhodamine 123, while ROS production was analyzed in both P-selectin+ or P-selectin- and CD40L+ or CD40L- populations. To further evaluate the correlation between ROS generation and release function, TRAP stimulated platelets were also subjected to flow cytometry analysis. Results: ROS detected in the CD45-population (leukocyte-free platelets) was significantly increased by fMLP and PMA. P-selectin- or CD40L- platelet did not show significant amount of ROS. Total ROS generation was significantly increased during platelet storage (day 0 vs. day 5; p = 0.0002) while this increasing pattern was directly correlated with the expression of P-selectin (r = 0.72; p = 0.0001) and CD40L (r = 0.69; p = 0.0001). ROS generations were significantly correlated with ectodomain shedding of these pro-inflammatory molecules. Conclusion: Our data confirmed increasing levels of intracellular ROS generation in both platelets (CD45-) and platelet-leukocyte aggregates (CD45+) during PC storage. The amount of detected ROS is directly correlated with platelet activation and release in each population while platelet-leukocyte aggregates generate higher levels of ROS than single platelets. PMID- 29593459 TI - Post-Operative Iron Carboxymaltose May Have an Effect on Haemoglobin Levels in Cardiothoracic Surgical Patients on the ICU - an Observational Pilot Study about Anaemia Treatment with Intravenous Iron. AB - Background: Post-operative anaemia is associated with increased morbidity and mortality. Positive effects of post-operative intravenous iron (IVI) after elective orthopaedic, abdominal and genitourinary surgery have been reported. The current observational trial investigated the prevalence of post-operative anaemia, the effect of IVI on haemoglobin levels, the use of blood transfusions and diagnoses related to infections. Methods: 1,265 patients on five ICUs of Munster University Hospital were screened for post-operative anaemia. On one ICU, patients were screened for iron deficiency and, if indicated, supplemented with 500 mg of ferric carboxymaltose. Primary outcome measures were haemoglobin levels, C-reactive protein, white blood cell count, transfusion requirements, documented infection and antibiotic treatment. Results: Anaemia was prevalent in 86.2% of patients upon ICU admission. 429 patients were screened for iron deficiency anaemia. 95 patients were eligible, 35 were treated with IVI. An increase of +0.4 g/dl in Hb levels 7 days after IVI compared to -0.1 g/dl in non treated anaemic patients was observed. The number of RBC transfusions, ICD codes related to infections and infectious parameters were similar between groups. Conclusions: IVI treatment was safe and resulted in higher median Hb levels. Randomized controlled trials are required to support the hypotheses of this study. PMID- 29593460 TI - Association of IL-6 C-572G Gene Polymorphism with Anti-E Production. AB - Background: Interleukin 6 (IL-6) is involved in regulation of immunoglobulin production. The aim of this study was to investigate the association between IL-6 single nucleotide polymorphisms (SNPs) in the IL-6 promoter and anti-E in red blood cell (RBC) transfusion recipients. Methods: 50 healthy subjects, 54 patients with RBC alloantibody anti-E (responders), and 45 patients without alloantibody (non-responders) were recruited. All patients were E antigen negative. Results: All healthy subjects and patients had GG at -174 position of IL-6 gene. In our healthy subjects, the frequency of the -572 CC genotype was 58%, that of the -572 CG genotype 38%, and that of the -572 GG genotype 4%. The frequency of G allele of -572 SNP in responders was significantly higher than that in non-responders, (31.5 vs. 16.7%; p = 0.020). The frequency of -572 G positive genotypes (CG and GG) in responders was also significantly higher than that in non-responders, (55.6 vs. 31.1%; p = 0.016). The relative risk of RBC alloimmunization for patients with the -572 G-positive genotype was significantly higher than that of patients with the -572 CC genotype, (1.771 vs. 0.640; p = 0.016). Conclusion: IL-6 C-572G gene polymorphism is significantly associated with anti-E production, with the allele G as a risk allele. PMID- 29593461 TI - Interaction of Platelet-Derived Microparticles with a Human B-Lymphoblast Cell Line: A Clue for the Immunologic Function of the Microparticles. AB - Background: Platelets are blood cells with extensive capabilities in hemostasis. They also play a central role in the development of innate and adaptive immune responses. Little information exists about the immunostimulatory role of platelet derived microparticles (Plt-MPs). To further elucidate this issue, we conducted this study using the B-lymphoblast cell line 'Daudi' as an available surrogate cell line for peripheral blood B lymphocytes. This cell line does not produce immunoglobulins (Igs) and has low expression of activation markers. Methods: Plt MPs were isolated from platelet concentrate (PC) using a multi-step centrifugation method. Daudi cells were treated with Plt-MPs in the culture medium while no treatment was given to the control cells. During 5-day co culture, Daudi cells were evaluated for the Ig production and the expression of the cell surface markers CD86, CD27, and IgD. Results: An increase was observed for the production of IgG and the expression of CD27 and CD86 on Daudi cells in response to Plt-MPs, whereas the IgD level was decreased. The response of Daudi cells was dependent on the concentration of Plt-MPs and the time of their isolation from PCs during storage. The differences of the variables were significant between the treatment and control groups. Conclusion: Plt-MPs could induce the activation and differentiation of immortalized cells of B-cell origin. Thus it is conceivable that Plt-MPs may play a significant role as immortalized cell activators in human monoclonal antibody technology in near future. PMID- 29593462 TI - ABO, Rhesus, and Kell Antigens, Alleles, and Haplotypes in West Bengal, India. AB - Background: Few studies have documented the blood group antigens in the population of eastern India. Frequencies of some common alleles and haplotypes were unknown. We describe phenotype, allele, and haplotype frequencies in the state of West Bengal, India. Methods: We tested 1,528 blood donors at the Medical College Hospital, Kolkata. The common antigens of the ABO, Rhesus, and Kell blood group systems were determined by standard serologic methods in tubes. Allele and haplotype frequencies were calculated with an iterative method that yielded maximum-likelihood estimates under the assumption of a Hardy-Weinberg equilibrium. Results: The prevalence of ABO antigens were B (34%), O (32%), A (25%), and AB (9%) with ABO allele frequencies for O = 0.567, A = 0.189, and B = 0.244. The D antigen (RH1) was observed in 96.6% of the blood donors with RH haplotype frequencies, such as for CDe = 0.688809, cde = 0.16983 and CdE = 0.000654. The K antigen (K1) was observed in 12 donors (0.79%) with KEL allele frequencies for K = 0.004 and k = 0.996. Conclusions: For the Bengali population living in the south of West Bengal, we established the frequencies of the major clinically relevant antigens in the ABO, Rhesus, and Kell blood group systems and derived estimates for the underlying ABO and KEL alleles and RH haplotypes. Such blood donor screening will improve the availability of compatible red cell units for transfusion. Our approach using widely available routine methods can readily be applied in other regions, where the sufficient supply of blood typed for the Rh and K antigens is lacking. PMID- 29593463 TI - Young Blood Rejuvenates Old Bodies: A Call for Reflection when Moving from Mice to Men. AB - Connecting the circulatory system of old and young mice (parabiosis) is documented to have rejuvenating effects on cells, tissues, organs, and functions. A wide range of benefits are envisioned. Blood-based rejuvenation can come to totally change population health and aging. The first blood rejuvenation studies on humans with Alzheimer's disease have started. It puts blood at the center of therapy and revitalizes the historical line of humoral pathology from Hippocrates and Harvey, creating a new type of 'bloodletting.' However, moving from mice to men requires careful consideration. Parabiosis actualizes well-known ethical challenges, such as just distribution of health care, avoiding disparities, and providing equal access to health care resources, as well as issues of human enhancement. However, it also poses new problems. Using internal substances in some persons as means to rejuvenate others calls for ethical reflection. New type of 'blood bonds' may result from the continuous demand for specific types of blood. Even if rejuvenating substances from blood may be artificially and cheaply produced and justly distributed, problems arise: survival may have to be balanced against reproduction, as reproductive age increases. Eternal youth and endless bliss have always been vital human dreams. Although parabiosis may bring us closer to the fountain of youth than ever, it is still too early to provide full fledged assessments of its implications or to foresee how it will change health, aging, medicine, and society. However, in order to bring our reflective abilities on par with our technical skills, we need to start reflection now. PMID- 29593465 TI - Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. I. Surgical Never Events: 1. Urological Wrong Surgery Catastrophes and Disabling Complications. AB - Introduction: Surgical never events are preventable harmful non-intentional human errors. Urology is a common surgical specialty for their occurrence. Patients and Methods: A retrospective search of our center's data was done during the period 2006-2016 for surgical never events. Each included case was studied for the primary diagnosis, procedure, and subspecialty, never event type and timing, needed extra-interventions, urologist/procedure proportioning, outcomes, and possible underlying causes of the event. Results: Of more than 55,000 different urological interventions, 61 patients were involved in never events. Wrong procedures represented 75% of the never events, and endourology and urolithiasis subspecialties were more often involved. The main detectable underlying factor was the disproportion between the levels of the procedure class and the qualification of the urologist (41%). Thirty-four cases had extra-procedures. The short-term harm effect represented the final outcome in 42% of all events. Death, permanent organ loss, and long-term harm represented 20, 15, and 23%, respectively. Conclusion: Urological surgical never events are rare, but their final outcomes could be catastrophic, even leading to death. PMID- 29593466 TI - Using the Modified Clavien Grading System to Classify Complications of Percutaneous Nephrolithotomy. AB - Purpose: A modified Clavien classification system has been proposed to grade perioperative complications. We share our experience in grading the complications of percutaneous nephrolithotomy (PNL), according to this new classification. Methods: A total of 809 PNLs performed between 2010 and 2014 were reviewed retrospectively. The modified Clavien classification system, which classifies the perioperative complications into 5 grades, was applied. Grade wise comparison of complications between the patients with simple and complex calculi was done. We also carried out a univariate analysis of different predictors of complications after surgery. Results: A total of 253 perioperative complications were observed in 237 (29.29%) patients. Most complications were related to bleeding and urinary leakage. Patients with complex calculi had significantly more number of complications across all Clavien groups. In a univariate analysis, positive preoperative urine culture and multiple access for stone clearance were identified to be the independent predictors of complications. Conclusion: The modified Clavien system is a simplistic grading system for classification of postoperative complications. However, it suffers from various shortcomings. Therefore, till the proposition of a more comprehensive classification system, the modified Clavien system is useful for reporting the complications and short term outcomes of PNL. PMID- 29593464 TI - The Emerging Role of Inflammasomes as Central Mediators in Inflammatory Bladder Pathology. AB - Irritative voiding symptoms (e.g. increased frequency and urgency) occur in many common pathologic conditions such as urinary tract infections and bladder outlet obstruction, and these conditions are well-established to have underlying inflammation that directly triggers these symptoms. However, it remains unclear as to how such diverse stimuli individually generate a common inflammatory process. Jurg Tschopp provided substantial insight into this conundrum when, working with extracts from THP-1 cells, he reported the existence of the inflammasome. He described it as a structure that senses multiple diverse signals from intracellular/extracellular sources and pathogens and triggers inflammation by the maturation and release of the pro-inflammatory cytokines interleukin-1beta and interleukin-18. Recently, many of these sensors were found in the bladder and the nucleotide-binding domain, leucine-rich-containing family, pyrin domain containing-3, has been shown to be a central mediator of inflammation in several urological diseases. In this review, we introduce the nucleotide-binding domain, leucine-rich-containing family, pyrin domaincontaining-3 inflammasome, highlight its emerging role in several common urologic conditions, and speculate on the potential involvement of other inflammasomes in bladder pathology. PMID- 29593467 TI - Associations of Transitional Zone Volume with Intraprostatic Chronic Inflammation and Prostate Cancer Risk in Patients Undergoing a First Random Biopsy Set. AB - Objectives: To investigate associations of the transitional zone volume (TZV) with intraprostatic chronic inflammatory infiltrate (CII) and prostate cancer (PCa) risk in patients undergoing a first random biopsy set. Materials and Methods: The study included a homogenous population of 596 patients. The volume of the prostate and TZV were separately measured. Independent associations were investigated by multivariate logistic regression analysis. Results: The median TZV was 18 ml, CII was detected in 157 cases (26.3%), and PCa was present in 292 patients (49%). TZV was the only independent clinical factor associated with CII risk (OR = 1.014). After correcting for CII (OR = 0.276; p < 0.0001), independent factors associated with PCa risk included age (OR = 1.066), prostate specific antigen (OR = 1.177), TZV (OR = 0.919), and an abnormal digital rectal exam (OR = 2.024). Conclusion: In a patient population undergoing a first random prostate biopsy set because of suspected cancer, independent associations were detected among TZV, CII, and PCa. The association between TZV and CII was direct, but the relation between TZV and PCa was inverse. The measurement of the volume of the transitional zone was a useful parameter for evaluating chronic intraprostatic inflammation and PCa risk. PMID- 29593468 TI - The Effect of Human Chorionic Gonadotropin Therapy on Semen Parameters and Pregnancy Rate after Varicocelectomy. AB - Introduction: To study the stimulating effect of human chorionic gonadotropin (hCG) on spermatogenesis in patients with varicocele and infertility undergoing varicocelectomy. Materials and Methods: In the study, 188 infertile patients with varicocele were included. Open inguinal varicocelectomy was performed. They were randomized into 2 groups and hCG (91 patients) was administered intramuscularly by dosage of 5,000 international units every week for 3 months. A semen analysis was obtained at 6 months, post-operatively and cases were followed for 2 years for pregnancy report. Results: Semen analysis of the patients shows a significant improvement in all parameters 6 months after varicocelectomy without any superiority between the 2 groups. During the follow-up, 56 couples (61.5%) in hCG treated and 22 couples (22.7%) in the group treated only by varicocelectomy achieved pregnancy. Patients treated with varicocelectomy plus hCG therapy had a significant superior pregnancy rate compared to the other group (P=0.0001). Conclusion: Administration of hCG in this group of infertile patients might be helpful in order to enhance pregnancy rate. However some more conclusive studies are needed to be able to recommend such therapy for infertile men due to varicocele. PMID- 29593469 TI - Pilot Study to Determine Optimal Stent Duration Following Ureteroscopy: Three versus Seven days. AB - Background/Aims: Many providers elect to place a stent following ureteroscopy for nephrolithiasis, but little data exists on the optimal duration to leave a stent. We sought to determine whether there are any differences in post-operative outcomes for patients with a 3 versus 7-day stent following ureteroscopy. Methods: We retrospectively reviewed 247 patients who underwent unilateral ureteroscopy with lithotripsy, 79 of whom removed a stent with an extraction string at 3 or 7 days post-operatively. These 2 groups were compared with regard to demographic information, pre-operative variables, and post-operative outcomes. Results: Of all patients, 33% experienced a post-procedure related event (phone call, extra clinic visit, and emergency department visit) within 30 days of their procedure, 39% of 3-day stent patients compared to 21% of 7-day patients (p = 0.11). Within the 3 days following stent removal, 3-day stent patients were significantly more likely to have a post-procedure related event than 7-day patients (23 vs. 3%, p = 0.026). Conclusion: One third of patients with a post operative ureteral stent will seek medical care in the 30 days following ureteroscopy. Leaving a stent for 3 versus 7 days may lead to worse outcomes with regard to post-operative events and fank pain. PMID- 29593470 TI - Comparison of Safety, Efficacy and Cost Effectiveness of Photoselective Vaporization with Bipolar Vaporization of Prostate in Benign Prostatic Hyperplasia. AB - Objectives: To compare bipolar vaporization of prostate (BPVP) with photoselective vaporization (PVP) of prostate in the surgical management of benign prostatic hyperplasia in terms of safety, efficacy and cost effectiveness. Methods: Data was analyzed retrospectively for patients who underwent either PVP or BPVP between August 2012 to July 2014 for prostate size <= 80 ml. Preoperative and postoperative period values along with details like operative time, blood loss, hospitalization days, catheter removal time, blood transfusion and etc., were noted down. International prostatic symptom score, quality of life scores, post void residue, and maximum flow rate were recorded preoperatively and postoperatively at each follow-up visit. Follow-up was performed at 1, 3, 6, 12 and 18 months. Results: Similar preoperative characteristics were observed in all the study arms. Hemoglobin drop, transfusion rate, catheter time and hospital days were similar in both the groups. The follow-up data indicates sustainable significant improvement in international prostatic symptom score, quality of life, post void residue and maximum flow rate in both the groups. As expected the cost of the procedure was significantly more in PVP group as compared to BPVP group (p < 0.01). Neither group had severe perioperative complications and no blood transfusion was required in both the groups. Conclusion: Both PVP and BPVP were safe and effective alternatives in men requiring surgery for benign prostatic hyperplasia including patients who were on anticoagulants. Additionally, BPVP has the advantage of being significantly cheaper and therefore it can be more useful in developing countries. PMID- 29593471 TI - Rare Metastatic Testicular Cancer in a Veteran.

PMID- 29593473 TI - Cerebral Cavernous Malformations: An Update on Prevalence, Molecular Genetic Analyses, and Genetic Counselling. AB - Based on the latest gnomAD dataset, the prevalence of symptomatic hereditary cerebral cavernous malformations (CCMs) prone to cause epileptic seizures and stroke-like symptoms was re-evaluated in this review and calculated to be 1:5,400 1:6,200. Furthermore, state-of-the-art molecular genetic analyses of the known CCM loci are described which reach an almost 100% mutation detection rate for familial CCMs if whole genome sequencing is performed for seemingly mutation negative families. An update on the spectrum of CCM1, CCM2, and CCM3 mutations demonstrates that deep-intronic mutations and submicroscopic copy-number neutral genomic rearrangements are rare. Finally, this review points to current guidelines on genetic counselling, neuroimaging, medical as well as neurosurgical treatment and highlights the formation of active patient organizations in various countries. PMID- 29593475 TI - Language and Cognitive Impairment Associated with a Novel p.Cys63Arg Change in the MED13L Transcriptional Regulator. AB - Mutations in the MED13L gene, which encodes a subunit of a transcriptional regulatory complex, result in a complex phenotype entailing physical and cognitive anomalies. Deep language impairment has been reported in affected individuals, mostly in patients with copy number variations. We report on a child with a nonsynonymous p.Cys63Arg change in MED13L (chr12:116675396A>G, GRCh37) who exhibits profound language impairment in the expressive domain, cognitive delay, behavioral disturbances, and an autism-like phenotype. Because of the brain areas in which MED13L is expressed and because of the functional links between MED13L and the products of selected candidate genes for cognitive disorders involving language deficits, the proband's linguistic phenotype may result from changes in a functional network important for language development and evolution. PMID- 29593476 TI - Novel and Recurrent Mutations in the FGFR3 Gene and Double Heterozygosity Cases in a Cohort of Brazilian Patients with Skeletal Dysplasia. AB - Mutations in the fibroblast growth factor receptor 3 gene (FGFR3) cause achondroplasia (ACH), hypochondroplasia (HCH), and thanatophoric dysplasia types I and II (TDI/TDII). In this study, we performed a genetic study of 123 Brazilian patients with these phenotypes. Mutation hotspots of the FGFR3 gene were PCR amplified and sequenced. All cases had recurrent mutations related to ACH, HCH, TDI or TDII, except for 2 patients. One of them had a classical TDI phenotype but a typical ACH mutation (c.1138G>A) in combination with a novel c.1130T>C mutation predicted as being pathogenic. The presence of the second c.1130T>C mutation likely explained the more severe phenotype. Another atypical patient presented with a compound phenotype that resulted from a combination of ACH and X-linked spondyloepiphyseal dysplasia tarda (OMIM 313400). Next-generation sequencing of this patient's DNA showed double heterozygosity for a typical de novo ACH c.1138G>A mutation and a maternally inherited TRAPPC2 c.6del mutation. All mutations were confirmed by Sanger sequencing. A pilot study using high resolution melting (HRM) technique was also performed to confirm several mutations identified through sequencing. We concluded that for recurrent FGFR3 mutations, HRM can be used as a faster, reliable, and less expensive genotyping test than Sanger sequencing. PMID- 29593474 TI - A Clinical Review of Generalized Overgrowth Syndromes in the Era of Massively Parallel Sequencing. AB - The overgrowth syndromes are important to diagnose, not just for accurate genetic counseling, but also for knowledge surrounding cancer surveillance and prognosis. There has been a recent expansion in the number of genes associated with a mendelian overgrowth phenotype, so this review updates previous classifications of overgrowth syndromes. We also describe a clinical and molecular approach to the investigation of individuals presenting with overgrowth. This review aims to assist the clinical diagnosis of generalized overgrowth syndromes by outlining the salient features of well-known overgrowth syndromes alongside the many syndromes that have been discovered and classified more recently. We provide key clinical "handles" to aid clinical diagnosis and a list of genes to aid with panel design when using next generation sequencing, which we believe is frequently needed due to the overlapping phenotypic features seen between overgrowth syndromes. PMID- 29593477 TI - Novel Nonsense Mutation in SLC39A13 Initially Presenting as Myopathy: Case Report and Review of the Literature. AB - Myopathies comprise a heterogeneous group of disorders characterized by variable phenotypes. The increasing use of next-generation sequencing allows identification of the causative genes in a much higher percentage of patients with hereditary muscle disorders and also illustrates a considerable degree of overlap with other clinical entities, including connective tissue disorders. Here, we present a 14-year-old German patient who was initially suspected to suffer from myopathy based on his clinical, radiological, and muscle biopsy findings. Exome sequencing revealed a novel homozygous nonsense mutation in the SLC39A13 gene, causative for spondylocheiro dysplastic Ehlers Danlos syndrome (SCD-EDS), suggesting a connective tissue disorder. Including our patient, only 9 affected individuals from 4 families have been described for SCD-EDS so far. The previously reported patients did not show obvious evidence of myopathy, suggesting a broader clinical presentation than originally suspected. We summarize herein the current knowledge on clinical features as well as pathophysiological pathways for this rare connective tissue disease and discuss the high degree of clinical overlap between myopathic and connective tissue disorders.

AB - The alacrima, achalasia, and mental retardation syndrome (AAMR) is a newly described autosomal recessive disorder characterized by the onset of these 3 main features at birth or in early infancy. At present, only 16 cases have been reported. Recently, it was shown that AAMR is due to mutations in the guanosine diphosphate (GDP)-mannose pyrophosphorylase A (GMPPA) gene. These mutations induce a significant GDP-mannose overload, which may affect protein glycosylation. Herein, for the first time, we describe 2 adult sisters with AAMR with a previously not reported deleterious homozygous missense mutation c.1118G>C (p.Arg373Pro) in the GMPPA gene, born to healthy consanguineous heterozygous parents from an ancient endogamous population. The main symptoms in both sisters started soon after birth with achalasia and feeding difficulties, requiring surgical treatment. Both sisters showed alacrima identified during the first months of life, delayed psychomotor development, speech delay, facial dysmorphism, limb defects, short stature, and moderate intellectual disability. Alacrima and feeding difficulties due to achalasia during the neonatal period or first months of life, in the absence of adrenal cortical insufficiency, should spur to investigate AAMR by sequencing the GMPPA gene. PMID- 29593481 TI - Using Support Vector Machine on EEG for Advertisement Impact Assessment. AB - The advertising industry depends on an effective assessment of the impact of advertising as a key performance metric for their products. However, current assessment methods have relied on either indirect inference from observing changes in consumer behavior after the launch of an advertising campaign, which has long cycle times and requires an ad campaign to have already have been launched (often meaning costs having been sunk). Or through surveys or focus groups, which have a potential for experimental biases, peer pressure, and other psychological and sociological phenomena that can reduce the effectiveness of the study. In this paper, we investigate a new approach to assess the impact of advertisement by utilizing low-cost EEG headbands to record and assess the measurable impact of advertising on the brain. Our evaluation shows the desired performance of our method based on user experiment with 30 recruited subjects after watching 220 different advertisements. We believe the proposed SVM method can be further developed to a general and scalable methodology that can enable advertising agencies to assess impact rapidly, quantitatively, and without bias.

PMID- 29593483 TI - Computing Generalized Matrix Inverse on Spiking Neural Substrate. AB - Emerging neural hardware substrates, such as IBM's TrueNorth Neurosynaptic System, can provide an appealing platform for deploying numerical algorithms. For example, a recurrent Hopfield neural network can be used to find the Moore Penrose generalized inverse of a matrix, thus enabling a broad class of linear optimizations to be solved efficiently, at low energy cost. However, deploying numerical algorithms on hardware platforms that severely limit the range and precision of representation for numeric quantities can be quite challenging. This paper discusses these challenges and proposes a rigorous mathematical framework for reasoning about range and precision on such substrates. The paper derives techniques for normalizing inputs and properly quantizing synaptic weights originating from arbitrary systems of linear equations, so that solvers for those systems can be implemented in a provably correct manner on hardware-constrained neural substrates. The analytical model is empirically validated on the IBM TrueNorth platform, and results show that the guarantees provided by the framework for range and precision hold under experimental conditions. Experiments with optical flow demonstrate the energy benefits of deploying a reduced precision and energy-efficient generalized matrix inverse engine on the IBM TrueNorth platform, reflecting 10* to 100* improvement over FPGA and ARM core baselines. PMID- 29593484 TI - Neurogenomic Profiling Reveals Distinct Gene Expression Profiles Between Brain Parts That Are Consistent in Ophthalmotilapia Cichlids. AB - The detection of external and internal cues alters gene expression in the brain which in turn may affect neural networks that underly behavioral responses. Previous studies have shown that gene expression profiles differ between major brain regions within individuals and between species with different morphologies, cognitive abilities and/or behaviors. A detailed description of gene expression in all macroanatomical brain regions and in species with similar morphologies and behaviors is however lacking. Here, we dissected the brain of two cichlid species into six macroanatomical regions. Ophthalmotilapia nasuta and O. ventralis have similar morphology and behavior and occasionally hybridize in the wild. We use 3' mRNA sequencing and a stage-wise statistical testing procedure to identify differential gene expression between females that were kept in a social setting with other females. Our results show that gene expression differs substantially between all six brain parts within species: out of 11,577 assessed genes, 8,748 are differentially expressed (DE) in at least one brain part compared to the average expression of the other brain parts. At most 16% of these DE genes have |log2FC| significantly higher than two. Functional differences between brain parts were consistent between species. The majority (61-79%) of genes that are DE in a particular brain part were shared between both species. Only 32 genes show significant differences in fold change across brain parts between species. These genes are mainly linked to transport, transmembrane transport, transcription (and its regulation) and signal transduction. Moreover, statistical equivalence testing reveals that within each comparison, on average 89% of the genes show an equivalent fold change between both species. The pronounced differences in gene expression between brain parts and the conserved patterns between closely related species with similar morphologies and behavior suggest that unraveling the interactions between genes and behavior will benefit from neurogenomic profiling of distinct brain regions.

AB - If the scalp potential signals, the electroencephalogram (EEG), are due to neural "singers" in the brain, how could we listen to them with less distortion? One crucial point is that the data recording on the scalp should be faithful and accurate, thus the choice of reference electrode is a vital factor determining the faithfulness of the data. In this study, music on the scalp derived from data in the brain using three different reference electrodes were compared, including approximate zero reference-reference electrode standardization technique (REST), average reference (AR), and linked mastoids reference (LM). The classic music pieces in waveform format were used as simulated sources inside a head model, and they were forward calculated to scalp as standard potential recordings, i.e., waveform format music from the brain with true zero reference. Then these scalp music was re-referenced into REST, AR, and LM based data, and compared with the original forward data (true zero reference). For real data, the EEG recorded in an orthodontic pain control experiment were utilized for music generation with the three references, and the scale free index (SFI) of these music pieces were compared. The results showed that in the simulation for only one source, different references do not change the music/waveform; for two sources or more, REST provide the most faithful music/waveform to the original ones inside the brain, and the distortions caused by AR and LM were spatial locations of both source and scalp electrode dependent. The brainwave music from the real EEG data showed that REST and AR make the differences of SFI between two states more recognized and found the frontal is the main region that producing the music. In conclusion, REST can reconstruct the true signals approximately, and it can be used to help to listen to the true voice of the neural singers in the brain. PMID- 29593485 TI - "Till Death Do Us Part": A Potential Irreversible Link Between Aberrant Cell Cycle Control and Neurodegeneration in the Adult Olfactory Bulb. AB - Adult neurogenesis (AN) is an ongoing developmental process that generates newborn neurons in the olfactory bulb (OB) and the hippocampus (Hi) throughout life and significantly contributes to brain plasticity. Adult neural stem and progenitor cells (aNSPCs) are relatively limited in number and fate and are spatially restricted to the subventricular zone (SVZ) and the subgranular zone (SGZ). During AN, the distinct roles played by cell cycle proteins extend beyond cell cycle control and constitute key regulatory mechanisms involved in neuronal maturation and survival. Importantly, aberrant cell cycle re-entry (CCE) in post mitotic neurons has been strongly linked to the abnormal pathophysiology in rodent models of neurodegenerative diseases with potential implications on the etiology and progression of such diseases in humans. Here, we present an overview of AN in the SVZ-OB and olfactory epithelium (OE) in mice and humans followed by a comprehensive update of the distinct roles played by cell cycle proteins including major tumors suppressor genes in various steps during neurogenesis. We also discuss accumulating evidence underlining a strong link between abnormal cell cycle control, olfactory dysfunction and neurodegeneration in the adult and aging brain. We emphasize that: (1) CCE in post-mitotic neurons due to loss of cell cycle suppression and/or age-related insults as well as DNA damage can anticipate the development of neurodegenerative lesions and protein aggregates, (2) the age-related decline in SVZ and OE neurogenesis is associated with compensatory pro-survival mechanisms in the aging OB which are interestingly similar to those detected in Alzheimer's disease and Parkinson's disease in humans, and (3) the OB represents a well suitable model to study the early manifestation of age-related defects that may eventually progress into the formation of neurodegenerative lesions and, possibly, spread to the rest of the brain. Such findings may provide a novel approach to the modeling of neurodegenerative diseases in humans from early detection to progression and treatment as well. PMID- 29593488 TI - A Set of Functional Brain Networks for the Comprehensive Evaluation of Human Characteristics. AB - Many human characteristics must be evaluated to comprehensively understand an individual, and measurements of the corresponding cognition/behavior are required. Brain imaging by functional MRI (fMRI) has been widely used to examine brain function related to human cognition/behavior. However, few aspects of cognition/behavior of individuals or experimental groups can be examined through task-based fMRI. Recently, resting state fMRI (rs-fMRI) signals have been shown to represent functional infrastructure in the brain that is highly involved in processing information related to cognition/behavior. Using rs-fMRI may allow diverse information about the brain through a single MRI scan to be obtained, as rs-fMRI does not require stimulus tasks. In this study, we attempted to identify a set of functional networks representing cognition/behavior that are related to a wide variety of human characteristics and to evaluate these characteristics using rs-fMRI data. If possible, these findings would support the potential of rs fMRI to provide diverse information about the brain. We used resting-state fMRI and a set of 130 psychometric parameters that cover most human characteristics, including those related to intelligence and emotional quotients and social ability/skill. We identified 163 brain regions by VBM analysis using regression analysis with 130 psychometric parameters. Next, using a 163 * 163 correlation matrix, we identified functional networks related to 111 of the 130 psychometric parameters. Finally, we made an 8-class support vector machine classifiers corresponding to these 111 functional networks. Our results demonstrate that rs fMRI signals contain intrinsic information about brain function related to cognition/behaviors and that this set of 111 networks/classifiers can be used to comprehensively evaluate human characteristics. PMID- 29593489 TI - Listening Effort During Sentence Processing Is Increased for Non-native Listeners: A Pupillometry Study. AB - Current evidence demonstrates that even though some non-native listeners can achieve native-like performance for speech perception tasks in quiet, the presence of a background noise is much more detrimental to speech intelligibility for non-native compared to native listeners. Even when performance is equated across groups, it is likely that greater listening effort is required for non native listeners. Importantly, the added listening effort might result in increased fatigue and a reduced ability to successfully perform multiple tasks simultaneously. Task-evoked pupil responses have been demonstrated to be a reliable measure of cognitive effort and can be useful in clarifying those aspects. In this study we compared the pupil response for 23 native English speakers and 27 Italian speakers of English as a second language. Speech intelligibility was tested for sentences presented in quiet and in background noise at two performance levels that were matched across groups. Signal-to-noise levels corresponding to these sentence intelligibility levels were pre-determined using an adaptive intelligibility task. Pupil response was significantly greater in non-native compared to native participants across both intelligibility levels. Therefore, for a given intelligibility level, a greater listening effort is required when listening in a second language in order to understand speech in noise. Results also confirmed that pupil response is sensitive to speech intelligibility during language comprehension, in line with previous research. However, contrary to our predictions, pupil response was not differentially modulated by intelligibility levels for native and non-native listeners. The present study corroborates that pupillometry can be deemed as a valid measure to be used in speech perception investigation, because it is sensitive to differences both across participants, such as listener type, and across conditions, such as variations in the level of speech intelligibility. Importantly, pupillometry offers us the possibility to uncover differences in listening effort even when those do not emerge in the performance level of individuals. PMID- 29593490 TI - A Comparative Study of Standardized Infinity Reference and Average Reference for EEG of Three Typical Brain States. AB - The choice of different reference electrodes plays an important role in deciphering the functional meaning of electroencephalography (EEG) signals. In recent years, the infinity zero reference using the reference electrode standard technique (REST) has been increasingly applied, while the average reference (AR) was generally advocated as the best available reference option in previous classical EEG studies. Here, we designed EEG experiments and performed a direct comparison between the influences of REST and AR on EEG-revealed brain activity features for three typical brain behavior states (eyes-closed, eyes-open and music-listening). The analysis results revealed the following observations: (1) there is no significant difference in the alpha-wave-blocking effect during the eyes-open state compared with the eyes-closed state for both REST and AR references; (2) there was clear frontal EEG asymmetry during the resting state, and the degree of lateralization under REST was higher than that under AR; (3) the global brain functional connectivity density (FCD) and local FCD have higher values for REST than for AR under different behavior states; and (4) the value of the small-world network characteristic in the eyes-closed state is significantly (in full, alpha, beta and gamma frequency bands) higher than that in the eyes open state, and the small-world effect under the REST reference is higher than that under AR. In addition, the music-listening state has a higher small-world network effect than the eyes-closed state. The above results suggest that typical EEG features might be more clearly presented by applying the REST reference than by applying AR when using a 64-channel recording. PMID- 29593491 TI - Can Interactions Between alpha-Synuclein, Dopamine and Calcium Explain Selective Neurodegeneration in Parkinson's Disease? AB - Several lines of evidence place alpha-synuclein (aSyn) at the center of Parkinson's disease (PD) etiology, but it is still unclear why overexpression or mutated forms of this protein affect some neuronal populations more than others. Susceptible neuronal populations in PD, dopaminergic neurons of the substantia nigra pars compacta (SNpc) and the locus coeruleus (LC), are distinguished by relatively high cytoplasmic concentrations of dopamine and calcium ions. Here we review the evidence for the multi-hit hypothesis of neurodegeneration, including recent papers that demonstrate synergistic interactions between aSyn, calcium ions and dopamine that may lead to imbalanced protein turnover and selective susceptibility of these neurons. We conclude that decreasing the levels of any one of these toxicity mediators can be beneficial for the survival of SNpc and LC neurons, providing multiple opportunities for targeted drug interventions aimed at modifying the course of PD. PMID- 29593492 TI - Enteroviral Infection: The Forgotten Link to Amyotrophic Lateral Sclerosis? AB - Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease that primarily attacks motor neurons in the brain and spinal cord, leading to progressive paralysis and ultimately death. Currently there is no effective therapy. The majority of ALS cases are sporadic, with no known family history; unfortunately the etiology remains largely unknown. Contribution of Enteroviruses (EVs), a family of positive-stranded RNA viruses including poliovirus, coxsackievirus, echovirus, enterovirus-A71 and enterovirus-D68, to the development of ALS has been suspected as they can target motor neurons, and patients with prior poliomyelitis show a higher risk of motor neuron disease. Multiple efforts have been made to detect enteroviral genome in ALS patient tissues over the past two decades; however the clinical data are controversial and a causal relationship has not yet been established. Recent evidence from in vitro and animal studies suggests that enterovirus-induced pathology remarkably resembles the cellular and molecular phenotype of ALS, indicating a possible link between enteroviral infection and ALS pathogenesis. In this review, we summarize the nature of enteroviral infection, including route of infection, cells targeted, and viral persistence within the central nervous system (CNS). We review the molecular mechanisms underlying viral infection and highlight the similarity between viral pathogenesis and the molecular and pathological features of ALS, and finally, discuss the potential role of enteroviral infection in frontotemporal dementia (FTD), a disease that shares common clinical, genetic, and pathological features with ALS, and the significance of anti-viral therapy as an option for the treatment of ALS.

AB - Rodent models of both aging and obesity are characterized by inflammation in specific brain regions, notably the corpus callosum, fornix, and hypothalamus. Microglia, the resident macrophages of the central nervous system, are important for brain development, neural support, and homeostasis. However, the effects of diet and lifestyle on microglia during aging are only partly understood. Here, we report alterations in microglia phenotype and functions in different brain regions of mice on a high-fat diet (HFD) or low-fat diet (LFD) during aging and in response to voluntary running wheel exercise. We compared the expression levels of genes involved in immune response, phagocytosis, and metabolism in the hypothalamus of 6-month-old HFD and LFD mice. We also compared the immune response of microglia from HFD or LFD mice to peripheral inflammation induced by intraperitoneal injection of lipopolysaccharide (LPS). Finally, we investigated the effect of diet, physical exercise, and caloric restriction (40% reduction compared to ad libitum intake) on microglia in 24-month-old HFD and LFD mice. Changes in diet caused morphological changes in microglia, but did not change the microglia response to LPS-induced systemic inflammation. Expression of phagocytic markers (i.e., Mac-2/Lgals3, Dectin-1/Clec7a, and CD16/CD32) in the white matter microglia of 24-month-old brain was markedly decreased in calorically restricted LFD mice. In conclusion, LFD resulted in reduced activation of microglia, which might be an underlying mechanism for the protective role of caloric restriction during aging-associated decline. PMID- 29593494 TI - Antiepileptogenic Effect of Subchronic Palmitoylethanolamide Treatment in a Mouse Model of Acute Epilepsy. AB - Research on the antiepileptic effects of (endo-)cannabinoids has remarkably progressed in the years following the discovery of fundamental role of the endocannabinoid (eCB) system in controlling neural excitability. Moreover, an increasing number of well-documented cases of epilepsy patients exhibiting multi drug resistance report beneficial effects of cannabis use. Pre-clinical and clinical research has increasingly focused on the antiepileptic effectiveness of exogenous administration of cannabinoids and/or pharmacologically induced increase of eCBs such as anandamide (also known as arachidonoylethanolamide [AEA]). Concomitant research has uncovered the contribution of neuroinflammatory processes and peripheral immunity to the onset and progression of epilepsy. Accordingly, modulation of inflammatory pathways such as cyclooxygenase-2 (COX-2) was pursued as alternative therapeutic strategy for epilepsy. Palmitoylethanolamide (PEA) is an endogenous fatty acid amide related to the centrally and peripherally present eCB AEA, and is a naturally occurring nutrient that has long been recognized for its analgesic and anti-inflammatory properties. Neuroprotective and anti-hyperalgesic properties of PEA were evidenced in neurodegenerative diseases, and antiepileptic effects in pentylenetetrazol (PTZ), maximal electroshock (MES) and amygdaloid kindling models of epileptic seizures. Moreover, numerous clinical trials in chronic pain revealed that PEA treatment is devoid of addiction potential, dose limiting side effects and psychoactive effects, rendering PEA an appealing candidate as antiepileptic compound or adjuvant. In the present study, we aimed at assessing antiepileptic properties of PEA in a mouse model of acute epileptic seizures induced by systemic administration of kainic acid (KA). KA-induced epilepsy in rodents is assumed to resemble to different extents human temporal lobe epilepsy (TLE) depending on the route of KA administration; intracerebral (i.c.) injection was recently shown to most closely mimic human TLE, while systemic KA administration causes more widespread pathological damage, both in brain and periphery. To explore the potential of PEA to exert therapeutic effects both in brain and periphery, acute and subchronic administration of PEA by intraperitoneal (i.p.) injection was assessed on mice with systemically administered KA. Specifically, we investigated: (i) neuroprotective and anticonvulsant properties of acute and subchronic PEA treatment in KA-induced seizure models, and (ii) temporal dynamics of eCB and eicosanoid (eiC) levels in hippocampus and plasma over 180 min post seizure induction in PEA-treated and non-treated KA-injected mice vs. vehicle injected mice. Finally, we compared the systemic PEA treatment with, and in combination with, pharmacological blockade of fatty acid amide hydrolase (FAAH) in brain and periphery, in terms of anticonvulsant properties and modulation of eCBs and eiCs. Here, we demonstrate that subchronic administration of PEA significantly alleviates seizure intensity, promotes neuroprotection and induces modulation of the plasma and hippocampal eCB and eiC levels in systemic KA injected mice. PMID- 29593495 TI - Mitochondrial Molecular Abnormalities Revealed by Proteomic Analysis of Hippocampal Organelles of Mice Triple Transgenic for Alzheimer Disease. AB - Mitochondrial dysfunction is implicated in the pathogenesis of Alzheimer's disease (AD). However, the precise mitochondrial molecular deficits in AD remain poorly understood. Mitochondrial and nuclear proteomic analysis in mature male triple transgenic AD mice (PS1M146V/APPSwe/TauP301L) by two-dimensional fluorescence difference gel electrophoresis (2D-DIGE) coupled with MALDI-TOF MS/MS, bio-informatics analysis and immunofluorescent staining were performed in this study. In addition to impaired spatial memory impairment and intracellular accumulation of amyloid 1-42 (Abeta1-42) in the 3xTg-AD mice, a well-accepted mouse model of the human disease, we also found significantly increased DNA oxidative damage in entorhinal cortex, hippocampal CA1, CA3 and dental gyrus (DG), as evidenced by the positive staining of 8-hydroxyguanosine, a biomarker of mild cognitive impairment early in AD. We identified significant differences in 27 hippocampal mitochondrial proteins (11 increased and 16 decreased), and 37 hippocampal nuclear proteins (12 increased and 25 decreased) in 3xTg-AD mice compared with the wild-type (WT) mice. Differentially expressed mitochondrial and nuclear proteins were mainly involved in energy metabolism (>55%), synapses, DNA damage, apoptosis and oxidative stress. Two proteins were differentially expressed in both hippocampal mitochondria and nuclei, namely electron transport chain (ETC)-related protein ATP synthase subunit d (ATP5H) was significantly decreased, and apoptosis-related dynamin-1 (DYN1), a pre-synaptic and mitochondrial division-regulated protein that was significantly increased. In sum, perturbations of hippocampus mitochondrial energy metabolism-related proteins responsible for ATP generation via oxidation phosphorylation (OXPHOS), especially nuclear-encoded OXPHOS proteins, correlated with the amyloid associated cognitive deficits of this murine AD model. The molecular changes in respiratory chain-related proteins and DYN1 may represent novel biomarkers of AD. PMID- 29593496 TI - Q-Rich Yeast Prion [PSI+] Accelerates Aggregation of Transthyretin, a Non-Q-Rich Human Protein. AB - Interactions amongst different amyloid proteins have been proposed as a probable mechanism of aggregation and thus an important risk factor for the onset as well as progression of various neurodegenerative disorders including Alzheimer's, Parkinson's, Huntington's, and Amyotrophic Lateral Sclerosis. Evidences suggest that transthyretin (TTR), a plasma protein associated with transthyretin amyloidosis or familial polyneuropathy (FAP) interacts with heterologous amyloid proteins including amyloid beta and islet amyloid polypeptide. In addition, recent clinical studies have revealed the presence of systemic polyneuropathy associated with FAP mutations in patients with spinocerebral ataxia, amyotrophic lateral sclerosis, and new familial systematic prion disease. Hence, it is important to investigate the interactions amongst different amyloid proteins to gain better insight into the pathology of amyloid disorders. Yeast has been an excellent model system to study interaction/ cross-seeding between heterologous amyloid proteins, more because of presence of endogenous yeast prions. Here, we examined interactions of non-glutamine (non-Q)-rich transthyretin, with glutamine (Q)-rich yeast prion protein Sup35. We established aggregation of an engineered double (F87M/L110M) mutant M-TTR-GFP in yeast. This mutant is monomeric and readily formed aggregates compared to WT-TTR-GFP in yeast at acidic pH. Interestingly, aggregation of M-TTR-GFP was significantly enhanced in presence of [PSI+], an endogenous prion form of Sup35. Different variants of [PSI+] seeded M TTR-GFP with different efficiencies and curing of [PSI+] (losing the prion form) in these strains reduced aggregation. Moreover, overexpression of prion domain of Sup35 fused to RFP (NM-RFP) also increased M-TTR-GFP aggregation. M-TTR-GFP and NM-RFP aggregates co-localized in perivacuolar and juxtranuclear region. Sup35 protein was even immunocaptured in M-TTR-GFP aggregates. However, M-TTR-GFP overexpression did not induce Sup35 aggregation. Thus, it appears to be a unidirectional interaction between these two amyloid proteins. However, no affect on M-TTR-GFP aggregation was observed due to another yeast prion, [PIN+]. Our findings thus show the molecular interaction of transthyretin with yeast prion and support that sequence similarity is not the prime requirement for heterologous amyloid interactions. PMID- 29593497 TI - Reprogramming Glia Into Neurons in the Peripheral Auditory System as a Solution for Sensorineural Hearing Loss: Lessons From the Central Nervous System. AB - Disabling hearing loss affects over 5% of the world's population and impacts the lives of individuals from all age groups. Within the next three decades, the worldwide incidence of hearing impairment is expected to double. Since a leading cause of hearing loss is the degeneration of primary auditory neurons (PANs), the sensory neurons of the auditory system that receive input from mechanosensory hair cells in the cochlea, it may be possible to restore hearing by regenerating PANs. A direct reprogramming approach can be used to convert the resident spiral ganglion glial cells into induced neurons to restore hearing. This review summarizes recent advances in reprogramming glia in the CNS to suggest future steps for regenerating the peripheral auditory system. In the coming years, direct reprogramming of spiral ganglion glial cells has the potential to become one of the leading biological strategies to treat hearing impairment. PMID- 29593498 TI - Reactive Neuroblastosis in Huntington's Disease: A Putative Therapeutic Target for Striatal Regeneration in the Adult Brain. AB - The cellular and molecular mechanisms underlying the reciprocal relationship between adult neurogenesis, cognitive and motor functions have been an important focus of investigation in the establishment of effective neural replacement therapies for neurodegenerative disorders. While neuronal loss, reactive gliosis and defects in the self-repair capacity have extensively been characterized in neurodegenerative disorders, the transient excess production of neuroblasts detected in the adult striatum of animal models of Huntington's disease (HD) and in post-mortem brain of HD patients, has only marginally been addressed. This abnormal cellular response in the striatum appears to originate from the selective proliferation and ectopic migration of neuroblasts derived from the subventricular zone (SVZ). Based on and in line with the term "reactive astrogliosis", we propose to name the observed cellular event "reactive neuroblastosis". Although, the functional relevance of reactive neuroblastosis is unknown, we speculate that this process may provide support for the tissue regeneration in compensating the structural and physiological functions of the striatum in lieu of aging or of the neurodegenerative process. Thus, in this review article, we comprehend different possibilities for the regulation of striatal neurogenesis, neuroblastosis and their functional relevance in the context of HD. PMID- 29593499 TI - Mob2 Insufficiency Disrupts Neuronal Migration in the Developing Cortex. AB - Disorders of neuronal mispositioning during brain development are phenotypically heterogeneous and their genetic causes remain largely unknown. Here, we report biallelic variants in a Hippo signaling factor-MOB2-in a patient with one such disorder, periventricular nodular heterotopia (PH). Genetic and cellular analysis of both variants confirmed them to be loss-of-function with enhanced sensitivity to transcript degradation via nonsense mediated decay (NMD) or increased protein turnover via the proteasome. Knockdown of Mob2 within the developing mouse cortex demonstrated its role in neuronal positioning. Cilia positioning and number within migrating neurons was also impaired with comparable defects detected following a reduction in levels of an upstream modulator of Mob2 function, Dchs1, a previously identified locus associated with PH. Moreover, reduced Mob2 expression increased phosphorylation of Filamin A, an actin cross-linking protein frequently mutated in cases of this disorder. These results reveal a key role for Mob2 in correct neuronal positioning within the developing cortex and outline a new candidate locus for PH development. PMID- 29593501 TI - Chronic Stress Reduces Nectin-1 mRNA Levels and Disrupts Dendritic Spine Plasticity in the Adult Mouse Perirhinal Cortex. AB - In adulthood, chronic exposure to stressful experiences disrupts synaptic plasticity and cognitive function. Previous studies have shown that perirhinal cortex-dependent object recognition memory is impaired by chronic stress. However, the stress effects on molecular expression and structural plasticity in the perirhinal cortex remain unclear. In this study, we applied the chronic social defeat stress (CSDS) paradigm and measured the mRNA levels of nectin-1, nectin-3 and neurexin-1, three synaptic cell adhesion molecules (CAMs) implicated in the adverse stress effects, in the perirhinal cortex of wild-type (WT) and conditional forebrain corticotropin-releasing hormone receptor 1 conditional knockout (CRHR1-CKO) mice. Chronic stress reduced perirhinal nectin-1 mRNA levels in WT but not CRHR1-CKO mice. In conditional forebrain corticotropin-releasing hormone conditional overexpression (CRH-COE) mice, perirhinal nectin-1 mRNA levels were also reduced, indicating that chronic stress modulates nectin-1 expression through the CRH-CRHR1 system. Moreover, chronic stress altered dendritic spine morphology in the main apical dendrites and reduced spine density in the oblique apical dendrites of perirhinal layer V pyramidal neurons. Our data suggest that chronic stress disrupts cell adhesion and dendritic spine plasticity in perirhinal neurons, which may contribute to stress-induced impairments of perirhinal cortex-dependent memory. PMID- 29593502 TI - The Spinal Neurons Exhibit an ON-OFF and OFF-ON Firing Activity Around the Onset of Fictive Scratching Episodes in the Cat. AB - In a previous report, we found neurons with ON-OFF and OFF-ON firing activity in the obex reticular formation during scratching. The aim of the present study was to examine whether the spinal neurons also exhibit this type of activity in relation to the "postural stage" of fictive scratching in the cat. We found that the extensor and intermediate scratching neurons exhibit an ON-OFF firing rate; conversely, the flexor neurons show an OFF-ON activity, relative to every scratching episode. These patterns of spiking activity are similar to those found in neurons from the obex reticular formation during scratching. Our findings provide support to the following hypotheses. First, there is a possible functional link between supraspinal and spinal, ON-OFF and OFF-ON neuronal groups. Second, the fictive goal-directed motor action to maintain the fictive "postural stage" of the hindlimb during fictive scratching is associated with the neuronal tonic activity of the OFF-ON spinal neurons, whereas the ON-OFF spinal neurons are associated with an extensor tone that occurred prior the postural stage. PMID- 29593500 TI - Sensing Exocytosis and Triggering Endocytosis at Synapses: Synaptic Vesicle Exocytosis-Endocytosis Coupling. AB - The intact synaptic structure is critical for information processing in neural circuits. During synaptic transmission, rapid vesicle exocytosis increases the size of never terminals and endocytosis counteracts the increase. Accumulating evidence suggests that SV exocytosis and endocytosis are tightly connected in time and space during SV recycling, and this process is essential for synaptic function and structural stability. Research in the past has illustrated the molecular details of synaptic vesicle (SV) exocytosis and endocytosis; however, the mechanisms that timely connect these two fundamental events are poorly understood at central synapses. Here we discuss recent progress in SV recycling and summarize several emerging mechanisms by which synapses can "sense" the occurrence of exocytosis and timely initiate compensatory endocytosis. They include Ca2+ sensing, SV proteins sensing, and local membrane stress sensing. In addition, the spatial organization of endocytic zones adjacent to active zones provides a structural basis for efficient coupling between SV exocytosis and endocytosis. Through linking different endocytosis pathways with SV fusion, these mechanisms ensure necessary plasticity and robustness of nerve terminals to meet diverse physiological needs. PMID- 29593503 TI - Emergence of Serotonergic Neurons After Spinal Cord Injury in Turtles. AB - Plasticity of neural circuits takes many forms and plays a fundamental role in regulating behavior to changing demands while maintaining stability. For example, during spinal cord development neurotransmitter identity in neurons is dynamically adjusted in response to changes in the activity of spinal networks. It is reasonable to speculate that this type of plasticity might occur also in mature spinal circuits in response to injury. Because serotonergic signaling has a central role in spinal cord functions, we hypothesized that spinal cord injury (SCI) in the fresh water turtle Trachemys scripta elegans may trigger homeostatic changes in serotonergic innervation. To test this possibility we performed immunohistochemistry for serotonin (5-HT) and key molecules involved in the determination of the serotonergic phenotype before and after SCI. We found that as expected, in the acute phase after injury the dense serotonergic innervation was strongly reduced. However, 30 days after SCI the population of serotonergic cells (5-HT+) increased in segments caudal to the lesion site. These cells expressed the neuronal marker HuC/D and the transcription factor Nkx6.1. The new serotonergic neurons did not incorporate the thymidine analog 5-bromo-2' deoxyuridine (BrdU) and did not express the proliferating cell nuclear antigen (PCNA) indicating that novel serotonergic neurons were not newborn but post mitotic cells that have changed their neurochemical identity. Switching towards a serotonergic neurotransmitter phenotype may be a spinal cord homeostatic mechanism to compensate for the loss of descending serotonergic neuromodulation, thereby helping the outstanding functional recovery displayed by turtles. The 5 HT1A receptor agonist (+/-)-8-Hydroxy-2-dipropylaminotetralin hydrobromide (8-OH DPAT) blocked the increase in 5-HT+ cells suggesting 5-HT1A receptors may trigger the respecification process. PMID- 29593504 TI - Neuromodulatory Correlates of Pupil Dilation. AB - Pupillometry has long been used as a measure of brain state. Changes in pupil diameter are thought to coincide with the activity of neuromodulators, including noradrenaline and acetylcholine, producing alterations in the brain state and corresponding changes in behavior. Here we review mechanisms underlying the control of pupil diameter and how these mechanisms are correlated with changes in cortical activity and the recruitment of neuromodulatory circuits. PMID- 29593505 TI - The Shark Basal Hypothalamus: Molecular Prosomeric Subdivisions and Evolutionary Trends. AB - The hypothalamus is a key integrative center of the vertebrate brain. To better understand its ancestral morphological organization and evolution, we previously analyzed the segmental organization of alar subdivisions in the catshark Scyliorhinus canicula, a cartilaginous fish and thus a basal representative of gnathostomes (jawed vertebrates). With the same aim, we deepen here in the segmental organization of the catshark basal hypothalamus by revisiting previous data on ScOtp, ScDlx2/5, ScNkx2.1, ScShh expression and Shh immunoreactivity jointly with new data on ScLhx5, ScEmx2, ScLmx1b, ScPitx2, ScPitx3a, ScFoxa1, ScFoxa2 and ScNeurog2 expression and proliferating cell nuclear antigen (PCNA) immunoreactivity. Our study reveals a complex genoarchitecture for chondrichthyan basal hypothalamus on which a total of 21 microdomains were identified. Six belong to the basal acroterminal region, the rostral-most point of the basal neural tube; seven are described in the tuberal region (Tu/RTu); four in the perimamillar region (PM/PRM) and four in the mamillar one (MM/RM). Interestingly, the same set of genes does not necessarily describe the same microdomains in mice, which in part contributes to explain how forebrain diversity is achieved. This study stresses the importance of analyzing data from basal vertebrates to better understand forebrain diversity and hypothalamic evolution. PMID- 29593507 TI - The Times of Our Lives: Interaction Among Different Biological Periodicities. AB - Environmental cycles on Earth display different periodicities, including daily, tidal or annual time scales. Virtually all living organisms have developed temporal mechanisms to adapt to such changes in environmental conditions. These biological timing structures-ranging from microsecond to seasonal timing-may have intrinsic properties and even different clock machinery. However, interaction among these temporal systems may present evolutionary advantages, for example, when species are exposed to changing climatic conditions or different geographic locations. Here, we present and discuss a model that accounts for the circadian regulation of both ultradian (less than 24-h) and infradian (more than 24-h) cycles and for the interaction among the three time scales. We show two clear examples of such interaction: (i) between the circadian clock and the seasonal regulation of the Hypothalamic-Pituitary-Thyroid (HPT) axis; and (ii) between the circadian clock and the hypothalamic-nigrostriatal (HNS) ultradian modulation. This remarkable interplay among the otherwise considered isolated rhythms has been demonstrated to exist in diverse organisms, suggesting an adaptive advantage of multiple scales of biological timing. PMID- 29593506 TI - The Interaction of Pre-programmed Eye Movements With the Vestibulo-Ocular Reflex. AB - The Vestibulo-Ocular Reflex (VOR) works to stabilize gaze during unexpected head movements. However, even subjects who lack a VOR (e.g., vestibulopathic patients) can achieve gaze stability during planned head movements by using pre-programmed eye movements (PPEM). The extent to which PPEM are used by healthy intact subjects and how they interact with the VOR is still unclear. We propose a model of gaze stabilization which makes several claims: (1) the VOR provides ocular stability during unexpected (i.e., passive) head movements; (2) PPEM are used by both healthy and vestibulopathic subjects during planned (i.e., active) head movements; and (3) when a passive perturbation interrupts an active head movement in intact animals (i.e., combined passive and active head movement) the VOR works with PPEM to provide compensation. First, we show how our model can reconcile some seemingly conflicting findings in earlier literature. We then test the above mentioned predictions against data we collected from both healthy and vestibular lesioned guinea pigs. We found that (1) vestibular-lesioned animals showed a dramatic decrease in compensatory eye movements during passive head movements, (2) both populations showed improved ocular compensation during active vs. passive head movements, and (3) during combined active and passive head movements, eye movements compensated for both the active and passive component of head velocity. These results support our hypothesis that while the VOR provides compensation during passive head movements, PPEM are used by both intact and lesioned subjects during active movements and further, that PPEM work together with the VOR to achieve gaze stability. PMID- 29593508 TI - GABAergic Control of Nigrostriatal and Mesolimbic Dopamine in the Rat Brain. AB - Purpose: The present study assessed the effects of the GABAA receptor (R) agonist muscimol (MUS), and the GABAAR antagonist bicuculline (BIC) on neocortical and subcortical radioligand binding to dopamine D2/3Rs in relation to motor and exploratory behaviors in the rat. Methods: D2/3R binding was measured with small animal SPECT in baseline and after challenge with either 1 mg/kg MUS or 1 mg/kg BIC, using [123I]IBZM as radioligand. Motor/exploratory behaviors were assessed for 30 min in an open field prior to radioligand administration. Anatomical information was gained with a dedicated small animal MRI tomograph. Based on the Paxinos rat brain atlas, regions of interest were defined on SPECT-MRI overlays. Estimations of the binding potentials in baseline and after challenges were obtained by computing ratios of the specifically bound compartments to the cerebellar reference region. Results: After MUS, D2/3R binding was significantly reduced in caudateputamen, nucleus accumbens, thalamus, substania nigra/ventral tegmental area, and posterior hippocampus relative to baseline (0.005 <= p <= 0.012). In all these areas, except for the thalamus, D2/3R binding was negatively correlated with grooming in the first half and positively correlated with various motor/exploratory behaviors in the second half of the testing session. After BIC, D2/3R binding was significantly elevated in caudateputamen (p = 0.022) and thalamus (p = 0.047) relative to baseline. D2/3R binding in caudateputamen and thalamus was correlated negatively with sitting duration and sitting frequency and positively with motor/exploratory behaviors in the first half of the testing time. Conclusions: Findings indicate direct GABAergic control over nigrostriatal and mesolimbic dopamine levels in relation to behavioral action. This may be of relevance for neuropsychiatric conditions such as anxiety disorder and schizophrenia, which are characterized by both dopaminergic and GABAergic dysfunction. PMID- 29593509 TI - Tantrums, Emotion Reactions and Their EEG Correlates in Childhood Benign Rolandic Epilepsy vs. Complex Partial Seizures: Exploratory Observations. AB - We explored associations between EEG pathophysiology and emotional/behavioral (E/B) problems of children with two types of epilepsy using standard parent questionnaires and two new indicators: tantrums recorded by parents at home and brief, emotion-eliciting situations in the laboratory. Children with Benign Rolandic epilepsy (BRE, N = 6) reportedly had shorter, more angry tantrums from which they recovered quickly. Children with Complex Partial Seizures (CPS, N = 13) had longer, sadder tantrums often followed by bad moods. More generally, BRE correlated with anger and aggression; CPS with sadness and withdrawal. Scores of a composite group of siblings (N = 11) were generally intermediate between the BRE and CPS groups. Across all children, high voltage theta and/or interictal epileptiform discharges (IEDs) correlated with negative emotional reactions. Such EEG abnormalities in left hemisphere correlated with greater social fear, right hemisphere EEG abnormalities with greater anger. Right hemisphere localization in CPS was also associated with parent-reported problems at home. If epilepsy alters neural circuitry thereby increasing negative emotions, additional assessment of anti-epileptic drug treatment of epilepsy-related E/B problems would be warranted. PMID- 29593510 TI - Chronic Stress Alters Behavior in the Forced Swim Test and Underlying Neural Activity in Animals Exposed to Alcohol Prenatally: Sex- and Time-Dependent Effects. AB - Dysregulation of the hypothalamic-pituitary-adrenal (HPA) stress response has been suggested to play a role in vulnerability to stress-related disorders, such as depression. Prenatal alcohol exposure (PAE) may result in HPA dysregulation, which in turn may predispose individuals to the effects of stress exposure throughout life, and increase their risk of developing depression compared to unexposed individuals. We examined the immediate and delayed effects of chronic unpredictable stress (CUS) in adulthood on behavior of PAE animals in the forced swim test (FST) and the neurocircuitry underlying behavioral, emotional, and stress regulation. Adult male and female offspring from PAE and control conditions were tested for 2 days in the FST, with testing initiated either 1 day (CUS-1; immediate) or 14 days (CUS-14; delayed) post-CUS. Following testing, c fos mRNA expression of the medial prefrontal cortex (mPFC), amygdala, hippocampal formation, and the paraventricular nucleus of the hypothalamus was assessed. Our results indicate that PAE and CUS interact to differentially alter FST behaviors and neural activation of several brain areas in males and females, and effects may depend on whether testing is immediate or delayed post-CUS. PAE males showed decreased time immobile (Day 1 of FST) following immediate testing, while PAE females showed increased time immobile (Day 2 of FST) following delayed testing compared to their respective control counterparts. Moreover, in males, PAE decreased c-fos mRNA expression in the lateral and central nuclei of the amygdala in the non-CUS condition, and increased c-fos mRNA expression in the CA1 in the CUS-14 condition. By contrast in females, c-fos mRNA expression in the Cg1 was decreased in PAE animals (independent of CUS) and decreased in all mPFC subregions in CUS-14 animals (independent of prenatal treatment). Constrained principal component analysis, used to identify neural and behavioral networks, revealed that PAE altered the activation of these networks and modulated the effects of CUS on these networks in a sex- and time-dependent manner. This dysregulation of the neurocircuitry underlying behavioral, emotional and stress regulation, may ultimately contribute to an increased vulnerability to psychopathologies, such as depression, that are often observed following PAE.

The goal of this study was to determine if presbycusis disrupted spontaneous neural activity in specific brain areas involved in auditory processing, attention and cognitive function using resting-state functional magnetic resonance imaging (fMRI) approach. Methods: Hearing and resting-state fMRI measurements were obtained from 22 presbycusis patients and 23 age-, sex- and education-matched healthy controls. To identify changes in spontaneous neural activity associated with age-related hearing loss, we compared the amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) of fMRI signals in presbycusis patients vs. controls and then determined if these changes were linked to clinical measures of presbycusis. Results: Compared with healthy controls, presbycusis patients manifested decreased spontaneous activity mainly in the superior temporal gyrus (STG), parahippocampal gyrus (PHG), precuneus and inferior parietal lobule (IPL) as well as increased neural activity in the middle frontal gyrus (MFG), cuneus and postcentral gyrus (PoCG). A significant negative correlation was observed between ALFF/ReHo activity in the STG and average hearing thresholds in presbycusis patients. Increased ALFF/ReHo activity in the MFG was positively correlated with impaired Trail-Making Test B (TMT-B) scores, indicative of impaired cognitive function involving the frontal lobe. Conclusions: Presbycusis patients have disrupted spontaneous neural activity reflected by ALFF and ReHo measurements in several brain regions; these changes are associated with specific cognitive performance and speech/language processing. These findings mainly emphasize the crucial role of aberrant resting-state ALFF/ReHo patterns in presbycusis patients and will lead to a better understanding of the neuropathological mechanisms underlying presbycusis. PMID- 29593513 TI - Zebrafish Lacking Circadian Gene per2 Exhibit Visual Function Deficiency. AB - The retina has an intrinsic circadian clock, but the importance of this clock for vision is unknown. Zebrafish offer many advantages for studying vertebrate vision and circadian rhythm. Here, we explored the role of zebrafish per2, a light regulated gene, in visual behavior and the underlying mechanisms. We observed that per2 mutant zebrafish larvae showed decreased contrast sensitivity and visual acuity using optokinetic response (OKR) assays. Using a visual motor response (VMR) assay, we observed normal OFF responses but abnormal ON responses in mutant zebrafish larvae. Immunofluorescence showed that mutants had a normal morphology of cone photoreceptor cells and retinal organization. However, electron microscopy showed that per2 mutants displayed abnormal and decreased photoreceptor ribbon synapses with arciform density, which resulted in retinal ON pathway defect. We also examined the expression of three cone opsins by quantitative real-time PCR (qRT-PCR), and the expression of long-wave-sensitive opsin (opn1lw) and short-wave-sensitive opsin (opn1sw) was reduced in mutant zebrafish larvae. qRT-PCR analyses also showed a down-regulation of the clock genes cry1ba and bmal1b in the adult eye of per2 mutant zebrafish. This study identified a mechanism by which a clock gene affects visual function and defined important roles of per2 in retinal information processing. PMID- 29593514 TI - Lie Detection Using fNIRS Monitoring of Inhibition-Related Brain Regions Discriminates Infrequent but not Frequent Liars. AB - Functional near-infrared spectroscopy (fNIRS) was used to test whether monitoring inhibition-related brain regions is a feasible method for detecting both infrequent liars and frequent liars. Thirty-two participants were divided into two groups: the deceptive group (liars) and the non-deceptive group (ND group, innocents). All the participants were required to undergo a simulated interrogation by a computer. The participants from the deceptive group were instructed to tell a mix of lies and truths and those of the ND group were instructed always to tell the truth. Based on the number of deceptions, the participants of the deceptive group were further divided into a infrequently deceptive group (IFD group, infrequent liars) and a frequently deceptive group (FD group, frequent liars). The infrequent liars exhibited greater neural activities than the frequent liars and the innocents in the left middle frontal gyrus (MFG) when performing the deception detection tasks. While performing deception detection tasks, infrequent liars showed significantly greater neural activation in the left MFG than the baseline, but frequent liars and innocents did not exhibit this pattern of neural activation in any area of inhibition related brain regions. The results of individual analysis showed an acceptable accuracy of detecting infrequent liars, but an unacceptable accuracy of detecting frequent liars. These results suggest that using fNIRS monitoring of inhibition related brain regions is feasible for detecting infrequent liars, for whom deception may be more effortful and therefore more physiologically marked, but not frequent liars. PMID- 29593515 TI - Resting-State Brain Signal Variability in Prefrontal Cortex Is Associated With ADHD Symptom Severity in Children. AB - Atypical brain function in attention-deficit/hyperactivity disorder (ADHD) has been identified using both task-activation and functional connectivity fMRI approaches. Recent work highlights the potential for another measure derived from functional neuroimaging data, brain signal variability, to reveal insights into clinical conditions. Higher brain signal variability has previously been linked with optimal behavioral performance. At present, little is known regarding the relationship between resting-state brain signal variability and ADHD symptom severity. The current study examined the relationship between a measure of moment to-moment brain signal variability called mean-square successive difference (MSSD) and ADHD symptomatology in a group of children (7-12 years old) with (n = 40) and without (n = 30) a formal diagnosis of ADHD. A categorical analysis comparing subjects with and without a clinical diagnosis of ADHD showed no differences in MSSD between groups. A dimensional analysis revealed a positive relationship between MSSD and overall ADHD symptom severity and inattention across children with and without an ADHD diagnosis. Specifically, this positive relationship was found in medial prefrontal areas comprising the default mode network. These results demonstrate a link between intrinsic brain signal variability and ADHD symptom severity that cuts across diagnostic categories, and point to a locus of dysfunction consistent with previous neuroimaging literature. PMID- 29593511 TI - Noradrenergic Modulation of Fear Conditioning and Extinction. AB - The locus coeruleus norepinephrine (LC-NE) system plays a broad role in learning and memory. Here we begin with an overview of the LC-NE system. We then consider how both direct and indirect manipulations of the LC-NE system affect cued and contextual aversive learning and memory. We propose that NE dynamically modulates Pavlovian conditioning and extinction, either promoting or impairing learning aversive processes under different levels of behavioral arousal. We suggest that under high levels of stress (e.g., during/soon after fear conditioning) the locus coeruleus (LC) promotes cued fear learning by enhancing amygdala function while simultaneously blunting prefrontal function. Under low levels of arousal, the LC promotes PFC function to promote downstream inhibition of the amygdala and foster the extinction of cued fear. Thus, LC-NE action on the medial prefrontal cortex (mPFC) might be described by an inverted-U function such that it can either enhance or hinder learning depending on arousal states. In addition, LC-NE seems to be particularly important for the acquisition, consolidation and extinction of contextual fear memories. This may be due to dense adrenoceptor expression in the hippocampus (HPC) which encodes contextual information, and the ability of NE to regulate long-term potentiation (LTP). Moreover, recent work reveals that the diversity of LC-NE functions in aversive learning and memory are mediated by functionally heterogeneous populations of LC neurons that are defined by their projection targets. Hence, LC-NE function in learning and memory is determined by projection-specific neuromodulation that accompanies various states of behavioral arousal. PMID- 29593516 TI - Online Adaptation to Altered Auditory Feedback Is Predicted by Auditory Acuity and Not by Domain-General Executive Control Resources. AB - When a speaker's auditory feedback is altered, he adapts for the perturbation by altering his own production, which demonstrates the role of auditory feedback in speech motor control. In the present study, we explored the role of auditory acuity and executive control in this process. Based on the DIVA model and the major cognitive control models, we expected that higher auditory acuity, and better executive control skills would predict larger adaptation to the alteration. Thirty-six Spanish native speakers performed an altered auditory feedback experiment, executive control (numerical Stroop, Simon and Flanker) tasks, and auditory acuity tasks (loudness, pitch, and melody pattern discrimination). In the altered feedback experiment, participants had to produce the pseudoword "pep" (/pep/) while perceiving their auditory feedback in real time through earphones. The auditory feedback was first unaltered and then progressively altered in F1 and F2 dimensions until maximal alteration (F1 -150 Hz; F2 +300 Hz). The normalized distance of maximal adaptation ranged from 4 to 137 Hz (median of 75 +/- 36). The different measures of auditory acuity were significant predictors of adaptation, while individual measures of cognitive function skills (obtained from the executive control tasks) were not. Better auditory discriminators adapted more to the alteration. We conclude that adaptation to altered auditory feedback is very well-predicted by general auditory acuity, as suggested by the DIVA model. In line with the framework of motor-control models, no specific claim on the implication of executive resources in speech motor control can be made. PMID- 29593517 TI - Emotional Prosody Processing in Epilepsy: Some Insights on Brain Reorganization. AB - Drug resistant epilepsy is one of the most complex, multifactorial and polygenic neurological syndrome. Besides its dynamicity and variability, it still provides us with a model to study brain-behavior relationship, giving cues on the anatomy and functional representation of brain function. Given that onset zone of focal epileptic seizures often affects different anatomical areas, cortical but limited to one hemisphere, this condition also let us study the functional differences of the left and right cerebral hemispheres. One lateralized function in the human brain is emotional prosody, and it can be a useful ictal sign offering hints on the location of the epileptogenic zone. Besides its importance for effective communication, prosody is not considered an eloquent domain, making resective surgery on its neural correlates feasible. We performed an Electronic databases search (Medline and PsychINFO) from inception to July 2017 for studies about prosody in epilepsy. The search terms included "epilepsy," "seizure," "emotional prosody," and "vocal affect." This review focus on emotional prosody processing in epilepsy as it can give hints regarding plastic functional changes following seizures (preoperatively), resection (post operatively), and also as an ictal sign enabling the assessment of dynamic brain networks. Moreover, it is argued that such reorganization can help to preserve the expression and reception of emotional prosody as a central skill to develop appropriate social interactions. PMID- 29593518 TI - Task-Relevant Information Modulates Primary Motor Cortex Activity Before Movement Onset. AB - Monkey neurophysiology research supports the affordance competition hypothesis (ACH) proposing that cognitive information useful for action selection is integrated in sensorimotor areas. In this view, action selection would emerge from the simultaneous representation of competing action plans, in parallel biased by relevant task factors. This biased competition would take place up to primary motor cortex (M1). Although ACH is plausible in environments affording choices between actions, its relevance for human decision making is less clear. To address this issue, we designed an functional magnetic resonance imaging (fMRI) experiment modeled after monkey neurophysiology studies in which human participants processed cues conveying predictive information about upcoming button presses. Our results demonstrate that, as predicted by the ACH, predictive information (i.e., the relevant task factor) biases activity of primary motor regions. Specifically, first, activity before movement onset in contralateral M1 increases as the competition is biased in favor of a specific button press relative to activity in ipsilateral M1. Second, motor regions were more tightly coupled with fronto-parietal regions when competition between potential actions was high, again suggesting that motor regions are also part of the biased competition network. Our findings support the idea that action planning dynamics as proposed in the ACH are valid both in human and non-human primates. PMID- 29593519 TI - Evolving Simple Models of Diverse Intrinsic Dynamics in Hippocampal Neuron Types. AB - The diversity of intrinsic dynamics observed in neurons may enhance the computations implemented in the circuit by enriching network-level emergent properties such as synchronization and phase locking. Large-scale spiking network models of entire brain regions offer a platform to test theories of neural computation and cognitive function, providing useful insights on information processing in the nervous system. However, a systematic in-depth investigation requires network simulations to capture the biological intrinsic diversity of individual neurons at a sufficient level of accuracy. The computationally efficient Izhikevich model can reproduce a wide range of neuronal behaviors qualitatively. Previous studies using optimization techniques, however, were less successful in quantitatively matching experimentally recorded voltage traces. In this article, we present an automated pipeline based on evolutionary algorithms to quantitatively reproduce features of various classes of neuronal spike patterns using the Izhikevich model. Employing experimental data from Hippocampome.org, a comprehensive knowledgebase of neuron types in the rodent hippocampus, we demonstrate that our approach reliably fit Izhikevich models to nine distinct classes of experimentally recorded spike patterns, including delayed spiking, spiking with adaptation, stuttering, and bursting. Importantly, by leveraging the parameter-exploration capabilities of evolutionary algorithms, and by representing qualitative spike pattern class definitions in the error landscape, our approach creates several suitable models for each neuron type, exhibiting appropriate feature variabilities among neurons. Moreover, we demonstrate the flexibility of our methodology by creating multi-compartment Izhikevich models for each neuron type in addition to single-point versions. Although the results presented here focus on hippocampal neuron types, the same strategy is broadly applicable to any neural systems. PMID- 29593521 TI - Hierarchical Spatial Concept Formation Based on Multimodal Information for Human Support Robots. AB - In this paper, we propose a hierarchical spatial concept formation method based on the Bayesian generative model with multimodal information e.g., vision, position and word information. Since humans have the ability to select an appropriate level of abstraction according to the situation and describe their position linguistically, e.g., "I am in my home" and "I am in front of the table," a hierarchical structure of spatial concepts is necessary in order for human support robots to communicate smoothly with users. The proposed method enables a robot to form hierarchical spatial concepts by categorizing multimodal information using hierarchical multimodal latent Dirichlet allocation (hMLDA). Object recognition results using convolutional neural network (CNN), hierarchical k-means clustering result of self-position estimated by Monte Carlo localization (MCL), and a set of location names are used, respectively, as features in vision, position, and word information. Experiments in forming hierarchical spatial concepts and evaluating how the proposed method can predict unobserved location names and position categories are performed using a robot in the real world. Results verify that, relative to comparable baseline methods, the proposed method enables a robot to predict location names and position categories closer to predictions made by humans. As an application example of the proposed method in a home environment, a demonstration in which a human support robot moves to an instructed place based on human speech instructions is achieved based on the formed hierarchical spatial concept. PMID- 29593520 TI - IClinfMRI Software for Integrating Functional MRI Techniques in Presurgical Mapping and Clinical Studies. AB - Task-evoked and resting-state (rs) functional magnetic resonance imaging (fMRI) techniques have been applied to the clinical management of neurological diseases, exemplified by presurgical localization of eloquent cortex, to assist neurosurgeons in maximizing resection while preserving brain functions. In addition, recent studies have recommended incorporating cerebrovascular reactivity (CVR) imaging into clinical fMRI to evaluate the risk of lesion induced neurovascular uncoupling (NVU). Although each of these imaging techniques possesses its own advantage for presurgical mapping, a specialized clinical software that integrates the three complementary techniques and promptly outputs the analyzed results to radiology and surgical navigation systems in a clinical format is still lacking. We developed the Integrated fMRI for Clinical Research (IClinfMRI) software to facilitate these needs. Beyond the independent processing of task-fMRI, rs-fMRI, and CVR mapping, IClinfMRI encompasses three unique functions: (1) supporting the interactive rs-fMRI mapping while visualizing task fMRI results (or results from published meta-analysis) as a guidance map, (2) indicating/visualizing the NVU potential on analyzed fMRI maps, and (3) exporting these advanced mapping results in a Digital Imaging and Communications in Medicine (DICOM) format that are ready to export to a picture archiving and communication system (PACS) and a surgical navigation system. In summary, IClinfMRI has the merits of efficiently translating and integrating state-of-the art imaging techniques for presurgical functional mapping and clinical fMRI studies. PMID- 29593522 TI - Frontoparietal tDCS Benefits Visual Working Memory in Older Adults With Low Working Memory Capacity. AB - Working memory (WM) permits maintenance of information over brief delays and is an essential executive function. Unfortunately, WM is subject to age-related decline. Some evidence supports the use of transcranial direct current stimulation (tDCS) to improve visual WM. A gap in knowledge is an understanding of the mechanism characterizing these tDCS linked effects. To address this gap, we compared the effects of two tDCS montages designed on visual working memory (VWM) performance. The bifrontal montage was designed to stimulate the heightened bilateral frontal activity observed in aging adults. The unilateral frontoparietal montage was designed to stimulate activation patterns observed in young adults. Participants completed three sessions (bilateral frontal, right frontoparietal, sham) of anodal tDCS (20 min, 2 mA). During stimulation, participants performed a visual long-term memory (LTM) control task and a visual WM task. There was no effect of tDCS on the LTM task. Participants receiving right unilateral tDCS showed a WM benefit. This pattern was most robust in older adults with low WM capacity. To address the concern that the key difference between the two tDCS montages could be tDCS over the posterior parietal cortex (PPC), we included new analyses from a previous study applying tDCS targeting the PPC paired with a recognition VWM task. No significant main effects were found. A subsequent experiment in young adults found no significant effect of either tDCS montage on either task. These data indicate that tDCS montage, age and WM capacity should be considered when designing tDCS protocols. We interpret these findings as suggestive that protocols designed to restore more youthful patterns of brain activity are superior to those that compensate for age-related changes. PMID- 29593523 TI - Functional Hemispheric (A)symmetries in the Aged Brain-Relevance for Working Memory. AB - Functional hemispheric asymmetries have been described in different cognitive processes, such as decision-making and motivation. Variations in the pattern of left/right activity have been associated with normal brain functioning, and with neuropsychiatric diseases. Such asymmetries in brain activity evolve throughout life and are thought to decrease with aging, but clear associations with cognitive function have never been established. Herein, we assessed functional laterality during a working memory task (N-Back) in a healthy aging cohort (over 50 years old) and associated these asymmetries with performance in the test. Activity of lobule VI of the cerebellar hemisphere and angular gyrus was found to be lateralized to the right hemisphere, while the precentral gyrus presented left > right activation during this task. Interestingly, 1-Back accuracy was positively correlated with left > right superior parietal lobule activation, which was mostly due to the influence of the left hemisphere. In conclusion, although regions were mostly symmetrically activated during the N-Back task, performance in working memory in aged individuals seems to benefit from lateralized involvement of the superior parietal lobule. PMID- 29593524 TI - The Association of Aging and Aerobic Fitness With Memory. AB - The present study examined the differential effects of aging and fitness on memory. Ninety-five young adults (YA) and 81 older adults (OA) performed the Mnemonic Similarity Task (MST) to assess high-interference memory and general recognition memory. Age-related differences in high-interference memory were observed across the lifespan, with performance progressively worsening from young to old. In contrast, age-related differences in general recognition memory were not observed until after 60 years of age. Furthermore, OA with higher aerobic fitness had better high-interference memory, suggesting that exercise may be an important lifestyle factor influencing this aspect of memory. Overall, these findings suggest different trajectories of decline for high-interference and general recognition memory, with a selective role for physical activity in promoting high-interference memory. PMID- 29593526 TI - Tricaproin Isolated From Simarouba glauca Inhibits the Growth of Human Colorectal Carcinoma Cell Lines by Targeting Class-1 Histone Deacetylases. AB - While anticancer properties of Simarouba glauca (SG, commonly known as Paradise tree) are well documented in ancient literature, the underlying mechanisms leading to cancer cell death begin to emerge very recently. The leaves of SG have been used as potential source of anticancer agents in traditional medicine. Recently attempts have been made to isolate anticancer agents from the leaves of SG using solvent extraction, which identified quassinoids as the molecules with tumoricidal activity. However, it is not known whether the anti-cancer potential of SG leaves is just because of quassinoids alone or any other phytochemicals also contribute for the potency of SG leaf extracts. Therefore, SG leaves were first extracted with hexane, chloroform, ethyl acetate, 70% ethanol, water and anti-cancer potential (for inhibiting colorectal cancer (CRC) cells HCT-116 and HCT-15 proliferation) determined using Sulforhodamine-B (SRB) assay. The chloroform fraction with maximal anticancer activity was further fractionated by activity-guided isolation procedure and structure of the most potent compound determined using spectral analysis. Analysis of the structural characterization data showed the presence of tricaproin (TCN). TCN inhibited CRC cells growth in a time- and dose dependent manner but not the normal cell line BEAS-2B. Mechanistically, TCN reduced oncogenic Class-I Histone deacetylases (HDACs) activity, followed by inducing apoptosis in cells. In conclusion, the anti-cancer potential of SG is in part due to the presence of TCN in the leaves. PMID- 29593528 TI - A Statistical Thermodynamic Model for Ligands Interacting With Ion Channels: Theoretical Model and Experimental Validation of the KCNQ2 Channel. AB - Ion channels are important therapeutic targets, and their pharmacology is becoming increasingly important. However, knowledge of the mechanism of interaction of the activators and ion channels is still limited due to the complexity of the mechanisms. A statistical thermodynamic model has been developed in this study to characterize the cooperative binding of activators to ion channels. By fitting experimental concentration-response data, the model gives eight parameters for revealing the mechanism of an activator potentiating an ion channel, i.e., the binding affinity (KA ), the binding cooperative coefficients for two to four activator molecules interacting with one channel (gamma, MU, and nu), and the channel conductance coefficients for four activator binding configurations of the channel (a, b, c, and d). Values for the model parameters and the mechanism underlying the interaction of ztz240, a proven KCNQ2 activator, with the wild-type channel have been obtained and revealed by fitting the concentration-response data of this activator potentiating the outward current amplitudes of KCNQ2. With these parameters, our model predicted an unexpected bi-sigmoid concentration-response curve of ztz240 activation of the WT F137A mutant heteromeric channel that was in good agreement with the experimental data determined in parallel in this study, lending credence to the assumptions on which the model is based and to the model itself. Our model can provide a better fit to the measured data than the Hill equation and estimates the binding affinity, as well as the cooperative coefficients for the binding of activators and conductance coefficients for binding states, which validates its use in studying ligand-channel interaction mechanisms. PMID- 29593525 TI - The Aging of Iron Man. AB - Brain iron is tightly regulated by a multitude of proteins to ensure homeostasis. Iron dyshomeostasis has become a molecular signature associated with aging which is accompanied by progressive decline in cognitive processes. A common theme in neurodegenerative diseases where age is the major risk factor, iron dyshomeostasis coincides with neuroinflammation, abnormal protein aggregation, neurodegeneration, and neurobehavioral deficits. There is a great need to determine the mechanisms governing perturbations in iron metabolism, in particular to distinguish between physiological and pathological aging to generate fruitful therapeutic targets for neurodegenerative diseases. The aim of the present review is to focus on the age-related alterations in brain iron metabolism from a cellular and molecular biology perspective, alongside genetics, and neuroimaging aspects in man and rodent models, with respect to normal aging and neurodegeneration. In particular, the relationship between iron dyshomeostasis and neuroinflammation will be evaluated, as well as the effects of systemic iron overload on the brain. Based on the evidence discussed here, we suggest a synergistic use of iron-chelators and anti-inflammatories as putative anti-brain aging therapies to counteract pathological aging in neurodegenerative diseases. PMID- 29593529 TI - Pathway-Based Analysis of Genome-Wide Association Data Identified SNPs in HMMR as Biomarker for Chemotherapy- Induced Neutropenia in Breast Cancer Patients. AB - Neutropenia secondary to chemotherapy in breast cancer patients can be life threatening and there are no biomarkers available to predict the risk of drug induced neutropenia in those patients. We previously performed a genome-wide association study (GWAS) for neutropenia events in women with breast cancer who were treated with 5-fluorouracil, epirubicin and cyclophosphamide and recruited to the SUCCESS-A trial. A genome-wide significant single-nucleotide polymorphism (SNP) signal in the tumor necrosis factor superfamily member 13B (TNFSF13B) gene, encoding the cytokine B-cell activating factor (BAFF), was identified in that GWAS. Taking advantage of these existing GWAS data, in the present study we utilized a pathway-based analysis approach by leveraging knowledge of the pharmacokinetics and pharmacodynamics of drugs and breast cancer pathophysiology to identify additional SNPs/genes associated with the underlying etiology of chemotherapy-induced neutropenia. We identified three SNPs in the hyaluronan mediated motility receptor (HMMR) gene that were significantly associated with neutropenia (p < 1.0E-04). Those three SNPs were trans-expression quantitative trait loci for the expression of TNFSF13B (p < 1.0E-04). The minor allele of these HMMR SNPs was associated with a decreased TNFSF13B mRNA level. Additional functional studies performed with lymphoblastoid cell lines (LCLs) demonstrated that LCLs possessing the minor allele for the HMMR SNPs were more sensitive to drug treatment. Knock-down of TNFSF13B in LCLs and HL-60 promyelocytic cells and treatment of those cells with BAFF modulated the cell sensitivity to chemotherapy treatment. These results demonstrate that HMMR SNP-dependent cytotoxicity of these chemotherapeutic agents might be related to TNFSF13B expression level. In summary, utilizing a pathway-based approach for the analysis of GWAS data, we identified additional SNPs in the HMMR gene that were associated with neutropenia and also were correlated with TNFSF13B expression. PMID- 29593527 TI - Exploring G Protein-Coupled Receptors (GPCRs) Ligand Space via Cheminformatics Approaches: Impact on Rational Drug Design. AB - The primary goal of rational drug discovery is the identification of selective ligands which act on single or multiple drug targets to achieve the desired clinical outcome through the exploration of total chemical space. To identify such desired compounds, computational approaches are necessary in predicting their drug-like properties. G Protein-Coupled Receptors (GPCRs) represent one of the largest and most important integral membrane protein families. These receptors serve as increasingly attractive drug targets due to their relevance in the treatment of various diseases, such as inflammatory disorders, metabolic imbalances, cardiac disorders, cancer, monogenic disorders, etc. In the last decade, multitudes of three-dimensional (3D) structures were solved for diverse GPCRs, thus referring to this period as the "golden age for GPCR structural biology." Moreover, accumulation of data about the chemical properties of GPCR ligands has garnered much interest toward the exploration of GPCR chemical space. Due to the steady increase in the structural, ligand, and functional data of GPCRs, several cheminformatics approaches have been implemented in its drug discovery pipeline. In this review, we mainly focus on the cheminformatics-based paradigms in GPCR drug discovery. We provide a comprehensive view on the ligand- and structure-based cheminformatics approaches which are best illustrated via GPCR case studies. Furthermore, an appropriate combination of ligand-based knowledge with structure-based ones, i.e., integrated approach, which is emerging as a promising strategy for cheminformatics-based GPCR drug design is also discussed. PMID- 29593530 TI - Mitochondrial Fission Is Required for Angiotensin II-Induced Cardiomyocyte Apoptosis Mediated by a Sirt1-p53 Signaling Pathway. AB - Hypertension-induced cardiac apoptosis is a major contributor to early-stage heart-failure. Our previous studies have found that p53-mediated mitochondrial fission is involved in aldosterone-induced podocyte apoptosis. However, it is not clear that whether p53-induced mitochondrial fission is critical for hypertensive Angiotensin II (AngII)-induced cardiomyocyte apoptosis. In this study, we found that inhibition of the mitochondrial fission protein Drp1 (dynamin-related protein 1) by Mdivi-1 prevented cardiomyocyte apoptosis and cardiac remodeling in SHRs. In vitro we found that treatment of cultured neonatal rat cardiomyocytes with AngII induced Drp1 expression, mitochondrial fission, and apoptosis. Knockdown of Drp1 inhibited AngII-induced mitochondrial fission and cardiomyocyte apoptosis. Furthermore, AngII induced p53 acetylation. Knockdown of p53 inhibited AngII-induced Drp1 expression, mitochondrial fission, and cardiomyocyte apoptosis. Besides, we found that Sirt1 was able to reverse AngII-induced p53 acetylation and its binding to the Drp1 promoter, which subsequently inhibited mitochondrial fission and eventually attenuated cardiomyocyte apoptosis. Collectively, these results suggest that AngII degrades Sirt1 to increase p53 acetylation, which induces Drp1 expression and eventually results in cardiomyocyte apoptosis. Sirt1/p53/Drp1dependent mitochondrial fission may be a valuable therapeutic target for hypertension induced heart failure. PMID- 29593531 TI - Stereoisomers of Saponins in Panax notoginseng (Sanqi): A Review. AB - Panax notoginseng (Sanqi), a traditional Chinese medical drug which has been applied to medical use for over four centuries, contains high content of dammarane-type tetracyclic triterpenoid saponins. A number of stereoisomeric dammarane-type saponins exist in this precious herb, and some are particularly regarded as "biomarkers" in processed notoginseng. Contemporary researches have indicated that some saponin stereoisomers may show stereospecific pharmacological activities, such as anti-tumor, antioxidative, anti-photoaging, anti inflammatory, antidiabetic, and neuro-protective activities, as well as stereoselective effects on ion channel current regulation, cardiovascular system, and immune system. The current review provides a comprehensive overview of chemical compositions of raw and processed P. notoginseng with a particular emphasis on saponin stereoisomers. Besides, the pharmacological and pharmacokinetic researches, as well as determination and biotechnological preparation methods of stereoisomeric saponins in notoginseng are discussed extensively. PMID- 29593533 TI - A New Search Method Using Association Rule Mining for Drug-Drug Interaction Based on Spontaneous Report System. AB - Background: Adverse events (AEs) can be caused not only by one drug but also by the interaction between two or more drugs. Therefore, clarifying whether an AE is due to a specific suspect drug or drug-drug interaction (DDI) is useful information for proper use of drugs. Whereas previous reports on the search for drug-induced AEs with signal detection using spontaneous reporting systems (SRSs) are numerous, reports on drug interactions are limited. This is because in methods that use "a safety signal indicator" (signal), which is frequently used in pharmacovigilance, a huge number of combinations must be prepared when signal detection is performed, and each risk index must be calculated, which makes interaction search appear unrealistic. Objective: In this paper, we propose association rule mining (AR) using large dataset analysis as an alternative to the conventional methods (additive interaction model (AI) and multiplicative interaction model (MI)). Methods: The data source used was the Japanese Adverse Drug Event Report database. The combination of drugs for which the risk index is detected by the "combination risk ratio (CR)" as the target was assumed to be true data, and the accuracy of signal detection using the AR methods was evaluated in terms of sensitivity, specificity, Youden's index, F-score. Results: Our experimental results targeting Stevens-Johnson syndrome indicate that AR has a sensitivity of 99.05%, specificity of 92.60%, Youden's index of 0.917, F-score of 0.876, AI has a sensitivity of 95.62%, specificity of 96.92%, Youden's index of 0.925, and F-score of 0.924, and MI has a sensitivity of 65.46%, specificity of 98.78%, Youden's index of 0.642, and F-score of 0.771. This result was about the same level as or higher than the conventional method. Conclusions: If you use similar calculation methods to create combinations from the database, not only for SJS, but for all AEs, the number of combinations would be so enormous that it would be difficult to perform the calculations. However, in the AR method, the "Apriori algorithm" is used to reduce the number of calculations. Thus, the proposed method has the same detection power as the conventional methods, with the significant advantage that its calculation process is simple. PMID- 29593532 TI - (-)-Epigallocatechin-3-Gallate Ameliorates Atherosclerosis and Modulates Hepatic Lipid Metabolic Gene Expression in Apolipoprotein E Knockout Mice: Involvement of TTC39B. AB - Background: Aberrant chronic inflammation and excess accumulation of lipids play a pivotal role in the occurrence and progression of atherosclerosis. (-) Epigallocatechin-3-gallate (EGCG), the major catechins in green tea, displayed anti-atherosclerotic properties in vivo and in vitro. However, the effects and underlying mechanism of EGCG on atherosclerosis remain unclear. Methods: Male apolipoprotein E-knockout (ApoE-/-) mice (7 weeks old) fed with high-fat diet (HFD) were treated with normal saline or EGCG (40 mg/kg/d, i.g.) for 18 weeks. Atherosclerotic plaque and liver lipid accumulation were measured by Oil Red staining. Plasma lipids and cytokines were detected using commercial kits. The expression of protein and mRNA was analyzed by western blot and quantitative real time reverse transcription-polymerase chain reaction, respectively. Results: EGCG administration markedly attenuated atherosclerotic plaque formation in HFD-fed ApoE-/- mice, which were accompanied by increased plasma interleukin-10 (IL-10) level and decreased plasma IL-6 and tumor necrosis factor-alpha (TNF-alpha) levels. In addition, EGCG modulated high-fat-induced dyslipidemia, evidencing by decreased total cholesterol (TC) and low-density lipoprotein levels and increased high-density lipoprotein level. Meanwhile, EGCG treatment alleviated high-fat mediated liver lipid accumulation and decreased liver TC and triglyceride. Mechanistically, EGCG significantly modulated high-fat-induced hepatic tetratricopeptide repeat domain protein 39B (TTC39B) expression and its related genes (Lxrbeta, Abcg5, Abcg8, Abca1, Srebf1, Scd1, Scd2, Fas, Elovl5, Mylip) expression in liver from ApoE-/- mice. Notably, EGCG remarkably induced hepatic liver X receptor alpha (LXRalpha) and LXRbeta expression and inhibited both precursor and mature sterol regulatory element binding transcription factor-1 (SREBP-1) expression. Conclusion: Taken together, our data for the first time suggested that TTC39B was involved in EGCG-mediated anti-atherosclerotic effects through modulation of LXR/SREBP-1 pathway. PMID- 29593534 TI - East Indian Sandalwood Oil Is a Phosphodiesterase Inhibitor: A New Therapeutic Option in the Treatment of Inflammatory Skin Disease. AB - Cyclic adenosine monophosphate phosphodiesterases (PDEs) regulate pro inflammatory cytokine production. One isoform, PDE4, is overactive in chronic relapsing inflammatory skin diseases: psoriasis and eczema/atopic dermatitis, and in several cancers. East Indian sandalwood oil (EISO) has significant anti inflammatory properties. Here, we report that 75% of pediatric eczema/atopic dermatitis patients treated with topical EISO formulations achieved a >50% reduction in their Eczema Area and Severity Index score. EISO treatment of a psoriasis model reduced PDE4 expression and reversed histopathology. EISO directly inhibited PDE enzymatic activity in vitro. In lipopolysaccharide stimulated human dermal fibroblast, BEAS-2B, A549, and THP-1 cells, EISO suppressed total cellular PDE activity, PDE4, and 7 transcript levels, nuclear factor kappa B (NF-kappaB) activation, and pro-inflammatory cytokines/chemokine production. These results suggest that EISO anti-inflammatory activity is mediated through suppressing PDE activity, thus facilitating cAMP-regulated inhibition of NF-kappaB and indicate EISO as an attractive natural therapeutic for chronic and acute inflammatory disorders. PMID- 29593535 TI - Vortioxetine Improves Context Discrimination in Mice Through a Neurogenesis Independent Mechanism. AB - Major Depressive Disorders (MDD) patients may exhibit cognitive deficits and it is currently unclear to which degree treatment with antidepressants may affect cognitive function. Preclinical and clinical observations showed that vortioxetine (VORT, an antidepressant with multimodal activity), presents beneficial effects on aspects of cognitive function. In addition, VORT treatment increases adult hippocampal neurogenesis (AHN) in rodents, a candidate mechanism for antidepressant activity. Pattern separation (PS) is the ability to discriminate between two similar contexts/events generating two distinct and non overlapping representations. Impaired PS may lead to overgeneralization and anxiety disorders. If PS impairments were described in depressed patients, the consequences of antidepressant treatment on context discrimination (CD) are still in its infancy. We hypothesized that VORT-increased AHN may improve CD. Thus, in an attempt to elucidate the molecular mechanism underpinning VORT treatment effects on CD, a rodent model of PS, the role of AHN and stress-induced c-Fos activation was evaluated in the adult mouse hippocampus. Chronic treatment with VORT (1.8 g/kg of food weight; corresponding to a daily dose of 10 mg/kg, 3 weeks) improved CD in mice. Interestingly, chronic treatment with VORT reversed ablation of AHN-induced delay in CD and freezing behavior. VORT treatment decreased stress-induced c-Fos activation in the dorsal but not ventral dentate gyrus. VORT treatment did not affect c-Fos activity in the hippocampus of mice with ablated neurogenesis. This study highlights a role of VORT in CD, which may be independent from AHN and hippocampal c-Fos activation. Further studies elucidating the mechanisms underlying VORT's effects in CD could contribute to future strategies for alleviating the disease burden for individuals suffering from depression and/or anxiety disorders. PMID- 29593536 TI - A Novel Dual HDAC6 and Tubulin Inhibitor, MPT0B451, Displays Anti-tumor Ability in Human Cancer Cells in Vitro and in Vivo. AB - The combination cancer therapy is a new strategy to circumvent drug resistance for the treatment of high metastasis and advanced malignancies. Herein, we developed a synthesized compound MPT0B451 that display inhibitory effect against histone deacetylase (HDAC) 6 and tubulin assembly. Our data demonstrated that MPT0B451 significantly inhibited cancer cell growths in HL-60 and PC-3 cells due to inhibition of HDAC activity. MPT0B451 also markedly increased caspase-mediated apoptosis in these cells. The cell cycle analysis showed mitotic arrest induced by MPT0B451 with enhanced expression of G2/M transition proteins. Moreover, molecular docking analysis supported MPT0B451 as a dual HDAC6 and tubulin inhibitor. Finally, MPT0B451 led to tumor growth inhibition (TGI) in HL-60 and PC 3 xenograft models. These findings indicated that MPT0B451 has dual inhibition effects for HDAC6 and tubulin, and also contributed to G2/M arrest followed by apoptotic induction. Together, our results suggested that MPT0B451 may serve as a potent anti-cancer treatment regimen in human prostate cancer and acute myeloid leukemia. PMID- 29593537 TI - Acute Pharmacological Effects of 2C-B in Humans: An Observational Study. AB - 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenylethylamine derivative, structurally similar to mescaline. It is a serotonin 5 hydroxytryptamine-2A (5-HT2A), 5-hydroxytryptamine-2B (5-HT2B), and 5 hydroxytryptamine-2C (5-HT2C) receptor partial agonist used recreationally as a new psychoactive substance. It has been reported that 2C-B induces mild psychedelic effects, although its acute pharmacological effects and pharmacokinetics have not yet been fully studied in humans. An observational study was conducted to assess the acute subjective and physiological effects, as well as pharmacokinetics of 2C-B. Sixteen healthy, experienced drug users self administered an oral dose of 2C-B (10, 15, or 20 mg). Vital signs (blood pressure and heart rate) were measured at baseline 1, 2, 3, 4, and 6 hours (h). Each participant completed subjective effects using three rating scales: the visual analog scale (VAS), the Addiction Research Centre Inventory (ARCI), and the Evaluation of the Subjective Effects of Substances with Abuse Potential (VESSPA SSE) at baseline, 2-3 and 6 h after self-administration (maximum effects along 6 h), and the Hallucinogenic Rating Scale (maximum effects along 6 h). Oral fluid (saliva) was collected to assess 2C-B and cortisol concentrations during 24 h. Acute administration of 2C-B increased blood pressure and heart rate. Scores of scales related to euphoria increased (high, liking, and stimulated), and changes in perceptions (distances, colors, shapes, and lights) and different body feelings/surrounding were produced. Mild hallucinating effects were described in five subjects. Maximum concentrations of 2C-B and cortisol were reached at 1 and 3 h after self-administration, respectively. Oral 2C-B at recreational doses induces a constellation of psychedelic/psychostimulant-like effects similar to those associated with serotonin-acting drugs. PMID- 29593538 TI - Salidroside Inhibits Myogenesis by Modulating p-Smad3-Induced Myf5 Transcription. AB - Aim: Salidroside is an active compound extracted from Rhodiola rosea which is used to alleviate fatigue and enhance endurance in high altitude regions. Some studies have demonstrated that salidroside can affect precursor cell differentiation in hematopoietic stem cells, erythrocytes, and osteoblasts. The aim of this study was to investigate the effect of salidroside on myoblast differentiation and to explore the underlying molecular mechanisms of this effect. Methods: C2C12 myoblast cells were treated with different concentrations of salidroside in differentiation media. Real-time PCR, Western blotting, and immunofluorescence assay were employed to evaluate the effects of salidroside on C2C12 differentiation. RNA interference was used to reveal the important role of Myf5 in myogenesis inhibited by salidroside. Chromatin Immunoprecipitation and dual-luciferase reporter assay were utilized to explore the underlying mechanisms of salidroside-induced upregulation of Myf5. Results: We found that salidroside inhibits myogenesis by downregulating MyoD and myogenin, preserves undifferentiated reserve cell pools by upregulating Myf5. Knocking down Myf5 expression significantly rescued the myogenesis inhibited by salidroside. The effect of salidroside on myogenesis was associated with increased phosphorylated Smad3 (p-Smad3). Both SIS3 (Specific inhibitor of p-Smad3) and dominant negative Smad3 plasmid (DN-Smad3) attenuated the inhibitory effect of salidroside on C2C12 differentiation. Moreover, the induction of Myf5 transcription by salidroside was dependent on a Smad-binding site in the promoter region of Myf5 gene. Conclusion and Implications: Our findings identify a novel role and mechanism for salidroside in regulating myogenesis through p-Smad3-induced Myf5 transcription, which may have implications for its further application in combating degenerative muscular diseases caused by depletion of muscle stem cells, such as Duchenne muscular dystrophy or sarcopenia. PMID- 29593539 TI - Optimization of Cholinesterase-Based Catalytic Bioscavengers Against Organophosphorus Agents. AB - Organophosphorus agents (OPs) are irreversible inhibitors of acetylcholinesterase (AChE). OP poisoning causes major cholinergic syndrome. Current medical counter measures mitigate the acute effects but have limited action against OP-induced brain damage. Bioscavengers are appealing alternative therapeutic approach because they neutralize OPs in bloodstream before they reach physiological targets. First generation bioscavengers are stoichiometric bioscavengers. However, stoichiometric neutralization requires administration of huge doses of enzyme. Second generation bioscavengers are catalytic bioscavengers capable of detoxifying OPs with a turnover. High bimolecular rate constants (kcat/Km > 106 M 1min-1) are required, so that low enzyme doses can be administered. Cholinesterases (ChE) are attractive candidates because OPs are hemi-substrates. Moderate OP hydrolase (OPase) activity has been observed for certain natural ChEs and for G117H-based human BChE mutants made by site-directed mutagenesis. However, before mutated ChEs can become operational catalytic bioscavengers their dephosphylation rate constant must be increased by several orders of magnitude. New strategies for converting ChEs into fast OPase are based either on combinational approaches or on computer redesign of enzyme. The keystone for rational conversion of ChEs into OPases is to understand the reaction mechanisms with OPs. In the present work we propose that efficient OP hydrolysis can be achieved by re-designing the configuration of enzyme active center residues and by creating specific routes for attack of water molecules and proton transfer. Four directions for nucleophilic attack of water on phosphorus atom were defined. Changes must lead to a novel enzyme, wherein OP hydrolysis wins over competing aging reactions. Kinetic, crystallographic, and computational data have been accumulated that describe mechanisms of reactions involving ChEs. From these studies, it appears that introducing new groups that create a stable H-bonded network susceptible to activate and orient water molecule, stabilize transition states (TS), and intermediates may determine whether dephosphylation is favored over aging. Mutations on key residues (L286, F329, F398) were considered. QM/MM calculations suggest that mutation L286H combined to other mutations favors water attack from apical position. However, the aging reaction is competing. Axial direction of water attack is not favorable to aging. QM/MM calculation shows that F329H+F398H-based multiple mutants display favorable energy barrier for fast reactivation without aging. PMID- 29593540 TI - Purinergic Ligands as Potential Therapeutic Tools for the Treatment of Inflammation-Related Intestinal Diseases. AB - Inflammation-related intestinal diseases are a set of various conditions presenting an overactive enteric immune system. A continuous overproduction of pro-inflammatory cytokines and a decreased production of anti-inflammatory modulators are generally observed, while morpho-functional alterations of the enteric nervous system lead to intestinal secretory and motor dysfunctions. The factors at the basis of these conditions are still to be totally identified and current therapeutic strategies are aimed only at achieving and maintaining remission states, by using therapeutic tools like aminosalicylates, corticosteroids, immunomodulators, biological drugs (i.e., monoclonal antibodies), and eventually surgery. Recent reports described a key role of purinergic mediators (i.e., adenosine and its nucleotides ATP and ADP) in the regulation of the activity of immune cells and enteric nervous system, showing also that alterations of the purinergic signaling are linked to pathological conditions of the intestinal tract. These data prompted to a series of investigations to test the therapeutic potential for inflammation-related intestinal conditions of compounds able to restore or modulate an altered purinergic signaling within the gut. This review provides an overview on these investigations, describing the results of preclinical and/or clinical evaluation of compounds able to stimulate or inhibit specific P2 (i.e., P2X7) or P1 (i.e., A2A or A3) receptor signaling and to modify the adenosine levels through the modulation of enzymes activity (i.e., Adenosine Deaminase) or nucleoside transporters. Recent developments in the field are also reported and the most promising purine-based therapeutic strategies for the treatment of inflammation related gastrointestinal disorders are schematically summarized. PMID- 29593541 TI - A Preliminary Investigation on Smokeless Tobacco Use and Its Cognitive Effects Among Athletes. AB - Introduction: Among athletes, an increasing use of nicotine via smokeless tobacco has been reported. However, there are currently unanswered questions about whether the use by athletes is due to nicotine's addictive properties and/or to benefits in physical and cognitive performance (e.g., decision-making). In this original article we reported about, (i) snus-induced reinforcing effects among snus-user athletes (Survey) and (ii) the effects of snus on the Iowa Gambling Task (IGT) in snus-user skiers (Experimental study). IGT is an experimental neuropsychological task that has been previously used on athletes and addicts to test decision-making. Methods: Survey: data were collected with the modified Cigarette Evaluation Questionnaire (mCEQ) that was administered to 61 winter sport athlete snus-users in Northern Italy. Experimental study: IGT data included: amount of money earned, number of choices from advantageous and disadvantageous decks and overall net score. Eighteen male snus-users were tested under satiety or after 12-h abstinence conditions according to a crossover design. Results: Survey: the comparison between occasional vs. regular snus-users showed a statistically significant difference in satisfaction (P = 0.0088), calm (P = 0.0252), and enjoyment (P = 0.0001) mCEQ items suggesting a snus intake/effect relationship. Experimental study: significantly higher IGT net scores were found during the first 20 choice cards after abstinence vs. satiety conditions (P = 0.0024). Conclusion: In the Survey, regular snus use induces greater satisfaction and psychological reward than occasional use. In the Experimental study, snus intake might produce an early and transient cognitive improvement on IGT in abstinent snus-users, presumably acting as a withdrawal relief. PMID- 29593542 TI - Apigenin and Luteolin Attenuate the Breaching of MDA-MB231 Breast Cancer Spheroids Through the Lymph Endothelial Barrier in Vitro. AB - Flavonoids, present in fruits, vegetables and traditional medicinal plants, show anticancer effects in experimental systems and are reportedly non-toxic. This is a favorable property for long term strategies for the attenuation of lymph node metastasis, which may effectively improve the prognostic states in breast cancer. Hence, we studied two flavonoids, apigenin and luteolin exhibiting strong bio activity in various test systems in cancer research and are readily available on the market. This study has further advanced the mechanistic understanding of breast cancer intravasation through the lymphatic barrier. Apigenin and luteolin were tested in a three-dimensional (3-D) assay consisting of MDA-MB231 breast cancer spheroids and immortalized lymph endothelial cell (LEC) monolayers. The 3 D model faithfully resembles the intravasation of breast cancer emboli through the lymphatic vasculature. Western blot analysis, intracellular Ca2+ determination, EROD assay and siRNA transfection revealed insights into mechanisms of intravasation as well as the anti-intravasative outcome of flavonoid action. Both flavonoids suppressed pro-intravasative trigger factors in MDA-MB231 breast cancer cells, specifically MMP1 expression and CYP1A1 activity. A pro-intravasative contribution of FAK expression in LECs was established as FAK supported the retraction of the LEC monolayer upon contact with cancer cells thereby enabling them to cross the endothelial barrier. As mechanistic basis, MMP1 caused the phosphorylation (activation) of FAK at Tyr397 in LECs. Apigenin and luteolin prevented MMP1-induced FAK activation, but not constitutive FAK phosphorylation. Luteolin, unlike apigenin, inhibited MMP1-induced Ca2+ release. Free intracellular Ca2+ is a central signal amplifier triggering LEC retraction through activation of the mobility protein MLC2, thereby enhancing intravasation. FAK activity and Ca2+ levels did not correlate. This implicates that the pro intravasative contribution of FAK and of Ca2+ release in LECs was independent of each other and explains the better anti-intravasative effects of luteolin in vitro. In specific formulations, flavonoid concentrations causing significant anti-intravasative effects, can certainly be achieved in vivo. As the therapeutic strategy has to be based on permanent flavonoid treatment both the beneficial and adverse effects have to be investigated in future studies. PMID- 29593543 TI - The Trace Amine-Associated Receptor 1 Agonist 3-Iodothyronamine Induces Biased Signaling at the Serotonin 1b Receptor. AB - Trace amine-associated receptors (TAARs) belong to the class A G-protein-coupled receptors (GPCR) and are evolutionary related to aminergic receptors. TAARs have been identified to mediate effects of trace amines. TAAR1 signaling is mainly mediated via activation of the Gs/adenylyl cyclase pathway. In addition to classical trace amines, TAAR1 can also be activated by the thyroid hormone derivative 3-iodothyronamine (3-T1AM). Pharmacological doses of 3-T1AM induced metabolic and anapyrexic effects, which might be centrally mediated in the hypothalamus in rodents. However, the observed anapyrexic effect of 3-T1AM persists in Taar1 knock-out mice which raises the question whether further GPCRs are potential targets for 3-T1AM and mediate the observed physiological effect. Anapyrexia has been observed to be related to action on aminergic receptors such as the serotonin receptor 1b (5-HT1b). This receptor primarily activates the Gi/o mediated pathway and PLC signaling through the Gbetagamma of Gi/o. Since the expression profiles of TAAR1 and 5-HT1b overlap, we questioned whether 3-T1AM may activate 5-HT1b. Finally, we also evaluated heteromerization between these two GPCRs and tested signaling under co-expressed conditions. In this study, we showed, that 3-T1AM can induce Gi/o signaling through 5-HT1b in a concentration of 10 MUM. Strikingly, at 5-HT1b the ligand 3-T1AM only activates the Gi/o mediated reduction of cAMP accumulation, but not PLC activation. Co-stimulation of 5-HT1b by both ligands did not lead to additive or synergistic signaling effects. In addition, we confirmed the capacity for heteromerization between TAAR1 and 5-HT1b. Under co-expression of TAAR1 and HTR1b, 3-T1AM action is only mediated via TAAR1 and activation of 5-HT1b is abrogated. In conclusion, we found evidence for 5-HT1b as a new receptor target for 3-T1AM, albeit with a different signaling effect than the endogenous ligand. Altogether, this indicates a complex interrelation of signaling effects between the investigated GPCRs and respective ligands. PMID- 29593544 TI - The Influence of Shuttle-Shape Emodin Nanoparticles on the Streptococcus suis Biofilm. AB - Biofilm is one of the most important physiological protective barriers of the Streptococcus suis (S. suis), and it is also one of the primary causes of hindrance to drug infiltration, reduction of bactericidal effects, and the development of antibiotic resistance. In order to intervene or eliminate S. suis biofilm, shuttle-shape emodin-loaded nanoparticles were developed in our study. The emodin nanoparticles were prepared by emodin and gelatin-cyclodextrin which was synthesized as drug carrier, and the nanoparticles were 174 nm in size, -4.64 mv in zeta potential, and exhibited a sustained emodin release. Moreover, the delivery kinetics of nanoparticles were also explored in our study. The confocal laser scanning microscopy and colony forming unit enumeration experiment indicated that nanoparticles could increase drug infiltration and uptake by biofilm. The flow cytometry system analysis showed that nanoparticles could be up taken by 99% of the bacteria cells. TCP assay and scanning electron microscopy showed that the nanoparticles had better effect on biofilm inhibition and elimination when compared with emodin solution. These results revealed that the emodin nanoparticles had a better therapeutic effect on the S. suis biofilm in vitro. PMID- 29593545 TI - The Cytochrome P450-Mediated Metabolism Alternation of Four Effective Lignans From Schisandra chinensis in Carbon Tetrachloride-Intoxicated Rats and Patients With Advanced Hepatocellular Carcinoma. AB - It is highly valuable to study the pharmacokinetics of herbal components under the pathological condition of liver dysfunction for safe and rational use of herbal medicines. In this study, the pharmacokinetic profiles of four effective lignans from Schisandra chinensis (SC), schisandrin, schisantherin A, deoxyshisandrin and gamma-schisandrin, were investigated in carbon tetrachloride (CCl4)-intoxicated rats. The metabolism of the four lignans was also studied using microsomes from patients with advanced hepatocellular carcinoma. In situ intestinal and hepatic perfusions were conducted to clarify the contributions from impairments of gut and liver on the pharmacokinetics of the four schisandra lignans in CCl4-intoxicated rats. The metabolism in rat and human liver microsomes and transport in Caco-2 monolayer cell model were studied to reveal the key factors for the in vivo disposition of the four lignans. When SC alcoholic extract was orally administrated to CCl4-intoxicated rat for a short term (4 days), the pharmacokinetics of four active SC lignans was significantly changed while its hepatotherapeutic effect was not obviously observed. The plasma concentrations of the four schisandra lignans were dramatically elevated compared with the control. The Cmax, AUC and MRT were all increased or prolonged significantly while parameter CLz/F was obviously reduced in rat pretreated with CCl4. In hepatic perfusion study and liver microsomes incubation, it was found that the hepatic metabolism of the four lignans was markedly decreased mainly due to the activity reduction of multiple CYP450 isoenzymes involved the metabolism, which, eventually, might lead to the alternation of their pharmacokinetic profiles in CCl4-intoxicated rats or patients with advanced hepatocellular carcinoma. The pharmacokinetic studies of SC components in pathological situation of liver dysfunction are expected to provide useful data for rational and safe application of SC preparations in clinic or further pharmacological and toxicological research.

Nelson]. AB - Various parts of sea buckthorn [Elaeagnus rhamnoides (L.) A. Nelson], particularly the berries, known also as seaberries, or Siberian pineapples, are characterized by a unique composition of bioactive compounds: phenolic compounds, vitamins (especially vitamin C), unsaturated fatty acids, and phytosterols such as beta-sitosterol. These berries, together with the juices, jams, and oils made from them, have a range of beneficial antioxidant, anti-inflammatory, and anticancer effects. This short review discusses whether sea buckthorn may represent a "golden mean" for the treatment of cancers: It has anti-proliferation properties and can induce apoptosis and stimulate the immune system, and sea buckthorn oil counteracts many side effects of chemotherapy by restoring kidney and liver function, increasing appetite, and keeping patients in general good health. Although the anticancer activity of sea buckthorn has been confirmed by many in vitro and animal in vivo studies, the treatment and prophylactic doses for humans are unknown. Therefore, greater attention should be paid to the development of well-controlled and high-quality clinical experiments in this area. PMID- 29593548 TI - Impact of Nitric Oxide Bioavailability on the Progressive Cerebral and Peripheral Circulatory Impairments During Aging and Alzheimer's Disease. AB - Advanced aging, vascular dysfunction, and nitric oxide (NO) bioavailability are recognized risk factors for Alzheimer's disease (AD). However, the contribution of AD, per se, to this putative pathophysiological mechanism is still unclear. To better answer this point, we quantified cortical perfusion with arterial spin labeling (PVC-CBF), measured ultrasound internal carotid (ICA), and femoral (FA) artery blood flow in a group of patients with similar age (~78 years) but different cognitive impairment (i.e., mild cognitive impairment MCI, mild AD-AD1, moderate AD-AD2, and severe AD-AD3) and compared them to young and healthy old (aged-matched) controls. NO-metabolites and passive leg-movement (PLM) induced hyperemia were used to assess systemic vascular function. Ninety-eight individuals were recruited for this study. PVC-CBF, ICA, and FA blood flow were markedly (range of 9-17%) and significantly (all p < 0.05) reduced across the spectrum from YG to OLD, MCI, AD1, AD2, AD3 subjects. Similarly, plasma level of nitrates and the values of PLM were significantly reduced (range of 8-26%; p < 0.05) among the six groups. Significant correlations were retrieved between plasma nitrates, PLM and PVC-CBF, CA, and FA blood flow. This integrative and comprehensive approach to vascular changes in aging and AD showed progressive changes in NO bioavailability and cortical, extracranial, and peripheral circulation in patients with AD and suggested that they are directly associated with AD and not to aging. Moreover, these results suggest that AD-related impairments of circulation are progressive and not confined to the brain. The link between cardiovascular and the central nervous systems degenerative processes in patients at different severity of AD is likely related to the depletion of NO. PMID- 29593549 TI - Functional Polarity of Microvascular Brain Endothelial Cells Supported by Neurovascular Unit Computational Model of Large Neutral Amino Acid Homeostasis. AB - The homeostatic regulation of large neutral amino acid (LNAA) concentration in the brain interstitial fluid (ISF) is essential for proper brain function. LNAA passage into the brain is primarily mediated by the complex and dynamic interactions between various solute carrier (SLC) transporters expressed in the neurovascular unit (NVU), among which SLC7A5/LAT1 is considered to be the major contributor in microvascular brain endothelial cells (MBEC). The LAT1-mediated trans-endothelial transport of LNAAs, however, could not be characterized precisely by available in vitro and in vivo standard methods so far. To circumvent these limitations, we have incorporated published in vivo data of rat brain into a robust computational model of NVU-LNAA homeostasis, allowing us to evaluate hypotheses concerning LAT1-mediated trans-endothelial transport of LNAAs across the blood brain barrier (BBB). We show that accounting for functional polarity of MBECs with either asymmetric LAT1 distribution between membranes and/or intrinsic LAT1 asymmetry with low intraendothelial binding affinity is required to reproduce the experimentally measured brain ISF response to intraperitoneal (IP) L-tyrosine and L-phenylalanine injection. On the basis of these findings, we have also investigated the effect of IP administrated L tyrosine and L-phenylalanine on the dynamics of LNAAs in MBECs, astrocytes and neurons. Finally, the computational model was shown to explain the trans stimulation of LNAA uptake across the BBB observed upon ISF perfusion with a competitive LAT1 inhibitor. PMID- 29593550 TI - Naltrexone Reverses Ethanol Preference and Protein Kinase C Activation in Drosophila melanogaster. AB - Alcohol use disorder (AUD) is a major health, social and economic problem for which there are few effective treatments. The opiate antagonist naltrexone is currently prescribed clinically with mixed success. We have used naltrexone in an established behavioral assay (CAFE) in Drosophila melanogaster that measures the flies' preference for ethanol-containing food. We have confirmed that Drosophila exposed to ethanol develop a preference toward this drug and we demonstrate that naltrexone, in a dose dependant manner, reverses the ethanol-induced ethanol preference. This effect is not permanent, as preference for alcohol returns after discontinuing naltrexone. Additionally, naltrexone reduced the alcohol-induced increase in protein kinase C activity. These findings are of interest because they confirm that Drosophila is a useful model for studying human responses to addictive drugs. Additionally because of the lack of a closely conserved opiate system in insects, our results could either indicate that a functionally related system does exist in insects or that in insects, and potentially also in mammals, naltrexone binds to alternative sites. Identifying such sites could lead to improved treatment strategies for AUD. PMID- 29593551 TI - Retinal Vessel Diameters and Physical Activity in Patients With Mild to Moderate Rheumatic Disease Without Cardiovascular Comorbidities. AB - Objectives: Low-grade systemic inflammation is responsible for atherosclerotic lesions in patients with rheumatic diseases. Vascular dysfunction is a precursor of atherosclerosis and can be improved by physical activity (PA). Our aim was to asses micro- and macrovascular function as well as PA and cardiorespiratory fitness (CRF) in patients with rheumatic diseases in the absence of cardiovascular (CV) comorbidities compared to controls. Methods: Fifty-one patients without CV comorbidities were compared to 35 controls. Retinal microvascular diameters were assessed using a Retinal Vessel Analyzer. Arterial stiffness (AST) was measured by applanation tonometry. CRF was assessed as peak oxygen consumption and PA was assessed with a questionnaire. Results: Retinal venular diameters were significantly wider in patients [median 221 MUm (interquartile range (IQR) 211, 231)] compared to controls [median 215 MUm (IQR 196, 223); p = 0.01]. One hour increase of PA per week led to a venular constriction of -0.56 MUm (95%CI -1.09, -0.03; p = 0.04). In our patients with low disease activity (median DAS28 1.9; median BASDAI 2.8), no differences in AST were evident compared to controls. The association of PA and CRF with AST was not independent of blood pressure. Conclusions: Patients with rheumatic disease and mild-to-moderate disease activity show an impairment of the retinal microvasculature but not of large artery stiffness. Retinal vessel analysis seems to be a sensitive biomarker to unmask vascular impairments even in the absence of classic CV risk factors. PA may have the potential to counteract the development of small artery disease at early stages of rheumatic disease. PMID- 29593552 TI - KV4.3 Expression Modulates NaV1.5 Sodium Current. AB - In cardiomyocytes, the voltage-gated transient outward potassium current (Ito) is responsible for the phase-1 repolarization of the action potential (AP). Gain-of function mutations in KCND3, the gene encoding the Ito carrying KV4.3 channel, have been associated with Brugada syndrome (BrS). While the role of Ito in the pro-arrhythmic mechanism of BrS has been debated, recent studies have suggested that an increased Ito may directly affect cardiac conduction. However, the effects of an increased Ito on AP upstroke velocity or sodium current at the cellular level remain unknown. We here investigated the consequences of KV4.3 overexpression on NaV1.5 current and consequent sodium channel availability. We found that overexpression of KV4.3 protein in HEK293 cells stably expressing NaV1.5 (HEK293-NaV1.5 cells) significantly reduced NaV1.5 current density without affecting its kinetic properties. In addition, KV4.3 overexpression decreased AP upstroke velocity in HEK293-NaV1.5 cells, as measured with the alternating voltage/current clamp technique. These effects of KV4.3 could not be explained by alterations in total NaV1.5 protein expression. Using computer simulations employing a multicellular in silico model, we furthermore demonstrate that the experimentally observed increase in KV4.3 current and concurrent decrease in NaV1.5 current may result in a loss of conduction, underlining the potential functional relevance of our findings. This study gives the first proof of concept that KV4.3 directly impacts on NaV1.5 current. Future studies employing appropriate disease models should explore the potential electrophysiological implications in (patho)physiological conditions, including BrS associated with KCND3 gain-of-function mutations. PMID- 29593553 TI - High-Resolution X-Ray Tomography: A 3D Exploration Into the Skeletal Architecture in Mouse Models Submitted to Microgravity Constraints. AB - Bone remodeling process consists in a slow building phase and in faster resorption with the objective to maintain a functional skeleton locomotion to counteract the Earth gravity. Thus, during spaceflights, the skeleton does not act against gravity, with a rapid decrease of bone mass and density, favoring bone fracture. Several studies approached the problem by imaging the bone architecture and density of cosmonauts returned by the different spaceflights. However, the weaknesses of the previously reported studies was two-fold: on the one hand the research suffered the small statistical sample size of almost all human spaceflight studies, on the other the results were not fully reliable, mainly due to the fact that the observed bone structures were small compared with the spatial resolution of the available imaging devices. The recent advances in high-resolution X-ray tomography have stimulated the study of weight-bearing skeletal sites by novel approaches, mainly based on the use of the mouse and its various strains as an animal model, and sometimes taking advantage of the synchrotron radiation support to approach studies of 3D bone architecture and mineralization degree mapping at different hierarchical levels. Here we report the first, to our knowledge, systematic review of the recent advances in studying the skeletal bone architecture by high-resolution X-ray tomography after submission of mice models to microgravity constrains.

AB - Aging is a complex, multifactorial process characterized by the accumulation of deleterious effects, including biochemical adaptations of the extracellular matrix (ECM). The purpose of this study was to investigate the effects of 12 weeks of resistance training (RT) on metalloproteinase 2 (MMP-2) activity in skeletal muscles and, MMP-2 and MMP-9 activity in the blood circulation of young and old rats. Twenty-eight Wistar rats were randomly divided into four groups (n = 7 per group): young sedentary (YS); young trained (YT), old sedentary (OS), and old trained (OT). The stair climbing RT consisted of one training session every 2 other day, with 8-12 dynamic movements per climb. The animals were euthanized 48 h after the end of the experimental period. MMP-2 and MMP-9 activity was measured by zymography. There was higher active MMP-2 activity in the lateral gastrocnemius and flexor digitorum profundus muscles in the OT group when compared to the OS, YS, and YT groups (p <= 0.001). Moreover, there was higher active MMP-2 activity in the medial gastrocnemius muscle in the OT group when compared to the YS and YT groups (p <= 0.001). The YS group presented lower active MMP-2 activity in the soleus muscle than the YT, OS, OT groups (p <= 0.001). With respect to active MMP-2/9 activity in the bloodstream, the OT group displayed significantly reduced activity (p <= 0.001) when compared to YS and YT groups. In conclusion, RT up-regulates MMP-2 activity in aging muscles, while down-regulating MMP-2 and MMP-9 in the blood circulation, suggesting that it may be a useful tool for the maintenance of ECM remodeling.

AB - Objective: Ileal transposition (IT) surgery has been reported to improve glucose and lipid metabolism, and fibroblast growth factor 21 (FGF21) is a powerful metabolic regulator. In the present study, we aimed to investigate the effects of IT surgery on metabolism and its possible relationship with the FGF21 signaling pathway in diabetic Goto-Kakizaki (GK) rats. Methods: Ten-week-old male GK rats were subjected to IT surgery with translocation of a 10 cm ileal segment to the proximal jejunum (IT group) or sham surgery without the ileum transposition (Sham IT group). Rats in the no surgery group did not receive any surgical intervention. Six weeks later, body weight, fat mass, fasting blood glucose (FBG), and serum levels of FGF21 and leptin were measured. The expression of the FGF21 signaling pathway and white adipose tissue (WAT) browning-related genes in the WAT and liver were evaluated by real-time reverse transcription polymerase chain reaction (RT-qPCR) and western blot. Results: IT surgery significantly decreased the body weights and FBG levels and increased the insulin sensitivity of GK rats. The total WAT mass of the IT rats showed a 41.5% reduction compared with the Sham-IT rats, and serum levels of FGF21 and leptin of the IT rats decreased by 26.3 and 61.7%, respectively (all P < 0.05). The mRNA levels of fibroblast growth factor receptor 1 (FGFR1) and its co-receptor beta klotho (KLB) in the perirenal WAT (pWAT) of the IT rats were 1.4- and 2.4-fold that of the Sham-IT rats, respectively, and the FGFR1 protein levels were 1.7-fold of the Sham-IT rats (all P < 0.05). In accordance with the pWAT, the protein levels of FGFR1 and KLB in the epididymal WAT (eWAT) of the IT rats notably increased to 3.0- and 3.9-fold of the Sham-IT rats (P < 0.05). Furthermore, uncoupling protein 1 (UCP1) protein levels in the eWAT and pWAT of the IT rats also increased to 2.2 and 2.3-fold of the Sham-IT rats (P < 0.05). However, the protein levels of FGFR1 and KLB in the subcutaneous WAT (sWAT) of the IT rats decreased by 34.4 and 72.1%, respectively, compared with the Sham-IT rats (P < 0.05). In addition, the protein levels of FGF21 and KLB in the livers of IT rats were 3.9- and 2.3-fold of the Sham-IT rats (all P < 0.05). Conclusions: IT surgery significantly decreased fat mass and improved glucose metabolism in diabetic GK rats. These beneficial roles of IT surgery were probably associated with its stimulatory action on the expression of FGFR1 and KLB in both the eWAT and the pWAT, thereby promoting UCP1 expression in these tissues. PMID- 29593556 TI - Hypoglycemia: Role of Hypothalamic Glucose-Inhibited (GI) Neurons in Detection and Correction. AB - Hypoglycemia is a profound threat to the brain since glucose is its primary fuel. As a result, glucose sensors are widely located in the central nervous system and periphery. In this perspective we will focus on the role of hypothalamic glucose inhibited (GI) neurons in sensing and correcting hypoglycemia. In particular, we will discuss GI neurons in the ventromedial hypothalamus (VMH) which express neuronal nitric oxide synthase (nNOS) and in the perifornical hypothalamus (PFH) which express orexin. The ability of VMH nNOS-GI neurons to depolarize in low glucose closely parallels the hormonal response to hypoglycemia which stimulates gluconeogenesis. We have found that nitric oxide (NO) production in low glucose is dependent on oxidative status. In this perspective we will discuss the potential relevance of our work showing that enhancing the glutathione antioxidant system prevents hypoglycemia associated autonomic failure (HAAF) in non-diabetic rats whereas VMH overexpression of the thioredoxin antioxidant system restores hypoglycemia counterregulation in rats with type 1 diabetes.We will also address the potential role of the orexin-GI neurons in the arousal response needed for hypoglycemia awareness which leads to behavioral correction (e.g., food intake, glucose administration). The potential relationship between the hypothalamic sensors and the neurocircuitry in the hindbrain and portal mesenteric vein which is critical for hypoglycemia correction will then be discussed. PMID- 29593557 TI - 3,5-Diiodo-L-Thyronine Affects Structural and Metabolic Features of Skeletal Muscle Mitochondria in High-Fat-Diet Fed Rats Producing a Co-adaptation to the Glycolytic Fiber Phenotype. AB - Hyperlipidemic state-associated perturbations in the network of factors controlling mitochondrial functions, i. e., morphogenesis machinery and metabolic sensor proteins, produce metabolic inflexibility, insulin resistance and reduced oxidative capacity in skeletal muscle. Moreover, intramyocellular lipid (IMCL) accumulation leads to tissue damage and inflammation. The administration of the naturally occurring metabolite 3,5-diiodo-L-thyronine (T2) with thyromimetic actions to high fat diet (HFD)-fed rats exerts a systemic hypolipidemic effect, which produces a lack of IMCL accumulation, a shift toward glycolytic fibers and amelioration of insulin sensitivity in gastrocnemius muscle. In this study, an integrated approach combining large-scale expression profile and functional analyses was used to characterize the response of skeletal muscle mitochondria to T2 during a HFD regimen. Long-term T2 administration to HDF rats induced a glycolytic phenotype of gastrocnemius muscle as well as an adaptation of mitochondria to the fiber type, with a decreased representation of enzymes involved in mitochondrial oxidative metabolism. At the same time, T2 stimulated the activity of individual respiratory complex I, IV, and V. Moreover, T2 prevented the HFD-associated increase in the expression of peroxisome proliferative activated receptor gamma coactivator-1alpha and dynamin-1-like protein as well as mitochondrial morphological aberrations, favoring the appearance of tubular and tethered organelles in the intermyofibrillar regions. Remarkably, T2 reverted the HDF-associated expression pattern of proinflammatory factors, such as p65 subunit of NF-kB, and increased the fiber-specific immunoreactivity of adipose differentiation-related protein in lipid droplets. All together, these results further support a role of T2 in counteracting in vivo some of the HFD-induced impairment in structural/metabolic features of skeletal muscle by impacting the mitochondrial phenotype. PMID- 29593558 TI - An Individualized, Perception-Based Protocol to Investigate Human Physiological Responses to Cooling. AB - Cold exposure, a known stimulant of the thermogenic effects of brown adipose tissue (BAT), is the most widely used method to study BAT physiology in adult humans. Recently, individualized cooling has been recommended to standardize the physiological cold stress applied across participants, but critical experimental details remain unclear. The purpose of this work was to develop a detailed methodology for an individualized, perception-based protocol to investigate human physiological responses to cooling. Participants were wrapped in two water circulating blankets and fitted with skin temperature probes to estimate BAT activity and peripheral vasoconstriction. We created a thermoesthesia graphical user interface (tGUI) to continuously record the subject's perception of cooling and shivering status during the cooling protocol. The protocol began with a 15 min thermoneutral phase followed by a series of 10 min cooling phases and concluded when sustained shivering (>1 min duration) occurred. Researchers used perception of cooling feedback (tGUI ratings) to manually adjust and personalize the water temperature at each cooling phase. Blanket water temperatures were recorded continuously during the protocol. Twelve volunteers (ages: 26.2 +/- 1.4 years; 25% female) completed a feasibility study to evaluate the proposed protocol. Water temperature, perception of cooling, and shivering varied considerably across participants in response to cooling. Mean clavicle skin temperature, a surrogate measure of BAT activity, decreased (-0.99 degrees C, 95% CI: -1.7 to -0.25 degrees C, P = 0.16) after the cooling protocol, but an increase in supraclavicular skin temperature was observed in 4 participants. A strong positive correlation was also found between thermoesthesia and peripheral vasoconstriction (rho = 0.84, P < 0.001). The proposed individualized, perception based protocol therefore has potential to investigate the physiological responses to cold stress applied across populations with varying age, sex, body composition, and cold sensitivity characteristics. PMID- 29593559 TI - Ghrelin Pre-treatment Attenuates Local Oxidative Stress and End Organ Damage During Cardiopulmonary Bypass in Anesthetized Rats. AB - Cardiopulmonary bypass (CPB) induced systemic inflammation significantly contributes to the development of postoperative complications, including respiratory failure, myocardial, renal and neurological dysfunction and ultimately can lead to failure of multiple organs. Ghrelin is a small endogenous peptide with wide ranging physiological effects on metabolism and cardiovascular regulation. Herein, we investigated the protective effects of ghrelin against CPB induced inflammatory reactions, oxidative stress and acute organ damage. Adult male Sprague Dawley rats randomly received vehicle (n = 5) or a bolus of ghrelin (150 MUg/kg, sc, n = 5) and were subjected to CPB for 4 h (protocol 1). In separate rats, ghrelin pre-treatment (protocol 2) was compared to two doses of ghrelin (protocol 3) before and after CPB for 2 h followed by recovery for 2 h. Blood samples were taken prior to CPB, and following CPB at 2 h and 4 h. Organ nitrosative stress (3-nitrotyrosine) was measured by Western blotting. CPB induced leukocytosis with increased plasma levels of tumor necrosis factor-alpha and interleukin-6 indicating a potent inflammatory response. Ghrelin treatment significantly reduced plasma organ damage markers (lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase) and protein levels of 3 nitrotyrosine, particularly in the brain, lung and liver, but only partly suppressed inflammatory cell invasion and did not reduce proinflammatory cytokine production. Ghrelin partially attenuated the CPB-induced elevation of epinephrine and to a lesser extent norepinephrine when compared to the CPB saline group, while dopamine levels were completely suppressed. Ghrelin treatment sustained plasma levels of reduced glutathione and decreased glutathione disulphide when compared to CPB saline rats. These results suggest that even though ghrelin only partially inhibited the large CPB induced increase in catecholamines and organ macrophage infiltration, it reduced oxidative stress and subsequent cell damage. Pre-treatment with ghrelin might provide an effective adjunct therapy for preventing widespread CPB induced organ injury. PMID- 29593560 TI - Intestinal Metagenomes and Metabolomes in Healthy Young Males: Inactivity and Hypoxia Generated Negative Physiological Symptoms Precede Microbial Dysbiosis. AB - We explored the metagenomic, metabolomic and trace metal makeup of intestinal microbiota and environment in healthy male participants during the run-in (5 day) and the following three 21-day interventions: normoxic bedrest (NBR), hypoxic bedrest (HBR) and hypoxic ambulation (HAmb) which were carried out within a controlled laboratory environment (circadian rhythm, fluid and dietary intakes, microbial bioburden, oxygen level, exercise). The fraction of inspired O2 (FiO2) and partial pressure of inspired O2 (PiO2) were 0.209 and 133.1 +/- 0.3 mmHg for the NBR and 0.141 +/- 0.004 and 90.0 +/- 0.4 mmHg (~4,000 m simulated altitude) for HBR and HAmb interventions, respectively. Shotgun metagenomes were analyzed at various taxonomic and functional levels, 1H- and 13C -metabolomes were processed using standard quantitative and human expert approaches, whereas metals were assessed using X-ray fluorescence spectrometry. Inactivity and hypoxia resulted in a significant increase in the genus Bacteroides in HBR, in genes coding for proteins involved in iron acquisition and metabolism, cell wall, capsule, virulence, defense and mucin degradation, such as beta-galactosidase (EC3.2.1.23), alpha-L-fucosidase (EC3.2.1.51), Sialidase (EC3.2.1.18), and alpha N-acetylglucosaminidase (EC3.2.1.50). In contrast, the microbial metabolomes, intestinal element and metal profiles, the diversity of bacterial, archaeal and fungal microbial communities were not significantly affected. The observed progressive decrease in defecation frequency and concomitant increase in the electrical conductivity (EC) preceded or took place in absence of significant changes at the taxonomic, functional gene, metabolome and intestinal metal profile levels. The fact that the genus Bacteroides and proteins involved in iron acquisition and metabolism, cell wall, capsule, virulence and mucin degradation were enriched at the end of HBR suggest that both constipation and EC decreased intestinal metal availability leading to modified expression of co-regulated genes in Bacteroides genomes. Bayesian network analysis was used to derive the first hierarchical model of initial inactivity mediated deconditioning steps over time. The PlanHab wash-out period corresponded to a profound life-style change (i.e., reintroduction of exercise) that resulted in stepwise amelioration of the negative physiological symptoms, indicating that exercise apparently prevented the crosstalk between the microbial physiology, mucin degradation and proinflammatory immune activities in the host. PMID- 29593561 TI - Reciprocal Interactions of Mitochondria and the Neuroimmunoendocrine System in Neurodegenerative Disorders: An Important Role for Melatonin Regulation. AB - Structural and functional alterations of mitochondria are intimately linked to a wide array of medical conditions. Many factors are involved in the regulation of mitochondrial function, including cytokines, chaperones, chemokines, neurosteroids, and ubiquitins. The role of diffusely located cells of the neuroendocrine system, including biogenic amines and peptide hormones, in the management of mitochondrial function, as well as the role of altered mitochondrial function in the regulation of these cells and system, is an area of intense investigation. The current article looks at the interactions among the cells of the neuronal-glia, immune and endocrine systems, namely the diffuse neuroimmunoendocrine system (DNIES), and how DNIES interacts with mitochondrial function. Whilst changes in DNIES can impact on mitochondrial function, local, and systemic alterations in mitochondrial function can alter the component systems of DNIES and their interactions. This has etiological, course, and treatment implications for a wide range of medical conditions, including neurodegenerative disorders. Available data on the role of melatonin in these interactions, at cellular and system levels, are reviewed, with directions for future research indicated. PMID- 29593563 TI - Whole-Body Vibrations Associated With Alpine Skiing: A Risk Factor for Low Back Pain? AB - Alpine skiing, both recreational and competitive, is associated with high rates of injury. Numerous studies have shown that occupational exposure to whole-body vibrations is strongly related to lower back pain and some suggest that, in particular, vibrations of lower frequencies could lead to overuse injuries of the back in connection with alpine ski racing. However, it is not yet known which forms of skiing involve stronger vibrations and whether these exceed safety thresholds set by existing standards and directives. Therefore, this study was designed to examine whole-body vibrations connected with different types of skiing and the associated potential risk of developing low back pain. Eight highly skilled ski instructors, all former competitive ski racers and equipped with five accelerometers and a Global Satellite Navigation System to measure vibrations and speed, respectively, performed six different forms of skiing: straight running, plowing, snow-plow swinging, basic swinging, short swinging, and carved turns. To estimate exposure to periodic, random and transient vibrations the power spectrum density (PSD) and standard ISO 2631-1:1997 parameters [i.e., the weighted root-mean-square acceleration (RMS), crest factor, maximum transient vibration value and the fourth-power vibration dose value (VDV)] were calculated. Ground reaction forces were estimated from data provided by accelerometers attached to the pelvis. The major novel findings were that all of the forms of skiing tested produced whole-body vibrations, with highest PSD values of 1.5-8 Hz. Intensified PSD between 8.5 and 35 Hz was observed only when skidding was involved. The RMS values for 10 min of short swinging or carved turns, as well as all 10-min equivalent VDV values exceeded the limits set by European Directive 2002/44/EC for health and safety. Thus, whole-body vibrations, particularly in connection with high ground reaction forces, contribute to a high risk for low back pain among active alpine skiers. PMID- 29593562 TI - Toll-Like Receptors, Inflammation, and Calcific Aortic Valve Disease. AB - Inflammation, the primary response of innate immunity, is essential to initiate the calcification process underlying calcific aortic valve disease (CAVD), the most prevalent valvulopathy in Western countries. The pathogenesis of CAVD is multifactorial and includes inflammation, hemodynamic factors, fibrosis, and active calcification. In the development of CAVD, both innate and adaptive immune responses are activated, and accumulating evidences show the central role of inflammation in the initiation and propagation phases of the disease, being the function of Toll-like receptors (TLR) particularly relevant. These receptors act as sentinels of the innate immune system by recognizing pattern molecules from both pathogens and host-derived molecules released after tissue damage. TLR mediate inflammation via NF-kappaB routes within and beyond the immune system, and play a crucial role in the control of infection and the maintenance of tissue homeostasis. This review outlines the current notions about the association between TLR signaling and the ensuing development of inflammation and fibrocalcific remodeling in the pathogenesis of CAVD. Recent data provide new insights into the inflammatory and osteogenic responses underlying the disease and further support the hypothesis that inflammation plays a mechanistic role in the initiation and progression of CAVD. These findings make TLR signaling a potential target for therapeutic intervention in CAVD. PMID- 29593564 TI - Dynamic Action Potential Restitution Contributes to Mechanical Restitution in Right Ventricular Myocytes From Pulmonary Hypertensive Rats. AB - We investigated the steepened dynamic action potential duration (APD) restitution of rats with pulmonary artery hypertension (PAH) and right ventricular (RV) failure and tested whether the observed APD restitution properties were responsible for negative mechanical restitution in these myocytes. PAH and RV failure were provoked in male Wistar rats by a single injection of monocrotaline (MCT) and compared with saline-injected animals (CON). Action potentials were recorded from isolated RV myocytes at stimulation frequencies between 1 and 9 Hz. Action potential waveforms recorded at 1 Hz were used as voltage clamp profiles (action potential clamp) at stimulation frequencies between 1 and 7 Hz to evoke rate-dependent currents. Voltage clamp profiles mimicking typical CON and MCT APD restitution were applied and cell shortening simultaneously monitored. Compared with CON myocytes, MCT myocytes were hypertrophied; had less polarized diastolic membrane potentials; had action potentials that were triggered by decreased positive current density and shortened by decreased negative current density; APD was longer and APD restitution steeper. APD90 restitution was unchanged by exposure to the late Na+-channel blocker (5 MUM) ranolazine or the intracellular Ca2+ buffer BAPTA. Under AP clamp, stimulation frequency-dependent inward currents were smaller in MCT myocytes and were abolished by BAPTA. In MCT myocytes, increasing stimulation frequency decreased contraction amplitude when depolarization duration was shortened, to mimic APD restitution, but not when depolarization duration was maintained. We present new evidence that the membrane potential of PAH myocytes is less stable than normal myocytes, being more easily perturbed by external currents. These observations can explain increased susceptibility to arrhythmias. We also present novel evidence that negative APD restitution is at least in part responsible for the negative mechanical restitution in PAH myocytes. Thus, our study links electrical restitution remodeling to a defining mechanical characteristic of heart failure, the reduced ability to respond to an increase in demand. PMID- 29593565 TI - Aerobic Interval Training Prevents Age-Dependent Vulnerability to Atrial Fibrillation in Rodents. AB - Aims: Increasing age is the most important risk factor for atrial fibrillation (AF). Very high doses of exercise training might increase AF risk, while moderate levels seem to be protective. This study aimed to examine the effects of age on vulnerability to AF and whether long-term aerobic interval training (AIT) could modify these effects. Methods: Nine months old, male Sprague-Dawley rats were randomized to AIT for 16 weeks (old-ex) or to a sedentary control group (old sed), and compared to young sedentary males (young-sed). After the intervention, animals underwent echocardiography, testing of exercise capacity (VO2max), and electrophysiology with AF induction before ex vivo electrophysiology. Fibrosis quantification, immunohistochemistry and western blotting of atrial tissue were performed. Results: Sustained AF was induced in vivo in 4 of 11 old-sed animals, but none of the old-ex or young-sed rats (p = 0.006). VO2max was lower in old sed, while old-ex had comparable results to young-sed. Fibrosis was increased in old-sed (p = 0.006), with similar results in old-ex. There was a significantly slower atrial conduction in old-sed (p = 0.038), with an increase in old-ex (p = 0.027). Action potential duration was unaltered in old-sed, but prolonged in old ex (p = 0.036). There were no differences in amount of atrial connexin 43 between groups, but a lateralization in atrial cardiomyocytes of old-sed, with similar findings in old-ex. Conclusion: AF vulnerability was higher in old-sed animals, associated with increased atrial fibrosis, lateralization of connexin-43, and reduced atrial conduction velocity. AIT reduced the age-associated susceptibility to AF, possibly through increased conduction velocity and prolongation of action potentials. PMID- 29593566 TI - Real-Time Rotational Activity Detection in Atrial Fibrillation. AB - Rotational activations, or spiral waves, are one of the proposed mechanisms for atrial fibrillation (AF) maintenance. We present a system for assessing the presence of rotational activity from intracardiac electrograms (EGMs). Our system is able to operate in real-time with multi-electrode catheters of different topologies in contact with the atrial wall, and it is based on new local activation time (LAT) estimation and rotational activity detection methods. The EGM LAT estimation method is based on the identification of the highest sustained negative slope of unipolar signals. The method is implemented as a linear filter whose output is interpolated on a regular grid to match any catheter topology. Its operation is illustrated on selected signals and compared to the classical Hilbert-Transform-based phase analysis. After the estimation of the LAT on the regular grid, the detection of rotational activity in the atrium is done by a novel method based on the optical flow of the wavefront dynamics, and a rotation pattern match. The methods have been validated using in silico and real AF signals. PMID- 29593567 TI - Kisspeptin Receptor GPR54 Promotes Adipocyte Differentiation and Fat Accumulation in Mice. AB - GPR54, Kisspeptin-1 receptor (KISS1R), a member of rhodopsin family, plays a critical role in puberty development and has been proposed to be involved in regulation of energy metabolism. This study aims to explore the function of GPR54 in adipogenesis, lipid metabolism, and obesity in addition to its effect through hormones. Results showed that when fed a high-fat diet, the weight growth of castrated or ovariectomized Gpr54-/- mice was significantly slower than that of WT control, together with a lower triglyceride concentration. The ratio of white adipose tissue was lower, and average size of adipocytes was smaller in Gpr54-/- mice. Meanwhile, there were less adipose tissue macrophages (ATMs), especially pro-inflammatory macrophages. Expression of inflammatory related genes also indicated that inflammatory response caused by obesity was not as drastic in Gpr54-/- mice as in WT mice. Liver triglyceride in Gpr54-/- mice was reduced, especially in female mice. On the other hand, oil drop formation was accelerated when hepatocytes were stimulated by kisspeptin-10 (Kp-10). Primary mesenchymal stem cells (MSCs) of Gpr54-/- mice were less likely to differentiate into adipocytes. When stimulated by Kp-10, 3T3-L1 cell differentiation into adipocytes was accelerated and triglyceride synthesis was significantly promoted. These data indicated that GPR54 could affect obesity development by promoting adipocyte differentiation and triglyceride accumulation. To further elucidate the mechanism, genes related to lipid metabolism were analyzed. The expression of genes involved in lipid synthesis including PPARgamma, ACC1, ADIPO, and FAS was significantly changed in Gpr54-/- mice. Among them PPARgamma which also participate in adipocyte differentiation displayed a marked reduction. Moreover, phosphorylation of ERK, which involved in GPR54 signaling, was significantly decreased in Gpr54-/- mice, suggesting that GPR54 may promote lipid synthesis and obesity development by activating MAP kinase pathway. Therefore, in addition to the involvement in hormone regulation, our study demonstrated that GPR54 directly participates in obesity development by promoting adipocyte differentiation and fat accumulation. This provided evidence of involvement of GPR54 in lipid metabolism, and revealed new potentials for the identification and development of novel drug targets for metabolic diseases. PMID- 29593568 TI - Bisecting N-Acetylglucosamine Structures Inhibit Hypoxia-Induced Epithelial Mesenchymal Transition in Breast Cancer Cells. AB - The epithelial-mesenchymal transition (EMT) process plays a key role in many biological processes, including tissue fibrosis, metastatic diseases, and cancer progression. EMT can be induced by certain factors, notably hypoxia, in the tumor microenvironment. Aberrant levels of certain N-glycans is associated with cancer progression. We used an integrated strategy (mass spectrometry in combination with lectin microarray analysis) to elucidate aberrant glycosylation in a hypoxia induced EMT model using breast cancer cell lines MCF7 and MDA-MB-231. The model showed reduced levels of bisecting GlcNAc structures, and downregulated expression of the corresponding glycosyltransferase MGAT3. MGAT3 overexpression in MCF7 suppressed cell migration, proliferation, colony formation, expression of EMT markers, and AKT signaling pathway, whereas MGAT3 knockdown (shRNA silencing) had opposite effects. Our findings clearly demonstrate the functional role (and effects of dysregulation) of bisecting GlcNAc structures in hypoxia-induced EMT, and provide a useful basis for further detailed studies of physiological functions of these structures in breast cancer. PMID- 29593569 TI - Spatial mRNA Expression and Response to Fasting and Refeeding of Neutral Amino Acid Transporters slc6a18 and slc6a19a in the Intestinal Epithelium of Mozambique tilapia. AB - The mRNA expressions of the epithelial neutral amino acid transporters slc6a18 and slc6a19a in the five segments (HL, PMC, GL, DMC, and TS) of the intestine of Mozambique tilapia, and their responses to fasting and refeeding were investigated for a better understanding of the functional and nutritional characteristics of slc6a18 and slc6a19a. Although both slc6a18 and slc6a19a were expressed mainly in the intestine, these genes showed opposing spatial distributions along the intestine. The slc6a18 was mainly expressed in the middle (GL) and posterior (DMC and TS) intestines, while slc6a19a was specifically expressed in the anterior intestine (HL and PMC). Large decreases of amino acid concentrations from the HL to GL imply that amino acids are mainly absorbed before reaching the GL, suggesting an important role of slc6a19a in the absorption. Moreover, substantial amounts of some neutral amino acids with the isoelectric point close to 6 remain in the GL. These are most likely the remaining unabsorbed amino acids or those from of amino acid antiporters which release neutral amino acids in exchange for uptake of its substrates. These amino acids were diminished in the TS, suggesting active absorption in the posterior intestine. This suggests that slc6a18 is essential to complete the absorption of neutral amino acids. At fasting, significant downregulation of slc6a19a expression was observed from the initial up to day 2 and became stable from day 4 to day 14 in the HL and PMC suggesting that slc6a19a expression reflects nutritional condition in the intestinal lumen. Refeeding stimulates slc6a19a expression, although expressions did not exceed the initial level within 3 days after refeeding. The slc6a18 expression was decreased during fasting in the GL but no significant change was observed in the DMC. Only a transient decrease was observed at day 2 in the TS. Refeeding did not stimulate slc6a18 expression. Results in this study suggest that Slc6a18 and Slc6a19 have different roles in the intestine, and that both of these contribute to establish the efficient neutral amino acid absorption system in the tilapia. PMID- 29593570 TI - Distinct ECG Phenotypes Identified in Hypertrophic Cardiomyopathy Using Machine Learning Associate With Arrhythmic Risk Markers. AB - Aims: Ventricular arrhythmia triggers sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM), yet electrophysiological biomarkers are not used for risk stratification. Our aim was to identify distinct HCM phenotypes based on ECG computational analysis, and characterize differences in clinical risk factors and anatomical differences using cardiac magnetic resonance (CMR) imaging. Methods: High-fidelity 12-lead Holter ECGs from 85 HCM patients and 38 healthy volunteers were analyzed using mathematical modeling and computational clustering to identify phenotypic subgroups. Clinical features and the extent and distribution of hypertrophy assessed by CMR were evaluated in the subgroups. Results: QRS morphology alone was crucial to identify three HCM phenotypes with very distinct QRS patterns. Group 1 (n = 44) showed normal QRS morphology, Group 2 (n = 19) showed short R and deep S waves in V4, and Group 3 (n = 22) exhibited short R and long S waves in V4-6, and left QRS axis deviation. However, no differences in arrhythmic risk or distribution of hypertrophy were observed between these groups. Including T wave biomarkers in the clustering, four HCM phenotypes were identified: Group 1A (n = 20), with primary repolarization abnormalities showing normal QRS yet inverted T waves, Group 1B (n = 24), with normal QRS morphology and upright T waves, and Group 2 and Group 3 remaining as before, with upright T waves. Group 1A patients, with normal QRS and inverted T wave, showed increased HCM Risk-SCD scores (1A: 4.0%, 1B: 1.8%, 2: 2.1%, 3: 2.5%, p = 0.0001), and a predominance of coexisting septal and apical hypertrophy (p < 0.0001). HCM patients in Groups 2 and 3 exhibited predominantly septal hypertrophy (85 and 90%, respectively). Conclusion: HCM patients were classified in four subgroups with distinct ECG features. Patients with primary T wave inversion not secondary to QRS abnormalities had increased HCM Risk-SCD scores and coexisting septal and apical hypertrophy, suggesting that primary T wave inversion may increase SCD risk in HCM, rather than T wave inversion secondary to depolarization abnormalities. Computational ECG phenotyping provides insight into the underlying processes captured by the ECG and has the potential to be a novel and independent factor for risk stratification. PMID- 29593571 TI - Mechanistic Role of Reactive Oxygen Species and Therapeutic Potential of Antioxidants in Denervation- or Fasting-Induced Skeletal Muscle Atrophy. AB - Skeletal muscle atrophy occurs under various conditions, such as disuse, denervation, fasting, aging, and various diseases. Although the underlying molecular mechanisms are still not fully understood, skeletal muscle atrophy is closely associated with reactive oxygen species (ROS) overproduction. In this study, we aimed to investigate the involvement of ROS in skeletal muscle atrophy from the perspective of gene regulation, and further examine therapeutic effects of antioxidants on skeletal muscle atrophy. Microarray data showed that the gene expression of many positive regulators for ROS production were up-regulated and the gene expression of many negative regulators for ROS production were down regulated in mouse soleus muscle atrophied by denervation (sciatic nerve injury). The ROS level was significantly increased in denervated mouse soleus muscle or fasted C2C12 myotubes that had suffered from fasting (nutrient deprivation). These two muscle samples were then treated with N-acetyl-L-cysteine (NAC, a clinically used antioxidant) or pyrroloquinoline quinone (PQQ, a naturally occurring antioxidant), respectively. As compared to non-treatment, both NAC and PQQ treatment (1) reversed the increase in the ROS level in two muscle samples; (2) attenuated the reduction in the cross-sectional area (CSA) of denervated mouse muscle or in the diameter of fasted C2C12 myotube; (3) increased the myosin heavy chain (MHC) level and decreased the muscle atrophy F-box (MAFbx) and muscle specific RING finger-1 (MuRF-1) levels in two muscle samples. Collectively, these results suggested that an increased ROS level was, at least partly, responsible for denervation- or fasting-induced skeletal muscle atrophy, and antioxidants might resist the atrophic effect via ROS-related mechanisms. PMID- 29593572 TI - Identification of Exosomal miRNAs in Rats With Pulmonary Neutrophilic Inflammation Induced by Zinc Oxide Nanoparticles. AB - It has been previously shown that inhaled zinc oxide nanoparticles (ZnO-NPs) can modulate inflammation. MicroRNAs (miRNAs) enclosed in exosomes have been identified as an important signature for inflammatory responses. However, the role of exosomal miRNAs during pathogenic inflammation has not been investigated. Healthy rats were exposed to ZnO-NPs (41.7 nm; 2, 4, and 8 mg/kg) or saline (control) via oropharyngeal aspiration. ZnO-NPs induced significant increases in the serum levels of interleukin 8 (IL-8), interleukin-1 beta (IL-1beta), and tumor necrosis factor alpha (TNF-alpha), and elevated the number of cells and the percentage of neutrophils in the blood. Moreover, exposure to ZnO-NPs increased the levels of lactate dehydrogenase (LDH) activity and total protein in bronchoalveolar lavage fluid (BALF). Differential profiling of miRNAs in isolated serum exosomes revealed that 16 miRNAs were up-regulated and 7 down-regulated in ZnO-NP-treated rats compared with the controls. Functional and pathway analysis indicated that miRNAs may participate in inflammation directly and indirectly through protein and vesicle-mediated transport or regulation of IL-1, oxidative stress, apoptosis, and autophagy. These results suggest that miRNAs in serum exosomes are involved in pulmonary neutrophilic inflammation induced by ZnO-NPs.

AB - The prevalence of non-alcoholic fatty liver disease (NAFLD), which is developed from hepatic steatosis, is increasing worldwide. However, no specific drugs for NAFLD have been approved yet. To observe the effects of Rho, a fraction from Rhodiola crenulate, on non-alcoholic hepatic steatosis, three mouse models with characteristics of NAFLD were used including high-fat diet (HFD)-induced obesity (DIO) mice, KKAy mice, and HFD combined with tetracycline stimulated Model-T mice. Hepatic lipid accumulation was determined via histopathological analysis and/or hepatic TG determination. The responses to insulin were evaluated by insulin tolerance test (ITT), glucose tolerance test (GTT), and hyperinsulinemic euglycemic clamp, respectively. The pathways involved in hepatic lipid metabolism were observed via western-blot. Furthermore, the liver microcirculation was observed by inverted microscopy. The HPLC analysis indicated that the main components of Rho were flavan polymers. The results of histopathological analysis showed that Rho could ameliorate hepatic steatosis in DIO, KKAy, and Model-T hepatic steatosis mouse models, respectively. After Rho treatment in DIO mice, insulin resistance was improved with increasing glucose infusion rate (GIR) in hyperinsulinemic-euglycemic clamp, and decreasing areas under the blood glucose time curve (AUC) in both ITT and GTT; the pathways involved in fatty acid uptake and de novo lipogenesis were both down-regulated, respectively. However, the pathways involved in beta-oxidation and VLDL-export on hepatic steatosis were not changed significantly. The liver microcirculation disturbances were also improved by Rho in DIO mice. These results suggest that Rho is a lead nature product for hepatic steatosis treatment. The mechanism is related to enhancing insulin sensitivity, suppressing fatty acid uptake and inhibiting de novo lipogenesis in liver. PMID- 29593574 TI - The Use of Biophysical Flow Models in the Surgical Management of Patients Affected by Chronic Thromboembolic Pulmonary Hypertension. AB - Introduction: Chronic Thromboembolic Pulmonary Hypertension (CTEPH) results from progressive thrombotic occlusion of the pulmonary arteries. It is treated by surgical removal of the occlusion, with success rates depending on the degree of microvascular remodeling. Surgical eligibility is influenced by the contributions of both the thrombus occlusion and microvasculature remodeling to the overall vascular resistance. Assessing this is challenging due to the high inter individual variability in arterial morphology and physiology. We investigated the potential of patient-specific computational flow modeling to quantify pressure gradients in the pulmonary arteries of CTEPH patients to assist the decision making process for surgical eligibility. Methods: Detailed segmentations of the pulmonary arteries were created from postoperative chest Computed Tomography scans of three CTEPH patients. A focal stenosis was included in the original geometry to compare the pre- and post-surgical hemodynamics. Three-dimensional flow simulations were performed on each morphology to quantify velocity-dependent pressure changes using a finite element solver coupled to terminal 2-element Windkessel models. In addition to transient flow simulations, a parametric modeling approach based on constant flow simulations is also proposed as faster technique to estimate relative pressure drops through the proximal pulmonary vasculature. Results: An asymmetrical flow split between left and right pulmonary arteries was observed in the stenosed models. Removing the proximal obstruction resulted in a reduction of the right-left pressure imbalance of up to 18%. Changes were also observed in the wall shear stresses and flow topology, where vortices developed in the stenosed model while the non-stenosed retained a helical flow. The predicted pressure gradients from constant flow simulations were consistent with the ones measured in the transient flow simulations. Conclusion: This study provides a proof of concept that patient-specific computational modeling can be used as a noninvasive tool for assisting surgical decisions in CTEPH based on hemodynamics metrics. Our technique enables determination of the proximal relative pressure, which could subsequently be compared to the total pressure drop to determine the degree of distal and proximal vascular resistance. In the longer term this approach has the potential to form the basis for a more quantitative classification system of CTEPH types. PMID- 29593575 TI - Dai-Zong-Fang, A Traditional Chinese Herbal Formula, Ameliorates Insulin Resistance in db/db Mice. AB - Intricate health problems, such as insulin resistance (IR) and its associated diseases, call for multi-targeted therapies with few side effects. Based on traditional Chinese medicine (TCM), Dai-Zong-Fang (DZF) is an herbal formula mainly composed of Rhizoma Coptidis (Huanglian) and Fructus Aurantii Immaturus (Zhishi), of which berberine and naringin are the main constituents. Though DZF has been clinically used for treatment of IR and metabolic syndrome for decades, its mechanism in vivo remains unknown. In the present study, we observed that both DZF and metformin, the first-line drug for type 2 diabetes, ameliorated insulin resistance with significant improvement of oral glucose tolerance test (OGTT) and homeostasis model assessment of IR (HOMA-IR) level in diabetic C57BL/Ksj-Lepr db-/- (db/db) mice. Low-density lipoprotein cholesterol (LDL-C) and fatty acids (FAs) also decreased in the blood. Higher dose of DZF (1 g.kg-1), but not metformin (0.25 g.kg-1), alleviated hepatic steatosis with reduced liver weight and hepatic lipid accumulation and provided protection from hepatic injury with lower alanine aminotransferase and aspartate aminotransferase and increased hepatic superoxide dismutase activity in db/db mice. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) showed a decrease in FA synthase gene (Fasn) and an increase in FA oxidation gene Ppara expression. Western blot demonstrated that both DZF and metformin activated 5' AMP-activated protein kinase (AMPK) but inhibited Notch intracellular domain (NICD) and Hairy/enhancer-of-split 1 (Hes1) of Notch signaling pathway in the liver. DZF also dramatically improved the ultrastructure of skeletal muscles, AMPK phosphorylation, and GLUT4 translocation. DZF also promoted FA transport and oxidation with Cd36 and Cpt1b up-regulation in the skeletal muscle. In conclusion, DZF improves insulin sensitivity by reducing hepatic lipids through AMPK activation and Notch signal pathway inhibition and enhancing energy metabolism in the skeletal muscle via AMPK. This study provides insights into the treatment of complex conditions, such as IR, where TCM herbal formulas exert multipronged effects through correlating pathways. PMID- 29593577 TI - Predicting Medical Students' Current Attitudes Toward Psychiatry, Interest in Psychiatry, and Estimated Likelihood of Working in Psychiatry: A Cross-Sectional Study in Four European Countries. AB - Psychiatry as a medical discipline is becoming increasingly important due to the high and increasing worldwide burden associated with mental disorders. Surprisingly, however, there is a lack of young academics choosing psychiatry as a career. Previous evidence on medical students' perspectives is abundant but has methodological shortcomings. Therefore, by attempting to avoid previous shortcomings, we aimed to contribute to a better understanding of the predictors of the following three outcome variables: current medical students' attitudes toward psychiatry, interest in psychiatry, and estimated likelihood of working in psychiatry. The sample consisted of N = 1,356 medical students at 45 medical schools in Germany and Austria as well as regions of Switzerland and Hungary with a German language curriculum. We used snowball sampling via Facebook with a link to an online questionnaire as recruitment procedure. Snowball sampling is based on referrals made among people. This questionnaire included a German version of the Attitudes Toward Psychiatry Scale (ATP-30-G) and further variables related to outcomes and potential predictors in terms of sociodemography (e.g., gender) or medical training (e.g., curriculum-related experience with psychiatry). Data were analyzed by linear mixed models and further regression models. On average, students had a positive attitude to and high general interest in, but low professional preference for, psychiatry. A neutral attitude to psychiatry was partly related to the discipline itself, psychiatrists, or psychiatric patients. Female gender and previous experience with psychiatry, particularly curriculum related and personal experience, were important predictors of all outcomes. Students in the first years of medical training were more interested in pursuing psychiatry as a career. Furthermore, the country of the medical school was related to the outcomes. However, statistical models explained only a small proportion of variance. The findings indicate that particularly curriculum related experience is important for determining attitudes toward psychiatry, interest in the subject and self-predicted professional career choice. We therefore encourage the provision of opportunities for clinical experience by psychiatrists. However, further predictor variables need to be considered in future studies. PMID- 29593578 TI - Mental Disorder-The Need for an Accurate Definition. AB - There are several reasons why a definition for mental disorder is essential. Among these are not only reasons linked to psychiatry itself as a science (nosology, research) but also to ethical, legal, and financial issues. The first formal definition of mental disorder resulted from a deep conceptual analysis led by Robert Spitzer. It emerged to address several challenges that psychiatry faced at the time, namely to serve as the starting point for an atheoretical and evidence-based classification of mental disorders, to justify the removal of homosexuality from classifications, and to counter the arguments of antipsychiatry. This definition has been updated, with some conceptual changes that make it depart from the main assumptions of Spitzer's original definition. In this article, we intend to review the factors that substantiated the emergence of the first formal definition of mental disorder that based all its later versions. PMID- 29593576 TI - Vagus Nerve as Modulator of the Brain-Gut Axis in Psychiatric and Inflammatory Disorders. AB - The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate. It establishes one of the connections between the brain and the gastrointestinal tract and sends information about the state of the inner organs to the brain via afferent fibers. In this review article, we discuss various functions of the vagus nerve which make it an attractive target in treating psychiatric and gastrointestinal disorders. There is preliminary evidence that vagus nerve stimulation is a promising add-on treatment for treatment-refractory depression, posttraumatic stress disorder, and inflammatory bowel disease. Treatments that target the vagus nerve increase the vagal tone and inhibit cytokine production. Both are important mechanism of resiliency. The stimulation of vagal afferent fibers in the gut influences monoaminergic brain systems in the brain stem that play crucial roles in major psychiatric conditions, such as mood and anxiety disorders. In line, there is preliminary evidence for gut bacteria to have beneficial effect on mood and anxiety, partly by affecting the activity of the vagus nerve. Since, the vagal tone is correlated with capacity to regulate stress responses and can be influenced by breathing, its increase through meditation and yoga likely contribute to resilience and the mitigation of mood and anxiety symptoms.

PMID- 29593580 TI - Self-Reported Visual Perceptual Abnormalities Are Strongly Associated with Core Clinical Features in Psychotic Disorders. AB - Background: Past studies using the Bonn Scale for the Assessment of Basic Symptoms (hereafter, Bonn Scale) have shown that self-reported perceptual/cognitive disturbances reveal which persons have or will soon develop schizophrenia. Here, we focused specifically on the clinical value of self reported visual perceptual abnormalities (VPAs) since they are underexplored and have been associated with suicidal ideation, negative symptoms, and objective visual dysfunction. Method: Using the 17 Bonn Scale vision items, we cross sectionally investigated lifetime occurrence of VPAs in 21 first-episode psychosis and 22 chronic schizophrenia/schizoaffective disorder (SZ/SA) patients. Relationships were probed between VPAs and illness duration, symptom severity, current functioning, premorbid functioning, diagnosis, and age of onset. Results: Increased VPAs were associated with: earlier age of onset; more delusions, hallucinations, bizarre behavior, and depressive symptoms; and worse premorbid social functioning, especially in the childhood and early adolescent phases. SZ/SA participants endorsed more VPAs as compared to those with schizophreniform or psychotic disorder-NOS, especially in the perception of color, bodies, faces, object movement, and double/reversed vision. The range of self-reported VPAs was strikingly similar between first-episode and chronic patients and did not depend on the type or amount of antipsychotic medication. As a comparative benchmark, lifetime occurrence of visual hallucinations did not depend on diagnosis and was linked only to poor premorbid social functioning. Conclusion: A brief 17-item interview derived from the Bonn Scale is strongly associated with core clinical features in schizophrenia. VPAs hold promise for clarifying diagnosis, predicting outcome, and guiding neurocognitive investigations. PMID- 29593581 TI - Enhanced Amygdala-Striatal Functional Connectivity during the Processing of Cocaine Cues in Male Cocaine Users with a History of Childhood Trauma. AB - Background and aims: Childhood trauma is associated with increased levels of anxiety later in life, an increased risk for the development of substance use disorders, and neurodevelopmental abnormalities in the amygdala and frontostriatal circuitry. The aim of this study was to investigate the (neurobiological) link among childhood trauma, state anxiety, and amygdala frontostriatal activity in response to cocaine cues in regular cocaine users. Methods: In this study, we included 59 non-treatment seeking regular cocaine users and 58 non-drug using controls. Blood oxygenation level-dependent responses were measured using functional magnetic resonance imaging while subjects performed a cue reactivity paradigm with cocaine and neutral cues. Psychophysiological interaction analyses were applied to assess functional connectivity between the amygdala and other regions in the brain. Self-report questionnaires were used to measure childhood trauma, state anxiety, drug use, drug use severity, and craving. Results: Neural activation was increased during the presentation of cocaine cues, in a widespread network including the frontostriatal circuit and amygdala in cocaine users but not in controls. Functional coupling between the amygdala and medial prefrontal cortex was reduced in response to cocaine cues, in both cocaine users and controls, which was further diminished with increasing state anxiety. Importantly, amygdala-striatal connectivity was positively associated with childhood trauma in regular cocaine users, while there was a negative association in controls. At the behavioral level, state anxiety was positively associated with cocaine use severity and craving related to negative reinforcement. Conclusion: Childhood trauma is associated with enhanced amygdala-striatal connectivity during cocaine cue reactivity in regular cocaine users, which may contribute to increased habit behavior and poorer cognitive control. While we cannot draw conclusions on causality, this study provides novel information on how childhood trauma may contribute to the development and persistence of cocaine use disorder. PMID- 29593583 TI - Attachment to Parents As a Moderator in the Association between Sibling Bullying and Depression or Suicidal Ideation among Children and Adolescents. AB - Bullying is one of the most widespread phenomenon in childhood and adolescence. Interestingly, most research on bullying focuses on bullying at school and not on bullying among siblings at home. Sibling bullying is the most frequent form of repeated aggression that children experience in their lifetime. Furthermore, previous studies indicate that sibling bullying is associated with depression and self-harm behavior. However, the association between sibling bullying and suicidal ideation was never previously examined. Attachment to parents is one variable that can moderate the association between sibling bullying and depression/suicide ideation. To our knowledge, there is no existing study that examines the association between sibling bullying and attachment patterns. In addition, no previous study has examined the moderating role of attachment on the association between sibling bullying and depression or suicidal ideation among adolescents. The current study includes 279 Israeli students aged 10-17 (M = 13.5; SD = 1.98; 164, 58.8% females) who completed self-report questionnaires regarding school and sibling bullying, attachment to mother and father, depression, and suicidal ideation. The results indicated an association between bullying among siblings and school bullying. In addition, children and adolescents who were consistently involved in sibling bullying were at greater risk for depression and suicide ideation when compared to children and adolescents who were not involved in sibling bullying. A secure attachment to one's father (but not to one's mother) moderated the association between sibling bullying and depression/suicide ideation. It should be noted that when suicide ideation was examined above and beyond depression, attachment to one's father did not moderate the association between sibling bullying involvement and suicide ideation. This finding indicates that depression plays a central role in the association between sibling bullying and suicide ideation. These results suggest that sibling bullying is a risk factor for depressive symptoms and suicide ideation and that secure attachment to one's father may serve as a protective role. Future bullying prevention programs should include sibling bullying and encourage the increased availability of paternal emotional support. Other theoretical and applied implications for prevention of both sibling bullying and suicide are discussed. PMID- 29593582 TI - Acute Effects of Glucose and Fructose Administration on the Neural Correlates of Cognitive Functioning in Healthy Subjects: A Pilot Study. AB - The present randomized double-blinded cross-over study aims to extensively study the neural correlates underpinning cognitive functions in healthy subjects after acute glucose and fructose administration, using an integrative multimodal neuroimaging approach. Five minutes after glucose, fructose, or placebo administration through a nasogastric tube, 12 participants underwent 3 complementary neuroimaging techniques: 2 task-based functional magnetic resonance imaging (fMRI) sequences to assess working memory (N-back) and response inhibition (Go/No-Go) and one resting state fMRI sequence to address the cognition-related fronto-parietal network (FPN) and salience network (SN). During working memory processing, glucose intake decreased activation in the anterior cingulate cortex (ACC) relative to placebo, while fructose decreased activation in the ACC and sensory cortex relative to placebo and glucose. During response inhibition, glucose and fructose decreased activation in the ACC, insula and visual cortex relative to placebo. Resting state fMRI indicated increased global connectivity strength of the FPN and the SN during glucose and fructose intake. The results demonstrate that glucose and fructose lead to partially different partially overlapping changes in regional brain activities that underpin cognitive performance in different tasks. PMID- 29593584 TI - Utilization of Mental Health Care, Treatment Patterns, and Course of Psychosocial Functioning in Northern German Coronary Artery Disease Patients with Depressive and/or Anxiety Disorders. AB - Background: Comorbid mental disorders in patients with coronary artery disease (CAD) are common and associated with adverse somatic outcomes. However, data on utilization rates of mental health care and treatment efficiency are scarce and inconsistent, which we tried to remedy with the present preliminary study on Northern German CAD patients. Method: A total of 514 German CAD patients, as diagnosed by cardiac catheterization, were assessed using the Mini International Neuropsychiatric Interview and the Global Assessment of Functioning (GAF) scale. Results: Global utilization of mental health care since onset of CAD was 21.0%. Depressive disorders, younger age, and lower GAF at onset of CAD were associated with higher utilization rates, while anxiety disorders and gender were not. Lower GAF at onset of CAD, female gender, and psychotherapy was positively associated with higher gains in GAF, while younger age and anxiety disorders were negatively associated. Conclusion: The majority of CAD patients with comorbid depression reported to have received mental health treatment and seemed to have benefited from it. However, we found preliminary evidence of insufficiencies in the diagnosis and treatment of anxiety disorders in CAD patients. Further studies, preferably prospective and with representative samples, are needed to corroborate or falsify these findings and explore possible further mediators of health-care utilization by CAD patients such as race, ethnicity, and socioeconomic status. PMID- 29593585 TI - Functional Magnetic Resonance Spectroscopy: The "New" MRS for Cognitive Neuroscience and Psychiatry Research. AB - Proton magnetic resonance spectroscopy (1H MRS) is a well-established technique for quantifying the brain regional biochemistry in vivo. In most studies, however, the 1H MRS is acquired during rest with little to no constraint on behavior. Measured metabolite levels, therefore, reflect steady-state concentrations whose associations with behavior and cognition are unclear. With the recent advances in MR technology-higher-field MR systems, robust acquisition techniques and sophisticated quantification methods-1H MRS is now experiencing a resurgence. It is sensitive to task-related and pathology-relevant regional dynamic changes in neurotransmitters, including the most ubiquitous among them, glutamate. Moreover, high temporal resolution approaches allow tracking glutamate modulations at a time scale of under a minute during perceptual, motor, and cognitive tasks. The observed task-related changes in brain glutamate are consistent with new metabolic steady states reflecting the neural output driven by shifts in the local excitatory and inhibitory balance on local circuits. Unlike blood oxygen level differences-base functional MRI, this form of in vivo MRS, also known as functional MRS (1H fMRS), yields a more direct measure of behaviorally relevant neural activity and is considerably less sensitive to vascular changes. 1H fMRS enables noninvasive investigations of task-related glutamate changes that are relevant to normal and impaired cognitive performance, and psychiatric disorders. By targeting brain glutamate, this approach taps into putative neural correlates of synaptic plasticity. This review provides a concise survey of recent technological advancements that lay the foundation for the successful use of 1H fMRS in cognitive neuroscience and neuropsychiatry, including a review of seminal 1H fMRS studies, and the discussion of biological significance of task-related changes in glutamate modulation. We conclude with a discussion of the promises, limitations, and outstanding challenges of this new tool in the armamentarium of cognitive neuroscience and psychiatry research. PMID- 29593586 TI - The Association Between Suicidal Behavior, Attentional Control, and Frontal Asymmetry. AB - It can be difficult to identify those at risk of suicide because suicidal thoughts are often internalized and not shared with others. Yet to prevent suicide attempts it is crucial to identify suicidal thoughts and actions at an early stage. Past studies have suggested that deficits in attentional control are associated with suicide, with the argument that individuals are unable to inhibit negative thoughts and direct resources away from negative information. The current study aimed to investigate the association of suicidal behavior with neurological and behavioral markers, measuring attentional bias and inhibition in two Stroop tasks. Fifty-four participants responded to the color of color words in a standard Stroop task and the color of positive, negative, and neutral words in an emotional Stroop task. Electroencephalographic (EEG) activity was recorded from frontal areas during each task and at resting. Participants were separated into a low-risk and high-risk group according to their self-reported suicidal behavior. Participants in the high-risk group showed slower response times in the color Stroop and reduced accuracy to incongruent trials, but faster response times in the emotional Stroop task. Response times to the word "suicide" were significantly slower for the high-risk group. This indicates an attentional bias toward specific negative stimuli and difficulties inhibiting information for those with high levels of suicidal behavior. In the emotional Stroop task the high-risk group showed reduced activity in leftward frontal areas, suggesting limitations in the ability to regulate emotional processing via the left frontal regions. The findings support the argument that deficits in attentional control are related to suicidal behavior. The research also suggests that under certain conditions frontal asymmetry may be associated with suicidal behavior. PMID- 29593587 TI - Circulating MicroRNA Expression Levels Associated With Internet Gaming Disorder. AB - Background: Addictive use of the Internet and online games is a potential psychiatric disorder termed Internet gaming disorder (IGD). Altered microRNA (miRNA) expression profiles have been reported in blood and brain tissue of patients with certain psychiatric disorders and suggested as biomarkers. However, there have been no reports on blood miRNA profiles in IGD. Methods: To discover IGD-associated miRNAs, we analyzed the miRNA expression profiles of 51 samples (25 IGD and 26 controls) using the TaqMan Low Density miRNA Array. For validation, we performed quantitative reverse transcription PCR with 36 independent samples (20 IGD and 16 controls). Results: Through discovery and independent validation, we identified three miRNAs (hsa-miR-200c-3p, hsa-miR-26b 5p, hsa-miR-652-3p) that were significantly downregulated in the IGD group. Individuals with all three miRNA alterations had a much higher risk of IGD than those with no alteration [odds ratio (OR) 22, 95% CI 2.29-211.11], and the ORs increased dose dependently with number of altered miRNAs. The predicted target genes of the three miRNAs were associated with neural pathways. We explored the protein expression of the three downstream target genes by western blot and confirmed that expression of GABRB2 and DPYSL2 was significantly higher in the IGD group. Conclusion: We observed that expressions of hsa-miR-200c-3p, hsa-miR 26b-5p, and hsa-miR-652-3p were downregulated in the IGD patients. Our results will be helpful to understand the pathophysiology of IGD. PMID- 29593588 TI - Carbonyl Stress and Microinflammation-Related Molecules as Potential Biomarkers in Schizophrenia. AB - This literature review primarily aims to summarize our research, comprising both cross-sectional and longitudinal studies, and discuss the possibility of using microinflammation-related biomarkers as peripheral biomarkers in the diagnosis and monitoring of patients with schizophrenia. To date, several studies have been conducted on peripheral biomarkers to recognize the potential markers for the diagnosis of schizophrenia and to determine the state and effects of therapy in patients with schizophrenia. Research has established a correlation between carbonyl stress, an environmental factor, and the pathophysiology of neuropsychiatric diseases, including schizophrenia. In addition, studies on biomarkers related to these stresses have achieved results that are either replicable or exhibit consistent increases or decreases in patients with schizophrenia. For instance, pentosidine, an advanced glycation end product (AGE), is considerably elevated in patients with schizophrenia; however, low levels of vitamin B6 [a detoxifier of reactive carbonyl compounds (RCOs)] have also been reported in some patients with schizophrenia. Another study on peripheral markers of carbonyl stress in patients with schizophrenia revealed a correlation of higher levels of glyceraldehyde-derived AGEs with higher neurotoxicity and lower levels of soluble receptors capable of diminishing the effects of AGEs. Furthermore, studies on evoked microinflammation-related biomarkers (e.g., soluble tumor necrosis factor receptor 1) have reported relatively consistent results, suggesting the involvement of microinflammation in the pathophysiology of schizophrenia. We believe that our cross-sectional and longitudinal studies as well as various previous inflammation marker studies that could be interpreted from several perspectives, such as mild localized encephalitis and microvascular disturbance, highlighted the importance of early intervention as prevention and distinguished the possible exclusion of inflammations in schizophrenia. PMID- 29593589 TI - Comorbid Diagnosis of Psychotic Disorders in Borderline Personality Disorder: Prevalence and Influence on Outcome. AB - Background: A diagnosis of psychotic disorder is traditionally considered incompatible with borderline personality disorder (BPD), even though patients sometimes fulfill the diagnostic criteria for both disorders. How often this happens is barely known, as is the influence of comorbid psychotic disorders on the outcome of BPD. Since studies on isolated auditory verbal hallucinations in patients with BPD indicate that these perceptual symptoms have severe consequences and are associated with suicidal behavior and hospitalization, patients with comorbid psychotic disorders are unlikely to fare better. Objective: To examine the point prevalence of psychotic disorders in patients with BPD, their association with the outcome of BPD, and their predictive value for outcome. Methods: In a cross-sectional design, 84 female outpatients diagnosed with BPD were interviewed with the aid of the MINI-International Neuropsychiatric Interview to establish the point prevalence of comorbid psychotic and other comorbid disorders. After termination of their treatment at a specialized outpatient clinic, the type of referral was considered to be a "good" outcome when they were referred to their general practitioner or to basic psychiatric care for noncomplex patients, and a "poor" outcome when referred to a specialized psychiatric department or to a psychiatric district team for patients with severe psychiatric disorders. Results: Psychotic disorders were present in 38% of the patients with BPD. With a prevalence of 20%, psychotic disorder not otherwise specified (NOS) was the most common subtype; the least common types were schizophrenia (2%), substance-induced psychotic disorder (2%), and brief psychotic disorder (1%). Among six types of comorbid disorders, only psychotic disorders were associated with a poor outcome; they were also predictors for a poor outcome, along with comorbid mood disorders, eating disorders, and somatoform disorders, as well as the severity of BPD, and, counterintuitively, more years of education. Conclusion: Psychotic disorders, notably of the psychotic disorder NOS subtype, are common among patients with BPD, and their presence is associated with a poor outcome. This implies that adequate diagnosis and treatment of both disorders is warranted in this subgroup with a dual diagnosis. PMID- 29593590 TI - Plasticity, Variability and Age in Second Language Acquisition and Bilingualism. AB - Much of what is known about the outcome of second language acquisition and bilingualism can be summarized in terms of inter-individual variability, plasticity and age. The present review looks at variability and plasticity with respect to their underlying sources, and at age as a modulating factor in variability and plasticity. In this context we consider critical period effects vs. bilingualism effects, early and late bilingualism, nativelike and non nativelike L2 attainment, cognitive aging, individual differences in learning, and linguistic dominance in bilingualism. Non-uniformity is an inherent characteristic of both early and late bilingualism. This review shows how plasticity and age connect with biological and experiential sources of variability, and underscores the value of research that reveals and explains variability. In these ways the review suggests how plasticity, variability and age conspire to frame fundamental research issues in L2 acquisition and bilingualism, and provides points of reference for discussion of the present Frontiers in Psychology Research Topic. PMID- 29593591 TI - Assessing Individual Change Without Knowing the Test Properties: Item Bootstrapping. AB - Assessing significant change (or reliable change) in a person often involve comparing the responses of that person in two administrations of a test or scale. Several procedures have been proposed to determine if a difference between two observed scores is statistically significant or rather is within the range of mere random fluctuations due to measurement error. Application of those procedures involve some knowledge of the test properties. But sometimes those procedures cannot be employed because the properties are unknown or are not trustworthy. In this paper we propose the bootstrap of items procedure to create confidence intervals of the individual's scores without using any known psychometric properties of the test. Six databases containing the responses of several groups to one or more subscales have been analyzed using two methods: bootstrap of items and a classical procedure based on confidence intervals to estimate the true score. The rates of significant change obtained were very similar, suggesting that item bootstrapping is a promising solution when other methods cannot be applied. PMID- 29593593 TI - Using iMCFA to Perform the CFA, Multilevel CFA, and Maximum Model for Analyzing Complex Survey Data. AB - To construct CFA, MCFA, and maximum MCFA with LISREL v.8 and below, we provide iMCFA (integrated Multilevel Confirmatory Analysis) to examine the potential multilevel factorial structure in the complex survey data. Modeling multilevel structure for complex survey data is complicated because building a multilevel model is not an infallible statistical strategy unless the hypothesized model is close to the real data structure. Methodologists have suggested using different modeling techniques to investigate potential multilevel structure of survey data. Using iMCFA, researchers can visually set the between- and within-level factorial structure to fit MCFA, CFA and/or MAX MCFA models for complex survey data. iMCFA can then yield between- and within-level variance-covariance matrices, calculate intraclass correlations, perform the analyses and generate the outputs for respective models. The summary of the analytical outputs from LISREL is gathered and tabulated for further model comparison and interpretation. iMCFA also provides LISREL syntax of different models for researchers' future use. An empirical and a simulated multilevel dataset with complex and simple structures in the within or between level was used to illustrate the usability and the effectiveness of the iMCFA procedure on analyzing complex survey data. The analytic results of iMCFA using Muthen's limited information estimator were compared with those of Mplus using Full Information Maximum Likelihood regarding the effectiveness of different estimation methods. PMID- 29593592 TI - Acute Bouts of Exercising Improved Mood, Rumination and Social Interaction in Inpatients With Mental Disorders. AB - Background: Studies at the macro level (such as longer-term interventions) showed that physical activity impacts positively on cognitive-emotional processes of patients with mental disorders. However, research focusing on the immediate impact of acute bouts of exercise (micro level) are missing. The aim of the present study was therefore to investigate whether and to what extent single bouts of moderately intense exercise can influence dimensions of psychological functioning in inpatients with mental disorders. Method: 129 inpatients (mean age: 38.16 years; 50.4% females) took part and completed a questionnaire both immediately before and immediately after exercising. Thirty inpatients completed the questionnaires a second time in the same week. The questionnaire covered socio-demographic and illness-related information. Further, the questionnaire asked about current psychological states such as mood, rumination, social interactions, and attention, tiredness, and physical strengths as a proxy of physiological states. Results: Psychological states improved from pre- to post session. Improvements were observed for mood, social interactions, attention, and physical strengths. Likewise, rumination and tiredness decreased. Mood, rumination, and tiredness further improved, when patients completed the questionnaires the second time in the same week. Conclusion: At micro level, single bouts of exercise impacted positively on cognitive-emotional processes such as mood, rumination, attention and social interactions, and physiological states of tiredness and physical strengths among inpatients with mental disorders. In addition, further improvements were observed, if patients participated in physical activities a second time.

AB - Two lexical priming experiments were conducted to examine effects of grammatical structure of Chinese two-constituent compounds on their recognition. The target compound words conformed to two types of grammatical structure: subordinate and coordinative compounds. Subordinate compounds follow a structure where the first constituent modifies the second constituent (e.g., , meaning snowball); here the meaning of the second constituent (head) is modified by the first constituent (modifier). On the other hand, in coordinative compounds both constituents contribute equally to the word meaning (e.g., , wind and rain, meaning storm where the two constituent equally contribute to the word meaning). In Experiment 1 that was a replication attempt of Liu and McBride-Chang (2010), possible priming effects of word structure and semantic relatedness were examined. In lexical decision latencies only a semantic priming effect was observed. In Experiment 2, compound word structure and individual constituents were primed by the prime and target sharing either the first or second constituent. A structure priming effect was obtained in lexical decision times for subordinate compounds when the prime and target compound shared the same constituent. This suggests that a compound word constituent (either the modifier or the head) has to be simultaneously active with the structure information in order for the structure information to exert an effect on compound word recognition in Chinese. For the coordinative compounds the structure priming effect was non-significant. When the meaning of the whole word was primed (Experiment 1), no structure effect was observable. The pattern of results suggests that effects of structure priming are constituent-specific and no general structure priming was observable.

A Protocol for a Quasi Experimental, Cross-Sectional Design to Investigate Taste Aversion or Increased Hedonic Valence of Food in Eating Disorders. AB - Background: Despite on-going efforts to better understand dysregulated eating, the olfactory-gustatory deficits and food preferences in eating disorders (ED), and the mechanisms underlying the perception of and responses to food properties in anorexia nervosa (AN) and bulimia nervosa (BN) remain largely unknown; both during the course of the illness and compared to healthy populations. It is, therefore, necessary to systematically investigate the gustatory perception and hedonics of taste in patients with AN and BN. To this end, we will examine whether aversions to the taste of high-calorie food is related to the suppression of energy intake in restricting-type AN, and whether an increased hedonic valence of sweet, caloric-dense foods may be part of the mechanisms triggering binge eating episodes in BN. In addition, the role of cognitions influencing these mechanisms will be examined. Method: In study 1, four mixtures of sweet-fat stimuli will be presented in a sensory two-alternative forced-choice test involving signal detection analysis. In study 2, a full-scale taste reactivity test will be carried out, including psychophysiological and behavioral measures to assess subtle and covert hedonic changes. We will compare the responses of currently-ill AN and BN patients to those who have recovered from AN and BN, and also to those of healthy normal-weight and underweight individuals without any eating disorder pathology. Discussion: If taste response profiles are differentially linked to ED types, then future studies should investigate whether taste responsiveness represents a useful diagnostic measure in the prevention, assessment and treatment of EDs. The expected results on cognitive mechanisms in the top-down processes of food hedonics will complement current models and contribute to the refinement of interventions to change cognitive aspects of taste aversions, to establish functional food preferences and to better manage food cravings associated with binge-eating episodes. No trial registration was required for this protocol, which was approved by the Swiss ethics committee (CER VD, n degrees 2016-02150) and the Ethics Review Panel of the University of Luxembourg. PMID- 29593597 TI - Comprehension of Generalized Conversational Implicatures by Children With and Without Autism Spectrum Disorder. AB - This study evaluates the comprehension of generalized conversational implicatures (GCI) in children with and without autism spectrum disorder (ASD), using a GCI test constructed based on the Levinson model, which distinguishes between three types of implicatures: type Q (or scalar: "what is not referred to does not occur"); type I ("by default, it is not necessary to say what can be assumed"); and type M ("if someone is expressing something in a not very simple or marked way, it is because s/he is describing a situation that is not very typical, frequent, or prototypical"). In addition to the ASD group (n = 22), two comparison groups were utilized: a group matched on chronological age with the ASD group, but with a higher linguistic age (TCD group, n = 22), and a group matched on linguistic age with the ASD group, but with a lower chronological age (TLD group, n = 22). In all cases, linguistic age was assessed with the Peabody test. The performance of the three groups on the GCI test was compared (overall and on each type of implicature), and performance on the three types of implicature was compared within each group. The ASD group obtained worse performance than the other two groups, both overall and for each implicature type, without also obtaining differences in performance on the three implicature types. The TCD group obtained better performance than the TLD group on overall performance, but not on each implicature type, and both groups obtained lower performance on the type M heuristics than on the type I. Based on these results, the children with ASD in our study presented limitations in the comprehension of the three types of GCI, but it was not possible to obtain evidence for an inferential continuum of the three types of GCI. However, in the two typical development groups, this evidence was obtained, leading us to propose an inferential continuum model based on the different levels of dependence on the context of each of the three types of implicatures, with type M implicatures being more contextually dependent. PMID- 29593596 TI - Neural Dynamics of Autistic Repetitive Behaviors and Fragile X Syndrome: Basal Ganglia Movement Gating and mGluR-Modulated Adaptively Timed Learning. AB - This article develops the iSTART neural model that proposes how specific imbalances in cognitive, emotional, timing, and motor processes that involve brain regions like prefrontal cortex, temporal cortex, amygdala, hypothalamus, hippocampus, and cerebellum may interact together to cause behavioral symptoms of autism. These imbalances include underaroused emotional depression in the amygdala/hypothalamus, learning of hyperspecific recognition categories that help to cause narrowly focused attention in temporal and prefrontal cortices, and breakdowns of adaptively timed motivated attention and motor circuits in the hippocampus and cerebellum. The article expands the model's explanatory range by, first, explaining recent data about Fragile X syndrome (FXS), mGluR, and trace conditioning; and, second, by explaining distinct causes of stereotyped behaviors in individuals with autism. Some of these stereotyped behaviors, such as an insistence on sameness and circumscribed interests, may result from imbalances in the cognitive and emotional circuits that iSTART models. These behaviors may be ameliorated by operant conditioning methods. Other stereotyped behaviors, such as repetitive motor behaviors, may result from imbalances in how the direct and indirect pathways of the basal ganglia open or close movement gates, respectively. These repetitive behaviors may be ameliorated by drugs that augment D2 dopamine receptor responses or reduce D1 dopamine receptor responses. The article also notes the ubiquitous role of gating by basal ganglia loops in regulating all the functions that iSTART models. PMID- 29593598 TI - How to Detect Insight Moments in Problem Solving Experiments. AB - Arguably, it is not possible to study insight moments during problem solving without being able to accurately detect when they occur (Bowden and Jung-Beeman, 2007). Despite over a century of research on the insight moment, there is surprisingly little consensus on the best way to measure them in real-time experiments. There have also been no attempts to evaluate whether the different ways of measuring insight converge. Indeed, if it turns out that the popular measures of insight diverge, then this may indicate that researchers who have used one method may have been measuring a different phenomenon to those who have used another method. We compare the strengths and weaknesses of the two most commonly cited ways of measuring insight: The feelings-of-warmth measure adapted from Metcalfe and Wiebe (1987), and the self-report measure adapted from Bowden and Jung-Beeman (2007). We find little empirical agreement between the two measures, and conclude that the self-report measure of Aha! is superior both methodologically and theoretically, and provides a better representation of what is commonly regarded as insight. We go on to describe and recommend a novel visceral measure of insight using a dynamometer as described in Creswell et al. (2016). PMID- 29593599 TI - Recounting a Common Experience: On the Effectiveness of Instructing Eyewitness Pairs. AB - Pairs of eyewitnesses with a content-focused interaction style remember significantly more about witnessed incidents. We examined whether content-focused retrieval strategies can be taught. Seventy-five pairs of witnesses were interviewed thrice about an event. The first and third interview were conducted individually for all witnesses. The second interview was individual, collaborative without instruction, or collaborative with instruction. Pairs in the latter condition were instructed to actively listen to and elaborate upon each other's contributions. The strategy instruction had no effect on retrieval strategies used, nor on the amount or accuracy of reported information. However, pairs who spontaneously adopted a content-focused interaction style during the collaborative interview remembered significantly more. Thus, our findings show that effective retrieval strategies cannot be taught, at least not with the current instructions. During the second interview, we observed collaborative inhibition and error pruning. When considering the total amount of information reported across the first two interviews, however, collaboration had no inhibitory effect on correct recall, yet the error pruning benefits remained. These findings suggest that investigative interviewers should interview witnesses separately first, and then interview pairs of witnesses collaboratively. PMID- 29593601 TI - Designing Smart Objects to Support Affording Situations: Exploiting Affordance Through an Understanding of Forms of Engagement. AB - In this paper I consider how the concept of "affordance" has been adapted from the original writings of Gibson and applied to interaction design. I argue that a clear understanding of affordance shifts the goal of interaction design from one of solely focusing on either the physical object or the capabilities of the person, toward an understanding of interactivity. To do this, I develop the concept of Forms of Engagement, originally proposed to account for tool use. Finally, I extend this concept to interacting with modified tangible user interfaces, or "animate objects." These animate objects not only sense how they are being used, but also communicate with each other to develop a shared intent, and provide prompts and cues to encourage specific actions. In this way, the human-object-environment system creates affording situations in pursuit of shared intentions and goals. In order to determine when to provide prompts and cues, the objects need to have a model of how they ought to be used and what intention they are being used to achieve. Consequently, affordances become not only the means by which actions are encouraged but also the manner in which intentions are identified and agreed. PMID- 29593600 TI - Action Prediction Allows Hypothesis Testing via Internal Forward Models at 6 Months of Age. AB - We propose that action prediction provides a cornerstone in a learning process known as internal forward models. According to this suggestion infants' predictions (looking to the mouth of someone moving a spoon upward) will moments later be validated or proven false (spoon was in fact directed toward a bowl), information that is directly perceived as the distance between the predicted and actual goal. Using an individual difference approach we demonstrate that action prediction correlates with the tendency to react with surprise when social interactions are not acted out as expected (action evaluation). This association is demonstrated across tasks and in a large sample (n = 118) at 6 months of age. These results provide the first indication that infants might rely on internal forward models to structure their social world. Additional analysis, consistent with prior work and assumptions from embodied cognition, demonstrates that the latency of infants' action predictions correlate with the infant's own manual proficiency. PMID- 29593602 TI - Bouba/Kiki in Touch: Associations Between Tactile Perceptual Qualities and Japanese Phonemes. AB - Several studies have shown cross-modal associations between sounds and vision or gustation by asking participants to match pre-defined sound-symbolic words (SSWs), such as "bouba" or "kiki," with visual or gustatory materials. Here, we conducted an explorative study on cross-modal associations of tactile sensations using spontaneous production of Japanese SSWs and semantic ratings. The Japanese language was selected, because it has a large number of SSWs that can represent a wide range of tactile perceptual spaces with fine resolution, and it shows strong associations between sound and touch. In the experiment, we used 120 everyday materials to cover basic material categories that could be associated with fundamental dimensions of tactile perception. Upon contact with these materials, participants expressed their tactile sensations by using Japanese SSWs, and at the same time, evaluated the tactile sensations by semantic differential scales using adjective pairs. Thanks to the variety of testing materials, we were able to demonstrate the existence of systematic associations between sounds and tactile fundamental perceptual dimensions in a more detailed and comprehensive way than ever done so before. In particular, we found that for vowels, positive tactile ratings were associated with the back vowel (/u/), while negative ratings were associated with the front vowels (/i/ and /e/). The central vowels (/o/ and /a/) were mainly associated with rough, hard, and dry feelings. Consonants were categorized based on vocal features and articulation. The category of the voiced consonants (e.g., /dz/ and /g/) corresponded to feelings of roughness, while that of voiceless consonants (e.g., /ts/, and /s/) corresponded to feelings of smoothness. The categories of the bilabial plosive (/p/ and /b/) and voiced alveolar nasal (/n/) consonants were mainly related to soft, sticky and wet feelings, while that of voiceless alveolar affricate (/ts/) and voiceless velar plosive (/k/) consonants were related to hard, slippery and dry feelings. PMID- 29593603 TI - Academic Well-Being, Mathematics Performance, and Educational Aspirations in Lower Secondary Education: Changes Within a School Year. AB - It has been suggested that both performance and academic well-being play a role in adolescent students' educational attainment and school dropout. In this study, we therefore examined, first, what kinds of academic well-being (i.e., school burnout, schoolwork engagement, and mathematics self-concept) and mathematics performance profiles can be identified among lower secondary school students (Ngrade 7 = 583, Ngrade 9 = 497); second, how stable these profiles are across one school year during the seventh and ninth grades; and, third, how students with different academic well-being and mathematics performance profiles differ with respect to their educational aspirations. By means of latent profile analyses, three groups of students in seventh grade: thriving (34%), average (51%), and negative academic well-being (15%) and four groups of students in ninth grade: thriving (25%), average (50%), negative academic well-being (18%), and low-performing (7%) with distinct well-being and mathematics performance profiles were identified. Configural frequency analyses revealed that the profiles were relatively stable across one school year; 60% of the students displayed identical profiles over time. The thriving students reported the highest educational aspirations compared to the other groups. In addition, the low-performing students in the ninth grade had the lowest educational aspirations just before the transition to upper secondary school. Practical implications as well as directions for future research are discussed. PMID- 29593605 TI - EEG Correlates of the Flow State: A Combination of Increased Frontal Theta and Moderate Frontocentral Alpha Rhythm in the Mental Arithmetic Task. AB - Flow experience is a subjective state experienced during holistic involvement in a certain activity, which has been reported to function as a factor promoting motivation, skill development, and better performance in the activity. To verify the positive effects of flow and develop a method to utilize it, the establishment of a reliable measurement of the flow state is essential. The present study utilized an electroencephalogram (EEG) during an experimentally evoked flow state and examined the possibility of objective measurement of immediate flow. A total of 16 participants (10 males, 6 females) participated in the experiment that employed a mental arithmetic task developed in a previous study. Post-trial self-report of the flow state and EEG during task execution were measured and compared among three conditions (Boredom, Flow, and Overload) that had different levels of task difficulty. Furthermore, the correlations between subjective flow items and EEG activity were examined. As expected, the ratings on the subjective evaluation items representing the flow state were the highest in the Flow condition. Regarding the EEG data, theta activities in the frontal areas were higher in the Flow and the Overload conditions than in the Boredom condition, and alpha activity in the frontal areas and the right central area gradually increased depending on the task difficulty. These EEG activities correlated with self-reported flow experience, especially items related to the concentration on the task and task difficulty. From the results, the flow state was characterized by increased theta activities in the frontal areas and moderate alpha activities in the frontal and central areas. The former may be related to a high level of cognitive control and immersion in task, and the latter suggests that the load on the working memory was not excessive. The findings of this study suggest the possibility of distinguishing the flow state from other states using multiple EEG activities and indicate the need for other physiological indicators corresponding to the other aspects of flow experience. PMID- 29593604 TI - Moderators Influencing the Effectiveness of a Behavioral Teacher Program. AB - Objective: This study assessed which moderators influenced the effectiveness of a low-intensive behavioral teacher program for children with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). Methods: Primary school children (N = 114) with ADHD symptoms in the classroom were randomly assigned to the intervention program (n = 58; 91% male) or control group (n = 56; 77% male). Multilevel regression analyses assessed differential treatment gains of the intervention program in terms of ADHD symptoms and social skills. Moderators included demographic characteristics (gender, age, parental educational level), severity and comorbidity of problem behavior (ADHD symptoms, conduct and internalizing problems), social functioning, and classroom variables (teaching experience, class size). Results: Results revealed larger program effects for older children and children from highly educated families and smaller beneficial effects for children with comorbid conduct or anxiety problems. Conclusion: The intervention program seems more beneficial for highly educated families and children without comorbid problem behavior, but more intensive treatments appear necessary for children facing additional challenges.

AB - The purpose of this study was to examine the role of exploration strategies students used in the first phase of problem solving. The sample for the study was drawn from 3rd- to 12th-grade students (aged 9-18) in Hungarian schools (n = 4,371). Problems designed in the MicroDYN approach with different levels of complexity were administered to the students via the eDia online platform. Logfile analyses were performed to ascertain the impact of strategy use on the efficacy of problem solving. Students' exploration behavior was coded and clustered through Latent Class Analyses. Several theoretically effective strategies were identified, including the vary-one-thing-at-a-time (VOTAT) strategy and its sub-strategies. The results of the analyses indicate that the use of a theoretically effective strategy, which extract all information required to solve the problem, did not always lead to high performance. Conscious VOTAT strategy users proved to be the best problem solvers followed by non-conscious VOTAT strategy users and non-VOTAT strategy users. In the primary school sub sample, six qualitatively different strategy class profiles were distinguished. The results shed new light on and provide a new interpretation of previous analyses of the processes involved in complex problem solving. They also highlight the importance of explicit enhancement of problem-solving skills and problem-solving strategies as a tool for knowledge acquisition in new contexts during and beyond school lessons. PMID- 29593607 TI - Observation of Point-Light-Walker Locomotion Induces Motor Resonance When Explicitly Represented; An EEG Source Analysis Study. AB - Understanding human motion, to infer the goal of others' actions, is thought to involve the observer's motor repertoire. One prominent class of actions, the human locomotion, has been object of several studies, all focused on manipulating the shape of degraded human figures like point-light walker (PLW) stimuli, represented as walking on the spot. Nevertheless, since the main goal of the locomotor function is to displace the whole body from one position to the other, these stimuli might not fully represent a goal-directed action and thus might not be able to induce the same motor resonance mechanism expected when observing a natural locomotion. To explore this hypothesis, we recorded the event-related potentials (ERP) of canonical/scrambled and translating/centered PLWs decoding. We individuated a novel ERP component (N2c) over central electrodes, around 435 ms after stimulus onset, for translating compared to centered PLW, only when the canonical shape was preserved. Consistently with our hypothesis, sources analysis associated this component to the activation of trunk and lower legs primary sensory-motor and supplementary motor areas. These results confirm the role of own motor repertoire in processing human action and suggest that ERP can detect the associated motor resonance only when the human figure is explicitly involved in performing a meaningful action. PMID- 29593608 TI - No Evidence for Phase-Specific Effects of 40 Hz HD-tACS on Multiple Object Tracking. AB - Phase synchronization drives connectivity between neural oscillators, providing a flexible mechanism through which information can be effectively and selectively routed between task-relevant cortical areas. The ability to keep track of objects moving between the left and right visual hemifields, for example, requires the integration of information between the two cerebral hemispheres. Both animal and human studies have suggested that coherent (or phase-locked) gamma oscillations (30-80 Hz) might underlie this ability. While most human evidence has been strictly correlational, high-density transcranial alternating current stimulation (HD-tACS) has been used to manipulate ongoing interhemispheric gamma phase relationships. Previous research showed that 40 Hz tACS delivered bilaterally over human motion complex could bias the perception of a bistable ambiguous motion stimulus (Helfrich et al., 2014). Specifically, this work showed that in phase (0 degrees offset) stimulation boosted endogenous interhemispheric gamma coherence and biased perception toward the horizontal (whereby visual tokens moved between visual hemifields-requiring interhemispheric integration). By contrast, anti-phase (180 degrees offset) stimulation decreased interhemispheric gamma coherence and biased perception toward the vertical (whereby tokens moved within separate visual hemifields). Here we devised a multiple object tracking arena comprised of four quadrants whereby discrete objects moved either entirely within the left and right visual hemifields, or could cross freely between visual hemifields, thus requiring interhemispheric integration. Using the same HD-tACS montages as Helfrich et al. (2014), we found no phase-specific effect of 40 Hz stimulation on overall tracking performance. While tracking performance was generally lower during between-hemifield trials (presumably reflecting a cost of integration), this difference was unchanged by in- vs. anti-phase stimulation. Our null results could be due to a failure to reliably modulate coherence in our study, or that our task does not rely as heavily on this network of coherent gamma oscillations as other visual integration paradigms. PMID- 29593609 TI - Early-Life Stressors, Personality Development, and Fast Life Strategies: An Evolutionary Perspective on Malevolent Personality Features. AB - Life history theory posits that behavioral adaptation to various environmental (ecological and/or social) conditions encountered during childhood is regulated by a wide variety of different traits resulting in various behavioral strategies. Unpredictable and harsh conditions tend to produce fast life history strategies, characterized by early maturation, a higher number of sexual partners to whom one is less attached, and less parenting of offspring. Unpredictability and harshness not only affects dispositional social and emotional functioning, but may also promote the development of personality traits linked to higher rates of instability in social relationships or more self-interested behavior. Similarly, detrimental childhood experiences, such as poor parental care or high parent child conflict, affect personality development and may create a more distrustful, malicious interpersonal style. The aim of this brief review is to survey and summarize findings on the impact of negative early-life experiences on the development of personality and fast life history strategies. By demonstrating that there are parallels in adaptations to adversity in these two domains, we hope to lend weight to current and future attempts to provide a comprehensive insight of personality traits and functions at the ultimate and proximate levels. PMID- 29593610 TI - Exploring an Age Difference in Preschool Children's Competitiveness Following a Competition. AB - Literature suggests that resource acquisition compels competition in young children. However, little is still known about the development of preschool children's competitiveness. In this preliminary study, 166 children (aged 2-4 and 5-6 years) engaged in a dyadic competition which resulted in a winning and a losing group (in a control/non-competition group, participants engaged in a similar task which did not lead to winning/losing outcome), and then experimenters tracked their decisions to compete again with a rival (i.e., an individual they interacted in the previous competition task) and a non-rival competitor (i.e., an anonymous classmate they did not interact in the previous competition task) for a reward, respectively. As expected, results showed an age related decreasing trend in the percentage of choices to compete with a competitor. However, this age difference was only significant in the control group when participants played with the partner with whom they interacted in the previous game and in the losing group when participants competed with a non-rival competitor. This study contributes to our knowledge of how competitiveness develop in preschool childhood, and calls for further research on the roles of motivation and cognitive control in children's competitiveness. PMID- 29593611 TI - Evaluation and Adaption of the Trier Inventory for Chronic Stress (TICS) for Assessment in Competitive Sports. AB - The demands of a career in competitive sports can lead to chronic stress perception among athletes if there is a non-conformity of requirements and available coping resources. The Trier Inventory for Chronic Stress (TICS) (Schulz et al., 2004) is said to be thoroughly validated. Nevertheless, it has not yet been subjected to a confirmatory factor analysis. The present study aims (1) to evaluate the factorial validity of the TICS within the context of competitive sports and (2) to adapt a short version (TICS-36). The total sample consisted of 564 athletes (age in years: M = 19.1, SD = 3.70). The factor structure of the original TICS did not adequately fit the present data, whereas the short version presented a satisfactory fit. The results indicate that the TICS-36 is an economical instrument for gathering interpretable information about chronic stress. For assessment in competitive sports with TICS-36, we generated overall and gender-specific norm values. PMID- 29593612 TI - Efficiency in Rule- vs. Plan-Based Movements Is Modulated by Action-Mode. AB - The rule/plan motor cognition (RPMC) paradigm elicits visually indistinguishable motor outputs, resulting from either plan- or rule-based action-selection, using a combination of essentially interchangeable stimuli. Previous implementations of the RPMC paradigm have used pantomimed movements to compare plan- vs. rule-based action-selection. In the present work we attempt to determine the generalizability of previous RPMC findings to real object interaction by use of a grasp-to-rotate task. In the plan task, participants had to use prospective planning to achieve a comfortable post-handle rotation hand posture. The rule task used implementation intentions (if-then rules) leading to the same comfortable end-state. In Experiment A, we compare RPMC performance of 16 healthy participants in pantomime and real object conditions of the experiment, within subjects. Higher processing efficiency of rule- vs. plan-based action-selection was supported by diffusion model analysis. Results show a significant response time increase in the pantomime condition compared to the real object condition and a greater response-time advantage of rule-based vs. plan-based actions in the pantomime compared to the real object condition. In Experiment B, 24 healthy participants performed the real object RPMC task in a task switching vs. a blocked condition. Results indicate that plan-based action-selection leads to longer response-times and less efficient information processing than rule-based action-selection in line with previous RPMC findings derived from the pantomime action-mode. Particularly in the task switching mode, responses were faster in the rule compared to the plan task suggesting a modulating influence of cognitive load. Overall, results suggest an advantage of rule-based action-selection over plan-based action-selection; whereby differential mechanisms appear to be involved depending on the action-mode. We propose that cognitive load is a factor that modulates the advantageous effect of implementation intentions in motor cognition on different levels as illustrated by the varying speed advantages and the variation in diffusion parameters per action-mode or condition, respectively. PMID- 29593613 TI - Ubiquitous Working: Do Work Versus Non-work Environments Affect Decision-Making and Concentration? AB - New communication technologies and mobile devices have enabled knowledge workers to work independently of location and in more than one fixed environment (ubiquitous working). Previous research shows that physical environments can influence cognition and work performance. We manipulated environment (i.e., a virtual office as a typical work environment compared to a virtual garden as a non-work environment) and time pressure (i.e., inducing time pressure vs. no time pressure) in order to investigate whether the environment influences decision making and concentration. N = 109 students participated in this laboratory experiment. We posited (a) that a work environment would activate a work-related schema which in turn would enhance concentration performance and make decisions more risky compared to non-work environments and (b) that the environmental effect is more pronounced if time pressure is present compared to conditions where no time pressure is present. We found modest hypothesis-confirming main effects of environment on decision-making and concentration but no interaction effect with time pressure. As we used an innovative methodology that entails several limitations, future research is needed to give insights into the process and to investigate whether results hold true for all types of work settings, work demands, or work activities. PMID- 29593614 TI - Effects of Single Compared to Dual Task Practice on Learning a Dynamic Balance Task in Young Adults. AB - Background: In everyday life, people engage in situations involving the concurrent processing of motor (balance) and cognitive tasks (i.e., "dual task situations") that result in performance declines in at least one of the given tasks. The concurrent practice of both the motor and cognitive task may counteract these performance decrements. The purpose of this study was to examine the effects of single task (ST) compared to dual task (DT) practice on learning a dynamic balance task. Methods: Forty-eight young adults were randomly assigned to either a ST (i.e., motor or cognitive task training only) or a DT (i.e., motor cognitive training) practice condition. The motor task required participants to stand on a platform and keeping the platform as close to horizontal as possible. In the cognitive task, participants were asked to recite serial subtractions of three. For 2 days, participants of the ST groups practiced the motor or cognitive task only, while the participants of the DT group concurrently performed both. Root-mean-square error (RMSE) for the motor and total number of correct calculations for the cognitive task were computed. Results: During practice, all groups improved their respective balance and/or cognitive task performance. With regard to the assessment of learning on day 3, we found significantly smaller RMSE values for the ST motor (d = 1.31) and the DT motor-cognitive (d = 0.76) practice group compared to the ST cognitive practice group but not between the ST motor and the DT motor-cognitive practice group under DT test condition. Further, we detected significantly larger total numbers of correct calculations under DT test condition for the ST cognitive (d = 2.19) and the DT motor-cognitive (d = 1.55) practice group compared to the ST motor practice group but not between the ST cognitive and the DT motor-cognitive practice group. Conclusion: We conclude that ST practice resulted in an effective modulation of the trained domain (i.e., motor or cognitive) while only DT practice resulted in an effective modulation of both domains (i.e., motor and cognitive). Thus, particularly DT practice frees up central resources that were used for an effective modulation of motor and cognitive processing mechanisms. PMID- 29593615 TI - Who Cares for Those Who Take Care? Risks and Resources of Work in Care Homes. AB - Over the years - due to the aging population, the process of corporatisation and a demand for a higher quality of services - professionals who work in Care Homes have been exposed to an increasing risk of physical and emotional malaise because of the number of challenges they've been asked to manage. Given these factors, there is a growing interest in the study and understanding of professions in geriatric care settings. In the literature there is a prevalence of quantitative studies offering an overview in terms of indicators - at the individual or group or organizational level - concerning the potential development of situations of professional malaise. Conversely, there is a lack of qualitative studies exploring the risk and protection factors. For this reason, in this study we decided to use a qualitative approach to explore "more up close" this kind of organizational context and to keep together the different levels in systemic terms in order to identify - according to professionals' perceptions - resource factors (in order to leverage these aspects) and fatigue factors (to identify them and treat them). Three Italian Care Homes were involved and the interview's sample was composed of 45 professionals - 15 nurses, 30 total Patient Care Assistants (PCAs) and Auxiliary Care Assistants (ACAs), of these, 17 males and 28 females, with an average age of 43 years (SD = 0.78) - selected using a sampling of maximum variability. From the analysis of the materials there seem to be four profiles of the professionals involved. Implications to ensure a functional human resource management are discussed for the purpose of promote the well-being of the various professionals, and, as a result, an increasing quality of service. PMID- 29593616 TI - Factor Structure of the Chinese Version of the Parent Adult-Child Relationship Questionnaire. AB - The Parent Adult-Child Relationship Questionnaire (PACQ) included two identical versions of the 13-item scale, which were administered to each subject, one which referred to "relationship with mother" and the other to "relationship with father." The PACQ, originally in English, is a self-report measure of the filial relationship. The present study aimed to develop a Chinese version of the PACQ and use it to explore Chinese parent adult-child relationships. A total of 454 Chinese adult-children completed the Chinese version of the PACQ. The structure of the questionnaire was analyzed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We found that the Cronbach's alpha was 0.66 0.88 for fathers and 0.76-0.91 for mothers, which demonstrates high internal consistency reliabilities of the Chinese version of the PACQ. The Chinese version of the PACQ for father had similar constructs similar to with those of the original English version. However, a new factor for mothers, "attachment," was derived from the original English version. The results suggested that the Chinese version of PACQ is a valid and reliable measure of relationship quality between Chinese adult-children and their parents. PMID- 29593617 TI - The Role of Difficulty in Identifying and Describing Feelings in Non-Suicidal Self-Injury Behavior (NSSI): Associations With Perceived Attachment Quality, Stressful Life Events, and Suicidal Ideation. AB - Objective: Core alexithymic features, such as the difficulty in identifying and describing feelings, are associated with poor attachment styles and emotional trauma, which influence the capacity to regulate affect. Additionally, emotional regulation has been found to be the most commonly identified function associated with non-suicidal self-injury behavior (NSSI) in adolescents as they attempt to modulate strong emotions. However, few studies have examined the link between difficulty in identifying and describing feelings (core components of alexithymia), NSSI behaviors, quality of attachment, life stressors and suicidal ideation in healthy early adolescents. Consequently, this study aims to investigate these constructs and the relationship among them in a large non clinical sample of adolescents. Methods: Seven hundred and nine middle school students (50.4% males), aged 10-15 years (M = 12.6; SD = 1.06) were involved in this study. In order to investigate the variables considered in the study, the following measures were administered: the Deliberate Self-Harm Inventory exploring non-suicidal self-injurious behaviors; the Alexithymia Questionnaire for Children examining difficulty in identifying and describing feelings; the Inventory of Parent and Peer Attachment assessing the quality of parental and peer attachment; the Life Stressor Checklist-Revised outlining stressful/traumatic events and the Children's Depression Inventory evaluating suicidal ideation. Results: We found significantly positive relationships among difficulty in identifying and describing feelings, NSSI behaviors, stressful events, and suicidal ideation. Data indicated a significant negative association of difficulty in identifying and describing feelings with quality of attachment to parents and peers. Further findings highlighted that difficulty in identifying and describing feelings significantly mediated the effect of quality of attachment (parent and peer) on NSSI and suicidal ideation. Conclusion: The ability to identify and describing feelings is important to managing emotional expression and understanding the feelings of others, both crucial in attaining successful interpersonal relationships. Our data revealed that, while controlling for stressful life events, low levels of attachment may increase adolescents' difficulty in identifying and describing their own feelings, which in turn may increase the risk of both NSSI and suicidal ideation. PMID- 29593618 TI - Phonological Awareness and Rapid Automatized Naming Are Independent Phonological Competencies With Specific Impacts on Word Reading and Spelling: An Intervention Study. AB - Phonological awareness (PA) and rapid automatized naming (RAN) have been shown to be powerful predictors of reading achievement across many languages. However, literature remains unclear: (a) whether RAN is independent of PA, (b) about the specific influences of PA and RAN on reading and spelling, and (c) about the efficacy of a RAN intervention. This study aims to address these issues by means of an intervention design. Precisely, the objectives are (a) to determine whether training one competence involves or not an effect on the other, (b) to examine whether each intervention based on oral abilities (PA vs. RAN) could improve word reading and word spelling performances, and (c) to assess the efficacy of a RAN objects' intervention. Thirty-six French-speaking second graders, from two Belgian elementary schools, were divided into two groups, and received either a PA- or a RAN-objects' intervention. Twenty-five-minute lessons took place at school twice a week over a period of 2 months. Both groups were compared on multiple experimental measures (PA, RAN, word reading, and word spelling), before and immediately after the intervention, and 6 months later. Results showed specific efficacy of the two interventions, with participants trained in one ability outperforming those from the other group on this specific ability at post test. Moreover, the PA intervention revealed transfer effects on the sub-lexical processes of spelling, while the RAN intervention enhanced word reading speed. Finally, the results demonstrated the efficacy of a RAN-objects' intervention for the first time. These findings provide a new piece of evidence showing the independence of PA and RAN, each process influencing the acquisition of literacy skills in a different way. The efficacy and the specific transfer effects of both interventions open up new perspectives for prevention and targeted remediation of reading disabilities. PMID- 29593619 TI - Psychological Impact of Stalking on Male and Female Health Care Professional Victims of Stalking and Domestic Violence. AB - The aim of this work was to investigate stalking experiences in a sample of Health Care Professionals, or HCPs, who experienced domestic violence in their previous relationships with an intimate romantic or non-romantic who had become their stalkers. A comparison between males and females was made to highlight the differences among the genders. The findings showed that, for the most part, the victims experienced stalking by a stalker that was not of the same gender. Moreover, the nature of the relationship was romantic, for the most part, for both female and male subjects, suggesting that the principal motivation of stalking is the disruption of an intimate relationship. Regarding domestic violence, females described the phenomenon from a different perspective, indicating verbal, physical, and sexual abuse, while males indicated only verbal abuse. Females tended to amplify, more than the males, depression, and state and trait anxiety. Even if all symptoms were expressed in both females and males, the males exhibited a lack of confidence in their bodies, and the emotional literacy made the expression of distress more difficult. At the same time, the expression of anxiety presented in the women permitted them to become progressively less victimized over time; depression and anxiety allow the recognition of these symptoms as signs of distress and to intervene to reduce them. PMID- 29593620 TI - Planning Abilities in Bilingual and Monolingual Children: Role of Verbal Mediation. AB - We examined the role of verbal mediation in planning performance of English Spanish-speaking bilingual children and monolingual English-speaking children, between the ages of 9 and 12 years. To measure planning, children were administered the Tower of London (ToL) task. In a dual-task paradigm, children completed ToL problems under three conditions: with no secondary task (baseline), with articulatory suppression, and with non-verbal motor suppression. Analyses revealed generally shorter planning times for bilinguals than monolinguals but both groups performed similarly on number of moves and execution times. Additionally, bilingual children were more efficient at planning throughout the duration of the task while monolingual children showed significant gains with more practice. Children's planning times under articulatory suppression were significantly shorter than under motor suppression as well as the baseline condition, and there was no difference in planning times between monolingual and bilingual children during articulatory suppression. These results demonstrate that bilingualism influences performance on a complex EF measure like planning, and that these effects are not related to verbal mediation. PMID- 29593621 TI - Using Anchoring Vignettes to Adjust Self-Reported Personality: A Comparison Between Countries. AB - Data from self-report tools cannot be readily compared between cultures due to culturally specific ways of using a response scale. As such, anchoring vignettes have been proposed as a suitable methodology for correcting against this difference. We developed anchoring vignettes for the Big Five Inventory-44 (BFI 44) to supplement its Likert-type response options. Based on two samples (Rwanda: n = 423; Philippines: n = 143), we evaluated the psychometric properties of the measure both before and after applying the anchoring vignette adjustment. Results show that adjusted scores had better measurement properties, including improved reliability and a more orthogonal correlational structure, relative to scores based on the original Likert scale. Correlations of the Big Five Personality Factors with life satisfaction were essentially unchanged after the vignette adjustment while correlations with counterproductive were noticeably lower. Overall, these changed findings suggest that the use of anchoring vignette methodology improves the cross-cultural comparability of self-reported personality, a finding of potential interest to the field of global workforce research and development as well as educational policymakers. PMID- 29593622 TI - Measuring Responsibility and Cooperation in Learning Teams in the University Setting: Validation of a Questionnaire. AB - Cooperative learning are being used increasingly in the university classroom, in order to promote teamwork among students, improve performance and develop interpersonal competences. Responsibility and cooperation are two fundamental pillars of cooperative learning. Team members' responsibility is a necessary condition for the team's success in the assigned tasks. Students must be aware that they depend on each other and should make their maximum effort. On the other hand, in efficient groups, the members cooperate and pool their efforts to achieve the proposed goals. In this research, we propose to create a Questionnaire of Group Responsibility and Cooperation in Learning Teams (CRCG). Participants in this work were 375 students from the Faculty of Teacher Training of the University of Extremadura (Spain). The CRCG has very acceptable psychometric characteristics, good internal consistency, and temporal reliability. Moreover, structural equation analysis allowed us to verify that the latent variables in the two factors found are well defined and, therefore, their assessment is adequate. Besides, we found high significant correlations between the Learning Team Potency Questionnaire (CPEA) and the total score and the factors of the CRCG. This tool will evaluate cooperative skills and offer faculty information in order to prepare students for teamwork and conflict resolution. PMID- 29593623 TI - The Educational Situation Quality Model: Recent Advances. AB - The purpose of this work was to present an educational model developed in recent years entitled the "The Educational Situation Quality Model" (MOCSE, acronym in Spanish). MOCSE can be defined as an instructional model that simultaneously considers the teaching-learning process, where motivation plays a central role. It explains the functioning of an educational setting by organizing and relating the most important variables which, according to the literature, contribute to student learning. Besides being a conceptual framework, this model also provides a methodological procedure to guide research and to promote reflection in the classroom. It allows teachers to implement effective research-action programs to improve teacher-students satisfaction and learning outcomes in the classroom context. This work explains the model's characteristics and functioning, recent advances, and how teachers can use it in an educational setting with a specific subject. This proposal integrates approaches from several relevant psycho educational theories and introduces a new perspective into the existing literature that will allow researchers to make progress in studying educational setting functioning. The initial MOCSE configuration has been refined over time in accordance with the empirical results obtained from previous research, carried out within the MOCSE framework and with the subsequent reflections that derived from these results. Finally, the contribution of the model to improve learning outcomes and satisfaction, and its applicability in the classroom, are also discussed. PMID- 29593624 TI - Intraindividual Variability in Executive Function Performance in Healthy Adults: Cross-Sectional Analysis of the NAB Executive Functions Module. AB - The current study was aimed at investigating across-tasks intraindividual variability, also termed dispersion, in EF performance. The German adaptation of the Neuropsychological Assessment Battery (NAB) was used as a measure of EFs. Data of 444 participants aged 18-99 from six NAB Executive Functions Module subtests (i.e., Planning, Mazes, Letter Fluency, Judgment, Categories, and Word Generation) along with the NAB Total Index score as a measure of overall cognitive ability were analyzed. Maximum discrepancy (MD) was applied as a measure of dispersion. MD values ranged from 0.47 to 5.20 indicating substantial across-tasks dispersion in EF performance. Furthermore, dispersion moderately decreased with advancing age. Taking overall cognitive ability into account revealed that dispersion might be lower at older ages; especially, when associated with low overall ability levels. The dedifferentiation hypothesis offers a plausible explanation for these findings. That is, the cognitive profiles of older people might be less heterogenous than that of younger people, which may be due to age-related central nervous system constraints. PMID- 29593625 TI - The Potential and Challenges of Digital Well-Being Interventions: Positive Technology Research and Design in Light of the Bitter-Sweet Ambivalence of Change. AB - Along with the dissemination of technical assistance in nearly every part of life, there has been growing interest in the potential of technology to support well-being and human flourishing. "Positive technology" thereby takes the responsible role of a "digital coach," supporting people in achieving personal goals and behavior change. The design of such technology requires knowledge of different disciplines such as psychology, design and human-computer interaction. However, possible synergies are not yet used to full effect, and it needs common frameworks to support a more deliberate design of the "therapeutic interaction" mediated through technology. For positive technology design, positive psychology, and resource oriented approaches appear as particularly promising starting point. Besides a general fit of the basic theoretical conceptions of human change, many elements of established interventions could possibly be transferred to technology design. However, besides the power of focusing on the positive, another psychological aspect to consider are the bitter components inherent to change, such as the confrontation with a negative status quo, threat of self-esteem, and the effort required. The present research discusses the general potential and challenges within positive technology design from an interdisciplinary perspective with theoretical and practical contributions. Based on the bitter sweet ambivalence of change as present in many psychological approaches of motivation and behavior change, the bitter-sweet continuum serves as a proxy for the mixed emotions and cognitions related to change. An empirical investigation of those factors among 177 users of self-improvement technologies provides initial support for the usefulness of the bitter-sweet perspective in understanding change dynamics. In a next step, the bitter-sweet concept is transformed into different design strategies to support positive change. The present article aims to deepen the discussion about the responsible role of technology as a well-being enhancement tool and to provide a fruitful frame for different disciplines involved in positive technology. Two aspects are highlighted: First, investigating well-being technology as a form of "therapeutic interaction," focusing on the need for sensible design solutions in the emerging dialogue between technology and user. Second, a stronger consideration of the bitter-sweet ambivalence of change, utilizing (positive) psychology interventions to full effect. PMID- 29593627 TI - The Bright, the Dark, and the Blue Face of Narcissism: The Spectrum of Narcissism in Its Relations to the Metatraits of Personality, Self-Esteem, and the Nomological Network of Shyness, Loneliness, and Empathy. AB - Grandiose and vulnerable narcissism seem to be uncorrelated in empirical studies, yet they share at least some theoretical similarities. In the current study, we examine the relation between grandiose (conceptualized as admiration and rivalry) and vulnerable narcissism in the context of the Big Five personality traits and metatraits, self-esteem, and their nomological network. To this end, participants (N = 314) filled in a set of self-report measures via an online survey. Rivalry was positively linked with both admiration and vulnerable narcissism. We replicated the relations of admiration and rivalry with personality traits and metatraits-as well as extended existing knowledge by providing support for the theory that vulnerable narcissism is simultaneously negatively related to the Stability and Plasticity. Higher scores on vulnerable narcissism and rivalry predicted having fragile self-esteem, whereas high scores on admiration predicted having optimal self-esteem. The assumed relations with the nomological network were confirmed, i.e., vulnerable narcissism and admiration demonstrated a contradictory pattern of relation to shyness and loneliness, whilst rivalry predicted low empathy. Our results suggest that the rivalry is between vulnerable narcissism and admiration, which supports its localization in the self-importance dimension of the narcissism spectrum model. It was concluded that whereas admiration and rivalry represent the bright and dark face of narcissism, vulnerable narcissism represents its blue face. PMID- 29593626 TI - Negative Transfer Effects on L2 Word Order Processing. AB - Does first language (L1) word order affect the processing of non-canonical but grammatical syntactic structures in second language (L2) comprehension? In the present study, we test whether L1-Spanish speakers of L2-Basque process subject verb-object (SVO) and object-verb-subject (OVS) non-canonical word order sentences of Basque in the same way as Basque native speakers. Crucially, while OVS orders are non-canonical in both Spanish and Basque, SVO is non-canonical in Basque but is the canonical word order in Spanish. Our electrophysiological results showed that the characteristics of L1 affect the processing of the L2 even at highly proficient and early-acquired bilingual populations. Specifically, in the non-native group, we observed a left anterior negativity-like component when comparing S and O at sentence initial position and a P600 when comparing those elements at sentence final position. Those results are similar of those reported by Casado et al. (2005) for native speakers of Spanish indicating that L2-Basque speakers rely in their L1-Spanish when processing SVO-OVS word order sentences. Our results favored the competition model (MacWhinney, 1997). PMID- 29593628 TI - Gray Matter and White Matter Abnormalities in Temporal Lobe Epilepsy Patients with and without Hippocampal Sclerosis. AB - The presentation and distribution of gray matter (GM) and white matter (WM) abnormalities in temporal lobe epilepsy (TLE) have been widely studied. Here, we investigated the GM and WM abnormalities in TLE patients with and without hippocampal sclerosis (HS) in five groups of participants: healthy controls (HCs) (n = 28), right TLE patients with HS (n = 26), right TLE patients without HS (n = 30), left TLE patients with HS (n = 25), and left TLE patients without HS (n = 27). We performed a flexible factorial statistical test in a whole-brain voxel based morphometry analysis to identify significant GM and WM abnormalities and analysis of variance of hippocampal and amygdala regions among the five groups using the FreeSurfer procedure. Furthermore, we conducted multiple regression analysis to assess regional GM and WM changes with disease duration. We observed significant ipsilateral mesiotemporal GM and WM volume reductions in TLE patients with HS compared with HCs. We also observed a slight GM amygdala swelling in right TLE patients without HS. The regression analysis revealed significant negative GM and WM changes with disease duration specifically in left TLE patients with HS. The observed GM and WM abnormalities may contribute to our understanding of the root of epilepsy mechanisms. PMID- 29593629 TI - Risk of Microangiopathy in Patients with Epilepsy under Long-term Antiepileptic Drug Therapy. AB - Background: Long-term antiepileptic drug (AED) therapy is considered a risk factor of atherosclerosis. Furthermore, the duration of therapy contributes to acceleration of large-vessel atherosclerosis. Therefore, in this study, we tested the hypothesis that long-term AED therapy plays a crucial role in the pathogenesis of microangiopathy in patients with epilepsy. Methods: We recruited 120 patients with epilepsy (age, 18-60 years) and 40 healthy controls. Optical coherence tomography (OCT) was used to measure the central macular thickness and diameters of the retinal artery and vein to evaluate atherosclerotic retinopathy; microalbumin and creatinine levels in urine were assessed to evaluate atherosclerotic nephropathy. In addition, high-sensitivity C-reactive protein (hs CRP), lipid profiles, homocysteine, folate, uric acid, and body mass index were determined. Results: The ratio of urine albumin to creatine and OCT findings showed that patients with epilepsy had higher abnormal microalbuminuria and narrowing retinal vein diameters, respectively. Multiple linear regression analysis showed that increased triglyceride and hs-CRP levels might contribute to microalbuminuria. In addition, serum creatinine, duration of AED therapy, enzyme inducing AED therapy, and duration of enzyme-inducing AED therapy were candidate risk factors for retinal vein narrowing. Conclusion: Patients with epilepsy are at a higher risk for microangiopathy presented as retinopathy and nephropathy. Long-term AED therapy, particularly with enzyme-inducing AEDs; high triglyceride levels, and inflammatory processes play an important role in the development of microangiopathy in patients with epilepsy. PMID- 29593630 TI - Parkinson's Disease Dementia and Dementia with Lewy Bodies Have Similar Neuropsychological Profiles. AB - Parkinson's disease dementia (PDD) and dementia with Lewy bodies (DLB) are common causes of dementia worldwide. Although considered separate entities based on the relative temporal onset of motor symptoms vs. diagnosis of dementia, it is unknown if these diseases truly have distinct cognitive profiles. We hypothesized that patients divided into PDD and DLB categories strictly by temporal criteria would have different neuropsychological profiles. We investigated this question via neuropsychological testing of PDD and DLB patients at the University of Iowa. We performed retrospective chart analysis and review of neuropsychological testing of clinically diagnosed patients with PDD or DLB, who had presented to University of Iowa's dementia and movement disorder clinics. Forty-seven patients diagnosed by the treating neurologist as PDD or DLB were included. Neuropsychological performance was compared between groups, and as a function of the relative timing of the motor diagnosis vs. diagnosis of dementia. We found that both PDD and DLB patients showed severe deficits in executive function, visual-spatial processing, and verbal learning. However, we found no significant differences in neuropsychological performance between groups, and neuropsychological performance could not reliably account for the relative timing of motor diagnosis vs. diagnosis of dementia. Our data support the idea that DLB and PDD are on a neuropsychological spectrum. PMID- 29593631 TI - Acute Hemorrhagic Encephalitis Responding to Combined Decompressive Craniectomy, Intravenous Immunoglobulin, and Corticosteroid Therapies: Association with Novel RANBP2 Variant. AB - Background: Acute hemorrhagic encephalomyelitis (AHEM) is considered as a rare form of acute disseminated encephalomyelitis characterized by fulminant encephalopathy with hemorrhagic necrosis and most often fatal outcome. Objective: To report the association with Ran Binding Protein (RANBP2) gene variant and the response to decompressive craniectomy and high-dose intravenous methylprednisolone (IVMP) in life-threatening AHEM. Design: Single case study. Case report: A 6-year-old girl known to have sickle cell disease (SCD) presented an acquired demyelinating syndrome (ADS) with diplopia due to sudden unilateral fourth nerve palsy. She received five pulses of IVMP (30 mg/kg/day). Two weeks after steroid weaning, she developed right hemiplegia and coma. Brain magnetic resonance imaging showed a left frontal necrotico-hemorrhagic lesion and new multifocal areas of demyelination. She underwent decompressive craniotomy and evacuation of an ongoing left frontoparietal hemorrhage. Comprehensive investigations ruled out vascular and infectious process. The neurological deterioration stopped concomitantly with combined neurosurgical drainage of the hematoma, decompressive craniotomy, IVMP, and intravenous immunoglobulins (IVIG). She developed during the following months Crohn disease and sclerosing cholangitis. After 2-year follow-up, there was no new neurological manifestation. The patient still suffered right hemiplegia and aphasia, but was able to walk. Cognitive/behavioral abilities significantly recovered. A heterozygous novel rare missense variant (c.4993A>G, p.Lys1665Glu) was identified in RANBP2, a gene associated with acute necrotizing encephalopathy. RANBP2 is a protein playing an important role in the energy homeostasis of neuronal cells. Conclusion: In any ADS occurring in the context of SCD and/or autoimmune condition, we recommend to slowly wean steroids and to closely monitor the patient after weaning to quickly treat any recurrence of neurological symptom with IVMP. This case report, in addition to others, stresses the likely efficacy of combined craniotomy, IVIG, and IVMP treatments in AHEM. RANBP2 mutations may sensitize the brain to inflammation and predispose to AHEM. PMID- 29593632 TI - Stroke-Related Changes in the Complexity of Muscle Activation during Obstacle Crossing Using Fuzzy Approximate Entropy Analysis. AB - This study investigated the complexity of the electromyography (EMG) of lower limb muscles when performing obstacle crossing tasks at different heights in poststroke subjects versus healthy controls. Five poststroke subjects and eight healthy controls were recruited to perform different obstacle crossing tasks at various heights (randomly set at 10, 20, and 30% of the leg's length). EMG signals were recorded from bilateral biceps femoris (BF), rectus femoris (RF), medial gastrocnemius, and tibialis anterior during obstacle crossing task. The fuzzy approximate entropy (fApEn) approach was used to analyze the complexity of the EMG signals. The fApEn values were significantly smaller in the RF of the trailing limb during the swing phase in poststroke subjects than healthy controls (p < 0.05), which may be an indication of smaller number and less frequent firing rates of the motor units. However, during the swing phase, there were non significant increases in the fApEn values of BF and RF in the trailing limb of the stroke group compared with those of healthy controls, resulting in a coping strategy when facing challenging tasks. The fApEn values that increased with height were found in the BF of the leading limb during the stance phase and in the RF of the trailing limb during the swing phase (p < 0.05). The reason for this may have been a larger muscle activation associated with the increase in obstacle height. This study demonstrated a suitable and non-invasive method to evaluate muscle function after a stroke. PMID- 29593633 TI - Quantitative Limbic System Mapping of Main Cognitive Domains in Multiple Sclerosis. AB - Background and objective: Cognitive impairment (CI) is common in multiple sclerosis (MS), but underlying mechanisms and their imaging correlates are not completely understood. The gray and white matter structures of the limbic system (LS) play crucial roles in different aspects of cognition. To investigate their role in MS related CI, and since a detailed evaluations are lacking in the literature, we used a comprehensive neuroimaging approach to evaluate CI's correlations with the main components of the LS. Methods: Ten non-cognitively impaired MS patients and 30 MS patients with diagnosed CI, who underwent a comprehensive neuropsychological evaluation were included in the analysis. Microstructural integrity, volumetry of main limbic gray and white matter structures and cortical thickness were assessed for associations with CI. Results: Fornix and cingulum/cingulate cortices were found to be the strongest correlates of CI in MS. As expected, LS' gray and white matter structures were involved in various cognitive functions. Uncinate fasciculi showed significant correlation with verbal and visuospatial learning and memory, phonemic and semantic fluency; hippocampi with visuospatial skills, phonemic and semantic fluency, executive functions, and processing speed; thalami with verbal learning, visuospatial skills, semantic fluency; and amygdala with verbal recognition discrimination. Conclusion: This comprehensive neuroimaging approach elucidated the role of the main limbic structures in cognitive functions associated with MS related CI. PMID- 29593634 TI - Acute Ischemic Stroke Hospital Admissions, Treatment, and Outcomes in Poland in 2009-2013. AB - Introduction: Ischemic stroke (IS) still constitutes a serious problem for public health worldwide. The data on its burden in Poland before 2009 is limited and came only from a few metropolitan areas. The aims of the study were: To assess temporal trends in the hospital admissions, treatment, and outcomes of IS in Poland in 2009-2013, to identify risk factors for IS mortality and to compare the results with other countries. Methods: The data from the Polish Stroke Registry were analyzed. The data concerned all subjects hospitalized due to IS (classified according to the ICD10 classification as I63.0-I63.9) as primary diagnosis in Poland in 2009-2013. Temporal trends in treatment and outcome were analyzed. Hospital admissions rates as well as case fatality and 12-month mortality rates were calculated. Results: Altogether, 360,556 patients (47.5% of males) were hospitalized due to IS in Poland in 2009-2013. The median of age was 75 years, IQR 18 (Women 78, IQR 14 vs. Men 70, IQR 17; p < 0.001). The hospital admissions age-standardized annual rate for IS in Poland in 2013 was 8% lower than in 2009 (169 vs. 157/100,000; p for trend < 0.001). In-hospital case fatality has slightly decreased (from 13.6% in 2009 to 12.9% in 2013; p for trend < 0.001). One-year posthospital mortality rate has not changed (19.3% in 2009 and 2013). The percentage of IS subjects treated with intravenous thrombolysis was low but increased from 1.7% in 2009 to 6.3% in 2013 (p for trend <0.001). Conclusion: Since 2009, Poland has had national epidemiological data on the hospital admissions, treatment, and outcomes in IS. The data indicate a slow improvement of in-hospital survival and suggest the need for better stroke prevention and further dissemination of reperfusion therapy. PMID- 29593635 TI - Postoperative Tinnitus After Vestibular Schwannoma Surgery Depends on Preoperative Tinnitus and Both Pre- and Postoperative Hearing Function. AB - Objective: Tinnitus is one of the most common symptoms before and/or after the surgical removal of a vestibular schwannoma (VS) affecting almost half of the patients. Although there is increasing evidence for the association of hearing impairment and VS-associated tinnitus, the effect of hearing deterioration due to surgery and its relation to the postoperative tinnitus (postTN) is poorly investigated. This knowledge, however, might (i) enlighten the pathophysiology of VS-associated tinnitus (i.e., peripheral or central origin) and (ii) improve preoperative patient counseling. The aim of this study was to understand the predisposition factors for a postTN in relation to hearing outcome after surgery. Methods: This retrospective study analyzed the presence of tinnitus in 208 patients with unilateral VS before and after surgical removal. A binomial logistic regression was performed to ascertain the effect of pre- and postoperative hearing as well as age, gender, tumor side, and size, and intraoperative cochlear nerve resection (CNR) on the likelihood of postoperative VS-associated tinnitus. Results: Preoperative tinnitus was the strongest predictor of postTN. In addition, deterioration of functional hearing was increasing, while functional deafferentation (i.e., postoperative hearing loss) of non-functional hearing was reducing the risk of postTN. At the same time, patients with no preoperative tinnitus but complete hearing loss had the lowest risk to suffer from postTN. Patient age, gender, tumor side, and size as well as CNR played a subordinate role. Conclusion: While the presence of preoperative tinnitus was the strongest predictor of postTN, there is a distinct relationship between hearing outcome and postTN depending on the preoperative situation. Functional or anatomical deafferentation due to surgical tumor removal does not prevent postTN per se. PMID- 29593636 TI - Combined Treatment With Dichloroacetic Acid and Pyruvate Reduces Hippocampal Neuronal Death After Transient Cerebral Ischemia. AB - Transient cerebral ischemia (TCI) occurs when blood flow to the brain is ceased or dramatically reduced. TCI causes energy depletion and oxidative stress, which leads to neuronal death and cognitive impairment. Dichloroacetic acid (DCA) acts as an inhibitor of pyruvate dehydrogenase kinase (PDK). Additionally, DCA is known to increase mitochondrial pyruvate uptake and promotes glucose oxidation during glycolysis, thus enhancing pyruvate dehydrogenase (PDH) activity. In this study, we investigated whether the inhibition of PDK activity by DCA, which increases the rate of pyruvate conversion to adenosine triphosphate (ATP), prevents ischemia-induced neuronal death. We used a rat model of TCI, which was induced by common carotid artery occlusion and hypovolemia for 7 min while monitoring the electroencephalography for sustained isoelectric potential. Male Sprague-Dawley rats were given an intraperitoneal injection of DCA (100 mg/kg) with pyruvate (50 mg/kg) once per day for 2 days after insult. The vehicle, DCA only or pyruvate on rats was injected on the same schedule. Our study demonstrated that the combined administration of DCA with pyruvate significantly decreased neuronal death, oxidative stress, microglia activation when compared with DCA, or pyruvate injection alone. These findings suggest that the administration of DCA with pyruvate may enhance essential metabolic processes, which in turn promotes the regenerative capacity of the post-ischemic brain. PMID- 29593638 TI - Tourette Syndrome: A Mini-Review. AB - The purpose of this mini-review is to provide the latest information on epidemiology, pathophysiology, diagnosis, and treatment of Tourette syndrome (TS). The authors conducted a literature search of available sources describing the issue of tic disorders with special focus on TS and made a comparison and evaluation of relevant findings. The results of this mini-review indicate that TS is a complex disorder, which has a significant impact on the quality of life of both the patients and his/her family. Therefore, early and proper diagnosis and treatment are necessary in order to reduce or even eliminate both symptoms and social burden of the patient. This requires a multidisciplinary management approach in order to meet the patients' special needs. Future research should focus on neuroimaging, new neurotransmitter targets, in functional neurosurgery, as well as the effect of non-pharmacological psychotherapies for these people. PMID- 29593639 TI - Step by Step: Kinematics of the Reciprocal Trail Making Task Predict Slowness of Activities of Daily Living Performance in Alzheimer's Disease. AB - Dementia impairs the ability to perform everyday activities. Reduced motor capacity and executive functions as well as loss of memory function and forms of apraxia and action disorganization syndrome can be reasons for such impairments. In this study, an analysis of the hand trajectories during the sequential movements in an adapted version of the trail making task, the reciprocal trail making task (RTMT), was used to predict performance in activities of daily living (ADL) of patients suffering from mild cognitive impairment and dementia. 1 patient with dementia of the Alzheimer's type and 15 healthy, age-matched adults were tested in the standardized ADL of tea making and document filing. The characteristics of the kinematic performance in the RTMT were assessed, and models of multiple linear regression were computed to predict the durations of the ADL. Patients showed increased trial durations (TDs) in the ADL (Cohen's d: tea making 1.64, document filing 1.25). Parameters and explained variability differed across patients and control as well as between different activities. The models for the patient sample were stronger and particularly high for the document filing task for which kinematics explained 71% of the variance ([Formula: see text]: tea making 0.62, document filing 0.71; both tasks combined patients 0.55, controls 0.25). The most relevant factors for the models were the TD and a parameter characterizing movement fluency and variability ("movement harmonicity") in the RTMT. The models of multiple linear regression suggested that the patients' activity of daily living performance was limited by cognitive demands, namely, identifying the varying targets during sequencing and the healthy controls' performance by their motor capacity. Such models could be used to estimate the severity of ADL impairments in patients. PMID- 29593637 TI - Structural and Functional Brain Patterns of Non-Motor Syndromes in Parkinson's Disease. AB - Parkinson's disease (PD) is a common, progressive and multisystem neurodegenerative disorder characterized by motor and non-motor symptoms. Advanced magnetic resonance imaging, positron emission tomography, and functional magnetic resonance imaging can render the view toward understanding the neural basis of these non-motor syndromes, as they help to understand the underlying pathophysiological abnormalities. This review provides an up-to-date description of structural and functional brain alterations in patients with PD with cognitive deficits, visual hallucinations, fatigue, impulsive behavior disorders, sleep disorders, and pain. PMID- 29593640 TI - Vestibular Dysfunction in Wernicke's Encephalopathy: Predominant Impairment of the Horizontal Semicircular Canals. AB - Background: Wernicke's encephalopathy (WE), a metabolic disorder due to thiamine deficiency, manifests with various neurological symptoms and signs. It has been known as a cause of vestibular dysfunction. Preliminary reports have proposed predominant involvement of the horizontal semicircular canals (HSCs). Objective: To better characterize the pattern of vestibular impairment in patients with WE using quantitative video head-impulse testing and to review the literature regarding this topic. Method: From January 2014 to December 2016, we retrospectively enrolled five cases of WE that received quantitative video-head impulse testing (vHIT). We retrieved the clinical features from the medical records and reviewed quantitative head-impulse testing (qHIT) and caloric irrigation. Based on the gain and the number of corrective saccades, the function (normal vs. impaired) of each semicircular canal was rated. In addition, we conducted a MEDLINE and EMBASE search to identify other published cases of WE that had received qHIT. Neuro-otologic and neuro-ophthalmologic findings and vestibular testing results were extracted. Results: A total of 17 patients (own series = 5; published cases = 12) aged 54.6 +/- 11 years were included. Key neurologic findings were ataxia of stance and gait (13/13, 100%), spontaneous nystagmus (7/14, 50%), gaze-evoked nystagmus (GEN) (17/17, 100%), positive bedside head-impulse testing for the horizontal canals (16/17, 94%), and memory impairment and mental changes (6/11, 54.5%). Regarding vestibular testing, qHIT (either video based or search-coil based) documented selective bilateral horizontal canal dysfunction with normal or minimal vertical canal impairment (14/14, 100%). On caloric irrigation, bilateral horizontal canal paresis was noted in most cases (10/11, 91%). Conclusion: In WE, signs of both peripheral and central vestibular dysfunction (i.e., GEN, ataxia of stance and gait, abnormal head-impulse testing) were common. Selective or predominant impairment of the HSCs seems to be the most common finding of WE likely related to enhanced vulnerability of the medial vestibular nuclei neurons to thiamine deficiency. Quantitative vHIT of all six semicircular canals is therefore a useful tool for the diagnosis and should be applied in all patients with suspected WE. PMID- 29593641 TI - Localization of Epileptogenic Zone With the Correction of Pathological Networks. AB - Patients with focal drug-resistant epilepsy are potential candidates for surgery. Stereo-electroencephalograph (SEEG) is often considered as the "gold standard" to identify the epileptogenic zone (EZ) that accounts for the onset and propagation of epileptiform discharges. However, visual analysis of SEEG still prevails in clinical practice. In addition, epilepsy is increasingly understood to be the result of network disorder, but the specific organization of the epileptic network is still unclear. Therefore, it is necessary to quantitatively localize the EZ and investigate the nature of epileptogenic networks. In this study, intracranial recordings from 10 patients were analyzed through adaptive directed transfer function, and the out-degree of effective network was selected as the principal indicator to localize the epileptogenic area. Furthermore, a coupled neuronal population model was used to qualitatively simulate electrical activity in the brain. By removing individual populations, virtual surgery adjusting the network organization could be performed. Results suggested that the accuracy and detection rate of the EZ localization were 82.86 and 85.29%, respectively. In addition, the same stage shared a relatively stable connectivity pattern, while the patterns changed with transition to different processes. Meanwhile, eight cases of simulations indicated that networks in the ictal stage were more likely to generate rhythmic spikes. This indicated the existence of epileptogenic networks, which could enhance local excitability and facilitate synchronization. The removal of the EZ could correct these pathological networks and reduce the amount of spikes by at least 75%. This might be one reason why accurate resection could reduce or even suppress seizures. This study provides novel insights into epilepsy and surgical treatments from the network perspective. PMID- 29593642 TI - Microsaccade Characteristics in Neurological and Ophthalmic Disease. AB - Microsaccade research has recently reached a critical mass of studies that allows, for the first time, a comprehensive review of how microsaccadic dynamics change in neurological and ophthalmic disease. We discuss the various pathological conditions that affect microsaccades, their impact on microsaccadic and other fixational eye movement dynamics, and the incipient studies that point to microsaccadic features as potential indicators of differential and early diagnoses of multiple clinical conditions, from movement disorders to attention deficit hyperactivity disorder to amblyopia. We propose that the objective assessment of fixational eye movement parameters may help refine differential diagnostics in neurological disease and assist in the evaluation of ongoing therapy regimes. In addition, determining the effects of ophthalmic disease on fixational eye movement features may help evaluate visual impairment in an objective manner, particularly in young patients or those experiencing communication difficulties. PMID- 29593643 TI - Spontaneous Nystagmus in the Dark in an Infantile Nystagmus Patient May Represent Negative Optokinetic Afternystagmus. AB - Abnormal projection of the optic nerves to the wrong cerebral hemisphere transforms the optokinetic system from its usual negative feedback loop to a positive feedback loop with characteristic ocular motor instabilities including directional reversal of the optokinetic nystagmus (OKN) and spontaneous nystagmus, which are common features of infantile nystagmus syndrome (INS). Visual input plays a critical role in INS linked to an underlying optic nerve misprojection such as that often seen in albinism. However, spontaneous nystagmus often continues in darkness, making the visual, sensory-driven etiology questionable. We propose that sensorimotor adaptation during the constant nystagmus of patients in the light could account for continuing nystagmus in the dark. The OKN is a stereotyped reflexive eye movement in response to motion in the surround and serves to stabilize the visual image on the retina, allowing high resolution vision. Robust negative optokinetic afternystagmus (negative OKAN), referring to the continuous nystagmus in the dark with opposite beating direction of the preceding OKN, has been identified in various non-foveated animals. In humans, a robust afternystagmus in the same direction as previous smooth-pursuit movements (the eye's continuous tracking and foveation of a moving target) induced by visual stimuli has been known to commonly mask negative OKAN. Some INS patients are often associated with ocular hypopigmentation, foveal hypoplasia, and compromised smooth pursuit. We identified an INS case with negative OKAN in the dark, in contrast to the positive afternystagmus in healthy subjects. We hypothesize that spontaneous nystagmus in the dark in INS patients may be attributable to sensory adaptation in the optokinetic system after a sustained period of spontaneous nystagmus with directional visual input in light. PMID- 29593644 TI - Autonomic Neuropathy-a Prospective Cohort Study of Symptoms and E/I Ratio in Normal Glucose Tolerance, Impaired Glucose Tolerance, and Type 2 Diabetes. AB - Background: Autonomic neuropathy in diabetes, in addition to causing a range of symptoms originating from the autonomic nervous system, may increase cardiovascular morbidity. Our aim was to study the progression of autonomic neuropathy, based on symptom score and evaluation of an autonomic test, in persons with normal and impaired glucose tolerance and in patients with type 2 diabetes (T2D). Methods: Participants were recruited in 2003/2004 with a follow up in 2014. The participants' glucose tolerance was categorized using oral glucose tolerance tests. Symptoms were evaluated using an autonomic symptom score (ASS), ECG was used to test cardiac autonomic function based on the expiration/inspiration ratio (E/I ratio), and blood samples were taken on both occasions. Results: ASSs were higher at follow-up in the T2D patients than in the normal glucose tolerance group (mean 1.21 +/- 1.30 vs. 0.79 +/- 0.7; p < 0.05). E/I ratio did not deteriorate more than could be expected as an aging effect in well-controlled T2D. No relationship was found between E/I ratio and HbA1c or ASS. Conclusion: The presence of autonomic symptoms increased over time in T2D patients, but the symptoms did not correlate with the E/I ratio in this metabolically well-controlled cohort. ASSs can be a useful clinical tool when assessing the progression of autonomic dysfunction in patients with abnormal glucose metabolism.

PMID- 29593647 TI - Adiponectin, Leptin, IGF-1, and Tumor Necrosis Factor Alpha As Potential Serum Biomarkers for Non-Invasive Diagnosis of Colorectal Adenoma in African Americans. AB - The potential role of adiponectin, leptin, IGF-1, and tumor necrosis factor alpha (TNF-alpha) as biomarkers in colorectal adenoma is not clear. Therefore, we aimed to investigate the blood serum levels of these biomarkers in colorectal adenoma. The case-control study consisted of serum from 180 African American patients with colon adenoma (cases) and 198 healthy African Americans (controls) at Howard University Hospital. We used ELISA for adiponectin, leptin, IGF-1, and TNF-alpha detection and quantification. Statistical analysis was performed by t-test and multivariate logistic regression. The respective differences in median leptin, adiponectin, IGF-1, and TNF-alpha levels between control and case groups (13.9 vs. 16.4), (11.3 vs. 46.0), (4.5 vs. 12.9), and (71.4 vs. 130.8) were statistically significant (P < 0.05). In a multivariate model, the odds ratio for adiponectin, TNF-alpha, and IGF-1 were 2.0 (95% CI = 1.6-2.5; P < 0.001), 1.5 (95% CI = 1.5(1.1-2.0); P = 0.004), and 1.6 (95% CI = 1.3-2.0; P < 0.001), respectively. There was a positive correlation between serum adiponectin and IGF 1 concentrations with age (r = 0.17, P < 0.001 and r = 0.13, P = 0.009), TNF alpha, IGF-1, and leptin concentration with body mass index (BMI) (r = 0.44, P < 0.001; r = 0.11, P = 0.03; and r = 0.48, P < 0.001), respectively. Also, there was a negative correlation between adiponectin and leptin concentrations with BMI (r = -0.40, P < 0.001), respectively. These data support the hypothesis that adiponectin, IGF-1, and TNF-alpha high levels correlate with higher risk of colon adenoma and can thus be used for colorectal adenomas risk assessment. PMID- 29593646 TI - An Approach to Greater Specificity for Glucocorticoids. AB - Glucocorticoid steroids are among the most prescribed drugs each year. Nonetheless, the many undesirable side effects, and lack of selectivity, restrict their greater usage. Research to increase glucocorticoid specificity has spanned many years. These efforts have been hampered by the ability of glucocorticoids to both induce and repress gene transcription and also by the lack of success in defining any predictable properties that control glucocorticoid specificity. Correlations of transcriptional specificity have been observed with changes in steroid structure, receptor and chromatin conformation, DNA sequence for receptor binding, and associated cofactors. However, none of these studies have progressed to the point of being able to offer guidance for increased specificity. We summarize here a mathematical theory that allows a novel and quantifiable approach to increase selectivity. The theory applies to all three major actions of glucocorticoid receptors: induction by agonists, induction by antagonists, and repression by agonists. Simple graphical analysis of competition assays involving any two factors (steroid, chemical, peptide, protein, DNA, etc.) yields information (1) about the kinetically described mechanism of action for each factor at that step where the factor acts in the overall reaction sequence and (2) about the relative position of that step where each factor acts. These two pieces of information uniquely provide direction for increasing the specificity of glucocorticoid action. Consideration of all three modes of action indicate that the most promising approach for increased specificity is to vary the concentrations of those cofactors/pharmaceuticals that act closest to the observed end point. The potential for selectivity is even greater when varying cofactors/pharmaceuticals in conjunction with a select class of antagonists. PMID- 29593648 TI - Appropriate Frequency and Interval of Neck Ultrasonography Surveillance during the First 10 Years after Total Thyroidectomy in Patients with Papillary Thyroid Carcinoma. AB - Background: No previous study has employed the frequency and interval of follow up ultrasonography (US) during the first 10 years after total thyroidectomy in patients with papillary thyroid carcinoma (PTC). The aim of this study was to determine the appropriate frequency and interval of follow-up US during the first 10 years in patients who have undergone total thyroidectomy for PTC. Methods: Two hundred seventy-two patients underwent total thyroidectomy for PTC at our institution from January 2006 to December 2007. Nineteen patients were excluded because of lack of US follow-up data for the neck. Follow-up US was performed by one of two radiologists in all patients. Tumor recurrence/persistence was confirmed by histopathology. Results: The mean interval between surgery and the final follow-up US examination was 79.0 months, and the mean number of follow-up US sessions was 5.9 in the 253 evaluable patients. Eleven patients (4.3%) developed tumor recurrence/persistence, which was detected on follow-up US within 5 years after total thyroidectomy in all cases. T and N stages were independently associated with tumor recurrence/persistence. The interval between surgery and first suspicion of tumor recurrence/persistence on follow-up US was <=12 months in six patients and 20, 35, 41, 53, and 60 months in the remaining five patients. Conclusion: For detection of tumor recurrence/persistence after total thyroidectomy in patients with PTC, one or two sessions of follow-up US during the first 2 years, depending on T and N stages and one session of follow-up US in every second year during the following 8 years may be appropriate. PMID- 29593650 TI - Hypophysitis following Treatment with Ustekinumab: Radiological and Pathological Findings. AB - Context: Ustekinumab is a human IgG1 monoclonal antibody that targets interleukin (IL)-12 and IL-23, which may be useful in the treatment of autoimmune conditions such as psoriasis, psoriatic arthritis, and Crohn's disease. Hypophysitis is an immune-derived inflammatory condition of the pituitary gland that may lead to pituitary dysfunction. With the increasing use of immunotherapy, it is possible that this and other new immune-related adverse events (IRAEs) arise, although the mechanisms involved are still incompletely defined. Case description: A 35-year old male, with a previous history of severe plaque-psoriasis who had started treatment with ustekinumab 4 months before, complained of progressive and persistent headache. Brain magnetic resonance imaging (MRI) was unremarkable. One year later, a new MRI was performed due to headache persistence, which revealed a homogenous and diffuse pituitary enlargement, with suprasellar extension and optic chiasm involvement, blurring of the pituitary stalk, absence of clear differentiation between the anterior and posterior lobes, and no signs of hemorrhage or adenomas. Endocrine evaluation was consistent with panhypopituitarism. Work-up of infiltrative and infectious diseases was negative. Follow-up MRI revealed an increase in the pituitary enlargement and transsphenoidal surgery was performed. Pathological findings revealed an intense fibrosis and a chronic inflammatory infiltrate, but no evidence of adenoma, granuloma, or acid fast bacilli. Immunohistochemical staining showed a combined T cell (CD3+, CD4+) and B-cell (CD19+, CD20+) phenotype. Conclusion: We suggest a novel IRAE of ustekinumab, with full radiological and immunopathological iconography, which may be mediated by the complex interaction between different immunological processes. PMID- 29593649 TI - Insulin-Like Growth Factor-Binding Proteins of Teleost Fishes. AB - The insulin-like growth factor (Igf) binding protein (Igfbp) family has a broad range of physiological functions and a fascinating evolutionary history. This review focuses on the Igfbps of teleost fishes, where genome duplication events have diversified gene repertoire, function, and physiological regulation-with six core Igfbps expanded into a family of over twenty genes in some lineages. In addition to briefly summarizing the current state of knowledge on teleost Igfbp evolution, function, and expression-level regulation, we highlight gaps in our understanding and promising areas for future work. PMID- 29593651 TI - Distinct Shift in Beta-Cell Glutaredoxin 5 Expression Is Mediated by Hypoxia and Lipotoxicity Both In Vivo and In Vitro. AB - Histomorphological and functional alterations in pancreatic islet composition directly correlate with hyperglycemia severity. Progressive deterioration of metabolic control in subjects suffering from type 2 diabetes is predominantly caused by impaired beta-cell functionality. The glutaredoxin system is supposed to wield protective properties for beta-cells. Therefore, we sought to identify a correlation between the structural changes observed in diabetic pancreatic islets with altered glutaredoxin 5 expression, in order to determine an underlying mechanism of beta-cell impairment. Islets of db/db mice presenting with uncontrolled diabetes were assessed in terms of morphological structure and insulin, glucagon, and glutaredoxin 5 expression. MIN6 cell function and glutaredoxin 5 expression were analyzed after exposure to oleic acid and hypoxia. Islets of diabese mice were marked by typical remodeling and distinct reduction of, and shifts, in localization of glutaredoxin 5-positive cells. These islets featured decreased glutaredoxin 5 as well as insulin and glucagon content. In beta-cell culture, glutaredoxin 5 protein and mRNA expression were decreased by hypoxia and oleic acid but not by leptin treatment. Our study demonstrates that glutaredoxin 5 expression patterns are distinctively altered in islets of rodents presenting with uncontrolled diabesity. In vitro, reduction of islet-cell glutaredoxin 5 expression was mediated by hypoxia and oleic acid. Thus, glutaredoxin 5-deficiency in islets during diabetes may be caused by lipotoxicity and hypoxia. PMID- 29593652 TI - 11beta-HSD Types 1 and 2 in the Songbird Brain. AB - Glucocorticoid (GC) hormones act on the brain to regulate diverse functions, from behavior and homeostasis to the activity of the hypothalamic-pituitary-adrenal axis. Local regeneration and metabolism of GCs can occur in target tissues through the actions of the 11beta-hydroxysteroid dehydrogenases [11 beta hydroxysteroid dehydrogenase type 1 (11beta-HSD1) and 11 beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2), respectively] to regulate access to GC receptors. Songbirds have become especially important model organisms for studies of stress hormone action; however, there has been little focus on neural GC metabolism. Therefore, we tested the hypothesis that 11beta-HSD1 and 11beta-HSD2 are expressed in GC-sensitive regions of the songbird brain. Localization of 11beta-HSD expression in these regions could provide precise temporal and spatial control over GC actions. We quantified GC sensitivity in zebra finch (Taeniopygia guttata) brain by measuring glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) expression across six regions, followed by quantification of 11beta HSD1 and 11beta-HSD2 expression. We detected GR, MR, and 11beta-HSD2 mRNA expression throughout the adult brain. Whereas 11beta-HSD1 expression was undetectable in the adult brain, we detected low levels of expression in the brain of developing finches. Across several adult brain regions, expression of 11beta-HSD2 covaried with GR and MR, with the exception of the cerebellum and hippocampus. It is possible that receptors in these latter two regions require direct access to systemic GC levels. Overall, these results suggest that 11beta HSD2 expression protects the adult songbird brain by rapid metabolism of GCs in a context and region-specific manner. PMID- 29593653 TI - Identification of Metabolomic Biomarkers for Endometrial Cancer and Its Recurrence after Surgery in Postmenopausal Women. AB - Endometrial cancer (EC) is the most frequent gynecological cancer in developed countries. Most EC occurs after menopause and is diagnosed as endometrioid (type I) carcinomas, which exhibit a favorable prognosis. In contrast, non-endometrioid (type II) carcinomas such as serous tumors have a poor prognosis. Our goal was to identify novel blood-based markers associated with EC subtypes and recurrence after surgery in postmenopausal women. Using mass spectrometry-based untargeted metabolomics, we examined preoperative serum metabolites among control women (n = 18) and those with non-recurrent (NR) and recurrent (R) cases of type I endometrioid (n = 24) and type II serous (n = 12) carcinomas. R and NR cases were similar with respect to pathological characteristics, body mass index, and age. A total of 1,592 compounds were analyzed including 14 different lipid classes. When we compared EC cases with controls, 137 metabolites were significantly different. A combination of spermine and isovalerate resulted in an age-adjusted area under the receiver-operating characteristic curve (AUCadj) of 0.914 (P < 0.001) for EC detection. The combination of 2-oleoylglycerol and TAG42:2-FA12:0 allowed the distinction of R cases from NR cases with an AUCadj of 0.901 (P < 0.001). Type I R cases were also characterized by much lower levels of bile acids and elevated concentrations of phosphorylated fibrinogen cleavage peptide, whereas type II R cases displayed higher levels of ceramides. The findings from our pilot study provide a detailed metabolomics study of EC and identify putative serum biomarkers for defining clinically relevant risk groups. PMID- 29593654 TI - Ethnic Disparities in Endothelial Function and Its Cardiometabolic Correlates: The Pathobiology of Prediabetes in A Biracial Cohort Study. AB - Background: Endothelial function (EF) reflects the balance between vasodilatory and vasoconstrictive factors produced by (or acting on) the innermost lining of blood vessels. Endothelial dysfunction, an imbalance between these factors that favors vasoconstriction, has been associated with increased risk for cardiovascular disease. However, the influence of race/ethnicity and glycemic status on association between EF and cardiovascular risk factors remain to be clarified. Subjects and methods: We assessed EF in relation to glycemia and cardiometabolic profile in African-American (AA) and European-American (EA) offspring of parents with type 2 diabetes (T2D), who are participants in the prospective pathobiology and reversibility of prediabetes in a biracial cohort (PROP-ABC) study. Assessments at enrollment included a 75 g oral glucose tolerance test (OGTT), blood pressure, anthropometry, body composition (DEXA), and lipid profile. Other assessments were insulin sensitivity and resting energy expenditure. EF was measured using flow-mediated vasodilation (EndoPAT 2000) and expressed as reactive hyperemia index (RHI). Results: We studied 190 subjects (100 AA, 90 C), mean age (+/-SD) 53.1 +/- 9.1 years, and body mass index 30.6 +/- 6.8 kg/m2. Based on OGTT data, 96 subjects (52 AA, 44 EA) had prediabetes and 94 subjects were normoglycemic (48 AA and 46 EA). The RHI was lower in AA than EA (2.17 +/- 0.55 vs. 2.36 +/- 0.72, P = 0.05) and in prediabetic than normoglycemic subjects (2.14 +/- 0.62 vs. 2.38 +/- 0.65, P = 0.013). Using RHI <= 1.68 as diagnostic cut-off, 19% of participants with prediabetes and 10% of normoglycemic participants had endothelial dysfunction (P = 0.04). In univariate models, RHI was positively associated with age and HDL cholesterol levels, and inversely associated with adiposity, diastolic blood pressure, and 2hr plasma glucose. The association between RHI and adiposity was stronger in men than women. The association between RHI and age, glucose and HDL cholesterol displayed marked ethnic disparities. Conclusion: In our biracial cohort comprising offspring of parents with T2D, prediabetes increased the risk of endothelial dysfunction. However, the association between EF and cardiometabolic risk factors was significantly modified by ethnicity and gender. Our findings support current understanding of endothelial dysfunction as an early sensitive indicator of cardiometabolic risk. PMID- 29593655 TI - Pattern of Use of Biosimilar and Originator Somatropin in Italy: A Population Based Multiple Databases Study During the Years 2009-2014. AB - Purpose: Somatropin [recombinant growth hormone (rGH)] is approved in children and adults for several conditions involving growth disturbances and the corresponding biosimilar is available in Italy since 2006. No population-based data are available on the pattern of rGH use in Italian clinical practice. This study aimed at exploring the pattern of biosimilar and originator rGH use in six Italian centers, where different policy interventions promoted biosimilar use. Methods: This population-based, drug-utilization study was conducted in the years 2009-2014, using administrative databases of Umbria, Tuscany, and Lazio Regions and Local Health Units of Caserta, Treviso, and Palermo. Naive rGH users were characterized, and prevalence of use and discontinuation were assessed over time. Results: Among 6,785 patients treated with rGH during the study years, 4,493 (66.2%) were naive users (males/females = 1.3), mostly affected by GH deficiency. The prevalence of rGH use increased from 2009 to 2010, remaining stable thereafter, but it was heterogeneous across centers (twofold higher prevalence of use in center n.2 than centers n.4 and 1 in 2014). Biosimilar rGH uptake increased over time but was low (7.8% in 2014) and heterogeneous as well. Discontinuation of rGH therapy occurred in 54.0% of naive users, more frequently in females than males (58.1 vs. 50.9%). During the first year of treatment, discontinuation was frequent (39.9%), but no statistically significant differences were observed in treatment persistence for biosimilar vs. originator rGH (p > 0.05). Conclusion: Geographical heterogeneity in the prevalence of rGH use was observed. Similarly, the biosimilar rGH uptake was low and variable across centers. Post-marketing monitoring is required to continuously monitor the benefit-risk profile of rGH, thus guaranteeing greater savings than only promoting lowest cost rGH. PMID- 29593656 TI - Serum Phthalate and Triclosan Levels Have Opposing Associations With Risk Factors for Gestational Diabetes Mellitus. AB - Certain phthalates and bisphenol A (BPA) have been associated with insulin resistance and type 2 diabetes in non-pregnant adults, but studies of gestational diabetes mellitus (GDM) have reported conflicting results for phthalates and no associations with BPA. Our aim was to investigate the relationship between maternal serum levels of phthalate metabolites and phenols at 10-17 weeks of gestation and glucose homeostasis at 28 weeks of gestation. 232 women aged >=16 years without type 1 or 2 diabetes with singleton male pregnancies were recruited from a single UK maternity centre between 2001 and 2009 as part of a prospective observational study (Cambridge Baby Growth Study). Serum levels of 16 phthalate metabolites and 9 phenols (including BPA) were measured using liquid chromatography/tandem mass spectrometry. Oral glucose tolerance tests were performed at 28 weeks. 47/232 (20.3%) women had GDM. First-trimester triclosan (TCS) was inversely associated with incident GDM (adjusted odds ratio per log increase in concentration 0.54, 95% confidence interval 0.34-0.86, p = 0.010). Amongst women without GDM, first-trimester mono-(2-ethylhexyl) phthalate and mono(carboxyisooctyl) phthalate levels were positively associated with 120-min plasma glucose (adjusted beta 0.268 and 0.183, p = 0.0002 and 0.010, respectively) in mid-pregnancy. No other monotonic associations were detected between phthalate or phenol levels and fasting or stimulated plasma glucose, beta cell function, insulin resistance, or 60-min disposition index. Our results support a glycaemia-raising effect of phthalates during pregnancy, consistent with findings in non-pregnant populations and suggest a possible protective effect of exposure to TCS against GDM. PMID- 29593657 TI - Lipoprotein Lipase Expression in Hypothalamus Is Involved in the Central Regulation of Thermogenesis and the Response to Cold Exposure. AB - Lipoprotein lipase (LPL) is expressed in different areas of the brain, including the hypothalamus and plays an important role in neural control of the energy balance, including feeding behavior and metabolic fluxes. This study tested the hypothesis that hypothalamic LPL participates in the control of body temperature. We first showed that cold exposure induces decreased activity and expression of LPL in the mouse hypothalamus. We then selectively deleted LPL in the mediobasal hypothalamus (MBH) through an adeno-associated virus approach in LPL-floxed mice and generated MBHDelta Lpl mice with 30-35% decrease in hypothalamic LPL activity. Results showed a decrease in body temperature in MBHDelta Lpl mice when compared with controls at 22 degrees C. Exposure to cold (4 degrees C for 4 h) decreased the body temperature of the control mice while that of the MBHDelta Lpl mice remained similar to that observed at 22 degrees C. MBHDelta Lpl mice also showed increased energy expenditure during cold exposure, when compared to controls. Finally, the selective MBH deletion of LPL also increased the expression of the thermogenic PRMD16 and Dio2 in subcutaneous and perigonadal adipose tissues. Thus, the MBH LPL deletion seems to favor thermogenesis. These data demonstrate that for the first time hypothalamic LPL appears to function as a regulator of body temperature and cold-induced thermogenesis. PMID- 29593658 TI - Economic Evaluation of PRIMROSE-A Trial-Based Analysis of an Early Childhood Intervention to Prevent Obesity. AB - Background: Childhood obesity is a major clinical and economic health concern. Alongside the clinical understanding of obesity, there is a growing interest in designing and implementing interventions that are worth their money given the scarce resources in the health care sector. This study is one of the first efforts to provide evidence by assessing the effects and costs of a population based primary prevention intervention targeting pre-school children attending child health centers in Sweden. Methods: The economic evaluation is based on the PRIMROSE cluster-randomized controlled trial aiming to establish healthy eating and physical activity among pre-school children (9-48 months of age) through motivational interviewing applied by trained nurses at child health centers. The cost-effectiveness is assessed over the trial period from a societal perspective. The primary outcome was BMI at age 4. Cost data was prospectively collected alongside the trial. Scenario analyses were carried out to identify uncertainty. Results: The estimated additional mean total costs of the PRIMROSE intervention were 342 Euro (95% CI: 334; 348) per child. During pre-school years direct costs mainly consist of training costs and costs for the additional time used by nurses to implement the intervention compared to usual care. Early indirect costs mainly consist of parents' absence from work due to their participation in the intervention. The incremental cost-effectiveness ratio in the base case analysis was 3,109 Euro per 1 BMI unit prevented. Conclusion: We cannot provide evidence that the PRIMROSE intervention is cost-effective, given the uncertainty in the effect measure. Until further evidence is provided, we recommend resources to be spent elsewhere within the field of obesity prevention. Furthermore, to achieve valid and reliable cost-effectiveness results, the economic evaluation of obesity prevention programs in early childhood should incorporate the life time impact to capture all relevant costs and benefits.

AB - Objective: To elucidate whether the genetic platforms of blaCTX-M contribute to the phenotypes of multi-drug-resistance (MDR) in the first carbapenemase producing K. pneumoniae strains isolated in Chile. Method: Twenty-two carbapenemase-producing K. pneumoniae strains isolated from different Chilean patients and hospitals were studied. Their genetic relatedness was assessed by PFGE and MLST. The levels of antibiotic resistance were evaluated by determining the minimum inhibitory concentration of various antimicrobials. In addition, several antibiotic resistance genes of clinical relevance in Chile were investigated. The prevalence, allelic variants, and genetic platforms of blaCTX-M were determined by PCR and sequencing. Results: Out of the 22 strains studied, 20 carry KPC, one carries NDM-1, and one carries OXA-370. The PFGE analysis showed three clades with a genetic relatedness >85%, two formed by four strains and one by eight strains. The other strains are not genetically related, and a total of 17 different pulse types were detected. Ten different STs were identified, the main ones being ST258 (five strains) and ST1161 (seven strains). The isolates presented different percentages of resistance, and 82% were resistant to all the beta-lactams tested, 91% to ciprofloxacin, 73% to colistin, 59% to gentamicin, 50% to amikacin, and only 9% to tigecycline. All isolates carried blaTEM and blaSHV, whereas 71% carried aac(6')Ib-cr, and 57% one qnr gene (A, B, C, D, or S). The blaCTX-M gene was found in 10 of the isolates (4 blaCTX-M-15 and 6 blaCTX M-2). The characterization of the platform, in seven selected strains, revealed that the gene is associated with unusual class 1 integrons and insertion sequences such as ISCR1, ISECp1, and IS26. Conclusion: In the first carbapenemase producing K. pneumoniae strains isolated in Chile the genetic platform of blaCTX M-2 corresponds to an unusual class 1 integron that can be responsible for the MDR phenotype, whereas the genetic platforms of blaCTX-M-15 are associated with different IS and do not contribute to multi-drug resistance. PMID- 29593659 TI - How to Control HTLV-1-Associated Diseases: Preventing de Novo Cellular Infection Using Antiviral Therapy. AB - Five to ten million individuals are infected by Human T-cell Leukemia Virus type 1 (HTLV-1). HTLV-1 is transmitted through prolonged breast-feeding, by sexual contacts and by transmission of infected T lymphocytes through blood transfusion. One to ten percent of infected carriers will develop a severe HTLV-1-associated disease: Adult-T-cell leukemia/lymphoma (ATLL), or a neurological disorder named Tropical Spastic Paraparesis/HTLV-1 Associated Myelopathy (TSP/HAM). In vivo, HTLV-1 is mostly detected in CD4+ T-cells, and to a lesser extent in CD8+ T cells and dendritic cells. There is a strong correlation between HTLV-1 proviral load (PVL) and clinical status of infected individuals. Thus, reducing PVL could be part of a strategy to prevent or treat HTLV-1-associated diseases among carriers. Treatment of ATLL patients using conventional chemotherapy has very limited benefit. Some chronic and acute ATLL patients are, however, efficiently treated with a combination of interferon alpha and zidovudine (IFN-alpha/AZT), to which arsenic trioxide is added in some cases. On the other hand, no efficient treatment for TSP/HAM patients has been described yet. It is therefore crucial to develop therapies that could either prevent the occurrence of HTLV-1-associated diseases or at least block the evolution of the disease in the early stages. In vivo, reverse transcriptase (RT) activity is low in infected cells, which is correlated with a clonal mode of viral replication. This renders infected cells resistant to nucleoside RT inhibitors such as AZT. However, histone deacetylase inhibitors (HDACi) associated to AZT efficiently induces viral expression and prevent de novo cellular infection. In asymptomatic STLV-1 infected non-human primates, HDACi/AZT combination allows a strong decrease in the PVL. Unfortunately, rebound in the PVL occurs when the treatment is stopped, highlighting the need for better antiviral compounds. Here, we review previously used strategies targeting HTLV-1 replication. We also tested a series of HIV-1 RT inhibitors in an in vitro anti-HTLV-1 screen, and report that bis-POM-PMEA (adefovir dipivoxil) and bis-POC-PMPA (tenofovir disoproxil) are much more efficient compared to AZT to decrease HTLV-1 cell-to-cell transmission in vitro. Our results suggest that revisiting already established antiviral drugs is an interesting approach to discover new anti-HTLV-1 drugs.

AB - Francisella (F.) tularensis is a highly virulent, Gram-negative bacterial pathogen and the causative agent of the zoonotic disease tularemia. Here, we generated, analyzed and characterized a high quality circular genome sequence of the F. tularensis subsp. holarctica strain 12T0050 that caused fatal tularemia in a hare. Besides the genomic structure, we focused on the analysis of oriC, unique to the Francisella genus and regulating replication in and outside hosts and the first report on genomic DNA methylation of a Francisella strain. The high quality genome was used to establish and evaluate a diagnostic whole genome sequencing pipeline. A genotyping strategy for F. tularensis was developed using various bioinformatics tools for genotyping. Additionally, whole genome sequences of F. tularensis subsp. holarctica isolates isolated in the years 2008-2015 in Germany were generated. A phylogenetic analysis allowed to determine the genetic relatedness of these isolates and confirmed the highly conserved nature of F. tularensis subsp. holarctica.

AB - Exoelectrogenic biofilms capable of extracellular electron transfer are important in advanced technologies such as those used in microbial electrochemical remediation systems (MERS) Few bacterial strains have been, nevertheless, obtained from MERS exoelectrogenic biofilms and characterized for bioremediation potential. Here we report the identification of one such bacterial strain, Citrobacter sp. KVM11, a petrophilic, iron reducing bacterial strain isolated from hydrocarbon fed MERS, producing anodic currents in microbial electrochemical systems. Fe(III) reduction of 90.01 +/- 0.43% was observed during 5 weeks of incubation with Fe(III) supplemented liquid cultures. Biodegradation screening assays showed that the hydrocarbon degradation had been carried out by metabolically active cells accompanied by growth. The characteristic feature of diazo dye decolorization was used as a simple criterion for evaluating the electrochemical activity in the candidate microbe. The electrochemical activities of the strain KVM11 were characterized in a single chamber fuel cell and three electrode electrochemical cells. The inoculation of strain KVM11 amended with acetate and citrate as the sole carbon and energy sources has resulted in an increase in anodic currents (maximum current density) of 212 +/- 3 and 359 +/- mA/m2 with respective coulombic efficiencies of 19.5 and 34.9% in a single chamber fuel cells. Cyclic voltammetry studies showed that anaerobically grown cells of strain KVM11 are electrochemically active whereas aerobically grown cells lacked the electrochemical activity. Electrobioremediation potential of the strain KVM11 was investigated in hydrocarbonoclastic and dye detoxification conditions using MERS. About 89.60% of 400 mg l-1 azo dye was removed during the first 24 h of operation and it reached below detection limits by the end of the batch operation (60 h). Current generation and biodegradation capabilities of strain KVM11 were examined using an initial concentration of 800 mg l-1 of diesel range hydrocarbons (C9-C36) in MERS (maximum currentdensity 50.64 +/- 7 mA/m2; power density 4.08 +/- 2 mW/m2, 1000 omega, hydrocarbon removal 60.14 +/- 0.7%). Such observations reveal the potential of electroactive biofilms in the simultaneous remediation of hydrocarbon contaminated environments with generation of energy.

AB - Actinomycetes have been extensively exploited as one of the most prolific secondary metabolite-producer sources and continue to be in the focus of interest in the constant search of novel bioactive compounds. The availability of less expensive next generation genome sequencing techniques has not only confirmed the extraordinary richness and broad distribution of silent natural product biosynthetic gene clusters among these bacterial genomes, but also has allowed the incorporation of genomics in bacterial taxonomy and systematics. As part of our efforts to isolate novel strains from unique environments, we explored lichen associated microbial communities as unique assemblages to be studied as potential sources of novel bioactive natural products with application in biotechnology and drug discovery. In this work, we have studied the whole genome sequences of two new Amycolatopsis strains (CA-126428 and CA-128772) isolated from tropical lichens, and performed a comparative genomic analysis with 41 publicly available Amycolatopsis genomes. This work has not only permitted to infer and discuss their taxonomic position on the basis of the different phylogenetic approaches used, but has also allowed to assess the richness and uniqueness of the biosynthetic pathways associated to primary and secondary metabolism, and to provide a first insight on the potential role of these bacteria in the lichen associated microbial community. PMID- 29593665 TI - Impact of Branched-Chain Amino Acid Catabolism on Fatty Acid and Alkene Biosynthesis in Micrococcus luteus. AB - Micrococcus luteus naturally produces alkenes, unsaturated aliphatic hydrocarbons, and represents a promising host to produce hydrocarbons as constituents of biofuels and lubricants. In this work, we identify the genes for key enzymes of the branched-chain amino acid catabolism in M. luteus, whose first metabolic steps lead also to the formation of primer molecules for branched-chain fatty acid and olefin biosynthesis, and demonstrate how these genes can be used to manipulate the production of specific olefins in this organism. We constructed mutants of several gene candidates involved in the branched-chain amino acid metabolism or its regulation and investigated the resulting changes in the cellular fatty acid and olefin profiles by GC/MS. The gene cluster encoding the components of the branched-chain alpha-keto acid dehydrogenase (BCKD) complex was identified by deletion and promoter exchange mutagenesis. Overexpression of the BCKD gene cluster resulted in about threefold increased olefin production whereas deletion of the cluster led to a drastic reduction in branched-chain fatty acid content and a complete loss of olefin production. The specificities of the acyl CoA dehydrogenases of the branched amino acid degradation pathways were deduced from the fatty acid and olefin profiles of the respective deletion mutant strains. In addition, growth experiments with branched amino acids as the only nitrogen source were carried out with the mutants in order to confirm our annotations. Both the deletion mutant of the BCKD complex, responsible for the further degradation of all three branched-chain amino acids, as well as the deletion mutant of the proposed isovaleryl-CoA dehydrogenase (specific for leucine degradation) were not able to grow on leucine in contrast to the parental strain. In conclusion, our experiments allow the unambigous assignment of specific functions to the genes for key enzymes of the branched-chain amino acid metabolism of M. luteus. We also show how this knowledge can be used to engineer the isomeric composition and the chain lengths of the olefins produced by this organism. PMID- 29593666 TI - Factors Involved in the Persistence of a Shiga Toxin-Producing Escherichia coli O157:H7 Strain in Bovine Feces and Gastro-Intestinal Content. AB - Healthy cattle are the primary reservoir for O157:H7 Shiga toxin-producing E. coli responsible for human food-borne infections. Because farm environment acts as a source of cattle contamination, it is important to better understand the factors controlling the persistence of E. coli O157:H7 outside the bovine gut. The E. coli O157:H7 strain MC2, identified as a persistent strain in French farms, possessed the characteristics required to cause human infections and genetic markers associated with clinical O157:H7 isolates. Therefore, the capacity of E. coli MC2 to survive during its transit through the bovine gastro intestinal tract (GIT) and to respond to stresses potentially encountered in extra-intestinal environments was analyzed. E. coli MC2 survived in rumen fluids, grew in the content of posterior digestive compartments and survived in bovine feces at 15 degrees C predicting a successful transit of the bacteria along the bovine GIT and its persistence outside the bovine intestine. E. coli MC2 possessed the genetic information encoding 14 adherence systems including adhesins with properties related to colonization of the bovine intestine (F9 fimbriae, EhaA and EspP autotransporters, HCP pilus, FdeC adhesin) reflecting the capacity of the bacteria to colonize different segments of the bovine GIT. E. coli MC2 was also a strong biofilm producer when incubated in fecal samples at low temperature and had a greater ability to form biofilms than the bovine commensal E. coli strain BG1. Furthermore, in contrast to BG1, E. coli MC2 responded to temperature stresses by inducing the genes cspA and htrA during its survival in bovine feces at 15 degrees C. E. coli MC2 also activated genes that are part of the GhoT/GhoS, HicA/HicB and EcnB/EcnA toxin/antitoxin systems involved in the response of E. coli to nutrient starvation and chemical stresses. In summary, the large number of colonization factors known to bind to intestinal epithelium and to biotic or abiotic surfaces, the capacity to produce biofilms and to activate stress fitness genes in bovine feces could explain the persistence of E. coli MC2 in the farm environment. PMID- 29593667 TI - Amplicon Sequencing Reveals Microbiological Signatures in Spent Nuclear Fuel Storage Basins. AB - Water quality is an important determinant for the structural integrity of alloy cladded fuels and assemblies during long-term wet storage. Detailed characterization of a water filled storage basin for spent nuclear reactor fuel was performed following the formation and proliferation of an amorphous white flocculent. White precipitant was sampled throughout the storage basin for chemical and spectroscopic characterization, and environmental DNA was extracted for 454 pyrosequencing of bacterial 16S rRNA gene diversity. Accordingly, spectroscopic analyses indicated the precipitant to be primarily amorphous to crystalline aluminum (oxy) hydroxides with minor associated elemental components including Fe, Si, Ti, and U. High levels of organic carbon were co-localized with the precipitant relative to bulk dissolved organic concentrations. Bacterial densities were highly variable between sampling locations and with depth within the water filled storage basin; cell numbers ranged from 4 * 103to 4 * 104 cells/mL. Bacterial diversity that was physically associated with the aluminum (oxy) hydroxide complexes exceeded an estimated 4,000 OTUs/amplicon library (3% cutoff) and the majority of sequences were aligned to the families Burkholderiaceae (23%), Nitrospiraceae (23%), Hyphomicrobiaceae (17%), and Comamonadaceae (6%). We surmise that episodic changes in the physical and chemical properties of the basin contribute to the polymerization of aluminum (oxy) hydroxides, which in turn can chemisorb nutrients, carbon ligands and bacterial cells from the surrounding bulk aqueous phase. As such, these precipitants should establish favorable microhabitats for bacterial colonization and growth. Comparative analyses of 16S rRNA gene amplicon libraries across a selection of natural and engineered aquatic ecosystems were performed and microbial community and taxonomic signatures unique to the spent nuclear fuel (SNF) storage basin environment were revealed. These insights could spur the development of tractable bio-indicators that are specific of and diagnostic for water quality at discrete locations and finer scales of resolution, marking an important contribution for improved water quality and management of SNF storage facilities. PMID- 29593668 TI - Simulation Study of cDNA Dataset to Investigate Possible Association of Differentially Expressed Genes of Human THP1-Monocytic Cells in Cancer Progression Affected by Bacterial Shiga Toxins. AB - Shiga toxin (Stxs) is a family of structurally and functionally related bacterial cytotoxins produced by Shigella dysenteriae serotype 1 and shigatoxigenic group of Escherichia coli that cause shigellosis and hemorrhagic colitis, respectively. Until recently, it has been thought that Stxs only inhibits the protein synthesis and induces expression to a limited number of genes in host cells, but recent data showed that Stxs can trigger several signaling pathways in mammalian cells and activate cell cycle and apoptosis. To explore the changes in gene expression induced by Stxs that have been shown in other systems to correlate with cancer progression, we performed the simulated analysis of cDNA dataset and found differentially expressed genes (DEGs) of human THP1-monocytic cells treated with Stxs. In this study, the entire data (treated and untreated replicates) was analyzed by statistical algorithms implemented in Bioconductor packages. The output data was validated by the k-fold cross technique using generalized linear Gaussian models. A total of 50 DEGs were identified. 7 genes including TSLP, IL6, GBP1, CD274, TNFSF13B, OASL, and PNPLA3 were considerably (<0.00005) related to cancer proliferation. The functional enrichment analysis showed 6 down-regulated and 1 up-regulated genes. Among these DEGs, IL6 was associated with several cancers, especially with leukemia, lymphoma, lungs, liver and breast cancers. The predicted regulatory motifs of these genes include conserved RELA, STATI, IRFI, NF-kappaB, PEND, HLF, REL, CEBPA, DI_2, and NFKB1 transcription factor binding sites (TFBS) involved in the complex biological functions. Thus, our findings suggest that Stxs has the potential as a valuable tool for better understanding of treatment strategies for several cancers. PMID- 29593669 TI - Assessment of Fecal Indicator Bacteria and Potential Pathogen Co-Occurrence at a Shellfish Growing Area. AB - Routine monitoring of shellfish growing waters for bacteria indicative of human sewage pollution reveals little about the bacterial communities that co-occur with these indicators. This study investigated the bacterial community, potential pathogens, and fecal indicator bacteria in 40 water samples from a shellfish growing area in the Chesapeake Bay, USA. Bacterial community composition was quantified with deep sequencing of 16S rRNA gene amplicons, and absolute gene abundances were estimated with an internal standard (Thermus thermophilus genomes). Fecal coliforms were quantified by culture, and Vibrio vulnificus and V. parahaemolyticus with quantitative PCR. Fecal coliforms and V. vulnificus were detected in most samples, and a diverse assemblage of potential human pathogens were detected in all samples. These taxa followed two general patterns of abundance. Fecal coliforms and 16S rRNA genes for Enterobacteriaceae, Aeromonas, Arcobacter, Staphylococcus, and Bacteroides increased in abundance after a 1.3 inch rain event in May, and, for some taxa, after smaller rain events later in the season, suggesting that these are allochthonous organisms washed in from land. Clostridiaceae and Mycobacterium 16S rRNA gene abundances increased with day of the year and were not positively related to rainfall, suggesting that these are autochthonous organisms. Other groups followed both patterns, such as Legionella. Fecal coliform abundance did not correlate with most other taxa, but were extremely high following the large rainstorm in May when they co-occurred with a broad range of potential pathogen groups. V. vulnificus were absent during the large rainstorm, and did not correlate with 16S rRNA abundances of Vibrio spp. or most other taxa. These results highlight the complex nature of bacterial communities and the limited utility of using specific bacterial groups as indicators of pathogen presence. PMID- 29593670 TI - Porcine Circovirus-Like Virus P1 Inhibits Wnt Signaling Pathway in Vivo and in Vitro. AB - Porcine circovirus-like virus P1 is an important pathogen of the current pig industry, the infection mechanism is not entirely clear. Wnt signaling pathway plays an important role in the growth of young animals and infection of some viruses. This study was designed to demonstrate the effects of P1 infection on the Wnt signaling pathway. In vivo experiments, we demonstrated the down regulatory effects of P1 infection in piglets and mice on the downstream components expression levels of Wnt signaling pathway, and the effects of Wnt signaling pathway activation on the pathogenesis of P1. In vitro studies, we found P1 infection down-regulated protein level of beta-catenin and mRNA level of mmp2, prevented the beta-catenin from entering into nucleus, abolished the TCF/LEF promoter activity, proved that P1 could inhibit the activation of Wnt signaling pathway in vitro. Finally, we found that VP1 of P1 virus also had the inhibitory effects on Wnt signaling pathway in vitro, elucidated the mechanism of P1's inhibitory effects on the Wnt signaling pathway and offered the possibility that the suppression of Wnt signaling pathway was involved in the post-weaning multisystemic wasting syndrome (PMWS), laying a foundation for elucidating the pathogenesis of P1. PMID- 29593671 TI - The Hemagglutinin-Neuraminidase (HN) Head Domain and the Fusion (F) Protein Stalk Domain of the Parainfluenza Viruses Affect the Specificity of the HN-F Interaction. AB - Membrane fusion by the parainfluenza viruses is induced by virus-specific functional interaction between the attachment protein (HN) and the fusion (F) protein. This interaction is thought to be mediated by transient contacts between particular amino acids in the HN stalk domain and those in the F head domain. However, we recently reported that replacement of specified amino acids at or around the dimer interface of the HN head domain remarkably affected the F protein specificity. We then intended to further investigate this issue in the present study and revealed that the HPIV2 HN protein can be converted to an SV41 HN-like protein by substituting at least nine amino acids in the HPIV2 HN head domain with the SV41 HN counterparts in addition to the replacement of the stalk domain, indicating that specified amino acids in the HN head domain play very important roles in determining the specificity of the HN-F interaction. On the other hand, we previously reported that the PIV5 F protein can be converted to an SV41 F-like protein by replacing 21 amino acids in the head domain of the PIV5 F protein with those of the SV41 F protein. We then intended to further investigate this issue in the present study and found that replacement of 15 amino acids in the stalk domain in addition to the replacement of the 21 amino acids in the head domain of the PIV5 F protein resulted in creation of a more SV41 F-like protein, indicating that specified amino acids in the F stalk domain play important roles in determining the specificity of the HN-F interaction. These results suggest that the conformations of the HN stalk domain and the F head domain are dependent on the structures of the HN head domain and the F stalk domain, respectively. Presumably, the conformations of the former domains, which are considered directly involved in the HN-F interaction, can be modified by subtle changes in the structure of the latter domains, resulting in an altered specificity for the interacting partners. PMID- 29593672 TI - Signals Involved in Regulation of Hepatitis C Virus RNA Genome Translation and Replication. AB - Hepatitis C virus (HCV) preferentially replicates in the human liver and frequently causes chronic infection, often leading to cirrhosis and liver cancer. HCV is an enveloped virus classified in the genus Hepacivirus in the family Flaviviridae and has a single-stranded RNA genome of positive orientation. The HCV RNA genome is translated and replicated in the cytoplasm. Translation is controlled by the Internal Ribosome Entry Site (IRES) in the 5' untranslated region (5' UTR), while also downstream elements like the cis-replication element (CRE) in the coding region and the 3' UTR are involved in translation regulation. The cis-elements controlling replication of the viral RNA genome are located mainly in the 5'- and 3'-UTRs at the genome ends but also in the protein coding region, and in part these signals overlap with the signals controlling RNA translation. Many long-range RNA-RNA interactions (LRIs) are predicted between different regions of the HCV RNA genome, and several such LRIs are actually involved in HCV translation and replication regulation. A number of RNA cis elements recruit cellular RNA-binding proteins that are involved in the regulation of HCV translation and replication. In addition, the liver-specific microRNA-122 (miR-122) binds to two target sites at the 5' end of the viral RNA genome as well as to at least three additional target sites in the coding region and the 3' UTR. It is involved in the regulation of HCV RNA stability, translation and replication, thereby largely contributing to the hepatotropism of HCV. However, we are still far from completely understanding all interactions that regulate HCV RNA genome translation, stability, replication and encapsidation. In particular, many conclusions on the function of cis-elements in HCV replication have been obtained using full-length HCV genomes or near-full length replicon systems. These include both genome ends, making it difficult to decide if a cis-element in question acts on HCV replication when physically present in the plus strand genome or in the minus strand antigenome. Therefore, it may be required to use reduced systems that selectively focus on the analysis of HCV minus strand initiation and/or plus strand initiation. PMID- 29593674 TI - Metabolic Adaptation of Methanogens in Anaerobic Digesters Upon Trace Element Limitation. AB - Anaerobic digestion (AD) is a complex multi-stage process relying on the activity of highly diverse microbial communities including hydrolytic, acidogenic and syntrophic acetogenic bacteria as well as methanogenic archaea. The lower diversity of methanogenic archaea compared to the bacterial groups involved in AD and the corresponding lack of functional redundancy cause a stronger susceptibility of methanogenesis to unfavorable process conditions such as trace element (TE) deprivation, thus controlling the stability of the overall process. Here, we investigated the effects of a slowly increasing TE deficit on the methanogenic community function in a semi-continuous biogas process. The aim of the study was to understand how methanogens in digester communities cope with TE limitation and sustain their growth and metabolic activity. Two lab-scale biogas reactors fed with distillers grains and supplemented with TEs were operated in parallel for 76 weeks before one of the reactors was subjected to TE deprivation, leading to a decline of cobalt and molybdenum concentrations from 0.9 to 0.2 mg/L, nickel concentrations from 2.9 to 0.8 mg/L, manganese concentrations from 38 to 18 mg/L, and tungsten concentrations from 1.4 to 0.2 mg/L. Amplicon sequencing of mcrA genes revealed Methanosarcina (72%) and Methanoculleus (23%) as the predominant methanogens in the undisturbed reactors. With increasing TE limitation, the relative abundance of Methanosarcina dropped to 67% and a slight decrease of acetoclastic methanogenic activity was observed in batch tests with 13C-methyl-labeled acetate, suggesting a shift toward syntrophic acetate oxidation coupled to hydrogenotrophic methanogenesis. Metaproteome analysis revealed abundance shifts of the enzymes involved in methanogenic pathways. Proteins involved in methylotrophic and acetoclastic methanogenesis decreased in abundance while formylmethanofuran dehydrogenase from Methanosarcinaceae increased, confirming our hypothesis of a shift from acetoclastic to hydrogenotrophic methanogenesis by Methanosarcina. Both Methanosarcina and Methanoculleus increased the abundance of N5-methyltetrahydromethanopterin coenzyme M methyltransferase and methyl-coenzyme M reductase. However, these efforts to preserve the ion motive force for energy conservation were seemingly more successful in Methanoculleus. We conclude that both methanogenic genera use different strategies to stabilize their energy balance under TE limitation. Methanosarcina switched from TE expensive pathways (methylotrophic and acetoclastic methanogenesis) to hydrogenotrophic methanogenesis. Methanoculleus showed a higher robustness and was favored over the more fastidious Methanosarcina, thus stabilizing reactor performance under TE limitation. PMID- 29593675 TI - Cryptococcal Antigen Screening in Asymptomatic HIV-Infected Antiretroviral Naive Patients in Cameroon and Evaluation of the New Semi-Quantitative Biosynex CryptoPS Test. AB - Background: Cryptococcal meningitis (CM) is a major cause of AIDS-related mortality in Africa. Detection of serum cryptococcal antigen (CrAg) predicts development of CM in antiretroviral (ART) naive HIV-infected patients with severe immune depression. Systematic pre-ART CrAg screening and pre-emptive oral fluconazole is thus recommended. We postulated that a semi-quantitative CrAg screening approach could offer clinically relevant advantages. Methods: ART-naive asymptomatic adult outpatients with <100 CD4 cells/mm3 presenting to the Yaounde Central Hospital, Cameroon were screened for CrAg using the IMMY lateral flow assay (LFA). CrAg positive patients were consented for lumbar puncture and those with proven CM were treated with combination antifungal therapy and those with no CM were offered long-term oral fluconazole. Simultaneous on-site evaluation of CrAg detection using the new LFA Biosynex(r) CryptoPS test was performed and both tests were subsequently compared to a reference commercialized CrAg enzyme immunoassay (EIA). Results: Prevalence of serum CrAg in 186 screened adults was 7.5% (95%CI: 4.5-12.4). In CrAg positive patients, CM prevalence was 45.5% (95%CI: 18.3-75.7). IMMY and Biosynex CryptoPS strongly agreed in serum, plasma, and cerebrospinal fluid (Kappa: 98.4, 99.5, 100%, respectively, p < 0.001), and disagreed in urine (29 isolated positive CrAg in urine with IMMY, none with Biosynex and none of whom had proven CM). Compared to EIA, serum specificities were 96.6 and 98.3%, respectively. With Biosynex CryptoPS, all CM patients were serum T2-band positive compared to nonewithout CM. Median EIA reciprocal titre was 160 (IQR: 13.5-718.8) and titres >160 strongly correlated with proven CM and Biosynex CryptoPS T2-band positivity. During the 1-year follow up period, there was no incident case of CM among screened patients and overall incidence of all cause mortality was 31.5 per 100 person-years-at-risk (95%CI: 23.0-43.1). Conclusion: HIV-associated asymptomatic cryptococcosis is common in Cameroon, warranting integrated systematic screening and treatment. Biosynex CryptoPS holds promise, at point of care, for rapidly stratifying CrAg positive patients for optimal management including lumbar puncture and combination antifungal therapy when needed. Summary findings: Prevalence of CrAg and meningitis (CM) is high in Cameroon. Biosynex CryptoPS is comparable to IMMY LFA in CrAg screening. Its T2 band correlates with high antigen titres and CM, thus promising for identifying patients requiring effective induction therapy. Note: This study was presented in part at the 10th International Conference on Cryptococcus and Cryptococcosis (ICCC) in Iguazu in Brazil from 26 to 30th March 2017 and won a prize oral presentation. PMID- 29593673 TI - Flavin-Based Electron Bifurcation, Ferredoxin, Flavodoxin, and Anaerobic Respiration With Protons (Ech) or NAD+ (Rnf) as Electron Acceptors: A Historical Review. AB - Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more positive reduction potential than that of the electron pair. Via this mechanism microorganisms generate low- potential electrons for the reduction of ferredoxins (Fd) and flavodoxins (Fld). The first example was described in 2008 when it was found that the butyryl-CoA dehydrogenase-electron-transferring flavoprotein complex (Bcd-EtfAB) of Clostridium kluyveri couples the endergonic reduction of ferredoxin (E0' = -420 mV) with NADH (-320 mV) to the exergonic reduction of crotonyl-CoA to butyryl-CoA (-10 mV) with NADH. The discovery was followed by the finding of an electron-bifurcating Fd- and NAD-dependent [FeFe] hydrogenase (HydABC) in Thermotoga maritima (2009), Fd-dependent transhydrogenase (NfnAB) in various bacteria and archaea (2010), Fd- and H2-dependent heterodisulfide reductase (MvhADG-HdrABC) in methanogenic archaea (2011), Fd- and NADH-dependent caffeyl-CoA reductase (CarCDE) in Acetobacterium woodii (2013), Fd and NAD-dependent formate dehydrogenase (HylABC-FdhF2) in Clostridium acidi urici (2013), Fd- and NADP-dependent [FeFe]-hydrogenase (HytA-E) in Clostridium autoethanogrenum (2013), Fd(?)- and NADH-dependent methylene-tetrahydrofolate reductase (MetFV-HdrABC-MvhD) in Moorella thermoacetica (2014), Fd- and NAD dependent lactate dehydrogenase (LctBCD) in A. woodii (2015), Fd- and F420H2 dependent heterodisulfide reductase (HdrA2B2C2) in Methanosarcina acetivorans (2017), and Fd- and NADH-dependent ubiquinol reductase (FixABCX) in Azotobacter vinelandii (2017). The electron-bifurcating flavoprotein complexes known to date fall into four groups that have evolved independently, namely those containing EtfAB (CarED, LctCB, FixBA) with bound FAD, a NuoF homolog (HydB, HytB, or HylB) harboring FMN, NfnB with bound FAD, or HdrA harboring FAD. All these flavoproteins are cytoplasmic except for the membrane-associated protein FixABCX. The organisms-in which they have been found-are strictly anaerobic microorganisms except for the aerobe A. vinelandii. The electron-bifurcating complexes are involved in a variety of processes such as butyric acid fermentation, methanogenesis, acetogenesis, anaerobic lactate oxidation, dissimilatory sulfate reduction, anaerobic- dearomatization, nitrogen fixation, and CO2 fixation. They contribute to energy conservation via the energy-converting ferredoxin: NAD+ reductase complex Rnf or the energy-converting ferredoxin-dependent hydrogenase complex Ech. This Review describes how this mechanism was discovered. PMID- 29593676 TI - Prospects of Nanostructure Materials and Their Composites as Antimicrobial Agents. AB - Nanostructured materials (NSMs) have increasingly been used as a substitute for antibiotics and additives in various products to impart microbicidal effect. In particular, use of silver nanoparticles (AgNPs) has garnered huge researchers' attention as potent bactericidal agent due to the inherent antimicrobial property of the silver metal. Moreover, other nanomaterials (carbon nanotubes, fullerenes, graphene, chitosan, etc.) have also been studied for their antimicrobial effects in order ensure their application in widespread domains. The present review exclusively emphasizes on materials that possess antimicrobial activity in nanoscale range and describes their various modes of antimicrobial action. It also entails broad classification of NSMs along with their application in various fields. For instance, use of AgNPs in consumer products, gold nanoparticles (AuNPs) in drug delivery. Likewise, use of zinc oxide nanoparticles (ZnO-NPs) and titanium dioxide nanoparticles (TiO2-NPs) as additives in consumer merchandises and nanoscale chitosan (NCH) in medical products and wastewater treatment. Furthermore, this review briefly discusses the current scenario of antimicrobial nanostructured materials (aNSMs), limitations of current research and their future prospects. To put various perceptive insights on the recent advancements of such antimicrobials, an extended table is incorporated, which describes effect of NSMs of different dimensions on test microorganisms along with their potential widespread applications. PMID- 29593677 TI - Close Link Between Harmful Cyanobacterial Dominance and Associated Bacterioplankton in a Tropical Eutrophic Reservoir. AB - Cyanobacteria tend to become the dominant phytoplankton component in eutrophic freshwater environments during warmer seasons. However, general observations of cyanobacterial adaptive advantages in these circumstances are insufficient to explain the prevalence of one species over another in a bloom period, which may be related to particular strategies and interactions with other components of the plankton community. In this study, we present an integrative view of a mixed cyanobacterial bloom occurring during a warm, rainy period in a tropical hydropower reservoir. We used high-throughput sequencing to follow temporal shifts in the dominance of cyanobacterial genera and shifts in the associated heterotrophic bacteria community. The bloom occurred during late spring-summer and included two distinct periods. The first period corresponded to Microcystis aeruginosa complex (MAC) dominance with a contribution from Dolichospermum circinale; this pattern coincided with high water retention time and low transparency. The second period corresponded to Cylindrospermopsis raciborskii and Synechococcus spp. dominance, and the reservoir presented lower water retention time and higher water transparency. The major bacterial phyla were primarily Cyanobacteria and Proteobacteria, followed by Actinobacteria, Bacteroidetes, Verrucomicrobia, and Planctomycetes. Temporal shifts in the dominance of cyanobacterial genera were not only associated with physical features of the water but also with shifts in the associated heterotrophic bacteria. The MAC bloom was associated with a high abundance of Bacteroidetes, particularly Cytophagales. In the second bloom period, Planctomycetes increased in relative abundance, five Planctomycetes OTUs were positively correlated with Synechococcus or C. raciborskii OTUs. Our results suggest specific interactions of the main cyanobacterial genera with certain groups of the heterotrophic bacterial community. Thus, considering biotic interactions may lead to a better understanding of the shifts in cyanobacterial dominance. PMID- 29593678 TI - Pangenomic Definition of Prokaryotic Species and the Phylogenetic Structure of Prochlorococcus spp. AB - The pangenome is the collection of all groups of orthologous genes (OGGs) from a set of genomes. We apply the pangenome analysis to propose a definition of prokaryotic species based on identification of lineage-specific gene sets. While being similar to the classical biological definition based on allele flow, it does not rely on DNA similarity levels and does not require analysis of homologous recombination. Hence this definition is relatively objective and independent of arbitrary thresholds. A systematic analysis of 110 accepted species with the largest numbers of sequenced strains yields results largely consistent with the existing nomenclature. However, it has revealed that abundant marine cyanobacteria Prochlorococcus marinus should be divided into two species. As a control we have confirmed the paraphyletic origin of Yersinia pseudotuberculosis (with embedded, monophyletic Y. pestis) and Burkholderia pseudomallei (with B. mallei). We also demonstrate that by our definition and in accordance with recent studies Escherichia coli and Shigella spp. are one species. PMID- 29593679 TI - Flavoring Production in Kamut(r), Quinoa and Wheat Doughs Fermented by Lactobacillus paracasei, Lactobacillus plantarum, and Lactobacillus brevis: A SPME-GC/MS Study. AB - This study identified the odor-active compounds and the qualitative characteristics of doughs from "ancient" grains flours fermented by lactic acid bacteria. For this purpose doughs made with quinoa and Kamut(r) flours have been produced and inoculated with strains belonging to the species Lactobacillus paracasei, Lactobacillus plantarum and Lactobacillus brevis and compared with fermented doughs made from 100% wheat flour. The quality of the doughs was determined by assessment of pH, total titratable acidity, lactic acid bacteria growth and flavor compounds. The results showed that lactic acid bacteria used were able to grow in the different substrates reaching more than 9.0 log CFU/g after 24 h fermentation, although the best microbial growth was recorded in the doughs made with quinoa flour fermented with Lactobacillus paracasei I1. Good acidification and heterogeneous aromatic profile were recognized in all the doughs even if the volatile composition mainly derived from microbial specie. Among all the used strains, mostly Lactobacillus paracasei I1 positively contributed to the aromatic profile of the doughs, independently from flour type, producing the highest amount of different ketones such as, diacetyl, acetoin, 2,6 dimethyl-4-heptanone, 5-methyl-3-hexanone, 4-methyl-3-penten-2-one, volatile compounds highly appreciated in the bakery products for their buttery, fatty and fruity notes. So, the positive characteristic of Lactobacillus paracasei I1 to enhance the production of desired volatile compounds could make it suitable as adjunct culture starter in the bakery industry. Many differences in volatile organic compounds derived also by the type of flour used. Quinoa fermented doughs were characterized for specific nutty, roasted, acid and buttery tones derived from pyrazines, ketones and acid compounds whereas Kamut(r) fermented doughs were characterized for fruity, rose, green and sweet tones derived from aldehydes and ketones production. So, the use of quinoa and Kamut(r) flours opportunely fermented, as partial or complete substitution of wheat flour, may be interesting for producing more balanced bakery products with respect to nutritional aspects and to unique aromatic profile. Furthermore, the supplementation of these flours, rich in protein content and free amino acids, could represent an optimal substrate to enhance the growth of lactic acid bacteria used as starter culture in leavened bakery products. PMID- 29593680 TI - Diversity and Contributions to Nitrogen Cycling and Carbon Fixation of Soil Salinity Shaped Microbial Communities in Tarim Basin. AB - Arid and semi-arid regions comprise nearly one-fifth of the earth's terrestrial surface. However, the diversities and functions of their soil microbial communities are not well understood, despite microbial ecological importance in driving biogeochemical cycling. Here, we analyzed the geochemistry and microbial communities of the desert soils from Tarim Basin, northwestern China. Our geochemical data indicated half of these soils are saline. Metagenomic analysis showed that bacterial phylotypes (89.72% on average) dominated the community, with relatively small proportions of Archaea (7.36%) and Eukaryota (2.21%). Proteobacteria, Firmicutes, Actinobacteria, and Euryarchaeota were most abundant based on metagenomic data, whereas genes attributed to Proteobacteria, Actinobacteria, Euryarchaeota, and Thaumarchaeota most actively transcribed. The most abundant phylotypes (Halobacterium, Halomonas, Burkholderia, Lactococcus, Clavibacter, Cellulomonas, Actinomycetospora, Beutenbergia, Pseudomonas, and Marinobacter) in each soil sample, based on metagenomic data, contributed marginally to the population of all microbial communities, whereas the putative halophiles, which contributed the most abundant transcripts, were in the majority of the active microbial population and is consistent with the soil salinity. Sample correlation analyses according to the detected and active genotypes showed significant differences, indicating high diversity of microbial communities among the Tarim soil samples. Regarding ecological functions based on the metatranscriptomic data, transcription of genes involved in various steps of nitrogen cycling, as well as carbon fixation, were observed in the tested soil samples. Metatranscriptomic data also indicated that Thaumarchaeota are crucial for ammonia oxidation and Proteobacteria play the most important role in other steps of nitrogen cycle. The reductive TCA pathway and dicarboxylate hydroxybutyrate cycle attributed to Proteobacteria and Crenarchaeota, respectively, were highly represented in carbon fixation. Our study reveals that the microbial communities could provide carbon and nitrogen nutrients for higher plants in the sandy saline soils of Tarim Basin. PMID- 29593682 TI - Root-Associated Fungi Shared Between Arbuscular Mycorrhizal and Ectomycorrhizal Conifers in a Temperate Forest. AB - Arbuscular mycorrhizal and ectomycorrhizal symbioses are among the most important drivers of terrestrial ecosystem dynamics. Historically, the two types of symbioses have been investigated separately because arbuscular mycorrhizal and ectomycorrhizal plant species are considered to host discrete sets of fungal symbionts (i.e., arbuscular mycorrhizal and ectomycorrhizal fungi, respectively). Nonetheless, recent studies based on high-throughput DNA sequencing technologies have suggested that diverse non-mycorrhizal fungi (e.g., endophytic fungi) with broad host ranges play roles in relationships between arbuscular mycorrhizal and ectomycorrhizal plant species in forest ecosystems. By analyzing an Illumina sequencing dataset of root-associated fungi in a temperate forest in Japan, we statistically examined whether co-occurring arbuscular mycorrhizal (Chamaecyparis obtusa) and ectomycorrhizal (Pinus densiflora) plant species could share non mycorrhizal fungal communities. Among the 919 fungal operational taxonomic units (OTUs) detected, OTUs in various taxonomic lineages were statistically designated as "generalists," which associated commonly with both coniferous species. The list of the generalists included fungi in the genera Meliniomyces, Oidiodendron, Cladophialophora, Rhizodermea, Penicillium, and Mortierella. Meanwhile, our statistical analysis also detected fungi preferentially associated with Chamaecyparis (e.g., Pezicula) or Pinus (e.g., Neolecta). Overall, this study provides a basis for future studies on how arbuscular mycorrhizal and ectomycorrhizal plant species interactively drive community- or ecosystem-scale processes. The physiological functions of the fungi highlighted in our host preference analysis deserve intensive investigations for understanding their roles in plant endosphere and rhizosphere. PMID- 29593683 TI - Commentary: Zika Virus in the Americas-Yet Another Arbovirus Threat. PMID- 29593681 TI - Intestinal Microbiota Influences Non-intestinal Related Autoimmune Diseases. AB - The human body is colonized by millions of microorganisms named microbiota that interact with our tissues in a cooperative and non-pathogenic manner. These microorganisms are present in the skin, gut, nasal, oral cavities, and genital tract. In fact, it has been described that the microbiota contributes to balancing the immune system to maintain host homeostasis. The gut is a vital organ where microbiota can influence and determine the function of cells of the immune system and contributes to preserve the wellbeing of the individual. Several articles have emphasized the connection between intestinal autoimmune diseases, such as Crohn's disease with dysbiosis or an imbalance in the microbiota composition in the gut. However, little is known about the role of the microbiota in autoimmune pathologies affecting other tissues than the intestine. This article focuses on what is known about the role that gut microbiota can play in the pathogenesis of non-intestinal autoimmune diseases, such as Grave's diseases, multiple sclerosis, type-1 diabetes, systemic lupus erythematosus, psoriasis, schizophrenia, and autism spectrum disorders. Furthermore, we discuss as to how metabolites derived from bacteria could be used as potential therapies for non-intestinal autoimmune diseases. PMID- 29593685 TI - The Use of a Chimeric Rhodopsin Vector for the Detection of New Proteorhodopsins Based on Color. AB - Student microbial ecology laboratory courses are often conducted as condensed courses in which theory and wet lab work are combined in a very intensive short time period. In last decades, the study of marine microbial ecology is increasingly reliant on molecular-based methods, and as a result many of the research projects conducted in such courses require sequencing that is often not available on site and may take more time than a typical course allows. In this work, we describe a protocol combining molecular and functional methods for analyzing proteorhodopsins (PRs), with visible results in only 4-5 days that do not rely on sequencing. PRs were discovered in oceanic surface waters two decades ago, and have since been observed in different marine environments and diverse taxa, including the abundant alphaproteobacterial SAR11 group. PR subgroups are currently known to absorb green and blue light, and their distribution was previously explained by prevailing light conditions - green pigments at the surface and blue pigments in deeper waters, as blue light travels deeper in the water column. To detect PR in environmental samples, we created a chimeric plasmid suitable for direct expression of PRs using PCR amplification and functional analysis in Escherichia coli cells. Using this assay, we discovered several exceptional cases of PRs whose phenotypes differed from those predicted based on sequence only, including a previously undescribed yellow-light absorbing PRs. We applied this assay in two 10-days marine microbiology courses and found it to greatly enhance students' laboratory experience, enabling them to gain rapid visual feedback and colorful reward for their work. Furthermore we expect this assay to promote the use of functional assays for the discovery of new rhodopsin variants. PMID- 29593684 TI - Group B Streptococcal Colonization, Molecular Characteristics, and Epidemiology. AB - Streptococcus agalactiae or group B streptococcus (GBS) is a leading cause of serious neonatal infections. GBS is an opportunistic commensal constituting a part of the intestinal and vaginal physiologic flora and maternal colonization is the principal route of GBS transmission. GBS is a pathobiont that converts from the asymptomatic mucosal carriage state to a major bacterial pathogen causing severe invasive infections. At present, as many as 10 serotypes (Ia, Ib, and II IX) are recognized. The aim of the current review is to shed new light on the latest epidemiological data and clonal distribution of GBS in addition to discussing the most important colonization determinants at a molecular level. The distribution and predominance of certain serotypes is susceptible to variations and can change over time. With the availability of multilocus sequence typing scheme (MLST) data, it became clear that GBS strains of certain clonal complexes possess a higher potential to cause invasive disease, while other harbor mainly colonizing strains. Colonization and persistence in different host niches is dependent on the adherence capacity of GBS to host cells and tissues. Bacterial biofilms represent well-known virulence factors with a vital role in persistence and chronic infections. In addition, GBS colonization, persistence, translocation, and invasion of host barriers are largely dependent on their adherence abilities to host cells and extracellular matrix proteins (ECM). Major adhesins mediating GBS interaction with host cells include the fibrinogen-binding proteins (Fbs), the laminin-binding protein (Lmb), the group B streptococcal C5a peptidase (ScpB), the streptococcal fibronectin binding protein A (SfbA), the GBS immunogenic bacterial adhesin (BibA), and the hypervirulent adhesin (HvgA). These adhesins facilitate persistent and intimate contacts between the bacterial cell and the host, while global virulence regulators play a major role in the transition to invasive infections. This review combines for first time epidemiological data with data on adherence and colonization for GBS. Investigating the epidemiology along with understanding the determinants of mucosal colonization and the development of invasive disease at a molecular level is therefore important for the development of strategies to prevent invasive GBS disease worldwide. PMID- 29593686 TI - Skin Microbiomes of California Terrestrial Salamanders Are Influenced by Habitat More Than Host Phylogeny. AB - A multitude of microorganisms live on and within plant and animal hosts, yet the ecology and evolution of these microbial communities remains poorly understood in many taxa. This study examined the extent to which environmental factors and host taxonomic identity explain microbiome variation within two salamander genera, Ensatina and Batrachoseps, in the family Plethodontidae. In particular, we assessed whether microbiome differentiation paralleled host genetic distance at three levels of taxonomy: genus and high and low clade levels within Ensatina eschscholtzii. We predicted that more genetically related host populations would have more similar microbiomes than more distantly related host populations. We found that salamander microbiomes possess bacterial species that are most likely acquired from their surrounding soil environment, but the relative representation of those bacterial species is significantly different on the skin of salamanders compared to soil. We found differences in skin microbiome alpha diversity among Ensatina higher and lower clade groups, as well as differences between Ensatina and Batrachoseps. We also found that relative microbiome composition (beta diversity) did vary between Ensatina lower clades, but differences were driven by only a few clades and not correlated to clade genetic distances. We conclude this difference was likely a result of Ensatina lower clades being associated with geographic location and habitat type, as salamander identity at higher taxonomic levels (genus and Ensatina higher clades) was a weak predictor of microbiome composition. These results lead us to conclude that environmental factors are likely playing a more significant role in salamander cutaneous microbiome assemblages than host-specific traits. PMID- 29593687 TI - Carrying Capacity and Colonization Dynamics of Curvibacter in the Hydra Host Habitat. AB - Most eukaryotic species are colonized by a microbial community - the microbiota - that is acquired during early life stages and is critical to host development and health. Much research has focused on the microbiota biodiversity during the host life, however, empirical data on the basic ecological principles that govern microbiota assembly is lacking. Here we quantify the contribution of colonizer order, arrival time and colonization history to microbiota assembly on a host. We established the freshwater polyp Hydra vulgaris and its dominant colonizer Curvibacter as a model system that enables the visualization and quantification of colonizer population size at the single cell resolution, in vivo, in real time. We estimate the carrying capacity of a single Hydra polyp as 2 * 105Curvibacter cells, which is robust among individuals and time. Colonization experiments reveal a clear priority effect of first colonizers that depends on arrival time and colonization history. First arriving colonizers achieve a numerical advantage over secondary colonizers within a short time lag of 24 h. Furthermore, colonizers primed for the Hydra habitat achieve a numerical advantage in the absence of a time lag. These results follow the theoretical expectations for any bacterial habitat with a finite carrying capacity. Thus, Hydra colonization and succession processes are largely determined by the habitat occupancy over time and Curvibacter colonization history. Our experiments provide empirical data on the basic steps of host-associated microbiota establishment - the colonization stage. The presented approach supplies a framework for studying habitat characteristics and colonization dynamics within the host-microbe setting. PMID- 29593688 TI - A Comprehensive Evaluation of Xpert MTB/RIF Assay With Bronchoalveolar Lavage Fluid as a Single Test or Combined With Conventional Assays for Diagnosis of Pulmonary Tuberculosis in China: A Two-Center Prospective Study. AB - Introduction: The Xpert MTB/RIF is recommended by the World Health Organization as a first line rapid test for the diagnosis of pulmonary tuberculosis (TB); however, China does not routinely use this test, partially due to the lack of a sufficient number of systematic evaluations of this assay in local patients. The aims of this study were to comprehensively assess the diagnostic performance of Xpert MTB/RIF, either alone or in combination with conventional assays for the diagnosis of pulmonary TB in adult Chinese patients. Methods: Xpert MTB/RIF tests were performed in 190 adult patients with suspected pulmonary TB, using bronchoalveolar lavage fluid (BALF) as test specimens. In parallel, conventional tests were carried out using the same BALF samples. Using two different reference standards, the performance of Xpert MTB/RIF, conventional assays and their combinations were evaluated. Results: Using mycobacterial culture as the reference comparator, Xpert MTB/RIF was found to be superior to smear-microscopy in detecting Mycobacterium tuberculosis. When final diagnosis, based on clinical criteria, was employed as the reference standard, Xpert MTB/RIF showed an even higher accuracy of 72.1%, supported by a sensitivity of 61.1% and specificity of 96.6%. Xpert MTB/RIF also demonstrated a powerful capability to identify pulmonary TB cases undetected by culture or smear-microscopy. Combining smear microscopy and Xpert MTB/RIF was found to be the most accurate early predictor for pulmonary TB. Rifampicin resistance reported by Xpert MTB/RIF slightly deviated from that by phenotypic antibiotic susceptibility testing and requires further study with a larger sample size. Conclusion: This two-center prospective study highlights the value of Xpert MTB/RIF with BALF in diagnosing pulmonary TB in adult Chinese patients. These findings might contribute to the optimization of current diagnostic algorithms for pulmonary TB in China. PMID- 29593689 TI - Comparative mRNA-Seq Analysis Reveals the Improved EPS Production Machinery in Streptococcus thermophilus ASCC 1275 During Optimized Milk Fermentation. AB - Exo-polysaccharide (EPS) produced by dairy starters plays critical roles in improving texture and functionalities of fermented dairy products. One of such high EPS producers, Streptococcus thermophilus ASCC 1275 (ST1275) was used as a model dairy strain to understand the stimulation of its EPS production under optimal milk fermentation conditions. The mRNA-seq analysis and targeted pathway analysis indicate that genes associated with lactose (milk sugar) catabolism, EPS assembly, proteolytic activity, and arginine/methionine/cysteine synthesis and transport in ST1275 were significantly up-regulated under the optimized conditions of pH 5.5, 40 degrees C, or WPI supplementation compared to that of pH 6.5 and 37 degrees C, respectively. This indicates that genes involved in above metabolisms cooperate together for improving EPS yield from ST1275. This study provides a global view map on potential targeted pathways and specific genes accounted for enhanced EPS production in Str. thermophilus and that could be modulated by fermentation conditions. PMID- 29593690 TI - A Validation Approach of an End-to-End Whole Genome Sequencing Workflow for Source Tracking of Listeria monocytogenes and Salmonella enterica. AB - Whole genome sequencing (WGS), using high throughput sequencing technology, reveals the complete sequence of the bacterial genome in a few days. WGS is increasingly being used for source tracking, pathogen surveillance and outbreak investigation due to its high discriminatory power. In the food industry, WGS used for source tracking is beneficial to support contamination investigations. Despite its increased use, no standards or guidelines are available today for the use of WGS in outbreak and/or trace-back investigations. Here we present a validation of our complete (end-to-end) WGS workflow for Listeria monocytogenes and Salmonella enterica including: subculture of isolates, DNA extraction, sequencing and bioinformatics analysis. This end-to-end WGS workflow was evaluated according to the following performance criteria: stability, repeatability, reproducibility, discriminatory power, and epidemiological concordance. The current study showed that few single nucleotide polymorphism (SNPs) were observed for L. monocytogenes and S. enterica when comparing genome sequences from five independent colonies from the first subculture and five independent colonies after the tenth subculture. Consequently, the stability of the WGS workflow for L. monocytogenes and S. enterica was demonstrated despite the few genomic variations that can occur during subculturing steps. Repeatability and reproducibility were also demonstrated. The WGS workflow was shown to have a high discriminatory power and has the ability to show genetic relatedness. Additionally, the WGS workflow was able to reproduce published outbreak investigation results, illustrating its capability of showing epidemiological concordance. The current study proposes a validation approach comprising all steps of a WGS workflow and demonstrates that the workflow can be applied to L. monocytogenes or S. enterica. PMID- 29593691 TI - Isolation, Identification, Prevalence, and Genetic Diversity of Bacillus cereus Group Bacteria From Different Foodstuffs in Tunisia. AB - Bacillus cereus group is widespread in nature and foods. Several members of this group are recognized as causing food spoilage and/or health issues. This study was designed to determine the prevalence and genetic diversity of the B. cereus group strains isolated in Tunisia from different foods (cereals, spices, cooked food, fresh-cut vegetables, raw and cooked poultry meats, seafood, canned, pastry, and dairy products). In total, 687 different samples were collected and searched for the presence of the B. cereus group after selective plating on MYP agar and enumeration of each sample. The typical pink-orange uniform colonies surrounded by a zone of precipitate were assumed to belong to the B. cereus group. One typical colony from each sample was subcultured and preserved as cryoculture. Overall, 191 (27.8%) food samples were found positive, giving rise to a collection of 191 B. cereus-like isolates. The concentration of B. cereus like bacteria were below 103 cfu/g or ml in 77.5% of the tested samples. Higher counts (>104 cfu/g or ml) were found in 6.8% of samples including fresh-cut vegetables, cooked foods, cereals, and pastry products. To verify whether B. cereus-like isolates belonged to the B. cereus group, a PCR test targeting the sspE gene sequence specific of the group was carried out. Therefore, 174 isolates were found to be positive. Food samples were contaminated as follows: cereals (67.6%), pastry products (46.2%), cooked food (40.8%), cooked poultry meat (32.7%), seafood products (32.3%), spices (28.8%), canned products (16.7%), raw poultry meat (9.4%), fresh-cut vegetables (5.0%), and dairy products (4.8%). The 174 B. cereus isolates were characterized by partial sequencing of the panC gene, using a Sym'Previous software tool to assign them to different phylogenetic groups. Strains were distributed as follows: 61.3, 29.5, 7.5, and 1.7% in the group III, IV, II, and V, respectively. The genetic diversity was further assessed by ERIC-PCR and PFGE typing methods. PFGE and ERIC-PCR patterns analysis allowed discriminating 143 and 99 different profiles, respectivey. These findings, associated to a relatively higher prevalence of B. cereus group in different foods, could be a significant etiological agent of food in Tunisia. PMID- 29593692 TI - Optimized Co-extraction and Quantification of DNA From Enteric Pathogens in Surface Water Samples Near Produce Fields in California. AB - Pathogen contamination of surface water is a health hazard in agricultural environments primarily due to the potential for contamination of crops. Furthermore, pathogen levels in surface water are often unreported or under reported due to difficulty with culture of the bacteria. The pathogens are often present, but require resuscitation, making quantification difficult. Frequently, this leads to the use of quantitative PCR targeted to genes unique to the pathogens. However, multiple pathogen types are commonly in the same water sample, both gram + and gram -, leading to problems with DNA extraction. With Shiga toxin-producing Escherichia coli (STEC), Salmonella enterica and Listeria monocytogenes as target, a method was optimized to co-extract all three and quantify the level of each using droplet digital PCR (ddPCR). Multiplexed target genes in STEC were virulence genes, shiga toxin 2 (stx2) and hemolysin (ehx). Likewise, multiplexed targets in Listeria and Salmonella were the virulence genes listeriolysin (hly) and invasion protein A (invA). Water samples were processed using microbiological techniques for each of the pathogens and duplicate water samples were quantified by ddPCR. A significant correlation was found between culture and ddPCR results indicating detection primarily of culturable cells by ddPCR. Average virulence gene levels were 923, 23 k, 69 and 152 copies per sample for stx2, ehx, hly and invA, respectively. Additionally, stx2, ehx and inv levels were significantly correlated (P < 0.05, R = 0.34) with generic E. coli MPN levels in the duplicate samples. Indirect quantification with ddPCR will improve understanding of prevalence of the pathogens and may reduce risks associated with contaminated surface water. PMID- 29593693 TI - Identification of Four Distinct Phylogenetic Groups in Flavobacterium columnare With Fish Host Associations. AB - Columnaris disease, caused by the Gram-negative bacterium Flavobacterium columnare, is one of the most prevalent fish diseases worldwide. An exceptionally high level of genetic diversity among isolates of F. columnare has long been recognized, whereby six established genomovars have been described to date. However, little has been done to quantify or characterize this diversity further in a systematic fashion. The objective of this research was to perform phylogenetic analyses of 16S rRNA and housekeeping gene sequences to decipher the genetic diversity of F. columnare. Fifty isolates and/or genomes of F. columnare, originating from diverse years, geographic locations, fish hosts, and representative of the six genomovars were analyzed in this study. A multilocus phylogenetic analysis (MLPA) of the 16S rRNA and six housekeeping genes supported four distinct F. columnare genetic groups. There were associations between genomovar and genetic group, but these relationships were imperfect indicating that genomovar assignment does not accurately reflect F. columnare genetic diversity. To expand the dataset, an additional 90 16S rRNA gene sequences were retrieved from GenBank and a phylogenetic analysis of this larger dataset also supported the establishment of four genetic groups. Examination of isolate historical data indicated biological relevance to the identified genetic diversity, with some genetic groups isolated preferentially from specific fish species or families. It is proposed that F. columnare isolates be assigned to the four genetic groups defined in this study rather than genomovar in order to facilitate a standard nomenclature across the scientific community. An increased understanding of which genetic groups are most prevalent in different regions and/or aquaculture industries may allow for the development of improved targeted control and treatment measures for columnaris disease. PMID- 29593694 TI - Amino Acid Substitutions HA A150V, PA A343T, and PB2 E627K Increase the Virulence of H5N6 Influenza Virus in Mice. AB - H5N6 avian influenza viruses (AIVs) can cause severe pneumonia and death in humans. However, the molecular determinants of H5N6 influenza virus mammalian adaption are still unclear. Three amino acid substitutions (HA A150V, PA A343T, PB2 E627K) are observed in H5N6 virus A/duck/Zhejiang/6D2/2013 (6D2) in lung-to lung passage in mice. These substitutions are crucial to the pathogenicity of mouse-adapted virus. In this study, we investigated the contribution of each amino acid substitution in the virus by reverse genetics. The results demonstrate that HA A150V greatly altered the receptor binding preference of 6D2. Virus bearing this substitution acquired increased mortality than mice infected with wild-type 6D2. The PA A343T substitution mildly enhanced viral polymerase activity but the reduced survival rate in mice indicates this substitution may change the immunoreaction of the host. The well-known PB2 E627K substitution increased eight folds the relative polymerase activity compared to PA A343T and resulted in 100% death rate in mice. In addition, we show that PA A343T dramatically exacerbates the effect of PB2 E627K on viral polymerase activity; when combined, these two substitutions work synergistically. However, HA A150V and PA A343T seemed to attenuate PB2 E627K in vivo, which implies the difference between mixed viral populations under natural condition and single population under experiment, specialization and cooperation in quasispecies is important in the process of adaption. This study suggests that HA A150V, PA A343T, and PB2 E627K are crucial in the adaption and increased pathogenicity of H5N6 in mammalian hosts. PMID- 29593695 TI - Research on Volatile Organic Compounds From Bacillus subtilis CF-3: Biocontrol Effects on Fruit Fungal Pathogens and Dynamic Changes During Fermentation. AB - The dynamic changes of the levels of volatile organic compounds (VOCs) produced by Bacillus subtilis CF-3 and their biocontrol effects on common fungal pathogens were researched in this study. The results showed that the VOCs in 24-h fermentation liquid (24hFL) of B. subtilis CF-3 inhibited mycelial growth of Botrytis cinerea, Colletotrichum gloeosporioides, Penicillium expansum, Monilinia fructicola, and Alternaria alternata, with a mean inhibition rate of 59.97%. The inhibitory effect on M. fructicola and C. gloeosporioides was the highest; they were therefore selected as target fungal pathogens for further experiments. Based on headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME-GC-MS), 74 potential VOCs were identified during the fermentation: 15 alcohols, 18 ketones, 4 pyrazines, 4 esters, 10 acids, 5 phenols, 3 hydrocarbons, 3 amines, 2 aldehydes, 5 ethers, and 5 other components. At different fermentation times, the type and content of VOCs were different. Most of the potential VOCs (62 VOCs) were identified in the 48hFL. The inhibition rates of all VOCs reached their peaks (73.46% on M. fructicola and 63.63% on C. gloeosporioides) in the 24hFL. Among the identified VOCs, 2,4-di-tert butylphenol, 1-octanol, and benzothiazole showed significant positive correlations with the rates of M. fructicola and C. gloeosporioides inhibition. Benzoic acid and benzaldehyde showed a significant positive correlation with the rates of M. fructicola inhibition, and anisole and 3-methylbutanal showed a significant positive correlation with the rates of C. gloeosporioides inhibition. In vitro, 2,4-di-tert-butylphenol showed a strong inhibitory effect on both M. fructicola and C. gloeosporioides. In vivo, benzothiazole showed the strongest inhibitory effect on the mycelial extensions of both M. fructicola and C. gloeosporioides, which also led to an increased rate of healthy fruit. The results of the present study clarified that 2,4-di-tert-butylthiophenol and benzothiazole are key inhibitory VOCs produced by B. subtilis CF-3.

AB - Aphid-transmitted plant viruses are a threat for major crops causing massive economic loss worldwide. Members in the Luteoviridae family are transmitted by aphids in a circulative and non-replicative mode. Virions are acquired by aphids when ingesting sap from infected plants and are transported through the gut and the accessory salivary gland (ASG) cells by a transcytosis mechanism relying on virus-specific receptors largely unknown. Once released into the salivary canal, virions are inoculated to plants, together with saliva, during a subsequent feeding. In this paper, we bring in vivo evidence that the membrane-bound Ephrin receptor (Eph) is a novel aphid protein involved in the transmission of the Turnip yellows virus (TuYV, Polerovirus genus, Luteoviridae family) by Myzus persicae. The minor capsid protein of TuYV, essential for aphid transmission, was able to bind the external domain of Eph in yeast. Feeding M. persicae on in planta- or in vitro-synthesized dsRNA targeting Eph-mRNA (dsRNAEph) did not affect aphid feeding behavior but reduced accumulation of TuYV genomes in the aphid's body. Consequently, TuYV transmission efficiency by the dsRNAEph-treated aphids was reproducibly inhibited and we brought evidence that Eph is likely involved in intestinal uptake of the virion. The inhibition of virus uptake after dsRNAEph acquisition was also observed for two other poleroviruses transmitted by M. persicae, suggesting a broader role of Eph in polerovirus transmission. Finally, dsRNAEph acquisition by aphids did not affect nymph production. These results pave the way toward an ecologically safe alternative of insecticide treatments that are used to lower aphid populations and reduce polerovirus damages.

AB - Emerging infectious disease is a growing threat to global health, and recent discoveries reveal that the microbiota dwelling on and within hosts can play an important role in health and disease. To understand the capacity of skin bacteria to protect amphibian hosts from the fungal disease chytridiomycosis caused by Batrachochytrium dendrobatidis (Bd), we isolated 192 bacterial morphotypes from the skin of 28 host species of frogs (families Bufonidae, Centrolenidae, Hemiphractidae, Hylidae, Leptodactylidae, Strabomantidae, and Telmatobiidae) collected from the eastern slopes of the Peruvian Andes (540-3,865 m a.s.l.) in the Kosnipata Valley near Manu National Park, a site where we previously documented the collapse of montane frog communities following chytridiomycosis epizootics. We obtained isolates through agar culture from skin swabs of wild frogs, and identified bacterial isolates by comparing 16S rRNA sequences against the GenBank database using BLAST. We identified 178 bacterial strains of 38 genera, including 59 bacterial species not previously reported from any amphibian host. The most common bacterial isolates were species of Pseudomonas, Paenibacillus, Chryseobacterium, Comamonas, Sphingobacterium, and Stenotrophomonas. We assayed the anti-fungal abilities of 133 bacterial isolates from 26 frog species. To test whether cutaneous bacteria might inhibit growth of the fungal pathogen, we used a local Bd strain isolated from the mouthparts of stream-dwelling tadpoles (Hypsiboas gladiator, Hylidae). We quantified Bd inhibition in vitro with co-culture assays. We found 20 bacterial isolates that inhibited Bd growth, including three isolates not previously known for such inhibitory abilities. Anti-Bd isolates occurred on aquatic and terrestrial breeding frogs across a wide range of elevations (560-3,695 m a.s.l.). The inhibitory ability of anti-Bd isolates varied considerably. The proportion of anti-Bd isolates was lowest at mid-elevations (6%), where amphibian declines have been steepest, and among hosts that are highly susceptible to chytridiomycosis (0 14%). Among non-susceptible species, two had the highest proportion of anti-Bd isolates (40 and 45%), but one common and non-susceptible species had a low proportion (13%). In conclusion, we show that anti-Bd bacteria are widely distributed elevationally and phylogenetically across frog species that have persisted in a region where chytridiomycosis emerged, caused a devastating epizootic and continues to infect amphibians.

PMID- 29593697 TI - HERV Envelope Proteins: Physiological Role and Pathogenic Potential in Cancer and Autoimmunity. AB - Human endogenous retroviruses (HERVs) are relics of ancient infections accounting for about the 8% of our genome. Despite their persistence in human DNA led to the accumulation of mutations, HERVs are still contributing to the human transcriptome, and a growing number of findings suggests that their expression products may have a role in various diseases. Among HERV products, the envelope proteins (Env) are currently highly investigated for their pathogenic properties, which could likely be participating to several disorders with complex etiology, particularly in the contexts of autoimmunity and cancer. In fact, HERV Env proteins have been shown, on the one side, to trigger both innate and adaptive immunity, prompting inflammatory, cytotoxic and apoptotic reactions; and, on the other side, to prevent the immune response activation, presenting immunosuppressive properties and acting as immune downregulators. In addition, HERV Env proteins have been shown to induce abnormal cell-cell fusion, possibly contributing to tumor development and metastasizing processes. Remarkably, even highly defective HERV env genes and alternative env splicing variants can provide further mechanisms of pathogenesis. A well-known example is the HERV-K(HML2) env gene that, depending on the presence or the absence of a 292-bp deletion, can originate two proteins of different length (Np9 and Rec) proposed to have oncogenic properties. The understanding of their involvement in complex pathological disorders made HERV Env proteins potential targets for therapeutic interventions. Of note, a monoclonal antibody directed against a HERV-W Env is currently under clinical trial as therapeutic approach for multiple sclerosis, representing the first HERV-based treatment. The present review will focus on the current knowledge of the HERV Env expression, summarizing its role in human physiology and its possible pathogenic effects in various cancer and autoimmune disorders. It moreover analyzes HERV Env possible exploitation for the development of innovative therapeutic strategies. PMID- 29593701 TI - Metabolic Phenotype Characterization of Botrytis cinerea, the Causal Agent of Gray Mold. AB - Botrytis cinerea, which causes gray mold, is an important pathogen in four important economic crops, tomato, tobacco, cucumber and strawberry, in China and worldwide. Metabolic phenomics data on B. cinerea isolates from these four crops were characterized and compared for 950 phenotypes with a BIOLOG Phenotype MicroArray (PM). The results showed that the metabolic fingerprints of the four B. cinerea isolates were similar to each other with minimal differences. B. cinerea isolates all metabolized more than 17% of the tested carbon sources, 63% of the amino acid nitrogen substrates, 80% of the peptide nitrogen substrates, 93% of the phosphorus substrates, and 97% of the sulfur substrates. Carbon substrates of organic acids and carbohydrates, and nitrogen substrates of amino acids and peptides were the significant utilization patterns for B. cinerea. Each B. cinerea isolate contained 94 biosynthetic pathways. These isolates showed a large range of adaptabilities and were still able to metabolize substrates in the presence of the osmolytes, including up to 6% potassium chloride, 10% sodium chloride, 5% sodium sulfate, 6% sodium formate, 20% ethylene glycol, and 3% urea. These isolates all showed active metabolism in environments with pH values from 3.5 to 8.5 and exhibited decarboxylase activities. These characterizations provide a theoretical basis for the study of B. cinerea in biochemistry and metabolic phenomics and provide valuable clues to finding potential new ways to manage gray mold. PMID- 29593700 TI - Identification and Characterization of Wheat Yellow Striate Virus, a Novel Leafhopper-Transmitted Nucleorhabdovirus Infecting Wheat. AB - A new wheat viral disease was found in China. Bullet-shaped viral particles within the nucleus of the infected wheat leave cells, which possessed 180-210 nm length and 35-40 nm width, were observed under transmission electron microscopy. A putative wheat-infecting rhabdovirus vectored by the leafhopper Psammotettix alienus was identified and tentatively named wheat yellow striate virus (WYSV). The full-length nucleotide sequence of WYSV was determined using transcriptome sequencing and RACE analysis of both wheat samples and leafhoppers P. alienus. The negative-sense RNA genome of WYSV contains 14,486 nucleotides (nt) and seven open reading frames (ORFs) encode deduced proteins in the order N-P-P3-M-P6-G-L on the antisense strand. In addition, WYSV genome has a 76-nt 3' leader RNA and a 258-nt 5' trailer, and the ORFs are separated by conserved intergenic sequences. The entire genome sequence shares 58.1 and 57.7% nucleotide sequence identity with two strains of rice yellow stunt virus (RYSV-A and RYSV-B) genomes, respectively. The highest amino acid sequence identity was 63.8% between the L proteins of the WYSV and RYSV-B, but the lowest was 29.5% between the P6 proteins of these viruses. Phylogenetic analysis firmly established WYSV as a new member of the genus Nucleorhabdovirus. Collectively, this study provided evidence that WYSV is likely the first nucleorhabdovirus described infecting wheat via leafhopper P. alienus transmission. PMID- 29593702 TI - Use of a Potential Probiotic, Lactobacillus plantarum L7, for the Preparation of a Rice-Based Fermented Beverage. AB - This study aimed to isolate potential probiotic lactic acid bacteria from a traditional rice-based fermented beverage "bhaati jaanr" and to evaluate their role during preparation of the beverage. Among various isolates, Lactobacillus plantarum strain L7 exhibited satisfactory in vitro probiotic characteristics such as acid resistance and bile tolerance, cell surface hydrophobicity, auto aggregation, antibiotic susceptibility, and antimicrobial activities. Therefore, performance of L7 as a starter culture in rice fermentation was determined during a 6-day rice fermentation study. L. plantarum L7 decreased the pH, associated with an increase in total titratable acidity and organic acid production up to the 4th day of fermentation. The highest concentrations of succinic acid (0.37 mg/g), lactic acid (4.95 mg/g), and acetic acid (0.36 mg/g) were recorded on the 3rd, 4th, and 5th days of fermentation, respectively. Saccharifying (148.13 MUg/min g-1) and liquefying (89.47 MUg/min g-1) activities were the highest on days 3 and 2, respectively, and thereafter, they decreased. Phytase activity and the cleavage of free minerals (sodium, calcium, magnesium, manganese, and ferrous) increased up to days 3-4. The concentration of various accumulated malto oligosaccharides (glucose, fructose, maltotriose, and maltoterose) was noted to be the maximum on days 4 and 5. Furthermore, gas chromatography-mass spectrometry analysis indicated the presence of various volatile compounds. The fermented material also exhibited 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3 ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity. Therefore, the probiotic, L. plantarum L7, has a significant role in the fermentation of this beverage and enhances its functional properties. PMID- 29593703 TI - Response of Nitrifier and Denitrifier Abundance and Microbial Community Structure to Experimental Warming in an Agricultural Ecosystem. AB - Soil microbial community plays an important role in terrestrial carbon and nitrogen cycling. However, the response of the soil nitrifier and denitrifier communities to climate warming is poorly understood. A long-term field warming experiment has been conducted for 8 years at Luancheng Experimental Farm Station on the North China Plain; we used this field to examine how soil microbial community structure, nitrifier, and denitrifier abundance respond to warming under regular irrigation (RI) and high irrigation (HI) at different soil depths (0-5, 5-10, and 10-20 cm). Nitrifier, denitrifier, and the total bacterial abundance were assessed by quantitative polymerase chain reaction of the functional genes and 16S rRNA gene, respectively. Bacterial community structure was studied through high throughput sequencing of the 16S rRNA gene. Under RI, warming significantly (P < 0.05) increased the potential nitrification rate and nitrate concentration and decreased the soil moisture. In most of the samples, warming increased the ammonia-oxidizing bacteria abundance but decreased the ammonia-oxidizing archaea (AOA) and denitrifier (nirK, nirS, and nosZ genes) abundance. Under HI, there was a highly increased AOA and 16S rRNA gene abundance and a slightly higher denitrifier abundance compared with RI. Warming decreased the bacterial diversity and species richness, and the microbial community structure differed greatly between the warmed and control plots. The decrease in bacterial diversity was higher in RI than HI and at the 0-5 cm depths than at the 5-10 and 10-20 cm soil depths. Warming led to an increase in the relative abundance of Actinobacteria, Bacteroidetes, and TM7 but a decrease in Acidobacteria, Alphaproteobacteria, Deltaproteobacteria, Nitrospira, and Planctomycetes. The greater shift in microbial community structure was observed only in RI at the 0-5 cm soil depth. This study provides new insight into our understanding of the nitrifier and denitrifier activity and microbial community response to climate warming in agricultural ecosystems.

PMID- 29593704 TI - Cellular Injuries in Cronobacter sakazakii CIP 103183T and Salmonella enterica Exposed to Drying and Subsequent Heat Treatment in Milk Powder. AB - Because of the ability of foodborne pathogens to survive in low-moisture foods, their decontamination is an important issue in food protection. This study aimed to clarify some of the cellular mechanisms involved in inactivation of foodborne pathogens after drying and subsequent heating. Individual strains of Salmonella Typhimurium, Salmonella Senftenberg, and Cronobacter sakazakii were mixed into whole milk powder and dried to different water activity levels (0.25 and 0.58); the number of surviving cells was determined after drying and subsequent thermal treatments in closed vessels at 90 and 100 degrees C, for 30 and 120 s. For each condition, the percentage of unculturable cells was estimated and, in parallel, membrane permeability and respiratory activity were estimated by flow cytometry using fluorescent probes. After drying, it was clearly observable that the percentage of unculturable cells was correlated with the percentage of permeabilized cells (responsible for 20-40% of the total inactivated bacteria after drying), and to a lesser degree with the percentage of cells presenting with loss of respiratory activity. In contrast, the percentages of unculturable cells observed after heat treatment were strongly correlated with the loss of respiratory activity and weakly with membrane permeability (for 70-80% of the total inactivated bacteria after heat treatment). We conclude that cell inactivation during drying is closely linked to membrane permeabilization and that heat treatment of dried cells affects principally their respiratory activity. These results legitimize the use of time-temperature scales and allow better understanding of the cellular mechanisms of bacterial death during drying and subsequent heat treatment. These results may also allow better optimization of the decontamination process to ensure food safety by targeting the most deleterious conditions for bacterial cells without denaturing the food product. PMID- 29593706 TI - Regulation of Human Natural Killer Cell IFN-gamma Production by MicroRNA-146a via Targeting the NF-kappaB Signaling Pathway. AB - Natural killer (NK) cells are one group of innate lymphocytes that are important for host defense against malignancy and viruses. MicroRNAs (miRNAs) play a critical role in regulating responses of immune cells including NK cells. Accumulating evidence suggests that miR-146a is involved in the regulation of immune responses. However, the mechanism by which miR-146a regulates NK cell function is largely unknown. In the current study, we found that miR-146a intrinsically regulated NK cell function. Forced overexpression of miR-146a decreased IFN-gamma production, whereas downregulation of miR-146a by anti-miR 146a significantly enhanced IFN-gamma production in the human NK-92 cell line and primary human NK cells upon stimulation with IL-12 or co-stimulation with IL-12 and IL-18. Mechanistically, miR-146a regulated IFN-gamma production via NF kappaB, as evidenced in NK-92 cells, by downregulation of NF-kappaB p65 phosphorylation when miR-146a was overexpressed but upregulation of NF-kappaB p65 phosphorylation when anti-miR-146a was overexpressed. miR-146a directly targeted IRAK1 and TRAF6, the upstream signaling components of the NF-kappaB signaling pathway. This direct targeting mechanism confirmed the above gain- and loss-of function approaches. However, the potent IFN-gamma-producing subset, CD56bright NK cells, expressed higher levels of miR-146a than the lesser IFN-gamma-producing subset, CD56dim NK cells. We also observed that co-stimulation of IL-12 and IL-18 significantly increased miR-146a expression in bulk NK cells and in the CD56bright subset in a time-dependent manner, correlating with augmented IFN gamma production. These data suggest that miR-146a plays a negative role in IFN gamma production by human NK cells and this miRNA may be critical in preventing NK cells from being super activated and overproducing IFN-gamma. PMID- 29593707 TI - The Immunomodulatory Effects of Macrolides-A Systematic Review of the Underlying Mechanisms. AB - Background: The mechanisms underlying the non-antimicrobial immunomodulatory properties of macrolides are not well understood. Objectives: To systematically review the evidence for the immunomodulatory properties of macrolides in humans and to describe the underlying mechanism and extent of their influence on the innate and adaptive immune system. Methods: A systematic literature search was done in MEDLINE using the OVID interface from 1946 to December 2016 according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA). Original articles investigating the influence of four macrolides (azithromycin, clarithromycin, erythromycin, and roxithromycin) on immunological markers in humans were included. Results: We identified 22 randomized, controlled trials, 16 prospective cohort studies, and 8 case-control studies investigating 47 different immunological markers (186 measurements) in 1,834 participants. The most frequently reported outcomes were a decrease in the number of neutrophils, and the concentrations of neutrophil elastase, interleukin (IL)-8, IL-6, IL-1beta, tumor necrosis factor (TNF)-alpha, eosinophilic cationic protein, and matrix metalloproteinase 9. Inhibition of neutrophil function was reported more frequently than eosinophil function. A decrease in T helper (Th) 2 cells cytokines (IL-4, IL-5, IL-6) was reported more frequently than a decrease in Th1 cytokines (IL-2, INF-gamma). Conclusion: Macrolides influence a broad range of immunological mechanisms resulting in immunomodulatory effects. To optimize the treatment of chronic inflammatory diseases by macrolides, further studies are necessary, particularly comparing different macrolides and dose effect relationships. PMID- 29593708 TI - Mucosal Delivery of Fusion Proteins with Bacillus subtilis Spores Enhances Protection against Tuberculosis by Bacillus Calmette-Guerin. AB - Tuberculosis (TB) is the most deadly infectious disease in existence, and the only available vaccine, Bacillus Calmette-Guerin (BCG), is almost a century old and poorly protective. The immunological complexity of TB, coupled with rising resistance to antimicrobial therapies, necessitates a pipeline of diverse novel vaccines. Here, we show that Bacillus subtilis spores can be coated with a fusion protein 1 ("FP1") consisting of Mycobacterium tuberculosis (Mtb) antigens Ag85B, ACR, and HBHA. The resultant vaccine, Spore-FP1, was tested in a murine low-dose Mtb aerosol challenge model. Mice were primed with subcutaneous BCG, followed by mucosal booster immunizations with Spore-FP1. We show that Spore-FP1 enhanced pulmonary control of Mtb, as evidenced by reduced bacterial burdens in the lungs. This was associated with elevated antigen-specific IgG and IgA titers in the serum and lung mucosal surface, respectively. Spore-FP1 immunization generated superior antigen-specific memory T-cell proliferation in both CD4+ and CD8+ compartments, alongside bolstered Th1-, Th17-, and Treg-type cytokine production, compared to BCG immunization alone. CD69+CD103+ tissue resident memory T-cells (Trm) were found within the lung parenchyma after mucosal immunization with Spore FP1, confirming the advantages of mucosal delivery. Our data show that Spore-FP1 is a promising new TB vaccine that can successfully augment protection and immunogenicity in BCG-primed animals. PMID- 29593709 TI - Hypertonic Saline Suppresses NADPH Oxidase-Dependent Neutrophil Extracellular Trap Formation and Promotes Apoptosis. AB - Tonicity of saline (NaCl) is important in regulating cellular functions and homeostasis. Hypertonic saline is administered to treat many inflammatory diseases, including cystic fibrosis. Excess neutrophil extracellular trap (NET) formation, or NETosis, is associated with many pathological conditions including chronic inflammation. Despite the known therapeutic benefits of hypertonic saline, its underlying mechanisms are not clearly understood. Therefore, we aimed to elucidate the effects of hypertonic saline in modulating NETosis. For this purpose, we purified human neutrophils and induced NETosis using agonists such as diacylglycerol mimetic phorbol myristate acetate (PMA), Gram-negative bacterial cell wall component lipopolysaccharide (LPS), calcium ionophores (A23187 and ionomycin from Streptomyces conglobatus), and bacteria (Pseudomonas aeruginosa and Staphylococcus aureus). We then analyzed neutrophils and NETs using Sytox green assay, immunostaining of NET components and apoptosis markers, confocal microscopy, and pH sensing reagents. This study found that hypertonic NaCl suppresses nicotinamide adenine dinucleotide phosphate oxidase (NADPH2 or NOX2) dependent NETosis induced by agonists PMA, Escherichia coli LPS (0111:B4 and O128:B12), and P. aeruginosa. Hypertonic saline also suppresses LPS- and PMA- induced reactive oxygen species production. It was determined that supplementing H2O2 reverses the suppressive effect of hypertonic saline on NOX2-dependent NETosis. Many of the aforementioned suppressive effects were observed in the presence of equimolar concentrations of choline chloride and osmolytes (d mannitol and d-sorbitol). This suggests that the mechanism by which hypertonic saline suppresses NOX2-dependent NETosis is via neutrophil dehydration. Hypertonic NaCl does not significantly alter the intracellular pH of neutrophils. We found that hypertonic NaCl induces apoptosis while suppressing NOX2-dependent NETosis. In contrast, hypertonic solutions do not suppress NOX2-independent NETosis. Although hypertonic saline partially suppresses ionomycin-induced NETosis, it enhances A23187-induced NETosis, and it does not alter S. aureus induced NETosis. Overall, this study determined that hypertonic saline suppresses NOX2-dependent NETosis induced by several agonists; in contrast, it has variable effects on neutrophil death induced by NOX2-independent NETosis agonists. These findings are important in understanding the regulation of NETosis and apoptosis in neutrophils. PMID- 29593710 TI - Heterologous Prime-Boost Combinations Highlight the Crucial Role of Adjuvant in Priming the Immune System. AB - The induction and modulation of the immune response to vaccination can be rationally designed by combining different vaccine formulations for priming and boosting. Here, we investigated the impact of heterologous prime-boost approaches on the vaccine-specific cellular and humoral responses specific for a mycobacterial vaccine antigen. C57BL/6 mice were primed with the chimeric vaccine antigen H56 administered alone or with the CAF01 adjuvant, and boosted with H56 alone, or combined with CAF01 or with the squalene-based oil-in-water emulsion adjuvant (o/w squalene). A strong secondary H56-specific CD4+ T cell response was recalled by all the booster vaccine formulations when mice had been primed with H56 and CAF01, but not with H56 alone. The polyfunctional nature of T helper cells was analyzed and visualized with the multidimensional flow cytometry FlowSOM software, implemented as a package of the R environment. A similar cytokine profile was detected in groups primed with H56 + CAF01 and boosted with or without adjuvant, except for some clusters of cells expressing high level of IL-17 together with TNF-alpha, IL-2, and IFN-gamma, that were significantly upregulated only in groups boosted with the adjuvants. On the contrary, the comparison between groups primed with or without the adjuvant showed a completely different clusterization of cells, strengthening the impact of the formulation used for primary immunization on the profiling of responding cells. The presence of the CAF01 adjuvant in the priming formulation deeply affected also the secondary humoral response, especially in groups boosted with H56 alone or o/w squalene. In conclusion, the presence of CAF01 adjuvant in the primary immunization is crucial for promoting primary T and B cell responses that can be efficiently reactivated by booster immunization also performed with antigen alone. PMID- 29593712 TI - Mitochondrial Sirtuin 4 Resolves Immune Tolerance in Monocytes by Rebalancing Glycolysis and Glucose Oxidation Homeostasis. AB - The goal of this investigation was to define the molecular mechanism underlying physiologic conversion of immune tolerance to resolution of the acute inflammatory response, which is unknown. An example of this knowledge gap and its clinical importance is the broad-based energy deficit and immunometabolic paralysis in blood monocytes from non-survivors of human and mouse sepsis that precludes sepsis resolution. This immunometabolic dysregulation is biomarked by ex vivo endotoxin tolerance to increased glycolysis and TNF-alpha expression. To investigate how tolerance switches to resolution, we adapted our previously documented models associated with acute inflammatory, immune, and metabolic reprogramming that induces endotoxin tolerance as a model of sepsis in human monocytes. We report here that mitochondrial sirtuin 4 (SIRT4) physiologically breaks tolerance and resolves acute inflammation in human monocytes by coordinately reprogramming of metabolism and bioenergetics. We find that increased SIRT4 mRNA and protein expression during immune tolerance counters the increase in pyruvate dehydrogenase kinase 1 (PDK1) and SIRT1 that promote tolerance by switching glucose-dependent support of immune resistance to fatty acid oxidation support of immune tolerance. By decreasing PDK1, pyruvate dehydrogenase complex reactivation rebalances mitochondrial respiration, and by decreasing SIRT1, SIRT4 represses fatty acid oxidation. The precise mechanism for the mitochondrial SIRT4 nuclear feedback is unclear. Our findings are consistent with a new concept in which mitochondrial SIRT4 directs the axis that controls anabolic and catabolic energy sources. PMID- 29593711 TI - Regenerating Immunotolerance in Multiple Sclerosis with Autologous Hematopoietic Stem Cell Transplant. AB - Multiple sclerosis (MS) is an inflammatory disorder of the central nervous system where evidence implicates an aberrant adaptive immune response in the accrual of neurological disability. The inflammatory phase of the disease responds to immunomodulation to varying degrees of efficacy; however, no therapy has been proven to arrest progression of disability. Recently, more intensive therapies, including immunoablation with autologous hematopoietic stem cell transplantation (AHSCT), have been offered as a treatment option to retard inflammatory disease, prior to patients becoming irreversibly disabled. Empirical clinical observations support the notion that the immune reconstitution (IR) that occurs following AHSCT is associated with a sustained therapeutic benefit; however, neither the pathogenesis of MS nor the mechanism by which AHSCT results in a therapeutic benefit has been clearly delineated. Although the antigenic target of the aberrant immune response in MS is not defined, accumulated data suggest that IR following AHSCT results in an immunotolerant state through deletion of pathogenic clones by a combination of direct ablation and induction of a lymphopenic state driving replicative senescence and clonal attrition. Restoration of immunoregulation is evidenced by changes in regulatory T cell populations following AHSCT and normalization of genetic signatures of immune homeostasis. Furthermore, some evidence exists that AHSCT may induce a rebooting of thymic function and regeneration of a diversified naive T cell repertoire equipped to appropriately modulate the immune system in response to future antigenic challenge. In this review, we discuss the immunological mechanisms of IR therapies, focusing on AHSCT, as a means of recalibrating the dysfunctional immune response observed in MS. PMID- 29593713 TI - Variable Extent of Lineage-Specificity and Developmental Stage-Specificity of Cohesin and CCCTC-Binding Factor Binding Within the Immunoglobulin and T Cell Receptor Loci. AB - CCCTC-binding factor (CTCF) is largely responsible for the 3D architecture of the genome, in concert with the action of cohesin, through the creation of long-range chromatin loops. Cohesin is hypothesized to be the main driver of these long range chromatin interactions by the process of loop extrusion. Here, we performed ChIP-seq for CTCF and cohesin in two stages each of T and B cell differentiation and examined the binding pattern in all six antigen receptor (AgR) loci in these lymphocyte progenitors and in mature T and B cells, ES cells, and fibroblasts. The four large AgR loci have many bound CTCF sites, most of which are only occupied in lymphocytes, while only the CTCF sites at the end of each locus near the enhancers or J genes tend to be bound in non-lymphoid cells also. However, despite the generalized lymphocyte restriction of CTCF binding in AgR loci, the Igkappa locus is the only locus that also shows significant lineage-specificity (T vs. B cells) and developmental stage-specificity (pre-B vs. pro-B) in CTCF binding. We show that cohesin binding shows greater lineage- and stage specificity than CTCF at most AgR loci, providing more specificity to the loops. We also show that the culture of pro-B cells in IL7, a common practice to expand the number of cells before ChIP-seq, results in a CTCF-binding pattern resembling pre-B cells, as well as other epigenetic and transcriptional characteristics of pre-B cells. Analysis of the orientation of the CTCF sites show that all sites within the large V portions of the Igh and TCRbeta loci have the same orientation. This suggests either a lack of requirement for convergent CTCF sites creating loops, or indicates an absence of any loops between CTCF sites within the V region portion of those loci but only loops to the convergent sites at the D-J-enhancer end of each locus. The V region portions of the Igkappa and TCRalpha/delta loci, by contrast, have CTCF sites in both orientations, providing many options for creating CTCF-mediated convergent loops throughout the loci. CTCF/cohesin loops, along with transcription factors, drives contraction of AgR loci to facilitate the creation of a diverse repertoire of antibodies and T cell receptors.

AB - Using the CRISPR/Cas9 gene-editing technology, we recently produced a number of rabbits with mutations in immune function genes, including FOXN1, PRKDC, RAG1, RAG2, and IL2RG. Seven founder knockout rabbits (F0) and three male IL2RG null ( /y) F1 animals demonstrated severe combined immunodeficiency (SCID), characterized by absence or pronounced hypoplasia of the thymus and splenic white pulp, and absence of immature and mature T and B-lymphocytes in peripheral blood. Complete blood count analysis showed severe leukopenia and lymphocytopenia accompanied by severe neutrophilia. Without prophylactic antibiotics, the SCID rabbits universally succumbed to lung infections following weaning. Pathology examination revealed severe heterophilic bronchopneumonia caused by Bordetella bronchiseptica in several animals, but a consistent feature of lung lesions in all animals was a severe interstitial pneumonia caused by Pneumocystis oryctolagi, as confirmed by histological examination and PCR analysis of Pneumocystis genes. The results of this study suggest that these SCID rabbits could serve as a useful model for human SCID to investigate the disease pathogenesis and the development of gene and drug therapies. PMID- 29593715 TI - Comparative Analysis of the Regulatory T Cells Dynamics in Peripheral Blood in Human and Porcine Polytrauma. AB - Background: Severely injured patients experience substantial immunological stress in the aftermath of traumatic insult, which often results in systemic immune dysregulation. Regulatory T cells (Treg) play a key role in the suppression of the immune response and in the maintenance of immunological homeostasis. Little is known about their presence and dynamics in blood after trauma, and nothing is known about Treg in the porcine polytrauma model. Here, we assessed different subsets of Treg in trauma patients (TP) and compared those to either healthy volunteers (HV) or data from porcine polytrauma. Methods: Peripheral blood was withdrawn from 20 TP with injury severity score (ISS) >=16 at the admittance to the emergency department (ED), and subsequently on day 1 and at day 3. Ten HV were included as controls (ctrl). The porcine polytrauma model consisted of a femur fracture, liver laceration, lung contusion, and hemorrhagic shock resulting in an ISS of 27. After polytrauma, the animals underwent resuscitation and surgical fracture fixation. Blood samples were withdrawn before and immediately after trauma, 24 and 72 h later. Different subsets of Treg, CD4+CD25+, CD4+CD25+FoxP3+, CD4+CD25+CD127-, and CD4+CD25+CD127-FoxP3+ were characterized by flow cytometry. Results: Absolute cell counts of leukocytes were significantly increasing after trauma, and again decreasing in the follow-up in human and porcine samples. The proportion of human Treg in the peripheral blood of TP admitted to the ED was lower when compared to HV. Their numbers did not recover until 72 h after trauma. Comparable data were found for all subsets. The situation in the porcine trauma model was comparable with the clinical data. In porcine peripheral blood before trauma, we could identify Treg with the typical immunophenotype (CD4+CD25+CD127-), which were virtually absent immediately after trauma. Similar to the human situation, most of these cells expressed FoxP3, as assessed by intracellular FACS stain. Conclusion: Despite minor percental differences in the recovery of Treg populations after trauma, our findings show a comparable decrease of Treg early after polytrauma, and strengthen the immunological significance of the porcine polytrauma model. Furthermore, the Treg subpopulation CD4+CD25+CD127- was characterized in porcine samples. PMID- 29593716 TI - Mycobacterium tuberculosis Infection and Innate Responses in a New Model of Lung Alveolar Macrophages. AB - Lung alveolar macrophages (AMs) are in the first line of immune defense against respiratory pathogens and play key roles in the pathogenesis of Mycobacterium tuberculosis (Mtb) in humans. Nevertheless, AMs are available only in limited amounts for in vitro studies, which hamper the detailed molecular understanding of host-Mtb interactions in these macrophages. The recent establishment of the self-renewing and primary Max Planck Institute (MPI) cells, functionally very close to lung AMs, opens unique opportunities for in vitro studies of host pathogen interactions in respiratory diseases. Here, we investigated the suitability of MPI cells as a host cell system for Mtb infection. Bacterial, cellular, and innate immune features of MPI cells infected with Mtb were characterized. Live bacteria were readily internalized and efficiently replicated in MPI cells, similarly to primary murine macrophages and other cell lines. MPI cells were also suitable for the determination of anti-tuberculosis (TB) drug activity. The primary innate immune response of MPI cells to live Mtb showed significantly higher and earlier induction of the pro-inflammatory cytokines TNFalpha, interleukin 6 (IL-6), IL-1alpha, and IL-1beta, as compared to stimulation with heat-killed (HK) bacteria. MPI cells previously showed a lack of induction of the anti-inflammatory cytokine IL-10 to a wide range of stimuli, including HK Mtb. By contrast, we show here that live Mtb is able to induce significant amounts of IL-10 in MPI cells. Autophagy experiments using light chain 3B immunostaining, as well as LysoTracker labeling of acidic vacuoles, demonstrated that MPI cells efficiently control killed Mtb by elimination through phagolysosomes. MPI cells were also able to accumulate lipid droplets in their cytoplasm following exposure to lipoproteins. Collectively, this study establishes the MPI cells as a relevant, versatile host cell model for TB research, allowing a deeper understanding of AMs functions in this pathology. PMID- 29593718 TI - Secretion of the Phosphorylated Form of S100A9 from Neutrophils Is Essential for the Proinflammatory Functions of Extracellular S100A8/A9. AB - S100A8 and S100A9 are members of the S100 family of cytoplasmic EF-hand Ca2+ binding proteins and are abundantly expressed in the cytosol of neutrophils. In addition to their intracellular roles, S100A8/A9 can be secreted in the extracellular environment and are considered as alarmins able to amplify the inflammatory response. The intracellular activity of S100A8/A9 was shown to be regulated by S100A9 phosphorylation, but the importance of this phosphorylation on the extracellular activity of S100A8/A9 has not yet been extensively studied. Our work focuses on the impact of the phosphorylation state of secreted S100A9 on the proinflammatory function of neutrophils. In a first step, we characterized the secretion of S100A8/A9 in different stimulatory conditions and investigated the phosphorylation state of secreted S100A9. Our results on neutrophil-like differentiated HL-60 (dHL-60) cells and purified human neutrophils showed a time dependent secretion of S100A8/A9 when induced by phorbol 12-myristoyl 13-acetate and this secreted S100A9 was found in a phosphorylated form. Second, we evaluated the impact of this phosphorylation on proinflammatory cytokine expression and secretion in dHL-60 cells. Time course experiments with purified unphosphorylated or phosphorylated S100A8/A9 were performed and the expression and secretion levels of interleukin (IL)-1alpha, IL-1beta, IL-6, tumor necrosis factor alpha, CCL2, CCL3, CCL4, and CXCL8 were measured by real-time PCR and cytometry bead array, respectively. Our results demonstrate that only the phosphorylated form of the complex induces proinflammatory cytokine expression and secretion. For the first time, we provide evidence that S100A8/PhosphoS100A9 is inducing cytokine secretion through toll-like receptor 4 signaling. PMID- 29593717 TI - Tumor Necrosis Factor alpha and Regulatory T Cells in Oncoimmunology. AB - Tumor necrosis factor alpha (TNF) is a potent pro-inflammatory cytokine that has deleterious effect in some autoimmune diseases, which led to the use of anti-TNF drugs in some of these diseases. However, some rare patients treated with these drugs paradoxically develop an aggravation of their disease or new onset autoimmunity, revealing an immunosuppressive facet of TNF. A possible mechanism of this observation is the direct and positive effect of TNF on regulatory T cells (Tregs) through its binding to the TNF receptor type 2 (TNFR2). Indeed, TNF is able to increase expansion, stability, and possibly function of Tregs via TNFR2. In this review, we discuss the role of TNF in graft-versus-host disease as an example of the ambivalence of this cytokine in the pathophysiology of an immunopathology, highlighting the therapeutic potential of triggering TNFR2 to boost Treg expansion. We also describe new targets in immunotherapy of cancer, emphasizing on the putative suppressive effect of TNF in antitumor immunity and of the interest of blocking TNFR2 to regulate the Treg compartment. PMID- 29593719 TI - Human Milk Oligosaccharide 2'-Fucosyllactose Improves Innate and Adaptive Immunity in an Influenza-Specific Murine Vaccination Model. AB - Background: Human milk is uniquely suited to provide optimal nutrition and immune protection to infants. Human milk oligosaccharides are structural complex and diverse consisting of short chain and long chain oligosaccharides typically present in a 9:1 ratio. 2'-Fucosyllactose (2'FL) is one of the most prominent short chain oligosaccharides and is associated with anti-infective capacity of human milk. Aim: To determine the effect of 2'FL on vaccination responsiveness (both innate and adaptive) in a murine influenza vaccination model and elucidate mechanisms involved. Methods: A dose range of 0.25-5% (w/w) dietary 2'FL was provided to 6-week-old female C57Bl/6JOlaHsd mice 2 weeks prior primary and booster vaccination until the end of the experiment. Intradermal (i.d.) challenge was performed to measure the vaccine-specific delayed-type hypersensitivity (DTH). Antigen-specific antibody levels in serum as well as immune cell populations within several organs were evaluated using ELISA and flow cytometry, respectively. In an ex vivo restimulation assay, spleen cells were cocultured with influenza-loaded bone marrow-derived dendritic cells (BMDCs) to study the effects of 2'FL on vaccine-specific CD4+ and CD8+ T-cell proliferation and cytokine secretions. Furthermore, the direct immune regulatory effects of 2'FL were confirmed using in vitro BMDCs T-cell cocultures. Results: Dietary 2'FL significantly (p < 0.05) enhanced vaccine specific DTH responses accompanied by increased serum levels of vaccine-specific immunoglobulin (Ig) G1 and IgG2a in a dose-dependent manner. Consistently, increased activation marker (CD27) expression on splenic B-cells was detected in mice receiving 2'FL as compared to control mice. Moreover, proliferation of vaccine-specific CD4+ and CD8+ T-cells, as well as interferon-gamma production after ex vivo restimulation were significantly increased in spleen cells of mice receiving 2'FL as compared to control mice, which were in line with changes detected within dendritic cell populations. Finally, we confirmed a direct effect of 2'FL on the maturation status and antigen presenting capacity of BMDCs. Conclusion: Dietary intervention with 2'FL improves both humoral and cellular immune responses to vaccination in mice, which might be attributed in part to the direct effects of 2'FL on immune cell differentiation. PMID- 29593720 TI - The Soluble Form of Toll-Like Receptor 2 Is Elevated in Serum of Multiple Sclerosis Patients: A Novel Potential Disease Biomarker. AB - Multiple sclerosis (MS) is an immune-mediated inflammatory demyelinating disease of the central nervous system. It was previously shown that toll-like receptor (TLR)-2 signaling plays a key role in the murine experimental autoimmune encephalomyelitis (EAE) model of MS, and that TLR2-stimulation of regulatory T cells (Tregs) promotes their conversion to T helper 17 (Th17) cells. Here, we sought potential sources of TLR2 stimulation and evidence of TLR2 activity in MS patient clinical samples. Soluble TLR2 (sTLR2) was found to be significantly elevated in sera of MS patients (n = 21), in both relapse and remission, compared to healthy controls (HC) (n = 24). This was not associated with the acute phase reaction (APR) as measured by serum C-reactive protein (CRP) level, which was similarly increased in MS patients compared to controls. An independent validation cohort from a different ethnic background showed a similar upward trend in mean sTLR2 values in relapsing-remitting MS (RRMS) patients, and significant differences in sTLR2 values between patients and HC were preserved when the data from the two cohorts were pooled together (n = 41 RRMS and 44 HC, P = 0.0006). TLR2-stimulants, measured using a human embryonic kidney (HEK)-293 cells transfectant reporter assay, were significantly higher in urine of MS patients than HC. A screen of several common urinary tract infections (UTI) related organisms showed strong induction of TLR2-signaling in the same assay. Taken together, these results indicate that two different markers of TLR2 activity-urinary TLR2-stimulants and serum sTLR2 levels-are significantly elevated in MS patients compared to HC. PMID- 29593721 TI - Vitamin D in Human Immunodeficiency Virus Infection: Influence on Immunity and Disease. AB - People living with human immunodeficiency virus (HIV) infection typically have hypovitaminosis D, which is linked to a large number of pathologies, including immune disorders and infectious diseases. Vitamin D (VitD) is a key regulator of host defense against infections by activating genes and pathways that enhance innate and adaptive immunity. VitD mediates its biological effects by binding to the Vitamin D receptor (VDR), and activating and regulating multiple cellular pathways. Single nucleotide polymorphisms in genes from those pathways have been associated with protection from HIV-1 infection. High levels of VitD and VDR expression are also associated with natural resistance to HIV-1 infection. Conversely, VitD deficiency is linked to more inflammation and immune activation, low peripheral blood CD4+ T-cells, faster progression of HIV disease, and shorter survival time in HIV-infected patients. VitD supplementation and restoration to normal values in HIV-infected patients may improve immunologic recovery during combination antiretroviral therapy, reduce levels of inflammation and immune activation, and increase immunity against pathogens. Additionally, VitD may protect against the development of immune reconstitution inflammatory syndrome events, pulmonary tuberculosis, and mortality among HIV-infected patients. In summary, this review suggests that VitD deficiency may contribute to the pathogenesis of HIV infection. Also, VitD supplementation seems to reverse some alterations of the immune system, supporting the use of VitD supplementation as prophylaxis, especially in individuals with more severe VitD deficiency. PMID- 29593722 TI - Formation of Foamy Macrophages by Tuberculous Pleural Effusions Is Triggered by the Interleukin-10/Signal Transducer and Activator of Transcription 3 Axis through ACAT Upregulation. AB - The ability of Mycobacterium tuberculosis (Mtb) to persist in its human host relies on numerous immune evasion strategies, such as the deregulation of the lipid metabolism leading to the formation of foamy macrophages (FM). Yet, the specific host factors leading to the foamy phenotype of Mtb-infected macrophages remain unknown. Herein, we aimed to address whether host cytokines contribute to FM formation in the context of Mtb infection. Our approach is based on the use of an acellular fraction of tuberculous pleural effusions (TB-PE) as a physiological source of local factors released during Mtb infection. We found that TB-PE induced FM differentiation as observed by the increase in lipid bodies, intracellular cholesterol, and expression of the scavenger receptor CD36, as well as the enzyme acyl CoA:cholesterol acyl transferase (ACAT). Importantly, interleukin-10 (IL-10) depletion from TB-PE prevented the augmentation of all these parameters. Moreover, we observed a positive correlation between the levels of IL-10 and the number of lipid-laden CD14+ cells among the pleural cells in TB patients, demonstrating that FM differentiation occurs within the pleural environment. Downstream of IL-10 signaling, we noticed that the transcription factor signal transducer and activator of transcription 3 was activated by TB-PE, and its chemical inhibition prevented the accumulation of lipid bodies and ACAT expression in macrophages. In terms of the host immune response, TB-PE-treated macrophages displayed immunosuppressive properties and bore higher bacillary loads. Finally, we confirmed our results using bone marrow-derived macrophage from IL-10-/- mice demonstrating that IL-10 deficiency partially prevented foamy phenotype induction after Mtb lipids exposure. In conclusion, our results evidence a role of IL-10 in promoting the differentiation of FM in the context of Mtb infection, contributing to our understanding of how alterations of the host metabolic factors may favor pathogen persistence. PMID- 29593723 TI - Analyzing Immunoglobulin Repertoires. AB - Somatic assembly of T cell receptor and B cell receptor (BCR) genes produces a vast diversity of lymphocyte antigen recognition capacity. The advent of efficient high-throughput sequencing of lymphocyte antigen receptor genes has recently generated unprecedented opportunities for exploration of adaptive immune responses. With these opportunities have come significant challenges in understanding the analysis techniques that most accurately reflect underlying biological phenomena. In this regard, sample preparation and sequence analysis techniques, which have largely been borrowed and adapted from other fields, continue to evolve. Here, we review current methods and challenges of library preparation, sequencing and statistical analysis of lymphocyte receptor repertoire studies. We discuss the general steps in the process of immune repertoire generation including sample preparation, platforms available for sequencing, processing of sequencing data, measurable features of the immune repertoire, and the statistical tools that can be used for analysis and interpretation of the data. Because BCR analysis harbors additional complexities, such as immunoglobulin (Ig) (i.e., antibody) gene somatic hypermutation and class switch recombination, the emphasis of this review is on Ig/BCR sequence analysis. PMID- 29593725 TI - Perilipin 1 Mediates Lipid Metabolism Homeostasis and Inhibits Inflammatory Cytokine Synthesis in Bovine Adipocytes. AB - Dairy cows with ketosis displayed lipid metabolic disorder and high inflammatory levels. Adipose tissue is an active lipid metabolism and endocrine tissue and is closely related to lipid metabolism homeostasis and inflammation. Perilipin 1 (PLIN1), an adipocyte-specific lipid-coated protein, may be involved in the above physiological function. The aim of this study is to investigate the role of PLIN1 in lipid metabolism regulation and inflammatory factor synthesis in cow adipocytes. The results showed that PLIN1 overexpression upregulated the expression of fatty acid and triglyceride (TAG) synthesis molecule sterol regulator element-binding protein-1c (SREBP-1c) and its target genes, diacylglycerol acyltransferase (DGAT) 1, and DGAT2, but inhibited the expression of lipolysis enzymes hormone-sensitive lipase (HSL) and CGI-58 for adipose triglyceride lipase (ATGL), thus augmenting the fatty acids and TAG synthesis and inhibiting lipolysis. Importantly, PLIN1 overexpression inhibited the activation of the NF-kappaB inflammatory pathway and decreased the expression and content of tumor necrosis factor alpha (TNF-alpha), interleukin 1 beta (IL-1beta), and interleukin 6 (IL-6) induced by lipopolysaccharide. Conversely, PLIN1 silencing inhibited TAG synthesis, promoted lipolysis, and overinduced the activation of the NF-kappaB inflammatory pathway in cow adipocytes. In ketotic cows, the expression of PLIN1 was markedly decreased, whereas lipid mobilization, NF-kappaB pathway, and downstream inflammatory cytokines were overinduced in adipose tissue. Taken together, these results indicate that PLIN1 can maintain lipid metabolism homeostasis and inhibit the NF-kappaB inflammatory pathway in adipocytes. However, low levels of PLIN1 reduced the inhibitory effect on fat mobilization, NF-kappaB pathway, and inflammatory cytokine synthesis in ketotic cows. PMID- 29593724 TI - miRNome Expression Analysis Reveals New Players on Leprosy Immune Physiopathology. AB - Leprosy remains as a public health problem and its physiopathology is still not fully understood. MicroRNAs (miRNA) are small RNA non-coding that can interfere with mRNA to regulate gene expression. A few studies using DNA chip microarrays have explored the expression of miRNA in leprosy patients using a predetermined set of genes as targets, providing interesting findings regarding the regulation of immune genes. However, using a predetermined set of genes restricted the possibility of finding new miRNAs that might be involved in different mechanisms of disease. Thus, we examined the miRNome of tuberculoid (TT) and lepromatous (LL) patients using both blood and lesional biopsies from classical leprosy patients (LP) who visited the Dr. Marcello Candia Reference Unit in Sanitary Dermatology in the State of Para and compared them with healthy subjects. Using a set of tools to correlate significantly differentially expressed miRNAs with their gene targets, we identified possible interactions and networks of miRNAs that might be involved in leprosy immunophysiopathology. Using this approach, we showed that the leprosy miRNA profile in blood is distinct from that in lesional skin as well as that four main groups of genes are the targets of leprosy miRNA: (1) recognition and phagocytosis, with activation of immune effector cells, where the immunosuppressant profile of LL and immunoresponsive profile of TT are clearly affected by miRNA expression; (2) apoptosis, with supportive data for an antiapoptotic leprosy profile based on BCL2, MCL1, and CASP8 expression; (3) Schwann cells (SCs), demyelination and epithelial-mesenchymal transition (EMT), supporting a role for different developmental or differentiation gene families, such as Sox, Zeb, and Hox; and (4) loss of sensation and neuropathic pain, revealing that RHOA, ROCK1, SIGMAR1, and aquaporin-1 (AQP1) may be involved in the loss of sensation or leprosy pain, indicating possible new therapeutic targets. Additionally, AQP1 may also be involved in skin dryness and loss of elasticity, which are well known signs of leprosy but with unrecognized physiopathology. In sum, miRNA expression reveals new aspects of leprosy immunophysiopathology, especially on the regulation of the immune system, apoptosis, SC demyelination, EMT, and neuropathic pain. PMID- 29593726 TI - Pretransplant IgA-Anti-Beta 2 Glycoprotein I Antibodies As a Predictor of Early Graft Thrombosis after Renal Transplantation in the Clinical Practice: A Multicenter and Prospective Study. AB - Background: Graft thrombosis is a devastating complication after renal transplantation. We recently described the association of anti-beta-2 glycoprotein-I (IgA-ab2GP1) antibodies with early graft loss mainly caused by thrombosis in a monocenter study. Methods: Multicenter prospective observational cohort study. Setting and participants: Seven hundred forty patients from five hospitals of the Spanish Forum Renal Group transplanted from 2000 to 2002 were prospectively followed-up for 10 years. Outcomes: Early graft loss and graft loss by thrombosis. Measurements: The presence of IgA anti-B2GP1 antibodies in pretransplant serum was examined using the same methodology in all the patients. Results: At transplantation, 288 patients were positive for IgA-B2GP1 (39%, Group 1) and the remaining were negative (Group-2). Graft loss at 6 months was higher in Group-1 (12.5 vs. 4.2% p < 0.001), vessel thrombosis being the most frequent cause of early graft loss, especially in Group-1 (6.9 vs. 0.4% p < 0.001). IgA aB2GP1 was the most important independent risk factor for graft thrombosis (hazard ratio: 13.83; 95% CI: 3.17-60.27, p < 0.001). Furthermore, the, presence of IgA-aB2GP1 was associated with early graft loss and delayed graft function. At 10 years, survival figures were also lower in Group-1: graft survival was lower compared with Group-2 (60.4 vs. 76.8%, p < 0.001). Mortality was significantly higher in Group-1 (19.8 vs. 12.2%, p = 0.005). Limitations: Patients were obtained during a 3-year period (1 January 2000-31 December 2002) and kidneys were only transplanted from brain-dead donors. Nowadays, the patients are older and the percentage of sensitized and retransplants is high. Conclusion: In a prospective observational multicenter study, we were able to corroborate that pretransplant presence of IgA-aB2GP1 was the main risk factor for graft thrombosis and early graft loss. Therefore, a prospective study is needed to evaluate the efficacy and safety of prophylactic anticoagulation to avoid this severe complication. PMID- 29593727 TI - Effect of VH-VL Families in Pertuzumab and Trastuzumab Recombinant Production, Her2 and FcgammaIIA Binding. AB - Many therapeutic antibodies are humanized from animal sources. In the humanization process, complementarity determining region grafting is tedious and highly prone to failure. With seven known VH families, and up to six known kappa VL families, there are choices aplenty. However, the functions of these families remain largely enigmatic. To study the role of these V-region families, we made 84 recombinant combinations of the various VH and VL family whole IgG1 variants of both Trastuzumab and Pertuzumab. We managed to purify 66 of these to investigate the biophysical characteristics: recombinant protein production, and both Her2 and FcgammaIIA binding. Our findings revealed combinations that showed improved recombinant antibody production and both antigen and receptor binding kinetics. These findings show the need to rethink antibodies as a whole protein, relooking of the functions of the antibody domains, and the need to include immunoglobulin receptor investigations for effective antibody therapeutics development. PMID- 29593728 TI - The Acid-Base Balance and Gender in Inflammation: A Mini-Review. AB - In humans, acid-base balance is crucial to cell homeostasis. Acidosis is observed in numerous inflammatory processes, primarily acute conditions such as sepsis, trauma, or acute respiratory distress where females tend to exhibit better prognosis compared with males. The mechanisms underlying these gender-dependent differences are multiple, probably involving hormonal and genetic factors, particularly the X chromosome. Although pH influences multiple immunological functions, gender differences in acid-base balance have been poorly investigated. In this review, we provide an update on gender differences in human susceptibility to inflammatory diseases. We additionally discuss the potential impact of acid-base balance on the gender bias of the inflammatory response in view of our recent observation that girls present higher neutrophilic inflammation and lower pH with a trend toward better prognosis in severe sepsis. We also highlight the potent role played by endothelial cells in gender differences of inflammation through activation of proton-sensing G protein coupled receptors. PMID- 29593730 TI - CD5L Promotes M2 Macrophage Polarization through Autophagy-Mediated Upregulation of ID3. AB - CD5L (CD5 molecule-like) is a secreted glycoprotein that controls key mechanisms in inflammatory responses, with involvement in processes such as infection, atherosclerosis, and cancer. In macrophages, CD5L promotes an anti-inflammatory cytokine profile in response to TLR activation. In the present study, we questioned whether CD5L is able to influence human macrophage plasticity, and drive its polarization toward any specific phenotype. We compared CD5L-induced phenotypic and functional changes to those caused by IFN/LPS, IL4, and IL10 in human monocytes. Phenotypic markers were quantified by RT-qPCR and flow cytometry, and a mathematical algorithm was built for their analysis. Moreover, we compared ROS production, phagocytic capacity, and inflammatory responses to LPS. CD5L drove cells toward a polarization similar to that induced by IL10. Furthermore, IL10- and CD5L-treated macrophages showed increased LC3-II content and colocalization with acidic compartments, thereby pointing to the enhancement of autophagy-dependent processes. Accordingly, siRNA targeting ATG7 in THP1 cells blocked CD5L-induced CD163 and Mer tyrosine kinase mRNA and efferocytosis. In these cells, gene expression profiling and validation indicated the upregulation of the transcription factor ID3 by CD5L through ATG7. In agreement, ID3 silencing reversed polarization by CD5L. Our data point to a significant contribution of CD5L-mediated autophagy to the induction of ID3 and provide the first evidence that CD5L drives macrophage polarization. PMID- 29593729 TI - Genomic Effects of the Vitamin D Receptor: Potentially the Link between Vitamin D, Immune Cells, and Multiple Sclerosis. AB - Vitamin D has a plethora of functions that are important for the maintenance of general health and in particular, the functional integrity of the immune system, such as promoting an anti-inflammatory cytokine profile and reducing the Treg/Th17 ratio. Multiple sclerosis (MS) is a chronic, inflammatory, and neurodegenerative central nervous system (CNS) disorder of probable autoimmune origin. MS is characterized by recurring or progressive demyelination and degeneration of the CNS due in part to a misguided immune response to as yet undefined (CNS) antigens, potentially including myelin basic protein and proteolipid protein. MS has also been shown to be associated significantly with environmental factors such as the lack of vitamin D. The role of vitamin D in the pathogenesis and progression of MS is complex. Recent genetic studies have shown that various common MS-associated risk-single-nucleotide polymorphisms (SNPs) are located within or in the vicinity of genes associated with the complex metabolism of vitamin D. The functional aspects of these genetic associations may be explained either by a direct SNP-associated loss- or gain-of-function in a vitamin D-associated gene or due to a change in the regulation of gene expression in certain immune cell types. The development of new genetic tools using next generation sequencing: e.g., chromatin immunoprecipitation sequencing (ChIP-seq) and the accompanying rapid progress of epigenomics has made it possible to recognize that the association between vitamin D and MS could be based on the extensive and characteristic genomic binding of the vitamin D receptor (VDR). Therefore, it is important to analyze comprehensively the spatiotemporal VDR binding patterns that have been identified using ChIP-seq in multiple immune cell types to reveal an integral profile of genomic VDR interaction. In summary, the aim of this review is to connect genomic effects vitamin D has on immune cells with MS and thus, to contribute to a better understanding of the influence of vitamin D on the etiology and the pathogenesis of this complex autoimmune disease. PMID- 29593731 TI - Transcriptional Regulation of Emergency Granulopoiesis in Leukemia. AB - Neutropenic conditions are prevalent in leukemia patients and are often associated with increased susceptibility to infections. In fact, emergency granulopoiesis (EG), a process regulating neutrophil homeostasis in inflammatory conditions and infections, may occur improperly in leukemic conditions, leading to reduced neutrophil counts. Unfortunately, the mechanisms central to dysfunctional EG remain understudied in both leukemia patients and leukemic mouse models. However, despite no direct studies on EG response in leukemia are reported, recently certain transcription factors (TFs) have been found to function at the crossroads of leukemia and EG. In this review, we present an update on TFs that can potentially govern the fate of EG in leukemia. Transcriptional control of Fanconi DNA repair pathway genes is also highlighted, as well as the newly discovered role of Fanconi proteins in innate immune response and EG. Identifying the TFs regulating EG in leukemia and dissecting their underlying mechanisms may facilitate the discovery of therapeutic drugs for the treatment of neutropenia. PMID- 29593732 TI - A Distinct T Follicular Helper Cell Subset Infiltrates the Brain in Murine Neuropsychiatric Lupus. AB - Neuropsychiatric symptoms in systemic lupus erythematosus (SLE) are not uncommon, yet the mechanisms underlying disease initiation and progression in the brain are incompletely understood. Although the role of T cells in other lupus target organs such as the kidney is well defined, which T cells contribute to the pathogenesis of neuropsychiatric SLE is not known. The present study was aimed at characterizing the CD4 T cell populations that are present in the choroid plexus (CP) of MRL/MpJ-faslpr mice, the primary site of brain infiltration in this classic lupus mouse model which exhibits a prominent neurobehavioral phenotype. T cells infiltrating the CP of MRL/MpJ-faslpr mice were characterized and subset identification was done by multiparameter flow cytometry. We found that the infiltrating CD4 T cells are activated and have an effector phenotype. Importantly, CD4 T cells have a T follicular helper cell (TFH) like phenotype, as evidenced by their surface markers and signature cytokine, IL-21. In addition, CD4 TFH cells also secrete significant levels of IFN-gamma and express Bcl-6, thereby conforming to a potentially pathogenic T helper population that can drive the disease progression. Interestingly, the regulatory axis comprising CD4 T regulatory cells is diminished. These results suggest that accumulation of CD4 TFH in the brain of MRL/MpJ-faslpr mice may contribute to the neuropsychiatric manifestations of SLE, and point to this T cell subset as a possible novel therapeutic candidate. PMID- 29593733 TI - Computational Insight Into the Structural Organization of Full-Length Toll-Like Receptor 4 Dimer in a Model Phospholipid Bilayer. AB - Toll-like receptors (TLRs) are a unique category of pattern recognition receptors that recognize distinct pathogenic components, often utilizing the same set of downstream adaptors. Specific molecular features of extracellular, transmembrane (TM), and cytoplasmic domains of TLRs are crucial for coordinating the complex, innate immune signaling pathway. Here, we constructed a full-length structural model of TLR4-a widely studied member of the interleukin-1 receptor/TLR superfamily-using homology modeling, protein-protein docking, and molecular dynamics simulations to understand the differential domain organization of TLR4 in a membrane-aqueous environment. Results showed that each functional domain of the membrane-bound TLR4 displayed several structural transitions that are biophysically essential for plasma membrane integration. Specifically, the extracellular and cytoplasmic domains were partially immersed in the upper and lower leaflets of the membrane bilayer. Meanwhile, TM domains tilted considerably to overcome the hydrophobic mismatch with the bilayer core. Our analysis indicates an alternate dimerization or a potential oligomerization interface of TLR4-TM. Moreover, the helical properties of an isolated TM dimer partly agree with that of the full-length receptor. Furthermore, membrane-absorbed or solvent exposed surfaces of the toll/interleukin-1 receptor domain are consistent with previous X-ray crystallography and biochemical studies. Collectively, we provided a complete structural model of membrane-bound TLR4 that strengthens our current understanding of the complex mechanism of receptor activation and adaptor recruitment in the innate immune signaling pathway. PMID- 29593734 TI - Experimental Demyelination and Axonal Loss Are Reduced in MicroRNA-146a Deficient Mice. AB - Background: The cuprizone (CPZ) model of multiple sclerosis (MS) was used to identify microRNAs (miRNAs) related to in vivo de- and remyelination. We further investigated the role of miR-146a in miR-146a-deficient (KO) mice: this miRNA is differentially expressed in MS lesions and promotes differentiation of oligodendrocyte precursor cells (OPCs) during remyelination, but its role has not been examined during demyelination. Methods: MicroRNAs were examined by Agilent Mouse miRNA Microarray in the corpus callosum during CPZ-induced demyelination and remyelination. Demyelination, axonal loss, changes in number of oligodendrocytes, OPCs, and macrophages/microglia was compared by histology/immunohistochemistry between KO and WT mice. Differential expression of target genes and proteins of miR-146a was analyzed in the transcriptome (4 * 44K Agilent Whole Mouse Genome Microarray) and proteome (liquid chromatography tandem mass spectrometry) of CPZ-induced de- and remyelination in WT mice. Levels of proinflammatory molecules in the corpus callosum were compared in WT versus KO mice by Meso Scale Discovery multiplex protein analysis. Results: miR-146a was increasingly upregulated during CPZ-induced de- and remyelination. The absence of miR-146a in KO mice protected against demyelination, axonal loss, body weight loss, and atrophy of thymus and spleen. The number of CNP+ oligodendrocytes was increased during demyelination in the miR-146a KO mice, while there was a trend of increased number of NG2+ OPCs in the WT mice. miR-146a target genes, SNAP25 and SMAD4, were downregulated in the proteome of demyelinating corpus callosum in WT mice. Higher levels of SNAP25 were measured by ELISA in the corpus callosum of miR-146a KO mice, but there was no difference between KO and WT mice during demyelination. Multiplex protein analysis of the corpus callosum lysate revealed upregulated TNF-RI, TNF-RII, and CCL2 in the WT mice in contrast to KO mice. The number of Mac3+ and Iba1+ macrophages/microglia was reduced in the demyelinating corpus callosum of the KO mice. Conclusion: During demyelination, absence of miR 146a reduced inflammatory responses, demyelination, axonal loss, the number of infiltrating macrophages, and increased the number of myelinating oligodendrocytes. The number of OPCs was slightly higher in the WT mice during remyelination, indicating a complex role of miR-146a during in vivo de- and remyelination. PMID- 29593735 TI - Involvement of Macrophage Inflammatory Protein-1 Family Members in the Development of Diabetic Neuropathy and Their Contribution to Effectiveness of Morphine. AB - Current investigations underline the important roles of C-C motif ligands in the development of neuropathic pain; however, their participation in diabetic neuropathy is still undefined. Therefore, the goal of our study was to evaluate the participation of macrophage inflammatory protein-1 (MIP-1) family members (CCL3, CCL4, CCL9) in a streptozotocin (STZ)-induced mouse model of diabetic neuropathic pain. Single intrathecal administration of each MIP-1 member (10, 100, or 500 ng/5 MUl) in naive mice evoked hypersensitivity to mechanical (von Frey test) and thermal (cold plate test) stimuli. Concomitantly, protein analysis has shown that, 7 days following STZ injection, the levels of CCL3 and CCL9 (but not CCL4) are increased in the lumbar spinal cord. Performed additionally, immunofluorescence staining undoubtedly revealed that CCL3, CCL9, and their receptors (CCR1 and CCR5) are expressed predominantly by neurons. In vitro studies provided evidence that the observed expression of CCL3 and CCL9 may be partially of glial origin; however, this observation was only partially possible to confirm by immunohistochemical study. Single intrathecal administration of CCL3 or CCL9 neutralizing antibody (2 and 4 MUg/5 MUl) delayed neuropathic pain symptoms as measured at day 7 following STZ administration. Single intrathecal injection of a CCR1 antagonist (J113863; 15 and 20 MUg/5 MUl) also attenuated pain-related behavior as evaluated at day 7 after STZ. Both neutralizing antibodies, as well as the CCR1 antagonist, enhanced the effectiveness of morphine in STZ-induced diabetic neuropathy. These findings highlight the important roles of CCL3 and CCL9 in the pathology of diabetic neuropathic pain and suggest that they play pivotal roles in opioid analgesia. PMID- 29593736 TI - Type I Interferon-Independent Dendritic Cell Priming and Antitumor T Cell Activation Induced by a Mycoplasma fermentans Lipopeptide. AB - Mycoplasma fermentans-derived diacylated lipoprotein M161Ag (MALP404) is recognized by human/mouse toll-like receptor (TLR) 2/TLR6. Short proteolytic products including macrophage-activating lipopeptide 2 (MALP2) have been utilized as antitumor immune-enhancing adjuvants. We have chemically synthesized a short form of MALP2 named MALP2s (S-[2,3-bis(palmitoyloxy)propyl]-CGNNDE). MALP2 and MALP2s provoke natural killer (NK) cell activation in vitro but only poorly induce tumor regression using in vivo mouse models loading NK-sensitive tumors. Here, we identified the functional mechanism of MALP2s on dendritic cell (DC) priming and cytotoxic T lymphocyte (CTL)-dependent tumor eradication using CTL sensitive tumor-implant models EG7 and B16-OVA. Programmed death ligand-1 (PD-L1) blockade therapy in combination with MALP2s + ovalbumin (OVA) showed a significant additive effect on tumor growth suppression. MALP2s increased co stimulators CD80/86 and CD40, which were totally MyD88-dependent, with no participation of toll-IL-1R homology domain-containing adaptor molecule-1 or type I interferon signaling in DC priming. MALP2s + OVA consequently augmented proliferation of OVA-specific CTLs in the spleen and at tumor sites. Chemokines and cytolytic factors were upregulated in the tumor. Strikingly, longer duration and reinvigoration of CTLs in spleen and tumors were accomplished by the addition of MALP2s + OVA to alpha-PD-L1 antibody (Ab) therapy compared to alpha-PD-L1 Ab monotherapy. Then, tumors regressed better in the MALP2s/OVA combination than in the alpha-PD-L1 Ab monotherapy. Hence, MALP2s/tumor-associated antigens combined with alpha-PD-L1 Ab is a good therapeutic strategy in some mouse models. Unfortunately, numerous patients are still resistant to PD-1/PD-L1 blockade, and good DC-priming adjuvants are desired. Cytokine toxicity by MALP2s remains to be settled, which should be improved by chemical modification in future studies. PMID- 29593737 TI - Overall Downregulation of mRNAs and Enrichment of H3K4me3 Change Near Genome-Wide Association Study Signals in Systemic Lupus Erythematosus: Cell-Specific Effects. AB - This study was designed to define gene expression and H3K4me3 histone modifications in T cells, B cells, and monocytes in systemic lupus erythematosus (SLE). Array studies of total peripheral blood mononuclear cells have demonstrated gene expression signatures related to neutrophils, interferon, and other inflammatory pathways. It is not clear how consistent these effects are across different cell types. In this study, RNA-seq and chromatin immunoprecipitation-seq were utilized to identify gene expression patterns and H3K4me3 histone modifications related to promoter activation in SLE. Across the three cell types, there was 55% concordance for gene expression changes related to SLE. Key conserved pathways were ribosome biogenesis among upregulated genes and heat shock response among downregulated genes. ETS family transcription factors (TFs) and STAT1 were revealed as common regulators by position weight matrices. When epigenetic changes were leveraged with gene expression, the pivotal TFs ATF3 and FOS were defined with ATF3 also cross-referencing with gene expression-identified TFs. Genome-wide association study (GWAS) single nucleotide polymorphisms associated with SLE were cross-referenced with both mRNA and H3K4me3 changes in SLE. Baseline mRNA expression and H3K4me3 peak height was higher at sites that cross-referenced with GWAS signals, however, all three cell types exhibited an overall decrease in expression of GWAS-associated RNAs differentially expressed in SLE. H3K4me3 changes in SLE were also enriched in GWAS-associated sites. In summary, the SLE disease process is associated with both shared and cell-specific changes in gene expression and epigenetics. Surprisingly, GWAS-associated RNAs were overall markedly decreased across all three cell types. TF analysis identified ATF3, FOS, STAT1, and ETS family members as critical, all pathways with a recognized relationship to the SLE disease process. GWAS signals clearly mark both cell-type specific changes in SLE as well as concordant changes across all three cell types. Interpretation of single nucleotide polymorphism effects in SLE will require tissue-specific mechanistic studies and therapeutics will require mechanistic studies in multiple cell types. PMID- 29593738 TI - Prostaglandin E2 Inhibits Group 2 Innate Lymphoid Cell Activation and Allergic Airway Inflammation Through E-Prostanoid 4-Cyclic Adenosine Monophosphate Signaling. AB - Evidence is accumulating that group 2 innate lymphoid cells (ILC2) play an important role in allergic airway inflammation by producing a large amount of type 2 cytokines. But it remains poorly understood how its activities are properly controlled in vivo. Here, we demonstrated that prostaglandin E2 (PGE2) had a profound inhibitory effect on IL-33-induced ILC2 expansion and IL-5 and IL 13 production in vitro. This effect was mimicked by PGE1-alcohol but attenuated by ONO-AE3-208, indicating a selective action through the E-prostanoid 4 (EP4) receptor. In the IL-33-induced asthma model, coadministration of PGE2 or PGE1 alcohol resulted in diminished IL-5 and IL-13 production, reduced eosinophilia and alleviated lung pathology. In contrast, EP4-deficient mice displayed an exacerbated inflammatory response in another ILC2-mediated asthma model induced by Alternaria extract. Mechanistic studies demonstrated that the PGE2-mediated inhibition of ILC2 was dependent on cyclic adenosine monophosphate (cAMP) production. Further downstream, PGE2-EP4-cAMP signaling led to suppression of GATA3 and ST2 expression, which is known to be critical for ILC2 activation. These findings reveal a novel function of PGE2 as a negative regulator of ILC2 activation and highlight an endogenous counter-regulatory mechanism for the control of innate allergic inflammatory responses. PMID- 29593739 TI - STAT6 Mediates Footpad Immunopathology in the Absence of IL-12p40 Following Infection of Susceptible BALB/c Mice With Leishmania major. AB - Leishmania major (L. major) parasites are intracellular parasites belong to the Trypanosomatidae family and are the causative agent of cutaneous leishmaniasis. This disease affects approximately 1.5 million per year worldwide and there is currently no prophylactic vaccine available. L. major is transmitted by the bite of an infected sandfly and has been considered for decades now as a mouse model of choice to identify the factors implicated in T helper (Th)1 and Th2 polarization due to the natural resistance and susceptibility to infection of C57BL/6 and BALB/c mice, respectively. In this study, we refine the role of IL 12p40 cytokine, which is implicated the development of a protective Th1 response, and STAT6, a transcription factor involved in the signaling via detrimental interleukin (IL)-4 and IL-13 associated Th2 cytokines during L. major infection in the BALB/c model. In the absence of STAT6 and IL-12p40 signaling, double knockout (DKO) susceptible BALB/c mice displayed reduced footpad swelling and ulcerative lesion compared to IL-12p40-/- mice upon L. major infection. Hence, they expressed slower upregulation of keratinocyte markers implicated in the inhibition of wound healing, such as keratin 6a (Krt6a) and Krt16. This coincides with the presence of neutrophils displaying an altered phenotype characterized by a lower expression of surface markers Ly6C, CD11b, and Ly6G. These neutrophils exhibited very lower levels of apoptosis similarly to neutrophils present in resistant STAT6-/- mice. Interestingly, the reduced footpad swelling in DKO mice is associated with a high footpad parasite level similar to susceptible IL-12p40 /- mice. In conclusion, this study demonstrate that in the absence of both STAT6 and IL-12p40 signaling, L. major-infected mice display smaller and less ulcerated lesions, which does, however, not correlate with reduced parasite load. In addition, the presence of neutrophils with an altered phenotype is associated with reduced apoptosis and delayed immunopathologies, demonstrating the detrimental role of STAT6 in infected susceptible BALB/c mice.

AB - Native C-reactive protein (nCRP) is a non-specific marker of inflammation being claimed as a bystander in several chronic disorders. Accumulating evidence indicates that nCRP dissociates to and acts primarily as the monomeric conformation (mCRP) at inflammatory loci. This suggests that mCRP may be a superior disease marker with improved specificity and clear causality to the underlying pathogenesis. However, the lack of a feasible assay to quantify mCRP in clinical samples precludes the assessment of that suggestion. Here we report the development of a sandwich ELISA assay for quantification of plasma mCRP using commercially available reagents. Our assay is reproducible and highly conformation-specific showing a reliable detection limit of 1 ng/mL. We further show that mCRP appears to be a better marker than nCRP in several skin-related autoimmune disorders. This assay thus provides a useful tool to examine the clinical significance and utility of mCRP.

PMID- 29593743 TI - Therapeutic Potential of Invariant Natural Killer T Cells in Autoimmunity. AB - Tolerance against self-antigens is regulated by a variety of cell types with immunoregulatory properties, such as CD1d-restricted invariant natural killer T (iNKT) cells. In many experimental models of autoimmunity, iNKT cells promote self-tolerance and protect against autoimmunity. These findings are supported by studies with patients suffering from autoimmune diseases. Based on these studies, the therapeutic potential of iNKT cells in autoimmunity has been explored. Many of these studies have been performed with the potent iNKT cell agonist KRN7000 or its structural variants. These findings have generated promising results in several autoimmune diseases, although mechanisms by which iNKT cells modulate autoimmunity remain incompletely understood. Here, we will review these preclinical studies and discuss the prospects for translating their findings to patients suffering from autoimmune diseases. PMID- 29593744 TI - Studies of Mast Cells: Adventures in Serendipity. AB - Like many of us who had the great fortune to work with Bill Paul, my science life was immeasurably altered by my interactions with him. Although intimidating at first because of his stature in the immunology world, it was soon clear that he not only truly cared about the specific research we were doing together, but he wished to convey to his trainees an approach to science that was open, always questioning, and infinitely fun. His enthusiasm was infectious and after my training with him, despite stresses due to funding and publishing hurdles, I never regretted the path I took. My research took a sharp turn from the studies of adaptive immunity I had planned on pursuing after my fellowship with Bill to a life long quest to understand the wonders of the mast cell, a relatively rare innate immune cell. This came about because Bill's curiosity and expectation of the unexpected allowed him to view, in retrospect, a rather mundane observation we made together involving a non-physiological transformed mast cell line as something that might be really interesting. I have never forgotten that lesson: Look at the data with an eye on the big picture. Sometimes the unexpected is more interesting than predicted results. His example in this regard was incredibly important when as an independent investigator a mistake in mouse sex determination led to unexpected and very confusing data. Yet, these data ultimately revealed a role for mast cells in male-specific protection in experimental autoimmune encephalomyelitis, the mouse model of multiple sclerosis. Bill's influence in immunology is far-reaching and will continue to be felt as those of us who train our own students and post-doctoral fellows pass on his wisdom and approach to scientific research. PMID- 29593745 TI - Integral Roles for Integrins in gammadelta T Cell Function. AB - Integrins are adhesion receptors on the cell surface that enable cells to respond to their environment. Most integrins are heterodimers, comprising alpha and beta type I transmembrane glycoprotein chains with large extracellular domains and short cytoplasmic tails. Integrins deliver signals through multiprotein complexes at the cell surface, which interact with cytoskeletal and signaling proteins to influence gene expression, cell proliferation, morphology, and migration. Integrin expression on gammadelta T cells (gammadeltaTc) has not been systematically investigated; however, reports in the literature dating back to the early 1990s reveal an understated role for integrins in gammadeltaTc function. Over the years, integrins have been investigated on resting and/or activated peripheral blood-derived polyclonal gammadeltaTc, gammadeltaTc clones, as well as gammadelta T intraepithelial lymphocytes. Differences in integrin expression have been found between alphabeta T cells (alphabetaTc) and gammadeltaTc, as well as between Vdelta1 and Vdelta2 gammadeltaTc. While most studies have focused on human gammadeltaTc, research has also been carried out in mouse and bovine models. Roles attributed to gammadeltaTc integrins include adhesion, signaling, activation, migration, tissue localization, tissue retention, cell spreading, cytokine secretion, tumor infiltration, and involvement in tumor cell killing. This review attempts to encompass all reports of integrins expressed on gammadeltaTc published prior to December 2017, highlights areas warranting further investigation, and discusses the relevance of integrin expression for gammadeltaTc function. PMID- 29593746 TI - Plasmodium falciparum Liver Stage Infection and Transition to Stable Blood Stage Infection in Liver-Humanized and Blood-Humanized FRGN KO Mice Enables Testing of Blood Stage Inhibitory Antibodies (Reticulocyte-Binding Protein Homolog 5) In Vivo. AB - The invention of liver-humanized mouse models has made it possible to directly study the preerythrocytic stages of Plasmodium falciparum. In contrast, the current models to directly study blood stage infection in vivo are extremely limited. Humanization of the mouse blood stream is achievable by frequent injections of human red blood cells (hRBCs) and is currently the only system with which to study human malaria blood stage infections in a small animal model. Infections have been primarily achieved by direct injection of P. falciparum infected RBCs but as such, this modality of infection does not model the natural route of infection by mosquito bite and lacks the transition of parasites from liver stage infection to blood stage infection. Including these life cycle transition points in a small animal model is of relevance for testing therapeutic interventions. To this end, we used FRGN KO mice that were engrafted with human hepatocytes and performed a blood exchange under immune modulation to engraft the animals with more than 50% hRBCs. These mice were infected by mosquito bite with sporozoite stages of a luciferase-expressing P. falciparum parasite, resulting in noninvasively measurable liver stage burden by in vivo bioluminescent imaging (IVIS) at days 5-7 postinfection. Transition to blood stage infection was observed by IVIS from day 8 onward and then blood stage parasitemia increased with a kinetic similar to that observed in controlled human malaria infection. To assess the utility of this model, we tested whether a monoclonal antibody targeting the erythrocyte invasion ligand reticulocyte-binding protein homolog 5 (with known growth inhibitory activity in vitro) was capable of blocking blood stage infection in vivo when parasites emerge from the liver and found it highly effective. Together, these results show that a combined liver-humanized and blood humanized FRGN mouse model infected with luciferase-expressing P. falciparum will be a useful tool to study P. falciparum preerythrocytic and erythrocytic stages and enables the testing of interventions that target either one or both stages of parasite infection. PMID- 29593747 TI - Whole-Inactivated Influenza Virus Is a Potent Adjuvant for Influenza Peptides Containing CD8+ T Cell Epitopes. AB - Influenza peptide antigens coding for conserved T cell epitopes have the capacity to induce cross-protective influenza-specific immunity. Short peptide antigens used as a vaccine, however, often show poor immunogenicity. In this study, we demonstrate that whole-inactivated influenza virus (WIV) acts as an adjuvant for influenza peptide antigens, as shown by the induction of peptide-specific CD8+ T cells in HLA-A2.1 transgenic mice upon vaccination with the influenza-M1-derived GILGFVFTL peptide (GIL), formulated with WIV. By screening various concentrations of GIL and WIV, we found that both components contributed to the GIL-specific T cell response. Whereas co-localization of the peptide antigen and WIV adjuvant was found to be important, neither physical association between peptide and WIV nor fusogenic activity of WIV were relevant for the adjuvant effect of WIV. We furthermore show that WIV may adjuvate T cell responses to a variety of peptides, using pools of either conserved wild-type influenza peptides or chemically altered peptide ligands. This study shows the potential of WIV as an adjuvant for influenza peptides. The simple formulation process and the solid safety record of WIV make this an attractive adjuvant for T cell peptides, and may also be used for non-influenza antigens. PMID- 29593748 TI - High-Mobility Group Nucleosome-Binding Protein 1 as Endogenous Ligand Induces Innate Immune Tolerance in a TLR4-Sirtuin-1 Dependent Manner in Human Blood Peripheral Mononuclear Cells. AB - High-mobility group nucleosome-binding protein 1 (HMGN1) functions as a non histone chromatin-binding protein in the cell nucleus. However, extracellular HMGN1 acts as an endogenous danger-associated inflammatory mediator (also called alarmin). We demonstrated that HMGN1 not only directly stimulated cytokine production but also had the capacity to induce immune tolerance by a TLR4 dependent pathway, similar to lipopolysaccharide (LPS)-induced tolerance. HMGN1 induced tolerance was accompanied by a metabolic shift associated with the inhibition of the induction of Warburg effect (aerobic glycolysis) and histone deacetylation via Sirtuin-1. In addition, HMGN1 pre-challenge of mice also downregulated TNF production similar to LPS-induced tolerance in vivo. In conclusion, HMGN1 is an endogenous TLR4 ligand that can induce both acute stimulation of cytokine production and long-term tolerance, and thus it might play a modulatory role in sterile inflammatory processes such as those induced by infection, trauma, or ischemia. PMID- 29593750 TI - The Domestication of the Amazon Tree Grape (Pourouma cecropiifolia) Under an Ecological Lens. AB - Domestication studies traditionally focus on the differences in morphological characteristics between wild and domesticated populations that are under direct selection, the components of the domestication syndrome. Here, we consider that other aspects can be modified, because of the interdependence between plant characteristics and the forces of natural selection. We investigated the ongoing domestication of Pourouma cecropiifolia populations cultivated by the Ticuna people in Western Amazonia, using traditional and ecological approaches. We compared fruit characteristics between wild and domesticated populations to quantify the direct effects of domestication. To examine the characteristics that are not under direct selection and the correlated effects of human selection and natural selection, we investigated the differences in vegetative characteristics, changes in seed:fruit allometric relations and the relations of these characteristics with variation in environmental conditions summarized in a principal component analysis. Domestication generated great changes in fruit characteristics, as expected in fruit crops. The fruits of domesticated plants had 20* greater mass and twice as much edible pulp as wild fruits. The plant height:DBH ratio and wood density were, respectively, 42% and 22% smaller in domesticated populations, probably in response to greater luminosity and higher sand content of the cultivated landscapes. Seed:fruit allometry was modified by domestication: although domesticated plants have heavier seeds, the domesticated fruits have proportionally (46%) smaller seed mass compared to wild fruits. The high light availability and poor soils of cultivated landscapes may have contributed to seed mass reduction, while human selection promoted seed mass increase in correlation with fruit mass increase. These contrasting effects generated a proportionately smaller increase in seed mass in domesticated plants. In this study, it was not possible to clearly dissociate the environmental effects from the domestication effects in changes in morphological characteristics, because the environmental conditions were intensively modified by human management, showing that plant domestication is intrinsically related to landscape domestication. Our results suggest that evaluation of environmental conditions together with human selection on domesticated phenotypes provide a better understanding of the changes generated by domestication in plants.

PMID- 29593751 TI - Humic Substances: Determining Potential Molecular Regulatory Processes in Plants. AB - Humic substances (HSs) have considerable effects on soil fertility and crop productivity owing to their unique physiochemical and biochemical properties, and play a vital role in establishing biotic and abiotic interactions within the plant rhizosphere. A comprehensive understanding of the mode of action and tissue distribution of HS is, however, required, as this knowledge could be useful for devising advanced rhizospheric management practices. These substances trigger various molecular processes in plant cells, and can strengthen the plant's tolerance to various kinds of abiotic stresses. HS manifest their effects in cells through genetic, post-transcriptional, and post-translational modifications of signaling entities that trigger different molecular, biochemical, and physiological processes. Understanding of such fundamental mechanisms will provide a better perspective for defining the cues and signaling crosstalk of HS that mediate various metabolic and hormonal networks operating in plant systems. Various regulatory activities and distribution strategies of HS have been discussed in this review. PMID- 29593752 TI - Genetic Dissection of End-Use Quality Traits in Adapted Soft White Winter Wheat. AB - Soft white wheat is used in domestic and foreign markets for various end products requiring specific quality profiles. Phenotyping for end-use quality traits can be costly, time-consuming and destructive in nature, so it is advantageous to use molecular markers to select experimental lines with superior traits. An association mapping panel of 469 soft white winter wheat cultivars and advanced generation breeding lines was developed from regional breeding programs in the U.S. Pacific Northwest. This panel was genotyped on a wheat-specific 90 K iSelect single nucleotide polymorphism (SNP) chip. A total of 15,229 high quality SNPs were selected and combined with best linear unbiased predictions (BLUPs) from historical phenotypic data of the genotypes in the panel. Genome-wide association mapping was conducted using the Fixed and random model Circulating Probability Unification (FarmCPU). A total of 105 significant marker-trait associations were detected across 19 chromosomes. Potentially new loci for total flour yield, lactic acid solvent retention capacity, flour sodium dodecyl sulfate sedimentation and flour swelling volume were also detected. Better understanding of the genetic factors impacting end-use quality enable breeders to more effectively discard poor quality germplasm and increase frequencies of favorable end-use quality alleles in their breeding populations. PMID- 29593753 TI - Ethylene-Related Gene Expression Networks in Wood Formation. AB - Thickening of tree stems is the result of secondary growth, accomplished by the meristematic activity of the vascular cambium. Secondary growth of the stem entails developmental cascades resulting in the formation of secondary phloem outwards and secondary xylem (i.e., wood) inwards of the stem. Signaling and transcriptional reprogramming by the phytohormone ethylene modifies cambial growth and cell differentiation, but the molecular link between ethylene and secondary growth remains unknown. We addressed this shortcoming by analyzing expression profiles and co-expression networks of ethylene pathway genes using the AspWood transcriptome database which covers all stages of secondary growth in aspen (Populus tremula) stems. ACC synthase expression suggests that the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) is synthesized during xylem expansion and xylem cell maturation. Ethylene-mediated transcriptional reprogramming occurs during all stages of secondary growth, as deduced from AspWood expression profiles of ethylene-responsive genes. A network centrality analysis of the AspWood dataset identified EIN3D and 11 ERFs as hubs. No overlap was found between the co-expressed genes of the EIN3 and ERF hubs, suggesting target diversification and hence independent roles for these transcription factor families during normal wood formation. The EIN3D hub was part of a large co expression gene module, which contained 16 transcription factors, among them several new candidates that have not been earlier connected to wood formation and a VND-INTERACTING 2 (VNI2) homolog. We experimentally demonstrated Populus EIN3D function in ethylene signaling in Arabidopsis thaliana. The ERF hubs ERF118 and ERF119 were connected on the basis of their expression pattern and gene co expression module composition to xylem cell expansion and secondary cell wall formation, respectively. We hereby establish data resources for ethylene responsive genes and potential targets for EIN3D and ERF transcription factors in Populus stem tissues, which can help to understand the range of ethylene targeted biological processes during secondary growth. PMID- 29593754 TI - Magnesium Transporter MGT6 Plays an Essential Role in Maintaining Magnesium Homeostasis and Regulating High Magnesium Tolerance in Arabidopsis. AB - Magnesium (Mg) is one of the essential nutrients for all living organisms. Plants acquire Mg from the environment and distribute within their bodies in the ionic form via Mg2+-permeable transporters. In Arabidopsis, the plasma membrane localized magnesium transporter MGT6 mediates Mg2+ uptake under Mg-limited conditions, and therefore is important for the plant adaptation to low-Mg environment. In this study, we further assessed the physiological function of MGT6 using a knockout T-DNA insertional mutant allele. We found that MGT6 was required for normal plant growth during various developmental stages when the environmental Mg2+ was low. Interestingly, in addition to the hypersensitivity to Mg2+ limitation, mgt6 mutants displayed dramatic growth defects when external Mg2+ was in excess. Compared with wild-type plants, mgt6 mutants generally contained less Mg2+ under both low and high external Mg2+ conditions. Reciprocal grafting experiments further underpinned a role of MGT6 in a shoot-based mechanism for detoxifying excessive Mg2+ in the environment. Moreover, we found that mgt6 mgt7 double mutant showed more severe phenotypes compared with single mutants under both low- and high-Mg2+ stress conditions, suggesting that these two MGT-type transporters play an additive role in controlling plant Mg2+ homeostasis under a wide range of external Mg2+ concentrations. PMID- 29593756 TI - Genetics, Host Range, and Molecular and Pathogenic Characterization of Verticillium dahliae From Sunflower Reveal Two Differentiated Groups in Europe. AB - Verticillium wilt and leaf mottle of sunflower, caused by the fungus Verticillium dahliae (Vd) has become a major constraint to sunflower oil production in temperate European countries. Information about Vd from sunflower is very scarce despite genetics, molecular traits and pathogenic abilities of fungal strains affecting many other crops being widely known. Understanding and characterizing the diversity of Vd populations in those countries where sunflowers are frequent and severely affected by the fungus are essential for efficient breeding for resistance. In this study, we have analyzed genetic, molecular and pathogenic traits of Vd isolates affecting sunflower in European countries. When their genetics was investigated, almost all the isolates from France, Italy, Spain, Argentina, and Ukraine were assigned to vegetative compatibility group (VCG) 2B. In Bulgaria, Turkey, Romania, and Ukraine, some isolates were assigned to VCG6, but some others could not be assigned to any VCG. Genotyping markers used for Vd affecting crops other than sunflower showed that all the isolates were molecularly identified as race 2 and that markers of defoliating (D) and non defoliating (ND) pathotypes distinguished two well-differentiated clusters, one (E) grouping those isolates from Eastern Europe and the other (W) all those from the Western Europe and Argentina. All the isolates in cluster W were VCG2B, while the isolates in cluster E belonged to an unknown VCG or to VCG6. When the host range was investigated in the greenhouse, the fungus was highly pathogenic to artichoke, showing the importance of farming alternatives in the management of Verticillium attacks. Sunflower genotypes were inoculated with a selection of isolates in two experiments. Two groups were identified, one including the isolates from Western Europe, Argentina, and Ukraine, and the other including isolates from Bulgaria, Romania, and Turkey. Three pathogenic races were differentiated: V1, V2-EE (Eastern Europe) and V2-WE (Western Europe). Similarly, three differentials are proposed for race identification: HA 458 (universal susceptible), HA 89 (resistant to V2-EE, susceptible to V2-WE) and INRA2603 (susceptible to V2-EE, resistant to V2-WE). The diversity found in Vd affecting sunflower must be taken into account in the search for resistance to the pathogen for European environments of sunflower production. PMID- 29593755 TI - Candidate DNA Barcode Tags Combined With High Resolution Melting (Bar-HRM) Curve Analysis for Authentication of Senna alexandrina Mill. With Validation in Crude Drugs. AB - Senna alexandrina (Fabaceae) is a globally recognized medicinal plant for its laxative properties as well as the only source of sennosides, and is highly exported bulk herb from India. Its major procurement is exclusively from limited cultivation, which leads to risks of deliberate or unintended adulteration. The market raw materials are in powdered or finished product form, which lead to difficulties in authentication. Here, DNA barcode tags based on chloroplast genes (rbcL and matK) and intergenic spacers (psbA-trnH and ITS) were developed for S. alexandrina along with the allied species. The ability and performance of the ITS1 region to discriminate among the Senna species resulted in the present proposal of the ITS1 tags as successful barcode. Further, these tags were coupled with high-resolution melting (HRM) curve analysis in a real-time PCR genotyping method to derive Bar-HRM (Barcoding-HRM) assays. Suitable HRM primer sets were designed through SNP detection and mutation scanning in genomic signatures of Senna species. The melting profiles of S. alexandrina and S. italica subsp. micrantha were almost identical and the remaining five species were clearly separated so that they can be differentiated by HRM method. The sensitivity of the method was utilized to authenticate market samples [Herbal Sample Assays (HSAs)]. HSA01 (S. alexandrina crude drug sample from Bangalore) and HSA06 (S. alexandrina crude drug sample from Tuticorin, Tamil Nadu, India) were found to be highly contaminated with S. italica subsp. micrantha. Species admixture samples mixed in varying percentage was identified sensitively with detection of contamination as low as 1%. The melting profiles of PCR amplicons are clearly distinct, which enables the authentic differentiation of species by the HRM method. This study reveals that DNA barcoding coupled with HRM is an efficient molecular tool to authenticate Senna herbal products in the market for quality control in the drug supply chain.

AB - Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming the most damaging and economically important disease of this crop. The identification and characterization of genes that regulate infection processes and pathogenicity in P. fijiensis will provide important knowledge for the development of disease resistant cultivars. In many fungal plant pathogens, the Fus3 and Slt2 are reported to be essential for pathogenicity. Fus3 regulates filamentous-invasion pathways including the formation of infection structures, sporulation, virulence, and invasive and filamentous growth, whereas Slt2 is involved in the cell-wall integrity pathway, virulence, invasive growth, and colonization in host tissues. Here, we used RNAi-mediated gene silencing to investigate the role of the Slt2 and Fus3 homologs in P. fijiensis in pathogen invasiveness, growth and pathogenicity. The PfSlt2 and PfFus3 silenced P. fijiensis transformants showed significantly lower gene expression and reduced virulence, invasive growth, and lower biomass in infected leaf tissues of East African Highland Banana (EAHB). This study suggests that Slt2 and Fus3 MAPK signaling pathways play important roles in plant infection and pathogenic growth of fungal pathogens. The silencing of these vital fungal genes through host-induced gene silencing (HIG) could be an alternative strategy for developing transgenic banana and plantain resistant to BSD.

AB - Induction and secretion of acid phosphatases (APases) is considered to be an important strategy for improving plant growth under conditions of low inorganic phosphate (Pi). Purple acid phosphatases (PAPs), are an important class of plant APases that could be secreted into the rhizosphere to utilize organic phosphorus (Po) for plant growth and development. To date, only a few members of the PAP family have been identified in soybean. In this paper, we identified a secreted PAP in soybean, GmPAP14, and investigated its role in utilizing external phytate, the main form of organic phosphorus in the soil. An analysis of its expression and promoter showed that GmPAP14 was mainly expressed in the root and was strongly induced following Po treatment, during which its expression expanded from meristematic to maturation zones and root hairs. In vitro enzyme assays indicated that GmPAP14 had a relatively high phytase activity. Furthermore, GmPAP14 overexpression increased secreted APase activities and phytase activities, leading to the improved use of external plant phytate, higher phosphorus content, and increased shoot weight. Thus, these results confirmed that GmPAP14 is an important gene induced in response to Po, and that it predominantly participates in utilizing external Po to enhance plant growth and development. PMID- 29593759 TI - Nutrient Characteristics in Relation to Plant Size of a Perennial Grass Under Grazing Exclusion in Degraded Grassland. AB - Identifying the linkages between nutrient properties and plant size is important for reducing uncertainty in understanding the mechanisms of plant phenotypic plasticity. Although the positive effects of grazing exclusion on plant morphological plasticity has been well documented, surprisingly little is known about the relationship of nutrient strategies with plant shoot size after long term grazing exclusion. We experimentally investigated the impacts of grazing exclusion over time (0, 9, 15, and 35 years) on the relationships of nutrient traits (nutrient concentration, allocation, and stoichiometry) of with morphological plasticity in Leymus chinensis, which is a dominant species in grasslands of Inner Mongolia, China. Our results showed that there was a significantly negative correlation between the degrees of plasticity and stability of various morphological traits. Increases in plant size by 126.41, 164.17, and 247.47% were observed with the increase of grazing exclusion time of 9, 15, and 35 years, respectively. Plant size was negatively correlated with nitrogen (N) and phosphorus (P) concentrations, but was positively correlated with carbon (C) concentration. Biomass partitioning and leaf to stem ratios of nutrient concentrations contributed more than 95% of the changes in N, P, and C allocation in L. chinensis leaves and stems induced by grazing exclusions. Nine years' grazing exclusion rapidly changed the nutrient concentrations (averaged by -34.84%), leaf to stem nutrient allocations (averaged by -86.75%), and ecological stoichiometry (averaged by +46.54%) compared to free-grazing, whereas there was no significant trend of these nutrient traits across the 9, 15, and 35 years' grazing exclusion in L. chinensis individuals. Our findings suggest that with the increase of the duration of the grazing exclusion, time effects on plant performances gradually weakened both in plant morphological plasticity and nutrient properties. There is a significant negative effect between plant sizes and nutrient traits under long-term grazing exclusion. PMID- 29593760 TI - Nitric Oxide Enables Germination by a Four-Pronged Attack on ABA-Induced Seed Dormancy. AB - Nitric oxide (?NO) is known to attenuate dormancy and promote germination, a function that seemingly depends on crosstalk with the abscisic acid (ABA) signaling network. In the past 2 years, a number of independent studies have revealed that ?NO gates the ABA signaling network at multiple steps, ensuring redundant and effectively irreversible control of germination. Here we summarize the recent studies, and propose a model of the multiple functions of ?NO in seed dormancy. PMID- 29593761 TI - 14-3-3 Proteins in Plant Hormone Signaling: Doing Several Things at Once. AB - In this review we highlight the advances achieved in the investigation of the role of 14-3-3 proteins in hormone signaling, biosynthesis, and transport. 14-3-3 proteins are a family of conserved molecules that target a number of protein clients through their ability to recognize well-defined phosphorylated motifs. As a result, they regulate several cellular processes, ranging from metabolism to transport, growth, development, and stress response. High-throughput proteomic data and two-hybrid screen demonstrate that 14-3-3 proteins physically interact with many protein clients involved in the biosynthesis or signaling pathways of the main plant hormones, while increasing functional evidence indicates that 14-3 3-target interactions play pivotal regulatory roles. These advances provide a framework of our understanding of plant hormone action, suggesting that 14-3-3 proteins act as hubs of a cellular web encompassing different signaling pathways, transducing and integrating diverse hormone signals in the regulation of physiological processes. PMID- 29593762 TI - Overexpression of the Maize Sulfite Oxidase Increases Sulfate and GSH Levels and Enhances Drought Tolerance in Transgenic Tobacco. AB - Sulfite oxidase (SO) plays a pivotal role in sulfite metabolism. In our previous study, sulfite-oxidizing function of the SO from Zea mays (ZmSO) was characterized. To date, the knowledge of ZmSO's involvement in abiotic stress response is scarce. In this study, we aimed to investigate the role of ZmSO in drought stress. The transcript levels of ZmSO were relatively high in leaves and immature embryos of maize plants, and were up-regulated markedly by PEG-induced water stress. Overexpression of ZmSO improved drought tolerance in tobacco. ZmSO overexpressing transgenic plants showed higher sulfate and glutathione (GSH) levels but lower hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents under drought stress, indicating that ZmSO confers drought tolerance by enhancing GSH-dependent antioxidant system that scavenged ROS and reduced membrane injury. In addition, the transgenic plants exhibited more increased stomatal response than the wild-type (WT) to water deficit. Interestingly, application of exogenous GSH effectively alleviated growth inhibition in both WT and transgenic plants under drought conditions. qPCR analysis revealed that the expression of several sulfur metabolism-related genes was significantly elevated in the ZmSO overexpressing lines. Taken together, these results imply that ZmSO confers enhanced drought tolerance in transgenic tobacco plants possibly through affecting stomatal regulation, GSH-dependent antioxidant system, and sulfur metabolism-related gene expression. ZmSO could be exploited for developing drought-tolerant maize varieties in molecular breeding. PMID- 29593763 TI - Identification and Expression Analysis of Medicago truncatula Isopentenyl Transferase Genes (IPTs) Involved in Local and Systemic Control of Nodulation. AB - Cytokinins are essential for legume plants to establish a nitrogen-fixing symbiosis with rhizobia. Recently, the expression level of cytokinin biosynthesis IPTs (ISOPENTENYLTRANSFERASES) genes was shown to be increased in response to rhizobial inoculation in Lotus japonicus, Medicago truncatula and Pisum sativum. In addition to its well-established positive role in nodule primordium initiation in root cortex, cytokinin negatively regulates infection processes in the epidermis. Moreover, it was reported that shoot-derived cytokinin inhibits the subsequent nodule formation through AON (autoregulation of nodulation) pathway. In L. japonicus, LjIPT3 gene was shown to be activated in the shoot phloem via the components of AON system, negatively affecting nodulation. However, in M. truncatula, the detailed analysis of MtIPTs expression, both in roots and shoots, in response to nodulation has not been performed yet, and the link between IPTs and AON has not been studied so far. In this study, we performed an extensive analysis of MtIPTs expression levels in different organs, focusing on the possible role of MtIPTs in nodule development. MtIPTs expression dynamics in inoculated roots suggest that besides its early established role in the nodule primordia development, cytokinin may be also important for later stages of nodulation. According to expression analysis, MtIPT3, MtIPT4, and MtIPT5 are activated in the shoots in response to inoculation. Among these genes, MtIPT3 is the only one the induction of which was not observed in leaves of the sunn-3 mutant defective in CLV1-like kinase, the key component of AON, suggesting that MtIPT3 is activated in the shoots in an AON-dependent manner. Taken together, our findings suggest that MtIPTs are involved in the nodule development at different stages, both locally in inoculated roots and systemically in shoots, where their expression can be activated in an AON-dependent manner. PMID- 29593764 TI - Genetic Dissection and Simultaneous Improvement of Drought and Low Nitrogen Tolerances by Designed QTL Pyramiding in Rice. AB - Drought and low nitrogen are the most common abiotic stresses limiting rice productivity in the rainfed rice areas of Asia and Africa. Development and adoption of green super rice (GSR) varieties with greatly improved drought tolerance (DT) and low nitrogen tolerance (LNT) are the most efficient way to resolve this problem. In this study, using three sets of trait-specific introgression lines (ILs) in a Xian (indica) variety Huanghuazhan (HHZ) background, we identified nine DT-QTL and seven LNT-QTL by a segregation distortion approach and a genome-wide association study, respectively. Based on performances of DT and LNT and genotypes at the detected QTL, two ILs M79 and M387 with DT and LNT were selected for cross-making to validate the identified QTL and to develop DT and LNT rice lines by pyramiding two DT-QTL (qDT3.9 and qDT6.3) and two LNT-QTL (qGY1 and qSF8). Using four pairs of kompetitive allele specific PCR (KASP) SNP markers, we selected 66 F2 individuals with different combinations of the target DT- and LNT-QTL favorable alleles and they showed expected improvement in DT and/or LNT, which were further validated by the significant improvement in DT and/or LNT of their F3 progeny testing. Based on evaluation of pyramiding lines in F3 lines under drought, low nitrogen (LN) and normal conditions, four promising pyramiding lines having different QTL favorable alleles were selected, which showed significantly improved tolerances to drought and/or LN than HHZ and their IL parents. Our results demonstrated that trait specific ILs could effectively connect QTL mapping and QTL pyramiding breeding, and designed QTL pyramiding (DQP) using ILs could be more effective in molecular rice breeding for complex quantitative traits. PMID- 29593765 TI - Zinc and Iron Concentration as Affected by Nitrogen Fertilization and Their Localization in Wheat Grain. AB - Nearly half of the world cereal production comes from soils low or marginal in plant available zinc, leading to unsustainable and poor quality grain production. Therefore, the effects of nitrogen (N) rate and application time on zinc (Zn) and iron (Fe) concentration in wheat grain were investigated. Wheat (Triticum aestivum var. Krabat) was grown in a growth chamber with 8 and 16 h of day and night periods, respectively. The N rates were 29, 43, and 57 mg N kg-1 soil, equivalent to 80, 120, and 160 kg N ha-1. Zinc and Fe were applied at 10 mg kg-1 growth media. In one of the N treatments, additional Zn and Fe through foliar spray (6 mg of Zn or Fe in 10 ml water/pot) was applied. Micro-analytical localization of Zn and Fe within grain was performed using scanning macro-X-ray fluorescence (MA-XRF) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). The following data were obtained: grain and straw yield pot-1, 1000 grains weight, number of grains pot-1, whole grain protein content, concentration of Zn and Fe in the grains. Grain yield increased from 80 to 120 kg N ha-1 rates only and decreased at 160 kg N ha-1 g. Relatively higher protein content and Zn and Fe concentration in the grain were recorded with the split N application of 160 kg N ha-1. Soil and foliar supply of Zn and Fe (Zn + Fes+f), with a single application of 120 kg N ha-1N at sowing, increased the concentration of Zn by 46% and of Fe by 35%, as compared to their growth media application only. Line scans of freshly cut areas of sliced grains showed co localization of Zn and Fe within germ, crease and aleurone. We thus conclude that split application of N at 160 kg ha-1 at sowing and stem elongation, in combination with soil and foliar application of Zn and Fe, can be a good agricultural practice to enhance protein content and the Zn and Fe concentration in grain. PMID- 29593766 TI - Overexpression of OsNAC14 Improves Drought Tolerance in Rice. AB - Plants have evolved to have sophisticated adaptation mechanisms to cope with drought stress by reprograming transcriptional networks through drought responsive transcription factors. NAM, ATAF1-2, and CUC2 (NAC) transcription factors are known to be associated with various developmental processes and stress tolerance. In this study, we functionally characterized the rice drought responsive transcription factor OsNAC14. OsNAC14 was predominantly expressed at meiosis stage but is induced by drought, high salinity, ABA, and low temperature in leaves. Overexpression of OsNAC14 resulted in drought tolerance at the vegetative stage of growth. Field drought tests demonstrated that OsNAC14 overexpressing transgenic rice lines exhibited higher number of panicle and filling rate compared to non-transgenic plants under drought conditions. RNA sequencing analysis revealed that OsNAC14 overexpression elevated the expression of genes for stress response, DNA damage repair, defense related, and strigolactone biosynthesis. In addition, chromatin immunoprecipitation analysis confirmed the direct interaction of OsNAC14 with the promoter of OsRAD51A1, a key component in homologous recombination in DNA repair system. Collectively, these results indicate that OsNAC14 mediates drought tolerance by recruiting factors involved in DNA damage repair and defense response resulting in improved tolerance to drought. PMID- 29593767 TI - mRNA Decapping and 5'-3' Decay Contribute to the Regulation of ABA Signaling in Arabidopsis thaliana. AB - Defects in RNA processing and degradation pathways often lead to developmental abnormalities, impaired hormonal signaling and altered resistance to abiotic and biotic stress. Here we report that components of the 5'-3' mRNA decay pathway, DCP5, LSM1-7 and XRN4, contribute to a proper response to a key plant hormone abscisc acid (ABA), albeit in a different manner. Plants lacking DCP5 are more sensitive to ABA during germination, whereas lsm1a lsm1b and xrn4-5 mutants are affected at the early stages of vegetative growth. In addition, we show that DCP5 and LSM1 regulate mRNA stability and act in translational repression of the main components of the early ABA signaling, PYR/PYL ABA receptors and SnRK2s protein kinases. mRNA decapping DCP and LSM1-7 complexes also appear to modulate ABA dependent expression of stress related transcription factors from the AP2/ERF/DREB family that in turn affect the level of genes regulated by the PYL/PYR/RCAR-PP2C-SnRK2 pathway. These observations suggest that ABA signaling through PYL/PYR/RCAR receptors and SnRK2s kinases is regulated directly and indirectly by the cytoplasmic mRNA decay pathway. PMID- 29593768 TI - Genetic and Molecular Mechanisms Underlying Symbiotic Specificity in Legume Rhizobium Interactions. AB - Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant. Establishment of a successful symbiosis requires the two symbiotic partners to be compatible with each other throughout the process of symbiotic development. However, incompatibility frequently occurs, such that a bacterial strain is unable to nodulate a particular host plant or forms nodules that are incapable of fixing nitrogen. Genetic and molecular mechanisms that regulate symbiotic specificity are diverse, involving a wide range of host and bacterial genes/signals with various modes of action. In this review, we will provide an update on our current knowledge of how the recognition specificity has evolved in the context of symbiosis signaling and plant immunity. PMID- 29593769 TI - Genetic Loci Conferring Reducing Sugar Accumulation and Conversion of Cold-Stored Potato Tubers Revealed by QTL Analysis in a Diploid Population. AB - Cold-induced sweetening (CIS) caused by reducing sugar (RS) accumulation during storage in low temperature in potato tubers is a critical factor influencing the quality of fried potato products. The reconditioning (REC) by arising storage temperature is a common measure to lower down RS. However, both CIS and REC are genotype-dependent and the genetic basis remains uncertain. In the present study, with a diploid potato population with broad genetic background, four reproducible QTL of CIS and two of REC were resolved on chromosomes 5, 6, and 7 of the CIS sensitive parent and chromosomes 5 and 11 of the CIS-resistant parent, respectively, implying that these two traits may be genetically independent. This hypothesis was also supported by the colocalization of two functional genes, a starch synthesis gene AGPS2 mapped in QTL CIS_E_07-1 and a starch hydrolysis gene GWD colocated with QTL REC_B_05-1. The cumulative effects of identified QTL were proved to contribute largely and stably to CIS and REC and confirmed with a natural population composed of a range of cultivars and breeding lines. The present research identified reproducible QTL for CIS and REC of potato in diverse conditions and elucidated for the first time their cumulative genetic effects, which provides theoretical bases and applicable means for tuber quality improvement.

PMID- 29593770 TI - The Glycerate and Phosphorylated Pathways of Serine Synthesis in Plants: The Branches of Plant Glycolysis Linking Carbon and Nitrogen Metabolism. AB - Serine metabolism in plants has been studied mostly in relation to photorespiration where serine is formed from two molecules of glycine. However, two other pathways of serine formation operate in plants and represent the branches of glycolysis diverging at the level of 3-phosphoglyceric acid. One branch (the glycerate - serine pathway) is initiated in the cytosol and involves glycerate formation from 3-phosphoglycerate, while the other (the phosphorylated serine pathway) operates in plastids and forms phosphohydroxypyruvate as an intermediate. Serine formed in these pathways becomes a precursor of glycine, formate and glycolate accumulating in stress conditions. The pathways can be linked to GABA shunt via transamination reactions and via participation of the same reductase for both glyoxylate and succinic semialdehyde. In this review paper we present a hypothesis of the regulation of redox balance in stressed plant cells via participation of the reactions associated with glycerate and phosphorylated serine pathways. We consider these pathways as important processes linking carbon and nitrogen metabolism and maintaining cellular redox and energy levels in stress conditions. PMID- 29593772 TI - Genetic and Developmental Basis for Increased Leaf Thickness in the Arabidopsis Cvi Ecotype. AB - Leaf thickness is a quantitative trait that is associated with the ability of plants to occupy dry, high irradiance environments. Despite its importance, leaf thickness has been difficult to measure reproducibly, which has impeded progress in understanding its genetic basis, and the associated anatomical mechanisms that pattern it. Here, we used a custom-built dual confocal profilometer device to measure leaf thickness in the Arabidopsis Ler * Cvi recombinant inbred line population and found statistical support for four quantitative trait loci (QTL) associated with this trait. We used publically available data for a suite of traits relating to flowering time and growth responses to light quality and show that three of the four leaf thickness QTL coincide with QTL for at least one of these traits. Using time course photography, we quantified the relative growth rate and the pace of rosette leaf initiation in the Ler and Cvi ecotypes. We found that Cvi rosettes grow slower than Ler, both in terms of the rate of leaf initiation and the overall rate of biomass accumulation. Collectively, these data suggest that leaf thickness is tightly linked with physiological status and may present a tradeoff between the ability to withstand stress and rapid vegetative growth. To understand the anatomical basis of leaf thickness, we compared cross sections of Cvi and Ler leaves and show that Cvi palisade mesophyll cells elongate anisotropically contributing to leaf thickness. Flow cytometry of whole leaves show that endopolyploidy accompanies thicker leaves in Cvi. Overall, our data suggest that mechanistically, an altered schedule of cellular events affecting endopolyploidy and increasing palisade mesophyll cell length contribute to increase of leaf thickness in Cvi. Ultimately, knowledge of the genetic basis and developmental trajectory leaf thickness will inform the mechanisms by which natural selection acts to produce variation in this adaptive trait. PMID- 29593773 TI - Sequencing and Analysis of Strobilanthes cusia (Nees) Kuntze Chloroplast Genome Revealed the Rare Simultaneous Contraction and Expansion of the Inverted Repeat Region in Angiosperm. AB - Ban-Lan-Gen, the root tissues derived from several morphologically indistinguishable plant species, have been used widely in traditional Chinese medicines for numerous years. The identification of reliable markers to distinguish various source plant species is critical for the effective and safe use of products containing Ban-Lan-Gen. Here, we analyzed and characterized the complete chloroplast (cp) genome sequence of Strobilanthes cusia (Nees) Kuntze to identify high-resolution markers for the species determination of Southern Ban Lan-Gen. Total DNA was extracted and subjected to next-generation sequencing. The cp genome was then assembled, and the gaps were filled using PCR amplification and Sanger sequencing. Genome annotation was conducted using CpGAVAS web server. The genome was 144,133 bp in length, presenting a typical quadripartite structure of large (LSC; 91,666 bp) and small (SSC; 17,328 bp) single-copy regions separated by a pair of inverted repeats (IRs; 17,811 bp). The genome encodes 113 unique genes, including 79 protein-coding, 30 transfer RNA, and 4 ribosomal RNA genes. A total of 20 tandem, 2 forward, and 6 palindromic repeats were detected in the genome. A phylogenetic analysis based on 65 protein-coding genes showed that S. cusia was closely related to Andrographis paniculata and Ruellia breedlovei, which belong to the same family, Acanthaceae. One interesting feature is that the IR regions apparently undergo simultaneous contraction and expansion, resulting in the presence of single copies of rps19, rpl2, rpl23, and ycf2 in the LSC region and the duplication of psbA and trnH genes in the IRs. This study provides the first complete cp genome in the genus Strobilanthes, containing critical information for the classification of various Strobilanthes species in the future. This study also provides the foundation for precisely determining the plant sources of Ban-Lan-Gen. PMID- 29593774 TI - The Role of Hydrogen Peroxide in Mediating the Mechanical Wounding-Induced Freezing Tolerance in Wheat. AB - Systemic wound response (SWR), a well-characterized systemic signaling response, plays crucial roles in plant defense responses. Progress in understanding of the SWR in abiotic stress has also been aided by the researchers. However, the function of SWR in freezing stress remains elusive. In this study, we showed that local mild mechanical wounding enhanced freezing tolerance in newly occurred systemic leaves of wheat plants (Triticum aestivum L.). Wounding significantly increased the maximal photochemical efficiency of photosystem II, net photosynthetic rate, and the activities of the antioxidant enzymes under freezing stress. Wounding also alleviated freezing-induced chlorophyll decomposition, electrolyte leakage, water lose, and membrane peroxidation. In addition, wounding induced freezing stress mitigation was closely associated with the ratio between reduced glutathione (GSH) and oxidized glutathione (GSSG), and the ratio between ascorbate (AsA) and dehydroascorbate (DHA), as well as the contents of total soluble sugars and free amino acids. Importantly, pharmacological study showed that wounding-induced freezing tolerance was substantially arrested by pretreatment of wheat leaves with the scavenger of hydrogen peroxide (H2O2) or the inhibitor of NADPH oxidase (RBOH). These results support the hypothesis that local mechanical wounding-induced SWR in newly occurred leaves is largely attributed to RBOH-dependent H2O2 production, which may subsequently induce freezing tolerance in wheat plants. This mechanism may have a potential application to reduce the yield losses of wheat under late spring freezing conditions. Highlights: In our previous research, we found that local mechanical wounding could induce freezing tolerance in the upper systemic leaves of wheat plants. Surprisingly, in this paper, we further demonstrated that local mechanical wounding could also increase freezing resistance in newly occurred leaves of wheat plants. RBOH mediated H2O2 and ascorbate-glutathione cycle participate in this systemic wound response. PMID- 29593775 TI - Evaluation of the Relationship between the Serum Alkaline Phosphatase Level at Dialysis Initiation and All-Cause Mortality: A Multicenter, Prospective Study. AB - Background/Aim: High serum alkaline phosphatase (ALP) levels predict mortality independent of bone metabolism parameters and liver function test results in patients on hemodialysis. The relationship between serum ALP at dialysis initiation and mortality during maintenance dialysis is unknown; therefore, we aimed to identify an association. Methods: This multicenter, prospective cohort study analyzed 1,213 patients registered in the Aichi Cohort Study of Prognosis in Patients Newly Initiated into Dialysis from October 2011 to September 2013. Patients were divided into 2 groups based on serum ALP levels. All-cause mortality and incidences of cardiovascular events after dialysis initiation were compared using the log-rank test and multivariate Cox proportional hazard regression analysis. We performed stratified analysis based on parathyroid hormone (PTH) levels. Results: During the follow-up, 109 (18.0%) and 86 (14.1%) patients died in the high ALP group (232 >=IU/L; High ALP group) and low ALP group (232 =300 pg/mL) PTH level (p = 1.000). Conclusion: The serum ALP level at dialysis initiation is associated with all-cause mortality during maintenance dialysis. PMID- 29593776 TI - Navigating the Interface Between Landscape Genetics and Landscape Genomics. AB - As next-generation sequencing data become increasingly available for non-model organisms, a shift has occurred in the focus of studies of the geographic distribution of genetic variation. Whereas landscape genetics studies primarily focus on testing the effects of landscape variables on gene flow and genetic population structure, landscape genomics studies focus on detecting candidate genes under selection that indicate possible local adaptation. Navigating the transition between landscape genomics and landscape genetics can be challenging. The number of molecular markers analyzed has shifted from what used to be a few dozen loci to thousands of loci and even full genomes. Although genome scale data can be separated into sets of neutral loci for analyses of gene flow and population structure and putative loci under selection for inference of local adaptation, there are inherent differences in the questions that are addressed in the two study frameworks. We discuss these differences and their implications for study design, marker choice and downstream analysis methods. Similar to the rapid proliferation of analysis methods in the early development of landscape genetics, new analytical methods for detection of selection in landscape genomics studies are burgeoning. We focus on genome scan methods for detection of selection, and in particular, outlier differentiation methods and genetic-environment association tests because they are the most widely used. Use of genome scan methods requires an understanding of the potential mismatches between the biology of a species and assumptions inherent in analytical methods used, which can lead to high false positive rates of detected loci under selection. Key to choosing appropriate genome scan methods is an understanding of the underlying demographic structure of study populations, and such data can be obtained using neutral loci from the generated genome-wide data or prior knowledge of a species' phylogeographic history. To this end, we summarize recent simulation studies that test the power and accuracy of genome scan methods under a variety of demographic scenarios and sampling designs. We conclude with a discussion of additional considerations for future method development, and a summary of methods that show promise for landscape genomics studies but are not yet widely used. PMID- 29593777 TI - High-Throughput Sequencing Strategy for Microsatellite Genotyping Using Neotropical Fish as a Model. AB - Genetic diversity and population studies are essential for conservation and wildlife management programs. However, monitoring requires the analysis of multiple loci from many samples. These processes can be laborious and expensive. The choice of microsatellites and PCR calibration for genotyping are particularly daunting. Here we optimized a low-cost genotyping method using multiple microsatellite loci for simultaneous genotyping of up to 384 samples using next generation sequencing (NGS). We designed primers with adapters to the combinatorial barcoding amplicon library and sequenced samples by MiSeq. Next, we adapted a bioinformatics pipeline for genotyping microsatellites based on read length and sequence content. Using primer pairs for eight microsatellite loci from the fish Prochilodus costatus, we amplified, sequenced, and analyzed the DNA of 96, 288, or 384 individuals for allele detection. The most cost-effective methodology was a pseudo-multiplex reaction using a low-throughput kit of 1 M reads (Nano) for 384 DNA samples. We observed an average of 325 reads per individual per locus when genotyping eight loci. Assuming a minimum requirement of 10 reads per loci, two to four times more loci could be tested in each run, depending on the quality of the PCR reaction of each locus. In conclusion, we present a novel method for microsatellite genotyping using Illumina combinatorial barcoding that dispenses exhaustive PCR calibrations, since non-specific amplicons can be eliminated by bioinformatics analyses. This methodology rapidly provides genotyping data and is therefore a promising development for large-scale conservation-genetics studies. PMID- 29593779 TI - Genetic Diversity and Population Structure of F3:6 Nebraska Winter Wheat Genotypes Using Genotyping-By-Sequencing. AB - The availability of information on the genetic diversity and population structure in wheat (Triticum aestivum L.) breeding lines will help wheat breeders to better use their genetic resources and manage genetic variation in their breeding program. The recent advances in sequencing technology provide the opportunity to identify tens or hundreds of thousands of single nucleotide polymorphism (SNPs) in large genome species (e.g., wheat). These SNPs can be utilized for understanding genetic diversity and performing genome wide association studies (GWAS) for complex traits. In this study, the genetic diversity and population structure were investigated in a set of 230 genotypes (F3:6) derived from various crosses as a prerequisite for GWAS and genomic selection. Genotyping-by sequencing provided 25,566 high-quality SNPs. The polymorphism information content (PIC) across chromosomes ranged from 0.09 to 0.37 with an average of 0.23. The distribution of SNPs markers on the 21 chromosomes ranged from 319 on chromosome 3D to 2,370 on chromosome 3B. The analysis of population structure revealed three subpopulations (G1, G2, and G3). Analysis of molecular variance identified 8% variance among and 92% within subpopulations. Of the three subpopulations, G2 had the highest level of genetic diversity based on three genetic diversity indices: Shannon's information index (I) = 0.494, diversity index (h) = 0.328 and unbiased diversity index (uh) = 0.331, while G3 had lowest level of genetic diversity (I = 0.348, h = 0.226 and uh = 0.236). This high genetic diversity identified among the subpopulations can be used to develop new wheat cultivars. PMID- 29593778 TI - Evaluation of Reference Genes to Analyze Gene Expression in Silverside Odontesthes humensis Under Different Environmental Conditions. AB - Some mammalian reference genes, which are widely used to normalize the qRT-PCR, could not be used for this purpose due to its high expression variation. The normalization with false reference genes leads to misinterpretation of results. The silversides (Odontesthes spp.) has been used as models for evolutionary, osmoregulatory and environmental pollution studies but, up to now, there are no studies about reference genes in any Odontesthes species. Furthermore, many studies on silversides have used reference genes without previous validations. Thus, present study aimed to was to clone and sequence potential reference genes, thereby identifying the best ones in Odontesthes humensis considering different tissues, ages and conditions. For this purpose, animals belonging to three ages (adults, juveniles, and immature) were exposed to control, Roundup(r), and seawater treatments for 24 h. Blood samples were subjected to flow-cytometry and other collected tissues to RNA extraction; cDNA synthesis; molecular cloning; DNA sequencing; and qRT-PCR. The candidate genes tested included 18s, actb, ef1a, eif3g, gapdh, h3a, atp1a, and tuba. Gene expression results were analyzed using five algorithms that ranked the candidate genes. The flow-cytometry data showed that the environmental challenges could trigger a systemic response in the treated fish. Even during this systemic physiological disorder, the consensus analysis of gene expression revealed h3a to be the most stable gene expression when only the treatments were considered. On the other hand, tuba was the least stable gene in the control and gapdh was the least stable in both Roundup(r) and seawater groups. In conclusion, the consensus analyses of different tissues, ages, and treatments groups revealed that h3a is the most stable gene whereas gapdh and tuba are the least stable genes, even being considered two constitutive genes. PMID- 29593780 TI - Accuracy of Genomic Evaluations of Juvenile Growth Rate in Common Carp (Cyprinus carpio) Using Genotyping by Sequencing. AB - Cyprinids are the most important group of farmed fish globally in terms of production volume, with common carp (Cyprinus carpio) being one of the most valuable species of the group. The use of modern selective breeding methods in carp is at a formative stage, implying a large scope for genetic improvement of key production traits. In the current study, a population of 1,425 carp juveniles, originating from a partial factorial cross between 40 sires and 20 dams, was used for investigating the potential of genomic selection (GS) for juvenile growth, an exemplar polygenic production trait. RAD sequencing was used to identify and genotype SNP markers for subsequent parentage assignment, construction of a medium density genetic map (12,311 SNPs), genome-wide association study (GWAS), and testing of GS. A moderate heritability was estimated for body length of carp at 120 days (as a proxy of juvenile growth) of 0.33 (s.e. 0.05). No genome-wide significant QTL was identified using a single marker GWAS approach. Genomic prediction of breeding values outperformed pedigree based prediction, resulting in 18% improvement in prediction accuracy. The impact of reduced SNP densities on prediction accuracy was tested by varying minor allele frequency (MAF) thresholds, with no drop in prediction accuracy until the MAF threshold is set <0.3 (2,744 SNPs). These results point to the potential for GS to improve economically important traits in common carp breeding programs. PMID- 29593781 TI - Incidentalome in Neurogenetics: Pathogenic Variant of NSD1 in a Patient With Spinocerebellar Ataxia (SCA). AB - Background: Genetic studies of late-onset sporadic ataxias (>40 years of age) are not routinely indicated. For unresolved cases, next-generation sequencing (NGS) tools, such as whole-exome sequencing (WES), are available for a definitive diagnosis. Case presentation: Our patient is a woman with a usual facial phenotype and anthropometry, who developed ataxia at 45 years of age, with no relevant family history and an initial clinical approach that ruled out common aetiologies. WES was performed when the patient was 54 years old. The results identified the heterozygous pathogenic variant c.248delA (p.N83MfsX4) in the nuclear receptor-binding SET domain protein 1 (NSD1; MIM 606681) gene (related to Sotos syndrome), which was not associated with ataxia and is not related to the patient's phenotype. Sanger sequencing of NSD1 in two different laboratories confirmed the variant. Conclusions: NGS findings generally offer valuable information that can be used for clinical decision-making. However, an incidental finding that leads to defining new clinical and bioethical actions is also possible. Consequently, the biological importance of this type of genetic "incidentalome" must be determined. PMID- 29593782 TI - Bilateral Transcranial Direct Current Stimulation Reshapes Resting-State Brain Networks: A Magnetoencephalography Assessment. AB - Transcranial direct current stimulation (tDCS) can noninvasively induce brain plasticity, and it is potentially useful to treat patients affected by neurological conditions. However, little is known about tDCS effects on resting state brain networks, which are largely involved in brain physiological functions and in diseases. In this randomized, sham-controlled, double-blind study on healthy subjects, we have assessed the effect of bilateral tDCS applied over the sensorimotor cortices on brain and network activity using a whole-head magnetoencephalography system. Bilateral tDCS, with the cathode (-) centered over C4 and the anode (+) centered over C3, reshapes brain networks in a nonfocal fashion. Compared to sham stimulation, tDCS reduces left frontal alpha, beta, and gamma power and increases global connectivity, especially in delta, alpha, beta, and gamma frequencies. The increase of connectivity is consistent across bands and widespread. These results shed new light on the effects of tDCS and may be of help in personalizing treatments in neurological disorders. PMID- 29593783 TI - Perinatal Programming of Circadian Clock-Stress Crosstalk. AB - An intact communication between circadian clocks and the stress system is important for maintaining physiological homeostasis under resting conditions and in response to external stimuli. There is accumulating evidence for a reciprocal interaction between both-from the systemic to the molecular level. Disruption of this interaction by external factors such as shiftwork, jetlag, or chronic stress increases the risk of developing metabolic, immune, or mood disorders. From experiments in rodents, we know that both systems maturate during the perinatal period. During that time, exogenous factors such as stress or alterations in the external photoperiod may critically affect-or program-physiological functions later in life. This developmental programming process has been attributed to maternal stress signals reaching the embryo, which lastingly change gene expression through the induction of epigenetic mechanisms. Despite the well-known function of the adult circadian system in temporal coordination of physiology and behavior, the role of maternal and embryonic circadian clocks during pregnancy and postnatal development is still poorly defined. A better understanding of the circadian-stress crosstalk at different periods of development may help to improve stress resistance and devise preventive and therapeutic strategies against chronic stress-associated disorders. PMID- 29593784 TI - Precision Light for the Treatment of Psychiatric Disorders. AB - Circadian timekeeping can be reset by brief flashes of light using stimulation protocols thousands of times shorter than those previously assumed to be necessary for traditional phototherapy. These observations point to a future where flexible architectures of nanosecond-, microsecond-, and millisecond-scale light pulses are compiled to reprogram the brain's internal clock when it has been altered by psychiatric illness or advanced age. In the current review, we present a chronology of seminal experiments that established the synchronizing influence of light on the human circadian system and the efficacy of prolonged bright-light exposure for reducing symptoms associated with seasonal affective disorder. We conclude with a discussion of the different ways that precision flashes could be parlayed during sleep to effect neuroadaptive changes in brain function. This article is a contribution to a special issue on Circadian Rhythms in Regulation of Brain Processes and Role in Psychiatric Disorders curated by editors Shimon Amir, Karen Gamble, Oliver Stork, and Harry Pantazopoulos. PMID- 29593786 TI - Acoustic Trauma Changes the Parvalbumin-Positive Neurons in Rat Auditory Cortex. AB - Acoustic trauma is being reported to damage the auditory periphery and central system, and the compromised cortical inhibition is involved in auditory disorders, such as hyperacusis and tinnitus. Parvalbumin-containing neurons (PV neurons), a subset of GABAergic neurons, greatly shape and synchronize neural network activities. However, the change of PV neurons following acoustic trauma remains to be elucidated. The present study investigated how auditory cortical PV neurons change following unilateral 1 hour noise exposure (left ear, one octave band noise centered at 16 kHz, 116 dB SPL). Noise exposure elevated the auditory brainstem response threshold of the exposed ear when examined 7 days later. More detectable PV neurons were observed in both sides of the auditory cortex of noise exposed rats when compared to control. The detectable PV neurons of the left auditory cortex (ipsilateral to the exposed ear) to noise exposure outnumbered those of the right auditory cortex (contralateral to the exposed ear). Quantification of Western blotted bands revealed higher expression level of PV protein in the left cortex. These findings of more active PV neurons in noise exposed rats suggested that a compensatory mechanism might be initiated to maintain a stable state of the brain. PMID- 29593787 TI - Utilization of Smartphone Applications by Anesthesia Providers. AB - Health care-related apps provide valuable facts and have added a new dimension to knowledge sharing. The purpose of this study is to understand the pattern of utilization of mobile apps specifically created for anesthesia providers. Smartphone app stores were searched, and a survey was sent to 416 anesthesia providers at 136 anesthesiology residency programs querying specific facets of application use. Among respondents, 11.4% never used, 12.4% used less than once per month, 6.0% used once per month, 12.1% used 2-3 times per month, 13.6% used once per week, 21% used 2-3 times per week, and 23.5% used daily. Dosage/pharmaceutical apps were rated the highest as most useful. 24.6% of the participants would pay less than $2.00, 25.1% would pay $5.00, 30.3% would pay $5 $10.00, 9.6% would pay $10-$25.00, 5.1% would pay $25-$50.00, and 5.1% would pay more than $50.00 if an app saves 5-10 minutes per day or 30 minutes/week. The use of mobile phone apps is not limited to reiterating information from textbooks but provides opportunities to further the ever-changing field of anesthesiology. Our survey illustrates the convenience of apps for health care professionals. Providers must exercise caution when selecting apps to ensure best evidence-based medicine. PMID- 29593785 TI - Circadian Regulation of Hippocampal-Dependent Memory: Circuits, Synapses, and Molecular Mechanisms. AB - Circadian modulation of learning and memory efficiency is an evolutionarily conserved phenomenon, occurring in organisms ranging from invertebrates to higher mammalian species, including humans. While the suprachiasmatic nucleus (SCN) of the hypothalamus functions as the master mammalian pacemaker, recent evidence suggests that forebrain regions, including the hippocampus, exhibit oscillatory capacity. This finding, as well as work on the cellular signaling events that underlie learning and memory, has opened promising new avenues of investigation into the precise cellular, molecular, and circuit-based mechanisms by which clock timing impacts plasticity and cognition. In this review, we examine the complex molecular relationship between clock timing and memory, with a focus on hippocampal-dependent tasks. We evaluate how the dysregulation of circadian timing, both at the level of the SCN and at the level of ancillary forebrain clocks, affects learning and memory. Further, we discuss experimentally validated intracellular signaling pathways (e.g., ERK/MAPK and GSK3beta) and potential cellular signaling mechanisms by which the clock affects learning and memory formation. Finally, we examine how long-term potentiation (LTP), a synaptic process critical to the establishment of several forms of memory, is regulated by clock-gated processes. PMID- 29593788 TI - In Vivo and In Vitro Toxicity Evaluation of Hydroethanolic Extract of Kalanchoe brasiliensis (Crassulaceae) Leaves. AB - The species Kalanchoe brasiliensis, known as "Saiao," has anti-inflammatory, antimicrobial, and antihistamine activities. It also has the quercetin and kaempferol flavonoids, which exert their therapeutic activities. With extensive popular use besides the defined therapeutical properties, the study of possible side effects is indispensable. The objective of this study is to evaluate the toxicity in vitro and in vivo from the hydroethanolic extract of the leaves of K. brasiliensis. The action of the extract (concentrations from 0.1 to 1000 uL/100 uL) in normal and tumor cells was evaluated using the MTT method. Acute toxicity and subchronic toxicity were evaluated in mice with doses of 250 to 1000 mg/kg orally, following recognized protocols. The in vitro results indicated cytotoxic activity for 3T3 cell line (normal) and 786-0 (kidney carcinoma), showing the activity to be concentration-dependent, reaching 92.23% cell inhibition. In vivo, the extract showed no significant toxicity; only liver changes related to acute toxicity and some signs of liver damage, combining biochemical and histological data. In general, the extract showed low or no toxicity, introducing itself as safe for use with promising therapeutic potential. PMID- 29593790 TI - Association between Dietary Patterns and Precocious Puberty in Children: A Population-Based Study. AB - Objective: The aim of the present study was to investigate the association between dietary patterns and precocious puberty among Shanghai children. Methods: A cross-sectional study was conducted among Shanghai children by multistage stratified cluster random sampling in June 2014. Diet was assessed using a simplified food frequency questionnaire (FFQ). Height, weight, and Tanner stages of breast development, pubic hair growth, and testicular volume were carefully measured. Exploratory factor analysis was used to identify dietary patterns, and logistic regression analysis was used to assess the association between dietary patterns and precocious puberty. Results: Three distinct dietary patterns, "traditional diet," "unhealthy diet," and "protein diet," were established. Neither the "traditional diet" pattern nor the "protein diet" pattern showed any association with precocious puberty, taking gender, BMI, and adjustment factors into consideration. The "unhealthy diet" pattern was significantly positively associated with precocious puberty in both boys (OR = 1.24, 95% CI = 1.02-1.51) and girls (OR = 1.31, 95% CI = 1.10-1.56). The relationship remained positive only for girls (OR = 1.25, 95% CI = 1.04-1.49) after adjustment for age and BMI but statistically nonsignificant after further adjustment for socioeconomic factors in both boys and girls. Conclusions: Dietary patterns were found to be related to precocious puberty among Shanghai children. PMID- 29593791 TI - Histopathological Characterization and Whole Exome Sequencing of Ectopic Thyroid: Fetal Architecture in a Functional Ectopic Gland from Adult Patient. AB - Ectopic thyroid results from a migration defect of the developing gland during embryogenesis causing congenital hypothyroidism. But it has also been detected in asymptomatic individuals. This study aimed to investigate the histopathological, functional, and genetic features of human ectopic thyroids. Six samples were histologically examined, and the expression of the specific thyroid proteins was assessed by immunohistochemistry. Two samples were submitted to whole exome sequencing. An oropharynx sample showed immature fetal architecture tissue with clusters or cords of oval thyrocytes and small follicles; one sample exhibited a normal thyroid pattern while four showed colloid goiter. All ectopic thyroids expressed the specific thyroid genes and T4 at similar locations to those observed in normal thyroid. No somatic mutations associated with ectopic thyroid were found. This is the first immature thyroid fetal tissue observed in an ectopic thyroid due to the arrest of structural differentiation early in the colloid stage of development that proved able to synthesize thyroid hormone but not to respond to TSH. Despite the ability of all ectopic thyroids to synthetize specific thyroid proteins and T4, at some point in life, it may be insufficient to support body growth leading to hypothyroidism, as observed in some of the patients. PMID- 29593792 TI - GH, IGF-1, and Age Are Important Contributors to Thyroid Abnormalities in Patients with Acromegaly. AB - Purpose: To determine the prevalence, risk factors, and possible mechanisms of structural and endocrinological changes to the thyroid in acromegaly. Methods: We studied 93 acromegalic patients from PUMCH between January 2013 and December 2013. The demographic and clinical information were recorded. Specimens of pituitary adenomas and thyroid cancer were collected for BRAF mutation assessments. Results: Thyroid morphological abnormalities were found in 72 (77.4%) patients. Three (3.2%) were diagnosed with thyroid cancer. The thyroid gland volume was significantly increased in patients with higher random GH (p = 0.01), higher nadir GH (p = 0.008), and higher IGF-1 level (p = 0.018). Age (p = 0.002) was an independent risk factor for thyroid morphological abnormalities in acromegaly. The GH burden was significantly higher in patients with thyroid morphological abnormalities (p = 0.036). The BRAF V600E mutation was detected in the PTCs of the two patients with thyroid cancer. Conclusions: Both benign and malignant thyroid abnormalities are increased in the acromegalic population compared to those in the general population. Age at diagnosis is an independent risk factor for thyroid abnormalities, and GH burden may be a partial contributor. Early diagnosis, early treatment, and monitoring of postoperational endocrine levels are important for acromegalic patients. PMID- 29593789 TI - Drugs Involved in Dyslipidemia and Obesity Treatment: Focus on Adipose Tissue. AB - Metabolic syndrome can be defined as a state of disturbed metabolic homeostasis characterized by visceral obesity, atherogenic dyslipidemia, arterial hypertension, and insulin resistance. The growing prevalence of metabolic syndrome will certainly contribute to the burden of cardiovascular disease. Obesity and dyslipidemia are main features of metabolic syndrome, and both can present with adipose tissue dysfunction, involved in the pathogenic mechanisms underlying this syndrome. We revised the effects, and underlying mechanisms, of the current approved drugs for dyslipidemia and obesity (fibrates, statins, niacin, resins, ezetimibe, and orlistat; sibutramine; and diethylpropion, phentermine/topiramate, bupropion and naltrexone, and liraglutide) on adipose tissue. Specifically, we explored how these drugs can modulate the complex pathways involved in metabolism, inflammation, atherogenesis, insulin sensitivity, and adipogenesis. The clinical outcomes of adipose tissue modulation by these drugs, as well as differences of major importance for clinical practice between drugs of the same class, were identified. Whether solutions to these issues will be found in further adjustments and combinations between drugs already in use or necessarily in new advances in pharmacology is not known. To better understand the effect of drugs used in dyslipidemia and obesity on adipose tissue not only is challenging for physicians but could also be the next step to tackle cardiovascular disease. PMID- 29593793 TI - Soft Lithography and Minimally Human Invasive Technique for Rapid Screening of Oral Biofilm Formation on New Microfabricated Dental Material Surfaces. AB - Introduction: Microfabrication offers opportunities to study surface concepts focused to reduce bacterial adhesion on implants using human minimally invasive rapid screening (hMIRS). Wide information is available about cell/biomaterial interactions using eukaryotic and prokaryotic cells on surfaces of dental materials with different topographies, but studies using human being are still limited. Objective: To evaluate a synergy of microfabrication and hMIRS to study the bacterial adhesion on micropatterned surfaces for dental materials. Materials and Methods: Micropatterned and flat surfaces on biomedical PDMS disks were produced by soft lithography. The hMIRS approach was used to evaluate the total oral bacterial adhesion on PDMS surfaces placed in the oral cavity of five volunteers (the study was approved by the University Ethical Committee). After 24 h, the disks were analyzed using MTT assay and light microscopy. Results: In the present pilot study, microwell structures were microfabricated on the PDMS surface via soft lithography with a spacing of 5 um. Overall, bacterial adhesion did not significantly differ between the flat and micropatterned surfaces. However, individual analysis of two subjects showed greater bacterial adhesion on the micropatterned surfaces than on the flat surfaces. Significance: Microfabrication and hMIRS might be implemented to study the cell/biomaterial interactions for dental materials. PMID- 29593794 TI - Comparative Analysis of the Effectiveness of the Topical Administration of Benzocaine and EMLA(r) on Oral Pain and Tactile Sensitivity. AB - Objectives: To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. Materials and Methods: A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. The sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. Results: In the superficial tactile perception test, when we compared each group singly, there were statistically significant values in the decrease of superficial tactile perception when compared to the moment prior to the application of anesthetic agents. For the sensitivity to mechanical pain, no statistical significant difference was observed at evaluated times. In the needle penetration test, in an intergroup analysis, we found a decrease in the pain sensitivity to needle penetration at 5 min (p=0.053) and at 10 min (p=0.019) after the contact of the anesthetic drug with the oral mucosa. Conclusion: The application of topical anesthetic drugs reduces the discomfort associated with this procedure, mainly until the first 10 minutes. Only the needle penetration sensitivity test showed sufficient sensitivity to reveal a difference in the anesthetic effect between EMLA and benzocaine. This trial is registered with RBR-2N2GSW. PMID- 29593795 TI - The Role and Impact of Salivary Zn Levels on Dental Caries. AB - Introduction: Minimal attention has been given to the role of salivary microelements, the importance they have in reducing the intensity of caries, and the effect of caries prophylaxes. Aim: This research aimed to determine the concentration and quantity of Zn and its impact on the prevention and the reduction of the intensity of caries in schoolchildren aged 12-13 years with permanent dentition. Methods: For this research, we analyzed the stimulated and nonstimulated full saliva of 106 schoolchildren divided into three groups by mean decayed, missing, and filled teeth (DMFT) index. The control group consisted of 25 caries-free children, the second group had 47 children with mean DMFT index of 1 to 6, and the third group had 34 children with DMFT index of >= 6. Complete saliva was collected from all children in a sterile test tube. Results: The concentration of Zn in saliva before stimulation in caries-free children has variations of the order of 0.001+ to 0.01 mmol/l. The maximum concentration after stimulation is 6.72 mmol/l, while the maximum value is 64.38 mmol/l. Conclusion: The Zn concentration in the stimulated saliva showed a significant increase in the group of caries-free children and could be described as a positive value for the reduction of caries. PMID- 29593796 TI - Application of D-Amino Acids as Biofilm Dispersing Agent in Dental Unit Waterlines. AB - Aim and Purpose: Biofilms in dental unit waterlines (DUWLs) are extremely difficult to eliminate. Aim of this study is to evaluate the efficacy of a mixture of four D-amino acids on biofilm dispersion in DUWLs. Materials and Methods: A mixture of four D-amino acids (D-methionine, D-tryptophan, D-leucine, and D-tyrosine, 10 mM each), distilled water (control), and 0.1 M hydrochloric acid (HCl) was used in the experiment. In laboratory, pieces of DUWLs covered with biofilms were submerged in different solutions for 5 days, flushed, and measured OD600 of the dispersed biofilms. Remnants of biofilms on the DUWLs were evaluated by SEM. In clinic, fifteen DCUs were incubated with test and control solutions, flushed, and measured OD600 of the dispersed biofilms. Microbial count of DUWL output water was enumerated twice a week for four weeks. Results: There was a slight, but not significant, increase in OD600 of flushing water in D-amino acids group. D-amino acids effectively reduced bacterial plaque as demonstrated by SEM. Incubation with D-amino acids significantly reduced biofilms especially after the first day of flushing. Bacterial count in DUWL output water was significantly reduced after treatment with D-amino acids. Conclusion: D-amino acids are applicable as biofilm dispersing agents in DUWLs. PMID- 29593797 TI - Factors influencing P terminal force in lead V1 of the ECG in hemodialysis patients. AB - Introduction: Atrial fibrillation (AF) is a highly prevalent arrhythmia in hemodialysis (HD) patients, and an HD session may be a trigger for AF episodes. An abnormal P-terminal force in lead V1 (PTFV1) may predict new-onset AF in HD patients. The aim of the study was to assess the influence of the HD process on PTFV1 and to evaluate possible factors influencing PTFV1 in a group of selected HD patients. Material and methods: One hundred and fifty-three selected HD patients entered the study. Blood chemistry, electrocardiography, and impedance cardiography were evaluated before and after HD. Echocardiography was performed on the morning after dialysis. Abnormal PTFV1 was defined as PTFV1 > 40 mm * ms. Results: Abnormal PTFV1 was found in 35.3% of patients before dialysis and in 48.4% of patients after dialysis. The results of multiple regression analysis revealed that the independent predictors of pre-dialysis abnormal PTFV1 were: left atrial volume index (p = 0.002), left ventricular mass index (p = 0.014), and pre-dialysis thoracic fluid content (p = 0.021) values. The independent predictors of HD-induced abnormal PTFV1 values were larger differences between pre-dialysis and post-dialysis values of serum potassium (p < 0.001) and mean arterial pressure (p = 0.008). Conclusions: Abnormal PTFV1 is prevalent in HD patients. The HD process adversely affects PTFV1 values. Pre-dialysis abnormal PTFV1 is mainly associated with structural heart abnormalities and hydration status. HD-induced abnormal PTFV1 is associated predominantly with serum potassium changes as well as HD-induced hypotension. Our results suggest possible risk factors for AF; however, their clinical significance needs to be confirmed in follow-up studies. PMID- 29593798 TI - Depressive symptoms but not chronic pain have an impact on the survival of patients undergoing maintenance hemodialysis. AB - Introduction: More than 1/3 of patients with end-stage renal disease who are in a chronic dialysis program suffer from chronic pain and depression/anxiety. The aim of the study was to determine the impacts of symptoms of depression/anxiety, chronic pain and quality of life (QoL) on 6-year patient survival. Material and methods: Observational study of end-stage renal disease patients on maintenance hemodialysis (n = 205) who met the inclusion criteria. Patients from three dialysis centers in Lower Silesia were asked to complete a battery of validated questionnaires: the Hospital Anxiety and Depression Scale (HADS), the 36-item Short Form Health Survey Questionnaire, the Verbal Rating Scale (VRS) and the Visual Analog Scale (VAS). Clinical and biochemical data (dialysis adequacy) were recorded. Results: One hundred thirty from 205 enrolled hemodialysis patients (63.4%) suffered from chronic pain. Patients with pain were on maintenance dialysis for longer times and had higher levels of parathyroid hormone, more depressive symptoms and a lower QoL than those without pain. In the 6-year period, 96 (46.8%) patients died. The most common cause of death was cardiovascular disease in 44 (45.8%) patients. Highly depressed patients (HADS depression score > 8) exhibited higher mortality (< 8 vs. > 8 points; p = 0.016) independent of age, diabetes, cardiovascular disease, C-reactive protein or albumin level. Conclusions: Chronic pain, although common among hemodialysis patients, did not lower survival. Depressive symptoms are an important predictor for all-cause mortality in hemodialysis patients, with the relationship independent of nutritional or inflammatory status. PMID- 29593799 TI - Comparison of the efficacy and safety of hybrid and sequential therapies as a first-line regimen for Helicobacter pylori infection in Turkey. AB - Introduction: Helicobacter pylori infection is a common infection worldwide. The most frequently recommended treatment for eradication of H. pylori remains triple therapy. In this study, we compared sequential and hybrid regimens for H. pylori eradication in a region of Turkey with high resistance to clarithromycin. Material and methods: Three hundred and forty H. pylori-positive patients were enrolled in the study. The subjects were randomly divided into two groups. The first group (170 patients) received rabeprazole (40 mg/b.i.d.) and amoxicillin (1000 mg/b.i.d.) for 2 weeks and metronidazole and clarithromycin (500 mg/b.i.d.) during the second week in the hybrid therapy group. The second group (170 patients) received rabeprazole (40 mg/b.i.d.) for 14 days, amoxicillin (1000 mg/b.i.d.) for the first 7 days, and metronidazole plus clarithromycin (each 500 mg/b.i.d.) during the next 7 days in the sequential therapy group. Results: In the per-protocol analysis, the eradication rate in the hybrid therapy group was 96.1% (147/153), and in the sequential therapy group it was 90.9% (140/154). There was no significant difference between the two groups (p = 0.06). Ninety seven of those 340 patients reported minor adverse drug reactions. The percentages of patients with adverse reactions were 30.6% in the hybrid therapy group and 26.5% in the sequential therapy group (p = 0.74). Conclusions: Both therapies are highly effective for eradication of H. pylori, and could be recommended as a first-line therapy in regions with high antibiotic resistance. PMID- 29593800 TI - Activity of alcohol dehydrogenase isoenzymes and aldehyde dehydrogenase in sera of patients with hepatitis C. AB - Introduction: The changes of enzyme activity in the hepatocytes in the course of different liver diseases are reflected by increase of the corresponding enzyme activity in the plasma. For example, the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) correlate with the severity of the condition during cirrhosis. In this study we measured the activity of ADH isoenzymes and ALDH in the sera of patients with hepatitis C. Material and methods: Serum samples were taken from 60 patients suffering from viral hepatitis C and from 66 control subjects. Total ADH activity and class III and IV isoenzymes were measured by the photometric method and ALDH activity, ADH I and II by the fluorometric method. Results: The ADH activity was significantly higher in patients with hepatitis C than in healthy (p < 0.001). The total activity of ADH was 1284 mU/l in patients, and 745 mU/l (controls). The activity of isoenzymes classes ADH I and ADH II in the hepatitis C group increased respectively 55% (4.24 vs. 1.88 mU/l; p < 0.001) and 47% (26.63 vs. 14.11 mU/l; p < 0.001) in the comparison to the control. There was significant increase in the activity of ADH I isoenzyme (4.96 vs. 3.81 mU/l; p < 0.001) and ADH total (1833 vs. 1105 mU/l; p < 0.001) in patients with high viral load in comparison to patients with low viral load. Conclusions: The activity of class I and II ADH isoenzymes in the sera of patients with hepatitis C is increased, and it seems to be caused by the release of these isoenzymes from damaged liver cells. PMID- 29593801 TI - Inflammatory mediators in the diagnosis and treatment of acute pancreatitis: pentraxin-3, procalcitonin and myeloperoxidase. AB - Introduction: Acute pancreatitis (AP) is the third most common gastrointestinal disease at hospital admission. The etiology and pathogenesis of this disease are not completely clear. Our study was intended to determine the systemic levels of pentraxin-3 (PTX-3), myeloperoxidase (MPO), procalcitonin (PCT), and C-reactive protein (CRP) as prognostic parameters in early stages of AP. We also determined the effects of treatment on PTX-3, MPO, PCT and CRP levels in AP. Material and methods: The study group comprised 44 AP patients (22 male, 22 female; age: 49.3 +/-16.9 years) referred to our outpatient clinic. Additionally, our investigation included a control group of 30 healthy volunteers (18 male, 12 female; age: 50.8 +/-12.6 years). Results: Leukocytes, glucose, aspartate aminotransferase (AST (SGOT)), alanine aminotransferase (ALT (SGPT)), alkaline phosphatase (ALP), total and direct bilirubin levels were significantly higher in the AP group (p < 0.05, all). CRP, PTX-3, MPO and PCT were considerably higher in the AP group (p < 0.001, all), and after treatment, CRP, PTX-3, MPO and PCT levels were significantly lower (p < 0.001, all). Conclusions: Our findings indicated that the CRP, PTX-3, MPO and PCT levels increase in patients with AP and hence these indicators can be used as diagnostic factors to predict inflammation severity in AP. It was revealed that after treatment, there were significant reductions in biomarker levels. However, further research is needed in order to understand how these biomarkers can help to monitor inflammatory responses in AP. PMID- 29593802 TI - Oxygen dependence of endothelium-dependent vasodilation: importance in chronic obstructive pulmonary disease. AB - Introduction: Epidemiological studies have shown increased morbidity and mortality in patients with coronary artery disease (CAD) and chronic obstructive pulmonary disease (COPD). We aimed to characterize the oxygen dependence of endothelial function in patients with CAD and coexisting COPD. Material and methods: In CAD patients with and without COPD (n = 33), we non-invasively measured flow-mediated dilation (FMD) and intima-media thickness (IMT) of the brachial artery (BA), forearm blood flow (FBF), and perfusion of the cutaneous microcirculation with laser Doppler perfusion imaging (LDPI). In an experimental setup, vascular function was assessed in healthy volunteers (n = 5) breathing 12% oxygen or 100% oxygen in comparison to room air. Results: COPD was associated with impaired FMD (3.4 +/-0.5 vs. 4.2 +/-0.6%; p < 0.001) and increased IMT (0.49 +/-0.04 vs. 0.44 +/-0.04 mm; p <0.01), indicating functional and structural alterations of the BA in COPD. Forearm blood flow and LDPI were comparable between the groups. Flow-mediated dilation correlated with capillary oxygen pressure (pO2, r = 0.608). Subgroup analysis in COPD patients with pO2 > 65 mm Hg and pO2 <= 65 mm Hg revealed even lower FMD in patients with lower pO2 (3.0 +/ 0.5 vs. 3.7 +/-0.4%; p < 0.01). Multivariate analysis showed that pO2 was a predictor of FMD independent of the forced expiratory volume and pack years. Exposure to hypoxic air led to an acute decrease in FMD, whereby exposure to 100% oxygen did not change vascular function. Conclusions: Our data suggest that in CAD patients with COPD, decreased systemic oxygen levels lead to endothelial dysfunction, underlining the relevance of cardiopulmonary interaction and the potential importance of pulmonary treatment in secondary prevention of vascular disease. PMID- 29593803 TI - Can we define migraine patients with blood high-sensitivity C-reactive protein and galectin-3 levels in the emergency department? AB - Introduction: Migraine, the most widespread cause of headache in young adults, is a frequent reason for presentation to emergency departments. The aim of this study was to determine the diagnostic value of serum galectin-3 and high sensitivity C-reactive protein (hsCRP) levels in migraine patients. Material and methods: Serum galectin-3 and hsCRP levels were measured using enzyme-linked immunosorbent assay in 70 migraine patients and 70 healthy control subjects. Results: The mean values of hsCRP and galectin-3 levels were significantly higher in the migraine group than those in the control group (1.67 +/-0.49, 1.12 +/-0.38 mg/l, p < 0.001; and 3.76 +/-1.45, 2.05 +/-0.29 ng/ml, p < 0.001, respectively). When the diagnostic values of the biomarkers were assessed in the migraine attack and control groups, the sensitivity and specificity of the test for hsCRP at the cut-off point of 1.32 mg/l were 70% and 73% (AUC = 0.805, 95% CI: 0.74-0.88, p < 0.001), and for galectin-3 at the cut-off point of 2.4 ng/ml, 89% and 90% (AUC = 0.97, 95% CI: 0.95-0.99, p < 0.001), respectively. Conclusions: This study showed the presence of a relation between high serum levels of hsCRP and galectin-3 in migraine patients. However, well-controlled, carefully executed longitudinal studies are required to confirm these findings. PMID- 29593804 TI - CXCL9 concentrations in cerebrospinal fluid and serum of patients with tick-borne encephalitis. AB - Introduction: The aim of our current study was to evaluate cerebrospinal fluid (CSF) and serum CXCL9 concentrations and diagnostic usefulness of this molecule in tick-borne encephalitis (TBE). The study included TBE patients in the acute phase (TBE I) and after 2 weeks of follow-up (TBE II). The control group consisted of patients investigated for suspected central nervous system (CNS) infection, but with normal CSF findings. Material and methods: Concentrations of CXCL9 were measured using enzyme-linked immunosorbent assay (ELISA). Results: Cerebrospinal fluid and serum concentrations of CXCL9 in patients with TBE were significantly higher than in controls (p < 0.001). This alteration was also observed in the case of the CXCL9 index (ICXCL9; CSF CXCL9 concentration divided by serum CXCL9 concentration) (p < 0.001); moreover, ICXCL9 significantly decreased after 2 weeks (p < 0.001). This is the first study to evaluate the CSF and serum levels of CXCL9 in subjects with TBE. Conclusions: CXCL9 is a ligand for CXCR3, which was found on all Th1 memory lymphocytes present in the peripheral blood; therefore the elevated concentrations of CXCL9 in TBE patients as compared to the controls might indicate that this chemokine perhaps takes part in the trafficking of Th1 cells into the CNS. The results presented here support the hypothesis that CXCL9 may play a role in TBE. However, further studies are required to determine whether this protein might be used as a potential tool for the diagnosis and monitoring of inflammation in TBE. PMID- 29593805 TI - Evaluating the introduction of intraoperative neuromonitoring of the recurrent laryngeal nerve in thyroid and parathyroid surgery. AB - Introduction: Paresis of the recurrent laryngeal nerve (RLN) is a complication of thyroid surgery. Neuromonitoring as is gaining acceptance among surgeons. The aim of the study was to assess the number of technical problems in the initial phase of intraoperative neuromonitoring (IONM) use and the specificity, sensitivity, positive predictive value and negative predictive value of neuromonitoring. The number of cases of postoperative paresis (transient and permanent) was assessed. Material and methods: The prospective analysis included 101 thyroid operations with IONM (190 RLNs at risk of injury) in the period from January to April, 2012. Demographic data, rate of RLN identification, sensitivity, specificity and predictive value of the method, the duration of the procedure and the percentage of RLN paresis were considered. Results: The RLN was identified in 92% of the cases. Technical problems were observed in 12.98%, of which 61% were due to incorrect positioning of the endotracheal tube electrodes in relation to the vocal cords. The sensitivity, specificity, negative and positive predictive value and the accuracy of the method were respectively 71%, 98%, 62.5%, 98.9% and 97%. Early nerve injury occurred in 3.7% of the cases; 2.6% were temporary paresis and 1.1% permanent. Conclusions: During the initial stages of implementing IONM we experienced technical problems that required correction in every tenth patient. The positive predictive value was relatively low; nevertheless, good results in terms of the rate of accurate identification of the RLN as well as the low rate of RLN paresis support the use of this method. PMID- 29593806 TI - Consequences of bleeding after thyroid surgery - analysis of 7805 operations performed in a single center. AB - Introduction: Surgical treatment of thyroid gland diseases is associated with the possibility of severe complications. The most dangerous of them is bleeding. Current studies focus on its risk factors, rather than reoperation-related consequences. Material and methods: We analyzed 7805 thyroid operations performed from 1996 to 2014 in the Clinic of General, Gastroenterological and Endocrine Surgery of Wroclaw Medical University. Typical risk factors, symptoms and consequences of bleeding were analyzed. Results: Among operated patients 88.2% were female and 11.8% male. Bleeding occurred in 84 (1.08%) patients. Sex (p = 0.006), preoperative thyroid pathology (p = 0.03), and type of operation (p < 0.001) are significant risk factors for bleeding, while retrosternal goiter and surgeon's experience are not. Risk of bleeding is highest in the case of male sex, toxic goiter and total resection of the thyroid gland. Most reoperations took place within 6 h. In 88.8% of cases of this kind of complication the surgeon indicated the exact source of bleeding; most commonly it was the neck muscles, skin and subcutaneous tissue, or the thyroid stump. Three patients required a second reoperation, 24 suffered further complications, and 8 required transfer to the Intensive Care Unit (ICU). Cardiac arrest occurred in 3 patients and 2 suffered bilateral vocal cord palsy. Conclusions: Bleeding after thyroid operations is a direct life threat that requires immediate intervention. As a result death may occur, half of patients suffer other complications and some require intensive care. The risk is highest in the case of male sex, toxic goiter and total resection of the thyroid gland. Each patient after thyroid surgery needs to be closely observed. An operating theatre and ICU should be available at all times. PMID- 29593807 TI - Enhanced healing and anti-inflammatory effects of a carbohydrate polymer with zinc oxide in patients with chronic venous leg ulcers: preliminary results. AB - Introduction: Insufficient wound healing related to chronic inflammation of chronic venous leg ulcers (CVUs) represents an important public health problem. The aim of this study was to evaluate the effects of a carbohydrate polymer with zinc oxide therapy on CVUs. Material and methods: Forty patients with CVUs were recruited for this study and were divided into a study group and control group. Patients In the study group were instructed to use venous compression treatment andtopical carbohydrate polymer with zinc oxide twice daily, while patients In the control group were treated with only venous compression treatment. All patients were followed up for 8 weeks. Peripheral blood samples and biosy tissue specimens were obtained at the initiation of treatment and after 8 weeks to assess serum levels of inflammatory cytokines as well as the percentage of leukocytes, T-helper cells, cytotoxic-T cells, macrophages and endothelial cells in the biopsy tissue using flow cytometry. Results: A significantly greater reduction in the mean percentage ulcer area from baseline to eight weeks was observed in the study group (up to 40% for large ulcers). Furthermore, the patients in the study group had reduced systemic levels of the pro-inflammatory cytokines IL-8 (p = 0.0028) and IL-6 (p = 0.0302), fewer total CD45+ cells (p = 0.0038) and more CD31+ cells (p = 0.045) present in ulcer biopsies compared to the control group. Conclusions: The carbohydrate polymer with zinc oxide treatment with venous compression enhances healing of CVUs and improves quality of life due, in part, to its anti-inflammatory properties. PMID- 29593808 TI - Evaluation of the validity of treatment decisions based on surrogate country models before introduction of the Polish FRAX and recommendations in comparison to current practice. AB - Introduction: Patients diagnosed before the Polish FRAX was introduced may require re-evaluation and treatment changes if the diagnosis was established according to a surrogate country FRAX score. The aim of the study was to evaluate the validity of treatment decisions based on the surrogate country model before introduction of the Polish FRAX and to provide recommendations based on the current practice. Material and methods: We evaluated a group of 142 postmenopausal women (70.7 +/-8.9 years) who underwent bone mineral density measurements. We used 22 country-specific FRAX models and compared these to the Polish model. Results: The mean risk values for hip and major osteoporotic fractures within 10 years were 4.575 (from 0.82 to 8.46) and 12.47% (from 2.18 to 21.65), respectively. In the case of a major fracture, 94.4% of women would receive lifestyle advice, and 5.6% would receive treatment according to the Polish FRAX using the guidelines of the National Osteoporosis Foundation (NOF). Polish treatment thresholds would implement pharmacotherapy in 32.4% of the study group. In the case of hip fractures, 45% of women according to the NOF would require pharmacotherapy but only 9.8% of women would qualify according to Polish guidelines. Nearly all surrogate FRAX calculator scores proved significantly different form Polish (p > 0.05). Conclusions: More patients might have received antiresorptive medication before the Polish FRAX. This study recommends re evaluation of patients who received medical therapy before the Polish FRAX was introduced and a review of the recommendations, considering the side effects of antiresorptive medication. PMID- 29593809 TI - The impact of age, sex, blepharitis, rosacea and rheumatoid arthritis on Demodex mite infection. AB - Introduction: Two human-specific Demodex species have been described: Demodex folliculorum and Demodex brevis. A medical condition caused by the presence of Demodex is called demodicosis. Material and methods: The study material comprised eyelashes collected from 1499 patients. Results: Demodex sp. infection was revealed in 47% of patients (487 women and 216 men). We determined the following rates of infection by age groups: 1-25 (8% of infected subjects), 26-40 (36%), 41 55 (50%), 56-70 (67%), over 70 (77%). The sex of the subjects was not identified as a factor conducive to infection (p = 0.108), while their age was positively correlated with the risk of infection (p < 0.005). The 1499 study subjects included patients with blepharitis, rosacea, and rheumatoid arthritis. The study investigated the extent to which the above-mentioned conditions affect the risk of Demodex infection. Applying the method of logistic regression, the infection probability was estimated, depending on the age, sex, and comorbidities such as blepharitis, rosacea, and rheumatoid arthritis. Patients suffering from blepharitis were found to have a nearly 2.5-fold higher risk of Demodex infection than those without blepharitis, and the risk for rosacea patients was determined as three-fold higher than that of the general population. Conclusions: Blepharitis and rosacea are risk factors for Demodex infection. PMID- 29593810 TI - Francisella tularensis/Rickettsia spp. co-infections in patients with skin changes and lymphadenopathy. AB - Introduction: Tularemia and spotted fever group rickettsioses (SFG) can be transmitted by ticks and have a number of common clinical symptoms. Most characteristic are a maculopapular or vesicular rash or an eschar at the site of the tick or insect bite accompanied by painful lymph nodes. The aim of this study was to determine whether Rickettsia spp./Francisella tularensis mixed infections occurred in patients with similar symptoms who were diagnosed with either Rickettsia spp. or F. tularensis infection. Material and methods: Thirty-six cases from 2011-2014, including 15 individuals with clinically and serologically recognized SFG and 21 with tularemia, were analyzed retrospectively using immunofluorescence for detection of Rickettsia spp. or ELISA for detection of F. tularensis. Results: Of the 36 cases examined, specific high titers of antibodies to Rickettsia spp. were found in 1 (4.4%) patient with tularemia and specific high titers of antibodies to F. tularensis were detected in 1 (6.7%) patient with SFG. Conclusions: The results of our study show that in infections with fever, enlarged lymph nodes and skin lesions after tick and insect bites, laboratory testing of both diseases - SFG rickettsiosis and tularemia - should be implemented. Identification of F. tularensis and Rickettsia spp. mixed infections is crucial in order to administer appropriate antibiotics and to avoid treatment failure and relapse. PMID- 29593811 TI - Expression of selected genes of dendritic and Treg cells in blood and skin of morphea patients treated with UVA1 phototherapy. AB - Introduction: Morphea is a chronic autoimmune disease characterized by fibrosis of the skin. Dendritic cells (DC) and regulatory T cells (Tregs) play a significant role in development of autoimmune and tolerance mechanisms. The aim of the study was to establish the expression of selected genes of plasmacytoid and myeloid DC, Treg cells, and the microenvironment of cytokines (interleukin 17A (IL-17A), transforming growth factor beta (TGF-beta)) in blood and skin of morphea patients. In addition, the effect of UVA1 phototherapy on expression of the aforementioned genes was evaluated. Material and methods: The study was performed on 15 blood and 10 skin samples from patients with morphea. The evaluation included expression of CLEC4C (C-type lectin domain family 4, member C receptor), Lymphocyte antigen 75 (LY75), Forkhead box p3 (foxp3) transcription factor, IL-17A and TGF-beta genes in peripheral blood mononuclear cells (PBMC) and in skin samples both before and after UVA1 phototherapy using real-time polymerase chain reaction. Results: The study revealed lower expression of CLEC4C before (p = 0.010) and after (p = 0.009) phototherapy and lower expression of IL 17A before (p = 0.038) phototherapy in PBMC of patients with morphea vs. the control group. Expression of CLEC4C in PBMC correlated negatively (rho = -0.90; p = 0.001) with activity of disease after phototherapy. No significant differences were found between expression of analysed genes before and after UVA1 therapy in PBMC and skin of morphea patients. Conclusions: The results do not confirm the involvement of analysed subsets of DC and Tregs in UVA1 phototherapy in morphea, but point to CLEC4C as a possible biomarker associated with the disease activity. PMID- 29593812 TI - The effect of celastrol on learning and memory in diabetic rats after sevoflurane inhalation. AB - Introduction: The aim was to devise an animal model showing some of the neuropathological changes seen in senile dementia, and to investigate the effect of celastrol on cognition neuropathology in this model. Material and methods: Forty male Sprague Dawley rats weighing 300-350 g were randomly divided into 5 groups (n = 8 each): control (Con); inhaled sevoflurane (Sev); diabetes mellitus (DM); diabetes mellitus + inhaled sevoflurane (DM/Sev); diabetes + inhaled sevoflurane + celastrol (Cel). Diabetes was induced by an intraperitoneal injection of streptozotocin (STZ). After 20 days, the Sev, DM/Sev and Cel group rats inhaled 3% sevoflurane for 2 h, while the control and DM groups inhaled air. Cel group rats were given intraperitoneal injections of celastrol (0.7 mg/kg) daily for 4 days, while the control group received intraperitoneal injections of an equal volume of dimethylsulfoxide. The Morris water maze test was performed to test cognition. Animals were killed after the last water maze test and Congo red staining was used to observe deposition of amyloid substance in the hippocampus. The expression of GFAP and IGF-1 in the hippocampus was observed by immunohistochemistry. Results: Diabetes decreased cognition, increased amyloid substance and GFAP expression, and decreased IGF-1 expression in the hippocampus (all p-values < 0.05). Sevoflurane administration intensified and celastrol decreased these changes (all p-values < 0.05). Conclusions: Sev/DM rats showed cognitive and neurochemical changes similar to those seen in senile dementia. Celastrol decreased these changes and should be evaluated further as a possible clinical agent in dementia. PMID- 29593813 TI - The role of vitamin E in the prevention of zoledronic acid-induced nephrotoxicity in rats: a light and electron microscopy study. AB - Introduction: Bisphosphonates are widely used in metastatic cancer such as prostate and breast cancer, and their nephrotoxic effects have been established previously. In this study we aimed to evaluate both the nephrotoxic effects of zoledronic acid (ZA) and the protective effects of vitamin E (Vit-E) on this process under light and electron microscopy. Material and methods: A total of 30 male Sprague-Dawley rats were divided into 3 groups. The first group constituted the control group. The second group was given i.v. ZA of 3 mg/kg once every 3 weeks for 12 weeks from the tail vein. The third group received the same dosage of ZA with an additional i.m. injection of 15 mg Vit-E every week for 12 weeks. Tissues were taken 4 days after the last dose of ZA for histopathological and ultrastructural evaluation. Paller score, tubular epithelial thickness and basal membrane thickness were calculated for each group. Results: For group 2, the p values are all < 0.001 for Paller score, epitelial thickness, and basal membrane thickness. For group 3 (ZA + Vit. E), the p-values are < 0.001 for Paller score, 0.996 for epitelial thickness, and < 0.001 basal membrane thickness. Significant differences were also observed in ultrastructural changes for group 2. However, adding Vit-E to ZA administration reversed all the histopathological changes to some degree, with statistical significance. Conclusions: Administration of ZA had nephrotoxic effects on rat kidney observed under both light and electron microscopy. Concomitant administration of Vit-E significantly reduces toxic histopathological effects of ZA. PMID- 29593814 TI - Age-related differences in function and structure of rat livers subjected to ischemia/reperfusion. AB - Introduction: Liver function is affected during ischemia/reperfusion (IR). The current state of knowledge about liver aging processes during IR is incomplete. We evaluated the effects of aging on liver structure and function under IR conditions. Material and methods: Animals were divided into control (C-2) and ischemia/reperfusion (IR-2) groups of young rats (2-4 months old) and C-12 and IR 12 groups of old rats (12-14 months old). The livers from IR-2 and IR-12 groups were subjected to partial ischemia (60 min), followed by global reperfusion (4 h). Blood samples were obtained during reperfusion (0, 30 and 240 min) to estimate the activity of aminotransferases (ALT, AST). After IR, tumor necrosis factor-alpha (TNF-alpha), interleukin-1b (IL-1b), malondialdehyde (MDA), and superoxide dismutase (SOD) were determined in liver homogenates. Results: At all points of reperfusion, an increase in aminotransferase activity levels in the ischemic groups was observed; mainly between IR-12 and C-12 rats. The concentration of TNF-alpha was significantly higher in young animals (in non ischemic groups: p = 0.09, in ischemic groups: p = 0.05). Under IR conditions, the concentration of IL-1b dropped (p = 0.05). The concentration of MDA was significantly higher in mature animals (in non-ischemic groups: p = 0.09, in ischemic groups: p = 0.05). In ischemic groups an increase in necrosis rate was observed regardless of age. Rats in the IR-12 group showed the most pronounced changes in hepatic architecture, including increased micro- and macrosteatosis and parenchymal cell destruction. Conclusions: The function and structure of mature livers slightly deteriorate with age and these differences are more noticeable under IR conditions. PMID- 29593815 TI - Preventive effects of total saponins of Panax japonicus on fatty liver fibrosis in mice. AB - Introduction: Nonalcoholic fatty liver disease (NAFLD) is a condition in which excess fat accumulates in the liver of a patient without a history of alcohol abuse. Fatty liver fibrosis, a severe form of NAFLD, is a key step which can be reversed by effective medical intervention. This paper aims to describe the protective role and mechanisms of action of total saponins of Panax japonicus (SPJ) against fatty liver fibrosis in mice. In this study, fatty liver fibrosis was induced by a high-fat (HF) diet combined with intraperitoneal injection of porcine serum. Material and methods: The fatty liver fibrosis model was induced by HF diet combined with intraperitoneal injection of porcine serum. The endoplasmic reticulum stress (ERS) response and C/EBP homologous protein (CHOP) and p-Jun N-terminal kinase (JNK)-mediated apoptosis and inflammation were assessed by serum biochemistry, hematoxylin-eosin (H + E), Masson and electronic microscopy staining, Hyp content detection, Western blotting and real time polymerase chain reaction (RT-PCR). Results: Saponins of Panax japonicus could significantly improve liver function and decrease the lipid level in the serum. The liver steatosis, collagen fibers and inflammatory cell infiltration were significantly improved in the SPJ group according to microscope observation. The RT-PCR analysis revealed that the collagen I (Coll), alpha smooth muscle actin (alpha-SMA), tissue inhibitors of MMPs (TIMP), CHOP and GRP78 mRNA expression levels were distinctly weakened by SPJ treatment; and western blotting analysis indicated that the phosphorylated JNK (p-JNK), Coll and 78 kD glucose-regulated protein (GRP78) protein expression levels were significantly alleviated, which might be associated with the inhibition of the ERS response and the CHOP and JNK mediated apoptosis and inflammation pathway. Conclusions: Based on this research, SPJ as a preventive medicine has great potential in prevention of liver fibrosis. PMID- 29593816 TI - Pancreatic-like enzymes of microbial origin restore growth and normalize lipid absorption in a pig model with exocrine pancreatic insufficiency. AB - Introduction: The standard therapy for exocrine pancreatic insufficiency (EPI) is porcine-derived pancreatic enzyme replacement therapy (PERT). In the present study we tested a new approach with a mixture of pancreatic-like enzymes of microbial origin (PLEM) in a 1-week efficacy study in EPI pigs. In addition to the conventionally used coefficient of fat and nitrogen absorption (CFA and CNA), parameters that more accurately reflect the nutritional and health status, such as changes in the lipemic index (LI), plasma triglyceride (TG) and non-esterified fatty acid (NEFA) levels, and somatic growth, were determined. Material and methods: A PLEM dose containing 120 000 active lipase units, 80 000 active protease units and 12 000 active amylase units (all from Sigma, St. Louis, MO) was given as a powder, twice daily with a meal (40 g fat/meal) to 8 EPI pigs for 7 days. Ten healthy pigs were used as a comparator. Results: The PLEM enhanced fat and protein digestion, and reversed growth impairment in EPI pigs. With treatment, CFA and CNA increased by 59% and 43% (p < 0.05), respectively. Although fat and protein absorption were lower than in the comparator, the postprandial blood lipid profile was normal as in healthy pigs. The mucosal thickness significantly increased by 27%, 50% and 26%, in the proximal, middle, and distal jejunum (p < 0.05) with treatment and resembled that of healthy animals. Conclusions: Pancreatic-like enzymes of microbial origin supported somatic growth and normalized the postprandial lipid profile. As a measure of efficacy, postprandial LI, TG and NEFA are viable endpoints to be explored in human trials. PMID- 29593817 TI - Identification of toxic metals in human embryonic tissues. AB - Introduction: The cause of a significant number of miscarriages remains unexplained. There is a need to identify the potential role of environmental, dietary and lifestyle factors in the risk of pregnancy loss. The present study was the first to investigate the content of miscarried embryonic material with respect to eight metals (aluminium, cadmium, chromium, copper, manganese, nickel, lead and zinc). Material and methods: Embryonic tissue samples (n = 20) were obtained from women undergoing misoprostol-induced removal of the embryo between the 6th and 9th week of gestation. The content of metals was analyzed using microwave-induced nitrogen plasma atomic emission spectrometry. Based on a short questionnaire, the smoking habits, dietary patterns and place of living of the investigated women were determined. Results: The general mean content of metals (MUg/g) decreased in the order copper (33.9) > manganese (24.7) > chromium (13.6) > zinc (13.3) > aluminium (6.5) > nickel (3.0) > lead (2.9) > cadmium (2.5). Profoundly increased concentrations (p < 0.05) of the toxic elements aluminium (over 5-fold), cadmium (over 2-fold) and lead (over 2-fold) were observed in samples obtained from former smoking women. The miscarried material in urban populations also revealed higher levels of cadmium (over 1.5-fold) and lead (over 2-fold) compared to that obtained from women living in rural areas (p < 0.05). No associations with age or diet were found (p > 0.05). Conclusions: This study identified increased levels of aluminum, cadmium and lead in miscarried embryonic material and suggests some causative factors. PMID- 29593819 TI - Morphological and clinical aspects of the occurrence of accessory (multiple) renal arteries. AB - Renal vascularization variants vastly differ between individuals due to the very complex embryogenesis of the kidneys. Moreover, each variant may have implications for clinical and surgical interventions. The number of operating procedures continues to grow, and includes renal transplants, aneurysmorrhaphy and other vascular reconstructions. In any surgical technique, unawareness of the presence of multiple renal arteries may result in a fatal outcome, especially if laparoscopic methods are used. The aim of this review is to comprehensively identify the variation within multiple renal arteries and to highlight the connections between the presence of accessory renal arteries and the coexistence of other variants of vascularization. Another aim is to determine the potential clinical implications of the presence of accessory renal arteries. This study is of particular importance for surgeons, intervention radiologists, nephrologists and vascular surgeons. PMID- 29593820 TI - Prophylaxis of medial compartment gonarthrosis in varus knee - current state of knowledge. AB - The progression of gonarthrosis results in reduction of physical activity. One of the factors that increase the risk of osteoarthrosis may be joint overload related to the malalignment of the mechanical axis of the lower extremity. The medial compartment (MC) of the knee is particularly susceptible to overload due to the external knee adduction moment (EKAM). Varus knee malalignment contributes to increased EKAM and thus results in increased MC loading. The purpose of this study is to present methods described in current literature aimed at reducing the disproportion in the distribution of loads on articular surfaces of medial and lateral knee compartments in people with varus knee malalignment. Methods have been divided into non-surgical (gait training, physiotherapy, and orthopedic supplies such as valgus braces, lateral wedge insoles, walking poles) and surgical ones (corrective osteotomy). PMID- 29593821 TI - Myocarditis due to systemic lupus erythematosus associated with cardiogenic shock. PMID- 29593818 TI - Natural approaches in metabolic syndrome management. AB - Metabolic syndrome (MetS) is characterized as a group of cardiometabolic risk factors that raise the risk for heart disease and other health problems, such as diabetes mellitus and stroke. Treatment strategies include pharmacologic interventions and supplementary (or "alternative") treatments. Nutraceuticals are derived from food sources (isolated nutrients, dietary supplements and herbal products) that are purported to provide health benefits, in addition to providing basic nutritional value. Nutraceuticals are claimed to prevent chronic diseases, improve health, delay the aging process, increase life expectancy, and support the structure and function of the body. The study of the beneficial effects of nutraceuticals in patients with MetS, including product standardization, duration of supplementation and definition of optimal dosing, could help better define appropriate treatment. This review focuses on widely marketed nutraceuticals (namely polyphenols, omega-3 fatty acids, macroelements and vitamins) with clinically demonstrated effects on more than one component of MetS.

AB - Background: Guard cell protoplasts (GCPs) isolated from various plants have proven to be especially useful for studies of signal transduction pathways and plant development. But it is not easy to isolate highly purified preparations of large numbers of GCPs from plants. In this research, our focus is on a method to isolate large numbers of guard cells from tomato leaves. The protocols described yield millions of highly purified, viable GCPs, which are also suitable for studies on guard cell physiology. Results: We developed an efficient method for isolating GCPs from epidermal fragments of tomato leaves. The protocol requires a two-step digestion to isolate high-quality tomato GCPs. In this procedure, cellulysin (in method L) was replaced by cellulose "Onozuka" RS (in method S) in the first digestion step, which indicated that cellulase RS was more effective than cellulysin. Method S dramatically shortened the time required for obtaining high yields and high-quality GCPs. Moreover, according to the GCP yields, hydroponic plants were more effective than substrate-cultured plants. Conclusions: In this paper, protocols for large-scale preparation of GCPs and mesophyll cell protoplasts were described, followed by some success examples of their use in biochemical and molecular approaches such as reverse-transcription polymerase chain reaction, real-time polymerase chain reaction and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The method was proved to be a more efficient GCP-isolating method, capable of providing high yields with better quality in less time. PMID- 29593829 TI - 2017 and all that. PMID- 29593828 TI - Electrocardiogram Delineation in a Wistar Rat Experimental Model. AB - Background and Objectives: The extensive use of electrocardiogram (ECG) recordings during experimental protocols using small rodents requires an automatic delineation technique in the ECG with high performance. It has been shown that the wavelet transform (WT) based ECG delineator is a suitable tool to delineate electrocardiographic waveforms. The aim of this work is to implement and evaluate the ECG waves delineation in Wistar rats applying WT. We also describe the ECG signal of the Wistar rats giving the characteristics of its spectrum among other useful information. Methods: We evaluated a delineator based on WT in a Wistar rat electrocardiograms database which was annotated manually by experienced observers. Results: The delineation showed an "overall performance" such as sensitivity and a positive predictive value of 99.2% and 83.9% for P wave, 100% and 99.9% for QRS complex, and 100% and 99.8% for T-wave, respectively. We also compared temporal analysis based ECG delineator with the WT based ECG delineator in RR interval, QRS duration, QT interval, and T-wave peak to-end duration. The results showed that WT outperforms the temporal delineation technique in all parameters analyzed. Conclusions: Finally, we propose a WT based ECG delineator as a methodology to implement in a wide diversity of experimental ECG analyses using Wistar rats.

AB - Functional tricuspid regurgitation (TR) represents an important unmet need in clinical cardiology given its prevalence, adverse prognostic impact and symptom burden associated with progressive right heart failure. Several transcatheter techniques are currently in early clinical testing to provide alternative treatment options for patients deemed unsuitable for tricuspid valve surgery. Amongst them, the TrialignTM device (Mitralign, Inc.) represents a novel percutaneous tricuspid valve annuloplasty technique, which aims to reduce tricuspid annular dilatation in functional TR by delivering and cinching two pledgeted sutures to the posterior portion of the tricuspid annulus via transjugular access. Early clinical data suggest the Trialign technique is safe and feasible, and associated with an improvement in quality-of-life measures. However, further studies are needed to confirm these data in larger cohorts of patients with longer follow up. In addition, future trials need to address the question whether TR reduction with the Trialign and other devices leads to an improvement in the patient's functional status and prognosis, over and above medical treatment alone. PMID- 29593831 TI - Minimally Invasive Surgical Mitral Valve Repair: State of the Art Review. AB - Minimally invasive surgical mitral valve repair (MVRepair) has become routine for the treatment of mitral valve regurgitation, and indications have been expanded to include reoperations. Current European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines for the management of valvular heart disease recommended standards in terms of mitral valve disease differentiation, timing of intervention and surgical techniques to improve patient care. Numerous minimally invasive techniques to lessen the invasiveness have been described, such as the minimal-access J-sternotomy (ministernotomy), the parasternal incision, the port-access technique and the right minithoracotomy. Despite the development of catheter-based techniques, surgical repair remains the gold standard today for nearly all patients with degenerative valvular diseases and the majority of patients with other types of valvular diseases. Techniques include resection of the prolapsed segment, neo-chordae implantation and ring annuloplasty. In this review, the current indications for mitral valve surgery are summarised and state-of-the-art MVRepair techniques are highlighted. PMID- 29593832 TI - Bioprosthetic Valve Fracture During Valve-in-valve TAVR: Bench to Bedside. AB - Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) has been established as a safe and effective means of treating failed surgical bioprosthetic valves (BPVs) in patients at high risk for complications related to reoperation. Patients who undergo VIV TAVR are at risk of patient-prosthesis mismatch, as the transcatheter heart valve (THV) is implanted within the ring of the existing BPV, limiting full expansion and reducing the maximum achievable effective orifice area of the THV. Importantly, patient-prosthesis mismatch and high residual transvalvular gradients are associated with reduced survival following VIV TAVR. Bioprosthetic valve fracture (BVF) is as a novel technique to address this problem. During BPV, a non-compliant valvuloplasty balloon is positioned within the BPV frame, and a highpressure balloon inflation is performed to fracture the surgical sewing ring of the BPV. This allows for further expansion of the BPV as well as the implanted THV, thus increasing the maximum effective orifice area that can be achieved after VIV TAVR. This review focuses on the current evidence base for BVF to facilitate VIV TAVR, including initial bench testing, procedural technique, clinical experience and future directions. PMID- 29593833 TI - Understanding Neurologic Complications Following TAVR. AB - Transcatheter aortic valve replacement is a groundbreaking treatment modality for severe, symptomatic aortic stenosis. Despite the rapid progression in indications to include intermediate-risk patients, the risk of peri-procedural stroke remains, with a higher incidence rate than previously reported. Accurate assessment of peri-procedural stroke rates requires selection of careful and meaningful trial endpoints during evaluation of neuroprotective devices. In this article, we review recommendations and stroke definitions from academic research consortiums along with device trial results. PMID- 29593834 TI - Oral Anticoagulant Therapy for Early Post-TAVI Thrombosis. AB - While transcatheter aortic valve implantation (TAVI) is now the accepted treatment option of choice for patients presenting with severe symptomatic aortic stenosis who are deemed to be inoperable or of high surgical risk, there have been concerns regarding the risk of early valve failure and durability. One potential limitation is the occurrence of early post-TAVI thrombosis. Whilst the incidence of obstructive transcatheter heart valve (THV) thrombosis is <1 %, with technological advances in imaging, it is increasingly apparent that the overall true incidence is likely to be much higher with between 7-40 % of patients observed to have appearances strongly suggestive of asymptomatic subclinical THV thrombosis. This short review discusses the diagnosis of early THV thrombosis and the role of anticoagulation therapy for the management of these patients. PMID- 29593835 TI - Assessing the Risk of Leaflet Motion Abnormality Following Transcatheter Aortic Valve Implantation. AB - Leaflet motion abnormalities are a relatively new entity in the field of transcatheter aortic valve implantation and are associated with a range of different conditions, the extreme being prosthetic valve dysfunction with high gradients or central regurgitation and possibly early thrombotic degeneration. Another extreme condition is the incidental finding of leaflet thickening, but with normal transvalvular gradients. Transthoracic echocardiography is a useful screening tool for the detection of symptomatic thrombosis, but it has limited use in the detection of subclinical thrombosis and/or motion abnormalities alone. We, hereby, discuss the evidence for the potential screening process and subsequent management of those conditions associated with the leaflet motion abnormalities. PMID- 29593836 TI - Challenges in Patients with Diabetes: Improving Clinical Outcomes After Percutaneous Coronary Intervention Through EVOlving Stent Technology. AB - Patients with diabetes have poorer outcomes after percutaneous coronary intervention than patients without diabetes. The Cre8TM EVO drug-eluting stent (DES) has design features that aim to improve clinical outcomes in patients with diabetes. These include Abluminal Reservoir Technology - a proprietary polymer free drug-release system consisting of reservoirs on the abluminal surface of the stent that control drug release and direct the drug exclusively towards the vessel wall - and the AmphilimusTM drug formulation, which enables enhanced drug tissue permeation utilising fatty acid transport pathways. The latter is particularly advantageous in patients with diabetes, whose cell metabolism favours increased cellular uptake of fatty acid. Furthermore, evidence suggests that mTOR inhibitors (-limus drugs) utilised in conventional DES are less effective in diabetic cells. The new stent architecture provides high device deliverability and conformability, facilitating clinical use in complex disease patterns and high-risk lesion morphologies. Clinical evidence for the efficacy and safety of the Cre8TM DES in patients with diabetes has been demonstrated in a number of clinical trials and observational registries. These data are reviewed herein, along with an overview of on-going randomised trials. PMID- 29593837 TI - Is Complete Revascularisation Mandated for all Patients with Multivessel Coronary Artery Disease? AB - In multivessel coronary artery disease (MVCAD), myocardial revascularisation can be achieved by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), with complete revascularisation on all diseased coronary segments or with incomplete revascularisation on selectively targeted lesions. Complete revascularisation confers a long-term prognostic benefit, but is associated with a higher rate of periprocedural events compared with incomplete revascularisation. In most patients with MVCAD, the main advantage of CABG over PCI is conferred by the achievement of more extensive revascularisation. According to current international guidelines, PCI is generally preferred in single-vessel disease, low-risk MVCAD or isolated left main disease; whereas CABG is usually recommended in patients with complex two-vessel disease, most patients with three-vessel disease and/or non-isolated left main disease. In patients with MVCAD, the choice on revascularisation modality should depend on a multifactorial evaluation, taking into account not only coronary anatomy, the ischaemic burden, myocardial function, age and the presence of comorbidities, but also the adequacy of myocardial revascularisation. PMID- 29593838 TI - B cell-based therapies in CNS autoimmunity: differentiating CD19 and CD20 as therapeutic targets. AB - Increasing recognition of the role of B cells in the adaptive immune response makes B cells an important therapeutic target in autoimmunity. Numerous current and developmental immunotherapies target B cells for elimination through recognition of cell-surface proteins expressed specifically on B cells, in particular CD19 and CD20. Similarities and differences in the function and expression of these two molecules predict some shared, and some distinct, pharmacological effects of agents targeting CD19 versus CD20, potentially leading to differences in the clinical safety and efficacy of such agents. Here, we review current knowledge of CD19 and CD20 function and biology, survey current and developmental therapies that target these molecules, and discuss potential differences in elimination of B cells by drugs that target CD19 versus CD20, with particular focus on the central nervous system autoimmune diseases multiple sclerosis and neuromyelitis optica. The principles and mechanisms herein discussed might also be relevant to a variety of other nervous system autoimmune disorders, including NMDA (N-methyl-D-aspartate) receptor encephalitis, transverse myelitis and myasthenia gravis. PMID- 29593839 TI - Optimal early active mobilisation protocol after extensor tendon repairs in zones V and VI: A systematic review of literature. AB - Introduction: Early mobilisation protocols after repair of extensor tendons in zone V and VI provide better outcomes than immobilisation protocols. This systematic review investigated different early active mobilisation protocols used after extensor tendon repair in zone V and VI. The purpose was to determine whether any one early active mobilisation protocol provides superior results. Methods: An extensive literature search was conducted to identify articles investigating the outcomes of early active mobilisation protocols after extensor tendon repair in zone V and VI. Databases searched were AMED, Embase, Medline, Cochrane and CINAHL. Studies were included if they involved participants with extensor tendon repairs in zone V and VI in digits 2-5 and described a post operative rehabilitation protocol which allowed early active metacarpophalangeal joint extension. Study designs included were randomised controlled trials, observational studies, cohort studies and case series. The Structured Effectiveness Quality Evaluation Scale was used to evaluate the methodological quality of the included studies. Results: Twelve articles met the inclusion criteria. Two types of early active mobilisation protocols were identified: controlled active motion protocols and relative motion extension splinting protocols. Articles describing relative motion extension splinting protocols were more recent but of lower methodological quality than those describing controlled active motion protocols. Participants treated with controlled active motion and relative motion extension splinting protocols had similar range of motion outcomes, but those in relative motion extension splinting groups returned to work earlier. Discussion: The evidence reviewed suggested that relative motion extension splinting protocols may allow an earlier return to function than controlled active motion protocols without a greater risk of complication.

PMID- 29593840 TI - Mediational Model of Multiple Sclerosis Impairments, Family Needs, and Caregiver Mental Health in Guadalajara, Mexico. AB - Individuals with multiple sclerosis (MS), especially those living in Latin America, often require assistance from family caregivers throughout the duration of the disease. Previous research suggests that family caregivers may experience positive and negative outcomes from providing care to individuals with MS, but few studies have examined the unmet needs of individuals providing care to family members with MS and how these unmet needs may mediate the relationship between MS symptoms and caregiver mental health. The current study examined the relationships among MS impairments (functional, neurological, cognitive, behavioral, and emotional), unmet family needs (household, informational, financial, social support, and health), and caregiver mental health (satisfaction with life, anxiety, burden, and depression) in a sample of 81 MS caregivers from Guadalajara, Mexico. A structural equation model demonstrated the mediational effect of unmet family needs on the relationship between MS impairments and caregiver mental health. These findings suggest that intervention research on MS caregivers in Latin America may consider focusing on caregiver mental health problems by addressing unmet family needs and teaching caregivers ways to manage the impairments of the individual with MS. PMID- 29593842 TI - Integration of Massage Therapy in Outpatient Cancer Care. AB - Background: Massage therapy can be helpful in alleviating cancer-related symptoms and cancer treatment-related symptoms. While surveys have noted that cancer patients seek out massage as a nonpharmacologic approach during cancer treatment, little is known about the integration of massage in outpatient cancer care. Purpose: The purpose of this study was to examine the extent to which massage is being integrated into outpatient cancer care at NCI-designated Cancer Centers. Setting: This study used descriptive methods to analyze the integration of massage in NCI-designated Cancer Centers providing clinical services to patients (n = 62). Design: Data were collected from 91.1% of the centers (n = 59) using content analysis and a telephone survey. A dataset was developed and coded for analysis. Main Outcome Measure: The integration of massage was assessed by an algorithm that was developed from a set of five variables: 1) acceptance of treatment as therapeutic, 2) institution offers treatment to patients, 3) clinical practice guidelines in place, 4) use of evidence-based resources to inform treatment, and 5) shared knowledge about treatment among health care team. All centers were scored against all five variables using a six-point scale, with all variables rated equally. Results: The integration of massage ranged from not at all (0) to very high (5) with all five levels of integration evident. Only 11 centers (17.7% of total) rated a very high level of integration; nearly one-third of the centers (n = 22) were found to have no integration of massage at all-not even provision of information about massage to patients through the center website. Conclusions: The findings of this analysis suggest that research on massage is not being leveraged to integrate massage into outpatient cancer care. PMID- 29593843 TI - A Regional Analysis of U.S. Insurance Reimbursement Guidelines for Massage Therapy. AB - Introduction: Massage techniques fall within the scope of many different health care providers. Physical therapists, occupational therapists, and chiropractors receive insurance reimbursement for health care services, including massage. Although many patients pay out of pocket for massage services, it is unclear how the insurance company reimbursement policies factor provider qualifications into coverage. This project examined regional insurance reimbursement guidelines for massage therapy in relation to the role of the provider of massage services. Methods: A qualitative content analysis was used to explore guidelines for 26 health insurance policies across seven US companies providing coverage in the northeastern United States. Publicly available information relevant to massage was obtained from insurance company websites and extracted into a dataset for thematic analysis. Data obtained included practice guidelines, techniques, and provider requirements. Information from the dataset was coded and analyzed using descriptive statistics. Results: Of the policies reviewed, 23% explicitly stated massage treatments were limited to 15-minute increments, 19% covered massage as one part of a comprehensive rehabilitation plan, and 27% required physician prescription. Massage techniques mentioned as qualifying for reimbursement included: Swedish, manual lymphatic drainage, mobilization/manipulation, myofascial release, and traction. Chiropractors, physical therapists, and occupational therapists could directly bill for massage. Massage therapists were specifically excluded as covered providers for seven (27%) policies. Conclusion: Although research supports massage for the treatment of a variety of conditions, the provider type has not been separately addressed. The reviewed policies that served the Northeastern states explicitly stated massage therapists could not bill insurance companies directly. The same insurance companies examined reimbursement for massage therapists in their western U.S. state policies. Other health care providers were able to bill directly for massage services to companies that did not accept direct billing by massage therapists. The specific exclusion of massage therapists as eligible providers violates the Affordable Care Act's non-discriminatory provision. Massage therapists should continue to advocate for reimbursement privileges to spur wider acceptance of massage therapy in health care. PMID- 29593844 TI - Fertility Massage: an Unethical Practice? PMID- 29593845 TI - Cancer Screening Among U.S. Medicaid Enrollees with Chronic Comorbidities or Residing in Long-Term Care Facilities. AB - Background: Ensuring appropriate cancer screenings among low-income persons with chronic conditions and persons residing in long-term care (LTC) facilities presents special challenges. This study examines the impact of having chronic diseases and of LTC residency status on cancer screening among adults enrolled in Medicaid, a joint state-federal government program providing health insurance for certain low-income individuals in the U.S. Methods: We used 2000-2003 Medicaid data for Medicaid-only beneficiaries and merged 2003 Medicare-Medicaid data for dually-eligible beneficiaries from four states to estimate the likelihood of cancer screening tests during a 12-month period. Multivariate regression models assessed the association of chronic conditions and LTC residency status with each type of cancer screening. Results: LTC residency was associated with significant reductions in screening tests for both Medicaid-only and Medicare-Medicaid enrollees; particularly large reductions were observed for receipt of mammograms. Enrollees with multiple chronic comorbidities were more likely to receive colorectal and prostate cancer screenings and less likely to receive Papanicolaou (Pap) tests than were those without chronic conditions. Conclusions: LTC residents have substantial risks of not receiving cancer screening tests. Not performing appropriate screenings may increase the risk of delayed/missed diagnoses and could increase disparities; however, it is also important to consider recommendations to appropriately discontinue screening and decrease the risk of overdiagnosis. Although anecdotal reports suggest that patients with serious comorbidities may not receive regular cancer screening, we found that having chronic conditions increases the likelihood of certain screening tests. More work is needed to better understand these issues and to facilitate referrals for appropriate cancer screenings. PMID- 29593846 TI - New insights into Nod-like receptors (NLRs) in liver diseases. AB - Activation of inflammatory signaling pathways is of central importance in the pathogenesis of alcoholic liver disease (ALD) and nonalcoholic steatohepatitis (NASH). Nod-like receptors (NLRs) are intracellular innate immune sensors of microbes and danger signals that control multiple aspects of inflammatory responses. Recent studies demonstrated that NLRs are expressed and activated in innate immune cells as well as in parenchymal cells in the liver. For example, NLRP3 signaling is involved in liver ischemia-reperfusion (I/R) injury and silencing of NLRP3 can protect the liver from I/R injury. In this article, we review the evidence that highlights the critical importance of NLRs in the prevalent liver diseases. The significance of NLR-induced intracellular signaling pathways and cytokine production is also evaluated. PMID- 29593848 TI - Saturated fatty acids bound to albumin enhance osteopontin expression and cleavage in renal proximal tubular cells. AB - Osteopontin (OPN) is one of the proinflammatory cytokines upregulated in the kidneys of diabetic animals and patients with nephropathy. An increase in urinary albumin and albumin-bound fatty acids (FA) presents a proinflammatory environment to the proximal tubules in proteinuric kidney diseases including diabetic nephropathy. This study was designed to examine if FA overload could stimulate OPN expression and cleavage in renal tubule epithelial cells. OPN gene and protein expression was examined in the kidney of Zucker diabetic (ZD) rats and cultured proximal tubular cells exposed to either bovine serum albumin (BSA) or BSA conjugated with palmitic acid (PA), the most abundant saturated plasma FA. Real-time PCR analysis confirmed an upregulation of renal cortical OPN gene correlated with albuminuria and nephropathy progression in ZD rats at the age of 7-20 weeks. Immunofluorescence staining of kidney sections revealed a massive induction of OPN protein in albumin-overloaded proximal tubules of ZD rats. A significant increase in both intact and cleaved OPN proteins was further demonstrated in the diabetic kidney and urine samples, which was attenuated by antiproteinuric treatment with losartan, an angiotensin II receptor blocker. When exposed to fatty acid-free BSA, NRK-52E cells exhibited an increase in protein levels of full-length and cleaved OPN. Moreover, the increase in OPN fragments was greatly enhanced in the presence of PA (250-500 uM). Together, our results support a stimulatory effect of albumin and conjugated FA on OPN expression and cleavage in renal tubule epithelial cells. Thus, besides lowering albuminuria/proteinuria, mitigating circulating FAs may be an effective intervention for preventing and slowing down the progression of nephropathy associated with obesity and type 2 diabetes. PMID- 29593847 TI - The crosstalk between autonomic nervous system and blood vessels. AB - The autonomic nervous system (ANS), comprised of two primary branches, sympathetic and parasympathetic nervous system, plays an essential role in the regulation of vascular wall contractility and tension. The sympathetic and parasympathetic nerves work together to balance the functions of autonomic effector organs. The neurotransmitters released from the varicosities in the ANS can regulate the vascular tone. Norepinephrine (NE), adenosine triphosphate (ATP) and Neuropeptide Y (NPY) function as vasoconstrictors, whereas acetylcholine (Ach) and calcitonin gene-related peptide (CGRP) can mediate vasodilation. On the other hand, vascular factors, such as endothelium-derived relaxing factor nitric oxide (NO), and constriction factor endothelin, play an important role in the autonomic nervous system in physiologic conditions. Endothelial dysfunction and inflammation are associated with the sympathetic nerve activity in the pathological conditions, such as hypertension, heart failure, and diabetes mellitus. The dysfunction of the autonomic nervous system could be a risk factor for vascular diseases and the overactive sympathetic nerve is detrimental to the blood vessel. In this review, we summarize findings concerning the crosstalk between ANS and blood vessels in both physiological and pathological conditions and hope to provide insight into the development of therapeutic interventions of vascular diseases. PMID- 29593849 TI - Ascorbic acid and sodium benzoate synergistically aggravates testicular dysfunction in adult Wistar rats. AB - BACKGROUND: The effect of the concomitant use of sodium benzoate (NaB) and ascorbic acid on human health remains controversial. Therefore, the current study is designed to investigate the effect of NaB and ascorbic acid on the testicular function of adult Wistar rats. METHODS: Adult Wistar rats were randomly allotted into Control (vehicle; received 1 ml of distilled water), NaB-treated (SB treated; received 100 mg/kg body weight; b.w), ascorbic acid-treated (AA-treated; received 150 mg/kg b.w) and NaB+ ascorbic acid-treated (SB+AA-treated) groups. The treatment lasted for 28 days and the administration was given orally. The body weight change was monitored. Semen analysis, biochemical assay and histological examination were performed. RESULTS: Treatment with NaB significantly altered the cytoarchitecture of testicular tissue, sperm quality, testicular endocrine function and oxidative stress status without any alteration in body weight gain compared to control. In addition, treatment with NaB+ ascorbic acid exacerbated testicular tissue disruption, impaired sperm quality and testicular endocrine impairment with significant reduction in oxidative stress and unaltered body weight gain when compared with NaB-treated group. CONCLUSION: This study suggests that ascorbic acid and NaB synergistically aggravates testicular dysfunction. This is independent of oxidative stress status. PMID- 29593850 TI - Systemic delivery of selective EP1 and EP3 receptor antagonists attenuates pentylenetetrazole-induced seizures in mice. AB - Neuroinflammation plays a major role in brain excitability and may contribute to the development of epilepsy. Prostaglandin E2 (PGE2) is a direct mediator of inflammatory responses and, through EP receptors, plays an important role in neuronal excitability. Pharmacological evidence supports that centrally administered EP1 and EP3 receptor antagonists reduced acutely evoked seizures in rats. Translation of these findings would benefit from evidence of efficacy with a more clinically relevant route of delivery and validation in another species. In the current study we investigated whether the systemic administration of EP1 and EP3 agonists and antagonists modulate pentylenetetrazole (PTZ)-induced seizures in mice. In addition, it was examined whether these compounds alter Na+, K+-ATPase activity, an enzyme responsible for the homeostatic ionic equilibrium and, consequently, for the resting membrane potential in neurons. While the systemic administration of EP1 and EP3 antagonists (ONO-8713 and ONO-AE3-240, respectively) attenuated, the respective agonists (ONO-DI-004 and ONO-AE-248) potentiated PTZ-induced seizures (all compounds injected at the dose of 10 ug/kg, s.c., 30 min before PTZ challenge). Co-administration of either EP1 or EP3 agonist with the respective antagonists nullified the anticonvulsant effects of EP1/3 receptor blockade. In addition, EP1 and EP3 agonists exacerbated PTZ induced decrease of Na+, K+-ATPase activity in both cerebral cortex and hippocampus, whereas, EP1 and EP3 antagonists prevented PTZ-induced decrease of Na+, K+-ATPase activity in both structures. Our findings support and extend evidence that EP1 and EP3 receptors may be novel targets for the development of anticonvulsant drugs. PMID- 29593852 TI - Ideological Responses to the EU Refugee Crisis: The Left, the Right, and the Extremes. AB - The 2016 European Union (EU) refugee crisis exposed a fundamental distinction in political attitudes between the political left and right. Previous findings suggest, however, that besides political orientation, ideological strength (i.e., political extremism) is also relevant to understand such distinctive attitudes. Our study reveals that the political right is more anxious, and the political left experiences more self-efficacy, about the refugee crisis. At the same time, the political extremes-at both sides of the spectrum-are more likely than moderates to believe that the solution to this societal problem is simple. Furthermore, both extremes experience more judgmental certainty about their domain-specific knowledge of the refugee crisis, independent of their actual knowledge. Finally, belief in simple solutions mediated the relationship between ideology and judgmental certainty, but only among political extremists. We conclude that both ideological orientation and strength matter to understand citizens' reactions to the refugee crisis. PMID- 29593851 TI - Acupuncture for alcohol use disorder. AB - Alcohol use disorder (AUD) is a common medical and social problem, affecting about 240 million people in the world. To address this major health concern, the currently available treatments for AUD need to be improved. Acupuncture, a popular form of complementary and alternative therapy, is emerging as an effective treatment for AUD. This review summarizes how preclinical and clinical studies are related to the application of acupuncture for AUD. These studies suggest that if used correctly, acupuncture may effectively reduce alcohol intake, attenuate alcohol withdrawal syndrome, and rebalance AUD-induced maladaptation in neurotransmitters and hormones in related brain areas. The progress of research in this field is at an early stage. Future investigations with rigorous design and carefully constructed protocols are still needed. PMID- 29593853 TI - Complex cytogeographical patterns reveal a dynamic tetraploid-octoploid contact zone. AB - The distribution of cytotypes in mixed-ploidy species is crucial for evaluating ecological processes involved in the establishment and evolution of polyploid taxa. Here, we use flow cytometry and chromosome counts to explore cytotype diversity and distributions within a tetraploid-octoploid contact zone. We then use niche modelling and ploidy seed screening to assess the roles of niche differentiation among cytotypes and reproductive interactions, respectively, in promoting cytotype coexistence. Two cytotypes, tetraploids and octoploids, were dominant within the contact zone. They were most often distributed parapatrically or allopatrically, resulting in high geographic isolation. Still, 16.7 % of localities comprised two or more cytotypes, including the intermediate hexaploid cytotype. Tetraploids and octoploids had high environmental niche overlap and associated with similar climatic environments, suggesting they have similar ecological requirements. Given the geographical separation and habitat similarity among cytotypes, mixed-ploidy populations may be transitional and subject to the forces of minority cytotype exclusion which lead to pure-ploidy populations. However, seed ploidy analysis suggests that strong reproductive barriers may enforce assortative mating which favours stable cytotype coexistence. High cytogenetic diversity detected in the field suggests that unreduced gamete formation and hybridization events seem frequent in the studied polyploid complex and might be involved with the recurrent polyploid formation, governing, as well, the gene flow between cytogenetic entities. PMID- 29593854 TI - Expansive reed populations-alien invasion or disturbed wetlands? AB - The tall-statured grasses in the genus Phragmites are dominant vegetation in wetlands worldwide and thus play a vital role in ecosystem functioning. As a result, Phragmites spp. are some of the most widely studied plants; particularly in areas where changes to their abundances have occurred, most notably in Europe and North America. In southern Africa a pattern of reed expansion has occurred in recent decades that has shown a similar trend to cryptic invasions reported in North America. This study used molecular techniques to explore the phylogeography of P. australis and P. mauritianus in the region to investigate whether the expansion is due to an alien invasion or local factors such as wetland disturbance. Three haplotypes were found and all haplotypes are presently considered African haplotypes (haplotype K for P. australis and haplotype V and AP for P. mauritianus). Both Phragmites spp. were found to have high genetic diversity. Microsatellite and grass-waxy analysis also found evidence of hybridization between the two species. No evidence was found for a recent cryptic invasion of non-native haplotypes in southern Africa. The expansion of P. australis and P. mauritianus is therefore most likely a result of anthropogenic activity. Identifying and mitigating the human-mediated factors that may be contributing to reed growth, such as eutrophication and sedimentation, should be the focus of future management protocols. PMID- 29593855 TI - Novel 3D geometry and models of the lower regions of large trees for use in carbon accounting of primary forests. AB - There is high uncertainty in the contribution of land-use change to anthropogenic climate change, especially pertaining to below-ground carbon loss resulting from conversion of primary-to-secondary forest. Soil organic carbon (SOC) and coarse roots are concentrated close to tree trunks, a region usually unmeasured during soil carbon sampling. Soil carbon estimates and their variation with land-use change have not been correspondingly adjusted. Our aim was to deduce allometric equations that will allow improvement of SOC estimates and tree trunk carbon estimates, for primary forest stands that include large trees in rugged terrain. Terrestrial digital photography, photogrammetry and GIS software were used to produce 3D models of the buttresses, roots and humus mounds of large trees in primary forests dominated by Eucalyptus regnans in Tasmania. Models of 29, in situ eucalypts were made and analysed. 3D models of example eucalypt roots, logging debris, rainforest tree species, fallen trees, branches, root and trunk slices, and soil profiles were also derived. Measurements in 2D, from earlier work, of three buttress 'logs' were added to the data set. The 3D models had high spatial resolution. The modelling allowed checking and correction of field measurements. Tree anatomical detail was formulated, such as buttress shape, humus volume, root volume in the under-sampled zone and trunk hollow area. The allometric relationships developed link diameter at breast height and ground slope, to SOC and tree trunk carbon, the latter including a correction for senescence. These formulae can be applied to stand-level carbon accounting. The formulae allow the typically measured, inter-tree SOC to be corrected for not sampling near large trees. The 3D models developed are irreplaceable, being for increasingly rare, large trees, and they could be useful to other scientific endeavours.

Monarch larvae feed exclusively on milkweed species, primarily in the genus Asclepias, making propagation and restoration of these plants crucial for habitat restoration. Seed germination protocols for milkweeds are not well established, in part due to the large number of milkweed species and conflicting reports of seed dormancy in the genus. We tested for seed dormancy and the optimum period of cold stratification in 15 populations of A. speciosa and 1-2 populations of five additional species, including A. asperula, A. fascicularis, A. subulata, A. subverticillata and A. syriaca. We exposed seeds to cold (5 degrees C) moist conditions for 0, 2, 4, 6 and 8 weeks and then moved them to 15 degrees C/25 degrees C alternating temperatures. In A. speciosa, dormancy was detected in eight populations, and this dormancy was broken by 2-4 weeks of cold stratification. The remaining seven populations showed no dormancy. Seed dormancy was also detected in two populations of A. fascicularis (broken by 4-6 weeks of cold stratification) and a single population of A. syriaca (broken by 2 weeks of cold stratification). No dormancy was detected in A. asperula, A. subulata or A. subverticillata. Seed dormancy appears to be widespread in the genus (confirmed in 15 species) but can vary between populations even within the same species. Variation in seed dormancy and cold stratification requirements within and among Asclepias species suggests local adaptation and maternal environments may drive seedling ecology, and that growers should watch for low germination and use cold stratification as needed to maximize seed germination and retain genetic variability in restored populations.

AB - Tartar emetic (TE) was the first drug used to treat leishmaniasis. However, its use was discontinued due to high toxicity. Association of TE with liposomes is a strategy to reduce its side effects. Pegylated liposomes (Lpeg) present lower rates of uptake by macrophages and prolonged circulation compared to their nonpegylated counterparts. However, repeated administration of Lpeg can cause an Accelerated Blood Clearance (ABC) phenomenon, whereby recognition of liposomes by antibodies results in faster phagocytosis. This work evaluated the effect of TE administration on histopathological aspects and the effect of the ABC phenomenon on targeting and toxicity in mice. Our results show that treatment with free or liposomal TE had no effect on the erythrocyte count, on liver and spleen weight, and on hepatic, splenic, and cardiac histology in mice. Severe lesions were observed on the kidneys of animals treated with a single dose of free TE. Treatment with TE in Lpeg after induction of ABC phenomenon caused a significant increase in Sb level in the liver without toxicity. Furthermore, mice treated with TE in liposomes showed normal renal histopathology. These results suggest site-specific targeting of Sb to the liver after induction of ABC phenomenon with no toxicity to other organs. PMID- 29593858 TI - Chicken Coccidiosis in Central Java, Indonesia: A Recent Update. AB - Avian coccidiosis is a huge problem worldwide. Heavily infected animals that show severe clinical signs and coccidiostat resistance are causing important economic losses. The present study aimed to update the recent cases of coccidiosis in Central Java, Indonesia, and to show the importance of the disease in the region. A total of 699 samples were obtained from different chicken breed. Different Eimeria species were detected in 175 individuals (25.04%). Three different groups of chicken breed were considered: local chicken (autochthonous chickens of Sentul and Jawa), commercial broiler, and layer. Broiler chickens showed the highest prevalence of infection (34%), followed by layer (26.26%) and local chickens (10.45%). Mild to severe clinical signs of avian coccidiosis were observed in 42% of the infected animals, while 58% of the infected animals showed no clinical signs other than low feed conversion rates. Seven different Eimeria species were identified: E. tenella was the most prevalent (43.3%), followed by E. maxima (26.3%), E. necatrix (15.7%), E. acervulina (8%), E. praecox (3.1%), E. mitis (2.2%), and E. brunetti (1.3%). Coinfections with several Eimeria species were diagnosed. With this study we found massive usage of coccidiostat in the region even though its usage cannot guarantee coccidiosis-free chicken production. PMID- 29593860 TI - Potential drug-drug interactions with direct oral anticoagulants in elderly hospitalized patients. AB - Background: To determine the prevalence and nature of potential drug-drug interactions (DDIs) with direct oral anticoagulants (DOACs) in elderly hospitalized patients. Methods: This was a retrospective observational study. Inclusion criteria were: aged over 65 years; taking apixaban, rivaroxaban or dabigatran; and admitted to the Repatriation General Hospital between April 2014 and July 2015. A list of clinically relevant 'perpetrator' drugs was compiled from product information, the Australian Medicines Handbook, the Australian National Prescribing Service resources, and local health network guidelines. The prevalence and nature of potential DDIs with DOACs was determined by comparing inpatient drug charts with the list of perpetrator drugs. Results: There were 122 patients in the study with a mean age of 82 years. Most patients had nonvalvular atrial fibrillation and were taking DOACs to prevent thrombotic stroke (83%). Overall, 45 patients (37%) had a total of 54 potential DDIs. Thirty-five patients had potential pharmacodynamic DDIs with antidepressants, nonsteroidal anti inflammatory drugs and antiplatelets (35/122, 29%). Nineteen patients had potential pharmacokinetic DDIs (19/122, 16%). Of these, 68% (13/19) were taking drugs that increase DOAC plasma concentrations (amiodarone, erythromycin, diltiazem or verapamil) and 32% (6/19) were taking drugs that decrease DOAC plasma concentrations (carbamazepine, primidone or phenytoin). There were no cases of patients taking contraindicated interacting drugs. Discussion: Potential DDIs with DOACs in elderly hospital inpatients are relatively common, particularly interactions that may increase the risk of bleeding. The risk benefit ratio of DOACs in elderly patients on polypharmacy should always be carefully considered.

PMID- 29593859 TI - A threshold trajectory was revealed by isolating the effects of hemoglobin rate of rise in anemia of chronic kidney disease. AB - Background: To assess cardiovascular risk among various hemoglobin (Hb) rates of rise (RoR) in chronic kidney disease (CKD) patients with anemia who have initiated therapy with erythropoiesis stimulating agents (ESAs). Methods: Observational cohort of CKD patients initiating ESA therapy from the Centricity(r) database, 1990-2011. Proportional hazards models tested the hypothesis that a slower Hb RoR (0 < g/dl/month ? 0.125) is associated with a lower cardiovascular (CV) incidence [composite of fatal/nonfatal myocardial infarction (MI) and stroke] compared with faster RoR (0.125 < g/dl/month ? 2.0, and >2.0 g/dl/month). Results: A total of 9220 patients receiving ESAs were followed for an average of 3.1 years. Slow (group B) RoR versus medium (group C') and fast (group D') RoR in Hb, throughout all Hb milestones, was associated with lower risk of the composite endpoint [B (slow) versus D' (fast) [hazard ratio (HR) = 0.20 (0.11, 0.39), p < 0.0001]; B versus C' (medium) [HR = 0.34 (0.19, 0.62), p = 0.0004], and C' versus D' [HR = 0.60 (0.42, 0.85), p = 0.005]]. Within achieved Hb milestones, HRs were: B versus D' at milestone ? 14.1 g/dl [HR = 0.17 (0.05, 0.56); p = 0.004] and at milestone 12.6-14.0 [HR = 0.18 (0.07, 0.46), p = 0.0004]. Conclusion: Rapid Hb rise is associated with adverse CV outcomes, with markedly lower risk for rates below a threshold trajectory of 0.125 g/dl/month, even with complete correction.

AB - Seroma formation after axillary dissection is a common problem in breast cancer surgery. We report the case of a 68-year-old female with breast cancer who underwent a wide local excision and axillary clearance due to stage III breast cancer. Patient received post-operative whole breast irradiation therapy and developed a painful, infected seroma one month after surgery. This was treated with antibiotic therapy after which the infection subsided. One year after surgery patient presented with a painful persisting seroma in the left axilla. We decided to surgically treat the seroma by removing the fibrous seroma capsula and closing of the dead space with a latissimus dorsi flap. Six weeks after surgery, patient was pain and seroma free and was happy with the surgical result. Latissimus dorsi flap harvesting is an ideal way to treat persisting fibrous encapsulated seroma pockets after axillary clearance in the treatment of breast cancer.

PMID- 29593864 TI - Laparoscopic abdominoperineal resection for the treatment of a mucinous adenocarcinoma associated with an anal fistula. AB - Mucinous adenocarcinoma associated with an anal fistula is a rare oncologic entity which may pose diagnostic and therapeutic challenges for Surgeons and Medical Oncologists. Few reported cases without definite therapeutic guidelines exist. It represents 2-3% of all gastrointestinal malignancies and arises from chronic anal fistulas, ischiorectal or perianal abscesses. We report a case of perianal mucinous adenocarcinoma in a 65-year-old male initially surgically treated multiple times for a recurrent fistula in ano of 5 years duration. He presented with an ischiorectal and a perianal fistula. Incisional biopsy from fistulotomy revealed mucinous adenocarcinoma. Contrast enhanced computed tomography scan and magnetic resonance imaging showed a localized perianal growth of a tumor which was further evaluated with colonoscopy. With no evidence of metastasis, we performed a laparoscopic abdominoperineal resection (APR). Two years follow-up after APR and without adjuvant chemotherapy there is not any evidence of recurrence or distant metastasis.

PMID- 29593866 TI - A rare case of giant extra-ovarian mucinous cystadenoma arising from sigmoid mesocolon. AB - An 80-year-old female presented with one month history of acutely worsening abdominal distention and pain, without features of bowel obstruction. A giant intra-abdominal simple cyst, separate from the ovaries, was seen on imaging. Initial haematological and biochemical investigations, including tumour markers, were normal. At laparotomy, the cystic tumour was discovered to arise from the sigmoid mesocolon and was resected en bloc. Histopathology revealed the tumour to be a benign extra-ovarian mucinous cystadenoma, which is a neoplasm of ovarian origin that can arise from extra-ovarian sites, including the mesentery. Extra ovarian mucinous cystadenoma arising specifically from the mesentery are very rare intra-abdominal neoplasms with malignant potential despite its benign appearance on investigations. This case aims to raise awareness of this condition and to highlight its diagnostic approach and surgical management. PMID- 29593867 TI - Joint hierarchical Gaussian process model with application to personalized prediction in medical monitoring. AB - A two-level Gaussian process (GP) joint model is proposed to improve personalized prediction of medical monitoring data. The proposed model is applied to jointly analyze multiple longitudinal biomedical outcomes, including continuous measurements and binary outcomes, to achieve better prediction in disease progression. At the population level of the hierarchy, two independent GPs are used to capture the nonlinear trends in both the continuous biomedical marker and the binary outcome, respectively; at the individual level, a third GP, which is shared by the longitudinal measurement model and the longitudinal binary model, induces the correlation between these two model components and strengthens information borrowing across individuals. The proposed model is particularly advantageous in personalized prediction. It is applied to the motivating clinical data on cystic fibrosis disease progression, for which lung function measurements and onset of acute respiratory events are monitored jointly throughout each patient's clinical course. The results from both the simulation studies and the cystic fibrosis data application suggest that the inclusion of the shared individual-level GPs under the joint model framework leads to important improvements in personalized disease progression prediction. PMID- 29593868 TI - Recommendations for active correction of hypernatremia in volume-resuscitated shock or sepsis patients should be taken with a grain of salt: A systematic review. AB - Background: Healthcare-acquired hypernatremia (serum sodium >145 mEq/dL) is common among critically ill and other hospitalized patients and is usually treated with hypotonic fluid and/or diuretics to correct a "free water deficit." However, many hypernatremic patients are eu- or hypervolemic, and an evolving body of literature emphasizes the importance of rapidly returning critically ill patients to a neutral fluid balance after resuscitation. Objective: We searched for any randomized- or observational-controlled studies evaluating the impact of active interventions intended to correct hypernatremia to eunatremia on any outcome in volume-resuscitated patients with shock and/or sepsis. Data sources: We performed a systematic literature search with studies identified by searching MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, ClinicalTrials.gov, Index-Catalogue of the Library of the Surgeon General's Office, DARE (Database of Reviews of Effects), and CINAHL and scanning reference lists of relevant articles with abstracts published in English. Data synthesis: We found no randomized- or observational controlled trials measuring the impact of active correction of hypernatremia on any outcome in resuscitated patients. Conclusion: Recommendations for active correction of hypernatremia in resuscitated patients with sepsis or shock are unsupported by clinical research acceptable by modern evidence standards. PMID- 29593869 TI - Do post-reproductive aged females promote maternal health? Preliminary evidence from historical populations. AB - Background and Objectives: Much literature argues that natural selection conserved menopause and longevity in women because those who stopped childbearing helped bolster daughters' fertility and reduce infant mortality among grandchildren. Whether the presence of grandmothers ever improved fitness sufficiently to affect longevity via natural selection remains controversial and difficult to test. The argument underlying the grandmother and associated alloparenting literature, however, leads us to the novel and testable prediction that the presence of older women in historical societies could have affected population health by reducing lethality associated with childbearing. Methodology: Using historical life table data from four societies (Denmark, England and Wales, France and Sweden), we test the hypothesis that death rates among women initiating childbearing declined when the societies in which they were embedded included unexpectedly high frequencies of older women. We use time series analysis to measure the extent to which the observed likelihood of death among women aged 20-24 differs from statistically expected values when the number of older women grows or declines. Results: In three of the four countries examined, we find an inverse relationship between the frequency of post reproductive females in the population and odds of mortality among females at the peak of childbearing initiation. Conclusions and Implications: Results suggest that the presence of older women in a population may enhance population health by reducing mortality among women who face high risk of maternal death, although additional research is needed to determine if this relationship is causal. PMID- 29593870 TI - Childhood food allergies: An evolutionary mismatch hypothesis. AB - For hominins living in the Paleolithic era, early food antigen exposures-in utero and throughout infancy-closely matched later exposures, and therefore immune system tolerance mechanisms evolved under the expectation of this condition being met. This predicts that the degree of mismatch between early and downstream food antigen exposures is a key variable underlying the development of childhood food allergies. Three historical periods are identified in which the degree of mismatch climbs from near zero to substantial, as we transition from one period to another. The first encompasses our long history as foragers; the second begins with the advent of farming and the third spans only the most recent two or three decades, and manifests from social changes driven largely by an explosion in access to information. Testable predictions are generated and evaluated in light of available evidence, and an approach for primary prevention of childhood food allergies is proposed. PMID- 29593871 TI - Impact of motorboats on fish embryos depends on engine type. AB - Human generated noise is changing the natural underwater soundscapes worldwide. The most pervasive sources of underwater anthropogenic noise are motorboats, which have been found to negatively affect several aspects of fish biology. However, few studies have examined the effects of noise on early life stages, especially the embryonic stage, despite embryo health being critical to larval survival and recruitment. Here, we used a novel setup to monitor heart rates of embryos from the staghorn damselfish (Amblyglyphidodon curacao) in shallow reef conditions, allowing us to examine the effects of in situ boat noise in context with real-world exposure. We found that the heart rate of embryos increased in the presence of boat noise, which can be associated with the stress response. Additionally, we found 2-stroke outboard-powered boats had more than twice the effect on embryo heart rates than did 4-stroke powered boats, showing an increase in mean individual heart rate of 1.9% and 4.6%, respectively. To our knowledge this is the first evidence suggesting boat noise elicits a stress response in fish embryo and highlights the need to explore the ecological ramifications of boat noise stress during the embryo stage. Also, knowing the response of marine organisms caused by the sound emissions of particular engine types provides an important tool for reef managers to mitigate noise pollution.

AB - Post-transplant lymphoproliferative disorder (PTLD) occurs in ~5% of solid organ and hematopoietic stem cell transplant recipients. We report a unique presentation of PTLD in the bladder of a lung transplant recipient. Our patient was a 62-year-old female who received a bilateral lung transplant for chronic obstructive pulmonary disease. She presented with fever, left-sided flank pain and foul-smelling urine consistent with urosepsis. An abdominal and pelvic computerized tomography revealed an irregular and nodular bladder wall thickening suspicious for urothelial neoplasm. Cystoscopy revealed multiple bladder masses and biopsy demonstrated non-Hodgkin lymphoma consistent with PTLD. She was treated with a reduction in immunosuppression followed by chemotherapy and achieved remission. PTLD in the lung transplant recipients has been described in the gut, respiratory tract, skin, liver and kidney but not in the bladder. This case highlights the need for maintaining a high clinical vigilance even when transplant recipients present with seemingly benign clinical complaints. PMID- 29593874 TI - Statin-induced rhabdomyolysis: a complication of a commonly overlooked drug interaction. AB - Rhabdomyolysis is a well-documented side effect of statin therapy. This risk is increased with concurrent use of medications that inhibit cytochrome p450-3A4 (CYP3A4), such as macrolide antibiotics. We present the case of a 67-year-old patient who was commenced on clarithromycin on a background of simvastatin therapy, resulting in rhabdomyolysis. This case highlights the need for awareness of common drug interactions associated with statins. It also emphasizes the significance of commencing statins at a lower dose in new patients, and lastly, the importance of early recognition and management of rhabdomyolysis to prevent the development of complications. PMID- 29593875 TI - Long-term, low-dose of clarithromycin as a cause of community-acquired Clostridium difficile infection in a 5-year-old boy. AB - Clostridium difficile is one of the most common causes of antibiotic-associated diarrhoea. Despite C. difficile infection (CDI) has increased in all ages worldwide, episodes of CDI are often misdiagnosed due to the lack of clinical suspicion. Macrolides are also associated with CDI. Additionally, exposure to macrolides in the 12 weeks preceding infection is reported to be a significant risk factor of CDI in a child. We report here a 5-year-old Japanese boy who presented with acute onset of watery diarrhoea. He was diagnosed with community acquired CDI induced by long-term (20 weeks), low-dose, oral clarithromycin for otitis media with effusion, and he recovered by conservative treatment. Physicians should be more cautious of community-acquired CDI in children who take long-term, low-dose macrolides, not to misdiagnose as diarrhoea by its side effect, and avoid unnecessary use of systemic antibiotics.

Patients with HHT may present with a wide spectrum of clinical manifestations, some considered to be life-threatening. We present the case of a 53-year-old male who presented with massive haemoptysis. Chest computed tomography scan was remarkable for a large anterior, left lower lobe arteriovenous malformation. The patient underwent a pulmonary angiogram with embolization of a large left lung arteriovenous malformation, which proved to be successful in controlling the bleeding. PMID- 29593877 TI - Refractory hyperparathyroidism with a T3 bony lesion-differential diagnoses. AB - We report a case of severe hyperparathyroidism complicated by osteitis fibrosa cystica in an 83-year-old man post-myocardial infarction. The lesions were evident on magnetic resonance imaging only. A diagnosis of parathyroid carcinoma was considered due to clinical appearance of the parathyroid intraoperatively and the presence of an invasive T3 lesion mimicking metastatic disease. Differentiating parathyroid carcinoma from the benign causes at presentation can be difficult due to overlapping clinical, biochemical, radiological and histological features. The presence of bony lesions increases the diagnostic complexity of the case and demonstrates the challenges involved in the management of this disorder. PMID- 29593878 TI - Methicillin-resistant Staphylococcus aureus prostatic abscess after traumatic rectal injury. AB - Methicillin-resistant Staphylococcus aureus (MRSA) commonly causes infection of the skin, soft tissue, bones and heart. MRSA is a rarely reported organism of prostatic abscess (PA). We present a case of an intravenous drug user who presented with dyspareunia, dysuria and dyschezia after a traumatic injury to the rectum. He was diagnosed with PA, which was treated with transurethral resection of the prostate drainage and intravenous antibiotics. MRSA PA carries a low case fatality rate on early diagnosis and treatment with proper antibiotics with or without drainage of the abscess. PMID- 29593879 TI - The Role of Desmopressin in the Management of Severe, Hypovolemic Hyponatremia: A Single-Center, Comparative Analysis. AB - Background: The role of desmopressin (DDAVP) to prevent or treat rapid serum sodium concentration ([Na]s) correction during hyponatremia management remains unclear. Objective: To assess DDAVP use during the first 48 hours of severe, hypovolemic hyponatremia management. The primary study hypothesis was that the use of DDAVP would slow the rate of [Na]s correction compared with those not receiving DDAVP. Design: A retrospective, observational, comparison study. Setting: A single, Canadian, tertiary center. Patients: All admitted patients referred to the nephrology service for severe, hypovolemic hyponatremia ([Na]s < 125 mmol/L) over a 12-month period from November 2015. Measurements: The primary outcomes measure was the [Na]s after medical management for 48 hours. The length of hospital stay was also measured. Methods: Patients were grouped based on whether they received DDAVP during the first 48 hours of treatment, and [Na]s correction was compared between groups using linear regression. An exploratory, multivariable, linear regression model was used to adjust for diabetes status, active malignancy, intensive care unit (ICU) admission, and hypertonic saline administration. Results: Twenty-eight patients were identified, with baseline mean [Na]s of 112.7 +/- 6.6 mmol/L versus 117 +/- 4.3mmol/L (P = .06) in those receiving (n = 16) and not receiving DDAVP (n = 12), respectively. The DDAVP group had a more rapid [Na]s correction on the first day compared with those not receiving DDAVP, 7.7 +/- 3.8 mmol/L/d versus 5.1 +/- 2.0 mmol/L/d (P = .04). On the second day, there was a similar rate of [Na]s correction between groups: 1.3 +/- 4.3 mmol/L/d versus 2.6 +/- 3.2 mmol/L/d (P = .39), respectively. Overall, there was no difference in [Na]s correction after 48 hours between those who received DDAVP and those who did not: 121.7 +/- 7.5 mmol/L versus 124.8 +/- 5.7 mmol/L (P = .24). Patients who had experienced an overcorrection were successfully treated with DDAVP (n = 5), so that no patient had an ongoing overcorrection by 48 hours. Limitations: The limited sample size and lack of randomization preclude definitive conclusion on the additional benefit of DDAVP to standard care. Conclusion: DDAVP appears to be safe and effective in the management of severe, hypovolemic hyponatremia, associated with similar [Na]s correction to those who did not receive DDAVP after 48 hours, despite an initial more rapid correction. A randomized trial should examine what benefit DDAVP confers in addition to standard care in the management of severe, hypovolemic hyponatremia. PMID- 29593880 TI - Atrophy of the putamen at time of clinical motor onset in Huntington's disease: a 6-year follow-up study. AB - Background: Striatal atrophy is detectable many years before the predicted onset of motor symptoms in premanifest Huntington's disease (HD). However, the extent of these neurodegenerative changes at the actual time of conversion from premanifest to a motor manifest disease stage is not known. With this study, we aimed to assess differences in degree and rate of atrophy between converters, i.e. premanifest individuals who develop clinically manifest HD over the course of the study, and non-converters. Methods: Structural T1-weighted Magnetic Resonance Imaging (MRI) scans were used to measure volumes of seven subcortical structures. Images were acquired yearly over a maximum follow-up period of 6 years (mean 4.8 +/- 1.8 years) in 57 participants (healthy controls n = 28, premanifest HD gene carriers n = 29). Of the premanifest HD gene carriers, 20 individuals clinically developed manifest HD over the course of the study, i.e. converters, whereas 9 individuals did not show any clinical signs. Differences between controls, converters and non-converters in volumetric decline over time were assessed using a one-way ANCOVA with age, gender and intracranial volume as covariates. All data were adjusted for multiple comparisons using Bonferonni correction. Results: The putamen showed a significant difference in volume at the time of conversion in the converters group compared to the non-converters group (adjusted p = 0.04). Although, volumes of all other subcortical structures were smaller at time of conversion compared to non-converters and controls, these differences were not statistically significant. Over time, rate of volumetric decline in all subcortical structures in converters did not significantly differ from non-converters. Conclusions: Putamen volume is smaller at the time of manifestation of motor symptoms compared with premanifest HD that not showed any clinical disease progression during the course of this 6-year follow-up study. PMID- 29593881 TI - Clinical characteristics and patient-reported outcomes in patients with inadequately controlled rheumatoid arthritis despite ongoing treatment. AB - Background: Despite the wide array of treatments available for rheumatoid arthritis (RA), some patients continue to report unmet clinical needs. We investigated the extent of inadequate disease control in patients with RA. Methods: Data were drawn from the Adelphi 2014 RA Disease-Specific Program in France, Germany, Italy, Spain and the UK. Rheumatologists provided patient demographics, comorbidities, satisfaction with RA control and other clinical details. Patients reported their level of satisfaction and completed the EuroQoL 5-Dimensions Health Questionnaire and Work Productivity and Activity Impairment Questionnaire. Patients had been on their current therapy >=3 months and had 28 joint disease activity scores (DAS28) reported. Adequately controlled (DAS28 <=3.2) and inadequately controlled (DAS28 >3.2) patient cohorts were compared using univariate tests. Results: Of 1147 patients, 74% were women, the mean age was 52 years and the mean time since RA diagnosis was 7 years. Twenty-seven percent of patients had inadequately controlled RA, whereas 73% had adequately controlled RA. Inadequately controlled patients were more affected clinically versus adequately controlled patients; 69% vs 13% had moderate/severe RA, the current level of pain was 4.6 vs 2.3, and 67% vs 41% experienced flares, respectively (all p<0.0001). Inadequately controlled patients had higher rates of depression (16% vs 5%; p<0.0001), worse health state, greater work and activity impairment, and lower satisfaction rates among the patients and their physicians than the adequately controlled cohort. Conclusion: RA was insufficiently controlled in over a quarter of patients despite their current therapy and this had a negative impact on the patients. PMID- 29593882 TI - Low-fidelity Venezuelan equine encephalitis virus polymerase mutants to improve live-attenuated vaccine safety and efficacy. AB - During RNA virus replication, there is the potential to incorporate mutations that affect virulence or pathogenesis. For live-attenuated vaccines, this has implications for stability, as replication may result in mutations that either restore the wild-type phenotype via reversion or compensate for the attenuating mutations by increasing virulence (pseudoreversion). Recent studies have demonstrated that altering the mutation rate of an RNA virus is an effective attenuation tool. To validate the safety of low-fidelity mutations to increase vaccine attenuation, several mutations in the RNA-dependent RNA-polymerase (RdRp) were tested in the live-attenuated Venezuelan equine encephalitis virus vaccine strain, TC-83. Next generation sequencing after passage in the presence of mutagens revealed a mutant containing three mutations in the RdRp, TC-83 3x, to have decreased replication fidelity, while a second mutant, TC-83 4x displayed no change in fidelity, but shared many phenotypic characteristics with TC-83 3x. Both mutants exhibited increased, albeit inconsistent attenuation in an infant mouse model, as well as increased immunogenicity and complete protection against lethal challenge of an adult murine model compared with the parent TC-83. During serial passaging in a highly permissive model, the mutants increased in virulence but remained less virulent than the parent TC-83. These results suggest that the incorporation of low-fidelity mutations into the RdRp of live-attenuated vaccines for RNA viruses can confer increased immunogenicity whilst showing some evidence of increased attenuation. However, while in theory such constructs may result in more effective vaccines, the instability of the vaccine phenotype decreases the likelihood of this being an effective vaccine strategy.

PMID- 29593883 TI - Qualitative assessment of a Context of Consumption Framework to inform regulation of cigarette pack design in the U.S. AB - INTRODUCTION: Researchers and regulators need to know how changes to cigarette packages can influence population health. We sought to advance research on the role of cigarette packaging by assessing a theory-informed framework from the fields of design and consumer research. The selected Context of Consumption Framework posits cognitive, affective, and behavioral responses to visual design. To assess the Framework's potential for guiding research on the visual design of cigarette packaging in the U.S., this study seeks to understand to what extent the Context of Consumption Framework converges with how adult smokers think and talk about cigarette pack designs. METHODS: Data for this qualitative study came from six telephone-based focus groups conducted in March 2017. Two groups consisted of lesbian, gay, and bisexual participants; two groups of participants with less than four years college education; one group of LGB and straight identity; and one group the general population. All groups were selected for regional, gender, and racial/ethnic diversity. Participants (n=33) represented all nine U.S. Census divisions. We conducted a deductive qualitative analysis. RESULTS: Cigarette package designs captured the participants' attention, suggested the characteristics of the product, and reflected (or could be leveraged to convey) multiple dimensions of consumer identity. Particular to the affective responses to design, our participants shared that cigarette packaging conveyed how the pack could be used to particular ends, created an emotional response to the designs, complied with normative expectations of a cigarette, elicited interest when designs change, and prompted fascination when unique design characteristics are used. CONCLUSIONS: Use of the Context of Consumption Framework for cigarette product packaging design can inform regulatory research on tobacco product packaging. Researchers and regulators should consider multiple cognitive, affective, and behavioral responses to cigarette pack design. PMID- 29593885 TI - High-profile studies frequently and repetitively present data on the same patients, particularly in immunotherapy studies. AB - Background: Traditionally, study results have been presented as abstracts at major scientific meetings at the conclusion of the analysis. Recently, presentations of studies in progress and updates to previously presented data have been allowed at major meetings. The frequency and implications of a single study being presented multiple times, particularly in high profile oral presentations, have not been fully evaluated. Methods: To identify studies presented multiple times, abstracts from an approximately 1-year period from international conferences for three major societies devoted largely or in part to lung cancer research were assessed (ASCO 2015, World Lung 2015, ESMO 2015 and ASCO 2016). Abstracts were selected in a two-step process. The first step was for subject matter based on keywords: non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC) or immunotherapy. Searches differed slightly based on individual website functionality, with ASCO searched by track, World Lung by session and ESMO by individual abstract. In a second step, abstracts for which clinical outcome data was presented from a trial with an identifiable National Clinical Trial (NCT) number were selected. Immunotherapy abstracts that did not include the treatment of NSCLC or SCLC were excluded in the second step. Results: A total of 851 abstracts were identified that were related to NSCLC, SCLC or immunotherapy. Of these, 357 referred to a clinical trial. In total, 110 of 357 (31%) described clinical trials that were presented multiple times (mean 2.75, range 2-7), and in 44 (12%), this occurred at the same conference. Of the 113 oral presentations, 75 (66%) presented data from clinical trials, either as posters or oral presentations. Further, 35 of the 113 (31%) oral presentations presented data from clinical trials that had generated other oral presentations. Of the 16 unique clinical trials leading to multiple oral presentations, a variety of issues led to the duplicate presentations, including different cohorts of the same trial, biomarker analysis, analysis by one study variable, or simply updated data. Moreover, 107 of the 357 (30%) clinical trial abstracts pertained to immunotherapy, including 4 of the 16 clinical trials generating multiple oral presentations. Of the 16 trials generating multiple oral presentations, 11 (69%) lead to a full-length publication by July 2017, including all of those pertaining to immunotherapy. Conclusions: There is a pattern of multiple presentations of clinical trials, particularly in oral presentations, at major meetings. In most cases, data presented in subsequent oral presentations related entirely to patients whose data was presented in the previous oral presentation. PMID- 29593886 TI - Immunotherapy in surgically resectable non-small cell lung cancer. AB - Surgical resection is the mainstay of therapy for patients with resectable and operable early stage non-small cell lung cancer (NSCLC). Surgery alone yields an unacceptably high rate of lung cancer recurrence. The addition of chemotherapy to surgery as adjuvant or neoadjuvant treatment can improve survival rates by roughly 5% at 5 years. Recently, major advances in cancer immunotherapy have led to better outcomes for many patients with lung cancer. Monoclonal antibodies to programmed death 1 and its ligand are now approved for both first and second line treatment patients with metastatic lung cancer. In this review, we will outline the rationale and current research strategies investigating the role of immunotherapy in resectable NSCLC. PMID- 29593887 TI - Immunotherapy in treatment naive advanced non-small cell lung cancer. AB - Lung cancer is the leading cause of cancer-related mortality worldwide. Non-small cell lung cancer (NSCLC) comprises approximately 85% of lung cancers and, unfortunately, more than half of these patients are diagnosed with metastatic disease. Platinum-based chemotherapy has for long been the standard frontline therapy for advanced disease. Despite remarkable advances in targeted therapy for a subset of patients harboring a driver mutation, the prognosis in the majority of the lung cancer population have not changed significantly. More recently, immunotherapy has drastically changed the treatment of NSCLC and have established a new treatment paradigm for these patients. Pembrolizumab is now the new mainstay first-line treatment for those with high-PD-L1 expression. However, many questions remain regarding how to sequence and combine these agents in the frontline setting. The optimal patient selection strategies are also unclear. High PD-L1 expression is associated with higher response rates, but even patients with low or absent PD-L1 expression benefit from these drugs. More recently, tumor mutational burden is been proposed as a potential predictive marker for response. This article will review the data regarding the usage of immunotherapy in treatment naive advanced NSCLC. PMID- 29593888 TI - Immunotherapy in previously treated non-small cell lung cancer (NSCLC). AB - Treatment with immunotherapy has made a significant impact in the outcomes for those individuals diagnosed with metastatic non-small cell lung cancer (NSCLC) and its use is currently an established treatment modality. In light of recent advances in immunotherapy, improved survival, particularly for patients with stage IV NSCLC, has been reported with durable and prolonged responses in a subset of patients. Immune check point inhibitors, which include nivolumab, pembrolizumab, and atezolizumab, are standard treatment options in the salvage setting. Nivolumab and atezolizumab are approved for patients regardless of programmed death-ligand 1 (PD-L1) expression, whereas pembrolizumab requires tumor PD-L1 expression at the cut-off >=1%. In this review, we will outline the clinical development of immunotherapy in previously treated NSCLC, current challenges and discuss novel treatment strategies. PMID- 29593889 TI - Immunotherapy combination strategies (non-chemotherapy) in non-small cell lung cancer. AB - Immune checkpoint inhibitors enhance the activation and antitumor activity of the immune system, resulting in durable response rates in a select group of patients. Cytotoxic T lymphocyte antigen 4 (CTLA4) inhibitors target the inhibitory interaction between CTLA4 and CD80 or CD86. Programmed death 1 (PD1) inhibitors target the interaction between PD1 receptors on T-cells and PD-ligand 1 (PD-L1) and PD-ligand 2, blocking the inhibitory signaling and resulting in activation of T-cell effector function. These therapeutic drugs were originally evaluated in patients with metastatic melanoma before expansion to all tumor types, including non-small cell lung cancer (NSCLC) with promising results. The PD1 inhibitors such as pembrolizumab have now received FDA approval in the first-line setting for patients with positive PD-L1 expression tumor types; however, only a portion of patients have shown objective and sustainable responses. To expand the number of patients with observed response to immunotherapeutic agents including patients with negative PD-L1 expression tumors, clinical trials are ongoing to assess the safety and efficacy of combination immune checkpoint inhibitors and combination immune checkpoint inhibitors with targeted therapy. Immune checkpoint inhibitors have been found to be a promising therapeutic drug class with sustainable response rates and a tolerable safety profile, and efforts continue to improve these drugs in patients with NSCLC. PMID- 29593890 TI - Neoadjuvant and consolidation immuno-oncology therapy in stage III non-small cell lung cancer. AB - Lung cancer continues to be the leading cause of cancer death worldwide. Recently, immunotherapy for non-small cell lung cancer (NSCLC) has emerged as a powerful treatment option for advanced lung cancer. The relative success of programmed death 1 (PD-1) and/or programmed death ligand 1 (PD-L1) antibodies in metastatic disease have increased interest in expanding their use to earlier stage NSCLC. The complex and diverse nature of stage III disease also invites the incorporation of immunotherapy into treatment plans in both the neoadjuvant and consolidation settings. Currently available data of anti-PD-(L)1 therapies in stage III NSCLC are limited. However, interim results from two studies are encouraging: a phase II neoadjuvant nivolumab trial demonstrated early signals of efficacy, and the phase III PACIFIC trial of durvalumab recently showed significant improvement in progression-free survival (PFS). Preliminary results for the phase II DETERRED trial of durvalumab have also been reported. Many studies are testing anti-PD-(L)1 therapies in the neoadjuvant and consolidation settings for stage III NSCLC, and will be discussed. As these studies mature they may provide further treatment options in management of stage III NSCLC. PMID- 29593891 TI - Immune checkpoint inhibitors in small cell lung cancer. AB - Small cell lung cancer (SCLC) is a rapidly progressive cancer that often debilitates patients within months of detection and quickly becomes refractory to the limited options of therapy. While SCLC is not generally considered an immunogenic tumor, clinical experience suggests that patients with robust immune response manifesting as paraneoplastic syndrome are more likely to present with limited stage of the disease and tend to have a better prognosis. Monoclonal antibodies targeting critical negative regulators of immune response, so called immune checkpoints, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed death 1 (PD-1) have expanded the application of immune-based therapies to increasing number of advanced stage cancers. These agents overcome the inhibitory immune signals leading to a heightened immune response against cancer cells. These immune checkpoint inhibitors have established efficacy leading to regulatory approval for their use in many cancer types including non small cell lung cancer (NSCLC). Evaluation of the CTLA-4 inhibitor, ipilimumab and PD-1 inhibitors, nivolumab and pembrolizumab in SCLC have shown encouraging signal but definitive studies are still ongoing. In this review, we discuss the rationale behind the use of checkpoint inhibitors in SCLC, contextualize the results of early trials of immunotherapy agents in SCLC and project the future evolution of this strategy. PMID- 29593892 TI - Combining radiation plus immunotherapy to improve systemic immune response. AB - Over the past decade, the fields of oncology have made great strides in therapies. The development of new therapeutics and increased understanding of the role of the immune system in the development and treatment of cancer has led to increased collaboration between oncologic fields. Recent technologic advancements in radiation therapy (RT), including stereotactic beam radiation therapy (SBRT), have improved local control and offer an alternative to surgery for the control of oligometastatic disease. Immunotherapy has proven a promising therapeutic in the treatment of metastatic disease but treatment resistance remains a significant obstacle in the majority of patients. Together, radiation and immunotherapy offer potential to eliminate metastatic disease, reduce time to recurrence and improve overall survival. Major obstacles to these positive outcomes include high tumor burden, intratumoral heterogeneity, and the negative effects of tumor stroma, to name a few. Multimodality treatments are under heavy investigation. Promising data from clinical trials is emerging to highlight the value of RT in combination with immunotherapy. However, the mechanisms behind their synergistic effects remain to be fully elucidated. This review aims to highlight the existing literature and offers hypotheses to explain mechanisms behind the synergy of RT and immunotherapy. PMID- 29593893 TI - Identifying and managing the adverse effects of immune checkpoint blockade. AB - Immunotherapy has revolutionized the field of oncology. By inhibiting the cytotoxic T-lymphocyte-associated protein (CTLA-4) and programmed death-1 (PD-1) immune checkpoint pathways, multiple studies have demonstrated greatly improved survival in locally advanced and metastatic cancers including melanoma, renal, lung, gastric, and hepatocellular carcinoma. Trials in other malignancies are ongoing, and undoubtedly the number of drugs in this space will grow beyond the six currently approved by the Food and Drug Administration. However, by altering the immune response to fight cancer, a new class of side effects has emerged known as immune-related adverse events (irAEs). These adverse events are due to overactivation of the immune system in almost any organ of the body, and can occur at any point along a patient's treatment course. irAEs such as endocrinopathies (thyroiditis), colitis, and pneumonitis may occur more commonly. However, other organs such as the liver, heart, or brain may also be affected by immune overactivation and any of these side effects may become life threatening. This review presents an approach to promptly recognize and manage these toxicities, to hopefully minimize morbidity and mortality from irAEs. PMID- 29593894 TI - Validation of a Survey Questionnaire on Organ Donation: An Arabic World Scenario. AB - Objective: To validate a questionnaire for measuring factors influencing organ donation and transplant. Methods: The constructed questionnaire was based on the theory of planned behavior by Ajzen Icek and had 45 questions including general inquiry and demographic information. Four experts on the topic, Arabic culture, and the Arabic and English languages established content validity through review. It was quantified by content validity index (CVI). Construct validity was established by principal component analysis (PCA), whereas internal consistency was checked by Cronbach's Alpha and intraclass correlation coefficient (ICC). Statistical analysis was performed by SPSS 22.0 statistical package. Results: Content validity in the form of S-CVI/Average and S-CVI/UA was 0.95 and 0.82, respectively, suggesting adequate relevance content of the questionnaire. Factor analysis indicated that the construct validity for each domain (knowledge, attitudes, beliefs, and intention) was 65%, 71%, 77%, and 70%, respectively. Cronbach's Alpha and ICC coefficients were 0.90, 0.67, 0.75, and 0.74 and 0.82, 0.58, 0.61, and 0.74, respectively, for the domains. Conclusion: The questionnaire consists of 39 items on knowledge, attitudes, beliefs, and intention domains which is valid and reliable tool to use for organ donation and transplant survey. PMID- 29593895 TI - Cross-Sectional Serological Survey of Human Fascioliasis in Canutama Municipality in Western Amazon, Brazil. AB - Background: Fascioliasis is an important parasitic disease. In the northern region of Brazil, a human parasite infection has been reported through a coprological survey. Eggs of Fasciola hepatica were found in fecal samples of 11 individuals. Knowledge of the infection in animals or the presence of snails is necessary to address the possibility of the parasite cycle occurrence in that region. The aim of this study was to describe the transmission of human fascioliasis in Canutama, Amazonas, in Western Amazonia, Brazil. Methods: Serological (ELISA and Western Blot, WB) and parasitological analyses were carried out in humans. In addition, the presence of the intermediate snail host within the community was examined. Results: A total of 434 human samples were included in the study, of which 36 (8.3%) were reactive by ELISA and 8 (1.8%) were reactive by WB. Fasciola hepatica eggs were found in one human sample. The occurrence of the intermediated host was recorded and 31/43 specimens were identified as Lymnaea columella. Conclusion. Canutama constitutes a focus of transmission of human fascioliasis. This study describes the first serological survey for human fascioliasis, as well as its simultaneous occurrence in human hosts and possible intermediates performed in northern Brazil. PMID- 29593896 TI - Enteroparasites in Riverside Settlements in the Pantanal Wetlands Ecosystem. AB - Background: Intestinal parasites are a major source of health problems in developing countries, where socioeconomic, cultural, and environmental conditions contribute in maintaining the biological cycles of various parasites and facilitating their spread. The objective of this study, conducted in Corumba, Mato Grosso do Sul state, Brazil, was to investigate the occurrence of intestinal parasites in riverside communities in the South Pantanal wetlands and conduct educational interventions focused on health and environmental preservation. Method: In total, 196 stool samples were tested for parasites using the merthiolate-iodine-formaldehyde concentration (MIFC) technique and spontaneous sedimentation and educational activities were carried out. Results: Enteroparasite prevalence was 72% (65.6-78.2%; 95% CI). Of the 141 positive cases, monoparasitism was found in 34.7%, biparasitism in 23%, and polyparasitism in 14.3%. Entamoeba coli was the most frequent protozoan (70.2%). Among helminths, hookworms were the most prevalent. Enteroparasitosis prevalence did not differ for sex or place of abode but proved higher in individuals older than 10 years. Conclusion: The high positivity rate for enteroparasites found for the communities stems from lack of sanitation and poor personal and environmental hygiene habits, indicating that effective health policies and educational interventions are needed to reduce the current risk levels. PMID- 29593897 TI - Serum Presepsin Levels Are Not Elevated in Patients with Controlled Hypertension. AB - Introduction: Hypertension (HT) is a common serious condition associated with cardiovascular morbidity and mortality. The pathogenesis of HT is multifactorial and has been widely investigated. Besides the vascular, hormonal, and neurological factors, inflammation plays a crucial role in HT. Many inflammatory markers such as C-reactive protein, cytokines, and adhesion molecules have been studied in HT, which supported the role of inflammation in the pathogenesis of HT. Presepsin (PSP) is a novel biomarker of inflammation. Therefore, the potential relationship between PSP and HT was investigated in this study. Methods: Forty-eight patients with controlled HT and 48 controls without HT were included in our study. Besides routine clinical and laboratory data, PSP levels were measured in peripheral venous blood samples from all the participants. Results: PSP levels were significantly lower in patients with HT than in controls (144.98 +/- 75.98 versus 176.67 +/- 48.12 pg/mL, p = 0.011). PSP levels were positively correlated with hsCRP among both the patient and the control groups (p = 0.015 and p = 0.009, resp.). However, PSP levels were not correlated with WBC among both groups (p = 0.09 and p = 0.67, resp.). Conclusions: PSP levels are not elevated in patients with well-controlled HT compared to controls. This result may be associated with anti-inflammatory effects of antihypertensive medicines. PMID- 29593898 TI - Role of Mast Cells in Oral Lichen Planus and Oral Lichenoid Reactions. AB - Introduction: Oral lichen planus (OLP) is a chronic T cell mediated disease of oral mucosa, skin, and its appendages with a prevalence of 0.5 to 2.6% worldwide. Oral lichenoid reactions (OLR) are a group of lesions with diverse aetiologies but have clinical and histological features similar to OLP, thereby posing a great challenge in differentiating both lesions. Mast cells are multifunctional immune cells that play a major role in the pathogenesis of lichen planus by release of certain chemical mediators. Increased mast cell densities with significant percentage of degranulation have been observed as a consistent finding in pathogenesis of oral lichen planus. Aim: The current study was aimed at quantifying the mast cells in histopathological sections of OLP and OLR thereby aiding a means of distinguishing these lesions. Materials and Methods: The study group involved 21 cases of oral lichen planus, 21 cases of oral lichenoid reactions, and 10 control specimens of normal buccal mucosa. All the cases were stained with Toluidine Blue and routine haematoxylin and eosin and the mast cells were quantified. Statistical Analysis Used: The results were analyzed using the Kruskal-Wallis test and an intergroup analysis was performed using Mann Whitney U test. Conclusion: The number of mast cells showed an increased value in oral lichen planus when compared to oral lichenoid reaction and thus an estimation of mast cells count could aid in distinguishing OLP from OLR histopathologically. PMID- 29593899 TI - Feasibility and Safety of Bariatric Surgery in High-Risk Patients: A Single Center Experience. AB - Introduction: Despite the feasibility and safety of bariatric procedures nowadays, high-risk patients with vast obesity and severe comorbidities demonstrate relatively high perioperative morbidity and mortality rates and, therefore, form a distinguished challenge for the bariatric surgeons. Methods: We retrospectively analyzed high-risk patients, who underwent bariatric surgery in University Hospital Leipzig between May 2012 and December 2016. High-risk patients were defined when (Bergeat et al., 2016) at least one of the following risk factors was met: age >= 70 years, body mass index (BMI) > 70 kg/m2, liver cirrhosis, end-organ failure, or immunosuppression by status after organ transplantation along with (Birkmeyer et al., 2010) at least two comorbidities associated with obesity. Our analysis included early postoperative complications. Results: A total of 25 high-risk obese patients were identified. All patients had a standardized postoperative management with a mean length of hospital stay of 4 +/- 1.4 days. One patient required an operative revision due to a stapler line leak after sleeve gastrectomy. No other major postoperative complications occurred. Conclusion: Bariatric surgery for severe high-risk patients can be performed safely in high-volume centers following standardized procedures. PMID- 29593900 TI - The Palatability of Lopinavir and Ritonavir Delivered by an Innovative Freeze Dried Fast-Dissolving Tablet Formulation. AB - Negative hedonic sensory qualities of HIV antiretroviral drugs often reduce patient adherence particularly in pediatric populations requiring oral consumption. This study examines the palatability of an innovative delivery mechanism utilizing a freeze-drying-in-blister approach to create fast-dissolving tablets (FDTs) containing a fixed-dose combination of lopinavir and ritonavir (LPV/r). Consumption patterns of solutions during brief-access and long-term testing and baby foodstuff consumption were analyzed to evaluate the orosensory detection and avoidance of placebo FDTs containing no LPV/r (FDT-) and FDTs containing LPV/r (FDT+). Rats showed no change in consumption patterns for the placebo FDT- compared with control solutions. Rats can detect but do not avoid FDT+ at body-weight-adjusted dosages in both brief-access (30-s) and long-term (23 h) consumption tests. There is an aversive response to concentrated doses of FDT+ during brief-access tests that cannot be masked by 25% sucrose. However, the strongest FDT+ concentration was not rejected when mixed with 50 g of applesauce, banana sauce, or rice cereal baby foodstuffs. The averseness of the FDT+ was associated with the presence of LPV/r and not the FDT- formulation itself. The novel FDT formulation appears to be a palatable delivery mechanism for oral antiretroviral pharmaceuticals especially when mixed with baby foodstuffs. PMID- 29593901 TI - Frequent Benign, Nontraumatic, Noninflammatory Causes of Low Back Pain in Adolescents: MRI Findings. AB - Introduction: Low back pain (LBP) is common in children and adolescents. There are many factors that cause LBP, including structural disorders, degenerative changes, Scheuermann's disease, fractures, inflammation, and tumors. Magnetic Resonance Imaging is the gold standard for diagnosing spinal abnormalities and is mandatory when neurological symptoms exist. The study focuses on common MRI findings in adolescents with persistent LBP, without history of acute trauma or evidence of either inflammatory or rheumatic disease. Materials and Methods: Eleven adolescents were submitted to thoracic and/or lumbar spine MRI due to persistent LBP. The protocol consisted of T1 WI, T2 WI, and T2 WI with FS, in the axial, sagittal, and coronal plane. Results: MRI revealed structural abnormalities (scoliosis and kyphosis) in 4/11 (36.36%); disc abnormalities and endplate changes were found on 11/11 (100%). Typical Scheuermann's disease was found in 3/11 (27.27%). Endplate changes were severe in Scheuermann's patients and mild to moderate in the remaining 8/11 (72.72%). Kyphosis was in all cases secondary to Scheuermann's disease. Disk bulges and hernias were found in 8/11 (72.72%), all located in the lumbar spine. Conclusion: In adolescents with LBP, structural spinal disorders, degenerative changes, and Scheuermann's disease are commonly found on MRI; however, degenerative changes prevail. PMID- 29593902 TI - Confidence amongst Multidisciplinary Professionals in Managing Paediatric Rheumatic Disease in Australia. AB - Objective: Interprofessional collaboration is a crucial component of care for children with rheumatic disease. Interprofessional care, when delivered appropriately, prevents disability and improves long-term prognosis in this vulnerable group. Methods: The aim of this survey was to explore allied health professionals' and nurses' confidence in treating paediatric rheumatology patients. Results: Overall, 117 participants were recruited, 77.9% of participants reported being "not confident at all," "not confident," or "neutral" in treating children with rheumatic diseases (RD) despite 65.1% of participants reporting having treated >1 paediatric rheumatology case in the past month. Furthermore, 67.2% of participants felt their undergraduate education in paediatric rheumatology was inadequate. "Journals" or "texts books" were used by 49.3% of participants as their primary source of continuing professional development (CPD) and 39.3% of participants indicated that they did not undertake any CPD related to paediatric rheumatology. Small group and online education were perceived to be potentially of "great benefit" for CPD. Conclusion: This paper highlights allied health professionals' and nurses' perceived inadequacy of their undergraduate education in paediatric RD and their low confidence in recognising and treating RD. Undergraduate and postgraduate education opportunities focusing on interprofessional collaboration should be developed to address this workforce deficiency. PMID- 29593903 TI - A Possible Link between Anxiety and Schizophrenia and a Possible Role of Anhedonia. AB - In the prodromal phase of schizophrenia, severe alterations of the visual appearance of the environment have been found, accompanied by a state of intense anxiety. The present study considers the possibility that these alterations really exist in the appearance of objects, but that healthy people do not see them. The image of the world that we see is continuously deformed and fragmented by foreshortenings, partial overlapping, and so on and must be constantly reassembled and interpreted; otherwise, it could change so much that we would hardly recognize it. Since pleasure has been found to be involved in visual and cognitive information processing, the possibility is considered that anhedonia (the reduction of the ability to feel pleasure) might interfere with the correct reconstruction and interpretation of the image of the environment and alter its appearance. The possibility is also considered that these alterations might make the environment hostile, might at times evoke the sensation of being trapped by a predator, and might be the cause of the anxiety that accompanies them. According to some authors, they might also induce delusional ideas, in an attempt to restore meaning in a world that has become chaotic and frightening. PMID- 29593904 TI - Self-Rated Health Trajectories among Married Americans: Do Disparities Persist over 20 Years? AB - The purpose of this study is to understand self-rated health (SRH) trajectories by social location (race/ethnicity by gender by social class) among married individuals in the United States. We estimate multilevel models of SRH using six observations from 1980 to 2000 from a nationally representative panel of married individuals initially aged 25-55 (Marital Instability Over the Life Course Study). Results indicate that gender, race/ethnicity, and social class are associated with initial SRH disparities. Women are less healthy than men; people of color are less healthy than whites; lower educated individuals are less healthy than higher educated individuals. Women's health declined slower than men's but did not differ by race/ethnicity or education. Results from complex intersectional models show that white men with any college had the highest initial SRH. Only women with any college had significantly slower declines in SRH compared to white men with any college. For married individuals of all ages, most initial SRH disparities persist over twenty years. Intersecting statuses show that education provides uneven health benefits across racial/ethnic and gender subgroups. PMID- 29593905 TI - Conceptions of Healthy Aging Held by Relatives of Older Persons in Isan-Thai Culture: A Phenomenographic Study. AB - In Thailand, family nurses are expected to provide support for older persons and their family members to promote healthy aging. Family bonds are strong, and relatives are expected to take care of their older family members. However, there is limited research on how older persons' family members perceive healthy aging. This study aimed to describe the conceptions of healthy aging held by the children and grandchildren of older persons in northeast Thailand. In a phenomenographic study, 14 interviews were performed to qualitatively analyze different conceptions of healthy aging. Four descriptive categories emerged: being independent, not being afflicted by diseases or illnesses, being a giver and a receiver, and being wise. The conceptions of healthy aging entail both autonomy and interdependence. The relative's perspective needs to be considered when policies relating to healthy aging are implemented in the community and when family nurses provide support to families to promote healthy aging. PMID- 29593906 TI - Estimating Long-Term Care Costs among Thai Elderly: A Phichit Province Case Study. AB - Background: Rural-urban inequality in long-term care (LTC) services has been increasing alongside rapid socioeconomic development. This study estimates the average spending on LTC services and identifies the factors that influence the use and cost of LTC for the elderly living in urban and rural areas of Thailand. Methods: The sample comprised 837 elderly aged 60 years drawn from rural and urban areas in Phichit Province. Costs were assessed over a 1-month period. Direct costs of caregiving and indirect costs (opportunity cost method) were analyzed. Binary logistic regression was performed to determine which factors affected LTC costs. Results: The total annual LTC spending for rural and urban residents was on average USD 7,285 and USD 7,280.6, respectively. Formal care and informal care comprise the largest share of payments. There was a significant association between rural residents and costs for informal care, day/night care, and home renovation. Conclusions: Even though total LTC expenditures do not seem to vary significantly across rural and urban areas, the fundamental differences between areas need to be recognized. Reorganizing country delivery systems and finding a balance between formal and informal care are alternative solutions. PMID- 29593907 TI - Effects of a 12-Week Exercise Training Program on Physical Function in Institutionalized Frail Elderly. AB - With the increase in life expectancy, the Brazilian elderly population has risen considerably. However, longevity is usually accompanied by problems such as the loss of functional capacity, cognitive decline, frailty syndrome, and deterioration in anthropometric parameters, particularly among those living in long-term care facilities. This randomized controlled trial aimed to verify the effects of exercise training on biochemical, inflammatory, and anthropometric indices and functional performance in institutionalized frail elderly. The sample consisted of 37 elderly people of both genders, aged 76.1 +/- 7.7 years, who were randomly allocated into 2 groups: 13 individuals in the exercise group (EG) and 24 in the control group (CG). Anthropometrics, clinical history, functional tests, and biochemical evaluation were measured before and after the completion of a physical exercise program, which lasted for 12 weeks. The 12-week exercise program for frail elderly residents in a long-term care facility was efficient in improving muscle strength, speed, agility, and biochemical variables, with reversal of the frailty condition in a considerable number. However, no effects in anthropometric and inflammatory parameters were noted. PMID- 29593909 TI - Qualitative Analysis of Primary Fingerprint Pattern in Different Blood Group and Gender in Nepalese. AB - Dermatoglyphics, the study of epidermal ridges on palm, sole, and digits, is considered as most effective and reliable evidence of identification. The fingerprints were studied in 300 Nepalese of known blood groups of different ages and classified into primary patterns and then analyzed statistically. In both sexes, incidence of loops was highest in ABO blood group and Rh +ve blood types, followed by whorls and arches, while the incidence of whorls was highest followed by loops and arches in Rh -ve blood types. Loops were higher in all blood groups except "A -ve" and "B -ve" where whorls were predominant. The fingerprint pattern in Rh blood types of blood group "A" was statistically significant while in others it was insignificant. In middle and little finger, loops were higher whereas in ring finger whorls were higher in all blood groups. Whorls were higher in thumb and index finger except in blood group "O" where loops were predominant. This study concludes that distribution of primary pattern of fingerprint is not related to gender and blood group but is related to individual digits. PMID- 29593908 TI - Can Driving-Simulator Training Enhance Visual Attention, Cognition, and Physical Functioning in Older Adults? AB - Virtual reality offers a good possibility for the implementation of real-life tasks in a laboratory-based training or testing scenario. Thus, a computerized training in a driving simulator offers an ecological valid training approach. Visual attention had an influence on driving performance, so we used the reverse approach to test the influence of a driving training on visual attention and executive functions. Thirty-seven healthy older participants (mean age: 71.46 +/- 4.09; gender: 17 men and 20 women) took part in our controlled experimental study. We examined transfer effects from a four-week driving training (three times per week) on visual attention, executive function, and motor skill. Effects were analyzed using an analysis of variance with repeated measurements. Therefore, main factors were group and time to show training-related benefits of our intervention. Results revealed improvements for the intervention group in divided visual attention; however, there were benefits neither in the other cognitive domains nor in the additional motor task. Thus, there are no broad training-induced transfer effects from such an ecologically valid training regime. This lack of findings could be addressed to insufficient training intensities or a participant-induced bias following the cancelled randomization process. PMID- 29593910 TI - Patients' and Health Professionals' Experiences of Using Virtual Reality Technology for Upper Limb Training after Stroke: A Qualitative Substudy. AB - Background: In recent years, virtual reality (VR) therapy systems for upper limb training after stroke have been increasingly used in clinical practice. Therapy systems employing VR technology can enhance the intensity of training and can also boost patients' motivation by adding a playful element to therapy. However, reports on user experiences are still scarce. Methods: A qualitative investigation of patients' and therapists' perspectives on VR upper limb training. Semistructured face-to-face interviews were conducted with six patients in the final week of the VR intervention. Therapists participated in two focus group interviews after the completion of the intervention. The interviews were analyzed from a phenomenological perspective emphasizing the participants' perceptions and interpretations. Results: Five key themes were identified from the patients' perspectives: (i) motivational factors, (ii) engagement, (iii) perceived improvements, (iv) individualization, and (v) device malfunction. The health professionals described the same themes as the patients but less positively, emphasizing negative technical challenges. Conclusion: Patients and therapists mainly valued the intensive and motivational character of VR training. The playful nature of the training appeared to have a significant influence on the patients' moods and engagement and seemed to promote a "gung-ho" spirit, so they felt that they could perform more repetitions. PMID- 29593911 TI - First Report of blaCTX-M-28 in Enterobacteriaceae Isolates in the United Arab Emirates. AB - Background: The CTX-M family of extended-spectrum beta lactamase (ESBL) enzymes is comprised of over 60 blaCTX-M gene variants with the predominance of blaCTX-M 15 in many regions. In this report, we present the first description of blaCTX-M 28 in the United Arab Emirates. Methods: Forty-five non-duplicate ESBL producing isolates identified in a secondary care facility in the United Arab Emirates from June to July 2016 were studied. Gene sequencing was performed and DNA sequences were annotated using the BLAST program to identify the gene subtypes. Results: The majority of the ESBL positive isolates were E. coli (n/N = 39/45; 86.6%) followed by K. pneumoniae (n = 5) and K. oxytoca (n = 1). All isolates harboured blaCTX-M and blaTEM genes, 18 had blaSHV, and 2 were blaVIM positive. Thirty seven isolates (82.2%) were positive for blaCTX-M-28. Other blaCTX-M genes identified include blaCTX-M-167 (n = 2; isolates #1 and 26) and one each for blaCTX-M-38, blaCTX-M-163, and blaCTX-M-198. No blaCTX-M-15 was identified. The predominant blaTEM subtype was blaTEM-171 (n = 8) followed by one of each of blaTEM-120, blaTEM-163, and blaTEM-206. The blaSHV subtypes were blaSHV-148 and blaSHV-187. Conclusion: The findings indicate the first description of blaCTX-M 28 in a setting where blaCTX-M-15 was previously predominant. PMID- 29593912 TI - Antimicrobial Susceptibility among Colistin, Sulbactam, and Fosfomycin and a Synergism Study of Colistin in Combination with Sulbactam or Fosfomycin against Clinical Isolates of Carbapenem-Resistant Acinetobacter baumannii. AB - This in vitro study aimed to determine the activity of colistin plus sulbactam and colistin plus fosfomycin against carbapenem-resistant A. baumannii (CRAB). Fifteen clinical isolates were obtained from patients admitted to Phyathai II International Hospital, Bangkok, Thailand, from August 2014 to April 2015. The antimicrobial susceptibilities of colistin, sulbactam, and fosfomycin were evaluated using the E-test or broth microdilution and the synergistic activity of the antibacterial combinations (colistin plus sulbactam or fosfomycin) was determined using the chequerboard method. Clonal relationships were explored using repetitive element palindromic- (REP-) PCR. The CRAB isolates were categorized by REP-PCR in 8 groups [A-H]. All CRAB isolates were universally susceptible to colistin but only 20.0% were susceptible to sulbactam. The MIC ranges for colistin, sulbactam, and fosfomycin were 0.75-2 mg/L, 2-96 mg/L, and 64-256 mg/L, respectively. A chequerboard assay revealed that the rates of synergistic and additive effect rates of colistin plus sulbactam and colistin plus fosfomycin were 53.3% and 73.3% of isolates, respectively. No antagonistic effect in any colistin-based combination was observed. However, almost CRAB strains in clone A showed the synergy or additive effects of colistin-sulbactam combination, whereas the other clone (B-H) mostly showed indifferent effects. In conclusion, colistin plus sulbactam and colistin plus fosfomycin against CRAB seem to be interesting option but the efficacy in clinical use has to be evaluated. PMID- 29593913 TI - The Impact of Pinless Navigation in Conventionally Aligned Total Knee Arthroplasty. AB - Background: Restoration of the mechanical axis is a main objective in total knee replacement (TKR). Aim of this study was to analyse the verification tool of a pinless navigation system in conventional TKR (cTKR). Methods: In a prospective study, 147 TKR were performed by conventional technique. Using the "pinless verification" mode of a smartphone based navigation system, the cutting block position and final resection plane for distal femur and proximal tibial resection were measured. If necessary, the block position or resection level were optimized, corrections were protocolled. Postoperatively, standardized radiographs were performed. Results: In 65.3%, intraoperative measurements changed the surgical procedure (corrections: 20.4% femoral, 25.9% tibial, 19% both). The additional time for surgery compared to cTKR averaged 6 minutes (79 +/ 15 versus 73 +/- 17 minutes). Using navigation data, the final femoral and tibial axes were in 93% within a range of +/-2 degrees . A mean difference of 1.4 degrees and 1.6 degrees could be shown between the final measurement of the navigation system and the postoperative mLDFA and mMPTA. Conclusion: Intraoperative pinless navigation has impact on the surgical procedure in the majority of cTKR. It represents a less time-consuming tool to improve implant position while maintaining the routine of conventional technique. PMID- 29593914 TI - Rituximab Induced Pulmonary Edema Managed with Extracorporeal Life Support. AB - Though rare, rituximab has been reported to induce severe pulmonary edema. We describe the first report of ECLS utilization for this indication. A 31-year-old female with severe thrombotic thrombocytopenic purpura developed florid pulmonary edema after rituximab infusion. Despite advanced ventilatory settings, she developed severe respiratory acidosis and remained hypoxemic with a significant vasopressor requirement. Since her pulmonary insult was likely transient, ECLS was considered. Due to combined cardiorespiratory failure, she received support with peripheral venoarterial ECLS. During her ECLS course, she received daily plasmapheresis and high dose steroids. Her pulmonary function recovered and she was decannulated after 8 days. She was discharged after 23 days without residual sequelae. PMID- 29593915 TI - Surgery to Treat Symptomatic Mobile Cecum Syndrome Is Safe and Associated with Good Recovery Outcomes. AB - The mobile cecum syndrome includes a spectrum of conditions. The cecal volvulus represents the acute form, with typical feature of a bowel obstruction that needs immediate operative treatment. On the other hand, a chronic form of mobile cecum syndrome which is the most common form reported a history of intermittent crampy abdominal pain, distension, and constipation. In this study, five patients came to our attention during the last ten years, presenting different symptoms due to a mobile cecum. All patients were investigated by several diagnostic techniques according to the specific clinical setting. All patients were found to have the cecum and ascending colon unattached to the posterior peritoneum. Surgery was the treatment of choice. In our experience, the best diagnostic technique was computed tomography scan, especially if performed in the Trendelenburg position. We also propose virtual colonoscopy as a good option for diagnosis (in patients with chronic syndrome) and follow-up after surgery. In conclusion, laparoscopic approach guaranteed a good result, with no symptoms of recurrence, in both acute and elective treatments. The diagnosis of mobile cecum needs a high index of suspicion and a targeted radiological investigation. Surgery, especially laparoscopic cecopexy and appendectomy, is the recommended treatment. PMID- 29593916 TI - Primary Pancreatic Burkitt's Lymphoma: A Case Report and Review of the Literature. AB - Primary pancreatic lymphoma (PPL) is of very rare occurrence as an extra nodal site of Non-Hodgkin's lymphoma (NHL). It represents less than 1% of NHL. Out of which Burkitt lymphoma of pancreas is of a rare presentation. It usually occurs in children and presenting in adults is uncommon. The prevalence of pancreatic Burkitt lymphoma is not known as the incidence is significantly low. Clinical features of PPL are predominantly nonspecific and can become difficult with associated inflammation of pancreas. Differentiation of lymphoma to adenocarcinoma is important as chemotherapy is the main stay of treatment in lymphoma. We report a case of 68-year-old female who presented with nonspecific symptoms and was found to have obstructive jaundice secondary to pancreatic head neoplasm which was proved to be pancreatic Burkitt lymphoma which is a rare presentation. PMID- 29593917 TI - A Case of Unresolved and Worsening Retroperitoneal Abscess. AB - Retroperitoneal abscess is a rare condition which is difficult to diagnose and treat because of its insidious onset. Herein, we present a case of retroperitoneal abscess secondary to a perforation that occurred during an ERCP. A 54-year-old female patient was admitted to an outside hospital with gallstone pancreatitis and underwent ERCP with sphincterotomy followed by laparoscopic cholecystectomy. An abdominal CT scan was performed at the outside hospital 10 days later for worsening abdominal pain which showed multiple loculated pockets in the right upper and lower quadrant. Her condition improved after IV antibiotics and percutaneous drainage. Her symptoms recurred a month later and she presented to our hospital. Repeat abdominal CT scan at our hospital revealed recurrence of her abscesses. Multiple drains were placed and the abscess cavity was washed out without much improvement. EGD revealed a small mucosal defect in the distal portion of the duodenal bulb which was closed successfully using an over-the-scope clip. Repeat CT scan after 8 weeks from the endoscopic closure showed near complete resolution of the abscess. ERCP-associated perforation is a rare complication and can be challenging to diagnose and treat; prompt recognition is mandatory for favorable prognosis. Our patient was managed successfully via nonsurgical approach. PMID- 29593918 TI - A Case of Polymicrobial Bacteremia in a Patient Undergoing Chemotherapy. AB - We report an aggressive case of polymicrobial bacteremia in a patient with renal pelvis carcinoma. A 76-year-old man developed watery diarrhea after undergoing chemotherapy. He became unconscious and went into shock. Laboratory data showed severe neutropenia, renal failure, and lactic acidosis. Chest radiography showed multiple opacities. He died despite aggressive fluid resuscitation, catecholamine administration, antibiotic treatment, and mechanical ventilation. Blood culture isolates included Escherichia coli, Klebsiella pneumoniae, Streptococcus pneumoniae, Acinetobacter baumannii, and Moraxella catarrhalis. The foci of bacteremia were the respiratory tract and the bowel. The two infection foci and polymicrobial bacteremia are thought to be associated with the patient's poor prognosis. Although polymicrobial bacteremia is rare, awareness of this condition and of the rare causative pathogens, such as A. baumannii and M. catarrhalis, especially in patients with comorbidities and immunosuppression will help treat the patients with bacteremia. PMID- 29593919 TI - Double Native Valve Infective Endocarditis due to Capnocytophaga canimorsus: First Reported Case Caused by a Lion Bite. AB - Capnocytophaga canimorsus is a Gram-negative bacilli that is part of the normal oral flora of dogs and some cats; it is well known to cause septicemia and endocarditis after their bite. This is the first reported case of infective endocarditis affecting both native mitral and aortic valves after a lion bite in a patient with heavy ethanol consumption, who ultimately died after valve replacements. PMID- 29593920 TI - A Case Report of Peritoneal Tuberculosis: A Challenging Diagnosis. AB - Peritoneal tuberculosis is a disease which can mimick malignancy especially in women who present with ascites and elevated CA125 levels. It should always be considered in differential diagnosis, but the diagnosis is rarely easy for clinicians. A young female patient who presented with abdomen tenderness and diagnosed with peritoneal tuberculosis as a result of performed tests is discussed hereby in the case report. We expect that this case report adds to the existing literature on this subject. PMID- 29593921 TI - Unilateral Asterixis in Arm and Leg Caused by Internal Capsula Stroke. AB - We report an unusual clinical manifestation of ischemic stroke with acute right sided asterixis affecting the arm as well as the leg due to a lesion in the left posterior limb of the internal capsula. After treatment with intravenous thrombolysis the patient made a good recovery. Notably, in this case unilateral asterixis affected the arm as well as the leg, resulting in postural and gait instability. In addition, damage in the basal ganglia-thalamo-cortical network, as in our patient, has to be distinguished from other supratentorial causes of acute asterixis like thalamic or frontal lobe lesions linked to the cerebello brainstem-thalamo-frontal lobe circuits. PMID- 29593922 TI - Nivolumab-Induced Encephalitis in Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome. AB - The treatment of cancer is a rapidly evolving field. As more chemotherapeutic agents become available, reporting the side effects of these agents in clinical practice becomes increasingly important. Nivolumab is one of the chemotherapeutic agents commonly used for treatment of renal cell carcinoma, metastatic melanoma, and metastatic non-small cell lung cancer. While common side effects are known and well documented, encephalitis is documented as an extremely rare side effect. We present the case of an extremely rare side effect to a common chemotherapeutic agent. PMID- 29593923 TI - Delayed Adjacent Level Spondylodiscitis after Initial Surgery with Instrumented Spinal Fusion: A Report of Three Cases and Review of the Literature. AB - To date, 2 cases of adjacent level spondylodiscitis occurring a few months after initial spinal fusion were reported. However, the development of delayed adjacent level spondylodiscitis is very rare. The authors report 3 cases of spondylodiscitis that occurred at the proximal adjacent level of the fused spine more than 1 year after the initial surgery. Antibiotic treatment was initially chosen in all three cases. In two of the cases, progressive neurological deficit occurred at the level of the infection due to compression of neural elements and spinal instability. For these patients, additional spinal fusion was performed. In each of the three cases, the selected treatment resulted in successful bony fusion at the level of the spondylodiscitis. According to the National Nosocomial Infections Surveillance System, deep wound infection is defined as occurring within 1 year after surgery with instrumentation. The spondylodiscitis in the present cases occurred more than 1 year after the initial surgery, suggesting that these cases may be considered as adjacent segment disease rather than surgical site infection. PMID- 29593924 TI - Subacute Urinary Retention due to a Subpubic Cartilaginous Cyst Treated with Surgical Resection and Internal Fixation: A Case Report and Review of the Literature. AB - A subpubic cartilaginous cyst is a rare mass lesion derived from the pubic symphysis, which can cause acute or subacute urinary retention. We report a case of a subpubic cartilaginous cyst in a 62-year-old woman that caused lower abdominal pain and subacute urinary retention, requiring surgical resection. On physical examination, a hard, flexible, nontender mass, 4 cm in diameter, was palpable along the lower border of the pubic bone, extending to the perineum. Magnetic resonance imaging revealed a clearly distinct (3.8 cm * 3.8 cm * 7.2 cm) mass on the midpelvic side of the pelvis, centered on the pubic joint. We proceeded with en bloc resection of the mass, including a resection margin of 1 cm on either side. The bony defect was fixed with a locking plate. On pathological assessment, the mass was diagnosed as a subpubic cartilaginous cyst arising from the cartilage of the pubic symphysis. No tumor recurrence was identified over a 4-year follow-up. Based on our experience, we propose that en bloc resection of the mass, including a wider resection centered on the pubic symphysis, with internal fixation, is a possible treatment for a subpubic cartilaginous cystic mass lesion. PMID- 29593925 TI - Hybrid Assistive Limb Intervention in a Patient with Late Neurological Deterioration after Thoracic Myelopathy Surgery due to Ossification of the Ligamentum Flavum. AB - Purpose: We evaluated improvements in gait after using the Hybrid Assistive Limb (HAL(r)) exoskeleton robot in a patient with late-onset neurological deterioration of lower extremity function after undergoing thoracic spine surgery for a myelopathy due to ossification of the ligamentum flavum. Case Presentation: A 70-year-old man participated in ten 20 min sessions of HAL intervention, twice weekly for five weeks. The effects of each HAL session were evaluated based on changes in performance on the 10 m walk test (10 MWT), lower limb kinematics quantified from motion capture, and the activation ratio of the gastrocnemius, measured before and after the intervention. Muscle activity was recorded using surface electromyography and synchronized to measured kinematics. The HAL intervention improved gait speed and step length, with an increase in the hip flexion angle during the swing phase and a decrease in the activation ratio of the gastrocnemius. The modified Ashworth scale improved from 1+ to 1 and International Standards for Neurological and Functional Classification of Spinal Cord Injury motor scores from 34 to 49. Conclusion: Intervention using the HAL exoskeleton robot may be an effective method to improve functional ambulation in patients with chronic spinal disorders. PMID- 29593926 TI - Chronological Progression of an Enlarged Styloid Process: A Case Report of Eagle Syndrome. AB - Eagle syndrome is characterized by an elongated styloid process. However, the time frame over which the styloid process becomes elongated and extends is unknown. How the condition worsens over time is also unclear. To date, there has been no report describing the chronologic change that occurs in the styloid process in Eagle syndrome. We describe a 53-year-old patient with Eagle syndrome in whom the styloid process enlarged progressively over time and the elongated styloid process fused with the hyoid bone. The styloid process was resected via a transcervical approach, and the patient's subjective symptoms improved. This is the first report showing how the styloid process can enlarge over a few years in a patient with Eagle syndrome. Surgical resection via a transcervical approach is an appropriate treatment for a patient in whom the styloid process has become excessively enlarged and elongated. PMID- 29593927 TI - A Case of Rare Complication of Inguinal Parietoplasty according to Lichtenstein: Entero Cutaneous Fistula. AB - Lichtenstein intervention is currently the classic model of the regulated treatment of inguinal hernias by direct local approach. This "tension-free" technique satisfies both patients and practitioners. However, it does not often evade severe complications of parietal surgery. The authors report their treatment experience in rural Africa of a late enterocutaneous fistula which aggravated an inguinal hernia repair according to the Lichtenstein procedure. Physiopathology, diagnosis, and treatment of that disease are analyzed in the light of literature. PMID- 29593928 TI - Extra-Anatomic Jump Graft from the Right Colic Vein: A Novel Technique to Manage Portal Vein Thrombosis in Liver Transplantation. AB - Background: In the context of cirrhosis, portal vein thrombosis (PVT) is present in 2.1% to 26% of patients. PVT is no longer considered an absolute contraindication for liver transplantation, and nowadays, surgical strategies depend on the extent of PVT. Complete PVT is associated with higher morbidity rates and poor prognosis, while comparable long-term outcomes can be achieved as long as physiological portal inflow is restored. Materials and Methods: We report our experience with a 45-year-old patient undergoing liver transplant with a PVT (stage III-b). To restore portal vein inflow to the liver, an extra-anatomic jump graft from the right colic vein with donor iliac vein interposition was constructed. Results: The patient recovered well, with a progressive improvement of the general conditions, and was finally discharged on p.o.d. 14. No anastomotic defects were found at the postoperative CT scan 10 months after the surgery. Conclusion: Our technical innovation represents a valid and safe alternative to the cavoportal hemitransposition, providing a proper flow restoration and reproducing a physiological setting, while avoiding the complications related to the cavoportal shunt. We believe that the reconstitution of liver portal inflow should be obtained with the most physiological approach possible and considering long-term liver function. PMID- 29593929 TI - Colorectal Cancer Presenting as Single Pulmonary Hilar Lymph Node Metastasis. AB - Colorectal carcinoma is the second biggest cancer responsible for mortality. Lung metastasis is the commonest, following the liver. It is not uncommon to perform pulmonary metastasectomy and identify mediastinal metastasis. Previous studies have identified incidental lymph node involvement following routine mediastinal lymph node clearance in 20-50% of cases. However, solitary intrathoracic lymph node metastasis is exceedingly rare. Even when present, it is usually metachronous. In our case, we present an exceedingly rare case whereby the intrathoracic lymph node metastasis is solitary, not accompanying pulmonary disease and with no liver metastasis. We also review the evidence for mediastinal lymphadenectomy in the literature. PMID- 29593930 TI - Mucinous Carcinomatosis: A Rare Association between an Ovarian Tumor and an E GIST. AB - Pseudomyxoma peritonei (PMP) and extragastrointestinal stromal tumors (E-GISTs) are both rare entities. Most of the time, PMP is associated with an appendiceal tumor. An ovarian mucinous tumor can mimic appendiceal metastases. E-GIST is a mesenchymal tumor that can arise from the omentum, retroperitoneum, mesentery, or pleura. We present a case of an 87-year-old woman with mucinous carcinomatosis and acute intestinal occlusion submitted to an emergency laparotomy. She has found to have a borderline mucinous tumor of the ovary from the intestinal type with several lesions of pseudomyxoma peritonei and an E-GIST from the epiploons retrocavity (intermediated risk). In the literature, no relation was found between these two rare tumors. E-GIST was an incidental finding in the context of a mucinous carcinomatosis. PMID- 29593931 TI - A Case of Fibrous Pseudotumor in the Scrotum: Challenge for Diagnosis and Testicular Preservation. AB - A paratesticular fibrous pseudotumor is a relatively rare benign disease. Preoperatively diagnosing a fibrous pseudotumor is challenging because distinguishing these masses from malignant tumors on the basis of clinical and radiological findings can be difficult. We present a case of a 28-year-old man who presented with a painless palpable mass in the right scrotum; the fibrous pseudotumor of the tunica vaginalis was treated with organ-sparing surgery. Computed tomography and magnetic resonance imaging revealed paratesticular tumors. Testicular tumor marker levels were within normal limits. We scheduled the patient to undergo tumor biopsy combined with intraoperative rapid diagnosis. Frozen section assessment suggested a fibrous pseudotumor without malignancy. We successfully performed organ-sparing surgery. Testicular-sparing surgery combined with frozen section assessment is primarily used for treating paratesticular fibrous pseudotumors. PMID- 29593932 TI - Masculinity and Bystander Attitudes: Moderating Effects of Masculine Gender Role Stress. AB - Objective: The purpose of the current study was to examine the bystander decision making process as a mechanism by which men's adherence to various dimensions of traditional masculinity is associated with their confidence to intervene in sexually aggressive events. Further, this study examined the stress men experience from their attempts to adhere to traditional male gender roles as a moderator of this mediational path. Method: Participants (n = 252) completed measures of traditional masculinity, decisional balance (i.e., weighing the pros and cons) for intervening, masculine gender roles stress, and bystander efficacy. Results: The belief that men must attain social status was associated with more confidence in men's ability to intervene. This effect was mediated by greater perceived positive consequences for intervention among men high, but not low, in masculine gender role stress. The belief that men should be tough and aggressive was associated with greater perceived negative consequences for intervention and less confidence to intervene. The belief that men should not act in stereotypically feminine ways was directly associated with less confidence for intervention. Conclusions: Findings highlight the importance of examining masculinity from a multidimensional perspective to better understand how adherence to various norms differentially influences bystander behavior. These findings may help to inform bystander intervention programming. PMID- 29593933 TI - Comparing men who have sex with men and transgender women who use Grindr, other similar social and sexual networking apps, or no social and sexual networking apps: Implications for recruitment and health promotion. AB - Objective: Researchers and public health professionals have increased their attention to GPS-based social and sexual networking applications (apps) tailored to gay, bisexual, other men who have sex with men (MSM) and transgender women. These populations continue to be disproportionately affected by HIV in the United States, therefore these apps, in particular Grindr, have become an important sampling venue for the recruitment of HIV-related research participants. As such, it is essential to identify differences among app users to avoid potential sampling bias. This paper seeks to identify differences in MSM and transgender women who use Grindr and those who use other similar apps. Methods: A community based participatory research (CBPR) approach was used to recruit participants online who then completed a 25-item anonymous survey. Five domains were assessed: sociodemographics, HIV testing, sexual risk, substance abuse, and use of GPS based social and sexual networking apps. Results: 457 participants completed surveys. There were significant differences in the sociodemographic characteristics by app use, including age, race/ethnicity, sexual orientation, and outness. After adjusting for the sociodemographic characteristics associated with app use, there were significant differences in HIV risk and substance use between the groups. Conclusion: This paper is the first to report on findings that compare MSM and transgender women who report using Grindr to MSM and transgender women who report using other similar apps. GPS-based social and sexual networking apps may offer a valuable recruitment tool for future HIV research seeking to recruit populations at increased risk for HIV or those living with HIV for therapeutic trials. Because of the differences identified across users of different apps, these findings suggest that if researchers recruited participants from just one app, they could end up with a sample quite different than if they had recruited MSM and transgender women from other apps. PMID- 29593934 TI - Semiparametric Mixed Models for Medical Monitoring Data: An Overview. AB - The potential to characterize nonlinear progression over time is now possible in many health conditions due to advancements in medical monitoring and more frequent data collection. It is often of interest to investigate differences between experimental groups in a study or identify the onset of rapid changes in the response of interest using medical monitoring data; however, analytic challenges emerge. We review semiparametric mixed-modeling extensions that accommodate medical monitoring data. Throughout the review, we illustrate these extensions to the semiparametric mixed-model framework with an application to prospective clinical data obtained from 24-hour ambulatory blood pressure monitoring, where it is of interest to compare blood pressure patterns from children with obstructive sleep apnea to those arising from healthy controls. PMID- 29593935 TI - Diagnosis and Clinical Management of Human Papilloma Virus-Related Gingival Squamous Cell Carcinoma in a Patient With Leukemia: A Case Report. AB - Introduction: Close clinical inspection for intraoral lesions in patients with leukemia that develop chronic graft-versus-host disease (cGVHD) is critical. Additionally, neoplasias developing in bone marrow transplant patients after treatment for leukemia represent a significant obstacle for long-term patient survival, necessitating lifetime follow-up by health care providers. This case report describes the identification, diagnosis, and treatment of gingival squamous cell carcinoma (SCC) in a patient with leukemia who was treated previously with a stem cell transplant and referred for routine periodontal care. Case Presentation: A 53-year-old male was referred to the Department of Periodontics for an assessment of tooth #10 with 2+ mobility and associated cross bite occlusion. The patient was diagnosed with acute myeloid leukemia at age 39 years, received hematopoietic stem cell transplantation (HSCT), and later developed cGVHD followed by human papilloma virus (HPV) infections. During the periodontal evaluation, a large, non-painful, exophytic, alveolar gingival mass was identified and later diagnosed as SCC. It is unusual that oral SCC presents as an exophytic, gingival swelling. The patient received comprehensive periodontal management in coordination with his otolaryngology team before and during the diagnosis of SCC secondary to cGVHD and HPV infection. Conclusions: Patients with a history of HSCT treatment for leukemia and subsequent cGVHD are at a high risk of developing second primary oral malignancies, including SCC. Exposure to oncogenic HPV infection may compound this risk. Therefore, it is important for dentists to be aware of special treatment concerns and to frequently screen these patients to achieve early diagnosis and treatment of these neoplasms. PMID- 29593936 TI - Oral Effects and Early Implant Survival Results After Imatinib Discontinuation Therapy for Chronic Myelogenous Leukemia: A Case Report. AB - Introduction: Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. Case Presentation: A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long-term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation. Conclusions: Patients with a history of long-term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long-term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals. PMID- 29593937 TI - 2017 Reviewer Acknowledgment. PMID- 29593938 TI - Oropharynx HPV status and its relation to HIV infection. AB - Background: The number of oropharyngeal lesions caused by HPV (Human papillomavirus) has been increasing worldwide in the past years. In spite of the clinical relevance of HPV infection in the anogenital tract of HIV-positive patients, the relevance of oropharynx HPV infection in these patients is not clear. The aim of the present study was to detect HPV infection, and clinical and cytological changes in the oropharynx of HIV-positive patients. Methods: Samples collected from the oropharynx of 100 HIV-positive patients were subjected to hybrid capture (HC), conventional and liquid-based cytology. Clinical data were also collected to investigate the relation with HPV status. Results: High and low risk types of HPV were present in 8% and 16.7% of the total sample. The mean +/- sd (maximum-minimum) of the relative ratio light unit (RLU)/cutoff (CO) was 2.94 +/- 2.58 (1.09-7.87) and 1.61 +/- 0.65 (1.07-2.8) for high- and low-risk-HPV, respectively. By cytology, dysplasia was not detected, but atypical squamous cells of undetermined significance (ASC-US) were diagnosed in two samples. No clinical change, suggestive of dysplasia/cancer, was detected. Conclusion: Our study was able to detect and characterize HPV infection by hybrid capture, which may represent a good tool for screening and follow-up of HPV in the studied population. The frequency and viral load of HPV were low. Neither clinical nor cytological changes suggestive of dysplasia/neoplasia were observed in oropharynx of HIV-positive patients. PMID- 29593939 TI - Quantitative trait loci associated with soft wheat quality in a cross of good by moderate quality parents. AB - Information on the genetic control of the quality traits of soft wheat (Triticum aestivum) is essential for breeding. Our objective was to identify QTL associated with end-use quality. We developed 150 F4-derived lines from a cross of Pioneer 26R46 * SS550 and tested them in four environments. We measured flour yield (FY), softness equivalent (SE), test weight (TW), flour protein content (FP), alkaline water retention capacity (AWRC), and solvent retention capacity (SRC) of water (WA), lactic acid (LA), sucrose (SU), sodium carbonate (SO). Parents differed for nine traits, transgressive segregants were noted, and heritability was high (0.67 to 0.90) for all traits. We detected QTL distributed on eight genomic regions. The QTL with the greatest effects were located on chromosome 1A, 1B, and 6B with each affecting at least five of ten quality traits. Pioneer 26R46 is one of the best quality soft wheats. The large-effect QTL on 1A novel and accounted for much of the variation for AWRC (r2 = 0.26), SO (0.26) and SE (0.25), and FY (0.15) and may explain why Pioneer 26R46 has such superior quality. All alleles that increased a trait came from the parent with the highest trait value. This suggests that in any population that marker-assisted selection for these quality traits could be conducted by simply selecting for the alleles at key loci from the parent with the best phenotype without prior mapping.

AB - Tufted Puffin (Fratercula cirrhata) populations have experienced dramatic declines since the mid-19th century along the southern portion of the species range, leading citizen groups to petition the United States Fish and Wildlife Service (USFWS) to list the species as endangered in the contiguous US. While there remains no consensus on the mechanisms driving these trends, population decreases in the California Current Large Marine Ecosystem suggest climate related factors, and in particular the indirect influence of sea-surface temperature on puffin prey. Here, we use three species distribution models (SDMs) to evaluate projected shifts in habitat suitable for Tufted Puffin nesting for the year 2050 under two future Intergovernmental Panel on Climate Change (IPCC) emission scenarios. Ensemble model results indicate warming marine and terrestrial temperatures play a key role in the loss of suitable Tufted Puffin nesting conditions in the California Current under both business-as-usual (RCP 8.5) and moderated (RCP 4.5) carbon emission scenarios, and in particular, that mean summer sea-surface temperatures greater than 15 degrees C are likely to make habitat unsuitable for breeding. Under both emission scenarios, ensemble model results suggest that more than 92% of currently suitable nesting habitat in the California Current is likely to become unsuitable. Moreover, the models suggest a net loss of greater than 21% of suitable nesting sites throughout the entire North American range of the Tufted Puffin, regardless of emission reduction strategies. These model results highlight continued Tufted Puffin declines-particularly among southern breeding colonies-and indicate a significant risk of near-term extirpation in the California Current Large Marine Ecosystem. PMID- 29593942 TI - The risk of hospitalization for respiratory tract infection (RTI) in children who are treated with high-dose IVIG in Kawasaki Disease: a nationwide population based matched cohort study. AB - Background: Kawasaki disease (KD) is an immune-mediated systemic vasculitis, and infection plays an important role in the pathophysiology of KD. The susceptibility to infectious disease in patients with KD remains largely unclear. This study aimed to investigate the risk of respiratory tract infection (RTI) related hospitalizations in children with KD. Methods: Data from the Taiwanese National Health Insurance Research Database was analyzed. We excluded patients with history of congenital abnormality, allergic diseases, or hospitalization history. Children with KD were selected as KD group and age- and sex-matched non KD patients were selected as control group with 1:4 ratio. Both cohorts were tracked for one year to investigate the incidences of RTI-related hospitalizations. Cox regression hazard model was used to adjust for confounding factors and calculate the adjusted hazard ratio (aHR). Results: Between January 1996 and December 2012, 4,973 patients with KD were identified as the KD group and 19,683 patients were enrolled as the control group. An obviously reduced risk of RTI-related hospitalizations was observed in KD patients (aHR: 0.75, 95% CI [0.66-0.85]). The decreased risk persisted through the first six-months follow-up period with a peak protection in 3-6 months (aHR: 0.49, 95% CI [0.37-0.64]). Conclusions: KD patients had approximately half reduction of risk for RTI-related hospitalizations. The protective effects persisted for at least six months. Further studies are warranted to elucidate the entire mechanism and investigate the influences of intravenous immunoglobulin. PMID- 29593941 TI - Dynamics of Zika virus outbreaks: an overview of mathematical modeling approaches. AB - Background: The Zika virus was first discovered in 1947. It was neglected until a major outbreak occurred on Yap Island, Micronesia, in 2007. Teratogenic effects resulting in microcephaly in newborn infants is the greatest public health threat. In 2016, the Zika virus epidemic was declared as a Public Health Emergency of International Concern (PHEIC). Consequently, mathematical models were constructed to explicitly elucidate related transmission dynamics. Survey Methodology: In this review article, two steps of journal article searching were performed. First, we attempted to identify mathematical models previously applied to the study of vector-borne diseases using the search terms "dynamics," "mathematical model," "modeling," and "vector-borne" together with the names of vector-borne diseases including chikungunya, dengue, malaria, West Nile, and Zika. Then the identified types of model were further investigated. Second, we narrowed down our survey to focus on only Zika virus research. The terms we searched for were "compartmental," "spatial," "metapopulation," "network," "individual-based," "agent-based" AND "Zika." All relevant studies were included regardless of the year of publication. We have collected research articles that were published before August 2017 based on our search criteria. In this publication survey, we explored the Google Scholar and PubMed databases. Results: We found five basic model architectures previously applied to vector-borne virus studies, particularly in Zika virus simulations. These include compartmental, spatial, metapopulation, network, and individual-based models. We found that Zika models carried out for early epidemics were mostly fit into compartmental structures and were less complicated compared to the more recent ones. Simple models are still commonly used for the timely assessment of epidemics. Nevertheless, due to the availability of large-scale real-world data and computational power, recently there has been growing interest in more complex modeling frameworks. Discussion: Mathematical models are employed to explore and predict how an infectious disease spreads in the real world, evaluate the disease importation risk, and assess the effectiveness of intervention strategies. As the trends in modeling of infectious diseases have been shifting towards data-driven approaches, simple and complex models should be exploited differently. Simple models can be produced in a timely fashion to provide an estimation of the possible impacts. In contrast, complex models integrating real-world data require more time to develop but are far more realistic. The preparation of complicated modeling frameworks prior to the outbreaks is recommended, including the case of future Zika epidemic preparation.

AB - Even with the great advances in immunotherapy in recent years, the response rate to immune checkpoint inhibitor therapy for non-small cell lung cancer is only about 20%. We aimed to identify new features that would better predict which patients can benefit from an immune checkpoint blocker. This study is based on the publicly available gene expression data from The Cancer Genome Atlas lung cancer samples and the newly released mutation annotation data. We performed a comprehensive analysis by correlating patient cytolytic activity index, mutational signatures, and other immune characteristics in four stratified patient groups. The results cytolytic activity index are highly correlated with immune infiltration scores, T cell infiltration scores and TCR clonality scores in lung cancer. In addition, we observed that the mutational event signatures might play a more important role in predicting immunotherapy response in squamous cell carcinoma and two subgroups of adenocarcinomas. Our analysis illustrates the utility of integrating both tumor immune and genomic landscape for a better understanding of immune response in lung cancer. PMID- 29593944 TI - The first Oligocene sea turtle (Pan-Cheloniidae) record of South America. AB - The evolution and occurrence of fossil sea turtles at the Pacific margin of South America is poorly known and restricted to Neogene (Miocene/Pliocene) findings from the Pisco Formation, Peru. Here we report and describe the first record of Oligocene (late Oligocene, ~24 Ma) Pan-Cheloniidae sea turtle remains of South America. The fossil material corresponds to a single, isolated and well-preserved costal bone found at the Montanita/Olon locality, Santa Elena Province, Ecuador. Comparisons with other Oligocene and extant representatives allow us to confirm that belongs to a sea turtle characterized by: lack of lateral ossification, allowing the dorsal exposure of the distal end of ribs; dorsal surface of bone sculptured, changing from dense vermiculation at the vertebral scute region to anastomosing pattern of grooves at the most lateral portion of the costal. This fossil finding shows the high potential that the Ecuadorian Oligocene outcrops have in order to explore the evolution and paleobiogeography distribution of sea turtles by the time that the Pacific and the Atlantic oceans were connected via the Panama basin. PMID- 29593945 TI - Postoperative Seizure Rate After Transcortical Resection of Subcortical Brain Tumors and Colloid Cysts: A Single Surgeon's Experience. AB - When deciding on a surgical route to reach subcortical brain tumors and colloid cysts, many surgeons advocate the use of transcallosal, transsulcal, or skull base approaches over transcortical approaches due to a high reported incidence of postoperative seizures. We have retrospectively analyzed all patients operated upon by a senior neurosurgeon (Ricardo J. Komotar) who undertook transcortical approaches for the resection of subcortical brain tumors and colloid cysts. We have also performed a comprehensive review of the literature to estimate postoperative seizure risk after transcortical approaches for the resection of deep tumors and colloid cysts. Of 27 patients who underwent transcortical approaches for the resection of subcortical brain tumors and colloid cysts, zero had postoperative seizures. A comprehensive review of the literature shows an 8.3% postoperative risk of seizures after the transcortical approach. Our institution has never experienced a postoperative seizure following the transcortical approach for the resection of deep tumors and colloid cysts. For this reason, we advocate selecting a surgical approach that obtains adequate lesion exposure and minimizes the violation and retraction of eloquent cortex, venous structures, and white matter tracts, rather than on presumed postoperative seizure risk. PMID- 29593946 TI - Prevalence of Type 2 Diabetes Mellitus Among Urban Bihari Communities in Dhaka, Bangladesh: A Cross-sectional Study in a Minor Ethnic Group. AB - Introduction The prevalence, disease progression, and treatment outcomes for patients with type 2 diabetes vary significantly between ethnic groups. The Bihari community constitutes one of the most vulnerable populations in Bangladesh on the basis of access to health services and other fundamental rights. Our study aimed at finding out the prevalence and risk factors of type 2 diabetes among the Bihari adults in Dhaka city. Methods This cross-sectional community-based study was carried out among stranded Pakistanis (known as Bihari) living in camps in the Mirpur area from July 2014 to June 2015. Laboratory-based oral glucose tolerance test (OGTT) was the basis for the diagnosis of type 2 diabetes mellitus (DM). Anthropometric measurements, blood pressure, biochemical tests, family history, and socioeconomic information were obtained to determine the risk factors. Results The prevalence of diabetes mellitus (DM), impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) were estimated at 10.11%, 8.74%, and 4.55%, respectively. Increased diastolic blood pressure, serum triglyceride, and cholesterol level were observed to be significantly (p < 0.05) associated with diabetes. Also, the presence of diabetes, high blood pressure, and obesity among relatives significantly increased the probability of diabetes. Conclusions To the best of our knowledge, this is the first study on diabetes prevalence among the Bihari community in Bangladesh. The prevalence of type 2 diabetes mellitus was found to be higher among the Bihari community compared to the general population in Bangladesh. Health planners and policymakers should realize the alarming situation and identified risk factors and consider the minor ethnic groups during decision-making regarding prevention and control of diabetes and other noncommunicable diseases. PMID- 29593947 TI - Angioplasty is an Effective Treatment for Vasospasm Following Pituitary Apoplexy and Tumor Resection. AB - Pituitary apoplexy is a clinical syndrome characterized by acute headache, visual changes, and decreased consciousness occurring in association with hemorrhage or infarct of an existing pituitary adenoma. Surgical management involves tumor resection and decompression of surrounding structures including the optic apparatus. Vasospasm is a rare but potentially devastating complication of pituitary apoplexy. We present a case of pituitary apoplexy in a 28-year-old male treated with emergent endoscopic transsphenoidal resection. On postoperative day seven, following surgical resection, the patient developed neurologic deficits and motor weakness, and severe vasospasm was diagnosed. This is a novel case of intra-arterial verapamil and angioplasty used to treat vasospasm following surgical decompression for pituitary apoplexy. The patient experienced complete recovery of motor deficits following treatment. The authors propose angioplasty as an effective treatment for postoperative vasospasm following transphenoidal surgery for pituitary apoplexy in the presence of focal vessel stenosis. PMID- 29593948 TI - Isolating the roles of different forcing agents in global stratospheric temperature changes using model integrations with incrementally added single forcings. AB - Satellite instruments show a cooling of global stratospheric temperatures over the whole data record (1979-2014). This cooling is not linear, and includes two descending steps in the early 1980s and mid-1990s. The 1979-1995 period is characterized by increasing concentrations of ozone depleting substances (ODS) and by the two major volcanic eruptions of El Chichon (1982) and Mount Pinatubo (1991). The 1995-present period is characterized by decreasing ODS concentrations and by the absence of major volcanic eruptions. Greenhouse gas (GHG) concentrations increase over the whole time period. In order to isolate the roles of different forcing agents in the global stratospheric temperature changes, we performed a set of AMIP-style simulations using the NASA Goddard Earth Observing System Chemistry-Climate Model (GEOSCCM). We find that in our model simulations the cooling of the stratosphere from 1979 to present is mostly driven by changes in GHG concentrations in the middle and upper stratosphere and by GHG and ODS changes in the lower stratosphere. While the cooling trend caused by increasing GHGs is roughly constant over the satellite era, changing ODS concentrations cause a significant stratospheric cooling only up to the mid-1990s, when they start to decrease because of the implementation of the Montreal Protocol. Sporadic volcanic events and the solar cycle have a distinct signature in the time series of stratospheric temperature anomalies but do not play a statistically significant role in the long-term trends from 1979 to 2014. Several factors combine to produce the step-like behavior in the stratospheric temperatures: in the lower stratosphere, the flattening starting in the mid 1990's is due to the decrease in ozone depleting substances; Mount Pinatubo and the solar cycle cause the abrupt steps through the aerosol-associated warming and the volcanically induced ozone depletion. In the middle and upper stratosphere, changes in solar irradiance are largely responsible for the step-like behavior of global temperatures anomalies, together with volcanically induced ozone depletion and water vapor increases in the post-Pinatubo years. PMID- 29593949 TI - A Vesicular Stomatitis Virus-Inspired DNA Nanocomplex for Ovarian Cancer Therapy. AB - Gene therapy provides a novel method for cancer therapy. This study shows a DNA nanocomplex that is inspired from vesicular stomatitis virus (VSV) for ovarian cancer therapy. This DNA nanocomplex consists of a cationized monomethoxy poly (ethylene glycol)-poly (d,l-lactide) (MPEG-PLA) nanoparticle and a plasmid encoding the matrix protein of vesicular stomatitis virus (VSVMP) that plays a critical role in the VSV-induced apoptosis of cancer cells. The cationized MPEG PLA nanoparticle that is self-assembled by MPEG-PLA copolymer and N -[1-(2,3 dioleoyloxy) propyl]-N,N,N-trimethylammonium chloride (DOTAP) has low cytotoxicity and high transfection efficiency (>80%). Intraperitoneal administration of the p VSVMP nanocomplex remarkably inhibits the intraperitoneal metastasis of ovarian cancer and does not cause significant systemic toxicity. The apoptosis induction and anti-angiogenesis are involved in the anticancer mechanism. This work demonstrates a VSV-inspired DNA nanocomplex that has potential application for the treatment of intraperitoneal metastasis of ovarian cancer. PMID- 29593950 TI - Characterization of HIF-1alpha/Glycolysis Hyperactive Cell Population via Small Molecule-Based Imaging of Mitochondrial Transporter Activity. AB - The characterization of cancer stem-like cells (CSCs) has profound implications for elucidating cancer biology and developing treatment strategies. Although surface markers are already used to identify CSCs, the expression of these markers is controversially linked to the phenotypes in different types of tumors and does not represent all functionally relevant of CSCs. Very recently, hyperactive HIF-1alpha/glycolysis metabolic pathway is recognized as a master regulator of CSCs. In this study, a near-infrared fluorescent small-molecule, IR 780, is identified for the exclusive characterization of human CSCs through the HIF-1alpha/glycolysis dependent mitochondrial transporter ABCB10's activity. The results identified for the first time that ABCB10 is involved in the preferential uptake of IR-780 in CSCs, which is regulated by HIF-1alpha via the direct interaction with the binding site of ABCB10 gene promoter region. In addition, IR 780 is demonstrated to conjugate with anticancer drug 5-fluorouracil to act as a potential drug delivery carrier for CSC-targeted therapy. Thus, the studies provide a new rational approach independent of surface markers to characterize CSCs via small-molecule-based imaging of HIF-1alpha/glycolysis hyperactive metabolic pathway dependent mitochondrial transporter's activity, which holds promise for the further development of CSCs targeted diagnostic and therapeutic strategies. PMID- 29593951 TI - Enhanced Photodynamic Cancer Treatment by Mitochondria-Targeting and Brominated Near-Infrared Fluorophores. AB - A noninvasive and selective therapy, photodynamic therapy (PDT) is widely researched in clinical fields; however, the lower efficiency of PDT can induce unexpected side effects. Mitochondria are extensively researched as target sites to maximize PDT effects because they play crucial roles in metabolism and can be used as cancer markers due to their high transmembrane potential. Here, a mitochondria targeting photodynamic therapeutic agent (MitDt) is developed. This photosensitizer is synthesized from heptamethine cyanine dyes, which are conjugated or modified as follows. The heptamethine meso-position is conjugated with a triphenylphosphonium derivative for mitochondrial targeting, the N-alkyl side chain is modified for regulation of charge balance and solubility, and the indolenine groups are brominated to enhance reactive oxygen species generation (ROS) after laser irradiation. The synthesized MitDt increases the cancer uptake efficiency due to the lipo-cationic properties of the triphenylphosphonium, and the PDT effects of MitDt are amplified after laser irradiation because mitochondria are susceptible to ROS, the response to which triggers an apoptotic anticancer effect. Consequently, these hypotheses are demonstrated by in vitro and in vivo studies, and the results indicate strong potential for use of MitDts as efficient single-molecule-based PDT agents for cancer treatment. PMID- 29593952 TI - Toroidal Localized Spoof Plasmons on Compact Metadisks. AB - Localized spoof surface plasmons (LSSPs) have recently emerged as a new research frontier due to their unique properties and increasing applications. Despite the importance, most of the current researches only focus on electric/magnetic LSSPs. Very recent research has revealed that toroidal LSSPs, LSSPs modes with multipole toroidal moments, can be achieved at a point defect in a 2D groove metal array. However, this metamaterial shows the limitations of large volume and poor compatibility to photonic integrated circuits. To overcome the above challenges, here it is proposed and experimentally demonstrated compact planar metadisks based on split ring resonators to support the toroidal LSSPs at microwave frequencies. Additionally, it is experimentally demonstrated that the toroidal LSSPs resonance is very sensitive to the structure changes and the background medium. These might facilitate its utilization in the design and application of plasmonic deformation sensors and the refractive index sensors. PMID- 29593953 TI - Multifunctional Sandwich-Structured Electrolyte for High-Performance Lithium Sulfur Batteries. AB - Due to its high theoretical energy density (2600 Wh kg-1), low cost, and environmental benignity, the lithium-sulfur (Li-S) battery is attracting strong interest among the various electrochemical energy storage systems. However, its practical application is seriously hampered by the so-called shuttle effect of the highly soluble polysulfides. Herein, a novel design of multifunctional sandwich-structured polymer electrolyte (polymer/cellulose nonwoven/nanocarbon) for high-performance Li-S batteries is demonstrated. It is verified that Li-S battery with this sandwich-structured polymer electrolyte delivers excellent cycling stability (only 0.039% capacity decay cycle-1 on average exceeding 1500 cycles at 0.5 C) and rate capability (with a reversible capacity of 594 mA h g-1 at 4 C). These electrochemical performances are attributed to the synergistic effect of each layer in this unique sandwich-structured polymer electrolyte including steady lithium stripping/plating, strong polysulfide absorption ability, and increased redox reaction sites. More importantly, even with high sulfur loading of 4.9 mg cm-2, Li-S battery with this sandwich-structured polymer electrolyte can deliver high initial areal capacity of 5.1 mA h cm-2. This demonstrated strategy here may open up a new era of designing hierarchical structured polymer electrolytes for high-performance Li-S batteries. PMID- 29593954 TI - Recent Progress on MOF-Derived Heteroatom-Doped Carbon-Based Electrocatalysts for Oxygen Reduction Reaction. AB - The oxygen reduction reaction (ORR) is the core reaction of numerous sustainable energy-conversion technologies such as fuel cells and metal-air batteries. It is crucial to develop a cost-effective, highly active, and durable electrocatalysts for ORR to overcome the sluggish kinetics of four electrons pathway. In recent years, the carbon-based electrocatalysts derived from metal-organic frameworks (MOFs) have attracted tremendous attention and have been shown to exhibit superior catalytic activity and excellent intrinsic properties such as large surface area, large pore volume, uniform pore distribution, and tunable chemical structure. Here in this review, the development of MOF-derived heteroatom-doped carbon-based electrocatalysts, including non-metal (such as N, S, B, and P) and metal (such as Fe and Co) doped carbon materials, is summarized. It furthermore, it is demonstrated that the enhancement of ORR performance is associated with favorably well-designed porous structure, large surface area, and high-tensity active sites. Finally, the future perspectives of carbon-based electrocatalysts for ORR are provided with an emphasis on the development of a clear mechanism of MOF-derived non-metal-doped electrocatalysts and certain metal-doped electrocatalysts. PMID- 29593955 TI - Polymer Functionalization of Isolated Mitochondria for Cellular Transplantation and Metabolic Phenotype Alteration. AB - Aberrant mitochondrial energy transfer underlies prevalent chronic health conditions, including cancer, cardiovascular, and neurodegenerative diseases. Mitochondrial transplantation represents an innovative strategy aimed at restoring favorable metabolic phenotypes in cells with dysfunctional energy metabolism. While promising, significant barriers to in vivo translation of this approach abound, including limited cellular uptake and recognition of mitochondria as foreign. The objective is to functionalize isolated mitochondria with a biocompatible polymer to enhance cellular transplantation and eventual in vivo applications. Herein, it is demonstrated that grafting of a polymer conjugate composed of dextran with triphenylphosphonium onto isolated mitochondria protects the organelles and facilitates cellular internalization compared with uncoated mitochondria. Importantly, mitochondrial transplantation into cancer and cardiovascular cells has profound effects on respiration, mediating a shift toward improved oxidative phosphorylation, and reduced glycolysis. These findings represent the first demonstration of polymer functionalization of isolated mitochondria, highlighting a viable strategy for enabling clinical applications of mitochondrial transplantation. PMID- 29593956 TI - Dopant-Free and Carrier-Selective Heterocontacts for Silicon Solar Cells: Recent Advances and Perspectives. AB - By combining the most successful heterojunctions (HJ) with interdigitated back contacts, crystalline silicon (c-Si) solar cells (SCs) have recently demonstrated a record efficiency of 26.6%. However, such SCs still introduce optical/electrical losses and technological issues due to parasitic absorption/Auger recombination inherent to the doped films and the complex process of integrating discrete p+- and n+-HJ contacts. These issues have motivated the search for alternative new functional materials and simplified deposition technologies, whereby carrier-selective contacts (CSCs) can be formed directly with c-Si substrates, and thereafter form IBC cells, via a dopant-free method. Screening and modifying CSC materials in a wider context is beneficial for building dopant-free HJ contacts with better performance, shedding new light on the relatively mature Si photovoltaic field. In this review, a significant number of achievements in two representative dopant-free hole-selective CSCs, i.e., poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate)/Si and transition metal oxides/Si, have been systemically presented and surveyed. The focus herein is on the latest advances in hole-selective materials modification, interfacial passivation, contact resistivity, light-trapping structure and device architecture design, etc. By analyzing the structure-property relationships of hole-selective materials and assessing their electrical transport properties, promising functional materials as well as important design concepts for such CSCs toward high-performance SCs have been highlighted. PMID- 29593957 TI - Multiplex Photoluminescent Silicon Nanoprobe for Diagnostic Bioimaging and Intracellular Analysis. AB - Herein, a label-free multiplex photoluminescent silicon nanoprobe (PLSN-probe) is introduced as a potential substitute for quantum dots (QDs) in bioimaging. An inherently non-photoluminescent silicon substrate is altered to create the PLSN probe, to overcome the major drawbacks of presently available QDs. Additionally, crystallinity alterations of the multiplane crystalline PLSN-probes lead to broad absorption and multiplex fluorescence emissions, which are attributed to the simultaneous existence of multiple crystal planes. The PLSN-probe not only demonstrates unique optical properties that can be exploited for bioimaging but also exhibits cell-selective uptake that allows the differentiation and diagnosis of HeLa and fibroblast cells. Moreover, multiplex emissions of the PLSN-probe illuminate different organelles such as the nucleus, nucleolemma, and cytoskeleton, depending on size-based preferential uptake by the cell organs. This in vitro study reveals that cancerous HeLa cells have a higher propensity for taking up the PLSN-probe compared to fibroblast cells, allowing the diagnosis of cancerous HeLa cells. Additionally, the fluorescence intensity per unit area of the cell is found to be a reliable means for distinguishing between dead and healthy cells. It is anticipated that the multifunctionality of the PLSN-probes will lead to better insight into the use of such probes for bioimaging and diagnosis applications. PMID- 29593958 TI - 3D-Bioprinted Osteoblast-Laden Nanocomposite Hydrogel Constructs with Induced Microenvironments Promote Cell Viability, Differentiation, and Osteogenesis both In Vitro and In Vivo. AB - An osteoblast-laden nanocomposite hydrogel construct, based on polyethylene glycol diacrylate (PEGDA)/laponite XLG nanoclay ([Mg5.34Li0.66Si8O20(OH)4]Na0.66, clay)/hyaluronic acid sodium salt (HA) bio-inks, is developed by a two-channel 3D bioprinting method. The novel biodegradable bio-ink A, comprised of a poly(ethylene glycol) (PEG)-clay nanocomposite crosslinked hydrogel, is used to facilitate 3D-bioprinting and enables the efficient delivery of oxygen and nutrients to growing cells. HA with encapsulated primary rat osteoblasts (ROBs) is applied as bio-ink B with a view to improving cell viability, distribution uniformity, and deposition efficiency. The cell-laden PEG-clay constructs not only encapsulated osteoblasts with more than 95% viability in the short term but also exhibited excellent osteogenic ability in the long term, due to the release of bioactive ions (magnesium ions, Mg2+ and silicon ions, Si4+), which induces the suitable microenvironment to promote the differentiation of the loaded exogenous ROBs, both in vitro and in vivo. This 3D-bioprinting method holds much promise for bone tissue regeneration in terms of cell engraftment, survival, and ultimately long-term function. PMID- 29593959 TI - Photoinduced Rapid Transformation from Au Nanoagglomerates to Drug-Conjugated Au Nanovesicles. AB - Gold (Au) agglomerates (AGs) are reassembled using Triton X-100 (T) and doxorubicin (D) dissolved in ethanol under 185 nm photoirradiation to form TAuD nanovesicles (NVs) under ambient gas flow conditions. The positively charged Au particles are then electrostatically conjugated with the anionic chains of TD components via a flowing drop (FD) reaction. Photoirradiation of the droplets in a tubular reactor continues the photophysicochemical reactions, resulting in the reassembly of Au AGs and TD into TAuD NVs. The fabricated NVs are electrostatically collected onto a polished aluminum rod in a single-pass configuration. The dispersion of NVs is employed for bioassays to confirm uptake by cells and accumulation in tumors. The chemo-photothermal activity is determined both in vitro and in vivo. Different combinations of components are also used to fabricate NVs using the FD reaction, and these NVs are suitable for gene delivery as well. This newly designed gaseous single-pass process results in the reassembly of Au AGs for incorporation with TD without the need of batch wet chemical reactions, modifications, separations, or purifications. Thus, this process offers an efficient platform for preparing biofunctional Au nanostructures that requires neither complex physicochemical steps nor special storage techniques. PMID- 29593960 TI - Titania-Coated Gold Nano-Bipyramids for Blocking Autophagy Flux and Sensitizing Cancer Cells to Proteasome Inhibitor-Induced Death. AB - Targeting protein degradation is recognized as a valid approach to cancer therapy. The ubiquitin-proteasome system (UPS) and the autophagy-lysosome pathway are two major pathways for intracellular protein degradation. Proteasome inhibitors such as bortezomib are clinically approved for treating malignancies, but to date, they are still unsatisfactory for cancer therapy. This study identifies titania-coated gold nano-bipyramid (NBP/TiO2) nanostructures as an autophagic flux inhibitor, as the smallest NBP/TiO2 nanostructures induce significant autophagosome accumulation in human glioblastoma U-87 MG cells via blocking the autophagosome-lysosome fusion process and inhibiting lysosomal degradation. Further study indicates that NBP/TiO2 nanostructures reduce the intracellular level of mature cathepsin B and directly inhibit the proteolytic activity of cathepsin B, thereby further inhibiting trypsin-like proteolytic activity, which is a potential cotarget for UPS inhibition. NBP/TiO2 nanostructures interact synergistically with bortezomib to suppress the viability of U-87 MG cells, as the combined treatment synergistically induces the intracellular accumulation of ubiquitinated protein and endoplasmic reticulum stress. In addition, photothermal therapy further synergistically reduces the cell viability. In summary, this study suggests that NBP/TiO2 nanostructures function as a promising anticancer agent in combination with proteasome inhibitors. PMID- 29593961 TI - Periodically Self-Pulsating Microcapsule as Programmed Microseparator via ATP Regulated Energy Dissipation. AB - Living systems can experience time-dependent dynamic self-assembly for periodic, adaptive behavior via energy dissipation pathway. Creating in vitro mimics is a daunting mission. Here a "living" giant vesicle system that can perform a periodic pulsating motion using adenosine-5'-triphosphate (ATP)-fuelled dissipative self-assembly is described. This dynamic system is built on transient supramolecular interactions between the polymer and cellular energy currency ATP. The vesicles capturing ATPs will deviate away from equilibrium, leading to an energy ascent that drives a continuous vesicular expansion, until a competitive ATP hydrolysis predominates to break the ATP-polymer interactions and deplete the energy stored in the vesicles, leading to an opposing vesicular contraction. The input of ATP energy can sustain that these vesicles run periodically along this reciprocating expansile-contractile process, resembling a "pulsating" behavior. ATP level can orchestrate the rhythm, amplitude, and lifetime of this biomimetic pulsation. By pre-programming the ATP stimulation protocol, this kind of adaptive microcapsules can function as high-performance microseparators to perform size selective sieving of different nanoparticles through ATP-mediated transmembrane traffic. This man-made system offers a primitive model of time-dependent dynamic self-assembly and may offer new ways to build life-like materials with biomimetic functions. PMID- 29593962 TI - Hierarchically Nanostructured Transition Metal Oxides for Lithium-Ion Batteries. AB - Lithium-ion batteries (LIBs) have been widely used in the field of portable electric devices because of their high energy density and long cycling life. To further improve the performance of LIBs, it is of great importance to develop new electrode materials. Various transition metal oxides (TMOs) have been extensively investigated as electrode materials for LIBs. According to the reaction mechanism, there are mainly two kinds of TMOs, one is based on conversion reaction and the other is based on intercalation/deintercalation reaction. Recently, hierarchically nanostructured TMOs have become a hot research area in the field of LIBs. Hierarchical architecture can provide numerous accessible electroactive sites for redox reactions, shorten the diffusion distance of Li-ion during the reaction, and accommodate volume expansion during cycling. With rapid research progress in this field, a timely account of this advanced technology is highly necessary. Here, the research progress on the synthesis methods, morphological characteristics, and electrochemical performances of hierarchically nanostructured TMOs for LIBs is summarized and discussed. Some relevant prospects are also proposed. PMID- 29593963 TI - Recent Advances on Functionalized Upconversion Nanoparticles for Detection of Small Molecules and Ions in Biosystems. AB - Significant progress on upconversion-nanoparticle (UCNP)-based probes is witnessed in recent years. Compared with traditional fluorescent probes (e.g., organic dyes, metal complexes, or inorganic quantum dots), UCNPs have many advantages such as non-autofluorescence, high chemical stability, large light penetration depth, long lifetime, and less damage to samples. This article focuses on recent achievements in the usage of lanthanide-doped UCNPs as efficient probes for biodetection since 2014. The mechanisms of upconversion as well as the luminescence resonance energy transfer process is introduced first, followed by a detailed summary on the recent researches of UCNP-based biodetections including the detection of inorganic ions, gas molecules, reactive oxygen species, and thiols and hydrogen sulfide. PMID- 29593964 TI - TiO2 Phase Junction Electron Transport Layer Boosts Efficiency of Planar Perovskite Solar Cells. AB - In the planar perovskite solar cells (PSCs), the electron transport layer (ETL) plays a critical role in electron extraction and transport. Widely utilized TiO2 ETLs suffer from the low conductivity and high surface defect density. To address these problems, for the first time, two types of ETLs based on TiO2 phase junction are designed and fabricated distributed in the opposite space, namely anatase/rutile and rutile/anatase. The champion efficiency of PSCs based on phase junction ETL is over 15%, which is much higher than that of cells with single anatase (9.8%) and rutile (11.8%) TiO2 as ETL. The phase junction based PSCs also demonstrated obviously reduced hysteresis. The enhanced performance is discussed and mainly ascribed to the excellent capability of carrier extraction, defect passivation, and reduced recombination at the ETL/perovskite interface. This work opens a new phase junction ETL strategy toward interfacial energy band manipulation for improved PSC performance. PMID- 29593965 TI - Superlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes. AB - 2D or 3D layered materials, such as graphene, graphite, and molybdenum disulfide, usually exhibit superlubricity properties when sliding occurs between the incommensurate interface lattices. This study reports the superlubricity between graphite and silica under ambient conditions, induced by the formation of multiple transferred graphene nanoflakes on the asperities of silica surfaces after the initial frictional sliding. The friction coefficient can be reduced to as low as 0.0003 with excellent robustness and is independent of the surface roughness, sliding velocities, and rotation angles. The superlubricity mechanism can be attributed to the extremely weak interaction and easy sliding between the transferred graphene nanoflakes and graphite in their incommensurate contact. This finding has important implications for developing approaches to achieve superlubricity of layered materials at the nanoscale by tribointeractions. PMID- 29593966 TI - Self-Assembled Biomolecular 1D Nanostructures for Aqueous Sodium-Ion Battery. AB - Aqueous sodium-ion battery of low cost, inherent safety, and environmental benignity holds substantial promise for new-generation energy storage applications. However, the narrow potential window of water and the enlarged ionic radius because of hydration restrict the selection of electrode materials used in the aqueous electrolyte. Here, inspired by the efficient redox reaction of biomolecules during cellular energy metabolism, a proof of concept is proposed that the redox-active biomolecule alizarin can act as a novel electrode material for the aqueous sodium-ion battery. It is demonstrated that the specific capacity of the self-assembled alizarin nanowires can reach as high as 233.1 mA h g-1, surpassing the majority of anodes ever utilized in the aqueous sodium-ion batteries. Paired with biocompatible and biodegradable polypyrrole, this full battery system shows excellent sodium storage ability and flexibility, indicating its potential applications in wearable electronics and biointegrated devices. It is also shown that the electrochemical properties of electrodes can be tailored by manipulating naturally occurring 9,10-anthroquinones with various substituent groups, which broadens application prospect of biomolecules in aqueous sodium-ion batteries. PMID- 29593967 TI - Redox-Active Separators for Lithium-Ion Batteries. AB - A bilayered cellulose-based separator design is presented that can enhance the electrochemical performance of lithium-ion batteries (LIBs) via the inclusion of a porous redox-active layer. The proposed flexible redox-active separator consists of a mesoporous, insulating nanocellulose fiber layer that provides the necessary insulation between the electrodes and a porous, conductive, and redox active polypyrrole-nanocellulose layer. The latter layer provides mechanical support to the nanocellulose layer and adds extra capacity to the LIBs. The redox active separator is mechanically flexible, and no internal short circuits are observed during the operation of the LIBs, even when the redox-active layer is in direct contact with both electrodes in a symmetric lithium-lithium cell. By replacing a conventional polyethylene separator with a redox-active separator, the capacity of the proof-of-concept LIB battery containing a LiFePO4 cathode and a Li metal anode can be increased from 0.16 to 0.276 mA h due to the capacity contribution from the redox-active separator. As the presented redox-active separator concept can be used to increase the capacities of electrochemical energy storage systems, this approach may pave the way for new types of functional separators. PMID- 29593968 TI - Engineering a Tumor Microenvironment-Mimetic Niche for Tissue Regeneration with Xenogeneic Cancer Cells. AB - The insufficient number of cells suitable for transplantation is a long-standing problem to cell-based therapies aimed at tissue regeneration. Xenogeneic cancer cells (XCC) may be an alternative source of therapeutic cells, but their transplantation risks both immune rejection and unwanted spreading. In this study, a strategy to facilitate XCC transplantation is reported and their spreading in vivo is confined by constructing an engineering matrix that mimics the characteristics of tumor microenvironment. The data show that this matrix, a tumor homogenate-containing hydrogel (THAG), successfully creates an immunosuppressive enclave after transplantation into immunocompetent mice. XCC of different species and tissue origins seeded into THAG survive well, integrated with the host and developed the intrinsic morphology of the native tissue, without being eliminated or spreading out of the enclave. Most strikingly, immortalized human hepatocyte cells and rat beta-cells loaded into THAG exert the physiological functions of the human liver and rat pancreas islets, respectively, in the mouse body. This study demonstrates a novel and feasible approach to harness the unique features of tumor development for tissue transplantation and regenerative medicine. PMID- 29593969 TI - Enabling Photon Upconversion and Precise Control of Donor-Acceptor Interaction through Interfacial Energy Transfer. AB - Upconverting materials have achieved great progress in recent years, however, it remains challenging for the mechanistic research on new upconversion strategy of lanthanides. Here, a novel and efficient strategy to realize photon upconversion from more lanthanides and fine control of lanthanide donor-acceptor interactions through using the interfacial energy transfer (IET) is reported. Unlike conventional energy-transfer upconversion and recently reported energy-migration upconversion, the IET approach is capable of enabling upconversions from Er3+, Tm3+, Ho3+, Tb3+, Eu3+, Dy3+ to Sm3+ in NaYF4- and NaYbF4-based core-shell nanostructures simultaneously. Applying the IET in a Nd-Yb coupled sensitizing system can also enable the 808/980 nm dual-wavelength excited upconversion from a single particle. More importantly, the construction of IET concept allows for a fine control and manipulation of lanthanide donor-acceptor interactions and dynamics at the nanometer-length scale by establishing a physical model upon an interlayer-mediated nanostructure. These findings open a door for the fundamental understanding of the luminescence dynamics involving lanthanides at nanoscale, which would further help conceive new scientific concepts and control photon upconversion at a single lanthanide ion level. PMID- 29593970 TI - Compositionally Graded Absorber for Efficient and Stable Near-Infrared Transparent Perovskite Solar Cells. AB - Compositional grading has been widely exploited in highly efficient Cu(In,Ga)Se2, CdTe, GaAs, quantum dot solar cells, and this strategy has the potential to improve the performance of emerging perovskite solar cells. However, realizing and maintaining compositionally graded perovskite absorber from solution processing is challenging. Moreover, the operational stability of graded perovskite solar cells under long-term heat/light soaking has not been demonstrated. In this study, a facile partial ion-exchange approach is reported to achieve compositionally graded perovskite absorber layers. Incorporating compositional grading improves charge collection and suppresses interface recombination, enabling to fabricate near-infrared-transparent perovskite solar cells with power conversion efficiency of 16.8% in substrate configuration, and demonstrate 22.7% tandem efficiency with 3.3% absolute gain when mechanically stacked on a Cu(In,Ga)Se2 bottom cell. Non-encapsulated graded perovskite device retains over 93% of its initial efficiency after 1000 h operation at maximum power point at 60 degrees C under equivalent 1 sun illumination. The results open an avenue in exploring partial ion-exchange to design graded perovskite solar cells with improved efficiency and stability. PMID- 29593971 TI - In Situ Synthesis of Vertical Standing Nanosized NiO Encapsulated in Graphene as Electrodes for High-Performance Supercapacitors. AB - NiO is a promising electrode material for supercapacitors. Herein, the novel vertically standing nanosized NiO encapsulated in graphene layers (G@NiO) are rationally designed and synthesized as nanosheet arrays. This unique vertical standing structure of G@NiO nanosheet arrays can enlarge the accessible surface area with electrolytes, and has the benefits of short ion diffusion path and good charge transport. Further, an interconnected graphene conductive network acts as binder to encapsulate the nanosized NiO particles as core-shell structure, which can promote the charge transport and maintain the structural stability. Consequently, the optimized G@NiO hybrid electrodes exhibit a remarkably enhanced specific capacity up to 1073 C g-1 and excellent cycling stability. This study provides a facial strategy to design and construct high-performance metal oxides for energy storage. PMID- 29593972 TI - Intrinsically High Thermoelectric Performance in AgInSe2 n-Type Diamond-Like Compounds. AB - Diamond-like compounds are a promising class of thermoelectric materials, very suitable for real applications. However, almost all high-performance diamond-like thermoelectric materials are p-type semiconductors. The lack of high-performance n-type diamond-like thermoelectric materials greatly restricts the fabrication of diamond-like material-based modules and their real applications. In this work, it is revealed that n-type AgInSe2 diamond-like compound has intrinsically high thermoelectric performance with a figure of merit (zT) of 1.1 at 900 K, comparable to the best p-type diamond-like thermoelectric materials reported before. Such high zT is mainly due to the ultralow lattice thermal conductivity, which is fundamentally limited by the low-frequency Ag-Se "cluster vibrations," as confirmed by ab initio lattice dynamic calculations. Doping Cd at Ag sites significantly improves the thermoelectric performance in the low and medium temperature ranges. By using such high-performance n-type AgInSe2-based compounds, the diamond-like thermoelectric module has been fabricated for the first time. An output power of 0.06 W under a temperature difference of 520 K between the two ends of the module is obtained. This work opens a new window for the applications using the diamond-like thermoelectric materials. PMID- 29593973 TI - Molybdenum Carbide Nanoparticles Coated into the Graphene Wrapping N-Doped Porous Carbon Microspheres for Highly Efficient Electrocatalytic Hydrogen Evolution Both in Acidic and Alkaline Media. AB - Molybdenum carbide (Mo2C) is recognized as an alternative electrocatalyst to noble metal for the hydrogen evolution reaction (HER). Herein, a facile, low cost, and scalable method is provided for the fabrication of Mo2C-based eletrocatalyst (Mo2C/G-NCS) by a spray-drying, and followed by annealing. As prepared Mo2C/G-NCS electrocatalyst displays that ultrafine Mo2C nanopartilces are uniformly embedded into graphene wrapping N-doped porous carbon microspheres derived from chitosan. Such designed structure offer several favorable features for hydrogen evolution application: 1) the ultrasmall size of Mo2C affords a large exposed active sites; 2) graphene-wrapping ensures great electrical conductivity; 3) porous structure increases the electrolyte-electrode contact points and lowers the charge transfer resistance; 4) N-dopant interacts with H+ better than C atoms and favorably modifies the electronic structures of adjacent Mo and C atoms. As a result, the Mo2C/G-NCS demonstrates superior HER activity with a very low overpotential of 70 or 66 mV to achieve current density of 10 mA cm-2, small Tafel slope of 39 or 37 mV dec-1, respectively, in acidic and alkaline media, and high stability, indicating that it is a great potential candidate as HER electrocatalyst. PMID- 29593974 TI - The Dawn of Lead-Free Perovskite Solar Cell: Highly Stable Double Perovskite Cs2AgBiBr6 Film. AB - Recently, lead-free double perovskites have emerged as a promising environmentally friendly photovoltaic material for their intrinsic thermodynamic stability, appropriate bandgaps, small carrier effective masses, and low exciton binding energies. However, currently no solar cell based on these double perovskites has been reported, due to the challenge in film processing. Herein, a first lead-free double perovskite planar heterojunction solar cell with a high quality Cs2AgBiBr6 film, fabricated by low-pressure assisted solution processing under ambient conditions, is reported. The device presents a best power conversion efficiency of 1.44%. The preliminary efficiency and the high stability under ambient condition without encapsulation, together with the high film quality with simple processing, demonstrate promise for lead-free perovskite solar cells. PMID- 29593975 TI - Ultraconformable Temporary Tattoo Electrodes for Electrophysiology. AB - Electrically interfacing the skin for monitoring personal health condition is the basis of skin-contact electrophysiology. In the clinical practice the use of stiff and bulky pregelled or dry electrodes, in contrast to the soft body tissues, imposes severe restrictions to user comfort and mobility while limiting clinical applications. Here, in this work dry, unperceivable temporary tattoo electrodes are presented. Customized single or multielectrode arrays are readily fabricated by inkjet printing of conducting polymer onto commercial decal transfer paper, which allows for easy transfer on the user's skin. Conformal adhesion to the skin is provided thanks to their ultralow thickness (<1 um). Tattoo electrode-skin contact impedance is characterized on short- (1 h) and long term (48 h) and compared with standard pregelled and dry electrodes. The viability in electrophysiology is validated by surface electromyography and electrocardiography recordings on various locations on limbs and face. A novel concept of tattoo as perforable skin-contact electrode, through which hairs can grow, is demonstrated, thus permitting to envision very long-term recordings on areas with high hair density. The proposed materials and patterning strategy make this technology amenable for large-scale production of low-cost sensing devices. PMID- 29593976 TI - Hollow TiO2@Co9S8 Core-Branch Arrays as Bifunctional Electrocatalysts for Efficient Oxygen/Hydrogen Production. AB - Designing ever more efficient and cost-effective bifunctional electrocatalysts for oxygen/hydrogen evolution reactions (OER/HER) is greatly vital and challenging. Here, a new type of binder-free hollow TiO2@Co9S8 core-branch arrays is developed as highly active OER and HER electrocatalysts for stable overall water splitting. Hollow core-branch arrays of TiO2@Co9S8 are readily realized by the rational combination of crosslinked Co9S8 nanoflakes on TiO2 core via a facile and powerful sulfurization strategy. Arising from larger active surface area, richer/shorter transfer channels for ions/electrons, and reinforced structural stability, the as-obtained TiO2@Co9S8 core-branch arrays show noticeable exceptional electrocatalytic performance, with low overpotentials of 240 and 139 mV at 10 mA cm-2 as well as low Tafel slopes of 55 and 65 mV Dec-1 for OER and HER in alkaline medium, respectively. Impressively, the electrolysis cell based on the TiO2@Co9S8 arrays as both cathode and anode exhibits a remarkably low water splitting voltage of 1.56 V at 10 mA cm-2 and long-term durability with no decay after 10 d. The versatile fabrication protocol and smart branch-core design provide a new way to construct other advanced metal sulfides for energy conversion and storage. PMID- 29593977 TI - Smart Construction of Integrated CNTs/Li4Ti5O12 Core/Shell Arrays with Superior High-Rate Performance for Application in Lithium-Ion Batteries. AB - Exploring advanced high-rate anodes is of great importance for the development of next-generation high-power lithium-ion batteries (LIBs). Here, novel carbon nanotubes (CNTs)/Li4Ti5O12 (LTO) core/shell arrays on carbon cloth (CC) as integrated high-quality anode are constructed via a facile combined chemical vapor deposition-atomic layer deposition (ALD) method. ALD-synthesized LTO is strongly anchored on the CNTs' skeleton forming core/shell structures with diameters of 70-80 nm the combined advantages including highly conductive network, large surface area, and strong adhesion are obtained in the CC-LTO@CNTs core/shell arrays. The electrochemical performance of the CC-CNTs/LTO electrode is completely studied as the anode of LIBs and it shows noticeable high-rate capability (a capacity of 169 mA h g-1 at 1 C and 112 mA h g-1 at 20 C), as well as a stable cycle life with a capacity retention of 86% after 5000 cycles at 10 C, which is much better than the CC-LTO counterpart. Meanwhile, excellent cycling stability is also demonstrated for the full cell with LiFePO4 cathode and CC CNTs/LTO anode (87% capacity retention after 1500 cycles at 10 C). These positive features suggest their promising application in high-power energy storage areas. PMID- 29593978 TI - Quantitative Assessments of Mechanical Responses upon Radial Extracorporeal Shock Wave Therapy. AB - Although radial extracorporeal shock wave therapy (rESWT) has been widely used to treat orthopedic disorders with promising clinical results, rESWT largely relies on clinicians' personal experiences and arbitrary judgments, without knowing relationships between administration doses and effective doses at target sites. In fact, practitioners lack a general and reliable way to assess propagation and distribution of pressure waves inside biological tissues quantitatively. This study develops a methodology to combine experimental measurements and computational simulations to obtain pressure fields from rESWT through calibrating and validating computational models with experimental measurements. Wave pressures at the bottom of a petri dish and inside biological tissues are measured, respectively, by attaching and implanting flexible membrane sensors. Detailed wave dynamics are simulated through explicit finite element analyses. The data decipher that waves from rESWT radiate directionally and can be modeled as acoustic waves generated from a vibrating circular piston. Models are thus established to correlate pressure amplitudes at the bottom of petri dishes and in the axial direction of biological tissues. Additionally, a pilot simulation upon rESWT for human lumbar reveals a detailed and realistic pressure field mapping. This study will open a new avenue of personalized treatment planning and mechanism research for rESWT. PMID- 29593979 TI - The association between pre-hospital antibiotic therapy and subsequent in hospital mortality in adults presenting with community-acquired pneumonia: an observational study. AB - Background: The majority of patients with community acquired-pneumonia (CAP) are treated in primary care and the mortality in this group is very low. However, a small but significant proportion of patients who begin treatment in the community subsequently require admission due to symptomatic deterioration. This study compared patients who received community antibiotics prior to admission to those who had not, and looked for associations with clinical outcomes. Methods: This study analysed the Advancing Quality (AQ) Pneumonia database of patients admitted with CAP to 9 acute hospitals in the northwest of England over a 12-month period. Results: There were 6348 subjects (mean age 72 [SD 16] years; gender ratio 1:1) admitted with CAP, of whom 17% had been pre-treated with antibiotics. The in hospital mortality was 18.6% for the pre-treatment group compared to 13.2% in the "antibiotic naive" group (p < 0.001). On multivariate analysis, age, male gender and antibiotic pre-treatment were predictors of in-hospital mortality along with a history of cerebrovascular accident, congestive cardiac failure, dementia, renal disease and cancer. After adjustment for CURB-65 score, age, co-morbidities and pre-treatment with antibiotics remained as independent risk factors for in hospital mortality (OR 1.43, 95% CI 1.19-1.71). Conclusion: CAP patients admitted to hospital were more likely to die during admission if they had received antibiotics for the same illness pre-admission. Future studies should endeavor to determine the mechanisms underlying this association, such as microbiological factors and the role of comorbidities. Patients hospitalized with CAP despite prior antibiotic treatment in the community require close monitoring. PMID- 29593980 TI - Anatomic Posterolateral Corner Reconstruction With Autografts. AB - Anatomic posterolateral corner reconstruction reproduces 3 main structures: the lateral collateral ligament, the popliteofibular ligament, and the popliteus tendon. The LaPrade technique reproduces all 3 main stabilizers. However, it requires a long graft, limiting its indication to clinical settings in which allograft tissue is available. We propose a surgical procedure that is a modification of the LaPrade technique using the same tunnel placement, hamstring autografts, and biceps augmentation when necessary. It relies on artificial graft lengthening provided by the loop of the suspensory fixation device fixed at the anterior tibial cortex. The final reconstruction reproduces the popliteus tendon with the bulkiest end of the semitendinosus; the popliteofibular ligament with a strand of the semitendinosus and a strand of the gracilis; and the lateral collateral ligament with a strand of the semitendinosus and a strand of the gracilis, which can also be augmented with a biceps strip. PMID- 29593981 TI - Giant cystic degeneration of a uterine leiomyoma in a patient with autosomal dominant polycystic kidney disease. AB - Objective: To report the management of a large uterine leiomyoma with diffuse cystic degeneration in a patient with autosomal dominant polycystic kidney disease (ADPKD). Design: Case Report. Setting: Cleveland Clinic Florida, Department of Gynecology, Section of Minimally Invasive Gynecologic surgery, Weston Florida. Patients: A 52-year old woman with ADPKD with a large abdominal mass, abnormal uterine bleeding and symptomatic anemia. Imaging revealed a giant intramural cystic lesion of the uterus compressing the inferior vena cava. Interventions: Uterine artery embolization and blood transfusion followed by a computed tomography guided cyst aspiration were performed on admission to alleviate anemia and abdominal pain and distension. Total laparoscopic hysterectomy with bilateral salpingectomy was performed in an outpatient setting. Main Outcome Measures: Management of large cystic degeneration of leiomyoma. Results: Normal recovery from definitive surgery. Surgical pathology confirmed a benign, cystically dilated leiomyoma. Conclusion: This case demonstrates the management of giant intramural cyst lesion of the uterus using a minimally invasive surgical approach, as opposed to emergency surgery via laparotomy. Capsule: Large uterine leiomyoma with diffuse cystic degeneration in a patient with autosomal dominant polycystic kidney disease, in which step-wise treatments allows successful minimally invasive hysterectomy. PMID- 29593982 TI - Vaginal evisceration as rare but a serious obstetric complication: A case series. AB - Introduction: Gut prolapse through vagina is rare complication with only few cases reported in the literature. This article highlights untrained professionals induced obstetrical trauma as a cause of vaginal evisceration leading to serious but preventable complications. Presentation of Case: Case 1: A 27 years old female, P2L0, had full term vaginal delivery of an IUD baby and presented 4 days later with small bowel evisceration through posterior vaginal wall. Case 2: A 24 years old female, P1A1 had underwent unsafe abortion and presented in shock, with small bowel evisceration through anterior uterine wall. Case 3: A 26 years female, P2A1, underwent evacuation for incomplete abortion and presented with omental prolapse through anterior uterine wall. Discussion: Obstetrical trauma with associated evisceration of intraabdominal contents is a potentially serious complication that requires surgical intervention. General awareness may decrease these unsafe practices and thus would have impact in reducing maternal morbidity and mortality. PMID- 29593983 TI - Intrapartal resection of the double cervix and longitudinal vaginal septum after hysteroscopic resection of the complete uterine septum, resulting in a term vaginal delivery: A case report. AB - Objective: To report a rare uterine anomaly of a septate uterus, double cervix and double vagina in patient who conceived spontaneously and delivered vaginaly. Design: Case report. Setting: Department of Obstetrics and Gynecology, Zagreb University School of Medicine, Clinical Hospital "Sveti Duh", Zagreb, Croatia. Patients: A 34-year-old nulligravida who underwent clinical, radiological, surgical and intrapartal workup. Interventions: Clinical examination and intrapartal surgical resection of vaginal septum followed by vaginal delivery. Main Outcome Measures: Description and treatment for a rare Mullerian anomaly and a subsequent literature search. Results: Successful intrapartal resection of longitudinal vaginal septum and double cervix followed by vaginal delivery without complication. Conclusions: Reconstructive surgical procedures may be considered for providing spontaneous pregnancies and intrapartal surgical technique could be taken into consideration in order to prevent unnecessary cesarean sections, upon strict estimation of the obstetrician. PMID- 29593984 TI - A Bartholin's gland with nodules and cysts bathed in mucus. AB - The most common pathology of the Bartholin's gland is with its draining duct. Marsupialisation or fistulisation are the most common therapies. In some women, the clinical problem is with the Bartholin's gland itself, being hyperplasia with or without duct rupture in the subcutaneous tissue. Presenting symptoms and signs of nodular hyperplasia are pain and (nodular or diffuse) swelling especially during sexual arousal, or simply a symptomless mass. During surgery, the striking features are subcutaneous free-floating mucus and nodular enlargement 'deep' in the labium majus. The optimal surgical approach is an excision through an incision alongside the labiocrural fold. We describe three cases to provide insight into the various clinical presentations and management problems. Nodular hyperplasia of Bartholin's gland is easily misdiagnosed because of its rare occurrence and diversity of signs and symptoms. An unusual presentation or clinical course of disease may indicate nodular hyperplasia. PMID- 29593985 TI - Full term viable secondary broad ligament pregnancy - A rare case. AB - Broad ligament pregnancy is also known as inter ligamentous pregnancy which is a rare form of ectopic pregnancy. Very few successful live births have been reported in this condition, where such pregnancies reached term and with live birth of a baby. A case of 28 year old primigravida of 35 weeks gestation with oligoamnios was referred to our hospital. A right broad ligament pregnancy was confirmed after an ultrasound and an MRI. She was taken up for surgery and an incision was given on the anterior leaf of the broad ligament and a male live fetus was extracted. Placenta was found on the posterior leaf of the broad ligament and it was removed without any undue haemorrhage. Uterus was lying medial to the sac and was around ten weeks in size. Both mother and baby were discharged on seventh postoperative day in good health condition. PMID- 29593986 TI - Spontaneous acute intussusception in a pregnant woman. AB - Acute intussusception in adults is rare and particularly so in pregnant women. Its incidence ranges from 0.067% to 0.0015% (Choi et al., 2005 Choi et al. (2005) [1]). The non-specific presenting symptoms may be attributed to the pregnancy itself, making the diagnosis difficult. When it happens, however, it causes considerable morbidity and mortality for the pregnant woman and the fetus. In adults, such intussusceptions are mainly secondary to an intestinal disease and frequently a tumor. We present the case of a 21-year-old pregnant woman who was diagnosed of spontaneous acute intussusception at nine weeks of gestation and therapeutic management. PMID- 29593987 TI - Luteal phase support for documented failure of placental steroidogenesis: A case report. AB - Objective: To report a case of a habitual aborter that had a pregnancy reach near term and successfully delivered a viable female infant. Design: Report of a unique case of a G10P1 that was successfully able to maintain a pregnancy by maintaining serum levels of estradiol and progesterone at or above 200 pg/dL and 25 ng/dL respectively. This case provides a benchmark for exogenous support of estradiol and progesterone throughout pregnancy. Setting: A private advanced reproductive center. Patient: 39-year-old G10P1091 diagnosed to have antiphospholipid syndrome but continued to have continuous miscarriages despite accepted treatment. In addition, 8 products of conception were sent for cytogenetic testing and all were found to be normal. Interventions: Examination, laboratory studies, imaging, clinical judgment, and knowledge of previous treatment failures were used to guide the treatment of this patient. Fertility was achieved with continuous supplementation of progesterone, estrogen, LMW heparin, and prednisone. Main Outcome Measure: Delivery of viable infant. Results: This advanced reproductive age woman had three subsequent pregnancies. While compliant with our prescribed protocol, the patient successfully carried two pregnancies to viability. Conclusion: Clinicians should be alert to the possibility of a luteal phase defect when a patient presents with recurrent fertility problems and multiple spontaneous abortions.

Setting: Tertiary referral center, King Fahad Medical City. Patients: A 23-year-old nulligravida with polycystic ovarian syndrome and primary infertility underwent oocyte retrieval for intracytoplasmic sperm injection (ICSI), and developed Fowler's syndrome (FS). Interventions: Intermittent self catheterization, insertion of sacral neuromodulator (SNM). Main outcome measures: Restoration of normal voiding. Results: Immediate resolution of patient's symptoms after installation of SNM. Conclusions: Fowler's syndrome, although rare, may occur post routine oocyte retrieval; Successful restoration of voiding and resolution of symptoms is possible with SNM installation in similar patients. PMID- 29593989 TI - Postoperative care of symphysiotomy performed for severe shoulder dystocia with fetal demise. AB - Background: Shoulder dystocia is an obstetric emergency which occurs in 0.2-3% of all births ACOG Committee on Practice Bulletins-Obstetrics and The American College of Obstetrician and Gynecologists (2002) . Symphysiotomy is a treatment option reserved primarily for developing countries where mortality rates of Cesarean delivery are 1-2% Monjok et al. (2013) . Case: A G3P2002 with a history of two prior vaginal deliveries had a term delivery complicated by a severe shoulder dystocia. She underwent emergent symphysiotomy at an outside institution, with delivery of a dead macrosomic infant. She was transferred to our tertiary care center for further care. Conclusion: Symphysiotomy is rarely performed in the United States. We submit our postoperative management to add to the literature of this rarely performed obstetric intervention. Precis: Symphysiotomy for severe shoulder dystocia is rarely utilized in the United States. We describe a case of symphysiotomy done for severe shoulder dystocia at an outside institution, and the patient's subsequent care at our institution. PMID- 29593990 TI - Successful pregnancy located in a uterine cesarean scar: A case report. AB - Cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy. Because CSP carries a high risk of uterine rupture and life-threatening bleeding, the pregnancy should be terminated upon confirmation of diagnosis. There have been few reports of CSP with successful delivery. We present a case of CSP under expectant management, with delivery via planned cesarean section at 35 weeks of gestation. This report suggests that successful pregnancy outcome can be achieved in some women with uterine cesarean scar, but further analysis and additional studies are required in order to describe the optimal protocol of expectant management in CSP. PMID- 29593991 TI - Uterine rupture in a primigravid patient with an unscarred bicornuate uterus at term. AB - Background: Uterine rupture of an unscarred primigravid uterus is an exceedingly rare event. Cases of spontaneous rupture of an unscarred bicornuate uterus have been reported, but typically occur in the first or second trimester. Case: A 28 year-old primigravida at 37 weeks gestation with a known bicornuate uterus and no prior surgery underwent an emergent cesarean section after presenting with severe abdominal pain and signs of fetal compromise. She was found to have a uterine rupture with the fetus free in the abdomen accompanied by a large hemoperitoneum. Both mother and baby did well postoperatively. Conclusion: Bicornuate uterus may be an independent risk factor for uterine rupture, which can occur in primigravid patients and at any gestation. PMID- 29593992 TI - Intracavitary deposits on Essure(r) hysteroscopic sterilization devices: A case report. AB - Objective: To study the composition of intracavitary deposits on Essure(r) hysteroscopic sterilization devices. Design: Case report. Setting: Reproductive Medicine and Gynecology department of a University Hospital. Patients: A 39 years old patient presenting with a request for surgical removal of Essure(r) sterilization devices. Diagnostic hysteroscopy showed a crystal like white deposit attached to one of the devices. Intervention: Diagnostic hysteroscopy and surgical removal of Essure(r) devices was performed. The deposits were collected and infrared spectroscopy analysis was performed. Main Outcome Measure: Chemical composition of the deposits attached to the device. Results: Infrared spectroscopy of the material showed patterns conclusive with calcite (calcium carbonate, CaCO3). Conclusion: Until now, it is not clear if there is a relationship between reported complaints and formation of calcite deposits on Essure(r). Capsule: Infrared spectroscopy of deposits on Essure(r) devices showed a pattern conclusive with calcite. The relationship between reported complaints and the formation of calcite deposits on Essure(r) remains unclear. PMID- 29593993 TI - Fetal primary hydrothorax with spontaneous resolution. AB - Fetal primary hydrothorax is a rare congenital anomaly with an estimated incidence of 1:10.000-15.000 pregnancies, with an unpredictable clinical course, ranging from spontaneous resolution to fetal death. We present a case of a unilateral fetal pleural effusion identified at 35th gestational week. A 37 year old woman (G2P1) presented to our routine term pregnancy evaluation. The pregnancy had been otherwise uneventful. At ecographic evaluation a large anechogenic fluid collection was identified in the right fetal hemithorax, with atelectasis of right lung, displacing the heart and mediastinal structures to the contralateral hemithorax. Hydramnios was also identified. No other structural abnormalities were detected, as no signs of hydrops. Fetal biometry was compatible with gestational age. Fetal ecochardiogram was structurally and functionally normal. Doppler evaluation of the peak systolic velocity in the middle cerebral artery was normal. Screening for congenital infections was negative. Complete blood cell count, blood type and antibody screening rulled-out immune hydrops. Karyotype analysis was not performed as family decision. Serial ecographic re-evaluations showed a progressive volume decrease and at the 38th week there was total resolution of the effusion. A C-section was performed at the 39th week. A live female infant was born weighing 3205 g, with no need of ventilatory support. One year post-partum follow-up evaluation confirmed the child was healthy. Spontaneous regression has been reported to occur in 9-22% of primary fetal hydrothoraxes, but the features predicting a better prognosis remain difficult to define. Unilateral effusion, spontaneous resolution and absence of hydrops at the age of diagnosis seem to be indicators of better outcome.

AB - Background: Severe vulvar edema is a rare entity occurring with ovarian hyperstimulation syndrome. This edema can be incapacitating; causing pain and limited patient mobility. With the usual conservative approach, vulvar edema can take several days to resolve. Aim: The aim of this case report is to describe the use of local myrrh for the management of severe vulvar edema associated with ovarian hyperstimulation syndrome. Case Presentation: 29-year-old female with severe vulvar edema associated with ovarian hyperstimulation syndrome. Conclusion: Local myrrh application for severe vulvar edema in ovarian hyperstimulation syndrome resulted in substantial improvement, and with further studies, myrrh could be used as an option for the management of vulvar edema. PMID- 29593996 TI - Trauma-induced delivery: A case report. AB - The term "birth trauma" is one that is well ingrained into the lexicon of medical providers. There is ample information of the types of injuries that are incurred during the birth process. However, there is no uniformed term for the process of an unforeseen act that leads to a precipitous birth. We would like to show a case report of such an act. The infant's injuries were sustained while in utero and the trauma induced a medical team to deliver the infant due to non-reassuring heart tones. Also, we would like to introduce the term of "trauma-induced delivery" into the medical literature as a way to describe similar types of deliveries that are influenced by factors related to physical forces applied to the mother's body, either intentional or unintentional. PMID- 29593995 TI - Late-onset endometrial ablation failure. AB - Endometrial ablation, first reported in the 19th century, has gained wide acceptance in the gynecologic community as an important tool for the management of abnormal uterine bleeding when medical management has been unsuccessful or contraindicated. The introduction of global endometrial ablation (GEA) devices beginning in 1997 has provided unsurpassed safety addressing many of the concerns associated with their resectoscopic predecessors. As of this writing the GEA market has surpassed a half-million devices in the United States per annum and has an expected compound annual growth rate (CAGR) projected to be 5.5% from 2016 to 2024. While the short term safety and efficacy of these devices has been reported in numerous clinical trials we only recently are becoming aware of the high incidence of late-onset endometrial ablation failures (LOEAFs) associated with these procedures. Currently, about a quarter of women who undergo a GEA procedure will eventually require a hysterectomy while an unknown number have less than satisfactory results. In order to reduce these suboptimal outcomes physicians must better understand the etiology and risk factors that predispose a patient toward the development of LOEAF as well as current knowledge of patient and procedure selection for EA as well as treatment options for these delayed complications. PMID- 29593997 TI - Hereditary leiomyomatosis and renal cell cancer: Cutaneous lesions & atypical fibroids. AB - Objective: To report a diagnosis of hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome following initial presentation with multiple cutaneous lesions. Design: Case report. Design classification: N/A. Setting: Academic tertiary care center. Patients: 27-year-old nulligravid woman who presented with multiple red-brown lesions on her skin found to have cutaneous and uterine leiomyoma. Interventions: Biopsy of cutaneous lesions and fertility sparing robot assisted laparoscopic myomectomy (RALM). Main outcome measuress: Histological assessment of uterine leiomyoma. Resultss: Pathologic examination of uterine leiomyoma revealed diffuse atypia and fumarate hydratase loss phenotype concerning for genetic syndrome. Follow-up DNA sequencing via Sanger sequencing confirmed a pathogenetic R2333H mutation consistent with HLRCC. Conclusions: Consideration of HLRCC on differential diagnosis when patients present with cutaneous nodules and atypical or early onset uterine leiomyoma provides opportunity for early surveillance, family member testing, and more thoughtful surgical planning. Precis: 27-year-old woman with multiple cutaneous lesions is found to have uterine leiomyomas and undergoes robotic myomectomy. Genetic testing of uterine leiomyomas reveals mutation in fumarate hydratase, etiologic in hereditary leiomyomatosis and renal cell cancer (HLRCC).

PMID- 29594000 TI - Nonimmune hydrops fetalis due to autosomal recessive hereditary spherocytosis. AB - Background: Hereditary spherocytosis is the most common form of inherited hemolytic anemia and is characterized by a structural defect in the RBC membrane. The disorder is commonly inherited in an autosomal dominant fashion and leads to a mild to moderate anemia. The autosomal recessive form of hereditary spherocytosis is rarely reported in association with fetal anemia and hydrops fetalis. Case: A 25 year old G5 P2112 at 25 2/7 weeks gestation presents with severe fetal anemia and nonimmune hydrops fetalis requiring multiple fetal intrauterine transfusions. After delivery, the neonate required several double volume exchange transfusions and ultimately was diagnosed with autosomal recessive hereditary spherocytosis weeks after birth. The neonate was identified to have a rare homozygous genetic mutation, SPTA1c.6154delG, which leads to absent production of normal alpha-spectrin. Conclusion: The case highlights the importance of considering less common genetic mutations involving the RBC structural proteins when patients present with severe fetal anemia and nonimmune hydrops fetalis. PMID- 29594001 TI - Urinary ascites in late onset of bladder injury post laparoscopic hysterectomy. AB - Urinary tract injuries are unfortunate complications of pelvic surgery. With the increasing popularity of minimally invasive surgery, a thorough understanding of electrosurgical instrumentation and their thermal spread is important to reduce patient injuries. The index patient was a 50 year old woman who underwent a supracervical hysterectomy 5 years prior to her presentation with pelvic pain and dysuria. When her symptoms failed to improve despite antibiotic and analgesic therapy, an abdominal CT scan revealed an ovarian cyst and ascites. A subsequent laparoscopy disclosed the presence of a bladder fistula and a diagnosis of urinary ascites was made. The patient then underwent a subsequent bladder fistula repair. Vesicoperitoneal fistulae (VPF) are rare and should be included in the differential diagnosis of the patient with acute onset ascites following gynecologic surgery. This case is the first case report of a VPF occurring 5 years following surgery. PMID- 29594002 TI - Obstetric Management of Delayed-Interval Delivery. AB - The delayed-interval delivery is a rare, flexible and complex procedure. In light of these facts, there is no consensus on the best approach to achieve it successfully. This case report is of an asynchronous delivery, in a twin pregnancy, with a 32-day interval between births of siblings. Our obstetric management at a critical gestational age improved the outcome of the second newborn. The probability of success of delayed-interval delivery depends on the proper selection of the candidates, the appropriate active management and the continuous monitoring for early detection of complications. PMID- 29594003 TI - Snake bite in third trimester of pregnancy with systemic envenomation and delivery of a live baby in a low resource setting: A case report. AB - Background: Snake bite in the third trimester of pregnancy with late presentation, systemic envenomation; disseminated intravascular coagulopathy and delivery of a live neonate is uncommon in a low resource setting. Case: We present a 22 year old unbooked Gravida 3 Para 1+ 1 1alive lentiviral positive woman at 32 weeks gestation with snake bite, leg swelling, vaginal bleeding and labour pains. At presentation, there were anemia, tachycardia, hypotension; a gravid uterus with a single fetus in longitudinal lie, cephalic presentation, regular fetal heart rate and cervical dilatation of 3 cm. Preterm labour with antepartum hemorrhage due to venomous snake bite was diagnosed. Multidisciplinary management instituted led to the survival of both mother and baby. Conclusion: In resource constrained setting, disseminated intravascular coagulopathy arising from systemic envenomation due to snake bite in pregnancy could be challenging. Obstetric outcome depends on the degree of envenomation, gestational age at presentation, timing, duration and quality of treatment.

AB - A 29-year-old patient had undergone an elective lower-segment caesarean section (LSCS) five months previously at a district hospital. The operation and the immediate postoperative period were uneventful. After five months she presented back with a fistulous opening. A fistulogram revealed a connection between the uterus and the skin. Fistulous tract excision was planned. Intraoperatively there was communication between the skin and the uterine cavity, with extensive necrosis of the uterine wall. The patient gave her informed consent for excision of the fistulous tract and/or total abdominal hysterectomy. During surgery, it was deemed that there was no scope for excision, so the decision was made for a total abdominal hysterectomy. Histopathological examination confirmed tuberculosis and the patient responded well to anti-tubercular drugs. This case report describes a rare presentation of tubercular uterocutaneous fistula after caesarean section. PMID- 29594006 TI - Postpartum septic pelvic thrombophlebitis after caesarean delivery: a case report. AB - Septic pelvic thrombophlebitis is a rare puerperal complication. It is an important differential diagnosis of postpartum fever and abdominal pain and although the condition is well known its diagnosis can be challenging. We report a case of a 41-year-old woman with fever and right abdominal pain three days after an uncomplicated caesarean delivery. Clinical, laboratory and imaging exams were unremarkable and the patient was treated for endometritis. In the absence of improvement despite an antibiotic adjustment, a clinical diagnosis of septic pelvic thrombophlebitis was made, and the patient presented a good response to anticoagulation in conjunction with broad-spectrum antibiotic therapy. PMID- 29594007 TI - Heterotopic interstitial pregnancy: A case report. AB - Introduction: Before the advent of assisted reproductive technologies, the incidence of heterotopic pregnancy was estimated to be in 1 out of 30,000 pregnancies in the United States. With interstitial pregnancy comprising only 2.4% of ectopic pregnancies, spontaneous heterotopic interstitial pregnancies are exceedingly rare. Case: A 27-year-old pregnant woman (gravida 3 para 1011) with a history of one prior term vaginal delivery and a spontaneous abortion in the first trimester presented to the emergency department with abdominal pain and a positive home pregnancy test. Transvaginal ultrasound confirmed heterotopic pregnancy and she underwent operative management, at which point a ruptured interstitial pregnancy was identified. Conclusion: Heterotopic and interstitial pregnancies are rare and to see them together in a spontaneous pregnancy is virtually unique. The case report describes our management of this rarely seen condition. PMID- 29594008 TI - Pregnancy in a woman with untreated bladder exstrophy: a case report. AB - Objective: To report the management of urinary tract obstruction and infection in a pregnant woman with unrepaired bladder exstrophy. Case Report: A 27-year-old pregnant woman with unrepaired bladder exstrophy was referred to our hospital with a complaint of bilateral flank pain in the second trimester. After two dimensional abdominal ultrasound, magnetic resonance imaging and a urine analysis, she was diagnosed with an upper urinary tract infection due to ureteral obstruction secondary to unrepaired congenital bladder exstrophy and an intrauterine pregnancy. J-tube insertion was performed after locating the ureteral orifices and antibiotics were administered. Symptoms rapidly resolved. She delivered a normal male infant by caesarean section at 34 weeks of gestation. Conclusion: Standard urological management of the ureteral obstruction in pregnancy was successful in this extreme case of unrepaired bladder exstrophy associated with an intrauterine pregnancy. The perinatal outcome was good. PMID- 29594009 TI - Ovarian thrombosis and uterine synechiae after arterial embolization for a late postpartum haemorrhage. AB - Background: We report two unusual separate complications after uterine artery embolization for a late postpartum haemorrhage. This report appeared important to us in view of the apparent absence of any other publications on this topic. Case presentation: We report the case of a 25-year-old woman, gravida 3, para 1, admitted for uterine bleeding 7 days after a spontaneous delivery at term, in our university hospital. A suction curettage and then, after persistent bleeding, uterine artery embolization were necessary. Immediately after the embolization, a bilateral ovarian thrombosis occurred, subsequently followed by amenorrhea, due to uterine synechiae, and depression. Hysteroscopic surgery was performed to remove the adhesions. A complete work-up for thrombophilia showed a heterozygous mutation of the factor V gene R506Q. The pathology examination found subinvolution of the placental bed. One month after treatment of the synechiae (and insertion of a copper IUD for contraception), the woman's menstrual cycle returned to normal. Her clinical examination 19 months later was normal. Conclusions: This case teaches us that one rare complication can hide another! It is important to consider the diagnosis of subinvolution of the placental bed in cases of late PPH and to know the complications associated with vascular artery embolization in order to provide the most rapid and least invasive treatment. PMID- 29594010 TI - Colorectal cancer presenting as tuboovarian abscess in a 40 year old patient with previous tubal occlusion. AB - Background: Although pelvic inflammatory disease can be seen after tubal occlusion, tuboovarian abscess is rare, with only 38 cases reported since 1975 [1]. The differential diagnosis of tuboovarian abscess after tubal occlusion should include non-infectious and non-gynecologic etiology, particularly as women age [2]. Case: A 40 year old multiparous woman with a distant history of tubal occlusion, presented with pelvic pain and suspected right tuboovarian abscess with air on CT scan. A colonic stricture was also seen, warranting further evaluation, which revealed a left tuboovarian abscess which had fistulized from a bowel perforation secondary to colorectal cancer. Conclusion: Tuboovarian abscess is rare after tubal occlusion. These patients should be evaluated specifically for nongynecologic etiology, including colorectal cancer. Radiologic studies can be misleading, and surgical exploration should be strongly considered if a woman with a history of tubal occlusion presents with a presumptive tuboovarian abscess, particularly if the abscess contains air. PMID- 29594011 TI - Ulcus vulvae acutum - A case of genital ulcers in adolescent girl. AB - Ulcus vulvae acutum is a rare clinical condition characterized by the presence of multiple acute painful genital ulcers of non-venereal origin associated with systemic symptoms in young women. The aetiopathogenesis of the disease is not fully understood, although recent reports have associated it with the Epstein Barr virus. Diagnosis is difficult and generally made by exclusion after venereal diseases, and autoimmune, inflammatory, traumatic, and neoplastic causes. We describe a case of adolescent female with an episode of ulcus vulvae acutum associated with infectious mononucleosis. The diagnosis was supported by the clinical symptoms, elevated circulating levels of liver enzymes, positive EBV serology, cervical and inguinal lymphadenomegaly, and hepatosplenomegaly. The patient presented a history of aphthous stomatitis. Negative Pathergy test and the absence of any other related symptoms allowed us to exclude the Behchet syndrome. Lesions healed with no sequelae or recurrences. PMID- 29594012 TI - Prostate cancer screening and active surveillance in the Western world. PMID- 29594013 TI - How to improve duration and quality of life in men? PMID- 29594014 TI - Screening for prostate cancer: are organized screening programs necessary? AB - Already in 1991 when the prostate-specific antigen (PSA) test was proposed as a diagnostic test, screening for prostate cancer (PCa) was considered controversial due to the considerable risk of detecting latent PCa. Randomised controlled trials were initiated to assess the potential of PSA-based screening in reducing disease-specific mortality. Harms and benefit were closely monitored and both were confirmed. A reduction in mortality was seen and at the same time the initial fear of unnecessary testing and over diagnosis became reality. This triggered professional organizations to adapt their guidelines and to focus on shared decision making (SDM) and selective screening for those men considered at high risk. Unfortunately implementation of guidelines into daily clinical practice is bothersome. As a result many men are being (re)tested while not being at risk and the potential benefit being unclear. This raises the question on whether PSA screening should be organized in controlled programs. While the PSA test will remain the mainstay of PCa early detection many other additional tests (biomarkers/imaging) are currently being tested in large population-based initiatives as a first step to organized programs in selective groups of men. PMID- 29594015 TI - Prostate cancer screening: what can we learn from randomised trials? AB - In this article, the principle of randomised trials are first described and then prostate cancer screening trials published to date are evaluated based on these principles. A summary of the randomised prostate cancer screening is provided. The conclusion that can be made from the results of the screening trials, as well as limitations of the evidence and open questions are outlined in the end. PMID- 29594016 TI - Head-to-head comparison of prostate cancer risk calculators predicting biopsy outcome. AB - Background: Multivariable risk calculators (RCs) predicting prostate cancer (PCa) aim to reduce unnecessary workup (e.g., MRI and biopsy) by selectively identifying those men at risk for PCa or clinically significant PCa (csPCa) (Gleason >=7). The lack of an adequate comparison makes choosing between RCs difficult for patients, clinicians and guideline developers. We aim to perform a head-to-head comparison of seven well known RCs predicting biopsy outcome. Methods: Our study comprised 7,119 men from ten independent contemporary cohorts in Europe and Australia, who underwent prostate biopsy between 2007 and 2015. We evaluated the performance of the ERSPC RPCRC, Finne, Chun, ProstataClass, Karakiewicz, Sunnybrook, and PCPT 2.0 (HG) RCs in predicting the presence of any PCa and csPCa. Performance was assessed by discrimination, calibration and net benefit analyses. Results: A total of 3,458 (48%) PCa were detected; 1,784 (25%) men had csPCa. No particular RC stood out predicting any PCa: pooled area under the ROC-curve (AUC) ranged between 0.64 and 0.72. The ERSPC RPCRC had the highest pooled AUC 0.77 (95% CI: 0.73-0.80) when predicting csPCa. Decision curve analysis (DCA) showed limited net benefit in the detection of csPCa, but that can be improved by a simple calibration step. The main limitation is the retrospective design of the study. Conclusions: No particular RC stands out when predicting biopsy outcome on the presence of any PCa. The ERSPC RPCRC is superior in identifying those men at risk for csPCa. Net benefit analyses show that a multivariate approach before further workup is advisable. PMID- 29594017 TI - Multivariable risk-based patient selection for prostate biopsy in a primary health care setting: referral rate and biopsy results from a urology outpatient clinic. AB - Background: According to their guidelines, Dutch general practitioners (GPs) refer men with prostate-specific antigen (PSA) level >=3.0 ng/mL to the urologist for risk-based patient selection for prostate biopsy using the Rotterdam Prostate Cancer Risk Calculator (RPCRC). Use of the RPCRC in primary care could optimize the diagnostic pathway even further by reducing unnecessary referrals. To investigate this, we calculated the risk and assessed the rate of men referred to the urologist with PSA level >=3.0 ng/mL by implementing the RPCRC in a primary health care setting. Methods: In January 2014, an exploratory study was initiated in collaboration with the primary health care facility of the GP laboratory in Rotterdam. GPs were given the possibility to refer men with a suspicion of prostate cancer (PCa) or a screening wish to this primary care facility (STAR SHL) where further assessment was performed by specially trained personnel. Risk based advice on referral to the urologist was given to the GP on the basis of the RPCRC results. If requested, advice on the treatment of lower urinary tract symptoms (LUTS) was provided. All men signed informed consent. Results: Between January 2014 and September 2017, a total of 243 men, median age 64 [interquartile range (IQR), 57-70] years were referred for a consultation at the primary care facility. Of the 108 men with PSA level >=3.0 ng/mL and a referral related to PCa, GPs were advised to refer 58 men to the urologist (54%). Of the men with available follow-up (FU) data [n=187, median FU, 16 (IQR, 9-25) months] 54 men were considered high-risk (i.e., had an elevated risk of PCa as calculated by the RPCRC). Of these men, 51 (94%) were actually referred to secondary care by their GP, and so far 38 men underwent biopsy. PCa was detected in 30 men [47% had Gleason score (GS) >=3+4 PCa], translating to an overall positive predictive value (PPV) of 79%. Within the available FU time, 2 out of 38 (5%) men with PSA level >=3.0 ng/mL which were considered low-risk have been diagnosed with GS 3+3 PCa. Conclusions: Risk-stratification with the RPCRC in a primary health care setting could prevent almost half of referrals of men with PSA level >=3.0 ng/mL to the urologist. In more than three-quarters of men referred for prostate biopsy, the suspicion of PCa was confirmed and almost half of men had clinically significant PCa (GS >=3+4 PCa). These data show a huge potential for multivariable risk-stratification in primary care. PMID- 29594019 TI - Stopping screening, when and how? AB - Screening for prostate cancer (PC) is still controversial despite randomized trials has found that PC mortality is decreased. The major concern is the high rate of over-diagnosis and subsequent harms that may follow in many men who never would have had any symptoms during life-time if not screened. The high rate of over-diagnosis is driven by the large reservoir of small non-significant cancers that increases with age and found in more than half of men over 70 years, the low specificity of prostate specific antigen (PSA) but also by current "blind" biopsy technique that risk accidentally to hit these small non-significant cancers. The risk of over-diagnosis is increasing with age and the trade-off by screening men in high age is probably higher. At what age harms exceeds benefits is not established but modelling studies has demonstrated that after 65-70 years the quality adjusted life-years (QALYs) gained are decreasing but still on the positive side if screening is continued up to 75 years. A dilemma is that most PC deaths occur in men after the age 80 and the effect of screening seems not to last as long as was thought, already 10 years after termination of screening PC mortality has caught up in the screening arm to a level similar to that in the control group. In the European Randomised Study of Screening for Prostate Cancer (ERSPC) screening was terminated between 71 and 75 years and the first effect of screening on mortality was discernible after 7 years and has been relatively stable around 20% since 9 years after study start. It seems questionable from any standpoint to invite men for screening with an expected life length below 10 years, which is the expected life-length of an averaged 78-year-old man in 2018. However, the balance between harms and benefits specifically in the age 70-80 need more attention as also costs need. Permanent side-effects from (unnecessary) treatments and their impact on quality of life must be evaluated better and related to age and individual variations. In future better screening methods with more specific markers and introduction of imaging will hopefully decrease the present large risk of over-diagnosis in elderly men and thereby expand efficient screening to men in the age group >70 who actually is the high risk group of dying from PC. PMID- 29594018 TI - Prostate cancer screening-when to start and how to screen? AB - Prostate-specific antigen (PSA) screening reduces prostate cancer (PCa) mortality; however such screening may lead to harm in terms of overdiagnosis and overtreatment. Therefore, upfront shared decision making involving a discussion about pros and cons between a physician and a patient is crucial. Total PSA remains the most commonly used screening tool and is a strong predictor of future life-threatening PCa. Currently there is no strong consensus on the age at which to start PSA screening. Most guidelines recommend PSA screening to start no later than at age 55 and involve well-informed men in good health and a life expectancy of at least 10-15 years. Some suggest to start screening in early midlife for men with familial predisposition and men of African-American descent. Others suggest starting conversations at age 45 for all men. Re-screening intervals can be risk stratified as guided by the man's age, general health and PSA-value; longer intervals for those at lower risk and shorter intervals for those at higher risk. Overdiagnosis and unnecessary biopsies can be reduced using reflex tests. Magnetic resonance imaging in the pre-diagnostic setting holds promise in pilot studies and large-scale prospective studies are ongoing. PMID- 29594020 TI - What is an acceptable false negative rate in the detection of prostate cancer? AB - Background: In prostate cancer (PCa) screening men and their physicians aim to rule out the presence of potentially life threatening PCa. To date, prostate specific antigen (PSA) testing and systematic prostate biopsy (Bx)-in case of an elevated PSA-are still the main modes of PCa detection. Often uncertainty remains when a PSA-test is <3.0 ng/mL or a Bx shows a benign result, leading to the continuous repeating of procedures. Here we assess the potential consequences of false negatives by studying follow-up data of a purely PSA-based approach with applying sextant Bx, an approach considered to have a high risk of missing PCa diagnosis. Methods: Our study population consisted of 19,970 men from the ERSPC project section Rotterdam, initially screened in 1993-1999. We assessed clinically significant Gleason >=3+4 PCa (csPCa) diagnosis within the 4-year screening interval and subsequent screening round 4 years later in men having a PSA <3.0 ng/mL at initial screening (no Bx) and men with Bx (PSA >3.0 ng/mL), but no PCa detected at that time. In addition, we addressed PCa mortality and PCa diagnosis for men with a negative PSA test and negative Bx, who were retested every 4 years covering a 15-year follow-up. Results: A total of 14,935 men had PSA <3.0 ng/mL in the initial screening round, of whom 75 (0.5%) were diagnosed with csPCa at a subsequent screening examination and 2 (<0.1%) in the 4-year screening interval. For 2,260 men with a previously negative Bx at first screening, the figures were 17 (0.8%) and 2 (0.1%) respectively. Indolent PCa (Gleason <=3+3) was diagnosed in 312 (2%) men with PSA <3.0 ng/mL initially and 115 (5%) men with initial negative Bx. After a 15-year follow-up, 45 (0.3%) PCa deaths occurred in men with initially low PSA, and 29 men (0.2%) had metastasis. For men with negative Bx, 11 (0.5%) PCa deaths occurred and 4 (0.2%) experienced metastasis. Conclusions: The false negative rates for men with PSA <3.0 ng/mL and negative sextant Bx are extremely low but not negligible. Proper risk stratification before deciding to biopsy is expected to hardly miss any clinical significant PCa diagnosis. This is especially relevant with the increased use of the relatively expensive multi-parametric magnetic resonance imaging (mpMRI) guided targeted Bx procedures. PMID- 29594021 TI - Men with a susceptibility to prostate cancer and the role of genetic based screening. AB - Prostate cancer is the second most common malignancy affecting men worldwide, and the commonest affecting men of African descent. Significant diagnostic and therapeutic advances have been made in the past decade. Improvements in the accuracy of prostate cancer diagnosis include the uptake of multi-parametric MRI and a shift towards targeted biopsy. We also now have more life-prolonging systemic and hormonal therapies for men with advanced disease at our disposal than ever before. However, the development of robust screening tools and targeted screening programs has not followed at the same pace. Evidence to support population-based screening remains unclear, with the use of PSA as a screening test limiting our ability to discriminate between clinically significant and insignificant disease. Prostate cancer has a large heritable component. Given that most men without risk factors have a low lifetime risk of developing lethal prostate cancer, much work is being done to further our knowledge of how we can best screen men in higher risk categories, such as those with a family history (FH) of the disease or those of African ancestry. These men have been reported to carry upwards of a two-fold increased risk of developing the disease at an earlier age, with evidence suggesting poorer survival outcomes. In men with a FH of prostate cancer, this is felt to be due to rare, high-penetrance mutations and the presence of multiple, common low penetrance alleles, with men carrying specific germline mutations in the BRCA and other DNA repair genes at particularly high risk. To date, large scale genome-wide association studies (GWAS) have led to the discovery of approximately 170 single nucleotide polymorphisms (SNPs) associated with prostate cancer risk, allowing over 30% of prostate cancer risk to be explained. Genomic tests, utilising somatic (prostate biopsy) tissue can also predict the risk of unfavourable pathology, biochemical recurrence and the likelihood of metastatic disease using gene expression. Targeted screening studies are currently under way in men with DNA repair mutations, men with a FH and those of Afro-Caribbean ethnicity which will greater inform our understanding of disease incidence and behaviour in these men, treatment outcomes and developing the most appropriate screening regime for such men. Incorporating a patient's genetic mutation status into risk algorithms allows us an opportunity to develop targeted screening programs for men in whom early cancer detection and treatment will positively influence survival, and in the process offer male family members of affected men the chance to be counselled and screened accordingly. PMID- 29594022 TI - MRI in early prostate cancer detection: how to manage indeterminate or equivocal PI-RADS 3 lesions? AB - This review focuses on indeterminate lesions on prostate magnetic resonance imaging (MRI), assigned as PI-RADS category 3. The prevalence of PI-RADS 3 index lesion in the diagnostic work-up is significant, varying between one in three (32%) to one in five (22%) men, depending on patient cohort of first biopsies, previously negative biopsies, and active surveillance biopsies. A management strategy must be developed for this group of men with an indeterminate suspicion of having clinically significant prostate cancer (csPCa). Currently available data show that the actual prevalence of csPCa after targeted biopsy in PI-RADS 3 lesions vary between patients groups from one in five (21%) to one in six (16%), depending on previous biopsy status. Although this prevalence is lower in comparison to PI-RADS 4 and PI-RADS 5 lesions, still a considerable proportion of men harbor significant disease. Men with such a PI-RADS 3 lesion should therefore be adequately managed. In general, the clinical approach of using a threshold of PI-RADS >=4 instead of PI-RADS >=3 to select MRI for targeted biopsies is not supported by data from our explorative literature search using current definitions of csPCa. A possible adaptation to the threshold of PI-RADS >=4 in combination with other clinical markers could be considered within an active surveillance protocol, where the balance between the individual risk of missing csPCa and the constant process of repeating prostate biopsies is crucial. In the future, improvements in MR imaging and interpretation, combined with molecular biomarkers and multivariate risk models will all be employed in prostate cancer detection and monitoring. These combinations will aid decision-making in challenging circumstances, such as unclear and diagnostic equivocal results for csPCa at early detection. PMID- 29594023 TI - Active surveillance for prostate cancer: a systematic review of contemporary worldwide practices. AB - In the last decade, active surveillance (AS) has emerged as an acceptable choice for low-risk prostate cancer (PC), however there is discordance amongst large AS cohort studies with respect to entry and monitoring protocols. We systematically reviewed worldwide AS practices in studies reporting >=5 years follow-up. We searched PubMed and Medline 2000-now and identified 13 AS cohorts. Three key areas were identified: (I) patient selection; (II) monitoring protocols; (III) triggers for intervention-(I) all studies defined clinically localised PC diagnosis as T2b disease or less and most agreed on prostate-specific antigen (PSA) threshold (<10 ug/L) and Gleason score threshold (3+3). Inconsistency was most notable regarding pathologic factors (e.g., number of positive cores); (II) all agreed on PSA surveillance as crucial for monitoring, and most agreed that confirmatory biopsy was required within 12 months of initiation. No consensus was reached on optimal timing of digital rectal examination (DRE), general health assessment or re-biopsy strategies thereafter; (III) there was no universal agreement for intervention triggers, although Gleason score, number or percentage of positive cancer cores, maximum cancer length (MCL) and PSA doubling time were used by several studies. Some also used imaging or re-biopsy. Despite consistent high progression-free/cancer-free survival and conversion-to-treatment rates, heterogeneity exists amongst these large AS cohorts. Combining existing evidence and gathering more long-term evidence [e.g., the Movember's Global AS database or additional information on use of magnetic resonance imaging (MRI)] is needed to derive a broadly supported guideline to reduce variation in clinical practice.

AB - Background: Active surveillance (AS) for low-risk prostate cancer (PCa) appears to provide excellent long-term PCa-specific and overall survival. The choice for AS as initial treatment is mainly based on avoiding side effects from invasive treatment; but AS entails regular check-ups and the possibility of still having to switch or deciding to switch to invasive treatment. Here, we assessed the long term follow-up data from AS in real life clinical practices. Methods: Data from the first 500 men, enrolled in PRIAS before July 2008 by 30 centers across 8 countries, were analyzed to provide long-term follow-up results. Men were advised to be regularly examined with prostate-specific antigen (PSA) tests, digital rectal examinations, and prostate biopsies. Men were advised to switch to invasive treatment if they had disease reclassification [Gleason score (GS) >=3+4 on biopsy, more than two positive biopsy cores, a stage higher than cT2] or a PSA doubling time of 0-3 years. We assessed time on AS, outcomes and reasons for discontinuing AS, and rates of potential unnecessary biopsies and treatments. Results: The median follow-up time was 6.5 years. During this period, 325 (65%) men discontinued after a median of 2.3 years and 121 (24%) men had no recent (>1 year) data-update after a median of 7.3 years. The remaining 54 (11%) men were confirmed to be still on AS. Most men discontinued based on protocol advice; 38% had other reasons. During follow-up, 838 biopsy sessions were performed of which 79% to 90% did not lead to reclassification, depending on the criteria. Of the 325 discontinued men, 112 subsequently underwent radical prostatectomy (RP), 126 underwent radiotherapy, 57 switched to watchful waiting (WW) or died, and 30 had another or unknown treatment. RP results were available of 99 men: 34% to 68%, depending on definition, had favorable outcomes; 50% of unfavorable the outcomes occurred in the first 2 years. Of the 30 (6%) men who died, 1 man died due to PCa. Conclusions: These data, reflecting real life clinical practice, show that more than half of men switched to invasive treatment within 2.3 years, indicating limitations to the extent in which AS is able to reduce the adverse effects of overdiagnosis. Therefore, despite guidelines stating that PCa diagnosis must be uncoupled from treatment, it remains important to avoid overdiagnosing PCa as much as possible. PMID- 29594025 TI - Active surveillance: a review of risk-based, dynamic monitoring. AB - Active surveillance (AS) is an important treatment modality aiming to reduce the overtreatment of patients with prostate cancer (PCa) who have a low risk of disease reclassification. After enrolling in AS patients are actively monitored using different diagnostic tests (e.g., prostate specific-antigen, digital rectal exams (DREs), medical imaging, and prostate biopsies). Biopsy is the most burdensome test. We aimed to review schedules for monitoring men on AS. We compare fixed versus risk based dynamic monitoring, where biopsies are scheduled during follow-up based on dynamic risk predictions. Several prediction models and scheduling techniques have been published. All proposed risk prediction models need further external validation. We conclude that risk based, dynamic monitoring is a promising new strategy to further reduce overtreatment in PCa patients. PMID- 29594026 TI - Magnetic resonance imaging in active surveillance-a modern approach. AB - In recent years, active surveillance has been increasingly adopted as a conservative management approach to low and sometimes intermediate risk prostate cancer, to avoid or delay treatment until there is evidence of higher risk disease. A number of studies have investigated the role of multiparametric magnetic resonance imaging (mpMRI) in this setting. MpMRI refers to the use of multiple MRI sequences (T2-weighted anatomical and functional imaging which can include diffusion-weighted imaging, dynamic contrast enhanced imaging, spectroscopy). Each of the parameters investigates different aspects of the prostate gland (anatomy, cellularity, vascularity, etc.). In addition to a qualitative assessment, the radiologist can also extrapolate quantitative imaging biomarkers from these sequences, for example the apparent diffusion coefficient from diffusion-weighted imaging. There are many different types of articles (e.g., reviews, commentaries, consensus meetings, etc.) that address the use of mpMRI in men on active surveillance for prostate cancer. In this paper, we compare original articles that investigate the role of the different mpMRI sequences in men on active surveillance for prostate cancer, in order to discuss the relative utility of the different sequences, and combinations of sequences. We searched MEDLINE/PubMed for manuscripts published from inception to 1st December 2017. The search terms used were (prostate cancer or prostate adenocarcinoma or prostatic carcinoma or prostate carcinoma or prostatic adenocarcinoma) and (MRI or NMR or magnetic resonance imaging or mpMRI or multiparametric MRI) and active surveillance. Overall, 425 publications were found. All abstracts were reviewed to identify papers with original data. Twenty five papers were analysed and summarised. Some papers based their analysis only on one mpMRI sequence, while others assessed two or more. The evidence from this review suggests that qualitative assessments and quantitative data from different mpMRI sequences hold promise in the management of men on active surveillance for prostate cancer. Both qualitative and quantitative approaches should be considered when assessing mpMRI of the prostate. There is a need for robust studies assessing the relative utility of different combinations of sequences in a systematic manner to determine the most efficient use of mpMRI in men on active surveillance. PMID- 29594027 TI - Reduction of MRI-targeted biopsies in men with low-risk prostate cancer on active surveillance by stratifying to PI-RADS and PSA-density, with different thresholds for significant disease. AB - Background: The fear of undergrading prostate cancer (PCa) in men on active surveillance (AS) have led to strict criteria for monitoring, which have resulted in good long-term cancer-specific survival, proving the safety of this approach. Reducing undergrading, MRI-targeted biopsies are increasingly used in men with low-risk disease despite their undefined role yet. The objective of this study is to investigate the rate of upgrading using MRI-targeted biopsies in men with low risk disease on AS, stratified on the basis of PI-RADS and PSA-density, with the aim to reduce potential unnecessary repeat biopsy procedures. Methods: A total of 331 men were prospectively enrolled following the MRI-PRIAS protocol. MR imaging was according to Prostate Imaging Reporting and Data System (PI-RADSv2) guidelines. Suspicious MRI lesions (PI-RADS 3-5) were additionally targeted by MRI-TRUS fusion biopsies. Outcome measure was upgrading to Gleason score (GS) >=3+4 with MRI-targeted biopsies, stratified for PI-RADS and PSA-density. Results: In total, 25% (82/331) of men on AS showed upgrading from GS 3+3. Only 3% (11/331) was upgraded to GS >=8. In 60% (198/331) a suspicious MRI lesion was identified, but in only 41% (82/198) of men upgrading was confirmed. PI-RADS 3, 4 and 5 categorized index lesions, showed upgrading in 30%, 34% and 66% of men, respectively. Stratification to PI-RADS 4-5, instead of PI-RADS 3-5, would have missed a small number of high volume Gleason 4 PCa in PI-RADS 3 category. However, further stratification into PI-RADS 3 lesions and PSA-density <0.15 ng/mL2 could result in a safe targeted biopsy reduction of 36% in this category, without missing any upgrades. Conclusions: Stratification with the combination of PI-RADS and PSA-density may reduce unnecessary additional MRI biopsy testing. Overall, the high rate of detected upgrading in men on AS may result in an unintended tightening of continuing in AS. Since patients, included under current AS criteria showed extremely favorable outcome, there might be no need to further restrict continuing on AS with MRI and targeted biopsies. PMID- 29594028 TI - On cribriform prostate cancer. AB - The management of newly diagnosed prostate cancer is challenging because of its heterogeneity in histology, genetics and clinical outcome. The clinical outcome of patients with Gleason score 7 prostate cancer varies greatly. Improving risk assessment in this group is of particular interest, as Gleason score 7 prostate cancer on biopsy is an important clinical threshold for active treatment. Architecturally, four Gleason grade 4 growth patterns are recognized: ill-formed, fused, glomeruloid and cribriform. The aim of this review is to describe the role of cribriform growth in prostate cancer with respect to diagnosis, prognosis and molecular pathology. Secondly, we will discuss clinical applications for cribriform prostate cancer and give recommendations for future research. PMID- 29594029 TI - Biomarkers in active surveillance. AB - The use of active surveillance (AS) is increasing for favorable-risk prostate cancer. However, there remain challenges in patient selection for AS, due to the limitations of current clinical staging. In addition, monitoring protocols relying on serial biopsies is invasive and presents risks such as infection. For these reasons, there is substantial interest in identifying markers that can be used to improve AS selection and monitoring. In this article, we review the evidence on serum, urine and tissue markers in AS. PMID- 29594030 TI - Quality of life in active surveillance and the associations with decision-making a literature review. AB - Several studies have been conducted on the quality of life (QoL) in men with low risk prostate cancer (PCa) who choose active surveillance (AS). While recent reviews have shown a lack of consistency among the available QoL-studies, a few key points have been identified, including decision-making (DM)-related issues and their potential effect on QoL. The importance of this theme has also been recently highlighted by the international task force of the European School of Oncology. However, to our knowledge, there are no studies that have specifically marshalled scientific knowledge on the association between DM and QoL among men with low-risk PCa undergoing AS. We performed a literature review to fill this gap, taking a systematic approach to retrieving and selecting articles that included both DM and QoL measures. Among the 272 articles retrieved, we selected nine observational, quantitative articles with both DM and QoL measures. The most considered DM aspects within these studies were decisional conflict and preference for the patient's role in the DM process, as well as health-related QoL aspects. The studies included 42 assessments of the relationship between an empirical measure of DM and an empirical measure of QoL. Among these assessments, 23 (55%) were both positive and significant. They mostly concerned the relationship between patient-related (decisional self-efficacy, decisional control and knowledge) and external (presence of social support, collaborative role within the DM process, and influence of different physicians) DM aspects, as well as the QoL after choice. The findings of these studies revealed key challenges to research and clinical practice related to DM and QoL in AS. These include adopting a person-centred perspective where clinicians, caregivers and their interactions are also included in evaluations and where the psychosocial existential experience of individuals within the DM and AS journey is considered. Much more attention needs to be paid to the DM process after diagnosis, as well as to all the other moments where patients may have to or want to review their decision. Healthcare professionals play a key role in enabling men to make informed decisions and to take care of their health and well-being during AS. There is still work that needs to be done in training healthcare professionals from different disciplines to work together in a model of shared DM and AS tailored to the needs of low-risk PCa patients and their family members. PMID- 29594031 TI - eHealth and mHealth in prostate cancer detection and active surveillance. AB - eHealth and mobile health (mHealth) offer patients, healthcare providers, researchers, and policy makers new potential to improve wellness, practice prevention and reduce suffering from diseases. While the eHealth market is growing to an expected US $26 billion, its potential in the field of Urology is still underused. Research has shown that currently only 176 apps (of the 300,000 medical apps available) were found in the Apple App Store and Google Play Store, of which 20 were prostate cancer related. Three good examples of eHealth/mHealth applications are the Rotterdam Prostate Cancer Risk Calculator (RPCRC) website and app, the Prostate cancer Research International Active Surveillance (PRIAS) website and the Follow MyPSA app for men on active surveillance for prostate cancer: they are tools with a clear vision that offer true added value in daily clinical practice and which positively influence healthcare beyond borders. To increase the uptake of eHealth applications in the coming years, it is important to involve professionals in their design and development, and to guarantee the safety and privacy of its users and their data. PMID- 29594032 TI - Being on active surveillance: the patient perspective. AB - Prostate cancer (PCa) patients selected for active surveillance (AS) have received information on prostate cancer PCa, treatment, knew their serum prostate specific antigen (PSA), a digital rectal examination (DRE) done and could rely on their set of biopsies to be labelled as low grade, low volume disease (by adding a radiographic/ultrasonic measurement). They usually react euphoric to the selection hoping to escape invasive curative treatment and its side-effects. Unfortunately, this positive feeling waivers in front of uncertainty in the follow-up including biopsies. Improvements on prognostics are needed. The patients need reassuring information and confidence building to keep his choice to AS based on evidence and confidence. PMID- 29594033 TI - The future of prostate cancer research: bringing data together, looking back and forward. AB - The use of digital data in large data sets will be of pivotal importance to unravel the biological basis of prostate cancer, and to improve on prevention and treatment. For the screening of asymptomatic tumors, their identification, and their treatment with better and targeted therapies, the integration of information from imaging, genomics, and biomarkers is needed. To bring these (un)structured data together, block chain technology is required, while knowledgeable analysts should be available. Therefore, it is of utmost importance to 'team up' and provide a common strategy for innovation. Its implementation needs the involvement of all stakeholders (patients, industries, professionals, scientists, governments). This article provides thoughts on how initial steps in urology have been taken, and how to proceed. PMID- 29594034 TI - Current perspectives on the role of the pharmacist in heart failure management. AB - Pharmacists play an important role within a multidisciplinary health care team in the care of patients with heart failure (HF). It has been evaluated and documented that pharmacists providing medication reconciliation especially during transition of care, educating patients on their medications, and providing collaborative medication management lead to positive changes in the patient outcomes, including but not limited to decreasing in hospitalizations and read missions. It is foreseeable that pharmacist roles will continue to expand as new treatment and innovative care are developed for HF patients. I reviewed published role of pharmacists in the care of HF patients. MEDLINE and Current Content database (both from 1966 - December 31, 2017) were utilized to identify peer reviewed clinical trials, descriptive studies, and review articles published in English using the following search terms: pharmacists, clinical pharmacy, HF, and cardiomyopathy. Citations from available articles were also reviewed for additional references. Preliminary search revealed 31 studies and 55 reviews. They were further reviewed by title and abstract as well as full text to remove irrelevant articles. At the end, 24 of these clinical trials and systematic reviews are described in the following text and Table 1 summarizes 16 pertinent clinical trials. Some roles that are currently being explored include medication management in patients with mechanical circulatory support for end-stage HF, where pharmacokinetics and pharmacodynamics of medications can change, medication management in ambulatory intravenous diuretic clinics, and comprehensive medication management in patients' home settings. Pharmacists should continue to explore and prospectively evaluate their role in the care of this patient population, including documenting their interventions, and impact to economic and patient outcomes. PMID- 29594036 TI - Dosimetric Impact of a Tumor Treating Fields Device for Glioblastoma Patients Undergoing Simultaneous Radiation Therapy. AB - Purpose: A recent randomized phase III clinical trial in patients with glioblastoma demonstrated the efficacy of tumor treating fields (TTFields), in which alternating electric fields are applied via transducer arrays to a patient's scalp. This treatment, when added to standard of care therapy, was shown to increase overall survival from 16 to 20.9 months. These results have generated significant interest in incorporating the use of TTFields during postoperative concurrent chemoradiation. However, the dosimetric impact of high density electrodes on the scalp, within the radiation field, is unknown. Methods: The dosimetric impact of TTFields electrodes in the radiation field was quantified in two ways: (1) dose calculated in a treatment planning system and (2) physical measurements of surface and deep doses. In the dose calculation comparison, a volumetric-modulated-arc-therapy (VMAT) radiation plan was developed on a CT scan without electrodes and then recalculated with electrodes. For physical measurements, the surface dose underneath TTFields electrodes were measured using a parallel plate ionization chamber and compared to measurements without electrodes for various incident beam angles and for 12 VMAT arc deliveries. Deep dose measurements were conducted for five VMAT plans using Scandidos Delta4 diode array: measured doses on two orthogonal diode arrays were compared. Results: In the treatment planning system, the presence of the TTFields device caused mean reduction of PTV dose of 0.5-1%, and a mean increase in scalp dose of 0.5-1 Gy. Physical measurement showed increases of surface dose directly underneath by 30-110% for open fields with varying beam angles and by 70-160% for VMAT deliveries. Deep dose measurement by diode array showed dose decrease of 1 2% in most areas shadowed by the electrodes (max decrease 2.54%). Conclusion: The skin dose in patients being treating with cranial irradiation for glioblastoma may increase substantially (130-260%) with the addition of concurrent TTFields electrodes on the scalp. However, the impact of dose attenuation by the electrodes on deep dose during VMAT treatment is of much smaller, but measureable, magnitude (1-2%). Clinical trials exploring concurrent TTFields with cranial irradiation for glioblastoma may utilize scalp-sparing techniques to mitigate any potential increase in skin toxicity. PMID- 29594035 TI - Targeting Macrophages in Cancer: From Bench to Bedside. AB - Macrophages are a major component of the tumor microenvironment and orchestrate various aspects of immunity. Within tumors, macrophages can reversibly alter their endotype in response to environmental cues, including hypoxia and stimuli derived from other immune cells, as well as the extracellular matrix. Depending on their activation status, macrophages can exert dual influences on tumorigenesis by either antagonizing the cytotoxic activity immune cells or by enhancing antitumor responses. In most solid cancers, increased infiltration with tumor-associated macrophages (TAMs) has long been associated with poor patient prognosis, highlighting their value as potential diagnostic and prognostic biomarkers in cancer. A number of macrophage-centered approaches to anticancer therapy have been investigated, and include strategies to block their tumor promoting activities or exploit their antitumor effector functions. Integrating therapeutic strategies to target TAMs to complement conventional therapies has yielded promising results in preclinical trials and warrants further investigation to determine its translational benefit in human cancer patients. In this review, we discuss the molecular mechanisms underlying the pro-tumorigenic programming of macrophages and provide a comprehensive update of macrophage targeted therapies for the treatment of solid cancers. PMID- 29594037 TI - Defining the Role of Solid Stress and Matrix Stiffness in Cancer Cell Proliferation and Metastasis. AB - Solid tumors are characterized by an abnormal stroma that contributes to the development of biomechanical abnormalities in the tumor microenvironment. In particular, these abnormalities include an increase in matrix stiffness and an accumulation of solid stress in the tumor interior. So far, it is not clearly defined whether matrix stiffness and solid stress are strongly related to each other or they have distinct roles in tumor progression. Moreover, while the effects of stiffness on tumor progression are extensively studied compared to the contribution of solid stress, it is important to ascertain the biological outcomes of both abnormalities in tumorigenesis and metastasis. In this review, we discuss how each of these parameters is evolved during tumor growth and how these parameters are influenced by each other. We further review the effects of matrix stiffness and solid stress on the proliferative and metastatic potential of cancer and stromal cells and summarize the in vitro experimental setups that have been designed to study the individual contribution of these parameters. PMID- 29594038 TI - Priming the Abscopal Effect Using Multifunctional Smart Radiotherapy Biomaterials Loaded with Immunoadjuvants. AB - In this study, we investigate the use of multifunctional smart radiotherapy biomaterials (SRBs) loaded with immunoadjuvants for boosting the abscopal effect of local radiotherapy (RT). SRBs were designed similar to currently used inert RT biomaterials, incorporating a biodegradable polymer with reservoir for loading payloads of the immunoadjuvant anti-CD40 monoclonal antibody. Lung (LLC1) tumors were generated both on the right and left flank of each mouse, with the left tumor representing metastasis. The mice were randomized and divided into eight cohorts with four cohorts receiving image-guided RT (IGRT) at 5 Gy and another similar four cohorts at 0 Gy. IGRT and Computed Tomography (CT) imaging were performed using a small animal radiation research platform (SARRP). Tumor volume measurements for both flank tumors and animal survival was assessed over 25 weeks. Tumor volume measurements showed significantly enhanced inhibition in growth for the right flank tumors of mice in the cohort treated with SRBs loaded with CD40 mAbs and IGRT. Results also suggest that the use of polymeric SRBs with CD40 mAbs without RT could generate an immune response, consistent with previous studies showing such response when using anti-CD40. Overall, 60% of mice treated with SRBs showed complete tumor regression during the observation period, compared to 10% for cohorts administered with anti-CD40 mAbs, but no SRB. Complete tumor regression was not observed in any other cohorts. The findings justify more studies varying RT doses and quantifying the immune-cell populations involved when using SRBs. Such SRBs could be developed to replace currently used RT biomaterials, allowing not only for geometric accuracy during RT, but also for extending RT to the treatment of metastatic lesions. PMID- 29594039 TI - Genetic Evidence for Early Peritoneal Spreading in Pelvic High-Grade Serous Cancer. AB - Background: Most pelvic high-grade serous (HGS) carcinomas have been proposed to arise from tubal primaries that progress rapidly to advanced disease. However, the temporal sequence of ovarian and peritoneal metastases is not well characterized. Methods: To establish the sequence of metastases, phylogenetic relationships among the ovarian and peritoneal carcinomas were determined from single-nucleotide variations (SNVs) in nine tumor regions from each patient with pelvic HGS carcinomas. Somatic SNVs from each tumor sample were used to reconstruct phylogenies of samples from each patient. Variant allele frequencies were used to reconstruct subclone phylogenies in each tumor sample. Results: We show that pelvic HGS carcinomas are highly heterogeneous, only sharing less than 4% of somatic SNVs among all nine carcinoma implants in one patient. TP53 mutations are found in all nine carcinoma implants in each patient. The phylogenetic analyses reveal that peritoneal metastases arose from early branching events that preceded branching events for ovarian carcinomas in some patients. Finally, subclone phylogenies indicate the presence of multiple subclones at each tumor implant and early tumor clones in peritoneal implants. Conclusion: The genetic evidence that peritoneal implants arose before or concurrently with ovarian implants is consistent with the emerging concept of the extra-ovarian origin of pelvic HGS cancer. Our results challenge the concept of stepwise spatial progression from the fallopian primary to ovarian carcinomas to peritoneal dissemination and suggest an alternative progression model where peritoneal spreading of early clones occurs before or in parallel with ovarian metastases. PMID- 29594040 TI - Cancer Cell Mechanics: Adhesion G Protein-coupled Receptors in Action? AB - In mammals, numerous organ systems are equipped with adhesion G protein-coupled receptors (aGPCRs) to shape cellular processes including migration, adhesion, polarity and guidance. All of these cell biological aspects are closely associated with tumor cell biology. Consistently, aberrant expression or malfunction of aGPCRs has been associated with dysplasia and tumorigenesis. Mounting evidence indicates that cancer cells comprise viscoelastic properties that are different from that of their non-tumorigenic counterparts, a feature that is believed to contribute to the increased motility and invasiveness of metastatic cancer cells. This is particularly interesting in light of the recent identification of the mechanosensitive facility of aGPCRs. aGPCRs are signified by large extracellular domains (ECDs) with adhesive properties, which promote the engagement with insoluble ligands. This configuration may enable reliable force transmission to the ECDs and may constitute a molecular switch, vital for mechano dependent aGPCR signaling. The investigation of aGPCR function in mechanosensation is still in its infancy and has been largely restricted to physiological contexts. It remains to be elucidated if and how aGPCR function affects the mechanoregulation of tumor cells, how this may shape the mechanical signature and ultimately determines the pathological features of a cancer cell. This article aims to view known aGPCR functions from a biomechanical perspective and to delineate how this might impinge on the mechanobiology of cancer cells. PMID- 29594042 TI - Biotherapies in Solid Tumors: Are Negative Results Still of Low Priority for Publication? AB - In 2005, we performed the largest survey on clinical trials of biotherapies for all solid tumors and found indirect evidence of a publication bias: editors of medical journals were more prone to publish positive results independently from the quality of the studies. We collected data from 2003 to 2015 in 487 studies, and the publication bias previously described was not found in the years between 2010 and 2015: this could be related to changes and/or innovations in the guidelines and editorial policies of oncology journals occurred over the last years. PMID- 29594041 TI - DNX-2401, an Oncolytic Virus, for the Treatment of Newly Diagnosed Diffuse Intrinsic Pontine Gliomas: A Case Report. AB - Diffuse intrinsic pontine gliomas (DIPGs) are aggressive glial brain tumors that primarily affect children, for which there is no curative treatment. Median overall survival is only one year. Currently, the scientific focus is on expanding the knowledge base of the molecular biology of DIPG, and identifying effective therapies. Oncolytic adenovirus DNX-2401 is a replication-competent, genetically modified virus capable of infecting and killing glioma cells, and stimulating an anti-tumor immune response. Clinical trials evaluating intratumoral DNX-2401 in adults with recurrent glioblastoma have demonstrated that the virus has a favorable safety profile and can prolong survival. Subsequently, these results have encouraged the transition of this biologically active therapy from adults into the pediatric population. To this aim, we have designed a clinical Phase I trial for newly diagnosed pediatric DIPG to investigate the feasibility, safety, and preliminary efficacy of delivering DNX 2401 into tumors within the pons following biopsy. This case report presents a pediatric patient enrolled in this ongoing Phase I trial for children and adolescents with newly diagnosed DIPG. The case involves an 8-year-old female patient with radiologically diagnosed DIPG who underwent stereotactic tumor biopsy immediately followed by intratumoral DNX-2401 in the same biopsy track. Because there were no safety concerns or new neurological deficits, the patient was discharged 3 days after the procedures. To our knowledge, this is the first report of intratumoral DNX-2401 for a patient with DIPG in a clinical trial. We plan to demonstrate that intratumoral delivery of an oncolytic virus following tumor biopsy for pediatric patients with DIPG is a novel and feasible approach and that DNX-2401 represents an innovative treatment for the disease. PMID- 29594043 TI - In Vitro Model-Systems to Understand the Biology and Clinical Significance of Circulating Tumor Cell Clusters. AB - The isolation of clusters of circulating tumor cells (CTCs) from cancer patients has recently challenged the accepted view that the initiation of secondary tumors during metastasis involves the dissemination of individual cancer cells. As such clusters appear to be more aggressive than single tumor cells, CTC clusters are now considered a main player in the metastatic process, and many studies are exploring their diagnostic, prognostic, and clinical significance. However, several technical challenges limit advances in this area. Here, we suggest the use of established cancer cell lines that grow as cell clusters in suspension as a complementary approach that can help in understanding the biology of CTC clusters and their clinical significance. We argue that the many similarities between these "surrogate" clusters and the CTC clusters isolated from patients (e.g., in terms of size, morphology, heterogeneous expression of epithelial and mesenchymal markers, and type of cell-cell junctions) make these cell lines ideal systems for the development of strategies aimed at preventing or slowing down the metastatic process by targeting CTC clusters. PMID- 29594044 TI - A Phase Ib/II Study of Ganetespib With Doxorubicin in Advanced Solid Tumors Including Relapsed-Refractory Small Cell Lung Cancer. AB - Introduction: Small cell lung cancer (SCLC) accounts for 15% of all lung cancers and is characterized by high response rates to cytotoxic chemotherapy and equally high rates of relapse. Many resistance mechanisms have been proposed including resistance to doxorubicin via induction of a heat shock response. Ganetespib is a novel and potent non-geldanamycin heat shock protein 90 (Hsp90) inhibitor. In preclinical studies, synergy between ganetespib and doxorubicin was shown. We conducted a phase Ib/II study of the safety, tolerability, and preliminary efficacy of the combination of ganetespib and doxorubicin. Methods: Patients eligible for the phase Ib portion had advanced tumors that would be appropriate for doxorubicin therapy and those in the phase II portion had relapsed or refractory SCLC. All patients had an ECOG performance status, 0-1 and adequate organ function, including a cardiac ejection fraction >=50%. Patients who received a lifetime cumulative doxorubicin dose of >150 mg/m2 or who had symptomatic brain metastases were excluded. Patients received ganetespib on Days 1 and 8 and doxorubicin 50 mg/m2 on day 1 in 21-day cycles. Results: Eleven patients were enrolled including nine in the phase Ib dose escalation and two in the phase II expansion. The study was terminated by the sponsor. The dose recommended for future study is ganetespib 150 mg/m2 in combination with doxorubicin at a dose of 50 mg/m2. The most common adverse events of the combination were grade 1/2 diarrhea, nausea, fatigue, and transaminitis. No dose limiting toxicities were observed. Response rate was 25% and median duration of response was 137 days. Conclusion: Ganetespib plus doxorubicin was a well tolerated combination and there remains potential for the clinical development of Hsp90 inhibitors in SCLC.

PMID- 29594045 TI - Cumulative Doses to Brain and Other Critical Structures After Multisession Gamma Knife Stereotactic Radiosurgery for Treatment of Multiple Metastatic Tumors. AB - Purpose: Repeat stereotactic radiosurgery (SRS) is an attractive alternative to whole brain radiation therapy (WBRT) for treatment of recurrent brain metastases (BM). The purpose of this study is to determine the cumulative doses to the brain and critical normal structures in patients who underwent repeat courses of Gamma Knife (GK) SRS. Materials and methods: We retrospectively identified ten patients who received at least three GK-SRS sessions for multiply recurrent BM at our institution from 2013 to 2016. We used VelocityTM 3.1.0 software to co-register the magnetic resonance imaging images and the dose data of all treatment sessions for each patient. The cumulative doses to brain, lenses, eyes, brainstem, optic nerves, chiasm, and hippocampi were calculated. Dose-volume histograms, as well as the mean, median and maximum doses of these structures, were analyzed. Results: The median number of SRS was five sessions (range = 3-7 sessions) per patient over a median treatment span of 510 days (112-1,197 days), whereas the median number of metastatic tumors treated per patient was 25.0 (10-63). The median of the total tumor volume was 9.5 cc (2.3-75.9 cc). The median of the mean cumulative dose to the whole brain was 4.1 Gy (1.7-16.4 Gy). The medians of the maximum doses to the critical structures were as follows: brainstem, 6.1 Gy (2.2 28.9 Gy), chiasm, 3.9 Gy (1.8-10.8 Gy), right optic nerve, 2.9 Gy (1.2-9.0 Gy), and left optic nerve, 2.6 Gy (1.0-6.5 Gy). The medians of the mean and maximum cumulative doses to the hippocampi were 3.4 Gy (1.0-14.4 Gy) and 13.8 Gy (1.5 39.3 Gy), respectively. The median survival for the entire cohort was 26.7 months, and no patients developed radiation necrosis. Conclusion: Our study demonstrated that multisession GKSRS could be delivered with low cumulative doses to critical normal structures. Further studies are required to fully establish its role as an alternative treatment strategy to WBRT for the treatment of multiply recurrent BM.

AB - Altered surface glycosylation is a key feature of cancers, including gynecologic malignancies. Hypersialylation, the overexpression of sialic acid, is known to promote tumor progression and to dampen antitumor responses by mechanisms that also involve sialic acid binding immunoglobulin-like lectins (Siglecs), inhibitory immune receptors. Here, we discuss the expression patterns of Siglecs and sialyltransferases (STs) in gynecologic cancers, including breast, ovarian, and uterine malignancies, based on evidence from The Cancer Genome Atlas. The balance between sialosides generated by specific STs within the tumor microenvironment and Siglecs on leukocytes may play a decisive role for antitumor immunity. An interdisciplinary effort is required to decipher the characteristics and biological impact of the altered tumor sialome in gynecologic cancers and to exploit this knowledge to the clinical benefit of patients. PMID- 29594048 TI - In vivo Effects of Repeated Thyronamine Administration in Male C57BL/6J Mice. AB - Objectives: Thyronamines are decarboxylated and deiodinated metabolites of thyroid hormones (THs). Of all possible thyronamine variants, only 3 iodothyronamine (3-T1AM) and iodine-free thyronamine (T0AM) have been detected in vivo. While intensive research has been done on the (patho-)physiological action of 3-T1AM, the role of T0AM has been studied less intensively. Study Design: We determined whether a single pharmacological dose (50 mg/kg, i.p.) or repeated administration (5 mg/kg/day, i.p., for 7 days) of T0AM affects metabolism, cardiovascular function, or thermoregulation in male C57BL/6J mice. Since selenium (Se) is important for proper TH function and Se metabolism is affected by TH, we additionally analyzed Se concentrations in liver, serum, and kidney using total reflection X-ray analysis. Results: A single injection of T0AM had no effect on heart rate, temperature, or activity as assessed by radio telemetry. Likewise, daily administration of T0AM did not alter body weight, food or water intake, heart rate, blood pressure, brown adipose tissue thermogenesis, or body temperature, and no significant differences in hepatic glycogen content or mRNA expression of genes involved in cardiovascular function or metabolic control were determined. Also, the X-ray analysis of Se concentrations revealed no significant changes. However, hepatic T0AM was significantly increased in the treated animals. Conclusions: In summary, our data demonstrate that T0AM elicits no obvious metabolic, cardiovascular, or thermoregulatory activities in mice. As T0AM does also not interfere with TH or Se metabolism, we conclude that the deiodination of 3-T1AM to T0AM constitutes an efficient inactivation mechanism, terminating the actions of the more powerful precursor. PMID- 29594049 TI - Positron Emission Tomography (PET) and PET/CT in Thyroid Cancer: A Systematic Review and Meta-Analysis. AB - Background: Positron emission tomography (PET) and PET/CT are functional imaging methods that are widely used in diagnostic procedures in oncology. Objectives: The objective of this study was to assess the patient-relevant benefit of PET or PET/CT in patients with thyroid cancer based on a literature review and meta analysis. Methods: A systematic review including studies that had been published until December 2013 was performed. To be included, studies had to prospectively investigate patients with thyroid cancer in a clinical setting of staging, restaging, or diagnosing tumour recurrence. Results: Out of 3,506 potentially relevant articles, 29 studies were included. No study directly evaluated the benefits of PET. Twenty-eight studies dealt with the diagnostic accuracy of PET or PET/CT, and 1 study evaluated the prognostic value of PET/CT. The authors showed that a positive result of PET/CT in restaging patients with differentiated thyroid cancer yielded a significant decrease in overall survival (hazard ratio, HR 5.01, CI 3.41-6.62). In patients with suspected recurrence of differentiated thyroid cancer, meta-analysis showed higher sensitivity of PET (89.7%, CI 78-99%) and PET/CT (94.3%, CI 87-97%) compared with conventional imaging (65.4%, CI 32 88%) and comparable results for specificity. Due to the low numbers of studies and patients, meta-analyses on medullary carcinoma did not produce meaningful results. Conclusion: The patient-relevant benefits of PET or PET/CT in thyroid cancer could not be evaluated satisfactorily based on the included studies. It remains unclear whether higher diagnostic test accuracy leads to changes in therapeutic strategies and better patient-relevant outcomes. PMID- 29594050 TI - Ultrasound Measurements of Thyroid Gland Volume at 36 Weeks' Corrected Gestational Age in Extremely Preterm Infants Born before 28 Weeks' Gestation. AB - Background: Thyroid ultrasound is a non-invasive imaging tool and provides good evaluation of thyroid anatomy, location, vascularisation, and echogenicity. The aim of this study was to assess thyroid function and thyroid volume in extremely preterm infants born before 28 weeks' gestation evaluated at 36 weeks' corrected gestational age (CGA) compared to term infants' normative data in the literature. Design: In this largest prospective UK study of extremely premature infants born at less than 28 weeks' gestation, thyroid volume measurement was assessed at 36 weeks' CGA. Fifty-five extremely preterm infants (28 males) who were born before 28 weeks' gestation were recruited to the study. All infants had ultrasound assessment of the thyroid gland at 36 weeks' CGA. We also prospectively measured thyroid stimulating hormone (TSH) and free thyroxine (FT4) in all infants at the time of recruitment (within 5 days of birth), at days 14, 21, and 28, and at 36 weeks' CGA. Results: The mean thyroid volume was measured at 0.57 mL (SD +/ 0.18). There was no association between mean thyroid volume and thyroid function (TSH or FT4). No associations were found between mean thyroid volume and gestation or birth weight in these infants. Conclusions: Our findings provide a reference range with a mean thyroid volume of 0.57 mL (SD +/-0.18) in this extremely preterm age group if less than 28 weeks' gestation. Thyroid volume at birth can vary from country to country due to variations in iodine intake as well as gestational age. PMID- 29594051 TI - Vitamin D in Graves Disease: Levels, Correlation with Laboratory and Clinical Parameters, and Genetics. AB - Objective: The aim was to compare the vitamin D levels in patients with Graves disease (GD) with the general population and to correlate the vitamin D levels with laboratory and clinical parameters in GD. Moreover, we examined the genetic variation in genes involved in the vitamin D metabolism and their association with GD. Methods: The levels of vitamin D were compared in 292 patients with newly diagnosed GD and 2,305 controls. Single nucleotide polymorphisms (SNPs) in the vitamin D receptor (VDR), vitamin D binding protein (DBP), and 1-alpha hydroxylase (CYP27B1) were examined for association with GD and/or Graves ophthalmopathy (GO) in 708 patients and 1,178 controls. Results: Patients with GD had significantly lower vitamin D levels compared to controls (55.0 +/- 23.2 vs. 87.2 +/- 27.6 nmol/L, p < 0.001). In patients with GD (n = 219), there was no association between the levels of vitamin D at diagnosis and free thyroxine (fT4), free triiodothyronine (fT3), thyrotropin receptor antibodies (TRAb), GO at diagnosis, or relapse after terminating treatment with antithyroid drugs. Two SNPs in VDR were associated with GD: rs10735810 (OR = 1.36, 95% CI: 1.02-1.36, p = 0.02) and rs1544410 (OR = 1.47, 95% CI: 1.03-1.47, p = 0.02). There was no difference in the mean vitamin D level between genotypes in either rs10735810 or rs154410. Conclusions: Patients with GD had lower vitamin D levels compared to the general population; however, the vitamin D levels did not affect the laboratory or clinical parameters of GD. SNPs in the VDR influenced the risk of GD through mechanisms other than reducing the vitamin D levels. PMID- 29594052 TI - Parathyroid Hormone Assays following Total Thyroidectomy: Is There a Predictive Value? AB - Objectives: Parathyroid hormone (PTH) is a risk marker for hypoparathyroidism (hypoPTH). This study aimed to determine the predictive values of early PTH assays carried out at the moment of skin closure (PTH SC), to establish a treatment algorithm, identifying two threshold values. We assessed the reproducibility of this approach with two different immunoassay kits (hypoPTH) after total thyroidectomy, but its practical application is not consensual. Study Design: We conducted a prospective descriptive study, including all patients who underwent a total thyroidectomy between March 2012 and November 2013. Postoperative PTH SC levels, corrected calcium on postoperative days, and occurrence of hypoPTH symptoms were collected. Results: Of 257 patients, the rate of hypoPTH was 20%. Threshold values to obtain a 100% positive predictive value to identify patients for whom hypoPTH was absolutely certain were: PTH SC <7 ng/L for the Roche kit and PTH SC <4 ng/L for the Beckman-Coulter kit. Threshold values to obtain a 100% negative predictive value to identify patients for whom the absence of hypoPTH was absolutely certain were: PTH SC >=19 ng/L for the Roche kit and PTH SC >=9 ng/L the Beckman-Coulter kit. Conclusions: A single serum PTH sampled at skin closure is a reliable test to predict hypoPTH after a total thyroidectomy. The use of a threshold based on a 100% negative predictive value enables patients with no risk of hypoPTH to be safely discharged within the first 24 h postoperatively without unnecessary calcium and vitamin treatment. This medication can be given promptly to patients at risk of hypoPTH to limit the occurrence of hypocalcaemia. PMID- 29594053 TI - Indeterminate Thyroid Nodules: A Pragmatic Approach. AB - Background: Fine needle aspiration (FNA) cytology fails to provide a conclusive diagnosis in a subset of thyroid lesions labeled as "indeterminate" (Thy3). In this study, we aimed at ascertaining the prevalence of Thy3 thyroid nodules in a hitherto unreported ethnic group (residents of the United Arab Emirates). Methods: We retrospectively examined 688 FNA of the thyroid performed on 584 patients. Samples were reported using the Royal College of Physicians' (RCP) Thy classification. The results of the FNA were correlated with the final surgical specimens. Ultrasonography (US) risk stratification was calculated using a web based US risk of malignancy calculator. Results: Overall sample adequacy was 97%. The indeterminate group Thy3 was found in 7% of the samples. The overall risk of malignancy in the Thy3 category was 20%. This risk was very similar in the 2 subgroups of Thy3 (17% in Thy 3a and 22% in Thy3f). Subdividing the Thy3 group into subgroups becomes less necessary if the US scoring is <24.5% since the negative predictive value, in this case, is 100%. Applying this criterion to our population would have had the potential of reducing the percentage of patients referred to surgery from 61 to 43%. Conclusions: Proper risk stratification of Thy3 lesions should be based on the combined risk assessment of clinical, cytological, radiological, and molecular data. Such a pragmatic approach is expected to reduce the percentage of inappropriate referrals to surgery. PMID- 29594054 TI - A Case Report of Syndromic Multinodular Goitre in Adolescence: Exploring the Phenotype Overlap between Cowden and DICER1 Syndromes. AB - Background: Hereditary tumour predisposition syndromes may increase the risk for development of thyroid nodules at a young age. We present the case of an adolescent female with Cowden syndrome who had some atypical phenotypic features which overlapped with the DICER1 syndrome. Material and Methods: A 17-year-old female presented with a 3-month history of progressive right neck swelling. Fine needle cytology of the thyroid revealed a follicular neoplasm with features suggestive of follicular variant of papillary thyroid carcinoma and she underwent a hemithyroidectomy. Enlarging nodules in the remaining thyroid led to a completion thyroidectomy at 19 years of age. The patient's past medical history included an ovarian mixed malignant germ cell tumour, pulmonary nodules and cysts, renal cysts, mucocutaneous lesions, an arachnoid cyst, and a fibrous breast lesion. Macrocephaly was noted on physical examination. Results: Based on the patient's complex phenotype and young age, a hereditary predisposition syndrome was suspected and genetic testing of PTEN and DICER1 was undertaken. A heterozygous truncating germ-line PTEN mutation was identified, which combined with clinical findings, met criteria for the diagnosis of Cowden syndrome. Additional loss of heterozygosity of the wild-type PTEN allele was detected in the right thyroid lesion and ovarian tumour. No DICER1 mutations were identified. Conclusions: Genetic testing was crucial in elucidating this patient's predisposition to the early development of neoplastic and non-neoplastic conditions. Our report also highlights the phenotypic overlap between the Cowden and DICER1 syndromes and illustrates the importance of recognising the variable phenotypic features of hereditary syndromes in order to enable timely implementation of appropriate care. PMID- 29594055 TI - Occurrence of Graves' Orbitopathy and Graves' Hyperthyroidism after a Trauma to the Eye. AB - Background: Graves' orbitopathy (GO) is believed to be the consequence of autoimmunity against antigens that are present both in the thyroid and orbital tissues. Massive release of thyroid antigens causes the appearance or deterioration of GO in patients with Graves' hyperthyroidism (GH), as it occurs following radioiodine treatment. In theory, a similar release of autoantigens may occur at the eye level, for example due to an orbital trauma or surgical manipulation. To our knowledge, this is the first report of a case of de novo appearance of GO and then GH after an eye trauma, possibly reflecting spreading of autoantigens and activation of the immune system against shared orbital and thyroid antigens. Case Report: An otherwise healthy, 57-year-old man presented 6 months after the appearance of a monolateral right orbitopathy, which occurred 40 days after a trauma in the ipsilateral eye. His thyroid function was normal, with positive serum anti-TSH receptor autoantibodies. The thyroid was normal on ultrasound. A month later he developed hyperthyroidism and orbitopathy in the left eye. Discussion: The development of GO after an eye trauma may reflect tissue damage with release of autoantigens and consequent autoimmunity in a predisposed individual (our patient had a familial history of autoimmune thyroid disease). The subsequent development of hyperthyroidism is in keeping with the hypothesis that GH and GO are due to autoimmunity against antigens present both in the thyroid and in orbital tissues. PMID- 29594056 TI - 2018 European Thyroid Association (ETA) Guidelines for the Management of Amiodarone-Associated Thyroid Dysfunction. AB - Treatment with amiodarone is associated with changes in thyroid function tests, but also with thyroid dysfunction (amiodarone-induced hypothyroidism, AIH, and amiodarone-induced thyrotoxicosis, AIT). Both AIH and AIT may develop in apparently normal thyroid glands or in the presence of underlying thyroid abnormalities. AIH does not require amiodarone withdrawal, and is treated with levothyroxine replacement if overt, whereas subclinical forms may be followed without treatment. Two main types of AIT are recognized: type 1 AIT (AIT 1), a form of iodine-induced hyperthyroidism occurring in nodular goitres or latent Graves disease, and type 2 AIT (AIT 2), resulting from destructive thyroiditis in a normal thyroid gland. Mixed/indefinite forms exist due to both pathogenic mechanisms. AIT 1 is best treated with thionamides that may be combined for a few weeks with sodium perchlorate to make the thyroid gland more sensitive to thionamides. AIT 2 is treated with oral glucocorticoids. Once euthyroidism has been restored, AIT 2 patients are followed up without treatment, whereas AIT 1 patients should be treated with thyroidectomy or radioiodine. Mixed/indefinite forms of AIT are treated with thionamides. Oral glucocorticoids can be added from the beginning if a precise diagnosis is uncertain, or after a few weeks if response to thionamides alone is poor. The decision to continue or to stop amiodarone in AIT should be individualized in relation to cardiovascular risk stratification and taken jointly by specialist cardiologists and endocrinologists. In the presence of rapidly deteriorating cardiac conditions, emergency thyroidectomy may be required for all forms of AIT. PMID- 29594057 TI - Thyroid Cancer Induction: Nitrates as Independent Risk Factors or Risk Modulators after Radiation Exposure, with a Focus on the Chernobyl Accident. AB - In recent decades, differentiated thyroid cancer (DTC) incidence has been increasing worldwide. The important contributions to this phenomenon of "overdiagnosis" driven by wider use of improved ultrasound systems are amply documented, notwithstanding the "real" carcinogenic effects of ionizing radiation, e.g., from the Chernobyl accident or health care interventions. Less well understood is the role of nitrates - as environmental pollutants, in diet, and in medication - in thyroid carcinogenesis. Increasing exposure to nitrates is associated with rising incidence of esophageal, stomach, bladder, and colon cancers. Recent data suggest that in agricultural areas with higher mean nitrate levels in groundwater, DTC risk is also elevated. Our work in Belarus after Chernobyl has shown that children in districts with high nitrate concentrations in drinking water had significantly higher thyroid cancer incidence after irradiation than did their counterparts in areas with lower nitrate concentrations. Notwithstanding thyroid shielding, increasing use of computed tomography and dental X-rays heightens radiation exposure of the salivary glands in the general population, especially in children and adolescents. When nitrate intake is increased, salivary gland irradiation may potentially result in carcinogenic elevations in plasma nitric oxide concentrations. In conclusion, excess nitrate intake seems to be an independent risk factor for DTC. Additionally, we hypothesize from our data that high nitrate levels modulate the carcinogenic effect of radiation on the thyroid. Cohort studies, case-control studies, or both, are needed to quantify the effects of nitrates on DTC risk in the presence or absence of radiation exposure, e.g., that associated with diagnostic or therapeutic health care interventions. PMID- 29594058 TI - Trends in Costs of Thyroid Disease Treatment in Denmark during 1995-2015. AB - Background: Iodine fortification (IF) may contribute to changes in costs of thyroid disease treatment through changes in disease patterns. From a health economic perspective, assessment of the development in costs of thyroid disease treatment in the population is pertinent. Objectives: To assess the trends in annual medicine and hospital costs of thyroid disease treatment during 1995-2015 in Denmark, i.e., before and after the introduction of mandatory IF in 2000. Methods: Information on treatments for thyroid disease (antithyroid medication, thyroid hormone therapy, thyroid surgery, and radioiodine treatment) was obtained from nationwide registers. Costs were valued at 2015 prices using sales prices for medicines and the Danish Diagnosis-Related Group (DRG) and Danish Ambulatory Grouping System (DAGS) tariffs of surgeries/radioiodine treatments. Results were adjusted for changes in population size and age and sex distribution. Results: The total direct medicine and hospital costs of thyroid disease treatment increased from EUR ~190,000 per 100,000 persons in 1995 to EUR ~270,000 per 100,000 persons in 2015. This was mainly due to linearly increased costs of thyroid hormone therapy and increased costs of thyroid surgery since 2008. Costs of antithyroid medication increased slightly and transiently after IF, while costs of radioiodine treatment remained constant. Costs of thyroid hormone therapy and thyroid surgery did not follow the development in the prevalence of hypothyroidism and structural thyroid diseases observed in concurrent studies. Conclusion: The costs of total direct medicine and hospital costs for thyroid disease treatment in Denmark increased from 1995 to 2015. This is possibly due to several factors, e.g., changes in treatment practices, and the direct effect of IF alone remains to be estimated. PMID- 29594059 TI - Severe Inflammatory Ophthalmopathy in a Euthyroid Patient during Nivolumab Treatment. AB - Introduction: Nivolumab is a promising treatment in patients with advanced malignancies. Among immune-related adverse events, autoimmune thyroid disorders are frequently reported. Patient: A 61-year-old male patient had no history of familial or personal thyroid disease. In 2012, this patient, a heavy smoker, presented with non-small-cell lung cancer that was treated with radiotherapy and chemotherapy. In 2015, the cancer progressed with cervical compressive symptoms, and the patient was treated with nivolumab. Results: After 3 infusions, bilateral eyelid ptosis and bilateral conjunctival redness with chemosis were observed. Ophthalmologic examination revealed severe proptosis with complete ophthalmoplegia but with normal vision, color test, and optic disk. Thyroid function tests were normal (TSH = 0.65 mU/L, free T4 = 15.4 pmol/L) without anti thyroperoxidase or anti-TSH receptor antibodies. CT scan of the orbits confirmed marked bilateral proptosis with expansion of the orbital adipose tissue without significant thickening of extraocular muscles. T2-weighted MRI showed inflammation of orbital adipose tissue. Nivolumab treatment was withdrawn, and the patient received weekly intravenous high-dose methylprednisolone (1 g for 2 weeks, 500 mg for 4 weeks, and 250 mg for 5 weeks). After the first 3 cycles, significant improvement of left chemosis was observed whereas bilateral ptosis and ophthalmoplegia were unchanged. The patient was euthyroid without thyroid autoimmunity 1 week prior to his death due to massive hemoptysis. Conclusion: We report severe inflammatory ophthalmopathy in a euthyroid patient with non-small cell lung cancer during nivolumab therapy. The occurrence of such ophthalmic adverse events is likely to increase during nivolumab therapy in patients with advanced malignancies. PMID- 29594060 TI - Prevalence of Radiological Signs of Dysthyroid Optic Neuropathy in Magnetic Resonance Imaging in Patients with Active, Moderate-to-Severe, and Very Severe Graves Orbitopathy. AB - Background: Differentiating between dysthyroid optic neuropathy (DON), which requires urgent therapy to prevent blindness, and moderate-to-severe Graves orbitopathy (GO) remains challenging. There is no pathognomonic feature of DON in either ophthalmological or radiological examinations. Objectives: Our aim was to investigate the prevalence of radiological signs of DON in magnetic resonance imaging (MRI) in patients with moderate-to-severe and very severe GO. Methods: Two researchers reassessed MRI scans of 23 consecutive patients (46 eyes) with active, moderate-to-severe GO and 14 patients (23 eyes) with very severe GO. Typical signs of DON in MRI include apical crowding and optic nerve stretching. These were evaluated in the eyes of both groups of patients. Lack of cerebrospinal fluid in the optic nerve sheath as well as muscle index values were also studied. These clinical evaluations and laboratory results were then compared between groups. Results: At least one of the typical radiological features of DON was found in 22 (96%) and 16 (35%) eyes with very severe and moderate-to-severe GO, respectively. Each occurred statistically more often in patients with very severe GO. There were no ophthalmological signs of very severe GO observed in the group of patients with moderate-to-severe GO during the study or its subsequent follow-up (234 weeks). Conclusions: MRI is a useful tool in evaluating very severe GO. However, features typical for DON are also found in up to 35% of eyes in patients with active, moderate-to-severe GO. Therefore, ophthalmological evaluation seems to be most important in the recognition of very severe GO. PMID- 29594061 TI - Effects of Chronic Lymphocytic Thyroiditis on the Clinicopathological Features of Papillary Thyroid Cancer. AB - Background: The effects of chronic lymphocytic thyroiditis (CLT) on the presentation and outcome of papillary thyroid carcinoma (PTC) have long been a topic of controversy. Objective: To evaluate the effect of coexistent CLT on the clinicopathological features of PTC. Design: Retrospective study. Patients: All patients with PTC who had been followed by the 2 co-investigators (Juan Rivera and Richard J. Payne) between 2006 and 2011 were included. Results: CLT was present in 35% (166) of the included patients and was associated with a higher proportion of patients with TNM stage I (p = 0.027) and fewer patients with persistent disease (p = 0.014) in comparison with the PTC-only group. Analysis of the data based on age (<45 or >45 years) revealed that in the older group, the presence of CLT was associated with fewer patients with persistent disease (p = 0.03) and capsular invasion (p = 0.05). However, in patients <45 years of age, the presence of CLT was associated with more capsular invasion (p = 0.003) and extrathyroidal extension (p = 0.004) compared with the PTC-only group. Conclusions: CLT in patients with PTC was associated with lower-stage disease and less disease persistence in patients >45 years of age. In patients <45 years, the presence of CLT appeared to be associated with unfavorable pathological features. PMID- 29594062 TI - Liposarcoma of the Thyroid: A Case Report with a Review of the Literature. AB - Background: Liposarcomas of the thyroid gland are extremely rare tumors, and, to our knowledge, only 12 cases have been reported in the English literature. An accurate diagnosis is challenging due to the nonspecific clinical presentation of this cancer, frequently defined just by a swelling of the neck. Patient Findings: We present an 82-year-old woman with liposarcoma of the thyroid, complaining of a fast-growing neck mass. MRI and neck ultrasound showed a large lipomatous mass, which corresponded to a cold nodule in the thyroid scan. After performing a total thyroidectomy, the diagnosis of a well-differentiated liposarcoma of the thyroid gland was made, showing an MDM2 amplification in fluorescence in situ hybridization. Since neither a metastasis nor a residual tumor was found, no further adjuvant therapy was needed. Results: We searched the literature for previous case reports and identified only 12 cases worldwide to form our database. A demographic as well as clinical and histopathological analysis was made. In most cases, the liposarcoma occurred in patients >60 years of age. All histological subtypes, such as well-differentiated and myxoid liposarcomas, and pleomorphic and dedifferentiated liposarcomas, were found in the literature. In only 38.46% of the cases, an infiltration of the adjacent organs was observed. Surgery was the most common treatment chosen. Conclusions: Our review provides clinical and histopathological features of a primary liposarcoma of the thyroid to enable the identifi-cation of this rare tumor entity and assist in the decision-making process regarding therapeutic options and tumor follow-up. PMID- 29594063 TI - Inbred Rats as a Model to Study Persistent Renal Leptospirosis and Associated Cellular Immune Responsiveness. AB - Pathogenic species of Leptospira cause leptospirosis, a bacterial zoonotic disease with a global distribution affecting over one million people annually. Rats are regarded as one of the most significant reservoir hosts of infection for human disease, and in the absence of clinical signs of infection, excrete large numbers of organisms in their urine. A unique biological equilibrium exists between pathogenic leptospires and reservoir hosts of infection, but surprisingly, little is known concerning the host's cellular immune response that facilitates persistent renal colonization. To address this deficiency, we established and applied an immunocompetent inbred rat model of persistent renal colonization; leptospires were detected in urine of experimentally infected rats by 3 weeks post-infection and remained positive until 8 weeks post-infection. However, there was little, if any, evidence of inflammation in colonized renal tubules. At 8 weeks post-infection, a robust antibody response was detected against lipopolysaccharide and protein outer membrane (OM) components. Purified B and T cells derived from the spleen of infected and non-infected rats proliferated in response to stimulation with 0.5 MUg of OM fractions of Leptospira, including CD4+ T cells, which comprised 40% of proliferating cells, compared to 25% in non-infected controls. However, analysis of gene expression did not determine which immunoregulatory pathways were activated. Lymphocytes purified from the lymph node draining the site of colonization, the renal lymph node, also showed an increase in percentage of proliferating B and T cells. However, in contrast to a phenotype of 40% CD4+ T cells in the spleen, the phenotype of proliferating T cells in the renal lymph node comprised 65% CD4+ T cells. These results confirm that the renal lymph node, the local lymphoid organ, is a dominant site containing Leptospira reactive CD4+ T cells and highlight the need to consider the local, vs. systemic, immune responses during renal colonization infection. The use of inbred immunocompetent rats provides a novel tool to further elucidate those pathophysiological pathways that facilitate the unique biological equilibrium observed in reservoir hosts of leptospirosis.

PMID- 29594066 TI - A Simple and Rapid Gene Disruption Strategy in Mycobacterium abscessus: On the Design and Application of Glycopeptidolipid Mutants. AB - Little is known about the disease-causing genetic determinants that are used by Mycobacterium abscessus, increasingly acknowledged as an important emerging pathogen, notably in cystic fibrosis. The presence or absence of surface exposed glycopeptidolipids (GPL) conditions the smooth (S) or rough (R) M. abscessus subsp. abscessus (M. abscessus) variants, respectively, which are characterized by distinct infective programs. However, only a handful of successful gene knock out and conditional mutants have been reported in M. abscessus, testifying that genetic manipulation of this mycobacterium is difficult. To facilitate gene disruption and generation of conditional mutants in M. abscessus, we have designed a one-step single cross-over system that allows the rapid and simple generation of such mutants. Cloning of as small as 300 bp of the target gene allows for efficient homologous recombination to occur without additional exogenous recombination-promoting factors. The presence of tdTomato on the plasmids allows easily sifting out the large background of mutants spontaneously resistant to antibiotics. Using this strategy in the S genetic background and the target gene mmpL4a, necessary for GPL synthesis and transport, nearly 100% of red fluorescent clones exhibited a rough morphotype and lost GPL on the surface, suggesting that most red fluorescent colonies obtained after transformation incorporated the plasmid through homologous recombination into the chromosome. This system was further exploited to generate another strain with reduced GPL levels to explore how the presence of these cell wall-associated glycolipids influences M. abscessus hydrophobicity as well as virulence in the zebrafish model of infection. This mutant exhibited a more pronounced killing phenotype in zebrafish embryos compared to its S progenitor and this effect correlated with the production of abscesses in the central nervous system. Overall, these results suggest that the near-complete absence of GPL on the bacterial surface is a necessary condition for optimal pathogenesis of this mycobacterium. They also suggest that GPL content affects hydrophobicity of M. abscessus, potentially altering the aerosol transmission, which is of particular importance from an epidemiological and clinical perspective. PMID- 29594067 TI - Route of Glucose Uptake in the Group a Streptococcus Impacts SLS-Mediated Hemolysis and Survival in Human Blood. AB - The transport and metabolism of glucose has been shown to have far reaching consequences in the transcriptional profile of many bacteria. As glucose is most often the preferred carbon source for bacteria, its presence in the environment leads to the repression of many alternate carbohydrate pathways, a condition known as carbon catabolite repression (CCR). Additionally, the expression of many virulence factors is also dependent on the presence of glucose. Despite its importance, little is known about the transport routes of glucose in the human pathogen Streptococcus pyogenes. Considering that Streptococcus pyogenes is an important human pathogen responsible for over 500,000 deaths every year, we characterized the routes of glucose transport in an effort to understand its importance in GAS pathogenesis. Using a deletion of glucokinase (DeltanagC) to block utilization of glucose imported by non-PTS pathways, we determined that of the two glucose transport pathways in GAS (PTS and non-PTS), the non-PTS pathway played a more significant role in glucose transport. However, the expression of both pathways is linked by a currently unknown mechanism, as blocking the non-PTS uptake of glucose reduces ptsI (EI) expression. Similar to the effects of the deletion of the PTS pathway, lack of the non-PTS pathway also leads to the early activity of Streptolysin S. However, this early activity did not adversely or favorably affect survival of DeltanagC in whole human blood. In a subcutaneous murine infection model, DeltanagC-infected mice showed increased lesion severity at the local site of infection; although, lesion size and dissemination from the site of infection was similar to wild type. Here, we show that glucose transport in GAS is primarily via a non-PTS pathway. The route of glucose transport differentially affects the survival of GAS in whole human blood, as well as the lesion size at the local site of infection in a murine skin infection model. PMID- 29594068 TI - Construction of a New Phage Integration Vector pFIV-Val for Use in Different Francisella Species. AB - We recently identified and described a putative prophage on the genomic island FhaGI-1 located within the genome of Francisella hispaniensis AS02-814 (F. tularensis subsp. novicida-like 3523). In this study, we constructed two variants of a Francisella phage integration vector, called pFIV1-Val and pFIV2-Val (Francisella Integration Vector-tRNAVal-specific), using the attL/R-sites and the site-specific integrase (FN3523_1033) of FhaGI-1, a chloramphenicol resistance cassette and a sacB gene for counter selection of transformants against the vector backbone. We inserted the respective sites and genes into vector pUC57 Kana to allow for propagation in Escherichia coli. The constructs generated a circular episomal form in E. coli which could be used to transform Francisella spp. where FIV-Val stably integrated site specifically into the tRNAVal gene of the genome, whereas pUC57-Kana is lost due to counter selection. Functionality of the new vector was demonstrated by the successfully complementation of a Francisella mutant strain. The vectors were stable in vitro and during host-cell infection without selective pressure. Thus, the vectors can be applied as a further genetic tool in Francisella research, expanding the present genetic tools by an integrative element. This new element is suitable to perform long-term experiments with different Francisella species. PMID- 29594069 TI - Tetrahymena thermophila Predation Enhances Environmental Adaptation of the Carp Pathogenic Strain Aeromonas hydrophila NJ-35. AB - Persistence of Aeromonas hydrophila in aquatic environments is the principle cause of fish hemorrhagic septicemia. Protistan predation has been considered to be a strong driving force for the evolution of bacterial defense strategies. In this study, we investigated the adaptive traits of A. hydrophila NJ-35, a carp pathogenic strain, in response to Tetrahymena thermophila predation. After subculturing with Tetrahymena, over 70% of A. hydrophila colonies were small colony variants (SCVs). The SCVs displayed enhanced biofilm formation, adhesion, fitness, and resistance to bacteriophage infection and oxidative stress as compared to the non-Tetrahymena-exposed strains. In contrast, the SCVs exhibited decreased intracellular bacterial number in RAW264.7 macrophages and were highly attenuated for virulence in zebrafish. Considering the outer membrane proteins (OMPs) are directly involved in bacterial interaction with the external surroundings, we investigated the roles of OMPs in the antipredator fitness behaviors of A. hydrophila. A total of 38 differentially expressed proteins were identified in the SCVs by quantitative proteomics. Among them, three lipoproteins including SurA, Slp, and LpoB, and a serine/threonine protein kinase (Stpk) were evidenced to be associated with environmental adaptation of the SCVs. Also, the three lipoproteins were involved in attenuated virulence of SCVs through the proinflammatory immune response mediated by TLR2. This study provides an important contribution to the understanding of the defensive traits of A. hydrophila against protistan predators. PMID- 29594064 TI - Metazoan Parasite Vaccines: Present Status and Future Prospects. AB - Eukaryotic parasites and pathogens continue to cause some of the most detrimental and difficult to treat diseases (or disease states) in both humans and animals, while also continuously expanding into non-endemic countries. Combined with the ever growing number of reports on drug-resistance and the lack of effective treatment programs for many metazoan diseases, the impact that these organisms will have on quality of life remain a global challenge. Vaccination as an effective prophylactic treatment has been demonstrated for well over 200 years for bacterial and viral diseases. From the earliest variolation procedures to the cutting edge technologies employed today, many protective preparations have been successfully developed for use in both medical and veterinary applications. In spite of the successes of these applications in the discovery of subunit vaccines against prokaryotic pathogens, not many targets have been successfully developed into vaccines directed against metazoan parasites. With the current increase in omics technologies and metadata for eukaryotic parasites, target discovery for vaccine development can be expedited. However, a good understanding of the host/vector/pathogen interface is needed to understand the underlying biological, biochemical and immunological components that will confer a protective response in the host animal. Therefore, systems biology is rapidly coming of age in the pursuit of effective parasite vaccines. Despite the difficulties, a number of approaches have been developed and applied to parasitic helminths and arthropods. This review will focus on key aspects of vaccine development that require attention in the battle against these metazoan parasites, as well as successes in the field of vaccine development for helminthiases and ectoparasites. Lastly, we propose future direction of applying successes in pursuit of next generation vaccines. PMID- 29594070 TI - Autophagy and Ubiquitination in Salmonella Infection and the Related Inflammatory Responses. AB - Salmonellae are facultative intracellular pathogens that cause globally distributed diseases with massive morbidity and mortality in humans and animals. In the past decades, numerous studies were focused on host defenses against Salmonella infection. Autophagy has been demonstrated to be an important defense mechanism to clear intracellular pathogenic organisms, as well as a regulator of immune responses. Ubiquitin modification also has multiple effects on the host immune system against bacterial infection. It has been indicated that ubiquitination plays critical roles in recognition and clearance of some invading bacteria by autophagy. Additionally, the ubiquitination of autophagy proteins in autophagy flux and inflammation-related substance determines the outcomes of infection. However, many intracellular pathogens manipulate the ubiquitination system to counteract the host immunity. Salmonellae interfere with host responses via the delivery of ~30 effector proteins into cytosol to promote their survival and proliferation. Among them, some could link the ubiquitin-proteasome system with autophagy during infection and affect the host inflammatory responses. In this review, novel findings on the issue of ubiquitination and autophagy connection as the mechanisms of host defenses against Salmonella infection and the subverted processes are introduced. PMID- 29594072 TI - Tonsillar Lymphoma in Children According to Age Group: A Systematic Review. AB - Introduction: Lymphoma is a common malignant tumor of the head and neck occurring during childhood. Early diagnosis is very important in terms of prognosis in patients with tonsillar lymphoma.Our objective was to evaluate the clinical manifestations of pediatric tonsillar lymphoma according to different age groups. Materials and Methods: A systematic review of available English, Spanish, or Portuguese literature from January 1996 to June 2012 was performedin the BIREME, Cochrane, IBECS, Lilacs, PubMed/Medline, SCIELO, and Scopus databases, using "tonsillar lymphoma" and "children" as keywords. Inclusion criteria were pediatric case reports, patients aged up to 18 years, and information on clinical features at the time of diagnosis. Results: Out of 87 identified publications, 13 articles were selected describing 53 patients. Tonsillar asymmetry was the most common sign. Snoring is a common sign in patients aged under 5 years; clinical lymphadenopathy is frequent among patients aged between 6 and 10 years; and dysphagia is a common sign in patients between 11 and 18 years of age. Burkitt's lymphoma is the most common form among all ages studied, followed by B-cell lymphoma. Conclusion: Clinical manifestations differ according to age group. However, tonsillar asymmetry is the most frequent sign regardless of age group. PMID- 29594071 TI - Ecological Restoration of Antibiotic-Disturbed Gastrointestinal Microbiota in Foregut and Hindgut of Cows. AB - Antibiotically disturbed gastrointestinal microbiota needs a long period time to be restored to normal, which may cause a series of problems to the host. The understanding of restoration of the biased microbiota by antibiotics remains largely unknown. Here, we investigated the microbiota shift in foregut (rumen) and hindgut (rectum) of lactating cows after antibiotics exposure as well as after antibiotics withdrawal with (Microbiota transplantation, MT group) or without (Control, CON group) microbiota transplantation. We were able to demonstrate that microbiota in both foregut and hindgut significantly changed after 3 or 14 days of antibiotics exposure, and the changes persisted over long period of time (>18 days) after withdrawing the antibiotics. We further observed a faster restoration of microbiota in both foregut and hindgut of MT group than CON group, microbiota in foregut was mainly benefited from microbiota transplantation by restoring the alpha-diversity as well as within-group similarity, while microbiota in hindgut was primarily benefited from microbiota transplantation by reestablishing the co-occurrence network (nodes number, edges number, density, modularity as well as closeness centrality). These results together expanded our understanding of restoration of the biased microbiota by antibiotics, and may also be instructive to deal with the delayed microbiota restoration at least in cows. PMID- 29594073 TI - Enhancing Working Memory Capacity in Persian Cochlear Implanted Children: A Clinical Trial Study. AB - Introduction: Sensory deprivations such as hearing impairment that affect sensory input have a secondary impact on cognitive functions such as working memory (WM). WM capacity is an important cognitive component that processes language-related activities. Moreover, several studies have shown a deficit in WM in children with a cochlear implant (CI). We aimed to assess the performance of children with CIs in pre- and post-training sessions and compare their scores on a battery of WM tests to investigate the efficacy of a WM training program. Materials and Methods: Twenty-five children aged 7-10 years with a CI participated in this study. To train their WM, a computer game was used. In order to examine auditory WM, a test battery including standardized digit span (forward and backward variations), non-word and sentence repetition (subtest of the Test of Language Development-Primary) were assessed in pre- and post-training test sessions at Shiraz Implant Center. Results: There were statistically significant differences between pre- and post-training test scores on all subtests. Test score differences were statistically significant for forward digit span (P=0.003), backward digit span (P=0.001), non-word repetition (P=0.001), and sentence repetition tasks (P=0.003) before and after training sessions. Conclusion: Training may enhance WM capacity. With regards to the importance of WM in literacy and learning, it seems applying such intervention programs may be helpful in the rehabilitation of implanted children. PMID- 29594074 TI - Effect of Early Vestibular Rehabilitation on Vertigo and Unsteadiness in Patients with Acute and Sub-Acute Head Trauma. AB - Introduction: Vestibular rehabilitation is a treatment option for the management of vertigo and unsteadiness, which are very common in head trauma patients and more challenging in the early months after trauma. This study evaluated the effectiveness of a vestibular rehabilitation program in the recovery of acute and sub-acute head trauma patients. The goal of this study was evaluation of the effect of early vestibular rehabilitation on patients with acute and sub-acute head trauma. Materials and Methods: This study was performed in 20 head trauma patients with vertigo and unsteadiness. The patients were randomly divided into two groups: one group received medical therapy (Betaserc) and the other received rehabilitation and medical therapy. An individualized vestibular rehabilitation program was designed that was then revised and verified by a joint committee of vestibular rehabilitation groups. The effectiveness of interventions was measured using the Dizziness Handicap Inventory (DHI) by comparing the results before and after therapy. Results: The physical conditions and DHI scores of patients in both groups were similar at baseline. After 1 month of rehabilitation, patients receiving vestibular rehabilitation and medication showed greater progress than patients receiving medication only (P=0.000). Conclusion: Vestibular rehabilitation can aid in the recovery from vertigo and increase the stability of head trauma patients. Simultaneous treatment with medicine and vestibular rehabilitation exercises can result in quicker and better therapeutic effects. PMID- 29594075 TI - Islamic Attitudes and Rhinoplasty. AB - Introduction: Although the psychological aspects of rhinoplasty have been fully investigated in the medical literature, the religiosity of rhinoplasty candidates has not been taken into consideration. Materials and Methods: In this cross sectional study, the religious attitudes of 157 rhinoplasty candidates were compared with those of 74 subjects who had not requested rhinoplasty. A domestic validated reliable questionnaire was completed by all subjects to classify them with respect to religious attitude. Other factors such as age, sex and economic and educational status were also taken into consideration. From the surgeon's perspective, subjects were put into three categories: subjects who had a relative indication for rhinoplasty (Category.1), subjects with a well-defined nose based on accepted standards of facial aesthetic analysis (Category.2) and finally subjects with a severely deformed nose, such as deviated nose or nasal cleft lip deformity (Category.3). Results: The mean age among subjects was 28.63 +/- 7.05 years, and the majority were female (87%). The two groups of participants (those who did and did not express a desire for rhinoplasty) were analyzed from the point view of age, sex, economic and educational status. The economic and educational status of the two groups did not differ significantly (P>0.05). The religious score showed a significant difference between those who were interested in rhinoplasty (122.75+/-23.49) and those were not interested (138.78+/-21.85; P<0.001). Conclusion: Religion may affect a patient's decision to undergo rhinoplasty surgery, such that persons with a higher religious attitude tend to undertake it less often. However, individuals with major nasal deformities tend to decide undertake the surgery, irrespective of religious beliefs. PMID- 29594076 TI - Translation, Cross-Cultural Adaptation, Validation and Reliability of the Northwestern Dysphagia Patient Check Sheet (NDPCS) in Iran. AB - Introduction: Speech and language therapists (SLTs) require proper tools to detect dysphagia in the early stages. One of these screening tools is the Northwestern Dysphagia Patient Check Sheet (NDPCS). However, this tool needs to be adapted, validated, and shown to be reliable for the Persian culture. The aim of the present study was to report the validity and reliability of the Persian NDPCS (P-NDPCS). Materials and Methods: The NDPCS has 28 items and five sections. Beaton's guidelines were followed in terms of the translation process. To report the content validity index (CVI) and the content validity ratio (CVR), eight SLTs experienced in swallowing disorders examined the content and face validities of the P-NDPCS in terms of the quality of translation, fluency, understandability, and the cultural context. In total, 140 patients with neurogenic and mechanical dysphagia were evaluated using the P-NDPCS. Internal consistency reliability was investigated using the Kuder-Richardson formula 20. The interclass correlation coefficient (ICC) was used for test-retest reliability. Results: The P-NDPCS preserved the 28 items and the five categories of the original version. However, semantic and food adjustments were applied due to cultural differences. The scoring system was changed from safe/unsafe to yes/no for four subsections and to normal/abnormal for the oromotor section. Food requirements were also changed. The CVR and CVI were both 75%. The P-NDPCS was shown to have good content validity. The internal reliability was 0.95, indicating excellent reliability. Conclusion: The equivalence between the original version of the NDPCS and the P NDPCS was preserved. Our findings indicate that the P-NDPCSis a valid and reliable screening tool for the diagnosis of dysphagia in the early phase. PMID- 29594077 TI - Results of Type I Tympanoplasty Using Fascia with or without Cartilage Reinforcement: 10 Years' Experience. AB - Introduction: There remains controversy about the optimal kind of graft to repair tympanic membrane. The purpose of this study was to evaluate the anatomical and auditory outcomes of type I tympanoplasty using fascia with or without cartilage reinforcement. Materials and Methods: This retrospective cohort study was conducted from 2005 to 2015. All cases were surgically treated by a single surgeon. We excluded cases in which the etiology of chronic otitis media was cholesteatoma. According to the use of cartilage reinforcement in the posterosuperior part of the graft, patients were divided into two groups, and the results of anatomical and auditory evaluation were compared between the two groups. The anatomical outcome was grafting success and the auditory outcome was improvement of air bone gap (ABG). Results: A total of 320 patients were classified in Group A (tympanoplasty with fascia temporalis only) and 346 were in Group B (tympanoplasty with cartilage reinforcement). All patients were followed for at least 2 years. The overall success rate in the two groups was 91.6% and 93.4%, respectively (P=0.3). The most common cause of failure in the two groups was re-perforation (5.6% and 3.8%, respectively). The improvement of ABG in two groups was 18.5 dB and 3.2 dB, respectively. The difference between two groups was statistically significant (P<0.001). Conclusion: In patients with dry perforation of the tympanic membrane, the anatomical success with tympanoplasty with fascia only or with cartilage reinforcement was similar. However, hearing improvement in the fascia only group was greater than in the group undergoing cartilage reinforcement. PMID- 29594078 TI - Malignant Melanoma of the External Auditory Canal: A Rare Entity. AB - Introduction: Although malignant melanomas (MM) are common in the head and neck region; primary malignant melanoma of the external auditory canal (EAC) is rare. Case Report: We present the case of a 50-year-old symptomatic man with a malignant melanoma of the external auditory canal, which clinically masqueraded as a haemangioma. The patient subsequently developed extensive loco-regional metastasis, requiring extensive surgery. We describe the clinical presentation, differential diagnosis, both clinical and pathological in terms of other pigmented lesions in the external auditory canal, detailed histopathology, and literature review. Conclusion: We want to emphasize the importance of immediate and adequate biopsy of any pigmented lesion in the head and neck region to rule out MM. Also, we emphasize the importance of deep biopsy for proper histopathological assessment in addition to distinguishing it from benign melanocytic nevi, in order to initiate treatment. PMID- 29594079 TI - Sudden Bilateral Sensorineural Hearing Loss Secondary to Cerebral Venous Thrombosis. AB - Introduction: Sudden sensorineural hearing loss (SSNHL) is an important otological emergency. Up to 90% of the cases are idiopathic. Cerebral venous thrombosis (CVT) is an extremely rare identifiable cause as it only represents 0.5% of all strokes. Case Report: In this paper, an unusual case of bilateral SSNHL secondary to bilateral CVT with rapid and complete recovery is reported. The patient presented with sudden bilateral hearing loss associated with some neurological symptoms. Initial computed tomography (CT) venography revealed a CVT of bilateral transverse sinuses. The patient was started on an anticoagulant and imaging was repeated after five days, revealing the absence of the thrombosis. Serial pure tone audiometry (PTA) showed complete recovery of bilateral hearing within 10 days. Conclusion: Early detection and intervention may fasten hearing recovery and improve the quality of life. The immediate restoration of venous blood flow and intracranial pressure may lead to the complete recovery of bilateral hearing loss. PMID- 29594080 TI - Surgery and Anesthesia Management for Intraoral Synechia: A Case Report. AB - Introduction: Intraoral synechia is a rare congenital condition, generally associated with other maxillo-facial malformations. We present a neonate with congenital intraoral bilateral synechia without any other facial anomalies. Case Report: In this paper, we present a 19-day-old male neonate with congenital intraoral bilateral synechia without any other facial anomalies. We review the literature to discuss the surgical and anesthesia management of this rare congenital disease. Conclusion: The disease manifested with a wide spectrum of symptoms. Most cases need surgery and airway management. In patients with a low risk of bleeding or a compromised airway, it is possible to manage them with face mask-inhalation anesthesia and maintain spontaneous breathing. PMID- 29594081 TI - Case Report of an open Neck Procedure Complication Associated with Laryngeal Mask Airway Use. AB - Introduction: The laryngeal mask airway (LMA) is a safe method to establish airway control during general anaesthesia. In otolaryngology surgery, the use of a LMA is well established in ear surgery; however, the use of a LMA during open neck procedures remains controversial. We report a case in which the pharyngeal distortion by the LMA cuff resulted in an iatrogenic complication. Case Report: A 38-year-old female with a background of multiple myeloma was referred to the otolaryngology team for an open cervical lymph node biopsy. The patient was in remission after a 2 year post chemotherapy treatment, but now presented with a 4 week history of persistent nodal enlargement. During the elective procedure, pharyngeal distortion from the laryngeal airway mask used for airway management resulted in an iatrogenic pharyngeal injury. This case is reported to highlight the importance of communication between the surgeon and anesthetist about the mode of airway management in open neck surgery. Conclusion: Communication between the otolaryngologist and anesthetist is pertinent when selecting the method of airway management in open neck procedures. A LMA should be used with caution during open neck procedures, with the surgeon recognizing the potential for pharyngeal distortion. PMID- 29594082 TI - Vancomycin-Induced Stevens-Johnson Syndrome in a Boy Under 2 Years Old: An Early Diagnosis by Granulysin Rapid Test. AB - Stevens-Johnson syndrome (SJS) is a life-threatening disease, which is mainly ascribed to drugs, such as sulfonamides and psychoepileptics. In this article, we present a pediatric case of vancomycin-induced SJS and an alternative diagnostic algorithm. The patient presented with multiple target-like rashes and vesicles throughout the whole body after receiving vancomycin. Despite the fact that skin biopsy remains the gold standard for diagnosing SJS, the granulysin rapid test by immunochromatographic assay is a non-invasive option for children. In this article, we describe our use of the Algorithm of Drug causality for Epidermal Necrolysis and a modified T-cell activation assay for granzyme B and interferon gamma to screen for the culprit drug. Moreover, we applied the granulysin rapid test as an early diagnosis method for children with drug-induced SJS. PMID- 29594083 TI - Large Parotid Gland Lipoblastoma in a Teenager. AB - Background: Lipoblastomas are rare benign neoplasms that arise from fetal white fat cells. They are typically found in children under the age of 3 and have been reported in the mediastinum, extremities, and infrequently in the head and neck. We present a rare case of a lipoblastoma arising from the parotid gland and the first known report of a parotid lipoblastoma in a teenager. Case presentation: A 15-year-old male presented with a painless, slowly enlarging parotid mass and left facial swelling. A fine needle aspiration was non-diagnostic and initial MRI showed a 3.8 cm * 5.0 cm * 4.0 cm fatty lesion involving the superficial and deep lobes of the left parotid gland and masticator space with widening of the stylo mandibular tunnel and thinning of the adjacent mandibular condyle. The patient was taken to the operating room, and the mass was excised under general anesthesia via a transcervical parotid approach with facial nerve monitoring. The most superficial aspect of the parotid bed was spared and with upper and lower divisions of the facial nerve preserved. The tumor, which primarily involved the deep lobe of the parotid, was entirely excised. Final pathology revealed a 5.2 cm lipoblastoma. The patient did well post-operatively with full function of the facial nerve and 20 months of follow up without evidence of recurrence. Conclusion: This is the first reported case of a lipoblastoma of the parotid gland in a teenager. Although a rare tumor, it should be considered in the differential diagnosis of a parotid mass in this population. PMID- 29594084 TI - Transient Antenatal Bartter's Syndrome: A Case Report. AB - Antenatal Bartter's syndrome is a rare inherited disorder characterized by fetal polyhydramnios and polyuria that is usually detected between 24 and 30 weeks of gestation. However, a rare, severe, but transient form of antenatal Bartter's syndrome due to an x-linked melanoma-associated antigen D2 (MAGED2) mutation has recently been described. This transient type results in the earlier onset of severe polyhydramnios and preterm birth, but spontaneously resolves postnatally. Here, we present a case of a 29-week gestation male born to a mother with severe polyhydramnios, who was subsequently found to have a novel mutation for MAGED2 not previously reported. This is the first and only case not to be treated with indomethacin, yet still resulted in spontaneous resolution of symptoms. Our case suggests the need for awareness of and testing for this new mutation in cases of severe antenatal polyhydramnios and discusses the perinatal treatment of this condition. PMID- 29594085 TI - Stress Signals During Sucking Activity Are Associated With Longer Transition Time to Full Oral Feeding in Premature Infants. AB - Several treatments have been proposed to shorten the time to the attainment of full oral feeding (FOF) for premature infants, but there are only a few evaluation methods useful in estimating predictors of this period. We investigated whether specific items within the disorganized sucking patterns described by the Neonatal Oral-Motor Assessment Scale (NOMAS) could estimate the time to FOF in preterm infants with feeding difficulty. Preterm infants diagnosed with a disorganized sucking pattern in the NOMAS evaluation before 50 weeks of postmenstrual age were included. Video recordings of at least 2 min of oral feeding were further analyzed retrospectively by two assessors and the premature infants who exhibited disorganized sucking patterns (n = 109) were divided into three clusters (clusters 2-4). The observational items compatible with disorganization in the original NOMAS were divided into three groups: cluster 2 (disorganized: arrhythmical), cluster 3 (disorganized: arrhythmical + unable to sustain), and cluster 4 (disorganized: arrhythmical + incoordination +/- unable to sustain) and further divided into incoordination-positive (cluster 4) and incoordination-negative groups (clusters 2 and 3). Premature infants in the incoordination-positive group (cluster 4, which means stress signals) showed a median transition time of 22 days (range: 4-121 days) which was longer than that in the incoordination-negative group (median 6 days; range: 1-25 days). Univariate linear regression analysis revealed that the presence of incoordination among disorganized sucking patterns (NOMAS cluster 4 vs. clusters 2 and 3), birth weight, total parenteral nutrition (TPN) duration, non-invasive positive pressure ventilation duration, the presence of moderate to severe bronchopulmonary dysplasia, pulmonary hypertension, sepsis, small for gestational age (SGA), and necrotizing enterocolitis are associated with the transition time to FOF. In a multivariate linear regression analysis, the variables revealed to be associated with the transition time were TPN duration, SGA, and the presence of stress signals (incoordination-positive group) among disorganized sucking patterns. When selecting premature infants to be treated with swallowing therapy, it is reasonable to pay more attention to the incoordination-positive group described in the NOMAS, that is, premature infants with stress signals to shorten the time to attain FOF. PMID- 29594086 TI - The Megameatus, Intact Prepuce Variant of Hypospadias: Use of the Inframeatal Vascularized Flap for Surgical Correction. AB - Introduction: The megameatus intact prepuce (MIP) variant of hypospadias is a rare variant of hypospadias that is diagnosed either early at the time of circumcision or later as the foreskin is retracted. The true incidence of the anomaly is difficult to determine precisely as some patient never come to medical attention but is felt to under 5% of all cases of hypospadias. The purposes of this study are to review the embryology and clinical findings of MIP and then, in light of a personal experience, present a series of patients evaluated for MIP who were treated with a modification of the Mathieu technique. Materials and methods: A PubMed search of all articles in the MIP variant of hypospadias was carried out followed by an exhaustive review of the literature. The charts of all patients evaluated and treated at Boston Children's Hospital by MC between 2007 and 2017 were reviewed retrospectively. The patients were divided into two groups: those who underwent the standard procedure and those who underwent a repair using a modification of the Mathieu procedure using an inframeatal flap. Results: The embryologic explanation of the MIP variant is not clear but failure of the distal, glanular portion of the urethra to tubularize results in spectrum of abnormality characterized by a deep glanular groove and an abnormal opening of the urethra anywhere from the mid-glans to a subcoronal location. Surgical repair is complicated by a wide distal urethra which may be injured if not properly identified. Overall good outcomes were noted with one patient experiencing a urethra cutaneous fistula in the first group and one patient having a mild glans dehiscence in the second. Conclusion: The MIP variant of hypospadias is a rare variant of hypospadias that presents as a spectrum of urethral anomaly. Surgical repair may not always be necessary but if surgical repair is carried out, the Mathieu technique modification may offer better anatomic delineation of the urethra and will provide an extra layer of tissue to cover the reconstructed urethra. Low complication rates should be expected with adequate functional outcome such as a normal urinary stream. In addition, criteria for selecting patients for surgical repair are provided. PMID- 29594089 TI - The Need for Specialized Pediatric Cardiac Critical Care Training Program in Limited Resource Settings. AB - Congenital heart disease (CHD) is one of the major global health problems with the highest birth prevalence in low- and middle-income countries. In these populous countries, basic health services for the children with CHD, including surgery, are lacking. Even though surgery is performed, outcome after cardiac surgery is influenced by the quality of the postoperative management with a reported high morbidity and mortality. Henceforth, there is an urgent need for comprehensive interventions to provide high quality cardiac intensive care programs to improve the quality of pediatric cardiac surgery services in order to address high morbidity and mortality after cardiac surgery. The development and training of the health workers in the field of pediatric cardiac intensive care program is required. It is imperative to conduct this training prior to actual implementation of the program in limited resources settings. PMID- 29594087 TI - Loop-Mediated Isothermal Amplification Methods for Diagnosis of Bacterial Meningitis. AB - The rapid, accurate, and efficient identification of an infectious disease is critical to ensure timely clinical treatment and prevention in public health settings. In 2015, meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis was responsible for 379,200 (range: 322,700-444,700) deaths. Clinical features alone cannot determine whether bacterial meningitis is present; an analysis of cerebrospinal fluid (CSF) is essential. Loop-mediated isothermal amplification (LAMP) is a nucleic acid amplification method offering an alternative to polymerase chain reaction (PCR). LAMP-based assays for detection of three leading bacteria in CSF for diagnosis of meningitis have been established. The typing assays using LAMP for detection of meningococcal serogroups A, B, C, W, X, and Y as well as H. influenzae serotypes a, b, c, d, e, and f were launched. In comparative analysis of the meningitis pathogen assays, LAMP assays did not yield false negative results, and the detection rate of LAMP assays was superior compared with PCR or conventional culture methods. LAMP assays provide accurate and rapid test results to detect major bacterial meningitis pathogens. Accumulating evidence suggests that LAMP assays have the potential to provide urgently needed diagnostics for bacterial meningitis in resource-limited settings of both developed and developing countries. PMID- 29594088 TI - Nephropathic Cystinosis: Symptoms, Treatment, and Perspectives of a Systemic Disease. AB - Cystinosis is a rare autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene. Main dysfunction is a defective clearance of cystine from lysosomes that leads to accumulation of cystine crystals in every tissue of the body. There are three different forms: infantile nephropathic cystinosis, which is the most common form, juvenile nephropatic, and non-nephropathic cystinosis. Mostly, first symptom in infantile nephropathic cystinosis is renal Fanconi syndrome that occurs within the first year of life. Another prominent symptom is photophobia due to corneal crystal deposition. Cystine depletion therapy with cysteamine delays end-stage renal failure but does not stop progression of the disease. A new cysteamine formulation with delayed-release simplifies the administration schedule but still does not cure cystinosis. Even long-term depletion treatment resulting in bypassing the defective lysosomal transporter cannot reverse Fanconi syndrome. A future perspective offering a curative therapy may be transplantation of CTNS-carrying stem cells that has successfully been performed in mice. PMID- 29594090 TI - Assessing Exposures to Magnetic Resonance Imaging's Complex Mixture of Magnetic Fields for In Vivo, In Vitro, and Epidemiologic Studies of Health Effects for Staff and Patients. AB - A complex mixture of electromagnetic fields is used in magnetic resonance imaging (MRI): static, low-frequency, and radio frequency magnetic fields. Commonly, the static magnetic field ranges from one to three Tesla. The low-frequency field can reach several millitesla and with a time derivative of the order of some Tesla per second. The radiofrequency (RF) field has a magnitude in the microtesla range giving rise to specific absorption rate values of a few Watts per kilogram. Very little attention has been paid to the case where there is a combined exposure to several different fields at the same time. Some studies have shown genotoxic effects in cells after exposure to an MRI scan while others have not demonstrated any effects. A typical MRI exam includes muliple imaging sequences of varying length and intensity, to produce different types of images. Each sequence is designed with a particular purpose in mind, so one sequence can, for example, be optimized for clearly showing fat water contrast, while another is optimized for high-resolution detail. It is of the utmost importance that future experimental studies give a thorough description of the exposure they are using, and not just a statement such as "An ordinary MRI sequence was used." Even if the sequence is specified, it can differ substantially between manufacturers on, e.g., RF pulse height, width, and duty cycle. In the latest SCENIHR opinion, it is stated that there is very little information regarding the health effects of occupational exposure to MRI fields, and long-term prospective or retrospective cohort studies on workers are recommended as a high priority. They also state that MRI is increasingly used in pediatric diagnostic imaging, and a cohort study into the effects of MRI exposure on children is recommended as a high priority. For the exposure assessment in epidemiological studies, there is a clear difference between patients and staff and further work is needed on this. Studies that explore the possible differences between MRI scan sequences and compare them in terms of exposure level are warranted. PMID- 29594092 TI - Herpes Zoster in Persons Living with HIV-1 Infection: Viremia and Immunological Defects Are Strong Risk Factors in the Era of Combination Antiretroviral Therapy. AB - In a cohort of 4,225 persons living with human immunodeficiency virus type 1 (HIV 1) infection (PLWH) enrolled at a southeastern US clinic, the overall rate of incident herpes zoster (HZ) was 101 per 10,000 person-years (PY) between January 1999 and 2017, which nearly quadruples the rate reported for the general US population. In the same cohort, the median age of HZ diagnosis was 39.5 years [interquartile range (IQR) 31.5-49.2] in African American (AA) and 39.1 years (IQR 34.9-45.2) in European American (EA) PLWH, with the highest incidence seen in PLWH who were over 50 years old (144 and 93 per 10,000 PY in AA and EA, respectively, P = 0.18), showing no bias between men (100 per 10,000 PY) and women (101 per 10,000 PY). In multivariable models that were applicable to 245 HZ cases and 3,713 controls, age, nadir CD4+ T-cell (CD4) count, plasma viral load (VL), and duration of combination antiretroviral therapy were independent correlates of incident HZ (adjusted P <= 0.006 for all). Regardless of other factors, viremic PLWH (VL > 50 copies/mL) was at the highest risk of HZ [adjusted odds ratio (OR) > 3.0, P < 0.0001]. PLWH with a nadir CD4 count of >=500 cells/MUL showed a relatively low risk (adjusted OR = 0.48, P = 0.003). By contrast, similar risk estimates were observed with three advancing age groups (30-39, 40-49, and >=50) when compared with age <30 (adjusted OR = 1.86-2.17, P <= 0.010). These findings indicate that efforts for HZ diagnosis and prophylaxis should target viremic PLWH who are over 30 years old and with CD4 count <500 cells/MUL.

AB - Sexually developing adolescents and emerging adults face sexual health risks as well as potentially negative outcomes of online sexual behaviors. The goal of this study was to describe three categories of sexual risk behavior: (1) behavior related to STI/HIV, (2) behavior related to unplanned pregnancy, and (3) online sexual risk behavior. In addition, we investigated whether these behaviors are actually related to negative (health) outcomes. For this purpose, we used data from a Dutch probability survey: "Sex under the age of 25." Adolescents and emerging adults aged 12 through 24 (8,053 boys and 12,447 girls) completed a digital questionnaire, including measures of the risk of STI/HIV and pregnancy, online sexual behavior and non-consensual sex. Chi-square tests and logistic regressions were used to test for gender and age differences and compute associations between risk behavior and negative outcomes. The results showed that the risk of unplanned pregnancy is low in the Netherlands. It seems that adolescents and emerging adults are less aware of the risk of STI/HIV than of the risk of pregnancy. About 11% of the participants had had more than one partner in the last 6 months and had not used condoms consistently with their last partner, and these participants had a 3.56 times higher likelihood of ever being diagnosed with an STI. Although many young people stop using condoms with their partner after a while, most of them did not get tested for STIs. More emerging adults (aged 18-24) engage in sexting (sending personal nude pictures and sex videos to others), but the chance that these images are shared with other people than the intended recipient is higher among adolescents (aged 12-17). The results of this study can guide professionals working in sex education and sexual health services to focus their efforts on the risk behaviors in the Netherlands that deserve most attention. PMID- 29594091 TI - Big Data's Role in Precision Public Health. AB - Precision public health is an emerging practice to more granularly predict and understand public health risks and customize treatments for more specific and homogeneous subpopulations, often using new data, technologies, and methods. Big data is one element that has consistently helped to achieve these goals, through its ability to deliver to practitioners a volume and variety of structured or unstructured data not previously possible. Big data has enabled more widespread and specific research and trials of stratifying and segmenting populations at risk for a variety of health problems. Examples of success using big data are surveyed in surveillance and signal detection, predicting future risk, targeted interventions, and understanding disease. Using novel big data or big data approaches has risks that remain to be resolved. The continued growth in volume and variety of available data, decreased costs of data capture, and emerging computational methods mean big data success will likely be a required pillar of precision public health into the future. This review article aims to identify the precision public health use cases where big data has added value, identify classes of value that big data may bring, and outline the risks inherent in using big data in precision public health efforts. PMID- 29594094 TI - Navigating Multiple Sources of Healing in the Context of HIV/AIDS and Wide Availability of Antiretroviral Treatment: A Qualitative Study of Community Participants' Perceptions and Experiences in Rural South Africa. AB - Background: South Africa introduced the world's largest antiretroviral treatment (ART) program in 2004 and since 2016 the Department of Health implemented a universal Treatment as Prevention (TasP) strategy. However, some studies have shown that increasing the availability of ART is insufficient for the comprehensive treatment of HIV, since many people still use traditional health practitioners (THPs) to avoid being identified as HIV positive, and for reasons unrelated to HIV/AIDS. This qualitative study explored the factors influencing how both HIV-negative and HIV-positive people choose amongst multiple sources of healing and how they engage with them, in the context of HIV/AIDS and wide availability of ART. Methods: Data were collected as part of a larger TasP trial at the Africa Health Research Institute, KwaZulu-Natal. Repeat in-depth individual interviews were conducted with 10 participants. Repeat group discussions were conducted with 42 participants. Group discussion data were triangulated using community walks and photo-voice techniques to give more insight into the perceptions of community members. All data were collected over 18 months. Thematic analysis was used to analyze participants' narratives from both individual interviews and group discussions. Findings: In the context of HIV/AIDS and wide availability of ART, use of biomedical and traditional healing systems seemed to be common in this locality. People used THPs to meet family expectations, particularly those of authoritative heads of households such as parents or grandparents. Most participants believed that THPs could address specific types of illnesses, especially those understood to be spiritually caused and which could not be addressed or cured by biomedical practitioners. However, it was not easy for participants to separate some spiritually caused illnesses from biological illnesses in the context of HIV/AIDS. These data demonstrate that in this context, the use of THPs continues regardless of the wide availability of ART. To meet the health care needs of those patients requiring a health care system which combines biomedical and traditional approaches, collaboration and integration of biomedical and traditional health care should be considered. PMID- 29594095 TI - One Health-ness Evaluation of Cysticercosis Surveillance Design in Portugal. AB - The increasing occurrence of human cysticercosis, a zoonotic neglected disease, is challenging the traditional prevention and control paradigm and calling for One Health (OH) solutions in industrialized countries. OH solutions for health interventions are increasingly being used to capture expected and unexpected outcomes across people, animals, and the environment. The Network for Evaluation of One Health (NEOH) proposes an evidence-based framework, relying on systems and mixed methods approaches to evaluate the One Health-ness. In this case study, this tool is used to evaluate the design of the Observatory of Taeniasis and Cysticercosis, as an example of intersectorial collaboration for surveillance in Portugal. The OH Initiative (drivers and expected outcomes) and its system (boundaries, aim, dimensions, actors, and stakeholders) were described. The different aspects of this Initiative were scored with values from 0 (=no OH approach) to 1 (=perfect OH approach). The OH index was 0.31. Its OH ratio is 1.98. Overall scores were as follows: OH thinking 0.75; OH planning 0.60; OH working 0.60; OH sharing 0.35; OH learning 0.50; and systemic organization 0.50. Operational levels of the Initiative are the main strengths, indicating a comprehensive multidimensional innovative approach and transdisciplinarity. Critical issues in the supporting infrastructure were observed, related to communication, learning and organizational gaps in the project, with the evaluation being conducted as the project is being designed and implemented. The strengths and weaknesses detected may be used to refine the Initiative. This case study therefore exemplifies and supports OH assessment also for ongoing projects, at design and early implementation stages for guiding and guaranteeing an OH oriented perspective.

AB - Background: In Papua New Guinea (PNG), a malaria treatment policy using rapid diagnostic tests (RDTs) plus artemisinin-based combination therapy (ACT) was widely introduced to rural communities in 2012. The objectives of the study were to evaluate the effect of this RDT/ACT introduction to a rural PNG population on health service utilization and to compare factors associated with health service utilization before and after the RDT/ACT introduction. Methods: Household surveys with structured questionnaires were conducted before and after the introduction of RDT/ACT in a catchment area of a health center in East Sepik Province, PNG. We interviewed caregivers with children less than 15 years of age and collected data on fever episodes in the preceding 2 weeks. Using propensity score matching, febrile children before the introduction of RDT/ACT were matched to febrile children after the introduction. Then, the adjusted difference in the proportion of health service utilization [i.e., the average treatment effect (ATE) of the introduction of RDT/ACT on health service utilization] was estimated. We also employed a multilevel Poisson regression model to investigate factors influencing the use of health services. Results: Of 4,690 children, 911 (19%) were reported to have a fever episode. The unadjusted proportion of health service utilization was 51.7 and 57.2% before and after the RDT/ACT introduction, respectively. After matching, no significant difference in the health service utilization was observed before and after the introduction of RDT/ACT (ATE: 0.063, 95% confidence interval -0.024 to 0.150). Multilevel regression analysis showed that the consistent factors associated with a higher utilization of health services were severe illness and being female. Conclusion: The utilization of health services was not significantly different before and after the introduction of RDT/ACT. Villagers may have neither sufficient informations on the new protocol nor high acceptance of RDT/ACT. The observed gender bias in health service utilization could be due to female caregivers' preferences toward girls. PMID- 29594097 TI - Designing Superoxide-Generating Quantum Dots for Selective Light-Activated Nanotherapy. AB - The rapid emergence of superbugs, or multi-drug resistant (MDR) organisms, has prompted a search for novel antibiotics, beyond traditional small-molecule therapies. Nanotherapeutics are being investigated as alternatives, and recently superoxide-generating quantum dots (QDs) have been shown as important candidates for selective light-activated therapy, while also potentiating existing antibiotics against MDR superbugs. Their therapeutic action is selective, can be tailored by simply changing their quantum-confined conduction-valence band (CB VB) positions and alignment with different redox half-reactions-and hence their ability to generate specific radical species in biological media. Here, we show the design of superoxide-generating QDs using optimal QD material and size well matched to superoxide redox potential, charged ligands to modulate their uptake in cells and selective redox interventions, and core/shell structures to improve their stability for therapeutic action. We show that cadmium telluride (CdTe) QDs with conduction band (CB) position at -0.5 V with respect to Normal Hydrogen Electron (NHE) and visible 2.4 eV bandgap generate a large flux of selective superoxide radicals, thereby demonstrating the effective light-activated therapy. Although the positively charged QDs demonstrate large cellular uptake, they bind indiscriminately to cell surfaces and cause non-selective cell death, while negatively charged and zwitterionic QD ligands reduce the uptake and allow selective therapeutic action via interaction with redox species. The stability of designed QDs in biologically-relevant media increases with the formation of core shell QD structures, but an appropriate design of core-shell structures is needed to minimize any reduction in charge injection efficiency to adsorbed oxygen molecules (to form superoxide) and maintain similar quantitative generation of tailored redox species, as measured using electron paramagnetic resonance (EPR) spectroscopy and electrochemical impedance spectroscopy (EIS). Using these findings, we demonstrate the rational design of QDs as selective therapeutic to kill more than 99% of a priority class I pathogen, thus providing an effective therapy against MDR superbugs. PMID- 29594098 TI - High-Power-Density, High-Energy-Density Fluorinated Graphene for Primary Lithium Batteries. AB - Li/CFx is one of the highest-energy-density primary batteries; however, poor rate capability hinders its practical applications in high-power devices. Here we report a preparation of fluorinated graphene (GFx) with superior performance through a direct gas fluorination method. We find that the so-called "semi-ionic" C-F bond content in all C-F bonds presents a more critical impact on rate performance of the GFx in comparison with sp2 C content in the GFx, morphology, structure, and specific surface area of the materials. The rate capability remains excellent before the semi-ionic C-F bond proportion in the GFx decreases. Thus, by optimizing semi-ionic C-F content in our GFx, we obtain the optimal x of 0.8, with which the GF0.8 exhibits a very high energy density of 1,073 Wh kg-1 and an excellent power density of 21,460 W kg-1 at a high current density of 10 A g-1. More importantly, our approach opens a new avenue to obtain fluorinated carbon with high energy densities without compromising high power densities. PMID- 29594099 TI - Anthocyanin Biosynthesis and Degradation Mechanisms in Solanaceous Vegetables: A Review. AB - Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom. In plants, anthocyanins play a role not only in reproduction, by attracting pollinators and seed dispersers, but also in protection against various abiotic and biotic stresses. There is accumulating evidence that anthocyanins have health-promoting properties, which makes anthocyanin metabolism an interesting target for breeders and researchers. In this review, the state of the art knowledge concerning anthocyanins in the Solanaceous vegetables, i.e., pepper, tomato, eggplant, and potato, is discussed, including biochemistry and biological function of anthocyanins, as well as their genetic and environmental regulation. Anthocyanin accumulation is determined by the balance between biosynthesis and degradation. Although the anthocyanin biosynthetic pathway has been well-studied in Solanaceous vegetables, more research is needed on the inhibition of biosynthesis and, in particular, the anthocyanin degradation mechanisms if we want to control anthocyanin content of Solanaceous vegetables. In addition, anthocyanin metabolism is distinctly affected by environmental conditions, but the molecular regulation of these effects is poorly understood. Existing knowledge is summarized and current gaps in our understanding are highlighted and discussed, to create opportunities for the development of anthocyanin-rich crops through breeding and environmental management. PMID- 29594100 TI - Ursolic Acid Hydrazide Based Organometallic Complexes: Synthesis, Characterization, Antibacterial, Antioxidant, and Docking Studies. AB - In thecurrent research work,eleven metal complexes were synthesized from the hydrazide derivative of ursolic acid. Metal complexes of tin, antimony and iron were synthesized and characterized by FT-IR and NMR spectroscopy. The antibacterial and antioxidant activities were performed for these complexes, which revealed that the metal complexes synthesized are more potent than their parent compounds. We observed that antioxidant activity showed by triphenyltin complex was significant and least activity have been shown by antimony trichloride complex. The synthesized metal complexes were then evaluated against two Gram-negative and two Gram-positive bacterial strains. Triphenyl tin complex emerged as potent antibacterial agent with MIC value of 8 MUg/ml each against Shigellaspp, Salmonella typhi and Staphylococcus aureus. While, the MIC value against Streptococcus pneumoniae is 4 MUg/ml. Computational docking studies were carried out on molecular targets to interpret the results of antioxidant and antibacterial activities. Based on the results, it may be inferred that the metal complexes of ursolic acid are more active as compared to the parent drug and may be proved for some other pharmacological potential by further analysis. PMID- 29594102 TI - Facile Fabrication of BiOI/BiOCl Immobilized Films With Improved Visible Light Photocatalytic Performance. AB - HIGHLIGHTS A facial method was used to fabricate BiOI/BiOCl film at room temperature.30% BiOI/BiOCl showed an excellent photocatalytic activity and stability.Improvement of photocatalytic activity was owed to expanded visible light absorption and high separation efficiency of charge. Photocatalysis has been considered to be one of the most promising ways to photodegrade organic pollutants. Herein, a series of BiOI/BiOCl films coating on FTO were fabricated through a simple method at room temperature. The photocatalytic efficiency of 30%BiOI/BiOCl could reach more than 99% aiming to degrading RhB and MB after 90 and 120 min, respectively. Compared with BiOCl, 30%BiOI/BiOCl showed 12 times higher efficiency when degrading RhB. In comparison with BiOI, 30%BiOI/BiOCl showed 5 and 6 times higher efficiency when degrading RhB and MB, respectively. These obvious enhancements were attributed to expanded visible light absorption and high separation performance of photoinduced charge. Moreover, the photocatalytic activity of 30%BiOI/BiOCl had no obvious decrease after five recycles, suggesting that it was a promising photocatalyst for the removal of MB and RhB pollutants. Finally, the possible growth process for the BiOI/BiOCl thin films and photocatalysis mechanism were investigated in details. This work would provide insight to the reasonable construction of BiOX heterojunction and the photocatalytic mechanism in degrading organic pollutants.

Pathogenetic aspects of this autoimmune disorder may elucidate their possible connection. Two exemplificative cases are taken as a pretext for a short review of this topic. PMID- 29594101 TI - Computer-Aided Drug Design in Epigenetics. AB - Epigenetic dysfunction has been widely implicated in several diseases especially cancers thus highlights the therapeutic potential for chemical interventions in this field. With rapid development of computational methodologies and high performance computational resources, computer-aided drug design has emerged as a promising strategy to speed up epigenetic drug discovery. Herein, we make a brief overview of major computational methods reported in the literature including druggability prediction, virtual screening, homology modeling, scaffold hopping, pharmacophore modeling, molecular dynamics simulations, quantum chemistry calculation, and 3D quantitative structure activity relationship that have been successfully applied in the design and discovery of epi-drugs and epi-probes. Finally, we discuss about major limitations of current virtual drug design strategies in epigenetics drug discovery and future directions in this field. PMID- 29594103 TI - Chloride Ion Transport by the E. coli CLC Cl-/H+ Antiporter: A Combined Quantum Mechanical and Molecular-Mechanical Study. AB - We performed steered molecular dynamics (SMD) and umbrella sampling simulations of Cl- ion migration through the transmembrane domain of a prototypical E. coli CLC Cl-/H+ antiporter by employing combined quantum-mechanical (QM) and molecular mechanical (MM) calculations. The SMD simulations revealed interesting conformational changes of the protein. While no large-amplitude motions of the protein were observed during pore opening, the side chain rotation of the protonated external gating residue Glu148 was found to be critical for full access of the channel entrance by Cl-. Moving the anion into the external binding site (Sext) induced small-amplitude shifting of the protein backbone at the N terminal end of helix F. As Cl- traveled through the pore, rigid-body swinging motions of helix R separated it from helix D. Helix R returned to its original position once Cl- exited the channel. Population analysis based on polarized wavefunction from QM/MM calculations discovered significant (up to 20%) charge loss for Cl- along the ion translocation pathway inside the pore. The delocalized charge was redistributed onto the pore residues, especially the functional groups containing pi bonds (e.g., the Tyr445 side chain), while the charges of the H atoms coordinating Cl- changed almost negligibly. Potentials of mean force computed from umbrella sampling at the QM/MM and MM levels both displayed barriers at the same locations near the pore entrance and exit. However, the QM/MM PMF showed higher barriers (~10 kcal/mol) than the MM PMF (~2 kcal/mol). Binding energy calculations indicated that the interactions between Cl- and certain pore residues were overestimated by the semi-empirical PM3 Hamiltonian and underestimated by the CHARMM36 force fields, both of which were employed in the umbrella sampling simulations. In particular, CHARMM36 underestimated binding interactions for the functional groups containing pi bonds, missing the stabilizations of the Cl- ion due to electron delocalization. The results suggested that it is important to explore these quantum effects for accurate descriptions of the Cl- transport.

AB - Background: Immunonutrition (IN) significantly reduces the incidence of postoperative infectious complications and the length of hospitalization in patients undergoing major elective surgery for gastrointestinal malignances. However, the clinical benefit of IN in patients who have undergone esophagectomy for esophageal cancer is unclear. Moreover, the effect of enteral IN in patients during preoperative adjuvant chemoradiotherapy and in patients treated with concurrent chemoradiotherapy for advanced esophageal cancer is unknown. Summary: This review analyzes the evidence supporting the enteral administration of IN in patients who have undergone esophagectomy and/or chemoradiotherapy for esophageal cancer. Twelve trials that evaluated IN exclusively in patients who underwent esophagectomy were published between January 1980 and August 2017. Two trials concerning IN during chemoradiotherapy for esophageal cancer were identified in the same period. However, the evidence is insufficient to recommend enteral IN in patients who have undergone esophagectomy and/or chemoradiotherapy for esophageal cancer. Key Message: Further evidence from well-designed randomized controlled trials is required to verify the clinical benefits of enteral IN in patients undergoing esophagectomy and/or chemoradiotherapy for esophageal cancer. Practical Implications: Resolvins, which are generated from EPA, are novel anti inflammatory lipid mediators and may play a key role in the resolution of acute inflammation when IN is supplemented with EPA in patients undergoing severely stressful operations. PMID- 29594108 TI - Short-Term Outcomes of Extended Pancreatectomy: A Single-Surgeon Experience. AB - Background/Aims: The International Study Group of Pancreatic Surgery recently published a consensus statement on the definition of extended pancreatectomy (EP). We aimed to determine the safety profile and short-term outcomes of EP compared to standard pancreatectomy (SP). To mitigate surgeon bias, only pancreatectomies performed by a single surgeon were included. Methods: Ninety consecutive patients who underwent pancreatectomy by a single surgeon over a period of 5 years and who met our study criteria were classified into an SP or an EP group. Sixty-two patients underwent pancreaticoduodenectomy (PD), including total pancreatectomy, and 28 patients underwent distal pancreatectomy. Results: The 25 patients who underwent EP had significantly increased operation time, estimated blood loss, postoperative intensive care unit (ICU) transfer, and postoperative stay compared to the 65 patients who underwent SP. There was 1 (1.1%) 30-day mortality and 4 (4.4%) in-hospital mortalities. Postoperative morbidity and mortality were similar between both groups. Subgroup analysis of the patients who underwent PD demonstrated that the EP group (n = 22) had significantly increased operation time and postoperative ICU transfers. Conclusion: Although patients who underwent EP experienced significantly increased operative time, blood loss, and postoperative stay, they did not experience significantly higher postoperative morbidity or mortality compared to patients who underwent SP. PMID- 29594109 TI - Impact of Three-Dimensional Surgical Simulation on Pancreatic Surgery. AB - Background/Aims: Anatomical variations are frequently encountered during hepato biliary-pancreatic surgeries, requiring surgeons to have a precise understanding of the surgical anatomy in order to perform a safe surgery. We evaluated the impact of novel three-dimensional (3D) surgical simulation on pancreatic surgeries to enhance surgical residents' understanding. Methodology: Between January 2013 and May 2014, 61 preoperative 3D surgical simulations were performed. The consistency (0-10, with 10 representing 100% consistency) among the 15 surgical residents' anatomical drawings from multidetector computed tomography images and the simulated 3D images by SYNAPSE VINCENT(r) was assessed. We divided the surgical residents into two groups - first- to fifth-year postgraduate doctors (group A) and sixth- to tenth-year postgraduate doctors (group B) - and compared the self-assessment scores between these two groups. Results: In terms of the self-assessment scores, a statistically significant difference was observed between the two groups (p < 0.001). Conclusions: In this study, 3D surgical simulation was useful for preoperative assessments prior to pancreatic surgery, especially in younger postgraduate surgeons. PMID- 29594110 TI - Is Colonoscopy Indicated in Young Patients with Hematochezia. AB - Background/Aims: While colonoscopy is indicated in patients >50 years old presenting with hematochezia, its role in those <=50 remains debatable. This study aims to evaluate the role of colonoscopy in patients presenting with hematochezia who are <=50 years old. Methods: A retrospective review of all patients aged <=50 years who underwent colonoscopy for hematochezia in 2012 was conducted. Patient demographics, endoscopic details, and histological results were analyzed. Patients were stratified by age to compare differences in outcome. Results: A total of 361 patients with a median age of 44 (range, 18-50) years were reviewed. Hemorrhoid (n = 183, 69.6%) was the most common etiology. Seventy two neoplastic polyps were identified in 48 (13.3%) patients. There was a significantly larger proportion of patients aged 41-50 years who had neoplastic polyps compared to those aged <=40 (18.8 vs. 3.8%, p <= 0.001); 43.8% (n = 28) of the neoplastic polyps found in those aged 41-50 were proximal to the splenic flexure. The only 2 (0.5%) patients with malignancy were aged 41-50 years. Conclusion: Performing colonoscopy in patients presenting with hematochezia should be strongly considered for those aged 41-50 years in view of the significant likelihood of underlying neoplastic polyps compared to those aged <=40 years. PMID- 29594111 TI - Waiting Time following Neoadjuvant Chemoradiotherapy for Rectal Cancer: Does It Really Matter. AB - Background: Neoadjuvant chemoradiotherapy (CRT) is considered the standard approach before any surgical intervention for locally advanced rectal tumors and has been proven to significantly improve the local recurrence rates of rectal cancer. However, the optimal timing of surgical resection after neoadjuvant CRT remains debatable. Objective and Methods: We conducted a retrospective review of 65 consecutive patients with locally advanced rectal cancer who underwent preoperative CRT followed by surgical resection in order to evaluate the optimal time for surgical treatment. We used two alternative groups for analysis: patients who underwent surgery up to 6 weeks after CRT (n = 28) and those who underwent surgery 6 weeks or more after CRT (n = 27). Also, we compared patients who were operated on within 3 months (n = 39) with those who underwent surgical resection after more than 3 months (n = 16). Nonresponders to CRT were excluded from the analysis. Results: There was no statistically significant association between waiting period post CRT and radiological downstaging for any group (p > 0.05 for any association). Also, there was no association between recurrence of disease, cancer-related deaths, perineural invasion, or positive lymph node ratio and any waiting period up to 3 months (p > 0.05 for all associations). Conclusion: In this small exploratory study there was no evident difference in outcome according to timing of surgery, which suggests that further research in larger cohorts is warranted.

PMID- 29594113 TI - Interplay of Inflammatory Mediators with Epigenetics and Cartilage Modifications in Osteoarthritis. AB - Osteoarthritis (OA), a degenerative disease of diarthrodial joints, is influenced by mechanical and inflammatory factors with aging, obesity, chronic injuries, and secondary diseases thought to be major factors driving the process of articular cartilage degeneration. Chondrocytes, the cellular component of cartilage, reside in an avascular environment and normally have limited potential to replicate. However, extrinsic factors such as injury to the joint or intrinsic alterations to the chondrocytes themselves can lead to an altered phenotype and development of OA. Synovial inflammation is also a pivotal element of the osteoarthritic, degenerative process: influx of pro-inflammatory cytokines and production of matrix metalloproteinases accelerate advanced cellular processes such as synovitis and cartilage damage. As well as a genetic input, recent data have highlighted epigenetic factors as contributing to disease. Studies conducted over the last decade have focused on three key aspects in OA; inflammation and the immune response, genome-wide association studies that have identified important genes undergoing epigenetic modifications, and finally how chondrocytes transform in their function during development and disease. Data highlighted here have identified critical inflammatory genes involved in OA and how these factors impact chondrocyte hypertrophy in the disease. This review also addresses key inflammatory factors in synovial inflammation, epigenetics, and chondrocyte fate, and how agents that inhibit epigenetic mechanisms like DNA methylation and histone modifications could aid in development of long-term treatment strategies for the disease. PMID- 29594115 TI - Optimum Use of Acute Treatments for Hereditary Angioedema: Evidence-Based Expert Consensus. AB - Acute treatment of hereditary angioedema due to C1 inhibitor deficiency has become available in the last 10 years and has greatly improved patients' quality of life. Two plasma-derived C1 inhibitors (Berinert and Cinryze), a recombinant C1 inhibitor (Ruconest/Conestat alpha), a kallikrein inhibitor (Ecallantide), and a bradykinin B2 receptor inhibitor (Icatibant) are all effective. Durably good response is maintained over repeated treatments and several years. All currently available prophylactic agents are associated with breakthrough attacks, therefore an acute treatment plan is essential for every patient. Experience has shown that higher doses of C1 inhibitor than previously recommended may be desirable, although only recombinant C1 inhibitor has been subject to full dose-response evaluation. Treatment of early symptoms of an attack, with any licensed therapy, results in milder symptoms, more rapid resolution and shorter duration of attack, compared with later treatment. All therapies have been shown to be well tolerated, with low risk of serious adverse events. Plasma-derived C1 inhibitors have a reassuring safety record regarding lack of transmission of virus or other infection. Thrombosis has been reported in association with plasma-derived C1 inhibitor in some case series. Ruconest was associated with anaphylaxis in a single rabbit-allergic volunteer, but no further anaphylaxis has been reported in those not allergic to rabbits despite, in a few cases, prior IgE sensitization to rabbit or milk protein. Icatibant is associated with high incidence of local reactions but not with systemic effects. Ecallantide may cause anaphylactoid reactions and is given under supervision. For children and pregnant women, plasma derived C1 inhibitor has the best evidence of safety and currently remains first line treatment. PMID- 29594114 TI - Microenvironment-Cell Nucleus Relationship in the Context of Oxidative Stress. AB - The microenvironment is a source of reactive oxygen species (ROS) that influence cell phenotype and tissue homeostasis. The impact of ROS on redox pathways as well as directly on epigenetic mechanisms and the DNA illustrate communication with the cell nucleus. Changes in gene transcription related to redox conditions also influence the content and structure of the extracellular matrix. However, the importance of microenvironmental ROS for normal progression through life and disease development still needs to be thoroughly understood. We illustrate how different ROS concentration levels trigger various intracellular pathways linked to nuclear functions and determine processes necessary for the differentiation of stem cells. The abnormal predominance of ROS that leads to oxidative stress is emphasized in light of its impact on aging and diseases related to aging. These phenomena are discussed in the context of the possible contribution of extracellular ROS via direct diffusion into cells responsible for organ function, but also via an impact on stromal cells that triggers extracellular modifications and influences mechanotransduction. Finally, we argue that organs-on-a-chip with controlled microenvironmental conditions can help thoroughly grasp whether ROS production is readily a cause or a consequence of certain disorders, and better understand the concentration levels of extracellular ROS that are necessary to induce a switch in phenotype.

Recent evidences implicate the virus as an emergent neuropathological agent promoting serious pathologies of the human nervous system, that include destructive and malformation consequences such as development of ocular and fetal brain lesions, microcephaly in neonates, and Guillain-Barre syndrome (GBS) in adults. These neurological disorders of both central and peripheral nervous systems are thought to be associated to the neurotropic properties of the virus that has ability to infect neural stem cells as well as peripheral neurons, a hallmark of its pathogenicity. The presence of autoantibodies against gangliosides plays a pivotal role in the etiogenesis of GBS and a variety of neurological disorders. Gangliosides are a class of galactose-containing cerebrosides mainly expressed in nervous system tissues playing a critical role in the physiology of neural cells and neurogenesis. Herein, our findings indicate that patients at acute phase of ZIKV infection without any neurological signs show increased levels of IgG autoantibody against GD3 gangliosides, a class of glycolipid found to be highly expressed in neural stem cell acting in the maintenance of their self-renewal cellular capacity. It is possible that a pathological threshold of these antibodies is only acquired in secondary or subsequent infections. In the light of these evidences, we propose that the target of GD3 by autoimmune responses may possibly has an effect in the neuropathy and neurogenesis disorder seen during ZIKV infection. PMID- 29594117 TI - Erythrocyte Salt Sedimentation Assay Does Not Predict Response to Renal Denervation. AB - Renal denervation (RDN) has recently been shown to be effective in patients without antihypertensive medication. However, about 30% of patients do not respond to RDN, and therefore, there exists a need to find predictors of response. Individuals are either salt-sensitive (SS) or non-salt-sensitive (NSS) in terms of their blood pressure (BP) regulation. The sympathetic nervous system can influence water and salt handling. RDN reduces sympathetic drive and has an impact on salt excretion. The present study was conducted to test the influence of salt sensitivity in terms of the BP reducing effect after RDN procedure. Salt sensitivity was estimated using the in vitro Erythrocyte Salt Sedimentation Assay (ESS). In 88 patients with resistant hypertension, RDN was performed. Office BP and lab testing were performed at baseline and at month 1, 3, 6, 12, 18, and 24 after RDN. A responder rate of 64.7% has been observed. Salt sensitivity measurements (ESS-Test) were completed in a subgroup of 37 patients with resistant hypertension. In this group, 15 were SS and 17 were salt-resistant according to the in vitro assay, respectively. The responder rate was 60% in SS patients and 59.1% in NSS patients, respectively. Electrolytes as well as aldosterone and renin levels did not differ between the two groups at baseline and in the follow-up measurements. The present study showed that salt sensitivity, estimated using the ESS in vitro test, did not affect the outcome of RDN and, therefore, does not help to identify patients suitable for RDN. PMID- 29594118 TI - The Many Faces of Primary Aldosteronism and Cushing Syndrome: A Reflection of Adrenocortical Tumor Heterogeneity. AB - Adrenal cortical tumors constitute a heterogeneous group of neoplasms with distinct clinical, morphological, and molecular features. Recent discoveries of specific genotype-phenotype correlations in adrenal cortical adenomas have transformed our understanding of their respective endocrine syndromes. Indeed, a proportion of patients with primary aldosteronism are now known to harbor adrenal cortical adenomas with heterogeneous molecular alterations (KCNJ5, ATP1A1, ATP2B3, and CACNA1D) involving the calcium/calmodulin kinase signaling pathway. Several lines of evidence suggest that KCNJ5-mutant aldosterone-producing adenomas have distinct clinicopathological phenotype compared to those harboring ATP1A1, ATP2B3, and CACNA1D mutations. Benign adrenal cortical tumors presenting with Cushing syndrome often have diverse mutations (PRKACA, PRKAR1A, GNAS, PDE11A, and PDE8B) involving the cyclic AMP signaling pathway. In addition to cortisol-producing adenomas, bilateral micronodular adrenocortical disease and primary bilateral macronodular adrenal hyperplasia (PBMAH) have also expanded the spectrum of benign neoplasms causing adrenal Cushing disease. The recent discovery of inactivating ARMC5 germline mutations in PBMAH has challenged the old belief that this disorder is mainly a sporadic disease. Emerging evidence suggests that PBMAH harbors multiple distinct clonal proliferations, reflecting the heterogeneous genomic landscape of this disease. Although most solitary adrenal cortical tumors are sporadic, there is an increasing recognition that inherited susceptibility syndromes may also play a role in their pathogenesis. This review highlights the molecular and morphological heterogeneity of benign adrenal cortical neoplasms, reflected in the diverse presentations of primary aldosteronism and adrenal Cushing syndrome. PMID- 29594120 TI - The Safety and Efficacy of the Continuous Peripheral Nerve Block in Postoperative Analgesia of Pediatric Patients. AB - Postoperative analgesia is imperative in the youngest patients. Pain, especially if experienced during childhood, has numerous adverse effects-from psychological, through complications of the underlying disease (prolonged treatment, hospital stay, and increased costs of the treatment) to an increase in the incidence of death due to the onset of the systemic inflammatory response. Peripheral blocks provide analgesia for 12-16 h, and are safer due to rare side effects that are easier to treat. The continuous peripheral block (CPNB) has been increasingly used in recent years for complete and prolonged analgesia of pediatric patients, as well as a part of multidisciplinary treatment of complex regional pain syndrome. It has been shown that outpatient CPNB reduces the need for parenteral administration of opioid analgetics. It has also been proved that this technique can be used in pediatric patients in home conditions. Safety of CPNB is based on the increasing use of ultrasound as well as on the introduction of single enantiomers local anesthetics (ropivacaine and levobupivacaine) in lower concentrations. It is possible to discharge patient home with catheter, but it is necessary to provide adequate education for staff, patients, and parents, as well as to have dedicated anesthesiology team. Postoperative period without major pain raises the morale of the child, parents. and medical staff. PMID- 29594119 TI - Monogenic Causes of Proteinuria in Children. AB - Glomerular disease is a common cause for proteinuria and chronic kidney disease leading to end-stage renal disease requiring dialysis or kidney transplantation in children. Nephrotic syndrome in children is diagnosed by the presence of a triad of proteinuria, hypoalbuminemia, and edema. Minimal change disease is the most common histopathological finding in children and adolescents with nephrotic syndrome. Focal segmental sclerosis is also found in children and is the most common pathological finding in patients with monogenic causes of nephrotic syndrome. Current classification system for nephrotic syndrome is based on response to steroid therapy as a majority of patients develop steroid sensitive nephrotic syndrome regardless of histopathological diagnosis or the presence of genetic mutations. Recent studies investigating the genetics of nephrotic syndrome have shed light on the pathophysiology and mechanisms of proteinuria in nephrotic syndrome. Gene mutations have been identified in several subcellular compartments of the glomerular podocyte and play a critical role in mitochondrial function, actin cytoskeleton dynamics, cell-matrix interactions, slit diaphragm, and podocyte integrity. A subset of genetic mutations are known to cause nephrotic syndrome that is responsive to immunosuppressive therapy but clinical data are limited with respect to renal prognosis and disease progression in a majority of patients. To date, more than 50 genes have been identified as causative factors in nephrotic syndrome in children and adults. As genetic testing becomes more prevalent and affordable, we expect rapid advances in our understanding of mechanisms of proteinuria and genetic diagnosis will help direct future therapy for individual patients. PMID- 29594121 TI - Echinococcus granulosus: Cure for Cancer Revisited. AB - Whereas a number of parasites are well recognized risk factors for a number of different cancers in mammalian hosts, there is limited information on the ability of parasitic organisms to induce anticancer effects. There are conflicting reports that echinococcosis, caused by the canine tapeworm Echinococcus granulosus, can decrease or increase cancer risk. This review considers both indirect anticancer effects as the result of adaptive immunity generated against certain echinococcal antigens and the direct effect of molecules released by E. granulosus whose activity directly inhibits cancer cell migration and growth. In conclusion, E. granulosus probably secretes molecules that can be developed as anticancer therapeutics in future. PMID- 29594123 TI - Getting Digital Assets from Public-Private Partnership Research Projects through "The Valley of Death," and Making Them Sustainable. AB - Projects in public-private partnerships, such as the Innovative Medicines Initiative (IMI), produce data services and platforms (digital assets) to help support the use of medical research data and IT tools. Maintaining these assets beyond the funding period of a project can be a challenge. The reason for that is the need to develop a business model that integrates the perspectives of all different stakeholders involved in the project, and these digital assets might not necessarily be addressing a problem for which there is an addressable market of paying customers. In this manuscript, we review four IMI projects and the digital assets they produced as a means of illustrating the challenges in making digital assets sustainable and the lessons learned. To progress digital assets beyond proof-of-concept into widely adopted tools, there is a need for continuation of multi-stakeholder support tailored to these assets. This would be best done by implementing a structure similar to the accelerators that are in place to help transform startup businesses into growing and thriving businesses. The aim of this article is to highlight the risk of digital asset loss and to provoke discussion on the concept of developing an "accelerator" for digital assets from public-private partnership research projects to increase the chance that digital assets will be sustained and continue to add value long after a project has ended. PMID- 29594124 TI - Precision Medicine and Global Health: The Good, the Bad, and the Ugly. PMID- 29594122 TI - Comorbidities in Spondyloarthritis. AB - Comorbidities in spondyloarthritis (SpA) add to the burden of disease by contributing to disease activity, functional and work disability, and mortality. Thus, awareness of comorbidities in SpA is crucial to improve their screening and management and to ultimately improve outcomes in those affected. Osteoporosis has been reported to be the most prevalent comorbidity in SpA, and its risk is increased in these patients, compared with the general population; the risk of vertebral fractures requires further evaluation. Cardiovascular risk is also increased in this population, both due to an increase of the traditional cardiovascular risk factors in these patients, but also due to the presence of inflammation. The role of non-steroidal anti-inflammatory drugs in this increased risk needs further elucidation, but there is consensus on the need to encourage smoking cessation and to perform periodic evaluation of cardiovascular risk in these patients, particularly in the case of change in treatment course. Concerning the risk of cancer, no increased risk inherent to SpA seems to exist. However, an increased neoplastic risk can occur due to SpA treatments, e.g., P UVA. Data are sparse on the risk of infections compared with rheumatoid arthritis, but there appears to be no risk in the absence of TNF-inhibitor exposure. Regardless of which comorbidity, a gap exists between recommendations for their management and actual implementation in clinical practice, suggesting that there is still a need for improvement in this area. Systematic screening for these comorbidities should improve both short- and long-term outcomes in SpA patients. PMID- 29594125 TI - Attribution of Neuropsychiatric Manifestations to Systemic Lupus Erythematosus. AB - Neuropsychiatric (NP) involvement in systemic lupus erythematosus (SLE) is one of the most severe manifestations of the disease that has a heavy impact on patient's functioning, quality of life, and disease outcome. The prevalence is highly variable and the clinical phenotypes vary from common syndromes to rare NP entities. Its occurrence may be the result of a primary manifestation of SLE, secondary to other conditions (such as infections or metabolic disturbances) or the effect of concomitant comorbidities that often complicate the disease course. Correct attribution of NP events may pose diagnostic challenges and it is a critical factor in selecting the correct management. Although there is still no diagnostic gold standard to rightly diagnose NPSLE syndromes, great advances have been made in improving the clinician judgment in the evaluation process. In this narrative review, we present and discuss available evidence concerning NPSLE with a special focus on the attribution models developed using composite decision rules to ascribe NP events to SLE. PMID- 29594126 TI - Emerging Infectious Agents and Blood Safety in Latin America. AB - Historically, emerging infectious agents have been an important driving force toward the enhancement of blood safety, illustrated by the sharp reduction in the transmission of infectious agents by blood transfusion after human immunodeficiency virus (HIV) epidemics. In general, Latin American (LATAM) countries have introduced screening for microorganisms with proven blood transmission with some delay in comparison to developed countries, but, nowadays, all LATAM countries comply with a minimum standard of screening which includes Hepatitis B, C, HIV, Treponema pallidum, and Trypanosoma cruzi. Noticeably, all those agents, in addition to HTLV, cause chronic infections. By contrast, in the last decade, the region has witnessed explosive outbreaks of arboviral diseases, representing a new challenge to the blood system, threatening not only blood safety but also availability. So far, the clinical impact of transfusion transmitted Dengue, Chikungunya, or Zika has not been evident, precluding immediate reaction from the authorities. A number of other arboviruses are endemic in the region and may, unpredictably, originate new epidemics. Several measures must be taken in preparedness for the potential emergence of another arbodisease. PMID- 29594127 TI - Effect of Eicosapentaenoic Acid and Docosahexaenoic Acid on Myogenesis and Mitochondrial Biosynthesis during Murine Skeletal Muscle Cell Differentiation. AB - Polyunsaturated fatty acids are important nutrients for human health, especially omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been found to play positive roles in the prevention of various diseases. However, previous studies have reported that excessive omega-3 fatty acids supplement during pregnancy caused side effects such as slower neural transmission times and postnatal growth restriction. In this study, we investigated the effect of EPA and DHA on mitochondrial function and gene expression in C2C12 myoblasts during skeletal muscle differentiation. C2C12 myoblasts were cultured to confluency and then treated with differentiation medium that contained fatty acids (50-uM EPA and DHA). After 72 h of myogenic differentiation, mRNA was collected, and gene expression was analyzed by real time PCR. Microscopy was used to examine cell morphology following treatment with fatty acids. The effect of EPA and DHA on cellular oxygen consumption was measured using a Seahorse XF24 Analyzer. Cells treated with fatty acids had fewer myotubes formed (P <= 0.05) compared with control cells. The expression of the genes related to myogenesis was significantly lower (P <= 0.05) in cells treated with fatty acids, compared with control cells. Genes associated with adipogenesis had higher (P <= 0.05) expression after treatment with fatty acids. Also, the mitochondrial biogenesis decreased with lower (P <= 0.05) gene expression and lower (P <= 0.05) mtDNA/nDNA ratio in cells treated with fatty acids compared with control cells. However, the expression of genes related to peroxisome biosynthesis was higher (P <= 0.05) in cells treated with fatty acids. Moreover, fatty-acid treatment reduced (P <= 0.05) oxygen consumption rate under oligomycin inhibited (reflecting proton leak) and uncoupled conditions. Our data imply that fatty acids might reduce myogenesis and increase adipogenesis in myotube formation. Fatty acids may also decrease cell metabolism by reducing mitochondrial biogenesis as well as respiration rate. This study suggests that the maternal overdosage of EPA and DHA may influence fetal muscle development, increase intramuscular adipose tissue deposition in offspring, and have a long term effect on the development of metabolic diseases such as obesity and diabetes in adult offspring. PMID- 29594128 TI - Preadministration of Fermented Sorghum Diet Provides Protection against Hyperglycemia-Induced Oxidative Stress and Suppressed Glucose Utilization in Alloxan-Induced Diabetic Rats. AB - Sorghum bicolor grains are rich in phytochemicals known to considerably impact human health. Several health-promoting products such as flour, staple food, and beverages have been produced from sorghum grains. This study investigated the protective and modulatory effects of a sorghum diet on the genes of some antioxidant and glycolytic enzymes in alloxan-induced diabetic rats. The rats were randomly distributed into six groups: the control group received normal diet, while the other groups were pretreated with 12.5, 25, 50, 75, and 100% of the sorghum diets daily for 8 weeks before the administration of a dose of alloxan (100 mg/kg BW), after which blood was collected and the liver was excised. The effects of the diets on blood glucose levels, liver dysfunction indices, and markers of oxidative stress were assessed spectrophotometrically, while the gene expressions of key glycolytic enzymes and enzymatic antioxidants were assayed using reverse transcriptase polymerase chain reaction. It was observed that the pretreatment of the experimental animals with the diets normalized the blood glucose before and after the administration of alloxan. The sorghum-treated groups also showed statistically significant (p < 0.05) decrease in liver dysfunction indices and markers of oxidative damage compared with the control. In addition, statistically the diets significantly decreased (p < 0.05) the relative expression of superoxide dismutase, glutathione peroxidase, glucokinase, phosphofructokinase, and hexokinase genes in the experimental animals compared with the control. Overall, this study showed that the preadministration of fermented sorghum diet significantly protected against hyperglycemia and suppressed glucose utilization via glycolysis in the liver of alloxan-induced diabetic rats. Thus, the consumption of sorghum diet may protect against hyperglycemia and oxidative damage and may therefore serve as functional food for management of diabetic mellitus. PMID- 29594130 TI - Rubisco Assembly in the Chloroplast. AB - Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the rate limiting step in the Calvin-Benson cycle, which transforms atmospheric carbon into a biologically useful carbon source. The slow catalytic rate of Rubisco and low substrate specificity necessitate the production of high levels of this enzyme. In order to engineer a more efficient plant Rubisco, we need to better understand its folding and assembly process. Form I Rubisco, found in green algae and vascular plants, is a hexadecamer composed of 8 large subunits (RbcL), encoded by the chloroplast genome and 8 small, nuclear-encoded subunits (RbcS). Unlike its cyanobacterial homolog, which can be reconstituted in vitro or in E. coli, assisted by bacterial chaperonins (GroEL-GroES) and the RbcX chaperone, biogenesis of functional chloroplast Rubisco requires Cpn60-Cpn20, the chloroplast homologs of GroEL-GroES, and additional auxiliary factors, including Rubisco accumulation factor 1 (Raf1), Rubisco accumulation factor 2 (Raf2) and Bundle sheath defective 2 (Bsd2). The discovery and characterization of these factors paved the way for Arabidopsis Rubisco assembly in E. coli. In the present review, we discuss the uniqueness of hetero-oligomeric chaperonin complex for RbcL folding, as well as the sequential or concurrent actions of the post chaperonin chaperones in holoenzyme assembly. The exact stages at which each assembly factor functions are yet to be determined. Expression of Arabidopsis Rubisco in E. coli provided some insight regarding the potential roles for Raf1 and RbcX in facilitating RbcL oligomerization, for Bsd2 in stabilizing the oligomeric core prior to holoenzyme assembly, and for Raf2 in interacting with both RbcL and RbcS. In the long term, functional characterization of each known factor along with the potential discovery and characterization of additional factors will set the stage for designing more efficient plants, with a greater biomass, for use in biofuels and sustenance. PMID- 29594131 TI - A Genome-Wide Search for Bipolar Disorder Risk Loci Modified by Mitochondrial Genome Variation. AB - Mitochondrial DNA mutations have been reported to be associated with bipolar disorder (BD). In this study, we performed genome-wide analyses to assess mitochondrial single-nucleotide polymorphism (mtSNP) effects on BD risk and early onset BD (EOBD) among BD patients, focusing on interaction effects between nuclear SNPs (nSNPs) and mtSNPs. Common nSNP and mtSNP data from European American BD cases (n = 1,001) and controls (n = 1,034) from the Genetic Association Information Network BD study were analyzed to assess the joint effect of nSNP and nSNP-mtSNP interaction on the risk of BD and EOBD. The effect of nSNP mtSNP interactions was also assessed. For BD risk, the strongest evidence of an association was obtained for nSNP rs1880924 in MGAM and mtSNP rs3088309 in CytB (pjoint = 8.2 * 10-8, pint = 1.4 * 10-4). Our results also suggest that the minor allele of the nSNP rs583990 in CTNNA2 increases the risk of EOBD among carriers of the mtSNP rs3088309 minor allele, while the nSNP has no effect among those carrying the mtSNP major allele (OR = 4.53 vs. 1.05, pjoint = 2.1 * 10-7, pint = 1.16 * 10-6). While our results are not statistically significant after multiple testing correction and a large-sample replication is required, our exploratory study demonstrates the potential importance of considering the mitochondrial genome for identifying genetic factors associated with BD. PMID- 29594129 TI - Chromatin-Bound Cullin-Ring Ligases: Regulatory Roles in DNA Replication and Potential Targeting for Cancer Therapy. AB - Cullin-RING (Really Interesting New Gene) E3 ubiquitin ligases (CRLs), the largest family of E3 ubiquitin ligases, are functional multi-subunit complexes including substrate receptors, adaptors, cullin scaffolds, and RING-box proteins. CRLs are responsible for ubiquitination of ~20% of cellular proteins and are involved in diverse biological processes including cell cycle progression, genome stability, and oncogenesis. Not surprisingly, cullins are deregulated in many diseases and instances of cancer. Recent studies have highlighted the importance of CRL-mediated ubiquitination in the regulation of DNA replication/repair, including specific roles in chromatin assembly and disassembly of the replication machinery. The development of novel therapeutics targeting the CRLs that regulate the replication machinery and chromatin in cancer is now an attractive therapeutic strategy. In this review, we summarize the structure and assembly of CRLs and outline their cellular functions and their diverse roles in cancer, emphasizing the regulatory functions of nuclear CRLs in modulating the DNA replication machinery. Finally, we discuss the current strategies for targeting CRLs against cancer in the clinic. PMID- 29594132 TI - Interleukin-17 Alteration in First-Episode Psychosis: A Meta-Analysis. AB - Schizophrenia is accompanied with central nervous system and peripheral immune system imbalances. Interleukin-17 (IL-17) is implicated in various immune and inflammatory processes. Aberrant levels of IL-17 have been reported in patients with schizophrenia, whereas the results are not consistent. To clarify the relationship between IL-17 and schizophrenia, we performed a meta-analysis in this study. We carried out a structured literature search in PubMed and Embase database up to April 16, 2017, and retrieved all eligible case-control studies according to the inclusion criteria. Finally, a total of 313 patients with drug naive first-episode psychosis and 238 healthy control subjects from 5 studies were included in our meta-analysis. There were no significant differences between first-episode psychosis patients and healthy controls with respect to the levels of IL-17 (p = 0.21), even when we removed 2 studies which were not European samples (p = 0.12). Our findings suggested that IL-17 may not be involved in the pathological mechanism of schizophrenia. PMID- 29594133 TI - Improved Scalability of Neuron-Based Phenotypic Screening Assays for Therapeutic Discovery in Neuropsychiatric Disorders. AB - There is a pressing need to improve approaches for drug discovery related to neuropsychiatric disorders (NSDs). Therapeutic discovery in neuropsychiatric disorders would benefit from screening assays that can measure changes in complex phenotypes linked to disease mechanisms. However, traditional assays that track complex neuronal phenotypes, such as neuronal connectivity, exhibit poor scalability and are not compatible with high-throughput screening (HTS) procedures. Therefore, we created a neuronal phenotypic assay platform that focused on improving the scalability and affordability of neuron-based assays capable of tracking disease-relevant phenotypes. First, using inexpensive laboratory-level automation, we industrialized primary neuronal culture production, which enabled the creation of scalable assays within functioning neural networks. We then developed a panel of phenotypic assays based on culturing of primary neurons from genetically modified mice expressing HTS compatible reporters that capture disease-relevant phenotypes. We demonstrated that a library of 1,280 compounds was quickly screened against both assays using only a few litters of mice in a typical academic laboratory setting. Finally, we implemented one assay in a fully automated high-throughput academic screening facility, illustrating the scalability of assays designed using this platform. These methodological improvements simplify the creation of highly scalable neuron based phenotypic assays designed to improve drug discovery in CNS disorders. PMID- 29594134 TI - The COMT Val158Met Polymorphism and Exploratory Behavior in Bipolar Mania. AB - Background: The catechol-O-methyltransferase (COMT) Val158Met gene influences cognition and behavior in psychiatric illnesses; its low-activity allele, methionine (Met), may be associated with behavior reflecting catecholamine overactivity. Heightened motor activity and increased positive valence are central features of bipolar disorder (BD) and have been quantified in the human Behavioral Pattern Monitor (hBPM), an exploration paradigm based upon the rodent open field. We examined whether hBPM behavior was related to the COMT gene in a small sample of manic BD patients. Methods: Twenty-six acutely hospitalized manic BD patients were genotyped for the COMT Val158Met polymorphism and tested in the hBPM, an unfamiliar room containing novel objects. Movements around the hBPM and object interactions were video-recorded for 15 min and rated. Results: Met homozygote BD patients demonstrated significantly more interactions with multiple objects and more time spent with objects in the hBPM. Valine (Val) homozygote patients exhibited the least object exploration, while heterozygote patients demonstrated intermediate levels. Conclusion: This preliminary study suggests that arousal and positive valence are influenced in a linear fashion by COMT, presumably due to increased catecholamine in frontal regions, but these findings require replication in a larger sample. The hBPM can enable cross-species and transdiagnostic studies to inform neurobiology of psychiatric disorders. PMID- 29594135 TI - Mitochondrial Complex I Deficiency in Schizophrenia and Bipolar Disorder and Medication Influence. AB - Subjects with schizophrenia (SZ) and bipolar disorder (BD) show decreased protein and transcript levels for mitochondrial complex I. In vitro results suggest antipsychotic and antidepressant drugs may be responsible. We measured complex I activity in BD, SZ, and controls and presence of antipsychotic and antidepressant medications, mitochondrial DNA (mtDNA) copy number, and the mtDNA "common deletion" in the brain. Complex I activity in the prefrontal cortex was decreased by 45% in SZ compared to controls (p = 0.02), while no significant difference was found in BD. Complex I activity was significantly decreased (p = 0.01) in pooled cases (SZ and BD) that had detectable psychotropic medications and drugs compared to pooled cases with no detectable levels. Subjects with age at onset in their teens and psychotropic medications showed decreased (p < 0.05) complex I activity compared to subjects with an adult age at onset. Both SZ and BD groups displayed significant increases (p < 0.05) in mtDNA copy number compared to controls; however, common deletion burden was not altered. Complex I deficiency is found in SZ brain tissue, and psychotropic medications may play a role in mitochondrial dysfunction. Studies of medication-free first-episode psychosis patients are needed to elucidate whether mitochondrial pathophysiology occurs independent of medication effects. PMID- 29594136 TI - Crossing the Worm-Brain Barrier by Using Caenorhabditis elegans to Explore Fundamentals of Human Psychiatric Illness. AB - Endophenotypes and Research Domain Criteria (RDoC) represent recent efforts to deconvolute psychiatric illnesses into fundamental symptom clusters or biological markers more closely linked to genetic influences. By taking this one step farther, these biomarkers can be reduced to protophenotypes - endophenotypes conserved during evolution - with counterparts in lower organisms including Caenorhabditis elegans and Drosophila. Striking conservation in C. elegans of genes that increase the risk for mental illness bolsters the relevance of this model system for psychiatric research. Here, I review the characterization of several protophenotypes that are relevant for asociality, avolition/anhedonia, prepulse inhibition, and anorexia. Interestingly, the analogous behavioral defects in C. elegans are also corrected by psychotropic drugs used to treat the corresponding symptoms in man and/or are mediated by the same neurotransmitters. Overall, there is much we can learn about the complex human brain by studying simpler nervous systems directing evolutionarily conserved behaviors. The potential for generating important new insights from model organisms appears limitless when we begin to recognize the vestiges of evolution in ourselves. PMID- 29594137 TI - Artificial Intelligence for the Artificial Kidney: Pointers to the Future of a Personalized Hemodialysis Therapy. AB - Background: Current dialysis devices are not able to react when unexpected changes occur during dialysis treatment or to learn about experience for therapy personalization. Furthermore, great efforts are dedicated to develop miniaturized artificial kidneys to achieve a continuous and personalized dialysis therapy, in order to improve the patient's quality of life. These innovative dialysis devices will require a real-time monitoring of equipment alarms, dialysis parameters, and patient-related data to ensure patient safety and to allow instantaneous changes of the dialysis prescription for the assessment of their adequacy. The analysis and evaluation of the resulting large-scale data sets enters the realm of "big data" and will require real-time predictive models. These may come from the fields of machine learning and computational intelligence, both included in artificial intelligence, a branch of engineering involved with the creation of devices that simulate intelligent behavior. The incorporation of artificial intelligence should provide a fully new approach to data analysis, enabling future advances in personalized dialysis therapies. With the purpose to learn about the present and potential future impact on medicine from experts in artificial intelligence and machine learning, a scientific meeting was organized in the Hospital Universitari Bellvitge (L'Hospitalet, Barcelona). As an outcome of that meeting, the aim of this review is to investigate artificial intel ligence experiences on dialysis, with a focus on potential barriers, challenges, and prospects for future applications of these technologies. Summary and Key Messages: Artificial intelligence research on dialysis is still in an early stage, and the main challenge relies on interpretability and/or comprehensibility of data models when applied to decision making. Artificial neural networks and medical decision support systems have been used to make predictions about anemia, total body water, or intradialysis hypotension and are promising approaches for the prescription and monitoring of hemodialysis therapy. Current dialysis machines are continuously improving due to innovative technological developments, but patient safety is still a key challenge. Real-time monitoring systems, coupled with automatic instantaneous biofeedback, will allow changing dialysis prescriptions continuously. The integration of vital sign monitoring with dialysis parameters will produce large data sets that will require the use of data analysis techniques, possibly from the area of machine learning, in order to make better decisions and increase the safety of patients. PMID- 29594138 TI - Changes in the Spectrum of Kidney Diseases: An Analysis of 40,759 Biopsy-Proven Cases from 2003 to 2014 in China. AB - Objectives: To evaluate the changing spectrum of kidney diseases over time in China using renal biopsy-proven cases. Methods: All patients over the age of 14 years who were diagnosed with a kidney disease by renal biopsy in the Renal Biopsy Registry of the National Clinical Research Center of Kidney Diseases in Jinling Hospital, Nanjing, from 2003 to 2014 were included. Results: In total, 40,759 cases of renal biopsy were analyzed. The mean age of the patients was 36.59 +/- 14.12 years. 52.0$ of the patients were male. Primary glomerulonephritis (PGN), secondary glomerulonephritis, tubulointerstitial disease, and hereditary renal diseases accounted for 67.1, 26.4, 2.9, and 2.5$, respectively. IgA nephropathy (IgAN), membranous nephropathy (MN), minimal change disease, and focal segmental glomerulosclerosis were the leading PGN diagnoses. The frequency of MN increased significantly (p < 0.001) by doubling from 2003 to 2014. An analysis by age category indicated that the frequency of MN increased significantly over time (p < 0.001) in all age categories and increased by more than 2 times in the 14-24 age category. Lupus nephritis (LN) and Henoch-Schonlein purpura nephritis (HSPN) decreased significantly (p < 0.001), diabetic nephropathy (DN) increased nearly twice (p < 0.001), monoclonal immunoglobulin deposition disease (MIDD) tripled (p < 0.001), and hypertensive nephropathy (HT) (p < 0.001) and renal amyloidosis (AMY) (p < 0.05) showed an upward trend. An analysis by age category showed that hepatitis B-related nephritis has significantly decreased in the 14-24 age category (p < 0.001). Conclusion: PGN continued to be the predominant kidney disease in China with IgAN being the most common PGN. The frequency of MN increased significantly, with a maximum increase in young adults. LN and HSPN decreased significantly, DN and MIDD increased significantly, and HT and AMY also showed an increasing trend. The kidney disease trends presented in this study serve as a reference point for patient care, disease prevention, and public health interventions. PMID- 29594139 TI - The Relationship of Residual Renal Function with Cardiovascular Morbidity in Hemodialysis Patients and the Potential Role of Monocyte Chemoattractant Protein 1. AB - Background: Residual renal function (RRF) provides several benefits to patients on dialysis. Monocyte chemoattractant protein-1 (MCP-1) plays an important role in atherosclerotic lesions. We considered the relationship between RRF and cardiovascular morbidity and the significant role of MCP-1 serum concentrations in hemodiafiltration (HDF) patients. Methods: We enrolled 76 patients on on-line HDF. RRF was defined by interdialytic urine output, and we studied the patients in two groups according to the preservation or not of urine output. MCP-1 levels were measured using enzyme-linked immunosorbent assay. chi2 tests were applied for the association between RRF and left ventricular hypertrophy (LVH), coronary artery disease (CAD), peripheral artery disease (PAD), and systolic and diastolic cardiac dysfunction. We built an adjusted model using logistic regression analysis for the factors which might impact on the loss of urine output. Results: chi2 tests showed a significant association between the loss of urine output and LVH, diastolic dysfunction, and PAD (chi2 = 7.4, p = 0.007; chi2 = 14.3, p = 0.001; chi2 = 4.2, p = 0.03, respectively), although the association with CAD and systolic dysfunction was found to be nonsignificant. The patients without RRF had significantly higher MCP-1, and the urine volume was inversely associated with MCP-1 (r = -465, p = 0.03). In the built adjusted model, the elevated MCP-1 was found to be a significant predictor for the loss of RRF. Conclusion: The loss of RRF was significantly associated with LVH, diastolic dysfunction, and PAD in HDF patients. The increased MCP-1, affected by the lack of urine, may act as an additional underlying factor on this relationship, reflecting a progressive inflammation/oxidative stress condition. PMID- 29594140 TI - TREM-1 Contributes to Inflammation in IgA Nephropathy. AB - Background: Circulating IgA1-containing immune complexes (cIgA1) were shown to play important roles in IgA nephropathy (IgAN). They could induce the release of multiple inflammatory factors, including MCP-1 and IL-6, and elevated urinary inflammatory factors were also reported in patients with IgAN, which suggested that inflammation is a major contributor to kidney injury in IgAN. After the previous identification of the upregulated release of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) by mesangial cells under cIgA1 challenge using cytokine array, in the present study, we further explored the role of TREM 1, an amplifier of inflammation, in cIgA1-induced kidney injury. Methods: In total, 35 patients with IgAN and 17 healthy controls were enrolled. The cIgA1 was isolated from plasma and used to treat cultured mesangial cells. The mRNA expression of TREM-1 as well as levels of sTREM-1, MCP-1, and IL-6 in the mesangial cell supernatant and urine samples were detected. Results: We found that cIgA1 from patients with IgAN could significantly upregulate the expression of TREM-1 in mesangial cells compared to healthy controls. The levels of DeltasTREM-1 were positively correlated with MCP-1 levels in the mesangial supernatant. Similarly, higher urinary levels of sTREM-1 were also observed in patients with IgAN compared to healthy controls. Moreover, IgAN patients with detectable urinary sTREM-1 presented with severe clinical and pathological manifestations, including higher IgA and lower eGFR levels, compared to patients whose urinary sTREM-1 levels were below the limit of quantification. Conclusion: Our present study suggested that TREM-1 in cIgA1 induced inflammatory kidney injury in IgAN.

AB - Rare bacteria can lead to infective endocarditis, which may lead to renal involvement as severe glomerulonephritis. We report our experience of a 12-year old child who presented with infective endocarditis and blood culture-grown Gemella morbillorum - a rarely reported bacteria. The clinical picture was further complicated with severe glomerulonephritis. Renal biopsy was suggestive of crescentic glomerulonephritis. The child was managed with antibiotics, steroids, and plasmapheresis and responded well to the treatment. To our knowledge, this is the first report of G. morbillorum endocarditis with immune complex deposition and necrotizing glomerulonephritis in a child. PMID- 29594141 TI - What We Do and Do Not Know about Women and Kidney Diseases; Questions Unanswered and Answers Unquestioned: Reflection on World Kidney Day and International Women's Day. AB - Chronic kidney disease affects approximately 10$ of the world's adult population: it is within the top 20 causes of death worldwide, and its impact on patients and their families can be devastating. World Kidney Day and International Women's Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women's health and specifically their kidney health, on the community and the next generations, as well as to strive to be more curious about the unique aspects of kidney disease in women so that we may apply those learnings more broadly. Girls and women, who make up approximately 50$ of the world's population, are important contributors to society and their families. Gender differences continue to exist around the world in access to education, medical care, and participation in clinical studies. Pregnancy is a unique state for women, offering an opportunity for diagnosis of kidney disease, but also a state where acute and chronic kidney diseases may manifest, and which may impact future generations with respect to kidney health. There are various autoimmune and other conditions that are more likely to have an impact on women, with profound consequences for child bearing, and on the fetus. Women have different complications on dialysis than men, and are more likely to be donors than recipients of kidney transplants. In this editorial, we focus on what we do and do not know about women, kidney health, and kidney disease, and what we might learn in the future to improve outcomes worldwide. PMID- 29594143 TI - A Case of Crescentic Glomerulonephritis Complicated with Hypocomplementemic Urticarial Vasculitis Syndrome and ANCA-Associated Vasculitis. AB - Systemic urticaria in a 64-year-old woman was diagnosed as leukocytoclastic vasculitis by a punch biopsy of the skin. Her physical findings improved after prescription of prednisolone at a dose of 20 mg/day, but the skin rash relapsed with renal dysfunction, proteinuria, and hematuria when the dose of prednisolone was reduced over a period of 9 months to 1 mg/day. She was admitted to our institute for further examination, when urinary protein and plasma creatinine levels were 0.8 g/day and 1.7 mg/dL, respectively. Complement analysis showed that levels of total hemolytic component, component C3 fraction, and component C4 fraction were 30~60% of normal values and the titer of anti-neutrophil cytoplasmic antibody for myeloperoxidase (MPO-ANCA) was 89 EU (normal range, <10 EU), though there were no immunologic disorders such as systemic lupus erythematosus. Cellular crescentic glomerulonephritis was observed by light microscopy, and immunofluorescent studies showed positive staining for IgG, IgM, C3, C4, and C1q. Electron microscopy showed mesangial and subendothelial deposits with circumferential mesangial interposition. She fulfilled the diagnostic criteria for hypocomplementemic urticarial vasculitis syndrome (HUV), and ANCA associated vasculitis (AAV) was also indicated by small vessel vasculitis and positive MPO-ANCA. Steroid pulse therapy with methylprednisolone followed by oral prednisolone improved her general condition and hypocomplementemia, and MPO-ANCA became negative. HUV and AAV are distinct clinical disorders, though both affect small blood vessels. Here we report a case of AAV-complicated HUV with crescentic glomerulonephritis. PMID- 29594144 TI - An Unexpected Case of Scurvy in a Peritoneal Dialysis Patient. AB - This case describes an obese adult male peritoneal dialysis patient who presented with a pruritic follicular rash. Nutrient deficiency was not suspected initially in this case because there was no history of protein-calorie malnutrition, but the patient reported a diet devoid of fruits and vegetables and had not been taking his dialysis vitamin as prescribed. Skin biopsy showed follicular hyperkeratosis with fragmented hair shafts and corkscrew hairs consistent with scurvy. After supplementation with ascorbic acid 500 mg twice daily for 2 weeks, the rash resolved completely. Dialysis patients are at increased risk for vitamin C deficiency due to indiscriminant clearance of the nutrient with dialysis, but scurvy is rarely seen. PMID- 29594145 TI - Exit Site Infection due to Mycobacterium chelonae in an Elderly Patient on Peritoneal Dialysis. AB - Nontuberculous mycobacteria (NTM) are rarely isolated from peritoneal dialysis (PD)-associated catheter infections. However, NTM infection is usually difficult to treat and leads to catheter loss. Prompt diagnosis is essential for appropriate treatment. A 70-year-old Japanese man who had been on PD for 2 years and with a medical history of 2 episodes of exit site infections (ESIs) due to methicillin-resistant Staphylococcus aureus was admitted to the hospital due to suspected ESI recurrence. However, Gram staining of the pus revealed no gram positive cocci. Instead, weakly stained gram-positive rods were observed after 7 days of incubation, which were also positive for acid-fast staining. Rapidly growing NTM Mycobacterium chelonae was isolated on day 14. Despite administering a combination antibiotic therapy, ESI could not be controlled, and catheter removal surgery was performed on day 21. Although PD was discontinued temporarily, the patient did not require hemodialysis, without any uremic symptoms. The catheter was reinserted on day 48, and PD was reinitiated on day 61. The patient was discharged on day 65. Antibiotic therapy was continued for 3 months after discharge, with no indications of recurrent infections observed. It is important to consider the risk of NTM infections in patients on PD. Acid-fast staining could be a key test for prompt diagnosis and provision of an appropriate treatment. PMID- 29594146 TI - Early Conversion from Tacrolimus to Belatacept in a Highly Sensitized Renal Allograft Recipient with Calcineurin Inhibitor-Induced de novo Post-Transplant Hemolytic Uremic Syndrome. AB - Background: Kidney transplantation is the first-line therapy for patients with end-stage renal disease since it offers greater long-term survival and improved quality of life when compared to dialysis. The advent of calcineurin inhibitor (CNI)-based maintenance immunosuppression has led to a clinically significant decline in the rate of acute rejection and better short-term graft survival rates. However, these gains have not translated into improvement in long-term graft survival. CNI-related nephrotoxicity and metabolic side effects are thought to be partly responsible for this. Case Presentation: Here, we report the conversion of a highly sensitized renal transplant recipient with pretransplant donor-specific antibodies from tacrolimus to belatacept within 1 week of transplantation. This substitution was necessitated by the diagnosis of CNI induced de novo post-transplant hemolytic uremic syndrome. Conclusion: Belatacept is a novel costimulation blocker that is devoid of the nephrotoxic properties of CNIs and has been shown to positively impact long-term graft survival and preserve renal allograft function in low-immunologic-risk kidney transplant recipients. Data regarding its use in patients who are broadly sensitized to human leukocyte antigens are scarce, and the increased risk of rejection associated with belatacept has been a deterrent to more widespread use of this immunosuppressive agent. This case serves as an example of a highly sensitized patient that has been successfully converted to a belatacept-based CNI-free regimen. PMID- 29594147 TI - Oxcarbazepine Therapy for Complete Central Diabetes Insipidus. AB - Oxcarbazepine and carbamazepine cause hyponatremia by unknown mechanisms. We describe a patient with complete central diabetes insipidus and seizures who developed worsening hyponatremia when her dose of oxcarbazepine was increased. The patient maintained a normal serum sodium level and has had appropriately concentrated urine for 5 years on just oxcarbazepine, despite undetectable antidiuretic hormone (ADH) levels. This suggests that oxcarbazepine (or one of its metabolites) may stimulate collecting tubule V2 receptor-G protein complex independent of ADH, resulting in increased renal tubular water reabsorption. Oxcarbazepine may be useful as an alternative therapy for patients with central diabetes insipidus. PMID- 29594148 TI - C3 Glomerulopathy and Atypical Hemolytic Uremic Syndrome: Two Important Manifestations of Complement System Dysfunction. AB - The advances in our understanding of the alternative pathway have emphasized that uncontrolled hyperactivity of this pathway causes 2 distinct disorders that adversely impact the kidney. In the so-called atypical hemolytic uremic syndrome (aHUS), renal dysfunction occurs along with thrombocytopenia, anemia, and target organ injury to multiple organs, most commonly the kidney. On the other hand, in the so-termed C3 glomerulopathy, kidney involvement is not associated with thrombocytopenia, anemia, or other system involvement. In this report, we present 2 cases of alternative pathway dysfunction. The 60-year-old female patient had biopsy-proven C3 glomerulopathy, while the 32-year-old female patient was diagnosed with aHUS based on renal dysfunction, thrombocytopenia, anemia, and normal ADAMTS-13 level. The aHUS patient was successfully treated with the monoclonal antibody (eculizumab) for complement blockade. The patient with C3 glomerulopathy did not receive the monoclonal antibody. In this patient, management focused on blood pressure and proteinuria control with an angiotensin converting enzyme inhibitor. This article focuses on the clinical differences, pathophysiology, and treatment of aHUS and C3 glomerulopathy. PMID- 29594149 TI - Temporal Dynamics of Gene Expression During Endothelial Cell Differentiation From Human iPS Cells: A Comparison Study of Signalling Factors and Small Molecules. AB - Endothelial cell (EC) therapy may promote vascular growth or reendothelization in a variety of disease conditions. However, the production of a cell therapy preparation containing differentiated, dividing cells presenting typical EC phenotype, functional properties and chemokine profile is challenging. We focused on comparative analysis of seven small molecule-mediated differentiation protocols of ECs from human induced pluripotent stem cells. Differentiated cells showed a typical surface antigen pattern of ECs as characterized with flow cytometry analysis, functional properties, such as tube formation and ability to uptake acetylated LDL. Gene expression analysis by RNA sequencing revealed an efficient silencing of pluripotency genes and upregulation of genes related to cellular adhesion during differentiation. In addition, distinct patterns of transcription factor expression were identified during cellular reprogramming providing targets for more effective differentiation protocols in the future. Altogether, our results suggest that the most optimal EC differentiation protocol includes early inhibition of Rho-associated coiled-coil kinase and activation of cyclic AMP signaling, and inhibition of transforming growth factor beta signaling after mesodermal stage. These findings provide the first systematic characterization of the most potent signalling factors and small molecules used to generate ECs from human induced pluripotent stem cells and, consequently, this work improves the existing EC differentiation protocols and opens up new avenues for controlling cell fate for regenerative EC therapy. PMID- 29594150 TI - Mechanotransduction in Coronary Vein Graft Disease. AB - Autologous saphenous veins are the most commonly used conduits in revascularization of the ischemic heart by coronary artery bypass graft surgery, but are subject to vein graft failure. The current mini review aims to provide an overview of the role of mechanotransduction signalling underlying vein graft failure to further our understanding of the disease progression and to improve future clinical treatment. Firstly, limitation of damage during vein harvest and engraftment can improve outcome. In addition, cell cycle inhibition, stimulation of Nur77 and external grafting could form interesting therapeutic options. Moreover, the Hippo pathway, with the YAP/TAZ complex as the main effector, is emerging as an important node controlling conversion of mechanical signals into cellular responses. This includes endothelial cell inflammation, smooth muscle cell proliferation/migration, and monocyte attachment/infiltration. The combined effects of expression levels and nuclear/cytoplasmic translocation make YAP/TAZ interesting novel targets in the prevention and treatment of vein graft disease. Pharmacological, molecular and/or mechanical conditioning of saphenous vein segments between harvest and grafting may potentiate targeted and specific treatment to improve long-term outcome. PMID- 29594151 TI - Advances in Pathophysiology of Calcific Aortic Valve Disease Propose Novel Molecular Therapeutic Targets. AB - Calcific Aortic Valve Disease (CAVD) is the most common heart valve disease and its incidence is expected to rise with aging population. No medical treatment so far has shown slowing progression of CAVD progression. Surgery remains to this day the only way to treat it. Effective drug therapy can only be achieved through a better insight into the pathogenic mechanisms underlying CAVD. The cellular and molecular events leading to leaflets calcification are complex. Upon endothelium cell damage, oxidized LDLs trigger a proinflammatory response disrupting healthy cross-talk between valve endothelial and interstitial cells. Therefore, valve interstitial cells transform into osteoblasts and mineralize the leaflets. Studies have investigated signaling pathways driving and connecting lipid metabolism, inflammation and osteogenesis. This review draws a summary of the recent advances and discusses their exploitation as promising therapeutic targets to treat CAVD and reduce valve replacement. PMID- 29594152 TI - Ionizing Radiation Induces Endothelial Inflammation and Apoptosis via p90RSK Mediated ERK5 S496 Phosphorylation. AB - Adverse cardiovascular events are a leading nonmalignant cause of morbidity and mortality among cancer survivors who have been exposed to ionizing radiation (IR), but the exact mechanism of the cardiovascular complications induced by IR remains unclear. In this study we investigated the potential role of the p90RSK ERK5 module in regulating IR-induced endothelial cell inflammation and apoptosis. Whole body radiation of mice with 2 Gy gamma-ray significantly increased endothelial VCAM-1 expression; especially in the disturbed flow area in vivo. In vitro studies showed that IR increased p90RSK activation as well as subsequent ERK5 S496 phosphorylation in cultured human endothelial cells (ECs). A specific p90RSK inhibitor, FMK-MEA, significantly inhibited both p90RSK activation and ERK5 S496 phosphorylation, but it had no effect on IR-induced ERK5 TEY motif phosphorylation, suggesting that p90RSK regulates ERK5 transcriptional activity, but not its kinase activity. In fact, we found that IR-induced NF-kB activation and VCAM-1 expression in ECs were significantly inhibited by the over-expression of S496 phosphorylation site mutant of ERK5 (ERK5 S496A) compared to overexpression of wild type ERK5. Furthermore, when ECs were exposed to IR, the number of annexin V positive cells increased, and overexpression of ERK5 S496A, but not wild type ERK5, significantly inhibited this increase. Our results demonstrate that IR augmented disturbed flow-induced VCAM-1 expression in vivo. Endothelial p90RSK was robustly activated by IR and subsequently up-regulated ERK5 S496 phosphorylation, inflammation, and apoptosis in ECs. The EC p90RSK-ERK5 signaling axis can be a good target to prevent cardiovascular events after radiation therapy in cancer patients. PMID- 29594153 TI - Evaluation of 25% Poloxamer As a Slow Release Carrier for Morphine in a Rat Model. AB - The objectives of this study were to evaluate poloxamer as a slow release carrier for morphine (M) and potential tissue irritation after subcutaneous poloxamer morphine (PM) injection in a rat model. Based on the result of a previous in vitro work, 25% poloxamer, with and without morphine, and saline were administered in 14 rats' flanks. Blood for morphine concentrations was automatically sampled at multiple preprogrammed time points using the CulexTM unit for 48 h. Skin tissues from the injection sites were harvested and evaluated for histopathological changes. Following M or PM administration, it was determined that the half-life (t1/2) was significantly longer in the PM (5.5 +/- 7.2 h) than M (0.7 +/- 0.8 h) indicated a slow dissolution of poloxamer with morphine. The tmax was within 15 min and Cmax was approximately three times higher with M than with PM, reaching 716.8 (+/-153.7 ng/ml) of plasma morphine concentrations. There was no significant difference in total area under the curve and clearance of M versus PM. Histology inflammatory scores were similar between M, PM, and poloxamer but were significantly higher than saline control. We concluded that 25% poloxamer was capable of increasing the t1/2 of morphine, without a significant tissue irritation. PMID- 29594154 TI - A Systems Approach to Evaluate One Health Initiatives. AB - Challenges calling for integrated approaches to health, such as the One Health (OH) approach, typically arise from the intertwined spheres of humans, animals, and ecosystems constituting their environment. Initiatives addressing such wicked problems commonly consist of complex structures and dynamics. As a result of the EU COST Action (TD 1404) "Network for Evaluation of One Health" (NEOH), we propose an evaluation framework anchored in systems theory to address the intrinsic complexity of OH initiatives and regard them as subsystems of the context within which they operate. Typically, they intend to influence a system with a view to improve human, animal, and environmental health. The NEOH evaluation framework consists of four overarching elements, namely: (1) the definition of the initiative and its context, (2) the description of the theory of change with an assessment of expected and unexpected outcomes, (3) the process evaluation of operational and supporting infrastructures (the "OH-ness"), and (4) an assessment of the association(s) between the process evaluation and the outcomes produced. It relies on a mixed methods approach by combining a descriptive and qualitative assessment with a semi-quantitative scoring for the evaluation of the degree and structural balance of "OH-ness" (summarised in an OH index and OH-ratio, respectively) and conventional metrics for different outcomes in a multi-criteria-decision-analysis. Here, we focus on the methodology for Elements (1) and (3) including ready-to-use Microsoft Excel spreadsheets for the assessment of the "OH-ness". We also provide an overview of Element (2), and refer to the NEOH handbook for further details, also regarding Element (4) (http://neoh.onehealthglobal.net). The presented approach helps researchers, practitioners, and evaluators to conceptualise and conduct evaluations of integrated approaches to health and facilitates comparison and learning across different OH activities thereby facilitating decisions on resource allocation. The application of the framework has been described in eight case studies in the same Frontiers research topic and provides first data on OH-index and OH-ratio, which is an important step towards their validation and the creation of a dataset for future benchmarking, and to demonstrate under which circumstances OH initiatives provide added value compared to disciplinary or conventional health initiatives. PMID- 29594155 TI - Effect of a Histone Demethylase Inhibitor on Equine Herpesvirus-1 Activity In Vitro. AB - Equine herpesvirus type 1 (EHV-1) is a ubiquitous and highly contagious pathogen that causes a range of disease severities with outbreaks of notable economic impact. Given the limitations in immune protection of current vaccines and the limited effectiveness of antiviral drugs on EHV-1 infections in vivo, improved treatment measures are needed to control disease. The use of drugs that alter the epigenetic state of herpes simplex virus genome has been shown to limit viral primary infection and reactivation both in vitro and in vivo. Therefore, we tested the hypothesis that maintaining a repressive epigenetic state on the EHV-1 genome in the host equine cell would decrease viral load during lytic infection. Equine fetal kidney cells (EFKCs) or isolated peripheral blood leukocytes were treated in vitro with (a) the nucleoside analog ganciclovir; (b) the histone demethylase inhibitor OG-L002; (c) both ganciclovir and OG-L002; or (d) dimethyl sulfoxide (DMSO, vehicle control); and then infected with a clinical EHV-1 isolate. Treatment of EFKCs with ganciclovir (mean 22.3 DNA copies per cell, p = 0.0005), OG-L002 (mean 25.6, p = 0.005) or both ganciclovir and OG-L002 (mean 7.1, p = 0.0001) resulted in decreased EHV-1 viral load at 24 h post-infection (hpi) in comparison with DMSO (mean 42.0), with greater impact using the combined treatment. Further, EHV-1 gene expression at 3 hpi decreased when EFKCs were infected in the presence of ganciclovir (p = 0.04) and combined treatment of ganciclovir and OG-L002 (p = 0.0003). In contrast, under similar conditions, neither ganciclovir nor OG-L002 suppressed EHV-1 infection in leukocytes. Differences between cell types, drug penetrance, or drug turnover, may have contributed to the distinct effects observed in this study. PMID- 29594156 TI - Affectionate Interactions of Cats with Children Having Autism Spectrum Disorder. AB - Mental and physical benefits of dogs have been reported for adults and children with special needs, but less is known about benefits of cats for children. A cat that can be held by a child could provide important therapeutic companionship for children with severe or less severe autism spectrum disorder (ASD) who otherwise may lack prosocial behaviors. Because relatively little is known about the behavior of cats around children, we conducted this study. Phase 1 gathered web survey data from families having an adult cat and a child with ASD (n = 64). In Phase 2, there were direct telephone interviews of parents having a child with severe ASD (n = 16) or less severe ASD (n = 11), or typical development (n = 17). From the Phase 1 web survey of families with ASD children (full range of severities), affectionate interactions of the cats with children were common. Most parents with ASD children volunteered positive comments regarding the cat, such as calming the child, being a soothing protector or a guardian. In the interviews in Phase 2, for all three groups, most parents characterized cats as at least moderately affectionate toward the child. However, cats living with severe ASD children were reported to exhibit less affection than those living with typically developing children or children with less severe ASD. A minority of cats in each group showed some aggression to the specified child; this was not elevated with ASD children. Responses suggested that the cats adopted as kittens were more affectionate and less aggressive to all categories of children than those adopted as adults. Overall, participants reported that ASD children's behaviors indicated that they valued the relationship with the cat, similar to typically developing children, pointing to the importance and potential usefulness of selecting affectionate and compatible cats for ASD children. PMID- 29594157 TI - Use of Nasotracheal Intubation during General Anesthesia in Two Ponies with Tracheal Collapse. AB - Ponies with tracheal collapse may have an increased anesthetic risk due to airway obstruction during induction and recovery. To our knowledge, there are no anesthetic descriptions of these patients, despite a reported 5.6% incidence and 77% mortality rate. Two Shetland ponies with tracheal collapse, a 12-year-old male (pony 1) and a 27-year-old female (pony 2), were referred for right eye enucleation due to a perforating corneal ulcer and severe recurrent uveitis, respectively. Pony 1 was stressed, had lung stridor and hyperthermia, and developed inspiratory dyspnea with handling. Radiography confirmed collapse of the entire trachea as well as inflammation of the lower airways. Corticosteroids and bronchodilators were administered by nebulization for 1 week before surgery. Pony 2 had a grade III/VI mitral murmur and a clinical history of esophageal obstructions and tracheal collapse requiring tracheostomy. Both ponies were premedicated with acepromazine and xylazine; anesthesia was induced with midazolam and ketamine. Nasotracheal intubation was performed in left lateral recumbency with extension of the neck and head and was guided by capnography. The nasotracheal tube consisted of two endotracheal tubes attached end-to-end to create a tube of adequate length and diameter. Pony 2 was orotracheally intubated during surgery and later reintubated with a nasotracheal tube. Anesthesia was maintained with isoflurane using volume-controlled ventilation. Analgesia was provided by a retrobulbar blockade with mepivacaine and lidocaine. Cardiovascular support consisted of lactated Ringer's solution and dobutamine. After surgery, the ponies were administered xylazine and supplemented with oxygen through the nasotracheal tube. Recovery was assisted by manual support of the head and tail. Successful extubation was achieved following butorphanol administration after approximately 1 h in standing position. Both ponies were discharged from the clinic a few days after surgery. PMID- 29594159 TI - Prepartum Maternal Behavior of Domesticated Cattle: A Comparison with Managed, Feral, and Wild Ungulates. AB - The event of giving birth is an essential part of animal production. In dairy cattle production, there are substantial economical and welfare-related challenges arising around the time of parturition, and hence increased focus on efficient management of the calving cow. Drawing on the research literature on prepartum maternal behavior, this review compares cattle to other members of the ungulate clade with the aim of understanding the biological basis of bovine prepartum behavior with main emphasis on dairy cows. Ultimately, this knowledge may be used in future development of housing systems and recommendations for the management of calving cows. Maternal prepartum behavior varies among species, but the final goal of ungulate mothers is the same: ensuring a calm parturition and optimal environment for the onset of postpartum maternal behavior by locating an appropriate birth site, with low risk of predators, disturbances and mistaken identity of offspring. Features of chosen birth sites vary among species and depend largely on the environment, as ungulate females display a considerable ability to adapt to their surroundings. However, within commercial housing conditions in dairy production, the animals' ability to adapt behaviorally appears to be challenged. Confinement alongside high stocking densities leave little room to express birth-site selection behavior, posing a high risk of agonistic social behavior, disturbances, and mismothering, as well as exposure to olfactory cues influencing both prepartum and postpartum maternal behavior. Dairy cows are thus exposed to several factors in a commercial calving environment, which may thwart their maternal motivations and influence their behavior. In addition, prepartum cattle may be more affected by olfactory cues than other ungulate species (e.g., sheep) because they are attracted to birth fluids already before calving. Hence, providing dairy cows with an environment where they can perform the maternal behavior they are motivated for, may aid a calm and secure calving and provide optimal surroundings for postpartum maternal behavior. Future research should focus on designing motivation-based housing systems allowing freedom to express prepartum maternal behavior and investigate in more detail the effects of the environment on the welfare of calving cows and their offspring. PMID- 29594158 TI - Effect of Melatonin Implants during the Non-Breeding Season on the Onset of Ovarian Activity and the Plasma Prolactin in Dromedary Camel. AB - To examine a possible control of reproductive seasonality by melatonin, continual release subcutaneous melatonin implants were inserted 4.5 months before the natural breeding season (October-April) into female camels (Melatonin-treated group). The animals were exposed to an artificial long photoperiod (16L:8D) for 41 days prior to implant placement to facilitate receptivity to the short-day signal that is expected with melatonin implants. The treated and control groups (untreated females) were maintained separately under outdoor natural conditions. Ovarian follicular development was monitored in both groups by transrectal ultrasonography and by plasma estradiol-17beta concentrations performed weekly for 8 weeks and then for 14 weeks following implant insertion. Plasma prolactin concentrations were determined at 45 and 15 days before and 0, 14, 28, 56, and 98 days after implant insertion. Plasma melatonin concentration was determined to validate response to the artificial long photoperiod and to verify the pattern of release from the implants. Results showed that the artificial long photoperiod induced a melatonin secretion peak of significantly (P < 0.05) shorter duration (about 2.5 h). Melatonin release from the implants resulted in higher circulating plasma melatonin levels during daytime and nighttime which persisted for more than 12 weeks following implants insertion. Treatment with melatonin implants advanced the onset of follicular growth activity by 3.5 months compared to untreated animals. Plasma estradiol-17beta increased gradually from the second week after the beginning of treatment to reach significantly (P < 0.01) higher concentrations (39.2 +/- 6.2 to 46.4 +/- 4.5 pg/ml) between the third and the fifth week post insertion of melatonin implants. Treatment with melatonin implants also induced a moderate, but significant (P < 0.05) suppressive effect on plasma prolactin concentration on the 28th day. These results demonstrate that photoperiod appears to be involved in dromedary reproductive seasonality. Melatonin implants may be a useful tool to manipulate seasonality and to improve reproductive performance in this species. Administration of subcutaneous melatonin implants during the transition period to the breeding season following an artificial signal of long photoperiod have the potential to advance the breeding season in camels by about 2.5 months. PMID- 29594160 TI - Job-Related Stress in Forensic Interviewers of Children with Use of Therapy Dogs Compared with Facility Dogs or No Dogs. AB - Sexually abused children providing essential testimony regarding crimes in forensic interviews now sometimes are provided facility dogs or therapy dogs for comfort. Facility dogs are extensively trained to work with forensic interviewers; when using therapy dogs in interviews, volunteers are the dog handlers. Interviews can impact child welfare workers' mental health causing secondary traumatic stress (STS). To investigate this stress, first data were gathered on stress retrospectively for when interviewers initially started the job prior to working with a dog, and then currently, from forensic interviewers using a facility dog, a therapy or pet dog, or no dog. These retrospective and secondary traumatic stress scale (STSS) data compared job stress among interviewers of children using: a certified, workplace facility dog (n = 16), a volunteer's trained therapy dog or the interviewer's pet dog (n = 13/3), or no dog (n = 198). Retrospective scores of therapy dog and no dog interviewers' stress were highest for the first interviewing year 1 and then declined. Extremely or very stressful retrospective scores differed among the three groups in year 1 (p < 0.038), and were significantly elevated for the therapy dog group as compared with the facility dog group (p < 0.035). All interviewing groups had elevated STSS scores; when compared with other healthcare groups that have been studied, sub-scores were especially high for Avoidance: a psychological coping mechanism to avoid dealing with a stressor. STSS scores differed among groups (p < 0.016), primarily due to Avoidance sub-scores (p < 0.009), reflecting higher Avoidance scores for therapy dog users than no dog users (p < 0.009). Facility dog users more consistently used dogs during interviews and conducted more interviews than therapy/pet dog users; both groups favored using dogs. Interviewers currently working with therapy dogs accompanied by their volunteers reported they had experienced heightened stress when they began their jobs; their high stress levels still persisted, indicating lower inherent coping skills and perhaps greater empathy among interviewers who later self-selected to work with therapy dogs. Results reveal extreme avoidant stress for interviewers witnessing children who are suffering and their differing coping approaches. PMID- 29594161 TI - Assessing the Economic Impact of Vaccine Availability When Controlling Foot and Mouth Disease Outbreaks. AB - Predictive models have been used extensively to assess the likely effectiveness of vaccination policies as part of control measures in the event of a foot and mouth disease (FMD) outbreak. However, the availability of vaccine stocks and the impact of vaccine availability on disease control strategies represent a key uncertainty when assessing potential control strategies. Using an epidemiological, spatially explicit, simulation model in combination with a direct cost calculator, we assessed how vaccine availability constraints may affect the economic benefit of a "vaccination-to-live" strategy during a FMD outbreak in Scotland, when implemented alongside culling of infected premises and dangerous contacts. We investigated the impact of vaccine stock size and restocking delays on epidemiological and economic outcomes. We also assessed delays in the initial decision to vaccinate, maximum daily vaccination capacity, and vaccine efficacy. For scenarios with conditions conducive to large outbreaks, all vaccination strategies perform better than the strategy where only culling is implemented. A stock of 200,000 doses, enough to vaccinate 12% of the Scottish cattle population, would be sufficient to maximize the relative benefits of vaccination, both epidemiologically and economically. However, this generates a wider variation in economic cost than if vaccination is not implemented, making outcomes harder to predict. The probability of direct costs exceeding L500 million is reduced when vaccination is used and is steadily reduced further as the size of initial vaccine stock increases. If only a suboptimal quantity of vaccine doses is initially available (100,000 doses), restocking delays of more than 2 weeks rapidly increase the cost of controlling outbreaks. Impacts of low vaccine availability or restocking delays are particularly aggravated by delays in the initial decision to vaccinate, or low vaccine efficacy. Our findings confirm that implementing an emergency vaccination-to-live strategy in addition to the conventional stamping out strategy is economically beneficial in scenarios with conditions conducive to large FMD outbreaks in Scotland. However, the size of the initial vaccine stock available at the start of the outbreak and the interplay with other factors, such as vaccine efficacy and delays in restocking or implementing vaccination, should be considered in making decisions about optimal control strategies for FMD outbreaks.

AB - Early and reliable diagnostic test is essential for effective therapy of lung cancer. Volatile organic compounds that are characteristic for cancer could serve as valuable biomarkers in cancer diagnosis. Both trace analytical and detection dog approaches give some evidence for the existence of such biomarkers. In this proof of concept, study dogs and trace analysis were implemented in combination to gain more information concerning cancer biomarkers. Two dogs were trained to distinguish between absorbed breath samples of lung cancer patients and healthy persons and succeeded with correct identification of patients with 9/9 and 8/9 and correct negative indications from of 8/10 and 4/10 samples from healthy individuals. A recent observational study found that breath samples from lung cancer patients showed an increase in 1-butanol, 2-butanone, 2-pentanone, and hexanal. Synthetic air samples were therefore fortified with these compounds and adsorbed to a fleece. Tested against breath samples from healthy probands, on presentation to the dogs these synthetic samples provoked an indication in three out of four samples. We were able to demonstrate that a combination of the natural nose of a dog and a trace analytic technique can be a valuable concept in the search for cancer biomarkers.

PMID- 29594164 TI - Upper Gastrointestinal Surgery: Robotic Surgery versus Laparoscopic Procedures for Esophageal Malignancy. AB - Background: The evolution of minimally invasive surgery (MIS) also extends to the field of esophageal surgery and has brought forth the development of several approaches of minimally invasive esophagectomy (MIE). Hybrid and total minimally invasive operative techniques have proven beneficial compared to open surgery and are currently evaluated against robotic-assisted minimally invasive esophagectomy (RAMIE). We aim to review the current literature regarding the position of MIE versus RAMIE. Methods: A systematic review of the relevant literature on minimally invasive esophageal surgery for cancer is presented. A PubMed search was carried out for the period of 1992-2018 with the following search terms: 'esophageal cancer', 'minimally invasive surgery', 'resection', 'transhiatal', 'transthoracic', 'MIE', 'hybrid', 'robotic resection', 'RAMIE', 'RATE'. Results: Hybrid and total minimally invasive operative techniques have proven beneficial, especially with regard to pulmonary complications, compared to open surgery. Oncologic outcomes appear equivalent between open and minimally invasive techniques. Currently, the position of RAMIE is being evaluated against other minimally invasive techniques. Conclusion: All minimally invasive techniques confer the expected reduction in perioperative morbidity compared to open surgery. However, MIS is still evolving with regard to specific technical challenges, especially anastomotic techniques. PMID- 29594165 TI - Lower Gastrointestinal Surgery: Robotic Surgery versus Laparoscopic Procedures. AB - Introduction: For a long time, the comprehensive application of minimally invasive techniques in lower gastrointestinal (GI) surgery was substantially impaired by inherent anatomical and technical complexities. Recently, several new techniques such as robotic operating platforms and transanal total mesorectal excision (taTME) have revolutionized the minimally invasive approach. This review aims to depict the current state of the art and evaluates the advantages and drawbacks in regard to perioperative outcome and quality of oncological resection. Methods: A systematic literature search was performed using the search terms 'colorectal cancer', 'rectal cancer', 'minimally invasive surgery', 'laparoscopic surgery', and 'robotic' to identify relevant studies reporting on robotic surgery (RS) either alone or in comparison to laparoscopic surgery (LS). Publications on taTME were analyzed separately. Results: 69 studies reporting on RS with a total of 20,872 patients, and 17 articles on taTME including 881 patients, were identified. Conclusion: Both RS and taTME can facilitate a minimally invasive approach for lower GI surgery in an increasing number of patients. Furthermore, combining both techniques might become an auspicious approach in selected patients; further prospective and randomized trials are needed to verify its benefits over conventional laTME. PMID- 29594166 TI - Robot-Assisted Transplant Surgery - Vision or Reality? A Comprehensive Review. AB - Minimally invasive surgery is standard procedure for many operations. Further refinements include the introduction of robotic surgery which is still an emerging field especially in laparoscopic surgery. Since the successful introduction of the da Vinci Robotic Surgical System, the robotic approach in organ transplantation has become of great interest in both the live donor organ retrieval and the recipient operation. Robotic surgery for kidney, liver, and pancreas transplantation is feasible. Over 700 donor nephrectomies and 100 kidney transplantations have been performed already, and robotic surgery is standard in a small number of pioneer centers; however, larger series and most importantly randomized controlled trials for the highest evidence are needed. Longer warm ischemia time and higher costs limit these procedures at the moment. PMID- 29594167 TI - First Experiences with the New Senhance(r) Telerobotic System in Visceral Surgery. AB - Until recently, robotic-assisted surgery has exclusively been connected to the name DaVinci(r). In 2016, a second robotic system, the Senhance(r), became available. To introduce the new robotic system into clinical routine, detailed team training and an integration program were useful. Within the first 6 months, 116 cases were performed with this system. The integration program intended to start with simple and well-standardized clinical cases. We chose inguinal hernia repair using the TAPP (transabdominal preperitoneal) technique as the starting procedure. Subsequently, we added upper gastrointestinal surgery and cholecystectomies, and colorectal procedures have since also been included. Initial experience with the Senhance system as the first installation in Germany shows that it is suitable for surgery in general and for visceral surgery in particular. The application is safe due to the unproblematically quick changeover to normal laparoscopy and easy to integrate due to the very short system integration times (docking times). Since it is a laparoscopic-based system, following an integration program will enable experienced laparoscopic surgeons to very quickly manage more complex procedures. Due to lower costs, introducing robotic surgery starting with simple and standardized procedures is more feasible. After the establishment of this second robotic system, future studies will have to specifically look at differences in surgical results and basic conditions of different robotic-assisted systems. This paper documents the decision-making process of a hospital towards the integration of a robotic system and the selection criteria used while also demonstrating the planning and execution process during the introduction of the system into clinical routine. PMID- 29594168 TI - Feasibility and Usefulness of a Joystick-Guided Robotic Scope Holder (Soloassist) in Laparoscopic Surgery. AB - Introduction: The Soloassist(r) system is a joystick-guided robotic scope holder. We evaluated the efficacy of Soloassist in laparoscopic surgery. Methods: We investigated operative time, blood loss, set-up time, length of hospital stay, and the number of participating surgeons in laparoscopic cholecystectomy cases before and after the introduction of Soloassist. Furthermore, we evaluated these factors in each group of 20 elective and emergency cholecystectomy cases by single surgeon after matching their background. To evaluate the performance level of operating Soloassist, we divided the operative field into three areas. Then we counted the frequency of energy device activation in initially 10 cases by a single surgical resident and observed its change. Results: The number of participating surgeons was significantly less and postoperative hospital days were fewer in the Soloassist group. There was no significant difference between set-up time and blood loss both in elective and emergency cases. The total number of energy device activations and that in the dangerous area decreased in accordance with the experience. Conclusion: Considering our results and previous reports, the combination use of an ideal active scope holder and a commercially available 3D scope is currently considered the best approach in laparoscopic surgery. In the near future, development of active scope holders might play an important role in laparoscopic surgery. PMID- 29594169 TI - Robotic Endoscopy. AB - Endoscopes extend the eyes of the physician into the patient's body. They are widely used in gastrointestinal (GI) diagnostics and minimally invasive surgery. Endoscopes can be classified into 3 types: rigid, flexible, and capsule endoscopes. Rigid and flexible endoscopes are traditionally held and manipulated by the physician to visualize the region of interest, while capsule endoscopes move passively along with the GI peristalsis. With the advancement of technology, robotic endoscopy has been increasingly developed and accepted. In this work, robotic endoscopy from 3 categories (robot-assisted rigid endoscopy, robot assisted flexible endoscopy, and active GI endoscopy including active flexible colonoscopy and active capsule endoscopy) is reviewed by PubMed search with the criteria ('Robotics' OR 'Robot') and ('Endoscopy' OR 'Endoscope').

PMID- 29594170 TI - Enhanced Visualization: From Intraoperative Tissue Differentiation to Augmented Reality. AB - Background: Optimal visualization of the operative field and methods that additionally provide supportive optical information form the basis for target directed and successful surgery. This article strives to give an overview of current enhanced visualization techniques in visceral surgery and to highlight future developments. Methods: The article was written as a comprehensive review on this topic and is based on a MEDLINE search and ongoing research from our own group and from other working groups. Results: Various techniques for enhanced visualization are described comprising augmented reality, unspecific and targeted staining methods, and optical modalities such as narrow-band imaging. All facilitate our surgical performance; however, due to missing randomized controlled studies for most of the innovations reported on, the available evidence is low. Conclusion: Many new visualization technologies are emerging with the aim to improve our perception of the surgical field leading to less invasive, target-oriented, and elegant treatment forms that are of significant benefit to our patients. PMID- 29594172 TI - Endoscopic Surveillance in Inflammatory Bowel Disease. AB - Introduction: Endoscopy is a key technique for the surveillance of patients with inflammatory bowel diseases (Crohn's disease (CD) and ulcerative colitis). Indication to perform endoscopy for surveillance includes assessment of response to therapy, postoperative surveillance, and surveillance for intraepithelial neoplasia. Methods: In addition to personal experience, a literature search was performed and the guidelines were consulted. Results and Conclusion: Endoscopy is the gold standard in the long-term assessment of mucosal healing and in the short term control of response to intensified therapy. For postoperative surveillance in CD, mucosal changes (as graded by the Rutgeerts score) are predictive of clinical recurrence. For neoplasia surveillance, virtual chromoendoscopy has not (yet) replaced conventional chromoendoscopy. Surveillance can be optimized by the use of high-definition endoscopes as well as (pan-)chromoendoscopy and requires time to scrutinize the mucosa. This approach seems to be superior to random biopsies. PMID- 29594173 TI - Acinar Cell Cystadenoma - a Rarity in Advanced von Hippel-Lindau Disease: A Case Report. AB - Background: Von Hippel-Lindau (VHL) disease may occur at various localisations which can be both intra- and extrapancreatic as well as challenging to diagnose by medical imaging. Case Report: A positron emission tomography/magnetic resonance imaging in a 40-year-old woman was performed to monitor a haemangioblastoma. Additionally, it showed findings which were considered to be a pancreatic neuroendocrine tumour (pNET) and retroumbilical metastasis. The suspected metastasis was laparoscopically resected; however, pathological evaluation did not lead to a clear categorisation. Consequently, the pancreatic head was resected in which a pNET and various acinar cell cystadenomas were found. Conclusion: Diagnostic and therapy of advanced VHL disease can be difficult; if in doubt, a surgical approach may establish clarity. PMID- 29594174 TI - Relationship between areas of cognitive functioning on the Mini-Mental State Examination and crash risk. AB - Previous studies have suggested that the pattern of cognitive impairment in crash involved older drivers is different from non-crash involved older drivers. This study assessed the relationship between seven areas of cognitive functioning (orientation to time, orientation to place, registration, attention and calculation, recall, language, and visual construction) on the Mini-Mental State Examination (MMSE) collected at baseline and rates of future crash involvement in a prospective population-based sample of older drivers. Motor vehicle collision involvement was obtained from the Alabama Department of Public Safety. Poisson regression was used to calculate crude and adjusted rate ratios (RR). Older drivers having difficulties in place orientation were more than 6 times (95% CI 1.90-19.86) more likely to be involved in a future crash (adjusted RR = 6.14, 95% confidence interval (CI) 1.90-19.86) and at-fault crash (adjusted RR=6.39, 95% CI 1.51-27.10). Impairment in the other cognitive areas was not associated with higher rates of crash or at-fault crash involvement. The findings were validated in an independent sample of high-risk older drivers and a similar pattern of results was observed. Spatial orientation impairment can help identify older drivers who are more likely to crash in the future. PMID- 29594175 TI - Multiple inflammasomes may regulate the interleukin-1-driven inflammation in protracted bacterial bronchitis. AB - Protracted bacterial bronchitis (PBB) in young children is characterised by prolonged wet cough, prominent airway interleukin (IL)-1beta expression and infection, often with nontypeable Haemophilus influenzae (NTHi). The mechanisms responsible for IL-1-driven inflammation in PBB are poorly understood. We hypothesised that the inflammation in PBB involves the NLRP3 and/or AIM2 inflammasome/IL-1beta axis. Lung macrophages obtained from bronchoalveolar lavage (BAL), peripheral blood mononuclear cells (PBMCs), blood monocytes and monocyte derived macrophages from patients with PBB and age-matched healthy controls were cultured in control medium or exposed to live NTHi. In healthy adult PBMCs, CD14+ monocytes contributed to 95% of total IL-1beta-producing cells upon NTHi stimulation. Stimulation of PBB PBMCs with NTHi significantly increased IL-1beta expression (p<0.001), but decreased NLRC4 expression (p<0.01). NTHi induced IL 1beta secretion in PBMCs from both healthy controls and patients with recurrent PBB. This was inhibited by Z-YVAD-FMK (a caspase-1 selective inhibitor) and by MCC950 (a NLRP3 selective inhibitor). In PBB BAL macrophages inflammasome complexes were visualised as fluorescence specks of NLRP3 or AIM2 colocalised with cleaved caspase-1 and cleaved IL-1beta. NTHi stimulation induced formation of specks of cleaved IL-1beta, NLRP3 and AIM2 in PBMCs, blood monocytes and monocyte-derived macrophages. We conclude that both the NLRP3 and AIM2 inflammasomes probably drive the IL-1beta-dominated inflammation in PBB. PMID- 29594176 TI - Scapular Dyskinesis in Young, Asymptomatic Elite Swimmers. AB - Background: Overhead athletes are at a greater risk of developing scapular dyskinesis (SD). Although swimming is considered an overhead sport, information regarding SD in these athletes is scarce. Purpose: To determine the prevalence of SD in young, asymptomatic elite swimmers. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 661 asymptomatic elite swimmers were enrolled in this study (344 male, 317 female; mean age, 15.83 +/- 2.20 years). Anthropometric characteristics, training routine, and stroke specialty were recorded. SD was assessed using a dynamic test consisting of an examination of the shoulder blades throughout synchronous forward flexion motion in the sagittal plane and was deemed to be either present or absent. Each movement was repeated 5 times. These evaluations were performed with athletes at rest, before any training or competition. Statistical analysis was performed. Results: SD was detected in 56 (8.5%) participants. Type I SD was the most common (46.5%); male participants were 2 times as likely to have SD as female participants (39 male, 17 female; P < .01). No correlation was found between the dominant limb and side affected (P = .258); rather, a correlation was found between the breathing side and side affected, in that swimmers with a preferred breathing side were more prone to develop SD in the opposite shoulder (P < .05). Swimmers involved in long distance races were found to have a greater risk of developing SD (P = .01). Conclusion: SD may be an asymptomatic condition in elite young swimmers and is present in 8.5% of these athletes. Early diagnosis may be useful for asymptomatic athletes with SD and to avoid its possible evolution to a symptomatic condition. PMID- 29594178 TI - Arthroscopic Management of Pigmented Villonodular Synovitis of the Hip in Children and Adolescents. AB - Background: Pigmented villonodular synovitis (PVNS) is a benign proliferative synovial disorder most commonly described to affect the knee in adults. Literature describing PVNS in the pediatric population is limited to 2 small case series and a handful of single-patient case reports. Within these studies, only 2 patients with PVNS of the hip are described. Purpose: To describe the presentation, management, and outcomes of a single-center series of pediatric patients with PVNS of the hip treated with arthroscopic synovectomy. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review of consecutive pediatric patients treated for PVNS at a single institution was performed. Inclusion criteria consisted of patients younger than 19 years with surgically treated PVNS of the hip. Results: Five pediatric patients with a mean age of 11.0 years were treated for PVNS of the hip from 2011 to 2016. The mean duration of symptoms from onset to surgical treatment was 247 days (range, 3-933 days). Upon review of magnetic resonance imaging (MRI) results, radiologists included PVNS in their differential in 3 patients. Seven surgeries were performed in 5 patients. All therapeutic procedures were arthroscopic synovectomies. Nodular PVNS was present in 4 patients, and diffuse disease was present in 1 patient. At a mean 32-month follow-up (range, 12-63 months), all patients were considered to be free of recurrence based on clinical examination and/or follow up MRI. Four patients were asymptomatic and returned to all of their previous sports activities. Conclusion: Young age at the time of diagnosis is a point to be highlighted in this cohort, and symptoms may be present for many months prior to diagnosis due to the failure to consider PVNS in children. Therefore, for patients with "atypical" presentations or lack of improvement with treatment for rheumatologic, bleeding, or infectious disorders, PVNS should be strongly considered. MRI with gradient echo sequences is the diagnostic imaging study of choice. One patient with diffuse involvement and preoperative degenerative changes showed progressive changes postoperatively. This type of PVNS may have a worse prognosis, but more diffuse cases are needed before the prognosis can be determined. Arthroscopic synovectomy following a timely diagnosis of PVNS produces good outcomes in nodular cases, with no evidence of symptomatic or radiographic disease persistence among these patients. PMID- 29594179 TI - Intervention Packages to Reduce the Impact of HIV and HCV Infections Among People Who Inject Drugs in Eastern Europe and Central Asia: A Modeling and Cost effectiveness Study. AB - Background: We evaluated the effectiveness and cost-effectiveness of interventions targeting hepatitis C virus (HCV) and HIV infections among people who inject drugs (PWID) in Eastern Europe/Central Asia. We specifically considered the needle-syringe program (NSP), opioid substitution therapy (OST), HCV and HIV diagnosis, antiretroviral therapy (ART), and/or new HCV treatment (direct acting antiviral [DAA]) in Belarus, Georgia, Kazakhstan, Republic of Moldova, and Tajikistan. Methods: We developed a deterministic dynamic compartmental model and evaluated the number of infections averted, costs, and incremental cost-effectiveness ratios (ICERs) of interventions. OST decreased frequencies of injecting by 85% and NSP needle sharing rates by 57%; ART was introduced at CD4 <350 and DAA at fibrosis stage >=F2 at a $2370 to $23 280 cost. Results: Increasing NSP+OST had a high impact on transmissions (infections averted in PWID: 42% in Tajikistan to 55% in Republic of Moldova for HCV; 30% in Belarus to 61% in Kazakhstan for HIV over 20 years). Increasing NSP+OST+ART was very cost-effective in Georgia (ICER = $910/year of life saved [YLS]), and was cost-saving in Kazakhstan and Republic of Moldova. NSP+OST+ART and HIV diagnosis was very cost-effective in Tajikistan (ICER = $210/YLS). Increasing the coverage of all interventions was always the most effective strategy and was cost effective in Belarus and Kazakhstan (ICER = $12 960 and $21 850/YLS); it became cost-effective/cost-saving in all countries when we decreased DAA costs. Conclusion: Increasing NSP+OST coverage, in addition to ART and HIV diagnosis, had a high impact on both epidemics and was very cost-effective and even cost saving. When HCV diagnosis was improved, increased DAA averted a high number of new infections if associated with NSP+OST. PMID- 29594177 TI - 2018 International Olympic Committee Consensus Statement on Prevention, Diagnosis, and Management of Pediatric Anterior Cruciate Ligament Injuries. AB - In October 2017, the International Olympic Committee hosted an international expert group of physical therapists and orthopaedic surgeons who specialize in treating and researching pediatric anterior cruciate ligament (ACL) injuries. The purpose of this meeting was to provide a comprehensive, evidence-informed summary to support the clinician and help children with ACL injury and their parents/guardians make the best possible decisions. Representatives from the following societies attended: American Orthopaedic Society for Sports Medicine; European Paediatric Orthopaedic Society; European Society for Sports Traumatology, Knee Surgery, and Arthroscopy; International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine; Pediatric Orthopaedic Society of North America; and Sociedad Latinoamericana de Artroscopia, Rodilla, y Deporte. Physical therapists and orthopaedic surgeons with clinical and research experience in the field and an ethics expert with substantial experience in the area of sports injuries also participated. This consensus statement addresses 6 fundamental clinical questions regarding the prevention, diagnosis, and management of pediatric ACL injuries. Injury management is challenging in the current landscape of clinical uncertainty and limited scientific knowledge. Injury management decisions also occur against the backdrop of the complexity of shared decision making with children and the potential long-term ramifications of the injury. PMID- 29594180 TI - Influence of Reported Penicillin Allergy on Mortality in MSSA Bacteremia. AB - Background: Penicillin allergy frequently impacts antibiotic choice. As beta lactams are superior to vancomycin in treating methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia, we examined the effect of reported penicillin allergy on clinical outcomes in patients with MSSA bacteremia. Methods: In this retrospective cohort study of adults with MSSA bacteremia admitted to a large tertiary care hospital, outcomes were examined according to reported penicillin allergy. Primary outcomes included 30-day and 90-day mortality rates. Multivariable regression models were developed to quantify the effect of reported penicillin allergy on mortality while adjusting for potential confounders. Results: From 2010 to 2015, 318 patients with MSSA bacteremia were identified. Reported penicillin allergy had no significant effect on adjusted 30 day mortality (odds ratio [OR], 0.73; 95% confidence interval [CI], 0.29-1.84; P = .51). Patients with reported penicillin allergy were more likely to receive vancomycin (38% vs 11%, P < .01), but a large number received cefazolin regardless of reported allergy (29 of 66, 44%). Mortality rates were highest among nonallergic patients receiving vancomycin (22.6% vs 7.4% for those receiving beta-lactams regardless of reported allergy, P < .01). In multivariable analysis, beta-lactam receipt was most strongly associated with survival (OR, 0.26; 95% CI, 0.12-0.54). Conclusions: Reported penicillin allergy had no significant effect on 30- or 90-day mortality. Non-penicillin-allergic patients receiving vancomycin for treatment of MSSA bacteremia had the highest mortality rates overall. Receipt of a beta-lactam was the strongest predictor of survival. These results underscore the importance of correct classification of patients with penicillin allergy and appropriate treatment with a beta-lactam when tolerated. PMID- 29594181 TI - Predicting malignant nodules by fusing deep features with classical radiomics features. AB - Lung cancer has a high incidence and mortality rate. Early detection and diagnosis of lung cancers is best achieved with low-dose computed tomography (CT). Classical radiomics features extracted from lung CT images have been shown as able to predict cancer incidence and prognosis. With the advancement of deep learning and convolutional neural networks (CNNs), deep features can be identified to analyze lung CTs for prognosis prediction and diagnosis. Due to a limited number of available images in the medical field, the transfer learning concept can be helpful. Using subsets of participants from the National Lung Screening Trial (NLST), we utilized a transfer learning approach to differentiate lung cancer nodules versus positive controls. We experimented with three different pretrained CNNs for extracting deep features and used five different classifiers. Experiments were also conducted with deep features from different color channels of a pretrained CNN. Selected deep features were combined with radiomics features. A CNN was designed and trained. Combinations of features from pretrained, CNNs trained on NLST data, and classical radiomics were used to build classifiers. The best accuracy (76.79%) was obtained using feature combinations. An area under the receiver operating characteristic curve of 0.87 was obtained using a CNN trained on an augmented NLST data cohort. PMID- 29594182 TI - Model-based quantitative optical biopsy in multilayer in vitro soft tissue models for whole field assessment of nonmelanoma skin cancer. AB - Optical techniques such as fluorescence and diffuse reflectance spectroscopy are proven to have the potential to provide tissue discrimination during the development of malignancies and hence treated as potential tools for noninvasive optical biopsy in clinical diagnostics. Quantitative optical biopsy is challenging and hence the majority of the existing strategies are based on a qualitative assessment of the concerned tissue. Light-tissue interaction models as well as precise optical phantoms can greatly help in the former and here we present a pilot study to assess the optical properties of a multilayer tissue specific optical phantom with the help of a database generated using multilayer Monte Carlo (MCML) models. A set of optical models mimicking the properties of actual and diseased conditions of tissues associated with nonmelanoma skin cancer (NMSC) were devised and MCML simulations of fluorescence and diffuse reflectance were performed on these models to generate the spectral signature of identified biomarkers of NMSC such as hemoglobin, flavin adenine dinucleotide, and collagen. A model library was generated and with the extracted features from modeled spectra, classification of normal and NMSC conditions were tested using the [Formula: see text]-nearest neighbor (KNN) classifier. Using an in-house assembled scan-based automated bimodal spectral imaging system with reflectance and fluorescence modalities of operation, a layered, thin, tissue equivalent phantom, fabricated with controlled optical properties mimicking normal and NMSC conditions were tested. The spectral signatures corresponding to the NMSC biomarkers were acquired from this phantom and extracted features from the spectra were tested using the KNN classifier and classification accuracy of 100% was achieved. For further quantitative analysis, the experimental and simulated spectra were compared with respect to the light intensity at the emission peak or absorption dips, spectral line width, and average intensity over a range of wavelength of interest and observed to be analogous within specified and systematic error limits. This methodology is expected to give a better quantitative approach for estimation of tissue properties by correlating the experimental and simulated data. PMID- 29594183 TI - Patient-specific cardiac phantom for clinical training and preprocedure surgical planning. AB - Minimally invasive mitral valve repair procedures including MitraClip(r) are becoming increasingly common. For cases of complex or diseased anatomy, clinicians may benefit from using a patient-specific cardiac phantom for training, surgical planning, and the validation of devices or techniques. An imaging compatible cardiac phantom was developed to simulate a MitraClip(r) procedure. The phantom contained a patient-specific cardiac model manufactured using tissue mimicking materials. To evaluate accuracy, the patient-specific model was imaged using computed tomography (CT), segmented, and the resulting point cloud dataset was compared using absolute distance to the original patient data. The result, when comparing the molded model point cloud to the original dataset, resulted in a maximum Euclidean distance error of 7.7 mm, an average error of 0.98 mm, and a standard deviation of 0.91 mm. The phantom was validated using a MitraClip(r) device to ensure anatomical features and tools are identifiable under image guidance. Patient-specific cardiac phantoms may allow for surgical complications to be accounted for preoperative planning. The information gained by clinicians involved in planning and performing the procedure should lead to shorter procedural times and better outcomes for patients. PMID- 29594184 TI - Photoacoustic-based catheter tracking: simulation, phantom, and in vivo studies. AB - Catheters are commonly used in many procedures and tracking and localizing them is critical to patient safety and surgical success. The standard of care for catheter tracking is with the use of fluoroscopy. Alternatives using conventional tracking technologies such as electromagnetic trackers have been previously explored. This work explores the use of an emerging imaging modality, photoacoustics, as a means for tracking. A piezoelectric (PZT) sensor is placed at the tip of the catheter, allowing it to receive the acoustic signals generated from photoacoustic markers due to the photoacoustic effect. The locations of these photoacoustic markers are determined by a stereo-camera and the received acoustic signals are converted into distances between the PZT element and the photoacoustic markers. The location of the PZT sensor can be uniquely determined following a multilateration process. This work validates this photoacoustic tracking method in phantom, simulation, and in vivo scenarios using metrics including reconstruction precision, relative accuracy, estimated accuracy, and leave-out accuracy. Submillimeter tracking results were achieved in phantom experiments. Simulation studies evaluated various physical parameters relating to the photoacoustic source and the PZT sensor. In vivo results showed feasibility for the eventual deployment of this technology. PMID- 29594185 TI - Ab Initio Optimized Effective Potentials for Real Molecules in Optical Cavities: Photon Contributions to the Molecular Ground State. AB - We introduce a simple scheme to efficiently compute photon exchange-correlation contributions due to the coupling to transversal photons as formulated in the newly developed quantum-electrodynamical density-functional theory (QEDFT).1-5 Our construction employs the optimized-effective potential (OEP) approach by means of the Sternheimer equation to avoid the explicit calculation of unoccupied states. We demonstrate the efficiency of the scheme by applying it to an exactly solvable GaAs quantum ring model system, a single azulene molecule, and chains of sodium dimers, all located in optical cavities and described in full real space. While the first example is a two-dimensional system and allows to benchmark the employed approximations, the latter two examples demonstrate that the correlated electron-photon interaction appreciably distorts the ground-state electronic structure of a real molecule. By using this scheme, we not only construct typical electronic observables, such as the electronic ground-state density, but also illustrate how photon observables, such as the photon number, and mixed electron photon observables, for example, electron-photon correlation functions, become accessible in a density-functional theory (DFT) framework. This work constitutes the first three-dimensional ab initio calculation within the new QEDFT formalism and thus opens up a new computational route for the ab initio study of correlated electron-photon systems in quantum cavities.

AB - Metasurfaces impart phase discontinuities on impinging electromagnetic waves that are typically limited to 0-2pi. Here, we demonstrate that multiresonant metasurfaces can break free from this limitation and supply arbitrarily large, tunable time delays over ultrawide bandwidths. As such, ultrathin metasurfaces can act as the equivalent of thick bulk structures by emulating the multiple geometric resonances of three-dimensional systems that originate from phase accumulation with effective material resonances implemented on the surface itself via suitable subwavelength meta-atoms. We describe a constructive procedure for defining the required sheet admittivities of such metasurfaces. Importantly, the proposed approach provides an exactly linear phase response so that broadband pulses can experience the desired group delay without any distortion of the pulse shape. We focus on operation in reflection by exploiting an antimatching condition, satisfied by interleaved electric and magnetic Lorentzian resonances in the surface admittivities, which completely zeroes out transmission through the metasurface. As a result, the proposed metasurfaces can perfectly reflect a broadband pulse imparting a prescribed group delay. The group delay can be tuned by modifying the implemented resonances, thus opening up diverse possibilities in the temporal applications of metasurfaces.

AB - Skeletal muscle provides the contractile force necessary for movement, swallowing, and breathing and, consequently, is necessary for survival. Skeletal muscle cells are unique in that they are extremely large cells containing thousands of nuclei. These nuclei must all work in concert to maintain skeletal muscle function and thereby maintain life. The nucleus is a major site of signaling integration and gene expression regulation. However, examining nuclear processes in skeletal muscle can be difficult because myonuclei are challenging to isolate. We optimized a protocol to purify myonuclei from whole muscle tissue using ultracentrifugation over a discontinuous sucrose gradient to separate the nuclear fraction. We used these purified nuclei for downstream applications including flow cytometry and mass spectrometry. We used this method to compare the myonuclear proteome of young and old mouse hindlimb muscles (Cutler et al., 2017). This protocol may be applied to isolating myonuclei for a variety of downstream analyses such as flow cytometry, microscopy, Western blot, and proteomics. PMID- 29594188 TI - Dual-sided Voltage-sensitive Dye Imaging of Leech Ganglia. AB - In this protocol, we introduce an effective method for voltage-sensitive dye (VSD) loading and imaging of leech ganglia as used in Tomina and Wagenaar (2017). Dissection and dye loading procedures are the most critical steps toward successful whole-ganglion VSD imaging. The former entails the removal of the sheath that covers neurons in the segmental ganglion of the leech, which is required for successful dye loading. The latter entails gently flowing a new generation VSD, VF2.1(OMe).H, onto both sides of the ganglion simultaneously using a pair of peristaltic pumps. We expect the described techniques to translate broadly to wide-field VSD imaging in other thin and relatively transparent nervous systems.

AB - Pay-for-performance (P4P) programs have become a popular policy tool aimed at improving health care quality. We analyze how incentive design affects quality improvements in the nursing home setting, where several state Medicaid agencies have implemented P4P programs that vary in incentive structure. Using the Minimum Data Set and the Online Survey, Certification, and Reporting data from 2001 to 2009, we examine how the weights put on various performance measures that are tied to P4P bonuses, such as clinical outcomes, inspection deficiencies, and staffing levels, affect improvements in those measures. We find larger weights on clinical outcomes often lead to larger improvements, but small weights can lead to no improvement or worsening of some clinical outcomes. We find a qualifier for P4P eligibility based on having few or no severe inspection deficiencies is more effective at decreasing inspection deficiencies than using weights, suggesting simple rules for participation may incent larger improvement. PMID- 29594190 TI - Complex Pulmonary Aspergilloma: Surgical Challenges in a Third World Setting. AB - Background: Surgery for pulmonary aspergilloma (PA), especially complex forms, is greatly challenging in a resource-poor setting such as Cameroon. We report our experience of surgical management of PA in this environment. Method: We prospectively assessed patients who underwent surgery for PA from January 2012 to May 2015, at the University Hospital Center of Yaounde. Records were reviewed for demographics, history and physical examinations, radiological findings, surgical procedures, and outcomes. The study has received approval from the institutional ethics committees. Results: In total, 20 patients (17 males and 3 females (sex ratio, 5.66); mean age, 30 years; range, 23-65 years) with a past history of tuberculosis were assessed. The median follow-up was 21.5 months. The primary symptom was hemoptysis, followed by cough and chest pain. All patients underwent surgical treatment and lung resection. Postoperative complications (bleeding, air leak, empyema, and severe anemia) occurred in 4 patients and 1 patient died. Although 3 patients were lost to follow-up, the survival rate was 80% with improvement of the preoperative symptoms. Conclusion: Although surgery for complex aspergilloma is very challenging in environments such as ours, we believe that it is the best treatment modality for symptomatic diseases in our setting. PMID- 29594191 TI - Nutrition Education in Internal Medicine Residency Programs and Predictors of Residents' Dietary Counseling Practices. AB - Background: Although physicians are expected to provide dietary counseling for patients with cardiovascular (CV) risk factors such as hypertension, hyperlipidemia, diabetes, and obesity, nutrition education in graduate medical education remains limited. Few studies have recently examined nutrition education and dietary counseling practices in Internal Medicine (IM) residency training. Objectives: To conduct a contemporary assessment of outpatient nutrition education in IM residency programs in the United States, identify predictors of residents' dietary counseling practices for CV risk factors, and identify barriers for educators in providing nutrition education and barriers for residents in counseling patients. Design: Cross-sectional anonymous surveys were completed by IM program directors (PDs) and residents throughout the United States. Linear regression was used to examine the association between the amount of nutrition education received and the number of instruction methods used by the residents and frequency of residents' dietary counseling for patients with CV risk factors. Key Results: A total of 40 educators (PDs and ambulatory/primary care PDs) and 133 residents across the United States responded to the survey. About 61% of residents reported having very little or no training in nutrition. Nutrition education in residency, both the amount of education (beta = 0.20, P = .05) and the number of instruction methods used (beta = 0.26, P = .02), predicted frequency of residents' dietary counseling practices independent of nutrition education in medical school, which was also significantly associated with counseling (beta = 0.20, P = .03). Residents' total fruit and vegetable intake likewise predicted frequency of counseling (beta = 0.24, P < .001). Low perceived faculty expertise was a major barrier for educators and was associated with lower level of provided nutrition education (r = -.33, P = .04). Low resident and low perceived clinic preceptors' interests in nutrition were also associated with lower frequency of residents' dietary counseling (r = -.19, P = .04; r = -.18, P = .05). Conclusions: The provision of nutrition education in IM residency programs and IM residents' dietary counseling for patients need to be systematically assessed nationally. This study's preliminary findings suggest that multimodal nutrition education in IM residency and better resident dietary habits are associated with higher frequency of dietary counseling for patients. Lack of faculty expertise and low faculty and resident interests in patient counseling need to be addressed perhaps by mandating nutrition education in graduate and continuing medical education. PMID- 29594193 TI - Expression of intrahepatic CD3, CD4, and CD8 T cells in biliary atresia. AB - Aim of the study: Assessment of the expression of cluster of differentiation (CD)3, CD4, and CD8 T cells in biliary atresia (BA) cases in comparison to neonatal cholestasis other than BA. Material and methods: This study included 79 patients: 34 patients with BA (BA group) and 35 patients with neonatal cholestasis due to causes other than BA (cholestasis group), and 10 normal liver donor as a control group. Immunohistochemical staining or CD3, CD4, and CD8 T cells in liver tissues for the 3 groups were evaluated. Results: Presence of clay stool, high gamma-glutamyl transferase levels, thrombocytosis, and non contractibility of the gallbladder was the main clinical, laboratory, and radiological findings, distinguishing BA from other disorders causing neonatal cholestasis. Portal ductular proliferation, bile plugs in portal ductules, and advanced grades of fibrosis were more predominant in liver biopsy specimens of BA patients. The CD3+, CD4+, and CD8+ expression in patients with BA were significantly higher than in both cholestasis and control groups, while it was comparable in the cholestasis and control groups, with cutoff values of 25, 12, and 2.5 cells/portal tract, respectively, differentiating between BA and cholestatic patients. Conclusions: Immune-mediated destruction of bile ducts is incriminated in the pathogenesis of BA. Lymphocytic infiltrate in portal tract is primarily composed of CD3, CD4, and CD8 T cells. Immunostaining of liver tissue for CD3, CD4, and CD8 T cells can help in ensuring diagnosis of BA. PMID- 29594192 TI - The influence of NAFLD on the risk of atherosclerosis and cardiovascular diseases. AB - Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in developed countries and is associated with obesity, dyslipidaemia, diabetes, and metabolic syndrome. Atherosclerosis and cardiovascular diseases are also highly prevalent in this group of patients, due to the presence of shared risk factors. The incidences of coronary artery calcification, hypertension, aortic valve sclerosis, diastolic dysfunction, atherosclerotic plaques, and increased carotid intima-media thickness were more common in patients with NAFLD than in those without. The present paper reviews the medical literature concerning the association between NAFLD and cardiovascular events. PMID- 29594194 TI - The epidemiology of hepatocellular cancer in Poland. AB - Introduction: This article summarize the available data on hepatocellular carcinoma (HCC) epidemiology in Poland. Data regarding the HCC incidence rate are divergent. Statistical data presented by NFZ appear more credible in that matter than data published by the Polish Oncology Center (POC). Material and methods: The analysis included data from the Polish Bibliography Database (GBL), the Polish National Health Fund Institution (NFZ), the scientific paper "Malignant neoplasms in Poland" issued by POC and the central liver transplant registry maintained by the Polish transplant coordinating center "Poltransplant" (2010 2015). Results: Data regarding the HCC incidence rate are divergent. Statistical data presented by NFZ appear more credible in that matter than data published by POC. Conclusions: The occurrence of HCC in Poland is at the average European level and is similarly rising. The incidence rate is underestimated. It is due to faulty epidemiology data collection techniques. The highest risk group comprises men over the age of 50 with concomitant liver cirrhosis. The most common HCC etiology is HCV infection. PMID- 29594195 TI - Effects of infection on post-transplant outcomes: living versus deceased donor liver transplants. AB - Introduction: Post-transplant infections have been studied widely but data on comparisons of deceased donor liver transplants (DDLT) and living donor liver transplants (LDLT), type and timings of infections, and their relations to outcomes are not explored. Material and methods: We analysed data from 612 participants of the Adult-to-Adult Living Donor Liver Transplantation Study (A2ALL), a retrospective data set of LDLT and DDLT. We compared the type and timing of the first post-transplant infection in relation to transplant outcomes between the two groups. Results: Out of 611 patients, 24.5% experienced the first post-transplant infection, the majority of which were bacterial (35.3%), followed by fungal (11%) and viral infections (4.2%). There was no significant difference in the rate, type or timing of infection between LDLT and DDLT. Patients with late (> 1 year) first infection were 1.8 times more likely to die (95% CI: 1.12 2.98, p = 0.015) and 9 times more likely to have graft failures (95% CI: 3.26 24.8, p < 0.001). DDLT recipients who experienced bacterial infection had a significantly lower survival rate compared to LDLT recipients (p < 0.001). Conclusions: Late infection is associated with lower survival in both DDLT and LDLT. Bacterial infection might be more detrimental for DDLT than LDLT. Late infection should be managed aggressively to improve outcomes. PMID- 29594196 TI - Evaluation of serum interleukin-10 levels in hepatocellular carcinoma patients: a systematic review and meta-analysis. AB - Aim of the study: This meta-analysis aimed to evaluate serum IL-10 levels in HCC patients. Material and methods: The three databases PubMed, Scopus and Web of Science were checked on July 2017 for assessment of IL-10 levels in hepatocellular carcinoma (HCC) patients compared with healthy controls in publications with an English abstract. A random-effect meta-analysis was performed using mean difference (MD) and 95% confidence intervals (CIs). Also, publication bias was evaluated through funnel plot analysis with the Begg's and Egger's tests. Results: Out of 171 studies searched in the databases, nine studies were included in the meta-analysis. The pooled analysis with continuous data concluded that IL-10 level in the patients was significantly higher than the controls (MD = 6.96; 95% CI = 4.91-9.01; p < 0.00001), in the HCC patients was significantly higher than the cirrhotic patients (MD = 2.92; 95% CI = 0.72-5.12; p = 0.009), and was similar in the HCC patients compared with the patients with hepatitis (MD = 3.91; 95% CI = -4.25-12.07; p = 0.35). Conclusion: The increased IL-10 levels in the HCC patients compared with the cirrhotic patients and the healthy controls may show a significant role of this cytokine in the elevated risk of HCC, but the lack of significant difference in the levels between HCC and hepatitis makes it an unreliable tumor marker in the latter. PMID- 29594197 TI - Cannulation in patients with large periampullary diverticulum using SpyBite miniforceps. AB - Introduction: Cannulation is difficult in patients with periampullary diverticulum (PAD). The described success rate varies from 61% to 95.4%. Material and methods: Four cases with PAD in which, despite repeated attempts, we were unable to locate the papilla and cannulate. To overcome this difficulty, we used SpyBite forceps (Boston Scientific) to pull out the papillary orifice and then perform the cannulation using a sphincterotome introduced through the same working channel. Results: This method reduced the time required for cannulation. In all four of our cases, we had 100% success in cannulation. Conclusions: Use of SpyBite miniforceps in difficult cannulations in patients with PAD is useful and has an excellent success rate. PMID- 29594198 TI - Hepatic infarction and acute pancreatitis: a case report and review of the literature. AB - Hepatic infarction is rare due to the unique dual hepatic blood supply from the hepatic artery and the portal vein. Herein, we report a case of hepatic infarction that occurred as a complication of acute pancreatitis. The patient was a 58-year-old male with past medical history of chronic alcoholism, who presented with epigastric abdominal pain, nausea, and vomiting. Hepatic infarction was diagnosed with computed tomography of the abdomen and pelvis without contrast, which revealed suspicion of splenic vein thrombosis and peripancreatic fat stranding along with a wedge-shaped, peripheral hypo density in the right hepatic lobe with typical morphology for hepatic infarction. PMID- 29594199 TI - Hemospray for recurrent esophageal band ulcer bleeding. AB - Rebleeding after initially successful endoscopic variceal ligation (EVL) occurs in 20-60% of patients, most commonly from band ulcers, and is associated with 20 50% mortality. Although band ulcer bleeding has been treated in a number of different ways, no single therapeutic intervention has shown a clear benefit. Hemospray (Cook Medical, Winston-Salem, North Carolina, USA) is a relatively new non-contact hemostatic modality used in the management of bleeding peptic ulcers. It is a nano-powder that can be sprayed over a larger mucosal area. Here we describe a patient with end stage liver disease who presented with recurrent bleeding from a deep esophageal ulcer following band ligation and sclerotherapy, effectively managed with multiple sessions of Hemospray. PMID- 29594200 TI - Structural alterations by five disease-causing mutations in the low-pH conformation of human dihydrolipoamide dehydrogenase (hLADH) analyzed by molecular dynamics - Implications in functional loss and modulation of reactive oxygen species generation by pathogenic hLADH forms. AB - Human dihydrolipoamide dehydrogenase (hLADH) is a flavoenzyme component (E3) of the human alpha-ketoglutarate dehydrogenase complex (alpha-KGDHc) and few other dehydrogenase complexes. Pathogenic mutations of hLADH cause severe metabolic diseases (atypical forms of E3 deficiency) that often escalate to cardiological or neurological presentations and even premature death; the pathologies are generally accompanied by lactic acidosis. hLADH presents a distinct conformation under acidosis (pH 5.5-6.8) with lower physiological activity and the capacity of generating reactive oxygen species (ROS). It has been shown by our laboratory that selected pathogenic mutations, besides lowering the physiological activity of hLADH, significantly stimulate ROS generation by hLADH, especially at lower pH, which might play a role in the pathogenesis of E3-deficiency in respective cases. Previously, we generated by molecular dynamics (MD) simulation the low-pH hLADH structure and analyzed the structural changes induced in this structure by eight of the pathogenic mutations of hLADH. In the absence of high resolution mutant structures these pieces of information are crucial for the mechanistic investigation of the molecular pathogeneses of the hLADH protein. In the present work we analyzed by molecular dynamics simulation the structural changes induced in the low-pH conformation of hLADH by five pathogenic mutations of hLADH; the structures of these disease-causing mutants of hLADH have never been examined before. PMID- 29594201 TI - Association of lung fluorodeoxyglucose uptake with radiation pneumonitis after concurrent chemoradiation for non-small cell lung cancer. AB - Background: Increased uptake of fluorodeoxyglucose (FDG) by lung tissue could reflect inflammatory changes related to radiation pneumonitis (RP). In this secondary analysis of a clinical trial, we examined potential associations between posttreatment lung FDG uptake and RP severity in patients with non-small cell lung cancer (NSCLC) for up to 12 months after concurrent chemoradiation (CRT). Methods: Subjects were 152 patients with NSCLC who had received concurrent CRT as part of the prospective trial NCT00915005. The following lung FDG variables were evaluated after CRT: maximum, mean, and peak standardized uptake values (SUVmax, SUVmean, SUVpeak) and global lung glycolysis (GLG; lung SUVmean * lung volume). RP severity was scored with the Common Terminology Criteria for Adverse Events v3.0. Results: Significant associations were noted between PET findings and RP severity at 1-6 months (all P < 0.05), but not at 7-12 months after therapy (all P > 0.05). Lung FDG uptake at 1-3 months after treatment predicted later development of grade >=2 RP (all P < 0.05), with cutoff values as follows: 4.54 for SUVmax, 3.69 for SUVpeak, 0.78 for SUVmean, and 2295 for GLG. Conclusions: Lung FDG uptake correlated significantly with RP severity during the first 6 months after CRT. The cutoff values seem clinically meaningful for identifying patients at risk of developing RP after such therapy. PMID- 29594202 TI - Time to surgery and pathologic complete response after neoadjuvant chemoradiation in rectal cancer: A population study on 2094 patients. AB - Background: To retrospectively evaluate the difference in terms of pathologic complete response (pCR) according to time elapsed between chemoradiation (CRT) and total mesorectal excision (TME) on a large unselected real-life dataset of locally advanced rectal cancer (LARC) patients. Methods: A multicentre retrospective cohort study of LARC patients from 21 Italian Radiotherapy Institutions was performed. Patients were stratified into 3 different time intervals from CRT. The 1st group included 300 patients who underwent TME within 6 weeks, the 2nd 1598 patients (TME within 7-12 weeks) and the 3rd 196 patients (TME within 13 or more weeks after CRT), respectively. Results: Data on 2094 LARC patients treated between 1997 and 2016 were considered suitable for analysis. Overall, 578 patients had stage II while 1516 had stage III histological proven invasive rectal adenocarcinoma. A CRT schedule of one agent (N = 1585) or 2-drugs (N = 509) was administered. Overall, pCR was 22.3% (N = 468 patients). The proportion of patients achieving pCR with respect to time interval was, as follows: 12.6% (1st group), 23% (2nd group) and 31.1% (3rd group) (p < 0.001), respectively. The pCR relative risk comparison of 2nd to 1st group was 1.8, while 3rd to 2nd group was 1.3. Moreover, between the 3rd and 1st group, a pCR relative risk of 2.4 (p < 0.01) was noted. At univariate analysis, clinical stage III (p < 0.001), radiotherapy dose >5040 cGy (p = 0.002) and longer interval (p < 0.001) were significantly correlated to pCR. The positive impact of interval (p < 0.001) was confirmed at multivariate analysis as the only correlated factor. Conclusion: We confirmed on a population-level that lengthening the interval (>13 weeks) from CRT to surgery improves the pathological response (pCR and pathologic partial response; pPR) in comparison to historic data. Furthermore, radiotherapy dose >5040 cGy and two drugs chemotherapy correlated with pPR rate. PMID- 29594203 TI - Association between cumulative radiation dose, adverse skin reactions, and changes in surface hemoglobin among women undergoing breast conserving therapy. AB - Introduction: Radiation therapy is crucial to effective cancer treatment. Modern treatment strategies have reduced possible skin injury, but few clinical studies have addressed the dose relationship between radiation exposure and skin reaction. This prospective clinical study analyzes skin oxygenation/perfusion in patients undergoing fractionated breast conserving therapy via hyperspectral imaging (HSI). Methods: Forty-three women undergoing breast conserving therapy were enrolled in this study. Optically stimulated luminescent dosimeters (OSLDs) measured radiation exposure in four sites: treatment breast, lumpectomy scar, medial tattoo and the control breast. The oxygenation/perfusion states of these sites were prospectively imaged before and after each treatment fraction with HSI. Visual skin reactions were classified according to the RTOG system. Results: 2753 observations were obtained and indicated a dose-response relationship between radiation exposure and oxygenated hemoglobin (OxyHb) after a 600 cGy cumulative dose threshold. There was a relatively weak association between DeoxyHb and radiation exposure. Results suggest strong correlations between changes in mean OxyHb and skin reaction as well as between radiation exposure and changes in skin reaction. Conclusion: HSI demonstrates promise in the assessment of skin dose as well as an objective measure of skin reaction. The ability to easily identify adverse skin reactions and to modify the treatment plan may circumvent the need for detrimental treatment breaks. PMID- 29594204 TI - Infrastructure and distributed learning methodology for privacy-preserving multi centric rapid learning health care: euroCAT. AB - Machine learning applications for personalized medicine are highly dependent on access to sufficient data. For personalized radiation oncology, datasets representing the variation in the entire cancer patient population need to be acquired and used to learn prediction models. Ethical and legal boundaries to ensure data privacy hamper collaboration between research institutes. We hypothesize that data sharing is possible without identifiable patient data leaving the radiation clinics and that building machine learning applications on distributed datasets is feasible. We developed and implemented an IT infrastructure in five radiation clinics across three countries (Belgium, Germany, and The Netherlands). We present here a proof-of-principle for future 'big data' infrastructures and distributed learning studies. Lung cancer patient data was collected in all five locations and stored in local databases. Exemplary support vector machine (SVM) models were learned using the Alternating Direction Method of Multipliers (ADMM) from the distributed databases to predict post radiotherapy dyspnea grade [Formula: see text]. The discriminative performance was assessed by the area under the curve (AUC) in a five-fold cross-validation (learning on four sites and validating on the fifth). The performance of the distributed learning algorithm was compared to centralized learning where datasets of all institutes are jointly analyzed. The euroCAT infrastructure has been successfully implemented in five radiation clinics across three countries. SVM models can be learned on data distributed over all five clinics. Furthermore, the infrastructure provides a general framework to execute learning algorithms on distributed data. The ongoing expansion of the euroCAT network will facilitate machine learning in radiation oncology. The resulting access to larger datasets with sufficient variation will pave the way for generalizable prediction models and personalized medicine. PMID- 29594205 TI - Effect of heterogeneous radio sensitivity on the survival, alpha beta ratio and biologic effective dose calculation of irradiated mammalian cell populations. AB - It is demonstrated that the surviving fraction of a population of cells with heterogeneous radio sensitivity, like that composing most malignant tumors, conforms to a different linear quadratic survival relation for dose less than about 3-5 Gy and dose greater than about 7-9 Gy. In the intermediate range of dose the survival relation for the population, as a whole, is not linear quadratic. Consequently, the value of the alpha beta ratio and the associated biologically effective dose calculation are different for the low and high dose range for most malignant tumors. Normal tissue cell populations responsible for organ function also have heterogeneous radio sensitivity, though to less degree than most malignant tumors. Consequently, the alpha beta ratio and associated biologically effective dose calculation related to the development of some acute early and chronic late developing radiation injuries are not the same in the low and high dose range. Variance of the distribution of alpha of a heterogeneous cell population lowers the effective value of the quadratic survival constant beta of the population, as a whole, and increases the alpha/beta ratio in the low dose range. Heterogeneous appearance of tumor cells (pleomorphism) and necrosis on biopsy or imaging studies reflect heterogeneity of the radio sensitivity of the cells. Greater heterogeneity implies a tendency to higher alpha/beta ratio. This may furnish a clinically accessible way to estimate a value of the alpha/beta ratio specific to an individual patient and tumor. PMID- 29594206 TI - Definitive radiation therapy for hepatocellular carcinoma with portal vein tumor thrombus. AB - Background: The purpose of this study is to review the results of radiation therapy (RT) for hepatocellular carcinoma (HCC) with portal venous tumor thrombus (PVTT) in a Western patient population. Methods: Thirty-four patients with HCC PVTT treated from 2007 to 2014 with RT were identified. Biologically effective dose (BED) was calculated for each patient, and greater than the median dose delivered (75 Gray (Gy)) was evaluated as a potential prognostic factor. Survival was compared and independent prognostic variables were evaluated by a Cox proportional hazards regression model. Results: Twenty-six patients (76.5%) exhibited a radiographic response to RT, and 10 patients (29.4%) ultimately developed local failure. Local control, liver control, distant control and OS at one year were 57.1%, 36.4%, 55.2% and 57.4%, respectively. Patients who received a BED >75 Gy had a significantly better local control at 1 year (93.3% vs 45.6%; Log Rank p = 0.0184). Patients who received a BED >75 Gy also had significantly better median survival (24.7mo vs 6.1mo) and 1-year overall survival (76.5% vs 30.0%) when compared with BED <=75 Gy (Log-Rank p = 0.002). Conclusion: Our data suggest that RT should be considered for well-selected patients with HCC and PVTT for the purpose of improving local control and potentially prolonging the time to worsening venous obstruction and liver failure. When feasible, dose-escalation should be considered with a target BED of >75 Gy if normal organ dose constraints can be safely met. PMID- 29594207 TI - Patterns of loco regional failure in women with breast cancer treated by Postmastectomy Conformal Electron Beam Radiation Therapy (PMERT): Large scale single center experience. AB - Purpose: To evaluate loco regional control and describe the patterns of loco regional failure in women with breast cancer irradiated by a previously described post-mastectomy highly conformal electron beam radiotherapy technique. Materials and methods: We included all women irradiated by PMERT for non-metastatic breast cancer (BC) between 2007 and 2011 in our department. All cases of bilateral BC were excluded. All patients who experienced loco regional recurrence have been studied. Mapping patterns of regional recurrences was also performed and compared with the ESTRO and RTOG Guidelines of volume definition and delineation guidelines. Results: Among the 796 women included, 10.1% were triple-negative (TN) and 18.8% were HER2-positive and 24.6% of them had received neoadjuvant chemotherapy (CT). Internal mammary chain (IMC), supraclavicular (Level IV), infraclavicular (Levels III and II) and axillary LN (Level I) were treated in 85.6%, 88.3%, 77.9% and 14.9% of cases, respectively. With a median follow-up of 64 months (range: 6-102), 5-year locoregional (RFS and OS were 90% (95% CI: 88.1 92.4) and 90.9% (95% CI: 88.9-93), respectively. Twenty-three patients (2.9%) presented locoregional recurrences. Most of them presented aggressive biological features with grade III tumors in 17 patients (74%) with high mitotic index in 16 cases (70%) and triple negative tumors in 12 (52%). Lymphovascular invasion (LVI) was observed in 11 cases (48%). In 14 cases the locoregional recurrences were diagnosed at the same time as the metastatic disease whereas 4 patients presented distant metastases secondarily. Local (Chest wall) recurrences occurred in 13 cases (56%) with the coverage by the isodose of 47.5 Gy (isodose 95%). Fifteen regional recurrences (lymph nodes) were observed in 13 patients. Only 3 regional recurrences occurred within irradiated volumes and 12 regional recurrences occurred outside irradiated areas. Conclusion: In presented series, the local recurrences were related mostly to the tumor biological aggressivity and radio resistance. Small number was caused by geographical miss. Further follow-up and careful registration of the recurrences is needed to improve their understanding. PMID- 29594208 TI - Anemia, leukocytosis and thrombocytosis as prognostic factors in patients with cervical cancer treated with radical chemoradiotherapy: A retrospective cohort study. AB - Introduction: Anemia has long been associated with poor prognosis in patients with cervical cancer. Recently, additional hematologic parameters have emerged as potential indicators of worse outcome in this patient group. In a cohort of cervical cancer patients treated with chemoradiotherapy (CRT) and brachytherapy, we report on the prognostic significance of hematologic parameters including anemia, leukocytosis, neutrophil to lymphocyte ratio (NLR), and thrombocytosis, the effect of combining anemia with other hematologic parameters, and the effect of changes in hemoglobin levels during treatment. Materials and methods: Two hundred fifty-seven cervical cancer patients were retrospectively identified from a single cancer institution's database. Hematologic parameters were categorized as: anemia (hemoglobin <=115 g/L), leukocytosis (white blood cell count >10 * 109/L), thrombocytosis (platelets >400 * 109/L), and NLR (ratio >5). The association between clinical factors and hematologic parameters on progression free survival (PFS) and overall survival (OS) were assessed at 5 years. Results: At 5 years, both pre-treatment anemia (PFS: 60% vs 34%, p < 0.0001; OS: 68% vs 41%, p < 0.0001) and on-treatment anemia (PFS: 62% vs 40%, p < 0.0001; OS: 70% vs 48%, p < 0.0001) were significantly associated with worse survival. This adverse effect on 5-year PFS and OS was increased in patients with both pre-treatment anemia and leukocytosis (PFS: 72% vs 42%, p < 0.0001; OS: 68% vs 37%, p < 0.0001) and pre-treatment anemia and elevated NLR (PFS: 61% vs 30%, p < 0.0001; OS: 68% vs 37%, p < 0.0001). Five-year PFS (50% vs 31%) and OS (60% vs 36%) was better in patients whose pre-treatment anemia improved to normal hemoglobin levels on treatment vs those patients who were anemic both pre- and on-treatment. Conclusion: Pre-treatment and on-treatment anemia were significant, independent predictors of worse PFS and OS. Anemia and other hematologic parameters remain prognostic markers for cervical cancer patients. Improvement in PFS and OS was seen in patients with normalization of hemoglobin. PMID- 29594209 TI - Assessment of pulmonary 18F-FDG-PET uptake and cytokine profiles in non-small cell lung cancer patients treated with radiotherapy and erlotinib. AB - Purpose: To investigate effects of radiotherapy (RT) and erlotinib on pulmonary glucose uptake using 2-deoxy-2-(18F)fluoro-D-glucose (18F-FDG) positron emission tomography (PET) during and after treatment of non-small cell lung cancer (NSCLC) and to identify associations between serum cytokine levels and lung glucose uptake. Material and methods: Twenty-seven patients with advanced NSCLC, receiving RT alone or concomitant RT and erlotinib therapy, were examined by 18F FDG PET before, during, and after treatment. A total of 57 18F-FDG PET scans were analyzed. Pulmonary 18F-FDG uptake and radiotherapy dose mapping were used to acquire dose-response curves for each patient, where subsequent linear regression gave a glucose uptake level in the un-irradiated parts of the lungs (SUV0) and a response slope (DeltaSUV). Serum cytokine levels at corresponding time points were assessed using a multiplex bioassay. Correlations between the most robust cytokines and lung 18F-FDG dose response parameters were further investigated. Results: From the dose response analysis, SUV0 at post-therapy was significantly higher (P < 0.001) than at mid- and pre-therapy (45% and 58%, respectively) for the group receiving RT + erlotinib. Also, SUV0 at post-therapy was higher for patients receiving RT + erlotinib compared to RT alone (42%; P < 0.001). No differences in DeltaSUV were seen with treatments or time. SUV0 was positively associated (r = 0.47, P = 0.01) with serum levels of the chemokine C-C motif ligand 21 (CCL21) for patients receiving RT + erlotinib. Conclusions: Concomitant RT and erlotinib causes an elevation in pulmonary 18F-FDG uptake post treatment compared to RT alone. Pulmonary glucose uptake is associated with an upregulation of a chemokine (CCL21) involved in inflammatory reactions.

AB - Introduction: Nigeria has the biggest gap between radiotherapy availability and need, with one machine per 19.4 million people, compared to one machine per 250,000 people in high-income countries. This study aims to identify its patient level barriers to radiotherapy access. Material and methods: This was a cross sectional study consisting of patient questionnaires (n = 50) conducted in January 2016 to assess patient demographics, types of cancers seen, barriers to receiving radiotherapy, health beliefs and practices, and factors leading to treatment delay. Results: Eighty percent of patients could not afford radiotherapy without financial assistance and only 6% of the patients had federal insurance, which did not cover radiotherapy services. Of the patients who had completed radiotherapy treatment, 91.3% had experienced treatment delay or often cancellation due to healthcare worker strike, power failure, machine breakdown, or prolonged wait time. The timeliness of a patient's radiotherapy care correlated with their employment status and distance from radiotherapy center (p < 0.05). Conclusions: Barriers to care at a radiotherapy center in a low- and middle-income country (LMIC) have previously not been well characterized. These findings can be used to inform efforts to expand the availability of radiotherapy and improve current treatment capacity in Nigeria and in other LMICs. PMID- 29594211 TI - P4HA1: A single-gene surrogate of hypoxia signatures in oral squamous cell carcinoma patients. AB - Background and purpose: Hypoxia gene expression signatures are of high prognostic value for head and neck cancer patients. Recently, the prognostic information of a multiple-gene hypoxia signature was found to be provided by the mRNA level of P4HA1 alone (Tawk et al., 2016). Therefore, we studied the prognostic value of P4HA1 in an independent cohort of oral squamous cell carcinoma (OSCC) patients. Material and methods: Frozen tumor samples of 118 adult OSCC patients were analysed for P4HA1 mRNA level by quantitative real-time TaqManTM PCR analysis. Kaplan-Meier analysis and Cox's regression analysis were performed to characterize the prognostic impact of P4HA1 mRNA level in OSCC patients. Results: The analyzed patient cohort was divided into four subgroups according to the quartiles of the P4HA1 mRNA levels. The highest intratumoral P4HA1 mRNA level was significantly correlated with a poor overall survival (RR = 2.2; P = 0.04) and an increased risk of locoregional recurrence (RR = 4.8; P = 0.02). In patients who received radiotherapy (n = 82) highest intratumoral P4HA1 mRNA level was significantly correlated with a poor overall survival (RR = 3.4; P = 0.01) and an increased risk of locoregional recurrence (RR = 10.3; P = 0.005). Moreover, significant correlations between the P4HA1 mRNA level and the mRNA level of several EMT and stem cell markers were found. Conclusions: A high P4HA1 mRNA level, as a single-gene surrogate of hypoxia, is an independent prognostic marker for the overall survival and locoregional recurrence of OSCC patients. PMID- 29594212 TI - Cell-line dependent effects of hypoxia prior to irradiation in squamous cell carcinoma lines. AB - Purpose: To assess the impact of hypoxia exposure on cellular radiation sensitivity and survival of tumor cells with diverse intrinsic radiation sensitivity under normoxic conditions. Materials and methods: Three squamous cell carcinoma (SCC) cell lines, with pronounced differences in radiation sensitivity, were exposed to hypoxia prior, during or post irradiation. Cells were seeded in parallel for colony formation assay (CFA) and stained for gammaH2AX foci or processed for western blot analysis. Results: Hypoxia during irradiation led to increased cellular survival and reduced amount of residual gammaH2AX foci in all the cell lines with similar oxygen enhancement ratios (OER SKX: 2.31, FaDu: 2.44, UT-SCC5: 2.32), while post-irradiation hypoxia did not alter CFA nor residual gammaH2AX foci. Interestingly, prolonged exposure to hypoxia prior to irradiation resulted in differential outcome, assessed as Hypoxia modifying factor (HMF) namely radiosensitization (SKX HMF: 0.76), radioresistance (FaDu HMF: 1.54) and no effect (UT SCC-5 HMF: 1.1). Notably, radiosensitization was observed in the ATM-deficient SKX cell line while UT SCC-5 and to a lesser extent also FaDu cells showed radiation- and hypoxia-induced upregulation of ATM phosphorylation. Across all the cell lines Rad51 was downregulated whereas phosphor-DNA-PKcs was enhanced under hypoxia for FaDu and UTSCC-5 and was delayed in the SKX cell line. Conclusion: We herein report a key role of ATM in the cellular fitness of cells exposed to prolonged moderate hypoxia prior to irradiation. While DNA damage response post-irradiation seem to be mainly driven by non-homologous end joining repair pathway in these conditions, our data suggest an important role for ATM kinase in hypoxia-driven modification of radiation response. PMID- 29594213 TI - Survival and failure types after radiation therapy of vulvar cancer. AB - Background and purpose: Describe the survival rates and distribution of events on competing failure types in vulvar carcinoma after treatment with chemoradiation (CRT) or radiation (RT) alone. Material and methods: We included patients with vulvar carcinoma treated with CRT or RT between 2009 and 2014. Survival was estimated using the Kaplan-Meier method. We performed a competing risk analysis and included five competing events: loco-regional failure (LRF), distant metastasis, LRF plus distant metastasis, and death without evidence of disease, with the remaining patients denoted alive without evidence of disease. Results: 87 patients were treated. Progression free survival (PFS) and overall survival (OS) at 3 years were 40% and 57%, respectively. 41.3% of patients relapsed, most often loco-regionally. We saw significantly worse PFS and OS for patients older than 68 (p = 0.011/p = 0.010) and for patients treated with definitive RT (p = 0.004/p = 0.005). Competing risk analysis showed increased risk of LRF, and that death was most often related to vulvar cancer. Death without disease recurrence was less frequent, even in the elderly. Conclusions: LRF was the most common event. PFS and OS were inferior for elderly patients and patients treated definitively. A better understanding of these differences may be used to define risk adapted treatment strategies. PMID- 29594215 TI - Age-not Charlson Co-morbidity Index-predicts for mortality after stereotactic ablative radiotherapy for medically inoperable stage I non-small cell lung cancer. AB - Purpose: In this single institution retrospective study of patients with stage I medically inoperable non-small cell lung cancer (NSCLC) treated with stereotactic ablative radiotherapy (SABR) we attempt to model overall survival (OS) using initial prognostic variables with specific attention on the Charlson co-morbidity index (CCI). Methods: Between 2008 and 2013, 335 patients with medically inoperable stage I NSCLC were treated with SABR or hypofractionated radiotherapy (50-60 Gy in at least 5 Gy or 4 Gy fractions respectively) at our institution. Medical comorbidities and Charlson scores were determined by individual chart review. Patients were stratified into 3 groups based on the CCI score (0-1, 2-3, 4-9) and again based on the age-adjusted Charlson Comorbidity score (aCCI). Cumulative survival for each stratum was determined using the Kaplan-Meier method. Non-significant and confounding variables were identified and discounted from survival modeling. 3 sex stratified Cox regression models were tested: (1) aCCI with age and comorbidity combined; (2) age and CCI; (3) age alone, comorbidity removed. Results: The median survival was 4.4 years and the median follow up 4.7 years. The median CCI and aCCI scores were 2 and 5 respectively. Patients with aCCI 7-12 had an increased hazard of death on univariate analysis HR 2.45 (1.15-5.22 95%CI, p = 0.02) and -excluding age as a competing variable- on multivariate analysis HR 2.25 (1.04-4.84 95%CI, p = 0.04). Patients with CCI 4 9 had an increased hazard of death on univariate analysis HR 1.57(1.30-2.90) but not on multivariate analysis. On formalized testing - with either continuous or categorical variables- all three survival models yielded similar coefficients of effect. Conclusion: We identify male gender, weight loss greater than 10% and age as independent prognostic factors for patients treated with medically inoperable NSCLC treated with SABR or hypofractionated radiotherapy. Based on our survival models, age alone can be used interchangeably with aCCI or CCI plus age with the same prognostic value. Age is more reliably recorded, less prone to error and therefore a more useful metric than Charlson score in this group of patients. PMID- 29594214 TI - SDF-1/CXCR4 expression in head and neck cancer and outcome after postoperative radiochemotherapy. AB - Introduction: Outcome after postoperative radiochemotherapy (RT-CT) for patients with advanced head and neck squamous cell carcinomas (HNSCC) remains unsatisfactory, especially among those with HPV negative tumours. Therefore, new biomarkers are needed to further define subgroups for individualised therapeutic approaches. Preclinical and first clinical observations showed that the chemokine receptor CXCR4 and its ligand SDF-1 (CXCL12) play an important role in tumour cell proliferation, survival, cancer progression, metastasis and treatment resistance. However, the data on the prognostic value of SDF-1/CXCR4 expression for HNSCC are conflicting. The aim of our hypothesis-generating study was to retrospectively explore the prognostic potential of SDF-1/CXCR4 in a well-defined cohort of HNSCC patients collected within the multicenter biomarker study of the German Cancer Consortium Radiation Oncology Group (DKTK-ROG). Material and methods: Patients with stage III and IVA HNSCC of the oral cavity, oropharynx and hypopharynx were treated with resection and adjuvant radiotherapy (RT) with >=60 Gy and concurrent cisplatin-based chemotherapy (CT). Tissue micro-arrays (TMAs) from a total of 221 patients were generated from surgical specimens, 201 evaluated for the SDF-1 and CXCR4 expression by immunofluorescence and correlated with clinico-pathological and outcome data. Results: In univariate and multivariate analyses intracellular SDF-1 expression was associated with lower loco-regional control (LRC) in the entire patient group as well as in the HPV16 DNA negative subgroup. CXCR4 expression showed a trend for lower LRC in the univariate analysis which was not confirmed in the multivariate analysis. Neither for SDF-1 nor CXCR4 expression associations with distant metastasis free or overall survival were found. Conclusions: Our exploratory data support the hypothesis that overexpression of intracellular SDF-1 is an independent negative prognostic biomarker for LRC after postoperative RT-CT in high-risk HNSCC. Prospective validation is warranted and further exploration of SDF-1/CXCR4 as a potential therapeutic target to overcome treatment resistance in HNSCC appears promising. PMID- 29594216 TI - A predictive model for residual disease after (chemo) radiotherapy in oropharyngeal carcinoma: Combined radiological and clinical evaluation of tumor response. AB - Background and purpose: Early detection of Residual disease (RD) is vital for salvage possibilities after (chemo) radiatiotherapy for oropharyngeal carcinoma (OPC). We standardized clinical investigation to test its added value to MRI response evaluation and investigated the benefit of FDG-PET/CT. Materials and methods: Radiological response evaluation using Ojiri-score was done for 234 patients with OPC, using MRI 12 weeks after (chemo) radiotherapy between 2010 and 2014. The presence of mucosal lesions and/or major complaints (still completely tube feeding-dependent and/or opiate-dependent because of swallowing problems) was scored as clinical suspicion (CS). Retrospectively, the performance of Ojiri to predict RD was compared to CS and both combined using Pearson Chi-squared. Of the whole group, FDG-PET/CT metabolic response (MR) was available in 50 patients. Results: Twelve out of 234 patients (5.1%) had RD. Ojiri and CS had excellent negative predictive value (NPV) (98% and 100% respectively). The combination of CS and Ojiri reduced false positives by 32% (38-26 patients) without lowering NPV (98%). No patients with complete MR (n = 39) at the FDG-PET/CT had RD compared to 5 (45%) with partial MR. Conclusion: For response evaluation in OPC, the combination of CS and Ojiri-score improved the predictive accuracy by reducing false positives compared to them individually. FDG-PET/CT is promising to further reduce false positives. PMID- 29594217 TI - Treatment constraints for single dose external beam preoperative partial breast irradiation in early-stage breast cancer. AB - Background: Following breast-conserving surgery and post-operative 3D-conformal accelerated partial breast irradiation (APBI), suboptimal cosmetic results have been reported. Preoperative radiation delivery to the intact tumor enables better target visualization and treatment volume reduction. Single dose preoperative APBI has the potential to improve toxicity profiles, reduce treatment burden and enable in vivo exploration of breast cancer radiogenomics. Purpose: Develop practical guidelines for single dose external beam preoperative APBI. Methods: Recommended dose constraints were derived from pooled dosimetry estimates from 2 clinical trials. In an American dose escalation trial, a uniform 15, 18 or 21 Gy dose has previously been evaluated for non-lobular cT1N0 or low/intermediate grade DCIS <2 cm in prone position (n = 32). In the Netherlands, the feasibility of ablative APBI (20 Gy to GTV, 15 Gy to CTV) to non-lobular cT1N0 in supine position, is currently being explored (n = 15). The dosimetric adherence to the developed constraints was evaluated in new APBI plans with a 21 Gy uniform dose but an extended CTV margin (n = 32). Results: Dosimetric data pooling enabled the development of practical guidelines for single dose preoperative APBI. Conclusion: The developed guidelines will allow further explorations in the promising field of single dose preoperative external beam APBI for breast cancer treatment. PMID- 29594218 TI - The predictive value of nadir neutrophil count during treatment of cervical cancer: Interactions with tumor hypoxia and interstitial fluid pressure (IFP). AB - Background and purpose: Hypoxia, high interstitial fluid pressure (IFP) and immune effects have individually been shown to modulate radiotherapy (RT) response in cervical cancer. The aim of this study was to investigate the interplay between hypoxia or IFP and circulating neutrophil levels, and their combined effect on survival following RT. Material and methods: A total of 287 FIGO stage IB to IIIB cervical cancer patients treated with RT or RT and cisplatin (RTCT) were included. Tumor hypoxia and IFP were measured at baseline prior to treatment. Absolute neutrophil count (ANC) was measured at baseline and weekly during treatment. Median follow up was 7.1 years. Results: High nadir ANC at the point of maximal myelosuppression was a stronger predictor of inferior survival than high baseline ANC after adjusting for clinical prognostic factors and treatment (RT vs. RTCT). The predictive effect of nadir ANC was most evident in patients with well-oxygenated tumors or tumors with high IFP at diagnosis. Conclusions: This study provides new information about the combined influence of the tumor microenvironment and myeloid cells on the survival of cervical cancer patients treated with RT/RTCT to motivate the development of new treatments based on molecular targeting of immune-based radioresistance pathways. PMID- 29594219 TI - Feasibility of stereotactic body radiotherapy for locally-advanced non-small cell lung cancer. AB - SBRT was feasible for approximately half of the locally-advanced NSCLC patients we assessed and for these patients has the potential to reduce a 30 fraction course to 12 fractions. Using SBRT in this setting requires compromises in techniques and further compromises may allow SBRT in a greater proportion of patients. PMID- 29594220 TI - Role of radiotherapy in extracranial metastatic malignant melanoma in the modern era. AB - Background: To assess the role of radiotherapy in metastatic malignant melanoma (MM) patients in modern era. Materials and methods: This is a retrospective study of MM patients treated with radiotherapy at Mayo Clinic from 1999 to 2014. Patients with pre- and post-treatment imaging studies (CT, MRI, and/or PET/CT) were assessed for metastasis failure (MF), regional/distant failure, and overall survival (OS). Results: In 75 MM patients, 56 and 68 lesions were treated with conventional/hypofractionated radiotherapy (CHRT) and stereotactic body radiotherapy (SBRT), respectively. The median doses for CHRT and SBRT were 30 Gy and 50 Gy, respectively. 1-year MF was 17% (SBRT 6% vs CHRT 31%, p < 0.01). 1 year regional (5% vs 29%, p < 0.01) and distant progression (75% vs 89%, p < 0.01) were improved with SBRT. Median OS was 15.6 months (CHRT 7.0 vs SBRT 22.9, p < 0.01). Prognostic factors for OS included age <=55 years (RR 0.25), oligometastatic disease (RR 0.34), SBRT (RR 0.38) and treating all lesions (RR 0.28, all p < 0.01). Conclusions: SBRT for extracranial MM exhibited improved MF compared with CHRT, consistent with intracranial radiosurgery data. Though these data are retrospective and subject to selection bias, our findings support the prudent use of SBRT in a select group of favorable, oligometastatic MM patients, and should be discussed as an alternative to surgery and ablation. PMID- 29594221 TI - Correlation between urinary dose and delayed radiation cystitis after 78 Gy intensity-modulated radiotherapy for high-risk prostate cancer: A 10-year follow up study of genitourinary toxicity in clinical practice. AB - Purpose: To investigate the factors associated with the risk of long-term genitourinary (GU) toxicity among high-risk prostate cancer (PC) patients treated with high-dose intensity-modulated radiotherapy (IMRT). Methods and materials: Between 2000 and 2011, PC patients treated with 78 Gy in 39 fractions delivered by IMRT combined with neo-adjuvant hormonal therapy were selected from among our database. GU toxicities and clinical factors, as well as separate anatomical urinary structures, were evaluated in terms of their associations. Results: A total of 309 patients was included in this study. The median follow-up was 104 months (range: 24-143 months). The most frequently observed late grade >=2 GU toxicity was hematuria (11.2%: 10-year actuarial risk) with radiation cystitis observed in the majority of patients. In univariate analysis, late grade >=2 hematuria was associated with the exposure to doses >75 Gy (V75) of the bladder neck and V70 of the bladder wall, as well as with T stage. V75 of the bladder neck remained significant in multivariate analysis (p = 0.049). Conclusions: At the 10-year follow up of high-dose IMRT, a major concern was proved to be delayed cystitis related to the higher volume of bladder neck dose exposed excess over 75 Gy. PMID- 29594223 TI - Late cutaneous effects of a local potent steroid during adjuvant radiotherapy for breast cancer. AB - Purpose: The aim of this study was to evaluate whether treatment with a local potent corticosteroid during adjuvant external radiotherapy (ERT) of breast cancer is associated with late skin toxicity. Material and methods: Sixty patients (32 treated with potent corticoid cream versus 28 controls treated with moisturizer) who had been included in a randomized study on prophylactic local corticosteroid treatment under adjuvant ERT in 2009 and 2010 were subjected to a follow-up study in 2016.Assessments of skin texture were registered according to the Late Radiation Morbidity Scoring Scheme (RTOG). Dryness, skin colour and skin thickness were objectively measured using non-invasive instruments. The patients were assessed for differences between their treated and untreated breasts. Results: Skin atrophy was not noticed in any of the 60 patients. Objective instrumental measurements did not reveal any significant differences in skin dryness, colour, pigmentation or skin thickness over the average follow-up time of six years. Clinical assessment based on the RTOG scoring system revealed that the odds ratio of having late skin problems in patients treated with moisturizer compared to patients treated with corticosteroid was 3.2 (95% CI: 1.0 10.1).Patients reported minor cosmetic dermatological sequelae. Seven patients developed telangiectasia, which caused cosmetic inconvenience. Conclusion: In this study, prophylactic corticosteroid treatment to ameliorate radiation dermatitis during adjuvant ERT of breast cancer was not associated with an increase in late skin toxicity nor did it result in skin atrophy. This study is limited by its small sample size, and the risk for false positive findings. PMID- 29594222 TI - The impact of the IGF-1 system of cancer cells on radiation response - An in vitro study. AB - Background: Overexpression of the insulin-like growth factor-1 receptor (IGF-1R) is associated with increased cell proliferation, differentiation, transformation, and tumorigenicity. Additionally, signaling involved in the resistance of cancer cells to radiotherapy originates from IGF-1R. The purpose of this study was to investigate the role of the IGF-1 system in the radiation response and further evaluate its effect on the expression of DNA repair pathway genes. Methods: To inhibit the IGF-1 system, we stably transfected the Caco-2 cell line to express a kinase-deficient IGF-1R mutant. We then studied the effects of this mutation on cell growth, the response to radiation, and clonogenic survival, as well as using a cell viability assay to examine DNA damage and repair. Finally, we performed immunofluorescence for gamma-H2AX to examine double-strand DNA breaks and evaluated the expression of 84 key genes involved in DNA repair with a real-time PCR array. Results: Mutant IGF-1R cells exhibited significantly blunted cell growth and viability, compared to wild-type cells, as well as reduced clonogenic survival after gamma-irradiation. However, mutant IGF-1R cells did not show any significant delays in the repair of radiation-induced DNA double-strand breaks. Furthermore, expression of mutant IGF-1R significantly down-regulated the mRNA levels of BRCA2, a major protein involved in homologous recombination DNA repair. Conclusion: These results indicate that blocking the IGF-1R-mediated signaling cascade, through the expression of a kinase-deficient IGF-1R mutant, reduces cell growth and sensitizes cancer cells to ionizing radiation. Therefore, the IGF-1R system could be a potential target to enhance radio-sensitivity and the efficacy of cancer treatments. PMID- 29594224 TI - Prospective analysis of in vivo landmark point-based MRI geometric distortion in head and neck cancer patients scanned in immobilized radiation treatment position: Results of a prospective quality assurance protocol. AB - Purpose: Uncertainties related to geometric distortion are a major obstacle for effectively utilizing MRI in radiation oncology. We aim to quantify the geometric distortion in patient images by comparing their in-treatment position MRIs with the corresponding planning CTs, using CT as the non-distorted gold standard. Methods: Twenty-one head and neck cancer patients were imaged with MRI as part of a prospective Institutional Review Board approved study. MR images were acquired with a T2 SE sequence (0.5 * 0.5 * 2.5 mm voxel size) in the same immobilization position as in the CTs. MRI to CT rigid registration was then done and geometric distortion comparison was assessed by measuring the corresponding anatomical landmarks on both the MRI and the CT images. Several landmark measurements were obtained including; skin to skin (STS), bone to bone, and soft tissue to soft tissue at specific levels in horizontal and vertical planes of both scans. Inter observer variability was assessed and interclass correlation (ICC) was calculated. Results: A total of 430 landmark measurements were obtained. The median distortion for all landmarks in all scans was 1.06 mm (IQR 0.6-1.98). For each patient 48% of the measurements were done in the right-left direction and 52% were done in the anteroposterior direction. The measured geometric distortion was not statistically different in the right-left direction compared to the anteroposterior direction (1.5 +/- 1.6 vs. 1.6 +/- 1.7 mm, respectively, p = 0.4). The magnitude of distortion was higher in the STS peripheral landmarks compared to the more central landmarks (2.0 +/- 1.9 vs. 1.2 +/- 1.3 mm, p < 0.0001). The mean distortion measured by observer one was not significantly different compared to observer 2, 3, and 4 (1.05, 1.23, 1.06 and 1.05 mm, respectively, p = 0.4) with ICC = 0.84. Conclusion: MRI geometric distortions were quantified in radiotherapy planning applications with a clinically insignificant error of less than 2 mm compared to the gold standard CT. PMID- 29594225 TI - Retrospective methods to estimate radiation dose at the site of breast cancer development after Hodgkin lymphoma radiotherapy. AB - Background: An increased risk of breast cancer following radiotherapy for Hodgkin lymphoma (HL) has now been robustly established. In order to estimate the dose response relationship more accurately, and to aid clinical decision making, a retrospective estimation of the radiation dose delivered to the site of the subsequent breast cancer is required. Methods: For 174 Dutch and 170 UK female patients with breast cancer following HL treatment, the 3-dimensional position of the breast cancer in the affected breast was determined and transferred onto a CT based anthropomorphic phantom. Using a radiotherapy treatment planning system the dose distribution on the CT-based phantom was calculated for the 46 different radiation treatment field set-ups used in the study population. The estimated dose at the centre of the breast cancer, and a margin to reflect dose uncertainty were determined on the basis of the location of the tumour and the isodose lines from the treatment planning. We assessed inter-observer variation and for 47 patients we compared the results with a previously applied dosimetry method. Results: The estimated median point dose at the centre of the breast cancer location was 29.75 Gy (IQR 5.8-37.2), or about 75% of the prescribed radiotherapy dose. The median dose uncertainty range was 5.97 Gy. We observed an excellent inter-observer variation (ICC 0.89 (95% CI: 0.74-0.95)). The absolute agreement intra-class correlation coefficient (ICC) for inter-method variation was 0.59 (95% CI: 0.37-0.75), indicating (nearly) good agreement. There were no systematic differences in the dose estimates between observers or methods. Conclusion: Estimates of the dose at the point of a subsequent breast cancer show good correlation between methods, but the retrospective nature of the estimates means that there is always some uncertainty to be accounted for. PMID- 29594226 TI - Prognostic impact of leukocyte counts before and during radiotherapy for oropharyngeal cancer. AB - Introduction: Peripheral blood count components are accessible and evidently predictive in other cancers but have not been explored in oropharyngeal carcinoma. We examine if there is an association between the use of intensity modulated radiotherapy (IMRT) or intensity-modulated proton therapy (IMPT) and lymphopenia, as well as if there is an association between baseline neutrophilia, baseline leukocytosis and lymphocyte nadir in oropharyngeal cancer. Materials and Methods: Analysis started with 150 patients from a previous case to case study design, which retrospectively identified adults with oropharyngeal carcinoma, 100 treated with IMRT in 2010-2012 and 50 treated with IMPT in 2011-2014. Pretreatment leukocyte, neutrophil, lymphocyte, and hemoglobin levels were extracted, as were neutrophil and lymphocyte nadir levels during radiotherapy. We retained 137 patients with recorded pre-treatment leukocyte and neutrophil levels for associated analysis and 114 patients with recorded lymphocyte levels during radiation and associated analysis. Multivariate survival analyses were done with Cox regression. Results: The radiotherapy type (IMRT vs. IMPT) was not associated with lymphopenia (grade 3 P > .99; grade 4 P = .55). In univariate analyses, poor overall survival was associated with pretreatment neutrophilia (hazard ratio [HR] 5.58, 95% confidence interval [CI] 1.99-15.7, P = .001), pretreatment leukocytosis (HR 4.85, 95% CI 1.73-13.6, P = .003), grade 4 lymphopenia during radiotherapy (HR 3.28, 95% CI 1.14-9.44, P = .03), and possibly smoking status >10 pack-years (HR 2.88, 95% CI 1.01-8.18, P = .05), but only T status was possibly significant in multivariate analysis (HR 2.64, 95% CI 0.99-7.00, P = .05). Poor progression-free survival was associated with pretreatment leukocytosis and T status in univariate analysis, and pretreatment neutrophilia and advanced age on multivariate analysis. Conclusions: Treatment modality did not affect blood counts during radiotherapy. Pretreatment neutrophilia, pretreatment leukocytosis, and grade 4 lymphopenia during radiotherapy were associated with worse outcomes after, but establishing causality will require additional work with increased statistical power. PMID- 29594227 TI - Sites of recurrent disease and prognostic factors in SCLC patients treated with radiochemotherapy. AB - Objectives: Concurrent radiochemotherapy (RCHT) is standard treatment in locally advanced small cell lung cancer (SCLC) patients. Due to conflicting results on elective nodal irradiation (ENI) or selective node irradiation (SNI) there is no clear evidence on optimal target volumes. Therefore, the purposes of this study were to assess the sites of recurrent disease in SCLC and to evaluate the feasibility of SNI versus ENI. Methods: A retrospective single-institution study of 43 consecutive patients treated with RCHT was performed. After state-of-the art staging including FDG-PET/CT, all patients underwent three-dimensional conformal radiotherapy to a total dose of 45 Gy in twice-daily fractions of 1.5 Gy starting concurrently with the first or second chemotherapy cycle. All sites of loco-regional recurrences were correlated to the initial tumor and dose delivered. The impact of potential prognostic variables on outcome was evaluated using the Cox-regression model. Results: 13 patients (30%) relapsed locally or regionally: six within the initial primary tumor volume, five within the initially affected lymph nodes, one metachronously within primary tumor and initially affected lymph nodes, and one both inside and outside of the initial nodal disease. All sites of loco-regional recurrence had received 92-106% of the prescribed dose. Conclusion: In our study most recurrences occurred within the primary tumor or initially affected lymph nodes, or distantly. We did not register any case of isolated nodal failure, supporting the use of selective nodal irradiation, possibly with the addition of supraclavicular irradiation in patients with nodal disease in the upper mediastinum. PMID- 29594228 TI - VMAT radiation-induced nausea and vomiting in adjuvant breast cancer radiotherapy: The incidental effect of low-dose bath exposure. AB - Background and purpose: To investigate the hypothesis on low-dose bath exposure related to radiation-induced nausea and vomiting (RINV) in adjuvant breast volumetric modulated arch therapy (VMAT). Methods and materials: A total of 106 consecutive breast cancer patients (pts) treated with adjuvant radiotherapy (RT) with VMAT from January 2013 to May 2016 were evaluated retrospectively. For each pt, a planning CT was reimported and the coeliac plexus and gastroesophageal junction with gastric mouth (GEJCPs) were contoured as a new organ at risk (OAR) in the upper abdominal area. RINV was associated with Dmax and Dmean to GEJCPs. Univariate analysis with chi2, t-test, and Pearson's covariance was used for statistical analysis. Results: Of 106 pts, 64% complained of acute RINV according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. RINV was related to Dmax > 10 Gy and Dmean > 3 Gy to GEJCPs (P < 0.005). The radiation breast side and planning target volume (PTV) correlated with RINV. Conclusions: RINV in VMAT breast radiotherapy could be a new emerging acute side effect due to a low dose bath to upper abdominal structures such as the GEJCPs. A Dmax < 10 Gy and Dmean < 3 Gy to GEJCPs should be constrained in VMAT planning to minimize RINV risk in breast radiotherapy.

Traditionally the HPV status is tested through invasive lab test. Recently, the rapid development of statistical image analysis techniques has enabled precise quantitative analysis of medical images. The quantitative analysis of Computed Tomography (CT) provides a non-invasive way to assess HPV status for oropharynx cancer patients. We designed a statistical radiomics approach analyzing CT images to predict HPV status. Various radiomics features were extracted from CT scans, and analyzed using statistical feature selection and prediction methods. Our approach ranked the highest in the 2016 Medical Image Computing and Computer Assisted Intervention (MICCAI) grand challenge: Oropharynx Cancer (OPC) Radiomics Challenge, Human Papilloma Virus (HPV) Status Prediction. Further analysis on the most relevant radiomic features distinguishing HPV positive and negative subjects suggested that HPV positive patients usually have smaller and simpler tumors. PMID- 29594230 TI - Local control and overall survival after frameless radiosurgery: A single center experience. AB - Introduction: Stereotactic radiosurgery (SRS) has been increasingly advocated for 1-3 small brain metastases. The goal of this study was to evaluate the clinical results in patients with brain metastases treated with LINAC-based SRS using a thermoplastic mask (non-invasive fixation system) and Image-Guided Radiotherapy (IGRT). Material and Methods: In this single-institution study 48 patients with 77 brain metastases were treated between February 2012 and January 2014. The prescribed dose was 20 Gy or 18 Gy as a single fraction. SRS was performed with a True Beam STX Novalis Radiosurgery LINAC (Varian Medical Systems). The verification of positioning was done using the BrainLAB ExacTrac (r) X-ray 6D system and cone-beam CT. Results: In 69 of 77 treated brain metastases (90%) the follow-up was documented on MR imaging performed every 3 months. Mean follow-up time was 10.86 months. Estimated 1-year local control was 83%, using the Kaplan Meier method. In 7/69 brain metastases (10%) local failure (LF) was diagnosed. Median progression free survival (PFS) was 3.73 months, largely due to distant brain relapse. A GTV of <=2.0 cm3 was significantly associated with a better PFS than a GTV >2.0 cm3. Extracranial stable disease and GTV <=2.5 cm3 were significant predictors of OS.We observed 2 cases of radiation necrosis diagnosed by histology after surgical resection. No other cases of severe side effects (CTACE >= 3) were observed. Conclusion: LINAC-based frameless SRS with the BrainLAB Mask using the BrainLAB ExacTrac (r) X-ray 6D system for patient positioning is well tolerated, safe and leads to favorable crude local control of 90%. In our experience, local control after frameless (ringless) SRS is as good as ring-based SRS reported in literature. Without invasive head fixation, radiotherapy is more comfortable for patients. PMID- 29594231 TI - Radiotherapy dose-distribution to the perirectal fat space (PRS) is related to gastrointestinal control-related complications. AB - Traditionally rectal symptoms following pelvic/prostate radiotherapy are correlated to the dosimetry of the anorectum or a substructure of this. It has been suggested that the perirectal fat space (PRS) surrounding the rectum may also be relevant. This study considers the delineation and dosimetry of the PRS related to both rectal bleeding and control-related toxicity. Initially, a case control cohort of 100 patients from the RADAR study were chosen based on presence/absence of rectal control-related toxicity. Automated contouring was developed to delineate the PRS. 79 of the 100 auto-segmentations were considered successful. Balanced case-control cohorts were defined from these cases. Atlas of Complication Incidence (ACI) were generated to relate the DVH of the PRS with specific rectal symptoms; rectal bleeding and control-related symptoms (LENT/SOM). ACI demonstrated that control-related symptoms were related to the dose distribution to the PRS which was confirmed with Wilcoxon rank sum test (p < 0.05). To the authors knowledge this is the first study implicating the dose distribution to the PRS to the incidence of control-related symptoms of rectal toxicity. PMID- 29594232 TI - Increasing genomic instability during cancer therapy in a patient with Li Fraumeni syndrome. AB - Background: Li-Fraumeni syndrome (LFS) is a cancer predisposition disorder characterized by germline mutations of the p53 tumor-suppressor gene. In response to DNA damage, p53 stimulates protective cellular processes including cell-cycle arrest and apoptosis to prevent aberrant cell proliferation. Current cancer therapies involve agents that damage DNA, which also affect non-cancerous hematopoietic stem/progenitor cells. Here, we report on a child with LFS who developed genomic instability during craniospinal irradiation for metastatic choroid plexus carcinoma (CPC). Case presentation: This previously healthy 4-year old boy presented with parieto-temporal brain tumor, diagnosed as CPC grade-3. Screening for cancer-predisposing syndrome revealed heterozygous p53 germline mutation, leading to LFS diagnosis. After tumour resection and systemic chemotherapy, entire craniospinal axis was irradiated due to leptomeningeal seeding, resulting in disease stabilization for nearly 12 months. Blood lymphocytes of LFS patient (p53-deficient) and age-matched tumor-children (p53 proficient) were collected before, during and after craniospinal irradiation and compared with asymptomatic carriers for identical p53 mutation, not exposed to DNA-damaging treatment. In p53-deficient lymphocytes of LFS patient radiation induced DNA damage failed to induce cell-cycle arrest or apoptosis. Although DNA repair capacity was not impaired, p53-deficient blood lymphocytes of LFS patient showed significant accumulation of 53BP1-foci during and even several months after irradiation, reflecting persistent DNA damage. Electron microscopy revealed DNA abnormalities ranging from simple unrepaired lesions to chromosomal abnormalities. Metaphase spreads of p53-deficient lymphocytes explored by mFISH revealed high amounts of complex chromosomal aberrations after craniospinal irradiation. Conclusions: Tumor suppressor p53 plays a central role in maintaining genomic stability by promoting cell-cycle checkpoints and apoptosis. Here, we demonstrate that a patient with LFS receiving craniospinal irradiation including large volumes of bone marrow developed progressive genomic instability of the hematopoietic system. During DNA-damaging radiotherapy, genome-stabilizing mechanisms in proliferating stem/progenitor cells are perturbed by p53 deficiency, increasing the risk of cancer initiation and progression.

PMID- 29594234 TI - Strong radioprotective FGF1 signaling down-regulates proliferative and metastatic capabilities of the angiosarcoma cell line, ISOS-1, through the dual inhibition of EGFR and VEGFR pathways. AB - Background and purpose: Angiosarcoma is associated with a poor prognosis and is treated with radiotherapy. Although FGF1 is a potential radioprotector, the influence of FGF1 on the malignancy of angiosarcoma remains unknown. Materials and methods: Highly stable FGF1 mutants, which exhibit stronger mitogenic activity than wild-type FGF1, were examined as strong radioprotectors and signaling agonists to clarify the effects of FGF1 on the murine angiosarcoma cell line ISOS-1. Results: FGF1 mutants reduced colony formation by and the in vitro invasion and migration of ISOS-1 cells, in addition to an increase in radiosensitivity to X-rays. In contrast, an FGFR inhibitor blocked the inhibitory effects of FGF1 mutants on colony formation, invasion, and migration. siRNA targeting the Fgfr1 gene showed that strong FGFR1 signaling reduced colony formation by ISOS-1 cells. However, the FGF1 mutant reduced the activation of VEGFRs and EGFRs in ISOS-1 cells more strongly than wild-type FGF1. Moreover, the inhibition of VEGFRs and EGFRs synergistically reduced colony formation by and invasion and migration of ISOS-1 cells. Conclusion: These results suggest that strong FGF1 signaling exerts not only radioprotective effects, but also inhibitory effects on proliferative and metastatic capacities of angiosarcoma through the dual inhibition of EGFR and VEGFR pathways. PMID- 29594236 TI - Treatment de-escalation for HPV-driven oropharyngeal cancer: Where do we stand? AB - HPV-driven oropharyngeal cancers have significantly better survival rates than tobacco and alcohol induced head and neck cancers. As HPV-positive patients are younger, healthier and far more likely to survive their disease, long-term treatment side effects are becoming a major issue. This has led the scientific and medical community to reassess the current treatment protocols in order to develop less toxic strategies while maintaining good oncological outcomes. In this article, we discuss the ongoing treatment de-escalation trials and highlight the issues raised by these studies. PMID- 29594237 TI - PARADIGM-2: Two parallel phase I studies of olaparib and radiotherapy or olaparib and radiotherapy plus temozolomide in patients with newly diagnosed glioblastoma, with treatment stratified by MGMT status. AB - Glioblastoma has a dismal prognosis and molecular targeted agents have failed to improve outcomes to date. PARADIGM-2 is a phase I dose escalation study evaluating olaparib plus radiotherapy +/- temozolomide in newly diagnosed glioblastoma, using MGMT methylation status to stratify patients and inform treatment schedules. PMID- 29594238 TI - Retrospective assessment of MRI-based volumetric changes of normal tissues in glioma patients following radio(chemo)therapy. AB - In glioma patients, linac-based photon beam irradiation is a widely applied therapy, which achieves highly conformal target volume coverage, but is also known to cause side-effects to adjacent areas of healthy tissue. Apart from subjective measures, such as quality of life assessment and neurocognitive function tests, objective methods to quantify tissue damage are needed to assess this impact. Magnetic resonance imaging (MRI) is a well-established method for brain tumor diagnoses as well as assessing treatment response. In this study, we retrospectively assessed volumetric changes of gray matter (GM) and white matter (WM) in glioma patients following photon irradiation using a heterogeneous MRI dataset obtained in routine clinical practice at different sites with imaging parameters and magnetic field strengths. We found a significant reduction in WM volume at one year [Formula: see text] and two years [Formula: see text] post radio(chemo)therapy whereas corresponding GM volumes did not change significantly ([Formula: see text] and [Formula: see text], respectively). More importantly, we also found large variations in the segmented tissue volumes caused by the heterogeneous MR data, thus potentially masking more subtle tissue changes over time. On the basis of these observations, we present suggestions regarding data acquisitions in future prospective MR studies to assess such volumetric changes. PMID- 29594240 TI - Skull base or cervical vertebral osteomyelitis following chemoradiotherapy for pharyngeal carcinoma: A serious but treatable complication. AB - Osteomyelitis, infection of the bone and marrow, following high dose (chemo )radiotherapy for head and neck cancer is uncommon and rarely seen in the cervical spine or temporal bone. Due to its proximity to critical structures, osteomyelitis in the latter regions could carry potentially important consequences. Furthermore, involvement near the skull base (e.g. temporal bone and high cervical vertebrae) presents unique challenges in diagnosis (especially in the differentiation from disease recurrence) and treatment, making early detection and timely intervention critical. In this report, we describe two cases of osteomyelitis, one involving the temporal bone and the other affecting the 2nd and 3rd cervical vertebrae, diagnosed and treated with good outcome in the setting of definitive chemoradiotherapy for locally advanced pharyngeal carcinomas. We suggest that for new or evolving post-radiotherapy osseous changes in regions that have received a high dose of radiotherapy, associated with unexpected and deteriorating spinal symptoms such as pain and spasm, radiation related osteomyelitis should be considered in the differential diagnosis from tumor progression. Timely referral to a surgical oncologist and infectious diseases specialist is paramount in achieving satisfactory clinical outcomes. PMID- 29594239 TI - The posterior cerebellum, a new organ at risk? AB - Eekers et al. have recently proposed a neuro-oncology atlas, which was co authored by most centers associated in the European Proton Therapy Network (EPTN; Figure 1). With the introduction of new treatment techniques, such as integrated magnetic resonance imaging and linear accelerators (MR-linac) or particle therapy, the prediction of clinical efficacy of these more costly treatment modalities becomes more relevant. One of the side-effects of brain irradiation, being cognitive decline, is one of the toxicities most difficult to measure and predict. In order to validly compare different treatment modalities, 1) a uniform nomenclature of the organs at risk (OARs), 2) uniform atlas-based delineation [e.g., Eekers et al.], 3) long-term follow-up data with standardized cognitive tests, 4) a large patient population, and 5) (thus derived) validated normal tissue complication probability (NTCP) models are mandatory. Apart from the Gondi model, in which the role of the dose to 40% of both hippocampi (HC) proves to be significantly related to cognition in 18 patients, no similar models are available. So there is a strong need for more NTCP models, on HC, brain tissue and possible other relevant brain structures. In this review we summarize the available evidence on the role of the posterior cerebellum as a possible new organ at risk for cognition, which is deemed relevant for irradiation of brain and head and neck tumors.

AB - Well-being of cancer patients and survivors is a challenge worldwide, considering the often chronic nature of the disease. Today, a large number of initiatives, products and services are available that aim to provide strategies to face the challenge of well-being in cancer patients; nevertheless the proposed solutions are often non-sustainable, costly, unavailable to those in need, and less well received by patients. These challenges were considered in designing FORECAST, a cloud-based personalized intelligent virtual coaching platform for improving the well-being of cancer patients. Personalized coaching for cancer patients focuses on physical, mental, and emotional concerns, which FORECAST is able to identify. Cancer patients can benefit from coaching that addresses their emotional problems, helps them focus on their goals, and supports them in coping with their disease-related stressors. Personalized coaching in FORECAST offers support, encouragement, motivation, confidence, and hope and is a valuable tool for the wellbeing of a patient. PMID- 29594243 TI - Resolution of atelectasis during radiochemotherapy of lung cancer with serious implications for further treatment. A case report. AB - Local failure is a major cause for low overall survival rates in advanced non small cell lung cancer (NSCLC). Among others, radioresistant tumor clones as well as geographical miss can explain these high local failure rates. One reason for geographical miss is a change of tumor related atelectasis in the course of radiotherapy. We present the case of a patient with UICC Stage IIIb NSCLC who presented with a large tumor related atelectasis. During definitive radiochemotherapy, the atelectasis resolved, which resulted in a massive tumor shift out of the planning target volume within 2 days. Without close monitoring by cone beam CTs and prompt replanning, this would have led to a geographical miss and relevant underdosage of the tumor. Furthermore, changes in anatomy and pulmonary function during treatment had implications for organs at risk and opened windows for dose escalation. We suggest at least biweekly CBCTs in patients with poststenotic atelectasis to ensure the rapid detection of geographical changes of the target and subsequent intervention if necessary. PMID- 29594244 TI - Combining radiotherapy and ipilimumab induces clinically relevant radiation induced abscopal effects in metastatic melanoma patients: A systematic review. AB - Background: In the last years, limited studies have described that radiotherapy could produce important distant responses in unirradiated sites, the so-called "abscopal effect". Recent evidence suggests that radiotherapy induces antigen release from tumor, in this way activating the immune system. However, radiotherapy alone is rarely enough to induce the systemic response requested for control of the metastases. With the advent of immunotherapy, the immune checkpoint inhibitors (ICI) have demonstrated impressive efficacy in various metastatic cancers. Currently, preclinical and clinical studies have reported a significant increase of abscopal responses in patients treated with the combination of radiotherapy and ICI. The purpose of this review was summarizing the clinical studies combining radiotherapy and ipilimumab (ipi), particularly focusing on abscopal responses. Methods and Materials: Databases of Medline (via Pubmed) from 2009 to June 2, 2017 were reviewed to obtain English language studies reporting clinical abscopal effect in the combination of radiotherapy with exclusive ipi in metastatic melanoma cancers. Included studies reported the abscopal effect as a primary endpoint, and as secondary endpoint included overall survival and toxicity. Results: A total of 16 studies met the inclusion criteria. These studies included a total of 451 patients, and in 5/16 studies the patients were treated on research protocols and followed-up prospectively. The median reported abscopal effect and OS were 26.5% and 19 months, respectively. The median toxicity >= Grade 3 was 18.3% ranged from 10% to 20%. Conclusion: Early clinical outcomes reports suggest that the combination of ipilimumab and RT may improve survival in metastatic melanoma patients. The abscopal responses become a clinically relevant effect of such combination and should be studied in controlled randomized trials. PMID- 29594245 TI - Definitive chemoradiotherapy with low-dose continuous 5-fluorouracil reduces hematological toxicity without compromising survival in esophageal squamous cell carcinoma patients. AB - Background and purpose: To compare chemoradiotherapy (CRT) with low-dose continuous 5-fluorouracil (5FU) to CRT with 5FU+cisplatin (CDDP) for esophageal squamous cell carcinoma (ESCC) in a retrospective cohort study. Methods and materials: We reviewed the cases of Stage I-IV ESCC patients who underwent definitive CRT in 2000-2014. Concomitant chemotherapy was one of the three regimens: (1) high-dose intermittent 5FU and CDDP (standard-dose FP: SDFP), (2) low-dose continuous 5FU and CDDP (LDFP), or (3) low-dose continuous 5FU (LD5FU). The general selection criteria for chemotherapy were: SDFP for patients aged <70 yrs; LDFP for those aged 70-74 yrs; LD5FU for those aged >=75 yrs or with performance status (PS) >=3. Propensity scores were derived with chemotherapy (LD5FU vs. 5FU+CDDP) as the dependent variable. Results: In a multivariate analysis, chemotherapy (LD5FU vs. SDFP, p = .24; LDFP vs. SDFP, p = .52) did not affect the overall survival (OS). LD5FU caused significantly less grade 3-4 leukopenia (9%) compared to SDFP (47%) and LDFP (44%) (p < .001). In a propensity matched analysis, LD5FU affected neither OS (HR 1.06; 95%CI 0.55-2.05; p = .87) nor progression-free survival (HR 0.95, 95%CI 0.50-1.81; p = .87). Conclusion: CRT with low-dose continuous 5FU may be a less toxic option for elderly ESCC patients. PMID- 29594246 TI - Surgery vs. primary radiotherapy in early-stage oropharyngeal cancer. AB - Background: Early-stage oropharyngeal squamous cell carcinoma (OPSCC) can currently be treated by surgical resection or definitive radiotherapy (RT). The aim of this study is to review the outcomes of early-stage OPSCC submitted to surgery or primary RT. Preliminary results have shown similar overall survival (OS) and locoregional recurrence-free survival (LRFS). Material/Methods: Retrospective study of patients with cT1-T2 cN0-N1 OPSCC, diagnosed between January 2009 and December 2014, treated with surgery or primary RT. Results: 61 patients with cT1-T2 cN0-N1 OPSCC were included. Forty-two (69%) were submitted to surgical resection, of which 37 (88%) had adjuvant treatment (24 received RT and 13 chemoradiotherapy). Nineteen (31%) were treated with primary RT, and 3 of them had concurrent chemotherapy. RT was given with intensity-modulated radiation therapy (IMRT) (71%) or three-dimensional conformal radiation therapy (3D-CRT) (29%). At a median follow-up of 5.4 years, there were 3 tumor persistences, 5 local failures, 2 regional failures and no distant metastasis. The 3-year and 5 year OS were 77% and 71% in the RT group vs. 71% and 59% in the surgery group, respectively (HR 0.60, 95% CI 0.22-1.61; p = 0.30). The 3-year and 5-year LRFS were 71% and 64% in the RT group vs. 66% and 50% in the surgery group, respectively (HR 0.59, 95% CI 0.24-1.45; p = 0.24). Up to 34% had acute grade 3 toxicity and 11% had grade 4 osteoradionecrosis of the jaw. Conclusions: Longer follow-up still does not show a significant difference in OS and LRFS between both treatments. Because most patients submitted to surgery required adjuvant RT and since its side-effects were not negligible, further studies are warranted to better suit the first treatment for each patient and to prevent the need for adjuvant treatment and the risk of toxicity. PMID- 29594247 TI - Do protons and X-rays induce cell-killing in human peripheral blood lymphocytes by different mechanisms? AB - Purpose: Significant progress has been made in the technological and physical aspects of dose delivery and distribution in proton therapy. However, mode of cell killing induced by protons is less understood in comparison with X-rays. The purpose of this study is to see if there is any difference in the mode of cell killing, induced by protons and X-rays in an ex vivo human peripheral blood lymphocyte (HPBL) model. Materials and methods: HPBL were irradiated with 60 MeV proton beam or 250-kVp X-rays in the dose range of 0.3-4.0 Gy. Frequency of apoptotic and necrotic cells was determined by the Fluorescein (FITC)-Annexin V labelling procedure, 1 and 4 h after irradiation. Chip-based DNA Ladder Assay was used to confirm radiation-induced apoptosis and necrosis. Chip-based DNA Ladder Assay was used to confirm radiation-induced apoptosis. Results: Ex vivo irradiation of HPBL with proton beams of 60 MeV or 250 kVp X-rays resulted in apoptotic as well as necrotic modes of cell-killing, which were evident at both 1 and 4 h after irradiation in the whole dose and time range. Generally, our results indicated that protons cause relatively higher yields of cell death that appears to be necrosis compared to X-rays. The analysis also demonstrates that radiation type and dose play a critical role in mode of cell-killing. Conclusion: Obtained results suggest that X-rays and protons induce cell-killing by different modes. Such differences in cell-killing modes may have implications on the potential of a given therapeutic modality to cause immune modulation via programmed cell death (X-rays) or necrotic cell death (proton therapy). These studies point towards exploring for gene expression biomarkers related necrosis or apoptosis to predict immune response after proton therapy. PMID- 29594248 TI - Analysis of pseudoprogression after proton or photon therapy of 99 patients with low grade and anaplastic glioma. AB - Background and purpose: Proton therapy is increasingly used to treat primary brain tumors. There is concern for higher rates of pseudoprogression (PsP) after protons compared to photons. The purposes of this study are to compare the rate of PsP after proton vs. photon therapy for grade II and III gliomas and to identify factors associated with the development of PsP. Materials and methods: Ninety-nine patients age >18 years with grade II or III glioma treated with photons or protons were retrospectively reviewed. Demographic data, IDH and 1p19q status, and treatment factors were analyzed for association with PsP, progression free survival (PFS), and overall survival (OS). Results: Sixty-five patients were treated with photons and 34 with protons. Among those with oligodendroglioma, PsP developed in 6/42 photon-treated patients (14.3%) and 4/25 proton-treated patients (16%, p = 1.00). Among those with astrocytoma, PsP developed in 3/23 photon-treated patients (13%) and 1/9 proton-treated patients (11.1%, p = 1.00). There was no difference in PsP rate based on radiation type, radiation dose, tumor grade, 1p19q codeletion, or IDH status. PsP occurred earlier in oligodendroglioma patients treated with protons compared to photons, 48 days vs. 131 days, p < .01. On multivariate analyses, gross total resection (p = .03, HR = 0.48, 95%CI = 0.25-0.93) and PsP (p = .04, HR = 0.22, 95% CI = 0.05-0.91) were associated with better PFS; IDH mutation was associated with better OS (p < .01, HR = 0.22, 95%CI = 0.08-0.65). Conclusions: Patients with oligodendroglioma but not astrocytoma develop PsP earlier after protons compared to photons. PsP was associated with better PFS.

PMID- 29594250 TI - Anti PD-L1 DUrvalumab combined with Cetuximab and RadiOtherapy in locally advanced squamous cell carcinoma of the head and neck: A phase I/II study (DUCRO). AB - Introduction and background: Head and neck squamous cell carcinoma (HNSCC) has been increasingly recognized as an immune suppressive malignancy. The efficacy of immune checkpoint inhibitors (ICI's) in the context of recurrent/metastatic (R/M) setting anticipates the possible integration of immunotherapy into the therapeutic armamentarium of locally advanced disease. Durvalumab (DUR) is a humanized monoclonal IgG1, anti-PD-L1 antibody with promising data in R/M HNSCC. The aim of our study is to test the antitumor activity of a combined regimen incorporating an immune checkpoint inhibitor into a conventional bio-radiation strategy for the cure of unfavorable locally advanced HNSCC. Methods/design: In this open label, multi-center, single-arm, phase I/II study, enrolled patients will receive Radiotherapy (RT) (69.9 Gy/2.12 Gy in 33 fractions) with concurrent Cetuximab (CTX) (400 mg/m2 1 week before RT start followed by 250 mg/m2 weekly) and DUR (fixed dose of 1500 mg every 4 weeks starting from RT-CTX week 1) followed by adjuvant DUR (to a maximum of 6 months after completion of RT-CTX). Primary endpoint of the study is 2-year progression-free survival (PFS). A safety run-in is planned after the enrollment of first 12, 24 and 36 patients. Patients affected by high-risk (>=N2a or >=T3, any N) larynx, hypopharynx and HPV negative oropharynx or HPV-positive oropharynx (>=T2, >=N2b, >=10 pack/years) will be eligible. Discussion: Conventional intensification strategies failed to provide any benefit for the cure of locally advanced HNSCC. For the still prevalent HPV negative population and the high risk-HPV positive disease, there is an unmet need for alternative treatment paradigms. Potentially, the inhibition of the PD 1/PD-L1 checkpoint may synergize with both CTX and RT through immunologic interplay, ultimately aiming to reverse the HNSCC-induced immune suppression. The DUCRO study will seek to demonstrate if such a strategy may be safe and active. Trial registration: NCT number: NCT03051906Eudract number: 2016-004668-20.

AB - Introduction: Radiotherapy education can be very different across Europe, despite the publication of the ESTRO core curricula in 2011. The purpose of the current study is to map the different RO European education systems, to report their perceived quality and to understand what could be improved to better teach RO. Methods: An online survey consisting of 30 questions was sent to RO professionals under 40 years of age via email and social media. Clinicians, radiobiologists, physicists and radiation therapists (RTTs) were invited to answer questions regarding (1) demographics data, (2) duration, (3) organization, (4) content, (5) quality and potential improvements of national education programs. Results: Four hundred and sixty three questionnaires were received from 34 European countries. All disciplines were represented: 45% clinicians (n = 210), 29% physicists (n = 135), 24% RTTs (n = 108) and 2% radiobiologists (n = 10). Male and female participants were well-balanced in each speciality, except for radiobiologists (80% males). Median age was 31.5 years old (range 21-40). A large range of the duration of the National RO education programs was observed: median = 9 years (range: 3-15). In half of the surveyed countries the European Credit Transfer System (ECTS), that facilitates mobility for trainees, has been implemented. Participants declared only a minority of countries have implemented the ESTRO Core Curriculum (n = 5). A quarter of participants indicated that their national education program is insufficient. Conclusion: This is the first study to examine the different RO education systems in Europe. Large differences in organization and duration of national education programs have been found, along with perceived quality across Europe within each speciality. These results show the necessity of a discussion on how to move forward in this diversity of education programs and the potential contribution that the ESTRO may fulfil. PMID- 29594253 TI - Improved outcome of treating locally advanced lung cancer with the use of Lattice Radiotherapy (LRT): A case report. AB - The Lattice Radiotherapy (LRT) technique is mainly based on the GRID technology with the improved feature of the 3D treatment delivery. A 72 year old male presented with left shoulder pain due to a 6 cm pulmonary mass in the left upper lobe (LUL) histologically proven Non-Small Cell Lung Cancer (NSCLC) stage IIIA. In July 2011 he was treated in our center with LRT followed by conventional fractionated Volumetric Modulated Arc Therapy (VMAT) combined with chemotherapy. Clinical and imaging follow up of 6 years demonstrated continued improvement and the patient is currently with no evidence of disease (NED). This outstanding result obtained in our first lung cancer patient treated with this approach corroborates its potential in the treatment of locally advanced lung cancer. In a period of 7 years we have treated more than 30 patients with LRT for different diagnosis and sites; 12 of them NSCLC patients, with markedly improved local control and minimal toxicity. PMID- 29594251 TI - The EMBRACE II study: The outcome and prospect of two decades of evolution within the GEC-ESTRO GYN working group and the EMBRACE studies. AB - The publication of the GEC-ESTRO recommendations one decade ago was a significant step forward for reaching international consensus on adaptive target definition and dose reporting in image guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer. Since then, IGABT has been spreading, particularly in Europe, North America and Asia, and the guidelines have proved their broad acceptance and applicability in clinical practice. However, a unified approach to volume contouring and reporting does not imply a unified administration of treatment, and currently both external beam radiotherapy (EBRT) and IGABT are delivered using a large variety of techniques and prescription/fractionation schedules. With IGABT, local control is excellent in limited and well-responding tumours. The major challenges are currently loco-regional control in advanced tumours, treatment-related morbidity, and distant metastatic disease. Emerging evidence from the RetroEMBRACE and EMBRACE I studies has demonstrated that clinical outcome is related to dose prescription and technique. The next logical step is to demonstrate excellent clinical outcome with the most advanced EBRT and brachytherapy techniques based on an evidence-based prospective dose and volume prescription protocol. The EMBRACE II study is an interventional and observational multicentre study which aims to benchmark a high level of local, nodal and systemic control while limiting morbidity, using state of the art treatment including an advanced target volume selection and contouring protocol for EBRT and brachytherapy, a multi-parametric brachytherapy dose prescription protocol (clinical validation of dose constraints), and use of advanced EBRT (IMRT and IGRT) and brachytherapy (IC/IS) techniques (clinical validation). The study also incorporates translational research including imaging and tissue biomarkers.

AB - The methods currently employed for in vivo site-directed mutagenesis in yeast are laborious and/or inefficient. Recent developments of the CRISPR-based approaches hold great promise for genome editing, but its application in the yeast S. cerevisiae remains a time-consuming affair. The rate-limiting step in CRISPR mediated genetic engineering in yeast is the incorporation of the guide sequences, which target Cas9 to relevant chromosomal locus, into the relevant yeast vectors. Here we present a PCR-based strategy to introduce specific point mutation into the yeast CDC48 gene via CRISPR. Our method eliminates the need for special dam- strain and markedly shortens the elaborate multi-step cloning process, leading to significant savings in time, labor and cost. PMID- 29594255 TI - Enhanced Expression of the Key Mitosis Regulator Cyclin B1 Is Mediated by PDZ Binding Kinase in Islets of Pregnant Mice. AB - The proliferation of pancreatic beta cells is enhanced to enable an increase in beta-cell mass and to compensate for insulin resistance during pregnancy. To elucidate the mechanisms involved, we previously investigated islets from pregnant and nonpregnant mice by gene expression profiling and found that the expression of postsynaptic density-95/Discs large/zonula occludens-1 (PDZ) binding kinase (Pbk), a member of the mitogen-activated protein kinase kinase family, is increased in pregnant mouse islets compared with control mouse islets. Among the pregnancy hormones, treatment with estradiol upregulated Pbk expression. Inhibition of Pbk expression using a small interfering RNA for Pbk reduced bromodeoxyuridine incorporation in mouse insulinoma 6 cells, which was accompanied by a decreased expression of Ccnb1, a regulatory gene involved in mitosis. Ccnb1 expression was augmented in mouse islets during pregnancy. The forced expression of Pbk using an adenovirus system in isolated mouse islets increased Ccnb1 expression, and the Pbk inhibitor HI-TOPK-032 suppressed Ccnb1 expression in islets isolated from pregnant mice. Our results suggest that Pbk contributes to the expansion of islets during pregnancy and that Ccnb1 may assist Pbk in its role in beta-cell proliferation. PMID- 29594256 TI - From Consternation to Revelation: Discovery of a Role for IGSF1 in Pituitary Control of Thyroid Function. AB - Immunoglobulin superfamily, member 1 (IGSF1) is a transmembrane glycoprotein highly expressed in the mammalian pituitary gland. Shortly after its discovery in 1998, the protein was proposed to function as a coreceptor for inhibins (and was even temporarily renamed inhibin binding protein). However, subsequent investigations, both in vitro and in vivo, failed to support a role for IGSF1 in inhibin action. Research on IGSF1 nearly ground to a halt until 2011, when next generation sequencing identified mutations in the X-linked IGSF1 gene in boys and men with congenital central hypothyroidism. IGSF1 was localized to thyrotrope cells, implicating the protein in pituitary control of the thyroid. Investigations in two Igsf1 knockout mouse models converged to show that IGSF1 deficiency leads to reduced expression of the receptor for thyrotropin-releasing hormone (TRH) and impaired TRH stimulation of thyrotropin secretion, providing a candidate mechanism for the central hypothyroidism observed in patients. Nevertheless, the normal functions of IGSF1 in thyrotropes and other cells remain unresolved. Moreover, IGSF1 mutations are also commonly associated with other clinical phenotypes, including prolactin and growth hormone dysregulation, and macroorchidism. How the loss of IGSF1 produces these characteristics is unknown. Although early studies of IGSF1 ran into roadblocks and blind alleys, armed with the results of detailed clinical investigations, powerful mouse models, and new reagents, the field is now poised to discover IGSF1's function in endocrine tissues, including the pituitary and testes. PMID- 29594257 TI - Plasma IL-1 Receptor Antagonist Concentration Has an Inverse Association With Birth Weight in Prepubertal Children. AB - Context: Birth size has an impact on later cardiometabolic risk that is strongly related to low-grade inflammation. Objective: To evaluate plasma interleukin-1 receptor antagonist (IL-1ra) concentrations in relation to birth size and cardiometabolic and inflammatory markers in prepubertal children. Design: A cohort study. Anthropometric data were recorded. Fasting blood samples were collected for plasma analyses of IL-1ra, alanine transaminase, total cholesterol, high- and low-density lipoprotein cholesterols, triglyceride, glucose, and serum analyses of 25-hydroxyvitamin D [25(OH)D] and high-sensitivity C-reactive protein (hs-CRP) concentrations. Participants: Forty-nine large for gestational age (LGA), 56 appropriate for gestational age, and 23 small for gestational age (SGA) children at 5 to 8 years of age were examined. Main Outcome Measures: Differences in IL-1ra concentrations among the birth-size groups and associations between IL 1ra and other metabolic markers were assessed. Results: Body mass index (BMI) standard deviation score (SDS)-adjusted plasma IL-1ra concentrations were highest in the SGA- and lowest in the LGA-born children (P = 0.015). Age- and sex adjusted IL-1ra concentrations had strongest associations with BMI SDS (P < 0.001) and hs-CRP (P < 0.001, also when further adjusted for BMI SDS). Conclusions: Prepubertal children born SGA had the highest and those born LGA the lowest IL-1ra concentrations in this study cohort. Most associations found between IL-1ra and the studied metabolic parameters were weight related, but the association with hs-CRP remained strong after adjustment for BMI. It seems that at prepuberty, SGA children have a stronger inflammatory state than LGA children and may thus be at a greater risk for later metabolic disturbances. PMID- 29594258 TI - Elevated (Pro)renin Receptor Expression Contributes to Maintaining Aerobic Metabolism in Growth Hormone Deficiency. AB - Context: Growth hormone deficiency (GHD) leads to obesity and may induce tissue hypoxia. As (pro)renin receptor [(P)RR] is reported to contribute to the aerobic metabolism by stabilizing pyruvate dehydrogenase (PDH), it may play a substantial role in GHD. Objective: We aimed to investigate serum soluble (P)RR [s(P)RR] concentration, the origin of s(P)RR, and significance of (P)RR in GHD. Design Setting and Participants: Serum s(P)RR concentration was examined in 72 patients with pituitary diseases, including 32 patients with severe GHD (SGHD) and after GH replacement in 16 SGHD patients. Leptin-deficient ob/ob obese mice were treated with pegvisomant, a GH receptor antagonist, to explore the source of elevated serum s(P)RR in GHD. Adipocytes were cultured with 5% O2 to examine the effects of hypoxia. Results: Serum s(P)RR concentration was higher in patients with SGHD than in those without SGHD. Obesity was the important determinant of s(P)RR concentration. Serum s(P)RR concentration significantly decreased after GH replacement in SGHD patients. (P)RR mRNA expression was increased specifically in the adipose tissue (AT) of pegvisomant-treated obese mice compared with that of control obese mice. Hypoxia in cultured adipocytes increased (P)RR expression without affecting the PDH E1 beta subunit (PDHB) expression; however, with (P)RR knockdown by small interfering RNA, hypoxia significantly decreased the expression of PDHB. Conclusion: GHD patients showed increased serum s(P)RR concentration, possibly caused by obesity and hypoxia. (P)RR expression in AT of GHD patients may be elevated to help maintain aerobic metabolism under hypoxia. Thus, the elevated serum s(P)RR level may reflect hypoxia in ATs. PMID- 29594259 TI - 17beta-Estradiol and ICI182,780 Differentially Regulate STAT5 Isoforms in Female Mammary Epithelium, With Distinct Outcomes. AB - Prolactin (PRL) and estrogen cooperate in lobuloalveolar development of the mammary gland and jointly regulate gene expression in breast cancer cells in vitro. Canonical PRL signaling activates STAT5A/B, homologous proteins that have different target genes and functions. Although STAT5A/B are important for physiological mammary function and tumor pathophysiology, little is known about regulation of their expression, particularly of STAT5B, and the consequences for hormone action. In this study, we examined the effect of two estrogenic ligands, 17beta-estradiol (E2) and the clinical antiestrogen, ICI182,780 (ICI, fulvestrant) on expression of STAT5 isoforms and resulting crosstalk with PRL in normal and tumor murine mammary epithelial cell lines. In all cell lines, E2 and ICI significantly increased protein and corresponding nascent and mature transcripts for STAT5A and STAT5B, respectively. Transcriptional regulation of STAT5A and STAT5B by E2 and ICI, respectively, is associated with recruitment of estrogen receptor alpha and increased H3K27Ac at a common intronic enhancer 10 kb downstream of the Stat5a transcription start site. Further, E2 and ICI induced different transcripts associated with differentiation and tumor behavior. In tumor cells, E2 also significantly increased proliferation, invasion, and stem cell-like activity, whereas ICI had no effect. To evaluate the role of STAT5B in these responses, we reduced STAT5B expression using short hairpin (sh) RNA. shSTAT5B blocked ICI-induced transcripts associated with metastasis and the epithelial mesenchymal transition in both cell types. shSTAT5B also blocked E2 induced invasion of tumor epithelium without altering E2-induced transcripts. Together, these studies indicate that STAT5B mediates a subset of protumorigenic responses to both E2 and ICI, underscoring the need to understand regulation of its expression and suggesting exploration as a possible therapeutic target in breast cancer. PMID- 29594260 TI - Endocrine Disorders in Primary Mitochondrial Disease. AB - Context: Endocrine disorders are common in individuals with mitochondrial disease. To develop evidence-based screening practices in this high-risk population, updated age-stratified estimates of the prevalence of endocrine conditions are needed. Objective: To measure the point prevalence of selected endocrine disorders in individuals with mitochondrial disease. Design Setting and Patients: The North American Mitochondrial Disease Consortium Patient Registry is a large, prospective, physician-curated cohort study of individuals with mitochondrial disease. Participants (n = 404) are of any age, with a diagnosis of primary mitochondrial disease confirmed by molecular genetic testing. Main Outcome Measures: Age-specific prevalence of diabetes mellitus (DM), abnormal growth and sexual maturation (AGSM), hypoparathyroidism, and hypothyroidism. Results: The majority of our sample was pediatric (<18 years; 60.1%), female (56.9%), and white (85.9%). DM affected 2% of participants aged <18 years [95% confidence interval (CI): 0.4% to 5.7%] and 24.4% of adult participants (95% CI: 18.6% to 30.9%). DM prevalence was highest in individuals with mitochondrial encephalomyopathy, lactic acidosis, and strokelike episodes syndrome (MELAS; 31.9%, of whom 86.2% had the m.3243A>G mutation). DM occurred more often with mitochondrial DNA defects (point mutations and/or deletions) than with nuclear DNA mutations (23.3% vs 3.7%, respectively; P < 0.001). Other prevalence estimates were 44.1% (95% CI: 38.8% to 49.6%) for AGSM; 0.3% (95% CI: 0% to 1.6%) for hypoparathyroidism; and 6.3% (95% CI: 4% to 9.3%) for hypothyroidism. Conclusion: DM and AGSM are highly prevalent in primary mitochondrial disease. Certain clinical mitochondrial syndromes (MELAS and Kearns-Sayre/Pearson syndrome spectrum disorders) demonstrated a higher burden of endocrinopathies. Clinical screening practices should reflect the substantial prevalence of endocrine disorders in mitochondrial disease. PMID- 29594261 TI - Early Detection of Rapid Cystic Fibrosis Disease Progression Tailored to Point of Care: A Proof-of-Principle Study. AB - Slowing cystic fibrosis (CF) lung disease progression is crucial to survival, but point-of-care technologies aimed at early detection-and possibly prevention-of rapid lung function decline are limited. This proof-of-principle study leverages a rich national patient registry and follow-up data on a local CF cohort to build an algorithm and prototype prognostic tool aimed at early detection of rapid lung function decline. The algorithm was developed using a novel longitudinal analysis of lung function (measured as forced expiratory volume in 1 s of % predicted, FEV1). Covariates included clinical and demographic characteristics selected from the registry based on information criterion. Preliminary assessment of algorithm performance suggested excellent predictive accuracy and earlier detection of rapid decline than standard of care being applied at a local center. Graphical displays were presented and evaluated for clinical utility. Predictions from the algorithms and chosen graphical displays were translated into a prototype web application using RShiny and underwent iterative development based on clinician feedback. This paper suggests that the algorithm and its translation could offer a means for earlier detection and treatment of rapid decline, providing clinicians with a viable point-of-care technology to intervene prior to irreversible lung damage. PMID- 29594262 TI - Multi-Atlas Based Segmentation of Brainstem Nuclei from MR Images by Deep Hyper Graph Learning. AB - Accurate segmentation of brainstem nuclei (red nucleus and substantia nigra) is very important in various neuroimaging applications such as deep brain stimulation and the investigation of imaging biomarkers for Parkinson's disease (PD). Due to iron deposition during aging, image contrast in the brainstem is very low in Magnetic Resonance (MR) images. Hence, the ambiguity of patch-wise similarity makes the recently successful multi-atlas patch-based label fusion methods have difficulty to perform as competitive as segmenting cortical and sub cortical regions from MR images. To address this challenge, we propose a novel multi-atlas brainstem nuclei segmentation method using deep hyper-graph learning. Specifically, we achieve this goal in three-fold. First, we employ hyper-graph to combine the advantage of maintaining spatial coherence from graph-based segmentation approaches and the benefit of harnessing population priors from multi-atlas based framework. Second, besides using low-level image appearance, we also extract high-level context features to measure the complex patch-wise relationship. Since the context features are calculated on a tentatively estimated label probability map, we eventually turn our hyper-graph learning based label propagation into a deep and self-refining model. Third, since anatomical labels on some voxels (usually located in uniform regions) can be identified much more reliably than other voxels (usually located at the boundary between two regions), we allow these reliable voxels to propagate their labels to the nearby difficult-to-label voxels. Such hierarchical strategy makes our proposed label fusion method deep and dynamic. We evaluate our proposed label fusion method in segmenting substantia nigra (SN) and red nucleus (RN) from 3.0 T MR images, where our proposed method achieves significant improvement over the state-of-the-art label fusion methods. PMID- 29594263 TI - Tandem trapped ion mobility spectrometry. AB - There is currently a strong interest in the use of ion mobility spectrometry-mass spectrometry (IMS-MS) instrumentation for structural biology. In these applications, momentum transfer cross sections derived from IMS-MS measurements are used to reconstruct the three-dimensional analyte structure. Recent reports indicate that additional structural information can be extracted from measuring changes in cross sections in response to changes of the analyte structure. To further this approach, we constructed a tandem trapped IMS analyser (TIMS-TIMS) and incorporated it in a QqTOF mass spectrometer. TIMS-TIMS is constructed by coupling two TIMS analysers via an "interface region" composed of two apertures. We show that peptide oligomers (bradykinin) and native-like protein (ubiquitin) ions can be preserved through the course of an experiment in a TIMS-TIMS analyser. We demonstrate the ability to collisionally-activate as well as to trap mobility-selected ions, followed by subsequent mobility-analysis. In addition to inducing conformational changes, we show that we can fragment low charge states of ubiquitin at >1 mbar between the TIMS analysers with significant sequence coverage. Many fragment ions exhibit multiple features in their TIMS spectra, which means that they may not generally exist as the most stable isomer. The ability of TIMS-TIMS to dissociate mobility-selected protein ions and to measure the cross sections of their fragment ions opens new possibilities for IMS-based structure elucidation.

AB - The specificity of carbohydrate transporters towards their substrates poses a significant challenge for the development of molecular probes to monitor sugar uptake in cells for biochemical and biomedical applications. Herein we report a new set of coumarin-based fluorescent sugar conjugates applicable for the analysis of fructose uptake due to their free passage through the fructose specific transporter GLUT5. The reported probes cover a broad range of the fluorescence spectrum providing essential tools for the evaluation of fructose transport capacity in live cells. PMID- 29594269 TI - Nano X-ray diffractometry device for nanofluidics. AB - Nanofluidics is gaining attention because it has unique liquid and fluidic properties that are not observed in microfluidics. It has been reported that many liquid properties change when the size of a fluidic channel is reduced below 500 800 nm. To discuss the underlying mechanism, information on the microscopic liquid structure must be obtained (e.g., by X-ray diffractometry). However, the very small volume (attoliters to femtoliters) of a nanochannel and the large volume of its glass substrate prevent measurement of signals from the nanochannel liquid. In this study, we report a novel nanofluidic device that can be used in conjunction with X-ray diffractometry to analyze the structure of water confined in nanochannels. Top-down and bottom-up micro- and nano-fabrication processes were established, and the substrate thickness of the measurement area was reduced to only 2.7 MUm, which was almost 1000 times smaller than that of conventional substrates (millimeter scale). With this new device, X-ray diffraction signals were clearly observed in nanochannels 500 nm wide and deep. Based on the X-ray diffraction pattern, the radial distribution function was calculated, which showed a structure nearly similar to that of a bulk sample. Therefore, X-ray diffractometry in nanochannels was realized. This method will provide important information on how a liquid behaves when confined in a nanospace and contribute to chemistry and biology on scales of 10-100 nm (e.g., inter- and intra-cellular spaces). It is also important for designing chemical reactions and fluidic circuits in nanochannels for realizing highly functional devices. PMID- 29594270 TI - Synthesis of ultrathin Ni nanosheets for semihydrogenation of phenylacetylene to styrene under mild conditions. AB - The synthesis of ultrathin metal nanosheets (NSs) attracts broad scientific and technological interest, and it still remains a challenge for non-noble metals like nickel due to their intrinsic cubic symmetry and high surface energy. Herein, we report a NiO intermediated solvothermal method towards the synthesis of ultrathin Ni NSs (thickness < 3 nm) using N,N-dimethylformamide as the solvent and n-butylamine as the shape controlling reagent. The growth of the ultrathin Ni NSs follows an intermediate mechanism which was proved by the results obtained by means of transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray absorption spectra (XAS) and X-ray photoelectron spectroscopy (XPS). Under solvothermal conditions, the nickel acetylacetonate precursor was first reduced to a NiO NS intermediate, then reduction occurred and NiO NSs were reduced to Ni NSs. The synthesized ultrathin Ni NSs predominately in a metallic state showed high selectivity (88.0-92.0%) towards styrene (ST) in the phenylacetylene (PA) semihydrogenation reaction under mild conditions (323 K, 1 atm of hydrogen) in a broad PA conversion range (2.0-98.0%). The low coverage of oxygen atoms on the Ni NS surface is proposed to account for the high ST selectivity, as indicated by density functional theory (DFT) calculations.

AB - A self-assembly technology allows metal-organic framework materials to constitute a honeycomb internal structure while being shaped into millimeter-scale spheres. The ZIF-8 load is up to 83 wt% through solidification of chitosan (CS). This approach can be expanded to other morphologies (fibers) or crystals and is transformative for industrial manufacturing of nanomaterials. PMID- 29594272 TI - Terpyridine-based metallosupramolecular constructs: tailored monomers to precise 2D-motifs and 3D-metallocages. AB - This overview represents a comprehensive summary of the recent developments in the growing field of terpyridine-based, discrete metallosupramolecular architectures. The N-heteroaromatic ligand [2,2':6',2'']terpyridine (tpy) presents a convergent N,N',N''-chelating donor set and has the ability to bind diverse metal ions to form stable pseudo-octahedral tpy-M2+-tpy bonds. Use of tpy M2+-tpy connectivity for the edges and directed organic vertices has opened the door to diverse, dynamic, utilitarian macromolecular materials. New strategies have been employed to synthesize a range of 2D- and 3D-fractals as well as novel macrocyclic constructs by employing new designer strategies, such as: triangle based frameworks, hexagonal fractal designs, flexible polyterpyridine linkers, and noncovalent interactions for spontaneous quantitative self-assembly. Numerous examples of heteroleptic self-assembly have been described along with the synthesis of heterometallic conjugates using step-wise protocols. Utilizing multiplanar, directed spacer units in the polyterpyridine vertices, new 3D polyhedra were obtained facilitating the assembly of hybrid fractal-dendritic materials. These constructs are shown to undergo tunable conformational transformations by responding to specific stimuli such as concentration, temperature, and counter ions. The increasing ability to exploit hierarchical self-assembly of complex, higher order supramolecular nanomaterials is discussed. PMID- 29594273 TI - The impact of galactooligosaccharides on the bioaccessibility of sterols in a plant sterol-enriched beverage: adaptation of the harmonized INFOGEST digestion method. AB - The effect of the addition of galactooligosaccharides (GOS) on sterol bioaccessibility in three plant sterol (PS)-enriched milk-based fruit beverages (without GOS addition (MfB) and with 2.5 g (MfB-G2) and 5.0 g (MfB-G5) GOS per 250 mL) was evaluated after micellar gastrointestinal digestion. Cholesterol bioaccessibility was very similar among beverages, though a slight significant increase (from 80% to 85%) was observed by the addition of 5.0 g GOS. The addition of GOS did not affect total PS bioaccessibility (~37%). Based on the results obtained after micellar digestion, it has been demonstrated that these beverages could be a suitable food matrix for simultaneous enrichment with PS and GOS. The harmonized in vitro digestion model INFOGEST was applied to the MfB beverage, but the cholesterol content could not be quantified due to its contribution of bile salts. Hence, it was proposed: (i) a change in porcine bile salt concentration from 10 mM to 1.4 mM (in order to compare with micellar digestion); or (ii) a change of bile salt origin (bovine instead of porcine), maintaining physiological concentration (10 mM, INFOGEST condition). Both options allowed cholesterol quantification, with bioaccessibilities of 62% (reduction of bile salts) and 38% (replacement of the bile salt source), whereas plant sterol bioaccessibilities were 22% and 14%, respectively. Therefore, the change of bile salt origin maintaining INFOGEST concentration is proposed as a method to evaluate sterol (cholesterol and PS) bioaccessibility in these beverages, demonstrating the need for the selection of appropriate conditions of the INFOGEST harmonized method according to the food matrix and compounds to be determined. PMID- 29594275 TI - Oligothienyl catenated germanes and silanes: synthesis, structure, and properties. AB - The synthesis of two new groups of oligothienyl catenated silanes and germanes, Me5M2Thn (1a-b), Me5M2ThnM2Me5 (2a-c) (terminal), and ThnM2Me4Thn (3a-d) (internal) (M = Si, Ge; n = 2, 3; Th = 2- or 2,5-thienyl), is reported. The study of their structural parameters as well as of their spectral (NMR), electrochemical (CV) and optical (UV/vis absorbance, luminescence) properties has been performed in detail; in addition, the unexpected compound [Th2Si2Me4Th]2 (3a') is also studied. Theoretical investigations have been performed for model compounds in order to establish structure-property relationships. The molecular structures of 2a (Me5Si2Th2Si2Me5), 2b (Me5Ge2Th2Ge2Me5), 3a (Th2Si2Me4Th2) and 3b (Th2Ge2Me4Th2) have been investigated by X-ray diffraction analysis. An effective conjugation with flattening of both Th planes in terminal 2a and 2b was observed. The main trends in the dependence of the optical and electrochemical properties on the structural parameters have been established. All of the compounds studied exhibit a strong emission within the 378-563 nm range, and the maximal quantum yield (up to 77%) is observed for the Si derivative 3a'. For the majority of the compounds, the quantum yields (20-30%) are significantly larger than for 2,2'-bi- and 2,2':5',5''-terthiophenes. Due to their good emission properties, these compounds could be used to develop new materials with specific spectral properties. PMID- 29594274 TI - Luminescence mechanisms of ultrasmall gold nanoparticles. AB - The past decade has witnessed a burst of study on ultrasmall gold nanoparticles. Unlike semiconductor quantum dots, ultrasmall gold nanoparticles have very diverse emission mechanisms, which are often involved in many structural factors such as size, valence state, surface ligands and crystallinity. In this frontier, we summarize our latest advancement in the fundamental understanding of emission mechanisms of ultrasmall gold nanoparticles, which are expected to help us more precisely control their emissions and broaden their applications from energy technologies to disease detection. PMID- 29594276 TI - Defect engineering in 1D Ti-W oxide nanotube arrays and their correlated photoelectrochemical performance. AB - Understanding the nature of interfacial defects of materials is a critical undertaking for the design of high-performance hybrid electrodes for photocatalysis applications. Theoretical and computational endeavors to achieve this have touched boundaries far ahead of their experimental counterparts. However, to achieve any industrial benefit out of such studies, experimental validation needs to be systematically undertaken. In this sense, we present herein experimental insights into the synergistic relationship between the lattice position and oxidation state of tungsten ions inside a TiO2 lattice, and the respective nature of the created defect states. Consequently, a roadmap to tune the defect states in anodically-fabricated, ultrathin-walled W-doped TiO2 nanotubes is proposed. Annealing the nanotubes in different gas streams enabled the engineering of defects in such structures, as confirmed by XRD and XPS measurements. While annealing under hydrogen stream resulted in the formation of abundant Wn+ (n < 6) ions at the interstitial sites of the TiO2 lattice, oxygen- and air-annealing induced W6+ ions at substitutional sites. EIS and Mott-Schottky analyses indicated the formation of deep-natured trap states in the hydrogen annealed samples, and predominantly shallow donating defect states in the oxygen- and air-annealed samples. Consequently, the photocatalytic performance of the latter was significantly higher than those of the hydrogen-annealed counterparts. Upon increasing the W content, photoelectrochemical performance deteriorated due to the formation of WO3 crystallites that hindered charge transfer through the photoanode, as evident from the structural and chemical characterization. To this end, this study validates the previous theoretical predictions on the detrimental effect of interstitial W ions. In addition, it sheds light on the importance of defect states and their nature for tuning the photoelectrochemical performance of the investigated materials. PMID- 29594278 TI - Room-temperature distance measurements using RIDME and the orthogonal spin labels trityl/nitroxide. AB - Electron paramagnetic resonance (EPR) based nanometer distance measurements at ambient temperatures are of particular interest for structural biology applications. The nitroxide spin labels commonly used in EPR reveal relatively short transverse relaxation under these conditions, which limits their use for detecting static dipolar interactions. At the same time, the longitudinal relaxation of nitroxide spin labels is still long enough to allow using them as 'pumped' species in the relaxation induced dipolar modulation enhancement (RIDME) experiment where the detection is carried out on the slower relaxing triarylmethyl (TAM) spin labels. In the present study, we report the first demonstration of room-temperature RIDME distance measurements in nucleic acids using TAM as the slow-relaxing detected species and traditional nitroxide as the fast-relaxing partner spin. Two types of immobilizers, glassy trehalose and the modified silica gel Nucleosil, were used for immobilization of the spin-labeled biomolecules. The room-temperature RIDME-based distance distributions are in good agreement with those measured at 80 K by other techniques. Room-temperature RIDME on the spin pairs trityl/nitroxide may become a useful method for the structural characterization of biomacromolecules and biomolecular complexes at near physiological temperatures.

AB - The binuclear Cu2+ complex of a pyridinophane polyamine ligand ranking amongst the fastest SOD mimetics so far reported displays a remarkable SOD activity enhancement when grafted to the surface of boehmite (gamma-AlO(OH)) nanoparticles (BNPs). PMID- 29594280 TI - Theoretical study on the origin of activity for the oxygen reduction reaction of metal-doped two-dimensional boron nitride materials. AB - Two-dimensional boron nitride (2D-BN) materials doped with metallic atoms are suitable candidates for the oxygen reduction reaction (ORR) to replace Pt-based catalysts. In this study, a series of model 2D-BN materials doped with metallic atoms were designed to uncover the relationship between ORR activity and metallic dopants. A volcano curve correlation was derived between ORR overpotential and the adsorption free energy values of *OH. Only the doped structures, located at the top of the volcano curve, exhibit optimized activity. Through analyzing the dynamic results, the ORR was found to occur only via the 4e- pathway on Co doped 2D-BN materials with the activation energy of 0.30 eV, which is lower than that achieved with the state-of-the-art Pt-based catalysts (0.79 eV). Furthermore, based on the calculations of electronic structure properties, we find that the small highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gap is more beneficial to the 4e- pathway and prove that the binding strength between metallic atoms-doped 2D-BN materials and oxygenated intermediates is regulated by the HOMO of the metallic dopant consisting non bonding or delocalized orbitals. These results provide an effective method to facilitate the design of new BN-based materials with high electrocatalytic performances besides the ORR performance.

Even very short peptides can self-assemble into structures with a variety of physical and structural characteristics. Remarkably, many peptide assemblies show high catalytic activity in model reactions reaching efficiencies comparable to those found in natural enzymes by weight. In this review, we discuss different strategies used to rationally develop self-assembled peptide catalysts with natural and unnatural backbones as well as with metal-containing cofactors.

AB - Although graphene technology has reached technology readiness level 9 and hydrogen fuel has been identified as a viable futuristic energy resource, pristine atomic layers such as graphene are found to be inactive towards the hydrogen evolution reaction (HER). Enhancing the intrinsic catalytic activity of a material and increasing its number of active sites by nanostructuring are two strategies in novel catalyst development. Here, electrocatalytically inert graphene (G) and hexagonal boron nitride (hBN) are made active for the HER by forming van der Waals (vdW) heterostructures via vertical stacking. The HER studies are conducted using defect free shear exfoliated graphite and hBN modified glassy carbon electrodes via layer by layer sequential stacking. The G/hBN stacking pattern (AA, AB, and AB') and stacking sequence (G/hBN or hBN/G) have been found to play important roles in the HER activity. Enhancement in the intrinsic activity of graphene by the formation of G/hBN vdW stacks has been further confirmed with thermally reduced graphene oxide and hBN based structures. Tunability in the HER performance of the G/hBN vdW stack is also confirmed via a three-dimensional rGO/hBN electrode. HER active sites in the G/hBN vdW structures are then mapped using density functional theory calculations, and an atomistic interpretation has been identified.

AB - We have studied the rheological behavior of the ionic liquid trihexyl(tetradecyl)phosphonium bis(mandelato)borate, [P66614][BMB], and compared it with that of another ionic liquid, namely trihexyl(tetradecyl)phosphonium chloride, [P66614][Cl]. The non-halogenated [P66614][BMB] has been selected as it is known to provide enhanced lubrication performance and is, consequently, of technological importance. The ionic liquid [P66614][Cl], despite its relatively simple anion, exhibits viscosities very similar to those of [P66614][BMB], making it an excellent reference fluid for the modeling study. The viscosities of the ionic liquids have been obtained by equilibrium atomistic simulations using the Green-Kubo relation, and by performing nonequilibrium shear flow simulations. The influence of the simulation system size and a reduction of the atomic charges on the viscosities of the ionic liquids are systematically studied. The atomic charges are reduced to mimic the temperature dependent charge transfer and polarization effects. It has been found that scaling the point charges with factors between 0.60 and 0.80 from full ion charges can provide reliable viscosities of [P66614][BMB], consistent with the experimentally measured viscosities within the studied temperature interval from 373 to 463 K. The viscosities of [P66614][Cl] have been obtained with scaling factors between 0.80 and 1.0 reflecting the lower polarizability and charge transfer effects of the chloride anion. PMID- 29594284 TI - High-performing ultrafast transparent photodetector governed by the pyro phototronic effect. AB - In this work we utilized the advantage of the photo-induced pyroelectric effect - known as "Pyro-phototronic" - to design a self-powered, ultrafast, transparent ultraviolet (UV, 365 nm) photodetector. The device architecture contains an UV absorbing pyroelectric ZnO layer sandwiched between hole-selective V2O5 and a bottom ITO electrode. In addition, the device shows a high optical transmittance, >70%, in the entire visible region. The photo current of the device was enhanced from 19 to 42 MUA under pulsed UV light illumination (lambda = 365 nm, 4 mW cm-2) by exploiting the pyro-phototronic potential. In addition, the photodetector demonstrated ultrafast responses of ~4 MUs for the rise time and ~16 MUs for the fall time. Further, a high photoresponsivity of ~36.34 mA W-1 and excellent photodetectivity of ~6.04 * 1014 Jones, with an enhancement of 725% in both due to the pyroelectric potential, were measured. This novel approach will open a new path to design transparent and ultrafast devices, as well as on the flexible substrates, for future optoelectronic applications.

AB - Endoplasmic reticulum (ER) stress-associated inflammation is a critical molecular mechanism involved in the pathogenesis of endothelial dysfunction (ED). Hence, strategies for alleviating ER stress-induced inflammation may be essential for the prevention of cardiovascular diseases. Paeoniflorin (PF), a bioactive compound from Paeonia lactiflora Pallas is known for its functional properties against vascular inflammation. However, to date, PF-mediated protection against ER stress-dependent inflammation has not been identified. Herein, we investigate the protective effect of PF on lipopolysaccharide (LPS)-stimulated human umbilical vein endothelial cell (HUVEC) injury and explore its underlying mechanism. The result of the cell viability assay indicates that PF promotes the cell survival rate in LPS-stimulated HUVECs. In addition, the LPS-induced over production of inflammatory cytokines (interleukin-6 (IL-6) and monocyte chemotactic protein 1 (MCP-1)) and ER stress markers (78 kDa glucose regulated protein (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP)) are significantly decreased by PF and the ER stress inhibitor 4-phenylbutric acid (4 PBA). The transmission electron microscopy (TEM) assay implies that the ultrastructural abnormalities in ER are reversed by PF treatment, which is similar to the protective effect of 4-PBA. Impressively, we find that the inositol-requiring enzyme 1alpha (IRE1alpha)/nuclear factor-kappa B (NF-kappaB) pathway is significantly activated and contributes to the progress of LPS-induced HUVEC injury by promoting inflammatory cytokine production. IRE1alpha siRNA, AEBSF (ATF6 inhibitor), GSK2656157 (PERK inhibitor), PDTC (NF-kappaB inhibitor) and thapsigargin (TG, IRE1 activator) are used to confirm the role of the IRE1alpha/NF-kappaB pathway in PF-mediated protection against LPS-induced HUVEC injury. Our findings indicate that PF has an inhibitory effect on endothelial injury. To summarize, PF might be a potential therapeutic agent to inhibit ER stress-associated vascular inflammation.

AB - Recently, lead halide perovskites have attracted significant scientific attention in the fields of photovoltaics, light emitting diodes, lasers, photo-detectors and other optoelectronic functional devices. The most stable crystal form of lead halide perovskites is the cube, including nano-cube and micro-cube, which hold great promise as functional materials due to their combination of unique optoelectronic properties and versatility through colloidal synthesis. Herein, we report the solution-processed synthesis of pure inorganic lead halide nano-cubes- and micro-cubes-based colloidal perovskites. The different size of cubes either into nano-cube or micro-cube are demonstrated that their phonon mode transformation which means the perovskite crystal structure phase change cross the nano-cube to micro-cube. The solution-processed colloidal synthesis method and phonon-mode transformation from nano-cube to micro-cube make pure inorganic lead halide perovskite an ideal platform for fundamental optoelectronic studies and the investigation of functional devices. PMID- 29594287 TI - Citrus medica: nutritional, phytochemical composition and health benefits - a review. AB - Citrus medica (Citron) is an underutilized fruit plant having various bioactive components in all parts of the plant. The major bioactive compounds present are iso-limonene, citral, limonene, phenolics, flavonones, vitamin C, pectin, linalool, decanal, and nonanal, accounting for several health benefits. Pectin and heteropolysachharides also play a major role as dietary fibers. The potential impact of citron and its bioactive components to prevent or reverse destructive deregulated processes responsible for certain diseases has attracted different researchers' attention. The fruit has numerous nutraceutical benefits, proven by pharmacological studies; for example, anti-catarrhal, capillary protector, anti hypertensive, diuretic, antibacterial, antifungal, anthelmintic, antimicrobial, analgesic, strong antioxidant, anticancerous, antidiabetic, estrogenic, antiulcer, cardioprotective, and antihyperglycemic. The present review explores new insights into the benefits of citron in various body parts. Throughout the world, citron has been used in making carbonated drinks, alcoholic beverages, syrup, candied peels, jams, marmalade, cordials, and many other value added products, which suggests it is an appropriate raw material to develop healthy processed food. In the present review, the fruit taxonomical classification, beneficial phytochemicals, antioxidant activities, and health benefits are discussed.

AB - Chiral recognition of DNA molecules is important because much evidence has indicated that transformations of chirality and diverse conformations of DNA are involved in a series of key biological events. Among these, enrichment of G quadruplexes (GQs) in the genome, and the exploration of their multiple structures, has aroused great interest. Herein, we compared nearly 100 different sequences with 3'-tail sequences of variable length or different linkers or diverse loops and mutative ionic concentrations. All sequences were capable of forming stable GQs, with fluorescence signal enhancement upon binding with Delta- and Lambda- [Ru(bpy)2(dppz-idzo)]2+ (Delta/Lambda-1). Our results show that multiple factors, including the 3'-tail length, linkers, loop length and ionic concentration, regulate the enantioselectivity of GQs. Furthermore, molecular docking simulations revealed that chiral recognition of GQs depends on the binding site. To the best of our knowledge, this is the first systematic study regarding the regulation of multi-factors for GQ selectivity of chiral Ru complexes. These results will serve as a useful reference for enantioselective recognition of genomic GQs and may facilitate the development of chiral anticancer agents for targeting GQs. PMID- 29594289 TI - Selective growth of chirality-enriched semiconducting carbon nanotubes by using bimetallic catalysts from salt precursors. AB - Bimetallic catalysts play important roles in the selective growth of single walled carbon nanotubes (SWNTs). Using the simple salts (NH4)6W7O24.6H2O and Co(CH3COO)2.4H2O as precursors, tungsten-cobalt catalysts were prepared. The catalysts were composed of W6Co7 intermetallic compounds and tungsten-dispersed cobalt. With the increase of the W/Co ratio in the precursors, the content of W6Co7 was increased. Because the W6Co7 intermetallic compound can enable the chirality specified growth of SWNTs, the selectivity of the resulting SWNTs is improved at a higher W/Co ratio. At a W/Co ratio of 6 : 4 and under optimized chemical vapor deposition conditions, we realized the direct growth of semiconducting SWNTs with the purity of ~96%, in which ~62% are (14, 4) tubes. Using salts as precursors to prepare tungsten-cobalt bimetallic catalysts is flexible and convenient. This offers an efficient pathway for the large-scale preparation of chirality enriched semiconducting SWNTs. PMID- 29594290 TI - An aryl-fused redox-active tetrathiafulvalene with enhanced mixed-valence and radical-cation dimer stabilities. AB - Molecular recognition of stable organic radicals is a relatively novel, but important structural binding motif in supramolecular chemistry. Here, we report on a redox-switchable veratrole-fused tetrathiafulvalene derivative VTTF which is ideally suited for this purpose and for the incorporation into stimuli-responsive systems. As revealed by electrochemistry, UV/Vis measurements, X-ray analysis, and electrocrystallisation, VTTF can be reversibly oxidised to the corresponding radical-cation or dication which shows optoelectronic and structural propterties similar to tetrathiafulvalene and tetrakis(methylthio)tetrathiafulvalene. However, theoretical calculations, variable temperature EPR, and NIR spectroscopy indicate that the dispersion-driven binding in the mixed-valence dimer (VTTF2)+ (KMV = 69 M-1 in CH2Cl2) and the radical-cation dimer (VTTF+)2 (KRC = 38 M-1 in CH3CN) is significantly enhanced by the additional veratrole pi-surface in comparison to pristine tetrathiafulvalene.

AB - We report an 'oxidation state' regulating method for the synthesis of anisotropic wurtzite CoO nanocrytals (NCs) with various shapes, including ultrathin nanosheets and a core-antenna structure for the first time. We show that the decomposition process of precursors was altered by their oxidation, which played a significant role in the unconventional growth. PMID- 29594294 TI - A first principle comparative study of the ionic diffusivity in LiAlO2 and NaAlO2 polymorphs for solid-state battery applications. AB - Lithium aluminates are attracting increasing attention as battery materials. They are typically used for the coating of electrodes. The diffusive properties of the equilibrium tetragonal phase (gamma) are well understood from both an experimental and a theoretical perspective, and the major diffusive mechanism is recognised to be vacancy hopping between neighbouring sites. Investigations of this type are however not reported for other, high-pressure LiAlO2 phases. Moreover, the ionic diffusivity of the Na-based aluminates, manifesting a similar polymorphism to LiAlO2, has never been studied using atomistic techniques. In this work, we address these points, by presenting a comparative density functional theory-based study of these materials, describing the structural properties of the various phases, and evaluating the activation energies for single vacancy hops. While LiAlO2 exhibits a poor ionic conductivity due to a significant degree of covalency of the Al-O bonding, orthorhombic beta-NaAlO2 exhibits a significantly lower diffusion barrier. This feature cannot be explained only in terms of the larger equilibrium volume, as the same trend is not observed for the high-pressure trigonal alpha-LiAlO2 and alpha-NaAlO2. We utilise here various electronic-structure tools to verify the lower degree of covalency of the Na-O bonds. The electron localisation function, in particular, is shown to be intrinsically correlated to the diffusion pathways of Li and Na ions, and its variation along the path is a qualitative measure of ionic conductivity. PMID- 29594295 TI - Structural and dielectric properties of cobaltacarborane composite polybenzimidazole membranes as solid polymer electrolytes at high temperature. AB - The conductivity of a series of composite membranes, based on polybenzimidazole (PBI) containing the metallacarborane salt M[Co(C2B9H11)2], M[COSANE] and tetraphenylborate, M[B(C6H5)4], M[TPB] both anions having the same number of atoms and the same negative charge, has been investigated. Different cations (M = H+, Li+ and Na+) have been studied and the composite membranes have been characterized by water uptake, swelling ratios, ATR FT-IR, thermogravimetric analysis and electrochemical impedance spectroscopy to explore the dielectric response and ion dynamics in composite membranes. Our results show that conductivity increases with increasing temperature and it is higher for H+ than for Li+ and Na+ for all temperatures under study. The mobility of Li+ is greater in [COSANE]- than in [TPB]- composite PBI@membranes while for Na+ it is the opposite. The temperature dependence of the conductivity of the composite was followed by a typical Arrhenius behaviour with two different regions: (1) between 20 and 100 degrees C, and (2) between 100 and 150 degrees C. Using the analysis of electrode polarization (EP) based on the Thrukhan theory we have calculated the ionic diffusion coefficients and the density of carriers. From the double logarithmic plot of the imaginary part of the conductivity (sigma'') versus frequency in the entire range of temperatures studied we have determined for each sample at each temperature, the frequency values of the onset (fON) and full development of electrode polarization (fMAX), respectively, which permit us to calculate static permittivity.

AB - The ene cyclization has evolved to become an indispensable tool for the synthesis of various ring size heterocyclic compounds. In the past and recent years, many exciting reports have demonstrated the broad scope and synthetic utility of ene cyclization and the versatility of oxonium ion, iminium ion and thionium ion intermediates. Moreover, the ease of regio- and stereoselectivity of ene cyclization has led to the development of new types of heterocyclic compounds. This article aims at reviewing the utilities of ene cyclization reactions for the synthesis of various ring sizes of oxygen, nitrogen and sulfur heterocycles. It also covers some applications in natural product synthesis. The mechanism of the reactions is discussed wherever necessary. The review article covers the time period from 1986 to 2017.

AB - Cobalt-doped MoS2 nanosheets were prepared via a facile hydrothermal method, exhibiting bifunctional activities of hydrogen and oxygen evolution reactions in both acidic and alkaline media. Cobalt doping not only improves the conductivity, decreasing the hydrogen adsorption free energy of MoS2 for HER, but also contributes catalytic active sites for OER.

AB - A chiral organic base catalyst with halogen-bonding-donor functionality has been developed. This quinidine-derived acid/base catalyst smoothly promoted the asymmetric Mannich reaction of malononitrile and various N-Boc imines with up to 98% ee. The cooperative interaction with both substrates was responsible for the high activity that allowed a reduction of the catalyst amount to 0.5 mol%. PMID- 29594300 TI - Theory of diffusioosmosis in a charged nanochannel. AB - We probe the diffusioosmotic transport in a charged nanofluidic channel in the presence of an applied tangential salt concentration gradient. Ionic salt gradient driven diffusioosmosis or ionic diffusioosmosis (IDO) is characterized by the generation of an induced tangential electric field and a diffusioosmotic velocity (DOSV) that is a combination of an electroosmotic velocity (EOSV) triggered by this electric field and a chemiosmotic velocity (COSV) triggered by an induced tangential pressure gradient. We explain that unlike the existing theories on IDO, it is more appropriate to apply the zero net current conditions (formulation F2) and not more restrictive zero net local flux conditions (formulation F1) particularly for the case where one considers a nanochannel connected to two reservoirs. We pinpoint limitations in the existing literature in correctly predicting the diffusioosmotic behavior even for the case where formulation F1 is used. We address these limitations and establish that (a) the induced electric field is an interplay of the differences in ionic diffusivity, the EDL-induced imbalance in ion concentrations, and the advection effects, (b) formulation F1 may overpredict or underpredict the electric field and the EOSV leading to an overprediction/underprediction of the DOSV and (c) formulation F2 demonstrates remarkable fluid physics of localized backflows owing to a dominant local influence of the COSV, which is missed by formulation F1. We anticipate that our theory will provide the first rigorous understanding of nanofluidic IDO with applications in multiple areas of low Reynolds number transport such as biofluidics, microfluidic separation, and colloidal transport. PMID- 29594301 TI - Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids. AB - We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir based NPs using Ni(COD)2 and [Ir(COD)OCH3]2 in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIm.NTf2). The prepared NPs had either core shell-like or alloy-like structures with the presence of Ni,Ir-oxides, depending on the synthetic approach. X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS), high-resolution transmission electron microscopy (HRTEM), X ray photoelectron spectroscopy (XPS), extended X-ray absorption fine structure (EXAFS), and magnetic measurements are combined to describe the influence of nanostructure on the magnetic behavior of these nanosystems. The present findings reveal that the alloy NPs display a disordered magnetic state, similar to a spin glass (SG)-like system (Tf = 7.2 K). Core-shell NPs are formed by a magnetically blocked/unblocked core with a magnetically disordered shell as deduced from the two magnetic responses peaking at TB = 75 K and Tf = 5.8 K. Coupling at the core shell interface leads to an exchange bias revealed at low temperature as horizontal shifts in the hysteresis loops of 0.12 kOe at 2 K. PMID- 29594303 TI - A theoretical study on mixtures of amino acid-based ionic liquids. AB - Ionic liquid mixtures containing amino acid anions are studied at the microscopic level using molecular dynamics simulations. The analysis of relevant features such as intermolecular forces (hydrogen bonding), molecular level arrangements, and properties of solvation spheres, allowed inferring the structuring of the studied mixtures. The effects of mixture compositions and the number of cations and anions were analysed in detail. The reported results showed even distribution of anions around cations. The absence of microheterogeneities and low deviations from ideality are due to the similar mechanism of interaction between the considered anions and cations. Likewise, the most relevant features are produced by the development of hydrogen bonding between the amino acid carboxylate group and hydrogen bond donor sites in the cations.

Ir1 with a two-photon action cross-section of 40 GM in the NIR region has been developed for targeting intracellular histidine. Two-photon micrographs showed that Ir1 could rapidly and selectively light up the nucleus in both fixed and live cells and is capable of displaying nuclear histidine distribution in ultra-detail using a super resolution (SR) technique under stimulated emission depletion (STED) microscopy. PMID- 29594304 TI - Stacking sequences of black phosphorous allotropes and the corresponding few layer phosphorenes. AB - Possible bulk black phosphorus (BP) allotropes are constructed based on single layer BP with various stacking sequences. Our stacking algorithm shows that there are eight possible allotropes with two stacking layers in their unit cells possessing relatively high symmetries, and six of them are retained after structural relaxation using a van der Waals correction of optB88-vdW. The AF, AG, and AH bulk structures are presented for the first time. The structural relationship of these configurations has been explained via an interlayer slipping process. The total energy of the AF allotrope is closest to the most stable bulk BP structure (AB stacking) among all explored 2-layer stacked bulk structures. The calculated band structure of the AF allotrope using HSE06 shows a direct band gap of 0.48 eV with anisotropic electronic structures. We also presented six possible BP allotropes with three stacking layers in their unit cells. The newly reported AAF and ABC stacked structures show semiconducting and metallic features, respectively. After the bulk structures were explored, we further built the corresponding few-layer phosphorene structures and investigated their electronic properties. The results show that all the few-layer phosphorenes show semiconducting features. The AE, AAE, and AEA phosphorenes have indirect band gaps while the other explored phosphorenes possess direct band gaps located at the Gamma point.

AB - Luminescence properties of SrS:Ce pellets sintered at 1700 degrees C were investigated under high pressure. Two different Ce3+-related emissions were confirmed to appear in the blue-green and red parts of the spectrum and were shown to shift significantly and linearly to longer wavelengths with increasing pressure. Changes in decay times of both emissions were also thoroughly analyzed. The results confirmed that Ce3+ ion pairing/clustering occurring due to their enhanced mobility at high temperatures is responsible for the appearance of the recently reported red Ce3+ emission in sintered SrS:Ce pellets. PMID- 29594306 TI - Label-free and sensitive detection of Ochratoxin A based on dsDNA-templated copper nanoparticles and exonuclease-catalyzed target recycling amplification. AB - Ochratoxin A (OTA) is one of the most toxic mycotoxins and exists in various food commodities. Herein, a sensitive fluorescence method was developed for OTA detection which combines the advantages of label-free dsDNA-templated copper nanoparticles (CuNPs), high selectivity of OTA aptamer and high efficiency of exonuclease-catalyzed target recycling amplification. OTA aptamer was hybridized with its complementary DNA (cDNA), and the obtained dsDNA acted as the template for fluorescent CuNPs. In the presence of its target (OTA), the aptamer prefers to form an OTA-aptamer complex in lieu of an aptamer-DNA duplex, which results in the dissociation of the aptamer-DNA duplex. The released cDNA and aptamer could be digested into mononucleotides by the RecJf exonuclease (single-stranded DNA specific exonuclease), and the target was liberated and could participate in the next reaction cycle. The above process resulted in the degradation of a large amount of template dsDNA, which prevented the synthesis of CuNPs, thus resulting in low fluorescence of the system. Based on this strategy, a label-free and sensitive detection of OTA was developed with a low detection limit of 5 ng mL-1 (S/N = 3). Our strategy was further validated and evaluated successfully by assaying OTA in real samples. The proposed assay has great potential as an OTA quantification method for use in the food safety field.

PMID- 29594308 TI - Sunlight-charged heterojunction TiO2 and WO3 particle-embedded inorganic membranes for night-time environmental applications. AB - A metal oxide-heterojunction photocatalyst is developed to harvest sunlight, store the energy in electrons, and apply the stored energy in water treatment. Light-absorbing nanoparticular and nanotubular TiO2 are hybridized with electron storing WO3 at different weight ratios of TiO2 to WO3 (e.g., TW25 represents a composite of 25 wt% TiO2 and 75 wt% WO3). The ability of the TW composite to utilize the stored electrons is examined for the reduction of hexavalent chromium (Cr(vi)). In the photoelectrochemical (PEC) tests, irradiation using simulated sunlight (AM 1.5, 100 mW cm-2) leads to a rapid shift in the open-circuit potential (OCP) of the TW electrodes to the negative potential region (photocharging process). The termination of irradiation causes a gradual shift of the OCP to the positive potential region over 20 h (discharging process). Spiked Cr(vi) added to the solution with pre-photocharged TW electrodes is efficiently removed; the kinetics of this process depends on the TW composition (25, 50, or 75 wt%), TiO2 morphology (particular or tubular), initial Cr(vi) concentration (0.125 or 0.25 ppm), and whether the conditions are aerated or non-aerated. Based on this knowledge, TW composite-embedded inorganic membranes are synthesized and charged using sunlight. For Cr(vi) removal, single-pass and continuous circulation filtration systems are employed. The fraction of Cr(vi) removed from the circulation system is ~30% in 4 h, which is 1.5 times that removed using the single-pass filtration system (~20%). An X-ray photoelectron spectroscopy analysis of the TW membranes used for Cr(vi) removal reveals that Cr is not sorbed in the membrane. The W(vi) in WO3 is partially reduced to W(6-x)+ upon photocharging and is oxidized during the reduction of Cr(vi), leading to the co existence of W6+ and W(6-x)+.

AB - An iridium complex featuring a metalated lutidine-derived CNP ligand reacts with KOtBu to yield a dimeric species with the two metal centers bound to the opposite ligands through the CHN arms. Furthermore, reaction with H2 in the presence of KOtBu of the same iridium derivative results in the hydrogenation of the CH[double bond, length as m-dash]CH- imidazolylidene moiety of the complex. NMR spectroscopy monitoring of the latter reaction supports the initial formation of a dihydride iridium complex containing an imidazolylidene ligand fragment that is hydrogenated after prolonged reaction time. PMID- 29594310 TI - The carbon chain-selective adenylation enzyme TamA: the missing link between fatty acid and pyrrole natural product biosynthesis. AB - The marine bacterium Pseudoalteromonas tunicata produces the bipyrrole antibiotic tambjamine YP1. This natural product is built from common amino acid and fatty acid building blocks in a biosynthetic pathway that is encoded in the tam operon which contains 19 genes. The exact role that each of these Tam proteins plays in tambjamine biosynthesis is not known. Here, we provide evidence that TamA initiates the synthesis and controls the chain length of the essential tambjamine fatty amine tail. Sequence analysis suggests the unusual TamA is comprised of an N-terminal adenylation (ANL) domain fused to a C-terminal acyl carrier protein (ACP). Mass spectrometry analysis of recombinant TamA revealed the surprising presence of bound C11 and C12 acyl-adenylate intermediates. Acylation of the ACP domain was observed upon attachment of the phosphopantetheine (4'-PP) arm to the ACP. We also show that TamA can transfer fatty acids ranging in chain length from C6-C13 to an isolated ACP domain. Thus TamA bridges the gap between primary and secondary metabolism by linking fatty acid and pyrrole biosynthetic pathways.

AB - Purpose: The aims of the study were to compare the Cognitive Self-Report Questionnaire (CSRQ; Spina, Ruff, & Mahncke, 2006) Hearing and Cognitive subscale ratings among older adults with and without probable mild cognitive impairment (MCI) and to examine whether self-report, as measured by the CSRQ, is associated with objective measures of hearing, auditory processing, and cognition. Method: Data analyses included 97 older adults of ages 61-91 years. Participants completed the CSRQ self-report measure as well as a battery of objective measures, including pure-tone audiometry, degraded speech understanding, temporal processing, and memory. Results: Older adults with probable MCI rated their cognitive abilities more poorly than those without MCI (p = .002), but ratings of hearing and auditory abilities did not differ between the two groups (p = .912). Age and CSRQ Hearing subscale ratings explained a significant proportion of variance in objective measures of hearing and degraded speech understanding (R2 = .39, p < .001). Age, sex, mental status, and CSRQ Cognition subscale ratings explained a significant proportion of variance in objective memory performance (R2 = .55, p < .001). Conclusions: Taken together, these results suggest that the CSRQ is an appropriate self-report measure of hearing, cognition, and some aspects of auditory processing for older adults with and without probable MCI. PMID- 29594312 TI - The Effect of Partner Reauditorization on Undergraduates' Attitudes Toward a Peer Who Communicates With Augmentative and Alternative Communication. AB - Purpose: This study compared college students' attitudes toward a peer who used a nonelectronic augmentative and alternative communication (AAC) system with and without a partner reauditorization strategy and also examined the effect of reauditorization on reported (a) ease of understanding the peer who used AAC, (b) willingness to engage in interactions with the peer who used AAC, and (c) preferences regarding AAC systems. Method: Sixty-four participants completed surveys after viewing each of 2 counterbalanced conditions involving a video of a peer who communicated using AAC. Mean survey ratings were compared between conditions. Results: Participants reported (a) more positive attitudes toward, (b) a greater ease in understanding, and (c) an increased willingness to interact with the peer who used nonelectronic AAC with partner reauditorization. Participants indicated that reauditorization contributed positively to the observed conversation. Reported preferences for nonelectronic AAC systems did not vary as a function of reauditorization, and most participants reported a preference for an electronic speech-generating device when compared with a nonelectronic system. Conclusion: Partner reauditorization may play a role in improving attitudes that individuals hold about peers who use nonelectronic AAC and may contribute to ease of understanding the aided message and increased likelihood of peer interactions. PMID- 29594313 TI - Automated Language Environment Analysis: A Research Synthesis. AB - Purpose: The Language Environment Analysis (LENA(r)) represents a breakthrough in automatic speech detection because it makes one's language environment, what adults and children actually hear and say, efficiently measurable. The purpose of this article was to examine (a) current dimensions of LENA research, (b) LENA's sensitivity to differences in populations and language environments, and (c) what has been achieved in closing the Word Gap. Method: From electronic and human searches, 83 peer-reviewed articles using LENA were identified, and 53 met inclusionary criteria and were included in a systematic literature review. Each article reported results of 1 study. Results: Originally developed to make natural language research more efficient and feasible, systematic review identified a broad landscape of relevant LENA findings focused primarily on the environments and communications of young children but also older adults and teachers. LENA's automated speech indicators (adult input, adult-child interaction, and child production) and the audio environment were shown to meet high validity standards, including accuracy, sensitivity to individual differences, and differences in populations, settings, contexts within settings, speakers, and languages. Researchers' own analyses of LENA audio recordings have extended our knowledge of microlevel processes in adult-child interaction. To date, intervention research using LENA has consisted of small pilot experiments, primarily on the effects of brief parent education plus quantitative linguistic feedback to parents. Conclusion: Evidence showed that automated analysis has made a place in the repertoire of language research and practice. Implications, limitations, and future research are discussed.

AB - We established a luciferase reporter assay system, the Multi-ImmunoTox Assay (MITA), which can evaluate the effects of chemicals on the promoter activities of four cytokines: IL-2, IFN-gamma, IL-1beta, and IL-8. We previously reported that MITA correctly reflected the change in mRNA of human whole-blood cells treated with dexamethasone, cyclosporine, FK506, or several other immunosuppressive drugs. In this study, we combined MITA with the IL-8 Luc assay to detect skin sensitization chemicals (OECD 442E) (modified MITA: mMITA) and established a data set of 60 chemicals examined by mMITA. Using the mMITA results, chemicals can be classified based on the lowest observed effect level (LOEL) of chemicals in suppressing or augmenting the promoter activities of the four cytokines. Moreover, we demonstrated that K-means clustering and hierarchical clustering of the 60 chemicals based on the LOEL for their effects on IL-2 and IL-8 promoter activities and the judgment by the IL-8 Luc assay resulted in the same 6-cluster solution: cluster 1 with preferential suppression of IL-8, cluster 2 with suppression of IL-2 and a positive IL-8 Luc assay result, cluster 3 with suppression of both IL-2 and IL-8, cluster 4 with no effects on IL-2 or IL-8 and a negative IL-8 Luc assay result, cluster 5 with suppression of both IL-2 and IL 8 and a negative IL-8 Luc assay result, and cluster 6 with preferential suppression of IL-8. These data suggest that mMITA is a promising novel high throughput approach for detecting unrecognized immunological effects of chemicals and for profiling their immunotoxic effects. PMID- 29594316 TI - An integrated approach to elucidate signaling pathways of dioscin-induced apoptosis, energy metabolism and differentiation in acute myeloid leukemia. AB - Although the therapeutics have improved the rates of remission and cure of acute myelogenous leukemia (AML) in recent decades, there is still an unmet medical need for AML therapies because disease relapses are a major obstacle in patients who become refractory to salvage therapy. The development of therapeutic agents promoting both cytotoxicity and cell differentiation may provide opportunities to improve the clinical outcome. Dioscin-induced apoptosis in leukemic cells was identified through death receptor-mediated extrinsic apoptosis pathway. The formation of Bak and tBid, and loss of mitochondrial membrane potential were induced by dioscin suggesting the activation of intrinsic apoptotsis pathway. A functional analysis of transcription factors using transcription factor-DNA interaction array and IPA analysis demonstrated that dioscin induced a profound increase of protein expression of CCAAT/enhancer-binding protein alpha (C/EBPalpha), a critical factor for myeloid differentiation. Two-dimensional gel electrophoresis assay confirmed the increase of C/EBPalpha expression. Dioscin induced differentiation was substantiated by an increase of CD11b protein expression and the induction of differentiation toward myelomonocytic/granulocytic lineages using hematoxylin and eosin staining. Moreover, both glycolysis and gluconeogenesis pathways after two-dimensional gel electrophoresis assay and IPA network enrichment analysis were proposed to dioscin action. In conclusion, the data suggest that dioscin exerts its antileukemic effect through the upregulation of both death ligands and death receptors and a crosstalk activation of mitochondrial apoptosis pathway with the collaboration of tBid and Bak formation. In addition, proteomics approach reveals an altered metabolic signature of dioscin-treated cells and the induction of differentiation of promyelocytes to granulocytes and monocytes in which the C/EBPalpha plays a key role. PMID- 29594318 TI - Adrenal crisis after first infusion of zoledronic acid: a case report. AB - Patients with Addison's disease are at greater risk of having reduced bone mineral density and hip fractures and are thus more likely to receive a bisphosphonate than their peers. Potent intravenous bisphosphonates could provoke an acute phase reaction. An 80-year-old female with Addison's disease received her first infusion of zoledronic acid for osteoporosis at our outpatient clinic around noon. Despite doubling her usual afternoon hydrocortisone dose, she became feverish, nauseous, extremely weak, and hypotensive over the night. When transported to the nearest general hospital the next morning, the patient was found to have signs of hypovolemic shock and she was admitted to the ICU. Crystalloid infusion, followed by dobutamine and norepinephrine drip, had no effect. Only after her European emergency card for glucocorticoid cover was found, adrenal crisis was recognized, and she was immediately given an intravenous bolus of hydrocortisone followed by continuous hydrocortisone infusion. The patient rapidly improved and was transferred to a regular ward the next day, where hydrocortisone dose was gradually tapered. Our experience might suggest that patients with Addison's disease should probably start their treatment with zoledronic acid in a hospital setting. Their usual oral dose of hydrocortisone should be doubled or even tripled. Careful monitoring of these patients seems to be warranted, and intravenous hydrocortisone should be given if any symptoms or signs of the imminent adrenal crisis are noted.

AB - BACKGROUND: Acute kidney injury (AKI) has both high mortality and morbidity. OBJECTIVES: To prevent the occurrence of AKI, current recommendations from the renal section of the DGIIN (Deutschen Gesellschaft fur Internistische Intensivmedizin und Notfallmedizin), OGIAIN (Osterreichischen Gesellschaft fur Internistische und Allgemeine Intensivmedizin und Notfallmedizin) and DIVI (Deutschen Interdisziplinaren Vereinigung fur Intensiv- und Notfallmedizin) are stated. MATERIALS AND METHODS: The recommendations stated in this paper are based on the current Kidney Disease Improving Global Outcomes (KDIGO) guidelines, the published statements of the "Working Group on Prevention, AKI section of the European Society of Intensive Care Medicine" and the expert knowledge and clinical experience of the authors. RESULTS: Currently there are no approved clinically effective drugs for the prevention of AKI. Therefore the mainstay of prevention is the optimization of renal perfusion by improving the mean arterial pressure (>65 mm Hg, higher target may be considered in hypertensive patients). This can be done by vasopressors, preferably norepinephrine and achieving or maintaining euvolemia. Hyperhydration that can lead to AKI itself should be avoided. In patients with maintained diuresis this can be done by diuretics that are per se no preventive drug for AKI. Radiocontrast enhanced imaging should not be withheld from patients at risk for AKI; if indicated, however, the contrast media should be limited to the smallest possible volume. PMID- 29594319 TI - Outcome of rolled fortified vaginal flap operation on female patients with intrinsic sphincteric deficiency: 2-year follow-up. AB - INTRODUCTION AND HYPOTHESIS: We evaluate the 2-year outcome of the rolled fortified vaginal flap (RFVF) operation for the treatment of stress urinary incontinence (SUI) due to intrinsic sphincteric deficiency (ISD). METHODS: A prospective study of 20 women suffering from SUI due to ISD was conducted. All patients were subjected to history-taking, clinical examination, cough stress test, and urodynamics. Symptom severity and quality of life (QoL) were assessed using the Arabic version of the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI-SF). All studied women were followed up for 24 months to detect success rate, any postoperative complications, and reveal changes in the quality of life. RESULTS: Mean age was 53 +/- 8 years. Preoperative Valsalva leak point pressure was 50.1 +/- 11.3 cmH2O. After a follow-up period of 24 months, only 2 patients (10%) showed mild stress incontinence with mean VLPP 80+/- 3 cm H2O. Postoperative mean maximum flow rate (Q-max) and mean Pdet-Qmax showed no significant difference from the preoperative results (P = 0.115 and 0.187 respectively). The quality of life domain of the ICIQ-UI-SF decreased significantly from 73.5 +/- 12.1% (preoperatively) to 2.6 +/- 8.1% (after a 1-year follow-up), P < 0.001 and then showed a slight increase to 4.5 +/- 10.6 at 24 months' follow-up. CONCLUSION: The RFVF operation has a success rate of 90% after a 24-month follow-up. It significantly improved the quality of life of women with SUI due to ISD.

AB - BACKGROUND: The involvement of the cervical spine in rheumatoid arthritis (RA) continues to be of clinical importance even in this age of biologics. Pathophysiological changes begin with an isolated atlantoaxial subluxation and may progress to a complex craniocervical and subaxial instability. The onset of cervical myelopathy can occur at any time and leads to a deterioration of the prognosis for the patient. THERAPY: Treatment of the rheumatoid cervical spine should be aimed at improvement of the symptoms and prevention of further progress of the disease. In the case of instability, this is only possible by surgical treatment. The increasing usage of biological agents has led to a change in the clinical picture of the cervical involvement in RA patients. There are fewer patients presenting with isolated atlantoaxial instability. In contrast, the number of patients with complex craniocervical and/or subaxial instabilities is increasing. Complex cervical instabilities may require a longer fusion from the occiput to the upper thoracic spine. Modern operative techniques make this complex surgery also possible in severely disabled patients with a high comorbidity.

PMID- 29594323 TI - Beach handball is safer than indoor team handball: injury rates during the 2017 European Beach Handball Championships. AB - PURPOSE: Beach handball is a relatively new type of sports, which was derived from team handball. Medical issues such as frequency and severity of injury are yet unknown. The purpose of this study was to investigate the injury pattern and injury rates of this new type of sports. METHODS: This study investigated the injury incidence of 30 national teams (10 senior and 20 u-17 teams, 16 men's and 14 women's teams) participating in the 2017 European Beach Handball Championships. Reports on injuries sustained during the senior and u-17 youth tournaments were provided by the medical staff of each team. Injury incidence was differentiated between age and sex, and between the five field positions (goalkeeper, wing, central defender, pivot, and specialist). RESULTS: During the tournaments, 87 injuries were recorded yielding an overall injury incidence of 286.1 per 1000 match hours. Time-loss due to injury was 49.3 per 1000 match hours. Senior players had a higher overall injury incidence with 395.3 injuries than u-17 players with 205.7 injuries per 1000 h match hours (p < 0.01). Comparison of the injury incidence between the two sexes showed 330.23 injuries per 1000 h handball exposure for male players and 234.9 injuries for female players (n.s.). The most frequent injury type was sprains (21 injuries, 24.1%) followed by contusions (19 injuries, 21.8%) and skin abrasions with (15 injuries, 17.2%). Central defenders and specialists had the highest injury incidence. Thighs, ankles, as well as foot and toes (altogether 12 injuries, all 13.8%) were the three most frequently injured anatomic sites. CONCLUSIONS: Beach handball seems to have a lower incidence of time-loss injuries than that reported for indoor team handball. This study is an important basis for developing injury prevention strategies in this sports that should focus on thighs, ankles, feet and toes. Further research into this new type of sports is essential to identify risk factors and to develop adequate injury prevention measures. LEVEL OF EVIDENCE: II. PMID- 29594324 TI - Under-corrected knees do not fail more than aligned knees at 8 years in fixed severe valgus total knee replacement. AB - PURPOSES: A fixed severe valgus knee is a surgical challenge. A safe post operative Hip-Knee-Ankle angle (HKA) range of 180 degrees +/- 4 was recommended, but recent studies mentioned equal results from outliers of this range. Nevertheless, no distinction was made between varus and valgus knees, as well as over-corrected or under-corrected knees. Did post-operative nonaligned total knee replacements (TKR) from fixed severe valgus knees behave differently from the properly aligned population? Did over-corrected knees behave differently from under-corrected knees? METHODS: Through a multi-center retrospective cohort study, we provided 557 knees of at least 10 degrees of minimal pre-operative valgus; in this population 75 presented a post-operative Hip-Knee-Ankle angle (HKA) outside of the 180 degrees +/- 4 range; 23 of them had at least 5 degrees of varus; 52 of them had at least 5 degrees of valgus. Median pre-operative HKA of the entire cohort was 194 degrees (range 190-198). Median follow-up was 8 years (range 5-11); Knee Society Score (KSS) results, HKA, Femoral and Tibial Mechanical Angles (FMA, TMA) and complication rates were obtained. The outlier group (HKA <= 175 or >= 185) was compared to the control group (HKA 180 +/- 4); over-corrected (HKA <= 175) and under-corrected (HKA >= 185) sub-groups were individually tested against the control group. RESULTS: The outlier group had a lower Final Knee Score than the aligned group (p = 0.023). In the over-corrected sub-group, median post-operative FMA was 88 degrees (SD 4 degrees ) and median TMA was 87 degrees (SD 4 degrees ). The complication rate was higher (p = 0.019). Knee (p = 0.018), Function (p = 0.034) and Final Knee Scores (p = 0.03) were statistically lower than in the control group. In the under-corrected sub group, mean post-operative FMA was 93 degrees (SD 2 degrees ) and mean TMA was 91 degrees (SD 2 degrees ). The complication rate was lower (p = 0.019) and there was no difference with the control group concerning KSS. CONCLUSIONS: In case of pre-operative fixed severe valgus knee, one should avoid over-correcting HKA angle and especially the TMA. Over-correction of a severe preoperative valgus in a post-operative varus was prejudicial for TKA survival. Keeping a severe valgus knee in low valgus to avoid using a more constrained implant and/or ligament releases will not decrease the 5-10 year implant survival and functional scores.

AB - The nucleoside reverse transcriptase inhibitor zidovudine (AZT), used in HIV infection treatment, induces mitochondrial DNA (mtDNA) depletion. A cause-effect relationship between mtDNA status alterations and autophagy has been reported. Both events are common in several liver diseases, including hepatocellular carcinoma. Here, we have studied autophagy activation in rat liver with mtDNA depletion induced by AZT administration in drinking water for 35 days. AZT at a concentration of 1 mg/ml, but not 0.5 mg/ml in the drinking water, decreased mtDNA levels in rat liver and extrahepatic tissues. In liver, mtDNA-encoded cytochrome c oxidase 1 protein levels were decreased. Although serum biomarkers of liver and kidney toxicity remained unaltered, beta-hydroxybutyrate levels were increased in liver of AZT-treated rats. Moreover, autophagy was dysregulated at two levels: (i) decreased induction signalling of this process as indicated by increases in autophagy inhibitors activity (AKT/mTOR), and absence of changes (Beclin-1, Atg5, Atg7) or decreases (AMPK/ULK1) in the expression/activity of pro autophagy proteins; and (ii) reduced autophagosome degradation as indicated by decreases in the lysosome abundance (LAMP2 marker) and the transcription factor TFEB controlling lysosome biogenesis. This resulted in increased autophagosome abundance (LC3-II marker) and accumulation of the protein selectively degraded by autophagy p62, and the transcription factor Nrf2 in liver of AZT-treated rats. Nrf2 was activated as indicated by the up-regulation of antioxidant target genes Nqo1 and Hmox-1. In conclusion, rat liver with AZT-induced mtDNA depletion presented dysregulations in autophagosome formation and degradation balance, which results in accumulation of these structures in parenchymal liver cells, favouring hepatocarcinogenesis. PMID- 29594325 TI - Can inadequate acromiohumeral distance improvement and poor posterior remnant tissue be the predictive factors of re-tear? Preliminary outcomes of arthroscopic superior capsular reconstruction. AB - PURPOSE: The factors affecting the anatomical and functional outcomes of arthroscopic superior capsular reconstruction (ASCR) were investigated in this study. Continuity between the posterior remnant tissue and graft, as well as medial-to-lateral anatomical graft continuity, might play a vital role in shoulder stability and functional recovery, which could be correlated with postoperative factors such as the acromiohumeral distance (AHD). METHODS: Thirty two patients (36 shoulders) who underwent ASCR were included. The follow-up period was 24.8 +/- 6.9 months. The relationship between graft continuity and preoperative, intraoperative, and postoperative factors that could affect the clinical and radiological outcomes of ASCR were investigated. RESULTS: The American Shoulder and Elbow Surgeons score increased from 50.3 +/- 9.1 points preoperatively to 84.0 +/- 5.0 points postoperatively (p < 0.01), and the Constant score increased from 56.3 +/- 9.0 to 82.8 +/- 5.6 points (p = 0.02). Re tearing occurred in 13 patients during the postoperative follow-up period. The re tear rate was relatively high (36.1%). The gap between the immediate postoperative and preoperative AHDs was 1.6 +/- 2.2 mm in the re-tear (+) group and 3.8 +/- 2.8 mm in the re-tear (-) group (p = 0.02). The integrity of the posterior remnant tissue had a statistically significant and different re-tear rate (p < 0.01). CONCLUSION: Care should be taken in patients with inadequate AHD improvement and poor posterior remnant tissue immediately postoperatively, because the possibility of re-tearing is high. Therefore, better results can be predicted when considering these factors at the time of surgery. LEVEL OF EVIDENCE: IV. PMID- 29594327 TI - Coffee consumption, metabolic syndrome and clinical severity of psoriasis: good or bad stuff? AB - Despite the wide consumption of coffee, its anti-inflammatory effect on clinical severity of psoriasis is still debatable. The aim of this study was to evaluate the association between the coffee consumption and clinical severity of psoriasis in a sample of patients stratified according to the presence of the metabolic syndrome (MetS) and smoking. This cross-sectional case-control observational study was conducted on 221 treatment-naive psoriatic patients. Lifestyle habits, anthropometric measures, clinical and biochemical evaluations were obtained. Clinical severity of psoriasis was assessed by Psoriasis Area and Severity Index (PASI) score. Data on energy caloric intake and coffee consumption were collected using a 7-day food diary record. The coffee consumption was analyzed as coffee intake (consumers and non-consumers) and daily servings (range 0-4 servings/day). Coffee consumers have a lower PASI score vs non-consumers (p < 0.001). The lowest PASI score and MetS prevalence were found in patients consuming 3 cups of coffee/day (p < 0.001), which was also the most common daily serving (34.8%), whereas the highest PASI score was found among those drinking >= 4 cups/day. Grouping the case patients according to smoking and MetS, the best odds of PASI score was observed in those drinking 3 cups of coffee per day and no smokers, after adjusting for total energy intake (OR 74.8; p < 0.001). As a novel finding, we reported a negative association between coffee intake, MetS prevalence and clinical severity of psoriasis. The evaluation of the anti-inflammatory effect of coffee on clinical severity of psoriasis, whose metabolic risk increases along with its clinical severity, could be of great importance from a public health perspective.

AB - OBJECTIVE: The Matthiass test serves to identify postural insufficiencies by evaluating the sagittal posture but this subjective assessment may be responsible for different reports on the prevalence of postural insufficiencies in children. Previously, rasterstereography was used to objectify this clinical test. Until now, the coupling of the Matthiass test with rasterstereography has not yet been applied to children and the reliability is unknown; therefore, the objective of our study was to provide interday and interrater reliability of rasterstereographic measurements during dynamic (modified Matthiass test) and static trials (only interday) in healthy children. METHODS: Trunk inclination, kyphotic, and lordotic angles were measured using rasterstereography during static and dynamic trials (modified Matthiass test: 90 degrees shoulder flexion, hand-held load, 5% of body weight). Intraclass correlation coefficients (ICC) were calculated using a two-way mixed model (absolute agreement, average measure). RESULTS: In this study 21 healthy children were assessed (age range 10 12 years). Dynamic rasterstereographic measurements showed fair to good interday and interrater reliability (ICC 0.46-0.70) and static measurements good to excellent interday reliability (ICC 0.63-0.91). CONCLUSION: Dynamic rasterstereography during the modified Matthiass test furnishes reliable data serving to objectify spinal changes of healthy children and detect postural insufficiencies. Additional efforts are needed to investigate how the early detection of postural insufficiencies can help to prevent back pain in children, adolescents and adults.

PMID- 29594330 TI - Can the world's favorite fruit, tomato, provide an effective biosynthetic chassis for high-value metabolites? AB - Tomato has a relatively short growth cycle (fruit ready to pick within 65-85 days from planting) and a relatively high yield (the average for globe tomatoes is 3-9 kg fruit per plant rising to as much as 40 kg fruit per plant). Tomatoes also produce large amounts of important primary and secondary metabolites which can serve as intermediates or substrates for producing valuable new compounds. As a model crop, tomato already has a broad range of tools and resources available for biotechnological applications, either increased nutrients for health-promoting biofortified foods or as a production system for high-value compounds. These advantages make tomato an excellent chassis for the production of important metabolites. We summarize recent achievements in metabolic engineering of tomato and suggest new candidate metabolites which could be targets for metabolic engineering. We offer a scheme for how to establish tomato as a chassis for industrial-scale production of high-value metabolites. PMID- 29594331 TI - Extracellular vesicle-mediated MHC cross-dressing in immune homeostasis, transplantation, infectious diseases, and cancer. AB - Eukaryotic cells employ different types of extracellular vesicles (EVs) to exchange proteins, mRNAs, non-coding regulatory RNAs, carbohydrates, and lipids. Cells of the immune system, in particular antigen (Ag)-presenting cells (APCs), acquire major histocompatibility complex (MHC) class I and II molecules loaded with antigenic peptides from leukocytes and tissue parenchymal and stromal cells, through a mechanism known as MHC cross-dressing. Increasing evidence indicates that cross-dressing of APCs with pre-formed Ag-peptide/MHC complexes (pMHCs) is mediated via passage of clusters of EVs with characteristics of exosomes. A percentage of the transferred EVs remain attached to the acceptor APCs, with the appropriate orientation, at sufficient concentration within localized areas of the plasma membrane, and for sufficient time, so the preformed pMHCs carried by the EVs are presented without further processing, to cognate T cells. Although its biological relevance is not fully understood, numerous studies have demonstrated that MHC cross-dressing of APCs represents a pathway of Ag presentation of acquired pre-formed pMHCs to T cells-alternative to direct and cross-presentation-participate in immune homeostasis and T cell tolerance, cross regulate alloreactive T cells with different MHC restricted specificities, and is a mechanism of Ag spreading for autologous, allogeneic, microbial, tumor, or vaccine-delivered Ags. Here, we compare MHC cross-dressing with other mechanisms and terminologies used for pMHC transfer, including trogocytosis. We discuss the experimental evidence, mostly from in vitro and ex vivo studies, of the role of MHC cross-dressing of APCs via EVs in positive or negative regulation of T cell immunity in the steady state, transplantation, microbial diseases, and cancer.

AB - PURPOSE: Cancer stem cells (CSCs) are responsible for colorectal cancer (CRC) initiation, growth, and metastasis. Garlic-derived organosulfur compound diallyl trisulfide (DATS) possesses cancer suppressive properties. Wnt/beta-catenin signaling is a key target for CSCs inhibition. However, the interventional effect of DATS on colorectal CSCs has not been clarified. We aimed to illustrate the regulation of Wnt/beta-catenin in DATS-induced colorectal CSCs inhibition. METHODS: Serum-free medium culture was used to enrich colorectal CSCs. SW480 and DLD-1 sphere-forming cells were treated with different concentrations of DATS for 5 days; LiCl and beta-catenin plasmids were used to stimulate the activity of Wnt/beta-catenin pathway. The size and number of colonspheres were detected by tumorsphere formation assay; the expression of colorectal CSCs-related genes was detected by Western blotting and qRT-PCR; the capacities of colorectal CSCs proliferation and apoptosis were detected by Cell Counting Kit-8, Hoechst 33258 cell staining and flow cytometry, respectively. RESULTS: The levels of colorectal CSCs markers were elevated in the tumorspheres cells. DATS efficiently suppressed the activity of colorectal CSCs, as evidenced by reducing the size and number of colonspheres, decreasing the expression of colorectal CSCs markers, promoting apoptosis and inhibiting the proliferation of colorectal CSCs. Moreover, DATS suppressed the activity of Wnt/beta-catenin pathway, while upregulation of Wnt/beta-catenin diminished the inhibitory effect of DATS on colorectal CSCs. CONCLUSIONS: Wnt/beta-catenin pathway mediates DATS-induced colorectal CSCs suppression. These findings support the use of DATS for targeting colorectal CSCs. PMID- 29594333 TI - The effectiveness of the low-power laser and kinesiotaping in the treatment of carpal tunnel syndrome, a pilot study. AB - In mild and moderate cases of carpal tunnel syndrome (CTS), the conservative approach is suggested. The purpose of this study is to assess and compare the effect of low-power laser versus the combination of low-power laser and kinesiotaping on pain, muscle strength, functionality, and electrophysiologic parameters in the patients with CTS. The study was planned as single-blind, prospective, randomized control. 64 hands diagnosed with CTS were included in the study. The patients were randomly divided into three groups by closed envelope method. Low-power laser therapy was applied to Group 1 (21 hands), kinesiotaping and low-power laser therapy in group 2 (22 hands), sham laser therapy in Group 3 (21 hands). All patients were assessed by visual numeric pain scale (VNS), hand grip strength (HGS), finger pinch strength (FPS), the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ), before treatment, after treatment (3rd week), and after (12th week) 3 months the treatment with the same physician. Motor and sensory nerve conduction studies were performed with electroneuromyography (ENMG) before the treatment (0th week) and at the end of the 12th week. Comparison of the group 1 with the group 3 showed significantly better improvement in the former in VNS, BCTSQ at 3rd week and 12th week compared to 0th week, and in FPS and HGS at 3rd week. Comparison of the group 2 with the group 3 showed significantly better improvement in the former VNS, BCTSQ, FPS and HGS at 3rd and 12th week compared to 0th week. When Group 1 and Group 2 were compared there was no statistically significant difference in any parameters in the 3rd week, but there was a statistically significant difference in favor of group 2 in FPS and HGS parameters at the 12th week. We have found that the kinesiotaping method applied with low-power laser treatment does not provide any additional benefit to the low-power laser treatment in the short term, however, in the long term, the increase in the HGS and FPS has occurred. In conclusion, low-power laser and kinesiotaping method in the treatment of CTS may be an effective and reliable treatment option in clinical parameters.

AB - PURPOSE: The retromolar canal (RMC) and foramen (RMF) are anatomic variants in the retromolar area of the mandible. The purpose of this study was to clarify the relationship between the RMC and RMF and related complications, and to reveal how the RMC could impact the mandibular anatomy using cone-beam computed tomography (CBCT) and panoramic images (PAN). MATERIALS AND METHODS: CBCT and PAN images of 50 patients were retrospectively analyzed to investigate the morphology of the RMC and RMF, and their impact on impacted third molar surgery and orthognathic surgery. RESULTS: In PAN images, neither the RMC nor RMF was detected. In CBCT images, the RMCs were detected in 26% (13/50) of the patients. A double RMC was detected on one side of one patient. The diameter of the RMC ranged from 0.8 to 2.9 mm (mean; 1.5 +/- 0.6 mm), and the RMF ranged from 0.6 to 2.3 mm (mean; 1.1 +/- 0.5 mm). No patients experienced unexpected bleeding. Unilateral postoperative hypoesthesia of the buccal gingiva in the molar region was reported in 6.7% of patients with the RMC. CONCLUSIONS: Hypoesthesia of the buccal gingiva in the lower molar region may be the main complication when the RMC is damaged. PMID- 29594336 TI - A rare case of atypical thoracodorsal artery: a challenge for flap reconstruction. AB - The thoracodorsal artery mainly supplies the latissimus dorsi muscle. Anatomical details pertaining to the origin and distribution of thoracodorsal artery are important because the latissimus dorsi myocutaneous flap is one of the most reliable and versatile flaps used in reconstructive surgery. Atypical origin and course of the thoracodorsal artery is, therefore, a challenge for flap reconstruction surgeries. In the present case, we report multiple variations in the branching pattern of axillary artery. The thoracodorsal artery had an unusual origin from the second part of axillary artery. The trunk of thoracoacromial artery was absent. The thoracodorsal artery after its origin, descended downwards over the lateral pectoral region lying deep to pectoralis minor but superficial to teres major muscles. It terminated by supplying the latissimus dorsi muscle. Due to the presence of atypical thoracodorsal branch, the subscapular artery continued as the circumflex scapular artery. PMID- 29594337 TI - Therapeutic potential of GSK-J4, a histone demethylase KDM6B/JMJD3 inhibitor, for acute myeloid leukemia. AB - PURPOSE: Acute myeloid leukemia (AML) is a heterogeneous disease with poor outcomes. Despite increased evidence shows that dysregulation of histone modification contributes to AML, specific drugs targeting key histone modulators are not applied in the clinical treatment of AML. Here, we investigated whether targeting KDM6B, the demethylase of tri-methylated histone H3 lysine 27 (H3K27me3), has a therapeutic potential for AML. METHODS: A KDM6B-specific inhibitor, GSK-J4, was applied to treat the primary cells from AML patients and AML cell lines in vitro and in vivo. RNA-sequencing was performed to reveal the underlying mechanisms of inhibiting KDM6B for the treatment of AML. RESULTS: Here we observed that the mRNA expression of KDM6B was up-regulated in AML and positively correlated with poor survival. Treatment with GSK-J4 increased the global level of H3K27me3 and reduced the proliferation and colony-forming ability of primary AML cells and AML cell lines. GSK-J4 treatment significantly induced cell apoptosis and cell-cycle arrest in Kasumi-1 cells, and displayed a synergistic effect with cytosine arabinoside. Notably, injection of GSK-J4 attenuated the disease progression in a human AML xenograft mouse model in vivo. Treatment with GSK-J4 predominantly resulted in down-regulation of DNA replication and cell-cycle-related pathways, as well as abrogated the expression of critical cancer-promoting HOX genes. ChIP-qPCR validated an increased enrichment of H3K27me3 in the transcription start sites of these HOX genes. CONCLUSIONS: In summary, our findings suggest that targeting KDM6B with GSK-J4 has a therapeutic potential for the treatment of AML. PMID- 29594338 TI - Macro- and micromechanical remodelling in the fish atrium is associated with regulation of collagen 1 alpha 3 chain expression. AB - Numerous pathologies lead to remodelling of the mammalian ventricle, often associated with fibrosis. Recent work in fish has shown that fibrotic remodelling of the ventricle is 'reversible', changing seasonally as temperature-induced changes in blood viscosity alter haemodynamic load on the heart. The atrial response to varying haemodynamic load is less understood in mammals and completely unexplored in non-mammalian vertebrates. To investigate atrial remodelling, rainbow trout were chronically cooled (from 10 +/- 1 to 5 +/- 1 degrees C) and chronically warmed (from 10 +/- 1 to 18 +/- 1 degrees C) for a minimum of 8 weeks. We assessed the functional effects on compliance using ex vivo heart preparations and atomic force microscopy nano-indentation and found chronic cold increased passive stiffness of the whole atrium and micromechanical stiffness of tissue sections. We then performed histological, biochemical and molecular assays to probe the mechanisms underlying functional remodelling of the atrial tissue. We found cooling resulted in collagen deposition which was associated with an upregulation of collagen-promoting genes, including the fish specific collagen I alpha 3 chain, and a reduction in gelatinase activity of collagen-degrading matrix metalloproteinases (MMPs). Finally, we found that cooling reduced mRNA expression of cardiac growth factors and hypertrophic markers. Following long-term warming, there was an opposing response to that seen with cooling; however, these changes were more moderate. Our findings suggest that chronic cooling causes atrial dilation and increased myocardial stiffness in trout atria analogous to pathological states defined by changes in preload or afterload of the mammalian atria. The reversal of this phenotype following chronic warming is particularly interesting as it suggests that typically pathological features of mammalian atrial remodelling may oscillate seasonally in the fish, revealing a more dynamic and plastic atrial remodelling response. PMID- 29594339 TI - Obesogenic habits among children and their families in response to initiation of gluten-free diet. AB - : Initiation of a lifelong, gluten-free diet (GFD) in children with celiac disease (CD) influences the child's life in many ways. The aim of this study was to assess the influence of GFD on the child and his/her family's eating habits and lifestyle behaviors. To study this, we asked children and their parents completed the Family Eating and Activity Habits Questionnaire (FEAHQ) at the time of diagnosis of CD and at least 6 months after initiation of GFD and a questionnaires assessing symptoms related to CD and adherence to the GFD diet. We analyzed questionnaires from 40 children with CD and their families. There were 21 females, ranging in age from 4 to 15.7 years (median age 7.4 years+/-2.8 years). The control group comprised 15 healthy children. After initiation of GFD the family ate more junk food including snacks and candies (p = 0.05), with the significant change reported by children and fathers (p = 0.001 and 0.03 respectively). All family members in the control group had significantly less snacks. Parents and children reported a significant increase in obesogenic eating styles, such as eating from the cooking pot and eating while doing other activities (mothers, p = 0.001; fathers, 0.02; and children, 0.02 respectively). CONCLUSIONS: Our study shows that initiation of GFD in children with CD leads to changes in eating habits and staple food eating that may lead to a more obesogenic environment. Care givers, pediatricians, gastroenterologists, and dieticians alike should be aware of these implications and educate families towards a healthier lifestyle and diet beyond the GFD itself. What's Known: * Gluten-free diet has been shown to affect various psychosocial aspects of children with celiac disease. * Obesity and celiac are associated. What is New: * Initiation of gluten-free diet led to increased eating of junk food both in the patient and his/her family. * After initiation of GFD pro-obesogenic eating habits is increased. PMID- 29594340 TI - Work ability score of solvent-exposed workers. AB - PURPOSE: Occupational chronic solvent encephalopathy (CSE), characterized by neurocognitive dysfunction, often leads to early retirement. However, only the more severe cases are diagnosed with CSE, and little is known about the work ability of solvent-exposed workers in general. The aim was to study memory and concentration symptoms, work ability and the effect of both solvent-related and non-occupational factors on work ability, in an actively working solvent-exposed population. METHODS: A questionnaire on exposure and health was sent to 3640 workers in four solvent-exposed fields, i.e. painters and floor-layers, boat builders, printers, and metal workers. The total number of responses was 1730. We determined the work ability score (WAS), a single question item of the Work Ability Index, and studied solvent exposure, demographic factors, Euroquest memory and concentration symptoms, chronic diseases, and employment status using univariate and multivariate analyses. The findings were compared to those of a corresponding national blue-collar reference population (n = 221), and a small cohort of workers with CSE (n = 18). RESULTS: The proportion of workers with memory and concentration symptoms was significantly associated with solvent exposure. The WAS of solvent-exposed workers was lower than that of the national blue-collar reference group, and the difference was significant in the oldest age group (those aged over 60). Solvent-exposed worker's WAS were higher than those of workers diagnosed with CSE. The WAS were lowest among painters and floor layers, followed by metal workers and printers, and highest among boat builders. The strongest explanatory factors for poor work ability were the number of chronic diseases, age and employment status. Solvent exposure was a weak independent risk factor for reduced WAS, comparable to a level of high alcohol consumption. CONCLUSIONS: Even if memory and concentration symptoms were associated with higher solvent exposure, the effect of solvents on self experienced work ability was relatively weak. This in line with the improved occupational hygiene and reduced solvent exposure levels in industrialized countries, thus the effect may be stronger in high-level exposure environments. As a single question, WAS is easily included, applicable, and recommendable in occupational screening questionnaires. PMID- 29594341 TI - Anaerobic bacteria in wastewater treatment plant. AB - PURPOSE: The objective of this study was to assess exposure to anaerobic bacteria released into air from sewage and sludge at workplaces from a wastewater treatment plant (WWTP). METHODS: Samples of both sewage and sludge were collected at six sampling points and bioaerosol samples were additionally collected (with the use of a 6-stage Andersen impactor) at ten workplaces covering different stages of the technological process. Qualitative identification of all isolated strains was performed using the biochemical API 20A test. Additionally, the determination of Clostridium pathogens was carried out using 16S rRNA gene sequence analysis. RESULTS: The average concentration of anaerobic bacteria in the sewage samples was 5.49 * 104 CFU/mL (GSD = 85.4) and in sludge-1.42 * 106 CFU/g (GSD = 5.1). In turn, the average airborne bacterial concentration was at the level of 50 CFU/m3 (GSD = 5.83) and the highest bacterial contamination (4.06 * 103 CFU/m3) was found in winter at the bar screens. In total, 16 bacterial species were determined, from which the predominant strains belonged to Actinomyces, Bifidobacterium, Clostridium, Propionibacterium and Peptostreptococcus genera. The analysis revealed that mechanical treatment processes were responsible for a substantial emission of anaerobic bacteria into the air. In both the sewage and air samples, Clostridium perfringens pathogen was identified. CONCLUSIONS: Anaerobic bacteria were widely present both in the sewage and in the air at workplaces from the WWTP, especially when the technological process was performed in closed spaces. Anaerobic bacteria formed small aggregates with both wastewater droplets and dust particles of sewage sludge origin and as such may be responsible for adverse health outcomes in exposed workers. PMID- 29594342 TI - Defining microbial community composition and seasonal variation in a sewage treatment plant in India using a down-flow hanging sponge reactor. AB - The characteristics of the microbial community in a practical-scale down-flow hanging sponge (DHS) reactor, high in organic matter and sulfate ion concentration, and the seasonal variation of the microbial community composition were investigated. Microorganisms related to sulfur oxidation and reduction (2 27%), as well as Leucobacter (7.50%), were abundant in the reactor. Anaerobic bacteria (27-38% in the first layer) were also in abundance and were found to contribute to the removal of organic matter from the sewage in the reactor. By comparing the Simpson index, the abundance-based coverage estimator (ACE) index, and the species composition of the microbial community across seasons (summer/dry, summer/rainy, autumn/dry, and winter/dry), the microbial community was found to change in composition only during the winter season. In addition to the estimation of seasonal variation, the difference in the microbial community composition along the axes of the DHS reactor was investigated for the first time. Although the abundance of each bacterial species differed along both axes of the reactor, the change of the community composition in the reactor was found to be greater along the vertical axis than the horizontal axis of the DHS reactor. PMID- 29594343 TI - Heat and light stresses affect metabolite production in the fruit body of the medicinal mushroom Cordyceps militaris. AB - Cordyceps militaris is a highly valued edible and medicinal fungus due to its production of various metabolites, including adenosine, cordycepin, N6-(2 hydroxyethyl)-adenosine, and carotenoids. The contents of these metabolites are indicative of the quality of commercially available fruit body of this fungus. In this work, the effects of environmental abiotic factors, including heat and light stresses, on the fruit body growth and metabolite production in C. militaris were evaluated during the late growth stage. The optimal growth temperature of C. militaris was 20 degrees C. It was found that a heat stress of 25 degrees C for 5-20 days during the late growth stage significantly promoted cordycepin and carotenoid production without affecting the biological efficiency. Light stress at 6000 lx for 5-20 days during the late growth stage significantly promoted cordycepin production but decreased the carotenoid content. Both heat and light stresses promoted N6-(2-hydroxyethyl)-adenosine production. In addition, gene expression analysis showed that there were simultaneous increases in the expression of genes encoding a metal-dependent phosphohydrolase (CCM_04437) and ATP phosphoribosyltransferase (CCM_04438) that are involved in the cordycepin biosynthesis pathway, which was consistent with the accumulation of cordycepin during heat stress for 5-20 days. A positive weak correlation between the cordycepin and adenosine contents was observed with a Pearson correlation coefficient of 0.338 (P < 0.05). The results presented herein provide a new strategy for the production of a superior quality fruit body of C. militaris and contribute to further elucidation of the effects of abiotic stress on metabolite accumulation in fungi. PMID- 29594344 TI - A key residue for the substrate affinity enhancement of a thermophilic endo polygalacturonase revealed by computational design. AB - Protein engineering has been a research hotspot to improve the catalytic efficiency of industrially important enzymes. In the present study, a novel computational strategy was developed to in silico screen mutants with enhanced binding interaction between enzyme and substrate as well as catalytic efficiency. Through homology modeling and molecular dynamics (MD) simulation, four key residues related to substrate binding were identified in the endo polygalacturonase BiPG28A from Bispora sp. MEY-1. Further analyses of the conformation, hydrogen bond interactions, and binding free energy revealed that lysine at position 129 (subsite - 2) has the strongest affinity to substrate. Biochemical and calorimetry experiments confirmed the functional role of Lys129 in substrate binding through non-covalent interactions. The common role of Lys129 was also verified in another GH28 endo-polygalacturonase. Distinguished from other protein engineering strategies involving structure resolution and construction of certain enzymes, this computational strategy represents an insightful and efficient approach to develop a "designed" enzyme with significantly enhanced binding affinity and catalytic efficiency. PMID- 29594345 TI - Ubc7/Ube2g2 ortholog in Entamoeba histolytica: connection with the plasma membrane and phagocytosis. AB - Endoplasmic reticulum (ER)-associated degradation (ERAD) and unfolded protein response (UPR) pathways are important for quality and quantity control of membrane and secretory proteins. We have identified orthologs of ER-associated ubiquitin conjugating enzymes (E2s) Ubc6/Ube2j2 and Ubc7/Ube2g2, ubiquitin ligases (E3) Hrd1 and GP78/AMFR, and sensor of UPR, Ire1 in E. histolytica that show conservation of important features of these proteins. Biochemical characterization of the ortholog of ERAD E2, Ubc7/Ube2g2 (termed as EhUbc7), was carried out. This E2 was transcriptionally upregulated several folds upon induction of UPR with tunicamycin. Ire1 ortholog was also upregulated upon UPR induction suggesting a linked UPR and ERAD pathway in this organism. EhUbc7 showed enzymatic activity and, similar to its orthologs in higher eukaryotes, formed polyubiquitin chains in vitro and localized to both cytoplasm and membranes. However, unlike its ortholog in higher eukaryotes, it also showed localization to the plasma membrane along with calreticulin. Inactivation of EhUbc7 significantly inhibited erythrophagocytosis, suggesting a novel function that has not been reported before for this E2. No change in growth, motility, or cell-surface expression of Gal/GalNAC lectin was observed due to inactivation of EhUbc7. The protein was present in the phagocytic cups but not in the phagosomes. A significant decrease in the number of phagocytic cups in inactive EhUbc7 expressing cells was observed, suggesting altered kinetics of phagocytosis. These findings have implications for evolutionary and mechanistic understanding of connection between phagocytosis and ER-associated proteins. PMID- 29594346 TI - Bulk tank milk prevalence and production losses, spatial analysis, and predictive risk mapping of Ostertagia ostertagi infections in Mexican cattle herds. AB - This study investigated the prevalence, production losses, spatial clustering, and predictive risk mapping in different climate zones in five states of Mexico. The bulk tank milk samples obtained between January and April 2015 were analyzed for antibodies against Ostertagia ostertagi using the Svanovir ELISA. A total of 1204 farm owners or managers answered the questionnaire. The overall herd prevalence and mean optical density ratio (ODR) of parasite were 61.96% and 0.55, respectively. Overall, the production loss was approximately 0.542 kg of milk per parasited cow per day (mean ODR = 0.92, 142 farms, 11.79%). The spatial disease cluster analysis using SatScan software indicated that two high-risk clusters were observed. In the multivariable analysis, three models were tested for potential association with the ELISA results supported by climatic, environmental, and management factors. The final logistic regression model based on both climatic/environmental and management variables included the factors rainfall, elevation, land surface temperature (LST) day, and parasite control program that were significantly associated with an increased risk of infection. Geostatistical kriging was applied to generate a risk map for the presence of parasite in dairy cattle herds in Mexico. The results indicate that climatic and meteorological factors had a higher potential impact on the spatial distribution of O. ostertagi than the management factors. PMID- 29594347 TI - Nestedness in assemblages of helminth parasites of bats: a function of geography, environment, or host nestedness? AB - Nested subsets occur in ecological communities when species-poor communities are subsets of larger, species-rich communities. Understanding this pattern can help elucidate species colonization abilities, extinction risks, and general structuring of biological communities. Here, we evaluate nestedness in a poorly studied host-parasite system, bats and their helminths, across the Japanese archipelago and within its different bioclimatic regions. We hypothesized that (1) if helminth communities are nested across geographic sites at the level of the archipelago, then broad-scale processes, like colonization-extinction dynamics, mainly structure parasite assemblages; (2) if helminth communities are nested across geographic sites at the level of the bioclimatic region, then fine scale environmental variation plays a significant role in species nestedness; (3) if helminth community nestedness mirrors host species nestedness, then communities are nested because the habitats they occupy are nested; and (4) if nestedness does not occur or if it is not correlated with any geographical or host data, then passive sampling could be responsible for the patterns of parasite assemblage in our sample. We found that helminth communities were nested across host species throughout the archipelago but, when considering each bioclimatic region, helminths in only one region were significantly more nested than the null model. Helminth communities were also nested across sites within all four bioclimatic regions. These results suggest that helminths form nested subsets across the archipelago due to broad-scale processes that reflect the overall lineages of their mammalian hosts; however, at the regional scale, environmental processes related to nestedness of their habitats drive parasite community nestedness. PMID- 29594348 TI - Study of a seventeenth-century French artificial mummy: autopsical, native, and contrast-injected CT investigations. AB - BACKGROUND: A lead coffin was fortuitously discovered in a church called "Eglise des Toussaints" in Rennes (French Brittany). A collaborative taskforce investigated this extraordinary discovery. A multi-disciplinary team of experts from the National Institute for Preventive Archeological Research (INRAP) and Rangueil University Hospital of Toulouse was created, including anthropologists, archeologists, forensic pathologists, radiologists, and pathologists. The inscription on the lead coffin specified that the body belonged to "Messer Louys de Bruslon, Lord of Plessis," a nobleman who died on November 1, 1661. Multiple holes were visible in the lead coffin, and deterioration threatened the mummy. We opened the lead coffin and discovered an excellently preserved mummy, except for mostly skeletonized upper and lower limbs. The mummy was conserved in several layers of shrouds. Vegetal embalming material covered the head and filled the face, the thorax, and the abdomen. The embalmers had removed all thoracic and abdominal organs and conserved some pelvic organs (e.g., the bladder). METHODS: Multi-slice computed tomography (MSCT) scanner evaluated the mummy, at each step of our analysis. The excellent preservation of abdominal vascular axes led us to perform a CT angiography using Angiofil(r), an oily contrast agent developed for postmortem imaging, before an autopsy. RESULTS: Sub-diaphragmatic arteries, including the abdominal aorta and iliac arteries, were excellently preserved. The vascular contrast agent filled all arteries. The native CT, CT angiography, and autopsy did not detect any vascular lesion. CONCLUSION: Our study, based on rare archeological material, allowed a complete examination of an excellently preserved seventeenth-century mummy, using MSCT, angiography, and an autopsy. We did not detect any arterial lesion and proposed a comprehensive description of the embalmment process. PMID- 29594349 TI - Clinical performance of bulk-fill and conventional resin composite restorations in posterior teeth: a systematic review and meta-analysis. AB - OBJECTIVES: The purpose of this systematic review was to compare the clinical performance of bulk-fill resin composites with conventional resin composites used for direct restorations of posterior teeth. METHODS: This review followed the PRISMA statement. This review was registered at PROSPERO (registration number CRD42016053436). A search of the scientific literature was performed by two independent reviewers using the PubMed/MEDLINE, Embase, The Cochrane Library, and Web of Science databases from commencement until January 2018. The research question was "Do bulk-fill resin composites have a clinical performance comparable to conventional resin composites in posterior restorations?" Only studies evaluating class I and II direct restorations in permanent teeth with a follow-up period of at least 1 year were included. The RevMan 5 program was used for meta-analysis, calculating the relative risk (RR) and 95% confidence interval (CI) of the dichotomous outcome (restoration failure or success). RESULTS: Ten articles were selected, comprising 941 analyzed restorations. The mean follow-up period was 33.6 months (12-72 months). No statistically significant differences in the failure rate were observed between conventional and base/flowable bulk fill resin composites (p = 0.31; RR 1.49; 95% CI 0.69-3.25) or full body/sculptable bulk-fill resin composites (p = 0.12; RR 1.89; 95% CI 0.84-4.24). CONCLUSIONS: The present systematic review and meta-analysis indicate similar clinical performances of bulk-fill and conventional resin composites over a follow-up period of 12 to 72 months. CLINICAL SIGNIFICANCE: Based on the results of this study, the bulk-fill resin composites could be an alternative for direct restorations in posterior teeth. However, clinical trials of longer duration are required. PMID- 29594351 TI - Structure of the stigma and style of Callaeum psilophyllum (Malpighiaceae) and its relation with potential pollinators. AB - The family Malpighiaceae, particularly in the Neotropic, shows a similar floral morphology. Although floral attraction and rewards to pollinators are alike, stigmas and styles show more diversity. The stigmas were described covered with a thin and impermeable cuticle that needs to be ruptured by the mechanical action of the pollinators. However, this characteristic was only mentioned for a few species and the anatomy and ultrastructure of the stigmas were not explored. In this work, we analyze the morphology, anatomy, and ultrastructure of the stigma and style of Callaeum psilophyllum. Moreover, we identify the potential pollinators in order to evaluate how the disposition of the stigmas is related with their size and its role in the exposure of the receptive stigmatic surface. Our observations indicate that Centris flavifrons, C. fuscata, C. tarsata, and C. trigonoides are probably efficient pollinators of C. psilophyllum. The three stigmas are covered by a cuticle that remained intact in bagged flowers. The flowers exposed to visitors show the cuticle broken, more secretion in the intercellular spaces between sub-stigmatic cells and abundant electron-dense components inside vacuoles in stigmatic papillae. This indicates that the stigmas prepares in similar ways to receive pollen grains, but the pollinator action is required to break the cuticle, and once pollen tubes start growing, stigmatic and sub-stigmatic cells release more secretion by a granulocrine process. PMID- 29594350 TI - Transcriptional Regulators as Targets for Alcohol Pharmacotherapies. AB - Alcohol use disorder (AUD) is a chronic relapsing brain disease that currently afflicts over 15 million adults in the United States. Despite its prevalence, there are only three FDA-approved medications for AUD treatment, all of which show limited efficacy. Because of their ability to alter expression of a large number of genes, often with great cell-type and brain-region specificity, transcription factors and epigenetic modifiers serve as promising new targets for the development of AUD treatments aimed at the neural circuitry that underlies chronic alcohol abuse. In this chapter, we will discuss transcriptional regulators that can be targeted pharmacologically and have shown some efficacy in attenuating alcohol consumption when targeted. Specifically, the transcription factors cyclic AMP-responsive element binding protein (CREB), peroxisome proliferator-activated receptors (PPARs), nuclear factor kappa-light-chain enhancer of activated B cells (NF-kappaB), and glucocorticoid receptor (GR), as well as the epigenetic enzymes, the DNA methyltransferases (DNMTs) and histone deacetylases (HDACs), will be discussed. PMID- 29594352 TI - Analysis of membranous Ki-67 staining in breast cancer and surrounding breast epithelium. AB - Membranous Ki-67 staining with the MIB-1 antibody has been described in hyalinising trabecular adenomas of the thyroid and sclerosing haemangiomas of the lung. Its relatively rare occurrence in breast tumours has also been documented. The aim of the present study was to assess the rate of any membranous MIB-1 staining in breast specimens. The staining was performed at room temperature with 1:100 dilution of the antibody. One hundred four core needle biopsies and 41 operative specimens were analysed. Membranous staining was noted in 36/144 invasive carcinomas, 20/42 in situ carcinomas and 46/99 cases of peritumoural benign/normal breast epithelium. Most often, it presented as focal and partial polarised luminal membranous staining although complete circumferential staining also occurred, and membranous labelling was sometimes accompanied by cytoplasmic staining, too. In a few cases tested, greater dilution of the primary antibody did not abolish the membranous staining, which was absent with the SP6 monoclonal Ki-67 antibody. The membranous staining of invasive tumours showed no association with histological grade, lumen formation, oestrogen or progesterone receptor status or the Ki-67 nuclear labelling. In contrast, it was associated with a HER2 positive status, although it occurred in all molecular subtypes approached by immunohistochemistry. The background of this membranous staining remains elusive. It is unlikely to represent an artefact. At least partial sharing of an epitope of the nuclear Ki-67 protein with an unidentified membranous protein and some functional differences between membranous staining producing tumours and tumours lacking this pattern of staining may both contribute to some extent. PMID- 29594353 TI - Immune cell expression of TGFbeta1 in cancer with lymphoid stroma: dendritic cell and regulatory T cell contact. AB - Although cancer tissue generally shows limited immune responses, some cancers abound with lymphocytes, which generally show favorable prognosis. These cancers, despite their rarity, are important in analyzing immune responses in cancer tissue. Transforming growth factor beta1 (TFGbeta1) is a multifunctional cytokine, generally having an immunosuppressive function. The present study analyzes the in situ TGFbeta1 expression in 23 cases of lymphocyte-rich gastric carcinomas (Ly-rich GCs) using immunohistochemistry and in situ hybridization. Immunohistochemistry revealed that latency-associated peptide (LAP) of TGFbeta1 was localized in mainly immune cells in all cases, which was more abundant than in control GCs. Expression of LAP by cancer cells was only focal. In situ hybridization also confirmed abundant TGFbeta1 mRNA expression in the lymphoid stroma. Double immunofluorescent microscopy identified LAP+ cells as macrophages, dendritic cells, and part of T cells. Close cell-to-cell contact was observed between LAP+ dendritic-shaped cells and FoxP3+ regulatory T cells (Treg cells). Mature dendritic cells in Ly-rich GCs expressed LAP more frequently than those in the secondary lymphoid organs. Our data revealed abundant expression of TGFbeta1 in immune cells with contact to Treg cells in lymphoid stroma, which is consistent with the notion that TGFbeta1 is one of the immunosuppressive factors in cancer stroma. PMID- 29594355 TI - High-intensity intermittent "5-10-15" running reduces body fat, and increases lean body mass, bone mineral density, and performance in untrained subjects. AB - The present study examined the effect of intense intermittent running with 5 s sprints on body composition, fitness level, and performance in untrained subjects aged 36-53 years. For 7 weeks, the subjects carried out 3 days a week 5-10-15 training consisting of 3-9 blocks of 4 repetitions of 15, 10, and 5 s low-, moderate-, and high-speed running, respectively. Body fat mass was 4.3% lower (P < 0.01), and lean body mass and bone mineral density was 1.1 and 0.9% higher (P < 0.01), respectively, after compared to before the intervention period (INT). The plasma bone turnover markers osteocalcin increased (P < 0.01) by 147%, and procollagen-type I N propeptide and carboxy-terminal collagen crosslinks increased (P < 0.05) by 84 and 76%, respectively. Furthermore, the training improved performance in 1500 m (P < 0.001), 3 km (P < 0.001), Yo-Yo intermittent endurance test (P < 0.01), and incremental treadmill running (P < 0.001) by 8.1, 9.9, 17.2, and 23.9%, respectively. Furthermore, blood lactate after running at 85% of maximal aerobic speed was lower (P < 0.01) after compared to before the INT. Thus, 7 weeks of 5-10-15 training resulted in significant health beneficial changes and better performance in untrained subject. PMID- 29594354 TI - Detection of the Merkel cell polyomavirus in the neuroendocrine component of combined Merkel cell carcinoma. AB - Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma of the skin. The main etiological agent is Merkel cell polyomavirus (MCPyV), detected in 80% of cases. About 5% of cases, called combined MCC, feature an admixture of neuroendocrine and non-neuroendocrine tumor cells. Reports of the presence or absence of MCPyV in combined MCC are conflicting, most favoring the absence, which suggests that combined MCC might have independent etiological factors and pathogenesis. These discrepancies might occur with the use of different virus identification assays, with different sensitivities. In this study, we aimed to determine the viral status of combined MCC by a multimodal approach. We histologically reviewed 128 cases of MCC and sub-classified them as "combined" or "conventional." Both groups were compared by clinical data (age, sex, site, American Joint Committee on Cancer [AJCC] stage, immunosuppression, risk of recurrence, and death during follow-up) and immunochemical features (cytokeratin 20 and 7, thyroid transcription factor 1 [TTF1], p53, large T antigen [CM2B4], CD8 infiltrates). After a first calibration step with 12 conventional MCCs and 12 cutaneous squamous cell carcinomas as controls, all eight cases of combined MCC were investigated for MCPyV viral status by combining two independent molecular procedures. Furthermore, on multiplex genotyping assay, the samples were examined for the presence of other polyoma- and papillomaviruses. Combined MCC differed from conventional MCC in earlier AJCC stage, increased risk of recurrence and death, decreased CD8 infiltrates, more frequent TTF1 positivity (5/8), abnormal p53 expression (8/8), and frequent lack of large T antigen expression (7/8). With the molecular procedure, half of the combined MCC cases were positive for MCPyV in the neuroendocrine component. Beta papillomaviruses were detected in 5/8 combined MCC cases and 9/12 conventional MCC cases. In conclusion, the detection of MCPyV DNA in half of the combined MCC cases suggests similar routes of carcinogenesis for combined and conventional MCC. PMID- 29594356 TI - Multifunctional theranostic applications of biocompatible green-synthesized colloidal nanoparticles. AB - Phytochemicals offer immense promise for sustainable development and production of nanotechnology-enabled products. In the present study, Olax nana Wall. ex Benth. (family: Olacaceae) aqueous extract was used as an effective stabilizing agent to produce biogenic silver (ON-AgNPs) and gold nanoparticles (ON-AuNPs), which were investigated for biocompatibility and prospective biomedical applications (antibacterial, anticancer, antileishmanial, enzyme inhibition, antinociceptive, and anti-inflammatory activities). Various characterization techniques (XRD, FTIR, SEM, TEM, DLS, EDX, and SAED) revealed efficient biosynthesis of ON-AgNPs (26 nm) and ON-AuNPs (47 nm). In the toxicological assessment, ON-AgNPs and ON-AuNPs were found biocompatible towards human RBCs and macrophages (IC50 > 200 MUg/mL). In a concentration range of 62.5-2000 MUg/mL, a strong antibacterial effect was produced by ON-AgNPs against Staphylococcus epidermidis (MIC = 7.14 MUg/mL) and Escherichia coli (8.25 MUg/mL), while ON AuNPs was only active against Staphylococcus aureus (9.14 MUg/mL). At a concentration of 3.9-500 MUg/mL, a dose-dependant inhibition of HepG2 cancer cells was produced by ON-AgNPs (IC50 = 14.93 MUg/mL) and ON-AuNPs (2.97 MUg/mL). Both ON-AgNPs and ON-AuNPs were found active against Leishmania tropica (KMH23) promastigotes (IC50 = 12.56 and 21.52 MUg/mL) and amastigotes (17.44 and 42.20 MUg/mL), respectively, after exposure to a concentration range of 1-200 MUg/mL for 72 h. Preferential enzyme inhibition against urease and carbonic anhydrase II were noted for ON-AgNPs (39.23 and 8.89%) and ON-AuNPs (31.34 and 6.34%), respectively; however, these were found inactive against xanthine oxidase at 0.2 mg/mL. In the in vivo antinociceptive (acetic acid-induced abdominal constrictions) and anti-inflammatory (carrageenan-induced paw edema) activities, ON-AgNPs and ON-AuNPs at doses of 40 and 80 mg/kg, significantly attenuated the tonic nociception (P < 0.001) and ameliorated the carrageenan-induced inflammation (P < 0.01, P < 0.001). The results of in vitro and in vivo activities indicated that the biogenic nanoparticles can be used as valuable theranostic agents for further exploration of diverse biomedical applications. PMID- 29594357 TI - Insights into microbial communities mediating the bioremediation of hydrocarbon contaminated soil from an Alpine former military site. AB - The study of microbial communities involved in soil bioremediation is important to identify the specific microbial characteristics that determine improved decontamination rates. Here, we characterized bacterial, archaeal, and fungal communities in terms of (i) abundance (using quantitative PCR) and (ii) taxonomic diversity and structure (using Illumina amplicon sequencing) during the bioremediation of long-term hydrocarbon-contaminated soil from an Alpine former military site during 15 weeks comparing biostimulation (inorganic NPK fertilization) vs. natural attenuation and considering the effect of temperature (10 vs. 20 degrees C). Although a considerable amount of total petroleum hydrocarbon (TPH) loss could be attributed to natural attenuation, significantly higher TPH removal rates were obtained with NPK fertilization and at increased temperature, which were related to the stimulation of the activities of indigenous soil microorganisms. Changing structures of bacterial and fungal communities significantly explained shifts in TPH contents in both natural attenuation and biostimulation treatments at 10 and 20 degrees C. However, archaeal communities, in general, and changing abundances and diversities in bacterial and fungal communities did not play a decisive role on the effectiveness of soil bioremediation. Gammaproteobacteria and Bacteroidia classes, within bacterial community, and undescribed/novel groups, within fungal community, proved to be actively involved in TPH removal in natural attenuation and biostimulation at both temperatures.

AB - L-Valine is one of the three branched-chain amino acids (valine, leucine, and isoleucine) essential for animal health and important in metabolism; therefore, it is widely added in the products of food, medicine, and feed. L-Valine is predominantly produced through microbial fermentation, and the production efficiency largely depends on the quality of microorganisms. In recent years, continuing efforts have been made in revealing the mechanisms and regulation of L valine biosynthesis in Corynebacterium glutamicum, the most utilitarian bacterium for amino acid production. Metabolic engineering based on the metabolic biosynthesis and regulation of L-valine provides an effective alternative to the traditional breeding for strain development. Industrially competitive L-valine producing C. glutamicum strains have been constructed by genetically defined metabolic engineering. This article reviews the global metabolic and regulatory networks responsible for L-valine biosynthesis, the molecular mechanisms of regulation, and the strategies employed in C. glutamicum strain engineering. PMID- 29594359 TI - [Vascular surgical training concept for military surgeons in Germany]. AB - BACKGROUND: Due to the increasing threat of terrorist attacks and assassinations even in Europe, the interest in management of severe vascular injuries, which, with an increased incidence of 10% are to be expected with such penetrating wounds, is also growing; however, with increasing subspecialization in surgery there is a threat that the know-how in vascular surgery will become lost among non-vascular surgical specialists. Therefore, the Germany military established an educational program, the so-called DUOplus concept, to ensure that future military surgeons acquire and retain the experience and skills to fulfill the demanding role of a deployed surgeon. OBJECTIVE: The DUOplus concept of the German Medical Forces is introduced with a special focus on vascular surgery training. RESULTS: All trainee German military surgeons attain a second specialization alongside general surgery. This residency includes several courses in various surgical specialties as well as a 12-month rotation in a vascular surgery department. The core elements of vascular trauma training are two practical courses on life-like models. In these courses, which were developed especially for the needs of non-vascular surgeons in hands-on training, open surgical techniques and damage control measures including resuscitative endovascular balloon occlusion of the aorta (REBOA) are taught on suitable models and intensively practiced. CONCLUSION: All surgeons potentially confronted with traumatic and iatrogenic vascular injuries should have some basic competence in the management of vascular trauma. Especially the courses in vascular surgery for non-vascular surgeons offer such a skill set for every surgeon. Next to the German military surgeons, the courses are attended more and more by civilian and military surgeons from different surgical specialties and nationalities. PMID- 29594360 TI - A phase II, multicenter, single-arm trial of eribulin as first- or second-line chemotherapy for HER2-negative advanced or metastatic breast cancer: evaluation of efficacy, safety, and patient-reported outcomes. AB - PURPOSE: Although eribulin is a suitable option for early-line treatment of metastatic breast cancer (MBC), data on first- or second-line use of eribulin for human epidermal growth factor receptor 2 (HER2)-negative MBC are still limited. Therefore, we conducted a phase II trial to investigate the efficacy and safety of eribulin for first- or second-line chemotherapy for HER2-negative MBC. MATERIALS AND METHODS: We performed a phase II, open-label, single-arm, multicenter study in Japan. Eligible patients were women with histologically confirmed HER2-negative MBC without chemotherapy or only one chemotherapy line for MBC. The primary endpoint was the overall response rate (ORR) and the secondary endpoints included the clinical benefit rate (ORR + stable disease for 6 months; CBR), progression-free survival (PFS), overall survival (OS), duration of response (DOR), safety, and health-related quality of life (HRQoL). RESULTS: A total of 35 patients with HER2-negative MBC were enrolled between March 2013 and February 2017 (data cut-off July 31, 2017). The ORR was 37.1% (95% CI 21.1 53.2%). The CBR was 54.3% (95% CI 37.8-70.8%). The median PFS was 6.2 months (95% CI 2.7-9.4 months) and median OS was 21.4 months (95% CI 11.5-32.9 months). Common grade 3/4 adverse events were neutropenia (42.9%) but febrile neutropenia (2.9%). Although the majority of non-hematological adverse events were mild in severity, one patient died of pneumonitis. In HRQoL analysis, eribulin appeared to maintain HRQoL of many patients. CONCLUSIONS: Eribulin as first- or second line chemotherapy is effective and has manageable toxicity for patients with HER2 negative MBC. PMID- 29594361 TI - MircroRNA-139 sensitizes ovarian cancer cell to cisplatin-based chemotherapy through regulation of ATP7A/B. AB - PURPOSE: Ovarian cancer remains a most malignant female cancer nowadays. The acquisition of chemoresistance to common-used cisplatin-based chemotherapy results in a decreased overall patient survival. The present study is aimed to investigate the role and mechanism by which miR-139/ ATPases7A/B axis modulates the chemoresistance of ovarian cancer to cisplatin-based chemotherapy. METHODS: The expression of miR-139 in cisplatin-sensitive (n = 23) and cisplatin-resistant (n = 14) ovarian cancer tissues and cell lines (CAOV-3 and SNU119) was determined using real-time PCR assays; its effect on ovarian cancer cell chemoresistance to different concentrations of cisplatin was then assessed by measuring the cell viability using MTT assays. Next, miR-139 binding to the 3'UTR of ATP7A/B was confirmed using luciferase reporter gene assays. Finally, the combined effect of miR-139 and ATP7A/B on the chemoresistance of ovarian cancer cell was assessed. RESULTS: miR-139 expression was down-regulated in cisplatin-resistant ovarian cancer tissues (**P < 0.01) and reduced by cisplatin treatment in ovarian cell lines (*P < 0.05, **P < 0.01); miR-139 could enhance cisplatin-induced suppression on ovarian cancer cell viability, shown as reduced lC50 values; ATP7A and ATP7B protein levesincreased approximately 2 ~ fold-changein cisplatin resistant cell lines. MiR-139 directly bound to the 3'UTR of ATP7A/B, respectively; miR-139 inhibition increased lC50 values whereas ATP7A/B knockdown reduced lC50 values of CAOV-3 and SNU119 cell lines under cisplatin treatment; the effect of miR-139 inhibition could be partially attenuated by ATP7A/B knockdown. CONCLUSIONS: MiR-139/ATP7A/B axis can be a reliable biomarker for ovarian cancer diagnosis, and may affect the chemoresistance of ovarian cancer to cisplatin-based chemotherapy; rescuing miR-139 expression thus to inhibit ATP7A/B might contribute to dealing with the chemoresistance of ovarian cancer. PMID- 29594362 TI - Single-institution experience with gemcitabine-cisplatin combination therapy as a second-line treatment for patients with unresectable biliary tract cancer after failure of gemcitabine-S-1 combination therapy: a prospective feasibility study. AB - BACKGROUND: NCCN and Japanese clinical guidelines for the treatment of biliary tract cancer (BTC) addressed gemcitabine-cisplatin combination (GC) as first-line chemotherapy for patients with advanced BTC ineligible for surgery in 2013. However, gemcitabine-S1 combination therapy (GS) has been widely used as first line treatment in Japan because Japanese social insurance coverage of S-1 for BTC was approved prior to that of cisplatin. AIM: To elucidate the efficacy and tolerability of GC as second-line chemotherapy for patients with unresectable BTC after failure of GS. PATIENTS AND METHODS: Between September 2008 and August 2011, patients with unresectable BTC who provided informed consent and received GC comprising gemcitabine at 1000 mg/m2 and cisplatin at 20 mg/m2 given on days 1 and 8 in a 3-week cycle after failure of GS were included in the present study. Clinical data from these patients were collected prospectively. Primary endpoints were overall survival and time to progression (TTP). Secondary endpoints were response and tolerability. RESULTS: Twenty-seven patients were analyzed. Median survival time (MST) and TTP from the beginning of second-line treatment were 6.5 and 3.3 months, respectively, whereas MST from the commencement of first-line therapy was 12.06 months. One patient showed partial response, 16 had stable disease and 10 experienced disease progression. As a result, disease control rate was 63.0%. In total, 119 courses (median, 4; range, 1-15) were administered. Discontinuation of GC due to drug toxicities was not observed. CONCLUSION: Although some issues remain to be clarified, mainly due to the small sample size, this single-institution experience with GC as second-line treatment after failure of GS showed acceptable outcomes and good tolerability. PMID- 29594363 TI - Electrochemical immunosensor for the breast cancer marker CA 15-3 based on the catalytic activity of a CuS/reduced graphene oxide nanocomposite towards the electrooxidation of catechol. AB - The authors report on an electrochemical immunosensor for the tumor marker carbohydrate antigen 15-3 (CA15-3). It is based on the use of a composite consisting of reduced graphene oxide (RGO) and copper sulfide (CuS) that was placed on a screen-printed graphite electrode. The electrode shows excellent activity towards the oxidation of catechol acting as an electrochemical probe, best at a working potential of 0.16 V. The electrode was modified with antibody against CA15-3. Once the analyte (CA15-3) binds to the surface of the electrode, the response to catechol is reduced. The assay has a linear response in the 1.0 150 U mL-1 CA15-3 concentration range, with a 0.3 U mL-1 lower detection limit and a sensitivity of 1.88 MUA MUM-1 cm-2. The immunosensor also shows good reproducibility (2.7%), stability (95% of the initial values after storing for four weeks). The method was successfully applied to the determination of CA15-3 in serum samples, and results were found to compare well to those obtained by an ELISA. Conceivably, this nanocomposite based detection scheme has a wider scope and may be applied to numerous other immunoassays. Graphical abstract A label free electrochemical immunosensor based on copper sulfides/graphene nanocomposites was developed for enzyme-free determination of CA15-3 biomarker. This immunosensor can be utilized as a tool to detect of CA15-3 in real samples. PMID- 29594364 TI - Recombinant rabies virus expressing interleukin-6 enhances the immune response in mouse brain. AB - Rabies, which is caused by the rabies virus (RABV), is an ancient zoonosis that has a high mortality rate. Previous studies have indicated that recombinant RABV expressing canine interleukin-6 (rHEP-CaIL6), induced more virus-neutralizing antibodies than parental RABV in mice following intramuscular immunization. To investigate the immune response induced in the CNS by rHEP-CaIL6 after intranasal or intracranial administration in mice, the permeability of the blood-brain barrier (BBB), the infiltration of CD3 T cells, and innate immune response related effector molecules in the CNS were examined. It was observed that infection of rHEP-CaIL6 led to enhanced BBB permeability following intranasal infection. More CD3 T cells infiltrated into the central nervous system (CNS) in mice infected with rHEP-CaIL6 than in those infected with the HEP-Flury strain. Furthermore, rHEP-CaIL6 induced an increased expression of innate immune response related effector molecules, compared with the parental HEP-Flury strain, within the CNS. Taken together, these findings suggest that rHEP-CaIL6 induced stronger immune responses in mice brains, which is more beneficial for virus clearance. These results may also partly illustrate the role of IL6 in RABV infection. PMID- 29594365 TI - Microbead-based simultaneous fluorometric detection of three nut allergens. AB - A microbead-based method is developed for the detection of three nut allergens that can occur in food. The bead array constitutes of a suspension of spectrally distinct fluorescent polystyrene microbeads and has been applied for the simultaneous detection of three main and serious allergens (hazelnut, peanut and walnut). The method is based on the simultaneous identification of specific DNA sequences after PCR. The PCR products are biotinylated and hybridized to nut specific oligonucleotide probes attached to the microbeads. The hybrids are finally detected by a streptavidin-phycoerythrin conjugate and flow cytometric analysis. As low as 0.01% content of the three nuts in processed food (cookies) can be detected by this method. Graphical abstract Schematic of a method for simultaneous fluorometric detection of three nut allergens in processed food (cookies) based on the use of fluorescent microbeads and flow cytometric analysis.

AB - Single phase metastable alpha-AgVO3 microrods with high crystallinity, tetragonal rod-like microstructure, uniform particle size distribution, and good dispersion were synthesized by direct coprecipitation at room temperature. They are shown to be viable peroxidase mimics that catalyze the oxidation of 3,3',5,5' tetramethylbenzidine in the presence of H2O2. Kinetic analysis indicated typical Michaelis-Menten catalytic behavior. The findings were used to design a colorimetric assay for H2O2, best measured at 652 nm. The method has a linear response in the 60 to 200 MUM H2O2 concentration range, with a 2 MUM detection limit. Benefitting from the chemical stability of the microrods, the method is well reproducible. It also is easily performed and highly specific. Graphic abstract Single phase metastable alpha-AgVO3 microrods with high crystallinity, tetragonal rod-like microstructure, uniform particle size distribution, and good dispersion can efficiently catalyze the oxidation reaction of peroxidase substrate 3,3',5,5'-tetramethylbenzidine (TMB) in the presence of H2O2 to produce a blue color change. PMID- 29594367 TI - A SERS-based multiple immuno-nanoprobe for ultrasensitive detection of neomycin and quinolone antibiotics via a lateral flow assay. AB - The authors describe an ultrasensitive method for simultaneous detection of neomycin (NEO) and quinolones antibiotics (QNS). It is based on the use of (a) two immuno-nanoprobes (a probe for NEO and a probe for QNS), (b) surface-enhanced Raman scattering (SERS) detection, and (c), a portable lateral flow assay (LFA). The two probes consist of gold nanoparticles (AuNPs) conjugated to the Raman active molecule 4-aminothiophenol (PATP), and to monoclonal antibody against NEO (NEO mAb) or against NOR (NOR mAb). Quantitative detection of NEO and QNS was realized via SERS of the PATP-coated AuNPs captured in the test line of a LFA. Under optimized condition, the visual limits of LFA are 10 ng.mL-1 for NEO and 200 ng.mL-1 for NOR, and with LODs down to 0.37 pg.mL-1 and 0.55 pg.mL-1 by using SERS. The NEO test line is not interfered by the NEO analogues gentamycin, streptomycin and tobramycin, but the NOR test line suffers from different degrees of cross-reactivity (CR) to 12 common other QNS, the CRs ranging from 1.5% to 136%. The recoveries of NEO and NOR from spiked milk samples ranged between 86% and 121%, with relative standard deviations (RSD) from 3% to 6%. The method is highly sensitive, accurate and effective. It may be applied to simultaneous detection of NEO and 8 QNS, including NOR, enoxacin, ciprofloxacin, ofloxacin, fleroxacin, marbofloxacin, enrofloxacin, and pefloxacin. Graphical abstract Schematic of a lateral flow assay (LFA) based on an indirect competitive model. By using two test lines, the LFA can detect the neomycin and quinolones antibiotics simultaneously. Based on the surface-enhanced Raman scattering (SERS), the LFA shows high sensitivity to antibiotics with low limit of detection. PMID- 29594368 TI - Efficacy of individualized social competence training for children with oppositional defiant disorders/conduct disorders: a randomized controlled trial with an active control group. AB - Patient-focused cognitive-behavioral therapy in children with aggressive behavior, which uses group-based social skills training, has resulted in significant reductions in behavioral problems, with effect sizes in the small-to medium range. However, effects of individually delivered treatments and effects on aggressive behavior and comorbid conditions rated from different perspectives, child functional impairment, child quality of life, parent-child relationship, and parental psychopathology have rarely been assessed. In a randomized controlled trial, 91 boys aged 6-12 years with a diagnosis of oppositional defiant disorder/conduct disorder and peer-related aggression were randomized to receive individually delivered social competence training (Treatment Program for Children with Aggressive Behavior, THAV) or to an active control involving group play that included techniques to activate resources and the opportunity to train prosocial interactions in groups (PLAY). Outcome measures were rated by parents, teachers, or clinicians. Mostly moderate treatment effects for THAV compared to PLAY were found in parent ratings and/or clinician ratings on aggressive behavior, comorbid symptoms, psychosocial impairment, quality of life, parental stress, and negative expressed emotions. In teacher ratings, significant effects were found for ADHD symptoms and prosocial behavior only. THAV is a specifically effective intervention for boys aged 6-12 years with oppositional defiant disorder/conduct disorder and peer-related aggressive behavior as rated by parents and clinicians. PMID- 29594369 TI - Maternal adverse childhood experiences and antepartum risks: the moderating role of social support. AB - The aims of the current study were to examine the association between maternal adverse childhood experiences (ACEs) and antepartum health risks, and to investigate whether social support moderated this association. It was hypothesized that ACEs would be associated with antepartum health risks; however, social support in the prenatal period would buffer mothers from the deleterious consequences of ACEs. Data from 1994 women (mean age = 31 years) and their infants were collected from a longitudinal cohort recruited in health care offices in Alberta, Canada. Pregnant women completed questionnaires related to ACEs prior to the age of 18 and prenatal social support, and a health care professional assessed the mother's antepartum health risk. ACEs included physical, emotional, and sexual abuse, exposure to domestic violence, as well as exposure to household dysfunction such as parental substance use, mental illness, or incarceration. Regression analyses demonstrated a positive association between ACEs and antepartum health risks. However, a significant interaction between maternal ACEs and social support was also observed. Specifically, women exposed to high ACEs and low social support in pregnancy had high antepartum health risks. However, among mothers who had high ACEs but also high levels of social support, there was no association between ACEs and antepartum health risk. A history of ACEs can place mothers at risk of antepartum health complications. However, a resiliency effect was observed: women with a history of ACEs were buffered from experiencing antepartum health risks if they reported high levels of social support in pregnancy. PMID- 29594370 TI - Gender difference in the point prevalence, symptoms, comorbidity, and correlates of depression: findings from the Lagos State Mental Health Survey (LSMHS), Nigeria. AB - It is still unclear whether the gender difference in the rate of depression cuts across cultures or is specific to some depressive symptoms. This study evaluated the gender difference in current prevalence, symptoms, comorbidity, and correlates of depression in Lagos, Nigeria. A total of 11,246 adult participants (6525 females and 4712 males) in a face-to-face household survey were assessed for symptoms of depression. They were also assessed for symptoms of anxiety, somatic symptoms, alcohol and substance use disorders, and disability. The difference between the point prevalence for symptoms of depression in females (6.3%, s.e 0.3) and males (4.4%, s.e 0.3) was significant (OR 1.28, 95% CI 1.14 1.59). Compared to males, females had significantly higher rates for anhedonia (OR 1.20), hypersomnia (OR 2.15), fatigue (OR 1.49), guilt/worthless feeling (OR 1.41), poor concentration (OR 1.32), psychomotor retardation (OR 1.51), and suicidal ideation (OR 1.32). However, poor appetite (OR 0.69) and comorbidity with alcohol use (OR 0.25) was significantly lower in females compared to males. The significantly higher rates for depression in females were only restricted to below 45 years and higher socioeconomic status. Our study further contributed to the growing literature suggesting that the gender differences in rates of depression not only cut across many cultures, but most pronounced with atypical symptoms, not affected by recall bias and seems to disappear with increasing age. These need to be considered when formulating mental health policies for equitable and acceptable health services. PMID- 29594371 TI - B cell depletion reduces T cell activation in pancreatic islets in a murine autoimmune diabetes model. AB - AIMS/HYPOTHESIS: Type 1 diabetes is a T cell-mediated autoimmune disease characterised by the destruction of beta cells in the islets of Langerhans, resulting in deficient insulin production. B cell depletion therapy has proved successful in preventing diabetes and restoring euglycaemia in animal models of diabetes, as well as in preserving beta cell function in clinical trials in the short term. We aimed to report a full characterisation of B cell kinetics post B cell depletion, with a focus on pancreatic islets. METHODS: Transgenic NOD mice with a human CD20 transgene expressed on B cells were injected with an anti-CD20 depleting antibody. B cells were analysed using multivariable flow cytometry. RESULTS: There was a 10 week delay in the onset of diabetes when comparing control and experimental groups, although the final difference in the diabetes incidence, following prolonged observation, was not statistically significant (p = 0.07). The co-stimulatory molecules CD80 and CD86 were reduced on stimulation of B cells during B cell depletion and repopulation. IL-10-producing regulatory B cells were not induced in repopulated B cells in the periphery, post anti-CD20 depletion. However, the early depletion of B cells had a marked effect on T cells in the local islet infiltrate. We demonstrated a lack of T cell activation, specifically with reduced CD44 expression and effector function, including IFN gamma production from both CD4+ and CD8+ T cells. These CD8+ T cells remained altered in the pancreatic islets long after B cell depletion and repopulation. CONCLUSIONS/INTERPRETATION: Our findings suggest that B cell depletion can have an impact on T cell regulation, inducing a durable effect that is present long after repopulation. We suggest that this local effect of reducing autoimmune T cell activity contributes to delay in the onset of autoimmune diabetes. PMID- 29594373 TI - Comparison of Dimeglio and Pirani score in predicting number of casts and need for tenotomy in clubfoot correction using the Ponseti method. AB - PURPOSE: The Dimeglio and the Pirani scores are largely used to rate clubfoot at presentation and monitor correction. To date, the accuracy of these scores in predicting appropriate treatment is controversial. The aim of this study was to investigate the accuracy of Dimeglio and Pirani scores in predicting the number of casts and the need for tenotomy in clubfoot correction using the Ponseti method. METHODS: Ninety-one consecutive feet (54 patients; mean age at presentation: 28 +/- 15 days) undergoing clubfoot correction using the Ponseti method were prospectively followed from first casting to correction. All feet were scored according to the Dimeglio and Pirani score. The relationships between the two scores, the number of casts and the need for tenotomy were analysed. RESULTS: Initial correction was achieved in all feet. Both Dimeglio (r = .73; p value < .0005) and Pirani scores (r = .56; p value < .000) showed good association with the number of casts. Multiple linear regression showed a high collinearity of the two scores but a more significant contribution of the Dimeglio score. Among subcomponents, hindfoot score, midfoot score, varus and muscular abnormality were independent predictors of the number of casts. Both Dimeglio and Pirani scores were significantly associated with the need for tenotomy (p value = .0000), and odds ratios and cut-off points were calculated. The receiving operator curve (ROC) analysis showed slightly better performance of the Dimeglio in comparison with the Pirani score in predicting the need for tenotomy, but the difference between the two areas under the curve (AUC) was not significant (p = .48). CONCLUSIONS: A quite accurate prediction of the number of casts and the need for tenotomy can be performed in most cases. The Dimeglio score showed slightly better accuracy in predicting both steps of Ponseti treatment. PMID- 29594372 TI - Short-term outcomes of heart failure patients with reduced and preserved ejection fraction after acute decompensation according to the final destination after emergency department care. AB - AIMS: To compare short-term outcomes after an episode of acute heart failure (AHF) in patients with reduced and preserved ejection fractions (HFrEF, < 40%; and HFpEF, > 49%; respectively) according to their destinations after emergency department (ED) care. METHODS AND RESULTS: This secondary analysis of the EAHFE Registry (consecutive AHF patients diagnosed in 41 Spanish EDs) investigated 30 day all-cause mortality, in-hospital all-cause mortality, prolonged hospitalisation (> 7 days), and 30-day post-discharge ED revisit due to AHF, all cause death, and combined endpoint (ED revisit/death) in 5829 patients with echocardiographically documented HFrEF and HfpEF (HFrEF/HFpEF: 1,442/4,387). Adjusted ratios were calculated for patients admitted to internal medicine (IM), short stay unit (SSU), and discharged from the ED without hospitalisation (DEDWH) and compared with those admitted to cardiology. For HFrEF, the only significant differences were lower in-hospital mortality (OR = 0.26; 95% CI 0.08-0.81; p = 0.021) and prolonged hospitalisation (OR = 0.07; 95% CI 0.04-0.13; p < 0.001) related to SSU admission. For HFpEF, IM admission had a higher post-discharge 30 day mortality (HR = 1.85; 95% CI 1.05-3.25; p = 0.033) and combined endpoint (HR = 1.24; 95% CI 1.01-1.64; p = 0.044); SSU admission had a lower in-hospital mortality (OR = 0.43; 95% CI 0.23-0.80; p = 0.008) and prolonged hospitalisation (OR = 0.17; 95% CI 0.13-0.23; p < 0.001) but a higher post-discharge 30-day combined endpoint (HR = 1.29; 95% CI 1.01-1.64; p = 0.041); and DEDDWH had a lower 30-day mortality (HR = 0.46; 95% CI 0.28-0.75; p = 0.002) but higher post discharge ED revisit (HR = 1.62; 95% CI 1.31-2.00; p < 0.001). CONCLUSION: While HFrEF patients have similar short-term outcomes irrespective of the destination after ED care for an AHF episode, HFpEF patients present worse short-term outcomes when managed by non-cardiology departments, despite adjustment for different clinical patient profiles. Reasons for this heterogeneous specialty related performance should be investigated. PMID- 29594374 TI - [Pulmonary hypertension in connective tissue disease]. AB - Pulmonary arterial hypertension (PAH) is a major complication of systemic sclerosis (SSc) and screening is recommended for a timely initiation of disease targeted drug therapy to modify disease progression. Patients with SSc-PAH have a better prognosis when detected and treated early. The PAH can occur in all disease stages and subsets of SSc. Regular screening tests, which are indicative for PAH, e.g. echocardiography, diffusion capacity, brain natriuretic protein (BNP) and a 6-min walking test, are recommended to enhance the suspicion, since clinical symptoms are unspecific and occur late in the course of PAH. In patients with suspected PAH, the diagnosis should be confirmed by right heart catheterization. A multidisciplinary approach in expert centres including rheumatologists and respiratory physicians and cardiologists specialized in pulmonary hypertension is mandatory for management of patients with SSc at risk for or with manifest pulmonary arterial hypertension.

AB - This research describes a nanowire network-based method for detecting the activity of myeloperoxidase (MPO), a biomarker of acute coronary syndromes (ACS). Trimetallic CuPdPt nanowire networks (CuPdPt NWNWs) were prepared by a one-step chemical reduction method. The metallic precursors quickly form nanowire network structures without the need for additional capping agents or surfactants. This process creates a product with a clean surface. The NWNWs were dropped onto a glassy carbon electrode (GCE) to obtain a sensor with good catalytic activity towards the reduction of hydrogen peroxide (H2O2), which was used as an electrochemical probe working at -0.4 V (vs. SCE). It also provided a large surface for further modification. Next, an antibody against MPO was immobilized on the modified GCE via the stable conjunction between Cu, Pt, Pd and amino groups. Upon binding of MPO to the antibody on the GCE, the current response to H2O2 was reduced by 35 MUA.cm-2. The immunosensor had a linear response within the 100 fg.mL-1 to 50 ng.mL-1 MPO concentration range and a 33 fg.mL-1 detection limit (at an S/N ratio of 3). The recovery of spiked serum samples ranged from 99.8 to 103.6%. This result suggests that the method can be applied to the quantitation of MPO in human serum samples. Graphical abstract A trimetallic CuPdPt nanowire networks was placed on a glassy cabon electrode (GCE) to design an immunosensor for myeloperoxidase (MPO), a biomarker for the acute coronary syndrome (ACS). Antibody against MPO was immobilized on the network via conjugation between Cu, Pt, Pd and amino groups. Amperometric i-t measurements were conducted to quantify the amount of MPO that binds to the antibody on the surface of the modified GCE. PMID- 29594376 TI - Loop-mediated isothermal amplification for visual detection of Vibrio parahaemolyticus using gold nanoparticles. AB - Loop-mediated isothermal amplification (LAMP) eradicates the need of thermocycler in DNA amplification. Signals are usually obtained via fluorometry or turbidimetry, but such methods need improvement in order to become more effortless and reliable. The authors describe a set of six specific primers targeting the species-specific tlh gene of Vibrio parahaemolyticus which were used in accelerated LAMP reaction. Gold nanoparticles (AuNPs) were functionalized with streptavidin (Avidin-AuNPs), and engineered to signal the LAMP reaction. Two of the loop primers for LAMP were biotinylated and then can produce a DNA that can cause clusterization of Avidin-AuNPs based on the formation of avidin-biotin complex. This leads to a color change of the solution from red to blue. Amplification is completed within 30 min and can be visually detected within 5 min. The detection limit of the method is found to be 8.6 cfu per reaction. This visual detection scheme does not require any fluorescent reagents and detection instruments. Conceivably, the method has a wide scope because such Avidin-AuNPs can be used as nanoprobes for a variety of other LAMP products. This rapid and universal strategy holds promise in point of care testing and food testing, particularly in resource-limited regions. Graphical abstract Six specific primers (two of them are biotinylated) were used to realize the accelerated Loop-Mediated Isothermal Amplification. Streptavidin modified gold nanoparticles (Avidin-AuNPs) cluster on the DNA products, leading to the apparent change of color from red to blue, which is readily identified even by unaided eye. PMID- 29594377 TI - A gold electrode modified with a nanoparticulate film composed of a conducting copolymer for ultrasensitive voltammetric sensing of hydrogen peroxide. AB - A film consisting of poly(gamma-glutamic acid) modified with 3-aminothiophene (ATh-gamma-PGA) was prepared by macromolecular self-assembly and electropolymerization. ATh-gamma-PGA is amphiphilic and electrically conductive. The copolymers undergo self-assembly to form nanoparticles (NPs) on decreasing the pH value of an aqueous solution. A conducting film of NPs was formed on the surface of a gold electrode by casting the ATh-gamma-PGA NPs and subsequently electropolymerizing the thiophene units. Next, horseradish peroxidase and Nafion were cast onto the film to obtain an enzymatic biosensor for H2O2. Due to the electropolymerization step, a cross-conjugated polymer network is created that improves electron transfer rates and thus enhances the response. This endows the biosensor with high sensitivity. Two linear ranges are present, the first ranging from 1 * 10-11 to 1 * 10-8 mol.L-1, and the second from 1 * 10-8 to 1 * 10-5 mol.L-1. The detection limit is as low as 3 * 10-12 mol.L-1. The sensor is stable, repeatable, and was successfully applied to the determination of H2O2 in a commercial disinfecting solution. Graphical abstract Preparation of a conducting nanoparticle (NP) film on the gold electrode (GE) by self-assembly of poly(gamma-glutamic acid) that was modified with electroactive 3-aminothiophene (ATh-gamma-PGA).

PMID- 29594378 TI - Chemiluminescence assay for detection of 2-hydroxyfluorene using the G-quadruplex DNAzyme-H2O2-luminol system. AB - A chemiluminescence (CL) based assay is described for the determination of the environmental pollutant 2-hydroxyfluorene (2-HOFlu) which is found to inhibit the CL of a system composed of the G-quadruplex/hemin complex (a DNAzyme), H2O2, and luminol. The G-rich aptamer PW17 is transformed to a potassium(I)-stabilized G quadruplex-hemin complex which displays peroxidase-like activity to catalyze the oxidation of luminol by H2O2 which is accompanied by strong blue CL emission. On addition of 2-HOFlu, it will participate in the G-quadruplex DNAzyme-mediated oxidation by H2O2. As a result, CL intensity is decreased. The difference in CL intensity (DeltaI) before and after addition of 2-HOFlu serves as the signal for its quantitation. In water of pH 9.0, a linear relationship is found for the 1 nM to 1 MUM concentration range, with a 0.2 nM detection limit. The assay is highly selective over other fluorene derivatives. It was successfully applied to the determination of 2-HOFlu in spiked lake water samples. The method is rapid, cost effective and convenient. Conceivably, it has a wide scope in that it may be applied to other target pollutants for which G-quadruplexes are available. Graphical abstract A chemiluminescence (CL) assay is described for the determination of the environmental pollutant 2-hydroxyfluorene (2-HOFlu) based on the inhibition of the CL system composed of the G-quadruplex/hemin complex (a DNAzyme), H2O2, and luminol. PMID- 29594379 TI - An oligosorbent-based aptamer affinity column for selective extraction of aflatoxin B2 prior to HPLC with fluorometric detection. AB - The article describes an aptamer affinity column for selective solid-phase extraction of aflatoxin B2 (AFB2). Amino-modified aptamer against AFB2 was immobilized on CNBr-activated Sepharose through a covalent bond. The effects of oligosorbents based on 3'- or 5'-amino-modified sequences with a C6 or a C7 spacer arm were evaluated by UV spectroscopy at 260 nm. The extraction recovery was evaluated by HPLC with fluorometric detection. The extraction of AFB2 was optimized. Under the optimum conditions, the aptamer affinity column has a linear response to AFB2 in the range of 0.5-80 ng, with a capacity of 84.6 ng. Control supports without immobilized aptamers and a nonspecific oligosorbent immobilized with a negative control oligonucleotide were studied in order to demonstrate selectivity. The method was tested with spiked peanut sample (0.5-50 MUg.kg-1 AFB2) and gave average recoveries of 80.9% and a mean relative standard deviation of 1.9%. The limit of detection is 25 pg.mL-1. This is much lower than the maximum residue limits suggested by the European Union. The columns can be re used up to five times without any loss of performance. The oligosorbent was also applied to clean-up of AFB2 from peanut sample extracts before HPLC analysis. Results were further confirmed by ultra-fast liquid chromatography with tandem mass spectrometry. Conceivably, the method may also be applied to other samples, such as food, agricultural products, and traditional Chinese medicines.

AB - Four biomass wastes (rice husk, coffee husk, coarse wool, and landfill wood) were added with biochar and polypropylene (PP) to manufacture biocomposites. Individual biomasses were tested for their combustion behavior using cone calorimeter. Biocomposites were analyzed for their fire/thermal, mechanical, and morphological properties. Wood had the most desirable comprehensive effect on both the mechanical and fire properties of composites. In particular, wood and biochar composite exhibited the highest values of tensile/flexural properties with a relatively low peak heat release rate. In general, application of waste derived biochar and biomasses drastically reduced the susceptibility of neat PP towards fire.

AB - The authors describe the preparation of Fe3O4 nanoparticles coated with poly(p phenylenediamine-co-thiophene). The resulting nanoparticles (NPs) are shown to be viable sorbents for use in magnetic solid-phase extraction (MSPE) of organophosphorus pesticides (OPPs). The coated NPs were characterized by BET, FTIR, scanning electron microscopy and transmission electron microscopy. Following sorption of OPPs and subsequent desorption with dichloromethane, the OPPs were quantified by GC in combination with FID. Under optimal conditions, the preconcentration factors range from 118 to 163. Other figures of merit include (a) a linear response between 0.3 and 500 ng mL-1; (b) detection limits (at an S/N ratio of 3) between 0.1 and 0.3 ng mL-1, and (c) a precision (for n = 5) between 4.7 and 8.1% at concentration levels of 1, 10 and 100 ng mL-1). The nanocomposites can be reused up to 8 times. The method was applied to the analysis of spiked environmental water samples and fruit juices and gave relative recoveries in the range of 88.1 to 99.2%.

AB - A dually emitting quantum dot nanohybrid was designed for the fluorometric 2 wavelength determination of ascorbic acid (AA). The nanohybrid consists of red emitting CdTe quantum dots (QDs) covalently linked to the surface of silica nanoparticles containing green-emitting CdSe QDs. The fluorescence of the red emitting CdTe QDs (peaking at 616 nm) is first quenched by addition of KMnO4 due to oxidation under formation of CdTeO3 and TeO2. On addition of AA, the red fluorescence is restored due to the reduction of surface CdTeO3/TeO2 to form CdTe. The green fluorescence of the green-emitting CdSe QDs (peaking at 522 nm), in contrast, remains constant and its intensity serves as a reference signal. Both kinds of QDs can be photoexcited at 380 nm. An easily distinguishable transition in fluorescence (from green to orange-red) can be observed on increasing the amount of added AA. Under optimal conditions, the ratio of the intensities of the red and the green fluorescence increases linearly in the 0.1 to 5.0 MUM AA concentration range, and the detection limit is as low as 35 nM. The assay was successfully applied to the quantitation of AA in (spiked) fruit juice samples. Graphical abstract A new dually emitting CdSe@SiO2@CdTe nanohybrid was designed for ratiometric ultrasensitive fluorometric detection of ascorbic acid in fruit juice samples.

AB - This paper describes a voltammetric method for sensitive determination of specific sequences of DNA. The assay is based on three-dimensional nitrogen-doped graphene (3D-NG) which, due to its excellent electrical conductivity, provides a favorable microenvironment to retain the activity of immobilized probe single stranded DNA and also facilitates electron transfer. The free-standing 3D-NG electrode was characterized by scanning electron microscopy, Raman and X-ray photoelectron spectroscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. Differential pulse voltammetry was applied to monitor DNA hybridization using Methylene Blue as an electrochemical indicator. Under optimal conditions, the peak currents (best measured at 0.28 V vs. Ag/AgCl) increase linearly with the logarithm of the concentrations of ssDNA in the 10 f. to 10 nM concentrations range, with a 3.5 f. detection limit (at a signal/noise ratio of 3). The biosensor exhibits good selectivity for ssDNA and can distinguish even single-base mismatches. The capability of the method was tested with spiked serum samples, and excellent reproducibility and stability is found. This indicates that the strategy is promising for use in clinical applications. Graphical abstract Three-dimensional nitrogen-doped graphene as an innovative and simple electrochemical DNA biosensor was fabricated and used in a biosensor that shows high sensitivity and good performance in the determination of target DNA in human serum samples.

AB - In this information epidemiology (infodemiology) study, we describe the online public interest about the issue of femicide in Brazil and analyze the relationship between search queries and femicide trends from 2004 to 2015. We showed that information-seeking behavior for femicide in the Brazilian states has been strongly influenced by female homicide rates. Educational and policy-related interventions are needed to improve the population's knowledge and attitude toward femicide. PMID- 29594385 TI - Cripto-1 is overexpressed in carcinoma ex pleomorphic adenoma of salivary gland. AB - INTRODUCTION: Cripto-1 is a member of the epidermal growth factor-Cripto-1/FRL 1/Cryptic family. Besides being critical for early embryonic development, Cripto 1 is also associated with the development and behavior of several cancers. OBJECTIVE: We analyzed the immunoexpression of Cripto-1 in normal salivary glands (NSGs), pleomorphic adenomas (PAs), and carcinoma ex pleomorphic adenomas (CaExPAs) of salivary glands. METHODS: A total of 12 NSGs, 16 PAs and 12 CaExPAs underwent immunohistochemical study by the polymeric biotin-free technique. Immunopositive cells were evaluated semiquantitatively (scores 0-3). For statistical analysis, Mann-Whitney and Kruskal-Wallis tests were performed and a significance level of p <= 0.05 was established. RESULTS: Most CaExPAs (n = 10) were strong positive (score 3) for Cripto-1, and only three cases of PAs and two specimens of NSGs exhibited some expression (score 1), being statistically significant these findings (p < 0.001). No difference between the expression of this protein in tumors of major and minor salivary glands was observed. Overexpression was found mainly in cases of CaExPAs with invasive growth (n = 8) when compared to those without capsular invasion (intracapsular pattern) (p = 0.036). Patients with or without lymph node metastasis showed no difference (p = 0.294). CONCLUSION: The results revealed a significantly higher expression of Cripto-1 in CaExPA compared to PA and NSG, suggesting this protein is possibly deregulated in PA malignant transformation. Furthermore, the increased expression of this protein is associated with a more aggressive behavior (invasive growth) in salivary gland tumors. PMID- 29594386 TI - Mutational analysis uncovers monogenic bone disorders in women with pregnancy associated osteoporosis: three novel mutations in LRP5, COL1A1, and COL1A2. AB - : Pregnancy was found to be a skeletal risk factor promoting the initial onset of previously unrecognized monogenic bone disorders, thus explaining a proportion of cases with pregnancy-associated osteoporosis. Therapeutic measures should focus in particular on the normalization of the disturbed calcium homeostasis in order to enable the partial skeletal recovery. INTRODUCTION: Pregnancy-associated osteoporosis (PAO) is a rare skeletal condition, which is characterized by a reduction in bone mineral density (BMD) in the course of pregnancy and lactation. Typical symptoms include vertebral compression fractures and transient osteoporosis of the hip. Since the etiology is not well understood, this prospective study was conducted in order to elucidate the relevance of pathogenic gene variants for the development of PAO. METHODS: Seven consecutive cases with the diagnosis of PAO underwent a skeletal assessment (blood tests, DXA, HR-pQCT) and a comprehensive genetic analysis using a custom-designed gene panel. RESULTS: All cases showed a reduced BMD (DXA T-score, lumbar spine - 3.2 +/- 1.0; left femur - 2.2 +/- 0.5; right femur - 1.9 +/- 0.5), while the spine was affected more severely (p < 0.05). The trabecular and cortical thickness was overall reduced in HR-pQCT, while the trabecular number showed no alterations in most cases. The genetic analysis revealed three novel mutations in LRP5, COL1A1, and COL1A2. CONCLUSION: Our data show that previously unrecognized monogenic bone disorders play an important role in PAO. Pregnancy should be considered a skeletal risk factor, which can promote the initial clinical onset of such skeletal disorders. The underlying increased calcium demand is essential in terms of prophylactic and therapeutic measures, which are especially required in individuals with a genetically determined low bone mass. The implementation of this knowledge in clinical practice can enable the partial recovery of the skeleton. Consistent genetic studies are needed to analyze the frequency of pathogenic variants in women with PAO. PMID- 29594388 TI - The insulin-degrading enzyme is an allosteric modulator of the 20S proteasome and a potential competitor of the 19S. AB - The interaction of insulin-degrading enzyme (IDE) with the main intracellular proteasome assemblies (i.e, 30S, 26S and 20S) was analyzed by enzymatic activity, mass spectrometry and native gel electrophoresis. IDE was mainly detected in association with assemblies with at least one free 20S end and biochemical investigations suggest that IDE competes with the 19S in vitro. IDE directly binds the 20S and affects its proteolytic activities in a bimodal fashion, very similar in human and yeast 20S, inhibiting at (IDE) <= 30 nM and activating at (IDE) >= 30 nM. Only an activating effect is observed in a yeast mutant locked in the "open" conformation (i.e., the alpha-3DeltaN 20S), envisaging a possible role of IDE as modulator of the 20S "open"-"closed" allosteric equilibrium. Protein protein docking in silico proposes that the interaction between IDE and the 20S could involve the C-term helix of the 20S alpha-3 subunit which regulates the gate opening of the 20S. PMID- 29594387 TI - Redox-dependent thiol modifications: implications for the release of extracellular vesicles. AB - Extracellular vesicles (EVs), including microvesicles and exosomes, are emerging as important regulators of homeostasis and pathophysiology. During pro inflammatory and pro-oxidant conditions, EV release is induced. As EVs released under such conditions often exert pro-inflammatory and procoagulant effects, they may actively promote the pathogenesis of chronic diseases. There is evidence that thiol group-containing antioxidants can prevent EV induction by pro-inflammatory and oxidative stimuli, likely by protecting protein thiols of the EV-secreting cells from oxidation. As the redox state of protein thiols greatly impacts three dimensional protein structure and, consequently, function, redox modifications of protein thiols may directly modulate EV release in response to changes in the cell's redox environment. In this review article, we discuss targets of redox dependent thiol modifications that are known or expected to be involved in the regulation of EV release, namely redox-sensitive calcium channels, N ethylmaleimide sensitive factor, protein disulfide isomerase, phospholipid flippases, actin filaments, calpains and cell surface-exposed thiols. Thiol protection is proposed as a strategy for preventing detrimental changes in EV signaling in response to inflammation and oxidative stress. Identification of the thiol-containing proteins that modulate EV release in pro-oxidant environments could provide a rationale for broad application of thiol group-containing antioxidants in chronic inflammatory diseases. PMID- 29594389 TI - Follistatin-like 1 in development and human diseases. AB - Follistatin-like 1 (FSTL1) is a secreted glycoprotein displaying expression changes during development and disease, among which cardiovascular disease, cancer, and arthritis. The cardioprotective role of FSTL1 has been intensively studied over the last years, though its mechanism of action remains elusive. FSTL1 is involved in multiple signaling pathways and biological processes, including vascularization and regulation of the immune response, a feature that complicates its study. Binding to the DIP2A, TLR4 and BMP receptors have been shown, but other molecular partners probably exist. During cancer progression and rheumatoid arthritis, controversial data have been reported with respect to the proliferative, apoptotic, migratory, and inflammatory effects of FSTL1. This controversy might reside in the extensive post-transcriptional regulation of FSTL1. The FSTL1 primary transcript also encodes for a microRNA (miR-198) in primates and multiple microRNA-binding sites are present in the 3'UTR. The switch between expression of the FSTL1 protein and miR-198 is an important regulator of tumour metastasis and wound healing. The glycosylation state of FSTL1 is a determinant of biological activity, in cardiomyocytes the glycosylated form promoting proliferation and the non-glycosylated working anti-apoptotic. Moreover, the glycosylation state shows differences between species and tissues which might underlie the differences observed in in vitro studies. Finally, regulation at the level of protein secretion has been described. PMID- 29594390 TI - Voltammetric sensing based on the use of advanced carbonaceous nanomaterials: a review.

AB - A cellulose paper was modified with an aptamer against methamphetamine on either carbon dots (CDs) or on multichannel carbon nanotubes (CNTs). The resulting sorbent was applied to the extraction of METH from blood or saliva. The METH loaded paper than also was directly applied as a paper spray ionization source in ion mobility spectrometry. The carbon nanomaterial enhances sensitivity, and the aptamer enhances selectivity. The materials were covalently bound to the paper on one side, while the aptamer was immobilized on the other. After optimization of the extraction process and instrumental parameters, the limits of detection when using the aptamer-CNT modified paper are 0.6 ng.mL-1 for saliva, and 0.45 ng.mL-1 for plasma. The respective values when using aptamer-CD modified paper are 1.5 ng.mL-1 for saliva and 0.9 ng.mL-1 for plasma. Calibration plots are linear in the 2 to 150 ng.mL-1 METH concentration range for saliva, and in the 1.5 to 200 ng.mL-1 concentration ranges for blood when using the aptamer-CNT based method. When using the aptamer-CDs, the dynamic ranges extend from 5 to 200 ng.mL-1 and from 3 to 250 ng.mL-1, respectively. The method was applied to the determination of METH in real samples of saliva and blood, and the accuracy of the method was confirmed by comparison of the results with data analyzed by GC-MS.

AB - The authors describe an aptamer based assay for the food mycotoxin ochratoxin A (OTA). It is based on the use of exonuclease III (Exo III) which assists in signal amplification, and of single-walled carbon nanohorns (SWCNHs) which act as quenchers of fluorescence. The detection scheme employs a hairpin probe (HP) and a signal probe (SP) labeled with carboxyfluorescein (FAM) at its 5'-end. The fluorescence of intact SPs (best measured at excitation/emission wavelengths of 495/518 nm) is quenched by SWCNHs. The HP contains the OTA-specific aptamer sequence and is partially complementary to the SP. After addition of OTA, the aptamer binds OTA and thus exposes a single-stranded sequence that can hybridize with the SP. Exo III digests the SP to liberate the free fluorophore labels. The damaged SPs no longer are adsorbed by the SWCNHs so that fluorescence is no longer quenched. The method has a detection range that is linear from 10 nM to 1000 nM (with a correlation coefficient of 0.997). The limit of detection (LOD), calculated on the basis of a signal to noise ratio of 3, is 4.2 nM. The procedure was validated by the quantitation of OTA in spiked real samples and were found to be free of interference by the sample matrix. Recoveries ranged from 93.8 to 113.0% in beer and from 92.0 to115.9% in red wine. Graphical abstract After adding ochratoxin A (OTA), the aptamer region in hairpin probe (HP) combined with OTA and thus exposed a single-stranded sequence to hybridize with signal probe (SP). Exonuclease III (Exo III) digested SP to liberate the free fluorophore (FAM).

AB - Structural magnetic resonance imaging (MRI) studies reported gray matter (GM) loss in bipolar disorder (BD) in cingulate cortices, key regions subserving emotional regulation and cognitive functions in humans. The aim of this study was to further explore cingulate GM volumes in a sizeable group of BD patients with respect to healthy controls, particularly investigating the impact of gender and clinical variables. 39 BD patients (mean Age = 48.6 +/- 9.7, 15 males and 24 females) and 39 demographically matched healthy subjects (mean Age = 47.9 +/- 9.1, 15 males and 24 females) underwent a 1.5T MRI scan. GM volumes within the cingulate cortex were manually detected, including anterior and posterior regions. BD patients had decreased left anterior cingulate volumes compared with healthy controls (F = 6.7, p = 0.01). Additionally, a significant gender effect was observed, with male patients showing reduced left anterior cingulate cortex (ACC) volumes compared to healthy controls (F = 5.1, p = 0.03). Furthermore, a significant inverse correlation between right ACC volumes and number of hospitalizations were found in the whole group of BD patients (r = - 0.51, p = 0.04) and in male BD patients (r = - 0.88, p = 0.04). Finally, no statistically significant correlations were observed in female BD patients. Our findings further confirm the putative role of the ACC in the pathophysiology of BD. Interestingly, this study also suggested the presence of gender-specific GM volume reductions in ACC in BD, which may also be associated to poor outcome. PMID- 29594395 TI - [Obstacles and perspectives of new antimicrobial concepts within research and development]. AB - Antimicrobial resistance (AMR) has developed into a serious problem for the healthcare sector worldwide. Research on fundamentally novel antibiotics has been insufficient for decades and only a few new compounds have reached the market. Thus, the pressure to implement novel and effective concepts for the reduction of infections through problematic pathogens has dramatically increased. This demand has been recognized by politicians and comprehensive national and international funding programs have been launched. A major role of many funding lines is the investigation and development of therapeutics exerting a novel mechanism of action and/or minimizing the frequency of resistance. In addition to the actual clinical pipeline, this article lists selected examples from research and early development with a special focus on antibiotics. Moreover, alternative approaches like antivirulence and phage therapy as well as immunomodulation are summarized. AMR is no longer solely a healthcare policy, but is of societal significance as a whole. A consolidation of infrastructures and public-private partnerships, a reduction of regulatory obstacles and a continuous pursuit of innovations for antimicrobial therapy are urgently needed.

AB - The authors have immobilized nanowires made from zirconium glycerolate (ZrGly) on magnetite (Fe3O4) nanoparticles by applying a solvothermal growth process using metal-glycerolate as a precursor. The structure and the dissolution recrystallization mechanism of the resulting Fe3O4@ZrGly composite were investigated by attenuated total reflection-FTIR, energy-dispersive X-ray analysis, thermogravimetric analysis and solid-state cross polarization/magic angle spinning 13C NMR spectroscopy. The interaction between the zirconium glycerolate in Fe3O4@ZrGly and cis-diols leads to efficient adsorption of riboncleosides which then can be quantified by HPLC with UV detection. The sorbent was successfully applied to the selective enrichment of adenosine, cytidine, uridine and guanosine from spiked human urine samples. The detection limit of the method is in the range from 1.7 to 19 ng.mL-1 of nucleosides in spiked human urine, with relative standard deviations of lower than 12.4% and recoveries ranging from 90.6 to 113%. Graphical abstract Fe3O4@ZrGly with high selectivity towards ribonucleosides was designed and applied for quantitation of urinary ribonucleosides.

AB - The effect of graphene nanosheets on the glucose sensing performance of CuO powders was investigated. CuO and graphene-modified CuO nanoparticles (NPs) were fabricated by microwave-assisted synthesis and characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. The material was placed on a glassy carbon electrode (GCE) which then was characterized by cyclic voltammetry and chronoamperometry with respect to the capability of sensing glucose both at pH 13 and pH 7.4. The results revealed that the modified GCE has a fast and selective linear response to glucose at pH 13 that covers the 0.21 MUM to 12 mM concentration range, with a 0.21 MUM low detection limit. The presence of graphene nanosheets results in an improved sensitivity which is to 700 MUA mM-1 cm-2. In solution of pH 7.4, the respective data are a linear analytical range from 5 to 14 mM; a 5 MUM LOD and a sensitivity of 37.63 MUA mM-1 cm-2 at working potential of -0.05 V (vs. Ag/AgCl) and scan rate of 50 mV s-1. Ascorbic acid, dopamine, uric acid, sucrose, maltose and fructose do not interfere. Graphical abstract ?.

AB - This article describes an impedimetric aptasensor for the prostate specific antigen (PSA), a widely accepted prostate cancer biomarker. A glassy carbon electrode (GCE) was modified with titanium oxide nanoparticles (TiO2) and silk fibroin nanofiber (SF) composite. The aptasensor was obtained by immobilizing a PSA-binding aptamer on the AuNP-modified with 6-mercapto-1-hexanol. The single fabrication steps were characterized by cyclic voltammetry and electrochemical impedance spectroscopy. The assay has two linear response ranges (from 2.5 fg.mL 1 to 25 pg.mL-1, and from 25 pg.mL-1 to 25 ng.mL-1) and a 0.8 fg.mL -1 detection limit. After optimization of experimental conditions, the sensor is highly selective for PSA over bovine serum albumin and lysozyme. It was successfully applied to the detection of PSA in spiked serum samples. Graphical abstract Schematic of the fabrication of an aptasensor for the prostate specific antigen (PSA). It is based on the use of a glassy carbon electrode modified with gold nanoparticles and titanium oxide-silk fibroin. The immobilization process of aptamer and interaction with PSA were followed by electrochemical impedance spectroscopy technique.

PMID- 29594400 TI - A cascade amplification strategy of catalytic hairpin assembly and hybridization chain reaction for the sensitive fluorescent assay of the model protein carcinoembryonic antigen. AB - A cascade nucleic acid amplification strategy is presented for fluorometric aptamer based determination of the model protein carcinoembryonic antigen (CEA). Amplification is accomplished by combining catalytic hairpin assembly (CHA) and hybridization chain reaction (HCR). In this assay, a specially designed single stranded DNA containing the aptamer sequence (AS) specific for CEA is hybridized with an inhibitor strand (IS) to form a double-stranded DNA (IS@AS). In the presence of CEA, it will recognize and bind to the AS strand which causes the release of IS. By introducing two DNA hairpins (H1 and H2; these containing complementary sequences) CHA will be activated via the hybridization reactions of H1 and H2. This is accompanying by the formation of a double-stranded DNA (H1-H2) and the release of CEA@AS. The liberated CEA@AS further drives successive recycling of the CHA, thereby generating further copies of H1-H2. The resultant H1-H2 hybrids act as primers and trigger HCR with the help of other two DNA hairpins (H3 and H4) containing G-rich toehold at the 5'-terminus and 3'-terminus of H3 and H4, respectively. The fluorescent probe N-methyl mesoporphyrin IX (NMM) is finally intercalated into the G-rich domains of the long DNA nanostructures due to formation of G-quadruplex structures. This generates a fluorescent signal (best measured at excitation/emission wavelengths of 399/610 nm) that increases with the concentration of target (CEA). This aptamer-based fluorescence assay is highly sensitive and has a linear range that covers the 1 pg.mL-1 to 2 ng.mL-1 CEA concentration range, with a 0.3 pg.mL-1 detection limit. Graphical abstract By integrating catalytic hairpin assembly (CHA) and hybridization chain reaction (HCR) for effective signal enhancement, a novel cascade amplification strategy is presented to develop a sensitive and selective fluorescent method for the assay of the model protein carcinoembryonic antigen (CEA).

AB - OBJECTIVES: To examine radiation dose levels of CT-guided interventional procedures of chest, abdomen, spine and extremities on different CT-scanner generations at a large multicentre institute. MATERIALS AND METHODS: 1,219 CT guided interventional biopsies of different organ regions ((A) abdomen (n=516), (B) chest (n=528), (C) spine (n=134) and (D) extremities (n=41)) on different CT scanners ((I) SOMATOM-Definition-AS+, (II) Volume-Zoom, (III) Emotion6) were included from 2013-2016. Important CT-parameters and standard dose-descriptors were retrospectively examined. Additionally, effective dose and organ doses were calculated using Monte-Carlo simulation, following ICRP103. RESULTS: Overall, radiation doses for CT interventions are highly dependent on CT-scanner generation: the newer the CT scanner, the lower the radiation dose imparted to patients. Mean effective doses for each of four procedures on available scanners are: (A) (I) 9.3mSv versus (II) 13.9mSv (B) (I) 7.3mSv versus (III) 11.4mSv (C) (I) 6.3mSv versus (II) 7.4mSv (D) (I) 4.3mSv versus (II) 10.8mSv. Standard dose descriptors [standard deviation (SD); CT dose indexvol (CTDIvol); dose-length product (DLPbody); size-specific dose estimate (SSDE)] were also compared. CONCLUSION: Effective dose, organ doses and SSDE for various CT-guided interventional biopsies on different CT-scanner generations following recommendations of the ICRP103 are provided. New CT-scanner generations involve markedly lower radiation doses versus older devices. KEY POINTS: * Effective dose, organ dose and SSDE are provided for CT-guided interventional examinations. * These data allow identifying organs at risk of higher radiation dose. * Detailed knowledge of radiation dose may contribute to a better individual risk stratification. * New CT-scanner generations involve markedly lower radiation doses compared to older devices.

AB - OBJECTIVES: To evaluate the diagnostic accuracy of contrast-enhanced (CE) cone beam breast computed tomography (CBBCT) in dense breast tissue and compare it to non-contrast (NC) CBBCT, mammography (MG) and magnetic resonance imaging (MRI). METHODS: This prospective institutional review board-approved study included 41 women (52 breasts) with American College of Radiology (ACR) density types c or d and Breast Imaging Reporting and Data System (BI-RADS) 4 or 5 assessments in MG or ultrasound (US). Imaging modalities were independently evaluated by two blinded readers. RESULTS: A total of 100 lesions (51 malignant, 6 high-risk, and 43 benign) were identified. For readers 1/2, respectively, and p values comparing CE-CBBCT to other modalities: diagnostic accuracy (AUC) for CE-CBBCT was 0.83/0.77, for MRI 0.88/0.89 (p = 0.2272/0.002), for NC-CBBCT 0.73/0.66 (p = 0.038/ 0.0186) and for MG 0.69/0.64 (p = 0.081/0.0207). CE-CBBCT sensitivity (0.88/0.78) was 37-39% higher in comparison to MG (0.49/0.41, p < 0.001 both) but inferior to MRI (0.98/0.96, p = 0.0253/0.0027). CE-CBBCT specificity (0.71/0.71) was numerically higher compared to MRI (0.61/0.69, p = 0.0956/0.7389). CONCLUSIONS: CBBCT diagnostic performance varied with the respective reader and experience. CE-CBBCT improved AUC and sensitivity in comparison to MG and NC CBBCT, and was comparable to MRI in dense breast tissue. In tendency, specificity was higher for CE-CBBCT than MRI. KEY POINTS: * CE-CBBCT diagnostic accuracy (AUC) was comparable to MRI in dense breasts. * CE-CBBCT improved sensitivity and AUC in comparison to MG and NC-CBBCT. * CE-CBBCT has inferior sensitivity but higher specificity than MRI. * CE-CBBCT is a potential imaging alternative for patients with MRI contraindications.

AB - Ustilago esculenta, resembling a fungal endophyte in Zizania latifolia, inhibits the host plant flowering and induces the host stems to swell and form edible galls. It is well believed that when and how the fungus infects and proliferates in the host plants during the host development is of importance in the edible gall formation. Mitogen-activated protein kinases (MAPKs) have been found to play an important role in sensing environment cues and regulating infection. Two MAPK genes UeKpp2 and UeKpp6 from U. esculenta were cloned and suggested to be involved in the Fus3/Kss1 pathway by a phylogenetic analysis with the neighbor joining method. Quantitative RT-PCR (qRT-PCR) analyses indicated that expression of UeKpp2 and UeKpp6 were induced during mating and infection processes, and their expression patterns displayed differentially under different carbon and nitrogen sources. In addition, subcellular localization of UeKpp2 or UeKpp6 fused with the reporter green fluoresce protein was observed by confocal laser scanning microscope, and yeast two-hybrid assays were carried out. Results showed that both UeKpp2 and UeKpp6 were located in cytoplasm and interacted with UePrf1, indicating their involvement in hyphal growth and host-pathogen regulation. Only UeKpp2 but not UeKpp6 interacted with the upstream MAPK kinase UeFuz7, implying an additional MAPK pathway, in which UeKpp6 involved, existed.

PMID- 29594405 TI - Quantitative qPCR Analysis of Ruminal Microorganisms in Beef Cattle Grazing in Pastures in the Rainy Season and Supplemented with Different Protein Levels. AB - We tested the hypothesis that supplementation with three protein levels improves fermentation parameters without changing the rumen microbial population of grazing beef cattle in the rainy season. Four rumen-cannulated Nellore bulls (432 +/- 21 kg of body weight) were used in a 4 * 4 Latin square design with four supplements and four experimental periods of 21 days each. The treatments were mineral supplement (ad libitum) and supplements with low, medium (MPS), and high protein supplement (HPS), supplying 106, 408, and 601 g/day of CP, respectively. The abundance of each target taxon was calculated as a fraction of the total 16S rRNA gene copies in the samples, using taxon-specific and domain bacteria primers. Supplemented animals showed lower (P < 0.05) proportions of Ruminococcus flavefaciens and greater (P < 0.05) proportions of Ruminococcus albus and Butyrivibrio fibrisolvens than animals that received only the mineral supplement. The HPS supplement resulted in higher (P < 0.05) proportions of Fibrobacter succinogenes, R. flavefaciens, and B. fibrisolvens and lower (P < 0.05) proportions of R. albus than the MPS supplement. Based on our results, high protein supplementation improves the ruminal conditions and facilitates the growth of cellulolytic bacteria in the rumen of bulls on pastures during the rainy season. PMID- 29594406 TI - Graphene and graphene oxide as a solid matrix for extraction of membrane and membrane-associated proteins. AB - The extraction of membrane proteins remain a challenge due to innate hydrophobicity, dynamic discrepancy, and restrain effect of membrane lipids. Nanomaterials with high surface area have competency of hydrophobic-hydrophobic lipid interactions. It is shown here that both graphene and graphene oxide dissolved in solubilization buffer are viable sorbents for efficient extraction of membrane proteins. LC-MS/MS analysis further revealed that graphene (50-200 nm) and graphene oxide (50-200 nm) can enrich more kinds of membrane proteins than a commercially available kit. Graphene was further applied to the enrichment of membrane proteins of normal cells as well as cancer cells, and 1079 and 872 proteins were identified, respectively, among which 56.5% and 60.5% were membrane proteins. In particular, 241 proteins were significantly regulated in cancer cells. Gene expression of 15 proteins was verified by qRT-PCR, and 4 of them were further quantified by immunoassay. These data collectively demonstrate that graphene has great potential to improve membrane protein extractions and thus can serve downstream cancer proteomics. Graphical abstract Two dimensional carbon nanomaterials, including graphene and graphene oxide, were employed as solid matrix to avoid lipid bilayer interference and enhance the extraction efficiency of membrane and membrane associated proteins. The strategy will benefit downstream membrane proteomics analysis. PMID- 29594407 TI - [Fatal flecainide intoxication in a 17-year-old girl]. AB - A 17-year-old girl was found vomiting and somnolent at home and was taken to a hospital. The girl initially presented with ventricular tachycardia with broad QRS complexes which was very difficult to control. During the course a subsequent cardiogenic shock developed and despite exhaustion of all therapeutic options the fatal outcome could not be averted. The medicolegal autopsy revealed no evidence of any form of violence but the signs of medical treatment. Furthermore, no pathology of internal organs was detected. The toxicological analyses revealed a lethal intoxication with flecainide as the cause of death. The investigations of the police indicated that the girl took flecainide in suicidal intention.

PMID- 29594410 TI - 18F-FDG PET in drug-resistant epilepsy due to focal cortical dysplasia type 2: additional value of electroclinical data and coregistration with MRI. AB - PURPOSE: To assess the localizing value of 18F-FDG PET in patients operated on for drug-resistant epilepsy due to focal cortical dysplasia type 2 (FCD2). METHODS: We analysed 18F-FDG PET scans from 103 consecutive patients (52 males, 7 65 years old) with histologically proven FCD2. PET and MRI data were first reviewed by visual analysis blinded to clinical information and FCD2 location. The additional value of electroclinical data and PET/MRI coregistration was assessed by comparison with pathological results and surgical outcomes. RESULTS: Visual analysis of PET scans showed focal or regional hypometabolism corresponding to the FCD2 in 45 patients (44%), but the findings were doubtful or misleading in 37 patients and negative in 21. When considering electroclinical data, positive localization was obtained in 73 patients, and this increased to 85 (83%) after coregistration of PET and MRI data. Under the same conditions, MRI was positive in 61 patients (59%), doubtful in 15 and negative in 27. The additional value of PET was predominant in patients negative or doubtful on MRI, localizing the FCD2 in 35 patients (83%). Interobserver agreement correlated with the grade of hypometabolism: it was good in patients with mild to severe hypometabolism (82-95%), but moderate in those with subtle/doubtful hypometabolism (45%). The main factors influencing positive PET localization were the grade of hypometabolism and the size of the FCD2 (P < 0.0001). Misleading location (nine patients) was associated with a small FCD2 in the mesial frontal and central regions. Following limited cortical resection mainly located in extratemporal areas (mean follow-up 5.6 years), a seizure-free outcome was achieved in 94% of patients, including Engel's class IA in 72%. CONCLUSION: In this series, 18F-FDG PET contributed to the localization of FCD2 in 83% of patients. This high localizing value was obtained by integration of electroclinical data and PET/MRI coregistration. This approach may help improve the surgical outcome in extratemporal epilepsy, even in patients negative on MRI. PMID- 29594411 TI - Recent advances in the UltraScan SOlution MOdeller (US-SOMO) hydrodynamic and small-angle scattering data analysis and simulation suite. AB - The UltraScan SOlution MOdeller (US-SOMO) is a comprehensive, public domain, open source suite of computer programs centred on hydrodynamic modelling and small angle scattering (SAS) data analysis and simulation. We describe here the advances that have been implemented since its last official release (#3087, 2017), which are available from release #3141 for Windows, Linux and Mac operating systems. A major effort has been the transition from the legacy Qt3 cross platform software development and user interface library to the modern Qt5 release. Apart from improved graphical support, this has allowed the direct implementation of the newest, almost two-orders of magnitude faster version of the ZENO hydrodynamic computation algorithm for all operating systems. Coupled with the SoMo-generated bead models with overlaps, ZENO provides the most accurate translational friction computations from atomic-level structures available (Rocco and Byron Eur Biophys J 44:417-431, 2015a), with computational times comparable with or faster than those of other methods. In addition, it has allowed us to introduce the direct representation of each atom in a structure as a (hydrated) bead, opening interesting new modelling possibilities. In the small angle scattering (SAS) part of the suite, an indirect Fourier transform Bayesian algorithm has been implemented for the computation of the pairwise distance distribution function from SAS data. Finally, the SAS HPLC module, recently upgraded with improved baseline correction and Gaussian decomposition of not baseline-resolved peaks and with advanced statistical evaluation tools (Brookes et al. J Appl Cryst 49:1827-1841, 2016), now allows automatic top-peak frame selection and averaging. PMID- 29594412 TI - Ferritin from the haemolymph of adult ants: an extraction method for characterization and a ferromagnetic study. AB - Ferritin has been studied in many animals, plants and bacteria. The main functions of ferritin in mammals are iron concentration and stabilization, protection against oxidants and iron storage for later developmental or iron dependent activities. Although insect ferritin plays a key role in iron transport, only a few studies to date have examined its properties and function. Ferritin isolation from the haemolymph of adult Camponotus sericeiventris ants involved heating at 75 degrees C, followed by protein fractionation with 3.2 M KBr gradients and ferritin sedimentation with KBr. Protein identification was performed using high-resolution proteomics techniques. SDS-PAGE revealed three subunits with molecular weights (MW) of 26, 28 and 31 kDa. Native PAGE indicated a MW higher than 669 kDa. Proteomic analysis strongly suggested the 26 and 31 kDa bands as F2LCH and F1HCH subunits of ferritin, respectively. Ferromagnetic resonance (FMR) at 100 K showed, at low field, a characteristic broad component of the ferritin iron core, suggesting that its distribution was shifted to values greater than 3000, a higher content than in mammals. The protein yield and MW were comparable to those reported in other studies of insects. To the best of our knowledge, this is the first report on ferritin extracted from adult ants to date. These results are discussed on the basis of the protein structure-function relation of secreted insect and mammal ferritins. This purification method will allow the use of magnetic techniques, which are relevant for understanding the role of ferritin in the biomineralization of magnetic nanoparticles in insects. PMID- 29594414 TI - Aptamer-functionalized magnetic and fluorescent nanospheres for one-step sensitive detection of thrombin. AB - A one-step sandwich method is described for detecting proteins with magnetic nanospheres (MNs) and fluorescent nanospheres (FNs). Thrombin is selected as a model analyte to validate the method. Two DNA aptamers (Apt 29 and Apt 15 targeting two different exosites of thrombin) are chosen as recognition elements to modify MNs and FNs. The superparamagnetic MN-Apt 29 conjugate is used to separate and concentrate thrombin. The FN-Apt 15 conjugate encapsulates hundreds of fluorescent quantum dots and is used as reporter to provide a stable signal. Magnetic capture and fluorescence identification are performed simultaneously to form a sandwich complex (MN-Apt 29-thrombin-FN-Apt 15) for fluorescence determination (at excitation/emission wavelengths of 380/622 nm). The method is convenient, time saving, and gives a strong signal (compared to the two-step method where capture and identification are performed in two steps). The one-step method presented here is completed within 30 min and has a 3.5 ng.mL-1 (97 pM) detection limit. The method is reproducible, has an intra-assay variability of 1.5%, and an inter-assay variability of 4.9%. Other serum proteins (HSA, CEA, PSA, and AFP) do not interfere. The method was also applied to analyze serum samples. Almost the same fluorescence intensity was measured when analyzing 1% serum samples (compared to buffer samples). Graphical abstract Magnetic nanospheres with excellent superparamagnetic property and fluorescent QD-based nanospheres were prepared and used in a one-step sensitive method for detecting thrombin. The method exhibits good reproducibility, high specificity, and good selectivity. PMID- 29594413 TI - Risk factors for postoperative pneumonia in elderly patients with colorectal cancer: a sub-analysis of a large, multicenter, case-control study in Japan. AB - PURPOSE: Postoperative pneumonia affects the length of stay and mortality after surgery in elderly patients with colorectal cancer (CRC). We aimed to determine the risk factors of postoperative pneumonia in elderly patients with CRC, and to evaluate the impact of laparoscopic surgery on elderly patients with CRC. METHODS: We retrospectively investigated 1473 patients >= 80 years of age who underwent surgery for stage 0-III CRC between 2003 and 2007. Using a multivariate analysis, we determined the risk factors for pneumonia occurrence from each baseline characteristic. RESULTS: Among all included patients, 26 (1.8%) experienced postoperative pneumonia, and restrictive respiratory impairment, obstructive respiratory impairment, history of cerebrovascular events, and open surgery were determined as risk factors (odds ratio [95% confidence interval], 2.78 [1.22-6.20], 2.71 [1.22-6.30], 3.60 [1.37-8.55], and 3.57 [1.22-15.2], respectively). Furthermore, postoperative pneumonia was more frequently accompanied by increasing cumulative numbers of these risk factors (area under the receiver operating characteristic curve = 0.763). CONCLUSIONS: Laparoscopic surgery may be safely performed in elderly CRC patients, even those with respiratory impairment and a history of cerebrovascular events.

AB - Baboons are valuable models for complex human diseases due to their genetic and physiologic similarities to humans. Deep sequencing methods to characterize full length major histocompatibility complex (MHC) class I (MHC-I) alleles in different nonhuman primate populations were used to identify novel MHC-I alleles in baboons. We combined data from Illumina MiSeq sequencing and Roche/454 sequencing to characterize novel full-length MHC-I transcripts in a cohort of olive and hybrid olive/yellow baboons from the Southwest National Primate Research Center (SNPRC). We characterized 57 novel full-length alleles from 24 baboons and found limited genetic diversity at the MHC-I A locus, with significant sharing of two MHC-I A lineages between 22 out of the 24 animals characterized. These shared alleles provide the basis for development of tools such as MHC:peptide tetramers for studying cellular immune responses in this important animal model. PMID- 29594416 TI - Microwave-assisted synthesis of highly luminescent N- and S-co-doped carbon dots as a ratiometric fluorescent probe for levofloxacin. AB - Uniform N- and S-co-doped carbon dots (NSCDs) with fluorescence quantum yields of up to 64% were synthesized via a one-step microwave-assisted method. Ammonium citrate and L-cysteine act as precursors, and synthesis is completed in 2.5 min using a 750 W microwave oven to give a 62% yield. The NSCDs show bright blue fluorescence (with excitation/emission peaks at 353/426 nm) and have narrow size distribution. On exposure to levofloxacin (LEV), the emission maximum shifts to 499 nm. This effect was used to design ratiometric (2-wavelength) assays for LEV. The fluorometric method (based on measurement of the fluorescence intensity ratio at 499 and 426 nm) has a detection limit of 5.1 MUg.L-1 (3sigma/k) and a linear range that extends from 0.01 to 70 mg.L-1. The method was applied to the determination of LEV in three kinds of spiked water samples and has recoveries in the range from 98.6 to 106.8%. The fluorescent probe described here is highly selective and sensitive. Graphical Abstract Highly luminescent N- and S-co-doped carbon dots were synthesized using AC (ammonium citrate) and Cys (L-cysteine) by microwave-assisted method, and were applied to the visual and ratiometric fluorescence determination of LEV (levofloxacin). PMID- 29594417 TI - Layered vanadium(IV) disulfide nanosheets as a peroxidase-like nanozyme for colorimetric detection of glucose. AB - The authors have discovered that vanadium disulfide (VS2) nanosheets, synthesized by a hydrothermal method, exert stable peroxidase-like activity. The catalytic activity, with H2O2 as a cosubstrate, follows Michaelis-Menten kinetics and varies with temperature, pH value and H2O2 concentration. Two-dimensional VS2 sheets acting as peroxidase (POx) mimics can replace horseradish peroxidase due to their availability, robustness, and reusability. The POx-like activity of VS2 sheets was exploited to design a colorimetric glucose assay by using 3,3',5,5' tetramethylbenzidine as a substrate and by working at an analytical wavelength of 652 nm. The assay covers the 5 to 250 MUM glucose concentration range with a 1.5 MUM detection limit. It was applied to the analysis of glucose in fruit juice. In our perception, the peroxidase-like nanozyme out of the family of transition metal dichalcogenides presented here has a wide scope in that it may stimulate promising biocatalytic applications in biotechnology and analytical chemistry. Graphical abstract Layered VS2 nanosheets were prepared via hydrothermal synthesis and are shown to exert superior peroxidase-mimicking activity. Using these POx nano-mimics, a sensitive colorimetric assay for glucose was developed and applied to fruit juice analysis. This work unlocks the access of VS2 to biocatalysis and bioassays. PMID- 29594418 TI - Colorimetric determination of the activity of alkaline phosphatase based on the use of Cu(II)-modulated G-quadruplex-based DNAzymes. AB - A colorimetric detection scheme is introduced for the determination of alkaline phosphatase (ALP) activity based on Cu(II)-modulated G-quadruplex-based DNAzymes. It is exploiting the strong affinity of Cu(II) for pyrophosphate (PPi) upon which the cofactor PPi is trapped by Cu(II). Hence, the activity of the DNAzyme is inhibited. ALP catalyzes the hydrolysis of PPi, causing the release of Cu(II). DNAzyme, in turn, is activated and catalyzes the cleavage of the DNA probe substrate. The released G-rich sequence folds into the G-quadruplex, which can bind hemin and catalyze the oxidation of 2,2'-azinobis (3-ethylbenzothiozoline)-6 sulfonate (ABTS), and this leads to an increase in absorbance at 420 nm. Absorbance increases linearly with increasing ALP activity in 0.07 to 300 U.L-1 range, with a 70 mU.L-1 detection limit. The method was applied in ALP inhibition tests and to the determination of ALP activity in spiked serum samples where it gave satisfactory results. Graphical abstract A colorimetric method has been developed for the detection of alkaline phosphatase based on the use of Cu(II) modulated G-quadruplex-based DNAzymes. PMID- 29594419 TI - Highly crystalline graphitic carbon nitride quantum dots as a fluorescent probe for detection of Fe(III) via an innner filter effect. AB - Bulk g-C3N4 was transformed into water-soluble graphitic carbon nitride quantum dots (g-CNQDs) via a chemical oxidation and liquid exfoliation process. The g CNQDs possess a size distribution ranging from 1 to 5 nm (centered at 3 nm), excellent crystallinity, and are water soluble. It is found that Fe(III) ions are adsorbed on the surface of the g-CNQDs via electrostatic interaction, and that the blue fluorescence of the g-CNQDs is reduced by Fe(III) via an inner filter effect. By using the g-CNQDs as a fluorescent probe, Fe(III) can be determined at excitation/emission wavelengths of 241/368 nm in spiked natural water samples within 1 min and with good selectivity over other ions. Response is linear in the 0.2-60 MUmol.L-1 Fe(III) concentration range, and the detection limit is 23 nmol.L-1. Graphical abstract Graphitic carbon nitride quantum dots (g-CNQDs) emit blue fluorescence at an excitation wavelength of 241 nm. Fe(III) ions are quickly adsorbed on the g-CNQDs via electrostatic interaction, and fluorescence is quenched due to an inner filter effect. PMID- 29594420 TI - Colloidal crystal templated molecular imprinted polymer for the detection of 2 butoxyethanol in water contaminated by hydraulic fracturing. AB - The authors describe a molecularly imprinted polymer (MIP) that enables detection of 2-butoxyethanol (2BE), a pollutant associated with hydraulic fracturing contamination. Detection is based on a combination of a colloidal crystal templating and a molecular imprinting. The MIPs are shown to display higher binding capacity for 2BE compared to non-imprinted films (NIPs), with imprinting efficiencies of ~ 2. The tests rely on the optical effects that are displayed by the uniformly ordered porous structure of the material. The reflectance spectra of the polymer films have characteristic Bragg peaks whose location varies with the concentration of 2BE. Peaks undergo longwave red shifts up to 50 nm on exposure of the MIP to 2BE in concentrations in the range from 1 ppb to 100 ppm. This allows for quantitative estimates of the 2BE concentrations present in aqueous solutions. The material is intended for use in the early detection of contamination at hydraulic fracturing sites. Graphical abstract Molecularly imprinted polymers (MIPs) sensor with the sensing ability on reflectance spectra responding to the presence of 2-butoxyethanol (2BE) for early detection of hydraulic fracking contamination. PMID- 29594421 TI - Direct determination of the tumor marker AFP via silver nanoparticle enhanced SERS and AFP-modified gold nanoparticles as capturing substrate. AB - The authors describe a rapid and direct SERS-based immunoassay for the determination of AFP, an important marker for diagnosis of hepatocellular carcinoma. Silver nanoparticles (AgNPs; 36 nm i.d.) serve as a support to immobilize antibody and as a SERS intensifier, and AFP-modified gold nanoparticles are employed as capturing substrate. Direct and quantitative detection of AFP is accomplished with a limit detection as low as 5 ng.mL-1. Compared to assays based on the use of metal nanoparticles, the use of gold silver nanoparticle heterodimers as an active SERS substrate can save costs because only a single antibody is required. Moreover, the high selectivity and good linear relationship of detecting AFP in fetal bovine serum indicates its potential applicability for the direct analysis of clinical samples. Graphical abstract Direct and quantitative determination of AFP antigen utilizing SERS has been was successfully presented and applied to detect alpha fetoprotein antigen in fetal bovine serum with detection limit of 2 ng*mL-1.

AB - A nanoporous platinum-yttrium alloy (NP-PtY) was fabricated by dealloying ribbons of a PtYAl alloy. Owing to the high porosity and the synergistic effect of Y in the Pt backbone, the NP-PtY exhibits superior structural stability, reproducibility and electrocatalytic activity. An electrochemical sensor was developed for the highly sensitive and selective detection of dopamine (DA) based on the use of a glassy carbon electrode modified with NP-PtY alloy and graphene. The sensor, best operated at 0.16 V vs. SCE, has a linear range covering the 0.9 to 82 MUM concentration range, a 0.36 MUM detection limit (at S/N = 3), and good selectivity over tyramine, tryptamine, phenethylamine, uric acid, and ascorbic acid. It gave satisfactory results in the determination of DA in spiked samples of urine. Graphical abstract Nanoporous platinum-yttrium alloy (NP-PtY) was fabricated by means of a one-step dealloying process. A glassy carbon electrode modified with the NP-PtY and graphene nanocomposite exhibits a wide linear range and a low detection limit towards dopamine. The sensor has remarkable reproducibility, stability and selectivity. PMID- 29594425 TI - A Journey Through Innovations: Remembering Hardships and Compassion.

AB - Molecular epidemiological analysis of cryptosporidiosis in Middle Eastern countries suggests that small ruminants could play a major role in the transmission of Cryptosporidium spp. to humans, with a dominance of Cryptosporidium parvum, especially its IId subtypes. However, little information is available on the epidemiology and risk factors of cryptosporidiosis as well the distribution of Cryptosporidium species/genotypes and subtypes in small ruminants in this area, including Kuwait. In the present study, 47 farms from several areas in Kuwait were visited once during October 2014 to September 2015 to collect data on risk factors associated with Cryptosporidium infection. Fecal samples from 334 sheep and 222 goats were examined for Cryptosporidium oocysts by Ziehl-Neelsen staining (ZN) and antigens by enzymatic immunoassay (EIA). The Cryptosporidium prevalence was higher when samples were examined by EIA than ZN (11.4 and 7.2% in sheep and goats by EIA, compared with 4.2 and 3.6% by ZN, respectively). Young age (less than 3 months) and closed housing system are risk factors of Cryptosporidium infection. A correlation between fecal consistency and the occurrence of Cryptosporidium spp. was observed; non-formed fecal samples were often found positive. Molecular characterization of 30 ovine and caprine samples using PCR-RFLP analysis of the small subunit rRNA gene revealed the presence of C. parvum in 23 samples, Cryptosporidium ubiquitum in five samples, and Cryptosporidium xiaoi in two samples. Sequence analysis of C. parvum at the 60 KDa glycoprotein gene locus identified two subtypes, IIaA15G2R1 and IIdA20G1, with the latter being more common (in 2 and 20 successfully subtyped samples, respectively). Only one subtype of C. ubiquitum (XIIa) was recorded. Cryptosporidiosis in small ruminants apparently poses public health problem in Kuwait.

AB - The hypothesis of hot volcanic organic stream as the most probable and geologically plausible environment for abiogenic polycondensation is proposed. The primary synthesis of organic compounds is considered as result of an explosive volcanic (perhaps, meteorite-induced) eruption. The eruption was accompanied by a shock wave propagating in the primeval atmosphere and resulting in the formation of hot cloud of simple organic compounds-aldehydes, alcohols, amines, amino alcohols, nitriles, and amino acids-products, which are usually obtained under the artificial conditions in the spark-discharge experiments. The subsequent cooling of the organic cloud resulted in a gradual condensation and a serial precipitation of organic compounds (in order of decreasing boiling point values) into the liquid phase forming a hot, viscous and muddy organic stream (named "lithorheos"). That stream-even if the time of its existence was short-is considered here as a geologically plausible environment for abiogenic polycondensation. The substances successively prevailing in such a stream were cyanamide, acetamide, formamide, glycolonitrile, acetonitrile. An important role was played by mineral (especially, phosphate-containing) grains (named "lithosomes"), whose surface was modified with heterocyclic nitrogen compounds synthesized in the course of eruption. When such grains got into hot organic streams, their surface catalytic centers (named "lithozymes") played a decisive role in the emergence, facilitation and maintenance of prebiotic reactions and key processes characteristic of living systems. Owing to its cascade structure, the stream was a factor underlying the formation of mineral-polymeric aggregates (named "lithocytes") in the small natural streambed cavities (dimples)-as well as a factor of their further spread within larger geological locations which played a role of chemo-ecological niches. All three main stages of prebiotic evolution (primary organic synthesis, polycondensation, and formation of proto-cellular structures) are combined within a common dynamic geological process. We suppose macromolecular evolution had an extremely fast, "flash" start: the period from volcanic eruption to formation of lithocyte "populations" took not million years but just several tens of minutes. The scenario proposed can be verified experimentally with a three-module setup working with principles of dynamic (flow) chemistry in its core element. PMID- 29594427 TI - Fluorescence turn-on detection of target sequence DNA based on silicon nanodot mediated quenching. AB - We have developed a new enzyme-free method for target sequence DNA detection based on the dynamic quenching of fluorescent silicon nanodots (SiNDs) toward Cy5 tagged DNA probe. Fascinatingly, the water-soluble SiNDs can quench the fluorescence of cyanine (Cy5) in Cy5-tagged DNA probe in homogeneous solution, and the fluorescence of Cy5-tagged DNA probe can be restored in the presence of target sequence DNA (the synthetic target miRNA-27a). Based on this phenomenon, a SiND-featured fluorescent sensor has been constructed for "turn-on" detection of the synthetic target miRNA-27a for the first time. This newly developed approach possesses the merits of low cost, simple design, and convenient operation since no enzymatic reaction, toxic reagents, or separation procedures are involved. The established method achieves a detection limit of 0.16 nM, and the relative standard deviation of this method is 9% (1 nM, n = 5). The linear range is 0.5-20 nM, and the recoveries in spiked human fluids are in the range of 90-122%. This protocol provides a new tactic in the development of the nonenzymic miRNA biosensors and opens a promising avenue for early diagnosis of miRNA-associated disease.

AB - The substance group of very volatile organic compounds (VVOCs) is moving into the focus of indoor air analysis, facing ongoing regulations at international and European levels targeting on indoor air quality and human health. However, there exists at present no validated analysis for the identification and quantification of VVOCs in indoor air. Therefore, the present study targeted on the development of an analytical method in order to sample the maximum possible quantity of VVOCs in indoor air on solid sorbents with subsequent analysis by thermal desorption and coupled gas chromatography/mass spectrometry (TDS-GC/MS). For this purpose, it was necessary to investigate the performance of available sorbents and to optimize the parameters of GC/MS analysis. Stainless steel tubes filled with Carbograph 5TD were applied successfully for low-volume sampling (2-4 l) with minimal breakthrough (< 1%). With the developed method, VVOCs between C3 and C6 of different volatility and polarity can be detected even in trace quantities with low limits of quantitation (LOQ; 1-3 MUg m-3). Limitations occur for low molecular weight compounds <=C3, especially for polar substances, such as carboxylic acids and for some aldehydes and alcohols. Consequently, established methods for the quantification of these compounds in indoor air cannot be fully substituted yet. At least three different analytical techniques are needed to cover the large spectrum of relevant VVOCs in indoor air. In addition, unexpected reaction products might occur and need to be taken into account to avoid misinterpretation of chromatographic signals. Graphical abstract Solid sorbent sampling of VVOCs (C3-C6) in indoor air with subsequent TDS-GC/MS analysis. PMID- 29594430 TI - Non-targeted analysis of unexpected food contaminants using LC-HRMS. AB - A non-target analysis method for unexpected contaminants in food is described. Many current methods referred to as "non-target" are capable of detecting hundreds or even thousands of contaminants. However, they will typically still miss all other possible contaminants. Instead, a metabolomics approach might be used to obtain "true non-target" analysis. In the present work, such a method was optimized for improved detection capability at low concentrations. The method was evaluated using 19 chemically diverse model compounds spiked into milk samples to mimic unknown contamination. Other milk samples were used as reference samples. All samples were analyzed with UHPLC-TOF-MS (ultra-high-performance liquid chromatography time-of-flight mass spectrometry), using reversed-phase chromatography and electrospray ionization in positive mode. Data evaluation was performed by the software TracMass 2. No target lists of specific compounds were used to search for the contaminants. Instead, the software was used to sort out all features only occurring in the spiked sample data, i.e., the workflow resembled a metabolomics approach. Procedures for chemical identification of peaks were outside the scope of the study. Method, study design, and settings in the software were optimized to minimize manual evaluation and faulty or irrelevant hits and to maximize hit rate of the spiked compounds. A practical detection limit was established at 25 MUg/kg. At this concentration, most compounds (17 out of 19) were detected as intact precursor ions, as fragments or as adducts. Only 2 irrelevant hits, probably natural compounds, were obtained. Limitations and possible practical use of the approach are discussed. PMID- 29594429 TI - Highly sensitive detection of a small molecule by a paired labels recognition system based lateral flow assay. AB - Small molecules are difficult to detect by conventional gold lateral flow assay (GLFA) sensitively because the test system must satisfy the conflict requirements between enough signal intensity and limited antibody (Ab) amount. In this work, a paired labels recognition (PLR)-based biosensor was designed by utilizing the specific binding of Ab and secondary antibody (anti-Ab) to enhance signal intensity and reduce antibody amount applied in small molecule detection. The PLR amplification system is fabricated by self-assembling the common detection probe, Au-labeled Ab (Au-Ab), and the signal booster, Au-labeled anti-Ab (Au-anti-Ab). Benefiting from this, a powerful network structure can be generated to accumulate numerous gold nanoparticles (GNPs) and thus significantly strengthen the signal intensity of detection. Therefore, a lower Ab amount will be applied to offer adequate signal strength, and further, the limit of detection will be obviously downregulated due to the more effective competition reaction. Using furazolidone (FZD) as a model analyte, we achieve a detection limit of as low as 1 ng mL-1, which was at least fivefold improved over that of the traditional GLFA. Furthermore, the practicality of this strategy was certificated in five different food samples. Graphical abstract A paired labels recognition (PLR) amplification system is fabricated by self-assembling the common detection probe, Au-labeled Ab (Au-Ab), and the signal booster, Au-labeled anti-Ab (Au-anti-Ab). In this novel strategy, owing to the recognition of both Ab and anti-Ab labeled on gold nanoparticles (GNPs), a powerful network structure can be generated to accumulate numerous GNPs and thus significantly strengthen the signal intensity of detection. PMID- 29594431 TI - Probiotics for Plants? Growth Promotion by the Entomopathogenic Fungus Beauveria bassiana Depends on Nutrient Availability. AB - Cultivation of crops requires nutrient supplements which are costly and impact the environment. Furthermore, global demands for increased crop production call for sustainable solutions to increase yield and utilize resources such as nutrients more effectively. Some entomopathogenic fungi are able to promote plant growth, but studies over such effects have been conducted under optimal conditions where nutrients are abundantly available. We studied the effects of Beauveria bassiana (strain GHA) seed treatment on the growth of maize (Zea mays) at high and low nutrient conditions during 6 weeks in greenhouse. As expected, B. bassiana seed treatment increased plant growth, but only at high nutrient conditions. In contrast, the seed treatment did not benefit plant growth at low nutrient conditions where the fungus potentially constituted a sink and tended to reduce plant growth. The occurrence of endophytic B. bassiana in experimental plant tissues was evaluated by PCR after 6 weeks, but B. bassiana was not documented in any of the above-ground plant tissues indicating that the fungus plant interaction was independent of endophytic establishment. Our results suggest that B. bassiana seed treatment could be used as a growth promoter of maize when nutrients are abundantly available, while the fungus does not provide any growth benefits when nutrients are scarce.

AB - : Congenital nephrogenic diabetes insipidus (CNDI) is characterized by the reduced ability of renal collecting duct cells to reabsorb water in response to the antidiuretic effect of vasopressin. Chronic polyuria and polydipsia are the hallmarks of the disease. Approximately 90% of all patients with CNDI have X linked inherited disease caused by variants in the arginine vasopressin receptor 2 (AVPR2) gene. We present genetic findings in 34 individuals from 19 kindreds including one or more family members with CNDI. Coding regions of AVPR2 were sequenced bi-directionally. We identified eight novel disease-causing variants in AVPR2, p.Arg68Alafs*124, p.Ser171Arg, p.Gln174Pro, p.Trp200Arg, p.Gly201Cys, p.Gly220Arg, p.Val226Glu, and p.Gln291Pro in nine kindreds. In all three families with more than one affected individual, the novel variants segregated with the disease. We also identified eight recurrent disease-causing variants, p.Val88Met, p.Leu111Valfs*80, p.Arg113Trp, p.Tyr124*, p.Ser167Leu, p.Thr207Asn, p.Arg247Alafs*12, and p.Arg337* in ten kindreds. Our findings contribute to the growing list of AVPR2 variants causing X-linked CNDI. CONCLUSION: Being a rapid diagnostic tool for CNDI, direct sequencing of AVPR2 should be encouraged in newborns with familial predisposition to CNDI. What is Known: * Disease-causing variants in AVPR2 cause X-linked congenital nephrogenic diabetes insipidus (CNDI). * DNA sequencing of AVPR2 is rapid, facilitates differential diagnosis, early intervention, and genetic diagnosis thus reducing morbidity in CNDI. What is New: * We identified eight novel disease-causing variants in AVPR2: p.Arg68Alafs*124, p.Ser171Arg, p.Gln174Pro, p.Trp200Arg, p.Gly201Cys, p.Gly220Arg, p.Val226Glu, and p.Gln291Pro, thereby adding to the growing list of AVPR2 disease-causing variants and emphasizing the importance of genetic testing in CNDI. PMID- 29594433 TI - The Distributions of Voltage-Gated K+ current Subtypes in Different Cell Sizes from Adult Mouse Dorsal Root Ganglia. AB - Voltage-gated K+ (KV) currents play a crucial role in regulating pain by controlling neuronal excitability, and are divided into transient A-type currents (IA) and delayed rectifier currents (IK). The dorsal root ganglion (DRG) neurons are heterogeneous and the subtypes of KV currents display different levels in distinct cell sizes. To observe correlations of the subtypes of KV currents with DRG cell sizes, KV currents were recorded by whole-cell patch clamp in freshly isolated mouse DRG neurons. Results showed that IA occupied a high proportion in KV currents in medium- and large-diameter DRG neurons, whereas IK possessed a larger proportion of KV currents in small-diameter DRG neurons. A lower correlation was found between the proportion of IA or IK in KV currents and cell sizes. These data suggest that IA channels are mainly expressed in medium and large cells and IK channels are predominantly expressed in small cells. PMID- 29594435 TI - Higher serum carotenoids associated with improvement of non-alcoholic fatty liver disease in adults: a prospective study. AB - PURPOSE: Previous studies have suggested that serum carotenoids might be inversely associated with non-alcoholic fatty liver disease (NAFLD), but little data came from longitudinal studies. We prospectively examined the associations between serum-carotenoid levels and NAFLD severity and the intermediary effects of retinol-binding protein 4 (RBP4), HOMA insulin-resistance index (HOMA-IR), body mass index (BMI), and serum triglycerides in middle-aged and elderly Chinese adults. METHODS: This prospective study included 3336 Chinese adults (40-75 years). We assessed serum concentrations of carotenoids at baseline and determined serum RBP4, triglycerides, and HOMA-IR levels at year 3. Abdominal ultrasonography was conducted to assess the presence and degree of NAFLD at years 3 and 6. RESULTS: The 2687 subjects who completed both NAFLD tests were classified into stable, improved and progressed groups according to changes in the degree of NAFLD between two visits. Analyses of covariance showed that ln transformed serum concentrations of alpha-carotene, beta-cryptoxanthin, beta carotene, lycopene, lutein/zeaxanthin, and total carotenoids were positively associated with NAFLD improvement (all p-trend < 0.05). After multivariable adjustment, mean differences in serum carotenoids were higher by 29.6% (beta carotene), 18.2% (alpha-carotene), 15.6% (beta-cryptoxanthin), 11.5% (lycopene), 8.9% (lutein/zeaxanthin), and 16.6% (total carotenoids) in the improved vs. progressed subjects. Path analyses indicated the carotenoid-NAFLD association was mediated by lowering serum RBP4, triglycerides, HOMA-IR, and BMI, which were positively associated with the prevalence and progression of NAFLD. CONCLUSIONS: In middle-aged and elderly adults, higher serum-carotenoid concentrations were favorably associated with NAFLD improvement, mediated by reducing serum RBP4, triglycerides, HOMA-IR, and BMI.

PMID- 29594436 TI - A palladium-platinum bimetal nanodendritic melamine network for signal amplification in voltammetric sensing of DNA. AB - A sandwich-type electrochemical DNA sensor is described for the detection of oligonucleotides typical for MECP2 gene mutations. Palladium nanoparticles (PdNPs) and platinum nanoparticles (PtNPs) were used to synthesize flower-like PdPt nanodendrites (NDs) by a one-pot method. The PdPt NDs possess a high specific surface area and excellent catalytic capabilities. They served as the carrier for the signal DNA probe (SP) and simultaneously catalyze the reduction of hydrogen peroxide (H2O2). The PdPt NDs were modified with melamine, and this results in the formation of a PdPt-melamine network through stable interactions between the PdPt NDs and the three amino groups of each melamine molecule. The network exhibits excellent catalytic ability in enhancing the current signal response in the voltammetric detection of MECP2 gene mutation, best measured at 0.4 V vs. SCE and using H2O2 as the electrochemical probe. In addition, gold nanoflowers were electrodeposited on the electrode interface in order to accelerate electron transfer and to capture the capture probe. The sensor is stable and can detect MECP2 gene mutations in the 1 fmol.L-1 to 1 nmol.L-1 concentration range, with a 0.33 fmol.L-1 lower detection limit at an S/N ratio of 3. Graphical abstract Schematic presentation of electrodes for the determination of the X-linked gene methyl-CpG-binding protein 2 (MECP2). The sensor is based on the electrooxidation of added H2O2 by using the melamine modified palladium platinum bimetal nanodendrites as network signal amplification strategy. This versatile platform expands studies on the detection of monogenic disease. PMID- 29594437 TI - [Correction to: Endocrine paraneoplastic syndromes].

AB - Dysplastic megalencephaly, also known as bilateral hemimegalencephaly, is a rare cerebral malformation characterized by bilateral cerebral hemisphere overgrowth and extensive malformation of cortical development. Affected patients present clinically with intractable seizures, severe neurological impairment and global developmental delay. There is a small body of literature reporting megalencephaly's association with neonatal high-output cardiac failure and a lack of literature describing prenatal findings. We report a case of dysplastic megalencephaly presenting with progressive high-output cardiac failure during fetal life. Prenatal and postnatal imaging findings as well as neonatal course are described. A companion case with similar imaging findings will help illustrate the prenatal imaging characteristics of this association. Knowledge of this potential complication related to dysplastic megalencephaly may help guide parental counseling and obstetric management.

AB - Heart failure and kidney dysfunction are common comorbidities with overlapping and synergizing mechanisms. Coincidence of both pathologies aggravates disease progression rates, symptoms, and outcomes. The treatment of patients with advanced renal insufficiency is faced with limited evidence for therapies that are standard of care in patients with normal and moderate kidney failure, frequent deterioration of kidney function during therapy, and onset of hyperkalemia, which pose challenges for clinical care, requiring intensified physician-patient contacts. A special challenge is the so-called diuretic resistance, which may require extracorporeal drainage. PMID- 29594440 TI - Clinical safety of 3-T brain magnetic resonance imaging in newborns. AB - BACKGROUND: The effects and potential hazards of brain magnetic resonance imaging (MRI) at 3 T in newborns are debated. OBJECTIVE: Assess the impact of 3-T MRI in newborns on body temperature and physiological parameters. MATERIAL AND METHODS: Forty-nine newborns, born preterm and at term, underwent 3-T brain MRI at term corrected age. Rectal and skin temperature, oxygen saturation and heart rate were recorded before, during and after the scan. RESULTS: A statistically significant increase in skin temperature of 0.6 degrees C was observed at the end of the MRI scan (P<0.01). There was no significant changes in rectal temperature, heart rate or oxygen saturation. CONCLUSION: Core temperature, heart rate and oxygen saturation in newborns were not affected by 3-T brain MR scanning. PMID- 29594441 TI - Enhancement of lateral flow immunoassay by alkaline phosphatase: a simple and highly sensitive test for potato virus X. AB - Alkaline phosphatase (ALP) was used as an amplification tool in lateral flow immunoassay (LFIA). Potato virus X (PVX) was selected as a target analyte because of its high economic importance. Two conjugates of gold nanoparticles were applied, one with mouse monoclonal antibody against PVX and one with ALP-labeled antibody against mouse IgG. They were immobilized to two fiberglass membranes on the test strip for use in LFIA. After exposure to the sample, a substrate for ALP (5-bromo-4-chloro-3-indolyl phosphate/nitro blue tetrazolium) was dropped on the test strip. The insoluble dark-violet diformazan produced by ALP precipitated on the membrane and significantly increased the color intensity of the control and test zones. The limit of detection (0.3 ng mL-1) was 27 times lower than that of conventional LFIA for both buffer and potato leaf extracts. The ALP-enhanced LFIA does not require additional preparation procedures or washing steps and may be used by nontrained persons in resource-limited conditions. The new method of enhancement is highly promising and may lead to application for routine LFIA in different areas. Graphical abstract Two gold nanoparticles (GNP) conjugates were used - the first with monoclonal antibodies (mAb) (GNP-mAb); the second - alkaline phosphatase-labeled antibody against mAb (GNP-anti-mAb-ALP). The immuno complexes are captured by the polyclonal antibodies (pAb) in the test zone. Addition of the substrate solution (BCIP/NBT) results in the accumulation of the insoluble colored product and in a significance increase in color intensity. PMID- 29594442 TI - Determination of bromate via the chemiluminescence generated in the sulfite and carbon quantum dot system. AB - The authors describe a chemiluminescence (CL)-based assay for the determination of bromate. The method is based on the use of a solution of carbon quantum dots (CQDs) and sulfite. Strong CL (peak at 490 nm) is observed when bromate is injected into the solution. The CL increases linearly in the 0.3 to 10 MUmol L-1 bromate concentration range, giving a 0.1 MUmol L-1 limit of detection (at an S/N ratio of 3). A possible CL mechanism is suggested that involves a redox reaction between the CQDs, bromate and sulfite in the acidic medium. This leads to the formation of hole-injected and electron-injected CQDs. Radiative recombination of oxidant-injected holes and electrons in the CQDs accounts for the occurrence of CL. This mechanism contradicts the previous assumption that the transfer of energy occurs from SO2* to the CQDs. Although nitrite may interfere in the determination of bromate, its effect can be eliminated by adding sulfamic acid. The assay is sensitive and represents a new tool for the determination of bromate, which is a carcinogen. Graphical abstract Under acidic condition, carbon quantum dots (CQDs) can react with sulfite and bromate transforming to hole injected CQDs (CQDs*-) and electron-injected CQDs (CQDs*+), respectively. Thereafter, strong chemiluminescence (490 nm) aroused from the radiative electron hole annihilation between CQDs*- and CQDs*+.

AB - Fluorescent iridium nanoclusters (IrNCs) consisting of up to 7 Ir atoms were prepared by heating IrCl3 in N,N-dimethylformamide. No other reagents are required. High resolution transmission electron microscopy (HRTEM) shows the IrNCs to be monodispersed with an average size of 0.9 +/- 0.2 nm. They are well soluble in polar solvents and stable in these solvents for at least 6 months. Under photoexcitation with 365 nm light, they emit strong bluish green fluorescence with peaks that depend on the excitation wavelength and range from 530 to 650 nm. The fluorescence lifetime typically is 2.2 ns and the quantum yield is 8.3%. Fluorescence is quenched by Cr(VI) ion (chromate), and the emission peak is gradually red-shifted. According to the absorbance spectra of IrNCs in the presence and absence of Cr(VI) and Stern-Volmer quenching behavior study, static quenching is involved. Based on these findings, a selective assay was developed for the determination of Cr(VI). It has a linear response in the 0.1 to 100 MUM chromate concentration range and a 25 nM detection limit. Graphic abstract Fluorescent iridium nanoclusters (IrNCs), consisting of up to 7 Ir atoms, were prepared in N,N-dimethylformamide (DMF) solution without using any other reagents. Their fluorescence is statically quenched by Cr(VI). PMID- 29594444 TI - Epidemiology of hip fractures : Systematic literature review of German data and an overview of the international literature. AB - BACKGROUND: Hip fractures are regarded as a worldwide epidemic and a major public health concern. Changing risk factors, local differences and temporal trends contribute to the particular epidemiology of hip fractures. This overview gives a comprehensive insight into the epidemiology of hip fractures and reviews where German data have contributed to the literature. METHODS: The review of the epidemiology of hip fractures in Germany is based on a systematic literature search in PubMed. Information about the global epidemiology of hip fractures was provided by a selective literature review focusing on specific aspects of the epidemiology of hip fractures. RESULTS: Hip fracture rates vary more than 100 fold between different countries. In most high-income countries, a rise in age standardized hip fracture rates was observed until the 1980s and 1990s and a decrease thereafter. Such a decrease has not been observed for Germany so far. Many factors, diseases and drugs have been found to be associated with hip fractures and there is some evidence that fracture risk in later life is already programmed during fetal life and early childhood. Of the hip fracture burden 50% occur in people with disability and in need of care. In nursing homes approximately 4 fractures can be expected in 100 women per year. In people with intellectual or developmental disabilities comparable risks of hip fracture occur 10-40 years earlier than in the general population. Incidence of disability, institutionalization and death are frequent consequences of hip fractures. CONCLUSION: The epidemiology of hip fractures is characterized by a high burden of disease, local differences, temporal trends, well-defined high-risk populations and many established risk factors. PMID- 29594445 TI - The prognostic implications of primary tumor location on recurrence in early stage colorectal cancer with no associated risk factors. AB - PURPOSE: Recently, several reports have suggested that tumor location serves as a prognostic biomarker in advanced colorectal cancer. However, the prognostic implication of tumor location in patients with early-stage colorectal cancer remains unclear. This study was aimed to examine the prognostic implication of tumor location in patients with early-stage colorectal cancer. METHODS: Patients with stage I and low-risk stage II colorectal cancer, treated with radical surgery in a hospital setting between May 2003 and September 2014, were retrospectively reviewed. Patients who underwent (neo) adjuvant chemotherapy and/or radiotherapy and whose microsatellite instability (MSI) status was lacked were excluded. Distal colon cancer was defined as tumors located from the splenic flexure colon to the sigmoid colon. RESULTS: A total of 712 patients were included in this study. Of these patients, 23 (3.2%) had a recurrence at a median follow-up time of 46 months. The tumor recurrence rate was significantly low in patients with proximal colon cancer. In the multivariate analysis, tumors located in the distal colon or rectum (distal colon, hazard ratio [HR] 9.213, P = 0.035; rectum, HR 15.366, P = 0.009) and T3 tumors (HR 4.590, P = 0.017) were related to tumor recurrence. A higher prevalence of tumor recurrence was found in patients with two recurrence factors than those who had only one factor or none (P < 0.001). CONCLUSIONS: Tumor location, as well as T stage, had prognostic implication in patients with early-stage colorectal cancer. Validation of our results is needed in a large cohort with genetic characterization. PMID- 29594446 TI - Comprehensive Evaluation of Soil Near Uranium Tailings, Beishan City, China. AB - To evaluate the impact of uranium tailings on soil composition and soil microbial, six soil samples at different distance from the uranium tailings (Beishan City, China) were collected for further analysis. Concentrations of radionuclides (238U and 232Th), heavy metals (Mn, Cd, Cr, Ni, Zn, and Pb) and organochlorine pesticide were determined by ICP-MS and GC, they were significantly higher than those of the control. And the Average Well Color Development as well as the Shannon, the Evenness, and the Simpson index were calculated to evaluate the soil microbial diversity. The carbon utilization model of soil microbial community was also analyzed by Biolog-eco. All results indicated that uranium tailings leaded to excessive radionuclides and heavy metals, and decreased the diversity of the soil microbial community. Our study will provide a valuable basis for soil quality evaluation around uranium tailing repositories and lay a foundation for the management and recovery of uranium tailings. PMID- 29594447 TI - A conventional chemical reaction for use in an unconventional assay: A colorimetric immunoassay for aflatoxin B1 by using enzyme-responsive just-in-time generation of a MnO2 based nanocatalyst. AB - The authors describe a colorimetric immunoassay for the model nalyte aflatoxin B1 (AFB1). It is based on the just-in-time generation of an MnO2 nanocatalyst. Unlike previously developed immunoassay, the chromogenic reaction relies on the just-in-time formation of an oxidase mimic without the aid of the substrate. Potassium permanganate (KMnO4) is converted into manganese dioxide (MnO2) which acts as an oxidase mimic that catalyzes the oxidation 3,3',5,5' tetramethylbenzidine (TMB) by oxygen to give a blue colored product. In the presence of ascorbic acid (AA), KMnO4 is reduced to Mn(II) ions. This results in a decrease in the amount of MnO2 nanocatalyst. Hence, the oxidation of TMB does not take place. By adding ascorbate oxidase, AA is converted into dehydroascorbic acid which cannot reduce KMnO4. Based on these observations, a colorimetric competitive enzyme immunoassay was developed where ascorbate oxidase and gold nanoparticle-labeled antibody against AFB1 and magnetic beads carrying bovine serum albumin conjugated to AFB1 are used for the determination of AFB1. In presence of AFB1, it will compete with the BSA-conjugated AFB1 (on the magnetic beads) for the labeled antibody against AFB1 on the gold nanoparticles. This makes the amount of ascorbate oxidase/anti-AFB1 antibody-labeled gold nanoparticles, which conjugated on magnetic beads, reduce, and resulted in an increase of ascorbic acid. Under optimal conditions, the absorbance (measured at 652 nm) decreases with increasing AFB1 concentrations in the range from 0.1 to 100 ng mL-1, with a 0.1 ng mL-1 detection limit (at the 3Sblank level). The accuracy of the assay was validated by analyzing spiked peanut samples. The results matched well with those obtained with a commercial ELISA kit. Conceivably, the method is not limited to aflatoxins but has a wide scope in that it may be applied to many other analytes for which respective antibodies are available. Graphical abstract Schematic illustration of ascorbate oxidase (AOx) mediated potassium permanganate (KMnO4)-responsive ascorbic acid (AA) for visual colorimetric immunoassay of aflatoxin B1 (AFB1) by coupling with hydrolytic reaction of AOx toward AA and the KMnO4-Mn(II)-TMB system [note: 3,3',5,5' tetramethylbenzidine: TMB].

AB - The authors describe a sensor based on the deposition of the binary oxide SnO2 Mn3O4 between copper electrodes fixed on a glass substrate. The impedance of the sensor is shown to strongly depend on relative humidity (RH) and mechanical pressure. A silicone adhesive was added to the binary oxide nanomaterials and investigated with respect to its effect on the sensing performance. The impedance of the material decreases by a factor of 54.7 with increasing RH in the range of 10-90% in pristine SnO2-Mn3O4 nanorods, but 29.6 times in SnO2-Mn3O4 nanocomposites. Capacitance increases 390 times in pristine SnO2-Mn3O4 and 26.6 times in SnO2-Mn3O4 silicone nanocomposite at 100 Hz on going from 10 to 90% RH. Similarly, the impedance of the sensor also depends on mechanical pressure. The impedance of the material decreases by 80% on applying a mechanical pressure of 11.0 kN.m-2, while capacitance increases by 70% at the same pressure. Graphical abstract A multimodal sensor was fabricated using SnO2-Mn3O4 mixed oxide and its nanocomposite with silicon adhesive. The impedance of the material decreases while capacitance increases much more with increase in relative humidity and applying a mechanical pressure in SnO2-Mn3O4 mixed oxide as compared to SnO2 Mn3O4 nanocomposite.

AB - The authors describe a sensitive fluorometric method for the determination of the activity of alkaline phosphatase (ALP). It is based on the use of a composite prepared consisting of flower-like cobalt oxyhydroxide (CoOOH) and copper nanoclusters (CuNCs). On formation of the CuNC-CoOOH aggregates, the fluorescence of the CuNCs is quenched by the CoOOH sheets. If, however, the CoOOH sheets are reduced to Co(II) ions in the presence of ascorbic acid (AA), fluorescence recovers. AA is formed in-situ by hydrolysis of the substrate ascorbic acid 2 phosphate (AA2P) as catalyzed by ALP. Thus, the ALP activity can be detected indirectly by kinetic monitoring of the increase in fluorescence, best at excitation/emission wavelengths of 335/410 nm. The assay allows ALP to be determined in 0.5 to 150 mU.mL-1 activity range and with a 0.1 mU.mL-1 detection limit. The method was successfully applied to the determination of ALP activity in (spiked) human serum samples. The assay has attractive features in being of the off-on type and immune against false positive results. Graphical Abstract A fluorescent bioassay is reported for the determination of the activity of alkaline phosphatase (ALP). It is exploiting the ascorbic acid (AA)-induced decomposition of nanoclusters composed of flower-like cobalt oxyhydroxide and copper nanoclusters. ALP catalyzes hydrolysis of ascorbic acid 2-phosphate (AA2P) and dephosphorylation to form AA.

AB - The authors describe a new coating for use in electrochemically controlled in tube solid phase microextraction (EC-IT-SPME). It consists of a nanocomposite that was prepared from polypyrrole and deep eutectic solvent (DES) by electrochemical deposition on the inner walls of a stainless steel capillary that serves as a working electrode. The hypertension drug losartan acts as an acidic model analyte. The extraction efficiency, mechanical stability, chemical stability and lifetime of the coating were investigated. It is found to be quite stable in relatively acidic and basic media and to be re-usable >450 times without decrease in extraction efficiency. Its extraction capability in comparison to the commercial polypyrrole coating is better by a factor of 1.5. The coated steel capillary was used as the anode (anion-exchanger), and a platinum electrode was used as the cathode. By passing a sample solution through the electrode, losartan can be extracted by applying a positive potential to the flow. In the next step, losartan is electrochemically desorbed and subjected to HPLC analysis with UV detection. Under optimal conditions, losartan can be quantified with limits of detection that range from 50 to 500 ng L-1 depending on the sample matrix. Response is linear in the 0.1-500 MUg L-1 concentration range. The inter- and intra-assay precisions (RSDs; in %, for n = 3) are in the range from 2.4-4.6% and from 1.9-3.9%, respectively. Graphical abstract Schematic of the preparation of a nano-structured polypyrrole-deep eutectic solvent nanocomposite coating placed on the inner surface of a stainless steel capillary and used for electrochemically controlled in-tube solid phase microextraction of losartan from biological samples.

AB - Nanoparticle assisted laser desorption/ionization mass spectrometry (NPs-ALDI-MS) shows remarkable characteristics and has a promising future in terms of real sample analysis. The incorporation of NPs can advance several methods including surface assisted LDI-MS, and surface enhanced LDI-MS. These methods have advanced the detection of many thermally labile and nonvolatile biomolecules. Nanoparticles circumvent the drawbacks of conventional organic matrices for the analysis of small molecules. In most cases, NPs offer a clear background without interfering peaks, absence of fragmentation of thermally labile molecules, and allow the ionization of species with weak noncovalent interactions. Furthermore, an enhancement in sensitivity and selectivity can be achieved. NPs enable straightforward analysis of target species in a complex sample. This review (with 239 refs.) covers the progress made in laser-based mass spectrometry in combination with the use of metallic NPs (such as AuNPs, AgNPs, PtNPs, and PdNPs), NPs consisting of oxides and chalcogenides, silicon-based NPs, carbon based nanomaterials, quantum dots, and metal-organic frameworks. Graphical abstract An overview is given on nanomaterials for use in surface-assisted laser desorption/ionization mass spectrometry of small molecules.

AB - An aptamer-based method is described for electrochemical determination of lysozyme. A glassy carbon electrode was modified with a nanocomposite composed of multi-walled carbon nanotubes, poly(diallyl dimethyl ammonium chloride), and carbon quantum dots. The composition of the nanocomposite (MWCNT/PDDA/CQD) warrants good electrical conductivity and a high surface-to-volume ratio. The lysozyme-binding aptamers were immobilized on the nanocomposite via covalent coupling between the amino groups of the aptamer and the carboxy groups of the nanocomposite. The modified electrode was characterized by electrochemical impedance spectroscopy, cyclic voltammetry and differential pulse voltammetry. The use of this nanocomposite results in a considerable enhancement of the electrochemical signal and contributes to improving sensitivity. Hexacyanoferrate was used as an electrochemical probe to study the dependence of the peak current on lysozyme concentration. In the presence of lysozyme, the interaction of lysozyme with immobilized aptamer results in a decrease of the peak current, best measured at +0.15 V vs. Ag/AgCl. A plot of peak current changes versus the logarithm of the lysozyme concentration is linear in the 50 fmol L-1 to 10 nmol L 1 concentration range, with a 12.9 fmol L-1 detection limit (at an S/N ratio of 3). The method is highly reproducible, specific and sensitive, and the electrode has a rapid response. It was applied to the determination of lysozyme in egg white, serum, and urine. Graphical abstract Schematic of a nanocomposite composed of multi-walled carbon nanotubes (MWCNTs), poly(diallyldimethyl ammonium chloride) (PDDA), and carbon quantum dots (CQDs) for use in a lysozyme aptasensor. The aptamer was immobilized on the surface, and bovine serum albumin (BSA) was applied to block the surface. The changes of peak current for the electrochemical probe hexacyanoferrate (Fe(CN)63-/4-) in the presence and absence of lysozyme was traced. PMID- 29594453 TI - Determination of trace uric acid in serum using porous graphitic carbon nitride (g-C3N4) as a fluorescent probe. AB - Porous graphitic carbon nitride (g-C3N4) was prepared by a one-step acid etching and ultrasonication process. It is found that the strong blue fluorescence of g C3N4 (with excitation/emission maxima at 320/400 nm) is fairly selectively quenched by uric acid (UA). The morphology and chemical structure of the nanoporous g-C3N4 were characterized by XRD, TEM and FTIR. Quenching studies and Stern-Volmer plots reveal two UA concentration ranges of different quenching efficiency. The first extends from 50 to 500 nM, the other from 0.5 to 10 MUM. The limit of detection is 8.4 nM. The two quenching processes are attributed to both dynamic and static quenching. The porous g-C3N4 probes were applied to the determination of UA in (spiked) human serum and human plasma, and the results were as good as those obtained with UA standard solutions. These data illustrate that g-C3N4 can be used to selectively and sensitively quantify trace levels of UA even in a complex environment. Graphical abstract Porous graphite nitride carbon (g-C3N4) is shown to be a viable fluorescent probe for uric acid (UA) via both dynamic and static quenching. The electron transfer of carbon nitride is represented by the arrows; hnu is the incident light; PL is the fluorescence emission. PMID- 29594454 TI - Cyclodextrin-modified nanodiamond for the sensitive fluorometric determination of doxorubicin in urine based on its differential affinity towards beta/gamma cyclodextrins. AB - The manuscript reports on the preparation of beta-cyclodextrin-modified nanodiamonds (betaCD-ND) for the extraction and preconcentration of the fluorescent anticancer drug doxorubicin (DOX) from biological samples. The inclusion of DOX into the cavities of beta- and gamma-cyclodextrin (CD) confirms their utility for selective extraction and elution of the drug based on its good fit to the cyclodextrin cavity. Although both larger cyclodextrins (betaCD and gammaCD) accommodate DOX, DOX clearly prefers the bigger gammaCD cavities. Dispersive micro solid-phase extraction using betaCD-ND as sorbent enables the inclusion complexation of DOX. The elution of DOX from betaCD-ND cavities occurs with a basic solution of gammaCD containing 10% acetonitrile owing to the preferential affinity (i.e. optimal fit) of DOX into the larger gammaCD cavity. DOX is quantified by monitoring its intrinsic fluorescence (exc/em = 475/595 nm). The method can determine DOX in urine with a limit of detection of 18 ng.mL-1. Recoveries (93.2% and 94.0%) and precision (RSDs of 5.9% and 4.7%) at 100 and 400 ng.mL-1 DOX levels in urine are satisfactory. The matrix effect is negligible even when working with undiluted urine samples. Graphical abstract Nanodiamonds functionalized with beta-cyclodextrin (betaCD-ND) were used as sorbent for the determination of nanomolar levels of doxorubicin (DOX). It is based on host:guest interactions ruled by different stabilities of DOX within cyclodextrin (CD) cavity-size: betaCD/gammaCD.

AB - The authors report that carbon nitride quantum dots (CN QDs) exert a strong enhancing effect on the Cu(II)/H2O2 chemiluminescent system. Chemiluminescence (CL) intensity is enhanced by CN QDs by a factor of ~75, while other carbon nanomaterials have a much weaker effect. The possible mechanism of the effect was evaluated by recording fluorescence and CL spectra and by examining the effect of various radical scavengers. Emitting species was found to be excited-state CN QDs that produce green CL peaking at 515 nm. The new CL system was applied to the sensitive detection of H2O2 and glucose (via glucose oxidase-catalyzed formation of H2O2) with detection limits (3sigma) of 10 nM for H2O2 and 100 nM for glucose. The probe was employed for glucose determination in human plasma samples with satisfactory results. Graphical abstract The effect of carbon nitride quantum dots (CN QDs) on Cu(II)-H2O2 chemiluminescence reaction was studied and the new CL system was applied for sensitive detection of glucose based on the glucose oxidase (GOx)-catalyzed formation of H2O2. PMID- 29594456 TI - Combined pharmacotherapy for osteonecrosis of the femoral head after severe acute respiratory syndrome and interstitial pneumonia: two and a half to fourteen year follow-up. AB - PURPOSE: The purpose of this study was to retrospectively analyze the clinical, functional, and radiological outcomes of combined pharmacotherapy to ONFH after high-dose corticosteroid therapy. METHOD: From August 2003 to June 2015, five patients (ten hips) of ONFH in ARCO stage I, after SARS and Interstitial pneumonia, were treated by combined pharmacotherapy. Lipo-prostaglandin E1 10 MUg iv Bid * 28 days, enoxaparin 6000 iu H QD * 12 weeks, alendronate sodium tablet 10 mg QD * 1 year. The patients were fully weight-bearing following completion of the follow-up. RESULT: For these five patients (ten hips), Harris score was 100 from the diagnosis to final follow-up time. Radiologic findings show no signs of collapse, necrotic focus was repaired, and ARCO stages were changed from IC into IIB. CONCLUSION: This combined pharmacotherapy has promising treatment results for delaying or preventing collapse of ONFH in ARCO stage I.

AB - A magnetic micro-solid phase extraction method was applied for the extraction of trace levels of various chlorophenols prior to their determination by high performance liquid chromatography. The reduced graphene oxide functionalized with magnetic iron oxide nanoparticles and graphitic carbon nitride was prepared and used as adsorbent. It was characterized by scanning electron microscope, X-ray diffraction and vibrating sample magnetometer. Placed in a polypropylene hollow tube, the material was applied to the extraction of 3-chlorophenol, 2,3 dichlorophenol, 2,4-dichlorophenol, and 2,4,6-trichlorophenol in cosmetic samples. Several experimental parameters that affect extraction efficiency were optimized. Following desorption with alkaline methanol, the chlorophenols were quantified by high performance liquid chromatography. A linear response was observed in the 1.0-200 MUg.kg-1 CP concentration ranges. The detection limits (at a signal-to-noise ratio of 3) are between 0.20 and 0.30 MUg.kg-1. The relative recoveries of the CPs from spiked cosmetics samples were in the range from 80.5 to 104%, with relative standard deviations lower than 12%. The filled extraction tube is high durable and stable. It can be used for 120 extraction cycles without a significant loss of extraction efficiency. The good adsorption ability of the sorbent was attributed to the strong pi stacking interaction between the graphitic carbon nitride functionalized reduced graphene oxide and the aromatic rings in the CPs. Graphical abstract A magnetic micro-solid phase extraction (M-MUSPE) method was applied to the extraction of various trace chlorophenols prior to their determination by high performance liquid chromatography. The M-MUSPE method combines the advantages of both MSPE and MUSPE. PMID- 29594459 TI - Iron storage disease (hemochromatosis) and hepcidin response to iron load in two species of pteropodid fruit bats relative to the common vampire bat. AB - Hepcidin is the key regulator of iron homeostasis in the body. Iron storage disease (hemochromatosis) is a frequent cause of liver disease and mortality in captive Egyptian fruit bats (Rousettus aegyptiacus), but reasons underlying this condition are unknown. Hereditary hemochromatosis in humans is due to deficiency of hepcidin or resistance to the action of hepcidin. Here, we investigated the role of hepcidin in iron metabolism in one species of pteropodid bat that is prone to iron storage disease [Egyptian fruit bat (with and without hemochromatosis)], one species of pteropodid bat where iron storage disease is rare [straw-colored fruit bat (Eidolon helvum)], and one species of bat with a natural diet very high in iron, in which iron storage disease is not reported [common vampire bat (Desmodus rotundus)]. Iron challenge via intramuscular injection of iron dextran resulted in significantly increased liver iron content and histologic iron scores in all three species, and increased plasma iron in Egyptian fruit bats and straw-colored fruit bats. Hepcidin mRNA expression increased in response to iron administration in healthy Egyptian fruit bats and common vampire bats, but not in straw-colored fruit bats or Egyptian fruit bats with hemochromatosis. Hepcidin gene expression significantly correlated with liver iron content in Egyptian fruit bats and common vampire bats, and with transferrin saturation and plasma ferritin concentration in Egyptian fruit bats. Induction of hepcidin gene expression in response to iron challenge is absent in straw-colored fruit bats and in Egyptian fruit bats with hemochromatosis and, relative to common vampire bats and healthy humans, is low in Egyptain fruit bats without hemochromatosis. Limited hepcidin response to iron challenge may contribute to the increased susceptibility of Egyptian fruit bats to iron storage disease. PMID- 29594458 TI - Host genetics in malaria: lessons from mouse studies. AB - Malaria remains a deadly parasitic disease caused by Plasmodium, claiming almost half a million lives every year. While parasite genetics and biology are often the major targets in many studies, it is becoming more evident that host genetics plays a crucial role in the outcome of the infection. Similarly, Plasmodium infections in mice also rely heavily on the genetic background of the mice, and often correlate with observations in human studies, due to their high genetic homology with humans. As such, murine models of malaria are a useful tool for understanding host responses during Plasmodium infections, as well as dissecting host-parasite interactions through various genetic manipulation techniques. Reverse genetic approach such as quantitative trait loci studies and random mutagenesis screens have been employed to discover novel host genes that affect malaria susceptibility in mouse models, while other targeted studies utilize mouse models to validate observation from human studies. Herein, we review the findings from the past and present studies on murine models of hepatic and erythrocytic stages of malaria and speculate on how the current mouse models benefit from the recent development in CRISPR/Cas9 gene editing technology. PMID- 29594460 TI - Does endoscopic puncture of ureterocele provide not only an initial solution, but also a definitive treatment in all children? Over the 26 years of experience. AB - PURPOSE: We have retrospectively evaluated all patients who underwent endoscopic puncture (EP) of ureterocele over the last 26 years with special reference to the need in the second intervention and disease-free status. METHODS: 78 (69%) of the 112 patients following EP and completed follow-up were included. 51 (65%) were diagnosed prenatally and 27 (35%) postnatally. 46 patients (60%) had intravesical, while 32 (40%) had ectopic ureterocele. Median age at time of puncture was 4 months. Median time of the follow-up was 12 years (range 1-26 years), while 23 (30%) followed over 10 years and 15 (19%) completed adolescent period. RESULTS: Four children with ectopic ureterocele required secondary puncture. Ectopic ureterocele children had significantly more postoperative UTIs (13 (40%) ectopic vs 4 (19%) intravesical p = 0.047). 19 RRUs (44%) showed spontaneous resolution of VUR. 14 (18%) children required additional surgery: 7, endoscopic correction of VUR; 3, ureteral reimplantation and 4, partial nephrectomy. The need for additional surgery following puncture was higher in the group of children with ectopic ureterocele; however, this difference did not reach a statistical significance (p = 0.716). CONCLUSIONS: Our data show that EP of ureterocele is a durable and long-term effective procedure in vast majority of the children.

AB - BACKGROUND/PURPOSE: Anaplastic ganglioglioma (AGG) is a rare tumor with both glial and neuronal component accounting for less than 1% of all CNS tumors with limited information about the optimum treatment and outcome of these tumors. METHOD AND MATERIALS: We did a thorough search of the PubMed with the following MesH terms: "Ganglioglioma; Anaplastic ganglioglioma; Ganglioglioma AND treatment; and Anaplastic ganglioglioma AND survival" to find all possible publications related to AGG to perform an individual patient data analysis and derive the survival outcome and optimum treatment of these tumors. RESULTS: A total of 56 articles were retrieved pertaining to AGG with 88 patients. However, a total of 40 publications found eligible with 69 patients for individual patient data analysis. Median age for the entire cohort was 16 years (range 0.2-77 years). Surgical details were available for 64 patients. A gross total or near total resection was reported in 21 cases (32.8%), subtotal resection or debulking was reported in 25 cases (39.1%). Surgical details were available for 64 patients. A gross total or near total resection was reported in 21 cases (32.8%), and subtotal resection or debulking was reported in 25 cases (39.1%). Median overall survival (OS) was 29 months [95% CI 15.8-42.2 months] with 2- and 5-year OS 61 and 39.4% respectively. CONCLUSION: AGG is associated with a dismal. Pediatric age and a gross total resection of tumor confer a better progression free survival and OS. Hence, surgery should remain the cornerstone of therapy. However, because of modest survival, there is enough opportunity to improve survival with addition of adjuvant radiation and chemotherapy. A whole genome sequencing and molecular characterization would help to derive the best treatment option. PMID- 29594462 TI - Placode rotation in transitional lumbosacral lipomas: are there implications for origin and mechanism of deterioration? AB - PURPOSE: Rotation of the lipoma-neural placode has been noted in transitional lumbosacral lipomas. The purpose of this study was to confirm this rotation; that this rotation occurs with a preference to the left, and correlates with clinical symptoms. In addition, this study tests the hypothesis that this rotation occurs through local mechanical forces rather than intrinsic congenital malformation. METHODS: Lipomas were classified as per the Chapman classification. Degree of rotation of the placode from the coronal plane was recorded along with the presence of herniation outside of the vertebral canal. Abnormalities on urodynamic testing were recorded, along with neuro-orthopaedic signs picked up on formal neuro-physiotherapy assessment. RESULTS: Placode rotation occurs more frequently in the transitional group. Regardless of lipoma classification, rotation was much more common to the left. Furthermore, when lateralisation of symptoms was present, this strongly correlated with the direct of rotation. There was no difference in rotation of the placode whether it was within (lipomyelocoele) or without the vertebral canal (lipomyelomeningocoele). CONCLUSIONS: Placode rotation is a feature of transitional lumbosacral lipomas and may account for the increase in symptoms amongst this subgroup. Herniation of the placode outside the vertebral canal does not increase the risk of rotation suggesting a congenital cause for this finding rather than a purely mechanical explanation. PMID- 29594463 TI - Traumatic brain injury in Indian children. AB - INTRODUCTION: Traumatic brain injury (TBI) in children and adolescents is a community-based medical and educational challenge world-over due to increasing urbanization and motorization. In India, children between 1 to 15 years constitute significant proportion of the total population, who are vulnerable for TBI. In developed countries, pediatric trauma mortality still represents more than half of all childhood fatalities, which is 18 times more common than brain tumors. In this study, we attempted to analyze epidemiological factors, management, and outcome of TBI in children at a tertiary care center in Pune, Maharashtra. AIM AND OBJECTIVES: To study the clinical spectrum of pediatric traumatic brain injury cases received at a Tertiary Care Hospital. MATERIALS AND METHODS: This prospective study (August 2015-July 2017), conducted at our institution, includes all children < 16 years with TBI reporting to the neurosurgical emergency department. All the case records were reviewed and the pertinent data (clinical history, age, sex, mode of injury, computed tomography (CT) scan findings, interventions, morbidity, and mortality) analyzed. Any residual neurological deficits at the time discharge were assessed as the outcome of TBI. RESULTS: A total 76 pediatric cases of TBI were admitted during the period of August 2015-July 2017, with 51 males (67%) and 25 females (33%) with male to female ratio 2:1. Mean age of incidence in our study is 5.5 years. Out of 76 children with TBI, 60.5% were of mild, 14.5% moderate, and 25% severe TBI. Overall, RTA (40.8%) is the most common mode of injury followed by fall from height (30.2%) and slippage in and around home (26.4%). Clinical evaluation revealed, loss of consciousness(LOC) in 36 (47.3%) patients, vomiting in 42 (55%) patients, headache in 10 (13%) patients, ENT bleeding in 18 (23.6%), and seizure in 16 (21%) patients, no external injuries in 25 (33%) patients, normal sensorium was found in 41 (54%) patients, 18 (23.6%) children were drowsy at presentation, and 17 (22.3%) children were unconscious. CT scan findings revealed no gross abnormality in (26%), extradural heamorrhage (EDH) (18.4%), subdural hemorrhage (SDH) (14.4%), subarachnoid hemorrhage (21%), fracture skull (55.26%), cerebral oedema, and contusion (48.68%) as the radiological injury patterns. Out of 76 children, 42 (55%) children are managed with only observation, 26 (34%) children required only medical pharmacological treatment, and 8 (10.5%) children required surgical intervention, 24, (31.6%) children required mechanical ventilation. Overall mortality is 5.26%. Thus among the survivors (n = 72), 57 (79%) went home with no residual deficit, 3 (4%) had headache, 4 (5.5%) had hemiparesis, 2 (2.7%) had monoparesis, 1 (1.4%) had hypertonia, 3 (4%) had seizures, 2 (2.7%) had hydrocephalus, 2 (2.7%) had facial palsy, 2 (2.7%) had vision impairment, and 2 (2.7%) had speech impairment. In our study, we found that there is a significant association between residual deficits and severity of injury (p = 0.3), there is no significant association between mode of injury and outcome (p = 0.7). Mean duration of stay in hospital was 6.9 days but 60% of patients had stay of less than 5 days. CONCLUSION: Most of these injuries are preventable in infancy and childhood by ensuring proper vigilance, tender care by the parents and the caretakers. Safe driving techniques have to be followed by parents while traveling with children in their motor vehicles. Need to focus on grading the severity of TBI rather than on factors like age, mode of injury, and presence or absence of external injuries.

However, having an awareness of those findings which are specific to a certain entity is important when interpreting imaging studies. These classic findings can be identified with many imaging modalities, but no modality provides as many recognizable observations as an MRI. This results from the large variety of pulse sequences that provide high contrast resolution, prior to and following contrast administration. In this article, the most classically recognized abdominal findings are presented including the following: Liver: Cyst, hemangioma, focal nodular hyperplasia, hepatic adenoma, hemosiderosis, hepatocellular carcinoma. Spleen: Cyst, hemangioma, lymphangioma, hemosiderosis, Gandy-Gamna bodies. Biliary system: Biliary stones and choledocholithiasis, pneumobilia, choledochal cyst. Gallbladder: Adenomyomatosis, sludge, surgical clips in the gallbladder fossa. Pancreas: Pancreatic divisum, intraductal papillary mucinous neoplasm, pseudocyst, autoimmune pancreatitis, chronic pancreatitis, adenocarcinoma. Kidneys: Simple cyst, hemorrhagic cyst, renal sinus cyst, angiomyolipoma, solid mass. PMID- 29594464 TI - Heavy metal tolerance in marine strains of Yarrowia lipolytica. AB - Heavy metal tolerance of two marine strains of Yarrowia lipolytica was tested on solid yeast extract peptone dextrose agar plates. Based on minimum inhibitory concentration esteems, it is inferred that the two strains of Y. lipolytica were tolerant to heavy metals such as Pb(II), Cr(III), Zn(II), Cu(II), As(V), and Ni(II) ions. The impact of various heavy metal concentrations on the growth kinetics of Y. lipolytica was likewise assessed. With increased heavy metal concentration, the specific growth rate was reduced with delayed doubling time. Furthermore, biofilm development of both yeasts on the glass surfaces and in microtitre plates was assessed in presence of different heavy metals. In microtitre plates, a short lag phase of biofilm formation was noticed without the addition of heavy metals in yeast nitrogen base liquid media. A lag phase was extended over increasing metal concentrations of media. Heavy metals like Cr(VI), Cd(II), and As(V) are contrastingly influenced on biofilms' formation of microtitre plates. Other heavy metals did not much influence on biofilms development. Thus, biofilm formation is a strategy of Y. lipolytica under stress of heavy metals has significance in bioremediation process for recovery of heavy metals from contaminated environment.

AB - PURPOSE: The purpose of this study was to evaluate the relationship between final outcome of lesions indeterminate for malignancy on ultrasound (US) and patient and imaging characteristics. METHODS: We identified all patients with indeterminate liver lesions on US between 9/1/2013 and 12/31/2014 using institutional codes based on radiologist opinion. Miscoded lesions (n = 30) and patients with no imaging, pathology, or clinical follow-up at our health system (n = 6) were excluded. Final diagnostic category of malignant, benign, pseudolesion, or indeterminate was assigned using imaging, pathology, and clinical follow-up. Differences in diagnostic categories were compared by patient (age, gender, race, known malignancy. or liver disease) and imaging characteristics (lesion size, echogenicity. and number). Independent likelihood of a benign final diagnostic category was adjusted for significant variables on univariate analysis. RESULTS: Indeterminate liver lesions on US were found in 153/6813 patients (2%). Final diagnostic categories were malignant (11/153, 7%), benign (94/153, 61%), pseudolesion (42/153, 27%). and indeterminate (6/153, 4%). Nearly one-third of hypoechoic masses in patients with known malignancy or liver disease (i.e., high-risk status) >= 46 years of age were malignant (9/28, 32%). On multivariate analysis, patients of age >= 61 years and high-risk status were associated with decreased likelihood of benign diagnostic category (OR .19 (95% CI .07-.51) and OR .40 (95% CI .18-.88), p values .001 and .022, respectively). CONCLUSIONS: 2% of patients undergoing abdominal US have sonographically indeterminate liver lesions, of which 7% are malignant. Older, high-risk patients with hypoechoic lesions should receive short-term follow-up as one-third will have malignant lesions. Younger, low-risk patients should receive conservative follow-up, regardless of US imaging features.

AB - OBJECTIVE: Pancreatic neuroendocrine tumors (PanNETs) are uncommon pancreatic neoplasms and can be a diagnostic challenge with heterogeneous spectrum of CT appearance. We review CT findings of PanNETs and other mimics. CONCLUSION: PanNETs are typically hypervascular and have avid enhancement on arterial and venous phase images. However, dedicated pancreas protocol may be needed due to their sometimes atypical appearance including transient enhancement. Careful evaluation of CT findings will help differentiate PanNETs from their mimics, and can be used to establish the diagnosis of a PanNETs. Although an accurate diagnosis can be based on serological, urine, and CT scan findings, confirmation is made via pathological examination. PMID- 29594468 TI - Extensive spinal extradural ganglioneuroma of the lumbar spine: mimicking lymphoma. AB - BACKGROUND: Ganglioneuromas are rare, benign, well-differentiated tumors arising from neural crest cells that commonly occur in the posterior mediastinum, retroperitoneum, cervical spine, and adrenal gland. We report an unusual case of an extensive spinal extradural ganglioneuroma, circumferentially and longitudinally affecting the extradural space of the lumbar spine and continuously invading bilateral psoas muscles. CASE DESCRIPTION: A 32-year-old man presented with a 1-week history of abdominal pain and diarrhea. Radiographs revealed scalloping of the posterior surfaces of the L2 and L3 vertebral bodies and widening of L2-3 and L3-4 bilateral intervertebral foramina. Computed tomography scans and magnetic resonance imaging showed a well-defined lobulated extradural mass from L1 to L4 and a continuously forming mass in the psoas muscles through L2-3 bilateral neural foramina. The mass demonstrated homogeneously isointense signal on T1-weighted images, inhomogeneously hyperintense-to-isointense signal on T2-weighted images, and inhomogeneous enhancement on fat-suppressed contrast-enhanced T1-weighted images. Radiologic diagnosis included spinal epidural lymphoma. Percutaneous biopsy with sonographic guidance was performed, and the mass was diagnosed on pathological examination as a ganglioneuroma. CONCLUSIONS: This is the first known reported case in the literature of a spinal extradural ganglioneuroma with circumferentially and longitudinally extensive involvement of the extradural space and a large psoas mass.

AB - PURPOSE: We sought to determine the incidence and timing of testicular atrophy following inguinal hernia repair in children. METHODS: We used the TRICARE database, which tracks care delivered to active and retired members of the US Armed Forces and their dependents, including > 3 million children. We abstracted data on male children < 12 years who underwent inguinal hernia repair (2005 2014). We excluded patients with history of testicular atrophy, malignancy or prior related operation. Our primary outcome was the incidence of the diagnosis of testicular atrophy. Among children with atrophy, we calculated median time to diagnosis, stratified by age/undescended testis. RESULTS: 8897 children met inclusion criteria. Median age at hernia repair was 2 years (IQR 1-5). Median follow-up was 3.57 years (IQR 1.69-6.19). Overall incidence of testicular atrophy was 5.1/10,000 person-years, with the highest incidence in those with an undescended testis (13.9/10,000 person-years). All cases occurred in children [Formula: see text] 5 years, with 72% in children < 2 years. Median time to atrophy was 2.4 years (IQR 0.64-3), with 30% occurring within 1 year and 75% within 3 years. CONCLUSION: Testicular atrophy is a rare complication following inguinal hernia repair, with children < 2 years and those with an undescended testis at highest risk. While 30% of cases were diagnosed within a year after repair, atrophy may be diagnosed substantially later. LEVEL OF EVIDENCE: Prognosis Study, Level II. PMID- 29594471 TI - Enzymatic biosensing by covalent conjugation of enzymes to 3D-networks of graphene nanosheets on arrays of vertically aligned gold nanorods: Application to voltammetric glucose sensing. AB - The authors demonstrate efficient direct electron transfer from the enzyme glucose oxidase to vertically aligned gold nanorods with a diameter of ~160 nm and a length of ~2 MUm that are covalently linkage to a 3-dimensional network of reduced graphene oxide nanosheets. The assembly can be prepared by a 2-step electrochemical procedure. This hybrid structure holds the enzyme in a favorable position while retaining its functionality that ultimately provides enhanced performance for enzymatic sensing of glucose without utilizing mediators. The nanorod assembly was applied to the voltammetric detection of glucose. Figures of merit include an electrochemical sensitivity of 12 MUA.mM-1.cm-2 (obtained from cathodic peak current at a voltage of -0.45 V vs. Ag/AgCl), a 3 MUM detection limit (at signal/noise = 3), and a wide linear range (0.01-7 mM). The hybrid nanostructure has a heterogeneous electron transfer rate constant (ks) of 2.9 s 1. The high electrochemical activity is attributed to the synergistic effect of a large active surface and an enhanced electron transfer efficiency due to covalent amide linkage. Graphical Abstract Schematic of the procedure utilized for the fabrication of an electrochemical biosensor based on gold nanorods (AuNRs) modified with a reduced graphene oxide (rGO)/glucose oxidase (GOx) conjugate. The enzyme electrode was employed to the determination of glucose by differential pulse voltammetry.

AB - A method is described for the matrix assisted laser desorption/ionization time-of flight (MALDI-TOF)-based determination of benzo[a]pyrene (BaP) by using the metal organic framework MIL-101(Fe) as a matrix. Following optimization of the experimental parameters, the method has a detection limit as low as 0.1 MUg.L-1, which makes it more sensitive than previous methods for BaP analysis, and its analysis time is only 1 min. Its applicability was evaluated by analyzing sesame oil, linseed oil, camellia seed oil, and olive oil spiked with BaP at three levels (10, 1, and 0.5 MUg.kg-1), and the recovery range was found to range from 80.0 to 114.8% with relative standard deviations (RSDs) between 3.9 and 13.7%. Graphical abstract The metal-organic framework MIL-101(Fe) was applied as a new matrix to the quantitative detection of benzo[a]pyrene (BaP) by matrix assisted laser desorption/ionization time-of-flight (MALDI-TOF). PMID- 29594473 TI - Determination of norfloxacin or ciprofloxacin by carbon dots fluorescence enhancement using magnetic nanoparticles as adsorbent. AB - The authors describe a method for the determination of norfloxacin (NOR) or ciprofloxacin (CIP). It is making use of a combination of fluorescence enhancement and magnetic solid-phase extraction (MSPE). Sulfur-doped carbon dots (S-CDs) are used as a fluorescent probe. They were prepared by a one-pot method using poly(4-styrenesulfonic acid-co-maleic acid) (PSMA) as a source for carbon and sulfur. NOR or CIP act as sensitizers of fluorescence (with excitation/emission maxima at 324/412 nm), probably due to strong hydrogen bond interaction and charge transfer with the S-CDs. The S-CDs were characterized by using TEM, XRD, XPS, FT-IR, UV-Vis and fluorescence spectroscopies. Response is linear in the 0.02-1.25 MUM NOR concentration range, and the detection limit is 4.6 nM. The respective data for CIP are 0.02-1.0 MUM and 6.7 nM. The average recoveries of NOR and CIP residues from spiked bovine raw milk are 96.2%~105.2% and 92.3%~102.5%. Graphical abstract Sulfur doped carbon dots (S-CDs) were synthesized by a hydrothermal method using poly(4-styrenesulfonic acid-co-maleic acid) (PSMA). Norfloxacin (NOR) or ciprofloxacin (CIP) was extracted by magnetic nanoparticles (MNPs), they were detected by carbon dots fluorescence enhancement. PMID- 29594474 TI - Fluorometric determination of lead(II) and mercury(II) based on their interaction with a complex formed between graphene oxide and a DNAzyme. AB - The authors have designed a DNAzyme where graphene oxide (GO) interacts with the ssDNA stem loop region. The DNAzyme strand and substrate strand are hybridized and bind to the surface of GO which act as a signal reporter, while GO act as a strong quencher. The presence of Pb(II) ion disturbs the GO-DNAzyme complex and causes internal cleavage of the DNAzyme complex. On addition of Thioflavin T (ThT) as a quadruplex inducer, fluorescence intensity (best measured at excitation/emission peaks of 425/490 nm) is strongly enhanced. Subsequent addition of Hg(II) to ThT/G-quadruplex complex decreases fluorescence because the G-quadruplex is unwinding to form a T-Hg(II)-T dsDNA system. Therefore, the change in fluorescence intensity of ThT is directly correlated to the concentration of Pb(II) and Hg(II). As a result, the assay is highly selective and sensitive. The limits of detection are 96 pM for Pb(II) and 356 pM for Hg(II). Moreover, the method was applied to the detection of the two ions in spiked real samples and gave satisfactory results. Graphical abstract A label free sensitive and selective "on-off" fluorescent assay for detection of Pb(II) and Hg(II) based on graphene oxide -DNAzyme complex with fluorogenic dye thioflavin T. The limits of detection are 96 pM (Pb2+) and 356 pM (Hg2+). PMID- 29594475 TI - Individual fatty acids in erythrocyte membranes are associated with several features of the metabolic syndrome in obese children. AB - PURPOSE: Obesity leads to the clustering of cardiovascular (CV) risk factors and the metabolic syndrome (MetS) also in children and is often accompanied by non alcoholic fatty liver disease. Quality of dietary fat, beyond the quantity, can influence CV risk profile and, in particular, omega-3 fatty acids (FA) have been proposed as beneficial in this setting. The aim of the study was to evaluate the associations of individual CV risk factors, characterizing the MetS, with erythrocyte membrane FA, markers of average intake, in a group of 70 overweight/obese children. METHODS: We conducted an observational study. Erythrocyte membrane FA were measured by gas chromatography. Spearman correlation coefficients (rS) were calculated to evaluate associations between FA and features of the MetS. RESULTS: Mean content of Omega-3 FA was low (Omega-3 Index = 4.7 +/- 0.8%). Not omega-3 FA but some omega-6 FA, especially arachidonic acid (AA), were inversely associated with several features of the MetS: AA resulted inversely correlated with waist circumference (rS = - 0.352), triglycerides (rS = - 0.379), fasting insulin (rS = - 0.337) and 24-h SBP (rS = - 0.313). Total amount of saturated FA (SFA) and specifically palmitic acid, correlated positively with waist circumference (rS = 0.354), triglycerides (rS = 0.400) and fasting insulin (rS = 0.287). Fatty Liver Index (FLI), a predictive score of steatosis based on GGT, triglycerides and anthropometric indexes, was positively correlated to palmitic acid (rS = 0.515) and inversely to AA (rS = - 0.472). CONCLUSIONS: Our data suggest that omega-6 FA, and especially AA, could be protective toward CV risk factors featuring the MetS and also to indexes of hepatic steatosis in obese children, whereas SFA seems to exert opposite effects. PMID- 29594476 TI - Geographic and socioeconomic diversity of food and nutrient intakes: a comparison of four European countries. AB - PURPOSE: Public health policies and actions increasingly acknowledge the climate burden of food consumption. The aim of this study is to describe dietary intakes across four European countries, as baseline for further research towards healthier and environmentally-friendlier diets for Europe. METHODS: Individual level dietary intake data in adults were obtained from nationally-representative surveys from Denmark and France using a 7-day diet record, Italy using a 3-day diet record, and Czech Republic using two replicates of a 24-h recall. Energy standardised food and nutrient intakes were calculated for each subject from the mean of two randomly selected days. RESULTS: There was clear geographical variability, with a between-country range for mean fruit intake from 118 to 199 g/day, for vegetables from 95 to 239 g/day, for fish from 12 to 45 g/day, for dairy from 129 to 302 g/day, for sweet beverages from 48 to 224 ml/day, and for alcohol from 8 to 15 g/day, with higher intakes in Italy for fruit, vegetables and fish, and in Denmark for dairy, sweet beverages and alcohol. In all countries, intakes were low for legumes (< 20 g/day), and nuts and seeds (< 5 g/day), but high for red and processed meat (> 80 g/day). Within countries, food intakes also varied by socio-economic factors such as age, gender, and educational level, but less pronounced by anthropometric factors such as overweight status. For nutrients, intakes were low for dietary fibre (15.8-19.4 g/day) and vitamin D (2.4-3.0 ug/day) in all countries, for potassium (2288-2938 mg/day) and magnesium (268-285 mg/day) except in Denmark, for vitamin E in Denmark (6.7 mg/day), and for folate in Czech Republic (212 ug/day). CONCLUSIONS: There is considerable variation in food and nutrient intakes across Europe, not only between, but also within countries. Individual-level dietary data provide insight into the heterogeneity of dietary habits beyond per capita food supply data, and this is crucial to balancing healthy and environmentally-friendly diets for European citizens. PMID- 29594477 TI - Quercetin inhibits intestinal non-haem iron absorption by regulating iron metabolism genes in the tissues. AB - PURPOSE: There is general agreement that some dietary polyphenols block non-haem iron uptake, but the mechanisms by which they achieve this action are poorly understood. Since the polyphenol quercetin is ingested daily in significant amounts, we have investigated the effect of quercetin on duodenal non-haem iron absorption in vivo, as well as its effect on factors known to be involved in systemic iron metabolism. METHODS: Rats were subject to gastric gavage and systemic quercetin administration. Treatments were followed with uptake studies using radiolabeled iron, serum iron and transferrin saturation measurements, LC MS/MS analysis of quercetin metabolites in serum, determination of tissue non haem iron content and analysis of gene expression of iron-related proteins. RESULTS: Both oral and intraperitoneal (IP) quercetin caused serum and tissue iron depletion by two means, first by increasing mucosal iron uptake and inhibiting iron efflux from duodenal mucosa, and second by decreasing levels of duodenal DMT1, Dcytb and FPN. Additionally, IP quercetin induced highly significant increased liver expression of hepcidin, a hormone known to inhibit intestinal iron uptake. CONCLUSIONS: Oral quercetin significantly inhibited iron absorption, while IP quercetin significantly affected iron-related genes. These results could lead to development of new effective ways of preventing and treating iron deficiency anaemia, the most widespread nutritional disorder in the world.

PMID- 29594479 TI - Aptamer based fluorometric determination of ATP by exploiting the FRET between carbon dots and graphene oxide. AB - The authors describe a fluorometric aptamer based assay for adenosine triphosphate (ATP). It is based on the use of carbon dots (CDs) and graphene oxide (GO). The resultant CD-aptamer is adsorbed on the surface of GO via pi stacking and hydrophobic interaction, and the fluorescence of CD-aptamer is quenched via fluorescence resonance energy transfer (FRET) between CDs and GO. If ATP is present, it will bind to the aptamer and the CD-aptamer will be desorbed from GO. This will suppress FRET and the fluorescence of the CDs is restored. Under the optimal conditions and at typical excitation/emission wavelengths of 358/455 nm, the assay has a 80 pM detection limit and a linear range that extends from 0.10 to 5.0 nM concentrations of ATP. The method was successfully applied to the determination of ATP in yogurt samples. This method can also be conceivably applied to the detection of other analytes for which appropriate aptamers are available. Graphical abstract Schematic of a novel fluorometric ATP assay based on the fluorescence resonance energy transfer (FRET) between aptamer modified carbon dots (CD-aptamer) and graphene oxide (GO). CD-aptamer was used as the energy donor and molecular recognition probe, and GO acted as energy acceptor. This assay exhibits high sensitivity and selectivity with a detection limit as low as 80 pM. PMID- 29594480 TI - Aptamer based electrochemiluminescent thrombin assay using carbon dots anchored onto silver-decorated polydopamine nanospheres. AB - An electrochemiluminescent (ECL) aptamer based assay is described for thrombin. It is based on the use of carbon dots (C-dots) placed on polydopamine nanospheres loaded with silver nanoparticles (PDANS@Ag) and with probe DNA (pDNA). The PDANS possess high specific surface and can load a large number of C-dots. The AgNPs, in turn, enhance the ECL emission of the C-dots. Platinum functionalized graphene (Gr-Pt) can connect capture DNA (cDNA). The ECL nanoprobe consisting of PDANS@Ag/C-dots was placed on a glassy carbon electrode modified with Gr Pt/cDNA/BSA via hybridization between cDNA and pDNA. On applying voltages from 1.8 V to 0 V, a strong ECL signal is generated. If thrombin is added, it will bind to cDNA. This leads to the release of pDNA from the electrode surface and a decrease in ECL intensity. Response to thrombin is linear in the 1.0 fmol.L-1 to 5.0 nmol.L-1 concentration range, with a 0.35 fmol.L-1 detection limit. The assay is stable, repeatable and selective, which demonstrates its clinical applicability. Graphical abstract Carbon dots (C-dots) placed on polydopamine nanospheres loaded with silver nanoparticles (PDANS@Ag) for electrochemiluminescent (ECL) detection of thrombin. PMID- 29594481 TI - A graphene modified carbon ionic liquid electrode for voltammetric analysis of the sequence of the Staphylococcus aureus nuc gene. AB - The authors describe a voltammetric method for the detection of the nuc ssDNA sequence originating from Staphylococcus aureus by using a carbon ionic liquid electrode modified with electrodeposited three-dimensional graphene (3DGR). Probe ssDNA was electrostatically adsorbed on the modified electrode by a potentiostatic method. The porous structure and large surface area of 3DGR greatly increase the amount of immobilized probe ssDNA on the interface, which is beneficial for the reaction with target ssDNA. By using Methylene Blue (MB) as the electrochemical probe, the reduction peak current of MB (best measured at 0.30 V vs. SCE) can be used for detecting hybridization. The differential pulse voltammetric current of MB increases linearly in the 1.0 * 10-12 mol L-1 to 1.0 * 10-6 mol L-1 nuc concentration range, and the detection limit is 3.3 * 10-13 mol L-1 (at 3sigma). The DNA sensor was successfully applied to the determination of the PCR product of the gene in pork. Graphical abstract Response of an electrochemical DNA biosensor based on the use of a carbon ionic liquid electrode modified with three-dimensional graphene. It enables sensitive voltammetric detection of the specific sequence of the Staphylococcus aureus nuc gene. PMID- 29594482 TI - Myoglobin immobilized on mesoporous carbon foam in a hydrogel (selep) dispersant for voltammetric sensing of hydrogen peroxide. AB - Mesoporous carbon foam (MCF) was prepared by via the Pechini method which is facile and template-free. The MCF was characterized by field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction and BET surface area analysis. Afterwards, the MCF was dispersed in the natural hydrogel salep to give a composite. Finally, myoglobin was immobilized on the composite and then placed on a glassy carbon electrode (GCE). The modified GCE gives a distinct quasi-reversible redox peak during electroreduction of hydrogen perxide (H2O2). The estimated electron transfer coefficient (alpha) and the heterogeneous electron transfer rate constant (ks) for redox process of Mb are 0.54 and 2.25 s 1, respectively. The sensor, best operated at -0.2 V (vs. Ag/AgCl), responds to H2O2 in the 1.0 to 80 MUM H2O2 concentration range, with a 180 nM limit of detection (at S/N ratio of 3). The technique was applied to the determination of H2O2 in spiked fetal bovine serum samples.

AB - The study reports on the synthesis of a graphene aerogel@octadecylamine functionalized carbon quantum dots (GA@O-CQDs). The graphene oxide aqueous dispersion, O-CQDs aqueous dispersion and toluene were strongly mixed to make a toluene-in-water Pickering emulsion. The graphene oxide sheets in the aqueous phase are reduced by hydrazine hydrate, diffuse into the toluene droplets, and self-assemble into graphene oxide microgels. This is followed by freeze-drying and thermal annealing to obtain the GA@O-CQDs hybrid that has a three-dimensional structure of several microns. It was dispersed in ethanol and deposited on a glassy carbon electrode. The modified electrode was applied to differential pulse voltammetric determination of acetaminophen, best at a peak potential of 0.15 V (vs. Ag/AgCl). Figures of the merit include a wide linear response range (0.001 10 MUM) and a 0.38 nM of the detection limit (S/N = 3). The assay has been applied to the determination of acetaminophen in tablets.

PMID- 29594484 TI - Effects of Shengmai injection add-on therapy to chemotherapy in patients with non small cell lung cancer: a meta-analysis. AB - PURPOSE: Shengmai injection (SMI) has shown promising outcomes in the management of non-small cell lung cancer (NSCLC). This meta-analysis aimed to investigate the add-on effects of SMI to chemotherapy in NSCLC patients. METHODS: A comprehensive literature search was performed in the Cochrane Library, PubMed, Embase, CNKI, VIP, and Wanfang up to December 2017. Only randomized controlled trials (RCTs) evaluating SMI in combination with chemotherapy versus chemotherapy alone in NSCLC patients were eligible. The outcome measures were quality of life, chemotherapy-induced grade 3/4 myelosuppression or gastrointestinal reactions, and objective tumor response (equals complete response plus partial response). Pooled risk ratio (RR) with 95% confidence interval (CI) was used to evaluate dichotomous and continuous outcome, respectively. RESULTS: A total of 15 RCTs were included and analyzed. Meta-analysis showed that SMI combined with chemotherapy was associated with a significant improvement in Karnofsky Performance Status (RR 2.36; 95% CI 1.50-3.96) compared with the chemotherapy alone. Moreover, adjunctive treatment with SMI significantly reduced grade 3/4 myelosuppression (RR 0.61; 95% CI 0.46-0.81) and gastrointestinal reactions (RR 0.64; 95% CI 0.46-0.90). However, there was no significant difference in objective tumor response (RR 1.17; 95% CI 0.99-1.37) between two groups. CONCLUSIONS: SMI add-on therapy appeared to be more effective in improving quality of life and reducing chemotherapy-induced adverse effects. However, more well-designed RCTs are warranted to confirm the findings of this meta-analysis because of the suboptimal methodological quality of the included trials. PMID- 29594485 TI - Risk stratification of oxaliplatin induced peripheral neurotoxicity applying electrophysiological testing of dorsal sural nerve. AB - PURPOSE: We aimed to verify the predictiveness of dorsal sural nerve neurophysiological monitoring in obtaining risk stratification for oxaliplatin induced peripheral neurotoxicity (OXAPN). METHODS: We conducted a secondary analysis on a cohort of 110 colorectal cancer patients who were evaluated clinically and neurophysiologically before chemotherapy, at mid-treatment and at discontinuation. We applied the classification tree analysis method to predict the end-of-treatment OXAPN neurophysiological diagnosis, using data recorded at mid-treatment. We then ascertained the correlation between the obtained classes and neurological impairment at the end of treatment (Fisher's exact test). RESULTS: Dorsal sural nerve monitoring enabled us to stratify oxaliplatin-treated patients into risk classes with an implemented approach to neurophysiology application in this setting. Neurological outcome at discontinuation was predicted by neurophysiological monitoring performed during chemotherapy administration. CONCLUSIONS: We demonstrated the role that neurophysiology may play in clinical trials as an early surrogate marker that can predict OXAPN development at the end of treatment. Specifically, we propose abnormal dorsal sural sensory nerve testing as an early biomarker in identifying patients at high risk of eventually developing OXAPN. PMID- 29594486 TI - Perceptions of care and patient-reported outcomes in people living with neuroendocrine tumours. AB - BACKGROUND: Neuroendocrine tumours (NETs) are rare, and when metastatic NETs are incurable, the tumours are frequently slowly growing. Patients may be confronted with disease-specific problems and distinct issues when accessing health-care. We aimed to assess perceptions of care coordination, identify unmet needs, and examine if these varied by whether patients received specialist oncology care in a single hospital or shared between that and another hospital. We also quantified anxiety, depression, and NET-related physical symptoms. METHODS: We conducted a cross-sectional survey of 111 NET patients managed at Royal Brisbane and Women's Hospital. Validated surveys measured care coordination (CCCQ), unmet needs (SCNS SF34), anxiety and depression (HADS), and quality of life and symptoms (FACT). RESULTS: Participants were between 2 months and 27 years after diagnosis. The worst-ranked items on the CCCQ related to health professionals having a full case history, providing information about financial entitlements and asking about how well patients and their families were coping. People with shared care were significantly less satisfied with some aspects of care. One in three participants reported a moderate-to-high unmet need for help with fatigue and one in four with psychological concerns about their cancer spreading, uncertainty about their future, and about the worries of those close to them. Overall, 30% of participants had anxiety and 20% had depression and they had significantly lower physical and emotional well-being compared to the general population. CONCLUSIONS: NETs are experienced as a chronic illness. In addition to ongoing psychological and physical symptom management, improvements to case history documentation and discussions about coping and finance are recommended. PMID- 29594487 TI - 'Being with' or 'doing for'? How the role of an end-of-life volunteer befriender can impact patient wellbeing: interviews from a multiple qualitative case study (ELSA). AB - PURPOSE: To explore the perspectives of people anticipated to be in their last year of life, family carers, volunteers and staff on the impacts of receiving a volunteer-provided befriending service. Patient participants received up to 12 weeks of a volunteer-provided befriending intervention. Typically, this involved one visit per week from a trained volunteer. Such services complement usual care and are hoped to enhance quality of life. METHODS: Multiple case study design (n = 8). Cases were end-of-life befriending services in home and community settings including UK-based hospices (n = 6), an acute hospital (n = 1) and a charity providing support to those with substance abuse issues (n = 1). Data collection incorporated qualitative thematic interviews, observation and documentary analysis. Framework analysis facilitated within and across case pattern matching. RESULTS: Eighty-four people participated across eight sites (cases), including patients (n = 23), carers (n = 3), volunteers (n = 24) and staff (n = 34). Interview data are reported here. Two main forms of input were described-'being there' and 'doing for'. 'Being there' encapsulated the importance of companionship and the relational dynamic between volunteer and patient. 'Doing for' described the process of meeting social needs such as being able to leave the house with the volunteer. These had impacts on wellbeing with people describing feeling less lonely, isolated, depressed and/or anxious. CONCLUSION: Impacts from volunteer befriending or neighbour services may be achieved through volunteers taking a more practical/goal-based orientation to their role and/or taking a more relational and emotional orientation. Training of volunteers must equip them to be aware of these differing elements of the role and sensitive to when they may create most impact. TRIAL REGISTRATION: ISRCTN12929812. PMID- 29594488 TI - On-line packed magnetic in-tube solid phase microextraction of acidic drugs such as naproxen and indomethacin by using Fe3O4@SiO2@layered double hydroxide nanoparticles with high anion exchange capacity. AB - The authors describe a 3-component nanoparticle system composed of a silica coated magnetite (Fe3O4) core and a layered double (Cu-Cr) hydroxide nanoplatelet shell. The sorbent has a high anion exchange capacity for extraction anionic species. A simple online system, referred to as "on-line packed magnetic-in-tube solid phase microextraction" was designed. The nanoparticles were placed in a stainless steel cartridge via dry packing. The cartridge was then applied to the preconcentration acidic drugs including naproxen and indomethacin from urine and plasma. Extraction and desorption times, pH values of the sample solution and flow rates of sample solution and eluent were optimized. Analytes were then quantified by HPLC with UV detection. Under optimal conditions, the limits of detection range from 70 to 800 ng L-1, with linear responses from 0.1-500 MUg L-1 (water samples), 0.6-500 MUg L-1 (spiked urine), and 0.9-500 MUg L-1 (spiked plasma). The inter- and intra-assay precisions (RSDs, for n = 5) are in the range of 2.2-5.4%, 2.8-4.9%, and 2.0-5.2% at concentration levels of 5, 25 and 50 MUg L 1, respectively. The method was applied to the analysis of the drugs in spiked human urine and plasma, and good results were achieved. Graphical abstract Fe3O4@SiO2@CuCr-LDH magnetic nanoparticles were synthesized and packed in to a stainless steel column. The column was applied to solid phase microextraction of acidic drugs from biological samples.

AB - BACKGROUND: Clostridium difficile infection (CDI) is the most common hospital acquired infection. Unfortunately, genes that identify CDI-susceptible patients have not been well described. We performed a genome-wide association study (GWAS) to determine genetic variants associated with the development of CDI. METHODS: A cohort study of Caucasian patients undergoing autologous stem cell transplantation for multiple myeloma was performed. Patients were genotyped using Illumina(r) Whole Genome Genotyping Infinium chemistry. We then compared CDI positive to CDI-negative patients using logistic regression for baseline clinical factors and false discovery rate (FDR) for genetic factors [single nucleotide polymorphisms (SNPs)]. SNPs associated with CDI at FDR of p < 0.01 were then incorporated into a logistic regression model combining clinical and genetic factors. RESULTS: Of the 646 patients analyzed (59.7% male), 57 patients were tested CDI positive (cases) and were compared to 589 patients who were tested negative (controls). Hemoglobin, albumin, and hematocrit were lower for cases (p < 0.05). Eight SNPs on five genes (FLJ16171, GORASP2, RLBP1L1, ASPH, ATP7B) were associated with CDI at FDR p < 0.01. In the combined clinical and genetic model, low albumin and three genes RLBP1L1, ASPH, and ATP7B were associated with CDI. CONCLUSION: Low serum albumin and genes RLBP1L1 and ASPH located on chromosome 8 and ATP7B on chromosome 13 were associated with CDI. Of particular interest is ATP7B given its copper modulatory role and the sporicidal properties of copper against Clostridium difficile.

AB - OBJECTIVE: To identify the frequency and characteristics of bleeding complications during acute inpatient rehabilitation of hematologic malignancy patients with severe thrombocytopenia. DESIGN: Retrospective descriptive analysis. SETTING: Comprehensive cancer center acute inpatient rehabilitation unit. PARTICIPANTS: Consecutive hematologic malignancy patients with a platelet count of less than or equal to 20,000/microliter (MUL) on the day of acute inpatient rehabilitation admission from 1/1/2005 through 8/31/2016. INTERVENTIONS: Medical records were retrospectively analyzed for demographic, laboratory, and medical data. Patients were rehabilitated using the institutional exercise guidelines for thrombocytopenic patients. MAIN OUTCOME MEASURES: Bleeding events noted in the medical record. RESULTS: Out of 135 acute inpatient rehabilitation admissions, 133 unique patients were analyzed with a total of 851 inpatient rehabilitation days. The mean platelet count was 14,000/MUL on the day of admission and 22,000/MUL over the course of the rehabilitation admission. There were 252 days of inpatient rehabilitation where patients had less than 10,000/MUL platelets. A total of 97 bleeding events were documented in 77/135 (57%) admissions. Of the 97 bleeding events, 72 (74%), 14 (14%), and 11 (11%) were considered to be of low, medium, and high severity, respectively. There were 4/97 (4%) bleeding events that were highly likely attributable to physical activity but only 1/4 was considered high severity. Bleeding rates were .09, .08, .17, and .37 for > 20,000, 15-20,000, 10-15,000, and < 10,000/MUL mean platelet counts respectively (p = .003). Forty-four percent of patients were transferred back to the primary acute care service with infection being the most common reason for transfer. CONCLUSIONS: This study is the first to examine exercise related bleeding complications during acute inpatient rehabilitation in severely thrombocytopenic hematologic cancer patients. Bleeding rates increased with lower platelet counts. However, using the exercise guidelines for severely thrombocytopenic patients, the risk of severe exercise-related bleeding events was low.

AB - The authors describe a new sorbent for amitraz and teflubenzuron pesticides. It consists of a platinum wire coated with polypyrrole-coated ZnO nanorods. The nanocomposite was prepared by a two-step process. In the first step, oriented ZnO nanorods were hydrothermally grown in situ on a platinum wire. Subsequently, oxidative vapor phase polymerization of pyrrole was performed on FeCl3 impregnated ZnO nanorods to give a porous polypyrrole film. The organic/inorganic nanocomposite synthesized through hydrothermal deposition and chemical vapor deposition polymerization yields material with attractive properties. The coated wire was applied to solid-phase microextraction of amitraz (in the form of 2,4 dimethylaniline resulting from the hydrolysis of amitraz) and teflubenzuron. The effects of extraction temperature, extraction time, sample pH value and salt concentration were optimized. The analytes 2,4-dimethylaniline and teflubenzuron were then quantified by GC-MS. Under optimum conditions, the LODs range between 0.1 and 0.15 ng.mL-1. Relative standard deviations at two concentration are <8.3% for intraday precision and <10.3% for inter-day precision. In all cases, the fiber to fiber reproducibility is <12.2%. For both analytes the linear dynamic ranges are 0.5-300 ng.mL-1. The procedure was successfully applied to the analysis of spiked agricultural water samples. Graphical abstract A novel inorganic/organic hybrid nanocomposite was synthesized through in situ hydrothermal deposition of ZnO nanorods and ten placing a thin layer of polypyrrole on them by chemical vapor deposition polymerization. This nanocomposite was applied to fabricate a solid-phase microextraction fiber for the extraction of amitraz and teflubenzuron pesticides residue from agricultural samples prior to their quantitation by GC-MS.

AB - A homogeneous and enzyme-free fluorometric assay is described for the determination of microRNA-182. It is based on the use of DNA circuits and DNAzyme. The DNA circuits warrant strong signal amplification by virtue of catalytic hairpin assembly, a system that consists of two hairpin substrates. A part of the DNAzyme sequence is programmed to sequester into one of the two hairpin substrates. In the presence of target microRNA-182, the two hairpin substrates undergo catalytic assembling. This results in the formation of a DNA duplex and the release of the DNAzyme from the hairpin structure. Upon cyclic amplification, one target catalyzes the formation of Mg (II)-dependent DNAzymes. These bind to, and hydrolyze, the fluorescently labeled substrates for signal amplification and transduction. Based on nucleic acid programmability, this engineered assay has a limit of detection as low as 6.8 f. and a dynamic range that covers the 10 f. to10 nM microRNA-182 concentration range. Detection can be performed within 60 min. The assay is simple, rapid, homogenous, cost-effective, and enzyme-free. These features make the method an attractive tool in routine microRNA diagnosis and, conceivably, in point of care uses.

PMID- 29594493 TI - Reliability of HR-pQCT Derived Cortical Bone Structural Parameters When Using Uncorrected Instead of Corrected Automatically Generated Endocortical Contours in a Cross-Sectional Study: The Maastricht Study. AB - Most HR-pQCT studies examining cortical bone use an automatically generated endocortical contour (AUTO), which is manually corrected if it visually deviates from the apparent endocortical margin (semi-automatic method, S-AUTO). This technique may be prone to operator-related variability and is time consuming. We examined whether the AUTO instead of the S-AUTO method can be used for cortical bone analysis. Fifty scans of the distal radius and tibia from participants of The Maastricht Study were evaluated with AUTO, and subsequently with S-AUTO by three independent operators. AUTO cortical bone parameters were compared to the average parameters obtained by the three operators (S-AUTOmean). All differences in mean cortical bone parameters between AUTO and S-AUTOmean were < 5%, except for lower AUTO cortical porosity of the radius (- 16%) and tibia (- 6%), and cortical pore volume (Ct.Po.V) of the radius (- 7%). The ICC of S-AUTOmean and AUTO was > 0.90 for all parameters, except for cortical pore diameter of the radius (0.79) and tibia (0.74) and Ct.Po.V of the tibia (0.89), without systematic errors on the Bland-Altman plots. The precision errors (RMS-CV%) of the radius parameters between S-AUTOmean and AUTO were comparable to those between the individual operators, whereas the tibia RMS-CV% between S-AUTOmean and AUTO were higher than those of the individual operators. Comparison of the three operators revealed clear inter-operator variability. This study suggests that the AUTO method can be used for cortical bone analysis in a cross-sectional study, but that the absolute values-particularly of the porosity-related parameters-will be lower. PMID- 29594494 TI - Amperometric detection of microRNA based on DNA-controlled current of a molybdophosphate redox probe and amplification via hybridization chain reaction. AB - An electrochemical sensor is described for the determination of microRNA-21 by combing the DNA generated current with target-triggered hybridization chain reaction (HCR). A thiol-modified hairpin capture probe was first immobilized on a gold electrode. In the presence of microRNA-21, hybridization leads to a conformational change of the capture probe. The conformational change triggers HCR to generate a long DNA strand on the surface of the electrode. The phosphate backbone of the long DNA strand then reacts with molybdate to form the redox redox probe molybdophosphate, and this generates an electrochemical current. The HCR triggered by microRNA increases the amount of phosphate groups due to the extension of the DNA length, and thus increases the response current. The electrode, best operated at a voltage of 0.20 V, was successfully applied to the analysis of microRNA-21 in (spiked) human serum samples. In our perception, it represents a promising tool for analyzing a variety of microRNA biomarkers. Graphical abstract Electrochemical sensor for detection of microRNA-21 by combing the DNA generated electrochemical current concept with target-triggered hybridization chain reaction (HCR) strategy is reported. DNA strands (S1 and S2) were assembled onto electrode through HCR reaction. MCH: 6-mercapto-1-hexanol. PMID- 29594495 TI - Evaluation of sentinel lymph node biopsy prior to axillary lymph node dissection: the role of isolated tumor cells/micrometastases and multifocality/multicentricity-a retrospective study of 1214 breast cancer patients. AB - PURPOSE: Sentinel lymph node biopsy (SLNB) alone has thus become an accepted surgical approach for patients with limited axillary metastatic disease. We investigated to what extent isolated tumor cells (ITC) or micrometastasis in SLNBs is associated with proven tumor cells or metastasis in non-sentinel lymph nodes. Furthermore, we investigated the feasibility of SLNB in multifocal and multicentric tumors as both entities have been considered a contraindication for this technique. METHODS: 1214 women suffering from T1 and T2 invasive breast cancer, with clinically and sonographically insuspect axillary status and undergoing primary breast cancer surgery including SLNB and axillary staging in case of SLN (sentinel lymph node) metastases, were recruited into this multicentered study. RESULTS: ITC and micrometastases were found in 2.01 and 21.4% of patients with SLN metastases (n = 299). Among patients with sentinel micrometastases, 4.7% showed further axillary micrometastases, while only two patients (3.1%) had two axillary macrometastases. Multifocal and multicentric tumors were diagnosed in 9.3 and 2.6% of our patients who at least had one SLN resected, respectively. Detection rates of SLNs did not differ between the cohorts suffering from unicentric and multifocal or multicentric disease. Moreover, the portion of tumor-free SLNs, the number of SLNs with metastasis as well as the mean number of resected SLNs did not differ. CONCLUSIONS: No patient with sentinel node micrometastases showed more than two axillary macrometastases. Multifocal and multicentric disease is no contraindication for SLNB. PMID- 29594496 TI - pDHS-ELM: computational predictor for plant DNase I hypersensitive sites based on extreme learning machines. AB - DNase I hypersensitive sites (DHSs) are hallmarks of chromatin zones containing transcriptional regulatory elements, making them critical in understanding the regulatory mechanisms of gene expression. Although large amounts of DHSs in the plant genome have been identified by high-throughput techniques, current DHSs obtained from experimental methods cover only a fraction of plant species and cell processes. Furthermore, these experimental methods are both time-consuming and expensive. Hence, it is urgent to develop automated computational means to efficiently and accurately predict DHSs in the plant genome. Recently, several methods have been proposed to predict the DHSs. However, all these methods took a lot of time to build the model, making them inappropriate for data with massive volume. In the present work, a new ensemble extreme learning machine (ELM)-based model called pDHS-ELM was proposed to predict the DHSs in the plant genome by fusing two different modes of pseudo-nucleotide composition. Here, two kinds of features including reverse complement kmer and pseudo-nucleotide composition were used to represent the DHSs. The ELM model was used to build the base classifiers. Then, an ensemble framework was employed to combine the outputs of these base classifiers. When applied to DHSs in Arabidopsis thaliana and rice (Oryza sativa) genome, the proposed method could obtain accuracies up to 88.48 and 87.58%, respectively. Compared with the state-of-the-art techniques, pDHS-ELM achieved higher sensitivity, specificity, and Matthew's correlation coefficient with much less training and test time. By employing pDHS-ELM, we identified 42,370 and 103,979 DHSs in A. thaliana and rice genome, respectively. The predicted DHSs were depleted of bulk nucleosomes and were tightly associated with transcription factors. Approximately 90% of the predicted DHSs were overlapped with transcription factors. Meanwhile, we demonstrated that the predicted DHSs were also associated with DNA methylation, nucleosome positioning/occupancy, and histone modification. This result suggests that pDHS-ELM can be considered as a new promising and powerful tool for transcriptional regulatory elements analysis. Our pDHS-ELM tool is available from the following website https://github.com/shanxinzhang/pDHS-ELM/ .

AB - This paper reports on an electrochemical sensing system for L-cysteine. It is based on the use of hollow cubic Cu2O particles that were prepared in two steps. First, the Cu2O/ polystyrene (PS) composites were prepared by a surface ion exchange strategy for in-situ reductive deposition on the surface of carboxy capped PS particles. Thereafter, the PS particles were removed from the Cu2O/PS composites by treatment with tetrahydrofuran (THF). The resulting hollow cubic Cu2O particles were placed in a Nafion matrix on a glassy carbon electrode (GCE) which exhibits high surface area, good site accessibility and excellent electrocatalytic activity for L-cysteine. The cyclic voltammetric response of the modified GCE to L-cysteine is about 2.8-fold stronger than when using a GCE modified with pure Cu2O. The detection limit for L-cysteine is lower by about 1 order of magnitude, and the working voltage is rather low (-0.08 V vs. Ag/AgCl). An excellent electrochemical selectivity for L-cysteine over other amino acids was also achieved. The method was successfully applied to the determination of L cysteine in pharmaceutical samples. Graphical abstract An electrochemical sensing system for the detection of L-cysteine in amino acid injections has been established by using the hollow cubic Cu2O particles as recognition element.

AB - The functional relationship between arbuscular mycorrhizal fungi (AMF) and their hosts is variable on small spatial scales. Here, we hypothesized that herbivore exclusion changes the AMF community and alters the ability of AMF to enhance plant tolerance to grazing. We grew the perennial bunchgrass, Themeda triandra Forssk in inoculum from soils collected in the Kenya Long-term Exclosure Experiment where treatments representing different levels of herbivory have been in place since 1995. We assessed AMF diversity in the field, using terminal restriction fragment length polymorphism and compared fungal diversity among treatments. We conducted clipping experiments in the greenhouse and field and assessed regrowth. Plants inoculated with AMF from areas accessed by wild herbivores and cattle had greater biomass than non-inoculated controls, while plants inoculated with AMF from where large herbivores were excluded did not benefit from AMF in terms of biomass production. However, only the inoculation with AMF from areas with wild herbivores and no cattle had a positive effect on regrowth, relative to clipped plants grown without AMF. Similarly, in the field, regrowth of plants after clipping in areas with only native herbivores was higher than other treatments. Functional differences in AMF were evident despite little difference in AMF species richness or community composition. Our findings suggest that differences in large herbivore communities over nearly two decades has resulted in localized, functional changes in AMF communities. Our results add to the accumulating evidence that mycorrhizae are locally adapted and that functional differences can evolve within small geographical areas.

AB - A new kind of labelled antibody was synthesized by modifying gold nanoparticles (AuNPs) with the fluorophore rhodamine B isothiocyanate (RBITC) and a secondary antibody (IgG). The conjugate thus obtained was used in a competitive sandwich assay with a turn-on signal change. It was designed to detect the organophosphorus pesticide chlorpyrifos. The fluorescence of the RBITC-labeled gold immunoprobe with emission at 575 nm and excitation at 556 nm is almost completely quenched. If, however, cysteamine is added, the fluorophore is released from the labeled secondary antibody and fluorescence increases in accordance with the quantity of secondary antibody bound to the sandwich. This assay was applied to determine chlorpyrifos in dried tangerine peels. The detection results were also independently confirmed by LC-MS/MS. The method allows the concentrations of chlorpyrifos to be quantified down to 4.9 ng.mL-1, which is equivalent to 61 MUg.kg-1 in dried tangerine peels. In our perception, this approach has a wide potential to be applied in the determination of numerous analytes for which antibodies are available.

PMID- 29594501 TI - Mechanisms of Trabecular Formation and Specification During Cardiogenesis. AB - Trabecular morphogenesis is a key morphologic event during cardiogenesis and contributes to the formation of a competent ventricular wall. Lack of trabeculation results in embryonic lethality. The trabecular morphogenesis is a multistep process that includes, but is not limited to, trabecular initiation, proliferation/growth, specification, and compaction. Although a number of signaling molecules have been implicated in regulating trabeculation, the cellular processes underlying mammalian trabecular formation are not fully understood. Recent works show that the myocardium displays polarity, and oriented cell division (OCD) and directional migration of the cardiomyocytes in the monolayer myocardium are required for trabecular initiation and formation. Furthermore, perpendicular OCD is an extrinsic asymmetric cell division that contributes to trabecular specification, and is a mechanism that causes the trabecular cardiomyocytes to be distinct from the cardiomyocytes in compact zone. Once the coronary vasculature system starts to function in the embryonic heart, the trabeculae will coalesce with the compact zone to thicken the heart wall, and abnormal compaction will lead to left ventricular non-compaction (LVNC) and heart failure. There are many reviews about compaction and LVNC. In this review, we will focus on the roles of myocardial polarity and OCD in trabecular initiation, formation, and specification. PMID- 29594503 TI - Hyperphosphatemic tumoral calcinosis caused by FGF23 compound heterozygous mutations: what are the therapeutic options for a better control of phosphatemia? AB - BACKGROUND: Hyperphosphatemic familial tumoral calcinosis (HFTC) is a rare autosomal recessive disease caused by mutations in genes encoding FGF23 or its regulators, and leading to functional deficiency or resistance to fibroblast growth factor 23 (FGF23). Subsequent biochemical features include hyperphosphatemia due to increased renal phosphate reabsorption, and increased or inappropriately normal 1,25-dihydroxyvitamin D (1,25-D) levels. CASE DIAGNOSIS/TREATMENT: A 15-year-old girl was referred for a 1.2-kg-calcified mass of the thigh, with hyperphosphatemia (2.8 mmol/L); vascular impairment and soft tissue calcifications were already present. DNA sequencing identified compound heterozygous mutations in the FGF23 gene. Management with phosphate dietary restriction, phosphate binders (sevelamer, aluminum, nicotinamide), and acetazolamide moderately decreased serum phosphate levels; oral ketoconazole was secondary administered, leading to significantly decreased 1,25-D levels albeit only moderate additionally decreased phosphate levels. However, therapeutic compliance was questionable. Serum phosphate levels always remained far above the upper normal limit for age. The patient presented with two relapses of the thigh mass, requiring further surgery. CONCLUSIONS: We suggest that control of phosphate metabolism is crucial to prevent recurrences and vascular complications in HFTC; however, the medical management remains challenging. PMID- 29594502 TI - Fates Aligned: Origins and Mechanisms of Ventricular Conduction System and Ventricular Wall Development. AB - The cardiac conduction system is a network of distinct cell types necessary for the coordinated contraction of the cardiac chambers. The distal portion, known as the ventricular conduction system, allows for the rapid transmission of impulses from the atrio-ventricular node to the ventricular myocardium and plays a central role in cardiac function as well as disease when perturbed. Notably, its patterning during embryogenesis is intimately linked to that of ventricular wall formation, including trabeculation and compaction. Here, we review our current understanding of the underlying mechanisms responsible for the development and maturation of these interdependent processes. PMID- 29594504 TI - Management of high blood pressure in children: similarities and differences between US and European guidelines. AB - Over the last several decades, many seminal longitudinal cohort studies have clearly shown that the antecedents to adult disease have their origins in childhood. Hypertension (HTN), which has become increasingly prevalent in childhood, represents one of the most important risk factors for cardiovascular diseases (CVD) such as heart disease and stroke. With the risk of adult HTN much greater when HTN is manifest in childhood, the future burden of CVD worldwide is therefore concerning. In an effort to slow the current trajectory, professional societies have called for more rigorous, evidence-based guideline development to aid primary care providers and subspecialists in improving recognition, diagnosis, evaluation, and treatment of pediatric HTN. In 2016 the European Society of Hypertension and in 2017 the American Academy of Pediatrics published updated guidelines for prevention and management of high blood pressure (BP) in children. While there are many similarities between the two guidelines, important differences exist. These differences, along with the identified knowledge gaps in each, will hopefully spur clinical researchers to action. This review highlights some of these similarities and differences, focusing on several of the more important facets regarding prevalence, prevention, diagnosis, management, and treatment of childhood HTN. PMID- 29594505 TI - Urinary stone risk factors in the descendants of patients with kidney stone disease. AB - BACKGROUND: Evidence has indicated that immediate family members of nephrolithiasis patients had high opportunity to develop stones. However, they are usually not regarded to be at risk, since it is unclear if there are any lithogenic abnormalities found in non-stone-forming nephrolithiasis relatives. Our aim was to investigate urinary metabolic abnormalities in the children of nephrolithiasis patients, compared with the general population. METHODS: The 24-h urinary metabolic profile was studied for 28 calcium oxalate nephrolithiasis patients (NL) and 46 of their descendants (ND), as well as 40 non-stone-forming volunteers (V) and 34 of their descendants (VD). RESULTS: There was no difference between age, gender, and serum creatinine between NL vs. V (parental groups) and ND vs. VD (descendant groups). High urinary oxalate in nephrolithiasis and urinary calcium in their descendants was detected. In addition, an elevated urinary excretion rate of calcium, phosphate, protein, and albumin, along with low citrate excretion and high urinary supersaturation was observed in both the nephrolithiasis patients and their descendants. Approximate 17.8-24.4% of the nephrolithiasis descendants had a urinary supersaturation higher than the nephrolithiasis level, but none was found in VD group. The level of urinary supersaturation index was correlated with urinary protein and albumin excretion in nephrolithiasis family. CONCLUSION: It was demonstrated that nephrolithiasis offspring carried several urinary metabolic risks predisposing to stone formation which are similar to their parents, and about one in every five nephrolithiasis children had nephrolithiasis level urinary supersaturation. PMID- 29594506 TI - Obesity causes poorer clinical results and higher re-tear rates in rotator cuff repair. AB - BACKGROUND: The purpose of this retrospective study was to report on the functional outcome after both open and arthroscopic rotator cuff (RC) repair in normal weight, pre-obese and obese patients. It was hypothesized that obesity is a negative prognostic factor for clinical outcome and failure for the RC repair. METHODS: One hundred and forty-six patients who underwent either open or arthroscopic rotator cuff repair between 2006 and 2010 were included in this study. Seventy-five patients (56.7 +/- 10.1 years of age) after open RC repair and 71 patients (59.0 +/- 9.1 years of age) treated arthroscopically were available for evaluation. In both groups a double-row reconstruction was performed. Patients were divided in three groups according to their body-mass index. The mean follow-up was at 43 +/- 16 (minimum 24) months. At follow-up, the clinical outcome was assessed by the DASH and Constant score. An ultrasound of both shoulders was performed in all patients. RESULTS: The mean BMI was 28.3 +/- 5.3 in the arthroscopic group and 27.7 +/- 4.3 in the open group. Overall, in both groups similar clinical results were noted [Constant-Murley score 78.3 +/- 18.2 arthroscopic vs. 77.0 +/- 21.8 for open surgery; DASH 12.7 +/- 18.2 arthroscopic vs. 15.6 +/- 21.6 for open surgery (p = 0.81)]. Both the failure rate and the clinical outcome were significantly worse for obese patients (BMI > 30, p = 0.007). The failure rate was 15.8% for the normal-weight patients, 8.2% in the pre-obese group and in the obese group 28.6%. The RC repair failure occurred in 11 cases in both groups after arthroscopic or open treatment (15.0%). CONCLUSIONS: Both the arthroscopic and the open approach showed equivalent clinical results and failure rates. Obesity (BMI > 30) causes less favorable results in the Constant and DASH scores and showed higher re-tear rates. PMID- 29594507 TI - Graft extrusion after medial and lateral MAT differs according to surgical technique: a meta-analysis. AB - INTRODUCTION: It is unclear whether the incidence and amount of graft extrusion differ between knees undergoing medial and lateral meniscus allograft transplantation (MAT). This meta-analysis, therefore, compared the incidence and amount of transplanted meniscus allograft extrusion following medial and lateral MAT. MATERIALS AND METHODS: All studies comparing absolute or relative extrusions, or proportion of major extrusions (> 3 mm), on magnetic resonance imaging between medial and lateral MATs were included. RESULTS: Eight studies were included in the meta-analysis. Using the arthroscopic-assisted technique, medial MAT had significantly greater absolute (0.99 mm, p = 0.002) and relative (19.4%, p = 0.001) extrusions than lateral MAT. Using the complete arthroscopic technique, lateral MAT had 1.45 mm greater absolute extrusion than medial MAT (p < 0.001), but there was no difference in relative extrusion. Using the arthroscopic-assisted technique, the proportion of knees with major extrusion was greater for medial than lateral MAT (OR 5.32, p < 0.001), but, using the complete arthroscopic procedure, there was no difference in proportions of major extrusions between medial and lateral MAT (OR 0.28, p = 0.08). CONCLUSION: Graft extrusions after medial and lateral MAT differed according to surgical technique. Graft extrusion was greater after medial than lateral MAT using the arthroscopic assisted technique, but was greater after lateral than medial MAT using the complete arthroscopic procedure. LEVEL OF EVIDENCE: Meta-analysis (Level II). PMID- 29594508 TI - Wireless electrochemical preparation of gradient nanoclusters consisting of copper(II), stearic acid and montmorillonite on a copper wire for headspace in tube microextraction of chlorobenzenes. AB - This work introduces a new gradient fiber coating for microextraction of chlorobenzenes. Nanoclusters of organoclay-Cu(II) on a copper wire were fabricated by wireless electrofunctionalization. The resultant gradient coatings are more robust, and thermally and mechanically stable. Wireless electrofunctionalization was carried out in a bipolar cell under a constant deposition potential and using an ethanolic electrolyte solution containing stearic acid and montmorillonite. Stearic acid acts as an inexpensive and green coating while montmorillonite acts as a modifier to impart thermal stability. The gradient morphology of the nanoclusters was investigated by scanning electron microscopy, thermogravimetric analysis and energy dispersive X-ray spectroscopy. The coated wire was placed in a hollow needle and used for headspace in-tube microextraction (HS-ITME) of chlorobenzenes (CBs). Effects of various parameters affecting synthesis and extraction were optimized. Following extraction, the needles were directly inserted into the GC injector, and the CBs (chlorobenzene, 1,4-dichlorobenzene, 1,2-dichlorobenzene, 1,2,4-trichlorobenzene, 1,2,3,4 tetrachlorobenzene) were quantified by GC-MS. The limits of detection under optimized conditions range from 0.5 to 10 ng.L-1. The intra- and inter-day relative standard deviations (RSDs) (for n = 10, 5 respectively) using a single fiber are 6-10 and 10-15%, respectively. The fiber-to-fiber RSDs (for n = 3) is between 17 and 24%. The method was successfully applied to the extraction of CBs from real water samples, and relative recoveries are between 91 and 110%. Graphical abstract A gradient coating of organoclay-Cu nanoclusters was fabricated on a copper wire by wireless electrofunctionalization. The oxidation of copper takes place at the anodic pole (red) while dissolved oxygen in ethanol solution is reduced at the cathodic pole (blue). PMID- 29594509 TI - Exertional heat illness incidence and on-site medical team preparedness in warm weather. AB - To investigate the influence of estimated wet bulb globe temperature (WBGT) and the International Institute of Race Medicine (IIRM) activity modification guidelines on the incidence of exertional heat stroke (EHS) and heat exhaustion (HEx) and the ability of an on-site medical team to treat those afflicted. Medical records of EHS and HEx patients over a 17-year period from the New Balance Falmouth Road Race were examined. Climatologic data from nearby weather stations were obtained to calculate WBGT with the Australian Bureau of Meteorology (WBGTA) and Liljegren (WBGTL) models. Incidence rate (IR) of EHS, HEx, and combined total of EHS and HEx (COM) were calculated, and linear regression analyses were performed to assess the relationship between IR and WBGTA or WBGTL. One-way ANOVA was performed to compare differences in EHS, HEx, and COM incidence to four alert levels in the IIRM guidelines. Incidence of EHS, HEx, and COM was 2.12, 0.98, and 3.10 cases per 1000 finishers. WBGTA explained 48, 4, and 46% of the variance in EHS, HEx, and COM IR; WBGTL explained 63, 13, and 69% of the variance in EHS, HEx, and COM IR. Main effect of WBGTA and WBGTL on the alert levels were observed in EHS and COM IR (p < 0.05). The cumulative number of EHS patients treated did not exceed the number of cold water immersion tubs available to treat them. EHS IR increased as WBGT and IIRM alert level increased, indicating the need for appropriate risk mitigation strategies and on site medical treatment.

AB - This work evaluates the potential of methacrylate monoliths with multi-walled carbon nanotubes incorporated into the polymeric network for the extraction of antidepressants from human urine. The method is based on a micropipette solid phase extraction tip containing a hybrid monolithic material covalently attached to the polypropylene housing. A polymer layer made from poly(ethylene dimethacrylate) was bound to the inner surface of a polypropylene tip via UV grafting. The preparation of the monolith and the microextraction steps were optimized in terms of adsorption capacity. Limits of detection ranged from 9 to 15 MUg.L-1. The average precision of the method varied between 3 and 5% (intra tips), and from 4 to 14% (inter-tips). The accuracy of the method was evaluated through a recovery study by using spiked samples. Graphical abstract Hybrid polymer monoliths containing multi-walled carbon nanotubes (MWCNTs) were prepared in pipette tips by photo-polymerization approach. The extraction devices were used for the extraction of antidepressants in urine samples.

AB - Upconverting nanoparticles (UCNPs) are attractive reporters in immunoassays because of their outstanding detectability. However, non-specific binding of antibody-UCNP conjugates on protein coated solid support results in background, which limits the immunoassay sensitivity. Thus, the full potential of UCNPs as reporters cannot be fully exploited. The authors report here a method to improve the sensitivity of UCNP-based immunoassays by reducing the non-specific binding of antibody-UNCP conjugates on the protein coated solid support. In the assays studied here, poly(acrylic acid) (PAA) coated NaYF4:Yb3+,Er3+ type UCNPs were conjugated to two different antibodies against cardiac troponin I (cTnI) and thyroid stimulating hormone (TSH). The two-step heterogeneous sandwich immunoassays were performed in microtitration wells, and the green luminescence of antibody-UCNP conjugates was measured at 540 nm upon 980 nm excitation. Non specific binding of antibody-UCNP conjugates was reduced by mixing free PAA with PAA coated UCNPs before adding the UCNPs to the wells. The free PAA in the buffer reduced the background in both cTnI and TSH immunoassays (compared to the control assay without free PAA). The limits of detection decreased from 2.1 ng.L-1 to 0.48 ng.L-1 in case of cTnI and from 0.070 mIU.L-1 to 0.020 mIU.L-1 in case of TSH if PAA is added to the buffer. Presumably, the effect of free PAA is due to blocking of the surface areas where PAA coated UCNP would bind proteins non specifically. The method introduced here is likely to be applicable to other kinds of PAA-coated nanoparticles, and similar approaches conceivably work also with other nanoparticle coatings. Graphical abstract The presence of free poly(acrylic acid) (PAA) in a buffer solution prevents aggregation and non specific protein binding of PAA-coated upconverting nanoparticles (UCNPs) in heterogeneous sandwich immunoassays. The decrease in non-specific binding enables distinctly more sensitive assays to be performed.

AB - A method is described for the preparation of a nanocomposite material consisting of cuprous oxide/polyaniline/reduced graphene oxide (Cu2O/PANI/rGO). Aniline was employed as both the precursor for PANI and the reducing agent for Cu2+ and graphene oxide. A glassy carbon electrode was modified with the nanocomposite material. Chronoamperometric studies with the modified electrode showed it to enable an efficient electroreduction of hydrogen peroxide at -0.2 V vs. saturated calomel electrode.

AB - A sensing device was constructed for the amperometric determination of nitrite. It is based on the use of titanium dioxide (TiO2) nanotubes template with natural fibers and carrying hemin acting as the electron mediator. A glassy carbon electrode (GCE) was modified with the hemin/TNT nanocomposite. The electrochemical response to nitrite was characterized by impedance spectroscopy and cyclic voltammetry. An amperometric study, performed at a working potential of + 0.75 V (vs. Ag/AgCl), showed the sensor to enable determination of nitrite with a linear response in the 0.6 to 130 MUM concentration range and with a 59 nM limit of detection. Corresponding studies by differential study voltammetry (Ep = 0.75 V) exhibited a linear range from 0.6 * 10-6 to 7.3 * 10-5 M with a limit of detection of 84 nM. The sensing device was applied to the determination of nitrite in spiked tap and lake water samples. Graphical abstract Natural fibers templated synthesis of TNT immobilized hemin as electron transfer mediator for quantitative detection of nitrite with detection limit of 59 nM and good electrochemical sensitivity and the method can be used for quantitative determination of nitrite in water samples.

AB - Eukaryotic genomes are organized into chromatin, divided into structurally and functionally distinct euchromatin and heterochromatin compartments. The high level of compaction and the abundance of repeated sequences in heterochromatin pose multiple challenges for the maintenance of genome stability. Cells have evolved sophisticated and highly controlled mechanisms to overcome these constraints. Here, we summarize recent findings on how the heterochromatic state influences DNA damage formation, signaling, and repair. By focusing on distinct heterochromatin domains in different eukaryotic species, we highlight the heterochromatin contribution to the compartmentalization of DNA damage repair in the cell nucleus and to the repair pathway choice. We also describe the diverse chromatin alterations associated with the DNA damage response in heterochromatin domains and present our current understanding of their regulatory mechanisms. Finally, we discuss the biological significance and the evolutionary conservation of these processes.

AB - A highly selective method is described for the colorimetric determination of Au(III) ions in acidic solution using gold nanoparticles (AuNPs) functionalized with thiolated methoxy poly(ethylene glycol) (mPEG). The presence of Au(III) induces the aggregation of the PEG-AuNPs, and this is accompanied by a color change from wine red to blue, and a decrease in absorbance at 525 nm. This can be monitored spectrophotometrically and visually. Absorbance at 525 nm linearly drops in the 0.50 to 1.75 mg.L-1 Au(III) concentration range, with a 0.25 mg.L-1 detection limit. The method is surprisingly selective over other metal ions. It was successfully applied to the analysis of ore samples. Graphical Abstract ?.

AB - The authors have synthesized molybdenum disulfide nanosheets (MoS2 nanosheets) by using a bottom-up hydrothermal method. The nanosheets display strong catalytic (enzyme mimetic) activity in catalyzing the oxidation of peroxidase substrate of 3,3',5,5'-tetramethylbenzidine (TMB) in presence of H2O2 to produce a blue product. The peroxidase mimicking properties of MoS2 nanosheets depend on temperature, H2O2 concentration and pH value. A choline assay was worked out where choline was oxidized by choline oxidase in presence of oxygen to produce H2O2 which is colorimetrically detected, best at 652 nm. The method works in the 1 to 180 MUM choline concentration range with a 0.4 MUM detection limit. Color changes may also be detected visually. The assay is simple, highly sensitive, selective and rapid. It was applied in the determination of choline in (spiked) milk and serum.

PMID- 29594519 TI - Electrochemical prostate specific antigen aptasensor based on hemin functionalized graphene-conjugated palladium nanocomposites. AB - An electrochemical aptasensor is described for the detection of prostate specific antigen (PSA). The aptasensor is based on the use of hemin-functionalized graphene-conjugated palladium nanoparticles (H-Gr/PdNPs) deposited on a glassy carbon electrode. The nanocomposites integrate the high electrical conductivity of graphene with the easily functionalized surface chemistry of PdNPs and their excellent catalytic property. The hemin placed on graphene acts as both a protective agent and an in-situ redox probe. The PdNPs provide numerous binding sites for the immobilization of DNA-biotin via coordinative binding between Pd and amino groups. A sensitive and specific PSA assay was attained by immobilizing the PSA aptamer via biotin-streptavidin interaction. The resulting aptasensor has a linear response that covers the PSA concentration range from 0.025 to 205 ng.mL 1, with a 8 pg.mL-1 lower detection limit (at -0.362 V, scan rate: 0.1 mV.s-1, S/N = 3). The method was applied to the quantitation of PSA in spiked serum samples, giving recoveries ranging from 95.0 to 100.3%. Graphical abstract A signal amplified and approving electrochemical aptasensor was constructed for the determination of prostate specific antigen (PSA) based on the use of hemin functionalized graphene conjugated to palladium nanoparticles (H-Gr/PdNPs). The sensor has a wide linear range, a relatively low detection limit, satisfying stability and high specificity. PMID- 29594520 TI - Highly sensitive and selective determination of copper(II) based on a dual catalytic effect and by using silicon nanoparticles as a fluorescent probe. AB - The authors describe a silicon nanoparticle-based fluorometric method for sensitive and selective detection of Cu2+. It is based on the catalytic action of Cu2+ on the oxidation of cysteine (Cys) by oxygen to form cystine and the by product H2O2. The generated H2O2 is catalytically decomposed by Cu2+ to generate hydroxyl radicals which oxidize and destroy the surface of SiNPs. As a result, the blue fluorescence of the SiNPs is quenched. The method has excellent selectivity due to the dual catalytic effects of Cu2+, which is much better than most previously reported nanomaterial-based assays for Cu2+. Under the optimal conditions, the method has low detection limit (29 nM) and a linear response in a concentration range from 0.05 MUM to 15 MUM. The method has been successfully applied to the determination of Cu2+ in spiked real water samples, and the results agreed well with those obtained by the Chinese National Standard method (GB/T 7475-1987; AAS). Graphical abstract Schematic presentation of a fluorometric method for the determination of Cu2+ based on the dual catalytic effects of Cu2+, and the oxidative effect of hydroxy radicals on the surface of silicon nanoparticles (SiNPs). The method has a 29 nM detection limit and good selectivity. PMID- 29594521 TI - Cortical neural arousal is differentially affected by type of physical exercise performed. AB - Critical flicker frequency (CFF) threshold is a visual discrimination task designed to assess cortical neural arousal, where higher values are associated with increased information processing and improved cognitive function. Previous studies using CFF assessments before and after exercise have only used one type of exercise (e.g., short, fatiguing, steady state, time to exhaustion, etc.). Therefore, the purpose of this study was to determine the effect of exercise type and intensity on neural arousal. 22 recreational runners (10 men, 12 women; age 25 +/- 6 years) volunteered to participate in the study. They completed a VO2max test (short, fatiguing trial), and three 30-min treadmill runs (longer, steady state trials) at rating of perceived exertion (RPE) levels of 13, 15, and 17. Before and after each exercise test, subjects were asked to complete the CFF test; Mtot and Mdi were calculated, which are the average and difference of the ascending/descending frequency trials, respectively. There were no main effects found for either intensity (p = 0.641) or time (p = 0.283); there was, however, a significant interaction found (intensity*time; p = 0.001). In the VO2max test and in the longer, steady-state runs at RPE13 and 15, there was no change in Mtot. There was a significant increase in Mtot after the run at RPE17 (p = 0.019). For Mdi, the VO2max test elicited a significant decrease (p = 0.005), but there was no change after the steady-state runs. The results suggest that short, fatiguing and longer, steady-state exercise affect cortical neural arousal differently. Increases in arousal, and perhaps the related domain of information processing, are more likely to come from steady-state exercise at a vigorous intensity. PMID- 29594522 TI - Turn-on fluorometric and colorimetric probe for hydrogen peroxide based on the in situ formation of silver ions from a composite made from N-doped carbon quantum dots and silver nanoparticles. AB - The authors describe a fluorometric and colorimetric nanoprobe for H2O2. The detection scheme is based on the in-situ formation of silver(I) ions from a composite consisting of nitrogen-doped carbon quantum dots (N-CQDs) and silver nanoparticles (AgNPs). A drastic change occurs both in fluorescence and color of the solution of the N-CQD/AgNPs composite. The fluorescence of composite (with excitation/emission peaking at 320/384 nm) is enhanced on increasing the concentration of H2O2 due to the oxidation of silver metal in the N-CQD/AgNPs to form Ag(I) ions. The latter undergo strong coordination with the nitrogen atoms of the N-CQDs. In-situ formation of Ag(I) ions further results in a change in color of the solution from pale yellow (with a peak at 408 nm) to colorless. Under optimized conditions, the probe gives a fluorometric and colorimetric response in the 10 to 50 MUM H2O2 concentration range with a 4.7 MUM limit of detection. The probe is highly selective over several potentially interfering ions and agents. It was successfully applied to the determination of H2O2 in spiked samples without prior treatment. Graphical abstract Graphical presentation for specific detection of H2O2 based on the in-situ formation of Ag(I) ions from a composite consisting of silver nanoparticles and nitrogen-doped carbon quantum dots. PMID- 29594523 TI - Red emitting and highly stable carbon dots with dual response to pH values and ferric ions. AB - The authors describe strongly red-emitting carbon dots (CDs) which were obtained via microwave synthesis using phenylenediamine as the carbon source. The structural and optical properties of the resultant CDs are studied in some detail. The CDs possess (a) longwave emission (peaking at 620 nm under 470 nm excitation), (b) a quantum yield of ~15%, (c) a size of typically 3.8 nm; and (d) good photostability. The CDs have a pH-dependet response that covers the pH 5 to 10 range, and their fluorescence is quenched by ferric ions. The CDs can detect ferric ions in aqueous samples in the 0 to 30 MUM concentration range with a lower detection limit of 15 nM. The CDs were also used to image pH values and ferric ions in E. coli bacteria. Graphical abstract The red-emitting carbon dots with high stability are synthesized which show dual response to pH-values and ferric ions in aqueous solution and biological media simultaneously. PMID- 29594524 TI - Silicon nanoparticles coated with an epitope-imprinted polymer for fluorometric determination of cytochrome c. AB - The authors describe a composite consisting of silicon nanoparticles that were first coated with SiO2 and then with a molecularly imprinted polymer (SiNP@SiO2@MIP). The MIP was generated by dual epitope imprinting such that it can recognize cytochrome c (Cyt c). The MIP on the NPs was prepared from the functional monomer zinc(II) acrylate (ZnA), the crosslinker ethylene glycol dimethacrylate and the initiator 2,2'-azoisobutyronitrile. Dual epitope templates for Cyt c included (a) a C-terminal nonapeptide (AYLKKATNE), and (b) an N terminal nonapeptide (GDVEKGKKI). The chelation between Zn(II) of ZnA and the amino groups or hydroxy groups of the template nonapeptides warrants good recognition and capture of Cyt c. The fluorescence originating from SiNPs has excitation/emission peaks at 360/480 nm and is quenched by Cyt c in the 0.50-40.0 MUM concentration range. The correlation coefficient for the calibration plot of the imprinted NPs is 0.9937. The detection limit is 0.32 +/- 0.01 MUM, the precisions of six replicate detections at levels of 0.5, 20 and 40 MUM Cyt c are 3.2, 2.7 and 2.8%, respectively, and the imprinting factor is 2.43. Compared to single epitope template imprinting, dual epitope imprinting results in improved selectivity. The imprinted nanoparticles can discriminate Cyt c even if one amino acid is mismatched. The method was applied to the determination of Cyt c in spiked diluted human serum and gave recoveries between 94.0 and 107.5%. Graphical Abstract A fluorescent material of the architecture silicon nanoparticle@SiO2@molecularly imprinted polymer (SiNP@SiO2@MIP) was fabricated by dual epitope imprinting and a metal-chelating method. The chelation between Zn(II) of the functional monomer zinc(II) acrylate and the amino groups or hydroxy groups of template warrants that the material recognizes and captures cytochrome c well, and this results in fluorescence quenching.

AB - An immunohistochemical method is described to visualize the distribution of metallothioneins 1/2 (MT 1/2) and metallothionein 3 (MT 3) in human ocular tissue. It is making use of (a) antibodies conjugated to gold nanoclusters (AuNCs) acting as labels, and (b) laser ablation (LA) coupled to inductively coupled plasma - mass spectrometry (ICP-MS). Water-soluble fluorescent AuNCs (with an average size of 2.7 nm) were synthesized and then conjugated to antibody by carbodiimide coupling. The surface of the modified AuNCs was then blocked with hydroxylamine to avoid nonspecific interactions with biological tissue. Immunoassays for MT 1/2 and MT 3 in ocular tissue sections (5 MUm thick) from two post mortem human donors were performed. Imaging studies were then performed by fluorescence using confocal microscopy, and LA-ICP-MS was performed in the retina to measure the signal for gold. Signal amplification by the >500 gold atoms in each nanocluster allowed the antigens (MT 1/2 and MT 3) to be imaged by LA-ICP-MS using a laser spot size as small as 4 MUm. The image patterns found in retina are in good agreement with those obtained by conventional fluorescence immunohistochemistry which was used as an established reference method. Graphical abstract Gold nanoclusters (AuNCs) conjugated to a primary specific antibody serve as a label for amplified bioimaging of metallothioneins (MTs) by laser ablation coupled to inductively coupled plasma - mass spectrometry (ICP-MS) in human ocular tissue sections. PMID- 29594526 TI - Nanodiamonds conjugated to gold nanoparticles for colorimetric detection of clenbuterol and chromium(III) in urine. AB - Nanodiamonds were modified such that they carry thiol groups (ND-thiol). Gold nanoparticles were reacted with ND-thiol to obtain a highly stable conjugate of the type ND@AuNPs. Both ND-thiol and the ND@AuNPs were characterized by SEM, TEM, AFM, DLS, zeta potential, XPS, XRD, UV-Vis, Raman, FTIR and cytotoxicity studies. Their biocompatibility was confirmed via an MTT assay with HeLa cells. At a pH value of 6, the ND@AuNPs represent a colorimetric probe that can be used to selectively detect the illegally used beta-adrenergic drug clenbuterol (CLB) and the pollutant chromium(III). Detection can be performed visually by monitoring the color change from wine red to purple blue, or by colorimetric measurement of the so-called SPR peaks at 651 and 710 nm. The color changes are due to aggregation, and this is confirmed by TEM and DLS data. The involvement of surface functional groups that assist in analyte recognition was verified by FTIR. The detection limits are 0.49 nM for CLB, and 0.37 nM for Cr(III). The ND@AuNPs were successfully applied to the determination of Cr(III) and CLB in spiked human urine samples. Notably, the low interference by other ions in the detection of Cr(III) in tap and lake water is confirmed by ICP-MS analyses. Graphical abstract Nanodiamonds carrying thiol groups (ND-Thiol) were conjugated to gold nanoparticles, and the resulting ND@AuNPs are shown to be viable probes for the colorimetric detection of sub-nanomolar levels of clenbuterol (CLB) and Cr(III) ions, with demonstrated applicability to real water and urine samples. PMID- 29594527 TI - Matched cohort study of topical tranexamic acid in cementless primary total hip replacement. AB - PURPOSE: Tranexamic acid has been shown to be effective in reducing blood loss after total hip replacement. The purpose of this study was to prospectively assess the effectiveness of topical TXA use to reduce blood loss after primary total hip replacement and to compare these outcomes with those of a matched control group from a similar cohort that did not have received tranexamic acid. METHODS: This is a prospective matched control study to assess the effect of a 2 g topical tranexamic acid in 50 mL physiological saline solution in total hip replacement. Primary outcomes were hemoglobin and hematocrit drop, and total blood loss. Secondary outcomes were transfusion rates, length of hospital stay, deep vein thrombosis, and pulmonary embolism events. RESULTS: We could match 100 patients to a control group. There were no statistical significantly differences between the two groups. The hemoglobin and hematocrit postoperative values were significantly higher in topical tranexamic acid group than in control group (P < 0.001). The mean total blood loss was 769 in topical tranexamic acid group and 1163 in control group with significant differences (P = 0.001), which meant 34% reduction in total blood loss. Length of stay was lower in topical tranexamic acid group. The risk of deep vein thrombosis and pulmonary events did not increase. CONCLUSIONS: A single dose of 2 g tranexamic acid in 50 mL physiological saline solution topical administration was effective and safe in reducing bleeding in patients undergoing unilateral primary non-cemented total hip replacement compared to a matched control group. PMID- 29594528 TI - Comparing the efficacy of intravenous or intra-articular tranexamic acid in reducing blood loss in simultaneous bilateral knee replacement surgery without the use of tourniquet. AB - PURPOSE: To compare the effect of intravenous or intra-articular route of administration of tranexamic acid in reducing the blood loss in simultaneous bilateral total knee replacement surgeries performed without the use of tourniquets. METHODS: Prospective cohort study of 30 consecutive patients grouped into two groups; Group 1: intravenous group and group 2: intra-articular group. Two outcome measures were studied; mean drop in post-operative haemoglobin and need for blood transfusion in both groups. RESULTS: No significant difference in mean drop of haemoglobin and need for blood transfusion in both groups. CONCLUSION: Route of administration of tranexamic acid does not influence on the mean drop of haemoglobin and need for blood transfusion in simultaneous bilateral total knee replacement surgeries performed without the use of tourniquet. PMID- 29594529 TI - Ferutinin Induces Membrane Depolarization, Permeability Transition Pore Formation, and Respiration Uncoupling in Isolated Rat Liver Mitochondria by Stimulation of Ca2+-Permeability. AB - It is well known that the terpenoid ferutinin (4-oxy-6-(4-oxybenzoyloxy) dauc-8,9 en), isolated from the plant Ferula tenuisecta, considerably increases the permeability of artificial and cellular membranes to Ca2+-ions and produces apoptotic cell death in different cell lines in a mitochondria-dependent manner. The present study was designed for further evaluation of the mechanism(s) of mitochondrial effects of ferutinin using isolated rat liver mitochondria. Our findings provide evidence for ferutinin at concentrations of 5-27 uM to decrease state 3 respiration and the acceptor control ratio in the case of glutamate/malate as substrates. Ferutinin alone (10-60 uM) also dose-dependently dissipated membrane potential. In the presence of Ca2+-ions, ferutinin (10-60 uM) induced considerable depolarization of the inner mitochondrial membrane, which was partially inhibited by EGTA, and permeability transition pore formation, which was diminished partly by cyclosporin A, and did not influence markedly the effect of Ca2+ on mitochondrial respiration. Ruthenium Red, a specific inhibitor of mitochondrial calcium uniporter, completely inhibited Ca2+-induced mitochondria swelling and membrane depolarization, but did not affect markedly the stimulation of these Ca2+-dependent processes by ferutinin. We concluded that the mitochondrial effects of ferutinin might be primarily induced by stimulation of mitochondrial membrane Ca2+-permeability, but other mechanisms, such as driving of univalent cations, might be involved. PMID- 29594530 TI - Parental awareness of testicular torsion amongst Irish parents. AB - PURPOSE: Testicular torsion is the most concerning underlying cause of acute scrotal pain that can lead to loss of the affected testicle. Whether a torted testicle can be salvaged surgically is directly affected by prompt presentation and diagnosis. This study aims to evaluate the awareness of testicular torsion amongst Irish parents and evaluate their response to a potential torsion. METHODS: An anonymous questionnaire was distributed to parents attending general paediatric clinics and an acute paediatric unit in two paediatric tertiary referral centres. SPSS statistical analysis software was used to perform multivariant analysis of the data. RESULTS: There were 242 completed surveys. Fifty-six percent of responders had an awareness of torsion. In the event of an episode of severe testicular pain parents who were aware of testicular torsion were 4 times more likely to present immediately than those who had no awareness of torsion (OR 4.2, 95% CI 1.4-12.2, P < 0.01), and those who identified correctly the critical timeframe were 3 times more likely to present immediately than those who did not (OR 3.0, 95% CI 0.85-10.8, P = 0.08). Of those parents with boys only 11% had discussed what to do in the event of acute scrotal pain. CONCLUSIONS: Education of this topic to the general Irish population and in particular to parents and young males is not established. Both knowledge of testicular torsion and awareness of the urgency in presentation are factors that determine parents promptness in seeking medical attention for their child in the setting of acute scrotal pain. PMID- 29594531 TI - Determination of subnanomolar levels of mercury (II) by using a graphite paste electrode modified with MWCNTs and Hg(II)-imprinted polymer nanoparticles. AB - Mercury ion-imprinted polymer nanoparticles (Hg-IP-NPs) were synthesized via precipitation polymerization by using itaconic acid as a functional monomer. A carbon paste electrode was impregnated with the synthesized Hg-IP-NPs and MWCNTs to obtain a highly sensitive and selective electrode for determination of Hg(II). Mercury ion is first accumulated on the electrode surface via an open circuit procedure. After reduction of Hg(II) ions to its metallic form at a negative pre potential, square wave anodic stripping voltammetry was applied to generate the electrochemical signal. The high affinity of the Hg-IP-NPs for Hg(II) was substantiated by comparing of the signals of electrodes with imprinted and non imprinted polymer. The beneficial effect of MWCNTs on the voltammetric signal is also demonstrated. Under the optimized conditions and at a typical working potential of +0.05 V (vs. Ag/AgCl), the electrode has a linear response in the 0.1-20 nmol L-1 Hg(II) concentration range and a 29 pM detection limit. The electrochemical sensitivity is as high as 1441 A.M-1.cm-2 which is among the best values known. The electrode was applied to the determination of Hg(II) in water samples. Graphical abstract Schematic representation of the sensor electrode modified with mercury-imprinted polymer nanoparticles, and the recognition and voltammetric determination steps.

AB - Boron and nitrogen codoped carbon dots functionalized with cyclodextrin (beta-CD N/B-C-dots) were obtained from beta-cyclodextrin. The material displays strong fluorescence (with excitation/emission peak wavelengths of 400/500 nm) and was characterized by UV-vis, transmission electron microscopy and FTIR. If the substrate p-nitrophenylphosphate is enzymatically cleaved by alkaline phosphatase (ALP), a yellow product is formed whose absorption overlaps the excitation spectrum of the beta-CD-N/B-C-dots. Hence, fluorescence is reduced due to an inner filter effect. In additon, the beta-CD cavity offers a pocket for substrate recognition. The findings were used to design a method for the determination of the activity of ALP. It has a working range that extends from 0.003 to 5.5 U.L-1, with a 0.3 mU.L-1 detection limit. The method is fast, simple, inexpensive, and highly sensitive and selective. Graphical abstract Schematic of an inner filter effect based probe for alkaline phosphatase based on the use boron and nitrogen co-doped carbon dots (N/B-C-dots) modified with beta-cyclodextrin (beta-CD). PNPP: p-Nitrophenylphosphate; PNP: p-Nitrophenol anion. PMID- 29594533 TI - Determination of RNase H activity via real-time monitoring of target-triggered rolling circle amplification. AB - The authors describe a method for real-time monitoring of the activity of ribonuclease H (RNase H). It is based on target-triggered rolling circle amplification (RCA). It utilizes a specially designed primer that contains a RNA sequence in the center and an amino group at the 3'-end. In the absence of RNase H, the primer when hybridized to a circular DNA template is not extended by DNA polymerase due to the amino group at the 3'-end. In contrast, the presence of RNase H specifically degrades the RNA sequence of the primer hybridized to the circular DNA template. This results in the conversion of the 3'-amino group to a 3'-hydroxy group and thereby enables the extension reaction promoted by DNA polymerase. This, consequently, leads to efficient RCA producing a long concatenated DNA strand. Its generation can be monitored in real-time by using the fluorescent dye SYBR green II which is specific for single-stranded DNA. Based on this RNase H-triggered RCA, RNase H activity can be selectively determined at levels as low as 0.019 U.mL-1 with a total assay time of <5 min. The diagnostic capability of this assay was demonstrated by monitoring the activity of RNase H in tumor cells. Graphical abstract Schematic of real-time monitoring of ribonuclease H (RNase H) activity based on target-triggered rolling circle amplification (RCA). RNase H that degrades RNA in primer, converts 3' amino group to 3'-hydroxy group, which promotes RCA with fluorescence enhancement of the probe SYBR green II. PMID- 29594534 TI - Magnetic mesoporous polymelamine-formaldehyde resin as an adsorbent for endocrine disrupting chemicals. AB - A magnetic mesoporous poly(melamine-formaldehyde) composite (Fe3O4-mPMF) was prepared via grafting poly(melamine-formaldehyde) onto the surface of amino functionalized magnetite (Fe3O4) nanoparticles. The material was characterized by scanning electron micrography, transmission electron microscopy, X-ray diffraction, Fourier transform-infrared spectroscopy, nitrogen adsorption desorption isotherms, and thermogravimetric analysis. It has a large surface area, a typical mesoporous structure, and a high thermal stability. It was employed as a magnetic sorbent for the solid phase extraction of the following endocrine disrupting chemicals (EDCs): Bisphenol A, 4-tert-butylphenol, 4-tert octylphenol and nonylphenol. The EDCs were then quantified by HPLC. Under the optimized conditions, the response to the EDCs is linear in the range of 0.5-100 ng.mL-1, and the limits of detection are 0.02-0.1 ng.mL-1. The high adsorption capability of the Fe3O4-mPMF is mainly attributed to multiple interactions including pi-stacking, hydrogen bonding, and hydrophobic interactions. The method was applied to the extraction of EDCs from spiked river water and bottled juice samples. The results demonstrated that the Fe3O4-mPMF is an efficient adsorbent for the extraction of organic compounds with large conjugated pi-system, plenty of hydrogen-bonding sites, and strong hydrophobicity.

AB - A porous carbon material doped with an iron species (Fe/PC) was prepared by carbonizing a mixture of zeolitic imidazolate framework-8 in the presence of iron(II) ions. The resulting material was characterized by X-ray diffraction, nitrogen adsorption isotherms, transmission electron microscopy, and by Raman and X-ray photoelectron spectroscopy. Fe/PC was the deposited on the surface of glassy carbon electrode (GCE) to obtain a sensor for amperometric determination of phenolic compounds. The unique catalytic activity, good electrical conductivity and hierarchical structure of the Fe/PC composite results in good electrooxidative activity towards hydroquinone (HQ; typically at 44 mV) and catechol (CC; typically at 160 mV). Under optimal conditions, the amperometric responses are linear in the range from 0.1 to 120 MUmol . L-1 for HQ, and from 1.0 to 120 MUmol . L-1 for CC. The respective detection limits are 14 and 33 nmol . L-1. The sensor is highly selective against potential interferents and was successfully applied to the determination of HQ and CC contents in (spiked) water samples. Graphical abstract An amperometric sensor for phenolic compounds was constructed by using a metal-organic framework derived iron doped porous carbon material.

The purpose of this study was to evaluate whether black-bone (BB) magnetic resonance imaging (MRI), a non-ionising imaging method, offers an alternative to ionising imaging methods such as computed tomography (CT) in the examination of cranial deformities. METHODS: From 2012 to 2014, a total of 408 children were referred to the Craniofacial Centre at the Helsinki University Hospital for further examination due to flatness of the posterior skull. Fifteen of these patients required further diagnostic imaging. To avoid ionising radiation, we used an MRI protocol that included sequences for evaluation of both brain anatomy and skull bone and sutures by BB-MRI. A semi-automatic skull segmentation algorithm was developed to facilitate the visualisation. Two patients with scaphocephaly were included in the study to confirm the ability to differentiate synostosis with BB-MRI. RESULTS: We obtained informative 3D images using BB-MRI. Seven patients (7/15, 46.7%) had plagiocephaly on the right side and seven on the left side (7/15, 46.7%). One patient (1/15, 6.7%) had symmetric posterior flatness affecting both sides. Neither structural nor signal-intensity alterations of the brain were detected in visual analysis. CONCLUSION: BB-MRI provides an alternative to CT when imaging craniofacial deformities. BB-MRI provides not only high-quality 3D-reconstructed imaging of the bony structures and sutures but also information on brain structure in one imaging session. With further development, this method could replace ionising radiation-based methods in analysing deformities of the skull.

AB - A nanoporous carbon material was synthesized by heating potassium citrate without using a template or an activating agent. It is shown to represent a viable coating for use in solid-phase microextraction. The material is thermally stable and mainly consists of amorphous sheets of sp2-bonded carbon. It has an extensive pore structure and a surface area as large as 1236 m2.g-1. The nanoporous carbon was deposited on the surface of steel wires, and the resulting fibers were applied to the extraction of trace levels of chlorobenzenes in water samples. Following extraction by absorbing, the chlorobenzenes were quantified by gas chromatograph in combination with electron capture detection. Extraction temperature and time, and desorption temperature were optimized (80 degrees C, 10 min and 310 degrees C). Under optimized conditions, the calibration plots are linear in the following concentration ranges: 2.5 to 100 ng.L-1 (pentachlorobenzene), 5 to 200 ng.L-1 (1,2,3,4-tetrachlorobenzene), 10 to 100 ng.L-1 (hexachlorobenzene) and 10 to 500 ng.L-1 (1,2,3-trichlorobenzene, 1,2,4 trichlorobenzene, 1,3,5-trichlorobenzene). Other figures of merit include (a) high enrichment factors (8324 to 9920), (b) low limits of detection (0.10-1.03 ng.L-1), and (c) good reproducibility (relative standard deviations including intra-day and inter-day with a single fiber and fiber-to-fiber were below 6.4% at a mixed concentration level of 2.5, 5, and 10 ng.L-1 respectively in ultra water). This method was successfully applied to the determination of chlorobenzenes in (spiked) lake waters where it gave recoveries between 82.3% and 104.5%.

PMID- 29594538 TI - A review on chemiresistive room temperature gas sensors based on metal oxide nanostructures, graphene and 2D transition metal dichalcogenides. AB - Room-temperature (RT) gas sensing is desirable for battery-powered or self powered instrumentation that can monitor emissions associated with pollution and industrial processes. This review (with 171 references) discusses recent advances in three types of porous nanostructures that have shown remarkable potential for RT gas sensing. The first group comprises hierarchical oxide nanostructures (mainly oxides of Sn, Ni, Zn, W, In, La, Fe, Co). The second group comprises graphene and its derivatives (graphene, graphene oxides, reduced graphene oxides, and their composites with metal oxides and noble metals). The third group comprises 2D transition metal dichalcogenides (mainly sulfides of Mo, W, Sn, Ni, also in combination with metal oxides). They all have been found to enable RT sensing of gases such as NOx, NH3, H2, SO2, CO, and of vapors such as of acetone, formaldehyde or methanol. Attractive features also include high selectivity and sensitivity, long-term stability and affordable costs. Strengths and limitations of these materials are highlighted, and prospects with respect to the development of new materials to overcome existing limitations are discussed. Graphical Abstract The review summarizes the most significant progresses related to room temperature gas sensing by using hierarchical oxide nanostructures, graphene and its derivatives and 2D transition metal dichalcogenides, highlighting the peculiar gas sensing behavior with enhanced selectivity, sensitivity and long term stability. PMID- 29594540 TI - FePO4 embedded in nanofibers consisting of amorphous carbon and reduced graphene oxide as an enzyme mimetic for monitoring superoxide anions released by living cells. AB - FePO4 is biocompatible and can act as a kind of promising enzyme mimetic. Unfortunately, the electrical conductivity of FePO4 is poor. In order to enhance its conductivity, FePO4 was embedded into nanofibers consisting of amorphous carbon and reduced graphene oxide (rGO) by an electrospinning technique. As a sensing material for monitoring superoxide anion (O2*-) and typically operated at 0.5 V (vs. SCE), it displays high sensitivity (9.6 MUA?MUM-1?cm-2), a low detection limit (9.7 nM at S/N = 3), a wide linear response range (10 nM to 10 MUM), and fast response (1.6 s). Due to its low detection limit and fast response, the sensor in our perception has a large potential for detecting superoxide anions released by HeLa cancer cells. Graphical abstract Schematic of the microstructure of FePO4/C and FePO4/rGO-C nanofibers, a photograph of cancer cells (HeLa), and the electrochemical response towards O2-* of the sensor. PMID- 29594541 TI - Ratiometric detection of hydroxy radicals based on functionalized europium(III) coordination polymers. AB - A ratiometric fluorescent probe is described that is based on a functionalized europium(III) coordination polymer (Eu/DPA-TA). It can be fabricated by using dipicolinic acid (DPA) as a bridging ligand (to sensitize the Eu3+ fluorescence) and terephthalic acid (TA) acting as a functional ligand to recognize the hydroxy radical (*OH). The quenching of Eu3+ fluorescence (measured at excitation/emission wavelengths of 288/615 nm) by water is strongly reduced in the presence of TA. This leads to a significant enhancement in the emission lifetime and intensity of Eu3+. Upon the addition of *OH, the fluorescence of Eu/DPA-TA showed ratiometric changes in that the TA sensitized fluorescence (peaking at 445 nm) is switched on, while the plain Eu3+ fluorescence (peaking at 615 nm) decreases. This finding led to a method for the ratiometric (2 wavelength) detection of OH with a 0.5 MUM detection limit. The method also allows OH to be detected with bare eyes at OH concentrations as low as 10 MUM. In our perception, this study paves the way towards the design of new functionalized lanthanide coordination polymers for fluorometric assays and biomedical imaging. Graphical abstract Schematic of a ratiometric fluorescent assay for the detection of hydroxy radical (*OH) based on the use of a europium(III)/dipicolinic acid coordination polymer (Eu/DPA CP) functionalized with terephthalic acid (TA). A gradual color change from red to blue can be observed and correlated to *OH concentrations. PMID- 29594542 TI - A hyper-cross linked polymer as an adsorbent for the extraction of chlorophenols. AB - A porous material (polytriphenylamine; PTPA) was synthesized by using triphenylamine as the monomer and dimethoxymethane as the cross-linker. PTPA was characterized by Fourier infrared spectrometry, X-ray diffraction measurements, scanning electron microscopy and N2 adsorption-desorption isotherms. The PTPA has a spherical-shape morphology and relatively high specific surface area. It is shown to be a viable adsorbent for solid phase extraction of 3-chlorophenol, 2,3 dichlorophenol, 2,4-dichlorophenol and 2,4.6-trichlorophenol prior to their determination by high performance liquid chromatography-mass spectrometry. Under the optimized conditions, recoveries from spiked samples are in the range from 92.5% to 106.3%. The limits of detection range from 0.03 to 0.3 ng mL-1 (at an S/N ratio of 3) in case of bottled juice, and from 0.03 to 0.1 ng g-1 in case of tomato samples. The enrichment factors for the four analytes are in the range of 127-183 for bottle juice, and from 110-150 for tomatos. Response is linear in the range of 1.0 to 40.0 ng mL-1 for juice, and 0.3-40.0 ng g-1 for tomatos. The relative standard deviations for the determination of the chlorophenols at 20 ng mL-1 in bottled beverage, and 20 ng g-1 in tomatos are lower than 5.7%. Graphical abstract A polytriphenylamine polymer (PTPA) was prepared by using an external cross-linker method with triphenylamine as monomer and dimethoxymethane as cross linker, and it was used as an adsorbent to extract chlorophenols from juice and vegetable samples. PMID- 29594543 TI - Switched voltammetric determination of ractopamine by using a temperature responsive sensing film. AB - This study describes an electrochemical sensor for the animal growth promoter ractopamine. The method is based on the use of a glassy carbon electrode (GCE) modified with a temperature-responsive sensing film composed of reduced graphene oxide, C60 fullerene, and the temperature-sensitive polymer poly(2-(2 methoxyethoxy)ethyl methacrylate) (PMEO2MA). The modified GCE was characterized by scanning electron microscopy and electrochemical impedance spectroscopy. A large oxidation peak current can be observed (maximum typically at 0.57 V vs. Ag/AgCl) when the temperature is raised to above the lower critical solution temperature of PMEO2MA. This peak disappears at lower temperature. Under optimum conditions, the sensor has a detection range for ractopamine from 0.1 to 3.1 MUM, with an 82 nM detection limit. The method was successfully applied to the determination of ractopamine in spiked pork samples. Graphical abstract Schematic presentation of the reversible, temperature-controlled "on/off" electrochemical behavior of ractopamine at a glassy carbon electrode modified with a film composed of reduced graphene oxide (rGO), C60 fullerene and the poly(2-(2 methoxyethoxy)ethyl methacrylate) (PMEO2MA). PMID- 29594544 TI - Voltammetric determination of the Escherichia coli DNA using a screen-printed carbon electrode modified with polyaniline and gold nanoparticles. AB - The authors describe an electrochemical assay for fast detection of Escherichia coli (E. coli). It is based on a dual signal amplification strategy and the use of a screen-printed carbon electrode (SPCE) whose surface was modified with a polyaniline (PANI) film and gold nanoparticles (AuNPs) via cyclic voltammetry (CV). In the next step, avidin was covalently immobilized on the PANI/AuNP composite on the SPCE surface. Subsequently, the biotinylated DNA capture probe was immobilized onto the PANI/AuNP/avidin-modified SPCE by biotin-avidin interaction. Then, DNA of E.coli, digoxigenin-labeled DNA detector probe and anti digoxigenin-labeled horseradish peroxidase (HRP) were placed on the electrode. 3,3',5,5'-Tetramethylbenzidine (TMB) and H2O2 solution were added and the CV electrochemical signal was generated at a potential of -0.1 V (vs. Ag/AgCl) and a scan rate 50 mV.s-1. The assay can detect 4 * 106 to 4 CFU of E. coli without DNA amplification. The biosensor is highly specific over other pathogens including Klebsiella pneumoniae, Proteus mirabilis, Enterococcus faecalis, Staphylococcus haemolyticus and Pseudomonas aeruginosa. It can be concluded that this genosensor has an excellent potential for rapid and accurate diagnosis of E.coli inflicted infections.

PMID- 29594545 TI - Lower back and neck pain among dentistry students: a cross-sectional study in dentistry students in Northern Greece. AB - INTRODUCTION: Dentistry students and dentists comprise a unique group of professionals, whose everyday professional activity requires long hours of standing and working in a position considered unhealthy for the lower back and neck. Our aim was to explore the factors involved in the appearance of low back and neck pain in dentistry students as well as the impact of the pain on the students' professional and everyday activities. MATERIALS AND METHODS: A questionnaire was given to all dentistry students of the 4th and 5th year of our university. The questionnaire included 43 questions regarding demographic data, history (spinal injury, other comorbidities), daily activities (exercise, smoking, alcohol and caffeine consumption, use of cell phone), professional activities (length and type of dental work), pattern and intensity of pain, and personal pain evaluation. A statistical analysis of the gathered data was performed. RESULTS: All students having suffered a spinal trauma or indicating any other comorbidity that could cause severe pain of the spine were excluded from the study. Fifty-five students (21 male, 34 female) were included. Our data showed that increased alcohol consumption and prolonged use of cell phone were connected to increased levels of pain. The students reported that the most frequent onset of pain was 1 h after starting to work in a standing position, while the majority believed that their working habits were involved in the appearance and the intensity of neck and low-back pain. CONCLUSION: Our findings indicate that among dentistry students appears to be a causative relationship between their professional activities and the experienced spinal pain. These findings may be useful in a possible future restructuring of the educational program in dental schools, as well as in improving the ergonomics of dentistry working units.

AB - Nanosized single crystal orthorhombic Bi2WO6 was synthesized by a hydrothermal method and used as a sorbent for vortex assisted solid phase extraction of lead(II). The crystal and molecular structure of the sorbent was examined using XRD, Raman, SEM and SEM-EDX analysis. Various parameters affecting extraction efficiency were optimized by using multivariate design. The effect of diverse ions on the extraction also was studied. Lead was quantified by flame atomic absorption spectrometry (FAAS). The recoveries of lead(II) from spiked samples (at a typical spiking level of 200-400 ng.mL-1) are >95%. Other figures of merit includes (a) a detection limit of 6 ng.mL-1, (b) a preconcentration factor of 50, (c) a relative standard deviation of 1.6%, and (d) and adsorption capacity of 6.6 mg.g-1. The procedure was successfully applied to accurate determination of lead in (spiked) pomegranate and water samples.

PMID- 29594547 TI - A molecularly imprinted polymer placed on the surface of graphene oxide and doped with Mn(II)-doped ZnS quantum dots for selective fluorometric determination of acrylamide. AB - A polymer imprinted with acrylamide (AM-MIP) was synthesized on the surface of graphene oxide by surface polymerization of propionamide (serving as a dummy template), methacrylic acid (as the functional monomer) and ethylene glycol dimethacrylate (the cross-linker). ZnS quantum dots (QDs) doped with Mn(II) ions were added to the AM-MIP to act as fluorescence source. The AM-MIP was characterized by infrared spectroscopy, scanning electron microscopy and X-ray powder diffraction, suggesting that the imprinted layer was successfully grafted onto graphene oxide. The fluorescence of the doped QDs is quenched when loading the AM-MIP with acrylamide (AM), and the quenching effect is much stronger than the non-imprinted polymer (AM-NIP). Quenching follows Stern-Volmer kinetics. The combination of imprinting and fluorometric detection offer AM-IIP capability to accumulate trace AM before direct determination, omitting desorption and separation or other methods. The excitation and emission spectra of AM-MIP peak at 325 nm and 601 nm, respectively. Under optimal conditions, fluorescence drops linearly in the 0.5-60 MUmol.L-1 acrylamide concentration range, and the detection limit is 0.17 MUmol.L-1. The method has been applied to the determination of AM in spiked water samples and gave recoveries in the range from 100.2 to 104.5%, with relative standard deviations in the 1.9 to 3.9% range. In our perception, the AM-MIP presented here is a promising fluorescent probe for the detection of trace acrylamide in food. Graphical abstract Schematic of the preparation of graphene oxide coated with a molecularly imprinted polymer doped with Mn(II)-doped ZnS quantum dots. Propionamide serves as a dummy template. Acrylamide acts as a quencher of fluorescence, and this effect is used for its selective fluorometric determination. PMID- 29594548 TI - Psychiatric co-morbidity, distress, and use of psycho-social services in adult glioma patients-a prospective study. AB - BACKGROUND: Distress impacts the daily life of glioma patients. This study explored its course over time and the usage of psychosocial care. METHODS: A consecutive sample of glioma patients completed the Hospital Anxiety and Depression Scale to assess distress levels at admission to the hospital (t1), before discharge (t2), after 3 months (t3), and after 6 months (t4). They were interviewed with the Structured Clinical Interview for DSM-IV to ascertain psychiatric disorders at t2. Psycho-oncological care in the hospital was determined with the Hospital Information System, and the use of outpatient treatment was evaluated with the Health Care Usage Questionnaire at t4. We compared the percentages of elevated distress, psychiatric co-morbidity, and care usage between men and women. RESULTS: During the study period, 37 patients were enrolled. Nineteen percent of the patients were diagnosed with a psychiatric disorder. The percentages of patients with elevated distress were 56, 59, 39, and 40% at t1, t2, t3, and t4, respectively. Participants who did not survive the 6 months presented with higher levels of distress. In the hospital, 14% of those with elevated distress were visited by a psycho-oncologist. In the outpatient setting, 43% of those with elevated distress visited a neuro-psychiatrist, and 14% went to a psychotherapist. There was no evidence for an effect of gender on psychiatric co-morbidity, distress, or care use. CONCLUSIONS: A significant proportion of glioma patients report elevated distress during the hospital stay and thereafter. Only a fraction of them receive mental health care.

AB - Porphyrin-based porous organic polymers (P-POPs) are amorphous polymers linked by strong covalent bonds between the porphyrin subunits that act as building blocks. The authors describe a magnetic P-POP that possesses high surface area, a highly porous structure, and strong magnetism. The MP-POP was employed as a magnetic sorbent for the extraction of benzoylurea insecticides from cucumber and tomato samples prior to their determination by HPLC. The sorbent has a typical sorption capacity of 1.90-2.00 mg?g-1. The method exhibits a good linear range (0.8-160 ng.g-1), low limits of detection (0.08-0.2 ng.g-1), and high method recoveries (81.8-103.5%) for cucumber and tomato samples. The MP-POP has different adsorption capabilities for the benzoylurea insecticides, phenylurea herbicides and phenols compounds, and the adsorption mechanism is found to be based on pi stacking, hydrogen-bonding, and hydrophobic interactions. Graphical abstract A novel magnetic porphyrin-based porous organic polymer was fabricated and used as the adsorbent for the efficient extraction of benzoylurea insecticides. PMID- 29594550 TI - Voltammetric sensing of dopamine based on a nanoneedle array consisting of NiCo2S4 hollow core-shells on a nickel foam. AB - An array consisting of homogeneous NiCo2S4 hollow core-shell nanoneedles was fabricated and is shown to enable sensitive electrochemical determination of dopamine (DA). The array was grown directly on a nickel foam (NF) substrate by a two-step hydrothermal process. The hierarchical nanoarray consists of a homogeneous NiCo2S4 nanoneedle core and a NiCo2S4 nanosheet shell. A 3 dimensional micro/nano structure is formed due to the presence of the micropores of the NF. The electrode was characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Compared to a plain NF electrode, the NiCo2S4-modified NF electrode displays higher electrocatalytic activity for the oxidation of DA by differential pulse voltammetry (DPV). The sensor, best operated at a typical working voltage of 134 mV (vs. saturated calomel electrode), has a linear response in the 0.5-100 MUM DA concentration range and a 0.2 MUM detection limit (at S/N = 3). The electrode is selective over ascorbic acid and uric acid.

PMID- 29594551 TI - Pair-matched patient-reported quality of life and early oncological control following focal irreversible electroporation versus robot-assisted radical prostatectomy. AB - PURPOSE: The design, conduct and completion of randomized trials for curative prostate cancer (PCa) treatments are challenging. To evaluate the effect of robot assisted radical prostatectomy (RARP) versus focal irreversible electroporation (IRE) on patient-reported quality of life (QoL) and early oncological control using propensity-scored matching. METHODS: Patients with T1c-cT2b significant PCa (high-volume ISUP 1 or any 2/3) who received unifocal IRE were pair-matched to patients who received nerve-sparing RARP. Patient-reported outcomes were prospectively assessed using the Expanded Prostate Cancer Index Composite (EPIC), AUA symptom score and Short Form of Health Survey (SF-12) physical and mental components. Oncological failure was defined as biochemical recurrence (RARP) or positive follow-up biopsies (IRE). Generalized mixed-effect models were used to compare IRE and RARP. RESULTS: 50 IRE patients were matched to 50 RARP patients by propensity score. IRE was significantly superior to RARP in preserving pad free continence (UC) and erections sufficient for intercourse (ESI). The absolute differences were 44, 21, 13, 14% for UC and 32, 46, 27, 22% for ESI at 1.5, 3, 6, and 12 months, respectively. The EPIC summary scores showed no statistically significant differences. Urinary symptoms were reduced for IRE and RARP patients at 12 months, although IRE patient initially had more complaints. IRE patients experienced more early oncological failure than RARP patients. CONCLUSIONS: These data demonstrated the superior preservation of UC and ESI with IRE compared to RARP up to 12 months after treatment. Long-term oncological data are warranted to provide ultimate proof for or against focal therapy. PMID- 29594552 TI - Determination of protein kinase A activity and inhibition by using hydroxyapatite nanoparticles as a fluorescent probe. AB - The authors describe a fluorometric method for the determination of the activity and inhibition of protein kinase A (PKA). In the presence of ATP, PKA catalyzes the transfer of phosphate groups from ATP to a peptide, and the generated phosphorylated peptide quenches the fluorescence (measured at excitation/emission peaks of 340/440 nm) of the hydroxyapatite nanoparticles (HAP-NPs). A linear logarithmic relationship of PKA concentrations with fluorescence intensity in the range from 1 to 50 U.L-1 was obtained, and the lower limit of detection (LOD) is 0.5 U.L-1. This is much lower than LODs reported in the literature. The PKA inhibitor H-89 was studied, and the inhibition plot has a sigmoidal shape with a half-maximal inhibitory concentration of around 750 nM of H-89. At a 4.5 nM level of H-89, fluorescence of HAP-NPs fell to levels of no PKA controls, demonstrating that the assay is a viable tool to screen for kinase inhibitors. An assay with Hela cell lysates in combination with forskolin (an activator of adenylyl cyclase) and IBMX (a phosphodiesterase inhibitor used to activate the cellular activity of PKA) resulted in decreased fluorescence of HAP-NPs. This suggests that the assay can be applied for testing in vitro cell kinase activity. In our perception, this method will enable high-throughput screening for kinase-related drugs and fluorometric enzymatic detection in various areas. Graphical abstract Fluorescence assay based on hydroxyapatite nanoparticles (HAP) fluorescence quenching was developed for analysis of the activity and inhibition of protein kinase A (PKA). PMID- 29594553 TI - A new kind of highly sensitive competitive lateral flow immunoassay displaying direct analyte-signal dependence. Application to the determination of the mycotoxin deoxynivalenol. AB - A new kind of competitive immunochromatographic assay is presented. It is based on the use of a test strip loaded with (a) labeled specific antibodies, (b) a hapten-protein conjugate at the control zone, and (c) antibodies interacting with the specific antibodies in the analytical zone. In the case where a sample does not contain the target antigen (hapten), all labeled antibodies remain in the control zone because of the selected ratio of reactants. The analytical zone remains colorless because the labeled antibodies do not reach it. If an antigen is present in the sample, it interferes with the binding of the specific antibodies in the control zone and knocks them out. Some of these antibodies pass the control zone to form a colored line in the analytical zone. The intensity of the color is directly proportional to the amount of the target antigen in the sample. The assay has an attractive feature in that an appearance in coloration is more easily detected visually than a decoloration. Moreover, the onset of coloration is detectable at a lower concentration than a decoloration. The new detection scheme was applied to the determination of the mycotoxin deoxynivalenol. The visual limit of detection is 2 ng.mL-1 in corn extracts (35 ng per gram of sample). With the same reagents, this is lower by a factor of 60 than the established test strip. The assay takes only 15 min. This new kind of assay has wide potential applications for numerous low molecular weight analytes. Graphical abstract Competitive immunochromatography with direct analyte-signal dependence is proposed. It provides a 60-fold decrease of the detection limit for mycotoxin deoxynivalenol. The analyte-antibody-label complexes move along the immobilized antigen (control zone) and bind with anti-species antibodies (test zone). PMID- 29594554 TI - Microextraction of polycyclic aromatic hydrocarbons by using a stainless steel fiber coated with nanoparticles made from a porous aromatic framework. AB - A porous aromatic framework of type PAF-6 was synthesized and explored as a coating onto a steel wire for using in solid-phase microextraction of polycyclic aromatic hydrocarbons (PAHs), phthalate plasticizers, and n-alkanes. The extraction temperature, extraction time, salt concentration, agitation speed, desorption temperature, and desorption time were optimized. This method for SPME resulted in the enrichment factors ranging from 122 to 1090 for PAHs (naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene), from 122 to 271 for plasticizers (diisobutyl phthalate, dibutyl phthalate, benzyl butyl phthalate, dicyclohexyl phthalate), and from 9 to 113 for n-alkanes (n-undecane, n-dodecane, n-tridecane, n-tetradecane, n-pentadecane, n hexadecane, n-octadecane and n-eicosane). The good extraction of the PAHs is assumed to be due to their pi-stacking interaction and hydrophobic effect. The PAF-6 coated fibers are durable and can be reused more than 100 times without significant loss of extraction performance. In combination with GC-MS detection, the method has limits of detection in the range from 0.8 to 4.2 ng L-1 in case of PAHs. The relative standard deviations for five replicate determinations of the PAHs by using one fiber are in the range from 5.2 to 8.5%. When using different fibers, they range from 7.1 to 9.6%. The recoveries of PAHs from water samples at a spiking level of 20 ng L-1 are in the range from 89.5 to 103.1%, with relative standard deviations ranging from 4.0 to 9.3%. Graphical abstract A porous aromatic framework of type PAF-6 was synthesized and used as a novel coating for the solid-phase microextraction of polycyclic aromatic hydrocarbons prior to their determination by gas chromatography with mass spectrometric detection. PMID- 29594555 TI - Enantiomeric separation of adrenaline, noradrenaline, and isoprenaline by capillary electrophoresis using streptomycin-modified gold nanoparticles. AB - Enantiomeric separations of the adrenergic compounds adrenaline, noradrenaline, and isoprenaline were studied. Electromigrative separations were performed in uncoated fused silica capillaries using streptomycin-modified gold nanoparticles (ST-AuNPs) as an additive to the background electrolyte. The ST-AuNPs are shown to serve as an effective chiral selector. The modified AuNPs were characterized in terms of size and zeta potential, and by IR and UV-vis spectra. The effects of ST-AuNP concentration, pH value, temperature, and separation voltage on the separations were systematically studied. Under optimized experimental conditions, racemic mixtures of the respective adrenergic drugs were baseline-separated within 7 min with a resolution of up to 7.5. The relative standard deviations of the resolution in inter-day and intra-day studies (n = 5) were generally <5%. Graphical abstract Schematic of the method for enantiomeric separations. (A): At low concentrations of streptavidinylated gold nanoparticles (ST-AuNPs), the better matching enantiomer is preferably "transported" by the ST-AuNPs; (B) ST AuNP concentration increased to an optimal value; (C): The ST-AuNP concentration is too high; even poorly matching enantiomers will be transported simultaneously.

AB - A stir foam composed of graphene oxide, poly(ethylene glycol) and natural latex (GO-PEG-NL) was prepared for use in micro-solid phase extraction sorbent of preservative agents and antioxidants from cosmetic products. The extracted analytes were quantified by GC-MS. Under the optimized conditions, the calibration plots are linear in the concentration ranges between 5.0 MUg.L-1 to 1.0 mg.L-1 for benzoic acid, of 10.0 MUg.L-1 to 1.0 mg.L-1 for 2-methyl-3 isothiazolinone (MI), and between 1.0 MUg.L-1 and 1.0 mg.L-1 for both 3-tert butyl-4-hydroxyanisole (BHA) and 2,6-di-tert-butyl-p-hydroxytoluene (BHT). The LODs are 1.0 MUg.L-1 for benzoic acid, 5.0 MUg.L-1 for MI and 0.5 MUg.L-1 for both BHA and BHT. The stir-foam can be easily prepared, is inexpensive and well reproducible (RSDs <3%, for n = 6). It can be re-used for up to 12 times after which extraction efficiency has dropped to 90%. The method was successfully applied to the determination of preservatives and antioxidants in cosmetic samples. Recoveries from spiked samples ranged between 94.5 +/- 2.1% and 99.8 +/- 1.8%. Graphical abstract A stir foam was prepared from graphene oxide, poly(ethylene glycol) and natural latex (GO-PEG-NL) and is shown to be a most viable sorbent for the microextraction of trace amounts of preservative agents and antioxidants from cosmetic products. PMID- 29594557 TI - Aptamer based voltammetric determination of ampicillin using a single-stranded DNA binding protein and DNA functionalized gold nanoparticles. AB - An aptamer based method is described for the electrochemical determination of ampicillin. It is based on the use of DNA aptamer, DNA functionalized gold nanoparticles (DNA-AuNPs), and single-stranded DNA binding protein (ssDNA-BP). When the aptamer hybridizes with the target DNA on the AuNPs, the ssDNA-BP is captured on the electrode surface via its specific interaction with ss-DNA. This results in a decreased electrochemical signal of the redox probe Fe(CN)63- which is measured best at a voltage of 0.188 mV (vs. reference electrode). In the presence of ampicillin, the formation of aptamer-ampicillin conjugate blocks the further immobilization of DNA-AuNPs and ssDNA-BP, and this leads to an increased response. The method has a linear reposne that convers the 1 pM to 5 nM ampicillin concentration range, with a 0.38 pM detection limit (at an S/N ratio of 3). The assay is selective, stable and reproducible. It was applied to the determination of ampicillin in spiked milk samples where it gave recoveries ranging from 95.5 to 105.5%. Graphical abstract Schematic of a simple and sensitive electrochemical apta-biosensor for ampicillin detection. It is based on the use of gold nanoparticles (AuNPs), DNA aptamer, DNA functionalized AuNPs (DNA AuNPs), and single-strand DNA binding protein (SSBP).

AB - Species that are currently listed under the genus Brevibacillus (formerly, Bacillus brevis cluster) have been a rich source of antimicrobial peptides for many decades. The first known peptide antibiotic, gramicidin, is presumed to be produced by a Brevibacillus sp. Members of the genus are widely spread in nature. They can be found in a variety of environments including intestinal tracts of animals, seawater, and soil. Some Brevibacillus strains have been used commercially as probiotics. Bioactive peptides produced by Brevibacillus spp. include antibacterial, antifungal and anti-invertebrate agents. Brevibacillus antimicrobial peptides are synthesized through ribosomal or nonribosomal pathway; these two groups can be further categorized based on specific structural features such as cyclization and presence of lipid chain. Some of the antimicrobial compounds produced by this genus share structural similarities that were overlooked previously. For example, the structural similarity between BT peptide, brevibacillin, and bogorol was revealed only recently. Here we review and classify Brevibacillus antimicrobial peptides and summarize their bioactivities and potential applications. PMID- 29594559 TI - A lateral flow immunoassay for straightforward determination of fumonisin mycotoxins based on the quenching of the fluorescence of CdSe/ZnS quantum dots by gold and silver nanoparticles. AB - A lateral flow immunoassay (LFIA) was developed for the determination of fumonisin mycotoxins. The fluorescence of CdSe/ZnS quantum dots (QDs), observed at excitation/emission wavelengths of 365/525 nm, is suppressed by the addition of silver nanoparticles (SNPs) or gold nanoparticles (GNPs) because SNPs overlap the excitation bands of the QDs, and GNPs overlap the emission bands. The fluorescence of the QDs is recovered upon addition of fumonisins, allowing for the sensitive detection in "positive mode" of the target mycotoxin by monitoring the changes of the QDs fluorescence intensity. The SNPs are found to be the most effective quenchers, while the use of GNPs allows for an efficient recovery of fluorescence and can be employed in the LFIA. The method was successfully applied to the fluorometric determination of fumonisins in spiked maize flour samples. The visual detection limit is at the ng.mL-1 level. This is four times lower compared to the colorimetric LFIA based on the use of the conventional gold NPs. Graphical abstract Schematic of the fluorescence quenching lateral flow immunoassay that uses fluorescent quantum dots (QD) and metal nanoparticles (NP) as the quencher: the binding of NP-labelled antibody to the antigen (purple triangle) modulates QD luminescence at the Test line, allowing for 'positive mode' detection of fumonisins. The NP accumulation at Control line assures validity of the test. PMID- 29594561 TI - Microfluidic paper-based device for colorimetric determination of glucose based on a metal-organic framework acting as peroxidase mimetic. AB - This work presents a microfluidic paper-based analytical device (MUPAD) for glucose determination using a supported metal-organic framework (MOF) acting as a peroxidase mimic. The catalytic action of glucose oxidase (GOx) on glucose causes the formation of H2O2, and the MOF causes the oxidation of 3,3',5,5' tetramethylbenzidine (TMB) by H2O2 to form a blue-green product with an absorption peak at 650 nm in the detection zone. A digital camera and the iOS feature of a smartphone are used for the quantitation of glucose with the S coordinate of the HSV color space as the analytical parameter. Different factors such as the concentration of TMB, GOx and MOF, pH and buffer, sample volume, reaction time and reagent position in the MUPAD were optimized. Under optimal conditions, the value for the S coordinate increases linearly up to 150 MUmol.L-1 glucose concentrations, with a 2.5 MUmol.L-1 detection limit. The MUPAD remains stable for 21 days under conventional storage conditions. Such an enzyme mimetic based assay to glucose determination using Fe-MIL-101 MOF implemented in a microfluidic paper-based device possesses advantages over enzyme-based assays in terms of costs, durability and stability compared to other existing glucose determination methods. The procedure was applied to the determination of glucose in (spiked) serum and urine.

AB - Ergosterol is the predominant nature sterol constituent of plasma membrane in Saccharomyces cerevisiae. Herein, the biosynthetic pathway of ergosterol was proposed to be metabolically engineered for the efficient production of ergosta 5,7-dien-3beta-ol, which is the precursor of vitamin D4. By target disruption of erg5, involved in the end-steps of post-squalene formation, predominantly accumulated ergosta-5,7-dien-3beta-ol (4.12 mg/g dry cell weight). Moreover, the rate-limiting enzymes of ergosta-5,7-dien-3beta-ol biosynthesis were characterized. Overexpression of Hmg1p led to a significant accumulation of squalene, and induction of Erg1p/Erg11p expression raised the yield of both total sterols and ergosta-5,7-dien-3beta-ol with no obvious changes in growth behavior. Furthermore, the transcription factor allele upc2-1 was overexpressed to explore the effect of combined induction of rate-limiting enzymes. Compared with an obviously enhanced yield of ergosterol in the wild-type strain, decreases of both the ergosta-5,7-dienol levels and the total sterol yield were found in Deltaerg5 upc2-1, probably due to the unbalanced NADH/NAD+ ratio observed in the erg5 knockouts, suggesting the whole-cell redox homeostasis was also vital for end product biosynthesis. The data obtained in this study can be used as reference values for the production of sterol-related intermediates involved in the post squalene biosynthetic pathway in food-grade S. cerevisiae strains.

AB - The work describes a hybrid electrochemical sensor for highly sensitive detection of the anesthetic lidocaine (LID). Porous carbon (PC) was synthesized from an isoreticular metal-organic framework-8 (IRMOF-8) and drop cast onto a glassy carbon electrode (GCE). A layer of a molecularly imprinted polymer (MIP) layer was then fabricated in situ on the modified GCE by electro-polymerization, with LID acting as the template and resorcinol as the functional monomer. Hexacyanoferrate is used as an electrochemical probe. The electrical signal (typically acquired at 0.335 V vs. SCE) increases linearly in the 0.2 pM to 8 nM LID concentration range, with a remarkable 67 fM detection limit (at an S/N ratio of 3). The sensor is stable and selective. Eventually, rapid and accurate detection of LID in spiked real samples was successfully realized. Graphical abstract ?. PMID- 29594563 TI - Immobilization of horseradish peroxidase on amino-functionalized carbon dots for the sensitive detection of hydrogen peroxide. AB - The authors describe the preparation of amino-functionalized carbon dots (NH2 CDs) via a one-step hydrothermal process using silver nitrate and chitosan as the precursors. The NH2-CDs have a fairly consistent size distribution with an average size of 2.8 +/- 0.5 nm. This is attributed to the introduction of Ag(I) both as a catalyst and a precipitant. The NH2-CDs are highly crystalline. Their surface carries amino groups and carboxy groups which is confirmed by transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. Horseradish peroxidase (HRP) was immobilized in the NH2-CDs and then placed on a glassy carbon electrode (GCE). Spectroscopic and electrochemical analyses evidenced the stability and good bioactivity of the immobilized HRP. This reveals that NH2-CD is a desirable matrix for enzyme immobilization. The modified GCE exhibits enhanced electro-catalytic activity towards hydrogen peroxide (H2O2) reduction as compared to that of plain CDs. The effects of pH value and loading on the performances of the modified GCEs were studied. Under optimized conditions, the biosensor has a linear response in the 5 to 590 nM H2O2 concentration range, with a 1.8 nM defection limit (at an S/N ratio of 3). The sensor is stable, reproducible and selective. Finally, the sensor was applied to determine H2O2 in real samples, and satisfactory recoveries were achieved. Graphical abstract Amino-functionalized carbon dots (NH2-CDs) can provide more active sites and a friendly microenvironment for horseradish peroxidase (HRP) immobilization. Thus, a novel sensitive H2O2 biosensor has been developed.

AB - A film of perovskite-type LaFeO3 nanoparticles (NPs) was deposited on fluorine doped tin oxide (FTO) conducting glass via dipping-lifting and calcination. Scanning electron microscopy shows that the NPs are evenly distributed on the surface of the glass. The modified glass was further coated with antibody against human interleukin 6 (IL-6) to result in a photoelectrochemical immunosensor for IL-6. The well-established photoelectrochemical immunoassay has a linear current response in the range of 0.1 pg.mL-1 to 0.1 MUg.mL-1 and a detection limit as low as 33 fg.mL-1. Graphical abstract Schematic of a novel photoelectochemical immunoassay for the measurement of IL-6 based on perovskite-type LaFeO3 nanoparticles.

PMID- 29594565 TI - Electrochemical quercetin sensor based on a nanocomposite consisting of magnetized reduced graphene oxide, silver nanoparticles and a molecularly imprinted polymer on a screen-printed electrode. AB - An electrochemical quercetin (QR) sensor is described that is based on the use of magnetic reduced graphene oxide (MrGO) incorporated into a molecularly imprinted polymer (MIP) on the surface of a screen-printed electrode (SPE). The MrGO consists of reduced graphene oxide (rGO), magnetite (Fe3O4) and silver nanoparticles (Ag). The analyte (QR) is electrostatically adsorbed on the surface of the MrGO. Finally, the MIP was deposited via in-situ polymerization. The composite was characterized by X-ray diffraction, Fourier transform infrared spectroscopy and Vibrating sample magnetometry. The morphologies and electrochemical properties of different electrodes were characterized by Field emission scanning electron microscopy, Electrochemical impedance spectroscopy and differential pulse voltammetry. Under optimal conditions, the modified electrode has a linear response in the 20 nM to 250 MUM QR concentration range. The limit of detection is 13 nM (at an S/N ratio of 3). The electrode is selective, stable, regenerable and reliable. It was applied to the determination of QR in spiked pharmaceutical samples and gave satisfactory results. Graphical abstract Schematic presentation of a method for sensing quercetin. It is based on the use of screen printed electrode modified with magnetized reduced graphene oxide and a molecularly imprinted polymer. PMID- 29594567 TI - On-site preconcentration of pesticide residues in a drop of seawater by using electrokinetic trapping, and their determination by surface-enhanced Raman scattering. AB - The authors have developed a method for simultaneous quantification of several charged pesticides (as shown for amitrole, simazine, trichlorfon and bisultap). It is based on the use of a reduced graphene oxide-modified screen-printed electrode (RGO-SPE) and combines electrokinetic trapping (EKT) and surface enhanced Raman scattering (SERS). When a 50 MUL droplet containing negatively charged RGO and positively charged gold nanorods is placed on the SPE, the RGO and gold nanorods are selectively attracted on the surface of the SPE during EKT. This leads to the formation of sandwich-type hybrid substrates. The resulting substrates also contain Raman "hot spots" among the high-density gold nanorods. This, along with the excellent adsorption performance of RGO, makes it an excellent SERS substrate for on-site detection of the charged pesticides. The method is highly reproducible and long-term stable. The spot-to-spot variation of the intensity of the SERS is <15%, and the performance of SERS activity is maintained over a period of 6 weeks. The method works over a wide range of concentrations (0.5 nM to 4 MUM) for charged pesticides under optimal conditions, with a sub-nanomolar detection limit (at a signal to noise ratio of 3). The EKT SERS method requires only microliter volumes and takes only minutes for completion. Therefore, the method provides high sensitivity for detection while preserving the selectivity and stability required for reliable quantitative analysis. Graphical abstract A method combining electrokinetic trapping and SERS can be used for simultaneous detection of charged pesticides in a drop of seawater.

AB - An overview (with 376 refs.) is given here on the current state of methods for electrochemical sensing of glucose based on the use of advanced nanomaterials. An introduction into the field covers aspects of enzyme based sensing versus nonenzymatic sensing using nanomaterials. The next chapter cover the most commonly used nanomaterials for use in such sensors, with sections on uses of noble metals, transition metals, metal oxides, metal hydroxides, and metal sulfides, on bimetallic nanoparticles and alloys, and on other composites. A further section treats electrodes based on the use of carbon nanomaterials (with subsections on carbon nanotubes, on graphene, graphene oxide and carbon dots, and on other carbonaceous nanomaterials. The mechanisms for electro-catalysis are also discussed, and several Tables are given where the performance of sensors is being compared. Finally, the review addresses merits and limitations (such as the frequent need for working in strongly etching alkaline solutions and the need for diluting samples because sensors often have analytical ranges that are far below the glucose levels found in blood). We also address market/technology gaps in comparison to commercially available enzymatic sensors.

AB - D-Glucose was used as a dummy template in a strategy to fabricate boronate-based hollow molecularly imprinted polymers (h-MIPs) for the recognition of glycosides. 3-Aminophenylboronic acid (APBA) was selected as the functional monomer to impart glycoside binding capability. A polystyrene core was synthesized via an emulsifier-free emulsion polymerization. It was then be corroded to form a hollow structure where the binding sites on the inner surface can be fully utilized. Adsorption studies indicate that the resulting h-MIPs can specifically recognize glycosides. The h-MIPs were applied as a sorbent for solid phase extraction of the glycosides (daidzin, glycitin, rutin, and genistin) in soy products. Following desorption with 1% TFA in acetonitrile-water (3:7, v/v), the glycosides were quantified by HPLC with UV detection. The detection limits for the glycosides range from 3.5 to 10.8 ng.mL-1. Graphical abstract Boronate-affinity hollow molecularly imprinted polymers using D-glucose as dummy template were prepared as solid phase extraction adsorbents for selective enrichment of glycosides in soy products prior to quantitation by HPLC-UV. PMID- 29594570 TI - A colorimetric gold nanoparticle aggregation assay for malathion based on target induced hairpin structure assembly of complementary strands of aptamer. AB - The authors describe a method for the colorimetric determination of the pesticide malathion. It is based on the use of a hairpin structure consisting of a complementary strand of aptamer and a double-stranded DNA (dsDNA) structure to protect gold nanoparticles (AuNPs) against salt-induced aggregation. In the absence of malathion, the dsDNA structure is preserved on the surface of AuNPs and the color of the AuNPs in solutions containing NaCl remains red. However, in the presence of malathion, a hairpin structure of complementary strand is formed. The Aptamer/Malathion complex and the complementary strand are released from the surface of the AuNPs. As a result, the AuNPs undergo salt-induced aggregation which is accompanied by a color change to blue. The assay allows malathion to be quantified within 35 min (A650/A520 was measured). The detection limit is 1 pM, and response is linear in the 5 pM to 10 nM malathion concentration range. The method is specific and was successfully applied to the determination of malathion in spiked human serum samples. Graphical abstract Schematic representation of detection of malathion based on dsDNA-modified gold nanoparticles (AuNPs) and the hairpin structure of the complementary strand. PMID- 29594572 TI - ? PMID- 29594571 TI - Branched silver nanowires on fluorine-doped tin oxide glass for simultaneous amperometric detection of H2O2 and of 4-aminothiophenol by SERS. AB - This study introduces a two-step method for the deposition of branched silver nanowires (AgNWs) on fluorine-doped tin oxide (FTO) glass. This material serves as both an active surface-enhanced Raman-scattering (SERS) substrate and as an enzyme-free electrochemical sensor for H2O2. This dual functionality is systematically studied. The AgNWs as the main trunk were first deposited on FTO by spray-coating. Silver branches were then electrochemically produced on the preformed NWs. Scanning electron microscopy, X-ray diffraction and X-ray photoelectron spectrometry were employed to characterize morphology, composition and microstructure. SERS experiments show that the branched AgNW/FTO substrate exhibits excellent performance in detecting 4-aminothiophenol at an ultra-low concentration of 0.1 fM. Simultaneously, this material displays an excellent electrocatalytic response to H2O2 reduction at a concentration as low as 1 MUM. The sensor has a rapid response and two linear analytical ranges that extend from 0.25 to 300 MUM, and from 0.3 to 2.6 mM of H2O2, respectively. The ultrahigh sensitivity and satisfactory reproducibility highlights the merit of this hierarchical AgNW dendritic structure for sensing applications. Graphical abstract Branched silver nanowires can serve as both an active surface-enhanced Raman scattering substrate and as an electrochemical sensor for H2O2. This dual functionality is systematically investigated.

AB - A nanohybrid electrode was prepared by functionalizing reduced graphene oxide nanosheets (GNs) with gold nanoparticles (AuNP), CoS2, and an ionic liquid. It is shown to enable voltammetric determination of dopamine (DA). The AuNPs were electrodeposited onto the electrode that was first modified with CoS2 and the IL GNs to obtain a well-defined 3-dimensional and porous structure. The nanohybrid material displays high catalytic activity and an ultrasensitive cyclic voltammetric response to DA. The peak current (best measured at a working voltage of 0.17 V vs. Ag/AgCl) increases linearly in the 0.1 to 400 MUM DA concentration range, with a 40 nM detection limit (at S/N = 3). The electrode was successfully applied to the determination of DA in spiked serum samples. Graphical abstract Schematic of the preparation of a nanohybrid electrode odified with graphene oxide nanosheets functionalized with gold nanoparticles/CoS2/ionic liquid by electrodeposition.

PMID- 29594574 TI - Aptamer-based fluorescent platform for ultrasensitive adenosine detection utilizing Fe3O4 magnetic nanoparticles and silver nanoparticles. AB - The authors describe an aptamer-based fluorescent assay for adenosine (Ade). It is based on the interaction between silver nanoparticles (AgNPs) and CdTe quantum dots (QDs). The beacon comprises a pair of aptamers, one conjugated to Fe3O4 magnetic nanoparticles, the other to AgNPs. In the presence of Ade, structural folding and sandwich association of the two attachments takes place. After magnetic separation, the associated sandwich structures are exposed to the QDs. The AgNPs in sandwich structures act as the signaling label of Ade by quenching the fluorescence of QDs (at excitation/emission wavelengths of 370/565 nm) via inner filter effect, electron transfer and trapping processes. As a result, the fluorescence of QDs drops with increasing Ade concentration. The assay has a linear response in the 0.1 nM to 30 nM Ade concentration range and a 60 pM limit of detection. The assay only takes 40 min which is the shortest among the aptamer based methods ever reported. The method was successfully applied to the detection of Ade in spiked biological samples and satisfactory recoveries were obtained.

AB - The authors report on a surface-enhanced Raman scattering (SERS) nanoprobe for the specific detection of Escherichia coli O157:H7 (E. coli O157:H7). Gold nanoparticles (AuNPs) were coated with a thick silica shell, and the Raman reporter (4,4'-dipyridyl) was embedded between gold nanoparticle and silica shell. This technique prevents any external effects on the AuNPs from the environment and avoids any interaction between the Raman reporter and possible impurities. Compared to the SERS nanoprobe of the conventional AuNP/AgNP type, the present nanoprobe can be applied in complex biochemical circumstances without aggregation because of its excellent stability. The SERS nanoprobeis stable for up to 50 h. The probe was applied to the SERS detection of E. coli O157:H7 by exploiting the Raman band peaking at 1612 cm-1 of 4,4'-dipyridyl (DP). The limit of detection is as low as 10 CFU.mL-1. The technique was successfully employed to the detection of E. coli O157:H7 in real samples, achieving recoveries between 95.5 and 114.8%.

AB - The authors report on a loop-mediated isothermal amplification (LAMP) scheme that uses antarctic thermally sensitive uracil-DNA-glycosylase (AUDG) for simultaneous detection of nucleic acids and elimination of carryover contamination. It was applied in a lateral flow assay (LFA) format. The assay has attractive features in that it does not require the use of labeled primers or probes, and can eliminate false-positive results generated by unwanted hybridization between two labeled primers or between a labeled primer and probe. LAMP amplification and AUDG digestion are conducted in a single pot, and the application of a closed tube reaction prevents false-positives due to carryover contamination. The method was applied to the detection of the human pathogen Streptococcus pneumoniaein in pure cultures and spiked blood samples. This LFA can detect S. pneumoniae in pure cultures with a 25 fg.MUL-1 detection limit and in spiked blood samples with a 470 cfu.mL-1 detection limit. Conceivably, this assay can be applied to the detection of various other targets if the specific LAMP primers are available. Graphical abstract ?.

AB - Plant leaves (phyllosphere) have a great potential for colonization and microbial growth, consisting of a dynamic environment in which several factors can interfere with the microbial population structure. The use of genetically modified (GM) plants has introduced several traits in agriculture, such as the improvement of plant drought tolerance, as observed in the AtAREB1 transcription factor overexpression in soybean (Glycine max L. Merrill). The present study aimed at investigating the taxonomic and functional profile of the leaf microbial community of bacteria found in GM (drought-tolerant event 1Ea2939) and conventional (BR 16) soybean plants. Bacterial DNA was extracted from leaf samples collected from each genotype and used for microbial diversity and richness analysis through the MiSeq Illumina platform. Functional prediction was performed using the PICRUSt tool and the STAMP v 2.1.3 software. The obtainment of the GM event 1Ea2939 showed minimum effects on the microbial community and in the potential for chemical-genetic communication, i.e. in the potential for symbiotic and/or mutualistic interaction between plants and their natural microbiota.

AB - A colorimetric method is described for sensitive and low-cost detection of Cd(II). It is based on the use of triangular silver nanoplates (tri-AgNPs) modified with 1-amino-2-naphthol-4-sulfonate (ANS) acting as a colorimetric probe. ANS is first linked to the tri-AgNPs via electrostatic interaction of the sulfo groups. In the absence of analyte, ANS on the surface of tri-AgNPs protects them from aggregation. In the presence of Cd(II), the tri-AgNPs aggregate due to the interaction between ANS and Cd(II). This results in a distinct color change from blue (absorption peak at 710 nm) to green (peak at 770 nm). UV-vis spectrometry and image analyses demonstrate that this method exhibits selective and sensitive colorimetric response to Cd(II). The color change can be easily detected with bare eyes. Response is linear in the 30 to 70 MUM concentration range, and the detection limit is 30 nM. Graphical abstract A colorimetric method for sensitive, and low-cost detection of Cd(II) based on the use of tri-AgNPs modified with ANS acting as a colorimetric probe was presented.

AB - The authors report that cobalt oxyhydroxide (CoOOH) nanoflakes possess intrinsic oxidizing ability to directly oxidize 3,3',5,5'-tetramethylbenzidine (TMB) to form a blue colored product (oxTMB) even in the absence of H2O2 and oxygen. In the presence of ascorbic acid (AA), less of the blue product is formed because AA reduces oxTMB. These findings constitute a new scheme for colorimetric detection of AA. Absorbance, best measured at 652 nm, linearly drops in the 10 nM to 1 MUM AA concentration range, and the limit of detection is 5 nM (at an S/N ratio of 3). The reaction is complete within <5 s and highly selective. A strip test has been designed for fast and on-spot visual detection of AA. The method was applied to the direct estimation of AA in the microdialysate of brain, and also in soft drink samples. The strip test is considered to be a promising tool for the rapid screening of AA in brain and commercial samples.

AB - The authors describe a zinc-based metal-organic framework/polyethersulfone nanocomposite (TMU-4/PES) coating deposited on a stainless steel wire via a single-phase inversion method. The nanocomposite represents a novel fiber coating for headspace solid-phase microextraction of organophosphorous pesticides (OPPs) from environmental water and soil samples. The synergistic effects of the high surface area and unique porous structure of TMU-4 as well as the rich pi electron stacking and mechanical attributes of the PES polymer result in a high affinity of the composite for OPPs. Following thermal desorption, the OPPS were quantified by gas chromatography with a nitrogen-phosphorus detector. The preparation of the coating is simple, and the coated fiber is highly stable and reusable in that it can be used in about 100 consecutive extractions/desorption cycles. A central composite design was used for assessing the effect of the experimental parameters on the extraction process. Under optimized conditions, the limits of detection are in the 5-8 ng mL-1 range for the OPPs diazinon, fenitrothion, malathion and chlorpyrifos. The average repeatability and fiber-to-fiber reproducibility are 6.5% and 8.7%, respectively. The method was applied to the trace determination of OPPs in (spiked) water and soil samples where it gave good recovery (88-108%) and satisfactory reproducibility (5.9-10.1%).

AB - PURPOSE OF REVIEW: We review evidence for the potential importance of interoception, i.e., the processing of signals arising from inside the body, for deficient psychosocial functioning in borderline personality disorder (BPD). RECENT FINDINGS: Evidence suggests that variability in interoception interacts with higher-order psychological functions such as self, other, and emotion processing. These domains are characteristically impaired in BPD, suggesting a likely causal role of disturbed interoception in the etiology of the disorder. The inability to identify and describe one's own emotional states represents a proxy of impaired interoception which might further mediate between the perception of inner physiological conditions and psychosocial functioning in BPD. There is preliminary evidence explaining how early life stress might adversely affect central interoceptive representation and psychosocial functioning in BPD. Based on these findings and the specific pattern of disturbances in BPD, we propose the crucial role of interoception in an integrated biobehavioral model for BPD.

AB - The authors describe new bifunctional mesoporous silica nanoparticles (NPs) for specific targeting of tumor cells and for intracellular delivery of the cancer drug doxorubicin (DOX). Mesoporous silica nanoparticles (MSNPs) were coated with blue fluorescent N-graphene quantum dots, loaded with the drug DOX, and finally coated with hyaluronic acid (HA). Cellular uptake of the NPs with an architecture of the type HA-DOX-GQD@MSNPs enabled imaging of human cervical carcinoma (HeLa) cells via fluorescence microscopy. The cytotoxicity of the nanoparticles on HeLa cells was also assessed. The results suggest that the NPs are higher cytotoxicity effect and exert in living cell imaging ability. Compared to the majority of other drug nanocarrier systems, the one described here enables simultaneous DOX release and fluorescent monitoring. Graphical abstract Schematic of the bifunctional mesoporous silica nanoparticles were obtained via the Stober method, along with the doxorubicin loaded and the hyaluronic acid capped. The sensor shows good specificity and significant cytotoxicity effect on Hela cells. (TEOS: tetraethyl orthosilicate; GQDs: graphene quantum dots; DOX: doxorubicin; HA: Hyaluronic acid).

AB - The authors describe a method that can significantly improve the performance of impedimetric detection of bacteria. A multifunctional microfluidic chip was designed consisting of interdigitated microelectrodes and a micro-mixing zone with a Tesla structure. This maximizes the coating of bacterial surfaces with nanoparticles and results in improved impedimetric detection. The method was applied to the detection of Escherichia coli O157:H7 (E. coli). Silver enhancement was accomplished by coating E.coli with the cationic polymer diallyldimethylammonium chloride (PDDA) to form positively charged E. coli/PDDA complexes. Then, gold nanoparticles (AuNPs) were added, and the resulting E. coli/PDDA/AuNPs complexes were collected at interdigitated electrodes via positive dielectrophoresis (pDEP). A silver adduct was then formed on the E. coli/PDDA/AuNP complexes by using silver enhancement solutions and by using the AuNPs as catalysts. The combination of pDEP based capture and of using silver adducts reduces impedance by increasing the conductivity of the solution and the double layer capacitance around the microelectrodes. Impedance decreases linearly in the 2 * 103-2 * 105 cfu.mL-1 E. coli concentration range, with a 500 cfu.mL-1 detection limit. Egg shell wash samples and tap water spiked with E. coli were successfully used for validation, and this demonstrates the practical application of this method. Graphical abstract Schematic representation of the AuNP@Ag enhancement method integrated with multifunctional microfluidic chip platform for impedimetric quantitation of bacteria. The method significantly improves the performance of impedimetric detection of bacteria.

AB - The authors describe an analytical detection scheme based on the use of multiwalled carbon nanotubes (MWCNTs) that accept and store electrons upon contact with photo-irradiated TiO2 nanoparticles (TiO2-NPs). The Fermi level equilibration with photo-irradiated TiO2-NPs has a storage value of 0.35 mM of electrons per 120 mg.L-1 of MWCNTs. The stored electrons can be discharged on demand upon addition of electron acceptors to the TiO2-NP/MWCNT composite. These findings are applied to detect the quencher hydrogen peroxide. H2O2 also is produced on enzymatic action of glucose oxidase on glucose, and this enables glucose also to be quantified by using the TiO2-NP/MWCNT fluorescent nanoprobe. The wide scope of the method also is demonstrated by an assay for aflatoxin B1 that is making use of an FAM-labeled aptamer where the FAM fluorophore on the aptamer quenches the emission of the nanoprobe. The following analytical linear ranges and limits of detection are found: H2O2: 0.1-100 MUM and 15 nM; glucose: 5 200 MUM and 0.5 MUM; aflatoxin: 0.1-40 ng.mL-1 and 0.02 ng.mL-1. The method was applied to the determination of glucose in human serum. Graphical abstract The assays demonstrated in (b) and (c) are based on the fluorescence quenching ability of MWCNTs-TiO2. In the presence of the target (analyte), the fluorescence is restored and the target concentration is determined from the percentage of fluorescence recovery. PMID- 29594584 TI - Genital marginal failures after intensity-modulated radiation therapy (IMRT) in squamous cell anal cancer: no higher risk with IMRT when compared to 3DCRT. AB - Intensity-modulated radiotherapy (IMRT) is considered the preferred option in squamous cell canal cancer (SCAC), delivering high doses to tumor volumes while minimizing dose to surrounding normal tissues. IMRT has steep dose gradients, but the technique is more demanding as deep understanding of target structures is required. To evaluate genital marginal failure in a cohort of patients with non metastatic SCAC treated either with IMRT or 3DCRT and concurrent chemotherapy, 117 patients with SCAC were evaluated: 64 and 53 patients were treated with IMRT and 3DCRT techniques, respectively. All patients underwent clinical and radiological examination during their follow-up. Tumor response was evaluated with response evaluation criteria in solid tumors v1.1 guideline on regular basis. All patients' data were analyzed, and patients with marginal failure were identified. Concomitant chemotherapy was administered in 97 and 77.4% of patients in the IMRT and 3DCRT groups, respectively. In the IMRT group, the median follow up was 25 months (range 6-78). Progressive disease was registered in 15.6% of patients; infield recurrence, distant recurrence and both infield recurrence and distant recurrence were identified in 5, 4 and 1 patient, respectively. Two out of 64 patients (3.1%) had marginal failures, localized at vagina/recto-vaginal septum and left perineal region. In the 3DCRT group, the median follow-up was 71.3 months (range 6-194 months). Two out of 53 patients (3.8%) had marginal failures, localized at recto-vaginal septum and perigenital structures. The rate of marginal failures was comparable in IMRT and 3DCRT groups (chi2 test p = 0.85). In this series, the use of IMRT for the treatment of SCAC did not increase the rate of marginal failures offering improved dose conformity to the target. Dose constraints should be applied with caution-particularly in females with involvement of the vagina or the vaginal septum. PMID- 29594586 TI - A cationic conjugated polymer coupled with exonuclease I: application to the fluorometric determination of protein and cell imaging. AB - A strategy is described for the detection of protein by using a cationic fluorescent conjugated polymer coupled with exonuclease I (Exo I). Taking streptavidin (SA) as model protein, it is observed that Exo I can digest single stranded DNA conjugated with biotin and carboxyfluorescein (P1) if SA is absent. This leads to the formation of small nucleotide fragments and to weak fluorescence resonance energy transfer (FRET) from the polymer to P1. If, however, SA is present, the high affinity of SA and biotin prevents the digestion of P1 by Exo I. This results in the sorption of P1 on the surface of the polymer through strong electrostatic interaction. Hence, efficient FRET occurs from the fluorescent polymer to the fluorescent label of P1. Fluorescence is measured at an excitation wavelength of 370 nm, and emission is measured at two wavelengths (530 and 425 nm). The ratio of the two intensities (I530/I425) is directly related to the concentration of SA. Under the optimal conditions, the assay has a detection limit of 1.3 ng.mL-1. The method was also applied to image the folate receptor in HeLa cells, thus demonstrating the versatility of this strategy. Graphical abstract A fluorometric strategy is described for protein detection and cell imaging based on a cationic conjugated polymer (PFP) coupled with exonuclease I (Exo I) trigged fluorescence resonance energy transfer (FRET).

The GSH-Au/AgNCs have two emissions at 616 nm and 412 nm when excited at 360 nm. With the increased concentration of Cys, the ratio of the emission intensities (I616/I412) linearly decreases with Cys in concentration ranging from 0.05 to 10 MUM and from 10 to 50 MUM, respectively. With increased concentrations of Arg, the ratio of I616/I412 linearly decreases with Arg concentration ranging from 0 to 50 MUM and from 50 to 100 MUM, respectively.

AB - An optical method is described for the quantitation of glucose by using oxygen deficient alpha-MoO3-x nanoflakes. It is based on the use of glucose oxidase (GOx) which produces hydrogen peroxide on oxidation of glucose. Hydrogen peroxide then oxidizes the alpha-MoO3-x nanoflakes, and this results in a visible color change from blue to colorless. The color change can be measured photometrically at 740 nm. The method has a 68 nM detection limit. Graphical Abstract Mechanism of glucose detection using blue colored oxygen deficient 2D alpha-MoO3-x nanoflakes. Hydrogen peroxide (H2O2) is formed as a by-product in the conversion of glucose to glucono-1,5-lactone by glucose oxidase (GOx). In the presence of H2O2, the oxygen vacancies in alpha-MoO3-x nanoflakes are filled up, and this leads to the loss of blue color of the nanoflakes because they are converted back to colorless bulk alpha-MoO3.

AB - An electrochemical sensor is described for the determination of L-tryptophan (TRP). The method is based on the use of a glassy carbon electrode (GCE) modified with a nanocomposite consisting of moss ball-like cerium-doped ZnO and functionalized multiwalled carbon nanotubes (Ce-ZnO/f-MWCNT). Ce-doped ZnO was synthesized by a low temperature hydrothermal method. The Ce-ZnO/f-MWCNT nanocomposite was characterized by X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, FTIR and field emission scanning electron microscopy. The nanocomposite was drop cast on a GCE for use in electrochemical detection of TRP via cyclic voltammetry and differential pulse voltammetry. The oxidation peak current (0.76 V vs. Ag/AgCl) is strongly improved compared to a bare GCE. The experimental parameters such as solution pH value, scan rate, stability, concentration, reproducibility and repeatability were optimized. Response is linear in the 10 to 100 nM TRP concentration range, the limit of detection is 1.2 nM, and the sensitivity is 2.59 MUA.nM-1.cm-2. The electrode was applied to the determination of TRP in spiked real samples and gave satisfactory results.

PMID- 29594590 TI - Aptamer based vanillin sensor using an ion-sensitive field-effect transistor. AB - An aptamer for vanillin was obtained and then used for the development of an aptasensor based on an ion-sensitive field-effect transistor (ISFET). This aptamer (a single-stranded DNA;ssDNA) was selected using the Capture-SELEX protocol, which suites well for selection of aptamers to small molecules. Among six aptamer candidates, the aptamer Van_74 with the highest affinity for vanillin was chosen (elution of 35% of the aptamer from a solid support in the presence of 2 mM of vanillin). Van_74 was characterized using nondenaturating PAGE of washouts from magnetic beads. It is shown that Van_74 binds to vanillin with an dissociation constant of >7.8 MUM (determined by nondenaturating PAGE) and it was specific to vanillin in comparison with interferents: benzaldehyde, guaiacol, furaneol, ethyl guaiacol and ethyl vanillin. Also it was shown that change of buffer composition greatly affected the binding ability of Van_74. For biosensor fabrication aptamer was immobilised on the Ta2O5-sensitive surface of the ISFET via "click-chemistry". Detection scheme implied dehybridisation of the ssDNA probe from the aptamer and release in the solution during the addition of vanillin. As a result, the surface potential increase upon vanillin binding with the aptamer was detected by the transistor. The biosensor had a detection limit of 1.55 * 10-7 M and a dynamic range from 1.55 * 10-7 M to 1 * 10-6 M. Effective constant Kd,eff for vanillin binding on biosensor surface was calculated to be (9 +/- 3) * 10-7 M. This allows selective detection of vanillin in the mixture of interferents and in samples of coffee extract. Graphical abstract A biosensor for vanillin was developed on the basis of an aptamer that was obtained via Capture SELEX and by using an ISFET. This biosensor can be used for vanillin detection in presence of interferents and in real sample using an approach of ssDNA probe dehybridization.

AB - Carbon dots doped with sulfur and nitrogen (S,N-CDs) were utilised to design a paper-stripe based fluorescent probe for the detection of bilirubin. The S,N-CDs were synthesized through a microwave assisted route by using citric acid as carbon source and L-cysteine as a source of nitrogen and sulfur. The S,N-CDs exhibit bright blue fluorescence emission with a peak at 452 nm. Fluorescence is quenched by Fe(III) but selectively restored by bilirubin. The quenched fluorescent probe exhibit significant selectivity and sensitivity for bilirubin in the 0.2 nM to 2 nM concentration range, with a 0.12 nM detection limit.

The method was used to design a paper based test stripe as a point of care device for visual bilirubin detection. Graphical abstract Schematic representation of sulphur and nitrogen doped carbon dots whose fluorescence is quenched by Fe(III) and turned on by bilirubin.

AB - The Mycobacterium Ag85 complex is the major secretory protein of M. tuberculosis. It is a potential marker for early diagnosis of tuberculosis (TB). The authors have identified specific aptamers for Ag85A (FbpA) via protein SELEX using magnetic beads. After twelve rounds of selection, two aptamers (Apt8 and Apt22) were chosen from different groups, and their binding constants were determined by flow cytometry. Apt22 (labeled with Atto 647N) binds to FbpA with high affinity (Kd = 63 nM) and specificity. A rapid, sensitive, and low-cost fluorescent assay was designed based on the use of Apt22 and graphene oxide, with a limit of detection of 1.5 nM and an analytical range from 5 to 200 nM of FbpA.

AB - The authors describe an electrochemical method for aptamer-based determination of insulin at femtomolar concentrations. The surface of a screen printed electrode was modified with ordered mesoporous carbon that was chemically modified with 1,3,6,8-pyrenetetrasulfonate (TPS). The amino-terminated aptamer was then covalently linked to TPS via reactive sulfonyl chloride groups. Subsequently, the redox probe Methylene Blue (MB) was interacted into the aptamer. The MB-modified binds to insulin and this results in the release of MB and a decreased signal as obtained by differential pulse voltammetry, best at a working voltage of -0.3 V (versus silver pseudo-reference electrode). Insulin can be quantified by this method in the 1.0 fM to 10.0 pM concentration range, with a 0.18 fM limit of detection (at 3sigma/slope). The assay was applied to the determination of insulin in spiked human serum samples. The method is highly sensitive, selective, stable, and has a wide analytical range.

PMID- 29594594 TI - A lateral flow assay for the determination of human tetanus antibody in whole blood by using gold nanoparticle labeled tetanus antigen. AB - The authors describe a lateral flow assay (LFA) for the antibody against the infectious bacterium Clostridium tetani. Gold nanoparticles (AuNPs) were linked to tetanus antigen and are captured in the test line via the formation of a sandwich structure composed of AuNP-labeled tetanus antigen, tetanus antibody, and tetanus antigen. This leads to the formation of a characteristic red line due to the accumulation of AuNPs. The formation of the color line allows for a highly sensitive and selective detection of tetanus antibody, both with bare eyes and by smartphone-based quantitative analysis. This assay offers a wide detection range from 0 to 0.5 IU.mL-1 and has a linear relationship from 0.01 to 0.1 IU.mL-1 with an experimental detection limit of 0.01 IU.mL-1. This assay is simple, fast, inexpensive and highly selective. When applied to the detection of tetanus antibody in spiked whole blood, it provided reliable results that compared well to those obtained with a commercial ELISA kit. Graphical abstract ?.

AB - PURPOSE OF REVIEW: To discuss the current state of glioma vaccine development and highlight the challenges associated with clinical implementation of these approaches. RECENT FINDINGS: Vaccination strategies against gliomas have matured considerably during the past years, although proof-of efficacy from controlled clinical trials is still lacking. Advances in antigen discovery, including the definition of neoepitopes including epidermal growth factor receptor variant III (EGFRvIII), isocitrate dehydrogenase (IDH)1R132H and Histone (H)3.3K27M, using multi-omic approaches and computational algorithms allow targeting single antigens, but also implementing truly personalized approaches. In addition, new concepts of vaccine manufacturing including RNA and DNA vaccines improve immunogenicity and applicability in personalized settings. As an increasing amount of clinical data defy the concept of the central nervous system (CNS) as a strictly immunoprivileged site, novel vaccine approaches enter the clinic including critical efforts to identify biomarkers of response and resistance and strategies to overcome the immunosuppressive glioma microenvironment.

AB - The authors introduce a new kind of surface artificial biomimetic receptor, referred to as aptameric imprinted polymer (AIP), for separation of biological macromolecules. Highly dispersed magnetic nanoparticles (MNPs) were coated with silica and then functionalized with methacrylate groups via silane chemistry. The aptamer was covalently immobilized on the surface of nanoparticles via a "thiol ene" click reaction. Once the target analyte (bovine serum albumin; BSA) has bound to the aptamer, a polymer is created by 2-dimensional copolymerization of short-length poly(ethylene glycol) and (3-aminopropyl)triethoxysilane. Following removal of BSA from the polymer, the AIP-MNPs presented here can selectively capture BSA with a specific absorbance (kappa) as high as 65. When using this AIP, the recovery of BSA from spiked real biological samples is >97%, and the adsorption capacity is as high as 146 mg g-1. In our perception, this method has a wide scope in that it may be applied to the specific extraction of numerous other biomolecules.

AB - A nanoprobe is described for the ratiometric fluorometric determination of sulfite ions. Upconversion nanoparticles (UCNPs) of the type beta NaYF4:Yb(III),Er(III),Tm(III) were covalently modified with the molecular probe HIAN which is a hydroxynaphthalimide fluorophore modified with a (cationic) indolinium moiety. Under excitation at 980 nm, the green emission of the UCNPs (peaking at 543 nm) is almost totally quenched, while the NIR emission (peaking at 802 nm) remains unaffected. In the presence of sulfite or bisulfite (hydrogen sulfite), the green fluorescence is restored and can be visually observed. A ratiometric method was worked out by measurement of the ratio of the green and NIR emissions. The analytical range extends from 10 to 250 MUM, the limit of detection is 0.14 MUM, and the assay can be performed within 40 s.

AB - A glassy carbon electrode (GCE) was modified with multi-walled carbon nanotubes (MWCNT) and silver nanoparticles (AgNPs) and applied to the simultaneous determination of hydroquinone (HQ), catechol (CC), bisphenol A (BPA) and phenol by using square-wave voltammetry. The MWCNTs were deposited on the GCE and the AgNPs were then electrodeposited onto the MWCNT/GCE by the application of 10 potential sweep cycles using an AgNP colloidal suspension. The modified GCE was characterized by using SEM, which confirmed the presence of the AgNPs. The electrochemical behavior of the material was evaluated by using cyclic voltammetry, and by electrochemical impedance spectroscopy that employed hexacyanoferrate as an electrochemical probe. The results were compared to the performance of the unmodified GCE. The modified electrode has a lower charge transfer resistance and yields an increased signal. The peaks for HQ (0.30 V), CC (0.40 V), BPA (0.74 V) and phenol (0.83 V; all versus Ag/AgCl) are well separated under optimized conditions, which facilitates their simultaneous determination. The oxidation current increases linearly with the concentrations of HQ, CC, BPA and phenol. Detection limits are in the order of 1 MUM for all 4 species, and the sensor is highly stable and reproducible. The electrode was successfully employed with the simultaneous determination of HQ, CC, BPA and phenol in spiked tap water samples.

AB - A magnetized molecularly imprinted polymer (MIP) was prepared via a surface imprinting technique. An allyl-based deep eutectic solvent was chosen as the functional monomer to obtain the polymer for specific recognition of lysozyme. It was deposited on silica-coated magnetite nanoparticles. The structure of the polymer was confirmed by X-ray diffraction, Fourier transform infrared spectrometry, transmission electron microscopy, thermogravimetric analysis and vibrating sample magnetometry. The maximum binding capacity of the imprinted polymer is found to be 108 mg.g-1, which is higher than that of non-imprinted polymer. Compared to reference proteins such as cytochrome C, bovine hemoglobin and bovine serum albumin, the MIP shows favorable selectivity for lysozyme. Besides, the imprinted polymer can be further used to specifically recognize lysozyme from the protein mixture and chicken egg white. Reusability studies demonstrate that the polymer can be recycled four times without significant loss of adsorption capacity. The LOD of the method is 12.8 MUg.mL-1. The relative standard deviations (for n = 3) are 1.38% for precision and 2.76% for repeatability. Its facile synthesis, high adsorption performance and excellent selectivity to capture lysozyme make this polymer an attractive candidate to be applied in biomacromolecular purification.

AB - Porphyromonas gingivalis (P. gingivalis) is a pathogen causing periodontitis. A rapid assay is described for the diagnosis of periodontal infections related to P. gingivalis. The method is making use of gingipains, a group of P. gingivalis specific proteases as a detection biomarker. Magnetic-nanobeads were labeled with gingipain-specific peptide substrates and immobilized on a gold biosensing platform via gold-thiol linkage. As a result of this, the color of the gold layer turns black. Upon cleavage of the immobilized substrates by gingipains, the magnetic-nanobeads-peptide fragments were attracted by a magnet so that the golden surface color becomes visible again. This assay is highly sensitive and specific. It is capable of detecting as little as 49 CFU.mL-1 of P. gingivalis within 30 s. Examination of periodontitis patients and healthy control saliva samples showed the potential of the assay. The simplicity and rapidity of the assay makes it an effective point-of-care device.

The experimental conditions for fiber coating, extraction, stirring rate, ionic strength, pH value, desorption temperature and time were optimized. Following thermal desorption, the pesticides were quantified by GC-MS. Under optimum conditions, the repeatability (RSD) for one fiber (for n = 3) ranges from 4.3 to 5.6%. The detection limits are between 8 and 12 pg mL-1. The method is fast, inexpensive (in terms of equipment), and the fiber has high thermal stability.

They were then quantified by gas chromatography-mass spectrometry.

AB - A carbon electrode modified with the ionic liquid octylpyridinium hexafluorophosphate and copper hydroxide nanoparticles was employed in an electrochemical assay for simultaneous determination of captopril (CPT) and hydrochlorothiazide (HCT). The electrode showed two well-defined oxidation peaks for CPT (at 0.22 V) and HCT (at 0.73 V, both vs. Ag/AgCl) at pH 8.0 using square wave voltammetry. Calibration plots are linear in the concentration ranges of 0.7 70 uM (CPT) and 3-600 MUM (HCT), with detection limits of 12 and 60 nM, respectively. The electrode was repeatedly applied to simultaneous determination of CPT and HCT in pharmaceutical formulation without showing any fouling. Graphical abstract Application of carbon ionic liquid electrode (CILE) modified with Cu(OH)2 nanoparticles (Cu(OH)2NP/CILE) for the simultaneous determination of captopril (CPT) and hydrochlorothiazide (HCT) in pharmaceutical formulation is presented. PMID- 29594605 TI - Autonomic nervous system and cancer. AB - The autonomic nervous system (ANS) is the main homeostatic regulatory system of the body. However, this widely distributed neural network can be easily affected by cancer and by the adverse events induced by cancer treatments. In this review, we have classified the ANS complications of cancer into two categories. The first includes direct cancer-related complications, such as primary ANS tumors (pheochromocytoma, paraganglioma or neuroblastoma), as well as autonomic manifestations induced by non-primary ANS tumors (primary brain tumors and metastases). The second comprises indirect ANS complications, which include autonomic features related to cancer therapy (chemotherapy, radiotherapy and/or surgery) and those not related to cancer therapy, such as paraneoplastic autonomic syndromes. We also review the molecular relationship and modulation between the ANS and the cancer cells and their microenvironment. PMID- 29594607 TI - Graphitic carbon nitride nanosheets as a fluorescent probe for chromium speciation. AB - A fluorometric method was developed for simultaneous determination of Cr(VI) and Cr(III) ions using graphitic carbon nitride nanosheets (g-C3N4 NS) as a nanosized fluorescent indicator probe. The g-C3N4 NS were prepared using high-temperature carbonization of melamine followed by ultrasonication-assisted liquid exfoliation. The g-C3N4 NS display fluorescence with excitation/emission peaks located at 320 and 450 nm. The chromium speciation is based on the quenching of g C3N4 NS fluorescence. The total concentration of chromium is determined after oxidation of Cr(III) to Cr(VI). The Cr(III) content was then calculated by subtracting the concentration of Cr(VI) from that of total chromium. The effects of pH value, probe amount, and contact time are optimized. Under optimum conditions, calibration plots are linear in the range in the 0.01 to 100 MUM chromium concentration range. The limit of detection is 3 nM for for Cr(VI). The intra- and inter-day relative standard deviations (RSD) of the assay are 3.6-7.5% and 4.1-8.5%, respectively. The indicator probe was applied to the determination of chromium species in spiked water and food samples, and recoveries were satisfactory (93.9-107.0%). Graphical abstract Graphitic carbon nitride nanosheets are synthesized by melamine carbonization and employed for Cr speciation in water and food real samples. Total Cr(VI) and Cr(VI) are assessed based on the quenching of the fluorescence of nanosheets by Cr(VI). PMID- 29594608 TI - Electrochemiluminescence based detection of microRNA by applying an amplification strategy and Hg(II)-triggered disassembly of a metal organic frameworks functionalized with ruthenium(II)tris(bipyridine). AB - An electrochemiluminescence (ECL) biosensor is described for the detection of microRNA (miRNA-155) based on tris(bipyridine)ruthenium(II) functionalized metal organic framework (RuMOF) materials. The material was prepared by a solvothermal method and was found to be stable even in acidic solution. However, it is selectively and sensitively disassembled by Hg(II) ions, resulting in the release of large quantities of Ru(II)(bpy)3 ions, which produces a strong ECL signal. In view of the ion-selective disassembly and release and strand displacement process, an ultrasensitive ECL sensing method was established for detection of microRNAs. In the presence of the target, the hairpin structure of H1 can open and hybridize with the hairpin probe H2 to form a more stable H1-H2 duplex structure than the H1-target hybrid. The target of hybridization to H1 was immediately freed from the structure and the released target re-entered the new hairpin assembly target recovery process. The remaining H2 single fragment can bind to the I-RuMOFs-conjugates. The more hairpin probes H1, the more I-RuMOFs conjugates load the DNA fragments, leading to the signal amplification. The method works in the 0.8 f. to 1.0 nM miRNA-155 concentration range and has a detection limit of 0.3 fM. The assay is sensitive, fairly specific and remarkably stable. In our perception, it offers an attractive tool for the sensitive detection of microRNAs in clinical samples. Graphical abstract An electrochemiluminescence (ECL) based biosensor is described for the detection of microRNA (miRNA-155) based on the use of a metal organic framework functionalized with ruthenium(II)tris(bipyridine) that was deposited on a glassy carbon electrode (GCE) modified with gold nanoparticles. PMID- 29594609 TI - Reliability of a commercially available heterochromatic flicker photometer, the MPS2, for measuring the macular pigment optical density of a Japanese population. AB - PURPOSE: The macular pigment optical density (MPOD) of a Japanese population was measured using a commercially based heterochromatic flicker photometer, the Macular Pigment Screener (MPS2). The objective of the study was to evaluate the accuracy and test-retest reliability of the MPS2 in Asian pigmented eyes. STUDY DESIGN: Experimental study to validate the medical instrument in humans. METHODS: Twenty-four healthy Japanese participants with no systemic or eye diseases (men: 13, women: 11; mean [SD] age 38.6 [10.9 years]) were included. The concordance of the MPOD, obtained using the MPS2 and Macular Metrics II (MM2), and the test retest reliability were examined. RESULTS: Determination of the MPOD was unsuccessful in 1 participant; thus, the MPOD of 23 participants was analyzed. The mean (SD) MPOD measured with the detail-mode of the MPS2 was 0.63 (0.18) and with that of the MM2, it was 0.72 (0.23). The former was significantly lower than the latter (P = .003, paired t test). The MPOD measured with the MPS2 and the MM2 showed good concordance (r = 0.79, P < .001, Pearson product moment correlation). Bland-Altman analyses showed no systematic errors between the MPS2 and the MM2. The intraclass correlation coefficient over 5 measurement times with the detail mode of the MPS2 was 0.80, and the mean coefficient of variation was 9.4%. CONCLUSION: The high concordance with the MM2 and good test-retest reliability found by this study suggest that the MPS2 is acceptable for use in a Japanese population. However, the mean MPOD yielded by the MPS2 was significantly lower than that yielded by the MM2. Therefore, the MPS2 and MM2 are not interchangeable in a single study. PMID- 29594610 TI - Extended field imaging using swept-source optical coherence tomography angiography in retinal vein occlusion. AB - PURPOSE: To evaluate the degree of ischemia in eyes with retinal vein occlusion (RVO) using swept-source optical coherence tomography angiography (SS-OCTA) with the extended field imaging (EFI) technique, which extends the area encompassed by SS-OCTA by scanning through trial frames fitted with a +20-diopter lens. STUDY DESIGN: Retrospective observational study. METHODS: Twenty-three consecutive eyes of 22 patients with RVO underwent 12 * 12 mm SS-OCTA imaging both with and without EFI for determination of extension rate. Two graders blinded to the clinical data evaluated the degree of retinal ischemia in paired EFI-SS-OCTA and fluorescein angiography (FA) images, and the concordance rates between the grades were statistically examined. RESULTS: One EFI-SS-OCTA image was not successfully obtained due to motion artifacts caused by the patient's poor central vision, while SS-OCTA images without EFI were captured in all 23 eyes. The average extension rate of EFI-SS-OCTA over SS-OCTA was 1.39 +/- 0.06 and the average scanning area was enlarged by 76.4%. Two graders evaluated the degree of retinal ischemia by measuring nonperfusion areas as the sum of disc areas/diameters. Although their assessments of the EFI-SS-OCTA images were in complete agreement (Cohen's Unweighted Kappa coefficient = 1.00), concordance using FA images was only moderate (Cohen's Unweighted Kappa coefficient = 0.60). CONCLUSION: EFI-SS OCTA noninvasively produces wider field images of retinal vasculature with one capture and provides resolution sufficient to accurately evaluate retinal capillary nonperfusion in RVO. PMID- 29594611 TI - Phenotypic plasticity may help lizards cope with increasingly variable temperatures. AB - Temperature variability is predicted to increase in the coming century due to climate change. However, the biological impact of increased temperature variability on animals remains largely unexplored. Here, we experimentally exposed gravid viviparous lizards (Eremias multiocellata) to two thermal environments [constant daily maximum (CDM) versus variable daily maximum (VDM) treatment with the same average temperature] to address maternal and offspring responses to increased variability in ambient temperature. Females from the VDM treatment delayed parturition, but produced similar litter sizes and litter masses as did CDM females. Offspring from the VDM treatment selected higher body temperatures, had higher metabolic rates and higher growth rates, and grew to a similar size as those from the CDM treatment despite having a shorter growth period prior to hibernation. Therefore, phenotypic plasticity may be critical for lizards to respond effectively to climate change, and its role in responding to increasingly variable temperatures warrants further attention. PMID- 29594612 TI - Correction to: System productivity alters predator sorting of a size-structured mixed prey community. AB - There was an error in the abstract of the original publication. The 9th sentence of abstract should be:"Our results are inconsistent with predictions about the sorting effects of predators across productivity gradients because the more resistant prey dominated at low productivity." PMID- 29594613 TI - Mosquito responses to trait- and density-mediated interactions of predation. AB - Mosquito and predatory larvae often share the same habitat. Predators may influence mosquito prey populations through both lethal effect and non-lethal pathways. A series of experimental manipulations were used to distinguish between lethal (density-mediated interaction) and non-lethal (trait-mediated interaction) effects in a model system comprised of invasive prey mosquito, Aedes aegypti, and a predatory mosquito Toxorhynchites rutilus. Treatments with predators present or manipulations mimicking daily mortality (density reduction) reduced developmental time and recruitment to the adult stage. Daily records of adult survival of A. aegypti showed that exposure to predators during the juvenile stage shortened the lifespan of adults. This was also observed in treatments, where A. aegypti were replaced at the rate of consumption by T. rutilus. In contrast, numerical reductions in A. aegypti that mimicked daily rate of predation led to adults with the longest lifespan. These observations suggest strong effects of density and trait-mediated interactions in the influence of predators on mosquito biology relevant to their ability to transmit pathogens. These results have potentially important implications for disease control strategies. The primary approach to reduce risk of mosquito-borne diseases is through population reduction of the vectors. We show an unanticipated benefit of biological control by predation for the control of juvenile stages of mosquitoes. Specifically, mosquitoes that are exposed to predators but survive to adulthood will have compromised life expectancy, a key parameter in determining risk of disease transmission. PMID- 29594614 TI - Changes in plant growth and seed production in wild lima bean in response to herbivory are attenuated by parasitoids. AB - Lima bean plants (Phaseolus lunatus) exhibit compensatory growth responses to herbivory. Among the various factors that have been identified to affect plant compensatory growth are the extent and type of tissue damage, the herbivore's feeding mode and the time of damage. Another factor that can greatly impact plant responses to herbivory, but has been largely ignored in previous studies, is the action of parasitoids. In most cases, parasitoids halt or slow down the development of herbivorous hosts, which, can result in decreased leaf damage, thereby affecting plant responses and ultimately plant fitness. Here, we investigated the effects of two koinobiont parasitoids on the amount of leaf damage inflicted by the Southern armyworm Spodoptera latifascia to wild lima bean, and the consequences of this for plant growth and seed production in the field. We specifically tested the hypothesis that the action of parasitoids will reduce plant damage and that this reduction will alter plant growth responses and seed production. Indeed, we found that in the presence of parasitoids plants suffered less damage than plants with only herbivores. As a consequence, compensatory growth was reduced and more and heavier seeds were produced earlier in the season, compared to plants exposed to only herbivores. PMID- 29594615 TI - Two-dimensional MoS2 as a nano-binder for ssDNA: Ultrasensitive aptamer based amperometric detection of Ochratoxin A. AB - Two-dimensional (2D) MoS2 is found to possess different affinities for ssDNA and dsDNA. This finding is exploited in an amperometric aptamer-based method for the determination of the mycotoxin ochratoxin A (OTA). Initially, a dsDNA probe (formatted through the hybridization of OTA-aptamer with an auxiliary DNA) is self-assembled on a gold electrode. Upon introduction of OTA, it will bind to the aptamer and cause the unwinding of dsDNA, while the auxiliary DNA (with single stranded structure) remains on the electrode. Since the affinity of 2D MoS2 for ssDNA is considerably larger than that for dsDNA, it will be adsorbed on the electrode by binding to the auxiliary DNA. Notably, 2D MoS2 possesses peroxidase like activity. Hence, it can catalyze the amplification of electrochemical signal of the hydroquinone/benzoquinone redox system. Under optimal conditions, the amperometric signal (best measured at -0.2 V vs. SCE) increases with increasing OTA concentration in the range from 0.5 pg.mL-1 to 1.0 ng.mL-1, with a lower detection limit of 0.23 pg.mL-1. The method was applied to the determination of OTA in spiked red wine. Graphical abstract Herein we construct a convenient electrochemical aptasensor for sensitive monitor of ochratoxin A by using 2D MoS2 as a nano-binder to catalyze the amplification of electrochemical signal from hydroquinone/benzoquinone system. PMID- 29594616 TI - 3-Dimensional hollow graphene balls for voltammetric sensing of levodopa in the presence of uric acid. AB - The development of novel nanomaterials brings new opportunity and challenge for high sensing detection of biomolecules. The authors describe the preparation of 3 dimentional hollow graphene balls (3D HGBs) using nickel nanoparticles (Ni-NPs) as the template. The Ni-NPs were synthesized by chemical reduction of nickel chloride and then graphene was coated onto their surface via carburization and carbonization. After etching Ni-NPs, 3D HGBs with few layers and a typical size of 100 nm were obtained. They were sprayed onto indium tin oxide glass to obtain a working electrode for electrochemical determination of levodopa in the presence of uric acid. Due to the unique hollow porous structure of the 3D HGBs, the electrode exhibits a sensitivity of 0.69 MUA.MUM-1.cm-2 and a 1 MUM limit of detection. It is selective, reproducible and stable. It was applied to the determination of levodopa in spiked human plasma samples and it is of potential use in clinical research. Graphical abstract Schematic presentation of the preparation of 3-dimensional hollow graphene balls (HGBs) by using nickel nanoparticles as a template that can be removed by etching. The HGBs were sprayed onto indium tin oxide (ITO) glass to obtain a working electrode that has a sensitivity of 0.69 MUA?MUM-1.cm-2 and a 1 MUM limit of detection for the determination of levodopa. PMID- 29594617 TI - Fluorescence polarization gene assay for HIV-DNA based on the use of dendrite modified gold nanoparticles acting as signal amplifiers. AB - The authors describe a fluorescence polarization assay for HIV-DNA. It is based on the use of gold nanoparticles (AuNPs) modified with DNA dendritic macromolecules that act as signal amplifiers. In the presence of HIV-DNA, the AuNP-DNA dendritic macromolecules and fluorescently labeled DNA probe combine with HIV-DNA in a sandwich format to form a conjugate. This reaction slows down the rotational speed of the labeled DNA probe because of the increase of molecular weight and volume. This increases fluorescence polarization and the sensitivity of the system. The relative fluorescence polarization values increase linearly in the 150 pM to 6 nM HIV-DNA concentration range, with a 73 pM detection limit. The results show this amplification strategy to be most useful for ultrasensitive determination of oligonucleotides by means of fluorescence polarization. Graphical abstract Schematic of a novel fluorescence polarization assay for the HIV-DNA. Ultrasensitive detection is accomplished by using AuNP-DNA dendritic macromolecules as signal amplification factor. PMID- 29594618 TI - Mobile Phone Questionnaires for Sexual Risk Data Collection Among Young Women in Soweto, South Africa. AB - Recall and social desirability bias undermine self-report of paper-and-pencil questionnaires. Mobile phone questionnaires may overcome these challenges. We assessed and compared sexual risk behavior reporting via in-clinic paper-and pencil and mobile phone questionnaires. HVTN 915 was a prospective cohort study of 50 adult women in Soweto, who completed daily mobile phone, and eight interviewer-administered in-clinic questionnaires over 12 weeks to assess sexual risk. Daily mobile phone response rates were 82% (n = 3486/4500); 45% (n = 1565/3486) reported vaginal sex (median sex acts 2 (IQR: 1-3)) within 24 h and 40% (n = 618/1565) consistent condom. Vaginal sex reporting was significantly higher via mobile phone across all visits (p < 0.0001). There was no significant difference in condom use reporting by mobile phone and in-clinic paper-based questionnaires across all visits (p = 0.5134). The results show high adherence and reporting of sex on the mobile phone questionnaire. We demonstrate feasibility in collecting mobile phone sexual risk data. PMID- 29594619 TI - Colorimetric detection of genetically modified organisms based on exonuclease III assisted target recycling and hemin/G-quadruplex DNAzyme amplification. AB - An isothermal colorimetric method is described for amplified detection of the CaMV 35S promoter sequence in genetically modified organism (GMO). It is based on (a) target DNA-triggered unlabeled molecular beacon (UMB) termini binding, and (b) exonuclease III (Exo III)-assisted target recycling, and (c) hemin/G quadruplex (DNAzyme) based signal amplification. The specific binding of target to the G-quadruplex sequence-locked UMB triggers the digestion of Exo III. This, in turn, releases an active G-quadruplex segment and target DNA for successive hybridization and cleavage. The Exo III impellent recycling of targets produces numerous G-quadruplex sequences. These further associate with hemin to form DNAzymes and hence will catalyze H2O2-mediated oxidation of the chromogenic enzyme substrate ABTS2- causing the formation of a green colored product. This finding enables a sensitive colorimetric determination of GMO DNA (at an analytical wavelength of 420 nm) at concentrations as low as 0.23 nM. By taking advantage of isothermal incubation, this method does not require sophisticated equipment or complicated syntheses. Analyses can be performed within 90 min. The method also discriminates single base mismatches. In our perception, it has a wide scope in that it may be applied to the detection of many other GMOs. Graphical abstract An isothermal and sensitive colorimetric method is described for amplified detection of CaMV 35S promoter sequence in genetically modified organism (GMO). It is based on target DNA-triggered molecular beacon (UMB) termini-binding and exonuclease III assisted target recycling, and on hemin/G quadruplex (DNAzyme) signal amplification. PMID- 29594620 TI - A chromium(III) oxide-coated steel wire prepared by arc ion plating for use in solid-phase microextraction of aromatic hydrocarbons. AB - The authors introduce an arc ion plating method for the deposition of chromium oxide (Cr2O3) on a steel wire substrate, and its use as a coating for solid phase microextraction. The coating has a micro- and nano-scaled structure after annealing at 700 degrees C. It is found that Cr2O3 exhibits a good extraction capability for the aromatic hydrocarbons naphthalene, anthracene, fluorene, fluoranthene, and biphenyl. Following desorption by high temperature at 300 degrees C, the analytes were quantified by gas chromatography (GC). The limits of detection are in the range between 20 and 200 ng.L-1, and calibration plots are linear within a wide range (0.2 to 400 MUg.L-1). The coating has excellent mechanical properties, with a hardness is as high as 31.7 GPa, and the adhesion strength between coating and substrate reaches 20.1 N (corresponding to the critical Hertzian contact stress of 10 GPa). This, along with the chemical and thermal stability of the Cr2O3 coating, endows the wire with a long operational life. It was used for at least 100 times without any obvious decline of extraction capability. Graphical abstract An arc ion plating method was introduced for the deposition of chromium oxide (Cr2O3) on a steel wire substrate, and its use as a coating for solid phase microextraction with high mechanical strength, stability, and long operational lifetime. PMID- 29594621 TI - An amino-functionalized magnetic framework composite of type Fe3O4-NH2@MIL 101(Cr) for extraction of pyrethroids coupled with GC-ECD. AB - An amino-functionalized magnetic framework composite of type Fe3O4-NH2@MIL 101(Cr) was synthesized using a solvothermal method. The material was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, nitrogen adsorption, and magnetometry. The composite combines the advantages of amino-modified Fe3O4 and MIL-101(Cr). The presence of amino groups facilitates the fairly specific adsorption of pyrethroids. The composite was employed as a sorbent for magnetic solid phase extraction of five pyrethroids from environmental water samples. Following desorption with acidified acetone, the pyrethroids were quantified by gas chromatography with electron capture detection. The detection limits for bifenthrin, fenpropathrin, lambda-cyhalothrin, permethrin, and deltamethrin range from 5 to 9 pg.mL-1. The method is rapid, accurate, and highly sensitive. The molecular interactions and free binding energies between MIL-101(Cr) and the five pyrethroids were calculated by means of molecular docking. Graphical abstract A novel functionalized magnetic framework composite of type Fe3O4-NH2@MIL-101(Cr) was synthesized. It was applied as a sorbent for magnetic solid phase extraction of pyrethroids prior to their quantitation by gas chromatography with electron capture detection.

PMID- 29594622 TI - Intrinsic peroxidase-like activity of rhodium nanoparticles, and their application to the colorimetric determination of hydrogen peroxide and glucose. AB - The intrinsic peroxidase-like activity of rhodium nanoparticles (RhNPs) and their use as catalytic labels for sensitive colorimetric assays is presented. RhNPs catalyze the oxidation of the peroxidase substrate 3,3,5,5-tetramethylbenzidine (TMB) in the presence of H2O2 to produce a blue reaction product with a maximum absorbance at 652 nm. Kinetic studies show catalysis to follow Michaelis-Menten kinetics and a "ping-pong" mechanism. The calculated kinetic parameters indicate high affinity of RhNPs for both the substrate TMB and H2O2. In fact, they are better than other peroxidase mimicking nanomaterials and even the natural enzyme horseradish peroxidase. On the other hand, RhNPs exhibit no reactivity towards saccharides, thiols, amino acids and ascorbic acid. Based on these findings, a sensitive and selective colorimetric method was worked out for the determination of H2O2 in real samples with a linear response in the 1-100 MUM concentration range. By employing glucose oxidase, the glucose assay has a linear range that covers the 5 to 125 MUM glucose concentration range. The detection limits are <0.75 MUM for both species. The methods were applied to the determination of H2O2 in spiked pharmaceutical formulations, and of glucose in soft drinks and blood plasma. Figures of merit include (a) good accuracy (with errors of <6%), (b) high recoveries (96.5-103.7%), and (c) satisfactory reproducibility (<6.3%). Graphical abstract Rhodium nanoparticles catalyze the oxidation of 3,3,5,5 tetramethylbenzidine (TMB) in the presence of H2O2 to produce a blue reaction product. The effect is exploited in photometric assays for hydrogen peroxide and glucose. PMID- 29594624 TI - The influence of fatty acid supply and aldehyde reductase deletion on cyanobacteria alkane generating pathway in Escherichia coli. AB - Cyanobacteria alkane synthetic pathway has been heterologously constructed in many microbial hosts. It is by far the most studied and reliable alkane generating pathway. Aldehyde deformylating oxygenase (i.e., ADO, key enzyme in this pathway) obtained from different cyanobacteria species showed diverse catalytic abilities. This work indicated that single aldehyde reductase deletions were beneficial to Nostoc punctiforme ADO-depended alkane production in Escherichia coli even better than double deletions. Fatty acid metabolism regulator (FadR) overexpression and low temperature increased C18:1 fatty acid supply, and in turn stimulated C18:1-derived heptadecene production, suggesting that supplying ADO with preferred substrate was important to overall alkane yield improvement. Using combinational methods, 1 g/L alkane was obtained in fed-batch fermentation with heptadecene accounting for nearly 84% of total alkane. PMID- 29594623 TI - Colorimetric determination of ferrous ion via morphology transition of gold nanorods. AB - A colorimetric method is described for the determination of ferrous ion (Fe2+) with high sensitivity and selectivity. The method is based on catalytic etching of gold nanorod (NR). In an acid condition, Fe2+ reacts with H2O2 to produce superoxide radical (O2*-) that etches gold NRs from the low energy surface along the longitudinal direction preferentially. As a result, the changes in the absorption spectrum and color of gold NR can be measured and also can be detected visually. Under the optimal conditions, the assay has very low detection limit (13.5 nM) and a linear response in a concentration range of 75 to 1 MUM. The method was applied to the determination of Fe2+ in spiked samples of fetal bovine serum and also transferred to a kind of test stripe for use in fast practical applications. A unique colorimetric sensing method is demonstrated for the colorimetric detection of Fe2+, again based on the oxidation of gold nanorods which leads to the blue-shift of the absorption. Graphical abstract A unique colorimetric sensing method was shown for the colorimetric detection of Fe2+. Fe2+reacts with H2O2 to generate superoxide radical that oxidize gold nanorods. This leads to a color change from blue-green to pink. PMID- 29594625 TI - Colorimetric theophylline aggregation assay using an RNA aptamer and non crosslinking gold nanoparticles. AB - The authors are presenting a rapid method for the determination of theophylline using unique non-crosslinking gold nanoparticle (AuNP) aggregation. An RNA aptamer against theophylline is firstly split into two RNA fragments which then interact with bare AuNPs. The two RNA probes cause an enhancement of the salt tolerance of AuNPs. However, in the presence of theophylline, the RNA probes form a complex with theophylline so that less RNA probes are available to protect the AuNPs from salt-induced aggregation. Theophylline induced aggregation of AuNPs is accompanied by a color change from red to blue. The color change can be detected visually and via UV-vis absorptiometry by ratioing the absorbances at 650 and 520 nm. The ratio increases linearly in the 0.1 to 20 MUM theophylline concentration range, with a 67 nM limit of detection. The method is highly sensitive and selective. Graphical abstract Single-stranded split RNA aptamers (R1 and R2) protect gold nanoparticles (AuNPs) from salt-induced non-crosslinking aggregation. After recognition of theophylline by the RNA probe, the unprotected AuNPs aggregate and undergo a color change from red to blue, and this is used to quantify the theophylline concentration. PMID- 29594626 TI - A fluorescent DNA based probe for Hg(II) based on thymine-Hg(II)-thymine interaction and enrichment via magnetized graphene oxide. AB - The authors describe a fluorometric assay for the determination of Hg(II). A naphthalimide derivative is used as a label for a thymine (T) rich ssDNA, and graphene oxide magnetized with Fe3O4 nanoparticles acts as a quencher and preconcentrators. In the absence of Hg(II), the labeled ssDNA does not separate from the magnetized graphene oxide. As a result, fluorescence is fully quenched. In the presence of Hg(II), a T-Hg(II)-T link is formed dues to the highly affinity between T and Hg(II). Hence, fluorescence is restored. The assay has a linear response in the 1.0 to 10.0 nM Hg(II) concentration range, and a 0.65 nM detection limit. The method is selective and sensitive. It was applied to the analysis of spiked environmental water samples, and data agreed well with those obtained by atomic fluorescence spectrometry. Graphical abstract Strategy of a fluorescent probe for detecting Hg(II). The method has a 0.65 nM detection limit and is selective.

AB - Streams of the Pampasic plain in Southeastern South America are ecosystems affected by both water pollution and habitat alteration mainly due to agricultural activity. Water quality is influenced by the quality of habitats and both depend on land use and watershed morphology. The objective of this study was to determine the relationship between the variables of four factors: (1) the morphology of the watershed, (2) land use in the watershed, (3) river habitat, and (4) water quality of wadeable streams in Uruguay, as well as to determine the most representative variables to quantify such factors. We studied 28 watersheds grouped into three ecoregions and four principal activities, which generated seven zones with three to five streams each. Correlations between the variables of each factor allowed reducing the total number of variables from 57 to 32 to perform principal component analyses (PCA) by factor, reducing the number of variables to 18 for a general PCA. The first component was associated with water quality and elevation. The second was associated with the stream and watershed size, the third with habitat quality, and the fourth to the use of neighboring soils and objects in the channel. Our results indicate that agricultural intensity and elevation are the main factors associated with the habitat and water quality of these lowland streams. These factors must be especially considered in the development of water quality monitoring programs. PMID- 29594628 TI - An ultrasensitive conformation-dependent colorimetric probe for the detection of mercury(II) using exonuclease III-assisted target recycling and gold nanoparticles. AB - An ultrasensitive conformation-dependent colorimetric assay has been developed for the detection of mercury(II) ions. It is based on the use of exonuclease III (Exo III)-assisted target recycling and gold nanoparticles (AuNPs). In the absence of Hg(II), the hairpin-shaped DNA probe (H-DNA) binds to AuNPs and stabilizes them in solutions of high ionic strength. In the presence of Hg(II), on the other hand, the sticky termini of the H-DNA form a rigid DNA duplex stem with a blunt 3'-terminus. Thus, Exo III is activated as a biocatalyst for selective and stepwise removal of mononucleotides from the 3'-terminus of the H DNA. As a result, Hg(II) is released from the T-Hg(II)-T complexes. The guanine rich sequences released from the H-DNA are then self-assembled with potassium ion to form a stable G-quadruplex conformation. In solutions of high ionic strength, this results in aggregation of AuNPs and a color change from red to blue which can be seen with bare eyes. The method is highly sensitive and selective. It has a linear response in the 10 pM to 100 nM Hg(II) concentration range, and the detection limit is as low as 3.2 pM (at an S/N ratio of 3). The relative standard deviation at a level of 0.5 nM of Hg(II) is 4.9% (for n = 10). The method was applied to the detection of Hg(II) in spiked environment water samples, with recoveries ranging from 92% to 106%.

AB - This article describes a novel synthetic route to obtain hybrid nanostructures that combine the plasmonic properties of gold nanorods with the magnetic properties of iron oxide nanoparticles in a robust silica nanostructure. The silica matrix enhances the physico-chemical stability of the nanostructure and preserves its magneto-plasmonic properties by avoiding the interface between gold and iron oxide. In addition, the magneto-plasmonic features of the nanohybrids can be tuned due to the independent synthesis of each component. The magnetic and plasmonic properties of these nanostructures can potentially enhance the photoacoustic detection of circulating tumor cells. Graphical abstract Schematic presentation of a hybrid magneto-plasmonic nanoparticle with an Au@Fe3O4@SiO2 core-satellite-shell arrangement. The magnetic and plasmonic responses of this kind of nanostructure enable magnetic trapping and photoacoustic detection of circulating tumor cells.

AB - An ultrasensitive immunosensor for the direct detection of the illegally used livestock feed clebuterol (CLB) is described. It is based on the use of a glassy carbon electrode modified with an MoS2-AuPt nanocomposite and on biotin streptavidin interaction. The use of MoS2-AuPt accelerates electron transfer, and this leads to a sharp increase in the electrochemical signal for the electrochemical probe hydrogen peroxide. Differential pulse voltammetry was used to record the current signal at a peak potential of -0.18 V (vs SCE). Under optimal conditions, the electrode has a linear response in the 10 pg.mL-1 to 100 ng.mL-1 CLB concentration range and a 6.9 pg.mL-1 detection limit (based on the 3sigma criterium). This immunosensor is sensitive, highly specific and acceptably reproducible, and thus represents a valuable tool for the determination of CLB in pork. Graphical abstract Schematic of a voltammetric immunosensor for the determination of clenbuterol (CLB) based on the use of a nanocomposite prepared from molybdenum disulfide and a gold-platinum alloy (MoS2-AuPt), and making use of the biotin-streptavidin system. PMID- 29594631 TI - Microfluidic electrophoretic non-enzymatic kanamycin assay making use of a stirring bar functionalized with gold-labeled aptamer, of a fluorescent DNA probe, and of signal amplification via hybridization chain reaction. AB - The authors describe an enzyme-free aptamer-based assay for the determination of the model antibiotic kanamycin (Kana). The method is making use of (a) microfluidic chip electrophoresis; (b) a stirring bar carrying a gold-labeled aptamer probe, and (c) the hybridization chain reaction (HCR) for signal amplification. Firstly, a stirring bar (length: 1 cm; diameter: 0.2 mm) was modified with a large amount of duplex DNA and then hybridized with aptamer and its partially complementary chains (cDNA). In the presence of Kana, the binding between the Kana and aptamer unwinds the duplex structures and releases a corresponding amount of cDNA into the supernatant. The released cDNA triggers the HCR in the presence of H1 and H2 DNA hairpin to produce a large amount of duplex DNA chains with different lengths. At the same time, the amounts of H1 and H2 are reduced. The decreased signal of H1/H2 after several HCR cycles can be used to quantify kana in the 1 pg.mL-1 to 10 ng.mL-1, with a detection limit of 0.29 pg.mL-1. The signal is generated by reading the fluorescence, best at excitation/emission maxima of 470/525 nm. The whole detection process takes 3 min only. The assay was employed to the detection of Kana in spiked milk and fish samples. Results are consistent with those of an enzyme linked immunosorbent assay. The assay has high throughput, high selectivity, and high amplification capability. Graphical abstract Schematic of a stirring bar functionalized with gold-labeled aptamer acting as the capture probe. It can capture the target and release primer simultaneously. The primer triggers the hybridization chain reaction inducing the consumption of H1 and H2. After a certain reaction time, the mixture is injected into the MCE platform for microfluidic electrophoretic separation and fluorometric detection.

AB - The authors describe a highly sensitive method for the aptamer (Apt) based impedimetric determination of cocaine. The surface of a screen-printed electrode (SPE) was modified with a nanocomposite of dendrimer and silver nanoparticles (AgNPs). The cocaine-binding Apt was attached to a dendrimer/AgNP/SPE surface, forming a sensitive layer for the determination of cocaine. The incubation with the analyte resulted in the formation of a cocaine/Apt complex on the electrode surface. As a consequence, folding and conformational change in the aptamer structure was induced, this resulting in a change in the impedimetric signal. The aptaassay exhibits highly efficient sensing characteristics with a good linearity of 1 fmol L-1 to 100 nmol L-1 (with two linear ranges) and a limit of detection (LOD) of 333 amol L-1. Its excellent specificity and high sensitivity suggest that this kind of aptamer-based assay may be applied to detect other targets in this field.

AB - The authors describe a sandwich-type of electrochemical immunoassay for rapid determination of the foodborne pathogen Cronobacter sakazakii (C. sakazakii). Polyclonal antibody against C. sakazakii (anti-C. sakazakii) and horseradish peroxidase were immobilized on a nanocomposite consisting of reduced graphene oxide, thionine and gold nanoparticles (AuNPs) that was placed on a screen printed carbon electrode (SPCE). Thionine acts as an electron mediator which also shortens the electron transfer pathway from the conjugated HRP to the electrode surface and amplifies the electrochemical signal. The AuNPs, in turn, improve the electron transfer rate and increase the surface area for capturing antibody. The morphologies of the electrodes were characterized by means of field emission scanning electron microscopy. The electrochemical performance of the immunoassay was evaluated by cyclic voltammetry and differential pulse voltammetry. Under optimal experimental conditions, the electrochemical immunoassay, best operated at a woking potential of -0.18 V (vs. Ag/AgCl) and scan rate of 20 mV/s has a linear response that covers the 8.8 * 104 to 8.8 * 108 CFU.mL-1 C. sakazakii concentration range, with a 1.0 * 104 CFU.mL-1 detection limit (at an S/N ratio of 3). The assay was applied to the detemination of C. sakazakii in spiked infant milk powder and gave recoveries ranging from 92.0 to 105.7%. Graphical abstract A sandwich-type electrochemical immunosensor was designed for C. sakazakii based on the use of rGO. TH, HRP, antibody and AuNPs were anchored on rGO. The nanocomposites were used as traces tag and H2O2 as enzyme substrates. AuNPs were modified on SPCE by electrodeposition. PMID- 29594634 TI - An "off-on" colorimetric and fluorometric assay for Cu(II) based on the use of NaYF4:Yb(III),Er(III) upconversion nanoparticles functionalized with branched polyethylenimine. AB - The authors describe an "off-on" colorimetric and fluorometric assay for the determination of Cu(II). It is based on the use of upconversion nanoparticles (UCNPs) of type NaYF4:Yb(III),Er(III) that were functionalized with branched polyethylenimine (BPEI). A color change from colorless to blue occurs within 2 s after addition of Cu(II) to a solution of the modified UCNPs. The color change can be visually detected at Cu(II) concentrations down to 80 MUM. The upconversion fluorescence of the modified UCNPs, measured at excitation wavelength of 980 nm, is reduced due to the predominant inner filter effect caused by the formation of the BPEI-Cu(II) complex. Normalized fluorescence intensity drops linearly in the 50 nM to 10 MUM Cu(II) concentration range, and the fluorometric detection limit is 45 nM. Both the color and the fluorescence are recovered on addition of EDTA. Excellent selectivity over other metal ions and anions is achieved. Graphical abstract Upconversion nanoparticles of type NaYF4:Yb,Er were functionalized with branched polyethylenimine (UCNP/BPEI) and used in an "off-on" colorimetric and fluorometric assay for Cu(II). The upconversion fluorescence is selectively quenched on addition of Cu(II), and this is accompanied by a rapid colorless-to-blue color switch. The colorimetric changes and quenched fluorescence can be reversed by adding EDTA. PMID- 29594635 TI - Reading, Trauma and Literary Caregiving 1914-1918: Helen Mary Gaskell and the War Library. AB - This article is about the relationship between reading, trauma and responsive literary caregiving in Britain during the First World War. Its analysis of two little-known documents describing the history of the War Library, begun by Helen Mary Gaskell in 1914, exposes a gap in the scholarship of war-time reading; generates a new narrative of "how," "when," and "why" books went to war; and foregrounds gender in its analysis of the historiography. The Library of Congress's T. W. Koch discovered Gaskell's ground-breaking work in 1917 and reported its successes to the American Library Association. The British Times also covered Gaskell's library, yet researchers working on reading during the war have routinely neglected her distinct model and method, skewing the research base on war-time reading and its association with trauma and caregiving. In the article's second half, a literary case study of a popular war novel demonstrates the extent of the "bitter cry for books." The success of Gaskell's intervention is examined alongside H. G. Wells's representation of textual healing. Reading is shown to offer sick, traumatized and recovering combatants emotional and psychological caregiving in ways that she could not always have predicted and that are not visible in the literary/historical record. PMID- 29594636 TI - Silver-doped CdS quantum dots incorporated into chitosan-coated cellulose as a colorimetric paper test stripe for mercury. AB - Silver-doped CdS quantum dots capped with mercaptoacetic acid were incorporated into a chitosan-coated filter paper to fabricate a colorimetric test stripe for mercury. Chitosan assisted in the stabilization of CdSAg QDs on cellulose and enhanced the analyte diffusion in the test stripe. Hg(II) ions were captured by mercaptoacetic acid on CdSAg, resulting in a visualized color change from yellow to deep brown. For enhanced sensitivity and quantitation with good reproducibility, the color intensity was recorded, transmitted to a smartphone camera and computed by the ImageJ software to provide a digital readout. The assay was rapid, simple, and selective for mercury as several potential interfering species provoked no signal response. The applicability of the sensing approach was demonstrated for the analysis of spiked Hg(II) ions in cosmetic cream with a detection limit of 124 MUM. Graphical abstract Schematic of a colorimetric test stripe consisting of silver-doped CdS quantum dots coated withmercaptoacetic acid and embedded into a chitosan matrix on paper. It enables mercury(II) to be visuallyquantified even in complex matrices such as cosmetics.

AB - Excitation-emission matrix fluorescence (EEMF) and total synchronous fluorescence spectroscopy (TSFS) are the 2 fluorescence techniques that are commonly used for the analysis of multifluorophoric mixtures. These 2 fluorescence techniques are conceptually different and provide certain advantages over each other. The manual analysis of such highly correlated large volume of EEMF and TSFS towards developing a calibration model is difficult. Partial least square (PLS) analysis can analyze the large volume of EEMF and TSFS data sets by finding important factors that maximize the correlation between the spectral and concentration information for each fluorophore. However, often the application of PLS analysis on entire data sets does not provide a robust calibration model and requires application of suitable pre-processing step. The present work evaluates the application of genetic algorithm (GA) analysis prior to PLS analysis on EEMF and TSFS data sets towards improving the precision and accuracy of the calibration model. The GA algorithm essentially combines the advantages provided by stochastic methods with those provided by deterministic approaches and can find the set of EEMF and TSFS variables that perfectly correlate well with the concentration of each of the fluorophores present in the multifluorophoric mixtures. The utility of the GA assisted PLS analysis is successfully validated using (i) EEMF data sets acquired for dilute aqueous mixture of four biomolecules and (ii) TSFS data sets acquired for dilute aqueous mixtures of four carcinogenic polycyclic aromatic hydrocarbons (PAHs) mixtures. In the present work, it is shown that by using the GA it is possible to significantly improve the accuracy and precision of the PLS calibration model developed for both EEMF and TSFS data set. Hence, GA must be considered as a useful pre-processing technique while developing an EEMF and TSFS calibration model. PMID- 29594638 TI - A SERS method with attomolar sensitivity: a case study with the flavonoid catechin. AB - Making good use of interactions between analyte molecules and the metal nanoparticles is key to impact the detection limit in a surface-enhanced Raman scattering (SERS) based detections. SERS was applied to the analysis of catechin and it was found that the relative abundance of catechin in the sample to citrate capped AgNPs and the aggregation agent NaCl plays a critical role in the quality of detection. At a component volume ratio of 6:2:1 (catechin:AgNPs:NaCl), catechin can be detected at uM levels. When the ratio is 12:2:1, Raman signals are discernible even at the attomolar concentration level (10-18 M). Under these conditions, the SERS mechanisms and the force of laser tweezers function best. The extent of signal enhancement enabled an ultrasensitive and reproducible Raman spectroscopic determination of catechin. Graphical abstract At a component volume ratio of 6:2:1 (catechin:AgNPs:NaCl), catechin was detected at 10-3 M to 10-6 M. When the ratio was 12:2:1, the discernible concentration of catechin was found to reach the attomolar level (10-18 M). PMID- 29594639 TI - Determination of nickel(II) at nanomolar levels using iodide-responsive gold copper nanoparticles as colorimetric probes. AB - The authors present a colorimetric method for the quantification of Ni(II) at nanomolar levels. It is based on the use of iodide-responsive copper-gold nanoparticles (Cu-Au NPs) combined with the Ni(II)-catalyzed glutathione (GSH) oxygen reaction system. In the presence of Ni(II), the catalytic reaction between GSH and oxygen is can triggered. This leads to the formation of GSSG which is bulky and hinders the access of iodide to the surface of the Cu-Au NPs. Concomitantly, the color of the solution containing the Cu-Au NPs changes from gray to red. Based on these findings, a method was developed for the quantitation of Ni(II) that has a detection limit as low as 0.54 nM. This is 1-3 orders of magnitude lower than that of previously reported optical methods. The assay has excellent selectivity for Ni(II), is rapid, cost-effective, portable, and allows for bare eye observation. Conceivably the method is suitable for field detection of Ni(II) in biological, food, and environmental samples. Graphical Abstract A sensitive colorimetric strategy for Ni(II) through the combination of iodide responsive Cu-Au NPs with Ni(II)-catalyzed the oxidation of GSH by oxygen was presented. PMID- 29594640 TI - Gold nanoparticles functionalized with Pluronic are viable optical probes for the determination of uric acid. AB - The authors describe the preparation of gold nanoparticles (AuNPs) coated with poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (Pluronic F-108) by reducing Au3+ to Au0 using curcumin, a natural and non-toxic food spice, in water of pH ~7 in the presence of F-108 and Ag+ ion. The coated AuNPs display strong resonance Rayleigh scattering (RRS) and fluorescence that results from the functionalization of the gold surface with curcumin and Pluronic F-108. The molar mass of Pluronic F-108 affects the particle size of the AuNPs formed, and small AuNPs are formed when using low molar weight F-108 that was purified by centrifugation or dialysis. The coated AuNPs were employed in an optical method for the determination of uric acid. The combination of uric acid with the AuNPs boosts both the RRS signal and the fluorescence of the AuNPs. However, higher concentrations of uric acid shift the fluorescence peak to shorter wavelengths. The method is simple, and fluorescence, best measured at excitation/emission wavelengths of 425/534 nm, increases linearly in the 50 MUM to 50 mM uric acid concentration range, with a 0.14 MUM detection limit which is lower than reported for other methods in the literature. Graphical abstract Pluronic F-108 capped gold nanoparticles prepared by reducing Au3+ to Au0 using curcumin can estimate uric acid in 50 MUM to 50 mM concentration range.

Yet, few studies have investigated provincial differences related to life interference due to gambling. The objectives of the current study were to examine: (1) provincial differences with regard to gambling types and (2) if gender, family history of gambling, and alcohol or drug use while gambling were related to an increased likelihood of life interference in three Canadian provinces. Data were drawn from the 2013 and 2014 cycles of the Canadian Community Health Survey from Manitoba, Saskatchewan, and British Columbia (n = 30,150). Analyses were conducted stratified by provinces and also combined using logistic regression models. Provincial differences were noted with individuals from British Columbia compared to Manitoba being less likely to play VLTs outside of casinos, play live horse racing at a track or off track, and participate in sports gambling. Those in Saskatchewan compared to Manitoba were more likely to play VLTs inside a casino. When examining all provinces combined, family history of gambling was associated with increased odds of life interference. Gender was not associated with life interference. Provincial differences were noted, which may be in part related to differences in gambling landscapes. Family history of gambling may have clinical relevance for understanding which individuals may be more likely to experience life interference due to gambling. Further research is needed to clarify the link between alcohol and drug use while gambling and life interference due to gambling as the models in the current research were likely underpowered.

AB - A nanocomposite consisting of a few layers of graphene (FLG) and tin dioxide (SnO2) was prepared by ultrasound-assisted synthesis. The uniform SnO2 nanoparticles (NPs) on the FLG were characterized by X-ray diffraction in terms of lattice and phase structure. The functional groups present in the composite were analyzed by FTIR. Electron microscopy (HR-TEM and FE-SEM) was used to study the morphology. The effect of the fraction of FLG present in the nanocomposite was investigated. Sensitivity, selectivity and reproducibility towards resistive sensing of liquid propane gas (LPG) was characterized by the I-V method. The sensor with 1% of FLG on SnO2 operated at a typical voltage of 1 V performs best in giving a rapid and sensitive response even at 27 degrees C. This proves that the operating temperature of such sensors can be drastically decreased which is in contrast to conventional metal oxide LPG sensors. Graphical abstract Schematic of a room temperature gas sensor for liquefied petroleum gas (LPG). It is based on the use of a few-layered graphene (1 wt%)/SnO2 nanocomposite that was deposited on an interdigitated electrode (IDEs). A sensing mechanism for LPG detection has been established. PMID- 29594643 TI - Ultrasensitive amperometric aptasensor for the epithelial cell adhesion molecule by using target-driven toehold-mediated DNA recycling amplification. AB - An amperometric aptasensor is reported for the electrochemical determination of the epithelial cell adhesion molecule (EpCAM). It is based on a combination of EpCAM-driven toehold-mediated DNA recycling amplification, the specific recognition of EpCAM aptamer, and its binding to EpCAM. Hairpin probe 1 (Hp1) with a toehold region was modified with a 5'-thiol group (5'-SH) and self assembled onto the surface of a gold electrode. Upon addition of EpCAM, the probe A (a 15-mer) is liberated from the aptamer/probe A complex and then hybridizes with the toehold domain of Hp1. This results in the exposure of another toehold for further hybridizing with hairpin probe 2 (Hp2) to displace probe A in the presence of Hp2 that was labeled with the electrochemical probe Methylene Blue (MB). Subsequently, liberated probe A is hybridized again with another Hp1 to start the next round of DNA recycling amplification by reusing probe A. This leads to the formation of plenty of MB-labeled DNA strands on the electrode surface and generates an amplified current. This 1:N probe-response amplification results in ultrasensitive and specific detection of EpCAM, with a 20 pg.mL-1 detection limit. The electrode is highly stable and regenerable. It was successfully applied to the determination of EpCAM in spiked human serum, urine and saliva, and thus provides a promising tool for early clinical diagnosis. Graphical abstract Schematic illustration of the electrochemical detection for EpCAM. The method is based on aptamer-based recognition and EpCAM-driven toehold mediated DNA recycling amplification.

PMID- 29594644 TI - Non-osteogenic muscle hypertrophy in children with McArdle disease. AB - INTRODUCTION: McArdle disease is an inborn disorder of muscle glycogen metabolism that produces exercise intolerance, and has been recently associated with low values of lean mass (LM) and bone mineral content (BMC) and density (BMD) in affected adults. Here we aimed to study whether this bone health problem begins in childhood. METHODS: Forty children and adolescents were evaluated: 10 McArdle disease and 30 control children (mean age of both groups, 13 +/- 2y). Body composition was evaluated by dual-energy X-ray absorptiometry and creatine kinase (CK) levels were determined in the patients as an estimate of muscle damage. RESULTS: Legs bone mass was significantly lower in patients than in controls ( 36% for BMC and -22% for BMD). Moreover, patients had significantly higher LM values in the legs than controls, whereas no difference was found for fat mass. CK levels were positively associated with LM in McArdle patients. A correlation was found between LM and BMD variables in the control group but not in McArdle patients. CONCLUSION: We have identified a 'non-osteogenic muscle hypertrophy' in children with McArdle disease. This phenomenon warrants special attention since low osteogenesis at an early age predicts a high risk for osteoporosis later in life. PMID- 29594646 TI - Newborn screening for Pompe disease: impact on families. AB - Pompe disease (PD) is an autosomal recessive lysosomal storage disorder causing progressive glycogen accumulation in muscles, with variability in age of onset and severity. For infantile-onset PD (IOPD), initiation of early treatment can be life-saving; however, current newborn screening (NBS) technology cannot distinguish IOPD from late-onset PD (LOPD) without clinical workup. Therefore, families of LOPD infants diagnosed by NBS may now spend years or even decades aware of their illness before symptoms appear, creating a pre-symptomatic awareness phase with which the medical community has little experience. The present study examines the effects of receiving a positive NBS result for PD on families. In-depth qualitative interviews were conducted with mothers of nine children (three IOPD and six LOPD) diagnosed via NBS, exploring their experiences, understanding of PD, how they are coping, and what impact diagnosis is having on family life. Interviews were coded using MaxQDA v.12 and analyzed for thematic trends. While overall opinion of NBS was favorable, it is clear many of the concerns anticipated by HCPs, patients, and families regarding NBS for late-onset LSDs are being realized to varying degrees; LOPD families are becoming patients-in-waiting. Increased fear/anxiety and living with uncertainty (regarding diagnosis, their children's future, and when to start treatment) were predominant themes, with all families voicing considerable emotional reactions and varied social and healthcare support concerns. Coping strategies and psychosocial challenges are interpreted using Rolland & Williams' Family Systems Genetic Illness model. Recommendations for improvement in delivery of service, as well as families' advice for future parents and HCPs, are discussed. PMID- 29594645 TI - The role of suboptimal mitochondrial function in vulnerability to post-traumatic stress disorder. AB - Post-traumatic stress disorder remains the most significant psychiatric condition associated with exposure to a traumatic event, though rates of traumatic event exposure far outstrip incidence of PTSD. Mitochondrial dysfunction and suboptimal mitochondrial function have been increasingly implicated in several psychopathologies, and recent genetic studies have similarly suggested a pathogenic role of mitochondria in PTSD. Mitochondria play a central role in several physiologic processes underlying PTSD symptomatology, including abnormal fear learning, brain network activation, synaptic plasticity, steroidogenesis, and inflammation. Here we outline several potential mechanisms by which inherited (genetic) or acquired (environmental) mitochondrial dysfunction or suboptimal mitochondrial function, may contribute to PTSD symptomatology and increase susceptibility to PTSD. The proposed pathogenic role of mitochondria in the pathophysiology of PTSD has important implications for prevention and therapy, as antidepressants commonly prescribed for patients with PTSD have been shown to inhibit mitochondrial function, while alternative therapies shown to improve mitochondrial function may prove more efficacious. PMID- 29594647 TI - Pregnancy management and outcome in patients with four different tetrahydrobiopterin disorders. AB - INTRODUCTION: Inborn errors of tetrahydrobiopterin (BH4) biosynthesis or recycling are a group of very rare neurometabolic diseases. Following growing awareness and improved availability of drug treatment the number of patients with BH4 disorders reaching adulthood is constantly increasing. Pregnancy care of patients with these disorders is therefore a new challenge for clinicians. METHODS: This retrospective study summarises for the first time clinical and biochemical monitoring data of 16 pregnancies in seven women with different disorders of BH4 metabolism and evaluates treatment regimens before and during pregnancy in relation to the obstetrical outcome and paediatric follow-up. RESULTS: Worsening of pre-existing neurological symptoms or occurrence of new symptoms during pregnancy was not observed in most of the cases. Treatment regimens remained mostly unchanged. Pregnancies were not complicated by disease specific features. Organ abnormalities, miscarriage, prematurity, IUGR and chromosomal changes were occasionally reported, without showing any association with the standard drug treatment for BH4 deficiencies. CONCLUSION: Although our data on 16 pregnancies in seven patients did not present any association of standard drug treatment with an increased rate of pregnancy complications, abnormal obstetrical or paediatric outcome, an intensive clinical and biochemical supervision by a multidisciplinary team before, during and after the pregnancy in any BH4 deficiency is essential since available data on pregnancies in patients with BH4 deficiencies is limited. PMID- 29594648 TI - Identification and characterization of 40 novel hydroxymethylbilane synthase mutations that cause acute intermittent porphyria. AB - Acute intermittent porphyria (AIP), an autosomal dominant disorder due to the half-normal activity of hydroxymethylbilane synthase (HMBS), is characterized by acute neurovisceral attacks that are precipitated by factors that induce heme biosynthesis. Molecular diagnosis is the most sensitive and specific diagnostic test for AIP, and importantly, it permits the identification of asymptomatic family members for genetic counseling and avoidance of precipitating factors. Here, we report the identification of 40 novel HMBS mutations, including 11 missense, four nonsense, 16 small insertions or deletions, eight consensus splice site mutations, and a complex insertion-deletion mutation in unrelated individuals with AIP. Prokaryotic expression of the missense mutations demonstrated that all mutants had <=5% of expressed wildtype activity, except for c.1039G>C (p.A347P), which had 51% residual HMBS activity but was markedly thermolabile. Of note, the mutation c.612G>T (p.Q204H) altered the last nucleotide of exon 10, which resulted in an alternative HMBS transcript with an in-frame nine base-pair deletion at the 3'-terminus of exon 10 (encoding protein Q204HDelta3). When expressed, Q204HDelta3 and an in-frame three base-pair deletion (c.639_641delTGC) had no detectable HMBS activity. Western blot analyses and mapping of the missense mutations on the human HMBS crystal structure revealed that mutations near the active site or at the dimerization interface resulted in stably expressed proteins, while most that altered surface residues resulted in unstable proteins, presumably due to improper protein folding. These studies identified novel pathogenic HMBS mutations and expanded the molecular heterogeneity of AIP. PMID- 29594649 TI - Gold nanoclusters as a quenchable fluorescent probe for sensing oxygen at high temperatures. AB - Gold nanoclusters (AuNCs) capped with lipoic acid (LA) or templated with bovine serum albumin (BSA) are shown to be viable fluorescent probes for oxygen (O2) which acts as a collisional quencher. Quenching of fluorescence, with its lifetimes in the order of 123 +/- 9 ns (LA) and 153 +/- 15 ns (BSA) (in aqueous solution), is best measured at excitation/emission wavelengths of 400/680 nm and 375/650 nm respectively. It follows the Stern-Volmer model, whose quenching constants (Ksv) and quenching efficiencies (gamma) are 1400 M-1 and 0.52 for AuNC@LA and 4479 M-1 and 0.90 for AuNC@BSA. The probes were immobilized on a silica support and tested for response to O2 in gas phase using a commercial instrument. The effect of temperature on the fluorescence of AuNC@LA was studied in the range from 30 to 210 degrees C. Fluorescence intensity slightly decreases with temperature in the first heating cycle but remains constant in further cycles. The AuNC@LA were studied for their response to O2 in the temperature range from 30 to 100 degrees C, and even at 100 degrees C they respond to O2, with a Ksv that slightly drops with increasing temperature. Measuring in gas phase at 100 degrees C, the sensor has a detection limit of 3% (V/V) of O2 at a signal-to-noise ratio of 3. Graphical Abstract Gold-nanoclusters (AuNCs) fluorescence intensity (lambdaexc = 400 nm, lambdaem = 680 nm) remains constant from 30 to 210 degrees C and is quenched by O2 following a collisional mechanism. The Stern-Volmer constant (Ksv) slightly changes from 25 degrees C to 100 degrees C (at least).

AB - A nanohybrid mediated SERS substrate was prepared by in-situ synthesis and assembly of gold nanoparticles (AuNPs) on exfoliated nanosheets of tungsten disulfide (WS2) to form plasmonic hotspots. The nanohybrid surface was functionalized with specific aptamers which imparted high selectivity for the cardiac marker myoglobin (Mb). The fabricated aptasensor was read by SERS using a 532 nm laser and demonstrated significant signal enhancement, and this allowed Mb to be determined in the 10 f. mL-1 to 0.1 MUg mL-1 concentration range. The study presents an approach to synergistically exploit the unique chemical and electromagnetic properties of both WS2 and AuNPs for many-fold enhancement of SERS signals. Graphical abstract Schematic presentation of a nanohybrid-mediated SERS substrate prepared by in-situ assembly of gold nanoparticles (AuNPs) reduced on exfoliated nanosheets of tungsten disulfide (WS2) to form plasmonic hot spots. Specific aptamers immobilized on the SERS surface impart high sensitivity and selectivity for the cardiac marker myoglobin (Mb).

We evaluated three hypotheses: (1) reading the Bible moderates the relationship between stress and hope; (2) people who read the Bible more often are more likely to rely on benevolent religious reappraisal coping responses; and (3) individuals who rely on benevolent religious reappraisals will be more hopeful about the future. Support was found for all three hypotheses in our analyses. PMID- 29594652 TI - The Relationship Between Religious and Psychospiritual Measures and an Inflammation Marker (CRP) in Older Adults Experiencing Life Event Stress. AB - Inflammation, often measured by C-reactive protein (CRP), is thought to be related to a number of debilitating illnesses as we age, including cardiovascular disease, cancer and diabetes. Stress has also been implicated in these processes. This study examines potential protective effects of spirituality and religion in older adults who have experienced stressful life events. As part of the nationwide Landmark Study of Spirituality and Health, a subsample of 643 middle aged and older adults (age >= 50) who were at or above the median in number of life stressors (>= 2) was included in this analysis. Psychospiritual and religious (PS/R) variables included: religious service attendance, prayer, religious meaning, religious hope, general meaning, general hope and sense of peace. Control variables included: age, gender, education, BMI, smoking, alcohol use, social support. Only church attendance predicted significantly lower CRP after controlling for covariates, even above the other PS/R variables (standardized beta = - 0.14, t = - 3.23 p = 0.001). Those with frequent religious service attendance were 38% less likely to have clinically elevated CRP than those who attend rarely or never. Religious service attendance may confer protection in older adults experiencing stressful events as it was significantly associated with lower CRP, an inflammatory marker associated with illness.

AB - The authors describe a method for the determination of carbonyl pollutants adsorbed on ambient particulate matter (diameter < 2.5 MUm; PM2.5). 2,4 Dinitrophenylhydrazine (DNPH) was used to derivatize carbonyl compounds. Magnetic molecularly imprinted polymers (MMIPs) selective for 2,4-DNPH were synthesized to remove excess of the derivatization reagent 2,4-DNPH. Micellar electrokinetic chromatography (MEKC) was then applied to the separation of DNPH-derivatized carbonyl compounds. The increased sensitivity of MEKC with UV detection and the sample cleanup resulted in drastically reduced sampling times (15 min) with detection limits ranging from 0.005-0.068 MUg.m-3 for different carbonyls. The method was applied to continuous monitoring of carbonyl compounds on ambient PM 2.5 for two consecutive months. The concentrations and gas-to-particle ratios of carbonyls were determined, and a statistical method was used to evaluate the correlation among different carbonyls. It was observed that the total concentration of carbonyls, especially of multi-carbon carbonyls, increases with the level of air pollution. The level of isovaleraldehyde rises sharply and accounts for 37% of total carbonyls on days with extremely humid haze. The ratio of acetaldehyde to propionaldehyde (C2/C3) decreases with the duration and heaviness of haze conditions. Results indicate that anthropogenic emissions and the characteristics of the atmosphere (e.g. temperature, sunlight, and relative humidity) are the main factors that lead to abnormally high levels of isovaleraldehyde and other carbonyls in ambient PM 2.5. Graphical abstract Schematic of a method for the determination of carbonyl pollutants adsorbed on ambient fine particle of type PM2.5. Magnetic molecularly imprinted polymers (MMIPs) were synthesized to remove the excess derivatization reagent (2,4-DNPH) in air sample prior to CE separation. PMID- 29594654 TI - Aptamer-based determination of tumor necrosis factor alpha using a screen-printed graphite electrode modified with gold hexacyanoferrate. AB - An aptamer based method is presented for the voltammetric determination of human tumor necrosis factor alpha (TNF-alpha). Layers of gold hexacyanoferrate (AuHCF) and gold nanoparticles (AuNPs) were directly immobilized on a graphite screen printed electrode (SPE). Through the strong interaction between cyanide ions (CN ) of AuHCF and AuNPs, gold nanoparticles are assembled on the modified SPE, and this allows for the covalent immobilization of thiolated aptamers against TNF alpha (TNF-alpha-Apt). On incubation of the aptasensor with of TNF-alpha, the Apt/TNF-alpha complex is formed, and this leads to a hindered electron transfer and to a decrease in the peak current of the redox probe. Under optimum conditions and at a typical working as low as 0.1 V (vs. a silver pseudo electrode), the electrode works in the 10 pg.mL-1 to 40 MUg.mL-1 TNF-alpha concentration range, with a 5.5 pg.mL-1 detection limit. The high sensitivity and wide detection range of this method allowed TNF-alpha to in human serum be detected even at very low concentrations.

AB - The authors describe a fluorescent "turn-on" assay for detection of uric acid (UA) based on the use of graphene quantum dots coated with a shell of silver (GQD@Ag). The fluorescence of the GQDs is quenched by the silver shell. However, if the silver shell was removed via etching with H2O2 (which is produced by uricase catalyzed oxidation of UA), the fluorescence of the GQDs is restored. The resulting increase in fluorescence at 466 nm depends directly on the concentration of H2O2, which, in turn, depends on the concentration of UA. The method allows UA to be quantitated with a 2 MUM detection limit. It was applied to the analysis of human urine samples and exhibited satisfactory results. The method is cost-effective, sensitive and selective for UA. In our perception, it provides a useful tool in clinical analysis and may be extended to other assays based on the use of oxidases. Graphical abstract Schematic of the reduction of Ag(I) and the growth of a silver shell on the surface of graphene quantum dots (GQDs) to form a GQD@Ag nanocomposite whose fluorescence is quenched. Uricase catalyzes the oxidation of uric acid (UA) to produce allantoin and H2O2 which etches the silver shell. This results in the release of GQDs and increased fluorescence, allowing quantitative analysis of UA.

AB - PURPOSE: The objective was to investigate (with quantitative MRI) whether the normal appearing white matter (NAWM) of glioblastoma (GBM) patients on the contralateral side (cNAWM) was different from NAWM of healthy controls. METHODS: Thirteen patients with newly diagnosed GBM and nine healthy age-matched controls were MRI-scanned with quantitative magnetization transfer (qMT), chemical exchange saturation transfer (CEST), and transverse relaxation time (T2)-mapping. MRI scans were performed after surgery and before chemo-radiation treatment. Comprehensive qMT, CEST, T2 data were acquired. A two-pool MT model was fit to qMT data in transient state, to calculate MT model parameters [Formula: see text]. CEST signal was isolated by removing the contributions from the MT and direct water saturation, and CEST signal was calculated for Amide (CESTAmide), Amine (CESTAmine) and nuclear overhauser effect, NOE (CESTNOE). RESULTS: There was no difference between GBM patients and normal controls in the qMT properties of the macromolecular pool [Formula: see text]. However, their free water pool spectrum was different (1/RaT2a,patient = 28.1 +/- 3.9, 1/RaT2a,control = 25.0 +/ 1.1, p = 0.03). This difference could be attributed to the difference in their T2 time ([Formula: see text] = 83 +/- 4, [Formula: see text] = 88 +/- 1, p = 0.004). CEST signals were statistically significantly different with the CESTAmide having the largest difference between the two cohorts (CESTAmide,patient = 2.8 +/- 0.4, CESTAmide,control = 3.4 +/- 0.5, p = 0.009). CONCLUSIONS: CEST in cNAWM of GBM patients was lower than healthy controls which could be caused by modified brain metabolism due to tumor cell infiltration. There was no difference in MT properties of the patients and controls, however, the differences in free water pool properties were mainly due to reduced T2 in cNAWM of the patients (resulting from structural changes and increased cellularity). PMID- 29594657 TI - A predictive value of von Willebrand factor for early response to Bevacizumab therapy in recurrent glioma. AB - Bevacizumab (BV), a neutralizing monoclonal antibody against the vascular endothelial growth factor ligand, is recognized as a potent anti-angiogenic agent with antitumor activity. The aim of this single-center, retrospective, longitudinal study was to investigate the possible predictive value of baseline demographic, clinical and laboratory parameters for early 3-month response to BV therapy in patients with recurrent glioma. Forty-nine patients with recurrent glioma received BV at 10 mg/kg intravenously every 3 weeks alone or in association with chemotherapy were included in this study. Blood samples were collected from all patients before the first (baseline), the second and the third administration of BV. After 3 months of BV therapy, patients with partial response were defined as responders whereas patients with stable or progressive disease were defined as non-responders. The median overall follow-up was 8 months (range 1-73), the median overall survival (OS) was 8 months (95% CI 6-10) and the median progression free survival (PFS) was 4 months (95% CI 3-5). Thirty-five % of patients were responders and showed significantly lower von Willebrand factor (VWF) levels than non-responders at all sample times (p < .02 for all). Also, on multivariate analysis the baseline VWF value was the only predictor for an early response to BV therapy. Furthermore, D-dimer and prothrombin fragment 1+2 were predictive factors for OS while Karnofsky performance status resulted predictive for PFS. VWF antigen value is a possible predictive biomarker for an early 3 month response to BV therapy in recurrent glioma. PMID- 29594658 TI - A glassy carbon electrode modified with poly(2,4-dinitrophenylhydrazine) for simultaneous detection of dihydroxybenzene isomers. AB - 2,4-Dinitrophenylhydrazine (DNPH) was electropolymerized on the surface of an anodized glassy carbon electrode by cyclic voltammetry. The anodized electrode has a highly electroactive surface due to the creation of chemically functionalized graphitic nanoparticles, and this facilitates the formation of poly-DNPH via radical polymerization. Poly-DNPH displays excellent redox activity due to the presence of nitro groups on its backbone. These catalyze the electro oxidation of hydroquinone (HQ) and catechol (CT). The peak-to-peak separation is around 109 mV, while a bare GCE cannot resolve the peaks (located at 165 and 274 mV vs. Ag/AgCl). Sensitivity is also enhanced to ~1.20 and 1.19 MUA.cm-2.MUM-1, respectively. The sensor has a linear response that covers the 20-250 MUM concentration range for both HQ and CT, with 0.75 and 0.76 MUM detection limits, respectively, at simultaneous detection. Commonly present species do not interfere. Graphical abstract A novel conducting poly(2,4-dinitrophenylhydrazine) modified anodized glassy carbon electrode (pDNPH/AGCE) was developed by electrochemical method. The electro-catalytic activity of pDNPH/AGCE sensor was investigated for the selective and simultaneous electrochemical detection of hydroquinone (HQ) and catechol (CT), which revealed high sensitivities and low detection limits with excellent stability.

AB - Deciding between increased cancer screening or prophylactic surgery and the timing of such procedures can be a difficult and complex process for women with BRCA mutations. There are gaps in our understanding of involvement of others in the decision-making process for women with BRCA mutations. This study evaluated the management decision-making process of women with BRCA mutations, focusing on the involvement of others. Grounded theory was used to analyze and code risk management decision-making information from interviews with 20 BRCA mutation carriers. Unaffected at-risk participants with a BRCA mutation, those under age 40, and those with no children described having a difficult time making risk management decisions. Physicians were an integral part of the decision-making process by providing decisional support and management recommendations. Family members and other mutation carriers filled similar yet distinct roles by providing experiential information as well as decisional and emotional support for carriers. Participants described genetic counselors as short-term providers of risk information and management recommendations. The study findings suggest that unaffected at-risk women, women under 40, and those who do not have children may benefit from additional support and information during the decision-making process. Genetic counselors are well trained to help women through this process and connect them with resources, and may be under-utilized in long-term follow-up for women with a BRCA mutation. PMID- 29594660 TI - Macroemulsion-based dispersive magnetic solid phase extraction for preconcentration and determination of copper(II) in gasoline. AB - A new method referred to as microemulsion-based Dispersive Magnetic Solid-Phase Extraction (MDM-SPE) is presented for use in the extraction and preconcentration of metal ions from complex organic matrices. MDM-SPE combines the features of magnetic nanoparticles (MNPs) and microemulsions. It was successfully applied to the extraction of copper(II) from gasoline prior to its determination by Graphite Furnace Atomic Absorption Spectrometry (GF-AAS). The material for use in MDM-SPE was obtained by first functionalizing MNPs of the type Fe3O4@Al2O3 with sodium dodecyl sulfate and the chelator 1-(2-pyridylazo)-2-naphthol (PAN) dispersed in 1 propanol. The resulting functionalized magnetic MNPs were dispersed in a microemulsion prepared from gasoline, buffer, and 1-propanol. After waiting for 5 s (during which the formation of the copper complex on the MNPs is complete), the MNPs are magnetically separated. The complex was then eluted with 2 mol L-1 HNO3, and the eluate submitted to GF-AAS. Various parameters were optimized. Copper(II) can be quantified by this method over a linear range that extends from 2.0 to 10.0 MUg.L-1. Other figures of merit include (a) a 37 ng.L-1 detection limit, (b) a repeatability of 1.1%, (c) a reproducibility of 2.1%, and (d) an enrichment factor of nine. The high surface-to-volume ratio of the microemulsion containing the dispersed magnetic sorbent warrants an efficient contact for reaction between copper(II) and the complexing agent, and this results in fast (about 40 s) extraction and pre-concentration of copper(II). MDM-SPE is accurate, precise and efficient. Microemulsions do not break down, and phase separation, heating, laborious, and time-consuming sample preparation, and incorporation of impurities into the graphite furnace (which can generate inaccuracies in GF-AAS analysis) are not needed. Graphical abstract Schematic of a new method for Microemulsion based Dispersive Magnetic Solid-Phase Extraction (MDMSPE) using functionalized magnetic nanoparticles (FMNPs). It was applied to the preconcentration of copper(II) in gasoline. PMID- 29594661 TI - Advances in the use of carbonaceous materials for the electrochemical determination of persistent organic pollutants. A review. AB - Persistent organic pollutants (POPs) are key pollutants due to their persistence, refractory biodegradation, high toxicity and bioaccumulation in the food chain. This review (with 93 refs.) covers the progress made in the past decades in the application of carbonaceous materials for electrochemical detection of POPs as listed in the Stockholm Convention. Following an introduction into the field, typical carbonaceous materials for use in electrodes are discussed, with subsection on carbon nanotubes, graphene, reduced graphene oxide, graphitic carbon nitride and carbon dots. This is followed by a section on application of carbonaceous materials in electrochemical detection, with subsections on the use of carbon nanotubes, of (doped-) graphene, of reduced graphene oxide, of graphitic carbon nitride, and of carbon dots. The review concludes with conclusions and future perspectives. The detection mechanisms of POPs are also discussed.

PMID- 29594662 TI - Bare eye detection of Hg(II) ions based on enzyme inhibition and using mercaptoethanol as a reagent to improve selectivity. AB - The authors describe a colorimetric method for the determination of Hg2+ ions based on the inhibition of the activity of the enzyme urease. The pH value of solution increases when urease hydrolyzes urea, which can be visualized by adding a pH indicator such as Phenol Red (PhR). Mercaptoethanol as a typical thiol is added to the system to improve selectivity because it binds metal ions and then - unlike the Hg2+ mercaptoethanol complex - does not inhibit urease. Hence, the color of the pH indicator PhR turns from yellow to pink as the solution becomes alkaline. The Hg2+ mercaptoethanol complex, in contrast, strongly inhibits urease and the color of the solution remains yellow. The findings were used to design a photometric assay based on the measurement of the ratio of absorptions of PhR at 558 nm and 430 nm. It has a linear response over the 25 to 40 nM Hg2+ concentration range and a 5 nM detection limit. This is well below the guideline values of Hg2+ specified by the US Environmental Protection Agency and the World Health Organization for drinking water (10 nM and 30 nM, respectively). The method was employed to the determination of Hg2+ in water samples spiked with 10 nM levels of Hg2+ where color changes still can be observed visually. Graphical Abstract Schematic presentation of a colorimetric method for the ultrasensitive detection of Hg2+ based on the inhibition of urease activity. Mercaptoethanol is used to improve the selectivity. Even at Hg2+ concentrations as low as 5 nM, the color change still can be easily observed by bare eyes. PMID- 29594663 TI - A composite consisting of microporous carbon and cobalt(III) oxide and prepared from zeolitic imidazolate framework-67 for voltammetric determination of ascorbic acid. AB - A nanoporous carbon/cobalt oxide (NPC/Co3O4) composite was synthesized from a single-precursor (zeolitic imidazolate framework-67). Transmission electron microscopy showed that the Co3O4 nanoparticles with an average particle size of 10 nm (+/-2 nm) were well dispersed in the NPC matrix. However, in a few places, Co3O4 nanoparticles were aggregated. The composite shows outstanding performance in terms of electrooxidation of ascorbic acid (AA) in phosphate buffer of pH 7.0. The differential pulse voltammetric response of the composite electrode (at 0.12 V vs. SCE) is linear in the 2-240 MUM AA concentration range, with a 20 nM detection limit. The electrode exhibits high sensitivity (0.13 MUA.MUM.cm-2), reliable reproducibility, and good selectivity. The method, when applied to the direct determination of AA in vitamin C tablets, gave recoveries between 98.0 and 102.0%. Graphical abstract A nanoporous carbon composite decorated with Co2O3 nanoparticles was prepared from a single precursor (the zeolitic imidazolate framework-67).

PMID- 29594664 TI - Selective extraction of theophylline from plasma by copper-doped magnetic microspheres prior to its quantification by HPLC. AB - The authors describe the preparation of copper-doped magnetic microspheres (Cu Fe3O4) by a solvothermal method. Due to their good magnetic property and high affinity for compounds containing an imidazole moiety (containing N-H), they are excellent adsorbents for such compounds as tested by eighteen compounds. Specifically, a method has been developed for magnetic solid-phase extraction (MSPE) of theophylline (TP) from plasma. The method enables selective enrichment of TP over many potential interferents that can occur in plasma. Following elution with alkaline methanol, TP was quantified by HPLC-UV at a detection wavelength of 272 nm. Under the optimized conditions, a linear response is found for the 0.02 to 20 MUg.mL-1 concentration range, and the limit of detection is as low as 3 ng.mL-1. Recoveries from spiked samples range from 91.2 to 100.4%, and the repeatabilities are between 2.9 and 12% (for n = 6). The method was successfully applied to the determination of TP in rabbit and rat plasma. Graphical abstract Copper-doped magnetic microspheres are described that show good magnetic property and high affinity for compounds containing an imidazole moiety (containing an N-H group). They were successfully applied to the selective extraction of theophylline in plasma. PMID- 29594665 TI - Gold nanoparticle based photometric determination of tobramycin by using new specific DNA aptamers. AB - A magnetic bead-based SELEX was applied to identify 37 single-stranded DNA aptamers specific for tobramycin after ten rounds of selection. The aptamers were classified into nine families according to sequence analysis. Among them, several aptamers with typical sequences were selected and their dissociation constants (Kds) were determined by a fluorescent method. An aptamer termed "Ap 32", with a Kd value of 56.8 +/- 4.6 nM, possesses the highest affinity and satisfactory specificity. Theoretical modeling showed that nucleotides 14-18 and 26-29 play a most significant role in the interaction between aptamer and tobramycin. Subsequently, the sequence of Ap 32 was optimized through rationally designed truncation. The truncated aptamer Ap 32-2 consists of 34 nucleotides and has a Kd that is similar to the original one. It was chosen as the optimal aptamer for use in the assay and was immobilized on gold nanoparticles. On addition of tobramycin, the color turns from red to purple. The findings were used to design a photometric assay (best performed at 520 nm) that has a linear response in the 100 nM to 1.4 MUM concentration range, with a 37.9 nM detection limit. The method was successfully applied to the determination of tobramycin in (spiked) honey samples. Graphical abstract A 34-nucleotide aptamer specific for tobramycin was obtained through magnetic beads-based systematic evolution of ligands by exponential enrichment (SELEX) and structural analysis-based rational post-SELEX truncation, and then applied to the determination of tobramycin using a gold nanoparticle-based photometric assay.

AB - A new method is described for the determination of the pesticide lambda cyhalothrin (LC). It combines SERS detection with molecular imprinting and largely improves selectivity. A multilayer surface imprinted nanocomposite was synthesized in two steps on a nanostructure of type SiO2@rGO@Ag acting as a substrates. Firstly, the surface of the SiO2@rGO@Ag composite was modified with self-polymerized dopamine. Secondly, surface-initiated polymerization was carried out to prepare a molecularly imprinted polymer (MIP) using LC as the template. The use of this SiO2@rGO@Ag-MIP allows for excellent SERS based detection and has high selectivity for LC. The Raman intensity and LC concentration present perfect linear relationship between 10-5 to 10-9 mol L-1 and the detection limit is 3.8*10-10 mol L-1. All the procedures are conducted in aqueous or ethanol solution. Graphical abstract Schematic of a new method for determination of the pesticide lambda-cyhalothrin.

AB - The authors describe a multifunctional magnetic molecularly imprinted phosphorescent nanoparticle probe for the selective determination of 2,4,6 trichlorophenol (2,4,6-TCP). The probe consists of a magnetite (Fe3O4) core that is coated with a molecularly imprinted polymer doped with Mn-doped ZnS quantum dots (QDs). The MIP was obtained by copolymerization of acrylamide, ethylene glycol dimethacrylate, and 2,4,6-TCP. The resulting nanoprobe shows strong phosphorescence (with excitation/emission peaks at 320/594 nm) due to the presence of the QDs, good magnetism, and high selectivity for 2,4,6-TCP. Under optimal detection condition, response is linear in the 0.1-30 MUmol L-1 2,4,6-TCP concentration range. The imprinting factor is 8.84, and the detection limit is 35 nmol L-1. The method was successfully applied to the determination of 2,4,6-TCP in spiked river water and waste water. Graphical abstract Schematic of a multifunctional phosphorescent probe for 2,4,6-trichlorophenol. It consists of a magnetic core coated with a molecularly imprinted polymer shell containing Mn(II) doped ZnS quantum dots whose room-temperature phosphorescence is quenched by 2,4,6-trichlorophenol.

AB - The authors describe an ethylene glycol assisted precipitation method for synthesis of Er(III)/Yb(III)-doped BiF3 nanoparticles (NPs) at room temperature. Under 980-nm light irradiation, the NPs emit upconversion (UC) emission of Er(III) ions as a result of a two-photon absorption process. The temperature dependent green emissions (peaking at 525 and 545 nm) are used to establish an unambiguous relationship between the ratio of fluorescence intensities and temperature. The NPs have a maximum sensitivity of 6.5 * 10-3 K-1 at 619 K and can be applied over the 291-691 K temperature range. The results indicate that these NPs are a promising candidate for optical thermometry.

AB - The authors describe an electrochemical DNA nanosensor based on the use of single gold nanowire electrodes (AuNWEs). The probe DNA is immobilized on the AuNWE via Au-S bonds that are formed between thiol-terminated DNA and the gold surface. Single AuNWEs were prepared by an improved laser-assisted pulling method and hydrofluoric acid etching. The nanoelectrodes were characterized by cyclic voltammetry and COMSOL simulation. Square wave voltammetry was used to monitor the DNA hybridization event between probe DNA and target DNA by using Methylene Blue (MB) as an intercalator of dsDNA. Under optimal conditions, the peak current for MB (best measured at a potential of -0.2 V vs. Ag/AgCl) increases linearly with the logarithm of the analyte concentration in the 1.0 f. to 10 nM range, with a 0.48 fmM detection limit at an S/N ratio of 3. The assay is highly selective, reproducible and stable. Considering the small overall dimensions and high sensitivity, this nanoelectrode potentially can be applied to in-vivo sensing of DNA inside living cells Graphical abstract Schematic presentation of an electrochemical DNA nanosensor using single gold nanowire electrodes and based on the interaction of thiol-terminated DNA and gold surface.

AB - Researchers often refer to "research integrity", "scientific integrity", "research misconduct", "scientific misconduct" and "research ethics". However, they may use some of these terms interchangeably despite conceptual distinctions. The aim of this paper is to clarify what is signified by several key terms related to research integrity, and to suggest clearer conceptual delineation between them. To accomplish this task, it provides a conceptual analysis based upon definitions and general usage of these phrases and categorization of integrity-breaching behaviours in literature and guidelines, including clarification of the different domains and agents involved. In the first part of the analysis, following some initial clarifications, I explore the distinction between internal and external rules of integrity. In the second part, I explore the distinction between integrity and lack of misconduct, before suggesting a recategorisation of different types of integrity breach. I conclude that greater clarity is needed in the debate on research integrity. Distinguishing between scientific and research integrity, reassessing the relative gravity of different misbehaviours in light of this distinction, and recognising all intentional breaches of integrity as misconduct may help to improve guidelines and education.

AB - The authors describe the synthesis of water-soluble and fluorescent graphene oxide quantum dots via acid exfoliation of graphite nanoparticles. The resultant graphene oxide quantum dots (GoQDs) were then modified with folic acid. Folic acid receptors are overexpressed in cancer cells and hence can bind to functionalized graphene oxide quantum dots. On excitation at 305 nm, the GoQDs display green fluorescence with a peak wavelength at ~520 nm. The modified GoQDs are non-toxic to macrophage cells even after prolonged exposure and high concentrations. Fluorescence lifetime imaging and multiphoton microscopy was used (in combination) to image HeCaT cells exposed to GoQDs, resulting in a superior method for bioimaging.

PMID- 29594672 TI - Hyaluronic acid functionalized nanostructured sensing interface for voltammetric determination of microRNA in biological media with ultra-high sensitivity and ultra-low fouling. AB - An electrochemical biosensor for the detection of microRNA was prepared via chemical grafting of a Methylene Blue labeled reporter (MB-Rep) duplex onto a nanostructured surface that was obtained by electrodeposition of cobalt oxide and poly(o-phenylenediamine). This is followed by the attachment of hyaluronic acid and gold nanoclusters. In the presence of the target (microRNA), the probe-target duplex and the MB-Rep hairpin are formed. These will displace the labeled reporter from the sensor surface, and this results in a decrease of the amperometric signal for MB at a typical working voltage of -0.28 V (vs. Ag/AgCl). The electrode modified with hyaluronic acid possesses a large electroactive surface area and an excellent antifouling property. This makes it useful for ultrasensitive quantitation of microRNA even in complex biological media. The sensor has a linear response in the 100 f. to 0.1 MUM microRNA concentration range, and a 33.3 f. detection limit. It was successfully applied to the determination of microRNA in cancer cells.

AB - It is shown that triangular silver nanoplates (TAgNPs) are viable colorimetric probes for the fast, sensitive and selective detection of Hg(II). Detection is accomplished by reducing Hg(II) ions to elemental Hg so that an Ag/Hg amalgam is formed on the surface of the TAgNPs. This leads to the inhibition of the etching TAgNPs by chloride ions. Correspondingly, a distinct color transition can be observed that goes from yellow to brown, purple, and blue. The color alterations extracted from the red, green, and blue part of digital (RGB) images can be applied to the determination of Hg(II). The relationship between the Euclidean distances (EDs), i.e. the square roots of the sums of the squares of the DeltaRGB values, vary in the 5 nM to 100 nM Hg(II) concentration range, and the limit of detection is as low as 0.35 nM. The color changes also allow for a visual estimation of the concentrations of Hg(II). The method is simple in that it only requires a digital camera for data acquisition and a Photoshop software for extracting RGB variations and data processing. Graphical abstract Hg2+ detection was achieved by anti-etching of TAgNPs caused by the formation of silver amalgam, along with vivid multicolor variations from yellow to brown, purple, and eventually to be blue.

The postal survey was followed up by a telephone call to complete missing surveys. The Client Satisfaction Questionnaire has a 4-point Likert scale with a minimum score of 8 and maximum score (highest satisfaction) of 32. RESULTS: Fourteen Client Satisfaction questionnaires were returned indicating a response rate of 48%. The mean age of the children who attended CAP was 10.84 years. The mean CSQ-8 score was 25.6 (95% CI 22.0-29.3) with a range of 8 to 32. Eighty-five percent of parents indicated that they were satisfied on all questions regarding the service of CAP their child received. One of 29 parents attended for interview and 4 themes were identified in the interview: (1) the importance of the child's opinion, (2) behavioural change occurred during and after CAP, (3) the parent would recommend CAP to others, and (4) parental expectations of therapy and level of engagement. CONCLUSION: Parents are satisfied with the Vasarhelyi method of Child Art Psychotherapy.

AB - A study is presented on the binding kinetics and mechanism of the adsorption of dsDNA on citrate-capped gold nanoparticles (AuNPs). Methods include fluorescence titration, isothermal calorimetry (ITC) titration, dynamic light scattering and gel electrophoresis. It is found that the fluorescence of probe DNA (labeled with Rhodamine Green and measured at excitation/emission peaks of 498/531 nm) is quenched by addition of AuNPs. The Stern-Volmer quenching constant (Ksv) is 1.67 * 10^9 L.mol-1 at 308 K and drops with increasing temperature. The quenching mechanism is mainly static. The results of both fluorescence titrations and ITC show negative values for DeltaH and DeltaS values. This shows ion-induced dipole dipole interaction to be the main attractive forces between dsDNA and AuNPs, while electrostatic interactions result in repulsion. The repulsive forces lead to a lower affinity between dsDNA and AuNPs (compared to single-strand DNA). It is also found that dsDNA can prevent the aggregation of AuNPs which is accompanied by a color change from red into blue. The visual detection limit with bare eyes for dsDNA1 is 36 pM. Based on these findings, a colorimetric method was developed to detect the proto-oncogene of serine/threonine-protein kinase B-Raf V600E point mutation in HT29, Ec109, A549, Huh-7 and SW480 cell lines. Graphical abstract Schematic of the salt-induced aggregation of uncapped gold nanoparticles (AuNPs) which leads to a color change from red to blue. If the AuNPs are coated with dsDNA, aggregation is suppressed. PMID- 29594676 TI - Patient and health professional satisfaction with an interdisciplinary patient safety program. AB - Background Measuring humanistic outcomes is an important component of valuating healthcare services. There is a paucity of data on satisfaction with pharmacist implemented clinical services in long-term care settings. Objective To evaluate patient and health professional (HP) satisfaction with an interdisciplinary patient safety program performed in elderly patients with polypharmacy admitted to a long-term care hospital (LTCH). Method An interventional, longitudinal, prospective study was conducted in a Spanish LTCH. Pharmacist conducted the pharmacotherapy follow-up (reconciliation, pharmacotherapeutic optimization and educational interviews). Two satisfaction surveys were designed on a 10-point Likert-type scale. The patient survey was administered at discharge. The HP survey included the following dimensions: knowledge and program importance, pharmacist skills and pharmacist contributions to the interdisciplinary team. A reliability analysis was performed. Results 123 surveys were completed and returned; 74 patient surveys (response rate 97.4%) and 49 HP surveys (response rate 98.0%). The overall mean score of the patient survey was 9.46 +/- 0.87, resulting in 82.4% very satisfied and 17.6% satisfied. The overall mean score of the HP survey was 8.85 +/- 1.42, resulting in 65.3% very satisfied and 30.6% satisfied. Conclusion Elderly patients with polypharmacy and HPs reported high levels of satisfaction with the interdisciplinary patient safety program implemented in an LTCH. This positive response supports the value of pharmacists for managing older high-risk populations. PMID- 29594677 TI - Monitoring of gentamicin serum concentrations in obstetrics and gynaecology patients in Namibia. AB - Background Therapeutic drug monitoring is frequently used to optimize the gentamicin dose. Objective The study investigated whether a 240 mg once daily standard dose achieves the recommended target serum gentamicin concentrations. Setting The prospective, observational study took place in the 2 major public hospitals in Namibia. Method Twenty-nine female patients receiving a standard dose (240 mg gentamicin once daily) participated in the study. Two blood samples were withdrawn to estimate gentamicin pharmacokinetic parameters. Serum creatinine was used to calculate creatinine clearance with the Cockcroft-Gault formula (CLcr), and estimate glomerular filtration rate (eGFR) by the Modified Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Main outcome measure The outcome measure was the proportion of patients receiving 240 mg gentamicin once daily having Cmax values above 15 mg/L. Results Total body weight (TBW) and body mass index were highly variable: 43-115 kg, and 17.3-41.3 kg/m2, respectively. The gentamicin dose normalized for TBW (adjusted body weight for obese patients) was relatively low, i.e. 4.2 +/- 0.8 mg/kg (mean SD). Gentamicin Cmax was 14.4 +/- 4.7 mg/L; only 9 patients (31%) had a Cmax > 15 g/mL. eGFR (MDRD-4) correlated well with CLcr, but eGFR (EPI-CKD) formula showed systematic deviations from CLcr. Conclusions (1) a standard 240 mg dose results in gentamicin Cmax values below 15 mg/L in the majority of the patients, (2) eGFR formulas to estimate kidney function will have to be evaluated for their usefulness in the Namibian patient population. PMID- 29594678 TI - Aptamer based fluorometric beta-lactoglobulin assay based on the use of magnetic nanoparticles and carbon dots. AB - The authors describe a fluorometric aptamer based assay for detecting beta lactoglobulin by using carbon dots (C-dots) as a signal indicator. The aptamer was immoblized on magnetite (Fe3O4) nanoparticles (MNPs), and the C-dots served as a label for the complementary oligonucleotide (cDNA). The assay is based on the hybridization that takes place between aptamer and cDNA. In the presence of beta-lactoglobulin (beta-LG), the aptamer preferentially binds to beta-LG, and this leads to a partial release of the C-dots-cDNA into the solution. After magnetic separation, the supernatant of the solution contains the released C-dots cDNA which are quantified by fluorometry, best under excitation/emission wavelengths of 354/447 nm. Under the optimal conditions, the fluorescence intensity is proportional to the logarithm of the beta-LG concentration in the 0.25 to 50 ng mL-1 range, with a 37 pg mL-1 detection limit. The method was successfully applied to the determination of beta-LG in hypoallergenic formulations, and the results demonstrated that this assay is a promising tool in food quality control. Conceivably, it also provides the opportunity for detection of other analytes. Graphical abstract Schematic of a novel aptamer based fluorometric beta-lactoglobulin assay based on the use of magnetite (Fe3O4) nanoparticles (MNPs) and carbon dots (C-dots). C-dots were used as a signal indicator and Fe3O4 MNPs acted as a magnetic separator. This assay exhibits high sensitivity and selectivity with a detection limit as low as 37 pg mL-1.

AB - Hybrids consisting of silver nanoparticles (in varying fractions) and of TiOx/ZnO were prepared via top-down ion beam sputtering (IBS) deposition on silicon substrates. The deposited nanomaterials were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. It is shown that such composites represent a viable substrate for use in both surface enhanced Raman spectroscopy (SERS) and surface enhanced infrared absorption spectroscopy (SEIRAS), as exemplarily shown for crystal violet as the model analyte. The C-H bending mode at about 1181 cm-1 and the C-N vibration at 1361 cm-1 observed in the SERS and SEIRAS spectra, respectively, have been used as analytical signal. The substrate consisting of TiOx NPs with 33% fraction of silver provides the strongest enhancement in SERS (up to 10,000-fold), while TiOx/AgNPs with thickness of 2 and 1 nm in ion beam sputtering, respectively, provides the best sensitivity in SEIRAS. The substrates also display photocatalytic activity as shown by the degradation of adsorbed crystal violet under ultraviolet irradiation. Graphical abstract Schematic of the preparation of hybrid substrates consisting of Ag and TiOx/ZnO nanoparticles via ion beam sputtering deposition. They were applied in both surface enhanced Raman and surface enhanced infrared absorption spectroscopies using crystal violet as model analyte, showing enhancements up to >10,000-fold in Raman.

AB - A voltammetric analytical assay for the selective quantification of vanillin is described. It is based on the use of a gold nanoparticle-modified screen-printed carbon electrode (SPCE) modified with graphene quantum dots (GQD) in a Nafion matrix. The GQD were synthesized by an acidic thermal method and characterized by UV-Vis, photoluminescence, and FTIR spectroscopy. The modified SPCE displays a strongly enhanced response to vanillin. Linear sweep voltammetry (LSV) and differential pulse voltammetry (DPV) were applied to optimize the methods. The analytical assay has linear responses in the 13 to 660 MUM and 0.66 to 33 MUM vanillin concentration ranges. The detection limits are 3.9 MUM and 0.32 MUM when using LSV and DPV, respectively. The analytical assay is selective and stable. It was applied to the determination of vanillin in several food samples with satisfactory results. Recoveries from spiked samples ranged between 92.1 and 113.0%. Graphical abstract The selective and sensitive quantification of vanillin is carried out by the use of a gold nanoparticle-modified screen-printed carbon electrode modified with graphene quantum dots in a Nafion matrix.

AB - The article describes a reusable biosensor for Pb(II) ions. A duplex DNA with a terminal amino group and containing a G-quadruplex (G4) aptamer was covalently conjugated to single walled carbon nanotubes on a field effect transistor (FET). The detection scheme is based on the despiralization of the DNA duplex because Pb(II) can induce the G4 aptamer to form a stabilizing G4/Pb(II) complex. This structural change affects the electrical conductivity of SWNTs which serves as the analytical signal. The biosensor was characterized via scanning electron microscopy, Raman, UV-vis, and voltage-current profiles. Under optimized conditions, the relative resistance at 0.02 V increases linearly with the logarithm of the Pb(II) concentration in the range from 1 ng.L-1 to 100 MUg.L-1, and the limit of detection is 0.39 ng.L-1. Compared to other sensors, this oner demonstrates superior simplicity, sensitivity, and selectivity even in mixtures of heavy metal ions. It was applied to the determination of Pb(II) in (spiked) water and soil samples and gave good results. Graphical abstract Schematic of the fabrication a biosensor for Pb(II). It is making use of an SWNT-based FET, G4-DNA and complementary DNA with an amino group. Pb(II) can despiralize the DNA duplex to form a G-quadruplex which affects the electrical conductivity of SWNTs. After each detection, the single complementary strand DNA can rebind the G4-DNA, which makes the biosensor reusable. PMID- 29594682 TI - A glassy carbon electrode modified with N-doped carbon dots for improved detection of hydrogen peroxide and paracetamol. AB - Nitrogen doped carbon dots (NCDs) were synthesized using a low temperature approach and used to modify a glassy carbon electrode (GCE) via dipping. The oxygen groups on the surface of the NCDs, and the charge delocalization of the NCDs warrant an excellent electrocatalytic activity of the GCE toward oxidation of paracetamol (PA) and reduction of H2O2. PA and H2O2 were detected at 0.34 V and -0.4 V (both vs. Ag/AgCl) using differential pulse voltammetry and amperometric I-T measurement, respectively. The modified GCE has a linear response to PA in the 0.5 to 600 MUM concentration range, and to H2O2 in the 0.05 MUM to 2.25 mM concentration range. The detection limits are 157 nM and 41 nM, respectively. In our perception, the modified GCE holds promise for stable, selective and sensitive determination of PA and H2O2 in pharmaceutical analysis. Graphic abstract Nitrogen doped carbon dots (NCDs) were synthesized and used to modify a glassy carbon electrode. Surface functional groups on NCDs can trigger electrocatalytic reactions toward paracetamol oxidation and H2O2 reduction with high sensitivities. PMID- 29594683 TI - Visual and colorimetric determination of H2O2 and glucose based on citrate promoted H2O2 sculpturing of silver nanoparticles. AB - Isotropic silver nanoparticles (iAg NPs) can be easily prepared at low costs, have a low electrochemical potential and high extinction coefficient. An effective colorimetric assay for H2O2 is reported here based on the finding that H2O2 can induce the shape transformation of citrate-capped iAg NPs with the help of citrate. The substantial shape variation affords an apparent surface plasmon resonance (SPR) shift, accompanied by a vivid color change from light yellow to mauve. The color change can be observed visually if the concentration of H2O2 is 2 MUM or higher. A good linear relationship was obtained over the concentration range of 0.2-32 MUM with a limit of detection of 90 nM. By making use of glucose oxidase, the method is further extended to glucose detection. Glucose at a concentration as low as 10 MUM can be well determined with bare eyes. Benefitting from the high selectivity, the detection of glucose in human serum is realized, and the results are in good agreement with those provided by a clinical analyzer. Graphical abstract Schematic presentation of a colorimetric assay for H2O2 and glucose based on citrate-promoted H2O2-mediated shape transformation of the isotropic silver nanoparticles (Ag NPs). The shape variation of isotropic Ag NPs induces a color change from light yellow to mauve.

AB - In this study, the effect of adipose tissue stem cells (ASCs) on the growth of acute lymphoblastic leukemia (ALL) cells was examined in an in vivo model. We established ALL cell lines expressing firefly luciferase (ALL/fLuc) by lentiviral infection that were injected intraperitoneally to NOD/SCID mice. The luciferase activities were significantly higher in mice co-injected with 105 ALL/fLuc cells and ASCs than in those injected with ALL/fLuc cells alone. Co-injection of 105 ALL/fLuc cells and ASCs in differing ratios into mice gradually increased the bioluminescence intensity in all groups, and mice co-injected with 1 or 2 * 106 ASCs showed higher bioluminescence intensity than those receiving lower numbers. Interestingly, in the mice injected with 105 or 107 ALL/fLuc cells alone, the formation of tumor masses was not observed for at least five weeks. Moreover, co injection of 107 ALL/fLuc cells and 5 * 105 ASCs into mice increased the bioluminescence intensity in all groups, and showed significantly higher bioluminescence intensity compared to mice co-injected with human normal fibroblast HS68 cells. Overall, ASCs promote the growth of ALL cells in vivo, suggesting that ASCs negatively influence hematologic malignancy, which should be considered in developing cell therapy using ASCs. PMID- 29594685 TI - Climate change impacts detection in dry forested ecosystem as indicated by vegetation cover change in -Laikipia, of Kenya. AB - The objective of the study was to detect and identify land cover changes in Laikipia County of Kenya that have occurred during the last three decades. The land use types of study area are six, of which three are the main and the other three are the minor. The main three, forest, shrub or bush land and grassland, changed during the period, of which grasslands reduced by 5864 ha (40%), forest by 3071 ha (24%) and shrub and bush land increased by 8912 ha (43%). The other three minor land use types were bare land which had reduced by 238 ha (45%), river bed vegetation increased by 209 ha (72%) and agriculture increased by 52 ha (600%) over the period decades. Differences in spatiotemporal variations of vegetation could be largely attributed to the effects of climate factors, anthropogenic activities and their interactions. Precipitation and temperature have been demonstrated to be the key climate factors for plant growth and vegetation development where rainfall decreased by 200 mm and temperatures increased by 1.5 degrees C over the period. Also, the opinion of the community on the change of land use and management was attributed to climate change and also adaptation strategies applied by the community over time. For example unlike the common understanding that forest resources utilisation increases with increasing human population, Mukogodo dry forested ecosystem case is different in that the majority of the respondents (78.9%) reported that the forest resource use was more in that period than now and also a similar majority (74.2%) had the same opinion that forest resource utilisation was low compared to last 30 years. In Yaaku community, change impacts were evidenced and thus mitigation measures suggested to address the impacts which included the following: controlled bush management and indigenous grass reseeding programme were advocated to restore original grasslands, and agricultural (crop farming) activities are carried out in designated areas outside the forest conservation areas (ecosystem zoning) all in consultation with government (political class), community and other stakeholders. Groups are organised (environmental management committee) to address conservation, political and vulnerability issues in the pastoral dry forested ecosystem which will sustain pastoralism in the ecosystem. PMID- 29594686 TI - Copper nanoclusters capped with tannic acid as a fluorescent probe for real-time determination of the activity of pyrophosphatase. AB - The authors show that copper nanoclusters capped with tannic acid (TA-CuNCs) are viable fluorescent probes for the determination of the activity of pyrophosphatase (PPase). The fluorescence of the TA-CuNCs is quenched by Fe(III) but restored on subsequant addition of pyrophosphate (PPi). If, however, PPi is split by PPase into two phosphate ions, the fluorescence of the TA-CuNCs is quenched again. Under optimized conditions, fluorescence intensity linearly correlates with the activity of PPase in the range from 0.50 to 18.0 U L-1 with a detection limit of 0.19 U L-1. The method was employed to the determination of PPase in spiked human serum samples and gave satisfactory results. Graphical abstract Schematic illustration of fluorometric assay for PPase activity. It is based on the finding that pyrophosphate (PPi) can restore the Fe3+-quenched TA CuNC fluorescence. PPi is formed by enzymatic action of PPasei.

AB - Ablation is a common procedure for treating patients with cancer, cardiac arrhythmia, and other conditions, yet it can cause collateral injury to the respiratory diaphragm. Collateral injury can alter the diaphragm's properties and/or lead to respiratory dysfunction. Thus, it is important to understand the diaphragm's physiologic and biomechanical properties in response to ablation therapies, in order to better understand ablative modalities, minimize complications, and maximize the safety and efficacy of ablative procedures. In this study, we analyzed physiologic and biomechanical properties of swine respiratory diaphragm muscle bundles when exposed to 5 ablative modalities. To assess physiologic properties, we performed in vitro tissue bath studies and measured changes in peak force and baseline force. To assess biomechanical properties, we performed uniaxial stress tests, measuring force-displacement responses, stress-strain characteristics, and avulsion forces. After treating the muscle bundles with all 5 ablative modalities, we observed dose-dependent sustained reductions in peak force and transient increases in baseline force-but no consistent dose-dependent biomechanical responses. These data provide novel insights into the effects of various ablative modalities on the respiratory diaphragm, insights that could enable improvements in ablative techniques and therapies. PMID- 29594688 TI - Coupled Morphological-Hemodynamic Computational Analysis of Type B Aortic Dissection: A Longitudinal Study. AB - Progressive false lumen aneurysmal degeneration in type B aortic dissection (TBAD) is a complex process with a multi-factorial etiology. Patient-specific computational fluid dynamics (CFD) simulations provide spatial and temporal hemodynamic quantities that facilitate understanding this disease progression. A longitudinal study was performed for a TBAD patient, who was diagnosed with the uncomplicated TBAD in 2006 and treated with optimal medical therapy but received surgery in 2010 due to late complication. Geometries of the aorta in 2006 and 2010 were reconstructed. With registration algorithms, we accurately quantified the evolution of the false lumen, while with CFD simulations we computed several hemodynamic indexes, including the wall shear stress (WSS), and the relative residence time (RRT). The numerical fluid model included large eddy simulation (LES) modeling for efficiently capturing the flow disturbances induced by the entry tears. In the absence of complete patient-specific data, the boundary conditions were based on a specific calibration method. Correlations between hemodynamics and the evolution field in time obtained by registration of the false lumen are discussed. Further testing of this methodology on a large cohort of patients may enable the use of CFD to predict whether patients, with originally uncomplicated TBAD, develop late complications. PMID- 29594689 TI - Development of a Metric for Predicting Brain Strain Responses Using Head Kinematics. AB - Diffuse brain injuries are caused by excessive brain deformation generated primarily by rapid rotational head motion. Metrics that describe the severity of brain injury based on head motion often do not represent the governing physics of brain deformation, rendering them ineffective over a broad range of head impact conditions. This study develops a brain injury metric based on the response of a second-order mechanical system, and relates rotational head kinematics to strain based brain injury metrics: maximum principal strain (MPS) and cumulative strain damage measure (CSDM). This new metric, universal brain injury criterion (UBrIC), is applicable over a broad range of kinematics encountered in automotive crash and sports. Efficacy of UBrIC was demonstrated by comparing it to MPS and CSDM predicted in 1600 head impacts using two different finite element (FE) brain models. Relative to existing metrics, UBrIC had the highest correlation with the FE models, and performed better in most impact conditions. While UBrIC provides a reliable measurement for brain injury assessment in a broad range of head impact conditions, and can inform helmet and countermeasure design, an injury risk function was not incorporated into its current formulation until validated strain based risk functions can be developed and verified against human injury data. PMID- 29594690 TI - Associations Between Copper and Zinc and Risk of Hypertension in US Adults. AB - Evidence linking copper and zinc to hypertension are limited and conflicting. Data from the National Health and Nutrition Examination Survey (NHANES) 2007-2014 were used. Zinc and copper intake from diet and supplements was assessed with 24 h dietary recall. Hypertension was defined as systolic blood pressure (SBP) >= 140 mmHg/diastolic blood pressure (DBP) >= 90 mmHg/treatment with hypertensive medications. In a sensitivity analysis, according to the 2017 American College of Cardiology and American Heart Association guideline, hypertension was also defined as SBP >= 130 mmHg/DBP >= 80 mmHg/treatment with hypertensive medications. A total of 17,811 adults (8430 men and 9381 women) were included. After adjustment for age, gender, body mass index (BMI), race, educational level, smoking status, family income, and total daily energy intake, the OR of hypertension for highest vs. lowest quartile intake of copper, zinc, and copper/zinc ratio was 1.11 (0.90-1.37), 1.11 (0.90-1.35), and 0.95 (0.81-1.11), respectively. In stratified analysis by BMI (< 25 kg/m2, 25-30 kg/m2, > 30 kg/m2), no significant association was found between hypertension and intakes of copper, zinc, and copper/zinc ratio (highest vs. lowest quartile) in multivariate analysis. In multivariate analysis, the OR of hypertension for highest vs. lowest quartile levels of serum copper, zinc, and copper/zinc ratio was 1.11 (0.61 2.04), 1.43 (0.84-2.44), and 0.68 (0.34-1.33), respectively. Similar results were found in the sensitivity analysis. Zinc and copper might be not independently associated with hypertension in US adults. PMID- 29594691 TI - A Review on the Role of Chromium Supplementation in Ruminant Nutrition-Effects on Productive Performance, Blood Metabolites, Antioxidant Status, and Immunocompetence. AB - With the increase in the global herd, the use of metabolic modifiers has become an important area for many researchers looking for a supraphysiological diet to improve production parameters. For improving the performance of high yielding cows, the optimal balance of all nutrients including microminerals is important. Chromium (Cr) is one of the important micronutrients which plays an important role in metabolism of ruminants. Experimental studies have found that Cr could change performance, immune responses, glucose and fatty acid metabolism, and antioxidant status in dairy cows. In some studies, Cr supplementation improved dry matter intake, milk production, and milk composition of dairy cows in the early, mid, or late stage of lactation. Also, in some studies, performance of growing animal, immune response, and some blood parameters responded positively to Cr supplementation. In conclusion, the effects of Cr supplementation on performance of ruminants are inconsistent; however, its long-term effects on health, productivity, immune system, and antioxidant activity of ruminants still need to be investigated. PMID- 29594692 TI - Effect of Organic Selenium Supplementation on Selenium Status, Oxidative Stress, and Antioxidant Status in Selenium-Adequate Dairy Cows During the Periparturient Period. AB - The periparturient period represents a stressful time for dairy cows as they transition from late gestation to early lactation. Oxidation stress occurs during this period owing to the increased metabolic activity. Antioxidants supplementation slightly above the suggested requirements may be beneficial in relieving this kind of stress. The objective of this study was to determine whether supplementing selenium (Se) yeast to diets with adequate Se concentrations affects Se status, oxidative stress, and antioxidant status in dairy cows during the periparturient period. Twenty multiparous Holstein cows were randomly divided into two groups with ten replicates in each group. During the last 4 weeks before calving, cows were fed Se-yeast at 0 (control) or 0.3 mg Se/kg dry matter (Se-yeast supplementation), in addition to Na selenite at 0.3 mg Se/kg dry matter in their rations. The concentrations of Se, reactive oxygen species (ROS), hydrogen peroxide (H2O2), hydroxyl radical, malonaldehyde (MDA), alpha-tocopherol and glutathione (GSH), the activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT), and the total antioxidant capacity (T-AOC) in plasma or erythrocyte of dairy cows were measured at 21 and 7 days prepartum, and at 7 and 21 days postpartum. Cows fed Se-yeast supplement during the last 4 weeks of gestation had higher plasma Se and lower MDA concentrations at 7 days prepartum, and at 7 and 21 days postpartum, and had higher whole blood Se and lower plasma ROS and H2O2 concentrations at 7 and 21 days postpartum compared with control cows. Se-yeast supplementation increased plasma and erythrocyte GSH-Px activities and erythrocyte GSH concentration at 7 days postpartum as compared to Se-adequate control cows. Compared with control cows, the enhanced SOD and CAT activities, increased alpha-tocopherol and GSH concentrations, and improved T-AOC in plasma at 7 and 21 days postpartum in Se yeast-supplemented cows were also observed in this study. The results indicate that feeding Se-adequate cows a Se-yeast supplement during late gestation increases plasma Se status, improves antioxidant function, and relieves effectively oxidative stress occurred in early lactation. PMID- 29594693 TI - Quality of information on the Internet-has a decade made a difference? AB - BACKGROUND: While patients accessing the Internet can be a positive step towards health literacy and self-efficacy, these resources vary in quality. AIMS: In 2007, Kulasegarah et al. assessed the information available to patients on the Internet on three common ENT procedures (tonsillectomy, septoplasty, and myringoplasty), looking at the quality of the information in terms of completeness and accuracy. This is a follow-on study to examine how this information has changed after 10 years. METHODS: Following a Google search, the top 20 webpages on each of the three ENT procedures, tonsillectomy, septoplasty, and myringoplasty, were analyzed. RESULTS: Webpages gave on average 50.6% of the critical information a patient should know prior to undergoing surgery. This is a drop from 2007 (65.5%). Over 96.8% were found to have no inaccuracies identified on the available information provided on the websites. This was slightly higher than in 2007 (94.7%). YouTube (10%) and hospital webpages (10%) were among the new subcategories that were not present in the 2007 study. CONCLUSIONS: Due to the reduced completeness of information available to patients online, it is important that health professionals direct patients to appropriate websites if they wish to do their own research. PMID- 29594694 TI - Surface enhanced Raman detection of the colon cancer biomarker cytidine by using magnetized nanoparticles of the type Fe3O4/Au/Ag. AB - Cytidine is regarded as an early marker of colon cancer. The authors describe a surface enhanced Raman scattering (SERS) technique to detect trace levels of cytidine in urine. The Raman band at 784 cm-1 can be acquired best. Compared to earlier methods, an improvement in detection sensitivity by a factor of 6.2 * 105 is achieved by using a magnetically induced method in which cytidine is captured in the vicinity of the SERS hot spots of the type Fe3O4/Au/Ag. Cytidine can be quantified at 1 nM levels by this method which is simple and reliable. Graphical Abstract Clusters consisting of magnetite (Fe3O4) nanoparticles, gold nanoparticles and silver nanoparticles were prepared and used in a SERS based method for detection of cytidine in urine by using magnetic improvement. The lowest detectable concentration of cytidine are at the nM level. PMID- 29594695 TI - Magnetic nanoparticle based solid-phase extraction of heavy metal ions: A review on recent advances. AB - This review (with 151 refs) focuses on recent progress that has been made in magnetic nanoparticle-based solid phase extraction (SPE), pre-concentration and speciation of heavy metal ions. In addition, it discusses applications to complex real samples such as environmental, food, and biological matrices. The introduction addresses current obstacles and limitations associated with established SPE approaches and discusses the present state of the art in different formats of off-line and on-line SPE. The next section covers magnetized inorganic nanomaterials for use in SPE, with subsections on magnetic silica, magnetic alumina and titania, and on magnetic layered double oxides.

We then discuss the progress made in SPE based on the use of magnetized organic polymers (mainly non-imprinted and ion imprinted polymer). This is followed by shorter sections on the use of magnetized metal organic frameworks, magnetized ionic liquids and magnetized biosorbents. All sections include discussions of the nanomaterials in terms of selectivity, sorption capacity, mechanisms of sorption and common routes for material synthesis. A concluding section addresses actual challenges and discusses perspective routes towards further improvements.

AB - The authors describe an electrochemical sensor for the determination of 5 hydroxytryptamine (5-HT; serotonin). It is based on the use of platinum nanoparticles (PtNPs) coated with molecularly imprinted silica (MIS). The MIS coated PtNPs were prepared from 5-HT, PtNPs, phenyltrimethoxysilane and tetraethoxysilane that act as template, support, functional monomer and cross linker, respectively. The MIS-coated PtNPs were characterized by Fourier transfer infrared spectroscopy and transmission electron microscopy. The MIS-coated PtNPs were drop-cast onto a glassy carbon electrode (GCE) to obtain an electrochemical sensor for 5-HT which exhibited fast response and high recognition ability for 5 HT. The imprinting factor of this electrode for 5-HT is 4.12, which is higher than that for its analogs. Under optimized conditions and at a typical working potential of 0.29 V (vs. Hg/Hg2Cl2), the electrode has a linear response in the 0.05-80 MUM 5-HT concentration range and a 0.02 MUM detection limit. The electrode was successfully applied to the determination of 5-HT in human serum samples. Graphical Abstract Molecularly imprinted silica-coated platinum nanoparticles were prepared using surface imprinting technique. A glassy carbon electrode modified with the surface imprinted material exhibits fast response in detecting 5-hydroxytryptamine, a low detection limit, good selectivity, reproducibility and stability.

AB - The authors report that sulfide ions are capable of inhibiting the peroxidase like activity of copper nanoclusters (CuNCs). The catalytic activity of CuNCs toward the oxidation of the chromogenic substrate 3,3',5,5'-tetramethylbenzidine by H2O2 is remarkably decreased in the presence of sulfide. Based on this finding, a colorimetric assay was developed for the rapid determination of sulfide. Best operated at a wavelength of 652 nm, it has a 0.5 MUM detection limit. The method is highly selective and has been successfully applied to the quantification of sulfide in environmental water samples. Graphical abstract The catalytic activity of CuNCs toward the oxidation of 3,3',5,5' tetramethylbenzidine by H2O2 is remarkably decreased in the presence of sulfide ions. This finding has been applied to design a method for colorimetric quantification of sulfide ions in environmental samples.

AB - The authors describe a colorimetric method for the sensitive and selective detection of Pb(II). It is based on the use exonuclease I (Exo I), a Pb(II) binding aptamer bound to gold nanoparticles (AuNPs), and a DNA strand that complementary to the aptamer. In the absence of Pb(II), the dsDNA on the AuNPs prevents aggregation of the AuNPs in the presence of NaCl. In the presence of Pb(II), however, the aptamer binds Pb(II) and complementary strand is released and digested by Exo I. As a result, the solution of AuNPs undergoes a color change from red to purple if salt is added to the sample. The assay is selective for Pb(II) and has a limit of detection as low as 2.4 nM. It was successfully applied to the determination of Pb(II) in spiked tap water.

AB - The authors describe a novel water-soluble, stable, biocompatible, and highly fluorescent probe consisting of iron quantum clusters incorporated into human adult hemoglobin (Hb-FeQCs). The Hb-FeQCs were characterized by various spectroscopic techniques. The probe displays strong absorption and yellow fluorescence with a peak centered at 567 nm (photo-excited at 460 nm). The Hb FeQCs show excellent photostability over a wide range of pH values (5-12), even in the presence of high electrolyte concentrations. A colorimetric and a fluorometric method were worked out for the quantitation Zn(II) and cysteine in aqueous solution. Zinc ions induce a visible color change from brown to yellow. The sensitivity of Hb-FeQCs towards other metal ions was negligible, with the exception of Co2+ and Cu2+, which caused a modest interference. The Hb-FeQCs were exploited in a sensitive and selective turn-on fluorescence assay for Zn2+. It is also found that cysteine quenches the fluorescence of the Hb-FeQCs/Zn(II) complex. Under the optimized conditions, the probe has a linear response in the 0.04 to 2.2 MUM Zn(II) concentration range, with a 48 nM detection limit. Response to cysteine is linear in the 1-60 MUM concentration range, with a 0.25 MUM limit of detection. This fluorescent probe undergoes fluorescent emission intensity enhancement upon binding to zinc ions in living normal human fibroblast cells under visible lamp. The cellular imaging capability and very low cytotoxicity of this soluble iron quantum clusters can be potentially extended as an exciting sub-nanoplatform with promising biomaterial applications. Graphical abstract Schematic of yellow-emitting iron quantum clusters in hemoglobin matrix (Hb-FeQCs) were characterized and successfully applied for sensing zinc(II) and cysteine.

AB - A composite consisting of carbon quantum dots (CQDs) and overoxidized poly(2 aminopyridine) (PAPox) was deposited on a glassy carbon electrode (GCE) through electrochemical polymerization and electrochemical oxidation. The modified GCE was used for the simultaneous determination of guanine and adenine. Electrochemical responses to guanine and adenine were investigated by cyclic voltammetry and differential pulse voltammetry. Owing to the synergistic effect of CQDs and PAPox, two oxidation peaks can be observed, with peaks at 0.81 and 1.13 V (vs. SCE) for guanine and adenine, respectively. The current at the respective peaks has a linear dependence on the concentrations of guanine in the range from 1.0 to 65 MUM, and of adenine in the range from 2.0 to 70 MUM. The respective detection limits are 0.51 and 0.39 MUM (at an S/N ratio of 3). The modified GCE is selective, reproducible and stable. Graphical abstract Schematic of the preparation of a glassy carbon electrode modified with carbon quantum dots and overoxidized poly(2-aminopyridine (CQD/PAPox/GCE), and its application for the simultaneous determination of guanine and adenine.

AB - The goal of this study was to examine, in a nationally representative sample, relationships between various sexual initiation patterns, subsequent sexual partnerships, and related health outcomes from adolescence through early adulthood. Data were from a subset of 6587 respondents from the National Longitudinal Study of Adolescent to Adult Health. Bivariate analyses and adjusted logistic and ordinary least squares regression models were used to determine associations between membership in three sexual initiation classes, lifetime sexual partner counts, and multiple health outcomes, including lifetime sexually transmitted infection or disease (STI/STD) diagnosis, lifetime unintended pregnancy, and romantic relationship quality. Broadly, having fewer lifetime sexual partners was associated with lower odds of STI/STD diagnosis and unintended pregnancy, and better relationship quality; however, findings also indicated both within and between sexual initiation class differences in the relationship between lifetime sexual partners and all three health outcomes. In particular, results showed little variation in health outcomes by sexual partnering among those who postponed sexual activity, but members of the class characterized by early and atypical sexual initiation patterns who had fewer lifetime partners exhibited better health outcomes than most other initiation groups. These results show that while both sexual initiation and partnering patterns add important information for understanding sexual health from adolescence to early adulthood, partnering may be more relevant to these sexual health outcomes. Findings indicate a need for more comprehensive sexuality education focused on sexual risk reduction and promotion of relationship skills among adolescents and adults.

AB - Body dissatisfaction plays an important role in the development of psychiatric problems such as eating disorders as well as gender dysphoria (GD). Cross-sex hormonal treatment (CHT) alleviates the dissatisfaction by making various changes in the body. We examined the alteration of body uneasiness, eating attitudes and behaviors, and psychological symptoms longitudinally in Turkish participants with female-to-male gender dysphoria (FtM GD) after CHT. Thirty-seven participants with FtM GD and 40 female controls were asked to complete the Body Uneasiness Test to explore different areas of body-related psychopathology, the Eating Attitudes Test to assess eating disturbances, and the Symptom Checklist-90 Revised to measure psychological state, both before CHT and after 6 months of CHT administration. The baseline mean body weight, BMI scores, body uneasiness scores, and general psychopathological symptoms of participants with FtM GD were significantly higher than female controls, whereas baseline eating attitudes and behaviors were not significantly different. Over time, FtM GD participants' mean body weight and BMI scores increased, body uneasiness and general psychopathological symptoms decreased, and eating attitudes and behaviors had not changed at 24th weeks following CHT administration compared to baseline. CHT may have a positive impact on body uneasiness and general psychopathological symptoms in participants with FtM GD. However, CHT does not have an impact on eating attitudes and behaviors.

AB - Patients presenting with spontaneous, non-aneurysmal subarachnoid hemorrhage (SAH) achieve better outcomes compared to patients with aneurysmal SAH. Nevertheless, some patients develop shunt-dependent hydrocephalus during treatment course. We therefore analyzed our neurovascular database to identify factors determining shunt dependency after non-aneurysmal SAH. From 2006 to 2016, 131 patients suffering from spontaneous, non-aneurysmal SAH were admitted to our department. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non perimesencephalic SAH (npSAH). Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months and stratified into favorable (mRS 0-2) versus unfavorable (mRS 3-6). A multivariate analysis was performed to identify predictors of shunt dependency in patients suffering from non-aneurysmal SAH. Overall, 18 of 131 patients suffering from non-aneurysmal SAH developed shunt dependency (14%). In detail, patients with npSAH developed significantly more often shunt dependency during treatment course, when compared to patients with pSAH (p = 0.02). Furthermore, patients with acute hydrocephalus, presence of intraventricular hemorrhage, presence of clinical vasospasm, and anticoagulation medication prior SAH developed significantly more often shunt dependency, when compared to patients without (p < 0.0001). However, "acute hydrocephalus" was the only significant and independent predictor for shunt dependency in all patients with non-aneurysmal SAH in the multivariate analysis (p < 0.0001). The present study identified acute hydrocephalus with the necessity of CSF diversion as significant and independent risk factor for the development of shunt dependency during treatment course in patients suffering from non-aneurysmal SAH.

AB - Three dimensional (3D) bioprinting has been proposed as a method for fabricating tissue engineered small diameter vascular prostheses. This technique not only involves constructing the structural features to obtain a desired pattern but the morphology of the pattern may also be used to influence the behavior of seeded cells. Herein, we 3D bioprinted a gelatin hydrogel microchannel construct to promote and preserve the contractile phenotype of vascular smooth muscle cells (vSMCs), which is crucial for vasoresponsiveness. The microchanneled surface of a gelatin hydrogel facilitated vSMC attachment and an elongated alignment along the microchannel direction. The cells displayed distinct F-actin anisotropy in the direction of the channel. The vSMC contractile phenotype was confirmed by the positive detection of contractile marker gene proteins (alpha-smooth muscle actin (alpha-SMA) and smooth muscle-myosin heavy chain (SM-MHC)). Having demonstrated the effectiveness of the hydrogel channels bioprinted on a film, the bioprinting was applied radially to the surface of a 3D tubular construct by integrating a rotating mandrel into the 3D bioprinter. The hydrogel microchannels printed on the 3D tubular vascular construct also orientated the vSMCs and strongly promoted the contractile phenotype. Together, our study demonstrated that microchannels bioprinted using a transglutaminase crosslinked gelatin hydrogel, could successfully promote and preserve vSMC contractile phenotype. Furthermore, the hydrogel bioink could be retained on the surface of a rotating polymer tube to print radial cell guiding channels onto a vascular graft construct. PMID- 29594705 TI - Gold nanoparticle-based colorimetric ELISA for quantification of ractopamine. AB - The work describes a gold nanoparticle-based colorimetric enzyme-linked immunosorbent assay (ELISA) for ractopamine. The ELISA is based on an indirect competitive approach. In the presence of ractopamine, gold(III) ions are oxidized by H2O2 to form red AuNPs. On the other hand, the AuNP in solution are purple blue due to aggregation if the sample does not contain ractopamine. The absorption, best measured at 560 nm, increases linearly in the 2 to 512 ng.mL-1 ractopamine concentration range, and the detection limit is as low as 0.35 ng.mL 1 in urine. Ractopamine can also be detected visually, even in the presence of other beta-agonists and antibiotics. The results obtained by this method are consistent with those obtained by LC-MS/MS as demonstrated by analysis of sheep urine. The ELISA method described here is inexpensive, easy-to-use, and suitable for rapid screening of ractopamine in animal samples. Graphical abstract Schematic presentation of a colorimetric indirect competitive immunoassay for ractopamine. It is based on the use of catalase labeled IgG and the measurement of the absorption of red gold nanoparticles (AuNPs) that are generated by the reaction of gold ions with H2O2. In the absence of ractopamine, the solution becomes blue.

AB - A visible-light driven photoelectrochemical (PEC) aptasensor is described that is capable of detecting chloramphenicol (CAP). It is based on the use of a TiO2 based nanorod array (NRA) sensitized with Eu(III)-doped CdS quantum dots. The NRA absorbs visible-light and while strongly depressing the recombination of photogenerated charges, thereby improving photo-to-current conversion efficiency. The introduction of Eu(III) ions promotes the charge transformation and utilization, and this results in a further increase of photocurrent. The NRA was employed as the photoactive material for the fabrication of a PEC aptasensor. CAP binding aptamers were immobilized on a fluorine-doped tin oxide (FTO) electrode that was modified with the NRA. The aptasensor was applied to the determination of CAP by monitoring the decrease in photocurrent (at a typical voltage of 0 V) that is caused by the formation of the aptamer-CAP complex. Under optimal conditions, the response is linear in the 1.0 pM to 3.0 nM CAP concentration range, with a detection limit of 0.36 pM (at S/N = 3). The method was applied to the determination of CAP in spiked milk samples where it gave satisfactory results.

AB - A paper-based chemiluminescence (CL) immunodevice is described for sensitive determination of the carcinoembryonic antigen (CEA). Capture antibody (Ab1) was first immobilized on the paper-based chip after plasma treatment of the paper surface. Next, carbon nanospheres functionalized with horse radish peroxidase (HRP) were attached as a signal antibody label. Strongly enhanced CL was achieved from the HRP catalyzed luminol/H2O2 CL system when using a sandwich immunoassay format. CEA can be quantified with a lower detection limit of 3 pg.mL-1. The method displays an almost 10-fold increased sensitivity in comparison to a commercial Ab2-HRP based kit. Conceivably, this sensitive method may also be extended by designing sensitive assays for other biomarkers of interest in point of-care diagnostics.

PMID- 29594708 TI - Endoscopic ultrasound-guided fine-needle aspiration of enlarged adrenals in patients with pyrexia of unknown origin: A single-center experience of 52 cases. AB - BACKGROUND: Fine-needle aspiration (FNA) of adrenals is needed in patients with pyrexia of unknown origin (PUO) and adrenal enlargement in absence of other diagnostic clues. Adrenals are easily accessible by endoscopic ultrasound (EUS) due to proximity; however, there is no systemic study available on FNA of adrenals in patients with PUO. The aim of this study was to evaluate the diagnostic yield and safety of EUS-FNA of enlarged adrenal in patients with PUO. METHODS: Data was analyzed from October 2010 to September 2016 at a single tertiary care center in northern India. EUS-FNA of enlarged adrenals was done in 52 patients for the etiological diagnosis of PUO in whom a definitive diagnosis could not be made with other means. RESULTS: The mean age was 48+/-14 years; 36 were males and 16 were females. EUS-FNA was done from the left adrenal in 50 patients and from the right sample in 2 patients. A technical success was achieved in 100% cases. The 19-G needle was used in the majority (75%) to the presence of necrotic areas in adrenals; median numbers of passes were 2. The cytopathological diagnoses were tuberculosis (n = 36), histoplasmosis (n = 13), lymphoma (n = 2), and metastasis from undiagnosed neuroendocrine tumor of lung (n = 1). Thus, a diagnosis could be made in 52/52 (100%) patients. None of the patients had any procedure-related complications. CONCLUSIONS: EUS-FNA is a safe and effective method for evaluating etiology of PUO in patients with adrenal enlargement.

PMID- 29594711 TI - Validation and Optimization of BIANCA for the Segmentation of Extensive White Matter Hyperintensities. AB - White matter hyperintensities (WMH) are a hallmark of small vessel diseases (SVD). Yet, no automated segmentation method is readily and widely used, especially in patients with extensive WMH where lesions are close to the cerebral cortex. BIANCA (Brain Intensity AbNormality Classification Algorithm) is a new fully automated, supervised method for WMH segmentation. In this study, we optimized and compared BIANCA against a reference method with manual editing in a cohort of patients with extensive WMH. This was achieved in two datasets: a clinical protocol with 90 patients having 2-dimensional FLAIR and an advanced protocol with 66 patients having 3-dimensional FLAIR. We first determined simultaneously which input modalities (FLAIR alone or FLAIR + T1) and which training sets were better compared to the reference. Three strategies for the selection of the threshold that is applied to the probabilistic output of BIANCA were then evaluated: chosen at the group level, based on Fazekas score or determined individually. Accuracy of the segmentation was assessed through measures of spatial agreement and volumetric correspondence with respect to reference segmentation. Based on all our tests, we identified multimodal inputs (FLAIR + T1), mixed WMH load training set and individual threshold selection as the best conditions to automatically segment WMH in our cohort. A median Dice similarity index of 0.80 (0.80) and an intraclass correlation coefficient of 0.97 (0.98) were obtained for the clinical (advanced) protocol. However, Bland-Altman plots identified a difference with the reference method that was linearly related to the total burden of WMH. Our results suggest that BIANCA is a reliable and fast segmentation method to extract masks of WMH in patients with extensive lesions.

AB - The work describes a fluorescence-based study for mapping the highest affinity truncated aptamer from the full length sequence and its integration in a graphene oxide platform for the detection of Salmonella enteriditis. To identify the best truncated sequence, molecular beacons and a displacement assay design are applied. In the fluorescence displacement assay, the truncated aptamer was hybridized with fluorescein and quencher-labeled complementary sequences to form a fluorescence/quencher pair. In the presence of S. enteritidis, the aptamer dissociates from the complementary labeled oligonucleotides and thus, the fluorescein/quencher pair becomes physically separated. This leads to an increase in fluorescence intensity. One of the truncated aptamers identified has a 2-fold lower dissociation constant (3.2 nM) compared to its full length aptamer (6.3 nM). The truncated aptamer selected in this process was used to develop a fluorometric graphene oxide (GO) based assay. If fluorescein-labeled aptamer is adsorbed on GO via pi stacking interaction, fluorescence is quenched. However, in the presence of target (S. enteriditis), the labeled aptamers is released from surface to form a stable complex with the bacteria and fluorescence is restored, depending on the quantity of bacteria being present. The resulting assay has an unsurpassed detection limit of 25 cfu.mL-1 in the best case. The cross reactivity to Salmonella typhimurium, Staphylococcus aureus and Escherichia coli is negligible. The assay was applied to analyze doped milk samples for and gave good recovery. Thus, we believe that the truncated aptamer/graphene oxide platform is a potential tool for the detection of S. Enteritidis. Graphical abstract Fluorescently labelled aptamer against Salmonella enteritidis was adsorbed on the surface of graphene oxide by pi-stacking interaction. This results in quenching of the fluorescence of the label. Addition of Salmonella enteritidis restores fluorescence, and this effect is used for quantification of this food-borne pathogen.

AB - Europium(III)-doped carbon dots (Eu-CDs) were prepared from citric acid and europium nitrate via a one-pot pyrolytic method. The Eu-CDs emit intense blue fluorescence (with excitation/emission peaks at 365/465 nm), are water soluble and biocompatible. On addition of 2,6-dipicolinic acid (DPA; an anthrax biomarker), ligand-to-ion energy transfer occurs from DPA to Eu(III) which has a red emission peaking at 615 nm. This results in an increase of the intensity of the red fluorescence. DPA can be detected by the ratio of fluorescence intensities at 616 and 475 nm. The method has an analytical range that extends from 5 to 700 nmol.L-1, with a 5 nmol.L-1 detection limit. The Eu-CDs also were incorporated into a test paper for visual detection of DPA with a portable UV lamp and a smartphone. In this case, the detection limit is 1 MUmol.L-1. The Eu CDs internalize well into HeLa cells, and this paves the way to bioimaging.

AB - The authors report that graphene oxide nanoribbons exert a strong catalytic effect on the reduction of HAuCl4 by H2O2 to form gold nanoparticles which display nanoplasmonic surface enhanced Raman scattering (SERS) activity, Rayleigh scattering and absorption. If an aptamer against Pb(II) is present in solution, it will bind to the graphene oxide nanoribbons and thereby inhibit their catalytic activity. Upon addition of Pb(II), it will bind to the aptamer to form stable complexes and release free graphene oxide nanoribbon. These cause the surface enhanced Raman scattering intensity at 1615 cm-1 to increase in the presence of the molecular probe Victoria Blue B. The SERS signal increases linearly in the 0.002-0.075 MUmol.L-1 Pb(II) concentration range, and the detection limit is 0.7 nmol.L-1. Toner samples were spiked and then analyzed for Pb(II) by this method. Relative standard deviations are between 6.2% and 12.2%, and recoveries range from of 86.7%-106.7%.

AB - A dual-channel ratiometric nanoprobe is described for detection and imaging of microRNA. It was prepared from MoS2 quantum dots (QDs; with blue emission and excitation/emission peaks at 310/398 nm) which acts as both the gene carrier and as a donor in fluorescence resonance energy transfer (FRET). Molecular beacons containing loops for molecular recognition of microRNA and labeled with carboxyfluorescein (FAM) were covalently attached to the MoS2 QDs and serve as the FRET acceptor. In the absence of microRNA, the nanoprobe exhibits low FRET efficiency due to the close distance between the FAM tag and the QDs. Hybridization with microRNA enlarges the distance between QD and beacon. This results in an enhancement of the FRET efficiency of the nanoprobe. The ratio of green and blue fluorescence (I520/I398) increases linearly in the 5 to 150 nM microRNA concentration range in both aqueous solution and diluted artificial cerebrospinal fluid. The limit of detection (LOD) is as low as 0.38 nM and 0.52 nM, respectively. Other features of this nanoprobe include (a) excellent resistance to nuclease-induced false positive signals and (b) the option to use it for distinguishing different cell lines by in-situ imaging of intracellular microRNAs.

AB - A new water soluble fluorescent coronene probe (CTCA) was synthesized and is shown to display strong fluorescence (with excitation/emission maxima at 313/450 nm) in aqueous solution. Dopamine was oxidized under air to form polydopamine (PDA) which quenches the fluorescence of CTCA. The enzyme acetylcholinesterase (AChE) is known catalyze the hydrolysis of acetylthiocholine to produce thiocholine. Thiocholine inhibits the polymerization of DA, and this leads to recovery in CTCA fluorescence. These findings form the basis for a new method for detection of AChE activity. The assay has a detection limit as low as 0.05 mU.mL 1 of AChE. It is highly selective, and other enzymes do no noticeably interfere. It was applied to the determination of AChE activity in (spiked) human serum, and of AChE inhibitors in (spiked) lake water samples. Graphical abstract Controlled synthesis of polydopamine for the highly sensitive and selective sensing of AChE activity is reported for the first time.

AB - A method is described for the rapid fluorometric determination of dopamine (DA) by using molybdenum disulfide quantum dots (MoS2 QDs) that were fabricated via an ammonium hydroxide etching method. The probe has a fluorescence (with excitation/emission peaks at 267/380 nm) that is quenched by DA with high selectivity over various interferences. This is attributed to a reaction that occurs between DA and the molybdate ions in pH 9 solutions of MoS2 QDs. The formation of organic molybdate complexes and of dopamine-quinone results in strong quenching of the fluorescence of the QDs which is due to both electron transfer and an inner filter effect. Under the optimum conditions, the assay works in the 0.1-100 MUM DA concentration range, with two linear ranges and a 10 nM detection limit. The method was applied to the determination of DA in spiked artificial urine samples, where it gave recoveries ranging from 97.6 to 102.2%, demonstrating that the method a promising tool for rapid and selective detection of DA. Graphical abstract MoS2 QDs are facilely synthesized via the etching effect of ammonium hydroxide for highly selective fluorometric detection of dopamine.

AB - PURPOSE OF REVIEW: Historically, anxiety disorders have not been considered as important determinants of suicide, but in the last years, many works have challenged this assumption. Here, we will review the available evidence on the relationship between suicide and anxiety disorders (e.g., obsessive-compulsive disorder, post-traumatic stress disorder, generalized anxiety disorder, panic disorder, and body dysmorphic disorder), with special emphasis on findings published in the last years. RECENT FINDINGS: Overall, anxiety disorders increase the risk of suicide. Specifically, 16% of patients with social anxiety disorder reported suicidal ideation in the previous month, and 18% of them had a history of suicide attempts. Similarly, in patients with panic disorder, suicidal ideation prevalence ranged between 17 and 32%, and 33% of them had a history of suicide attempts. Generalized anxiety disorder (GAD) was the most frequent anxiety disorder in completed suicides (present in 3% of people who committed suicide) and also subthreshold GAD was clearly linked to suicide ideation. Post traumatic stress disorder was positively associated with suicidal ideation, and in patients with obsessive-compulsive disorder, suicide ideation rates ranged from 10 to 53% and suicide attempts from 1 to 46%. Body dysmorphic disorders presented a suicide ideation prevalence of about 80%. Suicide risk is increased in subjects with anxiety disorder. This risk is higher in the presence of comorbidities, but it is not clear whether it is independent from such comorbidities in some disorders.

AB - ATP-sensitive potassium channels (KATP) are energy sensors on the plasma membrane. By sensing the intracellular ADP/ATP ratio of beta-cells, pancreatic KATP channels control insulin release and regulate metabolism at the whole body level. They are implicated in many metabolic disorders and diseases and are therefore important drug targets. Here, we present three structures of pancreatic KATP channels solved by cryo-electron microscopy (cryo-EM), at resolutions ranging from 4.1 to 4.5 A. These structures depict the binding site of the antidiabetic drug glibenclamide, indicate how Kir6.2 (inward-rectifying potassium channel 6.2) N-terminus participates in the coupling between the peripheral SUR1 (sulfonylurea receptor 1) subunit and the central Kir6.2 channel, reveal the binding mode of activating nucleotides, and suggest the mechanism of how Mg-ADP binding on nucleotide binding domains (NBDs) drives a conformational change of the SUR1 subunit.

AB - A platform is described for voltammetric sensing of hydrogen peroxide (H2O2). It is based on the use of nitrogen-doped graphite foam modified with Prussian Blue particles (PB/NGF). Graphite foam was synthesized by chemical vapor deposition, and doping with nitrogen was realized via dielectric barrier plasma discharge. PB particles were grown on the NGF through electrodeposition. SEM images of NGF verified the porous and interconnected structure of graphite foam, and XPS and Raman spectroscopy verified the successful doping with N. The performance of the PB/NGF electrode was characterized by CV and EIS which showed it to possess outstanding properties in terms of sensing H2O2. H2O2 was quantified in a range of 0.004 to 1.6 mM with a detection limit of 2.4 MUM. The PB/NGF electrode also is shown to be a viable substrate for loading glucose oxidase (GOx). The GOx functionalized electrode responds to glucose over the 0.2 to 20 mM concentration range at a potential of -50 mV (vs. Ag/AgCl), with a sensitivity of 27.48 mA M-1 cm-2 and a 0.1 M detection limit (at an S/N ratio of 3). The glucose sensor is selective, stable, and reproducible. The biosensor was successfully applied to the determination of glucose in spiked human serum samples, and this confirmed it practicability.

AB - Unclaimed prize information (i.e., the number of prizes still available to be won) is information commonly provided to scratch card gamblers. However, unless the number of tickets remaining to be purchased is also provided, this information is uninformative. Despite its lack of utility in assisting gamblers in choosing the most favourable type of scratch card to play, we hypothesized that unclaimed prize information would bias participants' judgments within a scratch card gambling context. In Experiment 1 (N = 201), we showed that participants are influenced by this information such that they felt more likely to win, were more excited to play, and preferred to hypothetically purchase more of the scratch card with the greatest number of unclaimed prizes. In Experiment 2 (N = 201), we attempted to ameliorate this bias by providing participants with the number of tickets remaining to be purchased and equating the payback percentages of all three games. The bias, although attenuated, still persisted in these conditions. Finally, in Experiment 3 (N = 200), we manipulated the hypothetical scratch cards such that games with the highest number of unclaimed prizes were the least favourable, and vice versa. As in Experiment 2, participants still favoured cards with greater numbers of unclaimed prizes. Possible mechanisms underlying this bias are discussed. In conclusion, across three experiments, we demonstrate that salient unclaimed prize information is capable of exerting a strong effect over judgments related to scratch card games.

AB - Children with attention-deficit/hyperactivity disorder (ADHD) experience difficulties related to emotional reactivity and regulation. The current study examines differences in the emotional reactivity and regulation of children with and without ADHD in the context of their real-life experiences of negative emotion using a novel ecologically valid methodology. Eighty-three 8-12-year-old children (46 ADHD, 38 non-ADHD) participated in the study. Children completed the negative emotion narrative recall task, a novel task whereby children provided a narrative recall of a real-life event where they experienced negative emotion. ANCOVA indicated children with ADHD recalled significantly more overall frustration and intense frustration than children without ADHD. Children with ADHD exhibiting more negative emotional reactivity while recalling negative emotions than children without ADHD. The current study suggests that children with ADHD are uniquely impacted by negative emotional experiences and represents an important step in understanding the emotional reactivity and regulation of children with ADHD.

AB - BACKGROUND/AIM: Right lobe living donor (2/3rd partial hepatectomy) model is the best way to accurately study liver regeneration process in human beings. We aimed to study the kinetics of liver regeneration after 2/3rd partial hepatectomy in donors. METHODS: Retrospective analysis of prospectively maintained volumetric recovery data in donors was performed in 23 donors, who underwent 29 contrast enhanced computed tomography within 3 months for various clinical indications. RESULTS: The absolute volumetric growth percentages were as follows: 37.60 +/- 21.74 at 1st week, 92 +/- 53.27 at 2nd week, 115.55 +/- 59.65 at 4th week, and 110.79 +/- 64.47 at 3 months. On sub-group analysis of our cohort, we found that 4.3%, 17%, 30.4%, and 39% donors attended >= 90% volumetric recovery at 1st, 2nd, 4th week, and 3 months, respectively. One patient at 4th week revealed 128% volumetric recovery. There was one more patient who exceeded original total liver volumes (TLV) (111% of TLV) at 2.5 months. The serum bilirubin and INR values peaked at postoperative day (POD) 3rd and then started showing a downward trend from POD 5th onwards. CONCLUSION: Our study is the first to document complete volumetric recovery in donors as early as 3 weeks. Two of the donors overshot their original TLV during the early regenerative phase.

AB - The authors describe a method for the fluorometric determination of methicillin resistant Staphylococcus aureus (MRSA) by exploiting target-triggered chain reactions and deoxyribonuclease I (DNase I)-aided target recycling. It is making use of a carboxy-fluorescein (FAM)-labeled single-stranded probe containing two sections. One is complementary to the 5' terminus of the target, while the 3' terminus of the other target is adsorbed on the surface of graphene oxide (GO) via pi-stacking interactions without the target (16S rRNA). This adsorption results in quenching of the fluorescence of the label and protects it from being cleaved by DNase I. However, upon addition of the target, DNA/RNA hybrids are repelled by GO. This leads to fluorescence recovery as measured at excitation/emission wavelengths of 480/514 nm due to a chain reaction that is triggered by the target. The signal is strongly amplified by using DNase I mediated target recycling. The 16S rRNA of MRSA can be detected by this method in the 1 to 30 nM concentration range, and the detection limit is 0.02 nM. The method was applied to analyze bacterial samples, and the detection limit is as low as 30 CFU . mL-1. The assay is highly sensitive and selective and in our percpetion has a large potential in diagnosis of drug-resistant bacteria.

AB - Flower Pollination Algorithm (FPA) has increasingly attracted researchers' attention in the computational intelligence field. This is due to its simplicity and efficiency in searching for global optimality of many optimization problems. However, there is a possibility to enhance its search performance further. This paper aspires to develop a new FPA variant that aims to improve the convergence rate and solution quality, which will be called modified global FPA (mgFPA). The mgFPA is designed to better utilize features of existing solutions through extracting its characteristics, and direct the exploration process towards specific search areas. Several continuous optimization problems were used to investigate the positive impact of the proposed algorithm. The eligibility of mgFPA was also validated on real optimization problems, where it trains artificial neural networks to perform pattern classification. Computational results show that the proposed algorithm provides satisfactory performance in terms of finding better solutions compared to six state-of-the-art optimization algorithms that had been used for benchmarking.

AB - The authors describe a fluorometric strategy for the detection of pathogenic bacteria with ultrasensitivity and high specificity. This strategy relies on the combination of target-modulated photoinduced electron transfer (PET) between G quadruplex DNAzyme and DNA (labeled with silver nanoclusters) along with hairpin probe-based circular exponential amplification. The reaction system involves three hairpin probes (H1, H2 and H3). Probe H1 contains an aptamer against S. Typhimurium and the recognition sequence for nicking endonuclease. It is used to recognize S. Typhimurium and participates in polymerase-catalyzed target recycle amplification and secondary-target recycle amplification. Probe H2 contains an aptamer against hemin and is used to form the G-quadruplex DNAzyme in the presence of hemin and potassium ion. It acts as the electron acceptor and quenches the fluorescence of the labeled DNA. Fluorescence is best measured at excitation/emission wavelengths of 567/650 nm. Probe H3 contains the template sequence for the synthesis of AgNCs and the H2-annealing sequence. Both H2 and H3 are utilized to perform a strand displacement reaction and to achieve PET between G-quadruplex DNAzyme and DNA/AgNCs. To the best of our knowledge, this is the first example of a PET between G-quadruplex DNAzyme and DNA/AgNCs coupled with circular exponential amplification. The assay has an ultra-low detection limit 8 cfu.mL-1 of S. Typhimurium. The assay is rapid, accurate, inexpensive and simple. Hence, the strategy may represent a useful platform for ultrasensitive and highly specific detection of pathogenic bacteria as encountered in food analysis and clinical diagnosis. Graphical abstract The reaction system includes three hairpin probes (H1, H2 and H3), primer probe (P), Phi 29 DNA ploymerase (Phi 29) and nicking endonuclease Nt.AlwI (Nt.AlwI). Phi 29 and Nt.AlwI -assisted signal amplification leads to the recycling of target and produces numerous single stranded-DNAs (S). Strand displacement amplification leads to photoinduced electron transfer (PET) between G-quadruplex DNAzyme and DNA/AgNCs. HAP-based circular exponential amplification of PET results in an ultrasensitive fluorometric assay.

AB - Optical sensing of temperature by measurement of the ratio of the intensities of the 700 nm emission and the 800 nm emission of Ga(III)-doped ZnO (GZO) nanoparticles (NPs) and of GZO NPs coated with a silica shell are demonstrated at 980 nm excitation. It is found that the relative sensitivity of SiO2@Yb/Tm/GZO is 6.2% K-1 at a temperature of 693 K. This is ~3.4 times higher than that of Yb/Tm/GZO NPs. Obviously, the SiO2 shell structure decreases the rate of the nonradiative decay. The decay time of the 800 nm emission of the Yb/Tm/GZO NPs (15 mol% Ga; 7 mol% Yb; 0.5 mol% Tm) displays a biexponential decay with a dominant decay time of 148 MUs and a second decay time of ~412 MUs. The lifetime of the Yb/Tm/GZO NPs at 293 K, and of the SiO2@Yb/Tm/GZO NPs are ~412 MUs. Both the Yb/Tm/GZO and SiO2@Yb/Tm/GZO can be used up to 693 K. These results indicate that the SiO2 shell on the Yb/Tm/GZO is beneficial in terms of sensitivity and resolution. Graphical abstract The enhancement the decay time and thermal sensitivity in the SiO2@Yb/Tm/GZO shell@core structure have been studied compared to the Ga(III)-doped Yb/Tm-doped ZnO (Yb/Tm/GZO). The SiO2@Yb/Tm/GZO have good thermal accuracy up to 693 degrees C. PMID- 29594729 TI - A nanocomposite consisting of MIL-101(Cr) and functionalized magnetite nanoparticles for extraction and determination of selenium(IV) and selenium(VI). AB - A metal-organic framework nanocomposite was synthesized and applied to speciation analysis of Se(IV) and Se(VI). The sorbent is composed of MIL-101(Cr) and magnetite nanoparticles modified with dithiocarbamate. It is capably of selectively extracting Se(IV) at pH = 1.85, while Se(VI) remains in solution. The total amount of selenium can then be determined by reducing Se(VI) to Se(IV) and also extracting it. The extraction parameters were optimized by employing design of-experiments methodology. Selenium was then quantified by electrothermal AAS. Figures of merit include (a) a 10 ng.L-1 limit of detection, (b) a linear response in the 30 ng.L-1 to 10 MUg.L-1 concentration range, and (a) a relative standard deviation of <11.5% for Se(IV). The method was validated by analyzing certified reference materials (water and tomato leaves). It was also applied to the speciation analysis of Se(IV) and Se(VI) in (spiked) water samples and of total selenium in agricultural samples. Graphical abstract Schematic of the synthesis of a metal-organic framework nanocomposite for speciation analysis of Se(IV) and Se(VI). The sorbent is composed of MIL-101(Cr) and magnetite nanoparticles modified with dithiocarbamate. Selenium can be quantified by electrothermal AAS with a 10 ng L-1 detection limit. PMID- 29594730 TI - Fluorometric determination of nucleic acids based on the use of polydopamine nanotubes and target-induced strand displacement amplification. AB - The authors describe a fluorometric method for the quantitation of nucleic acids by combining (a) cycled strand displacement amplification, (b) the unique features of the DNA probe SYBR Green, and (c) polydopamine nanotubes. SYBR Green undergoes strong fluorescence enhancement upon intercalation into double-stranded DNA (dsDNA). The polydopamine nanotubes selectively adsorb single-stranded DNA (ssDNA) and molecular beacons. In the absence of target DNA, the molecular beacon, primer and SYBR Green are adsorbed on the surface of polydopamine nanotubes. This results in quenching of the fluorescence of SYBR Green, typically measured at excitation/emission wavelengths of 488/518 nm. Upon addition of analyte (target DNA) and polymerase, the stem of the molecular beacon is opened so that it can bind to the primer. This triggers target strand displacement polymerization, during which dsDNA is synthesized. The hybridized target is then displaced due to the strand displacement activity of the polymerase. The displaced target hybridizes with another molecular beacon. This triggers the next round of polymerization. Consequently, a large amount of dsDNA is formed which is detected by addition of SYBR Green. Thus, sensitive and selective fluorometric detection is realized. The fluorescent sensing strategy shows very good analytical performances towards DNA detection, such as a wide linear range from 0.05 to 25 nM with a low limit of detection of 20 pM. Graphical abstract Schematic of a fluorometric strategy for highly sensitive and selective determination of nucleic acids by combining strand displacement amplification and the unique features of SYBR Green I (SG) and polydopamine nanotubes. PMID- 29594731 TI - Carbon quantum dot-based fluorometric nitrite assay by exploiting the oxidation of iron(II) to iron(III). AB - The authors describe a simple and economical fluorescence method for the determination of nitrite by utilizing the fact that nitrite possesses strong oxidation in acidic solution and is capable to transform iron(II) into iron(III) ions. The latter quenches the fluorescence of carbon quantum dots (CQDs) based on the fluorescence static and dynamic quenching effect. The optimum reaction conditions and other analytical parameters are investigated to enhance the sensitivity of the method. At the excitation wavelength of 360 nm, this probe has a linear response in the 10 to 400 MUM nitrite concentration range, with a correlation coefficient of R2 = 0.9958 (n = 3) and a detection limit of 0.48 MUM. This method was successfully applied to the determination of nitrite in three different sausage samples and gave recoveries in the range between 101.8 to 103.0%, demonstrating the accuracy, reliability and potential application of this assay for monitoring nitrite. Graphical Abstract The carbon quantum dot/iron(II) ions system was used for the fluorometric detection of nitrite in food and environmental water. This probe exploits the oxidizing property of nitrite in acidic solution. Iron(II) is oxidized to iron(III) which exerts a strong fluorescence quenching effect.

AB - To investigate the effects of Lycium barbarum polysaccharide (LBP) on pathological symptoms and behavioral deficits in a Methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-induced Parkinson's disease (PD) mouse model. The therapeutic effects of LBP were monitored with an Open field test, a Rotarod test and a Morris water maze test. We also investigated the mechanisms with qRT-PCR and Western blotting analyses. After a relatively short-term LBP treatment, the total distance and walking time of PD mice significantly increased. The staying duration on the rod of PD mice increased in the Rotarod test. LBP can up-regulate levels of SOD2, CAT and GPX1 and inhibit the abnormal aggregation of alpha synuclein induced by MPTP. LBP treatment can also up-regulate the phosphorylation of AKT and mTOR, and may play its protective role by activating the PTEN/AKT/mTOR signaling axis. These results suggest that LBP can effectively alleviate the degeneration in the nigrostriatal system induced by MPTP treatment. It may be a potential candidate for the treatment of Parkinson's disease. PMID- 29594733 TI - Fast evaluation of protein dynamics from deficient 15N relaxation data. AB - Simple and convenient method of protein dynamics evaluation from the insufficient experimental 15N relaxation data is presented basing on the ratios, products, and differences of longitudinal and transverse 15N relaxation rates obtained at a single magnetic field. Firstly, the proposed approach allows evaluating overall tumbling correlation time (nanosecond time scale). Next, local parameters of the model-free approach characterizing local mobility of backbone amide N-H vectors on two different time scales, S2 and R ex , can be elucidated. The generalized order parameter, S2, describes motions on the time scale faster than the overall tumbling correlation time (pico- to nanoseconds), while the chemical exchange term, R ex , identifies processes slower than the overall tumbling correlation time (micro- to milliseconds). Advantages and disadvantages of different methods of data handling are thoroughly discussed. PMID- 29594734 TI - Voltammetric determination of attomolar levels of a sequence derived from the genom of hepatitis B virus by using molecular beacon mediated circular strand displacement and rolling circle amplification. AB - The authors describe an electrochemical method for the determination of the single-stranded DNA (ssDNA) oligonucleotide with a sequence derived from the genom of hepatitis B virus (HBV). It is making use of circular strand displacement (CSD) and rolling circle amplification (RCA) strategies mediated by a molecular beacon (MB). This ssDNA hybridizes with the loop portion of the MB immobilized on the surface of a gold electrode, while primer DNA also hybridizes with the rest of partial DNA sequences of MB. This triggers the MB-mediated CSD. The RCA is then initiated to produce a long DNA strand with multiple tandem repeat sequences, and this results in a significant increase of the differential pulse voltammetric response of the electrochemical probe Methylene Blue at a rather low working potential of -0.24 V (vs. Ag/AgCl). Under optimal experimental conditions, the assay displays an ultrahigh sensitivity (with a 2.6 aM detection limit) and excellent selectivity. Response is linear in the 10 to 700 aM DNA concentration range. Graphical abstract Schematic of a voltammetric method for the determination of attomolar levels of target DNA. It is based on molecular beacon mediated circular strand displacement and rolling circle amplification strategies. Under optimal experimental conditions, the assay displays an ultrahigh sensitivity with a 2.6 aM detection limit and excellent selectivity. PMID- 29594735 TI - Polydopamine nanodots are viable probes for fluorometric determination of the activity of alkaline phosphatase via the in situ regulation of a redox reaction triggered by the enzyme. AB - The authors describe an environmentally friendly and fast (~14 min) method for the synthesis of homogeneously distributed fluorescent polydopamine nanodots (PDA NDs) using KMnO4 as the oxidant. Alkaline phosphatase (ALP) catalyzes the hydrolysis of ascorbic acid 2-phosphate to release free ascorbic acid which undergoes an in-situ redox reaction with KMnO4. Depending on the activity of ALP, more or less KMnO4 is consumed, and this affects the formation of the PDA-NDs. Based on this finding, a sensitive method was worked out to quantify the activity of ALP via real-time formation of fluorescent PDA-NDs. The fluorometric signal (best measured at excitation/emission peaks of 390/500 nm) is linear in the 1 to 50 mU.mL-1 ALP activity range, and the limit of the detection is as low as 0.94 mU.mL-1 (based on 3 sigma/m). The method was successfully applied to the determination of ALP activity in spiked human serum and in MCF-7 cell lysates. It was also applied in a method to screen for inhibitors of ALP. Graphical abstract Schematic of a fluorometric method for the determination of alkaline phosphatase (ALP) activity. The method is based on the in-situ regulation of the formation of fluorescent polydopamine nanodots (PDA-NDs) through the competition between the KMnO4-induced polymerization of dopamine and ALP-directed ascorbic acid 2 phosphate (Asc-2P) hydrolysis.

AB - This work reports on the implementation of gold nanorods (AuNRs) in headspace solvent microextraction for colorimetric determination of volatile analyte derivatives in a single drop. The exposure of AuNRs to both H2Se and elemental mercury (Hg0) results in a shift of the longitudinal plasmonic band, unlike a number of volatiles. Accordingly, a method is reported for the determination of Hg0 with potential applicability to the determination of thiomersal (sodium ethylmercurithiosalicylate). It is based on the photochemical decomposition of thiomersal into Hg(II) and subsequent exposure of AuNRs-containing microdrop to in situ generated Hg0. Colorimetric analysis of the enriched drop was carried out without dilution by means of a cuvetteless microvolume UV-vis spectrometer. Under optimal conditions, the limit of detection was 0.5 ng mL-1 (as Hg). The repeatability, expressed as relative standard deviation, was 8.4% (for n = 10). AuNRs exposed to increasing concentrations of the analyte were characterized by means of transmission electron microscopy and UV-vis spectrophotometry to ascertain the mechanism of detection. The method was finally applied to the determination of thiomersal in various pharmaceutical samples and showed quantitative recoveries. Graphical abstract Schematic illustration of a miniaturized colorimetric method based on the use of a microdrop of gold nanorods (AuNRs) for thiomersal determination in pharmaceuticals. It is based on the photochemical decomposition of thiomersal and subsequent Hg0 generation with in drop amalgamation. PMID- 29594737 TI - Glomuvenous malformations: dual PDL-Nd:YAG laser approach. AB - Glomuvenous malformations are uncommon simple vascular malformations that might be present at birth or appear during childhood that have been classically classified as a subtype of venous malformations. Sclerotherapy and surgery have been used in the past as treatments for this condition although with disappointing results in large glomangiomas. The treatment of these lesions has still not been standardized. We conducted a retrospective study of 17 patients treated with dual wavelength PDL-Nd:YAG. The majority of the patients experience a reduction of at least a 60% in their glomuvenous malformations. Treatment was well-tolerated, and adverse effects were rare. PMID- 29594738 TI - A gold nanoparticle based fluorescent probe for simultaneous recognition of single-stranded DNA and double-stranded DNA. AB - A fluorescent method is described for simultaneous recognition of single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). It is based on the quenching of the fluorescence of fluorophore labeled DNA probes by gold nanoparticles (AuNPs). To demonstrate feasibility, two DNA probes labeled with spectrally different fluorophores were designed. The first DNA probe (P1) was modified with 6 carboxyfluorescein (FAM; with green fluorescence, peaking at 518 nm), while the second (P2) was modified with carboxy-X-rhodamine (ROX; with yellow fluorescence, 610 nm). The fluorescence signals of the labels are quenched if P1 or P2 are adsorbed on AuNPs. Upon addition of ssDNA and dsDNA, hybridization occurs between P1 and ssDNA to form a dsDNA. In contrast, P2 hybridizes with dsDNA such that a triplex DNA is formed. As a result, the dsDNA and the triplex DNA, respectively, are desorbed from the surface of the AuNPs so that quenching no longer can occur and strong fluorescence can be observed. Under the optimal conditions, ssDNA and dsDNA can be detected simultaneously via the green and yellow fluorescence, respectively. The detection limits can be as low as 330 pM. In particular, the method has excellent selectivity for the target DNAs over control DNAs. Graphical abstract A gold nanoparticle based fluorescent probe for simultaneous recognition of single-stranded DNA and double-stranded DNA is developed based on the fluorescence quenching of gold nanoparticles to different fluorophore labeled DNA probes. PMID- 29594741 TI - Psychological Determinants of Attitude Toward Euthanasia: A Comparative Study of Female Nurses and Female Nonmedical Professionals. AB - Moral, legal, and psychological aspects of the legality of euthanasia are subject to debates and studies of various communities. Diagnosing attitudes toward euthanasia should involve not only determining the proportion between its supporters and opponents but also the describing of mechanisms behind the development of particular views. The aim of the present study was to determine the psychological determinants of attitudes, such as fear of death-dying, self esteem, and mood. The methods consisted of using the following questionnaires: the Glebocka-Gawor Attitudes Toward Euthanasia Inventory, the Ochsmann Fear of Death and Dying Inventory, the Dymkowski Self-Description Scale, the Adamczyk Glebocka Negative Mood Inventory, and a measure of unconscious fear of death. The study involved 49 female nurses and 43 female nonmedical professionals. The results demonstrate that the attitudes and fear of death-dying did not differentiate the two groups of participants. Although the fear of dying weakened the strength of conservative views, it also reinforced the need for informational and psychological support. A high self-esteem was a predictor of conservative attitudes, while negative mood predicted liberal attitudes. Conservative attitudes were connected to a hidden fear of death and high self-esteem, while liberal attitudes were linked to a conscious fear and a rational vision of the self, the world, and the future. PMID- 29594739 TI - The IBD and PSC Phenotypes of PSC-IBD. AB - PURPOSE OF REVIEW: To review the characteristics of IBD and PSC that occur in association, as well as their reciprocal influences on disease evolution, in adult and pediatric populations. RECENT FINDINGS: IBD co-existing with PSC is genetically and clinically distinct from IBD alone. It is frequently characterized by pancolitis, rectal sparing, and possibly backwash ileitis, as well as a threefold increased risk of colorectal dysplasia. Adults and children with colitis and PSC appear to be at increased risk of active endoscopic and histologic disease in the absence of symptoms compared to individuals without PSC. PSC occurring with Crohn's disease has been observed to be less severe than PSC co-existing with ulcerative colitis, independent of its association with small duct disease. Recent studies suggest that colectomy is associated with a decreased risk of recurrent PSC after liver transplantation, challenging the traditional teaching that PSC and IBD evolve independently. While much about the gut-liver axis in PSC-IBD remains poorly understood, the IBD associated with PSC has a unique phenotype, of which subclinical inflammation is an important component. Additional research is needed to characterize further the potentially protective role of colectomy against recurrent PSC post-liver transplantation and to investigate the influence of IBD control and/or colectomy on PSC progression. PMID- 29594740 TI - Photodynamic therapy of balloon-injured rat carotid arteries using indocyanine green. AB - Photodynamic therapy (PDT) has been used to inhibit intimal hyperplasia in injured arteries. Because of the limited tissue penetration of visible light, an endovascular light source with a guided wire is often required for effective treatment. Indocyanine green (ICG), a near-infrared (NIR) photosensitizer, has been used in PDT for cancers. An extracorporeal light source may be used for shallow tissue because of the better tissue penetration of NIR light. The aim of this study was to evaluate the effect of ICG-PDT using extracorporeal NIR light on the inhibition of intimal hyperplasia in balloon-injured carotid arteries. A balloon injury (BI) model was used to induce intimal hyperplasia of carotid artery. Sprague-Dawley rats were divided into control, BI, BI + 1 * PDT, and BI + 2 * PDT groups. The control group underwent a sham procedure. PDT was performed 7 days after BI. In the BI + 1 * PDT group, ICG was administered 1 h before light irradiation. External illumination with 780-nm light-emitting diode light at a fluence of 4 J/cm2 was applied. For the BI + 2 * PDT group, PDT was performed again at day 7, following the first PDT. Hematoxylin and eosin (H & E) staining was performed to assess vessel morphology. Arterial wall thickness was significantly larger in the BI group compared with the control group. ICG-PDT significantly reduced arterial wall thickness compared with the BI group. Repeated PDT further decreased arterial wall thickness to the level of the control group. These findings indicate a promising approach for the treatment of restenosis of carotid arteries.

AB - A nafion film containing cerium phosphate nanotubes was pasted onto a glassy carbon electrode (GCE) to obtain a sensor for hydroquinone (HQ). The morphologies and components of the coating were characterized by transmission electron microscopy, scanning electron microscopy and energy-dispersive spectroscopy. Cyclic voltammetry and differential pulse voltammetry (DPV) showed the specific surface of the electrode to be significantly increased and the electron transfer rate to be accelerated. The modified GCE was applied to the determination of hydroquinone (HQ) via DPV. The oxidation current increases linearly in the 0.23 MUM to 16 mM HQ concentration range which is as wide as five orders of magnitude. The limit of detection is 0.12 MUM (based on a signal-to-noise ratio of 3), and the sensitivity is 1.41 MUA.MUM-1 cm-2. The method was further applied to the simultaneous determination of HQ, catechol and resorcinol. The potentials for the three species are well separated (20, 134, and 572 mV vs SCE). Average recoveries from (spiked) real water samples are between 95.2 and 107.0%, with relative standard deviations of 0.9~2.7% (for n = 3) at three spiking levels. The method was validated by independent assays using HPLC. Graphical abstract ?.

AB - This paper reports on the development of an amperometric method for the determination of myo-inositol. The method involves coating of a glassy carbon electrode (GCE) with a molecularly imprinted polymer (MIP) and reduced graphene oxide (RGO) that was modified with nickel nanoparticles (NiNPs). The MIP was prepared by electropolymerization of pyrrole on the surface of the GCE in the presence of myo-inositol molecules. The construction steps of the modified electrode were monitored via cyclic voltammetry, atomic force microscopy, scanning electron microscopy and X-ray Photoelectron Spectroscopy. The results were evaluated using differential pulse voltammetry, in which hexacyanoferrate was used as an electrochemically active probe. Under optimized experimental conditions, the imprint-modified GCE has a linear response in the 1.0 * 10-10 mol L-1 to 1.0 * 10-8 mol L-1 concentration range, with a 7.6 * 10-11 mol L-1 detection limit and an electrochemical sensitivity of 4.5 MUA.cm-2 MUmol-1. The method showed improved selectivity even in the presence of molecules with similar chemical structure. The GCE modified was successfully applied to the determination of myo-inositol in sugarcane vinasse where it yielded recoveries that ranged from 95 to 102%.

AB - Colloidal gold, quantum dots and polystyrene microspheres were used as labels in three kinds of lateral flow immunochromatographic assays (ICAs) for the detection of zearalenone (ZEN) in cereal samples. The assays allow ZEN to be quantified within 20 min. The LODs are 10 MUg.L-1 of ZEN for the colloidal gold-based ICA, and 1 MUg.L-1 for both the quantum dot and polystyrene microsphere based ICAs. The respective data are 60 MUg.kg-1, 6 MUg.kg-1 and 6 MUg.kg-1, respectively, for spiked samples and cereals. Only minor cross-sensitivity occurred between ZEN and fusarium toxins, and no cross-sensitivity if found for aflatoxin B1, T-2 mycotoxin, ochratoxin A, deoxynivalenol, and fumonisin B1. LODs of the three assays are lower than the maximum limits of ZEN set by most standardization agencies.

AB - PURPOSE OF REVIEW: Universal stool banks (USBs) have emerged as a potential model for scaling access to fecal microbiota transplantation (FMT) for Clostridium difficile infection (CDI). In this review, we outline the historical barriers constraining access to FMT, the evidence on methods and outcomes of USBs, and potential future directions for expanding access. RECENT FINDINGS: Key historical barriers to FMT access include regulatory uncertainty, operational complexity of sourcing screened donor material, and logistical challenges of delivering fresh treatment preparations. USBs have demonstrated that FMT can be delivered safely at scale by centralizing donor selection, material processing, and safety monitoring. More evidence is needed to optimize USB methods, including for donor screening, material processing, and novel delivery modalities. USBs have catalyzed broad access to FMT in North America and Europe. Future directions include developing evidence regarding oral preparations, harmonizing guidelines, disseminating best practice protocols, establishing long-term safety profiles, and expanding access to geographic areas of unmet need.

AB - BACKGROUND: Obstructed defecation syndrome (ODS), most commonly found in females, can be treated by a transanal or abdominal approach with good success rate. Nevertheless, patients may experience de novo or persisting pelvic floor dysfunctions after surgery. The aim of this study was to compare the functional outcome of stapled transanal rectal resection (STARR) and ventral rectopexy (VRP) in a series of ODS patients. METHODS: Forty-nine female patients who had surgery for ODS between 2006 and 2016 were retrospectively evaluated: 28 (median age 60 years, IQR 54-69 years) had VRP and 21 (median age 58 years, IQR 51-66 years) had STARR. ODS was scored with the ODS score while the overall pelvic floor function was assessed with the three axial perineal evaluation (TAPE) score. Quality-of life was evaluated by the patient assessment of constipation quality-of-life (PAC Qol) questionnaire administered preoperatively and after 1 year of follow-up. RESULTS: The preoperative median ODS score and TAPE score were comparable in both groups. After a median follow-up of 12 months (range 12-18 months), the median ODS score was 12 (range 10-20) in the STARR group and 9 (range 3-15) in the VRP one (p = 0.02), while the median TAPE score was 70.5 (IQR 60.6-77.3) in the former and 76.8 (IQR 70.2-89.7) in the latter (p = 0.01). Postoperatively the physical domain of the PAC-QoL score had a median value of 2.74 (IQR 1.7-3.75) in the STARR group compared to 1.5 (IQR 1-2.5) in the VRP group (p = 0.03). No major complications were recorded in either group. CONCLUSIONS: VRP and STARR can improve defecation in patients with ODS with minimal complications, but the overall pelvic wellness evaluated by the TAPE score improves significantly only after VRP, suggesting a better performance of VRP than STARR when overall pelvic floor function is concerned.

AB - A disposable needle-type of hybrid electrode was prepared from a core of stainless steel needle whose surface was modified with a 3D nanoporous gold/NiCo2O4 nanowall hybrid structure for electrochemical non-enzymatic glucose detection. This hybrid electrode, best operated at 0.45 V (vs. SCE) in solutions of pH 13 has a linear response in the 0.01 to 21 mM glucose concentration range, a response time of <1 s, and a 1 MUM detection limit (at an S/N ratio of 3). The remarkable enhancement compared to the solid gold/NiCo2O4 and stainless steel/NiCo2O4 hybrid electrodes in electrochemical performance is assumed to originate from the good electrical conductivity and large surface area of the hybrid electrode, which enhance the transport of mass and charge during electrochemical reactions. This biosensor was also applied to real sample analysis with little interferences. The electrode is disposable and considered to be a promising tool for non-enzymatic sensing of glucose in a variety of practical situations. Graphical abstract Ultrathin NiCo2O4 nanowalls supported on nanoporous gold that is coated on a stainless steel needle was fabricated for sensitive non-enzymatic amperometric sensing of glucose. PMID- 29594749 TI - Signalling probe displacement electrochemical aptasensor for malignant cell surface nucleolin as a breast cancer biomarker based on gold nanoparticle decorated hydroxyapatite nanorods and silver nanoparticle labels. AB - Nucleolin is a multifunctional protein that is markedly overexpressed on the surface of most cancer cells. By taking advantage of the high affinity and specificity of the AS1411 aptamer for nucleolin, a signalling probe displacement electrochemical aptasensor was developed. The thiolated AS1411 aptamer was conjugated to hydroxyapatite nanorods (HApNRs) decorated with gold nanoparticles (AuNPs). To further increase the electrical conductivity of the interface, the ionic liquid 1-ethyl-3-methylimidazolium alanine with its high ion conductivity was placed on the electrode surface. Then, the aptamer was immobilized on the modified electrode and conjugated to signalling c-DNA tagged with AgNPs (c DNA@AgNPs). In the presence of the MCF7 target cells, the signalling probe is displaced and released from the electrode surface. This leads to a decrease in the current that is proportional to the concentration of cancer cells in the range from 10 to 106 cells mL-1, with a detection limit as low as 8 +/- 2 cells mL-1 (n = 3) (based as 3sigma/m, where sigma is the standard deviation of the blank and m is the slope of the calibration plot). This method presents a promising tool for highly sensitive and selective detection of surface nucleolin on MCF7 cancer cells. Graphical abstract HApNR-AuNP-AS1411 aptamer nanocomposite as an electrochemical sensing interface was immobilized on the gold electrode surface and conjugated to signaling c-DNA tagged with AgNPs for determination of surface nucleolin on MCF7 cancer cells. PMID- 29594750 TI - Visual detection of melamine by using a ratiometric fluorescent probe consisting of a red emitting CdTe core and a green emitting CdTe shell coated with a molecularly imprinted polymer. AB - A composite ratiometric fluorescent probe is described for visual detection of melamine (MEL) in milk samples. It is based on the use of red emitting and green emitting CdTe quantum dots, and a mesoporous molecularly imprinted polymer. The red emitting QDs are embedded in the silica microsphere to serve as a core, and the green emitting QDs are coated on the surface of the silica microsphere as a shell. A molecularly imprinted polymer (MIP) with specific recognition sites for MEL was placed on the shell. If MEL is bound by the MIP, the green fluorescence is quenched due to hydrogen bond interaction. The red emission, in contrast, remains unchanged. Quenching leads to a change in the color of fluorescence from red-green to purely red. This effect allows for visual and instrumental detection of MEL. The mesoporous structure of the MIP reduces the mass transfer resistance and enhances the accessibility of sites for MEL. Response is linear in the 50 1000 ng mL-1 MEL concentration range, and the limit of detection is 13 ng mL-1. The fluorescent probe was successfully applied to the analysis of MEL-spiked milk samples and gave recoveries between 94.1 and 98.7%, with 3.6-5.1% relative standard deviations. Graphical abstract Schematic of the preparation and detection of the composite probe. The probe was applied for the selective recognition and visual detection of melamine (MEL). PMID- 29594751 TI - Determination of the activity of telomerase in cancer cells by using BSA protected gold nanoclusters as a fluorescent probe. AB - Gold nanoclusters (AuNCs) protected with a bovine serum albumin (BSA) coating are known to emit red fluorescence (peaking at 650 nm) on photoexcitation with ultraviolet light (365 nm). On addition of Cu(II) ions, fluorescence is quenched because Cu(II) complexes certain amino acid units in the BSA chain. Fluorescence is, however, restored if pyrophosphate (PPi) is added because it will chelate Cu(II) and remove it from the BSA coating on the AuNCs. Because PPi is involved in the function of telomerase, the BSA@AuNCs loaded with Cu(II) can act as a fluorescent probe for determination of the activity of telomerase. A fluorescent assay was worked out for telomerase that is highly sensitive and has a wide linear range (10 nU to 10 fM per mL). The fluorescent probe was applied to the determination of telomerase activity in cervix carcinoma cells via imaging. It is shown that tumor cells can be well distinguished from normal cells by monitoring the differences in intracellular telomerase activity. Graphical abstract Gold nanoclusters (AuNCs) protected by bovine serum albumin (BSA) and displaying red photoluminescence were prepared as fluorescent probe for the determination of telomerase activity and used for imaging of cervix carcinoma (HeLa) cells. PMID- 29594753 TI - Next-Generation Sequencing of Hepatitis C Virus (HCV) Mixed-Genotype Infections in Anti-HCV-Negative Blood Donors. AB - The infection with more than one hepatitis C virus (HCV) genotype especially in subjects with a high risk of multiple HCV exposures has been demonstrated. The role of HCV mixed-genotype infection in viral persistence and treatment effect is not fully understood. The prevalence of such infection varies greatly depending on the technique used for genotype determination and studied population. Next generation sequencing (NGS) which is suitable for extensive analysis of complex viral populations is a method of choice for studying mixed infections. The aim of the present study was to determine the prevalence of mixed-genotype HCV infections in the Polish seronegative, HCV-RNA-positive blood donors (n = 76). Two-step PCR was used for amplification of 5'-UTR of HCV. Using pyrosequencing altogether, 381,063 reads were obtained. The raw reads were trimmed and subjected to similarity analysis against the entire unfiltered NCBI nt database. Results obtained from NGS were compared with the standard genotyping. One (1.3%) mixed genotype [3a, 2989 reads (94.8%); 1b, 164 reads (5.2%)] infection was found in a sample diagnosed as genotype 3a only by routine testing. Two samples were identified with different genotypes, compared to routine testing. In conclusion, NGS is a sensitive method for HCV genotyping. The prevalence of mixed-genotype HCV infections in blood donors is low. PMID- 29594752 TI - Analysis on the influence of forest soil characteristics on radioactive Cs infiltration and evaluation of residual radioactive Cs on surfaces. AB - We investigated the depth profiles of radioactive Cs, ignition loss, and cation exchange capacity (CEC) in five types of forest soils sampled using scraper plates. We then simulated the monitored depth profiles in a compartment model, taking ignition loss as a parameter based on experimental results showing a positive correlation between ignition loss and the CEC. The calculated values were comparable with the monitored values, though some discrepancy was observed in the middle of the soil layer. Based on decontamination data on the surface dose rate and surface contamination concentration, we newly defined a surface residual index (SRI) to evaluate the residual radioactive Cs on surfaces. The SRI value tended to gradually decrease in forests and unpaved roads and was much smaller in forests and on unpaved roads than on paved roads. The radioactive Cs was assumed to have already infiltrated underground 18 months after the nuclear power plant accident, and the sinking was assumed to be ongoing. The SRI values measured on paved roads suggested that radioactive Cs remained on the surfaces, though a gradual infiltration was observed towards the end of the monitoring term. The SRI value is thought to be effective in grasping the rough condition of residual radioactive Cs quickly at sites of decontamination activity in the field. The SRI value may be serviceable for actual contamination works after further research is done to elucidate points such as the relation between the SRI and the infiltration of radioactive Cs in various types of objects. PMID- 29594754 TI - Improvement in Gait Pattern After Knee Arthroplasty Followed by Proprioceptive Neuromuscular Facilitation Physiotherapy. AB - The aim of the study was to assess the influence of a physiotherapy program based on proprioceptive neuromuscular facilitation (PNF) on kinematic gait pattern after total knee arthroplasty. This comparative study included two groups of patients qualified for total surgical knee joint replacement due to osteoarthritis: a study group and a control group, either consisting of 28 patients of a matched age range of 55-90 years. Following surgery, 4 days after standard postoperative rehabilitation, the study patients were subjected to a 3 week-long therapist-assisted rehabilitation based on PNF principles (10 sessions of 75 min each), whereas control patients were discharged with instructions on how to exercise in the home setting. The outcome consisted of spatial-temporal gait parameters that were assessed at three time points: a day before surgery and then 1 month and 6 months after. The findings were that PNF caused substantial, sustained improvements in gait kinematics, shortening the stance phases, gait cycle duration, and double support phase and prolonging swing phase velocity, gait velocity, cadence, step length, and gait cycle length. Also, postsurgical pain was evidently less. We conclude that the individually tailored PNF rehabilitation program is superior compared to a standard recommendation of home based physiotherapy in terms of improving gait kinematic pattern as well as psychological aspects related to pain perception in patients after knee arthroplasty. PMID- 29594755 TI - Dual approach for the colorimetric determination of unamplified microRNAs by using citrate capped gold nanoparticles. AB - The authors describe a method for the colorimetric determination of unamplified microRNA. It is based on the use of citrate-capped gold nanoparticles (AuNPs) and, alternatively, a microRNA-probe hybrid or a magnetically extracted microRNA that serve as stabilizers against the salt-induced aggregation of AuNPs. The absorbance ratios A525/A625 of the reacted AuNP solutions were used to quantify the amount of microRNA. The assay works in the range of 5-25 pmol microRNA. The lower limit of detection (LOD) is 10 pmol. The performance of the method was tested by detection of microRNA-210-3p in totally extracted urinary microRNA from normal, benign, and bladder cancer subjects. The sensitivity and specificity for qualitative detection of urinary microRNA-210-3p using the assay are 74% and 88% respectively, which is consistent with real time PCR based assays. The assay was applied to the determination of specific microRNA by using its specific oligo targeter or following magnetic isolation of the desired microRNA. The method is simple, cost-efficient, has a short turn-around time and requires minimal equipment and personnel. Graphical abstract Schematic of the two detection schemes: In the first approach, matched microRNA hybridizes with its specific probe to stabilize gold nanoparticles (AuNPs) against salt induced aggregation and to leave the red color of the AuNPs unchanged. In the second one, microRNA extracted via magnetic nanoparticles (MNP) stabilizes AuNPs against aggregation. PMID- 29594757 TI - Operative time and length of stay is similar between robotic assisted and laparoscopic colon and rectal resections. AB - Robotic-assisted surgery is increasingly being utilized for colorectal surgery. Data are scarce and contradictory when outcomes are compared between robotic and laparoscopic surgery. All patients undergoing minimally invasive colorectal surgery were compared from 2011 to 2016. Outcomes between the two groups were statistically analyzed. p < 0.05 was considered statistically significant. 185 patients underwent laparoscopic resection and 70 underwent robotic resection. Demographics, ASA score, and BMI were similar between the two groups (p > 0.05). There was no statistical difference in median length of stay between laparoscopic and robotic colon (both 4 days; p = 0.5) and rectal (6 vs 4.5 days; p = 0.2) resections. Median operative times were also similar between the two approaches for colon (150.5 vs 169.5 min, p = 0.2) and rectal (197.0 vs 231.5 min, p = 0.9) resections. There was also no difference in operative time between the two approaches for right (median = 137 vs 130.5 min; p = 0.9) and left (median = 162.0 vs 170.5 min; p = 0.6) colectomies. Robotic surgery results in similar operative times and length of stay as laparoscopic surgery for patients undergoing colon and rectal resections. PMID- 29594756 TI - The Molecular Differentiation of Anatomically Paired Left and Right Mantles of the Pacific Oyster Crassostrea gigas. AB - Left-right (L-R) asymmetry is controlled by gene regulation pathways for the L-R axis, and in vertebrates, the gene Pitx2 in TGF-beta signaling pathway plays important roles in the asymmetrical formation of organs. However, less is known about the asymmetries of anatomically identical paired organs, as well as the transcriptional regulation mechanism of the gene Pitx in invertebrates. Here, we report the molecular biological differences between the left and right mantles of an invertebrate, the Pacific oyster Crassostrea gigas, and propose one possible mechanism underlying those differences. RNA sequencing (RNA-seq) analysis indicated that the paired organs showed different gene expression patterns, suggesting possible functional differences in shell formation, pheromone signaling, nerve conduction, the stress response, and other physiological processes. RNA-seq and real-time qPCR analysis indicated high right-side expression of the Pitx homolog (cgPitx) in oyster mantle, supporting a conserved role for Pitx in controlling asymmetry. Methylation-dependent restriction-site associated DNA sequencing (MethylRAD) identified a methylation site in the promoter region of cgPitx and showed significantly different methylation levels between the left and right mantles. This is the first report, to our knowledge, of such a difference in methylation in spiralians, and it was further confirmed in 18 other individuals by using a pyrosequencing assay. The miRNome analysis and the TGF-beta receptor/Smad inhibition experiment further supported that several genes in TGF-beta signaling pathway may be related with the L/R asymmetry of oyster mantles. These results suggested that the molecular differentiation of the oyster's paired left and right mantles is significant, TGF-beta signaling pathway could be involved in establishing or maintaining the asymmetry, and the cgPitx gene as one of genes in this pathway; the different methylation levels in its promoter regions between L/R mantles was the one of possible mechanisms regulating the left-right functional differentiation. PMID- 29594758 TI - Voltammetric chiral discrimination of tryptophan using a multilayer nanocomposite with implemented amino-modified beta-cyclodextrin as recognition element. AB - An electrochemical chiral multilayer nanocomposite was prepared by modifying a glassy carbon electrode (GCE) via opposite-charge adsorption of amino-modified beta-cyclodextrin (NH2-beta-CD), gold-platinum core-shell microspheres (Au@Pts), polyethyleneimine (PEI), and multi-walled carbon nanotubes (MWCNTs). The modified GCE was applied to the enantioselective voltammetric determination of tryprophan (Trp). The Au@Pts enable an effective immobilization of the chiral selector (NH2 beta-CD) and enhance the electrochemical performance. Scanning electron microscopy, transmission electron microscopy, UV-vis spectroscopy, FTIR and electrochemical methods were used to characterize the nanocomposite. Trp enantiomers were then determined by differential pulse voltammetry (DPV) (with a peak potential of +0.7 V vs. Ag/AgCl). The recognition efficiency was expressed by an increase in peak height by about 32% for DPV determinations of L-Trp compared to D-Trp in case of a 5 mM Trp solution of pH 7.0. Response was linear in the 10 MUM to 5.0 mM concentration range, and the limits of detection were 4.3 MUM and 5.6 MUM with electrochemical sensitivity of 43.5 MUA.MUM-1.cm-2 and 34.6 MUA.MUM-1.cm-2 for L-Trp and D-Trp, respectively (at S/N = 3). Graphical Abstract Schematic of an electrochemical chiral multilayer nanocomposite composed of multi walled carbon nanotubes (MWCNTs), polyethyleneimine (PEI), gold-platinum core shell microspheres (Au@Pt) and amino-modified beta-cyclodextrin (NH2-beta-CD).

PMID- 29594759 TI - MCP-1 is overexpressed in triple-negative breast cancers and drives cancer invasiveness and metastasis. AB - BACKGROUND: Triple-negative breast cancer (TNBC) is the most aggressive type of breast cancer that lacks ER/PR and HER2 receptors. Hence, there is urgency in developing new or novel therapeutic strategies for treatment of TNBC. Our study shows that the Monocyte Chemoattractant Protein-1 (MCP-1) is a marker associated with TNBC and may play a key role in TNBC disease progression. EXPERIMENTAL DESIGN: ELISA method was used to measure secreted MCP-1, and mRNA levels were determined by Real-time PCR in numerous cancer cell lines, representing various breast cancer subtypes. Cellular invasiveness was determined by Boyden chamber assay. RESULTS: Our data show that MCP-1 is upregulated in TNBC cell lines both transcriptionally as well as in secreted protein levels compared to ER-positive luminal cell line, MCF-7. Breast cancer patients, with Basal or Claudin-low subtypes, also showed high expression of MCP-1. MCP-1 treatment induced cell invasion in various breast cancer cell types, without affecting cell proliferation. Small molecule antagonists against Chemokine Receptor 2 (CCR2), cognate receptor for MCP-1 as well as the MAP kinase pathway inhibitor U0126 negatively affected MCP-1 induced MCF-7 cell invasion. This suggests that MCP-1 CCR2 axis may regulate invasiveness via the MAP Kinase pathway. Knocking down MCP 1 decreased cell invasion in TNBC cell line BT-549, along with downregulation of key epithelial to mesenchymal transition markers, N-cadherin and Vimentin. CONCLUSION: Our study suggests that MCP-1 mediated pathways could be potential therapeutic targets for the treatment of TNBC, and could reduce cancer health disparities. PMID- 29594761 TI - Amperometric nonenzymatic sensing of glucose at very low working potential by using a nanoporous PdAuNi ternary alloy. AB - The authors present a nonenzymatic sensor for glucose that has an exceedingly low working potential which makes the sensor highly selective over other electroactive species. The sensor is based on the use of a glassy carbon electrode (GCE) that was modified with a nanoporous PdAuNi alloy (np-PdAuNi). The PdAuNi alloy nanostructure displays enhanced electrocatalytic activity for glucose oxidation (compared to PdNi alloys). The modified GCE enables amperometric sensing of glucose at a typical working electrode potential of 0.0 V vs. SCE in solutions of pH 13 containing 0.1 M NaCl. Response is linear in the 5 to 100 MUM concentration range, with a 1.7 MUM detection limit (at an S/N ratio of 3). For higher concentrations deviations from linearity were found. The method is selective and reproducible. The modified electrode was applied to the determination of glucose in human serum. Graphical Abstract Nanoporous PdAuNi alloy with three-dimensional bicontinuous nanosponge architecture was successfully prepared via chemical dealloying. The electrochemical nonenzymatic glucose sensor shows a low working potential, wide linear range, good sensitivity, low detection limit and excellent selectivity. PMID- 29594760 TI - CMV Infection in Pediatric IBD. AB - PURPOSE OF REVIEW: Patients with inflammatory bowel disease (IBD) are predisposed to infections. Cytomegalovirus (CMV) colitis in adult IBD patients, particularly ulcerative colitis (UC), is related to severe or steroid-refractory disease. The aim of this review is to summarize the data on the prevalence and role of CMV colitis in children with IBD. RECENT FINDINGS: Data on CMV colitis in children continue to be very limited due to its rarity. As in adults, children with coexisting UC and CMV tend to have more severe colitis, are resistant to corticosteroids, and are at high risk for colectomies on short- and long-term follow-up. In children, as in adults, the significance of CMV colitis, in terms of whether CMV is a pathogen that aggravates acute severe colitis or simply reflects disease severity, is still unknown.

PMID- 29594762 TI - Folic acid modified copper nanoclusters for fluorescent imaging of cancer cells with over-expressed folate receptor. AB - Water-soluble and functional copper nanoclusters (CuNCs) were prepared by using folic acid (FA) that serves both as a reducing reagent and a stabilizer. FA also acts as a functional ligand on the surface of the CuNCs, and this can be exploited to target the folate receptor which is over-expressed on the surface of HeLa cells. The FA-modified CuNCs nanoclusters have an average size of ca. 0.9 nm and are stable in aqueous medium for 30 days. Under photoexcitation at lambdaex 270 and 350 nm, the FA-CuNCs display strong blue fluorescence with an emission peak at 440 nm. The FA-CuNCs exhibit low cytotoxicity and favorable biocompatibility as demonstrated by an MTT assay. A cell viability of >80% is found when incubating HeLa cells for 20 h with FA-CuNCs at levels of up to 200 MUg mL-1. The targeting capability of the FA-CuNCs is demonstrated by live cell imaging. It is shown that HeLa cells with over-expressed folate receptor are much brighter than A549 cells where the receptor is not over-expressed. This is further corroborated by the fact that the copper content in HeLa cells (1.5 pg/cell) is 6.5-fold higher than that of A549 cells (0.23 pg/cell), both measured after the same incubation time of 3 h. If free FA is introduced into the cell culture medium, the folate receptors will be preoccupied with FA, and this results in a significant decrease in the cellular uptake of the FA-CuNCs by HeLa cells. Graphical Abstract Biocompatible copper nanoclusters (CuNCs) coated with folic acid (FA) were prepared and are shown to be viable probes for the differentiation between FR-positive HeLa cells and FR-negative A549 cells. PMID- 29594764 TI - Computer-Aided Drug Design: An Overview. AB - The term drug design describes the search of novel compounds with biological activity, on a systematic basis. In its most common form, it involves modification of a known active scaffold or linking known active scaffolds, although de novo drug design (i.e., from scratch) is also possible. Though highly interrelated, identification of active scaffolds should be conceptually separated from drug design. Traditionally, the drug design process has focused on the molecular determinants of the interactions between the drug and its known or intended molecular target. Nevertheless, current drug design also takes into consideration other relevant processes than influence drug efficacy and safety (e.g., bioavailability, metabolic stability, interaction with antitargets).This chapter provides an overview on possible approaches to identify active scaffolds (including in silico approximations to approach that task) and computational methods to guide the subsequent optimization process. It also discusses in which situations each of the overviewed techniques is more appropriate.

AB - Identification of drug targets and drug target interactions are important steps in the drug-discovery pipeline. Successful computational prediction methods can reduce the cost and time demanded by the experimental methods. Knowledge of putative drug targets and their interactions can be very useful for drug repurposing.

Progress in key areas such as molecular and structural biology has contributed to the elucidation of the three-dimensional structure and function of a wide range of biological molecules of therapeutic interest. In this context, the integration of experimental techniques, such as X-ray crystallography, and computational methods, such as molecular docking, has promoted the emergence of several areas in drug discovery, such as structure-based drug design (SBDD). SBDD strategies have been broadly used to identify, predict and optimize the activity of small molecules toward a molecular target and have contributed to major scientific breakthroughs in pharmaceutical R&D. This chapter outlines molecular docking and structure-based virtual screening (SBVS) protocols used to predict the interaction of small molecules with the phosphatidylinositol-bisphosphate-kinase PI3Kdelta, which is a molecular target for hematological diseases. A detailed description of the molecular docking and SBVS procedures and an evaluation of the results are provided. PMID- 29594767 TI - Phylogenetic and Other Conservation-Based Approaches to Predict Protein Functional Sites. AB - Proteins use their functional regions to exploit various activities, including binding to other proteins, nucleic acids, or drugs. Functional sites of the proteins have a tendency to be more conserved than the rest of the protein surface. Therefore, detection of the conserved residues using phylogenetic analysis is a general approach to predict functionally critical residues. In this chapter, we describe some of the available methods to predict functional sites and demonstrate a complete pipeline with tool alternatives at several steps. We explain the standard procedure and all intermediate stages including homology detection with BLAST search, multiple sequence alignment (MSA) and the construction of a phylogenetic tree for a given query sequence. Additionally, we demonstrate the prediction results of these methods on a case study. Finally, we discuss the possible challenges and bottlenecks throughout the pipeline. Our step by-step description about the functional site prediction could be a helpful resource for the researchers interested in finding protein functional sites, to be used in drug discovery research.

PMID- 29594769 TI - Molecular Dynamics Simulation and Prediction of Druggable Binding Sites. AB - Binding site identification and druggability evaluation are two essential steps in structure-based drug design. A druggable binding site tends to have high binding affinity to drug-like molecules. Predicting such sites can have a significant impact on a drug design campaign. This chapter focuses on summarizing the different methods that are used to predict druggable binding sites. The chapter also discusses the importance of including protein flexibility in the search process and the use of molecular dynamics simulations to address this aspect. Case studies from the literature are also summarized and discussed. We hope that this chapter would provide an overview on the different methods employed in binding site identification evaluation. PMID- 29594770 TI - Virtual Ligand Screening Using PL-PatchSurfer2, a Molecular Surface-Based Protein Ligand Docking Method. AB - Virtual screening is a computational technique for predicting a potent binding compound for a receptor protein from a ligand library. It has been a widely used in the drug discovery field to reduce the efforts of medicinal chemists to find hit compounds by experiments.Here, we introduce our novel structure-based virtual screening program, PL-PatchSurfer, which uses molecular surface representation with the three-dimensional Zernike descriptors, which is an effective mathematical representation for identifying physicochemical complementarities between local surfaces of a target protein and a ligand. The advantage of the surface-patch description is its tolerance on a receptor and compound structure variation. PL-PatchSurfer2 achieves higher accuracy on apo form and computationally modeled receptor structures than conventional structure-based virtual screening programs. Thus, PL-PatchSurfer2 opens up an opportunity for targets that do not have their crystal structures. The program is provided as a stand-alone program at http://kiharalab.org/plps2 . We also provide files for two ligand libraries, ChEMBL and ZINC Drug-like. PMID- 29594771 TI - Fragment-Based Ligand Designing. AB - Fragment-based drug design strategies have been used in drug discovery since it was first demonstrated using experimental structural biology techniques such as nuclear magnetic resonance (NMR) and X-ray crystallography. The underlying idea is that existing or new chemical entities with known desirable properties may serve both as tool compounds and as starting points for hit-to-lead expansion. Despite the recent advancements, there remain challenges to overcome, such as assembly of the synthetically feasible structures, development of scoring functions to correlate structure and their activities, and fine tuning of the promising molecules. This chapter first covers the theoretical background needed to understand the concepts and the challenges related to the field of study, followed by the description of important protocols and related software. Case studies are presented to demonstrate practical applications. PMID- 29594772 TI - Molecular Dynamics as a Tool for Virtual Ligand Screening. AB - Rational drug design is essential for new drugs to emerge, especially when the structure of a target protein or catalytic enzyme is known experimentally. To that purpose, high-throughput virtual ligand screening campaigns aim at discovering computationally new binding molecules or fragments to inhibit a particular protein interaction or biological activity. The virtual ligand screening process often relies on docking methods which allow predicting the binding of a molecule into a biological target structure with a correct conformation and the best possible affinity. The docking method itself is not sufficient as it suffers from several and crucial limitations (lack of protein flexibility information, no solvation effects, poor scoring functions, and unreliable molecular affinity estimation).At the interface of computer techniques and drug discovery, molecular dynamics (MD) allows introducing protein flexibility before or after a docking protocol, refining the structure of protein drug complexes in the presence of water, ions and even in membrane-like environments, and ranking complexes with more accurate binding energy calculations. In this chapter we describe the up-to-date MD protocols that are mandatory supporting tools in the virtual ligand screening (VS) process. Using docking in combination with MD is one of the best computer-aided drug design protocols nowadays. It has proved its efficiency through many examples, described below.

AB - Potential drug targets for the disease treatment can be identified from microarray studies on differential gene expression of patients and healthy participants. Here, we describe a method to use the information of differentially expressed (DE) genes obtained from microarray studies to build molecular interaction networks for identification of pivotal molecules as potential drug targets. The quality control and normalization of the microarray data are conducted with R packages simpleaffy and affy, respectively. The DE genes with adjusted P values less than 0.05 and log fold changes larger than 1 or less than 1 are identified by limma package to construct a molecular interaction network with InnateDB. The genes with significant connectivity are identified by the Cytoscape app jActiveModules. The interactions among the genes within a module are tested by psych package to determine their associations. The gene pairs with significant association and known protein structures according to the Protein Data Bank are selected as potential drug targets. As an example for drug target screening, we demonstrate how to identify potential drug targets from a molecular interaction network constructed with the DE genes of significant connectivity, using a microarray dataset of type 2 diabetes mellitus. PMID- 29594774 TI - Absolute Alchemical Free Energy Calculations for Ligand Binding: A Beginner's Guide. AB - Many thermodynamic quantities can be extracted from computer simulations that generate an ensemble of microstates according to the principles of statistical mechanics. Among these quantities is the free energy of binding of a small molecule to a macromolecule, such as a protein. Here, we present an introductory overview of a protocol that allows for the estimation of ligand binding free energies via molecular dynamics simulations. While we focus on the binding of organic molecules to proteins, the approach is in principle transferable to any pair of molecules. PMID- 29594775 TI - Evaluation of Protein-Ligand Docking by Cyscore. AB - Protein-ligand docking is a powerful method in drug discovery. The reliability of docking can be quantified by RMSD between a docking structure and an experimentally determined one. However, most experimentally determined structures are not available in practice. Evaluation by scoring functions is an alternative for assessing protein-ligand docking results. This chapter first provides a brief introduction to scoring methods used in docking. Then details are provided on how to use Cyscore programs. Finally it describes a case study for evaluation of protein-ligand docking. PMID- 29594776 TI - Molecular Dynamics Simulations of Protein-Drug Complexes: A Computational Protocol for Investigating the Interactions of Small-Molecule Therapeutics with Biological Targets and Biosensors. AB - MD simulations provide a powerful tool for the investigation of protein-drug complexes. The following chapter uses the aryl acylamidase-acetaminophen system as an example to describe a general protocol for preparing and running simulations of protein-drug complexes, complete with a step-by-step tutorial. The described approach is broadly applicable toward the study of drug interactions in the context of both biological targets and biosensing enzymes. PMID- 29594777 TI - Prediction and Optimization of Pharmacokinetic and Toxicity Properties of the Ligand. AB - A crucial factor for the approval and success of any drug is how it behaves in the body. Many drugs, however, do not reach the market due to poor efficacy or unacceptable side effects. It is therefore important to take these into consideration early in the drug development process, both in the prioritization of potential hits, and optimization of lead compounds. In silico approaches offer a cost and time-effective approach to rapidly screen and optimize pharmacokinetic and toxicity properties. Here we demonstrate the use of the comprehensive analysis system pkCSM, to allow early identification of potential problems, prioritization of hits, and optimization of leads. PMID- 29594778 TI - Protein-Protein Docking in Drug Design and Discovery. AB - Protein-protein interactions (PPIs) are responsible for a number of key physiological processes in the living cells and underlie the pathomechanism of many diseases. Nowadays, along with the concept of so-called "hot spots" in protein-protein interactions, which are well-defined interface regions responsible for most of the binding energy, these interfaces can be targeted with modulators. In order to apply structure-based design techniques to design PPIs modulators, a three-dimensional structure of protein complex has to be available. In this context in silico approaches, in particular protein-protein docking, are a valuable complement to experimental methods for elucidating 3D structure of protein complexes. Protein-protein docking is easy to use and does not require significant computer resources and time (in contrast to molecular dynamics) and it results in 3D structure of a protein complex (in contrast to sequence-based methods of predicting binding interfaces). However, protein-protein docking cannot address all the aspects of protein dynamics, in particular the global conformational changes during protein complex formation. In spite of this fact, protein-protein docking is widely used to model complexes of water-soluble proteins and less commonly to predict structures of transmembrane protein assemblies, including dimers and oligomers of G protein-coupled receptors (GPCRs). In this chapter we review the principles of protein-protein docking, available algorithms and software and discuss the recent examples, benefits, and drawbacks of protein-protein docking application to water-soluble proteins, membrane anchoring and transmembrane proteins, including GPCRs. PMID- 29594779 TI - Automated Inference of Chemical Discriminants of Biological Activity. AB - Ligand-based virtual screening has become a standard technique for the efficient discovery of bioactive small molecules. Following assays to determine the activity of compounds selected by virtual screening, or other approaches in which dozens to thousands of molecules have been tested, machine learning techniques make it straightforward to discover the patterns of chemical groups that correlate with the desired biological activity. Defining the chemical features that generate activity can be used to guide the selection of molecules for subsequent rounds of screening and assaying, as well as help design new, more active molecules for organic synthesis.The quantitative structure-activity relationship machine learning protocols we describe here, using decision trees, random forests, and sequential feature selection, take as input the chemical structure of a single, known active small molecule (e.g., an inhibitor, agonist, or substrate) for comparison with the structure of each tested molecule. Knowledge of the atomic structure of the protein target and its interactions with the active compound are not required. These protocols can be modified and applied to any data set that consists of a series of measured structural, chemical, or other features for each tested molecule, along with the experimentally measured value of the response variable you would like to predict or optimize for your project, for instance, inhibitory activity in a biological assay or DeltaGbinding. To illustrate the use of different machine learning algorithms, we step through the analysis of a dataset of inhibitor candidates from virtual screening that were tested recently for their ability to inhibit GPCR-mediated signaling in a vertebrate. PMID- 29594780 TI - Computational Exploration of Conformational Transitions in Protein Drug Targets. AB - Protein drug targets vary from highly structured to completely disordered; either way dynamics governs function. Hence, understanding the dynamical aspects of how protein targets function can enable improved interventions with drug molecules. Computational approaches offer highly detailed structural models of protein dynamics which are becoming more predictive as model quality and sampling power improve. However, the most advanced and popular models still have errors owing to imperfect parameter sets and often cannot access longer timescales of many crucial biological processes. Experimental approaches offer more certainty but can struggle to detect and measure lightly populated conformations of target proteins and subtle allostery. An emerging solution is to integrate available experimental data into advanced molecular simulations. In the future, molecular simulation in combination with experimental data may be able to offer detailed models of important drug targets such that improved functional mechanisms or selectivity can be accessed. PMID- 29594781 TI - Applications of the NRGsuite and the Molecular Docking Software FlexAID in Computational Drug Discovery and Design. AB - Docking simulations help us understand molecular interactions. Here we present a hands-on tutorial to utilize FlexAID (Flexible Artificial Intelligence Docking), an open source molecular docking software between ligands such as small molecules or peptides and macromolecules such as proteins and nucleic acids. The tutorial uses the NRGsuite PyMOL plugin graphical user interface to set up and visualize docking simulations in real time as well as detect and refine target cavities. The ease of use of FlexAID and the NRGsuite combined with its superior performance relative to widely used docking software provides nonexperts with an important tool to understand molecular interactions with direct applications in structure-based drug design and virtual high-throughput screening. PMID- 29594782 TI - Calculation of Thermodynamic Properties of Bound Water Molecules. AB - Water molecules in the binding site of a protein significantly influence protein structure and function, for example, by mediating protein-ligand interactions or in form of desolvation as driving force for ligand binding. The knowledge about location and thermodynamic properties of water molecules in the binding site is crucial to the understanding of protein function. This chapter describes the method of calculating the location and thermodynamic properties of bound water molecules from molecular dynamics (MD) simulation trajectories. Thermodynamic profiles of water molecules can be calculated either with or without the presence of a bound ligand based on the scientific problem. The location and thermodynamic profile of hydration sites mediating the protein-ligand interactions is important for understanding protein-ligand binding. The protein desolvation free energy can be estimated for any ligand by summation of the hydration site free energies of the displaced hydration sites. The WATsite program with an easy-to-use graphical user interface (GUI) based on PyMOL was developed for those calculations and is discussed in this chapter. The WATsite program and its PyMOL plugin are available free of charge from http://people.pharmacy.purdue.edu/~mlill/software/watsite/version3.shtml . PMID- 29594783 TI - Enhanced Molecular Dynamics Methods Applied to Drug Design Projects. AB - Nobel Laureate Richard P. Feynman stated: "[...] everything that living things do can be understood in terms of jiggling and wiggling of atoms [...]." The importance of computer simulations of macromolecules, which use classical mechanics principles to describe atom behavior, is widely acknowledged and nowadays, they are applied in many fields such as material sciences and drug discovery. With the increase of computing power, molecular dynamics simulations can be applied to understand biological mechanisms at realistic timescales. In this chapter, we share our computational experience providing a global view of two of the widely used enhanced molecular dynamics methods to study protein structure and dynamics through the description of their characteristics, limits and we provide some examples of their applications in drug design. We also discuss the appropriate choice of software and hardware. In a detailed practical procedure, we describe how to set up, run, and analyze two main molecular dynamics methods, the umbrella sampling (US) and the accelerated molecular dynamics (aMD) methods. PMID- 29594784 TI - AGGRESCAN3D: Toward the Prediction of the Aggregation Propensities of Protein Structures. AB - Protein aggregation is responsible for the onset and spread of many human diseases, ranging from neurodegenerative disorders to cancer and diabetes. Moreover, it is one of the major bottlenecks for the production of protein-based therapeutics such as antibodies or enzymes. AGGRESCAN3D (A3D) is a web server aimed to identify and evaluate structural aggregation prone regions, overcoming the limitations of sequence-based algorithms in the prediction of the aggregation propensity of globular proteins. A3D allows the redesign of protein solubility by predicting in silico the impact of mutations and protein conformational fluctuations on the aggregation of native polypeptides. PMID- 29594785 TI - Computational Analysis of Solvent Inclusion in Docking Studies of Protein Glycosaminoglycan Systems. AB - Glycosaminoglycans (GAGs) are a class of anionic linear periodic polysaccharides, which play a key role in many cell signaling related processes via interactions with their protein targets. In silico analysis and, in particular, application of molecular docking approaches to these systems still experience many challenges including the need of proper treatment of solvent, which is crucial for protein GAG interactions. Here, we describe two methods which we developed, to include solvent in the docking studies of protein-GAG systems: the first one allows to de novo predict favorable positions of water molecules as a part of a rigid receptor to be used for further molecular docking; the second one utilizes targeted molecular dynamics in explicit solvent for molecular docking. PMID- 29594786 TI - Understanding G Protein-Coupled Receptor Allostery via Molecular Dynamics Simulations: Implications for Drug Discovery. AB - Unraveling the mystery of protein allostery has been one of the greatest challenges in both structural and computational biology. However, recent advances in computational methods, particularly molecular dynamics (MD) simulations, have led to its utility as a powerful and popular tool for the study of protein allostery. By capturing the motions of a protein's constituent atoms, simulations can enable the discovery of allosteric hot spots and the determination of the mechanistic basis for allostery. These structural and dynamic studies can provide a foundation for a wide range of applications, including rational drug design and protein engineering. In our laboratory, the use of MD simulations and network analysis assisted in the elucidation of the allosteric hotspots and intracellular signal transduction of G protein-coupled receptors (GPCRs), primarily on one of the adenosine receptor subtypes, A2A adenosine receptor (A2AAR). In this chapter, we describe a method for calculating the map of allosteric signal flow in different GPCR conformational states and illustrate how these concepts have been utilized in understanding the mechanism of GPCR allostery. These structural studies will provide valuable insights into the allosteric and orthosteric modulations that would be of great help to design novel drugs targeting GPCRs in pathological states. PMID- 29594787 TI - Identification of Potential MicroRNA Biomarkers by Meta-analysis. AB - Meta-analysis statistically assesses the results (e.g., effect sizes) across independent studies that are conducted in accordance with similar protocols and objectives. Current genomic meta-analysis studies do not perform extensive re analysis on raw data because full data access would not be commonplace, although the best practice of open research for sharing well-formed data have been actively advocated. This chapter describes a simple and easy-to-follow method for conducting meta-analysis of multiple studies without using raw data. Examples for meta-analysis of microRNAs (miRNAs) are provided to illustrate the method. MiRNAs are potential biomarkers for early diagnosis and epigenetic monitoring of diseases. A number of miRNAs have been identified to be differentially expressed, i.e., overexpressed or underexpressed, under diseased states but only a small fraction would be highly effective biomarkers or therapeutic targets of diseases. The meta-analysis method as described in this chapter aims to identify the miRNAs that are consistently found dysregulated across independent studies as biomarkers. PMID- 29594788 TI - The effects of chalazion surgery on intraocular pressure and corneal topography. AB - PURPOSE: To evaluate the effects of chalazion surgery on intraocular pressure (IOP) and the biomechanical, topographic, and topometric properties of the cornea. METHODS: A total of 29 patients with upper eyelid chalazion were included in this study. All patients underwent preoperative and postoperative detailed ophthalmological examinations including scale of chalazion size; IOP (IOPcc and IOPg), corneal hysteresis, and corneal resistance factor measurements using ocular response analyser (ORA; Reichert Instruments, Depew, NY, USA); topographic and topometric properties of the cornea using Pentacam HR (Oculus GmbH, Wetzlar, HE, Germany). Preoperative and postoperative measurements were compared. RESULTS: The mean age of the patients was 29.07 +/- 13.74 years (18-54 years). The mean IOPcc was 15.82 +/- 4.20 mmHg preoperatively and 14.72 +/- 3.96 mmHg postoperatively, and the mean IOPg was 15.21 +/- 3.91 mmHg preoperatively and 14.21 +/- 4.02 mmHg postoperatively (p = 0.020, p = 0.007, respectively). The mean central keratoconus index (CKI) was 1.006 +/- 0.01 preoperatively and 1.002 +/- 0.01 postoperatively (p = 0.035). Other biomechanical, keratometric, topographic, and topometric parameters were similar before and after the surgery (all p > 0.05). CONCLUSION: To the best of our knowledge, this is the first report to suggest that IOP and CKI are decreased after the removal of upper eyelid chalazion. PMID- 29594789 TI - Outcomes of presbyopia-correcting intraocular lenses after laser in situ keratomileusis. AB - BACKGROUND: Laser in situ keratomileusis (LASIK) is the most common refractive surgery in young patients, which aims at providing a clear distance vision without the use of spectacles. With time, these patients develop symptomatic cataract, which affects activities of daily living, and to improve visual acuity, intraocular lens (IOL) implantation can be considered. In post-myopic LASIK patients, to allow continuation of spectacle independence, the implantation of presbyopia-correcting IOLs is a suitable option. The purpose of this retrospective case series is to report the visual outcome and quality in post myopic LASIK eyes after the implantation of AT LISA tri839MP IOL. METHOD: Twenty eyes of 13 patients with history of myopic LASIK within 20 years underwent phacoemulsification by one single surgeon. All eyes were implanted with AT LISA tri839PMP IOL, and their outcomes were evaluated at 6 months postoperation. RESULTS: The mean postoperative uncorrected distance visual acuity (VA) is 0.28 +/- 0.29, while the corrected distance VA is 0.06 +/- 0.14. The mean postoperative uncorrected near VA is 0.02 +/- 0.05, while the corrected near VA is 0.01 +/- 0.02. The mean postoperative manifest refraction spherical equivalent (SE) is - 0.92 +/- 0.76D. There is a statistically significant difference between the preoperative and postoperative refraction (p = 0.02), which shows a postoperative myopic shift. There is also a statistically significant difference between the mean targeted SE and postoperative manifest refraction SE (p = 0.00). Only one out of 20 eyes (5%) reported halo and glare symptoms. Ten out of 20 eyes (50%) are able to achieve spectacles independence. CONCLUSION: In conclusion, in post-myopic LASIK eyes, AT LISA tri839MP provides a good visual outcome at both near and distance, but is more predictable at near than at distance. There is a myopic shift in the postoperative SE. Visual quality is satisfactory and has not been exacerbated. Most patients can remain to be spectacles free at all distances. PMID- 29594790 TI - Resolution of arterial aneurysms in idiopathic retinal vasculitis, aneurysms and neuroretinitis: a case report and review of literature. AB - PURPOSE: To report a case of resolution of retinal arterial aneurysms in a patient of idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) treated with oral steroids. METHODS: This study contains case report and review of literature. RESULTS: A 16-year-old girl with stage 2 IRVAN was treated with oral steroids alone. Fluorescein angiography confirmed the presence of aneurysms and absence of neovascularization in both eyes. The aneurysms resolved gradually over 4-month follow-up. CONCLUSIONS: This case demonstrates previously unreported reversibility of arterial aneurysms with steroid therapy alone in early stages of IRVAN. PMID- 29594791 TI - Repair of angle recession prevents pupillary capture of intrasclerally fixed intraocular lenses. AB - PURPOSE: We evaluated a new concept for treating pupillary capture of the intraocular lens (IOL) following intrascleral fixation of the IOL. Pupillary capture of the IOL is a common postoperative complication that occurs after suturing and intrascleral fixation of the IOL. In such cases, blunt trauma is often related to zonular dialysis, iris retraction, iridodonesis, and angle recession. Several methods such as barricading by suturing, pupilloplasty, and pars plana fixation are reported to prevent pupillary capture. Although effective, none of these techniques fix iris-malposition and angle recession. We considered that repairing angle recession could correct the iris position and prevent pupillary capture recurrence. METHODS: We repaired angle recession in four cases and have followed up. RESULTS: Pupillary capture was not observed in all three cases of larger IOLs for more than 9 months, but observed after 1 month in an IOL with normal 6 mm diameter, in which the angle was not properly lifted. CONCLUSION: In select cases, repairing angle recession may be useful for preventing pupillary capture after IOL suturing and intrascleral fixation. PMID- 29594792 TI - Ocular surface and respiratory tract damages from occupational, sub-chronic exposure to fluorspar: case report and other considerations. AB - OBJECTIVES: To report the ocular surface and respiratory tract damages due to a sub-chronic (3 months), occupational exposure to fluorspar dust in case of inconsistent use of personal protective equipment. METHODS: A 50-year-old man was referred to our clinic with bilateral conjunctival injection, ocular foreign body sensation and symptoms of ocular discomfort. He reported having 3 days before an urgent hospital admission for dyspnoea with odynophagia, hyposmia, nausea, vomiting, headache and asthenia. Otorhinolaryngological examination revealed a severe hypertrophic rhinopharyngitis and a significant decrease in overall sensitivity to olfactory stimuli. General anamnesis was negative for previous diseases or medication use. RESULTS: Ocular examination revealed a diffuse injection of the ocular surface with some areas of conjunctival and limbal ischaemia, a best-corrected visual acuity of 20/25 in both eyes, an intraocular pressure of 23 and 21 mmHg, respectively, in the right and in the left eyes, and a normal fundus oculi. Assessment of the tear film and ocular surface showed the presence of dry eye disease. Based on medical history and clinical tests, initial diagnostic hypothesis was ocular surface burn due to chemical exposure, i.e. to fluorspar. Therefore, anterior segment fluorescein angiography was performed to confirm the extension of conjunctival and limbal ischaemia. Thus, ocular ischaemia was detected in approximately 10 clock hours of limbus and in 50% of conjunctiva. CONCLUSIONS: The present work remarks the importance of using protective equipment for preventing ocular and respiratory tract damages in workers occupationally exposed to the 'acid-grade fluorite'. PMID- 29594793 TI - Sterile keratitis after uneventful corneal collagen cross-linking in a patient with Axenfeld-Rieger syndrome. AB - PURPOSE: To report on a keratoconus (KC) patient with Axenfeld-Rieger syndrome (ARS) who developed sterile keratitis after accelerated corneal collagen cross linking (CXL). METHODS: An 18-year-old patient with ARS and KC who had previously undergone intrastromal ring segment implantation underwent accelerated CXL (9 mW/cm2 UVA intensity for 10 min). RESULTS: After uneventful surgery, the patient presented with severe photophobia, redness of the eye, and decreased vision 72 h following the procedure. Slit-lamp examination showed anterior multiple superficial stromal infiltrates in the central cornea with an overlying epithelium defect. Due to the lack of pain and absence of any pathogen from corneal samples, a diagnosis of sterile keratitis was considered. A combination of topical antibiotic and corticosteroid regimen was administered. Three months after CXL slit-lamp examination showed a mild stromal scar overlying the central cornea, which did not decrease visual acuity. CONCLUSIONS: The mechanism by which the sterile keratitis occurs following CXL remains unclear. For our case, the reason of post-CXL sterile keratitis could be considered as an immune response due to the staphylococcal antigens. Furthermore, the possible developmental disturbance of corneal stroma in ARS might have contributed to the development of post-CXL sterile keratitis. PMID- 29594794 TI - Case series of coexistence of polypoidal choroidal vasculopathy with other rare fundus diseases. AB - PURPOSE: To record the coexistence of polypoidal choroidal vasculopathy (PCV) with other rare fundus diseases in a Chinese population. METHOD: In this retrospective hospital-based study, a chart review of 861 patients with newly diagnosed PCV was performed. The clinical features of rare fundus comorbidities of PCV were recorded. RESULTS: Five eyes of 5 patients aged 63.4 +/- 11.22 years (0.58%) had PCV coexisting with other fundus diseases in the same eye. Of the 5 PCV patients, 2 (0.23%) had myelinated nerve fiber, 2 (0.23%) had branch retinal vein occlusion, and 1 (0.12%) had retinal angiomatous proliferation. CONCLUSION: We reported rare fundus comorbidities of PCV in a large Chinese cohort. These comorbidities included myelinated nerve fiber, branch retinal vein occlusion and retinal angiomatous proliferation. The combination might constitute an accidental occurrence. PMID- 29594795 TI - Aptamer based fluorometric sulfamethazine assay based on the use of graphene oxide quantum dots. AB - The authors have developed a homogeneous "off-on" fluorometric method for the determination of the antibiotic sulfamethazine (SMZ). Aptamer against SMZ was labeled with graphene oxide quantum dots upon which the Graphene oxide quenched the blue fluorescence of the GOQDs. On addition of SMZ, the aptamers will bind SMZ and this will cause the release of GOQDs. As a result, fluorescence will be regenerated. Fluorescence, best measured at excitation/emission wavelengths of 365/455 nm, increases linearly in the 8 pg.mL-1 to 60 ng.mL-1 SMZ concentration range, with a 5 pg.mL-1 detection limit. The method is reliable and was successfully applied to the determination of SMZ in spiked milk samples, with recoveries ranging from 89 to 96% depending on analyte concentration. Graphical abstract Graphene oxide quantum dots (GOQDs) were covalently bound to the aptamer (apt) against sulfamethazine (SMZ) and adsorbed on the surface of graphene oxide (GO). This results in quenching of the fluorescence of GOQDs. On addition of SMZ, fluorescence is restored due to the release of GOQD@apt from GO. PMID- 29594796 TI - Alternative mitochondrial respiratory chains from two crustaceans: Artemia franciscana nauplii and the white shrimp, Litopenaeus vannamei. AB - Mitochondrial ATP is synthesized by coupling between the electron transport chain and complex V. In contrast, physiological uncoupling of these processes allows mitochondria to consume oxygen at high rates without ATP synthesis. Such uncoupling mechanisms prevent reactive oxygen species overproduction. One of these mechanisms are the alternative redox enzymes from the mitochondrial respiratory chain, which may help cells to maintain homeostasis under stress independently of ATP synthesis. To date, no reports have been published on alternative redox enzymes in crustaceans mitochondria. Specific inhibitors were used to identify alternative redox enzymes in mitochondria isolated from Artemia franciscana nauplii, and the white shrimp, Litopenaeus vannamei. We report the presence of two alternative redox enzymes in the respiratory chain of A. franciscana nauplii, whose isolated mitochondria used glycerol-3-phosphate as a substrate, suggesting the existence of a glycerol-3-phosphate dehydrogenase. In addition, cyanide and octyl-gallate were necessary to fully inhibit this species' mitochondrial oxygen consumption, suggesting an alternative oxidase is present. The in-gel activity analysis confirmed that additional mitochondrial redox proteins exist in A. franciscana. A mitochondrial glycerol-3-phosphate dehydrogenase oxidase was identified by protein sequencing as part of a branched respiratory chain, and an alternative oxidase was also identified in this species by western blot. These results indicate different adaptive mechanisms from artemia to face environmental challenges related to the changing levels of oxygen concentration in seawater through their life cycles. No alternative redox enzymes were found in shrimp mitochondria, further efforts will determine the existence of an uncoupling mechanism such as uncoupling proteins. PMID- 29594797 TI - Preparation of a boronate affinity material with ultrahigh binding capacity for cis-diols by grafting polymer brush from polydopamine-coated magnetized graphene oxide. AB - Poly(3-acrylamidophenylboronic acid) (PAAPBA) was grafted onto polydopamine coated magnetic graphene oxide via surface-initiated atom transfer radical polymerization to obtain a new kind of boronate affinity material (BAM). The BAM possesses good water dispersity and adsorption capacities as high as 154, 357, 588 and 1111 MUmol.g-1 for adenosine, salbutamol, dopamine and catechol, respectively. For the molecules without nitrogen atoms, the BAM can selectively capture the cis-diols under the interference of non-cis-diols. For molecules containing nitrogen, the non-cis-diols are also retained, but much less than the cis-diols. The selectivity can be improved by adding salts to facilitate complexation and to suppress the electrostatic interaction between cis-diols and the boronic acid ligand. The BAM was successfully employed to the enrichment of catecholamines from real urine samples. Results indicate that it is a promising material for the pretreatment of real samples. Graphical abstract Schematic of the preparation of an ultrahigh capacity boronate affinity material by grafting polymer brush from polydopamine coated magnetic graphene oxide. The material has good selectivity to cis-diol-containing molecules and can be applied to enrich catecholamines in urine samples. PMID- 29594798 TI - Improved quality of care for patients infected or colonised with ESBL-producing Enterobacteriaceae in a French teaching hospital: impact of an interventional prospective study and development of specific tools. AB - The increasing incidence of ESBL-producing Enterobacteriaceae (ESBL-E) in France prompted the publication of national recommendations in 2010. Based on these, we developed a toolkit and a warning system to optimise management of ESBL-E infected or colonised patients in both community and hospital settings. The impact of this initiative on quality of care was assessed in a teaching hospital. The ESBL toolkit was developed in 2011 during multidisciplinary meetings involving a regional network of hospital, private clinic and laboratory staff in Southeastern France. It includes antibiotic treatment protocols, a check list, mail templates and a patient information sheet focusing on infection control. Upon identification of ESBL-E, the warning system involves alerting the attending physician and the infectious disease (ID) advisor, with immediate, advice-based implementation of the toolkit. The procedure and toolkit were tested in our teaching hospital. Patient management was compared before and after implementation of the toolkit over two 3-month periods (July-October 2010 and 2012). Implementation of the ESBL-E warning system and ESBL-E toolkit was tested for 87 patients in 2010 and 92 patients in 2012, resulting in improved patient management: expert advice sought and followed (16 vs 97%), information provided to the patient's general practitioner (18 vs 63%) and coding of the condition in the patient's medical file (17 vs 59%), respectively. Our multidisciplinary strategy improved quality of care for in-patients infected or colonised with ESBL E, increasing compliance with national recommendations. PMID- 29594799 TI - Managing ESBL-producing Enterobacteriaceae-related urinary tract infection in primary care: a tool kit for general practitioners. AB - In Southern France, approximately 4% of E. coli isolates from community-acquired urinary tract infections are extended spectrum beta-lactamase producers, while carriage rates for enterobacteriaceae (ESBL-E) range from 3 to 6%. General practitioners (GP) are unfamiliar with the management of patients harboring ESBL E. Providing them with a specific tool kit should assist in their therapeutic approach and optimize antimicrobial prescription an ESBL-E tool kit was developed by a multidisciplinary team: infectious diseases (ID) specialists, microbiologists, pharmacologists, and nursing home staff. This tool kit includes treatment protocols, GP and patient information leaflets, a list of infection control measures, and contact details of ID physicians for specialized advice. A community-based (including nursing homes) prospective study was conducted in 2012 in Southeastern France to test the tool kit in the context of ESBL-E-related urinary tract infections (UTI). ESBL-E-related UTI were identified in 88 patients, 66 GPs were contacted by the microbiology laboratory, 56 stated they were offered the tool kit, 48 said they had received it, and 41 stated they had read its contents. Use of the tool kit was significantly correlated with appropriate antibiotic prescription, which concerned 36/39 tool kit users versus 13/20 non-users (p = 0.0125) and 40 GPs expressed an average satisfaction rate of 4.2 on a scale of 0 to 5. Availability of a specific tool for managing patients harboring ESBL-E, now completed with a website, can assist community-based GPs and improve antimicrobial prescription.

AB - To assess the diagnostic and operational performance of the InBiOS AMD rapid diagnostic test (RDT) (Seattle, USA) for the detection of B. pseudomallei in grown blood culture broth. The InBiOS RDT is a lateral flow immunoassay in a strip format detecting B. pseudomallei capsular polysaccharide in culture fluids, marketed for research only. Broth of blood culture bottles (BacT/Alert, bioMerieux, Marcy L'Etoile, France) sampled in adult patients at the Sihanouk Hospital Center of HOPE, Phnom Penh, Cambodia, during 2010-2017 and stored at - 80 degrees C was tested. They included samples grown with B. pseudomallei (n = 114), samples with no growth (n = 12), and samples with growth of other pathogens (n = 139, among which Burkholderia cepacia (n = 5)). Diagnostic sensitivity and specificity were 96.5% [95% confidence interval (CI): 91.3-98.6%] and 100% [CI: 97.5-100%] respectively. Background clearance and line intensities were good and very good. The RDT's test strip, not housed in a cassette, caused difficulties in manipulation and biosafety. The centrifugation step prescribed by the procedure challenged biosafety, but processing of 19 B. pseudomallei samples without centrifugation showed similar results for line intensity and background clearance, compared to centrifugation. The InBiOS RDT showed excellent accuracy for detection of B. pseudomallei in grown blood culture broth. Provided operational adaptations such as cassette housing, it has the potential to reduce time to diagnosis of melioidosis.

AB - The suitability of the model for end-stage liver disease excluding international normalized ratio (MELD-XI) score to predict adverse outcomes in infective endocarditis (IE) patients remains uncertain. This study was performed to explore the prognostic value of the MELD-XI score and modified MELD-XI score for patients with IE. A total of 858 patients with IE were consecutively enrolled and classified into two groups: MELD-XI <= 10 (n = 588) and MELD-XI > 10 (n = 270). Multivariate analysis was performed to determine risk factors independent of MELD XI score. Higher MELD-XI score was associated with higher in-hospital mortality (15.6 vs. 4.8%, p < 0.001) and major adverse clinical events (33.3 vs. 18.4%, p < 0.001). MELD-XI score was an independent predictor of in-hospital death (odds ratio [OR] = 1.06, 95% CI, 1.02-1.10, p = 0.005). Based on a multivariate analysis, NYHA class III or IV (3 points), C-reactive protein > 9.5 mg/L (4 points), and non-surgical treatment (6 points) were added to MELD-XI score. Modified MELD-XI score produced higher predictive power than previous (AUC 0.823 vs. 0.701, p < 0.001). The cumulative incidence of long-term mortality (median 29 months) was significantly higher in patients with modified MELD-XI score > 13 than those without (log-rank = 25.30, p < 0.001). Modified MELD-XI score was independently associated with long-term mortality (hazard ratio = 1.08, 95% CI, 1.04-1.12, p < 0.001). MELD-XI score could be used as a risk assessment tool in IE. Furthermore, modified MELD-XI score remained simple and more effective in predicting poor prognosis.

It is making use of molybdenum disulfide quantum dots (MoS2 QDs) as a fluorescent probe. The QDs are prepared by hydrothermal reaction of sodium molybdate with glutathione. They possess diameters typically ranging from 1.4 to 3.8 nm, excellent stability in water, and blue photoluminescence (with excitation/emission peaks located at 315/412 nm and a quantum yield of 3.7%). The fluorescence of the QDs is statically quenched by hypochlorite, and the Stern Volmer plot is linear. Hypochlorite can be detected in the 5-500 MUM concentration range with a 0.5 MUM detection limit. The method has been successfully applied to the determination of hypochlorite in spiked samples of tap water, lake water, and commercial disinfectants. Graphical abstract Schematic of a method for the fluorometric determination of hypochlorite using MoS2 quantum dots as a fluorescent probe. It has been applied to hypochlorite assay in spiked samples of tap water, lake water, and commercial disinfectants. PMID- 29594802 TI - Molecular strategy for the diagnosis of infectious lymphadenitis. AB - Molecular methods have been considered to be the gold standard for the diagnosis of infectious lymphadenitis. However, culture remains critical in the case of low bacterial concentrations. We used molecular assays and culture to examine fresh lymph node biopsies from patients with suspected infectious lymphadenopathy. We analyzed 1762 lymph node biopsies of which 522 (30%) samples were found positive by real-time PCR; the most commonly amplified bacteria were Bartonella henselae (n = 438, 84%), Francisella tularensis (n = 46, 9%), and Mycobacterium spp. (n = 29, 6%). PCR amplification and sequencing of the 16S rDNA were positive for 359 (20%) lymph node specimens including mainly B. henselae (n = 167, 47%), Staphylococcus spp. (n = 77, 21%), and Streptococcus spp. (n = 41, 11%). In total, 351 lymph nodes were cultured on agar plates and 77 (22%) were positive. Significantly more lymph nodes infected by Gram-positive easy-growing agents were diagnosed by culture (n = 45) than by 16S rDNA PCR (p = 0.02). Culture remains critical for the diagnosis of easy-growing bacteria and mycobacteria; clinicians should be aware that a negative molecular result does not imply absence of infection. PMID- 29594804 TI - A rapid colorimetric immunoassay for the detection of pathogenic bacteria on poultry processing plants using cotton swabs and nanobeads. AB - The work describes a simple cotton swab-based colorimetric immunoassay as a rapid screening tool for pathogenic bacteria on poultry processing plants. This immunosensing platform can be used for the detection of pathogens present on surfaces such as glass, stainless steel and chicken meat. Unlike the reported assays, here, cotton swab plays dual function: as a sample collector from the solid surfaces and as detection platform. The immunoassay was tested for the detection of 4 different bacteria; Salmonella typhimurium, Salmonella enteritidis, Staphylococcus aureus and Campylobacter jejuni. The immunoassays were fabricated by immobilizing specific antibody for each bacterium on a cotton swab that is used to recover the cells from contaminated surfaces. Then, a sandwich immunoassay was developed by immersing the cotton swab in different colored nanobead-conjugated antibody solutions which corresponds to different bacteria. The immunoassays response was detected colorimetrically by following the change in the color intensity produced by the nanobeads due to the specific binding on the cotton swab. This simple colorimetric assay is very sensitive with a detection limit of 10 cfu.mL-1. Furthermore, no significant cross reactivity of the immunoassays with non specific bacteria was observed indicating good selectivity of the immunoassays. This simple, disposable and easy-to- use colorimetric platform shows great promise as rapid qualitative and semi quantitative detection tool for microorganisms on food processing plants and other surfaces.

AB - A glassy carbon electrode was modified with an array of porous Ni3N nanosheets (Ni3N NA) and studied for its use in non-enzymatic electrochemical detection of glucose. The morphology and structure of the Ni3N NA were characterized by scanning electron microscopy and X-ray diffraction. Electrochemical studies demonstrated that the Ni3N NA acts as an efficient catalyst for the electro oxidation of glucose at pH 13, best at a working voltage of 0.55 V (vs. Ag/AgCl). Figures of merit include (a) high sensitivity (39 MUA.mM-1.cm-2), (b) a low limit of detection (0.48 MUM), and (c) a linear range that extends from 2 MUM to 7.5 mM. The sensor was applied to the determination of glucose levels in human serum, and satisfactory results were obtained.

PMID- 29594806 TI - On the calculation of the potential of mean force between atomistic nanoparticles. AB - We study the potential of mean force (PMF) between atomistic silica and gold nanoparticles in the vacuum by using molecular dynamics simulations. Such an investigation is devised in order to fully characterize the effective interactions between atomistic nanoparticles, a crucial step to describe the PMF in high-density coarse-grained polymer nanocomposites. In our study, we first investigate the behavior of silica nanoparticles, considering cases corresponding to different particle sizes and assessing results against an analytic theory developed by Hamaker for a system of Lennard-Jones interacting particles (H.C. Hamaker, Physica A 4, 1058 (1937)). Once validated the procedure, we calculate effective interactions between gold nanoparticles, which are considered both bare and coated with polyethylene chains, in order to investigate the effects of the grafting density [Formula: see text] on the PMF. Upon performing atomistic molecular dynamics simulations, it turns out that silica nanoparticles experience similar interactions regardless of the particle size, the most remarkable difference being a peak in the PMF due to surface interactions, clearly apparent for the larger size. As for bare gold nanoparticles, they are slightly interacting, the strength of the effective force increasing for the coated cases. The profile of the resulting PMF resembles a Lennard-Jones potential for intermediate [Formula: see text], becoming progressively more repulsive for high [Formula: see text] and low interparticle separations. PMID- 29594807 TI - Genetic Polymorphisms in miR-146a, miR-196a2 and miR-125a Genes and its Association in Prostate Cancer. AB - The increase in incidence of prostate cancer in the Indian Population stresses the need to identify genetic markers for susceptibility and prognosis. Recent studies show that microRNAs play an important role in tumorigenesis by altering proliferation, differentiation and cell death. Gene polymorphisms not only in promoter region but also within miRNA gene have been shown to affect expression. The present study was aimed to analyze the role of miR-146a, miR-196a2 and miR 125a gene polymorphisms in prostate cancer. Genotyping of three SNPs rs73318382, rs57095329, rs2910164 in miRNA146a, rs11614913 in miR-196a2 and rs41275794, rs12976445, rs10404453 and rs1297533 in miR-125a was performed in 100 cases and 100 controls. Statistical analysis revealed the heterozygous AG genotype of the rs57095329 was significantly decreased in the cases when compared to the controls (OR-0.45, CI -0.24 to 0.85, p value-0.02) indicating an inverse association of this genotype with prostate cancer. Further the heterozygous CT of miR-196a2 (rs11614913) (OR-1.88, CI-1.06 to 3.35, p-0.02) and homozygous CC of miR-125a (rs12976445) (OR-2.55, CI -1.15 to 4.65, p-0.03) showed increased risk for prostate cancer. Combined analysis of all the genotypes revealed that the haplotype combination AGGCGTGG (OR = 0.09 at CI 95% (0.01-0.65) showed an inverse association with prostate cancer. Stratified analysis based on the age and tumor grade revealed no significant association. PMID- 29594809 TI - Presence of the posterior pituitary bright spot sign on MRI in the general population: a comparison between 1.5 and 3T MRI and between 2D-T1 spin-echo- and 3D-T1 gradient-echo sequences. AB - PURPOSE: To describe the prevalence of the posterior pituitary bright spot (PPBS) in the general population on 1.5 and 3T MRI examinations and on 2D-T1 spin-echo (SE) and 3D-T1 gradient-echo (GE) sequences. MATERIALS AND METHODS: 1017 subjects who received an MRI of the brain for aspecific neurological complaints were included. MRI was performed on 1.5T in 64.5% and on 3T in 35.5% of subjects. Presence of the PPBS was evaluated on sagittal 2D T1-SE echo images with slice thickness 3 mm in 67.5% and on sagittal 3D T1-GE with slice thickness 0.9 mm in 32.5% of subjects. RESULTS: The PPBS was detectable in 95.9% of subjects. After correction for sex and age, no statistically significant difference could be seen concerning PPBS detection between 1.5 and 3T MRI examinations (p = 0.533), nor between 2D T1-SE and 3D T1-GE sequences (p = 0.217). There was a statistically significant association between increasing age and the absence of the PPBS (p < 0.001). The PPBS could not be identified in 6.2% of male subjects, compared to 2.2% of female subjects (p = 0.01). DISCUSSION: Absence of the PPBS can be seen in 4.1% of patients undergoing MRI of the brain for non-endocrinological reasons. Neither field-strength nor the use of a thick-sliced 2D T1-SE versus a thin sliced 3D T1-GE sequence influenced the detectability of the PPBS. There is a statistically significant association between increasing age and male sex and the absence of the PPBS. PMID- 29594810 TI - A sample-to-answer droplet magnetofluidic assay platform for quantitative methylation-specific PCR. AB - Dysregulation of DNA methylation has been identified as an epigenetic biomarker for numerous cancer types. Gene-specific identification techniques relying on methylation-specific PCR (MSP) require a lengthy manual benchtop process that is susceptible to human-error and contamination. This MSP assay requires a series of discrete sample processing steps including genomic DNA extraction, bisulfite conversion and readout via PCR. In this work, we present a streamlined assay platform utilizing droplet magnetofluidic principles for integration of all sample processing steps required to obtain quantitative MSP signal from raw biological samples. We present a streamlined protocol for solid-phase extraction and bisulfite conversion of genomic DNA, which minimizes reagent use and simplifies the sample preparation protocol for implementation on a compact assay platform. Furthermore, we present a thermally robust assay chip that enables DNA extraction, bisulfite conversion and quantitative PCR from biological samples on a single device. Technical improvements to facilitate DNA extraction and PCR on a single chip in addition to chip performance characterization data are presented. PMID- 29594808 TI - Stress Response Modulation Underlying the Psychobiology of Resilience. AB - PURPOSE OF REVIEW: This review focuses on the relationship between resilience and the ability to effectively modulate the stress response. Neurobiological and behavioral responses to stress are highly variable. Exposure to a similar stressor can lead to heterogeneous outcomes-manifesting psychopathology in one individual, but having minimal effect, or even enhancing resilience, in another. We highlight aspects of stress response modulation related to early life development and epigenetics, selected neurobiological and neurochemical systems, and a number of emotional, cognitive, psychosocial, and behavioral factors important in resilience. We also briefly discuss interventions with potential to build and promote resilience. RECENT FINDINGS: Throughout this review, we include evidence from recent preclinical and clinical studies relevant to the psychobiology of resilient stress response modulation. Effective modulation of the stress response is an essential component of resilience and is dependent on a complex interplay of neurobiological and behavioral factors.

AB - Graphene oxide (GO), nanosized Fe3O4 and zeolite imidazolate framework-8 (ZIF-8) were hybridized as a multifunctional sorbent for use in microextraction. The sorbent was characterized by SEM, TEM, XRD and FTIR. The composite is porous, has a high specific surface (> 600 m2.g-1) and is paramagnetic. The GO sheets are shown to act as carriers for the Fe3O4 nanoparticles and ZIF-8. The composite is a viable material for the preconcentration of atorvastatin and simvastatin from urine prior to their determination by HPLC with PDA detection. The limits of detection are 116 and 387 pg.mL-1, respectively. Recoveries from spiked urine samples range between 84.7 and 95.7%, with relative standard deviation of <=4.5%. Enrichment factors range from 169 to 191. The method was successfully applied to the determination of atorvastatin in urine. Moreover, this sorbent is regenerable and recyclable for at least seven times without obvious decrease in performance. Graphical abstract A composite sorbent composed of a zeolite imidazolate framework, Fe3O4 and graphene oxide was applied to the extraction of statins in urine prior their determination by HPLC. PMID- 29594812 TI - Neutrophil-to-Lymphocyte Ratio Is an Independent Predictor of 30-Day Mortality of Intracerebral Hemorrhage Patients: a Validation Cohort Study. AB - In a previous study in patients with intracranial hemorrhage (ICH), we found an association between high neutrophil-to-lymphocyte ratio (NLR) with poor short term mortality. In the current study, this preliminary finding was validated using an independent patient cohort. A total of 181 ICH patients (from January 2016 to December 2017) were included. Diagnosis was confirmed using computed tomography (CT) in all cases. Patient survival (up to 30 days) was compared between subjects with high NLR (above the 7.35 cutoff; n = 74) versus low NLR (<= 7.35; n = 107) using Kaplan-Meier analysis. A multivariate logistic regression was performed to identify factors that influenced the 30-day mortality. Correlation between NLR with other relevant factors (e.g., C-reactive protein (CRP) and fibrinogen) was examined using Spearman correlation analysis. The 30 day mortality was 19.3% (35/181) in the entire sample, 37.8% (28/74) in the high NLR group, and 6.5% (7/107) in the low-NLR group (P < 0.001). In comparison to the low-NLR group, the high-NLR group had higher rate of intraventricular hemorrhage (29.7 vs. 16.8%), ICH volume (median 23.9 vs. 6.0 cm3) and ICH score (median 1.5 vs. 0), and lower GCS score (9.4 +/- 4.5 vs. 12.9 +/- 3.2). An analysis that divided the samples into three equal parts based on NLR also showed increasing 30-day mortality with incremental NLR (1.6, 15.0, and 41.7% from lowest to highest NLR tertile, P for trend < 0.001). Kaplan-Meier curve showed higher 30-day mortality in subjects with high NLR than those with low NLR (P < 0.001 vs. low-NLR group, log-rank test). High NLR (> 7.35) is associated with poor short-term survival in acute ICH patients. PMID- 29594813 TI - A hollow porous molecularly imprinted polymer as a sorbent for the extraction of 7 macrolide antibiotics prior to their determination by HPLC-MS/MS. AB - A hollow porous molecularly imprinted polymer (HPMIP) is described for use in dispersive solid phase extraction of macrolide antibiotics (MACs). The HPMIP was prepared by using spiramycin as the template, methacrylic acid as the functional monomer, and mesoporous MCM-41 (Mobile Composition of Matter No. 41; with a size of about 100 nm) as a sacrificial support. The sorbent was characterized by Fourier transform infrared spectrometry, transmission electron microscopy, nitrogen adsorption and thermo-gravimetric analysis. Several parameters affecting the extraction efficiency were optimized. The material has a large surface area (359 m2.g-1), and most recognition sites are located on the surface of the HPMIPs. This results in high binding capacity (120 MUmol.g-1) and fast binding (20 min) in comparison to either MCM-41-core surface MIPs or solid MIPs. The method was applied to the extraction of the MACs azithromycin, spiramycin, tilmicosin, tylosin, clarithromycin, roxithromycin and josamycin from spiked honey. The recoveries, determined by HPLC-MS/MS, ranged from 88.0% to 117% at the three spiking levels tested (1, 5 and 20 MUg.kg-1). Intra-day and inter-day assay precision at three spiking levels are <10.7% (for n = 6) and 12.6% (n = 3), respectively. The limits of detection are between 3 and 17 ng.kg-1. This indicates the superiority of the method in selective extraction of macrolides even from complex matrices. Graphical abstract Hollow porous molecularly imprinted polymers using spiramycin as the template are shown to be viable dispersive solid phase extraction adsorbents for selective enrichment of macrolide antibiotics in honey products prior to their quantitation by HPLC MS/MS. PMID- 29594814 TI - Novel drugs for heart rate control in heart failure. AB - In patients with heart failure, increased sympathetic activity is associated with a positive chronotropic stimulation leading to accelerated resting heart rate. Elevated heart rate (HR) is a risk factor for cardiovascular events, both in the general population and in patients with heart failure. Ivabradine is a pure HR lowering agent, and it does not affect myocardial contractility, blood pressure, intracardiac conduction, or ventricular repolarization. In clinical trials such as BEAUTIFUL, CARVIVA HF, SHIFT, and INTENSIFY in patients with systolic left ventricular dysfunction, heart rate reduction with ivabradine brought positive outcomes. However, the results of the recent meta-analysis are rather neutral. In a diabetes mouse model of heart failure with preserved ejection fraction (HFpEF), selective heart rate reduction by If inhibition improved vascular stiffness, left ventricular (LV) contractility, and diastolic function. However, EDIFY (Effect of ivabradine in patients with heart rate with preserved ejection fraction) trial show that the use of ivabradine in patients with HFpEF is not supported. The further clinical trials investigating the use of ivabradine in heart failure should be carried out. PMID- 29594815 TI - Has time come for the use of direct oral anticoagulants in the extended prophylaxis of venous thromboembolism in acutely ill medical patients? No. AB - Acutely ill hospitalized medical patients are at high risk of venous thromboembolism (VTE). Although thromboprophylaxis in these patients is recommended since 2004 by the American College of Chest Physicians, it is widely underused. The doubt as to whether or not to treat patients at high VTE risk after hospital discharge came from the knowledge that this risk may persist after the hospital admission period. Two meta-analyses comparing extended- versus short duration prophylaxis are published. The results demonstrate an unfavorable balance between VTE prevention and incidence of major bleeding in patients assigned to extended-duration thromboprophylaxis. Only in the APEX study, betrixaban, a direct inhibitor of factor Xa, shows similar efficacy and safety compared to enoxaparin. However, while it is very promising, oral anticoagulant phase III studies and post-marketing registers are lacking. Moreover, betrixaban has a long half-life, an excretion in the gut by means of P-glycoprotein, and the lack of an antidote. These characteristics and the meta-analysis results prompt us to answer no to the extended thromboprophylaxis in hospitalized medical patients, at least now.

PMID- 29594817 TI - Highlights from the scientific and educational abstracts presented at the ASER 2017 annual scientific meeting and postgraduate course. AB - The annual meeting of the American Society of Emergency Radiology (ASER) took place in Toronto, Canada, on September 6 through September 9, 2017. Attendees represented the USA as well as international emergency radiology communities, including those from academic, private practice, and teleradiology settings. There were several "members in training" in attendance as well. The meeting again featured the "Trauma Head to Toe" 2-day didactic course, highlighting various important topics on imaging of traumatic injuries. Scattered throughout the 4 days were several poster and case of the day presentations, scientific sessions, and self-assessment modules. The following is a summary of the educational posters and scientific papers. PMID- 29594818 TI - Improved peroxidase mimetic activity of a mixture of WS2 nanosheets and silver nanoclusters for chemiluminescent quantification of H2O2 and glucose. AB - It is reported that a mixture of WS2 nanosheets (WS2 NS) and silver nanoclusters (AgNCs) displays strongly enhanced peroxidase-mimicking activity. The catalytic effect of the mixture was studied by colorimetry, fluorometry, chemiluminescence (CL) and electrochemistry. The effect is interpreted in terms of a difference between the Fermi energy level of the two nanomaterials. This leads to the formation of charge separation regions which act as active sites for enzyme mimetic interaction with the substrates. The mixture of WS2 NS and AgNCs was exploited for the non-enzymatic determination of H2O2 and glucose. A stopped-flow method was applied as a sensitive CL detection system using the bicarbonate-H2O2 reaction. The mixture has a powerful peroxidase mimicking activity on the bicarbonate-H2O2 CL reaction, and this effect is much larger than that of any single constituent. In addition, the CL emission is improved several times by using the stopped-flow technique. Under optimum condition, H2O2 can be determined in the 2.5-1500 nM concentration range. Moreover, glucose levels in human serum can be quantified via glucose oxidase based oxidation which leads to the generation of H2O2. Using this CL assay, a linear relationship was obtained between the intensity of the CL emission and glucose concentration in the range of 0.03-20 MUM, with a limit of detection (3S) of 13 nM. Graphical abstract An enhanced peroxidase-like catalytic activity for WS2 nanosheets (WS2 NS) was revealed in the presence of silver nanoclusters (AgNCs), and was exploited for the non-enzymatic determination of H2O2, and of glucose (via glucose oxidase; GOx) using a stopped-flow CL method. PMID- 29594819 TI - Prospective evaluation of serum IL-16 and risk of prostate cancer in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. AB - BACKGROUND: Sexually transmitted infections and chronic inflammation have been associated with an increased risk of prostate cancer. Inflammatory mediators, such as cytokines and free radicals, have been hypothesized to play a role. METHODS: To explore the role of inflammation in prostate cancer risk further, we examined the association between pre-diagnostic serum levels of interleukin-16 (IL-16), an important pleiotropic cytokine, and prostate cancer risk among 932 Caucasian cases and 942 controls and 154 African-American cases and 302 controls in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Serum IL 16 was quantified using enzyme-linked immunoassay. Logistic regression was used to estimate associations between IL-16 and prostate cancer risk, separately by race. RESULTS: Although no association between IL-16 and prostate cancer overall was observed among Caucasians (p = 0.27), a significantly increased risk of high grade prostate cancer, defined as Gleason >= 7 (phet = 0.02), was observed with increasing levels of IL-16 (OR3rd vs. 1st tertile = 1.37, 95% CI 1.04-1.81, ptrend = 0.02). We also discovered a significant interaction between IL-16 and history of gonorrhea (p = 0.04). Among Caucasian men with a history of gonorrhea, elevated IL-16 levels were associated with an increased risk of prostate cancer (OR3rd vs. 1st tertile = 3.64, 95% CI 1.14-11.6) but no association was seen among those without a history of gonorrhea (OR3rd vs. 1st tertile = 1.06, 95% CI 0.83-1.34). No associations were observed among African-Americans. CONCLUSIONS: This study found evidence that higher pre-diagnostic IL-16 levels may be associated with increased risk of high-grade disease, supporting inflammation as potential mechanism by which sexually transmitted diseases may increase risk. PMID- 29594820 TI - Prospective multicenter non-randomized controlled study on intraosseous stability and healing period for dental implants in the posterior region. AB - BACKGROUND: A current implant body surface was treated with "rough processing" by sandblasting and acid etching for the purposes of obtaining more reliable osseointegration and shortening the treatment period. Various reports have examined the healing period with the use of these implant bodies, but a consensus opinion has not yet been obtained. The purpose of this study is to evaluate the relationship between insertion torque (IT) and implant stability quotient (ISQ) at implant treatment using the current rough-surfaced implant. We evaluated the implant treatment sites with ISQ values, IT values, and voxel values. METHODS: Participants in this study comprised 26 patients (10 males, 16 females; mean age, 55.5 years) who received posterior region dental implants at Tokyo Dental College Hospital or Fukuoka Dental College Hospital. For all participants, pretreatment computed tomography and determination of bone quality from voxel values were performed. Thirty-two implant bodies were inserted into the posterior region, and insertion torque was measured. ISQ was also measured at 0, 2, 4, 6, 8, and 12 weeks postoperatively. RESULTS: Eight implant bodies in the maxilla and 24 in the mandible were inserted. All ISQ values increased, exceeding 60 by 6 weeks postoperatively. For insertion torque < 30 N cm, ISQ increased significantly after 8 weeks. For >= 30 N cm, the ratio at which high ISQ values appeared increased significantly after 6 weeks. Compared with the treatment area with insertion torque < 40 N cm, the treatment area >= 40 N cm showed a significantly higher voxel value. CONCLUSIONS: No significant relationship was found between the insertion torque value and the ISQ value. Also, it was suggested that the ISQ value was considered to be an important indicator for observing the treatment state of the implant. PMID- 29594821 TI - Tree nut, peanut, and peanut butter consumption and the risk of gastric and esophageal cancer subtypes: the Netherlands Cohort Study. AB - BACKGROUND: Nut consumption has been associated with reduced cancer-related mortality. However, it is unclear whether nut consumption also reduces the risk of esophageal and gastric cancer subtypes. We prospectively investigated the relationship of tree nut, peanut, and peanut butter intake with risk of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), gastric cardia adenocarcinoma (GCA), and gastric non-cardia adenocarcinoma (GNCA) in the Netherlands Cohort Study. METHODS: In 1986, 120,852 males and females, aged 55-69 years, completed a baseline questionnaire on diet and cancer risk factors. After 20.3 years of follow-up, 133 ESCC, 200 EAC, 191 GCA, and 586 GNCA cases, and 3,720 subcohort members were available for multivariable Cox regression analyses, using a case-cohort approach. RESULTS: Increased total nut consumption was significantly associated with a decreased risk of ESCC and GNCA [HRs (95% CIs) for 10 + g/day vs. nonconsumers = 0.54 (0.30-0.96) and 0.73 (0.55 0.97), respectively], but not with EAC and GCA risk. Similar trends were observed for tree nut and peanut intake, which were mostly nonsignificant. For peanut butter intake, no significant associations were found. When excluding the first four years of follow-up to reduce the possible influence of reversed causation, the relation between nut consumption and ESCC risk attenuated, but remained inverse. CONCLUSIONS: Our findings suggest that increased tree nut and peanut consumption is inversely associated with GNCA risk and possibly with ESCC risk, but not with the risk of the other esophageal and gastric cancer subtypes.

Previous analysis of immune signatures in a cohort of centenarian offspring showed an intermediate immunophenotype between age-matched and younger controls. AIMS: To confirm and extend the previous studies performing further phenotypical analysis in centenarian offspring and controls. METHODS: Analysis of Treg cells, gammadelta T cells, mucosal-associated invariant T cells, and senescent immune T cells was performed in centenarian offspring and controls. RESULTS: We report significant differences between elderly and centenarian offspring in most of the studied subsets, showing that centenarian offspring subsets present an intermediate phenotyping between elderly and younger people. CONCLUSION: The whole present data confirm and extend the previous results showing that centenarian offspring retain more youthful immunological parameters and that the exhaustion of the immune system is less evident than in elderly without centenarian parents, though further investigations are warranted. PMID- 29594823 TI - Estimation of reduced walking speed using simple measurements of physical and psychophysiological function in community-dwelling elderly people: a cross sectional and longitudinal study. AB - BACKGROUND: Early detection of reduced mobility function is important in elderly people. Usual walking speed is useful to assess mobility function, but is often not feasible in a community setting. AIMS: This study aimed to explore a simple surrogate indicator of usual walking speed in elderly people. METHODS: The participants were 516 community-dwelling elderly people. As a baseline survey, the usual walking speed and candidates of surrogate indicators including physical function and psychophysiological function were measured. After 2 years, the occurrence of mobility limitation was assessed. RESULTS: In cross-sectional analysis, a linear regression model with maximum step length, age, and sex presented the most favourable adjusted R2 of 0.426 for estimating usual walking speed. Maximum step length (MSL) also showed good predictive accuracy for usual walking speed < 0.8 m/s {area under the curve [AUC] 0.908 [95% confidence interval (CI) 0.811, 1.000]} and < 1.0 m/s [AUC 0.883 (95% CI) 0.832, 0.933)] in receiver-operating characteristic (ROC) analysis. In longitudinal analysis, the predictive accuracy of MSL for mobility limitation [AUC 0.813 (95% CI 0.752, 0.874)] was similar to that of usual walking speed [AUC 0.808 (95% CI 0.747, 0.869)] in ROC analysis. CONCLUSIONS AND DISCUSSION: The results of this study suggest that MSL may serve as a simple surrogate indicator of UWS in elderly people.

AB - Gillespie's direct method for stochastic simulation of chemical kinetics is a staple of computational systems biology research. However, the algorithm requires explicit enumeration of all reactions and all chemical species that may arise in the system. In many cases, this is not feasible due to the combinatorial explosion of reactions and species in biological networks. Rule-based modeling frameworks provide a way to exactly represent networks containing such combinatorial complexity, and generalizations of Gillespie's direct method have been developed as simulation engines for rule-based modeling languages. Here, we provide both a high-level description of the algorithms underlying the simulation engines, termed network-free simulation algorithms, and how they have been applied in systems biology research. We also define a generic rule-based modeling framework and describe a number of technical details required for adapting Gillespie's direct method for network-free simulation. Finally, we briefly discuss potential avenues for advancing network-free simulation and the role they continue to play in modeling dynamical systems in biology.

AB - An important part the absorption, distribution, metabolism and excretion of an oral therapeutic is the flux rate of drug compound crossing the mucus lining of the gut. To understand this part of the absorption process, we develop a mathematical model of advection, diffusion and binding of drug compounds within the mucus layer of the intestines. Analysis of this model yields simple, measurable criteria for the successful mucin layer traversal of drug compound.

AB - The aim of this study was to compare the effects of Manual Dynamic Agitation and Passive Ultrasonic Irrigation on sodium hypochlorite (NaOCl) penetration into dentinal tubules using its bleaching ability. Thirty-four single-rooted teeth with round-shaped root canals were distributed in two homogeneous groups and one control group, characterized by different NaOCl activation systems: Manual Dynamic Agitation and Passive Ultrasonic Irrigation. After instrumentation, all root canals were stained with 10% copper sulphate solution followed by 1% rubeanic acid alcohol solution under vacuum. Final irrigation was performed with 5 mL of 5.25% NaOCl solution for 1 min and activated with Manual Dynamic Agitation or Passive Ultrasonic Irrigation for another 1 min depending on the treatment group. The teeth were transversely sectioned at the middle portion of the apical, middle, and coronal thirds and observed under light microscope. NaOCl solution penetration was evaluated by measuring the percentage of bleached circumference of the root canal relative to the stained circumference, bleached areas, mean, and maximum penetration depth. No differences in the evaluated parameters were observed between groups (p > 0.05). Within groups, an increase of values was recorded from apical to coronal direction as for percentage of staining, percentage of bleaching and bleached area. NaOCl penetration into dentinal tubules did not significantly vary among the three levels. No significant differences in penetration of sodium hypochlorite into dentinal tubules when activated by means of Manual Dynamic Agitation or Passive Ultrasonic Irrigation were observed in the apical, middle, and coronal thirds of teeth with single straight round root canals.

AB - The aim of this study was to investigate potential cellular responses and biological effects of new generation dental composites on cortical neuron cells in two different exposure times. The study group included five different bulk fill flow able composites; Surefil SDR Flow, X-tra Base Flow, Venus Bulk Flow, Filtek Bulk Flow and Tetric-Evo Flow. They were filled in Teflon molds (Height: 4 mm, Width: 6 mm) and irradiated for 20 s. Cortical neuron cells were inoculated into 24-well plates. After 80% of the wells were coated, the 3 um membrane was inserted and dental filling materials were added. The experiment was continued for 24 and 72 h. Cell viability measured by MTT assay test, total antioxidant and total oxidant status were examined using real assay diagnostic kits. The patterns of cell death (apoptosis) were analyzed using annexin V-FITC staining with flow cytometry. Beta-defensins were quantitatively assessed by RT-PCR. IL-6, IL-8 and IL-10 cytokines were measured from the supernatants. All composites significantly affected analyses parameters during the exposure durations. Our data provide evidence that all dental materials tested are cytotoxic in acute phase and these effects are induced cellular death after different exposure periods. Significant cytotoxicity was detected in TE, XB, SS, FBF and VBF groups at 24 and 72 h, respectively.

AB - This paper describes the preparation of zwitterion-functionalized polymer microspheres (ZPMs) and their application to simultaneous enrichment of V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II) from environmental water samples. The ZPMs were prepared by emulsion copolymerization of ethyl methacrylate, 2 diethylaminoethyl methacrylate and triethylene glycol dimethyl acrylate followed by modification with 1,3-propanesultone. The components were analyzed by elemental analyses as well as Fourier transform infrared spectroscopy, and the structures were characterized by scanning electron microscopy and transmission electron microscopy. The ZPMs were packed into a mini-column for on-line solid phase extraction (SPE) of the above metal ions. Following extraction with 40 mM NH4NO3 and 0.5 M HNO3 solution, the ions were quantified by ICP-MS. Under the optimized conditions, the enrichment factors (from a 40 mL sample) are up to 60 for the ions V(V), As(III), Sb(III) and Hg(II), and 55 for Cr(III) and Sn(IV). The detection limits are 1.2, 3.4, 1.0, 3.7, 2.1 and 1.6 ng L-1 for V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II), respectively, and the relative standard deviations (RSDs) are below 5.2%. The feasibility and accuracy of the method were validated by successfully analyzing six certified reference materials as well as lake, well and river waters. Graphical abstract Zwitterion functionalized polymer microspheres (ZPMs) were prepared and packed into a mini column for on-line solid-phase extraction (SPE) via pump 1. Then V(V), Cr(III), As(III), Sn(IV), Sb(III) and Hg(II) ions in environmental waters were eluted and submitted to ICP-MS via pump 2. PMID- 29594829 TI - Autism spectrum disorders are prevalent among patients with dystrophinopathies. AB - Recent studies have reported a higher prevalence of autism spectrum disorders among patients with dystrophinopathies. The aim of this study was to investigate the prevalence of autism spectrum disorder (ASD) among those with dystrophinopathies. The possible role of dystrophin isoforms in patients was also explored. Fifty-six patients recruited from Toneyama National Hospital were included in this study (mean age = 12.9 years, SD = 5.2 years). Autistic symptoms were evaluated using the Pervasive Developmental Disorders/Autism Spectrum Disorders Rating Scale (PARS), a clinician rating scale. Eleven patients (19.6%; 95% confidence interval 10.2-32.4) met the criteria for ASD based on their PARS scores. Patients were separated into two groups based on the cumulative loss of dystrophin isoforms predicted from the mutation location. The prevalence of ASD was examined between these groups. Infantile and current autistic symptoms did not differ between the groups, except on one subscale of the PARS. This study revealed that there was a high prevalence of ASD in patients with dystrophinopathies. PMID- 29594830 TI - The effects of Vibro-medical insole on vibrotactile sensation in diabetic patients with mild-to-moderate peripheral neuropathy. AB - Peripheral sensory neuropathy seems to be the main risk factor for diabetic foot ulceration. Previous studies demonstrated that stochastic resonance can improve the vibrotactile sensation of diabetic patients. The aim of this study was to evaluate the effects of Vibro-medical insole on pressure and vibration sensation in diabetic patients with mild-to-moderate peripheral neuropathy. A total of 20 patients with mild-to-moderate diabetic neuropathy were included in the pre-test and post-test clinical trial study. Vibro-medical insole consists of medical insole and vibratory system. Medical insole was made independently for each participant and vibratory system was inserted in it. Pressure and vibration sensation were evaluated before and after 30-min walking with Vibro-medical insole. Semmes-Weinstein monofilaments and tuning fork were used to evaluate pressure and vibration sensation, respectively. Pressure sensation showed significantly improvement using Vibro-medical insole at the heel, first and fifth metatarsophalangeal heads, and hallux of both feet in all participants (p < 0.001). Vibration sensation also improved at the big toe of both feet with 256 Hz tuning fork (p < 0.05) but no statistically significant effect was found with 128 Hz tuning fork (p > 0.05). Vibro-medical insole significantly improved pressure and vibration sensation of the foot in diabetic patients with mild-to-moderate peripheral neuropathy. The results suggest that Vibro-medical insole can be used for daily living activities to overcome sensory loss in diabetic neuropathy patients.

AB - On 30th March 1902 Police Constable George Doyle and Carnarvon Station manager Albert Dahlke were allegedly gunned down at Lethbridge's Pocket in Central Queensland. Approximately 90 kg of ash and burnt human remains with articles belonging to the two men were later found in saddle bags left at the scene on a police horse. Subsequently two local cattle and horse thieves, Patrick and James Kenniff, were convicted in the Queensland Supreme Court of the wilful murder of Constable Doyle. Patrick was executed by hanging on 12th January 1903 and James had his sentence reduced to life imprisonment with hard labor. A number of irregularities were subsequently raised about the trial including the use of a "special" jury and the reliability of evidence from a witness who did not actually see the event. Forensic issues to be explored involve the accuracy of the descriptions of the carbonized material, whether the remains were actually those of Doyle and Dahlke, and whether the victims were dismembered before burning, as was alleged by the prosecution. PMID- 29594831 TI - Neurology and the Internet: a review. AB - Nowadays, the Internet is the major source to obtain information about diseases and their treatments. The Internet is gaining relevance in the neurological setting, considering the possibility of timely social interaction, contributing to general public awareness on otherwise less-well-known neurological conditions, promoting health equity and improving the health-related coping. Neurological patients can easily find several online opportunities for peer interactions and learning. On the other hand, neurologist can analyze user-generated data to better understand patient needs and to run epidemiological studies. Indeed, analyses of queries from Internet search engines on certain neurological diseases have shown a strict temporal and spatial correlation with the "real world." In this narrative review, we will discuss how the Internet is radically affecting the healthcare of people with neurological disorders and, most importantly, is shifting the paradigm of care from the hands of those who deliver care, into the hands of those who receive it. Besides, we will review possible limitations, such as safety concerns, financial issues, and the need for easy-to-access platforms. PMID- 29594833 TI - Palatal Polymorphous Adenocarcinoma with High-Grade Transformation: A Case Report and Literature Review. AB - Polymorphous adenocarcinoma (PAC) is the second most common intraoral malignant neoplasm of the minor salivary glands. However, it is very rare for PAC to show high-grade transformation (HGT) and to our knowledge, the English literature only seven reported cases. HGT tends to be observed when PAC recurs, and it is extremely rare to be seen at initial presentation. Here we report a 43-year-old Japanese male patient with PAC of the right palate showing HGT at initial presentation. Histopathologically, the tumor was characterized by a prominent solid and papillary-cystic growth pattern, with nuclear atypia and necrosis in area of HGT. The immunohistochemical staining pattern was consistent with PAC, as the tumor cells showed diffuse positivity for cytokeratin, vimentin and S-100, and focal positivity for bcl-2, alpha-SMA and EMA. The tumor cells in HGT areas were markedly positive for AR and Ki-67 (about 40%/HPF), and also focally positive for cyclin D1 and p53, whereas HER2/neu, ER, PgR, p63, D2-40, GCDFP-15, and mitochondria were negative. Here we present a very rare case of palatal PAC with HGT at initial presentation.

AB - Ciprofloxacin (CIP) antibiotic is considered as an emerging and biological resistant pollutant. This study aimed to improve of the removal of CIP from synthetic aqueous solutions in photocatalytic process through copper oxide nanoparticles as catalyst (CuO/UV). The effect of CIP concentration (10-200 mg/l), catalyst dosage included CuO (0.01-0.1 g/l) and pH (3-11) as independent variables on the COD removal efficiency as response in photocatalytic process using UV-C lamps with three different powers of 8, 15 and 30-W were optimized through the central composite design in response surface method using design expert software. A second order model was selected as the best model with R2 values and lack of fit as 0.85 and 0.06 for lamp 8-W, 0.89 and 0.11 for lamp 15 W, and 0.86 and 0.19 for lamp 30-W, respectively. Optimum conditions were obtained in CIP concentration of 11.2 (mg/l), CuO dosage of 0.08 (g/l), and pH value of 8.17. In this condition, predicted maximum COD removal was respectively found 83.79, 93.18, and 98.90% for lamps 8, 15 and 30-W. According to the results, photocatalytic process using copper oxide nanoparticles can effectively compose CIP in aqueous solutions. PMID- 29594835 TI - Cu x O@DNA sphere-based electrochemical bioassay for sensitive detection of Pb2. AB - The paper describes a one-step synthetic method to chemically reduce cupric sulfate by ascorbic acid in the presence of DNA strands to directly produce Cu x O@DNA spheres. The DNA strands act as template to assist the preparation of Cu x O, and also are capable of specifically binding Pb(II) ions. The Cu x O@DNA spheres possess high specific surface area and strong bioaffinity. They can be directly employed as platform for detecting Pb2+ sensitively. Electrochemical impedance spectroscopy data showed that the assay exhibits high sensitivity and a wide linear analytical range that extends from 0.1 to 100 nM, and the detection limit is 6.8 pM at a signal-to-noise ratio of 3. The assay is selective, acceptably reproducible, stable, and well feasible for the detection of Pb2+ in blood serum. Graphical abstract Schematic presentation of the preparation of DNA templated Cu x O spheres (Cu x O@DNA) for use in electrochemical detection of Pb2+. The assay exhibits detection limit of 6.8 pM, high selectivity, acceptable reproducibility, stability, and good applicability for Pb2+ detection.

AB - Aicardi-Goutieres syndrome, a rare genetic disorder characterized by calcification of basal ganglia, results in psychomotor delays and epilepsy states from the early months of children life. This disease is caused by mutations in seven different genes encoding proteins implicated in the metabolism of nucleic acids, including SAMHD1. Twenty SAMHD1 gene variants have been discovered and in this work, a structural characterization of the SAMHD1 Aicardi-Goutieres Arg145Gln mutant is reported by classical molecular dynamics simulation. Four simulations have been carried out and compared. Two concerning the wild-type SAMHD1 form in presence and absence of cofactors, in order to explain the role of cofactors in the SAMHD1 assembly/disassembly process and, two concerning the Arg145Gln mutant, also in presence and absence of cofactors, in order to have an accurate comparison with the corresponding native forms. Results show the importance of native residue Arg145 in maintaining the tetramer, interacting with GTP cofactor inside allosteric sites. Replacement of arginine in glutamine gives rise to a loosening of GTP-protein interactions, when cofactors are present in allosteric sites, whilst in absence of cofactors, the occurrence of intra and inter-chain interactions is observed in the mutant, not seen in the native enzyme, making energetically unfavourable the tetramerization process. PMID- 29594837 TI - Diagnosing pituitary adenoma in unstained sections based on multiphoton microscopy. AB - PURPOSE: If we can find a new method that can achieve rapid diagnosis of adenoma during operation, it will help surgeon shorten the operation time and enhance the treatment efficacy. This study discusses the feasibility of multiphoton microscopy (MPM) in diagnosing pituitary adenoma. METHOD: MPM, based on two photon excited fluorescence (TPEF) and second harmonic generation (SHG) is performed for the diagnosis of pituitary adenoma in unstained sections. RESULTS: Our results show that MPM can reveal the variation of reticulin fiber by SHG signals of collagen, combined with the measurement of area of acinus, thickness of collagen fiber and collagen percentage. MPM can further reflect the change of meshwork in normal pituitary and hyperplasia quantitatively. And the characteristics of typical growth patterns of pituitary adenoma are demonstrated by the overlay of SHG and TPEF images. What's more, we can identify the boundary of normal pituitary, hyperplasia and adenoma from MPM images. And the experiment also results verify the feasibility of this method in frozen sections. CONCLUSION: These results indicated that MPM can make a diagnosis of pituitary adenoma by the morphological changes without routine pathological processing including hematoxylin-eosin (H&E) staining and other special staining. Therefore, this technique is expected to help diagnosis of pituitary adenoma during operation. PMID- 29594838 TI - The relation between retrobulbar blood flow and posterior ocular changes measured using spectral-domain optical coherence tomography in patients with obstructive sleep apnea syndrome. AB - PURPOSE: To investigate the effect of posterior ocular hemodynamics on the retinal nerve fiber layer (RNFL), choroid thickness (CT) and central macular thickness (CMT) in patients with obstructive sleep apnea syndrome (OSAS) and to reveal the association with glaucomatous optic neuropathy. METHODS: The research was planned as a prospective, randomized study. The ophthalmic, retinal and posterior ciliary artery pulsatile index (PI) and resistive index (RI) were measured by colored Doppler sonography. RNFL thickness, CMT and CT were then measured by spectral-domain optical coherence tomography. RESULTS: Sixty subjects were divided into four groups-mild, moderate and severe OSAS and a control group. There were 16 subjects in the control group, 14 in the mild OSAS group, 15 in the moderate OSAS group and 15 in the severe OSAS group. Ophthalmic artery and central retinal artery PI and RI values of the OSAS patients did not show statistically significant difference than those of the control group, but posterior ciliary artery (PCA) PI and RI values were significantly higher. In addition, mean, superior and inferior RNFL thickness values were significantly lower than those in the control group. Moreover, the glaucoma prevalence of the OSAS patients in this study was 6.8% and all of these patients were in the severe OSAS group. CONCLUSION: PI and RI values of the PCA, which supplies the optic nerve, show a linear increase as the apnea hypoxia index values in OSAS. As the grade of OSAS improves, this situation leads to a more serious ischemic optic neuropathy. Furthermore, the prevalence of glaucoma in this study is found to be higher in the severe OSAS group.

AB - Five isocoumarin derivatives including three new compounds, aspergisocoumrins A-C (1-3), together with two known analogues, 8-dihydroxyisocoumarin-3-carboxylic acid (4) and dichlorodiaportin (5) were obtained from the culture of the endophytic fungus Aspergillus sp. HN15-5D derived from the fresh leaves of the mangrove plant Acanthus ilicifolius. Their structures were elucidated using comprehensive spectroscopic methods. The double bond geometry of compounds 1 and 2 were assigned as E and Z on the basis of the distinct coupling constants, respectively. Compounds 1 and 2 showed cytotoxicity against MDA-MB-435 with IC50 values of 5.08 +/- 0.88 and 4.98 +/- 0.74 MUM, respectively. PMID- 29594841 TI - A two-wavelength fluorescence recovery method for the simultaneous determination of aureomycin and oxytetracycline by using gold nanocrystals modified with serine and 11-mercaptoundecanoic acid. AB - A method is described for rapid (1 h) synthesis of gold nanoclusters (AuNCs) co functionalized with serine and 11-mercaptoundecanoic acid. The co-functionalized AuNCs exhibit good stability towards temperature, pH values, and over time. They were characterized by atomic force microscopy, high-resolution transmission electron microscopy, dynamic light scattering, and by fluorescence, IR and X-ray photoelectron spectroscopies. The fluorescence of the AuNCs is quenched by Hg(II) and restored on subsequent addition of aureomycin (CTC) or oxytetracycline (OTC). A fluorescent turn-on assay was worked out for simultaneous detection of CTC and OTC based on recording the change of the restored fluorescence measured at 420 and 500 nm under 340 nm photoexcitation. The detection limits are 20 and 9 nM for CTC and OTC, respectively. The concentrations of CTC and OTC can also be visualized by UV illumination. The nanoprobe was successfully applied to the simultaneous determination of CTC and OTC in spiked human urine. Graphical abstract Schematic of a two-wavelength fluorescence recovery method for the simultaneous determination of aureomycin and oxytetracycline. It is based on the use of gold nanocrystals modified with serine and 11-mercaptoundecanoic acid, and on recording the change of the restored fluorescence measured at 420 and 500 nm. PMID- 29594839 TI - O-GlcNAc in cancer: An Oncometabolism-fueled vicious cycle. AB - Cancer cells exhibit unregulated growth, altered metabolism, enhanced metastatic potential and altered cell surface glycans. Fueled by oncometabolism and elevated uptake of glucose and glutamine, the hexosamine biosynthetic pathway (HBP) sustains glycosylation in the endomembrane system. In addition, the elevated pools of UDP-GlcNAc drives the O-GlcNAc modification of key targets in the cytoplasm, nucleus and mitochondrion. These targets include transcription factors, kinases, key cytoplasmic enzymes of intermediary metabolism, and electron transport chain complexes. O-GlcNAcylation can thereby alter epigenetics, transcription, signaling, proteostasis, and bioenergetics, key 'hallmarks of cancer'. In this review, we summarize accumulating evidence that many cancer hallmarks are linked to dysregulation of O-GlcNAc cycling on cancer relevant targets. We argue that onconutrient and oncometabolite-fueled elevation increases HBP flux and triggers O-GlcNAcylation of key regulatory enzymes in glycolysis, Kreb's cycle, pentose-phosphate pathway, and the HBP itself. The resulting rerouting of glucose metabolites leads to elevated O-GlcNAcylation of oncogenes and tumor suppressors further escalating elevation in HBP flux creating a 'vicious cycle'. Downstream, elevated O-GlcNAcylation alters DNA repair and cellular stress pathways which influence oncogenesis. The elevated steady-state levels of O-GlcNAcylated targets found in many cancers may also provide these cells with a selective advantage for sustained growth, enhanced metastatic potential, and immune evasion in the tumor microenvironment. PMID- 29594842 TI - Associations between anxiolytic medications and ventral hernia repair. AB - PURPOSE: This study examines the relationship between anxiolytic medications (AXM) on outcomes following ventral hernia repair. METHODS: A single-center review of prospectively obtained perioperative and 30-day outcome data, including AXM use at admission, as part of the National Surgery Quality Improvement Program. RESULTS: Sixty-three of the 393 patients who presented for ventral hernia repair were taking an AXM (15.6%). AXM users were more likely to have a higher ASA class, dyspnea, and treated hypertension (p < 0.05). AXM use was associated with increased operative duration, hernia size, increased estimated blood loss, and need for component separation. After adjusting for medical comorbidities, AXM users were not found to have greater 30-day morbidity or mortality. Patients taking AXM were found to have greater length of stay and increased hospital readmissions. CONCLUSIONS: Patients taking anxiolytic medications undergoing ventral hernia repairs have higher ASA scores, more complex hernia characteristics, and require more concurrent procedures. They were found to have longer operative times, increased blood loss, greater duration of hospital stay, and increased readmissions that were associated with the increased perioperative risk factors. Further studies are required to determine causal links. PMID- 29594843 TI - Molecular cloning, expression, and functional characterization of the beta agarase AgaB-4 from Paenibacillus agarexedens. AB - In this study, a beta-agarase gene, agaB-4, was isolated for the first time from the agar-degrading bacterium Paenibacillus agarexedens BCRC 17346 by using next generation sequencing. agaB-4 consists of 2652 bp and encodes an 883-amino acid protein with an 18-amino acid signal peptide. agaB-4 without the signal peptide DNA was cloned and expressed in Escherichia coli BL21(DE3). His-tagged recombinant AgaB-4 (rAgaB-4) was purified from the soluble fraction of E. coli cell lysate through immobilized metal ion affinity chromatography. The optimal temperature and pH of rAgaB-4 were 55 degrees C and 6.0, respectively. The results of a substrate specificity test showed that rAgaB-4 could degrade agar, high-melting point agarose, and low-melting point agarose. The Vmax and Km of rAgaB-4 for low-melting point agarose were 183.45 U/mg and 3.60 mg/mL versus 874.61 U/mg and 9.29 mg/mL for high-melting point agarose, respectively. The main products of agar and agarose hydrolysis by rAgaB-4 were confirmed to be neoagarotetraose. Purified rAgaB-4 can be used in the recovery of DNA from agarose gels and has potential application in agar degradation for the production of neoagarotetraose. PMID- 29594844 TI - Host-parasite association between Didelphis albiventris (Didelphimorphia: Didelphidae) and Ixodes loricatus (Acari: Ixodidae) in their southern ranges. AB - The parasitism of Ixodes loricatus Neumann on white-eared opposum, Didelphis albiventris Lund, was analysed in the southern ranges of both. In central Argentina, 118 wild opossums were captured from 2005 to 2012. Adults of I. loricatus were collected (prevalence = 66.1%, mean = 7.03, median = 4), but no immature stage. Tick infestation was not affected by sex (p = 0.27) or age (p = 0.37) of hosts. In line with previous studies about seasonality of larvae and nymphs of I. loricatus, adult tick infestation showed no seasonal trend. This lack of seasonal pattern of infestation for all parasitic stages of I. loricatus may indicate a life cycle governed by nidicolous behaviour, in such a way that this habit would contribute to minimize the influence of external environmental variables. The tick sex ratio was female biased, with two females per one male (p = 0.002). The absence of I. loricatus immatures on D. albiventris suggests that in the study region there is clear segregation of immatures in rodents and adults in marsupials. PMID- 29594845 TI - Efficacy of carbon dioxide treatments for the control of the two-spotted spider mite, Tetranychus urticae, and treatment impact on plant seedlings. AB - To develop a new control method for the two-spotted spider mite (TSSM), Tetranychus urticae, we investigated the effect of controlled atmospheres of carbon dioxide (CO2) on TSSM mortality under different concentrations and treatment periods, and evaluated the impact of treatments on seedlings of five host plants of TSSM. Egg hatching rate of TSSM was reduced to 37.7, 5.4 or 0% after 24 h treatment involving concentrations of 16.7, 33.3 or 50%, respectively. Mobile stages (nymphs and adult) of TSSM were completely controlled after 24 h treatment at concentrations higher than 33.3%. After 4 h at concentrations of 33.3 or 50%, 1st-day survival rate for all mobile stages was 45.3 or 36.0%, respectively, whereas after 8 or 16 h treatments, all values were decreased to zero. Seedlings of four major host plants of TSSM (cucumber, eggplant, rape, green peppers) were damaged to varying degrees after 24 h at the three concentrations, but strawberry, another host plant, was not damaged. Cucumber suffered the most serious damage, resulting in wilting and death. In conclusion, controlled atmospheres of CO2 can kill TSSM, particularly at high concentrations and with long treatment times. It can be used to control TSSM on strawberry, but should be used cautiously on other host plants.

AB - Kyasanur forest disease (KFD) is a major tick-borne viral haemorrhagic fever caused by KFD virus (KFDV) (Flaviviridae). The disease was reported to be confined to five districts of Karnataka state India until 2011. During 2012-2016, emergence of KFD has been reported in newer areas of Karnataka and adjoining states. Therefore, survey of tick vectors was carried out in these new areas of Karnataka and adjoining states reported with monkey deaths and human cases of KFD. In all selected sites, ticks from the forest floor were collected by lint clothes using flagging method. Tick samples were tested for KFDV nucleic acid by real-time RT-PCR. A total of 4772 ticks, comprising eight species of genus Haemaphysalis and one species each of genus Amblyomma, Ixodes and Rhipicephalus was collected. Haemaphysalis spinigera, the principal vector of KFDV was the predominant tick species (59.5%) collected followed by H. turturis (8.6%). The abundance of H. spinigera ranged from 9.2 to 33.9 per man-hour in the six districts surveyed. Of 214 (4418 tick samples) pools screened by real-time RT PCR, two pools of H. spinigera were positive for KFDV. High abundance of Haemaphysalis vectors in the six districts indicated that the districts are receptive for KFD outbreaks. KFDV was detected in the tick vectors in the new foci of the KFD. Data on tick distribution will be useful in creating KFD risk map for strengthening the ongoing preventive measures such as vaccination and supply of insect repellents to the high risk groups and intensive health education. PMID- 29594847 TI - The combination of cardiorespiratory fitness and muscle strength, and mortality risk. AB - Little is known about the combined associations of cardiorespiratory fitness (CRF) and hand grip strength (GS) with mortality in general adult populations. The purpose of this study was to compare the relative risk of mortality for CRF, GS, and their combination. In UK Biobank, a prospective cohort of > 0.5 million adults aged 40-69 years, CRF was measured through submaximal bike tests; GS was measured using a hand-dynamometer. This analysis is based on data from 70,913 men and women (832 all-cause, 177 cardiovascular and 503 cancer deaths over 5.7-year follow-up) who provided valid CRF and GS data, and with no history of heart attack/stroke/cancer at baseline. Compared with the lowest CRF category, the hazard ratio (HR) for all-cause mortality was 0.76 [95% confidence interval (CI) 0.64-0.89] and 0.65 (95% CI 0.55-0.78) for the middle and highest CRF categories, respectively, after adjustment for confounders and GS. The highest GS category had an HR of 0.79 (95% CI 0.66-0.95) for all-cause mortality compared with the lowest, after adjustment for confounders and CRF. Similar results were found for cardiovascular and cancer mortality. The HRs for the combination of highest CRF and GS were 0.53 (95% CI 0.39-0.72) for all-cause mortality and 0.31 (95% CI 0.14 0.67) for cardiovascular mortality, compared with the reference category of lowest CRF and GS: no significant association for cancer mortality (HR 0.70; 95% CI 0.48-1.02). CRF and GS are both independent predictors of mortality. Improving both CRF and muscle strength, as opposed to either of the two alone, may be the most effective behavioral strategy to reduce all-cause and cardiovascular mortality risk.

AB - Hollow carbon dots (HCDs) were prepared by a solvothermal method and conjugated to either tetramethyl rhodamine isothiocyanate (TRITC) or fluorescein-5 isothiocyanate (FITC). This resulted in HCDs with bright red or green fluorescence, with excitation/emission peaks at 550/580 and 491/520 nm, respectively. The nanocomposites are well water-soluble, remarkably photostable and biocompatible. In addition, the fluorescence of the composites is more stable in a reactive oxygen environment than the free dyes. Confocal images indicate that the nanoparticles quickly enter A549 cells and mainly accumulate in the cytoplasm. The wavelength of functionalized HCDs can be regulating via coupling the HCDs to different dyes. These results demonstrate that these composite materials can be very promising reagents for biological labeling and imaging. Graphical abstract Schematic of the preparation of hollow carbon dots conjugated to tetramethyl rhodamine isothiocyanate (RHCDs) by solvothermal method. The material is water-soluble, remarkably photostable and biocompatible. It was applied to cellular labeling and imaging. PMID- 29594849 TI - Letter from the new Editor-in-Chief for Insights into Imaging. PMID- 29594851 TI - Endocavitary contrast enhanced ultrasound (CEUS): a novel problem solving technique. AB - : Contrast-enhanced ultrasound (CEUS) is a technique that has developed as an adjunct to conventional ultrasound. CEUS offers a number of benefits over conventional axial imaging with computerised tomography and magnetic resonance imaging, primarily as a "beside" test, without ionising radiation or the safety concerns associated with iodinated/gadolinium-based contrast agents. Intravascular use of ultrasound contrast agents (UCAs) is widespread with extensive evidence for effective use. Despite this, the potential utility of UCAs in physiological and non-physiological cavities has not been fully explored. The possibilities for endocavitary uses of CEUS are described in this review based on a single-centre experience including CEUS technique and utility in confirming drain placement, as well as within the biliary system, urinary system, gastrointestinal tract and intravascular catheters. TEACHING POINTS: * CEUS offers an excellent safety profile, spatial resolution and is radiation free. * Endocavitary CEUS provides real-time imaging similar to fluoroscopy in a portable setting. * Endocavitary CEUS can define internal architecture of physiological cavities. * Endocavitary CEUS can confirm drain position in physiological and non physiological cavities. PMID- 29594852 TI - Information architecture for a patient-specific dashboard in head and neck tumor boards. AB - PURPOSE: Overcoming the flaws of current data management conditions in head and neck oncology could enable integrated information systems specifically tailored to the needs of medical experts in a tumor board meeting. Clinical dashboards are a promising method to assist various aspects of the decision-making process in such cognitively demanding scenarios. However, in order to provide extensive and intuitive assistance to the participating physicians, the design and development of such a system have to be user-centric. To accomplish this task, conceptual methods need to be performed prior to the technical development and integration stages. METHODS: We have conducted a qualitative survey including eight clinical experts with different levels of expertise in the field of head and neck oncology. According to the principles of information architecture, the survey focused on the identification and causal interconnection of necessary metrics for information assessment in the tumor board. RESULTS: Based on the feedback by the clinical experts, we have constructed a detailed map of the required information items for a tumor board dashboard in head and neck oncology. Furthermore, we have identified three distinct groups of metrics (patient, disease and therapy metrics) as well as specific recommendations for their structural and graphical implementation. CONCLUSION: By using the information architecture, we were able to gather valuable feedback about the requirements and cognitive processes of the tumor board members. Those insights have helped us to develop a dashboard application that closely adapts to the specified needs and characteristics, and thus is primarily user-centric. PMID- 29594850 TI - Added value of double reading in diagnostic radiology,a systematic review. AB - OBJECTIVES: Double reading in diagnostic radiology can find discrepancies in the original report, but a systematic program of double reading is resource consuming. There are conflicting opinions on the value of double reading. The purpose of the current study was to perform a systematic review on the value of double reading. METHODS: A systematic review was performed to find studies calculating the rate of misses and overcalls with the aim of establishing the added value of double reading by human observers. RESULTS: The literature search resulted in 1610 hits. After abstract and full-text reading, 46 articles were selected for analysis. The rate of discrepancy varied from 0.4 to 22% depending on study setting. Double reading by a sub-specialist, in general, led to high rates of changed reports. CONCLUSIONS: The systematic review found rather low discrepancy rates. The benefit of double reading must be balanced by the considerable number of working hours a systematic double-reading scheme requires. A more profitable scheme might be to use systematic double reading for selected, high-risk examination types. A second conclusion is that there seems to be a value of sub-specialisation for increased report quality. A consequent implementation of this would have far-reaching organisational effects. KEY POINTS: * In double reading, two or more radiologists read the same images. * A systematic literature review was performed. * The discrepancy rates varied from 0.4 to 22% in various studies. * Double reading by sub-specialists found high discrepancy rates. PMID- 29594853 TI - SUPRA: open-source software-defined ultrasound processing for real-time applications : A 2D and 3D pipeline from beamforming to B-mode. AB - PURPOSE: Research in ultrasound imaging is limited in reproducibility by two factors: First, many existing ultrasound pipelines are protected by intellectual property, rendering exchange of code difficult. Second, most pipelines are implemented in special hardware, resulting in limited flexibility of implemented processing steps on such platforms. METHODS: With SUPRA, we propose an open source pipeline for fully software-defined ultrasound processing for real-time applications to alleviate these problems. Covering all steps from beamforming to output of B-mode images, SUPRA can help improve the reproducibility of results and make modifications to the image acquisition mode accessible to the research community. We evaluate the pipeline qualitatively, quantitatively, and regarding its run time. RESULTS: The pipeline shows image quality comparable to a clinical system and backed by point spread function measurements a comparable resolution. Including all processing stages of a usual ultrasound pipeline, the run-time analysis shows that it can be executed in 2D and 3D on consumer GPUs in real time. CONCLUSIONS: Our software ultrasound pipeline opens up the research in image acquisition. Given access to ultrasound data from early stages (raw channel data, radiofrequency data), it simplifies the development in imaging. Furthermore, it tackles the reproducibility of research results, as code can be shared easily and even be executed without dedicated ultrasound hardware. PMID- 29594854 TI - Blended shared control utilizing online identification : Regulating grasping forces of a surrogate surgical grasper. AB - PURPOSE: Surgical robots are increasingly common, yet routine tasks such as tissue grasping remain potentially harmful with high occurrences of tissue crush injury due to the lack of force feedback from the grasper. This work aims to investigate whether a blended shared control framework which utilizes real-time identification of the object being grasped as part of the feedback may help address the prevalence of tissue crush injury in robotic surgeries. METHODS: This work tests the proposed shared control framework and tissue identification algorithm on a custom surrogate surgical robotic grasping setup. This scheme utilizes identification of the object being grasped as part of the feedback to regulate to a desired force. The blended shared control is arbitrated between human and an implicit force controller based on a computed confidence in the identification of the grasped object. The online identification is performed using least squares based on a nonlinear tissue model. Testing was performed on five silicone tissue surrogates. Twenty grasps were conducted, with half of the grasps performed under manual control and half of the grasps performed with the proposed blended shared control, to test the efficacy of the control scheme. RESULTS: The identification method resulted in an average of 95% accuracy across all time samples of all tissue grasps using a full leave-grasp-out cross validation. There was an average convergence time of [Formula: see text] ms across all training grasps for all tissue surrogates. Additionally, there was a reduction in peak forces induced during grasping for all tissue surrogates when applying blended shared control online. CONCLUSION: The blended shared control using online identification more successfully regulated grasping forces to the desired target force when compared with manual control. The preliminary work on this surrogate setup for surgical grasping merits further investigation on real surgical tools and with real human tissues. PMID- 29594855 TI - The Plasma Membrane Calcium Pump (PMCA): Regulation of Cytosolic Ca2+, Genetic Diversities and Its Role in Sub-plasma Membrane Microdomains. AB - In this chapter the four different genes of the mammalian plasma membrane calcium ATPase (PMCA) and their spliced isoforms are discussed with respect to the structural and functional properties of PMCA, the tissue distribution of the different isoforms, including their differences during development. The importance of PMCA for regulating Ca2+ signaling in microdomains under different conditions is also discussed. PMID- 29594856 TI - Structure-Function Relationship of the Voltage-Gated Calcium Channel Cav1.1 Complex. AB - Voltage-gated calcium (Cav) channels are miniature membrane transistors that convert membrane electrical signals to intracellular Ca2+ transients that trigger many physiological events. In mammals, there are ten subtypes of Cav channel, among which Cav1.1 is the first Cavalpha1 to be cloned. Cav1.1 is specified for the excitation-contraction coupling of skeletal muscles, and has been a prototype in the structural investigations of Cav channels. This article summarized the recent advances in the structural elucidation of Cav1.1 and the mechanistic insights derived from the 3.6 A structure obtained using single-particle, electron cryomicroscopy. The structure of the Cav1.1 complex established the framework for mechanistic understanding of excitation-contraction coupling and provides the template for molecular interpretations of the functions and disease mechanisms of Cav and Nav channels. PMID- 29594857 TI - Structure-Dynamic Coupling Through Ca2+-Binding Regulatory Domains of Mammalian NCX Isoform/Splice Variants. AB - Mammalian Na+/Ca2+ exchangers (NCX1, NCX2, and NCX3) and their splice variants are expressed in a tissue-specific manner and are regulated by Ca2+ binding CBD1 and CBD2 domains. NCX2 does not undergo splicing, whereas in NCX1 and NCX3, the splicing segment (with mutually exclusive and cassette exons) is located in CBD2. Ca2+ binding to CBD1 results in Ca2+-dependent tethering of CBDs through the network of interdomain salt-bridges, which is associated with NCX activation, whereas a slow dissociation of "occluded" Ca2+ inactivates NCX. Although NCX variants share a common structural basis for Ca2+-dependent tethering of CBDs, the Ca2+ off-rates of occluded Ca2+ vary up to 50-fold, depending on the exons assembly. The Ca2+-dependent tethering of CBDs rigidifies the interdomain movements of CBDs without any significant changes in the CBDs' alignment; consequently, more constraining conformational states become more populated in the absence of global conformational changes. Although this Ca2+-dependent "population shift" is a common mechanism among NCX variants, the strength and span of backbone rigidification from the C-terminal of CBD1 to the C-terminal of CBD2 is exon dependent. The mutually exclusive exons differentially stabilize/destabilize the backbone dynamics of Ca2+-bound CBDs in NCX1 and NCX3 variants, whereas the cassette exons control the stability of the interdomain linker. The combined effects of mutually exclusive and cassette exons permit a fine adjustment of two different regulatory pathways: the Ca2+-dependent activation (controlled by CBD1) and the Ca2+-dependent alleviation of Na+-induced inactivation (controlled by CBD2). Exon-controlled dynamic features match with cell-specific regulatory requirements in a given variant. PMID- 29594858 TI - The Endoplasmic Reticulum and the Cellular Reticular Network. AB - The endoplasmic reticulum and the other organelles of the eukaryotic cell are membrane-bound structures that carry out specialized functions. In this chapter, we discuss strategies that the cell has adopted to link and coordinate the different activities occurring within its various organelles as the cell carries out its physiological role. PMID- 29594859 TI - Structure-Function Relationship of the SERCA Pump and Its Regulation by Phospholamban and Sarcolipin. AB - Calcium is a universal second messenger involved in diverse cellular processes, including excitation-contraction coupling in muscle. The contraction and relaxation of cardiac muscle cells are regulated by the cyclic movement of calcium primarily between the extracellular space, the cytoplasm and the sarcoplasmic reticulum (SR). The rapid removal of calcium from the cytosol is primarily facilitated by the sarco(endo)plasmic reticulum calcium ATPase (SERCA) which pumps calcium back into the SR lumen and thereby controls the amount of calcium in the SR. The most studied member of the P-type ATPase family, SERCA has multiple tissue- and cell-specific isoforms and is primarily regulated by two peptides in muscle, phospholamban and sarcolipin. The multifaceted regulation of SERCA via these peptides is exemplified in the biological fine-tuning of their independent oligomerization and regulation. In this chapter, we overview the structure-function relationship of SERCA and its peptide modulators, detailing the regulation of the complexes and summarizing their physiological and disease relevance. PMID- 29594860 TI - Structural Insights into IP3R Function. AB - Inositol 1,4,5-trisphosphate receptors (IP3Rs) are ubiquitously expressed intracellular ligand-gated Ca2+ channels present on the endoplasmic reticulum of virtually all eukaryotic cells. These channels mediate the Ca2+ release from intracellular stores in response to activation by the signaling molecule IP3, which functions to transmit diverse signals received by the cell, e.g. from hormones, neurotransmitters, growth factors and hypertrophic stimuli, to various signaling pathways within the cell. Thus, IP3R channels can be conceptualized as highly dynamic scaffold membrane protein complexes, where binding of ligands can change the scaffold structure leading to cellular Ca2+ signals that direct markedly different cellular actions. Although extensively characterized in physiological and biochemical studies, the detailed mechanisms of how IP3Rs produce highly controlled Ca2+ signals in response to diversified extra- and intracellular stimuli remains unknown and requires high-resolution knowledge of channel molecular architecture. Recently, single-particle electron cryomicroscopy (cryo-EM) has yielded a long-awaited near-atomic resolution structure of the entire full-length type 1 IP3R. This structure provides important insights into the molecular underpinnings of ligand-mediated activation and regulation of IP3R. In this chapter, we evaluate available information and research progress on the structure of IP3R channel in an attempt to shed light on its function. PMID- 29594861 TI - IP3 Receptor Properties and Function at Membrane Contact Sites. AB - The inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) is a ubiquitously expressed Ca2+-release channel localized in the endoplasmic reticulum (ER). The intracellular Ca2+ signals originating from the activation of the IP3R regulate multiple cellular processes including the control of cell death versus cell survival via their action on apoptosis and autophagy. The exact role of the IP3Rs in these two processes does not only depend on their activity, which is modulated by the cytosolic composition (Ca2+, ATP, redox status, ...) and by various types of regulatory proteins, including kinases and phosphatases as well as by a number of oncogenes and tumor suppressors, but also on their intracellular localization, especially at the ER-mitochondrial and ER-lysosomal interfaces. At these interfaces, Ca2+ microdomains are formed, in which the Ca2+ concentration is finely regulated by the different ER, mitochondrial and lysosomal Ca2+-transport systems and also depends on the functional and structural interactions existing between them. In this review, we therefore discuss the most recent insights in the role of Ca2+ signaling in general, and of the IP3R in particular, in the control of basal mitochondrial bioenergetics, apoptosis, and autophagy at the level of inter-organellar contact sites. PMID- 29594862 TI - Structural Details of the Ryanodine Receptor Calcium Release Channel and Its Gating Mechanism. AB - Ryanodine receptors (RyRs) are large intracellular calcium release channels that play a crucial role in coupling excitation to contraction in both cardiac and skeletal muscle cells. In addition, they are expressed in other cell types where their function is less well understood. Hundreds of mutations in the different isoforms of RyR have been associated with inherited myopathies and cardiac arrhythmia disorders. The structure of these important drug targets remained elusive for a long time, despite decades of intensive research. In the recent years, a technical revolution in the field of single particle cryogenic electron microscopy (SP cryo-EM) allowed solving high-resolution structures of the skeletal and cardiac RyR isoforms. Together with the structures of individual domains solved by X-ray crystallography, this resulted in an unprecedented understanding of the structure, gating and regulation of these largest known ion channels. In this chapter we describe the recently solved high-resolution structures of RyRs, discuss molecular details of the channel gating, regulation and the disease mutations. Additionally, we highlight important questions that require further progress in structural studies of RyRs. PMID- 29594863 TI - Store-Operated Calcium Entry: An Historical Overview. AB - Store-operated calcium entry is a mechanism of Ca2+ signaling that has evolved from theory to molecules over a period of 30 years. This brief overview summarizes the major milestones that have led to the current concepts regarding the mechanisms and regulation of this most widely encountered of calcium signaling mechanisms. PMID- 29594864 TI - From Stores to Sinks: Structural Mechanisms of Cytosolic Calcium Regulation. AB - All eukaryotic cells have adapted the use of the calcium ion (Ca2+) as a universal signaling element through the evolution of a toolkit of Ca2+ sensor, buffer and effector proteins. Among these toolkit components, integral and peripheral proteins decorate biomembranes and coordinate the movement of Ca2+ between compartments, sense these concentration changes and elicit physiological signals. These changes in compartmentalized Ca2+ levels are not mutually exclusive as signals propagate between compartments. For example, agonist induced surface receptor stimulation can lead to transient increases in cytosolic Ca2+ sourced from endoplasmic reticulum (ER) stores; the decrease in ER luminal Ca2+ can subsequently signal the opening surface channels which permit the movement of Ca2+ from the extracellular space to the cytosol. Remarkably, the minuscule compartments of mitochondria can function as significant cytosolic Ca2+ sinks by taking up Ca2+ in a coordinated manner. In non-excitable cells, inositol 1,4,5 trisphosphate receptors (IP3Rs) on the ER respond to surface receptor stimulation; stromal interaction molecules (STIMs) sense the ER luminal Ca2+ depletion and activate surface Orai1 channels; surface Orai1 channels selectively permit the movement of Ca2+ from the extracellular space to the cytosol; uptake of Ca2+ into the matrix through the mitochondrial Ca2+ uniporter (MCU) further shapes the cytosolic Ca2+ levels. Recent structural elucidations of these key Ca2+ toolkit components have improved our understanding of how they function to orchestrate precise cytosolic Ca2+ levels for specific physiological responses. This chapter reviews the atomic-resolution structures of IP3R, STIM1, Orai1 and MCU elucidated by X-ray crystallography, electron microscopy and NMR and discusses the mechanisms underlying their biological functions in their respective compartments within the cell. PMID- 29594865 TI - Assembly of ER-PM Junctions: A Critical Determinant in the Regulation of SOCE and TRPC1. AB - Store-operated calcium entry (SOCE), a unique plasma membrane Ca2+ entry mechanism, is activated when ER-[Ca2+] is decreased. SOCE is mediated via the primary channel, Orai1, as well as others such as TRPC1. STIM1 and STIM2 are ER Ca2+ sensor proteins that regulate Orai1 and TRPC1. SOCE requires assembly of STIM proteins with the plasma membrane channels which occurs within distinct regions in the cell that have been termed as endoplasmic reticulum (ER)-plasma membrane (PM) junctions. The PM and ER are in close proximity to each other within this region, which allows STIM1 in the ER to interact with and activate either Orai1 or TRPC1 in the plasma membrane. Activation and regulation of SOCE involves dynamic assembly of various components that are involved in mediating Ca2+ entry as well as those that determine the formation and stabilization of the junctions. These components include proteins in the cytosol, ER and PM, as well as lipids in the PM. Recent studies have also suggested that SOCE and its components are compartmentalized within ER-PM junctions and that this process might require remodeling of the plasma membrane lipids and reorganization of structural and scaffolding proteins. Such compartmentalization leads to the generation of spatially- and temporally-controlled Ca2+signals that are critical for regulating many downstream cellular functions. PMID- 29594866 TI - Beyond Intracellular Signaling: The Ins and Outs of Second Messengers Microdomains. AB - A typical characteristic of eukaryotic cells compared to prokaryotes is represented by the spatial heterogeneity of the different structural and functional components: for example, most of the genetic material is surrounded by a highly specific membrane structure (the nuclear membrane), continuous with, yet largely different from, the endoplasmic reticulum (ER); oxidative phosphorylation is carried out by organelles enclosed by a double membrane, the mitochondria; in addition, distinct domains, enriched in specific proteins, are present in the plasma membrane (PM) of most cells. Less obvious, but now generally accepted, is the notion that even the concentration of small molecules such as second messengers (Ca2+ and cAMP in particular) can be highly heterogeneous within cells. In the case of most organelles, the differences in the luminal levels of second messengers depend either on the existence on their membrane of proteins that allow the accumulation/release of the second messenger (e.g., in the case of Ca2+, pumps, exchangers or channels), or on the synthesis and degradation of the specific molecule within the lumen (the autonomous intramitochondrial cAMP system). It needs stressing that the existence of a surrounding membrane does not necessarily imply the existence of a gradient between the cytosol and the organelle lumen. For example, the nuclear membrane is highly permeable to both Ca2+ and cAMP (nuclear pores are permeable to solutes up to 50 kDa) and differences in [Ca2+] or [cAMP] between cytoplasm and nucleoplasm are not seen in steady state and only very transiently during cell activation. A similar situation has been observed, as far as Ca2+ is concerned, in peroxisomes. PMID- 29594867 TI - Mitochondrial VDAC, the Na+/Ca2+ Exchanger, and the Ca2+ Uniporter in Ca2+ Dynamics and Signaling. AB - Mitochondrial Ca2+ uptake and release play pivotal roles in cellular physiology by regulating intracellular Ca2+ signaling, energy metabolism, and cell death. Ca2+ transport across the inner and outer mitochondrial membranes (IMM, OMM, respectively), is mediated by several proteins, including the voltage-dependent anion channel 1 (VDAC1) in the OMM, and the mitochondrial Ca2+ uniporter (MCU) and Na+-dependent mitochondrial Ca2+ efflux transporter, (the NCLX), both in the IMM. By transporting Ca2+ across the OMM to the mitochondrial inner-membrane space (IMS), VDAC1 allows Ca2+ access to the MCU, facilitating transport of Ca2+ to the matrix, and also from the IMS to the cytosol. Intra-mitochondrial Ca2+ controls energy production and metabolism by modulating critical enzymes in the tricarboxylic acid (TCA) cycle and fatty acid oxidation. Thus, by transporting Ca2+, VDAC1 plays a fundamental role in regulating mitochondrial Ca2+ homeostasis, oxidative phosphorylation, and Ca2+ crosstalk among mitochondria, cytoplasm, and the endoplasmic reticulum (ER). VDAC1 has also been recognized as a key protein in mitochondria-mediated apoptosis, and apoptosis stimuli induce overexpression of the protein in a Ca2+-dependent manner. The overexpressed VDAC1 undergoes oligomerization leading to the formation of a channel, through which apoptogenic agents can be released. Here, we review the roles of VDAC1 in mitochondrial Ca2+ homeostasis, in apoptosis, and in diseases associated with mitochondria dysfunction. PMID- 29594868 TI - Annexins: Ca2+ Effectors Determining Membrane Trafficking in the Late Endocytic Compartment. AB - Despite the discovery of annexins 40 years ago, we are just beginning to understand some of the functions of these still enigmatic proteins. Defined and characterized by their ability to bind anionic membrane lipids in a Ca2+ dependent manner, each annexin has to be considered a multifunctional protein, with a multitude of cellular locations and diverse activities. Underlying causes for this considerable functional diversity include their capability to associate with multiple cytosolic and membrane proteins. In recent years, the increasingly recognized establishment of membrane contact sites between subcellular compartments opens a new scenario for annexins as instrumental players to link Ca2+ signalling with the integration of membrane trafficking in many facets of cell physiology. In this chapter, we review and discuss current knowledge on the contribution of annexins in the biogenesis and functioning of the late endocytic compartment, affecting endo- and exocytic pathways in a variety of physiological consequences ranging from membrane repair, lysosomal exocytosis, to cell migration. PMID- 29594869 TI - Ca2+ Signalling and Membrane Dynamics During Cytokinesis in Animal Cells. AB - Interest in the role of Ca2+ signalling as a possible regulator of the combinatorial processes that result in the separation of the daughter cells during cytokinesis, extend back almost a 100 years. One of the key processes required for the successful completion of cytokinesis in animal cells (especially in the large holoblastically and meroblastically dividing embryonic cells of a number of amphibian and fish species), is the dynamic remodelling of the plasma membrane. Ca2+ signalling was subsequently demonstrated to regulate various different aspects of cytokinesis in animal cells, and so here we focus specifically on the role of Ca2+ signalling in the remodelling of the plasma membrane. We begin by providing a brief history of the animal models used and the research accomplished by the early twentieth century investigators, with regards to this aspect of animal cell cytokinesis. We then review the most recent progress made (i.e., in the last 10 years), which has significantly advanced our current understanding on the role of cytokinetic Ca2+ signalling in membrane remodelling. To this end, we initially summarize what is currently known about the Ca2+ transients generated during animal cell cytokinesis, and then we describe the latest findings regarding the source of Ca2+ generating these transients. Finally, we review the current evidence about the possible targets of the different cytokinetic Ca2+ transients with a particular emphasis on those that either directly or indirectly affect plasma membrane dynamics. With regards to the latter, we discuss the possible role of the early Ca2+ signalling events in the deformation of the plasma membrane at the start of cytokinesis (i.e., during furrow positioning), as well as the role of the subsequent Ca2+ signals in the trafficking and fusion of vesicles, which help to remodel the plasma membrane during the final stages of cell division. As it is becoming clear that each of the cytokinetic Ca2+ transients might have multiple, integrated targets, deciphering the precise role of each transient represents a significant (and ongoing) challenge. PMID- 29594871 TI - Solid-phase microextraction of sulfonylurea herbicides by using borate-reinforced multiple monolithic fibers. AB - Boron-nitrogen coordination is a useful interaction for use in the extraction of amino-nitrogen-containing compounds. A new monolithic adsorbent is described here that consisted of poly(acrylamidophenyl boronic acid/vinyl-3-octylimidazolium tetrafluroborate-co-divinylbenzene/ethylene dimethacrylate) polymer. It was synthesized with the aim to obtain a new kind of extraction phase for multiple monolith based fiber solid-phase microextraction of sulfonylurea herbicides. Results indicate that boron-nitrogen coordination interaction plays a key role in the efficient extraction. It is also found that soaking the sorbent in a borate solution further improves the enrichment performance. The preparation conditions and extraction parameters were optimized. Following extraction with the adsorbent, the sulfonylurea herbicides were submitted to quantitation by HPLC with DAD detection. The limits of detection are in the range of 9.0-18 ng.L-1. The method was applied to monitor the herbicides in samples of tap, river and waste waters. Recoveries at spiking levels of 1.0, 10 and 100 MUg.L-1 are in the range of 70.1-108%, and the values for relative standard deviation are less than 10% for all analytes in all cases.

PMID- 29594870 TI - Treatment Strategies for Dravet Syndrome. AB - Dravet syndrome (DS) is a medically refractory epilepsy that onsets in the first year of life with prolonged seizures, often triggered by fever. Over time, patients develop other seizure types (myoclonic, atypical absences, drops), intellectual disability, crouch gait and other co-morbidities (sleep problems, autonomic dysfunction). Complete seizure control is generally not achievable with current therapies, and the goals of treatment are to balance reduction of seizure burden with adverse effects of therapies. Treatment of co-morbidities must also be addressed, as they have a significant impact on the quality of life of patients with DS. Seizures are typically worsened with sodium-channel agents. Accepted first-line agents include clobazam and valproic acid, although these rarely provide adequate seizure control. Benefit has also been noted with topiramate, levetiracetam, the ketogenic diet and vagal nerve stimulation. Several agents presently in development, specifically fenfluramine and cannabidiol, have shown efficacy in clinical trials. Status epilepticus is a recurring problem for patients with DS, particularly in their early childhood years. All patients should be prescribed a home rescue therapy (usually a benzodiazepine) but should also have a written seizure action plan that outlines when rescue should be given and further steps to take in the local hospital if the seizure persists despite home rescue therapy. PMID- 29594873 TI - Reliability and validity of the Short Falls Efficacy Scale-International for Japanese older people. AB - BACKGROUND: The Short Falls Efficacy Scale-International (Short FES-I) has been confirmed to be a good measure with reliability and validity in a UK sample; however, the reliability and validity of the Short FES-I for Japanese older people have not yet been established. AIM: The aim of this study was to determine the reliability and validity of the Short FES-I for Japanese older people. METHODS: The study participants were 519 older people aged 65 years and over who were living independently in their community. The Short FES-I is composed of seven items rated on a four-point Likert scale. Lower scores indicate better fall related efficacy. To investigate the validity of the Short FES-I, previous falls, physical function such as grip strength and scores on the Timed Up and Go (TUG) test, psychological factors such as self-rated health (SRH), cognitive function, and other confounding factors were collected. The association between the previous falls and the Short FES-I was analyzed using logistic regression analysis. Furthermore, factors related to the Short FES-I were investigated using multiple regression analysis. RESULTS: Cronbach's alpha for the Short FES-I was 0.87. Short FES-I scores were significantly higher in participants with a history of falls than in those without. In addition, Short FES-I scores were significantly and independently associated with falls in logistic regression analysis, and significantly associated with grip strength, TUG time, and SRH in multiple regression analysis. CONCLUSIONS AND DISCUSSION: These results suggest that the Short FES-I is a reliable and valid fall-related measurement scale for Japanese older people.

AB - Evidence suggests a predictive link between elevated basal activity within reward related networks (e.g., cortico-basal ganglia-thalamic networks) and vulnerability for alcoholism. Both calcium channel function and cyclic adenosine monophosphate (cAMP)/protein kinase A-mediated signaling are critical modulators of reward neurocircuitry and reward-related behaviors. Calcium/calmodulin stimulated adenylyl cyclases (AC) 1 and 8 are sensitive to activity-dependent increases in intracellular calcium and catalyze cAMP production. Therefore, we hypothesized AC1 and 8 regulate brain activity in reward regions of the cortico basal ganglia-thalamic circuit and that this regulatory influence predicts voluntary ethanol drinking responses. This hypothesis was evaluated by manganese enhanced magnetic resonance imaging and chronic, intermittent ethanol access procedures. Ethanol-naive mice with genetic deletion of both AC1 and 8 (DKO mice) exhibited bilateral reductions in baseline activity within cortico-basal ganglia thalamic regions associated with reward processing compared to wild-type controls (WT, C57BL/6 mice). Significant activity changes were not evident in regions either outside of the cortico-basal ganglia-thalamic network or within the network that are not associated with reward processing. Parallel studies demonstrated that reward network hypoactivity in DKO mice predicted a significant attenuation in consumption and preference levels to escalating ethanol concentrations (12, 20 and 30%) compared to WT mice, an effect that was maintained over extended access (14 sessions) to 20% ethanol. Summarizing, these data support a contribution of AC1 and 8 in cortico-basal ganglia-thalamic activity and the predictive value of this regulatory influence on ethanol drinking behavior, which merits the future evaluation of calcium-stimulated ACs in the neural processes that engender vulnerability to maladaptive alcohol drinking. PMID- 29594874 TI - Oligometastatic cancer in elderly patients: the "blitzkrieg" radiotherapy approach AB - AIMS: To retrospectively evaluate the outcome of stereotactic body radiation therapy (SBRT) in the treatment of elderly patients affected by isolated body metastasis from different primitive tumors. METHODS: 70 patients with isolated body metastasis were treated. Median age at diagnosis was 75 years (IQR 69-80). The most common SBRT fractionation scheme was 5 * 7 Gy (total dose 35 Gy). The primary endpoints were Local Control (LC) and Toxicity. Secondary endpoints were Overall Survival (OS) and Disease-Specific Survival (DSS). Response to radiotherapy was assessed according to RECIST criteria v1.1. Toxicity was registered according to Common Terminology Criteria for Adverse Events (CTCAE) v 4.0. We performed survival analysis with the Kaplan-Meier method. The correlation between time actuarial incidence and clinical parameters was studied. RESULTS: Median follow-up was 26.5 months. 44 patients (62.8%) were alive at the time of analysis, while 22 (31.4%) died because of the disease. Local control at 2 and 3 years was 87%. The 2-year OS and DSS were 84 and 71%, respectively, while the 3 year values were 57 and 62%. PFS at 2 and 3 years was 41 and 25%, respectively. On univariate analysis, KPS >= 90 is statistically correlated with improved OS and DSS (p < 0.05). Acute toxicity of grade >= 2 occurred in 4 (5.7%) patients, while late toxicity >= 2 was recorded in 6 (8.6%) patients. CONCLUSIONS: Ablative Radiotherapy represents a safe, effective, and minimally invasive treatment modality for elderly oligometastatic patients who are judged unfit for systemic therapy.

AB - Carcinomas rarely occur in the heart, and cardiac surgeons are generally not familiar with cardiac tumors. Some characteristics of cardiac and intrapericardial tumors are reviewed to understand the features of cardiac tumors. Cardiac tumors are discussed separately from intrapericardial tumors. Primary cardiac tumors are predominantly benign whereas primary intrapericardial tumors are usually malignant. The prevalence of each tumor types is presented in this review. In both cardiac and intrapericardial tumors, the incidences of metastatic tumors from cancers outside of the heart are high with carcinomas occupying more than half of the cases. Generally, the prognosis of primary malignant cardiac tumors is very poor. Cardiac tumors metastasize to other organs as hematogenous metastases. Surgery must be performed based on all the above mentioned features of both cardiac and intrapericardial tumors. PMID- 29594876 TI - Is the frozen elephant trunk frozen? AB - The elephant trunks, either conventional or frozen represent the major technical improvements in the treatment of complex thoracic aortic disease. In the last decades, these useful techniques progressively evolved along with the introduction of new devices to facilitate the procedure and ameliorate post operative results. The latest multi-branched hybrid FET prostheses give us the opportunity to greatly facilitate graft implantation and reduce operative times. The following review will provide an overview of the FET technique throughout the current available devices, possible surgical indications and principal surgical steps. PMID- 29594877 TI - Granulocyte colony stimulating factor-producing lung cancer with severe anemia of inflammation. AB - Granulocyte colony stimulating factor (G-CSF)-producing lung cancer occasionally induces severe inflammation with an abnormally high white blood cell count. Herein, we report a 49-year-old man who suffered from resectable G-CSF-producing non-small cell lung cancer with continuous fever and severe anemia. Red blood cell transfusion was necessary for the anemia of inflammation. The patient underwent complete surgical tumor resection. The histopathological diagnosis was a pleomorphic carcinoma at pathological stage IIB. This is apparently the first successful case of surgical resection of G-CSF-producing lung cancer in a patient with severe anemia and uncontrollable fever. PMID- 29594878 TI - Acquired resistance to an epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in an uncommon G719S EGFR mutation. AB - Background Acquired resistance (AR) to an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a common event, and several underlying mechanisms, including T790 M, MET amplification and PTEN downregulation, have been reported for the common EGFR mutations. EGFR G719X is an uncommon mutation that has been reported to show sensitivity to EGFR-TKIs. However, no established cell lines harboring the EGFR G719X have been reported in the literature. Materials and Methods G719S-GR cells were established from malignant pleural effusion of a patient whose tumor developed AR from gefitinib treatment. G719S-GR cells were then genotyped and tested for drug sensitivities. Multiplex ligation dependent probe amplification (MLPA) was used to compare the clinical tumor samples with G719S-GR. Results G719S-GR cells were resistant to EGFR-TKIs with an LC50 of around 10 MUM. A genomic analysis showed that G719S-GR cells harbor the EGFR G719S mutation as well as the amplification of EGFR locus. The homozygous deletion of CDKN2A and the loss of PTEN and TSC1 were also detected. On comparing the copy number of tumor suppressor genes using MLPA, G719S-GR cells were found to lack one copy of PTEN, which was not observed in a tumor obtained before gefitinib treatment. Loss of PTEN may result in AKT activation. The mTORC1/2 inhibitor Torin-1 was able to inhibit the downstream signaling when combined with osimertinib. Discussion The newly established G719S-GR cell line may be useful for investigating the mechanism underlying the development of AR in the G719X mutation; the loss of PTEN may be one such mechanism. PMID- 29594879 TI - Matrix-MTM adjuvant enhances immunogenicity of both protein- and modified vaccinia virus Ankara-based influenza vaccines in mice. AB - Influenza viruses continuously circulate in the human population and escape recognition by virus neutralizing antibodies induced by prior infection or vaccination through accumulation of mutations in the surface proteins hemagglutinin (HA) and neuraminidase (NA). Various strategies to develop a vaccine that provides broad protection against different influenza A viruses are under investigation, including use of recombinant (r) viral vectors and adjuvants. The replication-deficient modified vaccinia virus Ankara (MVA) is a promising vaccine vector that efficiently induces B and T cell responses specific for the antigen of interest. It is assumed that live vaccine vectors do not require an adjuvant to be immunogenic as the vector already mediates recruitment and activation of immune cells. To address this topic, BALB/c mice were vaccinated with either protein- or rMVA-based HA influenza vaccines, formulated with or without the saponin-based Matrix-MTM adjuvant. Co-formulation with Matrix M significantly increased HA vaccine immunogenicity, resulting in antigen specific humoral and cellular immune responses comparable to those induced by unadjuvanted rMVA-HA. Of special interest, rMVA-HA immunogenicity was also enhanced by addition of Matrix-M, demonstrated by enhanced HA inhibition antibody titres and cellular immune responses. Matrix-M added to either protein- or rMVA based HA vaccines mediated recruitment and activation of antigen-presenting cells and lymphocytes to the draining lymph node 24 and 48 h post-vaccination. Taken together, these results suggest that adjuvants can be used not only with protein based vaccines but also in combination with rMVA to increase vaccine immunogenicity, which may be a step forward to generate new and more effective influenza vaccines.

AB - Hydrothermal carbonization (HTC) is a thermochemical process carried out in an aqueous medium. It is capable of converting biomass into a solid, carbon-rich material (hydrochar), and producing a liquid phase (process water) which contains the unreactive feedstock and/or chemical intermediates from the carbonization reaction. The aim of this study was to evaluate the characteristics of process water generated by HTC from vinasse and sugarcane bagasse produced by sugarcane industry and to evaluate its toxicity to both marine (using Artemia salina as a model organism) and the terrestrial environment (through seed germination studies of maize, lettuce, and tomato). The experiments showed that concentrated process water completely inhibited germination of maize, lettuce, and tomato seeds. On the other hand, diluted process water was able to stimulate seedlings of maize and tomato and enhance root and shoot growth. For Artemia, the LC50 indicated that the process water is practically non-toxic; however, morphological changes, especially damages to the digestive tube and antennas of Artemia, were observed for the concentration of 1000 mg C L-1. PMID- 29594881 TI - Potential application of pre-treated municipal solid waste incineration fly ash as cement supplement. AB - Pre-treatment process carried out on raw municipal solid waste incineration (MSWI) fly ash (FA) sample that did not comply initially with the USEPA method 1311 toxicity characteristic leaching procedure (TCLP) regulatory limits of 2011 reduced its chloride and heavy metal content appreciably, thereby making it compliant with the aforementioned regulatory requirement. More than 98% of each heavy metal was successfully removed. The process was excellent in removing cadmium (Cd) (99.99%) and very good at removing the rest. About 99.96% of Cu was eliminated, 99.96% of cobalt (Co), 99.95% of Zn, 98.61% of Cr, and 98.12% of nickel (Ni). Also, the leachate resulting from these pre-treatment steps met the China (GB 16889-2008) and USEPA method 1311 regulatory standards for safe discharge. The density and compressive strength of all the samples prepared increased as the FA content decreased. The compressive strength of all the samples passed the 1989 USEPA-recommended value of 0.34 MPa (50 psi), thereby making them suitable for industrial application. The sample that attained the highest compressive strength (2.08 MPa) after 28 days of curing incorporated 55% fly ash (FACS55), while the one with the least compressive strength (0.65 MPa) after the same period was made from only fly ash (FACS100). Moreover, the concentration of heavy metals in all the samples generally decreased with the FA content. Chromium was not detected in all the samples, thereby making this an excellent method for its immobilization. From the leachability test results, all the samples prepared met the USEPA method 1311 TCLP regulatory limits. PMID- 29594882 TI - Decomposition dynamic of two aquatic macrophytes Trapa bispinosa Roxb. and Nelumbo nucifera detritus. AB - In freshwater ecosystems, aquatic macrophytes play significant roles in nutrient cycling. One problem in this process is nutrient loss in the tissues of untimely harvested plants. In this study, we used two aquatic species, Nelumbo nucifera and Trapa bispinosa Roxb., to investigate the decomposition dynamics and nutrient release from detritus. Litter bags containing 10 g of stems (plus petioles) and leaves for each species detritus were incubated in the pond from November 2016 to May 2017. Nine times litterbags were retrieved on days 6, 14, 25, 45, 65, 90, 125, 145, and 165 after the decomposition experiment for the monitoring of biomass loss and nutrient release. The results suggested that the dry masses of N. nucifera and T. bispinosa decomposed by 49.35-69.40 and 82.65-91.65%, respectively. The order of decomposition rate constants (k) is as follows: leaves of T. bispinosa (0.0122 day-1) > stems (plus petioles) of T. bispinosa (0.0090 day-1) > leaves of N. nucifera (0.0060 day-1) > stems (plus petioles) of N. nucifera (0.0030 day-1). Additionally, the orders of time for 50% dry mass decay, time for 95% dry mass decay, and turnover rate are as follows: leaves < stems (plus petioles) and T. bispinosa < N. nucifera, respectively. This result indicated that the dry mass loss, k values, and other parameters related to k values are significantly different in species- and tissue-specific. The C, N, and P concentration and the C/N, C/P, and N/P ratios presented the irregular temporal changes trends during the whole decay period. In addition, nutrient accumulation index (AI) was significantly changed depending on the dry mass remaining and C, N, and P concentration in detritus at different decomposition times. The nutrient AIs were 36.72, 8.08, 6.35, and 2.56% for N; 31.25, 9.85, 4.00, and 1.63% for P; 25.15, 16.96, 7.36, and 6.16% for C in the stems (plus petioles) of N. nucifera, leaves of N. nucifera, stems (plus petioles) of T. bispinosa, and leaves of T. bispinosa, respectively, at the day 165. These results indicated that 63.28 97.44% of N, 68.75-98.37% of P, and 74.85-93.84% of C were released from the plant detritus to the water at the day 165 of the decomposition period. The initial detritus chemistry, particularly the P-related parameters (P concentration and C/P and N/P ratios), strongly affected dry mass loss, decomposition rates, and nutrient released from detritus into water. Two-way ANOVA results also confirm that the effects on the species were significant for decomposition dynamics (dry mass loss), nutrient release (nutrient concentration, their ratios, and nutrient AI) (P < 0.01), and expected N concentration (P > 0.05). In addition, the decomposition time had also significant effects on the detritus decomposition dynamic and nutrient release. However, the contributors of species and decomposition time on detritus decomposition were significantly different on the basis of their F values of two-way ANOVA results. This study can provide scientific bases for the aquatic plant scientific management in freshwater ecosystems of the East region of China. PMID- 29594883 TI - Effect of hydration status on pesticide uptake in anurans following exposure to contaminated soils. AB - In this study, the impact of hydration status on dermal uptake of pesticides in two species of amphibians is examined. Absorption of pesticides in anurans occurs primarily through a highly vascularized dermal seat patch; however, pesticides can also enter through the superficial dermis following exposure. Despite the growing body of literature on dermal exposure in amphibians, little is known on how hydration status influences uptake. Thus, the objective of this study was to investigate the influence of hydration status on absorption of pesticides (atrazine, triadimefon, metolachlor, chlorothalonil, and imidacloprid) in southern leopard frogs (Lithobates sphenocephala) and Fowler's toads (Anaxyrus fowleri). Amphibian treatments included dehydration periods of 0, 2, 4, 6, 8, or 10 h prior to exposure to pesticide-contaminated soils for 8 h. Following exposure, soil and whole-body homogenates were extracted and analyzed by LC MS/MS. Dehydration time was then regressed against post-exposure concentrations to infer the impact of dehydration on dermal pesticide uptake. Increased dehydration time resulted in significantly lowered pesticide concentrations in both species (F6, 293 = 67.66, p = 0.007) for the five pesticides studied. This phenomenon could be due to an energy and/or dilution effect. PMID- 29594884 TI - An eco-friendly method for heavy metal removal from mine tailings. AB - One of the serious environmental problems that society is facing today is mine tailings. These byproducts of the process of extraction of valuable elements from ores are a source of pollution and a threat to the environment. For example, mine tailings from past mining activities at Giant Mines, Yellowknife, are deposited in chambers, stopes, and tailing ponds close to the shores of The Great Slave Lake. One of the environmentally friendly approaches for removing heavy metals from these contaminated tailing is by using biosurfactants during the process of soil washing. The objective of this present study is to investigate the effect of sophorolipid (SL) concentration, the volume of washing solution per gram of medium, pH, and temperature on the efficiency of sophorolipids in removing heavy metals from mine tailings. It was found that the efficiency of the sophorolipids depends on its concentration, and is greatly affected by changes in pH, and temperature. The results of this experiment show that increasing the temperature from 15 to 23 degrees C, while using sophorolipids, resulted in an increase in the removal of iron, copper, and arsenic from the mine tailing specimen, from 0.25, 2.1, and 8.6 to 0.4, 3.3, and 11.7%. At the same time, increasing the temperature of deionized water (DIW) from 15 to 23 degrees C led to an increase in the removal of iron, copper, and arsenic from 0.03, 0.9, and 1.8 to 0.04, 1.1, and 2.1%, respectively. By increasing temperature from 23 to 35 degrees C, when using sophorolipids, 22% reduction in the removal of arsenic was observed. At the same time while using DI water as the washing solution, increasing temperature from 23 to 35 degrees C resulted in 6.2% increase in arsenic removal. The results from this present study indicate that sophorolipids are promising agents for replacing synthetic surfactants in the removal of arsenic and other heavy metals from soil and mine tailings. PMID- 29594885 TI - Effect on human health of the arsenic pollution and hydrogeochemistry of the Yazir Lake wetland (Cavdir-Burdur/Turkey). AB - In this study, the physicochemical parameters, major ions and arsenic (As) contents of water resources in the Yazir lake wetland, were evaluated. In addition, water resources in this region were investigated from the point of water quality and health risk assessment. Thirty water samples were collected from the area in dry and wet seasons. Ca-Mg-HCO3 and Ca-HCO3 were the dominant water types. The Gibbs diagram suggests that most of the samples fall in rock dominance zone, which indicates the groundwater interaction between rock chemistry. When compared to drinking water guidelines established by World Health Organization and Turkey, much greater attention should be paid to As, Fe, and Mn through varied chemicals above the critical values. According to the pH-ORP diagram, the predominant species is arsenate (H2AsO4-2). The high concentrations of As in the surface water and groundwater are related to oxidative and reductive dissolution reaction of Fe and Mn hydroxides within the Kizilcadag ophiolite and melange. In addition, the seasonal changes in As concentrations depend on the increase in pH of water samples. The major toxic and carcinogenic chemical within water samples is As for groundwater and surface water. From the results of hazard index, it is verified that As which is taken by ingestion of water was the main contaminant, and toxic human risk in the study area. The obtained results will help define strategies for As problems in the water resources in future. PMID- 29594886 TI - Explaining the accelerated degradation of ciprofloxacin, sulfamethazine, and erythromycin in different soil exposure scenarios by their aqueous extractability. AB - Antibiotics are frequently introduced into agricultural soils with the application of sewage sludge or farm organic fertilizers. Repeated exposure of soils to a pollutant can enrich for microbial populations that metabolize the chemical, reducing its environmental persistence. In London, Canada, soils from a long-term field experiment have received different concentrations of antibiotics annually for several years. The purpose of the present study was to assess the bioavailability of sulfamethazine, erythromycin, or ciprofloxacin through aqueous extractions with borax or EDTA solutions and their biodegradation following different soil exposure scenarios. Control soils and soils treated annually in the field with 10 mg antibiotics per kg were sampled, supplemented in the laboratory with radiolabeled antibiotic either added directly or carried in dairy manure. Sulfamethazine and erythromycin were initially more bioavailable than ciprofloxacin, with aqueous extractabilities representing 60, 36, and 8%, respectively. Sulfamethazine and erythromycin were degraded in soils, with a larger fraction mineralized in the long-term exposed soil (20 and 65%, respectively) than in control soil (0.4 and 3%, respectively) after 7 days of incubation. In contrast, ciprofloxacin was not mineralized neither in control nor long-term exposed soils. The mineralized fractions were similar for antibiotics added directly to soil or carried in dairy manure. PMID- 29594887 TI - Purifying arsenic and fluoride-contaminated water by a novel graphene-based nanocomposite membrane of enhanced selectivity and sustained flux. AB - A novel graphene-based nanocomposite membrane was synthesized by interfacial polymerization (IP) through chemical bonding of the graphene oxide (GO) layer to polyethersulfone surface. Detailed characterization of the composite membrane through AFM, SEM, ATR-FTIR, XRD analysis, and Raman spectroscopy indicates strong potential of the membrane in highly selective removal of the toxic contaminants like arsenic and fluoride while permeating the essential minerals like calcium and magnesium. This makes the membrane suitable for production of safe drinking water from contaminated water. The membrane applied in a flat-sheet cross-flow module succeeded in removal of more than 98% arsenic and around 80% fluoride from contaminated water while selectively retaining the useful calcium and magnesium minerals in drinking water. A sustained pure water flux of around 150 LMH (liter per square meter per hour) during operation over long hours (> 150 h) with only 3 5% drop in flux indicates antifouling character of the membrane module. PMID- 29594888 TI - An analysis of the dust deposition on solar photovoltaic modules. AB - Solid particles impair the performance of the photovoltaic (PV) modules. This results in power losses which lower the efficiency of the system as well as the increases of temperature which additionally decreases the performance and lifetime. The deposited dust chemical composition, concentration and formation of a dust layer on the PV surface differ significantly in reference to time and location. In this study, an evaluation of dust deposition on the PV front cover glass during the non-heating season in one of the most polluted European cities, Krakow, was performed. The time-dependent particle deposition and its correlation to the air pollution with particulate matter were analysed. Dust deposited on several identical PV modules during variable exposure periods (from 1 day up to 1 week) and the samples of total suspended particles (TSP) on quartz fibre filters using a low volume sampler were collected during the non-heating season in the period of 5 weeks. The concentration of TSP in the study period ranged between 12.5 and 60.05 MUg m-3 while the concentration of PM10 observed in the Voivodeship Inspectorate of Environmental Protection traffic station, located 1.2 km from the TSP sampler, ranged from 14 to 47 MUg m-3. It was revealed that dust deposition density on a PV surface ranged from 7.5 to 42.1 mg m-2 for exposure periods of 1 day while the measured weekly dust deposition densities ranged from 25.8 to 277.0 mg m-2. The precipitation volume and its intensity as well as humidity significantly influence the deposited dust. The rate of dust accumulation reaches approximately 40 mg m-2day-1 in the no-precipitation period and it was at least two times higher than fluxes calculated on the basis of PM10 and TSP concentrations which suggest that additional forces such as electrostatic forces significantly influence dust deposition. PMID- 29594889 TI - Lost in 'Culturation': medical informed consent in China (from a Western perspective). AB - Although Chinese law imposes informed consent for medical treatments, the Chinese understanding of this requirement is very different from the European one, mostly due to the influence of Confucianism. Chinese doctors and relatives are primarily interested in protecting the patient, even from the truth; thus, patients are commonly uninformed of their medical conditions, often at the family's request. The family plays an important role in health care decisions, even substituting their decisions for the patient's. Accordingly, instead of personal informed consent, what actually exists is 'family informed consent'. From a Western perspective, these features of Chinese law and Chinese culture might seem strange, contradicting our understanding of doctor-patient relationship and even the very essence of self-determination and fundamental rights. However, we cannot forget the huge influence of cultural factors in these domains, and that 'Western' informed consent is grounded on the individualistic nature of Western culture. This article will underline the differences between the Western and the Chinese perspectives, clarifying how each of them must be understood in its own cultural environment. But, while still respecting Chinese particularities, this paper advocates that China adopt patient individual informed consent because this is the only solution compatible with human dignity and human rights. PMID- 29594890 TI - Comparative evaluation of fermented and non-fermented de-oiled rice bran with or without exogenous enzymes supplementation in the diet of Labeo rohita (Hamilton, 1822). AB - A 60-day feeding trial was conducted to study the effect of exogenous enzymes (xylanase and phytase) supplementation in the non-fermented and fermented de oiled rice bran (DORB)-based diet of Labeo rohita. Four test diets (T1-DORB-based diet, T2-fermented DORB-based diet, T3-phytase and xylanase supplemented DORB based diet, and T4-phytase and xylanase supplemented fermented DORB-based diet) were formulated and fed to the respective groups. Test diets T3 and T4 were supplemented with 0.01% xylanase (16,000 U kg-1) and 0.01% phytase (500 U kg-1) enzymes. One hundred twenty juveniles of L. rohita, with an average weight 5.01 +/- 0.02 g, were stocked in 12 uniform size plastic rectangular tanks in triplicate with 10 fishes per tank following a completely randomized design (CRD). Exogenous enzyme supplementation to the T3 group significantly improved the growth performance of L. rohita (p < 0.05). Fermented DORB fed groups registered significantly lower growth irrespective of the supplementation of exogenous enzymes. The carcass composition (except CP %), enzyme activities (except amylase activity), globulin, and A/G ratio did not vary significantly (p > 0.05). Based on the results of the present study, it is concluded that exogenous enzyme supplementation significantly increases the growth of fish fed with DORB-based diet. PMID- 29594891 TI - Removal of totally implanted venous access ports for suspected infection in the intensive care unit: a multicenter observational study. AB - BACKGROUND: While no data support this practice, international guidelines recommend the removal of totally implanted venous access ports (TIVAPs) in patients with suspicion of TIVAP-related bloodstream infection admitted in the intensive care unit (ICU) for a life-threatening sepsis. METHODS: During this multicenter, retrospective and observational study, we included all patients admitted in five ICU for a life-threatening sepsis in whom a TIVAP was removed between January 2012 and December 2014. We aimed (1) at determining the proportion of confirmed TIVAP-related infections and (2) at assessing short- and long-term survival of patients with and without TIVAP-related infections. RESULTS: One hundred and fifty-one patients (58 +/- 14 years, 62% males) were included between 2012 and 2014. TIVAP-related infections were confirmed in 68 patients (45%). Demographic characteristics were similar between patients with and without TIVAP-related infections. SOFA score on admission per point increase [odd ratio (OR), 0.86 interval confidence (IC) 95% (0.8-0.9), p < 0.01] and local signs of infection [OR 4.0, IC 95% (1.1-15.6), p = 0.04] were significantly associated with TIVAP-related infection. Patients with TIVAP-related infection had lower ICU and 6-month mortality as compared to their counterparts (9 vs. 40%, respectively, p < 0.01; and 50 vs. 66%, respectively, p = 0.04). TIVAP-related infection was significantly associated with ICU survival [OR 0.2, IC 95% (0.05 0.5), p < 0.01]. CONCLUSIONS: TIVAP-related infection was confirmed in nearly one out of two cases of life-threatening sepsis in patients in whom it has been removed. TIVAP-related infection was associated with a good prognosis, as compared to patients with other causes of infection. PMID- 29594892 TI - Hormesis and paradoxical effects of pea (Pisum sativum L.) parameters upon exposure to formaldehyde in a wide range of doses. AB - Formaldehyde is a widespread pollutant of soil near roads including agricultural lands. Non-monotonic changes (hormesis and paradoxical effects) in chlorophyll (Ch) and carotenoid (Car) contents, the lipid peroxidation (LP) rate in plant leaves and growth parameters (GP) of plants can be caused by various pollutants. Hormesis is a biphasic dose-response phenomenon, characterised by low-dose stimulation and high-dose inhibition. The remaining types of non-monotonic responses are classified as paradoxical effects. While most authors who have studied formaldehyde and plants considered gaseous exposure to shoots, the effect of this pollutant in soil solution has been poorly examined. Thus, we studied the non-monotonic changes in Ch and Car contents, LP rate and GP in pea (Pisum sativum L.) upon exposure to formaldehyde in solution, at a wide range of sublethal concentrations from 0.063 * 10-2 to 0.16 g L-1. With formaldehyde exposure, LP and Ch contents had paradoxical effects (triphasic and multiphase changes, accordingly), while Car level did not change and GP exhibited a hormetic response. The date showed that pea parameters display diverse types of non monotonic responses upon exposure to the same formaldehyde concentrations. High pollutant concentrations (0.08-0.16 g L-1) increased LP and significantly decreased GP (to 2.3-2.5 times compared to the control), while the Ch content was increased. Lower concentrations (<0.08 g L-1) caused a moderate deviation in all parameters from the control (not more than 62%) for hormesis and paradoxical effects. PMID- 29594893 TI - The association between high-density lipoproteins and estimated glomerular filtration rate in patients without severe kidney disease. AB - PURPOSE: Several studies investigated the association between the estimated glomerular filtration rate (eGFR) and the concentration of high-density lipoproteins (HDL) in patients without severely damaged kidney function. As results of those studies were inconclusive and contradictory, we wanted to investigate this association in multiple cardiovascular disease (CVD) risk patients without severe kidney disease or renal failure. METHODS: We enrolled a cohort of 187 patients with intermediate and high CVD risk without severe renal disease. We grouped them based on their eGFR into: group 1 (>= 30 < 60 ml/min/1.73 m2), group 2 (>= 60 < 90 ml/min/1.73 m2) and group 3 (>= 90 ml/min/1.73 m2). We analyzed the difference between their HDL levels and assessed the association of HDL and eGFR in three regression models with the following predictors: model 1 (age and gender), model 2 (model 1 plus smoking status, hs CRP and diabetes mellitus) and model 3 (model 2 plus excessive weight and obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, family history of CVD and medications they used). RESULTS: Patients with the lowest eGFR had the lowest HDL values (P = 0.013). In multiple linear regression, HDL was an independent predictor of eGFR (beta = 0.189, P = 0.025) which was also shown in multinomial regression for all three models: model 1 [odds ratio (OR) 0.05; 95% confidence interval (CI) 0.007-0.331; P = 0.002], model 2 (OR 0.052; 95% CI 0.006 0.428; P = 0.006) and model 3 (OR 0.2; 95% CI 0.001-0.309; P = 0.005). CONCLUSIONS: Low HDL is an independent predictor of lower eGFR in intermediate and high CVD risk patients without severe kidney disease. In such patients, low HDL could be one of the early indicators of renal failure.

AB - BACKGROUND: Acute kidney injury (AKI) leads to serious renal damage, and early inhibition of inflammation is necessary for its treatment. C5a/C5aR signaling activation promotes inflammatory response in tissue injury. Anti-inflammatory activity of mesenchymal stem cells (MSCs) makes it possible to alleviate AKI by controlling the C5a/C5aR signaling activation. METHODS: Ischemia reperfusion (I/R)-induced AKI models in wild-type and C5aR KO mice were used. In addition, human bone marrow MSCs (hBM-MSCs) or C5aR antagonist were injected in this model. All animals were killed at 72 h after reperfusion. In vitro, the LPS-activated macrophage line RAW264.7 cells were co-cultured with or without hBM-MSCs in the presence of recombinant C5a or not for indicated time points. After that, C5aR expression, the inflammatory factor production, and NF-kappaB translocation in RAW264.7 cells were measured. RESULTS: hBM-MSC treatment and C5a/C5aR signaling blockade or C5aR-deficiency exhibited similar attenuated effects on I/R-induced AKI, macrophages infiltration, and the pro-inflammatory cytokines TNF-alpha and IL-1beta expression in renal tissues in mice. Moreover, hBM-MSC administration led to a significant reduction in C5a levels in serum and C5aR expression in the kidney tissues in mice after I/R. In vitro, upon co-culture with hBM-MSCs, both C5aR expression and the secretion of pro-inflammatory factors TNF-alpha, IL-6, and nitric oxide in LPS-activated macrophages were markedly reduced. Accordingly, recombinant complement C5a accelerated LPS-induced NF-kappaB translocation and pro-inflammatory factors expression in macrophages, but the addition of hBM-MSCs reversed these C5a-induced effects. CONCLUSIONS: The present study indicates that hBM-MSCs alleviate AKI via suppressing C5a/C5aR-NF-kappaB pathway activation.

AB - PURPOSE: The main aim of this study was to evaluate the association of computed tomography (CT) findings at admission and bowel resection rate in patients with mesenteric venous thrombosis (MVT). It was hypothesized that abnormal intestinal findings on CT were associated with a higher bowel resection rate. METHODS: Retrospective study of MVT patients treated between 2004 and 2017. CT images at admission and at follow-up were scrutinized according to a predefined protocol. Successful recanalization was defined as partial or complete recanalization of the portomesenteric venous thrombosis at the latest CT follow-up (n = 70). RESULTS: We studied 102 patients (median age 58 years, 61 men). Lifelong anticoagulation was initiated in 64 patients, and bowel resection rate was 17%. No referral letter indicated suspicion of MVT, whereas three indicated suspected intestinal ischemia. Previous venous thromboembolism was associated with increased bowel resection rate (p = 0.049). No patient with acute pancreatitis (n = 17) underwent bowel resection (p = 0.068). The presence of mesenteric oedema (p = 0.014), small bowel wall oedema (p < 0.001), small bowel dilatation (p = 0.005), and ascites (p = 0.021) were associated with increased bowel resection rate. Small bowel wall oedema remained as an independent risk factor associated with bowel resection (OR 15.8 [95% CI 3.2-77.2]). Successful thrombus recanalization was achieved in 66% of patients. CONCLUSION: The presence of abnormal intestinal findings secondary to MVT confers an excess risk of need of bowel resection due to infarction. Responsible physicians should therefore scrutinize the CT images at diagnosis together with the radiologist to better tailor clinical surveillance. PMID- 29594896 TI - In Defence of Moral Pluralism and Compromise in Health Care Networks. AB - The organisation of health care is rapidly changing. There is a trend to move away from individual health care institutions towards transmural integrated care and interorganizational collaboration in networks. However, within such collaboration and network there is often likely to be a pluralism of values as different health care institutions often have very different values. For this paper, we examine three different models of how we believe institutions can come to collaborate in networks, and thus reap the potential benefits of such collaboration, despite having different moral beliefs or values. A first way is the pragmatic way in which the different health care institutions avoid ethical reflection and focus on solutions. A second possible route is that of consensus where health care institutions base their collaboration on values that they all share. The third, and final, approach is that of compromise. Although moral compromise is often seen in a negative light, we argue that in many cases compromise might be necessary and ethically justified. In a final section, we will shift our focus from discussing various theoretical methods to allow collaboration to the potential content of consensus or compromise.

AB - As one of the most important contaminants, heavy metals can seriously influence human health via the food chain. In this study, the eco-toxicological effects of Cd2+, Pb2+, and Hg2+ on Moina mongolica Daday were investigated by feeding them Chlorella sp. that contained heavy metals. The relative body lengths of the M. mongolica changed rapidly, peaking at 2 days for Hg2+, 6 days for Cd2+, and 8 days for Pb2+. Moreover, grazing and clearance rates of the experimental group were apparently lower than those of the control group after immersion in heavy metals. Additionally, Cd2+ and Pd2+ in the food significantly influenced the mean lifespan of M. mongolica of the P and F1 generations. Egg production per brood was also significantly impacted by Cd2+ and Pb2+ in the food in generation P. Interestingly, Pb2+ was the only metal that significantly influenced the reproduction times of F2, while the reproductive times were significantly influenced by Cd2+ for generation P. Moreover, Cd2+, Pb2+, and Hg2+ in the food significantly influenced the fecundity of generation P. Evaluation of the population growth parameters of M. mongolica revealed that the intrinsic rate of increase, net reproduction rate, and finite rate of increase were significantly influenced by Cd2+, Pb2+, and Hg2+ in the food in generation P. Additionally, Hg2+ slightly impacted generation time for generation P. Finally, the acute toxicity toward M. mongolica was Hg2+ > Cd2+ > Pb2+. Overall, heavy metals in the food were likely to influence the growth, survival, and population growth of M. mongolica through the food chain. PMID- 29594898 TI - Estimation of physicochemical properties of 2-ethylhexyl-4-methoxycinnamate (EHMC) degradation products and their toxicological evaluation. AB - The organic UV filters, commonly used in personal protection products, are of concern because of their potential risk to aquatic ecosystems and living organisms. One of UV filters is ethylhexyl-4-methoxycinnamate (EHMC) acid. Studies have shown that, in the presence of oxidizing and chlorinating factors, EHMC forms a series of products with different properties than the substrate. In this study, the toxicities of EHMC and its transformation/degradation products formed under the influence of NaOCl/UV and H2O2/UV systems in the water medium were tested using Microtox(r) bioassay and by observation of mortality of juvenile crustaceans Daphnia magna and Artemia Salina. We have observed that oxidation and chlorination products of EHMC show significantly higher toxicity than EHMC alone. The toxicity of chemicals is related to their physicochemical characteristic such as lipophilicity and substituent groups. With the increase in lipophilicity of products, expressed as log KOW, the toxicity (EC50) increases. On the basis of physicochemical properties such as vapour pressure (VP), solubility (S), octanol-water partition coefficient (KOW), bioconcentration factor (BCF) and half-lives, the overall persistence (POV) and long-range transport potential (LRTP) of all the products and EHMC were calculated. It was shown that the most persistent and traveling on the long distances in environment are methoxyphenol chloroderivatives, then methoxybenzene chloroderivatives, EHMC chloroderivatives, methoxybenzaldehyde chloroderivatives and methoxycinnamate acid chloroderivatives. These compounds are also characterised by high toxicity. PMID- 29594899 TI - An evaluation of stabilised/solidified contaminated model soil using PC-based and MgO-based binders under semi-dynamic leaching conditions. AB - The leaching performance of stabilised/solidified contaminated model soil was studied to investigate the benefit of stabilisation/solidification treatment using novel binders over conventional binders. Different combinations of Portland cement (PC), ground granulated blast-furnace slag (GGBS), pulverised fly ash (PFA), and magnesia (MgO) were used and grouped into PC-based and MgO-based binders. A semi-dynamic leaching test was used, where the cumulative releases of Zn, Cu, Ni, Pb, Ca, and Mg were measured and the effective diffusion coefficients (De) and the leachability indices (LX) were calculated. The effects of different binders and water/cement ratios (w/c) on the migration of different metals after treatment were also discussed. The results showed that w/c ratio has a significant impact on the cumulative leachability of heavy metals. The diffusion coefficients of Pb and Zn are higher than those of Cu and Ni. In addition, mixes (w/c at 0.5:1) showed better performance in immobilising heavy metals than mixes (w/c at 1:1), especially in the case of Cu, Ni, and Pb. PMID- 29594900 TI - Study on hydrothermal deactivation of Pt/MnO x -CeO2 for NO x -assisted soot oxidation: redox property, surface nitrates, and oxygen vacancies. AB - The study mainly focuses on surface properties to investigate the deactivation factors of Pt/MnO x -CeO2 by H2 temperature-programmed reduction, CO chemical adsorption, NO x -temperature-programmed desorption (TPD), O2-TPD, NO temperature programmed oxidation, SEM, TEM, in situ diffuse reflectance infrared Fourier transform spectra, Raman, and thermogravimetric methods. The results show that there are three main factors to lead to hydrothermal deactivation of the catalyst: redox property, oxygen vacancy, and surface nitrates. The loss of oxygen vacancies decreases the generation and desorption of active oxygen and that of surface nitrates weakens the production of NO2 and surface peroxides (-O2 ). These factors greatly result in the damage of the C-NO2-O2 cooperative reaction. PMID- 29594901 TI - Effect of humic and fulvic acid transformation on cadmium availability to wheat cultivars in sewage sludge amended soil. AB - The high nutrients and organic matter (OM) content of sewage sludge make it an excellent fertilizer to enhance soil fertility and crop production. However, the presence of adsorbed and precipitated forms of heavy metals, especially cadmium (Cd), can be a major problem for such a utilization of sludge. This pot study aims at producing safe food with minimal Cd concentrations from sewage sludge amended soils. Two wheat cultivars (NARC-11 and Shafaq-06) were sown in soil amended with sewage sludge with rates 0, 15 and 30 g kg-1 soil. Application of sewage sludge resulted in enhancement of wheat grain yield while Cd concentrations in wheat grains of both cultivars remained within permissible limits (24.1 to 58.6 MUg kg-1 dry weight). Fourier transform infrared (FTIR) spectroscopic analysis revealed more spectral changes in fulvic acids than in humic acids, which showed a higher humification degree, making them chemically and biologically more stable for Cd retention. Sequential extraction data of Cd after NARC-11 harvest exhibited a significant decrease in mobile fractions (exchangeable and reducible fractions were reduced by 3.6 and 5.2%, respectively) and increase in immobile fraction (the oxidizable and residual fractions increased by 7 and 1.8%, respectively). It is concluded that sewage sludge application could be useful for the improvement of wheat production due to formation of stable humate complexes and decrease in Cd availability. PMID- 29594903 TI - A predictive analysis of CO2 emissions, environmental policy stringency, and economic growth in China. AB - This study takes environmental policy stringency and economic activity as the controlling variables and forecasts the CO2 emissions in China up to 2022. In doing so, an application of corrected grey model with convolution is used over the annual time series data between 1990 and 2012. The simulation results show that (1) between 2012 and 2022, CO2 emissions in China is expected to increase at an average rate of 17.46% annually, raising the emissions intensity from 7.04 in 2012 to 25.461 metric tons per capita by 2022; (2) stringent environmental policies reduce CO2 emissions-whereas, GDP tends to increase the emissions intensity in China; (3) stringent environmental policies are found to have a negative impact on GDP in China. Based on the empirical findings, the study also provides some policy suggestions to reduce emissions intensity in China. PMID- 29594902 TI - Concentration effects of the UV filter oxybenzone in Cyperus alternifolius: assessment of tolerance by stress-related response. AB - Phytoremediation has been proposed to reduce the load of the sunscreen oxybenzone (OBZ) in the aquatic environment. Despite the proven removal efficiency of this compound, little is known about its influence, particularly oxidative stress on plants. In this study, a short-term incubation of macrophytic Cyperus alternifolius was performed to prove the plant's ability to withstand the stress. Detached shoots were immersed in medium spiked with different concentrations of OBZ (50, 100, and 500 MUM) for 2, 4, and 7 days, respectively. Increased formation of O2- and H2O2 in Cyperus treated with OBZ was characterized by intense colorization following histochemical staining. Alterations of enzyme activities involved in the antioxidative defense system indicate an adaptive response of C. alternifolius to this xenobiotic stress. Quantification of lipid peroxidation reveals that no significant membrane damage occurred during incubation with OBZ. Overall, 50 MUM OBZ (tenfold higher than the amount frequently detected in the environment) exhibited low toxic effects. Accordingly, this pilot study provides information on the potential use of Cyperus to remove emerging sunscreen contaminants from water bodies. PMID- 29594904 TI - Mitigation of Cr(VI) toxicity using Pd-nanoparticles immobilized catalytic reactor (Pd-NICaR) fabricated via plasma and gamma radiation. AB - Catalytic reduction of Cr(VI) to less toxic Cr(III) form using metal nanoparticles is one of the novel approaches adopted to deal with Cr toxicity. In this work, we report the fabrication of a facile, reusable, and robust Pd nanoparticles-immobilized catalytic reactor (Pd-NICaR) system using green, environment-friendly gamma radiolytic, and plasma polymerization processes. A room temperature, RF-powered plasma polymerization process was employed to functionalize a polyethylene-polypropylene (PE-PP) non-woven matrix with epoxy group containing monomer 2,3-epoxypropyl methacrylate (EPMA). EPMA-functionalized PE-PP (EPMA-f-PE-PP) substrate was subsequently used as a template for in situ generation and immobilization of Pd NPs via gamma radiolytic route. The samples were characterized using FTIR, SEM, XPS, and XRF techniques. The catalytic efficacy of Pd-NICaR towards Cr(VI) reduction, in the presence of formic acid (FA) as a reductant, was investigated spectrophotometrically, and reaction parameters were optimized at reaction temperature of 50 degrees C and [FA]/[Cr(VI)] = 680 to achieve catalytic reduction efficiency of 99.7% within 10 min in batch process. The system showed excellent reusability (~ 20 cycles) and storage stability (> 30 days) without substantial loss (~ 11%) of activity. Practical applicability of the robust catalytic system towards Cr(VI) toxicity mitigation was established in continuous flow mode using a fixed-bed column reactor. PMID- 29594905 TI - Identification of the main mechanisms involved in the tolerance and bioremediation of Cr(VI) by Bacillus sp. SFC 500-1E. AB - Chromium pollution is a problem that affects different areas worldwide and, therefore, must be solved. Bioremediation is a promising alternative to treat environmental contamination, but finding bacterial strains able to tolerate and remove different contaminants is a major challenge, since most co-polluted sites contain mixtures of organic and inorganic substances. In the present work, Bacillus sp. SFC 500-1E, isolated from the bacterial consortium SFC 500-1 native to tannery sediments, showed tolerance to various concentrations of different phenolic compounds and heavy metals, such as Cr(VI). This strain was able to efficiently remove Cr(VI), even in the presence of phenol. The detection of the chrA gene suggested that Cr(VI) extrusion could be a mechanism that allowed this strain to tolerate the heavy metal. However, reduction through cytosolic NADH dependent chromate reductases may be the main mechanism involved in the remediation. The information provided in this study about the mechanisms through which Bacillus sp. SFC 500-1E removes Cr(VI) should be taken into account for the future application of this strain as a possible candidate to remediate contaminated environments. PMID- 29594906 TI - Simultaneous determination of sulfonamides and fluoroquinolones from environmental water based on magnetic double-template molecularly imprinting technique. AB - In this work, a fast and selective method based on magnetic extraction is presented for the simultaneous extraction of sulfonamides (SAs) and fluoroquinolones (FQs), followed by liquid chromatography-tandem mass spectrometry detection. In this method, magnetic surface double-template molecularly imprinted polymers (MSdt-MIPs) with superparamagnetic property and high selectivity toward both SAs and FQs were synthesized and directly applied to the simultaneous extraction of SAs and FQs from environmental water as magnetic adsorbents. The extraction and enrichment procedures could be accomplished in one single step by stirring the mixture of MSdt-MIPs and water sample, and the MSdt MIPs with adsorbed analytes were easily separated from the water sample by a magnet afterwards. The adsorption mechanism of MSdt-MIPs was investigated by employing the adsorption thermodynamic and kinetic studies, and the selectivity of the MSdt-MIPs toward target analytes was evaluated through the selectivity test. For validation of the proposed method, the matrix effect was evaluated and compared to that of the traditional SPE method. Excellent linearity (R > 0.9990) for both SAs and FQs were obtained in the concentration range of 20-2000 ng L-1, and the limits of detection are in the range of 3.0-4.7 ng L-1 for SAs while 4.1 6.1 ng L-1 for FQs. Finally, the proposed method was successfully applied to the simultaneous determination of SAs and FQs in several environmental water samples. PMID- 29594907 TI - Association between short-term exposure to ambient air pollution and daily mortality: a time-series study in Eastern China. AB - Few studies were conducted to evaluate health effects of acute exposure to PM2.5 and daily mortality in Asian countries due to lack of large-scale PM2.5 monitoring data. We conducted a time-series study to examine the associations of short-term exposure to four common air pollutants (PM2.5, PM10, NO2, and SO2) and daily mortality in Ningbo, Zhejiang, China. We used generalized addictive model (GAM) to estimate relative risks (RRs) and 95% confidence intervals (CIs) for the association of these four air pollutants with daily mortality. The study included 9365 people in the 2-year study period from 2014 to 2015. SO2 were significantly associated with risk of NAD, RD, and CD mortality with RRs of 1.034 (95% CI 1.004, 1.064), 1.067 (95% CI 1.010, 1.127), and 1.049 (95% CI 1.001, 1.098), respectively.PM2.5 and PM10 were significantly associated with risk of death from NAD mortality in warm season. Similar associations were observed for PM10 (RR = 1.056, 95% CI 1.004, 1.111) and risk of CD mortality. The study provides further evidence that short-term exposure to PM2.5, PM10, NO2, and SO2 are associated with increased risk of daily mortality. PMID- 29594908 TI - Hematological indicators in pygmy wood mouse Apodemus uralensis (Muridae, Rodentia) populations as markers of the environmental radiation exposure: East Urals radioactive trace (Russia). AB - The hematological effects of chronic radiation exposure in males of the pygmy wood mouse (Apodemus uralensis Pall., 1811) from the East Urals radioactive trace (EURT) area were assessed, taking into account population abundance and reproductive status (immature, ripening, and mature yearlings). For this purpose, we analyzed the morpho-functional characteristics of erythrocytes (red cell indices [MCV, MCH, MCHC], red cell count, activity of antioxidant enzymes [GSH Px, CAT], lipid peroxidation, glycolysis, osmotic resistance, methaemoglobin content) and blood plasma components (free hemoglobin, total lipids, total cholesterol, and glucose) in the background territory and the EURT area; these areas have a density of soil contamination with 90Sr of 12,851 and 198 kBq * m-2, respectively (four and two order of magnitude higher than the background value). The data indicate the "hyperfunctional" state of the erythrocyte, aimed at activation of the gas transport function of blood in the radioactive environment. This, as a consequence, determines the insufficiency of energy supply of the cell defense system necessary to maintain the structural integrity of the membrane. Intensification of membrane lipid peroxidation, reduction of osmotic resistance and GSH-Px activity in red cells, an increase in the degree of intravascular hemolysis, and tendency towards erythropenia indicate the processes of accelerated aging of erythrocytes and their more pronounced destruction in the circulatory bed. The level of the hematological response increased with increasing radiation burden and was more pronounced with a large population size. The interaction effect of "overpopulation" and "radioactive pollution" was observed to a lesser degree for ripening males, and was very small for sexually mature animals. Immature males from the EURT head part with internal whole-body radiation doses of 0.0045-0.35 mGy/day can be considered as the most sensitive group to the factors synergy, including radiation damage and overabundance population. PMID- 29594909 TI - An Attenuated Highly Pathogenic Chinese PRRS Viral Vaccine Confers Cross Protection to Pigs against Challenge with the Emerging PRRSV NADC30-Like Strain. AB - A novel PRRSV strain was isolated in China that was genetically similar to the NADC30 strain which is reported to have spread throughout China. The objective of the present study was to evaluate the cross-protective efficacy of the live vaccine TJM-F92 in young pigs against challenge with a NADC30-like strain, HN201605. Twenty-five PRRSV- and antibody-free pigs were randomly divided into the following five groups: Vac/ChA, Unvac/ChA, Vac/ChB, Unvac/ChB and the mock. The pigs in groups Vac/ChA and Vac/ChB were inoculated intramuscularly with 1 mL TJM-F92 (105.0 TCID50/mL). At 28 days post vaccination (0 days post challenge), groups Vac/ChA and Unvac/ChA were inoculated intranasally with 104.5 TCID50/mL PRRSV strain TJ F3 (2 mL/pig), while groups Vac/ChB and Unvac/ChB were inoculated, using the same route, with the same dose of the NADC30-like strain HN201605 F3. Protective effects of the PRRSV strain were observed in all pigs in the Vac/ChA and Vac/ChB groups. Neither high fever nor signs of clinical disease were observed through the experiment in these groups, whereas pigs in Unvac/ChA group exhibited serious clinical symptoms, pathological lesions, and weight loss. In Unvac/ChB group, pigs developed milder clinical symptoms, which demonstrated that the NADC30-like strain HN201605 had moderate pathogenicity. The results suggest that the MLV vaccine strain TJM-F92 is an effective and safe vaccine candidate for use in China.

PMID- 29594911 TI - Analyzing the Impact of Compliance with National Guidelines for Pancreatic Cancer Care Using the National Cancer Database. AB - IMPORTANCE: Management of pancreatic cancer is complex, requiring coordination of multiple providers. National Comprehensive Cancer Network guidelines, developed for standardization and quality improvement, recommend a multimodal approach. OBJECTIVE: This study analyzed national rates of compliance with National Comprehensive Cancer Network recommendations, assessed factors affecting compliance, and evaluated whether compliance with evidence-based guidelines improved overall survival. DESIGN: This is a retrospective review of adults diagnosed with pancreatic cancer entered into the National Cancer Database. Patients included had stage I and II pancreatic cancer, and complete data in the database. Patients were classified as compliant if they underwent both surgery and a second treatment modality (chemotherapy, radiation, or chemoradiation). Clinico-pathologic variables were analyzed using univariate and multivariate models to predict overall survival. SETTING: Hospital-based national study population. PARTICIPANTS: Patients with stage I or II pancreatic cancer. MAIN OUTCOMES AND MEASURES: Compliance with National Comprehensive Cancer Network recommendations, factors affecting compliance, and overall survival based on compliance. RESULTS: A total of 52,450 patients were included; 19,272 patients (37%) were compliant. Patients were found to be most compliant in the 50-59-year old range (49% complaint), with decreased compliance at the extremes of age. Male patients were more compliant than female patients (39 vs 34%, p < 0.0001). Caucasians were more compliant (39%) than African Americans (32%) or other races (32%, p < 0.0001). Patients treated at academic/research centers were more compliant than patients treated at other facilities (39% compliant, p < 0.0001). Patients with stage II disease were more compliant compared with stage I disease (43 vs 18%, p < 0.0001). Compliance was shown to improve overall survival (p < 0.0001). CONCLUSION: Adherence to National Comprehensive Cancer Network guidelines for pancreatic cancer patients improves survival. Compliance nationwide is low, especially for older patients and minorities and those treated outside academic centers. More studies will need to be performed to identify factors that hinder compliance. PMID- 29594912 TI - Long-Term Oncologic Outcomes of Minimally Invasive Proctectomy for Rectal Adenocarcinoma. AB - BACKGROUND: Long-term oncologic outcomes after minimally invasive surgery (MIS) for rectal adenocarcinoma compared to open surgery continue to be debated. We aimed to review our high-volume single-institution outcomes in MIS rectal cancer surgery. METHODS: A retrospective review of a prospectively collected database was completed of all consecutive adult patients with rectal adenocarcinoma treated from January 2005 through December 2011. Stage IV or recurrent disease was excluded. Demographics and operative and pathologic details were reviewed and reported. Primary endpoints include survival and recurrence. RESULTS: A total of 324 patients were included and median follow-up was 54 months (IQR = 37.0, 78.8). The mean age was 58.2 +/- 14.1 years. Tumors were in the upper rectum in 111 patients, mid-rectum in 113 patients, and lower rectum in 100 patients. Stage III disease was most common (49.4%). Overall conversion to open procedure rate was 13.9%. The circumferential radial margin was positive in only 1 patient (0.3%) and the mean lymph node yield was 24.7 +/- 17.2. Cancer recurred in 42 patients (13%), 10 (2.5%) patients developed local recurrence, 32 (9.8%) developed distant metastasis, and 2 (0.6%) patients had both. The 5-year overall survival for stage 0, 1, 2, and 3 disease is 96, 91, 80, and 77%, respectively (p = 0.015). CONCLUSION: In carefully selected rectal cancer patients treated with MIS, long term outcomes of survival and recurrence appear to compare favorably to previously published series.

AB - Carbon nanotubes (CNTs) possess outstanding properties that could be useful in several technological, drug delivery, and diagnostic applications. However, their unique physical and chemical properties are hindered due to their poor solubility. This article review's the different ways and means of solubility enhancement of single-wall carbon nanotubes (SWNTs). The advantages of SWNTs over the multi-walled carbon nanotubes (MWNTs) and the method of non-covalent modification for solubility enhancement has been the key interest in this review. The review also highlights a few examples of dispersant design. The review includes some interesting utility of SWNTs being wrapped with polymer especially in biological media that could mediate proper drug delivery to target cells. Further, the use of wrapped SWNTs with phospholipids, nucleic acid, and amphiphillic polymers as biosensors is of research interest. The review aims at summarizing the developments relating to wrapped SWNTs to generate further research prospects in healthcare. PMID- 29594915 TI - Role of cardiac 123I-mIBG imaging in predicting arrhythmic events in stable chronic heart failure patients with an ICD. AB - BACKGROUND: Despite therapeutic improvement, the prognosis of chronic heart failure (CHF) remains unfavorable partly due to arrhythmia and sudden cardiac death (SCD). This prospective study evaluated myocardial 123I-meta iodobenzylguanidine (123I-mIBG) scintigraphy as a predictor of arrhythmic events (AE) in CHF patients. METHODS: 170 CHF patients referred for implantable cardioverter-defibrillator (ICD) implantation for both primary and secondary prevention were enrolled. All patients underwent planar and SPECT imaging. Early and late heart-to-mediastinum (H/M) ratio, 123I-mIBG washout (WO), early and late summed SPECT scores were calculated The primary endpoint was an AE: sustained ventricular tachycardia, resuscitated cardiac arrest, appropriate ICD therapy or SCD. The secondary endpoint was appropriate ICD therapy. RESULTS: During a median follow-up of 23.3 months, 69 patients experienced an AE. Early summed score (ESS) was the only independent predictor of AE [HR 1.023 (1.003-1.043)]. Focussing on only patients with an ICD for primary prevention, ESS was the only independent predictor of AE [HR 1.028 (1.007-1.050)]. 123I-mIBG-derived parameters failed to be independent predictors of appropriate ICD therapy. However there was a "bell shaped" relation between 123I-mIBG scintigraphy-derived parameters and AE and appropriate ICD therapy, i.e., those with intermediate 123I-mIBG abnormalities tended to be at higher risk of events. CONCLUSION: Although SPECT 123I-mIBG scintigraphy was associated with AE in CHF patients with ICD implantation for primary and secondary prevention, no association was found between 123I-mIBG scintigraphy-derived parameters and appropriate ICD therapy.

The clinical, radiographic, and histologic appearance of SMH may mimic several benign and malignant entities. Presented is a novel case, with a review of the literature focused on potential histologic diagnostic pitfalls. PMID- 29594918 TI - Squamous Cell Papillomatosis in the Setting of Recurrent Respiratory Papillomatosis. AB - A 23 year old male presented to the Otolaryngology clinic with 6 months of hoarseness and poor voice projection without improvement from speech therapy or medical anti-reflux medication. Upon examination he was found to have multiple polypoid lesions emanating from bilateral false vocal folds, left true vocal fold, and the anterior commissure. Biopsy and potassium titanyl phosphate (KTP) laser ablation with bevacizumab injection provided treatment and confirmed the clinical suspicion of squamous cell papilloma. Despite 3 years of treatment, the papillomatosis proved difficult to control, requiring a procedure approximately every 3 months. In an attempt to control the course of the disease the patient received a series of three bevacizumab and three cidofovir injections. Serial biopsies showed mild atypia within the squamous cell papillomas. Two separate biopsies confirmed presence of human papillomavirus (HPV) 6/11 via in situ hybridization with appropriate controls. There is promising research that the quadrivalent HPV (types 6, 11, 16, and 18) vaccine both reduces the disease burden in patients with active disease and reduces the incidence of recurrent respiratory papillomatosis (RRP). Other studies have shown that local immunologic dysregulation may play a role in RRP pathogenesis. Therefore new treatment options, to include PDL-1 blockade, offer hope in treating this benign condition with high morbidity and rare mortality.

AB - While metal pollution and distribution in soil are well documented for many countries, the situation is more serious in developing countries because of the rapid increase in industrialization and urbanization during last decades. Although it is well documented in developed countries, data about substantial metal pollution in Indian soil, especially in eastern Ganges alluvial plain (GAP), are limited. In this study, eight different blocks of Patna district located in eastern GAP were selected to investigate the contamination, accumulation, and sources of metals in surface soil considering different land use types. Additionally, human health risk assessment was estimated to mark the potential carcinogenic and non-carcinogenic effect of metals in soil. The concentration of all metals (except Pb) in soil was below the Indian standard limit of the potential toxic element for agricultural soil. Pb was the most abundant in soil, followed by Zn and Cu, and accounted for 52, 33 and 8% of the total metal. In terms of land use types, roadside soil detected higher concentrations of all metals, followed by park/grassland soil. Principal component analysis results indicated traffic pollution and industrial emissions are the major sources of heavy metals in soil. This was further confirmed by strong inter-correlation of heavy metals (Cd, Cr, Ni, Cu and Pb). Human health risk assessment results indicated ingestion via soil as the primary pathway of heavy metal exposure to both adults and children population. The estimated hazard index was highest for Pb, suggesting significant non-carcinogenic effect to both adults and children population. The children were more prone to the non carcinogenic effect of Pb than adults. However, relatively low cancer risk value estimated for all metals suggested non-significant carcinogenic risk in the soil.

AB - We report here the complete genome sequence of a bipartite virus, herein denoted WLPRV/human/BRA/TO-34/201, from a sample collected in 2015 from a two-year-old child in Brazil presenting acute gastroenteritis. The virus has 98-99% identity (segments 2 and 1, respectively) with the Wuhan large pig roundworm virus (unclassified RNA virus) that was recently discovered in the stomachs of pigs from China. This is the first report of a Wuhan large pig roundworm virus detected in human specimens, and the second genome described worldwide. However, the generation of more sequence data and further functional studies are required to fully understand the ecology, epidemiology, and evolution of this new unclassified virus. PMID- 29594921 TI - Bortezomib maintenance therapy in transplant-ineligible myeloma patients who plateaued after bortezomib-based induction therapy: a multicenter phase II clinical trial. AB - In the era of novel therapeutic agents for multiple myeloma (MM), both the significance of achieving the plateau phase and the efficacy of subsequent maintenance therapy remain unclear. In the present study, we evaluated the efficacy and safety of bortezomib maintenance therapy (biweekly for 1 year) in transplant-ineligible MM patients who plateaued after bortezomib-based induction therapy. Of 36 evaluable patients, the overall response rate during induction therapy was 61%, with a stringent complete response in 6%, a complete response in 6%, a very good partial response in 17%, and a partial response in 33%. Twenty patients achieved the plateau phase and subsequently received bortezomib maintenance therapy. Median progression-free survival from the induction and maintenance therapies was 13.8 months (95% confidence interval, 11.4-23.7 months) and 10.7 months (95% confidence interval, 3.7-10.7 months), respectively. During maintenance therapy, there were no cases with grade >= 2 peripheral neuropathy, nor was there any improvement in the quality of the response. In conclusion, although maintenance therapy with biweekly bortezomib for up to 1 year was feasible, plateau-oriented bortezomib induction therapy followed by bortezomib maintenance therapy was not adequate in newly diagnosed transplant-ineligible MM patients. PMID- 29594922 TI - Intensification of induction therapy and prolongation of maintenance therapy did not improve the outcome of pediatric Langerhans cell histiocytosis with single system multifocal bone lesions: results of the Japan Langerhans Cell Histiocytosis Study Group-02 Protocol Study. AB - Langerhans cell histiocytosis (LCH) with single-system (SS) multifocal bone (MFB) lesions is rarely fatal, but patients may experience relapses and develop LCH associated sequelae. To evaluate effect on outcomes of pediatric multifocal LCH, we tested a treatment protocol modified from the Japan Langerhans Cell Histiocytosis Study Group (JLSG)-96 study. We assessed the outcomes of all consecutive newly diagnosed pediatric patients with LCH with SS-MFB lesions who were treated with JLSG-02 protocol in 2002-2009. JLSG-02 was modified from JLSG 96 as follows: increased prednisolone dosage at the induction phase and extension of maintenance therapy duration from 24 to 48 weeks. In total, 82 patients with a median follow-up duration of 8.0 years were eligible for analysis. At 6 weeks, 92.7% responded to induction; however, 27.6% of responders experienced relapses. In total, 4.8% developed central nervous system-related sequelae, including central diabetes insipidus and neurodegeneration, which were associated with relapse. None of the patients died. The 5-year event-free survival rates were not different between JLSG-02 and -96 cohort (66.7 vs. 65.1%; p = 0.697). Modification of previous treatment protocol did not contribute to improvement of outcomes in LCH with SS-MFB lesions. PMID- 29594923 TI - Perioperative safety and hemostatic efficacy of Advate(r) in patients with hemophilia A in a postmarketing surveillance in Japan. AB - Rurioctocog alfa (recombinant factor VIII: Advate(r)) is available for the control of bleeding among patients with hemophilia A in Japan. To evaluate the perioperative safety and hemostatic efficacy of Advate(r), a postmarketing surveillance was conducted in Japanese patients undergoing surgery in a real world setting. A total of 74 surgical procedures performed in 58 subjects aged 0 75 years, including three females, were studied. A hemostatic efficacy rating of "excellent" or "good" was reported in 73/74 surgical procedures (98.6%). Perioperative bleeding was successfully controlled by Advate(r) in five subjects with positive FVIII inhibitors (2.4-9.1 BU/mL). Advate(r) was administered at higher initial bolus doses (114-385 IU/kg) and at higher rates by subsequent initial continuous infusion (8.3-15 IU/kg/hour) in the five subjects with inhibitor than in the subjects without inhibitor (n = 47; mean initial bolus dose: 53.4 IU/kg; subsequent mean initial continuous infusion: 3.8 IU/kg/h). Adverse drug reactions were reported in 7/74 (9.5%) procedures, two of which were the development of de novo FVIII inhibitors. Overall, the perioperative use of Advate(r) in a real-world setting was found to be safe and effective among Japanese patients with hemophilia A. PMID- 29594924 TI - Hydrodynamic interaction of a self-propelling particle with a wall : Comparison between an active Janus particle and a squirmer model. AB - Using lattice Boltzmann simulations we study the hydrodynamics of an active spherical particle near a no-slip wall. We develop a computational model for an active Janus particle, by considering different and independent mobilities on the two hemispheres and compare the behaviour to a standard squirmer model. We show that the topology of the far-field hydrodynamic nature of the active Janus particle is similar to the standard squirmer model, but in the near-field the hydrodynamics differ. In order to study how the near-field effects affect the interaction between the particle and a flat wall, we compare the behaviour of a Janus swimmer and a squirmer near a no-slip surface via extensive numerical simulations. Our results show generally a good agreement between these two models, but they reveal some key differences especially with low magnitudes of the squirming parameter [Formula: see text]. Notably the affinity of the particles to be trapped at a surface is increased for the active Janus particles when compared to standard squirmers. Finally, we find that when the particle is trapped on the surface, the velocity parallel to the surface exceeds the bulk swimming speed and scales linearly with [Formula: see text]. PMID- 29594926 TI - There Are Indeed More Left-Handers Within the Autism Spectrum Disorder Compared with in the General Population, but the Many Mixed-Handers Is the More Interesting Finding. AB - Letter to the editor in response to Howard Kushner's claims that our data on non right-handedness within the autism spectrum disorder were organized, by sleight of hand, so they would give a significant result that would support our desired conclusion. Here, we have re-categorized our data, and present evidence that there are indeed more left-handers within the ASD. Furthermore, we refute claims that we have misinterpreted our results in order to conclude about a causal link between left-handedness and ASD, and highlight our original suggestion that mixed handedness, more specifically unclear handedness, is the bigger problem, and that our findings of a total 60% non-right-handedness was the more interesting finding. PMID- 29594925 TI - Deviations from Typical Developmental Trajectories Detectable at 9 Months of Age in Low Risk Children Later Diagnosed with Autism Spectrum Disorder. AB - This study was designed to track the developmental trajectory, during the first 24 months of life, of 335 low-risk infants later diagnosed with Autism Spectrum Disorder and identify early deviations observed in routine Well Care checkups. We compared their achievements to typically developing children and to children later diagnosed with non-autistic developmental impairments. The results show that in the first 6 months, the children with autism showed normal acquisition of milestones, whereas by 9 months of age they began to fail the language/communication, as well as motor items when compared to typical and delayed non-autistic children. Regular check-up visits may be useful in detecting early failure in achieving milestones, leading to earlier referral for further evaluation and treatment. PMID- 29594927 TI - Differences between immunodeficient mice generated by classical gene targeting and CRISPR/Cas9-mediated gene knockout. AB - Immunodeficient mice are widely used for pre-clinical studies to understand various human diseases. Here, we report the generation of four immunodeficient mouse models using CRISPR/Cas9 system without inserting any foreign gene sequences such as NeoR cassettes and their characterization. By eliminating any possible effects of adding a NeoR cassette, our mouse models may allow us to better elucidate the in vivo functions of each gene. Our FVB-Rag2-/-, B6-Rag2-/-, and BALB/c-Prkdc-/- mice showed phenotypes similar to those of the earlier immunodeficient mouse models, including a lack of mature B cells and T cells and an increase in the number of CD45+DX-5+ natural killer cells. However, B6-Il2rg-/ mice had a unique phenotype, with a lack of mature B cells, increased number of T cells, and decreased number of natural killer cells. Additionally, serum immunoglobulin levels in all four immunodeficient mouse models were significantly reduced when compared to those in wild-type mice with the exception of IgM in B6 Il2rg-/- mice. These results indicate that our immunodeficient mouse models are a robust tool for in vivo studies of the immune system and will provide new insights into the variation in phenotypic outcomes resulting from different gene targeting methodologies. PMID- 29594928 TI - 1H, 13C and 15N resonance assignments for a chemokine receptor-binding domain of FROUNT, a cytoplasmic regulator of chemotaxis. AB - FROUNT is a cytoplasmic protein that interacts with the membrane-proximal C terminal regions (Pro-Cs) of the CCR2 and CCR5 chemokine receptors. The interactions between FROUNT and the chemokine receptors play an important role in the migration of inflammatory immune cells. Therefore, FROUNT is a potential drug target for inflammatory diseases. However, the structural basis of the interactions between FROUNT and the chemokine receptors remains to be elucidated. We previously identified the C-terminal region (residues 532-656) of FROUNT as the structural domain responsible for the Pro-C binding, referred to as the chemokine receptor-binding domain (CRBD), and then constructed its mutant, bearing L538E/P612S mutations, with improved NMR spectral quality, referred to as CRBD_LEPS. We now report the main-chain and side-chain 1H, 13C, and 15N resonance assignments of CRBD_LEPS. The NMR signals of CRBD_LEPS were well dispersed and their intensities were uniform on the 1H-15N HSQC spectrum, and thus almost all of the main-chain and side-chain resonances were assigned. This assignment information provides the foundation for NMR studies of the three-dimensional structure of CRBD_LEPS in solution and its interactions with chemokine receptors. PMID- 29594929 TI - 1H, 13C and 15N backbone NMR chemical shift assignments of the C-terminal P4 domain of Ahnak. AB - Ahnak is a ~ 700 kDa polypeptide that was originally identified as a tumour related nuclear phosphoprotein, but later recognized to play a variety of diverse physiological roles related to cell architecture and migration. A critical function of Ahnak is modulation of Ca2+ signaling in cardiomyocytes by interacting with the beta subunit of the L-type Ca2+ channel (CaV1.2). Previous studies have identified the C-terminal region of Ahnak, designated as P3 and P4 domains, as a key mediator of its functional activity. We report here the nearly complete 1H, 13C and 15N backbone NMR chemical shift assignments of the 11 kDa C terminal P4 domain of Ahnak. This study lays the foundations for future investigations of functional dynamics, structure determination and interaction site mapping of the CaV1.2-Ahnak complex. PMID- 29594930 TI - Stability of the electroosmotic flow of a two-layer electrolyte-dielectric system with external pressure gradient?. AB - The stability of the electroosmotic flow of electrolyte-dielectric viscous liquids under the influence of the DC and AC electric fields along with the external pressure gradient is studied theoretically. Liquids are bounded by two infinite parallel plates. The lower wall bordering the electrolyte is assumed to be a charged surface, and the upper wall is electrically isolated. The charge at the lower boundary is assumed to be immobile, while the surface charge at the free surface is assumed to be mobile. In this paper, we study the micro- and nanosized liquid layers. The mathematical model is described by a nonlinear system of the Nernst-Planck-Poisson-Stokes partial differential equations with the appropriate boundary conditions on the solid surface, the electrolyte/dielectric interface, and on the upper wall. The pressure gradient is highly important for the stability of the flow. For the DC case, the external pressure could either stabilize and destabilize the flow depending on the relative directions of the electroosmotic flow and the pressure-driven flow. For the AC case, the dependence on the value of the external pressure is not monotonous for different wave numbers of perturbations, but, as a rule, the external pressure destabilizes the flow. As the frequency of the electric field increases, the one-dimensional solution of the problem becomes stable. PMID- 29594931 TI - Validation of [18F]FLT as a perfusion-independent imaging biomarker of tumour response in EGFR-mutated NSCLC patients undergoing treatment with an EGFR tyrosine kinase inhibitor. AB - BACKGROUND: 3'-Deoxy-3'-[18F]fluorothymidine ([18F]FLT) was proposed as an imaging biomarker for the assessment of in vivo cellular proliferation with positron emission tomography (PET). The current study aimed to validate [18F]FLT as a perfusion-independent PET tracer, by gaining insight in the intra-tumoural relationship between [18F]FLT uptake and perfusion in non-small cell lung cancer (NSCLC) patients undergoing treatment with a tyrosine kinase inhibitor (TKI). Six patients with metastatic NSCLC, having an activating epidermal growth factor receptor (EGFR) mutation, were included in this study. Patients underwent [15O]H2O and [18F]FLT PET/CT scans at three time points: before treatment and 7 and 28 days after treatment with a TKI (erlotinib or gefitinib). Parametric analyses were performed to generate quantitative 3D images of both perfusion measured with [15O]H2O and proliferation measured with [18F]FLT volume of distribution (V T ). A multiparametric classification was performed by classifying voxels as low and high perfusion and/or low and high [18F]FLT V T using a single global threshold for all scans and subjects. By combining these initial classifications, voxels were allocated to four categories (low perfusion low V T , low perfusion-high V T , high perfusion-low V T and high perfusion-high V T ). RESULTS: A total of 17 perfusion and 18 [18F]FLT PET/CT scans were evaluated. The average tumour values across all lesions were 0.53 +/- 0.26 mL cm- 3 min- 1 and 4.25 +/- 1.71 mL cm- 3 for perfusion and [18F]FLT V T , respectively. Multiparametric analysis suggested a shift in voxel distribution, particularly regarding the V T : from an average of >= 77% voxels classified in the "high V T category" to >= 85% voxels classified in the "low V T category". The shift was most prominent 7 days after treatment and remained relatively similar afterwards. Changes in perfusion and its spatial distribution were minimal. CONCLUSION: The present study suggests that [18F]FLT might be a perfusion-independent PET tracer for measuring tumour response as parametric changes in [18F]FLT uptake occurred independent from changes in perfusion.

AB - Infertility affects 15-20% of the reproductive age range population; the male factor accounts for up to 40-60% of these. With female factor infertility catching most of the limelight in research, diagnosis and treatment, the other half of the problem has not been duly addressed. Imaging has an important role to play in the evaluation of male infertility, especially to identify correctible (obstructive) causes. We review the scrotal, trans-rectal sonographic and Doppler findings in infertile men to aid in the accurate diagnosis and proper management of such patients. PMID- 29594933 TI - HPV Self-Sampling for Cervical Cancer Screening Among Ethnic Minority Women in South Florida: a Randomized Trial. AB - BACKGROUND: Ethnic minority women are at increased risk of cervical cancer. Self sampling for high-risk human papillomavirus (HPV) is a promising approach to increase cervical screening among hard-to-reach populations. OBJECTIVE: To compare a community health worker (CHW)-led HPV self-sampling intervention with standard cervical cancer screening approaches. DESIGN: A 26-week single-blind randomized pragmatic clinical trial. PARTICIPANTS: From October 6, 2011 to July 7, 2014, a total of 601 Black, Haitian, and Hispanic women aged 30-65 years in need of cervical cancer screening were recruited, 479 of whom completed study follow-up. INTERVENTIONS: Participants were randomized into three groups: (1) outreach by CHWs and provision of culturally tailored cervical cancer screening information (outreach), (2) individualized CHW-led education and navigation to local health care facilities for Pap smear (navigation), or (3) individualized CHW-led education with a choice of HPV self-sampling or CHW-facilitated navigation to Pap smear (self-swab option). MAIN MEASURES: The proportion of women in each group whom self-reported completion of cervical cancer screening. Women lost to follow-up were considered as not having been screened. KEY RESULTS: Of the 601 women enrolled, 355 (59%) were Hispanic, 210 (35%) were Haitian, and 36 (6%) were non-Haitian Black. In intent-to-treat analyses, 160 of 207 (77%) of women in the self-swab option group completed cervical cancer screening versus 57 of 182 (31%) in the outreach group (aOR 95% CI, p < 0.01) and 90 of 212 (43%) in the navigation group (aOR CI, p = 0.02). CONCLUSIONS: As compared to more traditional approaches, CHW-facilitated HPV self-sampling led to increased cervical cancer screening among ethnic minority women in South Florida.

AB - BACKGROUND: The transition to later-life caregiving roles, especially for couples caring for each other, can be rife with ambiguity. The incident discordance in spousal perceptions of one another's role and its relationship to mental health outcomes have not been well-described. OBJECTIVES: (1) To describe the range of daily agreement between older adult spouses' perceptions of care given and care received; (2) to explore associations between caregiving agreement and daily caregiver depression, anxiety, and marital satisfaction; and (3) to evaluate differential effects for male and female caregivers. DESIGN: Cross-sectional, ecological assessment (daily diary). PARTICIPANTS: Sample of 191 couples aged 60 64 (total 5196 daily surveys) drawn from the longitudinal Life and Family Legacies study. MAIN MEASURES: During 2011-2012, spouses independently completed 14 consecutive daily surveys about their mood, marital interactions, and support exchanges. Caregiving agreement was defined as the daily ratio of spouse-reported care received to self-reported care given. Using generalized linear mixed effect modeling, we examined associations between spousal care agreement and outcomes of depression, anxiety, and marital satisfaction. KEY RESULTS: Sample data demonstrated broad variability in spousal agreement, with couples exhibiting substantial disagreement on nearly one-third of couple days (780/2598 days). On days where care was exchanged, higher caregiving agreement was associated with lower caregiver depression (p < 0.01) and anxiety (p < 0.01) in male caregivers, and higher marital satisfaction (p = 0.03) in female caregivers. When care recipients reported receiving more support than their spouse reported giving, these associations did not persist. CONCLUSIONS: Findings suggest that spousal agreement about the amount of care given and received varies broadly and is an important consideration for primary care providers who counsel these patients day to-day. Furthermore, agreement appears to predict mental health and relationship outcomes and should be further evaluated in this growing population of mid-to late life adults emerging into caregiving.

AB - Type 2 diabetes mellitus (T2DM) is a metabolic disorder characterized by elevated concentrations of glucose in the blood. The chronic hyperglycemic state accounts for most of the vascular complications associated to the disease and the prevalent mechanism proposed is related to the glycating chemistry mediated by methylglyoxal (MG), which accumulates in T2DM. In recent years, a higher risk of Parkinson's disease (PD) onset in people affected by T2DM has become evident, but the molecular mechanisms underlying the interplay between T2DM and PD are still unknown. The oxidative chemistry of dopamine and its reactivity towards the protein alpha-Synuclein (aS) has been associated to the pathogenesis of PD. Recently, aS has also been described to interact with MG. Interestingly, MG and the dopamine oxidation products share both structural similarity and chemical reactivity. The ability of MG to spread over the site of its production and react with aS could represent the rationale to explain the higher incidence of PD in T2DM-affected people and may open opportunities for the development of novel strategies to antagonize the raise of PD.

AB - This study examined the effects of comorbid ADHD symptoms, internalizing psychopathology, Callous-Unemotional (CU) Traits, and conduct problem severity on children's response to an evidence-based psychosocial intervention. Clinic referred children with DBD ages 8-12 years (N = 76) participated in a 15-week multi-component intervention. Parents provided weekly ratings of children's oppositionality-defiance, peer problems, and impairment. Oppositionality defiance, peer problems, and impairment decreased significantly over the course of the intervention; however, there was considerable variability in weekly ratings. Baseline ADHD symptoms, internalizing psychopathology, CU traits, and conduct problem severity were unrelated to rate of change across treatment. However, ADHD symptoms uniquely predicted more oppositionality-defiance, peer problems, and impairment averaged across the 15 weeks of treatment. Follow-up analyses suggested this was driven by hyperactivity-impulsivity rather than inattention. Children with DBD and comorbid symptoms appear to benefit from a multi-component intervention, but those with ADHD symptoms may require additional support to address social and behavioral challenges.

PMID- 29594943 TI - Bevacizumab improves survival in patients with synchronous colorectal liver metastases provided the primary tumor is resected first. AB - BACKGROUND: Multimodal strategy including chemotherapy and hepatectomy is advocated for the management of colorectal liver metastases (CRLM). The aim of this study was to evaluate the impact of neoadjuvant Bevacizumab-based chemotherapy on survival in patients with resected stage IVA colorectal cancer and liver metastases. METHODS: Data from 120 consecutive patients who received neoadjuvant chemotherapy and underwent curative-intent hepatectomy for synchronous CRLM were retrospectively reviewed. Overall survival (OS) was stratified according to administration of Bevacizumab before liver resection and surgical strategy, i.e., classical strategy (primary tumor resection first) versus reverse strategy (liver metastases resection first). RESULTS: Patients who received Bevacizumab (n = 37; 30%) had a higher number of CRLM (p = 0.003) and underwent more often reverse strategy (p = 0.005), as compared to those who did not (n = 83; 70%). Bevacizumab was associated with an improved OS compared with conventional chemotherapy (p = 0.04). After stratifying by the surgical strategy, Bevacizumab was associated with improved OS in patients who had classical strategy (p = 0.03). In contrast, Bevacizumab had no impact on OS among patients who had liver metastases resection first (p = 0.89). CONCLUSIONS: Neoadjuvant Bevacizumab-based chemotherapy was associated with improved OS in patients who underwent liver resection of synchronous CRLM, especially in those who underwent primary tumor resection first. PMID- 29594944 TI - Concurrent use of capecitabine with radiation therapy and survival in breast cancer (BC) after neoadjuvant chemotherapy. AB - PURPOSE: Capecitabine has been studied as a radiosensitizer, and our study seeks to examine the association of concurrent capecitabine/radiation therapy (RT) on event-free- (EFS) and overall survival (OS) in women with breast cancer (BC) with residual disease after neoadjuvant chemotherapy (NAC). METHODS/PATIENTS: In a retrospective study of women with BC who received adriamycin/taxane-based NAC from 2004-2016, we identified 21 women administered concurrent capecitabine/RT. To assess differences in survival, we selected a clinical control cohort (n = 57) based on criteria used to select patients for capecitabine/RT. We also created a matched cohort (2:1), matching on tumor subtype, pathological stage and age (< 50 or 50+ years). Differences in EFS, using STEEP criteria, and OS, using all-cause mortality, between those who received capecitabine/RT and controls were assessed. RESULTS: Of the 21 women who received capecitabine/RT, median age was 52 years. The majority were pathologic stage III (n = 15) and hormone receptor positive/HER2-negative BC (n = 20). In those receiving capecitabine/RT, there were 9 events, compared with 14 events in clinical and 10 events in matched controls. Capecitabine/RT was associated with worse OS in clinical (HR 3.83 95% CI 1.12-13.11, p = 0.03) and matched controls (HR 3.71 95% CI 1.04-13.18, p = 0.04), after adjusting for clinical size, pathological stage and lymphovascular invasion. Capecitabine/RT was also associated with a trend towards worse EFS in clinical (HR 2.41 95% CI 0.86-6.74, p = 0.09) and matched controls (HR 2.68 95% CI 0.91-7.90, p = 0.07) after adjustment. CONCLUSION: Concurrent capecitabine/RT after NAC is associated with worse survival and should be carefully considered in BC. PMID- 29594945 TI - Nur77 suppression facilitates androgen deprivation-induced cell invasion of prostate cancer cells mediated by TGF-beta signaling. AB - BACKGROUND: Androgen deprivation therapy (ADT) remains a standard treatment for advanced prostate cancers. However, recent studies revealed that while inhibiting the growth of certain types of prostate cancer cells, ADT promotes invasion. In the current study, we explored the effects of Nur77, an orphan nuclear receptor, on prostate cancer cell invasion following ADT. METHODS: Androgen receptor (AR) and Nur77 protein expression in patient tissues and cell lines were quantified via ELISA and western blot. The effects of AR-signaling on Nur77 expression were examined. The effects of Nur77 over-expression and knockdown on ADT-induced prostate cancer cell invasion were characterized. RESULTS: The results showed that AR and Nur77 are both highly expressed in prostate cancers of patients. Nur77 is positively regulated by AR-signaling at transcriptional level in NCI H660, a widely used prostate cancer cell line. AR antagonists, Casodex and MDV3100 treatment resulted in significant inhibition of prostate cancer cell growth but enhanced cancer cell invasion. Nur77 over-expression blocked invasion promoting effect of ADT, which is consistent with the down-regulation of MMP9 and Snail protein expression. Further mechanistic investigations showed that Nur77 inhibited transcription of TGF-beta target genes (Snail and MMP9), and thereby inhibits TGF-beta-mediated prostate cancer cell invasion following androgen antagonism. In addition, our data suggested the nature of this inhibitory effect of Nur77 on TGF-beta-signaling is selective, for Smad3-signaling, the classical effector of TGF-beta-signaling, was not interrupted by Nur77 over-expression. CONCLUSION: Considering the limited success of management of prostate cancer metastasis following ADT, our data strongly suggest that Nur77 regulation could be a promising direction for search of complementary therapeutic strategy on top of classic ADT therapy.

AB - This study was designed to investigate the mechanisms of excessive fluoride induced apoptosis via mitochondria-mediated pathway in skeletal muscle cells (C2C12 cells). C2C12 cells were cultured with the fluoride concentrations (0, 1, and 2.5 mmol/L) for 48 h. The morphology and ultrastructural changes of C2C12 cells were observed using a light microscope and transmission electron microscope (TEM). The protein expression levels of apoptosis factors, including Bax, Bcl-2, cytochrome c (Cyt c), caspase-3, and caspase-9, were measured using real-time polymerase chain reaction (real-time PCR) and immunocytofluorescence. The morphology and ultrastructure of C2C12 cells were seriously damaged by fluoride at 1 and 2.5 mmol/L doses, including swollen mitochondria, vacuolization, ridge breakage, and disappearance of the nuclear membrane. Simultaneously, compared with the control group, the expression levels of Bax, Bcl-2, Cyt c, caspase-3, and caspase-9 were up-regulated after fluoride treatment. Excessive fluoride damages the ultrastructure in mitochondria, leading to the release of Cyt c from the mitochondria to cytoplasm in C2C12 cells; thereby, activated caspases cascade apoptosis process through a mitochondria-mediated pathway. PMID- 29594947 TI - A Neuro-Comparative Study between Single/Successive Thorium Dose Intoxication and Alginate Treatment. AB - The adult male albino rats were grouped into five groups (control group and four variably treated groups with thorium (Th) in single or successive with or without alginate treatment). The IP administration of thorium nitrate (13.6 mg/kg b.wt.) induced a regional distribution and accumulation ordered as cerebellum > cerebral cortex > brain stem > hippocampus > hypothalamus > striatum. Also, it induces a significant increase in Na+, Ca2+, and Fe3+ ion content and malondialdehyde (MDA) level while K+ ions and glutathione (GSH) level were significantly decreased. On the other hand, the daily oral administration of 5% alginate showed a significant decreasing in the accumulation of thorium in the different brain areas and mitigated its hazardous effects. By the alginate treatment, Na+, Ca2+, Fe3+, and level of MDA were declined while K+ ions and GSH level showed a significant increase. The improvement of the investigated parameters was attributed to the specific chelating, regeneration, and antioxidant properties of the alginate. So, alginate administration could ameliorate the hazardous effects of thorium nitrate. PMID- 29594948 TI - Effect of Lead on Antioxidant Ability and Immune Responses of Crucian Carp. AB - The aim of this study was to explore the effects of lead exposure on the antioxidant and immune responses of Crucian carp. Three hundred sixty healthy Crucian carp were randomly grouped into four groups and exposed to different doses of lead (0, 0.05, 0.5, and 1 mg/L). Fish were sampled at 30 and 60 days, respectively, and antioxidant capability, immune parameters, ALAD activity, and immune-related genes were assessed. The results showed that T-AOC and GSH activities of the liver were significantly increased in 60 days (P < 0.05); the activities of SOD, CAT, T-AOC, and GSH were significantly increased (P < 0.05) compared to the control in the kidney in 60 days. With an increase in Pb dose, the activity and expression of lysozyme and the content of immunoglobulin M were significantly decreased compared to the control. Compared with the control group, the activity of ALAD in the lead-exposed group decreased significantly (P < 0.05). The expression of the HSP70, tumor necrosis factor-alpha (TNF-alpha), interleukins (IL-10), and immunoglobulin M genes was all enhanced in lead-exposed group, whereas lysozyme gene expression was decreased. The results indicated that lead induced oxidative stress and had immunotoxic effects on Crucian carp. PMID- 29594942 TI - The Endoplasmic Reticulum Stress Response in Neuroprogressive Diseases: Emerging Pathophysiological Role and Translational Implications. AB - The endoplasmic reticulum (ER) is the main cellular organelle involved in protein synthesis, assembly and secretion. Accumulating evidence shows that across several neurodegenerative and neuroprogressive diseases, ER stress ensues, which is accompanied by over-activation of the unfolded protein response (UPR). Although the UPR could initially serve adaptive purposes in conditions associated with higher cellular demands and after exposure to a range of pathophysiological insults, over time the UPR may become detrimental, thus contributing to neuroprogression. Herein, we propose that immune-inflammatory, neuro-oxidative, neuro-nitrosative, as well as mitochondrial pathways may reciprocally interact with aberrations in UPR pathways. Furthermore, ER stress may contribute to a deregulation in calcium homoeostasis. The common denominator of these pathways is a decrease in neuronal resilience, synaptic dysfunction and even cell death. This review also discusses how mechanisms related to ER stress could be explored as a source for novel therapeutic targets for neurodegenerative and neuroprogressive diseases. The design of randomised controlled trials testing compounds that target aberrant UPR-related pathways within the emerging framework of precision psychiatry is warranted. PMID- 29594949 TI - Characterization of multiple antibiotic resistant clinical strains of Staphylococcus isolated from pregnant women vagina. AB - Vagina which is one of the important reservoirs for Staphylococcus and in pregnant women pathogenic strains may infect the child during the birth or by vertical transmission. A total of 68 presumptive Staphylococcus strains isolated from human vagina were found to be gram-positive cocci, and only 32 (47%) isolates were found beta-hemolytic. Matrix-assisted laser desorption/ionization time-of-flight mass-spectrometry (MALDI-TOF MS) results confirmed 33 isolates belonged to Staphylococcus which consisting of 6 species, i.e., S. aureus (14), S. vitulinus (7), S. epidermidis (4), S cohnii (3), S. equorum (3), and S. succinus (2). Further, the result of antibiotic susceptibility tests showed that large proportions (76%-100%) of the isolates were resistant to multiple antibiotics and more often resistant to penicillin (100%), ampicillin (100%), oxacillin (97%), oxytetracycline (97%), vancomycin (97%), rifampin (85%), erythromycin (82%), and streptomycin (76%). In the present study, only the sec enterotoxin gene was detected in four S. aureus strains. DNA fingerprints of the 33 isolates that were generated using random amplified polymorphic DNA (RAPD) and enterobacterial repetitive intergenic consensus (ERIC) PCR analysis revealed great genetic relatedness of isolates. High prevalence of vaginal colonization with multiple antibiotic-resistant staphylococci among pregnant women was observed which were emerged from the single respective species clones that underwent evolution. The vertical transmission of these multiple antibiotic resistant Staphylococcus species to the infant is possible; therefore, the findings of this study emphasize the need for regular surveillance of antibiotic resistant bacterial strains in pregnant women in this area. PMID- 29594951 TI - Obinutuzumab with Bendamustine for Treating Follicular Lymphoma Refractory to Rituximab: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - As part of its single technology appraisal process, the UK National Institute for Health and Care Excellence (NICE) invited the manufacturer of obinutuzumab (Roche) to submit evidence on its clinical and cost effectiveness when used in combination with bendamustine in patients with follicular lymphoma (FL) refractory to rituximab. The Evidence Review Group (ERG), the School of Health and Related Research Technology Appraisal Group at the University of Sheffield, produced a document summarising the key points from the company submission alongside a critical review. Efficacy for progression-free survival (PFS) and safety was positively demonstrated in the pivotal GADOLIN trial, which compared obinutuzumab in combination with bendamustine followed by obinutuzumab maintenance (O-Benda+O) against bendamustine monotherapy. Data on overall survival were immature. The company submitted a model-based economic analysis, including a patient access scheme. The ERG identified a number of limitations, in particular the absence of subgroup analysis and the approach used by the company to estimate overall survival (OS), which was more favourable to the intervention arm. The key uncertainty was the duration of the treatment effect on OS. This uncertainty is expected to be reduced when the final analysis of the GADOLIN trial is reported. Consequently, the NICE appraisal committee recommended O Benda+O in the population covered by the marketing authorisation within the Cancer Drug Fund until NICE is able to review the guidance following publication of the final analysis of GADOLIN. PMID- 29594950 TI - The effect of human sperm chromatin maturity on ICSI outcomes. AB - Because sperm chromatin may play a key role in reproductive success, we verify the associations between sperm chromatin abnormalities, embryo development and the ability to achieve pregnancy. The evaluation of sperm chromatin maturity using aniline blue (AB), chromomycin A3 (CMA3) and toluidine blue (TB) staining were carried out in group of males from infertile couples that underwent ICSI. Low levels of sperm chromatin abnormalities (< 16%) were found in most subjects (> 50%). A higher percentage of TB-positive sperm cells were discovered in the men from couples who achieved <= 50% fertilized oocytes compared to men who achieved > 50%. No significant differences were discovered by the applied tests between the men from couples who achieved <= 50% and those who achieved > 50% high-quality embryos on the 3rd or 5th day after fertilization, nor between the men from couples who achieved pregnancy and those who failed. The sperm chromatin maturity did not correlate with the ICSI results. However, the ROC analysis revealed a significant predictive value of TB-positive spermatozoa only for fertilization. Therefore, the TB assay can be considered as a useful test for the prediction of fertilization. Our findings suggest that the level of sperm chromatin abnormalities of the examined men was not clinically significant. No found associations between sperm chromatin maturity and embryo development and the ability to achieve pregnancy. We could not exclude the effects of the repairing processes in the fertilized oocyte. The use of complementary tests that verify the status of the sperm chromatin seems justified. PMID- 29594954 TI - Irpexoates A-D, Four Triterpenoids with Malonyl Modifications from the Fruiting Bodies of the Medicinal Fungus Irpex lacteus. AB - Four eburicane-type triterpenoids with malonyl modifications, namely irpexoates A D (1-4), were isolated from the fruiting bodies of the medicinal fungus Irpex lacteus. The structures of the new compounds were established by extensive spectroscopic methods, including 1D and 2D NMR, HRESIMS spectroscopic analysis. Irpexoate B (2) displayed weak cytotoxicity against four human cancer cell lines (A-549, SMMC-7721, MCF-7, SW480) with IC50 values varying from 22.9 to 34.0 MUM, and irpexoate D (4) showed weak cytotoxicity against the human cancer cell line SW480 with an IC50 value of 35.2 MUM.

PMID- 29594952 TI - Absolute quantification of selected photosynthetic electron transfer proteins in Chlamydomonas reinhardtii in the presence and absence of oxygen. AB - The absolute amount of plastocyanin (PC), ferredoxin-NADP+-oxidoreductase (FNR), hydrogenase (HYDA1), and ferredoxin 5 (FDX5) were quantified in aerobic and anaerobic Chlamydomonas reinhardtii whole cells using purified (recombinant) proteins as internal standards in a mass spectrometric approach. Quantified protein amounts were related to the estimated amount of PSI. The ratios of PC to FNR to HYDA1 to FDX5 in aerobic cells were determined to be 1.4:1.2:0.003:0. In anaerobic cells, the ratios changed to 1.1:1.3:0.019:0.027 (PC:FNR:HYDA1:FDX5). Employing sodium dithionite and methyl viologen as electron donors, the specific activity of hydrogenase in whole cells was calculated to be 382 +/- 96.5 MUmolH2 min-1 mg-1. Importantly, these data reveal an about 70-fold lower abundance of HYDA1 compared to FNR. Despite this great disproportion between both proteins, which might further enhance the competition for electrons, the alga is capable of hydrogen production under anaerobic conditions, thus pointing to an efficient channeling mechanism of electrons from FDX1 to the HYDA1. PMID- 29594953 TI - Ceftolozane/tazobactam for the treatment of XDR Pseudomonas aeruginosa infections. AB - PURPOSE: The aim of this study was to evaluate the effectiveness of ceftolozane/tazobactam (C/T) for treating extensively drug-resistant Pseudomonas aeruginosa (XDR-PA) infections, and to analyze whether high C/T dosing (2 g ceftolozane and 1 g tazobactam every 8 h) and infection source control have an impact on outcome. METHODS: Retrospective study of all consecutive patients treated with C/T for XDR-PA infection at a tertiary referral hospital (November 2015-July 2017). Main clinical and microbiological variables were analyzed. RESULTS: Thirty-eight patients were included. Median age was 59.5 years and Charlson Comorbidity Index was 3.5. Fourteen (36.8%) patients had respiratory tract infection, six (15.8%) soft tissue, and six (15.8%) urinary tract infection. Twenty-three (60.5%) received high-dose C/T and in 24 (63.2%) C/T was combined with other antibiotics. At completion of treatment, 33 (86.8%) patients showed clinical response. At 90 days of follow-up, 26 (68.4%) achieved clinical cure, and 12 (31.6%) had clinical failure because of persistent infection in one patient, death attributable to the XDR-PA infection in four, and clinical recurrence in seven. All-cause mortality was 5 (13.2%). Lower C/T MIC and adequate infection source control were the only variables significantly associated with clinical cure. CONCLUSIONS: C/T should be considered for treating XDR-PA infections, with infection source control being an important factor to avoid failure and resistance. PMID- 29594956 TI - Mechanisms and Effects on HBV Replication of the Interaction between HBV Core Protein and Cellular Filamin B. AB - Hepatitis B virus (HBV) infection is one of the major problems that threatens global health. There have been many studies on HBV, but the relationship between HBV and host factors is largely unexplored and more studies are needed to clarify these interactions. Filamin B is an actin-binding protein that acts as a cytoskeleton protein, and it is involved in cell development and several signaling pathways. In this study, we showed that filamin B interacted with HBV core protein, and the interaction promoted HBV replication. The interaction between filamin B and core protein was observed in HEK 293T, Huh7 and HepG2 cell lines by co-immunoprecipitation and co-localization immnofluoresence. Overexpression of filamin B increased the levels of HBV total RNAs and pre-genome RNA (pgRNA), and improved the secretion level of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg). In contrast, filamin B knockdown inhibited HBV replication, decreased the level of HBV total RNAs and pgRNA, and reduced the secretion level of HBsAg and HBeAg. In addition, we found that filamin B and core protein may interact with each other via four blocks of argentine residues at the C-terminus of core protein. In conclusion, we identify filamin B as a novel host factor that can interact with core protein to promote HBV replication in hepatocytes. Our study provides new insights into the relationship between HBV and host factors and may provide new strategies for the treatment of HBV infection. PMID- 29594957 TI - Exhaustive Exercise Does Not Affect Humoral Immunity and Protection after Rabies Vaccination in a Mouse Model. AB - Rabies is one of the most dangerous and widespread zoonosis and is characterized by severe neurological signs and a high case-mortality rate of nearly 100%. Vaccination is the most effective way to prevent rabies in humans and animals. In this study, the relationship between exhaustive exercise and the humoral immune response after immunization with inactivated rabies vaccine was investigated in a mouse model with one-time exhaustive exercise. It was found that compared with the mice with no exercise after vaccination, no significant differences were found in those with exhaustive exercise after vaccination on body-weight changes, virus-neutralizing antibody (VNA) titers, antibody subtypes and survivor ratio after lethal rabies virus (RABV) challenge. This study indicated that exhaustive exercise does not reduce the effects of the rabies inactivated vaccine. PMID- 29594958 TI - Change of Direction Speed: Toward a Strength Training Approach with Accentuated Eccentric Muscle Actions. AB - There is growing evidence that eccentric strength training appears to have benefits over traditional strength training (i.e., strength training with combined concentric and eccentric muscle actions) from muscular, neuromuscular, tendinous, and metabolic perspectives. Eccentric muscle strength is particularly needed to decelerate and stabilize the body during the braking phase of a jump exercise or during rapid changes of direction (CoD) tasks. However, surprisingly little research has been conducted to elucidate the effects of eccentric strength training or strength training with accentuated eccentric muscle actions on CoD speed performance. In this current opinion article, we present findings from cross-sectional studies on the relationship between measures of eccentric muscle strength and CoD speed performance. In addition, we summarize the few available studies on the effects of strength training with accentuated eccentric muscle actions on CoD speed performance in athletic populations. Finally, we propose strength training with accentuated eccentric muscle actions as a promising element in strength and conditioning programs of sports with high CoD speed demands. Our findings from five cross-sectional studies revealed statistically significant moderate- to large-sized correlations (r = 0.45-0.89) between measures of eccentric muscle strength and CoD speed performance in athletic populations. The identified three intervention studies were of limited methodological quality and reported small- to large-sized effects (d = 0.46-1.31) of strength training with accentuated eccentric muscle actions on CoD speed performance in athletes. With reference to the available but preliminary literature and from a performance-related point of view, we recommend strength and conditioning coaches to include strength training with accentuated eccentric muscle actions in training routines of sports with high CoD speed demands (e.g., soccer, handball, basketball, hockey) to enhance sport-specific performance. Future comparative studies are needed to deepen our knowledge of the effects of strength training with accentuated eccentric muscle actions on CoD speed performance in athletes.

PMID- 29594961 TI - Comparative performance of dairy cows in low-input smallholder and high-input production systems in South Africa. AB - The aim of this study was to benchmark the performance of dairy cows in the low input smallholder system against their counterparts in the high-input system, in South Africa. Data comprised of cow performance records from the national dairy recording scheme. Performance measures included production (305-day yields of milk, fat, and protein), lactation length, somatic cell count (SCC), and reproductive traits, represented by age at first calving (AFC) and calving interval (CI). Least squares means of each trait were compared between the two systems, and lactation curves for production traits and SCC were plotted for each production system. Mean yields of milk, fat, and protein were significantly (P < 0.05) lower in the smallholder (4097 +/- 165, 174 +/- 5.1, and 141 +/- 4.5 respectively) compared to the high-input system (6921 +/- 141, 298 +/- 4.7, and 245 +/- 4.1 respectively). Mean lactation length was significantly (P < 0.05) shorter for the smallholder (308 +/- 15.1) than the high-input system (346 +/- 12.8). Log-transformed somatic cell count (SCS) was, however, significantly (P < 0.05) higher in the smallholder (2.41 +/- 0.01) relative to the high-input system (2.27 +/- 0.01). Cows in high-input herds showed typical lactation curves, in contrast to the flat and low peaking curves obtained for the smallholder system. Cows on smallholder herds had their first calving significantly (P < 0.05) older (30 +/- 0.5) than those in the high-input system (27 +/- 0.5). There was, however, no significant difference (P < 0.05) in CI between the two systems. These results highlight large room for improvement of dairy cow performance in the smallholder system and could assist in decision-making aimed at improving the productivity of the South African dairy industry. PMID- 29594962 TI - Influence of distance to urban markets on smallholder dairy farming systems in Kenya. AB - We studied influence of distance to urban markets on smallholder dairy farming system development. Farms were chosen from three locations that varied in distance to the urban market of Nakuru Town in the Kenyan highlands: urban location (UL, n = 10) at less than 15 km distance, mid-rural location (MRL, n = 11) in between 20 and 50 km west of Nakuru and extreme rural location (ERL, n = 9) beyond 50 km west and south-west of Nakuru. In-depth interviews with farmers and focus group discussions with eight groups of stakeholders were held to collect narratives and data about market quality, production factors, farm performance and functions of dairy cattle. We applied thematic content analysis to qualitative information by clustering narratives according to predefined themes and used ANOVA to analyse farm data. In UL, markets were functional, with predominantly informal market chains, with a high milk price (US $ 45.1/100 kg). Inputs were available in UL markets, but prices were high for inputs such as concentrates, fodder, replacement stock and hired labour. Moreover, availability of grazing land and the high opportunity costs for family labour were limiting dairy activities. In UL, milk production per cow (6.9 kg/cow/day) and per farm (20.1 kg/farm/day) were relatively low, and we concluded that farm development was constrained by scarcity of inputs and production factors. In rural locations (MRL and ERL), markets were functional with relatively low prices (average US $ 32.8/100 kg) for milk in both formal and informal market chains. Here, concentrates were relatively cheap but also of low quality. Fodder, replacement stock and labour were more available in rural locations than in UL. In rural locations, milk production per cow (average 7.2 kg/cow/day) and per farm (average 18.5 kg/farm/day) were low, and we concluded that farm development was constrained by low quality of concentrates and low price of milk. In all locations, production for subsistence was valued since income generated was used for non-dairy expenses. A tailor-made package of interventions that targets the above constraints is recommended for farm development. PMID- 29594963 TI - The effects of PPR on the reproductive health of Black Bengal goats and the possible role played by oxidative stress. AB - Outbreaks of Peste des petits ruminants (PPR) viral disease in Black Bengal goats were investigated from the middle Indo-Gangetic Plains of India. Clinical profile of PPR-affected flocks was recorded from four different outbreak sites of the region. The PPR outbreak was diagnosed serologically using commercially available sandwich ELISA kit. Relatively, low mortality rate (mean 26.75%) for PPR outbreak was recorded due to the endemic status of the disease. To understand the role of oxidative stress in PPR virus pathogenesis, various oxidant and antioxidant parameters in goats infected with PPR were estimated and compared with the uninfected/healthy goats of the same flock. The measured high level of pro oxidant malondialdehyde (MDA) obtained from lipid peroxidation along with lower levels of anti-oxidants viz. superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) in PPR-affected Black Bengal goats suggests oxidative stress as one of the mechanism of pathogenesis of PPR virus. In addition, the correlation of oxidative stress due to PPR and the resulting reproductive disorders in the female goats were evaluated. The abortion in pregnant does observed during PPR outbreak was proportional to debility and oxidative stress manifested during PPR infection. The reproductive performance of recovered female goats in the period of 18 months of monitoring was significantly compromised in terms of kidding and twinning frequency. The mortality rate in kids born from PPR recovered goats was significantly higher compared to those from health goats in the first 9 months post-recovery. From the present study, it may be concluded that together with the PPR virus, infection in goats and the resulting oxidative stress play a vital role for abortion and reduced post-reproductive performance in Black Bengal female goat. PMID- 29594965 TI - Quality of life in patients with MuSK positive myasthenia gravis. AB - It is believed that myasthenia gravis (MG) with antibodies to muscle-specific tyrosine kinase (MuSK) is the most severe form of the disease, especially in the first years of the disease. The aim of our study was to investigate quality of life (QoL) in a population of patients with MuSK MG compared to those with MG who have antibodies to acetylcholine receptor (AChR) in their sera. The study group consisted of 35 MuSK MG patients (28 females and 7 males), while the control group included 38 AChR MG patients matched for gender, age, and duration of the disease. SF-36 questionnaire was used to evaluate the health-related QoL. Following scales were also used: Hamilton's scales for depression and anxiety, the Multidimensional Scale of Perceived Social Support, and the Acceptance of Illness Scale. Physical domain scores of QoL were similarly affected in both MuSK and AChR groups, while mental domain and total SF-36 scores were even better in MuSK MG patients. Social support was better in the MuSK group (77.3 +/- 9.3 vs. 70.6 +/- 14.1, p < 0.05). SF-36 total score correlated with depression (rho = 0.54, p < 0.01), anxiety (rho = 0.49, p < 0.01), and MSPSS (rho = - 0.35, p < 0.05), and depression was an independent predictor of worse QoL. Besides therapy of weakness, psychiatric treatment and different forms of psychosocial condition should be part of regular therapeutic protocols for MG. Adequate team work of health professionals and family can provide a healthy mental environment in which a MuSK MG patient would feel more comfortable in spite of the disease. PMID- 29594966 TI - T cell receptor-beta J usage, in combination with particular HLA class II alleles, correlates with better cancer survival rates. AB - T cell receptor (TCR) beta V and J usage correlates with either the HLA class I or HLA class II major histocompatibility subtypes, and in both infectious diseases and autoimmune settings, the use of particular TCR-beta V and J's, in persons with specific HLA alleles, represents either better outcomes or certain clinical features. However, the relationship of TCR V and J usage, HLA alleles, and clinical parameters in the cancer setting has been less well studied. Here, we have evaluated the relationship of what is likely dominant TCR-beta V and J usage among tissue-resident lymphocytes for lung, head and neck, kidney, stomach, ovarian, and endometrial cancers, with patient HLA class II alleles. The most striking indication is that TCR-beta J subgroup usage, in combination with particular patient HLA class II alleles, correlated with either better or worse outcomes for lung cancer. One combination, TCR-beta J2 segment usage and the HLA DRB1*1501 allele, correlated with a better survival rate for both lung and head and neck cancers. These results fill a gap in knowledge regarding the relevance of HLA typing to cancer and indicate that HLA typing, along with an indication of dominant TCR-beta J usage among tissue-resident lymphocytes, can be useful for prognosis. PMID- 29594964 TI - CVIT expert consensus document on primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) in 2018. AB - While primary percutaneous coronary intervention (PCI) has significantly contributed to improve the mortality in patients with ST segment elevation myocardial infarction even in cardiogenic shock, primary PCI is a standard of care in most of Japanese institutions. Whereas there are high numbers of available facilities providing primary PCI in Japan, there are no clear guidelines focusing on procedural aspect of the standardized care. Whilst updated guidelines for the management of acute myocardial infarction were recently published by European Society of Cardiology, the following major changes are indicated; (1) radial access and drug-eluting stent over bare metal stent were recommended as Class I indication, and (2) complete revascularization before hospital discharge (either immediate or staged) is now considered as Class IIa recommendation. Although the primary PCI is consistently recommended in recent and previous guidelines, the device lag from Europe, the frequent usage of coronary imaging modalities in Japan, and the difference in available medical therapy or mechanical support may prevent direct application of European guidelines to Japanese population. The Task Force on Primary Percutaneous Coronary Intervention of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document for the management of acute myocardial infarction focusing on procedural aspect of primary PCI. PMID- 29594967 TI - Fecal Microbiome Among Nursing Home Residents with Advanced Dementia and Clostridium difficile. AB - BACKGROUND/OBJECTIVES: Patients colonized with toxinogenic strains of Clostridium difficile have an increased risk of subsequent infection. Given the potential role of the gut microbiome in increasing the risk of C. difficile colonization, we assessed the diversity and composition of the gut microbiota among long-term care facility (LTCF) residents with advanced dementia colonized with C. difficile. DESIGN: Retrospective analysis of rectal samples collected during a prospective observational study. SETTING: Thirty-five nursing homes in Boston, Massachusetts. PARTICIPANTS: Eighty-seven LTCF residents with advanced dementia. MEASUREMENTS: Operational taxonomic units were identified using 16S rRNA sequencing. Samples positive for C. difficile were matched to negative controls in a 1:3 ratio and assessed for differences in alpha diversity, beta diversity, and differentially abundant features. RESULTS: Clostridium difficile sequence variants were identified among 7/87 (8.04%) residents. No patient had evidence of C. difficile infection. Demographic characteristics and antimicrobial exposure were similar between the seven cases and 21 controls. The overall biodiversity among cases and controls was reduced with a median Shannon index of 3.2 (interquartile range 2.7-3.9), with no statistically significant differences between groups. The bacterial community structure was significantly different among residents with C. difficile colonization versus those without and included a predominance of Akkermansia spp., Dermabacter spp., Romboutsia spp., Meiothermus spp., Peptoclostridium spp., and Ruminococcaceae UGC 009. CONCLUSION: LTCF residents with advanced dementia have substantial dysbiosis of their gut microbiome. Specific taxa characterized C. difficile colonization status. PMID- 29594968 TI - Profiles of Patients Who Use Marijuana for Inflammatory Bowel Disease. AB - BACKGROUND: Marijuana is legal in a number of states for indications that include inflammatory bowel diseases (IBD), and patients are interested in its potential benefits. AIMS: We aimed to describe the legal use of marijuana in individuals with IBD in the USA who participate within the CCFA Partners internet-based cohort. METHODS: A total of 2357 participants who lived in states where prescription or recreational marijuana was legal, were offered the opportunity to complete a survey on marijuana use and IBD symptoms including perceived benefits of therapy. Bivariate statistics and logistic regression models were used to determine factors associated with marijuana use. RESULTS: Surveys were completed by 1666 participants (71%) with only 214 (12.8%) indicating they had asked their medical doctor about its use and 73 actually using prescribed marijuana (4.4%). Within the respondent group (N = 1666), 234 participants lived where both medical and recreational marijuana is legal and 49 (20.9%) reported recreational marijuana use specifically for IBD. Users reported positive benefits (80.7%), but users also reported more depression, anxiety, pain interference, and lower social satisfaction than non-users. Those prescribed marijuana reported more active disease, and more use of steroids, narcotics, and zolpidem. CONCLUSIONS: Few IBD patients consulted their medical doctors about marijuana use or used prescription marijuana. Where recreational marijuana was available, usage rates were higher. Users reported benefits but also more IBD symptoms, depression, anxiety, and pain. Marijuana use may be higher in patients with IBD symptoms not well treated by conventional medical approaches. PMID- 29594969 TI - Hepatic Encephalopathy and Helicobacter pylori. PMID- 29594970 TI - Lower Sustained Diphtheria and Pertussis Antibody Concentrations in Inflammatory Bowel Disease Patients. AB - BACKGROUND: Patients with inflammatory bowel disease (IBD) are often immunosuppressed, and those patients receiving anti-tumor necrosis factor alpha (TNF) therapy can have lower antibody responses to vaccines. Pertussis cases are at their highest levels in the post-vaccine era. There is little data regarding responses to the Tdap (tetanus, diphtheria, and acellular pertussis) vaccine in IBD patients. AIMS: The aim of this study was to compare sustained vaccine induced Tdap antibody concentrations in a cohort of IBD patients stratified by medication regimens with healthy controls (HC) who had received an adult Tdap booster. METHODS: We performed a cross-sectional study evaluating antibody responses to Tdap vaccine among IBD patients compared to HC. Our study consisted of three patient groups: adults with IBD stratified by maintenance medication regimen: (1) thiopurine monotherapy; (2) anti-TNF monotherapy; and (3) combination therapy (anti-TNF and immunomodulator (thiopurine or methotrexate)). RESULTS: Ninety IBD patients and 20 HC participated. Pertussis pertactin antibody concentrations were significantly lower in IBD patients (p = 0.021) compared to HC, and those on anti-TNF agents (monotherapy or combination) had lower antibody concentrations compared to those on thiopurine monotherapy (p = 0.028). Diphtheria antibody concentrations were also lower in IBD patients (p < 0.001), and those on anti-TNF agents (monotherapy or combination) had lower antibody concentrations compared to the thiopurine monotherapy group (p < 0.001). CONCLUSION: IBD patients on anti-TNF agents had lower antibody concentrations to diphtheria and pertussis. These findings suggest a need for different Tdap booster schedules for IBD patients on anti-TNF therapy. Clinical Trials Registry NCT02434133. PMID- 29594971 TI - Association between malocclusion and dental caries in adolescents: a systematic review and meta-analysis. AB - AIM: To evaluate the scientific evidence regarding the association between malocclusion and dental caries in adolescents. METHODS: Searches were conducted of six electronic databases, complemented by manual searching of the reference lists of the selected articles and grey literature. Two independent reviewers performed the selection of the articles, data extraction and the evaluation of the risks of bias through an assessment of methodological quality. Meta-analysis was performed considering the mean decayed, missing and filled teeth (DMFT) index for caries and the Dental Aesthetic Index (DAI) for malocclusion. Heterogeneity was tested using the I2 statistic and a random effect model was employed. Summary effect measures were calculated as differences in means. RESULTS: The initial search retrieved 2644 studies, only 15 of which were selected for full-text analysis. Four cross-sectional studies were included in the qualitative systematic review. Only one of these studies found no association between malocclusion and dental caries. The meta-analysis of three studies demonstrated that a lower DAI value was significantly associated with a lower mean DMFT index, except for the comparison of DAI 26-30 vs. 31-35. CONCLUSIONS: Based on the studies analysed, the scientific evidence indicates an association between malocclusion and dental caries. PMID- 29594973 TI - Clinical and Therapeutic Aspects of Linear Psoriasis: A Study of 30 Cases. AB - BACKGROUND: Psoriasis affects 2-4% of the population, with the most common clinical type being plaque psoriasis. The linear form of psoriasis is very rare. The literature on linear psoriasis (LP) consists of only case reports, and data are few. OBJECTIVE: This study aimed to better understand LP in a large-scale study. PATIENTS AND METHODS: We retrospectively retrieved the medical records from 14 French medical centers of patients newly diagnosed clinically with LP, with or without the support of histology, between 1 February and 31 July 2015. For each case, we assessed the clinical features, treatments and treatment efficacy. RESULTS: In total, 30 cases of LP (mean age 26.8 years, 13 males) were reported. Mean age at onset of LP was 20.0 years, with 18 developing LP in childhood. Ten patients had a family history of psoriasis, and two had psoriatic arthritis. A total of 19 cases were linear at onset, with concomitant classical psoriasis; these were termed "superimposed" LP. The remaining 11 cases were not associated with classical psoriasis and were termed "isolated" LP. In four of the superimposed cases, LP developed when the patient was receiving systemic treatment: methotrexate (n = 2), etanercept (n = 1) or infliximab (n = 1). Topical steroids were effective in 76% of cases in which they were used, and systemic treatment was effective in < 66%. Treatments were less effective in LP than in classical psoriasis. DISCUSSION: We identified a wide range of LP, with two profiles: isolated LP and superimposed LP. Topical treatment usually evoked clinical response, with relative resistance to systemic therapy. Methotrexate and anti-tumor necrosis factor (TNF)-alpha therapies can possibly unmask LP. PMID- 29594972 TI - A Pharmacological Rationale to Reduce the Incidence of Opioid Induced Tolerance and Hyperalgesia: A Review. AB - Chronic pain is an important health and social problem. Misuse and abuse of opioids in chronic non-cancer pain management seem to be a huge problem, in some countries. This could probably affect the normal use of such analgesics in patients in need of them. Basic and clinical researches should find the solution to mitigate the potential damage. Dysregulation of mast cell and microglia activation plays an important role in the pathogenesis and management of chronic pain. Persistent mast cell activation sensitizes nociceptors and initiates central nervous system inflammatory processes, involving microglial cell activation and sensitization of spinal somatosensory neurons. Exposure of mast cells and microglia to opioids is well known to provoke activation of these non neuronal immune cell populations, thereby contributing to an exacerbation of pro inflammatory and pro-nociceptive processes and promoting, over the long-term, opioid-induced hyperalgesia and tolerance. This review is intended to provide the reader with an overview of the role for these non-neuronal cells in opioid induced chronic pain and tolerance as a consequence of prolonged exposure to these drugs. In addition, we will examine a potential strategy with the aim to modulate opioid-induced over-activation of glia and mast cells, based on endogenous defense mechanisms and fatty acid amide signaling molecules.

AB - As we gain a greater understanding of acne pathogenesis, both new agents as well as new uses for established drugs are being considered for the treatment of acne vulgaris. Multiple clinical trials assessing new formulations or combinations of established acne treatments have been conducted, and novel uses of antimicrobials such as modified diallyl disulfide oxide and nitric oxide are being assessed in clinical trials. There are also a multitude of new therapies currently being studied that target the inflammatory cascade of acne pathogenesis, including sebosuppressive and anti-inflammatory phytochemicals, and small molecule inhibitors targeting sebaceous glands and enzymes, among others. Laser and light therapy is also being modified for the treatment of acne through combination methods with metal nanoshells and vacuum assistance. Probiotics have gained popularity in medicine as greater knowledge of the microbiome and its effects on multiple organ systems is being elucidated. Studies describing the positive effects of certain ammonia-oxidizing bacterial strains in the regulation of the skin's inflammatory response are ongoing. Therapies for acne are constantly evolving and current gold-standard acne therapy may be supplemented with novel treatment modalities in the near future. PMID- 29594975 TI - Hispanic Americans and Non-Hispanic White Americans Have a Similar Inflammatory Bowel Disease Phenotype: A Systematic Review with Meta-Analysis. AB - BACKGROUND: Inflammatory bowel disease (IBD) is a devastating immune-mediated disease on the rise in Hispanics living in the USA. Prior observational studies comparing IBD characteristics between Hispanics and non-Hispanic whites (NHW) have yielded mixed results. AIMS: We performed a meta-analysis of observational studies examining IBD phenotype in Hispanics compared to NHW. METHODS: We conducted a systematic search of US-based studies comparing IBD subtype (Ulcerative Colitis: UC or Crohn's disease: CD) and phenotype (disease location and behavior) between Hispanics and NHW. We evaluated differences in age at IBD diagnosis, the presence of family history and smoking history. A random effects model was chosen "a priori." Categorical and continuous variables were analyzed using odds ratio (OR) or standard mean difference (SMD), respectively. RESULTS: Seven studies were included with 687 Hispanics and 1586 NHW. UC was more common in Hispanics compared to NHW (OR 2.07, CI 1.13-3.79, p = 0.02). Location of disease was similar between Hispanics and NHW except for the presence of upper gastrointestinal CD, which was less common in Hispanics (OR 0.58, CI 0.32-1.06, p = 0.07). Hispanics were less likely to smoke (OR 0.48, CI 0.26-0.89, p = 0.02) or have a family history of IBD (OR 0.35, CI 0.22-0.55, p < 0.001). CD behavior classified by Montreal classification and age at IBD diagnosis were similar between Hispanics and NHW. CONCLUSION: UC was more common among US Hispanics compared to NHW. Age at IBD diagnosis is similar for both Hispanics and NHW. For CD, disease behavior is similar, but Hispanics show a trend for less upper gastrointestinal involvement. A family history of IBD and smoking history were less common in Hispanics. PMID- 29594977 TI - Low Prevalence of Biopsy-Proven Eosinophilic Esophagitis in Patients with Esophageal Food Impaction in Mexican Population. AB - BACKGROUND: Eosinophilic esophagitis (EoE) is the most common cause of dysphagia and esophageal food impaction (EFI) in the USA, Western Europe, and Australia. In Mexico, the uncomplicated form of this disease is infrequent, and prevalence in patients with EFI is unknown. AIMS: To determine the prevalence and causes of EFI, endoscopic and therapeutic aspects, and establish the prevalence of biopsy proven EoE in patients with EFI. METHODS: Diagnostic upper gastrointestinal endoscopy reports from January 2011 to December 2016 were retrospectively reviewed. Patients with therapeutic procedures, gastrointestinal hemorrhage, or non-food foreign body impaction were excluded. The number of patients with EFI was determined. Additionally, patients with esophageal biopsy were retained for EoE prevalence calculation. The diagnosis of EoE was defined with the presence of eosinophil infiltration count >= 15/high-power field with or without typical endoscopic abnormalities. RESULTS: A total of 4700 reports of the same number of patients were selected; 2209 were males (47%) with a mean age of 57.6 +/- 12.3 years (range 14-93). We identified 36 patients with EFI (0.76, 95% CI 0.51-1.01), 16 males (44.4%) with a mean age of 54.9 +/- 19.7 (range 22-92). Esophageal biopsies were obtained in 17/36 (47.2%) cases. The diagnosis of EoE was confirmed in 2 patients (11.7%). Peptic stenosis was the most frequent cause of EFI. CONCLUSIONS: EoE is an infrequent cause of EFI in the Mexican population (11.7%). EoE had the lowest prevalence compared to that reported in Caucasian populations. The prevalence of EFI was also low.

PMID- 29594976 TI - Efficacy of a Dexmedetomidine-Remifentanil Combination Compared with a Midazolam Remifentanil Combination for Conscious Sedation During Therapeutic Endoscopic Retrograde Cholangio-Pancreatography: A Prospective, Randomized, Single-Blinded Preliminary Trial. AB - BACKGROUND: Dexmedetomidine as a conscious sedative exhibits both analgesia and respiratory sparing effects. AIMS: We evaluated and compared the sedative effect and the safety of a dexmedetomidine-remifentanil (DR) regimen with a midazolam remifentanil (MR) combination during the endoscopic retrograde cholangio pancreatography (ERCP) requiring conscious sedation. METHODS: One-hundred and ninety-eight patients were randomized and divided into two groups. A bolus of midazolam (0.05 mg kg-1) was injected intravenously for MR group, and dexmedetomidine (1 MUg kg-1) was pumping for 10 min for DR group. Next, an initial loading dose of 1 MUg kg-1 and 0.05-0.2 MUg kg-1 min-1 of remifentanil was administered in all patients. Hemodynamic and respiratory changes, Ramsay Sedation Scale, Visual Analogue Scale, endoscopist and patient satisfaction were assessed. Furthermore, adverse events as well as recovery time and discharge time were rated. RESULTS: Patient satisfaction scores were significantly higher in the DR group compared with MR group. The occurrence of desaturation was statistically higher, and the operation time was longer in the MR group. Although no statistically significant values could be determined between the two groups about amnesia and need of additional drug, the DR group was found to require a significantly reduced amount of extra midazolam. Furthermore, nausea during catheterization of oropharynx was found to be more pronounced in the DR group. CONCLUSIONS: The dexmedetomidine-remifentanil protocol provided a parallel sedative efficacy and improved respiratory sparing effects. The higher patient satisfaction scores potentially offer a more reproducible ERCP quality. Adding dexmedetomidine to remifentanil can be used safely as a conscious sedation method during ERCP. PMID- 29594979 TI - Anti-inflammatory and Antioxidant Effects of Captopril Compared to Methylprednisolone in L-Arginine-Induced Acute Pancreatitis. AB - BACKGROUND: Acute pancreatitis (AP) is an inflammatory disease mediated by damage in acinar cells and pancreatic inflammation with infiltration of leukocytes. The pancreatic renin-angiotensin system may play an important role in the pathogenesis of AP. AIM: The present study aimed to investigate the possible protective role of captopril (CAP), an angiotensin-converting enzyme inhibitor, in attenuating L-arginine-induced AP rat model and to elucidate the underlying molecular mechanisms. METHODS: Forty-eight adult male Wister rats were divided into four equal groups: control group (vehicle, orally for 10 days), AP group (3 g/kg L-arginine, single i.p.) on 10th day of the experiment, CAP group (50 mg/kg captopril, orally, once daily), and MP group (30 mg/kg methylprednisolone, orally, once daily). CAP and MP were administered for 10 days prior to L-arginine injection. Rats were sacrificed 24 h after arginine injection. Inflammatory biomarkers; tumor necrosis factor alpha (TNF-alpha) concentration, myeloperoxidase (MPO) activity, and inducible nitric oxide synthase (iNOS) gene expression were determined in pancreas. Oxidative stress biomarkers; pancreatic nitric oxide (NO) and reduced glutathione (GSH) concentrations were measured. Moreover, serum alpha-amylase and lipase activities were measured and histopathological studies of the pancreas were done. RESULTS: CAP group showed a significant reduction in pancreatic TNF-alpha concentration, MPO activity, NO concentration, and downregulation of iNOS gene expression compared to AP group. CAP group also showed a significant increase in GSH concentration with amelioration of histological changes of AP as well as MP group. CONCLUSION: Captopril treatment showed a protective and comparable effect with MP treatment in AP rat model. PMID- 29594981 TI - History solves the mystery: an unusual cause of hypercalcemia. PMID- 29594980 TI - Is Young Adulthood a Critical Period for Suicidal Behavior among Sexual Minorities? Results from a US National Sample. AB - The developmental timing of suicide-related disparities between heterosexuals and sexual minorities (i.e., lesbian/gay and bisexual (LGB) people) is an understudied area that has critical prevention implications. In addition to developmentally situated experiences that shape risk for suicidality in the general population, sexual minorities also experience unique social stressors (e.g., anti-LGB stigma) that may alter their risk for suicidal behavior at different ages. Using a nationally representative US sample of adults, we assessed age-varying rates of suicidal behavior among heterosexuals and sexual minorities ages 18 to 60 and the age-varying association between anti-LGB discrimination and suicidal behavior. We also tested whether these age-varying prevalences and associations differed for men and women and for sexual minorities who did and did not endorse a sexual minority identity. Results indicate a critical period for suicide behavior risk for sexual minorities during young adulthood, with the highest rates of risk at age 18 followed by a steady decline until the early 40s. Disparities were particularly robust for sexual minorities who identified as lesbian, gay, or bisexual. This pattern was present for both men and women, though sexual minority women in their 30s were more likely to report suicidal behavior than heterosexuals and sexual minority men. Sexual minorities who experienced anti-LGB discrimination were more likely to report suicidal behavior, but the significance of this association was limited to those under 30. The effect of discrimination on suicidal behavior was stronger among young adult sexual minority men, relative to sexual minority women, but was present for a wider age range for sexual minority women (until age 30) relative to sexual minority men (until age 25). PMID- 29594982 TI - Penile calciphylaxis in a patient on combined peritoneal dialysis and hemodialysis. AB - Calciphylaxis presents with painful purpura and intractable skin ulcers on the trunk and particularly the distal extremities, and it mainly occurs in patients on chronic dialysis. A 66-year-old man with renal failure due to diabetic nephropathy was on peritoneal dialysis alone for 1 year, followed by peritoneal dialysis combined with hemodialysis for 3 years. He developed calciphylaxis of the penis, which was diagnosed from the skin biopsy findings and clinical observation. To treat this condition, PD was stopped and HD was performed three times a week. In addition, warfarin therapy was discontinued and infusion of sodium thiosulfate was performed. The penile ulcers decreased in size and pain was markedly improved, so the patient was discharged from hospital. Following discharge, PD was resumed after changing the peritoneal dialysis fluid to bicarbonate-buffered dialysate. The penile ulcers eventually resolved completely. There have been very few reports about calciphylaxis in patients on combined dialysis modalities. In our patient, penile calciphylaxis progressed when lactate buffered peritoneal dialysis fluid was used and resolved after switching to bicarbonate-buffered fluid together with cessation of warfarin therapy and infusion of sodium thiosulfate. PMID- 29594983 TI - Persistent EcoHIV infection induces nigral degeneration in 1-methyl-4-phenyl 1,2,3,6-tetrahydropyridine-intoxicated mice. AB - The widespread use of antiretroviral therapy for treatment of human immunodeficiency virus (HIV) infections has dramatically improved the quality and duration of life for HIV-positive individuals. Despite this success, HIV persists for the life of an infected person in tissue reservoirs including the nervous system. Thus, whether HIV exacerbates age-related brain disorders such as Parkinson's disease (PD) is of concern. In support of this idea, HIV infection can be associated with motor and gait abnormalities that parallel late-stage manifestations of PD including dopaminergic neuronal loss. With these findings in hand, we investigated whether viral infection could affect nigrostriatal degeneration or exacerbate chemically induced nigral degeneration. We now demonstrate an additive effect of EcoHIV on dopaminergic neuronal loss and neuroinflammation induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine intoxication. HIV-1-infected humanized mice failed to recapitulate these EcoHIV results suggesting species-specific neural signaling. The results demonstrate a previously undefined EcoHIV-associated neurodegenerative response that may be used to model pathobiological aspects of PD. PMID- 29594984 TI - In vivo characterization of macrophage-tropic simian immunodeficiency virus molecular clones in rhesus macaques. AB - Macrophages are a major target of HIV/SIV infection and play an important role in pathogenesis by serving as viral reservoirs in the central nervous system. Previously, a unique early SIVmac251 envelope (Env) variant, deSIV147 was cloned from blood of a rhesus macaque with rapid disease progression and SIV-associated encephalitis. Here, we show that infectious molecular clone deSIV147 caused systemic infection in rhesus macaques following intravenous or intrarectal exposure. Next, we inoculated deSIV147 into macaques depleted of CD4+ T cells and found that animals were SIV-positive, with high plasma and CSF viral loads. These macaques also showed SIVp17-positive macrophages in brain, lymph nodes, colon, lung, and liver. Furthermore, accumulation of perivascular macrophages, multinucleated giant cells, and microgliosis was detected. These findings suggest that the neurotropic deSIV147 clone will be useful to study macrophage infection in HIV/SIV-associated neurocognitive disorders, gain insights into myeloid cell reservoirs in brain and other anatomical sites, as well as test strategies for eradication. PMID- 29594985 TI - Zika virus outbreak in New Caledonia and Guillain-Barre syndrome: a case-control study. AB - Zika virus (ZIKV) infection has been associated with neurologic disorders including Guillain-Barre syndrome (GBS). In New Caledonia during the ZIKV outbreak (2014-2015), case-control and retrospective studies have been performed to assess the link between ZIKV and GBS. Among the 15 cases included, 33% had evidence of a recent ZIKV infection compared to only 3.3% in the 30 controls involved. All patients were Melanesian, had facial diplegia and similar neurophysiological pattern consistent with acute inflammatory demyelinating polyneuropathy, and recovered well. Furthermore, during the peak of ZIKV transmission, we observed a number of GBS cases higher than the calculated upper limit, emphasizing the fact that ZIKV is now a major trigger of GBS. PMID- 29594988 TI - [Association between the dental caries and the human leucocyte antigen DQB1 allele polymorphisms among the Uygur and Han children in Xinjiang]. AB - OBJECTIVE: This study aims to investigate the association between human leucocyte antigen (HLA)-DQB1 allele polymorphisms and the presence dental caries among the Uygur and Han children in Xinjiang. METHODS: HLA-DQB1 allele in the Uygur and Han children with dental caries and healthy control in Xinjiang was tested (n=40) using the polymerase chain reaction-sequence specific primer (PCR-SSP) DNA parting technology. RESULTS: A total of five specific loci were detected in the HLA-DQB1 locus among the Uygur and Han children. The frequency of the HLA-DQB1*02 allele in the Han group with severe caries (12.5%) was significantly lower than in the control group (32.5%) (P<0.05, OR=0.297). Moreover, the frequency of the HLA-DQB1*05 allele in the Uygur group with severe caries (37.5%) was significantly higher than in the control group (17.5%) (P<0.05, OR=2.829). CONCLUSIONS: Caries susceptibility among the Uygur and Han children in Xinjiang is related to the HLA-DQB1 allele. The HLA-DQB1*02 allele may protect against caries among the Han children, whereas the HLA-DQB1*05 allele may be responsible for the susceptibility of the Uygur children to caries.

PMID- 29594986 TI - Efficient Expression of an Alzheimer's Disease Vaccine Candidate in the Microalga Schizochytrium sp. Using the Algevir System. AB - Alzheimer's disease (AD) is the most common neurodegenerative disease, where beta amyloid (Abeta) plays a key role in forming conglomerated senile plaques. The receptor of advanced glycation end products (RAGE) is considered a therapeutic target since it transports Abeta into the central nervous system, favoring the pathology progression. Due to the lack of effective therapies for AD, several therapeutic approaches are under development, being vaccines considered a promising alternative. Herein, the use of the Algevir system was explored to produce in the Schizochytrium sp. microalga the LTB:RAGE vaccine candidate. Algevir relies in an inducible geminiviral vector and led to yields of up to 380 ug LTB:RAGE/g fresh weight biomass at 48-h post-induction. The Schizochytrium produced LTB:RAGE vaccine retained its antigenic activity and was highly stable up to temperatures of 60 degrees C. These data demonstrate the potential of Schizochytrium sp. as a platform for high production of thermostable recombinant antigens useful for vaccination against AD. PMID- 29594989 TI - [Influence of dexamethasone on the cell polarity and PAR complex of the embryonic epithelial cells in the palate]. AB - OBJECTIVE: This study aims to investigate whether dexamethasone (DEX) can down regulate the PAR complex and disrupt the cell polarity in the palatal epithelium during palatal fusion. METHODS: Pregnant rats were randomly divided into control and DEX groups, which were injected intraperitoneally with 0.9% sodium chloride (0.1 mL) and DEX (6 mg.kg -1), respectively, every day from E10 to E12. The palatal epithelial morphology was observed using hematoxylin and eosin staining and scanning electron microscopy. Immunofluorescence staining, Western Blot analysis, and real-time polymerase chain reaction were performed to detect the expression of PAR3, PAR6, and aPKC. RESULTS: The incidence of cleft palate in DEX group (46.15%) was significantly higher than that in control group (3.92%), and the difference was statistically significant (chi2=24.335, P=0.00). DEX can also retard the growth of the palatal shelves and the short palatal shelves. The morphology and arrangement of MEE cells changed from polarized bilayer cells to nonpolarized monolayer ones. Additionally, the spherical structure decreased, which caused the cleft palate. PAR3 and PAR6 were only detected in the palatal epithelium, and aPKC was expressed in the palatal epithelium and mesenchyme. DEX can reduce the expression levels of PAR3, PAR6, and aPKC in the protein and gene levels. CONCLUSIONS: DEX can down-regulate the complex gene expression in the MEE cells, thereby destroying the cell polarity and causing cleft palate. PMID- 29594990 TI - [Preparation and characterization of oriented scaffolds derived from cartilage extracellular matrix and silk fibroin]. AB - OBJECTIVE: This study aims to prepare oriented scaffolds derived from a cartilage extracellular matrix (CECM) and silk fibroin (SF) and use to investigate their physicochemical property in cartilage tissue engineering. METHODS: Oriented SF CECM scaffolds were prepared from 6% mixed slurry (CECM:SF=1:1) through modified temperature gradient-guided thermal-induced phase separation, followed by freeze drying. The SF-CECM scaffolds were evaluated by scanning electron microscopy (SEM) and histological staining analyses and determination of porosity, water absorption, and compressive elastic modulus of the materials. RESULTS: The SEM image showed that the SF-CECM scaffolds contained homogeneous reticular porous structures in the cross-section and vertical tubular structures in the longitudinal sections. Histological staining showed that cells were completely removed, and the hybrid scaffolds retained proteogly can and collagen. The composition of the scaffold was similar to that of natural cartilage. The porosity, water absorption rate, and vertical compressive elastic modulus of the scaffolds were 95.733%+/-1.010%, 94.309%+/-1.302%, and (65.40+/-4.09) kPa, respectively. CONCLUSIONS: The fabricated SF-CECM scaffolds exhibit satisfactory physicochemical and biomechanical properties and thus could be an ideal scaffold in cartilage tissue engineering. PMID- 29594991 TI - [Neurotrophin 3 promotes osteogenic differentiation of human dental follicle cells]. AB - OBJECTIVE: This study aims to investigate the effect of neurotrophin 3 (NT-3) on the osteogenic differentiation of human dental follicle cells (hDFCs). METHODS: hDFCs were isolated and cultured in vitro. Immunocytochemical staining was used to identify the origin of hDFCs. The effects of different NT-3 concentrations on hDFCs proliferation were detected by using CCK-8 assay. The alkaline phosphatase (ALP) activities and mRNA expression levels of bone morphogenetic protein-2 (BMP 2) and osteocalcin (OCN) were determined to investigate the effects of NT-3 on hDFCs osteogenesis. The difference in the number of mineralized nodules was detected using alizarin red staining. RESULTS: Vimentin and cytokeratin staining results showed that hDFCs originated from the mesenchymal cells. NT-3 exerted no evident effect on hDFCs proliferation. The ALP activity and the BMP-2 and OCN mRNA expression levels of hDFCs were significantly improved under treatment with different NT-3 concentrations (25, 50, and 100 ng.mL -1) compared with those in the control group. BMP-2 and OCN mRNA relative expression levels of hDFCs reached the highest when the NT-3 concentration was 100 ng.mL -1. The number of mineralized nodules reached the maximum when the hDFCs were treated with 50 and 100 ng.mL -1 NT-3. CONCLUSIONS: Appropriate mass concentration of NT-3 can promote the osteogenic differentiation of hDFCs. PMID- 29594992 TI - [Expression and clinical significance of proline-rich tyrosine kinase 2 and phospho-protein kinase B in tongue squamous cell carcinoma]. AB - OBJECTIVE: This study aimed to investigate the expression and clinical significance of proline-rich tyrosine kinase 2 (Pyk2) and phospho-protein kinase B (p-AKT) in tongue squamous cell carcinoma (TSCC) and adjacent nontumor tissues. METHODS: The Pyk2 and p-AKT protein levels were detected via immunohistochemistry in 45 cases of TSCC tissues and 30 cases of adjacent nontumor tissues. The relationships of the two protein levels and clinicopathological characteristics were also analyzed. RESULTS: Pyk2 and p-AKT levels were significantly higher in the TSCC tissues than in the adjacent nontumor tissues (P<0.05). Nontumor tissues showed poor or no expression. The expression levels of the two proteins were positively correlated (gammas=0.412). The expression of Pyk2 was associated with histopathological differentiation type, regional lymph node metastasis, and TNM staging (P<0.05), but not with age and gender. The expression of p-AKT was only related to histopathological differentiation types (P<0.05). CONCLUSIONS: The abnormal expression of Pyk2 and p-AKT proteins might be closely related to the development and progression of TSCC. Joint detection can be used as an indicator to estimate the degree of TSCC. PMID- 29594993 TI - [Experimental study of demineralized dentin matrix on osteoinduction and related cells identification]. AB - OBJECTIVE: The aim of this study was to explore the theoretical framework of cells and the forms of osteogenesis in the mechanism by which demineralized dentin matrix (DDM) induces osteogenesis. METHODS: A total of 24 New Zealand rabbits were used in this study. A total of 4 erector spinae bags were created in each animal. A total of 3 erector spinae bags were implanted with DDM by random selection, whereas the remaining one erector spinae bag was not implanted with DDM. The rabbits were sacrificed after 1, 2, 3, 4, 8, 12, 16, and 20 weeks, and the samples were obtained. The samples were examined by hematoxylin-eosin (HE), tartrate-resistant acid phosphatase (TRAP), and immunohistochemical staining to identify the mesenchymal stem cells, osteoblasts, chondrocytes, and osteoclasts. RESULTS: The results of HE staining showed that in the third week, cartilage- and bone-like matrices, as well as the osteoblast-like cells, were observed. The results of immunohistochemical staining showed that the expressions of CD44, alkaline phosphatase (ALP), and collagen II were statistically significant ?(P<0.05). CONCLUSIONS: DDM has good histocompatibility and osteoinduction. In addition, induced ectopic osteogenesis mode mainly occurs in the endochondral bone. PMID- 29594994 TI - [K (lysine) acetyltransferase 2A affects the osteogenic differentiation of periodontal ligament stem cells through the canonical Wnt pathway]. AB - OBJECTIVE: This study aims to investigate the mechanism of K (lysine) acetyltransferase 2A (KAT2A) regulation and control on the osteogenic differentiation of periodontal ligament stem cells (PDLSCs). METHODS: The expression levels of KAT2A in PDLSCs were compared from each generation of the normal (H-PDLSCs) and periodontitis tissues (P-PDLSCs). The influences of KAT2A gene interference on the osteogenic differentiation of PDLSCs were also detected. In addition, the influences of the KAT2A gene interference to the canonical Wnt pathway and ligands were detected. The upstream and down-stream relationships between KAT2A and canonical Wnt pathway were also determined. RESULTS: The decreased expression of KAT2A in PDLSCs from the inflammatory tissue in each generation was compared with that in PDLSCs from the healthy tissue, and the difference was statistically significant (P<0.05). When the KAT2A gene was disrupted, the osteogenesis ability of PDLSC was declined, and the difference was statistically significant (P<0.05). The canonical Wnt pathway was activated, and the antagonist Dickkopf-1 (DKK-1) was reduced. After the DKK-1 addition, the osteogenic differentiation of the disturbed PDLSCs was recovered, and KAT2A was unaffected. CONCLUSIONS: The KAT2A expression in PDLSCs was decreased because of perio-dontitis. The classical Wnt pathway was activated to inhibit the osteogenic differentiation of the cells.

AB - OBJECTIVE: This investigation aimed to develop a novel antibacterial dental adhesive containing nanoantibacterial inorganic fillers and measure the dentin bonding strength, mechanical properties, and antibacterial property of the novel adhesive in vitro. METHODS: Novel nanoantibacterial inorganic fillers containing quaternary ammonium salt with long chain alkyl were synthesized on the basis of previous research. These novel nanoantibacterial inorganic fillers were added into the dental adhesive to prepare novel nanoantibacterial dental resin composite at mass fractions of 0%, 2.5%, 5.0%, 7.5%, and 10%; 0% was used as control. Dentin shear bonding test was used to evaluate the bonding strength. Flexural test was utilized to measure the novel resin composite flexural strength and elastic modulus. A dental plaque microcosm biofilm model with human saliva as inoculum was formed. Colony forming unit, lactic acid production, and live/dead assay of the biofilm on novel dental adhesive were calculated to assess the effect of novel dental adhesive on human dental plaque microcosm biofilm. RESULTS: The dentin shear bond strength, flexural strength, and elastic modulus were 28.9 MPa, 86.6 MPa, and 4.2 GPa, respectively, when the nanoantibacterial inorganic filler mass fraction in the dental adhesive reached approximately 5.0%. Consequently, the dentin shear bond strength and mechanical properties significantly increased. Addition of 2.5% nanoantibacterial inorganic fillers into the dental adhesive exerted no adverse effect on the mechanical properties significantly (P>0.05). Dental adhesive containing 5% or more nanoantibacterial inorganic fillers inhibited the metabolic activity of the dental plaque microcosm biofilm significantly, thereby displaying a strong antibacterial potency (P<0.05). CONCLUSIONS: This novel antibacterial dental adhesive, which contained 5.0% nanoantibacterial inorganic filler, exhibited promising bonding strength, mechanical property, and antibacterial ability. Hence, this adhesive can be potentially used in caries inhibition in dental application.

AB - OBJECTIVE: This study aims to explore the effect of cosmetic technique on the modification of lip deformity after cleft lip surgery. METHODS: A total of 35 patients with postoperative cleft lip and who needed two-stage repair due to the nasolabial deformity were selected. Cosmetic technique was used to modify their lip deformities prior to the surgery. Front photos of the patients were taken before and after modification of their lip deformities. These photos were subsequently assessed by both the patients and the medical staff. The visual analogue method, Asher-McDade aesthetic index, and Mortier PB scale were used by patients and medical staff to evaluate changes in the lip shape by the cosmetic technique. RESULTS: Prior to the cosmetic technique application, the mean self score of the patients and the mean scores of the medical staff were 56+/-13 and 3.22+/-1.11 points, respectively. After the cosmetic technique application, the mean self-score of the patients and the mean scores of the medical staff were 67+/-12 and 2.85+/-1.03 points, respectively. The differences were statistically significant for both the patients and the medical staff (P<0.05). CONCLUSIONS: Appropriate use of the cosmetic technique can modify the lip deformity after the cleft lip surgery to a certain degree. The use of this technique exerts evident effects in restoring the symmetry?of lip peak and the continuity of the labial arch and in highlighting the philtrum column.

AB - OBJECTIVE: This study aims to evaluate the reliability of the software Picpick in the measurement of the cusp inclination angle of a digital model. METHODS: Twenty one trimmed models were used as experimental objects. The chairside digital impression was then used for the acquisition of 3D digital models, and the software Picpick was employed for the measurement of the cusp inclination of these models. The measurements were repeated three times, and the results were compared with a gold standard, which was a manually measured experimental model cusp angle. The intraclass correlation coefficient (ICC) was calculated. RESULTS: The paired t test value of the two measurement methods was 0.91. The ICCs between the two measurement methods and three repeated measurements were greater than 0.9. The digital model achieved a smaller coefficient of variation (9.9%). CONCLUSIONS: The software Picpick is reliable in measuring the cusp inclination of a digital model.

AB - OBJECTIVE: This study aimed to investigate the application of an osteotomy template and a repositioning template manufactured by three-dimensional (3D) printing technique in maxillary LeFortIosteotomy. METHODS: The patient group consisted of eight patients with maxillary hypoplasia who underwent LeFortIosteotomy. The mean age at the time of surgery was 25.6 years old. All patients were scanned using cone beam computed tomography (CBCT) to create a 3D model of the maxillary. The osteotomy and repositioning templates of the LeFortIosteotomy were manufactured by 3D printing technique. All bones were cut by the same doctor with extensive orthognathic surgery experience. One part of the template guided the osteotomy, and the other repositioned the maxilla during operation. Postoperative CBCT scan was performed, and the virtual plan was compared with the postoperative surgical result using an image fusion of the CBCT dataset by analyzing measurements between six landmarks relative to three reference planes. Statistical analysis was performed, and accuracy was reported using SPSS 16.0 software package. RESULTS: Primary healing of incisions was observed in all patients, and no serious complications were observed. The maximum mean values were 1.35 mm, and the displacement error was UL6 to the coronal plane. The maximum standard deviation was 0.85, and the maximum standard error was 0.30, which was acceptable by clinical standards. CONCLUSIONS: The application of osteotomy and repositioning templates manufactured by 3D printing technique in maxillary LeFortIosteotomy was safe and can enable doctors to complete a surgery accurately.

AB - OBJECTIVE: This study aimed to compare the effect of D55 and D65 light sources on the visual colorimetry performance of dental students by using a homemade light source shelf. METHODS: Two Vitapan 3D-Master shade guides were randomly selected. One set was used as shade guides. Ten commonly used shade tabs of 2L2.5, 2M2, 2R2.5, 3M2, 3R2.5, 3L1.5, 3R1.5, 3L2.5, 4R1.5, and 4L1.5 were selected from the other set with covered value marks and numbered from 1 to 10. After the colorimetric training, 49 undergraduate dental students were randomly divided into two groups. Each student randomly selected two of the 10 shade tabs, and the colors were subsequently matched under D65 and D55 light sources from a distance of approximately 40 cm. The average color difference (DeltaE) between the color selected by each participant and the actual color of shade tabs was calculated. Paired t test was used for statistical analysis. RESULTS: The DeltaE values between the color selected by each participant and the actual color of the shade tabs under the D55 light source varied from 0 to 6.540. The average value was 2.501. The DeltaE values between the color selected by each participant and the actual color of the shade tabs under the D65 light source varied from 0 to 6.610. The average value was 2.530. No statistically significant difference was observed between the results under the two light sources (P=0.921). CONCLUSIONS: Both D55 and D65 daylight lamps can be used for daily dental colorimetry. These two different color temperatures showed no significant difference. PMID- 29595000 TI - [Application of periodontal microsurgery in the augmentation of attached gingiva around an implant]. AB - OBJECTIVE: This study aimed to evaluate the clinical effect of periodontal microscopic surgery on the augmentation of attached gingiva and determined the clinical principle on how to use minimally invasive surgery to improve the surgery success rate. METHODS: Twenty patients with insufficient attached gingiva around implants were selected. Periodontal microscopic surgery for free gingival graft was performed to increase the width of the attached gingiva around the implants. The survival state of the free gingiva was observed after surgery, and the width of the attached gingiva around the implants was recorded before and after surgery and 1 year after surgery. The shrinkage rate of the free gingival flap 1 year after surgery was analyzed to evaluate the stability of the flap. RESULTS: The flaps of the 20 cases all survived. One year after the operation, the width of the attached gingiva was (3.05+/-0.44) mm, which increased compared with that of preoperation (2.56+/-0.31) mm?and decreased compared with that of postoperative day (2.13+/-0.28) mm. The shrinkage rate of the attached gingiva was 41.22%+/-5.04%. CONCLUSIONS: The application of microscopic surgery on the augmentation surgery of attached gingiva can increase the success rate and improve the quality and quantity of attached gingiva around implants.

AB - OBJECTIVE: This study aims to use Arginine-gingipain A gene vaccine (pVAX1-rgpA) to immunize adult Beagle dogs and to evaluate its effect during peri-implantitis progression and development. METHODS: Plasmid pVAX1-rgpA was constructed. The second and third bilateral mandible premolars of 15 adult Beagle dogs were extracted, and the implants were placed immediately. After 3 months, the animals were randomly divided into groups A, B, and C. Afterward, the animals were immunized thrice with plasmid pVAX1-rgpA, with heat-killed Porphyromonas gingivalis, or pVAX1, respectively. IgG in the serum and secretory IgA (sIgA) in saliva were quantitatively analyzed by enzyme-linked immunosorbent assay before and after 2 weeks of immunization. Peri-implantitis was induced with cotton ligatures fixed around the neck of implants. Probing depth (PD) and bleeding on probing were recorded. All animals were sacrificed after ligaturation for 6 weeks. Decalcified sections with thickness of 50 MUm were prepared and dyed with methylene blue to observe the bone phenotype around implants. RESULTS: Levels of serum IgG and sIgA in saliva were higher in groups A and B after immunization than before the process (P<0.05) and higher than those in group C (P<0.05). However, no difference was observed between groups A and B (P>0.05). At 4 and 6 weeks after ligaturation, PD of the ligatured side in group C was higher than that in groups A and B (P<0.05). On the other hand, no difference was identified between groups A and B (P>0.05). Bone loss in group A was significantly lower than that of the other groups (P<0.05). Abundant inflammatory cells and bacteria were present in the bone loss area around the implants in the three groups, as identified through hard tissue section observation. However, group C presented the most number of inflammatory cells and bacteria in the bone loss area around the implants. CONCLUSIONS: IgG and sIgA can be generated by immunity with rgpA DNA vaccine, which can significantly slow down bone loss during experimental peri implantitis in dogs. PMID- 29595002 TI - [Disheveled 2 around the implant at an early stage of hyperlipidemic rats]. AB - OBJECTIVE: This study aims to investigate the expression of disheveled 2 (Dvl2) around the implant of hyperlipidemic rats at an early stage after the implantation. METHODS: A total of 24 Wistar rats were divided equally into the experimental group fed with high-fat diet group and control group fed with a normal diet. After 8 weeks, the serum lipid levels were detected, and rats received implants in the femur metaphysis. Rats were sacrificed at 1, 3, and 5 days after implantation, and the bones around implants were obtained. Methylene blue-acid fuchsin staining was performed to observe the implant-bone interface. Real-time polymerase chain reaction was performed on runt-related transcription factor 2 (Runx2), cathepsin K (CatK), and Dvl2. Dvl2 Western blot or immunoprecipitation, phosphorylation, and ubiquitination were also conducted. RESULTS: In the experimental group, less osteoblasts, lower expression of Runx2 and Dvl2, and lower Dvl2 phosphorylation (P<0.05) than those of the control group were observed; furthermore, the CatK expression and Dvl2 ubiquitination were higher than those in the control group (P<0.05). CONCLUSIONS: Hyperlipidemia may suppress bone remodeling around the implant at an early stage by Dvl2 down regulation, phosphorylation, and up-regulated ubiquitination.

AB - Aesthetic and comfortable transparent retainers and clear plastic appliances are becoming increasingly popular, and their components, especially thermoplastic materials, are gradually attracting widespread interest. Orthodontic thermoplastic materials are versatile polymers, and thus their properties, such as force delivery, force relaxation, and aging properties have been comprehensively studied. Meanwhile, blending modification technology has been applied for the acquisition of novel materials with enhanced characteristics. In this paper, we review the types and properties of thermoplastic materials, the development process they undergo, factors that influence their properties, and some development prospects. PMID- 29595004 TI - [Mechanisms and implications of cancer cell dormancy in head and neck carcinoma]. AB - Disease metastasis and relapse in many cancer patients several years (even decades) after surgical remission have been recently acknowledged as cases of cancer dormancy. Although cases of minimal residual disease are well documented, knowledge on its biological mechanisms and clinical implications remains limited. To date, numerous reviews have summarized the three potential models that may explain this phenomenon, including the angiogenic, immunologic, and cellular dormancy. In this study, we discuss newly uncovered mechanisms governing tumor cell dormancy in head and neck cancer, emphasizing on the crosstalk between dormant tumor cells and their microenvironments. Additionally, we explore the mechanisms on the reactivation of dormant residual tumor cells in anatomical sites, including the lymph nodes and bone marrow.

Chronic low-grade inflammation accompanied by sustained stimuli is correlated with various age-related diseases (ARDs). Recent studies on ARDs have prompted further research interest in the inner mechanisms underlying inflammaging to establish prevention and treatment plans for inflammatory diseases. In this article, we discuss inflammaging and its significant role in periodontitis. PMID- 29595006 TI - [Recent achievements in the microbiological etiology of dental caries]. AB - Dental caries is the most common chronic infectious disease of the oral cavity. The bacterium Streptococcus mutans is the sole pathogen that causes this disease. However, substantial evidence suggests that prevention and treatment strategies developed from traditional "cariogenic pathogen theory" are inefficient in reducing the prevalence of dental caries. An increasing number of individuals adopt the ecological view of the microbiota in the pathogenesis of dental caries. Recent technological improvements have enabled the detection and analysis of oral microorganisms, and many studies have focused on this area. The core microbiota is defined as a cluster of microbes playing critical roles in the initial and development phases of dental caries and may provide future direction for microorganism-related etiological studies. PMID- 29595007 TI - [Treatment of a patient with considerably thin alveolar bone and severe open bite]. AB - This case report describes the treatment of a 25-year-old woman with a severe open bite. This patient presented a grade III open bite, considerably thin alveolar bone, and evident labial buccal and lingual root form. The open bite was corrected by fixed orthodontic treatment and masticatory exercises. However, the increased pressure in the labial muscle caused by lip muscle exercise suppressed the canines, which resulted in the protrusion of the apices of canine roots out of the alveolar bone. Afterward, HX brackets, instead of self-locking, were used and bonded reversely in the occlusal-gingival direction on the upper canines. The lip muscle exercises were decreased. After adjustment, the roots penetrated back into the cancellous bone, the severe open bite was corrected, and a normal overbite and overjet were achieved. ClassIcanine and molar relationships were established. The masticatory function and profile were both considerably improved. This case report showed that a severe nonskeletal open bite can be corrected using orthodontic treatments combined with masticatory exercises.

The Belgian Health Care Knowledge Centre (KCE) has been surrounded by 31 clinicians from different disciplines to develop a guideline covering the entire management of low back and radicular pain. A recently published guideline of the British National Institute for Health and Care Excellence (NICE) was largely used as a starting point and adapted to the Belgian context. PMID- 29595010 TI - [Asthma and obesity : preventable therapeutic trap, with careful follow-up]. AB - Nowadays, more and more obese asthmatics visit a pulmonologist. It is proven that overweight stirs up the severity of the bronchopathy. It is a concept that is now anchored in the minds of most modern practitioners. Nevertheless, the idea that in some patients, excess weight can be an independent cause of the persistence of respiratory complaints, is sometimes neglected. This case report is about a severely obese poorly controlled asthmatic man, who turns out to be suffering from a concomitant obesity-hypoventilation syndrome. His clinical history confirms the necessity of quickly detecting this restrictive syndrome within an obstructive background, before its evolution towards a severe acute respiratory failure, where therapeutic approximations can have dramatic repercussions on the patient's health. PMID- 29595011 TI - [Incidental findings of maternal genetic abnormalities during non-invasive prenatal screening]. AB - The non-invasive prenatal test (NIPT) has recently been added in our clinical practice. Sensitivity and specificity of this method in the common fetal aneuploidies screening is about 99 %. This technique remains a screening test, not a diagnosis test, because false positive or negative results exist. The discordant results are explained by the method itself witch analyses the whole free circulating DNA in the maternal blood: the fetal DNA from trophoblastic cells lysing but also the maternal DNA. Placenta confined mosaic is the main false positive cause reported in the literature. NIPT can rarely reveal maternal abnormalities. We are reporting two cases carrying a cytogenetic anomaly revealed with NIPT: microduplication of 22q11.2 and a sexual chromosomes anomaly. PMID- 29595012 TI - [Lyme disease or not ?] AB - Lyme disease is a complex pathology due to an infection by a spirochaete from the genus Borrelia. This infection results from a tick bite lasting more than 24 hours. Signs and symptoms are numerous and are usually classified in three stages: early localized disease, early disseminated disease and late disease. The skin, the heart, the nervous system and the joints are mostly concerned. It is important to distinguish the clinical manifestations of the disease from those that are sometimes associated with it but with no scientific evidence. The purpose of this article is to insist on which signs and symptoms can be related to the disease and on those that usually are not. Diagnostic methods and treatments are also discussed. PMID- 29595013 TI - [Multidisciplinary management of alveolar echinococcosis : Echino-Liege Working Group]. AB - Alveolar echinococcosis is a zoonotic disease due to the tapeworm Echinococcus multilocularis. The definitive host is the red fox. Until recently, Belgium was considered a country at very low risk for alveolar echinococcosis. However, recent studies carried out in southern Belgium have revealed, through post-mortem examination, high prevalences (up to 62 %) in foxes. Cats and dogs can act as definitive hosts. Human are accidentally infected by ingestion of food contaminated by the feces. After a long incubation period, invasive hepatic lesions may appear, as well as extra-hepatic lesions. The disease may be fatal. The diagnosis is based on imaging techniques, serology and nucleic acid detection in tissues. Early diagnosis may allow surgical removal of the lesion associated with at least 2 years of albendazole postoperative treatment. In case of contraindication to surgery, a long term treatment with albendazole is necessary. Liver transplantation is sometimes necessary. This article presents the epidemiologic, clinical, diagnostic and therapeutics features of this zoonotic disease. PMID- 29595014 TI - [Invasive diagnostic techniques for diffuse interstitial pneumopathies]. AB - Interstitial lung diseases represent a very heterogeneous group of diseases mainly affecting connective lung tissue even if alveolar space may sometimes be involved. The identification of their etiology is the key stage in their management. It requires the integration of anamnestic, clinical, biological, radiological data and, sometimes relies on, cytology or histology. In this review, we assess the contribution and feasibility of the different invasive techniques used for interstitial lung disease diagnosis. In particular we focus on the yield of lung endoscopy in casting light on the multidisciplinary confrontation, which is the gold standard of the interstitial lung disease care management.

PMID- 29595016 TI - High-sensitivity terahertz imaging of traumatic brain injury in a rat model. AB - We demonstrated that different degrees of experimental traumatic brain injury (TBI) can be differentiated clearly in fresh slices of rat brain tissues using transmission-type terahertz (THz) imaging system. The high absorption region in THz images corresponded well with the injured area in visible images and magnetic resonance imaging results. The THz image and absorption characteristics of dehydrated paraffin-embedded brain slices and the hematoxylin and eosin (H&E) stained microscopic images were investigated to account for the intrinsic differences in the THz images for the brain tissues suffered from different degrees of TBI and normal tissue aside from water. The THz absorption coefficients of rat brain tissues showed an increase in the aggravation of brain damage, particularly in the high-frequency range, whereas the cell density decreased as the order of mild, moderate, and severe TBI tissues compared with the normal tissue. Our results indicated that the different degrees of TBI were distinguishable owing to the different water contents and probable hematoma components distribution rather than intrinsic cell intensity. These promising results suggest that THz imaging has great potential as an alternative method for the fast diagnosis of TBI. PMID- 29595017 TI - Spectral refractive index assessment of turbid samples by combining spatial frequency near-infrared spectroscopy with Kramers-Kronig analysis. AB - A practical algorithm for estimating the wavelength-dependent refractive index (RI) of a turbid sample in the spatial frequency domain with the aid of Kramers Kronig (KK) relations is presented. In it, phase-shifted sinusoidal patterns (structured illumination) are serially projected at a high spatial frequency onto the sample surface (mouse scalp) at different near-infrared wavelengths while a camera mounted normally to the sample surface captures the reflected diffuse light. In the offline analysis pipeline, recorded images at each wavelength are converted to spatial absorption maps by logarithmic function, and once the absorption coefficient information is obtained, the imaginary part (k) of the complex RI (CRI), based on Maxell's equations, can be calculated. Using the data represented by k, the real part of the CRI (n) is then resolved by KK analysis. The wavelength dependence of n ( lambda ) is then fitted separately using four standard dispersion models: Cornu, Cauchy, Conrady, and Sellmeier. In addition, three-dimensional surface-profile distribution of n is provided based on phase profilometry principles and a phase-unwrapping-based phase-derivative variance algorithm. Experimental results demonstrate the capability of the proposed idea for sample's determination of a biological sample's RI value. PMID- 29595018 TI - Speckle attenuation by adaptive singular value shrinking with generalized likelihood matching in optical coherence tomography. AB - As a high-resolution imaging mode of biological tissues and materials, optical coherence tomography (OCT) is widely used in medical diagnosis and analysis. However, OCT images are often degraded by annoying speckle noise inherent in its imaging process. Employing the bilateral sparse representation an adaptive singular value shrinking method is proposed for its highly sparse approximation of image data. Adopting the generalized likelihood ratio as similarity criterion for block matching and an adaptive feature-oriented backward projection strategy, the proposed algorithm can restore better underlying layered structures and details of the OCT image with effective speckle attenuation. The experimental results demonstrate that the proposed algorithm achieves a state-of-the-art despeckling performance in terms of both quantitative measurement and visual interpretation.

AB - Nicotinamide has been shown to affect blood flow in both tumor and normal tissues, including skeletal muscle. Intraperitoneal injection of nicotinamide was used as a simple intervention to test the sensitivity of noninvasive diffuse correlation spectroscopy (DCS) to changes in blood flow in the murine left quadriceps femoris skeletal muscle. DCS was then compared with the gold-standard fluorescent microsphere (FM) technique for validation. The nicotinamide dose response experiment showed that relative blood flow measured by DCS increased following treatment with 500- and 1000-mg / kg nicotinamide. The DCS and FM technique comparison showed that blood flow index measured by DCS was correlated with FM counts quantified by image analysis. The results of this study show that DCS is sensitive to nicotinamide-induced blood flow elevation in the murine left quadriceps femoris. Additionally, the results of the comparison were consistent with similar studies in higher-order animal models, suggesting that mouse models can be effectively employed to investigate the utility of DCS for various blood flow measurement applications. PMID- 29595022 TI - Culture Clash: Shona (Zimbabwean) Migrant Women's Experiences with Communicating about Sexual Health and Wellbeing across Cultures and Generations. AB - This paper discusses the influence of cross-cultural modes of communication on perceptions of sexual health and wellbeing for Shona (Zimbabwean) women living in Australia and their children. Data was collected using focus groups in South Australia with fourteen women, between the ages of 29 and 53. Transcripts were analysed thematically. The women primarily constructed sexual health and wellbeing in customary Shona ways, which not only maintain secrecy about sexual health and wellbeing discourse, but also prohibit parents from talking to children about sexual health as such talk is reserved for particular kin and non kin relationships. These constructions however became more fluid the longer the women resided in Australia. For these women the notions of sexual health and wellbeing are a negotiation between Australian constructs and those from Shona culture, especially when applied to their children. This research highlights the potential influence of various cultural world views on sexual health communication among African migrant women and their children and questions the appropriateness of sexual health and wellbeing campaigns and their responsiveness for cross-cultural youth. PMID- 29595023 TI - Cost-Effectiveness Analysis of Family Planning Services Offered by Mobile Clinics versus Static Clinics in Assiut, Egypt. AB - Cost effectiveness studies of family planning (FP) services are very valuable in providing evidence-based data for decision makers in Egypt. Cost data came from record reviews for all 15 mobile clinics and a matched set of 15 static clinics and interviews with staff members of the selected clinics at Assiut Governorate. Effectiveness measures included couple years of protection (CYPs) and FP visits. Incremental cost-effectiveness ratios (ICER) and sensitivity analyses were calculated. Mobile clinics cost more per facility, produced more CYPs but had fewer FP visits. Sensitivity analysis was done using: total costs, CYP and FP visits of mobile and static clinics and showed that variations in CYP of mobile and static clinics altered the ICER for CYP from $2 -$6. Mobile clinics with their high emphasis on IUDs offer a reasonable cost effectiveness of $4.46 per additional CYP compared to static clinics. The ability of mobile clinics to reach more vulnerable women and to offer more long acting methods might affect a policy decision between these options. Static clinics should consider whether emphasizing IUDs may make their services more cost-effective.

AB - Maternal and Child Health Integrated Program (MCHIP), a program by Jhpiego global, implemented maternal and newborn health project between 2006 and 2010 in Kano and Zamfara States, Nigeria. This was evaluated with an objective to characterize the effects of volunteer household counselors (VHCs) upon improving knowledge of birth preparedness and complication readiness (BPCR) among pregnant women. VHCs were trained to educate women and their families at home about BPCR. Knowledge of BPCR was compared among 152 and 594 women who did and did not receive household counseling. Mothers' knowledge of BPCR among those who did and did not receive counseling was 32.2% and 11.2% respectively. Mothers who received counseling had better knowledge of BPCR compared to women who did not (Relative Risk [R.R.] 2.30, 95% [C.I.] 1.50, 3.51, P = 0.0001) in a multivariable logistic regression model adjusting for potential confounders. Mothers who received counseling had better odds of knowledge of danger signs during delivery (R.R. 1.48, 95% C.I. 1.05, 2.09, P = 0.02), and post-partum period (R.R. 1.69, 95% C.I. 1.22, 2.32, P = 0.001), but not during pregnancy (R.R. 1.26, 95% C.I. 0.97, 1.64, P = 0.08), compared with women who received no counseling. VHCs can substantially increase knowledge of BPCR and danger signs among women in Nigeria. PMID- 29595025 TI - Contraceptives: Adolescents' Knowledge, Attitudes and Practices. A Case Study of Rural Mhondoro-Ngezi District, Zimbabwe. AB - Adolescent reproductive health behaviour has become an emerging world concern as the age at menarche and sexual debut has plummeted globally. The primary objective of the paper is to understand the importance of reproductive health education to contraceptive use among adolescents in Mhondoro-Ngezi District. The paper also investigates knowledge, attitudes, beliefs and practices (KABP) pertaining to contraceptive use among adolescents. Factors underlying KABP are further explored. In addition, this paper investigates the availability, accessibility, acceptability and affordability of contraceptives to adolescents. These issues are assessed from the perspective of all duty bearers (mothers, fathers, healthcare providers, religious leaders and secondary school teachers). The paper is based on a cross-sectional study which was conducted in Mhondoro Ngezi area. A total of 185 adolescents aged 15-19 years were sampled with a sex ratio of 67. The study triangulated both quantitative and qualitative methods of data collection. The results in this paper indicate that adolescents in Mhondoro Ngezi engage in early sexual debut. Despite the fact that knowledge about modern contraceptives is universal (96%) among adolescents in Mhondoro-Ngezi, contraceptive use is very low, 21%. Limited contraceptive use among adolescents in the study area is a result of the interplay of demographic, policy, socio cultural, religious and economic factors. The study has thus recommends that the government and other relevant stakeholders to formulate policies that promote reproductive education in order to foster the utilization of contraceptives by adolescents. PMID- 29595026 TI - Dual Protection and Contraceptive Method Use among Women in Heterosexual Relationships in Mahikeng, South Africa. AB - South African new reproductive health policies have given weight to dual protection as a public health intervention against unintended pregnancies and sexually transmitted infections. However, studies of dual protection have remained scanty and under researched in South Africa. This situation has left the reproductive health policy makers clueless about salient strategies to promote dual contraceptive method use. A survey of 568 women in steady relationships aged 15-49 was conducted in Mahikeng Municipality. Using multivariate logistic regression independent predictors of contraceptive method use were examined and presented as odds ratio and 95% confidence intervals. Sixteen percent of the women were currently protecting against both unintended pregnancies and infectious diseases while 40% were protecting against unintended pregnancies only. Age, occupation, ever discussed condom use with partner; home language and religion were the independent predictors of dual method use. Non-barrier method use was associated with age, home language, religion, and duration of union. The study concludes that educative and enlightening programs that emphasize women's employment and communication about condom use may be specifically helpful in promoting dual method use.

AB - Multiple sexual partnerships (MSP) have been identified as the main reason for the high rate of HIV prevalence in sub-Saharan Africa, including Lesotho. The aim of this paper is to identify the social and economic variables associated with MSP among men in Lesotho. The study used data from 2009 Lesotho Demographic and Health Survey. A sample of 2335 males in the age group 15-44 was used. Participants qualified if they were sexually active during the past year before the survey. Binary logistic regression was used to analyse the data. Results indicated that 29% of the respondents had engaged in sexual intercourse with multiple partners in the past year. Lower age at sexual debut, employment; having ever moved from home in the past year; believing that men have the right to have sex with other women; believing that beating a woman is justified if she argues with husband and having sex with casual partner were associated with an increased likelihood of MSP. On the other hand, coming from household led by a woman reduced the odds ratio. The study recommends that promotion of awareness programmes on MSP coupled with economic empowerment of women should be intensified in Lesotho.

AB - Penal code was revised in Rwanda in 2012 allowing legal termination of pregnancy resulting from rape, incest, forced marriage, or on medical grounds. An evaluation was conducted to assess women's access to abortion services as part of an ongoing program to operationalize the new exemptions for legal abortion. Data was collected from eight district hospitals; seven gender-based violence (GBV) centers and six intermediate courts. Three focus group discussions and 22 in depth interviews were conducted with key informants. At hospitals, of the 2,644 uterine evacuation records (July 2012-June 2014), and 312 monitoring cases (August-December 2014), majority of all uterine evacuations (97% and 85% respectively, for the two periods) were for obstetric conditions, and induced abortion on medical grounds accounted for 2% vs. 15% respectively. Medical abortion was the prominent method of uterine evacuation. At the GBV centers, 3,763 records were identified retrospectively; 273 women were pregnant. Since the legal reform there was only one abortion for a pregnancy resulting from rape. Abortion stigma and court order requirement are major barriers to access services. The operationalization program has made significant contributions to make abortion safer in Rwanda but this evaluation demonstrates that further work is required to reach the goal of providing safe abortion services to all eligible women. Addressing abortion stigma at the community, organizational and structural levels; further strengthening of service provision; and streamlining legal requirements to protect particularly young women from sexual violence and making abortion a realistic option for GBV victims are some of the important next steps.

AB - This article presents the results of the literature review performed on the main conceptual models used in the measurement of the satisfaction of women during childbirth in health facilities and the main determinants of their satisfaction. The review focused on PubMed, Google scholar and Public Health data. Several conceptual models for measuring satisfaction were found through the literature. It is clear from this review that a multitude of determinants are associated with women's satisfaction such as health care provider's attitude, the environment as well as the socio-demographic, economic and even psychological characteristics of the patient herself. These results were used to develop a conceptual framework for measuring the satisfaction of women who gave birth in Senegal health facilities. PMID- 29595030 TI - The Effectiveness of a Collector Bag for Measurement of Post-partum Hemorrhage. AB - The aim of the study was to assess sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) of collector bag and its correlation with hemoglobin (Hb) and hematocrit (Ht) variations. This study, carried on 100 women referred for admission to labor ward of Shohada hospital in Orumeyeh City, Iran, from April to November, 2007. Serum Hb and Ht were measured after admission; a collecting bag placed under the pelvis just after birth and was weighted after delivery. Hb and Ht were again assessed at 8 hr after delivery. PPH was defined as blood loss ?500 ml following vaginal delivery. Each 500 ml blood loss accounts for approximately a 3% change in the Ht level or a falling in Hb of 1 g/dl. With this cut off our noted Sensitivity=80%, Specificity=95. 7%, PPV= 88.9% and NPV= 91.8%. The collector bag is a rapid and precise instrument to diagnose of postpartum hemorrhage in the delivery room. It also enables a visual, quantitative and objective estimation of blood loss.

AB - The objective of this study was to document maternal and child health care workers' knowledge, attitudes and practices on service delivery before, during and after the 2014 EVD outbreak in rural Guinea. We conducted a descriptive cross sectional study in ten health districts between October and December 2015, using a standardized self-administered questionnaire. Overall 299 CHWs (94% response rate) participated in the study, including nurses/health technicians (49%), midwives (23%), managers (16%) and physicians (12%). Prior to the EVD outbreak, 87% of CHWs directly engaged in managing febrile cases within the facility, while the majority (89% and 63%) referred such cases to another facility and/or EVD treatment centre during and after the EVD outbreak, respectively. Compared to the period before the EVD outbreak when approximately half of CHWs (49%) reported systematically measuring body temperature prior to providing any care to patients, most CHWs reported doing so during (98%) and after the EVD outbreak (88%). The main challenges encountered were the lack of capacity to screen for EVD cases within the facility (39%) and the lack of relevant equipment (10%). The majority (91%) of HCWs reported a decrease in the use of services during the EVD outbreak while an increase was reported by 72% of respondents in the period following the EVD outbreak. Infection prevention and control measures established during the EVD outbreak have substantially improved self-reported provider practices for maternal and child health services in rural Guinea. However, more efforts are needed to maintain and sustain the gain achieved. PMID- 29595032 TI - Contraceptive Use, Unwanted Pregnancies and Abortions among Hairdressers in Ibadan, Southwest Nigeria. AB - The study was conducted in Ibadan, Southwest Nigeria to determine prevalence and predictors of contraceptive use, unwanted pregnancies and induced abortions among hairdressers. 1687 female hairdressers were surveyed using a cross sectional design and cluster sampling technique. Mean age was 27.0+/-8.1 years, 851 (50.4%) were single and 1005 (59.6%) qualified hairdressers. 817 (56.8%) of sexually active were currently using contraception. Attainment of secondary school education was a predictor of contraceptive use; OR=1.4, 95% CI (1.1-1.8). 429 (29.8%) ever had an unwanted pregnancy; 26.5 % among singles, 32.3 % among married. Predictors of unwanted pregnancies were age >30years; OR=1.9, 95% CI (1.4-2.5) and being a qualified hairdresser; OR=1.6, 95% CI (1.2-2.2). 347 (24.1%) ever had an induced abortion; 21.5.0 % of singles, 26% of married. Being married; OR=5.2, 95% CI (2.2-11.9) was the only predictor of induced abortion. Prevalence of unwanted pregnancies and abortions were high especially among married hairdressers. PMID- 29595033 TI - Surgical Treatment of Complication of Female Genital Mutilation in Pikine Hospital, Senegal. AB - We share our experience on reconstructive for surgery female genital mutilation. This is a retrospective study of all cases of female genital mutilation surgery performed in Pikine National Hospital. We have reviewed the various indications and surgical techniques used. We collected 8 cases of clitoral cyst and 6 cases of closed vaginal opening. The surgery of clitoral cysts was to perform cystectomy followed by nymphoplasty. The closing of the vaginal opening required defibulation together with clitoroplasty according to the wishes of the patient. The anatomical and functional outcomes were satisfactory. Female genital mutilation surgery requires a good knowledge of vulvar anatomy. The various surgical indications must meet the expectations of patients to guarantee their satisfaction. PMID- 29595034 TI - Retrograde intra-renal surgery under spinal anesthesia: the first large series. AB - BACKGROUND: Retrograde intra-renal surgery (RIRS) has become increasingly common and is mainly performed under general anesthesia (GA). There are no specific papers about RIRS performed under spinal anesthesia (SA). Our objective was to evaluate feasibility and results of RIRS performed under SA. METHODS: We analyzed all consecutive RIRS performed for stones in day surgery from March 2008 to September 2012. Single procedures outcomes of RIRS performed under SA were evaluated with US and KUB X-ray at 2 weeks. Further treatments, operative time and complications were also evaluated. Outcomes of RIRS performed under SA and GA were compared. Difference between groups was statistically analyzed. Significance level was set at P<0.05. RESULTS: One hundred thirty-nine RIRS under SA and 47 under GA were considered. Mean stone burden was 14+/-6 mm. No case of conversion from SA to GA occurred. Stone-free rate (SFR) level 4U of RIRS under SA and under GA were respectively 63.6% and 48.6%, SFR level 0U 24.5% and 25.7%, CIRF 39.1% and 22.9%. Further treatments were performed respectively in 20.8% and in 23.4%. No anesthesia-related and Clavien-Dindo grade >=3 complications occurred. No statistically significant difference was found in stone-free rates, CIRF and significant residual fragments rates, need for further procedures, operative time and complications between the two groups. CONCLUSIONS: RIRS under SA seems feasible and effective for renal stones in day surgery. Results seem equivalent to RIRS under GA. SA can be considered for RIRS as an alternative to GA. PMID- 29595035 TI - Prognostic role of delay before radical cystectomy: retrospective analysis of a single-centre cohort with 376 patients. AB - BACKGROUND: According to International Guidelines radical cystectomy (RC) should not be delayed over 90 days to prevent the risk of intercurrent progression and worse survival. Nevertheless, such a recommendation relies on a few retrospective studies reaching non-univocal conclusions. Aim of the present study was to investigate if the latency between diagnosis and cystectomy (LDC) is related to prognosis after RC. METHODS: Retrospective analysis of database collecting complete information on patients undergone RC at single institution since 2004. The cases with an LDC <15 or >360 days or submitted to neo-adjuvant chemotherapy or with distant metastasis were excluded. Uni- and multivariate analyses assessed the relationship between LDC upstaging, progression-free and overall survival. RESULTS: The data of 376 patients were analyzed; mean/median LDC was 83/76 days and 124 patients (33%) had LDC>90 days. LDC was shorter in younger patients with first diagnosis of more advanced BC at clinical staging; accordingly, patients with LDC<90 days had more advanced disease also at final pathology. Prevalence of pathological upstaging was 37%; in case of upstaging LDC was 75 days vs. 72 days (P=0.4629). Multivariable regression models adjusted for pathological local and lymph nodal stage showed that LDC, continuous or dichotomized at 30/60/90/120/180/240 days was not related to progression-free or overall survival. The retrospective design of study is the main limitation of the study. CONCLUSIONS: In our experience nor the risk of upstaging, neither survival after RC were related to LDC. Even if these results should not discourage any effort to perform surgery expeditiously, the window of opportunity for RC might not be delimited by a predetermined threshold. PMID- 29595036 TI - Association between lncRNA H19 (rs217727, rs2735971 and rs3024270) polymorphisms and the risk of bladder cancer in Chinese population. AB - BACKGROUND: The Long non-coding RNA (lncRNA) H19 is involved in carcinogenesis, progression, and metastasis. However, the association between genetic variants in H19 and bladder cancer susceptibility has not been reported. This case-control study assessed the association between H19 genetic variants and susceptibility to bladder cancer in a Chinese Han population. METHODS: In this study, 200 patients with bladder cancer and 200 healthy controls were surveyed and compared for frequencies of the genotypes of the H19 gene. Logistic regression analysis and the chi-square test were employed as statistical methods. Odds ratio (OR) and its corresponding 95% confidence interval (95% CI) were calculated to estimate the strength of association between H19 polymorphisms and risk of bladder cancer. RESULTS: We analyzed the frequency of three lncRNA H19 SNPs in 200 bladder cancer patients and 200 healthy controls. Carriers of variant rs217727 heterozygous genotype showed increased bladder cancer risk (P = 0.008). Further stratified analyses revealed that the association between bladder cancer risk and variant genotypes of rs217727 was more profound in smokers. Furthermore, decreased risk of invasive bladder cancer was found in carrying rs3024270 CC patients. CONCLUSIONS: Our results provided the evidence that rs217727 in H19 was associated with elevated risk of bladder cancer, which may be a potential biomarker for predicting bladder cancer susceptibility. Furthermore, invasive bladder cancer in carrying rs3024270 CC genotype maybe have a good prognosis. PMID- 29595037 TI - Expandable metallic ureteral stent: indications and results. AB - INTRODUCTION: Ureteral obstructions are managed by complex surgery not always feasible for surgical field complexity or poor patient conditions. Various surgical maneuvers, as ureteral dilation, stenting and percutaneous nephrostomy, can be offered, but they are related to considerable failure rates and negative impact on quality of life. In selected cases, the positioning of long-term expandable metallic ureteral stents (EMUSs) may be an appropriate and successful choice. EVIDENCE ACQUISITION: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria, a systematic review of the literature was performed in July 2017 using PubMed, Cochrane Library, Scopus and Web of Science databases. The search was conducted by typing the following terms: "Expandable metallic ureteral stent," "Memokath ureteral stent," "Allium ureteral stent," and "Uventa ureteral stent." EVIDENCE SYNTHESIS: Twenty studies reported the safety, efficacy and clinical outcomes related to the common available EMUSs. Most studies were single-arm, retrospective and involving a low number of clinical cases, resulting in significant difficulties with outlining indications and drawing conclusions. Available papers showed EMUSs offered a high rate of patency, a long duration and a good quality of life, even if they are associated with significant complications. CONCLUSIONS: Since the first description of ureteral stents 50 years ago, we have faced a significant evolution in stent design. The current generation of EMUSs offers many advantages, but the onset of adverse effects is still significant and limits their use to selected cases. Further research should be addressed to the realization of prospective, multi institutional randomized clinical trials to highlight indications to manage appropriately ureteral obstructions. PMID- 29595038 TI - The relationship between lower urinary tract symptoms and irritable bowel syndrome: a meta-analysis of cross-sectional studies. AB - INTRODUCTION: While several epidemiologic studies have investigated the relationship between lower urinary tract symptoms (LUTS) and irritable bowel syndrome (IBS), it remains unclear. To investigate the relationship between IBS and LUTS, a systematic review and meta-analysis of cross-sectional studies was carried out. EVIDENCE ACQUISITION: Online databases were searched up to December 1st, 2017 for cross-sectional studies that evaluated the association between IBS and the risk of LUTS. Summary odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. EVIDENCE SYNTHESIS: In all, 9 articles that contained 19907 participants and 2620 cases of LUTS were included in this meta-analysis. Compared with the non-IBS group, the IBS group had a higher risk of LUTS (total OR=2.11, 95% CI: 1.91-2.33, P<0.00001). Patients with IBS were more likely to have urine storage symptoms (total OR=1.80, 95% CI: 1.34-2.42, P<0.0001). Subgroup analysis by gender showed that the IBS group had a higher risk of LUTS in both men (total OR=2.17, 95% CI: 1.82-2.58, P<0.00001) and women (total OR=1.85, 95% CI: 1.57 2.17, P<0.00001). CONCLUSIONS: Our meta-analysis provides evidence that IBS is associated with an increased risk of LUTS in both men and women. PMID- 29595039 TI - An update on prostate biopsy in the era of magnetic resonance imaging. AB - INTRODUCTION: Prostate cancer (PCa) is a singular disease owing to absence of imaging technique able to detect suspicious glandular area at higher risk of disease. Nowadays, magnetic resonance imaging (MRI) has been used as a way to detect PCa and simplify targeting prostate biopsy (PB). The aim of this study is to review the most recent data regarding standard BP and MRI-guided PB. EVIDENCE ACQUISITION: A comprehensive systematic MEDLINE search was performed in December 2017 for English-language reports by using the following terms: "prostate biopsy," "multiparametric magnetic resonance imaging," "prostate cancer," "transrectal and transperineal ultrasound," "target biopsy." Previous published reviews and recent published original articles were preferred in order to meet our study scope. EVIDENCE SYNTHESIS: Retrieved studies of greater interest were reported in two main sections: standard PB and MRI-guided BP. Thus, the main items regarding PB were analyzed. Briefly, clinical suspicious of PCa is based on prostate specific antigen level and digital rectal examination findings although a PCa risk assessment through a nomogram risk calculator is nowadays advised. Ten eighteen biopsy cores, depending on prostate volume, and peripheral sampling seem the suitable scheme for initial biopsy while a saturation template (>20 cores including transitional prostate area) is widely used in case of repeat PB. Performing a local anesthesia is now the standard of care with several available techniques. No difference exists in term of PCa detection rate between transperienal and transrectal approaches however the last one is mostly used. The use of MRI-guided biopsy seems to be a promising imaging technique able to identify an index lesion at higher suspicious of PCa. In particular, MRI shows a higher accuracy than standard PB in the detection of clinically significant PCa. No general consensus exists on which MRI-guided biopsy should be used with three different ways currently available to take biopsy core. However, the initial MRI cognitive PB has been replaced by fusion MRI technique to guide biopsy with reproducible results. Absence of standardization founded in initial MRI studies has been recently revised by introduction of common criteria to assess PCa presence on MRI. CONCLUSIONS: PB is the cornerstone in diagnosis and management of PCa. Although ultrasound transrectal and transperineal PB are still considered as the standard, emerging data confirm the role of MRI-guided biopsy, particularly in patients with a previous negative biopsy. However, MRI costs and the moderate inter-reader reproducibility of the exam are still significant concerns requiring further studies to define the right role of MRI in the PCa diagnostic pathway. PMID- 29595040 TI - Male infertility as a proxy of the overall male health status. AB - INTRODUCTION: Male infertility (MI) has been widely associated with different comorbid conditions. The aim of this review is to summarize the available evidences investigating the link between MI cancer, chronic non-malignant conditions and overall health. EVIDENCE ACQUISITION: A literature search has been conducted using the MEDLINE/PubMed and Scopus databases for English-language original and review articles and selecting publications from January 2007 to June 2017, although highly regarded older publications were also considered. The following key words and MeSH terms were combined: "male infertility," "semen analysis," "health," "comorbidities," "cancer," "metabolic syndrome," "diabetes," "hypertension," "cardiovascular diseases," and "mortality." EVIDENCE SYNTHESIS: Several studies supported a higher risk of testis cancer for patients with MI; conversely, controversial findings have been reported on the association between prostate cancer and MI. Beside urogenital malignancies, melanoma, bladder, thyroid and hematological malignancies have been also more frequently reported among infertile men. Large cohort studies supported a significant association between diabetes mellitus, metabolic disorders and MI. Similarly, the risk of developing cardiovascular diseases appears to be higher among infertile men. Of note, a significant association between semen alterations and the overall burden of comorbidities, as well as the overall mortality, has been reported. A common genetic background appears as the main pathophysiological link between infertility and other comorbidities. CONCLUSIONS: Male infertility is a proxy of the overall male health status. Physicians should comprehensively assess men presenting for couple infertility and properly followed-up these patients given their higher risk of developing cancer. PMID- 29595041 TI - Time of catheterization as an independent predictor of early urinary continence recovery after radical prostatectomy. AB - BACKGROUND: The purpose of the present study was to investigate the potential impact of catheter removal time on immediate and early urinary continence recovery in a series of patients who underwent radical prostatectomy (RP). METHODS: We prospectively collected and analyzed the clinical records of 197 patients who underwent open RP between January 2014 and December 2016. A single surgeon using the urethral fixation technique performed all procedures. Patients receiving surgery between Monday and Wednesday performed a cystogram on postoperative day (POD) 2. Conversely, other cases treated on a Thursday or Friday performed a cystogram on the following Monday (POD 3 or 4). The catheter removal was planned the day after the cystogram if there was a watertight anastomosis or with a little extravasation (<5%). Urinary continence recovery was evaluated 1 week, 1, 2 and 3 months after catheter removal. Patients self reporting no urine leak were considered continent. Logistic regression analysis was used to identify independent predictors of urinary continence recovery at different follow-up durations. RESULTS: The median catheterization time was 3 (IQR: 3-4.2) days and acute urinary retention (AUR) was observed in 13 (6.5%) cases. At median follow-up of 12 (IQR: 9-12) months, no case of bladder neck contracture was observed. Urinary continence probabilities were 43%, 63%, 87%, 91% and 95% after 1 week, 1, 3, 6, and 12 months, respectively. On multivariable analyses, time of catheter removal was an independent predictor of urinary continence recovery after 1 week (OR 1.2; P=0.02); 1 month (OR 1.2; P=0.01); 3 months (OR 1.1; P=0.04) and 6 months (OR 1.1; P=0.03) after catheter removal. CONCLUSIONS: Time of catheterization should be considered as a postoperative parameter able to influence the immediate and early urinary continence recovery in patients undergoing RP. The impact of new surgical techniques on urinary continence recovery should be tested also considering such potential confounding factor. PMID- 29595042 TI - Does prostate volume have an impact on the functional and oncological results of Retzius-sparing robot-assisted radical prostatectomy? AB - BACKGROUND: The objective of our study is to evaluate the effect of prostatic volume on the outcomes of Retzius-sparing robot-assisted radical prostatectomy (RSP). METHODS: All the consecutive patients undergoing RSP up to January 2015 were included. The series was divided into three groups based on prostate weight at radical prostatectomy specimen (<40 g, 40-60 g, >60 g). Perioperative, oncological and functional data were prospectively recorded. Potency was defined as erections sufficient for penetration; continence as no pad or one safety liner. Oncological results were reported as positive surgical margins (PSMs) and 1-year biochemical disease-free survival (PSA<0.2 ng/mL). RESULTS: We evaluated 750 patients (366 with <40 g prostates, 272 with 40-60 g prostates, 112 with >60 g prostates). Median follow-up was 22 months; PSA was higher in larger prostates (6.6 vs. 6.8 vs. 8 ng/mL). Nerve-sparing and bladder-neck sparing procedures were in similar percentages. Larger prostates required longer surgeries (90 vs. 100 vs. 100 minutes, P=0.002). Perioperative results were similar (blood loss, discharge, complications, catheter removal). Larger prostates had more frequently localized disease (pT2 in 49.5% vs. 60.7% vs. 68.5%; P=0.001); PSMs were similar both in pT2 (15.5% vs. 9.4% vs. 11.8%) and in pT3 cases (40.1% vs. 42% vs. 34%). In the three study groups, immediate continence was reached by 88%, 89.5% and 81.3% (P=0.045), while no differences were observed concerning continence (93.4%, 94.1%, 94.7%; P=0.892) or potency after follow-up. CONCLUSIONS: RSP is feasible in patients with prostates of any volume, with similar oncological and functional outcomes. Despite being inferior to the figures obtained in low volume prostates, the very high immediate continence rates observed in larger prostates encourage the use of this approach also in larger prostates. PMID- 29595043 TI - Minimally invasive approach for the management of urological complications after renal transplantation: single center experience. AB - BACKGROUND: The aim of the study was to characterise urological complications after renal transplantation and to evaluate the role of minimally invasive management for urological complications. METHODS: A total of 920 kidney transplantations were performed between 2008 and 2015. All patients were followed up for at least 1 year after transplantation. Complications regarded as urological were urinary leakage, ureteral stricture, urinary malignancy, bladder outlet obstruction (BOO) and urinary calculi. We evaluated data from the time of occurrence of urological complications and the type of the management prescribed. RESULTS: Among 920 transplantations performed in our clinic, 41 (4.4%) urological complications arose. Twenty (48.8%) of the complications occurred during the first 3 months and 21 (51.2%) occurred after 3 months, postoperatively. Ureteral strictures were found in 14 (34.1%) patients, urinary tract stones in seven (17%), BOO in 6 (14.6%) and urinary leakage was observed in 5 (12.1%) patients. Ureteral stricture was managed with endoscopic approach in eight (61.3%) patients. Urinary tract stones and urinary leakage were managed in 7 (100%) and 4 (75%) patients with endoscopic approach. Overall 29 (70.7%) of 41 urological complications were managed with endourological approaches. CONCLUSIONS: It is likely that the importance of open surgery could decrease in the future. Endoscopic management of urological complications have come to have an important role in the treatment of urological complications after transplantation. PMID- 29595045 TI - The endoscopic surgical resection of intrasellar lesions conserves the hormonal function: a negative correlation to the microsurgical technique. AB - BACKGROUND: The endonasal endoscopic approach is still currently under investigation for sellar tumour surgery: a higher resection rate is to be expected and complications should be minimized. The authors report their surgical results of endonasal endoscopic neurosurgery with special focus on postoperative hypopituitarism in comparison to microsurgical procedures. METHODS: Sixty patients received endoscopic endonasal transsphenoidal procedures for sellar pathologies. All patients were followed up prospectively. A second group of 60 patients received microsurgical transsphenoidal procedures for sellar pathologies in our neurosurgical department before and were prospectively followed until now. Special attention was paid to hormonal insufficiency and medical substitution. RESULTS: Sixty-eight percentage (41/60) of the patients who underwent microsurgical procedures showed a new persisting pituitary insufficiency postoperatively. Twenty-three patients (55.5%) were substituted with thyroxine, hydrocortisone and sexual hormones and one patient (2.5%) also with ADH cause of global pituitary insufficiency. In 19 cases without any hormonal insufficiency after microsurgical procedures 9 patients (47%) showed remnant tumor in follow up MRI. The patients who underwent endoscopic procedures for pituitary adenomas revealed significant (p<0.01) less new persistent hormonal insufficiency with 13% of all cases (8/60). Five patients (62.5%) were substituted with thyroxine and hydrocortisone, two patients (25%) substituted with thyroxine, hydrocortisone and sexual hormones and one patient also with ADH because of global pituitary insufficiency. Thereby, in follow up MRI and hormonal testing, radical tumour resection was detected in 92% in the endoscopic group. CONCLUSIONS: This study seems to indicate that a better intraoperative identification and preservation of pituitary gland is possible in endoscopic transsphenoidal surgery with consecutive lower postoperative hypopituitarism rate. PMID- 29595044 TI - Robotic-assisted laparoscopic repair of ureteral injury: an evidence-based review of techniques and outcomes. AB - INTRODUCTION: Iatrogenic ureteral injuries represent a common surgical problem encountered by practicing urologists. With the rapidly expanding applications of robotic-assisted laparoscopic surgery, ureteral reconstruction has been an important field of recent advancement. This collaborative review sought to provide an evidence-based analysis of the latest surgical techniques and outcomes for robotic-assisted repair of ureteral injury. EVIDENCE ACQUISITION: A systematic review of the literature up to December 2017 using PubMed/Medline was performed to identify relevant articles. Those studies included in the systematic review were selected according to Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria. Additionally, expert opinions were included from study authors in order to critique outcomes and elaborate on surgical techniques. A cumulative outcome analysis was conducted analyzing comparative studies on robotic versus open ureteral repair. EVIDENCE SYNTHESIS: Thirteen case series have demonstrated the feasibility, safety, and success of robotic ureteral reconstruction. The surgical planning, timing of intervention, and various robotic reconstructive techniques need to be tailored to the specific case, depending on the location and length of the injury. Fluorescence imaging can represent a useful tool in this setting. Recently, three studies have shown the feasibility and technical success of robotic buccal mucosa grafting for ureteral repair. Soon, additional novel and experimental robotic reconstructive approaches might become available. The cumulative analysis of the three available comparative studies on robotic versus open ureteral repair showed no difference in operative time or complication rate, with a decreased blood loss and hospital length of stay favoring the robotic approach. CONCLUSIONS: Current evidence suggests that the robotic surgical platform facilitates complex ureteral reconstruction in a minimally invasive fashion. High success rates of ureteral repair using the robotic approach mirror those of open surgery, with the additional advantage of faster recovery. Novel techniques in development and surgical adjuncts show promise as the role of robotic surgery evolves. PMID- 29595046 TI - Brain arteriovenous malformations: an ongoing challenge. PMID- 29595047 TI - Natural history of brain arteriovenous malformations: systematic review. AB - INTRODUCTION: The appropriate interpretation of natural history of brain arteriovenous malformations (bAVMs) and of factors that negatively affect the risk of future hemorrhage are important when recommending management pathways. With the present systematic review, we aim to provide an overview of the available evidence on natural history of brain arteriovenous malformations (bAVMs), focusing on hemorrhage rates and risk factors for future hemorrhage. EVIDENCE ACQUISITION: We performed a systematic literature analysis using the Ovid Medline database, encompassing English language studies (published between 1980 and 2018) reporting the natural history of untreated bAVMs. Annual hemorrhage rates in both unruptured and previously ruptured bAVMs, as well as risk factors for future hemorrhage were extracted for analysis. EVIDENCE SYNTHESIS: Eighteen studies with a total of 8418 bAVM-cases could be extracted from the literature. Seventeen studies reported annual hemorrhage rates and ten studies reported risk factors for future hemorrhage. The average annualized hemorrhage rate was 2.2% for unruptured bAVMs and 4.3%, for bAVMs that presented with hemorrhage. Prior hemorrhage and deep AVM location could be identified as most consistently reported risk factors for future hemorrhage. CONCLUSIONS: Previously ruptured bAVMs have a higher annual hemorrhage rate than unruptured bAVMs. Deep bAVM location and prior hemorrhage may increase the risk for subsequent hemorrhage.

PMID- 29595049 TI - Adjusting the Linear Range of Au-MOF Fluorescent Probes for Real-Time Analyzing Intracellular GSH in Living Cells. AB - A series of Au-loaded metal-organic frameworks (MOFs) were synthesized in this study and further employed for real-time quantitative analysis of intracellular glutathione (GSH) level. Different linear ranges can be acquired by altering the size of gold and MOF particles, or adjusting the proportion of 2 aminoterephthalic acid/1,4-benzenedicarboxylate linkers, which is also observed on fluorescein isothiocyanate-attached Au-MOFs. Further study reveals that the flexible molecular chain of GSH with the -COOH/-NH2 and -SH terminals may readily tie on relevant gold nanoparticles through its -NH2/-COOH groups, which then restricts the intramolecular motions of fluorescence probes and thus induces marked fluorescence enhancement. On the basis of these observations, the intracellular GSH levels of different cells including L02 cells, Hela, and U87 as well as HepG2 cancer cells can be rapidly evaluated by these Au-MOF probes.

However, it is brittle and susceptible of inactivation of reactive oxygen species (ROS) immoderate production. Here, we demonstrated that MoS2 nanosheets (few-layer MoS2), as a multifunctional nanozyme, possess intrinsic activity of mimicking enzymes of superoxide dismutases (SODs), catalases (CATs), and peroxidases (PODs) under physiological conditions (pH 7.4, 25 degrees C). Further, MoS2 nanosheets showed POD-like activity by transferring electrons instead of generating ROS. Similar to EAS, a defense termed nanozymatic antioxidant system (NAS) was developed by MoS2 nanosheets, for regulation of oxidative stress. Surprisingly, this NAS can effectively scavenge other free radicals including hydroxyl radicals (*OH), nitrogen-centered free radicals (*DPPH), and nitric oxide (*NO). To evaluate these unique properties of MoS2 based NAS in vivo, Escherichia coli ( E. coli), Staphylococcus aureus ( S. aureus), and A549 cell models were established, respectively. These results showed MoS2 nanosheets superiorly protect bacteria and cells against oxidative injury caused by H2O2. This work makes MoS2 nanosheets promising antioxidants in the pathological processes and expands their application in biocatalysis and nano biomedicine. PMID- 29595051 TI - Construction of Highly Efficient Resonance Energy Transfer Platform Inside a Nanosphere for Ultrasensitive Electrochemiluminescence Detection. AB - Electrochemiluminescence (ECL) detection has attracted increasing attention as a promising analytical approach. A considerable number of studies showed that ECL intensity can be definitely improved by resonance energy transfer (RET), while the RET efficiency is strongly dependent on the distance between exited donors and acceptors. Herein we disclose for the first time a highly enhanced RET strategy to promote the energy transfer efficiency by coencapsulating the donor ([Ru(bpy)3]2+)/acceptor (CdTe quantum dots, CdTe QDs) pairs into a silica nanosphere. Plenty of [Ru(bpy)3]2+ and CdTe QDs closely packed inside a single nanosphere greatly shortens the electron-transfer path and increases the RET probability, therefore significantly enhancing the luminous efficiency. Further combining with molecularly imprinting technique, we develop a novel ECL sensor for ultrasensitive and highly selective detection of target molecules. Proof of concept experiments showed that extremely low detection limits of subfg/mL (S/N = 3) with broad linear ranges (fg/mL to ng/mL) could be obtained for detection of two kinds of mycotoxins (alpha-ergocryptine and ochratoxin A) that are recognized as potential health hazards at very low concentrations. This strategy combining enhanced RET system and molecularly imprinting technique, represents a versatile ECL platform toward low-cost, rapid, ultrasensitive, and highly selective detection of target molecules in diverse applications. PMID- 29595052 TI - Mucoadhesion of Progesterone-Loaded Drug Delivery Nanofiber Constructs. AB - Mucoadhesive delivery systems have attracted remarkable interest recently, especially for their potential to prolong dosage form resident times at sites of application such as the vagina or nasal cavity, thereby improving convenience and compliance as a result of less frequent dosage. Mucoadhesive capabilities need to be routinely quantified during the development of these systems. This is however logistically challenging due to difficulties in obtaining and preparing viable mucosa tissues for experiments. Utilizing artificial membranes as a suitable alternative for quicker and easier analyses of mucoadhesion of these systems is currently being explored. In this study, the mucoadhesive interactions between progesterone-loaded fibers (with varying carboxymethyl cellulose (CMC) content) and either artificial (cellulose acetate) or mucosa membranes are investigated by texture analysis and results across models are compared. Mucoadhesion to artificial membrane was about 10 times that of mucosa, though statistically significant ( p = 0.027) association between the 2 data sets was observed. Furthermore, a hypothesis relating fiber-mucosa interfacial roughness (and unfilled void spaces on mucosa) to mucoadhesion, deduced from some classical mucoadhesion theories, was tested to determine its validity. Points of interaction between the fiber and mucosa membrane were examined using atomic force microscopy (AFM) to determine the depths of interpenetration and unfilled voids/roughness, features crucial to mucoadhesion according to the diffusion and mechanical theories of mucoadhesion. A Kendall's tau and Goodman-Kruskal's gamma tests established a monotonic relationship between detaching forces and roughness, significant with p-values of 0.014 and 0.027, respectively. A similar relationship between CMC concentration and interfacial roughness was also confirmed. We conclude that AFM analysis of surface geometry following mucoadhesion can be explored for quantifying mucoadhesion as data from interfacial images correlates significantly with corresponding detaching forces, a well-established function of mucoadhesion.

AB - To accomplish an innovative vaccine design, there are two key challenges: developing formulations that avoid cold chain shipment and finding a delivery vehicle that is absorbable in vivo. Here, we explored the design and performance of a colloidal vesicle that enabled us to consider both challenges. We used polymeric bioresorbable amphiphiles as surface-active agents for stabilizing oily/aqueous interfaces and formed a colloidal vehicle named polysorbasome (PSS, polymeric absorbable vesicle), without using conventional emulsifiers such as sorbitan esters or their ethoxylates. Homogenizing the oil/water compartments forms a colloid containing an aqueous solution in its core and provides an oily barrier that isolates the encapsulated material from external materials. In this form, the PSS serves as a depot for sustained delivery of vaccine antigens. Following vaccination, the antigen-specific antibodies and the cell-mediated immunity can be manipulated after the antigen being formulated with PSS particles. Then, the degradability intrinsic to the polymeric bioresorbable amphiphiles complies with the destruction and further absorbance of the vehicles in vivo. The structural features of these versatile vesicles based on bioresorbable amphiphilic engineering may provide new insights into vaccine delivery. PMID- 29595055 TI - Coumarin-Based Oxime Esters: Photobleachable and Versatile Unimolecular Initiators for Acrylate and Thiol-Based Click Photopolymerization under Visible Light-Emitting Diode Light Irradiation. AB - Developing efficient unimolecular visible light-emitting diode (LED) light photoinitiators (PIs) with photobleaching capability, which are essential for various biomedical applications and photopolymerization of thick materials, remains a great challenge. Herein, we demonstrate the synthesis of a series of novel PIs, containing coumarin moieties as chromophores and oxime ester groups as initiation functionalities and explore their structure-activity relationship. The investigated oxime esters can effectively induce acrylates and thiol-based click photopolymerization under 450 nm visible LED light irradiation. The initiator O-3 exhibited excellent photobleaching capability and enabled photopolymerization of thick materials (~4.8 mm). The efficient unimolecular photobleachable initiators show great potential in dental materials and 3D printings. PMID- 29595054 TI - High-Output Lead-Free Flexible Piezoelectric Generator Using Single-Crystalline GaN Thin Film. AB - Piezoelectric generators (PEGs) are a promising power source for future self powered electronics by converting ubiquitous ambient mechanical energy into electricity. However, most of the high-output PEGs are made from lead zirconate titanate, in which the hazardous lead could be a potential risk to both humans and environment, limiting their real applications. III-Nitride (III-N) can be a potential candidate to make stable, safe, and efficient PEGs due to its high chemical stability and piezoelectricity. Also, PEGs are preferred to be flexible rather than rigid, to better harvest the low-magnitude mechanical energy. Herein, a high-output, lead-free, and flexible PEG (F-PEG) is made from GaN thin film by transferring a single-crystalline epitaxial layer from silicon substrate to a flexible substrate. The output voltage, current density, and power density can reach 28 V, 1 MUA.cm-2, and 6 MUW.cm-2, respectively, by bending the F-PEG. The generated electric power by human finger bending is high enough to light commercial visible light-emitting diodes and charge commercial capacitors. The output performance is maintained higher than 95% of its original value after 10 000-cycle test. This highly stable, high-output, and lead-free GaN thin-film F PEG has the great potential for future self-powered electronic devices and systems. PMID- 29595056 TI - Live Cell Imaging in Microfluidic Device Proves Resistance to Oxygen/Glucose Deprivation in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes. AB - Analyses of cellular responses to fast oxygen dynamics are challenging and require ad hoc technological solutions, especially when decoupling from liquid media composition is required. In this work, we present a microfluidic device specifically designed for culture analyses with high resolution and magnification objectives, providing full optical access to the cell culture chamber. This feature allows fluorescence-based assays, photoactivated surface chemistry, and live cell imaging under tightly controlled pO2 environments. The device has a simple design, accommodates three independent cell cultures, and can be employed by users with basic cell culture training in studies requiring fast oxygen dynamics, defined media composition, and in-line data acquisition with optical molecular probes. We apply this technology to produce an oxygen/glucose deprived (OGD) environment and analyze cell mortality in murine and human cardiac cultures. Neonatal rat ventricular cardiomyocytes show an OGD time-dependent sensitivity, resulting in a robust and reproducible 66 +/- 5% death rate after 3 h of stress. Applying an equivalent stress to human induced pluripotent stem cell derived cardiomyocytes (hiPS-CMs) provides direct experimental evidence for fetal like OGD-resistant phenotype. Investigation on the nature of such phenotype exposed large glycogen deposits. We propose a culture strategy aimed at depleting these intracellular energy stores and concurrently activate positive regulation of aerobic metabolic molecular markers. The observed process, however, is not sufficient to induce an OGD-sensitive phenotype in hiPS-CMs, highlighting defective development of mature aerobic metabolism in vitro. PMID- 29595058 TI - Inkjet Printing Based Droplet Generation for Integrated Online Digital Polymerase Chain Reaction. AB - We report on the development of a novel and flexible online digital polymerase chain reaction (dPCR) system. The system was composed of three parts: an inkjet for generating the droplets, a coiled fused-silica capillary for thermal cycling, and a laser-induced fluorescence detector (LIFD) for positive droplet counting. Upon inkjet printing, monodisperse droplets were continuously generated in the oil phase and then introduced into the capillary in the form of a stable dispersion. The droplets containing one or zero molecules of target DNA passed through the helical capillary that was attached to a cylindrical thermal cycler for PCR amplification, resulting in the generation of fluorescence for the DNA positive droplet. After 36 PCR cycles, the fluorescence signal intensity was detected by laser-induced fluorescence located at the downstream of the capillary, followed by a positive/negative counting. The present system was successfully applied to the absolute quantification of the HPV sequence in Caski cells with dynamic ranges spanning 4 orders of magnitude. PMID- 29595057 TI - Accurately Predicting Disordered Regions of Proteins Using Rosetta ResidueDisorder Application. AB - Although many proteins necessitate well-folded structures to properly instigate their biological functions, a large fraction of functioning proteins contain regions-known as intrinsically disordered protein regions-where stable structures are not likely to form. Notable functional roles of intrinsically disordered proteins are in transcriptional regulation, translation, and cellular signal transduction. Moreover, intrinsically disordered protein regions are highly abundant in many proteins associated with various human diseases, therefore these segments have become attractive drug targets for potential therapeutics. Over the past decades, numerous computational methods have been developed to accurately predict disordered regions of proteins. Here we introduce a user-friendly and reliable approach for the prediction of disordered protein regions using the structure prediction software Rosetta. Using 245 proteins from a benchmark data set (16 DisProt database proteins) and a test data set (229 proteins with NMR data), we use Rosetta to predict the global protein structures and then show that there is a statistically significant difference between Rosetta scores in disordered and ordered regions, with scores being less favorable in disordered regions. Furthermore, the difference in scores between ordered and disordered protein regions is sufficient to accurately identify disordered protein regions. As a result, our Rosetta ResidueDisorder method (benchmark data set prediction accuracy of 71.77% and independent test data set prediction accuracy of 65.37%) outperformed other established disorder prediction tools and did not exhibit a biased prediction toward either ordered or disordered regions. To facilitate usage, a Rosetta application has been developed for the Rosetta ResidueDisorder method. PMID- 29595059 TI - Chiral Sensing Platform Based on the Self-Assemblies of Diphenylalanine and Oxalic Acid. AB - Molecular self-assemblies offer a promising strategy for the synthesis of advanced materials for the construction of novel chiral sensing systems, and latest innovations on such self-assemblies are focused on simple building blocks in biology such as nucleic acids, lipids, and peptides. Herein, the self assemblies of diphenylalanine (FF) and oxalic acid (OA) were prepared as the chiral sensing device for the recognition of tryptophan (Trp) isomers. Interestingly, the self-assemblies composed of OA and FF with different charging states (neutral, positively charged, and negatively charged) exhibited quite different morphologies, resulting in significantly different chiral recognition ability toward the Trp isomers. Also, in this work, the temperature sensitivity and chiral selectivity of the proposed FF-OA self-assemblies were also studied. From a practical point of view, the FF-OA self-assemblies were finally applied for the determination of precise levels of d-Trp in the racemic mixture of Trp isomers. PMID- 29595060 TI - The effect of partner HIV status on motivation to take antiretroviral and isoniazid preventive therapies: a conjoint analysis. AB - Antiretroviral therapy (ART) and isoniazid preventive therapy (IPT) are important to reduce morbidity and mortality among people newly diagnosed of HIV. The successful uptake of ART and IPT requires a comprehensive understanding of patients' motivation to take such therapies. Partners also play an important role in the decision to be initiated and retained in care. We quantified patients' motivation to take preventive therapies (ART and IPT) and compared by partner HIV status among people newly diagnosed of HIV. We enrolled and surveyed adults (>=18 years) with a recent HIV diagnosis (<6 months) from 14 public primary care clinics in Matlosana, South Africa. Participants received eight forced-choice tasks comparing two mutually exclusive sub-sets of seven possible benefits related to preventive therapies. A linear probability model was fitted to estimate the probability of prioritizing each benefit. Tests of concordance were conducted across partner HIV status (no partner, HIV- or unknown, or HIV+). A total of 424 people completed surveys. At the time of interview, 272 (64%) were on ART and 334 (79%) had a partner or spouse. Keeping themselves healthy for their family was the most important motivator to take preventive therapies (p < 0.001). Preventing HIV transmission to partners was also highly prioritized among participants with current partners independent of partner's HIV status (p < 0.001), but it was least prioritized among those without current partners (p = 0.72). Keeping themselves healthy was less prioritized. We demonstrate that social responsibility such as supporting family and preventing HIV transmission to partners may pose greater motivation for ART and IPT initiation and adherence compared to individual health benefits. These messages should be emphasized to provide effective patient-centered care and counseling. PMID- 29595061 TI - Continuous Glucose Monitoring Associated With Less Diabetes-Specific Emotional Distress and Lower A1c Among Adolescents With Type 1 Diabetes. AB - BACKGROUND: Psychosocial impact research of continuous glucose monitoring (CGM) and continuous subcutaneous insulin infusion (CSII) among adolescents with type 1 diabetes (T1D) is limited. The present study assesses associations between diabetes technology use on adolescent- and parent-perceived diabetes-specific distress and A1c. METHOD: Adolescents with T1D and parents (N = 1040; primarily mothers) completed measures of diabetes distress. Adolescents were categorized by technology use: CGM Alone, CSII Alone, CGM+CSII, or No Technology. ANOVA, regression, and Cohen's d were used for group comparisons on measures of diabetes distress and A1c. Analyses also compared groups on clinical elevations of distress. RESULTS: CGM use was associated with less adolescent distress compared to No Technology ( d = 0.59), CGM+CSII ( d = 0.26), and CSII Alone ( d = 0.29). Results were similar but with smaller effect size for parent-reported distress, although CGM+CSII showed equivocal association with parent distress compared to No Technology ( d = 0.18). CGM Alone was associated with lower A1c compared to No Technology ( d = 0.48), to CSII Alone ( d = 0.37), and was comparable to CGM+CSII ( d = 0.03). CGM+CSII conferred advantage over CSII Alone ( d = 0.34). Clinical elevation of distress was associated with not using any technology particularly for adolescents. CONCLUSIONS: Technology use is associated with lower adolescent distress than lower parent distress. CGM Alone is associated with lower adolescent and parent distress than CSII or CGM+CSII. This appears to be clinically meaningful based on cut scores for measures. CGM is associated with lower A1c independent of being used alone or with CSII. PMID- 29595062 TI - Tendoscopic Treatment of Peroneal Intrasheath Subluxation: A New Subgroup With Superior Peroneal Retinaculum Injury. AB - BACKGROUND: Snapping peroneal tendons is a rare cause of lateral ankle pain. Two subgroups have been described: chronic subluxation with superior peroneal retinaculum (SPR) injury and intrasheath subluxation with SPR intact. The aim of the study was to report the tendoscopic findings and results in patients affected by snapping peroneal tendons without evident dislocation. METHODS: Between 2010 and 2015, a total of 18 patients with a retromalleolar "click" sensation and no clinical signs of peroneal tendon dislocation underwent tendoscopy. Mean age was 29 years (range, 18-47). Mean follow-up was 45 months (range, 18-72). RESULTS: Tendoscopic examination revealed an intact SPR in 12 patients. Of these 12, a space-occupying lesion was present in 7, a superficial tear of peroneus brevis in 4, and a shallow fibular groove in 7. An SPR injury without peroneal tendon dislocation was observed in the remaining 6 patients. All these 6 patients presented a shallow fibular groove. Although the SPR was injured, they had been diagnosed as intrasheath subluxation. Patients with intrasheath subluxation and intact SPR underwent debridement of a space-occupying lesion in 11 cases and fibular groove deepening in 5 cases. Patients with intrasheath subluxation and SPR injury underwent fibular groove deepening without addressing the SPR. At follow-up, the mean American Orthopaedic Foot & Ankle Society score increased from 76 (range, 69-85) preoperatively to 97 (range, 84-100). No recurrence or major complications were reported. Conclusion Intrasheath subluxation of peroneal tendons was successfully treated tendoscopically. A new subgroup of intrasheath subluxation with SPR injury but no clinically evident peroneal tendon dislocation is reported. LEVEL OF EVIDENCE: Level IV, case series. PMID- 29595063 TI - 3-Monochloropropane-1,2-diol (alpha-chlorohydrin) disrupts spermatogenesis and causes spermatotoxicity in males of the Egyptian fruit-bat (Rousettus aegyptiacus). AB - We evaluated the sterilizing effect of 3-monochloropropane-1, 2-diol (3-MCPD) in male Egyptian fruit bats (Rousettus aegyptiacus). We used three groups. One was treated with 70 mg/kg 3-MCPD for 4 days. The second group was treated with 3-MCPD as a bait formulation (known concentration of 3-MCPD mixed with a known amount of food). The third group was untreated controls. We compared the weights of the reproductive organs, histology of the testes, occurrence of spermatogenesis, and the count, motility and abnormalities of epididymal sperm of treated males with those of the untreated control group. 3-MCPD caused significantly decreased weights of reproductive organs, several testicular histological alterations and spermatogenic arrest accompanied by significant decreases in sperm count and motility, and significantly increased number of abnormal sperm. 3-MCPD bait was readily accepted by the animals. 3-MCPD, even in low doses and after limited exposure, disrupted spermatogenesis in males of the Egyptian fruit bat. Our findings have potential value for public health and agricultural authorities, and for vertebrate pest managers. 3-MCPD may have application for control of this pest. PMID- 29595064 TI - Accelerating drug development in pediatric cancer: a novel Phase I study design of venetoclax in relapsed/refractory malignancies. AB - Venetoclax is a highly selective, potent BCL-2 inhibitor that is approved for some patients previously treated for chronic lymphocytic leukemia, and has shown promising activity in adult studies across several hematologic malignancies. Preclinical studies have demonstrated venetoclax activity in pediatric patient derived xenograft models and cell lines; however, clinical studies in pediatric patients have yet to be conducted. The prognosis is poor for children with most relapsed/refractory malignancies, and limited treatment options result in unmet clinical need. Herein, we describe the rationale and design of the first study of venetoclax in pediatric patients with relapsed/refractory malignancies: a Phase I trial investigating the safety and pharmacokinetics of venetoclax monotherapy followed by the addition of chemotherapy (Trial registration: EudraCT 2017-000439 14; NCT03236857). PMID- 29595065 TI - Protease inhibitor therapy for hepatitis C virus-infection. AB - INTRODUCTION: The hepatitis C virus (HCV) has affected an estimated of 80 million individuals worldwide and is a strain on public health. Around 25-30% of patients in Europe and the US who are infected with HIV are coinfected with HCV. Prior to 2013, treatment modalities containing an NS3/4A protease inhibitor in combination with pegylated interferon and ribavirin improved sustained virological response (SVR) rates. However, rates of severe side effects were high. Nowadays, oral direct-acting antiviral (DAA) combination therapy offers excellent treatment efficacy, safety and tolerability. Areas covered: This review focuses on the current literature and clinical evidence and their impact regarding NS3/4A protease inhibitors. The pitfalls encountered in treating HIV- and HBV-coinfected patients are also discussed. Expert opinion: In the era of DAA treatment, third generation pan-genotypic NS3/4A protease inhibitors (mainly glecaprevir and voxilaprevir) show high antiviral activity and a genetic resistance barrier with cure rates of over 95% when combined with an NS5A inhibitor, irrespective of baseline resistance associated variants (RASs) being present. These new key components of DAA combination therapy are impressive options to eradicate HCV in the so-called difficult-to-treat population (e.g. compensated cirrhosis, end stage renal disease and patients who failed previous DAA treatment). PMID- 29595066 TI - Follicular fluid levels of anti-Mullerian hormone, insulin-like growth factor 1 and leptin in women with fertility disorders. AB - : Anti-Mullerian hormone (AMH), insulin-like growth factor 1 (IGF1) and leptin are produced in the granulosa cells of follicles and play an important role in the growth and maturation of follicles. The aim of our study was to monitor AMH, IGF1 and leptin levels in a group of healthy women and compare them to a group of women with fertility disorders. The second aim was the evaluation of biomarker levels in relation to the identified cause of infertility. Totally, 146 females were enrolled into our study. Seventy-two healthy controls and seventy-four females with fertility disorders were divided into four subgroups: anovulation, endometriosis, fallopian tube damage, unknown reason. IGF1 was the only biomarker with significantly lower levels throughout the entire group with fertility disorders. We did not identify any statistically significant differences for AMH and leptin. Regarding subgroups, significant differences were only observed in the group of anovulatory women. AMH and leptin showed higher levels while IGF1 showed lower levels. In conclusion, levels of AMH, IGF1 and leptin found in follicular fluid are sensitive markers for anovulatory fertility disorders. AMH, IGF1 and leptin levels in follicular fluid have no relation to the fertility disorders caused by endometriosis, fallopian tube damage or disorders with unknown etiology. ABBREVIATIONS: AMH: anti-Mullerian hormone; IGF1: insulin-like growth factor 1; PCOS: polycystic ovary syndrome.

AB - A new stereoisomer Meso-araguspongine C together with nine reported macrocyclic bis-quinolizidine alkaloids araguspongines A, C, E, L, N-P, petrosin, and petrosin A were isolated from marine sponge Xestospongia muta. Stereochemistry of meso-araguspongine C (2) and araguspongines N-P (3-5) were established by their NMR data and conformational analyses. Both araguspongine C (1) and meso araguspongine C (2) exhibited great cytotoxic activity towards HepG-2, HL-60, LU 1, MCF-7, and SK-Mel-2 human cancer cells (IC50 in the range of 0.43-1.02 MUM).

PMID- 29595070 TI - The Anticancer Effects of Garlic Extracts on Bladder Cancer Compared to Cisplatin: A Common Mechanism of Action via Centromere Protein M. AB - Although garlic induces apoptosis in cancer cells, it is unclear whether the effects are similar to those of cisplatin against bladder cancer (BC). Therefore, this study investigated whether garlic extracts and cisplatin show similar activity when used to treat BC. The effect of garlic on T24 BC cell line was examined in a BALB/C-nude mouse xenograft model and compared with that of cisplatin. Tissue microarray analysis and gene network analysis were performed to identify differences in gene expression by control tumors and tumors exposed to garlic extract or cisplatin. Investigation of gene expression based on tissues from 165 BC patients and normal controls was then performed to identify common targets of garlic and cisplatin. Tumor volume and tumor weight in cisplatin (0.05[Formula: see text]mg/kg)- and garlic-treated mice were significantly smaller than those in negative control mice. However, cisplatin-treated mice also showed a significant reduction in body weight. Microarray analysis of tumor tissue identified 515 common anticancer genes in the garlic and cisplatin groups ([Formula: see text]). Gene network analysis of 252 of these genes using the Cytoscape and ClueGo software packages mapped 17 genes and 9 gene ontologies to gene networks. BC (NMIBC and MIBC) patients with low expression of centromere protein M (CENPM) showed significantly better progression-free survival than those with high expression. Garlic extract shows anticancer activity in vivo similar to that of cisplatin, with no evident of side effects. Both appear to act by targeting protein-DNA complex assembly; in particular, expression of CENPM. PMID- 29595071 TI - Total Flavones of Abelmoschus manihot Exhibits Pro-Angiogenic Activity by Activating the VEGF-A/VEGFR2-PI3K/Akt Signaling Axis. AB - Angiogenesis is a process of new blood vessel formation from pre-existing vessels. Vascular endothelial growth factor-A (VEGF-A) binds to VEGF receptor-2 (VEGFR2) and thus activation of phosphatidylinositol 3-kinase (PI3K)/Akt pathway play a central role in angiogenesis. Total flavones of Abelmoschus manihot (TFA), the major active component of the traditional Chinese herb Abelmoschus manihot, display novel pro-angiogenic activity. However, little information concerning its underlying mechanism is available. Here we investigate the pro-angiogenesis of TFA with the aim of understanding its mechanism of action. Human umbilical vein endothelial cells (HUVECs) and the chick chorioallantoic membrane (CAM) model were used to evaluate pro-angiogenesis of TFA using cell viability, wounding healing, transwell invasion, tube formation, RT-qPCR and Western blot methods. LY294002, a PI3K inhibitor, was used to interfere with PI3K/Akt pathway signal for assessing the underlying mechanism. Results in vitro indicated TFA obviously promoted HUVECs proliferation, migration, invasion and tube formation. Furthermore, TFA markedly augmented PI3K and Akt phosphorylation and up-regulated VEGF-A and VEGFR2 expression in HUVECs. However, pre-treatment with LY294002 not only markedly attenuated TFA-induced cells proliferation, migration, invasion and tube formation, but also significantly abolished TFA-induced VEGF-A and VEGFR2 over-expression as well as PI3K and Akt phosphorylation. Experiments in CAM model showed TFA significantly promoted the formation of branched blood vessels and was dramatically suppressed by LY294002. Taken together, TFA promoted angiogenesis both in vitro and in vivo which, however, were counteracted by LY294002, suggesting at least in part, TFA exhibits pro-angiogenic activity by activating the VEGF-A/VEGFR2-PI3K/Akt signaling axis. PMID- 29595072 TI - Platycodin D Reverses Pathological Cardiac Hypertrophy and Fibrosis in Spontaneously Hypertensive Rats. AB - Platycodin D (PD) is the main active saponin isolated from Platycodon grandiflorum (PG) and is reported to exhibit anticancer, anti-angiogenic, anti inflammation and anti-obesity biological effects. The current study aims to evaluate the therapeutic efficacy of PD in cardiac fibrosis and for hypertrophy in spontaneous hypertension rats (SHRs) and to verify inhibition of the signaling pathway. Significant increases in the cardiac functional indices of left ventricular internal diameter end diastole (LVIDd) and left ventricular internal diameter end systole (LVIDs); the eccentric hypertrophy marker p-MEK5; concentric hypertrophy markers, such as CaMKII[Formula: see text] and calcineurin; and expression levels of NFATc3, p-GATA4 and BNP were observed in spontaneously hypertensive groups. PD treatment reversed these increases in SHRs. In addition, an increase in the fibrosis markers FGF2, uPA, MMP2, MMP9, TGF[Formula: see text] 1 and CTGF during cardiac hypertrophy was detected by western blotting analyses. These results demonstrated that PD treatment considerably attenuates cardiac fibrosis. Histopathological examination revealed that PD treatment remarkably reduced collagen accumulation in contrast to spontaneously hypertensive groups. This study clearly suggests that PD provides myocardial protection by alleviating two damaging responses to hypertension, fibrosis and hypertrophy, in the heart. PMID- 29595073 TI - Asatone Prevents Acute Lung Injury by Reducing Expressions of NF-[Formula: see text]B, MAPK and Inflammatory Cytokines. AB - Asatone is an active component extracted from the Chinese herb Radix et Rhizoma Asari. Our preliminary studies have indicated that asatone has an anti inflammatory effect on RAW 264.7 culture cells challenged with lipopolysaccharide (LPS). Acute lung injury (ALI) has high morbidity and mortality rates due to the onset of serious lung inflammation and edema. Whether asatone prevents ALI LPS induced requires further investigation. In vitro studies revealed that asatone at concentrations of 2.5-20[Formula: see text][Formula: see text]g/mL drastically prevented cytotoxicity and concentration-dependently reduced NO production in the LPS-challenged macrophages. In an in vivo study, the intratracheal administration of LPS increased the lung wet/dry ratio, myeloperoxidase activity, total cell counts, white blood cell counts, NO, iNOS, COX, TNF-[Formula: see text], IL 1[Formula: see text], and IL-6 in the bronchoalveolar lavage fluid as well as mitogen-activated protein kinases in the lung tissues. Pretreatment with asatone could reverse all of these effects. Asatone markedly reduced the levels of TNF [Formula: see text] and IL-6 in the lung and liver, but not in the kidney of mice. By contrast, LPS reduced anti-oxidative enzymes and inhibited NF-[Formula: see text]B activations, whereas asatone increased anti-oxidative enzymes in the bronchoalveolar lavage fluid and NF-[Formula: see text]B activations in the lung tissues. Conclusively, asatone can prevent ALI through various anti-inflammatory modalities, including the major anti-inflammatory pathways of NF-[Formula: see text]B and mitogen-activated protein kinases. These findings suggest that asatone can be applied in the treatment of ALI. PMID- 29595074 TI - Alleviation of Hippocampal Endoplasmic Reticulum Stress by Allomyrina dichotoma Larvae Extract. AB - In the brain, endoplasmic reticulum (ER) stress results in synaptic dysfunction and eventually leads to neurodegeneration. Allomyrina dichotoma larvae are a Chinese ethnomedicine and are widely used in East Asia. In the present study, we investigated the ability of ethanol extract of A. dichotoma larvae (ADE) to improve synaptic structure and function by activating unfolded protein response (UPR) under ER stress in animal and neuron culture models. ER stress was induced in obese mice fed a high fat diet (HFD) or by treating dissociated cultures of rat embryonic (E19) hippocampal neurons with tunicamycin (TM). Western blot and real-time or conventional RT-PCR were performed to analyze the expressions of ER stress marker proteins. In dissociated hippocampal cultures, immunocytochemistry was performed for synaptic proteins, and cultures were stained with styryl dye FM1-43 to assess presynaptic activities. In HFD-fed obese mice, ADE efficiently reduced the expressions of ER stress markers, such as, xbp-1, chop, atf4, erdi4, and eIf2a, and those of the ER chaperone/foldases Bip/grp78, Ero-1l, and PDI. Unconventionally spliced xbp-1s mRNA was not detected. In primary rat hippocampal cultures under ER stress, ADE significantly lowered the nuclear expression of CHOP, inhibited the downregulations of postsynaptic proteins, such as, GluN2A, GluN2B, and PSD-95, and maintained the pool size of recycling presynaptic vesicles. The study shows that ADE potently suppressed the induction of ER stress and maintained the structure and function of hippocampal neurons, and suggests that ADE is a potentially valuable food supplement and preventive therapeutic for ER stress-related nervous disorders.

AB - The prevalence of metabolic diseases has risen globally in parallel with the obesity epidemic over the past few decades. Green tea has been reported to have metabolically beneficial effects on obesity; however, the mechanism by which green tea regulates lipid metabolism is not clearly understood. Male c57BL/6 mice were fed a normal chow diet, a high-fat diet (HFD), or an HFD supplemented with various doses of epigallocatechin gallate-rich green tea extract (GTE) for 12 weeks. GTE supplementation reduced body weight gain, prevented hepatic fat accumulation, decreased hypertriglyceridemia, and improved hyperglycemia and insulin resistance in HFD-fed mice. The underlying mechanisms of these beneficial effects of GTE might involve the upregulation of sirtuin 1 and AMP activated protein kinase (AMPK) and the downregulation of enzymes related to de novo lipogenesis. Consistent with the in vivo findings, GTE increased the expression and activity of sirtuin 1, enhanced the binding of sirtuin 1 to liver kinase B1 (LKB1) and subsequent deacetylation of LKB1, and reduced triglyceride accumulation in HepG2 cells. These results suggest the possible therapeutic potential of dietary epigallocatechin gallate-rich GTE supplementation for preventing the development and progression of hepatic steatosis and obesity. PMID- 29595076 TI - Anti-Apoptotic Mechanisms of Acupuncture in Neurological Diseases: A Review. AB - Apoptosis, known as programmed cell death, plays a significant role in the pathogenesis of neurological diseases. Most of these diseases can be obviously alleviated by means of acupuncture treatment. Current research studies have shown that the efficacy of acupuncture to these medical conditions is closely associated with the anti-apoptotic potentials. Mainly based on the acupuncture's anti-apoptotic efficacy in prevalent neurological disorders, including cerebral ischemia-reperfusion injury, Alzheimer's disease, depression or stress related modes, spinal cord injuries, etc., this review comes to a conclusion that the anti-apoptotic effect of acupuncture treatment for neurological diseases, evidently reflected through Bcl-2, Bax or caspase expression change, results from regulating mitochondrial or autophagic dysfunction as well as reducing oxidative stress and inflammation. The possible mechanisms of acupuncture's anti-apoptotic effect are associated with a series of downstream signaling pathways and the up regulated expression of neurotrophic factors. It is of great importance to illuminate the exact mechanisms of acupuncture treatment for neurological dysfunctions. PMID- 29595078 TI - Symptom: Cause, Effect, Both, or Neither? PMID- 29595077 TI - Hypouricemic Effects of Armillaria mellea on Hyperuricemic Mice Regulated through OAT1 and CNT2. AB - Ethanol and water extracts of Armillaria mellea were prepared by directly soaking A. mellea in ethanol (AME) at 65[Formula: see text]C, followed by decocting the remains in water (AMW) at 85[Formula: see text]C. Significantly, AME and AMW at 30, 60 and 120[Formula: see text]mg/kg exhibited excellent hypouricemic actions, causing remarkable declines from hyperuricemic control (351[Formula: see text][Formula: see text]mol/L, [Formula: see text]) to 136, 130 and 115[Formula: see text][Formula: see text]mol/L and 250, 188 and 152[Formula: see text][Formula: see text]mol/L in serum uric acid, correspondingly. In contrast to the evident renal toxicity of allopurinol, these preparations showed little impacts. Moreover, they showed some inhibitory effect on XOD (xanthine oxidase) activity. Compared with hyperuricemic control, protein expressions of OAT1 (organic anion transporter 1) were significantly elevated in AME- and AMW-treated mice. The levels of GLUT9 (glucose transporter 9) expression were significantly decreased by AMW. CNT2 (concentrative nucleoside transporter 2), a key target for purine absorption in gastrointestinal tract was involved in this study, and was verified for its innovative role. Both AME and AMW down-regulated CNT2 proteins in the gastrointestinal tract in hyperuricemic mice. As they exhibited considerable inhibitory effects on XOD, we selected XOD as the target for virtual screening by using molecular docking, and four compounds were hit with high ranks. From the analysis, we concluded that hydrogen bond, Pi-Pi and Pi-sigma interactions might play important roles for their orientations and locations in XOD inhibition.

AB - This article describes the earliest processes involved in socializing infants into cultural beings, that are thought to set the stage for the type of interactions described in this special issue. From birth onwards, infants experience and learn whether their signals will be answered, and in what way, by whom, and when. Infants learn about their own culture from the persons around them through the meaning and interpretations these persons give to their behaviors. Many questions remain about how these processes link to infant brain development, and how insights from cultural and biological anthropology can be used to elucidate the meaning and function of sensitive caregiver-infant interactions. PMID- 29595080 TI - Characterization of integrons, extended-spectrum beta-lactamases, AmpC cephalosporinase, quinolone resistance, and molecular typing of Shigella spp. from Iran. AB - INTRODUCTION: The wide distribution of extended-spectrum beta-lactamase (ESBL) producing Shigella spp., along with the emergence of fluoroquinolone resistant isolates, is a serious threat to public health, posing a new challenge for the effective treatment of shigellosis. The purpose of this study was to determine the level of antimicrobial resistance, the presence of genes encoding resistance to cephalosporins, and plasmid-mediated quinolone resistance (PMQR) among the clinical isolates of Shigella spp. in Iran. MATERIALS AND METHODS: A total of 142 Shigella isolates were collected from different parts of Iran. All of the cephalosporin resistant Shigella strains were selected based on ESBL and AmpC production. The presence of PMQR regions was assessed in ciprofloxacin-resistant isolates, and genetic relatedness in the isolates was determined. RESULTS: Seventy-eight Shigella isolates were found to be resistant to extended-spectrum cephalosporin (ESC). The blaCTX-M15 was the most prevalent cephalosporinase. Four ESBL-producing isolates were also resistant to ciprofloxacin. Among the PMQR regions, aac(6')-lb-cr gene was the most prevalent, as it was seen in 83.3% of the ciprofloxacin resistant isolates, while qnrA was positive in 16.7%. Clonal relatedness showed a limited variety of clones was responsible for Shigella infection in the region studied. CONCLUSION: Overall, our findings indicated that a large number of ESBL producing Shigella spp. were mediated mainly by blaCTX M15. This study is the first report on ciprofloxacin-resistant ESBL-producing Shigella isolates from patients in Iran. PMID- 29595081 TI - Hip thrust-based PAP effects on sprint performance of soccer players: heavy loaded versus optimum-power development protocols. AB - This study aimed to investigate the acute effects of two barbell hip thrust-based post-activation potentiation (PAP) protocols on subsequent sprint performance. Using a crossover design, eighteen soccer athletes performed 5 m, 10 m, and 20 m sprints before and 15 s, 4 min, and 8 min after two PAP protocols. The PAP conditioning activities consisted of hip thrust exercises loaded with either 85% 1RM or a load for optimum power development. The resulting 5 m and 10 m sprint performances were impaired at 15 s following both protocols. At 4 min and 8 min, meaningful improvements were observed for the three sprint distances following both of the protocols. Meaningful differences were found when comparing the two PAPs over time: greater impairments in 5 m and 10 m following the 85% of 1 RM protocol after 15 s, and greater improvements in all sprint distances after 4 min and 8 min following the optimum power development protocol. Positive correlations between the hip thrust's 1RM and power values and the overall individual PAP responses were found. This investigation showed that both heavy-loaded and optimum-power hip thrust exercises can induce a PAP response, with the optimum power development protocol preferred due its higher efficiency.

This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9-91.7) and on grass 81.9 per 1000 match-hours (CI 72.2-92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82-1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 - 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05-4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors. PMID- 29595084 TI - A Tomato Nucleotide Binding Sites-Leucine-Rich Repeat Gene Is Positively Involved in Plant Resistance to Phytophthora infestans. AB - The nucleotide binding sites-leucine-rich repeat (NBS-LRR) genes are key regulatory components of plant to pathogens. Phytophthora infestans-inducible coding sequence encoding an NBS-LRR (SpNBS-LRR) protein in tomato (Solanum pimpinellifolium L3708) was cloned and characterized based on our RNA-Seq data and tomato genome. After sequence analysis, SpNBS-LRR was identified as a hydrophilic protein with no transmembrane topological structure and no signal peptide. SpNBS-LRR had a close genetic relationship to RPS2 of Arabidopsis thaliana by phylogenetic analysis. In addition, SpNBS-LRR gene was mainly expressed in root, with low expression observed in leaf and stem. To further investigate the role of SpNBS-LRR in tomato-P. infestans interaction, SpNBS-LRR was introduced in susceptible tomatoes and three transgenic lines with higher expression level of SpNBS-LRR were selected. These transgenic tomato plants that overexpressed SpNBS-LRR displayed greater resistance than wild-type tomato plants after infection with P. infestans, as shown by decreased disease index, lesion diameters, number of necrotic cells, P. infestans abundance, and higher expression levels of the defense-related genes. This information provides insight into SpNBS-LRR involved in the resistance of tomato to P. infestans infection and candidate for breeding to enhance biotic stress-resistance in tomato. PMID- 29595085 TI - Immunosuppressive and antiviral treatment of hepatitis C virus-associated glomerular disease: A long-term follow-up. AB - BACKGROUND: The evidence in the medical literature on the treatment of hepatitis C virus-associated glomerular disease is extremely limited. The advent of nonconventional immunosuppressive agents and direct-acting antivirals promises high efficacy and safety. AIMS: We conducted an open-label, single-arm clinical study to examine the efficacy and safety of a combined approach for hepatitis C virus-associated glomerular disease. METHODS: In the first phase of the study, patients with hepatitis C virus-associated glomerular disease received interferon based antiviral therapy and immunosuppressive agents; since 2013, interferon-free antiviral therapy was adopted and novel immunosuppressants (including B-cell depleting agents and mycophenolate mofetil) or immunomodulators (ribavirin) were choiced. Virological and clinical responses were evaluated over a long observation period (median follow-up of 60 weeks and 46.5 months after the end of treatment with interferon and direct-acting antiviral agents, respectively). RESULTS: We enrolled 25 consecutive patients with hepatitis C virus-associated glomerular disease, 8 being liver transplant recipients for hepatitis C. A total of 13 patients received therapy with direct-acting antivirals and experienced sustained viral response (serum hepatitis C virus RNA <12 IU/mL, 12 weeks after treatment ended, sustained viral response12). The mean (+/-standard deviation) proteinuria decreased from 2.61 +/- 1.01 at baseline to 1.71 +/- 1.43 (g/day) at sustained viral response 48, p = 0.031; microscopic hematuria and serum cryoglobulins disappeared in six (50%) and seven (64%) patients, respectively, after sustained viral response by direct-acting antivirals. Adverse events occurred in 69% (9/13) of patients and were mild, with four cases of ribavirin related anemia requiring blood transfusions (no drop-outs). After sustained viral response by direct-acting antivirals, immunosuppressive and immunomodulatory agents were initiated in clinical relapsers ( n = 2) and nonresponders ( n = 3) with some benefit. Among patients on interferon-based regimens ( n = 12), viral response (sustained viral response 24) and dropout rates were 58% (7/12) and 33% (4/12), respectively. After sustained viral response by interferon-based therapy, clinical relapsers ( n = 3) were successfully managed with immunosuppressive agents in two patients. CONCLUSION: Treatment with direct-acting antivirals provides excellent rates of viral response and safety in patients with hepatitis C virus-related glomerular disease; viral response was frequently accompanied by clinical improvement. The absence of hepatitis C virus RNA from serum allowed immunosuppressive and immunomodulatory therapies with benefits for glomerular abnormalities and no concern on hepatitis C virus replication. PMID- 29595086 TI - Impact of multi- versus single finger proximal interphalangeal joint arthroplasty: analysis of 249 fingers treated in 15 years. AB - : We retrospectively reviewed and compared the outcomes and complications associated with 81 single digit and 168 multi-digit proximal interphalangeal joint arthroplasties performed from 1998 to 2012 in 136 patients. Clinical outcomes were assessed with an average follow-up of 5.3 years for single digit and 5.9 years for multi-digit proximal interphalangeal joint arthroplasty. Comparing single versus multi-digit proximal interphalangeal joint arthroplasty, the reoperation-free survival was 67% and 68% at 5 years and 56% and 67% at 10 years, respectively. Furthermore, in comparison of single versus multi-digit proximal interphalangeal joint arthroplasty, the revision-free survival was 80% and 86% at 5 years and 80% and 85% at 10 years, respectively. Given the similar, or even slightly improved, rates of complications, reoperation, and revision surgery, proximal interphalangeal joint arthroplasty performed on multi-digits results in no worse outcomes compared with single digit proximal interphalangeal joint arthroplasty. LEVEL OF EVIDENCE: IV. PMID- 29595087 TI - Group B streptococci cultured in urine during pregnancy associated with preterm delivery: a selection problem? AB - OBJECTIVE: To investigate an association between Group B streptococci (GBS) in urine culture during pregnancy and preterm delivery. METHODS: A population-based cohort consisted of all the pregnant women (n = 36,097) from the catchment area of Lillebaelt Hospital, Denmark, during the period January 2002 -December 2012. The cohort of 34,285 singleton pregnancies used in this study was divided into three groups. Group I (N = 249) included women whose urine culture was positive for GBS; group II (N = 5765) included women whose urine culture was negative for GBS; and group III (N = 28 271) included women whose urine had not been cultured during pregnancy. Primary outcome was preterm delivery before 37 weeks' gestation (PTD). RESULTS: We did not find an association between PTD and GBS bacteriuria in the cultured groups (odds ratios (OR) = 0.89; 95% CI: 0.5-1.4) ( Table 1 ). After controlling for potential confounders, the PTD remained not associated with GBS bacteriuria (adjusted OR = 0.99; 95% CI: 0.6-1.6). Combined, the cultured groups (I and II) were associated with a statistically significant higher risk for PTD, when compared with the group with no urine specimens taken for culture (OR = 1.96; 95% CI: 1.8-2.2 and adjusted or 1.80; 95% CI 1.6-2.0). The cultured group of women differed considerably from the group of women with no urine specimens taken for culture on the vast majority of variables examined. CONCLUSIONS: No association between asymptomatic GBS bacteriuria and preterm delivery among women with singleton pregnancy and urine specimens cultured during pregnancy was found. Previous suggestions of such association may have been compromised by a selection problem for testing due to a high-risk profile of pregnancy complications in pregnant women selected for urine culture. PMID- 29595088 TI - The impacts of rest breaks and stretching exercises on lower back pain among commercial truck drivers in Iran. AB - PURPOSE: This study aimed to determine the impacts of rest breaks and stretching exercises on lower back pain (LBP) in commercial truck drivers. METHODS: This quasi-experiment was carried out on 92 truck drivers suffering from chronic LBP. Subjects were categorized into three groups (stretching exercises and rest breaks, rest breaks only and reference). Pain severity and related disability were measured at the beginning of the survey and after 6 and 12 weeks. The latter was assessed using the Oswestry low back pain disability questionnaire (OLBPDQ) and the Roland Morris questionnaire (RMQ). RESULTS: At the end of the intervention, the mean pain scores in the three groups were 2.72 +/- 1.44, 4.11 +/- 0.86 and 4.90 +/- 1.31 respectively (p < 0.001). The OLBPDQ scores in group 1 (stretches and resting time breaks) were significantly lower than those in group 2 (rest break) (p = 0.009). The RMQ scores showed a significant reduction in group 1 compared with the other two groups (p = 0.001). Drivers in group 2 improved more significantly than those in group 3 regarding visual analog scale pain score (p = 0.049), OLBPDQ score (p = 0.024) and RMQ score (p = 0.011). CONCLUSION: This study provided converging results that supplementary exercises during break periods consistently help to minimize LBP and disability. PMID- 29595089 TI - Mistaken identity of an open reading frame proposed for PCR-based identification of Mycoplasma bovis and the effect of polymorphisms and insertions on assay performance. AB - Mycoplasma bovis is an important cause of disease in cattle and bison. Because the bacterium requires specialized growth conditions, many diagnostic laboratories routinely use PCR to replace or complement conventional isolation and identification methods. A frequently used target of such assays is the uvrC gene, which has been shown to be highly conserved among isolates. We discovered that a previously described PCR putatively targeting the uvrC gene amplifies a fragment from an adjacent gene predicted to encode a lipoprotein. Comparison of the lipoprotein gene sequence from 211 isolates revealed several single nucleotide polymorphisms, 1 of which falls within a primer-binding sequence. Additionally, 3 isolates from this group were found to have a 1,658-bp transposase gene insertion within the amplified region that leads to a false negative result. The insertion was not detected in a further 164 isolates. We found no evidence that the nucleotide substitution within the primer-binding region affects the assay sensitivity, performance, or limit of detection. Nonetheless, laboratories utilizing this method for identification of M. bovis should be aware that the region amplified may be prone to nucleotide substitutions and/or insertions relative to the sequence used for its design and that occasional false-negative results may be obtained. PMID- 29595090 TI - A post-infection serologic assessment of cattle herd immune status after a vesicular stomatitis outbreak and the agreement of antibody assays. AB - Vesicular stomatitis (VS) is a vesicular disease of horses, cattle, and pigs in the Western Hemisphere caused by viruses in the genus Vesiculovirus. Disease manifests as vesicles and erosions on the oral mucosa, teats, prepuce, and coronary band, and is similar in presentation to foot-and-mouth disease. Laboratory confirmation is therefore required. Conventional assays include competitive (c)ELISA and complement fixation (CF). The cELISA provides more accurate herd-level detection of VSV-exposed cattle, but may lack the ability to capture fluctuating antibody levels in individual animals. The CF assay can confirm newly infected animals because of its ability to detect antigen-antibody complexes, thus is considered to be indicative of IgM. We evaluated the immune status of 2 herds affected by VSV in 2014 by testing sera collected in June 2015. Two conventional assays were compared to a novel IgM-IgG ELISA. When sampled in 2015, both herds had detectable VSV-specific antibodies; 18% and 36% of animals tested by cELISA and 2% and 8% of animals tested by CF were positive. The novel IgM-IgG assay exhibited fair agreement (adjusted kappa score of 48) with the conventional assays, and should be evaluated further to assess its ability to replace the 2 separate assays with a single assay system, or for its ability to replace the CF assay as a more sensitive method for defining newly exposed animals. PMID- 29595091 TI - Neuroprotective effect of tempeh against lipopolysaccharide-induced damage in BV 2 microglial cells. AB - OBJECTIVES: This study evaluated the bioactive composition of tempeh products and examined the effects of tempeh on BV-2 microglial cell cytotoxicity, neurotrophic effects, and expression of inflammatory genes. METHODS: Tempeh products included soybean fermented by Rhizopus, soybean fermented through cocultivation with Rhizopus and Lactobacillus, and red bean fermented through cocultivation with Rhizopus and Lactobacillus (RT-C). We analyzed the bioactive contents of tempeh extracts and evaluated the effects of tempeh water extract on lipopolysaccharide (LPS)-treated BV-2 cells. RESULTS: The results showed that RT-C water extract had the highest concentrations of gamma-aminobutyric acid (GABA) and anthocyanin. The tempeh water extracts, especially RT-C, reduced the formation of LPS-induced reactive oxygen species, downregulated the levels of nitric oxide synthase and phospho-cyclic-AMP response element-binding protein, and upregulated the expression of brain-derived neurotrophic factor (BDNF). DISCUSSION: Our data demonstrate that RT-C has the highest concentrations of GABA and anthocyanin, more effectively reduces oxidative stress and inflammation, and increases the expression of BDNF in LPS-induced BV-2 cells. PMID- 29595092 TI - Comparative safety evaluation of riot control agents of synthetic and natural origin. AB - Riot control agents (RCA) are lachrymatory, irritating compounds which temporarily incapacitate the uncontainable crowd. Ortho-Chlorobenzylidene malononitrile (CS), 2-chloroacetophenone (CN), dibenz[b,f]1:4-oxazepine (CR), and nonivamide (PAVA) are synthetic RCAs, while oleoresin extract of chili known as oleoresin capsicum (OC) a natural irritant has been in use by various law enforcement agencies. Though efficacy of these agents is beyond doubt, they suffer from certain drawbacks including toxicity, production cost, and ecological compatibility. Presently, we have evaluated the safety of CR, OC, and PAVA on inhalation variables along with oral lethality. Additionally, the liver function test (LFT) in serum and lungs function was evaluated in broncho-alveolar-lavage fluid (BALF), both collected on the 14th day after RCA exposure. Animals then sacrificed and histopathology of liver and lungs was carried out. Results showed OC and PAVA to be more toxic than CR with an oral LD50 of 150 and 200 mg/kg body weight, respectively, while CR was safe at >3 g/kg body weight. All three agents caused severe impairment of respiratory variables bringing down normal respiration by >80% with rise in sensory irritation. Recovery from the irritating effect of CR was more rapid than OC and PAVA. LFT and BALF variables were not significantly different from that of control. There were no remarkable histopathological changes in liver and lungs. Hence, as per results, CR is safest among all synthetic and natural origin RCAs and can be safely used for effective dispersion of disobedient mob. PMID- 29595093 TI - Synergy of clavine alkaloid 'chanoclavine' with tetracycline against multi-drug resistant E. coli. AB - The emergence of multi drug resistance (MDR) in Gram-negative bacteria (GNB) and lack of novel classes of antibacterial agents have raised an immediate need to identify antibacterial agents, which can reverse the phenomenon of MDR. The purpose of present study was to evaluate synergy potential and understanding the drug resistance reversal mechanism of chanoclavine isolated from Ipomoea muricata against the multi-drug-resistant clinical isolate of Escherichia coli (MDREC). Although chanoclavine did not show antibacterial activity of its own, but in combination, it could reduce the minimum inhibitory concentration (MIC) of tetracycline (TET) up to 16-folds. Chanoclavine was found to inhibit the efflux pumps which seem to be ATPase-dependent. In real-time expression analysis, chanoclavine showed down-regulation of different efflux pump genes and decreased the mutation prevention concentration of tetracycline. Further, in silico docking studies revealed significant binding affinity of chanoclavine with different proteins known to be involved in drug resistance. In in silico ADME/toxicity studies, chanoclavine was found safe with good intestinal absorption, aqueous solubility, medium blood-brain barrier (BBB), no CYP 2D6 inhibition, no hepatotoxicity, no skin irritancy, and non-mutagenic indicating towards drug likeliness of this molecule. Based on these observations, it is hypothesized that chanoclavine might be inhibiting the efflux of tetracycline from MDREC and thus enabling the more availability of tetracycline inside the cell for its action. PMID- 29595094 TI - Paediatric HIV-1 infection: updated strategies of prevention mother-to-child transmission. AB - INTRODUCTION: HIV-1 epidemiology is changing and prevention of mother-to-child transmission (PMTCT) strategies have been continuously optimized over time. However, the correct management of infected women during pregnancy is crucial for PMTCT and cases of vertical transmission continue to occur. OBJECTIVE: To review the most recent evidence regarding the prevention of MTCT in resource-rich and resource-limited settings, focalizing on new possible approaches. RESULTS: New issues regard the optimal antiretroviral therapy regimen for pregnant women with good immunological control, the use of intrapartum zidovudine (ZDV) in pregnant women with low viral load, the optimization of prophylaxis in the settings where breastfeeding is recommended and use of combined neonatal prophylaxis (CNP) in infants at high-risk for MTCT. Complete viral control, in recent years, has been achieved in most infected pregnant women, has led to change the recommended mode of delivery, since vaginal birth has become a safe option and is now largely recommended. Recent data reported a large use of CNP in preterm infants: this practice may be dangerous, due to the lack of safety data, and its efficacy and effectiveness is unproven. CONCLUSION: Data are accumulating on efficacy, effectiveness and safety of different PMTCT strategies in various possible clinical scenarios, however further researches are needed in order to optimize the management of infants at extremely low risk for MTCT as well as in those presenting with high risk for infection. PMID- 29595095 TI - Hospital networks: how to make them work in Belgium? Facilitators and barriers of different governance models. AB - Objectives This study aims to identify the facilitators and barriers to governance models of hospital collaborations. The country-specific characteristics of the Belgian healthcare system and legislation are taken into account. Methods A case study was carried out in six Belgian hospital collaborations. Different types of governance models were selected: two health systems, two participant-governed networks, and two lead-organization-governed networks. Within these collaborations, 43 people were interviewed. Results All structures have both advantages and disadvantages. It is important that the governance model fits the network. However, structural, procedural, and especially contextual factors also affect the collaborations, such as alignment of hospitals' and professionals' goals, competition, distance, level of integrated care, time needed for decision-making, and legal and financial incentives. Conclusion The fit between the governance model and the collaboration can facilitate the functioning of a collaboration. The main barriers we identified are contextual factors. The Belgian government needs to play a major role in facilitating collaboration. PMID- 29595096 TI - Modifying factors of the health belief model associated with missed clinic appointments among individuals with sickle cell disease. AB - OBJECTIVES: Outpatient care is critical in the management of chronic diseases, including sickle cell disease (SCD). Risk factors for poor adherence with clinic appointments in SCD are poorly defined. This exploratory study evaluated associations between modifying variables from the Health Belief Model and missed appointments. METHODS: We surveyed adults with SCD (n = 211) and caregivers of children with SCD (n = 331) between October 2014 and March 2016 in six centres across the U.S. The survey tool utilized the framework of the Health Belief Model, and included: social determinants, psychosocial variables, social support, health literacy and spirituality. RESULTS: A majority of adults (87%) and caregivers of children (65%) reported they missed a clinic appointment. Children (as reported by caregivers) were less likely to miss appointments than adults (OR:0.22; 95% CI:(0.13,0.39)). In adults, financial insecurity (OR:4.49; 95% CI:(1.20, 20.7)), health literacy (OR:4.64; 95% CI:(1.33, 16.15)), and age (OR:0.95; 95% CI:(0.91,0.99)) were significantly associated with missed appointments. In all participants, lower spirituality was associated with missed appointments (OR:1.83; 95%CI:(1.13, 2.94)). The most common reason for missing an appointment was forgetfulness (adults: 31%, children: 26%). A majority thought reminders would help (adults: 83%, children: 71%) using phone calls (adults: 62%, children: 61%) or text messages (adults: 56%, children: 51%). CONCLUSIONS: Our findings demonstrate that modifying components of the Health Belief Model, including age, financial security, health literacy, spirituality, and lacking cues to action like reminders, are important in missed appointments and addressing these factors could improve appointment-keeping for adults and children with SCD. PMID- 29595097 TI - The effect of nurses' empowerment perceptions on job safety behaviours: a research study in Turkey. AB - OBJECTIVE: This study aimed to investigate the effect of nurses' empowerment perceptions on job safety behaviours. METHODS: A survey of 377 nurses working in five hospitals in Turkey was conducted using the conditions of work effectiveness questionnaire, psychological empowerment instrument, universal precautions compliance scale and occupational health and safety obligations compliance scale. Relations between variables were tested using Pearson's correlation and path analysis. RESULTS: There was a moderate and statistically significant relationship between psychological and structural empowerment and complying with universal safety measures and meeting occupational health and safety obligations. Also, an increase of 1 unit on the level of psychological empowerment was found to correspond to an increase of 0.37 units on the level of universal precautions compliance and to an increase of 0.46 units on the level of occupational health and safety obligations compliance. As such, an increase of 1 unit in structural empowerment corresponds to an increase of 0.53 units on the level of universal precautions compliance and to an increase of 0.36 units (total effect) on the level of occupational health and safety obligations compliance. CONCLUSIONS: The findings reveal that empowerment is a valuable tool for nurses' positive job safety behaviours. PMID- 29595100 TI - The EU Circular Economy Package: A genius programme or an old hat? PMID- 29595099 TI - Fluidized bed combustion bottom ash: A better and alternative geo-material resource for construction. AB - Though the majority of research on fly ash has proved its worth as a construction material, the utility of bottom ash is yet questionable due to its generation during the pulverized combustion process. The bottom ash produced during the fluidized bed combustion (FBC) process is attracting more attention due to the novelty of coal combustion technology. But, to establish its suitability as construction material, it is necessary to characterize it thoroughly with respect to the geotechnical as well as mineralogical points of view. For fulfilling these objectives, the present study mainly aims at characterizing the FBC bottom ash and its comparison with pulverized coal combustion (PCC) bottom ash, collected from the same origin of coal. Suitability of FBC bottom ash as a dike filter material in contrast to PCC bottom ash in replacing traditional filter material such as sand was also studied. The suitability criteria for utilization of both bottom ash and river sand as filter material on pond ash as a base material were evaluated, and both river sand and FBC bottom ash were found to be satisfactory. The study shows that FBC bottom ash is a better geo-material than PCC bottom ash, and it could be highly recommended as an alternative suitable filter material for constructing ash dikes in place of conventional sand. PMID- 29595101 TI - Orthopedic Aspects of the Diabetic Foot. AB - BACKGROUND: Diabetes Mellitus (DM) is a common medical condition affecting more than 6% of the world population. Besides well-known pathology like diabetic retinopathy and renal insufficiency, it carries important orthopedic implications, especially around the foot and ankle (diabetic foot). Focus: This article focusses on the three major areas confronting the orthopedist: 1) changes in foot statics and biology leading to ulceration with or without osteomyelitis, 2) ankle fractures, particularly complications after a fracture and 3) Charcot foot. Their pathophysiology, clinical features, classification, diagnostic dilemmas and treatment options are discussed. CONCLUSION: DM is very common and is often associated with foot problems. Diabetic foot is a special condition that needs special attention. This article aims to provide the necessary knowledge to a better understanding and treatment of the diabetic foot. PMID- 29595102 TI - Pasireotide - Mechanism of Action and Clinical Applications. AB - BACKGROUND: Pasireotide (SOM230) is a multi-receptor ligand somatostatin analogue (SSA) developed as the successor of the first-generation SSAs. Currently, pasireotide is recommended for the treatment of patients with Cushing's disease in whom surgery was unsuccessful, and patients with acromegaly who either remain uncontrolled after surgical therapy or in whom tumor resection is not possible. METHODS AND RESULTS: Phase II and III clinical trials have shown pasireotide efficacy in these diseases, with a similar rate of adverse events when compared with first-line SSA, although higher incidence of hyperglycemia has been observed. CONCLUSION: Pasireotide therapy provides biochemical control, tumor volume reduction, and improves the quality of life in patients with those disorders. Furthermore, pasireotide might be considered as second-line therapy in patients with metastatic neuroendocrine tumors, and it also might be effective in other neoplasms with a high expression of somatostatin receptors. In addition, therapy with this novel agent has been effective in prevention of postoperative complications after pancreatectomy. However, considering the diversified responsiveness to this drug in vivo, future studies should identify factors predicting better clinical response to pasireotide. PMID- 29595103 TI - Application of Medicinal Plants as a Source for Therapeutic Agents Against Streptococcus pyogenes Infections. AB - BACKGROUND: Streptococcus pyogenes, a major human pathogen, causes a wide variety of invasive systemic infections such as acute pharyngitis, skin and soft-tissue infections, especially necrotizing fasciitis. OBJECTIVE: This review focuses on the properties of pathogenicity of S. pyogenes and outlines ways to combat infection caused by these bacteria through alternative plant-based medicine. CONCLUSION: This Gram positive bacterium has an ability to form mature biofilm and this sessile life style plays an important role in S. pyogenes pathogenicity. The virulence of these bacteria is further strengthened by its ability to communicate within the micro-colonies through quorum sensing. Most treatments are now aimed at either elimination of this bacterium or suppression of its virulence. The emergence of antibiotic resistance among S. pyogenes and treatment failure has become an added concern globally. One of its virulence properties, biofilm formation, has made it more resistant to antibiotic therapy. This has vitalized the necessity for searching alternative therapies for its treatment. The growing research in herbal medicines has led to the discovery of various phytochemicals to limit the virulence of S. pyogenes. PMID- 29595104 TI - Association of Metronidazole with Cancer: A Potential Risk Factor or Inconsistent Deductions? AB - BACKGROUND: Metronidazole (MTZ) is a synthetic derivative of nitroimidazole that has been widely used for the treatment of several bacterial and parasitic infections including trichomoniasis, amoebiasis, giardiasis, liver abscess, gingivitis, syphilis and phagedena. Scientists have evaluated its carcinogenicity in preclinical in vitro and in vivo studies. METHOD: Google scholar and Pubmed search engines were used to construct historic timeline after discovery of MTZ with a journey of ~3 decades of research. Similar search was conducted for its in vivo carcinogenic activities, further extended to elaborate its role in carcinogenicity in humans. RESULTS: In addition to preclinical in vitro validation of DNA damage, MTZ has been reported to induce cancer in a variety of animal models including lung cancer, malignant lymphomas, breast cancer, hepatocellular carcinoma, pituitary tumors, testicular neoplasms and uterine cancer. Several retrospective cohort studies have reported MTZ as a potential risk factor for lung cancer (n = 771), cervical cancer (n = 2500), breast cancer (n = 2), cholangiocarcinoma (n = 1), and neuroblastoma (n = 28). So far, all the reported data have confirmed MTZ carcinogenicity in animals; however it is still controversial in humans. Based on previous observations, the oxidative metabolites from MTZ are shown to have more carcinogenic effects than the parent drug itself. CONCLUSION: Due to potent carcinogenic behaviour, use of MTZ for animals' treatment and its uses in animal food products is prohibited in USA and European countries; however its clinical use in human population is still increasing. Therefore, regular research studies are required to explicate its mechanism/s involved in carcinogenesis. PMID- 29595105 TI - Derivation of Continuum Models from An Agent-based Cancer Model: Optimization and Sensitivity Analysis. AB - BACKGROUND: Agent-based models provide a formidable tool for exploring complex and emergent behaviour of biological systems as well as accurate results but with the drawback of needing a lot of computational power and time for subsequent analysis. On the other hand, equation-based models can more easily be used for complex analysis in a much shorter timescale. METHODS & OBJECTIVE: This paper formulates an ordinary differential equations and stochastic differential equations model to capture the behaviour of an existing agent-based model of tumour cell reprogramming and applies it to optimization of possible treatment as well as dosage sensitivity analysis. RESULTS: For certain values of the parameter space a close match between the equation-based and agent-based models is achieved. The need for division of labour between the two approaches is explored. PMID- 29595106 TI - Isolating Bacteria from Sponges: Why and How? AB - BACKGROUND: It is known that sponge-associated bacteria are an attractive source of new bioactive substances with biotechnological potential. These include antimicrobials, enzymes and surfactants. However, the potential of these microorganisms remains little investigated due to the difficulty of isolating new bacterial groups that produce original bioactive metabolites and enzymes. METHODS: Cultivation methods are still playing crucial functions in many studies involving bacteria isolated from sponges, and in the traditional approach for biodiscovery by screening culture collections. RESULTS: For instance, culture media which are rich in nutrients favor the fast cultivation in comparison with slower growing bacteria, and diluted and/or poor culture media increase the possibility of growing previously uncultured bacteria. The ability to grow bacteria in culture and to characterize their secondary metabolites is a crucial approach to new biotechnology products of potential value. Many microbial biotechnology compounds used nowadays were extracted from cultured bacteria. CONCLUSION: This review presents and discusses some strategies to isolate and culture bacteria from sponges for biotechnological exploration. Finally, whole genome sequencing of sponge-associated bacteria is proposed as a novel strategy for biodiscovery. PMID- 29595107 TI - Gene and process level modulation to overcome the bottlenecks of recombinant proteins expression in Pichia pastoris. AB - BACKGROUND: Process development involving system metabolic engineering and bioprocess engineering has become one of the major thrust for the development of therapeutic proteins or enzymes. Pichia pastoris has emerged as a prominent host for the production of therapeutic protein or enzymes. Regardless of producing high protein titers, various cellular and process level bottlenecks restrict the expression of recombinant proteins in P. pastoris. RESULT AND CONCLUSION: In the present review, we have summarized the recent developments in the expression of foreign proteins in P. pastoris. Further, we have discussed various cellular engineering strategies which include codon optimization, pathway engineering, signal peptide processing, development of protease deficient strain and glyco engineered strains for the high yield protein secretion of recombinant protein. Bioprocess development of recombinant proteins in large-scale bioreactor including medium optimization, optimum feeding strategy and co-substrate feeding in fed-batch as well as continuous cultivation have been described. The recent advances in system and synthetic biology studies including metabolic flux analysis in understanding the phenotypic characteristics of recombinant Pichia and genome editing with CRISPR-CAS system have also been summarized. PMID- 29595108 TI - Synthesis Under Microwave Irradiation And Molecular Docking Of Some Novel Bioactive Thiadiazoles. AB - A novel series of fused imidazole were prepared from reaction of 2-bromoacetyl-3 phenyl-1,3,4-thiadiazole with various heterocyclic amines under microwave irradiation. The structures of all the novel products were elucidated based on elemental analysis and spectral data. In addition, the biological activity of the newly synthesized compounds was evaluated and the results obtained indicate their potency as anti-inflammatory, analgesic and anti- ulcer agents. The binding mechanism of the most active compounds was studied using MOE to analyze the molecular interactions. PMID- 29595109 TI - Levosimendan Reduces Prostaglandin F2a-dependent Vasoconstriction in Physiological Vessels and After Experimentally Induced Subarachnoid Hemorrhage. AB - BACKGROUND: Delayed cerebral vasospasm (dCVS) following aneurysmal subarachnoid hemorrhage (aSAH) is (next to possible aneurysm rebleeding, cortical spreading depression and early brain injury) one of the main factors contributing to poor overall patient outcome. Since decades, intensive research has been ongoing with the goal of improving our understanding of the pathophysiological principles underlying dCVS. Endothelin-1 (ET-1) and prostaglandin F2 alpha (PGF2a) seem to play a major role during dCVS. The synthesis of ET-1 is enhanced after subarachnoid hemorrhage (SAH) to mediate a long-lasting vasoconstriction, and PGF2a contributes to cerebral inflammation and vasoconstriction. Under physiological conditions, levosimendan (LS) demonstrates an antagonistic effect on PGF2a-induced cerebral vasoconstriction. Thus, the intention of the present study was to analyze potentially beneficial interactions in a pathophysiological situation. METHODS: A modified double hemorrhage model was used. Functional interactions between the calcium-sensitizing action of LS and the vasoconstrictive properties of PGF2a were investigated. RESULTS: After pre incubation with LS, followed by application of PGF2a, a significant decrease in maximum contraction (Emax) for sham-operated animals was found (Emax 28% with LS, Emax 56% without LS). Using the same setting after SAH, the vessel segments did not reach a statistically significant contraction (but similar like the sham operated vessels), neither for Emax nor pD2 (-log10EC50) nor EC50 (i.e., the concentration at which half of the maximal effect occurs). LS series in sham animals were performed by pre-incubation with PGF2a. The resultant Emax showed a statistically strong significance concerning a higher vasorelaxation compared with a solvent control group. Vessel segment relaxation was significantly stronger in the same experimental setup after SAH. CONCLUSION: Under physiological and pathophysiological circumstances, LS reduced and dosedependently reversed PGF2a-induced vasoconstriction. These results can be applied to further developing methods to antagonize dCVS after aSAH. PMID- 29595110 TI - Coumarin Compounds in Medicinal Chemistry: Some Important Examples from the Last Years. AB - Coumarins are natural products characterized as 1,2 benzopyrones widely distributed in plants, as well as, in many species of fungi and bacteria. Nowadays, many synthetic procedures allow the discovery of coumarins with expanded chemical space. The ability to exert noncovalent interactions with many enzymes and receptors in live organisms lead the coumarins to exhibit a wide range of biological activities and applications. Then, this manuscript provides an overview of the use of coumarins compounds in medicinal chemistry in treating many diseases. Important examples of the last years have been selected concerning the activities of coumarins as anticoagulant, anticancer, antioxidant, antiviral, anti-diabetics, anti-inflammatory, antibacterial, antifungal and anti neurodegerative agents. Additionally, it also includes applications of coumarins as fluorescent sensors for biological systems. Thus, this work aims to contribute to the development of new rational research projects for the treatment and diagnosis of pathologies using coumarin derivatives. PMID- 29595111 TI - Looking for New Inhibitors for the Epidermal Growth Factor Receptor. AB - Epidermal Growth Factor Receptor (EGFR) is still the main target of the Head and Neck Squamous Cell Cancer (HNSCC) because its overexpression has been detected in more than 90% of this type of cancer. This overexpression is usually linked with more aggressive disease, increased resistance to chemotherapy and radiotherapy, increased metastasis, inhibition of apoptosis, promotion of neoplastic angiogenesis, and, finally, poor prognosis and decreased survival. Due to this reason, the main target in the search of new drugs and inhibitors candidates is to downturn this overexpression. Quantitative Structure-Activity Relationship (QSAR) is one of the most widely used approaches while looking for new and more active inhibitors drugs. In this contest, a lot of authors used this technique, combined with others, to find new drugs or enhance the activity of well-known inhibitors. In this paper, on one hand, we will review the most important QSAR approaches developed in the last fifteen years, spacing from classical 1D approaches until more sophisticated 3D; the first paper is dated 2003 while the last one is from 2017. On the other hand, we will present a completely new QSAR approach aimed at the prediction of new EGFR inhibitors drugs. The model presented here has been developed over a dataset consisting of more than 1000 compounds using various molecular descriptors calculated with the DRAGON 7.0(c) software. PMID- 29595112 TI - Synthesis and Biological Evaluation of Coumarins Derivatives as Potential Inhibitors of the Production of Pseudomonas aeruginosa Virulence Factor Pyocyanin. AB - Antimicrobial Resistance (AMR) is a serious problem for the humans since it threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi. One way around this problem is to act on the virulence factors, produced by bacteria, which increase their infection effectiveness. In view of these facts, new coumarin derivatives were synthesized and evaluated for their anti-virulence biological activity towards Pseudomonas aeruginosa. The results suggest that coumarin derivatives with a secondary carbon at C-3 position reduces P. aeruginosa growth whereas compounds with one additional substituent have a significant effect over pyocyanin production (10k EC50 7 +/- 2 uM; 10l EC50 42 +/- 13 uM). Moreover, 10k reduces P. aeruginosa motility and biofilm formation, what is compatible with a quorum sensing related mechanism of action. PMID- 29595113 TI - Impact of Primary Tumor Location on First-line Bevacizumab or Cetuximab in Metastatic Colorectal Cancer. AB - BACKGROUND: Colorectal cancer is one of the most common malignancies in the United States, with a large proportion of patients presenting with metastatic disease or developing a recurrence. Systemic chemotherapy is the mainstay of therapy in this setting. There is a clear benefit in the addition of bevacizumab or cetuximab (for rat sarcoma [RAS] wild type tumors) to oxaliplatin- and irinotecan-based regimens which can be considered for first-line therapy. However, many significant questions remain as to which agent reflects best practice. OBJECTIVE: Our review aimed to elucidate the benefit of adding bevacizumab and cetuximab to initial therapy for metastatic colorectal cancer based on primary tumor location and a variety of other disease- and patient related factors, addressing the paucity of evidence that currently exists in this area and contributing to current literature and clinical practices. METHODS: The primary endpoints of the study were first Progression-Free Survival (PFS) and Overall Survival (OS). Secondary endpoints included best response to first- and second-line therapies, Treatment- Related Adverse Events (TRAEs), second PFS, cost of therapy, and an assessment of other patient- and disease-related factors affecting PFS and OS. RESULTS: While there were trends towards improved OS in patients with left-sided primary tumors (n=57) compared to those with right-sided disease (n=23), there were no significant differences between the two groups in either primary endpoint. While no differences were found for patients with left- or right- sided tumors stratified by add-on agent, these analyses were limited by the small number of patients receiving cetuximab with first-line therapy (n=4). However, the bevacizumab cohort (n=76) was sizable enough to provide ample data and produce clinically relevant results. Add-on therapy with bevacizumab in our study achieved impressive survival outcomes in both left-sided (median first PFS = 13 months, 95% CI 11-15 months; median OS = 37 months, 95% CI 21-53 months) and right-sided (median first PFS = 13 months, 95% CI 9-17 months; median OS = 37 months, 95% CI 22-52 months) disease. CONCLUSION: These results raised questions regarding the true significance of primary tumor location when selecting bevacizumab or cetuximab for first-line therapy, particularly the current thought of using cetuximab for left-sided tumors. While the superiority of bevacizumab over cetuximab in rightsided disease remained evident upon comparison of our analysis with historical controls, survival outcomes with the agent in our analysis appeared to be similar to that of cetuximab in CRYSTAL, FIRE- 3, and CALGB/SWOG 80405 in left-sided disease. Further study is required to determine if bevacizumab truly does produce similar outcomes to cetuximab in left-sided primary tumors. PMID- 29595114 TI - Some Thiazole Derivatives Combined With Different Heterocycles : Cytotoxicity Evaluation And Apoptosis Inducing Studies. AB - BACKGROUND: Thiazole ring is an outstanding structure found in many biologically active compounds and clinically available drugs. Because of synthesis simplicity of its derivatives and having a wide range of biological aspects along with high effectiveness, new thiazole derivatives have been studied by medicinal chemists since many years. OBJECTIVE: Therefrom some thiazole compounds combined with different heterocyclic rings were acquired in this study. Novel 5-(4-substituted benzylidene)-2-[(4,5-dimethylthiazol-2-yl)amino]thiazol-4(5H)-one derivatives (4a g) and 2-(heteroaryl-2/3/5-yl)thio-N-(4,5-dimethylthiazol-2-yl)acetamide (4h-p) derivatives were synthesized starting from 2-amino-4,5-dimethylthiazole. The obtained compounds were evaluated to determine their antiproliferative activity. METHOD: Final compounds (4a-g) were obtained with ring closure reaction; other final compounds (4h-p) were acquired via the reaction of mercapto heterocycles with Hantzsch thiazole synthesis intermediate. To evaluate antiproliferative activity of them, compounds were tested on A549 adenocarcinomic human alveolar basal epithelial cells line, C6 rat glioma cell line and NIH/3T3 mouse embryo fibroblast cell line according to conventional MTT method. Besides, selected compounds were studied to find out which pathway cell deaths caused from via Annexin V/PI staining. RESULTS: Compounds 4f, 4j and 4p exhibited the highest cytotoxicity on A549 with a non-toxic profile. Also, 4f, 4h, 4j and 4p were determined as the most antiproliferative compounds on C6 cell line. Furthermore, compound 4p induced apoptosis of A549 cell with a level of 23.5% and compound 4h induced C6 cell with a level of 37.5%. CONCLUSION: Considering the structure of the compounds, although thiazolidine containing compounds 4a-g exhibited higher activity in general, compounds 4p containing 5-chlorobenzothiazole moiety showed the highest cytotoxicity. It could be expressed with conspicuous antitumor efficiency of benzothiazole ring. PMID- 29595115 TI - Efficacy and Non Invasive Treatment of Sialorrhea in the Goldenhar Syndrome. AB - BACKGROUND AND OBJECTIVE: Goldenhar syndrome (ocular-auricular-vertebral syndrome), a rare congenital condition arising from defects in the first and second brachial arches, consists in clinical variety of features ranging from facial abnormalities, ear-eye abnormalities, vertebral defects and congenital heart problems and severe obstructive sleep apnea. Due to craniofacial abnormalities, patients presents mechanical obstructive phenomena and sialorrhea that cause prone position, language's fastening, use of nasopharyngeal cannulas and tracheal intubation. METHODS: In this article, we report a case of a 16 years old child affected by Goldenhar syndrome and sialorrhea to demonstrate improvement of the daily patient management, through inoculations of botulinum toxin type A. Due to severe sialorrhea which caused tracheobronchial daily aspirations, the caregivers used an external aspirators. RESULTS: In the first infiltration (August 2016) the parotid and submandibular glands bilaterally were inoculated with incobotulinum toxin type A (Xeomin(r), Merz Pharma) with dosages of 5 UI for each of them, for a total of 20 UI without clinical efficacy (no quantitative and qualitative saliva reducing during 3 months). In the second (November 2016) and third (February 2017) infiltrations each parotid and each submandibular glands were injected with a (dosage of 7 UI and 5 UI respectively (total of 24 UI of incobotulinumtoxin A) with important clinical results (saliva production and tracheo-bronchial aspirations reduced). CONCLUSION: Therefore, botulinum toxin type A could be a good and non invasive treatment of sialorrhea in Goldenhar syndrome to improve oral hygiene and daily patient management. PMID- 29595116 TI - Ameliorative Potentials of Methanol Fractions of Cnidoscolus aconitifolius on Some Hematological and Biochemical Parameters in Streptozotocin Diabetic Rats. AB - BACKGROUND: There is a paucity of information in the literature on the effect of Cnidoscolus aconitifolius on the hematological, coagulation activities, electrolyte balance and antioxidant activities of humans or animals. OBJECTIVES: To determine the ameliorative potentials of methanol fractions of Cnidoscolus aconitifolius on hematological, coagulation, electrolyte, hepatic and renal antioxidant activities of streptozotocininduced diabetic rats using standard techniques. METHOD: Thirty rats, distributed into five groups of six rats each were used for this study. Groups 1 and 2 (normal and diabetic controls) received 1 ml/kg normal saline. Groups 3 and 4 received methanol fractions of Cnidoscolus aconitifolius (at 250 and 500 mg/kg). Group 5 was administered glibenclamide (2.5 mg/kg). RESULTS: The diabetic control had decreased (P<0.05) white blood cells, red blood cells, hemoglobin, packed cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, lymphocytes, eosinophils, thrombin time, prothrombin time, activated partial thromboplastin time, sodium, potassium, bicarbonate ions, hepatic and renal superoxide dismutase, catalase and glutathione peroxidase activities; increased (P<0.05) neutrophils, fibrinogen and platelets counts, chloride ion levels compared with the normal control while their monocytes were not different (P>0.05) from that of the normal control. Basophils were not detected in all the groups that were studied. The methanol fraction at 500 mg/kg was more potent than the methanol fraction at 250 mg/kg or glibenclamide (at 2.5 mg/kg) in ameliorating the hematological parameters, serum electrolytes and oxidative stress in the hepatic and kidney tissues of the diabetic rats suggesting its potentials in the management of diabetic complications. CONCLUSION: Finally, the biological properties demonstrated by the methanol fraction could be attributed to the presence of octadecanoic acid, n-hexadecanoic acid, eicosanoic acid, tetradecanoic acid and n-hexadecanoic acid in it as previously reported. PMID- 29595117 TI - Non-Alcoholic Fatty Pancreas Disease (NAFPD): A Silent Spectator or the Fifth Component of Metabolic Syndrome? A Literature Review. AB - BACKGROUND AND OBJECTIVE: Fat accumulation in the pancreas has remained a relatively unknown disease since it was initially described in 1926. However, it has gained increasing attention in the past two decades with the emergence of the obesity epidemic. Pancreatic steatosis is a general term used for fat accumulation in the pancreas. It is further classified into fatty replacement, fatty infiltration, lipomatous pseudo-hypertrophy, non-alcoholic fatty pancreas disease (NAFPD) and non-alcoholic fatty steatopancreatitis (NASP). NAFPD is defined as obesity-associated accumulation of fat in the pancreas without significant alcohol consumption. Data on the prevalence of NAFPD are limited due to a lack of standardized screening tests. METHODS: MEDLINE/PubMed was searched to find relevant studies and abstracts on pancreatic steatosis. RESULTS: Pancreatic fat can be quantified by various imaging techniques including ultrasonography, computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy. The pathophysiology of NAFPD has not been completely understood. Chronic exposure of beta-cells to hyperglycemia and higher levels of free fatty acids results in increased intracellular triglyceride accumulation, which ultimately causes reduced insulin secretion, insulin resistance, cell apoptosis and subsequent fatty replacement. This vicious cycle likely is a determining factor in the development of diabetes mellitus and metabolic syndrome. There is no approved pharmacologic therapy for NAFPD. Caloric restriction might have a role in normalization of beta-cell function by reducing pancreatic fat content. Troglitazone (blend of telmisartan and sitagliptin) has demonstrated effectiveness in animal models but is still in experimental stages. CONCLUSION: The cause and effect relationship between the metabolic syndrome and NAFPD has not yet been established. Further studies are required to study the effect of NAFPD on glucose hemostasis. PMID- 29595118 TI - Evaluation of the Antidiabetic Property of Capparis Ovata Desf. Var. Palaestina Zoh. Extracts Using In vivo and In vitro Approaches. AB - BACKGROUND AND OBJECTIVE: This paper is focused on evaluating the various biological activities of C. ovata var. palaestina extracts which could beneficially influence diabetes and its complications. METHODS: Alloxan-induced diabetic BALB-c mice were administered intraperitoneally with 100, 300, 500mg/kg doses of ethanol and aqueous extracts of buds and fruits. Furthermore, HPLC, phenolic and flavonoid compounds analysis, ABTS and DPPH free radical scavenging activity, anti-inflammatory activity, agar well diffusion and MIC tests were carried out. RESULTS: Fruit-aqueous; 100mg/kg, 300mg/kg and bud-aqueous; 500mg/kg extracts showed significant hypoglycemic activity. All extracts indicated important antioxidant activity, however, bud-aqueous extract demonstrated the most potent activity. HPLC study exhibited that rutin is found in high amounts in bud-aqueous and bud-ethanol extracts. Furthermore, the bud-aqueous extract depicted stronger and broader antimicrobial activity than other extracts. Fruit ethanol and bud-ethanol extracts denoted the most potent anti-inflammatory effect even though this effect was significantly shown by all extracts. Finally, high levels of phenolic and flavonoid content were involved in all extracts, but the highest levels were found in fruit-ethanol and bud-ethanol extracts. CONCLUSION: The results showed that extracts which indicated hypoglycemic, antioxidant, antiinflammatory, antimicrobial activities may provide a valuable contribution to the management of diabetes and its complications. PMID- 29595119 TI - Cytochrome P450 3A4 Induction: Lumacaftor versus Ivacaftor Potentially Resulting in Significantly Reduced Plasma Concentration of Ivacaftor. AB - BACKGROUND & OBJECTIVE: Since the release of ivacaftor-lumacaftor, several red flags have been raised that highlight the clinical efficacy of this combination strategy that may be limited due to antagonistic drug-drug interactions. METHOD: The effect of ivacaftor, its major metabolites M1 and M6, lumacaftor and the novel cystic fibrosis transmembrane conductance regulator (CFTR) modulator tezacaftor at 10 ug/mL on the enzymatic activity of the major xenobiotic metabolizing enzymes CYP1A2 and CYP3A4 as well as the minor enzymes CYP2B6 and CYP2C9 was assayed. RESULTS: Lumacaftor (3.74 x 105 +/- 3.11 x 104 RLU), and ivacaftor-M6 (3.43 x 105 +/- 7.61 x 103 RLU) markedly induced the activity of CYP3A4. Ivacaftor (2.22 x 105 +/- 3.94 x 104 RLU) showed a lower relative ratio of luminescence units compared to chloramphenicol (3.17 x 105 +/- 1.55 x 104 RLU). Interestingly, ivacaftor-M1 (6.74 x 104 +/- 3.09 x 104 RLU) and the novel CFTR modulator tezacaftor (2.40 x 104 +/- 8.14 x 104 RLU) did not show CYP3A4 induction. In the CYP1A2 and CYP2C9 assay, all metabolites showed a decrease in the ratio of luminescence units compared to the controls. Ivacaftor, its major metabolites, lumacaftor and tezacaftor all showed a slight increase in the ratio of luminescence units compared to the control rifampin with CYP2B6. CONCLUSION: All in all, present findings would suggest that lumacaftor and ivacaftor-M6 are strong inducers of CYP3A4, potentially reducing ivacaftor concentrations; ivacaftor itself induces CYP3A4 to some extent. PMID- 29595120 TI - State-of-the-Art on Viral microRNAs in HPV Infection and Cancer Development. AB - BACKGROUND: High-risk HPV subtypes are driving forces for human cancer development: HPV-16 and HPV-18 are responsible for most HPV-caused cancers. OBJECTIVE: This review describes the present knowledge on HR-HPV genomes coding potential for viral miRNAs. METHODS: HPV subtypes miRNA database, VIRmiRtar, has been constructed applying bioinformatics and a computational method, ViralMir, exploiting structural features, the presence of hairpins, and validation by comparison with RNA sequencing datasets. RESULTS: Several miRNA candidates have been localised in the genomes of high-risk HPV subtypes. Among these, HPV-16 miR 1, miR-2 and miR-3. The database contains a list of host candidate gene targets that may be responsible for the oncogenesis in the various cellular environments. CONCLUSION: miRNA silencing therapies, based on specific cellular uptake of miRNA mimics and antagomiRs, directed towards HPV encoded miRNAs and/or microRNAs deregulated in the host cells, could be a valuable approach to support pharmaceutical interventions in the treatment of HPV dependent cancers. PMID- 29595121 TI - The Expansion Segments of Human 28S rRNA Match MicroRNAs Much Above 18S rRNA or Core Segments. AB - BACKGROUND: The size of eukaryotic 25-28S rRNAs shows a progressive phylogenetically linked increase which is pronounced in mammals, and especially in hominids. The increase is confined to specific expansion segments, inserted at points that are highly conserved from yeast to man. These segments also show a progressive increase in nucleotide bias, mostly the GC bias. Substantial parts of the large expansion segments 7, 15 and 27 of 28S rRNA are known to be exposed at the ribosome surface, with no clear association with ribosomal proteins. These segments could bind extraneous RNAs and proteins to support regulatory events. METHODS: This study examined the possible canonical matching of human 28S rRNA and 18S rRNA segments with 2586 human microRNAs. This was compared with matching of the microRNAs to sectors of 18810 human mRNAs. RESULTS: The overall matching was rather similar across 18S rRNA segments and core segments of 28S rRNA. However, the expansion segments of 28S rRNA (abbreviated ESL) collectively have a much higher (up to two-fold) capacity for the canonical association with microRNAs. This is pronounced in large ESL, and is found to strongly relate to the GC content of microRNAs. CONCLUSION: Oligonucleotides and microRNAs of high GC content through a strong canonical hydrogen bonding could have large activity in regulation of subcellular RNAs. In view of the considerable abundance of ribosomal RNAs in many mammalian tissues, ESL could constitute an important component of microRNA balance, possibly serving to lower the availability of GC rich microRNAs (and thereby help conservation of GC-rich mRNAs).

AB - OBJECTIVE: This study was designed to clarify the factors affecting the efficacy, adverse events, and pharmacokinetics of fondaparinux in Japanese patients undergoing artificial knee replacement surgery. MATERIALS AND METHODS: Fondaparinux (1.5 mg/d) was administered subcutaneously to patients (n = 30) at 24 hours after surgery, and blood samples were taken at various time points thereafter. Venous thromboembolism (VTE), presence of bleeding, and pharmacokinetics were evaluated. Multivariate analysis and population pharmacokinetic analysis were performed to detect factors that necessitated withdrawal of fondaparinux and individual differences in its pharmacokinetics. RESULTS: VTE was observed in 9 patients (3 for whom administration was continued and 6 for whom withdrawal was necessary). The maximum plasma concentration of fondaparinux was found to be a significant factor determining withdrawal of the drug. Population pharmacokinetic analysis demonstrated that individual renal function and body weight were significant factors associated with apparent clearance and volume of distribution, respectively. CONCLUSIONS: A high maximum plasma concentration of fondaparinux may result in subcutaneous hemorrhage, necessitating withdrawal of fondaparinux administration. The patient's kidney function and body weight also contribute to individual differences in pharmacokinetics. We recommend considering an adjustment to the dose of fondaparinux based on body weight in patients undergoing artificial knee replacement surgery.?. PMID- 29595123 TI - Investigation of a potential drug-drug interaction between salbutamol and ambroxol and bioequivalence of a new fixed-dose combination containing these two drugs in healthy Chinese subjects. AB - OBJECTIVES: The aims of the study were to investigate the potential drug-drug interaction between salbutamol and ambroxol, the bioequivalence of the new fixed dose combination containing salbutamol and ambroxol compared with co administration of the two separate formulations, and to describe the safety and tolerability of the fixed-dose combination formulation in healthy Chinese volunteers. MATERIALS AND METHODS: An open-label, single-dose, four-treatment, four-period crossover study for evaluation of drug-drug interaction and bioequivalence (n = 24) was performed. Each participant received salbutamol 4 mg, ambroxol 15 mg, salbutamol 4 mg co-administered with ambroxol 15 mg or fixed-dose combination formulation (salbutamol 4 mg and ambroxol 15 mg). Plasma concentrations of two analytes were determined with the use of validated LC-MS/MS method. Safety and tolerability were assessed by recording adverse events. RESULTS: Co-administration of salbutamol and ambroxol was not associated with a significant influence on single salbutamol or ambroxol pharmacokinetics. After statistical comparisons of log-transformed Cmax and AUC of salbutamol and ambroxol between fixed-dose combination and concomitant treatments, all 90% confidence intervals of geometric mean ratios were within the predefined equivalence range of 80 - 125%. No serious adverse events were reported, and all treatments were safe and well tolerated in Chinese healthy subjects. CONCLUSION: There were no significant drug-drug pharmacokinetic interactions between salbutamol and ambroxol after oral administration. The new formulation was bioequivalent to the co-administration of two drugs in separate dosage forms.?. PMID- 29595124 TI - Absence of 1p/19q codeletion in oligodendroglioma-like areas of pilocytic astrocytomas. AB - The presence of oligodendroglioma-like areas in pilocytic astrocytoma may give rise to pathologic diagnostic uncertainty. This study aims to determine if the oligodendroglioma-like areas present in some pilocytic astrocytomas (PA) possess the signature 1p/19q codeletion that is characteristic of classical oligodendroglioma. Array comparative genomic hybridization was carried out on 12 PA samples, from which oligodendroglioma-like areas were microdissected and used as the template DNA source. 1p/19q codeletions were not found in any of the oligodendroglioma areas in PAs. We conclude that PAs with oligodendroglioma-like areas do not share the same molecular genetics as classic oligodendroglioma.?. PMID- 29595125 TI - A 3-year old female with an atypical pineal tumor.

PMID- 29595129 TI - Assessing the validity of surrogate endpoints in the context of a controversy about the measurement of effectiveness of hepatitis C virus treatment. AB - Surrogate endpoints are often used in clinical trials, as they allow for indirect measures of outcomes (eg, shorter trials with less participants). Improvements in surrogate endpoints (eg, reduction in low density lipoprotein cholesterol, normalisation of glycated haemoglobin) achieved with an intervention are, however, not always associated with improvements in patient-important outcomes. The common tendency in evidence-based medicine is to view results based on surrogate endpoints as less certain than results based on long term, final patient-important outcomes and rate them as 'lower quality evidence'. However, careful appraisal of the validity of a surrogate endpoint as a measure of the final, patient-important outcome is more useful than an automatic judgement. In this guide, we use a contemporary and currently highly debated example of the surrogate endpoint 'sustained viral response' (ie, viral eradication considered to represent successful treatment) in patients treated for chronic hepatitis C virus. We demonstrate how the validity of a surrogate endpoint can be critically appraised to assess the quality of the evidence (ie, the certainty in estimates) and the implications for decision-making. PMID- 29595130 TI - Verification bias. AB - This article is part of the Catalogue of Bias series. We present a description of verification bias, and outline its potential impact on research studies and the preventive steps to minimise its risk. We also present teaching slides in the online supplementary file. Verification bias (sometimes referred to as 'work-up bias') concerns the test(s) used to confirm a diagnosis within a diagnostic accuracy study. Verification bias occurs when only a proportion of the study participants receive confirmation of the diagnosis by the reference standard test, or if some participants receive a different reference standard test.

PMID- 29595132 TI - Synergistic effects of blood pressure-lowering drugs and statins: systematic review and meta-analysis. AB - BACKGROUND: Synergistic effects of blood pressure-lowering drugs and statins are unknown, but are key to risk-based treatment decision strategies and fixed combination polypills. OBJECTIVE: We conducted a systematic literature review and meta-analysis to test the hypothesis that the combined relative effects of blood pressure-lowering drugs and statins on cardiovascular outcomes are multiplicative. STUDY SELECTION: Two persons independently searched five data sources and hand-searched reference lists from earliest available to December 2017. We included factorial trials with at least two randomised interventions including one statin versus placebo factor and one blood pressure-lowering drug/more intense blood pressure-lowering regimen versus placebo/less intense regimen factor, and reported cardiovascular events or mortality as outcomes. We tested interactions as departures from additivity or multiplicativity using mixed effects logistic regression models. FINDINGS: Seven out of 1017 screened studies fulfilled the selection criteria, contributing a total of 27 020 patients with 857 major cardiovascular events and 725 deaths. The relative risk reduction of major cardiovascular events with active/more intense blood pressure-lowering regimen was not materially different in subgroups randomised to statins (risk ratio 0.81, 95% CI 0.66 to 1.00) or placebo (0.94, 0.79 to 1.11). Likewise, statin effects were not substantially different in subgroups randomised to active/more intense blood pressure-lowering regimen (0.69, 0.57 to 0.85) or placebo/less intense regimen (0.80, 0.67 to 0.96). No departures from either additivity or multiplicativity were observed. Heterogeneity was low. CONCLUSIONS: The combined relative effects of blood pressure-lowering drugs and statins on cardiovascular events were multiplicative. This supports risk-based treatment decision strategies and fixed-combination polypills.

AB - The partnership between coral and its algal symbionts, Symbiodinium, is crucial to the global environment. Yet, the regulatory process within the photosynthetic machinery of Symbiodinium is still not clearly understood. Here, we studied the influence of light stress from focussed red and blue lasers on single Symbiodinium cells. Fluorescence signals were measured to show cell response. Increasing the incident laser power or the exposure time resulted in an increase followed by a decline in fluorescence intensity. The trend of fluorescence intensity changes was associated with mechanisms of light use efficiency, non photochemical quenching, photoinhibition, and repair of the cell. Our study provides new approaches to studying the photobiology and physiology of Symbiodinium cells. PMID- 29595144 TI - Photoemission perspective on pseudogap, superconducting fluctuations, and charge order in cuprates: a review of recent progress. AB - In the course of seeking the microscopic mechanism of superconductivity in cuprate high temperature superconductors, the pseudogap phase- the very abnormal 'normal' state on the hole-doped side- has proven to be as big of a quandary as superconductivity itself. Angle-resolved photoemission spectroscopy (ARPES) is a powerful tool for assessing the momentum-dependent phenomenology of the pseudogap, and recent technological developments have permitted a more detailed understanding. This report reviews recent progress in understanding the relationship between superconductivity and the pseudogap, the Fermi arc phenomena, and the relationship between charge order and pseudogap from the perspective of ARPES measurements. PMID- 29595143 TI - Matrix stiffness and tumor-associated macrophages modulate epithelial to mesenchymal transition of human adenocarcinoma cells. AB - The tumor microenvironment (TME) is gaining increasing attention in oncology, as it is recognized to be functionally important during tumor development and progression. Tumors are heterogeneous tissues that, in addition to tumor cells, contain tumor-associated cell types such as immune cells, fibroblasts, and endothelial cells. These other cells, together with the specific extracellular matrix (ECM), create a permissive environment for tumor growth. While the influence of tumor-infiltrating cells and mechanical properties of the ECM in tumor invasion and progression have been studied separately, their interaction within the complex TME and the epithelial -to-mesenchymal transition (EMT) is still unclear. In this work, we develop a 3D co-culture model of lung adenocarcinoma cells and macrophages in an interpenetrating network hydrogel, to investigate the influence of the macrophage phenotype and ECM stiffness in the induction of EMT. Rising ECM stiffness increases both tumor cell proliferation and invasiveness. The presence of tumor-associated macrophages and the ECM stiffness jointly contribute to an invasive phenotype, and modulate the expression of key EMT-related markers. Overall, these findings support the utility of in vitro 3D cancer models that allow one to study interactions among key components of the TME. PMID- 29595145 TI - Feasibility of online IMPT adaptation using fast, automatic and robust dose restoration. AB - Intensity-modulated proton therapy (IMPT) offers excellent dose conformity and healthy tissue sparing, but it can be substantially compromised in the presence of anatomical changes. A major dosimetric effect is caused by density changes, which alter the planned proton range in the patient. Three different methods, which automatically restore an IMPT plan dose on a daily CT image were implemented and compared: (1) simple dose restoration (DR) using optimization objectives of the initial plan, (2) voxel-wise dose restoration (vDR), and (3) isodose volume dose restoration (iDR). Dose restorations were calculated for three different clinical cases, selected to test different capabilities of the restoration methods: large range adaptation, complex dose distributions and robust re-optimization. All dose restorations were obtained in less than 5 min, without manual adjustments of the optimization settings. The evaluation of initial plans on repeated CTs showed large dose distortions, which were substantially reduced after restoration. In general, all dose restoration methods improved DVH-based scores in propagated target volumes and OARs. Analysis of local dose differences showed that, although all dose restorations performed similarly in high dose regions, iDR restored the initial dose with higher precision and accuracy in the whole patient anatomy. Median dose errors decreased from 13.55 Gy in distorted plan to 9.75 Gy (vDR), 6.2 Gy (DR) and 4.3 Gy (iDR). High quality dose restoration is essential to minimize or eventually by-pass the physician approval of the restored plan, as long as dose stability can be assumed. Motion (as well as setup and range uncertainties) can be taken into account by including robust optimization in the dose restoration. Restoring clinically-approved dose distribution on repeated CTs does not require new ROI segmentation and is compatible with an online adaptive workflow. PMID- 29595146 TI - Assessment of linear and nonlinear/complex heartbeat dynamics in subclinical depression (dysphoria). AB - OBJECTIVE: Depression is one of the leading causes of disability worldwide. Most previous studies have focused on major depression, and studies on subclinical depression, such as those on so-called dysphoria, have been overlooked. Indeed, dysphoria is associated with a high prevalence of somatic disorders, and a reduction of quality of life and life expectancy. In current clinical practice, dysphoria is assessed using psychometric questionnaires and structured interviews only, without taking into account objective pathophysiological indices. To address this problem, in this study we investigated heartbeat linear and nonlinear dynamics to derive objective autonomic nervous system biomarkers of dysphoria. APPROACH: Sixty undergraduate students participated in the study: according to clinical evaluation, 24 of them were dysphoric. Extensive group-wise statistics was performed to characterize the pathological and control groups. Moreover, a recursive feature elimination algorithm based on a K-NN classifier was carried out for the automatic recognition of dysphoria at a single-subject level. MAIN RESULTS: The results showed that the most significant group-wise differences referred to increased heartbeat complexity (particularly for fractal dimension, sample entropy and recurrence plot analysis) with regards to the healthy controls, confirming dysfunctional nonlinear sympatho-vagal dynamics in mood disorders. Furthermore, a balanced accuracy of 79.17% was achieved in automatically distinguishing dysphoric patients from controls, with the most informative power attributed to nonlinear, spectral and polyspectral quantifiers of cardiovascular variability. SIGNIFICANCE: This study experimentally supports the assessment of dysphoria as a defined clinical condition with specific characteristics which are different both from healthy, fully euthymic controls and from full-blown major depression. PMID- 29595147 TI - Measuring the effective area and charge density of platinum electrodes for bionic devices. AB - OBJECTIVE: Neural stimulation is usually performed with fairly large platinum electrodes. Smaller electrodes increase the applied charge density, potentially damaging the electrode. Greater understanding of the charge injection mechanism is required for safe neural stimulation. APPROACH: The charge injection mechanism and charge injection capacity were measured by cyclic voltammetry. Electrodes were cleaned mechanically or by potential cycling in acidic solutions. The effective electrode area was measured by hydrogen adsorption or reduction of [Formula: see text]. MAIN RESULTS: The water window and safe potential window were affected by changes to electrolyte, electrode size, polishing method and oxygen concentration. Capacitance and Faradaic current contribute to the charge injection capacity. Varying voltammetric scan rate (measurement time), electrode size, polishing method, potential window, electrolyte and oxygen concentration affected the charge injection capacity and ratio of oxidation to reduction charge. Hydrogen adsorption in acidic solutions provided an inaccurate effective electrode area. Reduction of a solution phase redox species with a linear or radial diffusion profile could provide an effective electrode area. The charge density (charge injection capacity divided by electrode area) of a platinum electrode is dependent on the charge injection capacity and electrode area measurement technique. By varying cyclic voltammetric conditions, the charge density of platinum ranged from 0.15 to 5.57 mC cm-2. SIGNIFICANCE: The safe potential window, charge injection mechanism, charge injection capacity and charge density of platinum depends on electrolyte, size of the electrode, oxygen concentration and differences in electrode polishing method. The oxidation and reduction charge injection capacities are not equal. Careful control of a platinum electrodes surface may allow larger charge densities and safe use of smaller electrodes. New electrode materials and geometries should be tested in a consistent manner to allow comparison of potential suitability for neural stimulation. PMID- 29595148 TI - Colloidal lithography nanostructured Pd/PdO x core-shell sensor for ppb level H2S detection. AB - In this work we report on plasma oxidation of palladium (Pd) to form reliable palladium/palladium oxide (Pd/PdO x ) core-shell sensor for ppb level H2S detection and its performance improvement through nanostructuring using hole-mask colloidal lithography (HCL). The plasma oxidation parameters and the sensor operating conditions are optimized to arrive at a sensor device with high sensitivity and repeatable response for H2S. The plasma oxidized palladium/palladium oxide sensor shows a response of 43.1% at 3 ppm H2S at the optimum operating temperature of 200 degrees C with response and recovery times of 24 s and 155 s, respectively. The limit of detection (LoD) of the plasma oxidised beam is 10 ppb. We further integrate HCL, a bottom-up and cost-effective process, to create nanodiscs of fixed diameter of 100 nm and varying heights (10, 15 and 20 nm) on 10 nm thin Pd beam which is subsequently plasma oxidized to improve the H2S sensing characteristics. The nanostructured Pd/PdO x sensor with nanodiscs of 100 nm diameter and 10 nm height shows an enhancement in sensing performance by 11.8% at same operating temperature and gas concentration. This nanostructured sensor also shows faster response and recovery times (15 s and 100 s, respectively) compared to the unstructured Pd/PdO x counterpart together with an experimental LoD of 10 ppb and the estimated limit going all the way down to 2 ppb. Material characterization of the fabricated Pd/PdO x sensors is done using UV-vis spectroscopy and x-ray photoemission spectroscopy. PMID- 29595149 TI - Tunable single and double emission semiconductor nanocrystal quantum dots: a multianalyte sensor. AB - We have prepared stable colloidal CdTe and CdTe/ZnS core-shell quantum dots (QDs) using hot injection chemical route. The developed CdTe QDs emit tunable single and dual photoluminescence (PL) bands, originating from the direct band edge and the surface state of QDs, as evident by the steady-state and time-resolved spectroscopy. The developed CdTe and CdTe/ZnS QDs act as optical sensors for the detection of metal ions (e.g., Fe2+ and Pb2+) in the feed water. The PL quenching in the presence of analytes has been examined by both the steady-state and time resolved PL spectroscopy. The linear Stern-Volmer (S-V) plots obtained for PL intensity and lifetime as a function of metal ion concentration demonstrates the diffusion-mediated collisional quenching as a dominant mechanism together with the possibility of fluorescence resonance energy transfer. Thus, the prepared core and core-shell QDs which cover a broad spectral range of white light with high quantum yield (QY) are highly sensitive to the detection of metal ions in feed water and are also important for biological applications (Ratnesh and Mehata 2017 Spectrochim. Acta A: Mol. Biomol. Spectro. 179 201-10). PMID- 29595150 TI - Spiraling contaminant electrons increase doses to surfaces outside the photon beam of an MRI-linac with a perpendicular magnetic field. AB - The transverse magnetic field of an MRI-linac sweeps contaminant electrons away from the radiation beam. Films oriented perpendicular to the magnetic field and 5 cm from the radiation beam edge show a projection of the divergent beam, indicating that contaminant electrons spiral along magnetic field lines and deposit dose on surfaces outside the primary beam perpendicular to the magnetic field. These spiraling contaminant electrons (SCE) could increase skin doses to protruding regions of the patient along the cranio-caudal axis. This study investigated doses from SCE for an MRI-linac comprising a 7 MV linac and a 1.5 T MRI scanner. Surface doses to films perpendicular to the magnetic field and 5 cm from the radiation beam edge showed increased dose within the projection of the primary beam, whereas films parallel to the magnetic field and 5 cm from the beam edge showed no region of increased dose. However, the dose from contaminant electrons is absorbed within a few millimeters. For large fields, the SCE dose is within the same order of magnitude as doses from scattered and leakage photons. Doses for both SCE and scattered photons decrease rapidly with decreasing beam size and increasing distance from the beam edge. PMID- 29595151 TI - Nitrogen removal via a single-stage PN-Anammox process in a novel combined biofilm reactor. AB - This study developed a partial nitrification (PN) and anaerobic ammonia oxidation (Anammox) process for treating high-ammonia wastewater using an innovative biofilm system in which ammonia oxidizing bacteria grew on fluidized Kaldnes (K1) carriers and Anammox bacteria grew on fixed acryl resin carriers. The airlift loop biofilm reactor (ALBR) was stably operated for more than 4 months under the following conditions: 35 +/- 2 degrees C, pH 7.5-8.0 and dissolved oxygen (DO) of 0.5-3.5 mg/L. The results showed that the total nitrogen removal efficiency reached a maximum of 75% and the total nitrogen removal loading rate was above 0.4 kg/(d.m3). DO was the most efficient control parameter in the mixed biofilm system, and values below 1.5 mg/L were observed in the riser zone for the PN reaction, while values below 0.8 mg/L were observed in the downer zone for the Anammox reaction. Scanning electron microscopy and Fluorescence In Situ Hybridization images showed that most of the nitrifying bacteria were distributed on the K1 carriers and most of the Anammox bacteria were distributed within the acryl resin carriers. Therefore, the results indicate that the proposed combined biofilm system is easy to operate and efficient for the treatment of high-ammonia wastewater. PMID- 29595152 TI - A new achievement in green degradation of aqueous organic pollutants under visible-light irradiation. AB - The global attention has been focused on degradation of the environmental organic pollutants through green methods such as advanced oxidation processes (AOPs) under sunlight. However, AOPs have not yet been efficient in function of the photocatalyst that has been used. In this work, firstly, CaCu3Ti4O12 nanocomposite was simultaneously synthesized and decorated in different amounts of graphene oxide to enhance photodegradation of the organics. The result of the photocatalyst characterization showed that the sample with 8% graphene presented optimum photo-electrical properties such as low band gap energy and a great surface area. Secondly, the photocatalyst was applied for photodegradation of an organic model in a batch photoreactor. Thirdly, to scale up the process and optimize the efficiency, the photodegradation was modeled by multivariate semi empirical methods. As the optimized condition showed, 45 mg/L of the methyl orange has been removed at pH 5.8 by 0.96 g/L of the photocatalyst during 288 min of the light irradiation. Moreover, the photodegradation has been scaled up for industrial applications by determining the importance of the input effective variables according to the following organics order > photocatalyst > pH > irradiation time. PMID- 29595153 TI - Performance of a membrane bioreactor in extreme concentrations of bisphenol A. AB - In this study, a submerged membrane bioreactor was used to study the effect of low and high bisphenol A (BPA) concentration on the sludge biological activity. The pilot was operated over 540 days with hydraulic retention time and solid retention time of 5.5 hours and 140 days, respectively. As a hydrophobic compound, BPA was highly adsorbed by activated sludge. In lower concentrations, the biodegradation rate remained low, since the BPA concentration in the sludge was lower than 0.5 mg/g TS; yet, at an influent concentration up to 15 mg/L, the biodegradation rate was increasing, resulting in 99% BPA removal efficiency. The result for chemical oxygen demand removal showed that BPA concentration has no effect on the heterotrophic bacteria that were responsible for the organic carbon degradation. In higher concentrations, up to 16 mg of BPA was used for each gram of sludge as a source of carbon. However, the activity of autotrophic bacteria, including nitrifiers, was completely halted in the presence of 20 mg/L of BPA or more. Although nitrification was stopped after day 400, ammonia removal remained higher than 70% due to air stripping. Assimilation by bacteria was the only removal pathway for phosphorus, which resulted in an average 35% of P-PO4 removal efficiency. PMID- 29595154 TI - Domestic wastewater treatment by forward osmosis-membrane distillation (FO-MD) integrated system. AB - In this study, real domestic wastewater treatment by forward osmosis-membrane distillation (FO-MD) integrated system was investigated in laboratory scale. The integrated membrane system presented a good separation performance and the removal efficiency of most contaminants in the domestic wastewater was higher than 90%. High molecular weight contaminants were completely removed, while a few low molecular weight contaminants permeated through the membrane. The FO membrane fouling layer mainly consisted of organic substances like polysaccharides and proteins, and was very loose and could be effectively removed by rinsing the membrane surface with tap water. By comparison, the MD membrane fouling was mainly induced by inorganic salts and was not as severe as that of the FO membrane. During 120 h continuous operation, the FO-MD integrated system exhibited satisfying performance stability and maintained a high water yield and high product water quality. The results indicated the potential of the FO-MD integrated system for municipal wastewater treatment in coastal cities, water purification and desalination.

AB - Simultaneous removal of carbon and nutrients (CNP) in a single laboratory-scale bioreactor is advantageous in terms of reactor volume and energy consumption. In this study, an innovative up-flow anaerobic/anoxic/aerobic (A2O) single bioreactor with continuous feed and intermittent discharge (CFID) regime equipped with a movable aerator in the reactor height for simultaneous removal of CNP from soft drinks wastewater was successfully designed, fabricated and operated. The effects of four independent variables, i.e. hydraulic retention time (HRT), aerator height, biomass concentration and nitrogen/soluble chemical oxygen demand (N/sCOD) ratio at three levels in the range of 4-8 h, 37-55.5 cm, 4,000-6,000-1, and 0.05-0.2, respectively, on eight process responses were investigated. The central composite design (CCD) and response surface methodology (RSM) were applied to design the experimental conditions, model the obtained data, and optimize the process. The bioreactor provides three conditions with different dissolved oxygen (DO) (anaerobic, anoxic and aerobic) in a single bioreactor by placing the aerator in the middle of the reactor. As a result, the maximum sCOD, total nitrogen (TN) and total phosphorus (TP) removal were about 100, 92 and 41%, respectively. The optimum region obtained was an HRT of 5-11 h, a mixed liquor suspended solids (MLSS) concentration of 4,000-4,700 mgL-1, and an aerator height of 46.25 cm, at the N/sCOD ratio of 0.1. PMID- 29595156 TI - Structural characteristics of extracellular polymeric substances (EPS) in membrane bioreactor and their adsorptive fouling. AB - The soluble (S), loosely bound (LB) and tightly bound (TB) extracellular polymeric substances (EPS) were extracted from sludge flocs of a membrane bioreactor to evaluate their characteristics and adsorptive fouling. The degrees of adsorptive fouling by the EPS fractions were in the order S-EPS < TB-EPS < LB EPS. The images of atomic force microscopy showed the membrane fouled by LB-EPS was rougher than that fouled by the other fractions. The adsorbed EPS layer, which was sensed by quartz crystal microbalance with dissipation, was found to be more rigid and compact for LB-EPS, compared with the other EPS fractions. The excitation-emission matrix and Fourier transform infrared techniques were also used to characterize the individual EPS fractions. Compared with S-EPS and TB EPS, the LB-EPS contained a larger amount of aromatic protein and less carbohydrates and lipids, exhibiting characteristics of greater aromaticity and hydrophobicity. These characteristics should be responsible for more severe fouling, and the stiffer and more compact structure of the adsorbed layer. PMID- 29595157 TI - Removal of toxic metals using endocarp of acai berry as biosorbent. AB - The effectiveness of acai endocarp as biosorbent for removal of Cd2+, Pb2+ and Cr3+ from single solute solutions was analyzed. The biomass of acai endocarp was characterized by scanning electron microscopy, infrared spectroscopy and determining the point of zero charge. The optimum conditions for adsorption process were obtained at solution pH 6.0 for Cd(II) removal, pH 5.0 for Pb(II) removal, and, pH 4.0 for Cr(III). Furthermore, the average optimum efficiency of biosorbent in the optimum conditions was 8, 20 and 12 g of biosorbent per litre of contaminant solution, respectively, for Cd(II), Pb(II) and Cr(III). The best dynamic equilibrium time was reached at 60 min and Langmuir's model had the best fit for Cd(II) and Cr(III) biosorption, indicating a monolayer adsorption. Freundlich's model exhibited the best fit for Pb(II) ion. Elution rates were low, indicating a strong metal interaction with the adsorbent's surface. Thermodynamic parameters showed a spontaneous and endothermal process in the case of Cd(II) and Pb(II) ions, but not for Cr(III) ion, which appears to be an exothermic process. Results show that the use of the acai biosorbent may be a promising alternative for the remediation of polluted water, due to its low cost and highly availability. PMID- 29595158 TI - Optimization of the synthesis and operational parameters for NOM removal with response surface methodology during nano-composite membrane filtration. AB - The aim of this study was to investigate membrane synthesis by interfacial polymerization methods, the application of synthesized nano-composite membrane for natural organic matters (NOMs) removal from water, evaluation of fouling mechanism and antifouling properties. Polysulfone (PSf) was selected as a porous ultrafiltration membrane support and interfacial polymerization was done using tannic acid (TA) and Trimesoyl chloride (TMC) with central composite design (CCD). The effects of TA and TMC monomer concentrations, reaction time and post treatment temperature was evaluated. The synthesized membrane was characterized by field emission scanning electron microscope (FESEM), atomic force microscopy (AFM), attenuated total reflection Fourier transform infrared spectroscopy (ATR FTIR) and water contact angle. Based on the results, the optimum conditions for synthesizing nano-composite were: TA concentration of 0.27 g/L, TMC concentration of 0.22 g/L, reaction time of 68.29 min and temperature of 25.23 degrees C. The predicted optimum operational conditions were a NOM concentration of 6.429 mg/L; time of 10.931 min and applied pressure of 1.039 bar. The potential applications of the synthesized nano-composite membranes with interfacial polymerization can enhance water treatment. PMID- 29595159 TI - Polyacrylic acid grafted silica fume as an excellent adsorbent for dysprosium(III) removal from industrial wastewater. AB - In the development of industrial life, an enormous amount of silica fume (SF) has been accumulated and cannot be reused properly, and a large quantity of rare earth elements in industrial wastewater has been inappropriately discharged, both of which pose a threat to human health and the environment. By using UV photocatalytic grafting technology, a polymer brush grafted from modified SF, which can be used as a high efficiency adsorbent, can solve both problems at the same time. Specifically, SF was firstly silanol-functionalized by gamma methacryloxypropyltrimethoxysilane (KH570), then grafted with polyacrylic acid brushes by UV photocatalytic grafting to finally obtain the adsorbent. Under optimal conditions, adsorption capacity of the adsorbent for dysprosium(III) (Dy3+) could reach 278.49 mg/g. It took 1 min for the adsorbent to reach adsorbing equilibrium at a relatively low concentration of Dy3+ (40 mg/L), and only 3 min at a medium and high concentration (130 mg/L and 200 mg/L). After six adsorption-desorption cycles, the adsorbent still possessed high adsorption capacity for Dy3+ (251.20 mg/g). The adsorption behavior of the adsorbent fit the Langmuir isotherm model (R2 > 0.97) and pseudo-second-order kinetic model (R2 > 0.98) well. The functional group of carboxylate anion, -COO-, played a central role during the adsorption process, which was verified by Fourier transform infrared and X-ray photoelectron spectroscopy analyses.

AB - This work presents the performance of a sequencing batch reactor (SBR) system used as a means of removing nitrogen from domestic wastewater containing a low chemical oxygen demand (COD) to nitrogen ratio due to pre-treatment with an anaerobic reactor. The aim of the work was to determine the feasibility of this system for the removal of nitrogen from the domestic wastewater. An SBR with a working volume of 5 L was investigated at different cycle times of 12, 8 and 6 h, at 18 degrees C. The efficiency of the SBR varied together with the duration of the cycle, where the optimum performance was seen in the 6 h cycle with the anoxic-aerobic-anoxic sequence. Due to the low quantity of organic matter present in the domestic wastewater after the anaerobic treatment, an additional supply of external carbon was necessary before the second anoxic stage. The removal efficiencies obtained were: 98% for total Kjeldahl nitrogen, 84% for total nitrogen and 77% for soluble COD. The reactor was thus shown to be viable, and it was concluded that this process may be successfully applied as a post-treatment for the removal of nitrogen from anaerobically treated domestic wastewater. PMID- 29595161 TI - Preparation of granular activated carbons from composite of powder activated carbon and modified beta-zeolite and application to heavy metals removal. AB - Heavy metals are continuously contaminating the surface and subsurface water. The adsorption process is an attractive alternative for removing the heavy metals because of its low cost, simple operation, high efficiency, and flexible design. In this study, influences of beta-zeolite and Cu-modified beta-zeolite on preparation of granular activated carbons (GACs) from a composite of powder activated carbon (PAC), methylcellulose as organic binder, bentonite as inorganic binder, and water were investigated. A number of granular samples were prepared by controlling the weight percentage of binder materials, PAC and zeolites as a reinforcing adsorbent. Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction techniques were employed to characterize zeolite, modified zeolite and produced GAC. The produced GACs were used as the adsorbent for removal of Zn+2, Cd2+ and Pb2+ ions from aqueous solutions. The results indicated that the adsorption of metals ions depended on the pH (5.5) and contact time (30 min). Maximum adsorption of 97.6% for Pb2+, 95.9% for Cd2+ and 91.1% for Zn+2 occurred with a new kind of GAC made of Cu-modified beta-zeolite. The Zn+2, Cd2+ and Pb2+ ions sorption kinetics data were well described by a pseudo-second order model for all sorbents. The Langmuir and Freundlich isotherm models were applied to analyze the experimental equilibrium data.

AB - Azo dyes are being extensively used in textile industries, so finding a proper solution to decolorize them is of high importance. In order to find azo dye decolorizing strains among haloarchaea, which are well known for their tolerance to harsh environmental conditions, fifteen haloarchaeal strains were screened. Halogeometricum sp. strain A and Haloferax sp. strain B with the highest decolorization ability (95% and 91% for Remazol black B; both about 60% for Acid blue 161, respectively) were selected for further studies. It was shown that both strains were able to grow and decolorize the dye in a medium containing up to 5 M NaCl, with optimum decolorization activity at 2.5-3.4 M, pH 7, and a wide temperature range between 30 to 45 degrees C. Moreover, both strains were able to tolerate and decolorize up to 1,000 mg l-1 Remazol black B. Also, they were able to survive in 5,000 mg l-1 of the dye after 20 days' incubation. Glucose and yeast extract were found to be the best carbon and nitrogen sources in the decolorization medium for both strains. This is the first report studying decolorization of azo dyes using halophilic archaea. PMID- 29595163 TI - Biosorption of cationic dyes by Para chestnut husk (Bertholletia excelsa). AB - Para chestnut husk (Bertholletia excelsa) (PCH), an agro-industrial waste largely generated in Brazil, was employed as a low-cost and efficient biosorbent to remove the cationic dyes Crystal Violet (CV) and Methylene Blue (MB) from aqueous media. PCH presented an amorphous structure containing carboxylic acids, esters, ketones and aldehydes on the surface. Non-porous and irregular particles were also observed. For both dyes, the biosorption capacity was favored under acid conditions. Equilibrium was attained within 40 min at 25 degrees C with a PCH dosage of 0.5 g L-1. The biosorption kinetic curves were satisfactory explained by the pseudo-first-order model. The Freundlich model was best for representing the equilibrium curves. The maximum biosorption capacities were 83.6 and 83.8 mg g-1 for CV and MB, respectively. PCH was efficient for treating a simulated textile effluent containing several dyes and chemicals, achieving a color removal of 90%. In this way, PCH can be considered as an option for treating colored effluents containing textile dyes.

AB - In this study, the remediation experiments were performed outdoors in natural conditions. Carboxymethyl cellulose (CMC)-stabilized nanoscale zero-valent iron (CMC-nZVI), biochar (BC) and CMC-stabilized nanoscale zero-valent iron composited with biochar (CMC-nZVI/BC) were synthesized and investigated for their effect on the in situ remediation of hexavalent chromium [Cr(VI)] contaminated soil and the concentration of available iron was tested after the remediation, compared with the untreated soil. The results of toxicity characteristic leaching procedure (TCLP) test showed that CMC-nZVI and CMC-nZVI/BC used as remediation materials could obviously improve the remediation rate of Cr contaminated soil and when the ratio of CMC-nZVI to Fe0 was 2.5 g/Kg, the leachability of Cr(VI) and Crtotal can be reduced by 100% and 95.8% simultaneously. Moreover, sequential extraction procedure (SEP) showed that most exchangeable Cr converted to carbonate-bound and Fe-Mn oxides-bound, reducing the availability and leachability of Cr in the soil. PMID- 29595165 TI - Assessing the impact of sea level rise due to climate change on seawater intrusion in Mekong Delta, Vietnam. AB - In the context of climate change, salinity intrusion into rivers has been, and will be, one of the most important issues for coastal water resources management. A combination of changes, including increased temperature, change in regional rainfall, especially sea level rise (SLR) related to climate change, will have significant impacts on this phenomenon. This paper presents the outcomes of a study conducted in the Mekong Delta of Vietnam (MKD) for evaluating the effect of sea water intrusion under a new SLR scenario. Salinity intrusion was simulated by one-dimensional (1D) modeling. The relative sea level projection was constructed corresponding to the RCP 6.0 emission scenario for MKD based on the statistical downscaling method. The sea level in 2050 is projected to increase from 25 cm to 30 cm compared to the baseline period (in 2000). Furthermore, the simulated results suggested that salinity greater than 4 g/l, which affects rice yield, will intrude up to 50-60 km into the river. Approximately 30,000 ha of agricultural area will be affected if the sea level rise is 30 cm. PMID- 29595166 TI - Assessing the robustness of raingardens under climate change using SDSM and temporal downscaling. AB - Climate change is expected to lead to higher precipitation amounts and intensities causing an increase of the risk for flooding and combined sewer overflows in urban areas. To cope with these changes, water managers are requesting practical tools that can facilitate adaptive planning. This study was carried out to investigate how recent developments in downscaling techniques can be used to assess the effects of adaptive measures. A combined spatial-temporal downscaling methodology using the Statistical DownScaling Model-Decision Centric (SDSM-DC) and the Generalized Extreme Value distribution was applied to project future precipitation in the city of Bergen, Norway. A raingarden was considered a potential adaptive measure, and its performance was assessed using the RECARGA simulation tool. The benefits and limitations of using the proposed method have been demonstrated and compared to current design practices in Norway. Large differences in the raingarden's performance with respect to percentage overflow and lag-time reduction were found for varying projections. This highlights the need for working with a range of possible futures. Further, it was found that Ksat was the determining factor for peak-flow reduction and that different values of Ksat had different benefits. Engineering flexible solutions by combining measures holding different characteristics will induce robust adaptation. PMID- 29595167 TI - Oxidation of tartrazine with ultraviolet light emitting diodes: pH and duty cycles effects. AB - The presence of tartrazine (TAR) in the water cycle poses serious threats to human health. This study investigated the used of light emitting diodes (LEDs) in the advanced oxidation of TAR under different pH and duty cycle (DC) conditions. The first order reaction rate constant for TAR oxidation was positively correlated with DC, negatively correlated with pH, and typically greatest at pH 6. Chemical byproduct analysis indicated that OH addition, H abstraction, and electron transfer without molecule transfer were among the relevant reaction mechanisms for TAR degradation. Six byproducts were identified, four were reported for the first time, and two demonstrated that TAR rings were cleaved. This research is the first to determine the optimal pH for UVLED-driven oxidation of TAR and the first to identify new TAR-related byproducts from UVLED-based water treatment. PMID- 29595168 TI - Formulation of a minimal nutritional medium for enhanced lipid productivity in Chlorella sp. and Botryococcus sp. using response surface methodology. AB - Chlorella sp. MCC 7 and Botryococcus sp. MCC 31 were investigated to enable large scale biodiesel production from minimal constituents in the growth medium. Response surface methodology (RSM) was used to maximise the biomass productivity and lipid yield using only nitrogen (N), phosphorus (P) and potassium (K) as urea, single super phosphate and muriate of potash. The optimum values were 0.42 g/L nitrogen; 0.14 g/L phosphorus and 0.22 g/L potassium for Chlorella sp.; and 0.46 g/L; 0.14 g/L and 0.25 g/L for Botryococcus sp. Lipid yield of 42% for Chlorella sp. and 52% in Botryococcus sp. was observed. An enhancement in lipid yield by approximately 55% for Chlorella sp. and 73% for Botryococcus sp. was registered as compared to original nutrient medium. Fourier transform infrared (FTIR) analysis of extracted lipids revealed characteristic bands for triglycerides. This study provided utilisation of a practicable nutrient recipe in the form of N, P, K input for enhanced lipid yield from the selected microalgal strains. PMID- 29595169 TI - Changes in estrogenicity and micropollutant concentrations across unit processes in a biological wastewater treatment system. AB - The behavior of 10 micropollutants, i.e. four estrogens (estrone, 17beta estradiol, estriol, 17alpha-ethynylestradiol), carbamazepine (CBZ), sulfamethoxazole (SMX), triclosan, oxybenzone, 4-nonylphenol, and bisphenol A, was investigated in a typical domestic wastewater treatment plant. LC-MS and yeast estrogen screen bioassay were used to study the changes in micropollutants and estrogenicity across unit processes in the treatment system. Primary treatment via sedimentation showed that only 4-nonylphenol was removed, but led to no significant change in estrogenicity. Secondary treatment by the biological nitrification-dentrification process showed complete removal of oxybenzone and partial removal of the estrogens, which led to a decrease in estrogenic activity from 80 to 48 ng/L as estradiol equivalent (EEq). Ultraviolet treatment completely degraded the estrogens and triclosan, but failed to lower the concentrations of bisphenol A, SMX, and CBZ; a decrease in estrogenic activity from 48 to 5 ng/L EEq across the unit, a value that was only slightly larger than the observed EEq of 1 ng/L for the deionized control. Similarly, the anaerobic digestion of sludge completely degraded estrogens, oxybenzone, and SMX, but had no impact on bisphenol A, triclosan, and CBZ. The study emphasises the need to complement chemical analyses with estrogenic bioassays to evaluate the efficacy of waste water treatment plants. PMID- 29595170 TI - The enhanced effect of activated sludge attached to the roots of Pistia stratiotes on nutrient removal for secondary effluent. AB - Aquatic plants are widely used for treating wastewater treatment plant secondary effluent. During this process, some residual activated sludge in the secondary effluent is intercepted and attaches to the plant roots. However, the effect of the attached activated sludge on nutrient removal in secondary effluent has up to now been unknown. Aiming at this problem, this investigation was conducted to compare the nutrient removal rates in secondary effluent by washed Pistia stratiotes (washed batch) and Pistia stratiotes with activated sludge attached to the roots (study batch). Extracellular polymeric substances (EPS) from the activated sludge attached to the roots were extracted and characterized by three dimensional excitation emission matrix (3D-EEM) fluorescence spectroscopy. The results showed that the nutrient removal rates in the study batch were better than that in the washed batch. The 3D-EEM results showed that the protein content of EPS increased during the experiment, indicating the growth of microorganisms in the attached activated sludge. Our work demonstrated the enhanced effect of activated sludge attached to the roots of Pistia stratiotes on the removal of pollutants in secondary effluent, which is useful to guide the practical engineering of secondary effluent treatment. PMID- 29595171 TI - Identifying critical components causing seasonal variation of activated sludge settleability and developing early warning tool. AB - Settleability of activated sludge is one of the most common problems that restricts the efficiency of activated sludge system. Obvious seasonal variation of settleability was found in the activated sludge system of a full scale wastewater treatment plant (WWTP) during 2 years of observation. Principal component analysis (PCA) was applied to study the correlation between diluted sludge volume index (DSVI), operational and environmental factors. As a result, temperature and mixed liquid suspended solids (MLSS) were found as the most significant variables relating with DSVI variation. Multivariate regression, partial least squares regression and support vector machine regression were applied to develop early warning models for DSVI prediction. The multivariate regression model was proved as a simple and easy-to-interpret early warning tool to be applied in practice. Based on the ratio of volatile substances in biomass, the original cause of seasonal variation of settleability was further discussed by referring the storage-biodegradation mechanism. Moreover, the results of this work also suggested that modern statistical techniques were important to investigate complicated engineering problems. This study provided insights of seasonal variation of activated sludge settleability by systematic investigation of long-term data of a full scale WWTP. PMID- 29595172 TI - Abundance and community structure of ammonia-oxidizing bacteria in activated sludge from different geographic regions in China. AB - Detailed ecological information on ammonia-oxidizing bacteria (AOB) in activated sludge of wastewater treatment plants (WWTPs) is very important to improve the efficiency of wastewater treatment. In this study, activated sludge samples were collected from seven municipal WWTPs located in seven cities in China, and real time quantitative polymerase chain reaction (qPCR), as well as construction of clone libraries combined with correlation-based data analysis was performed. Further, the effect of geographic distribution and some water quality parameters on the ecological distribution of AOB in activated sludge from WWTPs were investigated. The geographic distribution, the influent concentration of total nitrogen (TN) and ammonia nitrogen (NH4+-N) had significant effects on the abundance of AOB (P < 0.05). However, the community structure of AOB were not significantly affected by geographic distribution, but by water quality parameters including the concentrations of TN and NH4+-N. N. oligotropha lineage was the dominant AOB group in the wastewater treatment systems. The results obtained in this study provide useful information to understand some aspects of the ecological information and influencing factors of AOB in geographically distributed WWTPs. PMID- 29595173 TI - In situ continuous monitoring of nitrogen with ion-selective electrodes in a constructed wetland receiving treated wastewater: an operating protocol to obtain reliable data. AB - Constructed wetlands receiving treated wastewater (CWtw) are placed between wastewater treatment plants and receiving water bodies, under the perception that they increase water quality. A better understanding of the CWtw functioning is required to evaluate their real performance. To achieve this, in situ continuous monitoring of nitrate and ammonium concentrations with ion-selective electrodes (ISEs) can provide valuable information. However, this measurement needs precautions to be taken to produce good data quality, especially in areas with high effluent quality requirements. In order to study the functioning of a CWtw instrumented with six ISE probes, we have developed an appropriate methodology for probe management and data processing. It is based on an evaluation of performance in the laboratory and an adapted field protocol for calibration, data treatment and validation. The result is an operating protocol concerning an acceptable cleaning frequency of 2 weeks, a complementary calibration using CWtw water, a drift evaluation and the determination of limits of quantification (1 mgN/L for ammonium and 0.5 mgN/L for nitrate). An example of a 9-month validated dataset confirms that it is fundamental to include the technical limitations of the measuring equipment and set appropriate maintenance and calibration methodologies in order to ensure an accurate interpretation of data. PMID- 29595174 TI - The formation of hybrid carbon nanomaterial by chemical vapor deposition: an efficient adsorbent for enhanced removal of methylene blue from aqueous solution. AB - In this study, carbon species were grown on the surface of Ni-impregnated powder activated carbon to form a novel hybrid carbon nanomaterial by chemical vapor deposition. The carbon nanomaterial was obtained by the precipitation of the methane elemental carbon atoms on the surface of the Ni catalyst. The physiochemical properties of the hybrid material were characterized to illustrate the successful growth of carbon species on the carbon substrate. The response surface methodology was used for the evaluation of adsorption parameters effect such as pH, adsorbent dose and contact time on the percentage removal of MB dye from aqueous solution. The optimum conditions were found to be pH = 11, adsorbent dose = 15 mg and contact time of 120 min. The material we prepared showed excellent removal efficiency of 96% for initial MB concentration of 50 mg/L. The adsorption of MB was described accurately by the pseudo-second-order model with R2 of 0.998 and qe of 163.93 (mg/g). The adsorption system showed the best agreement with Langmuir model with R2 of 0.989 and maximum adsorption capacity (Qm) of 250 mg/g. PMID- 29595175 TI - Modelling the effects of meteorological parameters on water temperature using artificial neural networks. AB - Water temperature affects all biological and chemical processes in water; therefore, it is an extremely important water quality parameter. Meteorological factors are among the most important factors that affect water temperatures. The aim of this study is to develop an artificial neural network (ANN) model to investigate the effects of meteorological parameters on water temperatures at Kizilirmak River in Turkey. Water temperature data were collected from gauging stations on Kizilirmak River, and meteorological data were acquired from the nearest meteorological stations. Air temperature, wind speed, relative humidity, and previous water temperatures were formed the input parameters. The model output included water temperatures. All data were available for the 1995-2007 period, with occasional missing records. The activation functions of the ANN model and the number of neurons in the hidden layer were selected by trial-and error method to find the best results. The root mean square error and the correlation coefficient between observed and simulated water temperatures were used to assess the model success. The best results were obtained by using sigmoid activation function and scaled conjugate gradient algorithm. This study showed that meteorological data can be used to simulate water temperature with ANN model for Kizilirmak River. PMID- 29595176 TI - Decolourization of malachite green dye by mentha plant biochar (MPB): a combined action of adsorption and electrochemical reduction processes. AB - Adsorption behavior of mentha (mint) plant biochar (MPB) in removal of malachite green (MG) dye from aqueous solution was analyzed as a function of different pH (4.0-10.0), initial dye concentration (20-100 mg/L), contact time (0-45 min) and dose of adsorbent (0.05-0.3 g/100 mL). The zeta potential of the MPB particles was found to be -37.9 mV, indicating a negatively charged sorption surface of MPB particles. MPB was found to be more effective in removal of MG dye at pH 6.0 due to combined action of physico-chemisorption and a reductive electron transfer reaction. Results on the Brunauer-Emmett-Teller (BET) analysis of the N2 adsorption-desorption isotherm of MPB as adsorbent showed sigmoidal shape similar to the type IV isotherm and mesoporous nature. The cyclic voltammetric analysis of MG dye showed a reversible, coupled redox reaction at the interface of dye molecules and MPB particles. The maximum monolayer adsorption capacity (qmax) of MPB was found to be 322.58 mg g-1. The separation factor (RL) value was between 0 and 1, indicating a favourable adsorption of MG dye onto MPB. The results fitted well to a pseudo-second-order kinetic model. Further results from desorption experiments showed recovery of MG dye by about 50% in the presence of 1 N HCl. PMID- 29595177 TI - Effect of water-to-cement ratio and curing method on the strength, shrinkage and slump of the biosand filter concrete body. AB - The biosand filter is a household-level water treatment technology used globally in low-resource settings. As of December 2016, over 900,000 biosand filters had been implemented in 60 countries around the world. Local, decentralized production is one of the main advantages of this technology, but it also creates challenges, especially in regards to quality control. Using the current recommended proportions for the biosand filter concrete mix, slump was measured at water-to-cement ratios of 0.51, 0.64 and 0.76, with two replicates for each level. Twenty-eight-day strength was tested on four replicate cylinders, each at water-to-cement ratios of 0.51, 0.59, 0.67 and 0.76. Wet curing and dry curing were compared for 28-day strength and for their effect on shrinkage. Maximum strength occurred at water-to-cement ratios of 0.51-0.59, equivalent to 8-9.3 L water for a full-scale filter assuming saturated media, corresponding to a slump class of S1 (10-40 mm). Wet curing significantly improved strength of the concrete mix and reduced shrinkage. Quality control measures such as the slump test can significantly improve the quality within decentralized production of biosand filters, despite localized differences in production conditions. PMID- 29595178 TI - Relevance of n-butanol as a reference gas for odorants and complex odors. AB - Odor analysis by olfactometry relies on the use of n-butanol as a reference compound for standardizing the selection of human panelists. This requires that human sensitivity towards n-butanol is correlated to sensitivity towards other odorants as well as complex odor mixtures. However, there is limited evidence in the literature of such correlations. In this work, datasets from three odor laboratories were investigated in order to clarify this. All panels routinely analyzed n-butanol and H2S samples. Two of the laboratories analyzed samples from pig production or industry, whereas one laboratory determined odor threshold values for typical pig production odorants. Non-significant correlations were observed in most cases and odor threshold values for structurally related compounds were not well correlated. The work presented strongly indicates that the sensitivity of odor panelists towards n-butanol is not well transferred to other odorants or odor samples. Furthermore, minimization of variance by using n butanol is not transferable to other odorants or environmental samples. Thus, the harmonization of human panelists for odor analysis based on n-butanol does not appear to result in harmonization with respect to other odorants or odor samples. PMID- 29595179 TI - Attribute-based intervention development for increasing resilience of urban drainage systems. AB - Resilience building commonly focuses on attributes such as redundancy. Whilst this may be effective in some cases, provision of specific attributes does not guarantee resilient performance and research is required to determine the suitability of such approaches. This study uses 250 combined sewer system virtual case studies to explore the effects of two attribute-based interventions (increasing distributed storage and reducing imperviousness) on performance-based resilience measures. These are found to provide improvement in performance under system failure in the majority of case studies, but it is also shown that attribute-based intervention development can result in reduced resilience. PMID- 29595180 TI - Application of electrochemical peroxidation (ECP) process for waste-activated sludge stabilization and system optimization using response surface methodology (RSM). AB - In this study, the performance of the electrochemical peroxidation (ECP) process for removing the volatile suspended solids (VSS) content of waste-activated sludge was evaluated. The Fe2+ ions required by the process were obtained directly from iron electrodes in the system. The performance of the ECP process was investigated in various operational conditions employing a laboratory-scale pilot setup and optimized by response surface methodology (RSM). According to the results, the ECP process showed its best performance when the pH value, current density, H2O2 concentration and the retention time were 3, 3.2 mA/cm2, 1,535 mg/L and 240 min, respectively. In these conditions, the introduced Fe2+ concentration was approximately 500 (mg/L) and the VSS removal efficiency about 74%. Moreover, the results of the microbial characteristics of the raw and the stabilized sludge demonstrated that the ECP process is able to remove close to 99.9% of the coliforms in the raw sludge during the stabilization process. The energy consumption evaluation showed that the required energy of the ECP reactor (about 1.8-2.5 kWh (kg VSS removed)-1) is considerably lower than for aerobic digestion, the conventional waste-activated sludge stabilization method (about 2-3 kWh (kg VSS removed)-1). The RSM optimization process showed that the best operational conditions of the ECP process comply with the experimental results, and the actual and the predicted results are in good conformity with each other. This feature makes it possible to predict the introduced Fe2+ concentrations into the system and the VSS removal efficiency of the process precisely.

AB - Ventral hernias (VHs) are common in the bariatric population with incidence of around 8% of patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB). The factors contributing to the incidence of VH includes high intra-abdominal pressures, previous histories of abdominal surgeries, defects in fascial structure and reduced healing tendency. There is a high index of suspicion in BS patients with VH for hernia complications which can be lethal after LRYGB. Here, we present a case where VH complicated the LRYGB surgery. PMID- 29595182 TI - C-reactive protein as predictor of anastomotic complications after minimally invasive oesophagectomy. AB - Background: Anastomotic leaks after oesophagectomy with tabularised stomach replacement are a significant factor in post-operative mortality and morbidity. Early detection and treatment of this complication allow for improving operative and oncological results. When assessing laboratory values - elevation of inflammatory parameters - complicated interpretation is an issue (systemic inflammatory response syndrome, surgical versus non-surgical complication). Results studying the relationship between C-reactive protein (CRP) and complications following oesophagectomies are inconsistent. The aim of our work was to find relationships between the development of post-operative CRP values and the occurrence of anastomotic complications following minimally invasive oesophagectomy (MIE). Materials and Methods: Analysis of the relationship between CRP values and the occurrence of anastomotic complications or the necessity of reoperation following oesophagectomy with tabularised stomach replacement and cervical anastomosis performed using thoracoscopy and laparoscopy in a group of patients operated on for malignancies at our department between 2012 and 2015. Results: A significant difference was found in average CRP values on the 5th day and 7th day following operation between patients with and without leaks (233 mg/l vs. 122.8 mg/l P = 0.003, respectively 208.9 mg/l vs. 121.3 mg/l P = 0.014). However, on the 5th day, the leak was clinically apparent only in one case out of 11 leaks. A significant difference in CRP values on the 5th day was found between patients who needed revision surgery and patients without revision surgery (294 mg/l vs. 133.5 mg/l P = 0.01). Conclusions: Patients after MIE with tabularised stomach replacement and cervical anastomosis complicated by anastomotic leaks or with the necessity for reoperation had a significantly higher CRP values on the 5th day following operation than patients without complications, regardless of the presence of clinical signs of leaks. PMID- 29595183 TI - Gastrointestinal stromal tumours of stomach: Robot-assisted excision with the da Vinci Surgical System regardless of size and location site. AB - AIMS: The role of minimally invasive surgery of gastrointestinal stromal tumours (GISTs) of the stomach remains uncertain especially for large and/or difficult located tumours. We are hereby presenting a single-centre series of robot assisted resections using the da Vinci Surgical System (Si or Xi). SUBJECTS AND METHODS: Data of patients undergoing robot-assisted treatment of gastric GIST were retrieved from the prospectively collected institutional database and a retrospective analysis was performed. Patients were stratified according to size and location of the tumour. Difficult cases (DCs) were considered for size if tumour was> 50 mm and/or for location if the tumour was Type II, III or IV sec. Privette/Al-Thani classification. RESULTS: Between May 2010 and February 2017, 12 consecutive patients underwent robot-assisted treatment of GIST at our institution. DCs were 10/12 cases (83.3%), of which 6/10 (50%) for location, 2/10 (25%) for size and 2/10 (25%) for both. The da Vinci Si was used in 8 patients, of which 6 (75%) were DC, and the da Vinci Xi in 4, all of which (100%) were DC. In all patients, excision was by wedge resection. All lesions had microscopically negative resection margins. There was no conversion to open surgery, no tumour ruptures or spillage and no intraoperative complications. CONCLUSION: Our experience suggests a positive role of the robot da Vinci in getting gastric GIST removal with a conservative approach, regardless of size and location site. Comparative studies with a greater number of patients are necessary for a more robust assessment. PMID- 29595184 TI - Genetic and molecular aspects of androgenetic alopecia. AB - Androgenetic alopecia is the most common form of progressive hair loss in humans. A genetic predisposition and hormonal status are considered as major risk factors for this condition. Several recent advances in molecular biology and genetics have increased our understanding of the mechanisms of hair loss in androgenetic alopecia. We review these advances and examine the trends in the genetic and molecular aspects of androgenetic alopecia. PMID- 29595185 TI - Acute Respiratory Distress Syndrome: Challenge for Diagnosis and Therapy. AB - Objective: Acute respiratory distress syndrome (ARDS) is a devastating clinical syndrome whose diagnosis and therapy are still in question. The aim of this review was to discuss the current challenge for the diagnosis and treatment of ARDS. Data Sources: Data sources were the published articles in English through December 2017 in PubMed using the following key words: "acute respiratory distress syndrome," "definition", "diagnosis," "therapy," "lung protective strategy," "right ventricular dysfunction," and "molecular mechanism." Study Selection: The selection of studies focused on both preclinical studies and clinical studies of therapy of ARDS. Results: The incidence of ARDS is still high, and ARDS causes high intensive care units admissions and high mortality. The Berlin Definition proposed in 2012 is still controversial owing to lack of sensitivity and specificity. ARDS is still under recognition and it is associated with high mortality. Lung protective strategies with low tidal volume (VT) and lung recruitment should consider the physiology of ARDS because ARDS presents lung inhomogeneity; the same low VT might increase local stress and strain in some patients with low compliance, and lung recruitment could injure lungs in ARDS patients with low recruitability and hemodynamic instability. Acute cor pulmonale is common in severe ARDS. ARDS itself and some treatments could worsen acute cor pulmonale. Molecular understanding of the pathogenic contributors to ARDS has improved, but the molecular-associated treatments are still under development. Conclusions: ARDS is a devastating clinical syndrome whose incidence and mortality has remained high over the past 50 years. Its definition and treatments are still confronted with challenges, and early recognition and intervention are crucial for improving the outcomes of ARDS. More clinical studies are needed to improve early diagnosis and appropriate therapy.

AB - Background: The Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients (PARIS) bleeding score is a novel score for predicting the out-of hospital bleeding risk after percutaneous coronary intervention (PCI). However, whether this score has the same value in non-European and American populations is unclear. This study aimed to assess the PARIS bleeding score's predictive value of bleeding in patients after PCI in the Chinese population. Methods: We performed a prospective, observational study of 10,724 patients who underwent PCI from January to December 2013, in Fuwai Hospital, China. We defined the primary end point as major bleeding (MB) according to Bleeding Academic Research Consortium definition criteria including Type 2, 3, or 5. The predictive value of the PARIS bleeding score was assessed with the area under the receiver operating characteristic (AUROC) curve. Results: Of 9782 patients, 245 (2.50%) MB events occurred during the 2 years of follow-up. The PARIS bleeding score was significantly higher in the MB group than that of non-MB group (4.00 [3.00, 5.00] vs. 3.00 [2.00, 5.00], Z = 3.71, P < 0.001). According to risk stratification of the PARIS bleeding score, the bleeding risk in the intermediate- and high-risk groups was 1.50 times (hazard ratio [HR]: 1.50; 95% confidence interval [CI]: 1.160-1.950; P = 0.002) and 2.27 times higher (HR: 2.27; 95% CI: 1.320-3.900; P = 0.003) than that in the low-risk group. The PARIS bleeding score showed a moderate predictive value for MB in the overall population (AUROC: 0.568, 95% CI: 0.532-0.605; P < 0.001) and acute coronary syndrome (ACS) subgroup (AUROC: 0.578, 95% CI: 0.530-0.626; P = 0.001) and tended to be predictive in the non-ACS subgroup (AUROC: 0.556, 95% CI: 0.501-0.611; P = 0.054). Conclusion: The PARIS bleeding score shows good clinical value for risk stratification and has a significant, but relatively limited, prognostic value for out-of-hospital bleeding in the Chinese population after PCI.

AB - BACKGROUND The aim of this study was to investigate the expression and silencing of the S100A8 gene, which encodes the S100 calcium-binding protein A8 (S100A8), and apoptosis and phosphorylation of protein kinase B (Akt) in tissue samples of endometrial carcinoma and HEC-1A endometrial adenocarcinoma cells in vitro. MATERIAL AND METHODS Immunohistochemistry (IHC) was used to detect expression of the S100A8 protein in 74 tissue samples of endometrial cancer and 22 normal endometrial tissue samples. A stable S100A8 gene knockdown cell line was constructed using lentiviral packing short hairpin RNA (shRNA) transfected into HEC-1A cells. S100A8 mRNA and S100A8 protein levels were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting. The effects of expression of the S100A8 gene by endometrial cancer cells was investigated by the MTT assay, cell cycle and apoptotic assays, qRT-PCR, and Western blotting. RESULTS IHC showed high levels of expression of S100A8 protein in endometrial carcinoma tissues, and HEC-1A adenocarcinoma cells (in G1 and G2). Increased expression of S100A8 protein was found endometrial cancer tissues compared with normal endometrial tissues (79.7% vs. 4.5%). S100A8 gene knockdown reduced cell proliferation in the HEC-1A cells compared with control cells, induced cell apoptosis, inhibited the phosphorylation of protein kinase B (Akt), and induced the expression of pro-apoptotic genes, including the cytochrome C gene, CYCS, BAD, BAX, FOXO1, FOXO3, CASP9, and CASP3. CONCLUSIONS In endometrial carcinoma cells, down-regulation of the S100A8 gene induced cell apoptosis via inhibition of the phosphorylated or active form of protein kinase B (Akt).

AB - Neuritin is a member of the neurotrophic factor family, which is activated by neural activity and neurotrophins, and promotes neurite growth and branching. It has shown to play an important role in neuronal plasticity and regeneration. It is also involved in other biological processes such as angiogenesis, tumorigenesis and immunomodulation. Thus far, however, the primary mechanisms of neuritin, including whether or not it acts through a receptor or which downstream signals might be activated following binding, are not fully understood. Recent evidence suggests that neuritin may be a potential therapeutic target in several neurodegenerative diseases. This review focuses on the recent advances in studies regarding the newly identified functions of neuritin and the signaling pathways related to these functions. We also discuss current hot topics and difficulties in neuritin research. PMID- 29595192 TI - Blockade of the swelling-induced chloride current attenuates the mouse neonatal hypoxic-ischemic brain injury in vivo. AB - Activation of swelling-induced Cl- current (ICl,swell) during neonatal hypoxia ischemia (HI) may induce brain damage. Hypoxic-ischemic brain injury causes chronic neurological morbidity in neonates as well as acute mortality. In this study, we investigated the role of ICl,swell in hypoxic-ischemic brain injury using a selective blocker, 4-(2-butyl-6,7-dichloro-2-cyclopentylindan-1-on-5-yl) oxybutyric acid (DCPIB). In primary cultured cortical neurons perfusion of a 30% hypotonic solution activated ICl,swell, which was completely blocked by the application of DCPIB (10 MUmol/L). The role of ICl,swell in neonatal hypoxic ischemic brain injury in vivo was evaluated in a modified neonatal hypoxic ischemic brain injury model. Before receiving the ischemic insult, the mouse pups were injected with DCPIB (10 mg/kg, ip). We found that pretreatment with DCPIB significantly reduced the brain damage assessed using TTC staining, Nissl staining and whole brain imaging, and improved the sensorimotor and vestibular recovery outcomes evaluated in neurobehavioural tests (i.e. geotaxis reflex, and cliff avoidance reflex). These results show that DCPIB has neuroprotective effects on neonatal hypoxic-ischemic brain injury, and that the ICl,swell may serve as a therapeutic target for treatment of hypoxic-ischemic encephalopathy.

PMID- 29595193 TI - Xyloketal B exerts antihypertensive effect in renovascular hypertensive rats via the NO-sGC-cGMP pathway and calcium signaling. AB - Xyloketal B (Xyl-B) is a novel marine compound isolated from mangrove fungus Xylaria sp. (No 2508). We previously showed that Xyl-B promoted endothelial NO release and protected against atherosclerosis through the Akt/eNOS pathway. Vascular NO production regulates vasoconstriction in central and peripheral arteries and plays an important role in blood pressure control. In this study, we examined whether Xyl-B exerted an antihypertensive effect in a hypertensive rat model, and further explored the possible mechanisms underlying its antihypertensive action. Administration of Xyl-B (20 mg.kg-1.d-1, ip, for 12 weeks) significantly decreased the systolic and diastolic blood pressure in a two kidney, two-clip (2K2C) renovascular hypertensive rats. In endothelium-intact and endothelium-denuded thoracic aortic rings, pretreatment with Xyl-B (20 MUmol/L) significantly suppressed phenylephrine (Phe)-induced contractions, suggesting that its vasorelaxant effect was attributed to both endothelial-dependent and endothelial-independent mechanisms. We used SNP, methylene blue (MB, guanylate cyclase inhibitor) and indomethacin (IMC, cyclooxygenase inhibitor) to examine which endothelial pathway was involved, and found that MB, but not IMC, reversed the inhibitory effects of Xyl-B on Phe-induced vasocontraction. Moreover, Xyl-B increased the endothelial NO bioactivity and smooth muscle cGMP level, revealing that the NO-sGC-cGMP pathway, rather than PGI2, mediated the anti-hypertensive effect of Xyl-B. We further showed that Xyl-B significantly attenuated KCl induced Ca2+ entry in smooth muscle cells in vitro, which was supposed to be mediated by voltage-dependent Ca2+ channels (VDCCs), and reduced ryanodine induced aortic contractions, which may be associated with store-operated Ca2+ entry (SOCE). Taken together, these findings demonstrate that Xyl-B exerts significant antihypertensive effects not only through the endothelial NO-sGC-cGMP pathway but also through smooth muscle calcium signaling, including VDCCs and SOCE.

PMID- 29595191 TI - Targeting RNS/caveolin-1/MMP signaling cascades to protect against cerebral ischemia-reperfusion injuries: potential application for drug discovery. AB - Reactive nitrogen species (RNS) play important roles in mediating cerebral ischemia-reperfusion injury. RNS activate multiple signaling pathways and participate in different cellular events in cerebral ischemia-reperfusion injury. Recent studies have indicated that caveolin-1 and matrix metalloproteinase (MMP) are important signaling molecules in the pathological process of ischemic brain injury. During cerebral ischemia-reperfusion, the production of nitric oxide (NO) and peroxynitrite (ONOO-), two representative RNS, down-regulates the expression of caveolin-1 (Cav-1) and, in turn, further activates nitric oxide synthase (NOS) to promote RNS generation. The increased RNS further induce MMP activation and mediate disruption of the blood-brain barrier (BBB), aggravating the brain damage in cerebral ischemia-reperfusion injury. Therefore, the feedback interaction among RNS/Cav-1/MMPs provides an amplified mechanism for aggravating ischemic brain damage during cerebral ischemia-reperfusion injury. Targeting the RNS/Cav 1/MMP pathway could be a promising therapeutic strategy for protecting against cerebral ischemia-reperfusion injury. In this mini-review article, we highlight the important role of the RNS/Cav-1/MMP signaling cascades in ischemic stroke injury and review the current progress of studies seeking therapeutic compounds targeting the RNS/Cav-1/MMP signaling cascades to attenuate cerebral ischemia reperfusion injury. Several representative natural compounds, including calycosin 7-O-beta-D-glucoside, baicalin, Momordica charantia polysaccharide (MCP), chlorogenic acid, lutein and lycopene, have shown potential for targeting the RNS/Cav-1/MMP signaling pathway to protect the brain in ischemic stroke. Therefore, the RNS/Cav-1/MMP pathway is an important therapeutic target in ischemic stroke treatment.

PMID- 29595197 TI - Antimicrobial action of the cationic peptide, chrysophsin-3: a coarse-grained molecular dynamics study. AB - Antimicrobial peptides (AMPs) are small cationic proteins that are able to destabilize a lipid bilayer structure through one or more modes of action. In this study, we investigate the processes of peptide aggregation and pore formation in lipid bilayers and vesicles by the highly cationic AMP, Chrysophsin 3 (chrys-3), using coarse-grained molecular dynamics (CG-MD) simulations and potential of mean force calculations. We study long 50 MUs simulations of chrys-3 at different concentrations, both at the surface of dipalmitoylphosphatidylcholine (DPPC) and palmitoyloleoylphosphatidylcholine (POPC) bilayers, and also interacting within the interior of the lipid membrane. We show that aggregation of peptides at the surface, leads to pronounced deformation of lipid bilayers, leading in turn to lipid protrusions for peptide : ligand ratios > 1 : 12. In addition, aggregation of chrys-3 peptides within the centre of a lipid bilayer leads to spontaneous formation of pores and aggregates. Both mechanisms of interaction are consistent with previously reported experimental data for chrys-3. Similar results are observed also in POPC vesicles and mixed lipid bilayers composed of the zwitterionic lipid palmitoyloleoylphosphatidylethanolamine (POPE) and the negatively charged lipid palmitoyloleoylphosphatidylglycerol (POPG). The latter are employed as models of the bacterial membrane of Escherichia coli.

AB - Nanostructured metal alloys show great promise as replacement materials for graphite anodes, and could improve the energy and power density of present-day lithium-ion batteries (LIBs). Herein, we report a facile colloidal synthesis of CoSn2 and FeSn2 nanocrystals (NCs) via the reaction of Co or Fe NCs and SnCl2 in oleylamine under reducing conditions. Among our pure Sn NCs and mixtures of Co or Fe and Sn NCs, monodisperse CoSn2 nanoalloys showed considerably improved cycling stability. In particular, CoSn2 delivered a stable average capacity of 650 mA h g 1 for 5000 cycles at a high current density of 1984 mA g-1, which is among the highest reported cycling stabilities for Sn-based anode materials. PMID- 29595200 TI - Hyperpolarized long-lived nuclear spin states in monodeuterated methyl groups. AB - Monodeuterated methyl groups may support a long-lived nuclear spin state, with a relaxation time exceeding the conventional spin-lattice relaxation time T1. Dissolution-DNP (dynamic nuclear polarization) may be used to hyperpolarize such a long-lived spin state. This is demonstrated for the CH2D groups of a piperidine derivative. The polarized sample is manipulated in the ambient magnetic field of the laboratory, without destruction of the hyperpolarized singlet order. Strongly enhanced CH2D signals are observed more than one minute after dissolution, even in the presence of paramagnetic radicals, by which time the NMR signal from the hyperpolarized proton magnetization has completely disappeared.

AB - Advances in acetylated protein-protein/DNA interactions depend on the development of a novel NMR (nuclear magnetic resonance) probe to study the conformational changes of acetylated proteins. However, the method for detecting the acetylated protein conformation is underdeveloped. Herein, an acetyllysine mimic has been exploited for detecting the conformational changes of acetylated p53-protein/DNA interactions by genetic code expansion and 19F NMR. This 19F NMR probe shows high structural similarity to acetyllysine and could not be deacetylated by sirtuin deacetylase in vitro/vivo. Moreover, acetylation of p53 K164 is reported to be deacetylated by SIRT2 for the first time. PMID- 29595202 TI - Mining legacy across a wetland landscape: high mercury in Upper Peninsula (Michigan) rivers, lakes, and fish. AB - A geographic enigma is that present-day atmospheric deposition of mercury in the Upper Peninsula of Michigan is low (48%) and that regional industrial emissions have declined substantially (ca. 81% reduction) relative to downstate. Mercury levels should be declining. However, state (MDEQ) surveys of rivers and lakes revealed elevated total mercury (THg) in Upper Peninsula waters and sediment relative to downstate. Moreover, Western Upper Peninsula (WUP) fish possess higher methyl mercury (MeHg) levels than Northern Lower Peninsula (NLP) fish. A contributing explanation for elevated THg loading is that a century ago the Upper Peninsula was a major industrial region, centered on mining. Many regional ores (silver, copper, zinc, massive sulfides) contain mercury in part per million concentrations. Copper smelters and iron furnace-taconite operations broadcast mercury almost continuously for 140 years, whereas mills discharged tailings and old mine shafts leaked contaminated water. We show that mercury emissions from copper and iron operations were substantial (60-650 kg per year) and dispersed over relatively large areas. Moreover, lake sediments in the vicinity of mining operations have higher THg concentrations. Sediment profiles from the Keweenaw Waterway show that THg accumulation increased 50- to 400-fold above modern-day atmospheric deposition levels during active mining and smelting operations, with lingering MeHg effects. High MeHg concentrations are geographically correlated with low pH and dissolved organic carbon (DOC), a consequence of biogeochemical cycling in wetlands, characteristic of the Upper Peninsula. DOC can mobilize metals and elevate MeHg concentrations. We argue that mercury loading from mining is historically superimposed upon strong regional wetland effects, producing a combined elevation of both THg and MeHg in the Western Upper Peninsula.

PMID- 29595204 TI - Three-dimensional carbon network confined antimony nanoparticle anodes for high capacity K-ion batteries. AB - Antimony (Sb) represents a promising anode for K-ion batteries (KIBs) due to its high theoretical capacity and suitable working voltage. However, the large volume change that occurs in the potassiation/depotassiation process can lead to severe capacity fading. Herein, we report a high-capacity anode material by in situ confining Sb nanoparticles in a three-dimensional carbon framework (3D SbNPs@C) via a template-assisted freeze-drying treatment and subsequent carbothermic reduction. The as-prepared 3D SbNPs@C hybrid material delivers high reversible capacity and good cycling stability when used as the anode for KIBs. Furthermore, cyclic voltammetry and in situ X-ray diffraction analysis were performed to reveal the intrinsic mechanism of a K-Sb alloying reaction. Therefore, this work is of great importance to understand the electrochemical process of the Sb-based alloying reaction and will pave the way for the exploration of high performance KIB anode materials.

AB - The ability of cells to navigate through the extracellular matrix, a network of biopolymers, is controlled by an interplay of cellular activity and mechanical network properties. Synthetic hydrogels with highly tuneable compositions and elastic properties are convenient model systems for the investigation of cell migration in 3D polymer networks. To study the impact of macroscopic deformations on single cell migration, we present a novel method to introduce uniaxial strain in matrices by microstructuring photo-polymerizable hydrogel strips with embedded cells in a channel slide. We find that such confined swelling results in a strained matrix in which cells exhibit an anisotropic migration response parallel to the strain direction. Surprisingly, however, the anisotropy of migration reaches a maximum at intermediate strain levels and decreases strongly at higher strains. We account for this non-monotonic response in the migration anisotropy with a computational model, in which we describe a cell performing durotactic and proteolytic migration in a deformable elastic meshwork. Our simulations reveal that the macroscopically applied strain induces a local geometric anisotropic stiffening of the matrix. This local anisotropic stiffening acts as a guidance cue for directed cell migration, resulting in a non-monotonic dependence on strain, as observed in our experiments. Our findings provide a mechanism for mechanical guidance that connects network properties on the cellular scale to cell migration behaviour.

AB - We demonstrate a concept to produce deposits of polymer in the form of particles by inkjet printing an emulsion in which the discrete phase evaporates preferentially. An oil/water emulsion with polymer contained inside the oil phase is used as ink for printing. Circular deposits of spherical polymer particles with uniform thickness are obtained. The effects of the hydrophobicity of substrates and the physical properties of the oil on the morphology of the deposits are explored. The deposit of aggregated polymeric particles can be transformed into a uniform film by annealing if required. This strategy for the patterning of polymer materials in the form of either particles or a film works for mixtures of polymers and functional cargoes.

AB - We demonstrate the pulsed voltage tunable multileveled resistive switching (RS) across a promising transparent energy material of (C4H9NH3)2PbBr4. The X-ray diffraction and scanning electron microscopy results confirm the growth of (001) plane-orientated nanostructures of (C4H9NH3)2PbBr4 with an average size of ~360 nm. The device depicts optical transmittance higher than 70% in the visible region and efficient absorbance in the ultraviolet region. The current-voltage measurement shows the bipolar RS. In addition, depending on the magnitude of applied electric pulse, the current across the device can be flipped in four different levels, which remain stable for long time, indicating multimode RS. Further, the current across the device increases gradually by applying continuous pulses, similar to the biological synapses. The observed results are attributed to the electric field-induced ionic migration across the (C4H9NH3)2PbBr4. The existing study should open a new avenue to apply this promising energy material of perovskite for multifunctional advanced devices.

AB - In this work, garnet-framework Li3Nd3W2O12 as a novel insertion-type anode material has been prepared via a facile sol-gel method and examined as a lithium container for lithium ion batteries (LIBs). Li3Nd3W2O12 shows a charge capacity of 225 mA h g-1 at 50 mA g-1, and with the current density increasing up to 500 mA g-1, the charge capacity can still be maintained at 186 mA h g-1. After cycling at 500 mA g-1 for 500 cycles, Li3Nd3W2O12 retains about 85% of its first charge capacity changed from 190.2 to 161 mA h g-1. Furthermore, in situ X-ray diffraction technique is adopted for the understanding of the insertion/extraction mechanism of Li3Nd3W2O12. The full-cell configuration LiFePO4/Li3Nd3W2O12 is also assembled to evaluate the potential of Li3Nd3W2O12 for practical application. These results show that Li3Nd3W2O12 is such a promising anode material for LIBs with excellent electrochemical performance and stable structure.

AB - In this study, bortezomib (BTZ, a cytotoxic water-insoluble anticancer drug) was encapsulated in micellar nanoparticles having a catechol-functionalized polycarbonate core through a pH-sensitive covalent bond between phenylboronic acid (PBA) in BTZ and catechol, and these drug-loaded micelles were incorporated into hydrogels to form micelle/hydrogel composites. A series of injectable, biodegradable hydrogels with readily tunable mechanical properties were formed and optimized for sustained delivery of the BTZ-loaded micelles through ionic coacervation between PBA-functionalized polycarbonate/poly(ethylene glycol) (PEG) "ABA" triblock copolymer and a cationic one having guanidinium- or thiouronium functionalized polycarbonate as "A" block. An in vitro release study showed the pH dependence in BTZ release. At pH 7.4, the BTZ release from the micelle/hydrogel composite remained low at 7%, whereas in an acidic environment, ~85% of BTZ was released gradually over 9 days. In vivo studies performed in a multiple myeloma MM.1S xenograft mouse model showed that the tumor progression of mice treated with BTZ-loaded micelle solution was similar to that of the control group, whereas those treated with the BTZ-loaded micelle/hydrogel composite resulted in significant delay in the tumor progression. The results demonstrate that this hydrogel has great potential for use in subcutaneous and sustained delivery of drug-loaded micelles with superior therapeutic efficacy. PMID- 29595245 TI - Stimuli-Responsive DNA Microcapsules for SERS Sensing of Trace MicroRNA. AB - In this work, one stimuli-responsive DNA microcapsule was designed to combine duplex-specific nuclease (DSN) amplification strategy and surface-enhanced Raman spectroscopy (SERS) technology for sensitive detection of microRNA 155 (miRNA 155). First, toluidine blue (TB) as Raman dye and CaCO3 as core templates co precipitated to form TB@CaCO3 composite. Then, DNA networks were layer by layer constructed with oligonucleotide layers cross-linked by linker ssDNA L to lock TB@CaCO3 inside. In the presence of ethylenediaminetetraacetic acid, the core CaCO3 would be dissolved to form TB-loading DNA microcapsule. With target miRNA 155-induced DSN signal amplification, a large amount of simulative target ssDNA D was obtained, which can completely complement with the linker L on the DNA networks, destroying the microcapsule to release TB and obtain a strong Raman signal. So by this smart design, a SERS platform was fabricated on the basis of the stimuli-responsive DNA microcapsule to detect miRNA 155 from 1 fM to 10 nM with a detection limit of 0.67 fM. In the present study, the programmable property and rapid response speed of DNA microcapsule, which helped in fabrication of a new potential biosensing technology for miRNA detection that is anticipated to be applied for clinical diagnosis. PMID- 29595246 TI - Reduction-Responsive Codelivery System Based on a Metal-Organic Framework for Eliciting Potent Cellular Immune Response. AB - Utilizing nanoparticles to deliver subunit vaccines can be viewed as a promising strategy for enhancing the immune response, especially with regard to cellular immunity to fight against infectious viruses and malignant cancer. Nevertheless, its applications are still far from practicality because of some limitations such as high cost, non-biocompatibility, non-biodegradability, and the inefficient stimulation of cytotoxic T lymphocyte (CTL) response. In this study, we use metal organic framework (MOF) MIL-101-Fe-NH2 nanoparticles as carriers to fabricate an innovative reduction-responsive antigen delivery system for cotransporting the antigen model ovalbumin (OVA) and an immune adjuvant, unmethylated cytosine phosphate-guanine (CpG) oligonucleotide. In vitro cellular tests show that the MOF nanoparticles can not only greatly improve the uptake of OVA by the antigen presenting cells but also smartly deliver both OVA and CpG into the same cell. By feat of the reductively controllable release of OVA and the promoting function of CpG, the delivery system can elicit strong cellular immunity and CTL response in mice. Moreover, the increased frequencies of effector memory T cells inspired by the delivery system indicate that it can induce a potent immune memory response. These results demonstrate that MOF nanoparticles are excellent vehicles for codelivering antigen and immune adjuvant and may find wider applications in biomedical fields.

The RuBPZ2+ displayed photoluminescence (PL) at room temperature with a lifetime of 1.75 MUs. The addition of bromide to a RuBPZ2+ acetone solution led to significant PL quenching and Stern-Volmer plots showed upward curvature. Time-resolved PL measurements identified two excited state quenching pathways, static and dynamic, which were operative toward [RuBPZ2+, Br-]+ and free RuBPZ2+, respectively. The single ion pair [RuBPZ2+, Br-]+* had a lifetime of 45 +/- 5 ns, consistent with an electron transfer rate constant, ket = (2.2 +/- 0.3) * 107 s-1. In contrast, RuBPZ2+* was dynamically quenched by bromide with a quenching rate constant, kq = (8.1 +/- 0.1) * 1010 M-1 s-1. Nanosecond transient absorption revealed that both the static and dynamic pathways yielded RuBPZ+ and Br2*- products that underwent recombination to regenerate the ground state with a second-order rate constant, kcr = (2.3 +/- 0.5) * 1010 M-1 s-1. Kinetic analysis revealed that RuBPZ+ was a primary photoproduct, while Br2*- was secondary product formed by the reaction of a Br* with Br-, k = (1.1 +/- 0.2) * 1010 M-1 s-1. Marcus theory afforded an estimate of the formal reduction potential for E0(Br*/-) in acetone, 1.42 V vs NHE. A 1H NMR analysis indicated that the ion-paired bromide was preferentially situated close to the RuII center. Prolonged steady state photolysis of RuBPZ2+ and bromide yielded two ligand-substituted photoproducts, cis- and trans Ru(deeb)(bpz)Br2. A photochemical intermediate, proposed to be [Ru(deeb)(bpz)(kappa1-bpz)(Br)]+, was found to absorb a second photon to yield cis- and trans-Ru(deeb)(bpz)Br2 photoproducts.

AB - On Svalbard, Arctic Norway, an unconventional siliciclastic reservoir, relying on (micro)fractures for enhanced fluid flow in a low-permeable system, is investigated as a potential CO2 sequestration site. The fractures' properties at depth are, however, poorly understood. High resolution X-ray computed tomography (micro-CT) imaging allows one to visualize such geomaterials at reservoir conditions. We investigated reservoir samples from the De Geerdalen Formation on Svalbard to understand the influence of fracture closure on the reservoir fluid flow behavior. Small rock plugs were brought to reservoir conditions, while permeability was measured through them during micro-CT imaging. Local fracture apertures were quantified down to a few micrometers wide. The permeability measurements were complemented with fracture permeability simulations based on the obtained micro-CT images. The relationship between fracture permeability and the imposed confining pressure was determined and linked to the fracture apertures. The investigated fractures closed due to the increased confining pressure, with apertures reducing to approximately 40% of their original size as the confining pressure increased from 1 to 10 MPa. This coincides with a permeability drop of more than 90%. Despite their closure, fluid flow is still controlled by the fractures at pressure conditions similar to those at the proposed storage depth of 800-1000 m.

AB - We have discovered an unexpected correlation between the operational temperature of the brain and cognitive abilities across a wide variety of animal species. This correlation is extracted from available data in the literature of the temperature range Delta T at which an animal's brain can operate and its encephalization quotient EQ, which can be used as a proxy for cognitive ability. In particular, we found a power-law dependence between Delta T and EQ. These data support the theory that the brain behaves as a critical system where temperature is one of the critical parameters, tuning the performance of the neural network.

AB - Adsorption-induced change of carrier density is presently dominating inorganic semiconductor gas sensing, which is usually operated at a high temperature. Besides carrier density, other carrier characteristics might also play a critical role in gas sensing. Here, we show that carrier mobility can be an efficient parameter to dominate gas sensing, by which room-temperature gas sensing of inorganic semiconductors is realized via a carrier mobility-dominated gas-sensing (CMDGS) mode. To demonstrate CMDGS, we design and prepare a gas sensor based on a regular array of SnO2 nanorods on a bottom film. It is found that the key for determining the gas-sensing mode is adjusting the length of the arrayed nanorods. With the change in the nanorod length from 340 to 40 nm, the gas-sensing behavior changes from the conventional carrier-density mode to a complete carrier-mobility mode. Moreover, compared to the carrier density-dominating gas sensing, the proposed CMDGS mode enhances the sensor sensitivity. CMDGS proves to be an emerging gas-sensing mode for designing inorganic semiconductor gas sensors with high performances at room temperature.

AB - The elasticity of a cell is one of the most critical measures of the difference between cancerous cells and healthy cells: cancer cells tend to be softer than healthy cells, and highly invasive cells tend to be more elastic than less aggressive cells. In this work, we present the novel "bottom-up" cell force spectroscopy method for the biophysical characterization of cancer cells, in which an atomic force microscopy (AFM) tip approach from the backside of a net shaped culture substrate exposing the basolateral cell membrane drum, and compare it with the conventional "top-down" AFM measurements. We used two different human pancreatic carcinoma cell lines, PaTu8988S and PaTu8988T. Our bottom-up AFM tip approach provided a more statistically synchronized distribution of the measured elastic moduli of the cells, demonstrating its superior applicability for the clinical use of force spectroscopy, which is not attainable with the conventional top-down AFM approach.

PMID- 29595253 TI - Magnetic Nanozyme-Linked Immunosorbent Assay for Ultrasensitive Influenza A Virus Detection. AB - Rapid and sensitive detection of influenza virus is of soaring importance to prevent further spread of infections and adequate clinical treatment. Herein, an ultrasensitive colorimetric assay called magnetic nano(e)zyme-linked immunosorbent assay (MagLISA) is suggested, in which silica-shelled magnetic nanobeads (MagNBs) and gold nanoparticles are combined to monitor influenza A virus up to femtogram per milliliter concentration. Two essential strategies for ultrasensitive sensing are designed, i.e., facile target separation by MagNBs and signal amplification by the enzymelike activity of gold nanozymes (AuNZs). The enzymelike activity was experimentally and computationally evaluated, where the catalyticity of AuNZ was tremendously stronger than that of normal biological enzymes. In the spiked test, a straightforward linearity was presented in the range of 5.0 * 10-15-5.0 * 10-6g.mL-1 in detecting the influenza virus A (New Caledonia/20/1999) (H1N1). The detection limit is up to 5.0 * 10-12 g.mL-1 only by human eyes, as well as up to 44.2 * 10-15 g.mL-1 by a microplate reader, which is the lowest record to monitor influenza virus using enzyme-linked immunosorbent assay-based technology as far as we know. Clinically isolated human serum samples were successfully observed at the detection limit of 2.6 PFU.mL-1. This novel MagLISA demonstrates, therefore, a robust sensing platform possessing the advances of fathomable sample separation, enrichment, ultrasensitive readout, and anti-interference ability may reduce the spread of influenza virus and provide immediate clinical treatment.

AB - In order to extend the physical length of hole delocalization in a molecular wire, chromophores of increasing size are often desired. However, the effect of size on the efficacy and mechanism of hole delocalization remains elusive. Here, we employ a model set of biaryls to show that with increasing chromophore size, the mechanism of steady-state hole distribution switches from static delocalization in biaryls with smaller chromophores to dynamic hopping, as exemplified in the largest system, tBuHBC2 (i.e., "superbiphenyl"), which displays a vanishingly small electronic coupling. This important finding is analyzed with the aid of Huckel molecular orbital and Marcus-Hush theories. Our findings will enable the rational design of the novel molecular wires with length invariant redox/optical properties suitable for long-range charge transfer. PMID- 29595255 TI - Linking Thermodynamics to Pollutant Reduction Kinetics by Fe2+ Bound to Iron Oxides. AB - Numerous studies have reported that pollutant reduction rates by ferrous iron (Fe2+) are substantially enhanced in the presence of an iron (oxyhydr)oxide mineral. Developing a thermodynamic framework to explain this phenomenon has been historically difficult due to challenges in quantifying reduction potential ( EH) values for oxide-bound Fe2+ species. Recently, our group demonstrated that EH values for hematite- and goethite-bound Fe2+ can be accurately calculated using Gibbs free energy of formation values. Here, we tested if calculated EH values for oxide-bound Fe2+ could be used to develop a free energy relationship capable of describing variations in reduction rate constants of substituted nitrobenzenes, a class of model pollutants that contain reducible aromatic nitro groups, using data collected here and compiled from the literature. All the data could be described by a single linear relationship between the logarithms of the surface-area-normalized rate constant ( kSA) values and EH and pH values [log( kSA) = - EH/0.059 V - pH + 3.42]. This framework provides mechanistic insights into how the thermodynamic favorability of electron transfer from oxide-bound Fe2+ relates to redox reaction kinetics. PMID- 29595257 TI - Azoreductase and Target Simultaneously Activated Fluorescent Monitoring for Cytochrome c Release under Hypoxia. AB - Hypoxia-induced cell apoptosis is closely related to degenerative diseases, autoimmune disorders, and tumor disease. In the process of apoptosis, the release of cytochrome c (Cyt c) is deemed to be a critical factor of the intrinsic pathway. Strategies for tracking Cyt c release in living cells based on the subcellular localization have been proposed recently. However, they are inherently lack of specificity for distinguishing the release of Cyt c in apoptotic process induced by hypoxia from other stimulus. In this paper, an azoreductase and target simultaneously activated fluorescent aptameric nanosensor integrating gold nanoparticles (AuNPs) and Cyt c-targeted aptamer-consisted double-stranded DNA hybridization complex (DSDHC) was proposed. It is worth noting that the employment of azobenzene moiety labeled on the DSDHC first ensured the aptameric nanosensor could be conjugated to the surface of AuNPs and then specifically reduced by hypoxia-related azoreductase. Upon Cyt c released from mitochondrion under hypoxia, the competitive displacement of Cyt c subsequently activated the fluorescence of the aptameric nanosensor and the fluorescence enhancement depended principally on the content of Cyt c release. Inspired by this, a new strategy for quantitative analysis and in situ imaging of Cyt c under hypoxic condition was proposed. The high spatial resolution monitoring of the dynamics of Cyt c release under hypoxia will offer a potentially rich opportunity to understand the apoptotic mechanism under hypoxic conditions, thus further facilitating risk assessment and risk reduction for hypoxic environments.

AB - This study investigated the effects of dietary l-arginine (Arg) and N carbamylglutamate (NCG) supplementation on intestinal integrity, immune function, and oxidative status in intrauterine-growth-retarded (IUGR) suckling lambs. A total of 48 newborn Hu lambs of normal birth weight (CON) and IUGR were allocated randomly into four groups of 12 animals each: CON, IUGR, IUGR + 1% Arg, or IUGR + 0.1% NCG. All lambs were raised for a period of 21 days from 7 to 28 days after birth. The Arg or NCG group exhibited improved ( p < 0.05) final body weights compared to that of the IUGR group. In comparison to the IUGR lambs, the apoptotic percentage was lower ( p < 0.05) in the ileum of IUGR lambs supplemented with Arg and NCG. In addition, in comparison to IUGR, the concentrations of protein carbonyl and malondialdehyde were lower ( p < 0.05) and the reduced glutathione (GSH) concentration and ratio of GSH/oxidized glutathione were greater ( p < 0.05) in the jejunum, duodenum, and ileum of IUGR + 1% Arg or 0.1% NCG lambs. In comparison to the IUGR group, the mRNA abundance of myeloid differentiation factor 88, toll-like receptor 9, toll-like receptor 4, interleukin 6, and fuclear factor-kappaB was lower ( p < 0.05) and the mRNA abundance of superoxide dismutase 1, B-cell lymphoma/leukaemia 2, zonula occludens-1 (ZO-1), and occludin was greater in the ileum of the IUGR lambs supplemented with Arg or NCG. Furthermore, the protein abundance of ZO-1 and claudin-1 in the ileum was greater ( p < 0.05) in the IUGR + 1% Arg or 0.1% NCG lambs. The results show that Arg or NCG supplementation improves the growth, intestinal integrity, immune function, and oxidative status in IUGR Hu suckling lambs.

AB - Dioxygen activation at nickel complexes is much less studied than for the biologically more relevant iron or copper systems but promises new reactivity patterns because of the distinct coordination chemistry of nickel. Here we report that a pyrazolate-based dinickel(II) dihydride complex [KL(Ni-H)2] (1a) smoothly reacts with O2 via reductive H2 elimination to give the MU-1,2-peroxo dinickel(II) complex [KLNi2(O2)] (2a) and, after treatment with dibenzo[18]-crown 6, the separated ion pair [K(DB18C6)][LNi2(O2)] (2b); these are the first MU-1,2 peroxo dinickel intermediates to be characterized by X-ray diffraction. In 2a, the K+ is found side-on associated with the peroxo unit, revealing a pronounced weaking of the O-O bond: d(O-O) = 1.482(2) A in 2a versus 1.465(2) in 2b; nu(O-O) = 720 cm-1 in 2a versus 755 cm-1 in 2b. Reaction of 1a (or 2a/2b) with an excess of O2 cleanly leads to [LNi2(O2)] (3), which was shown by X-ray crystallography ( d(O-O) = 1.326(2) A), electron paramagnetic resonance and Raman spectroscopy (nu(O-O) = 1007 cm-1), magnetic measurements, and density functional theory calculations to feature two low-spin d8 nickel(II) ions and a genuine MU-1,2 superoxo ligand with the unpaired electron in the out-of-plane pi*O-O orbital. These MU-1,2-superoxo and MU-1,2-peroxo species, all containing the O2-derived unit within the cleft of the dinickel(II) core, can be reversibly interconverted chemically and also electrochemically at very low potential ( E1/2 = -1.22 V vs Fc/Fc+). Initial reactivity studies indicate that protonation of 2a, or reaction of 3 with TEMPO-H, ultimately gives the MU-hydroxo dinickel(II) complex [LNi2(MU OH)] (4). This work provides an entire new series of closely related and unusually rugged Ni2/O2 intermediates, avoiding the use of unstable nickel(I) precursors but storing the redox equivalents for reductive O2-binding in nickel(II) hydride bonds.

AB - Molecules capable of monitoring receptor protein-tyrosine kinase expression could potentially serve as useful tools for cancer diagnosis due to the overexpression of tyrosine kinases during tumor growth and metastasis. In this work, a conformationally induced "off-on" tyrosine kinase cell membrane fluorescent sensor (SP1) was designed and evaluated for the detection and imaging of receptor protein-tyrosine kinases in vivo and in vitro. SP1 consists of sunitinib and pyrene linked via hexamethylenediamine and displays quenched fluorescence as a dimer. The fluorescence of SP1 is restored in the presence of receptor protein tyrosine kinases upon strong interaction with SP1 at the target terminal. The unique signal response mechanism enables SP1 use for fluorescence microscopy imaging of receptor protein-tyrosine kinases in the cell membranes of living cells, allowing for the rapid differentiation of cancer cells from normal cells. SP1 can be used to visualize the chick embryo chorioallantoic membrane and mouse model tumors, suggesting its possible application for early cancer diagnosis.

AB - The first Pd-catalyzed multicomponent reaction of aryl iodides, alkenyl bromides, and strained alkenes has been developed, which allowed us to synthesize a variety of multisubsituted olefins in yields of 45-96% with excellent stereoselectivity. The configuration of the product was controlled by the configuration of the alkenyl bromides. Moreover, this practical methodology employing readily available substrates was found to be tolerant to a wide range of functional groups. Fifty six examples of highly stereoselective tri- or tetrasubstituted olefins have been successfully synthesized via this methodology. Most of the synthesized tetrasubstituted olefins are good aggregation-induced emission (AIE) luminogens.

AB - A biomimetic approach to the formation of titania (TiO2) nanostructures is desirable because of the mild conditions required in this form of production. We have identified a series of serine-lysine peptides as candidates for the biomimetic production of TiO2 nanostructures. We have assayed these peptides for TiO2-precipitating activity upon exposure to titanium bis(ammonium lactato)dihydroxide and have characterized the resulting coprecipitates using scanning electron microscopy. A subset of these assayed peptides efficiently facilitates the production of TiO2 nanospheres. Here, we investigate the process of TiO2 nanosphere formation mediated by the S-K peptides KSSKK- and SKSK3SKS using one-dimensional and two-dimensional solid-state NMR (ssNMR) on peptide samples with uniformly 13C-enriched residues. ssNMR is used to assign 13C chemical shifts (CSs) site-specifically in each free peptide and TiO2-embedded peptide, which are used to derive secondary structures in the neat and TiO2 coprecipitated states. The backbone 13C CSs are used to assess secondary structural changes undergone during the coprecipitation process. Side-chain 13C CS changes are analyzed with density functional theory calculations and used to determine side-chain conformational changes that occur upon coprecipitation with TiO2 and to determine surface orientation of lysine side chains in TiO2-peptide composites.

For successful application, a robust and scalable, yet flexible, route to non-natural amino acids is required.

The identities of these hemicages were characterized using 1H NMR, 1H-1H COSY, DOSY, and ESI-TWIM MS. Free rotation of the ferrocene structural units in the ligands affords an adaptable directionality, which is essential for the construction of these hemicages. Encapsulation of adamantane by C2 indicates the presence of a well defined inner cavity as the binding pocket. PMID- 29595265 TI - Conformational Properties of Aromatic Oligoamides Bearing Pyrrole Rings. AB - N-Alkylbenzanilides generally exist in cis conformation both in the crystalline state and in various solvents, and this cis conformational preference can be utilized to construct dynamic helical oligoamides. Here, we synthesized the pyrrole-containing amides 2-5 and their oligomers 6-8 and examined their conformations in the crystalline state and in solution. All the N-methylated amides showed cis conformational preference in solution, but the ratio of the cis isomer was decreased when the amide bond was attached at the 4-position of the pyrrole ring, probably because the destabilization of the trans conformer due to electronic repulsion between the pyrrole pi electrons and the amide carbonyl lone pair electrons is reduced due to the small torsion angle between the 5-membered N pyrrole and the amide bond. In the crystalline state, N-methylated amides showed cis structure, except for compound 5, and cis conformational preference was observed for the pyrrole amides. The CD spectra of oligoamides 15-18 bearing chiral N-substituents were consistent with the presence of dynamic and well defined chiral foldamers, which were structurally distinct from N-alkylated poly( p-benzamide)s 1.

AB - Here, we propose a simple mechanoresponsive system on patterned soft surfaces to manipulate both anisotropy and orientation of liquid wetting. On the poly(dimethylsiloxane) embedding line patterned structures, additional topographies, such as wrinkles and cracks, can be provided by applying compressive and tensile stress, respectively. This tunable hierarchy of structures with the different scales and directions of lines, wrinkles, and cracks allow the mechanoresponsive control of anisotropic wetting in a single platform. In addition, the wetting behavior on those surfaces is precisely investigated based on the concept of critical contact angle to overcome the ridges in a step flow. PMID- 29595267 TI - Tetrahydroquinoline Ring as a Versatile Bioisostere of Tetralin for Melatonin Receptor Ligands. AB - A new family of melatonin receptor ligands, characterized by a tetrahydroquinoline (THQ) scaffold carrying an amide chain in position 3, was devised as conformationally constrained analogs of flexible N-anilinoethylamides previously developed. Molecular superposition models allowed to identify the patterns of substitution conferring high receptor binding affinity and to support the THQ ring as a suitable scaffold for the preparation of melatonin ligands. The biological activity of 3-acylamino-THQs was compared with that of the corresponding tetralin derivatives. The THQ ring proved to be a versatile scaffold for easy feasible MT1 and MT2 ligands, which resulted as more polar bioisosteres of their tetralin analogs. Potent partial agonists, with subnanomolar binding affinity for the MT2 receptor, were obtained, and a new series of THQ derivatives is presented. The putative binding mode of potent THQs and tetralines was discussed on the basis of their conformational equilibria as inferred from molecular dynamics simulations and experimental NMR data. PMID- 29595268 TI - Halide Composition Controls Electron-Hole Recombination in Cesium-Lead Halide Perovskite Quantum Dots: A Time Domain Ab Initio Study. AB - We demonstrate that halide content strongly affects nonradiative electron-hole recombination in all-inorganic perovskite quantum dots (QDs). Using time domain density functional theory and nonadiabatic molecular dynamics, we show that replacing half of the bromines with iodines in a CsPbBr3 QD extends the charge carrier lifetime by a factor of 5, while complete replacement extends the lifetime by a factor of 8. Doping with iodines decreases the nonadiabatic charge phonon coupling because iodines are heavier and slower than bromines and because the overlap between the electron and hole wave functions is reduced. In general, the nonradiative electron-hole recombination proceeds slowly, on a nanosecond time scale, due to small sub-1 meV nonadiabatic coupling and short sub-10 fs coherence times. The obtained recombination times and their dependence on the halogen content show excellent agreement with experiments. Our study suggests that the power conversion efficiencies of solar cells can be controlled by changing the halide composition in all-inorganic perovskite QDs.

Here, we propose a three-dimensional metal-dielectric parabolic antenna surrounding an individual quantum dot as a source of collimated single photons, which can then be easily extracted and manipulated. Our fabrication method relies on a single optically induced polymerization step once the selected emitter has been localized by confocal microscopy. Compared to conventional nanoantennas, our geometry does not require near-field coupling, and it is, therefore, very robust against misalignment issues and minimally affected by absorption in the metal. The parabolic antenna provides one of the largest reported experimental directivities ( D = 106) and the lowest beam divergences (Theta1/2 = 13.5 degrees ) and a broadband operation over all of the visible and near-infrared range together with extraction efficiency of more than 96%, offering a practical advantage for quantum technological applications.

This article deals with the serious and mostly acute impairment of cardiovascular, respiratory, renal, gastrointestinal, hematopoietic or nervous systems, briefly discusses the acute pregnancy complication and summarizes the basic therapeutic option.

PMID- 29595274 TI - [Chronic pain therapy in inflammatory rheumatic diseases]. AB - Chronic pain is a common health problem related to most of inflammatory rheumatic disorders. It is pain that has persisted for at least 3 month and cannot be fully relieved by standard pain medication. 40-60 % of patients do not have adequate relief of their pain. Paramount in the management of chronic pain patients is assessment of the pain and its impact on physical and psychosocial functioning. Multidisciplinary and multimodal approach is of vital importance. Non-steroidal anti-rheumatic drugs (NSA) have been used mainly due to their strong analgesic effect, especially in the treatment of acute pain as well as their anti inflammatory effect in the treatment of chronic i pain. Long-term systemic administration of NSA may be associated with a number of serious side effects, which significantly limit NSA use in long term therapy. Due to opiophobia, opioids are insufficiently used treatment modality. Knowledge about pain and its management, as well as an awareness of barriers to effective pain therapy, are important not only for pain specialists but also primary care physicians.Key words: chronic pain - non-steroidal antirheumatic drugs - opiophobia - opioids - pain assessment - paracetamol - rheumatoid arthritis. PMID- 29595275 TI - [Rheumatoid arthritis]. AB - Rheumatoid arthritis is an autoimmune disease manifested by a persistent inflammation of synovial joints, bone destruction, loss of cartilage and increased risk of cardiovascular and other intercurrent diseases. The treatment of rheumatoid arthritis should be based on the strategy of treat to target therapy which is achieving remission, in some cases low activity of the disease. Essential to the treat to target therapy are more frequent checkups and optimization of treatment based on disease activity. Methotrexate continues to be the essential medicine from the group of disease modifying antirheumatic drugs for rheumatoid arthritis treatment. At the start are frequently added glucocorticoids. If the effect is insufficient, biological therapy or use of targeted synthetic drugs can be considered. In this overview, the author will focus on epidemiology and risk factors, pathophysiology and in particular on the diagnostics, evaluation of activity and treatment of rheumatoid arthritis.Key words: diagnostics - disease activity - rheumatoid arthritis - treatment. PMID- 29595276 TI - [Axial spondyloarthritis]. AB - Axial spondyloarthritis (axSpA) is a common name for the non-radiographic form of the disease and radiographic axial spondyloarthritis, known as ankylosing spondylitis (AS). The disease is typically manifested at a young age, characterized by affection of axial skeleton, and in the most severe form can lead to complete ankylosis of the spine. Etiology of diseases have not yet been clarified, however, the genetic background, especially the binding to HLA-B27 antigen, is obvious. Clinical manifestations are dominated by chronic pain in the lower pain or buttocks that occurred in young age, in a large proportion of patients having the character of so-called inflammatory pain. In addition to the axial skeleton, axSpA there is also common affection of peripheral skeleton in the form of enthesitis, arthritis, and less often dactylitis. At present, enthesitis is considered as a hallmark of the entire spondyloarthritis group. Typical for axSpA is the frequent presence of extraskeletal manifestations in the form of uveitis, idiopathic intestinal inflammation and psoriasis. In the axSpA diagnosis, significant advances have been made in recent years in the field of imaging techniques. Magnetic resonance imaging can also identify the early stage of the disease before the development of structural lesions. Also, the newer concepts of the entire spondyloarthritis group, based on the 2009 ASAS (Assessment of SpondyloArthritis international Society) classification criteria, contributed to early diagnosis of the disease, and in particular to the underlying importance of association with HLA-B27 antigen and the presence of peripheral and non-articular manifestations. Non-steroidal anti-rheumatic drugs (NSAIDs) and TNFalpha blockers are effective axSpA therapy, which has been recently enhanced by interleukin 17 blockade (IL17).Key words: axial spondyloarthritis - biological treatment - enthesitis - extraarticular manifestations - magnetic resonance imaging - non-radiographic axial spondyloarthritis - sacroiliitis. PMID- 29595277 TI - [The role of magnetic resonance imaging in diagnostics of axial spondyloarthritis]. AB - Axial spondyloarthritis (SpA) is a chronic inflammatory rheumatic disorder that primary affects axial skeleton. It comprises wide spectrum of patients with immune mediated spine inflammation, from early, so called non-radiographic axial spondyloarthritis to clinically evident ankylosing spondylitis. Conventional radiography is still the cornerstone of diagnosis, evaluation and classification of SpA. However, it has limitations in early disease, because it can only depict the consequences of inflammation for its inability to visualize soft tissue abnormalities within bone marrow. Magnetic resonance imaging (MRI) is superior to conventional radiography in early disease through its ability to visualize active inflammatory changes in sacroiliac joints when the pelvic radiographs are normal or equivocal. MRI of sacroiliac joints is also included to the Assessment of Axial Spondyloarthritis (ASAS) classification criteria for axial SpA. For classification purposes positive definition of MRI sacroiliitis was proposed with the clear presence of subchondral bone marrow edema (osteitis), which does not cross anatomical borders and is usually present on more consecutive slides. The more intense the signal is on fluid sensitive MRI sequences; more likely it reflects active inflammation, because small focal bone marrow edema lesions may occur in patients with mechanical back pain. It may be associated with signs of structural damage such as erosions, which can enhance diagnostic utility of MRI in cases of not highly suggestive appearance of osteitis. Contrast-enhanced imaging is not useful for routine diagnostic evaluation. When MRI findings are not clear, an additional MRI of the spine can be performed, especially of the area with the most pronounced complaints. Evidence of bone marrow edema in three or more vertebral edges is considered as highly suggestive of axial SpA, especially in patients of younger age, when degenerative changes are expected to play minor role for differential diagnosis.Key words: ankylosing spondylitis - axial spondyloarthritis - magnetic resonance imaging (MRI) - sacroiliitis.

AB - Psoriatic arthritis (PsA) is a heterogeneous disease affecting, besides synovial joints, also the entheses, the soft tissues of the whole finger (dactylitis) and the axial skeleton. Currently the classification criteria CASPAR are used to diagnose PsA. In a large number of patients the disease leads to irreversible joint damage (X-ray, respectively clinical) which significantly reduces life quality and limits the patient in his/her everyday activities and also considerably limits their work capacity. There is evidence showing that early commencement of treatment and treat to target principle can significantly reduce this negative development. In recent time the knowledge of the disease pathogenesis has been extending and at the same time new drugs appear that act on the critical pathogenetic processes in a targeted way. These are biological drugs from the group of TNFalpha inhibitors and, most recently, also inhibitors of Th17 - IL17 pathway. Together with that is further specified the treatment strategy and the way of its monitoring. These new findings have led to the update of recommendations for the treatment and monitoring of psoriatic arthritis by the Czech Society for Rheumatology.Key words: biological drugs - conventional synthetic disease-modifying antirheumatic drugs - early treatment - psoriatic arthritis - targeted synthetic disease modifying drugs - treat to target. PMID- 29595279 TI - [Systemic sclerosis in 2017]. AB - Systemic sclerosis is classed as a diffuse (systemic) disease of connective tissue. It is a heterogeneous disease significantly shortening life expectancy. Its etiology is unknown. Pathogenetic interplay is assumed to involve a triad of pathological autoimmune inflammation, vasculopathy and fibrosis. Clinical manifestations can be classed based on the preponderant pathogenetic process. Vasculopathy is manifested by secondary Raynauds phenomenon with abnormal findings on the nailfold capillaroscopy, skin telangiectasias, gastric antral vascular ectasia, life threatening scleroderma renal crisis, digital ulcerations and prognostically severe pulmonary arterial hypertension. The treatment of vascular manifestations uses medicines with vasodilation effect. The manifestation of inflammation is accentuated by pleurisy, pericarditis, myositis, synovitis/arthritis and alveolitis. Finally, the manifestation of fibrosis predominates in association with dermatosclerosis, interstitial lung disease and fibrotic impairment of the gastrointestinal tract. Medicines with immunomodulatory or immunosupressive effects are used to affect the inflammation and fibrosis. Despite the aforementioned, there is still no universally effective treatment available. The pharmacological therapy of this disease is organ specific and symptomatic.Key words: capillaroscopy - digital ulcers - interstitial lung disease - pulmonary arterial hypertension - scleroderma renal crisis - systemic sclerosis. PMID- 29595280 TI - [Idiopathic inflammatory myopathies]. AB - Idiopathic inflammatory myopathies form a heterogeneous group of acquired inflammatory diseases afflicting striated muscles. The disease is frequently accompanied by systemic and organ involvement. Dermatomyositis, polymyositis, cancer associated myositis, immune mediated necrotizing myopathy, myositis in overlap syndromes, juvenile myositis and inclusion body myositis are the most frequently encountered subtypes. The basic manifestation is usually painless muscle weakness brought about by inflammation and by other immune changes at the impacted muscles. Enzymes of muscle origin and myoglobin are found elevated in the circulation. There are changes in electrical properties of muscle fibers detected by EMG. A majority of patients have autoantibodies against nuclear or cytoplasmic antigens in their serum. They are often very specific for these diseases and frequently found in association with particular clinical presentations. For some patients with dermatomyositis the increased incidence of cancer is significantly associated with anti-TIF1gamma and anti-NXP2 autoantibodies. Differential diagnostics of inflammatory myopathies is often difficult. Misdiagnosis for a non-inflammatory myopathy is not rare and therefore a very thorough diagnostic approach is necessary. Therapy aims to suppression of autoimmune response using glucocorticoids and immunosuppressive drugs. In large part of patients the response to standard treatment is not sufficient and less common synthetic compounds, biological drugs or intravenous immunoglobulins need to be used. Most patients with inclusion body myositis has limited or no effect of any treatment.Key words: autoantibodies - autoimmunity - inflammation - myopathy - myositis - systemic disease.

AB - Vasculitides with positivity of autoantibodies to neutrophil leukocytes cytoplasm (ANCA, AAV) belong to primary vasculitides involving small and less commonly medium size blood vessels. Three different clinical types of AAV can be distinguished: granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis. Since these autoantibodies seem to be weak activity biomarkers of AAV new molecules and factors start to come up, e.g. neutrophil extracellular traps NET, several T-lymphocyte subpopulations and different immunoglobulins classes of ANCA. In modern biological therapy rituximab is widely used, for refractory cases intravenous immunoglobulins and antithymocyte globulin are recommended. The data from clinical trials with alemtuzumab are controversial, but avacopan selective inhibitor of C5a receptor and inhibitor of B-lymphocyte activation factor belimumab are promise for future.Key words: biologicals - biomarkers - eosinophilic granulomatosis with polyangiitis - granulomatosis with polyangiitis - microscopic polyangiitis.

AB - Diffuse alveolar hemorrhage (DAH) is a life-threatening acute manifestation of systemic diseases, the most commonly of systemic vasculitis. Clinically DAH manifests by a rapidly progressive respiratory and renal failure. The decisive for diagnose is immediate bronchoscopic examination with the bronchoalveolar lavage examination. CT mostly show bilateral pulmonary infiltrates, in blood picture rapidly come to anemia. In the majority of patients it can be found positive ANCA antibodies. DAH should be suspected in the case of acute respiratory failure also in patients without history of systemic disease. On the set of 33 patients with acute DAH episode, we demonstrate the importance of rapid diagnosis and aggressive therapy. In a third of our patients was DAH the first manifestation of systemic disease. Immunomodulatory treatment must be initiated immediately after diagnose. Hospital mortality in our group was 27 %, although 42 % of the patients were required ventilation support and one-third of patients had acute renal failure. After handling of acute episode of DAH is the prognosis quoad vitam promising.Key words: bronchoalveolar fluid - diffuse alveolar haemorrhage - granulomatosis with polyangiitis - intensive care in rheumatology - vasculitis.

It mainly affects the Caucasian race and roughly 2-3 times as many women. From the viewpoint of etiology, polymyalgia rheumatica is a complex disease. Involved in its origin is genetic predisposition, factors of age and outer environment. 16-21 % of patients with polymyalgia rheumatica may at the same time have symptoms of giant cell arteritis. Diagnosis is made primarily on the basis of clinical symptoms and it is supported by the presence of laboratory signs of inflammation. There is no specific diagnostic test available for diagnosing polymyalgia rheumatica. In recent time modern imaging devices, e.g. ultrasonography or positron emission tomography, can be used in diagnosing the disease. In the past a number of diagnostic and classification criteria were established which may be used in diagnosing of polymyalgia rheumatica in general practice. The differential diagnostics of the disease is extensive. Before the treatment commencement it is necessary to rule out the presence of another disease with manifestations simulating polymyalgia rheumatica. The treatment strategy should draw on the current EULAR/ACR Recommendations for the treatment of polymyalgia rheumatica issued in 2015.Key words: polymyalgia rheumatica - positron emission tomography - prognosis - treatment - ultrasonography. PMID- 29595284 TI - [Treat to target in gouty arthritis]. AB - Gout is a crystal-induced, metabolically determined inflammatory rheumatic disease with increasing prevalence. In clinical practice, gout causes frequent diagnostic as well as therapeutic problems. The golden diagnostic standard is crystalographic analysis and evidence of monosodium urate crystals in the polarization microscope; if this is not available, the diagnosis can be established through a combination of clinical, laboratory and imaging techniques. The acute gouty attack must be treated by quick administration of anti inflammatory medicines, with available alternatives being nonsteroidal antirheumatic drugs (NSA), colchicine and glucocorticoids. When the attack subsides, hypouricemic therapy is initiated which should combine the regimen and diet measures and pharmacological treatment. Recommendations for the treatment of gout were published by the EULAR and the Czech Society for Rheumatology. Recently a new strategy appeared known as Treat to target - T2T. This principle has been successfully used in the treatment of rheumatiod arthritis and spondyloarthritis. The publication is structured as four overarching principles and nine Recommendations. The recommendations emphasize long-term maintenance of serum levels of uric acid below 360 MUmol/l as the basic gout-related target in all patients, and below 300 MUmol/l for patients with tophies. It is recommended to administer prophylactic small doses of colchicine for at least 3-6 months on the commencement of hypouricemic therapy. The Recommendations further emphasize the need for regular monitoring of comorbidities and the kidney function. A separate recommendation is concerned with necessary education of patients and their motivation toward compliance with regimen measures and increased physical activity.Key words: colchicine - gouty arthritis - treat to target principle.

AB - Knee osteoarthritis is one of the most frequent diagnoses of load-carrying joints encountered in orthopaedic surgeons offices. Depending on the clinical stage, the therapy starts with conservative treatment. Corrective osteotomy is indicated in younger patients without an extensive and serious impairment. Implantation of TKR (total knee replacement) is usually indicated in more advanced stages. One of the pillars of conservative therapy is analgesics and non-steroidal antirheumatic drugs. A specific group consists of perorally administered drugs for suppression of symptoms or even deceleration of knee osteoarthrosis. These products are popular mainly thanks to their good tolerance and minimal side effects. The clinical effect ranges between minimal and medium depending on the degree of osteoarthrosis, type of drug and study. Similar to rheumatologists, orthopaedic surgeons also find it difficult to identify candidates suitable for a particular type of therapy, except indication for TKR. By all means, nutraceuticals are still considered part of clinical practice.Key words: chondroitin sulphate - glucosamine sulphate - knee osteoarthrosis - methylsulfonylmethane - nutraceuticals - pharmaceutical intervention.

AB - How people react emotionally to an event can tell us much about the event itself. However, emotions vary in their situative informativeness, that is, in how much information about the situation they provide. We predicted that when emotions are shown that are low in situative informativeness participants rely more on context information, then when the emotions shown are high in situative informativeness. This hypothesis was tested in 2 studies in which participants were asked to evaluate the quality of a player's performance based on the emotional reactions of spectators to an unknown ball game. Spectators reacted either with awe (high in situative informativeness), or with happiness or neutrality (low in situative informativeness). Participant also received context information. The findings supported the predictions and illustrate how emotions and context interact to inform us about events. (PsycINFO Database Record PMID- 29595287 TI - Perceptions of belongingness and social support attenuate PTSD symptom severity among firefighters: A multistudy investigation. AB - Firefighters experience high rates of posttraumatic stress disorder (PTSD). It is imperative to identify malleable factors that protect against the development of PTSD symptoms among this population. We examined whether perceptions of belongingness broadly (Study 1) and social support from supervisors, coworkers, and family/friends specifically (Study 2) are associated with lower PTSD symptom severity among firefighters. Study 1 included 840 U.S. firefighters (91.1% male); participants completed the Interpersonal Needs Questionnaire and PTSD Checklist Civilian Version. Study 2 included 200 U.S. women firefighters exposed to a Criterion A traumatic event; participants completed the Generic Job Stress Questionnaire, Life Events Checklist for Diagnostic and Statistical Manual of Mental Disorders-5, and PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5. Linear regression analyses were conducted, adjusting for the number of years participants served as firefighters. Greater belongingness broadly (Study 1; b = -0.740, p < .001) as well as social support specifically (Study 2) from supervisors (b = -4.615, p < .001), coworkers (b = -4.465, p = .001), and family/friends (b = -3.206, p = .021) were associated with less severe PTSD symptoms. When all sources of social support were entered into a single model, only support from supervisors was significantly associated with lower overall PTSD symptom severity (b = -4.222, p = .004). Belongingness and social support may protect against the development of PTSD among firefighters. Supervisor social support may be particularly salubrious, suggesting that top down mental wellness promotion within the fire service may be indicated to protect firefighters against PTSD. (PsycINFO Database Record PMID- 29595289 TI - Daily micro-breaks and job performance: General work engagement as a cross-level moderator. AB - Despite the growing research on work recovery and its well-being outcomes, surprisingly little attention has been paid to at-work recovery and its job performance outcomes. The current study extends the work recovery literature by examining day-level relationships between prototypical microbreaks and job performance as mediated by state positive affect. Furthermore, general work engagement is tested as a cross-level moderator weakening the indirect effects of microbreaks on job performance via positive affect. Using multisource experience sampling method, the authors collected two daily surveys from 71 call center employees and obtained objective records of daily sales performance for two consecutive weeks (n = 632). Multilevel path analysis results showed that relaxation, socialization, and cognitive microbreaks were related to increased positive affect at work which, in turn, predicted greater sales performance. However, breaks for nutrition-intake (having snacks and drinks) did not show significant effects. Importantly, microbreaks had significant indirect effects on job performance via positive affect only for workers who had lower general work engagement, whereas the indirect effects did not exist for workers who had higher general work engagement. Furthermore, Bayesian multilevel analyses confirmed the results. Theoretical and practical implications, limitations, and future research directions are discussed. (PsycINFO Database Record PMID- 29595290 TI - Parental executive function and verbal ability matter for scaffolding. AB - Despite the importance of parental scaffolding for later child cognitive outcomes and academic achievement, sources of individual variation in scaffolding are not fully understood. Scaffolding places extensive demands on cognitive capacity, including planning, flexibly shifting, and inhibition. Executive function (EF) is therefore a parental cognitive ability especially important for effective scaffolding. In this study, parents and preschool-aged children completed a challenging puzzle to assess scaffolding. EF and verbal ability were measured for parents and children. Parental verbal ability was used as an index of global higher-order cognitive function. Higher levels of parental EF related to more effective scaffolding, above and beyond parental verbal ability and independent of child cognitive level. These results highlight the significance of considering parental cognitive capacities in future studies to better understand the sources of individual differences in scaffolding. (PsycINFO Database Record PMID- 29595291 TI - Method biases in single-source personality assessments. AB - The magnitude of components of variance in trait scales-true score, method variance, and error-can be estimated from information on the mono-method correlations among personality traits within a domain and on cross-observer agreement on domains and facets. Estimates of these components in NEO Inventory facet scales were compared with prior estimates that were based on a consideration of internal consistency and retest reliability (McCrae, 2015). Together, results suggested that (a) about 40% of the variance in self-reports and single informant ratings is due to method variance; (b) as with substantive traits, method biases exist on several different levels, some broad, some narrow; and (c) consequently, a large number of distinct biases affect personality scale scores. Method biases beyond acquiescence and evaluation were also found in a clinical instrument, the Personality Inventory for DSM-5. Because many biases appear to be idiosyncratic, it is unlikely that validity scales could be created to assess or control all of them. These findings underscore the value of utilizing multiple informants in research and individual assessment. To the extent that they can be distinguished from valid variance, method biases are themselves of clinical interest as potentially important elements of the self concept. (PsycINFO Database Record PMID- 29595292 TI - Imaginary alternatives: The effects of mental simulation on powerless negotiators. AB - This research demonstrates that people can act more powerfully without having power. Researchers and practitioners advise people to obtain alternatives in social exchange relationships to enhance their power. However, alternatives are not always readily available, often forcing people to interact without having much power. Building on research suggesting that subjective power and objective outcomes are disconnected and that mental simulation can improve aspirations, we show that the mental imagery of a strong alternative can provide some of the benefits that real alternatives provide. We tested this hypothesis in one context of social exchange-negotiations-and demonstrate that imagining strong alternatives (vs. not) causes powerless individuals to negotiate more ambitiously. Negotiators reached more profitable agreements when they had a stronger tendency to simulate alternatives (Study 1) or when they were instructed to simulate an alternative (Studies 3-6). Mediation analyses suggest that mental simulation enhanced performance because it boosted negotiators' aspirations and subsequent first offers (Studies 2-6), but only when the simulated alternative was attractive (Study 5). We used various negotiation contexts, which also allowed us to identify important boundary conditions of mental simulations in interdependent settings: mental simulation no longer helped when negotiators did not make the first offer, when their opponents simultaneously engaged in mental simulation (Study 6), and even backfired in settings where negotiators' positions were difficult to reconcile (Study 7). An internal meta-analysis of the file drawer produces conservative effect size estimates and demonstrates the robustness of the effect. We contribute to social power, negotiations, and mental simulation research. (PsycINFO Database Record PMID- 29595293 TI - A tutorial on regularized partial correlation networks. AB - Recent years have seen an emergence of network modeling applied to moods, attitudes, and problems in the realm of psychology. In this framework, psychological variables are understood to directly affect each other rather than being caused by an unobserved latent entity. In this tutorial, we introduce the reader to estimating the most popular network model for psychological data: the partial correlation network. We describe how regularization techniques can be used to efficiently estimate a parsimonious and interpretable network structure in psychological data. We show how to perform these analyses in R and demonstrate the method in an empirical example on posttraumatic stress disorder data. In addition, we discuss the effect of the hyperparameter that needs to be manually set by the researcher, how to handle non-normal data, how to determine the required sample size for a network analysis, and provide a checklist with potential solutions for problems that can arise when estimating regularized partial correlation networks.

AB - Continuous time dynamic models are similar to popular discrete time models such as autoregressive cross-lagged models, but through use of stochastic differential equations can accurately account for differences in time intervals between measurements, and more parsimoniously specify complex dynamics. As such they offer powerful and flexible approaches to understand ongoing psychological processes and interventions, and allow for measurements to be taken a variable number of times, and at irregular intervals. However, limited developments have taken place regarding the use of continuous time models in a fully hierarchical context, in which all model parameters are allowed to vary over individuals. This has meant that questions regarding individual differences in parameters have had to rely on single-subject time series approaches, which require far more measurement occasions per individual. We present a hierarchical Bayesian approach to estimating continuous time dynamic models, allowing for individual variation in all model parameters. We also describe an extension to the ctsem package for R, which interfaces to the Stan software and allows simple specification and fitting of such models. To demonstrate the approach, we use a subsample from the German socioeconomic panel and relate overall life satisfaction and satisfaction with health.

AB - This article describes benchmark validation, an approach to validating a statistical model. According to benchmark validation, a valid model generates estimates and research conclusions consistent with a known substantive effect. Three types of benchmark validation-(a) benchmark value, (b) benchmark estimate, and (c) benchmark effect-are described and illustrated with examples. Benchmark validation methods are especially useful for statistical models with assumptions that are untestable or very difficult to test. Benchmark effect validation methods were applied to evaluate statistical mediation analysis in eight studies using the established effect that increasing mental imagery improves recall of words. Statistical mediation analysis led to conclusions about mediation that were consistent with established theory that increased imagery leads to increased word recall. Benchmark validation based on established substantive theory is discussed as a general way to investigate characteristics of statistical models and a complement to mathematical proof and statistical simulation.

PMID- 29595296 TI - Determining synchrony between behavioral time series: An application of surrogate data generation for establishing falsifiable null-hypotheses. AB - Synchrony between interacting systems is an important area of nonlinear dynamics in physical systems. Recently psychological researchers from multiple areas of psychology have become interested in nonverbal synchrony (i.e., coordinated motion between two individuals engaged in dyadic information exchange such as communication or dance) as a predictor and outcome of psychological processes. An important step in studying nonverbal synchrony is systematically and validly differentiating synchronous systems from nonsynchronous systems. However, many current methods of testing and quantifying nonverbal synchrony will show some level of observed synchrony even when research participants have not interacted with one another. In this article we demonstrate the use of surrogate data generation methodology as a means of testing new null-hypotheses for synchrony between bivariate time series such as those derived from modern motion tracking methods. Hypotheses generated by surrogate data generation methods are more nuanced and meaningful than hypotheses from standard null-hypothesis testing. We review four surrogate data generation methods for testing for significant nonverbal synchrony within a windowed cross-correlation (WCC) framework. We also interpret the null-hypotheses generated by these surrogate data generation methods with respect to nonverbal synchrony as a specific use of surrogate data generation, which can then be generalized for hypothesis testing of other psychological time series.

AB - The co-occurrence of posttraumatic stress disorder (PTSD) and substance use is related to poorer outcome and increased dropout from trauma-focused treatment. Investigating PTSD and substance use can inform the intervention approaches. Exploring cannabis use in particular is especially important because rates of cannabis use have been increasing with recent legalization trends. A better understanding of how substance use is associated with treatment processes and outcome for individuals with PTSD is needed to enhance care. In this study, both lifetime diagnoses of alcohol and drug use disorders and current alcohol and drug use severity were examined in 200 men and women with chronic PTSD who received either prolonged exposure (PE) or sertraline. No lifetime or current alcohol use variables predicted dropout, adherence, or poorer outcome. However, lifetime diagnosis of both an alcohol and drug disorder (OR = 3.42) and recent cannabis use (OR = 3.38) strongly predicted higher dropout. Recent cannabis use and drug use severity predicted poorer adherence to PE (beta = -.22 to -.29) but not to sertraline. Drug use severity (beta = -.22) also predicted worse treatment outcome, as did lifetime diagnosis of an alcohol and drug disorder (beta = -.48). Overall, patients with drug use improved with treatment but had less treatment retention, adherence, and symptom reduction. Strategies to increase engagement and retention may be indicated for these patients. Individuals who are using cannabis or other drugs may be at higher risk for not completing PTSD treatment, potentially prolonging the cycle of PTSD and substance use.

AB - The future of groups of people is a topic of broad interest in society and academia. Nonetheless, relatively little is known about the manner in which people think about the collective future of groups, and whether personal and collective future thinking represent distinct domains of future-oriented cognition. In the present studies (N = 691), we used an adapted future fluency task to demonstrate a novel domain-by-valence interaction between personal and collective future thinking, such that U.S.-based participants were positively biased about their personal future while at the same time being negatively biased about the future of their country. We further present evidence that this valence based dissociation extends into the distant future, emerges in a non-U.S. (Canadian) sample, depends on the individual's relation to the group, and has consequences for how people think about the world around them. Taken together, our findings represent the first behavioral evidence of a dissociation between personal and collective future thinking, and suggest that the study of collective future thinking represents a fruitful endeavor for psychological science. (PsycINFO Database Record PMID- 29595298 TI - Decision-making and socioeconomic disparities in colonoscopy screening in African Americans. AB - BACKGROUND: Socioeconomic status (SES) disparities in colorectal cancer screening are persistent. Lower education and income are both associated with lower screening rates. Both cognitive (e.g., perceived barriers) and affective (e.g., disgust, fear) decision-making constructs are known determinants of colorectal cancer screening behavior. This study tests the hypotheses that SES may be related to decision-making constructs and that this SES-decision-making construct relation may contribute to explaining the SES-screening behavior disparity. METHOD: Surveys assessing perceived benefits and barriers to screening, self efficacy, positive and negative affective associations with colonoscopy, fear of colonoscopy, colorectal cancer knowledge, past screening behavior, and demographics including education and income were completed by 2,015 African American participants ages 50 and older. Both univariable and multivariable relations of SES to decision-making constructs were examined, as were univariable and multivariable models of the indirect effect of SES on screening via decision making constructs. RESULTS: Socioeconomic status was related to both screening compliance and the decision-making constructs. Bootstrap modeling of the indirect effect showed that the total effect of the SES-screening behavior relation included an indirect effect via social cognitive decision-making constructs. CONCLUSION: These findings suggest that cognitive and affective decision-making constructs account for at least some of the SES disparities in colorectal cancer screening behavior. As such, more research is needed to explore the intra individual-level influences of disparities in colorectal cancer screening. In addition, work is needed to develop effective intervention approaches to address the relation of SES to decision-making constructs.

Verhage, Carlo Schuengel, Sheri Madigan, R. M. Pasco Fearon, Mirjam Oosterman, Rosalinda Cassibba, Marian J. Bakermans-Kranenburg and Marinus H. van IJzendoorn (Psychological Bulletin, 2016[Apr], Vol 142[4], 337-366). In the article, there are errors in Table 7. The percentages of the attachment classifications do not add up to 100%. The corrected version of Table 7 is provided in the erratum. (The following abstract of the original article appeared in record 2015-55801-001.) Twenty years ago, meta-analytic results (k = 19) confirmed the association between caregiver attachment representations and child-caregiver attachment (Van IJzendoorn, 1995). A test of caregiver sensitivity as the mechanism behind this intergenerational transmission showed an intriguing "transmission gap." Since then, the intergenerational transmission of attachment and the transmission gap have been studied extensively, and now extend to diverse populations from all over the globe. Two decades later, the current review revisited the effect sizes of intergenerational transmission, the heterogeneity of the transmission effects, and the size of the transmission gap. Analyses were carried out with a total of 95 samples (total N = 4,819). All analyses confirmed intergenerational transmission of attachment, with larger effect sizes for secure-autonomous transmission (r = .31) than for unresolved transmission (r = .21), albeit with significantly smaller effect sizes than 2 decades earlier (r = .47 and r = .31, respectively). Effect sizes were moderated by risk status of the sample, biological relatedness of child-caregiver dyads, and age of the children. Multivariate moderator analyses showed that unpublished and more recent studies had smaller effect sizes than published and older studies. Path analyses showed that the transmission could not be fully explained by caregiver sensitivity, with more recent studies narrowing but not bridging the "transmission gap." Implications for attachment theory as well as future directions for research are discussed. (PsycINFO Database Record PMID- 29595301 TI - Publishing papers that matter. AB - Daniel G.

AB - Research suggests that people make better weather-related decisions when they are given numeric probabilities for critical outcomes (Joslyn & Leclerc, 2012, 2013). However, it is unclear whether all users can take advantage of probabilistic forecasts to the same extent. The research reported here assessed key cognitive and demographic factors to determine their relationship to the use of probabilistic forecasts to improve decision quality. In two studies, participants decided between spending resources to prevent icy conditions on roadways or risk a larger penalty when freezing temperatures occurred. Several forecast formats were tested, including a control condition with the night-time low temperature alone and experimental conditions that also included the probability of freezing and advice based on expected value. All but those with extremely low numeracy scores made better decisions with probabilistic forecasts. Importantly, no groups made worse decisions when probabilities were included. Moreover, numeracy was the best predictor of decision quality, regardless of forecast format, suggesting that the advantage may extend beyond understanding the forecast to general decision strategy issues. This research adds to a growing body of evidence that numerical uncertainty estimates may be an effective way to communicate weather danger to general public end users.

AB - Studies have shown that prequestions-asking students questions before they learn something-benefit memory retention. Prequestions would seem to be a useful technique for enhancing students' learning in their courses, but classroom investigations of prequestions have been sparse. In the current study, students from an introductory psychology course were randomly assigned to receive prequestions over each upcoming lesson (prequestion group) or to not receive prequestions (control group). At the end of class, students in the prequestion group remembered the material better than students in the control group, but this benefit was specific to the information that was asked about in the prequestions. When memory for other, nonprequestioned portions of the lesson were tested at the end of class, the prequestion group performed similarly to the control group. On a follow-up quiz 1 week later, both groups showed a memory advantage for material that was tested at the end of class 1 week prior, compared with information from the same lesson that was never tested. However, this benefit was comparable between the prequestion group and the control group, suggesting that students benefit from retrieval practice, but prequestions add little, if any, enhancement to this effect.

AB - To the extent that people feel more continuity between their present and future selves, they are more likely to make decisions with the future self in mind. The current studies examined future self-continuity in the context of health. In Study 1, people reported the extent to which they felt similar and connected to their future self; people with more present-future continuity reported having better subjective health across a variety of measures. In Study 2, people were randomly assigned to write a letter to themselves either three months or 20 years into the future; people for whom continuity with the distant future self was enhanced exercised more in the days following the writing task. These findings suggest that future self-continuity promotes adaptive long-term health behavior, suggesting the promise of interventions enhancing future self-continuity. (PsycINFO Database Record PMID- 29595305 TI - Self-persuasion in media messages: Reducing alcohol consumption among students with open-ended questions. AB - Self-persuasion (self-generation of arguments) is often a more effective influence technique than direct persuasion (providing arguments). However, the application of this technique in health media communications has received limited attention. In two experiments, it was examined whether self-persuasion can be successfully applied to antialcohol media communications by framing the message as an open-ended question. In Experiment 1 (N = 131) cognitive reactions to antialcohol posters framed either as open-ended questions or statements were examined. In Experiment 2 (N = 122) the effectiveness of this framing to reduce actual alcohol consumption was tested. Experiment 1 demonstrated that exposure to an antialcohol poster framed as an open-ended question resulted in more self generated arguments for drinking less alcohol and more favorable message evaluations than framing the same message as a statement. Experiment 2 showed that the self-persuasion poster did not affect the choice to consume alcohol but did reduce alcohol consumption for individuals who chose to drink any alcohol, compared with a direct persuasion poster or no intervention. Together, the results demonstrated the potential of self-persuasion in persuasive media messages for interventions aimed at alcohol consumption reduction specifically and for health communication in general. (PsycINFO Database Record PMID- 29595306 TI - Sensory substitution: Using a vibrotactile device to orient and walk to targets. AB - This study investigates how active exploration helps users of sensory substitution devices (SSDs) to detect action-relevant information. A vibrotactile SSD was developed that generates stimulation that is contingent on the users' movements. Target direction was specified by the location of the vibratory stimulation, and target distance by the size and intensity of the pattern of stimulation. A series of experiments was performed with blindfolded participants. In Experiments 1a to 1c, participants used the SSD to align their central body axis with prespecified targets. These experiments differed in the number of actuators that were used and whether online perception-action coupling was present. In Experiment 2, participants approached targets with forward locomotion along a straight line. Experiment 3 combined the previous experiments and studied the concomitant walking and steering toward targets. Oscillatory movements, which facilitated information pickup, were observed in all experiments. The exploratory oscillations were shown to depend on the online perception-action coupling and were related to cases of hyperacuity, for which absolute errors were found to be smaller than the areas of sensitivity of the actuators. It is concluded that, to improve the utility of SSDs, future research with SSDs should pay more attention to the role of active information detection. (PsycINFO Database Record PMID- 29595307 TI - Night awakening in infancy: Developmental stability and longitudinal associations with psychomotor development. AB - Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor development (Bayley Scales of Infant and Toddler Development [Bayley-III]; Bayley, 2009) was investigated in infants with (>=3 night awakenings, n = 81) and without fragmented sleep (<=1 night awakening, n = 70) within the CHILD-SLEEP birth cohort at 8 and 24 months of age. Differences in parent-reported (Brief Infant Sleep Questionnaire [BISQ]) sleep parameters were studied at 8, 18, and 24 months of age. Group differences in night awakening were stable across all assessment points. Infants with fragmented sleep slept less in total than infants without fragmented sleep and they did not compensate their nocturnal sleep during daytime. Additionally, infants with fragmented sleep spent more time awake at night than infants without fragmented sleep. However, psychomotor development did not differ between infants with and without fragmented sleep at 8 or 24 months of age. Our findings indicate that early onset fragmented sleep did not have a negative effect on psychomotor development within the first 2 years despite the differences in sleep length among infants with and without fragmented sleep. In the future, more specific domains of cognitive development and various factors affecting sleep fragmentation should be taken into account when studying the developmental effects of night awakening in infancy. (PsycINFO Database Record PMID- 29595308 TI - The association between religiousness and children's altruism: The role of the recipient's neediness. AB - We examined the role of the recipient's neediness as a moderator in the relation between children's household religiosity and prosocial behavior. Examining the behavior of children (2nd and 5th graders) from religious and nonreligious households in the dictator game, we found that the extent of sharing did not differ significantly between the 2 groups when the recipient was not described as needy. However, when the recipient was presented as a poor (needy) child, the religious group exhibited significantly more sharing behavior. Although the religious children's tendency to share more with needy recipients compared with the not-needy ones appeared already in the 2nd grade, it increased with age as children grew and internalized the norms of their immediate society. Among the major religions, the recipient's neediness is an important variable in the decision to give, which shapes religious children's prosocial behavior from an early age. Thus, future research should take this moderator into account when studying the relation between religiousness and prosociality in general and in the development of prosociality in children in particular. (PsycINFO Database Record PMID- 29595309 TI - Feeling loved and integrated or lonely and rejected in everyday life: The role of age and social motivation. AB - Social approach and social avoidance goals (i.e., approach of positive and avoidance of negative outcomes in social situations) are important predictors of the feeling of being socially integrated or isolated. However, little is known about the development of these goals across adulthood. In a large diary study with N = 744 young (18-39 years), middle-aged (40-59 years), and older adults (60 83 years), we tested the hypothesis that the adaptiveness of social goals changes across adulthood: Social approach goals were hypothesized to be adaptive during young adulthood when adult social relationships are to be established. In contrast, social avoidance goals were hypothesized to become more adaptive with age as people are increasingly motivated to avoid interpersonal tension. Our findings support these hypotheses: Social approach goals were positively and social avoidance goals negatively associated with younger but not with middle aged and older adults' daily social well-being. These results were robust across different situations (positive, negative) and different types of relationships (close, peripheral). The study highlights the changing role of social approach and avoidance goals for daily social well-being across adulthood. (PsycINFO Database Record PMID- 29595310 TI - From map reading to geometric intuitions. AB - The origins and development of our geometric intuitions have been debated for millennia. The present study links children's developing intuitions about the properties of planar triangles to their developing abilities to read purely geometric maps. Six-year-old children are limited when navigating by maps that depict only the sides of a triangle in an environment composed of only the triangle's corners and vice versa. Six-year-old children also incorrectly judge how the angle size of the third corner of a triangle varies with changes to the other two corners. These limitations in map reading and in judgments about triangles are attenuated, respectively, by 10 and 12 years of age. Moreover, as children get older, their map reading predicts their geometric judgments on the triangle task. Map reading thus undergoes developmental changes that parallel an emerging capacity to reason explicitly about the distance and angle relations essential to euclidean geometry. (PsycINFO Database Record PMID- 29595311 TI - The effects of shared storybook reading on word learning: A meta-analysis. AB - Although an abundant literature documents preliterate children's word learning success from shared storybook reading, a full synthesis of the factors which moderate these word learning effects has been largely neglected. This meta analysis included 38 studies with 2,455 children, reflecting 110 effect sizes, investigating how reading styles, story repetitions, tokens and related factors moderate children's word comprehension, while adjusting for the number of target words. Dialogic reading styles, tokens, and the number of words tested all moderated word learning effects. Children's age, who read the story, and time between story and test were not moderators. We identify story repetition and word types as topics which merit further research. These results provide information to guide researchers and educators alike to the factors with the greatest impact on improving word learning from shared storybook reading. (PsycINFO Database Record PMID- 29595313 TI - You don't need to talk to throw a ball! Children's inclusion of language-outgroup members in behavioral and hypothetical scenarios. AB - To investigate children's inclusion of language-outgroup members, English speaking children (8-9 years and 10-11 years of age, N = 57) made inclusion decisions while playing a simulated ball-tossing game, Cyberball, and while evaluating hypothetical scenarios involving language-outgroup members who wanted to play with their group. In the Cyberball game, the group norm was to exclude non-English-speaking peers, and participant tosses to a language-outgroup member (i.e., Spanish, Chinese, or Arabic speaking) were coded as a measure of behavioral inclusion. In the hypothetical scenarios, participants made prescriptive and descriptive judgments about their expectations regarding the inclusion of a language-outgroup member. They also evaluated their own and their group's inclusion likelihood. Results revealed that participants' evaluations of how acceptable exclusion was predicted their behavioral inclusion in the Cyberball game. Further, participants were more likely to think that the language outgroup member should be included and less likely to think that the outgroup member would be included. They also differentiated between their own and their group's likelihood of including a language-outgroup member and reasoned about this decision by focusing on group functioning and language. In addition, there were age-related differences, with participants demonstrating greater inclusivity with age. The findings suggest the complexity of children's social cognition and the importance of providing them with a rich array of opportunities to play with language-outgroup members. (PsycINFO Database Record PMID- 29595312 TI - CPS-referred mothers' psychophysiological responses to own versus other child predict sensitivity to child distress. AB - Maltreating mothers often struggle to respond sensitively to their children's distress. Examining psychophysiological processing of own child cues may offer insight into neurobiological mechanisms that promote sensitive parenting among high-risk mothers. The current study used event-related potential (ERP) methodology to examine associations between mothers' neural responses to their own child versus other children and observed sensitivity to distress. Participants included 73 mothers: 42 with histories of child protective services (CPS) involvement and 31 low-risk comparison mothers. Maternal sensitivity to child distress was coded from observations of children's blood sample collection. Late positive potential (LPP) ERP responses, which reflect sustained attention to emotionally salient stimuli, were measured when mothers viewed photos of their own child and other children. An own-other LPP difference score (own-other LPP) was computed by regressing the mean amplitude of mothers' LPP to their own child on the mean amplitude of mothers' LPP to other children. CPS-referred mothers and low-risk mothers did not differ in their LPP responses to own child, other children, or the own-other LPP. However, there was a significant interaction between group (CPS-referred vs. low-risk) and own-other LPP in predicting maternal sensitivity. Among the CPS-referred mothers, own-other LPP was significantly correlated with maternal sensitivity, with greater LPP amplitude to own versus other child associated with higher maternal sensitivity. In contrast, among the low-risk group, own-other LPP was not significantly correlated with maternal sensitivity. Findings add to our understanding of the neurobiology of sensitive parenting among high-risk mothers.

PMID- 29595314 TI - Trajectories of cannabis-related associative memory among vulnerable adolescents: Psychometric and longitudinal evaluations. AB - Indirect tests of memory associations relevant to cannabis have been shown to be useful in explaining and predicting adolescent cannabis use habits. This study sought to increase the understanding of adolescent cannabis-related associative memory and cannabis use behavior over time. A longitudinal sample of alternative high school students (N = 775) was assessed yearly for 3 years. The study first conducted extensive longitudinal measurement analyses of the cannabis-related word association test (WAT) applying contemporary psychometric models. Second, the study examined the longitudinal trajectories of cannabis-related associative memory and cannabis use and their contemporaneous and longitudinal relationships. Results showed that the cannabis-related WAT provided strong evidence of sound psychometric properties. Longitudinal change in cannabis-related associative memory was best described by modeling either a linearly decreasing trajectory or two separate trajectories: During middle adolescence, levels of cannabis-related associative memory were highest and stable but then gradually decreased toward late adolescence. Moreover, cannabis-related associative memory was contemporaneously predictive of cannabis use within ages 15 to 19 while controlling for the underlying growth process of cannabis use and time-invariant covariates (TICs) of gender and lifetime concurrent use of alcohol and cigarettes. Partial support of longitudinal prediction of cannabis use was also obtained from age 17 to 18 and age 19 to 20 while adjusting for growth in cannabis use and the TICs. These results demonstrated that predictive effects of cannabis-related memory associations on cannabis use were detected within some of the 1-year age spans and were consistent within ages across adolescent years. (PsycINFO Database Record PMID- 29595316 TI - Double-Equivocal HER2 Invasive Breast Carcinomas: Institutional Experience and Review of Literature. AB - CONTEXT.-: HER2 status is a prognostic factor and therapeutic target in invasive breast carcinomas. Reflex testing using an alternate method is recommended on equivocal cases via immunohistochemistry or fluorescence in situ hybridization (FISH). Therapeutic dilemmas arise when both tests are equivocal. The standard chromosome 17 centromere reference probe (CEP17) is in close proximity to the HER2 locus and may be coamplified, leading to equivocal results. Alternate chromosome 17 reference probes may aid in establishing the true HER2 status. OBJECTIVE.-: To describe our institutional experience using D17S122 probe for reflex FISH testing on double-equivocal invasive breast carcinomas and review the literature on alternate reference probes. DATA SOURCES.-: Twenty-two patients with double-equivocal invasive breast carcinomas, defined as HER2 immunohistochemistry score 2+ and FISH equivocal per the 2013 guidelines, were reviewed. Reflex FISH was performed with alternate probe D17S122 and the HER2 status classified for 11 cases by using a revised HER2: D17S122 ratio. Seven of 11 cases (63.6%) were ultimately classified as HER2 positive, while 4 cases (36.4%) remained equivocal. The 7 positive cases showed a HER2: D17S122 greater than 2.0. CONCLUSIONS.-: Alternate probe D17S122 reclassified more than half of our cases as HER2 positive. Alternate probes may establish true HER2 status and direct proper management, as evidenced by our experience and the literature. Additional investigation is needed to determine which alternate probe(s) is(are) best for reflex testing. Finally, the American Society of Clinical Oncology/College of American Pathologists guidelines may need to be updated to reflect more specific recommendations for the utilization of appropriate probes in double-equivocal HER2 cases.

PMID- 29595317 TI - Quantitative Assessment of Immunohistochemistry Laboratory Performance by Measuring Analytic Response Curves and Limits of Detection. AB - CONTEXT: - Numerous studies highlight interlaboratory performance variability in diagnostic immunohistochemistry (IHC) testing. Despite substantial improvements over the years, the inability to quantitatively and objectively assess immunostain sensitivity complicates interlaboratory standardization. OBJECTIVE: - To quantitatively and objectively assess the sensitivity of the immunohistochemical stains for human epidermal growth factor receptor type 2 (HER2), estrogen receptor (ER), and progesterone receptor (PR) across IHC laboratories in a proficiency testing format. We measure sensitivity with parameters that are new to the field of diagnostic IHC: analytic response curves and limits of detection. DESIGN: - Thirty-nine diagnostic IHC laboratories stained a set of 3 slides, one each for HER2, ER, and PR. Each slide incorporated a positive tissue section and IHControls at 5 different concentrations. The IHControls comprise cell-sized clear microbeads coated with defined concentrations of analyte (HER2, ER, and/or PR). The laboratories identified the limits of detection and then mailed the slides for quantitative assessment. RESULTS: - Each commercial immunostain demonstrated a characteristic analytic response curve, reflecting strong reproducibility among IHC laboratories using the same automation and reagents prepared per current Good Manufacturing Practices. However, when comparing different commercial vendors (using different reagents), the data reveal up to 100-fold differences in analytic sensitivity. For proficiency testing purposes, quantitative assessment using analytic response curves was superior to subjective interpretation of limits of detection. CONCLUSIONS: - Assessment of IHC laboratory performance by quantitative measurement of analytic response curves is a powerful, objective tool for identifying outlier IHC laboratories. It uniquely evaluates immunostain performance across a range of defined analyte concentrations. PMID- 29595319 TI - Electroconvulsive therapy in a patient with metallic implant.

AB - OBJECTIVE: To investigate the rates of thyroid nodules and cancer in pediatric cases of Hashimoto's thyroiditis (HT) in Korea. METHODS: We retrospectively reviewed 89 pediatric and adolescent patients (age, 3-18.0 years) with HT who underwent thyroid ultrasonography (US) at our institution from February 2006 to July 2016. The diagnosis of HT was based on the presence of thyroid autoantibodies. The presence of any thyroid nodules with US and cytopathologic features was analyzed. The malignancy rate was also determined. RESULTS: Thyroid nodules were in 20 of the 89 patients (22.4%). Eight of these 20 patients (40%) had colloid cysts, two (10%) had nodular hyperplasia, one (5%) had follicular adenoma, and two (10%) had lymphocytic thyroiditis. Seven of the 89 patients (7.9%) were confirmed to have a malignancy, all of which were papillary thyroid carcinoma (PTC); of those, five patients had diffuse sclerosing variant PTC, and two had conventional PTC on pathology. CONCLUSION: The prevalence of thyroid nodules in children and adolescents with HT was 22.4%. The malignancy rate of children with HT was 7.9%. The malignancy rate among thyroid nodules was 35%, which is higher than the 26% rate generally reported for children with nodules. Therefore, using thyroid US to survey known or suspected thyroid nodules might be helpful in children and adolescents with HT and may provide further useful diagnostic information. Advances in knowledge: Thyroid US could help to assess HT patients who have known or suspected thyroid nodules. PMID- 29595321 TI - Influence of graded inclusion of white lupin (Lupinus albus) meal on performance, nutrient digestibility and ileal viscosity of laying hens. AB - 1. The aim of this study was to investigate the effect of white lupin (Lupinus albus) meal (WLM) addition on the intestinal viscosity, bird performance and nutrient utilisation of laying hens. 2. The experiment was conducted with 360 laying hens aged 21 weeks fed one of 6 treatments, including a corn-soybean meal control diet (CON) and 5 experimental diets containing 60, 120, 180, 240 and 300 g/kg WLM. 3. A linear increase in feed intake (p < 0.001) was observed with higher levels of WLM from 0 to 300 g/kg. Laying rate decreased quadratically (p < 0.05) and egg weight (at 6th, 12th and 18th weeks of the trial) decreased linearly with WLM inclusion from 0 to 300 g/kg. Birds fed 60 g/kg or more of WLM laid lighter eggs (p < 0.05) than CON hens. When 240 g/kg or more WLM was included into the diet, laying rate was affected negatively (p < 0.05). 4. As WLM increased from 0 to 300 g/kg, apparent metabolisable energy and pre-caecal digestibility of dry matter and crude protein decreased quadratically (p < 0.05). When 300 g/kg of WLM was used, there was a tendency (p < 0.1) to decrease pre caecal starch digestibility. WLM dose exerted a quadratic effect (p < 0.05) on total sialic acid excretion. As WLM increased, the viscosity of ileal digesta linearly increased (p < 0.05). 5. In the 6th and 12th weeks of the experiment (p < 0.05), eggshell thickness decreased linearly when 240 g/kg of WLM was added. At the 6th, 12th and 18th weeks, a linear decrease in eggshell content was observed (p < 0.05) after WLM addition. 6. In conclusion, the graded inclusion of WLM into laying hens' diets resulted in depressed performance, AMEN and eggshell quality. PMID- 29595322 TI - Cone beam computed tomography virtual navigation-guided transthoracic biopsy of small (<= 1 cm) pulmonary nodules: impact of nodule visibility during real-time fluoroscopy. AB - OBJECTIVE: To evaluate the impact of nodule visibility during real-time fluoroscopy and other biopsy-related variables on the diagnostic accuracy and complication rates of cone beam CT (CBCT) virtual navigation (VN)-guided percutaneous transthoracic needle biopsies (PTNBs) of small (<=1 cm) pulmonary nodules. METHODS: Patients (99 males and 114 females; age, 62.1 +/- 11.1 years) who underwent CBCT VN-guided biopsies for lung nodules <= 1 cm were retrospectively reviewed. The visibility of target nodules was assessed on the captured fluoroscopy images. Diagnostic accuracies were calculated and logistic regression analyses were performed to determine independent influencing factors for the correct diagnosis and complications (pneumothoraxes and hemoptysis) in CBCT VN-guided PTNBs, respectively. RESULTS: Among 213 nodules, 63 (29.6%) were invisible on real-time fluoroscopy during VN. The diagnostic accuracy of CBCT VN guided PTNBs for the invisible nodules was 76.7%, while for the visible nodules was 89.1% (p = 0.042). In the logistic regression analysis, the visibility of a target nodule (odds ratio = 2.49, p = 0.047) was the only independent influencing factor for a correct diagnosis. As regards complication rates, nodule visibility was not a significant factor for the occurrence of a pneumothorax or hemoptysis. CONCLUSION: Although nodule visibility on real-time fluoroscopy was an affecting factor for the correct diagnosis, CBCT VN-guided PTNB was feasible for the invisible nodules with diagnostic accuracy of 76.7%. Advance in knowledge: CBCT VN-guided PTNB can be tried safely for the subcentimeter-sized pulmonary nodules regardless of their fluoroscopic visibility. PMID- 29595323 TI - CT and MR imaging characteristics of histological subtypes of head and neck ossifying fibroma. AB - OBJECTIVES: The current study aimed to assess CT and MRI characteristics of histological subtypes of head and neck ossifying fibroma (OF). METHODS: 12 patients with histopathologically-proven head and neck OF were included in this study. Lesions were pathologically classified into three histological subtypes: eight cement-OFs (COFs), three juvenile psammomatoid OFs (JPOFs), and one juvenile trabecular OF (JTOF). All patients underwent CT examination, while seven also underwent MRI. Imaging characteristics were retrospectively assessed. RESULTS: On CT images, the lesion margins were well-defined in nine patients (75%) (seven COFs and two JPOFs), partially ill-defined in two (17%) (one COF and one JTOF), and ill-defined in one (8%) (one JPOF). The continuity of the eroded overlying bone cortex was maintained in nine patients (75%) (seven COFs and two JPOFs) but disrupted in three (25%) (one COF, one JPOF, one JTOF). With respect to lesion density, homogeneous ground-glass opacity was observed in five patients (42%) (five COFs), target-like appearance in three (25%) (two COFs, one JPOF), and mixture of hyper- and hypodense areas were observed in four (33%) (one COF, two JPOFs, one JTOF). MR signal intensity was homogeneous in two patients (29%) (two COFs) and heterogeneous in five (71%) (two COFs, two JPOFs, one JTOF). CONCLUSIONS: COFs tended to exhibit well-defined margins and preserved continuity of the overlying bone cortex. COFs were usually homogeneous, whereas JPOFs and JTOF were always heterogeneous. Target-like appearance was one of the characteristics of OFs, but it was observed in both COF and JPOF. PMID- 29595324 TI - Rhizome of Anemarrhena asphodeloides as mediators of the eco-friendly synthesis of silver and gold spherical, face-centred cubic nanocrystals and its anti migratory and cytotoxic potential in normal and cancer cell lines. AB - The water extract of Anemarrhena asphodeloides, the traditional oriental medicinal plant, mediated the eco-friendly synthesis of silver nanoparticles (Aa AgNPs) and gold nanoparticles (Aa-AuNPs). First, its therapeutic rhizome was powdered prior to water extraction and then silver, gold nanoparticles were synthesized. Aa-AgNPs and Aa-AuNPs were found to be spherical, face-centred cubic nanocrystals with a Z-average hydrodynamic diameter of 190 and 258 nm, respectively. In addition, proteins and aromatic biomolecules were the plausible players associated with the production and stabilization of Aa-AgNPs; instead, phenolic compounds were responsible for the synthesis and stability of Aa-AuNPs. In vitro cytotoxic analysis revealed that up to 50 MUg.mL-1 concentration Aa AuNPs did not exhibit any toxicity on 3T3-L1, HT29 and MCF7 cell lines, while being specifically cytotoxic to A549 cell line. On the contrary, Aa-AgNPs displayed a significantly higher toxicity in comparison to Aa-AuNPs in all cell lines specially MCF7 cell line. Since cancer cells were more sensitive to Aa Au/AgNPs treatments, further evaluation was done in order to determine their anticancer potential. Reactive oxygen species (ROS) generation was not affected by Aa-AuNPs, on the other hand, Aa-AgNPs treatment exhibited a higher potential to induce oxidative stress in A549 cells than HT29 and MCF7 cells. In addition, Aa-Ag/AuNPs reduced cell migration in A549 cells at 10 and 50 MUg.mL-1, respectively. So far, this is the only report uncovering the ability of A. asphodeloides to synthesize silver and gold nanoparticles with anticancer potential and also indirectly enabling its large-scale utilization with value addition. PMID- 29595325 TI - Cartilage can be thicker in advanced osteoarthritic knees: a tridimensional quantitative analysis of cartilage thickness at posterior aspect of femoral condyles. AB - OBJECTIVE: To test, through tridimensional analysis, whether (1) cartilage thickness at the posterior aspect of femoral condyles differs in knees with medial femorotibial osteoarthritis (OA) compared to non-OA knees; (2) the location of the thickest cartilage at the posterior aspect of femoral condyles differs between OA and non-OA knees. METHODS: CT arthrograms of knees without radiographic OA (n = 30) and with severe medial femorotibial OA (n = 30) were selected retrospectively from patients over 50 years of age. The groups did not differ in gender, age and femoral size. CT arthrograms were segmented to measure the mean cartilage thickness, the maximal cartilage thickness and its location in a region of interest at the posterior aspect of condyles. RESULTS: For the medial condyle, mean and maximum cartilage thicknesses were statistically significantly higher in OA knees compared to non-OA knees [1.66 vs 1.46 mm (p = 0.03) and 2.56 vs 2.14 mm (p = 0.003), respectively]. The thickest cartilage was located in the half most medial aspect of the posterior medial condyle for both groups, without significant difference between groups. For the lateral condyle, no statistically significant difference between non-OA and OA knees was found (p >= 0.17). CONCLUSION: Cartilage at the posterior aspect of the medial condyle, but not the lateral condyle, is statistically significantly thicker in advanced medial femorotibial OA knees compared to non-OA knees. The thickest cartilage was located in the half most medial aspect of the posterior medial condyle. These results will serve as the basis for future research to determine the histobiological processes involved in this thicker cartilage. Advances in knowledge: This study, through a quantitative tridimensional approach, shows that cartilage at the posterior aspect of the medial condyles is thicker in severe femorotibial osteoarthritic knees compared to non-OA knees. In the posterior aspect of the medial condyle, the thickest cartilage is located in the vicinity of the center of the half most medial aspect of the posterior medial condyle. These results will serve as the basis for future research to determine the histobiological processes involved in this thicker cartilage. PMID- 29595326 TI - A real-world analysis of glycemic control among patients with type 2 diabetes treated with canagliflozin versus dapagliflozin. AB - OBJECTIVE: This US retrospective cohort study compared the real-world effectiveness of canagliflozin 300 mg versus dapagliflozin 10 mg on HbA1c reduction in patients with type 2 diabetes mellitus (T2DM). METHODS: Patients initiated on canagliflozin 300 mg or dapagliflozin 10 mg were identified from de identified claims data in the Optum Clinformatics database (1 January 2014-30 September 2016). Propensity score matching was used to create balanced cohorts. The primary outcome was the proportion of patients with HbA1c <8.0% (HEDIS target); secondary outcomes included the proportion of patients with HbA1c <7.0% (ADA target) and >9.0% (HEDIS poor control), absolute change in HbA1c, and treatment patterns. RESULTS: At 6 months post-index (intent-to-treat population), a significantly higher proportion of patients in the canagliflozin 300 mg versus dapagliflozin 10 mg cohort achieved HbA1c <8.0% (70.8% vs. 59.1%; OR [95% CI]: 1.60 [1.26, 2.04]; p = .0001) and HbA1c <7.0% (36.7% vs. 25.1%; OR [95% CI]: 1.75 [1.34, 2.27]; p < .0001). A similar proportion of patients had HbA1c >9.0%. Mean HbA1c reduction was -1.17% with canagliflozin 300 mg and -0.91% with dapagliflozin 10 mg (difference of -0.26%; p = .0049). HbA1c results from a sensitivity analysis in the on-treatment population were consistent with the primary analysis. Patients in the canagliflozin 300 mg versus dapagliflozin 10 mg cohort were less likely to discontinue treatment (OR [95% CI]: 0.75 [0.57, 0.99]; p = .0400) or switch medication (OR [95% CI]: 0.72 [0.54, 0.96]; p = .0229). CONCLUSIONS: In this real-world study, patients with T2DM initiated on canagliflozin 300 mg had better HbA1c goal attainment and larger HbA1c reduction than patients initiated on dapagliflozin 10 mg. PMID- 29595327 TI - The antioxidant system in the soleus muscle of growing rats is stimulated by the administration of a low-protein/high-carbohydrate diet. AB - The aim of this study was to evaluate the generation of reactive oxygen species (ROS) by xanthine oxidase (XO), the enzymatic antioxidant system and oxidative damage in soleus and extensor digitorum longus (EDL) muscles of growing rats fed a low-protein, high-carbohydrate (LPHC; 6% protein, 74% carbohydrate) diet for 15 days. The LPHC diet increased the total antioxidant capacity by 45% and the activities of glutathione peroxidase (GPx), glutathione reductase and catalase in the soleus muscles. There was an increase in the carbonylated proteins with no increase thiobarbituric acid reactive substances (TBARS), although the XO activity had increased 20%. In EDL muscles, the LPHC diet increased XO activity by 66% and the TBARS levels by 80%, and only GPx had its activity increased. These results suggest that the enzymatic antioxidant system of the soleus muscle has a better response to the increase of ROS production stimulated by LPHC diet. PMID- 29595328 TI - Bt354 as a new STAT3 signaling pathway inhibitor against triple negative breast cancer. AB - Inhibition of the signal transducer and activator of transcription 3 (STAT3) signalling pathway has been considered as a novel therapeutic strategy to treat human cancers with constitutively active STAT3. In this study, we screened 1563 compounds and identified Bt354 as a new small-molecule inhibitor of the STAT3 signalling pathway. The effect of Bt354 on STAT3 activity was initially screened and Bt354 significantly inhibited STAT3 activity in a dual luciferase assay. Bt354 inhibited the proliferation of cancer cells in a dose- and time-dependent manner. The phosphorylation of STAT3 at Y705 was suppressed without affecting the phosphorylation of STAT3 at S727 in breast cancer cells. Furthermore, Bt354 inhibited the nuclear translocation of STAT3 and consequently induced cell growth inhibition, apoptosis and cell cycle G2/M arrest in triple negative breast cancer cells. In vivo, Bt354 also inhibited tumour growth in MDA-MB-435 and MDA-MB-231 xenograft mice without affecting body weight. Computational modelling showed that Bt354 could bind to the SH2 domain of STAT3. These findings suggest that Bt354 may be a potent anticancer agent for STAT3-activated triple negative breast cancer cells. PMID- 29595329 TI - Sacubitril and valsartan protect from experimental myocardial infarction by ameliorating oxidative damage in Wistar rats. AB - BACKGROUND: Sacubitril (SAC), a neprilysin inhibitor prevent degradation of neprilysin and activate cGMP signaling pathways leading to rise in blood volume concurrent to blood pressure by means of vasoactive peptides, adrenomedullin, and bradykinin. OBJECTIVE: The aim of this study was to evaluate the anti-ischemic effects of SAC through inhibiting neprilysin in isoproterenol (ISO) induced myocardial infarction (MI) in Wistar albino rats. ISO (85 mg/kg) was injected subcutaneously at the end of 14 days pre-treatment with SAC and valsartan (VAL). RESULT: Biochemical investigation revealed that SAC along with VAL significantly prevented the antioxidant enzymes (SOD, Catalase, GR, GPx, GST, and GSH) degradation and malondialdehyde (MDA) induced by ISO intoxication in Wistar rats. Along with this, cardiac biomarkers (LDH, CK-MB, ALT, AST, and ALP) were also significantly ameliorated by SACand VAL in ISO-treated rats. Concurrently, decreased infarction area (IA)and marked reduction in myofibril damage by SACand VAL further supported its protective benefits in MI. CONCLUSION: Taken together, the results suggest that inhibition of enzyme neprilysin alleviated the ISO induces myocardial damage mediated by its strong antioxidant potential. PMID- 29595330 TI - Neuroprotective Effects of Psalmotoxin-1, an Acid-Sensing Ion Channel (ASIC) Inhibitor, in Ischemia Reperfusion in Mouse Eyes. AB - PURPOSE: The purpose of the current study is to assess changes in the expression of Acid-Sensing Ion Channel (ASIC)1a and ASIC2 in retinal ganglion cells (RGCs) after retinal ischemia and reperfusion (I/R) injury and to test if inhibition of ASIC1a provides RGC neuroprotection. METHODS: Transient ischemia was induced in one eye of C57BL/6 mice by raising intraocular pressure to 120 mmHg for 60 min followed by retinal reperfusion by restoring normal pressure. RGC function was measured by Pattern electroretinography (PERG). In addition, retinal ASIC1a and ASIC2 were observed by immunohistochemistry and western blot. Changes in calpain, fodrin, heat shock protein 70 (HSP70), Brn3a, super oxide dismutase-1 (SOD1), catalase, and glutathione perioxidase-4 (GPX4) protein levels were assessed by western blot. RGC numbers were measured by immunohistochemistry on whole retinal flat mounts using anti-RNA binding protein with multiple splicing (RBPMS) antibodies. Intravitreal injection of psalmotoxin-1, a selective ASIC1a blocker, was used to assess the neuroprotective effect of ASIC1a inhibition. RESULTS: Levels of ASIC1a and ASIC2 after I/R increased in RGCs. Upregulation of ASIC1a but not ASIC2 was attenuated by intravitreal injection of psalmotoxin-1. I/R induced activation of calpain and degradation of fodrin, HSP70, and reduction in Brn3a. In contrast, while psalmotoxin-1 attenuated calpain activation and increased Brn3a levels, it failed to block HSP70 degradation. Unlike SOD1 protein which was reduced, catalase protein levels increased after I/R. Psalmotoxin-1, although not affecting SOD1 and GPX4, increased catalase levels significantly. Psalmotoxin-1 also increased RBPMS-labeled RGCs following I/R as judged by immunohistochemistry of retinal flat mounts. Finally, psalmotoxin-1 enhanced the amplitude of PERG following I/R, suggesting partial rescue of RGC function. CONCLUSION: Psalmotoxin-1 appears to exert a neuroprotective effect under ischemic insults and targeting inhibition of ASICs may represent a new therapeutic approach in ischemic retinal diseases. PMID- 29595331 TI - Vegetarianism, depression, and the five factor model of personality. AB - This study investigated whether vegetarians and omnivores differ in their personality characteristics. We measured the five factor model of personality and depressive symptoms in vegetarians, who avoided meat and fish (n = 276); semi vegetarians, who ate some meat and/or fish (n = 1191); and omnivores (n = 4955). Although vegetarians and semi-vegetarians were more open to new experiences, they were more neurotic and depressed than omnivores. Neither conscientiousness nor agreeableness varied as a function of dietary habits. These findings contribute to our understanding about differences between vegetarians' and omnivores' personalities, which might help us better understand individual differences in food preferences. PMID- 29595332 TI - Three-dimensional CBCT images registration method for TMJ based on reconstructed condyle and skull base. AB - OBJECTIVES: A method was introduced for three-dimensional (3D) cone-beamCT (CBCT) images registration of temporomandibular joint (TMJ). This study aimed to provide quantitative and qualitative analysis of TMJ bone changes in two-dimensional (2D) and 3D and to provide the technique for computer-aided diagnosis of temporomandibular joint disorders in the future. METHODS: 10 TMJ samples of six patients were obtained from Peking University Hospital of Stomatology. Four of the six patients imaged bilateral TMJs and the other two patients only imaged unilateral TMJ. Each sample consisted of two images from the same TMJ taken at different times. First, condyle and skull base were segmented semi-automatically for 3D model reconstruction. Then the segmented condyle and skull base were registered separately. Registration process can be divided into two processes of rough registration and fine registration. Rough registration step was achieved by selecting corresponding points manually and initialized fine registration. Condyle and skull base were fine registered by minimizing mean square error of condyle (MSEcondyle) and skull base (MSEskull) respectively. Qualitative assessment of osseous component changes utilized 2D color-fused model and 3D surface-fused model and quantitative analyses the convergence of this method used the mean square error of the model (MSEmodel). Independent repeated experiments were carried out to test the stability of our 3D registration method. RESULTS: Sufficiently alignment was achieved. Osseous abnormality and morphology changes were displayed using fusion model. MSEmodel of condylar registration and skull base registration declined 51.80% and 64.58% compared with that before registration. Quantitative analysis verified the stability of the method. CONCLUSIONS: The proposed method completed 3D TMJ registration for different physiological structure. The result of this method was accurate, reproducible and not relied on the experience of operators. PMID- 29595333 TI - Computer vision analysis captures atypical attention in toddlers with autism. AB - To demonstrate the capability of computer vision analysis to detect atypical orienting and attention behaviors in toddlers with autism spectrum disorder. One hundered and four toddlers of 16-31 months old (mean = 22) participated in this study. Twenty-two of the toddlers had autism spectrum disorder and 82 had typical development or developmental delay. Toddlers watched video stimuli on a tablet while the built-in camera recorded their head movement. Computer vision analysis measured participants' attention and orienting in response to name calls. Reliability of the computer vision analysis algorithm was tested against a human rater. Differences in behavior were analyzed between the autism spectrum disorder group and the comparison group. Reliability between computer vision analysis and human coding for orienting to name was excellent (intra-class coefficient 0.84, 95% confidence interval 0.67-0.91). Only 8% of toddlers with autism spectrum disorder oriented to name calling on >1 trial, compared to 63% of toddlers in the comparison group (p = 0.002). Mean latency to orient was significantly longer for toddlers with autism spectrum disorder (2.02 vs 1.06 s, p = 0.04). Sensitivity for autism spectrum disorder of atypical orienting was 96% and specificity was 38%. Older toddlers with autism spectrum disorder showed less attention to the videos overall (p = 0.03). Automated coding offers a reliable, quantitative method for detecting atypical social orienting and reduced sustained attention in toddlers with autism spectrum disorder. PMID- 29595334 TI - Concordance between physiological arousal and emotion expression during fear in young children with autism spectrum disorders. AB - This study aimed to measure emotional expression and physiological arousal in response to fear in 21 children with autism spectrum disorders (43-75 months) and 45 typically developing children (41-81 months). Expressions of facial and bodily fear and heart rate arousal were simultaneously measured in response to a remote controlled robot (Laboratory Temperament Assessment Battery). Heart rate analyses revealed a main effect of task from baseline to fear ( p < 0.001, [Formula: see text]), no interaction effect and no effect for group. In addition, children with autism spectrum disorder showed intact facial and bodily expressions of fearful affect compared to typically developing children. With regard to the relationship between expression and arousal, the results provided evidence for concordance between expression and arousal in typically developing children ( r = 0.45, n = 45, p < 0.01). For children with autism spectrum disorder, no significant correlation was found ( r = 0.20, n = 21, p = 0.38). A moderation analysis revealed no significant interaction between expression and arousal for children with and without autism spectrum disorder ( F(1, 62) = 1.23, p = 0.27, [Formula: see text]), which might be the result of limited power. The current results give reason to further study concordance between expression and arousal in early autism spectrum disorder. Discordance might significantly impact social functioning and is an important topic in light of both early identification and treatment. PMID- 29595335 TI - Functional changes during visuo-spatial working memory in autism spectrum disorder: 2-year longitudinal functional magnetic resonance imaging study. AB - This study examined functional changes longitudinally over 2 years in neural correlates associated with working memory in youth with and without autism spectrum disorder, and the impact of increasing cognitive load. We used functional magnetic resonance imaging and a visuo-spatial 1-back task with four levels of difficulty. A total of 14 children with autism spectrum disorder and 15 typically developing children (ages 7-13) were included at baseline and followed up approximately 2 years later. Despite similar task performance between groups, differences were evident in the developmental trajectories of neural responses. Typically developing children showed greater load-dependent activation which intensified over time in the frontal, parietal and occipital lobes and the right fusiform gyrus, compared to those with autism spectrum disorder. Children with autism spectrum disorder showed minimal age-related changes in load-dependent activation, but greater longitudinal load-dependent deactivation in default mode network compared to typically developing children. Results suggest inadequate modulation of neural activity with increasing cognitive demands in children with autism spectrum disorder, which does not mature into adolescence, unlike their typically developing peers. Diminished ability for children with autism spectrum disorder to modulate neural activity during this period of maturation suggests that they may be more vulnerable to the increasing complexity of social and academic demands as they progress through adolescence than their peers. PMID- 29595336 TI - Scoping the evidence for EarlyBird and EarlyBird Plus, two United Kingdom developed parent education training programmes for autism spectrum disorder. AB - EarlyBird and EarlyBird Plus are parent education and training programmes designed by the UK National Autistic Society in 1997 and 2003, having been delivered to more than 27,000 families in 14 countries. These group-based programmes aim to (1) support parents immediately after diagnosis of autism spectrum disorder, (2) empower parents, encouraging a positive perception of their child's autism spectrum disorder and (3) help parents establish good practice. In the absence of any previous comprehensive review, we performed a scoping review of all peer-reviewed publications on EarlyBird/EarlyBird Plus. A search was conducted between February and June 2016 using EbscoHost, Sabinet, SAGE Journals, Directory of Open Access Journals, BioMed Central, Scopus, ScienceDirect and grey literature. Two reviewers independently screened titles and abstracts for inclusion. In total, 18 articles were identified: 16 from the United Kingdom and 2 from New Zealand. We reviewed the context, study populations, design, outcome measures, whether focus was on parental perception, parental change or child changes and programme feasibility. Strong parental support for the acceptability but lower level evidence of efficacy of EarlyBird/EarlyBird Plus was found. Future research should consider randomised controlled trials. There is no research on EarlyBird/EarlyBird Plus in low resource settings; therefore, we recommend broader feasibility evaluation of EarlyBird/EarlyBird Plus including accessibility, cultural appropriateness and scalability. PMID- 29595338 TI - Multifunctional fluorescent titania nanoparticles: green preparation and applications as antibacterial and cancer theranostic agents. AB - Theranostic nanoparticles have attracted considerable attention in recently revolutionized medicine. Since the last decade, there has been a growing attempt to design various theranostic nanoparticles but difficulties still exist in the fabrication of their biocompatible one. Herein, fluorescent titania nanoparticles (FTN) were fabricated using a one-step green method. This FTN had ultra-high doxorubicin hydrochloride (DOX) loading capacity (encapsulation efficiency 95.50% and loading content 38.20%) that release the loaded drug in response to acidic pH. In vitro cytotoxicity experiments on human osteosarcoma (SaOs-2) and breast cancer (MCF-7) cell lines revealed superior anticancer efficacy (lowered the IC50 concentration by 3- and 5.5-fold for SaOs-2 and MCF-7 cells, respectively) and also better imaging for intracellular tracking of DOX/FTN relative to free DOX. Furthermore, the prepared nanoparticles showed efficient antibacterial activity against both gram-negative (Escherichia coli ATCC 25922) and gram-positive (Staphylococcus aureus ATCC 25923) bacteria. In this study, we have developed novel theranostic titania nanoparticles with inherent fluorescence property for cancer imaging and therapy. PMID- 29595337 TI - Mitochondria-homing peptide functionalized nanoparticles performing dual extracellular/intracellular roles to inhibit aminoglycosides induced ototoxicity. AB - One of the major challenges in the treatment of hearing loss is the low efficacy of therapeutic candidates. To achieve the optimum drug efficacy, we designed a novel peptide (D-Arg-Dmt-Arg-Phe-NH2)-mediated mitochondrial targeted delivery nanosystem for a promising candidate, geranylgeranylacetone (GGA). The zebrafish lateral line system, a robust model for mammalian hair cells, was used to identify the efficacy against gentamicin, a well-known ototoxic agent. The nanosystem facilitated lysosomal escape and mitochondrial accumulation, and thus conferred superior protective efficacy against a wide range of gentamicin compared with unmodified NPs and free drugs. Meanwhile, peptides-modified NPs internalized hair cells via both of dynamin-dependent and independent routes, following a classic endocytic or autophagy pathway. Although extracellular action via MET channels, the primary protective mechanism underlying peptides-modified NPs was revealed due to their intracellular interaction. Thus, our nanoplatform provided a general strategy to enhance the clinical efficacy of a broad range of drugs in the treatment of hearing loss. PMID- 29595339 TI - Antifeedant activity of long-chain alcohols, and fungal and plant metabolites against pea aphid (Acyrthosiphon pisum) as potential biocontrol strategy. AB - Aphids are noxious insect pests of major crops including cereals and legumes. Particularly, pea aphid (Acyrthosiphon pisum) causes significant yield and quality loses in pea. Crop protection is largely based on noxious chemical pesticides which have prompted a renewed interest in the discovery of natural products as alternatives to synthetic insecticides. In this study different classes of natural compounds were tested in dual choice bioassays to evaluate their feeding deterrence and mortality effect on pea aphid. High feeding deterrence was produced by some of the compounds, particularly1-hexadecanol, gliotoxin, cyclopaldic acid and seiridin. On the contrary, aphid mortality was low although significant for 1-heptadecanol, cytochalasin A, 1-nonadecanol and gliotoxin. Phytotoxicity assessment showed low or imperceptible plant damaged for cytochalasin A, seiridin and 1-nonadecanol. The results obtained showed the potential of seiridin to be used as an alternative to synthetic insecticides. PMID- 29595341 TI - Beneficial Effects of ragi (Finger Millet) on Hematological Parameters, Body Mass Index, and Scholastic Performance among Anemic Adolescent High-School Girls (AHSG). AB - Adolescence is a period characterized by rapid physical, emotional, and mental growth and changes potentially resulting in health challenges. Anemia, which is a fairly common complication in this age group, is reported to negatively affect the cognitive ability of adolescents. Traditionally, ragi (Finger millet: Eleusine coracana), a cereal available in India, has been recommended as nutritional supplement to combat anemia because of its high protein and mineral content as well as anti-microbial property. This study sought to establish the effect of ragi in improving hematological parameters, body mass index, and scholastic performance among adolescent school girls. Sixty adolescent girls were randomly selected and divided into intervention (n = 30) and control groups (n = 30). The effect of dietary supplementation of ragi porridge on hematological parameters was evaluated on the intervention group at 45 and 90 days. Both groups were monitored for changes in body mass index and scholastic performance. A statistically significant increase in hemoglobin levels was observed in the intervention group after 90 days (from a mean of 11.3 g% to 12.54 g%; t (29) = 7.514, p < .0001), with no significant changes in the control group. No statistically significant differences between the two groups were observed for mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular volume, red cell distribution width, body mass index, and scholastic performance. The data show that daily dietary supplementation with ragi porridge has a positive effect on hemoglobin levels in adolescent high schools girls. A well planned nutrition education with dietary supplementation is thus recommended for better outcomes. PMID- 29595340 TI - Correlation of ST changes in leads V4-V6 to area of ischemia by CMR in inferior STEMI. AB - OBJECTIVE: We aim to determine the correlation between ST-segment changes in leads V4-V6 and the extent of myocardial injury by cardiac magnetic resonance (CMR) in patients with inferior ST elevation (STE) myocardial infarction (iSTEMI). DESIGN: Admission electrocardiogram and CMR data from the MITOCARE trial were used. Differences in mean myocardium at risk, infarct size, ejection fraction and myocardial segment involvement by CMR were compared in patients with first iSTEMI with STE, ST depression (STD) or no ST changes (NST) in V4-V6. Myocardial segment involvement was further evaluated by comparing proportion of patients in each group with >=25% and >=50% segment involvement. RESULTS: Fifty four patients were included. Patients with STE (n = 22) and STD (n = 16) in V4-V6 had significantly lower ejection fraction compared to NST (n = 16) (48% vs 48% vs 54%, p = .02). STE showed more apical, apical lateral and mid-inferolateral involvement but less basal inferior involvement than NST. STD exhibited greater basal inferoseptal involvement compared to STE. There were more patients with STE that had >=25% and >=50% apical lateral involvement compared with STD and NST groups. Patients with STD were more likely to have >=25% and >=50% basal inferoseptal involvement compared with STE and NST groups. CONCLUSION: Our study suggests that in iSTEMI, ST changes in the precordial leads V4-V6 correlates with greater myocardial injury and distribution of myocardium at risk. PMID- 29595342 TI - Lifetime alcohol intake and pattern of alcohol consumption in patients with alcohol-induced pancreatitis in comparison with patients with alcohol use disorder. AB - OBJECTIVE: To examine lifetime drinking patterns in men and women with alcohol induced pancreatitis (AIP) in comparison with patients with alcoholic use disorder (AUD) without pancreatic disease. METHODS: Alcohol consumption patterns were assessed using a validated questionnaire, the Lifetime Drinking History (LDH), during an outpatient visit. Patients diagnosed with AIP were matched for gender and age (+/- 5 years) with patients with AUD in addiction treatment. RESULTS: A total of 45 patients with AIP (35 males, 10 females) and 45 AUD patients were included. Alcohol consumption patterns were not significantly different between males and females with AIP and those with history of acute AIP and chronic pancreatitis (CP). Alcohol consumption patterns of AIP and AUD patients were similar in terms of onset age and duration of alcohol consumption, lifetime alcohol intake and drinks per drinking day. A higher proportion of binge drinking was found among patients with AUD than those with AIP (median 1.00 vs. 0.94, p = .01). Males with AUD had lower onset age (15 vs. 16 years, p = .03), higher total amount of spirits (35520 vs. 10450 drinks, p = .04) and higher proportion of binge drinking (1.00 vs. 0.97, p = .01) than males with AIP, whereas females with AIP and AUD had similar drinking patterns. CONCLUSIONS: Alcohol drinking patterns and lifetime drinking history was similar in patients with AIP and patients with AUD. Males with AIP had lower total amount of spirits and lower proportion of binge drinking than those with AUD, suggesting the idiosyncratic etiology of AIP. PMID- 29595343 TI - On the persistence and detectability of ancient Beothuk mitochondrial DNA genomes in living First Nations peoples. AB - Claims have long been made as to the survival to the present day of descendants of the Newfoundland Beothuk, a group generally accepted to have become extinct with the death of the last known member, Shanawdithit, in 1829. Interest has recently been revived by the availability of commercial genetic testing, which some claim can assign living individuals to specific Native American groups. We compare complete mitogenome sequences (16569 bp) from aDNA of eight distinct Beothuk lineages, including Shanawdithit's uncle Nonosabasut and his wife Demasduit, with three Newfoundland Mi'kmaq lineages and 21 other living Native Americans drawn from GenBank. A Newfoundland Mi'kmaq lineage in Haplogroup A is more similar to three Native Americans (1-3 SNPs) than to the most closely related Beothuk (24 SNPs). Nonosabasut in Haplogroup X is identical to a non Beothuk Native American. Demasduit in Haplogroup C differs from three other Native Americans by 1-4 substitutions. Within a 2168 bp region of the HVS sequences available from living Mi'kmaq of the Miawpukek First Nation in Newfoundland, lineages in Haplogroups C, X, and A differ by 1, 4, and 8 substitutions, from the most similar Beothuk, and are more similar to other Native Americans. MtDNA genome sequences in living persons identical or similar to those of Beothuk do not necessarily indicate Beothuk ancestry. Mi'kmaq lineages cannot at this time be associated with any Beothuk lineages more closely than those of other Native Americans. PMID- 29595344 TI - Seroepidemiology and phylogenetic analysis of human herpesvirus type 8 in injection drug users and men who have sex with men in northern Taiwan. AB - Objectives Human herpesvirus 8 (HHV-8) is transmissible and causes Kaposi's sarcoma and other malignancies. This study analyzed the seroepidemiology and phylogeny of HHV-8 among 515 injection drug users (IDUs) and 229 men who have sex with men (MSM) in Taiwan. Methods Blood and peripheral mononuclear cells were analyzed for HHV-8 seroprevalence using enzyme-linked immunosorbent and immunofluorescence assays. Viral loads were measured using a real-time PCR assay. Phylogenetic analysis of the K1 gene was performed using nested PCR and DNA sequencing. Results HHV-8 infection rate was higher in MSM (24.9%) than in IDUs (3.8%). The rate of HHV-8 infection was higher in HIV-1-positive patients (32.8%, MSM; 5.5%, IDUs) than in HIV-1 negative patients. HHV-8 load was not significantly different between HHV-8 seropositive and seronegative patients. HHV 8 genotypes C and A variants were detected at frequencies of 80% and 20%, respectively, among IDUs; and genotypes C, D, E, and A were detected at frequencies of 55.6%, 11.1%, 11.1%, and 5.6%, respectively, among MSM. Variants of K1 amino acid residues 54-84 were detected in most IDUs and MSM. Conclusions HHV-8 prevalence was significantly higher among MSM than among IDUs. Evolution of the K1 gene occurred in HHV-8 variants of IDUs and MSM. PMID- 29595345 TI - Respira project: Humanistic and economic burden of asthma in Brazil. AB - OBJECTIVE: To determine the association of asthma on health-related quality of life (QoL), productivity, and use of healthcare resources among adults in Brazil. METHODS: Data were analyzed from the 2015 Brazil National Health and Wellness Survey, a cross-sectional survey with 12,000 adult respondents. Asthma and control groups were compared with respect to health-related QoL, asthma control, work productivity, and adherence. Generalized linear models were developed to compare asthma-related associations controlling for potential confounding factors. RESULTS: Among respondents, 4.1% (n = 494) reported an asthma diagnosis; those without asthma symptoms were used as the control group (n = 11,487). Regarding asthma control, 51.2% of patients had uncontrolled asthma, 36.4% partially controlled asthma, and 12.3% were fully controlled. Short-acting beta2 agonists were the most commonly used class of drugs (38.5%). Approximately 32.4% of asthma patients were considered fully adherent to their treatment. In multivariable analyses, asthma patients presented lower health-related QoL and had more frequent visits with medical healthcare providers (6.1 versus 4.2) emergency room visits (1.0 versus 0.5), and more hospitalizations (0.4 versus 0.2), than control respondents six months prior to the study (p < 0.05). Rates of absenteeism and presenteeism varied between 11.5% and 7.4% (p < 0.05) and 30.4% and 20.9% (p < 0.001) between asthma patients and controls, respectively. CONCLUSIONS: Asthma had a negative association on health-related QoL, work productivity, and use of healthcare resources. Excessive use of short-acting beta2 agonists and poor treatment adherence reflect poor asthma control and suggest the need to implement new strategies for asthma treatment in Brazil. PMID- 29595346 TI - A proteomic approach reveals the variation in human platelet protein composition after storage at different temperatures. AB - Cryopreservation can slow down the metabolism and decrease the risk of bacterial contamination. But, chilled platelets (PLTs) show a reduced period in circulation due to the rapid clearance by hepatic cells or spleen macrophages after transfusion. The deleterious changes that PLTs undergo are mainly considered the result of PLT protein variation. However, the basis for proteomic variation of stored PLTs remains poorly understood. Besides count, activation markers (CD62P and Annexin V), and aggregation, we used quantitative mass spectrometry to create the first comprehensive and quantitative human PLT proteome of samples stored at different temperatures (22 degrees C, 10 degrees C and -80 degrees C). We found different conditions caused different platelet storage lesion (PSL). PLT count was decreased no matter at what temperature stored. PLTs viability at low temperature dropped by 21.78% and 11.21%, respectively, as compared 10.26% at room temperature, there were no significant differences between the storage methods. Membrane expression of CD62P gradually increased in all groups especially stored at 22 degrees C up to 40% and 10 degrees C up to 30%. However, exposure of PS on the PLT membrane was below 1% in every group. The PLT proteome showed there were 575 and 454 potential proteins identified by general iTRAQ analysis and phosphorylation iTRAQ a nalysis, respectively, among them, 33 common differentially expressed proteins caused by storage time and 44 caused by storage temperature Especially, membrane-bound proteins (such as FERMT3, STX4, MYL9 and TAGLN2) played key roles in PLT storage lesion. The pathways "Endocytosis", "Fc gamma R-mediated phagocytosis" and "Regulation of actin cytoskeleton" were affected predominantly by storage time. And the pathways "SNARE interactions in vesicular transport" and "Vasopressin-regulated water reabsorption" were affected by cold storage in our study. Proteomic results can help us to understand PLT biochemistry and physiology and thus unravel the mechanisms of PSL in time and space for more successful PLT transfusion therapy. PMID- 29595347 TI - Relationship between human immunodeficiency virus (HIV-1) infection and chronic periodontitis. AB - INTRODUCTION: Current studies show that, even in the era of antiretroviral therapies, HIV-1 infection is associated with more severe and frequent refractory chronic periodontitis. Areas covered: This review, based on a systematic analysis of the literature, intends to provide an update on factors that may be involved in the pathogenesis of periodontal disease in HIV-1-infected patients, including local immunosuppression, oral microbial factors, systemic inflammation, salivary markers, and the role of gingival tissue as a possible reservoir of HIV-1. Expert commentary: The therapeutic revolution of ART made HIV-1 infection a chronic controllable disease, reduced HIV-1 mortality rate, restored at least partially the immune response and dramatically increased life expectancy of HIV-1-infected patients. Despite all these positive aspects, chronic periodontitis assumes an important role in the HIV-1 infection status for activating systemic inflammation favoring viral replication and influencing HIV-1 status, and also acting as a possible reservoir of HIV-1. All these issues still need to be clarified and validated, but have important clinical implications that certainly will benefit the diagnosis and management of chronic periodontitis in HIV-1-infected patients, and also contributes to HIV-1 eradication. PMID- 29595349 TI - Rebuttal from Saltin and Calbet. PMID- 29595348 TI - PARP inhibitors for homologous recombination-deficient prostate cancer. AB - INTRODUCTION: Prostate adenocarcinoma represents a leading cause of cancer related mortality. Increased emphasis on understanding the molecular basis of prostate cancer has identified a substantial burden of homologous recombination (HR) pathway mutations, which are enriched in castrate-resistant disease. This discovery has yielded novel therapeutic opportunities. Areas covered: We will discuss the treatment of castrate-resistant prostate cancer (CRPC), with a focus on the use of poly (ADP-ribose) polymerase (PARP) inhibitors in this space. Evidence for use in HR-deficient patients will be outlined with discussion of the mechanism of action for this drug class, pathways of resistance, and approaches for expanding PARP inhibitor use to non-HR-deficient prostate cancer subgroups. Expert opinion: PARP inhibition represents an exciting tool for management of HR inactivated CRPC. With rapid adoption of next-generation sequencing technologies and other molecular techniques, the number of patients in this category is likely to increase. Ongoing and future investigations will be critical for improved understanding of the promise and appropriate treatment sequencing of PARP inhibition and optimal options for HR-proficient and -deficient prostate cancer populations. Questions remain about the clinical significance of monoallelic vs. biallelic HR mutations, the relevance of germline vs. somatic-only mutations, and the importance of mutations in non-canonical HR genes. PMID- 29595350 TI - Factors influencing the level of self-stigmatisation in people with mental illness. AB - AIM: The aim of this study was to assess sociodemographic factors and factors connected with treatment of mental illness and to decide whether they can influence the level of self-stigma. METHOD: Sociodemographic characteristics (age, gender, family status, level of employment, level of education) and characteristics related to illness and treatment (diagnosis, length of treatment, adherence to treatment) were gathered in a group of patients in stable mental condition, without acute symptoms of mental illness. Self-stigma was measured using the Self-stigma of Mental Illness Scale - short form (SSMIS-SF). RESULTS: The sample included 197 patients: 99 patients in group 1 (G1) with psychosis and 98 in group 2 (G2) with anxious and affective disorders. The average age was 44.15 +/- 12.91 years, the length of illness was 11.67 +/- 9.21 years and 48% of patients were men. The total average SSMIS-SF score was 61.54 +/- 23.34. We found no statistically significant difference in the total level of self-stigmatisation between these groups ( t(197) = 0.77; p = .441). The level of self-stigmatisation (total score of SSMIS-SF) in patients in G1 (psychosis) increased with the length of illness r(99) = .253; p = .011. Employment status seems to correlate with the level of self-stigmatisation ( F(3, 184) = 5.27; p = .002). Patients unemployed and on disability pension had higher levels of self-stigmatisation than patients working full-time. Patients who took medication regularly (full medical adherence) had lower scores of SSMIS-SF total scores in comparison with patients with lower compliance ( t(195) = 3.476; p = .001; Cohen's d = .25). CONCLUSION: According to our results, with regard to the factors that were followed, self stigmatisation correlates with the presence of employment (social inclusion), duration of illness in patients with psychosis and treatment adherence. We did not find a statistically significant influence of age, gender, marital status or clinical diagnosis on the level of self-stigma.

AB - INTRODUCTION: Current antiretroviral therapy allows to achieve and sustain maximal suppression of HIV replication in most treated patients. As result, the life expectancy of HIV-infected persons has improved dramatically and is nowadays similar to that of the HIV-negative population. However, oral antiretrovirals have to be taken daily and indefinitely to avoid resumption of HIV replication and selection of drug resistance. Unfortunately, drug adherence is often suboptimal and tends to decline over time. Areas covered: New drugs, formulations and delivery systems are being developed for extended-release of antiretrovirals. At this time, intramuscular cabotegravir and rilpivirine, dapivirine vaginal rings and tenofovir alafenamide subdermal implants are the products in more advanced stages of clinical development. Their pharmacokinetics/dynamics and safety/efficacy are reviewed. Expert commentary: In the absence of eradicative therapy for individuals with HIV infection and protective vaccines for persons at risk, long-term antiretroviral therapy is the best approach for preventing disease progression in patients and halting transmissions, either as result of 'treatment as prevention' for HIV carriers or 'pre-exposure prophylaxis' for uninfected individuals at risk. In all these scenarios, the advent of long-acting antiretrovirals will expand options for overcoming the challenge of suboptimal drug adherence and reduce the burden of HIV infection. PMID- 29595352 TI - The inhibitory effect of functional lesions on eloquent brain areas: from research bench to operating bed. AB - OBJECTIVES: Functioning, but injured cerebral connections are hypothesized to inhibit cortical plasticity. Study of neural networks can validate this hypothesis, and provide further practical clues for clinical and surgical options to restore function in eloquent brain areas. MATERIAL AND METHODS: Cortical lesions in eloquent areas were simulated by means of artificial neural networks. Next, functional restoration of these networks after lesional bypass was studied. RESULTS: The accuracy of network outputs was reduced from 92% to 72% (P-value < 0.001) when logical temporal connections with dysfunctional lesions were established. Restoration of function was almost totally achieved by bypassing the lesion, without any significant changes in network nodal weights. Estimated remaining functional fraction errors were trivial (0.0044%-1.4%). DISCUSSION: Examples of functional decline due to disturbing signals are Todd's paralysis and Landau-Kleffner syndrome. Functional restoration after lesionectomy in eloquent areas of the brain is also practiced. Likewise, injured connections provide routes of influence for disturbing impulses. CONCLUSION: Herein, the proposed evidences provide theoretical clues to formulate new avenues in restorative functional neurosurgery. They may help to identify suitable lesions and suitable techniques for functional restoration including dissection of disturbing connections, bridging and bypassing lesions that can be corroborated by simulation.

AB - Objective A minor alteration in the posterior occlusal height elicits a large transformation in the anterior vertical dimension. Thus, the present study was performed to determine whether a posterior cusp-to-cusp relation that increases the posterior vertical dimension contributes to an anterior open bite. Methods Study casts were examined from orthodontic patients aged 10 to 27 years, 21 with an open bite and 28 with a scissor deep bite. A logistic regression model was used to analyze the contribution of various factors to these two anterior occlusal patterns. The dental arch width and number of worn cusps were compared between the two groups. Results Patients with an open bite had a significantly higher incidence of a posterior buccal-lingual cusp-to-cusp relation, wider mandibular arch in the molar region, and larger numbers of worn maxillary buccal cusps and mandibular lingual cusps than patients with a scissor deep bite. Conclusions A posterior buccal-lingual cusp-to-cusp relation is associated with a larger anterior vertical dimension, such as that in patients with an open bite.

AB - INTRODUCTION: Cardiac ablation is an established treatment modality for the management of patients with cardiac arrhythmias. Current approaches to cardiac ablation employ thermal based energy to achieve lesions (damage) within the heart. There are many shortcomings and limitations of thermal based approaches. Electroporation (DC energy) is a non-thermal alternative approach to ablation that has shown significant promise in animal studies. Areas covered: An extensive review of the literature on the application of electroporation for ablation (both cardiac and collateral cardiac tissue) was undertaken. This review explores irreversible electroporation as a cardiac ablation modality. Specifically, it focuses and explains the biophysics of electroporation, the limitations of current thermal based approaches and examines the current data published on electroporation cardiac ablation. Expert commentary: Electroporation is a fast growing novel ablation modality that has many advantages over current thermal based approaches. Current research in animal models shows its can be safely and efficaciously applied to the heart. Although further research is required, electroporation represents an appealing option for the ablation cardiac arrhythmias.

AB - Among the neurological manifestations of systemic lupus erythematosus (SLE), chorea is rare, presenting in less than 7% of the pediatric SLE patients. It can appear early in the onset of SLE, be the first or even the sole clinical feature of the illness and has strongly been associated with the presence of antiphospholipid antibodies. We report on the case of a 13-year old boy, admitted with acute onset chorea and finally diagnosed with SLE. Subsequently, we present a short review of the literature on the epidemiology, suggested pathogenesis, clinical presentation and treatment of this rare presentation of SLE.

AB - Case series summary This was a retrospective study on the clinical features and response to treatment in seven cats with feline hyperaesthesia syndrome (FHS) and tail mutilation. FHS is a poorly understood disorder characterised by skin rippling over the dorsal lumbar area, episodes of jumping and running, excessive vocalisation, and tail chasing and self-trauma. The majority of the cats were young, with a median age of 1 year at the onset of clinical signs, male (n = 6) and with access to the outdoors (n = 5). Multiple daily episodes of tail chasing and self-trauma were reported in five cats, with tail mutilation in four cats. Vocalisation during the episodes (n = 5) and rippling of lumbar skin (n = 5) were also reported. Haematology, serum biochemistry, Toxoplasma gondii and feline immunodeficiency virus/feline leukaemia virus serology, MRI scans of brain, spinal cord and cauda equina, cerebrospinal fluid analysis and electrodiagnostic tests did not reveal any clinically significant abnormalities. A definitive final diagnosis was not reached in any of the cats, but hypersensitivity dermatitis was suspected in two cases. A variety of medications was used alone or in combination, including gabapentin (n = 6), meloxicam (n = 4) antibiotics (n = 4), phenobarbital (n = 2), prednisolone (n = 2) and topiramate (n = 2); ciclosporin, clomipramine, fluoxetine, amitriptyline and tramadol were used in one cat each. Clinical improvement was achieved in six cases; in five cats complete remission of clinical signs was achieved with gabapentin alone (n = 2), a combination of gabapentin/ciclosporin/amitriptyline (n = 1), gabapentin/prednisolone/phenobarbital (n = 1) or gabapentin/topiramate/meloxicam (n = 1). Relevance and novel information This is the first retrospective study on a series of cats with FHS. The diagnostic work-up did not reveal any significant abnormalities of the central or peripheral nervous system; dermatological and behavioural problems could not be ruled out. We propose an integrated multidisciplinary diagnostic pathway to be used for the management of clinical cases and for future prospective studies.

AB - Objective This study aimed to assess the diagnostic value of serum neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C for renal dysfunction in older patients with coronary disease. Methods A total of 84 older patients with coronary artery disease were included in this study. Serum NGAL and cystatin C levels were analysed using commercially available kits. Medical data of all patients were recorded and analysed. Results NGAL and cystatin C levels were significantly positively correlated with N-terminal prohormone of brain natriuretic peptide levels and negatively correlated with the estimated glomerular filtration rate. The areas under the receiver operating characteristic curves of serum NGAL and cystatin C levels for diagnosing early renal dysfunction were 0.884 and 0.744, respectively. Conclusion Serum NGAL and cystatin C are potential early and sensitive markers of renal dysfunction in older patients with coronary artery disease. PMID- 29595361 TI - Positive-blank versus negative-blank feedback learning in children and adults. AB - In positive-blank feedback learning, positive feedback is given to a correct response whereas blank feedback is given to an incorrect response. Conversely, in negative-blank feedback learning, blank feedback is given to a correct response and negative feedback to an incorrect response. As blank feedback might be subjectively interpreted as signalling a correct response, negative-blank feedback might be more informative than positive-blank feedback, and thus may result in better performance. However, positive-blank feedback might also be superior as it motivates the learner in lengthy tasks. These "information" and "motivation" accounts were tested in a two-block feedback learning paradigm. In the first block, that is, when the task duration was still short, children but not adults profited more from negative than from positive feedback. The results in children thus support the information account. In the second block, that is, when the task duration had become longer, children and adults profited more from positive feedback, thereby supporting the motivation account. Results are discussed in light of behavioural and neuroscientific theories on feedback learning. PMID- 29595362 TI - The framing effect in a monetary gambling task is robust in minimally verbal language switching contexts. AB - Decision-making biases, in particular the framing effect, can be altered in foreign language settings (foreign language effect) and following switching between languages (the language switching effect on framing). Recently, it has been suggested that the framing effect is only affected by foreign language use if the task is presented in a rich textual form. Here, we assess whether an elaborate verbal task is also a prerequisite for the language switching effect on framing. We employed a financial gambling task that induces a robust framing effect but is less verbal than the classical framing paradigms (e.g., the Asian disease problem). We conducted an online experiment ( n = 485), where we orthogonally manipulated language use and language switching between trials. The results showed no effects of foreign language use or language switching throughout the experiment. This online result was confirmed in a laboratory experiment ( n = 27). Overall, we find that language switching does not reduce the framing effect in a paradigm with little verbal content and thus that language switching effects seem contingent on the amount of verbal processing required. PMID- 29595363 TI - Emotion identification across adulthood using the Dynamic FACES database of emotional expressions in younger, middle aged, and older adults. AB - Facial stimuli are widely used in behavioural and brain science research to investigate emotional facial processing. However, some studies have demonstrated that dynamic expressions elicit stronger emotional responses compared to static images. To address the need for more ecologically valid and powerful facial emotional stimuli, we created Dynamic FACES, a database of morphed videos (n = 1026) from younger, middle-aged, and older adults displaying naturalistic emotional facial expressions (neutrality, sadness, disgust, fear, anger, happiness). To assess adult age differences in emotion identification of dynamic stimuli and to provide normative ratings for this modified set of stimuli, healthy adults (n = 1822, age range 18-86 years) categorised for each video the emotional expression displayed, rated the expression distinctiveness, estimated the age of the face model, and rated the naturalness of the expression. We found few age differences in emotion identification when using dynamic stimuli. Only for angry faces did older adults show lower levels of identification accuracy than younger adults. Further, older adults outperformed middle-aged adults' in identification of sadness. The use of dynamic facial emotional stimuli has previously been limited, but Dynamic FACES provides a large database of high resolution naturalistic, dynamic expressions across adulthood. Information on using Dynamic FACES for research purposes can be found at http://faces.mpib berlin.mpg.de . PMID- 29595364 TI - Associations of alcohol use disorder, alcohol use, housing, and service use in a homeless sample of 255 individuals followed over 2 years. AB - BACKGROUND: Homeless individuals with alcohol use disorders have multiple comorbidities and therefore various service needs. Despite need for services, homeless individuals face numerous barriers to treatment. Little is known about the associations of specific services in relation to homelessness in the context of alcohol problems. The current study analyzed 2-year prospective longitudinal data on a homeless sample, examining relationships between alcohol use disorder, alcohol use, housing status, and service use over time. METHODS: Two hundred fifty-five of 400 individuals recruited systematically from shelters and street locations completed 3 annual assessments (69% completion). Data on lifetime and current psychiatric disorders, housing status, and past-year service use were obtained and merged with service use data gathered from local agencies. Generalized estimating equation (GEE) models were created to predict dependent outcome variables of stable housing, alcohol use, and service use in both follow up years. RESULTS: Lifetime alcohol use disorder was positively associated with substance and medical service use. Alcohol problems did not hinder attainment of stable housing, and placement in housing did not necessarily increase risk for alcohol use. Stable housing was negatively associated with psychiatric and substance service use. In the second year, when alcohol use was finally associated with receiving substance services, it appears that these services provided a gateway to psychiatric services. The psychiatric services in turn appeared to provide a gateway to medical services. CONCLUSIONS: Alcohol use behaved differently compared with lifetime alcohol use disorder in relation to service use. Lack of association between alcohol use and housing supports Housing First policy. Obtaining housing may have ameliorative effects on mental health, diminishing perceived need for psychiatric services. Services may also be more accessible during homelessness. Obtaining substance treatment may provide a gateway for those who use alcohol after becoming homeless to connect with psychiatric and medical services, informing policy and practice.

AB - Mutations in the BRAF oncogene are found in 2-4% of all non-small cell lung cancer (NSCLC) patients. The most common activating mutation present within the BRAF oncogene is associated with valine substitution for glutamate at position 600 (V600E) within the BRAF kinase. BRAF-targeted therapies are effective in patients with melanoma and NSCLC harboring BRAF V600E mutation. In both melanoma and NSCLC, dual inhibition of both BRAF and the downstream mitogen-activated protein kinase (MEK) improves response rates compared with BRAF inhibition alone. BRAF-MEK combination therapy (dabrafenib plus trametinib) demonstrated tolerability and efficacy in a recent phase II clinical trial and was approved by the European Medicines Agency and United States Food and Drug Administration for patients with stage IV NSCLC harboring BRAF V600E mutation. Here, in this review, we outline the preclinical and clinical data for BRAF and MEK inhibitor combination treatment for NSCLC patients with BRAF V600E mutation. PMID- 29595367 TI - Lessons learned from the implementation of a medically enhanced residential treatment (MERT) model integrating intravenous antibiotics and residential addiction treatment. AB - BACKGROUND: Hospitalizations for severe infections associated with substance use disorder (SUD) are increasing. People with SUD often remain hospitalized for many weeks instead of completing intravenous antibiotics at home; often, they are denied skilled nursing facility admission. Residential SUD treatment facilities are not equipped to administer intravenous antibiotics. We developed a medically enhanced residential treatment (MERT) model integrating residential SUD treatment and long-term IV antibiotics as part of a broader hospital-based addiction medicine service. MERT had low recruitment and retention, and ended after six months. The goal of this study was to describe the feasibility and acceptability of MERT, to understand implementation factors, and explore lessons learned. METHODS: We conducted a mixed-methods evaluation. We included all potentially eligible MERT patients, defined by those needing >=2 weeks of intravenous antibiotics discharged from February 1 to August 1, 2016. We used chart review to identify diagnoses, antibiotic treatment location, and number of recommended and actual IV antibiotic-days completed. We audio-recorded and transcribed key informant interviews with patients and staff. We conducted an ethnographic analysis of interview transcripts and implementation field notes. RESULTS: Of the 45 patients needing long-term intravenous antibiotics, 18 were ineligible and 20 declined MERT. 7 enrolled in MERT and three completed their recommended intravenous antibiotic course. MERT recruitment barriers included patient ambivalence towards residential treatment, wanting to prioritize physical health needs, and fears of untreated pain in residential. MERT retention barriers included high demands of residential treatment, restrictive practices due to PICC lines, and perceptions by staff and other residents that MERT patients "stood out" as "different." Despite the challenges, key informants felt MERT was a positive construct. CONCLUSIONS: Though MERT had many possible advantages; it proved more challenging to implement than anticipated. Our lessons may be applicable to future models integrating post-hospital intravenous antibiotics and SUD care. PMID- 29595369 TI - Corrigendum. PMID- 29595368 TI - The care of patients using methamphetamine in the emergency department: Perception of nurses, residents, and faculty. AB - BACKGROUND: To determine differences in perception between nurses, residents, and faculty regarding characteristics and treatment of patients who use methamphetamine (meth). METHODS: Survey study performed at an urban, university Level I trauma medical center. RESULTS: A total of 80 nurses, 39 residents, and 45 faculty completed the survey. All groups agreed that meth was a significant problem nationwide and in our emergency department (ED). Nurses estimated that 33% of their patients used meth, which differed from residents (18%) and faculty (15%). All agreed that these patients required more effort to care for, utilized more hospital resources, and were more often violent toward staff. Nurses reported higher prevalence of actual assault by patients using meth (70%) than did residents (36%) and faculty (47%), and total lifetime number of assaults. All agreed that patients using meth appropriated prehospital resources at a higher rate than nonusers, had a higher rate of recidivism, and longer ED length of stay. Nurses preferred antipsychotics over benzodiazepines for treatment of meth induced tachycardia and a lower threshold for treatment of associated hypertension than residents and faculty. For treatment of hypertension, nurses preferred beta-blockers and hydralazine over benzodiazepines. CONCLUSION: All agreed that meth use is a serious problem in our ED, with high resource utilization, recidivism, and violence against staff. Nurses experienced higher rates of assaults by patients using meth and differed with regard to their disposition and treatment. Treatment guidelines, strategies to mitigate violence towards staff, and interprofessional education may be beneficial, as the stakes of caring for these patients are high and preferences vary between caregivers. PMID- 29595370 TI - Social work students' service learning experiences with grandfamilies: contact, comfort, and attitudes. AB - One way to increase student learning about older adults and aging family issues is to engage in community-based field experiences. Results from pre- and post surveys with 29 Bachelors of Social Work students enrolled in a year-long practicum course to assess their change in the level of contact, comfort, and attitudes with older adults and grandfamilies (i.e., grandparents/kin and the children in their home) are discussed. Students who met with grandfamilies (n = 9) were compared to students who met with older adults in a nursing home (n = 6) and students who met with children from an afterschool program or child treatment facility (n = 9). One-way ANOVA's revealed group differences in contact and quality of contact with grandfamilies. No significant differences were found for contact with older adults or comfort working with older adults and grandfamilies, or for attitudes toward older adults between the three groups. As a result of this project, educators should develop learning opportunities for students to increase their contact and comfort with older adults and aging families. PMID- 29595371 TI - Pathways to age-friendly communities in diverse urban neighborhoods: Do social capital and social cohesion matter? AB - Using a social capital and social cohesion lens, we reposition the concept of civic engagement among older adults to examine pathways for building age-friendly communities. We analyzed data drawn from a Community-Based Participatory Research study in the Southern U.S. that explored lived experiences of older adults, age 55 and above, who participated in individual interviews (n = 15) and six focus group discussions (n = 45) to examine their perceptions of social identity, social connectedness, and civic engagement geared toward an age-friendly city. Findings indicated that several older adults had access to social networks and socially invested resources, thereby having opportunities for civic engagement and building age-friendly neighborhoods. However, social, cultural, linguistic, and structural barriers were more evident among certain diverse ethnic populations. Marginalized low-income minorities and immigrants, such as Hispanic participants, felt the lack of social cohesion among the larger society limited their ability to give back, thus decreasing their civic engagement activities. In contrast, Caucasian and African-American older adults were able to contribute to the political process through more civic participation activities. We provide implications for examining the role of social capital and social engagement to bolster civic engagement among older adults in building age-friendly communities.

AB - The Arctic populations have high blood concentrations of persistent organic pollutants (POPs). Exposure to POPs was related to adverse health effects e.g. immune, neurological and reproductive systems. This study investigates associations between serum POP levels and haematological markers in Greenlandic pregnant women. This cross-sectional study included 189 women enrolled in 2010 2011 at the Greenlandic West coast by the inclusion criteria >=18 years of age and had lived for 50% or more of their life in Greenland. The associations between the sum of the POP variables polychlorinated biphenyls (sumPCBs), organochlorine pesticides (sumOCPs), perfluoroalkylated substances (sumPFASs) and 24 haematological markers were analysed using linear regression adjusted for age, pre-pregnancy BMI, parity, gestation week, plasma-cotinine and alcohol intake. It showed a significantly inverse association between several haematological markers (eosinophil, lymphocyte, neutrophil and white blood cells) and sumPCBs, sumOCPs and sumPFASs. In addition, the monocyte, mean corpuscular haemoglobin concentration, plateletcrit and platelet count markers were significantly inversely associated with sumPFASs, but the haematocrit and mean erythrocyte corpuscular volume were positively associated with sumPFASs. In conclusion, exposure to POPs influenced several haematological markers, especially cell count parameters, suggesting immunosuppressive potential of POPs in Greenlandic pregnant women. The data need further investigations. PMID- 29595374 TI - Procedures and complications in late-nineteenth-century experimental neuroanatomical research exemplified by articles of Henry Herbert Donaldson (1857 1938). AB - Henry Herbert Donaldson (1857-1938) was a leader in neurological research in the United States for several decades, beginning about 1890. A detailed account of three of his earliest publications shows the neuroanatomical procedures involved in the study of the relation of brain and intelligence during the late-nineteenth century in America. Two of the articles, published in September 1890 and December 1891, were titled, "Anatomical Observations on the Brain and Several Sense-Organs of the Blind Deaf-Mute, Laura Dewy Bridgman (1829-1889)"; the third, published in August 1892, used the information from the first two to delimit the extent of the visual processing area of the human cortex. Donaldson's procedures included brain cuttings and measures of macroscopic brain structures, histology of cellular structures, attempts to relate macroscopic brain structures with brain functions, data corrections, estimations, comparisons, and statistics. These procedures provide a view of the relative thoroughness, accuracy, and comparability of the various neuroanatomical techniques in use at that time and of Donaldson's implementation of the techniques. Donaldson's brain cutting techniques were much more comparable than his measurement techniques. The latter could be quite precise, but they were fraught with lack of standardized procedures that made corrections and estimations necessary when making data comparisons across studies. Donaldson emphasized these incompatibilities, implying a need for standardization. Statistical procedures were the least thorough and effective. His, and the field's, total complement of statistical techniques consisted of mean and range, which severely limited his ability to make complicated assessments. This limitation was not necessarily supplemented by stringent control group comparisons. PMID- 29595375 TI - Medications for Opioid Use Disorder in the Department of Veterans Affairs (VA) Health Care System: Historical Perspective, Lessons Learned and Next Steps. AB - The US Department of Veterans Affairs (VA), the largest health care system in the US, has been confronted with the health care consequences of opioid disorder (OUD). Increasing access to quality OUD treatment, including pharmacotherapy, is a priority for the VA. We examine the history of medications (e.g., methadone, buprenorphine, injectable naltrexone) used in the treatment of OUD within VA, document early and ongoing efforts to increase access and build capacity, primarily through the use of buprenorphine, and summarize research examining barriers and facilitators to prescribing and medication receipt. We find that there has been a slow but steady increase in the use of medications for OUD and, despite system-wide mandates and directives, uneven uptake across VA facilities and within patient sub-populations, including some of those most vulnerable. We conclude with recommendations intended to support the greater use of medication for OUD in the future, both within VA as well as other large health care systems. PMID- 29595376 TI - Application of an Ex Vivo Tissue Model to Investigate Radiobiological Effects on Spermatogenesis. AB - The formation of sperm by the testes through the process of spermatogenesis is highly radiosensitive and can be affected by environmental, occupational and therapeutic radiation exposures. In this study, we applied an ex vivo mouse testis organ culture as an experimental model of spermatogenesis to investigate the radiobiological effects and to demonstrate its feasibility as a tool to determine response to complex, modulated radiation fields. This model uses Acr GFP transgenic mice, which express the marker green fluorescent proteins specific for meiosis to allow observation of functional changes in real-time that can be used to analyze radiation-induced changes in the process of spermatogenesis. Our results showed that the model can accurately reproduce radiation-induced male germ cell toxicity, such as temporary infertility and permanent sterility. Furthermore, using a monochromatic X-ray microbeam, we applied this model to investigate the effects of heterogeneous radiation fields on testis tissue ex vivo. Our model represents a unique application in the field, which offers significant potential for gaining further mechanistic insight into radiation effects on the process of spermatogenesis. PMID- 29595377 TI - Procrastination, Flow, and Academic Performance in Real Time Using the Experience Sampling Method. AB - The authors' aim was to first provide an alternative methodology in the assessment of procrastination and flow that would not reply on retrospective or prospective self-reports. Using real-time assessment of both procrastination and flow, the authors investigated how these factors impact academic performance by using the Experience Sampling Method. They assessed flow by measuring student self-reported skill versus challenge, and procrastination by measuring the days to completion of an assignment. Procrastination and flow were measured for six days before a writing assignment due date while students (n = 14) were enrolled in a research methods course. Regardless of status of flow, both the nonflow and flow groups showed high levels of procrastination. Students who experienced flow as they worked on their paper, in real time, earned significantly higher grades (M = 3.05 +/- 0.30: an average grade of B) as compared with the nonflow group (M = 1.16 +/- 0.33: an average grade of D; p = .007). Additionally, students experiencing flow were more accurate in predicting their grade (difference scores, flow M = 0.12 +/- 0.33 vs. nonflow M = 1.39 +/- 0.29; p = .015). Students in the nonflow group were nearly a grade and a half off in their prediction of their grade on the paper. To the authors' knowledge, the study is the first to provide experimental evidence showing differences in academic performance between students experiencing flow and nonflow students. PMID- 29595378 TI - A systematic review of work-related musculoskeletal disorders among handicraft workers. AB - PURPOSE: Handicraft manufacturing appears to be an occupation where work-related musculoskeletal disorders (WMSDs) are a major threat to workers. For the multifactorial nature and varying prevalence of WMSDs between different body areas, the current study aimed to evaluate the prevalence of WMSDs and associated risk factors among handicraft workers. METHODS: This review was based on literature collected from three electronic databases, and the retrieved articles were screened following the inclusion/exclusion criteria. After applying the literature selection criteria to 182 articles, 30 citations were selected and examined in detail. RESULTS: The findings suggest that the prevalence of musculoskeletal symptoms among handicraft workers is 38.5-100%, and the most affected body areas were the neck, back, knees and upper limbs. Risk factors including working posture, daily working hours, repetitive and forceful movements, work experience, age, gender and working under stressful conditions were found to be highly associated with the occurrence of WMSDs. However, higher educational qualification of the workers led to a reduction in the odds of developing WMSDs. CONCLUSION: Handicraft workers are at high risk of developing WMSDs. Further research, preferably longitudinal studies, with more emphasis on work-related factors should now be undertaken to thoroughly investigate WMSDs in this occupational group. PMID- 29595379 TI - Child malnutrition in Ifanadiana district, Madagascar: associated factors and timing of growth faltering ahead of a health system strengthening intervention. AB - BACKGROUND: Child malnutrition, a leading cause of death and disability worldwide, is particularly severe in Madagascar, where 47% of children under 5 years are stunted (low height-for-age) and 8% are wasted (low weight-for-height). Widespread poverty and a weak health system have hindered attempts to implement life-saving malnutrition interventions in Madagascar during critical periods for growth faltering. OBJECTIVE: This study aimed to shed light on the most important factors associated with child malnutrition, both acute and chronic, and the timing of growth faltering, in Ifanadiana, a rural district of Madagascar. METHODS: We analyzed data from a 2014 district-representative cluster household survey, which had information on 1175 children ages 6 months to 5 years. We studied the effect of child health, birth history, maternal and paternal health and education, and household wealth and sanitation on child nutritional status. Variables associated with stunting and wasting were modeled separately in multivariate logistic regressions. Growth faltering was modeled by age range. All analyses were survey-adjusted. RESULTS: Stunting was associated with increasing child age (OR = 1.03 (95%CI 1.02-1.04) for each additional month), very small birth size (OR = 2.32 (1.24-4.32)), low maternal weight (OR = 0.94 (0.91-0.97) for each kilogram, kg) and height (OR = 0.95 (0.92-0.99) for each centimeter), and low paternal height (OR = 0.95 (0.92-0.98)). Wasting was associated with younger child age (OR = 0.98 (0.97-0.99)), very small birth size (OR = 2.48 (1.23 4.99)), and low maternal BMI (OR = 0.84 (0.75-0.94) for each kg/m2). Height-for age faltered rapidly before 24 months, then slowly until age 5 years, whereas weight-for-height faltered rapidly before 12 months, then recovered gradually until age 5 years but did not reach the median. CONCLUSION: Intergenerational transmission of growth faltering and early life exposures may be important determinants of malnutrition in Ifanadiana. Timing of growth faltering, in the first 1000 days, is similar to international populations; however, child growth does not recover to the median. PMID- 29595380 TI - EVALUATION OF ORAL RABIES VACCINATION: PROTECTION AGAINST RABIES IN WILD CAUGHT RACCOONS ( PROCYON LOTOR). AB - Oral rabies vaccination (ORV) is an effective tactic for wildlife rabies control, particularly for containment of disease spread along epizootic fronts. As part of the continuing evaluation of the ORV program in free-ranging raccoons ( Procyon lotor) in the US, 37 raccoons from ORV-baited areas in Pennsylvania were live trapped and transferred to captivity to evaluate protection against rabies in animals with varying levels of existing neutralizing antibodies, expressed in international units per milliliter (IU/mL). Among the 37 raccoons at the date of capture, 24% (9/37) of raccoons were seronegative (<0.05 IU/mL), 22% (8/37) were low positive (>=0.05-0.11 IU/mL), 27% (10/37) were medium positive (>0.11-<0.5 IU/mL), and 27% (10/37) were high positive (>=0.5 IU/mL). Raccoons were held for 86-199 d between the date of capture and rabies virus challenge. At challenge, 68% (25/37) raccoons were seronegative. The overall survival rate among challenged animals was 46% (17/37). Based on the antibody titers at the time of challenge, survivorship was 24% (6/25) among seronegative animals, 100% (4/4) among low positive animals, 83% (5/6) among medium positive animals, and 100% (2/2) among high positive animals. Evidence of high-titer seroconversion after vaccination is a good surrogate indicator of rabies survival; however, survival rates of approximately 45% (15/35) were found among raccoons with detectable titers below 0.5 IU/mL. In contrast, any detectable titer at the time of challenge (>3 mo after vaccination) appeared to be a surrogate indicator of survival. Overall, we illustrated significant differences in the value of specific titers as surrogates for survival based on the timing of measurement relative to vaccination. However, survivorship was generally greater than 45% among animals with any detectable titer regardless of the timing of measurement. These findings suggest that lower titer cutoffs may represent a valid approach to measuring immunization coverage within ORV management zones, balancing both sensitivity and specificity for estimating herd immunity. PMID- 29595381 TI - Phylogenetic Analysis of Pigeon Paramyxoviruses Type-1 Identified in Mourning Collared-doves ( Streptopelia decipiens) in Namibia, Africa. AB - We generated the complete sequence of the fusion ( F) protein gene from six pigeon paramyxoviruses type 1 (PPMV-1) isolated from Mourning Collared-doves ( Streptopelia decipiens) in Namibia, Africa between 2016 and 2017. All of the isolates had an F gene cleavage site motif of 112RRQKRF117 characteristic of virulent viruses. A phylogenetic analysis using the full F gene sequence revealed that the viruses belonged to genotype VIa and were epidemiologically related to PPMV-1s from Asia, Europe, and North America. PMID- 29595382 TI - Identification of Novel Gammaherpesviruses in a South American Fur Seal ( Arctocephalus australis) with Ulcerative Skin Lesions. AB - There are few studies on pathogens affecting free-ranging pinnipeds from South America. We employed molecular techniques to identify a gammaherpesvirus infection by two putative novel herpesvirus species: Otariid herpesvirus 5 (OtHV 5), possibly associated with ulcerative cutaneous lesions, and Otariid herpesvirus 6 (OtHV-6) in a wild South American fur seal ( Arctocephalus australis) that stranded alive in Santa Catarina state, southern Brazil. Here we provide new information regarding pinniped herpesviruses, important for the design of future disease surveillance studies. PMID- 29595383 TI - Mesocestoides sp. in Wild Northern Bobwhite ( Colinus virginianus) and Scaled Quail ( Callipepla squamata). AB - Mesocestoides spp. have a cosmopolitan distribution with zoonotic potential. Mesocestoides tetrathyridia were found under the pericardial sac, on the surface of the crop, and in the peritoneal cavity of a hunter-harvested Northern Bobwhite ( Colinus virginianus) and a Scaled Quail ( Callipepla squamata) collected during the 2016-17 quail hunting season in northwest and southern Texas, US respectively. Molecular analysis indicated that the tetrathyridia from the birds likely belonged to an undescribed species and are identical to pretetrathyridium stages recently found in Scincella lateralis skinks in Oklahoma. This is the first report of Mesocestoides from North American birds. PMID- 29595385 TI - Letters to the Editor. PMID- 29595384 TI - What Is Your Diagnosis? PMID- 29595386 TI - Outcomes of and risk factors for presumed canine H3N2 influenza virus infection in a metropolitan outbreak. AB - OBJECTIVE To determine clinical signs, case fatality rate, and factors associated with positive results of PCR testing for canine influenza virus (CIV) in dogs during an H3N2 CIV outbreak in the Atlanta area. DESIGN Cross-sectional study. ANIMALS 220 dogs with a nasal swab specimen submitted to an Atlanta-area diagnostic laboratory between May 1 and July 2, 2015, for PCR assay detection of CIV specifically or CIV and 5 other respiratory pathogens. PROCEDURES Veterinarians of tested dogs were surveyed by various means to collect information regarding clinical signs, survival status at the time of survey completion, vaccination history (<= 12 months prior to testing), and travel history (<= 2 months prior to testing). Data were compared between CIV-positive and CIV-negative dogs. RESULTS Surveys for 120 (55%) dogs were completed. Forty (33%) of these dogs had positive results of CIV testing. No significant differences were identified between CIV-positive and CIV-negative dogs regarding breed, sex, reproductive status, duration of clinical signs prior to testing, other dogs in the household, or travel history. When other factors were controlled for, CIV-positive dogs were more likely to be adult (> 1 year of age) than juvenile (<= 1 year of age) and to be inappetent. Only 1 (3%) CIV-positive dog died during the study period (shortly after it was evaluated because of respiratory signs). CONCLUSIONS AND CLINICAL RELEVANCE From May 1 to July 2, 2015, the reported clinical signs of dogs tested during the Georgia H3N2 CIV outbreak were similar to those reported for dogs with H3N8 CIV infection, and the case fatality rate was low.

AB - OBJECTIVE To describe rabies and rabies-related events occurring during 2016 in the United States. DESIGN Observational study based on passive surveillance data. ANIMALS All animals submitted for rabies testing in the United States during 2016. PROCEDURES State and territorial public health programs provided data on animals submitted for rabies testing in 2016. Data were analyzed temporally and geographically to assess trends in domestic and sylvatic animal rabies cases. RESULTS During 2016, 50 states and Puerto Rico reported 4,910 rabid animals to the CDC, representing a 10.9% decrease from the 5,508 rabid animals reported in 2015. Of the 4,910 cases of animal rabies, 4,487 (91.4%) involved wildlife. Relative contributions by the major animal groups were as follows: 1,646 (33.5%) bats, 1,403 (28.6%) raccoons, 1,031 (21.0%) skunks, 313 (6.4%) foxes, 257 (5.2%) cats, 70 (1.4%) cattle, and 58 (1.2%) dogs. There was a 4.6% decrease in the number of samples submitted for testing in 2016, compared with the number submitted in 2015. No human rabies deaths were reported in 2016. CONCLUSIONS AND CLINICAL RELEVANCE Laboratory testing of animals suspected to be rabid remains a critical public health function and continues to be a cost-effective method to directly influence human rabies postexposure prophylaxis recommendations.

AB - OBJECTIVE To determine the frequency and complexity of ventricular arrhythmias in a group of healthy Salukis evaluated by means of continuous Holter monitoring for 7 days. DESIGN Prospective case series. ANIMALS 25 healthy Salukis > 18 months old. PROCEDURES In all dogs, a history was obtained and a physical examination and transthoracic echocardiography were performed to verify the absence of structural cardiac disease. Dogs then underwent Holter monitoring for 7 days. Data recorded included heart rate parameters and the occurrence of conduction disturbances, ventricular premature complexes, ventricular couplets, ventricular triplets, ventricular bigeminy, ventricular trigeminy, and ventricular tachycardia. RESULTS 25 dogs (13 sexually intact females, 2 spayed females, and 10 sexually intact males) were enrolled in the study. All 25 dogs had at least one 24-hour period during which ventricular premature complexes were detected. Median number of ventricular premature complexes during any 24-hour period in all dogs was 2 (interquartile [25th to 75th percentile] range, 0 to 4). There were no significant differences between males and females in regard to median number of ventricular premature complexes per 24-hour period or recorded heart rate parameters. CONCLUSIONS AND CLINICAL RELEVANCE For Salukis in the study population, 7-day Holter monitoring revealed infrequent ventricular arrhythmias. These findings suggested that detection of a ventricular arrhythmia in a healthy Saluki may be an indication for further diagnostic evaluation.

PMID- 29595394 TI - Comparison of thoracic duct ligation plus subphrenic pericardiectomy with or without cisterna chyli ablation for treatment of idiopathic chylothorax in cats. AB - OBJECTIVE To compare duration of surgery, recurrence rate, and survival time between cats with idiopathic chylothorax treated with thoracic duct ligation (TDL) plus subphrenic pericardiectomy (SPC) and those treated with TDL, SPC, and cisterna chyli ablation (CCA). DESIGN Retrospective case series with nested cohort study. ANIMALS 22 client-owned cats surgically treated for idiopathic chylothorax from 2009 through 2014. PROCEDURES Patient and surgery data were collected from the medical records. Recurrence of chylothorax and survival time were assessed by medical record review and client interview. Comparisons were made between cats treated with TDL plus SPC (TDL-SPC group) and those treated with TDL, SPC, and CCA (TDL-SPC-CCA group). RESULTS 15 cats were treated with TDL plus SPC, and 7 were treated with TDL, SPC, and CCA. Median duration of surgery was significantly briefer for the TDL-SPC group (80 minutes; range, 55 to 175 minutes) than for the TDL-SPC-CCA group (125 minutes; range, 105 to 205 minutes). Five cats (2 in the TDL-SPC group and 3 in the TDL-SPC-CCA group) had persistent pleural effusion 4 weeks after surgery. Chylothorax recurred in 2 cats (1/group). Median survival time in the TDL-SPC group was 774 days (range, 3 to 2,844 days) and in the TDL-SPC-CCA group was 380 days (range, 11 to 815 days); these values did not differ significantly. CONCLUSIONS AND CLINICAL RELEVANCE Addition of CCA to the surgical treatment approach for cats with idiopathic chylothorax was associated with a significantly longer duration of surgery with no better outcome than achieved with TDL plus SPC alone.

AB - OBJECTIVE To describe clinical findings and diagnostic test results and identify potential prognostic indicators for calves with septic arthritis. DESIGN Retrospective case series. ANIMALS 64 calves with septic arthritis. PROCEDURES The medical record database for a veterinary teaching hospital was searched to identify calves <= 6 months old that were treated for septic arthritis between 2009 and 2014. Data evaluated included signalment, history, physical examination and diagnostic test results, treatment, and outcome. Descriptive data were generated, and calves were assigned to 2 groups (neonatal [<= 28 days old] or postneonatal [29 to 180 days old]) on the basis of age at hospital admission for comparison purposes. RESULTS 64 calves had 92 infected joints; 17 calves had polyarthritis. Carpal joints were most frequently affected followed by the stifle and tarsal joints. Forty-nine bacterial isolates were identified from synovial specimens for 38 calves, and the most commonly identified isolates were catalase negative Streptococcus spp (n = 14) and Mycoplasma bovis (9). Calves in the neonatal group had a shorter interval between onset of clinical signs and hospitalization and were more likely to have an infected carpal joint than calves in the postneonatal group. Outcome was positive for 35 calves. Synovial fluid total nucleated cell count was positively associated with a positive outcome. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that empirical antimicrobial treatment for calves with septic arthritis should target gram-positive catalase negative cocci and M bovis and that synovial fluid total nucleated cell count might be a useful prognostic indicator. PMID- 29595397 TI - Rostral mandibular fracture repair in a pet bearded dragon (Pogona vitticeps). AB - CASE DESCRIPTION A 2-year-old male bearded dragon (Pogona vitticeps) was evaluated because of a traumatic mandibular fracture. CLINICAL FINDINGS An open comminuted fracture of the rostral aspect of the right mandible was evident, with a fragment of bone exposed and dorsally displaced. Whole-body radiography revealed no evidence of additional injury. Other findings were unremarkable, except for moderate anemia (PCV, 19%). TREATMENT AND OUTCOME The fracture fragments were stabilized with 2 crossed 36-gauge interfragmentary wire loops. An external fixator device was fashioned from four 25-gauge needles inserted at alternating angles through the fracture fragments; plastic IV fluid line tubing filled with dental acrylic was used as a connecting bar. One day after surgery, the lizard had regained its typical activity level and appetite. Body weight was measured and the external fixator was inspected 1 week after surgery and monthly thereafter. Three months after initial injury, the fracture was stable, radiography revealed bony callus formation at the fracture site, and the external fixator was removed. Recheck radiography performed 5.5 months after initial injury revealed complete osseous union of the fracture fragments, and the interfragmentary wires were removed. CLINICAL RELEVANCE Surgical management of the traumatic comminuted mandibular fracture in this bearded dragon by means of a combination of internal and external fixation resulted in complete healing of the mandible and restoration of function. Management of this complicated fracture was achieved with the aid of readily available and inexpensive supplies in a clinical setting, which may be useful to other clinicians in the management of similar cases. PMID- 29595398 TI - Outcome of elective cholecystectomy for the treatment of gallbladder disease in dogs. AB - OBJECTIVE To determine mortality rates for dogs undergoing cholecystectomy and variables associated with failure to survive to hospital discharge. DESIGN Retrospective cohort study. ANIMALS 70 dogs that underwent cholecystectomy for biliary tract disease at a companion animal referral hospital from 2009 through 2015. PROCEDURES Medical records of dogs were reviewed and data collected; dogs with biliary diversion surgery were excluded. Included dogs were grouped by whether cholecystectomy had been elective (ie, dogs with no or mild clinical signs, with no indication of biliary obstruction, or that initially underwent surgery for a different procedure) or nonelective (ie, dogs with icterus and questionable patency of the biliary system). Mortality rates (proportions of dogs that failed to survive to hospital discharge) were compared between various groups. RESULTS 45 (64%) dogs were included in the elective group and 25 (36%) in the nonelective group. Group mortality rates were 2% (1/45) and 20% (5/25), respectively, and differed significantly. Overall mortality rate was 9% (6/70). Serum albumin concentration was significantly lower and serum alanine aminotransferase activity and total bilirubin concentration were significantly higher in nonsurviving versus surviving dogs. Dogs with vomiting, signs of lethargy or anorexia, icterus, or azotemia were less likely to survive than dogs without these signs. CONCLUSIONS AND CLINICAL RELEVANCE Dogs that underwent elective cholecystectomy had a considerably lower mortality rate than previously reported. Elective cholecystectomy may be an appropriate recommendation for dogs with early signs of biliary disease to avoid the greater mortality rate associated with more advanced disease and nonelective cholecystectomy. PMID- 29595399 TI - Functionality of a novel follitropin alfa pen injector: results from human factor interactions by patients and nurses. AB - OBJECTIVE: The main objective of this user experience testing study was to evaluate the impact of human factors on the use of a disposable pen containing follitropin alfa by patients and nurses with special focus on the convenience, safety and ease of use, in different types of stimulation protocols. METHODS: Infertile women trying to conceive, and specialist nurses were recruited across 6 European countries. In total 18 patients and 19 nurses took part in the testing, which included both nurse-patient pairings and in-depth interviews. A standardized list of expected and pre-defined critical steps according to the Instructions for Use (IFU), was used to assess the correct handling of the pen. RESULTS: During the user experience testing, no critical errors, related to the use of the pen, which could affect the success of the injection process were identified. In general, both nurses and patients found the pen very easy to learn, use and would be confident using the pen for self-injection. Nurses also found the pen very easy to train the patients. CONCLUSIONS: The study provides valuable information on the pen from both patient and nurse perspectives in different simulated scenarios reflecting standard practice. PMID- 29595400 TI - Lack of knowledge and training are the major obstacles in application of the Spinal Cord Independence Measure (SCIM) in China. AB - Objective To investigate the use of functional outcome measurements after spinal cord injury (SCI) in current clinical practice and to explore the knowledge about the Spinal Cord Independence Measure (SCIM) among SCI physicians in China, and to find facilitators for a broader utilization of SCIM. Design A survey-based study. Setting SCI workshops at Peking University. Participants 125 Chinese SCI physicians attending annual workshops in two consecutive years. Interventions Not applicable. Outcome measures A questionnaire was administered. The following items were included: whether functional outcome measurement for SCI individuals was performed and with which assessment tool(s); what items should be included in the assessment; whether they knew about the SCIM, its latest version, the Chinese translation, and if so from what source; the possible reasons why SCIM was not implemented in clinical practice; and whether training before using the SCIM was needed, and the training method preferred. Results Among these physicians, 84.8% performed functional outcome measurement for individuals with SCI, but only 29.6% of attendees were aware of the SCIM and 20.8% had used it. Lack of training was the major reason why SCIM was not used in clinical practice. Furthermore, 74.4% of the physicians felt they needed formal training before using the SCIM. Conclusion The use of SCIM is limited in clinical practice in China, which is mainly attributed to lack of knowledge and training. Formal training on the use of the SCIM is essential for its dissemination and will improve functional SCI outcome measurement in China. PMID- 29595401 TI - Epidemiological profile of thoracolumbar fracture (TLF) over a period of 10 years in Tianjin, China. AB - CONTEXT/OBJECTIVE: The objective of the research was to illustrate the epidemiology profile of thoracolumbar fracture (TLF) in Tianjin Medical University General Hospital, China, from 2006-2015. DESIGN: Hospital-based retrospective study. SETTING: Tianjin Medical University General Hospital. METHODS: Medical records of inpatient patients with TLF from 1 January 2006 to December 2015 were collected. Detailed information on epidemiological characters were analyzed based on the medical records suffering from TLF from T11-L2 level, including incidence, age and sex, marital, occupation, etiology and fracture type, types of injuries. RESULTS: Totally 132 cases were identified. The incidence rate was 2.4 patient per million population at 2015. Male-to-female ratio was 1.4:1, with a mean age of 49.1 +/- 17.7 years. The cases number in 46 60 group, totally 35 and accounting for 26.5%, was the largest. There is a significant differences of cases number between 2011-2015 group and 2006-2010 group. Retiree, taken up 48.5%, was the largest group among TLF patients. The most common injury level was T12 (34) accounting for 25.7%. Falls (57, 43.2%) (low falls and high falls) were the leading causes, followed by motor vehicle collisions (MVCs) (23, 17.4%).Compression is the only type of osteoporosis and took up 55.3%. CONCLUSIONS: The incidence ratio is increased annually in TMUGH. Male was more vulnerable than female based on different social character. The average age was older in 2011-2015, retiree accounted for the main proportion and compression took up the largest percentage, the mean age increased and osteoporosis takes more in recent years. PMID- 29595402 TI - Implementing single-item screening for drug use in a Veterans Health Administration outpatient setting. AB - BACKGROUND: Unhealthy drug use is a concern in many settings, including military and veteran populations. In 2013, the Veterans Health Administration (VHA) medical center in Bedford, Massachusetts, started requiring routine screening for unhealthy drug use in outpatient primary care and mental health settings, using a validated single question. METHODS: This study used descriptive and multivariable analyses of VHA electronic records for patients eligible for the screening program (N = 16,118). The study assessed first-year rates and predictors of screening and of positive screens, both for drug use and for unhealthy alcohol use, for which screening was already required. RESULTS: During the first year, 70% of patients were screened for unhealthy drug use and 84% were screened for unhealthy alcohol use. In multivariable analyses, screening for drug use was more likely for patients who had 8 or more days with VHA visits or were aged 40 or over. Patients with a prior drug use disorder diagnosis were much less likely to be screened. Three percent of patients screened for unhealthy drug use had a positive screen, and 14% of those screened for unhealthy alcohol use had a positive screen. Strong predictors of a positive drug use screen included a prior year diagnosis of drug use disorder, any mental health clinic visits, younger age, or being unmarried. CONCLUSIONS: The drug screening initiative was relatively successful in its first-year implementation, having screened 70% of eligible subjects. However, it failed to screen many of those most likely to screen positive, thereby missing many opportunities to address unhealthy drug use. Future refinements should include better training clinicians in how to ask sensitive questions and how to address positive screens. PMID- 29595403 TI - Factors associated with contingency management adoption among opioid treatment providers receiving a comprehensive implementation strategy. AB - BACKGROUND: Contingency management (CM) is an evidence-based behavioral intervention for opioid use disorders (OUDs); however, CM adoption in OUD treatment centers remains low due to barriers at patient, provider, and organizational levels. In a recent trial, OUD treatment providers who received the Science to Service Laboratory (SSL), a multilevel implementation strategy developed by a federally funded addiction training center, had significantly greater odds of CM adoption than providers who received training as usual. This study examined whether CM adoption frequency varied as a function of provider sociodemographic characteristics (i.e., age, race/ethnicity, licensure) and perceived barriers to adoption (i.e., patient-, provider-, organization-level) among providers receiving the SSL in an opioid treatment program. METHODS: Thirty nine providers (67% female, 77% non-Hispanic white, 72% with specialty licensure, Mage = 42 [SD = 11.46]) received the SSL, which consisted of didactic training, performance feedback, specialized training of internal change champions, and external coaching. Providers completed a comprehensive baseline assessment and reported on their adoption of CM biweekly for 52 weeks. RESULTS: Providers reported using CM an average of nine 2-week intervals (SD = 6.35). Hierarchical multiple regression found that providers identifying as younger, non-Hispanic white, and without addiction-related licensure all had higher levels of CM adoption frequency. Higher perceived patient-level barriers predicted lower levels of CM adoption frequency, whereas provider- and organization-level barriers were not significant predictors. CONCLUSIONS: The significant effect of age on CM adoption frequency was consistent with prior research on predictors of evidence-based practice adoption, whereas the effect of licensure was counter to prior research. The finding that CM adoption frequency was lower among racially/ethnically diverse providers was not expected and suggests that the SSL may require adaptation to meet the needs of diverse opioid treatment providers. Entities using the SSL may also wish to incorporate a more explicit focus on patient-level barriers. PMID- 29595404 TI - Association between genetic variants in p53 binding sites and risks of osteosarcoma in a Chinese population: a two-stage case-control study. AB - Osteosarcoma (OS) is one of the most common bone malignancies in children and adolescents. To date, inaugural mechanism of OS was considered as a complex process and was still not clear. The p53 gene, most important tumor suppressors, was associated with risk of many tumors, including OS. In current study, we evaluated the relationship between genetic variation of the p53 binding site and the OS susceptibility through a two-stage case-control study in Chinese population. We found that rs1295925 (OR = 0.85; 95 CI = 0.76-0.94; P = 0.003) and rs3787547 (OR = 1.27; 95 CI = 1.11-1.45; P = 4.0 * 10-4) was significantly with OS susceptibility. Compared with those with rs1295925-TT genotype, and the risk of OS was significantly lower in individuals with CT genotype (OR = 0.77; 95 CI = 0.65-0.92) and CC genotype (OR = 0.75; 95 CI = 0.60-0.93). Compared with those with rs3787547-GG genotype, and the risk of OS was significantly higher in individuals with AG genotype (OR = 1.32; 95 CI = 1.10-1.58) and AA genotype (OR = 1.46; 95 CI = 1.11-1.92). To sum up, our results prove that SNP rs1295925 and rs3787547 play an important role in the etiology of OS, suggesting them as the potential genetic modifier for OS development. PMID- 29595405 TI - Prevalence and Risk Factors of Brucellosis, Chlamydiosis, and Bluetongue Among Sika Deer in Jilin Province in China. AB - Brucellosis and chlamydiosis are important zoonotic diseases and bluetongue virus (BTV) is an arthropod-borne viral disease of ruminants. They are widely distributed around the world, cause large economic losses, and significant harmful effects on humans. However, epidemiological information relating to transmission from commercial sika deer in China is limited. Therefore, from 2016 to 2017, 458 sika deer blood samples were collected from three cities in Jilin Province in China. The Brucella antigen and specific antibodies to Chlamydia and BTV were examined using RT-PCR, indirect hemagglutination assay, and ELISA, respectively. The prevalence of Brucella was found to be 12.9% (59/458) and the seroprevalence of Chlamydia and BTV was 14.4% (66/458) and 17.0% (78/458), respectively. Seasonality was considered a risk factor for the presence of Brucella or BTV in sika deer and the region was considered a risk factor for Chlamydia infection. These data provides reference values for both further research and disease control. PMID- 29595406 TI - Distribution of the Mosquito Communities (Diptera: Culicidae) in Oviposition Traps Introduced into the Atlantic Forest in the State of Rio de Janeiro, Brazil. AB - The Atlantic Rainforest of South America is one of the major biodiversity hotspots of the world and serves as a place of residence for a wide variety of Culicidae species. Mosquito studies in the natural environment are of considerable importance because of their role in transmitting pathogens to both humans and other vertebrates. Community diversity can have significant effects on the risk of their disease transmission. The objective of this study was to understand the distribution of mosquito communities using oviposition traps in a region of the Atlantic Forest. Sampling was carried out in Bom Retiro Private Natural Reserve (RPPNBR), located in Casimiro de Abreu, Rio de Janeiro, using oviposition traps, which were set in the forest environment, from October 2015 to December 2016. The canonical correspondence analysis was used to assess the influence of the climatic variables (precipitation, maximum dew point, and direction) throughout the seasons on the population density of the mosquito species. The results showed that population density was directly influenced by climatic variables, which acted as a limiting factor for the mosquito species studied. The climatic variables that were significantly correlated with the density of the mosquito species were precipitation, maximum dew point, and direction. Haemagogus janthinomys was positively correlated with the three climatic variables, whereas Haemagogus leucocelaenus was positively correlated with precipitation and maximum dew point, and negatively correlated with direction. PMID- 29595407 TI - Chlamydiosis in Backyard Chickens (Gallus gallus) in Italy. AB - Until recently, Chlamydia psittaci was considered to be the only etiological agent of avian chlamydiosis, but two new avian species, Chlamydia gallinacea and Chlamydia avium, have recently been described in poultry and pigeons or psittacine birds, respectively. The aim of this study was to explore the occurrence of C. psittaci and C. gallinacea in backyard chickens in Italy. Cloacal swabs were taken from 160 asymptomatic chickens reared in 16 backyard farms. Samples were tested for C. psittaci and C. gallinacea by specific real time polymerase chain reaction assays, with 24 (15%) of the 160 chickens resulting positive for C. gallinacea. To attempt chlamydial isolation, new samples were obtained from two farms harboring a high prevalence (60% and 70%, respectively) of C. gallinacea-positive chickens. In total, eight C. gallinacea and one C. psittaci isolates were successfully recovered from 13 chickens. C. gallinacea was confirmed to be the endemic chlamydial species in chickens, with a high ompA intraspecies diversity. The presence of viable C. psittaci and C. gallinacea demonstrated by isolation from chickens in backyard farms poses a potential public health problem. PMID- 29595408 TI - An electronic intervention to improve safety for pain patients co-prescribed chronic opioids and benzodiazepines. AB - BACKGROUND: Co-prescribing opioids and benzodiazepines increases overdose risk. A paucity of literature exists evaluating strategies to improve safety of co prescribing. This study evaluated an electronic intervention to improve safety for patients co-prescribed chronic opioids for pain and benzodiazepines at 3 and 6 months. METHODS: A prospective cohort study was conducted from December 2015 through May 2016 at San Francisco Veterans Affairs Health Care System. A clinical dashboard identified 145 eligible patients prescribed chronic opioids and benzodiazepines. Individualized taper and safety recommendations were communicated to prescribers via electronic medical record progress note and encrypted e-mail at baseline. Primary outcome was number of patients co prescribed chronic opioids and benzodiazepines. Secondary outcomes included daily dose of opioids and benzodiazepines and number prescribed >=100 mg morphine equivalent daily dose. Safety outcomes included number with opioid overdose education and naloxone distribution, annual urine drug screening, annual prescription drug monitoring program review, and signed opioid informed consent. Linear mixed models and generalized estimating equations were used to examine within-group change in outcomes between baseline and 3 and 6 months. RESULTS: Among the 145 patients, mean (standard deviation) age was 62 (11) years and 91.7% (133/145) were male. Number co-prescribed significantly decreased from 145/145 (100%) at baseline to 93/139 (67%) at 6-month follow-up (odds ratio [OR] = 0.53, 95% confidence interval [CI]: 0.34-0.81, P = .003). Mean opioid and benzodiazepine doses significantly decreased from 84.61 to 65.63 mg (95% CI: 8.32 27.86, P < .001) and from 16.10 to 13.45 mg (95% CI: 1.6-3.9, P < .001), respectively, from baseline to 6-month follow-up. Patients prescribed >=100 mg morphine equivalent daily dose significantly decreased from 39/145 (26.8%) at baseline to 26/139 (18.7%) at end of study (OR = 0.59, 95% CI: 0.44-0.78, P < .001), and patients with opioid overdose education and naloxone distribution significantly increased from 3/145 (2.1%) at baseline to 46/139 (33.1%; OR = 23.4, 95% CI: 7.61-71.99, P < .001) by the end of study. Number of patients with annual urine drug screening tended to increase from 123/145 (84.8%) at baseline to 132/145 (91.4%) by the end of study (OR = 1.89, 95% CI: 0.95-3.76, P = .07), and there were no significant changes across time in numbers of patients with annual prescription drug monitoring program review or signed opioid informed consent. CONCLUSIONS: Electronic interventions may provide an effective strategy to improve safety for patients co-prescribed chronic opioids for pain and benzodiazepines.

AB - A landfill is one of the main sites for disposal of municipal solid waste and the current landfill disposal system faces several problems. For instance, excessive leachate water is an important factor leading to landfill instability. Understanding the permeability characteristics of municipal solid waste is a relevant topic in the field of environmental geotechnical engineering. In this paper, the current research progress on permeability characteristics of municipal solid waste is discussed. A review of recent studies indicates that the research in this field is divided into two categories based on the experimental method employed: field tests and laboratory tests. This paper summarizes test methods, landfill locations, waste ages, dry densities and permeability coefficients across different studies that focus on permeability characteristics. Additionally, an experimental study on compressibility and permeability characteristics of fresh municipal solid waste under different effective stresses and compression times was carried out. Moreover, the relationships between the permeability coefficient and effective stress as well as dry density were obtained and a permeability prediction model was established. Finally, the experimental results from the existing literature and this paper were compared and the effects of effective stress and dry density on the permeability characteristics of municipal solid waste were summarized. This study provides the basis for analysis of leachate production in a landfill. PMID- 29595410 TI - A novel approach to treating adolescents with opioid use disorder in pediatric primary care. AB - BACKGROUND: Medication treatment for opioid use disorder is effective, and is recommended for adolescents, although very few adolescents with opioid use disorder ever receive medications. Reasons include lack of trained medication prescribers for this age group and difficulty in identifying adolescents with substance use disorders. This paper examines a novel implementation model of identifying and providing treatment for substance use disorders, including opioid use disorder, in a pediatric primary care practice. METHODS: Patients presenting to a selected primary care pediatrics practice for any reason between March 9, 2017, and July 24, 2017, who were identified by screening, self-report, or other clinical information to have a substance use problem were referred to an integrated clinical social worker for treatment. The authors recorded the number of patients who were referred, number of visits completed, and substance use disorder and mental health diagnoses. RESULTS: In the first 4 months of this program, 683 patients aged 12-22 completed a health maintenance appointment; 20 were referred for substance use disorder treatment and 13 completed at least 1 substance use disorder treatment visit with the integrated clinical social worker. The mean number of visits completed was 5.3. Three patients with opioid use disorders were identified, and 2 were induced on buprenorphine. CONCLUSIONS: The current model for treatment of substance use disorders, including opioid use disorders, was feasible and acceptable in a pediatric primary care practice. Broadly implemented, such a model could substantially increase access to substance use disorder treatment for adolescents and young adults. PMID- 29595411 TI - Comparison of relative and absolute values of magnetic resonance imaging in the diagnosis of spinal epidural lipomatosis. AB - Objective To describe spinal epidural lipomatosis (SEL) of the lumbar region and evaluate the relative versus absolute values of epidural fat (EF) to determine which is more appropriate when using magnetic resonance imaging (MRI). Design Comparative study. Setting Hospital. Participants Eight SEL patients and 40 healthy adults. Interventions MRI measurement of EF. Outcome Measures The MRI based EF thickness, cutoff value, and coefficient of variation (CV) were calculated. Frequency distribution maps for the absolute EF value and the relative EF/DuS value were created. Results SEL involved L3 - L4 in all cases. The mean EF thickness was 12.11 +/- 2.28 mm (range: 9.91 - 16.86 mm), and the average diameter of the dural sac (DuS) was 20.02 +/- 2.64 mm; the EF/DuS ratio was 0.61 +/- 0.03. In controls, the average EF thickness was 7.35 +/- 1.68 mm (range: 4.81 - 10.92 mm), and the average DuS was 20.86 +/- 2.11 mm; the EF/DuS ratio was 0.35 +/- 0.08. The relative and absolute values were significantly higher in the SEL group than in the normal group. A cutoff value of 9.8 mm could distinguish SEL patients from normal individuals. For the SEL group, the CV of the relative values (4.9%) was lower than that of the absolute values (18.8%). The frequency distribution map showed that the distribution of relative values was more concentrated than that of the absolute values for both groups. Conclusion Based on the frequency distribution and CVs, the relative value of EF/DuS maybe a better measure for diagnosing SEL than the absolute EF value.

AB - Shigella are ranked among the most prevalent aetiologies of diarrhoeal disease worldwide, disproportionately affecting young children in developing countries and high-risk communities in developed settings. Antimicrobial treatment, most commonly with fluoroquinolones, is currently recommended for Shigella infections to alleviate symptoms and control disease transmission. Resistance to fluoroquinolones has emerged in differing Shigella species (S. dysenteriae, flexneri and sonnei) since the turn of the 21st century, originating in endemic areas, and latterly spreading into non-endemic regions. Despite occurring independently, the emergence of fluoroquinolone resistance in these different Shigella species shares striking similarities regarding their epidemiology and resistance mechanisms. Here, we review and discuss the current epidemiology of fluoroquinolone-resistant Shigella species, particularly in the light of recent genomic insights. PMID- 29595413 TI - Pseudomonas furukawaii sp. nov., a polychlorinated biphenyl-degrading bacterium isolated from biphenyl-contaminated soil in Japan. AB - Strain KF707T was isolated from a biphenyl-contaminated site in Kitakyushu, Japan. Analysis of 16S rRNA gene sequences, retrieved from the whole-genome sequence, revealed that the isolate was closely related to members of the genus Pseudomonas, sharing the highest sequence similarities with Pseudomonas balearica strain SP1402T (DSM 6083) (97.8 %). The DNA G+C chromosome and plasmid content of strain KF707T were 65.5 and 60.5 mol%. The major cellular fatty acids were iso C15 : 0 and C16 : 1omega7c/C16 : 1omega6c. Polyphasic analysis indicated that strain KF707T represents a novel species of the genus Pseudomonas, for which the name Pseudomonas furukawaii sp. nov. is proposed. The type strain is KF707T (=DSM 10086T=NBRC 110670T). PMID- 29595414 TI - The FlaG regulator is involved in length control of the polar flagella of Campylobacter jejuni. AB - Campylobacter jejuni cells have bipolar flagella. Both flagella have similar lengths of about one helical turn, or 3.53+/-0.52 um. The flagellar filament is composed of two homologous flagellins: FlaA and FlaB. Mutant strains that express either FlaA or FlaB alone produce filaments that are shorter than those of the wild-type. It is reported that the flaG gene could affect filament length in some species of bacteria, but its function remains unknown. We introduced a flaG deletion mutation into the C. jejuni wild-type strain and flaA- or flaB-deletion mutant strains, and observed their flagella by microscopy. The DeltaflaG mutant cells produced long filaments of two helical turns in the wild-type background. The DeltaflaAG double mutant cells produced very short FlaB filaments. On the other hand, DeltaflaBG double mutant cells produced long FlaA filaments and their morphology was not helical but straight. Furthermore, FlaG was secreted, and a pulldown assay showed that sigma factor 28 was co-precipitated with purified polyhistidine-tagged FlaG. We conclude that FlaG controls flagella length by negatively regulating FlaA filament assembly and discuss the role of FlaA and FlaB flagellins in C. jejuni flagella formation. PMID- 29595416 TI - Proposal for a new classification of a deep branching bacterial phylogenetic lineage: transfer of Coprothermobacter proteolyticus and Coprothermobacter platensis to Coprothermobacteraceae fam. nov., within Coprothermobacterales ord. nov., Coprothermobacteria classis nov. and Coprothermobacterota phyl. nov. and emended description of the family Thermodesulfobiaceae. AB - The genus Coprothermobacter (initially named Thermobacteroides) is currently placed within the phylum Firmicutes. Early 16S rRNA gene based phylogenetic studies pointed out the great differences between Coprothermobacter and other members of the Firmicutes, revealing that it constitutes a new deep branching lineage. Over the years, several studies based on 16S rRNA gene and whole genome sequences have indicated that Coprothermobacter is very distant phylogenetically to all other bacteria, supporting its placement in a distinct deeply rooted novel phylum. In view of this, we propose its allocation to the new family Coprothermobacteraceae within the novel order Coprothermobacterales, the new class Coprothermobacteria, and the new phylum Coprothermobacterota, and an emended description of the family Thermodesulfobiaceae. PMID- 29595417 TI - Genotypic characterization of Haemophilus influenzae isolates from paediatric patients in Japan. AB - PURPOSE: beta-lactamase-negative ampicillin-resistant (BLNAR) Haemophilus influenzae is frequently isolated from respiratory samples and is particularly problematic in Japan. The aim of this study was to characterize circulating isolates of H. influenzae genotypically by BLNAR-PCR and multilocus sequence typing (MLST), and to determine any associations between them. METHODS: H. influenzae isolates (n=191) were collected from paediatric patients (1 month to 12 years old) between 2000 and 2011 for three types of infections: pneumonia (n=61), acute otitis media (AOM) (n=68) and meningitis (n=62). All were characterized for capsular type by agglutination tests, and for beta-lactam resistance by real-time PCR. The sequence types (STs) determined by MLST were analysed using eburst v3. RESULTS: Eighty-eight out of 191 (46.1 %) H. influenzae isolates were BLNAR by PCR; 37 of 61 (60.7 %) from pneumonia; 33 of 68 (48.5 %) from AOM and 18 of 62 (29.0 %) from meningitis cases. MLST identified 40 and 44 STs among isolates from pneumonia and AOM, respectively. BLNAR were found in singletons such as ST156 in pneumonia, and ST161 and ST396 in AOM. In contrast, eight STs were identified in meningitis, of which seven were genotypically closely related, while ST54 was the most frequent (62.9 %), unlike in the MLST database registrations, where ST6 predominated. CONCLUSION: Non-typeable H. influenzae (NTHi), mostly derived from pneumonia and AOM, were genetically diverse, in contrast to the predominance of H. influenzae type b (Hib) among meningitis cases. The associations between certain STs and beta-lactam resistance among NTHi were confirmed. PMID- 29595415 TI - High-throughput sequencing identification and characterization of potentially adhesion-related small RNAs in Streptococcus mutans. AB - PURPOSE: Adherence capacity is one of the principal virulence factors of Streptococcus mutans, and adhesion virulence factors are controlled by small RNAs (sRNAs) at the post-transcriptional level in various bacteria. Here, we aimed to identify and decipher putative adhesion-related sRNAs in clinical strains of S. mutans. METHODOLOGY: RNA deep-sequencing was performed to identify potential sRNAs under different adhesion conditions. The expression of sRNAs was analysed by quantitative real-time PCR (qRT-PCR), and bioinformatic methods were used to predict the functional characteristics of sRNAs. RESULTS: A total of 736 differentially expressed candidate sRNAs were predicted, and these included 352 sRNAs located on the antisense to mRNA (AM) and 384 sRNAs in intergenic regions (IGRs). The top 7 differentially expressed sRNAs were successfully validated by qRT-PCR in UA159, and 2 of these were further confirmed in 100 clinical isolates. Moreover, the sequences of two sRNAs were conserved in other Streptococcus species, indicating a conserved role in such closely related species. A good correlation between the expression of sRNAs and the adhesion of 100 clinical strains was observed, which, combined with GO and KEGG, provides a perspective for the comprehension of sRNA function annotation. CONCLUSION: This study revealed a multitude of novel putative adhesion-related sRNAs in S. mutans and contributed to a better understanding of information concerning the transcriptional regulation of adhesion in S. mutans. PMID- 29595418 TI - Human papillomavirus (HPV) 16 E6 oncoprotein targets the Toll-like receptor pathway. AB - Cervical cancer is one of the leading causes of death in women worldwide and is etiologically linked to human papillomavirus (HPV) infection. Viral early proteins E6 and E7 manipulate cellular functions to promote the virus life cycle and are essential to the cellular transformation process. The innate immune system plays a pivotal role in the natural history of HPV infection. Among the various proteins that mediate the innate immune response, Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns (PAMPs) and initiate the immune response. The objective of this study was to identify HPV E6 protein interaction partners in the TLR signalling pathway that may play a role in the immune response against HPV. Six TLR pathway proteins were shown to interact with HPV16 E6: myeloid differentiation primary response protein (MyD88), TIR domain containing adapter molecule 1 (TRIF), interleukin-1 receptor-associated kinase like (IRAK) 2, TNF receptor-associated factor (TRAF) 6, I-kappaB kinase beta (IKKbeta) and I-kappaB kinase epsilon (IKKepsilon). The interaction site of IKKepsilon with E6 is located in the region containing the enzyme catalytic site, suggesting an influence of E6 on the activation of IKKepsilon target proteins. HPV16 E6 potentiated the activation of NF-kappaB by various TLR pathway members. These results suggest that HPV16 has the ability to interfere with components of the immune response, contributing to HPV carcinogenesis. PMID- 29595419 TI - From the Editors.

AB - Indigenous data governance principles assert that Indigenous communities have a right to data that identifies their people or communities, and a right to determine the use of that data in ways that support Indigenous health and self determination. Indigenous-driven use of the databases held at the Institute for Clinical Evaluative Sciences (ICES) has resulted in ongoing partnerships between ICES and diverse Indigenous organizations and communities. To respond to this emerging and complex landscape, ICES has established a team whose goal is to support the infrastructure for responding to community-initiated research priorities. ICES works closely with Indigenous partners to develop unique data governance agreements and supports processes, which ensure that ICES scientists must work with Indigenous organizations when conducting research that involves Indigenous peoples. PMID- 29595421 TI - Opioid-Related Harms in Canada. AB - The rise in harms associated with opioids is an issue of increasing public health importance in Canada. The Government of Canada recently reported 2,816 apparent opioid-related deaths across the country in 2016. Recent 2017 data show that deaths involving fentanyl-related opioids have doubled from January to March as compared to the same time period in 2016 (Government of Canada 2017). Additional measures that provide a better understanding of opioid-related harms, such as hospitalizations and emergency department (ED) visits, are a high priority. The objective of this study is to present pan-Canadian data on hospitalizations and ED visits because of opioid poisoning.

AB - Cancer patients experience a high symptom burden throughout their illness. Quality cancer symptom management has been shown to improve patient quality of life and prevent emergency department use. Cancer Care Ontario introduced standardized symptom screening in Ontario, using the Edmonton Symptom Assessment System (ESAS) to facilitate patient reporting and management of symptoms. However, patient symptom information is not always sufficiently addressed. To address these gaps, patient and family advisors collaborated with clinicians, administrators and health system leaders from across the Province in a Symptom Management Summit to share perspectives and co-design context-specific solutions to improve care in their region. PMID- 29595424 TI - Success Strategies for Linguistically Competent Healthcare: The Magic Bullets and Cautionary Tales of the Active Offer of French-Language Health Services in Ontario. AB - An active offer of French-language health services (FLHS) was introduced in several Canadian provinces to help create an environment that will anticipate the needs of Francophones in their community and will stimulate the demand for services in French. For the active offer to be implemented, changes in how health services are organized and managed at both organizational and system levels must be introduced. In this perspective paper, we identify several success strategies and potential pitfalls with regards to the implementation of the active offer of FLHS primarily at the level of healthcare organization. Our recommendations are based on a recent health services research study exploring reorganization and management strategies for the delivery of the active offer of FLHS in Ontario and insights from a focus group with healthcare administrators conducted as part of this research. We propose a ";wrap-around strategy" called organizational health literacy to help reorient organizational culture and improve management and sustainability of the active offer of FLHS. These strategies have relevance for advocates and professionals working to promote an active offer of FLHS, including healthcare administrators, human resource professionals, quality-improvement specialists and others.

AB - The expression "shame and blame" has often been used to describe the culture within healthcare when a mistake is made. There has been little exploration, however, on the shame healthcare professionals experience after a mistake. Based on an original grounded theory study on the psychological impact of mistakes on health professionals, this article explores why the healthcare environment is a perfect ecosystem for growing shame, how individuals are coping or not coping with the negative effects of this powerful emotion and what might be done at the system, organizational and team level to mitigate these negative effects.

AB - Poor hospital unit culture and staff morale, and dysfunctional multidisciplinary cooperation leads to worse patient safety and satisfaction. The Walk in My Shoes research project aimed to understand how interprofessional job shadowing impacts the attitudes of colleagues. Thirty-three registered nurses at an acute care hospital observed the daily work of social workers. Nurses' attitudes towards social workers were measured by surveys and interviews. Quantitative data indicated a change in nurses' perception of social workers' communication, teamwork and autonomy. Qualitative data indicate that job shadowing helped participants identify personal misperceptions, provided new understanding of roles and gave insight into co-worker job similarities. PMID- 29595427 TI - Bundling Care for Cardiac Surgery Patients. AB - Patients returning to the community after surgery often experience a disconnect when transitioning from hospital to community home care. Many receive little organized/planned care following discharge sometimes resulting in unplanned expensive care in hospital emergency departments and inpatient readmissions. Trillium Health Partners, a large community/teaching hospital, in partnership with community care provider Saint Elizabeth Health Care, designed and implemented a seamless "bundled care program" for cardiac surgery patients extending from hospitalization to 30 days after discharge. With a risk/gain sharing model, the bundled care program enabled a novel integrated clinical patient care model. This included integrated care coordinators embedded within the hospital team, 24/7 patient phone line, integrated medical records and a tracking board that enabled performance monitoring and improvement. Evaluation results revealed: a 16% reduction in post-operative length of stay; a 38% reduction in readmission rates; and a 13% decrease in total system cost per patient, together with markers of improved patient experience.

AB - Ottawa has a 31-bed palliative care unit (PCU) and two residential adult hospices (total 19 beds). In 2013, we initiated a project to improve the referral and triage processes to these beds. Previously, there were two separate paper-based systems with duplication, inefficiencies, delays and inappropriate patient placements. The multipronged approach included clarifying the respective roles of the PCU and hospices, creating a single referral and triage office and developing an e-platform. We leveraged technology that was available in the public-funded system. This paper describes the development processes, lessons learned, and the final system, referred to as System to Manage Access, Referrals and Triage (SMART).

PMID- 29595435 TI - Medicare Cost Drivers during the 2004-2014 Health Accord Period in Canada: What Is the Evidence? AB - As per the Canada Health Act, hospital and physician services (Medicare) are covered by the public sector. With the 2004 First Minister's Health Accord showcasing a 10-Year Plan to strengthen healthcare in Canada, significant investments have been made to improve access to these services. The average annual growth rate (AAGR) of spending between 2004 and 2014 was 5.1% for hospitals and 6.6% for physicians. The key policy question is whether or not these increases were just used to boost unit cost? An accounting approach was used to address this issue. Results suggest that for hospitals, wage per hour for staff (excluding physicians) accounted for 49% of the AAGR for hospitals (2.5 percentage points [pp]), while fee increases accounted for 47% of the AAGR for physician spending (3.1 pp). However, considering that general inflation was on average 1.8% per year, the health premium for physicians represented almost twice that for hospital staff.

AB - New health technologies enter Canadian healthcare organizations in various ways, and understanding them is essential to the development of a pan-Canadian Health Technology Management (HTM) Strategy, now a priority of governments across Canada. One way is through Health Canada's Medical Devices Special Access Program (MDSAP), which permits unlicensed devices to be obtained by healthcare professionals. However, the circumstances around and implications of the current use of this program are not clear. A scoping literature review was conducted to clarify these and identify important roles and issues related to the MDSAP. Limited information was found on the MDSAP. Nevertheless, three themes demonstrating the roles of the MDSAP in HTM emerged: arbiter in technology selection, a route to technology procurement and facilitator of health technology innovation. No information suggesting that MDSAP is used to circumvent licensing was found. Rather, it enables desired patient outcomes and product commercialization. PMID- 29595437 TI - Understanding Patient Referral Wait Times for Specialty Care in Ontario: A Retrospective Chart Audit. AB - CONTEXT: When examining wait times for specialist care, the duration between a patient's referral and specialist visit (wait time one) is poorly understood. OBJECTIVES: To calculate wait time one in primary care clinics across Ontario using chart audit. METHODS: We conducted a retrospective chart audit at five Ontario-based primary care clinics in 2014-2015. RESULTS: We analyzed 461 referrals. Median wait time one for non-urgent and urgent referrals was 79 and 49 days, respectively. Gastroenterology, obstetrics/gynecology, and ear, nose and throat received the most referrals. Wait times were longest for dermatology (112 days) and shortest for general surgery (32 days). CONCLUSION: Wait times vary substantially by referral urgency and specialty type in Ontario. Calculating wait time from primary care clinics directly offers new perspectives on wait time one and enables clinics to target improvement efforts to best meet patient needs. Our findings will be relevant to providers and policy makers interested in implementing strategies to reduce wait times. PMID- 29595438 TI - Shaping the Future of Patient Experience Measurement in Canadian Healthcare. AB - Patients' experiences with healthcare providers can be tumultuous and stressful. Focusing on what matters, the experience of care is important to improving patients' quality of life. In this issue's lead article, Kuluski and colleagues (2017) propose moving beyond setting-based patient experience measures. In doing so, the authors emphasize the importance of caregivers and the communities in which patients live in improving patients' and caregivers' care experiences. To achieve these aims, however, the authors demand a higher level of reflexivity from provinces' healthcare funders and providers. PMID- 29595439 TI - Experience of Care as a Critical Component of Health System Performance Measurement: Recommendations for Moving Forward. AB - People's experiences can provide critical guidance on how to better meet their quality of life and care needs and deploy resources more appropriately. To maximize the utility of experience data and to advance the current debate, we present four recommendations: (1) measuring experiences outside the healthcare system can provide insight into what needs to change within the healthcare system; (2) focusing on patient experience is necessary but insufficient, (family) caregiver insights and experiences require attention and can provide insight into the needs of the patient; (3) moving from "one time/single sector" measurement of experience to iterative, ongoing measurement across sectors better reflects the true lived experience of patients (especially those with complex care needs) and their caregivers; and (4) embedding measurement within engagement capable environments that adequately resource patients, caregivers, and providers to work together is required to move from collection to meaningful change. Applying these recommendations requires a longer-term vision, shifting from provider-centred to person-centred models of care, and a deep understanding of the structural, cultural, and normative barriers to measuring care experiences. PMID- 29595440 TI - Measuring Patient Experiences: Is It Meaningful and Actionable? AB - Performance measurement must be meaningful to those being asked to contribute data and to the clinicians who are collecting the information. It must be actionable if performance measurement and reporting is to influence health system transformation. To date, measuring patient experiences in all parts of the healthcare system in Canada lags behind other countries. More attention needs to be paid to capturing patients with complex intersecting health and social problems that result from inequitable distribution of wealth and/or underlying structural inequities related to systemic issues such as racism and discrimination, colonialism and patriarchy. Efforts to better capture the experiences of patients who do not regularly access care and who speak English or French as a second language are also needed. Before investing heavily into collecting patient experience data as part of a performance measurement system the following ought to be considered: (1) ensuring value for and buy-in from clinicians who are being asked to collect the data and/or act on the results; (2) investment in the infrastructure to administer iterative, cost-effective patient/family experience data collection, analysis and reporting (e.g., automated software tools) and (3) incorporating practice support (e.g., facilitation) and health system opportunities to integrate the findings from patient experience surveys into policy and practice. Investment into the infrastructure of measuring, reporting and engaging clinicians in improving practice is needed for patient/caregiver experiences to be acted upon. PMID- 29595441 TI - Health System Performance Measurement: A UK Perspective. AB - In response to the lead article by Kuluski et al. (2017), this commentary draws on UK debates around the quality of healthcare and on the author's personal experience training as a social worker. Judging whether a service has "worked" has to involve understanding what a good outcome would be for the person receiving it. While carers provide important insights here, the "user" may have a different view, and reconciling different perspectives can be challenging. Although individual services may have fulfilled their part of the process, it is important to look at the person's overall experience (although this is difficult to achieve in practice). There is also no point measuring patient experience if we are not prepared to really listen to the feedback we receive. Moving forward, the UK's personalization agenda - which focuses on giving people greater choice and control - may enhance the aims of Kuluski et al.'s work. PMID- 29595442 TI - Reacting to Patient Experience Results - How Can We Be Proactive? AB - Among the recommendations raised in the lead paper (Kuluski et al. 2017) for optimizing the utility of patient experience data are several important questions about the nature of person-centred care, the engagement of patients and caregivers in evaluating care and the need to address barriers to measurement. This commentary focuses on the concept that common approaches to measuring patient experience are reactive by design. To truly enhance our patients' experience, we must first connect with patients to understand what they want from their care experience. In addition, this paper explores the practicality of using patient experience data for quality improvement, particularly if there is a shift towards measuring experience across the system of care. PMID- 29595443 TI - Engagement-Capable Environments - No Less Challenging than other Large System Changes. AB - Kuluski et al.'s (2017) argument for including a more advanced form of health system performance management centred on "the experience of care," raises the major challenge of creating and sustaining engagement-capable environments. Here I briefly address frameworks that may be useful in meeting this challenge - Complex Adaptive Systems, Innovation Diffusion, Whole System Change. I also offer a personal perspective drawn from a successful citizen engagement experience, concluding with a perspective on the numerous challenges we have or are in the process of overcoming compared to the challenges of engagement-capable environments. PMID- 29595444 TI - More than just Measurement. AB - I have reviewed with pleasure the article by Kuluski et al. (2017) who posit that measures of patient experience are required to more effectively guide healthcare reform. While I am generally in support of the original paper, I argue in this commentary that: (1) measuring patient engagement experience should not be done in isolation from broader change management processes; (2) care must be taken to ensure that measures of patient experience are developed with rigor and do not further complicate the already vast performance metrics literature and, (3) any revised set of performance metrics requires ongoing evaluation, to help ensure its optimal value. PMID- 29595445 TI - Experience of Care - Furthering the Patient Experience Agenda. AB - The measurement of the patient experience is a global movement that has caught the attention of healthcare reformers. The use of patient experience data to ameliorate healthcare practice is promising, although standardization in what, where, how and whose experience is measured does not yet exist. To truly further the patient experience agenda, there needs to be adoption at the system, regional and local level to help promote, inspire and lead to sustainable change. Caregiver insight into the patient experience should be leveraged to learn what is important to patients and extract more useful data, as they are often present during transitions in care that span across the continuum. Embracing the voice of the patient as part of the process to improve quality, outcomes and experience will no doubt lead to impactful change and better care. PMID- 29595446 TI - Rethinking Healthcare Performance Evaluation Systems towards the People Centredness Approach: Their Pathways, their Experience, their Evaluation. AB - Patient experience should be the starting point to achieve a high quality of care. Coherently, healthcare performance evaluation systems, driving the change in line with the main strategic goals, should be designed considering the patient perspective. Instead, they are traditionally defined according to the healthcare service provider's point of view. Consequently, they reproduce a "silo-vision" characterized by a clear separation of responsibilities limited to a specific setting of care or to a single organization. This commentary discusses the importance of using patient-reported measures together with indicators based on administrative data to evaluate cross-setting healthcare services within a multidimensional healthcare performance evaluation system. The experience of the Tuscany regional healthcare Performance Measurement System (PMS), implemented more than 10 years ago and in continuous evolution, represents an innovative example of how to measure the quality of the whole care pathway including patient experience. This new approach is based on a systematic, systemic and standardized collection of patient-reported experience measures in several healthcare pathways and evaluating them using a coherent graphical representation. Targets, incentives and other managerial tools are fixed, overcoming organizational boundaries and integrating the patient point of view with the goal of moving the healthcare system towards a patient-centredness approach to care. PMID- 29595447 TI - Putting Performance Measurement Recommendations into Practice: Building on Current Practices. AB - Improving performance measurement within the Canadian healthcare system is proving to be challenging despite advances in evidence-informed care and best practices for healthcare delivery. Perhaps what is most challenging is the need to meet requirements to measure what most Canadians hold dear - being seen as a person during a healthcare encounter. Measures of healthcare delivery have typically been developed to capture patient satisfaction during isolated healthcare encounters. Such measures simply do not get to the essence of what matters to patients and their families. This paper outlines a response to the paper by Kuluski and colleagues (2017) that calls for a thorough review of the way data are currently captured on patients' experiences with healthcare. Using geriatric medicine as a context, the authors highlight elements of our current care delivery models that must be preserved, modified or created to allow patients and families to play a larger role in improving our healthcare system. PMID- 29595448 TI - From Volumes to Valued Experiences: Measurement and the Challenge before Us. AB - We are grateful for the thoughtful discussion and ideas put forth in this issue on the measurement of healthcare experiences. Our colleagues, who span multiple jurisdictions across Canada and internationally, agree that we need to do a better job at engaging patients and families in their care and measuring their experiences across health services and sectors. In this response paper, we reflect on three core content areas that were identified across the eight papers in this issue: the role of context and engagement-capable environments; approaches to improve the measurement of experience and acting on results; and challenges that must be attended to in our quest to make our healthcare systems work better. PMID- 29595449 TI - Routine low-dose continuous or nocturnal oxygen for people with acute stroke: three-arm Stroke Oxygen Supplementation RCT. AB - BACKGROUND: Stroke is a major cause of death and disability worldwide. Hypoxia is common after stroke and is associated with worse outcomes. Oxygen supplementation could prevent hypoxia and secondary brain damage. OBJECTIVES: (1) To assess whether or not routine low-dose oxygen supplementation in patients with acute stroke improves outcome compared with no oxygen; and (2) to assess whether or not oxygen given at night only, when oxygen saturation is most likely to be low, is more effective than continuous supplementation. DESIGN: Multicentre, prospective, randomised, open, blinded-end point trial. SETTING: Secondary care hospitals with acute stroke wards. PARTICIPANTS: Adult stroke patients within 24 hours of hospital admission and 48 hours of stroke onset, without definite indications for or contraindications to oxygen or a life-threatening condition other than stroke. INTERVENTIONS: Allocated by web-based minimised randomisation to: (1) continuous oxygen: oxygen via nasal cannula continuously (day and night) for 72 hours after randomisation at a flow rate of 3 l/minute if baseline oxygen saturation was <= 93% or 2 l/minute if > 93%; (2) nocturnal oxygen: oxygen via nasal cannula overnight (21:00-07:00) for three consecutive nights. The flow rate was the same as the continuous oxygen group; and (3) control: no routine oxygen supplementation unless required for reasons other than stroke. MAIN OUTCOME MEASURES: Primary outcome: disability assessed by the modified Rankin Scale (mRS) at 3 months by postal questionnaire (participant aware, assessor blinded). Secondary outcomes at 7 days: neurological improvement, National Institutes of Health Stroke Scale (NIHSS), mortality, and the highest and lowest oxygen saturations within the first 72 hours. Secondary outcomes at 3, 6, and 12 months: mortality, independence, current living arrangements, Barthel Index, quality of life (European Quality of Life-5 Dimensions, three levels) and Nottingham Extended Activities of Daily Living scale by postal questionnaire. RESULTS: In total, 8003 patients were recruited between 24 April 2008 and 17 June 2013 from 136 hospitals in the UK [continuous, n = 2668; nocturnal, n = 2667; control, n = 2668; mean age 72 years (standard deviation 13 years); 4398 (55%) males]. All prognostic factors and baseline characteristics were well matched across the groups. Eighty-two per cent had ischaemic strokes. At baseline the median Glasgow Coma Scale score was 15 (interquartile range 15-15) and the mean and median NIHSS scores were 7 and 5 (range 0-34), respectively. The mean oxygen saturation at randomisation was 96.6% in the continuous and nocturnal oxygen groups and 96.7% in the control group. Primary outcome: oxygen supplementation did not reduce disability in either the continuous or the nocturnal oxygen groups. The unadjusted odds ratio for a better outcome (lower mRS) was 0.97 [95% confidence interval (CI) 0.89 to 1.05; p = 0.5] for the combined oxygen groups (both continuous and nocturnal together) (n = 5152) versus the control (n = 2567) and 1.03 (95% CI 0.93 to 1.13; p = 0.6) for continuous versus nocturnal oxygen. Secondary outcomes: oxygen supplementation significantly increased oxygen saturation, but did not affect any of the other secondary outcomes. LIMITATIONS: Severely hypoxic patients were not included. CONCLUSIONS: Routine low-dose oxygen supplementation in stroke patients who are not severely hypoxic is safe, but does not improve outcome after stroke. FUTURE WORK: To investigate the causes of hypoxia and develop methods of prevention.

PMID- 29595450 TI - [Analysis of the correlation between E2F3 expression and the number of tumor infiltrating CD8+T cells in invasive bladder cancer tissues]. AB - Objective To investigate the expression of E2F transcription factor 3 (E2F3) and the infiltration of CD8+T cells in bladder cancer tissues and their correlations with the malignant biological behaviors of bladder cancer. Methods The expression level of E2F3 and the infiltration characteristics of CD8+T cells in 110 cases of bladder cancer tissues with different histological stage and grade as well as in the corresponding normal bladder tissues were detected by immunohistochemistry. Western blot analysis was used to detect E2F3 and CD8 protein levels in 82 cases of bladder cancer tissues and the corresponding normal bladder tissues, and then the correlation between E2F3 expression and CD8+ T cell infiltration was analyzed statistically by linear correlation analysis. Results The expression of E2F3 was higher in the bladder cancer tissues than in the normal bladder tissues. The expression level of E2F3 increased gradually with the increase of tumor histological stage and grade, while the number of tumor-infiltrating CD8+T cells decreased gradually in the corresponding tumors, and the number of tumor infiltrating CD8+T cells in E2F3 high expression group was significantly lower than that in E2F3 low expression group. Both the rate of E2F3 positive expression and the decrease in the number of tumor-infiltrating CD8+T cells were closely related to tumor clinical invasive indicators, such as tumor histological stage, grade, tumor size, lymph node metastasis or distant metastasis. Linear correlation analysis indicated that the number of tumor-infiltrating CD8+T cells was negatively correlated with the expression of E2F3. Survival analysis revealed that the prognosis of patients with high E2F3 expression was worse after operation within 5 years. Conclusion The expression level of E2F3 in bladder cancer is closely related to tumor invasiveness, and is negatively correlated with the number of tumor-infiltrating CD8+T cells. PMID- 29595452 TI - [Overexpression of miR-519d-3p inhibits the proliferation of DU-145 prostate cancer cells by reducing TRAF4]. AB - Objective To observe the effect of microRNA-519d-3p (miR-519d-3p) on the proliferation of prostate cancer cells and explore the possible molecular mechanism. Methods The expression level of miR-519d-3p in PC-3, DU-145, 22RV1, PC 3M, LNCaP human prostate cancer cells and RWPE-1 human normal prostate epithelial cells was detected by real-time quantitative PCR. miR-519d-3p mimics or negative control microRNAs (miR-NC) was transfected into the prostate cancer cells with the lowest level of miR-519d-3p expression. Transfection efficiency was examined. The effect of miR-519d-3p on the cell cycle of prostate cancer was detected by flow cytometry. MTT assay and plate clone formation assay were used to detect its effect on the proliferation of prostate cancer cells. Bioinformatics software was used to predict and dual luciferase reporter assay was used to validate the target gene of miR-519d-3p. Real-time quantitative PCR was used to detect the expression of miR-519d-3p target gene. Western blot analysis was used to detect the expression of target gene protein and downstream protein. Results The expression of miR-519d-3p in normal prostate epithelial cells was significantly higher than that in prostate cancer cells, and the lowest was found in DU-145 cells. After transfected with miR-519d-3p mimics, the expression level of miR 519d-3p in DU-145 cells increased significantly. Bioinformatics prediction and dual luciferase reporter gene confirmed that tumor necrosis factor receptor associated factor 4 (TRAF4) was the target gene of miR-519d-3p. Overexpression of miR-519d-3p significantly reduced the expression of TRAF4 gene and its downstream TGF-beta signaling pathway proteins in the prostate cancer cells. Conclusion The expression of miR-519d-3p is down-regulated in prostate cancer cells. Overexpression of miR-519d-3p can inhibit the proliferation of prostate cancer cells. The possible mechanism is that miR-519d-3p inhibits the expression of TRAF4. PMID- 29595451 TI - [LRIG1 promotes the apoptosis of pituitary tumor cells induced by cisplatin]. AB - Objective To investigate the expression of leucine rich repeats and immunoglobulin like domains 1 (LRIG1) in the tumor tissues of human pituitary tumor, and the effects of LRIG1 over-expression on the proliferation and apoptosis of human pituitary tumor cells induced by cisplatin (DDP). Methods The expression of LRIG1 in the tumor tissues and adjacent tissues of 45 cases with pituitary tumor was detected by immunohistochemistry, and the correlations between the positive expression of LRIG1 and the clinicopathological data of the patients were analyzed. In addition, the isolated human pituitary tumor cells were selected. The LRIG1 gene over-expression plasmid pEGFP-N1-LRIG1 was transfected into the cells by liposome-mediated gene transfection. The cells transfected with LRIG1 were screened, and meanwhile, the cells transfected with empty plasmid pEGFP-N1 were selected as a control group. The cells of the two groups were induced by 20 g/mL DDP, and 48 hours later, the cell apoptosis was detected by flow cytometry; the proliferation capacity was tested by plate cloning experiment; and the relative expressions of apoptosis-related proteins Bax, caspase-3 and Bcl2 in the cells were examined by Western blot analysis. Results LRIG1 in the tumor tissues of pituitary tumor was obviously lower than that of the adjacent tissues, and LRIG1 was significantly reduced in the invasive tumor tissues. Compared with the control group, after LRIG1 was over-expressed, the cell apoptosis rate significantly increased, the cell proliferation significantly decreased, and the levels of Bax and caspase-3 increased as well, while the level of Bcl2 decreased remarkably. Conclusion Over-expression of LRIG1 increases the apoptosis and inhibits the proliferation of human pituitary tumor cells induced by DDP. PMID- 29595453 TI - [Differential expression and correlation to cytokine expressions of FFAR4 in peritoneal and alveolar macrophages]. AB - Objective To investigate the expression level of free fatty acid receptor 4 (FFAR4) and its correlation with cytokine expressions in peritoneal macrophages and alveolar macrophages. Methods Peritoneal macrophages and alveolar macrophages were purified and collected using flow cytometry from adult BALB/c mice. Real time quantitative PCR was used to measure mRNA expression levels. The correlation between FFAR4 expression level and cytokine expression levels was analyzed using linear regression. Results The expression levels of FFAR4, interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) were significantly higher in the alveolar macrophages than in the peritoneal macrophages. In contrast, the expression levels of IL-10 and IL-6 were significantly lower in the alveolar macrophages than in the peritoneal macrophages. In the peritoneal macrophages, FFAR4 expression was positively correlated to the mRNA expressions of IL-10, IL-6 and TNF-alpha, but negatively correlated to IL-1 mRNA expression. In the alveolar macrophages, FFAR4 expression was positively correlated to the mRNA expressions of IL-1, IL-6 and TNF-alpha, but negatively correlated to IL-10 mRNA expression. Conclusion FFAR4 is differentially expressed and correlated to cytokine expressions in peritoneal macrophages and alveolar macrophages from BALB/c mice. PMID- 29595454 TI - [Knockdown of dopamine receptor D2 upregulates the expression of adiogenic genes in mouse primary mesencephalic neurons]. AB - Objective To study the effects of dopamine receptor D2 (DRD2) on the adipogenesis genes in mouse primary mesencephalic neurons. Methods The lentiviral vectors which expressed specific shRNA targeting DRD2 were constructed to decrease DRD2 expression in mouse primary mesencephalic neurons. High throughput sequencing (HTS) analysis was used to investigate gene expression changes between the DRD2 knock-down group and the negative control group. Real-time quantitative PCR (qRT PCR) and Western blot analysis were applied to verify the differently expressed genes. Fatty acids were measured by fatty acid detection kit. Results DRD2 expression was effectively down-regulated in mouse primary mesencephalic neurons by lentiviral vectors. HTS revealed adipogenesis genes were significantly up regulated after DRD2 down-regulation, mainly including delta(14)-sterol reductase, acetyl-coenzyme A synthetase, insulin-induced gene 1 protein and especially stearoyl-coenzyme A desaturase 1 (SCD1, 4-fold upregulated). The qRT PCR and Western blot analysis verified that SCD1 was upregulated 2.6 folds and 2 folds respectively by lentiviral DRD2-shRNA vectors. Moreover, the SCD1-related free fatty acids were significantly more increased than the negative control group. Conclusion DRD2 in primary mesencephalic neurons had a significant regulative effect on the adipogenesis genes. The up-regulation of SCD1 can accelerate the conversion of saturated fatty acids to monounsaturated fatty acids and prevent the damage of lipid toxicity to cells. PMID- 29595455 TI - [Mechanism of alpha-lipoic acid promoting iron efflux in substantia nigra cells of Parkinson's disease rats]. AB - Objective To observe the effect of alpha-lipoic acid (alpha-LA) on the expressions of iron regulatory protein 2 (IRP2) and ferroportin1 (FP1) in substantia nigra of rats with Parkinson's disease (PD) and explore the mechanism by which alpha-LA regulates iron efflux in substantia nigra cells of PD rat models. Methods Sixty healthy male SD rats were randomly divided into a sham group (n=15) and a model group (n=45). To establish the PD model, the rats of the model group were injected with 6-hydroxydopamine (6-OHDA) into their right striatum by the stereotactic technique, and the sham operation group was injected with the same dose of normal saline. Four weeks later, 30 model rats were randomly picked and divided into a PD model group (n=15) and a PD treatment group (n=15). The PD treatment group was intraperitoneally injected with alpha-LA (50 mg/kg) daily for 2 weeks, and the PD model group was given the same dose of saline. After 14 days of treatment, the left forelimb use rate was tested by cylinder test. The right middle cerebral substantia nigra was taken from each group, and the expression and distribution of tyrosine hydroxylase (TH) was detected by immunohistochemical staining; the number of iron positive cells was determined by Prussian blue staining; and the levels of IRP2 and FP1 were examined by Western blotting. Results Compared with the sham operation group, the left forelimb use rate of the PD model group was significantly reduced. The number of TH positive cells significantly decreased, and the number of iron positive cells in the substantia nigra significantly increased. The level of IRP2 significantly increased, and the level of FP1 decreased remarkably. Compared with PD model group, the left forelimb use rate of the PD treatment group was significantly raised. The number of TH positive cells was significantly elevated, and the number of iron positive cells in the substantia nigra was significantly reduced. The IRP2 level decreased and the FP1 level increased. Conclusion By decreasing the IRP2 level and via the IRP2/IRE pathway, alpha-LA can increase FP1 level, promote the outflow of iron ions from cells, and reduce iron deposition in the substantia nigra of PD model rats, thereby alleviating brain injury in PD rats induced by 6-OHDA. PMID- 29595456 TI - [Improvement and the mechanism of cardiac function by knockdown of ADAM10 in adriamycin-induced cardiomyopathy rats]. AB - Objective To study the role of a disintegrin and metalloproteinase10 (ADAM10) in shedding neural cadherin (N-cadherin) and develop an approach to interfere the process of ventricular remodeling in adriamycin-induced cardiomyopathy (ACM) rats. Methods In a rat model of ACM, the effects of intraperitoneal injection of the lentiviral RNAi vector of ADAM10 on the morphology of cardiomyocytes and contractile function were observed by HE staining and color Doppler echocardiography. The expressions of N-cadherin and C-terminal fragment 1 (CTF1) were detected by Western blotting and immunohistochemistry. Results In the in vivo experiment, a large amount of fluorescence was seen in the isolated primary cardiomyocytes, which indicated that the transfection in the rat model was successful. In the treatment group, the morphology of cardiomyocytes and function of the heart were evidently improved, N-cadherin protein expression was remarkably up-regulated and CTF1 protein was obviously down-regulated compared with the model group. Conclusion Knock-down of ADAM10 increases N-cadherin expression and decreases CTF1 expression, thus improves cardiac function in the rat model of ACM. PMID- 29595457 TI - [Neurotrophin-3 enhances the osteogenesis ability of human bone marrow mesenchymal stem cells stimulated by lipopolysaccharide]. AB - Objective To investigate the protective effect of neurotrophin-3 (NT-3) on human bone marrow mesenchymal stem cells (hBMSCs) and its ability to promote the differentiation of hBMSCs into osteoblasts in the inflammatory environment. Methods The cell inflammation model was established by lipopolysaccharide (LPS). The hBMSCs without any stimulation was defined as the inflammatory control group; the hBMSCs stimulated by 100 ng/mL human NT-3 recombinant protein as the NT-3 group; the hBMSCs stimulated by 100 mmol/L pyrvinium pamoate (PP) for 12 hours and then stimulated by 100 ng/mL human NT-3 recombinant protein as the Wnt inhibitor group; the normal cultured hBMSCs as the normal control group. We performed the experiment of osteoblast induction on all groups. CCK-8 assay was used to detect the proliferation of hBMSCs; the fluorescein isothiocyanate labeled annexin V/propidium iodide (Annexin V-FITC/PI) double labeling combined with flow cytometry was used to detect the apoptosis of hBMSCs; ELISA was used to detect the protein levels of runt-related transcription factor 2 (RUNX2) protein and alkaline phosphatase (ALP); and the alizarin red staining experiment was conducted to detect the ability of calcium nodule formation. Results Compared with the inflammatory control group, the proliferative activity of hBMSCs in NT-3 group significantly increased, the apoptosis obviously decreased, and the contents of RUNX2 and ALP, as well as the intensity of alizarin red staining in NT-3 group evidently rose. Compared with the NT-3 group, the proliferative activity of hBMSCs in the Wnt inhibitor group was inhibited, the cell apoptosis was promoted, and the contents of RUNX2 and ALP, as well as the intensity of alizarin red staining in the Wnt inhibitor group were reduced remarkably. Conclusion NT-3 can protect hBMSCs from anti-inflammatory damage and promote the differentiation of hBMSCs into osteoblasts. PMID- 29595458 TI - [Nucleocytoplasmic translocation of ING5 protein in breast cancer and its correlation with poor clinicopathological characteristics of breast cancer]. AB - Objective To investigate the nucleocytoplasmic translocation of inhibitor of growth family member 5 (ING5) gene in human breast cancer and the negative correlation between the nuclear high expression of ING5 protein and the clinicopathological characteristics of breast cancer. Methods We collected 260 cases of clinical primary breast cancer, 55 cases of metastatic cancer in lymph node, 61 cases of breast fibroadenoma, 110 cases of adenomatosis, and 91 cases of para-cancerous tissues. With the tissue microarrays, we detected ING5 expression in the nucleus and cytoplasm through immunohistochemistry, and statistically analyzed the correlations of nuclear and cytoplasmic ING5 expression with the clinicopathological characteristics of breast cancer. Results The expression of nuclear ING5 in the para-cancerous tissues was obviously higher than that in the fibroadenoma, adenomatosis and primary breast cancer; it was higher in the adenomatosis than in the primary breast cancer, and higher in the primary breast cancer than in the metastatic cancer in lymph node. The cytoplasmic ING5 expression in the para-carcinoma tissue was higher than that in the fibroadenoma, adenomatosis and primary breast cancer. These data suggested the nucleocytoplasmic translocation of ING5 protein in breast cancer. Moreover, nuclear ING5 high expression was negatively correlated with distant metastasis and positively with P53 expression, while cytoplasmic ING5 high expression was positively correlated with tumor size and estrogen receptor expression. The cytoplasm ING5 expression of triple-negative breast cancer was lower than that in the non-triple-negative breast cancer. Conclusion Nucleocytoplasmic translocation of ING5 protein occurs in breast cancer, and the high expression of nuclear ING5 is inversely related to some poor clinicopathological behaviors of breast cancer. PMID- 29595459 TI - [Pseudolaric acid B induces G2/M arrest and inhibits invasion and migration in HepG2 hepatoma cells]. AB - Objective To investigate the mechanisms of pseudolaric acid B (PAB) blocks cell cycle and inhibits invasion and migration in human hepatoma HepG2 cells. Methods The proliferation effect of PAB on HepG2 cells was evaluated by MTT assay. The effect of PAB on the cell cycle of HepG2 cells was analyzed by flow cytometry. Immunofluorescence cytochemical staining was applied to observe the effect of PAB on the alpha-tubulin polymerization and expression in HepG2 cells. TranswellTM chamber invasion assay and wound healing assay were performed to detect the influence of PAB on the migration and invasion ability of HepG2 cells. Western blotting was used to determine the expressions of alpha-tubulin, E-cadherin and MMP-9 in HepG2 cells after treated with PAB. Results PAB inhibited the proliferation of HepG2 cells in a dose-dependent manner and blocked the cell cycle in G2/M phase. PAB significantly changed the polymerization and decreased the expression of alpha-tubulin. The capacities of invasion and migration of HepG2 cells treated by PAB were significantly depressed. The protein levels of alpha-tubulin and MMP-9 decreased while the E-cadherin protein level increased. Conclusion PAB can inhibits the proliferation of HepG2 cells by down-regulating the expression of alpha-tubulin and influencing its polymerization, arresting HepG2 cells in G2/M phase. Meanwhile, PAB also can inhibit the invasion and migration of HepG2 cells by lowering cytoskeleton alpha-tubulin and MMP-9, and increasing E-cadherin.

AB - Objective To investigate the distribution characteristics of Rh blood group in 51 283 cases of inpatients and voluntary blood donors. Methods Micro-column gel test was used to detect RhD, RhE, Rhe, RhC, Rhc antigen in 31 818 cases of hospitalized patients and 19 465 cases of voluntary blood donors. Results There were significant differences in Rh blood type distribution between inpatients and voluntary blood donors. The mainly phenotype of Rh blood group in the inpatients were DCCee (41.64%) and DCcEe (36.58%), and Rh blood type in voluntary blood donors were DCCee (41.11%) and DCcEe (37.11%). There were noticeable differences in Rh blood group and ABO phenotype between inpatients and voluntary blood donors. The mainly phenotype of the RhD positive patients were CcEe (36.58%) and CCee (41.64%). However, the mainly phenotype of RhD negative patients were ccee (54.30%) and Ccee (30.86%). Additionally, obvious difference of Rh blood group was seen between patients in haematology department and all patients. The voluntary blood donors from different areas including Hefei, Guangzhou, Nanning and Xi'an showed significant different Rh blood group distribution. On the contrary, no obvious difference of Rh blood group was found between Xianyang and Xi'an. Conclusion The differences of Rh blood group distribution have been found in different populations, departments and areas, which make it extremely important to detect Rh blood group in clinical transfusion.

AB - Building on a similar effort in California, Catalyst for Payment Reform is proposing a standardized set of 50 ACO measures. A timely development. In the first quarter of last year, an estimated 19.1 million lives were covered by 715 commercial ACOs, compared with 17.2 million lives a year earlier. PMID- 29595465 TI - A Conversation With Mai Pham, MD. Payment Innovation at Anthem: Downside Risk Will Be Rewarded. AB - The insurer's vice president of provider alignment solutions says: "We're going to start to signal to providers that if you are going to stay an upside-only arrangement, we're not going to give you free money forever in the form of the care-coordination fees that we've been paying out. They're not an entitlement." PMID- 29595466 TI - Real-World Evidence Not Quite Believable Enough. AB - In theory, this approach could help untangle some knotty cost and quality concerns about medications as they move from clinical trials and into clinical use. But there's a credibility issue: The perception that much of the research is biased and that the studies are designed so the results serve the interests of the sponsors. PMID- 29595467 TI - Fall Prevention Hits Stumbling Blocks. AB - Implementation of efforts to screen older people for fall risk-and to intervene before falls occur-have been scattershot at best.

PMID- 29595469 TI - Assessing Provider Partnerships For Accountable Care Organizations. AB - PURPOSE: Understand current provider approaches to the evaluation of various partnerships under accountable care contracts and create a framework to help accountable care organizations (ACOs) better assess their partnerships. DESIGN: Study included (1) an in-depth literature review of materials describing high value health care organizations as a foundation for draft framework development, (2) an expert panel convened to evaluate the framework and help prioritize provider types to evaluate, and (3) interviews with representatives of ACOs and entities representing various types of health care providers. METHODOLOGY: Authors created a draft partnership framework derived from the literature review for expert panel feedback. An updated draft framework was then shared with active ACO leaders prior to qualitative interviews. All interviews were transcribed and coded using a mixed-methods analysis platform. RESULTS: We found little research that took a comprehensive view of health care provider competencies and characteristics and by extension few resources to help ACOs fill competency gaps through partnerships. The ACOs interviewed were all actively engaged in provider partnerships and were learning and establishing best practices for provider partnerships. CONCLUSIONS: Accountable care offers incentives for entities to improve the cost and quality of health care. To accomplish this in an effective way, ACOs must recognize the needs of their assigned populations and work to provide comprehensive care management across the spectrum of provider types. Accomplishing this will also require ACOs to create novel partnership arrangements and learn how to manage populations most effectively. ACOs need a framework for evaluating potential partners that will help risk-bearing providers establish the partnerships that will enable them to achieve their goals. This paper makes specific recommendations on how state and federal policy could facilitate better and more effective provider partnerships.

AB - Different coding strategies are used to represent odor information at various stages of the mammalian olfactory system. A temporal latency code represents odor identity in olfactory bulb (OB), but this temporal information is discarded in piriform cortex (PCx) where odor identity is instead encoded through ensemble membership. We developed a spiking PCx network model to understand how this transformation is implemented. In the model, the impact of OB inputs activated earliest after inhalation is amplified within PCx by diffuse recurrent collateral excitation, which then recruits strong, sustained feedback inhibition that suppresses the impact of later-responding glomeruli. We model increasing odor concentrations by decreasing glomerulus onset latencies while preserving their activation sequences. This produces a multiplexed cortical odor code in which activated ensembles are robust to concentration changes while concentration information is encoded through population synchrony. Our model demonstrates how PCx circuitry can implement multiplexed ensemble-identity/temporal-concentration odor coding.

AB - Despite the intrinsically stochastic nature of damage, sensory organs recapitulate normal architecture during repair to maintain function. Here we present a quantitative approach that combines live cell-lineage tracing and multifactorial classification by machine learning to reveal how cell identity and localization are coordinated during organ regeneration. We use the superficial neuromasts in larval zebrafish, which contain three cell classes organized in radial symmetry and a single planar-polarity axis. Visualization of cell-fate transitions at high temporal resolution shows that neuromasts regenerate isotropically to recover geometric order, proportions and polarity with exceptional accuracy. We identify mediolateral position within the growing tissue as the best predictor of cell-fate acquisition. We propose a self-regulatory mechanism that guides the regenerative process to identical outcome with minimal extrinsic information. The integrated approach that we have developed is simple and broadly applicable, and should help define predictive signatures of cellular behavior during the construction of complex tissues.

Although the non-cell-autonomous effect of RTT astrocytes on neurons was documented, cell-autonomous phenotypes and mechanisms within RTT astrocytes are not well understood. We report that spontaneous calcium activity is abnormal in RTT astrocytes in vitro, in situ, and in vivo. Such abnormal calcium activity is mediated by calcium overload in the endoplasmic reticulum caused by abnormal store operated calcium entry, which is in part dependent on elevated expression of TRPC4. Furthermore, the abnormal calcium activity leads to excessive activation of extrasynaptic NMDA receptors (eNMDARs) on neighboring neurons and increased network excitability in Mecp2 knockout mice. Finally, both the abnormal astrocytic calcium activity and the excessive activation of eNMDARs are caused by Mecp2 deletion in astrocytes in vivo. Our findings provide evidence that abnormal calcium homeostasis is a key cell-autonomous phenotype in RTT astrocytes, and reveal its mechanism and consequence. PMID- 29595473 TI - Topoisomerase VI senses and exploits both DNA crossings and bends to facilitate strand passage. AB - Type II topoisomerases manage DNA supercoiling and aid chromosome segregation using a complex, ATP-dependent duplex strand passage mechanism. Type IIB topoisomerases and their homologs support both archaeal/plant viability and meiotic recombination. Topo VI, a prototypical type IIB topoisomerase, comprises two Top6A and two Top6B protomers; how these subunits cooperate to engage two DNA segments and link ATP turnover to DNA transport is poorly understood. Using multiple biochemical approaches, we show that Top6B, which harbors the ATPase activity of topo VI, recognizes and exploits the DNA crossings present in supercoiled DNA to stimulate subunit dimerization by ATP. Top6B self-association in turn induces extensive DNA bending, which is needed to support duplex cleavage by Top6A. Our observations explain how topo VI tightly coordinates DNA crossover recognition and ATP binding with strand scission, providing useful insights into the operation of type IIB topoisomerases and related meiotic recombination and GHKL ATPase machineries. PMID- 29595474 TI - Size uniformity of animal cells is actively maintained by a p38 MAPK-dependent regulation of G1-length. AB - Animal cells within a tissue typically display a striking regularity in their size. To date, the molecular mechanisms that control this uniformity are still unknown. We have previously shown that size uniformity in animal cells is promoted, in part, by size-dependent regulation of G1 length. To identify the molecular mechanisms underlying this process, we performed a large-scale small molecule screen and found that the p38 MAPK pathway is involved in coordinating cell size and cell cycle progression. Small cells display higher p38 activity and spend more time in G1 than larger cells. Inhibition of p38 MAPK leads to loss of the compensatory G1 length extension in small cells, resulting in faster proliferation, smaller cell size and increased size heterogeneity. We propose a model wherein the p38 pathway responds to changes in cell size and regulates G1 exit accordingly, to increase cell size uniformity.

AB - INTRODUCTION: Brodie's syndrome consists in a transverse occlusal discrepancy in relation with an excessive width of the maxilla, a narrow mandible or a combination of both, leading to lateral scissors bite. This kind of infrequent malocclusion is usually treated by orthodontics alone in children. In adults, additional orthognathic surgery id often required. We present a case of unilateral Brodie's syndrome treated by surgical contraction of the maxillae. OBSERVATION: A 22-year-old patient presented with a left scissors bite and severe unilateral molar overbite. After failure of an attempt to ingress the left molars by help of a sub-apical corticotomy and anchorage mini-screws, the patient was referred for surgery. The mandible being considered as normal, a segmented Le Fort I osteotomy was planned, combining a contraction (4mm) and an impaction (4mm) of the left maxilla. This allowed for an immediate correction of the skeletal discrepancy and for the achievement of orthodontics in less than 6 months. DISCUSSION: Le Fort I osteotomy provides a good access to the sagittal suture. Maxillary contraction is an uncommon procedure that enables a quick management of scissors bite and doesn't need any patient cooperation. Treatment time is reduced and the need for intraoral devices is limited.

AB - During development, coordinated cell behaviors orchestrate tissue and organ morphogenesis. Detailed descriptions of cell lineages and behaviors provide a powerful framework to elucidate the mechanisms of morphogenesis. To study the cellular basis of limb development, we imaged transgenic fluorescently-labeled embryos from the crustacean Parhyale hawaiensis with multi-view light-sheet microscopy at high spatiotemporal resolution over several days of embryogenesis. The cell lineage of outgrowing thoracic limbs was reconstructed at single-cell resolution with new software called Massive Multi-view Tracker (MaMuT). In silico clonal analyses suggested that the early limb primordium becomes subdivided into anterior-posterior and dorsal-ventral compartments whose boundaries intersect at the distal tip of the growing limb. Limb-bud formation is associated with spatial modulation of cell proliferation, while limb elongation is also driven by preferential orientation of cell divisions along the proximal-distal growth axis. Cellular reconstructions were predictive of the expression patterns of limb development genes including the BMP morphogen Decapentaplegic. PMID- 29595478 TI - Abortion: access and safety worldwide.

PMID- 29595518 TI - Magnetic graphene enabled tunable microwave absorber via thermal control. AB - By synthesizing nitrogen-doped graphene (NG) via a facile thermal annealing method, a fine control of the amount and location of doped nitrogen as well as the oxygen-containing functional groups is achieved with varying annealing temperature. The favorable magnetic properties have been achieved for N-doped rGO samples obtained at two temperatures of all NG samples, i.e., 500 degrees C and 900 degrees C with saturation magnetization of 0.63 emu g-1 and 0.67 emu g-1 at 2 K, respectively. This is attributed to the optimized competition of the N doping and reduction process at 500 degrees C and the dominated reduction process at 900 degrees C. NG obtained at 300 degrees C affords the best overall absorbing performance: when the absorber thickness is 3.0 mm, the maximum absorption was -24.6 dB at 8.51 GHz, and the absorption bandwidth was 4.89 GHz (7.55-12.44 GHz) below -10 dB. It owes its large absorbing intensity to the good impedance match and significant dielectric loss. The broad absorption bandwidth benefits from local fluctuations of dielectric responses contributed by competing mechanisms. Despite the significant contribution from materials loss to the absorption, the one quarter-wavelength model is found to be responsible for the reflection loss peak positions. Of particular significance is that an appropriate set of electromagnetic parameters associated with reasonable reduction is readily accessible by convenient control of annealing temperature to modulate the microwave absorbing features of graphene. Thus, NG prepared by thermal annealing promises to be a highly efficient microwave absorbent. PMID- 29595521 TI - Can disorder act as a chemical pressure? An optical study of the Hubbard model. AB - The optical properties have been studied using the dynamical mean-field theory on a disordered Hubbard model. Despite the fact that disorder turns a metal to an insulator in high dimensional correlated materials, we notice that it can enhance certain metallic behavior as if a chemical pressure is applied to the system resulting in an increase of the effective lattice bandwidth (BW). We study optical properties in such a scenario and compare results with experiments where the BW is changed through isovalent chemical substitution (keeping electron filling unaltered) and obtain remarkable similarities vindicating our claim. We also make the point that these similarities differ from some other forms of BW tuned optical effects. PMID- 29595511 TI - The global tuberculosis epidemic and progress in care, prevention, and research: an overview in year 3 of the End TB era. AB - Tuberculosis is the number one cause of death from infectious disease globally and drug-resistant forms of the disease are a major risk to global health security. On the occasion of World Tuberculosis Day (March 24, 2018), we provide an up-to-date review of the status of the tuberculosis epidemic, recommended diagnostics, drug treatments and vaccines, progress in delivery of care and prevention, progress in research and development, and actions needed to accelerate progress. This Review is presented in the context of the UN Sustainable Development Goals and WHO's End TB Strategy, which share the aim of ending the global tuberculosis epidemic. In 2016, globally there were an estimated 10.4 million new cases of tuberculosis, and 600 000 new cases with resistance to rifampicin (the most powerful first-line drug). All countries and age groups are affected by tuberculosis, but most cases (90%) in 2016 were in adults, and almost two-thirds were accounted for by seven countries: India, Indonesia, China, Philippines, Pakistan, South Africa, and Nigeria. The sex ratio (male to female) was 1.9 and 10% of patients with newly diagnosed tuberculosis were also HIV-positive. There were 1.7 million deaths from tuberculosis in 2016, including 0.4 million deaths among people co-infected with HIV (officially classified as deaths caused by HIV/AIDS). Progress in care and prevention means that the global mortality rate (deaths per 100 000 people per year) is decreasing by 3.4% per year and incidence (new cases per 100 000 people per year) is decreasing by 1.9% per year. From 2000 to 2016, the annual global number of tuberculosis deaths decreased by 24% and the mortality rate declined by 37%. Worldwide, an estimated 53 million deaths were averted through successful treatment. Nonetheless, major gaps in care and prevention remain. For example, the 6.3 million new cases of tuberculosis reported globally in 2016 represented only 61% of the estimated incidence; only one in five of the estimated number of people with drug-resistant tuberculosis was enrolled in treatment. Pipelines for new diagnostics, drugs, and vaccines are progressing, but slowly. Actions needed to accelerate progress towards global milestones and targets for reductions in the burden of tuberculosis disease set for 2020, 2025, 2030, and 2035 include closing coverage gaps in testing, reporting of cases, and overall access to health care, especially in countries that account for the largest share of the global gap; multisectoral efforts to reduce prevalence of major risk factors for infection and disease; and increased investment in research and development.

AB - Blue-phase liquid crystals (BPLCs) are regarded as a potential candidate for the next generation of optical devices, but they appear in a narrow temperature range, which restricts their applicability. The nanoparticle (NP) stabilization of BPLCs, is usually about either simple-cubic BP (BPII) or body-centered-cubic BP (BPI). Hence, NP-stabilized BPIIs and BPIs possessing wide temperature ranges have been scarcely reported. Here, nickel nanoparticles (Ni NPs) were synthesized and introduced into a BPLC. The concentration-dependent temperature range effects of Ni NPs on the BPLC were investigated. A trace amount of Ni NPs could stabilize the BPLC and increase the temperature ranges of BPII and BPI; this is attributable to the Ni NPs tending to be trapped at the joints of the disclination lines, as a result of the elastic interaction, stabilizing the overall lattice structure of the BPLC. When doped with 0.05 wt% Ni NPs, the mixture shows a wider range with 7.7 degrees C than the range with 5.9 degrees C of the BPLC without Ni NPs. Meanwhile, the phase sequence and range of the aforementioned phases are reproducible upon heating and cooling, which shows that the BPLCs doped with Ni NPs are thermodynamically stable. PMID- 29595522 TI - Armours for soft bodies: how far can bioinspiration take us? AB - The development of armour is as old as the dawn of civilization. Early man looked to natural structures to harvest or replicate for protection, leaning on millennia of evolutionary developments in natural protection. Since the advent of more modern weaponry, Armor development has seemingly been driven more by materials research than bio-inspiration. However, parallels can still be drawn between modern bullet-protective armours and natural defensive structures. Soft armour for handgun and fragmentation threats can be likened to mammalian skin, and similarly, hard armour can be compared with exoskeletons and turtle shells. Via bio-inspiration, it may be possible to develop structures previously un researched for ballistic protection. This review will cover current modern ballistic protective structures focusing on energy dissipation and absorption methods, and their natural analogues. As all armour is a compromise between weight, flexibility and protection, the imbricated structure of scaled skin will be presented as a better balance between these factors.

AB - Broad photoluminescence (PL) emission, a large Stokes shift and extremely long lived radiative lifetimes are the characteristics of ternary I-III-VI semiconductor nanocrystals (NCs), such as CuInS2 and AgInS2. However, the lack of understanding regarding the intriguing PL mechanisms and photo-carrier dynamics limits their further applications. Here, AgInS2 and AgInS2/ZnS NCs were chemically synthesized and their carrier dynamics were studied by time-resolved PL spectroscopy. The results demonstrated that the surface defect state, which contributed dominantly to the non-radiative decay processes, was effectively passivated through ZnS alloying. Femtosecond transient absorption spectroscopy was also used to investigate the carrier dynamics, revealing the electron storage at the surface state and donor state. Furthermore, the two photon absorption properties of AgInS2 and AgInS2/ZnS NCs were measured using an open-aperture Z scan technique. The improved third-order nonlinear susceptibility [Formula: see text] of AgInS2 through ZnS alloying demonstrates potential application in two photon PL biological imaging.

AB - Graphene-structure WSe2 nano-films (NFMs) were prepared by magnetron sputtering and vacuum selenization. The as synthesized WSe2 NFMs were characterized using various techniques such as SEM, XRD and EDS. Our work provides a simple and effective method to prepare WSe2 NFMs. We have observed the high photo responsivity of WSe2 NFMs up to 10 A W-1, which is 40% higher than the previously reported data. Our photoelectrochemical tests demonstrate that WSe2 NFMs have excellent photoelectric properties, indicating that NFMs have a wide application potentialsin solar cells and optoelectronic devices. PMID- 29595510 TI - Safety and immunogenicity of the novel tuberculosis vaccine ID93 + GLA-SE in BCG vaccinated healthy adults in South Africa: a randomised, double-blind, placebo controlled phase 1 trial. AB - BACKGROUND: A vaccine that prevents pulmonary tuberculosis in adults is needed to halt transmission in endemic regions. This trial aimed to assess the safety and immunogenicity of three administrations at varying doses of antigen and adjuvant of an investigational vaccine (ID93 + GLA-SE) compared with placebo in previously BCG-vaccinated healthy adults in a tuberculosis endemic country. METHODS: In this randomised, double-blind, placebo-controlled phase 1 trial, we enrolled HIV negative, previously BCG-vaccinated adults (aged 18-50 years), with no evidence of previous or current tuberculosis disease, from among community volunteers in the Worcester region of Western Cape, South Africa. Participants were randomly assigned to receive varying doses of ID93 + GLA-SE or saline placebo at day 0, day 28, and day 112. Enrolment into each cohort was sequential. Cohort 1 participants were Mycobacterium tuberculosis uninfected (as defined by negative QuantiFERON [QFT] status), and received 10 MUg ID93 plus 2 MUg GLA-SE, or placebo; in cohorts 2-4, QFT-negative or positive participants received escalating doses of vaccine or placebo. Cohort 2 received 2 MUg ID93 plus 2 MUg GLA-SE; cohort 3 received 10 MUg ID93 plus 2 MUg GLA-SE; and cohort 4 received 10 MUg ID93 plus 5 MUg GLA-SE. Dose cohort allocation was sequential; randomisation within a cohort was according to a randomly-generated sequence (3 to 1 in cohort 1, 5 to 1 in cohorts 2-4). The primary endpoint was safety of ID93 + GLA-SE as defined by solicited and unsolicited adverse events up to 28 days after each study injection and serious adverse events for the duration of the study. Specific immune responses were measured by intracellular cytokine staining, flow cytometry, and ELISA. All analyses were done according to intention to treat, with additional per-protocol analyses for immunogenicity outcomes. This trial is registered with ClinicalTrials.gov, number NCT01927159. FINDINGS: Between Aug 30, 2013, and Sept 4, 2014, 227 individuals consented to participate; 213 were screened (three participants were not included as study number was already met and 11 withdrew consent before screening occurred, mostly due to relocation or demands of employment). 66 healthy, HIV-negative adults were randomly allocated to receive the vaccine (n=54) or placebo (n=12). All study participants received day 0 and day 28 study injections; five participants did not receive an injection on day 112. ID93 + GLA-SE was well tolerated; no severe or serious vaccine related adverse events were recorded. Vaccine dose did not affect frequency or severity of adverse events, but mild injection site adverse events and flu-like symptoms were common in M tuberculosis-infected participants compared with uninfected participants. Vaccination induced durable antigen-specific IgG and Th1 cellular responses, which peaked after two administrations. Vaccine dose did not affect magnitude, kinetics, or profile of antibody and cellular responses. Earlier boosting and greater T-cell differentiation and effector-like profiles were seen in M tuberculosis-infected than in uninfected vaccinees. INTERPRETATION: Escalating doses of ID93 + GLA-SE induced similar antigen specific CD4-positive T cell and humoral responses, with an acceptable safety profile in BCG-immunised, M tuberculosis-infected individuals. The T-cell differentiation profiles in M tuberculosis-infected vaccinees suggest priming through natural infection. While cohort sample sizes in this phase 1 trial were small and results should be interpreted in context, these data support efficacy testing of two administrations of the lowest (2 MUg) ID93 vaccine dose in tuberculosis endemic populations.

AB - Proteins perform a huge number of central functions in living organisms, thus all the new techniques allowing their precise, fast and accurate characterization at single-molecule level certainly represent a burst in proteomics with important biomedical impact. In this review, we describe the recent progresses in the developing of nanopore based devices for protein sequencing. We start with a critical analysis of the main technical requirements for nanopore protein sequencing, summarizing some ideas and methodologies that have recently appeared in the literature. In the last sections, we focus on the physical modelling of the transport phenomena occurring in nanopore based devices. The multiscale nature of the problem is discussed and, in this respect, some of the main possible computational approaches are illustrated. PMID- 29595516 TI - A Rare Cause of Congenital Adrenal Hyperplasia: Clinical and Genetic Findings and Follow-up Characteristics of Six Patients with 17-Hydroxylase Deficiency Including Two Novel Mutations AB - Objective: 17alpha-hydroxylase/17,20 lyase deficiency (17OHD) is a rare form of congenital adrenal hyperplasia (CAH), characterized by hypertension and varying degrees of ambiguous genitalia and delayed puberty. The disease is associated with bi-allelic mutations in the CYP17A1 gene located on chromosome 10q24.3. We aimed to present clinical and genetic findings and follow-up and treatment outcomes of 17OHD patients. Methods: We evaluated six patients with 17OHD from five families at presentation and at follow up. Standard deviation score of all auxological measurements was calculated according to national data and karyotype status. CYP17A1 gene sequence alterations were investigated in all patients. Results: The mean (+/-standard deviation) age of patients at presentation and follow-up time was 14.6+/-4.2 and 5.0+/-2.7 years respectively. Five patients were referred to us because of delayed puberty and primary amenorrhea and four for hypertension. One novel single nucleotide insertion leading to frame shift and another novel variant occurring at an ultra rare position, leading to a missense change, are reported, both of which caused 17OHD deficiency. Steroid replacement was started. The three patients with 46,XY karyotype who were raised as females underwent gonadectomy. Osteoporosis was detected in five patients. Four patients needed antihypertensive treatment. Improvement in osteoporosis was noted with gonadal steroid replacement and supportive therapy. Conclusion: 17OHD, a rare cause of CAH, should be kept in mind in patients with pubertal delay and/or hypertension. Patients with 46,XY who are raised as females require gonadectomy. Due to late diagnosis, psychological problems, gender selection, hypertension and osteoporosis are important health problems affecting a high proportion of these patients. PMID- 29595517 TI - Parental Perception of Terminology of Disorders of Sex Development in Western Turkey AB - Objective: Disorders of sex development (DSD) is a nomenclature intended to defeat the discomfort of families and patients and has found worldwide usage. The aim of this study was to address the perception and usage of terminology among the parents of DSD patients in a tertiary center in western Turkey. Methods: The records of the DSD council (multidisciplinary team where each patient with DSD is discussed) between years 2008-2015 were reviewed retrospectively. Data including details of the management process, patient characteristics and follow-up details were noted. Then inquiries reflecting parental perception about terminology were implemented during clinical visits. Results: In total, 121 patients were evaluated in monthly meetings of the DSD council and 79 inquiries were completed. Fifty-one percent of the families admitted knowing the terms DSD, ambiguous genitalia, "dubious genitals" and intersex. However, only 2% preferred using DSD, 6% intersex and 14% ambiguous genitalia. Fifty-two percent of the parents used a disease name in Latin (mostly hypospadias) addressing the disorder. The offspring of 69% of the parents who were familiar with the name "dubious genitals" were diagnosed in the neonatal period. The preferred terminology used by parents was strongly associated with the terminology used most commonly in the medical speciality their child most often attended. Conclusion: Each country has its own social norms. We suggest therefore that local committees including medical professionals, patients and families should be employed to develop proper terminology. PMID- 29595525 TI - Electrical and optical evaluation of n-type doping in In x Ga(1-x)P nanowires. AB - To harvest the benefits of III-V nanowires in optoelectronic devices, the development of ternary materials with controlled doping is needed. In this work, we performed a systematic study of n-type dopant incorporation in dense In x Ga(1 x)P nanowire arrays using tetraethyl tin (TESn) and hydrogen sulfide (H2S) as dopant precursors. The morphology, crystal structure and material composition of the nanowires were characterized by use of scanning electron microscopy, transmission electron microscopy and energy dispersive x-ray analysis. To investigate the electrical properties, the nanowires were broken off from the substrate and mechanically transferred to thermally oxidized silicon substrates, after which electron beam lithography and metal evaporation were used to define electrical contacts to selected nanowires. Electrical characterization, including four-probe resistivity and Hall effect, as well as back-gated field effect measurements, is combined with photoluminescence spectroscopy to achieve a comprehensive evaluation of the carrier concentration in the doped nanowires. We measure a carrier concentration of ~1 * 1016 cm-3 in nominally intrinsic nanowires, and the maximum doping level achieved by use of TESn and H2S as dopant precursors using our parameters is measured to be ~2 * 1018 cm-3, and ~1 * 1019 cm-3, respectively (by Hall effect measurements). Hence, both TESn and H2S are suitable precursors for a wide range of n-doping levels in In x Ga(1-x)P nanowires needed for optoelectronic devices, grown via the vapor-liquid-solid mode. PMID- 29595526 TI - Theory of in-plane current induced spin torque in metal/ferromagnet bilayers. AB - Using a semiclassical approach that simultaneously incorporates the spin Hall effect (SHE), spin diffusion, quantum well states, and interface spin-orbit coupling (SOC), we address the interplay of these mechanisms as the origin of the spin-orbit torque (SOT) induced by in-plane currents, as observed in the normal metal/ferromagnetic metal bilayer thin films. Focusing on the bilayers with a ferromagnet much thinner than its spin diffusion length, such as Pt/Co with ~10 nm thickness, our approach addresses simultaneously the two contributions to the SOT, namely the spin-transfer torque (SHE-STT) due to SHE-induced spin injection, and the inverse spin Galvanic effect spin-orbit torque (ISGE-SOT) due to SOC induced spin accumulation. The SOC produces an effective magnetic field at the interface, hence it modifies the angular momentum conservation expected for the SHE-STT. The SHE-induced spin voltage and the interface spin current are mutually dependent and, hence, are solved in a self-consistent manner. The result suggests that the SHE-STT and ISGE-SOT are of the same order of magnitude, and the spin transport mediated by the quantum well states may be an important mechanism for the experimentally observed rapid variation of the SOT with respect to the thickness of the ferromagnet. PMID- 29595509 TI - Comparison of different treatments for isoniazid-resistant tuberculosis: an individual patient data meta-analysis. AB - BACKGROUND: Isoniazid-resistant, rifampicin-susceptible (INH-R) tuberculosis is the most common form of drug resistance, and is associated with failure, relapse, and acquired rifampicin resistance if treated with first-line anti-tuberculosis drugs. The aim of the study was to compare success, mortality, and acquired rifampicin resistance in patients with INH-R pulmonary tuberculosis given different durations of rifampicin, ethambutol, and pyrazinamide (REZ); a fluoroquinolone plus 6 months or more of REZ; and streptomycin plus a core regimen of REZ. METHODS: Studies with regimens and outcomes known for individual patients with INH-R tuberculosis were eligible, irrespective of the number of patients if randomised trials, or with at least 20 participants if a cohort study. Studies were identified from two relevant systematic reviews, an updated search of one of the systematic reviews (for papers published between April 1, 2015, and Feb 10, 2016), and personal communications. Individual patient data were obtained from authors of eligible studies. The individual patient data meta analysis was performed with propensity score matched logistic regression to estimate adjusted odds ratios (aOR) and risk differences of treatment success (cure or treatment completion), death during treatment, and acquired rifampicin resistance. Outcomes were measured across different treatment regimens to assess the effects of: different durations of REZ (<=6 months vs >6 months); addition of a fluoroquinolone to REZ (fluoroquinolone plus 6 months or more of REZ vs 6 months or more of REZ); and addition of streptomycin to REZ (streptomycin plus 6 months of rifampicin and ethambutol and 1-3 months of pyrazinamide vs 6 months or more of REZ). The overall quality of the evidence was assessed using GRADE methodology. FINDINGS: Individual patient data were requested for 57 cohort studies and 17 randomised trials including 8089 patients with INH-R tuberculosis. We received 33 datasets with 6424 patients, of which 3923 patients in 23 studies received regimens related to the study objectives. Compared with a daily regimen of 6 months of (H)REZ (REZ with or without isoniazid), extending the duration to 8-9 months had similar outcomes; as such, 6 months or more of (H)REZ was used for subsequent comparisons. Addition of a fluoroquinolone to 6 months or more of (H)REZ was associated with significantly greater treatment success (aOR 2.8, 95% CI 1.1-7.3), but no significant effect on mortality (aOR 0.7, 0.4-1.1) or acquired rifampicin resistance (aOR 0.1, 0.0-1.2). Compared with 6 months or more of (H)REZ, the standardised retreatment regimen (2 months of streptomycin, 3 months of pyrazinamide, and 8 months of isoniazid, rifampicin, and ethambutol) was associated with significantly worse treatment success (aOR 0.4, 0.2-0.7). The quality of the evidence was very low for all outcomes and treatment regimens assessed, owing to the observational nature of most of the data, the diverse settings, and the imprecision of estimates. INTERPRETATION: In patients with INH R tuberculosis, compared with treatment with at least 6 months of daily REZ, addition of a fluoroquinolone was associated with better treatment success, whereas addition of streptomycin was associated with less treatment success; however, the quality of the evidence was very low. These results support the conduct of randomised trials to identify the optimum regimen for this important and common form of drug-resistant tuberculosis.

AB - In today's era of nursing, the role of a unique disciplinary knowledge that is grounded in philosophy is essential to inform nursing practice, fill knowledge gaps, improve the quality of nursing education, and guide the theoretical development of nursing. Realism and relativism have contributed to the development of the nursing discipline by providing the basis of evidence-based nursing practice, nursing research, nursing education, and theoretical construction. This article explores the role of realism and relativism in the development of the discipline of nursing and presents their contributions to the work of nurse clinicians, nurse researchers, nurse educators, and nurse theorists. PMID- 29595528 TI - Effect of Methylprednisolone on Pain Management in Total Knee or Hip Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND: Total joint arthroplasty (TJA) has been reported to be a successful strategy for patients with advanced osteoarthritis; however, early postoperative pain has become an unresolved issue. Perioperative methylprednisolone (MP) administration in TJA is an important and controversial topic. This study was conducted to assess the efficacy and safety of MP for pain management after total knee or hip arthroplasty (TKA/THA). MATERIALS AND METHODS: PubMed, Embase, and the Cochrane Library were searched for randomized controlled trials comparing MP versus placebo for patients undergoing TKA/THA. Related indicators that reflected the efficacy and safety for pain management were evaluated by meta-analysis. RESULTS: Six randomized controlled trials involving a total of 350 patients met the inclusion criteria. The outcomes showed that intravenous MP significantly reduced pain scores at 6 and 24 hours during activity after TKA and THA but local use of MP had no clear benefit in reducing pain scores compared with the control group. There was no significant difference in VAS at 24 hours at rest and 48 hours during activity after TKA and THA. In addition, MP was associated with a reduction of morphine consumption at 24 hours after TKA. Furthermore, patients receiving MP had an obvious inflammatory control and improving postoperative nausea and vomiting and the use of MP was not associated with a significant increase in the risk of complications. There was no significant difference in the range of knee motion and length of hospital stay in both groups. CONCLUSIONS: This study showed that intravenous MP significantly alleviated early postoperative pain and the incidence of postoperative nausea and vomiting after TKA and THA. For safety, intravenous MP as a promising strategy in rapid recovery to TJA. PMID- 29595529 TI - EC50 of Epidural Ropivacaine Combined With Dexmedetomidine for Labor Analgesia. AB - BACKGROUND: It has been reported that the optimal concentration of epidural dexmedetomidine for labor analgesia is 0.5 MUg/mL when combined with 0.1% ropivacaine. This study investigated the median effective concentration (EC50) of epidural ropivacaine for labor analgesia when combined with 0.5 MUg/mL dexmedetomidine. MATERIALS AND METHODS: Sixty full-term primiparas were enrolled and divided into 2 groups in this prospective study. Group D received 10 mL solution (ropivacaine+0.5 MUg/mL dexmedetomidine) in the induction of epidural anesthesia, and group C (control group) received 10 mL of ropivacaine alone. The dose of epidural ropivacaine was decided by using the up-and-down sequential allocation method with an initial concentration of 0.1%*0.01% gradient. Effective analgesia was defined as the visual analogue scale for pain as <=3 within 30 minutes after epidural injection when cervical dilation is about 2 cm. The EC50 of ropivacaine was calculated by the Massey formula. Hemodynamic parameters, the stages of labor, and fetal heart rate were recorded. Neonatal Apgar scores and umbilical artery pH were also recorded. The side effects, if any, were noted. RESULTS: The EC50 of ropivacaine was 0.062% (95% confidence interval [CI], 0.058% 0.066%) in the group D, and 0.083% (95% CI, 0.077%-0.089%) in the group C, there was a significant difference between the groups (P<0.05). CONCLUSIONS: The EC50 of epidural ropivacaine for labor analgesia was 0.083% (95% CI, 0.077%-0.089%) and decreased to 0.062% (95% CI, 0.058%-0.066%) when combined with 0.5 MUg/mL dexmedetomidine (http://www.chictr.org.cn, registration number: ChiCTR-OPC 16008548).

PMID- 29595531 TI - Sedative and Analgesic Drug Sequestration After a Single Bolus Injection in an Ex Vivo Extracorporeal Membrane Oxygenation Infant Circuit. AB - Patient sedation and analgesia on extracorporeal membrane oxygenation (ECMO) is vital for safety and comfort. However, adsorption to the circuit may alter drug pharmacokinetics and remains poorly characterized. This study characterizes drug adsorption of morphine, fentanyl, midazolam, and dexmedetomidine in an ex vivo infant ECMO circuit utilizing polymethylpentene (PMP) membrane oxygenator (MO) with protein-bounded polyvinylchloride (PVC) tubing. Twelve closed-loop ex vivo ECMO circuits were prepared using P.h.i.s.i.o (phosphorylcholine)-coated PVC tubing (Sorin Group USA, Inc.) and a Quadrox-iD pediatric polymethylpentene MO (Maquet Cardiopulmonary AG). Once the circuits were primed and running, a single medication was injected as a bolus into the circuit with three circuits per drug. Drug samples were drawn following injection, at 2, 5, 15, 30, 60, 120 minutes and at 4, 12, 24, 36, and 48 hours and analyzed using ultra high-performance liquid chromatography with mass spectrometry. Compared with morphine, the other drugs are highly sequestered with fentanyl 68.5%, dexmedetomidine 50.8%, and midazolam 26.2% affecting the availability of free drug in the circuit. Sequestration of fentanyl, midazolam, and dexmedetomidine in an ECMO circuit with Phisio-coated PVC tubing and PMP MO may limit drug delivery to infants. Future in vivo studies are needed to determine the clinical impact of sequestration. PMID- 29595532 TI - Development of an Ex-Situ Limb Perfusion System for a Rodent Model. AB - Ex-situ perfusion (ESP) is a promising method in preserving vascularized composite tissue allografts (VCAs) with potential to widen donor procurement to larger geographic areas. To optimize the method of preservation, we developed a small animal model to conduct biomolecular investigations. Twenty rat hind limbs (18.2 +/- 1.3 g) were procured and connected to our custom-made ESP system. Perfusion pressure and flow parameters were measured with hourly blood gas analysis under near-normothermic (30-35C) conditions. Perfusate was prepared with swine hemoglobin (6-9 g/dL) and STEEN Solution. After 6 hours of perfusion, gastrocnemius muscles were evaluated for their histology and metabolomic profiling. Following 3 sets of experiments, perfusion was maintained at an average flow of 0.9 +/- 0.24 mL/min and resulted in lactate levels of 3.78 +/- 1.02 mmol/L. Metabolomic analysis revealed maintained cellular energy stores (total adenylates perfusion 0.698 +/- 0.052 versus baseline 0.685 +/- 0.091 umols/ug, p = 0.831), and histologic analysis revealed no evidence of barotrauma or myodegeneration. Rat hind limbs were viable after 6 hours of ESP on our miniaturized ESP system. This study is the first to document the ex-situ hind limb perfusion platform on a rodent model. These experimental findings have potential to guide future research to extend the viable duration of VCA preservation. PMID- 29595533 TI - IDO1 Expression Is Associated With Immune Tolerance and Poor Prognosis in Patients With Surgically Resected Esophageal Cancer. AB - OBJECTIVES: To evaluate the relationship between indoleamine 2, 3-dioxygenase (IDO1) expression and tumoral immune status and clinical outcome in esophageal cancer. SUMMARY BACKGROUND DATA: IDO1 is a primary enzyme that generates immunosuppressive metabolites such as tryptophan and kynurenine. Like the PD-1/PD L1 pathway, IDO1 plays a major role in tumor immunology and is a potential immune based therapeutic target. METHODS: The expressions of IDO1, CD8 (a marker of cytotoxic T cells), FOXP3 [a marker of regulatory T cells (Treg)], and PD-L1 in 305 curatively resected esophageal cancers were evaluated by immunostaining. RESULTS: Overall survival was significantly better in the IDO1 negative cases (n = 234) than in the IDO1 positive cases (n = 71) [log-rank P = 0.0041; hazard ratio (HR): 1.75; 95% confidence interval (CI): 1.12-2.67; P = 0.015]. CD8 high expression was significantly positively correlated with overall survival (log rank P = 0.025) and low IDO1 expression (P = 0.044). The inverse correlation between CD8 and IDO1 expressions was confirmed by double immunostaining for IDO1 and CD8. Stratification based on IDO1 and CD8 expressions was also significantly associated with overall survival (log-rank P = 0.0024). In addition, the IDO1 positive group was correlated with high counts of FOXP3-positive cells (P = 0.020), but not with PD-L1 expression status (P = 0.19). CONCLUSIONS: IDO1 expression was associated with an unfavorable clinical outcome in esophageal cancer, supporting its role as a prognostic biomarker. Combining the IDO1 and CD8 statuses enabled further classification of the clinical outcomes of patients. PMID- 29595534 TI - Challenges in Complex Wound Management. PMID- 29595535 TI - "Jelly VAC" for Negative-Pressure Therapy for Complex Wound Closure: A Report of Two Cases. AB - CASE: A 35-year-old man sustained an open calcaneal fracture with bone loss, and a 57-year-old woman sustained an avulsion of the entirety of the plantar skin. Both patients were treated with multiple debridements and soft-tissue coverage. "Jelly-VAC" (vacuum-assisted closure) therapy was used after each debridement and during the soft-tissue coverage. CONCLUSION: Jelly-VAC therapy is a promising alternative that allows negative-pressure therapy with the use of ultrasound jelly to prevent air leakage into the wound. We propose using this technique in areas where obtaining a seal is difficult, where VAC therapy is contraindicated because of adhesive dressings (i.e., with damaged or poor-quality skin), or when long-term VAC therapy is needed to prevent wound maceration or there is a need for "VAC holidays." PMID- 29595536 TI - The Masquelet Technique for Thumb Metacarpal Reconstruction Following Trauma: A Case Report. AB - CASE: We describe an unusual case of an isolated close-range shotgun injury to the thumb with substantial osseous loss and intact vascularity, followed by treatment with the Masquelet technique and iliac crest tricortical bone autograft reconstruction. CONCLUSION: Gunshot injuries to the thumb with concomitant soft tissue and osseous loss are devastating. Reconstruction depends on the level of the injury, the severity of the soft-tissue and osseous damage, and the viability of the digit, as well as patient factors, including occupation, physical demands, and expectations. PMID- 29595538 TI - Labral Augmentation with Native Tissue Preservation with a 7.5-Year Follow-up: A Case Report. AB - CASE: Arthroscopic labral repair has resulted in excellent functional outcomes. However, extensive labral damage or diminutive size of the labrum may preclude a repair. In these cases, labral augmentation serves as an operative treatment option. We report the case of a labral augmentation with 7.5 years of follow-up, including intraoperative reexamination, which highlights the ability of an iliotibial band autograft to incorporate with the native labrum. CONCLUSION: When indicated in an appropriate patient, labral augmentation with an iliotibial band autograft is an established technique that can result in an excellent outcome. PMID- 29595537 TI - Chronic Osteomyelitis Caused by Haemophilus parainfluenzae: A Case Report. AB - CASE: A 14-year-old boy presented with a pathologic fracture of the distal aspect of the tibia and a remote history of a dog bite near the injury site. Imaging studies, biopsy, and presentation corroborated the diagnosis of chronic osteomyelitis. Multiple diagnostic methods were negative until an open biopsy identified Haemophilus parainfluenzae, a fastidious oropharyngeal bacterium, with polymerase chain reaction analysis. The patient underwent extensive debridement, placement of external fixation, and a year-long antibiotic therapy regimen. He subsequently required a tibial-fibular osteotomy at a second site with placement of an intramedullary nail for correction of a leg-length discrepancy. CONCLUSION: This case report illustrates the complex management of chronic osteomyelitis in pediatric patients, its sequelae, and the importance of considering treatment of atypical pathogens. PMID- 29595539 TI - Repeated forced-swimming test in intact female rats: behaviour, oestrous cycle and enriched environment. AB - Psychopharmacology used animal models to study the effects of drugs on brain and behaviour. The repeated forced-swimming test (rFST), which is used to assess the gradual effects of antidepressants on rat behaviour, was standardized only in males. Because of the known sex differences in rats, experimental conditions standardized for males may not apply to female rats. Therefore, the present work aimed to standardize experimental and housing conditions for the rFST in female rats. Young or adult Wistar female rats were housed in standard or enriched environments for different experimental periods. As assessed in tested and nontested females, all rats had reached sexual maturity by the time behavioural testing occurred. The rFST consisted of a 15-min session of forced swimming (pretest), followed by 5-min sessions at 1 (test), 7 (retest 1) and 14 days (retest 2) later. The oestrous cycle was registered immediately before every behavioural session. All sessions were videotaped for further analysis. The immobility time of female rats remained similar over the different sessions of rFST independent of the age, the phase of the oestrous cycle or the housing conditions. These data indicate that rFST in female Wistar rats may be reproducible in different experimental conditions. PMID- 29595540 TI - Sex-specific differences in cannabinoid-induced extracellular-signal-regulated kinase phosphorylation in the cingulate cortex, prefrontal cortex, and nucleus accumbens of Lister Hooded rats. AB - Sex-dependent differences have been consistently described in cannabinoid addiction research. In particular, we recently reported that female Lister Hooded rats display greater self-administration of the cannabinoid CB1 receptor agonist WIN55,212-2 (WIN) and stronger reinstatement of cannabinoid-seeking behavior than males. Cannabinoids modulate the phosphorylation of the extracellular-signal regulated kinase (ERK) pathway, leading to various forms of plasticity-related learning that likely affect operant behavior. However, whether or not the reported sex-dependent differences in cannabinoid-taking and cannabinoid-seeking behaviors may be related to a sexual dimorphic activation of the ERK pathway remains still to be determined. In the present study, we measured the level of phosphoERK-positive cells in the cingulate cortex (CG1), prefrontal cortex (PFCx), and nucleus accumbens of male and of intact (i.e. sham-operated) and ovariectomized female Lister Hooded rats 30 and 60 min after an acute, intravenous, injection of a dose of WIN (0.3 mg/kg) resembling the mean amount of drug daily self-administered by trained rats. We found that WIN significantly increased ERK activation in the CG1, PFCx, and nucleus accumbens in a sex time and, restricted to the cortical areas, layer-specific manner. Moreover, the comparison between intact and ovariectomized female rats revealed a significant role played by estrogens in WIN-elicited ERK activation. These results indicate, for the first time, the existence of a sexually dimorphic cannabinoid receptor dependent ERK activation that, restricted to the CG1 and PFCx, is ovarian hormone dependent. PMID- 29595541 TI - Co-administration of amphetamine with alcohol results in decreased alcohol withdrawal severity in adolescent rats. AB - Simultaneous use of stimulants and alcohol is a growing problem, particularly among older adolescents already prone to binge alcohol consumption. Adolescent rats consume high levels of alcohol when administered in a liquid diet and develop a strong alcohol withdrawal syndrome. We exploited this system to administer amphetamine in combination with alcohol and to test the effect of co administration of amphetamine on alcohol withdrawal-induced hypoactivity and overall withdrawal severity. The presence of dietary amphetamine (<=40 mg/l) had no effect on consumption of control or alcohol-containing diets. Measured in an activity chamber, alcohol withdrawal hypoactivity was reduced significantly by co administration of amphetamine with alcohol. Overall withdrawal severity was also reduced significantly when rats consumed amphetamine with alcohol. The results suggest that amphetamine co-use may mask physical signs of alcohol dependency and add to the importance of educational strategies pointing out the potential problems associated with co-use of stimulants and alcohol. PMID- 29595542 TI - Effects of daily morphine treatment on impulsivity in rats responding under an adjusting stop-signal reaction time task. AB - Opioids can enhance delay discounting and premature responding under attentional tasks that might reflect increased impulsivity; although it is not clear whether repeated opioid administration alters behavioral inhibition. Effects of morphine and amphetamine were determined before, during, and after daily morphine administration in rats responding under a stop-signal reaction time task, measuring behavioral inhibition and motor impulsivity. Rats (n=5) completed a two response sequence to earn food. Occasionally, a tone (stop signal) was presented signifying that food would only be presented if the second response was withheld. Responding after the stop signal measured inhibition, and responding before the start of the trial (premature) measured motor impulsivity. Before daily treatment, morphine (0.32-17.8 mg/kg, intraperitoneally) decreased premature responding but did not increase responding on stop trials, whereas amphetamine (0.1-3.2 mg/kg, intraperitoneally) increased premature responding. Daily morphine administration (3.2 mg/kg/day) enhanced its effects on premature responding but did not impact other effects. Daily morphine treatment diminished the effects of amphetamine on premature and timeout responding. Repeated morphine treatment increased motor impulsivity but did not enhance behavioral inhibition. These data add to studies elucidating the relationship between impulsivity and opioid treatment and suggest that opioids differentially impact impulsive behaviors. PMID- 29595543 TI - Protective Effect of Scopoletin Against Cerulein-Induced Acute Pancreatitis and Associated Lung Injury in Mice. AB - OBJECTIVE: The present study aimed to evaluate the protective effects of scopoletin (SC) on cerulein-induced acute pancreatitis (AP) and associated lung injury in mice. METHODS: Acute pancreatitis was induced in male Swiss mice by 6 consecutive hourly intraperitoneal injections of cerulein (50 MUg/kg). Scopoletin was administered 1 hour (intraperitoneal, 10 mg/kg) after the first cerulein injection. RESULTS: Administration of SC attenuated the severity of AP and associated lung injury as shown by histology, reduced myeloperoxidase, and serum amylase activity. Further, the anti-inflammatory effect of SC was associated with a reduction of pancreatic and pulmonary proinflammatory cytokines (interleukin 1beta and tumor necrosis factor alpha) and hydrogen sulfide. Moreover, SC inhibited cerulein-induced nuclear factor kappaB activation in both pancreas and lung. Also, SC treatment further enhances the beneficial effect by reducing cerulein-induced mast cell activation as shown by reduced monocyte chemoattractant protein 1, interleukin 33, and preprotachykinin A expression (encodes neuropeptide substance P) in the pancreas and lungs. CONCLUSIONS: The present findings show for the first time that in AP SC may exhibit an anti inflammatory effect by down-regulating substance P and hydrogen sulfide signaling via nuclear factor kappaB pathway.

PMID- 29595544 TI - Luteolin Ameliorates Experimental Chronic Pancreatitis Induced by Trinitrobenzenesulfonic Acid in Rats. AB - OBJECTIVES: The purpose of this study is to assess the effect and possible mechanism of luteolin on chronic pancreatitis (CP). METHODS: Trinitrobenzenesulfonic acid-induced CP was used as CP models in vivo. After the intervention of luteolin for 28 days, chronic pancreatic injury was assessed by serum hydroxyproline and pancreatic histology. alpha-Smooth muscle actin (alpha SMA) expression was performed to detect the activation of pancreatic stellate cells (PSCs). Pancreatic stellate cells were also isolated and cultured in vitro, and the effect of luteolin on PSCs was evaluated. Transforming growth factor beta (TGF-beta1) signaling and its regulated mRNA expression was tested by Western blot and quantitative real-time polymerase chain reaction, respectively. RESULTS: The protective role of luteolin on CP was confirmed by increased pancreas/body weight ratio, decreased pancreas hydroxyproline level, and reduced fibrosis. alpha-SMA expressions in PSCs were significantly decreased both in vitro and in vivo after the management of luteolin. Pancreas TGF-beta1 expression was significantly decreased by luteolin. Luteolin inhibited the proliferation and activation of PSCs in a dose-dependent manner. CONCLUSIONS: Luteolin played a protective role in CP in many aspects, partly by regulating release of inflammatory cytokines through TGF-beta1 signaling pathway. PMID- 29595549 TI - Fathers' Stress in the Neonatal Intensive Care Unit: A Systematic Review. AB - BACKGROUND: Admission to the neonatal intensive care unit (NICU) is stressful for parents. Nurses often focus on maternal well-being and fail to acknowledge the stress of fathers. Research on fathers' psychological stress is limited. PURPOSE: A systematic review of the literature was completed to examine the extent of psychological stress and types of stressors in fathers with infants admitted to the NICU. METHODS/SEARCH STRATEGY: A search of Ovid MEDLINE, Cochrane Library, PsycINFO, CINAHL, and EMBASE was conducted to identify descriptive and observational studies reporting father-specific stress in the NICU. Studies using observational and descriptive designs, published in English, and reporting father specific stress outcomes during a NICU admission were eligible for inclusion. Strengthening the Reporting of Observational Studies in Epidemiology guidelines were used for quality assessment. RESULTS: Fifteen studies met inclusion criteria. Fathers find the NICU environment stressful and are more stressed than fathers of full-term, healthy infants. Parental role alteration, infant appearance, NICU environment, and staff communication are stressors. IMPLICATIONS FOR PRACTICE/RESEARCH: By recognizing the extent and types of psychological stress in fathers, nurses can provide better support for fathers in their new role. Younger fathers and those with very low birth-weight premature infants may need additional support and resources. Future research on fathers' stress should include larger sample sizes, diverse populations, and tool development and evaluation. PMID- 29595550 TI - Changing Neonatal Nurses' Perceptions of Caring for Infants Experiencing Neonatal Abstinence Syndrome and Their Mothers: An Evidenced-Based Practice Opportunity. AB - BACKGROUND: Neonatal intensive care units (NICUs) are caring for an increasing number of infants born with neonatal abstinence syndrome (NAS). The literature identifies the need for education for NICU nurses on NAS including skills for interacting with the mother with substance use disorder. PURPOSE: An evidence based practice project was developed to offer an educational presentation targeting these topics to 206 NICU participants (93% registered nurses, 1% licensed vocational nurses, and 6% nursing assistants) at a level IV NICU. METHODS: A pretest/posttest was developed to assess knowledge of the participants prior to and after completion of the educational presentation. A posteducational questionnaire was developed to evaluate the skills learned for interacting with the mother with substance use disorder and the participant's professional readiness. RESULTS: The posttest demonstrated a statistically significant (P < .001) increase in knowledge of NAS. On the post-educational questionnaire, 96% of participants correctly identified 3 skills they would use clinically with mothers with substance use disorder and 84% of participants identified 2 personal strengths and 2 weaknesses that influence their care of infants with NAS and their families (professional readiness). IMPLICATIONS FOR PRACTICE: These results demonstrate that this educational presentation was effective and should be replicated at other facilities to improve the knowledge and skills of NICU nurses to promote improved care for infants with NAS. IMPLICATIONS FOR RESEARCH: Future studies should examine the impact on patient outcomes by preforming post discharge interviews with the mothers of infants with NAS in the NICU pre- and post-educational intervention. Expanding the presentation into an interprofessional educational opportunity would promote increased knowledge and care by the entire multidisciplinary team.

PMID- 29595551 TI - Exploring Parent Experience of Communication About Therapeutic Hypothermia in the Neonatal Intensive Care Unit. AB - BACKGROUND: The unique communication challenges faced by parents of infants undergoing therapeutic hypothermia have not been well characterized. PURPOSE: To develop awareness of communication challenges experienced by families of infants treated with therapeutic hypothermia. METHODS: Semistructured interviews were conducted in a group setting with parents matched into groups according to the severity of the infant's presenting encephalopathy. The interviews were transcribed and coded into principal and additional subthemes. RESULTS: Thirty adults were interviewed including 15 mothers, 12 fathers, 2 grandmothers, and 1 grandfather. The 15 infants were between 2 and 24 months of age at the time of the interviews. The principal theme of communication included the following 3 subthemes; transparency, consistency, and delivery style. Parents reported a strong desire for improved early and transparent communication about therapeutic hypothermia, particularly during transfer from an outside hospital. Parents also reported a preference for consistent communication and highlighted parental touch of the hypothermic infant, obstetrical nurse-to-neonatal intensive care unit nurse communication, and parent and visitor presence in the infant's room as areas in need of greater communication consistency. Parents valued direct and compassionate communication styles that excluded medical jargon. IMPLICATIONS FOR PRACTICE: All providers can implement recommendations for communication to parents of infants treated with therapeutic hypothermia by increasing transparency, developing greater consistency in the communication delivered, and employing a direct and compassionate style to improve the parental experience of therapeutic hypothermia. IMPLICATIONS FOR RESEARCH: Further investigation is needed into the specific challenges parents face with a lack of transparent communication prior to the transfer of an infant for therapeutic hypothermia. PMID- 29595553 TI - Finding My Way: A Phenomenology of Fathering in the NICU. AB - BACKGROUND: Historically, the relationship between infant and mother in the neonatal intensive care unit (NICU) has been the main focus of parenting research, leaving a gap in the literature regarding the paternal experience. PURPOSE: The purpose of this study was to gain an understanding of the lived experience of fathering an infant born at less than 28 weeks' gestation admitted to a level III NICU. METHODS: Seven fathers of premature infants (25-27 weeks' gestation) participated in a semistructured interview about the experience of becoming a father to a premature infant at least 1 to 2 weeks after the NICU admission. Data were collected in 2015. FINDINGS: The primary themes identified were looking in, persevering, holding, and finding my way. Fathers in this study described feeling like an outsider in the NICU while learning to trust strangers, protect the mother and the child, and continue to work and provide for the family. Holding for the first time is pivotal in this journey, as the moment of solidifying the connection with the child. IMPLICATIONS FOR PRACTICE: The findings from this study bring awareness of the experiences of fathers during the NICU journey of having a premature infant. Nurses should encourage paternal participation and involvement, visitation, and facilitate kangaroo care opportunities early and often. IMPLICATIONS FOR RESEARCH: The findings from this study allow nurses to better understand the paternal experience of having a premature infant born at less than 28 weeks. However, future research should continue to investigate the paternal experience with other gestational ages as well as the influence of stress of fathers during this experience. PMID- 29595554 TI - Fathers' Stress in the Neonatal Intensive Care Unit: A Systematic Review. PMID- 29595556 TI - Histopathology of Exfoliation Syndrome. AB - Exfoliation syndrome (XFS) is characterized by light and electron microscopy by age-dependent gradual accumulation of whitish material of largely unknown composition and origin along both the anterior and posterior chambers and widely within the iris stroma. These deposits can be fairly specifically labeled with selected antibodies and lectins. Immunohistochemistry shows that intraocular exfoliation deposits share antigens with the microfibrillar elastic fiber system and several basement membrane components, including carbohydrate epitopes on glycosaminoglycans, proteoglycans, and cell adhesion molecules. The earliest histopathologic manifestation of XFS seems to be the deposition of characteristic fibers in various extraocular and anterior segment tissues, as observed by electron microscopy, and perivascular deposition of material within the iris stroma, which is antigenically typical of that found in classic intraocular exfoliation deposits. These findings precede the clinical diagnosis of XFS and likewise can be detected in the seemingly uninvolved fellow eyes of patients with clinically unilateral XFS. Indeed, histopathologic examination of capsulotomy, iridectomy, and trabeculectomy specimens can lead to a clinically unexpected diagnosis of XFS. Exfoliation fibers are additionally found widely distributed in extraocular connective tissues and visceral organs, but the matrix of these fibers seems to differ from that of intraocular deposits. In addition to this histopathologic discrepancy, both the frequent occurrence of clinically unilateral, histopathologically highly asymmetric exfoliation deposits, and the relationship between the early iris vasculopathy that not infrequently may be observed histopathologically for years before classic widespread exfoliation deposits appear along the anterior and posterior chambers remain to be resolved. PMID- 29595555 TI - Mindfulness-Based Neurodevelopmental Care: Impact on NICU Parent Stress and Infant Length of Stay; A Randomized Controlled Pilot Study. AB - BACKGROUND/PURPOSE: Experiences of premature birth and neonatal intensive care unit (NICU) hospitalizations result in stress and family separation that have far reaching implications. Prior studies of neonatal neurodevelopmental care show improved infant outcomes. Previous studies of mindfulness show improved stress and health outcomes in varied disease processes. No neonatal studies of parent training in mindfulness-based neurodevelopmental care exist. This study examines the impact of parent education and participation in mindfulness-based neurodevelopmental care on parent outcomes (stress, bonding, and satisfaction) and infant length of stay (LOS). METHODS: This randomized controlled trial pilot study utilized a convenience sample of 55 parent-infant dyads. Parametric and nonparametric statistical tests examined differences in and between study groups in demographics and dependent study variables (stress, bonding, satisfaction, and LOS). RESULTS: No statistically significant differences in parent outcomes were seen between groups. However, experimental group (EG) parents showed a significant reduction in stress scores from enrollment to discharge (P = .012) and EG infants had significantly shorter LOS (P = .026-.047) than control. IMPLICATIONS FOR PRACTICE AND RESEARCH: While further research to confirm study results is warranted, changes in current NICU practices to incorporate additional parent education in mindfulness-based neurodevelopmental care may help alleviate parent stress and decrease LOS that impact financial, physical, and psychosocial outcomes for patients, families, healthcare systems, and society.

AB - PURPOSE: The purpose of this study was to determine if glaucoma filtering blebs migrate over or under the cornea epithelium using histopathologic and immunohistochemical techniques to evaluate the likely origin of the surface epithelium and bleb matrix. METHODS: Histologic and immunohistochemical evaluations were performed of normal conjunctiva (n=4), corneal overhanging dissecting blebs (n=4), and leaking blebs over the scleral surface (n=6). Antibodies were used against epithelial [cytokeratin 3 (CK3)+12, CK13] and extracellular matrix [decorin and keratan sulfate (KS)] antigens. Labeling was graded in a semiquantitative manner. RESULT: The epithelium of dissecting (over cornea) blebs was labeled primarily with CK3+12 antibody. KS staining was faint and comparable in normal conjunctiva, and the stroma of dissecting and leaking blebs (P=0.12). Decorin staining in the normal conjunctival stroma was of moderate intensity and comparable with the dissecting bleb staining and; significantly greater than that in the leaking blebs (P=0.02). CONCLUSIONS: Histology and ICH indicate that the epithelium of the dissecting blebs has a corneal epithelial phenotype. The extracellular matrix immunophenotype was similar to the normal conjunctival stroma suggesting that dissecting blebs migrate under the corneal epithelium. PMID- 29595560 TI - SPIRONOLACTONE AS A THERAPEUTIC ALTERNATIVE FOR THE BULLOUS VARIANT OF CENTRAL SEROUS CHORIORETINOPATHY. AB - PURPOSE: To report a case of the bullous variant of central serous chorioretinopathy successfully treated with spironolactone, a mineralocorticoid receptor antagonist. METHODS: Case report of a patient including fluorescein angiography, optical coherence tomography, and color fundus photography. RESULTS: Initially managed as a multifocal choroiditis, the use of oral and peribulbar corticoids worsened the serous retinal detachment. Taking in consideration this response, she was then diagnosed with a bullous variant of central serous chorioretinopathy and treated with 50 mg of spironolactone per day. Resolution of the serous retinal detachment, decrease in choroidal thickness on optical coherence tomography, and absence of leaks in fluorescein angiography was achieved 2 months posterior to the first dose of oral spironolactone. CONCLUSION: We suggest the use of mineralocorticoid receptor antagonists, such as spironolactone, as a therapeutic alternative to more aggressive available treatments for the bullous variant of central serous chorioretinopathy. PMID- 29595559 TI - MTHFR gene methylation is associated with perceived stress in healthy young adults. AB - BACKGROUND: Epigenetic factors have been identified in the past years as interesting candidates for psychiatric disorders and related endophenotypes. It has been found that the methylenetetrahydrofolate reductase (MTHFR) gene is associated with major depressive disorder, and the aim of the current study was to examine the possible association between perceived stress and MTHFR methylation, taking into account depressive symptoms as a covariate. PARTICIPANTS AND METHODS: Seventy-eight healthy Colombian participants (mean age=20.9 years; SD=3.0) were evaluated with the Perceived Stress Scale and with the Patient Health Questionnaire-9 for depressive symptomatology. MTHFR methylation levels were measured with a methylation-sensitive high-resolution melting method. A multiple regression analysis (adjusting for age, sex, and depressive symptoms) was carried out to assess the association between MTHFR methylation and perceived stress scores. RESULTS: We found a significant inverse correlation between MTHFR methylation levels and perceived stress scores (r=-0.502; P=5.9*10(-5)), which remained significant after being adjusted for age, sex, and depressive symptomatology. CONCLUSION: To our knowledge, this is the first study that reports an association between perceived stress and MTHFR methylation levels. This report adds evidence to the emerging role of epigenetic changes in endophenotypes related to affective disorders. PMID- 29595561 TI - Dynamics of Endotoxin, Inflammatory Variables, and Organ Dysfunction After Treatment With Antibiotics in an Escherichia coli Porcine Intensive Care Sepsis Model. AB - OBJECTIVES: To investigate the dynamics of antibiotic-induced endotoxin liberation and inflammatory response in vivo in a clinically relevant large animal intensive care sepsis model and whether the addition of an aminoglycoside to a beta-lactam antibiotic affects these responses. DESIGN: Prospective, placebo controlled interventional experimental study. SETTING: University research unit. SUBJECTS: Thirty-six healthy pigs administered Escherichia coli as a 3-hour infusion. INTERVENTIONS: After 2 hours, during E. coli infusion, the animals were exposed to cefuroxime alone, the combination of cefuroxime and tobramycin, or saline. MEASUREMENTS AND MAIN RESULTS: Plasma endotoxin, interleukin-6, tumor necrosis factor-alpha, leucocytes, and organ dysfunction were recorded for 4 hours after antibiotic treatment, and differences to the values before treatment were calculated. In vitro experiments were performed to ascertain whether endotoxin is released during antibiotic-induced bacterial killing of this E. coli strain. Despite differences between the treatment arms in vitro, no differences in plasma endotoxin were observed in vivo. Antibiotic-treated animals demonstrated a higher interleukin-6 response (p < 0.001), greater leucocyte activation (p < 0.001), and more pronounced deterioration in pulmonary static compliance (p < 0.01) over time than controls. Animals treated with the combination showed a trend toward less inflammation. CONCLUSIONS: Treatment with antibiotics may elicit an increased inflammatory interleukin-6 response that is associated with leucocyte activation and pulmonary organ dysfunction. No observable differences were detected in plasma endotoxin concentrations. The reduction in cefuroxime-induced endotoxin release after the addition of an aminoglycoside in vitro could not be reproduced in this model. PMID- 29595562 TI - Effect of Administration of Ramelteon, a Melatonin Receptor Agonist, on the Duration of Stay in the ICU: A Single-Center Randomized Placebo-Controlled Trial. AB - OBJECTIVES: Occurrence of delirium in the ICU is associated with a longer stay in the ICU. To examine whether the use of ramelteon, a melatonin agonist, can prevent delirium and shorten the duration of ICU stay of critically ill patients. DESIGN: A single-center, triple-blinded, randomized placebo-controlled trial. SETTING: ICU of an academic hospital. PATIENTS: Eligible patients were ICU patients who could take medicines orally or through a nasogastric tube during the first 48 hours of admission. INTERVENTIONS: The intervention group received ramelteon (8 mg/d), and the control group received placebo (1 g/d of lactose powder) at 20:00 hours every day until discharge from the ICU. MEASUREMENTS AND MAIN RESULTS: A total of 88 subjects were randomized to the ramelteon group (45 subjects) or the placebo group (43 subjects). As the primary endpoint, there was a trend toward decrease in the duration of ICU stay (4.56 d) in the ramelteon group compared with the placebo group (5.86 d) (p = 0.082 and p = 0.028 before and after adjustments). As the secondary endpoints, statistically significant decreases in the occurrence rate (24.4% vs 46.5%; p = 0.044) and duration (0.78 vs 1.40 d; p = 0.048) of delirium were observed in the ramelteon group. The nonintubated patients of the ramelteon group showed statistically significantly fewer awakenings per night and a higher proportion of nights without awakenings. CONCLUSIONS: Ramelteon tended to decrease the duration of ICU stay as well as decreased the occurrence rate and duration of delirium statistically significantly.

PMID- 29595563 TI - One-Year Outcomes in Patients With Acute Respiratory Distress Syndrome Enrolled in a Randomized Clinical Trial of Helmet Versus Facemask Noninvasive Ventilation. AB - OBJECTIVES: Many survivors of acute respiratory distress syndrome have poor long term outcomes possibly due to supportive care practices during "invasive" mechanical ventilation. Helmet noninvasive ventilation in acute respiratory distress syndrome may reduce intubation rates; however, it is unknown if avoiding intubation with helmet noninvasive ventilation alters the consequences of surviving acute respiratory distress syndrome. DESIGN: Long-term follow-up data from a previously published randomized controlled trial. PATIENTS: Adults patients with acute respiratory distress syndrome enrolled in a previously published clinical trial. SETTING: Adult ICU. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was functional independence at 1 year after hospital discharge defined as independence in activities of daily living and ambulation. At 1 year, patients were surveyed to assess for functional independence, survival, and number of institution-free days, defined as days alive spent living at home. The presence of ICU-acquired weakness and functional independence was also assessed by a blinded therapist on hospital discharge. On hospital discharge, there was a greater prevalence of ICU-acquired weakness (79.5% vs 38.6%; p = 0.0002) and less functional independence (15.4% vs 50%; p = 0.001) in the facemask group. One-year follow-up data were collected for 81 of 83 patients (97.6%). One-year mortality was higher in the facemask group (69.2% vs 43.2%; p = 0.017). At 1 year, patients in the helmet group were more likely to be functionally independent (40.9% vs 15.4%; p = 0.015) and had more institution free days (median, 268.5 [0-354] vs 0 [0-323]; p = 0.017). CONCLUSIONS: Poor functional recovery after invasive mechanical ventilation for acute respiratory distress syndrome is common. Helmet noninvasive ventilation may be the first intervention that mitigates the long-term complications that plague survivors of acute respiratory distress syndrome managed with noninvasive ventilation. PMID- 29595565 TI - Factors Influencing Part-time Faculty Engagement With Online Nursing Programs. AB - This research investigated factors that influenced the engagement of part-time faculty teaching in online nursing programs with their institutions. Of the 257 part-time faculty surveyed, the most significant factor was being supported in decisions regarding student issues, followed by institutional commitment to quality online education. Compensation was moderately influential; a negative factor was requiring too frequent meetings. Understanding factors that influence the engagement of part-time faculty teaching in online nursing programs can help leaders of online programs attract and retain experienced, highly skilled faculty. PMID- 29595566 TI - Student Perceptions of Peer Evaluation in an Online RN-to-BSN Course. AB - The purpose of this study was to explore student perceptions of peer-evaluation experiences in an online RN-to-BSN nursing research course. A total of 140 students completed the online survey. A majority of students reported their peer evaluation experience was helpful for learning (69%), and 81.8% of students indicated their writing skills improved. Findings of the study support the use of peer evaluation in online nursing courses. PMID- 29595567 TI - Integrating Climate Change Into Nursing Curricula. AB - Climate change is a significant threat to human health across the life cycle. Nurses play an important role in mitigation, adaptation, and resilience to climate change. The use of health care resources, air quality and extreme heat, mental health, and natural disasters are major content areas across undergraduate nursing curricula that influence or are influenced by climate change. Teaching strategies and resources are offered to prepare nursing students to address climate change and human health. PMID- 29595568 TI - Hotspotting: Development of an Interprofessional Education and Service Learning Program for Care Management in Home Care Patients. AB - The purpose of this article is to describe a service learning opportunity where interprofessional teams of students worked together to address patients' social determinants of health through home visits. This article describes this process, known as "hotspotting," and presents the development of this project, including collaboration with a local home health agency, recruiting of students, and weekly team meetings for debriefing. Evaluation data, barriers with implementation, and next steps for sustainability are also discussed. PMID- 29595569 TI - SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY FINDINGS AND VISUAL OUTCOME AFTER TREATMENT FOR VITREOMACULAR TRACTION. AB - PURPOSE: To evaluate the capacity of spectral domain optical coherence tomography macular findings to predict best-corrected visual acuity (BCVA) outcomes after treatment for symptomatic vitreomacular traction. METHODS: This consecutive, retrospective study included 24 patients (29 eyes) who experienced vitreomacular traction release with pneumatic vitreolysis (n = 9), intravitreal ocriplasmin (n = 6), or pars plana vitrectomy (n = 14). Preoperative and postoperative spectral domain optical coherence tomography images were used to determine the cone outer segment tips (COST) line, inner segment/outer segment line, and other frequently used features. Correlations between optical coherence tomography findings and BCVA were determined using regression analyses. RESULTS: Postoperative BCVA was correlated with length of the COST line and inner segment/outer segment line defects at 1, 3, 6, and 12 months postoperatively (P < 0.05) by simple linear regression analysis. However, multivariable regression analysis showed that only length of the COST line defect was significantly correlated with BCVA preoperatively and postoperatively (P < 0.05). Postoperative BCVA improvement at 12 months was significantly correlated with preoperative length of the COST line defect (P < 0.01). CONCLUSION: Recovery of the COST line and inner segment/outer segment line defects as observed by spectral domain optical coherence tomography is positively correlated with visual acuity improvement after successful vitreomacular traction treatment. Best-corrected visual acuity improvement may be predicted using the length of the preoperative COST line defect. PMID- 29595570 TI - Reply. PMID- 29595571 TI - Targeted ultrasound and fine-needle aspiration cytology for sentinel node diagnostics in early-stage melanoma: a validation study. AB - Ultrasound-guided fine-needle aspiration cytology (US-FNAC) is used to evaluate the involvement of lymph nodes in various malignant diseases. Its value in detecting sentinel lymph node (SN) metastasis preoperatively in melanoma patients is controversial and is the subject of this study. In this prospective validation study, 91 consecutive patients with melanoma clinical stage I (n=64) and II (n=27) were examined with US-FNAC before SN biopsy from 2012 to 2014 at a tertiary center. All patients underwent lymphoscintigraphy before the US-FNAC. Lymph nodes that showed any of the Berlin morphologic criteria on ultrasonography were examined using FNAC. The median Breslow thickness of the melanomas was 1.22 mm (range: 0.47-11.5 mm). Twenty-two percent of the patients had metastases in their SNs, 90% of which were smaller than 2 mm in largest diameter. The percentages of metastases with a size more than 1 mm were 50 and 29%, respectively, in the true-positive and false-negative US groups. The sensitivity, specificity, positive predictive value, and negative predictive value for overall US examination were 30, 81, 24, and 83%, respectively. None of the FNACs contained conclusive malignant cells. The specificity of the FNAC was 76%. Our results show that US-FNAC was not a useful diagnostic tool in our setting as it did not add significantly to the staging and management of patients with mainly thin cutaneous melanomas, perhaps because of the often small size of the SN metastases. It may be useful in the early diagnosis of lymph node metastases in a subgroup of melanoma patients with larger metastases.

PMID- 29595573 TI - Public Health Resilience Checklist for High-Consequence Infectious Diseases Informed by the Domestic Ebola Response in the United States. AB - CONTEXT: The experiences of communities that responded to confirmed cases of Ebola virus disease in the United States provide a rare opportunity for collective learning to improve resilience to future high-consequence infectious disease events. DESIGN: Key informant interviews (n = 73) were conducted between February and November 2016 with individuals who participated in Ebola virus disease planning or response in Atlanta, Georgia; Dallas, Texas; New York, New York; or Omaha, Nebraska; or had direct knowledge of response activities. Participants represented health care; local, state, and federal public health; law; local and state emergency management; academia; local and national media; individuals affected by the response; and local and state governments. Two focus groups were then conducted in New York and Dallas, and study results were vetted with an expert advisory group. RESULTS: Participants focused on a number of important areas to improve public health resilience to high-consequence infectious disease events, including governance and leadership, communication and public trust, quarantine and the law, monitoring programs, environmental decontamination, and waste management. CONCLUSIONS: Findings provided the basis for an evidence-informed checklist outlining specific actions for public health authorities to take to strengthen public health resilience to future high consequence infectious disease events. PMID- 29595574 TI - Federal Weatherization and Health Education Team up: Process Evaluation of a New Strategy to Improve Health Equity for People With Asthma and Chronic Obstructive Pulmonary Disease. AB - Unhealthy housing is a major cause of respiratory health inequity. In-home health education improves health equity for low-income and minority populations with asthma and chronic obstructive pulmonary disease. Yet, outcomes of educational interventions are limited by poor housing conditions. Federal weatherization programs represent a promising source of funding for home repairs. Innovative legislation in Washington State integrates the 2 interventions as "Weatherization Plus Health," offering environmental health education in partnership with the Weatherization Assistance Program for low-income families with respiratory disease. This practice brief describes process evaluation results of a Weatherization Plus Health program in Pierce County, Washington. Evaluation data were gathered via interviews with service providers and ethnographic observation. Workers report that the combined intervention expanded their understanding of their practice, skills, and feelings of efficacy in meeting client needs. Integrating federally funded home weatherization with health education shows promise for building public health system capacity and increasing health equity. PMID- 29595575 TI - Retrospective Evaluation of the Short-Term Sustainability of the Locally Grown Produce Initiative of the Hunger Prevention and Nutrition Assistance Program in New York State. AB - CONTEXT: The Hunger Prevention and Nutrition Assistance Program (HPNAP) is a New York State Department of Health program. The HPNAP improves nutritional quality of food available at food banks, food pantries, soup kitchens, and emergency shelters through contractual relationships to fund the purchase, delivery, storage, and service of nutritious food. OBJECTIVE: To determine whether a one time fiscal stimulus of the Locally Grown Produce Initiative to HPNAP contractors in 2012-2013 would result in a short-term sustainable increase in the proportion of dollars spent on New York State Grown (NYSG) produce. DESIGN: Quasi experimental, nonequivalent control group design. We analyzed New York State Department of Health administrative data regarding expenditures on all produce and NYSG produce by HPNAP contractors. SETTING: New York State. OUTCOME MEASURES: The proportion of dollars spent on NYSG produce during 2011-2012 (preintervention) and 2013-2014 (postintervention) was compared between HPNAP food bank contractors (recipients of stimulus money, n = 8) and non-food bank contractors (nonrecipients, n = 34) using nonparametric methods. RESULTS: The HPNAP Locally Grown Produce Initiative was associated with an increased proportion of NYSG produce spending by food bank contractors that received a fiscal stimulus 1 year later. Upstate food banks had the largest increase (median 31.6%) among all HPNAP contractors. CONCLUSION: The results of this study revealed that the Locally Grown Produce Initiative fiscal stimulus had a positive, year-long and statewide effect on the proportion of expenditure on NYSG produce by food banks. We hope that the initial success seen in New York State may encourage other states to adopt similar initiatives in future. PMID- 29595576 TI - Leadership Perceptions of Endgame Strategies for Tobacco Control in California. AB - OBJECTIVE: To explore the perspectives of key stakeholders regarding advancement of the tobacco endgame in California. DESIGN: Interviews and focus groups exploring participants' knowledge of the tobacco endgame concept, their reactions to 4 endgame policy proposals (banning tobacco sales, registering smokers, retailer reduction, and permanently prohibiting tobacco sales to all those born after a certain year ["tobacco-free generation"]), and policy priorities and obstacles. PARTICIPANTS: Interviews with 11 California legislators/legislative staff members, 6 leaders of national tobacco control organizations, and 5 leaders of California-based organizations or California subsidiaries of national organizations. Focus groups (7) with professional and volunteer tobacco control advocates in Northern, Southern, and Central California. RESULTS: Advocates were more familiar with the endgame concept than legislators or legislative staff. All proposed endgame policies received both support and opposition, but smoker registration and banning tobacco sales were the least popular, regarded as too stigmatizing or too extreme. The tobacco-free generation and retailer-reduction policies received the most support. Both were regarded as politically feasible, given their focus on protecting youth or regulating retailers and their gradual approach. Concerns raised about all the proposals included the creation of black markets and the potential for disparate impacts on disadvantaged communities. CONCLUSION: Participants' willingness to support novel tobacco control proposals suggests that they understand the magnitude of the tobacco problem and have some appetite for innovation despite concerns about specific endgame policies. A preference for more gradual approaches suggests that taking incremental steps toward an endgame policy goal may be the most effective strategy. PMID- 29595577 TI - What Is the Appropriate Role of Interprofessional Education in Public Health? PMID- 29595578 TI - A Menu to Evaluate Factors Influencing Implementation of Obesity Prevention Early Care and Education Regulations. AB - CONTEXT: In recent years, several states have adopted new regulations concerning nutrition, physical activity, and screen time in early care and education (ECE) settings to help prevent childhood obesity. OBJECTIVE: To disseminate a menu of factors that facilitate and/or impede implementation of obesity prevention regulations in ECE settings. DESIGN: To create the menu, we condensed and categorized factors identified in the literature and through field work by placing them within domains. We applied the menu by conducting semistructured interviews during a pilot test assessing implementation of ECE regulations in Colorado. SETTING AND PARTICIPANTS: We first interviewed state and local government agency leaders responsible for policy oversight, and state employees and contractors who acted as intermediaries to direct implementers. We then interviewed directors at ECE centers in the Denver, Colorado, area. We selected 21 ECE centers for a site visit on the basis of feasibility, percentage of low income families, and diversity in race and ethnicity at each center. Seven centers participated. MAIN OUTCOME MEASURES: Minor and major facilitators and impediments to implementation of childhood obesity prevention regulations in ECE settings. RESULTS: The resulting menu includes 7 domains and 39 factors influential for implementation of ECE regulations. Of these 39 factors, interviewees identified 7 facilitating factors (4 major and 3 minor) and 2 impeding factors (both major). Major facilitating factors were buy-in from parents/caregivers, training and communication provided by governing authority and their contractors, and low level of change required by the regulations themselves. Major impeding factors were timing of implementation and balancing the demands of the regulations against other priorities. CONCLUSIONS: The menu developed by our research team, combined with existing frameworks in dissemination and implementation research, can be used by researchers, practitioners, and policy makers to anticipate factors that facilitate and/or impede implementation of ECE policies to prevent childhood obesity. PMID- 29595579 TI - Prevention of Otic Barotrauma in Aviation: A Systematic Review. AB - OBJECTIVE: To conduct a systematic review of the published evidence relating to the prevention of otic barotrauma in aviation. In particular, this review sought to identify procedures, techniques, devices, and medications for the prevention of otic barotrauma as well as evaluate the evidence relating to their efficacy. DATA SOURCES: Ten databases including Embase, MEDLINE, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched using the full historical range. STUDY SELECTION: English language articles including more than or equal to five participants or cases were included. Outcomes of interest were reduced severity or the successful prevention of otic barotrauma in participants undergoing gradual changes in pressure during air travel or its simulation. DATA EXTRACTION: Articles and data were extracted and analyzed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses and other international guidelines. CONCLUSIONS: This review highlights the lack of published evidence relating to what is a significant and increasingly common problem in otology. There is level 1 evidence that supports the efficacy of oral pseudoephedrine (120 mg) in preventing otic barotrauma in adults. However, oral pseudoephedrine (1 mg/kg) does not appear to be effective in children. There is insufficient evidence to support the efficacy of either nasal balloon inflation or pressure-equalizing ear plugs for the prevention of otic barotrauma. A recently reported, novel technique for insertion of temporary tympanostomy tubes is promising but requires further evaluation.

PMID- 29595580 TI - The Use of Vibrotactile Feedback During Dual-Task Standing Balance Conditions in People With Unilateral Vestibular Hypofunction. AB - HYPOTHESIS: People with unilateral vestibular hypofunction (UVH) would have increased postural sway and slower reaction times while using vibrotactile feedback (VTF) during dual-task conditions compared with age-matched controls. BACKGROUND: VTF has been shown to improve real-time balance performance in persons with vestibular disorders. Future use of this technology outside of the laboratory environment as a real-time balance aid requires that using VTF during dual-tasking scenarios be studied. METHOD: Nine people with UVH and nine age matched controls participated in a study focused on assessing the effects of a secondary cognitive task and sensory integration conditions on the root-mean square of center of pressure (RMS COP) while using VTF. Reaction times from the secondary cognitive task were used to assess the effects of VTF, and sensory integration conditions on the attention required to perform the task. RESULTS: The results showed that there was no group difference between individuals with UVH and age-matched controls on balance performance while using VTF during dual task conditions. Using VTF significantly degraded the reaction time performance in both groups, and the participants with UVH had slower reaction times compared with controls. CONCLUSION: People with UVH showed the ability to use VTF to control balance during dual-task conditions, but more attentional resources were needed to perform the secondary cognitive tasks while using VTF.

AB - OBJECTIVE: This study examined the associations between gait variability based on common spatiotemporal parameters and energetic cost of walking in persons with multiple sclerosis. DESIGN: Eighty-six persons with multiple sclerosis underwent the 6-min walk while wearing a portable metabolic unit. The cost of walking was generated by dividing the net steady-state VO2 (milliliter per kilogram per minute) by walking speed during the 6-min walk. Participants further completed two trials of walking on the GAITRite mat at a self-selected pace for measuring spatiotemporal parameters. Variability of step length, step time, stride length, swing time, stance time, stride velocity, and single- and double-support time was indexed by the coefficient of variation. RESULTS: Variability in the spatiotemporal variables and Expanded Disability Status Scale scores were significantly correlated with cost of walking (i.e., rho = 0.25-0.36). Multivariate analysis revealed that disability (Expanded Disability Status Scale: beta = 0.186), stance time variability (beta = 1.446), and step length variability (beta = -1.216) explained significant variance (R = 0.38, P < 0.001) in cost of walking. CONCLUSIONS: We provide evidence of the positive association between gait variability and cost of walking during overground walking in persons with multiple sclerosis. The findings highlight the need for interventions aiming to reduce gait variability, thereby reducing the energetic demands of walking in this population. PMID- 29595585 TI - The Efficiency of a Multicomponent Training for Prospective Memory Among Healthy Older Adults: A Single-Blind, Randomized Controlled Within-Participants Cross Over Trial. AB - OBJECTIVE: The main objective of the present trial was to evaluate the efficiency of a preventative multicomponent prospective memory training among healthy older adults. DESIGN: This study was a two-arm within-participants trial with 4- and 12 wk follow-ups. Allocation ratio was 1:1, and pretraining and posttraining measurements were included. A total number of 25 healthy older adults were enrolled (mean = 63.32, SD = 4.44). Participants were randomly allocated into two conditions: (a) prospective memory training: participants underwent a multicomponent prospective memory training, and (b) control: participants were not contacted during the training phase. After the training phase was finished, participants crossed over to undergo the condition they did not experience before. The differences between pretraining and posttraining measures of prospective memory, activities of daily living, negative mood (depression), and anxiety were assessed. All changes in the measurements were analyzed using general linear method. This trial is registered at https://www.isrctn.com (#ISRCTN57600070). RESULTS: Multicomponent prospective memory training program was significantly effective on both subjective and objective prospective memory performances among healthy older adults. Moreover, the training had significant positive effects on activities of daily living (independence) among participants. In addition, negative mood and anxiety levels were reduced after the training was finished. CONCLUSIONS: This multicomponent prospective memory training improved prospective memory performance and activities of daily living and reduce negative mood (depression) and anxiety levels among healthy older adults. PMID- 29595584 TI - Discharge Patterns for Ischemic and Hemorrhagic Stroke Patients Going From Acute Care Hospitals to Inpatient and Skilled Nursing Rehabilitation. AB - OBJECTIVE: The aim of the study was to explore variation in acute care use of inpatient rehabilitation facilities and skilled nursing facilities rehabilitation after ischemic and hemorrhagic stroke. DESIGN: A secondary analysis of Medicare claims data linked to inpatient rehabilitation facilities and skilled nursing facilities assessment files (2013-2014) was performed. RESULTS: The sample included 122,084 stroke patients discharged to inpatient or skilled nursing facilities from 3677 acute hospitals. Of the acute hospitals, 3649 discharged patients with an ischemic stroke (range = 1-402 patients/hospital, median = 15) compared with 1832 acute hospitals that discharged patients with hemorrhagic events (range = 1-73 patients/hospital, median = 4). The intraclass correlation coefficient examined variation in discharge settings attributed to acute hospitals (ischemic intraclass correlation coefficient = 0.318, hemorrhagic intraclass correlation coefficient = 0.176). Patients older than 85 yrs and those with greater numbers of co-morbid conditions were more likely to discharge to skilled nursing facilities. Comparison of self-care and mobility across stroke type suggests that patients with ischemic stroke have higher functional abilities at admission. CONCLUSIONS: This study suggests demographic and clinical differences among stroke patients admitted for postacute rehabilitation at inpatient rehabilitation facilities and skilled nursing facilities settings. Furthermore, examination of variation in ischemic and hemorrhagic stroke discharges suggests acute facility-level differences and indicates a need for careful consideration of patient and facility factors when comparing the effectiveness of inpatient rehabilitation facilities and skilled nursing facilities rehabilitation.

AB - OBJECTIVE: To identify the quality improvement (QI) and performance management benefits reported by public health departments as a result of participating in the national, voluntary program for public health accreditation implemented by the Public Health Accreditation Board (PHAB). DESIGN: We gathered quantitative data via Web-based surveys of all applicant and accredited public health departments when they completed 3 different milestones in the PHAB accreditation process. PARTICIPANTS: Leadership from 324 unique state, local, and tribal public health departments in the United States. RESULTS: Public health departments that have achieved PHAB accreditation reported the following QI and performance management benefits: improved awareness and focus on QI efforts; increased QI training among staff; perceived increases in QI knowledge among staff; implemented new QI strategies; implemented strategies to evaluate effectiveness and quality; used information from QI processes to inform decision making; and perceived achievement of a QI culture. The reported implementation of QI strategies and use of information from QI processes to inform decision making was greater among recently accredited health departments than among health departments that had registered their intent to apply but not yet undergone the PHAB accreditation process. Respondents from health departments that had been accredited for 1 year reported higher levels of staff QI training and perceived increases in QI knowledge than those that were recently accredited. CONCLUSIONS: PHAB accreditation has stimulated QI and performance management activities within public health departments. Health departments that pursue PHAB accreditation are likely to report immediate increases in QI and performance management activities as a result of undergoing the PHAB accreditation process, and these benefits are likely to be reported at a higher level, even 1 year after the accreditation decision. PMID- 29595592 TI - Has Voluntary Public Health Accreditation Impacted Health Department Perceptions and Activities in Quality Improvement and Performance Management? AB - CONTEXT: The Public Health Accreditation Board (PHAB) is now in its 10th year, making it an ideal time to study the impact of PHAB accreditation on local health departments (LHDs). OBJECTIVE: To examine whether applying for PHAB accreditation affects perceptions and activities regarding quality improvement (QI) and performance management (PM) within LHDs. DESIGN: Data from the National Association of County & City Health Officials' 2010, 2013, and 2016 National Profile of Local Health Departments and associated QI modules were linked to PHAB applicant data collected in e-PHAB in a cross-sectional and longitudinal approach examining self-reported QI/PM activities. PARTICIPANTS: Local health departments responding to National Association of County & City Health Officials Profile questionnaires and QI modules in 2010, 2013, and 2016. MAIN OUTCOME MEASURES: Implementation of formal QI program within agency, numbers of formal QI projects in the past year, presence of elements indicating formal QI program implementation, and changes over time by accreditation status as of June 2017. RESULTS: Accredited and in-process LHDs showed greater gains over time in all of the outcome measures than LHDs not registered in e-PHAB. Results of logistic regression controlling for population served and governance type found accredited LHDs more likely to report formal QI programs agency-wide (odds ratio: [OR] = 27.0; P < .001) and have implemented 6 to 8 elements of formal QI (OR = 27.0; P < .001) in 2016, compared with nonaccreditation-seeking LHDs. Between 2013 and 2016, LHDs that responded to both survey waves that were registered in e-PHAB or accredited were significantly more likely than nonaccreditation-seeking LHDs to report any increase in overall level of QI implementation (OR = 4.89; P = .006) and increase in number of elements of formal QI (OR = 16.1; P < .001). CONCLUSIONS: Local health departments accredited by June 2017 and those in process reported more formal QI activities and showed greater improvements with QI/PM implementation over time than LHDs not undertaking accreditation. Public Health Accreditation Board accreditation appears to influence QI/PM uptake. As health departments are contemplating whether to apply for accreditation, the potential for developing a more robust QI/PM system should be taken into account.

PMID- 29595595 TI - Changes in Local Public Health System Performance Before and After Attainment of National Accreditation Standards. AB - OBJECTIVE: The aim of this study is to investigate the impact of Public Health Accreditation Board (PHAB) accreditation on the delivery of public health services and on participation from other sectors in the delivery of public health services in local public health systems. DESIGN: This study uses a longitudinal repeated measures design to identify differences between a cohort of public health systems containing PHAB-accredited local health departments and a cohort of public health systems containing unaccredited local health departments. It uses data spanning from 2006 to 2016. SETTING: This study examines a cohort of local public health systems that serves large populations and contains unaccredited and PHAB-accredited local health departments. PARTICIPANTS: Data in this study were collected from the directors of health departments that include local public health systems followed in the National Longitudinal Study of Public Health Systems. INTERVENTION: The intervention examined is PHAB accreditation. MAIN OUTCOME MEASURES: The study focuses on 4 areas: the delivery of core public health services, local health department contribution toward these services, participation in the delivery of these services by other members of the public health system, and public health system makeup. RESULTS: Prior to the advent of accreditation, public health systems containing local health departments that were later accredited by PHAB appear quite similar to their unaccredited peers. Substantial differences between the 2 cohorts appear to manifest themselves after the advent of accreditation. Specifically, the accredited cohort seems to offer a broader array of public health services, involve more partners in the delivery of those services, and enjoy a higher percentage of comprehensive public health systems. CONCLUSIONS: The results of this study suggest that accreditation may yield significant benefits and may help public health systems develop the public health system capital necessary to protect and promote the public's health. PMID- 29595596 TI - Accredited Health Department Partnerships to Improve Health: An Analysis of Community Health Assessments and Improvement Plans. AB - CONTEXT: The Public Health Accreditation Board (PHAB) Standards & Measures require the development and updating of collaborative community health assessments (CHAs) and community health improvement plans (CHIPs). OBJECTIVE: The goal of this study was to analyze the CHAs and CHIPs of PHAB-accredited health departments to identify the types of partners engaged, as well as the objectives selected to measure progress toward improving community health. DESIGN: The study team extracted and coded data from documents from 158 CHA/CHIP processes submitted as part of the accreditation process. Extracted data included population size, health department type, data sources, and types of partner organizations. Health outcome objectives were categorized by Healthy People 2020 Leading Health Indicator (LHI), as well as by the 7 broad areas in the PHAB reaccreditation framework for population health outcomes reporting. PARTICIPANTS: Participants included health departments accredited between 2013 and 2016 that submitted CHAs and CHIPs to PHAB, including 138 CHAs/CHIPs from local health departments and 20 from state health departments. RESULTS: All the CHAs/CHIPs documented collaboration with a broad array of partners, with hospitals and health care cited most frequently (99.0%). Other common partners included nonprofit service organizations, education, business, and faith-based organizations. Small health departments more frequently listed many partner types, including law enforcement and education, compared with large health departments. The majority of documents (88.6%) explicitly reference Healthy People 2020 goals, with most addressing the LHIs nutrition/obesity/physical activity and access to health services. The most common broad areas from PHAB's reaccreditation framework were preventive health care and individual behavior. CONCLUSIONS: This study demonstrates the range of partners accredited health departments engage with to collaborate on improving their communities' health as well as the objectives used to measure community health improvement. This illustrates the collaborative nature in which accredited health departments tackle community priorities.

AB - As part of accreditation, Public Health Accreditation Board site visitors recommended that the New Orleans Health Department strengthen its quality improvement program. With support from the Public Health Accreditation Board, the New Orleans Health Department subsequently embarked on a data-driven planning process through which it prioritized quality improvement projects for 2016. One of these projects aimed to improve referrals to New Orleans Health Department's direct services programs from local clinics and hospitals to better provide our most vulnerable residents with a continuum of care. After completing a cause-and effect analysis, we implemented a solution involving increased outreach to health care institutions and saw annual participation increase in 3 out of 4 of our programs. We leveraged this work to successfully apply for funding to create a centralized referral system, which will facilitate partnerships among local health and human service agencies and improve access to services. This is one example of how accreditation has benefited our health department and our community. We have found that the accreditation process promotes a culture of quality and helps health departments identify and address areas for improvement. PMID- 29595605 TI - Public Health Employees' Perception of Workplace Environment and Job Satisfaction: The Role of Local Health Departments' Engagement in Accreditation. AB - OBJECTIVES: To examine the association between local health departments' (LHDs') engagement in accreditation and their staffs' perceptions of workplace environment and the overall satisfaction with their jobs. DESIGN: Data from the 2014 Public Health Workforce Interests and Needs Survey (PH WINS) (local data only) and the 2014 Forces of Change survey were linked using LHDs' unique ID documented by the National Association of County & City Health Officials. The Forces of Change survey assessed LHDs' accreditation status. Local health departments were classified as "formally engaged" in the Public Health Accreditation Board accreditation process if they had achieved accreditation, submitted an application, or submitted a statement of intent. The PH WINS survey measured employees' perception of 3 aspects of workplace environment, including supervisory support, organizational support, and employee engagement. The overall satisfaction was measured using the Job in General Scale (abridged). There are 1884 LHD employees who completed PH WINS and whose agencies responded to the question on the accreditation status of the Forces of Change survey. RESULTS: When compared with employees from LHDs less engaged in accreditation, employees from LHDs that were formally engaged in accreditation gave higher ratings to all 3 aspects of workplace environment and overall job satisfaction. Controlling for employee demographic characteristics and LHD jurisdiction size, the agency's formal engagement in accreditation remained related to a higher score in perceived workplace environment and job satisfaction. After controlling for perceived workplace environment, accreditation status was marginally associated with job satisfaction. CONCLUSION: The findings provide support for previous reports by LHD leaders on the benefits of accreditation related to employee morale and job satisfaction. The results from this study allow us to further catalog the benefits of accreditation in workforce development and identify factors that may moderate the extent of the benefits. Findings from this study show that engagement in public health accreditation is associated with overall job satisfaction. This link may be explained by the hypotheses that meeting accreditation standards could increase staff satisfaction or that having higher job satisfaction could lead to a higher likelihood that a health department would apply for accreditation. Further research to explore this relationship is critical as many health departments are weighing the value of accreditation as they face constrained financial resources.

AB - The Florida Department of Health (Department) received accreditation status as an integrated public health system from the Public Health Accreditation Board (PHAB) in 2 phases: the State Health Office received accreditation in June 2014 and the 67 county health departments received accreditation in March 2016. Six weeks after PHAB awarded accreditation to the Department as an integrated public health system in March 2016, the World Health Organization declared the Zika outbreak in the Americas a Public Health Emergency of International Concern. Even in that short time, integrated public health accreditation, along with the other components of the Department's performance management system, allowed the Department to address this public health emergency, especially in Miami-Dade County, where the impact of Zika was significant. This case report describes the local response in Miami-Dade County and supporting statewide efforts. Public health departments should consider how public health accreditation could strengthen their ability to fulfill their public health mission. This article provides rationale for state and local health departments to seek accreditation. PMID- 29595611 TI - Kent County Health Department: Using an Agency Strategic Plan to Drive Improvement. AB - The Kent County Health Department (KCHD) was accredited by the Public Health Accreditation Board (PHAB) in September 2014. Although Michigan has had a state level accreditation process for local health departments since the late 1990s, the PHAB accreditation process presented a unique opportunity for KCHD to build on successes achieved through state accreditation and enhance performance in all areas of KCHD programs, services, and operations. PHAB's standards, measures, and peer-review process provided a standardized and structured way to identify meaningful opportunities for improvement and to plan and implement strategies for enhanced performance and established a platform for being recognized nationally as a high-performing local health department. The current case report highlights the way in which KCHD has developed and implemented its strategic plan to guide efforts aimed at addressing gaps identified through the accreditation process and to drive overall improvement within our agency. PMID- 29595612 TI - State Health Agencies' Perceptions of the Benefits of Accreditation. AB - The national voluntary accreditation program serves to encourage health agencies to seek departmental accreditation as a mechanism for continuous quality improvement. This study utilizes data from the 2016 Association of State and Territorial Health Officials Profile Survey to examine the perceived benefits of accreditation among state health agencies. Respondents answered questions on topics such as agency structure, workforce, and quality improvement activities. Frequencies and cross tabulations were conducted using IBM SPSS (version 21) statistical software. Results indicate that among accredited agencies, the most commonly endorsed benefits of accreditation include stimulating quality and performance improvement opportunities (95%), strengthening the culture of quality improvement (90%), and stimulating greater collaboration across departments/units within the agency (90%). Policy and practice implications, such as how these data can be used to promote accreditation within health agencies, as well as how accreditation strengthens governmental public health systems, are also discussed. PMID- 29595613 TI - Benefits and Perceptions of Public Health Accreditation Among Health Departments Not Yet Applying. AB - OBJECTIVE: To identify the benefits and perceptions among health departments not yet participating in the public health accreditation program implemented by the Public Health Accreditation Board (PHAB). DESIGN: Quantitative and qualitative data were gathered via Web-based surveys of health departments that had not yet applied for PHAB accreditation (nonapplicants) and health departments that had been accredited for 1 year. PARTICIPANTS: Respondents from 150 nonapplicant health departments and 57 health departments that had been accredited for 1 year. RESULTS: The majority of nonapplicant health departments are reportedly conducting a community health assessment (CHA), community health improvement plan (CHIP), and health department strategic plan-3 documents that are required to be in place before applying for PHAB accreditation. To develop these documents, most nonapplicants are reportedly referencing PHAB requirements. The most commonly reported perceived benefits of accreditation among health departments that planned to or were undecided about applying for accreditation were as follows: increased awareness of strengths and weaknesses, stimulated quality improvement (QI) and performance improvement activities, and increased awareness of/focus on QI. Nonapplicants that planned to apply reported a higher level of these perceived benefits. Compared with health departments that had been accredited for 1 year, nonapplicants were more likely to report that their staff had no or limited QI knowledge or familiarity. CONCLUSIONS: The PHAB accreditation program has influenced the broader public health field-not solely health departments that have undergone accreditation. Regardless of their intent to apply for accreditation, nonapplicant health departments are reportedly referencing PHAB guidelines for developing the CHA, CHIP, and health department strategic plan. Health departments may experience benefits associated with accreditation prior to their formal involvement in the PHAB accreditation process. The most common challenge for health departments applying for accreditation is identifying the time and resources to dedicate to the process.

AB - Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive genetic disorder caused by a mutation in the neurotrophic tyrosine kinase receptor (NTRK1) gene. CIPA is accompanied by abnormal catecholamine metabolism and decreased blood concentration of dopamine and norepinephrine. Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder of heterogeneous etiology and presentation, and recent reports have suggested a pathophysiological role of neurotrophins in ADHD. Furthermore, dopamine and norepinephrine are known to play major roles in the pathophysiology of ADHD, and the imbalance of monoaminergic and cholinergic systems as an underlying cause of ADHD has recently been studied. Here, we report the case of an 11-year-old boy with CIPA and comorbid ADHD. Our observations have important clinical implications for patients with CIPA. Because of deficiencies in self-control, proper management of these patients necessitates a highly structured and monitored environment, made dually important by possible comorbidity of ADHD.

PMID- 29595628 TI - What is the superior surgical strategy for bi-level cervical spondylosis-anterior cervical disc replacement or anterior cervical decompression and fusion?: A meta analysis from 11 studies. AB - BACKGROUND: Nowadays, anterior cervical artificial disc replacement (ACDR) has achieved favorable outcomes in treatment for patients with single-level cervical spondylosis. However, It is still controversial that whether or not it will become a potent therapeutic alternation in treating 2 contiguous levels cervical spondylosis compared with anterior cervical decompression and fusion (ACDF). Therefore, we conducted a systematic review and meta-analysis to compare the efficacy and safety of ACDR and ACDF in patients with 2 contiguous levels cervical spondylosis. METHODS: According to the computer-based online search, PubMed, Embase, Web of Science, and Cochrane Library for articles published before July 1, 2017 were searched. The following outcome measures were extracted: neck disability index (NDI), visual analog scale (VAS) neck, VAS arm, Short Form (SF)-12 mental component summary (MCS), SF-12 physical component summary (PCS), overall clinical success (OCS), patient satisfaction (PS), device-related adverse event (DRAE), subsequent surgical intervention (SSI), neurological deterioration (ND), and adjacent segment degeneration (ASD). Methodological quality was evaluated independently by 2 reviewers using the Furlan for randomized controlled trial (RCT) and MINORS scale for clinical controlled trials (CCT). The chi squared test and Higgin I test were used to evaluate the heterogeneity. A P < .10 for the chi-squared test or I values exceeding 50% indicated substantial heterogeneity and a random-effect model was applied; otherwise, a fixed-effect model was used. All quantitative data were analyzed by the Review Manager 5.2 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). RESULTS: Nine RCTs and 2 CCT studies containing 2715 patients were included for this meta-analysis. The pooled analysis indicated that the ACDR group is superior to ACDF in NDI, VAS neck, PCS score, OCS, PS, DRAE, ASD, and SSI. However, the pooled results indicate that there was no significant difference in the ND, VAS arm and in MCS score. CONCLUSIONS: The present meta-analysis suggests that for bi level cervical spondylosis, ACDR appears to provide superior clinical effectiveness and safety effects than ACDF. In the future, more high-quality RCTs are warranted to enhance this conclusion. PMID- 29595629 TI - Intakes of citrus fruit and risk of esophageal cancer: A meta-analysis. AB - Esophageal cancer (EC) is the eighth most common cancer and the sixth most frequent cause of cancer death in the whole world. Many studies have investigated the association between citrus fruit intake and the risk of EC, but the results are inconsistent and not analyzed by category. We aimed to perform a meta analysis of studies to evaluate the incidence between citrus fruit consumption and subtypes of esophageal cancer and derive a more precise estimation.Through searches of PubMed, OVID, and Web of Science we updated 1988 systematic review up to April 2016. Based on an inclusion and exclusion criteria, conventional meta analysis according to DerSimonian and Laird method was used for the pooling of the results. Random-effect models were used to calculate subgroups.Twenty-five English articles (20 case-control studies and 5 cohort studies) comprising totally 5730 patients of esophageal cancer would be suitable for use in this study. The result indicated the inverse associations between intakes of citrus fruit and EC (relative risk [RR] = 0.65, 95% confidence interval [CI] 0.56-0.75, I = 51.1%, P = .001), Esophageal squamous cell carcinoma (ESCC) (RR = 0.59, 95% CI 0.47-0.76, I = 60.7%, P = .002), no significant relationship between citrus fruit and esophageal adenocarcinoma (EAC) (RR = 0.86, 95% CI 0.74-1.01, I = 0.0%, P = .598).This meta-analysis indicates that intakes of citrus fruit significantly reduce the risk of ESCC and is no obvious relationship with EAC. Further studies about constituents in citrus fruit and its mechanism are warranted. PMID- 29595630 TI - Clinical and radiographic outcomes of treatment of comminuted Mason type II radial head fractures with a new implant. AB - This study aims to evaluate the clinical and radiographic treatment outcomes of comminuted Mason type II radial head fractures, which underwent open reduction and internal fixation (ORIF) using a new implant (mother-child screw, MCS).This study included 16 patients (7 male and 9 female patients; mean age: 40.9 years, age range: 19-68 years), who were treated with ORIF, followed by MCS fixation for comminuted type II radial head fractures. The clinical results were evaluated using the Mayo Elbow Performance Score (MEPS). Radiographs, which included the quality of fracture reduction, stability, osteoarthritis, and heterotopic ossification of the elbow, were investigated. The mean follow-up period was 23.4 months.Anatomical reduction and bone union were achieved in all patients treated with MCS, and mean union time was 6.2 weeks. The average flexion-extension arc of elbow motion was 135.6 degrees (range: 125 degrees -150 degrees ), and the average arc of forearm rotation was 155.3 degrees (range: 145 degrees -170 degrees ). Furthermore, MEPS was 94.1 (range: 85-100), and the rate of excellent and good was 100%. All patients returned to preinjury work within a mean period of 11.7 weeks. No heterotopic ossification and joint stiffness of the elbow were encountered. Two patients had mild arthritic changes (grade I), but none of these patients complained of pain.The use of MCS fixation for comminuted type II radial head fractures resulted in good clinical and radiographic outcomes. PMID- 29595631 TI - The efficacy of dexamethasone on pain and recovery after total hip arthroplasty: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Total hip arthroplasty (THA) perioperative dexamethasone treatment is still a controversial subject. We write this systematic review and meta-analysis to evaluate the efficacy of dexamethasone on pain and recovery after THA. METHODS: Two researchers searched the relevant studies from Pubmed, Cochrane, and Embase. The research was reported according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Randomized controlled trials (RCTs) were included in our meta-analysis. At the same time, the assessment of the risk of bias was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions version. The pooled data are processed by software RevMan 5.3. RESULT: In accordance with inclusion and exclusion, 3 studies with 207 patients were eligible and accepted into this meta-analysis. For RCTs, the risk of bias was evaluated by Cochrane Collaboration tool. Only one study did not have detection bias. Our study demonstrated that the dexamethasone group was more effective than the placebo group in term of visual analogue scale (VAS) score at 24 hours (P < .001), 48 hours (P = .04); opioid consumption (P < .001); length of stay (LOS, P < .001); and postoperative nausea (P = .001). CONCLUSION: Dexamethasone not only reduces postoperative pain scores and postoperative opioids consumption within 48 hours, but also reduces postoperative vomiting and effectively reduces LOS. However, we still need large sample size and high quality studies to explore the relationship between complications and dose response to give the final conclusion. PMID- 29595632 TI - Refractory Mycoplasma pneumoniae pneumonia with concomitant acute cerebral infarction in a child: A case report and literature review. AB - RATIONALE: Mycoplasma pneumoniae pneumonia, a common cause of community-acquired pneumonia in children, is rarely complicated with acute cerebral infarction. PATIENT CONCERNS: We present a 7-year-old boy with severe M pneumoniae pneumonia who developed impaired consciousness, aphasia, and reduced limb muscle power 7 days postadmission. DIAGNOSES: Mycoplasma pneumoniae pneumonia with concomitant acute cerebral infarction. INTERVENTIONS: The patient recovered with aggressive antibiotic therapy, antiinflammation therapy with methylprednisolone, and gamma immunoglobulin and anticoagulation therapy with aspirin and low molecular weight heparin along with rehabilitation training. OUTCOMES: At 8 days postadmission, his consciousness was improved and at the 6-month follow-up visit, his muscle power of bilateral upper and lower limbs was normal except still poor right handgrip power. LESSONS: Stroke or cerebral infarction should be considered and promptly managed in rare cases of M pneumoniae pneumonia with neurologic manifestations. PMID- 29595633 TI - Vitamin intake and pancreatic cancer risk reduction: A meta-analysis of observational studies. AB - BACKGROUND: The relationship between vitamin intake and pancreatic cancer (PC) risk is disputed. We aimed to investigate the association between vitamin intake and the risk of PC via meta-analysis. METHODS: We conducted a meta-analysis of studies concerning vitamin intake and the risk of PC from EMBASE, MEDLINE, and Cochrane Library. The search yielded 25 correlative studies including 1,214,995 individuals. The relative risks (RR) were examined by a random-effect model or fixed-effect model. Subgroup analysis, dose-response analysis, sensitivity analysis, meta-regression, and publication bias analysis were used to analyze studies. RESULTS: The RR of PC in the highest vitamin intake group was 0.90 (95% confidence interval, 0.83-0.98) compared with that in the lowest vitamin intake in the prospective studies. Different increments of vitamin intake and the risk of PC were examined with dose-response analysis, and a decrease in the risk of PC was observed with vitamin D (25%) and vitamin B12 (27%). CONCLUSIONS: This meta analysis found that vitamin intake can decrease the risk of PC, particularly vitamin D and vitamin B12. PMID- 29595634 TI - Targeted agents for patients with advanced/metastatic pancreatic cancer: A protocol for systematic review and network meta-analysis. AB - BACKGROUND: Pancreatic cancer (PC) is a devastating malignant tumor. Although surgical resection may offer a good prognosis and prolong survival, approximately 80% patients with PC are always diagnosed as unresectable tumor. National Comprehensive Cancer Network's (NCCN) recommended gemcitabine-based chemotherapy as efficient treatment. While, according to recent studies, targeted agents might be a better available option for advanced or metastatic pancreatic cancer patients. The aim of this systematic review and network meta-analysis will be to examine the differences of different targeted interventions for advanced/metastatic PC patients. METHODS: We will conduct this systematic review and network meta-analysis using Bayesian method and according to Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) statement. To identify relevant studies, 6 electronic databases including PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of science, CNKI (Chinese National Knowledge Infrastructure), and CBM (Chinese Biological Medical Database) will be searched. The risk of bias in included randomized controlled trials (RCTs) will be assessed using the Cochrane Handbook version 5.1.0. And we will use GRADE approach to assess the quality of evidence from network meta-analysis. Data will be analyzed using R 3.4.1 software. RESULTS AND CONCLUSION: To the best of our knowledge, this systematic review and network meta-analysis will firstly use both direct and indirect evidence to compare the differences of different targeted agents and targeted agents plus chemotherapy for advanced/metastatic pancreatic cancer patients. This is a protocol of systematic review and meta-analysis, so the ethical approval and patient consent are not required. We will disseminate the results of this review by submitting to a peer-reviewed journal. PMID- 29595635 TI - Aspirin plus dipyridamole has the highest surface under the cumulative ranking curves (SUCRA) values in terms of mortality, intracranial hemorrhage, and adverse event rate among 7 drug therapies in the treatment of cerebral infarction. AB - BACKGROUND: The standardization for the clinical use of drug therapy for cerebral infarction (CI) has not yet determined in some aspects. In this paper, we discussed the efficacies of different drug therapies (aspirin, aspirin plus dipyridamole, aspirin plus clopidogrel, aspirin plus warfarin, cilostazol, warfarin, and ticlopidine) for CI. METHODS: We searched databases of PubMed and Cochrane Library from the inception to April, 2017, randomized controlled trials (RCTs) met the inclusion and exclusion criteria were enrolled in this study. The network meta-analysis integrated evidences of direct and indirect comparisons to assess odd ratios (OR) and surface under the cumulative ranking curves (SUCRA) value. RESULTS: Thirteen eligible RCTs including 7 drug therapies were included into this network meta-analysis. The network meta-analysis results showed that CI patients who received aspirin plus dipyridamole presented lower mortality when compared with those received aspirin plus clopidogrel (OR = 0.46, 95% CI = 0.18 0.99), indicating aspirin plus dipyridamole therapy had better efficacy for CI. As for intracranial hemorrhage (ICH), stroke recurrence, and adverse event (AE) rate, there were no significant differences of efficacy among 7 drug therapies. Besides, SUCRA values demonstrated that in the 7 drug therapies, aspirin plus dipyridamole therapy was more effective than others (mortality: 80.67%; ICH: 76.6%; AE rate: 90.2%). CONCLUSIONS: Our findings revealed that aspirin plus dipyridamole therapy might be the optimum one for patients with CI, which could help to improve the survival of CI patients. PMID- 29595636 TI - Evidence-based practice guideline of Chinese herbal medicine for primary open angle glaucoma (qingfeng -neizhang). AB - BACKGROUND: Primary open angle glaucoma (POAG) is a chronic, progressive optic neuropathy. The aim was to develop an evidence-based clinical practice guideline of Chinese herbal medicine (CHM) for POAG with focus on Chinese medicine pattern differentiation and treatment as well as approved herbal proprietary medicine. METHODS: The guideline development group involved in various pieces of expertise in contents and methods. Authors searched electronic databases include CNKI, VIP, Sino-Med, Wanfang data, PubMed, the Cochrane Library, EMBASE, as well as checked China State Food and Drug Administration (SFDA) from the inception of these databases to June 30, 2015. Systematic reviews and randomized controlled trials of Chinese herbal medicine treating adults with POAG were evaluated. Risk of bias tool in the Cochrane Handbook and evidence strength developed by the GRADE group were applied for the evaluation, and recommendations were based on the findings incorporating evidence strength. After several rounds of Expert consensus, the final guideline was endorsed by relevant professional committees. RESULTS: CHM treatment principle and formulae based on pattern differentiation together with approved patent herbal medicines are the main treatments for POAG, and the diagnosis and treatment focusing on blood related patterns is the major domain. CONCLUSION: CHM therapy alone or combined with other conventional treatment reported in clinical studies together with Expert consensus were recommended for clinical practice. PMID- 29595637 TI - High mobility group box 1 was associated with thrombosis in patients with atrial fibrillation. AB - INTRODUCTION: High mobility group box 1 (HMGB1) is a member of the HMGB family that is involved in inflammatory disease-related thrombosis. We hypothesize that HMGB1 and its downstream factors are associated with thrombosis in atrial fibrillation (AF). MATERIALS AND METHODS: Our experimental materials were the left atrial appendage (LAA) tissues from patients undergoing valve replacement. The samples were divided into 3 groups: a sinus rhythm group (n = 15), an AF(+)thrombus(-)group (n = 15), and an AF(+) thrombus (+)group (n = 15). The expression of HMGB1, Toll-like receptor 4 (TLR4), advanced glycation end product (RAGE), myeloid differentiation factor 88 (MyD88), nuclear factor kappaB (NFkappaB), p-NFkappaB, and tissue factor (TF) were detected by Western blot and immunohistochemical (IHC) staining. The expressions of interleukin-1 beta, interleukin 6, and tumor necrosis factor-alpha were detected by quantitative real time PCR. RESULTS: The Western blots revealed significantly higher expressions of HMGB1, MyD88, p-NFkappaB/NFkappaB, and TF in the AF(+)thrombus(+) group than in the other 2 groups. However, no differences in TLR4 or RAGE expression were found between the groups. IHC staining also revealed higher expressions of HMGB1 and TF in the AF(+)thrombus(+) group. The increased mRNA expressions of classic inflammatory factors (i.e., interleukin-1 beta, interleukin 6, and tumor necrosis factor-alpha) in AF(+)thrombus(+) group further validated the correlation between inflammation and thrombi in atrial fibrillation. CONCLUSIONS: HMGB1 was associated with thrombosis in patients with AF via the MyD88/NFkappaB pathway after adjustment for cardiac and extra cardiac inflammation variables.

AB - This study aimed to compare the efficacy of thromboelastography (TEG) and conventional coagulation methods in predicting hemorrhage risk in patients with leukemia.A total of 226 patients diagnosed with leukemia were included and divided into bleeding and nonbleeding groups. All patients had their blood samples taken for TEG test to measure the reaction time (R time), alpha (alpha angle), and maximum amplitude (MA) as well as measure platelet count (PLT), prothrombin time, and activated partial thromboplastin time. Patients were followed up for bleeding episodes.The multivariate analysis showed that PLT [odds ratio (OR) = 0.993] and MA (OR = 0.921) have better association with bleeding risk. Receiver operating characteristic (ROC) analysis showed that the combination of PLT and MA (AUC = 0.824) was better for hemorrhage risk prediction than PLT [area under the curve (AUC) = 0.730] and MA (AUC = 0.819) alone.The combination of TEG and conventional coagulation methods could help in assessing the risk of hemorrhage in patients with leukemia. PMID- 29595639 TI - An overlooked cause in a patient with recurrent ischemic stroke: A case report. AB - RATIONALE: The majority of ischemic strokes are due to cardioembolism, large vessel atherothromboembolism, small vessel occlusive disease, or other unusual mechanisms. In most clinical settings, many strokes without a well-defined etiology requires a thorough diagnostic evaluation, otherwise the underlying cause might be easily overlooked. Here we report on the rare cause of a patient with recurrent stroke. PATIENT CONCERNS: A 50-year-old female patient had a 4 year history of recurrent acute onset of neurological deficits. DIAGNOSES: Contrast transcranial Doppler ultrasound detected a typical "curtain" appearance of microbubbles, indicative of a right-to-left shunt. Computed tomography pulmonary angiogram was then initiated and a pulmonary arteriovenous malformation (PAVM) in the left lower lobe was found. INTERVENTIONS: The patient underwent percutaneous closure of PAVM. Afterward, warfarin was commenced because of the high risk of further thromboembolic complications in the following weeks to months. Post-treatment computed tomography pulmonary angiogram (CTPA) demonstrated successful closure of PAVM. No microbubble signals were detected on post-treatment contrast transcranial Doppler ultrasound (TCD) study. OUTCOMES: The patient suffered no further embolic events during 3-year follow-up. No recanalization or new PAVMs were detected on CT scan. LESSONS: Neurological PAVM associated risks are common but remain poorly recognized. A strategic protocol is imperative in searching for the etiologies of cryptogenic stroke. PMID- 29595640 TI - Comparison of the effects of oxycodone versus fentanyl on airway reflex to tracheal extubation and postoperative pain during anesthesia recovery after laparoscopic cholecystectomy: A double-blind, randomized clinical consort study. AB - BACKGROUND: Fentanyl has been suggested to be effective for controlling airway and hemodynamic responses to tracheal extubation. This study was performed to compare the effects of oxycodone and fentanyl on airway and hemodynamic responses and postoperative pain during the recovery period in patients undergoing laparoscopic cholecystectomy. METHODS: Ninety patients aged 18 to 65 years were randomly allocated to 1 of 3 groups: fentanyl, oxycodone, and control. Coughing responses (incidence and severity), hemodynamic responses during the recovery period, and acute postoperative pain were assessed. RESULTS: The incidence of cough was decreased in the fentanyl and oxycodone groups compared with that in the control group at the points of awareness and extubation, and no significant difference was observed between the 2 treatment groups. Severe cough response was decreased in the fentanyl and oxycodone groups compared with that in the control group at the point of extubation, and no significant change was observed in cough severity between the 2 treatment groups. Postoperative pain scores were lower in the fentanyl and oxycodone groups than those in the control group at 5 and 30 minutes postoperatively, and no significant difference was observed between the 2 treatment groups. Hemodynamic responses did not differ among the 3 groups during the recovery period. CONCLUSION: Oxycodone treatment before tracheal extubation reduced cough response and was as effective as fentanyl treatment for improving extubation quality. Furthermore, single boluses of fentanyl and oxycodone showed equal effectiveness in attenuating acute postoperative pain in patients undergoing laparoscopic cholecystectomy. PMID- 29595641 TI - Childhood trauma interacted with BDNF Val66Met influence schizophrenic symptoms. AB - The gene - environment (G * E) interaction effect is involved in severe mental disorders. However, whether the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism participates in the childhood-abuse influenced schizophrenic symptoms remains unclear. We examined the interaction between BDNF Val66Met, and childhood trauma (ChT) on psychotic symptoms in a Chinese Han population.To estimate the G * E interaction, psychiatric interviews, self-report questionnaires for ChT, and genotyping for BDNF Val66Met were carried out on 201 schizophrenic patients. G * E interactions were analyzed by generalized multifactor dimensionality reduction (GMDR).Among all patients, 11.9%, 19.4%, 23.4%, 26.4%, and 73.6% reported emotional abuses, physical abuses (PA), sexual abuses (SA), emotional neglects (EN), and physical neglects (PN), respectively. Significant negative correlations were observed between anxiety/depression factors, and ChT total scores. Patients with 3 different BDNF genotypes showed significant differences in anxiety/depression scores. Significant 2-way interactions were found for Val66Met * PN, 3-way interactions were found for Val66Met * PN * PA, and four-way interactions were found for Val66Met * PN * PA * EN with regard to the excitement scores.Our findings suggested an involvement of BDNF Val66Met polymorphism after ChT in terms of risk for schizophrenia symptoms. PMID- 29595642 TI - Efficacy of febuxostat in hyperuricemic patients with mild-to-moderate chronic kidney disease: a meta-analysis of randomized clinical trials: A PRISMA-compliant article. AB - BACKGROUND: To investigate the efficacy of febuxostat in hyperuricemic patients with chronic kidney disease (CKD), relevant randomized clinical trials (RCTs) were analyzed. METHODS: We used PubMed, Medline, ISI Web of Science, CBMdisc, and Cochrane Library databases to conduct a systematic literature research. A fixed effects model was used to evaluate the standardized mean differences (SMDs) with 95% confidence intervals (CIs). We conducted subgroup analysis, sensitivity analysis, and analyzed publication bias, to comprehensively estimate the renoprotective effects of febuxostat in hyperuricemic patients with CKD. RESULTS: Among 296 retrieved studies, 5 relevant RCTs were included in the meta-analysis. The result showed that serum estimated glomerular filtration rate (eGFR) was improved after febuxostat treatment in hyperuricemic patients with CKD, with an SMD (95% CI) of 0.24 [-0.17 to 0.43] and P = .67 (fixed-effects model). No heterogeneity was observed across studies (I = 0% and P = .67). Subgroup analysis suggested that treatment-related reductions in serum eGFR levels were not related to drug doses, intervention times, or region. CONCLUSIONS: The present meta-analysis suggests that febuxostat may slow the progression of mild to-moderate CKD. Given the limited number of included studies, additional large sample-size RCTs are required to determine the long-term renoprotective effects of febuxostat in hyperuricemic patients with CKD.

AB - BACKGROUND: Herbal medicine treatment is often recommended in order to raise immunity levels and reduce the possibility of recurrence of symptoms, and treating the fundamental causes of the disease. This systematic review will assess the efficacy of herbal medicine in treating Behcet's disease. METHODS AND ANALYSIS: We will search the following 11 electronic databases from their inception: PubMed, EMBASE, and CENTRAL; 3 Chinese databases (CNKI, Wanfang, and VIP); and 5 Korean databases (OASIS, DBpia, RISS, KISS, and KoreaMed). The data will be extracted independently by 2 authors using predefined criteria. Disagreements will be resolved by discussion between the authors. The risk of bias will be assessed using the Cochrane tool for assessing risk of bias. ETHICS AND DISSEMINATION: Ethical approval will not be required, given that this protocol is for a systematic review. The review will be published in a journal. Updates of the review will be conducted periodically to inform and guide healthcare practice and policy. TRIAL REGISTRATION NUMBER: PROSPERO 2018 CRD42018085493. PMID- 29595645 TI - Effectiveness of liposome bupivacaine for postoperative pain control in total knee arthroplasty: A PRISMA-compliant meta-analysis of randomized controlled trials. AB - BACKGROUND: Adequate pain control after total knee arthroplasty (TKA) enables quicker recovery and reduces readmissions and treatment costs. The aim of this study was to determine the effect of liposomal bupivacaine (LB) for postoperative pain control in patients prepared for TKA. METHODS: We searched for the reports that evaluating the effect of liposomal bupivacaine for postoperative pain control in patients prepared for TKA between March 1983 and May 2017 in the electronic database Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, and Ovid. The main outcomes were visual analog scale (VAS) at 24, 48, and 72 hours. The secondary outcomes were total morphine consumption, the length of hospital stay, range of motion, and the occurrence of nausea. RESULTS: Seven randomized controlled trials (RCTs) enrolling 825 patients, with 413 in the LB group and 412 in the control group, were included in this meta-analysis. Our results suggested that administration LB was associated with a reduction of VAS by 4.22 points at 72 hours after TKA (WMD = -4.22, 95% CI -7.47, -0.97, P = .011) on a 100-point VAS. What's more, LB can decrease the occurrence of nausea when compared with traditional bupivacaine by 18.3% (risk ratio = 0.70, 95% confidence interval 0.55, 0.89, P = .003). LB was associated with an increase of the range of motion than traditional bupivacaine (P < .05). There was no significant difference between the VAS at 24, 48 hours, total morphine consumption and the length of hospital stay. CONCLUSIONS: Administration with LB was associated with pain-relieving effects and reduces the morphine related complications (nausea). Due the limited number of the included RCTs, large number and high quality RCTs are still need to identify the effects of LB for pain control after TKA. PMID- 29595646 TI - Urological complications after radical hysterectomy with postoperative radiotherapy and radiotherapy alone for cervical cancer. AB - Radiotherapy is a reliable method to cure cervical cancer patients, but it could cause serious urological complications after the treatment due to the anatomical location of the cervix. The main purpose of this retrospective analysis is to study the incidence, latency, and therapeutic efficacy of urological complications caused by radical hysterectomy with postoperative radiotherapy or radiotherapy alone in patients with cervical cancer.A retrospective analysis was conducted on patients with cervical cancer who received radical hysterectomy with postoperative radiotherapy or radiotherapy alone at the First Hospital of Jilin University between January 2010 and May 2016. The urological complications were confirmed by clinical manifestation, ultrasound, computed tomography (CT), nuclear scintigraphy, and assessment of renal function. All the patients with urological complications received conventional treatment, including conservative, electrosurgery, ureteral stents, nephrectomy, and neoplasty. The onset time of radiation injury symptoms was confirmed according to the medical history and follow-up. The surveillance for the therapeutic effects for these complications was accomplished by cystoscopy, imaging, and laboratory assessment.The overall rate of urological complications after treatment was 3.26%, comprising 2.12% ureteral obstruction, 0.98% radiocystitis, and 0.16% vesicovaginal fistula. The incidence of ureteral obstruction in patients treated with radical hysterectomy with postoperative radiotherapy and radiotherapy alone was not statistically significant (2.18% vs 1.59%, P > .05). The median onset time of radiocystitis and ureteral obstruction was 10 months (0-75 months) and 12 months (2-66.3 months), respectively. The onset time of vesicovaginal fistula was 3.5 months. After the appropriate treatment, the majority of the complications were under control.The incidence of urological complications is acceptable. There was no statistical difference in the risk between patients treated with radical hysterectomy with postoperative radiotherapy and radiotherapy alone. The latency period between radiotherapy and the manifestation of urological complications may be relatively long. So it is crucial to underline long-term follow-up after radiotherapy. The majority of urological complications were alleviated after symptomatic treatment and the patients with cervical cancer achieved long-term remissions or cures. PMID- 29595647 TI - Ultrasound-guided minimally invasive percutaneous nephrolithotomy in the treatment of pediatric patients <6 years: A single-center 10 years' experience. AB - Owing to the fragile kidney and relative small collecting system of pediatric patients, urologists were always reluctant to treat pediatric urolithiasis with PCNL. Here we conduct a study to assess the effectiveness and safety of pediatric patients with renal calculi <6 years.A total of 88 pediatric patients (99 kidney units) <6 years underwent the ultrasound (US)-guided minimally invasive percutaneous nephrolithotomy in our institute from March 2006 to April 2016. The mean age was 30.9 months (range, 7-72 months). The mean stone size was 19.5 mm (range, 10-50 mm). The group included single stone in 35 kidney units, upper ureteral stone in 12 kidney units, multiple stone in 43 kidney units, and staghorn stone in 9 kidney units. The procedure of puncture and dilation were guided by US solely.The mean operation time was 52.3 minutes (range, 15-140 minutes). The mean postoperative length of stay was 6.0 days (3-16 days). Besides, the initial stone free rate (SFR) was 90.9% (90/99) and the final SFR was 96.0% (95/99). The mean hemoglobin drop was 10.9 g/L (range, 1-25 g/L). Postoperative complications occurred in 12 patients including fever in 11 cases and active pleural effusion in 1 case.The US-guided MPCNL is an effective and safety procedure to treat pediatric patients with stone <6 years. PMID- 29595648 TI - Clinical application of the sinus tarsi approach in the treatment of intra articular calcaneal fracture. AB - To observe the clinical outcome of the sinus tarsi approach in the operative treatment of intra-articular calcaneal fractures.Forty-nine intra-articular calcaneal fractures in 45 patients were managed surgically with sinus tarsi approach. The anatomical plate and compression bolts were applied in 14 feet. The anatomical plate and screws were applied in 35 feet. Maryland foot score system was used to evaluate the function of the hindfoot at the followup.The reduction of the posterior facet was graded as nearly anatomical (less than 2 mm articular displacement) in 46 feet (93.9%). The width, height, and Bohler angle were significantly improved in all patients (P < .01). After a mean follow-up period of 18.7 months (14.5-29 months), the Maryland foot scores were: 34 feet scored 90 100 points (excellent), 6 feet scored 80-90 points (good), 6 feet scored 70-80 points (fair), and 3 feet scored 60-70 points (poor). Incision-edge necrosis occurred in 2 cases. One case suffered from incomplete medial plantar nerve injury. One case suffered from heel pad branch of the tibial nerve injury. Six cases suffered from sural nerve injury, and 4 cases sustained a lateral wound dehiscence due to a hematoma. No case suffered from lateral impingement syndrome. Up to now, no patient had to accept subtalar arthrodesis.Sinus tarsi approach provides good exposure to the subtalar joint. Open reduction and internal fixation of calcaneus fractures through a sinus tarsi approach allows adequate reduction with low risk of wound-healing complications. PMID- 29595649 TI - Next-generation sequencing provides an added value in determining drug resistance and viral tropism in Cameroonian HIV-1 vertically infected children. AB - With limited and low-genetic barrier drugs used for the prevention of mother-to child transmission (PMTCT) of HIV in sub-Saharan Africa, vertically transmitted HIV-1 drug-resistance (HIVDR) is concerning and might prompt optimal pediatric strategies.The aim of this study was to ascertain HIVDR and viral-tropism in majority and minority populations among Cameroonian vertically infected children.A comparative analysis among 18 HIV-infected children (7 from PMTCT exposed mothers and 11 from mothers without PMTCT-exposure) was performed. HIVDR and HIV-1 co-receptor usage was evaluated by analyzing sequences obtained by both Sanger sequencing and ultra-deep 454-pyrosequencing (UDPS), set at 1% threshold.Overall, median (interquartile range) age, viremia, and CD4 count were 6 (4-10) years, 5.5 (4.9-6.0) log10 copies/mL, and 526 (282-645) cells/mm, respectively. All children had wild-type viruses through both Sanger sequencing and UDPS, except for 1 PMTCT-exposed infant harboring minority K103N (8.31%), born to a mother exposed to AZT+3TC+NVP. X4-tropic viruses were found in 5 of 15 (33.3%) children (including 2 cases detected only by UDPS). Rate of X4-tropic viruses was 0% (0/6) below 5 years (also as minority species), and became relatively high above 5 years (55.6% [5/9], P = .040. X4-tropic viruses were higher with CD4 <=15% (4/9 [44.4%]) versus CD4 >15% (1/6 [16.7%], P = .580); similarly for CD4 <=200 (3/4 [75%]) versus CD4 >200 (2/11 [18.2%] cells/mm, P = .077.NGS has the ability of excluding NRTI- and NNRTI-mutations as minority species in all but 1 children, thus supporting the safe use of these drug-classes in those without such mutations, henceforth sparing ritonavir-boosted protease inhibitors or integrase inhibitors for the few remaining cases. In children under five years, X4-tropic variants would be rare, suggesting vertical-transmission with CCR5-tropic viruses and possible maraviroc usage at younger ages. PMID- 29595650 TI - Accuracy and safety of ultrasound-guided percutaneous needle core biopsy of renal masses: A single center experience in China. AB - Our aim is to determine the sufficiency, accuracy, and safety of ultrasound guided percutaneous needle core biopsy of renal masses in Chinese patients.Patients who had undergone ultrasound-guided needle core renal mass biopsy from June 2012 to June 2016 at West China Hospital, China were retrospectively reviewed. The information obtained included demographics, mass related parameters, biopsy indications, technique, complications, pathologic results, and follow-up. Concordance of surgical resection pathology and follow-up data were assessed.Renal mass biopsies were performed in 106 patients. Thirty nine (36.8%) were asymptomatic. The male/female ratio was 60/46, with a median age of 49.5 years. Median mass size was 8.1 cm (range 1.8-20). Biopsy was performed through a 16-gauge needle, with median cores of 2 taken (range 1-5). Only one significant biopsy-related complication (hemorrhage requiring transfusion) was encountered. An adequate tissue sample was obtained in 97.2% (103/106) of biopsies. Eighty-seven biopsies (82.1%) showed malignant neoplasms, 16 (15.1%) yielded benignity, and 3 (2.8%) were nondiagnostic. After biopsy, 46 patients (43.4%) underwent surgery. Compared with the subsequent mass resection pathology, the biopsy diagnoses were identical in 43 cases. The accuracy rate of biopsy distinguishing malignant from benign lesions was 99.1%, and the rate for determining tumor histological type (excluding the nondiagnostic biopsies) was 95.1%. The sensitivity and specificity in detecting malignancy were 98.9% and 100%, respectively.In several situations, there is still a role for biopsy before intervention. Percutaneous needle core biopsy under ultrasonography guidance is highly accurate and safe, and can determine the proper management of undefinable masses. PMID- 29595651 TI - Bronchoscopic valve placement for the treatment of persistent air leaks. AB - Persistent air leaks (PALs) are associated with increased morbidity, prolonged hospital stay, and increased treatment costs. Endobronchial 1-way valves have been recently used as a potential less invasive treatment option. We sought to investigate the effects of valve therapy in treating this condition. The patients with evidence of continuous air leak flow whose chest tubes remained in place for more than 7 days were treated with bronchoscopic closure using 1-way valves. The source of the air leak was identified by the Chartis system.A total of 11 patients (1 woman, 10 men; mean age, 68 years) who underwent valve placement were eligible to be enrolled from January 2015 through January 2017. Six patients had postoperative PAL, and 5 had a secondary spontaneous pneumothorax. The number of used valves varied from 1 to 3 (median 1). The resolution of the leak was complete in 8 patients (72.7%), whose mean duration of air leak before and after valve deployment was 58.5 and 4.5 days, respectively. There were no complications related to the valve deployment.Bronchoscopic placement of 1-way valves is a safe procedure that could help manage patients with prolonged PALs. A prospective randomized trial with cost-efficiency analysis is necessary to better define the role of this bronchoscopic intervention and demonstrate its effect on air leak duration. PMID- 29595652 TI - Determinants of lymph node count and positivity in patients undergoing surgery for colon cancer. AB - Prognosis in colon cancer is based on pathological criteria including TNM staging. However, there are deficiencies in this approach, and the lymph node ratio (LNR) has been proposed to improve the prediction of outcomes. LNR is dependent on optimal retrieval of lymph nodes-lymph node count (LNC). Recent studies have suggested that an elevated preoperative systemic inflammatory response (SIR) was associated with a lower LNC and a higher LNR. However, there are a number of potential confounding factors. The aim of the present study was to examine, in detail, these relationships in a large cohort of patients.A prospectively maintained database of all patients undergoing colon cancer resection in our institution was examined. The SIR was measured by a number of inflammatory markers and their scores: modified Glasgow Prognostic Score (mGPS) (C-reactive protein/albumin), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and lymphocyte monocyte ratio (LMR) using standard thresholds. The relationships between LNC and LNR, and clinicopathological characteristics (including the mGPS, NLR, PLR, and LMR) were examined using chi square test for trend and binary logistic regression analysis, where appropriate.Of the 896 patients included in the study, 418 (47%) were male, the median LNC was 17 (1-71), and the median LNR in node positive disease was 0.16 (0.03-1). On multivariate analysis, there was a significant independent relationship between an elevated LNC (>=12) and laparoscopic surgery (P < .001), right-sided tumors (P < .001), later date of resection (2007-2016) (P < .001), T stage (P < .001), and venous invasion (P < .001). In those patients with a LNC >=12 and node-positive disease (n = 272), on multivariate analysis, there was a significant relationship between an elevated LNR (>=0.25), and T stage (P < .01) and differentiation (P < .05). Finally, in patients with node-positive disease who had surgery later (2007-2016), LNR was directly superior to N stage for both cancer-specific survival (LNR: hazard ratio [HR] 2.62, 95% confidence interval [CI] 1.25-5.52, P = .011) and overall survival (LNR: HR 2.02, 95% CI 1.12-3.68, P = .022).Neither LNC nor LNR was associated with markers of the SIR; however, LNC and LNR were directly associated. In high-quality surgical and pathological practice, LNR had superior prognostic value compared with N stage in patients undergoing surgery for colon cancer. PMID- 29595653 TI - Type I Gaucher disease with bullous pemphigoid and Parkinson disease: A case report. AB - RATIONALE: Gaucher disease (GD) is a rare genetic lysosomal storage disorder inherited in an autosomal recessive pattern. GD is due to the deficiency of a lysosomal enzyme, acid beta-glucosidase (or glucocerebrosidase). Type 1 Gaucher disease (GD1) is characterized by thrombocytopenia, anemia, an enlarged spleen, and liver as well as bone complications (Erlenmeyer flask deformity, osteoporosis, lytic lesions, pathological and vertebral fractures, bone infarcts, and avascular necrosis leading to degenerative arthropathy). The diagnosis is usually made in first decades but is sometimes delayed. Parkinson disease, neoplasia, and immune system abnormalities may be associated with GD1. PATIENT CONCERNS: A patient known for hepatosplenomegaly with hyperferritinemia, anemia, and thrombocytopenia was admitted for Lewy body dementia and bullous pemphigoid. DIAGNOSES: Type 1 Gaucher disease. INTERVENTION: No specific treatment started. OUTCOMES: patient died ten months later due to pneumonia. LESSONS: To the best of our knowledge, this is the first case of the association between GD1, bullous pemphigoid, and Lewy body dementia. We discuss the central role of alpha synuclein in these pathologies. PMID- 29595654 TI - Traumatic C1-2 rotatory subluxation with dens and bilateral articular facet fractures of C2: A case report. AB - RATIONALE: To the best of our knowledge, this is an extremely rare case of traumatic C1-2 rotatory subluxation associated with multiple C2 fractures. PATIENT CONCERNS: We report the case of a 63-year-old man with type 2 traumatic C1-2 rotatory subluxation (Fielding and Hawkins classification) associated with type III dens (Anderson and D'Alonzo classification) and bilateral articular facet fractures of C2. This injury occurred as a result of falling down in a drunken state. The patient complained of neck pain and mild degree of torticollis but did not show any neurologic abnormalities. DIAGNOSES: Plain radiographs of cervical spine showed extensive soft tissue swelling, a fracture fragment, disruption of spinolaminar line at C1-2 level, and bony overlapping of right side lateral joint of C1-2. Two- and three-dimensional reconstructed computed tomography scans clearly demonstrated complicated C1-2 combined injury. The atlantodental interval was normal. INTERVENTION: By skull traction and derotation, closed reduction of C1-2 rotatory subluxation with a type III dens and bilateral articular facet fractures of C2 was successfully achieved. He was managed with halovest fixation for 3 months. OUTCOMES: At the 1-year follow-up visit solid fusion and improvement of clinical symptoms were achieved without C1 2 instability. LESSONS: Despite traumatic C1-2 rotatory subluxation associated with multiple C2 fractures, trial of closed reduction should be considered as the first choice of treatment so as to preserve C1-2 motion. PMID- 29595655 TI - The prognostic value of circulating cell-free DNA in breast cancer: A meta analysis. AB - BACKGROUND: Circulating cell-free DNA (cfDNA) isolated from plasma or serum by noninvasive procedures can serve as a "liquid biopsy" and has potential as a biomarker for the tumor burden and survival prediction of breast cancer (BC). However, its prognostic value in patients with BC is currently under debate. The aim of this meta-analysis was to investigate the relationship between cfDNA and survival outcome. METHODS: We systematically searched PubMed, Embase, and Science Citation Index electronic databases for studies about the prognostic utility of cfDNA in patients with BC. The clinical characteristics, relapse/disease-free survival (RFS/DFS), and overall survival (OS) data were extracted from the eligible studies. The hazard ratios (HR) and 95% confidence intervals (CI) were calculated and pooled with a fixed-effects model using the Stata12.0 software. Subgroup and sensitivity analyses were also performed. RESULTS: This meta analysis included a total of 10 eligible studies and 1127 patients with BC. The pooled HR with 95% CI showed strong associations between cfDNA and OS (HR = 2.41, 95% CI, 1.83-3.16) along with DFS/RFS (HR = 2.73, 95% CI, 2.04-3.67) in patients with BC. Although publication bias was found in the studies regarding RFS/DFS, further trim and fill analysis revealed that the adjusted HR would be 2.53 (95% CI, 1.83-3.51), which is close to the original HR. Subgroup analyses confirmed the role of cfDNA as a strong prognostic marker in patients with BC, regardless of cfDNA analysis, sampling time, sample source, detection method, tumor stage, sample size, or area. CONCLUSIONS: Our meta-analysis indicates that cfDNA is a strong predictive and prognostic marker in patients with BC. PMID- 29595656 TI - The association between myocardial infarction and intravitreal bevacizumab injection. AB - To evaluate the risk of myocardial infarction (MI) after receiving intravitreal bevacizumab (IVB) injection. We retrospectively reviewed the charts of patients who had received IVB injection in 2016, and grouped them according to whether they received the injection for age-related macular degeneration (AMD), diabetes related complications, or retinal vein occlusion (RVO). We then investigated the prevalence of MI within 2 months after IVB injection and analyzed the possible association of IVB with MI. During 2016, 724 patients were enrolled and received a total of 1870 IVB injections. Seven patients were diagnosed with MI within 2 months after receiving an IVB injection. Of 274 patients with AMD, 2 were diagnosed with MI; of 311 patients with diabetes-related complications, 3 were diagnosed with MI; and of 139 patients with RVO, 2 were diagnosed with MI (P = 0.785). All MIs occurred between 3 days and 3 weeks after IVB injection (mean = 14.00 +/- 6.45 days). The MIs after receiving IVB were associated with previous history of MI or cerebrovascular infarction in multivariate logistic regression analysis (P = 0.005). There was no significant difference in MI prevalence after IVB injection according to the reason for receiving the injection. However, care should be taken when administering IVB injections, especially to patients with risk factors such as history of MI or cerebrovascular infarction. PMID- 29595657 TI - Analysis of epidural waveform for cervical epidural steroid injections confirmed with fluoroscopy. AB - The identification of epidural space with loss of resistance (LOR) is commonly performed. But it lacks specificity. Epidural pressure waveform analysis (EPWA) provides a simple confirmative adjunct for LOR. If the needle is located within the epidural space, measurement of the pressure at its tips shows a pulsatile waveform. Previous studies demonstrated satisfactory sensitivity and specificity of EPWA. However, success or failure of epidural injection was confirmed by the pinprick test, which is limited for patients in the setting of the pain clinic. In this study, we evaluated the sensitivity, specificity, as well as positive and negative predictive values of EPWA for cervical epidural steroid injection (CESI) confirmed by fluoroscopy.One hundred and five CESIs of 75 patients suffering from neck and radicular arm pain of over 3 months duration were enrolled. The physician injected 5 mL of normal saline after a feeling of satisfactory LOR. Saline filled extension tubing, connected to a pressure transducer, was attached to the needle. A 3 mL bolus of contrast medium was injected to confirm the success of CESI.The incorrect identification of epidural space with LOR (false LOR) was 29.5%. Of these 31 failed CESIs, 2 showed epidural waveform and 29 did not. The sensitivity, specificity, positive and negative predictive value of EPWA was 94.5%, 93.5%, 97.2%, and 87.7%, respectively.EPWA shows satisfactory reliability and is a simple adjunct to decrease false LOR for CESI. Further confirmative studies are required before its routine use in clinical practice. PMID- 29595658 TI - High scavenger receptor class B type I expression is related to tumor aggressiveness and poor prognosis in lung adenocarcinoma: A STROBE compliant article. AB - Scavenger receptor class B type I (SR-B1) is highly expressed in a variety of cancers, including prostate, breast and ovarian. However, the relationship between SR-B1 and lung adenocarcinoma is unknown. We analyzed the expression of SR-B1 in a well-characterized lung adenocarcinoma tissue microarray by immunohistochemistry, in 90 cancerous and 90 adjacent normal lung tissues. Results showed that the positive expression rate of SR-B1 in cancer tissues (86/90, 96%) was significantly higher than that of adjacent tissues (50/90, 56%) (P < .001). And SR-B1 overexpression in lung adenocarcinoma tissue was significantly higher than that of adjacent normal tissue (P < .001), accounting for 67% of cases. This elevated SR-B1 expression was associated with AJCC stage (P < .001), T stage (P = .012), N stage (P = .002), and lymph node positivity (P < .001). The Kaplan-Meier survival analysis indicated that patients with high SR B1 expression had a shorter overall survival (P < .001). On the multivariate analysis, SR-B1 was an independent prognostic factor for outcomes after adjustment for other prognostic factors (P = .038). In conclusion, high SR-B1 expression is associated with conventional pathologic parameters that represent tumor aggressiveness and may purport a poor clinical prognosis in lung adenocarcinoma. PMID- 29595659 TI - Change in radial artery pulse wave in stroke hemiplegic patients: Protocol for a case-control study. AB - INTRODUCTION: About 55% to 75% of stroke survivors have motor disorders and problems that affect their quality of life. The prevention of secondary neurological damages through relapse prevention and the rehabilitation of stroke patients suffering from morbidities are crucial to improve the prognosis of patients with stroke. Pulse examinations can be used to determine the stroke progression. This study will investigate the differences and changes in radial artery pressure-pulse waves during the treatment of hemiplegia caused by stroke. METHODS/DESIGN: This study protocol is for a prospective matched case-control study. A total of 84 participants will be recruited, 56 patients with hemiplia caused by stroke, and 28 control patients matched by age, gender, and body mass index. The primary outcome of this study will be the differences and changes in the radial augmentation index. DISCUSSION: The results of the study will help to determine the differences and changes in radial artery pressure-pulse waves during the treatment of hemiplegia caused by stroke. The findings will provide information about the physiological and hemodynamic mechanisms. CONCLUSION: This will be the first study to analyze the pulse wave of the radial artery (PWRA) on the affected side and on the normal side in stroke patients with hemiplegia. This study will clarify whether the radial artery pressure pulse wave can be used to evaluate the result of stroke treatment objectively. The results of the study will be available in February 2019. The version of the protocol is v1.6 written in March 7, 2016. ETHICS AND DISSEMINATION: Written informed consent will be obtained from all participants. This study has been approved by the Institutional Review Board (IRB) of Wonkwang University Gwangju Hospital, Gwangju, Republic of Korea (WKIRB-2016/8). The study findings will be published in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: This trial was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0002147). PMID- 29595660 TI - Sealing of the cystic and appendix arteries with monopolar electrocautery during laparoscopic combined cholecystectomy and appendectomy. AB - The best method to ligate the arteries during laparoscopic cholecystectomy or appendectomy remains controversy. The aim of this study is to introduce a new approach during laparoscopic combined cholecystectomy and appendectomy using a monopolar electrocautery to seal the cystic and appendix arteries. We retrospectively reviewed data from 57 patients who underwent laparoscopic combined cholecystectomy and appendectomy between December 2006 and June 2016. Each laparoscopic combined cholecystectomy and appendectomy was performed by coagulating and sealing the cystic and appendix arteries. Absorbable clip or coils were then used to ligate the proximal of cystic duct and the stump of appendix. The other side of the cystic duct and appendix which subsequently were to be removed from abdomen were used titanium clips or silk ligature. Of the 57 patients, 3 patients (5.3%) were converted to open surgery due to severe abdominal adhesions or gallbladder perforation. The mean operative time was 56 minutes (range, 40-80 minutes). Mean blood loss was 12 mL (range, 5-120 mL), and the mean postoperative hospital stay was 3.0 days (range, 2-5 days). No postoperative bleeding, biliary leakage, infection, or mortality occurred. Monopolar electrocautery to seal the cystic and appendix arteries is a safe, effective, and economical surgical procedure during laparoscopic combined cholecystectomy and appendectomy. Further randomized controlled clinical trials are required to validate our findings. PMID- 29595661 TI - Fine needle biopsy is superior to fine needle aspiration in endoscopic ultrasound guided sampling of pancreatic masses: A meta-analysis of randomized controlled trials. AB - BACKGROUND: The comparison between endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) and EUS guided fine needle biopsy (FNB) in sampling pancreatic masses is still controversial. METHODS: A systematic search was conducted in PubMed and Web of Science to identify all relevant randomized controlled trials (RCTs). Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated for dichotomous outcomes of interest (specimen adequacy, diagnostic accuracy, complications, and technical success), while mean difference (MD) and 95% CI were pooled for continuous variables (number of needle passes required for diagnosis). RESULTS: Eleven RCTs were identified with a total of 694 EUS-FNA cases and 688 EUS-FNB cases. Compared with EUS-FNA, EUS-FNB had a better specimen adequacy (OR: 1.83, 95% CI: 1.27-2.64), higher diagnostic accuracy (OR: 1.62, 95% CI: 1.17 2.26), and fewer number of needle passes (MD: 0.69, 95% CI: 1.18 to 0.20). No significant difference was found in complications (OR: 1.01, 95% CI: 0.27-3.78) and technical success (OR: 0.13, 95% CI: 0.02-1.07). CONCLUSION: EUS-FNB is superior to EUS-FNA in sampling pancreatic masses. PMID- 29595662 TI - Difference between elderly and non-elderly patients in using serum lactate level to predict mortality caused by sepsis in the emergency department. AB - Elderly people are more susceptible to sepsis and experience more comorbidities and complications than young adults. Serum lactate is a useful biomarker to predict mortality in patients with sepsis. Lactate production is affected by the severity of sepsis, organ dysfunction, and adrenergic stimulation. Whether the predictive ability of serum lactate will be different between non-elderly and elderly patients is unknown.A retrospective cohort study was conducted to compare the prognostic value of hyperlactatemia in predicting the mortality between elderly (>=65 years) and non-elderly (<65 years) patients with sepsis.This is a single-center retrospective observational cohort study conducted from January 2007 to December 2013 in southern Taiwan. All patients with sepsis, who used antibiotics, with blood culture collected, and with available serum lactate levels in the emergency department, were included in the analysis. We evaluated the difference in serum lactate level between the elderly and non-elderly septic patients by using multiple regression models.A total of 7087 patients were enrolled in the study. Elderly and non-elderly patients accounted for 62.3% (4414) and 40.2% (2673) of all patients, respectively. Statistically significant difference of serum lactate levels was not observed between elderly and non elderly survivors (2.9 vs 3.0 mmol/L; P = .57); however, elderly patients had lower lactate levels than those within the 28-day in-hospital mortality (5.5 vs 6.6 mmol/L, P < .01). Multiple logistic regression revealed higher adjusted mortality risk in elderly and non-elderly patients with lactate levels of >=4.0 mmol/L (odds ratio [OR], 4.98 and 5.82; P < .01, respectively), and lactate level between 2 and 4 mmol/L (OR, 1.57 and 1.99; P < .01, respectively) compared to that in the reference group with lactate levels of <2.0 mmol/L in each group. In receiver operating characteristic curve analysis, sensitivity rates for predicting mortality were 0.80 and 0.77 for non-elderly and elderly patients, respectively, by using serum lactate levels higher than 2.0 mmol/L.Septic elderly non-survivors had 1 mmol/L lower serum lactate level than those of the non elderly non-survivors. Lactate >2 mmol/L still could provide enough sensitivity in predicting sepsis mortality in elder patients. PMID- 29595663 TI - Cytochrome P450 1A1 gene polymorphisms and cervical cancer risk: A systematic review and meta-analysis. AB - OBJECTIVE: This meta-analysis aims to examine whether the MspI and Ile462Val polymorphisms of cytochrome P450 1A1 (CYP1A1) are associated with cervical cancer risk. METHODS: Eligible case-control studies were identified dated until July 2017. Pooled odds ratios (ORs) were used to assess the strength of the association between the two variants and cervical cancer risk. RESULTS: Thirteen studies were eligible (2148 cases and 2252 controls) concerning MspI polymorphism and 8 studies were eligible (1466 cases and 1690 controls) for Ile462Val polymorphism. MspI polymorphism seemed to result in cervical cancer risk in any genetic model (C allele vs T allele: OR = 1.44, 95% confidence interval [CI] = 1.16-1.79; heterozygous model: OR = 1.40, 95% CI = 1.08-1.82; homozygous model: OR = 2.22, 95% CI = 1.48-3.33, dominant model: OR = 1.50, 95% CI = 1.14-1.98 and recessive model: OR = 1.80, 95% CI = 1.35-2.41); similar significantly increased risk was found among Caucasians and Asians. Ile462Val polymorphism was associated with elevated cervical cancer risk (Val allele vs Ile allele: OR = 1.85, 95% CI = 1.27-2.67; heterozygous model: OR = 1.42, 95% CI = 1.28-1.61; homozygous model: OR = 2.94, 95% CI = 1.15-7.54; dominant model: OR = 2.00, 95% CI = 1.33-3.00); this finding was replicated upon Caucasian population. CONCLUSION: This meta analysis demonstrated that polymorphisms in MspI and Ile462Val of CYP1A1 were risk factors for developing cervical cancer. PMID- 29595664 TI - Roles of T follicular helper cells in the pathogenesis of adenoidal hypertrophy combined with secretory otitis media. AB - The aim of this study was to investigate the roles of T follicular helper (Tfh) cells in secretory otitis media (SOM) combined with adenoidal hypertrophy (AH).Patients with AH or AH combined with SOM admitted to the Yancheng No. 1 People's Hospital from December 2012 to December 2014 were included. Fourteen age matched healthy individuals received physical examinations in the hospital served as control. The venous Tfh was determined using flow cytometry, and CD3 + CD4 + CXCR5 + T lymphocytes were defined as Tfh cells. Serum inflammatory factors including IL-8, IL-1b, IL-6, IL-10, TNF, IL-12p70, IL-21, and IgE were determined using commercial kits.Compared with the AH group, the number of CD4 + CXCR5 + T cells in peripheral blood of the AH combined with SOM group showed significant increase. Statistical differences were noticed in the number of the number of CD4 + CXCR5 + T cells in moderate and severe AH groups compared with that of the control group. Statistical differences were identified in the proportion of CD4 + CXCR5 + T cells in the adenoidal tissues between the AH combined with SOM group and AH group (P < .05). For the CD4 + CXCR5 + T cells in adenoidal tissues, no statistical differences were noticed between the moderate and severe AH groups (P > .05). The number of CD4 + CXCR5 + T cells was positively correlated to the serum IL-21. Nevertheless, no correlation was noticed between CD4 + CXCR5 + T cell and serum IL-8, IL-6, IL-10, and IgE.Tfh is involved in the AH combined with SOM in children. Besides, serum IL-21, IL-8, IL-6, IL-10, and IgE may be involved in the onset of SOM in children. PMID- 29595665 TI - Saddle embolism treated by thrombolysis and thrombus aspiration via bilateral femoral artery puncture catheter: A case report. AB - INTRODUCTION: Abdominal aortic saddle embolism is a rare and severe disease with the manifestation of abrupt onset, rapid progression and high mortality. Endovascular therapy becomes a new option for this disease due to its minor trauma, less complications, no requirement for general anesthesia or abdominal incisions, and shorter hospitalization duration. METHODS: A 50-year-old female was diagnosed as abdominal aortic saddle embolism, and thrombus aspiration was given immediately via bilateral femoral artery puncture catheter along with artery indwelling catheter thrombolysis. RESULTS: The saddle embolism was removed completely. After 1-month follow-up, the computed tomography angiography (CTA) examination showed neither stenosis nor thrombus in the abdominal aorta and iliac artery. The patient achieved perfect outcome. CONCLUSIONS: Endovascular therapy may be an optional solution for saddle embolism. PMID- 29595666 TI - Components of metabolic syndrome increase the risk of mortality in nonalcoholic fatty liver disease (NAFLD). AB - Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States. Metabolic syndrome (MS) components are highly prevalent in NAFLD. Our aim is to assess the relationship of NAFLD and MS with long-term outcome of mortality.The Third National Health and Nutrition Examination Survey (NHANES) was utilized. NAFLD was diagnosed by ultrasound in the presence of hepatic steatosis and no other causes of chronic liver disease. History of MS and its components were obtained from self-reported NHANES questionnaires. Mortality was obtained from Mortality-Linkage File, through December 31, 2011. Chi-square test was used for categorical variables and Cox proportional models estimated hazard ratios with 95% confidence interval.NAFLD cohort (n = 3613) had a median age of 43 years, 73% white, and 50% male. NAFLD group with at least one MS condition was significantly older, had higher body mass index, more likely to have insulin resistance, and heart disease compared to NAFLD group without MS. Over 19-years of follow-up, 1039 people died. Compared to NAFLD patients without MS, presence of one MS component increased the risk of mortality at 8-year (2.6% vs 4.7%) and 16-year (6% vs 11.9%) (P < .001). After adjusting for socio-demographic factors, NAFLD with all MS components was associated with overall, cardiac and liver-mortality. Increased number of MS components was associated with lower survival (P < .0001).Patients with NAFLD and MS have higher mortality risk compared to NAFLD patients without MS. These NAFLD patients should be prioritized for the development of treatment regimens. PMID- 29595667 TI - Association between BACE1 gene polymorphisms and focal seizures in a Chinese Han population. AB - BACKGROUND: Beta-secretase 1 (BACE1) is attracting increasing attention for its vital role in pathogenesis of many neuropsychiatric disorders and many studies also have indicated BACE1 as a possible risk factor for seizures, but not any studies have reported association between BACE1 gene polymorphisms and seizures. Therefore, we investigated the possible association between focal seizures and BACE1 gene polymorphisms in the present study. METHODS: A total of 162 patients and 211 health controls were enrolled in this study and polymorphisms of BACE1 gene were detected using polymerase chain reaction (PCR)-ligase detection reaction method. RESULTS: The frequency of genotype AT for BACE1 rs535860 (A>T) was significantly higher (24.1%) in patients compared to controls (14.7%) (OR = 1.836, 95% CI = 1.086-3.102, P = .023). Intriguingly, we only found the significant difference of BACE1 SNP genotype and allele frequency among males but not females. However, no statistically significant results were presented for the genotype distributions of rs525493 (G>T) and rs638405(C>G) polymorphisms between patients and controls. CONCLUSION: Our study demonstrated there may exist an association between BACE1 rs535860 (A>T) polymorphism and focal seizures in Chinese Han males. PMID- 29595668 TI - Fennel (Foeniculum vulgare) on management of menopausal symptoms: A protocol for systematic review of randomized controlled trials. AB - BACKGROUND: Fennel (Foeniculum vulgare) is often used in women's health care to treat dysmenorrhea, increase the milk supply, and address symptoms of menopause. The object of this review is to evaluate the current evidence on the efficacy of fennel for the management menopausal symptoms. METHODS AND ANALYSES: Thirteen databases will be searched from their inception to the present. These include PubMed, AMED, EMBASE, the Cochrane Library, six Korean medical databases (Korean Studies Information Service System, DBPIA, the Korean Institute of Science and Technology Information, the Research Information Service System, KoreaMed, and the Korean National Assembly Library), and 3 Chinese databases (the China National Knowledge Infrastructure Database [CNKI], the Chongqing VIP Chinese Science and Technology Periodical Database [VIP], and Wanfang Database). Study selection, data extraction, and assessments will be performed independently by 2 researchers. The risk of bias will be assessed using the Cochrane risk of bias tool. ETHICS AND DISSEMINATION: Ethical approval is not required, given that this protocol is for a systematic review only. The review will be published in a peer reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy. TRIAL REGISTRATION NUMBER: PROSPERO 2018 CRD42018085698. PMID- 29595669 TI - Integrative medicine for managing the symptoms of lupus nephritis: A protocol for systematic review and meta-analysis. AB - BACKGROUND: Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE).

PMID- 29595670 TI - Acupuncture for chronic pelvic inflammatory disease: A systematic review protocol. AB - BACKGROUND: Chronic pelvic inflammation disease (PID) is a difficult-to-treat gynecological disorder with complex etiologies. Acupuncture has been applied widely for treating chronic pelvic inflammation or chronic pelvic pain symptoms in China. The aim of this review is to undertake a systematic review to estimate the effectiveness and safety of acupuncture on chronic PID. METHODS: A literature search will be conducted electronically with date up to October 2018 in MEDLINE, Cochrane Library, EBASE, and CNKI databases, using combination subject terms of chronic pelvic pain (or chronic pelvic inflammation, and chronic pelvic pain symptoms, etc.) and acupuncture related treatment. Also duplicates will be removed. The primary outcomes consisted of improvement rate and pain relief. Secondary outcomes include the recurrence rate and side effects, such as pneumothorax, bleeding, serious discomfort, subcutaneous nodules, and infection. Systematic reviews and databases will be searched for randomized controlled trials on acupuncture for chronic PID with acupuncture treatment will be included. Cochrane RevMan V5.3.5 risk of bias assessment tool will be implemented for risk of bias evaluation, data synthesis, meta-analyses, and subgroup analysis while condition is met. Mean difference (MD), standard mean difference (SMD), and dichotomous data will be used to present continuous outcomes. RESULTS: This study will generate a comprehensive review of current evidence of acupuncture for chronic pelvic inflammation diseases. CONCLUSION: The study will provide updated evidence to evaluate the effectiveness and side effects of acupuncture for chronic pelvic inflammation disease. PROSPERO REGISTRATION NUMBER: CRD42018087950. PMID- 29595672 TI - A case report of a man on peritoneal dialysis having intractable hyponatremia. AB - RATIONALE: Hyponatremia is one of the most common electrolyte disorders in patients on peritoneal dialysis (PD). It can be associated with severe consequences, higher morbidity and mortality. Therefore, hyponatremia should be assessed and monitored more carefully in these patients. PATIENT CONCERNS: A 55 year-old male PD patient progressively developed intractable hyponatremia was admitted to our hospital. DIAGNOSES: The observation that no significant salt was lost in kidney and PD drainage prompted us to seek the underlying reasons for malnutrition and chronic inflammation. And cancer and tuberculosis were further suspected, although the exact nature at last was not clearly determined due to the unfavorable prognosis. INTERVENTIONS: The hyponatremia can hardly be improved by adjusting ultrafiltration close to zero, increasing sodium intake from 2.5 g to 7g, and nutrition counselling to maintain protein intake 0.9-1.2 g/kg/day and calorie intake 27-35 kcal/kg/day. Due to poor general situation, he received tentative anti-tuberculosis treatment instead of surgery for intracranial space occupying lesion. OUTCOMES: He died at home with conservative therapy. LESSONS: It highlighted the challenge for differential diagnosis and treatment in the hyponatremia on PD patient. PMID- 29595671 TI - Effect of intravenous lidocaine infusion on long-term postoperative pain after spinal fusion surgery. AB - BACKGROUND: Intravenous lidocaine infusion is known to reduce postoperative pain for days or weeks beyond the infusion time, and plasma half-life in several types of surgical procedures. OBJECTIVES: To evaluate the effect of intravenous (IV) lidocaine infusion on long term postoperative pain intensity for 3 months in patients undergoing spinal fusion surgery. STUDY DESIGN: Prospective randomized, double-blinded study. SETTING: Assiut University Hospital, Assiut, Egypt. METHODS: Forty patients undergoing spinal fusion surgery were randomized into 2 equal groups (n = 20 in each). Patients in the lidocaine group received IV lidocaine at a dosage of 2.0 mg/kg slowly before induction of anesthesia, followed by lidocaine IV infusion at a rate of 3.0 mg/kg/h until the end of surgery. Patients in the control group received an equal volume of normal saline. The following data were assessed: pain by Visual Analog Score (VAS) at 1 hour, 6 hours, 12 hours, 24 hours, 48 hours, at discharge time, and at 1 month, 2 months, and 3 months post-operation, time to first request for additional analgesia, and total morphine consumption in 24 hours. RESULTS: Lidocaine significantly reduced the postoperative pain score (VAS) for up to 3 months (P < .05), and significantly reduced morphine consumption (4.5 mg vs. 19.85 mg) in the 1st 24 hours postoperative. Lidocaine also significantly, prolonged (P < .05) the time to first request for additional analgesia (9.56 +/- 2.06 hours vs 1.82 +/- 0.91 hours). CONCLUSION: Intra-operative lidocaine, when given intravenously as a bolus followed by an infusion, significantly decreased long term postoperative back pain intensity in patients undergoing spinal fusion surgery. PMID- 29595673 TI - Implants for orthodontic anchorage: An overview. AB - Implantanchorage continues to receive much attention as an important orthodontic anchorage. Since the development of orthodontic implants, the scope of applications has continued to increase. Although multiple reviews detailing implants have been published, no comprehensive evaluations have been performed. Thus, the purpose of this study was to comprehensively evaluate the effects of implants based on data published in review articles.An electronic search of the Cochrane Library, Medline, Embase, Ebsco and Sicencedirect for reviews with "orthodontic" and "systematic review or meta analysis" in the title, abstract, keywords, or full text was performed. A subsequent manual search was then performed to identify reviews concerning orthodontic implants. A manual search of the orthodontic journals American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), European Journal of Orthodontics (EJO), and Angle Othodontist was also performed. Such systematic reviews that evaluated the efficacy and safety of orthodontic implants were used to indicate success rates and molar movements.A total of 23 reviews were included in the analysis. The quality of each review was assessed using a measurement tool for Assessment of Multiple Systematic Reviews (AMSTAR), and the review chosen to summarize outcomes had a quality score of >6. Most reviews were less than moderate quality. Success rates of implants ranged in a broad scope, and movement of the maxillary first molar was superior with implants compared with traditional anchorage. PMID- 29595674 TI - Outcomes of modified trapeziectomy with ligament reconstruction tendon interposition for the treatment of advanced thumb carpometacarpal arthritis: Two year follow-up. AB - Numerous arthroplasty techniques had been reported for the treatment of thumb carpometacarpal (CMC) joint osteoarthritis. The purpose of our study is to evaluate long-term clinical and radiographic outcomes of patients who underwent modified trapeziectomy with ligament reconstruction tendon interposition (LRTI).Our retrospective study included 20 consecutive patients with advanced thumb CMC arthritis receiving modified trapeziectomy with LRTI (20 thumbs). For clinical evaluation, we assessed visual analogue scale (VAS), Disabilities of the Arm, Shoulder and Hand (DASH) scores and Kapandji index. Additionally, the grip, pinch power and waist flexion power, radial and volar abduction angle were evaluated, As for radiologic evaluation, we just estimated height of the trapezial space.We took 2-year follow-up. All patients showed decreased VAS from 6.8 preoperatively to 1.4. Mean DASH and Kapandji scores were improved from 52.2 preoperatively to 21.6 and from 6.4 preoperatively to 7.4, respectively. Compared to preoperative range of motion (ROM) for radial abduction and volar abduction, both markedly increased at 2-year follow-up (from 61.2 to 80.1, from 60.6 to 78.3, respectively). Besides, mean power improved from 15.9 preoperatively to 21.7 kg at 2-year follow-up for grip power, from 1.9 preoperatively to 3.5 kg at 2-year follow-up for tip pinch; however, mean waist flexion power showed no significant change from 20.5 preoperatively to 19.7 kg at 2-year follow-up. Notably, there was no significant sinking in height of the trapezial space from 10.0 preoperatively to 9.6 mm at 2-year follow-up. NO case had a complication at final follow-up.Modified trapeziectomy with LRTI treating thumb CMC arthritis in Eaton stage III-IV had a satisfactory efficacy. This new procedure is able to provides enough support for thumb to prevents thumb sinking. PMID- 29595675 TI - A 12-year analysis of closed medical malpractice claims of the Taiwan civil court: A retrospective study. AB - Malpractices lawsuits cause increased physician stress and decreased career satisfaction, which might result in defensive medicine for avoiding litigation. It is, consequently, important to learn experiences from previous malpractice claims. The aim of this study was to examine the epidemiologic factors related to medical malpractice claims, identify specialties at high risk of such claims, and determine clinical which errors tend to lead to medical malpractice lawsuits, by analyzing closed malpractice claims in the civil courts of Taiwan.The current analysis reviewed the verdicts of the Taiwan judicial system from a retrospective study using the population-based databank, focusing on 946 closed medical claims between 2002 and 2013.Among these medical malpractice claims, only 14.1% of the verdicts were against clinicians, with a mean indemnity payment of $83,350. The most common single specialty involved was obstetrics (10.7%), while the surgery group accounted for approximately 40% of the cases. In total, 46.3% of the patients named in the claims had either died or been gravely injured. Compared to the $75,632 indemnity for deceased patients, the mean indemnity payment for plaintiffs with grave outcomes was approximately 4.5 times higher. The diagnosis groups at high risk of malpractice litigation were infectious diseases (7.3%), malignancies (7.2%), and limb fractures (4.9%). A relatively low success rate was found in claims concerning undiagnosed congenital anomalies (4.5%) and infectious diseases (5.8%) group. A surgery dispute was the most frequent argument in civil malpractice claims (38.8%), followed by diagnosis error (19.3%).Clinicians represent 85.9% of the defendants who won their cases, but they spent an average of 4.7 years to reach final adjudication. Increased public education to prevent unrealistic expectations among patients is recommended to decrease frivolous lawsuits. Further investigation to improve the lengthy judicial process is also necessary to relieve the stress of medical malpractice claims on clinicians and practitioners, as well as on the judicial system and rightful claimants. PMID- 29595676 TI - A single-center observational study on the efficacy of percutaneous coronary intervention for ischemic heart failure: A cohort study. AB - The effects of revascularization by percutaneous coronary intervention (PCI) on cardiac function and clinical outcomes in patients with confirmed coronary artery disease (CAD) and heart failure (HF), on the basis of the optimal medical treatment recommended by current guidelines, remain to be determined.A cohort study was performed to evaluate the efficacy of PCI on the basis of optimal medical treatment in patients with CAD and HF. Patients who received PCI were subsequently grouped according to partial and complete revascularization (CR) depending on the PCI outcome. The primary outcome was defined as a composite outcome of major adverse cardiovascular events (MACEs). Changes in left ventricular ejection fraction (LVEF) also were compared.A total of 69 patients (12 who received medical treatment and 57 who received PCI) were included. Patients in the PCI group showed significantly improved LVEF (P < .001), but patients in the medical treatment group did not (P > .05) after 3 months of follow-up. MACEs occurred in 50% patients in the medical treatment group and 19.3% patients of the PCI group, with this difference almost reaching statistical significance (P = .06). Compared with patients who received medical therapy only, patients who received PCI experienced better survival (P = .02). Moreover, survival seemed to be better in patients who achieved CR with PCI of the coronary arteries than in those who had partial revascularization of the coronary arteries (P = .06).PCI may be effective for improving survival in patients with CAD and HF.

AB - Because of its rarity, the exact imaging features of ectopic thyroid are poorly known.To analyze the value of scintigraphy, computed tomography (CT), magnetic resonance imaging (MRI), and single-photon emission computed tomography (SPECT)/CT in the diagnosis of ectopic thyroid in the head and neck.First, we retrospectively analyzed the scintigraphy, CT, MRI, and SPECT/CT images from 25 masses (22 patients) suspected of head and neck ectopic thyroid from 2006 to 2017 at the Shanghai Ninth People's Hospital. Each mass was imaged by nuclear imaging (scintigraphy with or without SPECT/CT) and radiological exam (CT and/or MRI). Pathological examination was considered as the gold standard. Secondly, thirteen malignant ectopic thyroids in the head and neck reported in the English literature from 2001 to 2017 were retrieved for comparison.The accuracy of scintigraphy was not significantly higher than that of CT (94.7%, vs 89.5%, P > .99) or MRI (92.3%, vs 84.6%, P > .99). Five masses which underwent scintigraphy with SPECT/CT were all true positive, while 1 was false negative on MRI, and 2 were false negative on CT. Compared to the benign ectopic thyroids in our study, the 13 malignant ectopic thyroids retrieved from the literature were grossly the same in shape, margins, and invasion on CT or MRI.The number of patients was limited, but scintigraphy combined with SPECT/CT could be a reliable method for the diagnosis of ectopic thyroid. Benign and malignant ectopic thyroids appear to be similar in shapes, margins, and invasion on CT or MRI. PMID- 29595678 TI - Early changes in fibrinogen after administration of alteplase are associated with the short-term efficacy of thrombolysis. AB - The authors aimed to determine whether early changes in fibrinogen were associated with the efficacy of intravenous thrombolysis at 24 hours after alteplase infusion. The authors retrospectively reviewed a consecutive series of 56 patients with acute ischemic stroke treated with alteplase in the clinical database. The fibrinogen levels were monitored at the first and fourth hours after alteplase infusion. Additionally, the National Institutes of Health Stroke Scale (NIHSS) scores were recorded to define the short-term efficacy of intravenous thrombolysis before and 24 hours after alteplase infusion. The patients were distributed into amelioration, deterioration, and inefficiency groups according the short-term efficacy of intravenous thrombolysis. One-way ANOVA and post hoc analysis were used to compare the differences in the clinical characteristics among these groups. The relationships among changes in the fibrinogen levels, other potential risk factors, and NIHSS scores were examined using logistic regression analysis. Fifty-two patients (mean age, 65.71 +/- 11.04 years; male, 57.7%) were finally enrolled in the study. The median NIHSS of these patients was 11 (range, 2-23), and the mean time from symptom onset to thrombolysis was 187.17 +/- 67.53 minutes. The frequency of hypertension in the deterioration group was significantly higher than that in the inefficiency group (P = .01). Changes in the fibrinogen level were more significant in the amelioration group than in the other groups (P < .05). Logistic regression analysis revealed that changes in the fibrinogen levels between the first and fourth hours were positively associated with the short-term efficacy of alteplase infusion (odds ratio, 3.98; 95% confidence interval, 1.56-10.16; P = .004). Early changes in fibrinogen levels may be a potential predictor for the short-term efficacy of alteplase treatment in acute ischemic stroke. Additionally, these changes may be helpful for determining the short-term efficacy of alteplase treatment and early therapeutic strategies in clinical practice. PMID- 29595680 TI - Assessment of the periodontal health status in patients undergoing orthodontic treatment with fixed appliances and Invisalign system: A meta-analysis. AB - BACKGROUND: At present, many scholars have studied the periodontal health status of patients undergoing orthodontic treatment with fixed appliances and invisalign. However, those results are inconsistent. Therefore, we conducted this meta-analysis, and then provide reference for clinical treatment. METHODS: Most databases, such as the Cochrane Library, EMBASE, PubMed, Medline, Chinese Biomedical Literature Database, CNKI, and Wan Fang Data were retrieved for related articles from the establishment of the database to October 2017. Meanwhile, we also searched the references of the related literatures manually, in order to increase the included literatures. Two researchers screened the related literatures according to the inclusion criteria and exclusion criteria. Stata 12.0 software was used for data analysis, and results are estimated by odds ratio (OR) and 95% confidence interval (CI). RESULTS: Finally, 7 articles, including 368 patients, were included into our meta-analysis. Meta-analysis results showed that there was no statistically significant difference of gingival index (GI) and sulcus probing depth (SPD) status between the invisalign group and the control group, including at 1, 3, and 6 months (all P > .05). When compared with the control group, the invisalign group presented a lower plaque index (PLI) and sulcus bleeding index (SBI) status at 1 month (OR = -0.53, 95% CI: -0.89 to 0.18; OR = -0.44, 95% CI: -0.70 to -0.19, respectively), 3 months (OR = -0.69, 95% CI: -1.12 to -0.27; OR = -0.49, 95% CI: -0.93 to -0.05, respectively), and 6 months (OR = -0.91, 95% CI: -1.47 to -0.35; OR = -0.40, 95% CI: -0.63 to -0.07, respectively). Subgroup analysis showed that the SPD status was lower in the invisalign group at 6 months when measured the teeth using Ramfjord index (OR = 0.74, 95% CI: -1.35 to -0.12). However, there was no statistically significant difference between the 2 groups when using other measure methods (OR = 0.12, 95% CI: -0.26 to 0.17). CONCLUSION: Our meta-analysis suggests that comparing with the traditional fixed appliances, patients treated with invisalign have a better periodontal health. However, more studies are needed to confirm this conclusion in the future. PMID- 29595681 TI - Value of free/total prostate-specific antigen (f/t PSA) ratios for prostate cancer detection in patients with total serum prostate-specific antigen between 4 and 10 ng/mL: A meta-analysis. AB - BACKGROUND: Prostate carcinoma is a common disease that occurs in men over 50 years old. Many studies have explored the effect of free/total prostate-specific antigen (f/t PSA) ratio in monitoring prostate cancer. We conducted a meta analysis to identify the accuracy of the f/t PSA ratio in the diagnosis of prostate cancer in patients who have PSA levels of 4 to 10 ng/mL. METHODS: Databases searched included PubMed and OVID databases, from inception to March 2017, after a systematical review, sensitivity, specificity, and other measures of accuracy of the f/t PSA ratio in the diagnosis of prostate cancer were pooled. We used summary receiver operating characteristic curves to summarize overall test performance. RESULTS: Fifteen case-control studies from 14 articles were identified. The results indicated that the sensitivity of the f/t PSA ratio in the diagnosis of prostate cancer ranged from 0.5 to 0.94 (pooled sensitivity 0.70, 95% CI: 0.67-0.72), whereas its specificity ranged from 0.31 to 0.93 (pooled specificity 0.55, 95% CI: 0.57-0.60). The positive likelihood ratio was 1.85 (95% CI: 1.56-2.20), negative likelihood ratio was 0.42 (95% CI: 0.34-0.53), and diagnostic odds ratio was 4.81 (9.53% CI: 3.33-6.94). CONCLUSIONS: The f/t PSA ratio determination has a low sensitivity and specificity for the diagnosis of prostate cancer; it would not be useful for the diagnosis of prostate cancer by itself. The results of f/t PSA ratio measurements should refer to the clinical manifestations and the results of conventional tests such as biopsies. PMID- 29595679 TI - Central nervous system histoplasmosis: Multicenter retrospective study on clinical features, diagnostic approach and outcome of treatment. AB - Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment.Twenty nine percent of patients were not immunosuppressed. Histoplasma antigen, or anti-Histoplasma antibodies were detected in the cerebrospinal fluid (CSF) in 75% of patients. One year survival was 75% among patients treated initially with amphotericin B, and was highest with liposomal, or deoxycholate formulations. Mortality was higher in immunocompromised patients, and patients 54 years of age, or older. Six percent of patients relapsed, all of whom had the acquired immunodeficiency syndrome (AIDS), and were poorly adherent with treatment.While CNS histoplasmosis occurred most often in immunocompromised individuals, a significant proportion of patients were previously, healthy. The diagnosis can be established by antigen, and antibody testing of the CSF, and serum, and antigen testing of the urine in most patients. Treatment with liposomal amphotericin B (AMB-L) for at least 1 month; followed by itraconazole for at least 1 year, results in survival among the majority of individuals. Patients should be followed for relapse for at least 1 year, after stopping therapy. PMID- 29595682 TI - Salvage preoperative embolization of an infratemporal solitary fibrous tumor: A case report with review of the literature. AB - RATIONALE: Head and Neck Solitary fibrous tumors (SFT) are very rare. They could be misdiagnosed as hemangiopericytomas (HPC). PATIENT CONCERNS: We report a 60 y o lady presenting with sinonasal mass, causing recurrent profuse bleeding. DIAGNOSES: Hemangioperocytomas versus SFT were among the differentials, according to Radiological studies. Upon Biopsy, the diagnosis of SFT has been adopted. INTERVENTIONS: Salvage pre-operative embolization resulted in bleeding control, bridging the patient to surgery. OUTCOMES: Post-operative course was uneventful, and patient symptoms resolved. LESSONS: This is the first case report of a sinonasal SFT, where pre-operative embolization has been employed as a salvage procedure. This treatment modality is promising, since it controls bleeding, bridges patient to surgery and decreases blood loss during the surgical procedure. PMID- 29595683 TI - Mapping the human brain during a specific Vojta's tactile input: the ipsilateral putamen's role. AB - A century of research in human brain parcellation has demonstrated that different brain areas are associated with functional tasks. New neuroscientist perspectives to achieve the parcellation of the human brain have been developed to know the brain areas activation and its relationship with different stimuli. This descriptive study aimed to compare brain regions activation by specific tactile input (STI) stimuli according to the Vojta protocol (STI-group) to a non-STI stimulation (non-STI-group). An exploratory functional magnetic resonance imaging (fMRI) study was performed. The 2 groups of participants were passively stimulated by an expert physical therapist using the same paradigm structure, although differing in the place of stimulation. The stimulation was presented to participants using a block design in all cases. A sample of 16 healthy participants, 5 men and 11 women, with mean age 31.31 +/- 8.13 years was recruited. Indeed, 12 participants were allocated in the STI-group and 4 participants in the non-STI-group. fMRI was used to map the human brain in vivo while these tactile stimuli were being applied. Data were analyzed using a general linear model in SPM12 implemented in MATLAB. Differences between groups showed a greater activation in the right cortical areas (temporal and frontal lobes), subcortical regions (thalamus, brainstem, and basal nuclei), and in the cerebellum (anterior lobe). STI-group had specific difference brain activation areas, such as the ipsilateral putamen. Future studies should study clinical implications in neurorehabilitation patients. PMID- 29595684 TI - Gastric metastasis from invasive lobular breast cancer, mimicking primary gastric cancer: A case report. AB - RATIONALE: Gastric metastasis from invasive lobular breast cancer is relatively rare, commonly presented among multiple metastases, several years after primary diagnosis of breast cancer. Importantly, gastric cancer that is synchronously presented with lobular breast cancer can be misdiagnosed as primary gastric cancer; therefore, accurate differential diagnosis is required. PATIENT CONCERNS: A 39-year-old woman was visited to our hospital because of right breast mass and progressive dyspepsia. DIAGNOSES: Invasive lobular carcinoma of breast was diagnosed on core needle biopsy. Gastroscopy revealed a diffuse scirrhous mass at the prepyloric antrum and diagnosed as poorly differentiated adenocarcinoma on biopsy. Synchronous double primary breast and gastric cancers were considered. Detailed pathological analysis focused on immunohistochemical studies of selected antibodies, including those of estrogen receptors, gross cystic disease fluid protein-15, and caudal-type homeobox transcription factor 2, were studied. As a result, gastric lesion was diagnosed as metastatic gastric cancer originating from breast. INTERVENTIONS: Right breast conserving surgery was performed, and duodenal stent was inserted under endoscopic guidance to relieve the patient's symptoms. Systemic chemotherapy with combined administration of paclitaxel and trastuzumab was initiated. OUTCOMES: Forty-one months after the diagnosis, the patient is still undergoing the same therapy. No recurrent lesion has been identified in the breast and evidence of a partial remission of gastric wall thickening has been observed on follow-up studies without new metastatic lesions. LESSONS: Clinical suspicion, repeat endoscopic biopsy, and detailed histological analysis, including immunohistochemistry, are necessary for diagnosis of metastatic gastric cancer from the breast. PMID- 29595685 TI - Double-blind placebo-controlled randomized clinical trial on the use of paracetamol for performing mammography. AB - BACKGROUND: This study was conducted within the Goias Mastology Research Network. To verify the possibility of diminishing pain, and discomfort during the mammography using analgesic administration. METHODS: Randomized, double-blinded, placebo controlled trial, testing paracetamol to diminish the pain, and discomfort during mammography. Three hundred patients who came for screening mammography were randomized for this study. A questionnaire with 2 parts was used: the first had questions that concerned the patient identification, and factors related to the pain during mammography; and the second asked about the scale of discomfort (no discomfort; uncomfortable; very uncomfortable; intolerable), and the pain (analogical linear scale) during the mammography. Each patient received 1000 mg of paracetamol, or placebo. Afterwards each patient filled out the second part of the questionnaire. Six patients were excluded from the analysis; this resulted in 149 in the paracetamol group, and 145 in the placebo group. RESULTS: The 2 groups were homogenous concerning the mean of the ages, weight, height, and breast size. The mean of the pain was 3.5 in the paracetamol, and 2.8 in the placebo group (P = .12). There were fewer women experiencing mild pain in the paracetamol group when compared with those in placebo group (relative risk [RR] 0.76, confidence interval [CI] 95% 0.52-0.98). There was no significant difference between the 2 groups, according to the degrees of discomfort (P = .69). CONCLUSION: The use of paracetamol can reduces the mild pain for women undergoing mammography. PMID- 29595686 TI - Risk factors and outcomes of sepsis-induced myocardial dysfunction and stress induced cardiomyopathy in sepsis or septic shock: A comparative retrospective study. AB - While both sepsis-induced myocardial dysfunction (SIMD) and stress-induced cardiomyopathy (SICMP) are common in patients with sepsis, the pathogenesis of the 2 diseases is different, and they require different treatment strategies. Thus, we aimed to investigate risk factors and outcomes between the 2 diseases.This retrospective study enrolled patients diagnosed with sepsis or septic shock, admitted to intensive care unit via emergency department in Korea University Anam Hospital, and who underwent transthoracic echocardiography within the first 24 hours of admission.In all, 25 patients with SIMD and 27 patients with SICMP were enrolled. Chronic obstructive pulmonary disease and a history of heart failure (HF) were more prevalent in both the SIMD and SICMP groups than in the control group. In the SIMD and SICMP groups, levels of inflammatory cytokines were similar. Serum troponin level was significantly elevated in the SICMP and SIMD group compared to the control group. N-terminal pro-brain natriuretic peptide (NT pro-BNP) level was significantly elevated in the SIMD group compared to the SICMP group or control group. The in-hospital mortality rate in the SIMD and SICMP group was about 40%, showing increased trends compared with the control group. The in-hospital mortality rate was significantly increased in SIMD group with EF<30% than in SICMP group with EF<30%. In multiple logistic regression analysis, a past history of diabetes mellitus (DM) and HF was significantly associated with the incidence of SIMD. Younger age, elevated levels of NT pro BNP, and positive result of blood culture also showed significant odds ratio regard to the occurrence of SIMD. However, only elevated lactate and troponin level were positively associated with the incidence of SICMP.The SIMD and SICMP had different risk factors. The risk factors of SIMD were younger age, history of DM, history of HF, elevated NT pro-BNP, and positive result of blood culture. The elevated levels of lactate and troponin were identified as risk factors of SICMP. More importantly, in-hospital mortality rate from SIMD and SICMP showed increased trend and worse outcome in SIMD group with reduced EF<30%. Thus, developing SIMD or SICMP reflected poor prognosis in sepsis or septic shock. PMID- 29595687 TI - Effectiveness and safety of Glycyrrhizae Decoction for Purging Stomach-Fire in Behcet disease patients: Study protocol for a randomized controlled and double blinding trail. AB - BACKGROUND: Behcet disease (BD) is a worldwide-occurred autoimmune disorder and currently lack of optional successful treatment. An ancient traditional Chinese medical formula called Glycyrrhizae Decoction for Purging Stomach-Fire (GDPSF) was recorded and nowadays has been observed to be effective for BD patients. However, the strict randomized controlled and double-blinding trail is needed to further assess this alternative medicine. METHODS: To ascertain the potential effects and safety of GDPSF for BD patients and to determine whether combination application of GDPSF and thalidomide could possibly reduce the side effects and increase effectiveness for BD management, we will conduct a randomized, double blind, controlled clinical trial. Patients enrolled will be randomly assigned into 3 groups: GDPSF group, thalidomide group, and integrative group (treated by both GDPSF and thalidomide). Participants will receive treatment for 6 months and accept a 12 months follow-up. Before and after treatment, clinical manifestations, blood tests, thalidomide dosage, remission levels, quality of life, and satisfactory levels will be assessed. The data of assessments on each group before and after treatments will be collected and analyzed through historical control, while between groups through intergroup control. Then statistical analysis will be applied to assess the effects and safety. DISCUSSION: This study protocol will assess the effects and safety of GDPSF for BD patients GDPSF. Combination application of GDPSF and thalidomide might be a new integrative medical method for BD patients.

PMID- 29595689 TI - Single-port surgery (SPS) strategy for small bowel obstruction (SBO) caused by postoperative internal hernia: A series case report. AB - RATIONALE: Internal hernia due to postoperative adhesions sometimes causes small bowel obstruction (SBO) and requires emergency surgery. The difficulties in the management of SBO with internal hernia include accurate diagnosis and estimation of its ischemic degree and of the risk of SBO recurrences following the surgical procedure. Laparoscopic surgery is a noninvasive to reduce postoperative adhesions and therefore has been widely used recently. However, surgeons often tend to hesitate in applying laparoscopic surgery for SBO because of some situational disadvantages such as poor operating space or iatrogenic bowel injury. Hence, laparoscopic surgery is still not yet the standard procedure for SBO caused by internal hernia. Thus, the establishment of an appropriate procedure for SBO due to internal hernia is required. PATIENT CONCERNS: We experienced 3 SBO cases caused by postoperative internal hernia. The first patient was a 59-year-old man who had temporary loop-ileostomy for a perforated sigmoid colon due to diverticulitis. Severe hypogastralgia and vomiting occurred suddenly on the 33rd postoperative day. The second patient was an 81-year-old man who had been hospitalized due to epigastralgia of unknown origin. He had a surgical history of omentum patching for a perforated duodenum 20 years ago. The third patient was a 72-year-old female who presented at our hospital after sudden and severe hypogastralgia. She had a surgical history of sigmoidectomy for her sigmoid colon cancer 22 years ago. DIAGNOSIS: A contrast computed tomography (CT) revealed a suspected closed loop obstruction of their bowels and immediate surgical treatments were required. INTERVENTION: We tried SPS using the surgical glove method as an initial approach for their SBO caused by postoperative internal hernia. OUTCOMES: Two of these 3 cases completely underwent SPS treatment, which afforded accurate diagnosis of SBO. Laparotomy following SPS, which allowed accurate diagnosis, was judged to be appropriate and was performed in the third case. All the patients were discharged without any complications and SBO have not recurred after their discharge. Finally, we established a new strategy using SPS for SBO with internal hernia. LESSONS: Our experience suggests that SPS is a promising strategy as an initial surgical approach for SBO with internal hernia.

PMID- 29595690 TI - A novel index including SNPs for the screening of nonalcoholic fatty liver disease among elder Chinese: A population-based study. AB - Presently noninvasive methods were employed to the diagnosis of nonalcoholic fatty liver disease (NAFLD), including fatty liver index (FLI), hepatic steatosis index (HSI), product of fasting triglyceride and glucose levels (TyG), and single nucleotide polymorphism (SNP), whereas the accuracy of those indexes need to be improved. Our study aimed to investigate the feasibility of a new index comprehensive index (CI), consisting of 6 serum biomarkers and anthropometric parameters through multivariate logistic regression analysis, to the earlier detection of NAFLD, and the diagnostic value of 5 SNPs (S1: rs2854116 of apolipoprotein C3 [APOC3], S2: rs4149267 of ATP-binding cassette transporter [ABCA1], S3: rs13702 of lipoprotein lipase [LPL], S4: rs738409 of protein 3 [patatin-like phospholipase domain containing protein 3 (PNPLA3)], S5: rs780094 of glucokinase regulatory protein gene [GCKR]) for NAFLD were also explored. Area under the receiver operating characteristic curves (AUROC) and Youden index (YI) were calculated to assess the diagnostic value. The AUROC of CI was higher than FLI, HSI, and TyG (CI: 0.897, FLI: 0.873, HSI: 0.855, TyG: 0.793). Therefore, CI might be a better index for the diagnosis of NAFLD. Although there had no statistical significance (P = .123), the AUROC and YI were increased when CI combined with rs2854116 (S1) (AUROC = 0.902, YI = 0.6844). The combination of CI with S1 showed even better diagnostic accuracy than CI, which suggests the potential value of rs2854116 for the diagnosis of NAFLD. PMID- 29595692 TI - Color Doppler ultrasound diagnosis of intrarenal vein thrombosis: A rare case report and literature review. AB - RATIONALE: We present a case of intrarenal vein thrombosis (IRVT) diagnosed by ultrasound (US). To the best of our knowledge, this is the first reported case in the imaging literature. PATIENT CONCERNS: A 15-year-old boy with a 4-year history of thrombocytopenic purpura presented to the emergency room with a 2-day history of sudden-onset severe left flank pain associated with gross hematuria. DIAGNOSES: Hypercholesterolemia, proteinuria, and elevated plasma creatinine level were present. The US examination showed obscurely structured, sparsely distributed arterial and venous flow signals, and an increased resistance index (RI) in a localized area. The diagnosis was acute renal failure and nephrotic syndrome accompanied by left IRVT. INTERVENTIONS: The patient was treated with anticoagulation therapy for 1 month. OUTCOMES: Clinical symptoms were relieved. The US re-examination revealed that the arterial flow spectra had returned to normal. Also, more venous flow signals were observed in the involved area, suggesting thrombolysis. LESSONS: This previously unreported case should alert sonographers to include IRVT in the differential diagnosis of flank pain associated with hematuria. In such cases, both kidneys and different areas of the same kidney should be scanned and compared. Some features, including an obscure structure and an increased RI for the involved area indicate possible IRVT. PMID- 29595693 TI - Perianal atypical leiomyoma: A case report: Erratum. PMID- 29595694 TI - Translation and validation of the Simplified Chinese version of Western Ontario Osteoarthritis of the Shoulder Index (WOOS). AB - To produce a cross-cultural adaptation and translation of the English version of the Western Ontario Osteoarthritis of the Shoulder index (WOOS) into Simplified Chinese and to validate its reliability, validity, and responsiveness.A total of 52 consecutive patients were included. The inclusion criteria were as follows: diagnosed to have primary shoulder osteoarthritis (OA) and referred to undergo conservative treatment, able to speak Chinese, and able to read Simplified Chinese. WOOS, the Oxford Shoulder Score (OSS), and Short Form 36 (SF-36) were filled at the first visit, and WOOS alone was filled at the second visit with an interval of 3 to 7 days after the first visit. Four months after appropriate treatments, the WOOS was again sent to patients by e-mail for the evaluation of responsiveness.The intraclass correlation coefficient ranged from 0.90 to 0.98, which showed good test-retest reliability. As we had hypothesized, construct validity was high according to a significant correlation among WOOS, SF-36 (3 subscales, namely physical functioning, bodily pain, and role-physical), and OSS. High responsiveness was documented by the evaluation of standard response mean (from 1.09 to 1.33) and effect size (from 0.80 to 0.97).The Simplified Chinese version of WOOS (SC-WOOS) was shown to be a reliable, valid instrument for evaluating the quality of life of patients suffering from shoulder OA in China. PMID- 29595695 TI - Comamonas kerstersii bacteremia in a patient with acute perforated appendicitis: A rare case report. AB - RATIONALE: Comamonas species are rarely associated with human infections. Recent reports found that Comamonas kerstersii was associated with severe diseases such as abdominal infection and bacteremia. However, C. kerstersii maybe be confused with Comamonas testosteroni using the automatic bacterial identification systems currently available. PATIENT CONCERNS: A 31-year-old man who had onset of left upper abdominal pain developed clinical manifestations of right lower abdominal pain and classic migration of pain at the temperature of 39 degrees C. The positive strain of aerobic and anaerobic bottles of blood cultures was identified. DIAGNOSES: The patient was diagnosed as acute peritonitis and perforated appendix with abdominal abscess. INTERVENTIONS: The bacterium was identified by routine methods, MALDI-TOF-MS and PCR amplification of the 16S rRNA. The patient was treated with exploratory laparotomy, appendectomy, tube drainage, and prescribing antibiotic treatment. OUTCOMES: The patients were discharged with complete recovery. The organisms were confirmed as C. kerstersii by MALDI-TOF-MS and a combination of the other results. LESSONS: Our findings suggest that C. kerstersii infection occurs most often in association with perforated appendix and bacteremia. We presume that C. kerstersii is an opportunistic pathogen or commensal with the digestive tract and appendix bacteria. PMID- 29595696 TI - Point-of-care ultrasound versus auscultation in determining the position of double-lumen tube. AB - This study was designed to assess the accuracy of point-of-care ultrasound in determining the position of double-lumen tubes (DLTs).A total of 103 patients who required DLT intubation were enrolled into the study. After DLTs were tracheal intubated in the supine position, an auscultation researcher and ultrasound researcher were sequentially invited in the operating room to conduct their evaluation of the DLT. After the end of their evaluation, fiberscope researchers (FRs) were invited in the operating room to evaluate the position of DLT using a fiberscope. After the patients were changed to the lateral position, the same evaluation process was repeated. These 3 researchers were blind to each other when they made their conclusions. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were obtained by statistical analysis.When left DLTs (LDLTs) were used, the accuracy of ultrasound (84.2% [72.1%, 92.5%]) was higher than the accuracy of auscultation (59.7% [45.8%, 72.4%]) (P < .01). When right DLTs (RDLTs) were used, the accuracy of ultrasound (89.1% [76.4%, 96.4%]) was higher than the accuracy of auscultation (67.4% [52.0%, 80.5%]) (P < .01). When LDLTs were used in the lateral position, the accuracy of ultrasound (75.4% [62.2%, 85.9%]) was higher than the accuracy of auscultation (54.4% [40.7%, 67.6%]) (P < .05). When RDLT were used, the accuracy of ultrasound (73.9% [58.9%, 85.7%]) was higher than the accuracy of auscultation (47.8% [32.9%, 63.1%]) (P < .05).Assessment via point-of-care ultrasound is superior to auscultation in determining the position of DLTs. PMID- 29595697 TI - Rare cardiac metastasis of soft tissue sarcoma: A case report and literature review. AB - RATIONALE: Owing to the unique structure and function of the heart, tumor metastasis in the heart is rare. Accordingly, no unique symptoms have yet been identified for cardiac metastasis. PATIENT AND CONCERNS: A patient presented with cardiac metastasis 3 years after surgical resection of alveolar soft tissue sarcomas in their late stage. DIAGNOSIS: Ultrasonography showed a middle-high echo clump on the left surface of the mid-upper interventricular septum, which had an unclear boundary with the myocardium. Meanwhile, blood flow was found in the clump, with no blockage of blood flow having been observed. LESSONS: Although cardiac metastasis in terminal cancer patients always carries a poor prognosis, there is still no effective treatment for cardiac metastasis. In the clinic, it is important to improve the patient's quality of life, reduce symptoms and signs, and extend the duration of survival. PMID- 29595698 TI - Identification of key genes and miRNAs associated with carotid atherosclerosis based on mRNA-seq data. AB - This study was aimed to explore the crucial genes and microRNAs (miRNAs) associated with the carotid atherosclerosis (CA).Two public datasets GSE28829 and GSE43292 were obtained from Gene Expression Omnibus databases to analyze the differentially expressed genes (DEGs) between primary and advanced atherosclerotic plaque tissues. The Gene Ontology (GO) terms, pathways, and protein-protein interactions (PPIs) of these DEGs were analyzed. miRNAs and transcription factor (TF) were predicted.A total of 112 upregulated and 179 downregulated intersection DEGs were identified between 2 datasets. In the PPI network, HSP90AB1 (degree = 19), RAP1A (degree = 14), and integrin subunit beta 1 (ITGB1) had higher degrees. A total of 23 miRNAs were predicted, such as miR-126, miR-155, miR-19A, and miR-19B. Four TFs were associated with upregulated DEGs, while 10 TFs were identified to be associated with downregulated genes.Our study suggests the important roles of HSP90AB1, RAP1A, and integrins proteins of ITGB1, ITGA11, ITGA9, and ITGB2 in the progression of CA plaque. Additionally, miR-126, miR-155, miR-19B, and miR-19A may be considered as biomarkers of CA. PMID- 29595699 TI - Severe bilateral isolated coronary ostial lesions as a rare manifestation of radiation-induced cardiac disease A case report. AB - RATIONALE: With advances in contemporary radiotherapy techniques, and as cancer survival improves, severe isolated coronary ostial disease may develop many years following mediastinal radiotherapy, even in the absence of classical cardiovascular risk factors. PATIENT CONCERNS: We describe the case of a 73-year old woman with previous chest radiotherapy for breast cancer who underwent coronary artery bypass graft surgery for severe bilateral coronary ostial lesions. DIAGNOSES: Coronary angiography demonstrated severe, isolated bilateral coronary ostial lesions. INTERVENTIONS: The patient underwent urgent coronary artery bypass graft surgery to treat her critical coronary artery disease. OUTCOMES: Intra-operatively, internal mammary arteries were not amenable to harvesting due to very dense mediastinal adhesions. Therefore, saphenous vein grafts were performed to the left anterior descending, distal left circumflex, obtuse marginal and distal right coronary arteries. The patient made a satisfactory in-hospital recovery, and was subsequently discharged back to her local hospital for rehabilitation. LESSONS: Patients successfully treated with mediastinal radiotherapy require careful long-term follow-up for the assessment of radiation-induced coronary artery disease. Importantly, mediastinal irradiation may preclude internal mammary artery utilization, and thus alter the strategy for surgical myocardial revascularization. PMID- 29595700 TI - Starting of biological disease modifying antirheumatic drugs may be postponed in rheumatoid arthritis patients with multimorbidity: Single center real life results. AB - The objective of this study was to assess the frequency of comorbidities and multimorbidities in rheumatoid arthritis (RA) patients under biologic therapy and their effects on biological disease modifying antirheumatic drugs (DMARDs) choice, timing, and response.Hacettepe University Biologic Registry (HUR-BIO) is single center biological DMARD registry. Cardiovascular, infectious, cancer, and other comorbidities were recorded with face to face interviews. Multimorbidity is defined as >1 comorbidity. Disease duration, initial date of biological DMARDs, initial and overall biological DMARD choice were recorded. Disease activity score 28 (DAS-28) responses were compared to comorbidity presence and multimorbidity.Total of 998 RA patients were enrolled into the study. The mean age was 53.1 (12.5) and mean disease duration (standard deviation [SD]) was 11.7 (7.5) years. At least 1 comorbidity was detected in 689 (69.1%) patients, 375 (37.9%) patients had multimorbidity. Patients had mean 1.36 +/- 1.32 comorbidity. The median durations of first biological DMARDs prescription were 60 (3-552) months after RA diagnosis. For multimorbidity patients, the median first biological prescription duration was longer than the duration for patients without multimorbidity (72 [3-552] vs 60 [3-396] months, P < .001). The physicians prescribe tumor necrosis factor inhibitor (TNFi) biological drugs less frequently than other biological DMARDs in patients with at least 1 comorbidity (66.2% vs 74.5%, P = .007) or multimorbidity (34.6% vs 43.5%, P = .006). Patients with comorbidities and multimorbidity achieved DAS-28 remission less frequently than patients without comorbidity (31.6% vs 42.6%, P = .012 and 27.2% vs 39.7%, P = .001, respectively).In real life, physicians may postpone to prescribe biological DMARDs and less frequently choose TNFi biological drugs in patients with multimorbidity. Furthermore, comorbidity may have a negative effect on the treatment response. PMID- 29595701 TI - A challenging diagnosis: Case report of oral metastasis from gastric adenocarcinoma mimicking pyogenic granuloma. AB - RATIONALE: Oral metastases occur more commonly in bone, but can also manifest in soft tissues and eventually resemble a reactive lesion. Few cases of oral metastases mimicking reactive lesions in soft tissues have been reported to date. PATIENT CONCERNS: We report a metastasis of gastric carcinoma (GC) to the oral mucosa without bone involvement in a 43 yom clinically and microscopically mimicking a reactive lesion. The patient related that the lesion had 1 month of evolution, and the ulcerated area suggested the lesion was related to trauma. DIAGNOSES: The histopathological examination of the lesion revealed an exuberant granulation tissue with few neoplastic cells, and the initial diagnosis of pyogenic granuloma was considered. In a second analysis, clusters of clear cells morphologically similar to degenerating mucous cells or macrophages, positive for Cytokeratin (CK)-20, and CDX2 were found. At the moment, it was confirmed the presence of a primary GC in the patient. INTERVENTIONS: A palliative radiotherapy/chemotherapy was started. OUTCOMES: However, the patient died 3 months after the diagnosis of oral metastasis. LESSONS: This report highlights the importance of careful clinical and microscopic examinations in cases of oral metastasis that may mimic a reactive lesion. PMID- 29595702 TI - Coinfection with 2 Clostridium difficile ribotypes in China: A case report. AB - RATIONALE: Clostridium difficile infections (CDIs) have been reported in China, but detailed clinical symptoms of coinfection by 2 C difficile ribotypes have not been documented. PATIENTS CONCERNS: An 83-year-old male with a 10-day history of diarrhea and urinary tract infection was admitted to the hospital. The patient had received ofloxacin for several days, but his clinical response was poor. Laboratory workup revealed high white blood cell (WBC), serum creatinine (Scr), and C-reactive protein (CRP) levels. Based on these abnormal lab results, rapid detection of glutamate dehydrogenase and toxin A and B was performed. DIAGNOSIS: Severe CDI. INTERVENTIONS: Oral vancomycin was administered for 8 days. OUTCOMES: Diarrhea symptoms improved and C difficile culture was negative after oral vancomycin administration for 8 days. Clostridium difficile was isolated from 3 consecutive stool samples at 2-day intervals because the patient was admitted to the hospital. Polymerase chain reaction ribotyping revealed ribotype (RT) 017 in the first 2 samples and RT 001 in the third sample. RT 017 caused significantly higher increases in the levels of WBC, Scr, and CRP than RT 001. LESSONS: It is necessary to improve clinicians' awareness of CDI and reduce the severity of CDI caused by RT 017 in China. PMID- 29595703 TI - The clinical result of arthroscopic bone grafting and percutaneous K-wires fixation for management of scaphoid nonunions. AB - The purpose of this study is to analyze the clinical results of patients with scaphoid nonunion treated with arthroscopic bone grafting and K (Kirschner)-wires fixation.We retrospectively reviewed the records of 27 patients with scaphoid nonunion who had been treated with arthroscopic bone grafting and K-wires fixation method from November 2008 to February 2014. The average patient age was 35 years. The time from injury to treatment averaged 45 months. The average follow-up period was 18 months. Bone union was assessed using serial plain radiographs. The functional outcome was evaluated by comparing the modified Mayo wrist score with the visual analog scale (VAS) for pain, which were measured at the time of preoperation and at final follow-up.Union was achieved in 26 of the 27 nonunions (96.29%). The average radiologic union time was 10 weeks. The average VAS score decreased from 6.38 (range, 3-10) preoperatively to 1.59 (range, 0-3) at the final follow-up. The average modified Mayo wrist score improved from 60.19 preoperatively to 83.46 at the final follow-up. According to this score, there were 12 excellent, 6 good, and 9 fair results at the final follow-up.Arthroscopic bone grafting and percutaneous K-wires fixation is an effective treatment method for a scaphoid nonunion and has the advantages of allowing thorough assessment, enabling a comprehensive management approach for scaphoid nonunion in a minimally invasive manner, and this method can also be used for the scaphoid nonunion with SNAC stage I. PMID- 29595704 TI - The role of 3D-printing technology in the diagnosis of Eagle syndrome: A case report. AB - RATIONALE: Eagle syndrome is a rare clinical condition that can be associated with elongation of the styloid process. PATIENT CONCERN: A 55-year-old man was presented with vague throat discomfort for several years. DIAGNOSIS: 3 dimentional (3D) computed tomography (CT) reconstruction, and printing revealed bilateral elongated styloid processes. INTERVENTIONS: The patient has been treated medically, and continues to demonstrate improvement with conservative treatment for 2 years. OUTCOME: We report usefulness of 3D CT and 3D printing technology for diagnosis of Eagle syndrome. LESSONS: 3D CT reconstruction, and printing are beneficial in determining appropriate surgical strategy, and allowing the physician to better explain the lesion, and surgical details to patients. PMID- 29595705 TI - Treatment of partial thickness hand burn injuries in children with combination of silver foam dressing and zinc-hyaluronic gel: Case reports. AB - RATIONALE: Burns is a common type of traumatic injury in childhood. Nowadays, several wound dressings are available to treat the second-degree hand burns conservatively. PATIENT CONCERNS, DIAGNOSES: At the authors' institute, 37 children were treated conservatively with a special dressing at first intervention containing Aquacel Ag foam and Zn-hyaluronic gel to determine their effectiveness on partial thickness hand burns. INTERVENTIONS: The dressing was checked on the second day, and removed on the sixth or seventh day (unless it had spontaneously separated). OUTCOMES: None of the 37 children treated with this dressing were diagnosed with wound infection. The authors observed the epithelialization of the burned areas on the 6-7th day after primary conservative treatment. The dressing efficiently promotes epithelialization in all cases. Further advantage of Zn-hyaluronic gel is to enhance cell regeneration and inhibits dressing fixation into the wound. LESSONS: Based on the authors' experience, with this special combination of wound dressing, a gentle, child friendly, cost-effective treatment and excellent wound healing observed with favourable cosmetic results. PMID- 29595706 TI - Large sliding inguino-scrotal hernia of the urinary bladder: A case report and literature review. AB - RATIONALE: Sliding inguinal hernias of the urinary bladder are protrusions of the bladder through the internal inguinal ring, most of which are insignificant and diagnosed intra-operatively. Large inguino-scrotal bladder hernias commonly present with lower urinary tract symptoms and may cause severe complications, including bladder incarceration or necrosis, bladder hemorrhage, obstructive or neurogenic bladder dysfunction, and even renal failure. PATIENT CONCERNS: We describe and discuss the clinical findings and management of a 59-year-old man who complained of a decrease in scrotal size after voiding and 2-stage voiding requiring pressure to the scrotum. DIAGNOSES: The patient was diagnosed preoperatively as massive, bilateral, inguinoscrotal hernias, and a large, left sided, sliding bladder hernia. INTERVENTIONS: The patient underwent a timely open re-peritoneal inguinal herniorrhaphy using a mesh. OUTCOMES: The surgical outcomes were good, and no surgical site infection, chronic postoperative inguinal pain or recurrence were recorded during the follow-up. LESSONS: Better knowledge of this rare condition of large inguino-scrotal sliding bladder hernia could help in making a correct diagnosis preoperatively and provide proper surgical management timely, so as to reduce delay in treatment and avoid potential complications. PMID- 29595707 TI - Enhancement of Meditation Analgesia by Opioid Antagonist in Experienced Meditators. AB - OBJECTIVE: Studies have consistently shown that long-term meditation practice is associated with reduced pain, but the neural mechanisms by which long-term meditation practice reduces pain remain unclear. This study tested endogenous opioid involvement in meditation analgesia associated with long-term meditation practice. METHODS: Electrical pain was induced with randomized, double-blind, cross-over administration of the opioid antagonist naloxone (0.15-mg/kg bolus dose, then 0.2-mg/kg per hour infusion dose) with 32 healthy, experienced meditation practitioners and a standardized open monitoring meditation. RESULTS: Under saline, pain ratings were significantly lower during meditation (pain intensity: 6.41 +/- 1.32; pain unpleasantness: 3.98 +/- 2.17) than at baseline (pain intensity: 6.86 +/-1.04, t(31) = 2.476, p = .019, Cohen's d = 0.46; pain unpleasantness: 4.96 +/-1.75, t(31) = 3.746, p = .001, Cohen's d = 0.68), confirming the presence of meditation analgesia. Comparing saline and naloxone revealed significantly lower pain intensity (t(31) = 3.12, p = .004, d = 0.56), and pain unpleasantness (t(31) = 3.47, p = .002, d = 0.62), during meditation under naloxone (pain intensity: 5.53 +/- 1.54; pain unpleasantness: 2.95 +/- 1.88) than under saline (pain intensity: 6.41 +/- 1.32; pain unpleasantness: 3.98 +/- 2.17). Naloxone not only failed to eliminate meditation analgesia but also made meditation analgesia stronger. CONCLUSIONS: Long-term meditation practice does not rely on endogenous opioids to reduce pain. Naloxone's blockade of opioid receptors enhanced meditation analgesia; pain ratings during meditation were significantly lower under naloxone than under saline. Possible biological mechanisms by which naloxone-induced opioid receptor blockade enhances meditation analgesia are discussed. PMID- 29595708 TI - Brain-Heart Pathways to Blood Pressure-Related Hypoalgesia. AB - OBJECTIVE: High blood pressure (BP) is associated with reduced pain sensitivity, known as BP-related hypoalgesia. The underlying neural mechanisms remain uncertain, yet arterial baroreceptor signaling, occurring at cardiac systole, is implicated. We examined normotensives using functional neuroimaging and pain stimulation during distinct phases of the cardiac cycle to test the hypothesized neural mediation of baroreceptor-induced attenuation of pain. METHODS: Eighteen participants (10 women; 32.7 (6.5) years) underwent BP monitoring for 1 week at home, and individual pain thresholds were determined in the laboratory. Subsequently, participants were administered unpredictable painful and nonpainful electrocutaneous shocks (stimulus type), timed to occur either at systole or at diastole (cardiac phase) in an event-related design. After each trial, participants evaluated their subjective experience. RESULTS: Subjective pain was lower for painful stimuli administered at systole compared with diastole, F(1, 2283) = 4.82, p = 0.03. Individuals with higher baseline BP demonstrated overall lower pain perception, F(1, 2164) = 10.47, p < .0001. Within the brain, painful stimulation activated somatosensory areas, prefrontal cortex, cingulate cortex, posterior insula, amygdala, and the thalamus. Stimuli delivered during systole (concurrent with baroreceptor discharge) activated areas associated with heightened parasympathetic drive. No stimulus type by cardiac phase interaction emerged except for a small cluster located in the right parietal cortex. CONCLUSIONS: We confirm the negative associations between BP and pain, highlighting the antinociceptive impact of baroreceptor discharge. Neural substrates associated with baroreceptor/BP-related hypoalgesia include superior parietal lobule, precentral, and lingual gyrus, regions typically involved in the cognitive aspects of pain experience. PMID- 29595709 TI - Neural, Hormonal, and Cognitive Correlates of Metabolic Dysfunction and Emotional Reactivity. AB - OBJECTIVE: Prediabetes and type 2 diabetes (i.e., hyperglycemia) are characterized by insulin resistance. These problems with energy metabolism may exacerbate emotional reactivity to negatively valenced stimuli and related phenomena such as predisposition toward negative affect, as well as cognitive deficits. Higher emotional reactivity is seen with hyperglycemia and insulin resistance. However, it is largely unknown how metabolic dysfunction correlates with related neural, hormonal, and cognitive outcomes. METHODS: Among 331 adults from the Midlife in the United States study, eye-blink response (EBR) we cross sectionally examined to gauge reactivity to negative, positive, or neutrally valenced pictures from international affect picture system stimuli proximal to an acoustic startle probe. Increased EBR to negative stimuli was considered an index of stress reactivity. Frontal alpha asymmetry, a biomarker of negative affect predisposition, was determined using resting electroencephalography. Baseline urinary cortisol output was collected. Cognitive performance was gauged using the Brief Test of Adult Cognition by telephone. Fasting glucose and insulin characterized hyperglycemia or the homeostatic model assessment of insulin resistance. RESULTS: Higher homeostatic model assessment of insulin resistance corresponded to an increased startle response, measured by EBR magnitude, for negative versus positive stimuli (R = 0.218, F(1,457) = 5.48, p = .020, euglycemia: M(SD) = .092(.776), hyperglycemia: M(SD) = .120(.881)). Participants with hyperglycemia versus euglycemia showed greater right frontal alpha asymmetry (F(1,307) = 6.62, p = .011, euglycemia: M(SD) = .018(.167), hyperglycemia: M(SD) = -.029(.160)), and worse Brief Test of Adult Cognition by telephone arithmetic performance (F(1,284) = 4.25, p = .040, euglycemia: M(SD) = 2.390(1.526), hyperglycemia: M(SD) = 1.920(1.462)). Baseline urinary cortisol (log10 MUg/12 hours) was also dysregulated in individuals with hyperglycemia (F(1,324) = 5.09, p = .025, euglycemia: M(SD) = 1.052 +/- .332, hyperglycemia: M(SD) = .961 (.362)). CONCLUSIONS: These results suggest that dysmetabolism is associated with increased emotional reactivity, predisposition toward negative affect, and specific cognitive deficits.

PMID- 29595710 TI - Cardiovascular Risk Factors as Differential Predictors of Incident Atypical and Typical Major Depressive Disorder in US Adults. AB - OBJECTIVE: Although the association between major depressive disorder (MDD) and future cardiovascular disease (CVD) is established, less is known about the relationship between CVD risk factors and future depression, and no studies have examined MDD subtypes. Our objective was to determine whether hypertension, tobacco use, and body mass index (BMI) differentially predict atypical and typical MDD in a national sample of US adults. METHODS: We examined prospective data from 22,915 adults with no depressive disorder history at baseline who participated in Wave 1 (2001-2002) and Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. CVD risk factors (Wave 1) and incident MDD subtypes (Wave 2) were determined by structured interviews. RESULTS: There were 252 patients with atypical MDD and 991 patients with typical MDD. In fully adjusted models, baseline hypertension (odds ratio [OR] = 0.57, 95% confidence interval [CI] = 0.43-0.76), former tobacco use (OR = 1.46, 95% CI = 1.20-1.78), and BMI (OR = 1.32, 95% CI = 1.25-1.40; all p < .001) predicted incident atypical MDD versus no MDD, whereas no CVD risk factor predicted incident typical MDD. Baseline hypertension (OR = 0.52, 95% CI = 0.39-0.70), former tobacco use (OR = 1.53, 95% CI = 1.22-1.93), and BMI (OR = 1.26, 95% CI = 1.18-1.36; all p < .001) also predicted incident atypical MDD versus typical MDD. CONCLUSIONS: Our study is the first to report that CVD risk factors differentially predict MDD subtypes, with hypertension (protective factor), former tobacco use (risk factor), and BMI (risk factor) being stronger predictors of incident atypical versus typical MDD. Such evidence could provide insights into the etiologies of MDD subtypes and inform interventions tailored to MDD subtype.

PMID- 29595713 TI - Introduction to "Sientra Shaped and Round Cohesive Gel Implants: Long-Term Safety Outcomes". PMID- 29595714 TI - Ten-year Core Study Data for Sientra's Food and Drug Administration-Approved Round and Shaped Breast Implants with Cohesive Silicone Gel. AB - BACKGROUND: In March 2012, the United States Food and Drug Administration approved Sientra's application for premarket approval of its portfolio of round and shaped silicone gel breast implants based on data from the largest silicone gel breast implant study to date. This article presents the results of Sientra's Core Study at the conclusion of 10 years. METHODS: The Sientra Core Study was a 10-year, open-label, prospective, multicenter clinical study designed to assess the safety and effectiveness of Sientra's breast implants in augmentation and reconstruction. A total of 1,788 patients (3,506 implants) were enrolled, including 1,116 primary augmentation, 363 revision-augmentation, 225 primary reconstruction, and 84 revision-reconstruction. RESULTS: Across all cohorts, the rate of rupture by patient was 8.6%, the rate of Baker grade III/IV capsular contracture was 13.5%, and the rate of reoperation was 31.5%. The rate of capsular contracture was statistically significantly lower for textured devices [9.0%; 95% confidence interval (CI), 7.0-11.5%] compared with smooth devices (17.5%; 95% CI, 14.9-20.4%). There were no cases of breast implant-associated anaplastic large cell lymphoma. Primary reasons for reoperations included capsular contracture (18.8%), and style/size change (19.3%), with over 50% of the reoperations due to cosmetic reasons. CONCLUSION: The 10-year results of Sientra's Core Study support a comprehensive safety and effectiveness profile of Sientra's portfolio of round and shaped breast implants. PMID- 29595715 TI - Risk Factor Analysis for Capsular Contracture: A 10-Year Sientra Study Using Round, Smooth, and Textured Implants for Breast Augmentation. AB - BACKGROUND: Despite the increased understanding of surgical best practices, capsular contracture remains the most commonly reported complication and reason for reoperation following breast implant surgery. This study provides a long-term update to a previous investigation of potential contributing risk factors for capsular contracture in primary augmentation patients. METHODS: The data used for this analysis include 5,122 implants in 2,565 primary augmentation patients implanted by 34 surgeons based on long-term results from Sientra's clinical study. Potential risk factors, including patient and implant attributes, surgery characteristics, pocket irrigation, and postsurgery characteristics, were analyzed using frequency and multivariate models. RESULTS: A total of 333 capsular contracture events in 224 patients were reported. The overall Kaplan Meier rate for capsular contracture was 10.8% by device through 10 years. Results from the multivariate analysis found 8 factors to be independently associated with capsular contracture (implant placement, implant surface, incision site, hematoma or seroma development, device size, surgical bra, steroid, and antibiotic pocket irrigation; all P values < 0.05). Results from correlation analysis found 2 of the 8 factors to be more strongly associated with early onset capsular contracture events, compared with those occurring after 2 and 5 years of implantation (implant surface and steroid pocket irrigation). CONCLUSION: The results of this large-scale, multivariate analysis identified several significant risk factors for capsular contracture, including device features (smooth surface, smaller size), surgical factors (periareolar incision, subglandular placement, antibiotic irrigation), the development of hematoma/seroma, and the use of a surgical bra. PMID- 29595716 TI - Sientra AlloX2 Short-Term Case Study, Surgical Pearls, and Roundtable Discussion. AB - BACKGROUND: The AlloX2 Breast Tissue Expander (Sientra, Santa Barbara, Calif.) is a unique device that contains a second port to allow for transdermal communication with the pocket around the implant. The injection dome of this expander contains two ports; one is used for traditional saline injection, and a new second port facilitates fluid drainage from the periprosthetic space through an integral drain. The AlloX2 allows for the treatment of seromas and diagnostic fluid sampling to identify bacteria and hone antibiotic treatment in the setting of periprosthetic infection. This device has a significant advantage over traditional expanders, given that seromas and infections are the most common complications in implant-based breast reconstruction, with or without the use of soft-tissue support matrix. METHODS: This article provides short-term case studies and surgical pearls from 3 surgeons who utilize the AlloX2 in primary breast reconstruction patients. Three surgeons implanted 40 primary reconstruction patients with AlloX2. Follow-up was approximately 6 months, per the standard of care. All patients implanted with AlloX2 underwent immediate reconstruction, with the exception of 1 delayed reconstruction. RESULTS: The most common complications the patients experienced were seromas. In most cases, the surgeons successfully used the second port to drain periprosthetic fluid. CONCLUSIONS: The AlloX2 has been successful in treating seromas and should be considered a tool for noninvasive treatment of common complications of implant based breast reconstruction. Three surgeons with varied backgrounds and techniques provide their surgical and postoperative management experiences and recommendations. PMID- 29595717 TI - Results of the Postmarket Clinical Study of the Sientra 207 Highly Cohesive Gel Breast Implants in Primary and Revision Augmentation. AB - BACKGROUND: Board-certified plastic surgeons utilizing the Sientra 207 Highly Cohesive Gel breast implants provided their initial satisfaction with usage and postoperative results on primary and revision augmentation patients, and study participants provided their satisfaction with surgical result. METHODS: Up to 15 participating investigators at institutional review board-approved sites enrolled up to 180 women who received Sientra 207 implants for primary augmentation or revision augmentation procedures. Investigator and participant assessments were performed preoperatively and postoperatively at 3, 6, and 12 months. RESULTS: All participating surgeons found the implants to be easy or very easy to implant, and 92 percentage reported satisfaction with surgical results. Patients receiving these implants reported similarly high rates of satisfaction (94%). CONCLUSION: With this combination of high satisfaction and low complication rates, the Sientra 207 silicone breast implants now provide a welcome addition to plastic surgeons' breast implant options. PMID- 29595718 TI - Breast Cancer following Augmentation Mammaplasty: A Case-Control Study. AB - BACKGROUND: The purpose of this study was to determine whether augmentation mammaplasty, implant type, and implant location affect breast cancer detection, stage, and treatment. METHODS: An institutional case-control study was performed of patients with prior breast augmentation undergoing breast cancer treatment from 2000 to 2013. Controls were propensity matched and randomized, and data were retrospectively reviewed. RESULTS: Forty-eight cases and 302 controls were analyzed. Palpable lesions were detected at a smaller size in augmentation patients (1.6 cm versus 2.3 cm; p < 0.001). Fewer lesions in augmented patients were detected by screening mammography (77.8 percent of cases versus 90.7 percent of controls; p = 0.010). Patients with implants were more likely to undergo an excisional biopsy for diagnosis (20.5 percent versus 4.4 percent; p < 0.001), rather than image-guided core needle biopsy (77.3 percent versus 95.3 percent; p < 0.001). Earlier staging in augmented patients approached but did not reach statistical significance (p = 0.073). Augmented patients had higher mastectomy rates (74.5 percent versus 57.0 percent) and lower rates of breast-conservation therapy (25.5 percent versus 43 percent; p = 0.023). Neither implant fill type nor anatomic location affected method of diagnosis, stage, or treatment. CONCLUSIONS: Palpable detection of breast cancer is more likely at a smaller size in augmented patients, yet it is less likely on screening mammography than in controls. Augmentation breast cancer patients have a comparable disease stage and are more likely to undergo mastectomy rather than lumpectomy. Both silicone and saline implants, whether placed submuscularly or subglandularly, have comparable effects on breast imaging, biopsy modality, and surgical intervention. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29595719 TI - Discussion: Enhanced Recovery Pathway in Microvascular Autologous Tissue-Based Breast Reconstruction: Should It Become the Standard of Care? PMID- 29595720 TI - 5000 Free Flaps and Counting: A 10-Year Review of a Single Academic Institution's Microsurgical Development and Outcomes. AB - BACKGROUND: The establishment of an effective clinical and academic culture within an institution is a multifactorial process. This process is cultivated by dynamic elements such as recruitment of an accomplished and diverse faculty, patient geographic outreach, clinical outcomes research, and fundamental support from all levels of an institution. This study reviews the academic evolution of a single academic plastic surgery practice, and summarizes a 10-year experience of microsurgical development, clinical outcomes, and academic productivity. METHODS: A 10-year retrospective institutional review was performed from fiscal years 2006 to 2016. Microsurgical flap type and operative volume were measured across all microsurgery faculty and participating hospitals. Microvascular compromise and flap salvage rates were noted for the six highest volume surgeons. Univariate and multivariable predictors of flap salvage were determined. RESULTS: The 5000th flap was performed in December of 2015 within this institutional study period. Looking at the six highest volume surgeons, free flaps were examined for microvascular compromise, with an institutional mean take-back rate of 1.53 percent and flap loss rate of 0.55 percent across all participating hospitals. Overall, 74.4 percent of cases were breast flaps, and the remaining cases were extremity and head and neck flaps. CONCLUSIONS: Focused faculty and trainee recruitment has resulted in an academically and clinically productive practice. Collaboration among faculty, staff, and residents contributes to continual learning, innovation, and quality patient care. This established framework, constructed based on experience, offers a workable and reproducible model for other academic plastic surgery institutions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29595721 TI - Trends in Physician Payments for Breast Reconstruction. AB - BACKGROUND: Prosthetic breast reconstruction rates have risen in the United States, whereas autologous techniques have stagnated. Meanwhile, single institution data demonstrate that physician payments for prosthetic reconstruction are rising, while payments for autologous techniques are unchanged. This study aims to assess payment trends and variation for tissue expander and free flap breast reconstruction. METHODS: The Blue Health Intelligence database was queried from 2009 to 2013, identifying women with claims for breast reconstruction. Trends in the incidence of surgery and physician reimbursement were characterized by method and year using regression models. RESULTS: There were 21,259 episodes of breast reconstruction, with a significant rise in tissue expander cases (incidence rate ratio, 1.09; p < 0.001) and an unchanged incidence of free flap cases (incidence rate ratio, 1.02; p = 0.222). Bilateral tissue expander cases reimbursed 1.32 times more than unilateral tissue expanders, whereas bilateral free flaps reimbursed 1.61 times more than unilateral variants. The total growth in adjusted tissue expander mean payments was 6.5 percent (from $2232 to $2378) compared with -1.8 percent (from $3858 to $3788) for free flaps. Linear modeling showed significant increases for tissue expander reimbursements only. Surgeon payments varied more for free flaps (the 25th to 75th percentile interquartile range was $2243 for free flaps versus $987 for tissue expanders). CONCLUSIONS: The incidence of tissue expander cases and reimbursements rose over a period where the incidence of free flap cases and reimbursements plateaued. Reasons for stagnation in free flaps are unclear; however, the opportunity cost of performing this procedure may incentivize the alternative technique. Greater payment variation in autologous reconstruction suggests the opportunity for negotiation with payers. PMID- 29595722 TI - Comparison of Cartilage-Scoring and Cartilage-Sparing Otoplasty: A Retrospective Analysis of Complications and Aesthetic Outcome of 1060 Ears. AB - BACKGROUND: Various techniques are used to correct prominent ears. The authors describe their experience with four different otoplasty techniques in 565 patients with congenital deformities of the ears (1060 ears) that were performed in their hospital during an 11-year period (2002 to 2012). METHODS: The authors divided the techniques into two groups: group I, cartilage-sparing techniques (i.e., IA, Mustarde; and IB, Furnas); and group II, cartilage-cutting techniques (i.e., IIA, Chongchet; and IIB, concha shell reduction). The authors compared early and late and minor and major complications, recurrence rates, and revision surgery. Furthermore, aesthetic outcome was scored by three different groups (consultant plastic surgeons, plastic surgery residents, and laymen) on a visual analogue scale using a blinded random selection of preoperative and postoperative photographs. RESULTS: The percentage of complications without the need for reoperation was 20 percent and 21 percent in the cartilage-sparing and cartilage cutting groups, respectively (p = 0.44). In 6 percent of all cases, a reoperation of the otoplasty was required (7 percent and 6 percent in the cartilage-sparing and cartilage-cutting groups, respectively). Aesthetic postoperative results showed that the cartilage-cutting group scored significantly lower on postoperative shape (p = 0.04), result (p = 0.03), and satisfaction (p = 0.04) compared with the cartilage-sparing group. CONCLUSIONS: The study shows that patients who have undergone operations with cartilage-sparing or cartilage cutting techniques have a similar rate of complications and need for reoperation. However, the cartilage-sparing techniques have a better aesthetic outcome, as judged by the different groups. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29595723 TI - Inner Scar Umbilicus: New Horizons for Vertical Abdominoplasty. AB - BACKGROUND: It is reasonable that deflated tissue in massive weight loss patients may demand not only lifting but also some extent of central body tightening, by the fleur-de-lis procedure. Although achieving nice contouring results, poor visible scars, including umbilical complications, have restricted the indications for the anterior vertical approach. The purpose of this article is to present the authors' experience with the inner scar umbilical reconstruction, reflecting overall results in vertical abdominoplasties. METHODS: Massive weight loss patients who underwent fleur-de-lis abdominoplasties with the inner scar umbilicus were reviewed retrospectively. The original stalk was resected along with the surgical specimen, and two marked parallel skin flaps were kept and sutured against each other into the deep medial fascia, to reconstruct the umbilical base. Additional sutures were made to approximate fat tissue immediately under and above it, enhancing a deepening effect. Conventional upper and lower vertical closure helped to establish the tridimensional shape of the new navel. RESULTS: One hundred ten consecutive patients were studied, and 52 (47 percent) presented small inflammatory exudate arising from the inner suture, which resolved with conservative dry dressings. No further umbilical complications such as infection, necrosis, dehiscence, widening, or stenosis were reported, and all patients showed natural and scarless new navels with nice shapes and correct position. CONCLUSIONS: The inner scar umbilicus is a simple, safe, and reproducible technique, presenting low complication rates with sustainable and natural results. High-quality navel reconstruction favors the indication of vertical abdominoplasties, especially for post-bariatric surgery body contouring. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29595724 TI - An Update on the Safety and Efficacy of Outpatient Plastic Surgery: A Review of 26,032 Consecutive Cases. AB - BACKGROUND: Outpatient surgery offers many advantages, including cost containment, privacy, and convenience. However, patient safety must take precedence over these benefits. Limited well-designed studies exist in the plastic surgery literature on patient safety in the outpatient setting, particularly those that identify risk factors for adverse outcomes. METHODS: A retrospective review was performed on 26,032 consecutive cases completed by board certified plastic surgeons at an accredited outpatient surgical center between 1995 and 2017. All cases were reviewed for potential morbidity and mortality events, and variables were analyzed to determine potential risk factors for postoperative complications and inpatient admission. RESULTS: A total of 26,032 cases were performed over a 23-year period. There were a total of 203 complications (0.78 percent). Compared with the control population, the 12 patients (0.05 percent) that sustained venous thromboembolic events demonstrated higher body mass indexes (p < 0.01), greater lipoaspirate amounts (p = 0.04), longer operative times (p < 0.01), and were more likely to have undergone a combined procedure (p < 0.01). In addition, the 22 patients (0.08 percent) that were transferred to inpatient facilities demonstrated greater body mass index (p < 0.01) and longer operative times (p = 0.01). CONCLUSIONS: Plastic surgery is safe to perform in an accredited outpatient facility for a majority of patients. According to the authors' data, postoperative monitoring in a nursing facility should be considered for the following high-risk patients: those with a body mass index greater than 30 kg/m, operative times greater than 4 hours, lipoaspirate volumes greater than 3 liters, and those undergoing combined procedures. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 29595725 TI - Plastic Surgery Complications from Medical Tourism Treated in a U.S. Academic Medical Center. AB - BACKGROUND: Medical tourism is a growing, multi-billion dollar industry fueled by improvements in the global transportation infrastructure. The authors studied patients living in the United States who travel to other countries for plastic surgical procedures and returned to have their complications treated in the authors' center. METHODS: A retrospective patient evaluation was performed. Patients who had presented to an urban tertiary academic hospital plastic surgery service with complications or complaints associated with plastic surgery performed in a developing country were studied. The authors collected demographic information, types of surgery performed, destinations, insurance coverage, and complications. RESULTS: Seventy-eight patients were identified over 7 years. Most commonly, complications were seen following abdominoplasty (n = 35), breast augmentation (n = 25), and foreign body injections (n = 15). Eighteen patients underwent multiple procedures in one operative setting. The most common destination country was the Dominican Republic (n = 59). Complications included surgical-site infections (n = 14), pain (n = 14), and wound healing complications (n = 12). Eighty-six percent of patients (n = 67) relied on their medical insurance to pay for their follow-up care or manage their complications, with the most common type of health insurance coverage being Massachusetts Medicaid (n = 48). CONCLUSIONS: Cosmetic surgery performed in developing countries can carry substantial risks of complications that can be challenging to patients, primary care providers, insurers, and plastic surgical teams not associated with the original surgery. These complications pose significant burdens on our public health systems.

AB - BACKGROUND: In late presentation of brachial plexus trauma, it is unclear whether donor nerves should be devoted to nerve reconstruction or reserved for free functional muscle transfer. The authors systematically reviewed recovery of elbow flexion after nerve reconstruction versus free functional muscle transfer for late, traumatic brachial plexus palsy. METHODS: A systematic review was performed using the PubMed, Embase, and Cochrane databases to identify all cases of traumatic brachial plexus palsy in patients aged 18 years or older. Patients who underwent late (>=12 months) nerve reconstruction or free functional muscle transfer for elbow flexion were included. Age, time to operation, and level of brachial plexus injury were recorded. British Medical Research Council grade for strength and range of motion were evaluated for elbow flexion. RESULTS: Thirty three studies met criteria, for a total of 103 patients (nerve reconstruction, n = 53; free functional muscle transfer, n = 50). There were no differences across groups regarding surgical age (time from injury) and preoperative elbow flexion. For upper trunk injuries, 53 percent of reconstruction patients versus 100 percent of muscle transfer patients achieved grade M3 or greater strength, and 43 percent of reconstruction patients versus 70 percent of muscle transfer patients achieved grade M4 or greater strength. Of the total brachial plexus injuries, 37 percent of reconstruction patients versus 78 percent of muscle transfer patients achieved grade M3 or greater strength, and 16 percent of reconstruction patients versus 46 percent of muscle transfer patients achieved grades M4 or greater strength. CONCLUSION: In late presentation of traumatic brachial plexus injuries, donor nerves should be reserved for free functional muscle transfer to restore elbow flexion. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29595731 TI - Augmentation of the Median Tubercle with Dermis-Fat Graft in Children with Repaired Cleft Lip. AB - BACKGROUND: Deficiency of the median tubercle is a common residual deformity after repair of cleft lip. The purpose of this study was to analyze the change in labial contour after insertion of a dermis-fat graft. METHODS: Patients with repaired cleft lip who underwent secondary dermis-fat grafting of the median tubercle between 2012 and 2015, along with preoperative and greater than or equal to 3-month postoperative three-dimensional photographs, were included. The photographs were registered to one another and measurements made before and after grafting using anthropometric landmarks. Outcome variables included the following: labial surface area, midline labial height (ls-sto), and lateral labial height (cphi-sto'). RESULTS: Twenty-five patients were included: 14 with unilateral and 11 with bilateral repaired cleft lip. Mean age at graft placement was 10.9 +/- 3.2 years. Preoperative and postoperative three-dimensional images were taken at 13.6 +/- 21.6 weeks before and 34.8 +/- 25.1 weeks after the procedure, respectively. There were significant increases in labial surface area (11.5 percent; p = 0.019) and labial height (14.1 to 18.5 percent; p = 0.002) after grafting. Augmentation was greater in bilateral clefts (25.5 percent at midline and 16.8 percent laterally) compared with unilateral clefts (11.6 percent at midline and 12.5 percent on the grafted noncleft side). Intrarater and interrater reliability was excellent for all measurements. CONCLUSION: Dermis-fat grafting significantly increases contour of the median tubercle in patients with repaired cleft lip. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29595732 TI - Outcome of Palate Re-repair with Radical Repositioning of the Levator Muscle Sling as a First-Line Strategy in Postpalatoplasty Velopharyngeal Incompetence Management Protocol. AB - BACKGROUND: Palatal re-repair aims to improve velar function by retropositioning the levator muscles. Although it has become a popular procedure, very few studies document its efficacy. To date, this is the largest series reported to clarify its indications and efficacy. METHODS: One hundred eighty-three consecutive cleft patients presenting with velopharyngeal incompetence and evidence of abnormally oriented levator muscles underwent palate re-repair (regardless of the gap size) performed by a single surgeon from 2000 to 2015. Perceptual speech assessment was performed using the Pittsburgh Weighted Speech Score. Other patients' demographic data were collected. RESULTS: Complete records of 111 patients were available. Eighteen cases were syndromic (18.9 percent). Postoperatively, there was highly significant improvement (p < 0.001) in nasal emission (from 2.24 to 0.64), nasality (from 3.44 to 1.27), articulation (from 5.32 to 2.01), and total score (from 11.29 to 4.11). Speech became normal/borderline normal, improved or did not improve in 66.7, 24.3, and 9 percent of patients, respectively. An initial diagnosis of isolated cleft palate, Caucasians, intravelar veloplasty in the primary repair, older patients, and nonsyndromic cases were associated with better outcome. There were no reported cases of postoperative fistula or new obstructive sleep apnea. CONCLUSIONS: This large series study provides confirmatory evidence of the effectiveness and safety of the re-repair procedure. It is recommended as a first-line procedure in all velopharyngeal incompetence cases with abnormally oriented levator muscles regardless of gap size, even if the primary operation included prior muscle dissection. The pharyngoplasty rate could be significantly reduced with the current protocol. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID- 29595733 TI - Predictors for Unfavorable Projection of the Constructed Auricle following Ear Elevation Surgery in Microtia Reconstruction. AB - BACKGROUND: Nagata's two-stage technique for microtia reconstruction using autologous costal cartilage consists of the implantation of a fabricated cartilage framework and the elevation of the constructed auricle. Achieving long lasting, sufficient projection of the auricle is a goal of second-stage surgery; however, unfavorable outcomes have been seen in some patients, with suboptimal long-term elevation. The present study aimed to investigate prognostic factors that might contribute to adverse outcomes following the ear elevation operation. METHODS: Outcomes of patients with congenital microtia who underwent auricular reconstruction with a modified Nagata technique between January of 2007 and June of 2015 were reviewed. Unfavorable elevation was defined as cases with an auriculocephalic angle less than 20 degrees or with a shallow auricular sulcus requiring revision operations. Univariate and multivariate analyses were conducted to identify independent predictors for the unfavorable elevation. RESULTS: A total of 309 patients representing 323 cases were analyzed with a median follow-up period of 26 months. The mean age of the patients was 15.1 years. The majority of cases had lobule-type microtia. Hemifacial microsomia was present in 114 cases. Canalplasty was performed in 117 cases before the auricular elevation. Unfavorable elevation was observed in 72 cases (22.3 percent). Multivariate analyses showed that the presence of hemifacial microsomia and performance of canalplasty less than or equal to 12 months before the ear elevation operation were independent risk factors for the unfavorable elevation. CONCLUSION: Several preoperative factors, including combined anomalies and operative timing and sequences, might influence the outcomes of the ear elevation operation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 29595734 TI - Incidence of Cranial Base Suture Fusion in Infants with Craniosynostosis. AB - BACKGROUND: Cranial base sutures are important drivers of both facial and cranial growth. The purpose of this study was to compare the incidence and location of cranial base suture fusion among three groups: nonaffected controls, patients with nonsyndromic craniosynostosis, and patients with syndromic craniosynostosis. METHODS: Patients and computed tomographic scans were accrued from the authors' prospective craniofacial database. Computed tomographic scans were graded on the frequency of cranial vault and cranial base suture/synchondrosis fusion (0, open; 1, partially/completely fused) by an attending craniofacial surgeon and neuroradiologist. Statistical comparisons were conducted on location and rates of fusion, age, and diagnosis. RESULTS: One hundred forty patients met inclusion criteria: 55 syndromic, 64 nonsyndromic, and 21 controls. Average age at computed tomography of syndromic patients (3.6 +/- 3.1 months) was younger than that of nonsyndromic patients (5.4 +/- 3.1 months; p = 0.001) and control subjects (5.1 +/- 3.2 months; p = 0.058). Syndromic craniosynostotic patients had over three times as many cranial base minor sutures fused (2.2 +/- 2.5) as nonsyndromic craniosynostosis patients (0.7 +/- 1.2; p < 0.001) and controls (0.4 +/- 0.8; p = 0.002), whose rates of fusion were statistically equivalent (p = 0.342). Syndromic craniosynostosis patients had a greater frequency of cranial base suture fusion in the coronal branches, squamosal arch, and posterior intraoccipital synchondrosis (p < 0.05). CONCLUSIONS: Patients with syndromic craniosynostosis have higher rates of cranial base suture fusion in infancy, especially in the coronal arches, and this may have significant implications for both cranial and facial growth. In contrast, patients with nonsyndromic craniosynostosis have similar rates and sites of cranial base suture fusion as controls. Interestingly, there is a low, "normal," rate of cranial base suture/synchondrosis closure in infancy, the implications of which are unknown. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III. PMID- 29595735 TI - A New Composite Eyeball-Periorbital Transplantation Model in Humans: An Anatomical Study in Preparation for Eyeball Transplantation. AB - BACKGROUND: Vascularized composite allotransplantation offers a new hope for restoration of orbital content and perhaps vision. The aim of this study was to introduce a new composite eyeball-periorbital transplantation model in fresh cadavers in preparation for composite eyeball allotransplantation in humans. METHODS: The composite eyeball-periorbital transplantation flap borders included the inferior border, outlined by the infraorbital rim; the medial border, created by the nasal dorsum; the lateral border, created by the lateral orbital rim; and the superior border, created by the superior part of the eyebrow. The pedicle of the flap included the facial artery, superficial temporal artery, and external jugular vein. The skin and subcutaneous tissues of the periorbital region were dissected and the bony tissue was reached. A coronal incision was performed and the frontal lobe of the brain was reached by means of frontal osteotomy. Ophthalmic and oculomotor nerves were also included in the flap. After a "box osteotomy" around the orbit, the dissection was completed. Methylene blue and indocyanine green injection (SPY Elite System) was performed to show the integrity of the vascular territories after facial flap harvest. RESULTS: Adequate venous return was observed within the flap after methylene blue dye injection. Laser-assisted indocyanine green angiography identified a well-defined vascular network within the entire composite eyeball-periorbital transplantation flap. CONCLUSIONS: For the first time, a novel composite eyeball-periorbital transplantation model in human cadavers was introduced. Good perfusion of the flap confirmed the feasibility of composite eyeball-periorbital transplantation in the clinical setting. Although harvesting of the flap is challenging, it introduces a new option for reconstruction of the periorbital region including the eyeball. PMID- 29595736 TI - Cranial Nerve Coactivation and Implication for Nerve Transfers to the Facial Nerve. AB - In reanimation surgery, effortless smile can be achieved by a nonfacial donor nerve. The underlying mechanisms for this smile development, and which is the best nonfacial neurotizer, need further clarification. The aim of the present study was therefore to further explore the natural coactivation between facial mimic muscles and muscles innervated by the most common donor nerves used in smile reanimation. The study was conducted in 10 healthy adults. Correlation between voluntary facial muscle movements and simultaneous electromyographic activity in muscles innervated by the masseter, hypoglossal, and spinal accessory nerves was assessed. The association between voluntary movements in the latter muscles and simultaneous electromyographic activity in facial muscles was also studied. Smile coactivated the masseter and tongue muscles equally. During the seven mimic movements, the masseter muscle had fewer electromyographically measured coactivations compared with the tongue (two of seven versus five of seven). The trapezius muscle demonstrated no coactivation during mimic movements. Movements of the masseter, tongue, and trapezius muscles induced electromyographically recorded coactivation in the facial muscles. Bite resulted in the strongest coactivation of the zygomaticus major muscle. The authors demonstrated coactivation between voluntary smile and the masseter and tongue muscles. During voluntary bite, strong coactivation of the zygomaticus major muscle was noted. The narrower coactivation pattern in the masseter muscle may be advantageous for central relearning and the development of a spontaneous smile. The strong coactivation between the masseter muscle and the zygomaticus major indicates that the masseter nerve may be preferred in smile reanimation. PMID- 29595737 TI - Surgical Approach to Injuries of the Cervical Plexus and Its Peripheral Nerve Branches. AB - BACKGROUND: Located in the neck beneath the sternocleidomastoid muscle, the cervical plexus comprises a coalition of nerves originating from C1 through C4, which provide input to four cutaneous, seven motor, and three cranial nerves and the sympathetic trunk. Sporadic instances of injury to these superficial nerves have been reported. Nevertheless, this specific anatomical cause of neurogenic pain remains incompletely described and underrecognized. METHODS: Twelve patients presented with pain and were diagnosed with various combinations of injury to the lesser occipital, great auricular, transverse cervical, and supraclavicular nerves. Inciting events included prior face lift, migraine, and thoracic outlet procedures; and traumatic events including seatbelt trauma, a fall, and a clavicular fracture. History and examination suggested injury to the cervical plexus, and nerve blocks confirmed the diagnoses. Neurectomy with intramuscular transposition was performed for three nerve branches in one patient, two branches in two patients, and one branch in the remaining nine patients. RESULTS: Nine of the twelve patients had complete relief of their cervical plexus-related pain. The three failures were in patients with pain after previous face-lift surgery. Residual perception of neck tightness and choking sensation persisted despite relief of cheek and ear pain. CONCLUSIONS: Knowledge of the cervical plexus anatomy and its branches is crucial for surgeons operating in this area to minimize iatrogenic nerve injury. In addition, neuromas should be considered a likely cause of pain and dysesthesia following surgery or injury. Proper diagnosis and surgical intervention can have a significantly positive effect on these debilitating problems. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V. PMID- 29595738 TI - Patient-Reported Outcome Measures Used in Gender Confirmation Surgery: A Systematic Review. AB - BACKGROUND: The usefulness of patient-reported outcome measures is emphasized along with the development of patient-centered care. When implementing patient reported outcome measures, evidence of the instrument's validity, reliability, and responsiveness in the target population is necessary to secure accurate reporting of the patient's experience. The aim of this study was to identify the literature in which structured patient-reported outcome measures have been used to evaluate the results of gender confirmation surgery, and to systematically evaluate the validity of these instruments. METHODS: A systematic review of the current literature was performed to identify structured patient-reported outcome measures used to evaluate the outcome of gender confirmation surgery. The identified instruments' validity in the transgender population was assessed for adherence to international guidelines for development and validation of health outcomes instruments. RESULTS: A total of 110 instruments were identified: 64 ad hoc; six generic; 24 evaluating psychiatric, social, or psychosocial aspects; nine evaluating function but only valid in other patient groups; five ad hoc with some formal development/validation; and two specific for gender dysphoria. CONCLUSIONS: There is a lack of patient-reported outcome measures that are valid for the transgender population and concurrently sensitive enough to evaluate gender confirmation surgery without the influence of other gender confirming interventions. Basing research on instruments without confirmed validity decreases the validity of the study itself; thus, previous research using patient reported outcome measures to evaluate gender confirmation surgery can be considered to have a low level of evidence. To obtain valid patient-reported outcome measures, specific for evaluating the results of gender confirmation surgery, development of new instruments or adaptation of existing instruments is needed.

PMID- 29595741 TI - Learning from an Unsuccessful Study Idea: Reflection and Application of Innovative Techniques to Prevent Future Failures. AB - A well-organized, thoughtful study design is essential for creating an impactful study. However, pressures promoting high output from researchers can lead to rushed study proposals that overlook critical weaknesses in the study design that can affect the validity of the conclusions. Researchers can benefit from thorough review of past failed proposals when crafting new research ideas. Conceptual frameworks and root cause analysis are two innovative techniques that can be used during study development to identify flaws and prevent study failures. In addition, conceptual frameworks and root cause analysis can be combined to complement each other to provide both a big picture and detailed view of a study proposal. This article describes these two common analytical methods and provides an example of how they can be used to evaluate and improve a study design by critically examining a previous failed research idea. PMID- 29595742 TI - Factors Affecting Women's Success in Academic and Private Practice Plastic Surgery.

PMID- 29595747 TI - Postoperative Infection in Patients Undergoing Posterior Lumbosacral Spinal Surgery: A Pictorial Guide for Diagnosis and Early Treatment. AB - Surgical site infections after posterior spinal surgery may lead to spondylodiscitis, pseudarthrosis, correction loss, adverse neurological sequelae, sepsis, and poor outcomes if not treated immediately. Infection rates vary depending on the type and extent of operative procedures, use of instrumentation, and patients' risk factors. Image evaluation is crucial for early diagnosis and should be complementary to clinical routes, laboratory survey, and treatment timing. Magnetic resonance imaging detects early inflammatory infiltration into the vertebrae and soft tissues, including hyperemic changes of edematous marrow, vertebral endplate, and abscess or phlegmon accumulation around the intervertebral disk, epidural, and paravertebral spaces. Aggressive surgical treatment can eradicate infection sources, obtain a stable wound closure, decrease morbidity, and restore spinal integrity. Organ/space infection is defined as any body parts opened to manipulate other than superficial/deep incision. Advanced magnetic resonance imaging evaluating abnormal fluid accumulation, heterogenous contrast enhancement of the endplate erosion due to cage/screw infection is categorized to inform a presumptive diagnosis for early implant salvage. However, patients' defense response, infection severity, bacteriology, treatment timing, spinal stability, and available medical and surgical options must be fully considered. Revision surgery is indicated for pseudarthrosis, implant loosening with correction loss, recalcitrant spondylodiscitis, and adjacent segment diseases for infection control.

AB - Cervical cancer (CC) is the 13th most frequent cancer among women in Norway, but the third most common among women aged 25-49 years. The national screening program sends information letters to promote screening participation. We aimed to evaluate how women's stated intention to participate in screening and pursue treatment changed with the provision of additional information on harms associated with screening, and to assess women's preferences on the timing and source of such information. We administered a web-based questionnaire to a panel of Norwegian women aged 25-69 years and randomized into three groups on the basis of when in the screening process additional information was introduced: (i) invited for routine screening, (ii) recommended an additional test following detection of cellular abnormalities, and (iii) recommended precancer treatment. A fourth (control) group did not receive any additional information. Results show that among 1060 respondents, additional information did not significantly alter women's stated intentions to screen. However, it created decision uncertainty on when treatment was recommended (8.76-9.09 vs. 9.40; 10-point Likert scale; P=0.004). Over 80% of women favored receiving information on harms and 59% preferred that information come from a qualified public health authority. Nearly 90% of women in all groups overestimated women's lifetime risk of CC. In conclusion, additional information on harms did not alter Norwegian women's stated intention to screen for CC; yet, it resulted in greater decision uncertainty to undergo precancer treatment. Incorporating information on harms into invitation letters is warranted as it would increase women's ability to make informed choices. PMID- 29595753 TI - Dose Efficiency of Quarter-Millimeter Photon-Counting Computed Tomography: First in-Human Results. AB - PURPOSE: The aim of this study was to assess the clinical feasibility, image quality, and radiation dose implications of 0.25-mm imaging mode in a cohort of humans, achieved by dividing the photon-counting detector (PCD) size in half compared with standard-resolution photon-counting computed tomography (CT) (0.5 mm). METHODS: In this technical feasibility study, a whole-body prototype PCD-CT scanner was studied in the 0.25 mm detector mode (measured at isocenter). A high resolution PCD-CT protocol was first tested in phantom and canine studies in terms of image noise and spatial resolution. Then, 8 human subjects (mean age, 58 +/- 8 years; 2 men) underwent axial PCD 0.25-mm scans of the brain, the thorax, and at the level of the upper left kidney. Filtered backprojection reconstruction was performed with a sharp kernel (B70) for standard-resolution and high resolution data at 0.5-mm isotropic image voxel. High-resolution data, in addition, were reconstructed with an ultrasharp kernel (U70) at 0.25-mm isotropic voxels. RESULTS: Image reconstructions from the PCD 0.25-mm detector system led to an improvement in resolution from 9 to 18 line pairs/cm in a line pair phantom. Modulation transfer function improved from 9.5 to 15.8 line pairs/cm at 10% modulation transfer function. When fully exploiting this improvement, image noise increased by 75% compared with dose-matched 0.5-mm slice PCD standard resolution acquisition. However, when comparing with standard-resolution data at same in-plane resolution and slice thickness, the PCD 0.25-mm detector mode showed 19% less image noise in phantom, animal, and human scans. CONCLUSION: High resolution photon-counting CT in humans showed improved image quality in terms of spatial resolution and image noise compared with standard-resolution photon counting. PMID- 29595754 TI - The Importance and Quantification of Plutonium Binding in Human Lungs. AB - Epidemiological studies have shown that the main risk arising from exposure to plutonium aerosols is lung cancer, with other detrimental effects in the bone and liver. A realistic assessment of these risks, in turn, depends on the accuracy of the dosimetric models used to calculate doses in such studies. A state-of-the-art biokinetic model for plutonium, based on the current International Commission on Radiological Protection biokinetic model, has been developed for this purpose in an epidemiological study involving the plutonium exposure of Mayak workers in Ozersk, Russia. One important consequence of this model is that the lung dose is extremely sensitive to the fraction (fb) of plutonium, which becomes bound to lung tissue after it dissolves. It has been shown that if just 1% of the material becomes bound in the bronchial region, this will double the lung dose. Furthermore, fb is very difficult to quantify from experimental measurements. This paper summarizes the work carried out thus far to quantify fb. Bayesian techniques have been used to analyze data from different sources, including both humans and dogs, and the results suggest a small, but nonzero, fraction of < 1%. A Bayesian analysis of 20 Mayak workers exposed to plutonium nitrate suggests an fb between 0 and 0.3%. Based on this work, the International Commission on Radiological Protection is currently considering the adoption of a value of 0.2% for the default bound fraction for all actinides in its forthcoming recommendations on internal dosimetry. In an attempt to corroborate these findings, further experimental work has been carried out by the United States Transuranium and Uranium Registries. This work has involved direct measurements of plutonium in the respiratory tract tissues of workers who have been exposed to soluble plutonium nitrate. Without binding, one would not expect to see any activity remaining in the lungs at long times after exposure since it would have been cleared by the natural process of mucociliary clearance. Further supportive study of workers exposed to plutonium oxide is planned. This paper ascertains the extent to which these results corroborate previous inferences concerning the bound fraction. PMID- 29595755 TI - The Pseudo-Pelger huet Cell as a Retrospective Dosimeter: Analysis of a Radium Dial Painter Cohort. AB - Recently, the pseudo-Pelger Huet anomaly in peripheral blood neutrophils has been described as a new radiation-induced, stable biomarker. In this study, pseudo Pelger Huet anomaly was examined in peripheral blood slides from a cohort of 166 former radium dial painters and ancillary personnel in the radium dial industry, 35 of whom had a marrow dose of zero above background. Members of the radium dial painter cohort ingested Ra and Ra at an early age (average age 20.6 +/- 5.4 y; range 13-40 y) during the years 1914-1955. Exposure duration ranged from 1-1,820 wk with marrow dose 1.5-6,750 mGy. Pseudo-Pelger Huet anomaly expressed as a percentage of total neutrophils in this cohort rises in a sigmoidal fashion over five decades of red marrow dose. Six subjects in this cohort eventually developed malignancies: five osteosarcomas and one mastoid cell neoplasm. The pseudo-Pelger Huet anomaly percentage in these cases of neoplasm increases with marrow dose and is best fit with a sigmoid function, suggestive of a threshold effect. No sarcomas are seen for a marrow dose under 2 Gy. These results indicate that pseudo-Pelger Huet anomaly in peripheral blood is a reasonable surrogate for the estimation of alpha dose to bone marrow in historic radiation cases. Hypotheses are discussed to explain late (months to years), early (hours to days), and intermediate (weeks to months) effects of ionizing radiation, respectively, on the expression of genes encoding inner nuclear membrane proteins and their receptors, on the structure and function of nuclear membrane proteins and lipids, and on cytokinesis through chromatin bridge formation.

PMID- 29595756 TI - Tobacco smoking and gastric cancer: meta-analyses of published data versus pooled analyses of individual participant data (StoP Project). AB - Tobacco smoking is one of the main risk factors for gastric cancer, but the magnitude of the association estimated by conventional systematic reviews and meta-analyses might be inaccurate, due to heterogeneous reporting of data and publication bias. We aimed to quantify the combined impact of publication-related biases, and heterogeneity in data analysis or presentation, in the summary estimates obtained from conventional meta-analyses. We compared results from individual participant data pooled-analyses, including the studies in the Stomach Cancer Pooling (StoP) Project, with conventional meta-analyses carried out using only data available in previously published reports from the same studies. From the 23 studies in the StoP Project, 20 had published reports with information on smoking and gastric cancer, but only six had specific data for gastric cardia cancer and seven had data on the daily number of cigarettes smoked. Compared to the results obtained with the StoP database, conventional meta-analyses overvalued the relation between ever smoking (summary odds ratios ranging from 7% higher for all studies to 22% higher for the risk of gastric cardia cancer) and yielded less precise summary estimates (SE <=2.4 times higher). Additionally, funnel plot asymmetry and corresponding hypotheses tests were suggestive of publication bias. Conventional meta-analyses and individual participant data pooled-analyses reached similar conclusions on the direction of the association between smoking and gastric cancer. However, published data tended to overestimate the magnitude of the effects, possibly due to publication biases and limited the analyses by different levels of exposure or cancer subtypes. PMID- 29595758 TI - Surgical Treatment of Early-Stage Cervical Cancer: A Multi-Institution Experience in 2124 Cases in The Netherlands Over a 30-Year Period. AB - OBJECTIVE: This study aimed to describe the pattern of recurrence and survival related to prognostic variables, including type of surgery as a clinical variable, in patients surgically treated for early cervix cancer. METHODS: Records of 2124 patients who underwent a radical hysterectomy for International Federation of Gynaecology and Obstetrics stage I/IIA cervical cancer between 1982 and 2011 were reviewed. Clinical-pathologic prognostic variables, also including extent of parametrectomy, were identified and used in a multivariable Cox proportional hazard model to explore associations between disease-free survival (DFS) and prognostic variables. RESULTS: The 5-year DFS for the total group was 86%. Large tumor diameter, nonsquamous histology, lymph node metastases, parametrial involvement, lymph vascular space invasion, deep stromal invasion, and less radical surgery were independent poor prognostic variables for survival. Disease-free survival was independently associated with the type of radical hysterectomy with pelvic lymphadenectomy in favor of more radical parametrectomy (hazard ratio, 2.0; 95% confidence interval, 1.6-2.5). This difference was not found in tumors with a diameter of at least 20 mm. CONCLUSIONS: This study confirms that variables such as large tumor diameter, nonsquamous histology, lymph vascular space invasion, deep stromal invasion, positive lymph nodes, and parametrial infiltration are poor prognostic variables in early cervix cancer treated by surgery. The extent of parametrectomy had no influence on survival in tumors of 20 mm or less. For larger tumors, a more radical hysterectomy might be associated with better DFS. Taking into account the possible bias in this study as a result of its retrospective design, ideally a prospective cohort study with clear definition of radicality is necessary to answer this important clinical question. PMID- 29595759 TI - Multimodal Management of Locally Advanced Neuroendocrine Cervical Carcinoma: A Single Institution Experience. AB - OBJECTIVE: The aim of this study was to report our institutional experience of a multimodal approach for treatment of locally advanced high-grade neuroendocrine cervical cancer. METHODS AND MATERIALS: Patients with primary locally advanced neuroendocrine cervical cancer diagnosed between 2001 and 2014 were included. The scheduled treatment sequence was as follows: pelvic +/- para-aortic radiotherapy (according to tumor stage), associated with chemotherapy based on platine derivate and etoposide regimen, followed with a brachytherapy boost, then completion surgery if there was no progression +/- consolidation etoposide chemotherapy (for a total of 5-6 cycles). Disease-free survival (DFS) and overall survival (OS) were reported and prognostic factors were searched. RESULTS: A total of 24 patients fulfilled inclusion criteria. Median age was 48 (range 22-77 years). Fourteen patients (58%) had pelvic lymph node metastases. After chemoradiation/brachytherapy, a radical hysterectomy could be performed in 18 of 24 patients (75%). Histologically complete resection was achieved in 14 (78%) of 18 patients. Complete pathological response was reported in 7 (39%) of 18. With median follow-up of 29.7 months, 10 (42%) of 24 patients experienced tumor relapse, all associated with distant failure, including one local failure. The DFS and OS rates estimated at 3 years were 55% and 63%, respectively. Lymph node metastases and tumor stage were prognostic for DFS (P = 0.016 and P = 0.022, respectively). Complete resection was associated with a lower incidence of relapses, as compared with microscopically incomplete resection (P = 0.04). A total of 12 (86%) of 14 patients with histologically complete resection were in complete remission at last follow-up. Apart from manageable acute hematological toxicities, most treatment complications were mild to moderate. CONCLUSIONS: This series based on a multimodal management compares favorably with previously published data. Most patients could be eligible to surgery, and complete remission was achieved in 85% of those amenable to complete resection. PMID- 29595760 TI - Intestinal Surgery in Gynecologic Oncology: Are We Training for the Future? AB - OBJECTIVE: The objective of this study was to assess the scope of intestinal surgery training across gynecologic oncology fellowships in the United States and identify factors associated with perceived preparedness to perform intestinal surgery independently. MATERIALS/METHODS: An institutional review board-approved survey was distributed to Society of Gynecologic Oncology fellows and candidate members within the first 3 years of practice. Questions addressed demographics, operative experience, preparedness and plans for performing intestinal surgery, and attitudes toward gynecologic oncologists (GOs) performing intestinal surgery. Responses were analyzed using descriptive statistics as well as univariate and multivariate analyses. RESULTS: Of 374 Society of Gynecologic Oncology members invited, 108 (29%) responded, including 38 fellows (35%) and 53 recent graduates (49%). Fifteen (14%) reported more than 3 years of practice and were excluded. Most participants (96%) received intestinal surgery training from GOs, and 64% reported that all faculty routinely performed intestinal surgery. Most participants (81%) believed GOs should perform intestinal procedures, whereas only 58% felt prepared and 59% planned to perform intestinal procedures independently. Fellows who performed more than 10 intestinal diversion procedures, participated directed in intestine-related intraoperative consultations, or reported that all faculty performed intestinal surgery were more likely to feel prepared to perform intestinal surgery independently. Sex, training region, intended practice environment, and fellowship curriculum were not associated with preparedness to perform intestinal surgery. CONCLUSIONS: Almost half of gynecologic oncology fellows and recent graduates in the United States do not feel prepared to perform intestinal procedures independently after fellowship. Increased volume and direct involvement of fellows in intestinal surgery may improve preparedness for performing intestinal surgery after fellowship. PMID- 29595761 TI - Cellular Proliferation and Migration of Human Pterygium Cells: Mitomycin Versus Small-Molecule Inhibitors. AB - PURPOSE: Nutlin is a drug that has been reported to activate p53 in various cell lines. We aim to study the effects of Nutlin in pterygium and compare the effects of Nutlin and mitomycin C (MMC) in pterygium cell lines. METHODS: Pterygium samples (n = 3) were collected during surgical excision. Normal conjunctival tissues (n = 3) were collected from another quadrant of the same eye. Cell lines were established, and cells from passages 2 to 5 were used. Pterygium and conjunctival cells were treated with different doses of Nutlin and MMC. Cell proliferation and cell migration were measured. RESULTS: Cell proliferation was reduced by 39-fold after treatment with 50 MUM Nutlin. Cell migration was inhibited with increasing dosages of Nutlin (95% and 28% after treating with 2 and 50 MUM Nutlin, respectively). Compared with MMC, Nutlin induced more pterygium cell death and less conjunctival cell death at low doses. At 50% lethal dose for pterygium cells, 95% of conjunctival cells survived after Nutlin treatment, whereas only 63% of conjunctival cells survived after MMC treatment. p21 expression was not detectable in MMC-treated pterygium cells but was detectable after Nutlin treatment. CONCLUSIONS: In our study, MMC induced cell death in pterygium and conjunctival cell lines, whereas Nutlin had a targeted impact on pterygium cells. Our results implied that MMC inhibited both pterygium cell proliferation and migration through an apoptosis-independent pathway. PMID- 29595762 TI - Transplantation Blues: Inadvertent Staining of Amyloid Deposits With Trypan Blue. AB - PURPOSE: To describe inadvertent persistent staining of stromal amyloid deposits by trypan blue (TB) after penetrating keratoplasty (PK) and Descemet membrane endothelial keratoplasty (DMEK) performed in patients with corneal amyloidosis. METHODS: Case series of patients with corneal amyloidosis in whom intraoperative TB was used. RESULTS: One patient, hospitalized for acute rejection 6 weeks after DMEK, presented with an intense blue staining of small, spindle-shaped structures in the anterior half of the cornea. DMEK had been performed for endothelial failure of a previous PK procedure done 13 years earlier for advanced lattice corneal dystrophy (LCD). After 6 months, the stromal blue tattoo persisted with impaired visual acuity, and PK was performed. Blue-stained structures were amyloid deposits characteristic of LCD recurrence. In parallel, among 85 consecutive triple procedures (PK + cataract + intraocular lens [IOL]) performed over 7 years, in which TB was used, only patients with LCD (n = 18 eyes in 17 patients) or presumed secondary amyloidosis due to chronic inflammation (n = 1), presented an isolated intense blue ring of the graft-host interface. This persisted up to 7 years with no clinical consequence. CONCLUSIONS: TB can stain corneal amyloid deposits. After PK, staining is limited to the recipient peripheral cornea and has no apparent clinical consequence. However, during DMEK performed after a failed PK, TB stains fibrils accumulated during slow LCD recurrence and scattered on the whole graft. The long-term staining duration indicates strong interactions between TB and amyloid. PMID- 29595763 TI - Epithelial Keratitis After Cataract Surgery. AB - PURPOSE: To evaluate the incidence, related perioperative factors, clinical characteristics, and possible etiologies of epithelial keratitis after cataract surgery. METHODS: A retrospective chart review of 666 eyes in 666 patients who underwent cataract surgery was performed to evaluate the incidence of epithelial keratitis and related factors in the postoperative period. RESULTS: Postoperative epithelial keratitis developed in 15 eyes. Eleven of the 15 eyes were diagnosed with herpes simplex keratitis (HSK); 10 of the 11 eyes were diagnosed by polymerase chain reaction, and the remaining 1 eye by clinical diagnosis. All patients diagnosed with HSK had no previous clinical history of the infection before undergoing cataract surgery. Initially, the diagnosis of all 15 eyes was toxic keratitis, but the final diagnosis of 11 of the initial 15 was found to be epithelial herpes keratitis. The incision location was shown to be related to the occurrence of HSK in our study (P < 0.05). CONCLUSIONS: HSK epithelial keratitis after cataract surgery is a relatively uncommon complication and can be misdiagnosed in its early disease course because of its relative rarity. This study explores the possibility that the temporal corneal penetrating incisional approach used in routine cataract surgery interrupts the corneal nerves and subsequently can trigger reactivation of HSK. PMID- 29595765 TI - Contesting the evidence for non-adaptive plasticity. PMID- 29595764 TI - Use of Donor Corneas From Pseudophakic Eyes for Descemet Membrane Endothelial Keratoplasty. AB - PURPOSE: The prevalence of pseudophakia increases with age and affects more than 30% of people older than 80 years. Because grafts from older donors seem to be more suitable for Descemet membrane endothelial keratoplasty (DMEK) surgery rather than grafts from younger donors, eye bank technicians and corneal surgeons have to deal with corneas from pseudophakic donors for DMEK graft preparation. However, graft preparation from corneas of pseudophakic donors can be more complicated. METHODS: We retrospectively analyzed our donor registry for the prevalence of pseudophakia. We compared grafts from phakic and pseudophakic donors concerning graft survival, rebubbling rates, and endothelial cell loss after DMEK surgery. RESULTS: More than 20% of our donors were pseudophakic, of which 35% were primarily suitable for transplantation. Regarding the comparison of grafts from phakic and pseudophakic donors used for DMEK, we observed comparable survival rates (90% after 3 years) and similar endothelial cell loss (30% with an endothelial cell density above 1000 cell/mm after 3 years) but significantly lower rebubbling rates for grafts from pseudophakic donors (18% vs. 28%). CONCLUSIONS: Our data strongly suggest that pseudophakic persons should not be excluded from corneal donation because success rates after DMEK with grafts from pseudophakic eyes are comparable to those with grafts from phakic eyes. However, in the eye bank, grafts from pseudophakic donors have a higher primary discard rate because of low endothelial cell counts. PMID- 29595766 TI - Ghalambor et al. reply.

PMID- 29595767 TI - Planning chemical syntheses with deep neural networks and symbolic AI. AB - To plan the syntheses of small organic molecules, chemists use retrosynthesis, a problem-solving technique in which target molecules are recursively transformed into increasingly simpler precursors. Computer-aided retrosynthesis would be a valuable tool but at present it is slow and provides results of unsatisfactory quality. Here we use Monte Carlo tree search and symbolic artificial intelligence (AI) to discover retrosynthetic routes. We combined Monte Carlo tree search with an expansion policy network that guides the search, and a filter network to pre select the most promising retrosynthetic steps. These deep neural networks were trained on essentially all reactions ever published in organic chemistry. Our system solves for almost twice as many molecules, thirty times faster than the traditional computer-aided search method, which is based on extracted rules and hand-designed heuristics. In a double-blind AB test, chemists on average considered our computer-generated routes to be equivalent to reported literature routes. PMID- 29595768 TI - Is plasticity caused by single genes? PMID- 29595771 TI - Wing origami. PMID- 29595770 TI - A galaxy lacking dark matter. AB - Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that the mass of the dark matter halo and the total stellar mass are coupled through a function that varies smoothly with mass. Their average ratio Mhalo/Mstars has a minimum of about 30 for galaxies with stellar masses near that of the Milky Way (approximately 5 * 1010 solar masses) and increases both towards lower masses and towards higher masses. The scatter in this relation is not well known; it is generally thought to be less than a factor of two for massive galaxies but much larger for dwarf galaxies. Here we report the radial velocities of ten luminous globular-cluster-like objects in the ultra-diffuse galaxy NGC1052 DF2, which has a stellar mass of approximately 2 * 108 solar masses. We infer that its velocity dispersion is less than 10.5 kilometres per second with 90 per cent confidence, and we determine from this that its total mass within a radius of 7.6 kiloparsecs is less than 3.4 * 108 solar masses. This implies that the ratio Mhalo/Mstars is of order unity (and consistent with zero), a factor of at least 400 lower than expected. NGC1052-DF2 demonstrates that dark matter is not always coupled with baryonic matter on galactic scales. PMID- 29595772 TI - US science agencies set to win big in budget deal.

PMID- 29595809 TI - AUDIOME: a tiered exome sequencing-based comprehensive gene panel for the diagnosis of heterogeneous nonsyndromic sensorineural hearing loss. AB - PurposeHereditary hearing loss is highly heterogeneous. To keep up with rapidly emerging disease-causing genes, we developed the AUDIOME test for nonsyndromic hearing loss (NSHL) using an exome sequencing (ES) platform and targeted analysis for the curated genes.MethodsA tiered strategy was implemented for this test. Tier 1 includes combined Sanger and targeted deletion analyses of the two most common NSHL genes and two mitochondrial genes. Nondiagnostic tier 1 cases are subjected to ES and array followed by targeted analysis of the remaining AUDIOME genes.ResultsES resulted in good coverage of the selected genes with 98.24% of targeted bases at >15 *. A fill-in strategy was developed for the poorly covered regions, which generally fell within GC-rich or highly homologous regions. Prospective testing of 33 patients with NSHL revealed a diagnosis in 11 (33%) and a possible diagnosis in 8 cases (24.2%). Among those, 10 individuals had variants in tier 1 genes. The ES data in the remaining nondiagnostic cases are readily available for further analysis.ConclusionThe tiered and ES-based test provides an efficient and cost-effective diagnostic strategy for NSHL, with the potential to reflex to full exome to identify causal changes outside of the AUDIOME test.Genetics in Medicine advance online publication, 29 March 2018; doi:10.1038/gim.2018.48. PMID- 29595811 TI - Familial communication and cascade testing among relatives of BRCA population screening participants. AB - PURPOSE: Population BRCA1/BRCA2 screening identifies carriers irrespective of family history, yet this information is actionable for relatives. We examined familial communication rates and cascade testing in the screening setting and assessed sociodemographic and psychosocial predictors. METHODS: Participants in a BRCA1/BRCA2 screening study of healthy Ashkenazi Jews self-administered a family communication questionnaire. Intent to communicate was determined before genetic status was known, along with result communication (carriers and noncarriers) 6 months and 2 years after enrollment. Carriers underwent in-depth interviews and provided cascade testing information. RESULTS: In total, 88% (524/595) of questionnaire responders and 97% (30/32) of carriers informed at least one relative. In multivariate analysis, family history (P = 0.005) and greater Satisfaction With Health Decision scores (P < 0.001) predicted communication of results. Among carriers' adult first- and second-degree relatives, 71 (48%) had cascade testing, more commonly performed in first- (58%) than in second-degree relatives (26%, P = 0.0002), and in females (56%) vs. males (36%, P = 0.02). At least 11% remained uninformed. CONCLUSION: Familial communication rates and characteristics in a screening setting parallel those reported by Cancer Genetics clinics. Universal screening circumvents dependence on familial disclosure. However, our finding that satisfaction-a potentially modifiable factor-predicts communication, raises the hypothesis that improving the testing experience could facilitate familial communication. PMID- 29595810 TI - Genotype and phenotype correlation in von Hippel-Lindau disease based on alteration of the HIF-alpha binding site in VHL protein. AB - PURPOSE: Von Hippel-Lindau (VHL) disease is a rare hereditary cancer syndrome that reduces life expectancy. We aimed to construct a more valuable genotype phenotype correlation based on alterations in VHL protein (pVHL). METHODS: VHL patients (n = 339) were recruited and grouped based on mutation types: HIF-alpha binding site missense (HM) mutations, non-HIF-alpha binding site missense (nHM) mutations, and truncating (TR) mutations. Age-related risks of VHL-associated tumors and patient survival were compared. RESULTS: Missense mutations conferred an increased risk of pheochromocytoma (HR = 1.854, p = 0.047) compared with truncating mutations. The risk of pheochromocytoma was lower in the HM group than in the nHM group (HR = 0.298, p = 0.003) but was similar between HM and TR groups (HR = 0.901, p = 0.810). Patients in the nHM group had a higher risk of pheochromocytoma (HR = 3.447, p < 0.001) and lower risks of central nervous system hemangioblastoma (CHB) (HR = 0.700, p = 0.045), renal cell carcinoma (HR = 0.610, p = 0.024), and pancreatic tumor (HR = 0.382, p < 0.001) than those in the combined HM and TR (HMTR) group. Moreover, nHM mutations were independently associated with better overall survival (HR = 0.345, p = 0.005) and CHB-specific survival (HR = 0.129, p = 0.005) than HMTR mutations. CONCLUSION: The modified genotype-phenotype correlation links VHL gene mutation, substrate binding site, and phenotypic diversity (penetrance and survival), and provides more accurate information for genetic counseling and pathogenesis studies. PMID- 29595812 TI - Rapid prenatal diagnosis using targeted exome sequencing: a cohort study to assess feasibility and potential impact on prenatal counseling and pregnancy management. AB - PURPOSE: Unexpected fetal abnormalities occur in 2-5% of pregnancies. While traditional cytogenetic and microarray approaches achieve diagnosis in around 40% of cases, lack of diagnosis in others impedes parental counseling, informed decision making, and pregnancy management. Postnatally exome sequencing yields high diagnostic rates, but relies on careful phenotyping to interpret genotype results. Here we used a multidisciplinary approach to explore the utility of rapid fetal exome sequencing for prenatal diagnosis using skeletal dysplasias as an exemplar. METHODS: Parents in pregnancies undergoing invasive testing because of sonographic fetal abnormalities, where multidisciplinary review considered skeletal dysplasia a likely etiology, were consented for exome trio sequencing (both parents and fetus). Variant interpretation focused on a virtual panel of 240 genes known to cause skeletal dysplasias. RESULTS: Definitive molecular diagnosis was made in 13/16 (81%) cases. In some cases, fetal ultrasound findings alone were of sufficient severity for parents to opt for termination. In others, molecular diagnosis informed accurate prediction of outcome, improved parental counseling, and enabled parents to terminate or continue the pregnancy with certainty. CONCLUSION: Trio sequencing with expert multidisciplinary review for case selection and data interpretation yields timely, high diagnostic rates in fetuses presenting with unexpected skeletal abnormalities. This improves parental counseling and pregnancy management. PMID- 29595813 TI - FMR1 allele size distribution in 35,000 males and females: a comparison of developmental delay and general population cohorts. AB - PurposeDevelopmental delay phenotypes have been associated with FMR1 premutation (PM: 55-200 CGG repeats) and "gray zone" (GZ: 45-54 CGG repeats) alleles. However, these associations have not been confirmed by larger studies to be useful in pediatric diagnostic or screening settings.MethodsThis study determined the prevalence of PM and GZ alleles in two independent cohorts of 19,076 pediatric referrals to developmental delay diagnostic testing through Victorian Clinical Genetics Service (cohort 1: N = 10,235; cohort 2: N = 8841), compared with two independent general population cohorts (newborn screening N = 1997; carrier screening by the Victorian Clinical Genetics Service prepair program N = 14,249).ResultsPM and GZ prevalence rates were not significantly increased (p > 0.05) in either developmental delay cohort (male PM: 0.12-0.22%; female PM: 0.26 0.33%; male GZ: 0.68-0.69%; female GZ: 1.59-2.13-%) compared with general population cohorts (male PM: 0.20%; female PM: 0.27-0.82%; male GZ: 0.79%; female GZ: 1.43-2.51%). Furthermore, CGG size distributions were comparable across datasets, with each having a modal value of 29 or 30 and ~1/3 females and ~1/5 males having at least one allele with <=26 CGG repeats.ConclusionThese data do not support the causative link between PM and GZ expansions and developmental delay phenotypes in pediatric settings.GENETICS in MEDICINE advance online publication, 29 March 2018; doi:10.1038/gim.2018.52.

AB - PurposeWhole-exome sequencing (WES) has revolutionized Mendelian diagnostics, however, there is no consensus on the timing of data review in undiagnosed individuals and only preliminary data on the cost-effectiveness of this technology. We aimed to assess the utility of WES data reanalysis for diagnosis in Mendelian disorders and to analyze the cost-effectiveness of this technology compared with a traditional diagnostic pathway.MethodsWES was applied to a cohort of 54 patients from 37 families with a variety of Mendelian disorders to identify the genetic etiology. Reanalysis was performed after 12 months with an improved WES diagnostic pipeline. A comparison was made between costs of a modeled WES pathway and a traditional diagnostic pathway in a cohort with intellectual disability (ID).ResultsReanalysis of WES data at 12 months improved diagnostic success from 30 to 41% due to interim publication of disease genes, expanded phenotype data from referrer, and an improved bioinformatics pipeline.

AB - Purpose: Pediatric-onset multiple sclerosis (POMS) accounts for ~5% of all multiple sclerosis cases, and has a prevalence of ~10,000 children in the USA. POMS is associated with a higher relapse rate, and results in irreversible disability on average 10 years earlier than adult-onset multiple sclerosis. Other manifestations of POMS include mental and physical fatigue, cognitive impairment, and depression. We believe that the health behaviors of physical activity, diet, and sleep may have potential benefits in POMS, and present a scoping review of the existing literature. Methods: We identified papers by searching three electronic databases (PubMed, GoogleScholar, and CINAHL). Search terms included: pediatric multiple sclerosis OR pediatric onset multiple sclerosis OR POMS AND health behavior OR physical activity OR sleep OR diet OR nutrition OR obesity. Papers were included in this review if they were published in English, referenced nutrition, diet, obesity, sleep, exercise, or physical activity, and included pediatric-onset multiple sclerosis as a primary population. Results: Twenty papers were identified via the literature search that addressed health-promoting behaviors in POMS, and 11, 8, and 3 papers focused on diet, activity, and sleep, respectively. Health-promoting behaviors were associated with markers of disease burden in POMS. Physical activity participation was associated with reduced relapse rate, disease burden, and sleep/rest fatigue symptoms. Nutritional factors, particularly vitamin D intake, may be associated with relapse rate. Obesity has been associated with increased risk of developing POMS. POMS is associated with better sleep hygiene, and this may benefit fatigue and quality of life. Discussion: Participation in health behaviors, particularly physical activity, diet, and sleep, may have benefits for POMS. Nevertheless, there are currently no interventions targeting promotion of these behaviors and examining the benefits of managing the primary and secondary manifestations of POMS.

AB - Background: Specific foods and nutrients, including alcohol, may contribute to gut barrier dysfunction. However, to our knowledge, the influence of whole diets is currently unknown. Objective: We aimed to cross-sectionally investigate associations of dietary patterns with plasma soluble CD14 (sCD14), which is released by macrophages on stimulation with endotoxin and has been used as a marker of gut hyperpermeability. Methods: We used food-frequency questionnaire data collected from 689 women in the Nurses' Health Study and 509 men in the Health Professionals Follow-Up Study. Our principal component analysis identified 2 dietary patterns: "Western" (higher intakes of red meat, processed meat, desserts, and refined grains) and "prudent" (higher intakes of fruits, vegetables, fish, and whole grains). In multivariable-adjusted logistic regression analyses, we estimated ORs and 95% CIs for high (equal to or greater than the median compared with less than the median) sCD14 concentrations in quintiles of each dietary pattern. Using logistic regression, we also investigated the joint association of the Western dietary pattern and alcohol intake or C-reactive protein (CRP) with sCD14 concentrations. Results: Western dietary pattern scores were positively associated with sCD14 concentrations (OR: 1.86; 95% CI: 1.24, 2.79; P-trend = 0.0005; comparing extreme quintiles). Analyses of joint associations suggested that the strongest associations with higher sCD14 concentrations were for persons with both high Western pattern scores and high alcohol intake compared with participants with low scores for both (OR: 2.96; 95% CI: 1.61, 5.45) or for participants with both high Western pattern scores and high CRP values compared with those with low scores for both (OR: 4.11; 95% CI: 2.57, 6.58). The prudent pattern was not associated with sCD14 concentrations. Conclusions: Higher consumption of the Western dietary pattern is associated with a marker of macrophage activation and gut hyperpermeability, especially when coupled with high alcohol intake and heightened systemic inflammation. Our findings need confirmation in studies with additional markers of gut barrier dysfunction.

AB - The aim of this article is to investigate the claim that tourism development can be the engine for poverty reduction in Kenya using a dynamic, microsimulation computable general equilibrium model. The article improves on the common practice in the literature by using the more comprehensive Foster-Greer-Thorbecke (FGT) index to measure poverty instead of headcount ratios only. Simulations results from previous studies confirm that expansion of the tourism industry will benefit different sectors unevenly and will only marginally improve poverty headcount. This is mainly due to the contraction of the agricultural sector caused the appreciation of the real exchange rates. This article demonstrates that the effect on poverty gap and poverty severity is, nevertheless, significant for both rural and urban areas with higher impact in the urban areas. Tourism expansion enables poorer households to move closer to the poverty line. It is concluded that the tourism industry is pro-poor.

The N/C abundance anomaly seen is ~10% of cataclysmic variables and the presence of absorption lines due to heavy elements in suprasolar abundance are discussed. A synthetic spectral analysis of the FUSE spectrum of the old nova RR Pic reveals reveals an accretion disk with i = 60 degrees , Mwd = 1.0M? and a high accretion rate of 10-8M?/yr. New evidence from the FUSE and IUE spectra of the symbiotic system CQ Dra suggest it is a triple system consisting of a red giant and a cataclysmic variable companion.

AB - In this study, we report a porous-carbon-based Mo2C nanocomposite (NCs) as the microwave absorber via typical carbothermal reduction using metal-organic frameworks (MOFs) and polyoxometalates (POMs) as the precursors, which have been rarely applied in electromagnetic (EM) wave absorption areas. The elaborately designed NCs not only bring about good impedance matching, but also possess strong dissipation ability due to the large surface areas and porous features. Thanks to the material characteristics as well as structural advantages, the as prepared Mo2C/C NCs with 20 wt% sample loading exhibit remarkable microwave absorbing performance. The minimum RL value reaches -49.19 dB at matching thickness of 2.6 mm, and the best effective bandwidth (RL < -10 dB) of 4.56 GHz at 1.70 mm was also achieved. Moreover, the NCs overcome the intrinsic drawback of traditional carbon materials, that is, centralized effective absorption always occurred at high frequency (>10 GHz) and the minimum RL value of the NCs shifted to 9.04 GHz. Clearly, in this study, we not only developed the Mo2C NC as the new light absorber, but also paved the way to synthesize other available transition metal carbides using MOFs and POMs. PMID- 29595843 TI - Reduction-responsive amphiphilic polymeric prodrugs of camptothecin polyphosphoester for cancer chemotherapy. AB - As one of the promising prodrug strategies, amphiphilic polymeric prodrugs can be constructed by conjugating some small molecular hydrophobic anticancer drugs onto a hydrophilic biodegradable and biocompatible polymer, which further self assembles into nanoparticles with controllable drug loading. Here, a biocompatible and biodegradable polyphosphoester and a broad-spectrum anticancer drug camptothecin (CPT) were selected as model compounds. We first designed and synthesized a novel cyclic phosphoester monomer (CPTSP) containing a disulfide bond linker and CPT as a side group. Then a reduction-responsive amphiphilic polymeric prodrug (PCPTSP-co-PEEP) was prepared through the ring-opening copolymerization of CPTSP and a common cyclic phosphoester monomer containing ethyl (EEP) as the side group, which was initiated by benzyl alcohol with 1,8 diazabicycloundec-7-ene (DBU) and thiourea (TU) as catalysts. The resulting PCPTSP-co-PEEPs could self-assemble into micelles in water due to their hydrophilic polyphosphoester main chain and some hydrophobic CPT side groups. The average size and the drug loading content of these micelles can be controlled by adjusting the feed molar ratio of EEP and CPTSP. The average hydrodynamic diameter increased from 190 nm to 250 nm when the molar ratio of EEP/CPTSP was adjusted from 9/1 to 49/1. These micelles possessed appropriate stability under physiological conditions and degraded in the reduction medium according to their change in size monitored by DLS measurement. Their reduction-responsive properties were also confirmed by the in vitro drug release behavior. Moreover, these micelles could enter into HT29 tumor cells via endocytosis and released CPT efficiently to inhibit their proliferation. The in vivo tumor inhibition rate of these polymeric prodrugs was 73.4%, which was about two fold that for free CPT (36.5%). This approach of polymeric prodrugs based on polyphosphoesters can be extended to other anticancer drugs to construct smart drug delivery systems for cancer treatment. PMID- 29595845 TI - Real-time detection of the nanoparticle induced phytotoxicity in rice root tip through the visible red emissions of Eu3+ ions. AB - Phytotoxicity is one of the most important factors involved in the reduction of crop production. With the introduction of NaBiF4 nanoparticles, the effect of the particle size (>50 nm) on rice development was systematically studied. Through the exogenous treatment of multiple concentrations of nanoparticles, the primary root length, lateral root number, and lateral root length were significantly inhibited under higher content of nanoparticles, but more crown root formation was induced, which might be due to phytotoxicity. With the help of the red emission of the Eu3+-activated NaBiF4 nanoparticles, we could infer that the nanoparticles were accumulated in the root tip cells in the division and elongation zone but not in the mature region. Additionally, the investigation on the influence of the studied nanoparticles on the gene level and the expression of phytotoxicity related genes was performed to further identify the effect of the nanoparticles on the rice root development. These results potentially explain the effect of larger nanoparticles on phytotoxicity in the plant roots.

AB - alpha-Arylated alanine derivatives were made enantioselectively by migratory rearrangement of a urea derivative using (R,R)-pseudoephedrine as a chiral auxiliary. Incorporation of a single residue of the product alpha-methyl phenylglycine into an otherwise achiral oligomer of aminoisobutyric acid oligomer induced a preferred screw sense, detectable by a NMR reporter located at the remote terminus of the oligomer. The magnitude of the screw sense induction was greater when the chiral residue was located at the N-terminus of the foldamer, and in some cases the sense of induction was opposite to that of related alpha methylated amino acids with alpha-substituents other than aryl.

AB - A simple and efficient protocol for the C4-H phosphonation of 8-hydroxyquinoline derivatives was developed under a photoredox/silver(i) cocatalysis system, providing a new approach to phosphonated 8-hydroxyquinoline derivatives. Note that the reaction did not occur at the C5 site, but regioselectively at an unusual C4 site. Moreover, the reaction proceeded smoothly under mild reaction conditions (a catalytic amount of silver salt and room temperature) with good functional group compatibility. PMID- 29595849 TI - Cobalt phosphide/carbon dots composite as an efficient electrocatalyst for oxygen evolution reaction. AB - The oxygen evolution reaction (OER) is a promising energy conversion system, which has been studied a lot in recent years. However, owing to the high overpotential and sluggish kinetics of the OER, an efficient electrocatalyst is necessary to lower the overpotential and accelerate the reaction. In this paper, we report a cobalt phosphide (CoP)/carbon dots (CDs) composite as an electrocatalyst for the OER for the first time. A facile two-step method was used to synthesize the CoP/CDs composite and the concentration of CDs in the composite was further regulated. The experimental results show that when the amount of CDs in the composite is 6 mg (28.79 wt%C), the obtained CoP/CDs composite exhibits optimal electrocatalytic activity (with an overpotential of 400 mV in 1 M KOH at a current density of 10 mA cm-2) and high stability towards the OER. The good electrocatalytic activity of the composite is attributed to the small size of CoP and CDs and rapid electron transfer of CDs.

AB - In this study, we examined the thickness of the electrical double layer (EDL) in ionic liquids using density functional theory (DFT) calculations and molecular dynamics (MD) simulations. We focused on BF4- anion adsorption from the 1-ethyl-3 methylimidazolium tetrafluoroborate (EMImBF4) ionic liquid on the Au(111) surface. At both DFT and MD levels, we evaluated the capacitance-potential dependence for the Helmholtz model of the interface. Using MD simulations, we also explored a more realistic, multilayer EDL model accounting for the ion layering. Concurrent analysis of the DFT and MD results provides a ground for thinking whether the electrical double layer in ionic liquids is one- or multi ionic-layer thick. PMID- 29595848 TI - Multivalent conjugates of basic fibroblast growth factor enhance in vitro proliferation and migration of endothelial cells. AB - Growth factors hold great promise for regenerative therapies. However, their clinical use has been halted by poor efficacy and rapid clearance from tissue, necessitating the delivery of extremely high doses to achieve clinical effectiveness which has raised safety concerns. Thus, strategies to either enhance growth factor activity at low doses or to increase their residence time within target tissues are necessary for clinical success. In this study, we generated multivalent conjugates (MVCs) of basic fibroblast growth factor (bFGF), a key growth factor involved in angiogenesis and wound healing, to hyaluronic acid (HyA) polymer chains. Multivalent bFGF conjugates (mvbFGF) were fabricated with minimal non-specific interaction observed between bFGF and the HyA chain. The hydrodynamic radii of mvbFGF ranged from ~50 to ~75 nm for conjugation ratios of bFGF to HyA chains at low (10 : 1) and high (30 : 1) feed ratios, respectively. The mvbFGF demonstrated enhanced bioactivity compared to unconjugated bFGF in assays of cell proliferation and migration, processes critical to angiogenesis and tissue regeneration. The 30 : 1 mvbFGF outperformed the 10 : 1 conjugate, which could be due to either FGF receptor clustering or interference with receptor mediated internalization and signal deactivation. This study simultaneously investigated the role of both protein to polymer ratio and multivalent conjugate size on their bioactivity, and determined that increasing the protein-to-polymer ratio and conjugate size resulted in greater cell bioactivity. PMID- 29595851 TI - Highly sensitive flexible three-axis tactile sensors based on the interface contact resistance of microstructured graphene. AB - The lack of high-performance tactile sensors, especially for pressure/force, is a huge obstacle for the widespread application of intelligent robots. Current pressure sensors are often operated in the high range of pressure and normal direction, showing a little ability in the low range of pressure and three-axis direction simultaneously. Herein, a highly sensitive flexible tactile sensor with three-axis force sensing capacity is presented by combining microstructured polydimethylsiloxane (PDMS) arrays and a reduced graphene oxide (rGO) film. The deformation of microstructured rGO/PDMS results in a change in the contact area between the rGO film and electrode, leading to a high sensitivity of -1.71 kPa-1 in the low range pressure of 0-225 Pa with a fast response time of 6 ms at a large feature size of 100 MUm. To realize three-axis sensing, a sensing unit was built up, which was composed of the adjacent four parts of patterns and electrodes underneath a bump. A mechanical model of the exerted spatial force was established to calculate each axis force component via the deformation of the rGO/PDMS pattern. The experimental results show that the current difference between the adjacent two parts has a strong relationship with the applied force. As a proof of concept, we have demonstrated a 3 * 3 array sensor for arbitrary force sensing. Our tactile sensor would be used in transmitting information from a gentle spatial force and would exhibit broad applications as e-skin in integrated robots. PMID- 29595852 TI - Composite-dissolving microneedle patches for chemotherapy and photothermal therapy in superficial tumor treatment. AB - A combination of chemotherapy and photothermal therapy (PTT) has emerged as a promising strategy for cancer therapy. To ensure that the chemotherapeutic drug and photothermal agent can be simultaneously delivered to the tumor site to exert their synergistic effects, a safe and efficient delivery system is needed. Herein, we fabricated doxorubicin hydrochloride (DOX)- and indocyanine green (ICG)-loaded microneedle (MN) patches (PVP@DOX/MSN@ICG) using a two-step casting process. Mesoporous silica nanoparticles (MSNs) were used to improve the ICG stability and avoid reducing its PTT efficiency in vivo. The MN patches exhibited a good skin penetration ability, and the tips of the MN patches were dissolved by the interstitial fluid to release DOX and ICG at the tumor sites. Under 808 nm laser irradiation within 2 min, the local temperature in the tumor quickly reached 48 degrees C at a low power of 0.34 W cm-2. A combination of chemotherapy and PTT for PVP@DOX/MSN@ICG MN patches may maximally induce human osteosarcoma MG-63 cells in vitro. Moreover, the in vivo results showed that PVP@DOX/MSN@ICG MN patches had the best antitumor effects because of synergistic chemotherapy and PTT. Therefore, the composite-dissolving MN patch is a promising strategy for enhancing the antitumor effect of chemotherapy alone and shows the potential for the synergistic therapy of superficial tumors. PMID- 29595853 TI - Phenethyl isothiocyanate in combination with dibenzoylmethane inhibits the androgen-independent growth of prostate cancer cells. AB - Phenethyl isothiocyanate (PEITC) is a naturally occurring compound found in some cruciferous vegetables. Dibenzoylmethane (DBM) is a minor constituent of licorice. Both compounds have been shown to exert anticancer activities. In the present study, we determined the effects of PEITC and DBM alone or in combination on androgen-independent growth of human prostate cancer cells cultured in vitro and prostate VCaP xenograft tumors in severe combined immunodeficient (SCID) mice. PEITC and DBM in combination had stronger effects on inhibiting the growth and inducing apoptosis than either compound alone in cultured prostate cancer cells. The combination also strongly inhibited cell migration and the formation of tumorspheres in VCaP cells. Mechanistic studies showed that the combined effects of PEITC and DBM on growth inhibition and apoptosis were associated with suppression of nuclear factor-kappaB (NF-kappaB), and a decrease in the levels of survivin and phospho-Akt (pAkt). In the in vivo study, SCID mice bearing VCaP tumors were surgically castrated and treated with PEITC and/or DBM. Treatment with PEITC and DBM in combination resulted in a strong inhibition of the progression of androgen-dependent VCaP prostate tumors to androgen independence. Our results indicate that administration of DBM and PEITC in combination may be an effective strategy for inhibiting/delaying the progression of prostate cancer to androgen independence. PMID- 29595856 TI - Predicting an unconventional facile route to metallaanthracenes. AB - Metallaaromatics have attracted considerable interest from both experimentalists and theoreticians since the first prediction of metallabenzenes, in which a CH group is replaced by a transition metal fragment. In comparison with monocyclic metallabenzenes and bicyclic metallanaphthalenes, tricyclic metallaanthracenes are quite less developed. Thus, it is urgent to explore synthetic methods for this rare system. Here we report a thorough investigation on the formation of metallaanthracenes from transition metal fluorenyl complexes via density functional theory calculations. We systematically investigate how metal centres, ligands, and substituents affect such a rearrangement. Our results indicate that formation of metallaanthracenes could become thermodynamically and kinetically favourable from transition metal fluorenyl complexes by tuning suitable metal centres, ligands, and substituents, suggesting an unconventional facile way to prepare such rare tricyclic metallaaromatics for experimentalists, which is in sharp contrast to the traditional isomerisation of metallabenzenes to cyclopentadienyl complexes. PMID- 29595858 TI - Calycosin directly improves perivascular adipose tissue dysfunction by upregulating the adiponectin/AMPK/eNOS pathway in obese mice. AB - Perivascular adipose tissue (PVAT) loses its anti-contractile activity in obesity. Calycosin, the major bioactive isoflavonoid, was shown to protect endothelial function. However, effects of calycosin on PVAT function in obesity remain unclear. We aimed to investigate the effects of calycosin on the anti contractile activity of PVAT in obese mice and its potential mechanisms. Obesity in mice was induced with a high-fat diet, with or without calycosin treatment. Thoracic aorta responses to phenylephrine were determined. AMP protein kinase (AMPK) and endothelial nitric oxide synthase (eNOS) levels were analyzed by western blotting. Adiponectin, TNF-alpha levels and superoxide production were measured in the PVAT. Calycosin treatment significantly increased the anti contractile response of PVAT, which was impaired in obese mice. This beneficial effect of calycosin was eliminated by treatments of blocking adiponectin, AMPK or eNOS. Similar results were observed for calycosin treatment ex vivo. Treatment of obese mice with calycosin significantly increased adiponectin levels, activated AMPK and eNOS phosphorylation and reduced superoxide production and TNF-alpha levels in PVAT. Our results indicated that calycosin restored PVAT induced anti contractile activity and affected PVAT function through the adiponectin/AMPK/eNOS pathway in obese mice. PMID- 29595859 TI - Nanocrystal heterostructures of LiCoO2 with conformal passivating shells. AB - Stabilization of electrode-electrolyte interfaces is required to increase the energy stored in battery electrodes. Introducing redox-inactive ions on the electrode surface minimizes deleterious side reactions without affecting the bulk properties. A synthetic challenge exists to grow such layers conformally at each primary particle, to fully passivate interfaces that are buried in the final electrode architecture. The development of methods of sequential colloidal growth of complex oxides and overlayers, enabled by surfactant interactions, would provide novel means to advance toward this goal. Here, nanocrystals composed of LiCoO2, a commercially relevant material for high energy devices, were grown with a shell enriched in Al3+, deposited conformally through a one-pot colloidal synthetic method. The effects of synthetic conditions on the composition of the Al-rich shell and the corresponding electrochemical performance were investigated. The modified nanocrystals showed enhanced electrochemical properties, while maintaining carrier transport. PMID- 29595861 TI - Bis(selenobenzoato)dibutyltin(iv) as a single source precursor for the synthesis of SnSe nanosheets and their photo-electrochemical study for water splitting. AB - A new organo-tin complex has been synthesized and used as a single source precursor for the synthesis of SnSe nanosheets by the hot injection method and thin films by the aerosol assisted chemical vapor deposition (AACVD) method. The films were deposited on glass substrates at three different temperatures. The textural quality and preferential growth were found to be significantly altered by changes in the deposition temperature. Oleylamine capped nanosheets and the as deposited thin films by AACVD were characterized by powder X-ray diffraction (p XRD) and microscopic techniques. The thin films were also studied by Raman spectroscopy. The stoichiometry is marginally affected by temperature, and all films were slightly selenium deficient. The synthesized material was also evaluated for the photoelectrochemical (PEC) splitting of water. The PEC study revealed the bifunctional nature of the material, which can be applied for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), by switching the applied potential. PMID- 29595860 TI - Relationship between copper(ii) complexes with FomA adhesin fragments of F. nucleatum and colorectal cancer. Coordination pattern and ability to promote ROS production. AB - The copper(ii) ion binding of the Ac-KGHGNG-NH2 and Ac-PTVHNE-NH2 fragments of FomA adhesin from Fusobacterium nucleatum was studied using potentiometry, UV Vis, CD, EPR and DFT techniques. The coordination pattern was described in a wide range of pH values. Ligands begin interactions with metal ions using imidazole nitrogen. At pH 6.8 (a value typical of the large intestine environment), the metal ion was coordinated by the 3N donor atoms {Nim, 2 * N-amide} in both cases. However, the copper(ii) ion was bound more effectively by the Ac-PTVHNE-NH2 peptide. The formation of reactive oxygen species (ROS) was studied by UV-Vis and fluorescence spectroscopy, as well as gel electrophoresis in the presence of H2O2 and/or ascorbic acid. The complexes generated ROS in the highest amounts among all compounds. Moreover, they stimulated the CT26 cell line (mouse colon carcinoma) to produce ROS which lead to oxidative stress. It was also determined that such radicals took part in the plasmid degradation mechanism.

AB - INTRODUCTION: Skin lesions can be defined as lesions that result in loss of tissues and their joints, and often this cutaneous skin process is a primary or secondary consequence of the structural changes in the skin itself. Subjects with peripheral arteripathies that develop chronic skin lesions in the lower extremities of the Western world are constantly increasing. We conducted a study on the etiologic incidence of chronic skin lesions in peripheral arterial disease CSLpa subjects in the lower limbs compared to subjects with chronic skin lesions CSL (controls). MATERIALS AND METHODS: 30 subjects with peripheral atheropathies PA (22 F - 8 M mean age 74,5 +/- 4,9) and with chronic skin lesions (CSLpa) in the lower limbs "A" group were admitted to our study according to a randomized and compared to 30 no peripheral atheropathies subjects (19 F-11 M, mean age 81,5 +/- 7,3 - controls) group B with chronic skin lesions (CSL). These two groups "A" and "B" have been studied and compared on the basis of infectious etiology responsible for the infectious skin process. RESULTS: In the subjects of the "A" group we found a 12 positive assay of 40.0% of the examinations, while in the group "B" we achieved a total cultured positivity of 9 cases corresponding to 30.0% of the examinations . For the number of bacterial species identified for "A" group we obtained 3 mono microbial and 6 poly microbial bacteriological tests and for group "B" we observed 7 mono microbial and 2 poly microbial tests. All bacteriological isolates showed "in vitro" sensitivity to satisfactory ciprofloxacin with MICs range of 0.78-1.56mg/L. The data observed after 4 weeks after the amniotic membrane (MA) in the two study groups A and B were respectively the following: and for group A 50% scarring, 46.6% partial resolution and in one case worsening for the B-healing group in 63.3%, the partial resolution in the remaining 36.6. CONCLUSIONS: The data from this study show a different etiology between subjects with CSLpa than subjects with CSL. This phenomenon confirms an alteration of the skin microbioma of subjects with peripheral arteriopathy and chronic skin lesions with modification of the opportunistic role of some species of cutaneous bacterial flora. PMID- 29595865 TI - Germline Editing: Editors Cautionary. AB - This communication is regarding the recent editing of the genome of the human embryo with CRISPR/Cas9 which generated a debate amongst the biological scientists around the world. Editing human germline genes may act as godsend in some serious genetic and other disorders as the genes related to these disorders can be replaced effectively. The scientists are in dilemma whether the human germline gene modification is a boon or bane for the human society. Though editing human germline genes may be an answer to many serious genetic disorders however; it may have unpredictable effects on future generations. The ethical issues regarding the germline editing need further discussion which may have implications on human race and on-going human evolution. Thus, the researchers need to be doubly cautious and some stringent regulations should be framed regarding the various aspects of germ line gene modifications and any potential conflict with nature for future outcome. PMID- 29595867 TI - Aesthetic satisfaction in lip and palate clefts: a comparative study between secondary and tertiary bone grafting. AB - Lip and palate cleft represent one of the most frequently occurring congenital deformity, which includes dental anomalies, such as variation in tooth number and position. In case of hypodontia implant-prosthetic rehabilitation offers significant advantages in terms of function, aesthetics and quality of life and bone graft is usually needed. Secondary bone grafting, generally performed in the mixed dentition phase (years 8-11) seems to be the most successful method to allow for rehabilitation. It's often necessary to perform a tertiary bone grafting in adult age in order to achieve better bone quantity and quality before implant placement. Aim of this retrospective study was to evaluate the aesthetic perception that patients had of themselves comparing dental implants placed in tertiary grafted alveolar cleft sites with a previous secondary grafting to only secondary grafting. Between 2009 and 2012, fourteen alveolar cleft were treated with implant rehabilitation and eleven of them received tertiary bone grafting six months prior to implant placement. All patients were questioned to give a score from 1 to 10 their aesthetic satisfaction of their smile before and after implant rehabilitation and during pre-surgery provisional rehabilitation. At the end of their prosthesis rehabilitation patients who received tertiary bone grafting resulted more satisfied than those who had secondary bone grafting only (9.5 vs 8). PMID- 29595868 TI - Iatrogenic hypoparathyroidism after surgery for retrosternal goitre. A single centre retrospective analysis. AB - AIM: The aim of this study is to assess, retrospectively, the incidence of secondary hypoparathyroidism after total thyroidectomy in patients with retrosternal goitre. MATERIAL AND METHODS: From January 2009 to September 2015, 622 patients who undergone total thyroidectomy for goitre, were retrospectively observed. The patients were divided into two group: Group A, including 58 patients with retrosternal goitre and Group B, including 562 patients with in situ goitre. Those patients with diseases of the parathyroid glands, assumption of drugs modifying calcium metabolism and who received blood transfusions before or after surgery, were excluded from the study. In both groups, a total thyroidectomy was performed under general anaesthesia. The upper and lower parathyroid glands in both groups were observed in situ as well. All surgical specimens underwent histological examination. RESULTS: Transient hypocalcaemia was observed in a higher percentage in group A (15% vs 7%, P <0.05). The mean hospital stay was greater in group A (P <0.05). There were no statistically differences between the two groups in terms of permanent hypocalcaemia and post operative blood ionized calcium (72hours and 1 month). CONCLUSIONS: Many efforts should be made to respect parathyroids during total thyroidectomy in retrosternal goitre; greater attention should be given to inferior parathyroid glands that should be displayed, respecting the vasculature and performing a terminal lower thyroid artery ligation in order to reduce the risk of transient hypocalcaemia and - as a consequence - the average hospital stay.

AB - BACKGROUND: Cystic Fibrosis (CF) is an autosomal recessive genetic disease. Two models for screening CF are normally used: newborn screening and population-based CF carrier screening. In turn, there are three main models of population-based CF carrier screening: prenatal carrier screening, preconception carrier screening, and carrier screening outside clinical settings. AIM: To evaluate, in the light of the personalist view, the use of carrier screenings for CF outside the clinic, i.e. in non-clinical settings, such as school and workplaces. METHODS: Analysis has been carried out according to the "Personalist approach" (also called "Triangular model"), an ethical method for performing ethical analysis within HTA process. It includes factual, anthropological and ethical data in a ''triangular'' normative reflection process. FINDINGS: Implementing carrier screening for cystic fibrosis outside the clinical settings allows acquisition of knowledge for informing reproductive choices, that can be considered as valuable; benefit-risk ratio seems to be not much favorable; autonomous and responsible decisions can be taken only under certain conditions; economic advantage is difficult to determine; therefore, from a personalist view, implementing carrier screenings outside the clinic seems not to be ethically justified. CONCLUSIONS: In accordance with the personalist perspective, public health programs providing carrier screenings outside the clinic should not be implemented. PMID- 29595870 TI - Law on advance health care directives: a medical perspective. AB - The paper's authors aim to elaborate on law 22 dicembre 2017, n. 219 , designed to regulate informed consent practices and advance health care directives", which has sparked a passionate debate centered on the substantial innovation achieved over the past decades in bio-medical science and at the same time, the noteworthy accomplishments made in enforcing human and personal rights. Within the paper, article three is delved into, which covers the creation of the so-called DAT ("Disposizioni anticipate di trattamento", advance health care directives), by which patients, in light of possible future incapacity to choose, can express their convictions and decisions on how to be treated and their consent or dissent to undergo treatments and procedures, including artificial nutrition and hydration. The authors peruse the new law's provisions through a medical perspective, and observe how they are heavily tilted towards patient choice, thus making doctors little more than mere tools of such decisions. PMID- 29595871 TI - Guidelines and best practices: remarks on the Gelli-Bianco law. AB - The paper's authors aim to elaborate on the innovations brought by law n. 24/2017, issued by the Italian Parliament with a close focus on art. 5, which pertains to the drafting of guidelines and the adoption of best practices. The guidelines constitute in fact an element of innovation brought by the above mentioned law, and compliance with them can shield from possible liability those health care professionals who find themselves embroiled in professional accidents while in the fulfillment of their duties. Besides, there are several critical aspects within the law that need to be highlighted as well. As far as best practices are concerned, the lawmakers who drafted the legislation make no mention as to the standards of evidence needed in order to characterize any given professional behavior as "best practice". The reform appears unlikely to be effective in providing doctors with clear behavioral standards, thus reducing the margin for liability claims against them. PMID- 29595872 TI - Headaches Through a Woman's Life. AB - Importance: Headaches affect women across their life span, with menses, pregnancy, and menopause being times that pose unique challenges in diagnosis and treatment. The correct diagnosis and treatment of headache can prevent unnecessary interventions, the worsening of chronic headache disorders, and complications of secondary headaches. Objective: The objective of this article is to educate women's health care providers about the diagnosis, differential diagnosis, and treatment of headache during menses, pregnancy, the puerperium, and menopause to improve the quality of care for women with chronic and acute headache. Evidence Acquisition: Current articles were reviewed addressing headache during menses, pregnancy, the postpartum period, and menopause. Articles with the highest level of evidence were compiled in this article to provide a summary of recommendations. Results: Multiple diagnostic and therapeutic options for chronic and acute headache are available for women regardless of their stage in life or comorbidities. Conclusions and Relevance: The effects of headaches span a woman's life span, with puberty and menopause being times of increased frequency. Pregnancy is an at-risk time for women to develop secondary headache disorders. All women's health care providers should know how to screen for, diagnose, and treat headache at all stages of a woman's life. Effective treatment options are available for acute and chronic headache both during and outside pregnancy. PMID- 29595873 TI - Pain Management for First-Trimester Uterine Aspiration. AB - Importance: First-trimester uterine aspiration can easily be performed in the office setting if adequate pain management for the patient is achieved. It is important for clinicians to understand evidence-based approaches for pain control to ensure a safe and efficient procedure. Objective: This article reviews the literature regarding pharmacologic and nonpharmacologic pain control options for first-trimester abortion performed in the clinical setting. Preoperative, procedural, and postoperative pain control are all reviewed. Evidence Acquisition: Authors searched the online database PubMed for relevant published literature through January 2018. To identify possible publications for review, the key word "abortion" was paired with the following key words: "pain," "pain control," "pain management," "aspiration," "paracervical block," "sedation, "non pharmacologic," and "post-operative." Results: Optimizing pain control for first trimester uterine aspiration may involve interventions before, during, and after the surgery. Evidence shows patients benefit from premedication with nonsteroidal anti-inflammatory drugs, a defined paracervical block technique, and an option to use one of several nonpharmacologic interventions. Conclusions and Relevance: Pain management for first-trimester uterine aspiration should be individualized for optimal patient satisfaction. Evidence supports multiple approaches to support this individualization. Targeted interventions before, during, and after the procedure should be offered to improve procedure experience and satisfaction. PMID- 29595874 TI - Temporal analysis of cardiovascular control and function following incomplete T3 and T10 spinal cord injury in rodents. AB - Spinal cord injury (SCI) is a devastating condition that results in whole-body dysfunction, notably cardiovascular (CV) disruption and disease. Injury-induced destruction of autonomic pathways in conjunction with a progressive decline in physical fitness contribute to the poor CV status of SCI individuals. Despite the wide use of exercise training as a therapeutic option to reduce CV dysfunction, little is known about the acute hemodynamic responses to the exercise itself. We investigated CV responses to an exercise challenge (swimming) following both high and low thoracic contusion to determine if the CV system is able to respond appropriately to the challenge of swimming. Blood pressure (BP) telemetry and echocardiography were used to track the progression of dysfunction in rodents with T3 and T10 SCI (n = 8 each) for 10 weeks postcontusion. At 1 week postinjury, all animals displayed a drastic decline in heart rate (HR) during the exercise challenge, likely a consequence of neurogenic shock. Furthermore, over time, all groups developed a progressive inability to maintain BP within a narrow range during the exercise challenge despite displaying normal hemodynamic parameters at rest. Echocardiography of T10 animals revealed no persistent signs of cardiac dysfunction; T3 animals exhibited a transient decline in systolic function that returned to preinjury levels by 10 weeks postinjury. Novel evidence provided here illustrates that incomplete injuries produce hemodynamic instability that only becomes apparent during an exercise challenge. Further, this dysfunction lasts into the chronic phase of disease progression despite significant recovery of hindlimb locomotion and cardiac function. PMID- 29595875 TI - Impaired autonomic function in adolescents born preterm. AB - Preterm birth temporarily disrupts autonomic nervous system (ANS) development, and the long-term impacts of disrupted fetal development are unclear in children. Abnormal cardiac ANS function is associated with worse health outcomes, and has been identified as a risk factor for cardiovascular disease. We used heart rate variability (HRV) in the time domain (standard deviation of RR intervals, SDRR; and root means squared of successive differences, RMSSD) and frequency domain (high frequency, HF; and low frequency, LF) at rest, as well as heart rate recovery (HRR) following maximal exercise, to assess autonomic function in adolescent children born preterm. Adolescents born preterm (less than 36 weeks gestation at birth) in 2003 and 2004 and healthy age-matched full-term controls participated. Wilcoxon Rank Sum tests were used to compare variables between control and preterm groups. Twenty-one adolescents born preterm and 20 term-born controls enrolled in the study. Preterm-born subjects had lower time-domain HRV, including SDRR (69.1 +/- 33.8 vs. 110.1 +/- 33.0 msec, respectively, P = 0.008) and RMSSD (58.8 +/- 38.2 vs. 101.5 +/- 36.2 msec, respectively, P = 0.012), with higher LF variability in preterm subjects. HRR after maximal exercise was slower in preterm-born subjects at 1 min (30 +/- 12 vs. 39 +/- 9 bpm, respectively, P = 0.013) and 2 min (52 +/- 10 vs. 60 +/- 10 bpm, respectively, P = 0.016). This study is the first report of autonomic dysfunction in adolescents born premature. Given prior association of impaired HRV with adult cardiovascular disease, additional investigations into the mechanisms of autonomic dysfunction in this population are warranted. PMID- 29595876 TI - Exercise mitigates the effects of hyperhomocysteinemia on adverse muscle remodeling. AB - Hyperhomocysteinemia (HHcy) is known for causing inflammation and vascular remodeling, particularly through production of reactive oxygen species (ROS) and matrix metalloproteinase-9 (MMP-9) activation. Although its effect on the skeletal muscle is unclear, HHcy can cause skeletal muscle weakness and functional impairment by induction of inflammatory mediators and macrophage mediated injury. Exercise has been shown to reduce homocysteine levels and therefore, could serve as a promising intervention for HHcy. The purpose of this study was to investigate whether HHcy causes skeletal muscle fibrosis through induction of inflammation and determine whether exercise can mitigate these effects. C57BL/6J (WT) and CBS+/- (HHcy) mice were administered a 6 weeks treadmill exercise protocol. Hindlimb perfusion was measured via laser Doppler. Measurement of skeletal muscle protein expression was done by western blot. Levels of skeletal muscle MMP-9 mRNA were determined by qPCR. Collagen deposition in the skeletal muscle was measured using Masson's trichrome staining. In CBS+/- mice, HHcy manifested with decreased body weight and femoral artery lumen diameter, as well as a trend of lower hindlimb perfusion. These mice displayed increased wall to lumen ratio, mean arterial blood pressure, collagen deposition, and elevated myostatin protein expression. Exercise mitigated the effects above in CBS+/- mice. Skeletal muscle from CBS+/- mice had elevated markers of remodeling and hypoxia: iNOS, EMMPRIN, and MMP-9. We conclude that HHcy causes skeletal muscle fibrosis possibly through induction of EMMPRIN/MMP-9 and exercise is capable of mitigating the pathologies associated with HHcy. PMID- 29595878 TI - AKT2 is the predominant AKT isoform expressed in human skeletal muscle. AB - Skeletal muscle physiology and metabolism are regulated by complex networks of intracellular signaling pathways. Among many of these pathways, the protein kinase AKT plays a prominent role. While three AKT isoforms have been identified (AKT1, AKT2, and AKT3), surprisingly little is known regarding isoform-specific expression of AKT in human skeletal muscle. To address this, we examined the expressions of each AKT isoform in muscle biopsy samples collected from the vastus lateralis of healthy male adults at rest. In muscle, AKT2 was the most highly expressed AKT transcript, exhibiting a 15.4-fold increase over AKT1 and AKT3 transcripts. Next, the abundance of AKT protein isoforms was determined using antibody immunoprecipitation followed by Liquid Chromatography-Parallel Reaction Monitoring/Mass Spectrometry. Immunoprecipitation was performed using either mouse or rabbit pan AKT antibodies that were immunoreactive with all three AKT isoforms. We found that AKT2 was the most abundant AKT isoform in human skeletal muscle (4.2-fold greater than AKT1 using the rabbit antibody and 1.6 fold greater than AKT1 using the mouse antibody). AKT3 was virtually undetectable. Next, cultured primary human myoblasts were virally-transduced with cDNAs encoding either wild-type (WT) or kinase-inactive AKT1 (AKT1-K179M) or AKT2 (AKT2-K181M) and allowed to terminally differentiate. Myotubes expressing WT-AKT1 or WT-AKT2 showed enhanced fusion compared to control myotubes, while myotubes expressing AKT1-K179M showed a 14% reduction in fusion. Myotubes expressing AKT2 K181M displayed 63% decreased fusion compared to control. Together, these data identify AKT2 as the most highly-expressed AKT isoform in human skeletal muscle and as the principal AKT isoform regulating human myoblast differentiation. PMID- 29595877 TI - Effects of HIV-1 gp120 and tat on endothelial cell sensescence and senescence associated microRNAs. AB - The aim of this study was to determine, in vitro, the effects of X4 and R5 HIV-1 gp120 and Tat on: (1) endothelial cell senescence and (2) endothelial cell microRNA (miR) expression. Endothelial cells were treated with media without and with: R5 gp120 (100 ng/mL), X4 gp120 (100 ng/mL), or Tat (500 ng/mL) for 24 h and stained for senescence-associated beta-galactosidase (SA-beta-gal). Cell expression of miR-34a, miR-217, and miR-146a was determined by RT-PCR. X4 and R5 gp120 and Tat significantly increased (~100%) cellular senescence versus control. X4 gp120 significantly increased cell expression of miR-34a (1.60 +/- 0.04 fold) and miR-217 (1.52 +/- 0.18), but not miR-146a (1.25 +/- 0.32). R5 gp120 significantly increased miR-34a (1.23 +/- 0.07) and decreased miR-146a (0.56 +/- 0.07). Tat significantly increased miR-34a (1.49 +/- 0.16) and decreased miR-146a (0.55 +/- 0.23). R5 and Tat had no effect on miR-217 (1.05 +/- 0.13 and 1.06 +/- 0.24; respectively). HIV-1 gp120 (X4 and R5) and Tat promote endothelial cell senescence and dysregulation of senescence-associated miRs.

PMID- 29595879 TI - Capturing the multifactorial nature of ARDS - "Two-hit" approach to model murine acute lung injury. AB - Severe acute respiratory distress syndrome (ARDS) presents typically with an initializing event, followed by the need for mechanical ventilation. Most animal models of ALI are limited by the fact that they focus on a singular cause of acute lung injury (ALI) and therefore fail to mimic the complex, multifactorial pathobiology of ARDS. To better capture this scenario, we provide a comprehensive characterization of models of ALI combining two injuries: intra tracheal (i.t.) instillation of LPS or hypochloric acid (HCl) followed by ventilator-induced lung injury (VILI). We hypothesized, that mice pretreated with LPS or HCl prior to VILI and thus receiving a ("two-hit injury") will sustain a superadditive lung injury when compared to VILI. Mice were allocated to following treatment groups: control with i.t. NaCl, ventilation with low peak inspiratory pressure (PIP), i.t. HCl, i.t. LPS, VILI (high PIP), HCl i.t. followed by VILI and LPS i.t. followed by VILI. Severity of injury was determined by protein content and MPO activity in bronchoalveolar lavage (BAL), the expression of inflammatory cytokines and histopathology. Mice subjected to VILI after HCl or LPS instillation displayed augmented lung injury, compared to singular lung injury. However, mice that received i.t. LPS prior to VILI showed significantly increased inflammatory lung injury compared to animals that underwent i.t. HCl followed by VILI. The two-hit lung injury models described, resulting in additive but differential acute lung injury recaptures the clinical relevant multifactorial etiology of ALI and could be a valuable tool in translational research. PMID- 29595882 TI - High-Prevalence and Low-Intensity Ichthyophonus Infections in Pacific Halibut. AB - Ichthyophonus occurred at high prevalence but low intensity in Pacific Halibut Hippoglossus stenolepis throughout the West Coast of North America, ranging from coastal Oregon to the Bering Sea. Infection prevalence in adults was variable on spatial and temporal scales, with the lowest prevalence typically occurring on the edges of the geographic range and highest prevalence consistently occurring inside Prince William Sound, Alaska (58-77%). Additionally, intra-annual differences occurred at Albatross-Portlock, Alaska (71% versus 32% within 2012), and interannual differences occurred along coastal Oregon (50% in 2012 versus 12% in 2015). The infection prevalence was influenced by host age, increasing from 3% or less among the youngest cohorts (age <= 6) to 39-54% among age-9-17 cohorts, then decreasing to 27% among the oldest (age-18+) cohorts. There was little indication of significant disease impacts to Pacific Halibut, as the intensity of infection was uniformly low and length at age was similar between infected and uninfected cohorts. These results suggest that Ichthyophonus in Pacific Halibut currently represents a stable parasite-host paradigm in the North Pacific. PMID- 29595883 TI - Comparison of Sampling and Detection Methods for Chinook Salmon and Steelhead Naturally Infected with Myxobolus cerebralis. AB - Myxobolus cerebralis (Mc) is a myxozoan parasite causing whirling disease in hatchery- and natural-origin salmonids. To minimize spread of this parasite and the incidence of its associated disease, fish health professionals routinely screen fish for Mc before stocking or moving the fish to Mc-free waters. Sample collection for Mc traditionally entails lethal sampling of cranial tissue followed by pepsin-trypsin digest (PTD) and screening of the sample for mature myxobolid myxospores (PTD method); however, nonlethal sampling methods would be advantageous in some circumstances, such as when dealing with rare or otherwise valuable fish. Accordingly, we compared Mc detections in cranial cartilage by using the PTD method with PCR assays of fin biopsies collected from juvenile Chinook Salmon Oncorhynchus tshawytscha and adult steelhead O. mykiss. Cranial samples were also analyzed using PCR methods for comparative purposes. Results indicated that Mc could be detected by PCR in fin clips, but the results generated by this approach differed significantly from those associated with PTD- and/or PCR-based analysis of cranial cartilage samples. Polymerase chain reaction based analysis-of individual head samples and head digest pools in both species as well as fins in steelhead-yielded more positive detections than PTD analysis alone. The PCR-based analysis of head and fin tissues yielded different Mc detection rates in both species, but the nature of the detection disparity varied depending on the species and/or life stage of the fish. We conclude that for lethal cranial samples, neither PTD nor PCR should be used alone, but using these techniques in concert may provide the most complete and accurate estimation of Mc presence in a group of salmonids. If imperiled or highly valuable fish are in question, nonlethal fin samples may be used to generate some information regarding Mc status, with the understanding that parasite DNA detections do not necessarily signify mature infections or disease. PMID- 29595884 TI - Swimming Endurance in Juvenile Chinook Salmon Infected with Salmincola californiensis. AB - Juvenile Chinook Salmon Oncorhynchus tshawytscha moving downstream through tributaries of the upper Willamette River basin can spend months in reservoirs created by dams. While residing in the reservoirs, they often obtain heavy infections of the freshwater parasitic copepod Salmincola californiensis. The physiologic effect these parasites have on salmonids is poorly understood. We developed a method to infect juvenile Chinook Salmon in a laboratory with the copepodid stage of S. californiensis. Infected and uninfected fish were subjected to a swimming challenge to ascertain swimming endurance. Severity of gill damage was assessed using a dissecting microscope. Juvenile Chinook Salmon naturally infected with S. californiensis in Cougar Reservoir, Oregon, were also challenged and compared with their lab-infected counterparts. Copepod infection greatly impaired the swimming ability of laboratory fish, and the naturally infected fish were entirely incapable of swimming at low velocity. Chinook Salmon collected in the wild were more heavily infected than the laboratory fish and had trouble surviving collection and transport to our laboratory. The intensity of infection and severity of gill damage were positively correlated with diminished swimming ability, suggesting that heavy infection with copepods impairs gas exchange and osmotic regulation, which likely results in diminished fitness and decreased survival of infected fish. PMID- 29595881 TI - The influence of thoracic gas compression and airflow density dependence on the assessment of pulmonary function at high altitude. AB - The purpose of this report was to illustrate how thoracic gas compression (TGC) artifact, and differences in air density, may together conflate the interpretation of changes in the forced expiratory flows (FEFs) at high altitude (>2400 m). Twenty-four adults (10 women; 44 +/- 15 year) with normal baseline pulmonary function (>90% predicted) completed a 12-day sojourn at Mt. Kilimanjaro. Participants were assessed at Moshi (Day 0, 853 m) and at Barafu Camp (Day 9, 4837 m). Typical maximal expiratory flow-volume (MEFV) curves were obtained in accordance with ATS/ERS guidelines, and were either: (1) left unadjusted; (2) adjusted for TGC by constructing a "maximal perimeter" MEFV curve; or (3) adjusted for both TGC and differences in air density between altitudes. Forced vital capacity (FVC) was lower at Barafu compared with Moshi camp (5.19 +/- 1.29 L vs. 5.40 +/- 1.45 L, P < 0.05). Unadjusted data indicated no difference in the mid-expiratory flows (FEF25-75% ) between altitudes (? + 0.03 +/- 0.53 L sec-1 ; ? + 1.2 +/- 11.9%). Conversely, TGC-adjusted data revealed that FEF25-75% was significantly improved by sojourning at high altitude (? + 0.58 +/- 0.78 L sec-1 ; ? + 12.9 +/- 16.5%, P < 0.05). Finally, when data were adjusted for TGC and air density, FEFs were "less than expected" due to the lower air density at Barafu compared with Moshi camp (?-0.54 +/- 0.68 L sec-1 ; ? 10.9 +/- 13.0%, P < 0.05), indicating a mild obstructive defect had developed on ascent to high altitude. These findings clearly demonstrate the influence that TGC artifact, and differences in air density, bear on flow-volume data; consequently, it is imperative that future investigators adjust for, or at least acknowledge, these confounding factors when comparing FEFs between altitudes. PMID- 29595885 TI - Identification of Differentially Regulated Edwardsiella ictaluri Proteins During Catfish Serum Treatment. AB - Edwardsiella ictaluri is a facultative, intracellular, gram-negative bacterium that causes enteric septicemia of catfish (ESC). Edwardsiella ictaluri is known to be resistant to defense mechanisms present in catfish serum, which might aid in its use of a host's bloodstream to become septicemic. However, the precise mechanisms of the survival of E. ictaluri in host serum are not known. Analysis of the response of E. ictaluri to the host serum treatment at a proteomic level might aid in the elucidation of its adaptation mechanisms against defense mechanisms present in catfish serum. Thus, the objective of this study was to identify differentially regulated proteins of E. ictaluri upon exposure to naive catfish serum. Two-dimensional difference gel electrophoresis (2D-DIGE) followed by in-gel trypsin digestion and MALDI-TOF/TOF analysis were used for identification of differentially expressed E. ictaluri proteins. A total of 19 differentially regulated proteins (7 up- and 12 downregulated) were identified. Among those were four putative immunogenic proteins, two chaperones and eight proteins involved in the translational process, two nucleic acid degradation and integration proteins, two intermediary metabolism proteins, and one iron-ion binding protein. Further research focusing on the functions of these differentially expressed proteins may reveal their roles in host adaptation by E. ictaluri. PMID- 29595886 TI - Toxicity of Potassium Chloride Compared to Sodium Chloride for Zebra Mussel Decontamination. AB - The use of chemicals to decontaminate watercraft and/or equipment after exposure to zebra mussels Dreissena polymorpha is one method of decontamination that has been recommended by multiple government agencies in the United States. The ideal chemical to be used for decontamination would be inexpensive and easily obtained, would have no or limited effect on nontarget species, and would be relatively environmentally friendly. Two chemicals that have been tested are potassium chloride (KCl) and sodium chloride (NaCl). The toxicity of each chemical to both adult zebra mussels and veliger larvae was examined. Sodium chloride was less effective at causing mortality than KCl within the exposure periods tested. Adult mussels required a 4* longer exposure period to exhibit complete mortality when exposed to NaCl at 30,000 mg/L (24 h) compared to KCl (6 h). At 10,000 mg/L, NaCl took 8* longer (96 h) than KCl (12 h) to cause 100% mortality of adult mussels. Veligers that were exposed to KCl at 1,250 mg/L required a 12-h exposure to attain complete mortality, while those exposed to NaCl at 10,000 mg/L required an 18-h exposure to exhibit the same result. To determine whether KCl is more advantageous as a decontamination chemical, the cost and chemical availability must be researched. PMID- 29595887 TI - Histological Alterations in Pacific Oysters Crassostrea gigas that Survived a Summer Mortality Event in Baja California, Mexico. AB - A mortality episode (>90%) of triploid and diploid Pacific oysters Crassostrea gigas cultured in Baja California Sur occurred during summer 2012, coinciding with a thermal anomaly, an algal bloom, and low oxygen values. To help explain the cause of the mortalities, histological analyses and molecular tests for specific pathogens (ostreid herpesvirus 1 [OsHV-1] and Perkinsus marinus) were performed on oysters surviving at the end of the episode. Triploid oysters showed a high percentage of males (43%) and hermaphrodites (30%); 93% of these oysters were in the gonadic reabsorption stage, and in some cases, hemocytes completely filled the lumen of the gonadic follicles. Oysters presented large areas with severe hemocyte infiltration that extended toward the digestive gland. Diploid oysters showed similar gonad alterations. None of samples showed histological or molecular evidence of OsHV-1 or P. marinus. Histological alterations can be related to physiological disorders caused by the mechanism driving summer mortality. This is the first case history of a summer mortality episode among Pacific oysters in Mexico. PMID- 29595888 TI - Humoral Immune Responses to Select Marine Bacteria in Loggerhead Sea Turtles Caretta caretta and Kemp's Ridley Sea Turtles Lepidochelys kempii from the Southeastern United States. AB - Serum from Kemp's ridley sea turtles Lepidochelys kempii and loggerhead sea turtles Caretta caretta was collected during summer in 2011, 2012, and 2013. Serum immunoglobulin Y (IgY) recognition of lysate proteins from nine bacterial species and whole bacterium-specific IgY titers to these pathogens were quantified. Serum and purified IgY recognized proteins of all bacteria, with protein recognition for some species being more pronounced than others. Circulating IgY titers against Vibrio vulnificus, V. anguillarum, Erysipelothrix rhusiopathiae, and Brevundimonas vesicularis changed over the years in Kemp's ridley sea turtles, while IgY titers against V. vulnificus, Escherichia coli, V. parahaemolyticus, B. vesicularis, and Mycobacterium marinum were different in loggerhead sea turtles. Serum lysozyme activity was constant for loggerhead sea turtles over the 3 years, while activity in Kemp's ridley sea turtles was lower in 2011 and 2012 than in 2013. Blood packed cell volume, glucose, and serum protein levels were comparable to those of healthy sea turtles in previous studies; therefore, this study provides baseline information on antibody responses in healthy wild sea turtles. PMID- 29595889 TI - Dietary Onion or Ginger Modulates the Stress Response and Susceptibility to Vibrio harveyi JML1 Infection in Brown-marbled Grouper Epinephelus fuscoguttatus Juveniles. AB - Onion Allium cepa and ginger Zingiber officinale have health-promoting properties that qualify them as functional foods. The effect of repeated acute stressors was examined in juvenile Brown-marbled Grouper Epinephelus fuscoguttatus that were fed four diets supplemented with onion at 1.8%, ginger at 1.8%, vitamin C at 0.86%, and beta-glucan at 0.8% of the diet. The non-supplemented diet served as the control. After 12 weeks of feeding, fish were exposed to stressors and were experimentally infected with a fish pathogen, the bacterium Vibrio harveyi JML1. After repeated exposure to hypoxia, cortisol levels rose significantly in the non supplemented fish compared to those fed onion, ginger, beta-glucan, or vitamin C. Within groups, postexposure cortisol levels in the onion-, ginger-, and vitamin C fed fish did not change relative to pre-stress levels, whereas significant increases in poststress values were observed in the control and beta-glucan groups. The net cortisol increase was also significantly greater in the non supplemented group compared to the supplemented groups. The net cortisol increase did not vary among the supplemented groups except that the beta-glucan-fed group exhibited a higher net increase than the onion-fed group. Similarly, repeated acute exposure to osmotic stress significantly increased the plasma cortisol level in the non-supplemented group compared to groups that received supplements; no differences were found in the supplemented groups except the beta-glucan group. Within groups, significant increases in poststress values relative to pre stress levels were found only in the control and beta-glucan groups. Repeated acute exposure to hypoxia significantly increased cumulative mortality in the control group compared to the supplemented groups (except the beta-glucan group), whereas repeated exposure to acute osmotic stress significantly increased cumulative mortality only in the control group 10 d after infection with V. harveyi JML1. Based on our collective results, most of the supplemented groups performed better than the control, but the best supplements were onion and ginger in terms of enhancing stress tolerance and increasing survival of Brown-marbled Grouper upon infection with V. harveyi JML1.

AB - Evidence of disease and mortalities of young of the year (age-0) Smallmouth Bass Micropterus dolomieu has occurred during the late spring and summer in many parts of the Susquehanna River watershed since 2005. To better understand contributing factors, fish collected from multiple areas throughout the watershed as well as out-of-basin reference populations (Allegheny and Delaware River basins; experimental ponds, Kearneysville, West Virginia) were examined grossly and histologically for abnormalities. Tissue contaminant concentrations were determined from whole-body homogenates, and water contaminant concentrations were estimated using time-integrated passive samplers at selected sites. Observed or isolated pathogens included bacteria, predominantly motile Aeromonas spp. and Flavobacterium columnare; largemouth bass virus, and parasites, including trematode metacercariae, cestodes, and the myxozoan Myxobolus inornatus. Although these pathogens were found in age-0 Smallmouth Bass from multiple sites, no one pathogen was consistently associated with mortality. Chemicals detected in tissue included polychlorinated biphenyl (PCB) congeners, organochlorine, and current use pesticides. Pyraclostrobin, PCB congeners 170 and 187, cis-chlordane and trans-nonachlor were detected in all Susquehanna watershed samples but rarely in samples from the reference site. The findings support the idea that there is no single cause for disease of age-0 Smallmouth Bass; rather the cumulative effects of co-infections and potential immunomodulation by environmental stressors during a sensitive developmental life stage may lead to mortality. Identifying the most important risk factors will be necessary for more in-depth analyses of individual stressors and better management of the habitat and fish populations. PMID- 29595892 TI - Pediatric Perioperative Nurses and the Ethics of Organ Donation After Cardiac Death. AB - Pediatric perioperative nurses are experiencing increased opportunities to participate in donations after cardiac death. An increased public awareness regarding transplantation has inspired more people to donate than in previous years. The demand for transplantable organs has led to opportunities that have increased donor candidates including living donors and cardiac death donors. Cardiac death in children is often sudden and unexpected, and is an emotional time not only for the family members but also for the hospital staff members, including perioperative nurses. However, when perioperative nurses adhere to standards and guidelines, they can perform their responsibilities in an ethical and compassionate manner and assist their team in doing so. This article reviews the guiding principles of pediatric organ donation after cardiac death, the phases of the process, and the ethical and moral issues surrounding donation.

AB - Care for patients with chronic wounds can be complex, and the chances of poor outcomes are high if wound care is not optimized through evidence-based protocols. Tracking and managing every variable and comorbidity in patients with wounds is difficult despite the increasing use of wound-specific electronic medical records. Harnessing the power of big data analytics to help nurses and physicians provide optimized care based on the care provided to millions of patients can result in better outcomes. Numerous applications of machine learning toward workflow improvements, inpatient monitoring, outpatient communication, and hospital operations can improve overall efficiency and efficacy of care delivery in and out of the hospital, while reducing adverse events and complications. This article provides an overview of the application of big data analytics and machine learning in health care, highlights important recent advances, and discusses how these technologies may revolutionize advanced wound care. PMID- 29595900 TI - A Perioperative Approach to Increase Limb Salvage When Treating Foot Ulcers in Patients With Diabetes. AB - Foot ulceration in patients with diabetes increases the risk of lower extremity amputation. Major amputations produce substantial adverse consequences, increase length of hospital stay, diminish quality of life, and increase mortality. In this article, we describe approaches that decrease amputations and improve the quality of life for patients with diabetes and foot ulcers. We highlight the role of the perioperative nurse, who is essential to providing optimal patient care in the perioperative period. Perioperative care of patients with diabetes involves providing optimal surveillance for a break in the skin of the foot, screening for neuropathy, following guidelines for foot ulcer infections, preparing for pathophysiology-based debridement, using adjuvant therapies, and offloading the patient's affected foot. Nurses should understand the disease process and pathophysiology and how to use these approaches in the perioperative setting to assist in curtailing the morbidity and mortality associated with foot ulcers in patients with diabetes.

AB - Nurses providing surgical care in nonobstetrical ambulatory surgery centers or specialty hospitals without traditional lactation resources may need to care for patients who are breastfeeding. Nurses in these settings play an important role in supporting and protecting the breastfeeding relationship for nursing mothers separated from their infants during illness or surgical procedures. It is important for care providers to understand how hospitalization and the medications administered before, during, and after a surgical procedure affect mothers who are breastfeeding their infants. This article examines the effects of hospitalization on breastfeeding and focuses on preoperative and postoperative care considerations, including medication use, radiology imaging, interrupting and resuming breastfeeding, breast assessment, and milk storage.

PMID- 29595913 TI - Past injurious exercise attenuates activation of primary calcium-dependent injury pathways in skeletal muscle during subsequent exercise. AB - Past contraction-induced skeletal muscle injury reduces the degree of subsequent injury; this phenomenon is called the "repeated bout effect (RBE)." This study addresses the mechanisms underlying the RBE, focusing on primary calcium dependent injury pathways. Wistar rats were subdivided into single injury (SI) and repeated injury (RI) groups. At age 10 weeks, the right gastrocnemius muscle in each rat in the RI group was subjected to strenuous eccentric contractions (ECs). Subsequently, mild ECs were imposed on the same muscle of each rat at 14 weeks of age in both groups. One day after the exercise, the RI group showed a lower strength deficit than did the SI group, and neither group manifested any increase in membrane permeability. The concentration of protein carbonyls and activation of total calpain increased after ECs given at the age of 14 weeks. Nonetheless, these increases were lower in the RI group than in the SI group. Furthermore, calcium-dependent autolysis of calpain-1 and calpain-3 in the RI group was diminished as compared with that in the SI group. Although peak ankle joint torque and total force generation during ECs at the age of 14 weeks were similar between the two groups, phosphorylation of JNK (Thr183 /Tyr185 ), an indicator of mechanical stress applied to a muscle, was lower in the RI group than in the SI group. These findings suggest that activation of the primary calcium-dependent injury pathways is attenuated by past injurious exercise, and mechanical stress applied to muscle fibers during ECs may decrease in the RBE. PMID- 29595914 TI - Uromodulin deficiency alters tubular injury and interstitial inflammation but not fibrosis in experimental obstructive nephropathy. AB - Human GWAS and Mendelian genetic studies have linked polymorphic variants and mutations in the human uromodulin gene (UMOD) with chronic kidney disease. The primary function of this kidney-specific and secreted protein remains elusive. This study investigated whether UMOD deficiency modified responses to unilateral ureteral obstruction (UUO)-induced kidney injury. Kidneys harvested from groups of wild-type (UMOD+/+) and knockout (UMOD-/-) male mice (n = 7-10 each) were studied on days 7, 14, and 21. Compared to sham kidneys, UMOD protein levels increased 9-13x after UUO and were associated with increased urinary UMOD levels. Kidney KIM-1 protein levels were higher in the UMOD-/- groups at all time-points (4-14x). The UMOD-/- groups also had higher KIM-1 kidney-to-urine relative ratios (5-35x). In vitro studies using KIM-1 expressing 769-P cells showed lower KIM-1 levels in the presence of UMOD protein. Levels of proapoptotic genes and the epithelial cell apoptotic protein marker M30 were significantly lower in the UMOD /- groups. Both M30 and KIM-1 colocalized with intraluminal UMOD protein deposits. Interstitial inflammation was less intense in the UMOD-/- groups. Renal fibrosis severity (kidney collagen mRNA and protein) was similar in both genotypic groups on days 7, 14, and 21. Our findings suggest a role for UMOD dependent inhibition of KIM-1 expression and its apoptotic cell scavenging responses during chronic obstruction-associated tubular injury. PMID- 29595915 TI - Dual treatment with a fixed ratio of glucagon and insulin increases the therapeutic window of insulin in diabetic rats. AB - The current available insulin therapies decrease blood glucose but are associated with the risk of developing hypoglycemia. Glucagon is a counter regulatory hormone and we hypothesize that a fixed ratio of insulin and a long-acting glucagon-analogue can reduce the risk of hypoglycemia. To define an appropriate ratio we tested two fixed glucagon doses (3.5 and 10 nmol/kg) in combination with increasing doses of insulin in diabetic rats. We observed a plateau in blood glucose at 15.2 mmol/L with 10 nmol/kg of the glucagon-analogue. The mechanism behind this plateau, protecting against hypoglycemia, was investigated by measuring the glucose output, cAMP production, and hormone binding in primary rat hepatocytes. While glucose output could contribute to the observed plateau in blood glucose, cAMP response or hormone binding did not explain the observation. Though such plateau indicated decreased risk of hypoglycemia a full normalization of blood glucose was still needed. Based on the data obtained with 3.5 nmol/kg of the glucagon-analogue, a 1:23 (glucagon-analogue:insulin) ratio was chosen and a dose-response was performed in diabetic rats. At low doses (<=20 nmol/kg), insulin and the 1:23 ratio showed similar efficacy of lowering blood glucose. Interestingly, the insulin-dose resulting in hypoglycemia was increased from 40 nmol/kg insulin alone to 160 nmol/kg insulin in the 1:23 ratio. Analysis of the liver glycogen content at the end of the experiment showed that the highest dose in the 1:23 ratio almost emptied the liver from glycogen. Thus, liver glycogen is essential for the protective effect of glucagon in hypoglycemia. PMID- 29595916 TI - The complement system in hypertension and renal damage in the Dahl SS rat. AB - Evidence indicates the immune system is important in development of hypertension and kidney disease. In the Dahl Salt-Sensitive (SS) rat model, lymphocytes play a role in development of hypertension and kidney damage after increased sodium intake. Recent transcriptomic analyses demonstrate upregulation of the innate immune complement system in the kidney of Dahl SS rat fed a high-salt diet, leading us to hypothesize that inhibition of complement activation would attenuate development of hypertension and kidney damage. Male Dahl SS rats on a low salt (0.4% NaCl) diet were instrumented with telemeters for continuous monitoring of arterial blood pressure. Animals received saline vehicle (Control) or sCR1, a soluble form of endogenous Complement Receptor 1 (CR1; CD35) that inhibits complement activation. At Day 0, rats were switched to high salt (4.0% NaCl) diet and assigned to sCR1 (15 mg/kg per day) or Control groups with daily ip injections either days 1-7 or days 14-18. Urine was collected overnight for determination of albumin excretion. Treatment with sCR1, either immediately after high-salt diet was initiated, or at days 14-18, did not alter development of hypertension or albuminuria. The sCR1 dose effectively inhibited total hemolytic complement activity as well as C3a generation. High salt caused an increase in message for complement regulator Cd59, with minimal change in Crry that controls the C3 convertase. Thus, innate immune complement activation in the circulation is not critical for development of hypertension and kidney damage due to increased sodium intake, and therapeutic manipulation of the complement system is not indicated in salt-sensitive hypertension. PMID- 29595917 TI - Inhibition of overexpression of Gialpha proteins and nitroxidative stress contribute to sodium nitroprusside-induced attenuation of high blood pressure in SHR. AB - We earlier showed that vascular smooth muscle cells (VSMC) from spontaneously hypertensive rats (SHR) exhibit enhanced expression of Gialpha proteins which was attributed to the decreased levels of nitric oxide (NO), because elevation of the intracellular levels of NO by NO donors; sodium nitroprusside (SNP) and S-Nitroso N-acetyl-DL-penicillamine (SNAP), attenuated the enhanced expression of Gialpha proteins. Since the enhanced expression of Gialpha proteins is implicated in the pathogenesis of hypertension, the present study was undertaken to investigate if treatment of SHR with SNP could also attenuate the development of high blood pressure (BP) and explore the underlying molecular mechanisms. Intraperitoneal injection of SNP at a concentration of 0.5 mg/kg body weight twice a week for 2 weeks into SHR attenuated the high blood pressure by about 80 mmHg without affecting the BP in WKY rats. SNP treatment also attenuated the enhanced levels of superoxide anion (O2- ), hydrogen peroxide (H2 O2 ), peroxynitrite (ONOO- ), and NADPH oxidase activity in VSMC from SHR to control levels. In addition, the overexpression of different subunits of NADPH oxidase; Nox-1, Nox-2, Nox-4, P22phox , and P47phox , and Gialpha proteins in VSMC from SHR were also attenuated by SNP treatment. On the other hand, SNP treatment augmented the decreased levels of intracellular NO, eNOS, and cGMP in VSMC from SHR. These results suggest that SNP treatment attenuates the development of high BP in SHR through the elevation of intracellular levels of cGMP and inhibition of the enhanced levels of Gialpha proteins and nitroxidative stress. PMID- 29595919 TI - Data Quality at the Indiana State Cancer Registry: An Evaluation of Timeliness by Cancer Type and Year. AB - BACKGROUND: Central cancer registries collect tumor-related data to monitor incidence rates and support population-based research. One concern with using registry data for research is timeliness of reporting. Timeliness has beenrecognized as an important data characteristic by both the Centers for Disease Control and Prevention and the NationalAcademy of Medicine. Yet, few studies in the United States have systematically measured timeliness. The purpose of thisstudy is to evaluate timeliness in cancer-case reporting to a state population-based cancer registry. METHOD: Using theIndiana State Department of Health Cancer Registry, 66,395 breast, colorectal, and lung cancer diagnoses recorded duringthe years 2001-2009 were examined for timeliness. Timeliness was measured from the date the cancer was diagnosed towhen the data were available at the state registry. Differences over time and among the 3 cancer types were examined.RESULT: Timeliness of reporting improved since 2003. Mean reporting time ranged from 426 days in 2003 to 253 days in2009. We found significant difference in reporting time between the 3 cancer types. CONCLUSION: Timeliness of reporting hasimproved over time. Advances in health information technologies may have contributed to this improvement. However,achieving even more timely reporting for research purposes and care intervention may require moving away from traditionalreporting methods. PMID- 29595918 TI - Dynamic cerebral autoregulation is preserved during isometric handgrip and head down tilt in healthy volunteers. AB - In healthy humans, cerebral blood flow (CBF) is autoregulated against changes in arterial blood pressure. Spontaneous fluctuations in mean arterial pressure (MAP) and CBF can be used to assess cerebral autoregulation. We hypothesized that dynamic cerebral autoregulation is affected by changes in autonomic activity, MAP, and cardiac output (CO) induced by handgrip (HG), head-down tilt (HDT), and their combination. In thirteen healthy volunteers, we recorded blood velocity by ultrasound in the internal carotid artery (ICA), HR, MAP and CO-estimates from continuous finger blood pressure, and end-tidal CO2 . Instantaneous ICA beat volume (ICABV, mL) and ICA blood flow (ICABF, mL/min) were calculated. Wavelet synchronization index gamma (0-1) was calculated for the pairs: MAP-ICABF, CO ICABF and HR-ICABV in the low (0.05-0.15 Hz; LF) and high (0.15-0.4 Hz; HF) frequency bands. ICABF did not change between experimental states. MAP and CO were increased during HG (+16% and +15%, respectively, P < 0.001) and during HDT + HG (+12% and +23%, respectively, P < 0.001). In the LF interval, median gamma for the MAP-ICABF pair (baseline: 0.23 [0.12-0.28]) and the CO-ICABF pair (baseline: 0.22 [0.15-0.28]) did not change with HG, HDT, or their combination. High gamma was observed for the HR-ICABV pair at the respiratory frequency, the oscillations in these variables being in inverse phase. The unaltered ICABF and the low synchronization between MAP and ICABF in the LF interval suggest intact dynamic cerebral autoregulation during HG, HDT, and their combination. PMID- 29595920 TI - Linkage of Indiana State Cancer Registry and Indiana Network for Patient Care Data. AB - BACKGROUND: Large automated electronic health records (EHRs), if brought together in a federated data model,have the potential to serve as valuable population based tools in studying the patterns and effectiveness of treatment. TheIndiana Network for Patient Care (INPC) is a unique federated EHR data repository that contains data collected from alarge population across various health care settings throughout the state of Indiana. The INPC clinical data environmentallows quick access and extraction of information from medical charts. The purpose of this project was to evaluate 2 differentmethods of record linkage between the Indiana State Cancer Registry (ISCR) and INPC, determine the match rate forlinkage between the ISCR and INPC data for patients diagnosed with cancer, and to assess the completeness of the ISCRbased on additional validated cancer cases identified in the INPC EHRs. METHODS: Deterministic and probabilistic algorithmswere applied to link ISCR cases to the INPC. The linkage results were validated by manual review and the accuracyassessed with positive predictive value (PPV). Medical charts of melanoma and lung cancer cases identified in INPC butnot linked to ISCR were manually reviewed to identify true incidence cancers missed by the ISCR, from which the completenessof the ISCR was estimated for each cancer. RESULTS: Both deterministic and probabilistic approaches to linkingISCR and INPC had extremely high PPV (>99%) for identifying true matches for the overall cohort and each subcohort. Thecombined match rate for melanoma and lung cancer cases identified in the ISCR that matched to any patient occurrence inINPC (not by disease) was 85.5% for the complete cohort, 94.4% for melanoma, and 84.4% for lung cancer. The estimatedcompleteness of capture by the ISCR was 84% for melanoma and 98% for lung cancer. Conclusion: Cancer registries canbe successfully linked to patients' EHR data from institutions participating in a regional health information organization(RHIO) with a high match rate. A pragmatic approach to data linkage may apply both deterministic and probabilisticapproaches together for the diverse purposes of cancer control research. The RHIO has the potential to add value to thestate cancer registry through the identification of additional true incident cases, but more advanced approaches, such asnatural language processing, are needed. PMID- 29595921 TI - Are Benign and Borderline Brain Tumors Underreported? AB - BACKGROUND: Primary benign and borderline (BB) brain tumors have been reportable since 2004 by population-basedcancer registries in the United States. Because these tumors often are diagnosed clinically at nonhospital settings,underreporting is a big concern. Despite this, the magnitude and geographic variations in underreporting are unknown.The objectives of this study are to assess variations in BB brain tumor incidence rate by registry and trend in comparisonto malignant brain tumors, as well as to identify the factors associated with the completeness of BB brain tumor reporting.METHODS: North American Association of Central Cancer Registries (NAACCR) Cancer in North America (CINA) Deluxe1995-2012 Analytic File, which included data from 47 US population-based cancer registries, was used. Age-adjusted incidencerate and average annual percent change (APC) were calculated. Correlation coefficients were used to assess the relationshipsbetween incidence rates and clinical factors. RESULTS: The overall age-adjusted incidence rate was 14.2 per 100,000for BB brain tumors and 6.6 per 100,000 for malignant brain tumors. The age-adjusted incidence rates of BB brain tumorsvaried by registry from 9.8 per 100,000 to 19.9 per 100,000, whereas the variations in malignant brain tumors were muchsmaller from 4.1 per 100,000 to 7.7 per 100,000. BB brain tumor cases were more likely than malignant brain tumors to bediagnosed through radiography without microscopic confirmation or surgery. Overall, the BB brain tumor incidence ratesignificantly increased by 2.3% per year from 2004 to 2012. In contrast, incidence rates of malignant brain tumors significantlydecreased by 0.9% per year in the same period. Higher BB brain tumor incidence rates were significantly associatedwith higher proportions of cases without microscopic confirmation or surgery. These associations were not observed formalignant brain tumors. CONCLUSIONS: Incidence rates of BB brain tumors varied substantially across 47 US registries andwere higher than those of malignant brain tumors in the United States. The variations in incidence rate of BB brain tumorsmay be largely attributable to difference in identifying clinically diagnosed cases. The increasing incidence rate of BB braintumors may reflect improved case ascertainment rather than a biological trend.Key words: PMID- 29595922 TI - Osimertinib in EGFR Mutation-Positive Advanced NSCLC.

AB - BACKGROUND: Age-standardized incidence rates (ASIRs) for US non-Hispanic whites (NHWs) have been increasingsince 1999 for squamous cell carcinomas (SCC) at oropharyngeal (OP) anatomic sites strongly associated with humanpapillomavirus (HPV), as also reported from certain European countries. ASIRs declined slightly, however, from 2000-2006to 2007-2012 in Stockholm County, Sweden (an urban area) for SCC of the tonsil (TSCC) but not base of tongue (BTSCC).For the United States, this study examined the growth of the epidemic of these cancers in 1992 2013. METHODS: Using join-pointregression, trends were examined in ASIRs for BTSCC and TSCC for NHWs in US metropolitan vs nonmetropolitancounties included in a unique Surveillance, Epidemiology, and End Results (SEER) program database covering 1992-2013(11 registries). Representativeness of recent trends was assessed using a larger SEER database (17 registries) covering only2000-2013. RESULTS: ASIRs for NHWs were lower for nonmetropolitan vs metropolitan counties in 1992-1996 but rapidlyincreased and converged over time (especially using SEER 17). There was no decline in rates for TSCC in metropolitancounties, but for BTSCC, the increase was smaller in recent vs earlier years. Reporting delay of cases diagnosed in recentyears was low in both groups of counties. CONCLUSIONS: Findings indicate the need for ongoing surveillance includingadditional US registries, and determining if rates in nonmetropolitan counties will surpass those in metropolitan counties.The rapid rise in rates in SEER nonmetropolitan counties also suggests the need for similar surveillance in countries withlarger rural populations. PMID- 29595940 TI - Co-Care: A Registry for Individuals at Increased Risk for Colorectal Cancer. AB - INTRODUCTION: Colorectal cancer (CRC) is one of the leading causes of cancer death for both men and women in theUnited States. Several factors can increase one's risk of CRC, including a personal or family history of CRC, a diagnosis orfamily history of a hereditary colon cancer syndrome, or a diagnosis of chronic inflammatory bowel disease. The purposeof this project was to create a colorectal cancer registry (Co-Care) for individuals with a personal or family history of CRC,and those with disorders of the colon or rectum that are associated with an increased risk for developing CRC. Methods:To be eligible for the registry, patients either had a personal or family history of CRC, a diagnosis or family history ofLynch syndrome, familial adenomatous polyposis, or a diagnosis of Crohn's colitis or ulcerative colitis with dysplasia.Participants were recruited after seeing their gastroenterologist or genetic counselor, or after undergoing a full or partialcolectomy at Mount Sinai Hospital in New York City. Eligible patients who agreed to participate were interviewed by amember of the research staff and asked a wide range of questions pertaining to CRC risk. RESULTS: A total of 224 patientswere enrolled in the registry. Participants are mostly white, born in the United States, and married, with a bachelor's orgraduate degree, reporting an annual household income of $100,000 or more. The largest portion have a family history ofCRC (27.2%), and almost half of participants are of Jewish descent (46.2%) and have undergone full or partial colectomy(48.2%). More than half of participants have neither received genetic counseling (54.5%) nor undergone genetic testing(59.7%). Only 3.6% report that they currently smoke cigarettes, and 41.1% consume alcohol at least once per week. Lastly,18.3%, 10.3%, and 27.7% of participants report that they currently take aspirin, folic acid/folate pills or tablets, or calciumpills/tablets, respectively. CONCLUSIONS: This registry can improve our understanding of CRC and related diseases, and beused to design future interventions related to disease risk, prognosis, and prevention of CRC.

AB - Data on racial and ethnic subgroups from the National Cancer Institute's Surveillance, Epidemiology, End Results(SEER) program and Census Bureau population estimates are used to estimate cancer incidence rates. A SEER NationalLongitudinal Mortality Study (NLMS) linkage of cancer cases diagnosed during 1973-2001 revealed mismatches in raceclassification from these sources affecting race-specific cancer incidence and mortality rates, particularly for minoritiessuch as American Indians and Alaskan Natives (AIANs). Cancer registries obtain demographic data from various sources,including patient intake and provider records, administrative databases, and imputation algorithms. The primary CensusBureau source for racial/ethnic population denominators is self reported survey data. We examined 7,970 SEER-NLMScases diagnosed during 2003-2011 to update the comparison of patient race/ethnicity in cancer registry and populationdata sets. SEER and self-reported data did not agree for 5% of cases. The sensitivity of SEER data was better for whites(99%) and non-Hispanics (98%) than for multiracial individuals (23%) and all AIANs (40%). Intermediate sensitivities wereseen for blacks as well as AIANs in Indian Health Service contract health service delivery areas (91%), Asians and PacificIslanders (90%), and Hispanics (84%). As the United States becomes more diverse, a need exists to align race and ethnicitydata from central cancer registries with population data, particularly for minority and multiracial groups. High-qualityregistry data on race and ethnicity, collected in a similar way as population estimates, will enhance cancer surveillance.

PMID- 29595945 TI - Medical Record-Documented TNM Categories and Stage Group: Feasibility of Use for Cancer Surveillance. AB - BACKGROUND AND OBJECTIVES: In 2016, with the discontinuation of the Collaborative Staging system, the cancer surveillancecommunity planned to rely on physician assigned TNM stage documented in the medical record. The objectivesof this study were to describe how often physician-assigned staging components were documented in the medical recordsaccessible to the registrar and to assess the agreement of these physician-assigned components with registrar-assignedvalues. METHODS: Medical record documents for 282 routine cases from 5 cancer sites were selected from the Surveillance,Epidemiology, and End Results registries. First, the documents were evaluated to determine how often they contained theTNM staging components. Next, the available components were compared with values assigned by a panel of experiencedcancer registrars. The agreement for each type of source document was estimated among 100 cases. RESULTS: Overall, thephysician-assigned TNM components and stage groups were not often found in the medical record. Pathologic T and Nwere found most frequently (65% and 64%, respectively). Agreement between physician-assigned and registrar-assignedTNM components varied (cT = 57%, cN = 72%, pT = 83%, pN = 89%). For stage group, agreement was better when thestage group was documented more than once (clinical, 71%; pathologic, 67%). Path reports included valid pT and pN in79% and 89% of cases, respectively. Oncology consultation notes provided valid cT for 83% of cases. Validity was lower forother document sources. CONCLUSIONS: The physician-assigned TNM components will rarely be documented in the medicalrecord and available to the registrar. Collection of accurate stage information for cancer surveillance requires cancer registrarsto review the full medical record and assign the TNM components required for stage. PMID- 29595946 TI - Surveillance of Tonsillar Cancer Incidence Rates in Minority Groups vs Non Hispanic Whites in Large US Metropolitan Areas. AB - BACKGROUND: For oropharyngeal (OP) cancers at anatomical sites regarded as related to human papillomavirus(HPV), surveillance using population-based cancer registries has shown that age-standardized incidence rates are higherin US non Hispanic whites (NHWs) vs minority groups. Surveillance in large racially ethnically diverse urban areas alsoshould be considered. METHODS: Using the US Cancer Statistics database, age-standardized incidence rates per year wereobtained for 2003-2013 for carcinomas of the tonsil, the OP site most strongly associated with HPV. Data were available forNHWs, non-Hispanic blacks (NHBs), and Hispanic whites (HWs) in 20 large metropolitan statistical areas (MSAs), and forAsian-Pacific Islanders in 8 of these MSAs. Trends in annual rates were examined using join-point regression. RESULTS: Theoverall rate (2003-2013) was higher for NHWs vs each minority group in almost all MSAs. Little or no NHW NHB differencewas found in 3 MSAs, using abbreviated titles: San Francisco, with a relatively high rate for NHBs; San Diego, withhigh rates for both groups; and Detroit, with a low rate for NHWs and a high rate for NHBs. For individual MSAs withsufficient data for trends in at least 1 minority group, rising rates for NHWs diverged from NBHs and HWs in New York,and from NHBs in Chicago but not from NHBs in Detroit. For HWs, rates increased statistically significantly in the MiamiMSA, vs a smaller increase in the Los Angeles MSA and no increase in the New York MSA. CONCLUSIONS: Surveillance ofOP carcinoma incidence by MSA appears justified, but should use databases that attempt to collect information on racial ethnic subgroups (eg, birthplace and/or ancestry for HWs). PMID- 29595947 TI - Unique Fluorescent Imaging Probe for Bacterial Surface Localization and Resistant Enzyme Imaging. AB - Emergence of antibiotic bacterial resistance has caused serious clinical issues worldwide due to increasingly difficult treatment. Development of a specific approach for selective visualization of resistant bacteria will be highly significant for clinical investigations to promote timely diagnosis and treatment of bacterial infections. In this article, we present an effective method that not only is able to selectively recognize drug resistant AmpC beta-lactamases enzyme but, more importantly, is able to interact with bacterial cell wall components, resulting in a desired localization effect on the bacterial surface. A unique and specific enzyme-responsive cephalosporin probe (DFD-1) has been developed for the selective recognition of resistance bacteria AmpC beta-lactamase, by employing fluorescence resonance energy transfer with an "off-on" bioimaging. To achieve the desired localization, a lipid-azide conjugate (LA-12) was utilized to facilitate its penetration into the bacterial surface, followed by copper-free click chemistry. This enables the probe DFD-1 to be anchored onto the cell surface. In the presence of AmpC enzymes, the cephalosporin beta-lactam ring on DFD-1 will be hydrolyzed, leading to the quencher release, thus generating fluorescence for real-time resistant bacterial screening. More importantly, the bulky dibenzocyclooctyne group in DFD-1 allowed selective recognition toward the AmpC bacterial enzyme instead of its counterpart ( e.g., TEM-1 beta-lactamase). Both live cell imaging and cell cytometry assays showed the great selectivity of DFD-1 to drug resistant bacterial pathogens containing the AmpC enzyme with significant fluorescence enhancement (~67-fold). This probe presented promising capability to selectively localize and screen for AmpC resistance bacteria, providing great promise for clinical microbiological applications. PMID- 29595948 TI - Nanoporous Hydrogels for the Observation of Anthrax Exotoxin Translocation Dynamics. AB - The ability to observe lethal anthrax exotoxins translocating through size constricting nanopores in vitro, combined with detailed sequence and structural data, has aided in elucidated mechanisms of exotoxin cell entry and toxicity. However, due to limited observations of anthrax exotoxins translocating through protective antigen nanopores in vitro and the instability of protective antigen functionalized suspended lipid bilayers, questions remain regarding the native mechanisms of cell entry. Nanoporous hydrogel membranes offer a robust tool for studying protein translocation with ensemble measurements that complement conventional single-molecule translocation measurements. Here, we utilize nanoporous hydrogel membranes to assess the translocation of full-length anthrax lethal and edema factors through nanopores similar in diameter to protective antigen translocons. We find that, relative to globular serum and other proteins that do not translocate natively through nanopores, anthrax exotoxins demonstrate significantly reduced barriers to pore entry. Computed free-energy barriers to the unfolding of proteins and the dissociation of macromolecular complexes are generally found to coincide with translocation. Finally, a nanopore-blocking strategy is developed that utilizes nonspecific synthetic peptide constructs and effectively prevents LF translocation within the nanoporous hydrogel. PMID- 29595949 TI - Orotidine 5'-Monophosphate Decarboxylase: Probing the Limits of the Possible for Enzyme Catalysis. AB - The mystery associated with catalysis by what were once regarded as protein black boxes, diminished with the X-ray crystallographic determination of the three dimensional structures of enzyme-substrate complexes. The report that several high-resolution X-ray crystal structures of orotidine 5'-monophosphate decarboxylase (OMPDC) failed to provide a consensus mechanism for enzyme catalyzed decarboxylation of OMP to form uridine 5'-monophosphate, therefore, provoked a flurry of controversy. This controversy was fueled by the enormous 1023-fold rate acceleration for this enzyme, which had " jolted many biochemists' assumptions about the catalytic potential of enzymes." Our studies on the mechanism of action of OMPDC provide strong evidence that catalysis by this enzyme is not fundamentally different from less proficient catalysts, while highlighting important architectural elements that enable a peak level of performance. Many enzymes undergo substrate-induced protein conformational changes that trap their substrates in solvent occluded protein cages, but the conformational change induced by ligand binding to OMPDC is incredibly complex, as required to enable the development of 22 kcal/mol of stabilizing binding interactions with the phosphodianion and ribosyl substrate fragments of OMP. The binding energy from these fragments is utilized to activate OMPDC for catalysis of decarboxylation at the orotate fragment of OMP, through the creation of a tight, catalytically active, protein cage from the floppy, open, unliganded form of OMPDC. Such utilization of binding energy for ligand-driven conformational changes provides a general mechanism to obtain specificity in transition state binding. The rate enhancement that results from the binding of carbon acid substrates to enzymes is partly due to a reduction in the carbon acid p Ka that is associated with ligand binding. The binding of UMP to OMPDC results in an unusually large >12 unit decrease in the p Ka = 29 for abstraction of the C-6 substrate hydrogen, due to stabilization of an enzyme-bound vinyl carbanion, which is also an intermediate of OMPDC-catalyzed decarboxylation. The protein ligand interactions operate to stabilize the vinyl carbanion at the enzyme active site compared to aqueous solution, rather than to stabilize the transition state for the concerted electrophilic displacement of CO2 by H+ that avoids formation of this reaction intermediate. There is evidence that OMPDC induces strain into the bound substrate. The interaction between the amide side chain of Gln-215 from the phosphodianion gripper loop and the hydroxymethylene side chain of Ser-154 from the pyrimidine umbrella of ScOMPDC position the amide side chain to interact with the phosphodianion of OMP. There are no direct stabilizing interactions between dianion gripper protein side chains Gln-215, Tyr-217, and Arg-235 and the pyrimidine ring at the decarboxylation transition state. Rather these side chains function solely to hold OMPDC in the catalytically active closed conformation. The hydrophobic side chains that line the active site of OMPDC in the region of the departing CO2 product may function to stabilize the decarboxylation transition state by providing hydrophobic solvation of this product. PMID- 29595950 TI - Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films. AB - Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects of growth temperature on the structure, chemical composition, interface coherency and electrical characteristics of rutile VO2 epitaxial thin films grown on TiO2 substrates are investigated. It is hereby deduced that the transition temperature is lower than the bulk value of 340 K. However, it is found to approach this value as a function of increased growth temperature even though it is accompanied by a contraction along the V4+-V4+ bond direction, the crystallographic c-axis lattice parameter. Additionally, it is demonstrated that films grown at low substrate temperatures exhibit a relaxed state and a strongly reduced transition temperature. It is suggested that, besides thermal and epitaxial strain, growth induced defects may strongly affect the electronic phase transition. The results of this work reveal the difficulty in extracting the intrinsic material response to strain, when the exact contribution of all strain sources cannot be effectively determined. The findings also bear implications on the limitations in obtaining the recently predicted novel semi-Dirac point phase in VO2/TiO2 multilayer structures. PMID- 29595951 TI - Amplification of CD20 Cross-Linking in Rituximab-Resistant B-Lymphoma Cells Enhances Apoptosis Induction by Drug-Free Macromolecular Therapeutics. AB - Although the CD20-targeted monoclonal antibody rituximab (RTX) has revolutionized the therapeutic landscape for B-cell malignancy, relapsed and refractory disease due to RTX resistance continue to constitute major challenges, illustrating the need for better therapies. Here, we apply drug-free macromolecular therapeutics (DFMT) that amplifies CD20 cross-linking to enhance apoptosis in RTX-resistant cells. Bispecific engager (anti-CD20 Fab' conjugated with oligonucleotide1) pretargets CD20 and the deletion of Fc-region minimizes its premature endocytosis in resistant cells that rapidly internalize and consume CD20/RTX complexes. Second-step delivery of multivalent polymeric effector (linear copolymer conjugated with multiple copies of complementary oligonucleotide 2) simultaneously hybridizes multiple CD20-bound engagers and strengthens CD20 ligation. Moreover, the restoration of CD20 expression by the pretreatment of cells with a polymer-gemcitabine conjugate, a CD20 expression enhancer, unleashes the full potential of DFMT in the CD20-deficient resistant cells. Hence, amplification of CD20 cross-linking is achieved by (1) the enhancement of surface CD20 accessibility, (2) the increase in CD20 expression, and (3) multimeric CD20 binding, which ultimately translates into the amplified activation of a wide range of innate apoptotic responses. We demonstrated that the altered molecular signaling pathway that originally results in RTX resistance could be circumvented and compensated by other DFMT-augmented pathways. Of note, our preliminary data provide proof-of-concept that CD20 cross-linking amplification emerges as an important strategy for overcoming RTX resistance. PMID- 29595952 TI - Controllable Synthesis of Gold Nanorod/Conducting Polymer Core/Shell Hybrids Toward in Vitro and in Vivo near-Infrared Photothermal Therapy. AB - Photothermal therapy (PTT) is a minimally invasive tumor treatment technology, and is regarded as a potential anticancer strategy because of its targeted destruction and low toxicity. Specifically, near-infrared light-induced PTT has attracted intriguing interest because of the high transparency of tissue, blood, and water. However, effective PTT generally requires the assistance of photothermal agents. Gold nanorods (GNRs) and conducting polymer are often used as photothermal materials because of their high absorption efficiency and photothermal conversion efficiency. Herein, we combined GNRs with poly( o methoxyaniline) (POMA, a polyaniline derivative) to form GNRs/POMA core/shell hybrids through the surfactant-assisted chemical oxidative polymerization route and studied their photothermal conversion properties. The configuration of GNRs/POMA core/shell hybrids has been precisely controlled through adjusting the monomer concentration, and the relationship between morphology and absorption band of GNRs/POMA core/shell hybrids has been revealed. Finally, the in vitro and in vivo experiments were performed, and the results indicated that the GNRs/POMA core/shell hybrids with optimized absorbance at around 808 nm exhibited the best performance on photothermal therapy under 808 nm NIR laser irradiation. PMID- 29595953 TI - Ion-Transport Design for High-Performance Na+-Based Electrochromics. AB - Sodium ion (Na+)-based electrochemical systems have been extensively investigated in batteries and supercapacitors and also can be quality candidates for electrochromic (EC) devices. However, poor diffusion kinetics and severe EC performance degradation occur during the intercalation/deintercalation processes because the ionic radii of Na+ are larger than those of conventional intercalation ions. Here, through intentional design of ion-transport channels in metal-organic frameworks (MOFs), Na+ serves as an efficient intercalation ion for incorporation into a nanostructured electrode with a high diffusion coefficient of approximately 10-8 cm2 s-1. As a result, the well-designed MOF-based EC device demonstrates desirable Na+ EC performance, including fast switching speed, multicolor switching, and high stability. A smart "quick response code" display is fabricated using a mask-free laser writing method for application in the "Internet of Things". In addition, the concept of ion transport pathway design can be widely adopted for fabricating high-performance ion intercalation materials and devices for consumer electronics. PMID- 29595955 TI - Peptidoglycan Modification by the Catalytic Domain of Streptococcus pneumoniae OatA Follows a Ping-Pong Bi-Bi Mechanism of Action. AB - Streptococcus pneumoniae among other Gram-positive pathogens produces O acetylated peptidoglycan using the enzyme OatA. This process occurs through the transfer of an acetyl group from a donor to the hydroxyl group of an acceptor sugar. While it has been established that this process involves the extracellular, catalytic domain of OatA ( SpOatAC), mechanistic insight is still unavailable. This study examined the enzymatic characteristics of SpOatAC catalyzed reactions through analysis of both pre-steady- and steady-state kinetics. Our findings clearly show that SpOatAC follows a ping-pong bi-bi mechanism of action involving a covalent acetyl-enzyme intermediate. The modified residue was verified to be the catalytic nucleophile, Ser438. The pH dependence of the enzyme kinetics revealed that a single ionizable group is involved, which is consistent with the participation of a His residue. Single-turnover kinetics of esterase activity demonstrated that k2 ? k3, revealing that the rate-limiting step for the hydrolytic reaction was the breakdown of the acetyl-enzyme intermediate with a half-life of >1 min. The previous assignment of Asn491 as an oxyanion hole residue was also confirmed as its replacement with Ala resulted in a 50-fold decrease in catalytic efficiency relative to that of wild-type SpOatAC. However, this loss of catalytic efficiency was mostly due to a large increase in KM, suggesting that Asn491 contributes more to substrate binding. PMID- 29595954 TI - MxiN Differentially Regulates Monomeric and Oligomeric Species of the Shigella Type Three Secretion System ATPase Spa47. AB - Shigella rely entirely on the action of a single type three secretion system (T3SS) to support cellular invasion of colonic epithelial cells and to circumvent host immune responses. The ATPase Spa47 resides at the base of the Shigella needle-like type three secretion apparatus (T3SA), supporting protein secretion through the apparatus and providing a likely means for native virulence regulation by Shigella and a much needed target for non-antibiotic therapeutics to treat Shigella infections. Here, we show that MxiN is a differential regulator of Spa47 and that its regulatory impact is determined by the oligomeric state of the Spa47 ATPase, with which it interacts. In vitro and in vivo characterization shows that interaction of MxiN with Spa47 requires the six N-terminal residues of Spa47 that are also necessary for stable Spa47 oligomer formation and activation. This interaction with MxiN negatively influences the activity of Spa47 oligomers while upregulating the ATPase activity of monomeric Spa47. Detailed kinetic analyses of monomeric and oligomeric Spa47 in the presence and absence of MxiN uncover additional mechanistic insights into the regulation of Spa47 by MxiN, suggesting that the MxiN/Spa47 species resulting from interaction with monomeric and oligomeric Spa47 are functionally distinct and that both could be involved in Shigella T3SS regulation. Uncovering regulation of Spa47 by MxiN addresses an important gap in the current understanding of how Shigella controls T3SA activity and provides the first description of differential T3SS ATPase regulation by a native T3SS protein. PMID- 29595957 TI - Kinetics and Product Formation during the Photooxidation of Butanol on Atmospheric Mineral Dust. AB - Mineral dust particles have photochemical properties that can promote heterogeneous reactions on their surfaces and therefore alter atmospheric composition. Even though dust photocatalytic nature has received significant attention recently, most studies have focused on inorganic trace gases. Here, we investigated how light changes the chemical interactions between butanol and Arizona test dust, a proxy for mineral dust, under atmospheric conditions. Butanol uptake kinetics were measured, exploring the effects of UV light irradiation intensity (0-1.4 mW/cm2), relative humidity (0-10%), temperature (283 298 K), and butanol initial concentration (20-55 ppb). The composition of the gas phase was monitored by a high-resolution proton-transfer-reaction mass spectrometer (PTR-ToF-MS) operating in H3O+ mode. Water was observed to play a significant role, initially reducing heterogeneous processing of butanol but enhancing reaction rates once it evaporated. Gas phase products were identified, showing that surface reactions of adsorbed butanol led to the emission of a variety of carbonyl containing compounds. Under actinic light these compounds will photolyze and produce hydroxyl radicals, changing dust processing from a sink of VOC into a source of reactive compounds. PMID- 29595956 TI - Quadruple H-Bonding Cross-Linked Supramolecular Polymeric Materials as Substrates for Stretchable, Antitearing, and Self-Healable Thin Film Electrodes. AB - Herein, we report a de novo chemical design of supramolecular polymer materials (SPMs-1-3) by condensation polymerization, consisting of (i) soft polymeric chains (polytetramethylene glycol and tetraethylene glycol) and (ii) strong and reversible quadruple H-bonding cross-linkers (from 0 to 30 mol %). The former contributes to the formation of the soft domain of the SPMs, and the latter furnishes the SPMs with desirable mechanical properties, thereby producing soft, stretchable, yet tough elastomers. The resulting SPM-2 was observed to be highly stretchable (up to 17 000% strain), tough (fracture energy ~30 000 J/m2), and self-healing, which are highly desirable properties and are superior to previously reported elastomers and tough hydrogels. Furthermore, a gold, thin film electrode deposited on this SPM substrate retains its conductivity and combines high stretchability (~400%), fracture/notch insensitivity, self-healing, and good interfacial adhesion with the gold film. Again, these properties are all highly complementary to commonly used polydimethylsiloxane-based thin film metal electrodes. Last, we proceed to demonstrate the practical utility of our fabricated electrode via both in vivo and in vitro measurements of electromyography signals. This fundamental understanding obtained from the investigation of these SPMs will facilitate the progress of intelligent soft materials and flexible electronics. PMID- 29595958 TI - Modeling Microalgae Productivity in Industrial-Scale Vertical Flat Panel Photobioreactors. AB - Potentially achievable biomass yields are a decisive performance indicator for the economic viability of mass cultivation of microalgae. In this study, a computer model has been developed and applied to estimate the productivity of microalgae for large-scale outdoor cultivation in vertical flat panel photobioreactors. Algae growth is determined based on simulations of the reactor temperature and light distribution. Site-specific weather and irradiation data are used for annual yield estimations in six climate zones. Shading and reflections between opposing panels and between panels and the ground are dynamically computed based on the reactor geometry and the position of the sun. The results indicate that thin panels (<=0.05 m) are best suited for the assumed cell density of 2 g L-1 and that reactor panels should face in north-south direction. Panel spacings of 0.4-0.75 m at a panel height of 1 m appear most suitable for commercial applications. Under these preconditions, yields of around 10 kg m-2 a-1 are possible for most locations in the U.S. Only in hot climates significantly lower yields have to be expected, as extreme reactor temperatures limit overall productivity. PMID- 29595959 TI - Zeolite-Templated Mesoporous Silicon Particles for Advanced Lithium-Ion Battery Anodes. AB - For the practical use of high-capacity silicon anodes in high-energy lithium based batteries, key issues arising from the large volume change of silicon during cycling must be addressed by the facile structural design of silicon. Herein, we discuss the zeolite-templated magnesiothermic reduction synthesis of mesoporous silicon (mpSi) (mpSi-Y, -B, and -Z derived from commercial zeolite Y, Beta, and ZSM-5, respectively) microparticles having large pore volume (0.4-0.5 cm3/g), wide open pore size (19-31 nm), and small primary silicon particles (20 35 nm). With these appealing mpSi particle structural features, a series of mpSi/C composites exhibit outstanding performance including excellent cycling stabilities for 500 cycles, high specific and volumetric capacities (1100-1700 mAh g-1 and 640-1000 mAh cm-3 at 100 mA g-1), high Coulombic efficiencies (approximately 100%), and remarkable rate capabilities, whereas conventional silicon nanoparticles (SiNP)/C demonstrate limited cycle life. These enhanced electrochemical responses of mpSi/C composites are further manifested by low impedance build-up, high Li ion diffusion rate, and small electrode thickness changes after cycling compared with those of SiNP/C composite. In addition to the outstanding electrochemical properties, the low-cost materials and high-yield processing make the mpSi/C composites attractive candidates for high-performance and high-energy Li-ion battery anodes. PMID- 29595960 TI - Life and Work of Stress Granules and Processing Bodies: New Insights into Their Formation and Function. AB - The dynamic formation of stress granules (SGs), processing bodies (PBs), and related RNA organelles regulates diverse cellular processes, including the coordination of functionally connected messengers, the translational regulation at the synapse, and the control of viruses and retrotransposons. Recent studies have shown that pyruvate kinase and other enzymes localize in SGs and PBs, where they become protected from stress insults. These observations may have implications for enzyme regulation and metabolic control exerted by RNA-based organelles. The formation of these cellular bodies is governed by liquid-liquid phase separation (LLPS) processes, and it needs to be strictly controlled to prevent pathogenic aggregation. The intracellular concentration of key metabolites, such as ATP and sterol derivatives, may influence protein solubility, thus affecting the dynamics of liquid organelles. LLPS in vitro depends on the thermal diffusion of macromolecules, which is limited inside cells, where the condensation and dissolution of membrane-less organelles are helped by energy-driven processes. The active transport by the retrograde motor dynein helps SG assembly, whereas the anterograde motor kinesin mediates SG dissolution; a tug of war between these two molecular motors allows transient SG formation. There is evidence that the efficiency of dynein-mediated transport increases with the number of motor molecules associated with the cargo. The dynein-dependent transport may be influenced by cargo size as larger cargos can load a larger number of motors. We propose a model based on this emergent property of dynein motors, which would be collectively stronger during SG condensation and weaker during SG breakdown, thus allowing kinesin-mediated dispersion.

AB - We report here a new ternary solvated (perylene-TCNB).2THF cocrystal, which can transform into binary perylene-TCNB cocrystal reversibly by successive desorption or absorption of THF solvent. As a consequence, macroscopic mechanical bending would be realized when repeated stimulation with THF solvent. The present results clearly demonstrated that solvent induced mechanical bending is driven by structural change at the molecular scale. Such solvatomechanical bending behavior is clearly revealed for the first time. PMID- 29595962 TI - Cross-Platform Cancer Cell Identification Using Telomerase-Specific Spherical Nucleic Acids. AB - Distinguishing tumor cells from normal cells holds the key to precision diagnosis and effective intervention of cancers. The fundamental difficulties, however, are the heterogeneity of tumor cells and the lack of truly specific and ideally universal cancer biomarkers. Here, we report a concept of tumor cell detection, bypassing the specific genotypic and phenotypic features of different tumor cell types and directly going toward the hallmark of cancer, uncontrollable growth. Combining spherical nucleic acids (SNAs) with exquisitely engineered molecular beacons (SNA beacons, dubbed SNAB technology) is capable of identifying tumor cells from normal cells based on the molecular phenotype of telomerase activity, largely bypassing the heterogeneity problem of cancers. Owing to the cell-entry capability of SNAs, the SNAB probe readily achieves tumor cell detection across multiple platforms, ranging from solution-based assay, to single cell imaging and in vivo solid tumor imaging (unlike PCR that is restricted to cell lysates). We envision the SNAB technology will impact cancer diagnosis, therapeutic response assessment, and image-guided surgery. PMID- 29595963 TI - Self-Powered Wind Sensor System for Detecting Wind Speed and Direction Based on a Triboelectric Nanogenerator. AB - The development of the Internet of Things has brought new challenges to the corresponding distributed sensor systems. Self-powered sensors that can perceive and respond to environmental stimuli without an external power supply are highly desirable. In this paper, a self-powered wind sensor system based on an anemometer triboelectric nanogenerator (a-TENG, free-standing mode) and a wind vane triboelectric nanogenerator (v-TENG, single-electrode mode) is proposed for simultaneously detecting wind speed and direction. A soft friction mode is adopted instead of a typical rigid friction for largely enhancing the output performance of the TENG. The design parameters including size, unit central angle, and applied materials are optimized to enhance sensitivity, resolution, and wide measurement scale. The optimized a-TENG could deliver an open-circuit voltage of 88 V and short-circuit current of 6.3 MUA, corresponding to a maximum power output of 0.47 mW (wind speed of 6.0 m/s), which is capable of driving electronics for data transmission and storage. The current peak value of the a TENG signal is used for analyzing wind speed for less energy consumption. Moreover, the output characteristics of a v-TENG are further explored, with six actual operation situations, and the v-TENG delivers fast response to the incoming wind and accurately outputs the wind direction data. As a wind sensor system, wind speed ranging from 2.7 to 8.0 m/s can be well detected (consistent with a commercial sensor) and eight regular directions can be monitored. Therefore, the fabricated wind sensor system has great potential in wireless environmental monitoring applications. PMID- 29595964 TI - In Situ Cellular Glycan Analysis. AB - Glycan decorates all mammalian cell surfaces through glycosylation, which is one of the most important post-modifications of proteins. Glycans mediate a wide variety of biological processes, including cell growth and differentiation, cell cell communication, immune response, pathogen interaction, and intracellular signaling events. Besides, tumor cells aberrantly express distinct sets of glycans, which can indicate different tumor onsets and progression processes. Thus, analysis of cellular glycans may contribute to understanding of glycan related biological processes and correlation of glycan patterns with disease states for clinical diagnosis and treatment. Although proteomics and glycomics have included great efforts for in vitro study of glycan structures and functions using lysis samples of cells or tissues, they cannot offer real-time qualitative or quantitative information, especially spatial distribution, of glycans on/in intact cells, which is important to the revelation of glycan-related biological events. Moreover, the complex lysis and separation procedures may bring unpredictable loss of glycan information. Focusing on the great urgency for in situ analysis of cellular glycans, our group developed a series of methods for in situ analysis of cellular glycans in the past 10 years. By construction of electrochemical glycan-recognizable probes, glycans on the cell surface can be quantified by direct or competitive electrochemical detection. Using multichannel electrodes or encoded lectin probes, multiple glycans on the cell surface can be dynamically monitored simultaneously. Through design of functional nanoprobes, the cell surface protein-specific glycans and intracellular glycan-related enzymes can be visualized by fluorescence or Raman imaging. Besides, some biological enzymes-based methods have been developed for remodeling or imaging of protein-specific glycans and other types of glycoconjugates, such as gangliosides. Through tracing the changes of glycan expression induced by drugs or gene interference, some glycan-related biological processes have been deduced or proved, demonstrating the reliability and practicability of the developed methods. This Account surveys the key technologies developed in this area, along with the discussion on the shortages of current methodology as well as the possible strategies to overcome those shortages. The future trend in this topic is also discussed. It is expected that this Account can provide a versatile arsenal for chemical and biological researchers to unravel the complex mechanisms involved in glycan-related biological processes and light new beacons in tumor diagnosis and treatment. PMID- 29595966 TI - Exploiting Charge-Transfer States for Maximizing Intersystem Crossing Yields in Organic Photoredox Catalysts. AB - A key feature of prominent transition-metal-containing photoredox catalysts (PCs) is high quantum yield access to long-lived excited states characterized by a change in spin multiplicity. For organic PCs, challenges emerge for promoting excited-state intersystem crossing (ISC), particularly when potent excited-state reductants are desired. Herein, we report a design exploiting orthogonal pi systems and an intermediate-energy charge-transfer excited state to maximize ISC yields (PhiISC) in a highly reducing ( E0* = -1.7 V vs SCE), visible-light absorbing phenoxazine-based PC. Simple substitution of N-phenyl for N-naphthyl is shown to dramatically increase PhiISC from 0.11 to 0.91 without altering catalytically important properties, such as E0*. PMID- 29595965 TI - Engineering an [FeFe]-Hydrogenase: Do Accessory Clusters Influence O2 Resistance and Catalytic Bias? AB - [FeFe]-hydrogenases, HydAs, are unique biocatalysts for proton reduction to H2. However, they suffer from a number of drawbacks for biotechnological applications: size, number and diversity of metal cofactors, oxygen sensitivity. Here we show that HydA from Megasphaera elsdenii (MeHydA) displays significant resistance to O2. Furthermore, we produced a shorter version of this enzyme (MeH HydA), lacking the N-terminal domain harboring the accessory FeS clusters. As shown by detailed spectroscopic and biochemical characterization, MeH-HydA displays the following interesting properties. First, a functional active site can be assembled in MeH-HydA in vitro, providing the enzyme with excellent hydrogenase activity. Second, the resistance of MeHydA to O2 is conserved in MeH HydA. Third, MeH-HydA is more biased toward proton reduction than MeHydA, as the result of the truncation changing the rate limiting steps in catalysis. This work shows that it is possible to engineer HydA to generate an active hydrogenase that combines the resistance of the most resistant HydAs and the simplicity of algal HydAs, containing only the H-cluster. PMID- 29595967 TI - Microgel-in-Microgel Biopolymer Delivery Systems: Controlled Digestion of Encapsulated Lipid Droplets under Simulated Gastrointestinal Conditions. AB - Structural design principles are increasingly being used to develop colloidal delivery systems for bioactive agents. In this study, oil droplets were encapsulated within microgel-in-microgel systems. Initially, a nanoemulsion was formed that contained small whey protein-coated oil droplets ( d43 = 211 nm). These oil droplets were then loaded into either carrageenan-in-alginate (O/MC/MA) or alginate-in-carrageenan (O/MA/MC) microgels. A vibrating nozzle encapsulation unit was used to form the smaller inner microgels ( d43 = 170-324 MUm), while a hand-held syringe was used to form the larger outer microgels ( d43 = 2200-3400 MUm). Calcium alginate microgels (O/MA) were more stable to simulated gastrointestinal tract (GIT) conditions than potassium carrageenan microgels (O/MC), which was attributed to the stronger cross-links formed by divalent calcium ions than the monovalent potassium ions. As a result, the microgel-in microgel systems had different gastrointestinal fates depending upon the nature of the external microgel phase; i.e., the O/MC/MA system was more resistant to rupture than the O/MA/MC system. The rate of lipid digestion under simulated small intestine conditions decreased in the following order: free oil droplets > O/MC > O/MA > O/MA/MC > O/MC/MA. This effect was attributed to differences in the integrity and dimensions of the microgels in the small intestine, because a hydrogel network surrounding the oil droplets inhibits lipid hydrolysis by lipase. The structured microgels developed in this study may have interesting applications for the protection or controlled release of bioactive agents.

AB - C-Glycoside derivatives are found in pharmaceuticals, glycoconjugates, probes, and other functional molecules. Thus, C-glycosidation of unprotected carbohydrates is of interest. Here the development of C-glycosidation reactions of unprotected di- and trisaccharide aldopyranoses with various ketones is reported. The reactions were performed using catalyst systems composed of pyrrolidine and boric acid under mild conditions. Carbohydrates used for the C glycosidation included lactose, maltose, cellobiose, 3'-sialyllactose, 6' sialyllactose, and maltotriose. Using ketones with functional groups, C glycosides ketones bearing the functional groups were obtained. The pyrolidine boric acid catalysis conditions did not alter the stereochemistry of non-C-C bond formation positions of the carbohydrates and led to the formation of the C glycosidation products with high diastereoselectivity. For the C-glycosidation of the carbohydrates under the pyrrolidine-boric acid-catalysis, the hydroxy group at the 6-position of the reacting aldopyranose was necessary to afford the product. Our analyses suggest that the carbohydrates form iminium ions with pyrrolidine and that boric acid forms B-O covalent bonds with the carbohydrates during the catalysis to forward the C-C bond formation.

AB - Sequence alignment of the four WW domains from human Nedd4-1 (neuronal precursor cell expressed developmentally down-regulated gene 4-1) reveals that the highest sequence diversity exists in loop I. Three residues in this type I beta-turn interact with the PPxY motif of the human epithelial Na+ channel (hENaC) subunits, indicating that peptide affinity is defined by the loop I sequence. The third WW domain (WW3*) has the highest ligand affinity and unlike the other three hNedd4-1 WW domains or other WW domains studied contains the highly statistically preferred proline at the ( i + 1) position found in beta-turns. In this report, molecular dynamics simulations and experimental data were combined to characterize loop I stability and dynamics. Exchange of the proline to the equivalent residue in WW4 (Thr) results in the presence of a predominantly open seven residue Omega loop rather than the type I beta-turn conformation for the wild-type apo-WW3*. In the presence of the ligand, the structure of the mutated loop I is locked into a type I beta-turn. Thus, proline in loop I ensures a stable peptide binding-competent beta-turn conformation, indicating that amino acid sequence modulates local flexibility to tune binding preferences and stability of dynamic interaction motifs.

AB - An enantioselective sulfenylation of beta-naphthols has been developed for the first time using a newly synthesized cinchona-derived thiourea as the catalyst and N-(arylthio) succinimide (or phthalimide) as an electrophilic sulfur source.

AB - Concentrated emulsions are widely used in the cosmetic, personal-care, and food industries to reduce storage and transportation costs and to provide desirable characteristics. The current study aimed to produce concentrated emulsions (50 wt % oil) using two natural emulsifiers, quillaja saponins and rhamnolipids. The impacts of emulsifier concentrations on the particle sizes, rheological properties, and stabilities of concentrated emulsions were evaluated. Emulsion particle sizes were negatively correlated with the concentrations of both quillaja saponins and rhamnolipids, and rhamnolipids were more effective in producing smaller droplets. Both emulsifiers formed stable concentrated emulsions against a series of environmental stresses, including various temperatures (30-90 degrees C), salt concentrations (<=200 mM NaCl), and pHs (pH 5-8). The rheology tests suggested that concentrated emulsions stabilized by quillaja saponins or rhamnolipids presented shear-thinning behaviors and had relatively low consistency coefficients.

AB - Five new dibenzocyclooctadiene lignans, longipedlignans A-E (1-5), five new tetrahydrobenzocyclooctabenzofuranones (6-10), and 18 known analogues (11-28) were isolated from the roots of Kadsura longipedunculata. Compounds 6-10 are new spirobenzofuranoid-dibenzocyclooctadiene-type lignans. Their structures and absolute configurations were established using a combination of MS, NMR, and electronic circular dichroism data. Spirobenzofuranoids 6 and 15 showed moderate hepatoprotective activity against N-acetyl- p-aminophenol-induced toxicity in HepG2 cells with cell survival rates at 10 MUM of 52.2% and 50.2%, respectively. PMID- 29595973 TI - Calculation of Ligand Dissociation Energies in Large Transition-Metal Complexes. AB - The accurate calculation of ligand dissociation (or equivalently, ligand binding) energies is crucial for computational coordination chemistry. Despite its importance, obtaining accurate ab initio reference data is difficult, and density functional methods of uncertain reliability are chosen for feasibility reasons. Here, we consider advanced coupled-cluster and multiconfigurational approaches to reinvestigate our WCCR10 set of 10 gas-phase ligand dissociation energies [ J. Chem. Theory Comput. 2014, 10, 3092]. We assess the potential multiconfigurational character of all molecules involved in these reactions with a multireference diagnostic [ Mol. Phys. 2017, 115, 2110] in order to determine where single-reference coupled-cluster approaches can be applied. For some reactions of the WCCR10 set, large deviations of density-functional results including semiclassical dispersion corrections from experimental reference data had been observed. This puzzling observation deserves special attention here, and we tackle the issue (i) by comparing to ab initio data that comprise dispersion effects on a rigorous first-principles footing and (ii) by a comparison of density-functional approaches that model dispersion interactions in various ways. For two reactions, species exhibiting nonnegligible static electron correlation were identified. These two reactions represent hard problems for electronic structure methods and also for multireference perturbation theories. However, most of the ligand dissociation reactions in WCCR10 do not exhibit static electron correlation effects, and hence, we may choose standard single-reference coupled-cluster approaches to compare with density-functional methods. For WCCR10, the Minnesota M06-L functional yielded the smallest mean absolute deviation of 13.2 kJ mol-1 out of all density functionals considered (PBE, BP86, BLYP, TPSS, M06-L, PBE0, B3LYP, TPSSh, and M06-2X) without additional dispersion corrections in comparison to the coupled-cluster results, and the PBE0-D3 functional produced the overall smallest mean absolute deviation of 4.3 kJ mol-1. The agreement of density-functional results with coupled-cluster data increases significantly upon inclusion of any type of dispersion correction. It is important to emphasize that different density-functional schemes available for this purpose perform equally well. The coupled-cluster dissociation energies, however, deviate from experimental results on average by 30.3 kJ mol-1. Possible reasons for these deviations are discussed. PMID- 29595975 TI - Coupled Cluster Theory Combined with Reference Interaction Site Model Self Consistent Field Explicitly Including Spatial Electron Density Distribution. AB - Calculating the geometry and energy of a molecule in a solution is one of the most important tasks in chemistry. However, performing an accurate calculation in a solution is still a difficult task because the electronic structure and solute solvent interactions are required to be accurately evaluated with an efficient computational cost. To overcome this difficulty, we proposed the coupled cluster with single and double excitations and perturbative triple excitations combined with the reference interaction site model (RISM) by employing our fitting approach. Our method correctly reproduced the relative stabilities of 1,2,3 triazole, isonicotinic acid, cytosine, and 6-chloro-2-pyridone in the aqueous phase, whereas the dielectric continuum model provided incorrect results for isonicotinic acid and 6-chloro-2-pyridone. Our method provided accurate results because the RISM captured the local solvation structure, such as hydrogen bonds.

AB - In part as a result of the production of an enterotoxin, Staphylococcus aureus is a highly infectious pathogen and is a considerable threat to food hygiene and safety. Clinical mastitis models were established by S. aureus nipple-tube perfusion. The influence of mastitis on the mammary-gland-tissue proteomic profile was investigated using isobaric tags for relative and absolute quantitation. In this study, healthy and mastitic tissues from different mammary gland areas of the same dairy cows were screened, and differentially expressed proteins were identified. Bioinformatic analysis identified proteins related to the inflammation and immunization of dairy cows. Histology, immunoblotting, and immunohistochemical-staining analyses were used to determine the expression of PGLYRP1 and PTX3 proteins in the acquired mammary-gland-tissue samples. PGLYRP1 and PTX3 in mastitic mammary glands may be associated with tissue damage and immune responses to late stages of infection. This further contributes to the understanding of the molecular theory of the treatment of mastitis caused by S. aureus.

AB - We have studied the reactions of o-quinone methide precursors with imino ethers. The reaction provides a versatile route to substituted 1,3-benzoxazines. The proposed reaction mechanism involves the generation of the o-quinone methide intermediates, imino-Diels-Alder reaction, and elimination. This cascade process is a rare example of the participation of imino ethers as dienophiles. PMID- 29595978 TI - Understanding the Mechanism Stabilizing Intermediate Spin States in Fe(II) Porphyrin. AB - Spin fluctuations in Fe(II)-porphyrins are at the heart of heme-proteins functionality. Despite significant progress in porphyrin chemistry, the mechanisms that rule spin state stabilization remain elusive. Here, it is demonstrated by using multiconfigurational quantum chemical approaches, including the novel Stochastic-CASSCF method, that electron delocalization between the metal center and the pi system of the macrocycle differentially stabilizes the triplet spin states over the quintet. This delocalization takes place via charge transfer excitations, involving the pi system of the macrocycle and the out-of plane iron d orbitals, key linking orbitals between metal and macrocycle. Through a correlated breathing mechanism the 3d electrons can make transitions toward the pi orbitals of the macrocycle. This guarantees a strong coupling between the on site radial correlation on the metal and electron delocalization. Opposite-spin 3d electrons of the triplet can effectively reduce electron repulsion in this manner. Constraining the out-of-plane orbitals from breathing hinders delocalization and reverses the spin ordering. The breathing mechanism is made effective by strong electron correlation effects in the pi system of the macrocycle. Reducing the correlation treatment on the macrocycle to second-order only also reverses the spin ordering. High order (beyond second-order) correlation on the macrocycle reduces the energetic cost of the additional electron to a sufficient extent to stabilize the triplet state. Our results find a qualitative analogue in six resonance structures involving the metal center in the Fe2+ and Fe3+ oxidation states.

AB - Lactate dehydrogenase (LDH) catalyzes the reduction of pyruvate to lactate by using NADH. LDH kinetics has been proposed to be dependent on the dynamics of a loop over the active site. Kramers' theory has been useful in the study of enzyme catalysis dependent on large structural dynamics. In this work, LDH kinetics was studied in the presence of trehalose and at different temperatures. In the absence of trehalose, temperature increase raised exponentially the LDH Vmax and revealed a sigmoid transition of Km toward a low-affinity state similar to protein unfolding. Notably, LDH Vmax diminished when in the presence of trehalose, while pyruvate affinity increased and the temperature-mediated binding site transition was hindered. The effect of trehalose on kcat was viscosity dependent as described by Kramers' theory since Vmax correlated inversely with the viscosity of the medium. As a result, activation energy ( Ea) for pyruvate reduction was dramatically increased by trehalose presence. This work provides experimental evidence that the dynamics of a structural component in LDH is essential for catalysis, i.e., the closing of the loop on the active site. While the trehalose mediated-increased of pyruvate affinity is proposed to be due to the compaction and/or increase of structural order at the binding site. PMID- 29595979 TI - Spatial and Spin Symmetry Breaking in Semidefinite-Programming-Based Hartree-Fock Theory. AB - The Hartree-Fock problem was recently recast as a semidefinite optimization over the space of rank-constrained two-body reduced-density matrices (RDMs) [ Phys. Rev. A 2014 , 89 , 010502(R) ]. This formulation of the problem transfers the nonconvexity of the Hartree-Fock energy functional to the rank constraint on the two-body RDM. We consider an equivalent optimization over the space of positive semidefinite one-electron RDMs (1-RDMs) that retains the nonconvexity of the Hartree-Fock energy expression. The optimized 1-RDM satisfies ensemble N representability conditions, and ensemble spin-state conditions may be imposed as well. The spin-state conditions place additional linear and nonlinear constraints on the 1-RDM. We apply this RDM-based approach to several molecular systems and explore its spatial (point group) and spin ( S2 and S3) symmetry breaking properties. When imposing S2 and S3 symmetry but relaxing point group symmetry, the procedure often locates spatial-symmetry-broken solutions that are difficult to identify using standard algorithms. For example, the RDM-based approach yields a smooth, spatial-symmetry-broken potential energy curve for the well-known Be-H2 insertion pathway. We also demonstrate numerically that, upon relaxation of S2 and S3 symmetry constraints, the RDM-based approach is equivalent to real-valued generalized Hartree-Fock theory.

AB - Metal-organic framework (MOF) thin films show unmatched promise as smart membranes and photocatalytic coatings. However, their nucleation and growth resulting from intricate molecular assembly processes are not well understood yet are crucial to control the thin film properties. Here, we directly observe the nucleation and growth behavior of HKUST-1 thin films by real-time in situ AFM at different temperatures in a Cu-BTC solution. In combination with ex situ infrared (nano)spectroscopy, synthesis at 25 degrees C reveals initial nucleation of rapidly growing HKUST-1 islands surrounded by a continuously nucleating but slowly growing HKUST-1 carpet. Monitoring at 13 and 50 degrees C shows the strong impact of temperature on thin film formation, resulting in (partial) nucleation and growth inhibition. The nucleation and growth mechanisms as well as their kinetics provide insights to aid in future rational design of MOF thin films.

AB - All-solid-state rechargeable batteries embody the promise for high energy density, increased stability, and improved safety. However, their success is impeded by high resistance for mass and charge transfer at electrode-electrolyte interfaces. Li deficiency has been proposed as a major culprit for interfacial resistance, yet experimental evidence is elusive due to the challenges associated with noninvasively probing the Li distribution in solid electrolytes. In this Letter, three-dimensional 7Li magnetic resonance imaging (MRI) is employed to examine Li distribution homogeneity in solid electrolyte Li10GeP2S12 within symmetric Li/Li10GeP2S12/Li batteries. 7Li MRI and the derived histograms reveal Li depletion from the electrode-electrolyte interfaces and increased heterogeneity of Li distribution upon electrochemical cycling. Significant Li loss at interfaces is mitigated via facile modification with a poly(ethylene oxide)/bis(trifluoromethane)sulfonimide Li salt thin film. This study demonstrates a powerful tool for noninvasively monitoring the Li distribution at the interfaces and in the bulk of all-solid-state batteries as well as a convenient strategy for improving interfacial stability.

PMID- 29595981 TI - Detergent Desorption of Membrane Proteins Exhibits Two Kinetic Phases. AB - Gradual dissociation of detergent molecules from water-insoluble membrane proteins culminates in protein aggregation. However, the time-dependent trajectory of this process remains ambiguous because the signal-to-noise ratio of most spectroscopic and calorimetric techniques is drastically declined by the presence of protein aggregates in solution. We show that by using steady-state fluorescence polarization (FP) spectroscopy the dissociation of the protein detergent complex (PDC) can be inspected in real time at detergent concentrations below the critical micelle concentration. This article provides experimental evidence of the coexistence of two distinct phases of the dissociations of detergent monomers from membrane proteins. We first noted a slow detergent predesolvation process, which was accompanied by a relatively modest change in the FP anisotropy, suggesting a small number of dissociated detergent monomers from the proteomicelles. This predesolvation phase was followed by a fast detergent desolvation process, which was highlighted by a major alteration in the FP anisotropy. The durations and rates of these phases were dependent on both the detergent concentration and the interfacial PDC interactions. Further development of this approach might lead to the creation of a new semiquantitative method for the assessment of the kinetics of association and dissociation of proteomicelles.

AB - Exosomes, released from various cell types, serve as vehicles of intercellular communication. Rearranged anaplastic lymphoma kinase (ALK) has been detected in exosomes released from cancer cells in ALK-positive nonsmall cell lung cancer (NSCLC), however, the functional consequence of ALK in exosomes has not been studied. This study aims to address whether exosomal ALK release is affected by stress, and whether exosomal ALK can modulate survival of recipient cells in vitro and in vivo. Exosomes, isolated from ALK-containing H3122 cells with (Exo Apo) or without (Exo-Ctrl) irradiation treatment, were transferred to recipient H3122 cells in vitro or mouse xenograft in vivo. Western blot, flow cytometry, MTT, and xenograft were employed to respectively assess activation of the ALK pathway, apoptosis, cell viability, and tumor growth. Exo-Apo contained much higher levels of phosphorylated ALK (p-ALK) than that of Exo-Ctrl, and it activated AKT, STAT3, and the ERK pathway in recipient H3122 cells. ALK-specific inhibitors, including Crizotinib, Ceritinib, and TAE684, exhibited less effects on H3122 cells preincubated with Exo-Apo than on those treated with Exo-Ctrl in either inhibition of cell viability or promotion of apoptosis. Moreover, in an H3122 xenograft model, the Exo-Apo treatment resulted in a greater tumor growth and less sensitivity to Ceritinib than the Exo-Ctrl treatment. The ALK protein cargo in exosomes could be a key element to drive tumor growth and compromise therapeutic efficacy of ALK inhibitors for ALK-positive NSCLC. PMID- 29595985 TI - Phosphonic Acids on an Atomically Defined Oxide Surface: The Binding Motif Changes with Surface Coverage. AB - We have studied the anchoring mechanism of a phosphonic acid on an atomically defined oxide surface. Using time-resolved infrared reflection absorption spectroscopy, we investigated the reaction of deuterated phenylphosphonic acid (DPPA, C6H5PO3D2) with an atomically defined Co3O4(111) surface in situ during film growth by physical vapor deposition. We show that the binding motif of the phosphonate anchor group changes as a function of coverage. At low coverage, DPPA binds in the form of a chelating tridentate phosphonate, while a transition to a chelating bidentate occurs close to monolayer saturation coverage. However, the coverage-dependent change in the binding motif is not associated with a major change of the molecular orientation, suggesting that the rigid phosphonate linker always maintains the DPPA in a strongly tilted orientation irrespective of the surface coverage.

AB - An efficient method has been successfully developed to achieve the asymmetric C-H functionalization of indoles in the carbocyclic ring via organocatalysis, and a variety of tetrahydropyranoindoles were synthesized in good yields with excellent stereoselectivities. Further study on thermodynamic calculations indicated that the process was promoted by generating more thermodynamically stable products. This strategy, together with traditional C-3 functionalization of hydroxyindoles, could realize the switchable, regiodivergent asymmetric modification of indoles.

AB - Understanding the properties of the electrical double layer (EDL) is one of the interdisciplinary topics that plays a key role in the investigation of numerous natural and artificial systems. We present experimental evidence about the influence of the nature of the alkali metal cations on the EDL capacitance for two model electrodes, Pt(111) and Au(111), in 0.05 M AMClO4 ( AM: Li+, Na+, K+, Rb+, Cs+) electrolytes using impedance spectroscopy measurements. Our data show that counterintuitively the differential EDL capacitance of both electrodes measured close to their potentials of zero charge increased linearly in the presence of alkali metal cations as Li+ < Na+ < K+ < Rb+ < Cs+. We also estimated the effective concentrations of these cations at the EDL, which appeared ~80 times higher than their bulk concentrations. We believe that these findings should be of importance for theoretical modeling of the EDL and better understanding and faster design of new functional systems for numerous applications. PMID- 29595988 TI - Observation and Manipulation of Visible Edge Plasmons in Bi2Te3 Nanoplates. AB - Noble metals, like Ag and Au, are the most intensively studied plasmonic materials in the visible range. Plasmons in semiconductors, however, are usually believed to be in the infrared wavelength region due to the intrinsic low carrier concentrations. Herein, we observe the edge plasmon modes of Bi2Te3, a narrow band gap semiconductor, in the visible spectral range using photoemission electron microscopy (PEEM). The Bi2Te3 nanoplates excited by 400 nm femtosecond laser pulses exhibit strong photoemission intensities along the edges, which follow a cos4 dependence on the polarization state of incident beam. Because of the phase retardation effect, plasmonic response along different edges can be selectively exited. The thickness-dependent photoemission intensities exclude the spin-orbit induced surface states as the origin of these plasmonic modes. Instead, we propose that the interband transition-induced nonequilibrium carriers might play a key role. Our results not only experimentally demonstrate the possibility of visible plasmons in semiconducting materials but also open up a new avenue for exploring the optical properties of topological insulator materials using PEEM.

AB - We here describe a new Cu-catalyzed annulation cascade of alkyne-tethered alpha bromocarbonyls with common alkynes for the synthesis of various heteropolycycle frameworks, including 1 H-benzo[ de]quinolin-2(3 H)-ones, 4 H-dibenzo[ de,g]quinolin-5(6 H)-one, and benzo[ de]chromen-2(3 H)-one, which were constructed with high selectivity. This was achieved by two-component annulation cascades, rather than atom-transfer radical cyclization (ATRC), with alkyne tethered alpha-bromocarbonyls for one-step accessing heteropolycycles via C-Br bond split, intramolecular cyclization, intermolecular [4 + 2] annulation, and aryl C(sp2)-H functionalization cascades.

AB - We show, by performing exact time-independent quantum molecular scattering calculations, that the quality of the ground electronic state global potential energy surface appears to be of utmost importance in accurately obtaining even as strongly averaged quantities as kinetic rate constants. The oxygen isotope exchange reaction, 18O + 32O2, motivated by the understanding of a complex long standing problem of isotopic ozone anomalies in the stratosphere and laboratory experiments, is explored in this context. The thermal rate constant for this key reaction is now in quantitative agreement with all experimental data available to date. A significant recent progress at the frontier of three research domains, advanced electronic structure calculations, ultrasensitive spectroscopy, and quantum scattering calculations, has therefore permitted a breakthrough in the theoretical modeling of this crucial collision process from first principles. PMID- 29595992 TI - Improving Lateral Flow Assay Performance Using Computational Modeling. AB - The performance, field utility, and low cost of lateral flow assays (LFAs) have driven a tremendous shift in global health care practices by enabling diagnostic testing in previously unserved settings. This success has motivated the continued improvement of LFAs through increasingly sophisticated materials and reagents. However, our mechanistic understanding of the underlying processes that drive the informed design of these systems has not received commensurate attention. Here, we review the principles underpinning LFAs and the historical evolution of theory to predict their performance. As this theory is integrated into computational models and becomes testable, the criteria for quantifying performance and validating predictive power are critical. The integration of computational design with LFA development offers a promising and coherent framework to choose from an increasing number of novel materials, techniques, and reagents to deliver the low cost, high-fidelity assays of the future. PMID- 29595991 TI - The Clinical Effects of Manipulative Therapy in People with Chronic Obstructive Pulmonary Disease. AB - OBJECTIVES: This study aimed to determine the effects of manipulative therapies (MT), including spinal manipulation, and diaphragmatic release techniques on lung function, exercise capacity, symptoms, and health-related quality of life (HRQOL) in people with chronic obstructive pulmonary disease (COPD). DESIGN: Systematic review. PARTICIPANTS: People diagnosed with COPD. INTERVENTION: Randomized controlled trials of MT (either with or without pulmonary rehabilitation [PR]) compared to other treatments (soft tissue [ST] therapy or sham therapy) applied in people with COPD were identified following the search of seven databases. Two reviewers independently assessed study quality and extracted data. OUTCOME MEASURES: Lung function, exercise capacity, symptoms, and HRQOL. RESULTS: Four studies were included, with a total of 68 participants. The heterogeneity between treatments prevented meta-analysis. There was no beneficial effect on spirometry measures of lung function with MT. MT combined with PR improved exercise capacity by 48-49 m more than ST therapy plus PR. Less dyspnea was reported with MT and ST therapy compared to ST therapy alone (p = 0.01), but there was no effect on HRQOL, or symptoms of anxiety or depression. CONCLUSIONS: In people with COPD, MT (either with or without PR) improved functional exercise capacity, but had no effect on lung function, or HRQOL. Further research is required to determine the underlying mechanism of this treatment approach and its relationship to exercise capacity. PMID- 29595993 TI - Factors Predictive of Healing in Large Rotator Cuff Tears: Is It Possible to Predict Retear Preoperatively? AB - BACKGROUND: Many studies have identified risk factors that cause retear after rotator cuff repair. However, it is still questionable whether retears can be predicted preoperatively. PURPOSE: To determine the risk factors related to retear after arthroscopic rotator cuff repair and to evaluate whether it is possible to predict the occurrence of retear preoperatively. STUDY DESIGN: Case control study; Level of evidence, 3. METHODS: This study enrolled 112 patients who underwent arthroscopic rotator cuff repair with single-row technique for a large-sized tear, defined as a tear with a mediolateral length of 3 to 5 cm. All patients underwent routine magnetic resonance imaging (MRI) at 9 months postoperatively to assess tendon integrity. The sample included 61 patients (54.5%) in the healed group and 51 (45.5%) in the retear group. RESULTS: In multivariate analysis, the independent predictors of retears were supraspinatus muscle atrophy ( P < .001) and fatty infiltration of the infraspinatus ( P = .027), which could be preoperatively measured by MRI. A significant difference was found between the two groups in sex, the acromiohumeral interval, tendon tension, and preoperative or intraoperative mediolateral tear length and musculotendinous junction position in univariate analysis. However, these variables were not independent predictors in multivariate analysis. The cutoff values of occupation ratio of supraspinatus and fatty infiltration of the infraspinatus were 43% and grade 2, respectively. The occupation ratio of supraspinatus <43% and grade >=2 fatty infiltration of the infraspinatus were the strongest predictors of retear, with an area under the curve of 0.908, sensitivity of 98.0%, and specificity of 83.6% (accuracy = 90.2%). CONCLUSION: In patients with large rotator cuff tears, it was possible to predict the retear before rotator cuff repair regardless of intraoperative factors. The retear could be predicted most effectively when the occupation ratio of supraspinatus was <43% or the fatty infiltration of infraspinatus was grade >=2. Predicting retear preoperatively may help surgeons determine proper treatment and predict the postoperative prognosis.

AB - INTRODUCTION: This study utilized a cross-sectional qualitative and quantitative interview-based survey to capture the infant feeding practices and barriers to exclusive breastfeeding for women in methadone maintenance therapy. Participants were recruited from an opioid dependence treatment center in an urban setting in the Southeastern United States. MATERIALS AND METHODS: A convenience sample of women in treatment (n = 30) were interviewed using an adapted instrument designed to capture decisions and intentions to formula feed or breastfeed; support from friends and family; hospital experience; support from healthcare personnel; and maternal knowledge of breastfeeding while taking methadone. RESULTS: The majority of women in the sample initiated breastfeeding, but only 10% continued for >1 month. Challenges related to infant hospital stay posed a significant barrier. Two-thirds of infants remained hospitalized after the mother was discharged. Out of the 24 women who initiated breastfeeding, 11 reported that they discontinued because of issues related to infant's neonatal intensive care unit (NICU) stay. Eleven women reported that their healthcare providers did not discuss breastfeeding with them. Women who were encouraged to breastfeed by healthcare staff were more likely to breastfeed for longer durations. CONCLUSIONS: Women in treatment for opioid dependence both desire and attempt to establish breastfeeding, but encounter significant challenges, including long NICU stays and lack of support and education, that compromise their success. These findings should inform the development of future programs or interventions geared toward increasing breastfeeding initiation, support, and duration among women who give birth to babies while in treatment for opioid addiction.

AB - A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols, free from commercial interest or influence, for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. PMID- 29595996 TI - Return to Play After Hip Arthroscopy: A Systematic Review and Meta-analysis. AB - BACKGROUND: The use of arthroscopic treatment for intra-articular hip pathology has demonstrated improved patient-reported outcomes (PROs) with a lower rate of complications, reoperation, and patient morbidity as compared with traditional methods. Although the use of this minimally invasive approach has increased in prevalence, no evidence-based return-to-play (RTP) criteria have been developed to ensure an athlete's preparedness for sporting activities. PURPOSE: To determine if there exists sufficient evidence in the literature to support an RTP protocol and functional assessment after hip arthroscopy, as well as to assess the mean rate and duration of RTP. STUDY DESIGN: Systematic review and meta analysis. METHODS: The search terms "hip arthroscopy," "return to play," and 10 related terms were searched in PubMed, Cochrane Library, Scopus, and Web of Science, yielding 263 articles. After screening, 22 articles were included. RTP timeline, rehabilitation protocols, and conditional criteria measures were assessed with previously established criteria. Pooled estimates were calculated for RTP rate and duration, and weighted mean scores were determined for PROs. RESULTS: A total of 1296 patients with 1442 total hips were identified. Although 54.5% (12 of 22) of studies did not provide a guideline for RTP duration after hip arthroscopy, 36.4% (8 of 22) recommended a duration of 4 months, while 9.1% (2 of 22) recommended 3 months. The most frequently described postoperative rehabilitation protocols were weightbearing guidelines (15 studies) and passive motion exercises (9 studies). Only 2 studies satisfied the criteria for a sufficient RTP protocol, and 3 provided a specific replicable test for RTP. The mean RTP duration was 7.4 months (95% CI, 6.1-8.8 months), and the return rate was 84.6% (95% CI, 80.4%-88.8%; P = .008) at a mean +/- SD follow-up of 25.8 +/- 2.4 months. Mean modified Harris Hip Score (mHHS) improved from 63.1 to 84.1 postoperatively (+33.3%), while Non-arthritic Hip Score improved from 61.7 to 86.8 (+40.7%). A lower preoperative mHHS was significantly associated with a higher postoperative improvement ( r = -0.95, P = .0003). CONCLUSION: Significant variability exists in RTP protocols among institutions owing to a lack of standardization. Despite a high overall rate of RTP and improvement in PROs after hip arthroscopy, the majority of rehabilitation protocols are not evidence based and rely on expert opinion. No validated functional test currently exists to assess RTP. PMID- 29595998 TI - Single-Molecule View of Small RNA-Guided Target Search and Recognition. AB - Most everyday processes in life involve a necessity for an entity to locate its target. On a cellular level, many proteins have to find their target to perform their function. From gene-expression regulation to DNA repair to host defense, numerous nucleic acid-interacting proteins use distinct target search mechanisms. Several proteins achieve that with the help of short RNA strands known as guides. This review focuses on single-molecule advances studying the target search and recognition mechanism of Argonaute and CRISPR (clustered regularly interspaced short palindromic repeats) systems. We discuss different steps involved in search and recognition, from the initial complex prearrangement into the target-search competent state to the final proofreading steps. We focus on target search mechanisms that range from weak interactions, to one- and three-dimensional diffusion, to conformational proofreading. We compare the mechanisms of Argonaute and CRISPR with a well-studied target search system, RecA.

AB - Substantial natural gas liquids recovery from tight shale formations has produced a significant boon for the US chemical industry. As fracking technology improves, shale liquids may represent the same for other geographies. As with any major industry disruption, the advent of shale resources permits both the chemical industry and the community an excellent opportunity to have open, foundational discussions on how both public and private institutions should research, develop, and utilize these resources most sustainably. This review summarizes current chemical industry processes that use ethane and propane from shale gas liquids to produce the two primary chemical olefins of the industry: ethylene and propylene. It also discusses simplified techno-economics related to olefins production from an industry perspective, attempting to provide a mutually beneficial context in which to discuss the next generation of sustainable olefin process development. PMID- 29596000 TI - Nanoscale Optical Microscopy and Spectroscopy Using Near-Field Probes. AB - Light-matter interactions can provide a wealth of detailed information about the structural, electronic, optical, and chemical properties of materials through various excitation and scattering processes that occur over different length, energy, and timescales. Unfortunately, the wavelike nature of light limits the achievable spatial resolution for interrogation and imaging of materials to roughly lambda/2 because of diffraction. Scanning near-field optical microscopy (SNOM) breaks this diffraction limit by coupling light to nanostructures that are specifically designed to manipulate, enhance, and/or extract optical signals from very small regions of space. Progress in the SNOM field over the past 30 years has led to the development of many methods to optically characterize materials at lateral spatial resolutions well below 100 nm. We review these exciting developments and demonstrate how SNOM is truly extending optical imaging and spectroscopy to the nanoscale. PMID- 29595997 TI - Structure and Immune Recognition of the HIV Glycan Shield. AB - Vaccine design efforts against the human immunodeficiency virus (HIV) have been greatly stimulated by the observation that many infected patients eventually develop highly potent broadly neutralizing antibodies (bnAbs). Importantly, these bnAbs have evolved to recognize not only the two protein components of the viral envelope protein (Env) but also the numerous glycans that form a protective barrier on the Env protein. Because Env is heavily glycosylated compared to host glycoproteins, the glycans have become targets for the antibody response. Therefore, considerable efforts have been made in developing and validating biophysical methods to elucidate the complex structure of the Env-spike glycoprotein, with its combination of glycan and protein epitopes. We illustrate here how the application of robust biophysical methods have transformed our understanding of the structure and function of the HIV Env spike and stimulated innovation in vaccine design strategies that takes into account the essential glycan components Expected final online publication date for the Annual Review of Biophysics Volume 47 is May 20, 2018.

PMID- 29596001 TI - Identification of Candidate Genes Involved in the Salt Tolerance of Date Palm (Phoenix dactylifera L.) Based on a Yeast Functional Bioassay. AB - Although date palm is a relatively salt-tolerant plant, the molecular basis of this tolerance is complex and poorly understood. Therefore, this study aimed to identify the genes involved in salinity tolerance using a basic yeast functional bioassay. To achieve this, a date palm cDNA library was overexpressed in Saccharomyces cerevisiae cells. The expression levels of selected genes that make yeast cells tolerant to salt were subsequently validated in the leaf and root tissues of date palm seedlings using a quantitative PCR method. About 6000 yeast transformant cells were replica printed and screened on a synthetic minimal medium containing 1.0 M of NaCl. The screening results showed the presence of 62 salt-tolerant transformant colonies. Sequence analysis of the recombinant yeast plasmids revealed the presence of a group of genes with potential salt-tolerance functions, such as aquaporins (PIP), serine/threonine protein kinases (STKs), ethylene-responsive transcription factor 1 (ERF1), and peroxidases (PRX). The expression pattern of the selected genes endorsed the hypothesis that these genes may be involved in salinity tolerance, as they showed a significant (p < 0.05) overexpression trend in both the leaf and root tissues in response to salinity. The genes identified in this project are suitable candidates for the further functional characterization of date palms. PMID- 29596002 TI - Imaging Bacterial Cell Wall Biosynthesis. AB - Peptidoglycan is an essential component of the cell wall that protects bacteria from environmental stress. A carefully coordinated biosynthesis of peptidoglycan during cell elongation and division is required for cell viability. This biosynthesis involves sophisticated enzyme machineries that dynamically synthesize, remodel, and degrade peptidoglycan. However, when and where bacteria build peptidoglycan, and how this is coordinated with cell growth, have been long standing questions in the field. The improvement of microscopy techniques has provided powerful approaches to study peptidoglycan biosynthesis with high spatiotemporal resolution. Recent development of molecular probes further accelerated the growth of the field, which has advanced our knowledge of peptidoglycan biosynthesis dynamics and mechanisms. Here, we review the technologies for imaging the bacterial cell wall and its biosynthesis activity. We focus on the applications of fluorescent d-amino acids, a newly developed type of probe, to visualize and study peptidoglycan synthesis and dynamics, and we provide direction for prospective research. PMID- 29596003 TI - The Oxysterol-Binding Protein Cycle: Burning Off PI(4)P to Transport Cholesterol. AB - To maintain an asymmetric distribution of ions across membranes, protein pumps displace ions against their concentration gradient by using chemical energy. Here, we describe a functionally analogous but topologically opposite process that applies to the lipid transfer protein (LTP) oxysterol-binding protein (OSBP). This multidomain protein exchanges cholesterol for the phosphoinositide phosphatidylinositol 4-phosphate [PI(4)P] between two apposed membranes. Because of the subsequent hydrolysis of PI(4)P, this counterexchange is irreversible and contributes to the establishment of a cholesterol gradient along organelles of the secretory pathway. The facts that some natural anti-cancer molecules block OSBP and that many viruses hijack the OSBP cycle for the formation of intracellular replication organelles highlight the importance and potency of OSBP mediated lipid exchange. The architecture of some LTPs is similar to that of OSBP, suggesting that the principles of the OSBP cycle-burning PI(4)P for the vectorial transfer of another lipid-might be general. PMID- 29596004 TI - Knowledge, Attitude, and Practice of Yoga in Medical Students: Assessment of Anthropometry and Lifestyle Factors. AB - Medical students often experience significant stress during their undergraduate training. Evidence has shown short-term yoga to be effective in decreasing stress in students. This study aimed to assess knowledge about, attitude toward, and practice of (KAP) yoga among medical students. A secondary objective was to analyze their dietary habits and physical activity. Participants consisted of 224 medical students aged 18-23 years in pre- and paraclinical groups. A closed-ended KAP questionnaire was used to collect data. Anthropometric measurements were taken. Results showed that paraclinical students (70.5%) favorably perceived the health benefits of yoga. Nearly three-fourths of study subjects had previously practiced yoga; greater numbers intended to practice yoga in the future. About 95.5% of the preclinical students who had done yoga had discontinued the practice. Perceived barriers to the practice of yoga were lack of time, insufficient facilities, lack of company, and lack of interest. Consideration of the undergraduates' lifestyle revealed that 50.4% of preclinical students did not exercise, and they routinely consumed more junk food with fewer servings of fresh fruits/salads. Preclinical students exhibited higher BMI and waist circumference compared to paraclinical students. Findings suggest that knowledge of and attitude regarding yoga were good among medical undergraduates. PMID- 29596005 TI - Improved Self-Acceptance, Quality of Life, and Stress Level from Participation in a Worksite Yoga Foundations Program: A Pilot Study. AB - Yoga is increasing in popularity in the United States and across the globe. However, most yoga programs are provided outside the worksite; although many companies offer worksite wellness programs, at present there is limited documentation regarding the potential benefits of participating in a worksite yoga program. Therefore, the purpose of this project was to examine the potential effect of a worksite yoga program on self-acceptance, quality of life, and perceived stress. A prospective cohort pilot study that examined a structured worksite yoga program was designed and tailored to individuals new to yoga. The 8 week Yoga Foundations program was conducted at an academic medical center's worksite wellness center with 86 subjects. Outcome measures were the 36-item Self Acceptance Scale; a six-item quality-of-life measure that assesses overall, social, mental, physical, emotional, and spiritual well-being; and the ten-item Perceived Stress Scale. Participants demonstrated significant improvement in their overall self-acceptance ( p < 0.001), quality of life ( p < 0.001), and perceived stress ( p < 0.001) levels. They also highly rated the yoga instructors and the weekly format of the program. Participation in a Yoga Foundations program was associated with improvements in self-acceptance, quality of life and stress levels in worksite wellness center members. Future studies should use randomized designs and examine other wellness domains to learn more about the potential benefits of worksite yoga programs. PMID- 29596006 TI - Accuracy of Prehospital Identification of Stroke in a Large Stroke Belt Municipality. AB - OBJECTIVE: Strokes are a leading cause of morbidity and mortality in the United States, especially in the "stroke belt" of the southeast. Up to 65% of stroke patients access care by calling 9-1-1. The primary objective of this study is to measure the accuracy of emergency medical dispatchers (EMD) and paramedics, in the prehospital identification of stroke. METHODS: The study was based at Grady Emergency Medical Services, which is Atlanta, Georgia's public emergency medical services (EMS) provider. A retrospective analysis of all medically related 9-1-1 calls to Grady EMS classified as "stroke" between January 1, 2012, and December 31, 2012 was performed. A database was created using deterministic linkage between records from Grady EMS, Grady Hospital Emergency Department (ED), and the Grady Hospital Stroke Registry. Patients excluded were less than 18 years of age, had previous or concurrent head injuries, were transferred from another inpatient facility, and/or had incomplete patient records in any one of the three databases. Descriptive analysis, linear regression, and logistic multivariable regression were performed to discover the accuracy of stroke identification and contributory prehospital factors. RESULTS: A total of 548 patients were included: 475 were transported with EMS impression of stroke and 73 with an impression other than stroke. The median age was 59 years, 87.4% were black, and 52.6% were female. Paramedics adhered to all seven elements of the Grady EMS stroke protocol in 76.4% (n = 363) of suspected stroke cases. Sensitivity and positive predictive value for paramedic stroke identification was 76.2% and 49.3%, respectively, and for EMD, was 48.9% and 24%, respectively. Identification of hemorrhagic strokes had a relatively lower sensitivity. Paramedics were more likely to positively identify strokes when the Cincinnati Prehospital Stroke Scale (CPSS) screen was positive, or when classified by EMD as stroke. Paramedics were less likely to identify stroke in female patients. Paramedics' diagnostic accuracy was similar regardless of their adherence to the EMS stroke care protocol. CONCLUSIONS: EMD and EMS personnel in a large city in the Southeastern United States, with high stroke prevalence, had a relatively high sensitivity in identifying acute stroke patients. Paramedic accuracy was augmented by positive CPSS screening and by EMD recognition of stroke. PMID- 29596007 TI - Outpatient physical therapy cardiovascular assessment: Physical therapist perspective and experience. AB - BACKGROUND: Physical therapists are recognized healthcare providers who play an important role in cardiovascular disease prevention. Heart rate (HR) and blood pressure (BP) are important parameters in cardiovascular risk assessment; however, physical therapists do not usually integrate them into clinical practice. Therefore, this study aimed to examine the current practice and opinion of outpatient physical therapists toward HR and BP measurements in clinics. METHODS: A 12-item survey questionnaire was distributed to outpatient physical therapists. Five senior staff from different specialties, including orthopedic, neurology, pediatric, cardiopulmonary, and sport specialties, participated in a focus group interview to gather their opinions. RESULTS: In total, 285 (56%: male) physical therapists participated. Only 68 (24%) measured HR and BP; of these, 27 (41%) used manual sphygmomanometers. Nearly one-fifth reported that cardiovascular adverse events, such as syncope and chest pain, occurred during therapeutic exercise of their patients and were the highest among the sport and orthopedic physical therapists. Most physical therapists felt that measuring cardiovascular indices is not their job and does not add value to their treatment plan. CONCLUSION: Majority of the physical therapists were not measuring HR and BP during clinical assessment, although some reported cardiovascular adverse events occurring in their patients. PMID- 29596008 TI - Psychotropic medications for highly vulnerable children. AB - INTRODUCTION: At least 20% of children in the U.S. are highly vulnerable because they lack healthcare and protection. Several factors produce vulnerability: trauma, disruptions of parenting, poverty, involvement in the juvenile justice and/or child welfare systems, residence in restrictive settings, and problems related to developmental disabilities. These children receive psychotropic medications at high rates, raising numerous concerns. Areas covered: The authors begin this review with a description of the population of highly vulnerable children. They then follow this with a review of the effectiveness and side effects of psychotropic medications for their most common diagnoses, using the highest-quality systematic reviews identified by multiple database searches. Expert opinion: Highly vulnerable children receive numerous psychotropic medications with high rates of polypharmacy, off-label use, and long-term use, typically in the absence of adjunctive psychosocial interventions. The current evidence contravenes these trends. Future studies of psychotropic medications in vulnerable children should include long-term effectiveness trials and polypharmacy in conjunction with evidence-based, family-centered, psychosocial treatments. PMID- 29596009 TI - Decreased Time from 9-1-1 Call to PCI among Patients Experiencing STEMI Results in a Decreased One Year Mortality. AB - BACKGROUND: The impact on mortality due to prompt recognition of ST-segment Elevation Myocardial Infarction (STEMI) patients by EMS has not been well described. The objective of this study was to describe the association between the time interval, 9-1-1 call to percutaneous intervention (PCI), and mortality at one year. METHODS: This retrospective analysis included patients that were transported by EMS as a "code STEMI" and underwent PCI. Total time from 9-1-1 call to PCI was calculated for each patient and was the independent variable of interest. Each patient's mortality status at one year was the outcome variable, collected by querying medical records and the national death index. Confounding variables were abstracted from hospital records. Logistic regression was conducted to determine the likelihood of survival given differences in time to PCI. RESULTS: A total of 550 patients were included in the analyses of which 68% were male with an average age 59.8 (SD 12.8). Mean reperfusion time was 81.8 min (SD 20.0) and was significantly lower in patients alive at one year (80.8 min, SD 19.7) vs. deceased at one year (93.9 min, SD 19.6), respectively. Odds of survival at one year decreased by 3% (OR 0.97; 95% CI 0.96-0.99) for every one minute increase in time to PCI. This relationship practically represents a 30% increase in mortality for every 10 minute delay from 9-1-1 call to PCI. CONCLUSION: The model produced suggests that a linear relationship exists between time to PCI and mortality in the prehospital environment with the probability of survival decreasing significantly as time to PCI increases. PMID- 29596010 TI - Whole body vibration on people with sequelae of polio. AB - PURPOSE: The purpose was to explore the feasibility of whole body vibration (WBV) on polio survivors with/without post-polio syndrome (PPS) by studying its effects on walking speed (10-m walk test), endurance (2-min walk test), pain severity/interference (Brief Pain Inventory [BPI]), sleep quality (Pittsburg Sleep Quality Index), fatigue (Fatigue Severity Scale), leg strength (manual muscle testing and hand-held dynamometry), and muscle cramping (written logs). METHODS: Fifteen individuals completed the study, participating in eight sessions in two 4-week blocks. Participants started with ten 1-min vibration bouts/session, increasing to 20 min. Low (amplitude 4.53 mm, g force 2.21) and higher (amplitude 8.82 mm, g force 2.76) intensity blocked intervention occurred in random order crossover design. Blinded testing ensued before/after intervention blocks and at follow-up. RESULTS: No study-related adverse events occurred. Participants starting first with higher intensity intervention improved in walking speed (p = 0.017). BPI pain severity significantly improved (p = 0.049) after higher intensity intervention. No significant changes were found after low intensity vibration or in other outcome measures. CONCLUSIONS: WBV appears to be a safe exercise for this population. Long-term use in polio survivors needs to be researched, particularly in reducing barriers to participation to promote the physical aspects of health. PMID- 29596011 TI - Slow Infusion of Recombinant Adeno-Associated Viruses into the Mouse Cerebrospinal Fluid Space. AB - Recombinant adeno-associated viruses (rAAVs) are the leading in vivo gene delivery platform, and have been extensively studied in gene therapy targeting various tissues, including the central nervous system (CNS). A single-bolus rAAV injection to the cerebrospinal fluid (CSF) space has been widely used to target the CNS, but it suffers from several drawbacks, such as leakage to peripheral tissues. Here, a protocol is described using an osmotic pump to infuse rAAV slowly into the mouse CSF space. Compared to the single-bolus injection technique, pump infusion can lead to higher CNS transduction and lower transduction in the peripheral tissues. PMID- 29596012 TI - Utility of natriuretic peptides to assess and manage patients with heart failure receiving angiotensin receptor blocker/neprilysin inhibitor therapy. AB - Levels of natriuretic peptides (NPs), such as B-type NP (BNP) and the N-terminal fragment of its prohormone (NT-proBNP), are well-established biomarkers for patients with heart failure (HF). Although these biomarkers have consistently demonstrated their value in the diagnosis and prognostication of HF, their ability to help clinicians in making treatment decisions remains debated. Moreover, some new HF drugs can affect concentrations of NPs, such as the prevention of BNP degradation by angiotensin receptor/neprilysin inhibitors (ARNIs), and may present a challenge in the interpretation of levels of BNP. Use of NT-proBNP measurement has been suggested in the context of ARNI therapy because its concentrations are not affected by neprilysin inhibition. As biomarkers are reconsidered in the context of ARNI therapy, cutoff levels and the effects of individual patient characteristics, such as renal function and age, on biomarker concentrations should be reassessed. PMID- 29596013 TI - The 2016 Earthquake in Ecuador: Zika Outbreak After a Natural Disaster. AB - The objective of this work was to examine the spread of the Zika virus after the destructive impact of the earthquake of April 2016 along the coast of Ecuador. Using a difference-in-difference estimation method and a unique dataset to track Zika cases at the national level, we estimated the impact of the earthquake on the reported cases of Zika in the affected region. Our results suggest that the earthquake increased the reported cases of Zika by 0.509 per epidemiologic week (data per 10,000 population), and we argue that the destroyed built environment along with other factors created a disease focus, where the virus spread easily. Because of its potential complications and devastating long-term effects, Zika represents a national threat. After a natural disaster, the health authorities, together with a multidisciplinary team and the wider community, all have an urgent responsibility to collaborate to minimize the health risks to the population. PMID- 29596014 TI - Lower tendon stiffness in very old compared with old individuals is unaffected by short-term resistance training of skeletal muscle. AB - Aging negatively affects collagen-rich tissue, like tendons, but in vivo tendon mechanical properties and the influence of physical activity after the 8th decade of life remain to be determined. This study aimed to compare in vivo patellar tendon mechanical properties in moderately old (old) and very old adults and the effect of short-term resistance training. Twenty old (9 women, 11 men, >65 yr) and 30 very old (11 women, 19 men, >83 yr) adults were randomly allocated to heavy resistance training (HRT) or no training (CON) and underwent testing of in vivo patellar tendon (PT) mechanical properties and PT dimensions before and after a 3-mo intervention. Previous measurements of muscle properties, blood parameters, and physical activity level were included in the analysis. Data from 9 old HRT, 10 old CON, 14 very old CON, and 12 old HRT adults were analyzed. In addition to lower quadriceps muscle strength and cross-sectional area (CSA), we found lower PT stiffness and Young's modulus ( P < 0.001) and a trend toward the lower mid-portion PT-CSA ( P = 0.09) in very old compared with old subjects. Daily step count was also lower in very old subjects ( P < 0.001). Resistance training improved muscle strength and cross-sectional area equally in old and very old subjects ( P < 0.05) but did not affect PT mechanical properties or dimension. We conclude that PT material properties are reduced in very old age, and this may likely be explained by reduced physical activity. Three months of resistance training however, could not alter PT mechanical properties in very old individuals. NEW & NOTEWORTHY This research is the first to quantify in vivo tendon mechanical properties in a group of very old adults in their eighties. Patellar tendon stiffness was lower in very old (87 yr on average) compared with moderately old (68 yr on average) individuals. Reduced physical activity with aging may explain some of the loss in tendon stiffness, but regular heavy resistance training for 3 mo was not sufficient to change tendon mechanical properties. PMID- 29596015 TI - Continuous negative abdominal pressure: mechanism of action and comparison with prone position. AB - We recently reported that continuous negative abdominal pressure (CNAP) could recruit dorsal atelectasis in experimental lung injury and that oxygenation improved at different transpulmonary pressure values compared with increases in airway pressure (Yoshida T, Engelberts D, Otulakowski G, Katira BH, Post M, Ferguson ND, Brochard L, Amato MBP, Kavanagh BP. Am J Respir Crit Care Med 197: 534-537, 2018). The mechanism of recruitment with CNAP is uncertain, and its impact compared with a commonly proposed alternative approach to recruitment, prone positioning, is not known. We hypothesized that CNAP recruits lung by decreasing the vertical pleural pressure (Ppl) gradient (i.e., difference between dependent and nondependent Ppl), thought to be one mechanism of action of prone positioning. An established porcine model of lung injury (surfactant depletion followed by ventilator-induced lung injury) was used. CNAP was applied using a plexiglass chamber that completely enclosed the abdomen at a constant negative pressure (-5 cmH2O). Lungs were recruited to maximal positive end-expiratory pressure (PEEP; 25 cmH2O) and deflated in steps of PEEP (2 cmH2O, 10 min each). CNAP lowered the Ppl in dependent but not in nondependent lung, and therefore, in contrast to PEEP, it narrowed the vertical Ppl gradient. CNAP increased respiratory system compliance and oxygenation and appeared to selectively displace the posterior diaphragm caudad (computerized tomography images). Compared with prone position without CNAP, CNAP in the supine position was associated with higher arterial partial pressure of oxygen and compliance, as well as greater homogeneity of ventilation. The mechanism of action of CNAP appears to be via selective narrowing of the vertical gradient of Ppl. CNAP appears to offer physiological advantages over prone positioning. NEW & NOTEWORTHY Continuous negative abdominal pressure reduces the vertical gradient in (dependent vs. nondependent) pleural pressure and increases oxygenation and lung compliance; it is more effective than prone positioning at comparable levels of positive end-expiratory pressure. PMID- 29596017 TI - Mechanisms for the increased fatigability of the lower limb in people with type 2 diabetes. AB - Fatiguing exercise is the basis of exercise training and a cornerstone of management of type 2 diabetes mellitus (T2D); however, little is known about the fatigability of limb muscles and the involved mechanisms in people with T2D. The purpose of this study was to compare fatigability of knee extensor muscles between people with T2D and controls without diabetes and determine the neural and muscular mechanisms for a dynamic fatiguing task. Seventeen people with T2D [ten men and seven women: 59.6 (9.0) yr] and twenty-one age-, body mass index-, and physical activity-matched controls [eleven men and ten women: 59.5 (9.6) yr] performed one hundred twenty high-velocity concentric contractions (one contraction/3 s) with a load equivalent to 20% maximal voluntary isometric contraction (MVIC) torque with the knee extensors. Transcranial magnetic stimulation (TMS) and electrical stimulation of the quadriceps were used to assess voluntary activation and contractile properties. People with T2D had larger reductions than controls in power during the fatiguing task [42.8 (24.2) vs. 26.4 (15.0)%; P < 0.001] and MVIC torque after the fatiguing task [37.6 (18.2) vs. 26.4 (12.1)%; P = 0.04]. People with T2D had greater reductions than controls in the electrically evoked twitch amplitude after the fatiguing task [44.0 (20.4) vs. 35.4 (12.1)%, respectively; P = 0.01]. However, the decrease in voluntary activation was similar between groups when assessed with electrical stimulation [12.1 (2.6) vs. 12.4 (4.4)% decrease; P = 0.84] and TMS ( P = 0.995). A greater decline in MVIC torque was associated with larger reductions of twitch amplitude ( r2 = 0.364, P = 0.002). Although neural mechanisms contributed to fatigability, contractile mechanisms were responsible for the greater knee extensor fatigability in men and women with T2D compared with healthy controls. NEW & NOTEWORTHY Transcranial magnetic stimulation and percutaneous muscle stimulation were used to determine the contributions of neural and contractile mechanisms of fatigability of the knee extensor muscles after a dynamic fatiguing task in men and women with type 2 diabetes (T2D) and healthy age-, body mass index-, and physical activity-matched controls. Although neural and contractile mechanisms contributed to greater fatigability of people with T2D, fatigability was primarily associated with impaired contractile mechanisms and glycemic control. PMID- 29596016 TI - Chronic interval exercise training prevents BKCa channel-mediated coronary vascular dysfunction in aortic-banded miniswine. AB - Conventional treatments have failed to improve the prognosis of heart failure with preserved ejection fraction (HFpEF) patients. Thus, the purpose of this study was to determine the therapeutic efficacy of chronic interval exercise training (IT) on large-conductance Ca2+-activated K+ (BKCa) channel-mediated coronary vascular function in heart failure. We hypothesized that chronic interval exercise training would attenuate pressure overload-induced impairments to coronary BKCa channel-mediated function. A translational large-animal model with cardiac features of HFpEF was used to test this hypothesis. Specifically, male Yucatan miniswine were divided into three groups ( n = 7/group): control (CON), aortic banded (AB)-heart failure (HF), and AB-interval trained (HF-IT). Coronary blood flow, vascular conductance, and vasodilatory capacity were measured after administration of the BKCa channel agonist NS-1619 both in vivo and in vitro in the left anterior descending coronary artery and isolated coronary arterioles, respectively. Skeletal muscle citrate synthase activity was decreased and left ventricular brain natriuretic peptide levels increased in HF vs. CON and HF-IT animals. A parallel decrease in NS-1619-dependent coronary vasodilatory reserve in vivo and isolated coronary arteriole vasodilatory responsiveness in vitro were observed in HF animals compared with CON, which was prevented in the HF-IT group. Although exercise training prevented BKCa channel mediated coronary vascular dysfunction, it did not change BKCa channel alpha subunit mRNA, protein, or cellular location (i.e., membrane vs. cytoplasm). In conclusion, these results demonstrate the viability of chronic interval exercise training as a therapy for central and peripheral adaptations of experimental heart failure, including BKCa channel-mediated coronary vascular dysfunction. NEW & NOTEWORTHY Conventional treatments have failed to improve the prognosis of heart failure with preserved ejection fraction (HFpEF) patients. Our findings show that chronic interval exercise training can prevent BKCa channel-mediated coronary vascular dysfunction in a translational swine model of chronic pressure overload-induced heart failure with relevance to human HFpEF.

AB - : Brodmann Maeder, Monika, Hermann Brugger, Matiram Pun, Giacomo Strapazzon, Tomas Dal Cappello, Marco Maggiorini, Peter Hackett, Peter Baartsch, Erik R. Swenson, Ken Zafren (STAR Core Group), and the STAR Delphi Expert Group. The STARdata reporting guidelines for clinical high altitude research. High AltMedBiol. 19:7-14, 2018. AIMS: The goal of the STAR (STrengthening Altitude Research) initiative was to produce a uniform set of key elements for research and reporting in clinical high-altitude (HA) medicine. The STAR initiative was inspired by research on treatment of cardiac arrest, in which the establishment of the Utstein Style, a uniform data reporting protocol, substantially contributed to improving data reporting and subsequently the quality of scientific evidence. MATERIALS AND METHODS: The STAR core group used the Delphi method, in which a group of experts reaches a consensus over multiple rounds using a formal method. We selected experts in the field of clinical HA medicine based on their scientific credentials and identified an initial set of parameters for evaluation by the experts. RESULTS: Of 51 experts in HA research who were identified initially, 21 experts completed both rounds. The experts identified 42 key parameters in 5 categories (setting, individual factors, acute mountain sickness and HA cerebral edema, HA pulmonary edema, and treatment) that were considered essential for research and reporting in clinical HA research. An additional 47 supplemental parameters were identified that should be reported depending on the nature of the research. CONCLUSIONS: The STAR initiative, using the Delphi method, identified a set of key parameters essential for research and reporting in clinical HA medicine.

AB - The tendon is a mechanosensitive tissue, but little is known about how mechanical stimulation selectively signals tenogenic differentiation and neo-tendon formation. In this study, we compared the impact of uniaxial and biaxial mechanical loading on tendon-derived stem cells (TDSCs). Our data show that there are variations in cell signaling and cell differentiation of mouse TDSCs in response to uniaxial and biaxial loading in monolayer culture. Whereas uniaxial loading induced TDSCs toward tenogenic and osteogenic differentiation, biaxial loading induced osteogenic, adipogenic, and chondrogenic differentiation of TDSCs. Furthermore, by applying uniaxial loading on 3-dimensional (3D) TDSC constructs, tenogenic-specific differentiation and neo-tendon formation were observed, results that were replicated in human TDSCs. We also showed that uniaxial loading induced PKB (AKT) phosphorylation (pAKT), whereas biaxial loading induced pERK. Most importantly, we found that inhibition of the PI3K/AKT signaling pathway could attenuate tenogenic differentiation and tendon formation in 3D TDSC constructs subjected to uniaxial loading. Taken together, our study highlights the importance of appropriate mechanobiological stimulation in 3D cell niches on tendon-like tissue formation and demonstrates that uniaxial mechanical loading plays an essential role in tenogenic differentiation and tendon formation by activating the PI3K/AKT signaling pathway.-Wang, T., Thien, C., Wang, C., Ni, M., Gao, J., Wang, A., Jiang, Q., Tuan, R. S., Zheng, Q., Zheng, M. H. 3D uniaxial mechanical stimulation induces tenogenic differentiation of tendon derived stem cells through a PI3K/AKT signaling pathway. PMID- 29596024 TI - Autocrine actions of prolactin contribute to the regulation of lactotroph function in vivo. AB - Prolactin (PRL), whose principal role is regulation of lactation, is mainly synthesized and secreted by lactotroph anterior pituitary cells. Its signaling is exerted via a transmembrane PRL receptor (PRLR) expressed in a wide variety of tissues, including the anterior pituitary. Dopamine, which is secreted by tuberoinfundibular hypothalamic neurons, is the major inhibitory regulator of prolactin secretion. Although PRL is well established to stimulate hypothalamic dopamine secretion, thereby exerting a negative feedback regulation on its own release, autocrine or paracrine actions of PRL on lactotroph cells have also been suggested. Within the pituitary, PRL may inhibit both lactotroph proliferation and secretion, but in vivo evaluation of these putative functions is limited. To determine whether the autocrine actions of prolactin have a significant role in the physiologic function of lactotrophs in vivo, we examined the consequences of conditional deletion of Prlr in lactotroph cells using a novel mouse line with loxP sites flanking the Prlr gene ( Prlrlox/lox) and Cre-recombinase (Cre) expressed under the control of the pituitary-specific Prl promoter. Prlrlox/lox/Prl-Cre mice have normal PRL levels and did not develop any pituitary lactotroph adenoma, even at 20 mo of age. Nevertheless, Prlrlox/lox/Prl-Cre mice displayed an increased dopaminergic inhibitory tone compared with control Prlrlox/lox mice. These results elegantly confirm an autocrine/paracrine feedback of PRL on lactotroph cells in vivo, which can be fully compensated by an intact hypothalamic feedback system.-Bernard, V., Lamothe, S., Beau, I., Guillou, A., Martin, A., Le Tissier, P., Grattan, D., Young, J., Binart, N. Autocrine actions of prolactin contribute to the regulation of lactotroph function in vivo. PMID- 29596023 TI - Inflammation-induced lymphatic architecture and bone turnover changes are ameliorated by irisin treatment in chronic inflammatory bowel disease. AB - Inflammatory bowel disease (IBD) is a chronic disease with gastrointestinal dysfunction as well as comorbidities such as inflammation-induced bone loss and impaired immune response. Current treatments for IBD all have negative, potentially severe side effects. We aimed to test whether exogenous treatment with irisin, a novel immunomodulatory adipomyokine, could ameliorate IBD-induced lymphatic and bone alterations. Irisin treatment improved both gut and bone outcomes by mitigating inflammation and restoring structure. In the gut, IBD caused colonic lymphatic hyperproliferation into the mucosal and submucosal compartments. This proliferation in the rodent model is akin to what is observed in IBD patient case studies. In bone, IBD increased osteoclast surface and decreased bone formation. Both gut and osteocytes in bone exhibited elevated levels of TNF-alpha and receptor activator of NF-kappaB ligand (RANKL) protein expression. Exogenous irisin treatment restored normal colonic lymphatic architecture and increased bone formation rate concurrent with decreased osteoclast surfaces. After irisin treatment, gut and osteocyte TNF-alpha and RANKL protein expression levels were no different from vehicle controls. Our data indicate that the systemic immunologic changes that occur in IBD are initiated by damage in the gut and likely linked through the lymphatic system. Additionally, irisin is a potential novel intervention mitigating both local inflammatory changes in the gut and distant changes in bone.-Narayanan, S. A., Metzger, C. E., Bloomfield, S. A., Zawieja, D. C. Inflammation-induced lymphatic architecture and bone turnover changes are ameliorated by irisin treatment in chronic inflammatory bowel disease. PMID- 29596025 TI - Palliative Care Consultation in Advanced Chronic Kidney Disease with Pain. AB - BACKGROUND: There is little data on pain management in patients with advanced chronic kidney disease (CKD) who have opted for palliative care. OBJECTIVE: We investigated the prevalence, severity and management of pain in advanced CKD patients attending Renal Palliative Care out-patient clinics under our Division. METHODS: Consecutive patients referred to the Renal Palliative Care Clinics at two hospitals under our Division from July 2012 to June 2016 were included. All the patients were managed according to a multi-disciplinary protocol led by palliative care specialists, including serial assessments with the Edmonton Symptom Assessment System. MEASUREMENTS: Response to pain management was defined as a difference by 2 points or more, and factors predictive of response were assessed by logistic regression. RESULTS: Data from 253 patients were analyzed. Of them 107 patients (42%) experienced pain symptoms: 45 patients (42.1%) rated their pain as mild (score 0-3), 51 (47.7%) as moderate (NRS score 4-6), and 11 (10.2%) as severe (score 7-10) by using numerical rating scale. The response rate to pain management was 53.2%. Neuropathic pain was a predictor for lack of response. DISCUSSION: Pain is common in advanced CKD patients receiving palliative care. While this seems to have been underrecognized, the symptom is potentially amenable to management. We recommend routine assessment of pain burden in this patient population. PMID- 29596027 TI - Optimization aspects of the biological nitrogen removal process in a full-scale twin sequencing batch reactor (SBR) system in series treating landfill leachate. AB - Despite the fact that biological nitrogen removal (BNR) process has been studied in detail in laboratory- and pilot-scale sequencing batch reactor (SBR) systems treating landfill leachate, a limited number of research works have been performed in full-scale SBR plants regarding nitrification and denitrification. In the current study, a full-scale twin SBR system in series of 700 m3 (350 m3 each) treating medium-age landfill leachate was evaluated in terms of its carbon and nitrogen removal efficiency in the absence and presence of external carbon source, i.e., glycerol from biodiesel production. Both biodegradable organic carbon and ammonia were highly oxidized [biochemical oxygen demand (BOD5) and total Kjehldahl nitrogen (TKN) removal efficiencies above 90%], whereas chemical oxygen demand (COD) removal efficiency was slightly above 40%, which is within the range reported in the literature for pilot-scale SBRs. As the consequence of the high recalcitrant organic fraction of the landfill leachate, dissimilatory nitrate reduction was restricted in the absence of crude glycerol, although denitrification was improved by electron donor addition, resulting in TN removal efficiencies above 70%. Experimental data revealed that the second SBR negligibly contributed to BNR process, since carbon and ammonia oxidation completion was achieved in the first SBR. On the other hand, the low VSS/SS ratio, due to the lack of primary sedimentation, highly improved sludge settleability, resulting in sludge volume indices (SVI) below 30 mL g-1. PMID- 29596026 TI - Environmental factors influencing landfill gas biofiltration: Lab scale study on methanotrophic bacteria growth. AB - The post-management of landfills represents an important challenge for landfill gas treatment. Traditional systems (energy recovery, flares, etc.) present technical problems in treating flow with low methane (CH4) concentrations. The objective of this study was to isolate methanotrophic bacteria from a field-scale biofilter in order to study the bacteria in laboratories and evaluate the environmental factors that mostly influence Microbial Aerobic Methane Oxidation (MAMO). The soil considered was sampled from the biofilter located in the landfill of Venosa (Basilicata Region, Italy) and it was mainly composed of wood chips and compost. The results showed that methanotrophic microorganisms are mainly characterized by a slow growth and a significant sensitivity to CH4 levels. Temperature and nitrogen (N) also have a very important role on their development. On the basis of the results, biofilters for biological CH4 oxidation can be considered a viable alternative to mitigate CH4 emissions from landfills. PMID- 29596028 TI - Expression and functional analysis of three nicosulfuron-degrading enzymes from Bacillus subtilis YB1. AB - To investigate the degradation activity of the manganese ABC transporter, vegetative catalase 1 and acetoin dehydrogenase E1 from Bacillus subtilis YB1, the proteins were prokaryotically expressed and purified. Assay results showed that the three enzymes were able to degrade nicosulfuron (2- (4,6 dimethoxypyrimidine-2-pyrimidinylcarbamoylaminosulfonyl) -N,N dimethylnicotinamide), with vegetative catalase 1 exhibiting the highest activity. To further examine the degradation pathway, the degradation products of the three enzymes and the YB1 strain were detected by liquid chromatography-mass spectrometry(LC-MS). The nicosulfuron degradation products of the three enzymes were consistent with those of the YB1 strain, indicating the presence of two pathways: one due to cleavage of sulfonylurea bridges and ring-opening of 1-(4,6 dimethoxy-pyrimidin-2-yl)-3-(2-methyliminomethanesulfonyl-acetyl)-ureaas the pyrimidine ring, yielding the product; and the another due to cleavage of a sulfonylurea bridge, yielding 4,6-dihydroxy pyrimidine (111 m/z), 2-ylamine -4,6 dimethoxy pyrimidine and ((4-(dimethycarbamoyl)pyridine-2-yl)sulfonyl)carbamic acid as products, which were further degraded to 4,6-dihydroxy pyrimidine and N,N dimethyl-2-sulfamoyl-isonicotinamide. The above results reveal a major contribution of extracellular enzymes to the degradation of nicosulfuron by the YB1 strain. Our data help in elucidation of the mechanism of nicosulfuron bio degradation and may facilitate the construction of engineered strains. PMID- 29596029 TI - Phase II Study of Crizotinib in East Asian Patients With ROS1-Positive Advanced Non-Small-Cell Lung Cancer. AB - Purpose Approximately 1% to 2% of non-small-cell lung cancers (NSCLCs) harbor a c ros oncogene 1 ( ROS1) rearrangement. Crizotinib, an inhibitor of anaplastic lymphoma kinase (ALK), ROS1, and MET, has shown marked antitumor activity in a small expansion cohort of patients with ROS1-positive advanced NSCLC from an ongoing phase I study. We assessed the efficacy and safety of crizotinib in the largest cohort of patients with ROS1-positive advanced NSCLC. Patients and Methods This phase II, open-label, single-arm trial enrolled East Asian patients with ROS1-positive (assessed through validated AmoyDx assay [Amoy Diagnostics, Xiamen, China] at three regional laboratories) advanced NSCLC who had received three or fewer lines of prior systemic therapies. Patients were to receive oral crizotinib at a starting dose of 250 mg twice daily and continued treatment until Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1-defined progression (by independent radiology review [IRR]), unacceptable toxicity, or withdrawal of consent. The primary end point was objective response rate (ORR) by IRR. Results In the efficacy and safety analyses, 127 patients were included, with 49.6% still receiving treatment at data cutoff. ORR by IRR was 71.7% (95% CI, 63.0% to 79.3%), with 17 complete responses and 74 partial responses. ORRs were similar irrespective of the number of prior lines of therapy, and responses were durable (median duration of response, 19.7 months; 95% CI, 14.1 months to not reached). Median progression-free survival by IRR was 15.9 months (95% CI, 12.9 to 24.0 months). No new safety signals associated with crizotinib were reported. Conclusion This study demonstrated clinically meaningful benefit and durable responses with crizotinib in East Asian patients with ROS1-positive advanced NSCLC. Crizotinib was generally well tolerated, with a safety profile consistent with previous reports. PMID- 29596031 TI - Incorporating Genuine Prior Information about Between-Study Heterogeneity in Random Effects Pairwise and Network Meta-analyses. AB - BACKGROUND: Pairwise and network meta-analyses using fixed effect and random effects models are commonly applied to synthesize evidence from randomized controlled trials. The models differ in their assumptions and the interpretation of the results. The model choice depends on the objective of the analysis and knowledge of the included studies. Fixed effect models are often used because there are too few studies with which to estimate the between-study SD from the data alone. OBJECTIVES: The aim of this study was to propose a framework for eliciting an informative prior distribution for the between-study SD in a Bayesian random effects meta-analysis model to genuinely represent heterogeneity when data are sparse. METHODS: We developed an elicitation method using external information, such as empirical evidence and expert beliefs, on the "range" of treatment effects to infer the prior distribution for the between-study SD. We also developed the method to be implemented in R. RESULTS: The 3-stage elicitation approach allows uncertainty to be represented by a genuine prior distribution to avoid making misleading inferences. It is flexible to what judgments an expert can provide and is applicable to all types of outcome measures for which a treatment effect can be constructed on an additive scale. CONCLUSIONS: The choice between using a fixed effect or random effects meta analysis model depends on the inferences required and not on the number of available studies. Our elicitation framework captures external evidence about heterogeneity and overcomes the assumption that studies are estimating the same treatment effect, thereby improving the quality of inferences in decision making. PMID- 29596030 TI - Potential Value of YAP Staining in Rhabdomyosarcoma. AB - Rhabdomyosarcoma (RMS) is a common malignancy of soft tissue, subclassified as alveolar (ARMS), pleomorphic (PRMS), spindle cell/sclerosing (SRMS), and embryonal (ERMS) types. The Yes-associated protein (YAP) is a member of the Hippo pathway and a transcriptional regulator that controls cell proliferation. We have studied the immunohistochemical expression of YAP in different RMSs, arranged in tissue microarray (TMA) and whole slide formats. Pertinent clinical data including patient age, gender, tumor location, and clinical stage were collected. Out of 96 TMA cases, 30 cases (31%) were pleomorphic, 27 (28%) were embryonal, 24 (25%) alveolar, and 15 (16%) spindle cell. Positive nuclear YAP staining was seen in the PRMS (17/30, 56.7%), SRMS (7/15, 46.7%), ERMS (19/27 or 70%), and less in ARMS (37.5%). YAP nuclear staining was significantly more prevalent in ERMS than ARMS ( p=0.02). Of the 41 whole slide cases, nuclear staining was detected in all ARMS but was restricted in distribution to <30% of the cells, in contrast to ERMS and SRMS, which had diffuse or >30% staining. These results highlight the role of YAP in RMS tumorigenesis, a fact that can be useful in engineering targeted therapy. Restricted nuclear YAP staining (<30% of cells) may be of value in the diagnosis of ARMS. PMID- 29596033 TI - High Prevalence of Ocular Surface Disease Among Glaucoma Patients in Thailand. AB - PURPOSE: To determine the prevalence of symptoms and signs of ocular surface disease (OSD) among Thai patients with glaucoma receiving topical intraocular pressure (IOP)-lowering therapy. METHODS: Consecutive patients with glaucoma were recruited prospectively for this cross-sectional study from Siriraj Hospital. Subjective symptoms were evaluated using the Ocular Surface Disease Index (OSDI), and objective clinical signs were evaluated using the tear breakup time (TBUT), corneal fluorescein, rose bengal staining, and the Schirmer test. RESULTS: One hundred nine patients (56% women; mean age, 64.0 +/- 13.7 years) were included. The mean number of IOP-lowering eye drops instilled daily was 3.2 +/- 2.4; the mean duration of treatment was 5.4 +/- 3.9 years. Forty-two (38.5%) patients reported symptoms using the OSDI. The TBUT was normal in 1 patient, and the others (99.1%) had abnormal tear quality. Fluorescein and rose bengal staining showed positive results in 35 (32.1%) and 42 (38.6%) patients, respectively. The Schirmer test showed decreased tear production in 80 (73.4%) patients. A greater number of IOP-lowering eye drops daily was associated significantly with 3.8 and 4.4 times higher odds of abnormal corneal fluorescein and rose bengal staining, respectively (95% confidence interval [CI], 1.62-9.34, P = 0.002 and 95% CI, 1.91 10.32, P = 0.001, respectively). A significant (P = 0.03, 0.04) correlation was seen between OSDI and corneal dye staining tests. CONCLUSIONS: A high prevalence of OSD was found among glaucoma patients in Thailand. OSD is more prevalent in Asians than in westerners. Awareness regarding prescribing multiple IOP-lowering eye drops in Asians should be heightened to avoid ocular surface toxicity. PMID- 29596032 TI - Occurrence and Characterization of Carbapenemase-Producing Enterobacteriaceae in a Tunisian Hospital. AB - Carbapenem-resistant Enterobacteriaceae have become of particular concern, since they were quickly disseminated in various areas in the world. The aim of the study was to investigate the prevalence of carbapenemase production among clinical isolates of Enterobacteriaceae recovered from the Military Hospital of Tunisia. Bacterial isolates (n = 125) were recovered from patients in diverse services from March 2014 to February 2016 and identified by Vitek II Compact(r). The multiplex PCR for blaVIM, blaIMP, blaNDM, blaKPC, and blaOXA-48 with subsequent amplicon detection by reverse hybridization was performed with the Hyplex SuperBug ID test system (AmplexDiagnostics GmbH, Gars-Bahnhof, Germany). The 125 strains showed resistance to carbapenems of which 102 strains (81.6%) were carbapenemase-producing Enterobacteriaceae and were identified as Klebsiella pneumoniae (85.2%), Enterobacter cloacae (9.8%), Escherichia coli (2.9%), Providencia stuartii (0.9%) and Enterobacter aerogenes (0.9%). These strains were isolated mainly from blood, anal, and urine samples. Patients were mainly hospitalized in the intensive care units, surgery, and medical services. All strains were resistant to ertapenem (100%) and 55.8% showed resistance to imipenem. Carbapenemases genes detected in our study were as follows: blaOXA-48 (84 isolates), blaNDM-1 (8 isolates), blaOXA-48 + blaVIM (5 isolates), and blaOXA 48 + blaNDM-1 (5 isolates). Our research provides epidemiological data showing the quick spread of carbapenem-resistant bacteria in our region, which calls for new surveillance strategies and strict hygiene rules. PMID- 29596034 TI - Postdischarge Correlates of Health Literacy Among Medicaid Inpatients. AB - Health literacy may represent a target for intervention to improve hospital transitions. This study analyzed the association of health literacy with postdischarge utilization among Medicaid patients treated in an integrated health care system. Discharged inpatients covered by Medicaid (N = 112) participated in this observational study set in a single 600-bed hospital in a private, nonprofit, integrated health care system in the southwestern United States. Participants completed surveys within 15 days of discharge, self-reporting demographics, self-care behaviors, and 2 measures of health literacy (REALM-SF [Short Form of the Rapid Estimate of Adult Literacy in Medicine] and Chew [health literacy screen from Chew et al]). Electronic medical records data were incorporated to determine occurrence of 30-day/90-day postdischarge emergency visits and readmission. Half the respondents (54%) scored at the high-school grade equivalent on REALM-SF, while 46% scored adequate health literacy on the Chew. Forty percent (40%) experienced either emergency care or readmission within 90 days post discharge. Patients who were younger, female, or living with children had relatively better health literacy. Health literacy itself was not associated with readmission or postdischarge emergency care, although African American race was. Although Medicaid patients varied considerably on health literacy, this factor was not associated with adverse health care outcomes. Future work should better identify individuals requiring supportive transition services to reduce problems following hospital discharge. PMID- 29596035 TI - Functional status predicts acute care readmission in the traumatic spinal cord injury population. AB - Context/objective Acute care readmission has been identified as an important marker of healthcare quality. Most previous models assessing risk prediction of readmission incorporate variables for medical comorbidity. We hypothesized that functional status is a more robust predictor of readmission in the spinal cord injury population than medical comorbidities. Design Retrospective cross sectional analysis. Setting Inpatient rehabilitation facilities, Uniform Data System for Medical Rehabilitation data from 2002 to 2012 Participants traumatic spinal cord injury patients. Outcome measures A logistic regression model for predicting acute care readmission based on demographic variables and functional status (Functional Model) was compared with models incorporating demographics, functional status, and medical comorbidities (Functional-Plus) or models including demographics and medical comorbidities (Demographic-Comorbidity). The primary outcomes were 3- and 30-day readmission, and the primary measure of model performance was the c-statistic. Results There were a total of 68,395 patients with 1,469 (2.15%) readmitted at 3 days and 7,081 (10.35%) readmitted at 30 days. The c-statistics for the Functional Model were 0.703 and 0.654 for 3 and 30 days. The Functional Model outperformed Demographic-Comorbidity models at 3 days (c statistic difference: 0.066-0.096) and outperformed two of the three Demographic Comorbidity models at 30 days (c-statistic difference: 0.029-0.056). The Functional-Plus models exhibited negligible improvements (0.002-0.010) in model performance compared to the Functional models. Conclusion Readmissions are used as a marker of hospital performance. Function-based readmission models in the spinal cord injury population outperform models incorporating medical comorbidities. Readmission risk models for this population would benefit from the inclusion of functional status. PMID- 29596036 TI - Provider Perspectives on the Collection of Social Determinants of Health. AB - Social determinants of health (SDH) impact health outcomes. Medical centers have begun to collect SDH data, urged by government and scientific entities. Provider perspectives on collecting SDH are unknown. The aim is to understand differences in views and preferences according to provider characteristics. A cross-sectional survey of University of Miami clinical faculty was conducted in late 2016. The survey contained 11 questions: 8 demographic and departmental responsibilities questions and 3 Likert scale questions to capture collection and use of SDH perspectives. The main outcome was whether providers thought the benefit of collecting SDH outweighs the burden and risks. In all, 240 faculty members were included. The majority were men (64%), with a mean age of 51 years. Among participants, 53.5% were non-Hispanic white, 32% were Hispanic, 5% were Black/African American, and 5% were Asian. The majority agreed that SDH are important predictors of health outcomes and quality of care (83%). When comparing minority to nonminority faculty, 25% believed that SDH should only be available to PCPs, compared to 8% of nonminorities (P < 0.01). In a multivariate model, belonging to a racial ethnic minority was the only characteristic associated with believing that benefits of collecting SDH outweigh the risks (odds ratio 1.87, 95% confidence interval 1.02- 3.5) after adjusting for age, sex, minority status, health care provider type, type of responsibilities, and department. This study reveals that although most providers of a health system believe social risks impact health outcomes and quality metrics, the buy-in to collect SDH varies according to the racial/ethnic composition of the faculty. PMID- 29596037 TI - Tissue Engineering Under Microgravity Conditions-Use of Stem Cells and Specialized Cells. AB - Experimental cell research studying three-dimensional (3D) tissues in space and on Earth using new techniques to simulate microgravity is currently a hot topic in Gravitational Biology and Biomedicine. This review will focus on the current knowledge of the use of stem cells and specialized cells for tissue engineering under simulated microgravity conditions. We will report on recent advancements in the ability to construct 3D aggregates from various cell types using devices originally created to prepare for spaceflights such as the random positioning machine (RPM), the clinostat, or the NASA-developed rotating wall vessel (RWV) bioreactor, to engineer various tissues such as preliminary vessels, eye tissue, bone, cartilage, multicellular cancer spheroids, and others from different cells. In addition, stem cells had been investigated under microgravity for the purpose to engineer adipose tissue, cartilage, or bone. Recent publications have discussed different changes of stem cells when exposed to microgravity and the relevant pathways involved in these biological processes. Tissue engineering in microgravity is a new technique to produce organoids, spheroids, or tissues with and without scaffolds. These 3D aggregates can be used for drug testing studies or for coculture models. Multicellular tumor spheroids may be interesting for radiation experiments in the future and to reduce the need for in vivo experiments. Current achievements using cells from patients engineered on the RWV or on the RPM represent an important step in the advancement of techniques that may be applied in translational Regenerative Medicine. PMID- 29596038 TI - Visual Memories Bypass Normalization. AB - How distinct are visual memory representations from visual perception? Although evidence suggests that briefly remembered stimuli are represented within early visual cortices, the degree to which these memory traces resemble true visual representations remains something of a mystery. Here, we tested whether both visual memory and perception succumb to a seemingly ubiquitous neural computation: normalization. Observers were asked to remember the contrast of visual stimuli, which were pitted against each other to promote normalization either in perception or in visual memory. Our results revealed robust normalization between visual representations in perception, yet no signature of normalization occurring between working memory stores-neither between representations in memory nor between memory representations and visual inputs. These results provide unique insight into the nature of visual memory representations, illustrating that visual memory representations follow a different set of computational rules, bypassing normalization, a canonical visual computation. PMID- 29596039 TI - Subclassification of Bethesda Atypical and Follicular Neoplasm Categories According to Nuclear and Architectural Atypia Improves Discrimination of Thyroid Malignancy Risk. AB - BACKGROUND: Although The Bethesda System for Reporting Thyroid Cytopathology has provided clinicians with a standardized classification scheme for the diagnosis of thyroid fine-needle aspiration cytology (FNAC) specimens, the indeterminate categories of Bethesda III (B3)-atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS)-and Bethesda IV (B4)-follicular neoplasm/suspicious for follicular neoplasm (FN/SFN)-continue to pose challenges with regards to ideal diagnostic and therapeutic management. Having previously demonstrated the presence of nuclear atypia as a high-risk subgroup in B3, the objective of this study was to evaluate the malignancy rates in the B4 subgroup with nuclear atypia. METHODS: A retrospective review of all thyroid FNACs diagnosed as B4 (FN/SFN) between 2008 and 2015 was conducted at a tertiary referral center in Singapore. Data on patient demographics, sonographic features, and final histological diagnosis were collected. This was compared to data from a previous analysis on all nodules diagnosed as B3 (AUS/FLUS) over a similar period. RESULTS: A total of 137/309 (44.3%) and 88/111 (79.3%) FNACs diagnosed as B3 and B4, respectively, underwent surgical excision yielding final histopathological diagnoses. The malignancy rate of B4 was 31/88 (35.2%) compared to B3, which was 37/137 (27.0%). Subclassification based on the presence of architectural versus nuclear atypia showed significantly higher malignancy rates in B4 nodules with nuclear atypia (21.8% vs. 57.6%; p < 0.01). These findings corroborate previous results within the B3 category (malignancy rate of 14.7% vs. 36.8%; p < 0.01). The only sonographic features predictive of malignancy were the presence of macrocalcifications in B4 compared to irregularity of margins in B3. CONCLUSION: The presence of nuclear atypia identifies subgroups with significant differential malignancy risks within both the B3 and B4 categories. This supports the notion that subclassification is a useful risk stratification tool that can guide diagnostic and therapeutic management of indeterminate thyroid nodules with heterogenous risk profiles. PMID- 29596040 TI - Comparative Study of Drainage and Antibiotics versus Drainage Only in the Management of Primary Subcutaneous Abscesses. AB - BACKGROUND: Skin and soft tissue infections are common problems dealt with in emergency departments and medical offices. It is routine practice to prescribe antibiotic agents after incision and drainage of cutaneous abscesses. However, current evidence does not support prescribing oral antibiotic agents after surgical debridement. The aim of the present study was to determine the actual role of antibiotic agents after drainage of cutaneous abscesses. PATIENTS AND METHODS: This was a prospective study of patients undergoing incision and drainage (I&D) of a subcutaneous abscess. Patients were randomly assigned either to receive antibiotic agents (group 1) or placebo (group 2) after I&D. The primary end point was resolution rate of the abscess at the seventh day. Secondary end points were pain at the seventh day and total time to full healing of the wound. P value <0.05 was considered statistically significant. RESULTS: One hundred sixty-five patients were included for analysis. Age, gender, body mass index (BMI), and comorbidities did not differ substantially between groups. Chest and peri-anal abscesses were statistically more frequent in group 2, whereas neck abscesses were more frequent in group 1 (p = 0.02). Leukocyte count was also statistically higher in group 1 (p = 0.005). Resolution rate was 96% in group 1 and 93% in group 2, with no statistical difference between both (p = 0.28). Neither pain at seventh day nor time to full healing differed statistically between groups. CONCLUSIONS: Antibiotic agents are not necessary for uncomplicated subcutaneous abscesses after I&D. These cases can be managed safely on an outpatient basis without any increase in morbidity. PMID- 29596041 TI - Implementing Outcome Measures in Palliative Care. PMID- 29596042 TI - Ten Tips Nephrologists Wish the Palliative Care Team Knew About Caring for Patients with Kidney Disease. AB - Many patients with chronic kidney disease (CKD) and end-stage renal disease have unmet palliative care (PC) needs. Physical and emotional symptoms are common. Some, like uremia and fluid overload, improve with dialysis, but the increasing age of patients initiating renal replacement therapy leaves many untreatable comorbidities like dementia and frailty to negatively impact quality of life. Written by nephrologists and PC clinicians, this article will help PC providers to have a richer understanding of kidney disease-related symptom burden, disease trajectory, prognosis, and barriers to hospice enrollment for patients with CKD and end-stage renal disease. PMID- 29596043 TI - Sex-Specific Associations Between Complement Component 3 and Component 4 Levels and Metabolic Syndrome in an Adult Population. AB - BACKGROUND: Metabolic syndrome (MetS) is a cluster of cardiovascular and metabolic risk factors in the same individual. Inflammation has been reported to be directly involved in the development of metabolic disease. Complement component 3 (C3) and complement component 4 (C4) have been identified as important inflammatory markers relevant to metabolic disease. However, few studies have analyzed the association between C3 and/or C4 and MetS. In this study, our aim is to evaluate sex-specific association between C3 and C4 levels and risk of MetS in an adult population. METHODS: A cohort of 4635 adults was followed from 2010 to 2016. Serum C3 and C4 levels were measured using an immunonephelometric technique. MetS was defined by the American Heart Association scientific statements of 2009. Cox proportional hazard regression models were used to assess sex-specific association between C3 and C4 levels and the incidence of MetS. RESULTS: During the ~6 years of follow-up, 1445 new cases of MetS were identified. After being adjusted to confounding factors, the hazard ratios (95% confidence interval) of MetS for gradually increasing quintiles of C3 were 1.00, 1.23 (0.98-1.54), 1.50 (1.21-1.87), 1.64 (1.32-2.04), and 1.75 (1.41 2.18) (P for trend <0.0001) in men and 1.00, 0.96 (0.60-1.53), 1.61 (1.06-2.44), 2.01 (1.34-3.03), and 2.43 (1.63-3.63) (P for trend <0.0001) in women, respectively. Similar results were also obtained for gradually increasing quintiles of C4 in women, but not in men. CONCLUSIONS: The levels of C3 were significantly associated with the incidence of MetS in both men and women. The levels of C4 contributed to risk of MetS only in women. PMID- 29596044 TI - The Effects of High-Protein and High-Monounsaturated Fat Meals on Postprandial Lipids, Lipoprotein Particle Numbers, Cytokines, and Leptin Responses in Overweight/Obese Subjects. AB - BACKGROUND: Obesity is linked to dyslipidemia, proinflammatory state, and hyperleptinemia. The influence of high-protein (HP) versus high-monounsaturated fat (HMF) meals on postprandial lipids, lipoprotein particle numbers, cytokines, and leptin responses in overweight/obese (OW/O) subjects is unknown. METHODS: Twenty-four OW/O participants consumed an HP (31.9% energy from protein) and HMF (35.2% fat and 20.7% monounsaturated fat) meal, of similar energy/carbohydrate content, in a random order. The outcome variables were assessed from blood samples collected in fasted and postprandial (3 hr) states. RESULTS: Repeated measures analysis found significant (P < 0.05) meal condition by time interactions for triglycerides (TGs), very low-density lipoprotein particles (VLDLP), total high-density lipoprotein particles (T-HDLP), and the ratio of large-buoyant high-density lipoprotein 2b (LB-HDL2b) to T-HDLP, and meal effect on small-dense HDLP (SD-HDLP). Comparison of HP versus HMF condition showed significantly lower TG at 120 min [geometric mean (95% confidence interval, CI): 148 (125-175) vs. 194 (164-230) mg/dL] and 180 min [167 (138-203) vs. 230 (189 278) mg/dL] and VLDLP at 180 min [70.0 (58.2-84.3) vs. 88.0 (73.1-106) nmol/L]. HP versus HMF condition showed significantly lower LB-HDL2b/T-HDLP at 180 min [mean difference (95% CI): 0.021 (0.004-0.038)], and higher T-HDLP [671 (263 1079) nmol/L] and SD-HDLP [606 (292-920) nmol/L] at 120 min. Area under the curve was significantly lower for TG and higher for T-HDLP, SD-HDLP, and small-dense LDL III (SD-LDL III) in the HP condition. Cytokines and leptin were not different between conditions. CONCLUSION: OW/O subjects had lower TG and VLDLP, but less favorable SD-LDL III, SD-HDLP, and LB-HDL2b/T-HDLP ratio responses to the HP versus HMF meals. PMID- 29596045 TI - Positive behaviour support training for staff for treating challenging behaviour in people with intellectual disabilities: a cluster RCT. AB - BACKGROUND: Preliminary studies have indicated that training staff in Positive Behaviour Support (PBS) may help to reduce challenging behaviour among people with intellectual disability (ID). OBJECTIVE: To evaluate whether or not such training is clinically effective in reducing challenging behaviour in routine care. The study also included longer-term follow-up (approximately 36 months). DESIGN: A multicentre, single-blind, two-arm, parallel-cluster randomised controlled trial. The unit of randomisation was the community ID service using an independent web-based randomisation system and random permuted blocks on a 1 : 1 allocation stratified by a staff-to-patient ratio for each cluster. SETTING: Community ID services in England. PARTICIPANTS: Adults (aged > 18 years) across the range of ID with challenging behaviour [>= 15 Aberrant Behaviour Checklist - Community total score (ABC-CT)]. INTERVENTIONS: Manual-assisted face-to-face PBS training to therapists and treatment as usual (TAU) compared with TAU only in the control arm. MAIN OUTCOME MEASURES: Carer-reported changes in challenging behaviour as measured by the ABC-CT over 12 months. Secondary outcomes included psychopathology, community participation, family and paid carer burden, family carer psychopathology, costs of care and quality-adjusted life-years (QALYs). Data on main outcome, service use and health-related quality of life were collected for the 36-month follow-up. RESULTS: A total of 246 participants were recruited from 23 teams, of whom 109 were in the intervention arm (11 teams) and 137 were in the control arm (12 teams). The difference in ABC-CT between the intervention and control arms [mean difference -2.14, 95% confidence interval (CI) -8.79 to 4.51; p = 0.528] was not statistically significant. No treatment effects were found for any of the secondary outcomes. The mean cost per participant in the intervention arm was L1201. Over 12 months, there was a difference in QALYs of 0.076 in favour of the intervention (95% CI 0.011 to 0.140 QALYs) and a 60% chance that the intervention is cost-effective compared with TAU from a health and social care cost perspective at the threshold of L20,000 per QALY gained. Twenty-nine participants experienced 45 serious adverse events (intervention arm, n = 19; control arm, n = 26). PBS plans were available for 33 participants. An independent assessment of the quality of these plans found that all were less than optimal. Forty-six qualitative interviews were conducted with service users, family carers, paid carers and service managers as part of the process evaluation. Service users reported that they had learned to manage difficult situations and had gained new skills, and carers reported a positive relationship with therapists. At 36 months' follow-up (n = 184), the mean ABC-CT difference between arms was not significant (-3.70, 95% CI -9.25 to 1.85; p = 0.191). The initial cost-effectiveness of the intervention dissipated over time. LIMITATIONS: The main limitations were low treatment fidelity and reach of the intervention. CONCLUSIONS: Findings from the main study and the naturalistic follow-up suggest that staff training in PBS as delivered in this study is insufficient to achieve significant clinical gains beyond TAU in community ID services. Although there is an indication that training in PBS is potentially cost-effective, this is not maintained in the longer term. There is increased scope to develop new approaches to challenging behaviour as well as optimising the delivery of PBS in routine clinical practice.

PMID- 29596048 TI - Intimate Partner Violence and Uptake of Antenatal Care: A Scoping Review of Low- and Middle-Income Country Studies. AB - CONTEXT: Intimate partner violence (IPV) is associated with negative physical and mental health outcomes. Antenatal care can act as a link to IPV services, but experiencing IPV may be associated with reduced uptake of antenatal care, an issue that has received little attention from researchers. METHODS: A scoping review was conducted to synthesize quantitative research on IPV and uptake of antenatal care in low-resource settings. Keyword searches of PubMed and other databases and snowball searches of reference lists were conducted to identify articles published in 2005-2015 that measured one or more types of IPV (physical, sexual or emotional) or controlling behavior and assessed the relationship of such abuse with use of antenatal care. For each identified article, key characteristics and findings were abstracted, and study quality was assessed. RESULTS: Sixteen articles, representing 10 low- and middle-income countries, met the inclusion criteria. Most studies were of medium-to-high quality but low rigor, reflecting the abundance of cross-sectional studies in the literature. In all 16 studies, IPV was negatively associated with initiation of antenatal care, number of visits or use of a skilled provider. Analyses revealed reduced odds of antenatal care use among women who had experienced IPV (odds ratios, 0.5-0.8) and elevated odds of antenatal care use among women who had not experienced IPV or of nonuse among women who had experienced IPV (1.2-4.1). CONCLUSION: Women in low resource settings who experience IPV have a reduced likelihood of obtaining optimal antenatal care and may benefit from interventions to mitigate barriers to care.

PMID- 29596046 TI - Ensemble cryoEM elucidates the mechanism of insulin capture and degradation by human insulin degrading enzyme. AB - Insulin degrading enzyme (IDE) plays key roles in degrading peptides vital in type two diabetes, Alzheimer's, inflammation, and other human diseases. However, the process through which IDE recognizes peptides that tend to form amyloid fibrils remained unsolved. We used cryoEM to understand both the apo- and insulin bound dimeric IDE states, revealing that IDE displays a large opening between the homologous ~55 kDa N- and C-terminal halves to allow selective substrate capture based on size and charge complementarity. We also used cryoEM, X-ray crystallography, SAXS, and HDX-MS to elucidate the molecular basis of how amyloidogenic peptides stabilize the disordered IDE catalytic cleft, thereby inducing selective degradation by substrate-assisted catalysis. Furthermore, our insulin-bound IDE structures explain how IDE processively degrades insulin by stochastically cutting either chain without breaking disulfide bonds. Together, our studies provide a mechanism for how IDE selectively degrades amyloidogenic peptides and offers structural insights for developing IDE-based therapies. PMID- 29596047 TI - Oligodendrocytes control potassium accumulation in white matter and seizure susceptibility. AB - The inwardly rectifying K+ channel Kir4.1 is broadly expressed by CNS glia and deficits in Kir4.1 lead to seizures and myelin vacuolization. However, the role of oligodendrocyte Kir4.1 channels in controlling myelination and K+ clearance in white matter has not been defined. Here, we show that selective deletion of Kir4.1 from oligodendrocyte progenitors (OPCs) or mature oligodendrocytes did not impair their development or disrupt the structure of myelin. However, mice lacking oligodendrocyte Kir4.1 channels exhibited profound functional impairments, including slower clearance of extracellular K+ and delayed recovery of axons from repetitive stimulation in white matter, as well as spontaneous seizures, a lower seizure threshold, and activity-dependent motor deficits. These results indicate that Kir4.1 channels in oligodendrocytes play an important role in extracellular K+ homeostasis in white matter, and that selective loss of this channel from oligodendrocytes is sufficient to impair K+ clearance and promote seizures. PMID- 29596050 TI - Testing for HbA1c, in addition to the oral glucose tolerance test, in screening for abnormal glucose regulation helps to reveal patients with early beta-cell function impairment. AB - BACKGROUND: The oral glucose tolerance test (OGTT) is recommended to screen for diabetes in patients with coronary artery disease. We hypothesized that testing for glycated hemoglobin (HbA1c), in addition to the OGTT, in screening for abnormal glucose regulation may help to reveal patients with beta-cell function impairment. METHODS: Patients with no history of diabetes who were admitted for coronary angiography were recruited to undergo an OGTT and HbA1c test 2-4 weeks after hospital discharge. beta-cell function and insulin resistance were assessed using the homeostasis model assessment (HOMA-beta and HOMA-IR, respectively). For patients with normal glucose tolerance (NGT) based on the OGTT, we compared HOMA beta between two subgroups of patients using an HbA1c cutoff of 39 mmol/mol or 42 mmol/mol. For patients with prediabetes based on an OGTT, we compared the HOMA beta between two subgroups of patients using an HbA1c cutoff of 48 mmol/mol. RESULTS: A total of 1044 patients were analyzed. In patients with NGT by OGTT (n=432), those with an HbA1c >=42 mmol/mol had a lower HOMA-beta compared to those with an HbA1c <42 mmol/mol (107+/-82 vs. 132+/-96, p=0.018). In patients with prediabetes by OGTT (n=423), those with an HbA1c >=48 mmol/mol had a lower HOMA-beta compared to those with an HbA1c <48 mmol/mol (91+/-52 vs. 120+/-88, p=0.003). No significant between-group difference in HOMA-IR was noted. CONCLUSIONS: The use of HbA1c in addition to the OGTT in screening for abnormal glucose regulation helped to reveal patients with early beta-cell function impairment.

PMID- 29596052 TI - The impact of mild hypercholesterolemia on glycemic and hormonal profiles, menstrual characteristics and the ovarian morphology of women with polycystic ovarian syndrome. AB - Background The severity of polycystic ovarian syndrome (PCOS) has been clearly associated with insulin resistance, obesity and metabolic syndrome. The purpose of the present cross-sectional study is to investigate whether mild hypercholesterolemia alters the biochemical and clinical profile of PCOS patients. Methods Our study is based on a prospectively collected population of women of reproductive age who were diagnosed with PCOS according to the definition of the Rotterdam European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine (ASRM/ESHRE) criteria. For the correlation analysis we used the non-parametric Spearman's rank correlation coefficient. Partial correlation was also performed to control for potential confounders observed in the univariate analysis. Results Overall, 235 patients were included. Their mean age ranged between 14 and 45 years old and the body mass index (BMI) between 17 and 54. Women with mild hypercholesterolemia had a higher BMI and their fasting insulin was increased as well as indices of insulin resistance [Homeostatic model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), Matsuda index] compared to women with PCOS with normal cholesterol levels. Correlation statistics suggested that the effect of serum lipids on the hormonal profile of patients was weak. Both low-density lipoprotein (LDL) and high-density lipoprotein (HDL) exerted a significant mild negative correlation to glucose and insulin. However, after controlling the results for BMI and age (the two variables that were found significantly different in the univariate analysis) we observed that this effect was non-significant. Conclusion Mild hypercholesterolemia does not affect the hormonal profile of patients with PCOS; hence, to date, there is no evidence to suggest its treatment for the correction of menstrual and hormonal abnormalities in PCOS women.

PMID- 29596053 TI - The "adipose tissue expandability" hypothesis: a potential mechanism for insulin resistance in obese youth. AB - Obesity has become a major global health challenge of the 21st century, as it is associated with the onset of type 2 diabetes (T2D) and cardiovascular complications, even at a very early age in life. The root causes of pediatric obesity remain incompletely understood. The obesity epidemic together with the relationship of obesity to the growing population burden of chronic disease presents unprecedented research opportunities and challenges. Decades of obesity related research funded by governments around the world have yielded many important discoveries about both etiological pathways and preventive or therapeutic interventions. Yet, there is a sense that the problem is outpacing these research efforts. Obesity poses a significant risk for the development of cardiovascular disease (CVD) , diabetes and certain cancers thereby shortening life expectancy. Nevertheless, many obese individuals do not develop any of these comorbidities. One hypothesis explaining this dilemma is that total body fat is not the culprit of adverse health in obesity rather the relative proportion of lipids in various fat depots is what determines the metabolic risk. In this review, we describe the role of altered fat partitioning in youth onset obesity and its relation to fatty liver and T2D during adolescence.

AB - This work presents investigations of biologically active metabolites of Usnea barbata lichen. Extraction conditions for usnic acid and other biologically active phytocomponents using various solvent systems were chosen.

PMID- 29596057 TI - Light controllable catalytic activity of Au clusters decorated with photochromic molecules. AB - By ab initio calculations, we show that when decorated with a photochromic molecule, the catalytic activity of an Au nanocluster can be reversibly controlled by light. The combination of a photochromic thiol-pentacarbonyl azobenzene (TPA) molecule and an Au8 cluster is chosen as a model catalyst. The TPA molecule has two configurations (trans and cis) that can be reversibly converted to each other upon photo-excitation. Our calculations show that when the TPA takes the trans configuration, the combined system (trans-Au8) is an excellent catalyst for CO oxidation. The reaction barrier of the catalyzed CO oxidation is less than 0.4 eV. While, the reaction barrier of CO oxidation catalyzed by cis-Au8 is very high (>2.7 eV), indicating that the catalyst is inactive. These results pave the way for a new class of light controllable nanoscale catalysts. PMID- 29596058 TI - Manipulating the assembly of perovskites onto soft nanoimprinted titanium dioxide templates. AB - Soft nanoimprinted titanium dioxide (TiO2) substrates decorated with methylammonium lead halide perovskite (MAPbI3) crystals were fabricated by controlling the perovskite precursor concentration and volume during spin coat processing combined with the use of hydrophobic TiO2 templates. The patterned growth was demonstrated with different perovskite crystallization methods. We investigated and successfully demonstrated the controlled assembly of two MAPbI3 nanomaterials, one a nanocomposite formed between the perovskite and a hole conducting polymer poly(2,5-bis(N-methyl-N-hexylamino)phenylene vinylene) (BAMPPV), and a second formed from perovskite crystals using common solution based MAPbI3 growth methods (1-step and 2-step processing). Both types of MAPbI3 crystals were fabricated on hydrophobic TiO2 nanotemplates composed of nanowells or grating patterns. Patterned areas as large as 100 MUm * 100 MUm were achieved. We examined and characterized the substrates using atomic force microscopy, scanning electron microscopy, x-ray diffraction, and energy dispersive spectroscopy. We present the optical properties (i.e. fluorescence and transmission) of soft nanoimprinted nanowells decorated with perovskites demonstrating the successful synthesis of MAPbI3 perovskite nanocrystals. As an example of their use, we demonstrate a two terminal device and show photocurrent response of a perovskite patterned micro-grating. Our method is a nondestructive approach to nanopatterning perovskites, and produces patterned arrays that maintain their photo-electric properties. The results presented herein suggests an attractive route to developing nanopatterned and small area perovskite substrates for applications in photovoltaics, x-ray sensing/detection, image sensor arrays, and others. PMID- 29596059 TI - A brain-age model for preterm infants based on functional connectivity. AB - OBJECTIVE: In this study, the development of EEG functional connectivity during early development has been investigated in order to provide a predictive age model for premature infants. APPROACH: The functional connectivity has been assessed via the coherency function (its imaginary part (ImCoh) and its mean squared magnitude (MSC)), the phase locking value ([Formula: see text]) and the Hilbert-Schimdt dependence (HSD) in a dataset of 30 patients, partially described and employed in previous studies (Koolen et al 2016 Neuroscience 322 298-307; Lavanga et al 2017 Complexity 2017 1-13). Infants' post-menstrual age (PMA) ranges from 27 to 42 weeks. The topology of the EEG couplings has been investigated via graph-theory indices. MAIN RESULTS: Results show a sharp decrease in ImCoh indices in theta, (4-8) Hz and alpha, (8-16) Hz bands and MSC in beta, (16-32) Hz band with maturation, while a more modest positive correlation with PMA is found for HSD, [Formula: see text] and MSC in [Formula: see text], theta, alpha bands. The best performances for the PMA prediction were mean absolute error equal to 1.51 weeks and adjusted coefficient of determination [Formula: see text] equal to 0.8. SIGNIFICANCE: The reported findings suggest a segregation of the cortex connectivity, which favours a diffused tasks architecture on the brain scalp. In summary, the results indicate that the neonates' brain development can be described via lagged-interaction network features. PMID- 29596060 TI - Antibacterial activity and inflammation inhibition of ZnO nanoparticles embedded TiO2 nanotubes. AB - Titanium (Ti) with nanoscale structure on the surface exhibits excellent biocompatibility and bone integration. Once implanted, the surgical implantation may lead to bacterial infection and inflammatory reaction, which cause the implant failure. In this work, irregular and nanorod-shaped ZnO nanoparticles were doped into TiO2 nanotubes (TNTs) with inner diameter of about 50 nm by electro-deposition. The antibacterial properties of ZnO incorporated into TiO2 nanotubes (TNTs/ZnO) were evaluated using Staphylococcus aureus (S. aureus). Zn ions released from the nanoparticles and the morphology could work together, improving antibacterial effectiveness up to 99.3% compared with the TNTs. Macrophages were cultured on the samples to determine their respective anti inflammatory properties. The proliferation and viability of macrophages were evaluated by the CCK-8 method and Live&Dead stain, and the morphology of the cells was observed by scanning electron microscopy. Results indicated that TNTs/ZnO has a significant inhibitory effect on the proliferation and adhesion of macrophages, which could be used to prevent chronic inflammation and control the inflammatory reaction. Besides, the release of Zn ions from the ZnO nanoparticles is a long-term process, which could be beneficial for bone integration. Results demonstrate that ZnO deposited into TNTs improved the antibacterial effectiveness and weakened the inflammatory reaction of titanium-based implants, which is a promising approach to enhance their bioactivity. PMID- 29596061 TI - Effect of magnetization boundary condition on cavity magnon polariton of YIG thin film. AB - Motivated by recent studies of cavity magnon polariton (CMP), we extended a previous theoretical work to generalize microwave transmission calculation with various magnetization boundary condition of YIG thin film embedded in cavity. It is found that numerical implementation given in this paper can be easily applied to other magnetization boundary condition and extended to magnetic multilayers. Numerical results show that ferromagnetic resonance mode of microwave transmission spectrum, which is absent in previous calculation, can be recovered by altering the pinning condition of surface spins. The demonstrated reliability of our theory opens attractive perspectives for studying CMP of thin film with complicated surface magnetization distribution and magnetic multilayers. PMID- 29596062 TI - Imaging activated T cells predicts response to cancer vaccines. AB - In situ cancer vaccines are under active clinical investigation, given their reported ability to eradicate both local and disseminated malignancies. Intratumoral vaccine administration is thought to activate a T cell-mediated immune response, which begins in the treated tumor and cascades systemically. In this study, we describe a PET tracer (64Cu-DOTA-AbOX40) that enabled noninvasive and longitudinal imaging of OX40, a cell-surface marker of T cell activation. We report the spatiotemporal dynamics of T cell activation following in situ vaccination with CpG oligodeoxynucleotide in a dual tumor-bearing mouse model. We demonstrate that OX40 imaging was able to predict tumor responses on day 9 after treatment on the basis of tumor tracer uptake on day 2, with greater accuracy than both anatomical and blood-based measurements. These studies provide key insights into global T cell activation following local CpG treatment and indicate that 64Cu-DOTA-AbOX40 is a promising candidate for monitoring clinical cancer immunotherapy strategies.

PMID- 29596063 TI - Neuronal hypothalamic regulation of body metabolism and bone density is galanin dependent. AB - In the brain, the ventral hypothalamus (VHT) regulates energy and bone metabolism. Whether this regulation uses the same or different neuronal circuits is unknown. Alteration of AP1 signaling in the VHT increases energy expenditure, glucose utilization, and bone density, yet the specific neurons responsible for each or all of these phenotypes are not identified. Using neuron-specific, genetically targeted AP1 alterations as a tool in adult mice, we found that agouti-related peptide-expressing (AgRP-expressing) or proopiomelanocortin expressing (POMC-expressing) neurons, predominantly present in the arcuate nucleus (ARC) within the VHT, stimulate whole-body energy expenditure, glucose utilization, and bone formation and density, although their effects on bone resorption differed. In contrast, AP1 alterations in steroidogenic factor 1 expressing (SF1-expressing) neurons, present in the ventromedial hypothalamus (VMH), increase energy but decrease bone density, suggesting that these effects are independent. Altered AP1 signaling also increased the level of the neuromediator galanin in the hypothalamus. Global galanin deletion (VHT galanin silencing using shRNA) or pharmacological galanin receptor blockade counteracted the observed effects on energy and bone. Thus, AP1 antagonism reveals that AgRP- and POMC-expressing neurons can stimulate body metabolism and increase bone density, with galanin acting as a central downstream effector. The results obtained with SF1-expressing neurons, however, indicate that bone homeostasis is not always dictated by the global energy status, and vice versa. PMID- 29596064 TI - Contributions of inflammation and tumor microenvironment to neurofibroma tumorigenesis. AB - Neurofibromatosis type 1 associates with multiple neoplasms, and the Schwann cell tumor neurofibroma is the most prevalent. A hallmark feature of neurofibroma is mast cell infiltration, which is recruited by chemoattractant stem cell factor (SCF) and has been suggested to sustain neurofibroma tumorigenesis. In the present study, we use new, genetically engineered Scf mice to decipher the contributions of tumor-derived SCF and mast cells to neurofibroma development. We demonstrate that mast cell infiltration is dependent on SCF from tumor Schwann cells. However, removal of mast cells by depleting the main SCF source only slightly affects neurofibroma progression. Other inflammation signatures show that all neurofibromas are associated with high levels of macrophages regardless of Scf status. These findings suggest an active inflammation in neurofibromas and partly explain why mast cell removal alone is not sufficient to relieve tumor burden in this experimental neurofibroma model. Furthermore, we show that plexiform neurofibromas are highly associated with injury-prone spinal nerves that are close to flexible vertebras. In summary, our study details the role of inflammation in neurofibromagenesis. Our data indicate that prevention of inflammation and possibly also nerve injury at the observed tumor locations are therapeutic approaches for neurofibroma prophylaxis and that such treatment should be explored. PMID- 29596066 TI - Sudden Unexpected Death in Epilepsy: Incidence, Risk Factors, and Proposed Mechanisms. AB - Epilepsy is a common neurological disorder associated with increased morbidity and mortality, including premature death from different causes. Sudden unexpected death in epilepsy, or SUDEP, is one of the most common causes of death in people with epilepsy and originally brought to light by medical examiners. It accounts for 5% to 30% of all deaths in individuals with epilepsy and up to 50% in individuals with medically refractory epilepsy. It is commonly associated with a history of generalized tonic-clonic seizures and may be mitigated by other electroclinical risk factors, such as postictal electroencephalographic suppression, prone position, altered heart rate variability, conduction abnormalities, gender, or antiepileptic medications, to name a few. More recently, potential neuroimaging biomarkers have also been identified. Still, despite the increased mortality risk in people with epilepsy due to SUDEP, little is known about its underlying pathophysiology. The pathogenesis is likely to be multifactorial, resulting in neurogenic pulmonary edema or, in some cases, fatal cardiac arrhythmias. Medical examiners can provide an important role in our understanding of the magnitude of the problem and ongoing research into the underlying mechanisms. In this review, we discuss diagnostic criteria, incidence, risk factors, and current theories regarding the pathophysiology of SUDEP.

AB - As digital innovations continue to transform health systems in Canada, it is important to examine registered nurses' preparedness in informatics, and factors associated with informatics competency. An exploratory, descriptive, cross sectional survey was used to determine self-perceived informatics competencies, and factors associated with competency, among practicing nurses in Alberta. Results from 2844 completed surveys showed that nurses' self-perceived informatics competency was slightly above the mark of competent. Perceptions of competency were highest on foundational computer literacy skills and lowest on information and knowledge management competencies. However, overall informatics competency mean scores varied significantly in relation to age, educational qualification, years of experience, and work setting. The quality of informatics training and support offered by employers contributed the most to variance in mean scores of total and subdomains of informatics competency. Other factors, such as age, educational qualification, work setting, previous informatics education, access to the Internet, use of health technology, access to supporting resources, informatics training, an informatics role, and continuing education in informatics, also contributed to mean scores variance in differing degrees. Findings from this study provide a basis for actionable policies to address informatics educational needs and support requirements among nurses practicing now and in the future. PMID- 29596069 TI - Validation of the Microlife WatchBP Home blood pressure device in pregnancy for medium and large arm circumferences. AB - OBJECTIVE: The Microlife WatchBP Home automated blood pressure device was assessed for accuracy in pregnant women of medium (<32 cm) and large (>=32 cm) arm circumference. MATERIALS AND METHODS: The British Hypertension Society validation protocol was modified for the purpose of this study to include women with arm circumference of less than 32 cm (N=51) and greater than or equal to 32 cm (N=46) as two separate arms. RESULTS: The device achieved an overall A/A grade for medium arm circumference and B/A grade for large arm circumference. The mean+/-SD device-observer difference was 1.7+/-6.2 and -0.4+/-4.4 for systolic and diastolic blood pressure, respectively, for medium arm circumference and 3.0+/-8.5 and 1.5+/-5.1, respectively, for large arm circumference. When all women with pre-eclampsia from both groups were pooled (N=23), the device achieved an overall grade of A/A with mean differences of 2.1+/-7.2 for systolic blood pressure and 1.0+/-5.6 for diastolic blood pressure. CONCLUSION: The Microlife WatchBP Home automated blood pressure device can be recommended for use in pregnant women of all gestations, including those with pre-eclampsia. However, caution is needed for women with large arm circumferences. PMID- 29596070 TI - Chronic Myelomonocytic Leukemia With Fibrosis Is a Distinct Disease Subset With Myeloproliferative Features and Frequent JAK2 p.V617F Mutations. AB - A subset of patients with chronic myelomonocytic leukemia (CMML) presents with significance myelofibrosis. In myelodysplastic syndromes, significant myelofibrosis has been associated with adverse outcomes and p53 dysregulation. However, in CMML the clinical and molecular correlates of significant myelofibrosis at presentation remain poorly understood. From a cohort of 651 CMML patients, we identified retrospectively 20 (3.1%) cases with moderate to severe reticulin fibrosis (CMML-F) detected at diagnosis, and we compared them to CMML patients without fibrosis (n=631) seen during the same period. Patients with CMML F had a median age of 69.8 years (range, 24.8 to 91.2 y) and most (13; 65%) were men. Patients with CMML-F differed significantly from other CMML patients across the following parameters: white blood count, absolute monocyte count, serum lactate dehydrogenase level, splenomegaly, and bone marrow blast percentage. Notably, the frequency of JAK2 p.V617F mutation was higher in CMML-F patients compared with other CMML patients (P<0.001). Most CMML-F patients (12/20; 60%) had myeloproliferative CMML. Dysregulation of p53 was uncommon in CMML-F. CMML-F patients tended to have a shorter median overall survival compared with other CMML patients (P=0.079). Multivariate analysis using the Cox proportional hazards model showed an independent association between CMML-F and overall survival (P=0.047). In summary, unlike typical CMML, CMML-F is commonly associated with JAK2 p.V617F. The high frequency of myeloproliferative features and JAK2 p.V617F mutation, and the low frequency of p53 dysregulation, suggest that fibrosis in the context of CMML has a different pathogenesis from that previously reported in myelodysplastic syndrome. PMID- 29596071 TI - An Observational Cohort Study Examining the Effect of the Duration of Skin-to Skin Contact on the Physiological Parameters of the Neonate in a Neonatal Intensive Special Care Unit. AB - BACKGROUND: Focus on skin-to-skin contact (SSC) as a family-centered care intervention in Neonatal Intensive Special Care (NISC) Units continues to increase. Previously, SSC has been shown to improve neonatal physiological stability, support brain development, and promote bonding and attachment. Limited research exists investigating SSC duration and neonatal physiological responses. PURPOSE: This study examined the relationship between SSC duration and the neonate's oxygen saturation, heart rate (HR), respiratory rate (RR), and temperature. METHOD: An observational cohort study was conducted at The Royal Women's Hospital NISC Unit in Melbourne, Australia. For each neonate participant, 1 SSC with their parent was studied (parent convenience) and neonatal physiological parameters recorded, with a bivariate correlation used to explore the relationship between the duration of SSC and the percentage of time during SSC that the neonate's physiological variables remained within a target range. FINDINGS: No correlation existed between the duration of SSC and the neonatal physiological variables of oxygen saturation, HR, RR, and temperature. However, neonatal oxygen requirement was more often reduced across the duration of SSC. IMPLICATIONS FOR PRACTICE AND FUTURE RESEARCH: Due to previously documented benefits to neonates physiologically from SSC, and our supportive finding that SSC reduces neonatal oxygen requirement, we believe that this study adds to the evidence to support promotion of SSC in NISC Units. The duration of SSC does not appear to negatively impact the physiological effects to the neonate. Thus, SSC should be encouraged in all NISC Units to be conducted for the length of time the parent is able. This study should be repeated with a larger sample size. PMID- 29596072 TI - The Speaker Gender Gap at Critical Care Conferences. AB - OBJECTIVES: To review women's participation as faculty at five critical care conferences over 7 years. DESIGN: Retrospective analysis of five scientific programs to identify the proportion of females and each speaker's profession based on conference conveners, program documents, or internet research. SETTING: Three international (European Society of Intensive Care Medicine, International Symposium on Intensive Care and Emergency Medicine, Society of Critical Care Medicine) and two national (Critical Care Canada Forum, U.K. Intensive Care Society State of the Art Meeting) annual critical care conferences held between 2010 and 2016. SUBJECTS: Female faculty speakers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Male speakers outnumbered female speakers at all five conferences, in all 7 years. Overall, women represented 5-31% of speakers, and female physicians represented 5-26% of speakers. Nursing and allied health professional faculty represented 0-25% of speakers; in general, more than 50% of allied health professionals were women. Over the 7 years, Society of Critical Care Medicine had the highest representation of female (27% overall) and nursing/allied health professional (16-25%) speakers; notably, male physicians substantially outnumbered female physicians in all years (62-70% vs 10-19%, respectively). Women's representation on conference program committees ranged from 0% to 40%, with Society of Critical Care Medicine having the highest representation of women (26-40%). The female proportions of speakers, physician speakers, and program committee members increased significantly over time at the Society of Critical Care Medicine and U.K. Intensive Care Society State of the Art Meeting conferences (p < 0.05), but there was no temporal change at the other three conferences. CONCLUSIONS: There is a speaker gender gap at critical care conferences, with male faculty outnumbering female faculty. This gap is more marked among physician speakers than those speakers representing nursing and allied health professionals. Several organizational strategies can address this gender gap. PMID- 29596073 TI - The Development of a Machine Learning Inpatient Acute Kidney Injury Prediction Model. AB - OBJECTIVES: To develop an acute kidney injury risk prediction model using electronic health record data for longitudinal use in hospitalized patients. DESIGN: Observational cohort study. SETTING: Tertiary, urban, academic medical center from November 2008 to January 2016. PATIENTS: All adult inpatients without pre-existing renal failure at admission, defined as first serum creatinine greater than or equal to 3.0 mg/dL, International Classification of Diseases, 9th Edition, code for chronic kidney disease stage 4 or higher or having received renal replacement therapy within 48 hours of first serum creatinine measurement. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Demographics, vital signs, diagnostics, and interventions were used in a Gradient Boosting Machine algorithm to predict serum creatinine-based Kidney Disease Improving Global Outcomes stage 2 acute kidney injury, with 60% of the data used for derivation and 40% for validation. Area under the receiver operator characteristic curve (AUC) was calculated in the validation cohort, and subgroup analyses were conducted across admission serum creatinine, acute kidney injury severity, and hospital location. Among the 121,158 included patients, 17,482 (14.4%) developed any Kidney Disease Improving Global Outcomes acute kidney injury, with 4,251 (3.5%) developing stage 2. The AUC (95% CI) was 0.90 (0.90-0.90) for predicting stage 2 acute kidney injury within 24 hours and 0.87 (0.87-0.87) within 48 hours. The AUC was 0.96 (0.96-0.96) for receipt of renal replacement therapy (n = 821) in the next 48 hours. Accuracy was similar across hospital settings (ICU, wards, and emergency department) and admitting serum creatinine groupings. At a probability threshold of greater than or equal to 0.022, the algorithm had a sensitivity of 84% and a specificity of 85% for stage 2 acute kidney injury and predicted the development of stage 2 a median of 41 hours (interquartile range, 12-141 hr) prior to the development of stage 2 acute kidney injury. CONCLUSIONS: Readily available electronic health record data can be used to predict impending acute kidney injury prior to changes in serum creatinine with excellent accuracy across different patient locations and admission serum creatinine. Real-time use of this model would allow early interventions for those at high risk of acute kidney injury. PMID- 29596074 TI - Psychological Impact of Pregnancy Loss: Best Practice for Obstetric Providers. AB - Three overlapping areas of study form the foundation of the psychological impact of pregnancy loss: (1) transition to parenthood and the development of attachment, (2) perinatal mental health disorders, and (3) complicated grief. This article integrates findings from prominent lineages of theory to offer the obstetric provider an evidence-based framework for patient care. Current consensus across fields of study is that preexisting depression and anxiety are the strongest predictors of psychological functioning after loss and through the subsequent pregnancy. Compassionate care, informational guidance and timed follow up positively impact patient outcomes. The article concludes with recommendations for obstetric provider training and self-care. PMID- 29596075 TI - Managing Heavy Menstrual Bleeding in Women at Risk of Thrombosis. AB - Management of heavy menstrual bleeding (HMB) in a woman with a history of thrombosis, or who is otherwise at high risk of thrombosis, or who takes medications for anticoagulation can present a challenge to health care providers. The goal of treating HMB is to reduce menstrual blood loss. First-line therapy is typically hormonal, and hormonal therapy can be contraindicated in women with a history of thrombosis unless they are on anticoagulation. As 70% of women on anticoagulation experience HMB, successful management of HMB may involve a modification in the anticoagulation or antiplatelet regimen, hormonal therapy tailored to the patient's situation, and/or surgical therapy. PMID- 29596077 TI - Anterior Cruciate Ligament Injuries in the National Hockey League: Epidemiology and Performance Impact. AB - OBJECTIVE: To determine the incidence of anterior cruciate ligament (ACL) injuries in the National Hockey League (NHL) and to examine the effects of this injury on return-to-play status and performance. DESIGN: Case series; level of evidence, 4. METHODS: This was a 2-phase study. Phase I used the NHL electronic injury surveillance system and Athlete Health Management System to collect data on ACL injuries and man games lost over 10 seasons (2006/2007-2015/2016). Data collected in phase I were received in deidentified form. Phase II examined the performance impact of an ACL injury. Players were identified through publically available sources, and performance-related statistics were analyzed. Data collected in phase II were not linked to data collected in phase I. A paired t test was used to determine any difference in the matching variables between controls and cases in the preinjury time period. A General linear model (mixed) was used to determine the performance impact. RESULTS: Phase I: 67 ACL injuries occurred over 10 seasons. The incidence for all players was 0.42/1000 player game hours (forward, 0.61; defenseman, 0.32, goalie, 0.08) and by game exposure was 0.2/1000 player game exposures (forward, 0.33; defenseman, 0.11; goalie, 0.07). Forwards had a greater incidence rate of ACL tears with both game hours and game exposures when compared with defensemen and goalies (P < 0.001, <0.001; P = 0.008, <0.001, respectively). Phase II: 70 ACL tears (60 players) were identified. Compared with controls, players who suffered an ACL tear demonstrated a decrease in goals/season (P < 0.04), goals/game (P < 0.015), points/season (0.007), and points/game (0.001). Number of games and seasons played after an ACL injury did not differ compared with controls (P = 0.068, 0.122, respectively). CONCLUSIONS: Anterior cruciate ligament injuries occur infrequently, as it relates to other hockey injuries. Despite a high return to play, the performance after an ACL injury demonstrated a decrease in points and goals per game and per season. PMID- 29596076 TI - Predictors of Postpartum Depression: A Comprehensive Review of the Last Decade of Evidence. AB - Postpartum depression (PPD) is one of the most frequent complications of childbirth affecting ~500,000 women annually (prevalence 10% to 15%). Despite the documented adverse outcomes for mother and child, there remains a great need to develop prospective approaches to identify women at risk. This review examines some of the best-characterized molecular and clinical risk factors for PPD. We illustrate that this is a growing literature but there remains a lack of reliable molecular predictors for PPD. Current best predictors are clinical assessments for psychiatric history and adverse life events, highlighting the need for increased depression screening across the perinatal period.

PMID- 29596078 TI - Reduction in postpercutaneous coronary intervention angina in addition to gastrointestinal events in patients on combined proton pump inhibitors and dual antiplatelet therapy: a systematic review and meta-analysis. AB - BACKGROUND: Primary percutaneous coronary intervention (PCI) is a standard treatment in patients with acute coronary syndrome. Studies have shown that proton pump inhibitors (PPIs) can potentially attenuate the antiplatelet effects of P2Y12 inhibitors with associated adverse cardiovascular outcomes. MATERIALS AND METHODS: Medline was searched using Pubmed from inception to 8 November 2017 for randomized control trials studying the effect of PPIs on coronary artery disease with concomitant use of dual antiplatelet therapy (DAPT). Overall, 692 studies were identified of which five randomized control trials were included. Statistical analysis was done using RevMan, version 5.3. RESULTS: Five studies with 6239 patients (3113 on PPI with DAPT and 3126 with only DAPT) were included. Our analysis showed that PPI significantly reduced the incidence of gastrointestinal (GI) bleed [22 vs. 66, odds ratio (OR)=0.37, confidence interval (CI)=0.23-0.61, P<=0.0001, I=0%], GI ulcers and GI erosions (7 vs. 18, OR=0.39, CI=0.16-0.94, P=0.04, I=0%), and the incidence of post-PCI unstable angina in patients treated with PPI and P2Y12 agents (46 vs. 67, OR=0.67, CI=0.45-0.99, P=0.05, I=0%). There was an insignificant difference in myocardial infarction, stroke, and cardiovascular cause of mortality. A trend toward decreased all-cause mortality with PPIs was noted. Heterogeneity was calculated using I. CONCLUSION: Concomitantly administered PPIs with P2Y12 inhibitors have a protective effect on the GI events. It also decreases the post-PCI angina without increased adverse cardiovascular outcomes. PMID- 29596080 TI - Low-Dose Characterization of Kidney Stones Using Spectral Detector Computed Tomography: An Ex Vivo Study. AB - OBJECTIVES: The aim of this study was to investigate the feasibility of kidney stone composition analysis using spectral detector computed tomography scanner (SDCT) with normal- and low-dose imaging protocols. METHODS: A total of 154 stones harvested from nephrolithotripsy or nephrolithotomy with a known monocrystalline composition as determined by infrared spectroscopy were examined in a nonanthropomorphic phantom on an SDCT (IQon, Philips, Best, the Netherlands). Imaging was performed with 120 kVp and (a) 40 mAs and (b) 200 mAs, resulting in a computed tomography dose index (CTDIvol) of 2 and 10 mGy, respectively. Besides conventional CT images (CIs), SDCT enables reconstruction of virtual monoenergetic images (40-200 keV). Spectral coefficient images were calculated by performing a voxel-by-voxel combination of 40 and 200 keV images (Matlab R2017b, Mathworks Inc). All stones were semiautomatically 3D-segmented on CI using a threshold-based algorithm implemented in an offline DICOM viewer. Statistical assessment was performed using Steel-Dwass method to adjust for multiple comparisons. RESULTS: Ca-phosphate (n = 22), Ca-oxalate (n = 82), cysteine (n = 20), struvite (n = 3), uric acid (n = 18), and xanthine stones (n = 9) were included in the analysis. Stone diameter ranged from 3.0 to 13.5 mm. On CI, attenuation differed significantly between calcific and noncalcific stones only (P <= 0.05), the spectral coefficient differed significantly between (//): Ca-oxalate//Ca-phosphate//cystine//struvite//uric acid//xanthine in 10 mGy protocol (all P <= 0.05). The same results were found for the 2 mGy-protocol, except that differentiation of Ca-oxalate and Ca-phosphate as well as uric acid and xanthine was not possible (P >= 0.05). CONCLUSIONS: Spectral detector CT allows for differentiation of kidney stones using semi-automatic segmentation and advanced image post-processing, even in low-dose imaging protocols. PMID- 29596081 TI - Relationships Between the ACGME Resident and Faculty Surveys and Program Pass Rates on the ABIM Internal Medicine Certification Examination. AB - PURPOSE: The Accreditation Council for Graduate Medical Education (ACGME) has surveyed residents since 2003, and faculty since 2012. Surveys are designed to assess program functioning and specify areas for improvement. The purpose of this study was to assess the association of the ACGME's resident and faculty surveys with residency-program-specific performance on the American Board of Internal Medicine (ABIM) certification exam. METHOD: Data were available from residents and faculty in 375 U.S. ACGME-accredited internal medicine programs from the 2012 2013, 2013-2014, and 2014-2015 academic years. Analysis of variance and correlations were used to examine the relationship between noncompliance with ACGME program requirements as assessed by the resident and faculty surveys, and ABIM program pass rates. RESULTS: Noncompliance reported on the resident and faculty surveys was highest for programs not meeting the ACGME program requirement of an 80% pass rate on the ABIM certification examination. This relationship was significant for overall noncompliance, both within the resident (P < .001) and faculty (P < .05) surveys, for many areas within the two surveys (correlations ranged between -.07 and -.25, and P values ranged between .20 and < .001), and for the highest levels of noncompliance across areas of the resident (P < .001) and faculty (P < .04) surveys. CONCLUSIONS: ACGME resident and faculty surveys were significantly associated with ABIM program pass rates, supporting the importance of these surveys within the ACGME's Next Accreditation System. PMID- 29596082 TI - Transformative Learning and Professional Identity Formation During International Health Electives: A Qualitative Study Using Grounded Theory. AB - PURPOSE: International health electives (IHEs) are widely available during residency and provide unique experiences for trainees. Theoretical models of professional identity formation and transformative learning may provide insight into residents' experiences during IHEs. The purpose of this study was to explore transformative learning and professional identity formation during resident IHEs and characterize the relationship between transformative learning and professional identity formation. METHOD: The authors used a constructivist grounded theory approach, with the sensitizing concepts of transformative learning and professional identity formation to analyze narrative reflective reports of residents' IHEs. The Mayo International Health Program supports residents from all specialties across three Mayo Clinic sites. In 2015, the authors collected narrative reflective reports from 377 IHE participants dating from 2001 to 2014. Reflections were coded and themes were organized into a model for transformative learning during IHEs, focusing on professional identity. RESULTS: Five components of transformative learning were identified during IHEs: a disorienting experience; an emotional response; critical reflection; perspective change; and a commitment to future action. Within the component of critical reflection, three domains relating to professional identity were identified: making a difference; the doctor-patient relationship; and medicine in its "purest form." Transformation was demonstrated through perspective change and a commitment to future action, including continued service, education, and development. CONCLUSIONS: IHEs provide rich experiences for transformative learning and professional identity formation. Understanding the components of transformative learning may provide insight into the interaction between learner, experiences, and the influence of mentors in the process of professional identity formation. PMID- 29596083 TI - The Scope of Extraprofessional Caregiving Challenges Among Early Career Faculty: Findings From a University Medical Center. AB - PURPOSE: Academic scientists work in competitive environments, and many institutions invest in career development supports. These investments may be imperiled when extraprofessional demands challenge a faculty member's reserve capacity. This research assessed prevalence of caregiving challenges and estimated incidence of stressful life events. METHOD: In 2015-2016, the authors surveyed recipients of career development awards supporting >= 75% effort and individuals within the funding period of their first National Institutes of Health R01 or equivalent at Vanderbilt University Medical Center. Domains included family structure, hospitalizations of family members, responsibility for coordination of caregiving, and an inventory of stressful life events. RESULTS: Seventy-two percent (152 of 210) of early career researchers responded. Over half endorsed experiencing one or more substantial caregiving challenges in the prior year. This included 35 (23%) having a child or adult in the household hospitalized in the prior year and 36 (24%) being responsible for health care needs for a child or adult in the household, or for coordinating elder care, assisted living, or hospice care. The majority experienced one or more caregiving challenges. Stressful life events increased relative risk of "thinking about leaving academics" by 70% (risk ratio: 1.7; 95% confidence interval: 1.2, 2.4). Prevalence and incidence of caregiving demands did not differ by gender. CONCLUSIONS: Leaders, administrators, mentors, and faculty should anticipate that most women and men early career researchers will experience substantial caregiving challenges and life events in any given year. Sufficient need exists to warrant investigation of institutional programs to address caregiving challenges. PMID- 29596084 TI - Combined Surgery and Intraoperative Sclerotherapy for Vascular Malformations of the Head/Neck: The Hybrid Approach. AB - Vascular malformations (VMs) of the head and neck can lead to aesthetic problems as well as cranial nerve damage, airway compromise, and vision loss. Large VMs are typically managed surgically, with sclerotherapy or embolization performed in the perioperative period to decrease the risk of excessive blood loss and minimize the size of the VM. However, this initial treatment is frequently insufficient leading to excessive blood loss intraoperatively, poorer margin visualization for the surgeon, and decreased likelihood of complete resection. As a result, resections of large VMs are often performed in a multistage approach. This article introduces a new hybrid approach for the management of head and neck VMs entailing the use of an endovascular operating room where a neuroendovascular surgeon performs embolization or sclerotherapy intraoperatively as needed in conjunction with surgical excision. Three patients with large VMs in the facial region underwent successful use of the hybrid approach. The hybrid approach improved visualization, leading to complete resection in 1 patient and nearly complete resections (70% and 90%) in the other patients. The technique also helped minimize blood loss because only the youngest patient (23 months old) required a blood transfusion. Implications of these findings include the transition from a multistaged approach for large VMs to a single-stage approach. In addition, decreases in blood loss may allow for the development and use of minimal access techniques, leading to a decrease in visible scarring for patients. We suggest the consideration of the hybrid approach for large head and neck VMs. PMID- 29596085 TI - The Influence of Connective Tissue Disease in Breast Reconstruction: A National Database Analysis. AB - BACKGROUND: Patients with connective tissue diseases (CTD), or collagen vascular diseases, are at risk of potentially higher morbidity after surgical procedures. We aimed to investigate the complication profile in CTD versus non-CTD patients who underwent breast reconstruction on a national scale. METHODS: A retrospective analysis of the Healthcare Cost and Utilization Project NIS Database between 2010 and 2014 was conducted for patients 18 years or older admitted for immediate autologous or implant breast reconstruction. Connective tissue disease was defined as systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, scleroderma, Raynaud phenomenon, psoriatic arthritis, or sarcoidosis. Independent t test/Wilcoxon-Mann-Whitney was used to compare continuous variables and Pearson chi/Fischer exact test was used for categorical variables. Outcomes of interest were assessed using multivariable linear regressions for continuous variables and multivariable logistic regressions for categorical variables. RESULTS: There were 19,496 immediate autologous breast reconstruction patients, with 357 CTD and 19,139 non-CTD patients (2010-2014). The CTD patients had higher postoperative complication rates for infection (2.8% vs 0.8%, P < 0.001), wound dehiscence (1.4% vs 0.4%, P = 0.019), and bleeding (hemorrhage and hematoma) (6.7% vs 3.5%, P < 0.001). After multivariable analysis, CTD remained an independent risk factor for bleeding (odds ratio [OR], 1.568; 95% confidence interval [CI], 1.019-2.412). There were a total of 23,048 immediate implant breast reconstruction patients, with 431 CTD and 22,617 non-CTD patients (2010 2014). The CTD patients had a higher postoperative complication rate for wound dehiscence/complication (2.3% vs 0.6%, P < 0.001). They also experienced a longer length of stay (2.31 days vs 2.07 days, P < 0.001). After multivariable analysis, CTD remained an independent risk factor for wound dehiscence (OR, 4.084; 95% CI, 2.101-7.939) and increased length of stay by 0.050 days (95% CI, -0.081 to 0.181). CONCLUSIONS: Connective tissue disease patients who underwent autologous breast reconstruction had significantly higher infection, wound dehiscence, and bleeding rates, and those who underwent implant breast reconstruction had significantly higher wound dehiscence rates. Connective tissue diseases appear to be an independent risk factor for bleeding and wound dehiscence in autologous and implant breast reconstruction, respectively. This information may help clinicians be aware of this increased risk when determining patients for reconstruction. PMID- 29596086 TI - Work/Life Balance: It Is Just Plain Hard. AB - Graduating surgeons are constantly told to be "available, affable, and able." Frequently, the need to put patients first can result in an imbalance between work and life. Ultimately, the consequence of work/life imbalance is burnout, which can manifest itself in atypical behavior toward patients, colleagues, and family. It is imperative that all surgeons learn to take care of themselves and develop a better integration of work and life. PMID- 29596087 TI - Analysis of Follicle-Stimulating Hormone Receptor in Infantile Hemangioma. AB - INTRODUCTION: The life cycle of infantile hemangioma (IH) and secretion of follicle-stimulating hormone (FSH) are identical. We previously have shown that IH contains the FSH receptor (FSHR). The purpose of this study was to identify which cell type(s) in IH expresses FSHR. METHODS: Human proliferating IH tissues obtained during a clinically indicated surgical procedure were used. Paraffin sections and isolated cell populations (endothelial, pericyte, stem cell) were subjected to immunofluorescence for FSHR. Tissues were costained with DAPI, anti alpha smooth muscle actin, or biotinylated Ulex Europaeus Agglutinin I to identify nuclei, pericytes, and endothelial cells, respectively. Whole tissue and purified single cell populations underwent polymerase chain reaction (PCR) for FSHR. Positive control specimens (ovary, sertoli cells) and negative control tissues (skin/subcutis, hepatic cells) were included. RESULTS: Immunofluorescence of 9 IHs demonstrated that FSHR was enriched in pericytes compared with endothelial cells. Follicle-stimulating hormone receptor was expressed in 6 of 6 whole tissue IHs along with the positive control via PCR. Follicle-stimulating hormone receptor was not present in the negative control samples. Four of 5 sets of pericytes expressed FSHR by PCR. Neither IH endothelial cells, IH stem cells, nor negative control cells exhibited FSHR by PCR. CONCLUSIONS: Because the secretion of FSH correlates with the growth pattern of IH, FSH might be involved in the disease process. Follicle-stimulating hormone receptor is enriched in the pericytes of IH, suggesting that this cell type may be involved in the pathogenesis of the tumor. PMID- 29596088 TI - A Systematic Review of Prognostic Factors for Sensory Recovery After Digital Nerve Reconstruction. AB - BACKGROUND: Successful digital nerve repair is crucial in preventing painful neuroma formation and restoring sensory function after traumatic hand injury. The purpose of this study is to identify prognostic factors affecting sensory recovery following digital nerve reconstruction. METHODS: A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines including studies reporting patients 18 years and older, greater than 10 reconstructed digital nerves, and greater than or equal to 3 months follow-up. Studies with proximal nerve injuries in the same distribution or inadequate sensory data were excluded. Included studies were evaluated by methodological index for nonrandomized studies score. Possible predictors were examined using the t test and 1-way analysis of variance with alpha <= 0.05. RESULTS: Twenty-five studies met the inclusion criteria, consisting of 818 surgically reconstructed digital nerves (mean age, 38 years; 78% male) with a mean +/- SD defect length of 1.5 +/- 0.5 cm. Mean follow-up time was 22 months. Fifty-six percent of patients presented with concomitant injuries to tendons (31%) and the digital artery (13%). Mean +/- SD time to surgical repair was 36 +/ 73.8 days. Reconstructive techniques included 35% end-to-end primary neurorrhaphy, 31% nerve grafts, and 11% synthetic conduits. Postoperatively, 81% of the patients demonstrated sensory recovery of S3+/S4, with 45% complaining of hyperesthesia. Nerve reconstructions performed within 15 days of injury had significantly better static 2-point discrimination than delayed procedures (P = 0.02). Static 2-point discrimination measurements were also significantly better for shorter defect lengths (<1.3 cm, P = 0.05). No significant functional differences were found across age, follow-up time, injured digit or side, nor reconstructive technique. CONCLUSIONS: Digital nerve reconstruction has good to excellent sensory recovery in up to 81% of patients with improved results in nerve gaps less than 1.3 cm. Performing the reconstruction within 15 days of injury is also correlated with improved sensory recovery. PMID- 29596089 TI - The Unexpected Life: Living With Hand Transplant. PMID- 29596090 TI - Using Mesh to Reinforce the Abdominal Wall in Abdominal Free Flaps for Breast Reconstruction: Is There a Benefit? What are the Risks? AB - INTRODUCTION: Abdominal wall integrity may be compromised after abdominal flap harvest for breast reconstruction, leading to bulging or herniation due to weakening of the abdominal wall and dissection through the rectus muscle. Mesh can be used to reinforce the abdominal wall to reduce the risk of hernia formation postoperatively, especially in patients who may be at high risk. In this study, we describe this institution's experience with the use of mesh in the abdominal wall and critically evaluate its impact on patient outcomes and complications. METHODS: We retrospectively reviewed all patients with an abdominal free flap harvested for breast reconstruction at Stanford Health Care from 2005 to 2015. Multivariate-adjusted logistic regression analysis was used to compare the odds of abdominal complications-infection, bulging, and herniation between patients with and without an abdominal mesh implanted during breast reconstruction. RESULTS: Three hundred eighty patients met inclusion criteria. One hundred sixty-one patients received mesh, whereas 219 received no reinforcement. In the mesh group, there were 7 (4.3%) cases of postoperative abdominal bulging, 11 (6.8%) cases of abdominal infection, and no (0.0%) cases of herniation. In the group without mesh, there were 17 (7.8%) cases of abdominal bulging, 11 (5.0%) cases of abdominal infection, and 5 (2.3%) cases of herniation. There was a significant difference in the odds of bulging (odds ratio [OR], 0.30; P = 0.01). There was not a significant difference in the odds of herniation (OR, 2.26E-10; P = 0.99) or infection (OR, 1.21; P = 0.69). CONCLUSIONS: In our current treatment algorithm, patients who received mesh were selected based upon several criteria, including obesity, weak fascia identified during surgery, and extensive muscle dissection. We confirm that the risk of bulging and herniation is decreased in patients receiving mesh. Furthermore, the risk of wound infection was not associated with the use of mesh; instead, a patient's elevated body mass index, as well as tension of closure, and other comorbidities are more likely causes of superficial wound complications. We find the use of mesh to be safe and beneficial in select patients undergoing abdominal free flap breast reconstruction who are at risk for hernias and bulges.

PMID- 29596092 TI - The Impact of Postreperfusion Syndrome on Acute Kidney Injury in Living Donor Liver Transplantation: A Propensity Score Analysis. AB - BACKGROUND: Postreperfusion syndrome (PRS) has been shown to be related to postoperative morbidity and graft failure in orthotopic liver transplantation. To date, little is known about the impact of PRS on the prevalence of postoperative acute kidney injury (AKI) and the postoperative outcomes after living donor liver transplantation (LDLT). The purpose of our study was to determine the impact of PRS on AKI and postoperative outcomes after LDLT surgery. METHODS: Between January 2008 and October 2015, we retrospectively collected and evaluated the records of 1865 patients who underwent LDLT surgery. We divided the patients into 2 groups according to the development of PRS: PRS group (n = 715) versus no PRS group (n = 1150). Risk factors for AKI and mortality were investigated by multivariable logistic and Cox proportional hazards regression model analysis. Propensity score (PS) analysis (PS matching and inverse probability of treatment weighting analysis) was designed to compare the outcomes between the 2 groups. RESULTS: The prevalence of PRS and the mortality rate were 38% and 7%, respectively. In unadjusted analyses, the PRS group showed more frequent development of AKI (P < .001), longer hospital stay (P = .010), and higher incidence of intensive care unit stay over 7 days (P < .001) than the no PRS group. After PS matching and inverse probability of treatment weighting analysis, the PRS group showed a higher prevalence of postoperative AKI (P = .023 and P = .017, respectively) and renal dysfunction 3 months after LDLT (P = .036 and P = .006, respectively), and a higher incidence of intensive care unit stay over 7 days (P = .014 and P = .032, respectively). CONCLUSIONS: We demonstrated that the magnitude and duration of hypotension caused by PRS is a factor contributing to the development of AKI and residual renal dysfunction 3 months after LDLT. PMID- 29596093 TI - Anesthetics Influence Mortality in a Drosophila Model of Blunt Trauma With Traumatic Brain Injury. AB - BACKGROUND: Exposure to anesthetics is common in the majority of early survivors of life-threatening injuries. Whether and to what degree general anesthetics influence outcomes from major trauma is unknown. Potential confounding effects of general anesthetics on outcome measures are usually disregarded. We hypothesized that exposure to isoflurane or sevoflurane modulates the outcome from blunt trauma with traumatic brain injury (bTBI). METHODS: We tested the hypothesis in a novel model of bTBI implemented in Drosophila melanogaster. Fruit flies of the standard laboratory strain w were cultured under standard conditions. We titrated the severity of bTBI to a mortality index at 24 hours (MI24) of approximately 20% under control conditions. We administered standard doses of isoflurane and sevoflurane before, before and during, or after bTBI and measured the resulting MI24. We report the MI24 as mean +/- standard deviation. RESULTS: Isoflurane or sevoflurane administered for 2 hours before bTBI reduced the MI24 from 22.3 +/- 2.6 to 10.4 +/- 1.8 (P < 10, n = 12) and from 19.3 +/- 0.9 to 8.9 +/- 1.1 (P < .0001, n = 8), respectively. In contrast, administration of isoflurane after bTBI increased the MI24 from 18.5% +/- 4.3% to 25.3% +/- 9.1% (P = .0026, n = 22), while sevoflurane had no effect (22.4 +/- 7.1 and 21.5 +/- 5.8, n = 22). CONCLUSIONS: In a whole animal model of bTBI, general anesthetics were not indifferent with respect to early mortality. Therefore, collateral effects of general anesthetics should be considered in the interpretation of results obtained in vertebrate trauma models. Invertebrate model organisms can serve as a productive platform to interrogate anesthetic targets that mediate collateral effects and to inform trauma research in higher organisms about the potential impact of anesthetics on outcomes. PMID- 29596094 TI - Database Quality and Access Issues Relevant to Research Using Anesthesia Information Management System Data. AB - For this special article, we reviewed the computer code, used to extract the data, and the text of all 47 studies published between January 2006 and August 2017 using anesthesia information management system (AIMS) data from Thomas Jefferson University Hospital (TJUH). Data from this institution were used in the largest number (P = .0007) of papers describing the use of AIMS published in this time frame. The AIMS was replaced in April 2017, making this finite sample finite. The objective of the current article was to identify factors that made TJUH successful in publishing anesthesia informatics studies. We examined the structured query language used for each study to examine the extent to which databases outside of the AIMS were used. We examined data quality from the perspectives of completeness, correctness, concordance, plausibility, and currency. Our results were that most could not have been completed without external database sources (36/47, 76.6%; P = .0003 compared with 50%). The operating room management system was linked to the AIMS and was used significantly more frequently (26/36, 72%) than other external sources. Access to these external data sources was provided, allowing exploration of data quality. The TJUH AIMS used high-resolution timestamps (to the nearest 3 milliseconds) and created audit tables to track changes to clinical documentation. Automatic data were recorded at 1-minute intervals and were not editable; data cleaning occurred during analysis. Few paired events with an expected order were out of sequence. Although most data elements were of high quality, there were notable exceptions, such as frequent missing values for estimated blood loss, height, and weight. Some values were duplicated with different units, and others were stored in varying locations. Our conclusions are that linking the TJUH AIMS to the operating room management system was a critical step in enabling publication of multiple studies using AIMS data. Access to this and other external databases by analysts with a high degree of anesthesia domain knowledge was necessary to be able to assess the quality of the AIMS data and ensure that the data pulled for studies were appropriate. For anesthesia departments seeking to increase their academic productivity using their AIMS as a data source, our experiences may provide helpful guidance. PMID- 29596095 TI - Dexamethasone as an Adjuvant for Caudal Blockade in Pediatric Surgical Patients: A Systematic Review and Meta-analysis. AB - BACKGROUND: Caudal block is commonly used to provide postoperative analgesia after pediatric surgery in the lower abdomen. Typically administered as a single shot technique, 1 limitation of this block is the short duration of analgesia. To overcome this, dexamethasone has been used as an adjuvant to prolong block duration. However, there are concerns about steroid-related morbidity and the optimal route of dexamethasone administration (eg, caudal or intravenous) is unknown. METHODS: We conducted a systematic review and random-effects meta analysis of randomized controlled trials recruiting pediatric surgical patients receiving a caudal block for surgical anesthesia or postoperative analgesia. Included studies compared dexamethasone (caudal, intravenous, or both) to control. Duration of analgesia was the primary outcome. Database sources were Medline, Embase, the Cochrane Library, and Google Scholar searched up to August 18, 2017, without language restriction. Screening of studies, data extraction, and risk of bias assessment were performed independently and in duplicate by 2 authors. Risk of bias was assessed using Cochrane methodology and the strength of evidence was scored using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS: The initial search retrieved 93 articles. Fourteen randomized controlled trials that comprised 1315 pediatric patients met the inclusion criteria. All but 1 study involved lower abdominal operations (orchidopexy, inguinal hernia repair, and hypospadias repair). The caudal and intravenous dose of dexamethasone ranged from 0.1 to 0.2 mg/kg and 0.5 to 1.5 mg/kg, respectively, and all studies were pooled in the main analysis. Dexamethasone prolonged the duration of analgesia by both the caudal route (5.43 hours, 95% confidence interval [CI], 3.52-7.35; P < .001; I = 99.3%; N = 9; n = 620; GRADE quality = moderate) and intravenous route (5.51 hours; 95% CI, 3.56 7.46; P < .001; I = 98.9%; N = 5; n = 364; GRADE quality = moderate) versus control. Secondary benefits of dexamethasone included reduced narcotic rescue analgesia requirement in the postanesthetic care unit (relative risk [RR], 0.30; 95% CI, 0.18-0.51; P < .001; I = 0.0%; N = 5; number needed to treat for benefit [NNTB] = 5; 95% CI, 4-7), less subsequent postoperative rescue analgesia requirement (RR, 0.46; 95% CI, 0.23-0.92; P = .03; I = 96.0%; N = 9; n = 629; NNTB = 3; 95% CI, 2-20; n = 310), and lower rates of postoperative nausea and vomiting (RR, 0.47; 95% CI, 0.30-0.73; P = .001; I = 0.0%; NNTB = 11; 95% CI, 8 21; N = 9; n = 628). Adverse events linked to the dexamethasone were rare. CONCLUSIONS: Caudal and intravenous dexamethasone are similarly effective for prolonging the duration of analgesia from caudal blockade, resulting in a doubled to tripled duration. Given the off-label status of caudal dexamethasone, intravenous administration is recommended-although only high intravenous doses (0.5 mg/kg up to 10 mg) have been studied. PMID- 29596096 TI - Time for a Fresh Approach to Examining Factors Associated With Red Blood Cell Transfusion Outcome. PMID- 29596097 TI - Repeated Morphine Prolongs Postoperative Pain in Male Rats. AB - BACKGROUND: Opioids are effective postoperative analgesics. Disturbingly, we have previously reported that opioids such as morphine can worsen inflammatory pain and peripheral and central neuropathic pain. These deleterious effects are mediated by immune mediators that promote neuronal hyperexcitability in the spinal dorsal horn. Herein, we tested whether perioperative morphine could similarly prolong postoperative pain in male rats. METHODS: Rats were treated with morphine for 7 days, beginning immediately after laparotomy, while the morphine was tapered in a second group. Expression of genes for inflammatory mediators was quantified in the spinal dorsal horn. In the final experiment, morphine was administered before laparotomy for 7 days. RESULTS: We found that morphine treatment after laparotomy extended postoperative pain by more than 3 weeks (time * treatment: P < .001; time: P < .001; treatment: P < .05). Extension of postoperative pain was not related to morphine withdrawal, as it was not prevented by dose tapering (time * treatment: P = .8; time: P < .001; treatment: P = .9). Prolonged postsurgical pain was associated with increased expression of inflammatory genes, including those encoding Toll-like receptor 4, NOD like receptor protein 3 (NLRP3), nuclear factor kappa B (NFkappaB), caspase-1, interleukin-1beta, and tumor necrosis factor (P < .05). Finally, we showed that of preoperative morphine, concluding immediately before laparotomy, similarly prolonged postoperative pain (time * treatment: P < .001; time: P < .001; treatment: P < .001). There is a critical window for morphine potentiation of pain, as a 7-day course of morphine that concluded 1 week before laparotomy did not prolong postsurgical pain. CONCLUSIONS: These studies indicate the morphine can have a deleterious effect on postoperative pain. These studies further suggest that longitudinal studies could be performed to test whether opioids similarly prolong postoperative pain in the clinic. PMID- 29596098 TI - A Dedicated Acute Pain Service Is Associated With Reduced Postoperative Opioid Requirements in Patients Undergoing Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy. AB - BACKGROUND: The Acute Pain Service (APS) was initially introduced to optimize multimodal postoperative pain control. The aim of this study was to evaluate the association between the implementation of an APS and postoperative pain management and outcomes for patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). METHODS: In this propensity-matched retrospective cohort study, we performed a before-after study without a concurrent control group. Outcomes were compared among patients undergoing CRS-HIPEC when APS was implemented versus historical controls (non APS). The primary objective was to determine if there was a decrease in median total opioid consumption during postoperative days 0-3 among patients managed by the APS. Secondary outcomes included opioid consumption on each postoperative day (0-6), time to ambulation, time to solid intake, and hospital length of stay. RESULTS: After exclusion, there were a total of 122 patients, of which 51 and 71 were in the APS and non-APS cohort, respectively. Between propensity-matched groups, the median (quartiles) total opioid consumption during postoperative days 0-3 was 27.5 mg intravenous morphine equivalents (MEQs) (7.6-106.3 mg MEQs) versus 144.0 mg MEQs (68.9-238.3 mg MEQs), respectively. The median difference was 80.8 mg MEQs (95% confidence interval, 46.1-124.0; P < .0001). There were statistically significant decreases in time to ambulation and time to solid diet intake in the APS cohort. CONCLUSIONS: After implementing the APS, CRS-HIPEC patients had decreased opioid consumption by >50%, as well as shorter time to ambulation and time to solid intake. Implementation of an APS may improve outcomes in CRS-HIPEC patients. PMID- 29596099 TI - Evidence Basis for Regional Anesthesia in Ambulatory Anterior Cruciate Ligament Reconstruction: Part I-Femoral Nerve Block. AB - The optimal management of pain after ambulatory anterior cruciate ligament reconstruction (ACLR) is unclear. Femoral nerve block (FNB) is purported to enhance postoperative analgesia, but its effectiveness in the setting of modern multimodal analgesia is unclear. This systematic review examines the effect of adding FNB to multimodal analgesia on analgesic outcomes after ACLR, whether or not the analgesic regimen used included local instillation analgesia (LIA). We retrieved randomized controlled trials evaluating the effects of adding FNB to multimodal analgesia on analgesic outcomes after ACLR, compared to multimodal analgesia alone (control). We designated postoperative opioid consumption at 24 hours as our primary outcome. Secondary outcomes included postoperative opioid consumption at 24-48 hours, rest, and dynamic pain severity between 0 and 48 hours, time to analgesic request, postanesthesia care unit and hospital stay durations, patient satisfaction, postoperative nausea and vomiting, functional outcomes, and long-term (>1 month) quadriceps strength. Eight randomized controlled trials (716 patients) were identified. Five trials compared FNB administration to control, and another 3 compared the combination of FNB and LIA to LIA alone. Compared to control, adding FNB resulted in modest reductions in 24 hour opioid consumption in 2 of 3 trials, and improvements in rest pain at 1 hour in 1 trial and up to 24 hours in another. In contrast, the combination of FNB and LIA, compared to LIA alone, did not reduce opioid consumption in any of the trials, but it did improve pain scores at 20 minutes only in 1 trial. The effect of FNB on long-term quadriceps strength or function after ACLR was not evaluated in the reviewed trials. Contemporary evidence suggests that the benefits of adding FNB to multimodal analgesia for ACLR are modest and conflicting, but there is no incremental analgesic benefit if the multimodal analgesic regimen included LIA. Our findings do not support the routine use of FNB for analgesia in patients having ACLR. PMID- 29596100 TI - Determination of Geolocations for Anesthesia Specialty Coverage and Standby Call Allowing Return to the Hospital Within a Specified Amount of Time. AB - BACKGROUND: For emergent procedures, in-house teams are required for immediate patient care. However, for many procedures, there is time to bring in a call team from home without increasing patient morbidity. Anesthesia providers taking subspecialty or backup call from home are required to return to the hospital within a designated number of minutes. Driving times to the hospital during the hours of call need to be considered when deciding where to live or to visit during such calls. Distance alone is an insufficient criterion because of variable traffic congestion and differences in highway access. We desired to develop a simple, inexpensive method to determine postal codes surrounding hospitals allowing a timely return during the hours of standby call. METHODS: Pessimistic travel times and driving distances were calculated using the Google distance matrix application programming interface for all N= 136 postal codes within 60 great circle ("straight line") miles of the University of Miami Hospital (Miami, FL) during all 108 weekly standby call hours. A postal code was acceptable if the estimated longest driving time to return to the hospital was <=60 minutes (the anesthesia department's service commitment to start an urgent case during standby call). Linear regression (with intercept = 0) minimizing the mean absolute percentage difference between the distances (great circle and driving) and the pessimistic driving times to return to the hospital was performed among all 136 postal codes. Implementation software written in Python is provided. RESULTS: Postal codes allowing return to the studied hospital within the specified interval were identified. The linear regression showed that driving distances correlated poorly with the longest driving time to return to the hospital among the 108 weekly call hours (mean absolute percentage error = 25.1% +/- 1.7% standard error [SE]; N = 136 postal codes). Great circle distances also correlated poorly (mean absolute percentage error = 28.3% +/- 1.9% SE; N = 136). Generalizability of the method was determined by successful application to a different hospital in a rural state (University of Iowa Hospital). CONCLUSIONS: The described method allows identification of postal codes surrounding a hospital in which personnel taking standby call could be located and be able to return to the hospital during call hours on every day of the week within any specified amount of time. For areas at the perimeter of the acceptability, online distance mapping applications can be used to check driving times during the hours of standby call. PMID- 29596101 TI - Intravenous Acetaminophen Does Not Reduce Inpatient Opioid Prescription or Opioid Related Adverse Events Among Patients Undergoing Spine Surgery. AB - BACKGROUND: Having entered the US market relatively recently, the perioperative role of intravenous acetaminophen (ivAPAP) remains to be established for several surgeries. Using national data, we therefore assessed current utilization and whether it reduces inpatient opioid prescription and opioid-related side effects in a procedure with relatively high opioid utilization. METHODS: Patients undergoing a lumbar/lumbosacral spinal fusion (n = 117,269; 2011-2014) were retrospectively identified in a nationwide database and categorized by the amount and timing of ivAPAP administration (1 or >1 dose on postoperative day [POD] 0, 1, or 1+). Multivariable models measured associations between ivAPAP utilization categories and opioid prescription and perioperative complications; odds ratios (or % change) and 95% confidence intervals are reported. RESULTS: Overall, ivAPAP was used in 18.9% (n = 22,208) of cases of which 1 dose on POD 0 was the most common (73.6%; n = 16,335). After covariate adjustment, use of ivAPAP on POD 0 and 1 was associated with minimal changes in opioid prescription, length and cost of hospitalization particularly favoring >1 ivAPAP dose with a modestly (-5.2%, confidence interval, -7.2% to -3.1%; P < .0001) decreased length of stay. Use of ivAPAP did not coincide with a consistent pattern of significantly reduced odds for complications. In comparison, the most commonly used nonopioid analgesic, pregabalin/gabapentin, did demonstrate reduced opioid prescription combined with lower complication risk. CONCLUSIONS: We could not show that perioperative ivAPAP reduces inpatient opioid prescription with subsequent reduced odds for adverse outcomes. It remains to be determined if and under what circumstances ivAPAP has a meaningful clinical role in everyday practice. PMID- 29596102 TI - Clonidine Effect on Pain After Cesarean Delivery: A Randomized Controlled Trial of Different Routes of Administration. AB - BACKGROUND: Intrathecal clonidine prolongs spinal anesthesia. We evaluated the effects of the addition of intrathecal or intravenous clonidine (75 ug) to standard cesarean delivery spinal anesthesia on postoperative pain and neonatal outcomes. METHODS: In a randomized, placebo-controlled, double-blind trial, 64 women scheduled for elective cesarean delivery under spinal anesthesia were randomly allocated and compared among 3 groups: intrathecal clonidine 75 ug, intravenous clonidine 75 ug, and placebo. The primary outcome was acute postoperative pain. A sample size of 26 individuals per group (N = 78) was planned. RESULTS: From April 2015 to April 2016, 64 women were analyzed (14 excluded). No differences in postoperative pain scores were found (Numerical Verbal Scale for pain at movement at 24 hours of postcesarean delivery: 4.53 +/- 3.0 vs 4.45 +/- 2.73 vs 3.93 +/- 3.07 for control, intrathecal, and intravenous, respectively, P = .771). Intrathecal and intravenous clonidine led to more sedation, in comparison to the control group, during the intraoperative period (Richmond Agitation and Sedation Scale: -0.3 +/- 0.47 vs -1 +/- 0.53 vs -0.73 +/- 0.45 for control, intrathecal, and intravenous, respectively, overall P < .001; Dunn correction: P < .001 for intrathecal versus control; P = .021 for intravenous versus control; and P = .208 for intrathecal versus intravenous). CONCLUSIONS: Intrathecal or intravenous clonidine had no effect on postoperative pain after cesarean delivery. Both intrathecal and intravenous clonidine caused more sedation. PMID- 29596103 TI - Changes in International Normalized Ratios After Plasma Transfusion of Varying Doses in Unique Clinical Environments. AB - BACKGROUND: Plasma transfusion is commonly performed for the correction of abnormal coagulation screening tests. The goal of this investigation was to assess the relationship between the dose of plasma administered and changes in coagulation test results in a large and diverse cohort of patients with varying levels of coagulation abnormalities and comorbid disease and in a variety of clinical settings. METHODS: In this single-center historical cohort study, all plasma transfusion episodes in adult patients with abnormal coagulation screening tests were extracted between 2011 and 2015. The primary outcome was the proportion of patients attaining normal posttransfusion international normalized ratio (INR <= 1.1) with secondary outcomes including the proportion of patients attaining partial normalization of INR (INR <= 1.5) or at least 50% normalization in pretransfusion values with respect to an INR of 1.1. RESULTS: In total, 6779 unique patients received plasma with a median (quartiles) pretransfusion INR of 1.9 (1.6-2.5) and a median transfusion volume of 2 (2-3) units. The majority (85%) of transfusions occurred perioperatively, with 20% of transfusions administered prophylactically before a procedure. The median decrease in INR was 0.4 (0.2-0.8). Complete INR normalization was obtained in 12%. Reductions in INR were modest with pretransfusion INR values <3. Patients receiving >=3 units of plasma were more likely to achieve at least 50% normalization in INR than those receiving <=2 units (68% vs 60%; P < .001). CONCLUSIONS: Changes in INR after plasma transfusion were modest at typically used clinical doses, particularly in those with less severely deranged baseline coagulation screening tests. Further studies are necessary to assess the relationships between plasma-mediated changes in INR and clinical outcomes. PMID- 29596104 TI - Simulation to Prepare Graduate Nursing Students for Clinical Faculty Role. AB - Limited clinical sites and faculty to teach graduate students to be undergraduate clinical faculty have led to the exploration of innovative teaching strategies. This article describes and evaluates a simulation experience to supplement didactic learning about best clinical teaching practices within a graduate nursing course. Scenarios were created to simulate complex teaching situations with a patient, an undergraduate nursing student, and a clinical faculty member. Evaluations were positive regarding knowledge, performance, self-confidence, critical thinking, and satisfaction. Results of this project support the use of simulation in the preparation of graduate nursing students to become clinical faculty. PMID- 29596105 TI - Attention Health Care Leaders: Literature Review Deems Baccalaureate Nurses Improve Patient Outcomes. AB - AIM: This review of studies conducted since the 2011 publication of the Institute of Medicine (IOM) report "The Future of Nursing: Leading Change, Advancing Health" evaluates the current state of evidence showing an association between an increased ratio of BSN-prepared nursing staff and improved patient outcomes. BACKGROUND: The IOM established a nationwide goal to increase the number of BSN nurses to 80 percent by 2020 to meet the challenges seen in today's health care environment. METHOD: The literature search included a five-year (2011-2016) span following the initial release of the IOM report. RESULTS: Mortality, failure to rescue, and readmission rates all decrease as the proportion of BSN nurses is increased in a nursing staffing ratio. CONCLUSION: It is the recommendation of this project that nurse leaders and organizations support the findings of this literature review and the IOM BSN recommendation. PMID- 29596106 TI - Recombinant Human Soluble Thrombomodulin Contributes to Reduced Mortality in Sepsis Patients with Severe Respiratory Failure: A Retrospective Observational Study Using a Multicenter Dataset. AB - BACKGROUND: Recombinant human soluble thrombomodulin (rhTM) is a novel class therapeutic agent for managing disseminated intravascular coagulation. The progression of severe respiratory failure may be related to intra-alveolar coagulation/fibrinolytic disorders. We aimed to determine the efficacy of rhTM in treating sepsis patients with severe respiratory failure. METHODS: We performed a retrospective observational study using an existing dataset collected from 42 intensive care units (ICUs) in Japan. Of 3195 patients with severe sepsis or septic shock from the dataset, we selected sepsis patients with severe respiratory failure, and compared patient outcomes based on the administration of rhTM (rhTM group and no rhTM group). Propensity score analysis was performed between the 2 groups. Outcomes of interest were ICU mortality, hospital mortality, and ventilator-free days (VFDs). RESULTS: In this study, 1180 patients (rhTM, n = 356; no rhTM, n = 824) were analyzed. After adjusting for baseline imbalances with propensity-score matching, the survival-time analysis revealed a significant difference between the 2 groups (hazard ratio, 0.654; 95% confidence interval, 0.439-0.974, P = 0.03). ICU mortality was lower in the rhTM group (rhTM: 22.1% (33/149) vs. no rhTM: 36.2% (54/149), P = 0.01). Hospital mortality was also lower in the rhTM group (35.6% (53/149) vs. 49.7% (74/149), P = 0.02). VFDs trended to be higher in the rhTM group than the no rhTM group. (12.8 +/- 10.1 days vs. 10.6 +/- 10.6 days, P = 0.09). CONCLUSIONS: Administration of rhTM was positively correlated with a reduction in mortality in sepsis patients with severe respiratory failure. PMID- 29596107 TI - TMC120 displayed potent cytotoxic effect on human cervical carcinoma through enhancing the polymerization of microtubules. AB - OBJECTIVE: In the post-HAART era, the incidence of some AIDS-defining cancers declined markedly likely reflecting HAART-related improvements in immunity, whereas incidence of some cancers such as cervical cancer has not been affected. Therefore, it is valuable to find whether antiretroviral drugs or prophylactic microbicides could treat or prevent these cancers, especially the cervical cancer. DESIGN: We screened the anti-HIV drugs, approved or in phase III clinical trials, to identify a potential anticancer drug candidate. METHODS: We chose cervical HeLa and SiHa cancer cells and focused on studying the antitumor effects in vitro and in vivo. Cell proliferation was measured by MTT assay, the cytotoxic effect was obtained through apoptosis as evidenced by Annexin V flow cytometry assay because of the arresting of cancer cells in G2/M phase of cell cycle. Nude mice xenograft model was performed to detect the antitumor effect in vivo. RESULTS: TMC120 was identified as a potential anticancer drug candidate. TMC120 displayed potent cytotoxic effect on various human cancer cells, including cervical carcinoma cell line HeLa and SiHa. Further mechanism study showed that TMC120 enhanced the polymerization of microtubules, which was followed by mitotic arrest, as well as abnormal mitotic spindles. TMC120 also substantially retarded the growth rate of the tumor in vivo. CONCLUSION: TMC120 is a potential chemoprophylactic and therapeutic agent for cervical cancers in a manner similar to paclitaxel, and could be suitable for helping healthy women to prevent HIV infection and cervical cancer. PMID- 29596108 TI - Hepatocellular carcinoma after sustained virological response with interferon free regimens in HIV/hepatitis C virus-coinfected patients. AB - OBJECTIVE: To assess the possible association between the use of direct antiviral agents (DAA) and the risk of hepatocellular carcinoma (HCC) in HIV/hepatitis C virus (HCV)-coinfected patients. METHODS: The GEHEP-002 cohort recruits HCC cases in HIV-infected patients from 32 centers from Spain. Three analyses were performed: the proportion of HCC cases after sustained virological response (SVR) and the evolution of this proportion over time, the frequency of HCC after SVR in HIV/HCV-coinfected patients with cirrhosis, and the probability of HCC recurrence after curative therapies among those undergoing HCV therapy. RESULTS: Forty-two (13%) out of 322 HCC cases in HIV/HCV-coinfected patients occurred after SVR. Twenty-eight (10%) out of 279 HCC cases diagnosed during the years of use of IFN based regimens occurred after SVR whereas this occurred in 14 (32.6%) out of the 43 HCC cases diagnosed in the all-oral DAA period (P < 0.0001). One thousand, three hundred and thirty-seven HIV/HCV-coinfected patients with cirrhosis achieved SVR in the cohort. The frequency of HCC after SVR declined from 15% among those cured with pegylated-IFN with ribavirin to 1.62 and 0.87% among those cured with DAA with and without IFN, respectively. In patients with previous HCC treated with curative therapies, HCC recurrence occurred in two (25%) out of eight patients treated with IFN-based regimens and four (21%) out of 19 treated with DAA-IFN-free regimens (P = 1.0). CONCLUSION: The frequency of HCC emergence after SVR has not increased after widespread use of DAA in HIV/HCV-coinfected patients. DAA do not seem to impact on HCC recurrence in the short-term among those with previously treated HCC. PMID- 29596109 TI - Sexual risk behaviour trajectories among MSM at risk for HIV in Amsterdam, the Netherlands. AB - OBJECTIVE: Sexual risk behaviour changes during a person's life course. Insights in sexual risk behaviour trajectories of MSM may provide starting points for the timing of HIV prevention methods. We aimed to study longitudinal trajectories of sexual risk behaviour predictive of HIV acquisition from sexual debut onwards. DESIGN: A longitudinal study among 815 HIV-negative participants of the Amsterdam Cohort Studies (ACS) who completed extensive questionnaires about their sexual behaviour every 6 months between 2007 and 2017. METHODS: A comprehensive behavioural risk score predictive of HIV seroconversion was developed. On the basis of this risk score, linear trajectories of sexual risk behaviour and MSM group membership were estimated using latent class growth mixture modelling. Associations between longitudinal trajectories and demographic and psychosocial factors were examined. RESULTS: Three trajectories of sexual risk behaviour were identified, which were labelled Low risk (90.3% of the sample), Falling high risk (6.5%) and Rising high risk (3.3%). MSM following the Falling high risk (20.5%) and Rising high risk (25.0%) trajectories were more likely to acquire HIV during follow-up. The Falling high risk trajectory was associated with younger age at sexual debut, fewer steady partnerships and high percentages of substance use. The Rising high-risk trajectory was associated with increasing percentages of substance use over time. CONCLUSION: MSM follow different trajectories of changing sexual risk behaviour over time. Early identification of MSM following a trajectory of falling or rising high-risk behaviour and adequate timing of individual-based preventive interventions may reduce HIV transmission. PMID- 29596110 TI - Cardiac and inflammatory biomarkers in perinatally HIV-infected and HIV-exposed uninfected children. AB - OBJECTIVES: To compare distributions of serum cardiac and inflammatory biomarkers between perinatally HIV-infected (PHIV) and perinatally HIV-exposed uninfected (PHEU) children, to evaluate their associations with echocardiographic measures, and among PHIV youth, with antiretroviral therapy (ART) and HIV disease severity measures. DESIGN: Cross-sectional analysis of temporally paired serum samples for biomarkers and echocardiograms in a prospective multicenter cohort study of PHIV and PHEU youth. METHODS: Serum samples were analyzed among 402 youth in the PHACS Adolescent Master Protocol (AMP) for high-sensitivity cardiac troponin-T (hs cTnT, a cardiomyocyte injury marker), N-terminal-pro-brain natriuretic peptide (NT-proBNP, a myocardial stress marker), and inflammatory markers [high sensitivity C-reactive protein, interleukin (IL)-1, IL-6, IL-8, IL-10, IL-18, tumor necrosis factor-alpha (TNF-alpha), and soluble TNF receptor II (sTNF-RII)]. Echocardiograms were centrally measured and parameters converted to z cores to account for differences in age and body size. RESULTS: Compared with PHEU (N = 156), PHIV youth (N = 246) more often had detectable hs-cTnT and higher levels of sTNF-RII and IL-18. Higher inflammatory biomarkers were generally associated with higher left ventricular (LV) wall stress and lower LV function and LV mass in the two groups. Among PHIV youth, the biomarkers were more strongly associated with current rather than historical immunologic and virologic status. CONCLUSION: PHEU and PHIV have modest, significant differences in serum levels of specific inflammatory and active myocardial injury biomarkers. Higher biomarker levels were associated with lower LV mass and shifts in LV structure. Further study is warranted on the longitudinal role of cardiac and inflammatory biomarkers for targeting interventions among PHIV and PHEU youth. PMID- 29596113 TI - Development and Feasibility of an Interactive Smartphone App for Early Assessment and Management of Symptoms Following Pancreaticoduodenectomy. AB - BACKGROUND: Patients who have undergone pancreaticoduodenectomy because of pancreatic cancer experience distressing symptoms and unmet supportive care needs after discharge. To meet these needs, we have developed a mobile health app (Interaktor) for daily assessment of symptoms and access to self-care advice that includes a risk assessment model for alerts with real-time interactions with professionals. OBJECTIVE: The study aim was to develop and test a version of the Interaktor app adapted for patients who have undergone pancreaticoduodenectomy. METHODS: The app was developed and tested for feasibility in 6 patients during 4 weeks. One nurse monitored and responded to alerts. Logged data from the app were collected, and all participants were interviewed about their experiences. RESULTS: Adherence to reporting daily was 84%. Alerts were generated in 41% of the reports. The patients felt reassured and cared for and received support for symptom management. The app was easy to use, had relevant content, and had few technical problems, although suggestions for improvement were given. CONCLUSIONS: The daily reporting of symptoms and having access to a nurse in real time in the case of an alarming symptom seem to enhance symptom management and render a feeling of security in patients. Some modifications of the app are needed before use in a larger sample. IMPLICATIONS FOR PRACTICE: Daily reporting of symptoms after pancreaticoduodenectomy enhances symptom management, self-care, and participation without being a burden to patients, indicating that mobile health can be used in clinical practice by patients with poor prognosis who experience severe symptoms. PMID- 29596114 TI - ACUTE MACULAR NEURORETINOPATHY IN SUSAC SYNDROME: A NEW ASSOCIATION. AB - PURPOSE: To report a case of acute macular neuroretinopathy in a patient with Susac syndrome. METHODS: Case report. RESULTS: A 39-year-old male patient presented with severe headache, photopsias, and a sudden onset of hearing loss in the right ear. Fluorescein angiography of the right eye revealed multiple branch retinal artery occlusions. Clinical presentation of encephalopathy, hearing loss, and branch retinal artery occlusions, along with characteristic magnetic resonance imaging findings, led to a diagnosis of Susac syndrome. Despite aggressive immunosuppression for four months, the patient later presented with acute macular neuroretinopathy in the left eye. CONCLUSION: Acute macular neuroretinopathy and Susac is a new association of two well-defined disorders. The concurrence of both disorders supports retinal ischemia as the proximate cause of acute macular neuroretinopathy and inflammation as a potential etiology. PMID- 29596112 TI - Vagal dysfunction and small intestinal bacterial overgrowth: novel pathways to chronic inflammation in HIV. AB - OBJECTIVE: Chronic inflammation in HIV-infected individuals drives disease progression and the development of comorbidities, despite viral suppression with combined antiretroviral therapy. Here, we sought evidence that vagal dysfunction, which occurs commonly as part of HIV-associated autonomic neuropathy, could exacerbate inflammation through gastrointestinal dysmotility, small intestinal bacterial overgrowth (SIBO), and alterations in patterns of soluble immune mediators. DESIGN: This is a cross-sectional observational study. METHODS: Forty participants on stable combined antiretroviral therapy with gastrointestinal symptoms, and no causes for vagal or gastrointestinal dysfunction other than HIV, underwent autonomic testing, hydrogen/methane breath testing for SIBO, and gastric emptying scintigraphy. A panel of 41 cytokines, high-mobility group box 1, and markers of bacterial translocation (lipopolysaccharide) and monocyte/macrophage activation (sCD14 and sCD163) were tested in plasma. RESULTS: We found that participants with vagal dysfunction had delayed gastric emptying and higher prevalence of SIBO. SIBO was associated with IL-6, but not sCD14; lipopolysaccharide could not be detected in any participant. We also found alteration of cytokine networks in participants with vagal dysfunction, with stronger and more numerous positive correlations between cytokines. In the vagal dysfunction group, high mobility group box 1 was the only soluble mediator displaying strong negative correlations with other cytokines, especially those cytokines that had numerous other strong positive correlations. CONCLUSION: The current study provides evidence that the vagal component of HIV-associated autonomic neuropathy is associated with changes in immune and gastrointestinal function in individuals with well treated HIV. Further study will be needed to understand whether therapies targeted at enhancing vagal function could be of benefit in HIV. PMID- 29596115 TI - Sensitization of recombinant human tumor necrosis factor-related apoptosis inducing ligand-resistant malignant melanomas by quercetin. AB - Malignant melanoma is the most commonly diagnosed skin cancer associated with a high rate of metastasis. Low-stage melanoma is easily treated, but metastatic malignant melanoma is an extremely treatment-resistant malignancy with low survival rates. The application of recombinant human tumor necrosis factor related apoptosis-inducing ligand (rhTRAIL) for the treatment of metastatic malignant melanoma holds considerable promise because of its selective proapoptotic activity towards cancer cells and not nontransformed cells. Unfortunately, the clinical utilization of rhTRAIL has been terminated due to the resistance of many cancer cells to undergo apoptosis in response to rhTRAIL. However, rhTRAIL-resistance can be abrogated through the cotreatment with compounds derived from 'Mother Nature' such as quercetin that can modulate cellular components responsible for rhTRAIL-resistance. Here, we show that rhTRAIL-resistant malignant melanomas are sensitized by quercetin. Quercetin action is manifested by the upregulation of rhTRAIL-binding receptors DR4 and DR5 on the surface of cancer cells and by increased rate of the proteasome-mediated degradation of the antiapoptotic protein FLIP. Our data provide for a new efficient and nontoxic treatment of malignant melanoma. PMID- 29596117 TI - Multiple Solid Organ Transplantation in Telomeropathy: Case Series and Literature Review. AB - BACKGROUND: Solid organ transplantation is a valid treatment option for selected patients with organ failure due to an underlying telomeropathy; however, the feasibility of multiple-organ transplantation if several organs are compromised is unclear. METHODS: We describe 2 patients with telomeropathy due to heterozygous telomerase RNA component or telomerase reverse transcriptase mutation, who successfully underwent serial or combined liver and lung transplantation for concurrent liver fibrosis/cirrhosis and pulmonary fibrosis. RESULTS: Despite a challenging posttransplant course, long-term outcomes were favorable, with both patients doing fine now, respectively, 12/20 and 24 months after multiple-organ transplantation. CONCLUSIONS: To our knowledge, this is the first report of multiple solid organ transplantation in documented telomeropathy. These cases highlight current difficulties of timely diagnosis, therapeutic approach, and postoperative complications in telomeropathy patients in whom several organs are affected. PMID- 29596116 TI - The Third International Consensus Guidelines on the Management of Cytomegalovirus in Solid-organ Transplantation. AB - Despite recent advances, cytomegalovirus (CMV) infections remain one of the most common complications affecting solid organ transplant recipients, conveying higher risks of complications, graft loss, morbidity, and mortality. Research in the field and development of prior consensus guidelines supported by The Transplantation Society has allowed a more standardized approach to CMV management. An international multidisciplinary panel of experts was convened to expand and revise evidence and expert opinion-based consensus guidelines on CMV management including prevention, treatment, diagnostics, immunology, drug resistance, and pediatric issues. Highlights include advances in molecular and immunologic diagnostics, improved understanding of diagnostic thresholds, optimized methods of prevention, advances in the use of novel antiviral therapies and certain immunosuppressive agents, and more savvy approaches to treatment resistant/refractory disease. The following report summarizes the updated recommendations. PMID- 29596118 TI - Treatment of Depression With Duloxetine in Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-Like Episodes. AB - The mitochondrial cytopathies are a heterogeneous group of diseases characterized by heteroplasmic maternal transmission and selective dysfunction of tissues and organs highly dependent on aerobic respiration (eg, skeletal muscle, cardiac muscle, and brain). Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is a specific subtype of mitochondrial cytopathy that is commonly associated with mood disturbances in individuals who survive until adulthood. Because of the altered cellular metabolism inherent in MELAS, it is often difficult to determine drug dosing, drug choice, and treatment response in patients with this rare disease. Historically, management of these patients focused on symptomatic relief and supplementation of compounds thought to optimize aerobic respiration (specifically, enzyme Co-Q10). We report a case in which an adult patient with MELAS and comorbid major depressive disorder demonstrated excellent response to the selective serotonin-norepinephrine reuptake inhibitor medication duloxetine. PMID- 29596119 TI - Normative Data for the Low Anterior Resection Syndrome Score (LARS Score). AB - OBJECTIVE: To provide normative data for the Low Anterior Resection Syndrome (LARS) score. BACKGROUND: The LARS score is a validated and frequently used tool measuring bowel dysfunction after sphincter sparing surgery for rectal cancer. The interpretation of LARS score results has previously been limited by the lack of normative data. METHODS: An age and sex-stratified random sample of 3440 citizens from the general population was drawn from the Danish civil registration system (age range 20-89 years, 50% females). A brief questionnaire including the LARS score and health-related items were distributed electronically or by post. RESULTS: A total of 1875 (54.5%) responded, 54.0% were females. In the age group 50 to 79 years, relevant for most rectal cancer studies, the response rate was 70.5% (n = 807). In this specific age group, 18.8% of the females and 9.6% of the males had a LARS score >=30, corresponding to the LARS score category "major LARS" (P = 0.001), and the median (interquartile range) LARS score was 16 (7-26) and 11 (4-22), respectively (P < 0.001). Responders with physical disease had a statistically significant higher risk of a LARS score >=30, compared with responders without any physical disease (odds ratio 2.2, 95% confidence interval 1.6-2.9, P < 0.001). CONCLUSIONS: A LARS score >=30 (major LARS) is common in the general population, especially in the age group 50 to 79 years. Normative data for the LARS score are now available and can be taken into account when interpreting LARS score results in scientific studies of bowel function after rectal cancer treatment. PMID- 29596120 TI - Survival in Locally Advanced Pancreatic Cancer After Neoadjuvant Therapy and Surgical Resection. AB - OBJECTIVE: The aim of the study was to identify the survival of patients with locally advanced pancreatic cancer (LAPC) and assess the effect of surgical resection after neoadjuvant therapy on patient outcomes. BACKGROUND: An increasing number of LAPC patients who respond favorably to neoadjuvant therapy undergo surgical resection. The impact of surgery on patient survival is largely unknown. MATERIALS AND METHODS: All LAPC patients who presented to the institutional pancreatic multidisciplinary clinic (PMDC) from January 2013 to September 2017 were included in the study. Demographics and clinical data on neoadjuvant treatment and surgical resection were documented. Primary tumor resection rates after neoadjuvant therapy and overall survival (OS) were the primary study endpoints. RESULTS: A total of 415 LAPC patients were included in the study. Stratification of neoadjuvant therapy in FOLFIRINOX-based, gemcitabine based, and combination of the two, and subsequent outcome comparison did not demonstrate significant differences in OS of 331 non-resected LAPC patients (P = 0.134). Eighty-four patients underwent resection of the primary tumor (20%), after a median duration of 5 months of neoadjuvant therapy. FOLFIRINOX-based therapy and stereotactic body radiation therapy correlated with increased probability of resection (P = 0.006). Resected patients had better performance status, smaller median tumor size (P = 0.029), and lower median CA19-9 values (P < 0.001) at PMDC. Patients who underwent surgical resection had significant higher median OS compared with those who did not (35.3 vs 16.3 mo, P < 0.001). The difference remained significant when non-resected patients were matched for time of neoadjuvant therapy (19.9 mo, P < 0.001). CONCLUSIONS: Surgical resection of LAPC after neoadjuvant therapy is feasible in a highly selected cohort of patients (20%) and is associated with significantly longer median overall survival. PMID- 29596121 TI - FOOD INSECURITY: A PUBLIC HEALTH CHALLENGE. PMID- 29596122 TI - Increasing Hepatitis C Virus Knowledge Through an Evidence-Based Educational Intervention. AB - Hepatitis C virus infection is the most common chronic blood-borne infection in the United States (U.S.). Increasing rates of hepatitis C virus infection among drug users present a significant public health problem in the U.S. and globally. This article describes the effect an educational intervention on hepatitis C virus knowledge. A project was conducted using the Brief Hepatitis C Knowledge Scale to assess pre- and post-test intervention knowledge. An educational intervention consisting of a video (Hepatitis C: Get the Facts) and a written handout, as well as a question-and-answer session, was administered to participants at a local health department. Analysis of the data through use of descriptive statistics to compare percentage change of the mean from the pretest to post-test to 3-week post-test intervention was performed. Results demonstrated the use of an educational intervention to be effective in increasing hepatitis C virus knowledge. An increase in knowledge regarding hepatitis C virus transmission may lead to a decrease in overall hepatitis C virus infection rates as well as risky behaviors. PMID- 29596123 TI - Fast-Track Recovery Program After Major Liver Resection: A Randomized Prospective Study. AB - The objective of this study was to compare fast-track (FT) recovery protocol with the conventional one in patients treated with major liver resection by evaluating perioperative morbidity, length of hospitalization, and readmission rate. Sixty two patients suffering from malignant liver tumors were surgically treated from May 2012 to April 2014. After randomization, they were prospectively divided into two groups: Group A patients (n = 32) followed FT recovery protocol and Group B patients (n = 30) were treated with the conventional (CON) protocol. Postoperative morbidity, readmission rate, and median hospital stay in the two groups were studied. Fast-track protocol was associated with a decreased complication (25%, p = .002), whereas the risk of postoperative morbidity was 2.4 times higher in patients treated with the CON protocol (60%, p = .002). Readmission rate was not significantly different between the two groups (6.25%, p = .35). Age (p = .382) and body mass index (p = .818) were not a suspending factor for following the FT protocol. Overall length of stay (postoperative days) in the FT group was (mean +/- SD) 5.75 +/- .5 and in the CON group was 13.5 +/- 6.7 (p < .001). Fast-track recovery protocol seems to be safe and particularly efficient in patients undergoing major liver resections. PMID- 29596124 TI - Diverticular Disease: Traditional and Evolving Paradigms. AB - Diverticular disease includes diverticulosis, which are sac protrusions of the intestinal mucosa, and diverticulitis, inflammation of the diverticula. Diverticular disease is listed as one of the top 10 leading physician diagnoses for gastrointestinal disorders in outpatient clinic visits in the United States. There are several classifications of diverticular disease ranging from asymptomatic diverticulosis to diverticulitis with complications. Several theories are linked to the development of diverticula which includes the physiology of the colon itself, collagen cross-linking, and recently challenged, low-fiber intake. The differential diagnoses of lower abdominal pain in addition to diverticular disease have overlapping signs and symptoms, which can make a diagnosis challenging. Identification of the distinct signs and symptoms of each classification will assist the practitioner in making the correct diagnosis and lead to appropriate management. The findings from recent studies have changed the paradigm of diverticular disease. The purpose of this article is to discuss traditional dogma and evolving concepts in the pathophysiology, prevention, and management of diverticular disease. Practitioners must be knowledgeable about diverticular disease for improved outcomes. PMID- 29596125 TI - Diverticular Disease: Traditional and Evolving Paradigms. PMID- 29596126 TI - Factors Influencing the Life Experiences of Individuals With Inflammatory Bowel Disease. AB - Inflammatory bowel disease has a negative impact on individuals perception of their health status and is associated with disabling processes that have physical, social, and work repercussions. The objectives of this study were to describe the life experiences of individuals with Crohn disease and ulcerative colitis and to develop a theoretical framework to describe the relationships of these diseases with personal and clinical factors. A qualitative study on the basis of grounded theory was conducted, involving individual and semistructured interviews on the life experiences of 14 adults of different ages with inflammatory bowel disease in relapse or inactive phase. The individuals in relapse phase and those with a short time since diagnosis had the most negative perceptions of their health, and experienced impaired ability for daily activities. The life experiences of individuals with inflammatory bowel disease were influenced by the time since diagnosis and the disease phase, with no gender difference in either factor. The predominant strategy of participants for coping with the disease was to pursue normality. According to these findings, nursing interventions should focus on the initial adaptation phase and on coping strategies during active phases of the disease. PMID- 29596127 TI - Effect of Early Postoperative Feeding on the Recovery of Children Post Appendectomy. AB - The aim of this study was to determine the effect of early postoperative feeding on recovery after appendectomy in children. It was undertaken as a multicenter study. Patients were randomly assigned to 2 groups, each containing 46 children. Postoperatively, liquid and solid food intake and evacuation of first flatus and stool were recorded for the intervention and routine care groups. Postoperative thirst, hunger, nausea, and pain levels were evaluated at regular intervals using the Visual Analogue Scale. Data were obtained as number, mean, and percentage, and statistically analyzed using the chi-square test and the 2-sample t test. A statistically significant difference was found for both the first evacuation of flatus and stool and the length of hospital stay. Patients in the intervention group had evacuated flatus and stool earlier and had a shorter hospital stay than the control group. In addition, a significant difference was found in hunger (48th hour), thirst (36th and 48th hours), and pain (48th hour) levels between the intervention and control groups. Early postoperative feeding in children who have had an appendectomy affects the occurrence of the first evacuation of flatus and stool, the length of hospital stay, and the level of hunger, thirst, and pain. PMID- 29596128 TI - A Retrospective Study Comparing Polyethylene Glycol-Electrolyte Solution With Magnesium Citrate for Treatment of Fecal Disimpaction. AB - Fecal disimpaction in the hospital setting may be necessary for a constipated child's condition to improve. This study evaluated the efficiency of 2 disimpaction therapies: nasogastric GoLYTELY (polyethylene glycol-electrolyte solution) compared with oral magnesium citrate. Retrospective chart review of 103 children was conducted to determine the time from the start of the clinic cleanout until abdominal radiograph verification of successful stool evacuation. The children were in an age range of 1-18 years, with average age of 8 years. Forty-five were female and 59 were male. Forty-six (45%) children received nasogastric polyethylene glycol-electrolyte and 57 (55%) drank magnesium citrate. The children receiving nasogastric polyethylene glycol-electrolyte on average required 2.5 enemas, and the children receiving magnesium citrate required 3.0 enemas. The average time for a nasogastric polyethylene glycol-electrolyte cleanout was 5 hours 15 minutes (range: 3 hours 30 minutes to 7 hours) and 5 hours 30 minutes for magnesium citrate cleanout (range: 2 to 8 hours). Seven (15%) children who received nasogastric polyethylene glycol-electrolyte and 6 (10%) of those who drank magnesium citrate did not achieve clearance of stool on the second radiograph. Vomiting was an adverse effect of both medications, and 7 (12%) children were unable to drink the entire magnesium citrate dose. Both methods of disimpaction take the same amount of time. Magnesium citrate can be difficult to drink; however, it is less invasive and less costly than nasogastric polyethylene glycol-electrolyte. PMID- 29596129 TI - Healthcare Transition in Pediatrics and Young Adults With Inflammatory Bowel Disease: A Scoping Review. AB - The incidence of inflammatory bowel disease has steadily increased in children within the last decade. As young adults transition into the adult healthcare system, lack of support can lead to disease exacerbations and disease-related complications. The purpose of this scoping review was to examine the current healthcare transition literature in pediatrics and young adults with inflammatory bowel disease, with a particular focus on assessment or screening tools to evaluate healthcare transition readiness. Five most relevant databases were searched. Of these, 22 articles met the inclusion criteria and key findings from these are summarized. The majority of articles focused on adolescents or young adults with inflammatory bowel disease and were primarily published in the United States. Since 2008, there has been a growing trend in publications of inflammatory bowel disease healthcare transition literature. Articles were often described as healthcare transition readiness assessment tools, patient outcomes following transition, or transition experiences and barriers. An understanding of the current literature on the readiness assessment and support strategies is required to promote an improved quality of life for pediatric and young adult patients living with inflammatory bowel disease. PMID- 29596130 TI - Screening Indication Associated With Lower Likelihood of Minor Adverse Events in Patients Undergoing Outpatient Colonoscopy. AB - We sought to determine, among outpatients at one university hospital endoscopy center, rates of self-reported minor adverse events (MAEs) at 2, 14, and 30 days postcolonoscopy and to identify predictors of MAEs at Day 2 postcolonoscopy. A single-center longitudinal cohort study with follow-ups at Days 2, 14, and 30 postcolonoscopy was conducted in Montreal, Canada. Baseline self-report data included patient age, gender, gastrointestinal discomforts and other discomforts in the preceding month, and comorbidity. Intracolonoscopy procedures and the method of insufflation were obtained from endoscopy reports. Minor adverse event data were obtained by either phone or Internet survey. Multivariate logistic regression was used to identify predictors of MAEs at Day 2. Of 705 individuals approached, 420 (mean age = 58.7 years; SD = 8.4, 45.7% female) were eligible and consented to study participation, and 378 (90%) participated in at least one follow-up. At Days 2, 14, and 30, 86 (25.1%), 46 (13.7%), and 13 (3.1%) patients, respectively, experienced at least one MAE. At the Day 30 follow-up, 2 (0.53%) patients reported having experienced a serious adverse event. The multivariable analysis results showed that screening compared with nonscreening colonoscopy was protective for MAEs at 2 days (OR = 0.5, 95% CI [0.3, 0.9]). We found that 25% of patients experienced at least one MAE at 2 days postcolonoscopy, and screening compared with nonscreening colonoscopy patients were half as likely to experience these early MAEs. Nurses may use these findings to educate and reassure patients about colonoscopy risks. Large, longitudinal multicenter studies are needed to corroborate our findings.

AB - BACKGROUND: Most clinical measurements of radioactivity, whether for therapeutic or imaging nuclides, rely on commercial re-entrant ionization chambers ('dose calibrators'). The National Institute of Standards and Technology (NIST) maintains a battery of representative calibrators and works to link calibration settings ('dial settings') to primary radioactivity standards. Here, we provide a summary of NIST-determined dial settings for 22 radionuclides. METHODS: We collected previously published dial settings and determined some new ones using either the calibration curve method or the dialing-in approach. RESULTS: The dial settings with their uncertainties are collected in a comprehensive table. CONCLUSION: In general, current manufacturer-provided calibration settings give activities that agree with National Institute of Standards and Technology standards to within a few percent. PMID- 29596135 TI - We want to hear about you!: 2018 Richard Hader Visionary Leader Award. PMID- 29596134 TI - Assessing Resident Safety Culture in Six Nursing Homes in Belgium. AB - OBJECTIVES: The primary aim was to measure resident safety culture in six nursing homes in northern Belgium (Flanders). In addition, differences in safety culture perceptions between professions were also examined. Finally, results of the present study were compared with the Nursing Home Comparative Database from the Agency for Healthcare Research and Quality (USA). METHODS: A cross-sectional study was conducted by administering the Nursing Home Survey on Patient Safety Culture in six nursing homes in Belgium (Flanders). Each nursing home has 92 to 170 licensed nursing home beds. Data collection occurred between December 2016 and January 2017. RESULTS: Highest mean scores were found for "feedback and communication about incidents" (mean [SD] = 4.20 [0.58]), "overall perceptions of resident safety" (mean [SD] = 4.07 [0.52]), and "supervisor expectations and actions promoting resident safety" (mean [SD] = 4.04 [0.70]). The lowest mean score was found for "staffing" (mean [SD] = 2.99 [0.61]). In addition, managers/supervisors scored significantly higher on all resident safety dimensions, with the exception of the dimensions "teamwork" and "supervisor expectations and actions promoting resident safety." Finally, the present study scored higher on the dimensions "teamwork," "nonpunitive response to mistakes," "handoffs," "feedback and communication about incidents," and "communication openness" than the benchmarking data from the Nursing Home Comparative Database. CONCLUSIONS: More work is necessary to improve the safety of resident care in nursing homes, especially regarding staffing issues and turnover rates. The present research findings serve to shine a light on an often-overlooked patient population and emphasize the need to develop improvement strategies for preventing resident safety incidents in nursing homes.

AB - BACKGROUND: Obesity and depression are common comorbid conditions. The objective of the study was to evaluate the effect of obesity on the pharmacokinetics of the serotonergic antidepressant vortioxetine. METHODS: Vortioxetine pharmacokinetics were evaluated in 16 otherwise healthy obese volunteers (mean weight, 119 kg; mean body mass index (BMI) 41.8 kg/m) and in 14 normal-weight subjects (mean weight, 68 kg; mean BMI, 23.0 kg/m) matched for age. All subjects received a single 5-mg oral dose of vortioxetine once daily for 29 days. Pre-dose plasma vortioxetine concentrations were measured during the 29 days of dosing, and during a 4-week washout period after the last dose. Full 24-hour profiles were obtained after the first and last doses. RESULTS: Vortioxetine accumulated extensively over the 29 days; the accumulation ratio was not significantly different between obese and control groups (means: 5.24 and 4.46, respectively). Steady-state concentration (Css) and steady-state clearance also did not differ between groups. However mean washout half-life (T1/2) was significantly prolonged in obese vs. control subjects (3.26 days vs. 2.21 days, P < 0.01). Up to 89% of the individual variability in T1/2 was explained by the product of Css and numeric indicators of the degree of obesity. CONCLUSIONS: The half-life of vortioxetine washout after discontinuation of therapy is significantly prolonged in obese individuals compared to normal weight controls. To avoid a potential risk of serotonin syndrome, obese patients who plan to change their medication from vortioxetine to a monoamine oxidase inhibitor (MAOI) should extend the time between vortioxetine discontinuation and MAOI initiation beyond what is recommended in the product label. PMID- 29596147 TI - Maternal Antidepressant Use During Pregnancy and the Risk of Attention Deficit/Hyperactivity Disorder in Children: A Systematic Review of the Current Literature. AB - PURPOSE: This study reviewed the current literature examining the potential relationship between use of antidepressants during pregnancy and attention deficit/hyperactivity disorder (ADHD) in children. METHODS: PubMed was searched for English language reports between January 1, 1995, and July 31, 2017, by using combinations of the key words pregnancy, antidepressants, selective serotonin reuptake inhibitors (SSRIs), selective serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), children, offspring, and ADHD. Studies that reported association between ADHD in children and use of antidepressant in pregnant women were included in the review. RESULTS: A total of 7 relevant studies that met the review criteria were examined. The studies reported that compared with nonusers adjusted risks of ADHD in children were 1.2 to 1.6 for the use of any antidepressant, 0.91 to 1.66 for selective serotonin reuptake inhibitors, 1.1 to 1.4 for selective serotonin-norepinephrine reuptake inhibitors, and 1.1 to 1.8 for tricyclic antidepressants. There was some scientific evidences suggesting a connection between antidepressant use during all trimesters of pregnancy and increased risk of ADHD in children. In addition, the study results suggest that underlying maternal anxiety or depressive disorders may also contribute to increased risk of ADHD. IMPLICATIONS: Although some studies have suggested a moderately increased risk of ADHD in children with maternal antidepressant use during pregnancy, based on limitations and results of the studies, this review concluded that there is no strong evidence to suggest a causal link.

PMID- 29596148 TI - Personalized (N-of-1) Trials for Depression: A Systematic Review. AB - PURPOSE/BACKGROUND: Personalized (N-of-1) trials are single-patient, crossover design trials that may be useful for personalizing the selection of depression treatments. We conducted a systematic review of published N-of-1 trials for depression to determine the feasibility and suitability of this methodology for personalizing depression care. METHODS/PROCEDURES: Electronic databases were searched from database inception through October 2016. Studies were selected if they enrolled depressed patients, included a within-subject crossover design, and systematically assessed depressive symptoms during the N-of-1 trial. FINDINGS/RESULTS: Five eligible studies reporting on 47 depressed patients (range, 1-18 patients) were identified. Two studies were conducted among adults with treatment-resistant depression, 1 study among depressed inpatients, and 2 studies among patients from special populations (geriatric nursing home, human immunodeficiency virus-associated encephalopathy). All studies evaluated the effects of pharmacologic treatments (methylphenidate, D-amphetamine, ketamine, and sulpiride). Three studies compared an off-label treatment with placebo, 1 study compared 2 off-label treatments, and 1 study compared escalating doses of an off-label treatment with placebo. All 4 studies with more than 1 participant demonstrated heterogeneous treatment effects. All studies produced data that could personalize treatment selection for individual patients. No studies reported on recruitment challenges, compliance with self-tracking, or satisfaction with participation. IMPLICATIONS/CONCLUSIONS: The feasibility of N of-1 trials for depression was demonstrated for a limited number of second-line pharmacologic treatments in treatment-resistant patients or in patients with comorbidities that would have excluded them from conventional randomized controlled trials. Additional research is needed to determine whether N-of-1 trials are suitable for improving the selection of depression treatments in clinical practice. PMID- 29596150 TI - Effects of Intranasal Oxytocin Administration on Sexual Functions in Healthy Women: A Laboratory Paradigm. AB - PURPOSE: The neuropeptide oxytocin (OXT) has a variety of physiological functions in maternal behavior and attachment including sexual behavior. Based on animal research and our previous human studies, we set out to investigate intranasal administration of OXT and hypothesized that OXT should be able to modulate sexual function in women. METHODS: In a double-blind, placebo-controlled, crossover laboratory setting, the acute effects of intranasal administered OXT (24 international units) on sexual drive, arousal, orgasm, and refractory aspects of sexual behavior were analyzed in 27 healthy females (mean age +/- SD, 27.52 +/- 8.04) together with physiological parameters using vaginal photoplethysmography. FINDINGS: Oxytocin administration showed no effect on subjective sexual parameters (eg, postorgasmic tension; P = 0.051). Physiological parameters (vaginal photoplethysmography amplitude and vaginal blood volume) showed a response pattern towards sexual arousal but were not affected by OXT. IMPLICATIONS: Using a well-established laboratory paradigm, we did not find that intranasal OXT influences female sexual parameters. Also, sexual drive and other functions were not affected by OXT. These findings indicate that OXT is not able to significantly increase subjective and objective parameters of sexual function in a setting with high internal validity; however, this might be different in a more naturalistic setting.

AB - Status epilepticus (SE) can result in an overproduction of hydrogen peroxide (H2O2), which contributes to oxidative stress and brain injury during different phases of epileptogenesis and seizures. In this study, we measured the extracellular H2O2 concentration in the rat hippocampus in a temporal lobe epilepsy model. A new fluorescent technique for measuring H2O2 in vivo simultaneously with electroencephalography recording was tested. The method consists of mixing microdialysate with an enzymatic reactor to produce a fluorescent compound. The fluorescence intensity was measured every second and was proportional to the H2O2 concentration. The results showed that H2O2 was released during SE; we detected a significant increase of up to five times over the baseline value that correlated with changes in electrical activity. We also observed that H2O2 was produced for days after SE and was associated with continuous neuronal death and seizure generation. Therefore, we monitored H2O2 48 h and 15 days after SE, observing increases of up to 96 and 124%, respectively, accompanied by changes in electrical activity with spontaneous discharges of large amplitude. These changes may reflect the oxidative stress generated during epileptogenesis that remains during the chronic period (458% increased) with the presence of large spikes, indicating that the H2O2 could also participate in the generation and maintenance of spontaneous recurrent seizures. There are no previous reports on the detection of H2O2 at this temporal resolution; thus, this study contributes a novel technique for studying and understanding epileptogenesis to develop new antioxidant strategies for the treatment of temporal lobe epilepsy.

AB - Drug dependence and withdrawal syndrome induced by abrupt cessation of opioid administration remain a severe obstacle in the clinical treatment of chronic pain and opioid drug addiction. One of the key symptoms during opioid withdrawal is hyperalgesia. The mechanism of opioid withdrawal-induced hyperalgesia remains unclear. P2X2 and P2X3 receptors, members of P2X receptor subunits, act as the integrator of multiple forms of noxious stimuli and play an important role in nociception transduction of chronic neuropathic and inflammatory pain. The process of P2X2 and P2X3 receptor antagonism inhibits inflammatory hyperalgesia, involving the spinal opioid system. However, the role of P2X receptors involved in opioid withdrawal-induced hyperalgesia has seldom been discussed. To explore the role of P2X2 and P2X3 receptors in the opioid-induced hyperalgesia, heroin self-administration rats were adopted, and the thermal and mechanical nociceptive thresholds were evaluated using the paw withdrawal test after abstinence from heroin for 8 days. In addition, the expressions of P2X2 and P2X3 receptors in dorsal root ganglia were analyzed by immunofluorescence. The results showed that after 8 days of abstinence, heroin self-administration rats showed thermal hyperalgesia and mechanical allodynia. Meanwhile, the expressions of the P2X2 and P2X3 receptors in dorsal root ganglia were increased. These results suggest that upregulation of P2X2 and P2X3 receptors might partially play a role in heroin withdrawal-induced hyperalgesia. PMID- 29596153 TI - The neural underpinnings of music listening under different attention conditions. AB - Most studies examining the neural underpinnings of music listening have no specific instruction on how to process the presented musical pieces. In this study, we explicitly manipulated the participants' focus of attention while they listened to the musical pieces. We used an ecologically valid experimental setting by presenting the musical stimuli simultaneously with naturalistic film sequences. In one condition, the participants were instructed to focus their attention on the musical piece (attentive listening), whereas in the second condition, the participants directed their attention to the film sequence (passive listening). We used two instrumental musical pieces: an electronic pop song, which was a major hit at the time of testing, and a classical musical piece. During music presentation, we measured electroencephalographic oscillations and responses from the autonomic nervous system (heart rate and high frequency heart rate variability). During passive listening to the pop song, we found strong event-related synchronizations in all analyzed frequency bands (theta, lower alpha, upper alpha, lower beta, and upper beta). The neurophysiological responses during attentive listening to the pop song were similar to those of the classical musical piece during both listening conditions. Thus, the focus of attention had a strong influence on the neurophysiological responses to the pop song, but not on the responses to the classical musical piece. The electroencephalographic responses during passive listening to the pop song are interpreted as a neurophysiological and psychological state typically observed when the participants are 'drawn into the music'. PMID- 29596154 TI - Altered intrinsic activity and functional connectivity in two animal models with opposing fear memories. AB - Post-traumatic stress disorder and sepsis-associated encephalopathy are two common neuropsychiatric disorders, but to some extent with opposing cognitive performance. However, the neural mechanisms underlying these two different phenomena remain poorly understood. In our study, the amplitude of low-frequency fluctuations (ALFF) of spontaneous blood oxygen level-dependent signals was used to assess regional disturbances in two animal models with opposing cognitive performance, namely post-traumatic stress disorder and sepsis-associated encephalopathy. Then, we examined whether the memory-relevant brain regions with impaired ALFF altered functional connectivity within the whole brain. Here, we showed that lipopolysaccharide challenge and footshock induced significantly different cognitive performance. We found significant group differences in ALFF in the bilateral dentate gyrus. In addition, our study showed that footshocks induced a significant decrease in functional connectivity between the left dentate gyrus and the visual cortex compared with the lipopolysaccharide group. Notably, cognitive performance was associated with ALFF values in the right dentate gyrus. In conclusion, our data suggested that damaged regional spontaneous activity and abnormal functional connectivity might be differently involved in two opposing fear memories. PMID- 29596155 TI - miR-221 alleviates the inflammatory response and cell apoptosis of neuronal cell through targeting TNFAIP2 in spinal cord ischemia-reperfusion. AB - This study aimed to examine the role of miR-221 in inflammatory response and apoptosis of neuronal cells after spinal cord ischemia/reperfusion (I/R) injury. Blood samples were obtained from 20 I/R patients and that of 20 healthy individuals were used as a control. AGE1.HN and SY-SH-5Y neuronal cell lines subjected to oxygen-glucose deprivation (OGD) stress were used in cell experiments. Real-time PCR and western blot were used to evaluate the expression of miR-221, tumor necrosis factor-alpha, and TNFAIP2. TUNEL assay analyzed cell apoptosis. I/R patients had lower serum levels of miR-221 than healthy controls. In OGD-AGE1.HN and SY-SH-5Y cells, miR-221 was significantly downregulated and TNFAIP2 mRNA and protein were upregulated; meanwhile, both proinflammatory cytokine tumor necrosis factor-alpha and anti-inflammation cytokine interleukin-6 were elevated and the percentage of apoptotic cells was increased. This inflammatory response and cell apoptosis induced by OGD stress were attenuated by miR-221 overexpression and enhanced by miR-221 knockdown. TNFAIP2 is a target gene for miR-221 and could be regulated negatively by the miR-221 mimic or the miR-221 inhibitor with or without OGD stress. Accordingly, TNFAIP2 overexpression reversed the inflammatory response and cell apoptosis induced by miR-221 under OGD stress. Downregulation of miR-221 occurs in spinal cord I/R injury and in cell lines subjected to oxygen-glucose deprivation. miR-221 regulates the inflammatory response and apoptosis of neuronal cells through its impact on TNFAIP2. PMID- 29596156 TI - Face-sensitive P1 and N170 components are related to the perception of two dimensional and three-dimensional objects. AB - Studies investigating event-related potentials have reported on face-sensitive P1 and N170 components, as well as object-related N170 components. Face-sensitive N170 is also sensitive to face inversion, which has been defined as the face inversion effect. This study aimed to directly compare the relationship between face-sensitive N170 during face perception (upright and inverted faces) and object-related N170 during object perception (two-dimensional and three dimensional objects). More specifically, the purpose was to clarify whether face sensitive P1 and N170 components are related to the perception of two-dimensional and three-dimensional objects. Electroencephalography was performed in participants who were shown one of the four types of stimuli: upright faces, inverted faces, two-dimensional objects, or three-dimensional objects. The results revealed that the latency of P1 for three-dimensional objects was significantly longer than that for two-dimensional objects, the latency of N170 for three-dimensional objects was significantly longer than that for two dimensional objects, and the latency of N170 for inverted faces was significantly longer than that for upright faces. These findings suggest that face-sensitive P1 and N170 components are related to the perception of two-dimensional and three dimensional objects. Moreover, the results suggest that, similar to the face inversion effect of face-sensitive N170 affected by mental rotation of the face, the object-related N170 of three-dimensional objects was affected by the mental rotation of two-dimensional objects. This suggests the novel possibility that face-sensitive P1 and N170 components can be used as an index for the perception of two-dimensional and three-dimensional objects. PMID- 29596157 TI - Machine-learned analysis of the association of next-generation sequencing-based human TRPV1 and TRPA1 genotypes with the sensitivity to heat stimuli and topically applied capsaicin. AB - Heat pain and its modulation by capsaicin varies among subjects in experimental and clinical settings. A plausible cause is a genetic component, of which TRPV1 ion channels, by their response to both heat and capsaicin, are primary candidates. However, TRPA1 channels can heterodimerize with TRPV1 channels and carry genetic variants reported to modulate heat pain sensitivity. To address the role of these candidate genes in capsaicin-induced hypersensitization to heat, pain thresholds acquired before and after topical application of capsaicin and TRPA1/TRPV1 exomic sequences derived by next-generation sequencing were assessed in n = 75 healthy volunteers and the genetic information comprised 278 loci. Gaussian mixture modeling indicated 2 phenotype groups with high or low capsaicin induced hypersensitization to heat. Unsupervised machine learning implemented as swarm-based clustering hinted at differences in the genetic pattern between these phenotype groups. Several methods of supervised machine learning implemented as random forests, adaptive boosting, k-nearest neighbors, naive Bayes, support vector machines, and for comparison, binary logistic regression predicted the phenotype group association consistently better when based on the observed genotypes than when using a random permutation of the exomic sequences. Of note, TRPA1 variants were more important for correct phenotype group association than TRPV1 variants. This indicates a role of the TRPA1 and TRPV1 next-generation sequencing-based genetic pattern in the modulation of the individual response to heat-related pain phenotypes. When considering earlier evidence that topical capsaicin can induce neuropathy-like quantitative sensory testing patterns in healthy subjects, implications for future analgesic treatments with transient receptor potential inhibitors arise. PMID- 29596159 TI - Associations between onset of effort-reward imbalance at work and onset of musculoskeletal pain: analyzing observational longitudinal data as pseudo-trials. AB - Existing evidence of an association between effort-reward imbalance (ERI) at work and musculoskeletal pain is limited, preventing reliable conclusions about the magnitude and direction of the relation. In a large longitudinal study, we examined whether the onset of ERI is associated with subsequent onset of musculoskeletal pain among those free of pain at baseline, and vice versa, whether onset of pain leads to onset of ERI. Data were from the Swedish Longitudinal Occupational Survey of Health (SLOSH) study. We used responses from 3 consecutive study phases to examine whether exposure onset between the first and second phases predicts onset of the outcome in the third phase (N = 4079). Effort-reward imbalance was assessed with a short form of the ERI model. Having neck-shoulder and low back pain affecting life to some degree in the past 3 months was also assessed in all study phases. As covariates, we included age, sex, marital status, occupational status, and physically strenuous work. In the adjusted models, onset of ERI was associated with onset of neck-shoulder pain (relative risk [RR] 1.51, 95% confidence interval [CI] 1.21-1.89) and low back pain (RR 1.21, 95% CI 0.97-1.50). The opposite was also observed, as onset of neck-shoulder pain increased the risk of subsequent onset of ERI (RR 1.36, 95% CI 1.05-1.74). Our findings suggest that when accounting for the temporal order, the associations between ERI and musculoskeletal pain that affects life are bidirectional, implying that interventions to both ERI and pain may be worthwhile to prevent a vicious cycle. PMID- 29596158 TI - Spinal manipulation and exercise for low back pain in adolescents: a randomized trial. AB - Low back pain (LBP) is common in adolescence, but there is a paucity of high quality research to inform care. We conducted a multicenter randomized trial comparing 12 weeks of spinal manipulative therapy (SMT) combined with exercise therapy (ET) to ET alone. Participants were 185 adolescents aged 12 to 18 years with chronic LBP. The primary outcome was LBP severity at 12, 26, and 52 weeks. Secondary outcomes included disability, quality of life, medication use, patient- and caregiver-rated improvement, and satisfaction. Outcomes were analyzed using longitudinal linear mixed effect models. An omnibus test assessing differences in individual outcomes over the entire year controlled for multiplicity. Of the 185 enrolled patients, 179 (97%) provided data at 12 weeks and 174 (94%) at 26 and 52 weeks. Adding SMT to ET resulted in a larger reduction in LBP severity over the course of 1 year (P = 0.007). The group difference in LBP severity (0-10 scale) was small at the end of treatment (mean difference = 0.5; P = 0.08) but was larger at weeks 26 (mean difference = 1.1; P = 0.001) and 52 (mean difference = 0.8; P = 0.009). At 26 weeks, SMT with ET performed better than ET alone for disability (P = 0.04) and improvement (P = 0.02). The SMT with ET group reported significantly greater satisfaction with care at all time points (P <= 0.02). There were no serious treatment-related adverse events. For adolescents with chronic LBP, spinal manipulation combined with exercise was more effective than exercise alone over a 1-year period, with the largest differences occurring at 6 months. These findings warrant replication and evaluation of cost effectiveness. PMID- 29596160 TI - Introduction. PMID- 29596161 TI - Chapter 1. The Historical Roots of Paediatric Gastroenterology, Hepatology, and Nutrition. AB - The last 50 years have seen the establishment of paediatric gastroenterology, hepatology, and nutrition (PGHAN) as a well-recognised and thriving clinical specialty throughout most of Europe, and further afield. This has happened, in part, through the existence of the European Society for Paediatric Gastroenterology and Nutrition (ESPGHAN) as a forum for those interested in this branch of children's medicine. To illustrate the pan-European roots of PGHAN, some key scientific and medical events, discoveries, and inventions relevant to 3 common clinical problems-diarrhoea, jaundice, and infant-feeding-have been chosen to survey the historical development of the ways in which each was understood and treated within the changing thinking and practice of past times. Together they are used to trace the prehistory of ESPGHAN and provide a background against which to explain the genesis of the Society and how its spheres of clinical and scientific interest came to be defined. PMID- 29596162 TI - Chapter 2. ESPGHAN: 50 Years Memories-The Early Years. AB - Thirty-six founding members from Europe were present in 1968, when the European Society of Paediatric Gastroenterology (ESGA) had its first meeting in Paris. The aim was to create a forum for presentations and discussions of research activities in paediatric gastroenterology in Europe. At the second meeting of ESGA 1969 in Interlaken, an important landmark was set for all gastroenterologists in the world. In this conference, the first ever criteria for "the Diagnosis of Coeliac Disease" (CD) were established. In 1990, the revised criteria for the diagnosis of CD were published. After the introduction of new noninvasive techniques, like tissue transglutaminase 2-antibodies and the HLADQ2/HLADQ8 determinations in blood, "new" criteria for the diagnosis of CD were published in 2012 by the European society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Close collaboration of ESPGHAN and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition led to mutual meetings. The first combined meeting was 1978 in Paris, followed by meetings in New York, Amsterdam, Houston, and last in Toulouse. The first World Congress of Paediatric Gastroenterology took place in Boston 2000 followed by congresses in Paris, Iguazu, Taipeh, and Toronto. The creation of specialised committees (Nutrition Committees, GI-Committee, and Hepatology-Committee) enabled the society to elaborate numerous guidelines for standards in the diagnosis and treatment of diseases within the subspecialties. The Journal of Paediatric Gastroenterology and Nutrition, as organ of ESPGHAN and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition since 1991, serves as the voice for these worldwide accepted guidelines. Growing educational activities with summer schools, the Young Investigator Forum and the creation of working groups have distributed our current knowledge among the younger generation and led to fruitful reports, guidelines, and syllabus. In 1992, ESPGHAN was 1 of the founding 7 members of the United European Gastroenterology Federation (UEGF), which developed into a successful organisation for gastroenterology in Europe. This year we celebrate the 50th anniversary of ESPGHAN at our annual Meeting in Geneva. PMID- 29596163 TI - Chapter 3. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition in Recent Years. AB - The European Society for Paediatric Gastroenterology, Hepatology and Nutrition has experienced an amazing development in the 50 years of its existence. It grew from a small group of 36 friends who held an informal meeting with some 20 oral presentations to share and discuss their clinical and research work, to a large, multiprofessional society that sets widely recognized standards for clinical care and policy and hosts the world's largest congress of Paediatric Gastroenterology, Hepatology and Nutrition with more than 4500 delegates from 100 countries. However, the Society's mission has remained the same: to promote the health of children with special attention to the gastrointestinal tract, liver, and nutritional status, through knowledge creation, the dissemination of science based information, the promotion of best practice in the delivery of care and the provision of high-quality education. The European Society for Paediatric Gastroenterology Hepatology and Nutrition's success is based on the enthusiasm and engagement of its membership that contribute extensive volunteer work to support child health, while maintaining a positive spirit of collaboration and friendship, which characterises this Society. This article aims at describing recent developments and the current situation of the European Society for Paediatric Gastroenterology Hepatology and Nutrition. PMID- 29596164 TI - Chapter 4. The Relationship Between the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. AB - This chapter is based on the memories of those who shaped the relationship between the European and the North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. The first joint meeting of the 2 Societies took place in Paris in 1978, followed by 1 in New York in 1985, 1 in Amsterdam in 1990, 1 in Houston in 1994, and the last one in Toulouse in 1998. The formation of the Federation of the International Societies for Pediatric Gastroenterology, Hepatology and Nutrition (FISPGHAN) preceded the First World Congress of all Societies, which took place in Boston in 2000. The success of this meeting was followed by world congresses in Paris in 2004, Iguassu in 2008, Taiwan in 2012, and Montreal in 2016. NASPGHAN and ESPGHAN jointly took on the direction of the Journal of Pediatric Gastroenterology and Nutrition in 1991. Communication between the 2 Societies is extremely active, with members participating in many joint projects. PMID- 29596166 TI - Chapter 5.0. 50 Years of Paediatric Gastroenterology.

ESPGHAN's Contributions to Paediatric Hepatology. PMID- 29596181 TI - Chapter 6.0. History of Paediatric Hepatology in ESPGHAN. AB - Hepatology played an important role in ESPGAN from the beginning. In 1989, the Hepatology Committee was started. In the early 1990s H for hepatology was included in ESPGHAN. Hepatology Summer schools were held from 1995 and later monothematic conferences met the needs of many young ESPGHAN members. The role of ESPGHAN members in the progress of diagnostic and therapeutic measures in hepatitis B and C will be elucidated (Chapter 6.1) as well as the role of other ESPGHAN members in the understanding of immunological hepatic disorders of childhood (Chapter 6.2). During childhood, many metabolic hepatic disorders threaten the life and health of children making orchestrated measures in diagnostic and therapeutic efforts necessary (Chapter 6.3). The pathophysiology of cholestasis was cleared by the detection of bile salt transporters, which were identified by ESPGHAN members in the Netherlands, France, United Kingdom and Germany (Chapter 6.4). Finally liver transplantation for acute fulminant and chronic end stage liver disease was established as a meanwhile standard treatment option (Chapter 6.5). Immunosupression in liver transplantation was improved and standardized through the cooperation of many ESPGHAN member driven studies (Chapter 6.6). PMID- 29596182 TI - Chapter 6.1. Pediatric Chronic Hepatitis B and C: 30 Years of ESPGHAN Clinical Research and Recommendations. AB - The expression of hepatitis B and C virus infections in children differs from that in adults and requires specific paediatric expertise. The European Society of Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) has been a pioneer in this field, having stressed the need for straightforward recommendations since the mid-1980s. Following much observation, surveillance, and research, a panel of ESPGHAN experts was able to develop such recommendations on hepatitis B infection in children in 2009, which was then followed in June 2013 by proper guidelines. In the field of Chronic Hepatitis C, in 2011 ESPGHAN experts published also the Guidance for Clinical Trials for Children and Adolescents, and approved in 2012 the NASPGHAN guidelines for treatment. The ESPGHAN Society is to be commended for its pioneering work in furthering our understanding of chronic hepatitis B and C disease presentations in infants, children, and adolescents.

The Contributions of the ESPGHAN Committees on Nutrition to Paediatric Nutrition. AB - The first Committee on Nutrition (CoN) was founded in 1974. Two years later nutrition (N) was added to the society's name, which then became ESPGAN. The Committee systematised compositional and quality criteria for breast milk substitutes and food for special medical purposes, the first of many examples on how recommendations and comments published by the Committees on Nutrition (CsoN) were adopted by the European Economic Community, later the European Union and also influenced the World Health Organization/Food and Agriculture Organization of the United Nations Codex standards. A second CoN focusing on preterm infants was established in 1979 and its recommendations on nutrition of these infants were widely implemented. The third and standing CoN, established 1986, started to organise high-quality symposia at the annual meetings appreciating the need to enhance the expertise in nutritional research. From 1991 the CoN has organised Summer Schools in paediatric nutrition for young colleagues further emphasising its educational interest and more recently an annual, more specialised Nutrition Masterclass. Successively the interest of the CoN has expanded to other areas, such as highlighting dilemmas and uncertainties in the field of nutrition including the design, choice of outcomes and statistical analysis of trials in infant nutrition. The work of the CsoN have had great impact on paediatric nutrition and the committee will continue its important role by writing commentaries and systematic reviews and revising guidelines when required to inform and stimulate discussion among colleagues as well as stimulate training in paediatric nutrition by organising workshops and scientific meetings, training courses, and other approaches, and by interaction with other expert groups. PMID- 29596189 TI - Chapter 8. 50 Years of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN): Captivating Witness Reports of a Success Story. AB - Since the conception of an idea of a few paediatric gastroenterologists in Europe to create a society for Paediatric Gastroenterology in 1967, and its foundation in 1968, half a century has passed. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) now celebrates its 50th anniversary and its utmost success in combining clinical and scientific expertise in the fields of paediatric gastroenterology, haepatology, and nutrition. To describe this success story 14 of the still living presidents of ESPGHAN recount their impressions of the steady growth of ESPGHAN with all the historical facets from their own points of view. This historical view of ESPGHAN over the last 5 decades provides personal accounts of the development of all activities and creations of this great European Society. The Society started as a small family of experts in the field into a global working open society involved in a large variety of activities within the subspecialties, becoming a leading organisation in Europe and beyond. This unique view gives also a wonderful insight into the famous clinicians and researchers from all over Europe who have helped in the growth and development of ESPGHAN. By describing all these activities and collaborations it becomes clear that this astonishing pan-European enterprise was achieved by people who put considerable effort and time into the development of this society. Their statements serve as a historical source and reference for future evaluation of the first 50 years of ESPGHAN. In depicting different time episodes, and by assembling all the historical pieces of a puzzle together, the statements help to illustrate how a highly structured society such as ESPGHAN has evolved over the last 50 years, for what it stands for today and what is to be expected in the future. PMID- 29596190 TI - Chapter 9. Words From Partner Societies. AB - On the occasion of the 50th anniversary of the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN), its close partner associations submitted comments and felicitations which are presented here. These include words from the Latin American (LASPGHAN), North American (NASPGHAN) and Panarabian Societies (PASPGHAN) and the Commonwealth Association (CAPGHAN) of Paediatric Gastroenterology, Hepatology and Nutrition, the Federation of International Societies of Paediatric Gastroenterology, Hepatology and Nutrition (FISPGHAN), the European Academy of Pediatrics (EAP), the European Pediatric Association/Union of National Pediatric Societies (EPA-UNEPSA), the International Pediatric Association (IPA), the European Crohn's and Colitis Organisation (ECCO), European Society for Clinical Nutrition and Metabolism (ESPEN) , the Federation of European Nutrition Societies (FENS), and United European Gastroenterology (UEG). PMID- 29596191 TI - A 20-Year Experience with 202 Segmental Mandibulectomy Defects: A Defect Classification System, Algorithm for Flap Selection, and Surgical Outcomes. AB - BACKGROUND: This study establishes a novel and broadly applicable defect classification system and flap selection algorithm for segmental mandibulectomy defects that emphasize the importance of the soft-tissue deficit, in addition to that of the bony defect. METHODS: Between 1992 and 2011, 202 patients with mandibulectomy defects underwent immediate reconstruction performed by a single surgeon. Details of the bony and soft-tissue defects, recommendations for the most appropriate reconstruction for each clinical scenario, and surgical outcomes are presented. RESULTS: A total of 211 flaps were performed in 202 patients. Forty-one (19 percent) were nonosseous only, and 170 (81 percent) were osseous containing. The majority of osseous flaps were fibula osseous or osteocutaneous flaps (91 percent), and the majority of nonosseous flaps were vertical rectus abdominis myocutaneous flaps (68 percent). Flap selection was influenced by the number of soft-tissue zones resected; defects of one soft-tissue zone or less were predominantly reconstructed with an osseous flap, whereas defects that involved four or more zones underwent reconstruction with only a soft-tissue flap in 55 percent of cases. CONCLUSIONS: The algorithm for reconstruction of the mandibulectomy defect must include both nonosseous and osseous flaps based on defect size, location, and number of soft-tissue zones involved. As the extent of the soft-tissue defect increases, nonosseous flaps are preferred because of greater reliability of the skin island. The surgical outcomes associated with this algorithm are similar to or better than what is published in the literature. This series represents the largest reported single-surgeon experience with mandibulectomy defect reconstruction. PMID- 29596192 TI - Soft-Tissue Reconstruction of the Complicated Knee Arthroplasty: Principles and Predictors of Salvage. AB - BACKGROUND: Total knee arthroplasty is a common orthopedic procedure in the United States and complications can be devastating. Soft-tissue compromise or joint infection may cause failure of prosthesis requiring knee fusion or amputation. The role of a plastic surgeon in total knee arthroplasty is critical for cases requiring optimization of the soft-tissue envelope. The purpose of this study was to elucidate factors associated with total knee arthroplasty salvage following complications and clarify principles of reconstruction to optimize outcomes. METHODS: A retrospective review of patients requiring soft-tissue reconstruction performed by the senior author after total knee arthroplasty over 8 years was completed. Logistic regression and Fisher's exact tests determined factors associated with the primary outcome, prosthesis salvage versus knee fusion or amputation. RESULTS: Seventy-three knees in 71 patients required soft tissue reconstruction (mean follow-up, 1.8 years), with a salvage rate of 61.1 percent, mostly using medial gastrocnemius flaps. Patients referred to our institution with complicated periprosthetic wounds were significantly more likely to lose their knee prosthesis than patients treated only within our system. Patients with multiple prior knee operations before definitive soft-tissue reconstruction had significantly decreased rates of prosthesis salvage and an increased risk of amputation. Knee salvage significantly decreased with positive joint cultures (Gram-negative greater than Gram-positive organisms) and particularly at the time of definitive reconstruction, which also trended toward an increased risk of amputation. CONCLUSIONS: In revision total knee arthroplasty, prompt soft-tissue reconstruction improves the likelihood of success, and protracted surgical courses and contamination increase failure and amputations. The authors show a benefit to involving plastic surgeons early in the course of total knee arthroplasty complications to optimize genicular soft tissues. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III. PMID- 29596193 TI - Skin Rejuvenation through HIF-1alpha Modulation. AB - The constant intrinsic and extrinsic stress the skin is exposed to leads to significant impairments of the regenerative capacity of aging skin. Current skin rejuvenation approaches lack the ability to holistically support the biological processes that exhaust during aging skin degeneration, such as collagen production, cell migration and proliferation, and new vessel formation. Similar to chronic wounds, aged skin is characterized by dysfunction of key cellular regulatory pathways impairing regeneration. Recent evidence suggests that the same mechanisms hindering a physiologic healing response in chronic wounds are the basis of impaired tissue homeostasis in aged skin. Dysfunction of a main response-to-injury pathway, the hypoxia-inducible factor (HIF)-1alpha regulatory pathway, has been identified as pivotal both in chronic wounds and in aging skin degeneration. HIF-1alpha signaling is significantly involved in tissue homeostasis and neovascularization, resulting in the production of new collagen, elastin, and nourishing blood vessels. Modulating the functionality of this pathway has been demonstrated to significantly enhance tissue regeneration. In this review, we present an overview of the regenerative effects linked to the up regulation of HIF-1alpha functionality, potentially resulting in skin rejuvenation on both the cellular level and the tissue level.

AB - OBJECTIVE: Constrictive bronchiolitis (CB) is a poorly understood pulmonary manifestation of primary Sjogren syndrome (pSS). We aimed to clarify the presenting clinicoradiologic features and clinical course of pSS-associated CB through a retrospective cohort study. METHODS: We retrospectively identified 11 patients with pSS and CB (defined by mosaic pattern with air trapping on computed tomography) encountered at our institution over 9 years from 2007 to 2015. Presenting clinical features, laboratory results, radiologic findings, and clinical course were analyzed. RESULTS: Our patients were mostly women (91%), with a median age 53 years (range, 31-76 years) at the time of pulmonary symptom (dyspnea or cough) onset. Most (64%) were nonsmokers. Average interval between diagnosis of pSS and the onset of pulmonary symptoms was 4.4 years; in 4 patients (36%), CB was the presenting manifestation of pSS. Chest radiographs were normal (67%) or demonstrated hyperinflation (33%). Pulmonary function testing demonstrated airflow obstruction in 7 patients (63%), and 2 patients (18%) had an isolated reduction in diffusing capacity, whereas the remaining 2 patients manifested mixed physiology or normal results. Surgical lung biopsy was performed in 2 patients and confirmed the diagnosis of CB in both. Treatment was variable among our patients included glucocorticoids, hydroxychloroquine, mycophenolate mofetil, and cyclophosphamide. Among 6 patients with follow-up computed tomography and pulmonary function, the results remained stable or worsened. CONCLUSIONS: Constrictive bronchiolitis is a rare extraglandular manifestation and can sometimes be the presenting manifestation of pSS. This pulmonary manifestation is associated with an indolent clinical course and does not respond well to immunosuppressive therapy.

PMID- 29596208 TI - A Consensus Position Paper From REAL-PANLAR Group About the Methodological Approach for the Accreditation Process of Centers of Excellence in Rheumatoid Arthritis in Latin America. AB - BACKGROUND: By 2015, the World Health Organization reported that 1% of the world population suffered from rheumatoid arthritis (RA) and in Latin America (LATAM) between 0.5% and 1%. Previously, in May 2014, a consensus meeting was held in Barranquilla, Colombia, where the Project for Implementation and Accreditation of Centers of Excellence (CoE) in RA in LATAM was established, which then became an official special group of the Pan American League of Associations for Rheumatology (PANLAR). OBJECTIVE: The aim of this study was to define the methodological approach for the accreditation process of CoE in RA in LATAM. METHODS: A meeting was held in April 2015 with participation of the members of the REAL-PANLAR Steering Committee, and representatives of several LATAM countries, with the support of 2 experts in accreditation processes and models in Colombia. Then, in November 2015 in San Francisco and in November 2016 in Washington, the REAL-PANLAR Steering Committee met to discuss some final aspects of the project. RESULTS: The following steps for accreditation were defined: application for accreditation, issuance of the concept of assessment of the entity, accreditation decision, and monitoring accreditation. CONCLUSIONS: This is the second REAL-PANLAR consensus paper with the purpose to define the parameters for the accreditation process for future CoE in RA in LATAM.

PMID- 29596210 TI - Sacroiliitis in Children With Familial Mediterranean Fever. AB - BACKGROUND/OBJECTIVE: Familial Mediterranean fever (FMF) is an autosomal recessive disease, characterized by recurrent, self-limited attacks of fever with serositis. Various diseases were reported to be associated with FMF. The aim of this study was to investigate the frequency and characteristics of sacroiliitis in children with FMF. METHODS: Files of FMF patients who had been seen in 2 reference hospitals in Ankara were retrospectively evaluated. Patients with FMF and concomitant sacroiliitis were included to the study. All patients had magnetic resonance imaging evidence of sacroiliitis. RESULTS: Among 650 FMF patients, 17 (11 females, 6 males; mean age, 13.32 +/- 4.24 years) (2.6%) of them were found to have sacroiliitis. Familial Mediterranean fever diagnosis was done prior to sacroiliitis diagnosis in 11 patients (65%) and concurrently or afterward in 6 patients (35%). Ten patients had isolated sacroiliitis, and 7 had associated diseases (5 enthesitis-related arthritis, 1 psoriatic arthritis, and 1 ulcerative colitis). Arthritis (59%), arthralgia (77%), leg pain (71%), heel pain (41%), and enthesitis (29%) were common complaints. Sacroiliac tenderness was detected in 77%, and M694V mutation in almost 90% of the patients. All patients received colchicine therapy. Additionally, 14 of them were treated with nonsteroidal anti-inflammatory drugs, 10 were on sulfasalazine treatment, and 7 of them were on biological agents. CONCLUSIONS: Sacroiliitis can be seen in patients with FMF during childhood, and M694V mutation seems to be a susceptibility factor for its development. Inflammatory low-back pain and leg and heel pain could suggest sacroiliitis. PMID- 29596212 TI - Perioperative Nutritional Optimization in Spine Surgery. AB - Nutritional optimization in patients undergoing spine surgery is important as improved surgical outcomes and decreased rates of complications have been noted in optimized patients. With the increasingly high numbers of elderly patient and patients with metabolic comorbidities undergoing spine procedures, perioperative nutritional status should be enhanced for the best possible surgical outcomes. Methods of optimization include preoperative screening with Nutritional Risk Score or other scoring systems, looking for changes in body mass index, detecting sarcopenia, and screening for metabolic abnormalities. Assessment of blood glucose, electrolytes, cholesterol, vitamin levels, visceral proteins, and lean body mass must be done preoperatively and close monitoring should be continued postoperatively. Albumin helps to determine the health status of patients before surgery and prealbumin as a predictor of surgical outcomes is being investigated. Malnourished patients should be given balanced diets replenishing key nutrient deficits, glucose should be maintained with sliding scale insulin or continuous infusions and immunonutrition may be implemented. Postoperatively, patients should initiate a diet as soon as possible to decrease overall length of stay and complication rates, facilitating return to normal activities. PMID- 29596213 TI - A Prospective Single-blind Randomized Controlled Trial of Chewing Gum on Bowel Function Recovery After Posterior Spinal Fusion Surgery for Adolescent Idiopathic Scoliosis. AB - PURPOSE: To evaluate the effectiveness of chewing gum on promoting bowel function recovery in adolescent idiopathic scoliosis patients undergoing surgical correction. MATERIALS AND METHODS: Adolescent idiopathic scoliosis patients scheduled for posterior spinal fusion surgery at our institution were randomized to either group 1 (chewing gum) or group 2 (control). The primary endpoints were time to flatus, time to bowel movement, length of hospital stay, and time to liquid or solid. The secondary endpoints were postoperative opioid consumption, incidence of complications, pain scores, and nausea scores. In addition, a meta analysis of available data from the literature was performed identifying 2 studies with quantitative data on the efficacy of gum chewing after scoliosis correction surgery. RESULTS: In total, 125 patients (63 gum; 62 control) were included in our analysis after randomization. There was no significant difference in time to first flatus (P=0.087), time to bowel movement (P=0.307), time to liquid or solid, length of postoperative hospital stay (P=0.954), postoperative complications, opioid consumption, and postoperative nausea scores between the 2 groups. The postoperative pain scores on postoperative day 1 were significantly lower (P=0.027). There was a significant decrease in the time to the first flatus for patients having selective thoracic fusion in both groups than those having fusion to lumbar spine. Meta-analysis also indicated there was no significant difference in outcomes of bowel function between the 2 groups. CONCLUSIONS: Our institutional data and meta-analysis collaboratively suggested that chewing gum did not hasten the return of bowel function. PMID- 29596214 TI - Natural History and Prognostic Factors of Cholangiocarcinoma With Spinal Metastasis: A 10-Year Single Center Study. AB - STUDY DESIGN: This is a retrospective analysis. OBJECTIVE: The aim of this study was to determine the epidemiology, survival, and prognostic factors for cholangiocarcinoma (CCA) with spinal metastasis. SUMMARY OF BACKGROUND DATA: CCA is an epithelial cell malignancy of the bile duct, and a frequent site for its metastasis is the spine. Many areas of Asia are endemic for CCAs. To date, there is limited data on the epidemiology, natural history, and prognostic factors of CCA with spinal metastasis, which is crucial for better management and treatment of the disease. MATERIALS AND METHODS: Patients diagnosed with CCA were recruited to our study, in order to identify cases with spinal metastasis. The survival rate was estimated by the Kaplan-Meier method. The univariate and multivariate analyses of tumor-specific and spinal metastatic factors were performed to identify the independent factors that affect survival. RESULTS: From 2006 to 2015, 4585 CCA patients were identified and 182 of these patients had spinal metastasis. The overall median survival of patients with spinal metastasis was 88 days. Serum carcinoembryonic antigen <5 ng/mL, carbohydrate antigen 19-9 <39 U/mL, albumin >=3.5 g/L, and Frankel score D-E were found to be independent factors that resulted in better survival in a multivariate Cox regression analysis. CCA resection or spinal surgery did not prolong the survival of patients with spinal metastasis. CONCLUSION: Spinal surgery should be considered for CCA patients with spinal metastasis, who have a favorable prognosis, and are likely to live long enough to benefit from surgery. The aim is to palliate the symptoms and not as much to improve the survival. PMID- 29596215 TI - Incidence and Risk Factors for Proximal Junctional Kyphosis: Results of a Multicentric Study of Adult Scoliosis. AB - STUDY DESIGN: This was a retrospective multicentric study. OBJECTIVE: The objective of this study was to determine the different risk factors for development of proximal junctional kyphosis (PJK) in patients with adult scoliosis. SUMMARY OF BACKGROUND DATA: This study was conducted as the reasons for development of PJK in adult scoliosis are still not clear. MATERIALS AND METHODS: In total, 314 patients met the inclusion criteria. The main outcome measure was the PJK, as described by Glattes and colleagues. Extent of the instrumentation, operative time, bleeding, and the use of an osteotomy as well as the type of proximal anchorage were collected. Radiologic variables included preoperative Cobb angles of the lumbar and the thoracic curvatures, pelvic parameters, lumbar lordosis, thoracic kyphosis, and sagittal vertical axis. All measures were performed using the KEOPS software. RESULTS: The mean follow-up of this series was 2.5 years with a female to male ratio of 6.6/1 and a mean age of 56.66 years. The incidence of PJK was 25%. Proximal fixation extended to the proximal thoracic spine (TS) in 39%, to the middle TS in 39.5% of cases, and to the thoracolumbar junction in 20.4%, with a higher incidence of PJK noted in the first group. The proximal anchors had no effect on PJK incidence. Age as well as body mass index had a positive correlation to the incidence of PJK. The association, fusion to sacrum and fusion to the upper TS, is associated with the highest incidence of PJK. Preoperative pelvic tilt had a positive correlation with PJK occurrence. Finally, revision for PJK occurred in 2.3% of all patients and accounted for 15% of revisions. CONCLUSIONS: Increased age, as well as increased body mass index, is a risk factor for the development of PJK. The proximal extent of the construct is also shown to be a risk factor for PJK, but fusion to the sacrum is a risk factor only if fusion extends to the proximal TS. Moderate PJK was observed with undercorrection of the sagittal balance and severe PJKs with overcorrection of the sagittal balance. LEVEL OF EVIDENCE: Level IV. PMID- 29596216 TI - Reduction of Inappropriate Antimicrobial Prescriptions in a Tertiary Neonatal Intensive Care Unit Following Antimicrobial Stewardship Care Bundle Implementation. AB - BACKGROUND: Our objective was to evaluate the appropriateness of antibiotic prescriptions in the neonatal intensive care unit (NICU) using standardised criteria and determine the effects of an antimicrobial stewardship programme (ASP) on patterns of antibiotic usage. METHODS: A retrospective audit of antibiotic use from July 2010-June 2013 was conducted, focusing on prescriptions of vancomycin, cefotaxime, meropenem and linezolid for >3 calendar days. We evaluated the appropriateness of each course of antibiotic treatment based on the Centers for Disease Control and Prevention (CDC) 12-Step Guidelines to Prevent Antimicrobial Resistance (Steps 4, 6 and 9). An ASP was introduced in August 2014, and the same audit criteria were applied to review antimicrobial use in the subsequent 12 months. RESULTS: In the pre-ASP era, 26.3%, 12.1%, 11.4% and 0% of meropenem, cefotaxime, vancomycin and linezolid courses, respectively, were inappropriate. The most common instance of inappropriate utilisation included failure to use narrower-spectrum antimicrobials when appropriate. After the introduction of ASP programme, 22.2%, 7.5%, 5.4% and 0% of meropenem, cefotaxime, vancomycin and linezolid courses, respectively, were inappropriate. The numbers of inappropriate antibiotic-days/1000 days of therapy with meropenem, cefotaxime and vancomycin changed from 1.89 to 1.96 (rate ratio RR=1.04 [0.70,1.52]), 3.56 to 1.73 (RR=0.49[0.33,0.71]) and 2.70 to 1.01 (RR=0.37[0.22,0.60]), respectively. In sub-group analysis, very-low-birth-weight infants (VLBW, birth weight<1500grams) showed no improvement in the rates of inappropriate antibiotic prescriptions. CONCLUSION: In this study, we found that ASP initiatives can be applied in neonatal populations to reduce inappropriate antimicrobial prescriptions, though a different approach may be needed among VLBW infants. PMID- 29596218 TI - Dietary Supplementation with Medium-Chain Triglycerides Reduces Candida Gastrointestinal Colonization in Preterm Infants. AB - BACKGROUND: Candida is an important cause of infections in premature infants. Gastrointestinal colonization with Candida is a common site of entry for disseminated disease. The objective of this study was to determine whether a dietary supplement of medium-chain triglycerides (MCTs) reduces Candida colonization in preterm infants. METHODS: Preterm infants with Candida colonization (n=12) receiving enteral feedings of either infant formula (n=5) or breastmilk (n=7) were randomized to MCT supplementation (n=8) or no supplementation (n=4). Daily stool samples were collected to determine fungal burden during a 3 week study period. Infants in the MCT group received supplementation during 1 week of the study period. The primary outcome was fungal burden during the supplementation period as compared to the periods before and after supplementation. RESULTS: Supplementation of MCT led to a marked increase in MCT intake relative to unsupplemented breast milk or formula as measured by capric acid content. In the treatment group, there was a significant reduction in fungal burden during the supplementation period as compared to the period before supplementation (RR = 0.15, p = 0.02), with a significant increase after supplementation was stopped (RR = 61, p < 0.001). Fungal burden in the control group did not show similar changes. CONCLUSIONS: Dietary supplementation with MCT may be an effective method to reduce Candida colonization in preterm infants.

PMID- 29596219 TI - Efficacy and Safety of Echinocandins for the Treatment of Invasive Candidiasis in Children: A Meta-Analysis. AB - BACKGROUND: Echinocandins are recommended for the treatment of suspected or confirmed invasive candidiasis (IC) in adults. Less is known about the use of echinocandins for the management of IC in children. The aim of this study was to investigate the overall efficacy and safety of echinocandin class in neonatal and pediatric patients with IC. METHODS: PubMed, Cochrane Central, Scopus and Clinical trial registries were searched up to July 27, 2017. Eligible studies were randomized trials (RCTs) that evaluated the efficacy and safety of any echinocandin versus agents of other antifungal classes for the treatment of IC in pediatric patients. The primary outcome was treatment success with resolution of symptoms and signs, and absence of IC. In the meta-analysis a random effects model was used, and the odds ratio (OR) and 95% confidence intervals (CI) were calculated. RESULTS: Four randomized clinical trials (324 patients), 2 confirmed IC (micafungin vs. liposomal amphotericin B and caspofungin vs. liposomal amphotericin B) and 2 empirical therapy trials (caspofungin vs. deoxycholate amphotericin B and caspofungin vs. liposomal amphotericin B) were included. There was no significant difference between echinocandins and comparator in terms of treatment success (OR=1.61, 95% CI 0.74-3.50) and incidence of treatment-related adverse events (OR=0.70, 95% CI 0.39-1.26). However, fewer children treated with echinocandins discontinued treatment due to adverse events than amphotericin B formulations (OR=0.26, 95% CI 0.08-0.82, p=0.02). CONCLUSIONS: In the treatment of IC in children echinocandins show non-inferior efficacy compared to amphotericin B formulations with fewer discontinuations than in comparator arm. PMID- 29596220 TI - Fusobacterium necrophorum as an Emerging Pathogen of Acute Mastoiditis. AB - BACKGROUND: Recent reports have reported an increase in the incidence of acute mastoiditis due to Fusobacterium necrophorum. However, the crude incidence and the specific clinical and laboratory characteristics of F.necrophorum mastoiditis in children have not been described. Our aim was to describe these features, in order to identify high-risk patients. METHODS: The electronic medical records of all children with acute mastoiditis at a tertiary medical center between 7/2011 and 12/2015 were analyzed. Using a stepwise logistic regression to identify independent risk factors for F. necrophorum, we formulated a predictive model. RESULTS: F. necrophorum was identified in 13% (19/149) of mastoiditis cases with an identifiable agent. Its incidence increased 7-fold from 2.8% in 2012 to 20.4% in 2015 (p=0.02). F. necrophorum infection had unique clinical, laboratory and prognostic features. The vast majority had complications and underwent surgical intervention. The predictive model used four parameters to define high-risk patients for F. necrophorum infection at admission: females, winter/spring season, prior antibiotic treatment and a CRP value>20 mg/dL (area under ROC curve 0.929). CONCLUSIONS: Clinicians should be aware of the increasing incidence of F.necrophorum mastoiditis and consider anaerobic cultures and specific anaerobic coverage in high-risk patients. PMID- 29596221 TI - Increasing Prevalence of Pediatric Drug-resistant Tuberculosis in Mumbai, India, and Its Outcome. AB - BACKGROUND: The prevalence and type of Drug resistant tuberculosis (DR-TB) was evaluated pre- and post-2013, and outcome was studied. METHODS: Descriptive retrospective study. Children were defined as having DR-TB on the basis of GeneXpert or line probe assay and/or drug susceptibility testing (DST) of M. tuberculosis grown on culture or from contact's DST. RESULTS: The prevalence of DR-TB was 110 of 1145 cases (9.6%), which showed an increase, compared with 5.6% pre-2010 and 7% in 2010-2013 (P = 0.014408). Twenty-two children (20%) had pulmonary-TB and 88 (80%) had extra-pulmonary-TB with disseminated-TB being the most common presentation in 31 children (28.18%). Ninety-six children (87.3%) were bacteriologically confirmed TB cases, and 14 (12.7%) were clinically diagnosed-TB and treated as per contact DST. Eight cases (7.2%) were monoresistant, 7 (6.3%) polyresistant, MDR-TB seen in 28 patients (25.45%), 32 (29.09%) had pre-XDR-TB, 9 (8.18%) had XDR-TB and 12 (10.9%) were rifampicin resistant. Ethionamide resistance increased from 26.1% pre-2013 to 60.8% post 2013 (P = 0.014408) and ofloxacin resistance rose from 30.4% pre-2010, to 47.6% in 2010-2013 and 56.9% post-2013 (P = 0.080863). Moxifloxacin resistance showed an acute rise from 8.7% pre-2010, to 46% in 2010-2013 and 57% post-2013 (P = 0.000275). Thirty-three patients (30%) had completed their treatment, 21 (19.09%) were lost to follow-up and 56 (50.09%) patients are still on treatment. CONCLUSIONS: DR-TB is increasing in Mumbai, India. Based on the DST results, individualised therapy would be recommended. PMID- 29596223 TI - Syphilis Elimination: Lessons Learned Again. AB - It is estimated that approximately 20 million new sexually transmitted infections (STIs) occur each year in the United States. The federally funded sexually transmitted disease prevention program implemented by Centers for Disease Control and Prevention is primarily focused on the prevention and control of the three most common bacterial STIs: syphilis, gonorrhea, and chlamydia. A range of factors facilitate the transmission and acquisition of STIs, including syphilis. In 1999, Centers for Disease Control and Prevention launched the National Campaign to Eliminate Syphilis from the United States. The strategies were familiar to public health in general and to sexually transmitted disease control in particular: (1) enhanced surveillance, (2) expanded clinical and laboratory services, ((3) enhanced health promotion, (4) strengthened community involvement and partnerships, and (5) rapid outbreak response. This national commitment to syphilis elimination was not the first effort, and like others before it too did not succeed. However, the lessons learned from this most recent campaign can inform the way forward to a more comprehensive approach to the prevention and control of STIs and improvement in the nation's health. PMID- 29596222 TI - A Phase 3 Study of Micafungin Versus Amphotericin B Deoxycholate in Infants With Invasive Candidiasis. AB - BACKGROUND: Amphotericin B deoxycholate (AmB-D) is standard of care treatment for neonatal invasive candidiasis (IC). Micafungin (MCA) has broad-spectrum fungicidal activity against Candida spp. We compared the efficacy and safety of intravenous MCA with intravenous AmB-D and assessed the pharmacokinetics of MCA in infants >2-120 days of age with proven IC in a phase 3, randomized, double blind, multicenter, parallel-group, noninferiority study (NCT00815516). METHODS: Infants were randomized 2:1 to MCA (10 mg/kg/d) or AmB-D (1 mg/kg/d) for >=21 days. Primary efficacy endpoint was fungal-free survival (FFS) 1 week after last study drug dose. MCA population pharmacokinetics included simulated area under the curve (AUC) at steady state and maximum plasma concentration after 2-hour infusion. AUC pharmacodynamic target exposure was 170 ug.h/mL. RESULTS: Thirty infants received MCA (n = 20) or AmB-D (n = 10). The trial was terminated early because of slow recruitment. FFS was observed in 12 of 20 [60%; 95% confidence interval (CI): 36%-81%] MCA-group infants and in 7 of 10 (70%; 95% CI: 35%-93%) AmB-D-group infants. The most common treatment-emergent adverse events were anemia [MCA: n = 9 (45%); AmB-D: n = 3 (30%)] and thrombocytopenia [n = 2 (10%) and n = 3 (30%), respectively]. Model-derived mean AUC at steady state for MCA was 399.3 +/- 163.9 ug.h/mL (95% prediction interval: 190.3-742.3 ug/mL); steady state and maximum plasma concentration after 2-hour infusion was 31.1 +/- 10.5 ug/mL (95% prediction interval: 17.0-49.7 ug/mL). MCA exposures were above the AUC pharmacodynamic target exposure. CONCLUSIONS: Within the study limitations, infants with IC treated with MCA achieved similar FFS compared with AmB-D. Both agents were safe and well tolerated. PMID- 29596224 TI - CDC Syphilis Summit - Diagnostics and Laboratory Issues. AB - Syphilis, caused by the bacterium Treponema pallidum, is on the rise in the United States (US) particularly among men who have sex with men (MSM). The disease is complex with varied clinical manifestations and challenges remain in the laboratory diagnostic setting because T. pallidum is non-cultivable and no single test can accurately diagnose all stages of the disease. There are missed opportunities for the use of direct detection tests in primary and secondary (P&S) syphilis. The increasing use of different reverse sequence algorithms for serology testing without validation in populations with varying risks for syphilis makes the interpretation of test results difficult; this has led to concerns about diagnostic errors or overtreatment. On the other hand, the traditional algorithm may miss some early primary syphilis cases, which is of concern in high-risk populations. The potential utility of rapid syphilis serology tests in different settings or populations remains to be determined. The implementation of better tests and appropriate testing algorithms together with laboratory guidelines for test use in general will lead to better diagnostic options for syphilis. PMID- 29596226 TI - Subsequent HIV Diagnosis Risk After Syphilis in a Southern Black Population. AB - BACKGROUND: Southern non-Hispanic black persons are disproportionately represented in the HIV epidemic. Those previously diagnosed as having syphilis are at significant risk to become HIV infected within 36 months. Effective prevention strategies such as preexposure prophylaxis should be offered to those at highest risk to maximize prevention efforts. METHODS: HIV-negative persons diagnosed as having primary or secondary (P&S) syphilis during 1998-2014 were matched with incident HIV cases diagnosed during 1998-2016 in Shelby County Tennessee. Person-year HIV incidence rate, Kaplan-Meier survival estimates, and Cox proportional regression model analyses were performed to explore predicting risk factors and quantifying risk factors associated with HIV-free survival time frames. RESULTS: Among 2032 HIV-negative non-Hispanic black Shelby County residents diagnosed as having P&S syphilis, 139 (6.8%) were subsequently diagnosed as having HIV infection. Men who have sex with men (MSM) experienced the highest incidence of HIV diagnosis rate (4.98 per 100 person-years, 95% confidence interval, 4.76-5.2). Being male, MSM, younger than 30 years, or coinfected with gonorrhea increased risk of HIV acquisition 2.32, 11.80, 1.67, and 2.44 times, respectively, compared with being female, heterosexual men, 30+ years old, or not infected with other sexually transmitted infections. CONCLUSIONS: Among our population diagnosed as having P&S syphilis, 1 in 6 MSM and 1 in 16 persons coinfected with gonorrhea were subsequently diagnosed as having HIV during 36 months of follow-up. These findings have implications for HIV screening and recruitment as priority preexposure prophylaxis candidates.

AB - : The Great London Smog of December 1952 lasted five days and killed up to 12,000 people. The smog developed primarily because of extensive burning of high-sulfur coal. The health effects were both immediate and long lasting, with a recent study revealing an increased likelihood of childhood asthma development in those exposed to the Great Smog while in utero or during their first year of life. Subsequent pollution legislation-including the U.S. Clean Air Act and its amendments-have demonstrably reduced air pollution and positively impacted health outcomes. With poor air quality events like the Great Smog continuing to occur today, nurses need to be aware of the impact such environmental disasters can have on human health.

PMID- 29596265 TI - A Multidisciplinary Discharge Timeout Checklist Improves Patient Education and Captures Discharge Process Errors. AB - OBJECTIVE: To design and implement a discharge timeout checklist, and to assess its effects on patients' understanding as well as the potential impact on preventable medical errors surrounding hospital discharges to home. METHODS: Based on the structure successfully used for surgical procedures and using the Model for Improvement framework, we designed a discharge checklist to review and assess patients' understanding of discharge medications, catheters, home care plans, follow-up, symptoms, and who to call with problems after discharge. In parallel, we developed a process of integrating the checklist into the discharge process after routine discharge procedures were completed. We used the checklists to assess patients' level of understanding and need for additional education as well as changes in discharge documentation; we also noted whether good catches of significant errors in the discharge process occurred. RESULTS: Over 6 months of study, 190 discharge timeouts out of 429 eligible discharges were completed. Additional education was provided in 53 of 190 discharge timeouts (27.8%), with 62% of this education being related to medications. Twenty-one (11.1%) discharge timeouts resulted in at least one change to the discharge documentation or a good catch. CONCLUSIONS: A multidisciplinary discharge timeout directly involving the patient can be effective in targeting additional areas for patient education and in potentially reducing preventable adverse events. PMID- 29596266 TI - The Utility of Failure Modes and Effects Analysis of Consultations in a Tertiary, Academic, Medical Center. AB - BACKGROUND: Failure modes and effects analysis (FMEA) is a tool used to identify potential risks in health care processes. We used the FMEA tool for improving the process of consultation in an academic medical center. METHODS: A team of 10 staff members-5 physicians, 2 quality experts, 2 organizational consultants, and 1 nurse-was established. The consultation process steps, from ordering to delivering, were computed. Failure modes were assessed for likelihood of occurrence, detection, and severity. A risk priority number (RPN) was calculated. An interventional plan was designed according to the highest RPNs. Thereafter, we compared the percentage of completed computer-based documented consultations before and after the intervention. RESULTS: The team identified 3 main categories of failure modes that reached the highest RPNs: initiation of consultation by a junior staff physician without senior approval, failure to document the consultation in the computerized patient registry, and asking for consultation on the telephone. An interventional plan was designed, including meetings to update knowledge of the consultation request process, stressing the importance of approval by a senior physician, training sessions for closing requests in the patient file, and reporting of telephone requests. The number of electronically documented consultation results and recommendations significantly increased (75%) after intervention. CONCLUSION: FMEA is an important and efficient tool for improving the consultation process in an academic medical center. PMID- 29596267 TI - A Stewardship Program to Optimize the Use of Inhaled Nitric Oxide in Pediatric Critical Care. AB - PURPOSE: Inhaled nitric oxide (iNO) is a pulmonary vasodilator that is approved for use in term and near-term neonates with hypoxic respiratory failure associated with evidence of pulmonary hypertension. However, it is commonly used in infants and children to treat a variety of other cardiopulmonary diseases associated with pulmonary hypertension and hypoxic respiratory failure. In critically ill children, iNO therapy may be continued for a prolonged period, and this increases the risk for adverse consequences including toxicity and unnecessary costs. We implemented an iNO Stewardship Program with the aim of improving adherence to guidelines and reducing unnecessary iNO utilization. METHODS: Between April 1, 2011, and March 31, 2015, a before and after cohort study was conducted at The Hospital for Sick Children. Prospective iNO usage and outcome variables in the poststewardship period were examined. RESULTS: Patient characteristics and outcomes were similar before and after stewardship implementation. The number of iNO therapy courses were also similar in the before and after period. Inhaled nitric oxide utilization in the pediatric intensive care unit and the cardiac critical care unit decreased from 15 765 hours in the prestewardship period (April 2011 to March 2013) to 10 342 hours in the poststewardship period (April 2013 to March 2015), with significant improvement in adherence to the iNO guideline and a small decrease in expenditure (3%). CONCLUSION: Implementation of the iNO Stewardship was successful at reducing overall iNO utilization. This quality improvement initiative helped us optimize practice and subsequently expand the methodology to inform the clinical indication for iNO. PMID- 29596268 TI - Characteristics of Volunteer Coaches in a Clinical Process Improvement Program. AB - INTRODUCTION: The Partners Clinical Process Improvement Leadership Program provides quality improvement training for clinicians and administrators, utilizing graduates as volunteer peer coaches for mentorship. We sought to understand the factors associated with volunteer coach participation and gain insight into how to improve and sustain this program. METHODS: Review of coach characteristics from course database and survey of frequent coaches. RESULTS: Out of 516 Partners Clinical Process Improvement Leadership Program graduates from March 2010 to June 2015, 117 (23%) individuals volunteered as coaches. Sixty-one (52%) individuals coached once, 31 (27%) coached twice, and 25 (21%) coached 3 or more times. There were statistically significant associations between coaching and occupation (P = .005), Partners Clinical Process Improvement Leadership Program course taken (P = .001), and course location (P = .007). Administrators were more likely to coach than physicians (odds ratio: 1.75, P = .04). Reasons for volunteering as a coach included further development of skills, desire to stay involved with program, and enjoying mentoring. Reasons for repeated coaching included maintaining quality improvement skills, expanding skills to a wider variety of projects, and networking. CONCLUSIONS: A peer graduate volunteer coach model is a viable strategy for interprofessional quality improvement mentorship. Strategies that support repeat coaching and engage clinicians should be promoted to ensure an experienced and diversified group of coaches.

AB - Despite the increase in quality improvement (QI) education both in practice and in health professions' education, gaps exist in the usefulness and success of QI projects. Barriers to successful QI are a result of delays in implementation, teamwork issues, and lack of QI knowledge. These barriers can be addressed using a QI Coach. A QI Coach is an expert in QI principles who has excellent communication and collaboration skills, and is experienced with organizational policies. The purpose of this article is to (a) describe the VA Quality Scholars (VAQS) QI Coach Model that includes the role of a coach and effective coaching strategies and (b) discuss lessons learned from the application of the VAQS QI Coach Model. The QI Coach facilitates success by providing novice QI teams with practical skills, encouragement, and support. PMID- 29596270 TI - An Assessment of Organizational Health Literacy Practices at an Academic Health Center. AB - BACKGROUND: Organizational health literacy is the degree to which an organization considers and promotes the health literacy of patients. Addressing health literacy at an organizational level has the potential to have a greater impact on more health consumers in a health system than individual-level approaches. OBJECTIVE: The purpose of this study was to assess health care practices at an academic health center using the 10 attributes of a health-literate health care organization. METHODS: Using a survey research design, the Health Literate Healthcare Organization 10-Item Questionnaire was administered online using total population sampling. Employees (N = 10 300) rated the extent that their organization's health care practices consider and promote patients' health literacy. Differences in responses were assessed using factorial analysis of variance. RESULTS: The mean response was 4.7 on a 7-point Likert scale. Employee training and communication about costs received the lowest ratings. Univariate analyses revealed that there were no statistically significant differences (P = .05) by employees' health profession, years of service, or level of patient contact. There were statistically significant differences by highest education obtained with lowest ratings from employees with college degrees. CONCLUSIONS: Survey responses indicate a need for improvements in health care practices to better assist patients with inadequate health literacy. PMID- 29596271 TI - Health Literacy Demands of Patient-Reported Evaluation Tools in Orthopedics: A Mixed-Methods Case Study. AB - BACKGROUND: In response to an assessment of organizational health literacy practices at a major academic health center, this case study evaluated the health literacy demands of patient-reported outcome measures commonly used in orthopedic surgery practices to identify areas for improvement. METHODS: A mixed-methods approach was used to analyze the readability and patient feedback of orthopedic patient-reported outcome materials. Qualitative results were derived from focus group notes, observations, recordings, and consensus documents. Results were combined to formulate recommendations for quality improvement. RESULTS: Readability results indicated that narrative portions of sample patient outcome tools were written within or below the recommended eighth-grade reading level (= 5.9). However, document literacy results were higher than the recommended reading level (= 9.8). Focus group results revealed that participants had consensus on 8 of 12 plain language best practices, including use of bullet lists and jargon or technical words in both instruments. CONCLUSIONS: Although the typical readability of both instruments was not exceedingly high, appropriate readability formula and assessment methods gave a more comprehensive assessment of true readability. In addition, participant feedback revealed the need to reduce jargon and improve formatting to lessen the health literacy demands on patients. As clinicians turn more toward patient-reported measures to assess health care quality, it is important to consider the health literacy demands that are inherent in the instruments they are given in our health systems.

AB - STUDY DESIGN: Retrospective image-based analysis. OBJECTIVE: To measure endplate three-dimensional (3D) geometry, endplate changes in vivo and to investigate correlations between disc degeneration and endplate 3D geometry dependent on symptoms of low back pain (LBP). SUMMARY OF BACKGROUND DATA: It has been hypothesized that alteration of load transmission from the nucleus pulposus to the annulus fibrosus affects vertebral endplate geometry. METHODS: 3D surface models of inferior/superior lumbar endplates were created from computed tomography scans of n = 92 volunteers with and without LBP. Disc degeneration was evaluated using Pfirrmann scale. Concavity in both coronal and sagittal planes was assessed with the Concavity Index (unitless; larger than 1: concave; flat: 1; and less than 1: convex, respectively). Endplate area and disc height distribution were computed and the effects from demographics and spinal degeneration were sought with an analysis of variance model. RESULTS: Both sagittal and coronal planes revealed significantly decreased concavity in those with terminal grade 5 disc degeneration (mean 0.833 +/- 0.235) compared to the other grades in the cohort. Older subjects presented with larger endplate areas than the younger subjects (P = 0.0148) at L4-S1. Overall, symptomatic subjects had significantly larger endplate areas (P = 0.022), especially at the lower lumbar levels (P < 0.001). Analysis of variance showed that sex, disc level, disc degeneration grade, and disc height reached significance (P < 0.0001) as influential parameters in both Concavity Index cases. CONCLUSION: With advancing intervertebral disc degeneration, endplates become more convex over time in both sagittal and coronal planes. Our findings implicate the endplate changes with advancing disc degeneration in the shift in load transmission from the nucleus pulposus to the annulus fibrosus, resulting in changes within the curvature of the endplates. This is also the first study to describe the direct impact of age, sex, and LBP on vertebral endplate anatomy. LEVEL OF EVIDENCE: 5. PMID- 29596279 TI - Electronic Medical Record in the ED: A Cross-Sectional Survey of Resuscitation Documentation Practices and Perceptions Among Emergency Department Clinicians. AB - OBJECTIVES: The aims of this study were to describe current practices in nursing documentation of trauma and medical resuscitations across emergency departments (EDs) and explore physicians' and nurses' perceptions of electronic medical record (EMR) use for nursing documentation of resuscitations. METHODS: An anonymous Web-based survey was developed and distributed to a convenience sample of ED physicians and nurses in the United States. RESULTS: Of 438 respondents, 154 were nurses; 97.2% of respondents reported that their EDs use EMR generally. Of those, 51.2% use EMR to document resuscitations. When describing documentation processes, 19% (95% confidence interval [CI], 15%-23%) reported direct documentation on EMR, 18% (95% CI, 14%-21%) reported documenting on paper before transferring to EMR, and 22% (95% CI, 18%-26%) reported simultaneously documenting on EMR and paper. Thirty-seven percent of respondents reported that the "documentor" frequently performs other tasks during resuscitations. Few nurses (39.6%) and physicians (26.4%) perceived EMR as more efficient than paper. Nurses (66.2%) and physicians (51.8%) perceived paper as more complete than EMR. Few nurses (31.6%) and physicians (25.6%) agreed that paper would facilitate continuity of care better than EMR. No associations between nurses' perceptions of EMR, professional experience, or technology use were found. CONCLUSIONS: Although EMR adoption was common among respondents, only half reported using EMR to document resuscitations. Even fewer reported documenting directly on EMR, whereas a significant proportion reported processes that may be inefficient, redundant, or prone to errors. Respondents endorsed mostly negative perceptions of EMR. Our findings suggest that there may be factors inherent to resuscitations and the existing EMR interfaces that render documenting resuscitations on EMR uniquely challenging. PMID- 29596280 TI - Adolescent Sexual Behavior and Emergency Department Use. AB - OBJECTIVES: The objective of this study was to determine whether adolescents in emergency departments (EDs) who report engaging in high-risk sexual behaviors are less likely to identify a primary care provider (PCP) and more likely to access the ED than their sexually inexperienced peers. METHODS: This was a secondary analysis of adolescents presenting to a pediatric ED with non-sexually transmitted infection (STI)-related complaints who completed surveys to assess sexual behavior risk and health care access. We measured differences in self reported PCP identification, preferential use of the ED, and number of ED visits over a 12-month period by sexual experience. Secondary outcomes included clinician documented sexual histories and STI testing. RESULTS: Of 758 patients meeting inclusion criteria, 341 (44.9%) were sexually experienced, and of those, 129 (37.8%) reported engaging in high-risk behavior. Participants disclosing high risk behavior were less likely to identify a PCP (adjusted odds ratio, 0.5; 95% confidence interval [CI], 0.3-0.9), more likely to prefer the ED for acute care issues (adjusted odds ratio, 1.6; 95% CI, 1.0-2.6), and had a higher rate of ED visits (adjusted relative risk, 1.2; 95% CI, 1.0-1.3) compared with sexually inexperienced peers. Among patients disclosing high-risk behavior, 10.9% had clinician-documented sexual histories and 2.6% underwent STI testing. CONCLUSION: Adolescents who reported engaging in high-risk sexual behaviors were less likely to identify a PCP, as well as more likely to prefer ED-based care and make more ED visits. However, ED clinicians infrequently obtained sexual histories and performed STI testing in asymptomatic youth, thereby missing opportunities to screen high-risk adolescents who may lack access to preventive care. PMID- 29596281 TI - Chikungunya in a Pediatric Traveler. AB - Chikungunya is a mosquito-transmitted virus found primarily in Africa and Asia. In late 2013, chikungunya virus emerged in the Western hemisphere, spreading from the Caribbean to South, Central, and North America (MMWR Morb Mortal Wkly Rep. 2014;63:1121-1128). Symptoms can be similar to nonspecific viral presentations including fever, joint pain, joint swelling, and rash. The diagnosis of infectious tropical diseases in the emergency department often requires a high index of suspicion, given the nonspecific early findings that characterize many of these tropical diseases. This report presents a case of chikungunya in a pediatric patient traveling from Guatemala to the United States. Proper recognition of infection and diagnosis are vital from a public health perspective. Considering patients will remain viremic for up to a week and potentially expose local mosquitoes to infection, it is important to educate the patient on mosquito bite prevention in geographic areas of the United States where competent mosquito vectors exist as a means of avoiding further spread. PMID- 29596282 TI - Intimate Partner Violence Educational Materials in the Acute Care Setting: Acceptability and Impact on Female Caregiver Attitudes Toward Screening. AB - OBJECTIVES: This study aimed to determine acceptability of intimate partner violence (IPV) materials and effect of the materials on caregiver attitudes toward IPV screening. METHODS: We used an anonymous computerized survey to assess approval of IPV materials and screening, and willingness to disclose IPV in response to screening among mothers bringing a child to an urban pediatric emergency department or 2 suburban pediatric urgent care centers affiliated with a free-standing academic children's hospital. We compared responses between participants recruited before and after display of the IPV materials, as well as between subgroups, using chi tests. RESULTS: A total of 522 participated (predisplay, n = 261; postdisplay, n = 261). More subjects in the postdisplay group approved of display of IPV materials in pediatric emergency department/urgent care center restrooms (94% pre vs 98% post, P = 0.04) and examination rooms (94% pre vs 98% post, P = 0.01). We found no differences in acceptability of IPV screening between the pre and post groups (73% pre and post, P = 0.92). Willingness to disclose IPV in response to screening was higher in the postdisplay group for those with a personal IPV history (55% pre, 73% post; P = 0.02), African Americans (60% pre, 78% post; P = 0.02), and those with a high school degree or less education (66% pre, 77% post; P = 0.04). CONCLUSIONS: Intimate partner violence materials in this study were acceptable to most participants and did not negatively impact attitudes toward IPV screening or willingness to disclose IPV. Display of IPV materials should be considered as a component of IPV intervention. PMID- 29596283 TI - Pediatric Sigmoid Volvulus. AB - Sigmoid volvulus is an extremely rare cause of abdominal pain in children. More commonly seen in older adults, an SV occurs when a redundant loop of sigmoid wraps around its elongated, narrow mesentery causing obstruction and ischemia to the affected bowel segment. Children usually present with abdominal pain, nausea, and abdominal distension. Presentations may be acute or chronic with a history of episodic constipation or abdominal distension. The treatment plan includes an initial reduction of the volvulus via sigmoidoscopy with rectal biopsy to rule out Hirschsprung disease; however, operative management to remove the dilated sigmoid colon may be required in the setting of recurrence or confirmed Hirschsprung disease. Although rare, SV should be considered in a child presenting with abdominal pain as a missed diagnosis can have high potential morbidity and mortality. PMID- 29596284 TI - A Case of Wernicke Encephalopathy Developing After Ileal Bypass Surgery. AB - Wernicke encephalopathy is an acute neurological problem resulting from thiamine deficiency and manifesting with mental confusion, oculomotor dysfunction, and ataxia. It is associated with alcohol dependence in adults. Preparatory factors include hyperemesis gravidarum, prolonged diarrhea, prolonged parental nutrition without vitamin support, absorption disorders, anorexia, cancer, and chemotherapy. Failure to consider the clinical findings and preparatory factors of this disease, which is rare in children, can delay diagnosis. This report describes a case of Wernicke encephalopathy developing in a patient with brid ileus and receiving total parenteral nutrition after partial ileal bypass surgery. The patient's clinical and cranial magnetic resonance findings were compatible with Wernicke encephalopathy. Although these are not widespread, typical ocular findings for Wernicke encephalopathy were present. Dramatic improvements were observed in clinical, ocular, and cranial magnetic resonance findings after treatment. PMID- 29596285 TI - Rising Clinical Burden of Psychiatric Visits on the Pediatric Emergency Department. AB - OBJECTIVE: The mental health epidemic in pediatrics has resulted in a growing clinical burden on the health care system, including pediatric emergency departments (PED). Our objective was to describe the changing characteristics of visits to an urban PED, in particular length of stay, for emergency psychiatric evaluations (EPEs) over a 10-year period. METHODS: A retrospective study of children with an EPE in the PED at a large urban quaternary care children's hospital was performed during two discrete periods a decade apart: July 1, 2003 June 30, 2004 (period 1) and July 1, 2013-June 30, 2014 (period 2). Visit information, including length of stay and demographic data, were compared between groups. RESULTS: There was a significant increase in the percentage of PED visits for EPE from period 1 to period 2 (1.1% vs 2.2% P < 0.0001). Overall, the median (interquartile range [IQR]) length of stay for children requiring an EPE increased significantly for all visits (5.3 [3.2-15.4] hours vs 17.0 [6.0-26.0] hours, P < 0.0001), including for patients who were admitted (17.8 [7.4-24.6] hours vs 27.0 [21.0-36.0] hours, P < 0.0001) and for those who were discharged (4.5 [2.8-7.7] hours vs 8 [5-20] hours, P < 0.0001). CONCLUSIONS: Over a decade, the percentage of children with an EPE has doubled, with a significant increase in the amount of time spent in the PED. This highlights a continued surge in the utilization of PED resources for EPE. PMID- 29596286 TI - Acute Terminal Ileitis in Children: A Retrospective Study in Pediatric Emergency Department. AB - OBJECTIVES: This study aims to describe the clinical presentation and outcome of patients diagnosed with acute ileitis in our pediatric emergency department. METHODS: We performed a retrospective study of all patients diagnosed with terminal ileitis by abdominal ultrasonography findings in our pediatric emergency department, over the years 2013 and 2014. Patients with previous diagnosis of inflammatory bowel disease (IBD) were excluded. Data collected were clinical, radiological, and laboratory data at diagnosis; outcome including hospitalization care; and outpatient follow-up in pediatric gastroenterology and/or primary care. RESULTS: A total of 20 cases were retrieved and studied. All of them presented with abdominal pain, 65% located in the right lower quadrant. Leukocyte count, C reactive protein, and fibrinogen levels (means, 12,889; 4/MUL; 50.1 mg/L; and 575 mg/dL, respectively) were above normal range. Hemoglobin and platelet count were normal. A microbial cause of ileitis was found in 3 cases (Yersinia enterocolitica, Campylobacter jejuni, and Adenovirus). Nine patients were referred to a pediatric gastroenterology unit. No cases of IBD were found. CONCLUSIONS: Acute ileitis is a rare and benign cause of abdominal pain in the pediatric emergency department. The main intervention on initial assessment is to rule out potentially severe causes of abdominal pain that could benefit of an emergency surgical procedure. In contrast with adults and adolescents, acute ileitis in children does not have a clear association with development of IBD. PMID- 29596287 TI - Moments: Finding Passion and Purpose. PMID- 29596288 TI - Management of Intracranial Pressure: Part I: Pharmacologic Interventions. AB - Dangerous, sustained elevation in intracranial pressure (ICP) is a risk for any patient following severe brain injury. Intracranial pressure elevations that do not respond to initial management are considered refractory to treatment, or rICP. Patients are at significant risk of secondary brain injury and permanent loss of function resulting from rICP. Both nonpharmacologic and pharmacologic interventions are utilized to intervene when a patient experiences either elevation in ICP or rICP. In part 1 of this 2-part series, pharmacologic interventions are discussed. Opioids, sedatives, osmotic diuretics, hypertonic saline solutions, and barbiturates are drug classes that may be used in an attempt to normalize ICP and prevent secondary injury. Nursing care of these patients includes collaboration with an interprofessional team and is directed toward patient and family comfort. The utilization of an evidence-based guideline for the management of rICP is strongly encouraged to improve patient outcomes. PMID- 29596289 TI - Identification and Management of Acute Cardiac Tamponade. AB - Although incidence is rare, acute cardiac tamponade (CT) is a cardiovascular condition often resulting in a high mortality rate. In acute CT, rapid accumulation of fluid occurs in the pericardial sac and prevents the heart's chambers from adequately filling with blood, leading to reduced diastolic filling, diminished stroke volumes, and subsequent hemodynamic instability. Health care providers should be aware of at-risk patients and the earliest signs and symptoms because an acute CT is considered a medical emergency. PMID- 29596290 TI - Use of Recruitment Maneuvers in Patients With Acute Respiratory Distress Syndrome. AB - Acute respiratory distress syndrome (ARDS) is a deadly complication in critically ill patients that causes significant morbidity and mortality. Patients with ARDS are seen across intensive care unit settings, with treatment being largely supportive involving techniques through mechanical ventilation. Using low-tidal volume ventilation is a standard of practice for patients with ARDS, as a lung protection strategy; however, alveolar decruitment may occur. Recruitment maneuvers can recruit collapsed alveoli and promote oxygenation. There are several methods of recruitment maneuvers-each with varying levels and durations of positive end-expiratory pressure. It is still uncertain which method is the best. The evidence for the efficacy of recruitment maneuvers has shown a decrease in intensive care unit mortality, but strong evidence is lacking for its routine use, and the decision to use recruitment maneuvers should be based on individual characteristics and responses. This article reviews management of ARDS, recruitment maneuver techniques, and clinical application through a case study. PMID- 29596291 TI - Interprofessional Simulations Promote Knowledge Retention and Enhance Perceptions of Teamwork Skills in a Surgical-Trauma-Burn Intensive Care Unit Setting. AB - BACKGROUND: The current state of health care encompasses highly acute, complex patients, managed with ever-changing technology. The ability to function proficiently in critical care relies on knowledge, technical skills, and interprofessional teamwork. Integration of these factors can improve patient outcomes. Simulation provides "hands-on" practice and allows for the integration of teamwork into knowledge/skill training. However, simulation can require a significant investment of time, effort, and financial resources. The Institute of Medicine recommendations from 2015 include "strengthening the evidence base for interprofessional education (IPE)" and "linking IPE with changes in collaborative behavior." In one surgical-trauma-burn intensive care unit (STBICU), no IPE existed. The highly acute and diverse nature of the patients served by the unit highlights the importance of appropriate training. This is heightened during critical event situations where patients deteriorate rapidly and the team intervenes swiftly. PURPOSE: The aims of this study were to (1) evaluate knowledge retention and analyze changes in perceptions of teamwork among nurses and resident physicians in a STBICU setting after completion of an interprofessional critical event simulation and (2) provide insight for future interprofessional simulations (IPSs), including the ideal frequency of such training, associated cost, and potential effect on nursing turnover. DESIGN: A comparison-cohort pilot study was developed to evaluate knowledge retention and analyze changes in perceptions of teamwork. METHODS: A 1-hour critical event IPS was held for nurses and resident physicians in a STBICU setting. A traumatic brain injury patient with elevated intracranial pressure, rapid deterioration, and cardiac arrest was utilized for the simulation scenario. The simulation required the team to use interventions to reduce elevated intracranial pressure and then perform cardiac resuscitation according to Advanced Cardiac Life Support guidelines. A semistructured debriefing guided by the TENTS tool highlighted important aspects of teamwork. Participants took knowledge and Teamwork Skills Scale (TSS) pretests, posttests, and 1-month posttests. Mean scores were calculated for each time point (pre, post, and 1-month post), and paired t tests were used to evaluate changes. RESULTS: Mean knowledge test and TSS scores both significantly increased after the simulation and remained significantly elevated at 1-month follow-up. Participants recommended retraining intervals of 3 to 6 months. Cost of each simulation was estimated to be $324.44. Analysis of nursing turnover rates did not demonstrate a statistically significant reduction in turnover; however, confounding factors were not controlled for. CONCLUSION: Significant improvements on both knowledge test and TSS scores demonstrate the effectiveness of the intervention, and retention of the information gained and teamwork skills learned. Participants valued the intervention and recommended to increase the frequency of training. Future studies should develop a framework for "best practice" IPS, analyze the relationship with nursing turnover, and ultimately seek correlations between IPS and improved patient outcomes. PMID- 29596292 TI - Informing Leadership Models: Nursing and Organizational Characteristics of Neonatal Intensive Care Units in Freestanding Children's Hospitals. AB - BACKGROUND: Neonatal intensive care units (NICUs) located in freestanding children's hospitals may exhibit significant variation in nursing and organizational characteristics, which can serve as opportunities for collaboration to understand optimal staffing models and linkages to patient outcomes. OBJECTIVES: Adopting methods used by Hickey et al in pediatric cardiovascular critical care, the purpose of this study was to provide a foundational description of the nursing and organizational characteristics for NICUs located in freestanding children's hospitals in the United States. METHODS: Clinical nurse leaders in NICUs located in freestanding children's hospitals were invited to participate in an electronic cross-sectional survey. Descriptive analyses were used to summarize nursing and organizational characteristics. RESULTS: The response rate was 30% (13/43), with 69.2% of NICUs classified as level III/IV and 30.8% classified as level II/III. Licensed bed capacity varied significantly (range, 24-167), as did the proportion of full-time equivalent nurses (range, 71.78-252.3). Approximately three-quarters of staff nurses held baccalaureate degrees or higher. A quarter of nurses had 16 or more years (26.3%) of experience, and 36.9% of nurses had 11 or more years of nursing experience. Nearly one-third (29.2%) had 5 or less years of total nursing experience. Few nurses (10.6%) held neonatal specialty certification. All units had nurse educators, national and unit-based quality metrics, and procedural checklists. CONCLUSION: This study identified (1) variation in staffing models signaling an opportunity for collaboration, (2) the need to establish ongoing processes for sites to participate in future collaborative efforts, and (3) survey modifications necessary to ensure a more comprehensive understanding of nursing and organizational characteristics in freestanding children's hospital NICUs. PMID- 29596294 TI - Family Presence During Resuscitation: Physicians' Perceptions of Risk, Benefit, and Self-Confidence. AB - BACKGROUND: Families often desire proximity to loved ones during life-threatening resuscitations and perceive clear benefits to being present. However, critical care nurses and physicians perceive risks and benefits. Whereas research is accumulating on nurses' perceptions of family presence, physicians' perspectives have not been clearly explicated. Psychometrically sound measures of physicians' perceptions are needed to create new knowledge and enhance collaboration among critical care nurses and physicians during resuscitation events. OBJECTIVE: This study tests 2 new instruments that measure physicians' perceived risks, benefits, and self-confidence related to family presence during resuscitation. METHODS: By a correlational design, a convenience sample of physicians (N = 195) from diverse clinical specialties in 1 hospital in the United States completed the Physicians' Family Presence Risk-Benefit Scale and Physicians' Family Presence Self confidence Scale. RESULTS: Findings supported the internal consistency reliability and construct validity of both new scales. Mean scale scores indicated that physicians perceived more risk than benefit and were confident in managing resuscitations with families present, although more than two-thirds reported feeling anxious. Higher self-confidence was significantly related to more perceived benefit and less perceived risk (P = .001). Younger physicians, family practice physicians, and physicians who previously had invited family presence expressed more positive perceptions (P = .05-.001). DISCUSSION: These 2 new scales offer a means to assess key perceptions of physicians related to family presence. Further testing in diverse physician populations may further validate the scales and yield knowledge that can strengthen collaboration among critical care nurses and physicians and improve patient and family outcomes. PMID- 29596296 TI - Increasing Access to Palliative Care Services in the Intensive Care Unit. AB - BACKGROUND: The Institute of Medicine's report, Dying in America, highlights the critical need for the widespread implementation of palliative care to improve end of-life care. Approximately 20% of all deaths in America occur during or shortly after an intensive care unit (ICU) admission; therefore, it is important for critical care units to have systems in place to facilitate patient access to palliative care services. OBJECTIVES: The aim of this quality improvement (QI) project was to develop and implement a palliative care screening tool using evidence-based triggers to help increase the proportion of palliative care consultations in the ICU setting. METHODS: A QI project was designed and implemented in a 14-bed medical-surgical ICU in the southeastern United States using the Plan-Do-Study-Act cycle. A palliative care screening tool was developed by an interdisciplinary team of key stakeholders in the ICU using evidence-based triggers, and staff were educated on the intervention. The proportion of ICU patients who received a palliative care consultation was compared preintervention and postintervention to determine whether the QI project contributed to an increased proportion of palliative care consultations. RESULTS: The proportion of palliative care consultations among patients admitted to the ICU by the pulmonary critical care team increased from 1 of 10 preintervention to 3 of 10 postintervention, resulting in a promising increase in patients receiving palliative care services consistent with evidence-based recommendations. CONCLUSION: The use of an evidence-based screening tool to trigger palliative care consultation in the ICU setting can aid in increasing the proportion of critical care patients who receive a palliative care referral. The increase in the proportion of palliative care referrals by the pulmonary critical care service warrants expansion of the intervention to include additional medical subspecialists who frequently admit patients in this ICU setting. Further assessment of the intervention is warranted to determine whether the screening tool can aid in increasing palliative care consultations for more patients admitted to the hospital's ICU.

PMID- 29596298 TI - A Single-Center Retrospective Validation Study of the American College of Radiology Thyroid Imaging Reporting and Data System. AB - OBJECTIVE: This study aimed to evaluate a new risk stratification system, the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI RADS), published in 2017. MATERIALS AND METHODS: From January 2015 to December 2016, 1033 thyroid nodules in 1013 patients who had undergone sonography and thyroid surgery or fine-needle aspiration (FNA) in our hospital were included. The sonographic features were described in a standard manner and analyzed according to the white paper of the ACR TI-RADS Committee. Nodules were assigned points for each feature, and the points were totaled to determine the final TI RADS levels. RESULTS: Of the 1033 nodules, 725 were benign and 308 were malignant proven by operation or FNA. The malignant risk was associated with the composition, echogenicity, shape, margins, and echogenic foci of the nodules (P < 0.001). The calculated risk of malignancy was higher in nodules with macrocalcifications than those with peripheral calcifications, which is different from the ACR TI-RADS. The calculated malignancy rates of nodules with TR5, TR4, TR3, and TR2 were 67.1%, 13.0%, 1.1%, and 0%, respectively, which showed a higher malignant risk than the suggested threshold of TR5 in the ACR TI-RADS. Six nodules with TR4 recommended for no follow-up and 55 nodules with TR5 recommended for follow-up were malignant with cervical lymph node metastasis. CONCLUSIONS: The ACR TI-RADS provides effective malignancy risk stratification for thyroid nodules and was useful for the decision for FNA. However, the points assigned for echogenic foci, the set of the TI-RADS risk thresholds, and FNA thresholds may need more consideration and prospective validation. PMID- 29596299 TI - A Narrative Review on Contrast-Enhanced Ultrasound in Aortic Endograft Endoleak Surveillance. AB - Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography. However, color Doppler ultrasound can fail to detect as many as 31% of endoleaks. Contrast-enhanced ultrasound (CEUS) provides an alternative approach to excluded aneurysm sac follow-up imaging. The Society for Vascular Surgery notes a need for further research on the role of CEUS in endovascular aortic repair surveillance. The European Federation of Societies for Ultrasound in Medicine and Biology suggests that early results are promising. Meta-analyses report pooled sensitivities and specificities of CEUS compared with CTA for the detection of endoleak between 89% and 98% and 86% and 88%, respectively. Owing to the dynamic flow information it provides, CEUS may actually be more sensitive than CTA at detection and characterization in select circumstances. Challenges with adoption, patient selection, and operator dependency remain, but current and future research suggests a role for CEUS in endoleak surveillance. PMID- 29596300 TI - Quantitative Assessment of Thyroid, Submandibular, and Parotid Glands Elasticity With Shear-Wave Elastography in Children. AB - Tissue elasticity is becoming a more commonly used parameter in evaluation of parenchyma in inflammatory diseases. Considering the changes in the thyroid and salivary glands with adolescence, determination of mean elasticity ranges with a function of age is necessary to apply ultrasound elastography more widely in the pediatric population.The thyroid, submandibular, and parotid glands of 127 healthy volunteers (66 males, 61 females; mean age = 10.3 +/- 3.9 years; range = 3-17 years) were evaluated with shear-wave elastography.The mean elasticity values for the thyroid, submandibular, and parotid glands were 14.6 +/- 3.3, 11.8 +/- 2.2, and 11.8 +/- 2.6 kPa, respectively. There was a significant positive correlation between age and elasticity of the thyroid, submandibular, and parotid glands. There was a significant correlation between age and elasticity value of the thyroid gland adjusted for weight and height.This study provided the baseline quantitative elasticity measures of thyroid, submandibular, and parotid glands, which would be a reference for upcoming studies. In addition, an increase in elasticity value in thyroid gland as a function of age independent of change in weight and height was demonstrated. PMID- 29596301 TI - Superb Microvascular Imaging of Palatine Tonsils in Healthy Children: A Preliminary Study. AB - In healthy children, the normal vascularity index (VI) values were defined for palatine tonsils using the superb microvascular imaging (SMI), and the relationship with potential factors affecting these values was assessed. This prospective study evaluated 74 children (age range = 3-17 years, median = 13 years, SD = 6.4 years). The cases were divided into 3 subgroups based on age as 3 to 6 years (preschool), 7 to 12 years (school age), and 13 to 17 years (adolescent). Demographic data such as sex, age, and body mass index (BMI) were recorded. The VI values of tonsils were measured with SMI and power Doppler (PD), and the correlation with descriptive data was researched. The Student t test, Mann-Whitney U test, and Spearman rho correlation coefficient were used. The mean VI values on the right tonsil were calculated as 7.5% and 2.6% and on the left tonsil were 6.5% and 2.3% according to SMI and PD, respectively. On SMI, the vascularity was similar in the preschool and school-age groups, with a significant reduction between the school-age and adolescent groups. As BMI increased, tonsil vascularity reduced on SMI and PD. There was no significant difference in tonsil vascularity between the sexes. The VI values were identified to be higher on SMI compared with PD (P = 0.001). In healthy children, the normal VI values for both tonsils were determined with SMI and PD. On SMI, tonsil vascularity reduced significantly in the transition from school age to adolescence. Tonsil vascularity was affected by variations in BMI. PMID- 29596302 TI - Diagnosing a Strong-Fault Model by Conflict and Consistency. AB - The diagnosis method for a weak-fault model with only normal behaviors of each component has evolved over decades. However, many systems now demand a strong fault models, the fault modes of which have specific behaviors as well. It is difficult to diagnose a strong-fault model due to its non-monotonicity. Currently, diagnosis methods usually employ conflicts to isolate possible fault and the process can be expedited when some observed output is consistent with the model's prediction where the consistency indicates probably normal components. This paper solves the problem of efficiently diagnosing a strong-fault model by proposing a novel Logic-based Truth Maintenance System (LTMS) with two search approaches based on conflict and consistency. At the beginning, the original a strong-fault model is encoded by Boolean variables and converted into Conjunctive Normal Form (CNF). Then the proposed LTMS is employed to reason over CNF and find multiple minimal conflicts and maximal consistencies when there exists fault. The search approaches offer the best candidate efficiency based on the reasoning result until the diagnosis results are obtained. The completeness, coverage, correctness and complexity of the proposals are analyzed theoretically to show their strength and weakness. Finally, the proposed approaches are demonstrated by applying them to a real-world domain-the heat control unit of a spacecraft-where the proposed methods are significantly better than best first and conflict directly with A* search methods. PMID- 29596303 TI - Phasor-Based Endogenous NAD(P)H Fluorescence Lifetime Imaging Unravels Specific Enzymatic Activity of Neutrophil Granulocytes Preceding NETosis. AB - Time-correlated single-photon counting combined with multi-photon laser scanning microscopy has proven to be a versatile tool to perform fluorescence lifetime imaging in biological samples and, thus, shed light on cellular functions, both in vitro and in vivo. Here, by means of phasor-analyzed endogenous NAD(P)H (nicotinamide adenine dinucleotide (phosphate)) fluorescence lifetime imaging, we visualize the shift in the cellular metabolism of healthy human neutrophil granulocytes during phagocytosis of Staphylococcus aureus pHrodoTM beads. We correlate this with the process of NETosis, i.e., trapping of pathogens by DNA networks. Hence, we are able to directly show the dynamics of NADPH oxidase activation and its requirement in triggering NETosis in contrast to other pathways of cell death and to decipher the dedicated spatio-temporal sequence between NADPH oxidase activation, nuclear membrane disintegration and DNA network formation. The endogenous FLIM approach presented here uniquely meets the increasing need in the field of immunology to monitor cellular metabolism as a basic mechanism of cellular and tissue functions. PMID- 29596305 TI - Differences in the Effects of EGCG on Chromosomal Stability and Cell Growth between Normal and Colon Cancer Cells. AB - The tea catechin epigallocatechin-3-gallate (EGCG) proved to be the most potent physiologically active tea compound in vitro. It possesses antioxidant as well as pro-oxidant properties. EGCG has the effect of inducing apoptosis of tumor cells and inhibiting cell proliferation. Whether this effect is associated with the antioxidant or pro-oxidative effects of EGCG affecting the genome stability of normal and cancer cells has not been confirmed. Here, we selected Human normal colon epithelial cells NCM460 and colon adenocarcinoma cells COLO205 to investigate the effects of EGCG (0–40 μg/mL) on the genome stability and cell growth status. Chromosomal instability (CIN), nuclear division index (NDI), and apoptosis was measured by cytokinesis-block micronucleus assay (CBMN), and the expression of core genes in mismatch repair (hMLMLH1 and hMSH2) was examined by RT-qPCR. We found that EGCG significantly reduced CIN and apoptosis rate of NCM460 at all concentrations (5–40 μg/mL) and treatment time, EGCG at 5 μg/mL promoted cell division; EGCG could significantly induce chromosome instability in COLO205 cells and trigger apoptosis and inhibition of cell division. These results suggest that EGCG exhibits different genetic and cytological effects in normal and colon cancer cells. PMID- 29596306 TI - Use of Iodine-Containing Dietary Supplements Remains Low among Women of Reproductive Age in the United States: NHANES 2011-2014. AB - In the United States, the American Thyroid Association recommends that women take a dietary supplement containing 150 µg of iodine 3 months prior to conception and while pregnant and lactating to support fetal growth and neurological development. We used data from the National Health and Nutrition Examination Survey 2011–2014 to describe the use of dietary supplements with and without iodine in the past 30 days among 2155 non-pregnant, non lactating (NPNL) women; 122 pregnant women; and 61 lactating women. Among NPNL women, 45.3% (95% Confidence Interval [CI]: 42.0, 48.6) used any dietary supplement and 14.8% (95% CI: 12.7, 16.8) used a dietary supplement with iodine in the past 30 days. Non-Hispanic black and Hispanic women were less likely to use any dietary supplement as well as one with iodine, than non-Hispanic white or non-Hispanic Asian women (p < 0.05). Among pregnant women, 72.2% (95% CI: 65.8, 78.6) used any dietary supplement; however, only 17.8% (95% CI: 11.4, 24.3) used a dietary supplement with iodine. Among lactating women, 75.0% (95% CI: 63.0, 87.0) used a dietary supplement; however, only 19.0% (95% CI: 8.8, 29.2) used a dietary supplement with iodine. Among NPNL women using a supplement with iodine, median daily iodine intake was 75.0 µg. Self-reported data suggests that the use of iodine containing dietary supplements among pregnant and lactating women remains low in contrast with current recommendations. PMID- 29596304 TI - Regulating Cdc42 and Its Signaling Pathways in Cancer: Small Molecules and MicroRNA as New Treatment Candidates. AB - Despite great improvements in the diagnosis and treatment of neoplasms, metastatic disease is still the leading cause of death in cancer patients, with mortality rates still rising. Given this background, new ways to treat cancer will be important for development of improved cancer control strategies. Cdc42 is a member of the Rho GTPase family and plays an important role in cell-to-cell adhesion, formation of cytoskeletal structures, and cell cycle regulation. It thus influences cellular proliferation, transformation, and homeostasis, as well as the cellular migration and invasion processes underlying tumor formation. Cdc42 acts as a collection point for signal transduction and regulates multiple signaling pathways. Moreover, recent studies show that in most human cancers Cdc42 is abnormally expressed and promoting neoplastic growth and metastasis. Regarding possible new treatments for cancer, miRNA and small molecules targeting Cdc42 and related pathways have been recently found to be effective on cancer. In this review, we analyze the newly recognized regulation mechanisms for Cdc42 and Cdc42-related signal pathways, and particularly new treatments using small molecules and miRNAs to inhibit the abnormal overexpression of Cdc42 that may slow down the metastasis process, improve cancer therapy and lead to novel strategies for development of antineoplastic drugs. PMID- 29596307 TI - Resistance Training Prevents Muscle Loss Induced by Caloric Restriction in Obese Elderly Individuals: A Systematic Review and Meta-Analysis. AB - It remains unclear as to what extent resistance training (RT) can attenuate muscle loss during caloric restriction (CR) interventions in humans. The objective here is to address if RT could attenuate muscle loss induced by CR in obese elderly individuals, through summarized effects of previous studies. Databases MEDLINE, Embase and Web of Science were used to perform a systematic search between July and August 2017. Were included in the review randomized clinical trials (RCT) comparing the effects of CR with (CRRT) or without RT on lean body mass (LBM), fat body mass (FBM), and total body mass (BM), measured by dual-energy X-ray absorptiometry, on obese elderly individuals. The six RCTs included in the review applied RT three times per week, for 12 to 24 weeks, and most CR interventions followed diets of 55% carbohydrate, 15% protein, and 30% fat. RT reduced 93.5% of CR-induced LBM loss (0.819 kg [0.364 to 1.273]), with similar reduction in FBM and BM, compared with CR. Furthermore, to address muscle quality, the change in strength/LBM ratio tended to be different (p = 0.07) following CRRT (20.9 ± 23.1%) and CR interventions (−7.5 ± 9.9%). Our conclusion is that CRRT is able to prevent almost 100% of CR-induced muscle loss, while resulting in FBM and BM reductions that do not significantly differ from CR. PMID- 29596309 TI - Risk Factors for Brachial Plexus Birth Injury. AB - Over the course of decades, the incidence of brachial plexus birth injury (BPBI) has increased despite advances in healthcare which would seem to assist in decreasing the rate. The aim of this study is to identify previously unknown risk factors for BPBI and the risk factors with potential to guide preventative measures. A case control study of 52 mothers who had delivered a child with a BPBI injury and 132 mothers who had delivered without BPBI injury was conducted. Univariate, multivariable and logistic regressions identified risk factors and their combinations. The odds of BPBI were 2.5 times higher when oxytocin was used and 3.7 times higher when tachysystole occurred. The odds of BPBI injury are increased when tachysystole and oxytocin occur during the mother's labor. Logistic regression identified a higher risk for BPBI when more than three of the following variables (>30 lbs gained during the pregnancy, stage 2 labor >61.5 min, mother's age >26.4 years, tachysystole, or fetal malpresentation) were present in any combination.

AB - Mitochondrial respiratory chain (MRC) disorders have a multifaceted clinical presentation and genetic origin[...]. PMID- 29596308 TI - EP4 as a Therapeutic Target for Aggressive Human Breast Cancer. AB - G-protein-coupled receptors (GPCRs, also called seven-transmembrane or heptahelical receptors) are a superfamily of cell surface receptor proteins that bind to many extracellular ligands and transmit signals to an intracellular guanine nucleotide-binding protein (G-protein). When a ligand binds, the receptor activates the attached G-protein by causing the exchange of Guanosine-5' triphosphate (GTP) for guanosine diphosphate (GDP). They play a major role in many physiological functions, as well as in the pathology of many diseases, including cancer progression and metastasis. Only a few GPCR members have been exploited as targets for developing drugs with therapeutic benefit in cancer. Present review briefly summarizes the signaling pathways utilized by the EP (prostaglandin E receptor) family of GPCR, their physiological and pathological roles in carcinogenesis, with special emphasis on the roles of EP4 in breast cancer progression. We make a case for EP4 as a promising newer therapeutic target for treating breast cancer. We show that an aberrant over-expression of cyclooxygenase (COX)-2, which is an inflammation-associated enzyme, occurring in 40-50% of breast cancer patients leads to tumor progression and metastasis due to multiple cellular events resulting from an increased prostaglandin (PG) E2 production in the tumor milieu. They include inactivation of host anti-tumor immune cells, such as Natural Killer (NK) and T cells, increased immuno suppressor function of tumor-associated macrophages, promotion of tumor cell migration, invasiveness and tumor-associated angiogenesis, due to upregulation of multiple angiogenic factors including Vascular Endothelial Growth Factor (VEGF) A, increased lymphangiogenesis (due to upregulation of VEGF-C/D), and a stimulation of stem-like cell (SLC) phenotype in cancer cells. All of these events were primarily mediated by activation of the Prostaglandin (PG) E receptor EP4 on tumor or host cells. We show that selective EP4 antagonists (EP4A) could mitigate all of these events tested with cells in vitro as well as in vivo in syngeneic COX-2 expressing mammary cancer bearing mice or immune-deficient mice bearing COX-2 over-expressing human breast cancer xenografts. We suggest that EP4A can avoid thrombo-embolic side effects of long term use of COX-2 inhibitors by sparing cardio-protective roles of PGI2 via IP receptor activation or PGE2 via EP3 receptor activation. Furthermore, we identified two COX-2/EP4 induced oncogenic and SLC-stimulating microRNAs-miR526b and miR655, one of which (miR655) appears to be a potential blood biomarker in breast cancer patients for monitoring SLC-ablative therapies, such as with EP4A. We suggest that EP4A will likely produce the highest benefit in aggressive breast cancers, such as COX-2 expressing triple-negative breast cancers, when combined with other newer agents, such as inhibitors of programmed cell death (PD)-1 or PD-L1. PMID- 29596311 TI - The Effects of Isoflavone Supplementation Plus Combined Exercise on Lipid Levels, and Inflammatory and Oxidative Stress Markers in Postmenopausal Women. AB - This study tested the effect of isoflavone supplementation in addition to combined exercise training on plasma lipid levels, inflammatory markers and oxidative stress in postmenopausal women. Thirty-two healthy and non-obese postmenopausal women without hormone therapy were randomly assigned to exercise + placebo (PLA; n = 15) or exercise + isoflavone supplementation (ISO; n = 17) groups. They performed 30 sessions of combined exercises (aerobic plus resistance) over ten weeks and consumed 100 mg of isoflavone supplementation or placebo. Blood samples were collected after an overnight fast to analyze the lipid profile, interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), total antioxidant capacity (FRAP), and thiobarbituric acid reactive substances (TBARS), before and after ten weeks of the intervention. There were no differences in the changes (pre vs. post) between groups for any of the inflammatory markers, oxidative stress markers or lipid profile variables. However, interleukin-8 was different between pre- and post-tests (p < 0.001) in both groups (Δ = 7.61 and 5.61 pg/mL) as were cholesterol levels (p < 0.05), with no interaction between groups. The combination of isoflavone supplementation and exercise training did not alter oxidative stress markers in postmenopausal women, but exercise training alone may increase IL-8 and decrease total cholesterol levels. PMID- 29596312 TI - Physical Activity as a Determinant of Quality of Life in Working-Age People in Wroclaw, Poland. AB - Regular physical activity can greatly contribute to the improvement of physical fitness and performance, reduction of the incidence risk of some occupational diseases, and as a consequence, to a general improvement of quality of life in terms of health status. The aim of the article was to assess relationships between the quality of life and physical activity of a working-age population. The study material comprised 4460 residents of the city of Wroclaw, Poland (2129 men, 2331 women) aged 18-64 years. The study was a questionnaire survey using the International Physical Activity Questionnaire Short Form (IPAQ-SF) and The World Health Organization Quality of Life (WHOQOL-BREF) questionnaires. The highest levels of overall quality of life and its four particular domains (physical, psychological, social, and environmental), as well as perceived health conditions were found among the most physically active respondents. Furthermore, the odds of high assessment of perceived overall quality of life were shown to increase with the increasing levels of physical activity. Activities aimed at the improvement of the quality of life of working-age people should involve programs enhancing the development of physical activity. PMID- 29596313 TI - Relationship between Nutritional Status and Gastrointestinal Symptoms in Geriatric Patients with End-Stage Renal Disease on Dialysis. AB - Gastrointestinal symptoms (GIS) are common in patients with end-stage renal disease (ESRD) and are associated with nutritional risks resulting from low food intake. Little is known about the relationship between GIS and malnutrition in geriatric patients with ESRD. The main objective of this study was to determine the relationship between nutritional status and severity of GIS in geriatric patients on dialysis therapy. Clinically-stable geriatric patients (older than 60 years old) who were dialysis outpatients were included in this cross-sectional study. The severity of GIS was assessed using the Gastrointestinal Symptoms Questionnaire (GSQ, short version), with patients classified into three groups: mild, moderate, and severe. Nutritional status was evaluated with the Malnutrition Inflammation Score (MIS), anthropometric assessment, biochemical parameters, and bioelectrical impedance. Descriptive statistics were used and differences between groups were analyzed with ANOVA and Kruskal Wallis, with a p < 0.05 considered to indicate significance. Fifty patients completed the study; the median age was 67 years old. Twenty-three patients were on hemodialysis (HD) and 27 were on peritoneal dialysis (PD). No significant differences were found according to dialysis modality, presence of diabetes, or gender. Ninety percent of patients had at least one GIS. Poorer nutritional status (evaluated by MIS) was related to a higher severity of GIS. There were no significant differences with other nutritional parameters. Our study showed a high prevalence of GIS in geriatric patients. There were no differences in observed GIS values that were attributed to dialysis modality, gender, or presence of type 2 diabetes mellitus (DM2). Severe GIS values were associated with poorer nutritional status determined by MIS, however, there was no association with anthropometry, biochemical values, or bioimpedance vector analysis. PMID- 29596314 TI - Betaine in Cereal Grains and Grain-Based Products. AB - Betaine is a non-essential nutrient which performs several important physiological functions in organisms. Abundant data exist to suggest that betaine has a potential for prevention of chronic diseases and that its dietary intake may contribute to overall health enhancement. Several studies have pointed out that the betaine status of the general population is inadequate and have suggested nutritional strategies to improve dietary intake of betaine. Cereal based food has been implicated as the major source of betaine in the Western diet. This review summarizes the results on the betaine content in various cereals and related products. Attention has been given to the betaine content in gluten-free grains and products. It also discusses the stability of betaine during processing (cooking, baking, extrusion) and possibilities to increase betaine content by fortification. PMID- 29596315 TI - Core Level Spectra of Organic Molecules Adsorbed on Graphene. AB - We perform first principle calculations based on density functional theory to investigate the effect of the adsorption of core-excited organic molecules on graphene. We simulate Near Edge X-ray absorption Fine Structure (NEXAFS) and X ray Photoemission Spectroscopy (XPS) at the N and C edges for two moieties: pyridine and the pyridine radical on graphene, which exemplify two different adsorption characters. The modifications of molecular and graphene energy levels due to their interplay with the core-level excitation are discussed. We find that upon physisorption of pyridine, the binding energies of graphene close to the adsorption site reduce mildly, and the NEXAFS spectra of the molecule and graphene resemble those of gas phase pyridine and pristine graphene, respectively. However, the chemisorption of the pyridine radical is found to significantly alter these core excited spectra. The C 1s binding energy of the C atom of graphene participating in chemisorption increases by ~1 eV, and the C atoms of graphene alternate to the adsorption site show a reduction in the binding energy. Analogously, these C atoms also show strong modifications in the NEXAFS spectra. The NEXAFS spectrum of the chemisorbed molecule is also modified as a result of hybridization with and screening by graphene. We eventually explore the electronic properties and magnetism of the system as a core-level excitation is adiabatically switched on. PMID- 29596316 TI - Review on PACAP-Induced Transcriptomic and Proteomic Changes in Neuronal Development and Repair. AB - Pituitary adenylate cyclase activating polypeptide (PACAP) is a neuropeptide with widespread occurrence and diverse biological effects. Among its several different effects, of special importance is the action of PACAP on neuronal proliferation, differentiation and migration, and neuroprotection. The neuroprotective mechanism of PACAP is both direct and indirect, via neuronal and non-neuronal cells. Several research groups have performed transcriptomic and proteomic analysis on PACAP-mediated genes and proteins. Hundreds of proteins have been described as being involved in the PACAP-mediated neuroprotection. In the present review we summarize the few currently available transcriptomic data potentially leading to the proteomic changes in neuronal development and protection. Proteomic studies focusing on the neuroprotective role of PACAP are also reviewed and discussed in light of the most intriguing and promising effect of this neuropeptide, which may possibly have future therapeutic potential. PMID- 29596318 TI - Dietary Cholesterol, Serum Lipids, and Heart Disease: Are Eggs Working for or Against You? AB - The relationship between blood cholesterol and heart disease is well-established, with the lowering of serum low-density lipoprotein (LDL)-cholesterol being the primary target of preventive therapy. Furthermore, epidemiological studies report lower risk for heart disease with higher concentrations of high-density lipoprotein (HDL)-cholesterol. There has also been considerable interest in studying the relationship between dietary cholesterol intake and heart disease risk. Eggs are one of the richest sources of cholesterol in the diet. However, large-scale epidemiological studies have found only tenuous associations between the intake of eggs and cardiovascular disease risk. Well-controlled, clinical studies show the impact of dietary cholesterol challenges via egg intake on serum lipids is highly variable, with the majority of individuals (~2/3 of the population) having only minimal responses, while those with a significant response increase both LDL and HDL-cholesterol, typically with a maintenance of the LDL/HDL cholesterol ratio. Recent drug trials targeting HDL-cholesterol have been unsuccessful in reducing cardiovascular events, and thus it is unclear if raising HDL-cholesterol with chronic egg intake is beneficial. Other important changes with egg intake include potentially favorable effects on lipoprotein particle profiles and enhancing HDL function. Overall, the increased HDL cholesterol commonly observed with dietary cholesterol feeding in humans appears to also coincide with improvements in other markers of HDL function. However, more investigation into the effects of dietary cholesterol on HDL functionality in humans is warranted. There are other factors found in eggs that may influence risk for heart disease by reducing serum lipids, such as phospholipids, and these may also modify the response to dietary cholesterol found in eggs. In this review, we discuss how eggs and dietary cholesterol affect serum cholesterol concentrations, as well as more advanced lipoprotein measures, such as lipoprotein particle profiles and HDL metabolism.

AB - Feline injection site sarcomas (FISS) are malignant skin tumors with high recurrence rates despite the primary treatment of radical surgical resections. Adjunctive radiotherapy or chemotherapy with doxorubicin is mostly ineffective. Cellular and molecular causes of multidrug resistance, specific physio-chemical properties of solid tumors impairing drug transport, and the tumor microenvironment have been indicated for causing standard chemotherapy failure. Gold nanoparticles are promising imaging tools, nanotherapeutics, and drug delivery systems (DDS) for chemotherapeutics, improving drug transport within solid tumors. This study was conducted to assess the distribution of 4-nm glutathione-stabilized gold nanoparticles in FISS and their influence on kidney and liver parameters in nude mice. The role of gold nanoparticles as a doxorubicin DDS in FISS was examined to determine the potential reasons for failure to translate results from in vitro to in vivo studies. Grade III tumors characterized by a large area of necrosis at their core displayed positive immuneexpression of tumor-associated macrophages (TAM) at both the periphery and within the tumor core near the area of necrosis. Gold nanoparticles did not cause necrosis at the injection site and had no negative effect on liver and kidney parameters in nude mice. Gold nanoparticles accumulated in the tumor core and at the periphery and co-internalized with TAM-an important observation and potential therapeutic target warranting further investigation. The large area of necrosis and high immunoexpression of TAM, indicating "pro-tumor macrophages", may be responsible for FISS tumor progression and therapeutic failure. However, further studies are required to test this hypothesis.

AB - The aims of this study were (i) to evaluate the growth kinetic of L. paracasei LBC 81 in fermented milks enriched with green banana pulp (GBP); (ii) to evaluate the effect of the incorporation of GBP on the chemical composition and the sensory acceptance; and (iii) to study the viability of the probiotic and technological properties during refrigerated storage. The amount of GBP used were 3.0, 6.0 and 9.0 g/100 g. The results show that the higher the concentration of GBP added, the shorter the time taken to reach pH 4.6. It was observed that the incorporation of GBP did not affect negatively the viability of L. paracasei LBC 81 during storage. The fermented milk elaborated with 6.0 g/100 g of GBP was the most accepted. The present study indicates that the enrichment of fermented milk with GBP favors the stability of the probiotic strain, L. paracasei LBC 81 during storage. PMID- 29596320 TI - A Review of Selective Laser Melted NiTi Shape Memory Alloy. AB - NiTi shape memory alloys (SMAs) have the best combination of properties among the different SMAs. However, the limitations of conventional manufacturing processes and the poor manufacturability of NiTi have critically limited its full potential applicability. Thus, additive manufacturing, commonly known as 3D printing, has the potential to be a solution in fabricating complex NiTi smart structures. Recently, a number of studies on Selective Laser Melting (SLM) of NiTi were conducted to explore the various aspects of SLM-produced NiTi. Compared to producing conventional metals through the SLM process, the fabrication of NiTi SMA is much more challenging. Not only do the produced parts require a high density that leads to good mechanical properties, strict composition control is needed as well for the SLM NiTi to possess suitable phase transformation characteristics. Additionally, obtaining a good shape memory effect from the SLM NiTi samples is another challenging task that requires further understanding. This paper presents the results of the effects of energy density and SLM process parameters on the properties of SLM NiTi. Its shape memory properties and potential applications were then reviewed and discussed. PMID- 29596321 TI - Transcriptomic Analysis of Gonadal Adipose Tissue in Male Mice Exposed Perinatally to 2,2',4,4'-Tetrabromodiphenyl Ether (BDE-47). AB - For the majority of lipophilic compounds, adipose tissue is traditionally considered as a storage depot and only rarely as a target organ. Meanwhile, abnormalities in adipose tissue physiology induced by chemical exposure may contribute to the current epidemic of obesity and metabolic diseases. Polybrominated diphenyl ethers (PBDEs) are a group of lipophilic flame retardants found in the majority of human samples in North America. Their ability to alter the physiology of adipose tissue is unknown. We exposed pregnant mice to 0.2 mg/kg body weight/day of BDE-47 perinatally. Transcriptomic changes in gonadal adipose tissue were analyzed in male offspring using the RNA-seq approach with subsequent bioinformatic analysis. The expression of genes of coagulation and complement cascade, de novo lipogenesis, and xenobiotic metabolism was altered in response to BDE-47 exposure. The affected molecular network included the following hubs: PPARalpha, HNF1A, and HNF4. These findings suggest that adipose tissue should be considered a target tissue for BDE-47, in addition to its role as a storage depot. This study also builds a background for a targeted search of sensitive phenotypic endpoints of BDE-47 exposure, including lipid profile parameters and coagulation factors in circulation. Additional studies are needed to investigate the role of PBDEs as an obesogen. PMID- 29596322 TI - Development of Polyclonal Antibody against Clenbuterol for Immunoassay Application. AB - Development of an immunoassay for clenbuterol (CLB) detection required an anti CLB antibody as an important bioreceptor. In this study, we report our work on production and purification of a rabbit-derived polyclonal anti-CLB antibody. The antibody was then purified by nProtein A Sepharose affinity column and the antibody purity was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis. The activities of purified antibody were evaluated based on high antibody titer determined from enzyme-linked immunosorbent assay (ELISA). The sensitivity and selectivity of this antibody was evaluated and exhibits negligible cross-reactivity to antibiotics other than beta agonist families. Evaluation of the antibody as bioreceptor in immunoassay was performed using direct competitive ELISA and exhibited linear calibration plot (R2 = 0.9484). The antibody was used to detect the content of CLB in spiked milk samples and the recovery of more than 92% indicating significant performance as bioreceptor for the development of a rapid and simple immunoassay. PMID- 29596323 TI - Biofunctionalized Scaffold in Bone Tissue Repair. AB - Bone tissue engineering is based on bone grafting to repair bone defects. Bone graft substitutes can contribute to the addition of mesenchymal stem cells (MSCs) in order to enhance the rate and the quality of defect regeneration. The stem cell secretome contains many growth factors and chemokines, which could affect cellular characteristics and behavior. Conditioned medium (CM) could be used in tissue regeneration avoiding several problems linked to the direct use of MSCs. In this study, we investigated the effect of human periodontal ligament stem cells (hPDLSCs) and their CM on bone regeneration using a commercially available membrane scaffold Evolution (EVO) implanted in rat calvarias. EVO alone or EVO + hPDLSCs with or without CM were implanted in Wistar male rats subjected to calvarial defects. The in vivo results revealed that EVO membrane enriched with hPDLSCs and CM showed a better osteogenic ability to repair the calvarial defect. These results were confirmed by acquired micro-computed tomography (CT) images and the increased osteopontin levels. Moreover, RT-PCR in vitro revealed the upregulation of three genes (Collagen (COL)5A1, COL16A1 and transforming growth factor (TGF)beta1) and the down regulation of 26 genes involved in bone regeneration. These results suggest a promising potential application of CM from hPDLSCs and scaffolds for bone defect restoration and in particular for calvarial repair in case of trauma. PMID- 29596324 TI - Camelid Single-Domain Antibodies (VHHs) against Crotoxin: A Basis for Developing Modular Building Blocks for the Enhancement of Treatment or Diagnosis of Crotalic Envenoming. AB - Toxic effects triggered by crotalic envenoming are mainly related to crotoxin (CTX), composed of a phospholipase A2 (CB) and a subunit with no toxic activity (CA). Camelids produce immunoglobulins G devoid of light chains, in which the antigen recognition domain is called VHH. Given their unique characteristics, VHHs were selected using Phage Display against CTX from Crotalus durissus terrificus. After three rounds of biopanning, four sequence profiles for CB (KF498602, KF498603, KF498604, and KF498605) and one for CA (KF498606) were revealed. All clones presented the VHH hallmark in FR2 and a long CDR3, with the exception of KF498606. After expressing pET22b-VHHs in E. coli, approximately 2 to 6 mg of protein per liter of culture were obtained. When tested for cross reactivity, VHHs presented specificity for the Crotalus genus and were capable of recognizing CB through Western blot. KF498602 and KF498604 showed thermostability, and displayed affinity constants for CTX in the micro or nanomolar range. They inhibited in vitro CTX PLA2 activity, and CB cytotoxicity. Furthermore, KF498604 inhibited the CTX-induced myotoxicity in mice by 78.8%. Molecular docking revealed that KF498604 interacts with the CA–CB interface of CTX, seeming to block substrate access. Selected VHHs may be alternatives for the crotalic envenoming treatment. PMID- 29596325 TI - Preconditioning-Like Properties of Short-Term Hypothermia in Isolated Perfused Rat Liver (IPRL) System. AB - Hypothermia may attenuate the progression of ischemia-induced damage in liver. Here, we determined the effects of a brief cycle of hypothermic preconditioning applied before an ischemic/reperfusion (I/R) episode in isolated perfused rat liver (IPRL) on tissue damage and oxidative stress. Rats (male, 200-250 g) were anaesthetised with sodium pentobarbital (60 mg.kg-1 i.p) and underwent laparatomy. The liver was removed and perfused in a temperature-regulated non recirculating system. Livers were randomly divided into two groups (n = 6 each group). In the hypothermia-preconditioned group, livers were perfused with hypothermic buffer (cycle of 10 min at 22 degrees C plus 10 min at 37 degrees C) and the other group was perfused at 37 degrees C. Both groups were then submitted to 40 min of warm ischemia and 20 min of warm reperfusion. The level of tissue-damage indicators (alanine amino transferase, ALT; lactate dehydrogenase, LDH; and proteins), oxidative stress markers (thiobarbituric acid-reactive substances, TBARS; advanced oxidation protein products, AOPP; and glutathione, GSH) were measured in aliquots of perfusate sampled at different time intervals. Histological determinations and oxidative stress biomarkers in homogenized liver (AOPP; TBARS; nitric oxide derivatives, NOx; GSH and glutathione disulphide, GSSG) were also made in the tissue at the end. Results showed that both damage and oxidant indicators significantly decreased while antioxidant increased in hypothermic preconditioned livers. In addition, homogenized liver determinations and histological observations at the end of the protocol corroborate the results in the perfusate, confirming the utility of the perfusate as a non-invasive method. In conclusion, hypothermic preconditioning attenuates oxidative damage and appears to be a promising strategy to protect the liver against IR injury. PMID- 29596326 TI - Differentiation Therapy Targeting the beta-Catenin/CBP Interaction in Pancreatic Cancer. AB - BACKGROUND: Although canonical Wnt signaling is known to promote tumorigenesis in pancreatic ductal adenocarcinoma (PDAC), a cancer driven principally by mutant K Ras, the detailed molecular mechanisms by which the Wnt effector beta-catenin regulates such tumorigenesis are largely unknown. We have previously demonstrated that beta-catenin's differential usage of the Kat3 transcriptional coactivator cyclic AMP-response element binding protein-binding protein (CBP) over its highly homologous coactivator p300 increases self-renewal and suppresses differentiation in other types of cancer. AIM/METHODS: To investigate Wnt-mediated carcinogenesis in PDAC, we have used the specific small molecule CBP/beta-catenin antagonist, ICG-001, which our lab identified and has extensively characterized, to examine its effects in human pancreatic cancer cells and in both an orthotopic mouse model and a human patient-derived xenograft (PDX) model of PDAC. RESULTS/CONCLUSION: We report for the first time that K-Ras activation increases the CBP/beta-catenin interaction in pancreatic cancer; and that ICG-001 specific antagonism of the CBP/beta-catenin interaction sensitizes pancreatic cancer cells and tumors to gemcitabine treatment. These effects were associated with increases in the expression of let-7a microRNA; suppression of K-Ras and survivin; and the elimination of drug-resistant cancer stem/tumor-initiating cells. PMID- 29596328 TI - Performance of the Adult ADHD Self-Report Scale-v1.1 in Adults with Major Depressive Disorder. AB - Attention deficit/hyperactivity disorder (ADHD) is an under-recognized comorbid disorder among patients with mood disorders. ADHD is an independent risk factor for suicidal ideation and behavior and contributes to many aspects of impaired function in adults. Diagnosis of ADHD in Major Depressive Disorder (MDD) patients is challenging due to the overlap in cognitive symptoms between the two disorders. The ADHD Self-Report Scale, version 1.1 (ASRS-v1.1) is a widely used screening instrument for ADHD in adults but its accuracy has not been evaluated previously in treatment-seeking MDD patients. We administered the ASRS-v1.1 to 55 healthy controls and 40 adults with a primary psychiatric diagnosis of MDD who were participating in clinical research studies. ADHD diagnosis was assessed via structured interview with the adult ADHD module of the Mini International Neuropsychiatric Interview Plus version 6.0.0 (MINI) along with a psychiatrist's assessment. Overall, full-syndrome ADHD was diagnosed in 12.5% of the MDD patients. MDD patients endorsed all 18 items of the ASRS-v1.1 more frequently than the healthy controls and the number of ASRS-v1.1 items endorsed correlated with levels of anxiety in the MDD patients. The ASRS-v1.1 demonstrated fair performance for identifying full syndrome DSM-IV ADHD diagnosis, with sensitivity 60%, specificity: 68.6%, positive predictive value 21.4%, negative predictive value 92.3% and total classification accuracy of 67.5%. Positive predictive value improved substantially when the ADHD criterion requiring symptom onset before age 7 was omitted. In adult MDD patients, a negative ASRS-v1.1 screen strongly suggests the absence of ADHD but positive screen results require careful evaluation to determine whether self-reported ADHD symptoms simply emerge from depression or whether comorbid ADHD is present. PMID- 29596327 TI - Disruption of PTPS Gene Causing Pale Body Color and Lethal Phenotype in the Silkworm, Bombyx mori. AB - Phenylketonuria (PKU) is an inborn error of metabolism caused by mutations in the phenylalanine hydroxylase (PAH) gene or by defects in the tetrahydrobiopterin (BH4) synthesis pathway. Here, by positional cloning, we report that the 6 pyruvoyl-tetrahydropterin synthase (PTPS) gene, encoding a key enzyme of BH4 biosynthesis, is responsible for the alc (albino C) mutation that displays pale body color, head shaking, and eventually lethality after the first molting in silkworm. Compared to wild type, the alc mutant produced more substrates (phenylalanine (Phe) and tyrosine (Tyr)) and generated less DOPA and dopamine. Application of 2,4-diamino-6-hydroxypyrimidine (DAHP) to block BH4 synthesis in the wild type effectively produced the alc-like phenotype, while BH4 supplementation rescued the defective body color and lethal phenotype in both alc and DAHP-treated individuals. The detection of gene expressions and metabolic substances after drugs treatments in alc and normal individuals imply that silkworms and humans have a high similarity in the drugs metabolic features and the gene pathway related to BH4 and the dopamine biosynthesis. We propose that the alc mutant could be used as an animal model for drug evaluation for BH4 deficient PKU. PMID- 29596329 TI - Crystal Structure of CYP2B6 in Complex with an Efavirenz Analog. AB - The over two dozen CYP2B structures of human, rabbit, and woodrat enzymes solved in the last decade have significantly enhanced our understanding of the structure function relationships of drug metabolizing enzymes. More recently, an important role has emerged for halogen-pi interactions in the CYP2B6 active site in substrate selectivity, explaining in part the preference for halogenated ligands as substrates. The mechanism by which such ligands interact with CYP2B enzymes involves conserved phenylalanine side chains, in particular F108, F115, or F297, in the active site, which form pi bonds with halogens. To illustrate such halogen pi interactions using drugs that are major substrates of CYP2B6, we present here a crystal structure of CYP2B6 in complex with an analog of the widely used anti HIV drug efavirenz, which contains a methyl group in place of the carbonyl oxygen. The chlorine of the efavirenz analog forms a pi bond with the aromatic ring of F108, whereas the putative metabolism site on the distal end of the molecule is oriented towards the heme iron. The crystal structure showcases how CYP2B6 accommodates this important drug analog of considerable size in the active site by movement of various side chains without substantially increasing the active site volume. Furthermore, the CYP2B6-efavirenz analog complex provides a useful platform to investigate computationally as well as biophysically the effect of genetic polymorphisms on binding of the widely studied efavirenz. PMID- 29596330 TI - Modeling and Assessment of Precise Time Transfer by Using BeiDou Navigation Satellite System Triple-Frequency Signals. AB - This study proposes two models for precise time transfer using the BeiDou Navigation Satellite System triple-frequency signals: ionosphere-free (IF) combined precise point positioning (PPP) model with two dual-frequency combinations (IF-PPP1) and ionosphere-free combined PPP model with a single triple-frequency combination (IF-PPP2). A dataset with a short baseline (with a common external time frequency) and a long baseline are used for performance assessments. The results show that IF-PPP1 and IF-PPP2 models can both be used for precise time transfer using BeiDou Navigation Satellite System (BDS) triple frequency signals, and the accuracy and stability of time transfer is the same in both cases, except for a constant system bias caused by the hardware delay of different frequencies, which can be removed by the parameter estimation and prediction with long time datasets or by a priori calibration. PMID- 29596331 TI - Effect of Vertical Annealing on the Nitrogen Dioxide Response of Organic Thin Film Transistors. AB - Nitrogen dioxide (NO2) sensors based on organic thin-film transistors (OTFTs) were fabricated by conventional annealing (horizontal) and vertical annealing processes of organic semiconductor (OSC) films. The NO2 responsivity of OTFTs to 15 ppm of NO2 is 1408% under conditions of vertical annealing and only 72% when conventional annealing is applied. Moreover, gas sensors obtained by vertical annealing achieve a high sensing performance of 589% already at 1 ppm of NO2, while showing a preferential response to NO2 compared with SO2, NH3, CO, and H2S. To analyze the mechanism of performance improvement of OTFT gas sensors, the morphologies of 6,13-bis(triisopropylsilylethynyl)-pentacene (TIPS-pentacene) films were characterized by atomic force microscopy (AFM) in tapping mode. The results show that, in well-aligned TIPS-pentacene films, a large number of effective grain boundaries inside the conducting channel contribute to the enhancement of NO2 gas sensing performance. PMID- 29596332 TI - Semi-Automated Air-Coupled Impact-Echo Method for Large-Scale Parkade Structure. AB - Structural Health Monitoring (SHM) has moved to data-dense systems, utilizing numerous sensor types to monitor infrastructure, such as bridges and dams, more regularly. One of the issues faced in this endeavour is the scale of the inspected structures and the time it takes to carry out testing. Installing automated systems that can provide measurements in a timely manner is one way of overcoming these obstacles. This study proposes an Artificial Neural Network (ANN) application that determines intact and damaged locations from a small training sample of impact-echo data, using air-coupled microphones from a reinforced concrete beam in lab conditions and data collected from a field experiment in a parking garage. The impact-echo testing in the field is carried out in a semi-autonomous manner to expedite the front end of the in situ damage detection testing. The use of an ANN removes the need for a user-defined cutoff value for the classification of intact and damaged locations when a least-square distance approach is used. It is postulated that this may contribute significantly to testing time reduction when monitoring large-scale civil Reinforced Concrete (RC) structures. PMID- 29596333 TI - Patient as a Partner in Healthcare-Associated Infection Prevention. AB - OBJECTIVES: The objective of the study was getting to know the knowledge and attitudes towards hand hygiene (HH) among Polish patients and healthcare workers (HCWs). METHODS: 459 respondents replied to the survey: 173 (37.6%) patients and 286 (62.3%) HCWs; 57 HCWs were additionally interviewed. RESULTS: Few HCWs knew and used the "5 moments for HH" in the required situations. Both patients and HCWs rated HH of other HCWs poorly: only 75% of patients and 54% of HCWs noticed the application of HH before blood sample collection, but 1/2 of interviewed HCWs did not encounter a request for HH from a patient. According to interviews, 23 (40%) HCWs did not admonish others when they did not use HH. Seventy-five percent of patients and HCWs claimed that, in the past, in schools the toilets were poorly stocked, but the situation improved with the passage of time. CONCLUSIONS: There are barriers with resspect to treating patients as partners in HH in Polish hospitals and HCWs' lack of compliance with the "5 moments for HH" significantly reduces patients' safety. PRACTICE IMPLICATIONS: Education regarding HH should be conducted for the whole society from an early age: lack of proper supplies in school bathrooms impedes the development of positive HH habits. PMID- 29596335 TI - Poisson-Gaussian Noise Analysis and Estimation for Low-Dose X-ray Images in the NSCT Domain. AB - The noise distribution of images obtained by X-ray sensors in low-dosage situations can be analyzed using the Poisson and Gaussian mixture model. Multiscale conversion is one of the most popular noise reduction methods used in recent years. Estimation of the noise distribution of each subband in the multiscale domain is the most important factor in performing noise reduction, with non-subsampled contourlet transform (NSCT) representing an effective method for scale and direction decomposition. In this study, we use artificially generated noise to analyze and estimate the Poisson-Gaussian noise of low-dose X ray images in the NSCT domain. The noise distribution of the subband coefficients is analyzed using the noiseless low-band coefficients and the variance of the noisy subband coefficients. The noise-after-transform also follows a Poisson Gaussian distribution, and the relationship between the noise parameters of the subband and the full-band image is identified. We then analyze noise of actual images to validate the theoretical analysis. Comparison of the proposed noise estimation method with an existing noise reduction method confirms that the proposed method outperforms traditional methods. PMID- 29596336 TI - An Effective Hybrid Routing Algorithm in WSN: Ant Colony Optimization in combination with Hop Count Minimization. AB - Low cost, high reliability and easy maintenance are key criteria in the design of routing protocols for wireless sensor networks (WSNs). This paper investigates the existing ant colony optimization (ACO)-based WSN routing algorithms and the minimum hop count WSN routing algorithms by reviewing their strengths and weaknesses. We also consider the critical factors of WSNs, such as energy constraint of sensor nodes, network load balancing and dynamic network topology. Then we propose a hybrid routing algorithm that integrates ACO and a minimum hop count scheme. The proposed algorithm is able to find the optimal routing path with minimal total energy consumption and balanced energy consumption on each node. The algorithm has unique superiority in terms of searching for the optimal path, balancing the network load and the network topology maintenance. The WSN model and the proposed algorithm have been implemented using C++. Extensive simulation experimental results have shown that our algorithm outperforms several other WSN routing algorithms on such aspects that include the rate of convergence, the success rate in searching for global optimal solution, and the network lifetime. PMID- 29596334 TI - Tackling HIV Persistence: Pharmacological versus CRISPR-Based Shock Strategies. AB - Jan Svoboda studied aspects of viral latency, in particular with respect to disease induction by avian RNA tumor viruses, which were later renamed as part of the extended retrovirus family. The course of retroviral pathogenesis is intrinsically linked to their unique property of integrating the DNA copy of the retroviral genome into that of the host cell, thus forming the provirus. Retroviral latency has recently become of major clinical interest to allow a better understanding of why we can effectively block the human immunodeficiency virus type 1 (HIV-1) in infected individuals with antiviral drugs, yet never reach a cure. We will discuss HIV-1 latency and its direct consequence-the formation of long-lasting HIV-1 reservoirs. We next focus on one of the most explored strategies in tackling HIV-1 reservoirs-the "shock and kill" strategy which describes the broadly explored pharmacological way of kicking the latent provirus, with subsequent killing of the virus-producing cell by the immune system. We furthermore present how the clustered regularly interspaced palindromic repeats (CRISPR) and associated protein (Cas) system can be harnessed to reach the same objective by reactivating HIV-1 gene expression from latency. We will review the benefits and drawbacks of these different cure strategies. PMID- 29596337 TI - A Comparison of Inductive Sensors in the Characterization of Partial Discharges and Electrical Noise Using the Chromatic Technique. AB - Partial discharges (PDs) are one of the most important classes of ageing processes that occur within electrical insulation. PD detection is a standardized technique to qualify the state of the insulation in electric assets such as machines and power cables. Generally, the classical phase-resolved partial discharge (PRPD) patterns are used to perform the identification of the type of PD source when they are related to a specific degradation process and when the electrical noise level is low compared to the magnitudes of the PD signals. However, in practical applications such as measurements carried out in the field or in industrial environments, several PD sources and large noise signals are usually present simultaneously. In this study, three different inductive sensors have been used to evaluate and compare their performance in the detection and separation of multiple PD sources by applying the chromatic technique to each of the measured signals. PMID- 29596338 TI - Non-Invasive Electromagnetic Skin Patch Sensor to Measure Intracranial Fluid Volume Shifts. AB - Elevated intracranial fluid volume can drive intracranial pressure increases, which can potentially result in numerous neurological complications or death. This study's focus was to develop a passive skin patch sensor for the head that would non-invasively measure cranial fluid volume shifts. The sensor consists of a single baseline component configured into a rectangular planar spiral with a self-resonant frequency response when impinged upon by external radio frequency sweeps. Fluid volume changes (10 mL increments) were detected through cranial bone using the sensor on a dry human skull model. Preliminary human tests utilized two sensors to determine feasibility of detecting fluid volume shifts in the complex environment of the human body. The correlation between fluid volume changes and shifts in the first resonance frequency using the dry human skull was classified as a second order polynomial with R2 = 0.97. During preliminary and secondary human tests, a ~24 MHz and an average of ~45.07 MHz shifts in the principal resonant frequency were measured respectively, corresponding to the induced cephalad bio-fluid shifts. This electromagnetic resonant sensor may provide a non-invasive method to monitor shifts in fluid volume and assist with medical scenarios including stroke, cerebral hemorrhage, concussion, or monitoring intracranial pressure. PMID- 29596339 TI - Investigating Water Movement Within and Near Wells Using Active Point Heating and Fiber Optic Distributed Temperature Sensing. AB - There are few methods to provide high-resolution in-situ characterization of flow in aquifers and reservoirs. We present a method that has the potential to quantify lateral and vertical (magnitude and direction) components of flow with spatial resolution of about one meter and temporal resolution of about one day. A fiber optic distributed temperature sensor is used with a novel heating system. Temperatures before heating may be used to evaluate background geothermal gradient and vertical profile of thermal diffusivity. The innovation presented is the use of variable energy application along the well, in this case concentrated heating at equally-spaced (2 m) localized areas (0.5 m). Relative to uniform warming this offers greater opportunity to estimate water movement, reduces required heating power, and increases practical length that can be heated. Numerical simulations are presented which illustrate expected behaviors. We estimate relative advection rates near the well using the times at which various locations diverge from a heating trajectory expected for pure conduction in the absence of advection. The concept is demonstrated in a grouted 600 m borehole with 300 heated patches, though evidence of vertical water movement was not seen. PMID- 29596340 TI - Volterra Kernel Estimation of White Light LEDs in the Time Domain. AB - In this paper, we present a time domain method for extracting coefficients of nonlinear Volterra-series kernels for white light-emitting diodes (LED) used both for illumination and visible light communications. We show that this method may have several advantages over the thus far more popular frequency domain method. We successfully apply the measured kernel coefficients up to the 3rd order for the modeling of nonlinear distortion impact on advanced modulation formats: pulse amplitude modulation, carrierless amplitude phase and orthogonal frequency division multiplexing. The impact of blue filtering on dynamic nonlinearity is also presented. PMID- 29596341 TI - Tunable Nanosensor Based on Fano Resonances Created by Changing the Deviation Angle of the Metal Core in a Plasmonic Cavity. AB - In this paper, a type of tunable plasmonic refractive index nanosensor based on Fano resonance is proposed and investigated. The sensor comprises a metal insulator-metal (MIM) nanocavity with a center-deviated metal core and two side coupled waveguides. By carefully adjusting the deviation angle and distance of the metal core in the cavity, Fano resonances can be obtained and modulated. The Fano resonances can be considered as results induced by the symmetry-breaking or geometric effect that affects the field distribution intensity at the coupling region between the right waveguide and the cavity. Such a field-distribution pattern change can be regarded as being caused by the interference between the waveguide modes and the cavity modes. The investigations demonstrate that the spectral positions and modulation depths of Fano resonances are highly sensitive to the deviation parameters. Furthermore, the figure of merit (FOM) value is calculated for different deviation angle. The result shows that this kind of tunable sensor has compact structure, high transmission, sharp Fano lineshape, and high sensitivity to the change in background refractive index. This work provides an effective method for flexibly tuning Fano resonance, which has wide applications in designing on-chip plasmonic nanosensors or other relevant devices, such as information modulators, optical filters, and ultra-fast switches. PMID- 29596342 TI - Statistical Platform for Individualized Behavioral Analyses Using Biophysical Micro-Movement Spikes. AB - Wearable biosensors, such as those embedded in smart phones, can provide data to assess neuro-motor control in mobile settings, at homes, schools, workplaces and clinics. However, because most machine learning algorithms currently used to analyze such data require several steps that depend on human heuristics, the analyses become computationally expensive and rather subjective. Further, there is no standardized scale or set of tasks amenable to take advantage of such technology in ways that permit broad dissemination and reproducibility of results. Indeed, there is a critical need for fully objective automated analytical methods that easily handle the deluge of data these sensors output, while providing standardized scales amenable to apply across large sections of the population, to help promote personalized-mobile medicine. Here we use an open access data set from Kaggle.com to illustrate the use of a new statistical platform and standardized data types applied to smart phone accelerometer and gyroscope data from 30 participants, performing six different activities. We report full distinction without confusion of the activities from the Kaggle set using a single parameter (linear acceleration or angular speed). We further extend the use of our platform to characterize data from commercially available smart shoes, using gait patterns within a set of experiments that probe nervous systems functioning and levels of motor control. PMID- 29596344 TI - Treatment of Arsenite Intoxication-Induced Peripheral Vasculopathy with Mesenchymal Stem Cells. AB - Arsenite (As), a notorious toxic metal, is ubiquitously distributed in the earth and poses a serious threat to human health. Histopathological lesions of As intoxication are known as thromboangiitis obliterans, which are resistant to current treatment and often lead to lower limb amputation. In this study, we attempt to find that treatment with mesenchymal stem cells (MSCs) may be effective for As-induced vasculopathy. We first conducted an in vitro study with a co-culture system containing human MSCs and human umbilical vein endothelial cells (HUVECs) and treated individual and co-cultured cells with various concentrations of arsenite. We also designed an in vivo study in which Sprague Dawley (SD) rats received periodic intraperitoneal (IP) injections of 16 ppm arsenite for 12 weeks. MSCs were harvested from BALB/c mice that were transplanted via tail vein injection. We found that there was significantly higher cellular viability in human mesenchymal stem cells (hMSCs) than in HUVECs under concentrations of arsenite between 15 and 25 MUM. The Annexin V apoptosis assay further confirmed this finding. Cytokine array assay for As-conditioned media revealed an elevated vascular endothelial growth factor (VEGF) level secreted by MSCs, which is crucial for HUVEC survival and was evaluated by an siRNA VEGF knockdown test. In the in vivo study, we demonstrated early apoptotic changes in the anterior tibial vessels of As-injected SD rats with a Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, but these apoptotic changes were less frequently observed upon MSCs transplantation, indicating that the cytoprotective effect of MSCs successfully protected against As-induced peripheral vasculopathy. The feasibility of MSCs to treat and /or prevent the progression of As-induced vasculopathy is justified. Further clinical studies are required to demonstrate the therapeutic efficacy of MSCs in patients suffering from As intoxication with vasculopathy.

AB - This study aimed to estimate farmers' willingness to pay (WTP) for health risk reductions of pesticide use by applying the contingent valuation method (CVM) and to explore the factors that influence farmers' WTP in China. In total, 244 farmers were randomly selected and interviewed. The mean WTP was estimated to be $65.38 (0.94% of total household income) per household per year for a 5/10,000 reduction in morbidity risk. This study shows that farmers' socioeconomic and attitudinal factors that significantly affect their WTP include farmers' farming income, education, household size and risk perceptions. In particular, the results demonstrate that respondents' social trust, social reciprocity and social networks have significant impacts on their WTP. The findings of this study can provide useful insights for policy makers to design effective policies to address health problems related to pesticide use in the developing world. PMID- 29596343 TI - Antipruritic Effects of Botulinum Neurotoxins. AB - This review explores current evidence to demonstrate that botulinum neurotoxins (BoNTs) exert antipruritic effects. Both experimental and clinical conditions in which botulinum neurotoxins have been applied for pruritus relief will be presented and significant findings will be highlighted. Potential mechanisms underlying antipruritic effects will also be discussed and ongoing challenges and unmet needs will be addressed. PMID- 29596347 TI - Health Impacts and Economic Costs of Air Pollution in the Metropolitan Area of Skopje. AB - BACKGROUND: Urban outdoor air pollution, especially particulate matter, remains a major environmental health problem in Skopje, the capital of the former Yugoslav Republic of Macedonia. Despite the documented high levels of pollution in the city, the published evidence on its health impacts is as yet scarce. METHODS: we obtained, cleaned, and validated Particulate Matter (PM) concentration data from five air quality monitoring stations in the Skopje metropolitan area, applied relevant concentration-response functions, and evaluated health impacts against two theoretical policy scenarios. We then calculated the burden of disease attributable to PM and calculated the societal cost due to attributable mortality. RESULTS: In 2012, long-term exposure to PM2.5 (49.2 MUg/m3) caused an estimated 1199 premature deaths (CI95% 821-1519). The social cost of the predicted premature mortality in 2012 due to air pollution was estimated at between 570 and 1470 million euros. Moreover, PM2.5 was also estimated to be responsible for 547 hospital admissions (CI95% 104-977) from cardiovascular diseases, and 937 admissions (CI95% 937-1869) for respiratory disease that year. Reducing PM2.5 levels to the EU limit (25 MUg/m3) could have averted an estimated 45% of PM-attributable mortality, while achieving the WHO Air Quality Guidelines (10 MUg/m3) could have averted an estimated 77% of PM-attributable mortality. Both scenarios would also attain significant reductions in attributable respiratory and cardiovascular hospital admissions. CONCLUSIONS: Besides its health impacts in terms of increased premature mortality and hospitalizations, air pollution entails significant economic costs to the population of Skopje. Reductions in PM2.5 concentrations could provide substantial health and economic gains to the city. PMID- 29596346 TI - 1st German Phage Symposium-Conference Report. AB - In Germany, phage research and application can be traced back to the beginning of the 20th century. However, with the triumphal march of antibiotics around the world, the significance of bacteriophages faded in most countries, and respective research mainly focused on fundamental questions and niche applications. After a century, we pay tribute to the overuse of antibiotics that led to multidrug resistance and calls for new strategies to combat pathogenic microbes. Against this background, bacteriophages came into the spotlight of researchers and practitioners again resulting in a fast growing "phage community". In October 2017, part of this community met at the 1st German Phage Symposium to share their knowledge and experiences. The participants discussed open questions and challenges related to phage therapy and the application of phages in general. This report summarizes the presentations given, highlights the main points of the round table discussion and concludes with an outlook for the different aspects of phage application. PMID- 29596348 TI - New Gene Markers for Metabolic Processes and Homeostasis in Porcine Buccal Pouch Mucosa during Cells Long Term-Cultivation-A Primary Culture Approach. AB - The oral mucosal tissue is a compound structure composed of morphologically and physiologically different cell types. The morphological modification involves genetically determined lifespan, which may be recognized as the balance between cell survival and apoptosis. Although the biochemical processes and pathways in oral mucosa, with special regards to drug transport, delivery, and metabolism, are well known, the cellular physiological homeostasis in this tissue requires further investigation. The porcine buccal pouch mucosal cells (BPMCs) collected from 20 pubertal crossbred Landrace gilts, were used in this study. Immediately after recovery, the oral mucosa was separated micro-surgically, and treated enzymatically. The dispersed cells were transferred into primary in vitro culture systems for a long-term cultivation of 30 days. After each step of in vitro culture (IVC), the cells were collected for isolation of total RNA at 24 h, 7, 15, and 30 days of IVC. While the expression was analyzed for days 7, 15, and 30, the 24th hour was used as a reference for outcome calibration. The gene expression profile was determined using Affymetrix microarray assays and necessary procedures. In results, we observed significant up-regulation of SCARB1, PTGS2, DUSP5, ITGB3, PLK2, CCL2, TGFB1, CCL8, RFC4, LYN, ETS1, REL, LIF, SPP1, and FGER1G genes, belonging to two ontological groups, namely "positive regulation of metabolic process", and "regulation of homeostatic process" at 7 day of IVC as compared to down-regulation at days 15 and 30. These findings suggest that the metabolic processes and homeostatic regulations are much more intense in porcine mucosal cells at day 7 of IVC. Moreover, the increased expression of marker genes, for both of these ontological groups, may suggest the existence of not only "morphological lifespan" during tissue keratinization, but also "physiological checkpoint" dedicated to metabolic processes in oral mucosa. This knowledge may be useful for preclinical experiments with drugs delivery and metabolism in both animals and humans. PMID- 29596349 TI - Genome-Wide Analyses of the NAC Transcription Factor Gene Family in Pepper (Capsicum annuum L.): Chromosome Location, Phylogeny, Structure, Expression Patterns, Cis-Elements in the Promoter, and Interaction Network. AB - The NAM, ATAF1/2, and CUC2 (NAC) transcription factors form a large plant specific gene family, which is involved in the regulation of tissue development in response to biotic and abiotic stress. To date, there have been no comprehensive studies investigating chromosomal location, gene structure, gene phylogeny, conserved motifs, or gene expression of NAC in pepper (Capsicum annuum L.). The recent release of the complete genome sequence of pepper allowed us to perform a genome-wide investigation of Capsicum annuum L. NAC (CaNAC) proteins. In the present study, a comprehensive analysis of the CaNAC gene family in pepper was performed, and a total of 104 CaNAC genes were identified. Genome mapping analysis revealed that CaNAC genes were enriched on four chromosomes (chromosomes 1, 2, 3, and 6). In addition, phylogenetic analysis of the NAC domains from pepper, potato, Arabidopsis, and rice showed that CaNAC genes could be clustered into three groups (I, II, and III). Group III, which contained 24 CaNAC genes, was exclusive to the Solanaceae plant family. Gene structure and protein motif analyses showed that these genes were relatively conserved within each subgroup. The number of introns in CaNAC genes varied from 0 to 8, with 83 (78.9%) of CaNAC genes containing two or less introns. Promoter analysis confirmed that CaNAC genes are involved in pepper growth, development, and biotic or abiotic stress responses. Further, the expression of 22 selected CaNAC genes in response to seven different biotic and abiotic stresses [salt, heat shock, drought, Phytophthora capsici, abscisic acid, salicylic acid (SA), and methyl jasmonate (MeJA)] was evaluated by quantitative RT-PCR to determine their stress-related expression patterns. Several putative stress-responsive CaNAC genes, including CaNAC72 and CaNAC27, which are orthologs of the known stress-responsive Arabidopsis gene ANAC055 and potato gene StNAC30, respectively, were highly regulated by treatment with different types of stress. Our results also showed that CaNAC36 plays an important role in the interaction network, interacting with 48 genes. Most of these genes are in the mitogen-activated protein kinase (MAPK) family. Taken together, our results provide a platform for further studies to identify the biological functions of CaNAC genes. PMID- 29596351 TI - The DaNa2.0 Knowledge Base Nanomaterials-An Important Measure Accompanying Nanomaterials Development. AB - Nanotechnology is closely related to the tailored manufacturing of nanomaterials for a huge variety of applications. However, such applications with newly developed materials are also a reason for concern. The DaNa2.0 project provides information and support for these issues on the web in condensed and easy-to understand wording. Thus, a key challenge in the field of advanced materials safety research is access to correct and reliable studies and validated results. For nanomaterials, there is currently a continuously increasing amount of publications on toxicological issues, but criteria to evaluate the quality of these studies are necessary to use them e.g., for regulatory purposes. DaNa2.0 discusses scientific results regarding 26 nanomaterials based on actual literature that has been selected after careful evaluation following a literature criteria checklist. This checklist is publicly available, along with a selection of standardized operating protocols (SOPs) established by different projects. The spectrum of information is rounded off by further articles concerning basics or crosscutting topics in nanosafety research. This article is intended to give an overview on DaNa2.0 activities to support reliable toxicity testing and science communication alike. PMID- 29596350 TI - Recurrent Renal Colic in a Patient with Munchausen Syndrome. AB - BACKGROUND: In most of the cases regarding children, factitious disorders (FDs) are intentionally produced by parents. Less attention is paid to FDs in which a child or adolescent intentionally induces or falsifies the disease to attain a patient's role. CASE PRESENTATION: A 13-year-old immigrated and adopted boy previously underwent an operation for renal joint syndrome and was affected by recurrent episodes of renal colic. The boy was admitted reporting acute left flank pain with scars on the mucous face of his prepuce and had a recent previous hospitalization for the same reason. Laboratory tests and radiological findings did not reveal any morphological or functional alterations. Self-induced FD was suspected, and a psychiatric consultation was performed. After psychiatric consultation and remission of the symptoms with a placebo, a diagnosis of Munchausen syndrome was suspected. The patient's uncle was not initially convinced of the diagnosis. Some videos clearly showed that the boy was handling his prepuce to excrete stones, explaining the scars. A therapeutic plan with psychiatrist support was later accepted with a positive outcome. No further signs and symptoms of renal colic were reported. CONCLUSIONS: It is recommended that paediatricians include FD in the differential diagnosis of a persistent and unexplained medical condition. If suspicion arises, confirmation and long-term therapy by a group of qualified specialists, including psychiatrists, should be planned. PMID- 29596353 TI - Benveniste's Experiments Explained by a Non-Conventional Experimenter Effect. AB - Background: Benveniste's biology experiments suggested the existence of molecular like effects without molecules ("memory of water"). In this article, it is proposed that these disputed experiments could have been the consequence of a previously unnoticed and non-conventional experimenter effect. Methods: A probabilistic modelling is built in order to describe an elementary laboratory experiment. A biological system is modelled with two possible states ("resting" and "activated") and exposed to two experimental conditions labelled "control" and "test", but both are biologically inactive. The modelling takes into account not only the biological system, but also the experimenters. In addition, an outsider standpoint is adopted to describe the experimental situation. Results: A classical approach suggests that, after experiment completion, the "control" and "test" labels of biologically-inactive conditions should both be associated with the "resting" state (i.e., no significant relationship between labels and system states). However, if the fluctuations of the biological system are also considered, a quantum-like relationship emerges and connects labels and system states (analogous to a biological "effect" without molecules). Conclusions: No hypotheses about water properties or other exotic explanations are needed to describe Benveniste's experiments, including their unusual features. This modelling could be extended to other experimental situations in biology, medicine, and psychology. PMID- 29596352 TI - Electrospun Composites of Polycaprolactone and Porous Silicon Nanoparticles for the Tunable Delivery of Small Therapeutic Molecules. AB - This report describes the use of an electrospun composite of poly(epsilon caprolactone) (PCL) fibers and porous silicon (pSi) nanoparticles (NPs) as an effective system for the tunable delivery of camptothecin (CPT), a small therapeutic molecule. Both materials are biodegradable, abundant, low-cost, and most importantly, have no known cytotoxic effects. The composites were treated with and without sodium hydroxide (NaOH) to investigate the wettability of the porous network for drug release and cell viability measurements. CPT release and subsequent cell viability was also investigated. We observed that the cell death rate was not only affected by the addition of our CPT carrier, pSi, but also by increasing the rate of dissolution via treatment with NaOH. This is the first example of loading pSi NPs as a therapeutics nanocarrier into electronspun PCL fibers and this system opens up new possibilities for the delivery of molecular therapeutics. PMID- 29596354 TI - A New Breviane Spiroditerpenoid from the Marine-Derived Fungus Penicillium sp. TJ403-1. AB - Marine-derived fungi are a promising and untapped reservoir for discovering structurally interesting and pharmacologically active natural products. In our efforts to identify novel bioactive compounds from marine-derived fungi, four breviane spiroditerpenoids, including a new compound, brevione O (1), and three known compounds breviones I (2), J (3), and H (4), together with a known diketopiperazine alkaloid brevicompanine G (5), were isolated and identified from an ethyl acetate extract of the fermented rice substrate of the coral-derived fungus Penicillium sp. TJ403-1. The absolute structure of 1 was elucidated by HRESIMS, one- and two-dimensional NMR spectroscopic data, and a comparison of its electronic circular dichroism (ECD) spectrum with the literature. Moreover, we confirmed the absolute configuration of 5 by single-crystal X-ray crystallography. All the isolated compounds were evaluated for isocitrate dehydrogenase 1 (IDH1) inhibitory activity and cytotoxicity, and compound 2 showed significant inhibitory activities against HL-60, A-549, and HEP3B tumor cell lines with IC50 values of 4.92 +/- 0.65, 8.60 +/- 1.36, and 5.50 +/- 0.67 uM, respectively. PMID- 29596355 TI - Occurrence of Functional Molecules in the Flowers of Tea (Camellia sinensis) Plants: Evidence for a Second Resource. AB - Tea (Camellia sinensis) is an important crop, and its leaves are used to make the most widely consumed beverage, aside from water. People have been using leaves from tea plants to make teas for a long time. However, less attention has been paid to the flowers of tea plants, which is a waste of an abundant resource. In the past 15 years, researchers have attempted to discover, identify, and evaluate functional molecules from tea flowers, and have made insightful and useful discoveries. Here, we summarize the recent investigations into these functional molecules in tea flowers, including functional molecules similar to those in tea leaves, as well as the preponderant functional molecules in tea flowers. Tea flowers contain representative metabolites similar to those of tea leaves, such as catechins, flavonols, caffeine, and amino acids. The preponderant functional molecules in tea flowers include saponins, polysaccharides, aromatic compounds, spermidine derivatives, and functional proteins. We also review the safety and biological functions of tea flowers. Tea flower extracts are proposed to be of no toxicological concern based on evidence from the evaluation of mutagenicity, and acute and subchronic toxicity in rats. The presence of many functional metabolites in tea flowers indicates that tea flowers possess diverse biological functions, which are mostly related to catechins, polysaccharides, and saponins. Finally, we discuss the potential for, and challenges facing, future applications of tea flowers as a second resource from tea plants. PMID- 29596356 TI - Dissipation and Migration of Pyrethroids in Auricularia polytricha Mont. from Cultivation to Postharvest Processing and Dietary Risk. AB - In order to ensure raw consumption safety the dissipation behavior, migration, postharvest processing, and dietary risk assessment of five pyrethroids in mushroom (Auricularia polytricha Mont.) cultivated under Chinese greenhouse-field conditions. Half-lives (t1/2) of pyrethroids in fruiting body and substrate samples were 3.10-5.26 and 17.46-40.06 d, respectively. Fenpropathrin dissipated rapidly in fruiting bodies (t1/2 3.10 d); bifenthrin had the longest t1/2. At harvest, pyrethroid residues in A. polytricha (except fenpropathrin) were above the respective maximum residue limits (MRLs). Some migration of lambda cyhalothrin was observed in the substrate-fruit body system. In postharvest processing, sun-drying and soaking reduced pyrethroid residues by 25-83%. We therefore recommend that consumers soak these mushrooms in 0.5% NaHCO3 at 50 degrees C for 90 min. Pyrethroids exhibit a particularly low PF value of 0.08 0.13%, resulting in a negligible exposure risk upon mushroom consumption. This study provides guidance for the safe application of pyrethroids to edible fungi, and for the establishment of MRLs in mushrooms to reduce pesticide exposure in humans. PMID- 29596357 TI - The Influence of Metakaolinite on the Development of Thermal Cracks in a Cement Matrix. AB - In the paper the cluster cracks of cement paste that has been modified with metakaolinite was analyzed. The samples were loaded with an elevated temperature based on a thermal shock. To describe the crack structure, three stereological parameters were proposed to measure: (i) the cluster average area ( A - ); (ii) the cluster average perimeter ( L - ); and (iii) the crack average width ( I - ). The computer image analysis was implemented in the study, and 4 series of samples were subjected to the examination. In two series, metakaolinite was used as a substitute for 10% of a cement's mass. An assessment of the basic physico mechanical characteristics of the cement matrix was also carried out. The structure of the cement paste was considered as a highly concentrated dispersion system, in which the interactions between the cement's grains at the initial stage of the structure self-assembly affect the crack characteristics. The study has been supplemented with microstructural investigations using a scanning electron microscope and an X-ray microanalyzer. The conducted research indicated the direction of changes in the geometrical characteristics of thermal cracks if the technological variables of the material are subjected to modification. It was also confirmed that the cluster structures have fractal character and can be analyzed and observed on many levels of a structural heterogeneity. PMID- 29596358 TI - Porous Polyethylene Coated with Functionalized Hydroxyapatite Particles as a Bone Reconstruction Material. AB - In this study, porous polyethylene scaffolds were examined as bone substitutes in vitro and in vivo in critical-sized calvarial bone defects in transgenic Sprague Dawley rats. A microscopic examination revealed that the pores appeared to be interconnected across the material, making them suitable for cell growth. The creep recovery behavior of porous polyethylene at different loads indicated that the creep strain had two main portions. In both portions, strain increased with increased applied load and temperature. In terms of the thermographic behavior of the material, remarkable changes in melting temperature and heat fusion were revealed with increased the heating rates. The tensile strength results showed that the material was sensitive to the strain rate and that there was adequate mechanical strength to support cell growth. The in vitro cell culture results showed that human bone marrow mesenchymal stem cells attached to the porous polyethylene scaffold. Calcium sulfate-hydroxyapatite (CS-HA) coating of the scaffold not only improved attachment but also increased the proliferation of human bone marrow mesenchymal stem cells. In vivo, histological analysis showed that the study groups had active bone remodeling at the border of the defect. Bone regeneration at the border was also evident, which confirmed that the polyethylene acted as an osteoconductive bone graft. Furthermore, bone formation inside the pores of the coated polyethylene was also noted, which would enhance the process of osteointegration. PMID- 29596359 TI - Advances in Materials for Recent Low-Profile Implantable Bioelectronics. AB - The rapid development of micro/nanofabrication technologies to engineer a variety of materials has enabled new types of bioelectronics for health monitoring and disease diagnostics. In this review, we summarize widely used electronic materials in recent low-profile implantable systems, including traditional metals and semiconductors, soft polymers, biodegradable metals, and organic materials. Silicon-based compounds have represented the traditional materials in medical devices, due to the fully established fabrication processes. Examples include miniaturized sensors for monitoring intraocular pressure and blood pressure, which are designed in an ultra-thin diaphragm to react with the applied pressure. These sensors are integrated into rigid circuits and multiple modules; this brings challenges regarding the fundamental material's property mismatch with the targeted human tissues, which are intrinsically soft. Therefore, many polymeric materials have been investigated for hybrid integration with well-characterized functional materials such as silicon membranes and metal interconnects, which enable soft implantable bioelectronics. The most recent trend in implantable systems uses transient materials that naturally dissolve in body fluid after a programmed lifetime. Such biodegradable metallic materials are advantageous in the design of electronics due to their proven electrical properties. Collectively, this review delivers the development history of materials in implantable devices, while introducing new bioelectronics based on bioresorbable materials with multiple functionalities. PMID- 29596360 TI - A Reversible Bis(Salamo)-Based Fluorescence Sensor for Selective Detection of Cd2+ in Water-Containing Systems and Food Samples. AB - A novel, simple, highly selective, and sensitive fluorescence chemosensor for detecting Cd2+ that was constructed from a bis(salamo)-type compound (H4L) with two N2O2 chelating moieties as ionophore was successfully developed. Sensor H4L could show fluorescence turn-on response rapidly and significant selectivity to Cd2+ over many other metallic ions (Cu2+, Ba2+, Ca2+, K+, Cr3+, Mn2+, Sr2+, Co2+, Na+, Li+, Ni2+, Ag+, and Zn2+), and a clear change in color from colorless to yellow that can be very easily observed via the naked eyes in the existence of Cd2+, while other metallic ions do not induce such a change. Interestingly, its fluorescent intensity was increased sharply with the increased concentration of Cd2+. The detection limit of sensor H4L towards Cd2+ was down to 8.61 * 10-7 M. PMID- 29596361 TI - Optimal Serum Ferritin Levels for Iron Deficiency Anemia during Oral Iron Therapy (OIT) in Japanese Hemodialysis Patients with Minor Inflammation and Benefit of Intravenous Iron Therapy for OIT-Nonresponders. AB - Background: We determined optimal serum ferritin for oral iron therapy (OIT) in hemodialysis (HD) patients with iron deficiency anemia (IDA)/minor inflammation, and benefit of intravenous iron therapy (IIT) for OIT-nonresponders. Methods: Inclusion criteria were IDA (Hb <120 g/L, serum ferritin <227.4 pmol/L). Exclusion criteria were inflammation (C-reactive protein (CRP) >= 5 mg/L), bleeding, or cancer. IIT was withheld >3 months before the study. DeltaHb >= 20 g/L above baseline or maintaining target Hb (tHB; 120-130 g/L) was considered responsive. Fifty-one patients received OIT (ferrous fumarate, 50 mg/day) for 3 months; this continued in OIT-responders but was switched to IIT (saccharated ferric oxide, 40 mg/week) in OIT-nonresponders for 4 months. All received continuous erythropoietin receptor activator (CERA). Hb, ferritin, hepcidin-25, and CERA dose were measured. Results: Demographics before OIT were similar between OIT-responders and OIT-nonresponders except low Hb and high triglycerides in OIT-nonresponders. Thirty-nine were OIT-responders with reduced CERA dose. Hb rose with a peak at 5 months. Ferritin and hepcidin-25 continuously increased. Hb positively correlated with ferritin in OIT-responders (r = 0.913, p = 0.03) till 5 months after OIT. The correlation equation estimated optimal ferritin of 30-40 ng/mL using tHb (120-130 g/L). Seven OIT-nonresponders were IIT-responders. Conclusions: Optimal serum ferritin for OIT is 67.4-89.9 pmol/L in HD patients with IDA/minor inflammation. IIT may be a second line of treatment for OIT nonreponders. PMID- 29596362 TI - Both Mother and Infant Require a Vitamin D Supplement to Ensure That Infants' Vitamin D Status Meets Current Guidelines. AB - We examined the association between maternal vitamin D intake during breastfeeding with their infants' vitamin D status in infants who did or did not receive vitamin D supplements to determine whether infant supplementation was sufficient. Using plasma from a subset of breastfed infants in the APrON (Alberta Pregnant Outcomes and Nutrition) cohort, vitamin D status was measured by liquid chromatography-tandem mass spectrometry. Maternal and infants' dietary data were obtained from APrON's dietary questionnaires. The median maternal vitamin D intake was 665 International Units (IU)/day, while 25% reported intakes below the recommended 400 IU/day. Of the 224 infants in the cohort, 72% were exclusively breastfed, and 90% were receiving vitamin D supplements. Infants' median 25(OH)D was 96.0 nmol/L (interquartile ranges (IQR) 77.6-116.2), and 25% had 25(OH)D < 75 nmol/L. An adjusted linear regression model showed that, with a 100 IU increase in maternal vitamin D intake, infants' 25(OH)D increased by 0.9 nmol/L controlling for race, season, mid-pregnancy maternal 25(OH)D, birthweight, and whether the infant received daily vitamin D supplement (beta = 0.008, 95% confidence interval (CI) 0.002, 0.13). These results suggest that, to ensure infant optimal vitamin D status, not only do infants require a supplement, but women also need to meet current recommended vitamin D intake during breastfeeding. PMID- 29596363 TI - PCLPred: A Bioinformatics Method for Predicting Protein-Protein Interactions by Combining Relevance Vector Machine Model with Low-Rank Matrix Approximation. AB - Protein-protein interactions (PPI) are key to protein functions and regulations within the cell cycle, DNA replication, and cellular signaling. Therefore, detecting whether a pair of proteins interact is of great importance for the study of molecular biology. As researchers have become aware of the importance of computational methods in predicting PPIs, many techniques have been developed for performing this task computationally. However, there are few technologies that really meet the needs of their users. In this paper, we develop a novel and efficient sequence-based method for predicting PPIs. The evolutionary features are extracted from the position-specific scoring matrix (PSSM) of protein. The features are then fed into a robust relevance vector machine (RVM) classifier to distinguish between the interacting and non-interacting protein pairs. In order to verify the performance of our method, five-fold cross-validation tests are performed on the Saccharomyces cerevisiae dataset. A high accuracy of 94.56%, with 94.79% sensitivity at 94.36% precision, was obtained. The experimental results illustrated that the proposed approach can extract the most significant features from each protein sequence and can be a bright and meaningful tool for the research of proteomics. PMID- 29596365 TI - UBE2C Is a Transcriptional Target of the Cell Cycle Regulator FOXM1. AB - FOXM1 (forkhead box protein M1) is a transcription factor that participates in all stages of tumor development, mainly through the control of cell cycle and proliferation, regulating the expression of genes involved in G1/S and G2/M transition and M phase progression. The ubiquitin conjugating enzyme E2 (UBE2C) is a member of the anaphase promoting complex/cyclosome, promoting the degradation of several target proteins along cell cycle progression, during metaphase/anaphase transition. FOXM1 and UBE2C have been found overexpressed in a wide range of different solid tumors. Therefore, the aim of this study was to investigate whether UBE2C is a transcriptional target of FOXM1, using esophageal squamous cell carcinoma (ESCC) as a model, in addition to several cancer deposited data. Our results show that FOXM1 and UBE2C expression present a positive correlation in normal tissues and in 25 distinct tumor types, including ESCC, where these genes are overexpressed. Moreover, FOXM1 binds to UBE2C promoter region in ESCC cell line and transcriptionally activates it, leading to UBE2C upregulation. In conclusion, this study provides evidences that FOXM1 transcriptionally regulates UBE2C expression in ESCC and their deregulation may be a general phenomenon in human neoplasias. PMID- 29596364 TI - Non-Coding RNAs and Endometrial Cancer. AB - Non-coding RNAs (ncRNAs) are involved in the regulation of cell metabolism and neoplastic transformation. Recent studies have tried to clarify the significance of these information carriers in the genesis and progression of various cancers and their use as biomarkers for the disease; possible targets for the inhibition of growth and invasion by the neoplastic cells have been suggested. The significance of ncRNAs in lung cancer, bladder cancer, kidney cancer, and melanoma has been amply investigated with important results. Recently, the role of long non-coding RNAs (lncRNAs) has also been included in cancer studies. Studies on the relation between endometrial cancer (EC) and ncRNAs, such as small ncRNAs or micro RNAs (miRNAs), transfer RNAs (tRNAs), ribosomal RNAs (rRNAs), antisense RNAs (asRNAs), small nuclear RNAs (snRNAs), Piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs), competing endogenous RNAs (ceRNAs), lncRNAs, and long intergenic ncRNAs (lincRNAs) have been published. The recent literature produced in the last three years was extracted from PubMed by two independent readers, which was then selected for the possible relation between ncRNAs, oncogenesis in general, and EC in particular. PMID- 29596366 TI - Temporal and Spatial Variation in, and Population Exposure to, Summertime Ground Level Ozone in Beijing. AB - Ground-level ozone pollution in Beijing has been causing concern among the public due to the risks posed to human health. This study analyzed the temporal and spatial distribution of, and investigated population exposure to, ground-level ozone. We analyzed hourly ground-level ozone data from 35 ambient air quality monitoring sites, including urban, suburban, background, and traffic monitoring sites, during the summer in Beijing from 2014 to 2017. The results showed that the four-year mean ozone concentrations for urban, suburban, background, and traffic monitoring sites were 95.1, 99.8, 95.9, and 74.2 MUg/m3, respectively. A total of 44, 43, 45, and 43 days exceeded the Chinese National Ambient Air Quality Standards (NAAQS) threshold for ground-level ozone in 2014, 2015, 2016, and 2017, respectively. The mean ozone concentration was higher in suburban sites than in urban sites, and the traffic monitoring sites had the lowest concentration. The diurnal variation in ground-level ozone concentration at the four types of monitoring sites displayed a single-peak curve. The peak and valley values occurred at 3:00-4:00 p.m. and 7:00 a.m., respectively. Spatially, ground level ozone concentrations decreased in gradient from the north to the south. Population exposure levels were calculated based on ground-level ozone concentrations and population data. Approximately 50.38%, 44.85%, and 48.49% of the total population of Beijing were exposed to ground-level ozone concentrations exceeding the Chinese NAAQS threshold in 2014, 2015, and 2016, respectively. PMID- 29596367 TI - Carbene Transfer Reactions Catalysed by Dyes of the Metalloporphyrin Group. AB - Carbene transfer reactions are very important transformations in organic synthesis, allowing the generation of structurally challenging products by catalysed cyclopropanation, cyclopropenation, carbene C-H, N-H, O-H, S-H, and Si H insertion, and olefination of carbonyl compounds. In particular, chiral and achiral metalloporphyrins have been successfully explored as biomimetic catalysts for these carbene transfer reactions under both homogeneous and heterogeneous conditions. In this work the use of synthetic metalloporphyrins (MPorph, M = Fe, Ru, Os, Co, Rh, Ir, Sn) as homogeneous or heterogeneous catalysts for carbene transfer reactions in the last years is reviewed, almost exclusively focused on the literature since the year 2010, except when reference to older publications was deemed to be crucial. PMID- 29596368 TI - UHPLC-MS Metabolome Fingerprinting: The Isolation of Main Compounds and Antioxidant Activity of the Andean Species Tetraglochin ameghinoi (Speg.) Speg. AB - The seriated extracts of petroleum ether (PE-E), dichloromethane (DCM-E) and methanol extracts (MeOH-E) from the aerial parts of the native South American plant Tetraglochin ameghinoi (Rosaceae), were evaluated regarding their antioxidant and antibacterial activities. The antioxidant properties were evaluated by free radical scavenging methods (DPPH and TEAC), ferric-reducing antioxidant power (FRAP) and lipoperoxidation in erythrocytes (LP), while the antibacterial activity was performed against Gram-positive and Gram-negative bacteria according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. The chemical and biological analyses of this plant are very important since this bush is currently used in traditional medicine as a cholagogue and digestive. The polar MeOH-E showed the highest antioxidant activities (17.70 ug/mL in the DPPH assay, 381.43 +/- 22.38 mM TE/g extract in the FRAP assay, 387.76 +/- 91.93 mg TE/g extract in the TEAC assay and 93.23 + 6.77% in the LP assay) and it was selected for chromatographic isolation of its components. These components were found to be four acetophenones, including the new phloracetophenone glucoside: 4',6',-dihydroxy-2'-O-(6"-acetyl)-beta-d glucopyranosylacetophenone or IUPAC name: (6-(2-acetyl-3,5-dihydroxyphenoxy) 3,4,5-trihydroxytetrahydro-2H-pyran-2-yl)methyl acetate, whose structure was elucidated by NMR and MS methods. In addition, twenty-six compounds, including five of these acetophenone derivatives, two sugars, six flavonoids, eleven phenolic acids and two triterpenes, were identified based on UHPLC-OT-MS and PDA analysis on the MeOH-E. The results support the medicinal use of the plant. PMID- 29596369 TI - New Statistical Approach to Apportion Dietary Sources of Iodine Intake: Findings from Kenya, Senegal and India. AB - Progress of national Universal Salt Iodization (USI) strategies is typically assessed by household coverage of adequately iodized salt and median urinary iodine concentration (UIC) in spot urine collections. However, household coverage does not inform on the iodized salt used in preparation of processed foods outside homes, nor does the total UIC reflect the portion of population iodine intake attributable to the USI strategy. This study used data from three population-representative surveys of women of reproductive age (WRA) in Kenya, Senegal and India to develop and illustrate a new approach to apportion the population UIC levels by the principal dietary sources of iodine intake, namely native iodine, iodine in processed food salt and iodine in household salt. The technique requires measurement of urinary sodium concentrations (UNaC) in the same spot urine samples collected for iodine status assessment. Taking into account the different complex survey designs of each survey, generalized linear regression (GLR) analyses were performed in which the UIC data of WRA was set as the outcome variable that depends on their UNaC and household salt iodine (SI) data as explanatory variables. Estimates of the UIC portions that correspond to iodine intake sources were calculated with use of the intercept and regression coefficients for the UNaC and SI variables in each country's regression equation. GLR coefficients for UNaC and SI were significant in all country-specific models. Rural location did not show a significant association in any country when controlled for other explanatory variables. The estimated UIC portion from native dietary iodine intake in each country fell below the minimum threshold for iodine sufficiency. The UIC portion arising from processed food salt in Kenya was substantially higher than in Senegal and India, while the UIC portions from household salt use varied in accordance with the mean level of household SI content in the country surveys. The UIC portions and all-salt-derived iodine intakes found in this study were illustrative of existing differences in national USI legislative frameworks and national salt supply situations between countries. The approach of apportioning the population UIC from spot urine collections may be useful for future monitoring of change in iodine nutrition from reduced salt use in processed foods and in households. PMID- 29596371 TI - Experimental Characterization of Stress- and Strain-Dependent Stiffness in Grouted Rock Masses. AB - Grouting of fractured rock mass prior to excavation results in grout-filled discontinuities that govern the deformation characteristics of a site. The influence of joint characteristics on the properties of grouted rocks is important in assessing the effects of grouting on jointed rock mass. However, grouting remains a predominantly empirical practice and the effects of grouting on rock joint behavior and material properties have yet to be accurately assessed. Granular materials, including jointed rocks, typically display nonlinear strain-dependent responses that can be characterized by the shear modulus degradation curve. In this study, the effects of grouting on the strain dependent shear stiffness of jointed rock mass were investigated at the small strain (below 10-5) and mid-strain (10-5 to 10-3) ranges using the quasi-static resonant column test and rock mass dynamic test devices. The effects of curing time, axial stress, initial joint roughness, and grouted joint thickness were examined. The results show that (1) grouting of rock joints leads to decreased stress sensitivity and increased small-strain shear stiffness for all tested samples; (2) the grouted rock samples display similar modulus degradation characteristics as the applied grout material; (3) the initial joint roughness determines the stress-dependent behaviors and general stiffness range of the jointed and grouted rocks, but the strain-dependent behaviors are dependent on the properties of the grout material; (4) increased grouted joint thickness results in larger contribution of the grout properties in the overall grouted rock mass. PMID- 29596370 TI - Production, Characterization and Biocompatibility Evaluation of Collagen Membranes Derived from Marine Sponge Chondrosia reniformis Nardo, 1847. AB - Collagen is involved in the formation of complex fibrillar networks, providing the structural integrity of tissues. Its low immunogenicity and mechanical properties make this molecule a biomaterial that is extremely suitable for tissue engineering and regenerative medicine (TERM) strategies in human health issues. Here, for the first time, we performed a thorough screening of four different methods to obtain sponge collagenous fibrillar suspensions (FSs) from C. reniformis demosponge, which were then chemically, physically, and biologically characterized, in terms of protein, collagen, and glycosaminoglycans content, viscous properties, biocompatibility, and antioxidant activity. These four FSs were then tested for their capability to generate crosslinked or not thin sponge collagenous membranes (SCMs) that are suitable for TERM purposes. Two types of FSs, of the four tested, were able to generate SCMs, either from crosslinking or not, and showed good mechanical properties, enzymatic degradation resistance, water binding capacity, antioxidant activity, and biocompatibility on both fibroblast and keratinocyte cell cultures. Finally, our results demonstrate that it is possible to adapt the extraction procedure in order to alternatively improve the mechanical properties or the antioxidant performances of the derived biomaterial, depending on the application requirements, thanks to the versatility of C. reniformis extracellular matrix extracts. PMID- 29596372 TI - Fabrication and Characterization of Aligned Flexible Lead-Free Piezoelectric Nanofibers for Wearable Device Applications. AB - Flexible lead-free piezoelectric nanofibers, based on BNT-ST (0.78Bi0.5Na0.5TiO3 0.22SrTiO3) ceramic and poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) copolymers, were fabricated by an electrospinning method and the effects of the degree of alignment in the nanofibers on the piezoelectric characteristics were investigated. The microstructure of the lead-free piezoelectric nanofibers was observed by field emission scanning electron microscope (FE-SEM) and the orientation was analyzed by fast Fourier transform (FFT) images. X-ray diffraction (XRD) analysis confirmed that the phase was not changed by the electrospinning process and maintained a perovskite phase. Polarization-electric field (P-E) loops and piezoresponse force microscopy (PFM) were used to investigate the piezoelectric properties of the piezoelectric nanofibers, according to the degree of alignment-the well aligned piezoelectric nanofibers had higher piezoelectric properties. Furthermore, the output voltage of the aligned lead-free piezoelectric nanofibers was measured according to the vibration frequency and the bending motion and the aligned piezoelectric nanofibers with a collector rotation speed of 1500 rpm performed the best. PMID- 29596373 TI - Few-Layer MoS2 Nanodomains Decorating TiO2 Nanoparticles: A Case Study for the Photodegradation of Carbamazepine. AB - S-doped TiO2 and hybrid MoS2/TiO2 systems have been synthesized, via the sulfidation with H2S of the bare TiO2 and of MoOx supported on TiO2 systems, with the aim of enhancing the photocatalytic properties of TiO2 for the degradation of carbamazepine, an anticonvulsant drug, whose residues and metabolites are usually inefficiently removed in wastewater treatment plants. The focus of this study is to find a relationship between the morphology/structure/surface properties and photoactivity. The full characterization of samples reveals the strong effects of the H2S action on the properties of TiO2, with the formation of defects at the surface, as shown by transmission electron microscopy (TEM) and infrared spectroscopy (IR), while also the optical properties are strongly affected by the sulfidation treatment, with changes in the electronic states of TiO2. Meanwhile, the formation of small and thin few-layer MoS2 domains, decorating the TiO2 surface, is evidenced by both high-resolution transmission electron microscopy (HRTEM) and UV-Vis/Raman spectroscopies, while Fourier-transform infrared (FTIR) spectra give insights into the nature of Ti and Mo surface sites. The most interesting findings of our research are the enhanced photoactivity of the MoS2/TiO2 hybrid photocatalyst toward the carbamazepine mineralization. Surprisingly, the formation of hazardous compounds (i.e., acridine derivatives), usually obtained from carbamazepine, is precluded when treated with MoS2/TiO2 systems. PMID- 29596374 TI - Dissecting the Mutational Landscape of Cutaneous Melanoma: An Omic Analysis Based on Patients from Greece. AB - Melanoma is a lethal type of skin cancer, unless it is diagnosed early. Formalin fixed, paraffin-embedded (FFPE) tissue is a valuable source for molecular assays after diagnostic examination, but isolated nucleic acids often suffer from degradation. Here, for the first time, we examine primary melanomas from Greek patients, using whole exome sequencing, so as to derive their mutational profile. Application of a bioinformatic framework revealed a total of 10,030 somatic mutations. Regarding the genes containing putative protein-altering mutations, 73 were common in at least three patients. Sixty-five of these 73 top common genes have been previously identified in melanoma cases. Biological processes related to melanoma were affected by varied genes in each patient, suggesting differences in the components of a pathway possibly contributing to pathogenesis. We performed a multi-level analysis highlighting a short list of candidate genes with a probable causative role in melanoma. PMID- 29596375 TI - Comparative Performance Analysis of Support Vector Machine, Random Forest, Logistic Regression and k-Nearest Neighbours in Rainbow Trout (Oncorhynchus Mykiss) Classification Using Image-Based Features. AB - The main aim of this study was to develop a new objective method for evaluating the impacts of different diets on the live fish skin using image-based features. In total, one-hundred and sixty rainbow trout (Oncorhynchus mykiss) were fed either a fish-meal based diet (80 fish) or a 100% plant-based diet (80 fish) and photographed using consumer-grade digital camera. Twenty-three colour features and four texture features were extracted. Four different classification methods were used to evaluate fish diets including Random forest (RF), Support vector machine (SVM), Logistic regression (LR) and k-Nearest neighbours (k-NN). The SVM with radial based kernel provided the best classifier with correct classification rate (CCR) of 82% and Kappa coefficient of 0.65. Although the both LR and RF methods were less accurate than SVM, they achieved good classification with CCR 75% and 70% respectively. The k-NN was the least accurate (40%) classification model. Overall, it can be concluded that consumer-grade digital cameras could be employed as the fast, accurate and non-invasive sensor for classifying rainbow trout based on their diets. Furthermore, these was a close association between image-based features and fish diet received during cultivation. These procedures can be used as non-invasive, accurate and precise approaches for monitoring fish status during the cultivation by evaluating diet's effects on fish skin. PMID- 29596376 TI - Quantifying the Accuracy of Digital Hemispherical Photography for Leaf Area Index Estimates on Broad-Leaved Tree Species. AB - Digital hemispherical photography (DHP) has been widely used to estimate leaf area index (LAI) in forestry. Despite the advancement in the processing of hemispherical images with dedicated tools, several steps are still manual and thus easily affected by user's experience and sensibility. The purpose of this study was to quantify the impact of user's subjectivity on DHP LAI estimates for broad-leaved woody canopies using the software Can-Eye. Following the ISO 5725 protocol, we quantified the repeatability and reproducibility of the method, thus defining its precision for a wide range of broad-leaved canopies markedly differing for their structure. To get a complete evaluation of the method accuracy, we also quantified its trueness using artificial canopy images with known canopy cover. Moreover, the effect of the segmentation method was analysed. The best results for precision (restrained limits of repeatability and reproducibility) were obtained for high LAI values (>5) with limits corresponding to a variation of 22% in the estimated LAI values. Poorer results were obtained for medium and low LAI values, with a variation of the estimated LAI values that exceeded the 40%. Regardless of the LAI range explored, satisfactory results were achieved for trees in row-structured plantations (limits almost equal to the 30% of the estimated LAI). Satisfactory results were achieved for trueness, regardless of the canopy structure. The paired t-test revealed that the effect of the segmentation method on LAI estimates was significant. Despite a non negligible user effect, the accuracy metrics for DHP are consistent with those determined for other indirect methods for LAI estimates, confirming the overall reliability of DHP in broad-leaved woody canopies. PMID- 29596377 TI - A Novel Model to Simulate Flexural Complements in Compliant Sensor Systems. AB - The main challenge in analyzing compliant sensor systems is how to calculate the large deformation of flexural complements. Our study proposes a new model that is called the spline pseudo-rigid-body model (spline PRBM). It combines dynamic spline and the pseudo-rigid-body model (PRBM) to simulate the flexural complements. The axial deformations of flexural complements are modeled by using dynamic spline. This makes it possible to consider the nonlinear compliance of the system using four control points. Three rigid rods connected by two revolute (R) pins with two torsion springs replace the three lines connecting the four control points. The kinematic behavior of the system is described using Lagrange equations. Both the optimization and the numerical fitting methods are used for resolving the characteristic parameters of the new model. An example is given of a compliant mechanism to modify the accuracy of the model. The spline PRBM is important in expanding the applications of the PRBM to the design and simulation of flexural force sensors. PMID- 29596378 TI - Range Sensor-Based Efficient Obstacle Avoidance through Selective Decision Making. AB - In this paper, we address a collision avoidance method for mobile robots. Many conventional obstacle avoidance methods have been focused solely on avoiding obstacles. However, this can cause instability when passing through a narrow passage, and can also generate zig-zag motions. We define two strategies for obstacle avoidance, known as Entry mode and Bypass mode. Entry mode is a pattern for passing through the gap between obstacles, while Bypass mode is a pattern for making a detour around obstacles safely. With these two modes, we propose an efficient obstacle avoidance method based on the Expanded Guide Circle (EGC) method with selective decision-making. The simulation and experiment results show the validity of the proposed method. PMID- 29596379 TI - Natural Resistance Associated Macrophage Protein Is Involved in Immune Response of Blunt Snout Bream, Megalobrama amblycephala. AB - The natural resistance-associated macrophage protein gene (Nramp), has been identified as one of the significant candidate genes responsible for modulating vertebrate natural resistance to intracellular pathogens. Here, we identified and characterized a new Nramp family member, named as maNramp, in the blunt snout bream. The full-length cDNA of maNramp consists of a 153 bp 5'UTR, a 1635 bp open reading frame encoding a protein with 544 amino acids, and a 1359 bp 3'UTR. The deduced protein (maNRAMP) possesses the typical structural features of NRAMP protein family, including 12 transmembrane domains, three N-linked glycosylation sites, and a conserved transport motif. Phylogenetic analysis revealed that maNRAMP shares the significant sequence consistency with other teleosts, and shows the higher sequence similarity to mammalian Nramp2 than Nramp1. It was found that maNramp expressed ubiquitously in all normal tissues tested, with the highest abundance in the spleen, followed by the head kidney and intestine, and less abundance in the muscle, gill, and kidney. After lipopolysaccharide (LPS) stimulation, the mRNA level of maNramp was rapidly up-regulated, which reached a peak level at 6 h. Altogether, these results indicated that maNramp might be related to fish innate immunity and similar to mammalian Nramp1 in function. PMID- 29596380 TI - Reconsidering the Relationship between Air Pollution and Deprivation. AB - This paper critically examines the relationship between air pollution and deprivation. We argue that focusing on a particular economic or social model of urban development might lead one to erroneously expect all cities to converge towards a particular universal norm. A naive market sorting model, for example, would predict that poor households will eventually be sorted into high pollution areas, leading to a positive relationship between air pollution and deprivation. If, however, one considers a wider set of theoretical perspectives, the anticipated relationship between air pollution and deprivation becomes more complex and idiosyncratic. Specifically, we argue the relationship between pollution and deprivation can only be made sense of by considering processes of risk perception, path dependency, gentrification and urbanization. Rather than expecting all areas to eventually converge to some universal norm, we should expect the differences in the relationship between air pollution and deprivation across localities to persist. Mindful of these insights, we propose an approach to modeling which does not impose a geographically fixed relationship. Results for Scotland reveal substantial variations in the observed relationships over space and time, supporting our argument. PMID- 29596381 TI - Resveratrol Suppresses the Growth and Enhances Retinoic Acid Sensitivity of Anaplastic Thyroid Cancer Cells. AB - Anaplastic thyroid cancer (ATC) is a highly lethal undifferentiated malignancy without reliable therapies. Retinoic acid (RA) has been employed to promote redifferentiation of thyroid cancers by increasing their I131 uptake and radio sensitivity, but its effect(s) on ATCs has not yet been ascertained. Likewise, resveratrol induces cancer redifferentiation but, also in this case, its effects on ATCs remain unknown. These issues have been addresses in the current study using three human ATC cell lines (THJ-11T, THJ-16T, and THJ-21T) through multiple experimental approaches. The results reveal that RA exerts a small inhibitory effect on these cell lines. In comparison with normally cultured cells, the total cell number in resveratrol-treated THJ-16T and THJ-21T cultures significantly decreased (p < 0.05), and this effect was accompanied by reduced Cyclin D1 immuno labeling, increased apoptotic fractions, and distinct caspase-3 activation. Resveratrol failed to inhibit growth but enhanced RA sensitivity of THJ-11T cells, suppressed peroxisome proliferator-activated receptor-beta/delta (PPAR beta/delta), and upregulated cellular retinoic acid-binding protein 2 (CRABP2) and retinoic acid receptor beta (RAR-beta) expression. Increased thyroglobulin (Tg) and E-cadherin levels and appearance of membranous E-cadherin were evidenced in resveratrol-treated THJ-11T cells. Our results demonstrate for the first time: (1) the therapeutic value of resveratrol by itself or in combination with RA in the management of ATCs, (2) the capacity of resveratrol to overcome RA resistance in ATC cells by reprogramming CRABP2/RAR- and fatty acid-binding protein 5 (FABP5)/PPAR-beta/delta-mediated RA signaling, and (3) the redifferentiating potential of resveratrol in ATC cells. PMID- 29596382 TI - Mesenchymal Cells Affect Salivary Epithelial Cell Morphology on PGS/PLGA Core/Shell Nanofibers. AB - Engineering salivary glands is of interest due to the damaging effects of radiation therapy and the autoimmune disease Sjogren's syndrome on salivary gland function. One of the current problems in tissue engineering is that in vitro studies often fail to predict in vivo regeneration due to failure of cells to interact with scaffolds and of the single cell types that are typically used for these studies. Although poly (lactic co glycolic acid) (PLGA) nanofiber scaffolds have been used for in vitro growth of epithelial cells, PLGA has low compliance and cells do not penetrate the scaffolds. Using a core-shell electrospinning technique, we incorporated poly (glycerol sebacate) (PGS) into PLGA scaffolds to increase the compliance and decrease hydrophobicity. PGS/PLGA scaffolds promoted epithelial cell penetration into the scaffold and apical localization of tight junction proteins, which is necessary for epithelial cell function. Additionally, co-culture of the salivary epithelial cells with NIH3T3 mesenchymal cells on PGS/PLGA scaffolds facilitated epithelial tissue reorganization and apical localization of tight junction proteins significantly more than in the absence of the mesenchyme. These data demonstrate the applicability of PGS/PLGA nanofibers for epithelial cell self-organization and facilitation of co-culture cell interactions that promote tissue self-organization in vitro. PMID- 29596384 TI - Towards a Novel Patch Material for Cardiac Applications: Tissue-Specific Extracellular Matrix Introduces Essential Key Features to Decellularized Amniotic Membrane. AB - There is a growing need for scaffold material with tissue-specific bioactivity for use in regenerative medicine, tissue engineering, and for surgical repair of structural defects. We developed a novel composite biomaterial by processing human cardiac extracellular matrix (ECM) into a hydrogel and combining it with cell-free amniotic membrane via a dry-coating procedure. Cardiac biocompatibility and immunogenicity were tested in vitro using human cardiac fibroblasts, epicardial progenitor cells, murine HL-1 cells, and human immune cells derived from buffy coat. Processing of the ECM preserved important matrix proteins as demonstrated by mass spectrometry. ECM coating did not alter the mechanical characteristics of decellularized amniotic membrane but did cause a clear increase in adhesion capacity, cell proliferation and viability. Activated monocytes secreted less pro-inflammatory cytokines, and both macrophage polarization towards the pro-inflammatory M1 type and T cell proliferation were prevented. We conclude that the incorporation of human cardiac ECM hydrogel shifts and enhances the bioactivity of decellularized amniotic membrane, facilitating its use in future cardiac applications. PMID- 29596385 TI - Cigarette Waste in Popular Beaches in Thailand: High Densities that Demand Environmental Action. AB - Thailand, like all nations, has a responsibility to initiate environmental actions to preserve marine environments. Low- and middle-income countries face difficulties implementing feasible strategies to fulfill this ambitious goal. To contribute to the revitalization of Thailand's marine ecosystems, we investigated the level of tobacco product waste (TPW) on Thailand's public beaches. We conducted a cross-sectional observational survey at two popular public beaches. Research staff collected cigarette butts over two eight-hour days walking over a one-kilometer stretch of beach. We also compiled and analyzed data on butts collected from sieved sand at 11 popular beaches throughout Thailand's coast, with 10 samples of sieved sand collected per beach. Our survey at two beaches yielded 3067 butts in lounge areas, resulting in a mean butt density of 0.44/m2. At the 11 beaches, sieved sand samples yielded butt densities ranging from 0.25 to 13.3/m2, with a mean butt density of 2.26/m2 (SD = 3.78). These densities show that TPW has become a serious problem along Thailand's coastline. Our findings are comparable with those in other countries. We report on government and civil society initiatives in Thailand that are beginning to address marine TPW. The solution will only happen when responsible parties, especially and primarily tobacco companies, undertake actions to eliminate TPW. PMID- 29596383 TI - TASK-3 Downregulation Triggers Cellular Senescence and Growth Inhibition in Breast Cancer Cell Lines. AB - TASK-3 potassium channels are believed to promote proliferation and survival of cancer cells, in part, by augmenting their resistance to both hypoxia and serum deprivation. While overexpression of TASK-3 is frequently observed in cancers, the understanding of its role and regulation during tumorigenesis remains incomplete. Here, we evaluated the effect of reducing the expression of TASK-3 in MDA-MB-231 and MCF-10F human mammary epithelial cell lines through small hairpin RNA (shRNA)-mediated knockdown. Our results show that knocking down TASK-3 in fully transformed MDA-MB-231 cells reduces proliferation, which was accompanied by an induction of cellular senescence and cell cycle arrest, with an upregulation of cyclin-dependent kinase (CDK) inhibitors p21 and p27. In non tumorigenic MCF-10F cells, however, TASK-3 downregulation did not lead to senescence induction, although cell proliferation was impaired and an upregulation of CDK inhibitors was also evident. Our observations implicate TASK 3 as a critical factor in cell cycle progression and corroborate its potential as a therapeutic target in breast cancer treatment. PMID- 29596387 TI - Robust Sliding Mode Control of PMSM Based on a Rapid Nonlinear Tracking Differentiator and Disturbance Observer. AB - Torque ripples caused by cogging torque, flux harmonics, and current measurement error seriously restrict the application of a permanent magnet synchronous motor (PMSM), which has been paid more and more attention for the use in inertial stabilized platforms. Sliding mode control (SMC), in parallel with the classical proportional integral (PI) controller, has a high advantage to suppress the torque ripples as its invariance to disturbances. However, since the high switching gain tends to cause chattering and it requires derivative of signals which is not readily obtainable without an acceleration signal sensor. Therefore, this paper proposes a robust SMC scheme based on a rapid nonlinear tracking differentiator (NTD) and a disturbance observer (DOB) to further improve the performance of the SMC. The NTD is employed to providing the derivative of the signal, and the DOB is utilized to estimate the system lumped disturbances, including parameter variations and external disturbances. On the one hand, DOB can compensate the robust SMC speed controller, it can reduce the chattering of SMC on the other hand. Experiments were carried out on an ARM and DSP-based platform. The obtained experimental results demonstrate that the robust SMC scheme has an improved performance with inertia stability and it exhibits a satisfactory anti-disturbance performance compared to the traditional methods. PMID- 29596386 TI - The Role of Serotonin during Skin Healing in Post-Thermal Injury. AB - Post-burn trauma significantly raises tissue serotonin concentration at the initial stages of injury, which leads us to investigate its possible role in post burn wound healing. Therefore, we planned this study to examine the role of serotonin in wound healing through in vitro and in vivo models of burn injuries. Results from in vitro analysis revealed that serotonin decreased apoptosis and increased cell survival significantly in human fibroblasts and neonatal keratinocytes. Cellular proliferation also increased significantly in both cell types. Moreover, serotonin stimulation significantly accelerated the cell migration, resulting in narrowing of the scratch zone in human neonatal keratinocytes and fibroblasts cultures. Whereas, fluoxetine (a selective serotonin reuptake inhibitor) and ketanserin (serotonin receptor 2A inhibitor) reversed these effects. Scald burn mice model (20% total body surface area) showed that endogenous serotonin improved wound healing process in control group, whereas fluoxetine and ketanserin treatments (disruptors of endogenous serotonin stimulation), resulted in poor reepithelization, bigger wound size and high alpha smooth muscle actin (alpha-SMA) count. All of these signs refer a prolonged differentiation state, which ultimately exhibits poor wound healing outcomes. Collectively, data showed that the endogenous serotonin pathway contributes to regulating the skin wound healing process. Hence, the results of this study signify the importance of serotonin as a potential therapeutic candidate for enhancing skin healing in burn patients. PMID- 29596388 TI - Genetic Variants in STAT3 Promoter Regions and Their Application in Molecular Breeding for Body Size Traits in Qinchuan Cattle. AB - Signal transducer and activator of transcription 3 (STAT3) plays a critical role in leptin-mediated regulation of energy metabolism. This study investigated genetic variation in STAT3 promoter regions and verified their contribution to bovine body size traits. We first estimated the degree of conservation in STAT3, followed by measurements of its mRNA expression during fetal and adult stages of Qinchuan cattle. We then sequenced the STAT3 promoter region to determine genetic variants and evaluate their association with body size traits. From fetus to adult, STAT3 expression increased significantly in muscle, fat, heart, liver, and spleen tissues (p < 0.01), but decreased in the intestine, lung, and rumen (p < 0.01). We identified and named five single nucleotide polymorphisms (SNPs): SNP1 304A>C, SNP2-285G>A, SNP3-209A>C, SNP4-203A>G, and SNP5-188T>C. These five mutations fell significantly outside the Hardy-Weinberg equilibrium (HWE) (Chi squared test, p < 0.05) and significantly associated with body size traits (p < 0.05). Individuals with haplotype H3H3 (CC-GG-CC-GG-CC) were larger in body size than other haplotypes. Therefore, variations in the STAT3 gene promoter regions, most notably haplotype H3H3, may benefit marker-assisted breeding of Qinchuan cattle. PMID- 29596389 TI - Enteric Virus Diversity Examined by Molecular Methods in Brazilian Poultry Flocks. AB - Enteric viruses play an important role in the Brazilian poultry industry due to the economic impact of resulting low yields of broilers, layers, and breeders. The most common enteric viruses affecting commercial flocks in Brazil include Fowl Adenovirus of group I (FAdV-I), Chicken Parvovirus (ChPV), Chicken Astrovirus (CAstV), Avian Nephritis Virus (ANV), Infectious Bronchitis Virus (IBV), Avian Reovirus (AReo), and Avian Rotavirus (ARtV). The aim of this study was to identify single and multiple infections using data obtained from 270 samples from eleven Brazilian states, corresponding to the period between 2010 and 2017. This was accompanied by an analysis of the relationship between the age of birds, clinical signs, and geographical distribution, using Polymerase Chain Reaction (PCR) and Reverse Transcription-PCR (RT-PCR) techniques. Twenty-five profiles of virus combinations were detected. Single infections were encountered in 86.3% of samples, and multiple infections were present in the remaining 13.7%. Both single and multiple infections affected all kinds of commercial chickens with digestive problems, stunting syndrome, decreases in egg and meat production, increased mortality, and respiratory signs. FAdV-I, ChPV, CAstV, ANV, and ARtV were mostly detected in young broilers, in contrast with IBV, which was detected in hens from one to greater than 51 weeks of age. These results exhibit the complexity of enteric diseases and the still poorly understood role of each pathogen as a unique etiological agent. PMID- 29596390 TI - The Effects of Plant-Derived Oleanolic Acid on Selected Parameters of Glucose Homeostasis in a Diet-Induced Pre-Diabetic Rat Model. AB - Prolonged exposure to high energy diets has been implicated in the development of pre-diabetes, a long-lasting condition that precedes type 2 diabetes mellitus (T2DM). A combination of pharmacological and dietary interventions is used to prevent the progression of pre-diabetes to T2DM. However, poor patient compliance leads to negligence of the dietary intervention and thus reduced drug efficiency. Oleanolic acid (OA) has been reported to possess anti-diabetic effects in type 1 diabetic rats. However, the effects of this compound on pre-diabetes have not yet been established. Consequently, this study sought to evaluate the effects OA on a diet-induced pre-diabetes rat model. Pre-diabetic male Sprague Dawley rats were treated with OA in both the presence and absence of dietary intervention for a period of 12 weeks. The administration of OA with and without dietary intervention resulted in significantly improved glucose homeostasis through reduced caloric intake, body weights, plasma ghrelin concentration and glycated haemoglobin by comparison to the pre-diabetic control. These results suggest that OA may be used to manage pre-diabetes as it was able to restore glucose homeostasis and prevented the progression to overt type 2 diabetes. PMID- 29596392 TI - Optimally Distributed Kalman Filtering with Data-Driven Communication. AB - For multisensor data fusion, distributed state estimation techniques that enable a local processing of sensor data are the means of choice in order to minimize storage and communication costs. In particular, a distributed implementation of the optimal Kalman filter has recently been developed. A significant disadvantage of this algorithm is that the fusion center needs access to each node so as to compute a consistent state estimate, which requires full communication each time an estimate is requested. In this article, different extensions of the optimally distributed Kalman filter are proposed that employ data-driven transmission schemes in order to reduce communication expenses. As a first relaxation of the full-rate communication scheme, it can be shown that each node only has to transmit every second time step without endangering consistency of the fusion result. Also, two data-driven algorithms are introduced that even allow for lower transmission rates, and bounds are derived to guarantee consistent fusion results. Simulations demonstrate that the data-driven distributed filtering schemes can outperform a centralized Kalman filter that requires each measurement to be sent to the center node.

AB - This work reviews the field of screen-printed electrodes (SPEs) modified with "green" metals for electrochemical stripping analysis of toxic elements. Electrochemical stripping analysis has been established as a useful trace analysis technique offering many advantages compared to competing optical techniques. Although mercury has been the preferred electrode material for stripping analysis, the toxicity of mercury and the associated legal requirements in its use and disposal have prompted research towards the development of "green" metals as alternative electrode materials. When combined with the screen-printing technology, such environment-friendly metals can lead to disposable sensors for trace metal analysis with excellent operational characteristics. This review focuses on SPEs modified with Au, Bi, Sb, and Sn for stripping analysis of toxic elements. Different modification approaches (electroplating, bulk modification, use of metal precursors, microengineering techniques) are considered and representative applications are described. A developing related field, namely biosensing based on stripping analysis of metallic nanoprobe labels, is also briefly mentioned.

AB - In this paper, we proposed a novel object-based dense matching method specially for the high-precision disparity map of building objects in urban areas, which can maintain accurate object structure characteristics. The proposed framework mainly includes three stages. Firstly, an improved edge line extraction method is proposed for the edge segments to fit closely to building outlines. Secondly, a fusion method is proposed for the outlines under the constraint of straight lines, which can maintain the building structural attribute with parallel or vertical edges, which is very useful for the dense matching method. Finally, we proposed an edge constraint and outline compensation (ECAOC) dense matching method to maintain building object structural characteristics in the disparity map. In the proposed method, the improved edge lines are used to optimize matching search scope and matching template window, and the high-precision building outlines are used to compensate the shape feature of building objects. Our method can greatly increase the matching accuracy of building objects in urban areas, especially at building edges. For the outline extraction experiments, our fusion method verifies the superiority and robustness on panchromatic images of different satellites and different resolutions. For the dense matching experiments, our ECOAC method shows great advantages for matching accuracy of building objects in urban areas compared with three other methods. PMID- 29596394 TI - Real-Time Processing Library for Open-Source Hardware Biomedical Sensors. AB - Applications involving data acquisition from sensors need samples at a preset frequency rate, the filtering out of noise and/or analysis of certain frequency components. We propose a novel software architecture based on open-software hardware platforms which allows programmers to create data streams from input channels and easily implement filters and frequency analysis objects. The performances of the different classes given in the size of memory allocated and execution time (number of clock cycles) were analyzed in the low-cost platform Arduino Genuino. In addition, 11 people took part in an experiment in which they had to implement several exercises and complete a usability test. Sampling rates under 250 Hz (typical for many biomedical applications) makes it feasible to implement filters, sliding windows and Fourier analysis, operating in real time. Participants rated software usability at 70.2 out of 100 and the ease of use when implementing several signal processing applications was rated at just over 4.4 out of 5. Participants showed their intention of using this software because it was percieved as useful and very easy to use. The performances of the library showed that it may be appropriate for implementing small biomedical real-time applications or for human movement monitoring, even in a simple open-source hardware device like Arduino Genuino. The general perception about this library is that it is easy to use and intuitive. PMID- 29596395 TI - Effect of Early-Life Treatment of Piglets with Long-Acting Ceftiofur on Colonization of Streptococcus suis Serotype 7 and Elicitation of Specific Humoral Immunity in a Farm Dealing with Streptococcal Diseases. AB - In newborn piglets treatment with long-acting ceftiofur is a common approach to reduce losses due to streptococcal diseases on farms, even if problems start after weaning. The purpose of this study was to examine the influence of a single early-life treatment on Streptococcus (S.) suis colonization, transmission, immunoreaction, and drug resistance over an observation period of 14 weeks. In a farm with a history of streptococcal disease and isolation of a S. suis cps 7 mrp+, arcA+ isolate from diseased piglets, half of each litter was treated with a long-acting ceftiofur on day 1. S. suis-isolates were profiled and serum samples were tested for opsonizing antibodies. Treated and untreated pigs did not differ according to average daily weight gains, S. suis-isolation rates and level of opsonizing antibodies. Although the invasive cps 7 strain was not detected in a single piglet over 14 weeks, all animals developed bactericidal activity. No resistance to ceftiofur, but resistance to tetracyclins (100%), and trimethoprim/sulfamethoxazole (53%) was shown. Our results indicate that early treatment with ceftiofur does not prevent colonization and transmission of S. suis or the induction of bactericidal humoral immunity in nursery and fattening pigs. The necessity of continuous usage should be reconsidered. PMID- 29596396 TI - Smart Garment Fabrics to Enable Non-Contact Opto-Physiological Monitoring. AB - Imaging photoplethysmography (iPPG) is an emerging technology used to assess microcirculation and cardiovascular signs by collecting backscattered light from illuminated tissue using optical imaging sensors. The aim of this study was to study how effective smart garment fabrics could be capturing physiological signs in a non-contact mode. The present work demonstrates a feasible approach of, instead of using conventional high-power illumination sources, integrating a grid of surface-mounted light emitting diodes (LEDs) into cotton fabric to spotlight the region of interest (ROI). The green and the red LEDs (525 and 660 nm) placed on a small cotton substrate were used to locally illuminate palm skin in a dual wavelength iPPG setup, where the backscattered light is transmitted to a remote image sensor through the garment fabric. The results show that the illuminations from both wavelength LEDs can be used to extract heart rate (HR) reaching an accuracy of 90% compared to a contact PPG probe. Stretching the fabric over the skin surface alters the morphology of iPPG signals, demonstrating a significantly higher pulsatile amplitude in both channels of green and red illuminations. The skin compression by the fabric could be potentially utilised to enhance the penetration of illumination into cutaneous microvascular beds. The outcome could lead a new avenue of non-contact opto-physiological monitoring and assessment with functional garment fabrics. PMID- 29596397 TI - Vehicle Mode and Driving Activity Detection Based on Analyzing Sensor Data of Smartphones. AB - In this paper, we present a flexible combined system, namely the Vehicle mode driving Activity Detection System (VADS), that is capable of detecting either the current vehicle mode or the current driving activity of travelers. Our proposed system is designed to be lightweight in computation and very fast in response to the changes of travelers' vehicle modes or driving events. The vehicle mode detection module is responsible for recognizing both motorized vehicles, such as cars, buses, and motorbikes, and non-motorized ones, for instance, walking, and bikes. It relies only on accelerometer data in order to minimize the energy consumption of smartphones. By contrast, the driving activity detection module uses the data collected from the accelerometer, gyroscope, and magnetometer of a smartphone to detect various driving activities, i.e., stopping, going straight, turning left, and turning right. Furthermore, we propose a method to compute the optimized data window size and the optimized overlapping ratio for each vehicle mode and each driving event from the training datasets. The experimental results show that this strategy significantly increases the overall prediction accuracy. Additionally, numerous experiments are carried out to compare the impact of different feature sets (time domain features, frequency domain features, Hjorth features) as well as the impact of various classification algorithms (Random Forest, Naive Bayes, Decision tree J48, K Nearest Neighbor, Support Vector Machine) contributing to the prediction accuracy. Our system achieves an average accuracy of 98.33% in detecting the vehicle modes and an average accuracy of 98.95% in recognizing the driving events of motorcyclists when using the Random Forest classifier and a feature set containing time domain features, frequency domain features, and Hjorth features. Moreover, on a public dataset of HTC company in New Taipei, Taiwan, our framework obtains the overall accuracy of 97.33% that is considerably higher than that of the state-of the art. PMID- 29596398 TI - Ultra Uniform Pb0.865La0.09(Zr0.65Ti0.35)O3 Thin Films with Tunable Optical Properties Fabricated via Pulsed Laser Deposition. AB - Ferroelectric thin films have been utilized in a wide range of electronic and optical applications, in which their morphologies and properties can be inherently tuned by a qualitative control during growth. In this work, we demonstrate the evolution of the Pb0.865La0.09(Zr0.65Ti0.35)O3 (PLZT) thin films on MgO (200) with high uniformity and optimized optical property via the controls of the deposition temperatures and oxygen pressures. The perovskite phase can only be obtained at the deposition temperature above 700 degrees C and oxygen pressure over 50 Pa due to the improved crystallinity. Meanwhile, the surface morphologies gradually become smooth and compact owing to spontaneously increased nucleation sites with the elevated temperatures, and the crystallization of PLZT thin films also sensitively respond to the oxygen vacancies with the variation of oxygen pressures. Correspondingly, the refractive indices gradually develop with variations of the deposition temperatures and oxygen pressures resulted from the various slight loss, and the extinction coefficient for each sample is similarly near to zero due to the relatively smooth morphology. The resulting PLZT thin films exhibit the ferroelectricity, and the dielectric constant sensitively varies as a function of electric filed, which can be potentially applied in the electronic and optical applications. PMID- 29596399 TI - Bioinformatic Analysis of GLI1 and Related Signaling Pathways in Chemosensitivity of Gastric Cancer. AB - BACKGROUND This study assessed the prognostic value of GLI1 in gastric cancer and analyzed the possible GLI1-related signaling network in chemosensitivity. MATERIAL AND METHODS Bioinformatic data mining was performed by using data in the TCGA-Stomach Cancer (TCGA-STAD) and the Kaplan-Meier plotter. GLI1 co-expressed genes in TCGA-STAD were subjected to KEGG pathway analysis. The genes enriched in the KEGG pathways were further subjected to Protein-Protein Interaction (PPI) analysis. RESULTS In TCGA-STAD, high GLI1 gene/exon expression was associated with significantly worse survival (p=0.016 and 0.0023 respectively). In the Kaplan-Meier plotter, high GLI1 expression was associated with unfavorable overall survival (OS) (HR: 1.68, 95%CI: 1.42-2, p<0.0001) and first progression free survival (FPS) (HR: 1.72, 95%CI: 1.4-2.11, p<0.0001). In TCGA-STAD, 600 GLI1 co-expressed genes were identified (absolute Pearson's r >=0.5). The most significant pathways were pathways in cancer (p=230.0E-12) and the Hedgehog signaling pathway (p=6.9E-9). PI3K-AKT pathway (p=17.0E-9) has the largest proportion of gene enrichment. Some GLI1 co-expressed genes in the PI3K-AKT pathway are central nodes in the PPI network and also play important roles in chemosensitivity of gastric cancer. Nevertheless, the mechanisms underlying their co-expression are still largely unexplored. CONCLUSIONS High GLI1 expression is associated with unfavorable OS and FPS in patients with gastric cancer. As a member of the Hedgehog signaling pathway, GLI1 co-expressed genes are also largely enriched in PI3K/AKT pathway in gastric cancer, which is closely related to chemoresistance. The underlying mechanisms are still largely unexplored and need further study.

PMID- 29596400 TI - Trends in Diabetic Ketoacidosis Hospitalizations and In-Hospital Mortality - United States, 2000-2014. AB - Diabetes is a common chronic condition and as of 2015, approximately 30 million persons in the United States had diabetes (23 million with diagnosed and 7 million with undiagnosed) (1). Diabetic ketoacidosis (DKA) is a life-threatening but preventable complication of diabetes characterized by uncontrolled hyperglycemia (>250 mg/dL), metabolic acidosis, and increased ketone concentration that occurs most frequently in persons with type 1 diabetes (2). CDC's United States Diabetes Surveillance System* (USDSS) indicated an increase in hospitalization rates for DKA during 2009-2014, most notably in persons aged <45 years. To explore this finding, 2000-2014 data from the Agency for Healthcare Research and Quality's National Inpatient Sample (NIS)? were assembled to calculate trends in DKA hospitalization rates and in-hospital case-fatality rates. Overall, age-adjusted DKA hospitalization rates decreased slightly from 2000 to 2009, then reversed direction, steadily increasing from 2009 to 2014 at an average annual rate of 6.3%. In-hospital case-fatality rates declined consistently during the study period from 1.1% to 0.4%. Better understanding the causes of this increasing trend in DKA hospitalizations and decreasing trend in in-hospital case-fatality through further exploration using multiple data sources will facilitate the targeting of prevention efforts. PMID- 29596402 TI - Prevalence of Diagnosed Diabetes in Adults by Diabetes Type - United States, 2016. AB - Currently 23 million U.S. adults have been diagnosed with diabetes (1). The two most common forms of diabetes are type 1 and type 2. Type 1 diabetes results from the autoimmune destruction of the pancreas's beta cells, which produce insulin. Persons with type 1 diabetes require insulin for survival; insulin may be given as a daily shot or continuously with an insulin pump (2). Type 2 diabetes is mainly caused by a combination of insulin resistance and relative insulin deficiency (3). A small proportion of diabetes cases might be types other than type 1 or type 2, such as maturity-onset diabetes of the young or latent autoimmune diabetes in adults (3). Although the majority of prevalent cases of type 1 and type 2 diabetes are in adults, national data on the prevalence of type 1 and type 2 in the U.S. adult population are sparse, in part because of the previous difficulty in classifying diabetes by type in surveys (2,4,5). In 2016, supplemental questions to help distinguish diabetes type were added to the National Health Interview Survey (NHIS) (6). This study used NHIS data from 2016 to estimate the prevalence of diagnosed diabetes among adults by primary type. Overall, based on self-reported type and current insulin use, 0.55% of U.S. adults had diagnosed type 1 diabetes, representing 1.3 million adults; 8.6% had diagnosed type 2 diabetes, representing 21.0 million adults. Of all diagnosed cases, 5.8% were type 1 diabetes, and 90.9% were type 2 diabetes; the remaining 3.3% of cases were other types of diabetes. Understanding the prevalence of diagnosed diabetes by type is important for monitoring trends, planning public health responses, assessing the burden of disease for education and management programs, and prioritizing national plans for future type-specific health services.

AB - On April 26, 2015, a case of meningococcal disease in a woman aged 75 years was reported to the Colorado Department of Public Health and Environment (CDPHE). As part of routine public health investigation and control activities, all seven family contacts of the patient were advised to receive appropriate postexposure prophylaxis (PEP) to eradicate nasopharyngeal carriage of meningococci and prevent secondary disease (1), although it is not known whether the family contacts complied with PEP recommendations. Fifteen months later, on June 6, 2016, CDPHE was notified that the grandchild of the first patient, a male infant aged 3 months who lived with the first patient, also had meningococcal disease. The infant's immediate family members (parents and one sibling) were among family contacts for whom PEP was recommended in 2015. Neisseria meningitidis isolates from both patients were found to be serogroup C at the CDPHE laboratory. Whole genome sequence (WGS) analysis at CDC found that both isolates had the same sequence type, indicating close genetic relatedness. These cases represent a possible instance of meningococcal disease transmission within a family, despite appropriate PEP recommendations and with a long interval between cases. PMID- 29596405 TI - Overdose Deaths Involving Opioids, Cocaine, and Psychostimulants - United States, 2015-2016. AB - During 1999-2015, 568,699 persons died from drug overdoses in the United States.* Drug overdose deaths in the United States increased 11.4% from 2014 to 2015 resulting in 52,404 deaths in 2015, including 33,091 (63.1%) that involved an opioid. The largest rate increases from 2014 to 2015 occurred among deaths involving synthetic opioids other than methadone (synthetic opioids) (72.2%) (1). Because of demographic and geographic variations in overdose deaths involving different drugs (2,3),? CDC examined age-adjusted death rates for overdoses involving all opioids, opioid subcategories (i.e., prescription opioids, heroin, and synthetic opioids),S cocaine, and psychostimulants with abuse potential (psychostimulants) by demographics, urbanization levels, and in 31 states and the District of Columbia (DC). There were 63,632 drug overdose deaths in 2016; 42,249 (66.4%) involved an opioid. From 2015 to 2016, deaths increased across all drug categories examined. The largest overall rate increases occurred among deaths involving cocaine (52.4%) and synthetic opioids (100%), likely driven by illicitly manufactured fentanyl (IMF) (2,3). Increases were observed across demographics, urbanization levels, and states and DC. The opioid overdose epidemic in the United States continues to worsen. A multifaceted approach, with faster and more comprehensive surveillance, is needed to track emerging threats to prevent and respond to the overdose epidemic through naloxone availability, safe prescribing practices, harm-reduction services, linkage into treatment, and more collaboration between public health and public safety agencies. PMID- 29596407 TI - Notes from the Field: Fatalities Associated with Human Adenovirus Type 7 at a Substance Abuse Rehabilitation Facility - New Jersey, 2017. PMID- 29596406 TI - Heart Disease Death Rates Among Blacks and Whites Aged >=35 Years - United States, 1968-2015. AB - PROBLEM/CONDITION: Heart disease is the leading cause of death in the United States. In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths in the United States. Although heart disease death rates decreased 68% for the total population from 1968 to 2015, marked disparities in decreases exist by race and state. PERIOD COVERED: 1968-2015. DESCRIPTION OF SYSTEM: The National Vital Statistics System (NVSS) data on deaths in the United States were abstracted for heart disease using diagnosis codes from the eighth, ninth, and tenth revisions of the International Classification of Diseases (ICD-8, ICD-9, and ICD-10) for 1968-2015. Population estimates were obtained from NVSS files. National and state-specific heart disease death rates for the total population and by race for adults aged >=35 years were calculated for 1968-2015. National and state-specific black-white heart disease mortality ratios also were calculated. Death rates were age standardized to the 2000 U.S. standard population. Joinpoint regression was used to perform time trend analyses. RESULTS: From 1968 to 2015, heart disease death rates decreased for the total U.S. population among adults aged >=35 years, from 1,034.5 to 327.2 per 100,000 population, respectively, with variations in the magnitude of decreases by race and state. Rates decreased for the total population an average of 2.4% per year, with greater average decreases among whites (2.4% per year) than blacks (2.2% per year). At the national level, heart disease death rates for blacks and whites were similar at the start of the study period (1968) but began to diverge in the late 1970s, when rates for blacks plateaued while rates for whites continued to decrease. Heart disease death rates among blacks remained higher than among whites for the remainder of the study period. Nationwide, the black white ratio of heart disease death rates increased from 1.04 in 1968 to 1.21 in 2015, with large increases occurring during the 1970s and 1980s followed by small but steady increases until approximately 2005. Since 2005, modest decreases have occurred in the black-white ratio of heart disease death rates at the national level. The majority of states had increases in black-white mortality ratios from 1968 to 2015. The number of states with black-white mortality ratios >1 increased from 16 (40%) to 27 (67.5%). INTERPRETATION: Although heart disease death rates decreased both for blacks and whites from 1968 to 2015, substantial differences in decreases were found by race and state. At the national level and in most states, blacks experienced smaller decreases in heart disease death rates than whites for the majority of the period. Overall, the black-white disparity in heart disease death rates increased from 1968 to 2005, with a modest decrease from 2005 to 2015. PUBLIC HEALTH ACTION: Since 1968, substantial increases have occurred in black-white disparities of heart disease death rates in the United States at the national level and in many states. These increases appear to be due to faster decreases in heart disease death rates for whites than blacks, particularly from the late 1970s until the mid-2000s. Despite modest decreases in black-white disparities at the national level since 2005, in 2015, heart disease death rates were 21% higher among blacks than among whites. This study demonstrates the use of NVSS data to conduct surveillance of heart disease death rates by race and of black-white disparities in heart disease death rates. Continued surveillance of temporal trends in heart disease death rates by race can provide valuable information to policy makers and public health practitioners working to reduce heart disease death rates both for blacks and whites and disparities between blacks and whites.

PMID- 29596409 TI - Distinct inflammatory profile underlies pathological increases in creatinine levels associated with Plasmodium vivax malaria clinical severity. AB - BACKGROUND: Although Plasmodium vivax infection is a frequent cause of malaria worldwide, severe presentations have been more regularly described only in recent years. In this setting, despite clinical descriptions of multi-organ involvement, data associating it with kidney dysfunction are relatively scarce. Here, renal dysfunction is retrospectively analyzed in a large cohort of vivax malaria patients with an attempt to dissect its association with disease severity and mortality, and to determine the role of inflammation in its progression. METHODS: A retrospective analysis of a databank containing 572 individuals from the Brazilian Amazon, including 179 patients with P. vivax monoinfection (161 symptomatic malaria, 12 severe non-lethal malaria, and 6 severe lethal disease) and 165 healthy controls, was performed. Data on levels of cytokines, chemokines, C-reactive protein (CRP), fibrinogen, creatinine, hepatic enzymes, bilirubin levels, free heme, and haptoglobin were analyzed to depict and compare profiles from patients per creatinine levels. RESULTS: Elevated creatinine levels were found predominantly in women. Vivax malaria severity was highly associated with abnormal creatinine increases, and nonsurvivors presented the highest values of serum creatinine. Indication of kidney dysfunction was not associated with parasitemia levels. IFN-gamma/IL-10 ratio and CRP values marked the immune biosignature of vivax malaria patients, and could distinguish subjects with elevated creatinine levels who did not survive from those who did. Patients with elevated serum creatinine or severe vivax malaria displayed indication of cholestasis. Biomarkers of hemolysis did not follow increases in serum creatinine. CONCLUSION: These findings reinforce the hypothesis that renal dysfunction is a key component in P. vivax malaria associated with clinical severity and mortality, possibly through intense inflammation and immune imbalance. Our study argues for systematic evaluation of kidney function as part of the clinical assessment in vivax malaria patients, and warrants additional studies in experimental models for further mechanism investigations. PMID- 29596410 TI - Identifying off-target effects of etomoxir reveals that carnitine palmitoyltransferase I is essential for cancer cell proliferation independent of beta-oxidation. AB - It has been suggested that some cancer cells rely upon fatty acid oxidation (FAO) for energy. Here we show that when FAO was reduced approximately 90% by pharmacological inhibition of carnitine palmitoyltransferase I (CPT1) with low concentrations of etomoxir, the proliferation rate of various cancer cells was unaffected. Efforts to pharmacologically inhibit FAO more than 90% revealed that high concentrations of etomoxir (200 MUM) have an off-target effect of inhibiting complex I of the electron transport chain. Surprisingly, however, when FAO was reduced further by genetic knockdown of CPT1, the proliferation rate of these same cells decreased nearly 2-fold and could not be restored by acetate or octanoic acid supplementation. Moreover, CPT1 knockdowns had altered mitochondrial morphology and impaired mitochondrial coupling, whereas cells in which CPT1 had been approximately 90% inhibited by etomoxir did not. Lipidomic profiling of mitochondria isolated from CPT1 knockdowns showed depleted concentrations of complex structural and signaling lipids. Additionally, expression of a catalytically dead CPT1 in CPT1 knockdowns did not restore mitochondrial coupling. Taken together, these results suggest that transport of at least some long-chain fatty acids into the mitochondria by CPT1 may be required for anabolic processes that support healthy mitochondrial function and cancer cell proliferation independent of FAO. PMID- 29596411 TI - Common occurrence of Cryptosporidium hominis in asymptomatic and symptomatic calves in France. AB - BACKGROUND: Cryptosporidium spp. infections are the most frequent parasitic cause of diarrhea in humans and cattle. However, asymptomatic cases are less often documented than symptomatic cases or cases with experimentally infected animals. Cryptosporidium (C.) hominis infection accounts for the majority of pediatric cases in several countries, while C. parvum is a major cause of diarrhea in neonatal calves. In cattle Cryptosporidium spp. infection can be caused by C. parvum, C. bovis, C.andersoni and C. ryanae, and recently, reports of cattle cases of C. hominis cryptosporidiosis cases suggest that the presence of C. hominis in calves was previously underestimated. METHODOLOGY/PRINCIPAL FINDINGS: From February to November 2015, Cryptosporidium spp. infected calves were detected in 29/44 randomly included farms from 5 geographic regions of France. C. hominis and C. parvum were found in 12/44 and 26/44 farms, respectively with higher C. hominis prevalence in the western region. In 9 farms, both C. parvum and C. hominis were detected. Eighty-six of 412 (73/342 asymptomatic and 13/70 symptomatic) one to nine-week-old calves shed C. hominis or C. parvum oocysts (15 and 71 calves, respectively), with no mixed infection detected. The predominant C. hominis IbA9G3 genotype was present in all regions, and more frequent in the western region. An incompletely characterized Ib, and the IbA13G3, IbA9G2 and IbA14G2 genotypes were present only in the western region. For C. parvum, the most frequent genotype was IIaA16G3R1 with no geographic clustering. Most C. hominis infected calves were asymptomatic, with some exceptions of IbA9G2 and IbA9G3 isolates, while C. parvum IIaA16G3R1 was associated with symptoms. CONCLUSIONS/SIGNIFICANCE: Present results indicate for the first time that in several geographic regions of France, C. hominis was present in about one fifth of both asymptomatic and symptomatic infected calves, with isolated genotypes likely associated with human infection. Further investigations are aimed at documenting direct or indirect transmissions between livestock and humans. PMID- 29596412 TI - Development and evaluation of antibody-capture immunoassays for detection of Lassa virus nucleoprotein-specific immunoglobulin M and G. AB - BACKGROUND: The classical method for detection of Lassa virus-specific antibodies is the immunofluorescence assay (IFA) using virus-infected cells as antigen. However, IFA requires laboratories of biosafety level 4 for assay production and an experienced investigator to interpret the fluorescence signals. Therefore, we aimed to establish and evaluate enzyme-linked immunosorbent assays (ELISA) using recombinant Lassa virus nucleoprotein (NP) as antigen. METHODOLOGY/PRINCIPAL FINDINGS: The IgM ELISA is based on capturing IgM antibodies using anti-IgM, and the IgG ELISA is based on capturing IgG antibody-antigen complexes using rheumatoid factor or Fc gamma receptor CD32a. Analytical and clinical evaluation was performed with 880 sera from Lassa fever endemic (Nigeria) and non-endemic (Ghana and Germany) areas. Using the IFA as reference method, we observed 91.5 94.3% analytical accuracy of the ELISAs in detecting Lassa virus-specific antibodies. Evaluation of the ELISAs for diagnosis of Lassa fever on admission to hospital in an endemic area revealed a clinical sensitivity for the stand-alone IgM ELISA of 31% (95% CI 25-37) and for combined IgM/IgG detection of 26% (95% CI 21-32) compared to RT-PCR. The specificity of IgM and IgG ELISA was estimated at 96% (95% CI 93-98) and 100% (95% CI 99-100), respectively, in non-Lassa fever patients from non-endemic areas. In patients who seroconverted during follow-up, Lassa virus-specific IgM and IgG developed simultaneously rather than sequentially. Consistent with this finding, isolated IgM reactivity, i.e. IgM in the absence of IgG, had no diagnostic value. CONCLUSIONS/SIGNIFICANCE: The ELISAs are not equivalent to RT-PCR for early diagnosis of Lassa fever; however, they are of value in diagnosing patients at later stage. The IgG ELISA may be useful for epidemiological studies and clinical trials due its high specificity, and the higher throughput rate and easier operation compared to IFA. PMID- 29596413 TI - Lack of 2'-O-methylation in the tRNA anticodon loop of two phylogenetically distant yeast species activates the general amino acid control pathway. AB - Modification defects in the tRNA anticodon loop often impair yeast growth and cause human disease. In the budding yeast Saccharomyces cerevisiae and the phylogenetically distant fission yeast Schizosaccharomyces pombe, trm7Delta mutants grow poorly due to lack of 2'-O-methylation of C32 and G34 in the tRNAPhe anticodon loop, and lesions in the human TRM7 homolog FTSJ1 cause non-syndromic X linked intellectual disability (NSXLID). However, it is unclear why trm7Delta mutants grow poorly. We show here that despite the fact that S. cerevisiae trm7Delta mutants had no detectable tRNAPhe charging defect in rich media, the cells constitutively activated a robust general amino acid control (GAAC) response, acting through Gcn2, which senses uncharged tRNA. Consistent with reduced available charged tRNAPhe, the trm7Delta growth defect was suppressed by spontaneous mutations in phenylalanyl-tRNA synthetase (PheRS) or in the pol III negative regulator MAF1, and by overexpression of tRNAPhe, PheRS, or EF-1A; all of these also reduced GAAC activation. Genetic analysis also demonstrated that the trm7Delta growth defect was due to the constitutive robust GAAC activation as well as to the reduced available charged tRNAPhe. Robust GAAC activation was not observed with several other anticodon loop modification mutants. Analysis of S. pombe trm7 mutants led to similar observations. S. pombe Trm7 depletion also resulted in no observable tRNAPhe charging defect and a robust GAAC response, and suppressors mapped to PheRS and reduced GAAC activation. We speculate that GAAC activation is widely conserved in trm7 mutants in eukaryotes, including metazoans, and might play a role in FTSJ1-mediated NSXLID.

A burgeoning number of scientific leaders believe the current system of faculty incentives and rewards is misaligned with the needs of society and disconnected from the evidence about the causes of the reproducibility crisis and suboptimal quality of the scientific publication record. To address this issue, particularly for the clinical and life sciences, we convened a 22-member expert panel workshop in Washington, DC, in January 2017. Twenty-two academic leaders, funders, and scientists participated in the meeting. As background for the meeting, we completed a selective literature review of 22 key documents critiquing the current incentive system. From each document, we extracted how the authors perceived the problems of assessing science and scientists, the unintended consequences of maintaining the status quo for assessing scientists, and details of their proposed solutions. The resulting table was used as a seed for participant discussion. This resulted in six principles for assessing scientists and associated research and policy implications. We hope the content of this paper will serve as a basis for establishing best practices and redesigning the current approaches to assessing scientists by the many players involved in that process.

AB - Cloud computing has revolutionized the development and operations of hardware and software across diverse technological arenas, yet academic biomedical research has lagged behind despite the numerous and weighty advantages that cloud computing offers. Biomedical researchers who embrace cloud computing can reap rewards in cost reduction, decreased development and maintenance workload, increased reproducibility, ease of sharing data and software, enhanced security, horizontal and vertical scalability, high availability, a thriving technology partner ecosystem, and much more. Despite these advantages that cloud-based workflows offer, the majority of scientific software developed in academia does not utilize cloud computing and must be migrated to the cloud by the user. In this article, we present 11 quick tips for architecting biomedical informatics workflows on compute clouds, distilling knowledge gained from experience developing, operating, maintaining, and distributing software and virtualized appliances on the world's largest cloud. Researchers who follow these tips stand to benefit immediately by migrating their workflows to cloud computing and embracing the paradigm of abstraction.

AB - Pinaceae, the largest family of conifers, has a diversified organization of chloroplast (cp) genomes with two typical highly reduced inverted repeats (IRs). In the current study, we determined the complete sequence of the cp genome of an economically and ecologically important conifer tree, the loblolly pine (Pinus taeda L.), using Illumina paired-end sequencing and compared the sequence with those of other pine species. The results revealed a genome size of 121,531 base pairs (bp) containing a pair of 830-bp IR regions, distinguished by a small single copy (42,258 bp) and large single copy (77,614 bp) region. The chloroplast genome of P. taeda encodes 120 genes, comprising 81 protein-coding genes, four ribosomal RNA genes, and 35 tRNA genes, with 151 randomly distributed microsatellites. Approximately 6 palindromic, 34 forward, and 22 tandem repeats were found in the P. taeda cp genome. Whole cp genome comparison with those of other Pinus species exhibited an overall high degree of sequence similarity, with some divergence in intergenic spacers. Higher and lower numbers of indels and single-nucleotide polymorphism substitutions were observed relative to P. contorta and P. monophylla, respectively. Phylogenomic analyses based on the complete genome sequence revealed that 60 shared genes generated trees with the same topologies, and P. taeda was closely related to P. contorta in the subgenus Pinus. Thus, the complete P. taeda genome provided valuable resources for population and evolutionary studies of gymnosperms and can be used to identify related species. PMID- 29596417 TI - Eleven quick tips for running an interdisciplinary short course for new graduate students. AB - Quantitative reasoning and techniques are increasingly ubiquitous across the life sciences. However, new graduate researchers with a biology background are often not equipped with the skills that are required to utilize such techniques correctly and efficiently. In parallel, there are increasing numbers of engineers, mathematicians, and physical scientists interested in studying problems in biology with only basic knowledge of this field. Students from such varied backgrounds can struggle to engage proactively together to tackle problems in biology. There is therefore a need to establish bridges between those disciplines. It is our proposal that the beginning of graduate school is the appropriate time to initiate those bridges through an interdisciplinary short course. We have instigated an intensive 10-day course that brought together new graduate students in the life sciences from across departments within the National University of Singapore. The course aimed at introducing biological problems as well as some of the quantitative approaches commonly used when tackling those problems. We have run the course for three years with over 100 students attending. Building on this experience, we share 11 quick tips on how to run such an effective, interdisciplinary short course for new graduate students in the biosciences.

AB - Additive manufacturing has been a cornerstone of the product development pipeline for decades, playing an essential role in the creation of both functional and cosmetic prototypes. In recent years, the prospects for distributed and open source manufacturing have grown tremendously. This growth has been enabled by an expanding library of printable materials, low-cost printers, and communities dedicated to platform development. The microfluidics community has embraced this opportunity to integrate 3D printing into the suite of manufacturing strategies used to create novel fluidic architectures. The rapid turnaround time and low cost to implement these strategies in the lab makes 3D printing an attractive alternative to conventional micro- and nanofabrication techniques. In this work, the production of multiple microfluidic architectures using a hybrid 3D printing soft lithography approach is demonstrated and shown to enable rapid device fabrication with channel dimensions that take advantage of laminar flow characteristics. The fabrication process outlined here is underpinned by the implementation of custom design software with an integrated slicer program that replaces less intuitive computer aided design and slicer software tools. Devices are designed in the program by assembling parameterized microfluidic building blocks. The fabrication process and flow control within 3D printed devices were demonstrated with a gradient generator and two droplet generator designs. Precise control over the printing process allowed 3D microfluidics to be printed in a single step by extruding bridge structures to 'jump-over' channels in the same plane. This strategy was shown to integrate with conventional nanofabrication strategies to simplify the operation of a platform that incorporates both nanoscale features and 3D printed microfluidics.

PMID- 29596422 TI - Calculation for tensile strength and fracture toughness of granite with three kinds of grain sizes using three-point-bending test. AB - Tensile strength and fracture toughness, important parameters of the rock for engineering applications are difficult to measure. Thus this paper selected three kinds of granite samples (grain sizes = 1.01mm, 2.12mm and 3mm), used the combined experiments of physical and numerical simulation (RFPA-DIP version) to conduct three-point-bending (3-p-b) tests with different notches and introduced the acoustic emission monitor system to analyze the fracture mechanism around the notch tips. To study the effects of grain size on the tensile strength and toughness of rock samples, a modified fracture model was established linking fictitious crack to the grain size so that the microstructure of the specimens and fictitious crack growth can be considered together. The fractal method was introduced to represent microstructure of three kinds of granites and used to determine the length of fictitious crack. It is a simple and novel method to calculate the tensile strength and fracture toughness directly. Finally, the theoretical model was verified by the comparison to the numerical experiments by calculating the nominal strength sigman and maximum loads Pmax. PMID- 29596423 TI - SARNAclust: Semi-automatic detection of RNA protein binding motifs from immunoprecipitation data. AB - RNA-protein binding is critical to gene regulation, controlling fundamental processes including splicing, translation, localization and stability, and aberrant RNA-protein interactions are known to play a role in a wide variety of diseases. However, molecular understanding of RNA-protein interactions remains limited; in particular, identification of RNA motifs that bind proteins has long been challenging, especially when such motifs depend on both sequence and structure. Moreover, although RNA binding proteins (RBPs) often contain more than one binding domain, algorithms capable of identifying more than one binding motif simultaneously have not been developed. In this paper we present a novel pipeline to determine binding peaks in crosslinking immunoprecipitation (CLIP) data, to discover multiple possible RNA sequence/structure motifs among them, and to experimentally validate such motifs. At the core is a new semi-automatic algorithm SARNAclust, the first unsupervised method to identify and deconvolve multiple sequence/structure motifs simultaneously. SARNAclust computes similarity between sequence/structure objects using a graph kernel, providing the ability to isolate the impact of specific features through the bulge graph formalism. Application of SARNAclust to synthetic data shows its capability of clustering 5 motifs at once with a V-measure value of over 0.95, while GraphClust achieves only a V-measure of 0.083 and RNAcontext cannot detect any of the motifs. When applied to existing eCLIP sets, SARNAclust finds known motifs for SLBP and HNRNPC and novel motifs for several other RBPs such as AGGF1, AKAP8L and ILF3. We demonstrate an experimental validation protocol, a targeted Bind-n-Seq-like high throughput sequencing approach that relies on RNA inverse folding for oligo pool design, that can validate the components within the SLBP motif. Finally, we use this protocol to experimentally interrogate the SARNAclust motif predictions for protein ILF3. Our results support a newly identified partially double-stranded UUUUUGAGA motif similar to that known for the splicing factor HNRNPC. PMID- 29596424 TI - Germ cells in the teleost fish medaka have an inherent feminizing effect. AB - AUTHOR SUMMARY: Germ cells are the only cells that can transfer genetic materials to the next generation via the sperm or egg. However, recent analyses in teleosts revealed another essential role of germ cells: feminizing the gonads. In our study, medaka mutants in which gametogenesis was blocked at specific stages provides the novel view that the feminizing effect of germ cells occurs in parallel with other reproductive elements, such as meiosis, the sexual fate decision of germ cells, and gametogenesis. Germ cells in medaka may have a potential to feminize gonads at the moment they have developed. PMID- 29596425 TI - The 'COmorBidity in Relation to AIDS' (COBRA) cohort: Design, methods and participant characteristics. AB - BACKGROUND: Persons living with HIV on combination antiretroviral therapy (cART) may be at increased risk of the development of age-associated non-communicable comorbidities (AANCC) at relatively young age. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated aging. OBJECTIVE: The COmorBidity in Relation to AIDS (COBRA) cohort study was designed to investigate the potential causal link between HIV and AANCC, amongst others, in a cohort of middle-aged individuals with HIV with sustained viral suppression on cART and otherwise comparable HIV-negative controls. METHODS: Longitudinal cohort study of HIV-positive subjects >=45 years of age, with sustained HIV suppression on cART recruited from two large European HIV treatment centres and similarly-aged HIV-negative controls recruited from sexual health centres and targeted community groups. Both HIV-positive and HIV-negative subjects were assessed at study entry and again at follow-up after 2 years. RESULTS: Of the 134 HIV-positive individuals with a median (IQR) age of 56 (51, 62) years recruited, 93% were male, 88% of white ethnicity and 86% were men who have sex with men (MSM). Similarly, the 79 HIV-negative subjects had a median (IQR) age of 57 (52, 64) and 92% were male, 97% of white ethnicity and 80% were MSM. CONCLUSIONS: The results from the COBRA study will be a significant resource to understand the link between HIV and AANCC and the pathogenic mechanisms underlying this link. COBRA will inform future development of novel prognostic tools for earlier diagnosis of AANCC and of novel interventions which, as an adjunct to cART, may prevent AANCC. PMID- 29596426 TI - Quantifying the impact of scholarly papers based on higher-order weighted citations. AB - Quantifying the impact of a scholarly paper is of great significance, yet the effect of geographical distance of cited papers has not been explored. In this paper, we examine 30,596 papers published in Physical Review C, and identify the relationship between citations and geographical distances between author affiliations. Subsequently, a relative citation weight is applied to assess the impact of a scholarly paper. A higher-order weighted quantum PageRank algorithm is also developed to address the behavior of multiple step citation flow. Capturing the citation dynamics with higher-order dependencies reveals the actual impact of papers, including necessary self-citations that are sometimes excluded in prior studies. Quantum PageRank is utilized in this paper to help differentiating nodes whose PageRank values are identical.

AB - Nutrition is a key factor in host-pathogen defense. Malnutrition can increase both host susceptibility and severity of infection through a number of pathways, and infection itself can promote nutritional deterioration and further susceptibility. Nutritional status can also strongly influence response to vaccination or therapeutic pharmaceuticals. Arthropod-borne viruses (arboviruses) have a long history of infecting humans, resulting in regular pandemics as well as an increasing frequency of autochthonous transmission. Interestingly, aside from host-related factors, nutrition could also play a role in the competence of vectors required for transmission of these viruses. Nutritional status of the host and vector could even influence viral evolution itself. Therefore, it is vital to understand the role of nutrition in the arbovirus lifecycle. This Review will focus on nutritional factors that could influence susceptibility and severity of infection in the host, response to prophylactic and therapeutic strategies, vector competence, and viral evolution. PMID- 29596429 TI - Age-related collagen turnover of the interstitial matrix and basement membrane: Implications of age- and sex-dependent remodeling of the extracellular matrix. AB - The extracellular matrix (ECM) plays a vital role in maintaining normal tissue function. Collagens are major components of the ECM and there is a tight equilibrium between degradation and formation of these proteins ensuring tissue health and homeostasis. As a consequence of tissue turnover, small collagen fragments are released into the circulation, which act as important biomarkers in the study of certain tissue-related remodeling factors in health and disease. The aim of this study was to establish an age-related collagen turnover profile of the main collagens of the interstitial matrix (type I and III collagen) and basement membrane (type IV collagen) in healthy men and women. By using well characterized competitive ELISA-assays, we assessed specific fragments of degraded (C1M, C3M, C4M) and formed (PINP, Pro-C3, P4NP7S) type I, III and IV collagen in serum from 617 healthy men and women ranging in ages from 22 to 86. Subjects were divided into 5-year age groups according to their sex and age. Groups were compared using Kruskal-Wallis adjusted for Dunn's multiple comparisons test and Mann-Whitney t-test. Age-specific changes in collagen turnover was most profound for type I collagen. PINP levels decreased in men with advancing age, whereas in women, the level decreased in early adulthood followed by an increase around the age of menopause (age 40-60). Sex-specific changes in type I, III and IV collagen turnover was present at the age around menopause (age 40-60) with women having an increased turnover. In summary, collagen turnover is affected by age and sex with the interstitial matrix and the basement membrane being differently regulated. The observed changes needs to be accounted for when measuring ECM related biomarkers in clinical studies. PMID- 29596430 TI - Integrating data from multiple sources for insights into demographic processes: Simulation studies and proof of concept for hierarchical change-in-ratio models. AB - We developed a model for estimating demographic rates and population abundance based on multiple data sets revealing information about population age- and sex structure. Such models have previously been described in the literature as change in-ratio models, but we extend the applicability of the models by i) using time series data allowing the full temporal dynamics to be modelled, by ii) casting the model in an explicit hierarchical modelling framework, and by iii) estimating parameters based on Bayesian inference. Based on sensitivity analyses we conclude that the approach developed here is able to obtain estimates of demographic rate with high precision whenever unbiased data of population structure are available. Our simulations revealed that this was true also when data on population abundance are not available or not included in the modelling framework. Nevertheless, when data on population structure are biased due to different observability of different age- and sex categories this will affect estimates of all demographic rates. Estimates of population size is particularly sensitive to such biases, whereas demographic rates can be relatively precisely estimated even with biased observation data as long as the bias is not severe. We then use the models to estimate demographic rates and population abundance for two Norwegian reindeer (Rangifer tarandus) populations where age-sex data were available for all harvested animals, and where population structure surveys were carried out in early summer (after calving) and late fall (after hunting season), and population size is counted in winter. We found that demographic rates were similar regardless whether we include population count data in the modelling, but that the estimated population size is affected by this decision. This suggest that monitoring programs that focus on population age- and sex structure will benefit from collecting additional data that allow estimation of observability for different age- and sex classes. In addition, our sensitivity analysis suggests that focusing monitoring towards changes in demographic rates might be more feasible than monitoring abundance in many situations where data on population age- and sex structure can be collected. PMID- 29596431 TI - Measuring the preparedness of health facilities to deliver emergency obstetric care in a South African district. AB - BACKGROUND: Improving the delivery of emergency obstetric care (EmNOC) remains critical in addressing direct causes of maternal mortality. United Nations (UN) agencies have promoted standard methods for evaluating the availability of EmNOC facilities although modifications have been proposed by others. This study presents an assessment of the preparedness of public health facilities to provide EmNOC using these methods in one South African district with a persistently high maternal mortality ratio. METHODS: Data collection took place in the final quarter of 2014. Cross-sectional surveys were conducted to classify the 7 hospitals and 8 community health centres (CHCs) in the district as either basic EmNOC (BEmNOC) or comprehensive EmNOC (CEmNOC) facilities using UN EmNOC signal functions. The required density of EmNOC facilities was calculated using UN norms. We also assessed the availability of EmNOC personnel, resuscitation equipment, drugs, fluids, and protocols at each facility. The workload of skilled EmNOC providers at hospitals and CHCs was compared. RESULTS: All 7 hospitals in the district were classified as CEmNOC facilities, but none of the 8 CHCs performed all required signal functions to be classified as BEmNOC facilities. UN norms indicated that 25 EmNOC facilities were required for the district population, 5 of which should be CEmNOCs. None of the facilities had 100% of items on the EmNOC checklists. Hospital midwives delivered an average of 36.4+/ 14.3 deliveries each per month compared to only 7.9+/-3.2 for CHC midwives (p<0.001). CONCLUSIONS: The analysis indicated a shortfall of EmNOC facilities in the district. Full EmNOC services were centralised to hospitals to assure patient safety even though national policy guidelines sanction more decentralisation to CHCs. Studies measuring EmNOC availability need to consider facility opening hours, capacity and staffing in addition to the demonstrated performance of signal functions. PMID- 29596432 TI - Bold personality makes domestic dogs entering a shelter less vulnerable to diseases. AB - It is widely recognised that for vertebrate species, personalities vary along an axis with extremes represented by 'proactive' and 'reactive' individuals. The aim of this study was to verify whether there is a relationship between personality and disease vulnerability in domestic dogs (Canis familiaris) exposed to an intensely stressful situation such as entering a shelter. Twenty-eight shelter dogs participated in the study. The ethogram consisted of approximately 100 behavioural patterns. Behavioural observations of dogs in their new environment, a Novel Object and a T-maze test were used to evaluate the personality of the dogs captured as strays and entering the shelter. A blood sample from each dog was obtained at admission into the shelter and after a month to evaluate their immunological state. Based on PCA analyses of observational combined with experimental data, the dogs were ordered along the boldness-shyness axis, with the first being the boldest. Excluding one (the 6th), the first 10 dogs showed an improved health status: absence of disease symptoms during the 30 days of monitoring and improved immunological parameters; the opposite was found for shy dogs. The results of this research seem to confirm findings in other vertebrate species, i.e., bold and shy dog vulnerability to diseases might be different, especially when they must cope with a stressful and highly infectious environment such as a dog shelter. PMID- 29596433 TI - The benzodiazepine-like natural product tilivalline is produced by the entomopathogenic bacterium Xenorhabdus eapokensis. AB - The pyrrolobenzodiazepine tilivalline (1) was originally identified in the human gut pathobiont Klebsiella oxytoca, the causative agent of antibiotic-associated hemorrhagic colitis. Here we show the identification of tilivalline and analogs thereof in the entomopathogenic bacterium Xenorhabdus eapokensis as well as the identification of its biosynthesis gene cluster encoding a bimodular non ribosomal peptide synthetase. Heterologous expression of both genes in E. coli resulted in the production of 1 and from mutasynthesis and precursor directed biosynthesis 11 new tilivalline analogs were identified in X. eapokensis. These results allowed the prediction of the tilivalline biosynthesis being similar to that in K. oxytoca.

AB - BACKGROUND: The Union in collaboration with national TB programme (NTP) started the community-based MDR-TB care (CBMDR-TBC) project in 33 townships of upper Myanmar to improve treatment initiation and treatment adherence. Patients with MDR-TB diagnosed/registered under NTP received support through the project staff, in addition to the routine domiciliary care provided by NTP staff. Each township had a project nurse exclusively for MDR-TB and 30 USD per month (max. for 4 months) were provided to the patient as a pre-treatment support. OBJECTIVES: To assess whether CBMDR-TBC project's support improved treatment initiation. METHODS: In this cohort study (involving record review) of all diagnosed MDR-TB between January 2015 and June 2016 in project townships, CBMDR-TBC status was categorized as "receiving support" if date of project initiation in patient's township was before the date of diagnosis and "not receiving support", if otherwise. Cox proportional hazards regression (censored on 31 Dec 2016) was done to identify predictors of treatment initiation. RESULTS: Of 456 patients, 57% initiated treatment: 64% and 56% among patients "receiving support (n = 208)" and "not receiving support (n = 228)" respectively (CBMDR-TBC status was not known in 20 (4%) patients due to missing diagnosis dates). Among those initiated on treatment (n = 261), median (IQR) time to initiate treatment was 38 (20, 76) days: 31 (18, 50) among patients "receiving support" and 50 (26,101) among patients "not receiving support". After adjusting other potential confounders (age, sex, region, HIV, past history of TB treatment), patients "receiving support" had 80% higher chance of initiating treatment [aHR (0.95 CI): 1.8 (1.3, 2.3)] when compared to patients "not receiving support". In addition, age 15-54 years, previous history of TB and being HIV negative were independent predictors of treatment initiation. CONCLUSION: Receiving support under CBMDR-TBC project improved treatment initiation: it not only improved the proportion initiated but also reduced time to treatment initiation. We also recommend improved tracking of all diagnosed patients as early as possible. PMID- 29596436 TI - Differences between nitrogen-tolerant and nitrogen-susceptible sweetpotato cultivars in photosynthate distribution and transport under different nitrogen conditions. AB - To characterize the differences in photosynthate distribution and transport between nitrogen(N)-tolerant and N-susceptible sweetpotato cultivars under different N conditions, three N levels, including 0 (N0), 120 (N120), and 240 kg ha-1 (N240), were used in field experiments with the Jishu26 (J26) and Xushu32 (X32) cultivars in 2015 and 2016. The results from both years revealed that high N application reduced the tuberous root yield, the tuber/vine rate of carbon-13 (13C), and top-to-base (three equal segments of stem divided from the fifth opened leaf of the shoot tip to the main stem, defined as the top, middle, and base parts, respectively) gradients such as sucrose, ammonia N and potassium along the stem. 'J26' showed a higher yield than 'X32' under N0 but lower yield than 'X32' under N120 and N240. It also exhibited a higher 13C distribution to tuberous roots compared with that of 'X32' under N0, and the opposite trend was observed under N120 and N240. Under N0, 'J26' showed a steep top-to-base amino acid gradient and a significantly lower top-to-base sucrose increase along the stem in the late growth stage. Under N120 and N240, 'X32' exhibited a greater top to-base decrease in the ammonia N along the stem during the main growth stages, a steep top-to-base sucrose gradient along the stem in the early growth stage, and a lower top-to-base sucrose increase along the stem in the middle and late growth stages. The formation of a reasonable photosynthate distribution structure attributed to high yield was related to a desirable sucrose, ammonia N or K+ gradient downward along the stem. These results might help provide farmers with sweetpotato cultivars using less or no N fertilizer in soils of different fertility and enhance the knowledge of yield-related physiology. PMID- 29596435 TI - Integrated analysis of tumor differentiation genes in pancreatic adenocarcinoma. AB - BACKGROUND: Tumor differentiation is an important process in the development of cancer. It is valuable to identify key differentiation related genes in the prognosis and therapy of pancreatic adenocarcinoma. METHODS: The mRNA expression data were downloaded from the Cancer Genome Atlas database. Then, differentially expressed tumor differentiation related genes were identified. Additionally, Gene Ontology functional categories and Kyoto Encyclopedia of Genes and Genomes biochemical pathway was used to explore the function. In addition, receiver operating characteristic and survival analysis were carried out to assess the diagnosis and prognosis value. Finally, the electronic validation of selected tumor differentiation related genes was performed. RESULTS: A total of 932 genes were identified. Among which, 8 genes including JUB, ERLIN1, HMGA2, FAM110B, EGFR, MCM2, TCTA and SSTR1 were differentially expressed in all different tumor differentiation grades. Functional analysis revealed those genes between highly differentiated and other differentiation were remarkably enriched in pancreatic adenocarcinoma and cell cycle pathway. Finally, ERLIN1, HMGA2, FAM110B, EGFR, MCM2, BCL2L1, E2F1 and RAC1 were associated with the survival time of pancreatic adenocarcinoma patient. Among these genes, JUB, ERLIN1, FAM110B, MCM2 and BCL2L1 also had a diagnosis value for pancreatic adenocarcinoma. Additionally, the expression trend of JUB, HMGA2 and MCM2 was increased along with the tumor differentiation grades. And the expression trend of FAM110B was decreased along with the tumor differentiation grades. The electronic validation result was consistent with the bioinformatics analysis. CONCLUSIONS: 12 tumor differentiation related genes including JUB, ERLIN1, HMGA2, FAM110B, EGFR, MCM2, TCTA, SSTR1, BCL2L1, E2F1, RAC1 and STAT1 played crucial roles in the differentiation of pancreatic adenocarcinoma. PMID- 29596437 TI - Are the unken reflex and the aposematic colouration of Red-Bellied Toads efficient against bird predation? AB - Aposematic signals as well as body behaviours may be important anti-predator defences. Species of the genus Melanophryniscus are characterised by having toxic lipophilic alkaloids in the skin and for presenting a red ventral colouration, which can be observed when they perform the behaviour called the unken reflex. Both the reflex behaviour and the colouration pattern are described as defence mechanisms. However, there are currently no studies testing their effectiveness against predators. This study aimed to test experimentally if both ventral conspicuous colouration and the unken reflex in Melanophryniscus cambaraensis function as aposematic signals against visually oriented predators (birds). We simulated the species studied using three different clay toad models as follows: (a) in a normal position with green coloured bodies, (b) in the unken reflex position with green coloured body and extremities and (c) in the unken reflex position with a green body and red extremities. Models were distributed on a known M. cambaraensis breeding site and in the adjacent forest. More than half of the attacks on the models were from birds; however, there was no preference for any model type. Thus, just the presence of the red colour associated with the motionless unken reflex position does not seem to prevent attacks from potential predators. It is possible that the effective aposematic signal in Melanophryniscus is achieved through the unken reflex movement together with the subsequent exhibition of the warning colouration and the secretion of toxins. PMID- 29596438 TI - Predation risk landscape modifies flying and red squirrel nest site occupancy independently of habitat amount. AB - Habitat choice often entails trade-offs between food availability and predation risk. Understanding the distribution of individuals in space thus requires that both habitat characteristics and predation risk are considered simultaneously. Here, we studied the nest box use of two arboreal squirrels who share preferred habitat with their main predators. Nocturnal Ural owls (Strix uralensis) decreased occurrence of night-active flying squirrels (Pteromys volans) and diurnal goshawks (Accipiter gentilis) that of day-active red squirrels (Sciurus vulgaris). Unexpectedly, the amount of preferred habitat had no effect on nest box use, but, surprisingly, both squirrel species seemed to benefit from close proximity to agricultural fields and red squirrels to urban areas. We found no evidence of trade-off between settling in a high-quality habitat and avoiding predators. However, the amount of poor-quality young pine forests was lower in occupied sites where goshawks were present, possibly indicating habitat specific predation on red squirrels. The results suggest that erecting nest boxes for Ural owls should be avoided in the vicinity of flying squirrel territories in order to conserve the near threatened flying squirrels. Our results also suggest that flying squirrels do not always need continuous old forests, and hence the currently insufficient conservation practices could be improved with reasonable increases in the areas left untouched around their nests. The results of this study demonstrate the importance of taking into account both habitat requirements and predation risk as well as their interactive effects when modeling the occupancy of threatened animal species and planning their conservation. PMID- 29596439 TI - Expression of progenitor markers is associated with the functionality of a bioartificial adrenal cortex. AB - Encapsulation of primary bovine adrenocortical cells in alginate is an efficacious model of a bioartificial adrenal cortex. Such a bioartificial adrenal cortex can be used for the restoration of lost adrenal function in vivo as well as for in vitro modeling of the adrenal microenvironment and for investigation of cell-cell interactions in the adrenals. The aim of this work was the optimization of a bioartificial adrenal cortex, that is the generation of a highly productive, self-regenerating, long-term functioning and immune tolerant bioartificial organ. To achieve this, it is necessary that adrenocortical stem and progenitor cells are present in the bioartificial gland, as these undifferentiated cells play important roles in the function of the mature gland. Here, we verified the presence of adrenocortical progenitors in cultures of bovine adrenocortical cells, studied the dynamics of their appearance and growth and determined the optimal time point for cell encapsulation. These procedures increased the functional life span and reduced the immunogenicity of the bioartificial adrenal cortex. This model allows the use of the luteinizing hormone-releasing hormone (LHRH) agonist triptorelin, the neuropeptide bombesin, and retinoic acid to alter cell number and the release of cortisol over long periods of time. PMID- 29596441 TI - Quantifying donor-to-donor variation in macrophage responses to the human fungal pathogen Cryptococcus neoformans. AB - Cryptococcosis remains the leading cause of fungal meningitis worldwide, caused primarily by the pathogen Cryptococcus neoformans. Symptomatic cryptococcal infections typically affect immunocompromised patients. However, environmental exposure to cryptococcal spores is ubiquitous and most healthy individuals are thought to harbor infections from early childhood onwards that are either resolved, or become latent. Since macrophages are a key host cell for cryptococcal infection, we sought to quantify the extent of individual variation in this early phagocyte response within a small cohort of healthy volunteers with no reported immunocompromising conditions. We show that rates of both intracellular fungal proliferation and non-lytic expulsion (vomocytosis) are remarkably variable between individuals. However, we demonstrate that neither gender, in vitro host inflammatory cytokine profiles, nor polymorphisms in several key immune genes are responsible for this variation. Thus the data we present serve to quantify the natural variation in macrophage responses to this important human pathogen and will hopefully provide a useful "benchmark" for the research community. PMID- 29596440 TI - Effectiveness of school food environment policies on children's dietary behaviors: A systematic review and meta-analysis. AB - BACKGROUND: School food environment policies may be a critical tool to promote healthy diets in children, yet their effectiveness remains unclear. OBJECTIVE: To systematically review and quantify the impact of school food environment policies on dietary habits, adiposity, and metabolic risk in children. METHODS: We systematically searched online databases for randomized or quasi-experimental interventions assessing effects of school food environment policies on children's dietary habits, adiposity, or metabolic risk factors. Data were extracted independently and in duplicate, and pooled using inverse-variance random-effects meta-analysis. Habitual (within+outside school) dietary intakes were the primary outcome. Heterogeneity was explored using meta-regression and subgroup analysis. Funnel plots, Begg's and Egger's test evaluated potential publication bias. RESULTS: From 6,636 abstracts, 91 interventions (55 in US/Canada, 36 in Europe/New Zealand) were included, on direct provision of healthful foods/beverages (N = 39 studies), competitive food/beverage standards (N = 29), and school meal standards (N = 39) (some interventions assessed multiple policies). Direct provision policies, which largely targeted fruits and vegetables, increased consumption of fruits by 0.27 servings/d (n = 15 estimates (95%CI: 0.17, 0.36)) and combined fruits and vegetables by 0.28 servings/d (n = 16 (0.17, 0.40)); with a slight impact on vegetables (n = 11; 0.04 (0.01, 0.08)), and no effects on total calories (n = 6; -56 kcal/d (-174, 62)). In interventions targeting water, habitual intake was unchanged (n = 3; 0.33 glasses/d (-0.27, 0.93)). Competitive food/beverage standards reduced sugar-sweetened beverage intake by 0.18 servings/d (n = 3 (-0.31, -0.05)); and unhealthy snacks by 0.17 servings/d (n = 2 (-0.22, -0.13)), without effects on total calories (n = 5; -79 kcal/d (-179, 21)). School meal standards (mainly lunch) increased fruit intake (n = 2; 0.76 servings/d (0.37, 1.16)) and reduced total fat (-1.49%energy; n = 6 (-2.42, -0.57)), saturated fat (n = 4; -0.93%energy (-1.15, -0.70)) and sodium (n = 4; -170 mg/d (-242, -98)); but not total calories (n = 8; -38 kcal/d (-137, 62)). In 17 studies evaluating adiposity, significant decreases were generally not identified; few studies assessed metabolic factors (blood lipids/glucose/pressure), with mixed findings. Significant sources of heterogeneity or publication bias were not identified. CONCLUSIONS: Specific school food environment policies can improve targeted dietary behaviors; effects on adiposity and metabolic risk require further investigation. These findings inform ongoing policy discussions and debates on best practices to improve childhood dietary habits and health. PMID- 29596442 TI - Association of adverse childhood experiences and health risk behaviors among young adults visiting a regional primary healthcare center, Federation of Bosnia and Herzegovina. AB - BACKGROUND: Many studies have linked adverse childhood experiences (ACEs) to long term health outcomes, as well as health risk behaviors. In the post-war period in Bosnia and Herzegovina, many young people grew up in an environment of deteriorated living standards due to high unemployment and economic insecurity. The objectives of the study were to: 1) describe the health risk behaviors of young adults accessing primary healthcare; and 2) examine associations of these risk factors with adverse childhood experiences in this context. METHODS: This was a cross-sectional survey, conducted from April to October 2014. Participants were recruited from the Primary Healthcare Center Zenica. Patients between the ages of 18 and 24 were eligible for inclusion. The informed consent and self administered questionnaire were offered to patients during clinic intake. The questionnaire contained questions on sexual and reproductive health, use of alcohol and drugs, dating violence, and adverse childhood experiences. RESULTS: During the study period 520 questionnaires were distributed, and 400 complete surveys were returned, for a response rate of 76.9%. Among the 400 respondents, 166 were males (41.5%) and 234 were females (58.5%). Our study showed that 48.7% of respondents had experienced some form of childhood adversity. Emotional neglect was the most common type of adverse childhood experience (25.6%) and was significantly more prevalent among females. Our study indicated that more than 15% of respondents had witnessed domestic violence. Overall, ACEs were associated with increased odds of early sex initiation, alcohol use, drug use, and dating violence, although some of these associations did not reach statistical significance. Emotional neglect was the exception, and reporting emotional neglect was associated with a significantly elevated odds ratio for all four of the health risk behaviors. Emotional abuse was associated with an increased odds of drug abuse (OR = 2.78; 95% CI = 1.31-5.90) and dating violence (OR = 2.31; 95% CI = 1.10-4.89). Sexual abuse was marginally associated with increased early sex initiation (OR = 3.2; 95% CI 0.93-10.8). Parental divorce was significantly associated with alcohol abuse. CONCLUSION: The results of this study demonstrated associations between adverse experiences in childhood and the probability of engaging in health risk behavior which has implications for health outcomes in the long-term. PMID- 29596443 TI - Serum anti-glycan-antibodies in relatives of patients with inflammatory bowel disease. AB - BACKGROUND: Serum anti-glycan antibodies are a promising tool for differential diagnosis, disease stratification and prediction of Crohn's disease (CD). To investigate possible heritability of the markers we assessed the presence of serum anti-glycan antibodies in affected and unaffected relatives of patients with CD. METHODS: Serum samples of 169 IBD patients of the German inflammatory bowel disease (IBD) network (140 CD & 29 Ulcerative colitis (UC)), 349 relatives of CD patients, 63 relatives of UC patients and 46 healthy controls were tested for the presence of anti-glycan antibodies by ELISA in a blinded fashion. Clinical data of the IBD patients and controls were available. RESULTS: A higher proportion of non-affected CD relatives was positive for anti-glycan antibodies compared to healthy subjects. No inheritance of a specific pattern of anti-glycan antibodies could be detected. No difference in marker expression depending on the degree of relationship in the non-affected relatives was noted and the presence of family history did not lead to a difference in marker levels in the affected CD subjects. CONCLUSIONS: Non-affected CD relatives had a higher frequency of anti-glycan antibodies compared to healthy subjects. This difference was mild and was found to be true for the overall reactivity to glycan antigens, but not for specific patterns. This may indicate an inherited mechanism resulting in a non specific increased reactivity to microbial antigens in IBD. PMID- 29596444 TI - Incidence and case fatality rates of community-acquired pneumonia and pneumococcal diseases among Korean adults: Catchment population-based analysis. AB - BACKGROUND: Pneumonia is a leading infectious cause of morbidity and mortality among adults. Pneumococcal pneumonia (PP) is the most common vaccine-preventable bacterial etiology of pneumonia. In this study, we estimated the incidence of community-acquired pneumonia (CAP) and pneumococcal diseases among Korean adults. METHODS: Clinical and microbiological databases from three hospitals were retrospectively reviewed to determine the incidence and case fatality rates of CAP and pneumococcal diseases in Korean adults aged >=19 years from 2011 to 2014. Incidence and case fatality rates of CAP, PP and invasive pneumococcal diseases (IPD) were evaluated based on the catchment population. Catchment population was calculated using national health insurance data, estimating the proportion of patients with pneumonia that were medically attended at each hospital. RESULTS: Among 5,783 patients with medically attended CAP, 833 (14.4%) had PP. For IPD, a total of 91 culture-confirmed cases were identified. The overall incidence of CAP was 307.7 cases per 100,000 persons per year with an in-hospital mortality rate of 6.2%. The estimated annual incidence of pneumococcal pneumonia was 42.2-49.4 cases per 100,000 persons per year, increasing with age to >280 per 100,000 persons per year in older patients over 70 years. The annual incidence of IPD had a range of 4.1-6.5 cases per 100,000 persons per year. The overall case fatality rate for invasive pneumococcal diseases was 30.8% with the highest rate of 66.7% in patients over 80 years. CONCLUSION: Over the study period, incidences of CAP, PP and IPD were consistently high, particularly in older people. These results provide baseline data to establish healthcare strategies and estimate their impact among Korean adults. PMID- 29596445 TI - Time spent with cats is never wasted: Lessons learned from feline acromegalic cardiomyopathy, a naturally occurring animal model of the human disease. AB - BACKGROUND: In humans, acromegaly due to a pituitary somatotrophic adenoma is a recognized cause of increased left ventricular (LV) mass. Acromegalic cardiomyopathy is incompletely understood, and represents a major cause of morbidity and mortality. We describe the clinical, echocardiographic and histopathologic features of naturally occurring feline acromegalic cardiomyopathy, an emerging disease among domestic cats. METHODS: Cats with confirmed hypersomatotropism (IGF-1>1000ng/ml and pituitary mass; n = 67) were prospectively recruited, as were two control groups: diabetics (IGF-1<800ng/ml; n = 24) and healthy cats without known endocrinopathy or cardiovascular disease (n = 16). Echocardiography was performed in all cases, including after hypersomatotropism treatment where applicable. Additionally, tissue samples from deceased cats with hypersomatotropism, hypertrophic cardiomyopathy and age matched controls (n = 21 each) were collected and systematically histopathologically reviewed and compared. RESULTS: By echocardiography, cats with hypersomatotropism had a greater maximum LV wall thickness (6.5mm, 4.1 10.1mm) than diabetic (5.9mm, 4.2-9.1mm; Mann Whitney, p<0.001) or control cats (5.2mm, 4.1-6.5mm; Mann Whitney, p<0.001). Left atrial diameter was also greater in cats with hypersomatotropism (16.6mm, 13.0-29.5mm) than in diabetic (15.4mm, 11.2-20.3mm; Mann Whitney, p<0.001) and control cats (14.0mm, 12.6-17.4mm; Mann Whitney, p<0.001). After hypophysectomy and normalization of IGF-1 concentration (n = 20), echocardiographic changes proved mostly reversible. As in humans, histopathology of the feline acromegalic heart was dominated by myocyte hypertrophy with interstitial fibrosis and minimal myofiber disarray. CONCLUSIONS: These results demonstrate cats could be considered a naturally occurring model of acromegalic cardiomyopathy, and as such help elucidate mechanisms driving cardiovascular remodeling in this disease. PMID- 29596446 TI - Gut microbiota varies by opioid use, circulating leptin and oxytocin in African American men with diabetes and high burden of chronic disease. AB - OBJECTIVE: The gut microbiota is known to be related to type 2 diabetes (T2D), psychiatric conditions, and opioid use. In this study, we tested the hypothesis that variability in gut microbiota in T2D is associated with psycho-metabolic health. METHODS: A cross-sectional study was conducted among African American men (AAM) (n = 99) that were outpatients at a Chicago VA Medical Center. The main outcome measures included fecal microbiota ecology (by 16S rRNA gene sequencing), psychiatric disorders including opioid use, and circulating leptin and oxytocin as representative hormone biomarkers for obesity and psychological pro-social behavior. RESULTS: The study subjects had prevalent overweight/obesity (78%), T2D (50%) and co-morbid psychiatric (65%) and opioid use (45%) disorders. In the analysis of microbiota, the data showed interactions of opioids, T2D and metformin with Bifidobacterium and Prevotella genera. The differential analysis of Bifidobacterium stratified by opioids, T2D and metformin, showed significant interactions among these factors indicating that the effect of one factor was changed by the other (FDR-adjusted p [q] < 0.01). In addition, the pair-wise comparison showed that participants with T2D not taking metformin had a significant 6.74 log2 fold increase in Bifidobacterium in opioid users as compared to non-users (q = 2.2 x 10-8). Since metformin was not included in this pair-wise comparison, the significant 'q' suggested association of opioid use with Bifidobacterium abundance. The differences in Bifidobacterium abundance could possibly be explained by opioids acting as organic cation transporter 1 (OCT1) inhibitors. Analysis stratified by lower and higher leptin and oxytocin (divided by the 50th percentile) in the subgroup without T2D showed lower Dialister in High-Leptin vs. Low-Leptin (p = 0.03). Contrary, the opposite was shown for oxytocin, higher Dialister in High-Oxytocin vs. Low-Oxytocin (p = 0.04). CONCLUSIONS: The study demonstrated for the first time that Bifidobacterium and Prevotella abundance was affected by interactions of T2D, metformin and opioid use. Also, in subjects without T2D Dialister abundance varied according to circulating leptin and oxytocin. PMID- 29596448 TI - Solution of magnetohydrodynamic flow and heat transfer of radiative viscoelastic fluid with temperature dependent viscosity in wire coating analysis. AB - Wire coating process is a continuous extrusion process for primary insulation of conducting wires with molten polymers for mechanical strength and protection in aggressive environments. In the present study, radiative melt polymer satisfying third grade fluid model is used for wire coating process. The effect of magnetic parameter, thermal radiation parameter and temperature dependent viscosity on wire coating analysis has been investigated. Reynolds model and Vogel's models have been incorporated for variable viscosity. The governing equations characterizing the flow and heat transfer phenomena are solved analytically by utilizing homotopy analysis method (HAM). The computed results are also verified by ND-Solve method (Numerical technique) and Adomian Decomposition Method (ADM). The effect of pertinent parameters is shown graphically. In addition, the instability of the flow in the flows of the wall of the extrusion die is well marked in the case of the Vogel model as pointed by Nhan-Phan-Thien. PMID- 29596447 TI - Citrus aurantium L. dry extracts promote C/ebpbeta expression and improve adipocyte differentiation in 3T3-L1 cells. AB - Metabolic and/or endocrine dysfunction of the white adipose tissue (WAT) contribute to the development of metabolic disorders, such as Type 2 Diabetes (T2D). Therefore, the identification of products able to improve adipose tissue function represents a valuable strategy for the prevention and/or treatment of T2D. In the current study, we investigated the potential effects of dry extracts obtained from Citrus aurantium L. fruit juice (CAde) on the regulation of 3T3-L1 cells adipocyte differentiation and function in vitro. We found that CAde enhances terminal adipocyte differentiation of 3T3-L1 cells raising the expression of CCAAT/enhancer binding protein beta (C/Ebpbeta), peroxisome proliferator activated receptor gamma (Ppargamma), glucose transporter type 4 (Glut4) and fatty acid binding protein 4 (Fabp4). CAde improves insulin-induced glucose uptake of 3T3-L1 adipocytes, as well. A focused analysis of the phases occurring in the pre-adipocytes differentiation to mature adipocytes furthermore revealed that CAde promotes the early differentiation stage by up-regulating C/ebpbeta expression at 2, 4 and 8 h post the adipogenic induction and anticipating the 3T3-L1 cell cycle entry and progression during mitotic clonal expansion (MCE). These findings provide evidence that the exposure to CAde enhances in vitro fat cell differentiation of pre-adipocytes and functional capacity of mature adipocytes, and pave the way to the development of products derived from Citrus aurantium L. fruit juice, which may improve WAT functional capacity and may be effective for the prevention and/or treatment of T2D. PMID- 29596449 TI - Sequence analysis of the potato aphid Macrosiphum euphorbiae transcriptome identified two new viruses. AB - The potato aphid, Macrosiphum euphorbiae, is an important agricultural pest that causes economic losses to potato and tomato production. To establish the transcriptome for this aphid, RNA-Seq libraries constructed from aphids maintained on tomato plants were used in Illumina sequencing generating 52.6 million 75-105 bp paired-end reads. The reads were assembled using Velvet/Oases software with SEED preprocessing resulting in 22,137 contigs with an N50 value of 2,003bp. After removal of contigs from tomato host origin, 20,254 contigs were annotated using BLASTx searches against the non-redundant protein database from the National Center for Biotechnology Information (NCBI) as well as IntereProScan. This identified matches for 74% of the potato aphid contigs. The highest ranking hits for over 12,700 contigs were against the related pea aphid, Acyrthosiphon pisum. Gene Ontology (GO) was used to classify the identified M. euphorbiae contigs into biological process, cellular component and molecular function. Among the contigs, sequences of microbial origin were identified. Sixty five contigs were from the aphid bacterial obligate endosymbiont Buchnera aphidicola origin and two contigs had amino acid similarities to viruses. The latter two were named Macrosiphum euphorbiae virus 2 (MeV-2) and Macrosiphum euphorbiae virus 3 (MeV-3). The highest sequence identity to MeV-2 had the Dysaphis plantaginea densovirus, while to MeV-3 is the Hubei sobemo-like virus 49. Characterization of MeV-2 and MeV-3 indicated that both are transmitted vertically from adult aphids to nymphs. MeV-2 peptides were detected in the aphid saliva and only MeV-2 and not MeV-3 nucleic acids were detected inside tomato leaves exposed to virus-infected aphids. However, MeV-2 nucleic acids did not persist in tomato leaf tissues, after clearing the plants from aphids, indicating that MeV-2 is likely an aphid virus. PMID- 29596450 TI - Manual muscle testing and hand-held dynamometry in people with inflammatory myopathy: An intra- and interrater reliability and validity study. AB - Manual muscle testing (MMT) and hand-held dynamometry (HHD) are commonly used in people with inflammatory myopathy (IM), but their clinimetric properties have not yet been sufficiently studied. To evaluate the reliability and validity of MMT and HHD, maximum isometric strength was measured in eight muscle groups across three measurement events. To evaluate reliability of HHD, intra-class correlation coefficients (ICC), the standard error of measurements (SEM) and smallest detectable changes (SDC) were calculated. To measure reliability of MMT linear Cohen's Kappa was computed for single muscle groups and ICC for total score. Additionally, correlations between MMT8 and HHD were evaluated with Spearman Correlation Coefficients. Fifty people with myositis (56+/-14 years, 76% female) were included in the study. Intra-and interrater reliability of HHD yielded excellent ICCs (0.75-0.97) for all muscle groups, except for interrater reliability of ankle extension (0.61). The corresponding SEMs% ranged from 8 to 28% and the SDCs% from 23 to 65%. MMT8 total score revealed excellent intra-and interrater reliability (ICC>0.9). Intrarater reliability of single muscle groups was substantial for shoulder and hip abduction, elbow and neck flexion, and hip extension (0.64-0.69); moderate for wrist (0.53) and knee extension (0.49) and fair for ankle extension (0.35). Interrater reliability was moderate for neck flexion (0.54) and hip abduction (0.44); fair for shoulder abduction, elbow flexion, wrist and ankle extension (0.20-0.33); and slight for knee extension (0.08). Correlations between the two tests were low for wrist, knee, ankle, and hip extension; moderate for elbow flexion, neck flexion and hip abduction; and good for shoulder abduction. In conclusion, the MMT8 total score is a reliable assessment to consider general muscle weakness in people with myositis but not for single muscle groups. In contrast, our results confirm that HHD can be recommended to evaluate strength of single muscle groups. PMID- 29596451 TI - Exogenous application of the plant signalers methyl jasmonate and salicylic acid induces changes in volatile emissions from citrus foliage and influences the aggregation behavior of Asian citrus psyllid (Diaphorina citri), vector of Huanglongbing. AB - Huanglongbing, also known as citrus greening, is a destructive disease that threatens citrus production worldwide. It is putatively caused by the phloem limited bacterium Candidatus Liberibacter asiaticus (Las). Currently, the disease is untreatable and efforts focus on intensive insecticide use to control the vector, Asian citrus psyllid (Diaphorina citri). Emerging psyllid resistance to multiple insecticides has generated investigations into the use of exogenously applied signaling compounds to enhance citrus resistance to D. citri and Las. In the present study, we examined whether foliar applications of methyl jasmonate (MJ), a volatile signaling compound associated with the induced systemic resistance pathway, and salicylic acid, a constituent of the systemic acquired resistance pathway, would elicit the emission of defense-related volatiles in citrus foliage, and what effect this might have on the host-plant searching behavior of D. citri. Comparisons were made of volatiles emitted from growing shoots of uninfected and Las-infected 'Valencia' sweet orange (Citrus sinensis) trees over two consecutive sampling days. A settling behavioral assay was used to compare psyllid attraction to MJ-treated vs. Tween-treated citrus sprigs. All three main effects, Las infection status, plant signaler application, and sampling day, influenced the proportions of individual volatile compounds emitted in different treatment groups. MJ- and SA-treated trees had higher emission rates than Tween-treated trees. Methyl salicylate (MeSA) and beta-caryophyllene were present in higher proportions in the volatiles collected from Las-infected + trees. On the other hand, Las-infected + MJ-treated trees emitted lower proportions of MeSA than did Las-infected + Tween-treated trees. Because MeSA is a key D. citri attractant, this result suggests that MJ application could suppress MeSA emission from Las-infected trees, an approach that could be used to discourage psyllid colonization during shoot growth. MJ application enhanced emission of E-beta-ocimene, indole, volatiles attractive to many of the psyllid's natural enemies, indicating that MJ application could be used in an 'attract and reward' conservation biological control strategy. Volatile emissions in SA treated trees were dominated by MeSA. MJ application elicited aggregation behavior in D. citri. Similar numbers of psyllids settled on MJ-treated versus Tween-treated sprigs, but a significantly greater percentage of the MJ-treated sprigs had aggregations of nine or more psyllids on them. Taken together, the results of this study indicate that exogenous applications of MJ or SA could be used to influence Asian citrus psyllid settling behavior and attract its natural enemies. PMID- 29596452 TI - Anaerobic metabolism induces greater total energy expenditure during exercise with blood flow restriction. AB - PURPOSE: We investigated the energy system contributions and total energy expenditure during low intensity endurance exercise associated with blood flow restriction (LIE-BFR) and without blood flow restriction (LIE). METHODS: Twelve males participated in a contra-balanced, cross-over design in which subjects completed a bout of low-intensity endurance exercise (30min cycling at 40% of [Formula: see text]) with or without BFR, separated by at least 72 hours of recovery. Blood lactate accumulation and oxygen uptake during and after exercise were used to estimate the anaerobic lactic metabolism, aerobic metabolism, and anaerobic alactic metabolism contributions, respectively. RESULTS: There were significant increases in the anaerobic lactic metabolism (P = 0.008), aerobic metabolism (P = 0.020), and total energy expenditure (P = 0.008) in the LIE-BFR. No significant differences between conditions for the anaerobic alactic metabolism were found (P = 0.582). Plasma lactate concentration was significantly higher in the LIE-BFR at 15min and peak post-exercise (all P<=0.008). Heart rate was significantly higher in the LIE-BFR at 10, 15, 20, 25, and 30min during exercise, and 5, 10, and 15min after exercise (all P<=0.03). Ventilation was significantly higher in the LIE-BFR at 10, 15, and 20min during exercise (all P<=0.003). CONCLUSION: Low-intensity endurance exercise performed with blood flow restriction increases the anaerobic lactic and aerobic metabolisms, total energy expenditure, and cardiorespiratory responses. PMID- 29596453 TI - Sponges-Cyanobacteria associations: Global diversity overview and new data from the Eastern Mediterranean. AB - Sponge-cyanobacteria associations have attracted research interest from an ecological, evolutionary and biotechnological perspective. Current knowledge is, in its majority, "hidden" in metagenomics research studying the entire microbial communities of sponges, while knowledge on these associations is totally missing for certain geographic areas. In this study, we (a) investigated the occurrence of cyanobacteria in 18 sponge species, several of which are studied for the first time for their cyanobionts, from a previously unexplored eastern Mediterranean ecoregion, the Aegean Sea, (b) isolated sponge-associated cyanobacteria, and characterized them based on a polyphasic (morphological-morphometric and molecular phylogenetic analysis) approach, and (c) conducted a meta-analysis on the global diversity of sponge species hosting cyanobacteria, as well as the diversity of cyanobacterial symbionts. Our research provided new records for nine sponge species, previously unknown for this association, while the isolated cyanobacteria were found to form novel clades within Synechococcus, Leptolyngbyaceae, Pseudanabaenaceae, and Schizotrichaceae, whose taxonomic status requires further investigation; this is the first report of a Schizotrichaceae cyanobacterium associated with sponges. The extensive evaluation of the literature along with the new data from the Aegean Sea raised the number of sponge species known for hosting cyanobacteria to 320 and showed that the cyanobacterial diversity reported from sponges is yet underestimated. PMID- 29596454 TI - Classification of atrophic mucosal patterns on Blue LASER Imaging for endoscopic diagnosis of Helicobacter pylori-related gastritis: A retrospective, observational study. AB - BACKGROUND: Atrophic gastritis can be classified according to characteristic mucosal patterns observed by Blue LASER Imaging (BLI) in a medium-range to distant view. AIMS: To facilitate the endoscopic diagnosis of Helicobacter pylori (HP)-related gastritis, we investigated whether atrophic mucosal patterns correlated with HP infection based on the image interpretations of three endoscopists blinded to clinical features. METHODS: This study included 441 patients diagnosed as having atrophic gastritis by upper gastrointestinal endoscopy at Nishikawa Gastrointestinal Clinic between April 1, 2015 and March 31, 2016. The presence/absence of HP infection was not taken into consideration. Endoscopy was performed using a Fujifilm EG-L580NW scope. Atrophic mucosal patterns observed by BLI were classified into Spotty, Cracked and Mottled. Image interpretation results were that 89, 122 and 228 patients had the Spotty, Cracked and Mottled patterns, respectively, and 2 patients an undetermined pattern. Further analyses were performed on 439 patients, excluding the 2 with undetermined patterns. RESULTS: The numbers of patients testing negative/positive for HP infection in the Spotty, Cracked and Mottled pattern groups were 12/77, 105/17, and 138/90, respectively. The specificity, positive predictive value and positive likelihood ratio for endoscopic diagnosis with positive HP infection based on the Spotty pattern were 95.3%, 86.5% and 8.9, respectively. In all patients with the Spotty pattern before HP eradication, the Cracked pattern was observed on subsequent post-eradication endoscopy. CONCLUSIONS: The Spotty pattern may represent the presence of HP infection, the Cracked pattern, a post inflammatory change as seen after HP eradication, and the Mottled pattern, intestinal metaplasia. PMID- 29596455 TI - Flip-flop method: A new T1-weighted flow-MRI for plants studies. AB - The climate warming implies an increase of stress of plants (drought and torrential rainfall). The understanding of plant behavior, in this context, takes a major importance and sap flow measurement in plants remains a key issue for plant understanding. Magnetic Resonance Imaging (MRI) which is well known to be a powerful tool to access water quantity can be used to measure moving water. We describe a novel flow-MRI method which takes advantage of inflow slice sensitivity. The method involves the slice selectivity in the context of multi slice spin echo sequence. Two sequences such as a given slice is consecutively inflow and outflow sensitive are performed, offering the possiblility to perform slow flow sensitive imaging in a quite straigthforward way. The method potential is demonstrated by imaging both a slow flow measurement on a test bench (as low as 10 MUm.s-1) and the Poiseuille's profile of xylemian sap flow velocity in the xylematic tissues of a tomato plant stem. PMID- 29596456 TI - Modelling southern elephant seals Mirounga leonina using an individual-based model coupled with a dynamic energy budget. AB - Higher trophic-level species are an integral component of any marine ecosystem. Despite their importance, methods for representing these species in end-to-end ecosystem models often have limited representation of life histories, energetics and behaviour. We built an individual-based model coupled with a dynamic energy budget for female southern elephant seals Mirounga leonina to demonstrate a method for detailed representation of marine mammals. We aimed to develop a model which could i) simulate energy use and life histories, as well as breeding traits of southern elephant seals in an emergent manner, ii) project a stable population over time, and iii) have realistic population dynamics and structure based on emergent life history features (such as age at first breeding, lifespan, fecundity and (yearling) survival). We evaluated the model's ability to represent a stable population over long time periods (>10 generations), including the sensitivity of the emergent properties to variations in key parameters. Analyses indicated that the model is sensitive to changes in resource availability and energy requirements for the transition from pup to juvenile, and juvenile to adult stage. This was particularly the case for breeding success and yearling survival. This model is suitable for use as a standalone tool for investigating the impacts of changes to behaviour and population responses of southern elephant seals. PMID- 29596457 TI - Effects of functionalized multi-walled carbon nanotubes on toxicity and bioaccumulation of lead in Daphnia magna. AB - Increased production of carbon nanotubes (CNTs) and their widespread application in industrial and consumer products have led to a rise in the release of CNTs into the aquatic environment. CNTs have a very strong adsorption affinity for various environmental contaminants; therefore, they may also influence the toxic effects of other pollutants, such as toxic metals. In this study, the effect of two different functionalized carbon nanotubes, carboxylate and polyethyleneimine modified multi-walled carbon nanotubes (C-MWCNTs and N-MWCNT, respectively) on lead toxicity and bioaccumulation was investigated with a freshwater zooplankton Daphnia magna. The acute toxicity results indicate that the different surface properties of the two types of MWCNTs have different effects on lead toxicity to D. magna. The negatively charged C-MWCNT showed a notable decrease in lead toxicity (LC50 value increased from 0.15 mg L-1 to 1.08 mg L-1 in the presence of 10 mg L-1 C-MWCNT), whereas the positively charged N-MWCNT had only a slight effect on lead toxicity (LC50 value increased from 0.15 mg L-1 to 0.16 mg L-1 in the presence of 10 mg L-1 N-MWCNT). The decrease of lead toxicity was related with the reduced bioavailability of free metal form (Pb2+) caused by greater adsorption of lead onto the MWCNTs. The present study suggests that there is a need to consider carefully the complex interaction of CNTs with toxic metals in future ecotoxicological studies. PMID- 29596458 TI - Quantitative N-glycoproteomics reveals altered glycosylation levels of various plasma proteins in bloodstream infected patients. AB - Bloodstream infections are associated with high morbidity and mortality with rates varying from 10-25% and higher. Appropriate and timely onset of antibiotic therapy influences the prognosis of these patients. It requires the diagnostic accuracy which is not afforded by current gold standards such as blood culture. Moreover, the time from blood sampling to blood culture results is a key determinant of reducing mortality. No established biomarkers exist which can differentiate bloodstream infections from other systemic inflammatory conditions. This calls for studies on biomarkers potential of molecular profiling of plasma as it is affected most by the molecular changes accompanying bloodstream infections. N-glycosylation is a post-translational modification which is very sensitive to changes in physiology. Here we have performed targeted quantitative N-glycoproteomics from plasma samples of patients with confirmed positive blood culture together with age and sex matched febrile controls with negative blood culture reports. Three hundred and sixty eight potential N-glycopeptides were quantified by mass spectrometry and 149 were further selected for identification. Twenty four N-glycopeptides were identified with high confidence together with elucidation of the peptide sequence, N-glycosylation site, glycan composition and proposed glycan structures. Principal component analysis, orthogonal projections to latent structures-discriminant analysis (S-Plot) and self-organizing maps clustering among other statistical methods were employed to analyze the data. These methods gave us clear separation of the two patient classes. We propose high-confidence N-glycopeptides which have the power to separate the bloodstream infections from blood culture negative febrile patients and shed light on host response during bacteremia. Data are available via ProteomeXchange with identifier PXD009048. PMID- 29596459 TI - Clinicians' perspectives on incidentally discovered silent brain infarcts - A qualitative study. AB - BACKGROUND: While silent brain infarcts (SBIs) in screened cohorts are associated with risk of symptomatic stroke and dementia, the clinical significance of incidentally discovered SBIs (id-SBIs) is unknown. Detection may offer an opportunity to initiate prevention measures, but uncertainties about id-SBIs may impede clinicians from addressing them and complicate further study of this condition. METHODS AND RESULTS: This study used semi-structured interviews of practicing clinicians. Interviews were audio recorded, transcribed, and analyzed using a grounded theory approach. A constant comparative method was used to organize emergent themes and examine new themes. Purposeful sampling was employed to achieve participant diversity. Fifteen clinicians were interviewed. Emergent themes centered on uncertainty about id-SBIs, clinical decision making in response to uncertainty, and evidence needed to resolve uncertainty. All clinicians reported uncertainty about id-SBIs: diagnostic, prognostic, or therapeutic. Differential responses to uncertainties resulted in practice variation within and between specialties. Diagnostic and prognostic uncertainty discouraged disclosure of imaging findings to patients. Vascular neurologists viewed the prognostic significance of id-SBIs as similar to symptomatic stroke. Therapeutic uncertainty was common, but most participants endorsed using stroke secondary prevention strategies. Regarding future research, all internists indicated they would consider changing practices in response to observational studies, whereas half of the neurologists expressed reluctance to modify practices based on non-randomized data. Several expressed concerns about clinical trial feasibility and lack of equipoise. CONCLUSIONS: id-SBIs are a focus of uncertainty for clinicians, leading to practice variation. Future studies must address diagnostic and prognostic uncertainty to facilitate implementation of prevention strategies. PMID- 29596460 TI - Low-carbohydrate diets for type 1 diabetes mellitus: A systematic review. AB - Type 1 diabetes is an autoimmune condition characterised by pancreatic beta cell destruction and absolute insulin deficiency. The strongest predictor of diabetes complications is glycaemic control and achieving HbA1c <= 7.0% is the primary management target. However, standard treatment appears to be lacking and adjunctive strategies require consideration. A systematic review was conducted to examine the effect of low-carbohydrate diets on type 1 diabetes management. Four databases were searched from inception until 28 March 2017: MEDLINE; CINAHL; Cochrane Library; and EMBASE. All primary studies containing a methods section (excluding cross-sectional) were included. Reports had to quantitatively measure the effect(s) of a dietary intervention or observed intake over at least two weeks where carbohydrate is below 45% total energy in adults and/or children with type 1 diabetes. The primary outcome was HbA1c and secondary outcomes were severe hypoglycaemia, total daily insulin, BMI, quality of life and mean daily glucose. Seventy-nine full-text articles were assessed for eligibility and nine were included (two randomised controlled trials, four pre-post interventions, two case series, one case-report). Eight studies reported a mean change in HbA1c with a low-carbohydrate diet. Of these, four reported a non-significant change (P >= 0.05) and three reported statistically significant reductions (P < 0.05). Two studies reported severe hypoglycaemia, five reported total insulin, three reported BMI, and one reported blood glucose. Due to the significant heterogeneity of included studies, an overall effect could not be determined. This review presents all available evidence on low-carbohydrate diets for type 1 diabetes and suggests an urgent need for more primary studies. PMID- 29596461 TI - CT utilization abruptly increases at age 18 among patients with inflammatory bowel diseases in the hospital. AB - OBJECTIVES: Patients with inflammatory bowel disease(IBD) are frequently exposed to computed tomography (CT). Each CT exposes patients to radiation that cumulatively could increase the risk of malignancy, particularly in younger patients. We aim to study the effect of age on CT use in IBD patients seen in the Emergency Department (ED) or the hospital. METHODS: We conducted a retrospective cohort study of IBD patients identified in Truven Health Marketscan databases between 2009-2013. The main outcome was use of CT during an ED or inpatient visit. Effect of age on CT use was characterized using logistic regression accounting for important covariables. RESULTS: There were 66,731 patients with IBD with 144,147 ED or inpatient visits in this cohort with a diagnosis code of IBD. At first visit, 5.8% percent were below age 18. CT was utilized in 26.6% of visits. In multivariable analysis, adjusting for medications, recent surgery, and gender, patients 18-35 were more likely to undergo CT (OR 2.35, 95%CI: 2.20-2.52) compared to those <18. Examining patients only between 16 and 19, the odds of an 18 or 19-year-old undergoing CT is significantly higher than a 16 or 17-year-old (OR 1.96, 95%CI: 1.71-2.24). CONCLUSIONS: Patients with IBD undergo CT more than a quarter of the time in the ED or inpatient setting. Pediatric providers limit radiation exposure among those <18 while adult providers are not as cautious with radiation exposure for the young adult population. Increased awareness of the risks of cumulative radiation exposure in the young adult population is needed. PMID- 29596462 TI - Racial disparities in the prevalence and control of hypertension among a cohort of HIV-infected patients in the southeastern United States. AB - BACKGROUND: African Americans are disproportionately affected by both HIV and hypertension. Failure to modify risk factors for cardiovascular disease and chronic kidney disease such as hypertension among HIV-infected patients may attenuate the benefits conferred by combination antiretroviral therapy. In the general population, African Americans with hypertension are less likely to have controlled blood pressure than whites. However, racial differences in blood pressure control among HIV-infected patients are not well studied. METHODS: We conducted a cross-sectional study evaluating racial differences in hypertension prevalence, treatment, and control among 1,664 patients attending the University of Alabama at Birmingham HIV Clinic in 2013. Multivariable analyses were performed to calculate prevalence ratios (PR) with 95% confidence intervals (CI) as the measure of association between race and hypertension prevalence and control while adjusting for other covariates. RESULTS: The mean age of patients was 47 years, 77% were male and 54% African-American. The prevalence of hypertension was higher among African Americans compared with whites (49% vs. 43%; p = 0.02). Among those with hypertension, 91% of African Americans and 93% of whites were treated (p = 0.43). Among those treated, 50% of African Americans versus 60% of whites had controlled blood pressure (systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg) (p = 0.007). After multivariable adjustment for potential confounders, prevalence of hypertension was higher among African Americans compared to whites (PR 1.25; 95% CI 1.12-1.39) and prevalence of BP control was lower (PR 0.80; 95% CI 0.69-0.93). CONCLUSIONS: Despite comparable levels of hypertension treatment, African Americans in our HIV cohort were less likely to achieve blood pressure control. This may place them at increased risk for adverse outcomes that disproportionately impact HIV-infected patients, such as cardiovascular disease and chronic kidney disease, and thus attenuate the benefits conferred by combination antiretroviral therapy. PMID- 29596463 TI - Inhibin betaE (INHBE) is a possible insulin resistance-associated hepatokine identified by comprehensive gene expression analysis in human liver biopsy samples. AB - The liver plays a major role in whole-body energy homeostasis by releasing secretory factors, termed hepatokines. To identify novel target genes associated with insulin resistance, we performed a comprehensive analysis of gene expression profiles using a DNA chip method in liver biopsy samples from humans with varying degrees of insulin resistance. Inhibin betaE (INHBE) was identified as a novel putative hepatokine with hepatic gene expression that positively correlated with insulin resistance and body mass index in humans. Quantitative real time-PCR analysis also showed an increase in INHBE gene expression in independent liver samples from insulin-resistant human subjects. Additionally, Inhbe gene expression increased in the livers of db/db mice, a rodent model of type 2 diabetes. To preliminarily screen the role of Inhbe in vivo in whole-body energy metabolic status, hepatic mRNA was knocked down with siRNA for Inhbe (siINHBE) in db/db mice. Treatment with siINHBE suppressed body weight gain during the two week experimental period, which was attributable to diminished fat rather than lean mass. Additionally, treatment with siINHBE decreased the respiratory quotient and increased plasma total ketone bodies compared with treatment with non-targeting siRNA, both of which suggest enhanced whole-body fat utilization. Our study suggests that INHBE functions as a possible hepatokine to alter the whole-body metabolic status under obese insulin-resistant conditions. PMID- 29596464 TI - Potential geographic "hotspots" for drug-injection related transmission of HIV and HCV and for initiation into injecting drug use in New York City, 2011-2015, with implications for the current opioid epidemic in the US. AB - OBJECTIVE: We identified potential geographic "hotspots" for drug-injecting transmission of HIV and hepatitis C virus (HCV) among persons who inject drugs (PWID) in New York City. The HIV epidemic among PWID is currently in an "end of the epidemic" stage, while HCV is in a continuing, high prevalence (> 50%) stage. METHODS: We recruited 910 PWID entering Mount Sinai Beth Israel substance use treatment programs from 2011-2015. Structured interviews and HIV/ HCV testing were conducted. Residential ZIP codes were used as geographic units of analysis. Potential "hotspots" for HIV and HCV transmission were defined as 1) having relatively large numbers of PWID 2) having 2 or more HIV (or HCV) seropositive PWID reporting transmission risk-passing on used syringes to others, and 3) having 2 or more HIV (or HCV) seronegative PWID reporting acquisition risk injecting with previously used needles/syringes. Hotspots for injecting drug use initiation were defined as ZIP codes with 5 or more persons who began injecting within the previous 6 years. RESULTS: Among PWID, 96% injected heroin, 81% male, 34% White, 15% African-American, 47% Latinx, mean age 40 (SD = 10), 7% HIV seropositive, 62% HCV seropositive. Participants resided in 234 ZIP codes. No ZIP codes were identified as potential hotspots due to small numbers of HIV seropositive PWID reporting transmission risk. Four ZIP codes were identified as potential hotspots for HCV transmission. 12 ZIP codes identified as hotspots for injecting drug use initiation. DISCUSSION: For HIV, the lack of potential hotspots is further validation of widespread effectiveness of efforts to reduce injecting-related HIV transmission. Injecting-related HIV transmission is likely to be a rare, random event. HCV prevention efforts should include focus on potential hotspots for transmission and on hotspots for initiation into injecting drug use. We consider application of methods for the current opioid epidemic in the US. PMID- 29596466 TI - The changing relationship between marriage and childbearing in Hong Kong. AB - Births outside marriage (BoM) account for around 15% of all births globally. However, the distribution around the world is very uneven, as are cultural and political attitudes towards them. Studies from East Asia have shown that the percentage of such births is very low, with only modest increases in recent years. The orthodox demographic view holds that the maintenance of conservative views around the relationship between marriage and childbearing can play a role in keeping fertility low. Prenuptial pregnancies (PNP) (where births occur within eight months of marriage) have been identified as a growing phenomenon in Japan, possibly being an 'alternative' Asian pathway to family formation. As yet, no comprehensive statistical analysis of the trends of BoM or PNP has been performed for Hong Kong. Using a comprehensive microdata set of birth registration in Hong Kong from 1984-2015 (N = 1,680,831) we provide evidence of recent trends in such 'alternative pathways' to family formation and examine predictors through regression analysis. Our results indicate, in common with elsewhere in East Asia, low overall period rates of either BoM or PNP (although the latter has risen notably in recent years). While more recent birth cohorts exhibit higher prevalence of such births, their incomplete nature and higher expected propensity suggests that the figures are exaggerated. In our regression analysis, we find that lower educational attainment is a strong predictor of both BoM and PNP, suggesting that a bifurcation of experience may be occurring. This adds further evidence to the theory that the maintenance of traditional family formation systems in the context of revolutionised educational and work opportunities for women mean that the opportunity costs of the 'marriage package' become too high. Current disparities in rights and privileges between married and unmarried parents-and especially their children-means that targeted family planning services and support for vulnerable families are policy priorities. PMID- 29596465 TI - Homozygous KSR1 deletion attenuates morbidity but does not prevent tumor development in a mouse model of RAS-driven pancreatic cancer. AB - Given the frequency with which MAP kinase signaling is dysregulated in cancer, much effort has been focused on inhibiting RAS signaling for therapeutic benefit. KSR1, a pseudokinase that interacts with RAF, is a potential target; it was originally cloned in screens for suppressors of constitutively active RAS, and its deletion prevents RAS-mediated transformation of mouse embryonic fibroblasts. In this work, we used a genetically engineered mouse model of pancreatic cancer to assess whether KSR1 deletion would influence tumor development in the setting of oncogenic RAS. We found that Ksr1-/- mice on this background had a modest but significant improvement in all-cause morbidity compared to Ksr1+/+ and Ksr1+/- cohorts. Ksr1-/- mice, however, still developed tumors, and precursor pancreatic intraepithelial neoplastic (PanIN) lesions were detected within a similar timeframe compared to Ksr1+/+ mice. No significant differences in pERK expression or in proliferation were noted. RNA sequencing also did not reveal any unique genetic signature in Ksr1-/- tumors. Further studies will be needed to determine whether and in what settings KSR inhibition may be clinically useful. PMID- 29596467 TI - Circulating autoantibodies against neuroblastoma suppressor of tumorigenicity 1 (NBL1): A potential biomarker for coronary artery disease in patients with obstructive sleep apnea. AB - OBJECTIVE: Although severe obstructive sleep apnea (OSA) is an important risk factor for atherosclerosis-related diseases including coronary artery disease (CAD), there is no reliable biomarker of CAD risks in patients with OSA. This study aimed to test our hypothesis that circulating autoantibodies against neuroblastoma suppressor of tumorigenicity 1 (NBL1-Abs) are associated with the prevalence of CAD in patients with OSA. METHODS: Eighty-two adults diagnosed with OSA by polysomnography, 96 patients with a diagnosis of acute coronary syndrome (ACS) and 64 healthy volunteers (HVs) were consecutively enrolled. Serum samples were collected from patients with OSA at diagnostic polysomnography and from patients with ACS at disease onset. Serum NBL1-Ab level was measured by amplified luminescence proximity homogeneous assay and its association with clinical variables related to atherosclerosis was evaluated. RESULTS: NBL1-Ab level was significantly elevated in patients with both OSA and ACS compared with HVs. Subgroup analyses showed that NBL1-Ab level was markedly higher in patients with severe OSA and OSA patients with a history of CAD. Weak associations were observed between NBL1-Ab level and apnea-hypopnea index, age, mean SpO2 and arousal index, whereas significantly higher NBL1-Ab levels were observed in OSA patients with a history of CAD than in those without a history of CAD. Sensitivity analysis using a logistic regression model also demonstrated that increased NBL1-Ab levels were associated with the previous history of CAD in patients with OSA. CONCLUSIONS: Elevated NBL1-Ab levels may be associated with the prevalence of CAD in patients with OSA, which needs to be confirmed further. PMID- 29596468 TI - Investigation of the seasonal microbiome of Anopheles coluzzii mosquitoes in Mali. AB - The poorly understood mechanisms of dry season persistence of Anopheles spp. mosquitoes through the dry season in Africa remain a critical gap in our knowledge of Plasmodium disease transmission. While it is thought that adult mosquitoes remain in a dormant state throughout this seven-month dry season, the nature of this state remains unknown and has largely not been recapitulated in laboratory settings. To elucidate possible connections of this state with microbial composition, the whole body microbiomes of adult mosquitoes in the dry and wet seasons in two locations of Mali with varying water availability were compared by sequencing the 16S ribosomal RNA gene. These locations were a village near the Niger River with year-round water sources (N'Gabakoro, "riparian"), and a typical Sahelian area with highly seasonal breeding sites (Thierola Area, "Sahelian"). The 16S bacterial data consisted of 2057 sequence variants in 426 genera across 184 families. From these data, we found several compositional differences that were seasonally and spatially linked. Counter to our initial hypothesis, there were more pronounced seasonal differences in the bacterial microbiome of riparian, rather than Sahelian areas. These seasonal shifts were primarily in Ralstonia, Sphingorhabdus, and Duganella spp. bacteria that are usually soil and water-associated, indicating these changes may be from bacteria acquired in the larval environment, rather than adulthood. In Sahelian dry season mosquitoes, there was a unique intracellular bacteria, Anaplasma, which likely was acquired through non-human blood feeding. Cytochrome B analysis of blood meals showed greater heterogeneity in host choice of An. coluzzii independent of season in the Thierola area compared to N'Gabakoro (77.5% vs. 94.6% human-origin blood meal, respectively), indicating a relaxation of anthropophily. Overall, this exploratory study provides valuable indications of spatial and seasonal differences in bacterial composition which help refine this difficult to study state. PMID- 29596469 TI - Low SOX2 expression marks a distinct subset of adenoid cystic carcinoma of the head and neck and is associated with an advanced tumor stage. AB - INTRODUCTION: The transcription factor SOX2 has been identified as a lineage survival oncogene in squamous cell carcinoma and copy number gain is a common event in several human malignancies including head and neck cancer. However, the regulation and function of SOX2 during carcinogenesis as well as its prognostic value appears to be highly context dependent. As an example, high SOX2 expression in lung squamous cell carcinoma (SCC) is related to a favorable prognosis, while it is associated with poor outcome in lung adenocarcinoma. More recently, higher SOX2 levels and improved survival was also reported for head and neck SCC (HNSCC), and silencing of SOX2 expression in HNSCC cell lines revealed a mesenchymal-like phenotype with prominent vimentin expression. So far, SOX2 expression and its clinical relevance for other head and neck cancers, such as adenoid cystic carcinoma (HNACC) have not been sufficiently investigated. MATERIAL AND METHODS: SOX2, vimentin and E-cadherin expression was assessed by immunohistochemical staining on serial sections from formalin fixed and paraffin embedded tissue samples of a patient cohort (n = 45) with primary ACC and correlated with patient and tumor characteristics as well as survival. RESULTS: High SOX2 expression was found in 14 (31%) primary tumor specimens and was significantly correlated with a N0 lymph node status (p = 0.04), while low SOX2 expression was correlated with a solid growth pattern (p = 0.031). Of the 45 patients, 27 tumor samples resembled an EMT-like phenotype, as assessed by high vimentin and low E-cadherin levels. However, in HNACC SOX2 levels were neither correlated with vimentin nor with E-cadherin expression, further supporting a context dependent regulation and function of SOX2 in distinct tumor entities. CONCLUSION: The absence of SOX2 was predominantly found in solid HNACC, which are characterized by a more aggressive phenotype in ACC. However, the underlying molecular mechanisms of SOX2 regulation and function in distinct HNACC subgroups remain to be fully elucidated. PMID- 29596470 TI - Dysfunction in the mitochondrial Fe-S assembly machinery leads to formation of the chemoresistant truncated VDAC1 isoform without HIF-1alpha activation. AB - Biogenesis of iron-sulfur clusters (ISC) is essential to almost all forms of life and involves complex protein machineries. This process is initiated within the mitochondrial matrix by the ISC assembly machinery. Cohort and case report studies have linked mutations in ISC assembly machinery to severe mitochondrial diseases. The voltage-dependent anion channel (VDAC) located within the mitochondrial outer membrane regulates both cell metabolism and apoptosis. Recently, the C-terminal truncation of the VDAC1 isoform, termed VDAC1-DeltaC, has been observed in chemoresistant late-stage tumor cells grown under hypoxic conditions with activation of the hypoxia-response nuclear factor HIF-1alpha. These cells harbored atypical enlarged mitochondria. Here, we show for the first time that depletion of several proteins of the mitochondrial ISC machinery in normoxia leads to a similar enlarged mitochondria phenotype associated with accumulation of VDAC1-DeltaC. This truncated form of VDAC1 accumulates in the absence of HIF-1alpha and HIF-2alpha activations and confers cell resistance to drug-induced apoptosis. Furthermore, we show that when hypoxia and siRNA knock down of the ISC machinery core components are coupled, the cell phenotype is further accentuated, with greater accumulation of VDAC1-DeltaC. Interestingly, we show that hypoxia promotes the downregulation of several proteins (ISCU, NFS1, FXN) involved in the early steps of mitochondrial Fe-S cluster biogenesis. Finally, we have identified the mitochondria-associated membrane (MAM) localized Fe-S protein CISD2 as a link between ISC machinery downregulation and accumulation of anti-apoptotic VDAC1-DeltaC. Our results are the first to associate dysfunction in Fe-S cluster biogenesis with cleavage of VDAC1, a form which has previously been shown to promote tumor resistance to chemotherapy, and raise new perspectives for targets in cancer therapy. PMID- 29596471 TI - Predicting dementia from primary care records: A systematic review and meta analysis. AB - INTRODUCTION: Possible dementia is usually identified in primary care by general practitioners (GPs) who refer to specialists for diagnosis. Only two-thirds of dementia cases are currently recorded in primary care, so increasing the proportion of cases diagnosed is a strategic priority for the UK and internationally. Variables in the primary care record may indicate risk of developing dementia, and could be combined in a predictive model to help find patients who are missing a diagnosis. We conducted a meta-analysis to identify clinical entities with potential for use in such a predictive model for dementia in primary care. METHODS AND FINDINGS: We conducted a systematic search in PubMed, Web of Science and primary care database bibliographies. We included cohort or case-control studies which used routinely collected primary care data, to measure the association between any clinical entity and dementia. Meta analyses were performed to pool odds ratios. A sensitivity analysis assessed the impact of non-independence of cases between studies. From a sift of 3836 papers, 20 studies, all European, were eligible for inclusion, comprising >1 million patients. 75 clinical entities were assessed as risk factors for all cause dementia, Alzheimer's (AD) and Vascular dementia (VaD). Data included were unexpectedly heterogeneous, and assumptions were made about definitions of clinical entities and timing as these were not all well described. Meta-analysis showed that neuropsychiatric symptoms including depression, anxiety, and seizures, cognitive symptoms, and history of stroke, were positively associated with dementia. Cardiovascular risk factors such as hypertension, heart disease, dyslipidaemia and diabetes were positively associated with VaD and negatively with AD. Sensitivity analyses showed similar results. CONCLUSIONS: These findings are of potential value in guiding feature selection for a risk prediction tool for dementia in primary care. Limitations include findings being UK-focussed. Further predictive entities ascertainable from primary care data, such as changes in consulting patterns, were absent from the literature and should also be explored in future studies. PMID- 29596472 TI - Evaluation of nationwide supplementary immunization in Lao People's Democratic Republic: Population-based seroprevalence survey of anti-measles and anti-rubella IgG in children and adults, mathematical modelling and a stability testing of the vaccine. AB - BACKGROUND: Measles outbreaks have occurred in some countries despite supplementary immunization activities (SIA) using measles-containing vaccine with high vaccination coverage. We conducted a cross-sectional seroprevalence survey to estimate population immunity in Lao People's Democratic Republic where repeated mass immunization has failed to eliminate measles. METHODS AND FINDINGS: In this nationwide multistage cluster sampling survey conducted in 2014 based on probability proportionate to size sampling, blood samples were collected from 2,135 children and adults living in 52 randomly selected villages. Anti-measles and anti-rubella IgG were measured, and IgG prevalence was calculated. We applied mathematical modelling to estimate the number of cases of congenital rubella syndrome (CRS) in 2013 that were averted by the 2011 SIA. A stability testing was applied to the MR vaccine at 4 degrees C, 25 degrees C, and 35 degrees C to examine stability differences between measles and rubella vaccine components. Measles IgG prevalence was significantly lower in the target age groups (5-21 years) of the 2011 SIA using a combination vaccine for measles and rubella vaccine (MR vaccine) than in young adults (22-39 years) (86.8% [95% CI: 83.0 90.6] vs. 99.0% [98.3-99.8]; p<0.001), whereas rubella IgG prevalence was significantly higher (88.2% [84.5-91.8] vs. 74.6% [70.7-78.5]; p<0.001). In the SIA target age groups, prevalence of measles IgG, but not rubella IgG, increased with age. CRS cases prevented in 2013 ranged from 16 [0-50] to 92 [32-180] if the force of infection had remained unchanged or had been reduced by 75%, respectively. In freeze-dried conditions, the measles vaccine component was more heat sensitive than the rubella component. CONCLUSIONS: Inconsistent IgG prevalence between measles and rubella in Lao PDR can be partly explained by different stability of the measles and rubella vaccine components under heat exposure. Suboptimal vaccine handling may cause insufficient immunogenicity for measles, which subsequently leads to an outbreak despite high SIA coverage, while direct evidence is lacking. Temperature monitoring of the vaccine should be conducted. PMID- 29596473 TI - Psychoactive substances and violent offences: A retrospective analysis of presentations to an urban emergency department in Switzerland. AB - BACKGROUND: Psychoactive substances are often regarded as causal factors contributing to violent injuries, sexual abuse and homicides. While these effects have been demonstrated for some substances (e.g. cocaine), current available data for others are more controversial (e.g. cannabis) or very limited (e.g. ecstasy). AIMS OF THE STUDY: To collect data on the type and frequency of psychoactive substance use in cases of emergency department (ED) presentations related to interpersonal violence. METHODS: Retrospective study at the University Hospital of Bern, Switzerland, between May 2012 and June 2016. The study covered cases of violent crime associated with psychoactive substances. Cases of isolated ethanol intoxication, suicide attempts, and substance use for medical purposes were excluded. RESULTS: The study included 103 cases among the 164,846 ED attendances. In the majority of the cases, the type of violence was bodily force (52%) related to urban violence (83%). The mean patient age was 29 years and 79% were male. 63% of the patients reported use of more than one drug; alcohol co-use was reported in 60% of the cases. Besides alcohol, the substances most often reported were cannabis (50%) and cocaine (21%). Alcohol and cannabis was also the most commonly reported substance combination (36% of the total cases). Urine drug screening was performed in 34% of the cases and cannabis and cocaine were the most commonly detected substances (46% and 19%, respectively). There were no cases of novel substances. 23% of the patients were admitted to a hospital ward, 10% to a psychiatric clinic. CONCLUSION: Cannabis and cocaine were, besides alcohol, the substances most often reported in ED presentations related to offences of violence. Because of the high prevalence of alcohol co-use, no final conclusions can be drawn on the contribution of single substances. PMID- 29596474 TI - Phloem transport capacity of transgenic rice T1c-19 (Cry1C*) under several potassium fertilizer levels. AB - Genetic modification of Cry-proteins from Bacillus thuringiensis (Bt) is a common practice in economically important crops to improve insecticide resistance and reduce the use of pesticides. However, introduction of these genes can have unintended side effects, which should be closely monitored for effective breeding and crop management. To determine the potential cause of these negative effects, we explored assimilate partitioning in the transgenic Bt rice line T1c-19 (Cry1C*), which was compared with that of its wild-type counterpart Minghui 63 (MH63) under different potassium fertilization application treatment conditions. In a pot experiment, 0, 0.4, and 0.6 g K2O was applied per kg of dry soil to determine the phloem transport characteristics of the two rice lines. We used a variety of assessment indicators ranging from morphological to physiological aspects, including the number of large and small vascular bundles in the neck internode at the heading stage, the diameter and bleeding intensity of the neck internode at the filling stage, and the content and apparent ratio of transferred non-structural carbohydrates (NSC) in the culm and sheath from the heading to maturing stages. The K utilization and grain yield at the maturing stage were also concerned. Results presented that the mean setting rate and grain yield of T1c-19 (Cry1C*) decreased by 22.3% and 26.2% compared to those in MH63, respectively. Compared to MH63, the K concentration and accumulation were significantly higher in the culms and leaves, but significantly lower in grain of T1c-19 (Cry1C*). T1c-19 (Cry1C*) had less apparent NSC efflux in the culm and sheath, fewer small vascular bundles, and a smaller diameter and bleeding intensity of the neck internode than MH63. In addition, linear correlation analysis indicated that there were positive correlations among grain yield, setting rate, the apparent NSC efflux in the culm and sheath, number of small vascular bundles, and the neck internode diameter and bleeding intensity. These unintended effects may directly or indirectly be caused by insertion of exogenous Bt (Cry1C*) gene, which should be further considered in the future breeding of transgenic crops. PMID- 29596475 TI - Sensitivity of different MRI sequences in the early detection of melanoma brain metastases. AB - BACKGROUND: After the emergence of new MRI techniques such as susceptibility- and diffusion-weighted imaging (SWI and DWI) and because of specific imaging characteristics of melanoma brain metastases (MBM), it is unclear which MRI sequences are most beneficial for detection of MBM. This study was performed to investigate the sensitivity of six clinical MRI sequences in the early detection of MBM. METHODS: Medical records of all melanoma patients referred to our center between November 2005 and December 2016 were reviewed for presence of MBM. Analysis encompassed six MRI sequences at the time of initial diagnosis of first or new MBM, including non-enhanced T1-weighted (T1w), contrast-enhanced T1w (ceT1w), T2-weighted (T2w), T2w-FLAIR, susceptibility-weighted (SWI) and diffusion-weighted (DWI) MRI. Each lesion was rated with respect to its conspicuity (score from 0-not detectable to 3-clearly visible). RESULTS: Of 1210 patients, 217 with MBM were included in the analysis and up to 5 lesions per patient were evaluated. A total of 720 metastases were assessed and all six sequences were available for 425 MBM. Sensitivity (conspicuity >=2) was 99.7% for ceT1w, 77.0% for FLAIR, 64.7% for SWI, 61.0% for T2w, 56.7% for T1w, and 48.4% for DWI. Thirty-one (7.3%) of 425 lesions were only detectable by ceT1w but no other sequence. CONCLUSIONS: Contrast-enhanced T1-weighting is more sensitive than all other sequences for detection of MBM. Disruption of the blood-brain barrier is consistently an earlier sign in MBM than perifocal edema, signal loss on SWI or diffusion restriction. PMID- 29596476 TI - The colonic epithelium plays an active role in promoting colitis by shaping the tissue cytokine profile. AB - Inflammatory bowel disease (IBD) is a chronic condition driven by loss of homeostasis between the mucosal immune system, the commensal gut microbiota, and the intestinal epithelium. Our goal is to understand how these components of the intestinal ecosystem cooperate to control homeostasis. By combining quantitative measures of epithelial hyperplasia and immune infiltration with multivariate analysis of inter- and intracellular signaling, we identified epithelial mammalian target of rapamycin (mTOR) signaling as a potential driver of inflammation in a mouse model of colitis. A kinetic analysis of mTOR inhibition revealed that the pathway regulates epithelial differentiation, which in turn controls the cytokine milieu of the colon. Consistent with our in vivo analysis, we found that cytokine expression of organoids grown ex vivo, in the absence of bacteria and immune cells, was dependent on differentiation state. Our study suggests that proper differentiation of epithelial cells is an important feature of colonic homeostasis because of its effect on the secretion of inflammatory cytokines.

AB - Identifying trauma patients at risk of imminent hemorrhagic shock is a challenging task in intraoperative and battlefield settings given the variability of traditional vital signs, such as heart rate and blood pressure, and their inability to detect blood loss at an early stage. To this end, we acquired N = 58 photoplethysmographic (PPG) recordings from both trauma patients with suspected hemorrhage admitted to the hospital, and healthy volunteers subjected to blood withdrawal of 0.9 L. We propose four features to characterize each recording: goodness of fit (r2), the slope of the trend line, percentage change, and the absolute change between amplitude estimates in the heart rate frequency range at the first and last time points. Also, we propose a machine learning algorithm to distinguish between blood loss and no blood loss. The optimal overall accuracy of discriminating between hypovolemia and euvolemia was 88.38%, while sensitivity and specificity were 88.86% and 87.90%, respectively. In addition, the proposed features and algorithm performed well even when moderate blood volume was withdrawn. The results suggest that the proposed features and algorithm are suitable for the automatic discrimination between hypovolemia and euvolemia, and can be beneficial and applicable in both intraoperative/emergency and combat casualty care.

AB - Hearing loss is the most common sensory impairment, but limited studies focused on the association of socioeconomic status (SES) with hearing loss among adults of working age. This paper aimed to fill this gap among Chinese adults. We obtained data from Ear and Hearing Disorder Survey conducted in four provinces of China in 2014-2015. The survey was based on WHO Ear and Hearing Disorders Survey Protocol and 25,860 adults aged 25 to 59 years were selected in this study. Trained local examiners performed pure tone audiometry to screen people with hearing loss, and those who were screened positively for hearing loss were referred to audiologists to make final diagnosis. SES was measured by occupation, education and income. Results show after adjusting for SES measures and covariates, in urban areas, compared with white-collar workers, blue-collar workers and the unemployed were more likely to have hearing loss, with an odds ratio of 1.2 (95%CI: 1.0, 1.3) and 1.2 (95%CI: 1.0, 1.4), respectively. Compared with people with education of senior high school or above, those with junior high school, primary school and illiteracy had 1.6 (95%CI: 1.4, 1.8), 2.1(95%CI: 1.7, 2.5) and 2.6 (95%CI: 1.9, 3.7) times as likely to have hearing loss, respectively. In rural areas, the unemployed had 1.5 (95%CI: 1.0, 2.3) times the risk of hearing loss compared with white-collar workers, and illiterates had 1.6 (95%CI: 1.6, 2.1) times the risk of hearing loss compared with people with education of senior high school or above, after SES variables and covariates were taken into considerations. Income was not significantly associated with hearing loss in urban and rural areas. In conclusion, SES, in the form of occupation and education, was associated with hearing loss among working-aged population, and further studies are needed to explore the mechanism of such association. PMID- 29596479 TI - The immediate effects of a single autogenic drainage session on ventilatory mechanics in adult subjects with cystic fibrosis. AB - INTRODUCTION: The aim of this study was to gain insight into the physiological changes occurring in subjects with cystic fibrosis (CF) after autogenic drainage (AD). Changes in respiratory system resistance (Rrs), reactance (Xrs), and spirometry were analyzed in adult CF subjects after a single AD physiotherapy session. METHODS: This prospective observational study was conducted during the annual check-up of adult CF subjects in stable condition. Spirometry and Rrs and Xrs measurements using the forced oscillations technique at 5, 11, and 19 hertz (Hz) were performed before and 30 min after a 20-min AD session. Control CF subjects were tested at baseline and 50 min without AD. Results are expressed as mean +/- standard deviation or median [interquartile range]. RESULTS: Thirty subjects were included in the physiotherapy group (age 29 [25-34] years, forced expiratory volume in 1 s (FEV1) 40.3 [30.1-57.9]% predicted) and 11 in the control group (age 31 [28.5-36.5] years, FEV1 43.6 [31.1-51.9] % predicted). No significant changes in any parameter were observed in the control group. AD modestly but significantly increased the forced vital capacity (FVC) and FEV1 (p<0.001). Inspiratory resistance was also significantly improved by AD: Rrs5 from 5.74+/-2.39 to 5.24+/-2.17 cmH2O/L/s, p<0.05; Rrs11 from 4.83+/-1.98 to 4.32+/-1.7 cmH2O/L/s, p = 0.003; and Rrs19 from 4.18 [3.46-5.07] to 3.86 [2.76 4.98] cmH2O/L/s, p<0.001. In contrast, AD had no significant effects on frequency dependence of resistance (Rrs5-Rrs19) or expiratory resistance. Inspiratory Xrs5, but not DeltaXrs5 (expiratory-inspiratory Xrs), was improved by AD (p<0.05). Moderate correlations were detected between the improvement in FEV1 and FVC and inspiratory resistance (r = 0.53, p = 0.005 and r = 0.44, p = 0.02, respectively). CONCLUSION: A single session of AD improved inspiratory airway resistance, except in the distal airways. The forced oscillations technique provides a new tool for understanding the pathophysiological effects of airway clearance physiotherapy in CF.

AB - INTRODUCTION: This study aimed to determine the intra- and inter-session reliability of neuromuscular assessment of plantar flexor (PF) muscles at three knee angles. METHODS: Twelve young adults were tested for three knee angles (90 degrees , 30 degrees and 0 degrees ) and at three time points separated by 1 hour (intra-session) and 7 days (inter-session). Electrical (H reflex, M wave) and mechanical (evoked and maximal voluntary torque, activation level) parameters were measured on the PF muscles. Intraclass correlation coefficients (ICC) and coefficients of variation were calculated to determine intra- and inter-session reliability. RESULTS: The mechanical measurements presented excellent (ICC>0.75) intra- and inter-session reliabilities regardless of the knee angle considered. The reliability of electrical measurements was better for the 90 degrees knee angle compared to the 0 degrees and 30 degrees angles. CONCLUSIONS: Changes in the knee angle may influence the reliability of neuromuscular assessments, which indicates the importance of considering the knee angle to collect consistent outcomes on the PF muscles. PMID- 29596481 TI - Neck dissection does not increases the risk of stroke in thyroid cancer: A national cohort study. AB - OBJECTIVES: The purpose of this study is to evaluate the risk of stroke (hemorrhagic or ischemic) after neck dissection in thyroid cancer patients in Korea using national cohort data. METHODS: Using the national cohort study from the Korean Health Insurance Review and Assessment Service, patients with neck dissection for thyroid cancer (1,041) and control participants (4,164) were selected and matched 1:4 (age, gender, income, and region of residence). The Chi square test, Fischer's exact test, and the Cox-proportional hazard model were used. The Cox-proportional analysis used a crude model and an adjusted model for age, gender, income, region of residence, hypertension, diabetes, dyslipidemia. RESULTS: None of the participants had suffered hemorrhagic stroke in the neck dissection group, while 0.3% (13/4,164) of participants had suffered hemorrhagic stroke in the control group (P = 0.085). In total, 0.8% (8/1,041) of participants had suffered an ischemic stroke in the neck dissection group, and 0.7% (31/4,133) of participants had suffered an ischemic stroke in the control group (P = 0.936). The adjusted hazard ratio for ischemic stroke after neck dissection was 1.06 (95% confidence interval [CI] = 0.49-2.31, P = 0.884). CONCLUSION: The risk of hemorrhagic or ischemic stroke was not higher in thyroid cancer patients who underwent neck dissection than that in the matched control group.

AB - Rapid urbanization coupled with decreasing areas of natural habitat are causing baboon populations to become scattered and isolated, often resulting in increased levels of human-baboon conflict. To implement baboon-human conflict management strategies, it is essential to formulate realistic conservation policies that deal with all stakeholder concerns and ensure the conservation of viable baboon populations. A study was initiated in response to complaints of perceived excessive baboon numbers and associated lack of food resources on Suikerbosrand Nature Reserve in South Africa. Data obtained from GPS tracking collars fitted to one baboon from each of 10 identified troops were analyzed to determine home range size and utilization. The spatial representation of home ranges generated from this study will allow reserve management to identify areas of potential high and low human-baboon conflict and will contribute to the development of a formal baboon management plan to reduce human-baboon conflict on and around the reserve. Home ranges were unevenly distributed and had a mean size of 26.72 km2 +/- 13.91 SD in the cold/dry season and 26.54 km2 +/- 12.76 SD in the warm/wet season. Troop home ranges overlapped to some degree and five troops utilized areas outside the reserve. Although no significant relationship between troop size and home range was found, there was a positive relationship between troop size and daily distance travelled. All troops had significantly longer mean daily distances during the warm/wet season than during the cold/dry season (P <= 0.02). PMID- 29596483 TI - Development of post-disaster psychosocial evaluation and intervention for children: Results of a South Korean delphi panel survey. AB - OBJECTIVE: This study aimed to administer a Delphi panel survey and provide evidence for the development of a psychological intervention protocol for use after disasters in South Korea. METHOD: A three-round Delphi survey was conducted. In all rounds, respondents answered open- or closed-ended questions regarding their views on i) the concept of disaster, ii) evaluation, iii) intervention, and iv) considerations in a disaster. Data from Round 1 were subjected to content analysis. In Round 2, items with content validity ratios (CVRs) greater than 0.49 were included, and in Round 3, items with a CVR>=0.38 were accepted. RESULTS: The response rates for the Delphi survey were high: 83% (n = 15, Round 1), 80% (n = 16, Round 2), and 86% (n = 24, Round 3). The data collected during this survey showed a need for a support system for children; for preventive strategies, including disaster readiness plans; for the protection of children's safety; and for the development of post-disaster psychosocial care. CONCLUSIONS: The panel experts reached a consensus regarding the steps they considered critical in post-disaster evaluation and intervention. The findings suggest a unified model for advancing the development of the Korean version of an intervention protocol for children and adolescents exposed to traumatic events. PMID- 29596484 TI - First quantification of subtidal community structure at Tristan da Cunha Islands in the remote South Atlantic: from kelp forests to the deep sea. AB - Tristan da Cunha Islands, an archipelago of four rocky volcanic islands situated in the South Atlantic Ocean and part of the United Kingdom Overseas Territories (UKOTs), present a rare example of a relatively unimpacted temperate marine ecosystem. We conducted the first quantitative surveys of nearshore kelp forests, offshore pelagic waters and deep sea habitats. Kelp forests had very low biodiversity and species richness, but high biomass and abundance of those species present. Spatial variation in assemblage structure for both nearshore fish and invertebrates/algae was greatest between the three northern islands and the southern island of Gough, where sea temperatures were on average 3-4o colder. Despite a lobster fishery that provides the bulk of the income to the Tristan islands, lobster abundance and biomass are comparable to or greater than many Marine Protected Areas in other parts of the world. Pelagic camera surveys documented a rich biodiversity offshore, including large numbers of juvenile blue sharks, Prionace glauca. Species richness and abundance in the deep sea is positively related to hard rocky substrate and biogenic habitats such as sea pens, crinoids, whip corals, and gorgonians were present at 40% of the deep camera deployments. We observed distinct differences in the deep fish community above and below ~750 m depth. Concurrent oceanographic sampling showed a discontinuity in temperature and salinity at this depth. While currently healthy, Tristan's marine ecosystem is not without potential threats: shipping traffic leading to wrecks and species introductions, pressure to increase fishing effort beyond sustainable levels and the impacts of climate change all could potentially increase in the coming years. The United Kingdom has committed to protection of marine environments across the UKOTs, including Tristan da Cunha and these results can be used to inform future management decisions as well as provide a baseline against which future monitoring can be based. PMID- 29596485 TI - Predicting financial market crashes using ghost singularities. AB - We analyse the behaviour of a non-linear model of coupled stock and bond prices exhibiting periodically collapsing bubbles. By using the formalism of dynamical system theory, we explain what drives the bubbles and how foreshocks or aftershocks are generated. A dynamical phase space representation of that system coupled with standard multiplicative noise rationalises the log-periodic power law singularity pattern documented in many historical financial bubbles. The notion of 'ghosts of finite-time singularities' is introduced and used to estimate the end of an evolving bubble, using finite-time singularities of an approximate normal form near the bifurcation point. We test the forecasting skill of this method on different stochastic price realisations and compare with Monte Carlo simulations of the full system. Remarkably, the approximate normal form is significantly more precise and less biased. Moreover, the method of ghosts of singularities is less sensitive to the noise realisation, thus providing more robust forecasts. PMID- 29596486 TI - Psychometric properties of the Czech version of the Stigma Scale of Epilepsy. AB - Although significant attention has been devoted to analyzing stigma associated with epilepsy, there is still a significant lack of valid and reliable instruments. We aimed to validate the 23-item Czech version of the Stigma Scale of Epilepsy (SSE; originally developed in Brazil), which has been used to evaluate epilepsy-related stigma in the general population. Verification of the SSE questionnaire was carried out in a group of 207 students aged 15-18 years of whom none had epilepsy. These students completed the SSE twice in a period of 3-6 months as part of standard test-retest evaluation practice. The instrument exhibits good psychometric properties including internal consistency higher than in the original version (Cronbach's alpha of 0.856 here compared with 0.81 reported in Brazil) and acceptable test-retest reliability. Using exploratory factor analysis (not provided for the original version), four factors were identified and corresponding subscales were described and interpreted. Two items did not fit into the structure and were eliminated. Confirmatory factor analysis was used to propose and verify the hierarchical 4-factor structure of the Czech version of SSE confirming the existence of a common factor corresponding to stigma. The results showed that the Czech version of SSE has good psychometric properties and can be used in further research and clinical practice. PMID- 29596487 TI - Involvement of the olfactory system in the induction of anti-fatigue effects by odorants. AB - Some components of the neural circuits underlying innate odor-evoked responses have recently been elucidated. Odor information detected by the olfactory receptors is transmitted from the olfactory bulb to the cortical amygdala, where physiological and emotional states such as attraction or avoidance are controlled. Thus, activation of specific olfactory receptors can elicit changes in physiological and/or psychological state. Here, we examined on the odorant Hex Hex Mix, which has been reported to induce anti-fatigue effects. Fatigue is a prevalent condition that is often related to overwork and psychological stress. Various anti-fatigue treatments have been developed, including supplements and odorants. However, the mechanisms underlying the anti-fatigue effects of these substances are currently unclear. In the present study, we analyzed the involvement of the olfactory system in the mechanisms underlying this effect. We identified the human olfactory receptors activated by Hex-Hex Mix, and evaluated whether activation of these olfactory receptors by a newly developed odorant elicited a similar anti-fatigue effect to Hex-Hex Mix. We assessed anti-fatigue effects with behavioral tests, and 17 healthy males performed the 2-back test as a fatigue-inducing task with or without exposure to the new odorant. Immediately before and after the task, participants performed a cognitive task to evaluate their level of mental fatigue. We found that the difference value of the correct response rate on the cognitive task in the evaluation session was significantly different between in the odorant condition and in the without-odorant condition during the fatigue-inducing session suggesting that the new odorant may improve performance in the fatigue-inducing condition. The results indicated that the new odorant activates the same olfactory receptors as Hex-Hex Mix, which has been reported to induce anti-fatigue effects. Our findings suggest that the olfactory receptors in the olfactory system may be involved in the attenuation of fatigue. PMID- 29596488 TI - Understanding a successful obesity prevention initiative in children under 5 from a systems perspective. AB - INTRODUCTION/BACKGROUND: Systems thinking represents an innovative and logical approach to understanding complexity in community-based obesity prevention interventions. We report on an approach to apply systems thinking to understand the complexity of a successful obesity prevention intervention in early childhood (children aged up to 5 years) conducted in a regional city in Victoria, Australia. METHODS: A causal loop diagram (CLD) was developed to represent system elements related to a successful childhood obesity prevention intervention in early childhood. Key stakeholder interviews (n = 16) were examined retrospectively to generate purposive text data, create microstructures, and form a CLD. RESULTS: A CLD representing key stakeholder perceptions of a successful intervention comprised six key feedback loops explaining changes in project implementation over time. The loops described the dynamics of collaboration, network formation, community awareness, human resources, project clarity, and innovation. CONCLUSION: The CLD developed provides a replicable means to capture, evaluate and disseminate a description of the dynamic elements of a successful obesity prevention intervention in early childhood. PMID- 29596490 TI - Critical in vivo roles of WNT10A in wound healing by regulating collagen expression/synthesis in WNT10A-deficient mice. AB - BACKGROUND: We have reported that WNT10A plays a critical role in the growth of fibroblasts/myofibroblasts and microvascular endothelial cells, i.e.; wound healing/scarring. To ascertain the in vivo regulatory, central functions of WNT10A, we examined the net effects of WNT10A depletion using WNT10A-deficient mice (WNT10A-/-). METHODS AND RESULTS: We generated WNT10A-/-mice, displaying a range of unique phenotypes of morpho/organogenetic failure, such as growth retardation, alopecia, kyphosis and infertility, and then focused on the functions of WNT10A in wound healing. We subjected C57BL/6J wild-type (WT) or WNT10A-/-mice to skin ulcer formation. The WNT10A-/-mice had significantly larger injured areas and delayed wound healing, which were associated with (a) a smaller number of fibroblasts/myofibroblasts and microvessels; and (b) more reduced expression and synthesis of collagen, compared with WT mice with intact WNT10A expression, especially in those with activated myofibroblasts. CONCLUSIONS: These observations indicate that WNT10A signaling can play a pivotal in vivo role in wound healing by regulating the expression and synthesis of collagen, as one of fibrogenic factors, at least in part, and critical in vivo roles of WNT10A mediated effective wound healing are extremely closely associated with collagen expression. PMID- 29596489 TI - A Boolean network of the crosstalk between IGF and Wnt signaling in aging satellite cells. AB - Aging is a complex biological process, which determines the life span of an organism. Insulin-like growth factor (IGF) and Wnt signaling pathways govern the process of aging. Both pathways share common downstream targets that allow competitive crosstalk between these branches. Of note, a shift from IGF to Wnt signaling has been observed during aging of satellite cells. Biological regulatory networks necessary to recreate aging have not yet been discovered. Here, we established a mathematical in silico model that robustly recapitulates the crosstalk between IGF and Wnt signaling. Strikingly, it predicts critical nodes following a shift from IGF to Wnt signaling. These findings indicate that this shift might cause age-related diseases. PMID- 29596492 TI - The prevalence of Yersinia enterocolitica in game animals in Poland. AB - Natural reservoirs of Yersinia (Y.) enterocolitica comprise different animal species, but little is known about the role of wild animals in the epidemiology of yersiniosis. The aim of the study was to evaluate the prevalence of Y. enterocolitica among game animals in Poland. The bio-serotypes and the pathogenicity markers of the analyzed isolates were determined. The experimental material comprised rectal swabs from 857 free-living animals hunter-harvested over a period of 2 years (2013-2014) in hunting districts across Poland. The isolates from bacteriological studies were confirmed by PCR and bio-serotyped based on the results of biochemical and agglutination tests. In the group of the 218 analyzed isolates of Y. enterocolitica, 133 were derived from wild boars, 70 from red deer, 11 from roe deer and 4 from fallow deer, and they accounted for 61.0%, 32.1%, 5.1% and 1.8% of all isolates, respectively. Bio-serotyping assays revealed that 91.7% of the examined isolates belonged to biotype 1A (200/218). The remaining 18 isolates belonged to bio-serotypes 1B/NI (3/218, 1.4%), 1B/O:8 (1/218, 0.5%), 2/NI (6/218, 2.8%), 2/O:27 (1/218, 0.5%), 2/O:3 (1/218, 0.5%), 2/O:9 (2/218, 0.9%), 3/NI (2/218, 0.9%), 4/O:3 (1/218, 0.5%) and 4/O:9 (1/218, 0.5%). The ail gene, a suggestive virulence gene for Y. enterocolitica, has been found in 30 isolates from 20 wild boars, in 6 isolates from red deer, and in 1 isolate from roe deer. Our study demonstrated that Y. enterocolitica is frequently isolated from game animals in Poland, which poses a risk of spreading these infectious agents to other animal species and humans. PMID- 29596491 TI - Core and skin temperature influences on the surface electromyographic responses to an isometric force and position task. AB - The large body of work demonstrating hyperthermic impairment of neuromuscular function has utilized maximal isometric contractions, but extrapolating these findings to whole-body exercise and submaximal, dynamic contractions may be problematic. We isolated and compared core and skin temperature influences on an isometric force task versus a position task requiring dynamic maintenance of joint angle. Surface electromyography (sEMG) was measured on the flexor carpi radialis at 60% of baseline maximal voluntary contraction while either pushing against a rigid restraint (force task) or while maintaining a constant wrist angle and supporting an equivalent inertial load (position task). Twenty participants performed each task at 0.5 degrees C rectal temperature (Tre) intervals while being passively heated from 37.1+/-0.3 degrees C to >=1.5 degrees C Tre and then cooled to 37.8+/-0.3 degrees C, permitting separate analyses of core versus skin temperature influences. During a 3-s contraction, trend analysis revealed a quadratic trend that peaked during hyperthermia for root-mean-square (RMS) amplitude during the force task. In contrast, RMS amplitude during the position task remained stable with passive heating, then rapidly increased with the initial decrease in skin temperature at the onset of passive cooling (p = 0.010). Combined hot core and hot skin elicited shifts toward higher frequencies in the sEMG signal during the force task (p = 0.003), whereas inconsistent changes in the frequency spectra occurred for the position task. Based on the patterns of RMS amplitude in response to thermal stress, we conclude that core temperature was the primary thermal afferent influencing neuromuscular response during a submaximal force task, with minimal input from skin temperature. However, skin temperature was the primary thermal afferent during a position task with minimal core temperature influence. Therefore, temperature has a task dependent impact on neuromuscular responses. PMID- 29596493 TI - Micronutrient adequacy is poor, but not associated with stunting between 12-24 months of age: A cohort study findings from a slum area of Bangladesh. AB - The prevalence of stunting among children below 5 years of age is higher in the slum-dwelling population of Bangladesh compared to that in both urban and rural areas. Studies have reported that several factors such as inadequate nutrition, low socio-economic status, poor hygiene and sanitation and lack of maternal education are the substantial predictors of childhood stunting. Almost all these factors are universally present in the slum-dwelling population of Bangladesh. However, few studies have prospectively examined such determinants of stunting among slum populations. In this paper, we reveal the findings of a cohort study with an aim to explore the status of micronutrient adequacy among such vulnerable children and establish its association with stunting along with other determinants. Two-hundred-sixty-five children were enrolled and followed since birth until 24 months of age. We collected anthropometric, morbidity and dietary intake data monthly. We used the 24-hour multiple-pass recall approach to collect dietary intake data from the age of 9 months onward. Micronutrient adequacy of the diet was determined by the mean adequacy ratio (MAR) which was constructed from the average intake of 9 vitamins and 4 minerals considered for the analysis. We used generalized estimating equation (GEE) regression models to establish the determinants of stunting between 12-24 months of age in our study population. The prevalence of low-birth-weight (LBW) was about 28.7% and approximately half of the children were stunted by the age of 24 months. The average micronutrient intake was considerably lower than the recommended dietary allowance and the MAR was only 0.48 at 24 months of age compared to the optimum value of 1. However, the MAR was not associated with stunting between 12-24 months of age. Rather, LBW was the significant determinant (AOR = 3.03, 95% CI: 1.69-5.44) after adjusting for other factors such as age (AOR = 2.12, 95% CI: 1.45-3.11 at 24 months and AOR = 1.97, 95% CI: 1.49-2.59 at 18 months, ref: 12 months) and sex (AOR = 1.98, 95% CI: 1.17-3.33, ref: female). Improving the nutritional quality of complementary food in terms of adequacy of micronutrients is imperative for optimum growth but may not be adequate to mitigate under-nutrition in this setting. Further research should focus on identifying multiple strategies that can work synergistically to diminish the burden of stunting in resource-poor settings. PMID- 29596494 TI - High rates of chronic HBV genotype E infection in a group of migrants in Italy from West Africa: Virological characteristics associated with poor immune clearance. AB - Hepatitis B virus (HBV) genotype E almost exclusively occurs in African people, and its presence is more commonly associated with the development of chronic HBV (CHB) infection. Moreover, an epidemiological link has been found between the distribution of HBV genotype E infection and African countries with high incidences of hepatocellular carcinoma. As part of a programme for the health assessment of migrants, we evaluated 358 young African subjects for HBV infection; 58.1% (208/358) were positive for an HBV marker, and 54 (25.5%) had CHB. Eighty-one percent of the CHB subjects were infected with HBV genotype E, with a median serum HBV-DNA of 3.2 (IQR: 2.7-3.6) logIU/ml. All patients had high serum HBsAg titres (10,899 [range 5,359-20,272] IU/ml), and no correlation was found between HBsAg titres and HBV-DNA plasma levels. RT sequence analysis showed the presence of a number of immune escape mutations: strains from all of the patients had a serine at HBsAg position 140; 3 also had T116N, Y100C, and P142L+S143L substitutions; and 1 had a G112R substitution. Six (18%) patients had stop-codons at position 216. In 5 of the 9 (26.5%) CHB patients, ultrasound liver biopsy, quantification of total intrahepatic HBV-DNA and cccDNA, and RT/HBsAg sequencing were performed. The median (IQR) total intrahepatic HBV-DNA was 766 (753-1139) copies/1000 cells, and the median (IQR) cccDNA was 17 (10-27) copies/1000 cells. Correlations were observed for both total intrahepatic HBV-DNA and cccDNA with serum HBV-DNA, while no correlation was found for the HBsAg titres. A difference of 2.5/1,000 nucleotides was found in the HBsAg sequences obtained from plasma and from liver tissue, with 3 cases of possible viral anatomical compartmentalization. In conclusion, a high rate of CHB infection due to the E genotype was demonstrated in a group of immigrants from Western Africa. An analysis of the viral strains obtained showed the virological characteristics of immune escape, which may be the cause of viral replication persistence. Moreover, a fair percentage of stop codon mutations were found. The lack of correlation between HBsAg titres and plasma or intrahepatic HBV-DNA found in these subjects suggests a pathway of virus production that is not linked to HBsAg secretion. Studies with a larger number of patients with CHB due to the E genotype are advisable to corroborate these observations. PMID- 29596496 TI - Radiogenomics analysis identifies correlations of digital mammography with clinical molecular signatures in breast cancer. AB - In breast cancer, well-known gene expression subtypes have been related to a specific clinical outcome. However, their impact on the breast tissue phenotype has been poorly studied. Here, we investigate the association of imaging data of tumors to gene expression signatures from 71 patients with breast cancer that underwent pre-treatment digital mammograms and tumor biopsies. From digital mammograms, a semi-automated radiogenomics analysis generated 1,078 features describing the shape, signal distribution, and texture of tumors along their contralateral image used as control. From tumor biopsy, we estimated the OncotypeDX and PAM50 recurrence scores using gene expression microarrays. Then, we used multivariate analysis under stringent cross-validation to train models predicting recurrence scores. Few univariate features reached Spearman correlation coefficients above 0.4. Nevertheless, multivariate analysis yielded significantly correlated models for both signatures (correlation of OncotypeDX = 0.49 +/- 0.07 and PAM50 = 0.32 +/- 0.10 in stringent cross-validation and OncotypeDX = 0.83 and PAM50 = 0.78 for a unique model). Equivalent models trained from the unaffected contralateral breast were not correlated suggesting that the image signatures were tumor-specific and that overfitting was not a considerable issue. We also noted that models were improved by combining clinical information (triple negative status and progesterone receptor). The models used mostly wavelets and fractal features suggesting their importance to capture tumor information. Our results suggest that molecular-based recurrence risk and breast cancer subtypes have observable radiographic phenotypes. To our knowledge, this is the first study associating mammographic information to gene expression recurrence signatures. PMID- 29596495 TI - Assessing the influence of health systems on Type 2 Diabetes Mellitus awareness, treatment, adherence, and control: A systematic review. AB - BACKGROUND: Type 2 Diabetes Mellitus (T2DM) is reported to affect one in 11 adults worldwide, with over 80% of T2DM patients residing in low-to-middle-income countries. Health systems play an integral role in responding to this increasing global prevalence, and are key to ensuring effective diabetes management. We conducted a systematic review to examine the health system-level factors influencing T2DM awareness, treatment, adherence, and control. METHODS AND FINDINGS: A protocol for this study was published on the PROSPERO international prospective register of systematic reviews (PROSPERO 2016: CRD42016048185). Studies included in this review reported the effects of health systems factors, interventions, policies, or programmes on T2DM control, awareness, treatment, and adherence. The following databases were searched on 22 February 2017: Medline, Embase, Global health, LILACS, Africa-Wide, IMSEAR, IMEMR, and WPRIM. There were no restrictions on date, language, or study designs. Two reviewers independently screened studies for eligibility, extracted the data, and screened for risk of bias. Thereafter, we performed a narrative synthesis. A meta-analysis was not conducted due to methodological heterogeneity across different aspects of included studies. 93 studies were included for qualitative synthesis; 7 were conducted in LMICs. Through this review, we found two key health system barriers to effective T2DM care and management: financial constraints faced by the patient and limited access to health services and medication. We also found three health system factors that facilitate effective T2DM care and management: the use of innovative care models, increased pharmacist involvement in care delivery, and education programmes led by healthcare professionals. CONCLUSIONS: This review points to the importance of reducing, or possibly eliminating, out-of-pocket costs for diabetes medication and self-monitoring supplies. It also points to the potential of adopting more innovative and integrated models of care, and the value of task-sharing of care with pharmacists. More studies which identify the effect of health system arrangements on various outcomes, particularly awareness, are needed. PMID- 29596497 TI - Social ecological factors and intimate partner violence in pregnancy. AB - BACKGROUND: Intimate partner violence (IPV) during pregnancy increases adverse pregnancy outcomes. Knowledge of societal, community, family and individual related factors associated with IPV in pregnancy is limited in Ethiopia. Our study examined these factors in an Ethiopian context. MATERIALS AND METHODS: A cross sectional study was conducted among pregnant women attending antenatal care at governmental health institutions, using a consecutive probability sampling strategy. A total of 720 pregnant women were interviewed by five trained nurses or midwives, using a standardized and /pretested survey questionnaire. Bivariate and multivariate logistic regression analyses were applied to assess factors contributing to IPV. We used Akaike's information criteria, to identify the model that best describes the factors influencing IPV in pregnancy. RESULTS: Among the women interviewed, physical IPV was reported by 35.6%, and lifetime emotional or physical abuse by 81.0%. Perceiving violence as a means to settle interpersonal conflicts, presence of supportive attitudes of wife beating in the society, regarding violence as an expression of masculinity, and presence of strict gender role differences in the society, were all positively associated to IPV in pregnancy. The presence of groups legitimizing men's violence in the community, feeling isolated, having no social support for victims, and presence of high unemployment, were the perceived community related factors positively associated with IPV in pregnancy. CONCLUSION: IPV in pregnancy is very prevalent in Ethiopia and is associated with multiple social ecologic factors. Reduction of IPV in pregnancy calls for cross sectorial efforts from stakeholders at different levels.

AB - BACKGROUND: Benign ethnic neutropenia (BEN) is a hematologic condition associated with people of African ancestry and specific Middle Eastern ethnic groups. Prior genetic association studies in large population showed that rs2814778 in Duffy Antigen Receptor for Chemokines (DARC) gene, specifically DARC null red cell phenotype, was associated with BEN. However, the mechanism of this red cell phenotype leading to low white cell count remained elusive. METHODS: We conducted an extreme phenotype design genome-wide association study (GWAS), analyzed ~16 million single nucleotide polymorphisms (SNP) in 1,178 African-Americans individuals from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study and replicated from 819 African-American participants in the Atherosclerosis Risk in Communities (ARIC) study. Conditional analyses on rs2814778 were performed to identify additional association signals on chromosome 1q22. In a separate cohort of healthy individuals with and without BEN, whole genome gene expression from peripheral blood neutrophils were analyzed for DARC. RESULTS: We confirmed that rs2814778 in DARC was associated with BEN (p = 4.09*10 53). Conditioning on rs2814778 abolished other significant chromosome 1 associations. Inflammatory cytokines (IL-2, 6, and 10) in participants in the Howard University Family Study (HUFS) and Multi-Ethnic Study in Atherosclerosis (MESA) showed similar levels in individuals homozygous for the rs2814778 allele compared to others, indicating cytokine sink hypothesis played a minor role in leukocyte homeostasis. Gene expression in neutrophils of individuals with and without BEN was also similar except for low DARC expression in BEN, suggesting normal function. BEN neutrophils had slightly activated profiles in leukocyte migration and hematopoietic stem cell mobilization pathways (expression fold change <2). CONCLUSIONS: These results in humans support the notion of DARC null erythroid progenitors preferentially differentiating to myeloid cells, leading to activated DARC null neutrophils egressing from circulation to the spleen, and causing relative neutropenia. Collectively, these human data sufficiently explained the mechanism DARC null red cell phenotype causing BEN and further provided a biologic basis that BEN is clinically benign. PMID- 29596499 TI - Specific protein carbonylation in human breast cancer tissue compared to adjacent healthy epithelial tissue. AB - Protein carbonylation is an irreversible post-translational modification induced by severe oxidative stress. Reactive oxygen species (ROS) are constantly produced in cells and play important roles in both cancer progression and cancer suppression. ROS levels can be higher in tumor compared to surrounding healthy tissue but ROS-induced specific protein carbonylation and its unique role in cancer progression or suppression is poorly understood. In this study, we utilized previously validated ELISA and western blot methods to analyze the total and specific protein carbonylation in flash-frozen human breast cancer and matched adjacent healthy tissue to compare relative total, and specific protein carbonylation. Mass spectrometry, two-color western, and immunoprecipitation methods were used to identify and confirm the specifically carbonylated proteins in breast tumor tissue. Superoxide dismutase (SOD) activity was measured as an indicator of antioxidant activity, and LC3-II protein level was analyzed for autophagy by western blot. Findings were further confirmed using the immortalized MDA-MB-231 and MDA-MB-468 breast cancer and MCF-12A noncancerous human epithelial breast cell lines. Our results indicate that tumor tissue has greater total protein carbonylation, lower SOD1 and SOD2 protein levels, lower total SOD activity, and higher LC3-II levels compared to adjacent healthy tissue. We identified and confirmed three specific proteins of interest; filamin A, heat shock protein 90beta (HSP90beta), and bifunctional glutamate/proline-tRNA ligase (EPRS), that were selectively carbonylated in tumor tissue compared to matched adjacent healthy tissue. Correspondingly, compared to noncancerous MCF-12A epithelial cells, MDA-MB-231 cancer cells exhibited an increase in filamin A and EPRS protein carbonylation, decreased total SOD activity, and increased autophagy, but not increased HSP90beta protein carbonylation. Identification of selectively carbonylated proteins and defining their roles in cancer progression may promote the development of targeted therapeutic approaches toward mitigating oxidative damage of these proteins.

AB - To grow straight and upright, plants need to regulate actively their posture. Gravitropic movement, which occurs when plants modify their growth and curvature to orient their aerial organ against the force of gravity, is a major feature of this postural control. A recent model has shown that graviception and proprioception are sufficient to account for the gravitropic movement and subsequent organ posture demonstrated by a range of species. However, some plants, including wheat coleoptiles, exhibit a stronger regulation of posture than predicted by the model. Here, we performed an extensive kinematics study on wheat coleoptiles during a gravitropic perturbation (tilting) experiment in order to better understand this unexpectedly strong regulation. Close temporal observations of the data revealed that both perturbed and unperturbed coleoptiles showed oscillatory pulses of elongation and curvature variation that propagated from the apex to the base of their aerial organs. In perturbed coleoptiles, we discovered a non-trivial coupling between the oscillatory dynamics of curvature and elongation. The relationship between those oscillations and the postural control of the organ remains unclear, but indicates the presence of a mechanism that is capable of affecting the relationship between elongation rate, differential growth, and curvature. PMID- 29596501 TI - Are diverse societies less cohesive? Testing contact and mediated contact theories. AB - Previous research has demonstrated that there is a negative relationship between ethnic diversity in a local community and social cohesion. Often the way social cohesion is assessed, though, varies across studies and only some aspects of the construct are included (e.g., trust). The current research explores the relationship between diversity and social cohesion across a number of indicators of social cohesion including neighbourhood social capital, safety, belonging, generalized trust, and volunteering. Furthermore, social psychological theories concerning the role of positive contact and its impact on feelings of threat are investigated. Using a sample of 1070 third generation 'majority' Australians and structural equation modelling (SEM), findings suggest ethnic diversity is related to positive intergroup contact, and that contact showed beneficial impacts for some indicators of social cohesion both directly and indirectly through reducing perceived threat. When interethnic contact and perceived threat are included in the model there is no direct negative effect between diversity and social cohesion. The theoretical implications of these findings are outlined including the importance of facilitating opportunities for positive contact in diverse communities.

PMID- 29596503 TI - Empirical radio propagation model for DTV applied to non-homogeneous paths and different climates using machine learning techniques. AB - The establishment and improvement of transmission systems rely on models that take into account, (among other factors), the geographical features of the region, as these can lead to signal degradation. This is particularly important in Brazil, where there is a great diversity of scenery and climates. This article proposes an outdoor empirical radio propagation model for Ultra High Frequency (UHF) band, that estimates received power values that can be applied to non homogeneous paths and different climates, this last being of an innovative character for the UHF band. Different artificial intelligence techniques were chosen on a theoretical and computational basis and made it possible to introduce, organize and describe quantitative and qualitative data quickly and efficiently, and thus determine the received power in a wide range of settings and climates. The proposed model was applied to a city in the Amazon region with heterogeneous paths, wooded urban areas and fractions of freshwater among other factors. Measurement campaigns were conducted to obtain data signals from two digital TV stations in the metropolitan area of the city of Belem, in the State of Para, to design, compare and validate the model. The results are consistent since the model shows a clear difference between the two seasons of the studied year and small RMS errors in all the cases studied. PMID- 29596504 TI - Influences of Native American land use on the Colonial Euro-American settlement of the South Carolina Piedmont. AB - We test the hypothesis that prehistoric Native American land use influenced the Euro-American settlement process in a South Carolina Piedmont landscape. Long term ecological studies demonstrate that land use legacies influence processes and trajectories in complex, coupled social and ecological systems. Native American land use likely altered the ecological and evolutionary feedback and trajectories of many North American landscapes. Yet, considerable debate revolves around the scale and extent of land use legacies of prehistoric Native Americans. At the core of this debate is the question of whether or not European colonists settled a mostly "wild" landscape or an already "humanized" landscape. We use statistical event analysis to model the effects of prehistoric Native American settlement on the rate of Colonial land grants (1749-1775). Our results reveal how abandoned Native American settlements were among the first areas claimed and homesteaded by Euro-Americans. We suggest that prehistoric land use legacies served as key focal nodes in the Colonial era settlement process. As a consequence, localized prehistoric land use legacies likely helped structure the long term, landscape- to regional-level ecological inheritances that resulted from Euro-American settlement.

PMID- 29596505 TI - Childhood behavioral inhibition is associated with impaired mentalizing in adolescence. AB - Recent advances suggest that impairment in social cognition (SC) may play a role in the development of social anxiety (SA). However, very few studies have analyzed whether SA fosters poorer social-cognitive development as it leads to social avoidance. This study aimed to analyze whether retrospectively assessed behavioral inhibition (BI) (i.e., an early form of SA) in childhood is associated with a deficit in social cognition operationalized as impairment of mentalizing (MZ) in adolescence. A sample of 256 adolescents (range: 12-18 years; mean age: 14.7 years; SD = 1.7) from general population were assessed for MZ capacities and retrospective BI through self-report and interview measures. Results comparing three groups of adolescents with different levels of childhood BI (low, moderate or high) and controlling for concurrent SA and depression reveal that the higher the level of BI, the lower the level of MZ. These results were consistent for almost all mentalization measures, including when both extreme (i.e., high vs. low BI) and non-extreme (i.e., high vs. moderate BI) were compared in both self report and interview measures and in both dimensions of MZ (i.e., MZ referred to others' and to own mental states). These findings support that childhood forms of SA are associated to deficit in SC in adolescence. A possible bi-directional relationship between SA and SC, and the role that it may play in the pathway to clinical SA are discussed. PMID- 29596507 TI - Comparison of the immune response during acute and chronic Staphylococcus aureus infection. AB - Staphylococcus aureus bacteria are able to grow in a planktonic state that is associated with acute infections and in biofilms that are associated with chronic infections. Acute infections, such as skin infections, are often self-limiting. However, chronic infections, such as implant infections, can be difficult to clear and may require surgical intervention. The host immune response may contribute to the different outcomes often associated with these two disease types. We used proteomic arrays and two murine models for an initial, descriptive characterization of the contribution of the host immune response to outcomes of acute versus chronic S. aureus disease. We compared the immune responses between a model of self-limiting skin and soft tissue infection caused by the planktonic form of S. aureus versus a model of surgical mesh implant infection, which we show to be caused by a bacterial biofilm. The significantly altered host cytokines and chemokines were largely different in the two models, with responses diminished by 21 days post-implantation in surgical mesh infection. Because bacterial levels remained constant during the 21 days that the surgical mesh infection was followed, those cytokines that are significantly increased during chronic infection are not likely effective in eradicating biofilm. Comparison of the levels of cytokines and chemokines in acute versus chronic S. aureus infection can provide a starting point for evaluation of the role of specific immune factors that are present in one disease manifestation but not the other.

AB - Deformed wing virus (DWV) is an important pathogen in a broad range of insects, including honey bees. Concordant with the spread of Varroa, DWV is present in the majority of honey bee colonies and can result in either low-level infections with asymptomatic bees that nonetheless exhibit increased colony loss under stress, or high-level infections with acute effects on bee health and viability. DWV can be transmitted vertically or horizontally and evidence suggests that horizontal transmission via Varroa is associated with acute symptomatic infections. Vertical transmission also occurs and is presumably important for the maintenance of DWV in honey bee populations. To further our understanding the vertical transmission of DWV through queens, we performed three experiments: we studied the quantitative effectiveness of vertical transmission, surveyed the prevalence of successful egg infection under commercial conditions, and distinguished among three possible mechanisms of transmission. We find that queen-infection level predicts the DWV titers in their eggs, although the transmission is not very efficient. Our quantitative assessment of DWV demonstrates that eggs in 1/3 of the colonies are infected with DWV and highly infected eggs are rare in newly installed spring colonies. Additionally, our results indicate that DWV transmission occurs predominantly by virus adhering to the surface of eggs (transovum) rather than intracellularly. Our combined results suggest that the queens' DWV vectoring capacity in practice is not as high as its theoretical potential. Thus, DWV transmission by honey bee queens is part of the DWV epidemic with relevant practical implications, which should be further studied.

AB - BACKGROUND: Polypharmacy is common among older adults. However, little is known about the composition of polypharmacy: which are the most frequently used drugs, and how much do these drugs contribute to the overall prevalence of polypharmacy. METHODS: A total of 822,619 Swedes aged >=75 years was identified from the Total Population Register. Through record-linkage with the Swedish Prescribed Drug Register and the Social Services Register we could analyze concurrent drug use in the entire population (both individuals living in the community and institution) on the 31 December 2013. RESULTS: The prevalence of polypharmacy (>=5 drugs) was 45%. The most frequently used drugs were cardiovascular drugs, analgesics, and psychotropics. By excluding the ten most frequently used drug classes or compounds, the prevalence of polypharmacy was reduced by 69% and 51% respectively. The majority of the users of either one of the 10 most frequently used drugs concurrently used at least 4 other drug classes (66%-85%). CONCLUSION: Almost half of the individuals aged >=75 years are exposed to polypharmacy in Sweden. A handful of drugs make a large contribution to the overall prevalence of polypharmacy and the majority of drugs prescribed to persons aged >=75 years are used in combination with other drugs. This highlights the high use of drugs, and the need to consider other concurrent drug treatments when prescribing for older adults. PMID- 29596513 TI - Bad manners in the Emergency Department: Incivility among doctors. AB - INTRODUCTION: Negative workplace behaviour, especially negative communication is a recognised problem in many organisations and is known to have serious impact on workplace performance, productivity and personal wellbeing. Emergency Departments (ED) can be high stress environments in which communication and perceptions of respect between physicians and other staff may underlie individual functioning. We conducted a study to estimate the influence of incivility (ICV) among physicians in the ED. METHODS: We developed an online survey to assess workplace incivility in the ED. We focussed on frequency, origin, reasons and situations where ICV was reported. To measure the levels and the potential influence of ICV on psychological safety, social stress and personal wellbeing we correlated our questionnaire to standard psychological scales. Statistical analysis included Students t-test, chi squared distribution and Pearson correlation coefficient. RESULTS: We invited all seventy-seven ED physicians to participate in our survey. Among those that completed (n = 50, 65%) the survey, 9% of ED physicians reported frequent (1/week) and 38% occasional (1/month) incidents of ICV. 28% of physicians reported experiencing ICV once per quarter and 21% reported a frequency of only once per year, no physician reported ICV on a daily basis. Levels of ICV were significantly higher in interactions with specialists from outside then within the ED (p<0.01). ICV was perceived particularly during critical situations. Our findings showed a significant correlation between internal (within the ED team) ICV and psychological safety. To ED physicians internal ICV was associated with lower levels of psychological safety (p<0.01). ICV displayed from sources outside the ED team was not associated with psychological safety, but we found a significant influence of external ICV on personal irritability and reduced wellbeing (p<0.01). DISCUSSION: The incidence of incivility was high among the ED physicians. Although this was a small sample, the association between workplace ICV and psychological safety, personal irritation as well personal comfort suggests that ICV may be an important variable underlying ED team performance. These findings further underscore the need to foster a culture of respect and good communication between departments, as levels of ICV were highest with physicians from outside the ED. Future research would benefit from examining strategies to prevent and reduce ICV and identify reasons for personal variation in perception of ICV. During critical situations and in general collaboration with specialists, awareness of ICV and countermeasures are important to avoid decreased performance and negative impact on staff and patient. PMID- 29596514 TI - Characterisation of insulin analogues therapeutically available to patients. AB - The structure and function of clinical dosage insulin and its analogues were assessed. This included 'native insulins' (human recombinant, bovine, porcine), 'fast-acting analogues' (aspart, glulisine, lispro) and 'slow-acting analogues' (glargine, detemir, degludec). Analytical ultracentrifugation, both sedimentation velocity and equilibrium experiments, were employed to yield distributions of both molar mass and sedimentation coefficient of all nine insulins. Size exclusion chromatography, coupled to multi-angle light scattering, was also used to explore the function of these analogues. On ultracentrifugation analysis, the insulins under investigation were found to be in numerous conformational states, however the majority of insulins were present in a primarily hexameric conformation. This was true for all native insulins and two fast-acting analogues. However, glargine was present as a dimer, detemir was a multi hexameric system, degludec was a dodecamer (di-hexamer) and glulisine was present as a dimer-hexamer-dihexamer system. However, size-exclusion chromatography showed that the two hexameric fast-acting analogues (aspart and lispro) dissociated into monomers and dimers due to the lack of zinc in the mobile phase. This comprehensive study is the first time all nine insulins have been characterised in this way, the first time that insulin detemir have been studied using analytical ultracentrifugation and the first time that insulins aspart and glulisine have been studied using sedimentation equilibrium. The structure and function of these clinically administered insulins is of critical importance and this research adds novel data to an otherwise complex functional physiological protein.

AB - This national online cross-sectional survey in Italy assessed primary care pediatricians' (PCPs) attitudes and practices regarding Human papillomavirus (HPV) vaccination and the contribution of several characteristics. The questionnaire was distributed from September 2016 to June 2017 to a random sample of 640 PCPs by email via an internet-link leading to a web-based survey platform (Lime Survey). Only 18.4% of PCPs always recommend the HPV vaccine to 11-12 year old boys. PCPs with longer practice activity, working in solo practice, always recommended the HPV vaccine to 11-12 year old girls, and believed that the vaccine was effective for boys were more likely to always recommend the HPV vaccine. PCPs working in a Region where the vaccination was actively recommended and provided free of charge to 11-12 year old boys had higher odds of recommending vaccination. More than two thirds of PCPs (77.4%) always recommend the HPV vaccine to 11-12 year old girls. PCPs who believed that the vaccine was effective for girls and safe in both boys and girls, who always talk with patients of 11-18 years or their parents about HPV infection and vaccination, and who obtain vaccine information from scientific journals were more likely to always recommend the vaccine. PCPs should employ evidence-based educational strategies in order to achieve a better coverage and to reduce the morbidities and mortality of diseases associated with HPV. PMID- 29596516 TI - Age-specific characterization of spinal cord injuries over a 19-year period at a Japanese rehabilitation center. AB - Regional demographics of spinal cord injuries (SCIs) are fundamental to identifying and implementing appropriate preventive measures. The current study was conducted as a longitudinal analysis of all patients with SCIs admitted to the Hyogo Rehabilitation Center over a 19-year period. The sex and age of the patient, time and nature of injury (i.e., cause, level, and extent), and period from injury to admission were evaluated retrospectively. Pertinent tests, including Poisson regression analysis, and the Cochran-Armitage, Kruskal-Wallis, and chi-square tests, were applied to assess demographic variables, with statistical significance set at p < 0.05. Between 1995 and 2013, a total of 632 patients with SCIs (predominantly male and largely < 60 years old) were admitted to our center for rehabilitation. Although the male: female ratio remained unchanged throughout the study period, the ratio of older adults increased over time. In assessing the cause of injury, the majority of the patients involved in road traffic accidents were aged <= 44 years, whereas patients aged >= 45 years accounted for the majority of low-distance falls and disease-related SCIs, the proportions of which gradually increased. Complete paralysis and paraplegia primarily occurred in patients aged <= 44 years, whereas the majority of incomplete injuries and tetraplegia were limited to those aged >= 45 years. The patient age at the time of SCI and the nature of the injury sustained were interrelated. Age-specific strategies thus offered the best means of preventing/reducing the incidence of SCIs in Hyogo prefecture.

AB - In recent years, entrepreneurship has been gaining more prominence as a potential tool for solving poverty in developing countries. This paper mainly examines the relationship between farmer entrepreneurship and rural poverty alleviation in China by assessing the contribution of farm entrepreneurs towards overcoming poverty. Data were collected from 309 employees of farmer entrepreneurships in Guangxi Province through survey questionnaires. Structural equation modeling was used to conduct an analysis of the effects of three identified capabilities of farm entrepreneurs-economic, educational and knowledge, and socio-cultural capabilities-on attitude towards farmer entrepreneurship growth and the qualitative growth of farmer entrepreneurship and how these in turn affect rural poverty, using AMOS 21. The findings show that socio-cultural capability has the greatest influence on farmer entrepreneurship growth (beta = 0.50, p<0.001). The qualitative growth of farmer entrepreneurship also more significantly impacts rural poverty (beta = 0.69, p<0.001) than attitude towards farmer entrepreneurship growth. This study suggests that policy makers in China should involve more rural farmers in the targeted poverty alleviation strategies of the government by equipping rural farmers with entrepreneurial skills. This can serve as a sustainable, bottom-up approach to alleviating rural poverty in remote areas of the country. The study also extends the literature on the farmer entrepreneurship-rural poverty alleviation nexus in China, and this can serve as a lesson for other developing countries in the fight against rural poverty.

AB - Here we demonstrate the application of a method that could accelerate the development of novel therapies by allowing direct and repeatable visualization of cellular function in the living eye, to study loss of vision in animal models of retinal disease, as well as evaluate the time course of retinal function following therapeutic intervention. We use high-resolution adaptive optics scanning light ophthalmoscopy to image fluorescence from the calcium sensor GCaMP6s. In mice with photoreceptor degeneration (rd10), we measured restored visual responses in ganglion cell layer neurons expressing the red-shifted channelrhodopsin ChrimsonR over a six-week period following significant loss of visual responses. Combining a fluorescent calcium sensor, a channelrhodopsin, and adaptive optics enables all-optical stimulation and recording of retinal neurons in the living eye. Because the retina is an accessible portal to the central nervous system, our method also provides a novel non-invasive method of dissecting neuronal processing in the brain.

AB - Amnion is a membrane surrounding the embryo/fetus which determine growth factors and interleukins with angiogenic, immunogenic, and anti-inflammatory properties. The aim of the present study was to investigate the effects of conditioned culture medium from 24-h cultures of human amnion (hAM CCM) on migration and proliferation of human umbilical vein endothelial primary cells (HUVECs), freshly isolated bone marrow mononuclear cells (BM MNCs), and Jurkat leukemia cell line. Amnion membrane was freshly isolated from healthy placenta and its fragments cultured in vitro to produce hAM CCM. Members of the IGFBP protein family made up one third of all assayed proteins present in the hAM medium. The hAM CCM did not affect the proliferation rate of HUVECs or MNCs, but we observed more intensive migration of those cells, and lower expression of CD31 surface antigen on HUVECs as compared to control cultures. In contrast, Jurkat cells did not respond to hAM CCM treatment by proliferation or mobility change. The conditioned medium from 24 h cultures of human amnion is easy to obtain and is a convenient source of various growth and other factors that may be useful in practical medicine. PMID- 29596520 TI - Carcinoma associated fibroblasts (CAFs) promote breast cancer motility by suppressing mammalian Diaphanous-related formin-2 (mDia2). AB - The tumor microenvironment (TME) promotes tumor cell invasion and metastasis. An important step in the shift to a pro-cancerous microenvironment is the transformation of normal stromal fibroblasts to carcinoma-associated fibroblasts (CAFs). CAFs are present in a majority of solid tumors and can directly promote tumor cell motility via cytokine, chemokine and growth factor secretion into the TME. The exact effects that the TME has upon cytoskeletal regulation in motile tumor cells remain enigmatic. The conserved formin family of cytoskeleton regulating proteins plays an essential role in the assembly and/or bundling of unbranched actin filaments. Mammalian Diaphanous-related formin 2 (mDia2/DIAPH3/Drf3/Dia) assembles a dynamic F-actin cytoskeleton that underlies tumor cell migration and invasion. We therefore sought to understand whether CAF derived chemokines impact breast tumor cell motility through modification of the formin-assembled F-actin cytoskeleton. In MDA-MB-231 cells, conditioned media (CM) from WS19T CAFs, a human breast tumor-adjacent CAF line, significantly and robustly increased wound closure and invasion relative to normal human mammary fibroblast (HMF)-CM. WS19T-CM also promoted proteasome-mediated mDia2 degradation in MDA-MB-231 cells relative to control HMF-CM and WS21T CAF-CM, a breast CAF cell line that failed to promote robust MDA-MB-231 migration. Cytokine array analysis of CM identified up-regulated secreted factors in WS19T relative to control WS21T CM. We identified CXCL12 as a CM factor influencing loss of mDia2 protein while increasing MDA-MB-231 cell migration. Our data suggest a mechanism whereby CAFs promote tumor cell migration and invasion through CXCL12 secretion to regulate the mDia2-directed cytoskeleton in breast tumor cells.

AB - BACKGROUND: Despite the number of studies that have tried to demonstrate that there is an association between previous falls and the fear of falling, the relationship between these two variables remains a matter of controversy. OBJECTIVES: Our objective was to investigate whether the fear of falling is a cause of falls, a consequence, or both in community-dwelling adults aged >= 75 years old. METHODS: A descriptive, longitudinal, prospective study was performed. A total of 640 individuals were interviewed between 2009 and 2011. Sociodemographic data, health status, history of falls and fear of falling were assessed at baseline and at 24 months. RESULTS: The prevalence of falls at baseline was 25% as opposed to 35.2% at 24 months. The prevalence of the fear of falling was 41.5% at baseline. Logistic regression analysis showed a significant association between a history of falls and the fear of falling. Other factors associated with the fear of falling were female gender, comorbidity, depressive symptoms, and disability. In total, 41.7% of the subjects who had reported a fear of falling at baseline had suffered at least one fall 24 months later. Unadjusted Cox regression analysis revealed that the fear of falling was a risk factor for falls. According to the final model adjusted for other covariates, the only reliable predictor was female gender. The Cox model stratified by gender failed to show a crude association between fear of falling and falls. CONCLUSION: A previous history of falls in the previous year was a good predictor of the fear of falling; but the fear of falling was a predictor of falls during follow-up only in the unadjusted model, pointing to strong gender turns out as an effect modifier of the association of FOF and subsequent falls. Nursing staff working in elderly care should not only routinely assess patients' previous history of falls, but also evaluate their fear of falling and its associated factors.

AB - PURPOSE: To retrospectively investigate whether texture features obtained from preoperative CT images of advanced gastric cancer (AGC) patients could be used for the prediction of occult peritoneal carcinomatosis (PC) detected during operation. MATERIALS AND METHODS: 51 AGC patients with occult PC detected during operation from January 2009 to December 2012 were included as occult PC group. For the control group, other 51 AGC patients without evidence of distant metastasis including PC, and whose clinical T and N stage could be matched to those of the patients of the occult PC group, were selected from the period of January 2011 to July 2012. Each group was divided into test (n = 41) and validation cohort (n = 10). Demographic and clinical data of these patients were acquired from the hospital database. Texture features including average, standard deviation, kurtosis, skewness, entropy, correlation, and contrast were obtained from manually drawn region of interest (ROI) over the omentum on the axial CT image showing the omentum at its largest cross sectional area. After using Fisher's exact and Wilcoxon signed-rank test for comparison of the clinical and texture features between the two groups of the test cohort, conditional logistic regression analysis was performed to determine significant independent predictor for occult PC. Using the optimal cut-off value from receiver operating characteristic (ROC) analysis for the significant variables, diagnostic sensitivity and specificity were determined in the test cohort. The cut-off value of the significant variables obtained from the test cohort was then applied to the validation cohort. Bonferroni correction was used to adjust P value for multiple comparisons. RESULTS: Between the two groups, there was no significant difference in the clinical features. Regarding the texture features, the occult PC group showed significantly higher average, entropy, standard deviation, and significantly lower correlation (P value < 0.004 for all). Conditional logistic regression analysis demonstrated that entropy was significant independent predictor for occult PC. When the cut-off value of entropy (> 7.141) was applied to the validation cohort, sensitivity and specificity for the prediction of occult PC were 80% and 90%, respectively. CONCLUSION: For AGC patients whose PC cannot be detected with routine imaging such as CT, texture analysis may be a useful adjunct for the prediction of occult PC.

AB - The current work examined the unique contribution that autistic traits and social anxiety have on tasks examining attention and emotion processing. In Study 1, 119 typically-developing college students completed a flanker task assessing the control of attention to target faces and away from distracting faces during emotion identification. In Study 2, 208 typically-developing college students performed a visual search task which required identification of whether a series of 8 or 16 emotional faces depicted the same or different emotions. Participants with more self-reported autistic traits performed more slowly on the flanker task in Study 1 than those with fewer autistic traits when stimuli depicted complex emotions. In Study 2, participants higher in social anxiety performed less accurately on trials showing all complex faces; participants with autistic traits showed no differences. These studies suggest that traits related to autism and to social anxiety differentially impact social cognitive processing.

PMID- 29596524 TI - Effects of repetitive transcranial magnetic stimulation and trans-spinal direct current stimulation associated with treadmill exercise in spinal cord and cortical excitability of healthy subjects: A triple-blind, randomized and sham controlled study. AB - Repetitive transcranial magnetic stimulation (rTMS) over motor cortex and trans spinal direct current stimulation (tsDCS) modulate corticospinal circuits in healthy and injured subjects. However, their associated effects with physical exercise is still not defined. This study aimed to investigate the effect of three different settings of rTMS and tsDCS combined with treadmill exercise on spinal cord and cortical excitability of healthy subjects. We performed a triple blind, randomized, sham-controlled crossover study with 12 healthy volunteers who underwent single sessions of rTMS (1Hz, 20Hz and Sham) and tsDCS (anodal, cathodal and Sham) associated with 20 minutes of treadmill walking. Cortical excitability was assessed by motor evoked potential (MEP) and spinal cord excitability by the Hoffmann reflex (Hr), nociceptive flexion reflex (NFR) and homosynaptic depression (HD). All measures were assessed before, immediately, 30 and 60 minutes after the experimental procedures. Our results demonstrated that anodal tsDCS/treadmill exercise reduced MEP's amplitude and NFR's area compared to sham condition, conversely, cathodal tsDCS/treadmill exercise increased NFR's area. High-frequency rTMS increased MEP's amplitude and NFR's area compared to sham condition. Anodal tsDCS/treadmill exercise and 20Hz rTMS/treadmill exercise reduced Hr amplitude up to 30 minutes after stimulation offset and no changes were observed in HD measures. We demonstrated that tsDCS and rTMS combined with treadmill exercise modulated cortical and spinal cord excitability through different mechanisms. tsDCS modulated spinal reflexes in a polarity-dependent way acting at local spinal circuits while rTMS probably promoted changes in the presynaptic inhibition of spinal motoneurons. In addition, the association of two neuromodulatory techniques induced long-lasting changes. PMID- 29596526 TI - ABO blood groups as a prognostic factor for recurrence in ovarian and vulvar cancer. AB - The relationship between ABO blood groups (BG) and risk of incidence in cancers including gynecological cancers has been widely studied, showing increased incidence risk for BG A patients. As available data are inconsistent we investigated whether BG and their anti-glycan antibodies (anti-A and anti-B) have prognostic values in gynecological cancers. We retrospectively evaluated 974 patients with gynecological cancers in three cancer centers (Switzerland and Australia) between 1974 and 2014 regarding the relationships between clinico pathological findings and the BG. Time to disease recurrence was significantly influenced by BG in patients with ovarian (n = 282) and vulvar (n = 67) cancer. BG O or B patients showed a significantly increased risk for ovarian cancer relapse compared to A, 59% and 82%, respectively (p = 0.045; HR O vs A = 1.59 (CI 1.01-2.51) and (p = 0.036; HR A vs B = 0.55 (CI 0.32-0.96). Median time to relapse for advanced stage (n = 126) ovarian cancer patients was 18.2 months for BG O and 32.2 for A (p = 0.031; HR O vs A = 2.07 (CI 1.07-4.02)). BG also significantly influenced relapse-free survival in patients with vulvar cancer (p = 0.002), with BG O tending to have increased relapse risk compared to A (p = 0.089). Blood groups hence associate with recurrence in ovarian and vulvar cancer: women with BG O seem to have a lower ovarian cancer incidence, however are more likely to relapse earlier. The significance of the BG status as a prognostic value is evident and may be helpful to oncologists in prognosticating disease outcome and selecting the appropriate therapy.

AB - BACKGROUND: Influenza is an important cause of acute lower respiratory tract infection (aLRTI), hospitalization, and mortality in children. This study aimed to describe the clinical and epidemiologic patterns and infection factors associated with influenza, and compare case features of influenza A and B. METHODS: In a prospective, cross-sectional study, patients admitted for aLRTI, between 2000 and 2015, were tested for respiratory syncytial virus, adenovirus, influenza, or parainfluenza, and confirmed by fluorescent antibody (FA) or real time polymerase chain reaction (RT-PCR) assay of nasopharyngeal aspirates. RESULTS: Of 14,044 patients, 37.7% (5290) had FA- or RT-PCR-confirmed samples that identified influenza in 2.8% (394/14,044; 91.4% [360] influenza A, 8.6% [34] influenza B) of cases. Influenza frequency followed a seasonal epidemic pattern (May-July, the lowest average temperature months). The median age of cases was 12 months (interquartile range: 6-21 months); 56.1% (221/394) of cases were male. Consolidated pneumonia was the most frequent clinical presentation (56.9%; 224/394). Roughly half (49.7%; 196/394) of all cases had previous respiratory admissions; 9.4% (37/394) were re-admissions; 61.5% (241/392) had comorbidities; 26.2% (102/389) had complications; 7.8% (30/384) had nosocomial infections. The average case fatality rate was 2.1% (8/389). Chronic neurologic disease was significantly higher in influenza B cases compared to influenza A cases (p = 0.030). The independent predictors for influenza were: age >=6 months, odds ratio (OR): 1.88 (95% confidence interval [CI]: 1.44-2.45); p<0.001; presence of chronic neurologic disease, OR: 1.48 (95% CI: 1.01-2.17); p = 0.041; previous respiratory admissions, OR: 1.71 (95% CI: 1.36-2.14); p<0.001; re-admissions, OR: 1.71 (95% CI: 1.17-2.51); p = 0.006; clinical pneumonia, OR: 1.50 (95% CI: 1.21 1.87); p<0.001; immunodeficiency, OR: 1.87 (95% CI: 1.15-3.05); p = 0.011; cystic fibrosis, OR: 4.42 (95% CI: 1.29-15.14); p = 0.018. CONCLUSION: Influenza showed an epidemic seasonal pattern (May-July), with higher risk in children >=6 months, or with pneumonia, previous respiratory admissions, or certain comorbidities. PMID- 29596528 TI - Apaf1 plays a negative regulatory role in T cell responses by suppressing activation of antigen-stimulated T cells. AB - Apaf1 is a critical component of the apoptosome and initiates apoptosis downstream mitochondrial damages. Although the importance of Apaf1 in embryonic development was shown, the role of Apaf1 in immune responses, especially T cell responses, has yet to be elucidated. We generated T cell-specific Apaf1-deficient mice (Lck-Cre-Apaf1f/f mice) and examined the antigen-specific delayed-type hypersensitivity (DTH). Lck-Cre-Apaf1f/f mice exhibited exacerbation of DTH responses as compared with Apaf1-sufficient control mice. In Lck-Cre-Apaf1f/f mice, antigen-specific T cells proliferated more, and produced more inflammatory cytokines than control T cells. Apaf1-deficient T cells from antigen-immunized mice showed higher percentages of activation phenotypes upon restimulation in vitro. Apaf1-deficient T cells from naive (non-immunized) mice also showed higher proliferation activity and cytokine production over control cells. The impact of Apaf1-deficiency in T cells, however, was not restored by a pan-caspase inhibitor, suggesting that the role of Apaf1 in T cell responses was caspase independent/non-apoptotic. These data collectively demonstrated that Apaf1 is a negative regulator of T cell responses and implicated Apaf1 as a potential target for immunosuppressive drug discovery. PMID- 29596530 TI - Establishment and characterization of pygmy killer whale (Feresa attenuata) dermal fibroblast cell line. AB - The pygmy killer whale (Feresa attenuata) (PKW) is a tropical and subtropical marine mammal commonly found in the Atlantic, Indian and Pacific oceans. Since the PKWs live in offshore protected territories, they are rarely seen onshore. Hence, PKW are one of the most poorly understood oceanic species of odontocetes. The dermal tissue comes primarily from stranding events that occur along the coast of the Shantou, Guangdong, China. The sampled tissues were immediately processed and attached on collagen-coated 6-well tissue culture plate. The complete medium (DMEM and Ham's F12, fetal bovine serum, antibiotic and essential amino acids) was added to the culture plates. The primary culture (PKW-LWH) cells were verified as fibroblast by vimentin and karyotype analyses, which revealed 42 autosomes and two sex chromosomes X and Y. Following transfection of PKW-LWH cells with a plasmid encoding, the SV40 large T-antigens and the transfected cells were isolated and expanded. Using RT-PCR, western blot, immunofluorescence analysis and SV40 large T-antigen stability was confirmed. The cell proliferation rate of the fibroblast cells, PKW-LWHT was faster than the primary cells PKW-LWH with the doubling time 68.9h and 14.4h, respectively. In this study, we established PKW dermal fibroblast cell line for the first time, providing a unique opportunity for in vitro studies on the effects of environmental pollutants and pathogens that could be determined in PKW and/or Cetaceans. PMID- 29596529 TI - Genome-wide identification of wheat (Triticum aestivum) expansins and expansin expression analysis in cold-tolerant and cold-sensitive wheat cultivars. AB - Plant expansins are proteins involved in cell wall loosening, plant growth, and development, as well as in response to plant diseases and other stresses. In this study, we identified 128 expansin coding sequences from the wheat (Triticum aestivum) genome. These sequences belong to 45 homoeologous copies of TaEXPs, including 26 TaEXPAs, 15 TaEXPBs and four TaEXLAs. No TaEXLB was identified. Gene expression and sub-expression profiles revealed that most of the TaEXPs were expressed either only in root tissues or in multiple organs. Real-time qPCR analysis showed that many TaEXPs were differentially expressed in four different tissues of the two wheat cultivars-the cold-sensitive 'Chinese Spring (CS)' and the cold-tolerant 'Dongnongdongmai 1 (D1)' cultivars. Our results suggest that the differential expression of TaEXPs could be related to low-temperature tolerance or sensitivity of different wheat cultivars. Our study expands our knowledge on wheat expansins and sheds new light on the functions of expansins in plant development and stress response. PMID- 29596532 TI - Intention to quit and the role of dark personality and perceived organizational support: A moderation and mediation model. AB - This study investigated the role of individual differences (dark personality) and situational factors (perceived organisational support) in explaining intention to quit. Four hundred and fifty-one (50 of which females) ambulance personnel completed three questionnaires (Hogan Development Survey; Perceived Organisational Support Survey; and a single item Intention to Quit measure) as a part of a selection and development assessment. Employees high on Excitable, Sceptical, and Mischievous, but low on Colourful were found to have greater intentions to quit. Additionally, employees high on Excitable, Sceptical, Reserved, and Leisurely, but low on Dutiful and Diligent had lower perceptions of organisational support. Structural Equation Modelling revealed that perceived organisational support plays both a mediating and moderating role on dark personality and intention to quit. Theoretical implications of personality's role in perceived organisational support and intention to quit are discussed. PMID- 29596531 TI - Insights into DNA substrate selection by APOBEC3G from structural, biochemical, and functional studies. AB - Human apolipoprotein B mRNA-editing enzyme-catalytic polypeptide-like 3 (A3) proteins are a family of cytidine deaminases that catalyze the conversion of deoxycytidine (dC) to deoxyuridine (dU) in single-stranded DNA (ssDNA). A3 proteins act in the innate immune response to viral infection by mutating the viral ssDNA. One of the most well-studied human A3 family members is A3G, which is a potent inhibitor of HIV-1. Each A3 protein prefers a specific substrate sequence for catalysis-for example, A3G deaminates the third dC in the CCCA sequence motif. However, the interaction between A3G and ssDNA is difficult to characterize due to poor solution behavior of the full-length protein and loss of DNA affinity of the truncated protein. Here, we present a novel DNA-anchoring fusion strategy using the protection of telomeres protein 1 (Pot1) which has nanomolar affinity for ssDNA, with which we captured an A3G-ssDNA interaction. We crystallized a non-preferred adenine in the -1 nucleotide-binding pocket of A3G. The structure reveals a unique conformation of the catalytic site loops that sheds light onto how the enzyme scans substrate in the -1 pocket. Furthermore, our biochemistry and virology studies provide evidence that the nucleotide binding pockets on A3G influence each other in selecting the preferred DNA substrate. Together, the results provide insights into the mechanism by which A3G selects and deaminates its preferred substrates and help define how A3 proteins are tailored to recognize specific DNA sequences. This knowledge contributes to a better understanding of the mechanism of DNA substrate selection by A3G, as well as A3G antiviral activity against HIV-1. PMID- 29596533 TI - Pluripotency gene network dynamics: System views from parametric analysis. AB - Multiple experimental data demonstrated that the core gene network orchestrating self-renewal and differentiation of mouse embryonic stem cells involves activity of Oct4, Sox2 and Nanog genes by means of a number of positive feedback loops among them. However, recent studies indicated that the architecture of the core gene network should also incorporate negative Nanog autoregulation and might not include positive feedbacks from Nanog to Oct4 and Sox2. Thorough parametric analysis of the mathematical model based on this revisited core regulatory circuit identified that there are substantial changes in model dynamics occurred depending on the strength of Oct4 and Sox2 activation and molecular complexity of Nanog autorepression. The analysis showed the existence of four dynamical domains with different numbers of stable and unstable steady states. We hypothesize that these domains can constitute the checkpoints in a developmental progression from naive to primed pluripotency and vice versa. During this transition, parametric conditions exist, which generate an oscillatory behavior of the system explaining heterogeneity in expression of pluripotent and differentiation factors in serum ESC cultures. Eventually, simulations showed that addition of positive feedbacks from Nanog to Oct4 and Sox2 leads mainly to increase of the parametric space for the naive ESC state, in which pluripotency factors are strongly expressed while differentiation ones are repressed. PMID- 29596534 TI - The characteristics of premature infants with transient corneal haze. AB - BACKGROUND: The etiology of transient corneal haze in premature infants is not known and how it relates to clinical outcomes in premature infants is not clear. OBJECTIVES: To study associated factors of transient corneal haze in premature infants. METHODS: We performed a retrospective study of 261 premature infants from retinopathy of prematurity (ROP) screening in the neonatal intensive care unit at a tertiary referral hospital. Characteristics of premature infants with and without corneal haze were analyzed by correlation tests, Chi-square tests, and logistic regressions were used for statistical analyses. Associations between corneal haze and birth weight (BW), gestational age at birth (GA), central corneal thickness, intraocular pressure, and other systemic and ophthalmic data were evaluated. RESULTS: The incidence of corneal haze was 13.4%. Lower BW, lower GA, packed red blood cells (RBC) transfusion, more days on oxygen, older maternal age, bronchopulmonary disease, and stage 3 ROP are associated with corneal haze. The severity of corneal haze decreased with infants' postmenstrual age. Multivariate logistic regression analyses revealed that BW and maternal age are the most important predictors of corneal haze. CONCLUSION: Low BW and older maternal age are the most important predictors of corneal haze in premature infants. Premature infants with corneal haze could carry more systemic and ocular morbidities. Hence they may require more clinical attention. Corneal haze is unlikely to hinder the treatment of ROP. However, it is possible that corneal haze could hinder the examination of ROP in some infants. If corneal haze does interfere with ROP screening, a closer, more conservative follow-up schedule with a senior ophthalmologist experienced in managing ROP is recommended.

AB - Academic misconduct/dishonesty has become widespread behavior among many university students across the globe, and medical education is not an exception. Until recently, few efforts have been made to study the dishonest behavior in Middle-Eastern universities. This study examined the prevalence and predisposing factors of cheating among medical students in Saudi Arabia and suggests suitable preventive measures. A cross-sectional survey-based study was conducted at a government medical college during the 2014-2015 academic year. The response rate was 58.5% (421/720). The overall cheating behavior practiced by the participants was 29%, predominantly by male students. High GPA scoring students were the least likely to cheat. The participants living with their families were more likely to cheat compared to those who were living apart from their families. The reasons participants gave to justify their cheating behavior included getting better grades, passing the course, and lacking preparation while still recognizing that cheating is a 'mistake.' Overall, significant academic misconduct concerning cheating was found among the Saudi medical students; this misconduct is alarming in a reputable government institution. The implementation of strict punishments, requiring ethical courses and creating ethical awareness by exploiting the potential of Islamic religious belief might help to control this problem.

PMID- 29596539 TI - The sociocultural effects on orthopedic surgeries in Taiwan. AB - Various sociocultural factors affect healthcare-seeking behaviors. In Taiwanese society, superstitions and lunar festivals play important roles in people's lives. We investigated the impact of "Ghost Month" (the 7th lunar month) and Chinese New Year (the 12th lunar month and the 1st lunar month of the following year) on the number of elective surgeries and emergent surgeries in Taiwan. The number of total knee replacement (TKR) surgeries and proximal femur fracture (PFF) surgeries in each lunar month from 2000 to 2011 were extracted from the Taiwan National Health Insurance Database, a computerized and population-based database. Patients were then sorted by location of residence or gender. The average number of TKR surgeries performed was significantly lower during the 1st, 7th, and 12th lunar months in urban areas, whereas in rural areas this trend was only evident in the 7th and 12th lunar months. There was however, no significant difference in the average number of PFF surgeries in each lunar month except for an increase seen in the 1st lunar month in rural patients (p<0.05). When sorted by gender, the average number of TKR surgeries was significantly decreased in the 7th and 12th lunar months in male patients, and decreased in the 1st, 7th, and 12th lunar months in female patients. In contrast, there was no difference in the average numbers of PFF surgeries in the 7th and 12th lunar months either in male or female patients. We proposed that the timing of elective surgeries such as TKR might be influenced by Ghost Month and Chinese New Year; however, emergent PFF surgeries were not significantly influenced by sociocultural beliefs and taboos in Taiwan. PMID- 29596541 TI - Association of Cerebrospinal Fluid Biomarkers of Central Nervous System Injury With Neurocognitive and Brain Imaging Outcomes in Children Receiving Chemotherapy for Acute Lymphoblastic Leukemia. AB - Importance: Little is known about treatment-related neurotoxic mechanisms in children with acute lymphoblastic leukemia (ALL) treated with chemotherapy only. Objective: To examine concentration of cerebrospinal fluid (CSF) biomarkers of brain injury at ALL diagnosis and during cancer therapy and to evaluate associations with long-term neurocognitive and neuroimaging outcomes and relevant genetic polymorphisms. Design, Setting, and Participants: This prospective cohort study included 235 patients with ALL who received a chemotherapy-only protocol. Patients provided CSF samples after diagnosis and throughout treatment. At 5 or more years after the diagnosis, 138 (69.7%) of 198 eligible survivors participated in long-term follow-up assessments. Children were treated from June 1, 2000, through October 31, 2010. Follow-up was completed on October 21, 2014, and data were analyzed from August 1, 2015, through September 30, 2016. Exposures: Plasma concentration of high-dose intravenous methotrexate sodium and number of triple intrathecal chemotherapy injections. Main Outcomes and Measures: The CSF samples were assayed at 5 points from diagnosis to reinduction for biomarkers of myelin degradation (myelin basic protein [MBP]), neuronal damage (nerve growth factor [NGF] and total and phosphorylated tau protein), astrogliosis (glial fibrillary acidic protein [GFAP]), and neuroinflammation (chitotriosidase). DNA was genotyped for polymorphisms in drug metabolism, oxidative stress, and neurodevelopment. Leukoencephalopathy was evaluated by brain imaging. At 5 or more years after the diagnosis, survivors completed neurocognitive testing and brain imaging of white matter integrity. Results: Among the 235 patients with CSF samples (120 boys [51.1%] and 115 girls [48.9%]; mean [SD] age at diagnosis, 6.8 [4.7] years), MBP and GFAP levels were elevated at baseline and through consolidation. The number of intrathecal injections was positively correlated with NGF level increase at consolidation (r = 0.19; P = .005). Increases in GFAP (risk ratio [RR], 1.23; 95% CI, 1.09-1.40), MBP (RR, 1.06; 95% CI, 1.01-1.11), and total tau (RR, 1.76; 95% CI, 1.11-2.78) levels were associated with a higher risk for leukoencephalopathy and higher apparent diffusion coefficient in frontal lobe white matter 5 years after diagnosis (standardized estimate, 0.05; P < .001). Increase in total tau at consolidation was associated with worse attention (omissions z score estimate, -0.20; P = .04). Conclusions and Relevance: Glial injury may be present at diagnosis of ALL. Neuronal injury was associated with intrathecal chemotherapy. The CSF biomarkers may be useful in identifying individuals at risk for worse neurologic outcomes, particularly those with genetic susceptibility to poor brain function.

PMID- 29596542 TI - Assessment of Tumor Sequencing as a Replacement for Lynch Syndrome Screening and Current Molecular Tests for Patients With Colorectal Cancer. AB - Importance: Universal tumor screening for Lynch syndrome (LS) in colorectal cancer (CRC) is recommended and involves up to 6 sequential tests. Somatic gene testing is performed on stage IV CRCs for treatment determination. The diagnostic workup for patients with CRC could be simplified and improved using a single up front tumor next-generation sequencing test if it has higher sensitivity and specificity than the current screening protocol. Objective: To determine whether up-front tumor sequencing (TS) could replace the current multiple sequential test approach for universal tumor screening for LS. Design, Setting, and Participants: Tumor DNA from 419 consecutive CRC cases undergoing standard universal tumor screening and germline genetic testing when indicated as part of the multicenter, population-based Ohio Colorectal Cancer Prevention Initiative from October 2015 through February 2016 (the prospective cohort) and 46 patients with CRC known to have LS due to a germline mutation in a mismatch repair gene from January 2013 through September 2015 (the validation cohort) underwent blinded TS. Main Outcomes and Measures: Sensitivity of TS compared with microsatellite instability (MSI) testing and immunohistochemical (IHC) staining for the detection of LS. Results: In the 465 patients, mean age at diagnosis was 59.9 years (range, 20-96 years), and 241 (51.8%) were female. Tumor sequencing identified all 46 known LS cases from the validation cohort and an additional 12 LS cases from the 419 member prospective cohort. Testing with MSI or IHC, followed by BRAF p.V600E testing missed 5 and 6 cases of LS, respectively. Tumor sequencing alone had better sensitivity (100%; 95% CI, 93.8%-100%) than IHC plus BRAF (89.7%; 95% CI, 78.8%-96.1%; P = .04) and MSI plus BRAF (91.4%; 95% CI, 81.0%-97.1%; P = .07). Tumor sequencing had equal specificity (95.3%; 95% CI, 92.6%-97.2%) to IHC plus BRAF (94.6%; 95% CI, 91.9%-96.6%; P > .99) and MSI plus BRAF (94.8%; 95% CI, 92.2%-96.8%; P = .88). Tumor sequencing identified 284 cases with KRAS, NRAS, or BRAF mutations that could affect therapy for stage IV CRC, avoiding another test. Finally, TS identified 8 patients with germline DPYD mutations that confer toxicity to fluorouracil chemotherapy, which could also be useful for treatment selection. Conclusions and Relevance: Up-front TS in CRC is simpler and has superior sensitivity to current multitest approaches to LS screening, while simultaneously providing critical information for treatment selection.

PMID- 29596549 TI - Preoperative Facial Nerve Mapping to Plan and Guide Pediatric Facial Vascular Anomaly Resection. AB - Importance: Facial vascular anomalies are surgical challenges due to their vascularity and facial nerve distortion. To assist facial vascular anomaly surgical treatment, presurgical percutaneous facial nerve stimulation and recording of compound motor action potentials can be used to map the facial nerve branches. During surgery, the nerve map and continuous intraoperative motor end plate potential monitoring can be used to reduce nerve injury. Objective: To investigate if preoperative facial nerve mapping (FNM) is associated with intraoperative facial nerve injury risk and safe surgical approach options compared with standard nerve integrity monitoring (NIM). Design, Setting, and Participants: This investigation was a historically controlled study at a tertiary vascular anomaly center in Seattle, Washington. Participants were 92 pediatric patients with facial vascular anomalies undergoing definitive anomaly surgery (from January 1, 1999, through January 1, 2015), with 2 years' follow-up. In retrospective review, a consecutive FNM patient cohort after 2005 (FNM group) was compared with a consecutive historical cohort (1999-2005) (NIM group). Main Outcomes and Measures: Postoperative facial nerve function and selected surgical approach. For NIM and FNM comparisons, statistical analysis calculated odds ratios of nerve injury and operative approach, and time-to-event methods analyzed operative time. Results: The NIM group had 31 patients (median age, 3.3 years [interquartile range, 2.2-11.4 years]; 20 [65%] male), and the FNM group had 61 patients (median age, 4.4 years [interquartile range, 1.5-11.0 years]; 26 [43%] male). In both groups, lymphatic malformation resection was most common (19 of 31 [61%] in the NIM group and 32 of 61 [52%] in the FNM group), and the median anomaly volumes were similar (52.4 mL; interquartile range, 12.8-183.3 mL in the NIM group and 65.4 mL; interquartile range, 18.8-180.2 mL in the FNM group). Weakness in the facial nerve branches at 2 years after surgery was more common in the NIM group (6 of 31 [19%]) compared with the FNM group (1 of 61 [2%]) (percentage difference, 17%; 95% CI, 3%-32%). Anterograde facial nerve dissection was used more in the NIM group (27 of 31 [87%]) compared with the FNM group (28 of 61 [46%]) (percentage difference, 41%; 95% CI, 24%-58%). Treatment with retrograde dissection without identification of the main trunk of the facial nerve was performed in 21 of 61 (34%) in the FNM group compared with 0 of 31 (0%) in the NIM group. Operative time was significantly shorter in the FNM group, and patients in the FNM group were more likely to complete surgery sooner (adjusted hazard ratio, 5.36; 95% CI, 2.00-14.36). Conclusions and Relevance: Facial nerve mapping before facial vascular anomaly surgery was associated with less intraoperative facial nerve injury and shorter operative time. Mapping enabled direct identification of individual intralesional and perilesional nerve branches, reducing the need for traditional anterograde facial nerve dissection, and allowed for safe removal of some lesions after partial nerve dissection through transoral or direct excision.

PMID- 29596551 TI - Thyroidectomy Practice After Implementation of the 2015 American Thyroid Association Guidelines on Surgical Options for Patients With Well-Differentiated Thyroid Carcinoma. AB - Importance: The recommended extent of surgery for well-differentiated thyroid carcinoma has been modified considerably in the updated 2015 American Thyroid Association guidelines published in January 2016. To date, the changes in clinical practice after publication of these new guidelines have not been demonstrated. Objective: The aim of this study was to evaluate clinical practice changes associated with implementation of the updated guidelines on the surgical procedure rates of total thyroidectomy, thyroid lobectomy, and completion thyroidectomy at a single tertiary medical center. Design, Setting, and Participants: This is a retrospective cohort study of 169 patients at the Hadassah-Hebrew University Medical Center, Jerusalem, Israel. Patients with pathologically proved, well-differentiated thyroid carcinoma who underwent surgery between January 1, 2013, and December 31, 2014, were compared with patients who underwent surgery from January 1 to December 31, 2016. A total of 434 thyroidectomy procedures were performed during the study period, and 251 had pathologically proved, well-differentiated thyroid carcinoma. Patients with tumors larger than 4 cm, involved lymph nodes, or bilateral nodules were excluded. Main Outcomes and Measures: Primary outcomes were the rate of up-front total thyroidectomy vs lobectomy and the rates of completion thyroidectomy before and after the implementation of the new guidelines. Results: Of the 169 patients in the final analysis, 118 (69.8%) were included from 2013 to 2014 and 51 (30.2%) in 2016. The mean (SD) age for the entire cohort was 44 (13.8) years, and 129 (76.3%) were women. Up-front total thyroidectomy was performed in 72 of 118 patients (61.0%) prior to the 2015 American Thyroid Association guidelines and 16 of 51 (31.4%) following their implementation (odds ratio, 0.29; 95% CI, 0.14 0.59). The rate of completion thyroidectomy also significantly decreased between these periods (73.9% vs 20.0%; odds ratio, 0.09; 95% CI, 0.04-0.19). Conclusions and Relevance: The updated 2015 American Thyroid Association guidelines implementation was associated with a significant decrease in the rates of both up front total thyroidectomy and completion thyroidectomy. According to these findings, only 1 of 5 patients who undergoes thyroid lobectomy will require a completion procedure. PMID- 29596552 TI - Yield, Techniques, and Complications of Transvitreal and Transscleral Biopsies in Small Uveal Melanoma. AB - Importance: Intraoperative adequacy check of biopsy samples can lead to a higher biopsy yield rate, and subsequent genomic analysis can provide patients with valuable prognostic information. Objectives: To examine the yield rates for transscleral and transvitreal fine-needle aspiration biopsies of small uveal melanoma less than 3.6 mm in apical height and to discuss techniques that would maximize yield rates and minimize complications. Design, Setting, and Participants: A retrospective, consecutive observational case series was conducted from January 29, 2013, to May 23, 2017, at Retina Consultants of Houston and Houston Methodist Hospital among 44 patients with uveal melanoma of the ciliary body or choroid. Interventions or Exposures: Fine-needle aspiration biopsy and intraoperative histopathologic analysis prior to iodine 125 brachytherapy. Main Outcomes and Measures: Tumor locations and dimensions were identified by histopathologic analysis and B-scan ultrasonography. Either transscleral or transvitreal biopsy was performed for tumors anterior to the equator and posterior to the equator, respectively. Biopsy specimens were checked for adequacy intraoperatively. Specimens were examined using hematoxylin-eosin, double immunostain with human melanoma black 45 and Ki67, and gene expression profile. Results: A total of 44 patients were included in the study, with a mean (SD) age of 63.3 (12.7) years (21 men [47.7%]; 23 women [52.3%]). Median tumor height was 2.7 mm (interquartile range, 2.3- 2.9 mm). Forty of 44 biopsy samples (90.9%; 95% CI, 82.4%-99.4%) yielded adequate cells for gene expression profile analysis. Transscleral and transvitreal yield rates were 11 of 11 (100%) and 29 of 33 (87.9%), respectively. Most localized vitreous hemorrhages were resolved by 3 months. There was a moderate association between localized vitreous hemorrhage and transvitreal biopsy method, for which the phi value was -0.526 (95% CI, 0.712 to -0.157; P < .001). Conclusions and Relevance: These findings suggest intraoperative adequacy evaluation of fine-needle aspiration biopsy specimens leads to high yield and is more informative for patients. PMID- 29596553 TI - Association of Vitamin A Supplementation With Disease Course in Children With Retinitis Pigmentosa. AB - Importance: While oral vitamin A supplementation is considered to potentially slow loss of retinal function in adults with retinitis pigmentosa and normal liver function, little data from children with this disease are available. Objective: To compare disease courses in children with retinitis pigmentosa taking or not taking vitamin A supplementation. Design, Setting, and Participants: Retrospective, nonrandomized comparison of vitamin A and control cohorts followed up for a mean of 4 to 5 years by the Electroretinography Service of the Massachusetts Eye and Ear Infirmary. The study included children with different genetic types of typical retinitis pigmentosa: 55 taking vitamin A and 25 not taking vitamin A. The dates for patient evaluations ranged from June 1976 to July 2016, and the data analysis occurred in October 2016. Interventions: Age adjusted dose of oral vitamin A palmitate (<=15 000 IU/d). Main Outcomes and Measures: Mean exponential rates of change of full-field cone electroretinogram amplitude to 30-Hz flashes estimated by repeated-measures longitudinal regression without and with adjusting for potential confounders. Results: Of the 55 children in the vitamin A cohort, 38 (69%) were male; the mean [SD] age was 9.1 [1.9] years; and 48 (87%) were white , 6 (11%) were Asian, and 1 (2%) was black. Of the 25 members of the control cohort, 19 (76%) were male; the mean [SD] age was 9.2 [1.7] years; and 25 (100%) were white. The estimated mean rates of change with the unadjusted model were -0.0713 loge unit/y (-6.9% per year) for the vitamin A cohort and -0.1419 loge unit per year (-13.2% per year) for the control cohort (difference, 0.0706 loge unit per year; 95% CI for the difference, 0.0149-0.1263 loge unit per year; P = .01). The adjusted model confirmed a slower mean rate of decline in the vitamin A cohort (difference, 0.0771 loge-unit per year; 95% CI for the difference, 0.0191-0.1350 loge-unit per year; P = .009). With respect to ocular safety, the mean exponential rates of change of visual field area and visual acuity and the incidences of falling to a visual field diameter of 20 degrees or less or a visual acuity of 20/200 or less in at least 1 eye did not differ by cohort. Conclusions and Relevance: A vitamin A palmitate supplement was associated with a slower loss of cone electroretinogram amplitude in children with retinitis pigmentosa. Although the relatively small-sample, retrospective, nonrandomized design does not allow a test of causation and is subject to possible biases, these findings support consideration of an age-adjusted dose of vitamin A in the management of most children with the common forms of retinitis pigmentosa.

PMID- 29596556 TI - Uveal Melanoma Associated With Myotonic Dystrophy: A Report of 6 Cases. AB - Importance: Patients with myotonic dystrophy (MD) have an increased risk of malignancy including uveal melanoma. This case series further explores the association between these 2 diseases. Objective: To describe a cohort of patients with uveal melanoma associated with MD, including a case of iris melanoma, and MD associated uveal melanoma in relatives. Design, Setting, and Participants: Retrospective case series at 3 tertiary referral centers (Wills Eye Hospital, Philadelphia, Pennsylvania; Mayo Clinic, Rochester, Minnesota; and Moorfields Eye Hospital, London, England), between January 1, 2000, and August 31, 2017. The study included 6 patients with MD and uveal melanoma. Main Outcomes and Measures: Melanoma response to treatment and development of metastatic disease. Results: There were 6 patients, 4 men and 2 women, with MD and uveal melanoma. The mean patient age at melanoma diagnosis was 47 years (median, 43 years; range, 30-67 years), and the tumor involved the choroid in 5 patients (83%) and iris in 1 patient (17%). The diagnosis of MD was known since young adulthood in 2 patients (33%) and was discovered in adulthood in 4 patients (67%). The main clinical features of MD included muscle weakness (n = 5; 83%), myotonia (n = 4; 67%), polychromatic cataract (n = 4; 67%), complications with general anesthesia (n = 4; 67%), myalgia (n = 3; 50%), cardiac arrhythmia (n = 2; 33%), and frontal baldness (n = 2; 33%). Genetic testing revealed MD type 1 (4 of 4 tested patients), and 2 patients demonstrated positive family history of MD with classic clinical features and preferred no testing. Melanoma treatment included plaque radiotherapy (n = 4; 67%), photodynamic therapy (n = 1; 17%), and declined treatment (n = 1; 17%). At follow-up of 6, 6, 41, 42, and 87 months (5 patients), findings included melanoma regression (4 of 5 tumors), melanoma recurrence (1 of 5 tumors), and no metastatic disease (5 of 5 patients). Conclusions and Relevance: Six adult patients with MD demonstrated uveal melanoma involving the choroid or iris, emphasizing the association between these 2 diseases. Further research seems warranted to explore the pathogenesis of uveal melanoma in MD. These findings support the consideration of ophthalmic examination for uveal melanoma in patients with MD.

PMID- 29596559 TI - Stochastic modelling of tree architecture and biomass allocation: application to teak (Tectona grandis L. f.), a tree species with polycyclic growth and leaf neoformation. AB - Background and aims: For a given genotype, the observed variability of tree forms results from the stochasticity of meristem functioning and from changing and heterogeneous environmental factors affecting biomass formation and allocation. In response to climate change, trees adapt their architecture by adjusting growth processes such as pre- and neoformation, as well as polycyclic growth. This is the case for the teak tree. The aim of this work was to adapt the plant model, GreenLab, in order to take into consideration both these processes using existing data on this tree species. Methods: This work adopted GreenLab formalism based on source-sink relationships at organ level that drive biomass production and partitioning within the whole plant over time. The stochastic aspect of phytomer production can be modelled by a Bernoulli process. The teak model was designed, parameterized and analysed using the architectural data from 2- to 5-year-old teak trees in open field stands. Key results: Growth and development parameters were identified, fitting the observed compound organic series with the theoretical series, using generalized least squares methods. Phytomer distributions of growth units and branching pattern varied depending on their axis category, i.e. their physiological age. These emerging properties were in accordance with the observed growth patterns and biomass allocation dynamics during a growing season marked by a short dry season. Conclusions: Annual growth patterns observed on teak, including shoot pre- and neoformation and polycyclism, were reproduced by the new version of the GreenLab model. However, further updating is discussed in order to ensure better consideration of radial variation in basic specific gravity of wood. Such upgrading of the model will enable teak ideotypes to be defined for improving wood production in terms of both volume and quality. PMID- 29596560 TI - The Influence of Preoperative Interventions on Postoperative Surgical Wound Healing in Patients Without Risk Factors: A Systematic Review. AB - Background: Poor wound healing and scar formation remain critical problems in daily surgical practice. Generally, most attention is paid to intra- and postoperative interventions to improve wound healing after surgery, while preoperative interventions remain unsatisfactorily explored. Objectives: In this systematic review, the available literature on the beneficial effects of preoperative interventions on wound healing and scar formation have been summarized and compared. Methods: A comprehensive and systematic search has been conducted in MEDLINE, Pubmed, Embase, Web of Science, and Cochrane, supplemented by reference and citation tracking. All preoperative interventions and all clinically relevant outcome parameters have been considered for inclusion, due to the expected limited availability of literature. Results: A total of 13 studies were included, which were all randomized trials. No cohort studies or retrospective studies have been identified. All studies described different preoperative interventions and outcome parameters and could hence not be pooled and compared. Eight studies showed significantly better wound healing after a preoperative intervention. The individual studies have been summarized in this review. Conclusions: This systemic review shows that preoperative interventions can be beneficial in improving wound healing and scar formation. In selected cases, wound healing was found to benefit from a higher preoperative body temperature, topical vitamin E application, and low patient stress levels. Level of Evidence 2: PMID- 29596561 TI - Standardization of left atrial, right ventricular, and right atrial deformation imaging using two-dimensional speckle tracking echocardiography: a consensus document of the EACVI/ASE/Industry Task Force to standardize deformation imaging. AB - The EACVI/ASE/Industry Task Force to standardize deformation imaging prepared this consensus document to standardize definitions and techniques for using two dimensional (2D) speckle tracking echocardiography (STE) to assess left atrial, right ventricular, and right atrial myocardial deformation. This document is intended for both the technical engineering community and the clinical community at large to provide guidance on selecting the functional parameters to measure and how to measure them using 2D STE.This document aims to represent a significant step forward in the collaboration between the scientific societies and the industry since technical specifications of the software packages designed to post-process echocardiographic datasets have been agreed and shared before their actual development. Hopefully, this will lead to more clinically oriented software packages which will be better tailored to clinical needs and will allow industry to save time and resources in their development.

PMID- 29596562 TI - Salinity induction of recycling Crassulacean acid metabolism and salt tolerance in plants of Talinum triangulare. AB - Background and Aims: Crassulacean acid metabolism (CAM) can be induced by salinity, thus conferring the plant higher water-use efficiency. Talinum triangulare does not frequently encounter salt in its natural habitat but is cultivated in soils that may become salinized. Here we examined whether plants of T. triangulare can grow in saline soils and show salt-induced CAM. Methods: Leaf gas exchange, carbon isotopic ratio (delta13C), nocturnal acid accumulation (DeltaH+), water relations, photosynthetic pigment and mineral contents, leaf anatomy and growth were determined in greenhouse in plants irrigated with 0, 150, 300 and 400 mm NaCl. Key Results: Salinity reduced gas exchange and induced CAM, DeltaH+ reaching 50.2 MUmol H+ g-1 fresh mass under 300 mm NaCl. No nocturnal CO2 uptake, but compensation, was observed. Values of delta13C were lowest under 0 and 400 mm NaCl, and highest under 150 and 300 mm. The difference in osmotic potential (psis) between control and treated plants averaged 0.45 MPa for the three [NaCl] values, the decrease in psis being accounted for by up to 63 % by Na+ and K+. Pigment contents were unaffected by treatment, suggesting lack of damage to the photosynthetic machinery. Changes in stomatal index with unchanged stomatal density in newly expanded leaves suggested inhibited differentiation of epidermal cells into stomata. Whole-leaf and parenchymata thickness increased under 150 and 300 mm NaCl. Only plants irrigated with 400 mm NaCl showed reductions in biomass (stems, 41 %; reproductive structures, 78 %). The K/Na molar ratio decreased with [NaCl] from 2.0 to 0.4. Conclusions: The operation of CAM in the recycling mode was evidenced by increased DeltaH+ with no nocturnal CO2 uptake. Talinum triangulare can be classified as a halo-tolerant species based on its low K/Na molar ratio under salinity and the relatively small reduction in growth only at the highest [NaCl]. PMID- 29596565 TI - Midlife Predictors of Health-Related Quality of Life in Older Women. AB - Background: Midlife represents an important time to evaluate health status and health behaviors that may affect health-related quality of life (HRQL) in later years. This study examines change in women's HRQL over 11 years from ages 47-59 to 57-69 and identifies midlife characteristics that predict HRQL at older ages. Methods: Physical (PCS) and mental component summaries (MCS) of the SF-36 were used to assess HRQL from 2002 to 2013 in 2,614 women from the Study of Women's Health Across the Nation (SWAN), a multiethnic/racial cohort study. We used locally weighted scatterplot smoothing (LOESS) models to obtain unadjusted predicted mean trajectories of PCS and MCS as a function of age. Results: LOESS predicted PCS declined from 51.6 to 47.1, whereas MCS increased from 49.2 to 53.1. In multivariable models, controlling for baseline PCS, higher baseline physical activity (p = .002) and increase in physical activity from baseline (p < .0001) predicted better PCS. Time since baseline (ie, aging; p < .001), higher baseline body mass index (p < .0001), increased body mass index over time (p < .0001), smoking (p < .05), two or more medical conditions (p < .0001), sleep problems (p < .0001), and urinary incontinence (p < .0001) were related to lower PCS. Early (p = .004) and late postmenopause (p = .001; vs. premenopause) and aging (p = .05) predicted higher MCS. Predictors of lower MCS were less than very good health (p < .0001), sleep problems (p < .0001), stressful life events (p < .0001), higher perceived stress (p < .0001), and higher trait anxiety (p = .004). Race/ethnicity was related to MCS, but not PCS. Conclusions: Several potentially modifiable midlife factors, such as improved sleep hygiene, physical activity, and body mass index, might improve HRQL for older women.

PMID- 29596567 TI - Malignant disease as a comorbidity in patients with severe aortic stenosis: clinical presentation, outcomes, and management. AB - Aim: To investigate the effect of malignancy on the outcomes of patients with severe aortic stenosis (AS) and the management strategy for AS with malignancy. Methods and results: Using data of 3815 patients with severe AS in a retrospective multicentre registry [CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) registry], we compared 3-year clinical outcomes among three groups based on malignancy status: with malignancy currently under treatment including best supportive care (malignancy group), with a history of malignancy without any current treatment (past history group), or without history of malignancy (no malignancy group). Patients in the malignancy group (n = 124) were more often men and had higher prevalence of low body mass index, recurrence of malignancy, anaemia, and asymptomatic status, despite comparable surgical risks and echocardiographic parameters. The malignancy group or the past history group (n = 389) had significantly higher risk for all-cause death [hazard ratio (HR) 2.49, 95% CI (95% confidence interval) 1.98-3.14; HR 1.23, 95% CI 1.04-1.46] and for malignancy-related death (HR 16.2, 95% CI 10.64-24.54; HR 3.66, 95% CI 2.43-5.52) than that of the no malignancy group (n = 3302). The excess risk for aortic valve related death was not observed in the malignancy group (HR 0.79, 95% CI 0.48 1.29) and was lower in the past history group (HR 0.72, 95% CI 0.53-0.96). In the malignancy group, the treatment strategy (surgery: n = 16, conservative management: n = 108) was determined based on the clinical status of AS or life expectancy. Conclusions: Malignancy had marked effect on all-cause death and malignancy-related death in patients with severe AS. History of malignancy also had a smaller but significant effect on mortality. PMID- 29596568 TI - Effects of the Tongue-in-Groove Maneuver on Nasal Tip Rotation. AB - Background: A change in nasal tip rotation is a very common maneuver performed during rhinoplasty. Among the many techniques used to achieve this goal is the tongue-in-groove (TIG). Objectives: This study addresses the long-term effect of the TIG on the nasal tip rotation 1 year after rhinoplasty. Methods: The authors prospectively identified patients who were submitted to a rhinoplasty with a TIG maneuver over a period of 1 year. The angle of rotation was measured along the nostril axis angle. The data were analyzed using the t test and a linear regression model. Results: Seventeen patients were included. The average preoperative tip rotation was 93.95 degrees (SD, 3.12 degrees ). Immediate postoperative tip rotation averaged 114.47 degrees (SD, 3.79 degrees ). At the 1 year follow-up appointment, the tip rotation averaged 106.55 degrees (SD, 3.54 degrees ). There was a significant loss of rotation at the 1-year postoperative visit (P < 0.0001), with an average loss of 7.9 degrees (SD, 3.25 degrees ), which amounted to 6.8%. The preoperative rotation didn't affect the amount of loss of rotation (P = 0.04). It can be estimated that, for every degree of rotation that is changed at surgery, the tip can be expected to lose 0.35 degrees over the first year. Conclusions: TIG is a more dependable technique than the ones that rely on healing and contraction to obtain rotation. Our data demonstrated a significant loss of rotation during the first year. This suggests that the surgeon needs to slightly overcorrect the tip rotation to account for this loss. Level of Evidence 4: PMID- 29596569 TI - Interferon-gamma inhibits seminal plasma induction of colony-stimulating factor 2 in mouse and human reproductive tract epithelial cells. AB - Seminal fluid interacts with the female reproductive tract to initiate a permissive immune response that facilitates embryo implantation and pregnancy success. The immune-regulatory cytokine interferon-gamma (IFNG), which can be elevated in seminal plasma, is associated with reduced fertility. Here, we investigated how IFNG influences the female immune response to seminal fluid. In human Ect1 cervical epithelial cells, IFNG added at physiologically relevant concentrations substantially impaired seminal plasma-induced synthesis of key cytokines colony-stimulating factor 2 (CSF2) and interleukin-6 (IL6). Seminal fluid-induced CSF2 synthesis was also suppressed in the uterus of mice in vivo, when IFNG was delivered transcervically 12 h after mating. Transforming growth factor B1 (TGFB1) is the major seminal fluid signaling factor which elicits CSF2 induction, and IFNG exhibited potent dose-dependent suppression of CSF2 synthesis induced by TGFB1 in murine uterine epithelial cells in vitro. Similarly, IFNG suppressed TGFB1-mediated CSF2 induction in Ect1 cells and human primary cervical epithelial cells; however, IL6 regulation by IFNG was independent of TGFB1. Quantitative PCR confirmed that CSF2 regulation by IFNG in Ect1 cells occurs at the gene transcription level, secondary to IFNG suppression of TGFBR2 encoding TGFB receptor 2. Conversely, TGFB1 suppressed IFNG receptor 1 and 2 genes IFNGR1 and IFNGR2. These data identify IFNG as a potent inhibitor of the TGFB-mediated seminal fluid interaction with relevant reproductive tract epithelia in mice and human. These findings raise the prospect that IFNG in the male partner's seminal fluid impairs immune adaptation for pregnancy following coitus in women. PMID- 29596570 TI - Integrated Forehead and Temporal Augmentation Using 3D Printing-Assisted Methyl Methacrylate Implants. AB - Background: Achieving aesthetic results with forehead augmentation procedures remains challenging. We have developed a method of integrated forehead and temporal augmentation using a three-dimensional (3D) printing-assisted methyl methacrylate implant. Objectives: The study objective was to assess the importance of combined temporal augmentation when performing forehead augmentation. Methods: We identified 34 patients (from 2000 to 2010) who underwent forehead augmentation with a methyl methacrylate implant contoured in situ during surgery and 41 patients (from 2010 to 2016) who underwent integrated forehead and temporal augmentation with a prefabricated methyl methacrylate implant. We conducted a retrospective chart review of patient data including operation time, complications, and instances of revision surgery. Two blinded plastic surgeons scored the aesthetic results of the operations on a 4-point scale (1, poor, to 4, excellent) based on preoperative and posttreatment photographs. Results: The integrated augmentation method resulted in a lower frequency of posttreatment implant removal (one [2%] vs. six [18%]; P < .05), a lower frequency of filler injection for touch up (one [2%] vs. six [18%]; P < .05), and higher mean aesthetic scores (3.7 +/- 0.5 vs. 2.2 +/- 1.0; P < . 001) compared to the forehead augmentation method. There was no statistically significant difference in surgical complications between the two groups. Conclusions: Integrated forehead and temporal augmentation using a 3D printing assisted methyl methacrylate implant may be the optimal available procedure, enabling the custom fabrication of contours requested by the patient and providing a rejuvenating and balancing effect on facial appearance. Level of Evidence 3: PMID- 29596572 TI - Structural and functional analyses of microbial metabolic networks reveal novel insights into genome-scale metabolic fluxes. AB - We present here an integrated analysis of structures and functions of genome scale metabolic networks of 17 microorganisms. Our structural analyses of these networks revealed that the node degree of each network, represented as a (simplified) reaction network, follows a power-law distribution, and the clustering coefficient of each network has a positive correlation with the corresponding node degree. Together, these properties imply that each network has exactly one large and densely connected subnetwork or core. Further analyses revealed that each network consists of three functionally distinct subnetworks: (i) a core, consisting of a large number of directed reaction cycles of enzymes for interconversions among intermediate metabolites; (ii) a catabolic module, with a largely layered structure consisting of mostly catabolic enzymes; (iii) an anabolic module with a similar structure consisting of virtually all anabolic genes; and (iv) the three subnetworks cover on average ~56, ~31 and ~13% of a network's nodes across the 17 networks, respectively. Functional analyses suggest: (1) cellular metabolic fluxes generally go from the catabolic module to the core for substantial interconversions, then the flux directions to anabolic module appear to be determined by input nutrient levels as well as a set of precursors needed for macromolecule syntheses; and (2) enzymes in each subnetwork have characteristic ranges of kinetic parameters, suggesting optimized metabolic and regulatory relationships among the three subnetworks. PMID- 29596571 TI - Roles for endothelial cell and macrophage Gch1 and tetrahydrobiopterin in atherosclerosis progression. AB - Aims: GTP cyclohydrolase I catalyses the first and rate-limiting reaction in the synthesis of tetrahydrobiopterin (BH4), an essential cofactor for nitric oxide synthases (NOS). Both eNOS and iNOS have been implicated in the progression of atherosclerosis, with opposing effects in eNOS and iNOS knockout mice. However, the pathophysiologic requirement for BH4 in regulating both eNOS and iNOS function, and the effects of loss of BH4 on the progression of atherosclerosis remains unknown. Methods and results: Hyperlipidemic mice deficient in Gch1 in endothelial cells and leucocytes were generated by crossing Gch1fl/flTie2cre mice with ApoE-/- mice. Deficiency of Gch1 and BH4 in endothelial cells and myeloid cells was associated with mildly increased blood pressure. High fat feeding for 6 weeks in Gch1fl/flTie2CreApoE-/- mice resulted in significantly decreased circulating BH4 levels, increased atherosclerosis burden and increased plaque macrophage content. Gch1fl/flTie2CreApoE-/- mice showed hallmarks of endothelial cell dysfunction, with increased aortic VCAM-1 expression and decreased endothelial cell dependent vasodilation. Furthermore, loss of BH4 from pro inflammatory macrophages resulted in increased foam cell formation and altered cellular redox signalling, with decreased expression of antioxidant genes and increased reactive oxygen species. Bone marrow chimeras revealed that loss of Gch1 in both endothelial cells and leucocytes is required to accelerate atherosclerosis. Conclusion: Both endothelial cell and macrophage BH4 play important roles in the regulation of NOS function and cellular redox signalling in atherosclerosis. PMID- 29596573 TI - Longevity Around the Turn of the 20th Century: Life-Long Sustained Survival Advantage for Parents of Today's Nonagenarians. AB - Members of longevous families live longer than individuals from similar birth cohorts and delay/escape age-related diseases. Insight into this familial component of longevity can provide important knowledge about mechanisms protecting against age-related diseases. This familial component of longevity was studied in the Leiden Longevity Study which consists of 944 longevous siblings (participants), their parents (N = 842), siblings (N = 2,302), and spouses (N = 809). Family longevity scores were estimated to explore whether human longevity is transmitted preferentially through the maternal or paternal line. Standardized mortality ratios (SMRs) were estimated to investigate whether longevous siblings have a survival advantage compared with longevous singletons and we investigated whether parents of longevous siblings harbor a life-long sustained survival advantage compared with the general Dutch population by estimating lifetime SMRs (L-SMRs). We found that sibships with long-lived mothers and non-long-lived fathers had 0.41 (p = .024) less observed deaths than sibships with long-lived fathers and non-long-lived mothers and 0.48 (p = .008) less observed deaths than sibships with both parents non-long lived. Participants had 18.6 per cent less deaths compared with matched singletons and parents had a life-long sustained survival advantage (L-SMR = 0.510 and 0.688). In conclusion, genetic longevity studies may incorporate the maternal transmission pattern and genes influencing the entire life-course of individuals. PMID- 29596574 TI - Efficacy and Safety of Autologous Fat Transfer in Facial Reconstructive Surgery: A Systematic Review and Meta-analysis. AB - Importance: The use of autologous fat transfer (AFT) or lipofilling for correcting contour deformities is seen as one of the major breakthroughs in reconstructive plastic surgery. Its applications in facial reconstructive surgery have been of particular interest owing to the prospect of achieving autologous reconstruction by a minimally invasive approach. However, its unpredictability and variable degree of resorption have limited its utility and much skepticism still exists regarding its efficacy. Furthermore, more than 2 decades of clinical research have produced a highly fragmented body of evidence that has not been able to provide definite answers. Objective: To investigate the safety and efficacy of AFT in facial reconstruction through a systematic review and meta analysis. Data Sources: A literature search was performed in PubMed, Embase, and the Cochrane Library from inception to October 11, 2017. Study Selection: All published studies investigating the efficacy and safety of AFT in facial reconstructive surgery. Data Extraction and Synthesis: Two independent reviewers performed data extraction systematically, adhering to the PRISMA guidelines. Summary measures were pooled in a random-effects model meta-analysis. Main Outcomes and Measures: The patient and surgeon satisfaction, graft survival, number of AFT sessions, and the incidence of AFT-related complications were the main outcomes of interest in this meta-analysis. Results: This systematic review resulted in the inclusion 52 relevant studies consisting of 1568 unique patients. These included 4 randomized clinical trials, 11 cohort studies, and 37 case series. The overall follow-up averaged 1.3 years after AFT. Meta-analysis revealed a very high overall patient satisfaction rate of 91.1% (95% CI, 85.1% 94.8%) and overall surgeon satisfaction rate of 88.6% (95% CI, 83.4%-92.4%). The number of AFT sessions required to achieve the desired result was 1.5 (95% CI, 1.3-1.7) and 50% to 60% of the injected volume was retained at 1 year. Only 4.8% (95% CI, 3.3%-6.9%) of procedures resulted in clinical complications. Conclusions and Relevance: To our knowledge, this study provides the first overview of the current knowledge about AFT in facial reconstructive surgery. Our results confirm that AFT is an effective technique for treating soft-tissue deformities in the head and neck, with low rate of minor complications. Level of Evidence: NA.

AB - Aims: Scavenger receptor Class B Type 1 (SR-BI) is a major receptor for high density lipoprotein (HDL) that promotes hepatic uptake of cholesterol from HDL. A rare mutation p.P376L, in the gene encoding SR-BI, SCARB1, was recently reported to associate with elevated HDL cholesterol (HDL-C) and increased risk of coronary artery disease (CAD), suggesting that increased HDL-C caused by SR-BI impairment might be an independent marker of cardiovascular risk. We tested the hypothesis that alleles in or close to SCARB1 that associate with elevated levels of HDL-C also associate with increased risk of CAD in the relatively homogeneous population of Iceland. Methods and results: Using a large resource of whole genome sequenced Icelanders, we identified thirteen SCARB1 coding mutations that we examined for association with HDL-C (n = 136 672). Three rare SCARB1 mutations, encoding p.G319V, p.V111M, and p.V32M (combined allelic frequency = 0.2%) associate with elevated levels of HDL-C (p.G319V: beta = 11.1 mg/dL, P = 8.0 * 10-7; p.V111M: beta = 8.3 mg/dL, P = 1.1 * 10-6; p.V32M: beta = 10.2 mg/dL, P = 8.1 * 10-4). These mutations do not associate with CAD (36 886 cases/306 268 controls) (odds ratio = 0.90, 95% confidence interval 0.67-1.22, P = 0.49), despite effects on HDL-C comparable to that reported for p.P376L, both in terms of direction and magnitude. Furthermore, HDL-C raising alleles of three common SCARB1 non-coding variants, including one previously unreported (rs61941676-C: beta = 1.25 mg/dL, P = 1.7 * 10-18), and of one low frequency coding variant (p.V135I) that independently associate with higher HDL-C, do not confer increased risk of CAD. Conclusion: Elevated HDL-C due to genetically compromised SR-BI function is not a marker of CAD risk. PMID- 29596579 TI - Observed smoking and tobacco pack display in Australian outdoor cafes 2 years after implementation of plain packaging. AB - Background: Implementation of tobacco plain packaging (PP) in Australia in December 2012 was associated with significant reductions in the percentage of patrons at outdoor cafes observed to be displaying tobacco packs and actively smoking, immediately post-implementation and 1 year later. This study examines whether these positive effects were sustained through to 2 years post-PP. Methods: An observational study conducted at cafes, restaurants and bars with outdoor seating in Melbourne, Australia documented the number of: patrons; patrons actively smoking; tobacco packs on display; orientation and type of displayed packs and whether or not children were present. Data were collected pre PP (2012), early post-PP (2013), 1 year post-PP (2014) and 2 years post-PP (2015). Multilevel Poisson regressions analyzed changes in each outcome, adjusting for important covariates. Results: Overall, positive effects of PP implementation on tobacco pack display and active smoking were not fully sustained through to 2 years post-PP for the total sample. Interactions between phase and the presence of children indicated that pack display and active smoking were lower in all post-implementation phases (compared with pre-PP) at venues where children were present but not at venues where children were not present. Conclusions: Children at outdoor cafes were still being exposed to less tobacco packaging and active smoking, 2 years after implementation of the packaging changes. More regular refreshment of graphic health warnings is likely to be required to sustain these effects, and to reduce pack display behaviour at venues with no children.

AB - OBJECTIVES: The emergence of ultra-high-volume centres promises new opportunities for thoracic surgical training. The goal of this study was to investigate the effectiveness of a novel observership course in teaching video-assisted thoracoscopic surgery (VATS) at an ultra-high-volume centre. METHODS: Two-week courses in VATS at a specialist unit now performing >10 000 major lung resections annually (>50 daily on average) were attended by 230 surgeons from around the world from 2013 to 2016. An online survey preserving responder anonymity was completed by 156 attendees (67.8%). RESULTS: Attendees included 37% from Western Europe, 18% from Eastern Europe and 17% from Latin America. Experience with open thoracic surgery for more than 5 years was reported by 67%, but 79% had less than 5 years of VATS lobectomy experience. During the course, 70% observed over 30 uniportal VATS operations (including 38% observing over 50), and 69% attended an animal wet lab. Although 72% of the responders attended the course less than 12 months ago, the number of ports used (P < 0.001), operation times (P < 0.001) and conversion rates (P < 0.001) reported by the responders were reduced significantly after the course. Improvements in the problem areas of tissue retraction, instrumentation, stapler application and coordination with the assistant during VATS were reported by 56%, 57%, 58% and 53%, respectively. Of those who had attended other VATS courses previously, 87% preferred the training from this high-volume course. CONCLUSIONS: High-volume intensive observership training at an ultra-high-volume centre may improve VATS proficiency in a short period of time, and may provide a time-efficient modality for future thoracic surgical training. PMID- 29596582 TI - Prevalence of Posttraumatic Stress Disorder in Prisoners. AB - People involved with criminal justice frequently are exposed to violence and traumatic experiences. This may lead to posttraumatic stress disorder (PTSD); however, no review, to our knowledge, has synthetized findings in this setting. We conducted a systematic review and meta-analysis to estimate prevalence rates of PTSD in prison populations. Original studies in which prevalence rates of PTSD in unselected samples of incarcerated people were reported were systematically searched between 1980 and June 2017. Data were pooled using random-effects meta analysis, and sources of heterogeneity for prespecified characteristics were assessed by meta-regression. We identified 56 samples comprising 21,099 imprisoned men and women from 20 countries. Point prevalence of PTSD ranged from 0.1% to 27% for male, and from 12% to 38% for female prisoner populations. The random-effects pooled point prevalence was 6.2% (95% confidence interval: 3.9, 9.0) in male prisoners and 21.1% (95% confidence interval: 16.9, 25.6) in female prisoners. The heterogeneity between the included studies was very high. Higher prevalence was reported in samples of female prisoners, smaller studies (n <= 200), and for investigations based in high-income countries. Existing evidence shows high levels of PTSD among imprisoned people, especially women. Psychosocial interventions to prevent violence, especially against children and women, and to mitigate its consequences in marginalized communities must be improved. Trauma informed approaches for correctional programs and scalable PTSD treatments in prisons require further consideration.

AB - Importance: While the prevalence of age-related macular degeneration (AMD) differs according to continents and races/ethnicities, its incidence in the European continent has been scarcely documented. Objective: To describe the incidence and associated risk factors of AMD in elderly French individuals. Design, Setting, and Participants: This population-based cohort study of 963 residents of Bordeaux, France, who were 73 years or older at baseline and participated in the Antioxydants, Lipides Essentiels, Nutrition et Maladies Oculaires (ALIENOR) Study between October 2, 2006, and December 21, 2012. Of 829 participants at risk for incident AMD, 659 (79.5%) were observed for a mean (SD) duration of 3.8 (1.1) years. Data were analyzed from August 2016 to March 2017. Main Outcomes and Measures: Age-related macular degeneration was graded from retinal photographs and spectral-domain optical coherence tomography into 5 exclusive stages: no AMD, early AMD1, early AMD2, late atrophic AMD, and late neovascular AMD. Results: Of the 659 eligible participants, 413 (62.7%) were women, and the mean (SD; range) age was 79.7 (4.4; 73-94) years. A total of 120 incident cases of early AMD and 45 incident cases of advanced AMD were recorded. Incidence rates of early and advanced AMD were 79.9 (95% CI, 66.8-95.5) per 1000 person-years and 18.6 (95% CI, 13.9-24.9) per 1000 person-years, respectively, corresponding to 5-year risks of 32.9% and 8.9%. Incidence of advanced AMD per 1000 eye-years was 1.5 in eyes without any AMD at baseline, 42.4 in those with early AMD1, and 85.1 in those with early AMD2. In multivariate analysis without correction for multiple testing, progression from early to advanced AMD was associated with AMD grade in the fellow eye (hazard ratio [HR] according to grade, 13.0 [95% CI, 2.8-61.2] to 22.5 [95% CI, 2.6-195.9]), having smoked at least 20 pack-years (calculated as number of smoking years * mean number of cigarettes per day / 20; HR, 3.0; 95% CI, 1.4-6.5), and complement factor H (CFH) Y402H genotype (CC genotype: HR, 2.3; 95% CI, 1.0-5.3; TC genotype: HR, 1.5; 95% CI, 0.6-3.7). Incidence of early AMD was associated with early AMD in the fellow eye (early AMD1: HR, 2.6; 95% CI, 1.6-4.2; early AMD2: HR, 5.6; 95% CI, 3.3-9.4) and high plasma high-density lipoprotein cholesterol levels (HR, 1.2; 95% CI, 1.0 1.4). Conclusions and Relevance: In this cohort, AMD incidence rates were similar to those observed in other European populations. This study suggests a high risk for incident early AMD in individuals with high plasma high-density lipoprotein cholesterol levels while confirming the high risk for progression from early to advanced AMD in heavy smokers and carriers of CFH Y402H at-risk genotypes. PMID- 29596589 TI - Psychosocial Factors Associated with Problem Drinking Among Substance Users with Poorly Controlled HIV Infection. AB - Aims: We aimed to identify psychosocial factors related to problem drinking among patients with poorly controlled human immunodeficiency virus (HIV) infection. Short Summary: We aimed to identify psychosocial factors related to problem drinking among those with poorly controlled HIV infection. Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician related to excessive drinking. Methods: This secondary analysis used baseline data from a large multisite randomized controlled trial of substance users whose HIV infection was currently poorly controlled, from 11 urban hospitals across the USA. Participants were HIV-infected adult inpatients (n = 801; 67% male, 75% African American) with substance use histories. Participants self-reported on their drinking, perceived health, mental health, social relationships and patient provider relationship. Structural equation models examined psychosocial factors associated with problem drinking, controlling for demographic covariates. Results: Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician were associated with excessive drinking. Conclusions: Several psychosocial factors, including interpersonal conflict, poor mental health (i.e. anxiety, depression and somatization), medical mistrust and less satisfaction with one's provider, were associated with problem drinking among HIV-infected substance users with poorly controlled HIV infection. The co occurrence of these concerns highlights the need for comprehensive services (including attention to problem drinking, social services, mental health and quality medical care) in this at-risk group.

PMID- 29596591 TI - Using electronic maternity records to estimate female genital mutilation in Lothian from 2010 to 2013. AB - Background: Female genital mutilation (FGM) is most commonly encountered in Africa and the Middle East, with migration from FGM-practicing countries meaning it is increasingly seen in Europe. Addressing FGM requires accurate information on who is affected but ascertainment is notoriously difficult. This study estimated FGM prevalence in women presenting for maternity care in the Lothian region of Scotland and compared this with that expected by extrapolation of survey data from women's country of birth. Methods: Electronic clinical records were linked to birth registration data to estimate FGM in the obstetric patients in Lothian from 2010 to 2013. Results: Among all, 107 women affected by FGM were detected, at a rate of 2.8/1000 pregnancies. Of 487 women from UNICEF-recognized FGM-practicing countries who accessed care, 87 (18%) had documented evidence of FGM (three quarters of whom came from Nigeria, Sudan or The Gambia). The prevalence was 54% of the level expected from the extrapolation method. Country of birth had a sensitivity of 81% for FGM. Conclusion: Women from FGM-practicing countries commonly access maternity care in Lothian. This confirms the need for ongoing training and investment in identifying and managing FGM. Matching electronic clinical records with birth registration data was a useful methodology in estimating the level of FGM in the maternity population. In a European country like Scotland with modest migrant numbers, asking country of birth during pregnancy and making sensitive enquiries could detect 81% of women with FGM. Extrapolation from maternal country of birth surveys grossly overestimates the true prevalence. PMID- 29596592 TI - Charter on Physician Well-being.

AB - Background: Human papillomavirus (HPV) vaccination uptake remains lower than other recommended adolescent vaccines in the United States. Parental attitudes are important predictors of vaccine uptake, yet little is known about how they have changed over time. Methods: Participants included US residents aged 13-17 years with documented vaccination status who had received <3 doses of HPV vaccine whose parents responded to the National Immunization Survey-Teen, 2010-2015. Results: Of the 76971 participants, 63.0% were male, 58.8% were non-Hispanic white, and 14.4 years was the median age. The percentage of unvaccinated teens decreased from 2010 to 2015, yet, annually, parents of unvaccinated teens of both sexes most often reported that they were "not likely at all" to vaccinate their teen. The percentage decreased significantly from 41.5% to 31.2% (P < .001) for parents of unvaccinated females from 2010 to 2015 but did not change among parents of males from 2012 to 2015. Conversely, parents of undervaccinated teens of both sexes reported higher and increasing vaccination intent over time. In 2015, nearly one-third of parents of unvaccinated teens reported that the vaccine was "not needed/necessary." Concerns about vaccine safety and side effects declined among parents of unvaccinated females but increased among parents of males (7.3% to 14.8%; P < .001). Conclusions: Although parental vaccination intent and knowledge improved over time, intent remains low and many parents still have significant concerns about HPV vaccination, even after series initiation. Multiple strategies are needed to improve series initiation and completion in the United States.

PMID- 29596597 TI - Rehabilitation Exercise Increases Physical Activity Levels in Severely Burned Children While Improving Aerobic Exercise Capacity and Strength. AB - This study tested the hypothesis that participation in a rehabilitation exercise program following hospital discharge would increase the level of physical activity in burned children than that seen in free-living nonburned children. Thirty-one severely burned children (12 +/- 3 years, 144 +/- 18 cm, 42 +/- 17 kg, 48 +/- 12% TBSA burns) were matched to 31 nonburned children (12 +/- 3 y, 147 +/- 17 cm, 45 +/- 15 kg) based on age and sex. Pedometers were used to track minutes and steps in burned children during their exercise rehabilitation and nonburned children under free-living conditions (healthy control). We found that the average minutes of activity per day was lower in burned children (56 +/- 25minutes) than in nonburned children (74 +/- 28 minutes, P < .05). However, no difference was detected for average steps per day or week or maximal minutes in 1 day or week. At discharge, burn children had peak torque and mean power values that were 61% of nonburned values, and exercise training improved these by 27 and 28%, respectively (88 and 89% of nonburned values; each P <= .0001). Likewise, cardiorespiratory fitness at discharge was 72% of nonburned values, and exercise training improved fitness by 10% (82% of nonburned values, P < .05). Percentage TBSA burned was inversely associated with steps (r = -0.54, P = .001) and minutes of activity (r = -0.53, P = .002), accounting for 28-29% of the variability in burned children. These results show that, at discharge, burned children are capable of matching steps of physical activity levels seen in nonburned healthy children. Physical activity monitoring may be a viable option for continued improvement of physical exercise capacity when burned children are under free living conditions. PMID- 29596598 TI - A survey of practice and opinions on the use of topical antibiotics to prevent surgical site infection: more confusion than consensus. AB - Background: Surgical site infection (SSI) is one of the most common causes of healthcare-associated infection. Although the use of topical antibiotics to prevent SSI is not recommended by current guidelines, published studies document conflicting results and conclusions. Objectives: The objectives of this survey were to: (i) determine the extent of the use of topical antibiotics to prevent SSI in clinical practice; and (ii) gather the opinions of healthcare professionals most likely to be involved in their use. Methods: A questionnaire was circulated to members of BSAC and the European Wound Management Association (EWMA). Results: The questionnaire received 160 responses from a variety of healthcare professionals around the world. Most respondents (70%) did not have guidelines for the use of topical antibiotics for the prevention of SSI in their institution; if present, local guidance was based on national guidelines (20/31, 65%). Most respondents did not use or recommend topical antibiotics to prevent SSI; of those that did, gentamicin collagen sponges were most commonly used (24/96 responses, 25%). Over half of the surgeons (18/33, 55%) who responded to the survey did not use topical antibiotics for the prevention of SSI but, when used, contaminated surgery (8/33, 24%) was the most commonly stated indication. Conclusions: There are diverse opinions and practices among healthcare professionals about the use of topical antibiotics for the prevention of SSI. This considerable, and possibly inappropriate, variation in clinical practice needs to be addressed as part of antibiotic stewardship.

PMID- 29596600 TI - Burn Scar Evaluation Using the Cutometer(r) MPA 580 in Comparison to "Patient and Observer Scar Assessment Scale" and "Vancouver Scar Scale". AB - The effect of the "Patient and Observer Scar Assessment Scale" (POSAS) and "Vancouver Scar Scale" (VSS) on patients' quality of life and their correlation with objective scar assessment tools, such as the Cutometer(r), is not fully elucidated. In addition, long-term results of the dermal substitute Matriderm(r) used in combination with split-thickness skin grafting (STSG) remain unclear. We evaluated burn scars of 45 patients at least 2 years postburn injury using the Cutometer(r) MPA 580, the VSS, and the POSAS with three additional questions regarding quality of life and correlated the results. Study groups were: 1) scars following conservative treatment, 2) scars following STSG, and 3) scars following STSG in combination with Matriderm(r). Cutometer(r) measurements demonstrated better elastic qualities in the Matriderm(r) group compared with the STSG group. VSS and extended POSAS were rated best for the conservative group, followed by the STSG group and the Matriderm(r) group. There was a significant correlation between POSAS and VSS, quality of life and the objective Cutometer(r) measurements. Conservatively treated superficial dermal burns do not reach the elastic qualities of healthy skin, and the use of Matriderm(r) significantly improves the long-term elastic qualities of STSG in deep dermal and full thickness burns 2 years post injury. Results from the VSS and the POSAS correlate with restrictions in the quality of life of patients and also with objective Cutometer(r) measurements and are therefore useful tools in scar evaluation following burn injury. PMID- 29596601 TI - Response to Escobedo et al. PMID- 29596602 TI - Radiation of Bactrocera dorsalis (Diptera: Tephritidae) Eggs to Improve the Mass Rearing of Diachasmimorpha longicaudata (Hymenoptera: Braconidae). AB - This study explored the potential for Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) larvae hatched from irradiated eggs as hosts for Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae). B. dorsalis eggs of three different ages (12-, 24-, and 36-h old) were analyzed for hatchability, pupation rate, pupal weight, emergence rate, and sex ratio after exposure to different doses of radiation (5 and 10 Gy) at different dose rates (1 and 6 Gy/min). For the eggs of different ages exposed to radiation, only the hatchability and pupal weight of 36-h-old eggs exposed to the dose rate of 1 Gy/min were not affected; therefore, 6 Gy/min was not suitable for irradiating eggs. The viability of the parents and progenies of D. longicaudata when the parents were reared from 36-h old eggs irradiated at nine different doses (0, 5, 10, 15, 20, 25, 30, 35, and 40 Gy) under laboratory conditions were investigated. The emergence percentage, sex ratio, and longevity of parasitoids developed from irradiated eggs were similar to those reared from nonirradiated hosts. A significant increase in larva mortality was observed for the eggs irradiated at doses above 25 Gy, and no redundant adult flies emerged at doses above 15 Gy. Hence, for B. dorsalis eggs to be applied in the mass rearing of D. longicaudata, the age of 36 h and a dose of 20-25 Gy are the optimal parameters. The results reveal that hosts and parasitoids need not be separated, enabling a reduction in cost, labor, and time and resulting in an improved mass rearing procedure for D. longicaudata. PMID- 29596603 TI - A Declaration of Independence: Implicit Alcohol Associations Have Independent, not Interactive, Relationships with Alcohol Consumption and AUD Risk. AB - Aims: The current study aimed to test for potential interactive effects of three implicit alcohol-related associations (drinking identity, alcohol approach and alcohol excitement) in predicting concurrent and prospective alcohol consumption and risk of alcohol use disorders (AUDs) in two samples of the US undergraduate drinkers and non-drinkers. Short summary: We investigated the independent and interactive effects of three implicit associations on alcohol consumption and risk of AUD in two US undergraduate student samples. We found that implicit associations had independent but not interactive effects on concurrent and subsequent alcohol consumption and risk of AUD in two independent samples. Methods: Implicit drinking identity, alcohol approach and alcohol excitement associations were assessed in two US undergraduate student samples (Sample 1: N = 300, 55% female; Sample 2: N = 506, 57% female). Alcohol consumption and risk of AUD were assessed at baseline (Samples 1 and 2) and 3 months later (Sample 2). We fit zero-inflated negative binomial models to test for independent and interactive effects of the three implicit associations on alcohol consumption and risk of AUD. Results: Although we found multiple, unique main effects for alcohol associations, we found minimal evidence of interactions between implicit alcohol related associations. There was no reliable evidence of interactions in models in predicting alcohol consumption or risk of AUD, concurrently or prospectively, in either sample. Conclusions: Contrary to expectations, results from both studies indicated that implicit alcohol-related associations in the US undergraduate samples generally have independent, not interactive, relationships with alcohol consumption and risk of AUD. PMID- 29596604 TI - A structurally conserved motif in gamma-herpesvirus uracil-DNA glycosylases elicits duplex nucleotide-flipping. AB - Efficient gamma-herpesvirus lytic phase replication requires a virally encoded UNG-type uracil-DNA glycosylase as a structural element of the viral replisome. Uniquely, gamma-herpesvirus UNGs carry a seven or eight residue insertion of variable sequence in the otherwise highly conserved minor-groove DNA binding loop. In Epstein-Barr Virus [HHV-4] UNG, this motif forms a disc-shaped loop structure of unclear significance. To ascertain the biological role of the loop insertion, we determined the crystal structure of Kaposi's sarcoma-associated herpesvirus [HHV-8] UNG (kUNG) in its product complex with a uracil-containing dsDNA, as well as two structures of kUNG in its apo state. We find the disc-like conformation is conserved, but only when the kUNG DNA-binding cleft is occupied. Surprisingly, kUNG uses this structure to flip the orphaned partner base of the substrate deoxyuridine out of the DNA duplex while retaining canonical UNG deoxyuridine-flipping and catalysis. The orphan base is stably posed in the DNA major groove which, due to DNA backbone manipulation by kUNG, is more open than in other UNG-dsDNA structures. Mutagenesis suggests a model in which the kUNG loop is pinned outside the DNA-binding cleft until DNA docking promotes rigid structuring of the loop and duplex nucleotide flipping, a novel observation for UNGs. PMID- 29596605 TI - Evaluation of voriconazole anti-Acanthamoeba polyphaga in vitro activity, rat cornea penetration and efficacy against experimental rat Acanthamoeba keratitis. AB - Background: Acanthamoeba keratitis (AK) is a sight-threatening infectious disease. Its effective and safe medical therapy remains highly debated. Recently, voriconazole, a monotriazole with noted in vitro activity against a large variety of fungi, has been successfully used both topically and systemically to treat human AK cases. Objectives: To measure anti-Acanthamoeba polyphaga in vitro activity, anti-rat AK efficiency and rat cornea penetration of eye-drop and oral voriconazole. Methods: A. polyphaga was maintained in axenic cultures. In vitro, amoebicidal and cysticidal activities of voriconazole were measured using an XTT assay. AK lesions of Sprague Dawley rats were scored from grade 0 to grade 3. For 21 days, from day 7 post-infection, voriconazole (1% solution) eye drops were instilled or voriconazole was administered by gavage (60 mg/kg/day). After killing, superficial corneal epithelium scrapings were cultured and analysed by PCR, and eye-globe histology was performed. Cornea and plasma concentrations were determined using 2D HPLC separation and tandem MS. Results: In vitro, voriconazole inhibited trophozoite proliferation with an IC50 value of 0.02 mg/L and an IC90 value of 2.86 mg/L; no cysticidal effect was found. In AK rats, eye drops reduced clinical worsening from day 7 to day 14 post-infection and oral voriconazole was not effective. Voriconazole cornea concentrations were directly dependent on the frequency of eye-drop instillations, which resulted in lower plasma concentrations, whilst oral voriconazole resulted in lower cornea concentrations. Conclusions: Present data underline the need for high-frequency eye-drop instillation regimens for efficient AK therapy. PMID- 29596606 TI - Menopausal Hormone Therapy Is Associated With Reduced Total and Visceral Adiposity: The OsteoLaus Cohort. AB - Context: After menopause, fat mass (FM) and visceral adipose tissue (VAT) increase and nonbone lean body mass (LBM) decreases. Whether menopausal hormone therapy (MHT) reverses these changes remains controversial. Objective: To assess the effect of MHT on FM, VAT, and LBM before and after its withdrawal and evaluate potential confounders. Design: Cross-sectional study. Setting: General community. Patients or Other Participants: Women of the OsteoLaus cohort (50 to 80 years old) who underwent dual-energy X-ray absorptiometry (DXA) with body composition assessment. After we excluded women with estrogen-modifying medications, the 1053 participants were categorized into current users (CUs), past users (PUs), and never users (NUs) of MHT. Intervention: None. Main Outcome Measures: VAT measured by DXA was the primary outcome. We assessed subtotal and android FM, LBM, muscle strength (hand grip), and confounding factors (caloric intake, physical activity, biomarkers). Results: The groups significantly differed in age, NU < CU < PU. Age-adjusted VAT was lower in CUs than NUs (P = 0.03). CUs exhibited lower age-adjusted body mass index (BMI) (-0.9 kg/m2) and a trend for lower FM (-1.3 kg). The 10-year gain of VAT (P < 0.01) and subtotal and android FM (P < 0.05) was prevented in CUs. No difference in LBM or hand grip was detected. No residual effect was detected for PUs, including for early MHT discontinuers. The confounding factors did not significantly differ between groups except for higher caloric intake in PUs compared with NUs. Conclusions: MHT is associated with significantly decreased VAT, BMI, and android FM. No benefit is detected for LBM. The benefits are not preserved in PUs, suggesting caution when MHT is discontinued. PMID- 29596607 TI - Workplace Respiratory Protection Factors during Asbestos Removal Operations. AB - Numerous changes have been made to the French labour regulations in recent years relating to the prevention of risks of exposure to asbestos fibres for operators removing asbestos-containing materials. These changes refer to the method used to count fibres, the collective and personal protective devices to be used on these worksites, and the occupational exposure limit value, which was reduced to 10 f.L 1 on 2 July 2015. In this context, this study assessed the level of respiratory protection afforded by supplied-air respirators and powered air-purifying respirators by monitoring exposure for several operators on nine worksites. The levels of dustiness measured in personal samples taken outside masks showed significant evidence of potential exposure during removal of asbestos-containing plaster or sprayed asbestos, and when using abrasive blasting to treat asbestos containing materials. For these tasks outside concentration regularly exceeds 25000 f.L-1. Measurements inside masks were generally low, under 10 f.L-1, except in some situations involving the removal of asbestos-containing plaster. This partial penetration of fibres inside masks could be due to the high loading linked to this material. The distributions of Workplace Protection Factors obtained for the two types of respiratory protective devices studied were broad, and the fifth percentile values equal to 236 and 104, respectively, for supplied air respirators and powered air-purifying respirators. This work highlights once again the need to prioritize collective protection when seeking to prevent asbestos-related risks. PMID- 29596608 TI - SimPhospho: a software tool enabling confident phosphosite assignment. AB - Motivation: Mass spectrometry combined with enrichment strategies for phosphorylated peptides has been successfully employed for two decades to identify sites of phosphorylation. However, unambiguous phosphosite assignment is considered challenging. Given that site-specific phosphorylation events function as different molecular switches, validation of phosphorylation sites is of utmost importance. In our earlier study we developed a method based on simulated phosphopeptide spectral libraries, which enables highly sensitive and accurate phosphosite assignments. To promote more widespread use of this method, we here introduce a software implementation with improved usability and performance. Results: We present SimPhospho, a fast and user-friendly tool for accurate simulation of phosphopeptide tandem mass spectra. Simulated phosphopeptide spectral libraries are used to validate and supplement database search results, with a goal to improve reliable phosphoproteome identification and reporting. The presented program can be easily used together with the Trans-Proteomic Pipeline and integrated in a phosphoproteomics data analysis workflow. Availability and implementation: SimPhospho is open source and it is available for Windows, Linux and Mac operating systems. The software and its user's manual with detailed description of data analysis as well as test data can be found at https://sourceforge.net/projects/simphospho/.

PMID- 29596609 TI - From Bedside to Bench: The Effect of Muscular Denervation on Fat Grafting to the Breast by Comparing Take Rate, Quality, and Longevity. AB - Background: Autologous fat grafting (AFG) to the breast is a frequent procedure in aesthetic and reconstructive surgery. Despite pure volume gain, questions remain regarding the engraftment rate, quality, and longevity. Little is known about the role of recipient tissue or innervation of the grafted area. Objectives: The goal of this study was to determine the optimal recipient layer and muscular pretreatment of AFG. Methods: Fat was grafted to the breast, pectoralis muscle, or adjacent subcutaneous tissue of 42 rats. Nerve treatment included excision of a nerve segment, botulinum toxin (BTX) injection, or no treatment. Magnetic resonance imaging (MRI) and histological workup were carried out after 2 and 6 weeks. Results: Six weeks after AFG, the proportion of viable fat cells within the grafted fat stayed high (median, [IQR]: 81% [72% to 85%]). The signs of inflammation decreased over time. Intramuscular grafting with intact nerves had a decreasing effect on the viability of the grafted cells compared with subcutaneous treatment (-10.21%; 95% confidence interval [-21.1 to 0.68]). Conclusions: If utilized on an intact nerve, intramuscular injection may lead to inferior results. If the nerve was cut or treated with BTX; however, intramuscular injection tends to be superior. These findings may prove interesting for future studies and eventual clinical application. PMID- 29596610 TI - Multiple coronary artery fistulae in a young man. PMID- 29596611 TI - Comparison of Frankliniella fusca and Frankliniella occidentalis (Thysanoptera: Thripidae) as Vectors for a Peanut Strain of Tomato Spotted Wilt Orthotospovirus. AB - Tomato spotted wilt orthotospovirus (TSWV) is a major disease in peanut, Arachis hypogaea L., across peanut producing regions of the United States and elsewhere. Two thrips, Frankliniella fusca Hinds and Frankliniella occidentalis Pergande (Thysanoptera: Thripidae), are considered important vectors of TSWV in peanut in the Southeast. We compared the efficiency of acquisition (by larvae) and transmission (adults) of both thrips species for TSWV (Texas peanut-strain) to leaf disks of peanut (Florunner), as well as to Impatiens walleriana Hook. f. (Dwarf White Baby) and Petunia hybrida Juss. 'Fire Chief' using double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). Both species were competent TSWV vectors in peanut and Impatiens, although F. fusca was the more efficient vector overall, i.e., virus acquisition and transmission rates for F. fusca averaged over several bioassays were 51.7 and 26.6%, respectively, compared with 20.0 and 15.3% for F. occidentalis. Neither species effectively transmitted this TSWV strain to Petunia (i.e., <=3.6% transmission). We found statistically similar virus acquisition and transmission rates between both sexes for each species. We also detected no differences in TSWV-acquisition and transmission frequency between macropterous and brachypterous (short-wing) forms of F. fusca collected from a field population in south Texas. DAS-ELISA failed to detect low levels of TSWV in a few thrips that subsequently proved to be competent vectors. PMID- 29596613 TI - Repeat left ventricular assist device exchange with inflow or outflow correction for recurrent pump thrombosis and cerebral haemorrhage through limited incisions. AB - Left ventricular assist devices (LVADs) may require subsequent pump exchange due to device thrombosis or thromboembolism. A limited left thoracotomy may offer advantages over standard full sternotomy in redo procedures by preserving pristine median access and decreasing the potential for re-entry injuries, postoperative bleeding and transfusion requirements. We describe repeat LVAD exchange via the left limited thoracotomy with outflow graft anastomosis to the left subclavian artery with the correction of LVAD inflow cannula angulation following recurrent LVAD thromboses. PMID- 29596612 TI - Burn Injury May Have Age-Dependent Effects on Strength and Aerobic Exercise Capacity in Males. AB - Whether burn injury affects boys and men differently is currently unknown. To test the hypothesis that burned boys have lower exercise capacity and exercise training-induced responses compared with burned men, 40 young boys (12 +/- 4 years, 149 +/- 20 cm, 46 +/- 18 kg) were matched to 35 adult men (33 +/- 9 years, 174 +/- 10 cm, 84 +/- 16 kg) based on extent of burn injury (total body surface area burned, boys 46 +/- 14% vs men 47 +/- 30, P = .85) and length of hospital stay (boys 33 +/- 23 vs men 41 +/- 32 days, P = .23). Strength (peak torque) and cardiorespiratory fitness (peak VO2) were normalized to kg of lean body mass for group comparisons. Each group was also compared with normative age-sex matched values at discharge and after an aerobic and resistance exercise training (RET) program. A two-way factorial analysis of covariance assessed interaction and main effects of group and time. We found that boys and men showed similar pre-RET to post-RET increases in total lean (~4%) and fat (7%) mass (each P <= .008). Both groups had lower age-sex matched norm values at discharge for peak torque (boys 36%; men 51% of normative values) and peak VO2 (boys: 44; men: 59%; each P <= .0001). Boys strength were 13-15 per cent lower than men at discharge and after RET (main effect for group, P < .0001). Cardiorespiratory fitness improved to a greater extent in men (19%) compared with boys (10%) after the RET (group * time interaction, P = .011). These results show that at discharge and after RET, burn injury may have age-dependent effects and should be considered when evaluating efficacy and progress of the exercise program. PMID- 29596614 TI - Trials and tribulations: cross-learning from the practices of epidemiologists and economists in the evaluation of public health interventions. AB - The randomized controlled trial is commonly used by both epidemiologists and economists to test the effectiveness of public health interventions. Yet we have noticed differences in practice between the two disciplines. In this article, we propose that there are some underlying differences between the disciplines in the way trials are used, how they are conducted and how results from trials are reported and disseminated. We hypothesize that evidence-based public health could be strengthened by understanding these differences, harvesting best-practice across the disciplines and breaking down communication barriers between economists and epidemiologists who conduct trials of public health interventions.

PMID- 29596616 TI - VEGF and VEGFB Play Balancing Roles in Adipose Differentiation, Gene Expression, and Function. AB - Obesity is the result of abnormal adipose development and energy metabolism. Using vascular endothelial growth factor (VEGF) B-knockout and inducible VEGF downregulation mouse models, we have shown that VEGFB inactivation caused expansion of white adipose, whitening of brown adipose, an increase in fat accumulation, and a reduction in energy consumption. At the same time, expression of the white adipose-associated genes was increased and brown adipose-associated genes decreased. VEGF repression, in contrast, induced brown adipose expansion and brown adipocyte development in white adipose, increased energy expenditure, upregulated brown adipose-associated genes, and downregulated white adipose associated genes. When VEGFB-knockout and VEGF-repressed mice are crossed together, VEGF and VEGFB can counteractively regulate large numbers of genes and efficiently reverse each other's roles. These genes, under counteractive VEGF and VEGFB regulations, include transcription factors, adhesion molecules, and metabolic enzymes. This balancing role is confirmed by morphologic and functional changes. This study reports that VEGF and VEGFB counteractively regulate adipose development and function in energy metabolism. PMID- 29596617 TI - Association of Trajectories of Higher-Level Functional Capacity with Mortality and Medical and Long-Term Care Costs Among Community-Dwelling Older Japanese. AB - Background: Higher-level functional capacity is crucial component for independent living in later life. We used repeated-measures analysis to identify aging trajectories in higher-level functional capacity. We then determined whether these trajectories were associated with all-cause mortality and examined differences in medical and long-term care costs between trajectories among community-dwelling older Japanese. Methods: 2,675 adults aged 65-90 years participated in annual geriatric health assessments and biennial health monitoring surveys during the period from October 2001 through August 2011. The average number of follow-up assessments was 4.0, and the total number of observations was 10,609. Higher-level functional capacity, which correspond to the fourth and fifth sublevels of Lawton's hierarchical model, was assessed with the Tokyo Metropolitan Institute of Gerontology-Index of Competence (TMIG-IC). Results: We identified four distinct trajectory patterns (high-stable, late-onset decreasing, early-onset decreasing, and low-decreasing) on the TMIG-IC through age 65-90 years. As compared with the high-stable trajectory group, participants in the late-onset decreasing, early-onset decreasing, and low-decreasing TMIG-IC trajectory groups had adjusted hazard ratios for mortality of 1.22 (95% confidence interval: 1.01-1.47), 1.90 (1.53-2.36), and 2.87 (2.14-3.84), respectively. Participants with high-stable and late-onset decreasing higher level functional capacity trajectories had lower mean monthly medical costs and long-term care costs. In contrast, mean total costs were higher for those with low-decreasing trajectories, after excluding the large increase in such costs at the end of life. Conclusions: People with a low-decreasing aging trajectory in higher-level functional capacity had higher risks of death and had high monthly total costs.

PMID- 29596618 TI - Patterns in Health Care Access and Affordability Among Cancer Survivors During Implementation of the Affordable Care Act. AB - Importance: Cancer survivors face ongoing health issues and need access to affordable health care, yet studies examining health care access and affordability in this population are lacking. Objectives: To evaluate health care access and affordability in a national sample of cancer survivors compared with adults without cancer and to evaluate temporal trends during implementation of the Affordable Care Act. Design, Setting, and Participants: We used data from the National Health Interview Survey from 2010 through 2016 to conduct a population based study of 30 364 participants aged 18 years or older. We grouped participants as cancer survivors (n = 15 182) and those with no reported history of cancer, whom we refer to as control respondents (n = 15 182), matched on age. We excluded individuals reporting a cancer diagnosis prior to age 18 years and those with nonmelanoma skin cancers. Main Outcomes and Measures: We compared issues with health care access (eg, delayed or forgone care) and affordability (eg, unable to afford medications or health care services) between cancer survivors and control respondents. We also explored trends over time in the proportion of cancer survivors reporting these difficulties. Results: Of the 30 364 participants, 18 356 (57.4%) were women. The mean (SD) age was 63.5 (23.5) years. Cancer survivors were more likely to be insured (14 412 [94.8%] vs 13 978 [92.2%], P < .001) and to have government-sponsored insurance (7266 [44.3%] vs 6513 [38.8%], P < .001) compared with control respondents. In multivariable models, cancer survivors were more likely than control respondents to report delayed care (odds ratio [OR], 1.38; 95% CI, 1.16-1.63), forgone medical care (OR, 1.76; 95% CI, 1.45-2.12), and/or inability to afford medications (OR, 1.77; 95% CI, 1.46-2.14) and health care services (OR, 1.46; 95% CI, 1.27-1.68) (P < .001 for all). From 2010 to 2016, the proportion of survivors reporting delayed medical care decreased each year (B = 0.47; P = .047), and the proportion of those needing and not getting medical care also decreased each year (B = 0.35; P = .04). In addition, the proportion of cancer survivors who reported being unable to afford prescription medication decreased each year (B=0.66; P = .004) and the proportion of those unable to afford at least 1 of 6 services decreased each year (B = 0.51; P = .01). Conclusions and Relevance: Despite higher rates of insurance coverage, cancer survivors reported greater difficulties accessing and affording health care compared with adults without cancer. Importantly, the proportion of survivors reporting these issues continued a downward trend throughout our observation period in the years following the implementation of the Affordable Care Act. Our findings suggest incremental improvement in health care access and affordability after recent health care reform and provide an important benchmark as additional changes are likely to occur in the coming years.

AB - Matrix-embedded, surface-attached microbial communities, known as biofilms, profusely colonise industrial cooling water systems, where the availability of nutrients and organic matter favours rapid microbial proliferation and their adhesion to surfaces in the evaporative fill material, heat exchangers, water reservoir and cooling water sections and pipelines. The extensive growth of biofilms can promote micro-biofouling and microbially induced corrosion (MIC) as well as pose health problems associated with the presence of pathogens like Legionella pneumophila. This review examines critically biofilm occurrence in cooling water systems and the main factors potentially affecting biofilm growth, biodiversity and structure. A broad evaluation of the most relevant biofilm monitoring and control strategies currently used or potentially useful in cooling water systems is also provided.

PMID- 29596623 TI - So Close and Yet So Irritating: Negative Relations and Implications for Well being by Age and Closeness. AB - Objectives: Negative social relationships are associated with poor health, chronic illness, and mortality. Yet, we know little about the dynamics of negative aspects of relationships within individual's closest relationships over time, how those experiences vary by age, and the implications of those relationships for well-being. Method: A total of 592 participants (ages 25 to 97; M= 57.5; 63.3% women) from the Social Relations Study completed monthly web surveys for up to 12 months. Each month they reported negative relationship quality with their three closest network members and multiple dimensions of well being (positive affect, negative affect, self-rated health, and sleep quality). Results: Multilevel models revealed older individuals reported less negativity in their relationships than younger people, but fewer age differences in the closest tie. Greater negative relationship quality predicted poor well-being (i.e., greater negative affect, sleep problems). Links between negative relations and well-being were less strong among older individuals; especially in the closest ties. Discussion: Results were partially consistent with the strength and vulnerability integration (SAVI) model, which proposes fewer age-related improvements in emotion regulation when individuals are unable to avoid tensions. Despite feeling just as negative as younger individuals, older individuals may be more resilient to tensions in their closest relationships.

PMID- 29596625 TI - Can we address cancer disparities in immigrants by improving cancer literacy through English as a second language instruction? AB - In many Western countries, immigrants exhibit disparities in cancer incidence and mortality, and variable uptake of cancer prevention services. New immigrants may not be aware of cancer risks pertinent to their new country, or prevention resources. Traditional cancer prevention health messaging may not be accessible for cultural, language, or literacy reasons. New methods are needed. In North America, health message delivery via English classes for immigrants is showing potential as an efficacious and a feasible way to reach immigrants at the same time improving language skills. Interventions published to date are promising but limited in their ability to generalize or be adapted to a variety of populations and settings. This concept paper aims to synthesize previous findings and identify ways to improve and advance the translation potential of this approach. We propose that this could be achieved by (i) using a translation framework to guide intervention planning, development, implementation, and evaluation; (ii) encouraging and evaluating health message spread throughout language learners' social networks; and (iii) incorporating cultural sensitivity into the curriculum. A pilot project following these recommendations is planned for Australia and will be discussed. These recommendations could serve as a framework to fit the requirements of immigrant language programs in other countries and other health topics.

PMID- 29596627 TI - A Putative Insulin-like Androgenic Gland Hormone Receptor Gene Specifically Expressed in Male Chinese Shrimp. AB - The insulin-like androgenic gland hormone (IAG) is the key regulator in crustacean male sexual differentiation. As a secreted peptide hormone, IAG might perform its biological function through interacting with the membrane receptor. However, the receptor of IAG remains unclear. In the current study, a putative IAG receptor gene (FcIAGR) was identified in Fenneropenaeus chinensis. The deduced amino acid sequence of FcIAGR contained several conserved domains of insulin-like receptor proteins, including two L domains (L1 and L2), a cysteine rich domain, three fibronectin III domains, a transmembrane domain, and an intracellular tyrosine kinase domain. Tissue distribution and in situ hybridization analysis showed that FcIAGR was predominantly expressed in the androgenic gland and testis in male F. chinensis. Protein colocalization analysis in HEK293 cells showed that FcIAGR could colocalize with both FcIAG1 and FcIAG2, respectively. Yeast two-hybrid assay further confirmed the interactions between FcIAGR and FcIAGs. After a long-term silencing of FcIAGR with double-stranded RNA, most of the germ cells in the testis were arrested at the secondary spermatocytes, whereas those in the control developed into sperm cells. The data indicated that FcIAGR was the receptor of FcIAGs in F. chinensis. The current study provides insight into the mechanism that the insulin-like signaling pathway regulates the male sexual differentiation in Decapoda crustaceans. PMID- 29596628 TI - The quantitative models for broiler chicken response to monochromatic, combined, and mixed light-emitting diode light: A meta-analysis. AB - Although many experiments have been conducted to clarify the response of broiler chickens to light-emitting diode (LED) light, those published results do not provide a solid scientific basis for quantifying the response of broiler chickens. This study used a meta-analysis to establish light spectral models of broiler chickens. The results indicated that 455 to 495 nm blue LED light produced the greatest positive response in body weight by 10.66% (BW; P < 0.001) and 515 to 560 nm green LED light increased BW by 6.27% (P < 0.001) when compared with white light. Regression showed that the wavelength (455 to 660 nm) was negatively related to BW change of birds, with a decrease of about 4.9% BW for each 100 nm increase in wavelength (P = 0.002). Further analysis suggested that a combination of the two beneficial light sources caused a synergistic effect. BW was further increased in birds transferred either from green LED light to blue LED light (17.23%; P < 0.001) or from blue LED light to green LED light (17.52%; P < 0.001). Moreover, birds raised with a mixture of green and blue LED light showed a greater BW promotion (10.66%; P < 0.001) than those raised with green LED light (6.27%). A subgroup analysis indicated that BW response to monochromatic LED light was significant regardless of the genetic strain, sex, control light sources, light intensity and regime of LED light, environmental temperature, and dietary ME and CP (P > 0.05). However, there was an interaction between the FCR response to monochromatic LED light with those covariant factors (P < 0.05). Additionally, green and yellow LED light played a role in affecting the meat color, quality, and nutrition of broiler chickens. The results indicate that the optimal ratio of green * blue of mixed LED light or shift to green-blue of combined LED light may produce the optimized production performance, whereas the optimal ratio of green/yellow of mixed or combined LED light may result in the optimized meat quality.

AB - The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR associated protein 9 (Cas9) system is an efficient and rapid tool for genome editing. However, its utilization in bacteria suffers challenges such as the risk of repeated recognition and cutting by Cas9. Here we established a two-step genome editing strategy using the Streptococcus pyogenes CRISPR-Cas9 system to achieve a clean mutation with only the target sites into the Escherichia coli genome. This strategy can avoid the risk of repeated cutting by guide RNA (gRNA)/Cas9 without altering the protospacer-adjacent motif or inserting additional silent mutations into the genome. The principles and approaches we developed in this study can be applied to modify coding and non-coding sequences in essential and non-essential genes and can also be used for precise genome editing in other microorganisms.

AB - Patients' ability to access their provider's clinical notes (OpenNotes) has been well received and has led to greater transparency in health systems. However, the majority of this research has occurred in primary care, and little is known about how patients' access to notes is used in oncology. This study aims to understand oncologists' perceptions of OpenNotes, while also establishing a baseline of the linguistic characteristics and patterns used in notes.Data from 13 in-depth, semistructured interviews with oncologists were thematically analyzed. In addition, the Linguistic Inquiry and Word Count (LIWC) program evaluated over 200 clinician notes, measuring variables encompassing emotions, thinking styles, social concerns, and parts of speech. Analysis from LIWC revealed that notes contained negative emotional tone, low authenticity, high clout, and high analytical writing. Oncologists' use of stigmatized and sensitive words, such as "obese" and "distress," was mainly absent. Themes from interviews revealed that oncologists were uncertain about patients' access to their notes and may edit their notes to avoid problematic terminology. Despite their reluctance to embrace OpenNotes, they envisioned opportunities for an improved patient-provider relationship due to patients initiating interactions from viewing notes.Oncologists believe notes are not intended for patients and altering their content may compromise the integrity of the note. This study established a baseline for further study to compare notes pre-implementation to post implementation. Further analysis will clarify whether oncologists are altering the style and content of their notes and determine the presence of patient centered language. PMID- 29596634 TI - Expression and purification of biologically active recombinant rabbit monocyte chemoattractant protein1 in Escherichia coli. AB - Monocyte chemoattractant protein 1 (MCP1) with recruiting monocytes is an important factor at the beginning of inflammatory disorders such as atherosclerosis which seems its blocking preclude this process and help improvement of related diseases. To perform clinical research in this field, MCP1 protein is required but firstly, animal studies should be done. As the rabbit is a suitable model for many inflammatory disorders, and Escherichia coli BL21(DE3) (BL21) cell is a high-efficiency host for protein expression, we decided to produce recombinant rabbit MCP1 (rRMCP1) in BL21/pET28a system. After codon usage, a construct containing RMCP1 sequence was synthesized, cloned into the pET28a plasmid, and overexpressed in BL21 cells. Followed that, with changing expression condition such as cell concentration before the induction, time period, temperature, shaking rate and inducer concentration (IPTG), rRMCP1 expression was optimized, and purified by Ni-NTA. The biological activity of the expressed protein was verified using monocyte migration assay. Using this expression system, nearly 28 mg/mL rRMCP1 was produced at 26 degrees C/180 rpm for 24 h in LB broth medium with 1 mM IPTG. Therefore, we were succeeded to express the intermediate level of rRMCP1 with this method. This amount of protein is sufficient for biological researches in the laboratory.

PMID- 29596635 TI - Tiny architects: biogenesis of intracellular replicative niches by bacterial pathogens. AB - Co-evolution of bacterial pathogens with their hosts led to the emergence of a stunning variety of strategies aiming at the evasion of host defences, colonisation of host cells and tissues and, ultimately, the establishment of a successful infection. Pathogenic bacteria are typically classified as extracellular and intracellular; however, intracellular lifestyle comes in many different flavours: some microbes rapidly escape to the cytosol whereas other microbes remain within vacuolar compartments and harness membrane trafficking pathways to generate their host-derived, pathogen-specific replicative niche. Here we review the current knowledge on a variety of vacuolar lifestyles, the effector proteins used by bacteria as tools to take control of the host cell and the main membrane trafficking signalling pathways targeted by vacuolar pathogens as source of membranes and nutrients. Finally, we will also discuss how host cells have developed countermeasures to sense the biogenesis of the aberrant organelles harbouring bacteria. Understanding the dialogue between bacterial and eukaryotic proteins is the key to unravel the molecular mechanisms of infection and in turn, this may lead to the identification of new targets for the development of new antimicrobials.

AB - Objectives: Chronic non-bacterial osteomyelitis (CNO) or chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder characterized by sterile bone osteolytic lesions. The aim of this study was to evaluate the demographic data and clinical, instrumental and therapeutic features at baseline in a large series of CNO/CRMO patients enrolled in the Eurofever registry. Methods: A web-based registry collected retrospective data on patients affected by CRMO/CNO. Both paediatric and adult centres were involved. Results: Complete baseline information on 486 patients was available (176 male, 310 female). The mean age of onset was 9.9 years. Adult onset (>18 years of age) was observed in 31 (6.3%) patients. The mean time from disease onset to final diagnosis was 1 year (range 0-15). MRI was performed at baseline in 426 patients (88%), revealing a mean number of 4.1 lesions. More frequent manifestations not directly related to bone involvement were myalgia (12%), mucocutaneous manifestations (5% acne, 5% palmoplantar pustulosis, 4% psoriasis, 3% papulopustular lesions, 2% urticarial rash) and gastrointestinal symptoms (8%). A total of 361 patients have been treated with NSAIDs, 112 with glucocorticoids, 61 with bisphosphonates, 58 with MTX, 47 with SSZ, 26 with anti-TNF and 4 with anakinra, with a variable response. Conclusion: This is the largest reported case series of CNO patients, showing that the range of associated clinical manifestations is rather heterogeneous. The study confirms that the disease usually presents with an early teenage onset, but it may also occur in adults, even in the absence of mucocutaneous manifestations. PMID- 29596639 TI - The BODY-Q Stretch Marks Scale: A Development and Validation Study. AB - Background: Stretch marks are common permanent dermal lesions that can cause psychosocial distress. A number of treatment modalities are available, with the majority targeted towards collagen production. Objectives: To develop and field test a new BODY-Q scale to measure appearance of stretch marks in order to provide a means to incorporate the patient perspective into future treatment studies. Methods: We previously described the development of the BODY-Q conceptual framework, which involved a literature review, 63 patient interviews, 22 cognitive interviews and input from 9 experts, and the international field test study that involved 403 weight loss and 331 body contouring patients. To develop the Stretch Marks scale, we reexamined appearance codes from the original interviews. The scale was field tested in an international study. Rasch measurement theory (RMT) analysis was used to refine the scale and examine measurement properties. Results: The Stretch Marks scale was completed by 630 participants, who provided 774 assessments. After dropping 3 items, the data fit the Rasch model (P = 0.56). Items (eg, length, width, amount, location, up close) mapped out a well-targeted clinical hierarchy. All items had ordered thresholds and good item fit. There was no evidence of differential item functioning (bias) by gender, age group or language (English vs Danish). The scale evidenced high reliability (ie, person separation index = 0.94, Cronbach's alpha = 0.97). For construct validity, the mean score correlated with the total number of body areas with stretch marks, higher BMI before bariatric surgery, and other BODY-Q scales. Conclusions: This scale could be used to measure the impact of innovative treatments for stretch marks.

AB - Detecting selection on codon usage (CU) is a difficult task, since CU can be shaped by both the mutational process and selective constraints operating at the DNA, RNA, and protein levels. Yang and Nielsen (2008) developed a test (which we call CUYN) for detecting selection on CU using two competing mutation-selection models of codon substitution. The null model assumes that CU is determined by the mutation bias alone, whereas the alternative model assumes that both mutation bias and/or selection act on CU. In applications on mammalian-scale alignments, the CUYN test detects selection on CU for numerous genes. This is surprising, given the small effective population size of mammals, and prompted us to use simulations to evaluate the robustness of the test to model violations. Simulations using a modest level of CpG hypermutability completely mislead the test, with 100% false positives. Surprisingly, a high level of false positives (56.1%) resulted simply from using the HKY mutation-level parameterization within the CUYN test on simulations conducted with a GTR mutation-level parameterization. Finally, by using a crude optimization procedure on a parameter controlling the CpG hypermutability rate, we find that this mutational property could explain a very large part of the observed mammalian CU. Altogether, our work emphasizes the need to evaluate the potential impact of model violations on statistical tests in the field of molecular phylogenetic analysis. The source code of the simulator and the mammalian genes used are available as a GitHub repository (https://github.com/Simonll/LikelihoodFreePhylogenetics.git). PMID- 29596641 TI - Primed CRISPR adaptation in Escherichia coli cells does not depend on conformational changes in the Cascade effector complex detected in Vitro. AB - In type I CRISPR-Cas systems, primed adaptation of new spacers into CRISPR arrays occurs when the effector Cascade-crRNA complex recognizes imperfectly matched targets that are not subject to efficient CRISPR interference. Thus, primed adaptation allows cells to acquire additional protection against mobile genetic elements that managed to escape interference. Biochemical and biophysical studies suggested that Cascade-crRNA complexes formed on fully matching targets (subject to efficient interference) and on partially mismatched targets that promote primed adaption are structurally different. Here, we probed Escherichia coli Cascade-crRNA complexes bound to matched and mismatched DNA targets using a magnetic tweezers assay. Significant differences in complex stabilities were observed consistent with the presence of at least two distinct conformations. Surprisingly, in vivo analysis demonstrated that all mismatched targets stimulated robust primed adaptation irrespective of conformational states observed in vitro. Our results suggest that primed adaptation is a direct consequence of a reduced interference efficiency and/or rate and is not a consequence of distinct effector complex conformations on target DNA.

AB - The resurfacing of soft tissue over extensor side of elbow joint after a full thickness burn injury is challenging due to greater amount of soft tissue needed. Local or regional flaps in the upper limb are not readily available and the use of free flap is the consensus. We want to present the first report of an extra large anterolateral thigh (ALT) flap for a 1-stage coverage of an extensive elbow defect. The versatility of the ALT flap in design offers the surgeon the added option of supercharging the flap for increased survival when using a large flap for extensive wound coverage in the elbow. A 36-year-old male was admitted due to full thickness contact thermal burn over extensor side of left elbow. After debridement, we applied a 1-stage reconstruction with an extra-large ALT flap for the wound coverage and a supercharging design was made for the better perfusion for the flap. The flap was well perfused and the patient was discharged under stable wound condition as well as a fair functional outcome. The ALT flap is ideal for resurfacing large defects over the elbow and its anatomy and multiple source perforators allow the use of supercharging to enhance flap survival in the upper limb. PMID- 29596642 TI - The DNA damage response activates HPV16 late gene expression at the level of RNA processing. AB - We show that the alkylating cancer drug melphalan activated the DNA damage response and induced human papillomavirus type 16 (HPV16) late gene expression in an ATM- and Chk1/2-dependent manner. Activation of HPV16 late gene expression included inhibition of the HPV16 early polyadenylation signal that resulted in read-through into the late region of HPV16. This was followed by activation of the exclusively late, HPV16 splice sites SD3632 and SA5639 and production of spliced late L1 mRNAs. Altered HPV16 mRNA processing was paralleled by increased association of phosphorylated BRCA1, BARD1, BCLAF1 and TRAP150 with HPV16 DNA, and increased association of RNA processing factors U2AF65 and hnRNP C with HPV16 mRNAs. These RNA processing factors inhibited HPV16 early polyadenylation and enhanced HPV16 late mRNA splicing, thereby activating HPV16 late gene expression.

AB - Water, sanitation, and handwashing interventions may confer spillover effects on neighbors of intervention recipients by interrupting pathogen transmission. We measured geographically local spillovers in WASH Benefits, a cluster-randomized trial in rural Bangladesh, by comparing outcomes among neighbors of intervention vs. control participants. WASH Benefits randomly allocated geographically-defined clusters to a compound-level intervention (chlorinated drinking water, upgraded sanitation, and handwashing promotion) or control. From January to August 2015, in 180 clusters, we enrolled 1,799 neighboring children age-matched to trial participants that would have been eligible for WASH Benefits had they been conceived slightly earlier or later. After 28 months of intervention, we quantified fecal indicator bacteria in toy rinse and drinking water samples, measured soil-transmitted helminth infections, and recorded caregiver-reported diarrhea and respiratory illness. Neighbors' characteristics were balanced across arms. The prevalence of detectable E. coli in tubewell samples was lower for neighbors of intervention vs. control trial participants (prevalence ratio = 0.83; 0.73, 0.95). There was no difference in fecal indicator bacteria prevalence between arms for other environmental samples. Prevalence was similar in neighbors of intervention vs. control participants for soil-transmitted helminth infection, diarrhea, and respiratory illness. A compound-level water, sanitation, and handwashing intervention reduced neighbors' tubewell water contamination but did not impact neighboring children's health. PMID- 29596645 TI - Combined Use of Predatory Mirids With Amblyseius swirskii (Acari: Phytoseiidae) to Enhance Pest Management in Sweet Pepper. AB - The combined release of Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) with Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) provides effective control of sweet pepper key pests, such as thrips and whiteflies. However, the management of the aphids can still be improved. Recently, the predatory mirids Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) and Macrolophus pygmaeus (Rambur) (Hemiptera: Miridae) have been found to be effective in the control of aphids, thrips and whiteflies when tested alone. Hence, integrating one of these two mirids with A. swirskii might enhance sweet pepper pest management. In this work, we began by investigating the co-occurrence of both mirid species when released together with A. swirskii. This was compared to the standard release of O. laevigatus with A. swirskii. N. tenuis and A. swirskii were involved in a bidirectional intraguild predation (IGP). On the contrary, this interaction (IGP) was apparently unidirectional in the case of M. pygmaeus with A. swirskii and O. laevigatus with A. swirskii. Both, M. pygmaeus and O. laevigatus significantly reduced the abundance of A. swirskii. Secondly, in a greenhouse experiment, where the same release combinations were tested (either N. tenuis, M. pygmaeus or O. laevigatus combined with A. swirskii), IGP seemed to be neutralized. Mirids with A. swirskii significantly suppressed thrips, whitefly, and aphid infestations. Contrarily, the combined use of O. laevigatus with A. swirskii did not reached a satisfactory control for aphids, despite the reduction in thrips and whitefly densities. Therefore, our results suggest that the use of mirids combined with A. swirskii could result in more efficient and robust biological control programs in sweet pepper crops. PMID- 29596646 TI - New single capsule of bismuth, metronidazole and tetracycline given with omeprazole versus quadruple therapy consisting of bismuth, omeprazole, amoxicillin and clarithromycin for eradication of Helicobacter pylori in duodenal ulcer patients: a Chinese prospective, randomized, multicentre trial. AB - Objectives: To assess the efficacy and safety of omeprazole given with the new single capsule of bismuth, metronidazole and tetracycline (OBMT) compared with quadruple treatment consisting of omeprazole, bismuth, amoxicillin and clarithromycin (OBAC) for Helicobacter pylori eradication in duodenal ulcer patients. Methods: This single-blind, randomized multicentre trial was conducted in 10 tertiary hospitals in China between January 2013 and April 2014. Patients were randomized to receive 10 days of OBMT therapy or 10 days of OBAC therapy. Our primary outcome was the H. pylori eradication rate, confirmed by negative [13C]urea breath tests 20-25 days after the end of omeprazole maintenance. Antibiotic resistance was determined by Etest. This study is registered with ClinicalTrials.gov, number ChiCTR-TRC-13003143. Results: One hundred and ninety two patients received OBMT therapy and 192 received OBAC therapy. There was no significant difference between the eradication rates achieved by OBMT and OBAC in either the ITT analysis (86.46% versus 87.50%, P = 0.762) or the PP analysis (94.58% versus 93.06%, P = 0.563). The efficacies of OBMT and OBAC were not affected by metronidazole or clarithromycin resistance. Treatment-emergent adverse events (TEAEs) for both treatments were similar; gastrointestinal and CNS symptoms were the most commonly reported. Conclusions: The new single-capsule OBMT quadruple therapy is as effective and well tolerated as the widely used OBAC therapy for treatment of H. pylori in clinical practice in China. In addition, this OBMT therapy largely overcomes H. pylori metronidazole and clarithromycin resistance. PMID- 29596647 TI - ASAS-SSR Triennial Reproduction Symposium: Looking Back And Moving Forward-How Reproductive Physiology Has Evolved: Male reproductive behavior: sensory signaling in the brain of low-performing domestic rams. AB - Rams are selected for genetic traits a producer desires to propagate in his flock. Even though practically all sheep are naturally bred, rams are rarely evaluated for expression of sexual interest or behavior. Research at the U.S. Sheep Experiment Station reported that the proportion of rams with limited interest in ewes was nearly 30% of the total number of breeding rams. Breeding soundness tested rams with low sexual interest sire less than 16% of the lamb crop. Although producers recognize the problem, their usual solution is to increase the number of rams in breeding flocks decreasing the risk of open ewes. Increased costs and a lack of genetic progress are clearly important considerations, but the biological question as to what controls sexual interest remains intriguing. Circulating concentrations of testosterone do not differ by sexual interest among rams. However, following exposure to estrous ewes, sexually active, but not inactive, rams exhibit an increase in LH pulsatile activity, a biological response to sexual stimuli. This begs the question as to whether sexually inactive rams recognize sexual cues. Using c fos activity as an indicator of neural activity, differences in the olfactory pathway were compared among sexually active and inactive rams. Differences in fos activity were not detected in the olfactory bulb or medial amygdala. However, sexually inactive rams had lower fos activity in the central amygdala, bed nucleus of the stria terminalis, and medial preoptic area of the hypothalamus following exposure to sexual evocative olfactory stimuli. This suggests sexually inactive rams detect olfactory cues but have decreased vigilance to sensory stimuli and a muted response to sexual signals in areas of the brain required for the execution of sexual performance. With the amygdala receiving and integrating sensory signals from many areas of the brain, sexually inactive rams may lack normal reward mechanisms contributing to their lack of sexual interest. Rams with limited sexual interest have decreased dopamine synthesis and a lower expression of dopamine D2 receptors following exposure to sexual stimuli. Thus, a tempered reward pathway in combination with decreased vigilance and sensory processing in the amygdala may reduce stimulation and/or responsiveness in areas of the brain required for expression of sexual behavior. PMID- 29596648 TI - Quantification of an Exercise Rehabilitation Program for Severely Burned Children: The Standard of Care at Shriners Hospitals for Children(r)-Galveston. AB - Currently, there are no clear guidelines for the implementation of rehabilitative exercise training (RET) in burned individuals. Therefore, we quantified the training logs for exercise intensity, frequency, and duration of 6 weeks of this program to develop a basic framework for outpatient RET in patients recovering from severe burns. Thirty-three children (11 female, [mean +/- SD] 12 +/- 3 years, 145 +/- 18 cm, 40 +/- 11 kg, 49 +/- 31 BMI percentile) with severe burns (49 +/- 15% total body surface area burned, with 35 +/- 22% third-degree burns) completed our 6-week resistance and aerobic exercise training program. Cardiorespiratory fitness (peak VO2), strength, power, and lean body mass (LBM) were measured before and after RET. Outcome measures were analyzed as a relative percentage of values in age- and sex-matched nonburned children (11 female, 12 +/ 3 years, 154 +/- 20 cm, 49 +/- 22 kg, 56 +/- 25 BMI percentile). At discharge, burned children had lower LBM (77% of age-sex-matched nonburn values), peak torque (53%), power (62%), and cardiorespiratory fitness (56%). After 6 weeks of training, LBM increased by 5% (82% of nonburn values), peak torque by 18% (71%), power by 20% (81%), and cardiorespiratory fitness by 18% (74%; P < .0001 for all). Quantification of data in exercise training logs suggested that physical capacity can be improved by aerobic exercise training performed at five metabolic equivalents (>70% of peak VO2) at least 3 days/week and 150 minutes/week and by resistance training performed at volume loads (reps * sets * weight) of 131 kg for the upper body and 275 kg for the lower body for 2 days/week. We present for the first time the quantification of our RET and provide clear exercise prescription guidelines specific to children with severe burn injury. PMID- 29596650 TI - Micronutrients, iodine status and concentrations of thyroid hormones: a systematic review. AB - Context: The metabolism of thyroid hormones, which are essential for normal development, involves many proteins and enzymes. It requires iodine as a key component but is also influenced by several other micronutrients, including selenium, zinc, iron, and vitamin A. Objective: This systematic review was designed to investigate the effect of micronutrient status and supplementation on iodine status and thyroid hormone concentrations. Data Sources: Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, electronic databases were searched from their inception to April 2016. Study Selection: Human studies published in English and reporting data on micronutrient status and iodine status and/or thyroid hormone concentrations were included. Studies that examined the effect of micronutrient supplementation on iodine status and/or thyroid hormone concentrations were also included. Data Extraction: A predesigned and piloted data extraction form was used to compile data from individual studies. Results: A total of 57 studies were included: 20 intervention studies and 37 observational studies. Although observational evidence suggests that concentrations of selenium, zinc, and iron are positively associated with iodine status, data from randomized controlled trials fail to confirm this relationship. Conclusions: Further studies are needed to provide greater understanding of the role of micronutrient status in iodine nutrition and thyroid function to ascertain the public health implications for populations worldwide. PMID- 29596652 TI - Corrigendum. PMID- 29596649 TI - The loss of SMG1 causes defects in quality control pathways in Physcomitrella patens. AB - Nonsense-mediated mRNA decay (NMD) is important for RNA quality control and gene regulation in eukaryotes. NMD targets aberrant transcripts for decay and also directly influences the abundance of non-aberrant transcripts. In animals, the SMG1 kinase plays an essential role in NMD by phosphorylating the core NMD factor UPF1. Despite SMG1 being ubiquitous throughout the plant kingdom, little is known about its function, probably because SMG1 is atypically absent from the genome of the model plant, Arabidopsis thaliana. By combining our previously established SMG1 knockout in moss with transcriptome-wide analysis, we reveal the range of processes involving SMG1 in plants. Machine learning assisted analysis suggests that 32% of multi-isoform genes produce NMD-targeted transcripts and that splice junctions downstream of a stop codon act as the major determinant of NMD targeting. Furthermore, we suggest that SMG1 is involved in other quality control pathways, affecting DNA repair and the unfolded protein response, in addition to its role in mRNA quality control. Consistent with this, smg1 plants have increased susceptibility to DNA damage, but increased tolerance to unfolded protein inducing agents. The potential involvement of SMG1 in RNA, DNA and protein quality control has major implications for the study of these processes in plants.

PMID- 29596651 TI - The Influence of Obesity on the Pharmacokinetics of Dioxin in Mice: An Assessment Using Classical and PBPK Modeling. AB - The effects of body fat mass on the elimination of 2,3,7,8-tetrachlorodibenzo-p dioxin (TCDD) was examined in mice. When male C57BL/6J mice are fed a high-fat, simple carbohydrate diet (HFD) for 13 weeks, they develop an obese phenotype. In contrast, A/J mice fed an HFD do not become obese. After 13 weeks on a normal diet (ND) or HFD, male C57BL/6J and A/J mice received a single dose by gavage of 0.1 or 5.0 ug of 2,3,7,8-tetrachloro[1,6-3H] dibenzo-p-dioxin per kg body weight. Using classical pharmacokinetics, the blood elimination half-life of TCDD was approximately 10 and 2 times longer in the C57BL/6J on the HFD compared with the mice on the ND at 0.1 and 5.0 MUg/kg doses, respectively. The diet did not increase the blood half-life of TCDD in the A/J mice, which did not get obese. Using a physiologically based pharmacokinetic model for TCDD that incorporated experimentally derived percent body fat mass and tissue partition coefficients, as well as data on hepatic sequestration, did not provide accurate predictions to the data and could not explain the increase in half-life of TCDD in the HFD groups. This work demonstrates that obesity influences the half-life of TCDD, but other undetermined factors are involved in its elimination because the increase in body fat mass, decreases in cytochrome P4501A2, and altered partition coefficients could not completely explain the prolonged half-life. PMID- 29596654 TI - Effects of Irradiation Dose on Sperm Production, Insemination, and Male Mating Possible Period in the Sweetpotato Weevil (Coleoptera: Brentidae). AB - The sterile insect technique (SIT) has been used for the control or eradication of target insect pests. To successfully apply SIT, it is very important to clarify the effect of irradiation on male reproduction in the target pest, because their mating and spermiogenesis abilities affect the success of eradication program. The sweetpotato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae) is a notorious and worldwide pest of sweet potato. We investigated the effect of irradiation at five doses ranging from 0 (control) to 150 Gy on 9-d-old males. Survival rate of the control (no treatment) remained high from day 10 to 20 of adult life, whereas higher doses of irradiation reduced it, maximally by approximately 70%. Mating rates showed a similar tendency. Radiation dose neither affected sperm production nor sperm transfer at any dose, although spermiogenesis is active during the adult stage. However, radiation dose affected the lifetime total of ejaculated sperm number, likely because of fewer matings by irradiated males. These results suggest that use of a dose of 150 Gy or higher is appropriate for the final step of eradication of this weevil. At least, lower dose of irradiation may arise the inadequate sterilization, resulting in a failure of eradication program. We conclude that weekly release of sweetpotato weevil sterilized with high dose, achieving complete sterilization, could be useful for eradication program after reducing the population by male annihilation method.

PMID- 29596655 TI - Enhanced Hepatic PPARalpha Activity Links GLUT8 Deficiency to Augmented Peripheral Fasting Responses in Male Mice. AB - The adaptive fasting response is invoked as a promising cardiometabolic and neurodegenerative therapeutic pathway. We and others have defined the carbohydrate transporter glucose transporter 8 (GLUT8) as a critical regulator of hepatic and whole-organism metabolic homeostasis in the overfed and diabetic states. However, the functions of this critical transporter in the physiological fasting response remain poorly understood. Here, we tested the hypothesis that GLUT8 modulates the adaptive hepatic fasting response. We demonstrate that mice with targeted Slc2a8 disruption exhibit enhanced thermogenesis, ketogenesis, and peripheral lipid mobilization during fasting. These metabolic enhancements were observed in the context of mildly impaired hepatic mitochondrial oxidative metabolism in vivo and in vitro. Mechanistically, we show that hepatic peroxisome proliferator-activated receptor alpha (PPARalpha) and its transcriptional fasting response target hepatokine, fibroblast growth factor (FGF)21, are cell autonomously hyperactivated in GLUT8-deficient liver and in isolated primary murine hepatocytes during nutrient depletion. Hepatic PPARalpha knockdown in GLUT8-deficient mice normalized the enhanced ketogenic and FGF21 secretory responses and decreased mitochondrial respiratory function without altering the hyperthermic response to fasting. Our data demonstrate that hepatocyte GLUT8 regulates adaptive fasting in part through regulation of the PPARalpha signaling cascade. Moreover, the ketotic and thermic responses to fasting are differentially encoded within the GLUT8-PPARalpha communication axis. GLUT8 therefore represents a therapeutic target that can be leveraged against cardiometabolic disease. PMID- 29596658 TI - Effect of resveratrol supplementation on cognitive performance and mood in adults: a systematic literature review and meta-analysis of randomized controlled trials. AB - Context: The aim of this systematic review was to evaluate clinical trial data regarding the effect of resveratrol supplementation on cognitive performance and mood in populations that are healthy and in the clinical setting. Data Sources: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature review of randomized controlled trials was conducted. Data Extraction: A meta-analysis was also conducted to determine treatment effect on the following cognitive domains and mental processes: processing speed, number facility, memory, and mood. Risk of bias was assessed using the Cochrane Collaboration Risk of Bias tool. Quality of the body of evidence was assessed by evidence for each outcome related to cognitive function for which data was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Results: Ten studies were included. Three studies found resveratrol supplementation significantly improved some measures of cognitive performance, 2 reported mixed findings, and 5 found no effect. When data were pooled, resveratrol supplementation had a significant effect on delayed recognition (standardized mean difference [SMD], 0.39; 95% confidence interval [CI], 0.08-0.70; I2 = 0%; P = 0.01; n = 3 studies; n = 166 participants) and negative mood (SMD, -0.18; 95%CI, -0.31 to -0.05; I2 = 0%; P = 0.006; n = 3 studies; n = 163 participants). Included studies generally had low risk of bias and were of moderate or high quality. Conclusions: The results of this review indicate that resveratrol supplementation might improve select measures of cognitive performance; however, the current literature is inconsistent and limited. PMID- 29596657 TI - Attenuating effect of melatonin on lipopolysaccharide-induced chicken small intestine inflammation. AB - Enriched melatonin (MEL) has been found in the mammalian intestine and has been recently demonstrated to alleviate rodent colitis. In this study, the effect of MEL on lipopolysaccharide (LPS)-induced intestinal inflammations was investigated in new chicken hatchlings. The chicks were fed with a diet supplemented with MEL (12.5 mg/day) from D1 to D10. Meanwhile, the chicks in the LPS or MEL + LPS groups were injected with LPS (10 mg/kg BW, i.p.) at D10. LPS treatment for 6 h increased the expression of IL-6, IL-4, caspase-3 mRNAs and TUNEL-positive cell populations, but decreased populations of the goblet and PCNA+ cells, IgA production and the expression of MUC2 mRNA in the duodenum. Compared with the LPS group, MEL pre-feeding alleviated duodenal inflammation and decreased the expression of TNF-alpha mRNAs by 23.6% (P = 0.004), IL-6 mRNAs by 69.4% (P = 0.001), IL-4 mRNAs by 4.1% (P = 0.824) and caspase-3 mRNAs by 45.8% (P < 0.001). Conversely, MEL pre-feeding attenuated the LPS-induced changes of IgA production by 161.6% (P = 0.013) and PCNA+ cell populations by 172.1% (P < 0.001) in the duodenum. TLR4 mRNA was also up-regulated by LPS treatment but down-regulated by MEL pre-feeding. In conclusion, dietary MEL could attenuate LPS-induced chick duodenal inflammation by down-regulating the expression of inflammatory cytokines, promoting epithelial cell proliferation, improving the immunological barrier and inhibiting epithelial apoptosis via the mediation of TLR4. PMID- 29596659 TI - The degree of radiation-induced DNA strand breaks is altered by acute sleep deprivation and psychological stress and is associated with cognitive performance in humans. AB - Study Objectives: Sleep deprivation is associated with impaired immune responses, cancer, and morbidity and mortality, and can degrade cognitive performance, although individual differences exist in such responses. Sleep deprivation induces DNA strand breaks and DNA base oxidation in animals, and psychological stress is associated with increased DNA damage in humans. It remains unknown whether sleep deprivation or psychological stress in humans affects DNA damage response from environmental stressors, and whether these responses predict cognitive performance during sleep deprivation. Methods: Sixteen healthy adults (ages 29-52 years; mean age +/- SD, 36.4 +/- 7.1 years; seven women) participated in a 5-day experiment involving two 8 hr time-in-bed (TIB) baseline nights, followed by 39 hr total sleep deprivation (TSD), and two 8-10 hr TIB recovery nights. A modified Trier Social Stress Test was conducted on the day after TSD. The Psychomotor Vigilance Test measured behavioral attention. DNA damage was assessed in blood cells collected at 5 time points, and blood cells were irradiated ex vivo. Results: TSD, alone or in combination with psychological stress, did not induce significant increases in DNA damage. By contrast, radiation-induced DNA damage decreased significantly in response to TSD, but increased back to baseline when combined with psychological stress. Cognitively vulnerable individuals had more radiation-induced DNA strand breaks before TSD, indicating their greater sensitivity to DNA damage from environmental stressors. Conclusions: Our results provide novel insights into the molecular consequences of sleep deprivation, psychological stress, and performance vulnerability. They are important for fields involving sleep loss, radiation exposure, and cognitive deficits, including cancer therapy, environmental toxicology, and space medicine. PMID- 29596660 TI - Metabolic Activation of the Cooked Meat Carcinogen 2-Amino-1-Methyl-6 Phenylimidazo[4,5-b]Pyridine in Human Prostate. AB - 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), an heterocyclic aromatic amine (HAA) formed in cooked meat, is a rodent and possible human prostate carcinogen. Recently, we identified DNA adducts of PhIP in the genome of prostate cancer patients, but adducts of 2-amino-3, 8-dimethylmidazo[4,5-f]quinoxaline (MeIQx) and 2-amino-9 H-pyrido[2,3-b]indole (AalphaC), other prominent HAAs formed in cooked meats, were not detected. We have investigated the bioactivation of HAAs by Phase I and II enzymes in the human prostate (LNCaP) cell line using cytotoxicity and DNA adducts as endpoints. PhIP, MeIQx, and 2-amino-3 methylimidazo[4,5-f]quinoline, another HAA found in cooked meats, were poorly bioactivated and not toxic. The synthetic genotoxic N-hydroxylated-HAAs were also assayed in LNCaP cells with Phase II enzyme inhibitors. Notably, 2-hydroxy-amino 1-methyl-6-phenylimidazo[4,5-b]pyridine (HONH-PhIP), but not other HONH-HAAs, induced cytotoxicity. Moreover, PhIP-DNA adduct formation was 20-fold greater than adducts formed with other HONH-HAAs. Pretreatment of LNCaP cells with mefenamic acid, a specific inhibitor of sulfotransferase (SULT1A1), decreased PhIP-DNA adducts by 25%, whereas (Z)-5-(2'-hydroxybenzylidene)-2 thioxothiazolidin-4-one and pentachlorophenol, inhibitors of SULTs and N acetyltransferases (NATs), decreased the PhIP-DNA adduct levels by 75%. NATs in cytosolic fractions of LNCaP cells and human prostate catalyzed DNA binding of HONH-PhIP by up to 100-fold greater levels than for SULT and kinase activities. Recombinant NAT2 is catalytically superior to recombinant NAT1 in the bioactivation of HONH-PhIP; however, the extremely low levels of NAT2 activity in prostate suggest that NAT1 may be the major isoform involved in PhIP-DNA damage. Thus, the high susceptibility of LNCaP cells recapitulates the DNA-damaging effect of HONH-PhIP in rodent and human prostate.

Ever use and past 30-day use prevalence estimates of specific products were impacted by respondents answering breakout items or breakout items with images compared to respondents answering a checklist of items in the survey. Current surveys that include a "select all that apply" list format may be underestimating ever and past 30-day prevalence estimates of tobacco products. PMID- 29596663 TI - Assessing Psychological Fitness in the Military - Development of an Effective and Economic Screening Instrument. AB - Background: There are a high number of soldiers with deployment-related and non deployment-related mental health problems in the German Armed Forces (Bundeswehr): This has led to an increase in mental disorders and a decrease in quality of life. To tackle these problems and to strengthen resources among the Bundeswehr personnel, this study aims at developing a screening instrument for assessing the psychological fitness of soldiers on the basis of questionnaire scales. In this approach, psychological fitness describes a soldier's ability to integrate and enhance his/her mental and emotional capabilities using resources and trainable skills. Methods: Bundeswehr combat soldiers (N = 361) answered questionnaires about resilience (RS-11), sense of coherence (SOC-L9), quality of life (WHOQOL-BREF), mental disorders (PHQ-D) and post-traumatic growth (PTG). Additionally, they were interviewed by trained troop psychologists both before and after their deployment in Afghanistan from January to June 2014. The screening model is based on self-report data; the psychological fitness in the standardized interview serves as a validation standard. Findings: A linear logistic regression model was performed that includes the social relationship and the psychological scale from WHOQOL-BREF and the somatoform and the stress scale from PHQ. This model allows specialists a first assessment between participants who are psychologically fit before and after deployment and those who are less so. The chosen cutoff for sensitivity is between 70% and 79% and for specificity between 70% and 85%. Discussion: This screening approach is still not applicable to large populations like that of the Bundeswehr, which currently has about 170,000 soldiers but it is limited to deployed combat troops. Classifying psychological fitness allows specialists to differentiate between people in need of special training or additional diagnostic measures and those in need of sustaining their fitness regularly at the earliest possible stage. A follow-up study that is representative of deployed and non-deployed military personnel will examine whether these results can be transferred to the entire Bundeswehr and whether the validity of the interview can be established.

Current treatment options (both pharmaco- and psychotherapy) have shown efficacy, but for many leave a shortfall in recovery. Advances in the understanding of the pathophysiology of bipolar disorder suggest that interventions that target mitochondrial dysfunction may provide a therapeutic benefit. Methods: This review explores the current and growing theoretical rationale as well as existing preclinical and clinical data for those therapies aiming to target the mitochondrion in bipolar disorder. A Clinicaltrials.gov and ANZCTR search was conducted for complete and ongoing trials on mitochondrial agents used in psychiatric disorders. A PubMed search was also conducted for literature published between January 1981 and July 2017. Systematic reviews, randomized controlled trials, observational studies, case series, and animal studies with an emphasis on agents affecting mitochondrial function and its role in bipolar disorder were included. The search was augmented by manually searching the references of key papers and related literature. The results were presented as a narrative review. Results: Mitochondrial agents offer new horizons in mood disorder treatment. While some negative effects have been reported, most compounds are overall well tolerated and have generally benign side-effect profiles. Conclusions: The study of neuroinflammation, neurodegeneration, and mitochondrial function has contributed the understanding of bipolar disorder's pathophysiology. Agents targeting these pathways could be a potential therapeutic strategy. Future directions include identification of novel candidate mitochondrial modulators as well as rigorous and well-powered clinical trials.

AB - To establish the effectiveness of a nurse-led postoperative MOBILITY program implemented on the Burn/Surgical/Trauma unit at our facility to increase documentation of patient mobility and to develop nurse and patient understanding of the importance of movement in postoperative recovery while increasing patient satisfaction with mobility. The MOBILITY program was implemented on a 24-bed Burn/Surgical/Trauma unit. Lewin's Change Theory guided the development of the program, while the Iowa Model of Evidence-Based Practice for Quality Care was the framework for the project. Nursing staff (n = 20) on the Burn/Trauma unit completed pre/postimplementation MOBILITY surveys. Pre/postimplementation MOBILITY patient (n = 9) satisfaction questionnaires were completed by postoperative patients. Retrospective chart (n = 10) audits were performed pre/postimplementation. Included in the chart audits and patient satisfaction surveys were patients 72 hours or less postoperatively without lower limb weight bearing restrictions. Those excluded were patients on complete bed rest, or those with bilateral or unilateral nonweight-bearing orders. Documentation of mobility improved by 233.3%, while ambulation distance documentation increased by 700%. Mobility orders entered by the medical team rose by 66.7% postintervention. Nurses' comfort level with assessing mobility improved by 38.5%. Knowledge of where to document patient postoperative mobility improved by 80%. Postintervention patient satisfaction with postoperative mobility saw a 60% change. Patients performing postoperative mobility increased by 80%. Implementation of a nurse-led postoperative MOBILITY program on a Burn/Surgical/Trauma unit showed a marked increase in nurse and patient understanding of postoperative mobility, patient satisfaction with postoperative mobility, and nursing documentation of patient mobility. PMID- 29596679 TI - Burn Injuries in Patients with Paralysis: A National Perspective on Injury Patterns and Outcomes. AB - The affect of paralysis-related comorbidities on outcomes in burn-injured patients has not been explored. We hypothesize that comorbid paralysis is associated with increased morbidity in this population. All burned patients with prior diagnoses of paralysis were identified from the National Burn Repository (Version 8.0). One-to-one matching of nonparalyzed burn-injured patients was performed, and nonparametric analysis was used to compare the groups. We identified 432 paralyzed patients, who were predominantly male (70.6%) and Caucasian (57.6%), with an average age of 40.8 +/- 19.0 years. The identified level of disability was distinguished as paraplegia (59.5%), hemiplegia (16.9%), quadriplegia (13.9%), or other (9.8%). A majority of injuries occurred in the home (75.2%), primarily due to scalds (48.1%). More than half sustained small injuries with affected total body surface area <5%. Lower extremities were frequently injured (72.2%), with 41.0% affecting exclusively the lower extremities. While the paralysis population had significantly longer hospital lengths of stay, nonparalyzed patients had longer intensive care unit length of stay and ventilator days (P < .001). There was no statistically significant difference in mortality rate between paralyzed and nonparalyzed patients (4.4% vs 4.9%, P = .550). Patients with paralysis are susceptible to small scald injuries in the home. Comorbid paralysis places patients at risk for longer, more indolent hospital stays, when compared with matched nonparalyzed patients with more critical illness. Further investigation is needed regarding the pathophysiologic mechanisms predisposing paralyzed burn patients to increased morbidity. PMID- 29596680 TI - Differential antiviral activities of respiratory syncytial virus (RSV) inhibitors in human airway epithelium. AB - Objectives: We report the use of reconstituted 3D human airway epithelium cells (HuAECs) of bronchial origin in an air-liquid interface to study respiratory syncytial virus (RSV) infection and to assess the efficacy of RSV inhibitors in (pre-)clinical development. Methods: HuAECs were infected with RSV-A Long strain (0.01 CCID50/cell, where CCID50 represents 50% cell culture infectious dose in HEp2 cells) on the apical compartment of the culture. At the time of infection or at 1 or 3 days post-infection, selected inhibitors were added and refreshed daily on the basal compartment of the culture. Viral shedding was followed up by apical washes collected daily and quantifying viral RNA by RT-qPCR. Results: RSV-A replicates efficiently in HuAECs and viral RNA is shed for weeks after infection. RSV infection reduces the ciliary beat frequency of the ciliated cells as of 4 days post-infection, with complete ciliary dyskinesia observed by day 10. Treatment with RSV fusion inhibitors resulted in an antiviral effect only when added at the time of infection. In contrast, the use of replication inhibitors (both nucleoside and non-nucleoside) elicited a marked antiviral effect even when the start of treatment was delayed until 1 day or even 3 days after infection. Levels of the inflammation marker RANTES (mRNA) increased ~200-fold in infected, untreated cultures (at 3 weeks post-infection), but levels were comparable to those of uninfected cultures in the presence of PC786, an RSV replication inhibitor, suggesting that an efficient antiviral treatment might inhibit virus induced inflammation in this model. Conclusions: Overall, HuAECs offer a robust and physiologically relevant model to study RSV replication and to assess the efficacy of antiviral compounds. PMID- 29596681 TI - Glycoengineering design options for IgG1 in CHO cells using precise gene editing. AB - Precise gene editing technologies are providing new opportunities to stably engineer host cells for recombinant production of therapeutic glycoproteins with different glycan structures. The glycosylation of recombinant therapeutics has long been a focus for both quality and consistency of products and for optimizing and improving pharmacokinetic properties as well as bioactivity. Structures of glycans on therapeutic glycoproteins are important for circulation, biodistribution and bioactivity. In particular, the latter has been demonstrated for therapeutic IgG1 antibodies where the core alpha1,6Fucose on the conserved N glycan at Asn297 have remarkable dampening effects on antibody effector functions. We previously explored precise gene engineering and design options for N-glycosylation in CHO cells, and here we focus on engineering options possible for N-glycans on human IgG1. We demonstrate stable precise gene engineering of rather homogenous biantennary N-glycans with and without galactose (G0F, G2F) as well as the alpha2,6-linked monosialylated (G2FS1) glycoform. We were unable to introduce substantial disialylated glycoforms. Instead we engineered a novel monoantennary homogeneous N-glycan design with complete alpha2,6-linked sialic acid capping. All N-glycoforms may be engineered with and without core alpha1,6Fucose. The stably engineered design options enable production of human IgG antibodies with an array of distinct glycoforms for testing and selection of optimal design for different therapeutic applications. PMID- 29596682 TI - Helping the healer: population-informed workplace wellness recommendations for physician well-being. AB - Background: The need to keep physicians healthy and in practice is critical as demand for doctors grows faster than the supply. Workplace wellness programmes can improve employee health and retain skilled workers. Aims: To broaden our understanding about ways to help doctors coping with mental health problems and to develop population-informed workplace wellness recommendations for physician populations. Methods: Researchers surveyed physicians to document potential warning signs and prevention strategies. A survey was issued to doctors who presented to a physician health programme with mental health complaints. The survey captured respondents' feedback about how to identify and prevent mental health problems. Data were analyzed using simple descriptive statistics. Results: There were 185 participants. Half of respondents believed their problems could have been recognized sooner and 60% said they exhibited signs that could aid in earlier detection. Potential warnings included fluctuations in mood (67%), increased comments about stress/burnout (49%) and behavioural changes (32%). To improve detection, prevention and care-seeking for mental health problems, doctors endorsed multiple items related to the use of interpersonal supports, personal factors and organizational dynamics throughout the survey. Conclusions: The findings confirmed earlier work demonstrating the value of social and organizational support in maintaining physician health. It further indicated that earlier identification and/or prevention of mental health problems is not only possible, but that medical organizations are uniquely situated to carry out this work. PMID- 29596683 TI - Marjolin's Ulcer Arising in a Burn Scar. AB - Marjolin's ulcer is an aggressive disease arising in chronic wounds and cutaneous scars. Corbo et al define Marjolin's ulcer an often overlooked or misdiagnosed tumor. We report a case of Marjolin's ulcer arose in a burn scar of a 51-year-old man who sustained a burn in childhood. A punch biopsy showed squamous cell carcinoma. The lesion was surgically removed with wide excision. The loss of substance was covered with a partial-thickness skin graft, harvested from the left thigh with dermatome. Histological examination confirmed a well differentiated squamous cell carcinoma. Burn scars are the most commonly associated with these tumors, but other lesions may initiate this malignant transformation. The most common type of tumor reported in a Marjolin's ulcer is squamous cell carcinoma, but Pavlovic et al reported other malignancies. PMID- 29596684 TI - Phenomenological Load on Model Parameters Can Lead to False Biological Conclusions. AB - When a substitution model is fitted to an alignment using maximum likelihood, its parameters are adjusted to account for as much site-pattern variation as possible. A parameter might therefore absorb a substantial quantity of the total variance in an alignment (or more formally, bring about a substantial reduction in the deviance of the fitted model) even if the process it represents played no role in the generation of the data. When this occurs, we say that the parameter estimate carries phenomenological load (PL). Large PL in a parameter estimate is a concern because it not only invalidates its mechanistic interpretation (if it has one) but also increases the likelihood that it will be found to be statistically significant. The problem of PL was not identified in the past because most off-the-shelf substitution models make simplifying assumptions that preclude the generation of realistic levels of variation. In this study, we use the more realistic mutation-selection framework as the basis of a generating model formulated to produce data that mimic an alignment of mammalian mitochondrial DNA. We show that a parameter estimate can carry PL when 1) the substitution model is underspecified and 2) the parameter represents a process that is confounded with other processes represented in the data-generating model. We then provide a method that can be used to identify signal for the process that a given parameter represents despite the existence of PL. PMID- 29596685 TI - Activity matters: a web-based resource to enable people with multiple sclerosis to become more active. AB - Increasing physical activity (PA) through exercise is associated with improvements in many of the symptoms associated with multiple sclerosis (MS) such as fatigue, strength, balance, and mobility. Despite this, people with MS remain largely inactive. Interventions that are grounded in theory and that aim to change PA behavior need to be developed. The purpose of this study was to describe the development process of a web-based resource, namely, "Activity Matters," to enable people with MS to become more active. Development of the "Activity Matters" online intervention was guided by the UK's Medical Research Council (MRC) framework for the development and evaluation of complex interventions and the behavior change wheel (BCW). Seven sources of data were used to inform the process and were mapped on to both the MRC and BCW frameworks. The intervention is theoretically based, and constructs including knowledge, memory, attention and decision processes, skills, social influences, environmental context and resources, beliefs about capabilities, beliefs about consequences, goals, and emotions were recognized as important. "Activity Matters" is the first MS PA intervention to be developed using the theoretical approach outlined by the BCW and MRC complex interventions frameworks. The next phase of this work is to test the usability, acceptability, and preliminary effectiveness of "Activity Matters" among people with MS. PMID- 29596686 TI - Hypertrophic Scar Severity at Autograft Sites Is Associated With Increased Pain and Itch After Major Thermal Burn Injury. AB - Approximately three quarters of major thermal burn injury (MThBI) survivors suffer from hypertrophic scarring (HTS) and over half experience chronic pain or itch. In survivors of MThBI, HTS and chronic pain or itch are considered one of the greatest unmet challenges of postburn injury care and psychosocial reintegration. Although scarring, itch, and pain have been clinically associated, there are no prospective, multisite studies examining tissue autograft site pain or itch and scar outcomes. The authors collected a representative cohort (n = 56) of MThBI survivors who received autografting within 14 days of injury and evaluated graft-site pain or itch severity (0-10 Numeric Rating Scale) and HTS using a validated scar photograph assessment scale 6 months following MThBI. Given that stress is known to influence wound healing, the authors also assessed the relationship between previous trauma exposure, peritraumatic stress, preburn overall health (SF-12), scarring, and chronic pain or itch severity using Spearman's correlation. Association between HTS and chronic pain or itch was significant in a linear regression model adjusted for age, sex, and ethnicity (beta = 0.2, P = .033 for pain, beta = 0.2, P = .019 for itch). Results indicate that prior trauma exposure is inversely correlated (r = -.363, P = .030) with scar severity, but not pain or itch severity 6 months after MThBI. Study results suggest that preburn chronic pain or itch is associated with pathological scarring 6 months following MThBI. Results also indicate that stress may improve scarring after MThBI. Further work to understand the mechanisms that underlie both HTS and chronic pain or itch and their relationship to chronic stress is critical to the development of novel therapies to assist burn survivors recover. PMID- 29596687 TI - Initial predictors of poor survival in myositis-associated interstitial lung disease: a multicentre cohort of 497 patients. AB - Objective: To identify initial predictors of poor survival in patients with PM/DM associated interstitial lung disease (ILD). Methods: We established a multicentre retrospective cohort of incident cases of PM/DM-associated ILD from 44 institutions across Japan (Multicentre Retrospective Cohort of Japanese Patients with Myositis-associated ILD, JAMI). Inclusion criteria were an onset age ?16 years; PM/DM or clinically amyopathic DM according to the published criteria; imaging evidence of ILD; and availability of serum samples for assays of autoantibodies such as anti-melanoma differentiation-associated gene 5 and anti aminoacyl tRNA synthetase. We collected demographic data and clinical characteristics recorded at the time of diagnosis, as well as follow-up survival data. Predictors of ILD-related mortality were identified by univariate and multivariate analyses. Results: JAMI enrolled a cohort of 497 patients with PM (15%), classic DM (32%) and clinically amyopathic DM (53%). During the observation period (median 20 months), 76 died of respiratory insufficiency directly related to ILD. Univariate analysis revealed several initial parameters associated with ILD mortality, including demographic, clinical, laboratory, imaging and autoantibody variables. We used multivariate analysis with a stepwise selection of parameters to generate an appropriate predictive model, and identified the following independent risk factors for ILD mortality: age at onset ?60 years [hazard ratio (HR) = 4.3, 95% CI: 2.4, 7.5], CRP ?1 mg/dl (HR = 2.6, 95% CI: 1.5, 4.8), peripheral capillary oxygen saturation <95% (HR = 2.0, 95% CI: 1.2, 3.4) and anti-melanoma differentiation-associated gene 5 antibody (HR = 7.5, 95% CI: 2.8, 20.2). Conclusion: We established a large cohort of incident cases of PM/DM-associated ILD, and successfully identified independent predictors of short-term ILD mortality. PMID- 29596691 TI - Prevalence and Causes of Visual Loss Among the Indigenous Peoples of the World: A Systematic Review. AB - Importance: Studies have documented a higher disease burden in indigenous compared with nonindigenous populations, but no global data on the epidemiology of visual loss in indigenous peoples are available. A systematic review of literature on visual loss in the world's indigenous populations could identify major gaps and inform interventions to reduce their burden of visual loss. Objective: To conduct a systematic review on the prevalence and causes of visual loss among the world's indigenous populations. Evidence Review: A search of databases and alternative sources identified literature on the prevalence and causes of visual loss (visual impairment and blindness) and eye diseases in indigenous populations. Studies from January 1, 1990, through August 1, 2017, that included clinical eye examinations of indigenous participants and, where possible, compared findings with those of nonindigenous populations were included. Methodologic quality of studies was evaluated to reveal gaps in the literature. Findings: Limited data were available worldwide. A total of 85 articles described 64 unique studies from 24 countries that examined 79 598 unique indigenous participants. Nineteen studies reported comparator data on 42 085 nonindigenous individuals. The prevalence of visual loss was reported in 13 countries, with visual impairment ranging from 0.6% in indigenous Australian children to 48.5% in native Tibetans 50 years or older. Uncorrected refractive error was the main cause of visual impairment (21.0%-65.1%) in 5 of 6 studies that measured presenting visual acuity. Cataract was the main cause of visual impairment in all 6 studies measuring best-corrected acuity (25.4%-72.2%). Cataract was the leading cause of blindness in 13 studies (32.0%-79.2%), followed by uncorrected refractive error in 2 studies (33.0% and 35.8%). Conclusions and Relevance: Most countries with indigenous peoples do not have data on the burden of visual loss in these populations. Although existing studies vary in methodologic quality and reliability, they suggest that most visual loss in indigenous populations is avoidable. Improvements in quality and frequency of research into the eye health of indigenous communities appear to be required, and coordinated eye care programs should be implemented to specifically target the indigenous peoples of the world. PMID- 29596688 TI - Age-Related Susceptibility to Epileptogenesis and Neuronal Loss in Male Fischer Rats Exposed to Soman and Treated With Medical Countermeasures. AB - Elderly individuals compose a large percentage of the world population; however, few studies have addressed the efficacy of current medical countermeasures (MCMs) against the effects of chemical warfare nerve agent exposure in aged populations. We evaluated the efficacy of the anticonvulsant diazepam in an old adult rat model of soman (GD) poisoning and compared the toxic effects to those observed in young adult rats when anticonvulsant treatment is delayed. After determining their respective median lethal dose (LD50) of GD, we exposed young adult and old adult rats to an equitoxic 1.2 LD50 dose of GD followed by treatment with atropine sulfate and the oxime HI-6 at 1 min after exposure, and diazepam at 30 min after seizure onset. Old adult rats that presented with status epilepticus were more susceptible to developing spontaneous recurrent seizures (SRSs). Neuropathological analysis revealed that in rats of both age groups that developed SRS, there was a significant reduction in the density of mature neurons in the piriform cortex, thalamus, and amygdala, with more pronounced neuronal loss in the thalamus of old adult rats compared with young adult rats. Furthermore, old adult rats displayed a reduced density of cells expressing glutamic acid decarboxylase 67, a marker of GABAergic interneurons, in the basolateral amygdala and piriform cortex, and a reduction of astrocyte activation in the piriform cortex. Our observations demonstrate the reduced effectiveness of current MCM in an old adult animal model of GD exposure and strongly suggest the need for countermeasures that are more tailored to the vulnerabilities of an aging population. PMID- 29596692 TI - The three peaks in age distribution of females with pneumothorax: a nationwide database study in Japan. AB - OBJECTIVES: Women are the minority among patients with spontaneous pneumothorax, but catamenial pneumothorax (CP) is unique to them. We aimed to clarify the clinical characteristics of female patients with spontaneous pneumothorax using a nationwide database. METHODS: Medical records from the Japanese Diagnosis Procedure Combination database for inpatients with pneumothorax between July 2010 and March 2016 were retrospectively reviewed. Age, underlying diseases, body mass index, smoking status, laterality, number of hospitalizations and treatments were studied. RESULTS: We identified 157 087 patients with pneumothorax, including 27 716 (17.6%) women and 129 371 (82.4%) men. The age distribution of female patients with pneumothorax had 3 peaks: 18 years, around 40 years and 80 years; male patients had 2 peaks: 18 years and 79 years. We identified 873 patients with CP; this number was not sufficient to account for the female-specific peak around 40 years. The characteristics of female patients of reproductive age were significantly different between those with and without CP. The patients with CP were older (average age: 37.9 +/- 7.7 years vs 31.3 +/- 11.5 years, P < 0.001), were right side dominant (right: 64.9%, left: 6.5%), had more hospitalizations (average number of hospitalizations: 1.6 +/- 0.9 vs 1.3 +/- 0.6, P < 0.001) and had more frequently undergone surgery (57.1% vs 37.3%, P < 0.001). CONCLUSIONS: The age distribution of women with pneumothorax had 3 distinct peaks while that of men had 2. CP has different characteristics from other types of pneumothorax, thus requiring different treatment strategies for women of reproductive age. PMID- 29596693 TI - Statistical primer: performing repeated-measures analysis. AB - Longitudinal data arise when repeated measurements are taken on the same individuals over time. Inference about between-group differences of within subject change is usually of interest. This statistical primer for cardiothoracic and vascular surgeons aims to provide a short and practical introduction of biostatistical methods on how to analyse repeated-measures data. Several methodological approaches for analysing repeated measures will be introduced, ranging from simple approaches to advanced regression modelling. Design considerations of studies involving repeated measures are discussed, and the methods are illustrated with a data set measuring coronary sinus potassium in dogs after occlusion. Cardiothoracic and vascular surgeons should be aware of the myriad approaches available to them for analysing repeated-measures data, including the relative merits and disadvantages of each. It is important to present effective graphical displays of the data and to avoid arbitrary cross sectional statistical comparisons.

AB - BACKGROUND: Patient safety is a national and global concern. In the United States, medical errors result in more than 50,000 unnecessary patient deaths annually and contribute to billions of dollars in health care costs. The purpose of this project was to evaluate a standardized bedside handoff process and its influence in a medical-surgical unit. METHOD: A quality improvement project was performed in a medical-surgical unit and consisted of development, implementation, and evaluation of a standardized bedside handoff. The project included surveying nurses, a web-based educational program, and observations using the SBAR (T) competency checklist tool. Data were analyzed for trends. RESULTS: Results identified an improved perception of communication among the nurses as it relates to shift report and a reduction in length of handoff time after the education intervention. CONCLUSION: Continual nurse education and audits by nurse leaders are vital to the sustainment of positive outcomes. J Contin Educ Nurs. 2018;49(4):157-163. PMID- 29596703 TI - Improving Rural Nurse Practitioner Knowledge About Polycystic Ovary Syndrome Through Continuing Education. AB - BACKGROUND: Polycystic ovary syndrome (PCOS), a common androgen-excess disorder in reproductive-aged women, is often a missed diagnosis. Rural nurse practitioners (NPs) need to be able to diagnose and provide basic management for PCOS. This study's objective was to determine whether a continuing education program about PCOS would improve NPs' knowledge about PCOS. METHOD: A pretest posttest design was used. Forty-eight participants attending a regional NP conference completed a pretest before a continuing education presentation about PCOS. Afterward, 43 participants completed an identical posttest. A two-step multivariate analysis of variance compared the results. RESULTS: Pretest results indicated NPs had low levels of knowledge for assessing, diagnosing, and managing PCOS. The posttest results demonstrated significant (p = .000) improvements in these areas. CONCLUSION: Continuing education presentations have the potential to increase rural NPs' knowledge about PCOS so they can provide evidence-based care to rural women with PCOS.

AB - Predatory publishers solicit manuscripts through e-mail invitations to potential authors, with the goal of enticing authors to submit a manuscript to the journal. This descriptive study examined the characteristics of 206 e-mail invitations from predatory journals and publishers sent to faculty and students in a school of nursing over a 10-week period. Characteristics of these e-mails included use of flattering language, due dates for submissions close to the date of the e-mail sent, requests for general topics, and awkward phrases. However, many e-mails did not have characteristics that clearly identified them as coming from a predatory journal or publisher. Education on predatory publishing is needed for all nurse authors, specifically how to identify and confirm whether a journal is predatory or legitimate. J Contin Educ Nurs. 2018;49(4):171-177. PMID- 29596705 TI - Evaluation of a Pain Management Education Program and Operational Guideline on Nursing Practice, Attitudes, and Pain Management. AB - Nurses lack adequate pain management knowledge, which can result in poorly managed postsurgical pain. This study aimed to develop, implement, and evaluate pain management education and operational guidelines to improve nursing knowledge and pain management. This quality improvement project employed convenience samples of surgical oncology nurses and postoperative patients. The intervention involved an online module, live education, and operational guideline for pain management. Nurses completed pre- and postintervention practice and attitudes surveys. Random chart reviews of intravenous narcotic administrations the day before discharge were completed to evaluate whether narcotic administration changed after intervention. Readmissions and Hospital Consumer Assessment of Healthcare Providers and Systems data were collected to determine whether the intervention influenced patient satisfaction. A statistically significant improvement in nursing practice and intravenous narcotic administrations demonstrated changes to pain management practices employed by the nursing staff. Although not statistically significant, fewer pain-related readmissions occurred postintervention. Findings demonstrate that targeted pain management continuing education, paired with operational guidelines, improves nursing practice and decreases intravenous narcotic administrations prior to discharge.

AB - Team teaching is used to describe a broad array of teaching configurations that offer benefits to students that cannot be duplicated by a single educator. Although articles and books have been written to describe team teaching in other fields, little has been written about team teaching in nursing. In a field with clinical application, team teaching offers more richness in perspective when there are two complimentary educators teaching the content. The opportunity to learn from a colleague, while guiding students, is an added benefit of team teaching. We are in an era of competition for employees and students, so institutions with a reputation for creating a commitment to learning have an advantage. Students who have the benefit of a strong team to guide their learning are more often positive ambassadors for their institution. The purpose of this article is to provide an overview of team teaching as experienced by two nurse educators. J Contin Educ Nurs. 2018;49(4):186-192. PMID- 29596707 TI - Pilot Study of a Two-Step Delirium Detection Protocol Administered By Certified Nursing Assistants, Physicians, and Registered Nurses. AB - The feasibility and acceptability of a two-step screening protocol for delirium identification was pilot tested. Step 1, a screening tool, comprises two items: "Please tell me the day of the week," and "Please tell me the months of the year backwards starting with December." If either/both items are incorrect, Step 2, a 3-minute diagnostic assessment, follows. Trained researchers enrolled 24 hospitalized older adults and identified 22% to be delirious after a reference standard assessment. Thereafter, physicians and RNs completed the two-step protocol, whereas certified nursing assistants (CNAs) completed the screener only, on the same patients. All three clinical assessments were successfully completed in 100% of enrolled participants and within the target 2-hour time window in 91%. The screener and two-step protocol achieved high sensitivities and specificities in RNs, CNAs, and physicians. Qualitative information on barriers to and facilitators of implementation was also collected. Nurses and other clinicians can feasibly implement this ultra-brief screener and two-step protocol, which holds promise to improve delirium identification.

AB - Pets are encountered in nursing homes and although they provide health benefits to individuals, they are also a source of health risks. The current study aimed to determine the frequency and types of animals in nursing homes, perceived benefits, and content of policies addressing health risks. Ninety-five administrators from unique nursing homes in Ohio completed an online survey addressing perceived benefits and risks of animals and policies in place. Animals were permitted in 99% of nursing homes, with dogs (95%), cats (85%), birds (71%), fish (55%), and farm animals (40%) most frequently reported. Respondents perceived animal interactions resulted in high health benefits for residents. Most facilities (70/75; 93%) reported having an animal policy, yet important gaps were frequently identified in the content of policies. Most respondents (75%) did not report health and safety concerns with animals in facilities. Best practice guidelines and policies should be developed and implemented in nursing homes to address requirements for different animal ownership models, range of animal species, and staff knowledge.

AB - Nursing homes use team nursing, with minimal RN presence, leaving the majority of direct care to licensed practical/vocational nurses (LPNs/LVNs) and unlicensed assistive personnel (UAP), including medication aides. The current article describes challenges faced by nursing home directors of nursing (DONs) leading and managing a team nursing approach, including consideration of scope of practice, delegation and supervision regulations, and related policy implications. A secondary data analysis was performed of qualitative data from a study to develop and test DON guidelines for delegation in nursing home practice. A convenience sample (N = 29) of current or previous DONs and other nursing home leaders with knowledge and expertise in the DON role participated in in-depth, guided interviews. The findings highlight a core concern to nursing licensure policy and regulation: knowledge and practice gaps related to scope of practice and delegation and supervision among DONs, RNs, and LPNs/LVNs, as well as administrators, and the role of nursing leaders in supporting appropriate delegation practices. The findings offer directions for research and practice in addressing challenges in aligning team nursing practices with regulatory standards as well as the related gaps in knowledge among DONs, administrators, and nursing staff.

AB - Identifying older adults with heart failure at risk for hospital readmission is challenging, and risk prediction models may be improved with inclusion of telehealth factors. In the current study, demographic, clinical, telehealth, and use data for emergency department (ED) presentations, hospitalizations, and length of stay (LOS) were collected from the records of 187 Veterans with heart failure participating in a 90-day Care Coordination Home Telehealth program between September 2007 and September 2013. Heart failure-related ED visits were 17.6% and 18.2% required hospitalization with an average LOS of 7 days (range = 1 to 38 days). Binary logistic regression models failed to predict likelihood of an ED presentation or hospitalization. Poisson regression models significantly predicted hospital LOS on the factors of telehealth alerts, nurse response to alerts, advancing age, and chronic renal disease. Data collected from one telehealth program significantly contributed to heart failure-related risk prediction models and should be included in future models.

AB - Nurse managers (NMs) in long-term care supervise health care services for individuals with high acuity levels and numerous comorbidities. There is minimal research identifying NMs' skills and competencies as unit leaders within the long term care environment. The current mixed-methods study identified NMs' leadership skills and competencies. Nineteen NMs with >=5 years' long-term care management experience completed the Nurse Manager Inventory Tool and were individually interviewed. They rated their clinical skills at the competent level and their financial/strategic management skills at the novice level. All other skill categories, including leadership reflective practice, diversity, human resource leadership/management, relationship management, performance improvement, and problem solving, were rated at a competent level. Emergent interview qualitative themes included their visibility on the unit, trial and error learning, a sense of "aloneness" due to the absence of other RNs, NM position being a tough job, need for peer support, role modeling, and importance of supporting the resident through their "final journey."

PMID- 29596717 TI - Influence of Body Composition and Nutrition Parameters in Handgrip Strength: Are There Differences by Sex in Hemodialysis Patients? AB - BACKGROUND: Hemodialysis (HD) patients are vulnerable to multiple metabolic and nutrition derangements, leading to changes in body composition. Handgrip strength (HGS) has been used as a nutrition marker. We aimed to evaluate the relationship between HGS and lean tissue mass (LTM) with several parameters in HD patients and develop HGS predictive equations. METHODS: Cross-sectional study with 155 patients in HD treatment for >=3 months. Body composition was assessed through bioimpedance spectroscopy. HGS was measured with a hydraulic hand dynamometer. Biochemical parameters were evaluated. Data were analyzed by sex. RESULTS: Ninety four were men, and mean age was 64.4 +/- 14.7 years. We found positive correlation of HGS with LTM, lean tissue index, and body cell mass and negative correlation between HGS, age, and overhydration in both sexes. Serum albumin level presented a positive correlation and magnesium a negative correlation with HGS only in men. The LTM presented a positive correlation with protein intake, serum albumin level, and body cell mass and a negative correlation with age in both groups. A significant positive correlation with magnesium and a negative correlation with overhydration were observed in men. The predictability of the models was R2 = 0.618 for men and R2 = 0.500 for women. CONCLUSION: HGS is highly correlated with LTM, and both differ between sexes and are, therefore, differently correlated with the parameters studied. Body composition, overhydration, and some biochemical parameters explain changes in HGS. Predictive models including body composition and biochemical parameters may explain at least 50% of the variance of HGS. PMID- 29596718 TI - Bioelectrical Impedance Analysis-Derived Measurements in Chronic Hepatitis C: Clinical Relevance of Fat-Free Mass and Phase Angle Evaluation. AB - OBJECTIVE: Because cirrhotic patients are at high risk of malnutrition and sarcopenia, we evaluated the prevalence of low fat-free mass index (FFMI) and low phase angle (PhA) among patients with chronic hepatitis C (CHC). METHODS: In total, 135 subjects with CHC (50.4% males; mean age, 52.4 +/- 11.8 years; 65.9% noncirrhotic and 34.1% compensated cirrhotic patients) were prospectively included and evaluated by bioelectrical impedance analysis. Subjective global assessment was used to evaluate malnutrition. RESULTS: Low FFMI and low PhA were identified in 21.5% and 23.7% of the patients, respectively. Compensated cirrhotic patients had lower PhA values than those without cirrhosis. Low FFMI was associated with male sex (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.00-7.01; P = .04) and malnutrition (OR, 4.27; 95% CI, 1.42-12.90; P = .01). Low PhA was associated with cirrhosis (OR, 3.92; 95% CI, 1.56-9.86; P = .004), malnutrition (OR, 5.52; 95% CI, 1.73-17.62; P = .004), and current alcohol use (OR, 2.77; 95% CI, 1.01-7.58; P = .05). Reactance (Xc) normalized for height (H), an indicator of muscle strength, was independently associated with male sex, age, hypertension, and serum albumin. CONCLUSION: Host factors, including clinical comorbidities, lifestyle, and nutrition status, are associated with low FFMI and low PhA in noncirrhotic and in compensated cirrhotic patients with CHC. These findings highlight the relevance of evaluating body composition in patients chronically infected by hepatitis C virus independently of the stage of liver disease. PMID- 29596719 TI - Estimating Resting Energy Expenditure by Different Methods as Compared With Indirect Calorimetry for Patients With Pulmonary Hypertension. AB - BACKGROUND: For patients with pulmonary hypertension, nutrition status is an independent predictor of morbidity and mortality, and energy expenditure can be strongly influenced by lung disease. Indirect calorimetry (IC) is the gold standard for measuring resting energy expenditure (REE), this study aimed to compare the results of REE estimated by different methods with those obtained by IC for patients with pulmonary hypertension. METHODS: In this cross-sectional study (n = 34), REE was estimated by bioelectrical impedance analysis and the predictive equations of Harris-Benedict, Food and Agriculture Organization / World Health Organization, Institute of Medicine, Cunningham, Katch-McArdle, and Mifflin-St Jeor. RESULTS: Mean patient age was 47.0 +/- 14.5 years, and 76.5% were women. REE obtained with IC was strongly correlated with all other estimation methods but showed higher mean values: IC 1750.8 +/- 434.3 kcal vs bioelectrical impedance analysis, 1549.0 +/- 417.8 kcal; Harris-Benedict, 1493.1 +/- 337.0 kcal; FAO/WHO, 1536.1 +/- 345.0 kcal; Institute of Medicine, 1457.1 +/- 293.2 kcal; Cunningham, 1597.3 +/- 292.3 kcal; Katch-McArdle, 1447.7 +/- 287.0 kcal; and Mifflin-St Jeor, 1388.7 +/- 303.9 kcal. The analysis of agreement showed a clinically significant bias of approximately -255 kcal in all estimation methods when compared with IC. CONCLUSION: Although there was a strong correlation between REE estimation methods and IC, there was no agreement between them. All estimation methods underestimated energy needs by about 255 kcal for patients with pulmonary hypertension, and the Cunningham equation had the smallest difference in relation to IC.

PMID- 29596720 TI - Differential mobility spectrometry (DMS) reveals the elevation of urinary acetylcarnitine in non-human primates (NHPs) exposed to radiation. AB - Acetylcarnitine has been identified as one of several urinary biomarkers indicative of radiation exposure in adult rhesus macaque monkeys (non-human primates, NHPs). Previous work has demonstrated an up-regulated dose-response profile in a balanced male/female NHP cohort. As a contribution toward the development of metabolomics-based radiation biodosimetry in human populations and other applications of acetylcarnitine screening, we have developed a quantitative, high-throughput method for the analysis of acetylcarnitine. We employed the Sciex SelexIon DMS-MS/MS QTRAP 5500 platform coupled to flow injection analysis (FIA), thereby allowing for fast analysis times of less than 0.5 minutes per injection with no chromatographic separation. Ethyl acetate is used as a DMS modifier to reduce matrix chemical background. We have measured NHP urinary acetylcarnitine from the male cohorts that were exposed to the following radiation levels: control, 2, 4, 6, 7, and 10 Gy. Biological variability, along with calibration accuracy of the FIA-DMS-MS/MS method, indicates LOQ of 20 MUM, with observed biological levels on the order of 600 MUM and control levels near 10 MUM. There is an apparent onset of intensified response in the transition from 6 to 10 Gy. The results demonstrate that FIA-DMS-MS/MS is a rapid, quantitative technique that can be utilized for the analysis of urinary biomarker levels for radiation biodosimetry.

AB - BACKGROUND AND OBJECTIVES: Substance use disorders (SUDs) are present in up to 70% of patients with bipolar disorder (BD) and contribute to high rates of disability, morbidity, and treatment non-adherence. Despite this prevalence, few trials have investigated targeted psychosocial interventions for comorbid BD and SUDs. METHODS: Using PubMed and PsycINFO, we conducted a search of the literature up to January 2018 for psychosocial interventions targeted to patients with comorbid BD and SUDs. We identified eight total trials. Of these studies, four randomized and two open trials targeted the types of substance use (alcohol and illicit drugs) of primary concern to mood stability; the remaining two studies, both open trials, targeted smoking cessation. RESULTS: None of the randomized trials provided consistent evidence for management of both mood symptoms and substance use though integrated group therapy (IGT) demonstrated consistent beneficial effects on substance use outcomes. Other treatments showed benefit for mood symptoms without benefits for alcohol or illicit substance use. Small pilot studies of combined treatments for smoking cessation provided some initial promise. CONCLUSIONS: At present, IGT is the most-well validated and efficacious approach if substance use is targeted in an initial treatment phase. For a subsequent phase, additional psychosocial BD treatments may be needed for mood and functioning benefits. SCIENTIFIC SIGNIFICANCE: This review synthesizes the psychosocial interventions that have been conducted in comorbid BD and SUDs while also providing a perspective on which intervention elements are helpful for addressing substance use versus mood symptoms in patients with these co-occurring conditions.

AB - BACKGROUND AND OBJECTIVES: Substance use disorder (SUD) has increased among women, including military veterans, yet SUD treatment was historically designed for males. This randomized controlled trial compared 12 individual sessions of a gender-focused SUD recovery model, A Woman's Path to Recovery (WPR) to an evidence-based, non-gender-focused SUD model, 12-Step Facilitation (TSF) for 66 women veterans with current severe SUD. METHODS: The primary outcome was substance use; secondary outcomes were associated problems (e.g., psychological); coping skills, and 12-step attendance, with assessment at baseline, end-of treatment, and 3-month followup. RESULTS: Substance use decreased over time, with no difference between conditions. Decreases occurred from baseline to end-of treatment and baseline to followup and, for drug severity, also from end-of treatment to followup. Effect sizes were large for alcohol and medium otherwise. Secondary outcomes were largely consistent with this pattern of improvement. Urinalysis/breathalyzer supported self-report. Treatment attendance was 62% for WPR and 57% for TSF (not significantly different). Twelve-step group attendance, surprisingly, did not increase in either condition. DISCUSSION AND CONCLUSIONS: WPR provides a useful addition to women's SUD treatment options, with outcomes no different than an established evidence-based model, TSF. Both showed positive impact on substance use and related areas. Our lack of differences based on gender-focus may reflect women veterans being acculturated to a male military environment. Limitations include lack of an untreated control, a sample limited to veterans, and use of a large effect size for power assumptions. SCIENTIFIC SIGNIFICANCE: This is the first RCT of a gender-focused approach for women veterans with SUD. (Am J Addict 2018;27:210-216).

Despite the paucity of information about its long-term health effects, salvia is readily available and generally portrayed as a safe non-addictive substance. METHODS AND RESULTS: We report on two patients who presented with an enduring and pervasive pattern of salvia use. DISCUSSION AND CONCLUSIONS: Evaluating patients for salvia use during clinical assessment is strongly encouraged, especially among young polysubstance users. SCIENTIFIC SIGNIFICANCE: Clinicians should be mindful of the multifaceted psychiatric effects of salvia, including the potential for a use disorder. (Am J Addict 2018;27:163-165).

AB - BACKGROUND AND OBJECTIVES: Opioid use disorder (OUD) is a chronic condition with potentially severe health and social consequences. Many who develop moderate to severe OUD will repeatedly seek treatment or interact with medical care via emergency department visits or hospitalizations. Thus, there is an urgent need to develop feasible and effective approaches to help persons with OUD achieve and maintain abstinence from opioids. Treatment that includes one of the three FDA approved medications is an evidence-based strategy to manage OUD. The purpose of this review is to address practices for managing persons with moderate to severe OUD with a focus on opioid withdrawal and naltrexone-based relapse-prevention treatment. METHODS: Literature available on PubMed was used to review the evolution of treatment strategies from the 1960s onward to manage opioid withdrawal and initiate treatment with naltrexone. RESULTS: Emerging practices for extended-release naltrexone induction include the use of agonist tapers and adjuvant medications. Clinical challenges frequently encountered when initiating this therapy include managing withdrawal and ongoing opioid use during treatment. Clinical factors may inform decisions regarding patient selection and length of naltrexone treatment, such as recent opioid use and patient preferences. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Treatment strategies to manage opioid withdrawal have evolved, but many patients with OUD do not receive medication for the prevention of relapse. Clinical strategies for induction onto extended release naltrexone are now available and can be safely and effectively implemented in specialty and select primary care settings.

AB - BACKGROUND AND OBJECTIVES: Much debate exists surrounding Arnett's theory of emerging adulthood in terms of its breadth and application. Researchers have attempted to capture dimensions of emerging adulthood (eg, experimentation, negativity/instability, other-focus, self-focus, and feeling in-between) through self report assessment, using variations of the Inventory of the Dimensions of Emerging Adulthood or IDEA. Results from studies investigating this relationship have been mixed. We conducted a meta-analysis on the association between substance use and the IDEA. METHOD: Data were extracted to calculate correlational associations with substance use as well as typical moderators found in the literature. Twelve studies were meta-analyzed. RESULTS: We found small associations (range: rho = -.03 to .15; d = .06 to 30) between the IDEA scores and substance use. We found higher severity (dependence diagnosis) of participants yielded larger associations across all dimensions (rho = .16), and proportion of college students to be a subscale-specific moderator (experimentation, negativity/instability, other-focus, self-focus, and feeling in between). Alcohol use outcomes also provided larger subscale-specific associations (experimentation, negativity/instability, other-focus, self-focus). CONCLUSIONS: The dimensions of emerging adulthood may be less effective in predicting substance use among non-college samples and those studies focusing on drug use. Further research should prioritize exploring variation in the transition to emerging adulthood among non-college samples and the longitudinal associations between IDEA and substance use. SCIENTIFIC SIGNIFICANCE: Important contributions include the modest association between IDEA and substance use as well as specific participant characteristics that amplify or mitigate the association between IDEA and substance use.

The main cause is an irritant reaction to urine and feces, which is facilitated by the occlusive conditions under the diaper, leading to hyperhydration of the stratum corneum (diaper dermatitis). In addition, diaper pressure and friction can increase the risk of skin inflammation, which also opens the skin up to other irritant agents, allergens, and infectious agents, such as candida albicans. However, a variety of diseases are associated with inflammation of the skin in the diaper region, therefore the term "diaper dermatitis" is merely descriptive and does not reflect anything about the etiopathogenesis. The term diaper dermatitis refers only to an inflammation in the diapering area and should not be automatically equated with reactions to diapers. Making the correct diagnosis requires a thorough examination of the skin in its entirety and a detailed report of the patient's medical and family history. Once a specific pattern is identified, a precise diagnosis, and an appropriate therapy, can be determined. PMID- 29596731 TI - Prevention and treatment of diaper dermatitis. AB - Diaper dermatitis (DD) is one of the most common skin conditions that infants suffer from and their caregivers manage in the first months post-birth. As such, questions of effective prevention and treatment of the condition often arise. Nonmedical skincare practices that support healthy skin barrier function can prevent DD manifestation or alleviate the condition in many cases. The usage of barrier emollients and improved diaper technology contributes to keeping moisture and irritants away from an infant's delicate skin. This paper addresses facts behind commonly asked questions from caregivers regarding DD and discusses effective measures to prevent and treat the condition.

PMID- 29596733 TI - Skin barrier in the neonate. AB - The purpose of this review is to focus on determinants of skin barrier function in neonates at molecular and cellular levels. The skin barrier is critical in terms of water and gas exchanges during fetal life and undergoes rapid changes at birth, followed by a progressive maturation. Consequences of skin barrier disruption can be extremely detrimental or lethal, as shown in severe genetic epidermal defects. In this context, the fine-tuned rapid adaptation from a liquid to a gaseous milieu is not fully understood. The stratum corneum provides an air liquid barrier, tight junctions in the granular layer provide a liquid-liquid barrier, aquaporins represent a plumbing system for water-glycerol as well as gas exchanges, and Langerhans cells are central to the immunological barrier. Acid mantle formation is essential for appropriate interaction between the skin and microbial symbionts. Temperature and pH regulate the key enzyme activities responsible for the integrity of the stratum corneum. Skin barrier permeability can be assessed noninvasively and simply with miniaturized devices measuring transepidermal water loss, where water flow is faster in cases of a damaged or functionally premature barrier. New avenues for therapeutic skin barrier research in neonates include a better delineation of the maturation of aquaporins in water balance and gas exchanges from fetal to neonatal life and a better understanding of the role of vernix caseosa, in particular, for the implantation of a healthy microbiote. Practical applications should be derived for caring for infant skin, particularly in fragile zones, such as the diaper area.

AB - A dual cross-linking strategy was developed to answer the urgent need for fatigue resistant, cytocompatible, and in situ forming tough hydrogels. Clickable, yet calcium-binding derivatives of alginate were synthesized by partial substitution of its carboxyl functionalities with furan, which could come into Diels-Alder click reaction with maleimide end groups of a four arm poly(ethylene glycol) cross-linker. Tuning the cooperative viscoelastic action of transient ionic and permanent click cross-links within the single network of alginate provided a soft tough hydrogel with a set of interesting features: (i) immediate self-recovery under cyclic loading, (ii) highly efficient and autonomous self-healing upon fracture, (iii) in situ forming ability for molding and minimally invasive injection, (iv) capability for viable cell encapsulation, and (v) reactivity for on-demand biomolecule conjugation. The facile strategy is applicable to a wide range of natural and synthetic polymers by introducing the calcium binding and click reacting functional groups and can broaden the use of tough hydrogels in load-bearing, cell-laden applications such as soft tissue engineering and bioactuators. PMID- 29596740 TI - Formation of Particulate Matter from the Oxidation of Evaporated Hydraulic Fracturing Wastewater. AB - The use of hydraulic fracturing for production of petroleum and natural gas has increased dramatically in the past decade, but the environmental impacts of this technology remain unclear. Experiments were conducted to quantify airborne emissions from 12 samples of hydraulic fracturing flowback wastewater collected in the Permian Basin, as well as the photochemical processing of these emissions leading to the formation of particulate matter (PM). The concentration of total volatile carbon (hydrocarbons evaporating at room temperature) averaged 29 mg of carbon per liter. After photochemical oxidation under high NO x conditions, the amount of organic PM formed per milliliter of wastewater evaporated averaged 24 MUg; the amount of ammonium nitrate formed averaged 262 MUg. Based on the mean PM formation observed in these experiments, the estimated formation of PM from evaporated flowback wastewater in the state of Texas is in the range of estimated PM emissions from diesel engines used in oil rigs. Evaporation of flowback wastewater, a hitherto unrecognized source of secondary pollutants, could significantly contribute to ambient PM concentrations.

AB - Optogenetic tools provide a new and efficient way to dynamically program gene expression with unmatched spatiotemporal precision. To date, their vast potential remains untapped in the field of cell-free synthetic biology, largely due to the lack of simple and efficient light-switchable systems. Here, to bridge the gap between cell-free systems and optogenetics, we studied our previously engineered one component-based blue light-inducible Escherichia coli promoter in a cell-free environment through experimental characterization and mathematical modeling. We achieved >10-fold dynamic expression and demonstrated rapid and reversible activation of the target gene to generate oscillatory response. The deterministic model developed was able to recapitulate the system behavior and helped to provide quantitative insights to optimize dynamic response. This in vitro optogenetic approach could be a powerful new high-throughput screening technology for rapid prototyping of complex biological networks in both space and time without the need for chemical induction.

AB - We present herein the first visible-light-driven hydrocarboxylation as well as carbocarboxylation of alkynes using CO2 via an iridium/cobalt dual catalysis. Such transformations provide access to various pharmaceutically important heterocycles in a one-pot procedure from readily available alkynes. Coumarins, 2 quinolones, and 2-benzoxepinones were directly accessed through a one-pot alkyne hydrocarboxylation/alkene isomerization/cyclization sequence in which the Ir photocatalyst serves a dual role to promote single-electron transfer in alkyne hydrocarboxylation and energy transfer in the subsequent alkene isomerization. Moreover, an unprecedented cobalt carboxylation/acyl migration cascade enables alkyne difunctionalization to introduce gamma-hydroxybutenolides with high efficiency. We expect that this cascade strategy will inspire new perspectives for alkyne and alkene difunctionalization. PMID- 29596744 TI - CADS: CRISPR/Cas12a-Assisted DNA Steganography for Securing the Storage and Transfer of DNA-Encoded Information. AB - Because DNA has the merit of high capacity and complexity, DNA steganography, which conceals DNA-encoded messages, is very promising in information storage. The classical DNA steganography method hides DNA with a "secret message" in a mount of junk DNA, and the message can be extracted by polymerase chain reaction (PCR) using specific primers (key), followed by DNA sequencing and sequence decoding. As leakage of the primer information may result in message insecurity, new methods are needed to better secure the DNA information. Here, we develop a pre-key by either mixing specific primers (real key) with nonspecific primers (fake key) or linking a real key with 3'-end redundant sequences. Then, the single-stranded DNA (ssDNA) trans cleavage activity of CRISPR/Cas12a is employed to cut a fake key or remove the 3'-end redundant sequences, generating a real key for further information extraction. Therefore, with the Cas12a-assisted DNA steganography method, both storage and transfer of DNA-encoding data can be better protected. PMID- 29596746 TI - Noncovalent Interactions Descriptor Based on the Source Function of Individual Localized Molecular Orbitals in Whole Space. AB - The partitioning of total electron density into localized molecular orbitals (LMOs) within the source function framework is presented as an exploit useful to the characterization of noncovalent interactions. The resulting approach uses only a converged LMO base as input and does not require grid data handling or numerical integration, making it viable for the study of large systems. Tests conducted on a series of prototypical hydrogen and halogen bonds demonstrate that this descriptor retrieves chemically intuitive interaction motifs beyond the classical two-center picture. Advantages and disadvantages of different localization schemes are discussed in terms of their peculiar description of sigma-pi mixing and in terms of their inherent basis set dependence.

AB - In our quest for new antibiotics able to address the growing threat of multidrug resistant infections caused by Gram-negative bacteria, we have investigated an unprecedented series of non-quinolone bacterial topoisomerase inhibitors from the Sanofi patrimony, named IPYs for imidazopyrazinones, as part of the Innovative Medicines Initiative (IMI) European Gram Negative Antibacterial Engine (ENABLE) organization. Hybridization of these historical compounds with the quinazolinediones, a known series of topoisomerase inhibitors, led us to a novel series of tricyclic IPYs that demonstrated potential for broad spectrum activity, in vivo efficacy, and a good developability profile, although later profiling revealed a genotoxicity risk. Resistance studies revealed partial cross resistance with fluoroquinolones (FQs) suggesting that IPYs bind to the same region of bacterial topoisomerases as FQs and interact with at least some of the keys residues involved in FQ binding.

AB - We use ab initio molecular dynamics simulations to study the adsorption of thin water films with 1 and 2 ML coverage on anatase TiO2 (001) nanotubes. The nanotubes are modeled as 2D slabs, which consist of partially constrained and partially relaxed structural motifs from nanotubes. The effect of anion doping on the adsorption is investigated by substituting O atoms with N and S impurities on the nanotube slab surface. Due to strain-induced curvature effects, water adsorbs molecularly on defect-free surfaces via weak bonds on Ti sites and H bonds to surface oxygens. While the introduction of an S atom weakens the interaction of the surface with water, which adsorbs molecularly, the presence of an N impurity renders the surface more reactive to water, with a proton transfer from the water film and the formation of an NH group at the N site. At 2 ML coverage, a further surface-assisted proton transfer takes place in the water film, resulting in the formation of an OH- group and an NH2+ cationic site on the surface.

AB - Experimental and theoretical evidence is reported for a rare type I dyotropic rearrangement involving a [1,2]-alkene shift, leading to the regio- and stereospecific ring contraction of bromocycloheptenes. This reaction occurs under mild conditions, with or without a Lewis acid catalyst. DFT calculations show that the reaction proceeds through a nonclassical carbocation-anion pair, which is crucial for the low activation barrier and enantiospecificity. The chiral cyclopropylcarbinyl cation may be a transition state or an intermediate, depending on the reaction conditions.

AB - A novel poly( N-isopropylacrylamide) (PNIPAM) hydrogel containing different photosensitizers (protoporphyrin IX (PpIX), pheophorbide a (Pba), and protoporphyrin IX dimethyl ester (PpIX-DME)) has been synthesized with a significant improvement in water solubility and potential for PDT applications compared to the individual photosensitizers (PSs). Conjugation of PpIX, Pba, and PpIX-DME to the poly( N-isopropylacrylamide) chain was achieved using the dispersion polymerization method. This study describes how the use of nanohydrogel structures to deliver a photosensitizer with low water solubility and high aggregation tendencies in polar solvents overcomes these limitations. FT IR spectroscopy, UV-vis spectroscopy, 1H NMR, fluorescence spectroscopy, SEM, and DLS analysis were used to characterize the PNIPAM-photosensitizer nanohydrogels. Spectroscopic studies indicate that the PpIX, Pba, and PpIX-DME photosensitizers are covalently conjugated to the polymer chains, which prevents aggregation and thus allows significant singlet oxygen production upon illumination. Likewise, the lower critical solution temperature was raised to ~44 degrees C in the new PNIPAM-PS hydrogels. The PNIPAM hydrogels are biocompatible with >90% cell viability even at high concentrations of the photosensitizer in vitro. Furthermore, a very sharp onset of light-dependent toxicity for the PpIX-based nanohydrogel in the nanomolar range and a more modest, but significant, photocytotoxic response for Pba-PNIPAM and PpIX-DME-PNIPAM nanohydrogels suggest that the new hydrogels have potential for applications in photodynamic therapy.

AB - The performance of photochemical reactors is governed by the spatial distribution of radiant energy within the irradiated region of the reactor. Ray tracing has been widely used for simulation of lighting systems. The central hypothesis of this work was that ray tracing can provide accurate simulations of fluence rate fields within ultraviolet (UV) photoreactors by accounting for the physical and optical phenomena that will govern fluence rate fields in UV photoreactors. Ray tracing works by simulating the behavior of a large population of rays emanating from a radiation source to describe the spatial distribution of radiant energy (i.e., fluence rate) within a system. In this study, fluence rate calculations were performed using commercial ray tracing software for three basic UV reactors, each with a single low-pressure Hg lamp. Fluence rate calculations in the ray tracing program were based on the formal definition of fluence rate, calculated as the incident radiant power from all directions on a small spherical receptor, divided by the cross-sectional area of that sphere. The results of this study demonstrate that ray tracing can provide predictions of fluence rate in UV radiative systems that are close to experimental measurements and the predictions of other numerical methods. PMID- 29596751 TI - Breastfeeding Versus Bottle Feeding on Malocclusion in Children: A Meta-Analysis Study. AB - BACKGROUND: Breastfeeding plays an important role in child health. However, there are doubts about its influence on malocclusions. Systematic reviews have yielded contradictory results. Research aim: This study aimed to investigate whether the type and duration of breastfeeding are associated with malocclusions in primary teething. METHODS: The review strategy included several electronic databases, lists of references, reviews, dissertation and thesis websites, experts, and other relevant documents. Published and unpublished observational studies ( N = 42) were reviewed using the Participants (children), Interventions (breastfeeding), Comparisons (bottle feeding), Outcomes (malocclusion), and Study design (observational) strategy, without restrictions on language or locale. Information about the authors, publication year, country of study, setting, study design, sample size, age, type and duration of exclusive and mixed breastfeeding, and malocclusions was recorded by two blinded evaluators. Quantitative meta analysis ( N = 30) of the studies with available data was performed. RESULTS: Breastfeeding was a protective factor against malocclusions. The odds of association increased with breastfeeding duration. Irrespective of duration, breastfeeding had a protective association with open bite. For those who were breastfed for up to 6 months, breastfeeding protected against overjet, open bite, posterior crossbite, and crowding. Breastfeeding for 12 months or longer was associated with lower odds of overjet, open bite, and posterior crossbite. Breastfeeding exclusively for 6 months was also a protective factor against malocclusions. However, studies on this subject presented low quality, statistical heterogeneity, and only unadjusted measures of association in most of the cases. CONCLUSION: Breastfeeding beneficially affects primary occlusion when practiced for at least 6 months.

PMID- 29596754 TI - Severe Periodontitis Is Associated with Myocardial Infarction in Females. AB - The aim of the present study was to test the hypothesis that there is a sex difference in the association between periodontitis (PD) and a first myocardial infarction (MI). The analysis in the case-control study was based on 785 patients (147 females and 638 males) with a first MI and 792 matched controls (147 females and 645 males), screened for cardiovascular risk factors and subjected to a panoramic dental X-ray. Periodontal status was defined by alveolar bone loss and diagnosed as no PD (>=80% remaining alveolar bone), mild to moderate PD (66% to 79%), or severe PD (<66%). Logistic regression was used when analyzing PD as a risk factor for MI, adjusting for age, smoking, diabetes, education, and marital status. The mean age was 64 +/- 7 y for females and 62 +/- 8 y for males. Severe PD was more common in female patients than female controls (14 vs. 4%, P = 0.005), with an increased risk for severe PD among female patients with a first MI (odds ratio [OR] = 3.92, 95% confidence interval [CI] =1.53 to 10.00, P = 0.005), which remained (OR = 3.72, 95% CI = 1.24 to 11.16, P = 0.005) after adjustments. Male patients had more severe PD (7% vs. 4%; P = 0.005) than male controls and an increased risk for severe PD (OR = 1.88, 95% CI = 1.14 to 3.11, P = 0.005), but this association did not remain following adjustment (OR = 1.67, 95% CI = 0.97 to 2.84, NS). Severe PD was associated with MI in both females and males. After adjustments for relevant confounders, this association did, however, remain only in females. These data underline the importance of considering poor dental health when evaluating cardiovascular risk, especially in females. PMID- 29596755 TI - Association Between Intimate Partner Violence and Breastfeeding Duration: Results From the 2004-2014 Pregnancy Risk Assessment Monitoring System. AB - BACKGROUND: Intimate partner violence is a major public health problem that disproportionately affects women. Current literature investigating the relationship between intimate partner violence and breastfeeding is inconsistent. Research aim: This study aims to investigate the relationship between physical intimate partner violence that occurs in the preconception or prenatal period and any breastfeeding duration. METHODS: Data from the retrospective, cross-sectional 2004-2014 Pregnancy Risk Assessment Monitoring System were analyzed ( N = 195,264). The outcome, breastfeeding duration, was categorized as never breastfed, breastfed 8 weeks or less, and breastfeed more than 8 weeks. Multinomial logistic regression was used to obtain crude and adjusted odds ratios and 95% confidence intervals. RESULTS: Approximately 6% ( n = 11,766) of survey respondents reported preconception and/or prenatal intimate partner violence, and 36.3% ( n = 67,667) of women reported never breastfeeding. The odds of discontinuing breastfeeding before 8 weeks were 18% higher among women who reported experiencing abuse 12 months before pregnancy compared with women who did not report intimate partner violence (adjusted odds ratio = 1.18; 95% confidence interval [1.01, 1.37]). All other estimates showed an overlapping 95% confidence interval. CONCLUSION: Breastfeeding is essential in improving maternal and child health; however, women in abusive relationships may face additional barriers to breastfeeding. Further research is needed to better understand the impact of violence on breastfeeding behaviors to inform healthcare practices and interventions. PMID- 29596756 TI - Validation of the Chinese Version of the Australian Breastfeeding Attitude Questionnaire. AB - BACKGROUND: The Australian Breastfeeding Knowledge and Attitude Questionnaire Short Form (ABKAQ-SF) was designed to measure breastfeeding knowledge and attitudes of health professionals. To date, a Chinese version of the attitude component of the ABKAQ-SF (ABAQ) is not yet available and has not been cross validated with nursing students. Research aims: This study aimed to examine (a) the psychometric properties of the ABAQ and (b) group differences and responsiveness of the revised 12-item ABAQ (ABAQ12) among nursing students in Taiwan. METHODS: Using a cross-sectional two-cohort study design, nursing students in Years 2 and 3 of a 4-year bachelor of nursing program ( N = 205) completed the Chinese version of the ABAQ, translated using forward and backward translations. Content validity, internal consistency reliability, construct validity, group differences, and responsiveness of the Chinese version of the ABAQ were assessed. RESULTS: Using the principal axis factoring procedure of exploratory factor analysis to examine the dimensionality of the ABAQ, a one component structure was identified. Six items were deleted, based on the average interitem correlation (< 0.2), low corrected item-total correlation (< 0.35), and low factor loading (< 0.3). Confirmatory factor analysis of the ABAQ12 supported a one-factor solution, with good overall model fit (goodness-of-fit index = 0.949, Tucker-Lewis index = 0.951, comparative fit index = 0.965, root mean square error of approximation = 0.042). Responsiveness of the ABAQ12 scores indicated a positive change in breastfeeding attitude between the pre- and postclinical placement period. CONCLUSION: The Chinese version of the ABAQ12 is valid, reliable, and responsive and is suitable for assessing the breastfeeding attitudes of nursing students in the Taiwanese higher education settings. PMID- 29596758 TI - Social Justice and Lactation. PMID- 29596759 TI - Breastfeeding, Antidepressants, and Depression in the Mercy Pregnancy and Emotional Well-Being Study. AB - BACKGROUND: Depression is consistently shown to predict lower rates of breastfeeding. In a handful of studies, breastfeeding has predicted lower depression symptoms. However, studies demonstrating the latter are limited in their measurement of both depression and breastfeeding and have not followed participants from pregnancy across the postpartum period. Research Aim: The primary aim of this study was to describe breastfeeding intentions and behaviors for the first 12 months postpartum among nonmedicated depressed, antidepressant exposed, and control participants. The secondary aim was to examine group differences in the association between depressive symptoms and breastfeeding duration up to 12 months postpartum. METHODS: First-trimester women ( n = 212) were recruited into a prospective longitudinal study. Depressive disorders at baseline were diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders, and depressive symptoms were measured at the first and second trimesters and 6 and 12 months postpartum using the Edinburgh Postnatal Depression Scale. Breastfeeding duration, support from family and employers, and perceptions of participants' experience were measured. RESULTS: Depressed women and antidepressant-exposed women reported a trend toward lower rates of intention, initiation, and duration, but this did not reach statistical significance. There was a statistically significant difference on depressive symptoms for women taking antidepressants during pregnancy, compared with controls, when they continued to breastfeed for 12 months postpartum. CONCLUSIONS: This study did not find a strong association between depression or antidepressant use and intention to breastfeed, partner breastfeeding support, or initiation or duration of breastfeeding. However, for women who took antidepressants, there was evidence that breastfeeding for 12 months was associated with lower depressive symptoms.

PMID- 29596761 TI - Vitamin D and the Breastfeeding Infant: Family Medicine Clinicians' Knowledge, Attitudes, and Practices. AB - BACKGROUND: The American Academy of Pediatrics and the National Academy of Medicine recommend vitamin D supplementation for breastfeeding infants. However, compliance with this recommendation is poor. Maternal supplementation with vitamin D is a safe and effective alternative to achieving vitamin D sufficiency in breastfeeding infants, and mothers have indicated a preference for self supplementation over infant supplementation. Research aim: We sought to explore Family Medicine clinicians' knowledge, attitudes, and practices regarding vitamin D supplementation recommendations for breastfeeding dyads. METHODS: Fifty-six Family Medicine clinicians (including faculty physicians, resident physicians, and nurse practitioners/physician assistants) completed an online, anonymous survey regarding their knowledge and practices concerning vitamin D supplementation for breastfeeding infants. RESULTS: The vast majority of clinicians (92.9%) correctly identified the American Academy of Pediatrics' 2008 recommended dose for vitamin D supplementation in breastfeeding infants and estimated recommending vitamin D supplementation of exclusively breastfeeding infants 70.1% of the time. If all options were equivalent, clinicians would prefer to offer maternal or infant supplementation (50%) or maternal supplementation (37.5%) over infant supplementation (12.5%). Most (69.6%) preferred daily over monthly supplementation regimens. CONCLUSION: Family Medicine clinicians are knowledgeable regarding current recommendations for vitamin D supplementation in breastfeeding infants. They are also open to recommending maternal supplementation or offering parents a choice of maternal or infant vitamin supplementation.

Cochrane Database Syst Rev. 2015;4:CD009534.] AB - Asymptomatic bacteriuria is frequently detected in women aged up to 60 years, patients with diabetes and elderly patients. The benefit of antibiotic treatment for this condition is controversial. The objective of this Cochrane systematic review was to assess the effectiveness and safety of antibiotic treatment for asymptomatic bacteriuria in adults. A systematic review of the literature up to 24 February 2015 was performed using the Cochrane Renal Group's Specialised Register. Randomised controlled trials (RCTs) and quasirandomised controlled trials comparing antibiotics to placebo or no treatment for asymptomatic bacteriuria in adults were included. The outcomes of interest were the development of symptomatic urinary tract infection, complications, death, adverse events, development of antibiotic resistance, bacteriological cure, and decline in kidney function. Nine studies (1614 participants) were included in this review. The incidence of symptomatic urinary tract infection, complications or death was similar between groups. Antibiotic use was significantly associated with bacteriological cure and an increase in minor adverse events. No decline in kidney function was observed with any one of the treatments. According to the results of the studies included in this revision, authors have concluded that there is no clinical benefit in treating asymptomatic bacteriuria in adults. PMID- 29596767 TI - Challenges of Ageing in Portugal: Data from the EpiDoC Cohort. AB - INTRODUCTION: Portuguese adults have a long lifespan, but it is unclear whether they live a healthy life in their final years. We aimed to determine the prevalence of multimorbidity and characterize lifestyle and other health outcomes among older Portuguese adults. MATERIAL AND METHODS: We performed a cross sectional evaluation of 2393 adults, aged 65 and older, during the second wave of follow-up of the EpiDoC cohort, a population-based study involving long-term follow-up of a representative sample of the Portuguese population. Subjects completed a structured questionnaire during a telephone interview. Socioeconomic, demographic, lifestyle behaviours, chronic diseases, and health resources consumption were assessed. Cluster analysis was done to identify dietary patterns. Descriptive and analytic analysis was performed to estimate multimorbidity prevalence and its associated factors. RESULTS: Multimorbidity prevalence among older adults was 78.3%, increased with age strata (72.8% for 65 69 years to 83.4% for >= 80 years), and was highest in Azores (84.9%) and Alentejo (83.6%). The most common chronic diseases were hypertension (57.3%), rheumatic disease (51.9%), hypercholesterolemia (49.4%), and diabetes (22.7%). Depression symptoms were frequent (11.8%) and highest in the oldest strata. The mean health-related quality of life (EQ-5D-3L) score was 0.59 +/- 0.38. Hospitalization in the previous 12 months was reported by 25.8% of individuals. Overall, 66.6% of older adults were physically inactive. 'Fruit and vegetables dietary pattern' was followed by 85.4% of individuals; however, regional inequalities were found (69% in Azores). Obesity prevalence was 22.3% overall and was highest among Azoreans (33%). CONCLUSION: The high prevalence of multimorbidity, combined with unhealthy lifestyle behaviours, suggests that the elderly populationconstitutes a vulnerable group warranting dedicated intervention. PMID- 29596768 TI - Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-Cog): Normative Data for the Portuguese Population. AB - INTRODUCTION: The Alzheimer's Disease Assessment Scale - Cognitive Subscale is a brief battery developed to assess cognitive functioning in Alzheimer's disease that encompasses the core characteristics of cognitive decline (e.g. memory, language, praxis, constructive ability and orientation). The early detection, as well as the monitoring of cognitive decline along disease progression, is extremely important in clinical care and interventional research. The main goals of the present study were to analyze the psychometric properties of the Portuguese version of the Alzheimer's Disease Assessment Scale - Cognitive Subscale, and to establish normative values for the Portuguese population. MATERIAL AND METHODS: The Portuguese version of Alzheimer's Disease Assessment Scale - Cognitive Subscale was administered to 223 cognitively healthy participants according to a standard assessment protocol consisting of the Mini Mental State Examination, the Montreal Cognitive Assessment and the Adults and Older Adults Functional Assessment Inventory. Normal performance on the assessment protocol was the inclusion criteria for the study. RESULTS: The Alzheimer's Disease Assessment Scale - Cognitive Subscale revealed good psychometric properties when used in the Portuguese population. Age was the main predictor of the Alzheimer's Disease Assessment Scale - Cognitive Subscale total score (R2 = 0.123), whereas the influence of education level was lower (R2 = 0.027). These two variables explained 14.4% of the variance on the Alzheimer's Disease Assessment Scale - Cognitive Subscale scores and were used to stratify the normative values for the Portuguese population presented here. CONCLUSION: On the total sample, the average total score in the Alzheimer's Disease Assessment Scale - Cognitive Subscale was 6 points. The normative data were determined according to age and educational level as these were the sociodemographic variables that significantly contributed to the prediction of the Alzheimer's Disease Assessment Scale - Cognitive Subscale total scores, explaining 14.4% of their variance. The normative data are of the utmost importance to ensure proper use of this battery in Portugal. PMID- 29596769 TI - [Smoking Cessation after Bladder Cancer Diagnosis]. AB - INTRODUCTION: Smoking is an important risk factor for the development, recurrence and progression of bladder cancer. Our aim was to analyze smoking habits after diagnosis in bladder cancer patients. Additionally, we evaluated patient knowledge about smoking as a risk factor and the urologist role in promoting abstinence. MATERIAL AND METHODS: A cross-sectional, observational and descriptive study was performed in bladder cancer patients, diagnosed between January 2013 and September 2015 (n = 160) in Braga Hospital, in Portugal. RESULTS: Smoking history was present in 71.9% of the sample, with 21.9% current smokers, (40.7% of abstinence after diagnosis). Smoking was acknowledged as a risk factor by 74.4% of the sample, with only 51.3% of ever smokers and 24.4% of non-smokers recognizing smoking as the leading risk factor (p = 0.008). The presence of other household smokers were significantly higher in patients who continued smoking (40%) than in ex-smokers after diagnosis (4.2%) (p = 0.005). The majority of smokers at diagnosis (83.1%) were advised to quit by their urologist, but only one smoker (1.7%) was offered any specific intervention to aid in cessation. DISCUSSION: Smoking is not recognized as the leading risk factor for bladder cancer. This limited awareness, associated with the known difficulties in quitting smoking and the observed lack of smoking cessation interventions, may account for the high current smoking prevalence, albeit in line with other studies. CONCLUSION: This study highlights the need for efficient smoking cessation programs directed to bladder cancer patients. PMID- 29596770 TI - Children Who Leave the Emergency Department Without Being Seen: Why Did They Leave and What Would Make Them Stay? AB - INTRODUCTION: Children who visit emergency departments and leave without being seen represent a multifactorial problem. We aimed to compare the sociodemographic characteristics of children who left and of those who did not leave, as well as to evaluate parental reasoning, subsequent use of medical care and patient outcome. MATERIAL AND METHODS: This was a prospective case-control study of a random sample of children who left without being seen and their matched controls from an emergency department during a three-month period. We performed a phone questionnaire to obtain information concerning reasons for leaving, patient outcomes and general feedback. RESULTS: During the study period, 18 200 patients presented to the emergency department, of whom 92 (0.5%) left without being seen. Fifty-five (59.8%) completed the questionnaire and there were 82 controls. The most common reasons for leaving were 'excessive waiting time' (92.7%) and 'problem could wait' (21.8%). A significantly higher number of patients who left sought further medical care (78.2% vs 11%) but they did not experience higher levels of unfavourable outcomes. DISCUSSION: The waiting time seems to be the major factor that drives the decision to leave. The fact that parents felt safe in leaving and the low level of adverse outcomes highlights the low-acuity nature of the majority of patients who leave. CONCLUSION: Reducing the waiting times may be the logical strategic mean to decrease the rates of patients who leave without being seen. However, our data seems to indicate that the concerns surrounding clinical outcome after leaving may be partly unwarranted. PMID- 29596771 TI - [The Road towards the Responsible and Safe Legalization of Cannabis Use in Portugal]. AB - INTRODUCTION: Recently, the world has seen examples of the legalization of cannabis for recreational purposes. Due to the diversity of experiences in progress, it is urgent to analyze the impacts of this legalization, from a public health perspective. Therefore, this article aims to review the accumulated knowledge in the states and countries where the use of cannabis is legal and to ponder over the relevance of starting a similar path towards legalization in Portugal, thus supporting political decisions to be properly informed and evidence-based. MATERIAL AND METHODS: An extensive literature review was performed using databases and scientific journals, such as PubMed, as well as the search of institutional documentation, including the EMCDDA and SICAD. RESULTS: The gathered information provided insights and enabled assessment of (1) the acute and chronic effects of cannabis use on health, (2) the Portuguese situation related to cannabis and (3) the processes and lessons learned after the legalization of cannabis in other countries or states. Given the above, and according to the data presented, the authors argue for a safe and responsible strategy towards the legalization of cannabis use in Portugal. In accordance, a set of concrete proposals are presented. DISCUSSION: From a public health perspective, it is assumed that the interest of this proposal is to reduce the problematic use of cannabis, to effectively fight against illicit drug trafficking and drug-related crime, as well as health promotion and prevention of addictions and other adverse health impacts. This article reveals that the effects of legalization might, contrary to general beliefs, generate positive results with respect to these aims, given that there will be greater control on the market, price, quality, and information - to name a few - if implementation occurs with proper consideration and definition. CONCLUSION: The debate on the responsible and safe legalization of cannabis use in Portugal should be open and promoted, based on a public health perspective.

We report the case of a 73-year-old woman who presented with edema and erythema of her right upper eyelid. Biomicroscopic examination revealed a tick firmly attached to the eyelid margin. The tick was successfully removed using fine tweezers, and within a few days, the patient had fully recovered without sequelae. Ticks are a threat to public health as they are known vectors of numerous infectious agents responsible for serious pathologies such as Lyme disease. Ticks may also induce cutaneous local reactions, and more rarely, tick paralysis. Since morbidity increases substantially with the duration of the infestation, the tick should be completely removed as soon as possible, and patients should be aware about possible signs of tick related diseases.

AB - The emphysematous pyelonephritis is a uncommon and potentially fatal entity. The recognition of this condition enables the early correct management of patients. Diabetes and ureteral obstruction are the main risk factors identified. We present the case of a patient with no relevant risk factors or prior medical history, in which the reason of admission to the emergency department was back pain, eventually evolving into septic shock in the early hours. The imaging tests identified the presence of peri-renal and subcutaneous gas which guided the medical team to the right diagnosis (emphysematous pyelonephritis secondary to fistulized urothelial neoplasia) and the optimal surgical treatment. However, in the post-operative period the patient died, as the clinical condition and laboratory test results performed during the admission were predicting. It should also be mentioned that this same case illustrated a bacteraemia by Sphingomonas Paucimobilis (acquired in the community) with cavitated damage to lungs (probable septic embolism).

PMID- 29596784 TI - Contraceptive use by disability status: new national estimates from the National Survey of Family Growth. AB - OBJECTIVE: The objective was to determine population-based estimates of use of contraception among women 15-44 years of age in the United States by disability status. STUDY DESIGN: We examined the relationship between disability status and use of contraception among 7505 women at risk of unintended pregnancy using data from the 2011-2015 National Survey of Family Growth. RESULTS: After examining the full distribution of contraceptive method use by disability status, we found that disability status was significantly associated with differences in three categories of use: female sterilization, the oral contraceptive pill and nonuse of contraception. Multivariate analysis shows that use of female sterilization was higher among women with cognitive disabilities (aOR=1.54, 95% CI=1.12-2.12) and physical disabilities (aOR=1.59, CI=1.08-2.35) than for those without disabilities after controlling for age, parity, race, insurance coverage and experience of unintended births. Use of the pill was less common among women with physical disabilities than for those without disabilities (aOR=0.57, CI=0.40 0.82). Finally, not using a method was more common among women with cognitive disabilities (aOR=1.90, CI=1.36-2.66). CONCLUSIONS: Self-reported cognitive disabilities ("serious difficulty concentrating, remembering or making decisions"), as well as physical disabilities, are significant predictors of contraceptive choices after controlling for several known predictors of use. IMPLICATIONS: The patterns found here suggest that screening for self-reported cognitive and physical disabilities may allow health care providers to tailor counseling and sex education to help women with disabilities prevent unintended pregnancy and reach their family size goals.

Data on the relation of diabetes and the occurrence and prognosis of cardiogenic shock postacute myocardial infarction are scant. METHODS: Among the National Inpatient Sample patients aged >=18 years and hospitalized for acute myocardial infarction during the 2012-2014 period, we examined the association between diabetes and the incidence and outcomes of cardiogenic shock complicating acute myocardial infarction, using multivariable logistic and linear regression models. RESULTS: Of 1,332,530 hospitalizations for acute myocardial infarction, 72,765 (5.5%) were complicated by cardiogenic shock. In acute myocardial infarction patients, cardiogenic shock incidence was higher among those with vs without diabetes (5.8% vs 5.2%; adjusted odds ratio [aOR] 1.14; 95% confidence interval [CI], 1.11-1.19; P < .001), with 42.8% (n = 31,135) of patients with acute myocardial infarction and cardiogenic shock having diabetes. Diabetic patients were less likely to undergo revascularization (percutaneous coronary intervention or coronary artery bypass grafting) (67.1% vs 68.7%; aOR 0.88; 95% CI, 0.80-0.96; P = .003). Diabetes was associated with higher in-hospital mortality in patients with acute myocardial infarction and cardiogenic shock (37.9% vs 36.8%; aOR 1.18; 95% CI, 1.09-1.28; P < .001). Among survivors, patients with diabetes had a longer hospital stay (mean +/- SEM: 11.6 +/- 0.16 vs 10.9 +/- 0.16 days; adjusted estimate 1.12; 95% CI, 1.06-1.18; P < .001) and were more likely to be discharged to a skilled nursing home or with home health care (56.0% vs 50.5%; aOR 1.19; 95% CI, 1.07-1.33; P = .001). CONCLUSIONS: In a large cohort of acute myocardial infarction patients, preexisting diabetes was associated with an increased risk of cardiogenic shock and worse outcomes in those with cardiogenic shock.

AB - Dimeric cytochromes bc are central components of photosynthetic and respiratory electron transport chains. In their catalytic core, four hemes b connect four quinone (Q) binding sites. Two of these sites, Qi sites, reduce quinone to quinol (QH2) in a step-wise reaction, involving a stable semiquinone intermediate (SQi). However, the interaction of the SQi with the adjacent hemes remains largely unexplored. Here, by revealing the existence of two populations of SQi differing in paramagnetic relaxation, we present a new mechanistic insight into this interaction. Benefiting from a clear separation of these SQi species in mutants with a changed redox midpoint potential of hemes b, we identified that the fast relaxing SQi (SQiF) corresponds to the form magnetically coupled with the oxidized heme bH (the heme b adjacent to the Qi site), while the slow-relaxing SQi (SQiS) reflects the form present alongside the reduced (and diamagnetic) heme bH. This so far unreported SQiF calls for a reinvestigation of the thermodynamic properties of SQi and the Qi site. The existence of SQiF in the native enzyme reveals a possibility of an extended electron equilibration within the dimer, involving all four hemes b and both Qi sites. This substantiates the predicted earlier electron transfer acting to sweep the b-chain of reduced hemes b to diminish generation of reactive oxygen species by cytochrome bc1. In analogy to the Qi site, we anticipate that the quinone binding sites in other enzymes may contain yet undetected semiquinones which interact magnetically with oxidized hemes upon progress of catalytic reactions.

AB - Paragonimiasis is a subacute to chronic inflammatory granulomatous lung disease caused by the genus Paragonimus. In Latin America Paragonimus mexicanus Miyazaki & Ishii, 1968 is the only confirmed species to cause human infections. Paragonimus caliensis Little, 1968 is an uncommon species often regarded as a synonym of P. mexicanus. Recently, the study of two types of Paragonimus metacercariae from Costa Rica has provided new molecular and morphological evidence that P. caliensis is a separate species from P. mexicanus. In the present study, molecular, morphological and phylogenetic tools have been used to characterize two populations of Paragonimus located at west of Medellin, Antioquia and at Pichinde, Valle del Cauca (type locality of P. caliensis), Colombia. Adults and metacercariae obtained from Medellin, and metacercariae from Pichinde were analyzed. For morphological observations we used light microscopy and scanning electron microscopy (SEM). Morphology of metacercariae and adults matched with the holotype of P. caliensis. The number and arrangement of sensory papillae in the acetabulum region differs from the morphotypes reported for P. caliensis in Costa Rica. Two morphotypes in branching patterns of ovary and two morphotypes in branching patterns of testes were identified. The main morphological differences between P. caliensis and P. mexicanus corresponded to the size of gonads and their relative positions in the body, and the occasional presence of a cyst wall in P. caliensis metacercariae. The molecular and phylogenetic analyses (using nuclear ribosomal ITS2 and partial cytochrome c oxidase subunit 1 CO1 sequences) confirmed that P. caliensis from the type locality is the same species from Medellin and Costa Rica. Furthermore, these analyses also suggest genetic as well as geographical separation of P. caliensis populations between Colombia and Costa Rica. Currently, P. mexicanus and P. caliensis are sympatric in the Colombian Pacific bioregion, and specific diagnosis based on their egg size is not possible. Therefore, it is necessary to determine the biogeographic distribution ranges of both species and to implement molecular techniques to establish the role of P. caliensis in human paragonimiasis in Colombia.

AB - BACKGROUND: Vitamin D is a lipid-soluble molecule that plays key physiological roles in the metabolism of calcium, phosphate and magnesium. Recent studies show that deficiency in vitamin D is linked to cardiovascular diseases, autoimmune diseases and cancer. As a result, regular monitoring of 25-OH vitamin D (the main circulating form of vitamin D) is becoming essential. Current 25-OH vitamin D testing methodologies are cumbersome (too many reagents, long incubation times, phase separation) and are not compatible with general clinical chemistry platforms. Here, we report on a novel method to detect 25-OH vitamin D that is fast (results in 10 min or less), simple (two reagents) and compatible with virtually all general clinical chemistry analyzers. METHODS: An immunoturbidimetric assay for 25-OH vitamin D (the Diazyme EZ Vitamin D Assay) has been developed using nanoparticles and vitamin D-specific antibodies. The performance of the assay kit, which consists of two reagents and five calibrators, was tested on the Beckman AU680 analyzer (AU680). RESULTS: The new assay was precise, sensitive (LOD = 7.2 nmol/L), linear (up to 390.1 nmol/L) and correlated strongly (R2 > 0.95) with major commercial 25-OH vitamin D assays. Additionally, the assay was found to be the fastest to date, with the first results obtained within 10 min. Throughput on the AU680 was estimated at over 300 tests per hour. CONCLUSIONS: The newly developed 25-OH vitamin D assay is fast, precise and accurate. It can be run on most general chemistry analyzers. This assay aims at providing vitamin D-testing capabilities to all clinical chemistry laboratories. PMID- 29596794 TI - Selection of Submucosal Steroids to Minimize Postsurgical Pain. PMID- 29596791 TI - Optimization and 13CH3 methionine labeling of a signaling competent neurotensin receptor 1 variant for NMR studies. AB - Neurotensin is a 13-residue peptide that acts as a neuromodulator of classical neurotransmitters such as dopamine and glutamate in the mammalian central nervous system, mainly by activating the G protein-coupled receptor (GPCR), neurotensin receptor 1 (NTS1). Agonist binding to GPCRs shifts the conformational equilibrium of the transmembrane helices towards distinct, thermodynamically favorable conformations that favor effector protein interactions and promotes cell signaling. The introduction of site specific labels for NMR spectroscopy has proven useful for investigating this dynamic process, but the low expression levels and poor stability of GPCRs is a hindrance to solution NMR experiments. Several thermostabilized mutants of NTS1 have been engineered to circumvent this, with the crystal structures of four of these published. The conformational dynamics of NTS1 however, has not been thoroughly investigated with NMR. It is generally accepted that stabilized GPCRs exhibit attenuated signaling, thus we thoroughly characterized the signaling characteristics of several thermostabilized NTS1 variants to identify an optimal variant for protein NMR studies. A variant termed enNTS1 exhibited the best combination of signaling capability and stability upon solubilization with detergents. enNTS1 was subsequently labeled with 13CH3-methionine in E. coli and purified to homogeneity in the absence of bound ligands. Using solution NMR spectroscopy we observed several well dispersed 13CH3-methionine resonances, many of which exhibited chemical shift changes upon the addition of the high affinity agonist peptide, NT8-13. Thus, enNTS1 represents a novel tool for investigating ligand induced conformational changes in NTS1 to gain insights into the molecular mechanisms underlying neurotensin signaling. PMID- 29596793 TI - Correlation of oxidative stress in patients with HBV-induced liver disease with HBV genotypes and drug resistance mutations. AB - OBJECTIVE: This study aims to explore the correlation of oxidative stress (OxS) in patients with chronic hepatitis B (CHB) and the disease severity with HBV genotypes and drug resistance mutations. METHODS: A total of 296 patients with CHB were enrolled into the study. PCR-reverse dot-blot hybridization was used to detect the HBV genotypes (B, C, and D) and the drug resistance-causing HBV mutant genes. In addition, the total oxidative stress (TOS) and total antioxidant status (TAS) were determined, and oxidative stress index (OSI) was calculated and compared. RESULTS: Serum levels of TOS and OSI, the B/C ratio, and drug resistance mutation rate were increased along with the elevated disease severity degree (CHB T variant has been associated with lactase persistence whereas other persistence variants, e.g. -13907C > G and -13915 T > G, have been identified in Africa and the Middle East. The aim of the present study was to compare a previously developed high resolution melting assay (HRM) with a novel method based on loop-mediated isothermal amplification and melting curve analysis (LAMP-MC) with both whole blood and DNA as input material. METHODS: To evaluate the LAMP-MC method, we used 100 whole blood samples and 93 DNA samples in a two tiered study. First, we studied the ability of the LAMP-MC method to produce specific melting curves for several variants of the LCT enhancer region. Next, we performed a blinded comparison between the LAMP-MC method and our existing HRM method with clinical samples of unknown genotype. RESULTS: The LAMP-MC method produced specific melting curves for the variants at position -13909, -13910, 13913 whereas the -13907C > G and -13915 T > G variants produced indistinguishable melting profiles. CONCLUSION: The LAMP-MC assay is a simple method for lactase persistence genotyping and compares well with our existing HRM method. PMID- 29596782 TI - Scalable Open Science Approach for Mutation Calling of Tumor Exomes Using Multiple Genomic Pipelines. AB - The Cancer Genome Atlas (TCGA) cancer genomics dataset includes over 10,000 tumor normal exome pairs across 33 different cancer types, in total >400 TB of raw data files requiring analysis. Here we describe the Multi-Center Mutation Calling in Multiple Cancers project, our effort to generate a comprehensive encyclopedia of somatic mutation calls for the TCGA data to enable robust cross-tumor-type analyses. Our approach accounts for variance and batch effects introduced by the rapid advancement of DNA extraction, hybridization-capture, sequencing, and analysis methods over time. We present best practices for applying an ensemble of seven mutation-calling algorithms with scoring and artifact filtering. The dataset created by this analysis includes 3.5 million somatic variants and forms the basis for PanCan Atlas papers. The results have been made available to the research community along with the methods used to generate them. This project is the result of collaboration from a number of institutes and demonstrates how team science drives extremely large genomics projects. PMID- 29596816 TI - Comparison of serum serotonin and serum 5-HIAA LC-MS/MS assays in the diagnosis of serotonin producing neuroendocrine neoplasms: A pilot study. AB - BACKGROUND: Serotonin (5-hydroxytyramine) is a mediator of gastrointestinal smooth muscle contraction, and is secreted by neuroendocrine neoplasms (NENs). We developed a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for serum serotonin to be used in NEN diagnostics and follow-up. METHODS: We used serum samples from healthy volunteers (n = 31) and patients suspected or monitored for NEN (n = 98). Serotonin-D4 internal standard was added to samples before solid phase extraction (SPE) and quantification by LC-MS/MS. The effects of sample handling and preparation on serotonin stability were studied. Finally, we established a provisional reference range for serum serotonin and compared our assay with serum 5-hydroxyindoleacetic acid (5-HIAA) for detection of NENs. RESULTS: Our assay is sensitive and has a wide linear range (10-10,000 nmol/l). Serum serotonin is stable for 7 days at room temperature and for 3 months at -20 degrees C. Sampling temperature is not critical. Normal range for serum serotonin was 270-1490 nmol/l. We found that serum serotonin and 5-HIAA performed equally well as diagnostic tests for NENs. CONCLUSIONS: Our LC-MS/MS assay for serum serotonin is well suited for clinical research and patient diagnostics. Our results confirm that it can complement 5-HIAA in diagnosis of NENs. PMID- 29596817 TI - Isolated Hemorrhagic Pericardial Effusion After Foreign Body Ingestion. AB - Foreign body ingestion is one of the many potential causes of esophageal perforation. In this case report we describe a man who presented with chest pain and was found to have an isolated hemorrhagic pericardial effusion secondary to occult ingestion and pericardial migration of a metallic foreign body. Surgical management was successful, and the patient has recovered well. PMID- 29596815 TI - Therapeutic drug monitoring of piperacillin and tazobactam by RP-HPLC of residual blood specimens. AB - BACKGROUND: Sepsis is a common diagnosis in critical care with inpatient mortality rates up to 50%. Sepsis care is organized around source control, antibiotics, and supportive care. Drug disposition is deranged by changes in volume of distribution and regional blood flow, as well as multiple organ failure. Thus, assuring that each patient with sepsis attains pharmacokinetic targets is challenging. There is currently no commercially available FDA-approved assay to measure piperacillin-tazobactam, very commonly used as a beta lactam/beta-lactamase inhibitor combination antibiotic in the intensive care unit (ICU). METHODS: Samples were prepared by ultrafiltration of plasma collected in lithium heparin Vacutainers. Separation was achieved by gradient elution on a C 18 column followed by UV detection at 214 nm. The method is validated in residual blood samples allowing investigators to exploit a waste product to develop insight into beta-lactam pharmacokinetics in the ICU. RESULTS: Accuracy and precision were within the 25% CLIA error standard for other antibiotic assays. Free piperacillin concentrations were also in good agreement with total piperacillin concentrations measured in the same plasma by an assay in clinical use outside the United States. CONCLUSION: We describe a method for measuring piperacillin and tazobactam that meets clinical validation standards. Quick turnaround time and excellent accuracy on a low-cost platform make this method more than adequate for use as a routine therapeutic drug monitoring tool. PMID- 29596818 TI - Clinical Outcomes of Root Reimplantation and Bentall Procedure: Propensity Score Matching Analysis. AB - BACKGROUND: This study aimed to evaluate the clinical outcomes of aortic root replacement (ARR) surgery: Root reimplantation as valve-sparing root replacement (VSR) and the Bentall procedure. METHODS: We retrospectively reviewed 216 patients who underwent ARR between 1995 and 2013 at Samsung Medical Center. Patients were divided into two groups, depending on the procedure they underwent: Bentall (n = 134) or VSR (n = 82). The mean follow-up duration was 100.9 +/- 56.4 months. RESULTS: There were 2 early deaths in the Bentall group and none in the VSR group (p = 0.53). Early morbidities were not different between the groups. Overall mortality was significantly lower in the VSR group (HR = 0.12, p = 0.04). Despite the higher reoperation rate in the VSR group (p = 0.03), major adverse valve-related events (MAVRE) did not differ between the groups (p = 0.28). Bleeding events were significantly higher in the Bentall group during follow-up (10 in Bentall group, 0 in VSR group, p = 0.04). There were 6 thromboembolic events only in the Bentall group (p = 0.11). We performed a propensity score matching analysis comparing the groups (134 Bentall versus 43 VSR). Matched analysis gave similar results, namely, HR = 0.17, p = 0.10 for overall mortality and HR = 1.01, p = 0.99 for MAVRE. CONCLUSIONS: Although there was marginal significance in the propensity matched analysis, it is plausible to anticipate a survival benefit with VSR during long-term follow-up. Despite a higher reoperation for aortic valves, VSR can be a viable option in patients who decline life-long anticoagulation, especially the young or the patients in whom anticoagulation is contraindicated. PMID- 29596820 TI - Patterns of Practice in Mediastinal Lymph Node Staging for Non-Small Cell Lung Cancer in Canada. AB - BACKGROUND: Assessment of mediastinal lymph nodes is integral in staging patients with non-small cell lung cancer (NSCLC). This study delineated the lymph node staging practices of Canadian thoracic surgeons in patients with potentially resectable NSCLC. METHODS: A questionnaire was distributed to Canadian Association of Thoracic Surgeons members (n = 86). Items addressed the use of imaging, thresholds/methods for preoperative invasive staging, and intraoperative node staging. Comparison was made against Canadian, American, and European guidelines. RESULTS: Forty-seven surgeons (55%) responded. Although most stated they derived practices from published guidelines, a significant proportion did not reflect those recommendations. Most respondents ordered a positron emission tomography scan for every patient (87.2%), and the same proportion (87.2%) performed invasive staging selectively, with a wide range of indications. The most common thresholds were suspicious nodes on imaging (80.5%), tumor within the central third of the lung (67.5%), and tumor exceeding 3 cm (34.2%). Endobronchial ultrasound, alone or with endoscopic ultrasound, was selected as the initial staging procedure of choice by 47.9%, and 43.5% selected mediastinoscopy first. Of surgeons selecting mediastinoscopy, 61.9% reported some barriers to performing endobronchial ultrasound. There was variability, between surgeons and between lobes, in which nodes respondents harvested intraoperatively for given lobectomies. A sizeable minority (13%) did not routinely harvest lymph nodes intraoperatively. CONCLUSIONS: Determining the appropriate treatment and prognosis of NSCLC patients relies on proper staging. Significant variability exists in node staging practices in Canada as well as divergence from guidelines. This may result in understaging or overstaging patients and inappropriate care. PMID- 29596819 TI - Dehiscence of Bronchial Anastomosis After Lung Transplantation: A Successful Unconventional Treatment. AB - Anastomotic airway complications, including the dehiscence of the bronchial anastomosis, are a severe cause of morbidity after lung transplantation. We present a case of dehiscence treated by placing an uncovered metal stent into the main bronchus. We usually use this procedure for bronchial stenosis, but in this case, the stent favored the growth of granulation tissue and so the closure of the dehiscence. This procedure was minimally invasive and may be an alternative to an open repair, without precluding open repair in case of failure. PMID- 29596783 TI - Pan-cancer Alterations of the MYC Oncogene and Its Proximal Network across the Cancer Genome Atlas. AB - Although the MYC oncogene has been implicated in cancer, a systematic assessment of alterations of MYC, related transcription factors, and co-regulatory proteins, forming the proximal MYC network (PMN), across human cancers is lacking. Using computational approaches, we define genomic and proteomic features associated with MYC and the PMN across the 33 cancers of The Cancer Genome Atlas. Pan cancer, 28% of all samples had at least one of the MYC paralogs amplified. In contrast, the MYC antagonists MGA and MNT were the most frequently mutated or deleted members, proposing a role as tumor suppressors. MYC alterations were mutually exclusive with PIK3CA, PTEN, APC, or BRAF alterations, suggesting that MYC is a distinct oncogenic driver. Expression analysis revealed MYC-associated pathways in tumor subtypes, such as immune response and growth factor signaling; chromatin, translation, and DNA replication/repair were conserved pan-cancer. This analysis reveals insights into MYC biology and is a reference for biomarkers and therapeutics for cancers with alterations of MYC or the PMN. PMID- 29596821 TI - Intraoperative Device Closure of Isolated Ventricular Septal Defects: Experience on 1,090 Cases. AB - BACKGROUND: This study summarizes the clinical experience and 8-year follow-up results of the intraoperative device closure of ventricular septal defects (VSD). METHODS: From January 2009 to June 2017, 1,090 patients with isolated VSD were enrolled at our institute to participate in the study. The procedure involved a small lower sternal incision that was performed after full evaluation of VSD by transesophageal/transthoracic echocardiographic (TEE/TTE) guidance and the deployment of a domestically made occluder to close the VSD periventricularly and off cardiopulmonary bypass. Follow-up was in the first 3 months and then every 1 to 2 years with TTE, electrocardiography, and upon symptoms. RESULTS: In all, 1,033 patients were occluded successfully under this approach, and the remaining patients were converted to surgical repair. The size of the occluder deployed ranged from 6 to 14 mm and included 825 symmetric devices and 208 asymmetric devices. A total of 25 patients developed severe arrhythmias, including 11 cases of complete atrioventricular block and 14 cases of Mobitz type II atrioventricular block, during and after the procedure. CONCLUSIONS: Minimally invasive transthoracic device closure of VSD with an asymmetric or symmetric domestically made device on a beating heart is a safe and feasible alternative to conventional surgical repair. More experience in multicenter and long-term follow up is necessary to assess the actual feasibility and safety of this procedure. PMID- 29596822 TI - Impact of Regional Collaboration on Quality Improvement and Associated Cost Savings in Coronary Artery Bypass Grafting. AB - BACKGROUND: A statewide database identified prolonged ventilation (PV) and acute renal failure (RF) as the biggest cost drivers after isolated coronary artery bypass grafting. Reducing these complications through regional collaboration should improve outcomes and lower health care costs. METHODS: A total of 27,978 patients who underwent isolated coronary artery bypass grafting were divided into pre- and post-quality improvement initiative groups (early era: 2008 to 2011, n = 15,176; later era: 2012 to 2015, n = 12,802). Focused learning sessions on PV and postoperative RF were undertaken in the earlier era. Incidence of death, PV, and RF in the two groups was analyzed using one-way analysis of variance and Fisher exact tests. RESULTS: The Society of Thoracic Surgeons (STS) predicted risk of mortality and predicted risk of mortality/morbidity were significantly higher in the later era (p < 0.01), as were STS predicted PV (10.1% vs 11.3%) and RF (3.4% vs 3.8%). Despite these increased risks, STS observed-to-expected ratios for mortality and mortality/morbidity fell. Observed rates for PV (10.5% vs 8.8%, p < 0.01) and RF (3.6% vs 2.3%, p < 0.01) were associated with STS observed-to expected ratios of PV (1.04 vs 0.78) and RF (1.03 vs 0.60). Adjusting for case volume in the two eras, 271 cases of PV and 170 of RF were avoided, with estimated cost savings of $10,212,637 and $8,519,630, respectively. CONCLUSIONS: A regional collaboration using a statewide STS and an all-payor database with focused quality improvement is a powerful tool for change. Despite rising risks for mortality and morbidity, outcomes for PV and RF improved and produced significant cost savings. Applying these efforts nationally can enormously affect patient care and health care costs. PMID- 29596825 TI - Alterations of circular RNAs in hyperglycemic human endothelial cells. AB - Circular RNA (circRNA), a family of RNA generated by RNA circularization, is ubiquitously expressed in tissues and possesses increasingly important biological functions. Hyperglycemia-induced endothelial dysfunction is an initiating event in the pathogenesis of diabetes-associated cardiovascular complications. How high glucose may affect circRNAs is unknown. To address this issue, human endothelial cells were exposed to high glucose treatment and the changes of circRNAs were measured by RNA sequencing. A total 3686 circRNAs, including 1040 previously unrecorded circRNAs, were detected; and 95 different expression (DE) circRNAs were observed. The host genes of these DE circRNAs were further studied by function enrichment analyses. These analyses revealed genes of phosphoproteins, transferases, and zine finger proteins. Since circRNAs can function as a microRNA (miRNA) sponge, circRNAs-miRNAs interaction networks were explored by bioinformatics. These analyses identified a number of miRNAs, which might interact with DE circRNAs and play roles in the actions of high glucose on endothelial cells. These results demonstrate that high glucose exposure profoundly changes circRNA expression in endothelial cells. Altered circRNA expression may contribute to the effects of high glucose on endothelial function in diabetes. PMID- 29596823 TI - CXCL8 is associated with the recurrence of patients with acute myeloid leukemia and cell proliferation in leukemia cell lines. AB - Acute myeloid leukemia (AML) blasts release a wide range of chemokines in which CXCL8 has recently been recognized to be important for tumor progression. To find out the function of CXCL8 in AML, we compared blood serum of AML patients and healthy donors and found that the average level of CXCL8 was higher in AML patients. Among patients, higher expression of CXCL8 was also a positive recurrence indicator which illustrated the critical role of CXCL8 in AML. Knocking down of CXCL8 in leukemic cell lines led to significant reduction of proliferation via inducing G0/G1 cell cycle arrest and apoptosis, which was accompanied by the inactivation of ERK1/2. Furthermore, inhibition of ERK1/2 by specific chemical inhibitors reconstructed the CXCL8 knocking down phenomenon. Overall, we demonstrated that expression level of CXCL8 had a positive relationship with recurrence probability in AML. And CXCL8 was strongly implicated in AML cells growth by activating the ERK1/2 signal pathway. PMID- 29596826 TI - HDA9 interacts with the promoters of SOC1 and AGL24 involved in flowering time control in Brassica juncea. AB - HDA9 (a RPD3-like histone deacetylase) belongs to the histone deacetylase family which is involved in flowering time control through repression of AGL19 and FT, but it is still elusive that whether and how HDA9 directly interacts with flowering signal integrators of SOC1 and AGL24 in Brassica juncea. In this study, BjuHDA9 (a homologous HDA9) was cloned from B. juncea and ubiquitously expressed in root, stem, cauline leaf, flower bud and opening flower. BjuHDA9 was highly induced by short-day photoperiod. Yeast two-hybrid and pull-down assays demonstrated that BjuHDA9 could not interact with BjuSOC1 and BjuAGL24 proteins. Whereas, BjuHDA9 directly interacted with promoters of BjuSOC1 and BjuAGL24 via yeast one-hybrid and Dual-Glo(r) Luciferase assays. It suggested that the histone deacetylase BjuHDA9 was probably involved in flowering time control by binding to promoter regions of BjuSOC1 and BjuAGL24. This study will provide valuable information for elucidating the molecular mechanism of BjuHDA9 in regulating flowering time. PMID- 29596824 TI - Crystal structure of E. coli ZinT with one zinc-binding mode and complexed with citrate. AB - The ZnuABC ATP-binding cassette transporter found in gram-negative bacteria has been implicated in ensuring adequate zinc import into Zn(II)-poor environments. ZinT is an essential component of ZnuABC and contributes to metal transport by transferring metals to ZnuA, which delivers them to ZnuB in periplasmic zinc recruitment. Although several structures of E. coli ZinT have been reported, its zinc-binding sites and oligomeric state have not been clearly identified. Here, we report the crystal structure of E. coli ZinT at 1.76 A resolution. This structure contains one zinc ion in its calycin-like domain, and this ion is coordinated by three highly conserved histidine residues (His167, His176 and His178). Moreover, three oxygen atoms (O1, O6 and O7) from the citrate molecule interact with zinc, giving the zinc ion stable octahedral coordination. Our EcZinT structure shows the fewest zinc ions bound of all reported EcZinT structures. Crystallographic packing and size exclusion chromatography suggest that EcZinT prefers to form monomers in solution. Our results provide insights into the molecular function of ZinT. PMID- 29596827 TI - Structural and biochemical characterization of the type-II LOG protein from Streptomyces coelicolor A3. AB - Streptomyces coelicolor A3 contains Sc5140, a gene coding for poorly understood bacterial LOG-like protein. In this study, we determined the crystal structure of Sc5140 and found it resembles the overall structure of other type-II LOGs. In addition, Sc5140 exhibited phosphoribohydrolase activity against adenosine monophosphate (AMP), indicating that it had the same function as known type-II LOGs. Based on these results, we designated Sc5140 as ScLOGII. We performed docking calculations of AMP into the ScLOGII structure, which suggested the mode of binding for type-II LOG with their AMP substrate. The ScLOGII structure uniquely exhibited a long tail-like structure at the N-terminus that was involved in hexamerization of the protein; the disordered N-terminal region (DNR). Truncation of DNR in ScLOGII negatively affected both the phosphoribohydrolase activity and the oligomerization of the protein, suggesting that this region functioned in enzyme stabilization. However, results from truncation experiments using ScLOGII and CgLOGII, a type-II LOG homologue from Corynebacterium glutamicum, were quite different, leaving uncertainty regarding the general functions of DNR in type-II LOGs. Overall, the current structural work may help in understand the significance of type-II LOG protein at the molecular level. PMID- 29596828 TI - NFATc3 deficiency protects against high fat diet (HFD)-induced hypothalamus inflammation and apoptosis via p38 and JNK suppression. AB - Hypothalamic inflammation and apoptosis cause neural injury, playing an important role in metabolic syndrome development. Nuclear Factors of Activated T cells (NFATc3) show many physiological and pathological effects. However, the function of NFATc3 in high fat diet (HFD)-induced hypothalamus injury remains unknown. The wild type (WT) and NFATc3-knockout (KO) mice were subjected to HFD feeding for 16 weeks to examine NFATc3 function in vivo. Astrocytes isolated from WT or KO mice were cultured and exposed to fructose (Fru) in vitro. The liver damage, hypothalamus injury, pro-inflammatory markers, NF-kappaB (p65), Caspase-3 and mitogen-activated protein kinases (MAPKs) pathways were evaluated. NFATc3 was significantly up-regulated in hypothalamus from mice challenged with HFD, and in astrocytes incubated with Fru. Both in vivo and in vitro studies indicated that NFATc3-deletion attenuated metabolism syndrome, reduced inflammatory regulators expression, inactivated NF-kappaB (p65), Caspase-3 and p38/JNK signaling pathway. Of note, we identified that promoting p38 or JNK activation could rescue inflammatory response and apoptosis in NFATc3-KO astrocytes stimulated by Fru. Together, these findings revealed an important role of NFATc3 NFATc3 for HFD induced metabolic syndrome and particularly hypothalamus injury, and understanding of the regulatory molecular mechanism might provide new and effective therapeutic strategies for prevention and treatment of hypothalamic damage associated with dietary obesity-associated neuroinflammation and apoptosis. PMID- 29596829 TI - Influence of acute promyelocytic leukemia therapeutic drugs on nuclear pore complex density and integrity. AB - During cell division, a large number of nuclear proteins are released into the cytoplasm due to nuclear envelope breakdown. Timely nuclear import of these proteins following exit from mitosis is critical for establishment of the G1 nuclear environment. Dysregulation of post-mitotic nuclear import may affect the fate of newly divided stem or progenitor cells and may lead to cancer. Acute promyelocytic leukemia (APL) is a malignant disorder that involves a defect in blood cell differentiation at the promyelocytic stage. Recent studies suggest that pharmacological concentrations of the APL therapeutic drugs, all-trans retinoic acid (ATRA) and arsenic trioxide (ATO), affect post-mitotic nuclear import of the APL-associated oncoprotein PML/RARA. In the present study, we have investigated the possibility that ATRA and ATO affect post-mitotic nuclear import through interference with components of the nuclear import machinery. We observe reduced density and impaired integrity of nuclear pore complexes after ATRA and/or ATO exposure. Using a post-mitotic nuclear import assay, we demonstrate distinct import kinetics among different nuclear import pathways while nuclear import rates were similar in the presence or absence of APL therapeutic drugs.

AB - Liposome-encapsulated clodronate (LEC) is a specific depletor of macrophages. Our study characterized the LEC depletory effects, given intrathecally, on spinal microglia and assessed its effects on initiation and maintenance of neuropathic pain. Measured by using the MTT assay, LEC treatment specifically inhibited cell viability of cultured primary microglia, but not astrocytes or neurons, from neonatal rats, with an IC50 of 43 MUg/mL. In spinal nerve ligation-induced neuropathic rats, pretreatment (1 day but not 5 days earlier) with intrathecal LEC specifically depleted microglia (but not astrocytes or neurons) in both contralateral and ipsilateral dorsal horns by the same degree (63% vs. 71%). Intrathecal injection of LEC reversibly blocked the antinociceptive effects of the GLP-1 receptor agonist exenatide and dynorphin A stimulator bulleyaconitine, which have been claimed to be mediated by spinal microglia, whereas it failed to alter morphine- or the glycine receptor agonist gelsemine-induced mechanical antiallodynia which was mediated via the neuronal mechanisms. Furthermore, intrathecal LEC injection significantly attenuated initial (one day after nerve injury) but not existing (2 weeks after nerve injury) mechanical allodynia. Our study demonstrated that LEC, given intrathecally, is a specific spinal microglial inhibitor and significantly reduces initiation but not maintenance of neuropathic pain, highlighting an opposite role of spinal microglia in different stages of neuropathic pain.

AB - Breast cancer is a tremendous threat to humans in many countries, and thus we need to find safe and effective drugs for treatment. Ginsenoside Rh4 has been reported to be present in processed ginseng. However, few studies have focused on its anti-tumor activity. In this study, we investigated the inhibitory effects of ginsenoside Rh4 on MCF-7 breast cancer cells and the pathways that promote apoptosis in vitro. To study the effect of ginsenoside Rh4 in vivo, xenograft models were randomly divided into 3 groups (the control group, 10 mg/kg/d Rh4, 20 mg/kg/d Rh4, n = 10 per group), the ginsenoside Rh4 injection method was i.p. The results showed that ginsenoside Rh4 effectively inhibited proliferation, arrested the cell cycle in S phase and induced apoptosis in MCF-7 cells by flow cytometry. Morphological changes caused by ginsenoside Rh4-induced apoptosis were also observed by Hoechst 33342 staining. Western-blot analyses indicated that the apoptosis-inducing effects of ginsenoside Rh4 were associated with the external pathway by decreasing Bcl-2, increasing Bax, and activating caspase-8, -3 and PARP. Moreover, ginsenoside Rh4 significantly inhibited the growth of MCF-7 tumor cells in vivo. These results suggested that ginsenoside Rh4 could be a potentially effective anti-tumor drug for breast cancer.

AB - BACKGROUND: The Amur tiger is one of the most endangered species in the world, and the healthy population of captive Amur tigers assists the recovery of the wild population. Gut microbes have been shown to be important for human disease and health, but little research exists regarding the microbiome of Amur tigers in captivity. METHODS: In this study, we used an integrated approach of 16S rRNA gene sequencing combined with ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS)-based metabolomics to analyze the effects of Fenbendazole and Ivermectin Tablets on the gut microbiota and fecal metabolic phenotype of the Amur tiger. RESULTS: The relative abundances of the bacterial genera Collinsella, Clostridium XI and Megamonas were decreased, whereas those of Escherichia and Clostridium sensu stricto were increased in experimental Amur tigers compared with those in normal controls. Meanwhile, distinct changes in the fecal metabolic phenotype of the experimental Amur tigers were also found, including lower levels of acrylic acid, acetoacetate and catechol and higher amounts of 5,6 dihydrouracil, adenine hydrochloride hydrate and galactitol. Moreover, the differentially abundant gut microbes were substantially associated with the altered fecal metabolites, especially the bacteria in the Firmicutes and Actinomycetes, which were involved in the metabolism of 5,6-dihydrouracil, 6 phospho-d-gluconate and 1-methylnicotinamide. CONCLUSION: Our results indicate for the first time that Fenbendazole and Ivermectin Tablets not only disturb the gut microbiota at the abundance level but also alter the metabolic homeostasis of the Amur tiger. PMID- 29596833 TI - A novel TBX1 missense mutation in patients with syndromic congenital heart defects. AB - Congenital heart defects represent a characteristic part of several genetic syndromes associated with chromosomal abnormalities such as 22q11.2 deletion syndrome; many genes located in this locus, mainly TBX1, are candidate genes for congenital heart defects. In our cohort of 27 subjects with congenital heart defect, both karyotype analysis and Fluorescence in situ hybridization (FISH) were performed. The TBX1 gene was sequenced in patients lacking chromosomal abnormalities. FISH analysis showed a de novo 22q11.2 deletion in two patients. The screening of TBX1 coding sequence identified a novel missense mutation c.569C > A (p.P190Q) in six unrelated patients and detected two associated known single nucleotide polymorphisms; the c.664C > T (rs2301558) in three patients and the c.420T > C (p.Phe140 Phe) (rs41298814) in one patient. Bioinformatic tools show that the novel missense mutation c.569C > A could modify the function and the stability of the TBX1 protein. The c.569C > A mutation was not found in 50 healthy controls. Ours results suggest a deleterious role of the c.569C > A mutation and strengthen the hypothesis that this mutation might be responsible for the same phenotype spectrum as the 22q11.2 deletion syndrome. PMID- 29596834 TI - AZD5153, a novel BRD4 inhibitor, suppresses human thyroid carcinoma cell growth in vitro and in vivo. AB - The development of novel anti-papillary thyroid carcinoma agents is urgent. AZD5153 is a novel and specific Bromodomain-containing protein 4 (BRD4) inhibitor. Here, we show that AZD5153 dose-dependently inhibited survival, proliferation and cell cycle progression in TPC-1 cells and primary human thyroid carcinoma cells. Yet, it was non-cytotoxic to the primary thyroid epithelial cells. AZD5153 induced caspase-3/-9 and apoptosis activation in TPC-1 cells and primary cancer cells. Its cytotoxicity in TPC-1 cells was significantly attenuated with co-treatment of the caspase inhibitors. BRD4 expression was elevated in TPC-1 and primary human thyroid carcinoma cells, but was low in the thyroid epithelial cells. BRD4-regulated proteins, including c-Myc, Bcl-2 and cyclin D1, were significantly downregulated following AZD5153 treatment in TPC-1 and primary cancer cells. In vivo, oral administration of AZD5153 at well tolerated doses significantly inhibited TPC-1 xenograft growth in severe combined immunodeficient (SCID) mice. BRD4-dependent proteins, Myc, Bcl-2 and cyclin D1, were also downregulated in AZD5153-treated tumor tissues. Collectively, the results suggest that targeting BRD4 by AZD5153 inhibits human thyroid carcinoma cell growth in vitro and in vivo. PMID- 29596835 TI - TNF receptor associated factor 5 controls oncostatin M-mediated lung inflammation. AB - Oncostatin M (OSM) is involved in pathogenesis of several human inflammatory diseases including lung inflammation and fibrosis. Although accumulating evidence indicates that OSM mediates lung inflammation, the precise mechanism for OSM on lung inflammation still remains unclear. In this study, we found that OSM receptor was abundantly expressed on endothelial and stromal/fibroblast cells in the lung of mice. In vitro stimulation with OSM upregulated vascular cell adhesion molecule-1 (VCAM-1), which promotes eosinophil infiltration in the lung tissues, on freshly-isolated lung stromal/fibroblast cells from wild-type mice. However, these cells from TNF receptor associated factor 5 (TRAF5)-deficient mice failed to show the increase in VCAM-1 expression after OSM stimulation. Furthermore, Traf5-/- mice showed markedly attenuated lung inflammation in terms of eosinophil infiltration upon intranasal administration with OSM as compared to wild-type mice. These results indicate that TRAF5 is crucially involved in OSM mediated lung inflammation probably by inducing lung stromal/fibroblast cell activation. PMID- 29596836 TI - Radiation resistance of the lung adenocarcinoma is related to the AKT-Onzin POU5F1 axis. AB - Non-small cell lung carcinoma is the predominant type of lung cancer, and shows an easily developable tolerance to radiotherapy. Cancer stem cells are suggested to be involved in the resistance against therapies. Onzin might be accumulated during the process tumor overcoming the radiation stress. To address the relationship between Onzin, stemness and radiation resistance, we treated the lung cancer tumor bearing mice with radiaotherapy and observed the differences between radiation sensitive (RS) and resistant (RR) tumors. Immunohistochemistry and HE staining were used to observe Onzin and POU5F1 expression in tumor tissues. Quantitative realtime-PCR and Western blot were applied for Onzin and POU5F1 in tumors and cells. In-vitro cellular viability was assessed by CCK8 methods for tumor derived cells. The stably transfected A549 cell lines overexpressing Onzin were generated through lentivirus transfection. After radiotherapy, those RR adenocarcinoma tumors and cells derived from them showed an increased Onzin expression. Further, RR cells were found upregulated stemness, indicated by increased sphericity and proliferation, as well as POU5F1 expression. Next, we overexpressed Onzin in the A549 cells and found an elevated POU5F1 expression, increased proliferation, and enhanced sphericity. Moreover, this could be suppressed by the AKT inhibitor MK-2260. In vivo, the A549 cells overexpressing Onzin showed not only higher tumor formation capability and growth, but also a significant resistance to radiation. Taken together, RR tumors have upregulated Onzin and POU5F1 expression. Ectopic expression of Onzin promotes the POU5F1 expression as well as stemness functions, and confers adenocarcinomas the resistance to radiotherapy. PMID- 29596837 TI - Lipidomics biomarker studies: Errors, limitations, and the future. AB - Lipidomics is an ever-expanding subfield of metabolomics that surveys 3000 to 5000 individual lipids across more than 56 lipid subclasses, including lipid peroxidation products. Unfortunately, there exists a large number of publications with poor quality data obtained with unit mass resolution leading to many lipid misidentifications. This is further complicated by poor scientific oversight with regard to recognition of isobar issues, sample collection, and sample storage issues that inexplicably requires more detailed attention. Inadvertent or intentional obfuscation of relative quantification data represented as absolute quantification is a subtle but profound difference that may readers outside of the field may not realize, therefore, instigating disservice and unnecessary distrust in the scientific community. These issues need to be addressed aggressively as high quality data are essential for the translation of biomarker research to clinical practice. PMID- 29596839 TI - Hepatitis D diagnostics:Utilization and testing in the United States. AB - Hepatitis D virus (HDV) infection may accompany acute or chronic hepatitis B virus infection. While HDV infection in the United States is thought to be uncommon, there are limited data regarding frequency of testing, and prevalence of HDV antibody and HDV RNA. We evaluated the use of HDV antibody testing using electronic medical record (EMR) data. Among 1007 HBsAg positive patients, only 121 had been tested for HDV antibody. Testing was performed primarily by gastroenterologists/hepatologists and limited testing was performed in identifiable high risk groups including those with HBV/HIV coinfection. Overall, HDV antibody was detected in 3.3% (95% C.I. = 0.9%-8.2%) An HDV RNA assay was developed and validated and 138 HBV or HBV/HIV coinfected patients were tested. The prevalence of HDV among the HBV/HIV coinfected subjects was 2.2% (95% C.I. = 0-5.3%). In a U.S. Midwestern population of HBV infected patients, HDV testing is under-employed. Overall prevalence exceeds 2% whether testing by antibody or HDV RNA and more comprehensive HDV surveillance may be indicated. PMID- 29596838 TI - CSN5/Jab1 facilitates non-small cell lung cancer cell growth through stabilizing survivin. AB - CSN5/JAB1 is a critical subunit of the COP9 signalosome (CSN) and is essentially involved in diverse types of cancer, but little is known about the role of CSN5 in non-small cell lung cancer (NSCLC). In the current study, we found that CSN5 expression was higher in NSCLC tissues compared to the corresponding non-tumor tissues. High CSN5 expression level is closely correlated with tumor progression and poor survival in NSCLC patients. We also found that knockdown of CSN5 remarkably suppressed cell growth by inducing cell cycle arrest and apoptosis promotion in NSCLC cells. Mechanistic investigations revealed that CSN5 directly bound survivin and decreased its ubiquitination to enhance the protein stability of survivin. Additionally, our results confirmed that the tumor-promoting effects of CSN5 in NSCLC cells is at least partly through stabilization of survivin. Overall, our data suggested that CSN5 functions as an oncogenic gene in NSCLC, which could be a potential diagnostic and therapeutic target for NSCLC. PMID- 29596840 TI - Reduced Abd-B Hox function during kidney development results in lineage infidelity. AB - Hox genes can function as key drivers of segment identity, with Hox mutations in Drosophila often resulting in dramatic homeotic transformations. In addition, however, they can serve other essential functions. In mammals, the study of Hox gene roles in development is complicated by the presence of four Hox clusters with a total of 39 genes showing extensive functional overlap. In this study, in order to better understand shared core Hox functions, we examined kidney development in mice with frameshift mutations of multiple Abd-B type Hox genes. The resulting phenotypes included dramatically reduced branching morphogenesis of the ureteric bud, premature depletion of nephron progenitors and abnormal development of the stromal compartment. Most unexpected, however, we also observed a cellular level lineage infidelity in nephron segments. Scattered cells within the proximal tubules, for example, expressed genes normally expressed only in collecting ducts. Multiple combinations of inappropriate nephron segment specific marker expression were found. In some cases, cells within a tubule showed incorrect identity, while in other cases cells showed ambiguous character, with simultaneous expression of genes associated with more than one nephron segment. These results give evidence that Hox genes have an overlapping core function at the cellular level in driving and/or maintaining correct differentiation decisions. PMID- 29596842 TI - More than a syllable in fib-ROS-is: The role of ROS on the fibrotic extracellular matrix and on cellular contacts. AB - Fibrosis is characterized by excess deposition of extracellular matrix (ECM). However, the ECM changes during fibrosis not only quantitatively but also qualitatively. Thus, the composition is altered as the expression of various ECM proteins changes. Moreover, also posttranslational modifications, secretion, deposition and crosslinkage as well as the proteolytic degradation of ECM components run differently during fibrosis. As several of these processes involve redox reactions and some of them are even redox-regulated, reactive oxygen species (ROS) influence fibrotic diseases. Redox regulation of the ECM has not been studied intensively, although evidences exist that the alteration of the ECM, including the redox-relevant processes of its formation and degradation, may be of key importance not only as a cause but also as a consequence of fibrotic diseases. Myofibroblasts, which have differentiated from fibroblasts during fibrosis, produce most of the ECM components and in return obtain important environmental cues of the ECM, including their redox-dependent fibrotic alterations. Thus, myofibroblast differentiation and fibrotic changes of the ECM are interdependent processes and linked with each other via cell-matrix contacts, which are mediated by integrins and other cell adhesion molecules. These cell matrix contacts are also regulated by redox processes and by ROS. However, most of the redox-catalyzing enzymes are localized within cells. Little is known about redox-regulating enzymes, especially the ones that control the formation and cleavage of redox-sensitive disulfide bridges within the extracellular space. They are also important players in the redox-regulative crosstalk between ECM and cells during fibrosis. PMID- 29596843 TI - Viability assessment of primary growth oocytes following ovarian tissue vitrification of neotropical teleost pacu (Piaractus mesopotamicus). AB - Vitrification of ovarian tissue containing immature oocytes provides an important tool for protecting the endangered species and genetic diversity in aquatic species. Therefore, the main objective was to assess primary growth (PG) oocytes viability following ovarian tissue vitrification using histological analysis, two staining protocols (trypan blue or fluorescein diacetate combined with propidium iodide) and mitochondrial activity assay (MTT assay). In addition, oocyte histomorphometry was performed to evaluate the morphometric parameters after vitrification and the relationship with the occurrence of damage (nucleus and/or membrane) in PG oocytes. There was no significant difference among the vitrified oocytes using trypan blue dye or FDA + IP staining. Oocyte viability assessed using histological analysis showed that vitrification solution 2.0 M Me2SO + 2.5 M etilenoglycol +0.5 M sucrose (VS3; 66.43 +/- 4.68%) and 1.5 M methanol + 5.5 M Me2SO + 0.5 M sucrose (VS5; 74.14 +/- 3.71%) had the lowest viability rate. Similar results were observed in MTT assay where VS3 (1.63 +/- 0.12) and VS5 (1.58 +/- 0.09) had the lowest averages when compare with VS1 (2.39 +/- 0.14), VS2 (1.78 +/- 0.06) and VS4 (2.34 +/- 0.19) (P = 0.0002). In membrane damage evaluation by histology, there was no difference among vitrified oocytes and control. However, the highest percentages of nucleus damage were observed in treatments VS3 (26.00 +/- 5.55) and VS5 (26.00 +/- 5.55). Oocyte diameter did not change after vitrification; however, nucleus diameter was significantly higher in control group (49.03 +/- 1.07). Oocyte viability by histological analysis was positive-correlated to the occurrence of nucleus (r2 = 0.78) and membrane (r2 = 0.45) damage after vitrification/warming. The high viability of PG oocytes obtained after ovarian tissue vitrification of Piaractus mesopotamicus suggests that the protocol applied here might be used successfully in other teleost species for food production. PMID- 29596841 TI - miR-206 is required for changes in cell adhesion that drive muscle cell morphogenesis in Xenopus laevis. AB - MicroRNAs (miRNAs) are highly conserved small non-coding RNA molecules that post transcriptionally regulate gene expression in multicellular organisms. Within the set of muscle-specific miRNAs, miR-206 expression is largely restricted to skeletal muscle and is found exclusively within the bony fish lineage. Although many studies have implicated miR-206 in muscle maintenance and disease, its role in skeletal muscle development remains largely unknown. Here, we examine the role of miR-206 during Xenopus laevis somitogenesis. In Xenopus laevis, miR-206 expression coincides with the onset of somitogenesis. We show that both knockdown and over-expression of miR-206 result in abnormal somite formation affecting muscle cell rotation, attachment, and elongation. In particular, our data suggests that miR-206 regulates changes in cell adhesion that affect the ability of newly formed somites to adhere to the notochord as well as to the intersomitic boundaries. Additionally, we show that beta-dystroglycan and F-actin expression levels are significantly reduced, suggesting that knockdown of miR-206 levels affects cellular mechanics necessary for cell shape changes and attachments that are required for proper muscle formation. PMID- 29596844 TI - Molecular pathology of Multiple Sclerosis lesions reveals a heterogeneous expression pattern of genes involved in oligodendrogliogenesis. AB - Little is known about the decisive molecular factors that regulate lesion remyelination in Multiple Sclerosis. To identify such factors, we performed a differential gene expression analysis of normal appearing white matter (NAWM), active, remyelinating, and inactive demyelinated lesions. As expected, many genes involved in inflammatory processes were detected to be differentially regulated between these tissue types. Among them, we found an increased expression of members of the STAT6 pathway such as STAT6, IL4 and IL4R in active, remyelinated and inactive demyelinated lesions. This suggests that a protective, anti inflammatory reaction, as already reported to be present in MS NAWM, is further enhanced in lesion tissues. Focusing on genes influencing oligodendrogliogenesis, we found a decreased expression of NKX2-2 in active, remyelinated and inactive demyelinated lesions, whereas SOX10 was downregulated in inactive demyelinated lesions, when compared to NAWM. Simultaneously, CXCL12 (SDF1) expression was strongly increased in active, remyelinated and inactive demyelinated lesions, but increased expression of the IGF1 and IGF2 genes was found in inactive demyelinated lesions. This demonstrates that, in principle, expression of genes promoting oligodendrogliogenesis occurs in MS lesion tissue - even in inactive demyelinated lesions. In contrast, oligodendrogenesis inhibiting genes such as JAG1 were also expressed at higher levels in inactive demyelinated lesions. Both, oligodendrogliogenesis promoting as well as inhibiting genes are expressed in all lesion tissues. However, no clear promoting or inhibiting expression pattern could be detected in any of the different types of lesioned tissues. This might reflect the heterogeneity of lesion development in MS patients, both in terms of mechanisms and temporal differences. PMID- 29596846 TI - Event monitoring: Can we detect more than one event at a time? AB - A prior study by Wu and Wolfe found that the capacity for event monitoring (e.g. did an item change its state?) is more limited than for classic multiple object tracking. That limited capacity, K, could arise from either of two situations. It could be that people can detect K events simultaneously or it could be that they can successfully detect just one event at a time while monitoring K out of a total of N items. In the three different experiments of the present study, observers were asked to monitor a set of moving objects while watching for two critical events occurring in that set. Observers' performance can be well described by a model that includes an ability to detect two changes at once. Our results suggest that the capacity for event monitoring is further limited when tracking an additional event, but within the monitored set, people can detect at least two events simultaneously. PMID- 29596845 TI - Spontaneous respiratory plasticity following unilateral high cervical spinal cord injury in behaving rats. AB - Unilateral cervical C2 hemisection (C2Hx) is a classic model of spinal cord injury (SCI) for studying respiratory dysfunction and plasticity. However, most previous studies were performed under anesthesia, which significantly alters respiratory network. Therefore, the goal of this work was to assess spontaneous diaphragm recovery post-C2Hx in awake, freely behaving animals. Adult rats were chronically implanted with diaphragm EMG electrodes and recorded during 8 weeks post-C2Hx. Our results reveal that ipsilateral diaphragm activity partially recovers within days post-injury and reaches pre-injury amplitude in a few weeks. However, the full extent of spontaneous ipsilateral recovery is significantly attenuated by anesthesia (ketamine/xylazine, isoflurane, and urethane). This suggests that the observed recovery may be attributed in part to activation of NMDA receptors which are suppressed by anesthesia. Despite spontaneous recovery in awake animals, ipsilateral hemidiaphragm dysfunction still persists: i) Inspiratory bursts during basal (slow) breathing exhibit an altered pattern, ii) the amplitude of sighs - or augmented breaths - is significantly decreased, and iii) the injured hemidiaphragm exhibits spontaneous events of hyperexcitation. The results from this study offer an under-appreciated insight into spontaneous diaphragm activity and recovery following high cervical spinal cord injury in awake animals. PMID- 29596847 TI - An academic debate: OnabotulinumtoxinA for chronic migraine: PREEMPT-derived vs "customized" dosing/injection paradigm. AB - In 2010 onabotulinumtoxinA (OnabotA) was approved by the United States Food and Drug Administration for the treatment of chronic migraine (CM). Data supporting approval were derived primarily from two parallel placebo-controlled trials, the PREEMPT studies. Many clinicians and research investigators critical of those data have recommended that the dosing/injection paradigm for treating CM be "customized" to the needs of the individual patient rather than administered in a uniform fashion conforming to the methodology utilized in the PREEMPT studies. In this paper the authors debate the issue of whether treatment of CM with OnabotA should be standardized versus customized. PMID- 29596848 TI - Isolation and characterization of toxins from Xenorhabdus nematophilus against Ferrisia virgata (Ckll.) on tuberose, Polianthes tuberosa. AB - This study was aimed to evaluate the toxins of Xenorhabdus nematophilus bacterial isolate MDUStBa15 isolated from the nematode Steinernema carpocapsae that can parasitize two tailed mealybug Ferrisia virgata which is a new pest on tuberose. Soluble protein and organic fractions were characterized from cell free extract of X. nematophilus. Using SDS PAGE, presence of low molecular weight toxic proteins (12, 42 and 60 kDa) was observed in cell free extracts of X. nematophilus. Among these three proteins, 12 kDa was newly found in this study which showed anti-feedant activity and the maximum of 87.50% and 82.50% mortality of crawlers and adults of F. virgata, respectively at 72 h after treatment. GC-MS analysis of culture filtrates revealed the presence of five major compounds, all are exhibiting insecticidal property. Among several organic fractions, 1, 4 - epoxynaphthalene - 1 (2H) - methanol, 4,5,7-tris (1,1 - dimethylethyl) - 3,4 - dihydro; Pentacosane and Hexacosane were found in this study. Pot culture study revealed that an optimum dose of 5 ml/l of crude toxin caused the maximum mortality in crawlers (100%) and in adults (96.8%) of F. virgata at 72 h after spraying. In a field study application of 5 ml/l crude toxin along with biocontrol agent (Ladybird beetle - Cryptolaemus montrouzieri) registered the 90.55% mortality in crawlers and 73.60% mortality in adults of F. virgata at 7 days after spraying. The present study provides the clear evidence for the toxicity of protein; organic fraction and crude toxin which was obtained from X. nematophilus isolate MDUStBa15 against F. virgata on tuberose both in lab and field conditions. Hence, it can be utilised to manage the F. virgata on tuberose. PMID- 29596849 TI - Histochemical characteristics of regressing vessels in the hyaloid vascular system of neonatal mice: Novel implication for vascular atrophy. AB - The hyaloid vasculature constitutes a transitory system nourishing the internal structures of the developing eye, but the mechanism of vascular regression and its cell biological characteristics are not fully understood. The present study aimed to reveal the specificity of the hyaloid vessels by a systematic immunohistochemical approach for marker substances of myeloid cells and the extracellular matrix (ECM) in neonatal mice. Macrophages immunoreactive for F4/80, cathepsin D, and LYVE-1 gathered around the vasa hyaloidea propria (VHP), while small round cells in vascular lumen of VHP were selectively immunoreactive for galectin-3; their segmented nuclei and immunoreactivities for Ly-6G, CD11b, and myeloperoxidase indicated their neutrophilic origin. VHP possessed thick ECM and a dense pericyte envelope as demonstrated by immunostaining for laminin, type IV collagen, integrin beta1, and NG2. The galectin-3+ cells loosely aggregated with numerous erythrocytes in the lumen of hyaloid vessels in a manner reminiscent of vascular congestion. Galectin-3 is known to polymerize and form a complex with ECM and NG2 as well as recruit leukocytes on the endothelium. Observation of galectin-3 KO mice implicated the involvement of galectin-3 in the regression of hyaloid vasculature. Since macrophages may play central roles including blocking of the blood flow and the induction of apoptosis in the regression, galectin-3+ neutrophils may play a supportive role in the macrophage mediated involution of the hyaloid vascular system. PMID- 29596850 TI - Posterior stromal cell apoptosis triggered by mechanical endothelial injury and basement membrane component nidogen-1 production in the cornea. AB - This study was performed to determine whether cells in the posterior stroma undergo apoptosis in response to endothelial cell injury and to determine whether basement membrane component nidogen-1 was present in the cornea. New Zealand White rabbits had an olive tip cannula inserted into the anterior chamber to mechanically injure corneal endothelial cells over an 8 mm diameter area of central cornea with minimal injury to Descemet's membrane. At 1 h (6 rabbits) and 4 h (6 rabbits) after injury, three corneas at each time point were cryopreserved in OCT for terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay and immunohistochemistry (IHC) for vimentin and nidogen-1, and three corneas at each time point were fixed for transmission electron microscopy (TEM). Uninjured corneas were controls. Stromal cells over approximately the posterior 25% of the stroma overlying to the site of corneal endothelial injury underwent apoptosis detected by the TUNEL assay. Many of these apoptotic cells were vimentin+, suggesting they were likely keratocytes or corneal fibroblasts. Stromal cells peripheral to the site of endothelial injury and more anterior stromal cells overlying the site of endothelial injury did not undergo apoptosis. Stromal cell death was confirmed to be apoptosis by TEM. No apoptosis of stromal cells was detected in control, uninjured corneas. Nidogen-1 was detected in the stroma of unwounded corneas, with higher nidogen-1 in the posterior stroma than the anterior stroma. After endothelial scrape injury, concentrations of nidogen-1 appeared to be in the extracellular matrix of the posterior stroma and, possibly, within apoptotic bodies of stromal cells. Thus, posterior stromal cells, likely including keratocytes, undergo apoptosis in response to corneal endothelial injury, analogous to anterior keratocytes undergoing apoptosis in response to epithelial injury. PMID- 29596852 TI - Homeostasis despite instability. AB - We have shown previously that different homeostatic mechanisms in biochemistry create input-output curves with a "chair" shape. At equilibrium, for intermediate values of a parameter (often an input), a variable, Z, changes very little (the homeostatic plateau), but for low and high values of the parameter, Z changes rapidly (escape from homeostasis). In all cases previously studied, the steady state was stable for each value of the input parameter. Here we show that, for the feedback inhibition motif, stability may be lost through a Hopf bifurcation on the homeostatic plateau and then regained by another Hopf bifurcation. If the limit cycle oscillations are relatively small in the unstable interval, then the variable Z maintains homeostasis despite the instability. We show that the existence of an input interval in which there are oscillations, the length of the interval, and the size of the oscillations depend in interesting and complicated ways on the properties of the inhibition function, f, the length of the chain, and the size of a leakage parameter. PMID- 29596851 TI - Gills specific type 2 crustin isoforms: Its molecular cloning and characterization from kuruma shrimp Marsupenaeus japonicus. AB - Crustins are diverse group of antimicrobial peptides (AMPs) that have numerous isoforms mainly identified from hemocytes in decapods crustacean. However, little is known about its presence solely in gills tissue. In this study, we found two new crustin isoforms MjCRS8 and MjCRS9 by using transcriptome analysis from gills. Open reading frame of MjCRS8 and MjCRS9 were 593 bp and 459 bp encoding 197aa and 152aa, respectively. Tissue distribution analysis indicated that both MjCRS8 and MjCRS9 are expressed only in gills tissue. Multiple sequence alignment and phylogenetic analysis with previously reported crustin suggested that both MjCRS8 and MjCRS9 belong to type 2 crustin family. Experimental infection was conducted against Vibrio parahaemolyticus and white spot syndrome virus (WSSV) by immersion test. However, no significant upregulation was observed. PMID- 29596853 TI - Exenatide has a pronounced effect on energy intake but not energy expenditure in non-diabetic subjects with obesity: A randomized, double-blind, placebo controlled trial. AB - AIMS: Exenatide is a glucagon-like peptide 1 (GLP-1) mimetic which induces weight loss predominantly, it is presumed, via decreased food intake. However, circulating GLP-1 is also a determinant of energy expenditure. We sought to quantify the effect of exenatide on energy expenditure (EE) and energy intake. MATERIALS AND METHODS: In this single-center, randomized double-blind placebo controlled trial, we randomized 80 healthy, non-diabetic volunteers with obesity (46 women, age: 34.4 +/- 8.7 y, body fat by DXA: 44.2 +/- 7.8%) to subcutaneous exenatide 10 MUg twice daily or placebo. Subjects were admitted to our clinical research unit for measurement of 24 h-EE in a whole-room indirect calorimeter and ad libitum food intake using an automated vending machine paradigm before and after randomization. Furthermore, energy expenditure and ad libitum food intake measures were repeated at 24-week after readmission for 7-day inpatient stay. Body weight was obtained weekly for up to 5 weeks and was recorded at each monthly follow up visit up to 24 weeks. RESULTS: Prior to randomization, participants over ate during the 3-day vending machine period in the whole study group (114.6 +/- 35.2%), expressed as percentage of weight maintaining energy needs (WMEN) with those who were eventually randomized to exenatide overeating more (121.6 +/- 37.7%) compared to placebo group (107.6 +/- 31.5%). In the exenatide group, ad libitum absolute energy intake decreased by 1016.1 +/- 724.5 kcal/day (95% CI: -1250.9 to -781.2) versus a 245.1 +/- 710.5 kcal/day (95% CI: 475.4 to -14.7) decrease in placebo (Delta = -624.8 Kcal/day, p < 0.0001) whereas the reduction in ad libitum caloric intake relative to WMEN was a more modest 366.8 +/- 752.1 kcal/day (95% CI: -614.0 to -119.6) decrease compared to 8.0 +/- 860.1 kcal/day (95% CI: -286.8 to 270.8) reduction in placebo (Delta = -382.3 Kcal/day, p = 0.03). The decrease was uniform across all macronutrients groups. No differences in 24hEE or substrate oxidation rates were found. In the exenatide group, body weight decreased more over the 5 weeks (beta = -0.039 kg/week, p = 0.02) and was lower compared to placebo at the end of fifth week (-1.48 +/- 0.77 kg; 95% CI: -3.02 to 0.05, p = 0.06). At the 24-week follow up, there was no difference in energy intake between exenatide group and placebo group and the treatment group decreased 24-h EE more compared to placebo (beta = -160.6 Kcal/day, 95% CI: -307.6 to 13.6, p = 0.03) compared to their pre-randomization measurement. However, this reduction was not present after adjustment for changes in FM and FFM (beta = -87 kcal/day, p = 0.14). No difference was observed in body weight (Delta = -1.72 kg, 95% CI: -5.77 to 2.30, p = 0.39) in exenatide versus placebo over 24 weeks. CONCLUSION: Compared with placebo, exenatide decreased early ad libitum energy intake but did not change 24 h-EE. However, the reduction was more modest in relative versus absolute terms (i.e. below that needed for WMEN). Thus, although rate of weight change was greater in the exenatide treated subjects at 5 weeks, the absolute difference in weight was not significant. These findings indicate that although exenatide reduces food intake, it may be more beneficial in blunting overeating and thus may serve to more prevent weight regain following initial weight loss.

AB - When studying complex interconnected regulatory networks, effective methods for simultaneously manipulating multiple genes expression are paramount. Previously, we have developed a simple method for generation of an all-in-one CRISPR gRNA expression array. We here present a Golden Gate Assembly-based system of synergistic activation mediator (SAM) compatible CRISPR/dCas9 gRNA expression array for the simultaneous activation of multiple genes. Using this system, we demonstrated the simultaneous activation of the transcription factors, TWIST, SNAIL, SLUG, and ZEB1 a human breast cancer cell line. PMID- 29596854 TI - Brain and behavioral correlates of insulin resistance in youth with depression and obesity. AB - Depression, together with insulin resistance, is increasingly prevalent among youth. These conditions have traditionally been compartmentalized, but recent evidence suggests that a shared brain motivational network underlies their co occurrence. We posit that, in the context of depressive symptoms, insulin resistance is associated with aberrant structure and functional connectivity in the Anterior Cingulate Cortex (ACC) and hippocampus. This motivational neural circuit underlies dysfunctional behavioral responses and increased sensitivity to rewarding aspects of ingesting high calorie food that lead to disinhibition of eating even when satiated. To investigate this shared mechanism, we evaluated a sample of forty-two depressed and overweight (BMI > 85th%) youth aged 9 to 17. Using ACC and hippocampus structural and seed-based regions of interest, we investigated associations between insulin resistance, depression, structure (ACC thickness, and ACC and hippocampal area), and resting-state functional connectivity (RSFC). We predicted that aberrant associations among these neural and behavioral characteristics would be stronger in insulin resistant compared to insulin sensitive youth. We found that youth with greater insulin resistance had higher levels of anhedonia and more food seeking behaviors, reduced hippocampal and ACC volumes, and greater levels of ACC and hippocampal dysconnectivity to fronto-limbic reward networks at rest. For youth with high levels of insulin resistance, thinner ACC and smaller hippocampal volumes were associated with more severe depressive symptoms, whereas the opposite was true for youth with low levels of insulin resistance. The ACC-hippocampal motivational network that subserves depression and insulin resistance separately, may represent a critical neural interaction that link these syndromes together. PMID- 29596857 TI - Inversion effects for faces and objects in developmental prosopagnosia: A case series analysis. AB - The disproportionate face inversion effect (dFIE) concerns the finding that face recognition is more affected by inversion than recognition of non-face objects; an effect assumed to reflect that face recognition relies on special operations. Support for this notion comes from studies showing that face processing in developmental prosopagnosia (DP) is less affected by inversion than it is in normal subjects, and that DPs may even display face inversion superiority effects, i.e. better processing of inverted compared to upright faces. To date, however, there are no reports of direct comparisons between inversion effects for faces and objects, investigating whether the altered inversion effect in DP is specific to faces. We examined this question by comparing inversion effects for faces and cars in two otherwise identical recognition tasks in a group of DPs (N = 16) and a matched control group, using a case series design. Although both groups showed inversion effects for both faces and cars, only the control group exhibited a significant dFIE, i.e. a larger inversion effect for faces than cars. In comparison, the DPs were not significantly more affected by inversion than the control group when assessed with a face processing task that did not require recognition. Importantly, in both settings the DPs are better with upright than with inverted faces, and on the individual level no DP was found to perform significantly better with inverted than with upright faces. In fact, the DPs are impaired relative to the control group with both upright and inverted faces and to a less extent also with upright and inverted cars. These results yield no evidence of inversion superiority in DP but rather suggest that their face recognition problem is not limited to operations specialized for upright faces. PMID- 29596856 TI - Neural signatures of Trail Making Test performance: Evidence from lesion-mapping and neuroimaging studies. AB - The Trail Making Test (TMT) is an extensively used neuropsychological instrument for the assessment of set-switching ability across a wide range of neurological conditions. However, the exact nature of the cognitive processes and associated brain regions contributing to the performance on the TMT remains unclear. In this review, we first introduce the TMT by discussing its administration and scoring approaches. We then examine converging evidence and divergent findings concerning the brain regions related to TMT performance, as identified by lesion-symptom mapping studies conducted in brain-injured patients and functional magnetic resonance imaging studies conducted in healthy participants. After addressing factors that may account for the heterogeneity in the brain regions reported by these studies, we identify future research endeavours that may permit disentangling the different processes contributing to TMT performance and relating them to specific brain circuits. PMID- 29596858 TI - A novel histochemical method of simultaneous detection by a single- or double immunofluorescence and Bielschowsky's silver staining in teased rat sciatic nerves. AB - BACKGROUND: The Golgi silver method has been widely used in neuroscience for the study of normal and pathological morphology of neurons. The method has been steadily improved and Bielschowsky's silver staining method (BSSM) is widely used in various pathological conditions, like Alzheimer's disease. NEW METHOD: In this work, teased sciatic nerves were silver impregnated using BSSM. We also developed simultaneous staining by silver impregnation and single- or double immunofluorescence of the same section in teased nerve preparations. We immunostained against non-myelinating Schwann cells and different myelinating Schwann cell domains. RESULTS: BSSM teased nerves show a strong staining of axons (black) and a gold-brown staining of myelinating and non-myelinating Schwann cells. We were also able to stain by immunofluorescence these BSSM teased nerves with specific molecular markers against non-myelinating Schwann cells, also against non-compact myelin such as the Schmidt-Lanterman incisures or paranodal regions and compact myelin, but not axons. COMPARISON WITH EXISTING METHODS AND CONCLUSIONS: In peripheral nerves, several silver impregnation methods have been used to stain nerves in paraffin sections, but not in teased nerves to enable the assessment of isolated nerve fibers. In conclusion, BSSM gives accurate information of nerve morphology and combining the procedure with immunofluorescence it would be very useful to study the molecular nerve domain organization of the nerve fibers, and to study the molecular pathology of axon degeneration, or myelin disorders, or of any peripheral neuropathy, also to study demyelination diseases in the central nervous system. PMID- 29596859 TI - On application of kernel PCA for generating stimulus features for fMRI during continuous music listening. AB - BACKGROUND: There has been growing interest towards naturalistic neuroimaging experiments, which deepen our understanding of how human brain processes and integrates incoming streams of multifaceted sensory information, as commonly occurs in real world. Music is a good example of such complex continuous phenomenon. In a few recent fMRI studies examining neural correlates of music in continuous listening settings, multiple perceptual attributes of music stimulus were represented by a set of high-level features, produced as the linear combination of the acoustic descriptors computationally extracted from the stimulus audio. NEW METHOD: fMRI data from naturalistic music listening experiment were employed here. Kernel principal component analysis (KPCA) was applied to acoustic descriptors extracted from the stimulus audio to generate a set of nonlinear stimulus features. Subsequently, perceptual and neural correlates of the generated high-level features were examined. RESULTS: The generated features captured musical percepts that were hidden from the linear PCA features, namely Rhythmic Complexity and Event Synchronicity. Neural correlates of the new features revealed activations associated to processing of complex rhythms, including auditory, motor, and frontal areas. COMPARISON WITH EXISTING METHOD: Results were compared with the findings in the previously published study, which analyzed the same fMRI data but applied linear PCA for generating stimulus features. To enable comparison of the results, methodology for finding stimulus-driven functional maps was adopted from the previous study. CONCLUSIONS: Exploiting nonlinear relationships among acoustic descriptors can lead to the novel high-level stimulus features, which can in turn reveal new brain structures involved in music processing. PMID- 29596860 TI - Endothelial dysfunction, endothelial nitric oxide bioavailability, tetrahydrobiopterin, and 5-methyltetrahydrofolate in cardiovascular disease. Where are we with therapy? AB - Homeostasis around vascular endothelium is a function of the equilibrium between the bioavailability of nitric oxide (NO) and oxidizing reactive oxygen species (ROS). Within the vascular endothelium, NO enhances vasodilatation, reduces platelet aggression and adhesion (anti-thrombotic), prevents smooth muscle proliferation, inhibits adhesion of leukocytes and expression of pro-inflammatory cytokines genes (anti-inflammatory), and counters the oxidation of low density lipoprotein (LDL) cholesterol. A shift in the equilibrium that favours NO deficiency and ROS formation leads to endothelial dysfunction and cardiovascular disease. The synthesis of NO is catalysed by nitric oxide synthase and co factored by tetrahydrobiopterin (BH4), nicotinamide-adenine-dinucleotide phosphate (NADPH), flavin adenine dinucleotide (FAD), and flavin mononucleotide (FMN). The focus of this review is on endothelial nitric oxide synthase (eNOS), although we recognize that the other nitric oxide synthases may contribute as well. Levels of homocysteine and the active metabolite of folate, 5 methyltetrahydrofolate (5-MTHF), play a determining role in circulating levels of nitric oxide. We review endothelial nitric oxide bioavailabilty in relation to endothelial dysfunction as well as the therapeutic strategies involving the nitric oxide synthesis pathway. Although folate supplementation improves endothelial function, results from large clinical trials and meta-analyses on palpable clinical endpoints have been inconsistent. There are however, encouraging results from animal and clinical studies of supplementation with the co-factor for nitric oxide synthesis, BH4, though its tendency to be oxidized to dihydrobiopterin (BH2) remains problematic. Understanding how to maintain a high ratio of BH4 to BH2 appears to be the key that will likely unlock the therapeutic potential of nitric oxide synthesis pathway. PMID- 29596861 TI - Numerical simulation of heat transfer in blood flow altered by electroosmosis through tapered micro-vessels. AB - A numerical simulation is presented to study the heat and flow characteristics of blood flow altered by electroosmosis through the tapered micro-vessels. Blood is assumed as non-Newtonian (micropolar) nanofluids. The flow regime is considered as asymmetric diverging (tapered) microchannel for more realistic micro-vessels which is produced by choosing the peristaltic wave train on the walls to have different amplitudes and phase. The Rosseland approximation is employed to model the radiation heat transfer and temperatures of the walls are presumed constants. The mathematical formulation of the present problem is simplified under the long wavelength, low-Reynolds number and Debye-Huckel linearization approximations. The influence of various dominant physical parameters are discussed for axial velocity, microrotation distribution, thermal temperature distribution and nanoparticle volume fraction field. However, our foremost emphasis is to determine the effects of thermal radiation and coupling number on the axial velocity and microrotation distribution beneath electroosmotic environment. This analysis places a significant observation on the thermal radiation and coupling number which plays an influential role in hearten fluid velocity. This study is encouraged by exploring the nanofluid-dynamics in peristaltic transport as symbolized by heat transport in biological flows and also in novel pharmacodynamics pumps and gastro-intestinal motility enhancement. PMID- 29596862 TI - Phosphoinositides and their functions in apicomplexan parasites. AB - Phosphoinositides are the phosphorylated derivatives of the structural membrane phospholipid phosphatidylinositol. Single or combined phosphorylation at the 3, 4 and 5 positions of the inositol ring gives rise to the seven different species of phosphoinositides. All are quantitatively minor components of cellular membranes but have been shown to have important functions in multiple cellular processes. Here we describe our current knowledge of phosphoinositide metabolism and functions in apicomplexan parasites, mainly focusing on Toxoplasma gondii and Plasmodium spp. Even though our understanding is still rudimentary, phosphoinositides have already shown their importance in parasite biology and revealed some very particular and parasite-specific functions. Not surprisingly, there is a strong potential for phosphoinositide synthesis to be exploited for future anti-parasitic drug development. PMID- 29596863 TI - Analysis and prediction of presynaptic and postsynaptic neurotoxins by Chou's general pseudo amino acid composition and motif features. AB - Presynaptic neurotoxins and postsynaptic neurotoxins are two important neurotoxins isolated from venoms of venomous animals and have been proven to be potential effective in neurosciences and pharmacology. With the number of toxin sequences appeared in the public databases, there was a need for developing a computational method for fast and accurate identification and classification of the novel presynaptic neurotoxins and postsynaptic neurotoxins in the large databases. In this study, the Multinomial Naive Bayes Classifier (MNBC) had been developed to discriminate the presynaptic neurotoxins and postsynaptic neurotoxins based on the different kinds of features. The Minimum Redundancy Maximum Relevance (MRMR) feature selection method was used for ranking 400 pseudo amino acid (PseAA) compositions and 50 top ranked PseAA compositions were selected for improving the prediction results. The motif features, 400 PseAA compositions and 50 PseAA compositions were combined together, and selected as the input parameters of MNBC. The best correlation coefficient (CC) value of 0.8213 was obtained when the prediction quality was evaluated by the jackknife test. It was anticipated that the algorithm presented in this study may become a useful tool for identification of presynaptic neurotoxin and postsynaptic neurotoxin sequences and may provide some useful help for in-depth investigation into the biological mechanism of presynaptic neurotoxins and postsynaptic neurotoxins. PMID- 29596864 TI - Effect of Low Androgen Status on the Expression of P2Y Receptors in the Corpus Cavernosum of Rats. AB - OBJECTIVE: To determine whether low androgen status impacts erectile function by regulating the expression of the G protein-coupled P2Y receptors (P2Y1, P2Y2, P2Y4, and P2Y6) in the corpus cavernosum penis of rats. MATERIALS AND METHODS: A total of 36 healthy, 8-week-old, male Sprague-Dawley rats were randomly allocated into 6 groups: 4 weeks of androgen replacement therapy post castration (group A); 4 weeks post castration (group B); 4 weeks post sham operation (group C); 8 weeks of androgen replacement therapy post castration (group D); 8 weeks post castration (group E); and 8 weeks post sham operation (group F). The ratio of maximum intracavernous pressure/mean arterial pressure was measured for every group and detected the expression of P2Y1, P2Y2, P2Y4, and P2Y6 in the rat corpus cavernosum penis of every group. RESULTS: The ratio of maximum intracavernous pressure/mean arterial pressure significantly declined in the castration group compared with the control group (P <.01). The expression of P2Y1, P2Y2, P2Y4, and P2Y6 and the ratio of the phosphorylated endothelial nitric oxide synthase (eNOS)/eNOS proteins were significantly lower in the castration group vs treatment or control (P <.01) whereas they were significantly lower in the group of 8 weeks vs 4 weeks post castration (P <.05). The rat serum testosterone levels in every group were positively correlated with the protein levels of P2Y1, P2Y2, P2Y4, and P2Y6. CONCLUSION: Downregulation of the expression of the P2Y1, P2Y2, P2Y4, and P2Y6 receptors that reduces the ratio of phosphorylated eNOS/eNOS and eNOS activity may be one of the important mechanisms of erectile dysfunction caused by low androgen status.

PMID- 29596866 TI - Preliminary Report on Stone Breakage and Lesion Size Produced by a New Extracorporeal Electrohydraulic (Sparker Array) Discharge Device. AB - OBJECTIVE: To determine if an innovative extracorporeal electrohydraulic shock wave (SW) device (sparker array [SPA]) can effectively fracture artificial stones in vitro and in vivo, and if SPA treatment produces a renal lesion in our pig model of lithotripsy injury. Results of these experiments will be used to help evaluate the suitability of this device as a clinical lithotripter. MATERIALS AND METHODS: Ultracal-30 artificial stones were placed in a holder at the focus of the SPA and treated with 600 SWs (21.6 kV, 60 shocks/min). Stone fragments were collected, dried, and weighed to determine stone breakage. In vivo stone breakage entailed implanting stones into pigs. These stones were treated with 600 or 1200 SWs and the fragments were collected for analysis. Lesion analysis consisted of treating the left kidney of pigs with 1200 or 2400 SWs and quantitating the hemorrhagic lesion. RESULTS: In vitro, 71% +/- 2% of each artificial stone was fractured to <2 mm in size. In vivo stone breakage averaged 63%. Renal injury analysis revealed that only 1 of 7 kidneys showed evidence of hemorrhagic injury in the treated area. CONCLUSION: The SPA consistently comminuted artificial stones demonstrating its ability to fracture stones like other lithotripters. Also, the SPA caused little to no renal injury at the settings used in this study. These findings suggest further research is warranted to determine the potential of this device as a clinical lithotripter. PMID- 29596868 TI - Troponin T3 associates with DNA consensus sequence that overlaps with p53 binding motifs. AB - We recently reported that in addition to its classical cytoplasmic location, the fast skeletal muscle Troponin T3 (TnT3) shuttles to the nucleus, where it appears to perform nonclassical transcription regulatory functions. Importantly, changes in the composition of the nucleus-localized pool of TnT3 and its fragments contribute to age-dependent muscle damage and wasting. Here, using ChIP-Seq, we demonstrate that TnT3 associates with DNA consensus sequences including the TGCCT motif, which is required for p53 binding to the promoter area of p53-related genes. Gene set enrichment analysis further demonstrated that the p53 pathway was the most significantly enriched pathway among genes annotated to the TnT3 ChIP Seq peaks. We further demonstrated a strong correlation (r = 0.78, P = 1 * 10-4) between the expression levels of TNNT3 and TP53-inducible ribonucleotide reductase regulatory subunit M2B (RRM2B) in skeletal muscle tissue of 21 lean non diabetic human subjects and a significant (P < 0.05) reduction in the levels of both gene transcripts in the third age-tertile group [42.3-70 years of age (yoa)] as compared to the second age-tertile (31.3-42.3 yoa). Of note, both TNNT3 and RRM2B expression levels negatively associated with total body fat mass (each with r = 0.49, P < 0.05), whereas RRM2B positively correlated with pancreatic beta cell function (rRRM2B~HOMA-B = 0.47, P = 0.047). This work suggests that reduced TNNT3 gene expression is another mechanism leading to reduced TnT3 and excitation contraction coupling with aging. Consequently, TnT3 appears to contribute to age related sarcopenia and possibly other age-related deficiencies such as muscle insulin resistance and beta cell dysfunction by interacting with TnT3-binding sequences in the promoter area of p53-related genes, among others, and consequently modulating the transcriptional regulation of these target genes. PMID- 29596869 TI - Retraining of automatic action tendencies in individuals with obesity: A randomized controlled trial. AB - Obesity is a major health concern, characterized by an automatically activated tendency to (over)-eat. Recent research suggests that an effective way to counteract automatic approach tendencies in unhealthy consumption behavior might be approach bias modification. Therefore, we investigated an approach-avoidance training for unhealthy food cues in 189 patients with obesity of a psychosomatic inpatient clinic who were participating in a nutrition advice program. Patients in the active training group were trained to make avoidance movements (pushing a joystick) in response to unhealthy food pictures and approach movements (pulling the joystick) in response to positive pictures, while the control group received sham training (approaching and avoiding both picture types). Approach-avoidance bias, body mass index, eating pathology and food-specific implicit associations were assessed before and after the training. In line with our hypothesis, approach-avoidance bias improved in the active training group after the training, in comparison to the sham training group. Moreover, this effect generalized to new, untrained stimuli. However, no effects of the training were found in a food specific Single-Target Implicit Association Test, or on eating pathology questionnaires or body mass index. While the training results are promising, the effect of approach-avoidance bias modification on relevant behavior in obesity has yet to be established before it may be implemented as an add-on treatment. PMID- 29596870 TI - A qualitative investigation of how mothers from low income households perceive their role during family meals. AB - BACKGROUND: Having regular family meals has been shown to be protective for child dietary intake (e.g., higher intake of fruit and vegetables). Mothers appear to be most responsible for preparing family meals. Therefore, understanding how mothers perceive their roles around family meals may help identify ways in which to help more families have regular family meals. METHODS: United States mothers (n = 83) from the Twin Cities, Minnesota were interviewed during an in-home visit. Researchers trained in qualitative interviewing used a semi-structured approach and asked questions regarding the mothers' overall perception of their role during family meals. Interviews were coded using a mixed deductive and inductive content analysis approach. The majority of mothers were from minority and low-income households. RESULTS: Mothers described their roles during family meals as the follows: 1) Helping children make healthy choices at family meals; 2) Making the meal happen; 3) Monitoring children's food intake; 4) Managing behavior at the family meal; 5) Making the family meal atmosphere enjoyable; and 6) Facilitating conversation/communication. Two secondary research questions also emerged about the specifics of the mothers' perception of her role at family meals (i.e., How do mothers deal with fighting or arguing if it occurs at family meals? and What do mothers talk about with children at family meals?) CONCLUSIONS: Results show that mothers have a large and varied role during family meals. Additionally, they are willing to put effort into family meals and want them to be enjoyable. Findings also suggest that mothers can be supported by encouraging fuller family participation in family meals and by offering mothers quality nutrition and parent feeding practice information. PMID- 29596872 TI - Caveolin-1 deficiency protects pancreatic beta cells against palmitate-induced dysfunction and apoptosis. AB - Lipotoxicity leads to insulin secretion deficiency, which is among the important causes for the onset of type 2 diabetes mellitus. Thus, the restoration of beta cell mass and preservation of its endocrine function are long-sought goals in diabetes research. Previous studies have suggested that the membrane protein caveolin-1 (Cav-1) is implicated in beta-cell apoptosis and insulin secretion, however, the underlying mechanisms still remains unclear. Our objective is to explore whether Cav-1 depletion protects pancreatic beta cells from lipotoxicity and what are the underlying mechanisms. In this study, we found that Cav-1 silencing significantly promoted beta-cell proliferation, inhibited palmitate (PA)-induced pancreatic beta-cell apoptosis and enhanced insulin production and secretion. These effects were associated with enhanced activities of Akt and ERK1/2, which in turn downregulated the expression of cell cycle inhibitors (FOXO1, GSK3beta, P21, P27 and P53) and upregulated the expression of Cyclin D2 and Cyclin D3. Subsequent inhibition of PI3K/Akt and ERK/MAPK pathways abolished Cav-1 depletion induced beta-cell mass protection. Furthermore, under PA induced endoplasmic reticulum (ER) stress, Cav-1 silencing significantly reduced eIF2alpha phosphorylation and the expression of ER stress-responsive markers BiP and CHOP, which are among the known sensitizers of lipotoxicity. Our findings suggest Cav-1 as potential target molecule in T2DM treatment via the preservation of lipotoxicity-induced beta-cell mass reduction and the attenuation of insulin secretion dysfunction. PMID- 29596871 TI - Heat shock protein 60 involvement in vascular smooth muscle cell proliferation. AB - AIM: Heat shock protein 60 (Hsp60) is a mediator of stress-induced vascular smooth muscle cell (VSMC) proliferation. This study will determine, first, if the mitochondrial or cytoplasmic localization of Hsp60 is critical to VSMC proliferation and, second, the mechanism of Hsp60 induction of VSMC proliferation with a focus on modification of nucleocytoplasmic trafficking. METHODS AND RESULTS: Hsp60 was overexpressed in primary rabbit VSMCs with or without a mitochondrial targeting sequence (AdHsp60mito-). Both interventions induced an increase in VSMC PCNA expression and proliferation. The increase in VSMC PCNA expression and growth was not observed after siRNA-mediated knockdown of Hsp60 expression. Nuclear protein import in VSMC was measured by fluorescent microscopy using a microinjected fluorescent import substrate. Nuclear protein import was stimulated by both AdHsp60 and AdHsp60mito- treatments. AdHsp60 treatment also induced increases in nucleoporin (Nup) 62, Nup153, importin-alpha, importin-beta and Ran expression as well as cellular ATP levels compared to control. AdHsp60mito- treatment induced an up-regulation in importin-alpha, importin-beta and Ran expression compared to control. Hsp60 knockdown did not change nuclear protein import nor the expression of any nuclear transport receptors or nucleoporins. Both heat shock treatment and Hsp60 overexpression promoted the interaction of Ran with Hsp60. CONCLUSIONS: VSMC proliferation can be modulated via an Hsp60 dependent, cytosol localized mechanism that in part involves a stimulation of nuclear protein import through an interaction with Ran. This novel cellular signaling role for Hsp60 may be important in growth-based vascular pathologies like atherosclerosis and hypertension. PMID- 29596867 TI - The short-term stress response - Mother nature's mechanism for enhancing protection and performance under conditions of threat, challenge, and opportunity. AB - Our group has proposed that in contrast to chronic stress that can have harmful effects, the short-term (fight-or-flight) stress response (lasting for minutes to hours) is nature's fundamental survival mechanism that enhances protection and performance under conditions involving threat/challenge/opportunity. Short-term stress enhances innate/primary, adaptive/secondary, vaccine-induced, and anti tumor immune responses, and post-surgical recovery. Mechanisms and mediators include stress hormones, dendritic cell, neutrophil, macrophage, and lymphocyte trafficking/function and local/systemic chemokine and cytokine production. Short term stress may also enhance mental/cognitive and physical performance through effects on brain, musculo-skeletal, and cardiovascular function, reappraisal of threat/anxiety, and training-induced stress-optimization. Therefore, short-term stress psychology/physiology could be harnessed to enhance immuno-protection, as well as mental and physical performance. This review aims to provide a conceptual framework and targets for further investigation of mechanisms and conditions under which the protective/adaptive aspects of short-term stress/exercise can be optimized/harnessed, and for developing pharmacological/biobehavioral interventions to enhance health/healing, and mental/cognitive/physical performance. PMID- 29596873 TI - Highly efficacious and specific anti-glioma chemotherapy by tandem nanomicelles co-functionalized with brain tumor-targeting and cell-penetrating peptides. AB - Glioma is a highly challenging human malignancy as drugs typically exhibit a low blood-brain barrier (BBB) permeability as well as poor glioma selectivity and penetration. Here, we report that tandem nanomicelles co-functionalized with brain tumor-targeting and cell-penetrating peptides, Angiopep-2 and TAT, enable a highly efficacious and specific anti-glioma chemotherapy. Interestingly, tandem nanomicelles with 20 mol% Angiopep-2 and 10 mol% TAT linked via long and short poly(ethylene glycol)s, respectively, while maintaining a high glioma cell selectivity display markedly enhanced BBB permeation, glioma accumulation and penetration, and glioma cell uptake. We further show that docetaxel-loaded tandem nanomicelles have a long blood circulation time in mice and significantly better inhibit orthotopic U87MG human glioma than the corresponding Angiopep-2 single peptide-functionalized control, leading to an improved survival rate with little adverse effects. These tandem nanomicelles uniquely combining brain tumor targeting and cell-penetrating functions provide a novel and effective strategy for targeted glioma therapy. PMID- 29596874 TI - Controlling release from 3D printed medical devices using CLIP and drug-loaded liquid resins. AB - Mass customization along with the ability to generate designs using medical imaging data makes 3D printing an attractive method for the fabrication of patient-tailored drug and medical devices. Herein we describe the application of Continuous Liquid Interface Production (CLIP) as a method to fabricate biocompatible and drug-loaded devices with controlled release properties, using liquid resins containing active pharmaceutical ingredients (API). In this work, we characterize how the release kinetics of a model small molecule, rhodamine B base (RhB), are affected by device geometry, network crosslink density, and the polymer composition of polycaprolactone- and poly (ethylene glycol)-based networks. To demonstrate the applicability of using API-loaded liquid resins with CLIP, the UV stability was evaluated for a panel of clinically-relevant small molecule drugs. Finally, select formulations were tested for biocompatibility, degradation and encapsulation of docetaxel (DTXL) and dexamethasone-acetate (DexAc). Formulations were shown to be biocompatible over the course of 175 days of in vitro degradation and the clinically-relevant drugs could be encapsulated and released in a controlled fashion. This study reveals the potential of the CLIP manufacturing platform to serve as a method for the fabrication of patient specific medical and drug-delivery devices for personalized medicine.

AB - The hispid leaf beetle, Octodonta nipae (Maulik), (Coleoptera: Chrysomelidae), is a devastating pest of palm cultivation worldwide. Endosymbiotic bacteria in the genus Wolbachia are arguably one of the most abundant bacterial group associated with arthropods. Owing to its critical effects on host reproduction, Wolbachia has garnered much attention as a prospective future tool for insect pest management. However, their association, infection dynamics, and functionality remain unknown in this insect pest. Here, we diagnosis for the first time, the infection prevalence, and occurrence of Wolbachia in O. nipae. Experimental evidence by the exploration of wsp gene vindicate that O. nipae is naturally infected with bacterial symbiont of genus Wolbachia, showing a complete maternal inheritance with shared a common Wolbachia strain (wNip). Moreover, MLST (gatB, fbpA, coxA, ftsZ, and hcpA) analysis enabled the detections of new sequence type (ST-484), suggesting a particular genotypic association of O. nipae and Wolbachia. Subsequently, quantitative real-time PCR (qPCR) assay demonstrated variable infection density across different life stages (eggs, larvae, pupae and adult male and female), body parts (head, thorax, abdomen), and tissues (ovaries, testes, and guts). Infection density was higher in egg and female adult stage, as well as abdomen and reproductive tissues as compared to other samples. Interestingly, Wolbachia harbored dominantly in a female than the male adult, while, no significant differences were observed between male and female body parts and tissues. Phylogeny of Wolbachia infection associated with O. nipae rectified from all tested life stages were unique and fall within the same monophyletic supergroup-A of Wolbachia clades. The infection density of symbiont is among the valuable tool to understand their biological influence on hosts, and this latest discovery would facilitate the future investigations to understand the host-symbiont complications and its prospective role as a microbiological agent to reduce pest populations.

AB - In this paper, we have reported the synthesis, characterization, and evaluation of antimicrobial and antioxidant potential of monodispersed Zinc Oxide (ZnO) nanoparticles synthesized by the room temperature precipitation (aqueous phase) and polyol method (organic phase). ZnO nanoparticle synthesized by both the methods had shown excellent DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging, metal chelating (MC), ABTS (2,2'-azino-bis; 3-ethylbenzothiazoline-6 sulphonic acid), hydroxyl radical and superoxide radical scavenging activity (SAS). Scavenging activities were assayed within a concentration range of 25-75 ng ml-1. The antibacterial activities with MIC were investigated against two Gram positive bacteria Streptococcus mutans (MTCC 497) and S. pyogens (MTCC 1926); three Gram negative bacteria Vibrio cholerae (MTCC 3906), Shigella flexneri (MTCC 1457) and Salmonella typhii (MTCC 1252). ZnO nanoparticles synthesized by the polyol method showed better MIC values against both Gram-positive and Gram negative bacteria as compared to particles synthesized by aqueous precipitation method. Present study demonstrates the successful synthesis of ZnO nanoparticles with antioxidant property and significant broad spectrum antibacterial activity against several clinical bacterial pathogens.

AB - The peptides ocellatin-LB1, -LB2 and -F1 have previously been isolated from anurans of the Leptodactylus genus and the sequences are identical from residue 1 22, which correspond to ocellatin-LB1 sequence (GVVDILKGAAKDIAGHLASKVM-NH2), whereas ocellatin-LB2 carries an extra N and ocellatin-F1 extra NKL residues at their C-termini. These peptides showed different spectra of activities and biophysical investigations indicated a direct correlation between membrane disruptive properties and antimicrobial activities, i.e. ocellatin-F1 > ocellatin LB1 > ocellatin-LB2. To better characterize their membrane interactions, we report here the detailed three-dimensional NMR structures of these peptides in TFE-d2:H2O (60:40) and in the presence of zwitterionic DPC-d38 and anionic SDS d25 micellar solutions. Although the three peptides showed significant helical contents in the three mimetic environments, structural differences were noticed. When the structures of the three peptides in the presence of DPC-d38 micelles are compared to each other, a more pronounced curvature is observed for ocellatin-F1 and the bent helix, with the concave face composed mostly of hydrophobic residues, is consistent with the micellar curvature and the amphipathic nature of the molecule. Interestingly, an almost linear helical segment was observed for ocellatin-F1 in the presence of SDS-d25 micelles and the conformational differences in the two micellar environments are possibly related to the presence of the extra Lys residue near the peptide C-terminus, which increases the affinity of ocellatin-F1 to anionic membranes in comparison with ocellatin-LB1 and -LB2, as proved by isothermal titration calorimetry. To our knowledge, this work reports for the first time the three-dimensional structures of ocellatin peptides. PMID- 29596882 TI - SWI/SNF subunit expression heterogeneity in human aplastic anemia stem/progenitors. AB - Acquired aplastic anemia (AA) is a bone marrow (BM) failure associated with autoimmune destruction of hematopoietic stem cells (HSCs). Although somatic mutations have been identified in AA patients, mutations alone do not explain AA pathophysiology. SWI/SNF is an evolutionarily conserved, multi-subunit, ATP dependent chromatin-remodeling protein complex that plays an important role in mammalian hematopoiesis. Herein, gene expression analysis identified a significant loss of the SWI/SNF core component SMARCC1, along with ARID1B, ACTL6A, and SMARCD1, in human AA BM CD34+ HSCs and hematopoietic stem and progenitor cells (HSPCs) compared with normal HSPCs. However, expression of SMARCA4, SMARCB1, SMARCD3, and DPF2 remained intact in our AA cohort. PBRM1, BRD7, and SMARCA2 expression were significantly upregulated in both untreated and follow-up AA patients. Clonal hematopoiesis in AA is associated with evolution to late clonal disorders, including myelodysplastic syndromes (MDS). Apart from SMARCD1 loss, we did not observe significant alteration of SWI/SNF expression in MDS HSPCs, indicating SWI/SNF differential expression in AA and MDS. In addition, except for ACTL6A, SWI/SNF expression was unaltered in aged HSPCs. Importantly, our results provide evidence for loss of SWI/SNF in AA, and may implicate AA HSPC autonomous defective SWI/SNF regulation as an integral component of BM failure, in addition to autoimmune destruction of AA HSCs. These findings illustrate for the first time SWI/SNF subunit expression heterogeneity in human AA HSPCs and require prognostic validation in a larger cohort. PMID- 29596883 TI - Antagonistic activities of miR-148a and DNMT1: Ectopic expression of miR-148a impairs DNMT1 mRNA and dwindle cell proliferation and survival. AB - Functional analyses of noncoding RNAs have associated many micro RNAs (miRNA, miR) with various physiological processes, including proliferation, differentiation, development, cell metabolism, and apoptosis. Aberrant expression of miRNA and imbalance in their functions may lead to cellular aberration and different disease development, including cancer. In silico analysis of miRNA target prediction suggested that miR-148a possess a binding site in the 3' UTR of DNMT1 mRNA which can cause silencing of DNMT1 gene. Accordingly, we performed in vitro cell culture experiments to confirm the effect miR-148a on DNMT1 gene expression in prostate cancer cell lines. We demonstrated that there is a physical association between DNMT1 mRNA and miR-148a. We found that (i) ectopic expression of miR-148a induces programmed cell death and represses cell proliferation by targeting DNMT1; (ii) miR-148a gene is regulated by DNA methylation and DNMT1 in prostate cancer. We conclude that miR-148a is silenced by DNA methylation and ectopic expression of miR-148a suppresses DNMT1 expression and induced apoptotic genes expression in hormone-refractory prostate cancer cells. PMID- 29596885 TI - Significance of the mitochondrial thioredoxin reductase in cancer cells: An update on role, targets and inhibitors. AB - Thioredoxin reductase 2 (TrxR2) is a key component of the mitochondrial thioredoxin system able to transfer electrons to peroxiredoxin 3 (Prx3) in a reaction mediated by thioredoxin 2 (Trx2). In this way, both the level of hydrogen peroxide and thiol redox state are modulated. TrxR2 is often overexpressed in cancer cells conferring apoptosis resistance. Due to their exposed flexible arm containing selenocysteine, both cytosolic and mitochondrial TrxRs are inhibited by a large number of molecules. The various classes of inhibitors are listed and the molecules acting specifically on TrxR2 are extensively described. Particular emphasis is given to gold(I/III) complexes with phosphine, carbene or other ligands and to tamoxifen-like metallocifens. Also chemically unrelated organic molecules, including natural compounds and their derivatives, are taken into account. An important feature of many TrxR2 inhibitors is provided by their nature of delocalized lipophilic cations that allows their accumulation in mitochondria exploiting the organelle membrane potential. The consequences of TrxR2 inhibition are presented focusing especially on the impact on mitochondrial pathophysiology. Inhibition of TrxR2, by hindering the activity of Trx2 and Prx3, increases the mitochondrial concentration of reactive oxygen species and shifts the thiol redox state toward a more oxidized condition. This is reflected by alterations of specific targets involved in the release of pro-apoptotic factors such as cyclophilin D which acts as a regulator of the mitochondrial permeability transition pore. Therefore, the selective inhibition of TrxR2 could be utilized to induce cancer cell apoptosis. PMID- 29596884 TI - STIP1 is over-expressed in hepatocellular carcinoma and promotes the growth and migration of cancer cells. AB - Wnt/beta-catenin signaling is frequently activated in hepatocellular carcinoma (HCC). Better understanding the mechanism for its over-activation would help the therapy. In this study, we have shown that the stress-induced phosphoprotein 1 (STIP1) is up-regulated in the HCC tissues. Functional studies showed that STIP1 promoted the growth, colony formation and migration of cancer cells. However, knocking down the expression of STIP1 inhibited the growth, colony formation and migration of cancer cells. Molecular mechanism study showed that STIP1 interacted with Axin, enhanced the interaction between Axin and DVL2, thus activated beta catenin/TCF signaling. Taken together, our study demonstrated the oncogenic roles of STIP1 in the progression of HCC, and suggested that STIP1 might be a therapeutic target. PMID- 29596886 TI - Environmental and occupational exposure to resorcinol in Finland. AB - Resorcinol is a suspected endocrine disruptor that affects thyroid function by inhibiting thyroxin peroxidase. It may also have an impact on iodine uptake. Resorcinol has various uses; for example in the manufacture of rubber products and in wood adhesives, flame retardants, UV stabilizers, and dyes. It is also used in personal care products such as hair colorants, anti-acne preparations, and peels. The aim of this study was to assess both environmental background exposure and occupational exposure to resorcinol in Finland. We investigated occupational exposure in hairdresser work and in the manufacture of tyres, adhesive resins and glue-laminated timber by biomonitoring total resorcinol concentration in urine samples. The biomonitoring results were compared to the urinary levels of occupationally non-exposed volunteers, and to the biomonitoring equivalent (BE), which we estimated on the basis of the EFSA's acceptable daily intake (ADI) value for resorcinol. Almost all the urine samples (99%) of the non occupationally exposed volunteers contained measurable amounts of resorcinol. The urinary resorcinol data were rather scattered, and the resorcinol concentrations among women (GM 84 MUg/l, 95th percentile 2072 MUg/l) were clearly higher than the respective concentrations among men (GM 35 MUg/l, 95th percentile 587 MUg/l). The reason for this difference remains unclear. Although the two highest results exceeded the BE of 4 mg/l calculated on the basis of the EFSA's ADI, the 95th percentile of the occupationally non-exposed volunteers' results remained well below the BE among both males and females. According to the results, hairdressers' exposure to resorcinol was at the same level as that of the reference population of occupationally non-exposed volunteers. All hairdresser's values remained below the BE for resorcinol. The urinary resorcinol levels of the industrial workers were also at the same level as those of the reference population. We observed slight increases in the post-shift and evening samples of those working in the manufacture of tyres and adhesive resins. The results of some workers in the tyre manufacturing company exceeded the 95th percentile of non-occupationally exposed males, which was used as a biological guidance value for occupational exposure. Moreover, in this case exposure was below the health based biomonitoring equivalents. All the air samples collected in the companies contained very low resorcinol concentrations. It should be noted that the sample sizes for the male controls and industrial groups were small. PMID- 29596888 TI - Squalene epoxidase as a promising metabolic target in cancer treatment. AB - Oncogenic alteration of the cholesterol synthesis pathway is a recognized mechanism of metabolic adaptation. In the present review, we focus on squalene epoxidase (SE), one of the two rate-limiting enzymes in cholesterol synthesis, retracing its history since its discovery as an antimycotic target to its description as an emerging metabolic oncogene by amplification with clinical relevance in cancer. We review the published literature assessing the association between SE over-expression and poor prognosis in this disease. We assess the works demonstrating how SE promotes tumor cell proliferation and migration, and displaying evidence of cancer cell demise in presence of human SE inhibitors in in vitro and in vivo models. Taken together, robust scientific evidence has by now accumulated pointing out SE as a promising novel therapeutic target in cancer treatment. PMID- 29596887 TI - Derivation of an inhalation TTC for the workplace based on DNEL values reported under REACH. AB - The Threshold of Toxicological Concern (TTC) concept defines a generic tolerable exposure for chemicals of unknown toxicity below which the risk of adverse health effects is considered very small. The original concept was refined and extended over the years, based either on differentiated structural classes or on additional information on certain toxicological endpoints. Initially, the focus of the TTC application was only on systemic toxic effects after repeated oral intake and consisted of one value. However, under well-defined boundary conditions, a long-term systemic inhalation TTC could also serve as a cut-off criterion for occupational exposure in those cases where workers are exposed to very low levels of chemicals by inhalation contact and could therefore reduce the need to perform animal tests. Within the scope of the European REACH legislation, several thousand systemic long-term inhalation Derived No Effect Levels (DNELs) for workers have been published. By statistical evaluation of the DNEL distribution of 1876 chemicals and the resulting 99th percentiles, we propose an inhalation workplace TTC for systemic effects in the region of 50 MUg/m3 (7 MUg/kg body weight/day). Specific exclusion criteria apply for the discussed concept. PMID- 29596889 TI - Pro-apoptotic Bax promotes mesenchymal-epithelial transition by binding to respiratory complex-I and antagonizing the malignant actions of pro-survival Bcl 2 proteins. AB - The plasticity of solid tumors between the epithelial and mesenchymal states critically influences their malignant progression and metastasis. The epithelial mesenchymal transition (EMT), which supports cancer cell invasion and metastasis, is promoted by pro-survival members (e.g., Bcl-2 and Bcl-XL) of the Bcl-2 protein family, which are well-known key apoptosis regulators. We found that Bcl-w, another pro-survival member, promotes EMT by increasing respiratory complex-I activity and reactive oxygen species (ROS) levels. In contrast, pro-apoptotic Bax facilitates mesenchymal-epithelial transition by binding to complex-I, which inhibits complex-I-induced ROS production. Functional antagonism between pro survival and pro-apoptotic proteins in regulating tumor plasticity was directly confirmed by co-expressing Bax with Bcl-w or Bcl-XL. Therefore, the balance between the functionally opposing Bcl-2 proteins appears to be a critical determinant of cancer cell phenotypes. We further showed that sub-lethal doses of gamma-radiation induced EMT by increasing Bcl-XL and Bcl-w levels and complex-I activity. We propose that Bcl-2 proteins and complex-I are potential targets for preventing tumor progression and the malignant actions of radiotherapy. PMID- 29596890 TI - Immuno-modulators enhance antigen-specific immunity and anti-tumor effects of mesothelin-specific chimeric DNA vaccine through promoting DC maturation. AB - As a tumor antigen, mesothelin (MSLN) can be identified in various malignancies. MSLN is potential for antigen-specific cancer vaccines. We generated a novel chimeric DNA vaccine using antigen-specific connective tissue growth factor lined with MSLN (CTGF/MSLN). The anti-tumor effects of the CTGF/MSLN DNA vaccine combined with anti-CD40 Ab and toll-like receptor 3 ligand-poly(I:C) were validated in an MSLN-expressing model. CTGF/MSLN DNA with anti-CD40Ab and poly(I:C) vaccinated mice demonstrated potent anti-tumor effects with longer survival and less tumor volumes. An increase in MSLN-specific CD8+ T cells and anti-MSLN Ab titers was also noted in CTGF/MSLN DNA with anti-CD40Ab and poly(I:C) vaccinated mice. The CTGF/MSLN DNA vaccine combined with immuno modulator EGCG also generated potent anti-tumor effects. Immuno-modulators could enhance the antigen-specific anti-tumor effects of CTGF/MSLN DNA vaccine through promoting the DC maturation. In addition, MSLN-specific cell-based vaccine with AAV-IL-12 and the CTGF/MSLN DNA vaccine with anti-CD40Ab/polyp(I:C) generated more potent anti-tumor effects than the other combinational regimens. The results indicate that an MSLN-specific DNA vaccine combined with immuno-modulators may be an effective immunotherapeutic strategy to control MSLN-expressing tumors including ovarian and pancreastic cancers, and malignant mesothelioma. PMID- 29596891 TI - Connexin 43 regulates the expression of wound healing-related genes in human gingival and skin fibroblasts. AB - Fibroblasts are the most abundant connective tissue cells and play an important role in wound healing. It is possible that faster and scarless wound healing in oral mucosal gingiva relative to skin may relate to the distinct phenotype of the fibroblasts residing in these tissues. Connexin 43 (Cx43) is the most ubiquitous Cx in skin (SFBLs) and gingival fibroblasts (GFBLs), and assembles into hemichannels (HCs) and gap junctions (GJs) on the cell membrane. We hypothesized that SFBLs and GFBLs display distinct expression or function of Cx43, and that this may partly underlie the different wound healing outcomes in skin and gingiva. Here we show that Cx43 distinctly formed Cx43 GJs and HCs in human skin and gingiva in vivo. However, in SFBLs, in contrast to GFBLs, only a small proportion of total Cx43 assembled into HC plaques. Using an in vivo-like 3D culture model, we further show that the GJ, HC, and channel-independent functions of Cx43 distinctly regulated wound healing-related gene expression in GFBLs and SFBLs. Therefore, the distinct wound healing outcomes in skin and gingiva may partly relate to the inherently different assembly and function of Cx43 in the resident fibroblasts. PMID- 29596892 TI - Dysfunction of cholesterol sensor SCAP promotes inflammation activation in THP-1 macrophages. AB - Crosstalk occurs between dyslipidemia and chronic inflammation, which are both precipitants of atherosclerosis. Sterol regulatory element binding proteins cleavage-activating protein (SCAP) plays a key role in regulating cholesterol homeostasis. The present study investigated the effects of SCAP dysfunction on the expression of inflammatory cytokines and lipid metabolism in THP-1 macrophages. Intracellular cholesterol content was assessed by Oil Red O staining and quantitative assays. The expression of SCAP, HMGCR, pro-IL-1beta and N SREBP2, p65(N) in the nucleus were examined by real-time quantitative RT-PCR and Western blotting. The level of secretary proteins IL-1beta, TNF-alpha and MCP-1 in the supernatants were determined by ELISA. The translocation of SCAP from the endoplasmic reticulum (ER) to the Golgi was detected by confocal microscopy. Our results demonstrated that over-expression of SCAP significantly increased the expression of HMGCR, pro-IL-1beta in the cytoplasm, and mature IL-1beta, TNF alpha, MCP-1 in the supernatants, while knocking down SCAP dramatically decreased the expression of these molecules. Betulin effectively suppressed the accumulation of intracellular cholesterol in the SCAP over-expressed THP-1 macrophages, but did not affect the expression of inflammatory cytokines, indicating that the pro-inflammatory effect of SCAP was independent of its routine role in regulating cholesterol homeostasis. Furthermore, we investigated the molecular mechanisms mediating the crosstalk between dyslipidemia and inflammatory responses. Knocking down SCAP attenuated LPS-induced IkappaB phosphorylation and reduced the nuclear level of p65, while over-expression of SCAP increased the nuclear level of p65. Knocking down p65 abolished the proinflammatory effect represented by elevated expression of the inflammatory mediators in the SCAP over-expressed THP-1 macrophages, suggesting that SCAP dysfunction stimulated inflammatory responses via activating the NF-kappaB signaling pathway. In conclusion, the cholesterol sensor SCAP plays a role in regulating the expression of inflammatory factors such as IL-1beta, TNF-alpha, and MCP-1 in THP-1 macrophages. SCAP mediates the inflammatory response via activating the NF-kappaB pathway. This new function of SCAP is independent of its role in lipid metabolism. PMID- 29596893 TI - Tumor microenvironment in functional adrenocortical adenomas: immune cell infiltration in cortisol-producing adrenocortical adenoma. AB - The tumor microenvironment plays pivotal roles in various human neoplasms. However, that of benign tumor, particularly hormone-secreting endocrine tumors, has remained virtually unknown. Therefore, we firstly attempted to analyze the tumor microenvironment of autonomous hormone-secreting adrenocortical adenomas. We first histologically evaluated 21 cortisol-producing adrenocortical adenoma (CPA) and 13 aldosterone-producing adrenocortical adenoma (APA) cases. Quantitative histologic analysis revealed that intratumoral immune cell infiltration (ICI) was more pronounced in CPAs than in APAs. We then evaluated the cytokine and chemokine profiles using polymerase chain reaction arrays in APAs and CPAs. Angiogenic chemokines, C-X-C motif chemokine ligand (CXCL) 1 and CXCL2, were significantly more abundant in CPAs than in APAs using subsequent quantitative polymerase chain reaction and immunohistochemical analyses. We then examined the vascular density between these 2 adenomas, and the density was significantly higher in overt CPAs than in APAs. Of particular interest, CXCL12 positive vessels were detected predominantly in CPAs, and their infiltrating immune cells were C-X-C motif chemokine receptor 4 (CXCR4) positive. These results above indicated that CXCL12-CXCR4 signaling could partly account for ICI detected predominantly in CPAs. We then further explored the etiology of ICI in CPAs by evaluating the senescence of tumor cells possibly caused by excessive cortisol in CPAs. The status of senescence markers, p16 and p21, was significantly more abundant in CPAs than in APAs. In addition, all CPA cases examined were positive for senescence-associated beta-galactosidase. These results all indicated that exposure to local excessive cortisol could result in senescence of tumors cells and play essential roles in constituting the characteristic tissue microenvironment of CPAs. PMID- 29596894 TI - Pancreatic neuroendocrine carcinomas reveal a closer relationship to ductal adenocarcinomas than to neuroendocrine tumors G3. AB - Pancreatic neuroendocrine carcinoma is a rare aggressive tumor commonly harboring TP53 and RB1 alterations and lacking neuroendocrine-related genetic changes such as mutations in MEN1 and ATRX/DAXX. Little is known about its genetic profile with regard to that of pancreatic ductal adenocarcinoma. We therefore conducted a detailed genetic study in 12 pancreatic neuroendocrine carcinomas of large cell (n = 9) and small cell type (n = 3) using massive parallel sequencing applying a 409-gene panel on an Ion Torrent system. The genetic data were compared with known data of pancreatic ductal adenocarcinoma and correlated with exocrine lineage marker expression. A similar analysis was performed in 11 pancreatic neuroendocrine tumors G3. Neuroendocrine carcinomas harbored 63 somatic mutations in 45 different genes, affecting most commonly TP53 (8/12 cases), KRAS (5/12 cases), and RB1 (loss of expression with or without deletion in 4/12 cases). Five carcinomas had both TP53 and KRAS mutations. Neuroendocrine tumors G3 only shared singular mutations in 5 different genes with neuroendocrine carcinomas, including TP53, CDKN2A, ARID1A, LRP1B, and APC, affecting 5 different cases. Most KRAS positive neuroendocrine carcinomas also expressed MUC1 (4/5) and carcinoembryonic antigen (3/5) as markers of ductal differentiation. Our data indicate that almost half of the pancreatic neuroendocrine carcinomas are genetically and phenotypically related to pancreatic ductal adenocarcinoma, and might therefore respond to chemotherapies targeting the latter carcinomas. PMID- 29596895 TI - Microscopic ileitis in diverted and nondiverted enteric segments: an underrecognized condition with a multifactorial etiology. AB - Microscopic ileitis has been infrequently reported in the literature with the few reported cases usually associated with concurrent microscopic colitis. Having encountered a case of collagenous ileitis involving the diverted distal limb of a loop ileostomy and sparing the proximal limb, we examined additional cases of loop ileostomy, end ileostomy, colostomy, and the accompanying diverted colorectal segment for features of microscopic ileitis and colitis. A total of 101 cases of diverted and nondiverted enteric segments were examined from 37 loop ileostomies, 16 end ileostomies, and 12 colostomies status post-Hartmann's procedure. The patients' clinical histories, including demographics and risk factors for microscopic colitis, were obtained from electronic medical records. The index case and an additional case showed collagenous ileitis: the former in the diverted distal limb, and the latter in the nondiverted proximal limb of the loop ileostomy. The latter was associated with high ileostomy output with watery diarrhea. Two additional cases showed lymphocytic ileitis: one in the nondiverted proximal limb of loop ileostomy and the other in the end ileostomy. All 4 patients had one or more risk factors for microscopic colitis. The etiology of microscopic ileitis seems to be multifactorial, and microscopic ileitis may be underdiagnosed. The diverted enteric segment may be involved by microscopic enteritis, suggesting that additional factors other than fecal stasis and altered bacterial flora may be contributing to its pathogenesis. When microscopic ileitis is encountered, identifying associated risk factors, recognizing incipient clinical symptoms of microscopic colitis, and considering other associated diseases or conditions are warranted. PMID- 29596896 TI - Minute mesenchymal chondrosarcoma within osteochondroma: an unexpected diagnosis confirmed by HEY1-NCOA2 fusion. AB - Mesenchymal chondrosarcoma is rare and can be challenging to diagnose. Herein, we report a minute mesenchymal chondrosarcoma within an osteochondroma. A 12-year old girl presented with an asymptomatic exophytic lesion of the rib. The tumor was clinically diagnosed as osteochondroma and was excised after observation for 3 years. The resected specimen revealed an unexpected minute (0.9 cm) "monophasic" mesenchymal chondrosarcoma in the apex of the lesion. The sarcoma consisted of monomorphic spindle cells without hyaline cartilage. Fluorescence in situ hybridization detected NCOA2 rearrangement, and reverse-transcription polymerase chain reaction and sequencing detected a HEY1 (exon 4)-NCOA2 (exon 13) fusion transcript. The patient did not receive adjuvant therapy and is alive with no recurrence 6 years after surgery. The present case highlights the value of careful pathological examination of specimens submitted as osteochondroma and emphasizes the usefulness of molecular assays in the diagnosis of mesenchymal chondrosarcoma in an atypical setting. PMID- 29596898 TI - Histamine-deficient mice do not respond to the antidepressant-like effects of oleoylethanolamide. AB - It has been suggested that the bioactive lipid mediator oleoylethanolamide (OEA), a potent agonist of the peroxisome proliferator-activated receptor-alpha (PPAR alpha) possesses anti-depressant-like effects in several preclinical models. We recently demonstrated that several of OEA's behavioural actions require the integrity of the brain histaminergic system, and that an intact histaminergic neurotransmission is specifically required for selective serotonin re-uptake inhibitors to exert their anti-depressant-like effect. The purpose of our study was to test if OEA requires the integrity of the histaminergic neurotransmission to exert its antidepressant-like effects. Immobility time in the tail suspension test was measured to assess OEA's potential (10 mg/kg i.p.) as an antidepressant drug in histidine decarboxylase null (HDC-/-) mice and HDC+/+ littermates, as well as in PPAR-alpha+/+ and PPAR-alpha-/- mice. CREB phosphorylation was evaluated using Western blot analysis in hippocampal and cortical homogenates, as pCREB is considered partially responsible for the efficacy of antidepressants. Serotonin release from ventral hippocampi of HDC+/+ and HDC-/- mice was measured with in-vivo microdialysis, following OEA administration. OEA decreased immobility time and increased brain pCREB levels in HDC+/+ mice, whereas it was ineffective in HDC-/- mice. Comparable results were obtained in PPAR-alpha+/+ and PPAR-alpha-/- mice. Microdialysis revealed a dysregulation of serotonin release induced by OEA in HDC-/- mice. Our observations corroborate our hypothesis that brain histamine and signals transmitted by OEA interact to elaborate appropriate behaviours and may be the basis for the efficacy of OEA as an antidepressant-like compound. PMID- 29596897 TI - Mechanisms of neurotrophin trafficking via Trk receptors. AB - In neurons, long-distance communication between axon terminals and cell bodies is a critical determinant in establishing and maintaining neural circuits. Neurotrophins are soluble factors secreted by post-synaptic target tissues that retrogradely control axon and dendrite growth, survival, and synaptogenesis of innervating neurons. Neurotrophins bind Trk receptor tyrosine kinases in axon terminals to promote endocytosis of ligand-bound phosphorylated receptors into signaling endosomes. Trk-harboring endosomes function locally in axons to acutely promote growth events, and can also be retrogradely transported long-distances to remote cell bodies and dendrites to stimulate cytoplasmic and transcriptional signaling necessary for neuron survival, morphogenesis, and maturation. Neuronal responsiveness to target-derived neurotrophins also requires the precise axonal targeting of newly synthesized Trk receptors. Recent studies suggest that anterograde delivery of Trk receptors is regulated by retrograde neurotrophin signaling. In this review, we summarize current knowledge on the functions and mechanisms of retrograde trafficking of Trk signaling endosomes, and highlight recent discoveries on the forward trafficking of nascent receptors. PMID- 29596899 TI - Proteomic characterization of hippocampus of chronically socially isolated rats treated with fluoxetine: Depression-like behaviour and fluoxetine mechanism of action. AB - Due to the severity of depressive symptoms, there remains a necessity in defining the underlying mechanisms of depression and the precise actions of antidepressants in alleviating these symptoms. Proteomics is a powerful and promising tool for discovering novel pathways of cellular responses to disease and treatment. As chronic social isolation (CSIS) is a valuable animal model for studying depression, we performed a comparative subproteomic study of rat hippocampus to explore the effect of six weeks of CSIS and the therapeutic effect of chronic fluoxetine (Flx) treatment (last three weeks of CSIS; 15 mg/kg/day). Behaviorally, Flx treatment normalized the decreased sucrose preference and increased marble burying results resulting from CSIS, indicative of a FLX-induced attenuation of both anhedonia and anxiety. An analysis of cytosolic and nonsynaptic mitochondrial subproteome patterns revealed that CSIS resulted in down-regulation of proteins involved in mitochondrial transport and energy processes, primarily tricarboxylic acid (TCA) cycle and oxidative phosphorylation. Chronic Flx treatment resulted in an up-regulation of CSIS altered proteins and additional expression of other transporter and energy involved proteins. Immunohistochemical analysis revealed hippocampal subregion specific effects of CSIS and/or Flx treatment on selective protein expressions. PMID- 29596900 TI - Role of nitric oxide and WNK-SPAK/OSR1-KCC2 signaling in daily changes in GABAergic inhibition in the rat dorsal raphe neurons. AB - Serotonergic neurons in the dorsal raphe nucleus (DRN) act as wake-inducing neurons in the sleep-wake cycle and are controlled by gamma-aminobutyric acid (GABA) synaptic inputs. We investigated daily changes in GABAergic inhibition of the rat DRN neurons and the role of nitric oxide (NO) and cation-chloride co transporters in the GABAergic action. Neuronal NO synthase (nNOS) was co expressed in 74% of serotonergic DRN neurons and nNOS expression was higher during daytime (the sleep cycle) than that during nighttime (the wake cycle). GABAergic hyperpolarization of DRN neurons produced by GABAA receptor agonist muscimol was greater and the equilibrium potential of muscimol showed a hyperpolarizing shift during daytime compared to that during nighttime. Expression levels of potassium-chloride co-transporter 2 (KCC2) were higher during daytime than that during nighttime, whereas there were no changes in sodium-potassium-chloride co-transporter 1 (NKCC1) expression. With-no-lysine kinase (WNK) isoform 1 was more highly expressed during daytime than that during nighttime. Total Ste20-related proline alanine rich kinase (SPAK) and oxidative stress response kinase 1 (OSR1) were also higher during daytime than during nighttime, while there were no changes in phosphorylated SPAK and OSR1. Consistent with the findings during the sleep-wake cycle, ex vivo treatment of DRN slices with a NO donor sodium nitroprusside (SNP) increased the expression of KCC2, WNK1, WNK2, WNK3, SPAK, and OSR1, whilst decreasing phosphorylated SPAK. These results suggest that GABAergic synaptic inhibition of DRN serotonergic neurons shows daily changes during the sleep-wake cycle, which might be regulated by daily changes in nNOS-derived NO and WNK-SPAK/OSR1-KCC2 signaling.

AB - Stimulation of the midbrain periaqueductal gray matter (PAG) in humans elicits sensations of fear and impending terror, and mediates predator defensive responses in rodents. In rats, pharmacological stimulation of the dorsolateral portion of the PAG (dlPAG) with N-Methyl-d-Aspartate (NMDA) induces aversive conditioning that acts as an unconditioned stimulus (US). In the present work, we investigated the interplay between the vanilloid TRPV1 and cannabinoid CB1 receptors in the NMDA-dlPAG defensive response and in subsequent aversive learning. Rats were subjected to dlPAG NMDA infusion in an olfactory conditioned stimulus (CS) task allowing the evaluation of immediate and long-term defensive behavioral responses during CS presentation. The results indicated that an intermediate dose of NMDA (50 pmol) induced both immediate and long-term effects. A sub-effective dose of NMDA (25 pmol) was potentiated by the TRPV1 receptor agonist capsaicin (CAP, 1 nmol) and the CB1 receptor antagonist, AM251 (200 pmol). CAP (10 nmol) or the combination of CAP (1 nmol) and AM251 (200 pmol) induced long-term effects without increasing immediate defensive responses. The glutamate release inhibitor riluzole (2 or 4 nmol) and the AMPA/kainate receptor antagonist DNQX (2 or 4 nmol) potentiated the immediate effects but blocked the long-term effects. The results showed that immediate defensive responses rely on NMDA receptors, and aversive learning on the fine-tuning of TRPV1, CB1, metabotropic glutamate and AMPA receptors located in pre- and postsynaptic membranes. In conclusion, the activity of the dlPAG determines core affective aspects of aversive memory formation controlled by local TRPV1/CB1 balance. PMID- 29596902 TI - Ceftolozane/tazobactam dose regimens in severely/morbidly obese patients with complicated intra-abdominal infection or complicated urinary tract infection. AB - Ceftolozane/tazobactam is approved for treatment of complicated intra-abdominal infection (cIAI) and complicated urinary tract infection (cUTI) with renal function-based dose adjustment. Given that creatinine clearance, body weight and sex are highly correlated in severely/morbidly obese patients, this study investigated whether approved dosing regimens for ceftolozane/tazobactam are appropriate in severely/morbidly obese patients based on simulated pharmacokinetic/pharmacodynamic target attainment, with confirmation from observed clinical outcomes data from the phase 3 clinical development programme. Using a previously published population pharmacokinetic model, 1000 patients were randomly sampled from an internal pooled database of 201 severely/morbidly obese patients (BMI >= 35 kg/m2) and were used for Monte Carlo simulation to test whether the labelled dose regimens can achieve >=90% probability of a target of 32.2% (1-log kill) time above free ceftolozane concentration against pathogens at an MIC up to 8 mg/L. Clinical outcomes data for severely/morbidly obese patients with cIAI or cUTI from pivotal phase 3 studies were summarised to calculate clinical and composite cure rates as a complimentary support. With the approved renal function-based dosing regimens, >90% target attainment of bactericidal activity was achieved at MICs up to 8 mg/L in the simulated severely/morbidly obese patients with cIAI or cUTI, similar to target attainment in non-obese patients and further confirmed by phase 3 outcomes where cure rates in severely/morbidly obese patients and non-obese patients are similar. Approved dosing regimens of ceftolozane/tazobactam, adjusted according to renal function, can achieve adequate target attainment and high clinical cure rates in severely/morbidly obese patients with cIAI or cUTI. PMID- 29596903 TI - High prevalence of 16S rRNA methyltransferases among carbapenemase-producing Enterobacteriaceae in the UK and Ireland. AB - The emergence of 16S rRNA methyltransferases (16S RMTases) worldwide is a growing concern due to their ability to confer high-level resistance (minimum inhibitory concentrations (MICs) >256 mg/L) to all clinically relevant aminoglycosides. As the occurrence of 16S RMTases in the United Kingdom has not been investigated to date, we screened 806 Enterobacteriaceae isolates displaying high-level aminoglycoside resistance (amikacin, gentamicin and tobramycin MICs >=64, >=32 and >=32 mg/L, respectively) for 16S RMTases either by analysing whole-genome sequence (WGS) data (which were available for 449 isolates) or by polymerase chain reaction. A total of 94.5% (762/806) pan-aminoglycoside-resistant Enterobacteriaceae were positive for one or more 16S RMTase genes; armA was the most common (340, 44.6%) followed by rmtC (146, 19.2%), rmtF (137, 18.0%), rmtB (87, 11.4%) and various two-gene combinations (52, 6.8%). Most (93.4%; 712/762) 16S RMTase producers also carried acquired carbapenemase genes, with blaNDM the most common (592/712; 83.1%). Additionally, high-risk bacterial clones associated with blaNDM were identified in the subset of isolates with WGS data. These included Escherichia coli sequence types (STs) 405 (21.8%, 19/87), 167 (20.7%, 18/87) 410 (12.6%, 11/87) and K. pneumoniae STs 14 (35.6%, 112/315), 231 (15.6%, 49/315) and 147 (10.5%, 33/315). These accounted for 4.2% (15/358), 5.0% (18/358), 3.1% (11/358), 28.2% (101/358), 3.1% (11/358) and 7.0% (25/358) blaNDM producing isolates, respectively. This study shows that 16S RMTases occur in the UK and Ireland and carbapenemases are particularly prevalent in 16S RMTase producing Enterobacteriaceae. This association poses a risk to the treatment of multidrug-resistant Gram-negative infections in the clinical setting. PMID- 29596904 TI - A Single-Arm Phase II Trial of Lenalidomide in Relapsing or Refractory Primary Cutaneous Large B-Cell Lymphoma, Leg Type. AB - Although the combination of rituximab and polychemotherapy has improved prognosis of primary cutaneous diffuse large B-cell lymphoma, leg type, the advanced age of patients limits therapeutic options in relapsing/refractory cases. A multicenter, single-arm, phase II trial was conducted to assess the benefits and safety of lenalidomide in refractory/relapsing primary cutaneous diffuse large B-cell lymphoma, leg type. The primary endpoint was the 6-month overall response rate. Secondary endpoints were 12-month overall response rate, overall and specific survival, duration of response, progression-free survival, safety, and identification of prognostic factors. Among the 19 patients included, the 6-month overall response rate was 26.3% (90% confidence interval [CI] = 11-47.6), including four complete responses and one partial response. At 12 months, there were still two complete responses and one partial response. Median progression free survival was 4 months. Median overall and specific survivals were 19.4 and 23.8 months, respectively. Reduced doses tended to be associated with higher 6 month overall response rate and progression-free survival. Absence of the MYD88L265P mutation was associated with a higher overall response under treatment (80.0% vs. 33.3%; P = 0.05). The most common grade 3 adverse events were hematologic. Two grade 5 adverse events occurred (sepsis and pulmonary embolism). Lenalidomide at reduced doses may allow prolonged responses in a few patients and represents a therapeutic option in relapsing/refractory primary cutaneous diffuse large B-cell lymphoma, leg type. PMID- 29596905 TI - Rapamycin Modulates Glucocorticoid Receptor Function, Blocks Atrophogene REDD1, and Protects Skin from Steroid Atrophy. AB - Glucocorticoids have excellent therapeutic properties; however, they cause significant adverse atrophogenic effects. The mTORC1 inhibitor REDD1 has been recently identified as a key mediator of glucocorticoid-induced atrophy. We performed computational screening of a connectivity map database to identify putative REDD1 inhibitors. The top selected candidates included rapamycin, which was unexpected because it inhibits pro-proliferative mTOR signaling. Indeed, rapamycin inhibited REDD1 induction by glucocorticoids dexamethasone, clobetasol propionate, and fluocinolone acetonide in keratinocytes, lymphoid cells, and mouse skin. We also showed blunting of glucocorticoid-induced REDD1 induction by either catalytic inhibitor of mTORC1/2 (OSI-027) or genetic inhibition of mTORC1, highlighting role of mTOR in glucocorticoid receptor signaling. Moreover, rapamycin inhibited glucocorticoid receptor phosphorylation, nuclear translocation, and loading on glucocorticoid-responsive elements in REDD1 promoter. Using microarrays, we quantified a global effect of rapamycin on gene expression regulation by fluocinolone acetonide in human keratinocytes. Rapamycin inhibited activation of glucocorticoid receptor target genes yet enhanced the repression of pro-proliferative and proinflammatory genes. Remarkably, rapamycin protected skin against glucocorticoid-induced atrophy but had no effect on the glucocorticoid anti-inflammatory activity in different in vivo models, suggesting the clinical potential of combining rapamycin with glucocorticoids for the treatment of inflammatory diseases. PMID- 29596906 TI - Atrial electrogram quality in single-pass defibrillator leads with floating atrial bipole in patients with permanent atrial fibrillation and cardiac resynchronization therapy. AB - : Many patients receiving cardiac resynchronization therapy (CRT) suffer from permanent atrial fibrillation (AF). Knowledge of the atrial rhythm is important to direct pharmacological or interventional treatment as well as maintaining AV synchronous biventricular pacing if sinus rhythm can be restored. A single pass single-coil defibrillator lead with a floating atrial bipole has been shown to obtain reliable information about the atrial rhythm but has never been employed in a CRT-system. The purpose of this study was to assess the feasibility of implanting a single coil right ventricular ICD lead with a floating atrial bipole and the signal quality of atrial electrograms (AEGM) in CRT-defibrillator recipients with permanent AF. METHODS AND RESULTS: Seventeen patients (16 males, mean age 73 +/- 6 years, mean EF 25 +/- 5%) with permanent AF and an indication for CRT-defibrillator placement were implanted with a designated CRT-D system comprising a single pass defibrillator lead with a atrial floating bipole. They were followed-up for 103 +/- 22 days using remote monitoring for AEGM transmission. All patients had at last one AEGM suitable for atrial rhythm diagnosis and of 100 AEGM 99% were suitable for visual atrial rhythm assessment. Four patients were discharged in sinus rhythm and one reverted to AF during follow-up. CONCLUSION: Atrial electrograms retrieved from a single-pass defibrillator lead with a floating atrial bipole can be reliably used for atrial rhythm diagnosis in CRT recipients with permanent AF. Hence, a single pass ventricular defibrillator lead with a floating bipole can be considered in this population. PMID- 29596908 TI - The discrimination of magnitude: A review and theoretical analysis. AB - In a discrimination based on magnitude, the same stimulus is presented at two different magnitudes and an outcome, such as food, is signalled by one magnitude but not the other. The review presented in the first part of the article shows that, in general, such a discrimination is acquired more readily when the outcome is signalled by the larger rather than the smaller of the two magnitudes. This asymmetry is observed with magnitudes based on sound, odour, temporal duration, quantity, and physical length. The second part of the article, explores the implications of this pattern of results for the theory of discrimination learning presented by Pearce (1994). The asymmetry found with discriminations based on magnitude contradicts predictions derived from the original version of the theory, but it can be explained by a modified version. The asymmetry also has important implications for understanding how animals represent magnitudes. PMID- 29596907 TI - Urban-Rural Inequities in the Parental Attitudes and Beliefs Towards Human Papillomavirus Infection, Cervical Cancer, and Human Papillomavirus Vaccine in Mysore, India. AB - STUDY OBJECTIVE: The aim of this study was to compare the parental attitudes and beliefs about human papillomavirus (HPV), cervical cancer, and HPV vaccine between urban and rural areas, India. DESIGN: Cross-sectional. SETTING: Mysore, India. PARTICIPANTS: Parents of school-going adolescent girls. INTERVENTIONS: Parents completed a self-administered questionnaire. MAIN OUTCOME MEASURES: Attitudes and beliefs about HPV, cervical cancer, and HPV vaccine. RESULTS: A total of 1609 parents from urban (n = 778) and rural (n = 831) areas participated in this study. Most of the parents had never heard about HPV (73.6%), did not know that their daughters could get an HPV infection (62.7%) or cervical cancer (64.1%) in the future, and believed that HPV vaccine was not effective (67.1%). Parents living in the urban area were more likely to believe that HPV infection (adjusted odds ratio [aOR], 2.69; 95% confidence interval [CI], 1.43-5.06) and cervical cancer (aOR, 2.68; 95% CI, 1.83-3.91) could cause serious health problems than those living in the rural area. The odds of agreeing that HPV vaccination will make girls sexually active was lower among urban than rural parents (aOR, 0.55; 95% CI, 0.33-0.94). There was no significant difference among parents in the urban and rural areas in their beliefs about susceptibility of their daughter to HPV infection or cervical cancer, and beliefs about the safety and ability of HPV vaccine to protect against cervical cancer. CONCLUSION: Rural parents might be reluctant to recommend behaviors that can help prevent HPV infection and cervical cancer such as HPV vaccination for their daughters. PMID- 29596909 TI - Protein-nucleic acid interactions of LINE-1 ORF1p. AB - Long interspersed nuclear element 1 (LINE-1 or L1) is the dominant retrotransposon in mammalian genomes. L1 encodes two proteins ORF1p and ORF2p that are required for retrotransposition. ORF2p functions as the replicase. ORF1p is a coiled coil-mediated trimeric, high affinity RNA binding protein that packages its full- length coding transcript into an ORF2p-containing ribonucleoprotein (RNP) complex, the retrotransposition intermediate. ORF1p also is a nucleic acid chaperone that presumably facilitates the proposed nucleic acid remodeling steps involved in retrotransposition. Although detailed mechanistic understanding of ORF1p function in this process is lacking, recent studies showed that the rate at which ORF1p can form stable nucleic acid-bound oligomers in vitro is positively correlated with formation of an active L1 RNP as assayed in vivo using a cell culture-based retrotransposition assay. This rate was sensitive to minor amino acid changes in the coiled coil domain, which had no effect on nucleic acid chaperone activity. Additional studies linking the complex nucleic acid binding properties to the conformational changes of the protein are needed to understand how ORF1p facilitates retrotransposition. PMID- 29596910 TI - Intrinsic and Extrinsic Regulation of PD-L2 Expression in Oncogene-Driven Non Small Cell Lung Cancer. AB - INTRODUCTION: The interaction of programmed cell death ligand 2 (PD-L2) with programmed cell death 1 is implicated in tumor immune escape. The regulation of PD-L2 expression in tumor cells has remained unclear, however. We here examined intrinsic and extrinsic regulation of PD-L2 expression in NSCLC. METHODS: PD-L2 expression was evaluated by reverse transcription and real-time polymerase chain reaction analysis and by flow cytometry. RESULTS: BEAS-2B cells stably expressing an activated mutant form of EGFR or the echinoderm microtubule associated protein like 4 (EML4)-ALK receptor tyrosine kinase fusion oncoprotein manifested increased expression of PD-L2 at both the mRNA and protein levels. Furthermore, treatment of NSCLC cell lines that harbor such driver oncogenes with corresponding EGFR or ALK tyrosine kinase inhibitors or depletion of EGFR or ALK by small interfering RNA transfection suppressed expression of PD-L2, demonstrating that activating EGFR mutations or echinoderm microtubule associated protein like 4 gene (EML4)-ALK receptor tyrosine kinase gene (ALK) fusion intrinsically induce PD-L2 expression. We also found that interferon gamma (IFN gamma) extrinsically induced expression of PD-L2 through signal transducer and activator of transcription 1 signaling in NSCLC cells. Oncogene-driven expression of PD-L2 in NSCLC cells was inhibited by knockdown of the transcription factors signal transducer and activator of transcription 3 (STAT3) or c-FOS. IFN-gamma also activated STAT3 and c-FOS, suggesting that these proteins may also contribute to the extrinsic induction of PD-L2 expression. CONCLUSIONS: Expression of PD-L2 is induced intrinsically by activating EGFR mutations or EML4 ALK fusion and extrinsically by IFN-gamma, with STAT3 and c-FOS possibly contributing to both intrinsic and extrinsic pathways. Our results thus provide insight into the complexity of tumor immune escape in NSCLC.

PMID- 29596912 TI - Characterization of a large UNC13D gene duplication in a patient with familial hemophagocytic lymphohistiocytosis type 3. AB - Familial hemophagocytic lymphohistiocytosis (FHL) type 3 is a life-threatening immune dysregulation syndrome caused by mutations in the UNC13D gene, encoding the munc13-4 protein, which is important for function of cytotoxic lymphocytes. FHL3 accounts for 30-40% of FHL cases, and more than 100 mutations in the UNC13D gene have been described to date. We describe the first case of FHL3 carrying an intragenic duplication of UNC13D, apparently mediated by recombination of Alu elements. NK cell degranulation and munc13-4 protein expression assays are useful for early identification of such mutations, which may be missed by analysis of genomic DNA alone. PMID- 29596913 TI - Wing vein development in the sawfly Athalia rosae is regulated by spatial transcription of Dpp/BMP signaling components. AB - Wing venation among insects serves as an excellent model to address how diversified patterns are produced. Previous studies suggest that evolutionarily conserved Decapentaplegic (Dpp)/Bone Morphogenetic Protein (BMP) signal plays a critical role in wing vein development in the dipteran Drosophila melanogaster and the hymenopteran sawfly Athalia rosae. In sawfly, dpp is ubiquitously expressed in the wing during prepupal stages, but Dpp/BMP signal is localized in the future vein cells. Since localized BMP signaling involves BMP binding protein Crossveinless (Cv), redistribution of BMP ligands appears to be crucial for sawfly wing vein formation. However, how ubiquitously expressed ligands lead to a localized signal remains to be addressed. Here, we found that BMP binding protein short gastrulation (Sog) is highly expressed in the intervein cells. Our data also reveal that BMP type I receptors thickveins (Tkv) and saxophone (Sax) are highly expressed in intervein cells and at lower levels in the vein progenitor cells. RNAi knockdown of Ar-tkv or Ar-sax indicates that both receptors are required for localized BMP signaling in the wing vein progenitor cells. Taken together, our data suggest that spatial transcription of core- and co-factors of the BMP pathway sustain localized BMP signaling during sawfly wing vein development. PMID- 29596915 TI - Structural Ensemble Modulation upon Small-Molecule Binding to Disordered Proteins. AB - Over the past decade, there has been a growing interest in investigating whether disordered proteins can be targeted for clinical purposes using small molecules [1-8]. While small-molecule binding to disordered proteins can be seen as unorthodox, examples of this phenomenon have been reported. In order to rationalize these observations, a variety of models are emerging, sometimes in apparent contradiction. Here, we offer a "structural ensemble modulation" view as an attempt to clarify the language, organize concepts, and facilitate the comparison of different studies. In doing so, we hope to promote the understanding of the general principles underlying this phenomenon toward the development of novel therapeutic compounds targeting disordered proteins, which are prevalent in a wide range of human diseases [1-8]. PMID- 29596914 TI - VLR Recognition of TLR5 Expands the Molecular Characterization of Protein Antigen Binding by Non-Ig-based Antibodies. AB - Variable lymphocyte receptors (VLRs) are unconventional adaptive immune receptors relatively recently discovered in the phylogenetically ancient jawless vertebrates, lamprey and hagfish. VLRs bind antigens using a leucine-rich repeat fold and are the only known adaptive immune receptors that do not utilize an immunoglobulin fold for antigen recognition. While immunoglobulin antibodies have been studied extensively, there are comparatively few studies on antigen recognition by VLRs, particularly for protein antigens. Here we report isolation, functional and structural characterization of three VLRs that bind the protein toll-like receptor 5 (TLR5) from zebrafish. Two of the VLRs block binding of TLR5 to its cognate ligand flagellin in functional assays using reporter cells. Co crystal structures revealed that these VLRs bind to two different epitopes on TLR5, both of which include regions involved in flagellin binding. Our work here demonstrates that the lamprey adaptive immune system can be used to generate high affinity VLR clones that recognize different epitopes and differentially impact natural ligand binding to a protein antigen. PMID- 29596916 TI - Some Surprising Implications of NMR-directed Simulations of Substrate Recognition and Binding by Cytochrome P450cam (CYP101A1). AB - Cytochrome P450cam (CYP101A1) catalyzes the stereospecific 5-exo hydroxylation of d-camphor by molecular oxygen. Previously, residual dipolar couplings measured for backbone amide 1H-15N correlations in both substrate-free and bound forms of CYP101A1 were used as restraints in soft annealing molecular dynamic simulations in order to identify average conformations of the enzyme with and without substrate bound. Multiple substrate-dependent conformational changes remote from the enzyme active site were identified, and site-directed mutagenesis and activity assays confirmed the importance of these changes in substrate recognition. The current work makes use of perturbation response scanning (PRS) and umbrella sampling molecular dynamic of the residual dipolar coupling-derived CYP101A1 structures to probe the roles of remote structural features in enforcing the regio- and stereospecific nature of the hydroxylation reaction catalyzed by CYP101A1. An improper dihedral angle Psi was defined and used to maintain substrate orientation in the CYP101A1 active site, and it was observed that different values of Psi result in different PRS response maps. Umbrella sampling methods show that the free energy of the system is sensitive to Psi, and bound substrate forms an important mechanical link in the transmission of mechanical coupling through the enzyme structure. Finally, a qualitative approach to interpreting PRS maps in terms of the roles of secondary structural features is proposed. PMID- 29596917 TI - Clustering of unhealthy lifestyle behaviours and associations with perceived and actual weight status among primary school children in China: A nationally representative cross-sectional study. AB - Few studies have focused on clustering of unhealthy lifestyle behaviours among primary school children and potential associations with perceived and actual weight status. An index was constructed from adding up 13 unhealthy behaviours measured by survey responses. Multilevel linear regressions were used to analyse associations between child personal characteristics, perceived and actual weight status with the unhealthy lifestyle index among 11,157 children in primary schools across China. Parental and area factors were also taken into account, including education, weight status, physical activity, urban/rural and area socioeconomic circumstances. The unhealthy lifestyle index normally distributed, with 84.5% of children reporting between 2 and 6 unhealthy behaviours. Boys reported more unhealthy behaviours compared with girls (coefficient 0.32, 95%CI 0.26 to 0.37) and children in urban areas had fewer unhealthy behaviours than their rural counterparts (-0.29, 95%CI -0.56 to -0.03). An interaction revealed stronger 'protective' effects of living in cities for girls than boys, which were not explained by differences in child overweight/obesity. More unhealthy behaviours were characteristic of children in more affluent areas, and of those born to mothers and/or fathers with lower educational attainment. Children who perceived themselves as overweight or underweight both scored higher on the unhealthy lifestyle index. Unhealthy behaviours that could increase the risk of childhood obesity are common among Chinese primary school children, particularly among boys in cities, those in more affluent areas and with parents with lower education. There was no effect of actual weight status on number of unhealthy behaviours. Perceived, but not actual weight status, was also a significant correlate of unhealthy behaviours. Clustering of unhealthy lifestyle behaviours that could increase the risk of childhood obesity are common among Chinese primary school children, particularly among boys in cities, those in more affluent areas and with parents with lower education. Perceived, but not actual weight status, was also a significant correlate of unhealthy lifestyle. This has important implications for public health because understanding clustering of unhealthy lifestyle behaviours can be used to assist in the development of targeted obesity prevention initiatives. PMID- 29596918 TI - Association between exercise type and the decline in instrumental activities of daily living in community-dwelling older women: A 4-year prospective study. AB - Exercise can delay the decline of instrumental activities of daily living (IADL), although it remains unclear which specific exercise types are associated with such a delay. This 4-year prospective cohort study in Japan aimed to identify the longitudinal associations between exercise types and the onset of IADL decline in older women. Between 2008 and 2012, 1082 community-dwelling older women aged >=75 years participated in this study. Participations in 16 exercise types based on a face-to-face interview at baseline were used as independent variables. The primary study outcome was a decline in IADL as assessed using the instrumental self-maintenance subscale of the Tokyo Metropolitan Institute of Gerontology index of competence. An IADL decline was defined as a decrease of >=1 point over the 4-year follow-up period and was used as the dependent variable. Adjusted odds ratios (ORs) and 95% confident intervals (CIs) for IADL decline based on participation or non-participation in each exercise type were obtained using logistic regression analyses. An IADL decline was observed in 151 participants (13.9%) over the 4-year follow-up period. After adjustment for potential confounders, participation in calisthenics had a significantly lower OR (0.62; 95% CI 0.42-0.90) for IADL decline. There were no significant associations between other specific exercise types and IADL decline. In conclusion, participation in calisthenics was significantly and independently associated with delayed IADL decline in older women aged >=75 years. Thus, calisthenics may be a useful exercise to slow IADL decline in this age group. PMID- 29596919 TI - Reconstruction of radial bone defect in rat by calcium silicate biomaterials. AB - AIMS: Despite many attempts, an appropriate therapeutic method has not yet been found to enhance bone formation, mechanical strength and structural and functional performances of large bone defects. In the present study, the bone regenerative potential of calcium silicate (CS) biomaterials combined with chitosan (CH) as calcium silicate/chitosan (CSC) scaffold was investigated in a critical radial bone defect in a rat model. MAIN METHODS: The bioimplants were bilaterally implanted in the defects of 20 adult Sprague-Dawley rats. The rats were euthanized and the bone specimens were harvested at the 56th postoperative day. The healed radial bones were evaluated by three-dimensional CT, radiology, histomorphometric analysis, biomechanics, and scanning electron microscopy. KEY FINDINGS: The XRD analysis of the CS biomaterial showed its similarity to wollastonite (beta-SiCO3). The degradation rate of the CSC scaffold was much higher and it induced milder inflammatory reaction when compared to the CH alone. More bone formation and higher biomechanical performance were observed in the CSC treated group in comparison with the CH treated ones in histological, CT scan and biomechanical examinations. Scanning electron microscopic observation demonstrated the formation of more hydroxyapatite crystals in the defects treated with CSC. SIGNIFICANCE: This study showed that the CSC biomaterials could be used as proper biodegradable materials in the field of bone reconstruction and tissue engineering. PMID- 29596920 TI - The involvement of sympathetic nervous system in essence of chicken-facilitated physiological adaption and circadian resetting. AB - AIM: The impact of the sympathetic nervous system (SNS) on the regulation of circadian rhythm and physiological functions is still not clear. Previous studies have found that essence of chicken (EC) supplementation facilitated the physiological adaption and circadian resetting in rats subjected to jet lag. Herein, the effects of SNS on the circadian clock and the hypothesis that EC induced acceleration of circadian resetting is dependent on the SNS are investigated. MAIN METHODS: Male Wistar rats with superior cervical ganglionectomy (SCGx) were used to investigate the role of the SNS in circadian rhythm and physiological functions. SCGx rats were further fed with or without EC containing diet for 2 weeks and subjected to artificial jet lag. KEY FINDINGS: Loss of SNS did not affect the circadian rhythm both in the hypothalamic suprachiasmatic nuclei (SCN) and peripheral clocks, including the liver and heart. The serum lipid levels were increased significantly in SCGx rats, together with the up-regulation of lipogenic gene expression in the liver and slight effect on serum hormones. The quicker resetting process of the clock genes in peripheral tissues of EC-fed rats was abolished after SCGx. In contrast, the phase shift of serum melatonin and corticosterone were faster in EC-fed rats, compared to that of control rats. SIGNIFICANCE: The SNS controls different aspects of physiological functions, and it has little effect on circadian system under normal light/dark condition. The effects EC on peripheral circadian synchrony and physiological functions were dependent on, at least partly, through the regulation of sympathetic nerve function. PMID- 29596922 TI - Vitamin D and toll like receptors. AB - It has been demonstrated that vitamin D (VD) significantly modulates immune responses. Toll like receptors (TLRs) are the main innate immunity receptors which are expressed on the cell membrane and intracellular vesicles and recognize several pathogen associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs) to induce immune responses. Based on the important roles played by TLRs in physiologic and pathologic functions of immune responses and due to the immunomodulatory functions of VD, it has been hypothesized that VD may present its immunomodulatory functions via modulation of TLRs. This review article collates recent studies regarding the interactions between VD and TLRs and discussed the controversial investigations. PMID- 29596921 TI - N-(3-oxododecanoyl)-l-homoserine lactone modulates mitochondrial function and suppresses proliferation in intestinal goblet cells. AB - AIMS: The quorum-sensing molecule N-(3-oxododecanoyl)-l-homoserine lactone (C12 HSL), produced by the Gram negative human pathogenic bacterium Pseudomonas aeruginosa, modulates mammalian cell behavior. Our previous findings suggested that C12-HSL rapidly decreases viability and induces apoptosis in LS174T goblet cells. MAIN METHODS: In this study, the effects of 100 MUM C12-HSL on mitochondrial function and cell proliferation in LS174T cells treated for 4 h were evaluated by real-time PCR, enzyme-linked immunosorbent assay (ELISA) and flow cytometry. KEY FINDINGS: The results showed that the activities of mitochondrial respiratory chain complexes IV and V were significantly increased (P < 0.05) in LS174T cells after C12-HSL treatment, with elevated intracellular ATP generation (P < 0.05). Flow cytometry analysis revealed significantly increased intracellular Ca2+ levels (P < 0.05), as well as disrupted mitochondrial activity and cell cycle arrest upon C12-HSL treatment. Apoptosis and cell proliferation related genes showed markedly altered expression levels (P < 0.05) in LS174T cells after C12-HSL treatment. Moreover, the paraoxonase 2 (PON2) inhibitor TQ416 (1 MUM) remarkably reversed the above C12-HSL associated effects in LS174T cells. SIGNIFICANCE: These findings indicated that C12-HSL alters mitochondrial energy production and function, and inhibits cell proliferation in LS174T cells, with PON2 involvement. PMID- 29596923 TI - Effects of continuous bisphenol A exposure from early gestation on 90 day old rat testes function and sperm molecular profiles: A CLARITY-BPA consortium study. AB - Bisphenol A (BPA) is a ubiquitous industrial chemical that has been identified as an endocrine disrupting compound (EDC). There is growing concern that early life exposures to EDCs, such as BPA, can adversely affect the male reproductive tract and function. This study was conducted as part of the Consortium Linking Academic and Regulatory Insights on BPA Toxicity (CLARITY-BPA) to further delineate the toxicities associated with continuous exposure to BPA from early gestation, and to comprehensively examine the elicited effects on testes and sperm. NCTR Sprague Dawley rat dams were gavaged from gestational day (GD) 6 until parturition, and their pups were directly gavaged daily from postnatal day (PND) 1 to 90 with BPA (2.5, 25, 250, 2500, 25,000, 250,000 MUg/kg/d) or vehicle control. At PND 90, the testes and sperm were collected for evaluation. The testes were histologically evaluated for altered germ cell apoptosis, sperm production, and altered spermiation. RNA and DNA isolated from sperm were assessed for elicited changes in global mRNA transcript abundance and altered DNA methylation. Effects of BPA were observed in changes in body, testis and epididymis weights only at the highest administered dose of BPA of 250,000 MUg/kg/d. Genome-wide transcriptomic and epigenomic analyses failed to detect robust alterations in sperm mRNA and DNA methylation levels. These data indicate that prolonged exposure starting in utero to BPA over a wide range of levels has little, if any, impact on the testes and sperm molecular profiles of 90 day old rats as assessed by the histopathologic, morphometric, and molecular endpoints evaluated. PMID- 29596924 TI - Do in vitro assays in rat primary neurons predict drug-induced seizure liability in humans? AB - Drug-induced seizures contribute to the high attrition rate of pharmaceutical compounds in development. The assessment of drug-induced seizure liability generally occurs in later phases of development using low throughput and intensive in vivo assays. In the present study, we evaluated the potential of an in vitro assay for detecting drug-induced seizure risk compared to evaluation in rats in vivo. We investigated the effects of 8 reference drugs with a known seizurogenic risk using micro-electrode array (MEA) recordings from freshly dissociated rat primary neurons cultured on 48-well dishes for 28 days, compared to their effects on the EEG in anesthetized rats. In addition, we evaluated functional responses and mRNA expression levels of different receptors in vitro to understand the potential mechanisms of drug-induced seizure risk. Combining the functional MEA in vitro data with concomitant gene expression allowed us to identify several potential molecular targets that might explain the drug-induced seizures occurring in both rats and humans. Our data 1) demonstrate the utility of a group of MEA parameters for detecting potential drug-induced seizure risk in vitro; 2) suggest that an in vitro MEA assay with rat primary neurons may have advantages over an in vivo rat model; and 3) identify potential mechanisms for the discordance between rat assays and human seizure risk for certain seizurogenic drugs. PMID- 29596926 TI - Effects of prenatal exposure to triclosan on the liver transcriptome in chicken embryos. AB - Triclosan (TCS), a commonly used antimicrobial compound, has recently been detected in the eggs of wild avian species. Exposure to TCS in rodents is known to interfere with thyroid hormone (TH), disrupt immune responses and cause liver disease. However, no attempt has been made to clarify the effects of TCS in avian species. The aim of this study is therefore to evaluate the toxic effects of in ovo exposure to TCS and explore the molecular mechanism by transcriptome analysis in the embryonic liver of a model avian species, chicken (Gallus gallus). Embryos were treated with graded concentration of TCS (0.1, 1 and 10 MUg/g egg) at Hamburger Hamilton Stage (HHS) 1 (1st day), followed by 20 days of incubation to HHS 46. At the administration of 10 MUg TCS/g egg, embryo mortality increased from 20% in control to 37% accompanied with 8% attenuation in tarsus length. While liver somatic index (LSI) in TCS treatments was enhanced, statistical difference was only observed at the treatment of 0.1 MUg TCS/g egg in females. The up-regulation of several crucial differentially expressed genes (DEGs) in transcriptome analysis suggested that TCS induced xenobiotic metabolism (e.g. CYP2C23a, CYP2C45 and CYP3A37 in males; CYP2C45 in females) and activated the thyroid hormone receptor (THR) - mediated downstream signaling (e.g. THRSPB and DIO2 in males; THRSPB in females). In females, TCS may further activate the lipogenesis signaling (e.g. ACSL5, ELOVL2) and repress the lipolysis signaling (e.g. ABHD5, ACAT2). A battery of enriched transcription factors in relation to these TCS-induced signaling and phenotypes were found, including activated SREBF1, PPARa, LXRa, and LXRb in males and activated GLI2 in females; COUP-TFII was predicted to be suppressed in both genders. Finally, we developed adverse outcome pathways (AOPs) that provide insights into the molecular mechanisms underlying the alteration of phenotypes. PMID- 29596925 TI - Association of pesticide exposure with human congenital abnormalities. AB - Human pesticide exposure can occur both occupationally and environmentally during manufacture and after the application of indoor and outdoor pesticides, as well as through consumption via residues in food and water. There is evidence from experimental studies that numerous pesticides, either in isolation or in combination, act as endocrine disruptors, neurodevelopmental toxicants, immunotoxicants, and carcinogens. We reviewed the international literature on this subject for the years between 1990 and 2017. The studies were considered in this review through MEDLINE and WHO resources. Out of the n = 1817 studies identified, n = 94 were reviewed because they fulfilled criteria of validity and addressed associations of interest. Epidemiological studies have provided limited evidence linking pre- and post-natal exposure to pesticides with cancers in childhood, neurological deficits, fetal death, intrauterine growth restriction, preterm birth, and congenital abnormalities (CAs). In this review, the potential association between pesticide exposure and the appearance of some human CAs (including among others musculoskeletal abnormalities; neural tube defects; urogenital and cardiovascular abnormalities) was investigated. A trend towards a positive association between environmental or occupational exposure to some pesticides and some CAs was detected, but this association remains to be substantiated. Main limitations of the review include inadequate exposure assessment and limited sample size. Adequately powered studies with precise exposure assessments such as biomonitoring, are warranted to clarify with certainty the potential association between pesticide exposure and human CAs.

PMID- 29596928 TI - Cardiac safety evaluation in zebrafish and in silico ADME prediction of cephalosporins with an aminothiazoyl ring at the C-7 position. AB - Systems toxicology approaches have been used as important tools in the drug discovery and medicine quality control processes. The aim of this study was to assess the pharmacokinetic and toxicity properties of cephalosporins with an aminothiazoyl ring at the C-7 position (CATRs). Cardiac toxicity of the compounds was assessed in zebrafish embryos, and it was determined that CATRs disturbed the formation and development of the heart in a dose-dependent manner. Differentially expressed genes (DEGs) related to the heart were also identified by transcriptome analysis, and co-DEGs were obtained in the protein-protein interaction (PPI) network. Several Gene Ontology (GO) terms and pathways that were enriched by DEGs were identified, and the most significantly enriched pathways were adrenergic signaling in cardiomyocytes, cardiac muscle contraction, and vascular smooth muscle contraction. Combined molecular docking results elucidated that cardiac toxicity mainly depends on the mother nucleus structure 7-aminocephalosporanic acid (7-ACA). The predicted absorption, distribution, metabolism and excretion (ADME) profile suggests that there is a modification at the C-3 side chain of 7 ACA that could change the compound distribution in vivo. The 7-ACA mother nucleus is responsible for the CATRs induced cardiac toxicity, and the three DEGs (nppa, adra2c, and tnni1c) may potentially be utilized as novel biomarkers for CATRs. Our results show that zebrafish embryos may be used to reveal the pathways of cardiac toxicity and they play a vital role in drug safety assessments. PMID- 29596929 TI - Preparation, characterization, and biodegradation of poly(butylene succinate)/cellulose triacetate blends. AB - Poly(butylene succinate) (PBS) and cellulose triacetate (CT) were blended using chloroform as solvent. The solid-state properties of PBS/CT blends were confirmed by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), thermogravimetric analysis, scanning electron microscopy (SEM), and water contact angle measurements. FTIR results show that PBS and CT were physically blended. Tensile strength was not distinguished when the weight percent of CT was <15%, and Young's modulus increased gradually with increasing CT. DSC and XRD results show that the crystals were homogeneous, and crystallinity had no apparent decrease when <10% CT was added to the PBS matrix. However, the addition of more CT components could destroy the crystal behavior of PBS. SEM showed that no phase separation occurred between the two materials. The addition of CT increased the hydrophilicity of PBS/CT1-15 blends. The weight loss was nearly 90% after 16h of degradation for PBS/CT10. The appropriate proportion of PBS to CT was 90:10. PMID- 29596930 TI - Evaluation of nitriloacetic acid modified cellulose film on adsorption of methylene blue. AB - A novel composite film (MCalphaN) based on microcrystalline cellulose (MCC) and nitrilotriacetic acid anhydride (NTAA) was prepared via casting method for the adsorption of methylene blue (MB) from aqueous solution. FT-IR, XRD, elemental analysis and TGA analysis demonstrated the success of modification. The swelling behavior, mechanical properties and MB adsorption performance of the modified MCalphaN films were improved obviously. The recycling study illustrated that MC2N film could be recycled and exhibited constant adsorption performance for five successful runs. In addition, mechanism study found that adsorption behavior of the composite films was better consistent with the pseudo-second order kinetic model and the Langmuir model. All the results suggested that the MCalphaN films could be considered as a promising candidate for dye wastewater treatment. PMID- 29596931 TI - Fabrication and characterization of electrospun nanofibers using flaxseed (Linum usitatissimum) mucilage. AB - The spin ability of flaxseed mucilage (FM) as a new source was evaluated through electrospinning. At various experimental conditions and different solution properties, it was impossible to fabricate FM nanofiber. Thus, polyvinyl alcohol (PVA) was applied as co-polymer to facilitate nanofiber formation. In terms of morphology, FM:polyvinyl alcohol (PVA) nanofiber using a mixture of 3% FM solution and 12% (PVA) solution at ratio of 60:40 was selected as the best sample. The physicochemical properties of the nanofiber was evaluated by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD). SEM images showed beadless, uniform and smooth nanofibers with an average diameter of 230nm. Based on DSC and TGA results, the thermal stability of the nanofiber was improved by adding PVA. FTIR data revealed that there was no chemical interaction between functional groups of FM and PVA in the nanofiber. PMID- 29596932 TI - Extraction, characterisation and antioxidant activity of Allium sativum polysaccharide. AB - Extraction and antioxidant activity of polysaccharide from Allium sativum were investigated. The crude polysaccharide was obtained by the hot-water extraction method. The molecular weight of polysaccharide deproteinized with CaCl2 was 7.35*103. It indicated that polysaccharide from Allium sativum consisted of three monosaccharides, namely fructose, glucose, and galactose by HPLC. The polysaccharide had the beta-glycosidic bond. Moreover, it was proved that the polysaccharide had the potential scavenging ability to superoxide anions and hydroxyl radicals. So, it should be a potential antioxidant. PMID- 29596933 TI - Identification, purification, biochemical and mass spectrometric characterization of novel phycobiliproteins from a marine red alga, Centroceras clavulatum. AB - Phycobilisomes are light-harvesting protein complexes and are widely distributed in red algae and cyanobacteria. Each phycobilisome contains highly fluorescent protein components called phycobiliproteins. Based upon the distinct physiochemical properties, phycobiliproteins are classified as allophycocyanin, phycocyanin, phycoerythrin and phycoerythrocyanin. In the present study, we describe purification and structural characterization of a novel phycocyanin and phycoerythrin isolated from a marine red macroalga, Centroceras clavulatum. The absorbance and fluorescence studies indicated that the purified proteins belong to R-Phycocyanin (R-PC) and R-Phycoerythrin (R-PE). The single bands under native polyacrylamide gel electrophoresis revealed the intact molecular weights of R-PC and R-PE as 110kDa and 250kDa. The polypeptide compositions of the two proteins were demonstrated by SDS-PAGE. The result showed that R-PC contains two bands at 17 and 21kDa and were identified as alpha and beta subunits through mass spectrometry based proteomics experiments. SDS-PAGE of R-PE showed three distinct bands at 18, 19 and 35kDa and was subsequently identified as alpha, beta and gamma subunits. The near-complete amino acid sequences of alpha and beta subunits of R-PC and R-PE were derived from mass spectrometric data combined with Mascot software and multiple de novo sequencing tools followed by homology search and manual validation. PMID- 29596934 TI - A non-woven fabric wound dressing containing layer - by - layer deposited hyaluronic acid and chitosan. AB - Novel wound dressings composed of non-woven cotton (NWC) fabric and multilayer of hyaluronan (HA) and chitosan were built using layer-by-layer assembly technique. Factors affecting the building up of that dressings such as HA concentration, number of coating layers and nitrogen content of the NWC fabric quaternized form were studied. Meanwhile, some physico-chemical properties of such dressings were investigated. Moreover, to enhance the antibacterial properties of the aforementioned dressings, Silver nano-particles (Ag NPs) were prepared and incorporated as a functional additive in the final HA layer of such dressings. Factors affecting the building up of that dressings such as HA concentration, number of coating layers and nitrogen content of the NWC fabric quaternized form were studied. The results obtained showed that: i) increasing of HA concentration from 0.25 to 1.0% is accompanied by a gradual reduction in the swelling properties and an improvement in the gel fractionas as well as antibacterial properties of treated fabric along with a decreasing in extents of stiffness, air permeability and the relative water vapor permeability of treated fabric, ii) increasing of steeping time of coated samples results in an improvement in percent swelling of these samples. TEM image of the prepared Ag-NPs depicts that the particle size of that nano-particles was <13nm. Furthermore, the prepared dressing surface was characterized via scanning electron microscope. The EDX of Ag NPs loaded dressings confirmed the presence of Ag NPs onto such dressings with Ag - content of 0.24% (w/w). The thermogravimetric analysis assured that the prepared dressings based on quaternized NWC fabric have higher thermal stability than the un-quaternized form. PMID- 29596935 TI - Inhibition of amyloid fibril formation of lysozyme by ascorbic acid and a probable mechanism of action. AB - Amyloid fibrillation of proteins and polypeptides and their deposition in cells and tissues is associated with a number of pathological states collectively known as amyloid disorders. Inhibition of protein misfolding and aggregation is thus of utmost importance in the prevention and treatment of such diseases. There is a growing interest in identification of small molecules that can bind to native monomeric proteins or their partially unfolded states, thereby stabilizing them and preventing or delaying them from undergoing amyloid fibril formation. Here we report the inhibitory effect of ascorbic acid, an essential dietary component richly present in many natural food items, on the amyloid fibrillation of hen egg white lysozyme, a model protein for amyloid formation. The effect was dose dependent with more than 80% inhibition occurring even at only a five-fold molar excess of ascorbic acid. TEM images show complete absence of fibrils in the presence of ascorbic acid. From our spectroscopic and computational characterization of ascorbic acid binding to HEWL, we propose that ascorbic acid binds to the aggregation prone beta domain of HEWL, stabilizes the partially unfolded conformation and prevents further conformational changes leading to fibrillation. Hence ascorbic acid has a great therapeutic potential for amyloid disorders. PMID- 29596936 TI - Tuning lysozyme nanofibers dimensions using deep eutectic solvents for improved reinforcement ability. AB - Deep eutectic solvents (DESs), a novel generation of solvents, have recently been described as efficient and timesaving fibrillation agents for proteins. In this context, the present work aims at assessing the effect of the hydrogen bond donor (HBD) of cholinium chloride ([Ch]Cl):carboxylic acid based DESs on the dimensions (length and width) of lysozyme nanofibers (LNFs). Mono-, di- and tri-carboxylic acids (acetic, lactic, levulinic, malic and citric acids) were used to prepare different DES formulations, which were successfully used on the fibrillation of lysozyme. The results showed that the carboxylic acid (i.e. the HBD) plays an important role on the fibrillation efficiency and on the length of the ensuing LNFs with aspect-ratios always higher than those obtained by fibrillation with [Ch]Cl. The longest LNFs were obtained using lactic acid as the HBD with an average length of 1004 +/- 334 nm and width of 31.8 +/- 6.8 nm, and thus an aspect-ratio of ca. 32. The potential of these protein nanofibers as reinforcing additives was evaluated by preparing pullulan (PL)-based nanocomposite films containing 5% LNFs with different aspect-ratios, resulting in highly homogenous and transparent films with improved mechanical performance. PMID- 29596937 TI - Insights into the molecular interaction between sucrose and alpha-chymotrypsin. AB - One of the most important purposes of enzyme engineering is to increase the thermal and kinetic stability of enzymes, which is an important factor for using enzymes in industry. The purpose of the present study is to achieve a higher thermal stability of alpha-chymotrypsin (alpha-Chy) by modification of the solvent environment. The influence of sucrose was investigated using thermal denaturation analysis, fluorescence spectroscopy, circular dichroism, molecular docking and molecular dynamics (MD) simulations. The results point to the effect of sucrose in enhancing the alpha-Chy stability. Fluorescence spectroscopy revealed one binding site that is dominated by static quenching. Molecular docking and MD simulation results indicate that hydrogen bonding and van der Waals forces play a major role in stabilizing the complex. Tm of this complex was enhanced due to the higher H-bond formation and the lower surface hydrophobicity after sucrose modification. The results show the ability of sucrose in protecting the native structural conformation of alpha-Chy. Sucrose was preferentially excluded from the surface of alpha-Chy which is explained by the higher tendency of water toward favorable interactions with the functional groups of alpha-Chy than with sucrose. PMID- 29596938 TI - Blockade of TNF receptor superfamily 1 (TNFR1)-dependent and TNFR1-independent cell death is crucial for normal epidermal differentiation. AB - BACKGROUND: A delicate balance between cell death and keratinocyte proliferation is crucial for normal skin development. Previous studies have reported that cellular FLICE (FADD-like ICE)-inhibitory protein plays a crucial role in prevention of keratinocytes from TNF-alpha-dependent apoptosis and blocking of dermatitis. However, a role for cellular FLICE-inhibitory protein in TNF-alpha independent cell death remains unclear. OBJECTIVE: We investigated contribution of TNF-alpha-dependent and TNF-alpha-independent signals to the development of dermatitis in epidermis-specific Cflar-deficient (CflarE-KO) mice. METHODS: We examined the histology and expression of epidermal differentiation markers and inflammatory cytokines in the skin of CflarE-KO;Tnfrsf1a+/- and CflarE KO;Tnfrsf1a-/- mice. Mice were treated with neutralizing antibodies against Fas ligand and TNF-related apoptosis-inducing ligand to block TNF-alpha-independent cell death of CflarE-KO;Tnfrsf1a-/- mice. RESULTS: CflarE-KO;Tnfrsf1a-/- mice were born but experienced severe dermatitis and succumbed soon after birth. CflarE-KO;Tnfrsf1a+/- mice exhibited embryonic lethality caused by massive keratinocyte apoptosis. Although keratinocytes from CflarE-KO;Tnfrsf1a-/- mice still died of apoptosis, neutralizing antibodies against Fas ligand and TNF related apoptosis-inducing ligand substantially prolonged survival of CflarE KO;Tnfrsf1a-/- mice. Expression of inflammatory cytokines, such as Il6 and Il17a was increased; conversely, expression of epidermal differentiation markers was severely downregulated in the skin of CflarE-KO;Tnfrsf1a-/- mice. Treatment of primary keratinocytes with IL-6 and, to a lesser extent, IL-17A suppressed expression of epidermal differentiation markers. CONCLUSION: TNF receptor superfamily 1 (TNFR1)-dependent or TNFR1-independent apoptosis of keratinocytes promotes inflammatory cytokine production, which subsequently blocks epidermal differentiation. Thus blockade of both TNFR1-dependent and TNFR1-independent cell death might be an alternative strategy to treat skin diseases when treatment with anti-TNF-alpha antibody alone is not sufficient. PMID- 29596939 TI - Immune checkpoint blockade therapy. AB - Immune checkpoints are accessory molecules that either promote or inhibit T-cell activation. Two inhibitory molecules, cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1), got high attention, as inhibition of CTLA-4 or PD-1 signaling provides the first immune therapy that significantly improves the survival of patients with metastatic solid cancers. Inhibition of CTLA-4 or PD-1 was first studied in and approved for patients with metastatic melanoma. Blocking immune checkpoints is also efficient in non-small-cell lung cancer, renal cell cancers, hypermutated gastrointestinal cancers, and others. Immune responses, whether directed against infections or against tumors, are divided into 2 phases: an initiation phase and an activation phase, where the immune system recognizes a danger signal and becomes activated by innate signals to fight the danger. This reaction is fundamental for the control of infections and cancer, but needs to be turned off once the danger is controlled, because persistence of this activation ultimately causes severe tissue damage. Therefore, each activation of the immune system is followed by a termination phase, where endogenous immune suppressor molecules arrest immune responses to prevent harmful damage. In the case of cancer immune therapies, therapeutic approaches classically enhanced the initiation and activation of immune responses to increase the emergence and the efficacy of cytotoxic T lymphocytes (CTL) against cancers. In sharp contrast, immune checkpoint blockade focuses on the termination of immune responses by inhibiting immune suppressor molecules. It thus prevents the termination of immune responses or even awakes those CTLs that became exhausted during an immune response. Therefore, blocking negatively regulating immune checkpoints restores the capacity of exhausted CTL to kill the cancer they infiltrate. In addition, they drive surviving cancer cells into a still poorly defined state of dormancy. As the therapy also awakes self-reactive CTL, one downside of the therapy is the induction of organ-specific autoimmune diseases. The second downside is the exorbitant drug price that withdraws patients in need from a therapy that was developed by academic research, which impairs further academic treatment development and financially charges the public health system. PMID- 29596940 TI - Long-term outcomes associated with triple-goal achievement in patients with type 2 diabetes mellitus (T2DM). AB - AIMS: This study was designed to compare the risk of long-term health outcomes, including microvascular, macrovascular complications and mortality, across 4 cohorts: triple-goal, dual-goal, single-goal, and no-goal achievers. METHODS: A retrospective cohort of 53,120 patients with T2DM were identified (97.51% male, 61.49% whites) from the Veterans Affairs (VA) electronic medical records VISN 16 data warehouse (2004-2010). Propensity score weight (PSW) was used to balance demographic characteristics and complication history at baseline. The PSW adjusted hazard ratios (aHR) from Cox proportional hazard models were used to compare complications and all-cause mortality over an average of 4 years of follow-up. RESULTS: At baseline, 25.43% (13,507) patients achieved triple-goal, while 41.36% (21,972) and 26.37% (14,010) patients achieved dual-goal and single goal, respectively. During the follow-up period, triple-goal achievement was associated with risk reductions of complications and all-cause mortality when compared to all other groups of achieving dual or single-goal. Across different combinations of dual-goal achievement, the cohort with LDL-C goal achievement had lower risk of complication events and mortality, compared to those that achieved other goals but failed to reach LDL-C goal. CONCLUSIONS: Achievement of triple goal was associated with better health outcomes among veterans with T2DM compared to those that did not, while LDL-C has more weight of influence. Multi-faceted treatment strategies targeting hypertension, hyperglycemia and hyperlipidemia may improve health outcome in veterans with T2DM. PMID- 29596941 TI - Prevalence of type 2 diabetes and prediabetes in the Faroe Islands. AB - AIMS: To determine the prevalence of type 2 diabetes mellitus and prediabetes among the population aged 40-74 years in the Faroe Islands. METHODS: This population-based cross-sectional survey, conducted between 2011 and 2012, invited 2186 randomly selected individuals (corresponding to 11.1% of the entire population aged 40-74 years). Subjects were screened using finger capillary blood for glycosylated hemoglobin, type A1c, non-fasting random plasma glucose, fasting plasma glucose followed by oral glucose tolerance test. The test was based on an algorithm that accounts for screening, diagnostic and confirmatory steps. Anthropometric measures and a questionnaire including medical history, medication, hereditary conditions, and food intake were included. RESULTS: The study included 1772 participants. Of the 1772, 169 (9.5%) had type 2 diabetes mellitus (3.0% of which were diagnosed upon study inclusion), thus 31.4% of subjects with diabetes were undiagnosed at the time of examination. A total of 271 (15.3%) had prediabetes. Diabetes was more prevalent among men, significantly from age >=60 years. Women had lower mean fasting plasma glucose concentrations and men had lower values for 2-h plasma glucose. Predictors associated with diabetes mellitus included obesity (BMI >= 30), abnormal waist/hip ratio, history of hypertension or cardiovascular attack and family history of diabetes mellitus and leisure activity. CONCLUSIONS: The prevalences of diabetes and prediabetes increased with age and were more frequent among men. The detected prevalence in the Faroe Islands was slightly higher than other Nordic countries. PMID- 29596942 TI - Diabetes in the Bedouin population in the Israeli Negev - An update 2017. AB - AIMS: The Bedouins are an Arab population living in Israel severely impacted by diabetes and obesity. The aim of this research was to update the prevalence of diabetes among Bedouins in the Negev and to observe differences in this population in comparison with non-Bedouins in Israel. METHODS: A cross-sectional study was performed using the Clalit Health Services database. Diabetes prevalence among Bedouins was compared with non-Arabs and non-Bedouin Arabs in Israel. Differences in sexes and among Bedouins living in planned cities and unrecognized villages were observed. RESULTS: The age-adjusted prevalence of diabetes was 12.3% in the Bedouin population versus 8.2% in the non-Arab population in southern Israel (p < 0.0001). Diabetes prevalence among Bedouins and all Arabs in Israel was similar (12.0%). In all of Israel, age-adjusted diabetes prevalence was 8.8% for men and 7.5% in women (p < 0.0001) compared to 12.0% for men and 12.5% for women in the Bedouin population (p = 0.0008). In the Bedouin population in planned cities, age-adjusted diabetes prevalence was 12.5% versus 10.5% in the Bedouin population in unrecognized villages (p < 0.0001). CONCLUSIONS: This study shows that the prevalence of diabetes among Bedouins is higher than non-Bedouins in Israel. Increasing urbanization of the Bedouin population with their higher diabetes prevalence indicates the need for increased medical intervention as well as continuing investigation into the causes. PMID- 29596943 TI - The Berlin Declaration: A call to action to improve early actions related to type 2 diabetes. How can specialist care help? AB - Diabetes is a major global epidemic and places a huge burden on healthcare systems worldwide. The complications of type 2 diabetes (T2D) and related hospitalizations are major contributors to this burden, and there is strong evidence that the risk for these can be reduced by early action to identify and prevent progression of people at high risk of T2D and ensure tight glycemic control in those with established disease. In response to this, the Berlin Declaration was developed by four working groups of experts and ratified by healthcare professionals from 38 countries. Its aim is to act as a global call to action for early intervention in diabetes, in addition to providing short-, medium- and long-term targets that should be relevant to all nations. The Berlin Declaration focuses on four aspects of early action, and proposes actionable policies relating to each aspect: early detection, prevention, early control and early access to the right interventions. In addition, a number of treatment targets are proposed to provide goals for these policies. To ensure that the suggested policies are enacted in the most effective manner, the support of specialist care professionals is considered essential. PMID- 29596944 TI - Postpartum risk of diabetes and predictive factors for glucose intolerance in East Asian women with gestational diabetes. AB - AIMS: Women with a history of gestational diabetes mellitus (GDM) are likely to develop postpartum diabetes mellitus (DM). We examined women in the early stages of pregnancy who were at high risk of postpartum DM progression to establish a follow-up method for early detection. METHODS: We performed the oral glucose tolerance test (OGTT) and identified predictive factors for postpartum impaired glucose tolerance (IGT) or DM in 77 women after GDM, for 2 years after delivery, retrospectively. Cutoff values for each factor were determined. We classified these women with GDM into four groups using these predictive factors and evaluated postpartum glucose intolerance (GI) in each group. RESULTS: In total, 44.1% of the women with a GDM history had developed postpartum GI within 2 years. We determined three risk factors for postpartum GI: elevated glucose level 120 min after a 75-g OGTT (Glu120), elevated glycated hemoglobin (HbA1c) level at diagnosis, and perinatal complications. The cutoff Glu120 and the HbA1c level were 155 mg/dl and 5.3% (34 mmol/mol), respectively. Type 2 DM developed in 53.8% of women, and IGT developed in 38.5% of women within 2 years in groups with high Glu120 and high HbA1c. CONCLUSIONS: High-risk groups require careful follow-up observation. PMID- 29596945 TI - Association between diabetic peripheral neuropathy and heart rate variability in subjects with type 2 diabetes. AB - AIM: This study evaluated the association of Heart rate variability (HRV) measurements with diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes. METHODS: This study included 102 Korean subjects with type 2 diabetes. The Michigan neuropathy screening instrument (MNSI) questionnaire score, the MNSI examination score (MNSIES) and the total symptom score were examined for DPN evaluation. Noninvasive HRV measurements were performed using photoelectric plethysmography. Patients with a MNSIES > 2 were considered to have DPN. RESULTS: The MNSIES showed significant negative associations with the high frequency (HF) (r = -0.212, p = 0.033) and low frequency (LF) (r = -0.286, p = 0.004) powers. Multiple linear regression analysis revealed that only HF power maintained a significant negative association with the MNSIES (beta = -0.184; 95% CI -0.365 to -0.003; p = 0.047), after controlling for significant related confounders, with HRV parameters in male patients with type 2 diabetes. The HF (p = 0.010) and LF (p = 0.025) powers differed significantly between male patients without and those with DPN according to the MNSIES. CONCLUSIONS: This study revealed a negative association of DPN, as assessed by the MNSIES, with HF power in male patients with type 2 diabetes. DPN defined by foot examination was predictive of cardiac autonomic neuropathy. PMID- 29596946 TI - Genome-wide DNA methylation profiling in infants born to gestational diabetes mellitus. AB - BACKGROUND: Offspring exposed to gestational diabetes mellitus (GDM) are at a high risk for metabolic diseases. The mechanisms behind the association between offspring exposed to GDM in utero and an increased risk of health consequences later in life remain unclear. The aim of this study was to clarify the changes in methylation levels in the foetuses of women with GDM and to explore the possible mechanisms linking maternal GDM with a high risk of metabolic diseases in offspring later in life. METHODS: A genome-wide comparative methylome analysis on the umbilical cord blood of infants born to 30 women with GDM and 33 women with normal pregnancy was performed using Infinium HumanMethylation 450 BeadChip assays. A quantitative methylation analysis of 18 CpG dinucleotides was verified in the validation umbilical cord blood samples from 102 newborns exposed to GDM and 103 newborns who experienced normal pregnancy by MassARRAY EpiTYPER. RESULTS: A total of 4485 differentially methylated sites (DMSs), including 2150 hypermethylated sites and 2335 hypomethylated sites, with a mean beta-value difference of >0.05, were identified by the 450k array. Good agreement was observed between the massarray validation data and the 450k array data (R2 > 0.99; P < 0.0001). Thirty-seven CpGs (representing 20 genes) with a beta-value difference of > 0.15 between the GDM and healthy groups were identified and showed potential as clinical biomarkers for GDM. "hsa04940: Type I diabetes mellitus" was the most significant Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, with a P-value = 3.20E-07 and 1.36E-02 in the hypermethylated and hypomethylated genepathway enrichment analyses, respectively. In the Gene Ontology (GO) pathway analyses, immune MHC (major histocompatibility complex) related pathways and neuron development-related pathways were significantly enriched. CONCLUSIONS: Our results suggest that GDM has epigenetic effects on genes that are preferentially involved in the Type I diabetes mellitus pathway, immune MHC-related pathways and neuron development-related pathways, with consequences on fetal growth and development, and provide supportive evidence that DNA methylation is involved in fetal metabolic programming. PMID- 29596947 TI - FIGO analysis of research priorities in hyperglycemia in pregnancy. AB - Hyperglycemia in pregnancy (HIP) is recognized as a major underlying cause of pregnancy complications and a contributing cause to health risks throughout the subsequent life of both mothers and babies, with amplification of the global epidemic of non-communicable diseases. Although some aspects of these associations are well described, detailed understanding of basic pathophysiologic mechanisms is lacking. Improved fundamental scientific knowledge must be developed to allow logical strategies for prevention and treatment. During pregnancy, much work is required to replace current empirical approaches to diagnosis and treatment of HIP with evidence based protocols, pragmatically adapted to differing health care and health economic contexts. Further, a life cycle approach to HIP, the risk of immediate pregnancy complications and later health risks to mother and baby must be developed and implemented across a wide range of health care environments. This document aims to outline key focus areas for further basic, epidemiologic, clinical and implementation research in this important area. PMID- 29596948 TI - What is the best strategy on detection of cornea neuropathy in people with diabetes? Recent advances in potential measurements. AB - There are well-acknowledged clinical or pre-clinical measurements concerning diabetic peripheral neuropathy (DPN). The current gold standard for diagnosis of diabetic peripheral neuropathy is nerve conduction suitable for detecting large nerve fiber function and intraepidermal nerve fiber density assessment for small fiber damage evaluation [2]. The lack of a sensitive, non-invasive, and repeatable endpoint to measure changes in small nerve fibers is a major factor holding back clinical trials for the treatment of diabetic peripheral neuropathy. As cornea is the most densely innerved tissue, assessing corneal nerves' structure and function will be promising to predict and assess the degree of DPN. In the diabetic micro-environment, damaged corneal nerves lead to decreased corneal sensitivity, both of which resulting in abnormal tear function. According to this theory, the measurements of nerve structure, corneal sensitivity, tear secretion and tear components, to some extent, can reveal and assess the state of corneal neuropathy. This review focuses on summarizing the knowledge of the latest detective methods of diabetic corneal neuropathy, popular in use or possible to further in study and be applied into clinical practice. PMID- 29596949 TI - Epidemiological dimensions of the association between type 2 diabetes and cancer: A review of observational studies. AB - Type 2 diabetes (T2D) is a major cause of complications and death in many countries. The possible causal relation between T2D and cancer has been the aim of many research investigations. In view of the importance of the topic we carried out a narrative review of observational studies to summarize the available evidence of the association between T2D and cancer. To deal with the problem of abundance of published studies, we reviewed up to December 2017, the literature of meta-analyses of observational studies first, then we reviewed cohort studies not reported in meta-analyses because of more recent publication. We found that the association of T2D with risk of colorectal cancer was robust, whereas the evidence of the associations with other cancer sites was lower. Some of the observed associations could be overestimated, due to publication bias, unmeasured confounders (such as obesity) and surveillance bias. In conclusion a probable causal association of T2D with risk of colorectal cancer was confirmed. A possible causal association with pancreatic, endometrial, hepatocellular and gallbladder carcinoma was also found. Substantial uncertainty exists for other cancer sites. PMID- 29596950 TI - One-year effects of a group-based lifestyle intervention in adults with type 2 diabetes: A randomized encouragement trial. AB - AIMS: To estimate the real-world effects of offering a group-based lifestyle intervention (GLI) to adults with diabetes. METHODS: This randomized encouragement trial included adult primary care patients in metropolitan Chicago with type 2 diabetes and body mass index >=24 kg/m2. Participants were randomized to standard care (brief dietary and lifestyle counseling) or standard care plus being encouraged, but not required, to participate in a free-of-charge GLI offered by the YMCA. The GLI was a group-based adaptation of the Look AHEAD lifestyle intervention. RESULTS: Of 331 participants, 167 were randomized to standard care and 164 to the GLI encouragement arm. About one third of participants were non-Hispanic White (34.4%). In the GLI arm, 75 (45.7%) attended >=1 GLI visits. In the primary intention-to-treat analysis, the effect of GLI encouragement was 0.95% weight loss at six months (95% confidence interval [CI], 0.13-1.77%; P = 0.02), and 1.20% weight loss at 12 months (95% CI, 0.05-2.36%; P = 0.04). At 12 months, there was a 0.30% (3.3 mmol/mol) reduction in hemoglobin A1c, but this result did not achieve statistical significance (P = 0.054). In instrumental variable analysis estimating effects among the subgroup of participants who attended any GLI visits, the effect of GLI attendance was 2.30% weight loss at six months (95% CI, 0.30-4.30%; P = 0.02), and 2.07% weight loss at 12 months (95% CI, 0.25-3.88%; P = 0.02). We detected no significant blood pressure or cholesterol effects. CONCLUSIONS: Among adults with type 2 diabetes, a group-based lifestyle intervention in a community-based setting achieved modest weight loss at 6 and 12 months.

PMID- 29596952 TI - Diabetologists and Oncologists attitudes towards treating diabetes in the oncologic patient: Insights from an exploratory survey. AB - AIMS: Diabetes and cancer frequently coexist in the same subject, often having relevant effects on the management and prognosis of the oncologic patient. However, existing guidelines do not deal with many clinical issues in this setting appropriately. In evaluating the opinions of Diabetologists and Oncologists dealing with diabetes care in people with cancer, the Italian Association of Diabetologists (AMD) promoted a dedicated exploratory survey. METHODS: The survey was carried out through the web or handily delivered printed copies between October 2014 and April 2015, in Italy. It was composed of 27 questions intended to gather information on the characteristics of participants and to examine their clinical habits in this context, and participation was totally free and anonymous. RESULTS: A total of 252 physicians participated in the survey. Diabetologists accounted for 51.1% of respondents. According to survey results, in spite of the presence of diabetes (or diabetic complications) worsening the outcome of cancer treatments, the counseling or intervention of a Diabetologist was only required for less than two-thirds of hospitalized patients. For subjects with a life expectancy of months, 80% of specialists considered a glycemic target of 120-250 mg/dL optimal whereas Oncologists were more likely to consider a range of 180-360 mg/dL for patients with a shorter life expectancy. Furthermore, 1 participant out of 3 indicated 1-4 measurements/day as the most appropriate frequency for blood glucose monitoring including in the palliative setting. Insulin was the therapy of choice for the majority of respondents albeit with different routes of administration. CONCLUSIONS: This survey provides interesting preliminary data that could help facilitate and optimize the management of patients with cancer and diabetes, promoting the delivery of an organic answer to fragmented assistance, to potentially inappropriate behaviors, and to a tailored therapy in a context of particular clinical fragility. PMID- 29596951 TI - A randomized controlled trial to compare the effects of sulphonylurea gliclazide MR (modified release) and the DPP-4 inhibitor vildagliptin on glycemic variability and control measured by continuous glucose monitoring (CGM) in Brazilian women with type 2 diabetes. AB - AIMS: This study aims to evaluate whether there is a difference between the effects of vildagliptin and gliclazide MR (modified release) on glycemic variability (GV) in women with type 2 diabetes (T2DM) as evaluated by continuous glucose monitoring (CGM). METHODS: An open-label, randomized study was conducted in T2DM women on steady-dose metformin monotherapy which were treated with 50 mg vildagliptin twice daily or 60-120 mg of gliclazide MR once daily. CGM and GV indices calculation were performed at baseline and after 24 weeks. RESULTS: In total, 42 patients (age: 61.9 +/- 5.9 years, baseline glycated hemoglobin (HbA1c): 7.3 +/- 0.56) were selected and 37 completed the 24-week protocol. Vildagliptin and gliclazide MR reduced GV, as measured by the mean amplitude of glycemic excursions (MAGE, p = 0.007 and 0.034, respectively). The difference between the groups did not reach statistical significance. Vildagliptin also significantly decreased the standard deviation of the mean glucose (SD) and the mean of the daily differences (MODD) (p = 0.007 and 0.030). CONCLUSIONS: Vildagliptin and gliclazide MR similarly reduced the MAGE in women with T2DM after 24 weeks of treatment. Further studies are required to attest differences between vildagliptin and gliclazide MR regarding glycemic variability. PMID- 29596953 TI - Measuring the reliability and validity of the Greek edition of the Diabetes Quality of Life Brief Clinical Inventory. AB - BACKGROUND: The present study focuses on studying the validity and reliability of the Greek edition of DQOL-BCI. DQOL-BCI includes 15 questions-elements that are evaluated on a 5-grade scale like Likert and two general form-shapes. METHODS: The translation process was conducted in conformity with the guidelines of EuroQol group. A non-random sample of 65 people-patients diagnosed with diabetes I and II was selected. The questionnaire that was used to collect the data was the translated version of DQOL-BCI, and included the demographic characteristics of the interviewees. The content validity of DQOL-BCI was re-examined from a team of five experts (expert panel) for qualitative and quantitative performance. The completion of the questionnaire was done via a personal interview. RESULTS: The sample consisted of 58 people (35 men and 23 women, 59.9 +/- 10.9 years). The translation of the questionnaire was found appropriate in accordance to the peculiarities of the Greek language and culture. The largest deviation of values is observed in QOL1 (1.71) in comparison to QOL6 (2.98). The difference between the standard deviations is close to 0.6. The statistics results of the tests showed satisfactory content validity and high construct validity, while the high values for Cronbach alpha index (0.95) reveal high reliability and internal consistency. CONCLUSIONS: The Greek version of DQOL-BCI has acceptable psychometric properties and appears to demonstrate high internal reliability and satisfactory construct validity, which allows its use as an important tool in evaluating the quality of life of diabetic patients in relation to their health. PMID- 29596955 TI - Alterations of complex mismatch negativity (cMMN) elicited by a two-tone pattern paradigm in early-phase psychosis. AB - The mismatch negativity (MMN) is a component of the event-related potential (ERP) elicited by a change in auditory stimulation (e.g., the occurrence of a deviant sound that violates the rules or regularities of the preceding stimulus sequence) regardless of whether one is attending to the change or not. As such, the MMN provides a useful index of pre-attentive cognition. While decreases in MMN amplitude are robustly observed in chronic schizophrenia, these deficits are less consistently present at the early phase of the illness. The current study utilizes a two-tone pattern paradigm that requires more complex computations than typical oddball stimulus presentations, which may be more appropriate for elucidating MMN deficits in an early phase psychosis (EP) sample. The stimuli were a standard sequence consisting of two alternating tones with different tonal frequencies (eg. ABABAB...), with MMN-eliciting pattern violations created by repetitions of either the A or the B tone. EEG recordings of 15 EP participants and 12 healthy controls (HCs) were collected. While no between-group differences were observed, MMN amplitudes in the EP group were correlated with positive and negative psychosis symptom scores. Follow-up analysis stratifying EP participants according to illness duration showed a reduced MMN amplitude in EP participants with a longer (2+ years) duration of illness, but not in EP participants who were within the first year of illness. These findings suggest a two-tone pattern paradigm may be useful in characterizing MMN-indexed cortical impairment later in the early phase of the illness, but not at first episode. PMID- 29596954 TI - Usefulness of glycated albumin as a biomarker for glucose control and prognostic factor in chronic kidney disease patients on dialysis (CKD-G5D). AB - In chronic kidney disease patients on dialysis (CKD-G5D) accurate assessment of glycemic control is vital to improve their outcome and survival. The best glycemic marker for glucose control in these patients is still debated because several clinical and pharmacological factors may affect the ability of the available biomarkers to reflect the patient's glycemic status properly. This review discusses the role of glycated albumin (GA) both as a biomarker for glucose control and as a prognostic factor in CKD-G5D; it also looks at the pros and cons of GA in comparison to the other markers and its usefulness in hemodialysis and peritoneal dialysis. PMID- 29596956 TI - Individual differences in infants' neural responses to their peers' cry and laughter. AB - Infants' ability to process others' emotional expressions is fundamental for their social development. While infants' processing of emotions expressed by faces and speech has been more extensively investigated, less is known about how infants process non-verbal vocalizations of emotions. Here, we recorded frontal N100, P200, and LPC event-related potentials (ERPs) from 8-month-old infants listening to sounds of other infants crying, laughing, and coughing. Infants' temperament was measured via parental report. Results showed that processing of emotional information from non-verbal vocalizations was associated with more negative N100 and greater LPC amplitudes for peer's crying sounds relative to positive and neutral sounds. Temperament was further related to the N100, P200, and LPC difference scores between conditions. One important finding was that infants with improved ability to regulate arousal exhibited increased sustained processing of peers' cry sounds compared to both laughter and cough sounds. These results emphasize the relevance of considering the temperamental characteristics in understanding the development of infant emotion information processing, as well as for formulating comprehensive theoretical models of typical and atypical social development. PMID- 29596957 TI - Suppression of no-longer relevant information in Working Memory: An alpha-power related mechanism? AB - Selective attention can enhance Working Memory (WM) performance by selecting relevant information, while preventing distracting items from encoding or from further maintenance. Alpha oscillatory modulations are a correlate of visuospatial attention. Specifically, an enhancement of alpha power is observed in the ipsilateral posterior cortex to the locus of attention, along with a suppression in the contralateral hemisphere. An influential model proposes that the alpha enhancement is functionally related to the suppression of information. However, whether ipsilateral alpha power represents a mechanism through which no longer relevant WM representations are inhibited has yet not been explored. Here we examined whether the amount of distractors to be suppressed during WM maintenance is functionally related to alpha power lateralized activity. We measure EEG activity while participants (N = 36) performed a retro-cue task in which the WM load was varied across the relevant/irrelevant post-cue hemifield. We found that alpha activity was lateralized respect to the locus of attention, but did not track post-cue irrelevant load. Additionally, non-lateralized alpha activity increased with post-cue relevant load. We propose that alpha lateralization associated to retro-cuing might be related to a general orienting mechanism toward relevant representation. PMID- 29596958 TI - Transfer of plasmid into the pentose-fermenting yeast Pachysolen tannophilus. AB - The pentose-fermenting yeast Pachysolen tannophilus can convert glucose and xylose in lignocellulosic hydrolysates to ethanol. However, it performs poorly in industrially relevant lignocellulosic hydrolysates containing mixed sugars and inhibitors. Efforts have been directed at improving the performance of this yeast to enable efficient lignocellulosic biomass conversion. While some successes have been reported using random mutagenesis and/or hybridization-based approaches, further genetic improvement of this yeast is hampered by the lack of efficient gene transfer methods as well as limited genetic information to guide further construction of robust strains of P. tannophilus. In this study, we aimed to address this short-coming by establishing the optimal conditions needed for efficient gene transfer into P. tannophilus. We ascertained that plasmids can be transferred into P. tannophilus through trans-kingdom conjugation or lithium acetate (LiAc) transformation. The efficiency of plasmid YEp13 (2-micron, LEU2) transferred into a P. tannophilus leucine auxotroph (Leu-) reached as high as 1.93 * 10-2 transconjugants per input recipient and 3.25 * 104 transformants per MUg plasmid DNA through trans-kingdom conjugation and transformation, respectively. In trans-kingdom conjugation, the number of recipient P. tannophilus cells played an important role, while the ratio of donor (Escherichia coli) to recipient cells was less important. For efficient transformation in P. tannophilus, the use of PEG 3350 was essential, as no transformants were obtained in its absence. The transformation efficiency increased with the addition of single-stranded carrier DNA and incubation at 30 degrees C for >60 min. Plasmids with different replication origins or 2-micron plasmids with different CUG codon optimized antibiotic resistance markers were unable to transform P. tannophilus under our experimental conditions. The results are of interest in the genetic manipulation and improvement of P. tannophilus. PMID- 29596959 TI - Two efficient methods for isolation of high-quality genomic DNA from entomopathogenic fungi. AB - Conventional and commercial methods for isolation of nucleic acids are available for fungal samples including entomopathogenic fungi (EPF). However, there is not a unique optimal method for all organisms. The cell wall structure and the wide range of secondary metabolites of EPF can broadly interfere with the efficiency of the DNA extraction protocol. This study compares three commercial protocols: DNeasy(r) Plant Mini Kit (Qiagen), Wizard(r) Genomic DNA Purification Kit (Promega), and AxygenTM Multisource Genomic DNA Miniprep Kit (Axygen) and three conventional methods based on different buffers: SDS, CTAB/PVPP, and CTAB/beta mercaptoethanol versus three cell lysis procedures: liquid nitrogen homogenization and two bead-beating materials (i.e., tungsten-carbide and stainless-steel) for four representative species of EPF (i.e., Beauveria bassiana, Hirsutella citriformis, Isaria javanica, and Metarhizium anisopliae). Liquid nitrogen homogenization combined with DNeasy(r) Plant Mini Kit (i.e., QN) or SDS buffer (i.e., SN) significantly improved the yield with a good purity (~1.8) and high integrity (>20,000 bp) of genomic DNA in contrast with other methods, also, these results were better when compared with the two bead-beating materials. The purified DNA was evaluated by PCR-based techniques: amplification of translation elongation factor 1-alpha (TEF) and two highly sensitive molecular markers (i.e., ISSR and AFLP) with reliable and reproducible results. Despite a variation in yield, purity, and integrity of extracted DNA across the four species of EPF with the different DNA extraction methods, the SN and QN protocols maintained a high-quality of DNA which is required for downstream molecular applications. PMID- 29596960 TI - Improving the selection efficiency of the counter-selection marker pheS* for the genetic engineering of Bacillus amyloliquefaciens. AB - Bacillus subtilis pheS was genetically modified to obtain a counter-selection marker with high selection efficiency in Bacillus amyloliquefaciens. The application of the new replication-thermosensitive integrative vector pNZTM1, containing this marker, pheSBsT255S/A309G, with a two-step replacement recombination procedure provides an effective tool for the genetic engineering of industrially important Bacillus species. PMID- 29596961 TI - Protein restriction and cancer. AB - Protein restriction without malnutrition is currently an effective nutritional intervention known to prevent diseases and promote health span from yeast to human. Recently, low protein diets are reported to be associated with lowered cancer incidence and mortality risk of cancers in human. In murine models, protein restriction inhibits tumor growth via mTOR signaling pathway. IGF-1, amino acid metabolic programing, FGF21, and autophagy may also serve as potential mechanisms of protein restriction mediated cancer prevention. Together, dietary intervention aimed at reducing protein intake can be beneficial and has the potential to be widely adopted and effective in preventing and treating cancers. PMID- 29596962 TI - New isopimarane diterpenes and nortriterpene with cytotoxic activity from Ephorbia alatavica Boiss. AB - Three new isopimarane diterpenes and one new nor-triterpenes, along with five known diterpenes were isolated from the whole areal part of Ephorbia alatavica Boiss. The structures of the new compounds (1-4) were determined based on extensive spectroscopic analysis, including HR-ESIMS, 1D and 2D NMR data. A plausible biosynthetic pathway for new compounds (1-4) were hypothesized. All isolated compounds were screen for cytotoxicity activity against MCF-8, HeLa and A549 cell lines in vitro by MTT assay. New compound 1 and known 9 showed potential cytotoxic activities with IC50 values of 15.327 MUg/mL, 23.066 MUg/mL against MCF-8 cell lines, compound1 showed noteworthy cytotoxic activity with IC50 13.033 MUg/mL against A549 cancer cell line. New compounds 2, 4 and 4 showed moderate cytotoxic activities three human cancer lines with IC50 value around 50 MUg/mL, which compared with positive control doxorubicin (DOX). PMID- 29596963 TI - The effect of interaction between EtOH dosage and exposure time on gene expression in DPSC. AB - Alcohol (EtOH) dosage and exposure time can affect gene expression. However, whether there exists synergistic effect is unknown. Here, we analyzed the hDPSC gene microarray dataset GSE57255 downloaded from Gene Expression Omnibus and found that the interaction between EtOH dosage and exposure time on gene expression are statistically significant for two probes: 201917_s_at near gene SLC25A36 and 217649_at near gene ZFAND5. GeneMania showed that SLC25A36 and ZFAND5 were related to 20 genes, three of which had alcohol-related functions. WebGestalt revealed that the 22 genes were enriched in 10 KEGG pathways, four of which are related to alcoholic diseases. We explored the possible nonlinear interaction effect and got 172 gene probes with significant p-values. However, no significantly enriched pathways based on the 172 probes were detected. Our analyses indicated a possible molecular mechanism that could help explain why alcohol consumption has both deleterious and beneficial effects on human health. PMID- 29596964 TI - Low bone density and fractures before and after pediatric lung transplantation. AB - INTRODUCTION: Children undergoing lung transplant are at risk for low bone mineral density (BMD) and fractures. The effect of lung transplantation on bone health in pediatric patients is unknown. MATERIALS AND METHODS: We performed a retrospective chart review of all patients ages 2-21 years who underwent lung transplantation at our hospital from January 2000 to January 2015. RESULTS: 51 patients were studied. At the time of transplant evaluation, BMD Z-score was -2.2 +/- 1.4, and 59% of patients had low BMD. BMD Z-score declined in the first year after treatment and returned to near-baseline by the third post-transplant year. Fractures occurred in 9 patients (18%) before and 15 patients (29%) after transplant. Bisphosphonate use was associated with improvement in BMD Z-score and lower mortality risk. CONCLUSIONS: Pediatric patients had a high prevalence of low BMD at the time of lung transplant evaluation. BMD Z-scores declined in the year after transplant and returned to the pre-transplant level by the third post transplant year while remaining below normal levels. Fractures were common at sites associated with significant morbidity. These findings support efforts to optimize bone health before and after pediatric lung transplantation, and future studies are needed to evaluate the role of bisphosphonates in these patients. PMID- 29596965 TI - Oxytocin Inhibits Corticosterone-induced Apoptosis in Primary Hippocampal Neurons. AB - Stress is an adaptive and coordinated response to endogenous or exogenous stressors that pose an unpleasant and aversive threat to an individual's homeostasis and wellbeing. Glucocorticoids, corticosterone (CORT) in rodents and cortisol in humans, are adrenal steroids which are released in response to stressful stimuli. Although they help individuals to cope with stress, their overexposure in animals has been implicated in hippocampal dysfunction and neuronal loss. Oxytocin (OT) plays an active role in adaptive stress-related responses and protects hippocampal synaptic plasticity and memory during stress. In this study, we showed that OT protects primary mouse hippocampal neurons from CORT-induced apoptosis. OT receptors (OTR) were expressed in primary mouse hippocampal neurons and glial cells. CORT induced apoptosis in hippocampal neurons, but had no effect on apoptosis in glial cells. OT inhibited CORT-induced apoptosis in primary hippocampal neurons. OT was unable to protect primary hippocampal neurons prepared from OTR KO mice from CORT-induced apoptosis. These results indicate that OT has inhibitory effects on CORT-induced neuronal death in primary hippocampal neurons via acting on OTR. The findings suggest a therapeutic potential of OT in the treatment of stress-related disorders. PMID- 29596966 TI - Characterization of Hit Compounds Identified from High-throughput Screening for their Effect on Blood-brain Barrier Integrity and Amyloid-beta Clearance: In Vitro and In Vivo Studies. AB - In Alzheimer's disease (AD) the blood-brain barrier (BBB) is compromised, thus therapeutic targeting of the BBB to enhance its integrity and function could be a unique approach to treat, slow or hold the progression of AD. Recently, we have developed an in vitro high-throughput screening assay to screen for compounds that increase the integrity of a cell-based BBB model. Results from primary screen identified multiple hit compounds that enhanced the monolayer integrity. Herein, further characterization of selected hit compounds, namely 8 bromoguanosine cyclic monophosphate, JW74, 1,10-phenanthroline monohydrate, SB216763 and alpha-tocopherol was performed. Compounds were subjected to concentration-dependent studies to determine their EC50 and potency to enhance the cell-based model integrity by the Lucifer Yellow permeability and amyloid beta (Abeta) transport across the monolayer. The compounds demonstrated different EC50s to enhance the monolayer integrity ranging from 0.4 to 12.8 uM, and different effect on enhancing Abeta transport with highest transport observed for alpha-tocopherol (2.2-fold increase). Such effects were associated with increased levels of tight junction proteins such as claudin-5 and/or ZO-1, and Abeta major transport proteins LRP1 and P-glycoprotein. In vivo studies for alpha-tocopherol were performed in AD mouse model; consistent with the in vitro results alpha tocopherol significantly increased BBB integrity measured by IgG extravasation, and reduced brain Abeta levels. In conclusion, findings support our developed cell-based BBB model as a functional predictive in vivo tool to select hit compounds, and suggest that enhancing BBB tightness and function has the potential to reduce Abeta pathology associated with AD. PMID- 29596967 TI - Parabens and their effects on the endocrine system. AB - Preservatives (ingredients which inhibit growth of microorganisms) are used to prolong shelf life of various foods, cosmetics, and pharmaceutical products. Parabens are one of the most popular preservatives used in the aforementioned products and is currently being used worldwide. Parabens are easily absorbed by the human body. Thus, it is important to discuss about their safety with respect to human physiology. In view of the current literature, which classifies parabens as a group of endocrine disrupting chemicals (EDCs), it seems that the precise assessment of their influence on the human endocrine system is particularly important. Disruption of the endocrine homoeostasis might lead to multidirectional implications causing disruption of fitness and functions of the body. Therefore, in this review article, we aimed to summarize the current literature on properties, occurrence, and metabolism of parabens as well as to present recent progress in knowledge about their influence on the human endocrine system. PMID- 29596969 TI - Global gene expression analysis indicates that small luteal cells are involved in extracellular matrix modulation and immune cell recruitment in the bovine corpus luteum. AB - Genome wide mRNA expression analysis of small and large luteal cells, isolated from the mature staged corpora lutea (CL), was not performed in any species. In the current study, we have isolated bovine small and large luteal cells from mid cycle (day 10-11) animals and characterized their transcriptomes using "GeneChipTM Bovine Gene 1.0 ST Arrays". A total of 1276 genes were identified to be differentially expressed between small and large luteal cells. Data evaluation revealed that novel functions, extracellular matrix synthesis and immune cell recruitment, were enriched in small luteal cells. On contrary, functions regarding the regulation of folliculogenesis, luteal regression, fatty acid and branched chain amino acid metabolism were differentially enriched in large luteal cells. Overall, the current data offer a first and detailed insight into the functional roles of small and large luteal cells in the mature bovine corpus luteum. PMID- 29596968 TI - Sequential gene regulatory events leading to glucocorticoid-evoked apoptosis of CEM human leukemic cells:interactions of MAPK, MYC and glucocorticoid pathways. AB - Gene expression responses to glucocorticoid (GC) in the hours preceding onset of apoptosis were compared in three clones of human acute lymphoblastic leukemia CEM cells. Between 2 and 20h, all three clones showed increasing numbers of responding genes. Each clone had many unique responses, but the two responsive clones showed a group of responding genes in common, different from the resistant clone. MYC levels and the balance of activities between the three major groups of MAPKs are known important regulators of glucocorticoid-driven apoptosis in several lymphoid cell systems. Common to the two sensitive clones were changed transcript levels from genes that decrease amounts or activity of anti-apoptotic ERK/MAPK1 and JNK2/MAPK9, or of genes that increase activity of pro-apoptotic p38/MAPK14. Down-regulation of MYC and several MYC-regulated genes relevant to MAPKs also occurred in both sensitive clones. Transcriptomine comparisons revealed probable NOTCH-GC crosstalk in these cells. PMID- 29596970 TI - Cross-cultural adaptation of Roland-Morris Disability Questionnaire needs to assess the measurement properties: a systematic review. AB - OBJECTIVE: To assess the cross-cultural adaptations of the Roland-Morris Disability Questionnaire (RMDQ). STUDY DESIGN AND SETTING: English and Chinese databases were searched through December 2017. Cross-cultural adaptation and measurement properties were evaluated using the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and the Quality Criteria for Psychometric Properties of Health Status Questionnaire. RESULTS: Among 34 studies, there were 31 RMDQ adaptations for 26 different languages/cultures. In the cross-cultural adaptation process, few studies reported expert committees completely constituted (3/31), and only 10 studies completed the test of the prefinal version (10/31) due to insufficient sample sizes. As for the measurement properties, content validity (31/31) and construct validity (24/31) were assessed in most of the adaptations, whereas internal consistency (0/31), agreement (5/31), responsiveness (3/31), interpretability (6/31), and floor and ceiling effects (6/31) were not. CONCLUSION: The Hungarian and Moon's Korean adaptations were the highest quality translations. Where there were multiple adaptations for a language/culture, the Moon's Korean and Fan's simplified Chinese-Chinese Mainland adaptations are recommended over the other Korean or simplified Chinese Chinese Mainland adaptations. Further studies are required to fully assess the measurement properties of the Arabic-Moroccan, Arabic-Tunisian, German-Austrian, Greek, Gujarati, Kim's Korean, Persian-Iranian, Polish, He's simplified Chinese Chinese Mainland, Spanish, Spanish-Chilean, Thai, traditional Chinese-Taiwan, and Turkish adaptations of the RMDQ.

AB - OBJECTIVES: To assess markers of selection bias risk in a sample of recently published cluster randomized controlled trials compared with individually randomized trials. STUDY DESIGN AND SETTING: We used OVID Medline and the online archives of the Journal of the American Medical Association to search for cluster randomized trials published between January 2015 and June 2017 from four high impact journals and compared them to a matched sample of individually randomized trials. RESULTS: We identified 23 cluster trials: 57% (n = 13) described a robust allocation method and 17% (n = 4) recruited all participants before randomization. Four (17%), eight (35%), and 11 (48%) were classified as at low, medium, and high bias risk, respectively. Meta-analysis showed significant age imbalance (-0.05, 95% CI = -0.057 to -0.043, I2 = 93.2%) in cluster trials, while the matched individually randomized trials showed no imbalance (0.005, 95% CI = 0.026 to 0.035, I2 = 0%). Cluster trials finding a statistically significant outcome in their primary measure showed a larger age imbalance (0.082, 95% CI = 0.091 to -0.073, I2 = 87%) than trials finding a nonstatistically significant outcome (0.022, 95% CI = 0.008 to 0.035, I2 = 83%). CONCLUSIONS: There is strong evidence in this sample of an effect of selection bias seen in an imbalance in baseline participant age, something not seen in a comparable sample of individually randomized trials.

(Amaryllidaceae) and Molineria trichocarpa (Wight) N.P. Balakr (Hypoxidaceae): Cytotoxic and antioxidant activities. AB - The present investigation was carried out to evaluate the antioxidant and cytotoxic activities of Pancratium triflorum Roxb and Molineria trichocarpa were collected from South Vagaikulam, Tirunelveli district, Tamil Nadu, India. The antioxidant activities of P. triflorum extracts were as follows with the IC50 values methanol (228.13 MUg/mL) > chloroform (311.33 MUg/mL) > acetone (398.08 MUg/mL) > petroleum ether (410.16 MUg/mL). The antioxidant activities of P. triflorum and M. trichocarpa extracts were as follows with the IC50 values methanol (80.93 MUg/mL) > acetone (98.02 MUg/mL) > chloroform (186.84 MUg/mL) > petroleum ether (209.64 MUg/mL). Among the various extracts of P. triflorum, methanolic extracts showed the strongest phosphomolybdenum reduction (140.56 g AA/100 g). Among the tested extracts, acetone extracts of M. trichocarpa showed maximum inhibition with 71.36 +/- 5.86%. In P. triflorum, chloroform extracts showed maximum inhibition (69.51%). The petroleum ether extract of M. trichocarpa was found to be most effective at which 50% mortality (LC50) and 90% mortality (LC90) of brine shrimp nauplii were found to be 29.22 and 184.82 mg/mL. This study results revealed the antioxidant and cytotoxic properties of P. triflorum and M. trichocarpa. Further investigations are needed to isolate and validate the active principles of the extract responsible various pharmacological properties.

AB - Fimasartan (FMS), an angiotensin II receptor antagonist, is metabolized to FMS S oxide, FMS N-glucuronide, oxidative desulfurized FMS (BR-A-557), and hydroxy-n butyl FMSs. The purpose of this study was to characterize enzymes involved in NADPH-dependent FMS metabolism using recombinant enzymes such as cytochrome P450 (CYP) and flavin-containing monooxygenase (FMO), as well as selective chemical inhibitors. The results showed that CYP, but not FMO, plays a major role in FMS metabolism. CYP2C9, CYP3A4, and CYP3A5 were involved in the formation of FMS S oxide, which was further metabolized to BR-A-557 by CYP3A4/5. CYP2C9 played an exclusive role in n-butyl hydroxylation. The specificity constant (kcat/Km) values for S-oxidation by CYP2C9, CYP3A4, and CYP3A5 were 0.21, 0.34, and 0.19 MUM-1?min-1, respectively. The kcat/Km values of hydroxylation at the 1-, 2-/3-, and 4-n-butyl group in CYP2C9 were 0.0076, 0.041, and 0.035 MUM-1?min-1, respectively. The kcat and Km values provide information for the prediction of FMS metabolism in vivo. In addition, simultaneous determination of the FMS metabolites may be used to evaluate CYP2C9 and CYP3A4/5 activity.

AB - Abnormal interaction of amyloid-beta peptide (Abeta) and metal ions is proved to be related to the etiology of Alzheimer's disease (AD). Using metal chelators to reverse metal-triggered Abeta aggregation has become one of the potential therapies for AD. In our work, the effect of metal chelator, NBD-BPEA, on Zn2+- or Cu2+-mediated Abeta40 aggregation and neurotoxicity has been systematically studied. NBD-BPEA exhibits the capability to inhibit the metal-mediated Abeta40 aggregation and disassemble performed Abeta40 aggregates. It also prevents the formation of the beta-sheet structure and promotes the reversion of the beta sheet to the normal random coil conformation. Moreover, it can alleviate Zn2+- or Cu2+-Abeta40-induced neurotoxicity, suppress the intracellular ROS and protect against cell apoptosis. These preliminary findings indicate that NBD-BPEA has promising perspective of application in the treatment of AD, and therefore deserve further investigation as potential anti-AD agents. PMID- 29596978 TI - Fast and robust Block-Sparse Bayesian learning for EEG source imaging. AB - We propose a new Sparse Bayesian Learning (SBL) algorithm that can deliver fast, block-sparse, and robust solutions to the EEG source imaging (ESI) problem in the presence of noisy measurements. Current implementations of the SBL framework are computationally expensive and typically handle fluctuations in the measurement noise using different heuristics that are unsuitable for real-time imaging applications. We address these shortcomings by decoupling the estimation of the sensor noise covariance and the sparsity profile of the sources, thereby yielding an efficient two-stage algorithm. In the first stage, we optimize a simplified non-sparse generative model to get an estimate of the sensor noise covariance and a good initialization of the group-sparsity profile of the sources. Sources obtained at this stage are equivalent to those estimated with the popular inverse method LORETA. In the second stage, we apply a fast SBL algorithm with the noise covariance fixed to the value obtained in the first stage to efficiently shrink to zero groups of sources that are irrelevant for explaining the EEG measurements. In addition, we derive an initialization to the first stage of the algorithm that is optimal in the least squares sense, which prevents delays due to suboptimal initial conditions. We validate our method on both simulated and real EEG data. Simulations show that the method is robust to measurement noise and performs well in real-time, with faster performance than two state of the art SBL solvers. On real error-related negativity EEG data, we obtain source images in agreement with the experimental literature. The method shows promise for real time neuroimaging and brain-machine interface applications. PMID- 29596977 TI - Isoline use in crop composition studies with genetically modified crops under EFSA guidance - Short communication. AB - The European Food Safety Authority (EFSA) oversees the safety evaluation of genetically modified (GM) crops in the European Union. EFSA requires inclusion of commercial non-GM reference lines and a non-GM isoline in crop composition studies with GM crops. Reference lines are used to construct equivalence limits for each compositional analyte. Results for the GM line are compared with these equivalence limits to assess compositional equivalence between the GM crop and the non-GM crop. If compositional equivalence cannot be concluded from this comparison, then results for the non-GM isoline can be used to determine if this finding is likely the result of the background non-GM genetics of the GM crop. If this latter comparison is not sufficient to assess the compositional safety of the GM crop, then a biological-relevance assessment for the analytes in question can be completed taking into account the greater body of knowledge of composition for the crop and diets. Thus, the isoline is a useful comparator but not required to assess the compositional safety of the GM crop, and therefore, unavoidable genotype differences between the isoline and GM line should not be grounds for rejection of compositional studies where the biological relevance of potential non-equivalence is addressed. PMID- 29596979 TI - Hemispheric asymmetry and homotopy of resting state functional connectivity correlate with visuospatial abilities in school-age children. AB - Hemispheric specialization of cognitive functions is a developmental process that shapes the brain from the gestational stage to adulthood. Functional connectivity of the resting brain has been largely used to infer the hemispheric organization of the spontaneous brain activity. In particular, two main properties have been largely explored throughout development: hemispheric asymmetry of functional connectivity and homotopic functional connectivity. However, their relation with specific cognitive processes typically associated with hemispheric specialization, such as visuospatial abilities, remains largely unexplored. Such relationships could be particularly relevant for the quest of developmental cognitive biomarkers in childhood, a significant maturation period of visuospatial abilities. Moreover, the relation between asymmetry and homotopy of brain functional connectivity is not well understood. We have examined these two properties in a sample of 60 typically developing children between 6 and 10 years of age, and explored their relation with visuospatial abilities. First, we identified a strong negative relation between homotopy and asymmetry across the brain. In addition, these properties showed areas in the posterior portion of the brain, with significant correlation with performance in visual memory and visual attention tasks. These results highlight the relevance of the hemispheric organization of spontaneous brain activity for developmental cognition, particularly for visuospatial abilities. PMID- 29596980 TI - SMAC: Spatial multi-category angle-based classifier for high-dimensional neuroimaging data. AB - With the development of advanced imaging techniques, scientists are interested in identifying imaging biomarkers that are related to different subtypes or transitional stages of various cancers, neuropsychiatric diseases, and neurodegenerative diseases, among many others. In this paper, we propose a novel spatial multi-category angle-based classifier (SMAC) for the efficient identification of such imaging biomarkers. The proposed SMAC not only utilizes the spatial structure of high-dimensional imaging data but also handles both binary and multi-category classification problems. We introduce an efficient algorithm based on an alternative direction method of multipliers to solve the large-scale optimization problem for SMAC. Both our simulation and real data experiments demonstrate the usefulness of SMAC. PMID- 29596981 TI - The vestibulomyogenic balance response is elevated following high-intensity lengthening contractions of the lower limb. AB - The purpose was to investigate whether exercise-induced muscle weakness of the plantar and dorsiflexors through high-intensity lengthening contractions increases the vestibulomyogenic balance response. Nine males (~25 years) participated in three experimental testing days to evaluate the vestibular control of standing balance and neuromuscular function of the plantar and dorsiflexors pre- and post (30 min, and 1 and 7 days) high-intensity lengthening plantar and dorsiflexions. To evaluate the vestibular-evoked balance response, participants stood quietly on a force plate while exposed to continuous, random electrical vestibular stimulation (EVS) for two 90-s trials. Relationships between EVS-antero-posterior (AP) forces and EVS-medial gastrocnemius electromyography (EMG) were estimated in the frequency domain (i.e., coherence). Weakness of the right plantar and dorsiflexors were assessed using maximal voluntary contraction (MVC) torque. The lengthening contractions induced a 13 and 24% reduction in plantar and dorsiflexor MVC torque, respectively (p < 0.05) of the exercised leg, which did not recover by 1 day post. The EVS-EMG coherence increased over a range of frequencies up to 7 days post compared to pre lengthening contractions. Conversely, EVS-AP forces coherence exhibited limited changes. The greater EVS-EMG coherence post exercise-induced muscle weakness may be a compensatory mechanism to maintain the whole-body vestibular-evoked balance response when muscle strength is reduced.

AB - BACKGROUND & AIMS: Diagnosis of diarrhea-predominant irritable bowel syndrome (IBS-D) relies on the Rome IV symptom-based criteria, which are imperfect for separating functional vs organic disease. Biomarker tests for IBS-D might be added to symptom data to allow clinicians to make more accurate and precise diagnoses in a cost-effective manner. We tested the economic consequences of using a range of hypothetical IBS-D biomarkers, and explored at what cost and level of accuracy a biomarker becomes cost effective. We produced a framework for payers to evaluate the return on an investment of implementing IBS-D biomarkers of varying accuracy and cost. METHODS: We used decision analysis software to evaluate a hypothetical cohort of patients who met Rome IV criteria for IBS-D. We conducted cost-utility and budget impact analyses of 2 competing approaches: usual care or an IBS biomarker-based diagnostic approach. Patients in the usual care group received empiric IBS treatment; non-responders received additional diagnostic tests for organic disease. In the group evaluated with a biomarker test, those with a positive result received IBS treatment before additional diagnostic analyses, whereas patients with a negative result underwent upfront diagnostic testing. Outcomes were incremental cost per quality-adjusted life year gained (third-party payer perspective) and incremental per-member per-month cost. RESULTS: In the base-case analysis, using a willingness-to-pay threshold of $100,000/quality-adjusted life year, we found that biomarkers are not cost effective when the biomarker test costs more than $846, even if the test is 100% accurate in detecting IBS-D. In probabilistic analysis using 1,000 simulations, most trials (75% or more) show that the biomarker-based diagnostic approach is cost effective above the following accuracy thresholds: a $100 biomarker test with 51% accuracy, a $200 test with 57% accuracy, a $300 test with 63% accuracy, a $400 test with 69% accuracy, a $500 test with 76% accuracy, a $600 test with 82% accuracy, a $700 test with 89% accuracy, and a $800 test with 94% accuracy. CONCLUSIONS: In decision analysis of a hypothetical cohort of patients who met Rome IV criteria for IBS-D, we identified cost and accuracy thresholds that can guide investigators and payers as they develop, validate, price, and/or reimburse IBS-D biomarker tests for use in everyday clinical practice. PMID- 29596986 TI - Is Modest Drinking Good for the Liver? PMID- 29596988 TI - The detection and prevalence of leukotoxin gene variant strains of Fusobacterium necrophorum in footrot lesions of sheep in Kashmir, India. AB - The objective of this study was to determine the prevalence and identification of leukotoxin gene, lktA, variant strains of Fusobacterium necrophorum in the footrot lesions of sheep. The detection of F. necrophorum was carried out by PCR targeting the lktA gene fragment and identification of lktA variant strains was done by PCR-single stranded conformational polymorphism (PCR-SSCP) and gene sequencing. Of the 450 swabs collected from footrot lesions of sheep, 117 were lktA-positive for F. necrophorum. Of the 50 swabs collected from apparently asymptomatic sheep, only one was lktA-positive for F. necrophorum. The overall prevalence of F. necrophorum in footrot affected sheep in Kashmir valley was 26%, and ranged from 20 to 34.8%, respectively. PCR-SSCP of lktA gene fragment analysis revealed three lktA variants, designated as JKS-F1/F2/F3, while two samples (1.7%) showed multiple lktA variant strains of F. necrophorum in a single footrot-affected sheep hoof. This appears to be the first report on the presence of more than one lktA variant of F. necrophorum in a footrot lesion of sheep. The JKS-F3 lktA variant was the most frequent (75.4%), followed by JKS-F2 (14.4%) and JKS-F1 (8.4%), respectively. Among the three lktA variants identified, JKS-F3 was detected in 74 (86.0%) samples from severe footrot affected sheep with a lesion score of 4. The data suggest that JKS-F3 is the predominant lktA variant of F. necrophorum and is associated with severe footrot in sheep. Hence, JKS-F3 may be a significant variant contributing to the severity and duration of the disease in sheep.

AB - BACKGROUND & AIMS: Endpoints in randomized controlled trials (RCTs) of Crohn's disease (CD) are changing. We performed a systematic review of efficacy and safety outcomes reported in placebo-controlled RCTs of patients with CD. METHODS: We searched the MEDLINE, EMBASE, and the Cochrane Library through March 1, 2017 for placebo-controlled RCTs of adult patients with CD treated with aminosalicylates, immunomodulators, corticosteroids, biologics, and oral small molecules. Efficacy and safety outcomes, definitions, and measurement tools were collected and stratified by decade of publication. RESULTS: Our final analysis included 116 RCTs (81 induction, 44 maintenance, 7 postoperative prevention trials, comprising 27,263 patients). Clinical efficacy endpoints were reported in all trials; the most common endpoint was CD activity index score. We identified 38 unique definitions of clinical response or remission and 32 definitions of loss of response. Definitions of endoscopic response, remission, and endoscopic healing were also heterogeneous, evaluated using the CD endoscopic index of severity, the simple endoscopic score for CD, ulcer resolution, and Rutgeerts' Score for postoperative endoscopic appearance. Histologic outcomes were reported in 11.1% of induction trials, 2.3% of maintenance trials, and 14.3% of postoperative prevention trials. Biomarker outcomes were reported in 81.5% induction trials, 68.2% of maintenance trials, and 42.9% of postoperative prevention trials. Safety outcomes were reported in 93.8% of induction trials, 97.7% of maintenance trials, and 85.7% of postoperative prevention trials. CONCLUSIONS: In this systematic review, we demonstrate heterogeneity in definitions of response and remission, and changes in outcomes reported in RCTs of CD. It is a priority to select a core set of outcomes to standardize efficacy and safety evaluation in trials of patients with CD. PMID- 29596989 TI - High-level expression, purification, and enzymatic characterization of a recombinant Aspergillus sojae alkaline protease in Pichia pastoris. AB - An alkaline protease (Ap) was cloned from Aspergillus sojae GIM3.33 via RT-PCR technique. A truncated Ap without the signal peptide was successfully expressed in the Pichia pastoris KM71 strain. The following describes the optimal process conditions for the recombinant engineering of a strain expressing a recombinant Ap (rAp) in a triangular flask: inoculum concentration OD600 value 20.0 in 40 mL working volume (in 500 mL flasks), methanol addition (1.0%; volume ratio), 0.02% biotin solution (60 MUL), and YNB primary concentration (13.0 g/L). Under these conditions, the protease activity of rAp in the fermentation broth reached 400.4 +/- 40.5 U/mL after induction for three days. The rAp was isolated and purified, and its enzymatic characteristics were tested. Its optimal pH was 10.0, and it remained stable in a pH range of 7.0-10.0. Its optimal temperature was 45 degrees C and it retained >50% activity at 40 degrees C for 60 min. The rAp activity was significantly inhibited by PMSF, Zn2+ and Fe2+ and the rAp had a broad substrate specificity for natural proteins and synthetic peptide substrates, and preferred substrates at P1 position with large hydrophobic side chain groups. Compared to Papain (8.7%) and Alcalase (12.2%), the degree of hydrolysis of rAp to soy protein isolate was 16.5%; therefore, rAp was a good candidate for the processing of food industry byproducts. PMID- 29596990 TI - Improved inducible expression of Bacillus naganoensis pullulanase from recombinant Bacillus subtilis by enhancer regulation. AB - Pullulanase is crucial to the specific hydrolysis of branch points in amylopectin and is generally employed as an important enzyme in the starch-processing industry. Recombinant Bacillus subtilis that employs an inducible promoter would be a suitable candidate for pullulanase expression because of its safety and controllable production, but its level of pullulanase activity is relatively low. In this study, we investigated the effect of the enhancers DegQ, DegU, and DegS on pullulanase expression in a recombinant B. subtilis inducible system. The genes degQ, degU, and degS were introduced to the recombinant plasmid pMA0911 PsacB-pul harboring the promoter PsacB, signal peptide LipA, and gene encoding pullulanase. The regulatory effects of the enhancers involved in recombinant plasmids on pullulanase expression level were evaluated in B. subtilis WB600 and WB800, respectively. The positive regulation of DegQ toward pullulanase expression was detected from B. subtilis WB800, leading to a 60% increase in enzyme activity. In addition, enzyme activity was further enhanced by inserting the degQ gene to the position closer to the promoter PsacB. Consequently, pullulanase activity reached 26.5 U ml-1 from the B. subtilis WB800/pMA0911-PsacB pul-degQ(N) after expression optimization, which was a 5.9-fold increase compared to that of the original strain B. subtilis WB800/pMA0911-PsacB-pul. Hence, the inducible expression of the enzyme was efficiently enhanced by regulating the enhancer DegQ from recombinant B. subtilis WB800. PMID- 29596991 TI - A novel strategy to produce high level and high purity of bioactive IL15 fusion proteins from mammalian cells. AB - IL15, a member of the common gamma chain receptor (gammac) cytokine family, is gaining attention in recent years as one of the most promising anti-tumor agents. IL15 regulates T cell activation and proliferation, promotes the survival of CD8+ CD44hi memory T cells and is also essential for NK cell expansion and development. Despite the attraction of developing IL15 as an anti-cancer agent, production of recombinant IL15 has proven to be difficult due to the stringent control of IL15 expression at the transcriptional, translational and the post translational levels. Furthermore, the bioactivity of IL15 fused to an extra functional domain that is isolated from mammalian cells is generally inferior to recombinant IL15 produced by E. coli. In this study, we report that Lysine 86 in IL15 is responsible for the instability in mammalian cells when its C-terminus is fused to the albumin binding scFv (IL15-A10m3). We demonstrate that K86A or K86R mutants increased the expression of the fusion protein from HEK293 cells. When the wild type IL15 is used for the fusion, no recombinant IL15 fusion was detected in the culture media. Additionally, we determined that the residue 112 in IL15 is critical for the bioactivity of IL15-A10m3. Examination of single and double mutants provides a better understanding of how IL15 engages with its receptor complex to achieve full signaling capacity. The results of our experiments were successfully applied to scale up production to levels up to 50 mg/L and >10 mg/L of >95% pure monomeric recombinant fusion proteins after a 2 step purification from culture media. More importantly, the recombinant fusion protein produced is fully active in stimulating T cell proliferation, when compared to the recombinant wild type IL15.

AB - Detection of donor-specific antibodies (DSA) has improved the risk classification and post-transplant evaluation of kidney recipients. Moreover, assessment of DSA C1q-binding ability has been shown to improve the individual risk classification of transplant patients for allograft loss, especially when detected after transplantation. The aim of this study was to evaluate the additional clinical impact of C1q-binding DSA detection in a population that was extensively monitored for DSA and MFI alterations. Forty-two kidney allograft recipients were followed-up at multiple time points for up to 5 years after transplantation for the presence of anti-HLA DSA-IgG total. The samples that were positive for these antibodies were retrospectively tested for the presence of complement-binding antibodies. Overall, 24 patients presented DSA, 29% (7) of which also produced complement-binding DSA. Compared to patients with non-C1q-binding DSA and non sensitized patients, patients with C1q-binding DSA after transplantation had the lowest allograft survival rate at 5 years (p = 0.042) and showed a lower estimated glomerular filtration rate (based on the Modification of Diet in Renal Disease formula) during the post-transplant follow-up period (p = 0.01). Thus, post-transplant monitoring for complement-binding DSA is a useful tool for predicting individuals most at risk for allograft failure, and might also be beneficial for evaluation of immunosuppression regimens. PMID- 29596993 TI - Immune modulation by silencing CD80 and CD86 production in dendritic cells using small hairpin RNA to reduce heart transplant rejection. AB - RNA interference (RNAi) plays a potential role in organ transplantation. Small hairpin RNA (shRNA) is an artificial RNA molecule with a tight hairpin turn that can be used to silence the expression of a target gene. We constructed shRNA targeting on the cluster of differentiation 80 (CD80, B7-1) and the cluster of differentiation 86 (CD86, B7-2) and transfected it into dendritic cells (DCs). Fluorescence real-time PCR and flow cytometry confirmed the gene-silencing effect. Interleukin-2 (IL-2) mRNA expression level decreased in T cells that were cocultured with pB7-shRNA-transfected DCs. For in-vivo experiment, we built mice models of abdominal heterotopic heart transplantation and transfused the models with pB7-shRNA-transfected donor-derived DCs. The survival time of the transplanted heart increased; the grade of organ rejection decreased. IL-2 mRNA expression level decreased and it was positively correlated with the grade of organ rejection. PMID- 29596994 TI - Convergent engineering of syntrophic Escherichia coli coculture for efficient production of glycosides. AB - Synthetic microbial coculture to express heterologous biosynthetic pathway for de novo production of medicinal ingredients is an emerging strategy for metabolic engineering and synthetic biology. Here, taking efficient production of salidroside as an example of glycosides, we design and construct a syntrophic Escherichia coli-E. coli coculture composed of the aglycone (AG) strain and the glycoside (GD) strain, which convergently accommodate biosynthetic pathways of tyrosol and salidroside, respectively. To accomplish this the phenylalanine deficient AG strain was engineered to utilize xylose preferentially and to overproduce precursor tyrosol, while the tyrosine-deficient GD strain was constructed to consume glucose exclusively and to enhance another precursor UDP glucose availability for synthesis of salidroside. The AG and GD strains in the synthetic consortium are obligatory cooperators through crossfeeding of tyrosine and phenylalanine and compatible in glucose and xylose mixture. Through balancing the metabolic pathway strength, we show that the syntrophic coculture was robust and stable, and produced 6.03 g/L of salidroside. It was the de novo production of salidroside for the first time in E. coli coculture system, which would be applicable for production of other important glycosides and natural products. PMID- 29596995 TI - Applying ketamine to alleviate the PTSD-like effects by regulating the HCN1 related BDNF. AB - BACKGROUND: Post-traumatic stress disorder (PTSD) is commonly associated with concurrent anxiety and depression symptoms, and reduce the expression of the Brain-Derived Neurotrophic Factor (BDNF) which promotes the proliferation and survival of neurons. The hyperpolarization-activated cyclic nucleotide-gated channel 1(HCN1) could be inhibited by the ketamine, a drug to alleviate depression and anxiety, and regulated the BDNF expression, however, the effects of ketamine in alleviating PTSD symptoms by regulating the HCN1-related BDNF have been poorly perceived. METHODS: In the present study, the effects of ketamine were examined on the PTSD-like effects in a rat model of PTSD induced by SPS&S procedure. After the SPS&S procedure and model testing, PTSD rats were subjected to behavioral testing and biochemical assessments, followed by single treatment with certain doses of ketamine (5, 10, 15 and 20 mg/kg IP). RESULTS: The results showed that the SPS&S procedure induced severe PTSD-like behaviors, with lower levels of BDNF protein levels and higher level of the HCN1 protein in the prefrontal cortex (PFC). These were reversed by a single administration of ketamine. The ketamine with dose of 15 mg/kg significantly increased locomotor behavior in the open field test, aggrandized exploratory behavior in the elevated plus maze test, and decreased immobility time spent in the forced swim test. Meanwhile, ketamine with dose of 15 mg/kg could increase the BDNF protein level, while down-regulate the expression of the HCN1. Eventually, there was a negative correlation between the level of BDNF and HCN1 in the PFC. CONCLUSION: Ketamine affects the HCN1-related BDNF signaling pathways to alleviate PTSD-like effects in rat. PMID- 29596996 TI - Unpredictable chronic prenatal stress and manifestation of generalized anxiety and panic in rat's offspring. AB - Often the manifestation of anxiety cannot be explained by known environmental or hereditary factors. With this perspective, it has been reported that prenatal stress may lead to emotional disturbances in the offspring. However, studies relating prenatal stress to anxiety are controversial and generally the stressors used do not mimicks the reality experienced by mothers. Thus, this investigation evaluated the effects of an unpredictable chronic stress scheme applied in one of the three gestational weeks of rats on the manifestation of generalized anxiety and panic disorder in the progeny (males), analyzing, respectively, the avoidances and escapes in the elevated T-maze, at the 1st, 3rd or 6th month of progeny life. Control offspring showed increased generalized anxiety disorder and reduced panic at 6 months. The effects of prenatal stress depended on the gestational week where it occurred and on the progeny age: during the 1st gestational week the generalized anxiety decreased in 6 month old rats. Animals in the 3rd month, prenatally stressed during the last gestational week, showed anxiogenesis and panicogenesis, but effects reverted at the 6th month, when they presented anxiolysis and no changes related to panic. Together the results show that not only the gestational period in which the aversive experience occurred was important, but the age of the evaluated progeny, since the type and the intensity of behaviors related to anxiety may vary with the developmental stage. For the model of stress used in the present study, the effects of prenatal stress were more prominent when the exposure occurred during the 3rd gestational week in rats.

AB - The sensitization of cough reflex observed in patients with gastroesophageal reflux disease (GERD) is attributed to activation of vagal C-fibers innervating the esophagus by acid, while the heartburn in GERD is mediated by esophageal acid sensitive C-fibers derived from (dorsal root ganglia) DRG. Here we explored the relationship between cough reflex sensitivity (CRS) and esophageal sensitivity to acid. We evaluated CRS to capsaicin inhalation and esophageal sensitivity to acid (intensity of heartburn evoked by esophageal infusions of acid pH = 3, 2 and 1) in patients with GERD and chronic heartburn before and 3 months after proton pump inhibitor (PPI) treatment. There was no correlation between CRS and esophageal sensitivity to acid at any pH tested. PPI treatment substantially reduced esophageal sensitivity to acid but did not affect CRS. We conclude that a simple direct relationship between CRS and esophageal sensitivity to acid is unlikely. The results indicate that spinal and vagal afferent pathways from the esophagus are probably influenced separately in subjects with GERD. PMID- 29596999 TI - Tithonia diversifolia (Hemsl.) A. Gray as a medicinal plant: A comprehensive review of its ethnopharmacology, phytochemistry, pharmacotoxicology and clinical relevance. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Tithonia diversifolia (TD) is widely valued in several cultures for its medicinal properties. A comprehensive review of the current understanding of this plant species is required due to emerging concerns over its efficacy, toxicity and allergenic potential. AIM OF THE REVIEW: We critically summarized the current evidence on the botany, traditional use, phytochemistry, pharmacology and safety of TD, with the view to provide perspectives for developing more attractive pharmaceuticals of plant origin, but also to lay a new foundation for further investigations on this plant. MATERIALS AND METHODS: A preliminary consultation of search engines such as Web of Science, PubMed, ScienceDirect and other published/unpublished resources provided an overview of extant literature on TD. Then, we meticulously screened all titles, abstracts and full-texts to establish consistency in the application of inclusion criteria. Studies were considered for inclusion if they dealt with taxonomy, global distribution, local and traditional knowledge, phytochemistry, toxicity and biological effects. RESULTS: 1856 articles were retrieved among which 168 were revised and included. Several studies conducted on cell lines and animals provided supporting evidence for some ethnomedicinal claims of extracts from TD. Short-term use of Tithonia extracts were effective and well-tolerated in animals when taken at lower doses. Both the toxic and therapeutic effects were attributed to bioactive principles naturally occurring in this species including sesquiterpene lactones, chlorogenic acid and flavonoids. CONCLUSIONS: T. diversifolia is a valuable source of bioactive compounds with significant therapeutic implications and favourable safety index. However, more rigorously designed investigations are needed to recommend the whole plant or its active ingredients as a medication, and should focus on understanding the multi-target network pharmacology of the plant, clarifying the effective doses as well as identifying the potential interactions with prescribed drugs or other chemicals.

Nonetheless, available algorithms for automatic detection of cough sound have limited sensitivity and the analysis of cough sound often requires input from human observers. Therefore, an algorithm for the cough sound detection with high sensitivity would be very useful for development of automatic cough monitors. Here we present a novel algorithm for cough sounds classification based on 8-dimensional numbers octonions and compare it with the algorithm based on standard neural network. The performance was evaluated on a dataset of 5200 cough sounds and 90000 of non-cough sounds generated from the sound recordings in 18 patients with frequent cough caused by various respiratory diseases. Standard classification algorithm had sensitivity 82.2% and specificity 96.4%. In contrast, octonionic classification algorithm had significantly higher sensitivity 96.8% and specificity 98.4%. The use of octonions for classification of cough sounds improved sensitivity and specificity of cough sound detection. PMID- 29597002 TI - A Phase 1 Trial of CNDO-109-Activated Natural Killer Cells in Patients with High Risk Acute Myeloid Leukemia. AB - Natural killer (NK) cells are an emerging immunotherapy approach to acute myeloid leukemia (AML); however, the optimal approach to activate NK cells before adoptive transfer remains unclear. Human NK cells that are primed with the CTV-1 leukemia cell line lysate CNDO-109 exhibit enhanced cytotoxicity against NK cell resistant cell lines. To translate this finding to the clinic, CNDO-109-activated NK cells (CNDO-109-NK cells) isolated from related HLA-haploidentical donors were evaluated in a phase 1 dose-escalation trial at doses of 3 * 105 (n = 3), 1 * 106 (n = 3), and 3 * 106 (n = 6) cells/kg in patients with AML in first complete remission (CR1) at high risk for recurrence. Before CNDO-109-NK cell administration, patients were treated with lymphodepleting fludarabine/cyclophosphamide. CNDO-109-NK cells were well tolerated, and no dose limiting toxicities were observed at the highest tested dose. The median relapse free survival (RFS) by dose level was 105 (3 * 105), 156 (1 * 106), and 337 (3 * 106) days. Two patients remained relapse-free in post-trial follow-up, with RFS durations exceeding 42.5 months. Donor NK cell microchimerism was detected on day 7 in 10 of 12 patients, with 3 patients having evidence of donor cells on day 14 or later. This trial establishes that CNDO-109-NK cells generated from related HLA haploidentical donors, cryopreserved, and then safely administered to AML patients with transient persistence without exogenous cytokine support. Three durable complete remissions of 32.6 to 47.6+ months were observed, suggesting additional clinical investigation of CNDO-109-NK cells for patients with myeloid malignancies, alone or in combination with additional immunotherapy strategies, is warranted. PMID- 29597003 TI - Prenatal and postnatal cigarette and cannabis exposure: Effects on Secretory Immunoglobulin A in early childhood. AB - AIMS: Secretory Immunoglobulin A (SIgA) plays a critical role in immune functioning by preventing pathogens from adhering to epithelial mucosa. Most infectious agents enter the body via mucosal surfaces, thus SIgA serves in the defense against respiratory, intestinal, and urinogenitary infections, as well as periodontal disease and caries. This study examined the possibility that pre- and postnatal exposure to cigarette and cannabis is associated with individual differences in Secretory Immunoglobulin A (SIgA) levels in early childhood. METHODS: Participants were 50 mother/infant (29 boys; 35% Caucasian) dyads recruited at their first prenatal appointment in a large northeastern community hospital in the United States. Repeated assessments of pre- and postnatal cigarette and cannabis were conducted beginning in the first trimester of pregnancy, using multiple methods (i.e., saliva, meconium, self-report). Infants were grouped into those prenatally exposed to either cigarette only (n = 19), cigarette and cannabis (n = 19), or with no prenatal substance exposure (n = 12). At age 5 years, the children's saliva was collected and assayed for SIgA. RESULTS: There were group differences in SIgA levels as a function of prenatal exposure to cigarette and cannabis - children in the cigarette only and the cigarette and cannabis groups had higher SIgA levels compared to the non-exposed children. Children who experienced the combination of postnatal exposure to cigarette and cannabis had higher levels of SIgA, even after accounting for prenatal exposures and other covariates relevant to immune system functioning. CONCLUSIONS: Prenatal and postnatal exposure to cigarette and cannabis may be associated with hyperactivity of mucosal immunity in early childhood. Links between cigarette and cannabis exposure and health problems in early childhood may be partially explained by prenatal and postnatal exposure-related changes in mucosal immunity. PMID- 29597004 TI - Neuroprotective effect of docosahexaenoic acid in rat traumatic brain injury model via regulation of TLR4/NF-Kappa B signaling pathway. AB - OBJECTIVE: The experiments were conducted to prove that docosahexaenoic acid (DHA) alleviates traumatic brain injury (TBI) through regulating TLR4/NF-Kappa B signaling pathway. METHODS: Bioinformatic analysis was performed using published data from Gene Expression Omnibus (GEO) database to investigate differentially expressed genes and signaling pathways. Controlled cortical impact (CCI) injury rat model was built, and DHA (16 mg/kg in DMSO, once each day) was used to treat TBI rats. Neurological severity score (NSS) and beam walking test and rotarod test were used to confirm whether DHA is neuron-protective against TBI. The expression of TLR4, NF-Kappa B p65, (TNF)-alpha and IL-1beta were examined by qRT PCR and western blot. The impact of DHA on neurocyte apoptosis was validated by TdT-mediated dUTP Nick-End Labeling (TUNEL) staining. The influence of DHA on CD11b and GFAP expression in the hippocampus was determined through immunohistochemical analysis. RESULTS: TLR4/NF Kappa B pathway was suggested to be closely correlated with TBI by bioinformatic analysis. DHA could improve the neurological function and learning and memory ability of rats after TBI as well as promote neurocytes from apoptosis. TLR4 expression and the expression of inflammatory mediator NF-Kappa B were also repressed by DHA treatment. CONCLUSIONS: DHA exerted a neuron-protective influence in a rat model of TBI via repressing TLR4/NF-Kappa B pathway. PMID- 29597005 TI - Non-syndromic retinitis pigmentosa. AB - Retinitis pigmentosa (RP) encompasses a group of inherited retinal dystrophies characterized by the primary degeneration of rod and cone photoreceptors. RP is a leading cause of visual disability, with a worldwide prevalence of 1:4000. Although the majority of RP cases are non-syndromic, 20-30% of patients with RP also have an associated non-ocular condition. RP typically manifests with night blindness in adolescence, followed by concentric visual field loss, reflecting the principal dysfunction of rod photoreceptors; central vision loss occurs later in life due to cone dysfunction. Photoreceptor function measured with an electroretinogram is markedly reduced or even absent. Optical coherence tomography (OCT) and fundus autofluorescence (FAF) imaging show a progressive loss of outer retinal layers and altered lipofuscin distribution in a characteristic pattern. Over the past three decades, a vast number of disease causing variants in more than 80 genes have been associated with non-syndromic RP. The wide heterogeneity of RP makes it challenging to describe the clinical findings and pathogenesis. In this review, we provide a comprehensive overview of the clinical characteristics of RP specific to genetically defined patient subsets. We supply a unique atlas with color fundus photographs of most RP subtypes, and we discuss the relevant considerations with respect to differential diagnoses. In addition, we discuss the genes involved in the pathogenesis of RP, as well as the retinal processes that are affected by pathogenic mutations in these genes. Finally, we review management strategies for patients with RP, including counseling, visual rehabilitation, and current and emerging therapeutic options. PMID- 29597007 TI - Design and Rationale for the Veterans Affairs "Cooperative Study Program 594 Comparative Effectiveness in Gout: Allopurinol vs. Febuxostat" Trial. AB - BACKGROUND: Gout patients do not routinely achieve optimal outcomes related in part to suboptimal administration of urate lowering therapy (ULT) including first line xanthine oxidase inhibitors allopurinol or febuxostat. Studies leading to the approval of febuxostat compared this agent to allopurinol in inappropriately low, fixed doses. We will compare allopurinol with febuxostat in gout using appropriately titrated doses of both agents and a "treat-to-target" strategy congruent with specialty guidelines. METHODS: We have planned and initiated the Veterans Affairs (VA) Cooperative Study Program (CSP) 594, Comparative Effectiveness in Gout: Allopurinol vs Febuxostat study. This large double-blind, non-inferiority trial will enroll 950 gout patients randomized to receive allopurinol or febuxostat. Patients will be followed for a total of 72 weeks encompassing 3 distinct 24-week study phases. During Phase I (0-24 weeks), participants will undergo gradual dose titration of ULT until achievement of serum uric acid (sUA) <6.0 mg/dL or <5.0 mg/dL if tophi are present. Dose escalation will not be allowed during final three study visits of Phase 2 (24-48 weeks) and during Phase 3 (48-72 weeks). The primary study outcome is the proportion of participants experiencing at least one gout flare during Phase 3. Subsequent to the 72-week study, participants will be followed passively for up to 10 years after the study to assess long-term health outcomes. CONCLUSION: With its completion, the VA Comparative Effectiveness in Gout: Allopurinol vs Febuxostat study will demonstrate the central role of gradual ULT dose escalation and a treat-to-target strategy in gout management. PMID- 29597006 TI - Rationale and study protocol for Unidas por la Vida (United for Life): A dyadic weight-loss intervention for high-risk Latina mothers and their adult daughters. AB - BACKGROUND: Half of Mexican-American women are under-active and nearly 78% are overweight/obese. The high lifetime risk of developing type 2 diabetes necessitates a culturally appropriate lifestyle intervention. PURPOSE: Unidas por la Vida is a novel dyadic intervention that capitalizes on the centrality of family in Latino culture to mobilize an existing family dyad as a resource for health behavior change. The intervention aims to improve health behaviors and promote weight loss in two at-risk members of the same family: mothers with type 2 diabetes and their overweight/obese adult daughters who are at risk for developing diabetes. METHODS: Participants (N = 460 mother-adult daughter dyads) will be randomized into one of three conditions: 1) dyadic participation (mothers daughters) in a lifestyle intervention; 2) individual participation (mothers alone; unrelated daughters alone) in a lifestyle intervention; and 3) mother daughter dyads in a minimal intervention control group. RESULTS: The primary outcome is weight loss. Secondary outcomes include physical activity, dietary intake, physiological measures (e.g. HbA1c), and body composition. Both the dyadic and individual interventions are expected to produce greater weight loss at 6, 12, and 18 months than those in minimal intervention control group, with women assigned to the dyadic intervention expected to lose more weight and to maintain the weight loss longer than women assigned to the individual intervention. CONCLUSION: Because health risks are often shared by multiple members of at-risk families, culturally appropriate, dyadic interventions have the potential to increase the success of behavior change efforts and to extend their reach to multiple family members. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02741037. PMID- 29597008 TI - Buccal venom gland associates with increased of diversification rate in the fang blenny fish Meiacanthus (Blenniidae; Teleostei). AB - At the macroevolutionary level, many mechanisms have been proposed to explain explosive species diversification. Among them morphological and/or physiological novelty is considered to have a great impact on the tempo and the mode of diversification. Meiacanthus is a genus of Blenniidae possessing a unique buccal venom gland at the base of an elongated canine tooth. This unusual trait has been hypothesized to aid escape from predation and thus potentially play an important role in their pattern of diversification. Here, we produce the first time calibrated phylogeny of Blenniidae and we test the impact of two morphological novelties on their diversification, i.e. the presence of swim bladder and buccal venom gland, using various comparative methods. We found an increase in the tempo of lineage diversification at the root of the Meiacanthus clade, associated with the evolution of the buccal venom gland, but not the swim bladder. Neither morphological novelty was associated with the pattern of size disparification in blennies. Our results support the hypothesis that the buccal venom gland has contributed to the explosive diversification of Meiacanthus, but further analyses are needed to fully understand the factors sustaining this burst of speciation. PMID- 29597009 TI - MicroRNA528 Affects Lodging Resistance of Maize by Regulating Lignin Biosynthesis under Nitrogen-Luxury Conditions. AB - Lodging under nitrogen (N)-luxury conditions substantially reduces crop yield and seed quality. However, the molecular mechanisms of plant lodging resistance remain largely unclear, especially in maize. We report here that the expression of ZmmiR528, a monocot-specific microRNA, is induced by N luxury but reduced by N deficiency. We show by the thioacidolysis and acetyl bromide analysis that N luxury significantly reduces the generation of H, G, and S monomers of the lignin as well as its total content in maize shoots. We further demonstrate that ZmLACCASE3 (ZmLAC3) and ZmLACCASE5 (ZmLAC5), which encode the copper-containing laccases, are the targets of ZmmiR528. In situ hybridization showed that ZmmiR528 is mainly expressed in maize vascular tissues. Knockdown of ZmmiR528 or overexpression of ZmLAC3 significantly increased the lignin content and rind penetrometer resistance of maize stems. In contrast, transgenic maize plants overexpressing ZmmiR528 had reduced lignin content and rind penetrometer resistance and were prone to lodging under N-luxury conditions. RNA-sequencing analysis revealed that ZmPAL7 and ZmPAL8 are upregulated in transgenic maize lines downregulating ZmmiR528. Under N-luxury conditions, the expression levels of ZmPALs were much higher in ZmmiR528-knockdown lines than in the wild type and transgenic maize lines overexpressing ZmmiR528. Taken together, these results indicate that, by regulating the expression of ZmLAC3 and ZmLAC5, ZmmiR528 affects maize lodging resistance under N-luxury conditions. PMID- 29597010 TI - Boston keratoprosthesis type 1 for limbal stem cell deficiency after severe chemical corneal injury: A systematic review. AB - PURPOSE: To systematically review the published literature on outcomes of Boston keratoprosthesis type 1 for the treatment of limbal stem cell deficiency secondary to severe chemical corneal injury. METHODS: Literature searches were conducted in MEDLINE (Ovid), Embase, Web of Science, and the Cochrane Central Register. The main outcome measures assessed were the proportion of eyes with best-corrected visual acuity (BCVA) >= 20/200 and the proportion retaining their original keratoprosthesis, both at the last recorded visit. RESULTS: We identified 9 reports in which outcomes of Boston keratoprosthesis type I implantation after severe chemical injury could be determined, encompassing a total of 106 eyes of 100 patients. There were no randomized controlled studies. The median pre-operative BCVA was hand motion. Vision improved to >=20/200 in 99/106 (93.4%) eyes after implantation. With a mean follow-up of 24.99 +/- 14 months, 68/106 (64.1%) eyes retained BCVA >= 20/200 at the last examination. Therefore, 68/99 (68.7%) of those who improved to > 20/200 maintained at least this acuity. The originally implanted device was retained in 88/99 (88.9%) recipients for whom retention was reported. The mean time to failure was 22.36 +/ 17.2 months. Glaucomatous optic neuropathy was the most common cause for BCVA <20/200 in eyes that retained the keratoprosthesis (18/27, 66.7%).. CONCLUSIONS: Implantation of a Boston keratoprosthesis type I in eyes with corneal blindness after severe chemical ocular injury leads to functional vision in the majority of recipients. Evidence was limited by variability in outcome reporting and an absence of controlled studies.. PMID- 29597011 TI - Quantitative multiplexed profiling of Penicillium funiculosum secretome grown on polymeric cellulase inducers and glucose. AB - : Filamentous fungi respond to the need to secure utilisable carbon from their growth milieu by secreting unique extracellular proteins depending upon the types of polymeric substrates. We have here profiled the variations in the secretome pattern of a non-model hypercellulolytic fungus - Penicillium funiculosum, grown in minimal media containing four different polymeric cellulase inducers, i.e., Avicel, wheat bran, ammonium-pretreated wheat straw and Avicel & wheat bran, and glucose over its early and late log phases of growth. Of the 137 secreted proteins validated at 1% FDR, we identified the quantified proteins in three clusters as early, persistently or lately expressed. The type of carbon substrate present in the culture media significantly affected the levels of cellulolytic enzymes expression by the fungus. The top abundant proteins quantified in the secretome for Avicel and wheat bran were cellobiohydrolaseI [GH7-CBM1], cellobiohydrolaseII [GH6-CBM1], beta-glucosidase [GH3], arabinofuranosidase [GH51] and beta-xylosidase [GH3], with bicupin being highest in case of wheat straw. Our results further suggested that the fungus secreted the extracellular proteins in waves, such that the initial responders act to hydrolyse the composite substrates in the culture environment before the second wave of proteins which tend to be more tailored to the specific substrate in the cultivating media. BIOLOGICAL SIGNIFICANCE: In this article, we have comprehensively examined the dynamics of the secretome of a non-model hypercellulolytic fungus produced in response to model and composite cellulase inducers. Our study has provided additional insights into how the fungus enzyme machinery responds to the presence of different polymeric cellulase inducers over the two different growth phases (early growth and late growth phase). The comprehensive typing and quantification of the different proteins present in the secretomes of the cellulolytic fungal strains in response to diverse nutrient sources hold many prospects in understanding the fungus unique enzyme machinery and dynamics for the downstream biotechnological applications. PMID- 29597012 TI - Differential expression of gonadotropin and estrogen receptors and oocyte cytology during follicular maturation associated with egg viability in European eel (Anguilla anguilla). AB - In captivity, oogenesis and ovarian follicle maturation in European eel can be induced experimentally using hormonal therapy. The follicle's ability to respond effectively to the induction of maturation and ovulation, resulting in viable eggs, depends on the oocyte stage at the time of induction. We hypothesized that variation in the expression of key hormone receptors in the ovary and size of oocyte lipid droplets are associated with changes in oocyte stage. Thus, we induced ovarian follicle maturation using a priming dose of fish pituitary extract followed by the administration of a 17alpha, 20beta-dihydroxy-4-pregnen-3 one (DHP) injection. Females were then strip-spawned, the eggs were fertilized in vitro, incubated and larval survival was recorded at 3 days post hatch (dph). The expression of gonadotropin receptors (fshr, lhcgr1 and lhcgr2) and estrogen receptors (esr1, esr2a, esr2b, gpera and gperb) was quantified and the size of oocyte lipid droplets measured. Larval survival at 3 dph was used to differentiate high- and low-quality egg batches. Results showed significantly higher abundance of lhcgr1 and esr2a at priming for high-quality egg batches whereas fshr and gperb transcripts were significantly higher at DHP injection for low-quality egg batches. Therefore, high levels of lhcgr1 and esr2a may be important for attaining follicular maturational competence, while high fshr and gperb mRNA levels may indicate inadequate maturational competence. Furthermore, lipid droplet size at DHP and in ovulated eggs was significantly smaller in high quality egg batches than in low-quality, which indicates that droplet size may be a useful marker of follicular maturational stage. PMID- 29597013 TI - A new telemetry-based system for assessing cardiovascular function in group housed large animals. Taking the 3Rs to a new level with the evaluation of remote measurement via cloud data transmission. AB - INTRODUCTION: A newly developed total implant telemetry system for cardiovascular (CV), electrophysiological and body temperature measurement was evaluated. A cloud-based transmission of the physiological signals allowed an assessment of the quality of the physiological signals despite the physical separation between the instrumented animals and the evaluating home laboratory. The new system is intended to be used for safety pharmacological evaluations of drug candidates in various species. METHODS: Two female minipigs, 6 Labrador-mixed breed dogs and 4 female Cynomolgus monkeys were instrumented with a newly developed total implant system (TSE SYSTEMS). The implants feature a microprocessor, internal memory (1 GB), 2 solid state pressure-tipped catheters, amplifiers and a radio transmitter. Sampling rates for each measurement can be selected within a range between 0.1 and 1 kHz. Biological signals are selected in a programmable fashion on a session by-session basis according to a user-defined protocol. The pressure sensors are at the tip of an electrical lead having a length customized to each species. Core temperature measurement and activity monitoring (3D accelerometer) are included in the system. Digital transmission range using a single antenna is 5 m with up to 16 animals held together and monitored simultaneously. The range can be expanded with more antennas in an array coupled to a single receiver. The antenna/receiver station consists of a single USB powered mobile unit connected to a PC or laptop. The battery life provides 110 days of continuous recording. The dogs and minipigs were instrumented and monitored in Germany. A novel cloud based data transmission system was developed to monitor the physiological signals in real-time from the Cynomolgus monkeys, still kept in Mauritius, from the data evaluation laboratory in Germany. After recovery from the surgical implantation, aortic pressure (AP), left ventricular pressure (LVP), ECG and body temperature were recorded for 24 hr monitoring sessions in all animals. Additionally, moxifloxacin (10, 30 and 100 mg/kg) was tested in the dog model using a modified Latin square cross-over study design. RESULTS: The implant was well tolerated and the animals recovered rapidly from the implantation procedure. Excellent signal quality was obtained and stable hemodynamic and electrophysiological parameters could be measured, with little signal artefact or drop-out, over 24 h in each species. After oral dosing of moxifloxacin to the dogs, a substantial, dose dependent increase in the QT-interval duration could be shown, as anticipated for this agent. Cloud-based data acquisition from the animals in Mauritius and the data evaluation lab in Germany worked well. CONCLUSION: This new CV telemetry system provides a novel alternative to fluid-filled catheter telemetry systems and the coupling to a cloud-based data transmission allows for flexibility in the location of the instrumented animals and data acquisition and the location of the site for data analysis. For the first time it is technically feasible to conduct a CV safety pharmacology study in Cynomolgus monkeys without having to ship them long distances to the home laboratory. PMID- 29597014 TI - Fatigue in Parkinson's disease: Metric properties of the fatigue impact scale for daily use (D-FIS), and its impact on quality of life. AB - OBJECTIVE: In Parkinson's disease patients, fatigue is a disabling non-motor symptom whose prevalence ranges from 28% to 58%. The Fatigue Impact Scale for Daily Use (D-FIS), one of the various scales for quantifying fatigue. The aim of our study was to analyze the metric properties of the D-FIS in PD subjects and assess the impact of fatigue on their quality of life. PATIENTS AND METHODS: The cohort in this study was comprised of 211 consecutive patients with a PD diagnosis regularly followed up at the Movement Disorders Unit of the Neurology Department at Carlos Andrade Marin Hospital (HCAM) in Quito, Ecuador, according to the United Kingdom PD Society Brain Bank criteria. Data Quality, Acceptability, Reliability, Stability (test-retest), Validity and Multiple linear regression analysis were determined. RESULTS: The final sample consisted of 138 men (65.4%) and 73 women. Forty-six percent of these (98 patients) were in stage II of H&Y. We obtained a Cronbach's alpha value of 0.912 and an ICC value of 0.79. D-FIS was strongly correlated with depression (Spearman rho [Srho] 0.60), anxiety (Srho 0.59), quality of life (Srho 0.67), and non-motor symptoms (Srho 0.66). The scale's discriminant validity, assessed among the different stages of H&Y by the Kruskal-Wallis test, showed major significance (X2 = 23.183, p <= 0.001). In the Multiple linear regression study, the resulting model proves that fatigue has a determining effect on quality of life. CONCLUSIONS: The D-FIS has good metric properties and demonstrates that fatigue significantly affects PD patients' quality of life and that its impact is independent from that of anxiety, depression, and sleep disorders. PMID- 29597015 TI - Evaluation of Olfactory Outcome After Frontolateral Approach for Treatment of Suprasellar Tumors. AB - OBJECTIVE: We present the findings of our prospective study assessing olfactory function outcome in patients undergoing a frontolateral approach for the resection of suprasellar lesions. METHODS: Eighteen consecutive patients (7 females, 11 males) surgically treated at our institute for suprasellar tumors were included in this prospective study. Olfactory function was evaluated at the admission and 14 days after the surgery using the standard 12-item "Sniffin' Sticks" screening (SSS) test. The olfactory outcome was correlated to the following variables: tumor type, size, consistency, and extent of vertical and lateral growth. RESULTS: Preoperative and postoperative SSS test mean values were, respectively, 9.11 and 8.72 (not significant: P = 0.274). In only 1 case (5%), with larger suprasellar extension, the difference between preoperative and postoperative SSS was >=3 (reduction of 5 points). At the subjective evaluation, no patient stated a deficit in smelling. CONCLUSION: The frontolateral craniotomy is a minimally invasive route to treat suprasellar tumors and has a low approach related morbidity. It allows tumor resection with low risk for the olfactory function. A risk factor for postoperative olfactory deficit could be significant brain retraction. PMID- 29597016 TI - A Cohort Study of the Natural History of Odontoid Pseudoarthrosis Managed Nonoperatively in Elderly Patients. AB - OBJECTIVE: Although the primary goal of treatment of type II odontoid fracture is bony union, some advocate continued nonsurgical management of minimally symptomatic older patients who have fibrous union or minimal fracture motion. The risk of this strategy is unknown. We reviewed our long-term outcomes after dens nonunion to define the natural history of Type II odontoid fractures in elderly patients managed nonoperatively. METHODS: A retrospective chart review of 50 consecutive adults aged 65 or older with Type II odontoid fracture initially managed nonsurgically from 1998 to 2012 at a single tertiary care institution was conducted. Particular attention was paid to patients who had orthosis removal despite absent bony fusion. Patients were contacted prospectively by telephone and followed until death, surgical intervention, or last known contact. RESULTS: Fifty patients initially were managed nonsurgically; of these, 21 (42.0%) proceeded to bony fusion, 3 (6%) underwent delayed surgery for persistent instability, and 26 (52%) had orthosis removal despite the lack of solid arthrodesis on imaging. The last group had a median follow-up of 25 months (range 4-158 months), with 20 of 26 (76.9%) followed until death. Of these patients, 1 patient developed progressive quadriplegia and dysphagia 11 months after initial injury. Compared with patients with spontaneous union, patients with nonunion had shorter life expectancy, despite no significant differences between the groups with respect to age, sex, injury mechanism, radiographic variables, or follow-up duration. CONCLUSIONS: Orthosis removal despite fracture nonunion may be reasonable in elderly patients with Type II dens fractures. PMID- 29597017 TI - Enlarging Temporal Arachnoid Cyst Extending Inside the Sphenoid Sinus. AB - BACKGROUND: Cerebral arachnoid cysts that eroded the skull base and extended into the paranasal sinus are very rare with only a few cases reported. CASE DESCRIPTION: A 71-year-old woman with history of headache for 4 years was evaluated because of an enlarging right temporal cystic lesion with evidence of resorption of the greater wing of the sphenoid bone and a fluid-filled sphenoid sinus. For 3 years, the cerebral cyst remained stable and minimally symptomatic. On her last magnetic resonance imaging, the cyst enlarged and perilesional edema was identified. The patient was treated with an open intracranial approach to explore the cyst. An arachnoid cyst was found which extended into the sphenoid sinus through a defect in the temporal fossa floor. The skull base defect was repaired using a muscle plug and fibrin sealant to obliterate the dural and bony defect. The arachnoid cyst was fenestrated to the basal cisterns. CONCLUSIONS: Cerebral arachnoid cysts extending into the paranasal sinuses are very rare presenting mostly with rhinorrhea and nasal symptoms. Patients with neurologic symptoms may need intracranial surgery to fenestrate the cyst. Obliteration of the fistula into the paranasal sinus is essential to prevent further complications. PMID- 29597018 TI - Rare Event Captured with Intracranial Pressure Monitor: Malignant Spike in Intracranial Pressure During Delayed Chest Closure in Heart-Transplant Patient with Ischemic Stroke. AB - BACKGROUND: Patients with open chest wounds, either related to trauma or cardiothoracic procedures, are subjected to significant physiologic alterations when undergoing chest wound closure. Sudden increased intrathoracic pressure at closure decreases venous return from the brain to the heart; consequently the total blood volume in the ridged skull increases, resulting in increased intracranial pressure (ICP). Patients with intact cerebrovascular autoregulation can compensate for these sudden changes by adjusting cerebral blood flow to maintain physiologic ICP. In cases where the autoregulatory mechanisms are compromised, such as stroke or trauma, the ICP can become pathologically elevated. If the patient does not have an ICP monitor, the spike in ICP can go unrecognized, compromising cerebral perfusion pressure and resulting in increased morbidity and mortality. CASE DESCRIPTION: Herein we describe a case of pathologic elevations in ICP captured with an ICP monitor at the time of chest wound closure in a patient with delayed chest wound closure after orthotopic heart transplant and comorbid embolic stroke. CONCLUSIONS: This case report demonstrates the potential utility of ICP monitoring in patients with impaired cerebrovascular autoregulation with open and manipulated chest wounds from transplant or trauma. PMID- 29597019 TI - Quantitative Evaluation of Compressed L4-5 and S1 Nerve Roots of Lumbar Disc Herniation Patients by Diffusion Tensor Imaging and Fiber Tractography. AB - OBJECTIVE: To delineate fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of compressed nerve roots in patients with lumbar disc herniation by diffusion tensor imaging and fiber bundle tracing and investigate the relationship between FA and ADC values and Swiss Spinal Stenosis Questionnaire and visual analog scale scores. METHODS: Twenty patients with lumbar disc herniation and 20 age- and sex-matched healthy volunteers were assessed using the Swiss Spinal Stenosis Questionnaire and visual analog scale. All subjects underwent conventional sagittal T1-weighted and T2-weighted magnetic resonance imaging, axial T2-weighted imaging, and diffusion tensor imaging and fiber tractography. RESULTS: In 20 patients with lumbar disc herniation, there were 31 nerve roots involved (9/31 L4, 15/31 L5, and 7/31 S1). Mean Swiss Spinal Stenosis Questionnaire scores of patients were 53.55% +/- 11.91%, and mean visual analog scale scores were 5.96 +/- 1.64. FA values of lumbar nerve roots were 0.332 +/- 0.014 in healthy volunteers. FA values of compressed lumbar nerve roots were 0.251 +/- 0.022, significantly lower than FA values of contralateral noncompressed nerve roots and lumbar nerve roots of healthy volunteers. ADC values of lumbar nerve roots were 1.763 +/- 0.075 in healthy volunteers. ADC values of compressed lumbar nerve roots were 2.090 +/- 0.078, significantly higher than ADC values of contralateral noncompressed nerve roots and lumbar nerve roots of healthy volunteers. CONCLUSIONS: Fiber tractography is capable of delineating microstructural changes of lumbosacral nerve roots, and radiculopathy in lumbar disc herniation is associated with significant changes in FA and ADC values.

AB - BACKGROUND: Preserving functionality is important during neurosurgical resection of brain tumors. Specialized centers also map further brain functions apart from motor and language functions, such as arithmetic processing (AP). The mapping of AP by navigated repetitive transcranial magnetic stimulation (nrTMS) in healthy volunteers has been reported. OBJECTIVE: The present study aimed to correlate the results of mapping AP with functional patient outcomes. METHODS: We included 26 patients with parietal brain tumors. Because of preoperative impairment of AP, mapping was not possible in 8 patients (31%). We stimulated 52 cortical sites by nrTMS while patients performed a calculation task. Preoperatively and postoperatively, patients underwent a standardized number-processing and calculation test (NPCT). Tumor resection was blinded to nrTMS results, and the change in NPCT performance was correlated to resected AP-positive spots as identified by nrTMS. RESULTS: The resection of AP-positive sites correlated with a worsening of the postoperative NPCT result in 12 cases. In 3 cases, no AP positive sites were resected and the postoperative NPCT result was similar to or better than preoperatively. Also, in 3 cases, the postoperative NPCT result was better than preoperatively, although AP-positive sites were resected. CONCLUSIONS: Despite presenting only a few cases, nrTMS might be a useful tool for preoperative mapping of AP. However, the reliability of the present results has to be evaluated in a larger series and by intraoperative mapping data. PMID- 29597022 TI - Design and preparation of bi-functionalized short-chain modified zwitterionic nanoparticles. AB - : An ideal nanomaterial for use in the bio-medical field should have a distinctive surface capable of effectively preventing nonspecific protein adsorption and identifying target bio-molecules. Recently, the short-chain zwitterion strategy has been suggested as a simple and novel approach to create outstanding anti-fouling surfaces. In this paper, the carboxyl end group of short chain zwitterion-coated silica nanoparticles (SiO2-ZWS) was found to be difficult to functionalize via a conventional EDC/NHS strategy due to its rapid hydrolysis side-reactions. Hence, a series of bi-functionalized silica nanoparticles (SiO2 ZWS/COOH) were designed and prepared by controlling the molar ratio of 3 aminopropyltriethoxysilane (APTES) to short-chain zwitterionic organosiloxane (ZWS) in order to achieve above goal. The synthesized SiO2-ZWS/COOH had similar excellent anti-fouling properties compared with SiO2-ZWS, even in 50% fetal bovine serum characterized by DLS and turbidimetric titration. Subsequently, SiO2 ZWS/COOH5/1 was chosen as a representative and then demonstrated higher detection signal intensity and more superior signal-to-noise ratios compare with the pure SiO2-COOH when they were used as a bio-carrier for chemiluminescence enzyme immunoassay (CLEIA). These unique bi-functionalized silica nanoparticles have many potential applications in the diagnostic and therapeutic fields. STATEMENT OF SIGNIFICANCE: Reducing nonspecific protein adsorption and enhancing the immobilized efficiency of specific bio-probes are two of the most important issues for bio-carriers, particularly for a nanoparticle based bio-carrier. Herein, we designed and prepared a bi-functional nanoparticle with anti-fouling property and bio conjugation capacity for further bioassay by improving the short chain zwitterionic modification strategy we have proposed previously. The heterogeneous surface of this nanoparticle showed effective anti-fouling properties both in model protein solutions and fetal bovine serum (FBS). The modified nanoparticles can also be successfully functionalized with a specific antibody for CLEIA assay with a prominent bio-detection performance even in 50% FBS. In this paper, we also investigated an unexpectedly fast hydrolysis behavior of NHS-activated carboxylic groups within the pure short-chain zwitterionic molecule that led to no protein binding in the short-chain zwitterion modified nanoparticle. Our findings pave a new way for the designing of high performance bio-carriers, demonstrating their strong potential as a robust platform for diagnosis and therapy. PMID- 29597020 TI - A Novel Knotless Barbed Suture Technique for Traumatic Thoracolumbar Fracture in Posterior Surgery. AB - BACKGROUND: Surgical wound closure directly influences spinal surgical efficiency and several postoperative complications. The traditional suture technique is time consuming and associated with greater rates of complications. Bidirectional absorbable barbed sutures seem to compensate for some of the limitations of traditional suture; however, they rarely are reported in spinal surgery. We designed a novel suture technique for use in thoracolumbar spinal surgery. METHODS: The data of 189 patients with traumatic thoracolumbar fractures were analyzed between bidirectional barbed suture closure and traditional interrupted suture closure. Data of operative time, wound closure time, length of incision, intraoperative blood loss, complications of wound dehiscence and postoperative hematoma, cost, and neurologic status were collected. RESULTS: No significant differences were observed in the baseline demographics of included patients. Compared with the traditional suturing group, the barbed sutures decreased the mean operative time (P = 0.037), suture time (P < 0.01), and mean suturing time (P < 0.01) significantly, although no statistically significant differences were found in blood loss (P = 0.724) and neurologic functional scores (preoperative: P = 0.901; 3 months after surgery: P = 0.208; final follow-up assessments: P = 0.163), and no statistically significant differences were found in rates of postoperative infection, hematoma, and wound dehiscence. CONCLUSIONS: Our findings suggest that the novel knotless barbed suture has comparable strength to traditional sutures, with the advantage of less suturing time. It is an efficient, safe technique, and alternative choice for patients with thoracolumbar fracture after posterior surgery. PMID- 29597023 TI - Impact of nitinol stent surface processing on in-vivo nickel release and biological response. AB - : Although nitinol is widely used in percutaneous cardiovascular interventions, a causal relationship between nickel released from implanted cardiovascular devices and adverse systemic or local biological responses has not been established. The objective of this study was to investigate the relationship between nitinol surface processing, in-vivo nickel release, and biocompatibility. Nitinol stents manufactured using select surface treatments were implanted into the iliac arteries of minipigs for 6 months. Clinical chemistry profile, complete blood count, serum and urine nickel analyses were performed periodically during the implantation period. After explant, stented arteries were either digested and analyzed for local nickel concentration or fixed and sectioned for histopathological analysis of stenosis and inflammation within the artery. The results indicated that markers for liver and kidney function were not different than baseline values throughout 180 days of implantation regardless of surface finish. In addition, white blood cell, red blood cell, and platelet counts were similar to baseline values for all surface finishes. Systemic nickel concentrations in serum and urine were not significantly different between processing groups and comparable to baseline values during 180 days of implantation. However, stents with non-optimized surface finishing had significantly greater nickel levels in the surrounding artery compared to polished stents. These stents had increased stenosis with potential for local inflammation compared to polished stents. These findings demonstrate that proper polishing of nitinol surfaces can reduce in-vivo nickel release locally, which may aid in minimizing adverse inflammatory reactions and restenosis. STATEMENT OF SIGNIFICANCE: Nitinol is a commonly used material in cardiovascular medical devices. However, relationships between nitinol surface finishing, in-vivo metal ion release, and adverse biological responses have yet to be established. We addressed this knowledge gap by implanting single and overlapped nitinol stents with different surface finishes to assess systemic impact on minipigs (i.e. serum and urine nickel levels, liver and kidney function, immune and blood count) over the 6 month implantation period. In addition, nickel levels and histopathology in stented arteries were analyzed on explant to determine relationships between surface processing and local adverse tissue reactions. The findings presented here highlight the importance of surface processing on in-vivo nickel release and subsequent impact on local biological response for nitinol implants. PMID- 29597025 TI - Stromal cell-derived factor-1alpha-encapsulated albumin/heparin nanoparticles for induced stem cell migration and intervertebral disc regeneration in vivo. AB - : Intervertebral disc (IVD) degeneration may cause many diseases and pain. Stem cell migration toward the site of IVD degeneration is a key factor for IVD regeneration. In the current study, we prepared albumin/heparin nanoparticles (BHNPs) as injectable carriers of stromal cell-derived factor-1alpha (SDF-1alpha, also known as C-X-C motif chemokine 12), a powerful chemoattractant for the homing of bone marrow resident mesenchymal stem cells (MSCs), for protection of the molecule against degradation for a sustained release. The NPs have relatively uniform small size, with a diameter of about 110 nm. The NPs possess a high loading capacity of SDF-1alpha with a sustained release profile. The bioactivity of the obtained BHNPs/SDF was then studied in vitro and in vivo. The BHNPs/SDF can induce migration of MSCs in a dose-dependent manner in vitro. After injected into the damaged disc, BHNPs/SDF induce much better regeneration of annulus fibrosus and nucleus pulposus, compared to SDF-1alpha and BHNPs alone, evidenced with better histological grade scores and higher expression of SOX9, Aggrecan, and Collagen type II at the level of both mRNA and protein. This study provides a simple nanoplatform to load SDF-1alpha and protect it against degradation, with potential application in inductive tissue regeneration in vivo. STATEMENT OF SIGNIFICANCE: Stem cell migration toward the site of IVD degeneration is a key event to promote IVD regeneration. In the current study, we prepared albumin/heparin nanoparticles (BHNPs) as injectable carriers to protect SDF 1alpha against degradation and for the sustained release of the molecule. After injected into the damaged disc, BHNPs/SDF induced much better regeneration of IVD, compared to SDF-1alpha and BHNPs alone. This study provides a simple nanoplatform to load SDF-1alpha and protect it from degradation, with potential application in inductive tissue regeneration in vivo. PMID- 29597024 TI - Design of hydrogels to stabilize and enhance bone morphogenetic protein activity by heparin mimetics. AB - : Although bone morphogenetic protein-2 (BMP-2) is known to be the most potent stimulator available for bone formation, a major barrier to widespread clinical use is its inherent instability and absence of an adequate delivery system. Heparin is being widely used in controlled release systems due to its strong binding ability and protective effect for many growth factor proteins. In this work, we developed a hydrogel surface that can mimic heparin to stabilize BMP-2 and to enhance osteogenesis by introducing heparin-mimicking sulfonated molecules such as poly-vinylsulfonic acid (PVSA) or poly-4-styrenesulfonic acid (PSS), into photo-crosslinkable hydrogel. Bioactivity of BMP-2 was well preserved in the presence of polysulfonates during exposure to various therapeutically relevant stressors. The heparin-mimicking sulfonated hydrogels were effective to bind BMP 2 compared to unmodified MeGC hydrogel and significantly enhanced osteogenic differentiation of encapsulated bone marrow stromal cells (BMSCs) without the addition of exogenous BMP-2. The sulfonated hydrogels were effective in delivering exogenous BMP-2 with reduced initial burst and increased BMSCs osteogenesis induced by BMP-2. These findings suggest a novel hydrogel platform for sequestering and stabilizing BMP-2 to enhance osteoinductive activity in bone tissue engineering. STATEMENT OF SIGNIFICANCE: Although bone morphogenetic protein-2 (BMP-2) is believed to be the most potent cytokine for bone regeneration, its clinical applications require supraphysiological BMP dosage due to its intrinsic instability and fast enzymatic degradation, leading to worrisome side effects. This study demonstrates a novel hydrogel platform that mimics a natural protector of BMPs, heparin, to sequester and stabilize BMP-2 for increased osteoinductive signaling. This study will achieve the stabilization of BMPs with prolonged bioactivity by a synthetic heparin mimic that has not been examined previously. Moreover, the heparin mimetic hydrogel surface can augment endogenous BMP activity by sequestering and localizing the cell-produced BMPs. The additional knowledge gained from this study may suggest basis for future development of material-based therapeutics for tissue engineering. PMID- 29597026 TI - Adhesive gland transcriptomics uncovers a diversity of genes involved in glue formation in marine tube-building polychaetes. AB - : Tube-building sabellariid polychaetes are hermatypic organisms capable of forming vast reefs in highly turbulent marine habitats. Sabellariid worms assemble their tube by gluing together siliceous and calcareous clastic particles using a polyelectrolytic biocement. Here, we performed transcriptomic analyses to investigate the genes that are differentially expressed in the parathorax region, which contains the adhesive gland and tissues, from the rest of the body. We found a large number of candidate genes to be involved in the composition and formation of biocement in two species: Sabellaria alveolata and Phragmatopoma caudata. Our results indicate that the glue is likely to be composed by a large diversity of cement-related proteins, including Poly(S), GY-rich, H-repeat and miscellaneous categories. However, sequences divergence and differences in expression profiles between S. alveolata and P. caudata of cement-related proteins may reflect adaptation to the type of substratum used to build their tube, and/or to their habitat (temperate vs tropical, amplitude of pH, salinity ...). Related to the L-DOPA metabolic pathways and linked with the genes that were differentially expressed in the parathorax region, we found that tyrosinase and peroxidase gene families may have undergone independent expansion in the two Sabellariidae species investigated. Our data also reinforce the importance of protein modifications in cement formation. Altogether these new genomic resources help to identify novel transcripts encoding for cement-related proteins, but also important enzymes putatively involved in the chemistry of the adhesion process, such as kinases, and may correspond to new targets to develop biomimetic approaches. STATEMENTS OF SIGNIFICANCE: The diversity of bioadhesives elaborated by marine invertebrates is a tremendous source of inspiration to develop biomimetic approaches for biomedical and technical applications. Recent studies on the adhesion system of mussel, barnacle and sea star had highlighted the usefulness of high-throughput RNA sequencing in accelerating the development of biomimetic adhesives. Adhesion in sandcastle worms, which involves catechol and phosphate chemistries, polyelectrolyte complexes, supramolecular architectures, and a coacervation process, is a useful model to develop multipurpose wet adhesives. Using transcriptomic tools, we have explored the diversity of genes encoding for structural and catalytic proteins involved in cement formation of two sandcastle worm species, Sabellaria alveolata and Phragmatopoma caudata. The important genomic resource generated should help to design novel "blue" adhesives. PMID- 29597027 TI - Natural products with anti-aging potential: Affected targets and molecular mechanisms. AB - In recent years, there has been a great deal of attention toward the molecular machinery relevant to age-related progression controlled through the external intervention of polyphenols- an epigenetic-modulating diet. Natural products modulate cellular longevity through histone post-translational modification and can also induce the upregulation of autophagy, thus reducing the level of acetyl coenzyme A (AcCoA). In addition, the effect of caloric restriction (CR) on cancer related chronic inflammation is of great significance in aging. In line with this, SIRT1 protein levels are expanded in response to calorie restriction mimetics (CRM), in this way acting as autophagy inducers relevant to cancer prevention. PMID- 29597028 TI - Revisiting glycoside hydrolase family 20 beta-N-acetyl-d-hexosaminidases: Crystal structures, physiological substrates and specific inhibitors. AB - Glycoside hydrolase family 20 beta-N-acetyl-d-hexosaminidases (GH20s) catalyze the hydrolysis of glycosidic linkages in glycans, glycoproteins and glycolipids. The diverse substrates of GH20s account for their various roles in many important bioprocesses, such as glycoprotein modification, glycoconjugate metabolism, gamete recognition and chitin degradation in fungal cell walls and arthropod exoskeletons. Defects in human GH20s cause lysosomal storage diseases, Alzheimer's disease and osteoarthritis. Similarly, lower levels of GH20s arrest arthropod molting. Although GH20s are promising targets for drug and agrochemical development, designing bioactive molecules to target one specific enzyme is challenging because GH20s share a conserved catalytic mechanism. With the development of structural biology, the last two decades have witnessed a dramatic increase in crystallographic investigations of liganded and unliganded GH20s, providing core information for rational molecular designs. This critical review summarizes recent research advances in GH20s, with a focus on their structural basis of substrate specificity as well as on inhibitor design. As more crystal structures of targeted GH20s are determined and analyzed, dynamics of their catalysis and inhibition will also be elucidated, which will facilitate the development of new drugs, pesticides and agrochemicals. PMID- 29597029 TI - Dietary nutraceuticals as backbone for bone health. AB - Bone loss or osteoporosis, is a slow-progressing disease that results from dysregulation of pro-inflammatory cytokines. The FDA has approved number of drugs for bone loss prevention, nonetheless all are expensive and have multiple side effects. The nutraceuticals identified from dietary agents such as butein, cardamonin, coronarin D curcumin, diosgenin, embelin, gambogic acid, genistein, plumbagin, quercetin, reseveratrol, zerumbone and more, can modulate cell signaling pathways and reverse/slow down osteoporosis. Most of these nutraceuticals are inexpensive; show no side effect while still possessing anti inflammatory properties. This review provides various mechanisms of osteoporosis and how nutraceuticals can potentially prevent the bone loss. PMID- 29597030 TI - State of the art of aerobic granulation in continuous flow bioreactors. AB - In the wake of the success of aerobic granulation in sequential batch reactors (SBRs) for treating wastewater, attention is beginning to turn to continuous flow applications. This is a necessary step given the advantages of continuous flow treatment processes and the fact that the majority of full-scale wastewater treatment plants across the world are operated with aeration tanks and clarifiers in a continuous flow mode. As in SBRs, applying a selection pressure, based on differences in either settling velocity or the size of the biomass, is essential for successful granulation in continuous flow reactors (CFRs). CFRs employed for aerobic granulation come in multiple configurations, each with their own means of achieving such a selection pressure. Other factors, such as bioaugmentation and hydraulic shear force, also contribute to aerobic granulation to some extent. Besides the formation of aerobic granules, long-term stability of aerobic granules is also a critical issue to be addressed. Inorganic precipitation, special inocula, and various operational optimization strategies have been used to improve granule long-term structural integrity. Accumulated studies reviewed in this work demonstrate that aerobic granulation in CFRs is capable of removing a wide spectrum of contaminants and achieving properties generally comparable to those in SBRs. Despite the notable research progress made toward successful aerobic granulation in lab-scale CFRs, to the best of our knowledge, there are only three full-scale tests of the technique, two being seeded with anammox supported aerobic granules and the other with conventional aerobic granules; two other process alternatives are currently in development. Application of settling- or size-based selection pressures and feast/famine conditions are especially difficult to implement to these and similar mainstream systems. Future research efforts needs to be focused on the optimization of the granule-to-floc ratio, enhancement of granule activity, improvement of long-term granule stability, and a better understanding of aerobic granulation mechanisms in CFRs, especially in full-scale applications. PMID- 29597031 TI - Clinical, technological, and economic issues associated with developing new lung surfactant therapeutics. AB - Discovery of lung surfactant deficiency as a main cause of neonatal respiratory distress syndrome (NRDS) has influenced a steep increase in lung surfactant research. Although this has yielded impactful scientific discoveries, much of the basic research on lung surfactants has failed to translate into clinical practices. This is attributed to insufficient information covering the entire lung surfactant ecosystem, from the basic science to economics surrounding the development and clinical practices. In this manuscript, developments related to improving therapeutic lung surfactant as well as the degree of unmet need are analyzed from both technical and economic perspectives. Two potential opportunities are emphasized: (1) aerosolized lung surfactants to treat NRDS infants, and (2) synthetic lung surfactants for acute respiratory distress syndrome (ARDS) patients. Each has a modestly projected US market size of $120 million and $4 billion, well enough to make up for the high development costs associated with investigational drug development. Both opportunities have been pursued in the past, but to date these attempts have met with no success mainly due to technical limitations. With the recent advancements in both fields, technology improvements have created opportunities to solve both decades-old problems. PMID- 29597032 TI - Current advanced therapy cell-based medicinal products for type-1-diabetes treatment. AB - In the XXI century diabetes mellitus has become one of the main threats to human health with higher incidence in regions such as Europe and North America. Type 1 diabetes mellitus (T1DM) occurs as a consequence of the immune-mediated destruction of insulin producing beta-cells located in the endocrine part of the pancreas, the islets of Langerhans. The administration of exogenous insulin through daily injections is the most prominent treatment for T1DM but its administration is frequently associated to failure in glucose metabolism control, finally leading to hyperglycemia episodes. Other approaches have been developed in the past decades, such as whole pancreas and islet allotransplantation, but they are restricted to patients who exhibit frequent episodes of hypoglycemia or renal failure because the lack of donors and islet survival. Moreover, patients transplanted with either whole pancreas or islets require of immune suppression to avoid the rejection of the transplant. Currently, advanced therapy medicinal products (ATMP), such as implantable devices, have been developed in order to reduce immune rejection response while increasing cell survival. To overcome these issues, ATMPs must promote vascularization, guaranteeing the nutritional contribution, while providing O2 until vasculature can surround the device. Moreover, it should help in the immune-protection to avoid acute and chronic rejection. The transplanted cells or islets should be embedded within biomaterials with tunable properties like injectability, stiffness and porosity mimicking natural ECM structural characteristics. And finally, an infinitive cell source that solves the donor scarcity should be found such as insulin producing cells derived from mesenchymal stem cells (MSCs), embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). Several companies have registered their ATMPs and future studies envision new prototypes. In this review, we will discuss the mechanisms and etiology of diabetes, comparing the clinical trials in the last decades in order to define the main characteristics for future ATMPs. PMID- 29597033 TI - Nevirapine-polycaprolactone crystalline inclusion complex as a potential long acting injectable solid form. AB - Nevirapine (NVP) is recommended by WHO as the antiretroviral treatment to prevent HIV passing from mother to child. However, the once-daily oral administration results in poor patient compliance, and a long-acting injectable form of NVP is desirable. Using single-crystal X-ray diffraction and other characterization methods, we demonstrated NVP can form crystalline inclusion complex (IC) with the biodegradable hydrophobic poly(epsilon-caprolactone) (PCL), and investigated the potential of the NVP-PCL IC microparticles as a long-acting injectable solid form. Compared with pure NVP crystals and NVP/polylactide microparticles, the NVP PCL IC crystals showed significantly decreased solubility and slower dissolution rate, making it more suitable to be developed to achieve sustained-release profiles. In addition, the NVP-PCL IC microparticles with an average diameter below 10 MUm can be conveniently prepared by spray drying and are found to be easily injectable through a 25G needle. These results demonstrated the possibility of using drug-polymer IC microparticles as long-acting injectable forms, providing a new approach to design sustained-release drug products. PMID- 29597034 TI - Microsuspension of fatty acid esters of entecavir for parenteral sustained delivery. AB - Entecavir (EV), an anti-viral agent for hepatitis B infection, should be administered under fasted state, as intestinal absorption of this hydrophilic compound is markedly decreased under post-prandial conditions. Herein, in order to improve therapeutic adherence, a parenteral sustained delivery system was constructed, by synthesizing water-insoluble ester prodrugs of the nucleotide analogous with fatty acids. EV-3-palmitate (named EV-P), exhibited the lowest solubility in phosphate buffered saline (pH 7.4, 1.1 MUg/ml), with extended release profile compared with EV, EV-3-myristate, and EV-3-stearate, was selected as a candidate to formulate drug suspension. The crystalline suspension was fabricated using anti-solvent crystallization technique, with a mean particle size of 7.7 MUm. After subcutaneous (SC) injection in beagle dogs (0.43 mg/kg as EV), the plasma concentrations of EV were markedly protracted with lowered maximum plasma concentration (Cmax, 4.7 ng/ml), extended time required to reach Cmax (Tmax, 9.0 days), and lengthened elimination half-life (T1/2, 129.3 h) compared with those after oral administration (0.0154 mg/kg, Cmax, 15.4 ng/ml; Tmax, 0.01 days; T1/2, 4.1 h). The systemic exposure of the lipidic prodrug was below 0.1% compared with that of EV following SC injection, denoting that EV-P was rapidly converted into the parent compound in blood. Therefore, SC delivery of EV-P microsuspension can be an alternative to oral EV therapy, offering prolonged pharmacokinetic profile after single injection. PMID- 29597035 TI - Partitioning of dispersed nanoparticles in a realistic nasal passage for targeted drug delivery. AB - The complex nasal structure poses obstacles for efficient nasal drug administration beyond the nasal valve, especially when targeting the olfactory region. This study numerically detailed the naturally inhaled nanoparticle transport process from the initial releasing locations to the final deposited sites using a realistic human nasal passage. Dispersed nanoparticles at different coronal cross-sections were partitioned into multiple groups according to their final deposited locations. Results showed inhaled nanoparticles are more likely to move along the septum. Olfactory deposited particles entered the nose through the inner superior corner of the nostril; the middle meatus deposited particles entered the nose through the top third of the nostril; the inferior deposited particles entered via the bottom floor regions of the nostril. Therefore, targeted nasal inhalation therapies that intentionally release therapeutic particles from these recognized regions at the nostril plane can considerably improve the resultant topical disposition doses. However, it remains challenging to completely prevent undesired particle depositions as particles coming from the same location may produce multiple-sites depositions due to partition overlapping. Nevertheless, the fraction of undesired particle deposition is anticipated to be reduced at a great extent compared to unplanned releasing approaches.

PMID- 29597037 TI - A new magnetic nanodiamond/graphene oxide hybrid (Fe3O4@ND@GO) material for pre concentration and sensitive determination of sildenafil in alleged herbal aphrodisiacs by HPLC-DAD system. AB - A sensitive analytical methodology was investigated to concentrate and determine of sildenafil citrate (SLC) present at trace level in herbal supplementary products. The proposed method is based on simple and sensitive pre-concentration of SLC by using magnetic solid phase extraction with new developed magnetic nanodiamond/graphene oxide hybrid (Fe3O4@ND@GO) material as a sorbent. Experimental variables affecting the extraction efficiency of SLC like; pH, sample volume, eluent type and volume, extraction time and amount of adsorbent were studied and optimized in detail. Determination of sildenafil citrate after magnetic solid phase extraction (MSPE) was carried out by HPLC-DAD system. The morphology, composition, and properties of the synthesized hybrid material was characterized by Fourier transform infrared spectrometry (FT-IR), Raman spectrometry (Raman), X-ray diffraction spectrometry (XRD), scanning electron microscopy (SEM), mapping photographs, zeta potential analyzer, and BET surface area analysis. Under optimized conditions, linear range was ranged from 5.00 to 250.00 ng mL-1 with R2 of 0.9952. The limit of detection (LOD) was 1.49 ng mL-1 and the recoveries at two spiked levels were ranged from 94.0 to 104.1% with the relative standard deviation (RSD) < 7.1% (n = 5). The enhancement factor (EF) was 86.9. The results show that the combination MSPE with HPLC-DAD is a suitable and sensitive method for the determination of SLC in real samples. PMID- 29597038 TI - Simultaneous determination of eight bioactive compounds by LC-MS/MS and its application to the pharmacokinetics, liver first-pass effect, liver and brain distribution of orally administrated Gouteng-Baitouweng (GB) in rats. AB - Only focusing on the circulating levels is insufficient for the comprehensive understanding of the physiological disposition of herbal medicine in vivo. Therefore, we conducted the comprehensive investigation on the in vivo dynamic process of orally administrated Gouteng-Baitouweng (GB), a classical herb pair with anti-Parkinson potentials. Serving as the technical base, a sensitive and selective liquid chromatography-tandem mass spectrometry method was established and validated in the plasma, liver and brain, for simultaneous determination of five alkaloids (rhynchophylline, isorhynchophylline, corynoxeine, isocorynoxeine and geissoschizine methyl ether) and three saponins (anemoside B4, anemoside A3 and 23-hydroxybetulinic acid). Following liquid-liquid extraction, favorable chromatographic behaviors of eight analytes were obtained on Waters Xbrigde C18 column within 13 min. This method elicited good linearity for the analytes at the concentration range of 0.3-1000 or 1.8-6000 ng/mL with favorable precision, accuracy and stability. Following oral administration of GB (25 g/kg) in rats, this method was applied to the quantitative analysis in the portal vein plasma, liver, systemic plasma, and brain. Consequently, anemoside B4 was of the highest exposure, followed by 23-hydroxybetulinic acid, anemoside A3, rhynchophylline and isocorynoxeine in vivo. Notably, three saponins were all observed with certain exposure in the brain, along with rhynchophylline at low levels. Besides, five alkaloids and 23-hydroxybetulinic acid underwent serious liver first-pass effect. Hence, the pharmacokinetics, liver first-pass effect, liver and brain distribution of ingredients in GB were clarified, which laid a solid foundation for interpreting its efficacy and safety. PMID- 29597039 TI - 3D-Image analysis of the impact of toothpaste abrasivity on the progression of simulated non-carious cervical lesions. AB - OBJECTIVES: To investigate the effect of toothpaste abrasive level on the progression of non-carious cervical lesions (NCCLs) using 3D-image subtraction. METHODS: Upper first premolars were allocated into seven groups (n = 16) of toothpaste/abrasive slurries: A-Zeodent113/5%, B-Zeodent124/10%, C Zeodent103/15%, D-Sensodyne Pronamel, E-Crest Cavity-Protection, F-Crest Pro Health-Whitening, and G-Deionized water (DIW). Teeth were mounted on acrylic blocks, and their root surfaces covered with acrylic resin, except for 2-mm near the cemento-enamel junction that was exposed to toothbrushing. Specimens were brushed with the slurries for 5000-, 15,000-, 35,000- and 65,000-strokes. Impressions were taken at baseline and after each brushing time, and then scanned by a 3D optical profilometer. Dentine volume loss was calculated by image subtraction software and subjected to mixed-model ANOVA and multiple comparison tests (alpha = 0.05). RESULTS: No significant differences among slurries were observed at 5000 and 15,000. At 35,000, F showed higher loss than all other groups except C, which did not differ from the others. At 65,000, F (4.19 +/- 3.29 mm3) showed the highest loss, followed by C (2.33 +/- 1.47 mm3), which differed from all the other groups except B (1.85 +/- 0.91 mm3). Groups B, A (1.35 +/- 0.65 mm3), D (1.17 +/- 0.48 mm3), E (1.40 +/- 0.68 mm3) and G (1.12 +/- 0.73 mm3) did not differ from each other. Groups F and C showed significant increase of volume loss starting at 35,000, while B, A, D and E only at 65,000; no increase loss was observed for G. CONCLUSIONS: 3D-image subtraction was able to quantify and differentiate tooth loss, but only at advanced stages. The progression of NCCLs was more evident and faster for highly abrasive slurries. CLINICAL SIGNIFICANCE: Upon root dentin exposure, brushing with lower abrasive dentifrices is advisable to reduce the risk for NCCLs development.

AB - OBJECTIVE: To evaluate the effect of shading technique and thickness on the color stability and translucency of translucent zirconia after coffee thermocycling. METHODS: Specimens in different thicknesses (1; 1.5; 2 mm) (n = 4 for each thickness) were sectioned from translucent preshaded zirconia (Pre) and externally shaded zirconia (Ext). After sintering, specimens were glazed and subjected to 10,000 thermocycling in coffee solution. The color coordinates of specimens were measured with a spectroradiometer before and after coffee thermocyling. Color differences and relative translucency parameter (RTP) values were calculated with CIEDE2000 color difference and TPCIEDE2000 formulas. ANOVA was used to analyze the CIEDE2000 color difference and RTP values (alpha = 0.05). RESULTS: According to 2-way ANOVA, no significant effect of shading technique and thickness on the color difference values was found (P > .05). According to 3-way ANOVA, a significant interaction between the shading technique and thickness (P < .0001) was found for RTP. The RTP parameter decreased with the increase in the thickness. Ext specimens presented significantly higher RTP than Pre specimens (P < .0001), except for between Ext 1 mm and Pre 1 mm (P = .179). CONCLUSIONS: Neither shading technique nor tested thicknesses affected the color of translucent zirconia. Shading technique and thickness affected the RTP of translucent zirconia. The RTP was inversely affected with the thickness of the material. Externally shaded zirconia presented higher RTP than preshaded zirconia for specimens thicker than 1 mm. CLINICAL SIGNIFICANCE: Discoloration with coffee was insignificant for the tested translucent zirconia in tested thicknesses (1, 1.5, 2 mm). When a translucent restoration is intended, thinner externally shaded translucent zirconia restorations should be preferred instead of preshaded translucent zirconia. PMID- 29597041 TI - Development of core-shell nanocarrier system for augmenting piperine cytotoxic activity against human brain cancer cell line. AB - Brain tumor has a low prognosis with only 15% survival rate (5 years after diagnosis). Many of the current therapeutics have limited activity due to their inability to cross the blood brain barrier which retards drug accumulation in tumor site and causes drug resistance. Piperine, a phytochemical drug with poor solubility, could be an alternative to current therapeutics after evading its solubility and permeability limitations. Piperine micellization was optimized to improve drug solubility. Positively charged trimethyl-chitosan was synthesized then electrostatically adsorbed onto piperine nanomicelles forming core-shell nanoparticles. Physicochemical and morphological characterizations, and in-vitro release were performed. Cytotoxicity on human brain cancer cell line (Hs683) was evaluated using IC50 determination, cell cycle arrest analysis, apoptosis and enzyme-linked immunosorbent assay. Optimum piperine-loaded core-shell nanoparticles were successfully fabricated with double-phase release model. Significant improvement in cytotoxicity than free drug was noted with increasing in G2/M-phase and pre-GI-phase population, apoptotic/necrotic rates and inhibition of CDK2a. PMID- 29597042 TI - Nasal dilation effects on olfactory deposition in unilateral and bi-directional deliveries: In vitro tests and numerical modeling. AB - The human nose can expand either actively or passively to increase airflow. Nasal dilation may alter drug delivery efficiencies in the nasal airway or olfactory region. However, the dosage enhancement from nasal dilations has not been quantified. The mechanisms underlying the dilation-induced deposition variation are also not clear. This study aims to quantify the nasal dilation effects on drug delivery in the nasal airway and olfactory region using in vitro tests and numerical analysis. Two variants of an existing normal nasal airway model were developed with different levels of airway dilation. Airway dimensions were quantified in terms of hydraulic diameter, cross-sectional area, and surface area to volume ratio. Sectional nose casts were prepared using a 3-D printer for visualizing deposition patterns and quantifying delivered dosages. A well validated computational fluid-particle dynamics (CFPD) model was utilized to understand the underlying mechanisms in the unilateral and bi-directional deliveries. In vitro tests show that nasal dilation lowered the total dosage in the nose but increased the dosage to the olfactory region in both the unilateral and bi-directional deliveries. Compared to the normal nose with unilateral delivery, nasal dilation enhanced the olfactory deposition by a factor of 2.2, while nasal dilatation with the bi-directional delivery increased by a factor of 4. Complementary numerical analyses revealed the growth of a recirculation zone in the middle meatus of dilated noses, which induced lower pressure and increased ventilation to the upper nose. In bi-directional deliveries, a significantly higher fraction of airflow was ventilated to the upper airway in the outflow side of the nose and contributed to the elevated olfactory dosage. Nasal dilation in combination with the bi-directional delivery is recommended over the conventional unilateral method for olfactory targeting. PMID- 29597043 TI - Pegylated poly(anhydride) nanoparticles for oral delivery of docetaxel. AB - The aim of this work was to investigate the potential of pegylated poly(anhydride) nanoparticles to enhance the oral bioavailability of docetaxel (DTX). Nanoparticles were prepared after the incubation between the copolymer of methyl vinyl ether and maleic anhydride (Gantrez(r) AN), poly(ethylene glycol) (PEG2000 or PEG6000) and docetaxel (DTX). The oral administration of a single dose of pegylated nanoparticles to mice provided sustained and prolonged therapeutic plasma levels of docetaxel for up 48-72 h. In addition, the relative oral bioavailability of docetaxel was around 32%. The organ distribution studies revealed that docetaxel underwent a similar distribution when orally administered encapsulated in nanoparticles as when intravenously as Taxotere(r). This observation, with the fact that the clearance of docetaxel when loaded into the oral pegylated nanoparticles was found to be similar to that of intravenous formulation, suggests that docetaxel would be released at the epithelium surface and then absorbed to the circulation. PMID- 29597044 TI - Ex-vivo absorption study of lysine R-lipoate salt, a new pharmaceutical form of R ALA. AB - Alpha-lipoic acid (ALA) oral supplements were used in many pathologies associated with increased oxidative stress. Although only R-ALA is considered the biologically active form, R,S-ALA is used in therapeutic applications even showing poor water solubility. The aim of this work was to study the absorption and transport mechanism across the intestinal barrier of new R-ALA stable and water soluble form, consisting in the lysine R-ALA salt, in presence and absence of specific inhibitors of Na+/multivitamin (SMVT) and monocarboxylic acids (MCT). The absorption of a new ALA form was investigated at rat everted sacs in comparison with R-ALA, S-ALA, and R,S-ALA. Results showed that duodenum is the best portion of intestine for ALA forms absorption. The absorption percentage of R-ALA, S-ALA, R,S-ALA, and lysine R-ALA salt was 66%, 43%, 55%, and 70%, respectively. The modest effect of the SMVT inhibitor biotin demonstrated that this transporter system is not principally involved in the absorption of lysine R lipoate salt across the rat intestinal barrier. On the contrary, the MCT inhibitor octanoic acid significantly reduced the transport of this salt, whit an absorption decrease of R-ALA and lysine R-lipoate salt of 28% and 24%, respectively. Since the highest concentration of these inhibitors did not completely inhibit the absorption of lysine R-lipoate salt, other transport mechanisms probably operate for its intracellular delivery. The new form of ALA, lysine R-lipoate salt, was the most absorbed respect to the other ALA forms demonstrating that this compound is more suitable for oral administration. This new salt could represent a promising candidate for ALA oral supplementation. PMID- 29597045 TI - In situ nonlinear ultrasonic technique for monitoring microcracking in concrete subjected to creep and cyclic loading. AB - This research conducts in situ nonlinear ultrasonic (NLU) measurements for real time monitoring of load-induced damage in concrete. For the in situ measurements on a cylindrical specimen under sustained load, a previously developed second harmonic generation (SHG) technique with non-contact detection is adapted to a cylindrical specimen geometry. This new setup is validated by demonstrating that the measured nonlinear Rayleigh wave signals are equivalent to those in a flat half space, and thus the acoustic nonlinearity parameter, beta can be defined and interpreted in the same way. Both the acoustic nonlinearity parameter and strain are measured to quantitatively assess the early-age damage in a set of concrete specimens subjected to either 25 days of creep, or 11 cycles of cyclic loading at room temperature. The experimental results show that the acoustic nonlinearity parameter is sensitive to early-stage microcrack formation under both loading conditions - the measured beta can be directly linked to the accumulated microscale damage. This paper demonstrates the potential of NLU for the in situ monitoring of mechanical load-induced microscale damage in concrete components. PMID- 29597046 TI - Omnidirectional shear horizontal wave based tomography for damage detection in a metallic plate with the compensation for the transfer functions of transducer. AB - Guided-wave based damage detection for plates has been widely studied for structural health monitoring. Because most of the earlier studies used dispersive Lamb waves, substantial efforts had to be made to alleviate the dispersive and multi-modal nature of Lamb waves and the effect of surface conditions. In contrast, shear-horizontal (SH) waves have better propagation characteristics suitable for the detection of damages in plates, but SH waves have not been widely used due to the lack of efficient methods to generate and sense omnidirectional SH waves. The objective of this study is to construct diagnostic images of damaged plates by using omnidirectional SH waves with a special emphasis on the compensation of the frequency-dependence of the SH wave transducers. The compensation is necessary to have reliable diagnostic images because its frequency-dependent characteristics considerably can affect imaging quality if they are not considered. Consequently, simplified, yet effective, models representing the transfer functions of the omnidirectional SH wave magnetostrictive patch transducer (OSH-MPT) are developed in this paper. To visualize the position and shape of the structural damages in a metallic plate, the virtual time-reversal imaging method is used and two alternative techniques are considered to compensate for the effects of the transfer functions of transducers in the imaging processes. The imaging results after the compensation appear quite promising, suggesting that the omnidirectional SH wave based enhanced time-reversal imaging can be an efficient inspection method for plate structures. PMID- 29597047 TI - Nanomagnetic Modulation of Tumor Redox State. AB - Modulation of reactive oxygen and nitrogen species in a tumor could be exploited for nanotherapeutic benefits. We investigate the antitumor effect in Walker-256 carcinosarcoma of magnetic nanodots composed of doxorubicin-loaded Fe3O4 nanoparticles combined with electromagnetic fields. Treatment using the magnetic nanodot with the largest hysteresis loop area (3402 erg/g) had the greatest antitumor effect with the minimum growth factor 0.49 +/- 0.02 day-1 (compared to 0.58 +/- 0.02 day-1 for conventional doxorubicin). Electron spin resonance spectra of Walker-256 carcinosarcoma treated with the nanodots, indicate an increase of 2.7 times of free iron (that promotes the formation of highly reactive oxygen species), using the nanodot with the largest hysteresis loop area, compared to conventional doxorubicin treatment as well as increases in ubisemiquinone, lactoferrin, NO-FeS-proteins. Hence, we provide evidence that the designed magnetic nanodots can modulate the tumor redox state. We discuss the implications of these results for cancer nanotherapy. PMID- 29597048 TI - Screening for canine transitional cell carcinoma (TCC) by SERS-based quantitative urine cytology. AB - Canine lower urinary tract neoplasia is a clinically important disease process that has high mortality due to late stage diagnosis and poorly durable response to treatment. Non-invasive diagnostic techniques (e.g. dipstick test, urine cytology) currently have poor diagnostic value, while more invasive tests (e.g. cystoscopy and biopsy) are costly and often require general anesthesia. We have developed and herein describe a quantitative cytological analysis method based on the use of surface-enhanced Raman spectroscopy (SERS), for identifying cancerous transitional cells in urine using SERS biotags (SBTs) carrying the peptide PLZ4 (amino acid sequence cQDGRMGFc) that targets malignant transitional cells. By analyzing the ratio of the PLZ4-SBTs to an on board control we were able to show that transitional cells had significantly higher ratios (P < 0.05) in patients diagnosed with transitional cell carcinoma (TCC) than in healthy samples. PMID- 29597049 TI - Early Recognition of Heart Failure: A Call for Action. PMID- 29597050 TI - Did Frederic Chopin Die From Heart Failure? AB - On October 17, 1849, Poland's greatest composer, Frederic Chopin (1810-1849) died aged 39. His cause of death remains unknown. An investigation of the documental sources was performed to reconstruct the medical history of the artist. Since his earliest years, his life had been dominated by poor health. Recurrent episodes of cough, fever, headaches, lymphadenopathy- a series of symptoms that may be attributed to viral respiratory infections- manifested in his teens. Later in life, he had chest pain, hemoptysis, hematemesis, neuralgia, and arthralgia. Exhaustion and breathlessness characterized all his adult life. Coughing, choking, and edema of the legs and ankles manifested four months before his death. Several hypotheses ranging from cystic fibrosis to alpha-1 anti-trypsin deficiency and pulmonary tuberculosis have been proposed to explain Chopin's lifelong illness. We suggest that Chopin had dilated cardiomyopathy with consequent heart failure and cirrhosis that caused his death. PMID- 29597051 TI - Prognostic Impact of Pulmonary Artery Pulsatility Index (PAPi) in Patients With Advanced Heart Failure: Insights From the ESCAPE Trial. AB - BACKGROUND: The pulmonary artery pulsatility index (PAPi), defined as the ratio of pulmonary artery pulse pressure to right atrial pressure, emerged as a powerful predictor of right ventricular (RV) failure in patients with acute inferior myocardial infarction and those undergoing left ventricular assist device placement; however, its prognostic utility in the advanced heart failure population remains largely unknown. METHODS AND RESULTS: We comparatively analyzed PAPi with traditional indices of RV function including RV stroke work index and right atrial/pulmonary capillary wedge pressure ratio (RAP/PCWP) in the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness trial. Median PAPi score was 2.35 in 190 patients. PAPi was significantly associated with clinical (jugular venous distention, ascites, edema), echocardiographic (right atrial size, vena cava size, tricuspid regurgitation velocity), and hemodynamic signs of RV failure (RAP, PCWP); all P < .05. In addition, PAPi was associated with the measures of left ventricular function, including ejection fraction, cardiac index, and PCWP (all P < .05). In Cox regression analysis, PAPi was an independent predictor of primary endpoint of death or hospitalization at 6 months (hazard ratio 0.91 [95% confidence interval 0.84-0.99], P = .022), whereas RA pressure, RV stroke work index, or RA/PCWP were not. CONCLUSIONS: PAPi serves as a marker of RV dysfunction and strongly predicts adverse clinical events in patients with advanced heart failure. Incorporating PAPi into existing risk models can substantially improve patient selection for advanced therapies and clinical outcomes in this population. PMID- 29597052 TI - Risk of Ischemic Stroke in Patients Newly Diagnosed With Heart Failure: Focus on Patients Without Atrial Fibrillation. AB - BACKGROUND: Heart failure (HF) is associated with an incremental risk of stroke, but limited real-world data exist in patients with HF without atrial fibrillation (AF). OBJECTIVES: To quantify the incremental risk of ischemic stroke among newly diagnosed patients with HF and without AF. METHODS: Adults with HF and >=18 months of enrollment before their index HF (ie, baseline period) were identified in Truven Health Analytics MarketScan Databases (January 2010-April 2015). Patients without AF during baseline and without an ischemic stroke within 14days of the index date were propensity score matched 1:1 to individuals with neither HF nor AF and observed for ischemic stroke. A similar analysis was performed for the overall HF population. Incidence rates were compared using incidence rate ratios between HF and non-HF cohorts; Kaplan-Meier analyses with log-rank tests were used to compare incidence rates over time. RESULTS: A total of 66,414 patients with HF were identified, of which 52,005 did not have AF. Patients with HF without AF had significantly higher rates of ischemic stroke than patients without HF without AF during follow-up (incidence rate ratio 1.91 [95% confidence interval 1.75-2.09], P < .001). Ischemic stroke rates remained significantly higher for patients with HF over time among individuals without AF (P < .001 for log-rank test at 12, 24, and 36 months). Similar results were found for the overall HF population. CONCLUSIONS: Even in the absence of AF, patients with HF are at heightened risk of ischemic stroke compared with patients without HF. PMID- 29597053 TI - Associations With and Prognostic and Discriminatory Role of N-Terminal Pro-B-Type Natriuretic Peptide in Heart Failure With Preserved Versus Mid-range Versus Reduced Ejection Fraction. AB - BACKGROUND: The aim of this study was to characterize N-terminal pro-B-type natriuretic peptide (NT-proBNP) in terms of determinants of levels and of its prognostic and discriminatory role in heart failure with mid-range (HFmrEF) versus preserved (HFpEF) and reduced (HFrEF) ejection fraction. METHODS AND RESULTS: In 9847 outpatients with HFpEF (n = 1811; 18%), HFmrEF (n = 2122; 22%) and HFrEF (n = 5914; 60%) enrolled in the Swedish Heart Failure Registry, median NT-proBNP levels were 1428, 1540, and 2288 pg/mL, respectively. Many determinants of NT-proBNP differed by ejection fraction, with atrial fibrillation (AF) more important in HFmrEF and HFpEF, diabetes and hypertension in HFmrEF, and age and body mass index in HFrEF and HFmrEF, whereas renal function, New York Heart Association functional class, heart rate, and anemia were similar. Hazard ratios for death and death/HF hospitalization for NT-proBNP above the median ranged from 1.48 to 2.00 and were greatest for HFmrEF and HFpEF. Areas under the receiver operating characteristic curve for death and death/HF hospitalization were greater in HFmrEF than in HFpEF and HFrEF and were reduced by AF in HFpEF and HFmrEF but not in HFrEF. CONCLUSIONS: In HFpEF and especially HFmrEF, NT-proBNP was more prognostic and discriminatory, but also more affected by confounders such as AF. These data support the use of NT-proBNP for eligibility, enrichment, and surrogate end points in HFpEF and HFmrEF trials, and suggest that cutoff levels for eligibility should be carefully tailored to comorbidity.

PMID- 29597055 TI - Hepatitis E virus in feral rabbits along a rural-urban transect in Central Germany. AB - Rabbit associated genotype 3 hepatitis E virus (HEV) strains were detected in feral, pet and farm rabbits in different parts of the world since 2009 and recently also in human patients. Here, we report a serological and molecular survey on 72 feral rabbits, collected along a rural-urban transect in and next to Frankfurt am Main, Central Germany. ELISA investigations revealed in 25 of 72 (34.7%) animals HEV-specific antibodies. HEV derived RNA was detected in 18 of 72 (25%) animals by reverse transcription-polymerase chain reaction assay. The complete genomes from two rabbitHEV-strains, one from a rural site and the other from an inner-city area, were generated by a combination of high-throughput sequencing, a primer walking approach and 5'- and 3'- rapid amplification of cDNA ends. Phylogenetic analysis of open reading frame (ORF)1-derived partial and complete ORF1/ORF2 concatenated coding sequences indicated their similarity to rabbit-associated HEV strains. The partial sequences revealed one cluster of closely-related rabbitHEV sequences from the urban trapping sites that is well separated from several clusters representing rabbitHEV sequences from rural trapping sites. The complete genome sequences of the two novel strains indicated similarities of 75.6-86.4% to the other 17 rabbitHEV sequences; the amino acid sequence identity of the concatenated ORF1/ORF2-encoded proteins reached 89.0 93.1%. The detection of rabbitHEV in an inner-city area with a high human population density suggests a high risk of potential human infection with the zoonotic rabbitHEV, either by direct or indirect contact with infected animals. Therefore, future investigations on the occurrence and frequency of human infections with rabbitHEV are warranted in populations with different contact to rabbits. PMID- 29597056 TI - Emergence of multiple norovirus strains in Thailand, 2015-2017. AB - Norovirus is a major cause of non-bacterial acute gastroenteritis worldwide. Infection can be sporadic or result in widespread outbreaks. The surveillance of norovirus samples (n = 1591) obtained from patients with diarrhea in Thailand from January 2015 to February 2017 suggested that the predominance of norovirus GII.4 often seen in sporadic infection had been superseded by the emergence of GII.17. More recently, a sharp increase in acute gastroenteritis associated with norovirus GII.P16-GII.2 recombinant strain was observed at the end of 2016. Thus, previously rare norovirus strains and their recombinant derivatives may be more frequently responsible for future outbreaks. PMID- 29597057 TI - Relationship between incivility experiences and nursing professional values among nursing students: Moderating effects of coping strategies. AB - BACKGROUND: During clinical practice, nursing students develop their professional role and internalize the values of the nursing profession. Unfortunately, it also often exposes them uncivil behaviors from nurses. OBJECTIVES: To identify the relationship between incivility experiences and nursing professional values, and investigate the potential moderating effects of coping strategies in this relationship. DESIGN AND METHODS: This was a descriptive, cross-sectional study. Data were collected from 203 nursing students using questionnaires. The questionnaire comprised sections assessing participant characteristics, incivility experiences, coping strategies, and nursing professional values. Multiple regression analysis was used to identify the relationship between incivility experiences and nursing professional values, as well as the interaction effect of incivility experiences and coping strategies on nursing professional values. RESULTS: Incivility experiences were negatively related to nursing professional values. Furthermore, seeking support moderated the relationship between incivility experiences and nursing professional values. In other words, as incivility experiences increased, nursing students who used more seeking social support tended to have stronger nursing professional values than did those who used this coping strategy less. CONCLUSION: To improve the nursing professional values of nursing students, educators must inform nursing managers when nurses direct uncivil behaviors towards students. Educators should also listen to students' experiences, support them emotionally, and encourage students to engage in seeking social support. PMID- 29597058 TI - Structure of 3,6-dideoxy-3-[(R)-2-hydroxypropanoylamino]-D-galactose-containing O polysaccharide from marine bacterium Simiduia litorea KMM 9504T. AB - The O-polysaccharide was isolated from the lipopolysaccharide of a marine bacterium Simiduia litorea KMM 9504T and studied by chemical methods along with 1D and 2D 1H and 13C NMR spectroscopy including 1H,1H-TOCSY, 1H,1H-COSY, 1H,1H ROESY, 1H,13C-HSQC and 1H,13C-HMBC experiments. The following new structure of the O-polysaccharide of S. litorea KMM 9504T containing D-galacturonamide, 2 acetamido-2,6-dideoxy-D-glucose and 3,6-dideoxy-3-[(R)-2-hydroxypropanoylamino]-D galactose was established. PMID- 29597059 TI - Chemical application strategies to protect water quality. AB - Management of turfgrass on golf courses and athletic fields often involves application of plant protection products to maintain or enhance turfgrass health and performance. However, the transport of fertilizer and pesticides with runoff to adjacent surface waters can enhance algal blooms, promote eutrophication and may have negative impacts on sensitive aquatic organisms and ecosystems. Thus, we evaluated the effectiveness of chemical application setbacks to reduce the off site transport of chemicals with storm runoff. Experiments with water soluble tracer compounds confirmed an increase in application setback distance resulted in a significant increase in the volume of runoff measured before first off-site chemical detection, as well as a significant reduction in the total percentage of applied chemical transported with the storm runoff. For example, implementation of a 6.1 m application setback reduced the total percentage of an applied water soluble tracer by 43%, from 18.5% of applied to 10.5% of applied. Evaluation of chemographs revealed the efficacy of application setbacks could be observed with storms resulting in lesser (e.g. 100 L) and greater (e.g. > 300 L) quantities of runoff. Application setbacks offer turfgrass managers a mitigation approach that requires no additional resources or time inputs and may serve as an alternative practice when buffers are less appropriate for land management objectives or site conditions. Characterizing potential contamination of surface waters and developing strategies to safeguard water quality will help protect the environment and improve water resource security. This information is useful to grounds superintendents for designing chemical application strategies to maximize environmental stewardship. The data will also be useful to scientists and regulators working with chemical transport and risk models. PMID- 29597060 TI - Residue and distribution of triforine in different cultivars and fruit periods of watermelon under field conditions. AB - The dissipation of triforine in the immature and mature fruit periods was investigated under field conditions. Residue levels of triforine in watermelon were determined by gas chromatography with an electron capture detector (GC-ECD). The decline curves of triforine residues in the watermelon corresponded with first-order kinetics. The half-lives of triforine in Dark Belle and Shiny Boy were 2.10-2.57 days and 2.31-2.67 days respectively. Meanwhile, the half-lives of triforine in the immature and mature fruit periods were 1.69-2.04 days and 2.89 3.85 days, respectively. In the terminal residue experiment, the terminal residues of triforine in the watermelon flesh and peel were below 0.01 mg/kg to 0.05 mg/kg and 0.03 mg/kg to 0.36 mg/kg, respectively. The dissipation rates of triforine varied in different cultivars of watermelon, and even in the same cultivar, the half-lives of triforine significantly varied in the different fruit periods. Although triforine is a fungicide within the suction, the terminal residues in the peel and flesh were very significant. PMID- 29597061 TI - Individuality of masticatory performance and of masticatory muscle temporal parameters. AB - OBJECTIVE: Mammalian mastication serves to improve intra-oral food reduction. Insufficient food reduction creates potential swallowing problems, whereas over reduction may accelerate tooth wear and increase feeding time. Either extreme has consequences. The study's objectives were: (1) to study the relationship between food reduction, number of chews in a sequence, and chewing rate, (2) to study how controlling the number of chews and chewing rate variability affects food reduction, and (3) to assess how dentoskeletal morphological and electromyographical (EMG) characteristics impact food reduction. DESIGN: Twenty three healthy, fully-dentate adults chewed a standardized test food under three conditions: (1) no control, (2) number of chews controlled, and (3) number of chews and chewing rate controlled. EMG activity was sampled from masseter and temporalis muscles bilaterally. Demographic, occlusal contact area in maximum intercuspation, and cephalometric data were obtained. RESULTS: In uncontrolled conditions, food reduction and bout duration varied more than expected across subjects. Subjects with poor reduction under controlled conditions were those with poor reduction under uncontrolled conditions. Only occlusal contact area correlated with chewing performance under uncontrolled conditions. Chewing cycle duration, EMG burst duration, and EMG peak onset latency increased when the number of chews was restricted. EMG amplitude, a surrogate for bite force, increased in tasks controlling the number of chews and chewing rate. Chewing rate variability was difficult to diminish below individual-specific levels. CONCLUSIONS: Results: provided evidence that bite force, chewing rate, chewing performance and chewing bout duration reflected individual preferences. Future work will determine whether similar findings occur among other mammals. PMID- 29597062 TI - Expression and localization of phosphodiesterase 2A in the submandibular gland of mice. AB - OBJECTIVES: Phosphodiesterases comprise a superfamily of enzymes that hydrolyze and inactivate cyclic AMP (cAMP) and/or cyclic GMP (cGMP), thereby regulating cellular signaling mechanisms. We herein investigated the production of phosphodiesterase 2A (PDE2A) in the mouse submandibular gland. DESIGN: The expression and localization of the mRNA and protein of PDE2A were examined in the submandibular gland of male and female mice using the reverse transcription polymerase chain reaction, in situ hybridization, Western blotting, and immunohistochemistry. RESULTS: Among the different species of phosphodiesterases examined in the mouse submandibular gland, PDE2A, which hydrolyzes cAMP and cGMP, exhibited a marked sexual difference; it was more abundantly expressed in females. The mRNA and protein signals for PDE2A were intense in all acinar and duct portions, including the striated duct, in females, whereas in males, these signals were markedly weaker in the granular convoluted duct, the counterpart of the female striated duct, than in acini and other duct portions. Furthermore, the signals for protein kinases A and G1, which are intracellular effectors of cAMP and cGMP, respectively, were markedly weaker in the male granular convoluted duct. CONCLUSIONS: These results suggest that cyclic nucleotide-dependent signaling mechanisms function poorly in granular convoluted duct cells in the mouse submandibular gland. PMID- 29597063 TI - Implementing a Novel Guideline to Prevent Hospital-Acquired Pressure Ulcers in a Trauma Population: A Patient-Safety Approach. AB - BACKGROUND: The development of hospital-acquired pressure ulcers (HAPUs) is a common complication associated with immobilization and prolonged hospitalization in trauma patients. Our semi-annual Trauma Quality Improvement Program report identified HAPUs as an outlier complication. We used a hospital-wide initiative to reduce the incidence of HAPUs among our trauma patient population. Our study aimed to determine whether the implemented measures would decrease HAPUs incidence rates. STUDY DESIGN: We reviewed adult trauma patients during a 3-year period. The novel care-based platform and preventive measures for reducing HAPUs included the following components: pressure-reducing beds; improved and protocolized nutritional support; mandatory 2-hour change of posture; turning clocks; early surgical intervention; spot checks by our wound care nurse; and education to patients and caregivers. Paired-sample t-test and chi-square analyses were used, with significance defined as p < 0.05. RESULTS: A total of 9,755 patients were admitted to our trauma services in the study period. Of these, HAPUs developed in 89 patients (mean age 57.9 years and 48 [54%] were female). The Injury Severity Score ranged from 1 to 75, with a mean of 20 in patients with HAPUs compared with 8 in patients without HAPUs during the same study period. The incidence of HAPUs at our institution was initially 1.36%, which decreased to 0.98% in year 2 and to 0.39% in year 3 (p = 0.002). CONCLUSIONS: The novel 7-step care-based process changes, acquisition of specialized equipment, and educational initiatives implemented were associated with a significant decrease in the incidence rates of HAPUs. PMID- 29597064 TI - Centromeric retrotransposons and centromere function. AB - The centromeric DNA of most multicellular eukaryotes consists of tandem repeats (TR) that bind centromere-specific proteins and act as a substrate for the efficient repair of frequent double-stranded DNA breaks. Some retrotransposons target active centromeres during integration with such specificity that they can be used to deduce current and historic centromere positions. The roles of transposons in centromere function remain incompletely understood but appear to include maintaining centromere size and increasing the repeat content of neocentromeres that lack TR. Retrotransposons are known to give rise to TR. Centromere-targeting elements thus have the potential to replace centromeric TR essentially in situ, providing a mechanism to explain the centromere paradox, that is, the presence of unrelated centromeric TRs in closely related species. PMID- 29597065 TI - Modeling cognitive deficits following neurodegenerative diseases and traumatic brain injuries with deep convolutional neural networks. AB - The accurate diagnosis and assessment of neurodegenerative disease and traumatic brain injuries (TBI) remain open challenges. Both cause cognitive and functional deficits due to focal axonal swellings (FAS), but it is difficult to deliver a prognosis due to our limited ability to assess damaged neurons at a cellular level in vivo. We simulate the effects of neurodegenerative disease and TBI using convolutional neural networks (CNNs) as our model of cognition. We utilize biophysically relevant statistical data on FAS to damage the connections in CNNs in a functionally relevant way. We incorporate energy constraints on the brain by pruning the CNNs to be less over-engineered. Qualitatively, we demonstrate that damage leads to human-like mistakes. Our experiments also provide quantitative assessments of how accuracy is affected by various types and levels of damage. The deficit resulting from a fixed amount of damage greatly depends on which connections are randomly injured, providing intuition for why it is difficult to predict impairments. There is a large degree of subjectivity when it comes to interpreting cognitive deficits from complex systems such as the human brain. However, we provide important insight and a quantitative framework for disorders in which FAS are implicated. PMID- 29597066 TI - The compensation effects of physiology and yield in cotton after drought stress. AB - The objective of this study was to investigate the root growth compensatory effects and cotton yield under drought stress. The results indicate that the root dry weight, boll weight, and cotton yield increased in both the drought-resistant cultivar (CCRI-45) and the drought-sensitive cultivar (CCRI-60). Compensation effects were exhibited under the three-day drought stress treatment at a soil relative water content (SRWC) of 60% and 45% during the seedling stage, and flowering and boll-forming stage over two years. The yield of the drought resistant cultivar (CCRI-45) was higher than the control, however, following the six-day 45% SRWC drought treatments, the yield of the drought-sensitive cultivar (CCRI-60) was lower than the control. The soluble sugar content, proline content, superoxide dismutase (SOD) activity, and peroxidase (POD) activity of the roots increased under drought stress and then decreased after re-watering, although the values remained higher than those of the controls for a short period. These physiological measures may represent stress reactions and thus may not indicate factors that result in compensation effects. However, catalase (CAT) activity and gibberellic acid (GA) content of the roots decreased under drought stress. After re-watering, the CAT activity and the GA content increased and were significantly higher than those of the controls under the six-day 60% SRWC and 45% SRWC drought treatments. The abscisic acid (ABA) content of the roots increased under drought stress. After re-watering, the ABA content decreased to a lower level under the three and six-day 60% SRWC and 45% SRWC drought treatments than in the controls. According to an analysis of various indicators, the interaction between ABA and GA signals may play an important role in root growth compensatory effects. In summary, the results demonstrate that moderate drought stress is beneficial to root growth and yield. This conclusion is of great significance to improving our understanding of the maximum utilization of limited water resources. PMID- 29597067 TI - Involvement of an autotoxic compound in asparagus decline. AB - Asparagus (Asparagus officinalis L.) is a widely cultivated perennial veritable and can be harvested more than ten years. However, the crop quality and yield decline after a few year's cultivation, which is called "asparagus decline". Even though those asparagus plants were replaced with new young asparagus plants, the productivity and quality of the crop remain relatively low, which is known as a "asparagus replant problem". One of the possible reasons for "asparagus decline" and "asparagus replant problem" is thought to be autotoxicity of asparagus. However, the compounds involved in the autotoxicity is not clear. The objective of this study was therefore to determine the potential role of autotoxicity in the "asparagus decline" and "asparagus replant problem". An aqueous methanol extract of 10-year-asparagus-cultivated soils inhibited the growth of asparagus seedlings and other two test plants with concentration dependent manner. The result confirmed that the asparagus soils have autotoxic activity. The extract was then purified by several chromatographies with monitoring the inhibitory activity and a potent growth inhibitory substance causing the autotoxic effect was isolated. The chemical structures of the compound was determined by spectral data to be trans-cinnamic acid. trans-Cinnamic acid inhibited the growth of asparagus seedlings at concentrations greater than 10 MUM. The concentrations required for 50% growth inhibition of asparagus (IC50) were 24.1-41.6 MUM. trans Cinnamic acid accumulated 174 MUM in the 10-year-asparagus-cultivated soils, which may be enough levels to cause the growth inhibition on asparagus considering its IC50 value. Therefore, trans-cinnamic acid may contribute to the autotoxic effect of asparagus soils, and may be in part responsible for "asparagus decline" and "asparagus replant problem". PMID- 29597068 TI - Proteomic analysis of tree peony (Paeonia ostii 'Feng Dan') seed germination affected by low temperature. AB - Seed germination is a critical process that is influenced by various factors. In the present study, the effect of low temperature (4 degrees C) on tree peony seed germination was investigated. Compared to seeds maintained at 25 degrees C, germination was inhibited when seeds were kept at 4 degrees C. Furthermore, low temperature exposure of seeds resulted in a delay in water uptake, starch degradation, and soluble sugar consumption and a subsequent increase in soluble protein levels. Two-dimensional gel electrophoresis (2-DE) proteomic analysis identified 100 protein spots. Comparative analysis indicated that low-temperature exposure apparently mainly affected glycolysis and the tricarboxylic acid (TCA) cycle, while also significantly affecting proteometabolism-related factors. Moreover, low-temperature exposure led to the induction of abscisic acid, whereas the gibberellin pathway was not affected. Further comparison of the two temperature conditions showed that low-temperature exposure delays carbohydrate metabolism, adenosine triphosphate (ATP) production, respiration, and proteolysis and increases defense response factors. To further examine the obtained proteomic findings, four genes were evaluated by quantitative polymerase chain reaction (qPCR). The obtained transcriptional results for the GAPC gene coincided with the translational results, thus further suggesting that the delay in glycolysis may play a key role in low-temperature-induced inhibition of seed germination. However, the other three genes examined, which included FPP synthase, PCNT115, and endochitinase, showed non-correlative transcriptional and translational profiles. Our results suggest that the exposure of tree peony seeds to low temperature results in a delay in the degradation of starch and other metabolites, which in turn affects glycolysis and some other processes, thereby ultimately inhibiting seed germination. PMID- 29597069 TI - A NIR sensor for cyanide detection and its application in cell imaging. AB - A novel 'D-pi-A' sensor 1 has been designed and prepared via the condensation reaction of 3-ethyl-2-methyl-1,3-benzothiazol-3-ium iodide and 5-nitro-o vanillin. Upon treatment with cyanide, sensor 1 exhibited a significant near infrared (NIR) fluorescence quenching at 663nm. The MS, IR, 1H NMR and DFT methods confirmed that the response of 1 to cyanide is due to the nucleophilic addition reaction, which results in the inhibition of the Intramolecular Charge Transfer (ICT) process in the sensor. Furthermore, sensor 1 was used for the determination of CN- in HeLa cells. PMID- 29597070 TI - Raman and FTIR spectroscopic studies on two hydroxylated tung oils (HTO) bearing conjugated double bonds. AB - Tung oil (TO) was used as a model compound to study two hydroxylated tung oils (HTO), prepared from TO by either aminolysis (HTO-am) or alcoholysis (HTO-al). Main bands in Raman and FTIR spectra were initially assigned based on the detailed analysis of the compound spectra before and after exposure to elevated temperature (200 degrees C). The effect of heat treatment in air on spectral bands, and especially on the changes associated with double bonds, were then investigated. In the present work, changes in spectral bands due to heat treatment were compared with those revealed in the previous work of others. The results show that the conjugated triene structure of TO has been retained during alcoholysis and aminolysis, to yield the HTOs studied; yet the change of the triene structure caused by heating is different among the three samples; the H bonding strength between OH and CO in HTO-am is higher than that in HTO-al; the changes in HTO vOH and vCO bands in FTIR caused by the present heat treatment were significant; for TO, there is a big difference between changes in spectra as caused by thermal exposure, compared to those caused by ageing under UV light or exposure to a catalyst. The present work has laid additional groundwork for further study of the reactions of such triply conjugated double bond structures under different ageing conditions. PMID- 29597071 TI - Biomolecular imaging of 13C-butyrate with dissolution-DNP: Polarization enhancement and formulation for in vivo studies. AB - Magnetic Resonance Spectroscopy of hyperpolarized isotopically enriched molecules facilitates the non-invasive real-time investigation of in vivo tissue metabolism in the time-frame of a few minutes; this opens up a new avenue in the development of biomolecular probes. Dissolution Dynamic Nuclear Polarization is a hyperpolarization technique yielding a more than four orders of magnitude increase in the 13C polarization for in vivo Magnetic Resonance Spectroscopy studies. As reported in several studies, the dissolution Dynamic Nuclear Polarization polarization performance relies on the chemico-physical properties of the sample. In this study, we describe and quantify the effects of the different sample components on the dissolution Dynamic Nuclear Polarization performance of [1-13C]butyrate. In particular, we focus on the polarization enhancement provided by the incremental addition of the glassy agent dimethyl sulfoxide and gadolinium chelate to the formulation. Finally, preliminary results obtained after injection in healthy rats are also reported, showing the feasibility of an in vivo Magnetic Resonance Spectroscopy study with hyperpolarized [1-13C]butyrate using a 3T clinical set-up. PMID- 29597072 TI - Increased prevalence of anxiety disorders in third-generation migrants in comparison to natives and to first-generation migrants. AB - INTRODUCTION: We sought to examine the prevalence of anxiety disorders associated with migration in the first-, second- and third-generation. METHODS: The French Mental Health in the General Population cross-sectional survey interviewed 38,694 individuals using the MINI. The prevalence of lifetime anxiety disorders, and comorbidities was compared between migrants and non-migrants and by generation. All analyses were adjusted for age, sex, and income and education levels. RESULTS: In comparison to natives, pooled anxiety disorders were more common among migrants (25.3% vs. 20.7%, OR = 1.24) and among the three studied generations of migrants. Moreover, the prevalence rate of the pooled anxiety disorders was significantly higher in third-generation migrants, in comparison to first-generation (26.7% vs. 22.6%, OR = 1.14). Prevalence rates were higher in migrants for panic disorder (6.6% vs. 5.3%, OR = 1.20), general anxiety disorder (15.0% vs. 12.0%, OR = 1.24), posttraumatic stress disorder (1.0% vs. 0.6%, OR = 1.51), but not for social anxiety disorder. In comparison to natives, migrants with anxiety disorders had higher prevalence rates of suicide attempts (14.0% vs. 12.8% for natives), psychotic disorders (8.3% vs. 5.7%), unipolar depressive disorder (29.5% vs. 25.4%), bipolar disorder (5.0% vs. 4.0%), and addictive disorders (9.6% vs. 6.2% for alcohol use disorder, 8.2% vs. 4.1% for substance use disorders). CONCLUSION: Migration was associated with a higher prevalence of all anxiety disorders, in the first, second and third generation, and associated with more psychiatric comorbidities. Moreover, the prevalence increased across generations, and was significantly higher among third-generation migrants, in comparison to first-generation. PMID- 29597073 TI - p21 Activated kinase 1: Nuclear activity and its role during DNA damage repair. AB - p21-activated kinase 1 (PAK1) is a serine/threonine kinase activated by the small GTPases Rac1 and Cdc42. It is located in the chromosome 11q13 and is amplified and/or overexpressed in several human cancer types including 25-30% of breast tumors. This enzyme plays a pivotal role in the control of a number of fundamental cellular processes by phosphorylating its downstream substrates. In addition to its role in the cytoplasm, it is well documented that PAK1 also plays crucial roles in the nucleus participating in mitotic events and gene expression through its association and/or phosphorylation of several transcription factors, transcriptional co-regulators and cell cycle-related proteins, including Aurora kinase A (AURKA), polo-like kinase 1 (PLK1), the forkhead transcription factor (FKHR), estrogen receptor alpha (ERalpha), and Snail. More recently, PAK signaling has emerged as a component of the DNA damage response (DDR) as PAK1 activity influences the cellular sensitivity to ionizing radiation and promotes the expression of several genes involved in the Fanconi Anemia/BRCA pathway. This review will focus on the nuclear functions of PAK1 and its role in the regulation of DNA damage repair. PMID- 29597074 TI - The variable lymphocyte receptor as an antibody alternative. AB - Variable lymphocyte receptors (VLRs) are leucine-rich repeat proteins in jawless vertebrates that function similarly to Ig antibodies. However, VLRs possess a distinct crescent-shaped structure and modularity that results in a concave binding interface that contrasts significantly with Ig antibodies. Antigen binding interactions result in specific, high affinity VLR binding interactions with both proteins and glycans. The natural sourcing of VLRs allows for immunization strategies, while the modularity enables a whole host of protein engineering approaches including consensus scaffolds, designed libraries and directed evolution with display technologies. VLR technologies have been recently deployed for applications in cell-specific targeting, drug delivery, tumor diagnostics and even protein stabilization. It is anticipated that the VLR field will continue to emerge to provide unique solutions for targeting glycans, evolutionarily conserved proteins and cellular specificity. PMID- 29597076 TI - Genome engineering for CNS injury and disease. AB - Recent developments in genome engineering methods have advanced our knowledge of central nervous system (CNS) function in both normal health and following disease or injury. This review discusses current literature using gene editing tools in CNS disease and injury research, such as improving viral-mediated targeting of cell populations, generating new methods for genome editing, reprogramming cells into CNS cell types, and using organoids as models of development and disease. Readers may gain inspiration for continuing research into new genome engineering methods and for therapies for CNS applications. PMID- 29597075 TI - Bionanotechnology for vaccine design. AB - There have been significant advances in the design of nanostructured scaffolds for eliciting robust immune responses. One method to produce strong immune responses is to emulate the appearance of a pathogen. Since pathogens such as viruses and bacteria often display multiple copies of ligands on their surfaces, the immune system is particularly sensitive towards multivalent displays of antigens. Consequently, when designing a vaccine, it is advantageous to decorate a nanostructured surface with multiple copies of an antigen. This review highlights the design and efficacy of a diverse set of recently developed nanostructured vaccine scaffolds. PMID- 29597077 TI - Urine Cotinine level with smoking history predicts a risk of coronary artery calcification. AB - We investigated whether urine cotinine level, alone or combined with smoking status and cumulative smoking amount, could predict coronary calcium (CAC) score increase over time. The study population included 10,980 subjects. We analysed an association between CAC score increase over time and single or combined smoking related factors. Urine cotinine level of >=100 ng/mL, current or ex-smokers, and cumulative smoking amount of >=1 pack-years (PY) showed significantly higher odds ratios (ORs) for CAC score increase over time. A combination of current smokers with >10 PY and urine cotinine level of >=100 ng/mL showed the highest OR. Irrespective of smoking status and cumulative smoking amount, all combinations with urine cotinine of >=100 ng/mL showed higher ORs than other combinations with urine cotinine level of <100 ng/mL. Urine cotinine levels can be useful to predict coronary artery calcification and encourage smokers to quit smoking. PMID- 29597078 TI - Toxicological effects of cadmium and lead on two freshwater diatoms. AB - In recent years, there have been significant advances in the knowledge and understanding of the pollution attributed to effects of aquatic toxic metals on fresh water benthic diatoms. In this study, the cell growth, chlorophyll a content and superoxide dismutase activity in Halamphora veneta (Kutzing) Levkov and Surirella crumena Brebisson exposed to cadmium and lead, were investigated. Furthermore, in order to explore the potential function of H. veneta on environmental monitoring and environmental remediation, expression of two genes (psbA, psaB) and morphological analysis of H. veneta were carried out. The cells growth of H. veneta and S. crumena were generally inhibited with cadmium and lead exposure during 96 h, while cells density of H. veneta was significantly increased under the low concentration at 24 h cadmium exposure. Our results indicated that H. veneta had a certain tolerance to toxic metals at initial treated time. In addition, the significantly changes of chlorophyll a content and SOD activities in H. veneta and S. crumena indicated that both photosynthetic system and the antioxidant system in benthic diatom might play important roles on the toxic metals tolerant mechanism. Meanwhile, it can be confirmed that the diatom photosynthetic systems play roles on toxic metals resistance inferred from the gene expression of psbA and psaB in H. veneta. Finally, the results of scanning electron microscopy showed that there was a slightly deformation on cells following the cadmium exposure in H. veneta, while obvious deformation with cell greatly widened after lead exposure. The present work will be helpful to understand the effect mechanisms of toxic metal by comparing two kinds of diatom on cell inhibition, biological response and morphological changes, which will provide more information for possible use of benthic diatoms in bioremediation. PMID- 29597079 TI - Assessment of Responsiveness to Everyday Non-Noxious Stimuli in Pain-Free Migraineurs With Versus Without Aura. AB - : Migraineurs with aura (MWA) express higher interictal response to non-noxious and noxious experimental sensory stimuli compared with migraineurs without aura (MWoA), but whether these differences also prevail in response to everyday non noxious stimuli is not yet explored. This is a cross-sectional study testing 53 female migraineurs (30 MWA; 23 MWoA) who underwent a wide battery of noxious psychophysical testing at a pain-free phase, and completed a Sensory Responsiveness Questionnaire and pain-related psychological questionnaires. The MWA group showed higher questionnaire-based sensory over-responsiveness (P = .030), higher magnitude of pain temporal summation (P = .031) as well as higher monthly attack frequency (P = .027) compared with the MWoA group. Overall, 45% of migraineurs described abnormal sensory (hyper- or hypo-) responsiveness; its incidence was higher among MWA (19 of 30, 63%) versus MWoA (6 of 23, 27%, P = .012), with an odds ratio of 3.58 for MWA. Sensory responsiveness scores were positively correlated with attack frequency (r = .361, P = .008) and temporal summation magnitude (r = .390, P = .004), both regardless of migraine type. MWA express higher everyday sensory responsiveness than MWoA, in line with higher response to experimental noxious stimuli. Abnormal scores of sensory responsiveness characterize people with sensory modulation dysfunction, suggesting possible underlying mechanisms overlap, and possibly high incidence of both clinical entities. PERSPECTIVE: This article presents findings distinguishing MWA, showing enhanced pain amplification, monthly attack frequency, and over-responsiveness to everyday sensations, compared with MWoA. Further, migraine is characterized by a high incidence of abnormal responsiveness to everyday sensation, specifically sensory over-responsiveness, that was also found related to pain. PMID- 29597080 TI - Individual Variation in Pain Sensitivity and Conditioned Pain Modulation in Acute Low Back Pain: Effect of Stimulus Type, Sleep, and Psychological and Lifestyle Factors. AB - : Generalized hyperalgesia and impaired pain modulation are reported in chronic low back pain (LBP). Few studies have tested whether these features are present in the acute phase. This study aimed to test for differences in pain presentation in early-acute LBP and evaluate the potential contribution of other factors to variation in sensitivity. Individuals within 2 weeks of onset of acute LBP (n = 126) and pain-free controls (n = 74) completed questionnaires related to their pain, disability, behavior, and psychological status before undergoing conditioned pain modulation (CPM) and pain threshold (heat, cold, and pressure) testing at the back and forearm/thumb. LBP participants were more sensitive to heat and cold at both sites and pressure at the back than controls, without differences in CPM. Only those with high-pain (numeric rating scale >=4) were more sensitive to heat at the forearm and pressure at the back. Four subgroups with distinct features were identified: "high sensitivity," "low CPM efficacy," "high sensitivity/low CPM efficacy," and "low sensitivity/high CPM efficacy." Various factors such as sleep and alcohol were associated with each pain measure. Results provide evidence for generalized hyperalgesia in many, but not all, individuals during acute LBP, with variation accounted for by several factors. Specific pain phenotypes provide candidate features to test in longitudinal studies of LBP outcome. PERSPECTIVE: Sensory changes indicative of increased/decreased central processing of pain and nociceptive input presented differently between individuals with acute LBP and were related to factors such as sleep and alcohol. This may underlie variation in outcome and suggest potential for early identification of individuals with poor long-term outcome. PMID- 29597081 TI - A Comparison of the Assay Sensitivity of Average and Worst Pain Intensity in Pharmacologic Trials: An ACTTION Systematic Review and Meta-Analysis. AB - : Identifying methods to improve assay sensitivity in randomized clinical trials (RCTs) may facilitate the discovery of efficacious pain treatments. RCTs evaluating pain treatments typically use average pain intensity (API) or worst pain intensity (WPI) as the primary efficacy outcome. However, little evidence is available comparing the assay sensitivity of these 2 measures. In this systematic review and meta-analysis, we comprehensively reviewed all low back pain, osteoarthritis pain, fibromyalgia, diabetic peripheral neuropathy pain, and postherpetic neuralgia RCTs that used a parallel group design. Eligibility required: 1) primary RCT report published between 1980 and 2016, 2) comparing 1 or more active, efficacious pharmacologic pain treatment(s) with placebo, and 3) providing data on the standardized effect size (SES) for API as well as WPI for all treatment arms. Twenty-seven active versus placebo comparisons were identified in 23 eligible articles. Using a random-effects meta-analysis, API SES and WPI SES did not differ significantly (difference = -.021, 95% confidence interval = -.047 to .004, P = .12). The findings indicate that, depending on the objectives of the study, either API or WPI could be used as a primary outcome measure in clinical trials for the chronic pain conditions included in this analysis. PERSPECTIVE: Understanding the comparative assay sensitivity of API and WPI may advance pain treatment research. A meta-analysis of trials of efficacious pharmacologic treatments in 5 pain conditions did not show a statistically significant difference between the assay sensitivity of API and WPI. PMID- 29597082 TI - Prevalence and Pharmaceutical Treatment of Plantar Fasciitis in United States Adults. AB - : This study provides prevalence estimates of plantar fasciitis in U.S. adults, as well as the types and frequencies of pharmaceutical treatment specifically for this pain. Data are from the 2013 National Health and Wellness Survey, a large (n = 75,000) internet panel survey designed to approximate the adult U.S. POPULATION: Strengths of associations are determined using multivariable logistic regression. It was estimated that .85% (95% confidence interval [CI] = .77-.92) of the sample reported diagnosed plantar fasciitis with pain in the past month. Higher prevalence of plantar fasciitis was seen in women (1.19%; referent) versus men (.47%), in those aged 45 to 64 (1.33%) versus those aged 18 to 44 (.53%; referent) years, and in the obese (1.48%) versus those with a body mass <25 (.29%; referent). Prescription medications for pain were used by 41.04% of plantar fasciitis respondents, but only 6.31% attributed this use specifically to plantar fasciitis pain. Nonsteroidal anti-inflammatory drugs (4.01%) and opioids (2.21%) were the most prevalent prescription drugs used specifically for plantar fasciitis pain. Almost 70% of individuals with plantar fasciitis used over the counter (OTC) analgesics for general pain management, with OTC nonsteroidal anti inflammatory drugs being used by 49.47% and acetaminophen by 26.93% of respondents. Individuals diagnosed by medical specialists had twice the odds of using prescription drugs as those diagnosed by other providers (odds ratio = 2.12; 95% CI = 1.01-4.46). Non-Hispanic black individuals were more likely to use prescription pain medications specifically for plantar fasciitis pain than non Hispanic white individuals (odds ratio = 3.02; 95% CI = 1.05-8.70). PERSPECTIVE: The current study provides additional insights into the pain and disability associated with plantar fasciitis, as well as the pharmaceutical treatments being used for its management. Prescription as well as OTC medications are used to manage plantar fasciitis symptoms despite limited, if any, clinical trial data supporting their use. PMID- 29597083 TI - Traumatic Brain Injury and Receipt of Prescription Opioid Therapy for Chronic Pain in Iraq and Afghanistan Veterans: Do Clinical Practice Guidelines Matter? AB - : Clinical practice guidelines admonish against prescribing opioids for individuals with chronic pain and traumatic brain injury (TBI) because of increased risk for adverse outcomes, yet no studies have described opioid prescribing patterns in these higher-risk patients. Between October 2007 and March 2015, 53,124 Iraq and Afghanistan veterans with chronic pain not prescribed opioids in the previous year were followed for 1 year after completing a Comprehensive TBI Evaluation within the Department of Veterans Affairs health care facilities. Veterans reporting the most severe TBI sequelae (eg, loss of consciousness >30 minutes) were significantly more likely to receive short-term and long-term opioid therapy than those with less severe or no TBI sequelae (P values < .001). In analyses adjusted for sociodemographic characteristics, military service, pain disability, and previous nonopioid treatment modalities, veterans with moderate to severe TBI had a significantly increased risk of receiving opioid therapy. Veterans with moderate to severe TBI and comorbid post traumatic stress disorder and depression had an even greater risk of initiating long-term opioid therapy in the year after the Comprehensive TBI Evaluation (adjusted relative risk = 3.57 [95% confidence interval = 2.85-4.47]). Higher risk patients with chronic pain and TBI with mental health comorbidities may benefit from improved access to behavioral health and nonpharmacological therapies for chronic pain. PERSPECTIVE: Paradoxically, veterans with greater TBI severity and comorbid mental health burden are more likely to be prescribed opioids for chronic pain. More vulnerable veterans may benefit from improved access to behavioral health and nonpharmacological modalities for chronic pain, because of the health and safety risks of opioids. PMID- 29597084 TI - Pain Adaptability in Individuals With Chronic Musculoskeletal Pain Is Not Associated With Conditioned Pain Modulation. AB - : Healthy humans can be divided into the pain adaptive (PA) and the pain nonadaptive (PNA) groups; PA showed a greater decrease in pain rating to a cold pressor test (CPT) than PNA. This study examined if the dichotomy of pain adaptability existed in individuals with chronic musculoskeletal pain. CPTs at 2 degrees C and 7 degrees C were used to assess the status of pain adaptability in participants with either chronic nonspecific low back pain or knee osteoarthritis. The participants' potency of conditioned pain modulation (CPM) and local inhibition were measured. The strengths of pain adaptability at both CPTs were highly correlated. PA and PNA did not differ in their demographic characteristics, pain thresholds from thermal and pressure stimuli, or potency of local inhibition or CPM. PA reached their maximum pain faster than PNA (t41 = 2.76, P < .01), and had a gradual reduction of pain unpleasantness over 7 days whereas PNA did not (F6,246 = 3.01, P = .01). The dichotomy of pain adaptability exists in musculoskeletal pain patients. Consistent with the healthy human study, the strength of pain adaptability and potency of CPM are not related. Pain adaptability could be another form of endogenous pain inhibition of which clinical implication is yet to be understood. PERSPECTIVE: The dichotomy of pain adaptability was identified in healthy humans. The current study confirms that this dichotomy also exists in individuals with chronic musculoskeletal pain, and could be reliably assessed with CPTs at 2 degrees C and 7 degrees C. Similar to the healthy human study, pain adaptability is not associated with CPM, and may reflect the temporal aspect of pain inhibition. PMID- 29597085 TI - Yttrium-doped iron oxide magnetic adsorbent for enhancement in arsenic removal and ease in separation after applications. AB - Arsenic contamination is one of serious environmental problems in the world. In this study, an innovative yttrium-doped iron oxide magnetic adsorbent was synthesized through a simple precipitation method for better arsenic decontamination and ease in separation after the application. The adsorbent with a rough surface and porous structure was aggregated of nano-sized irregular particles after heat-drying procedure. The point of zero charge value of the adsorbent was about 7.0, giving good performance on the arsenate removal at weakly acidic and neutral conditions. The thermal gravimetric analysis, X-ray powder diffraction and X-ray photoelectron spectroscopy studies demonstrated that hydroxyl groups from goethite and amorphous species of the adsorbent were mainly responsible for the arsenic adsorption. The adsorption equilibrium of arsenate and arsenite was respectively established in 24 and 4 h. The maximum adsorption capacities of As(V) and As(III) at pH 7.0 were 170.48 and 84.22 mg-As/g, respectively. The better fit by the Freundlich isotherm indicated the mechanism of multi-layer adsorption for the removal. Our study demonstrated that the material would be suitable for treating arsenic-containing water with higher efficiency and ease in use. PMID- 29597087 TI - Spatiotemporal evolution of the remotely sensed global continental PM2.5 concentration from 2000-2014 based on Bayesian statistics. AB - PM2.5 pollution is threatening human health and quality of life, especially in some densely populated regions of Asia and Africa. This paper used remotely sensed annual mean PM2.5 concentrations to explore the spatiotemporal evolution of global continental PM2.5 pollution from 2000 to 2014. The work employed an improved Bayesian space-time hierarchy model combined with a multiscale homogeneous subdivision method. The statistical results quantitatively demonstrated a 'high-value increasing and low-value decreasing' trend. Areas with annual PM2.5 concentrations of more than 70MUg/m3 and less than 10MUg/m3 expanded, while areas with of an annual PM2.5 concentrations of 10-25MUg/m3 shrank. The most heavily PM2.5-polluted areas were located in northwest Africa, where the PM2.5 pollution level was 12.0 times higher than the average global continental level; parts of China represented the second most PM2.5-polluted areas, followed by northern India and Saudi Arabia and Iraq in the Middle East region. Nearly all (96.50%) of the highly PM2.5-polluted area (hot spots) had an increasing local trend, while 68.98% of the lightly PM2.5-polluted areas (cold spots) had a decreasing local trend. In contrast, 22.82% of the cold spot areas exhibited an increasing local trend. Moreover, the spatiotemporal variation in the health risk from exposure to PM2.5 over the global continents was also investigated. Four areas, India, eastern and southern China, western Africa and central Europe, had high health risks from PM2.5 exposure. Northern India, northeastern Pakistan, and mid-eastern China had not only the highest risk but also a significant increasing trend; the areas of high PM2.5 pollution risk are thus expanding, and the number of affected people is increasing. Northern and central Africa, the Arabian Peninsula, the Middle East, western Russia and central Europe also exhibited increasing PM2.5 pollution health risks. PMID- 29597086 TI - The use of longitudinal cohorts for studies of dengue viral pathogenesis and protection. AB - In this review, we describe how longitudinal prospective community-based, school based, and household-based cohort studies contribute to improving our knowledge of viral disease, focusing specifically on contributions to understanding and preventing dengue. We describe how longitudinal cohorts enable measurement of essential disease parameters and risk factors; provide insights into biological correlates of protection and disease risk; enable rapid application of novel biological and statistical technologies; lead to development of new interventions and inform vaccine trial design; serve as sentinels in outbreak conditions and facilitate development of critical diagnostic assays; enable holistic studies on disease in the context of other infections, comorbidities, and environmental risk factors; and build research capacity that strengthens national and global public health response and disease surveillance. PMID- 29597088 TI - LDR reverses DDP resistance in ovarian cancer cells by affecting ERCC-1, Bcl-2, Survivin and Caspase-3 expressions. AB - BACKGROUND: Ovarian cancer is the most frequent cause of death resulting from malignant gynecological tumors. After surgical intervention, cisplatin (DDP) is a major chemotherapy drug for ovarian cancer, but the ovarian cancer cells tend to develop DDP resistance in the clinical setting. Tumor cells are sensitive to low dose radiation (LDR). However, how the LDR therapy improves the effects of chemotherapy drugs on ovarian cancer is not well understood. This study aimed to explore this issue. METHODS: The SKOV3/DDP cells were divided into 3 groups, including low-dose group, conventional-dose group, and control group (no radiation). Cell counting kit-8 assay was performed to measure cell proliferation. Flow cytometric analysis was then utilized to quantify the apoptosis with classical Annexin V/propidium iodide co-staining. And Real-time quantitative PCR and western blot were eventually used to analyze the mRNA and protein levels of excision repair cross complementing-group 1 (ERCC1), B-cell lymphoma 2 (Bcl-2), Survivin and Caspase-3, respectively. RESULTS: The IC50 value of DDP in the low-dose group was significantly lower compared with the other two groups. Compared with the conventional-dose group and control group, LDR treatment resulted in significantly more apoptosis. Besides, LDR treatment significantly decreased the mRNA and protein expression of ERCC1, Bcl-2, and Survivin, and enhanced the mRNA and protein expression of Caspase-3 compared with the other two groups. CONCLUSIONS: LDR reversed DDP resistance in SKOV3/DDP cells possibly by suppressing ERCC1, Bcl-2, and Survivin expressions, and increasing Caspase-3 expression.

AB - Pancreatic cancer is considered as one of the most lethal type of cancer with a poor 5-year survival rate. Cancer metastasis represents one of the primary cause which limits therapy against this disease. Current chemotherapeutic approaches are largely ineffective, thus calling for the development of alternative strategies to combat this disease. In this regard, numerous studies have reported the anticancer effect of curcumin in different types of cancer including pancreatic cancer. However, low aqueous solubility, poor stability and decreased bioavailability associated with native curcumin holds back its use in clinical settings. In order to enhance its therapeutic value, polymeric nanoparticles (NPs) represent an ideal delivery system. Further, surface modification of NPs with various macromolecules, such as chitosan and polyethylene glycol (PEG) holds tremendous potential for improving the bioavailability and circulation time of native drug in the blood. In the present study, we have explored the above approach to formulate curcumin-loaded Poly d,l-lactide-co-glycolide (PLGA) NPs and further surface coated it with chitosan and PEG (CNPs) with anticipation to reduce the limitations associated with native curcumin delivery for achieving an optimum therapeutic effect. Results revealed that NPs are of nanometre range having smooth and spherical surface morphology and with an efficient loading of curcumin. In vitro, cellular studies revealed superior cytotoxicity, enhanced anti-migratory, anti-invasive and apoptosis-inducing ability of CNPs in metastatic pancreatic cancer in comparison to a native counterpart. Thus, we anticipate that the results from these studies can open up novel options for the treatment of pancreatic cancer.

AB - Radiotherapy is one of the common treatments for esophageal squamous cell carcinoma (ESCC). Yet, local recurrence led by radioresistance is still not solved. Lobaplatin (LBP) is known to have powerful clinical anti-tumor activities in various tumors, but its effect in radiotherapy is rarely studied. Here we report that LBP is a promising radiosensitizer for ESCC. We treated ESCC cells with LBP and radiation, both separately and in combination. Untreated cells were set as control groups. We found that LBP inhibited ESCC cell growth and enhanced their radiosensitivity. LBP also impeded the tumor growth in vivo. LBP combined with radiation significantly increased ESCC cell apoptosis. Meanwhile, LBP obviously decreased the expression of cancer stem cells biomarker CD271 both in vitro and in vivo. The molecular mechanism was related to the downregulation of Bcl-2/Bax ratio, PI3K and p-AKT (Ser473) expression. Taken together, our findings indicated that LBP could enhance the radiosensitivity of ESCC cells by increasing radiation-induced apoptosis, attenuating cancer stemness and inhibiting PI3K/AKT pathway. These results provide a foundation for the combined therapy of radiation and LBP for ESCC in clinical practice.

(roselle) belonging to the Malvaceae family is widely grown in many countries. This plant is often used in the traditional medicine being rich in phytochemicals like polyphenols especially anthocyanins, polysaccharides and organic acids thus having enormous prospective in modern therapeutic uses. The study aimed to review and document all the available evidence and information about the calyces of Hibiscus sabdariffa (roselle) with the special focus on their nutritional composition, bioactive constituents and therapeutic uses. The electronic database was searched up to 2017, using keywords Hibiscus sabdariffa, chemical constituents of roselle, therapeutic uses of roselle. Journals, books and conference proceedings were also searched. The review provides valuable information about the nutraceutical component of Hibiscus sabdariffa L. and their utilization for curing various degenerative diseases like hypertension, hyperlipidemia, cancer and other inflammatory diseases of liver and kidney. Their toxicological effects have also been discussed from a safety point of view. Most studies supported and provided the scientific basis for the statement that Hibiscus sabdariffa and their active constituents play an important role in the prevention of chronic and degenerative diseases that are associated with oxidative stress. Our study suggests, that good research is needed, to establish a potential strategy that can balance the pharmacological and toxic effects of roselle and standardized fingerprint of Hibiscus sabdariffa is required internationally for quality control.

AB - This study aims to explore the roles and related mechanisms of HuR in osteosarcoma (OS) cells migration, invasion, stemness and chemotherapeutical sensitivity. Here, we found that HuR exhibited higher level in OS tissues compared with the adjacent normal tissues. Knockdown of HuR with lentivirus infection suppressed OS cells migration and invasion, and thus the epithelial mesenchymal transition (EMT) process. Additionally, HuR knockdown inhibited OS cells stemness. Mechanistically, YAP was identified as a direct target of HuR in OS cells, and HuR knockdown decreased its expression. Moreover, YAP transcriptional activity was attenuated by HuR knockdown, and RNA immunization co precipitation (RIP) assay showed that HuR directly bound with YAP. Importantly, YAP overexpression rescued the inhibition of HuR knockdown on OS cells migration, invasion and stemness. Furthermore, HuR knockdown enhanced adriamycin sensitivity in OS cells, this effect was attenuated by YAP overexpression too. Importantly, HuR and YAP expression was positively correlated in OS tissues. Therefore, HuR acts as a tumor promoter by enhancing YAP expression in OS cells. PMID- 29597093 TI - Arginine: Challenges and opportunities of this two-faced molecule in cancer therapy. AB - Numerous antitumor therapies have been developed based on the differences in cells' metabolisms. Regarding the important role of arginine (Arg) in the regulation of multiple metabolic and signaling pathways, its deprivation has been proposed as a good strategy for tumor regression in tumors with defected Arg metabolic enzymes like argininosuccinate synthase 1 (ASS1). However, modulatory effect of Arg on various cancers is also a controversial issue. Therefore, this review article intends to address some of the challenges faced by Arg deprivation method as well as Arg administration for cancer therapy. PMID- 29597095 TI - Speech and language delay in a patient with WDR4 mutations. AB - Primordial dwarfism (PD) is mainly characterized by growth deficiency with heterogeneous phenotypes. A group of genes are known to be associated with PD or PD-related syndrome. WD repeat domain 4 (WDR4) is recently reported to be responsible for PD. Here we report a 6-year-old boy from a non-consanguineous couple with motor and speech delay as well as intellectual disability. Whole exome sequencing (WES) identified a missense mutation (NM_033661.4:c.491A > C; p.(Asp164Ala)) and a small insertion (NM_033661.4:c.940dupC; p.(Leu314Profs*16)) of WDR4 in this patient. Two novel mutations confirmed by Sanger sequencing are from father and mother respectively according to a recessive inheritance pattern. Asp164Ala located in functional region is predicted to be deleterious by two kinds of algorithm. The small insertion causing a frameshift mutation leads to truncated protein. In this study, we present two novel WDR4 mutations responsible for PD in a 6-year-old patient, expanding the molecular and phenotype spectrum of WDR4-related PD. PMID- 29597094 TI - Membrane properties that shape the evolution of membrane enzymes. AB - Spectacular recent progress in structural biology has led to determination of the structures of many integral membrane enzymes that catalyze reactions in which at least one substrate also is membrane bound. A pattern of results seems to be emerging in which the active site chemistry of these enzymes is usually found to be analogous to what is observed for water soluble enzymes catalyzing the same reaction types. However, in light of the chemical, structural, and physical complexity of cellular membranes plus the presence of transmembrane gradients and potentials, these enzymes may be subject to membrane-specific regulatory mechanisms that are only now beginning to be uncovered. We review the membrane specific environmental traits that shape the evolution of membrane-embedded biocatalysts. PMID- 29597096 TI - A sustainable solution for the activities of the European network for surveillance of congenital anomalies: EUROCAT as part of the EU Platform on Rare Diseases Registration. AB - The European Commission through its Directorates-General Joint Research Centre (DG JRC) and Health and Food Safety (DG SANTE) is developing the European Platform on Rare Diseases Registration (EU RD Platform) with the objective to set European-level standards for data collection and data sharing. In the field of rare diseases the EU RD Platform will be a source of information on available rare disease patient data with large transnational European coverage. One main function of the EU RD Platform is to enable interoperability for the >600 existing RD registries in Europe. The second function is to offer a sustainable solution for two large European surveillance networks: European Surveillance of Congenital Anomalies (EUROCAT) and Surveillance of Cerebral Palsy in Europe (SCPE). EUROCAT is European network of population-based registries for the epidemiological surveillance of congenital anomalies. It covers about one third of the European birth population. The Central Database contains about 800,000 cases with congenital anomalies among livebirths, stillbirths and terminations of pregnancy, reported using the same standardised classification and coding. These high quality data enables epidemiological surveillance of congenital anomalies, which includes estimating prevalence, prenatal diagnosis and perinatal mortality rates and the detection of teratogenic exposures among others. The network also develops recommendations for primary prevention in the Rare Diseases National Plans for medicinal drugs, food/nutrition, lifestyle, health services, and environmental pollution. The network has received the European Commission's support since its inception. In order to offer a sustainable solution for the continuation of EUROCAT activities, it was agreed that EUROCAT would become part of the EU RD Platform. In 2015, the European level-coordination activities and the Central Database were transferred to the DG JRC, where the JRC-EUROCAT Central Registry is now located. This paper describes the functioning of EUROCAT in the new setting, and gives an overview of the activities and the organisation of the JRC-EUROCAT Central Registry. PMID- 29597097 TI - Performance evaluation of four type-specific commercial assays for detection of herpes simplex virus type 1 antibodies in a Middle East and North Africa population. AB - BACKGROUND: The number of diagnostic assays for the detection of herpes simplex virus type 1 (HSV-1) antibodies has increased over the years. However, their performance characteristics could vary among global populations. OBJECTIVE: To investigate performance of two commercial ELISA kits, HerpeSelect(r) 1 ELISA and Euroimmun Anti-HSV-1 (gC1) ELISA (IgG); and two commercial immunoblot (IB)/Western blot (WB) assays, HerpeSelect(r) 1 and 2 Immunoblot IgG, and Euroimmun Anti-HSV-1/HSV-2 gG2 Euroline-WB (IgG/IgM); in detecting HSV-1 antibodies in a Middle East and North Africa (MENA) population. STUDY DESIGN: Blood specimens were collected from blood donors in Doha, Qatar, June 2013-2016. Twenty specimens were randomly selected from 10 MENA nationalities (Egypt, Iran, Jordan, Lebanon, Pakistan, Palestine, Qatar, Sudan, Syria, and Yemen; total = 200), and tested for HSV-1 antibodies. RESULTS: Across all six comparisons between assays, positive percent agreement ranged between 95.7% (95% CI: 91.4 98.3%) and 100.0% (95% CI: 97.8-100.0%). Negative percent agreement ranged between 86.2% (95% CI: 68.3-96.1%) and 96.2% (95% CI: 80.4-99.9%). Overall percent agreement ranged between 95.7% (95% CI: 91.7-97.8%) and 99.4% (95% CI: 96.7-99.9%). Cohen's kappa statistic ranged between 0.84 (95% CI: 0.73-0.95) and 0.98 (95% CI: 0.93-1.00). Compared against IB/WB, HerpeSelect(r) and Euroimmun had sensitivities and specificities >96% and >86%, respectively. Positive and negative predictive values were >97% and >83%, respectively. CONCLUSION: The assays showed excellent concordance with one another, and with a high kappa statistic. The ELISA kits demonstrated robust diagnostic performance compared to the IB/WB assays. These findings support the assays' utility in clinical diagnosis and research in MENA populations. PMID- 29597098 TI - Long-term survival after pulmonary resections for multiple metastases from gastric cancer: A case report. AB - INTRODUCTION: The prognosis of pulmonary resection for metastatic gastric cancer is poor even though solitary metastasis. Long-term survival after pulmonary resections for multiple pulmonary metastases from gastric cancer is extremely rare. CASE PRESENTATION: The patient was 67-year old man who underwent a distal gastrectomy for early gastric cancer. Wedge resections of the right upper and lower lobes and right lower lobectomy were performed for metastases from gastric cancer at 29 months and 55 months after the gastrectomy, respectively. As of 96 months after the first pulmonary metastasectomy, this patient continues to be recurrence-free. DISCUSSION: Multiple pulmonary metastases after gastrectomy are not considered candidates for surgery. Although systemic chemotherapy is the standard therapy for metastatic gastric cancer, the prognosis is extremely poor. In this case with favorable prognostic factors, such as long disease-free intervals or absence of extrapulmonary metastasis, pulmonary metastasectomy could be a therapeutic option in patients despite the presence of multiple pulmonary metastases. CONCLUSIONS: Our case suggests that even in cases involving multiple pulmonary metastases, pulmonary metastasectomy might be an effective therapeutic option that can improve survival. PMID- 29597099 TI - Electrochemically mediated polymerization for highly sensitive detection of protein kinase activity. AB - Protein kinases play a pivotal role in cellular regulation and signal transduction, the detection of protein kinase activity and inhibition is therefore of great importance to clinical diagnosis and drug discovery. In this work, a novel electrochemical platform using the electrochemically mediated polymerization as an efficient and cost-effective signal amplification strategy is described for the highly sensitive detection of protein kinase activity. This platform involves 1) the phosphorylation of substrate peptide by protein kinase, 2) the attachment of alkyl halide to the phosphorylated sites via the carboxylate Zr4+-phosphate chemistry, and 3) the in situ grafting of electroactive polymers from the phosphorylated sites through the electrochemically mediated atom transfer radical polymerization (eATRP) at a negative potential, in the presence of the surface-attached alkyl halide as the initiator and the electroactive tag conjugated acrylate as the monomer, respectively. Due to the electrochemically mediated polymerization, a large number of electroactive tags can be linked to each phosphorylated site, thereby greatly improving the detection sensitivity. This platform has been successfully applied to detect the activity of cAMP dependent protein kinase (PKA) with a detection limit down to 1.63 mU mL-1. Results also demonstrate that it is highly selective and can be used for the screening of protein kinase inhibitors. The potential application of our platform for protein kinase activity detection in complex biological samples has been further verified using normal human serum and HepG2 cell lysate. Moreover, our platform is operationally simple, highly efficient and cost-effective, thus holding great potential in protein kinase detection and inhibitor screening. PMID- 29597100 TI - Cellulosome assembly: paradigms are meant to be broken! AB - Cohesin-Dockerin interactions are at the core of cellulosomal assembly and organization. They are highly specific and form stable complexes, allowing cellulosomes to adopt distinct conformations. Each cellulosomal system seems to have a particular organizational strategy that can vary in complexity according to the nature of its Cohesin-Dockerin interactions. Hence, several efforts have been undertaken to reveal the mechanisms that govern the specificity, affinity and flexibility of these protein-protein interactions. Here we review the most recent studies that have focused on the structural aspects of Cohesin-Dockerin recognition. They reveal an ever-increasing number of subtle intricacies suggesting that cellulosome assembly is more complex than was initially thought. PMID- 29597102 TI - Communication, compassion, and computers: Adolescents' and adults' evaluations of online and face-to-face deception. AB - We explored Canadian adolescents', emergent adults', and adults' understandings of deception in computer mediated communication (CMC) compared to face to face (FtF). Participants between 13 and 50 years read vignettes of different types of questionable behaviour that occurred online or in real life, and were asked to judge whether deception was involved, and the acceptability of the behaviour. Age groups evaluated deception similarly; however, adolescents held slightly different views from adults about what constitutes deception, suggesting that the understanding of deception continues to develop into adulthood. Furthermore, CMC behaviour was rated as more deceptive than FtF in general, and participants scoring higher on compassion perceived vignettes to be more deceptive. This study is a step towards better understanding the relationships between perceptions of deception across adolescence into adulthood, mode of communication, and compassion, and may have implications for how adults communicate with youth about deception in CMC and FtF contexts. PMID- 29597101 TI - Mother-to-child transmission of hepatitis C virus. AB - Hepatitis C virus (HCV) infection is a worldwide health problem. Based on results of a serosurvey, global prevalence is estimated to be 2,5%, and women account for about 35.8% of the cases. For pregnant women the prevalence is lower and showed a range between 0.24% to 4.3%. Sinse mechanisms and timing of mother to child transmission are not fully understood, efforts are made to assess and understand its risk factors. The purpose of this review was to synthesize the evidence about the mother-to-child transmission of hepatitis C virus and review its risk factors. PMID- 29597103 TI - The role of observed autonomy support, reciprocity, and need satisfaction in adolescent disclosure about friends. AB - Although research increasingly addresses the role of parenting in fostering adolescent disclosure, most research relied on self-report measures of parenting and did not address the role of autonomy support. In the present observational study (conducted in Belgium), with 62 mother-adolescent dyads (mean age mothers = 44 years; mean age adolescents = 14 years; 77% of adolescents female), we rated mothers' provision of autonomy support during a 10-minute conversation about friendships. We found that observed maternal autonomy support was related positively to adolescents' degree of and volitional reasons for disclosure about friends. These associations were mediated by observed non-verbal reciprocity during the conversation and by adolescent satisfaction of their needs for autonomy and relatedness. Mothers' autonomy-support and mother-adolescent reciprocity also predicted mothers' own psychological need satisfaction and conversation pleasure. The relevance of the findings for adolescent autonomy and disclosure are discussed. PMID- 29597104 TI - Development of a coping intervention to improve traumatic stress and HIV care engagement among South African women with sexual trauma histories. AB - This paper describes the development and preliminary trial run of ImpACT (Improving AIDS Care after Trauma), a brief coping intervention to address traumatic stress and HIV care engagement among South African women with sexual trauma histories. We engaged in an iterative process to culturally adapt a cognitive-behavioral intervention for delivery within a South African primary care clinic. This process involved three phases: (a) preliminary intervention development, drawing on content from a prior evidence-based intervention; (b) contextual adaptation of the curriculum through formative data collection using a multi-method qualitative approach; and (c) pre-testing of trauma screening procedures and a subsequent trial run of the intervention. Feedback from key informant interviews and patient in-depth interviews guided the refinement of session content and adaptation of key intervention elements, including culturally relevant visuals, metaphors, and interactive exercises. The trial run curriculum consisted of four individual sessions and two group sessions. Strong session attendance during the trial run supported the feasibility of ImpACT. Participants responded positively to the logistics of the intervention delivery and the majority of session content. Trial run feedback helped to further refine intervention content and delivery towards a pilot randomized clinical trial to assess the feasibility and potential efficacy of this intervention. PMID- 29597105 TI - Experimental and simulation research on the screening effect of the pixelated CZT imaging detector. AB - Massive efforts have been made to investigate the characteristics of the CdZnTe detector under different extreme conditions. In this paper, we experimented with different radiation sources to investigate the imaging screening effect of the pixelated CdZnTe detector under ultrahigh irradiance. A donut-shaped irradiation image was obtained due to the increase in the X-ray tube current or the tube voltage. Moreover, statistical data revealed that the total count of all pixels was not significantly different, while the event-count of irradiated area pixels decreased significantly. A consequence of the screening effect was that the event counts redistributed among pixels that are located in the irradiated area, while the inner electric field was distorted. This leads to the catastrophic performance degradation of the central pixels. According to the Poisson equation, we developed a theoretical model of the CdZnTe detector using the finite element software COMSOL to enable an in-depth investigation of carrier collection in the CdZnTe crystal. A comparison between the simulations and the test results showed that pixels in the central irradiated area are completely screened under the ultrahigh irradiance because of the emergence of the relatively higher potential region, which can distort the electron drift path. Furthermore, the photon generated signal can be collected only partly at the edge of the irradiated area, which was relatively stable because the collection area in the CdZnTe volume was relatively limited. The imaging results deduced from the simulations are well consistent with the experimental data. PMID- 29597106 TI - Biological nitrogen removal using soil columns for the reuse of reclaimed water: Performance and microbial community analysis. AB - The main aim of this study was to remove nitrogen compounds from reclaimed water and reuse the water in semi-arid riverine lake systems. In order to assess the nitrogen removal efficiencies in different natural environments, laboratory scale column experiments were performed using sterilized soil (SS), silty clay (SC), soil with submerged plant (SSP) and biochar amendment soil (BCS). The initial concentration of NO3--N and the flow rate was maintained constant at 15 mg L-1 and 0.6 +/- 0.1 m d-1, respectively. Among the tested columns, both SSP and BCS were able to achieve NO3--N levels <0.2 mg L-1 in the treated reclaimed water. The results from bacterial community structure analysis, using 454 pyrosequencing of 16s rRNA genes, showed that the dominant denitrifier was Bacillus at the genera level. PMID- 29597107 TI - The effect of bacterial and archaeal populations on anaerobic process fed with mozzarella cheese whey and buttermilk. AB - Dairy wastes can be conveniently processed and valorized in a biorefinery value chain since they are abundant, zero-cost and all year round available. For a comprehensive knowledge of the microbial species involved in producing biofuels and valuable intermediates from dairy wastes, the changes in bacterial and archaeal population were evaluated when H2, CH4 and chemical intermediates were produced. Batch anaerobic tests were conducted with a mixture of mozzarella cheese whey and buttermilk as organic substrate, inoculated with 1% and 3% w/v industrial animal manure pellets. The archaeal methanogens concentration increased in the test inoculated at 3% (w/v) when H2 and CH4 production occurred, being 1 log higher than that achieved in the test inoculated at 1% (w/v). Many archaeal species, mostly involved in the production of CH4, were identified by sequencing denaturing gradient gel electrophoresis (DGGE) bands. Methanoculleus, Methanocorpusculum and Methanobrevibacter genera were dominant archaea involved in the anaerobic process for bioenergy production from mozzarella cheese whey and buttermilk mixture. PMID- 29597108 TI - Biological approaches to tackle heavy metal pollution: A survey of literature. AB - Pollution by heavy metals has been identified as a global threat since the inception of industrial revolution. Heavy metal contamination induces serious health and environmental hazards due to its toxic nature. Remediation of heavy metals by conventional methods is uneconomical and generates a large quantity of secondary wastes. On the other hand, biological agents such as plants, microorganisms etc. offer easy and eco-friendly ways for metal removal; hence, considered as efficient and alternative tools for metal removal. Bioremediation involves adsorption, reduction or removal of contaminants from the environment through biological resources (both microorganisms and plants). The heavy metal remediation properties of microorganisms stem from their self defense mechanisms such as enzyme secretion, cellular morphological changes etc. These defence mechanisms comprise the active involvement of microbial enzymes such as oxidoreductases, oxygenases etc, which influence the rates of bioremediation. Further, immobilization techniques are improving the practice at industrial scales. This article summarizes the various strategies inherent in the biological sorption and remediation of heavy metals. PMID- 29597109 TI - Dispersive liquid-liquid microextraction for the quantification of venlafaxine in environmental waters. AB - The present work describes a new methodology for the detection of the antidepressant venlafaxine (VEN) in aquatic environments using dispersive liquid liquid microextraction followed by high performance liquid chromatography with fluorescence detection (DLLME-HPLC-FLD). The method developed is fast, low cost, easy to apply, uses a small volume of organic solvents and allows the simultaneous extraction of various samples. The DLLME-HPLC-FLD method presented a linearity range from 25 to 1500 ng L-1, a detection limit of 24.2 +/- 0.2 ng L-1, and an enrichment factor of 75 +/- 4. Recovery tests using solutions of NaCl and humic acids showed that ionic strength and organic matter do not influence the efficiency of the extraction, with extraction recoveries above 77%. Finally, the optimized method was applied to the analysis of water samples from different origins and VEN was only detected in one water sample obtained from a waste water treatment plant (WWTP), which had a concentration of 175 +/- 5 ng L-1. Recovery tests performed in environmental aquatic samples demonstrated that the developed extraction procedure is not influenced by the complex water matrices, with results ranging from 76 to 93%. PMID- 29597110 TI - A comparative study of longitudinal dispersion models in rigid vegetated compound meandering channels. AB - Releasing and mixing of pollutants in rivers can cause serious threats for downstream users. Longitudinal dispersion is an important factor in describing pollutant transport process in rivers. The focus of this study is on the effect of floodplain rigid vegetation characteristics including its arrangement, density and relative depth (the ratio of the flow depth in the main channel to that over floodplain) on flow and longitudinal dispersion coefficient in a meandering channel with compound cross section. Digital image processing technique was used to measure the tracer concentration. Sequential images were continuously captured at seven sections downstream of release point. PVC cylinders were installed over the floodplain to simulate rigid vegetation in tandem and random arrangements. Acoustic Doppler Velocimeter (Micro-ADV) was used to measure 3-D velocity components. The results showed that roughening the flood plain with stems increases the longitudinal flow velocity and Reynolds shear stress in the main channel, while these parameters decrease in the flood plain compared to non vegetated cases. As a result, in the presence of rigid vegetation, the travel time decreases in the main channel up to 20% compared to non-vegetated conditions. As the relative flow depth increases, the dimensionless longitudinal dispersion coefficient, K/U*H, decreases up to 74%. Also, the dimensionless longitudinal dispersion coefficient increases up to 38% with stem density in a specific relative flow depth of Dr = 0.11. Finally, a comparison has been made between laboratory data and some well-known previously reported models. Later, the most accurate equations are presented for predicting the longitudinal dispersion coefficient in rigid vegetated compound meandering channels. The results of the present study reveal that rigid vegetation over flood plain can be used as an alternative method in river rehabilitation projects for environmental management purposes. PMID- 29597111 TI - Improving fire season definition by optimized temporal modelling of daily human caused ignitions. AB - Wildfire suppression management is usually based on fast control of all ignitions, especially in highly populated countries with pervasive values-at risk. To minimize values-at-risk loss by improving response time of suppression resources it is necessary to anticipate ignitions, which are mainly caused by people. Previous studies have found that human-ignition patterns change spatially and temporally depending on socio-economic activities, hence, the deployment of suppression resources along the year should consider these patterns. However, full suppression capacity is operational only within legally established fire seasons, driven by past events and budgets, which limits response capacity and increases damages out of them. The aim of this study was to assess the temporal definition of fire seasons from the perspective of human-ignition patterns for the case study of Spain, where people cause over 95% of fires. Humans engage in activities that use fire as a tool in certain periods within a year, and in locations linked to specific spatial factors. Geographic variables (population, infrastructures, physiography and land uses) were used as explanatory variables for human-ignition patterns. The changing influence of these geographic variables on occurrence along the year was analysed with day-by-day logistic regression models. Daily models were built for all the municipal units in the two climatic regions in Spain (Atlantic and Mediterranean Spain) from 2002 to 2014, and similar models were grouped within continuous periods, designated as ignition based seasons. We found three ignition-based seasons in the Mediterranean region and five in the Atlantic zones, not coincidental with calendar seasons, but with a high degree of agreement with current legally designated operational fire seasons. Our results suggest that an additional late-winter-early-spring fire season in the Mediterranean area and the extension of this same season in the Atlantic zone should be re-considered for operational purposes in the future. PMID- 29597112 TI - We cannot change the past, but we can change its meaning. A randomized controlled trial on the effects of self-help imagery rescripting on depression. AB - BACKGROUND: Imagery rescripting is a psychotherapeutic technique that aims to ameliorate negative emotions by altering (i.e., rescripting) inner representations of negative memories and images. Although the treatment was initially developed for traumatized individuals, face-to-face interventions have yielded promising results for patients with other diagnoses as well. The present study explored the feasibility and efficacy of the approach when used as a self help intervention for depression. METHOD: A total of 127 individuals with diagnosed depression were randomly allocated to either a wait-list control condition or received a brief or long version of a manual teaching imagery rescripting. Six weeks after inclusion, patients were invited to participate in the post assessment. The Beck Depression Inventory (BDI-II) served as the primary outcome (registered at ClinicalTrials.gov (NCT03299127). RESULTS: The long version was superior to the wait-list control condition on the BDI-II, self esteem, and quality of life at a medium effect size. No effects emerged for anxiety. No significant between-group differences were found for the brief version. Moderation analyses indicated that the self-help approach seems particularly beneficial for those scoring high on symptoms, willingness to change, and expectancy (baseline). Most patients indicated they would use the technique in the future. DISCUSSION: The efficacy of imagery rescripting was confirmed when applied via self-help. Use of the long form of the manual is recommended. Future studies are needed to ascertain whether treatment effects are sustained over time. PMID- 29597113 TI - Estimation of radiocesium dietary intake from time series data of radiocesium concentrations in sewer sludge. AB - After the Fukushima accident, it became important to determine the quantity of radionuclide ingested by inhabitants. The most common methods currently used to obtain such data are the "market basket" (MB) and "duplicate" (DP) methods. However, it is difficult to conduct monitorings using these methods with sufficient frequency as they are high cost and time-consuming. The present study proposes a new method to estimate the ingestion of radionuclides, based on the time-dependent concentrations of radiocesium in sewer sludge, which addresses the uncertainties of the two common methods. The newly proposed method, which we designate as SL, consists of three steps: (1) the separation of wet weather and dry weather data, (2) determining the mass balance of the wastewater treatment plant (WWTP), and (3) developing a reverse biokinetic model to relate the amount of radionuclides ingested to the amounts contained in the sewer sludge. We tested the new method using the time-dependent radiocesium concentrations in sewer sludge from the WWTP in Fukushima City. The results from the SL method agreed to those from the MB while overestimated those from DP method. The trend lines for all three methods, however, are in good agreement. Sensitivity analyses of SL method indicate further studies on uncertainties of sensitive parameters are deemed necessary to improve the accuracy of the method. PMID- 29597114 TI - Synthesis, in vitro alpha-glucosidase inhibitory potential and molecular docking study of thiadiazole analogs. AB - alpha-Glucosidase is a catabolic enzyme that regulates the body's plasma glucose levels by providing energy sources to maintain healthy functioning. 2-Amino thiadiazole (1-13) and 2-amino-thiadiazole based Schiff bases (14-22) were synthesized, characterized by 1H NMR and HREI-MS and screened for alpha glucosidase inhibitory activity. All twenty-two (22) analogs exhibit varied degree of alpha-glucosidase inhibitory potential with IC50 values ranging between 2.30 +/- 0.1 to 38.30 +/- 0.7 MUM, when compare with standard drug acarbose having IC50 value of 39.60 +/- 0.70 MUM. Among the series eight derivatives 1, 2, 6, 7, 14, 17, 19 and 20 showed outstanding alpha-glucosidase inhibitory potential with IC50 values of 3.30 +/- 0.1, 5.80 +/- 0.2, 2.30 +/- 0.1, 2.70 +/- 0.1, 2.30 +/- 0.1, 5.50 +/- 0.1, 4.70 +/- 0.2, and 5.50 +/- 0.2 MUM respectively, which is many fold better than the standard drug acarbose. The remaining analogs showed good to excellent alpha-glucosidase inhibition. Structure activity relationship has been established for all compounds. The binding interactions of these compounds were confirmed through molecular docking. PMID- 29597115 TI - Risk factors for musculoskeletal injury in elite pre-professional modern dancers: A prospective cohort prognostic study. AB - OBJECTIVES: To examine risk factors for injury in pre-professional modern dancers. DESIGN: With prospectively designed screening and injury surveillance, we evaluated four risk factors as categorical predictors of injury: i) hypermobility; ii) dance technique motor-control; iii) muscle tightness; iv) previous injury. Screening and injury data of 180 students enrolled in a university modern dance program were reviewed over 4-yrs of training. Dancers were divided into 3-groups based on predictor scores. Dance exposure was based on hours of technique classes/wk. Negative binomial log-linear analyses were conducted with the four predictors, p < 0.05. RESULTS: Dancers with low and high Beighton scores were 1.43 and 1.22 times more likely to sustain injury than dancers with mid-range scores (p <= 0.03). Dancers with better technique (low or medium scores) were 0.86 and 0.63 times less likely to sustain injury (p = 0.013 and p < 0.001) compared to those with poor technique. Dancers with one or 2-4 tight muscles were 2.7 and 4.0 times more likely to sustain injury (p <= 0.046). Dancers who sustained 2-4 injuries in the previous year were 1.38 times more likely to sustain subsequent injury (p < 0.001). CONCLUSIONS: This contributes new information on the value of preseason screening. Dancers with these risk factors may benefit from prevention programs. PMID- 29597116 TI - Elevated serum uric acid levels are associated with endothelial dysfunction in HIV patients receiving highly-active antiretroviral therapy. AB - BACKGROUND AND AIMS: Elevated serum uric acid (SUA) levels may be associated with endothelial dysfunction. Increased rates of metabolic syndrome (MS) and elevated SUA levels were described in human immunodeficiency virus (HIV) infected patients. We investigated whether SUA levels are associated with endothelial dysfunction in HIV positive patients receiving highly-active antiretroviral therapy (HAART) irrespective of MS. METHODS: In this cross-sectional study of 250 HIV positive patients receiving stable HAART, we evaluated the relationship between MS, SUA levels and endothelial function. SUA levels and brachial artery flow-mediated dilation (bFMD) were measured. The relationship between logarithmic (LG)-transformed SUA levels and bFMD was evaluated after correction for MS. RESULTS: MS was detected in 28.4% of patients and elevated SUA levels (>=6 mg/dL) in 25.2%. MS was associated with higher LG-SUA levels (age-, gender- and glomerular filtration rate-adjusted beta = 0.204, p = 0.001). The crude linear association between LG-SUA levels and LG-bFMD (beta = -0.166, p = 0.008) was abolished after correction for MS (beta = -0.089, p = 0.172). When SUA levels were used as a categorical variable (>=6 mg/dL or <6 mg/dL and SUA quartiles, respectively), the association between LG-SUA levels and LG-bFMD remained significant after adjustment for MS (beta = -0.142, p = 0.022 and beta = -0.163, p = 0.010, respectively). CONCLUSIONS: MS significantly affects SUA levels in HAART-treated HIV infected patients. The negative association between SUA and bFMD is independent of MS only for elevated SUA levels. PMID- 29597117 TI - Native and myeloperoxidase-oxidized low-density lipoproteins act in synergy to induce release of resolvin-D1 from endothelial cells. AB - BACKGROUND AND AIMS: Oxidation of native low-density lipoproteins (LDLs-nat) plays an important role in the development of atherosclerosis. A major player in LDL-nat oxidation is myeloperoxidase (MPO), a heme enzyme present in azurophil granules of neutrophils and monocytes. MPO produces oxidized LDLs called Mox LDLs, which cause a pro-inflammatory response in human microvascular endothelial cells (HMEC), monocyte/macrophage activation and formation of foam cells. Resolvin D1 (RvD1) is a compound derived from the metabolism of the polyunsaturated fatty acid DHA, which promotes resolution of inflammation at the ng/ml level. METHODS: In the present study, we used liquid chromatography-mass spectrometry (LC-MS/MS) to investigate the synthesis of RvD1 and its precursors - 17(S)-hydroxy docosahexaenoic acid (17S-HDHA) and docosahexaenoic acid (DHA) - by HMEC, in the presence of several concentrations of Mox-LDLs, copper-oxidized-LDLs (Ox-LDLs), and native LDLs or in mouse plasma. The LC-MS/MS method has been validated and applied to cell supernatants and plasma to measure production of RvD1 and its precursors in several conditions. RESULTS: Mox-LDLs played a significant role in the synthesis of RvD1 and 17S-HDHA from DHA compared to Ox LDLs. Moreover, Mox-LDLs and LDLs-nat acted in synergy to produce RvD1. In addition, different correlations were found between RvD1 and M1 macrophages, age of mice or Cl-Tyr/Tyr ratio. CONCLUSIONS: These results suggest that although Mox LDLs are known to be pro-inflammatory and deleterious in the context of atherosclerosis, they are also able to induce a pro-resolution effect by induction of RvD1 from HMEC. Finally, our data also suggest that HMEC can produce RvD1 on their own. PMID- 29597118 TI - Risk analysis of technological hazards: Simulation of scenarios and application of a local vulnerability index. AB - The potential impact of a technological accident can be assessed by risk estimation. Taking this into account, the latent or potential condition can be warned and mitigated. In this work we propose a methodology to estimate risk of technological hazards, focused on two components. The first one is the processing of meteorological databases to define the most probably and conservative scenario of study, and the second one, is the application of a local social vulnerability index to classify the population. In this case of study, the risk was estimated for a hypothetical release of liquefied ammonia in a meat-packing industry in the city of La Plata, Argentina. The method consists in integrating the simulated toxic threat zone with ALOHA software, and the layer of sociodemographic classification of the affected population. The results show the areas associated with higher risks of exposure to ammonia, which are worth being addressed for the prevention of disasters in the region. Advantageously, this systemic approach is methodologically flexible as it provides the possibility of being applied in various scenarios based on the available information of both, the exposed population and its meteorology. Furthermore, this methodology optimizes the processing of the input data and its calculation. PMID- 29597119 TI - Assessment of membrane photobioreactor (MPBR) performance parameters and operating conditions. AB - Membrane photobioreactor (MPBR) technology is an emerging algae-based wastewater treatment system. Given the limitations due to the general use of conventional analytical approaches in previous research, this study aims to provide a more comprehensive assessment of MPBR performance through advanced characterisation techniques. New performance parameters are also proposed, encompassing five important aspects of MPBR system efficiency (i.e. biomass concentration, composition, production, nutrient uptake and harvesting potential). Under initial standard operating conditions, performance parameters, such as cell count/MLSS ratio, cell viability, proportion of bacteria and biomass yield coefficient, were found to offer new insights into the operation of MPBR. These parameters were then used, for the first time, to systematically investigate MPBRs operated under different hydraulic retention times (HRTs) and solids retention times (SRTs). Applying shorter HRT and SRT was observed to increase cell viability and productivity (up to 0.25 * 107 cells/mL.d), as anticipated due to the higher nutrient loading. It was noted that the faster growing algal cells featured lower requirement for nutrients. On the other hand, extending HRT and SRT resulted in a more heterogeneous culture (lower cell count/MLSS ratio and higher proportion of bacteria), achieving a higher degree of autoflocculation and greater NO3-N and PO4-P removals of up to 79% and 78% respectively. The results demonstrate the trade-off between applying different HRTs and SRTs and the importance of fully characterising system performance to critically assess the advantages and limitations of chosen operating conditions. PMID- 29597120 TI - Highly effective enhancement of waste activated sludge dewaterability by altering proteins properties using methanol solution coupled with inorganic coagulants. AB - Proteins are the dominant organic component of extracellular polymeric substances (EPS) in waste activated sludge (WAS), and play an important role during sludge dewatering processes. Methanol is a polar hydrophilic reagent and can denature proteins, which suggested to us that the modification of protein configurations with methanol could improve sludge dewatering performance. In this study, methanol was used to precondition WAS prior to adding inorganic coagulants for dewatering enhancement. The morphology and EPS properties (especially of proteins) were investigated to analyze and explain the effects of methanol in the sludge conditioning process. The results show that methanol performed much better than traditional inorganic coagulants in improving sludge dewaterability in term of specific resistance to filtration (SRF) and cake solid content (CSC). Extractable proteins in EPS increased to a maximum when the concentration of methanol reached 40% (w/w) because cell membranes were destroyed and intracellular substances and water were released. Floc protein content was reduced with the further increase in methanol concentration due to protein precipitation. Confocal laser scanning microscopy analysis indicated that proteins precipitated and formed larger aggregates because methanol destroyed both the hydration shell and the hydrophobic clusters of proteins and expanded the protein tertiary structure to release interstitial water and bound water. The combination treatment of methanol and inorganic coagulants (PAC or FeCl3) showed significant synergetic effects on enhancing sludge dewatering and cake drying. In practical applications, methanol from the dewatering sludge can be returned to the biochemical pool and used as the carbon source for nitrogen removal in the denitrification process. This integrated process is appropriate for sludge final disposal technologies that have high energy demands, such as incineration and pyrolysis. This paper describes a novel approach to improving sludge dewaterability through the alteration of protein properties by use of physiochemical techniques. PMID- 29597121 TI - Short term protein supplementation during a long interval prostaglandin-based protocol for timed AI in sheep. AB - The aim of this study was to evaluate the reproductive impact of a short-term protein supplementation on a long interval prostaglandin-based protocol (two PG injections 15 d apart; PG15) for timed artificial insemination in sheep. During the breeding season, 437 multiparous Merino ewes grazing native pastures (forage allowance of 6 kg of dry matter/100 kg of live weight; crude protein: 10.8%, metabolic energy: 2.1 Mcal/kg of dry matter) were selected. Ewes were allocated, according to body condition score (3.2 +/- 0.2) and body weight (40.6 +/- 4.9 kg, mean +/- SD), to a 2 * 2 factorial design: type of estrus -spontaneous estrus (SE) or induced with PG15 (PG15)-, and supplementation (yes or no) before insemination (+FF; soybean meal at Days -10 to -3; crude protein: 51.9%, metabolic energy: 2.8 Mcal/kg of dry matter; average consumption 0.9% live weight/ewe/day of dry matter). All ewes were cervically artificial inseminated (Day -2 to -3 in SE ewes at estrus detection; Day 0 = timed artificial insemination in PG15 ewes). Ovulation rate on Day 7, non-return to service on Day 23, conception, fertility, prolificacy and fecundity on Day 60 were evaluated. Ovulation rate (1.17 +/- 0.40 vs. 1.06 +/- 0.25), non-return to service at Day 23 (81.7 vs. 64.2%), conception (78.8 vs. 61.5%), fertility (75.2 vs. 61.5%) and fecundity (0.77 vs. 0.62) were higher in ewes from SE than PG15 group (P < 0.05). However, no differences were observed in prolificacy (1.02 +/- 0.16 vs. 1.01 +/- 0,12) between groups (P > 0.05). Protein supplementation increased ovulation rate (1.30 +/- 0.45 vs. 1.17 +/- 0.40), prolificacy (1.18 +/- 0.39 vs. 1.02 +/- 0.16) and fecundity (0.94 vs. 0.77%; P < 0.05), but not non-return to service on Day 23 (83.8 vs. 81.7%), conception (82.9 vs. 78.8%) or fertility (79.1 vs. 75.2%; P > 0.05) in SE group. The supplement feed to PG15 ewes increased ovulation rate (1.35 +/- 0.45 vs. 1.06 +/- 0.25), prolificacy (1.25 +/- 0.43 vs. 1.01 +/- 0.12) and fecundity (0.79 vs. 0.62%; P < 0.05) to levels comparable to SE + FF ewes (P > 0.05). The magnitude of the increase in ovulation rate in PG15 was greater than in the SE group (27 vs. 11%; P < 0.05). However, non-return to service on Day 23 (65.1 vs. 64.2%), conception (63.3 vs 61.5%), and fertility rate (63.3 vs. 61.5%; P < 0.05) remained similar in PG15 supplemented or not supplemented ewes. In conclusion, a short-term protein supplementation before cervical time artificial insemination improved the reproductive performance of ewes synchronized with the PG15 protocol to levels comparable to the SE group. PMID- 29597122 TI - In vitro sperm quality and DNA integrity of SexedULTRATM sex-sorted sperm compared to non-sorted bovine sperm. AB - SexedULTRATM is an improved method of sex-sorting sperm creating a less damaging environment to retain sperm integrity through the sorting process. The aim of this study was to evaluate the in vitro characteristics of fresh and frozen bovine sperm using the SexedULTRATM method, and compare it to conventional (non sorted) sperm. For both methods, percent total sperm motility was estimated visually and also classified into total and progressively motile using a computer assisted sperm analyzer (CASA). Percent sperm with intact plasma membranes (VIA) and acrosomes (PIA) were assessed using flow cytometry and sperm DNA fragmentation index (DFI) was estimated using the Bull sperm Halomax(r) Kit. Two contemporaneous ejaculates from 10 bulls were processed and cryopreserved using one of the two procedures (SexedULTRATM and conventional). Sperm motility, VIA and PIA were assessed post-thaw (0 h) and post-incubation (3 h at 37 degrees C, 8 h and 24 h at 18 degrees C). DFI was analyzed post-thaw (0 h) and after 6, 24, 48 and 72 h of incubation at 37 degrees C. In a second experiment, ejaculates from 7 bulls were split sampled into the two types of processing (SexedULTRATM and conventional) and diluted using a fresh semen extender developed for sex sorted bovine sperm. Sperm quality was assessed after dilution (0 h) and after incubation for 12, 24, 48, 72 h at 18 degrees , and the same time points of incubation at 37 degrees C for DFI. Frozen-thawed SexedULTRATM sperm was significantly (P < 0.05) better than conventional semen after a 3 h incubation at 37 degrees C for PIA, and after a 24 h incubation at 18 degrees C for percent visual motility and PIA. DFI was significantly lower for SexedULTRATM compared to conventional at all time points of incubation (37 degrees C). Fresh SexedULTRATM sperm showed improved quality compared to conventional at all time points of incubation at 18 degrees C for percent visual and total motile sperm, VIA, PIA, and DFI. Significant differences were also found in progressive motile sperm immediately after dilution (0 h), but not at any time point after incubation. The results show that the SexedULTRATM process maintains the quality of sex-sorted sperm and, in many cases, has better in vitro longevity than conventional semen. PMID- 29597123 TI - Systemic profiling of ectopic fat deposits in the reproductive tract of dairy cows. AB - During the transition period, high-yielding dairy cows suffer from negative energy balance, intense lipomobilization and impaired lipid metabolism; this metabolic condition can lead to overburdened triglycerides accumulation in the liver, known as liver lipidosis, which has been associated to impaired fertility in dairy cows. The mechanisms of this impairment can be in principle correlated with the presence and the extent of ectopic fat depots. However, current methods for evaluating fat accumulation in liver and in the reproductive tract suffer from low resolution, sensitivity, and specificity. Confocal microscopes are equipped with Gallium arsenide phosphide detectors, thus enabling the acquisition of intense signals from tissue biopsies. This method could differentiate whether fat deposition occurred without requiring sample sectioning. Here, we examined with this technique liver, uterine and ovarian samples of heifers and regularly slaughtered repeat breeder and overconditioned dairy cows, to quantify lipid droplets and depots at a submicrometer scale with high specificity. With the aid of this technique, we found lipid depots in uterine and ovarian specimens. Moreover, we found that the size and number of depots increased with the degree of liver lipidosis. Further studies are needed to elucidate the relationship between the severity and extent of these deposits and the fertility of lactating dairy cows. Since tissues other than liver display different characteristic lipid droplet distributions, this technique can be potentially employed to shed new light on the pathogenesis of lipidosis and to assess new risk factors for infertility. PMID- 29597124 TI - Plasma IGF-I, INSL3, testosterone, inhibin concentrations and scrotal circumferences surrounding puberty in Japanese Black beef bulls with normal and abnormal semen. AB - The relationships between semen abnormalities and peripheral concentrations of testicular and metabolic hormones in beef bulls are unclear. Here we compared plasma insulin-like growth factor I (IGF-I), insulin-like peptide 3 (INSL3), testosterone, inhibin concentrations, and scrotal circumferences surrounding puberty in Japanese Black beef bulls (n = 66) with normal or abnormal semen. We collected blood samples and measured scrotal circumferences monthly from 4 to 24 months of age. Semen was collected weekly from 12 months until at least 18 months of age. Fresh semen was evaluated for semen volume, sperm motility, concentrations, and morphological defects. The normal fresh semen was frozen by a standard method and examined for post-thaw sperm motility and fertility. Bulls were classified as having either normal post-thaw semen (n = 45) or abnormal semen (n = 21, when at least one of the above test items was abnormal for 6 months). Abnormal semen was classified into abnormal fresh or low-fertility post thaw which evaluated for rates of transferable embryos. The abnormal fresh was categorized as having sperm morphological defects, low motility, and morphological defects plus low motility. Scrotal circumferences were smaller for the abnormal-semen group vs. the normal-semen group at 20 and 24 months (p < 0.05). Plasma IGF-I, INSL3, and inhibin concentrations in the abnormal-semen group were lower than those of the normal-semen group (p < 0.05) surrounding puberty (4-6, 8, 18-22, and 24 months for IGF-I; 6, 9, 11-14, 17, and 20-21 months for INSL3; 5, 8-13, 16, 17, 19, and 20 months for inhibin). The plasma testosterone concentrations were lower in the abnormal-semen bulls vs. normal semen bulls only at 22 months (p < 0.05). Analyses of the classified abnormal semen showed lower plasma INSL3 concentrations for morphological defects plus low motility in fresh semen (p < 0.05) and lower IGF-I and inhibin concentrations for low-fertility post-thaw semen (p < 0.05) compared to the normal semen. Our results suggest that reduced secretions of IGF-I, INSL3, and inhibin surrounding puberty may be associated with semen aberration in beef bulls. Notably, the combined sperm abnormality of morphological defects and low motility in fresh semen could involve lowered INSL3, whereas the low-fertility post-thaw semen might be related to decreases of IGF-I and/or inhibin. Pre-puberty blood IGF-I, INSL3 and inhibin concentrations could be used as indicators to predict aberrant semen in beef bulls. PMID- 29597125 TI - The anti-inflammatory effect of exogenous lactoferrin on breeding-induced endometritis when administered post-breeding in susceptible mares. AB - The deposition of semen into the uterus of the horse induces a transient innate immune response that lasts 24-36 h in the normal mare. There exists a subset of mares that are unable to resolve this inflammation in a timely manner, and are classified as susceptible to the disease of persistent breeding-induced endometritis (PBIE). Lactoferrin is a protein of interest as a potential therapeutic for this persistent inflammation due to its anti-inflammatory and bactericidal properties. The addition of human recombinant lactoferrin (hrLF) to the insemination dose was previously shown to suppress mRNA expression of the pro inflammatory cytokine tumor necrosis factor (TNF)-alpha at 6 h after insemination, but no studies have shown the effect of lactoferrin when infused post-breeding. Therefore, the objectives of this study were to (1) assess the safety of intra-uterine infusion of hrLF, (2) evaluate the effect of intrauterine infusion of hrLF post-breeding as a modulator of the immune response to breeding in the susceptible mare, and (3) determine the most effective concentration of hrLF. For the first experiment four normal mares received an intrauterine infusion of 500 MUg/mL hrLF resuspended in 10 mL lactated Ringer's solution (LRS) and heart rate, rectal temperature, respiration, and endometrial quality were evaluated. For the second experiment, six mares classified as susceptible to PBIE were bred during estrus with 500 * 106 progressively motile sperm comprised of the ejaculates from two stallions, which were centrifuged over Androcoll-E to remove seminal plasma. Each insemination dose was resuspended in 30 mL LRS. Six hours after breeding, a 1L LRS uterine lavage was performed prior to treatments. Four treatments were administered over four consecutive estrous cycles in randomized order of: 10 mL LRS (vehicle control), 50 MUg/mL hrLF resuspended in 10 mL LRS, 250 MUg/mL hrLF resuspended in 10 mL LRS, and 500 MUg/mL hrLF resuspended in 10 mL LRS. Twenty-four hours after breeding the mares were evaluated via transrectal ultrasonography for fluid retention. A low volume uterine lavage (250 mL LRS) was performed and the effluent was evaluated for polymorphonuclear neutrophils (PMNs). Finally, an endometrial biopsy was obtained for qPCR analysis of selected inflammatory cytokines. Lactoferrin had no significant overall effect on vital signs or endometrial quality. The addition of hrLF (50 MUg/mL, 250 MUg/mL, 500 MUg/mL) did not significantly affect the amount of fluid detected post-breeding, but suppressed the ratio of PMNs to epithelial cells at all three concentrations compared to controls. In addition, all three concentrations of hrLF increased the mRNA expression of the anti-inflammatory cytokine interleukin-1 receptor antagonist (IL-1RN), while the 50 MUg/mL dose significantly suppressed mRNA expression of the pro-inflammatory cytokine interferon gamma (IFNgamma). In conclusion, the infusion of hrLF post-breeding was found to modulate the inflammatory response to breeding in the mare, and appears to be most effective at the 50 MUg/mL concentration. PMID- 29597126 TI - Preparation of polymeric Janus microparticles with hierarchically porous structure and enhanced anisotropy. AB - Anisotropic Janus particles are of great interest for many applications. It is well known that behavior and utility of Janus particles are highly dependent on their chemistry and geometry. Herein, we report the synthesis of monodisperse polymeric Janus microparticles that were anisotropic not only in chemistry and shape but also in surface morphology and porosity, via a modified seeded polymerization technique. Chemical composition, shape, morphology and porosity of the polymeric Janus microparticles were flexibly controlled by utilizing different quantities and species of monomer and porogen. The polymeric Janus microparticles exhibited hierarchically porous structure, including micro- and meso-pores as evidenced by isothermal nitrogen adsorption and desorption. Due to the high specific surface area, anisotropy of the polymeric Janus microparticles was enhanced according to the greater fluorescence contrast on distinct sides of the polymeric Janus microparticles. Moreover, swelling and phase-separation processes of cross-linked seeds were in situ observed on an optical microscope to demonstrate the formation mechanism of the polymeric Janus microparticles. PMID- 29597127 TI - Viscoelastic diamine surfactant for stable carbon dioxide/water foams over a wide range in salinity and temperature. AB - HYPOTHESIS: The viscosity and stability of CO2/water foams at elevated temperature can be increased significantly with highly viscoelastic aqueous lamellae. The slow thinning of these viscoelastic lamellae leads to greater foam stability upon slowing down Ostwald ripening and coalescence. In the aqueous phase, the viscoelasticity may be increased by increasing the surfactant tail length to form more entangled micelles even at high temperatures and salinity. EXPERIMENTS: Systematic measurements of the steady state shear viscosity of aqueous solutions of the diamine surfactant (C16-18N(CH3)C3N(CH3)2) were conducted at varying surfactant concentrations and salinity to determine the parameters for formation of entangled wormlike micelles. The apparent viscosity and stability of CO2/water foams were compared for systems with viscoelastic entangled micellar aqueous phases relative to those with much less viscous spherical micelles. FINDINGS: We demonstrated for the first time stable CO2/water foams at temperatures up to 120 degrees C and CO2 volumetric fractions up to 0.98 with a single diamine surfactant, C16-18N(CH3)C3N(CH3)2. The foam stability was increased by increasing the packing parameter of the surfactant with a long tail and methyl substitution on the amine to form entangled viscoelastic wormlike micelles in the aqueous phase. The foam was more viscous and stable compared to foams with spherical micelles in the aqueous lamellae as seen with C12-14N(EO)2 and C16-18N(EO)C3N(EO)2.

AB - Heterozygous non-synonymous (p.S142F) mutation in HNF1A leads to maturity-onset diabetes of the young (MODY) type 3, which is a subtype of dominant inherited young-onset non-autoimmune diabetes due to the defect of insulin secretion from pancreatic beta cells. We generated induced pluripotent stem cells (iPSCs) from a patient with HNF1A p.S142F mutation. Cells from this patient, which were reprogrammed by non-integrative viral transduction had normal karyotype, harboured the HNF1A p.S142F mutation, expressed pluripotency hallmarks. PMID- 29597129 TI - The effects of plasma gelsolin on human erythroblast maturation for erythrocyte production. AB - Gelsolin is an actin binding protein present in blood plasma and in cytoplasm of cells including macrophages. Gelsolin has important functions in cell cycle regulation, apoptotic regulation, and morphogenesis. Even though bone marrow macrophages and serum factors are critical for regulating erythropoiesis, the role of gelsolin on human erythroblasts has not been studied. Here, we investigated the effects of human recombinant plasma gelsolin (pGSN) on human immature erythroblasts. CD34+ cells isolated from cord blood were differentiated into erythroid cells in serum-free medium. When pGSN was applied to the culture medium, it accelerated basophilic and polychromatic erythroblast maturation and increased the enucleation rate with highly expressed erythropoiesis-related mRNAs. Also, pGSN was effective in reducing dysplastic changes caused by vincristine, suggesting its role in cell cycle progression at G2/M checkpoints. Also, pGSN activated caspase-3 during maturation stages in which caspase-3 functions as a non-apoptotic maturational signal or a pro-apoptotic signal depending on maturation stages. Our results suggest that pGSN has a pivotal role in maturation of erythroblasts and this factor might be one of the way how bone marrow macrophages and previously unknown serum factors work to control erythropoiesis. pGSN might be used as additive for in vitro production of erythrocytes. PMID- 29597130 TI - MicroRNA co-expression patterns unravel the relevance of extra cellular matrix and immunity in breast cancer. AB - BACKGROUND: Aberrant microRNA (miRNA) expression is associated with human tumors, including breast cancer (BC), and has diagnostic and therapeutic potential. BC tissue is characterized by distinctive miRNA signatures associated with cancer development or progression. METHODS: We explored miRNA profiles from BC tissues by unsupervised hierarchical clustering. Functional analysis was based on miRNA mRNA data integration and Gene Set Enrichment Analysis. RESULTS: Partition of miRNA expression data from BC samples of Chinese Han and Caucasian subjects identified clusters of correlated miRNAs that were subjected to a global and integrative analysis aimed at identifying novel associations with biological and clinical value. Co-expression of miRNAs clustered in the same module was partially explained by co-transcription of the same genomic locus or involvement in similar biological functions. No significant associations were found among miRNA clusters and clinical-pathological variables, except for ER status and immune infiltration estimated by CIBERSORT. A large number of miRNA clusters, instead, were significantly differentially expressed in PAM 50 and extracellular matrix (ECM) subgroups. Specifically, a new cluster including several relatively new miRNAs was overexpressed in ECM3 tumors, characterized by increased epithelial to mesenchymal transition (EMT). An integrative approach to extract meaningful relationships on miRNA/mRNA networks and predict the functional role of the miRNA clusters indicates that immune system, ECM, proliferation, transcription and DNA repair were the biological functions more targeted by miRNAs aberrantly expressed in BC. CONCLUSIONS: We then identified novel miRNA patterns associated with BC molecular features, and described a complex regulatory network where miRNAs belonging to the same module cooperate in finely tuning gene expression.

AB - Trolling mode atomic force microscopy (TR-AFM) has overcome many imaging problems in liquid environments by considerably reducing the liquid-resonator interaction forces. The finite element model of the TR-AFM resonator considering the effects of fluid and nanoneedle flexibility is presented in this research, for the first time. The model is verified by ABAQUS software. The effect of installation angle of the microbeam relative to the horizon and the effect of fluid on the system behavior are investigated. Using the finite element model, frequency response curve of the system is obtained and validated around the frequency of the operating mode by the available experimental results, in air and liquid. The changes in the natural frequencies in the presence of liquid are studied. The effects of tip-sample interaction on the excitation of higher order modes of the system are also investigated in air and liquid environments. PMID- 29597131 TI - Health-related quality of life and utility scores of patients with breast neoplasms in China: A multicenter cross-sectional survey. AB - BACKGROUND: Health-related quality of life and utility scores of patients with breast cancer and precancerous lesions are sparse in China. This study aimed to derive utility scores of patients with breast cancer and precancer in China. MATERIAL AND METHODS: An interviewer-administered cross-sectional survey was conducted in 12 provinces across China from 2013 to 2014. The three-level EuroQol 5-Dimension instrument was used to evaluate quality of life, and utility scores were generated using the Chinese value set. Univariate and multivariate analyses were performed to explore the determinants of utility scores. RESULTS: In total, 2626 breast cancer and 471 precancer patients were included. Mean age was 49.1 for breast cancer and 41.4 years for precancer (p < 0.001). Among the five dimensions, pain/discomfort was the most reported problem, 53.9% in breast cancer and 29.3% in precancer patients. Mean (95% CI) utility scores for breast cancer and precancer patients were estimated as 0.887 (0.875-0.899) and 0.781 (0.774 0.788), and the scores of breast cancer at stage-I, stage-II, stage-III and stage IV were 0.789 (0.774-0.805), 0.793 (0.783-0.802), 0.774 (0.759-0.788) and 0.686 (0.654-0.717), respectively. Mean (95% CI) visual analogue scale scores for breast cancer and precancer were 75.6 (74.0-77.3) and 72.8 (72.3-73.3). Multiple regression showed advanced clinical stage, lower educational level, lower household income, surgery treatment, and undergoing treatment were independently associated with lower utility scores for breast cancer patients. CONCLUSION: The utility scores deteriorate with the severity of breast neoplasms. Detailed utility scores of breast cancer and precancer are fundamental for further cost utility analysis in China. PMID- 29597133 TI - Changes in the prevalence of comorbidity in the Australian population with cancer, 2007-2014. AB - BACKGROUND: Coexistence of multiple chronic diseases is highly prevalent among the cancer population. This study aims to assess changes in the prevalence of chronic conditions among the population with cancer compared to the Australian general population between 2007 and 2014. METHODS: Data from three successive National Health Surveys conducted by the Australian Bureau of Statistics between 2007 and 2014 were utilized. Comparisons were made between the samples of the Australian population aged 25 years and above with a history of cancer and those respondents who did not report having had a cancer using logistics regression models. RESULTS: People with a history of cancer had significantly higher odds of reporting non-infectious comorbidity compared to the non-cancer groups across the three surveys. There were no significant changes in the prevalence of diseases affecting circulatory, musculoskeletal, digestive, nervous system, blood and blood forming organs, eye, skin and infectious and parasitic diseases over time among the population with cancer. The prevalence of mental and behavioural problems, endocrine, nutritional and metabolic diseases, and diseases of respiratory and genitourinary system has increased over time among the cancer survivors. CONCLUSION: Comorbidity is more prevalent among the cancer population than the general population without cancer. The prevalence of comorbidity was fairly stable for most but not all comorbidities in the population with cancer over the eight-year study period. Further studies on the impacts of coordinated care models for the management of multi-morbidity experienced by cancer survivors that align with the 'National Strategic Framework for Chronic Conditions' are needed.

AB - Recent studies have shown that Connexin43 mimetic peptide (Cx43 MP) can prevent secondary damage following retinal ischaemic and inflammatory disorders by blocking uncontrolled Cx43 hemichannel opening. However, limitations in peptide stability and the presence of various intraocular barriers limit efficient retinal delivery in the clinical setting. The present study aimed to achieve targeted and sustained peptide delivery to the retina by encapsulating Cx43 MP into hyaluronic acid (HA) coated albumin nanoparticles (NPs). Intraocular biodistribution, particle retention, retinal targeting, and therapeutic efficacy of intravitreally injected NPs encapsulating Cx43 MP were evaluated in a rat model of retinal ischaemia-reperfusion injury. NPs rapidly diffused through the vitreous and specifically targeted CD44-expressing retinal cells. NPs remained at the target site for extended periods enabling sustained peptide release and thus prolonged therapeutic action. Compared to free Cx43 MP, Cx43 MP loaded NPs enabled enhanced therapeutic efficacy preventing thinning of retinal layers and disruption of retinal blood vessels. Immunohistochemical results confirm that Cx43 MP loaded NPs efficiently reduced Cx43 expression, thereby suppressing ongoing inflammation and preventing the loss of retinal ganglion cells. Overall, HA coated NPs could have great potential as a peptide delivery platform in the treatment of chronic retinal degenerative and inflammatory disorders. PMID- 29597135 TI - Direct matching methods for coils and preamplifiers in MRI. AB - In this paper, direct matching methods for coils and preamplifiers in receiver arrays are presented. Instead of compensating the reactance of the input impedance of preamplifiers, in our method, the reactance was used to resonate with the coil matching networks and thus to decouple the coils. Furthermore, coil matching networks and preamplifier input matching networks were combined, meaning the coil loop can be matched to the transistor in the preamplifier directly. These matching methods and, for comparison, the conventional matching method were implemented with custom-made preamplifiers and coils. Decoupling and noise matching performance were compared between these three configurations. Phase shifting networks between coils and preamplifiers are not necessary in our matching methods. With fewer components, these matching networks showed lower noise factors, while similar preamplifier-decoupling performance was found for all three methods. PMID- 29597136 TI - Intolerance for smoking abstinence among nicotine-deprived, treatment-seeking smokers. AB - INTRODUCTION: The Intolerance for Smoking Abstinence Discomfort Questionnaire (IDQ-S) assesses distress tolerance specific to nicotine withdrawal. Though developed to assess withdrawal-related distress, the IDQ-S has not been validated among nicotine-deprived, treatment-seeking smokers. The present study extended previous research by examining the predictive utility of the IDQ-S among abstinent, motivated-to-quit smokers. METHODS: Abstinent, treatment-seeking smokers completed the IDQ-S Withdrawal Intolerance and Lack of Cognitive Coping scales, assessments of nicotine dependence and reinforcement, and smoking history at baseline. At baseline and at 24-h, 2-week, and 1-month follow-up, participants completed a smoking cue-reactivity task (collection of cue-elicited craving and negative affect), and assessments of cigarettes per day (CPD; daily diaries at follow-up), carbon monoxide (CO), and cotinine. RESULTS: Greater IDQ-S Withdrawal Intolerance was associated with younger age, higher nicotine dependence and reinforcement, and less smoking years (ps < .03). Greater IDQ-S Lack of Cognitive Coping was associated with less education, lower nicotine dependence and reinforcement, higher baseline CPD, and no prior quit attempts (ps < .04). IDQ-S scales did not significantly predict cue-elicited craving or negative affect, CPD, CO, or cotinine levels at follow-up (ps > .10). CONCLUSIONS: Withdrawal intolerance and lack of cognitive coping did not predict smoking outcomes among nicotine-deprived, treatment-seeking smokers, but were associated with smoking characteristics, including nicotine dependence and reinforcement. Withdrawal intolerance and lack of cognitive coping may not be especially useful in predicting craving and smoking behavior, but future studies should replicate the present study's findings and assess the stability of the IDQ-S before forming firm conclusions about its predictive utility. PMID- 29597137 TI - Antibacterial activity of acidified sodium benzoate against Escherichia coli O157:H7, Salmonella enterica, and Listeria monocytogenes in tryptic soy broth and on cherry tomatoes. AB - Concerns about undesirable by-products from chlorine sanitation of fresh produce and the limited efficacy with the presence of organic matter, have led to studies on alternative washing solutions. The aim of this study was to evaluate the antibacterial activities of acidified sodium benzoate (NaB) solutions against Escherichia coli O157:H7, Salmonella enterica and Listeria monocytogenes in growth medium and on cherry tomatoes. Experimentally, the minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs, >3 Log reduction) of NaB against E. coli O157:H7 ATCC 43895, S. Enteritidis, and L. monocytogenes Scott A were determined at pH 7.0-4.0 using micro-broth dilution method and agar plating method, respectively. The reduction of the three bacteria in tryptic soy broth (TSB) by 500 and 1000 ppm NaB at pH 2.0, 2.5 and 3.0 for 30 min at 21 degrees C was compared. Residual bacterial cocktails inoculated on cherry tomatoes were determined after soaking in 3000 ppm NaB solution adjusted to pH 2.0 for 3 min at 21 degrees C. Results showed that the MBC of NaB reduced from >10,000 ppm at pH 7.0 to 1000 ppm at pH 4.0 and was identical for the three bacteria. The log reduction of bacteria in TSB indicated that 1000 ppm NaB at pH 2.0 was the most effective in killing the three pathogens. The respective reduction of E. coli O157:H7 and S. enterica cocktails inoculated on cherry tomatoes immersed in 3000 ppm NaB (pH 2.0) at 21 degrees C for 3 min was 4.99 +/ 0.57 and 4.08 +/- 0.65 log CFU/g, which was significantly higher (p < 0.05) than the treatments of 200 ppm free chlorine at pH 6.5. Conversely, the reduction of L. monocytogenes on tomatoes by 3000 ppm NaB (4.88 +/- 0.73 log CFU/g) was similar (p > 0.05) to 200 ppm chlorine. Furthermore, the reduction of bacterial cocktails on tomatoes by 3000 ppm NaB at pH 2.0 was not affected after adding 1% tomato puree, and bacteria were not detected in NaB washing solutions with and without 1% tomato puree and on following un-inoculated tomatoes. This study showed that acidified NaB solution may be used as an alternative post-harvest wash of produce. PMID- 29597138 TI - Rapid eye movement sleep behavior disorder or epileptic seizure during sleep? A video analysis of motor events. AB - PURPOSE: To compare the motor semiology of sleep behavior disorder (RBD) during rapid eye movement (REM) with epileptic seizures in non-REM and REM sleep. METHODS: We analyzed the types and frequency of motor events from videos of patients with RBD (n = 15, mean age 64.8 years, 179 motor episodes) and patients with epilepsy (n = 15, mean age 34.4 years, 87 sleep-related epileptic seizures including 34 during REM sleep). RESULTS: Patients with sleep-related epileptic seizures more often woke up abruptly (28% vs. 0.3%), raised head/trunk (31% vs. 1.6%), opened their eyes (89% vs. 5%), had whole body movements (74% vs. 14%) or dystonic posturing (29% vs. 1.3%), manipulated objects in their environment (44% vs. 3.9%), as if emerging from sleep with ictal automatisms, and sniffed, coughed, or breathed differently during motor events. In contrast, RBD patients more often remained lying down with closed eyes (99% vs. 78%) as if still asleep, with non-stereotyped jerky movements (42% vs. 8%) and outward-directed behaviors (14% vs. 2%) than patients with epilepsy. There were no differences in violent behaviors and vocalizations between groups. Comparison with subgroups of REM or non-REM sleep seizures yielded many similar findings. CONCLUSION: These different motor patterns discriminate between RBD events and sleep-associated seizures, and could be used as an aid to differential diagnosis. PMID- 29597139 TI - Microbial effectors and the role of water and sugar in the infection battle ground. AB - Phytopathogenic microbes multiply in the apoplast-a plant's intercellular spaces of infected plants, and hence their success relies on the conditions in this habitat. Despite being extracellular parasites, most microbes translocate effectors into host cells that promote disease by acting inside cells. Initial studies suggested that effectors act predominantly as suppressors of plant immunity. These pioneering studies were trend-setting, causing a strong bias in the functional investigation of effectors. Yet, recent studies on bacterial model pathogens have identified effectors that promote disease by causing either increased sugar or water levels in the apoplast. These studies are likely to initiate a new era of effector research that will clarify the disease-promoting rather than defense-suppressing function of effectors, a molecular rather than genetic distinction. PMID- 29597141 TI - Preliminary evaluation of 18F-labeled LLP2A-trifluoroborate conjugates as VLA-4 (alpha4beta1 integrin) specific radiotracers for PET imaging of melanoma. AB - INTRODUCTION: The transmembrane alpha4beta1 integrin receptor, or very-late antigen 4 (VLA-4), is associated with tumor metastasis and angiogenesis, the development of chemotherapeutic drug resistance, and is overexpressed in multiple myelomas, osteosarcomas, lymphomas, leukemias, and melanomas. The peptidomimetic, LLP2A, is a high-affinity ligand with specificity for the extracellular portion of VLA-4 and several conjugates have been evaluated in vivo by NIR-fluorescence, 111In-SPECT and 68Ga- and 64Cu-PET imaging, but to date, not with 18F-PET. METHODS: Using two highly stable organotrifluoroborate prosthetic groups: ammoniumdimethyl-trifluoroborate (AMBF3) and a new N-pyridinyl-para trifluoroborate (N-Pyr-p-BF3), both capable of facile aqueous 18F-labeling by isotope exchange (IEX), we present the first PET imaging evaluations of two [18F]R-BF3--PEG2-LLP2A tracers using VLA-4 overexpressing B16-F10 murine melanoma tumor mouse models. RESULTS: Here, we demonstrate successful one-step 18F labeling of both conjugates with wet NCA [18F]F- in radiochemical yields of up to 11.6% within 75 min at molar activities of 40-100 GBq/MUmol. Average tumor uptake values based on ex vivo biodistribution values were 4.4%ID/g (11) and 2.8%ID/g (12) using 18F-labeled LLP2A-conjugates with the two prosthetic groups: N-Pyr-p BF3 (5) and alkyl-N,N-dimethylammonio-BF3 (AMBF3) (7), respectively, and was found to be target-specific as evidenced by in vivo blocking controls. Dynamic PET scanning and biodistribution studies revealed slow clearance of the [18F]R BF3--PEG2-LLP2A tracers from the tumors, and also substantial uptake in the intestines, gall bladder, liver and bladder. Observed bone uptake was blockable, consistent with known VLA-4 expression in hematopoietic stem cells found in bone marrow. CONCLUSIONS: These studies show that these [18F]R-BF3--PEG2-LLP2A conjugates (11 and 12) are promising VLA-4 targeting radiotracers, yet, further optimization will be required to reduce uptake in the gastro-intestinal tract. PMID- 29597142 TI - Programmable prostate palpation simulator using property-changing pneumatic bladder. AB - The currently available prostate palpation simulators are based on either a physical mock-up or pure virtual simulation. Both cases have their inherent limitations. The former lacks flexibility in presenting abnormalities and scenarios because of the static nature of the mock-up and has usability issues because the prostate model must be replaced in different scenarios. The latter has realism issues, particularly in haptic feedback, because of the very limited performance of haptic hardware and inaccurate haptic simulation. This paper presents a highly flexible and programmable simulator with high haptic fidelity. Our new approach is based on a pneumatic-driven, property-changing, silicone prostate mock-up that can be embedded in a human torso mannequin. The mock-up has seven pneumatically controlled, multi-layered bladder cells to mimic the stiffness, size, and location changes of nodules in the prostate. The size is controlled by inflating the bladder with positive pressure in the chamber, and a hard nodule can be generated using the particle jamming technique; the fine sand in the bladder becomes stiff when it is vacuumed. The programmable valves and system identification process enable us to precisely control the size and stiffness, which results in a simulator that can realistically generate many different diseases without replacing anything. The three most common abnormalities in a prostate are selected for demonstration, and multiple progressive stages of each abnormality are carefully designed based on medical data. A human perception experiment is performed by actual medical professionals and confirms that our simulator exhibits higher realism and usability than do the conventional simulators. PMID- 29597140 TI - Presynaptic origins of distinct modes of neurotransmitter release. AB - Presynaptic nerve terminals release neurotransmitter synchronously, asynchronously or spontaneously. During synchronous neurotransmission release is precisely coupled to action potentials, in contrast, asynchronous release events show only loose temporal coupling to presynaptic activity whereas spontaneous neurotransmission occurs independent of presynaptic activity. The mechanisms that give rise to this diversity in neurotransmitter release modes are poorly understood. Recent studies have described several presynaptic molecular pathways controlling synaptic vesicle pool segregation and recycling, which in turn may dictate distinct modes of neurotransmitter release. In this article, we review this recent work regarding neurotransmitter release modes and their relationship to synaptic vesicle pool dynamics as well as the molecular machinery that establishes synaptic vesicle pool identity. PMID- 29597143 TI - A hierarchical pipeline for breast boundary segmentation and calcification detection in mammograms. AB - Breast cancer is one of the most common cancer risks to women in the world. Amongst multiple breast imaging modalities, mammography has been widely used in breast cancer diagnosis and screening. Quantitative analyses including breast boundary segmentation and calcification localization are essential steps in a Computer Aided Diagnosis system based on mammography analysis. Due to uneven signal spatial distributions of pectoral muscle and glandular tissue, plus various artifacts in imaging, it is still challenging to automatically analyze mammogram images with high precision. In this paper, a fully automated pipeline of mammogram image processing is proposed, which estimates skin-air boundary using gradient weight map, detects pectoral-breast boundary by unsupervised pixel wise labeling with no pre-labeled areas needed, and finally detects calcifications inside the breast region with a novel texture filter. Experimental results on Mammogram Image Analysis Society database show that the proposed method performs breast boundary segmentation and calcification detection with high accuracy of 97.08% and 96.15% respectively, and slightly higher accuracies are achieved on Full-Field Digital Mammography image datasets. Calculation of Jaccard and Dice indexes between segmented breast regions and the ground truths are also included as comprehensive similarity evaluations, which could provide valuable support for mammogram analysis in clinic. PMID- 29597146 TI - Electromyography comparison of the effects of various footwear in the activity patterns of the peroneus longus and brevis muscles. AB - BACKGROUND: Peroneus longus and brevis (PLB) disorders are commonly in people with lateral ligamentous instability, ankle pain, lateral hindfoot pain and structures of the proximal compartment of the lower legs and their muscle activity is believed to be influenced by different footwear types. The proposal of this research is to evaluate the effects of five types of footwear with respect to the barefoot condition and analyze the activity patterns of PLB muscles in healthy subjects during the gait cycle. METHODS: Thirty healthy subjects were recruited in a laboratory in this cross-sectional research design. While walking, electromyography (EMG) activity was measured from PLB via surface electrodes in six experimental conditions: 1) barefoot, 2) minimalist, 3) pronated control, 4) air chamber, 5) ethyl-vinyl-acetate (EVA) and 6) boost. These data were obtained and compared. RESULTS: The peroneus brevis showed significant reductions in the peak amplitude of the five footwear types (minimalist, pronation control, air chamber, EVA and boost) with respect to the barefoot condition in the propulsion phase of the gait cycle during walking (P = 0.034; P < 0.001; P < 0.001; P < 0.001; P = 0.006) and running (P = 0.004; P < 0.001; P = 0.001; P < 0.001; P = 0.001), respectively. Furthermore, peroneus longus showed significant reductions in the peak amplitude of these five footwear types with respect to the barefoot condition in the propulsion phase of the gait cycle during running (P = 0.005; P = 0.038; P = 0.019; P = 0.025; P = 0.021). CONCLUSION: The EMG activity patterns of the PLB muscles may depend on the use of different types of sport shoes such as minimalist, pronation control, air chamber, EVA and boost footwear with respect the barefoot condition in different phases of the gait cycle during walking and running. PMID- 29597145 TI - Collaboration or negotiation: two ways of interacting suggest how shared thinking develops. AB - This paper contrasts two ways that shared thinking can be conceptualized: as negotiation, where individuals join their separate ideas, or collaboration, as people mutually engage together in a unified process, as an ensemble. We argue that these paradigms are culturally based, with the negotiation model fitting within an assumption system of separate entities-an assumption system we believe to be common in psychology and in middle-class European American society-and the collaboration model fitting within a holistic worldview that appears to be common in Indigenous-heritage communities of the Americas. We discuss cultural differences in children's interactions-as negotiation or collaboration-that suggest how these distinct paradigms develop. PMID- 29597147 TI - Caffeic acid phenethyl ester down-regulates claudin-2 expression at the transcriptional and post-translational levels and enhances chemosensitivity to doxorubicin in lung adenocarcinoma A549 cells. AB - Claudin-2 is highly expressed in human lung adenocarcinoma cells and involved in the promotion of proliferation. Here, we searched for a compound, which can decrease claudin-2 expression using lung adenocarcinoma A549 cells. In the screening using compounds included in royal jelly and propolis, the protein level of claudin-2 was dose-dependently decreased by caffeic acid phenethyl ester (CAPE), whereas the mRNA level and promoter activity were only decreased by 50 MUM CAPE. These results suggest that CAPE down-regulates claudin-2 expression mediated by two different mechanisms. CAPE (50 MUM) decreased the level of p-NF kappaB, whereas it increased that of IkappaB. The CAPE-induced decrease in promoter activity of claudin-2 was blocked by the mutation in an NF-kappaB binding site. The inhibition of NF-kappaB may be involved in the decrease in mRNA level of claudin-2. The CAPE (10 MUM)-induced decrease in claudin-2 expression was inhibited by chloroquine, a lysosomal inhibitor. CAPE increased the expression and activity of protein phosphatase (PP) 1 and 2A. The CAPE-induced decrease in claudin-2 expression was blocked by cantharidin, a potent PPs inhibitor. The cell proliferation was suppressed by CAPE, which was partially rescued by ectopic expression of claudin-2. In addition, the toxicity and accumulation of doxorubicin in 3D spheroid cells were enhanced by CAPE, which was inhibited by ectopic expression of claudin-2. Taken together, CAPE down-regulates claudin-2 expression at the transcriptional and post-translational levels, and enhances sensitivity of cells to doxorubicin in 3D culture conditions. CAPE may be a useful adjunctive compound in the treatment of lung adenocarcinoma. PMID- 29597144 TI - Vitamin K: Redox-modulation, prevention of mitochondrial dysfunction and anticancer effect. AB - This review is directed to the redox-modulating properties and anticancer effect of vitamin K. The concept is focused on two aspects: (i) redox-cycle of vitamin K and its effect on the calcium homeostasis, "oncogenic" and "onco-suppressive" reactive oxygen species and the specific induction of oxidative stress in cancer; (ii) vitamin K plus C as a powerful redox-system, which forms a bypass between mitochondrial complexes II and III and thus prevents mitochondrial dysfunction, restores oxidative phosphorylation and aerobic glycolysis, modulates the redox state of endogenous redox-pairs, eliminates the hypoxic environment of cancer cells and induces cell death. The analyzed data suggest that vitamin C&K can sensitize cancer cells to conventional chemotherapy, which allows achievement of a lower effective dose of the drug and minimizing the harmful side-effects. The review is intended for a wide audience of readers - from students to specialists in the field. PMID- 29597148 TI - Methanol metabolism and archaeal community changes in a bioelectrochemical anaerobic digestion sequencing batch reactor with copper-coated graphite cathode. AB - In this study, the metabolism of methanol and changes in an archaeal community were examined in a bioelectrochemical anaerobic digestion sequencing batch reactor with a copper-coated graphite cathode (BEAD-SBRCu). Copper-coated graphite cathode produced methanol from food waste. The BEAD-SBRCu showed higher methanol removal and methane production than those of the anaerobic digestion (AD)-SBR. The methane production and pH of the BEAD-SBRCu were stable even under a high organic loading rate (OLR). The hydrogenotrophic methanogens increased from 32.2 to 60.0%, and the hydrogen-dependent methylotrophic methanogens increased from 19.5 to 37.7% in the bulk of BEAD-SBRCu at high OLR. Where methanol was directly injected as a single substrate into the BEAD-SBRCu, the main metabolism of methane production was hydrogenotrophic methanogenesis using carbon dioxide and hydrogen released by the oxidation of methanol on the anode through bioelectrochemical reactions. PMID- 29597149 TI - Influence of conductive material on the bioelectrochemical removal of organic matter and nitrogen from low strength wastewater. AB - The treatment of low strength wastewater that has the level of discharge standard for wastewater treatment plant was studied using an upflow bioelectrochemical reactor with an applied voltage of 0.6 V. The direct interspecies electron transfer (DIET) between electroactive bacteria was activated in the upflow bioelectrochemical reactor, which improved the substrate affinity of bacteria. The effluent qualities in COD and ammonia nitrogen was stable at less than 3.5 mg/L and 7.46 mg/L at 1 h of hydraulic retention time, respectively. The conductive materials, including conductive sheets and conductive particles, further increased the biomass retention and the DIET by altering the abundance of dominant bacterial groups. The effluent qualities in COD and ammonia nitrogen was improved up to 1.98 mg/L and 2.65 mg/L, respectively, by the conductive sheets. The upflow bioelectrochemical reactor with conductive materials is a good tertiary treatment process for improving the quality of the final effluent discharged from wastewater treatment plant. PMID- 29597150 TI - Metagenomic insight into methanogenic reactors promoting direct interspecies electron transfer via granular activated carbon. AB - To provide insight into direct interspecies electron transfer via granular activated carbon (GAC), the effect of GAC supplementation on anaerobic digestion was evaluated. Compared to control samples, the GAC supplementation increased the total amount of methane production and its production rate by 31% and 72%, respectively. 16S rDNA sequencing analysis revealed a shift in the archaeal community composition; the Methanosarcina proportion decreased 17%, while the Methanosaeta proportion increased 5.6%. Metagenomic analyses based on shotgun sequencing demonstrated that the abundance of pilA and omcS genes belonging to Geobacter species decreased 69.4% and 29.4%, respectively. Furthermore, the analyses suggested a carbon dioxide reduction pathway rather than an acetate decarboxylation pathway for methane formation. Taken together, these results suggest that GAC improved methane production performance by shifting the microbial community and altering functional genes associated with direct interspecies electron transfer via conductive materials. PMID- 29597151 TI - Purchases of prescription drugs before an alcohol-related death: A ten-year follow-up study using linked routine data. AB - BACKGROUND: Physician's intention to prescribe drugs could potentially be used to improve targeting of alcohol interventions and enhanced disease management to patients with a high risk of severe alcohol-related harm within outpatient settings. METHODS: Comparison of ten-year incidence trajectories of 13.8 million reimbursed purchases of prescription drugs among 303,057 Finnish men and women of whom 7490 ultimately died due to alcohol-related causes (Alc+), 14,954 died without alcohol involvement (Alc-), and 280,613 survived until the end of 2007. RESULTS: 5-10 years before death, 88% of the persons with an Alc+ death had received prescription medication, and over two-thirds (69%) had at least one reimbursed purchase of drugs for the alimentary tract and metabolism, the cardiovascular system, or the nervous system. Among persons with an Alc+ death, the incidence rate (IR) for purchases of hypnotics, and sedatives was 1.38 times higher (95% confidence interval (CI):1.32,1.44) compared to those with an Alc- death, and 4.07 times higher (95%CI:3.92,4.22) compared to survivors; and the IR for purchases of anxiolytics was 1.40 times higher (95%CI:1.34,1.47) compared to those with an Alc- death, and 3.61 times higher (95%CI:3.48,3.78) compared to survivors. CONCLUSIONS: Using physician's intention to prescribe drugs affecting the alimentary tract and metabolism, cardiovascular system and nervous system could potentially be used to flag patients who might benefit from screening, targeted interventions or enhanced disease management. In particular, patients who are to be prescribed anxiolytics, hypnotics, and sedatives, and antidepressants may benefit from enhanced interventions targeted to problem drinking. PMID- 29597152 TI - Biogenic porous silica and silicon sourced from Mexican Giant Horsetail (Equisetum myriochaetum) and their application as supports for enzyme immobilization. AB - Porous silica-based materials are attractive for biomedical applications due to their biocompatibility and biodegradable character. In addition, inorganic supports such as porous silicon are being developed due to integrated circuit chip compatibility and tunable properties leading to a wide range of multidisciplinary applications. In this contribution, biosilica extracted from a rarely studied plant material (Equisetum Myriochaetum), its conversion to silicon and the potential for both materials to be used as supports for enzyme immobilization are investigated. E. myriochaetum was subject to conventional acid digestion to extract biogenic silica with a% yield remarkably higher (up to 3 times) than for other Equisetum sp. (i.e. E. Arvense). The surface area of the isolated silica was ~400 m2/g, suitable for biotechnological applications. Biogenic silicon was obtained by magnesiothermic reduction. The materials were characterized by SEM-EDX, XRD, FT-IR, ICP-OES, TGA and BET analysis and did not contain significant levels of class 1 heavy elements (such as Pb, Cd, Hg and As). Two commercial peroxidases, horseradish peroxidase (HRP) and Coprinus cinereus peroxidase (CiP) were immobilized onto the biogenic materials using three different functionalization routes: (A) carbodiimide, (B) amine + glutaraldehyde and (C) amine + carbodiimide. Although both biogenic silica and porous silicon could be used as supports differences in behaviour were observed for the two enzymes. For HRP, loading onto biogenic silica via the glutaraldehyde immobilization technique (route B) was most effective. The loading of CiP showed a much higher peroxidase activity onto porous silicon than silica functionalized by the carbodiimide method (route A). From the properties of the extracted materials obtained from Equisetum Myriochaetum and the immobilization results observed, these materials appear to be promising for industrial and biomedical applications. PMID- 29597153 TI - Synthesis and interaction of sterol-uridine conjugate with DMPC liposomes studied by differential scanning calorimetry. AB - Differential scanning calorimetry (DSC) is a thermoanalytical technique which provides information on the interaction between drugs and models of cell membranes. Studies on the calorimetric behavior of hydrated phospholipids within liposomes are employed to shed light on the changes in the physico-chemical properties when interacting with drugs. In this report, new potential anti-cancer drugs such as uridine and uridine derivatives (acetonide and its succinate), 3beta-5alpha,8alpha-endoperoxide-cholestan-6-en-3-ol (5,8-epidioxicholesterol) and conjugate (uridine acetonide-epidioxicholesterol succinate) have been synthesized. Steglich esterification method using coupling agents allowed to obtain the uridine acetonide-sterol conjugate. The study on the interaction between the drugs and dimiristoyl-phophatidilcholine (DMPC) liposomes has been conducted by the use of DSC. The analysis of the DSC curves indicated that the uridine and derivatives (acetonide and its succinate) present a very soft interaction with the DMPC liposomes, whereas the 5,8-epidioxicholesterol and the conjugate showed a strong effect on the thermotropic behavior. Our results suggested that the lipophilic character of uridine acetonide-sterol conjugate improves the affinity with the DMPC liposomes. PMID- 29597154 TI - Cationic polymeric N-halamines bind onto biofilms and inactivate adherent bacteria. AB - A series of amine-based cationic polymeric N-halamine precursors, poly(2,2,6,6 tetramethyl-4-piperidyl methacrylate-co-trimethyl-2-methacryloxyethylammonium chloride)(PMPQ), were synthesized by copolymerizing 2,2,6,6-tetramethyl-4 piperidyl methacrylate (TMPM) with trimethyl-2-methacryloxyethylammonium chloride (TMAC) at different molar ratios (TMPM:TMAC = 10:90,30:70,50:50,70:30, and 90:10). After chlorine bleach treatment, the TMPM moieties in the new copolymers were transformed into amine-based N-halamines (Cl-PMPQ). The chemical structures of the samples were characterized with 1H NMR, FT-IR, and UV spectra, and the molecular weights were determined by dynamic light scattering (DLS). With lower than 70 mol% of the original TMPM content, the resulting Cl-PMPQ copolymers were soluble in water, and demonstrated potent antibacterial functions against Escherichia coli (E. coli, a representative Gram-negative bacteria) and Staphylococcus epidermidis (S. epidermidis, a representative Gram-positive bacteria). E. coli and S. epidermidis were allowed to form biofilms on glass slides. Zeta potential analyses demonstrated that the Cl-PMPQ copolymers rapidly adsorbed onto the preexisting biofilms, and bacterial culturing studies confirmed that the bound Cl-PMPQ provided a total kill of the adherent bacteria in the biofilms. The kinetics of the Cl-PMPQ binding onto the preexisting biofilms were studied with UV analyses. The data fitted well to the bimodal model. The binding kinetic parameters of Cl-PMPQ onto the bacterial biofilms were thus determined. PMID- 29597155 TI - Dynamic wetting of human blood and plasma on various surfaces. AB - Surface fouling from coagulated blood is a major challenge in medical industry. However, the wetting physics and dynamics of blood on surfaces are not well understood nor are the quantitative influences due to surface and fluid properties. The present study investigates the effect of surface wetting and dynamics resulting for human blood and plasma, namely hemophobicity, on surfaces with different wettability. To examine effects of fluid properties, the wetting characteristics for liquids with Ohnesorge number similar to that of blood and plasma are also considered. Among the tested surfaces, a superhydrophobic, non fluorinated, nanocomposite coating based on an inexpensive spray application of a polymer/nanoparticle dispersion provided a very high degree of blood and plasma repellency. This was evidenced by advancing contact angles greater than 153 degrees and roll-off angles less than 18 degrees , for both fluids, and no evidence of a blood trail. However, air exposure during the contact angle measurements led to the formation of a thin gel-like protein skin on the surface (even though an anti-coagulant was added), which distorted the receding droplet curvature. This previously unreported feature did not modify the static contact angle but appears to have caused a significant increase in contact angle hysteresis.

AB - Ranitidine (RNT) has been an important tertiary amine precursor of N nitrosodimethylamine (NDMA) in chlorine-based water treatment, due to reaction with monochloramine (NH2Cl) with exceptionally high molar yields up to 90%. This study examined the effects of nitrite ions (NO2-) on the kinetics of NDMA formation during the chloramination of RNT under variable concentrations of dissolved oxygen (DO, 0.7-7.5mg/L), RNT (5-30MUM), NH2Cl (5-20mM), NO2- or NO3- (0-2mM) and pH (5.6-8.6). In the absence of the NO2-, the ultimate molar yield of NDMA after 6h of reaction was primarily influenced by [DO] and pH, while marginally affected by initial [RNT] and [NH2Cl]. A kinetic model, prepared in accordance with the reaction sequence of NDMA formation, suggested that the rate determining step was accelerated with increasing [NH2Cl]0, [DO], and pH. A Kinetic study together with ultra-performance liquid chromatography-quadrupole time of flight mass spectrometer (UPLC-Q-TOF MS) and gas chromatography (GC)/TOF MS analyses in parallel demonstrated that the nitrite ion inhibited the nucleophilic substitution of the terminal amine on NH2Cl, and reduced the pseudo steady state concentration of N-peroxyl radicals, significantly decreasing the ultimate yields of NDMA.

AB - Detailed descriptions of the development of the hippocampus promise to shed light on the neural foundation of development of memory and other cognitive functions, as well as the emergence of major mental disorders. Hippocampus is a heterogeneous structure with a well characterized internal complexity, but development of its distinct subregions in humans has remained poorly described. We analyzed magnetic resonance imaging (MRI) data from a large longitudinal sample (270 participants, 678 scans) using an automated segmentation tool and mixed models to delineate the development of hippocampal subregion volumes from childhood to adulthood. We also examined sex differences in subregion volumes and their development, and associations between hippocampal subregions and general cognitive ability. Nonlinear developmental trajectories with early volume increases were observed for subiculum, cornu ammonis (CA) 1, molecular layer (ML) and fimbria. In contrast, parasubiculum, presubiculum, CA2/3, CA4 and the granule cell layer of the dentate gyrus (GC-DG) showed linear volume decreases. No sex differences were found in hippocampal subregion development. Finally, general cognitive ability was positively associated with CA2/3 and CA4 volumes, as well as with ML development. In conclusion, hippocampal subregions appear to develop in diversified ways across adolescence, and specific subregions may link to general cognitive level. PMID- 29597158 TI - De-coupling interannual variations of vertical dust extinction over the Taklimakan Desert during 2007-2016 using CALIOP. AB - During the springtime, mineral dust from the Taklimakan Desert (TD) is lifted up to high altitudes and transported long distances by the westerlies. The vertical distributions of Taklimakan dust are important for both long-range transport and climate effects. In this study, we use CALIOP Level 3 dust extinction to describe interannual variation of dust extinction in TD aggregated at each 1km interval (1 2km, 2-3km, 3-4km, 4-5km and 5-6km) above mean sea level during springtime from 2007 to 2016. 87% of dust extinction over TD is concentrated at 1-4km taking a major composition of dust aerosol optical depth (AOD) and only 8.1% dust AOD is at 4-6km. Interannual variation of seasonal and monthly dust extinction at 1-4km is almost as same as dust AOD (R>0.99) but different from that at 4-6km (R are around 0.42). Our analysis provides observational evidence from CALIOP that vertical dust extinction over TD has distinctively different variability below and above 4km altitude and this threshold divides dust transport in TD into two systems. Taklimakan dust aerosols are more related to dust transport at high altitudes (4-10km) than low altitudes (0-4km) over downwind regions. High dust extinction below 4km over TD is necessary but not sufficient conditions to ensure dust transport easterly, while high dust extinction levels at 4-6km over TD are both necessary and sufficient conditions; such contrast leads to the de-coupled interannual variability seen by CALIOP. PMID- 29597159 TI - Effects of increasing atmospheric CO2 on the marine phytoplankton and bacterial metabolism during a bloom: A coastal mesocosm study. AB - Increases of atmospheric CO2 concentrations due to human activity and associated effects on aquatic ecosystems are recognized as an environmental issue at a global scale. Growing attention is being paid to CO2 enrichment effects under multiple stresses or fluctuating environmental conditions in order to extrapolate from laboratory-scale experiments to natural systems. We carried out a mesocosm experiment in coastal water with an assemblage of three model phytoplankton species and their associated bacteria under the influence of elevated CO2 concentrations. Net community production and the metabolic characteristics of the phytoplankton and bacteria were monitored to elucidate how these organisms responded to CO2 enrichment during the course of the algal bloom. We found that CO2 enrichment (1000MUatm) significantly enhanced gross primary production and the ratio of photosynthesis to chlorophyll a by approximately 38% and 39%, respectively, during the early stationary phase of the algal bloom. Although there were few effects on bulk bacterial production, a significant decrease of bulk bacterial respiration (up to 31%) at elevated CO2 resulted in an increase of bacterial growth efficiency. The implication is that an elevation of CO2 concentrations leads to a reduction of bacterial carbon demand and enhances carbon transfer efficiency through the microbial loop, with a greater proportion of fixed carbon being allocated to bacterial biomass and less being lost as CO2. The contemporaneous responses of phytoplankton and bacterial metabolism to CO2 enrichment increased net community production by about 45%, an increase that would have profound implications for the carbon cycle in coastal marine ecosystems. PMID- 29597160 TI - Distribution and risk assessment of banned and other current-use pesticides in surface and groundwaters consumed in an agricultural catchment dominated by cocoa crops in the Ankobra Basin, Ghana. AB - The existence of pesticides, such as organochlorine pesticides, parathion-ethyl, methamidophos which is banned globally and some current-use non-banned pesticides of organophosphorus and synthetic pyrethroids in freshwater sources is an ecological and public health concern in many countries, including Ghana. Prompted by this concern, the exposure levels and risk assessment of these pesticides to humans and non-target organisms via groundwater and surface water sources in an agricultural catchment dominated by cocoa crops in the Ankobra Basin, Ghana, were investigated. The individual concentrations of the banned pesticides in the surface water and groundwater samples varied from < LOD to 0.110 MUg/L and < LOD to 0.055 MUg/L, respectively, while the concentrations of the non-banned pesticides ranged from < LOD to 0.925 MUg/L and < LOD to 2 MUg/L, respectively. The mean concentrations of chlorpyrifos, cypermethrin, p,p'-DDT and pirimiphos methyl in some water sources exceeded the EU limit of 0.1 MUg/L. Some surface water sources were more contaminated with DDTs, endrin, dieldrin, methoxychlor, chlorpyrifos, and HCH isomers than were freshwater sources in river basins in some countries of the world. Chlorpyrifos, p,p'-DDT and methoxychlor were ubiquitous in both water sources. The hydrochemical and compositional profiles of the pesticides indicate that water-exchange and secondary porosities in the bedrock likely contributed to the occurrence of the pesticides in the water sources. The pesticides were of low risk to humans that consume the water, but considering the US EPA safe limit for carcinogenic effects of 10-6, the high levels of DDTs, beta-HCH, and dieldrin in some of the surface water and groundwater sources may cause cancer in children or infants. The toxicity of pesticide mixtures to surface water non-target organisms decreased in the order of fish > Daphnia magna > algae. The pesticides in the water sources were anthropogenic in origin and recently used. DDT and HCH in the water were of technical-grade origin. PMID- 29597161 TI - Ammonia oxidizers and nitrite-oxidizing bacteria respond differently to long-term manure application in four paddy soils of south of China. AB - Nitrification plays an important role in the soil nitrogen (N) cycle, and fertilizer application may influence soil nitrifiers' abundance and composition. However, the effect of long-term manure application in paddy soils on nitrifying populations is poorly understood. We chose four long-term manure experimental fields in the south of China to study how the abundance and community structure of nitrifiers would change in response to long-term manure application using quantitative PCR and Miseq sequencing analyses. Our results showed that manure application significantly increased ammonia oxidizing archaea (AOA) abundance at the ChangSha (CS) and NanChang (NC) sites, while the abundance of ammonia oxidizing bacteria (AOB) represented 4.8- and 12.8- fold increases at the JiaXing (JX) and YingTan (YT) sites, respectively. Miseq sequencing of 16S rRNA genes indicated that manure application altered the community structure of nitrifying populations, especially at the NC and YT sites. The application of manure significantly changed AOA and nitrite oxidizing bacteria (NOB) community structures but not those of AOB, suggesting that AOA and NOB may be more sensitive to manures. Variation partitioning analysis (VPA) and redundancy analysis (RDA) indicated that soil pH, TN, NO3--N and water content were the main factors in shaping nitrifying communities. These findings suggest that nitrifiers respond diversely to manure application, and soil physiochemical properties play an important role in determining nitrifiers' abundance and communities with long term manure addition. PMID- 29597162 TI - Metal concentrations in traditional and herbal teas and their potential risks to human health. AB - Food and beverage consumption is an important route for human exposure to metals. Traditional tea (Camellia sinensis) is a widely-consumed beverage, which may contain toxic metals. This study determined total and infusion concentrations of 5 metals including Al, As, Cd, Cr, and Pb in 47 traditional and herbal teas from 13 countries and assessed their potential risks to human health. The data showed that herbal teas exhibited higher As (0.26mgkg-1), Cd (0.19mgkg-1) and Pb (2.32mgkg-1) than traditional teas. Black tea from India had high Cr at 31mgkg-1 while white tea from China had low Cr at 0.39mgkg-1. Arsenic, Cd and Pb did not exceed the WHO limit for medicinal plants excluding one herbal tea with 1.1mgkg-1 As and 26.4mgkg-1 Pb. However, Cr in 47% herbal teas and 73% traditional teas exceeded the Canada limit of 2mgkg-1. Metal concentrations in tea infusions were below the MCL for drinking water except for Al. Total Al and its infusion was lower in herbal teas (47-1745mgkg-1 and 0.09-3.95mgL-1) than traditional teas (50.3-2517mgkg-1 and 0.02-7.51mgL-1), with 0.9-22% and 4-49% of the Al being soluble in infusion. The Al concentrations in infusion in all black tea and 83, 75 and 25% of the green, oolong and herbal teas exceeded the secondary MCL for drinking water at 0.2mgL-1. However, the weekly intake of Al from drinking tea (0.001-0.39 and 0.003-0.56mgkg-1 for children and adults) was lower than the provisional tolerable weekly intake for Al at 1.0mgkg-1. Our data showed that it is important to consider metal intake from tea consumptions, especially for Cr and Al in heavy tea drinkers. PMID- 29597163 TI - Impact of highway construction on land surface energy balance and local climate derived from LANDSAT satellite data. AB - Extensive construction of highways has a major impact on the landscape and its structure. They can also influence local climate and heat fluxes in the surrounding area. After the removal of vegetation due to highway construction, the amount of solar radiation energy used for plant evapotranspiration (latent heat flux) decreases, bringing about an increase in landscape surface temperature, changing the local climate and increasing surface run-off. In this study, we evaluated the impact of the D8 highway construction (Central Bohemia, Czech Republic) on the distribution of solar radiation energy into the various heat fluxes (latent, sensible and ground heat flux) and related surface functional parameters (surface temperature and surface wetness). The aim was to describe the severity of the impact and the distance from the actual highway in which it can be observed. LANDSAT multispectral satellite images and field meteorological measurements were used to calculate surface functional parameters and heat balance before and during the highway construction. Construction of a four-lane highway can influence the heat balance of the landscape surface as far as 90m in the perpendicular direction from the highway axis, i.e. up to 75m perpendicular from its edge. During a summer day, the decrease in evapotranspired water can reach up to 43.7m3 per highway kilometre. This means a reduced cooling effect, expressed as the decrease in latent heat flux, by an average of 29.7MWh per day per highway kilometre and its surroundings. The loss of the cooling ability of the land surface by evaporation can lead to a rise in surface temperature by as much as 7 degrees C. Thus, the results indicate the impact of extensive line constructions on the local climate. PMID- 29597164 TI - Presence and impact of Stockholm Convention POPs in gull eggs from Spanish and Portuguese natural and national parks. AB - The aim of the present work was to comparatively assess the occurrence and impact of persistent organic pollutants (POPs) in nine natural and national parks from Spain and Portugal using gull eggs (Larus michahellis and L. audouinii) as bioindicators of environmental contamination. Sampling was performed during the breeding season of 2016. Compounds studied include polychlorinated biphenyls (PCBs), organochlorinated pesticides (OC pesticides), perfluorooctane sulfonic acid (PFOS) and polybrominated diphenyl ethers (PBDEs), and were analyzed using mass spectrometric based techniques. The results showed a high contamination by PCBs in all colonies, with total levels ranging from 59 to 1278ng/g wet weight (ww), despite their use is not currently authorized. OC pesticides were also present in all colonies, with a high incidence of 4,4'-DDE in gull eggs at levels up to 218+/-50ng/g ww in L. michahellis and 760+/-412ng/g ww in L. audouinii from the Ebro Delta natural park. PBDEs and PFOS were also detected at levels up to 91.7+/-21.3ng/g ww, which can be attributed to a more recent use. Except for PBDEs, the POP levels in eggs from L. audouinii were higher than in L. michahellis, presumably associated to the fish-based diet of the former. Finally, the effect of POP levels on eggshell parameters (volume, eggshell thickness and desiccation index) were investigated for each colony and gull species in order to evaluate the egg viability and, therefore, the reproduction success. PMID- 29597165 TI - Simulating stream response to floodplain connectivity and revegetation from reach to watershed scales: Implications for stream management. AB - Natural-infrastructures (e.g., floodplains) can offer multiple ecosystem services (ES), including flood-resilience and water quality improvement. In order to maintain these ES, state and non-profit organizations consider various stream interventions, including increased floodplain connectivity and revegetation. However, the effect of these interventions is rarely quantified. We build a hydraulic model to simulate the influence of above-mentioned interventions on stream power and water depth during 5 yr and 100 yr flood return-intervals for two watersheds in Vermont, USA. Simulated revegetation of floodplains increased water depth and decreased stream power, whereas increasing connectivity resulted in decline of both responses. Combination of increased connectivity and floodplain revegetation showed greatest reduction in stream-power suggesting that interventions may influence stream response in diverse ways. Across all three interventions, 14% and 48% of altered reaches showed increase in stream power and water depth over baseline, indicating that interventions may lead to undesirable outcomes and their apparent effectiveness can vary with the measure chosen for evaluation. Interventions also influenced up to 16% of unaltered reaches (i.e., in which no interventions were implemented), indicating the consequences of interventions can spread both up and downstream. Multivariate analysis showed that up to 50% of variance in stream response to interventions is attributable to characteristics of reaches, indicating that these characteristics could mediate the effectiveness of interventions. This study offers a framework to evaluate the potential ES provided by natural infrastructure. All stream interventions involve tradeoffs among responses and between target and non-target areas, so careful evaluation is therefore needed to compare benefits and costs among interventions. Such assessments can lead to more effective management of stream-floodplain ecosystems both in Vermont and elsewhere. PMID- 29597166 TI - Synthesis of novel ring-contracted artemisinin dimers with potent anticancer activities. AB - Artemisinin is a potential anticancer agent with an interesting trioxane sesquiterpene structure. In order to improve the biological activity and metabolic stability of artemisinin, a series of novel ring-contracted artemisinin dimers were synthesized. These dimers were evaluated by MTT assay against six cancer cell lines. Most of the dimmers exhibited improved antiproliferative activities over artemisinin. Especially, compound 8b showed the most pronounced anti-cancer activity for PC12 cancer cells with an IC50 value of 1.56 MUM. Thus, PC12 cancer cells were used to further investigate the mechanism of antiproliferation for this series of compounds. Compound 8b arrested cell cycle at G1 phase and induced cell apoptosis via up-regulation of Bad, Bax, caspase-3 and caspase-9 protein expressions while inhibiting the expression of Bcl-xL. The present studies are the first to synthesize the ring-contracted artemisinin as dimers and show that these dimers have potent anti-tumor activities against several cancer cell lines. PMID- 29597167 TI - Engineering a novel protease-based Exendin-4 derivative for type 2 antidiabetic therapeutics. AB - To develop an effective long-acting antidiabetic agent, we designed a novel Exendin-4 derivative (termed LEx4) containing an albumin-binding domain (ABD), a protease-cleavable linker and a native Exendin-4. Here, we present the LEx4 with balanced glucoregulatory activity and prolonged in vivo activity. As a first step, the LEx4 with purity more than 99% was prepared. Microscale thermophoresis (MST) results demonstrated that LEx4 associates with rat and monkey serum albumin with high-affinity (Ka = 1.26 * 106 M-1 and 1.52 * 106 M-1, respectively). Then the stability test in vitro showed the enhanced antiproteolytic ability of LEx4 in rat and human plasma compared to native Exendin-4. Oral glucose tolerance test (OGTT) in type 2 diabetic mice showed the glucose-lowering efficacy of LEx4 was clearly dosage-dependent within 25-250 nmol/kg. In addition, the protracted antidiabetic effects of LEx4 were further confirmed by both multiple OGTTs and hypoglycemic efficacies test in type 2 diabetic mice. In Sprague Dawley (SD) rats, LEx4 also showed 3.3-fold longer elimination half-life (t1/2) than native Exendin-4. Furthermore, once daily injection of LEx4 to db/db mice achieved long term beneficial effects on body weight, blood biochemical values, glucose tolerance and pancreatic tissue. We believe LEx4 has superior pharmaceutical potential as a therapeutic drug to against type-2 diabetes mellitus (T2DM) based on these results. This strategy of albumin binding is also applicable to other bioactive peptides for development of long-acting therapeutic drugs.

AB - Highly efficient poly functionalized pyrrolo[3,2-a]carbazoles via ring contraction through rearrangement and intramolecular Michael addition reaction using one pot multicomponent reaction (MCR) is reported for the first time. Free radical scavenging and anticancer activities were determined by DPPH and MTT assays respectively. Of these, compound 8d exhibited most potent activity against HCT-15 human colon cancer cell lines with an IC50 value of 9.9 MUM and low toxicity toward normal human red blood cells. The morphological changes were visualized using scanning electron microscopy (SEM) technique, intracellular ROS generation measured by spectrofluorometer and gene expression levels of caspase 3, caspase-9 and Bcl-2 were determined using Semi quantitates PCR analysis for the target compound. Further, the structure activity relationships were also carried out. The results of the present study revealed that among pyrrolo[3,2 a]carbazole compounds, 7-chloro-2-oxo-3a-(2'-oxo-2',3'-dihydro-1'H-indol-3'-yl) 2,3,3a,4,5,10-hexahydro-pyrrolo[3,2-a]carbazole-1-carbonitrile could be exploited as an excellent anticancer agent against colon cancer cells. PMID- 29597169 TI - Synthesis and evaluation of novel coumarin-oxime ethers as potential anti tubercular agents: Their DNA cleavage ability and BSA interaction study. AB - As a contribution to the development of novel coumarin-oxime ether conjugates with therapeutically interesting properties, a series of coumarin-oxime ether (1a 1j) was synthesised using SN2 reaction of bromomethyl coumarins with butane-2,3 dione monoxime. Invitro anti-tuberculosis activityagainstMTBH37Rv strain was established for the coumarin-oxime ether (1a-1j). Most of the compounds exhibited significant activity with minimum inhibitory concentration (MIC)in the range of 0.04-3.12 MUg mL-1. Compound (1h) was identified as a hit candidate exhibiting MIC of 0.04 MUg mL-1, closer to the MIC value of Isoniazid (0.02 MUg mL-1), a commercially available drug for the treatment of tuberculosis. Compound 1h also displayed a low level of toxicity in Vero cells along with a good safety profile in vitro. Compounds that showed potent anti-tubercular activity were also found to cleave DNA more efficiently and thereby exhibit nuclease activity. The most active compound (1h) was further studied to deduce the mode of interaction with model serum protein, bovine serum albumin (BSA). PMID- 29597170 TI - Identification of multi-target inhibitors of leukotriene and prostaglandin E2 biosynthesis by structural tuning of the FLAP inhibitor BRP-7. AB - Leukotrienes (LTs) and prostaglandin (PG)E2 are enzymatically produced from arachidonic acid and represent highly bioactive lipid mediators with pro inflammatory functions. Here, we report on novel multi-target inhibitors that potently and dually interfere with 5-lipoxygenase-activating protein (FLAP) and microsomal prostaglandin E2 synthase (mPGES)-1 in LT and PGE2 biosynthesis, based on the previously identified selective FLAP inhibitor BRP-7 (8, IC50 = 0.31 MUM). C (5)-substitution of the benzimidazole ring of BRP-7 by carboxylic acid and its bioisosteres provided compounds, exemplified by 57 that potently suppress LT formation (IC50 = 0.05 MUM) by targeting FLAP along with inhibition of mPGES-1 (IC50 = 0.42 MUM). Besides FLAP, also 5-lipoxygenase (5-LO) and LTC4 synthase activities were inhibited by 57, albeit with lower potency (IC50 = 0.6 and 6.2 MUM) than FLAP. Docking studies and molecular dynamic simulations with FLAP, mPGES-1 and 5-LO provide valuable insights into potential binding interactions of the inhibitors with their targets. Together, these novel benzimidazole derivatives may possess potential as leads for development of effective anti inflammatory drugs with multi-target properties for dually inhibiting LT and PGE2 production. PMID- 29597171 TI - N,N'-disubstituted cinnamamide derivatives potentiate ciprofloxacin activity against overexpressing NorA efflux pump Staphylococcus aureus 1199B strains. AB - A multi-step procedure has been described which afforded satisfactory yields of N,N'-disubstituted cinnamamides derived from N-Boc-protected amino acids (Boc Gly, Boc-Val, Boc-Phe). The key step of this synthesis was a regioselective RedAl reduction of an amide function in presence of a carbamate group. Next, these cinnamamides were evaluated in co-admnistration with ciprofloxacin as efflux pump inhibitors against two S. aureus strains, NorA overexpressing SA1199B and wild type SA1199. In parallel, their intrinsic toxicity was appreciated on human lung fibroblast MRC5 cells. Therefore, the cinnamamide combining both carbamate and indol-3-yl groups, was found to be the most active and one of the less toxic EPI and constituted a promising hit.

AB - The sulfite-mediated photoreduction (SMP) with UV-C light showed promising performances especially for dechlorination of chlorinated organic compounds (e.g., 2, 4, 6-trichlorophenol (TCP)).

PMID- 29597172 TI - Differences in the bioaccumulation of selenium by two earthworm species (Pheretima guillemi and Eisenia fetida). AB - Information on the bioaccumulation of selenium (Se) in soil invertebrates (e.g. earthworms) is rather scarce. In the present study, bioaccumulation of Se in two eco-physiologically different earthworms, namely anecic Pheretima guillemi and epigeic Eisenia fetida, was determined after 28 days exposure to a successive doses of Se-spiked soil, specifically 0.5, 5, 50, and 200 MUg Se g-1 soil. The results showed that Se concentration in earthworms elevated with increasing exposure levels, and maximums were up to 54.6 and 83.0 MUg g-1 dry weight in Pheretima guillemi and Eisenia fetida, respectively, after 4 weeks exposure to 200 MUg Se g-1 soil. Exposure to Se caused significant inhibition on earthworm growth, with the fresh weight loss ranging from 8.9% to 80.5%. Bioaccumulation factors (BAFs), empirically-derived and non-steady state, ranged from 0.12 to 4.17 and generally declined at higher exposure levels. Moreover, BAFs of Pheretima guillemi were higher than those of Eisenia fetida in low-dose Se-spiked soils, but the opposite was true in high-dose soils, indicating there is a species-specific response to exposure of Se between different earthworms. Further research is thus needed to reveal the accumulation pattern of Se in a wider range of earthworm species other than Eisenia fetida, which allows a better risk assessment of excessive Se to soil invertebrates and higher order organisms. PMID- 29597174 TI - Enhanced cesium removal from real matrices by nickel-hexacyanoferrate modified activated carbons. AB - After nuclear disasters, radioactive cesium partitions to soils and surface water, where it decays slowly. Hexacyanoferrates (HCFs) have excellent cesium removal properties but their structure is typically powdery. Many carrier materials, such as biomass or magnetic particles, have been used to provide a suitable substrate for HCFs that can be used in filters. This research uses the sorption properties of activated carbon (AC) to incorporate Ni-HCF, resulting in good structural properties of the hybrid material. These HCF-modified ACs show drastically improved sorption properties towards Cs after one, two and three HCF impregnation cycles. The activated carbon from brewer's spent grain with one modification cycle removes more than 80% of 1 mg L-1 Cs in a sea water solution and more than 98% of 1 mg L-1 Cs from surface water at a low AC dosage (0.5 g L 1). Iron and nickel leaching is studied and found to be dependent on the type of modified AC used and the leaching solution. Iron leaching can be problematic in surface and seawater, whereas nickel leaching is especially pronounced in seawater. PMID- 29597175 TI - Seasonal variation in the bacterial community composition of a large estuarine reservoir and response to cyanobacterial proliferation. AB - This study employed high-throughput sequencing (HTS) to understand the variations in microbial community in the largest estuary reservoir located at the Yangtze River for a year. Correlations between the heterotrophic bacterial and cyanobacterial communities in the estuarine ecosystem were also investigated. Significant spatial and temporal changes were observed in the microbial community composition at all sites. These differences were mainly reflected on the variations of bacterial relative abundance. The modularity analysis on the network indicate that bacterial community response to the variations of environmental factors in the form of co-occurrence/exclusion patterns. In warm season, Synechococcus spp. being the dominant Cyanobacteria taxa exhibited high relative abundance in the reservoir. Water temperature was the critical driver for the proliferation of Synechococcus. Moreover, heterotrophic bacteria belonging to Actinobacteria, Proteobacteria (alpha-, beta-, and gamma Proteobacteria), Bacteroidetes and Chlorobi, exhibited positive correlations with Synechococcus. The co-occurrence of these bacterial OTUs suggests that specific taxa may benefit from the proliferation of Synechococcus. In cold season, bacterial OTUs belonging to Actinobacteria and Bacteroidetes shown co-occurrence pattern with salt ions (including K+, Na+, Mg2+, Ca2+, Cl- and SO42-) inside the reservoir. In conclusion, further research is required to investigate the ecological functions of these taxa in estuarine ecosystems. PMID- 29597176 TI - Effect of disinfectant residual on the interaction between bacterial growth and assimilable organic carbon in a drinking water distribution system. AB - Public health is threatened by deteriorated water quality due to bacterial regrowth and uncontrolled growth-related problems in drinking water distribution systems (DWDSs). To investigate the scope of this problem, a two-year field study was conducted in south China. The amount of assimilable organic carbon (AOC), total cell concentrations (TCC), and intact cell concentrations (ICC) of water samples were determined by flow cytometry. The results indicated that ICC was significantly correlated to AOC concentration when the chlorine concentration was less than 0.15 mg/L, and ICC was lower at chlorine concentrations greater than 0.15 mg/L, suggesting that free chlorine level had effect on AOC and ICC. To further analyze the effect of disinfectant on AOC and bacterial growth, we designed an orthogonal experiment with different dosages of two commonly used disinfectants, chlorine and chloramine. The results demonstrated that high concentrations of free chlorine (>0.15 mg/L) and chloramine (>0.4 mg/L) were associated with relatively low proportions of intact cells and cultivable bacteria. Compared with chlorine, chloramine tended to cause lower AOC level and intact cells, likely because the chlorinated disinfection byproducts (DBPs) were more easily absorbed by bacteria than the chloraminated DBPs. Based on the statistical analysis of 240 water samples, ICC was limited when AOC concentration was less than 135 MUg/L, while temperature and the number of small-size particles showed positive effects on ICC (P<0.05). We conclude that the use of chloramine and controlling particle numbers should be suitable strategies to limit bacterial regrowth. PMID- 29597177 TI - Potential for biomonitoring metals and metalloids using fish condition and tissue analysis in an agricultural and coal mining region. AB - Agricultural and mining activities contribute to metal inputs in freshwater ecosystems around the world, which can in turn bioaccumulate in biota such as fish. Monitoring of metals loads in biota thus provides insight into the concentrations of bioavailable metals within the environment. Little research has been conducted on the potential of Australian freshwater fish for biomonitoring metals. Within the Fitzroy Basin of Central Queensland, a major agricultural and coal mining region, three commonly-encountered fish taxa were analysed for tissue metal loads. Arsenic concentrations in Nematalosa erebi and Melanotaenia splendida splendida tissue were elevated (above Food Standards Australia and New Zealand (FSANZ) guidelines), with highest concentrations in N. erebi liver tissue (up to 5.14 MUg/g). Lead concentrations were above the FSANZ guidelines in all three fish taxa analysed, with highest concentrations in Hypseleotrid full-body tissue (up to 5.99 MUg/g). Selenium in M. s. splendida and N. erebi tissue was positively correlated with total selenium in water (p < 0.05; r = 0.68 and 0.87 respectively). Environmental boron, selenium and nickel concentrations were positively correlated with N. erebi liver tissue metals. N. erebi hepatosomatic index was negatively correlated with dissolved arsenic, manganese, and total phosphorus (in water). The results highlight that M. s. splendida and N. erebi yield bioindicators which are responsive to environmental metals, and thus have potential for use in biomonitoring metals. The two species are also widespread along the east coast of Australia, there is thus a strong potential for applying the results to other regions within Australia.

AB - In this study, honeybee colonies were monitored in a field study conducted on sunflowers grown from seeds treated with the systemic neonicotinoids thiamethoxam or clothianidin. This field trial was carried out in different representative growing areas in Spain over a beekeeping season. The health and development of the colonies was assessed by measuring factors that have a significant influence on their strength and overwintering ability. The parameters assessed were: colony strength (adult bees), brood development, amount of pollen and honey stores and presence and status of the queen. The concentration of residues (clothianidin and thiamethoxam) in samples of beebread and in adult bees was at the level of ng.g 1; in the ranges of 0.10-2.89 ng g-1 and 0.05-0.12 ng g-1; 0.10-0.37 ng g-1 and 0.01-0.05 ng g-1, respectively. Multivariate models were applied to evaluate the interaction among factors. No significant differences were found between the honeybee colonies of the different treatment groups, either exposed or not to the neonicotinoids. The seasonal development of the colonies was affected by the environmental conditions which, together with the initial strength of the bee colonies and the characteristics of the plots, had a significant effect on the different variables studied. PMID- 29597179 TI - Investigation of applicability of Electro-Fenton method for the mineralization of naphthol blue black in water. AB - In this study, mineralization and color removal performance of electro-Fenton method were examined in water containing naphthol blue black (NBB), a diazo dye. NBB was totally converted to intermediate species in a 15-min electrolysis at 60 mA, but complete de-colorization took 180 min. A very high oxidation rate constant ((3.35 +/- 0.21) x 1010 M-1s-1) was obtained for NBB, showing its high reactivity towards hydroxyl radicals. A very high total organic carbon (TOC) removal value (45.23 mg L-1) was obtained in the first 60 min of the electro Fenton treatment of an aqueous solution of NBB (0.25 mM) at 300 mA, indicating the mineralization efficiency of the electro-Fenton method. Mineralization current efficiency values obtained at 300 mA gradually decreased from 24.18% to 4.47% with the electrolysis time, indicating the presence of highly parasitic reactions. Gas chromatography-mass spectrometry analyses revealed that the cleavage of azo bonds of NBB led to formation of different aromatic and aliphatic oxidation intermediates. Ion chromatography analysis showed that ammonium, nitrate and sulfate were the mineralization end-products. The concentration of sulfate ion reached to its quantitative value at the 4th h of electrolysis. On the other hand, the total concentration of ammonium and nitrate ions reached to only 61% of the stoichiometric amount of initial nitrogen after a 7 h electrolysis. Finally, it can be said that the electro-Fenton method is a suitable and efficient method for the removal of NBB and its intermediates from water. PMID- 29597180 TI - Leakage of soluble microbial products from biological activated carbon filtration in drinking water treatment plants and its influence on health risks. AB - The application of ozone-biological activated carbon (O3-BAC) as an advanced treatment method in drinking water treatment plants (DWTPs) can help to remove organic micropollutants and further decrease the dissolved organic carbon (DOC) level in finished water. With the increase attention to microbial safety of drinking water, a pre-positioned O3-BAC followed by a sand filter has been implanted into DWTP located in Shanghai, China to increase the biostability of effluents. The results showed that BAC had high removal efficiencies of UV254, DOC and disinfection by-product formation potential (DBPFP). The removal efficiencies between pre- and post-positioned BAC filtrations were similar. Based on the analyses of fluorescence excitation-emission matrix spectrophotometry (FEEM), the generation and leakage of soluble microbial products (SMPs) were found in both two BAC filtrations on account of the increased fluorescence intensities and fluorescence regional integration (FRI) distribution of protein like organics, as well as the enhanced biological index (BIX). The leakage of SMPs produced by metabolism of microbes during BAC process resulted in increased DBPFP yield and carcinogenic factor per unit of DOC (CF/DOC). Although BAC filtration reduced the DBPFP and CF, there still was high health risk of effluents for the production of SMPs. Therefore, the health risks for SMPs generated by BAC filtration in drinking water advanced treatment process should be addressed, especially with that at high temperature.

Ivermectin residues are excreted in dung, threatening non-target coprophagous fauna such as dung beetles. This can have severe ecological and economic consequences for dung degradation and soil fertility. Even though the negative effects of direct ivermectin exposure on dung-degrading organisms are well known, effects could extend across generations. Here, we tested the effects of paternal or maternal exposure to ivermectin on offspring in the dung beetle Euoniticellus intermedius. This species is a classic study subject in ecotoxicology and sexual selection because males have a cephalic horn that is under intense selection via male-male competition. After confirming a negative effect of ivermectin on the number of emerged beetles, we found trans-generational effects of ivermectin exposure on the horn size of male offspring. Surprisingly however, this trans-generational effect only occurred when only the father was exposed. We detected no trans generational effects of ivermectin exposure on offspring number, sex ratio or body size. Our results confirm that ivermectin not only has a strong effect on exposed individuals but also in their progeny. Our study opens new questions about the mechanisms responsible for parental effects and their long-term fitness consequences in contaminated habitats. PMID- 29597182 TI - Potential electron donor for nanoiron supported hydrogenotrophic denitrification: H2 gas, Fe0, ferrous oxides, Fe2+(aq), or Fe2+(ad)? AB - The mechanism of electron transmission in combined nanoiron-bacteria denitrification cannot be explained by the classic model, in which an Fe0H2 nitrate transferring chain is proposed. In this study, we used characteristic techniques and electrochemical analysis to investigate the necessity of molecular hydrogen for the combined denitrifying system using commercial nanoiron with Alcaligenes eutrophus, and to analyze its potential electron donor. Based on our results, nitrate removal and its by-products (NO2- and NH4+) generation was not significantly affected by residual H2 gas, indicating that H2 was not necessary for hydrogenotrophic denitrification. As to the potential electron donor analysis, nanoscale zero-valent iron did not appear to be the electron donor due to its high level of toxicity (83% mortality using nanoiron versus 36% in the control cells). In addition, when iron oxides (Fe3O4, Fe2O3 and FeOOH on the nanoiron surface) and free ferrous ions [Fe2+(aq)] were present alone, they were not utilized by the bacteria to degrade nitrate. According to the results of electrochemical analysis, adsorbed ferrous iron [Fe2+(ad)] on ferric oxides might be the electron donor in this kind of nitrate removal. PMID- 29597183 TI - Quantitative measurements in single-cell analysis: towards scalability in microbial bioprocess development. AB - Single-cell analysis in microfluidic cultivation devices bears a great potential for the development and optimization of industrial bioprocesses. High parallelization allows running a large number of cultivation experiments simultaneously even under quick alteration of environmental conditions. For example, the impact of changes in media composition on cell growth during classical batch cultivation can be easily resolved. A missing link for the scalability of microfluidic experiments is, however, their complete characterization via conventional performance indicators such as product titer and productivity. While existing mass spectrometry technology is not yet sufficiently coupled with microfluidics, optical methods like enzymatic assays or fluorescence sensors are promising alternatives but require further improvement to generate quantitative measurements of extracellular metabolites. PMID- 29597184 TI - Global exponential synchronization of inertial memristive neural networks with time-varying delay via nonlinear controller. AB - The paper is concerned with the synchronization problem of inertial memristive neural networks with time-varying delay. First, by choosing a proper variable substitution, inertial memristive neural networks described by second-order differential equations can be transformed into first-order differential equations. Then, a novel controller with a linear diffusive term and discontinuous sign term is designed. By using the controller, the sufficient conditions for assuring the global exponential synchronization of the derive and response neural networks are derived based on Lyapunov stability theory and some inequality techniques. Finally, several numerical simulations are provided to substantiate the effectiveness of the theoretical results. PMID- 29597185 TI - Diazepam for outpatient treatment of nonconvulsive status epilepticus in pediatric patients with Angelman syndrome. AB - Nonconvulsive status epilepticus (NCSE) is present in multiple pediatric neurogenetic syndromes with epileptic encephalopathies. While intravenous (IV) medications are used inpatient for treatment of critical illness-related NCSE, there is no consensus on treatment of ambulatory NCSE. Up to 50% of patients with Angelman syndrome (AS) have NCSE with myoclonic or atypical absence status. Here we report our experience in pediatric patients with AS and NCSE treated outpatient with a tapering course of oral diazepam. We conducted a chart review of 104 patients seen in the Angelman Syndrome Clinic at Massachusetts General Hospital from January 2008 to March 2017, who met the criteria. Response to treatment was defined as cessation of NCSE symptoms with electroencephalogram (EEG) confirmation when possible. Twenty-one patients with NCSE were identified, and 13 patients (9 male) with 25 episodes of NCSE were included. Mean age at NCSE episode was 5years 4months (15months-12years). Six patients had one episode of NCSE, and 7 patients had recurrent episodes (mean: 2.7; range: 2-4). Median diazepam treatment was 6days (4-12days), with a mean dose of 0.32mg/kg/day divided over 2-3 administrations, decreased every 2days. Nine episodes required multiple courses; however, oral diazepam alone was ultimately successful in 80% (20/25) of NCSE episodes. Oral diazepam was well-tolerated with no major side effects. A short course of oral diazepam is well-tolerated and effective in patients with AS who have ambulatory NCSE. It may be considered prior to escalating to inpatient care in AS and possibly other epilepsy syndromes. PMID- 29597186 TI - Levels of Endocan, Angiopoietin-2, and Hypoxia-Inducible Factor-1a in Patients with Autosomal Dominant Polycystic Kidney Disease and Different Levels of Renal Function. AB - BACKGROUND: Endothelial dysfunction leading to unbalanced vasoconstriction and ischemia of renal parenchyma is increasingly proposed as an alternative pathway of renal damage in autosomal dominant polycystic kidney disease (ADPKD). However, human studies investigating the evolution of such phenomena are limited. This study investigated the levels of emerging biomarkers of endothelial function, angiogenesis and hypoxia, in ADPKD patients with different renal function. METHODS: The study population consisted of three groups: 26 ADPKD patients with impaired renal function (Group A; estimated glomerular filtration rate [eGFR] 45 70 mL/min/1.73 m2), 26 ADPKD patients with preserved renal function (Group B; eGFR >70 mL/min/1.73 m2), and 26 age- and sex-matched controls with no history of renal disease. Circulating levels of endocan (endothelial cell-specific molecule 1) angiopoietin-2, and hypoxia-inducible factor-1a (HIF-1a) were determined by enzyme-linked immunosorbent assay techniques. RESULTS: Patients in Group A had significantly higher levels of endocan (7.17 +/- 0.43 ng/mL), angiopoietin-2 (5,595.43 +/- 3,390), and HIF-1a (163.68 +/- 37.84 pg/mL) compared to patients in Group B (6.86 +/- 0.59 ng/mL, p = 0.017, 3,854.41 +/- 3,014.30, p = 0.018, 136.84 +/- 42.10 pg/mL, p = 0.019 respectively) or controls (4.83 +/- 0.69 ng/mL, 1,069 +/- 427.88 pg/mL, 70.20 +/- 17.49 pg/mL, p < 0.001 for all comparisons). Of note, patients in Group B had also higher levels of all markers compared to controls (p < 0.001) despite having similar renal function. In correlation analyses within ADPKD patients, we noted strong correlations of all studied markers with asymmetric dimethylarginine (ADMA; endocan r = 0.908, p < 0.001, angiopoietin-2 r = 0.983, p < 0.001 and HIF-1a r = 0.998, p < 0.001), and only weak or modest correlations with eGFR. CONCLUSIONS: This study suggests that endothelial dysfunction causing microcirculatory changes, linked to angiogenesis and hypoxia, may come early in the course of ADPKD and could be a key regulator of renal injury progression.

AB - BACKGROUND: There is a paucity of data on the spectrum of renal diseases prevalent in the Jammu and Kashmir region. OBJECTIVES: To determine the spectrum of glomerulopathies in adult patients attending a tertiary care centre. METHODS: Two hundred and twenty-one adequate biopsies from native kidneys of adult patients who presented with features suggestive of glomerular diseases at Sheri Kashmir Institute of medical sciences Srinagar Kashmir for the last 8 years were studied in a retrospective manner. Light and immunofluorescence (IF) microscopy were performed to evaluate these biopsies after obtaining well-informed consent from each patient. RESULTS: Of the 221 biopsies carried out, 150 were performed on males and 71 on females with the mean age of 29 +/- 13.5 years. The main presentation was the nephrotic syndrome in 177 (80%), hypertension in 60 (27%), renal insufficiency in 48 (21.7%), and abnormal urinary sediment in 42 (20.3%) of patients. The histopathology revealed minimal change disease (MCD) in 69 (31.2%), membranous glomerulonephritis (MGN) in 48 (21.7%), focal segmental glomerulsclerosis (FSG) in 49 (18%), and mesangioproliferative glomerulonephritis in 16 (7.2%). Patients with atypical presentation of diabetes mellitus showed diabetic nephropathy in 12 (5.4%) patients. Lupus nephritis was in 5 (2.2%) patients. Majority of the patients with MPGN had Immunoglobulin A deposits on IF. While evaluating the underlying cause of MGN, only 1 patient, a 62-year-old male, proved to have adenocarcinoma of the stomach. In the remaining patients, no secondary cause could be found. Thrombotic complications seen in our study were deep venous thrombosis, renal vein thrombosis and middle cerebral artery thrombosis. CONCLUSION: MCD and MGN were the most common primary glomerular diseases observed in our centre. PMID- 29597190 TI - Vitamin B12 Deficiency and the Role of Gender: A Cross-Sectional Study of a Large Cohort. AB - BACKGROUND: Vitamin B12 deficiency is associated with hematological, neurological, and cardiovascular consequences. Epidemiologic data on these related illnesses indicate gender differences. METHODS: A cross-sectional study was designed to examine gender differences in vitamin B12 deficiency among a healthy population. Data from healthy individuals aged 18-65, who were provided with a routine medical evaluation during 2000-2014, were retrieved from the medical charts. Individuals with background illnesses and those who had used medications or nutritional supplements were excluded. Vitamin B12 deficiency was defined by 2 cutoff values (206 and 140 pmol/L). The multivariate analysis was adjusted for age, body mass index, estimated glomerular filtration rate, hyperhomocysteinemia, folate deficiency, albumin, and transferrin saturation. Sensitivity analyses were implemented by excluding individuals with anemia, hyperhomocysteinemia, or folate deficiency and by age stratification. RESULTS: In all, 7,963 individuals met the inclusion criteria. Serum vitamin B12 mean levels were 312.36 and 284.31 pmol/L for women and men respectively (p < 0.001). Deficiency prevalence was greater for men (25.5%) in comparison with women (18.9%; p < 0.001). Men were strongly associated with severe deficiency (adjusted OR 2.26; 95% CI 1.43-3.56). CONCLUSIONS: Among the healthy population, men are susceptible to vitamin B12 deficiency. This can be explained by neither diet habits nor estrogen effects. Genetic variations are therefore hypothesized to play a role. PMID- 29597191 TI - Arkadia (RING Finger Protein 111) Mediates Sumoylation-Dependent Stabilization of Nrf2 Through K48-Linked Ubiquitination. AB - BACKGROUND/AIMS: The transcription factor Nrf2 is a master regulator of the antioxidant defense system, protecting cells from oxidative damage. We previously reported that the SUMO-targeted E3 ubiquitin ligase (STUbL), RING finger protein 4 (RNF4) accelerated the degradation rate of Nrf2 in promyelocytic leukemia nuclear body (PML-NB)-enriched fractions and decreased Nrf2-mediated gene transcription. The mechanisms that regulate Nrf2 nuclear levels are poorly understood. In this study, we aim to explore the role of the second mammalian STUbL, Arkadia/RNF111 on Nrf2. METHODS: Arkadia mediated ubiquitination was detected using co-immunoprecipitation assays in which whole cell lysates were immunoprecipated with anti-Nrf2 antibody and Western blotted with anti hemagglutinin (HA) antibody or anti-Lys-48 ubiquitin-specific antibody. The half life of Nrf2 was detected in whole cell lysates and promyelocytic leukemia nuclear body enriched fractions by cycloheximide-chase. Reporter gene assays were performed using the antioxidant response element (ARE)-containing promoter Heme oxygenase-1 (HO-1). RESULTS: We show that Arkadia/RNF111 is able to ubiquitinate Nrf2 resulting in the stabilization of Nrf2. This stabilization was mediated through Lys-48 ubiquitin chains, contrary to traditionally degradative role of Lys-48 ubiquitination, suggesting that Lys-48 ubiquitination of Nrf2 protects Nrf2 from degradation thereby allowing Nrf2-dependent gene transcription. CONCLUSION: Collectively, these findings highlight a novel mechanism to positively regulate nuclear Nrf2 levels in response to oxidative stress through Arkadia-mediated K48-linked ubiquitination of Nrf2. PMID- 29597192 TI - Transcatheter Closure of Patent Foramen Ovale versus Medical Therapy after Cryptogenic Stroke: A Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND: Patent foramen ovale (PFO) with atrial septal aneurysm is suggested as an important potential source for cryptogenic strokes. Percutaneous PFO closure to reduce the recurrence of stroke compared to medical therapy has been intensely debated. The aim of this study is to assess whether PFO closure in patients with cryptogenic stroke is safe and effective compared with medical therapy. METHOD: A search of PubMed, Medline, and Cochrane Central Register from January 2000 through September 2017 for randomized controlled trails (RCT), which compared PFO closure to medical therapy in patients with cryptogenic stroke was conducted. We used the items "PFO or patent foramen ovale", "paradoxical embolism", "PFO closure" and "stroke". Data were pooled for the primary outcome measure using the random-effects model as pooled rate ratio (RR). The primary outcome was reduction in recurrent strokes. RESULT: Among 282 studies, 5 were selected. Our analysis included 3,440 patients (mean age 45 years, 55% men, mean follow-up 2.9 years), 1,829 in the PFO closure group and 1,611 in the medical therapy group. The I2 heterogeneity test was found to be 48%. A random effects model combining the results of the included studies demonstrated a statistically significant risk reduction in risk of recurrent stroke in the PFO closure group when compared with medical therapy (RR 0.42; 95% CI 0.20-0.91, p = 0.03). CONCLUSION: Pooled data from 5 large RCTs showed that PFO closure in patients with cryptogenic stroke is safe and effective intervention for prevention of stroke recurrence compared with medical therapy. PMID- 29597193 TI - Zika virus Pathogenesis in Infant Mice after Natural Transmission by the Bite of Infected Mosquitoes. AB - OBJECTIVES: The objective of this study was to understand natural disease progression in infant CD1 mice after the bite of Aedes aegypti mosquitoes infected by the Zika virus (ZIKV, MR-766 strain). METHODS: A. aegypti mosquitoes were experimentally infected with ZIKV MR-766 strain via the oral feeding route. Infected mosquitoes were allowed to feed on infant CD1 mice. Sick mice were euthanized, and their organs were collected and subjected to real-time RT-PCR, histo-pathology, and immunohistochemistry. RESULTS: Clinical symptoms appeared in mice after 4-5 days of being bitten by mosquitoes, following which they were euthanized. Real-time RT-PCR analysis showed the presence of viral RNA in various organs such as the brain, liver, kidney, spleen, lungs, and intestines of the mice. The brain tissue specimens showed higher viral loads as determined by threshold values (Ct value) in the real-time RT-PCR assay. Histopathological and immunohistochemistry studies also revealed the presence of the virus and associated lesions in the brain, indicating that ZIKV shows tropism for neuronal tissue. CONCLUSIONS: This study demonstrates ZIKV pathogenesis in infant CD1 mice and that these mice are highly susceptible to natural infection with this ZIKV strain.

PMID- 29597194 TI - FcgammaRIIIA Negatively Impacts Humoral Immune Responses but Not Overall Lung Inflammation in an Ovalbumin-Induced Allergic Asthma Mouse Model. AB - BACKGROUND: Fcgamma receptors (FcgammaR) play substantial immune regulatory roles both positively and negatively in pathophysiological processes including allergy and asthma. Compared with FcgammaRIIB which is classically defined as an inhibitory receptor, mouse FcgammaRIIIA and its functional human homologue FcgammaRIIA have been assumed to be activating receptors. However, evidence demonstrating inhibitory regulation by mouse FcgammaRIIIA has recently been emerging. OBJECTIVE: To dissect the contributory roles of mouse FcgammaRIIIA (human FcgammaRIIA) in parallel with FcgammaRIIB in an ovalbumin (OVA)-induced mouse model of asthma and to preliminarily assess the correlation of the respective FcgammaR with circulating IgE levels in human asthma patients. METHODS: Wild-type, FcgammaRIIB-/-, and FcgammaRIIIA-/- mice were used in an OVA induced asthma model followed by assessment of the allergic pathology focused on the lung tissues. Expression levels of FcgammaRIIB, FcgammaRIIA, and FcgammaRIIIA on peripheral blood mononuclear cells (PBMC) together with the circulating IgE levels in the serum from patients with allergic asthma were analysed. RESULTS: Although enhanced humoral immune responses typically represented by augmented OVA specific IgG and IgE levels in serum were observed in the absence of FcgammaRIIIA in the mouse asthma model, no overall regulation by FcgammaRIIIA, especially in terms of those parameters measuring lung tissue inflammation, was recorded. As expected, in the absence of FcgammaRIIB, augmented immune responses measured as serum antibody levels as well as those in various regulatory pathways in this mouse asthma model were observed. The expression levels of human FcgammaRIIB but not FcgammaRIIA were negatively correlated with serum levels of IgE in human asthma patients. CONCLUSION: We did not find major evidence demonstrating an immune inhibitory role of mouse FcgammaRIIIA in this OVA-induced mouse asthma model. As asthma is a complex disease and the immune regulatory responses involve sophisticated components and pathways, the exact roles of FcgammaRIIIA as well as its human functional homologue FcgammaRIIA in asthma still await further clarification using other mouse asthma models as well as clinical studies. PMID- 29597196 TI - Dermocosmetics for Use in Rosacea: Guideline of the Society for Dermopharmacy. AB - Rosacea is a widespread inflammatory skin disease that is chronically recurrent and affects predominately the central parts of the face. Affected individuals typically react to numerous cosmetics with redness, burning, and/or worsening of the complexion. Consequently, there is a high demand for dermocosmetics that do not provoke such reactions and are suitable for use in rosacea. The present guideline of the Society for Dermopharmacy describes the requirements that dermocosmetics for use in rosacea should meet. They include, inter alia, methods to prove the efficacy of and tolerance to these cosmetics, as well as the product documentation that the manufacturer or the distributing company should make available to professionals, like dermatologists and pharmacists, counseling patients with rosacea. PMID- 29597198 TI - Exercise-Induced Change in Plasma IL-12p70 Is Linked to Migraine Prevention and Anxiolytic Effects in Treatment-Naive Women: A Randomized Controlled Trial. AB - OBJECTIVE: To conduct a randomized controlled trial to evaluate the effect of a 12-week aerobic exercise program for migraine prevention, plasma cytokines concentrations (TNF-alpha, interleukin [IL]-1beta, IL-6, IL-8, IL-10, and IL 12p70), and anxiety in women with migraine. METHODS: Women with episodic migraine (ICHD-II), aged between 20 and 50 years, who had never taken any prophylactic medication, and were physically inactive in the past 12 months were recruited from the university's hospital and a tertiary headache clinic between March 2012 and March 2015. Migraine attacks were recorded in headache diaries, cytokines were quantified by flow cytometry, and anxiety was assessed by the 7-item General Anxiety Disorder (GAD-7) scale. Blood sampling and psychometric interviews were undertaken on headache-free days. RESULTS: Twenty participants ([mean +/- SD] age 33.8 +/- 10.5; BMI 26 +/- 5.2) were randomly assigned and received intervention ("trained": n = 10) or entered on a waitlist ("inactive": n = 10). There were no differences between groups regarding patients' characteristics and baseline data. Days with migraine (p = 0.001), IL-12p70 levels (p = 0.036), and GAD-7 score (p = 0.034) were significantly reduced in the trained group after the intervention period, but there were no significant changes in these variables in the inactive group. There was no change in the levels of the other cytokines in either group. There were positive correlations between a reduction in IL-12p70 level and a reduction in the number of days with migraine (R2 = 0.19, p = 0.045), and GAD-7 score (R2 = 0.53, p < 0.001). CONCLUSION: The clinical and psychological therapeutic effects of aerobic exercise in treatment-naive women with migraine may involve the downregulation of IL-12p70. PMID- 29597197 TI - Brain Activation Patterns in Response to Conspecific and Heterospecific Social Acoustic Signals in Female Plainfin Midshipman Fish, Porichthys notatus. AB - While the peripheral auditory system of fish has been well studied, less is known about how the fish's brain and central auditory system process complex social acoustic signals. The plainfin midshipman fish, Porichthys notatus, has become a good species for investigating the neural basis of acoustic communication because the production and reception of acoustic signals is paramount for this species' reproductive success. Nesting males produce long-duration advertisement calls that females detect and localize among the noise in the intertidal zone to successfully find mates and spawn. How female midshipman are able to discriminate male advertisement calls from environmental noise and other acoustic stimuli is unknown. Using the immediate early gene product cFos as a marker for neural activity, we quantified neural activation of the ascending auditory pathway in female midshipman exposed to conspecific advertisement calls, heterospecific white seabass calls, or ambient environment noise. We hypothesized that auditory hindbrain nuclei would be activated by general acoustic stimuli (ambient noise and other biotic acoustic stimuli) whereas auditory neurons in the midbrain and forebrain would be selectively activated by conspecific advertisement calls. We show that neural activation in two regions of the auditory hindbrain, i.e., the rostral intermediate division of the descending octaval nucleus and the ventral division of the secondary octaval nucleus, did not differ via cFos immunoreactive (cFos-ir) activity when exposed to different acoustic stimuli. In contrast, female midshipman exposed to conspecific advertisement calls showed greater cFos ir in the nucleus centralis of the midbrain torus semicircularis compared to fish exposed only to ambient noise. No difference in cFos-ir was observed in the torus semicircularis of animals exposed to conspecific versus heterospecific calls. However, cFos-ir was greater in two forebrain structures that receive auditory input, i.e., the central posterior nucleus of the thalamus and the anterior tuberal hypothalamus, when exposed to conspecific calls versus either ambient noise or heterospecific calls. Our results suggest that higher-order neurons in the female midshipman midbrain torus semicircularis, thalamic central posterior nucleus, and hypothalamic anterior tuberal nucleus may be necessary for the discrimination of complex social acoustic signals. Furthermore, neurons in the central posterior and anterior tuberal nuclei are differentially activated by exposure to conspecific versus other acoustic stimuli.

PMID- 29597200 TI - Acute Treatment with T-Type Calcium Channel Enhancer SAK3 Reduces Cognitive Impairments Caused by Methimazole-Induced Hypothyroidism Via Activation of Cholinergic Signaling. AB - Hypothyroidism is a common disorder that is associated with psychological disturbances such as dementia, depression, and psychomotor disorders. We recently found that chronic treatment with the T-type calcium channel enhancer SAK3 prevents the cholinergic neurodegeneration induced by a single intraperitoneal (i.p.) injection of methimazole (MMI; 75 mg/kg), thereby improving cognition. Here, we evaluated the acute effect of SAK3 on cognitive impairments and its mechanism of action following the induction of hypothyroidism. Hypothyroidism was induced by 2 injections of MMI (75 mg/kg, i.p.) administered once per week. Four weeks after the final MMI treatment, MMI-treated mice showed reduced serum thyroxine (T4) levels and cognitive impairments without depression-like behaviors. Although acute SAK3 (1.0 mg/kg, p.o.) administration failed to ameliorate the decreased T4 levels and histochemical destruction of the glomerular structure, acute SAK3 (1.0 mg/kg, p.o.) administration significantly reduced cognitive impairments in MMI-treated mice. Importantly, the alpha7 nicotinic acetylcholine receptor (nAChR)-selective inhibitor methyllycaconitine (MLA; 12 mg/kg, i.p.) and T-type calcium channel-specific blocker NNC 55-0396 (25 mg/kg, i.p.) antagonized the acute effect of SAK3 on memory deficits in MMI treated mice. We also confirmed that acute SAK3 administration does not rescue reduced olfactory marker protein or choline acetyltransferase immunoreactivity levels in the olfactory bulb or medial septum. Taken together, these results suggest that SAK3 has the ability to improve the cognitive decline caused by hypothyroidism directly through activation of nAChR signaling and T-type calcium channels. PMID- 29597201 TI - Robert Wartenberg, MD (1887-1956). AB - Modern technologies have, to some degree, replaced the careful elicitation of neurological physical signs. Many 20th century texts and monographs were devoted to such clinical phenomena. Foremost among them were the assiduous writings of Robert Wartenberg who fled Hitler to enhance Neurology in San Francisco. His work and influences are outlined here. PMID- 29597202 TI - Impact of Implementing 100% Rapid Review as a Quality Control Tool in Cervical Cytology. AB - OBJECTIVE: We aimed to evaluate the impact of implementing 100% rapid review (100% RR) as a quality control tool in cervical smear cytology. DESIGN: A cross sectional study was conducted in which cytology findings, false-negative results, and quality indicators were evaluated. The variables were analyzed in 2004, the year in which 100% RR was implemented, and again in 2013, i.e., 10 years on. RESULTS: Detection of atypical squamous cells of undetermined significance (ASC US) increased from 0.90% in 2004 to 2.47% in 2013 by routine screening. Detection of atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion (ASC-H) increased from 13.33% in 2004 to 36.27% in 2013 by 100% RR. Detection of high-grade squamous intraepithelial lesion (HSIL) increased from 0.64% in 2004 to 4.29% in 2013 by routine screening, and increased from 0% in 2004 to 19.61% in 2013 by 100% RR. There was a significant increase (p = 0.00001) in the identification of false-negative results of ASC-US, low-grade squamous intraepithelial lesion, ASC-H, HSIL, and atypical glandular cells. All quality indicators had increased in 2013 when compared to 2004 results. CONCLUSIONS: Ten years after the implementation of the 100% RR method, improvements were found in the detection of atypia and precursor lesions and in quality indicators. PMID- 29597203 TI - Identification of Cytological Features Distinguishing Mucosa-Associated Lymphoid Tissue Lymphoma from Reactive Lymphoid Proliferation Using Thyroid Liquid-Based Cytology. AB - OBJECTIVE: To identify cytological differences between mucosa-associated lymphoid tissue lymphoma (MALT-L) and nonneoplastic lymphocytes using thyroid liquid-based cytology (LBC). STUDY DESIGN: We observed LBC and conventional specimens from 35 MALT-L cases, 3 diffuse large B-cell cell lymphoma (DLBCL) cases, and 44 prominent nonneoplastic lymphocytic infiltration cases. RESULTS: In MALT-L cases, the incidence of lymphoglandular bodies in the LBC specimens was lower than that in the conventional specimens (p < 0.001). Moreover, the nuclear sizes in LBC specimens were larger than those in conventional specimens. In 62.9% of the MALT L and all DLBCL specimens, large nuclei were present in > 10% of the lymphoid cells in LBC specimens. Two cases with prominent nonneoplastic lymphocytic infiltration also exhibited these findings. In LBC specimens, swollen naked nuclei with less punctate chromatin patterns and thin nuclear margins were observed in 92.1% of lymphoma and 20.5% of prominent nonneoplastic lymphocytic infiltration. Elongated nuclei were significantly more apparent in thyroid lymphoma than in prominent nonneoplastic lymphocytic infiltration (p < 0.001), with a significantly higher incidence in LBC specimens than in conventional specimens (p < 0.001). CONCLUSIONS: Lymphoglandular bodies are not reliable markers for lymphoma diagnosis using LBC specimens. Large, swollen naked, and elongated nuclei are useful in distinguishing thyroid lymphoma from nonneoplastic lymphocytes in LBC specimens. PMID- 29597204 TI - Subjective Social Status Predicts Late-Life Memory Trajectories through Both Mental and Physical Health Pathways. AB - BACKGROUND: Subjective social status (SSS) is associated with mental and physical health, independent of objective socioeconomic status (SES), but its association with late-life cognitive decline is unknown. OBJECTIVE: This study characterizes the association between SSS and late-life memory trajectories in a large, nationally representative sample of older adults in the United States. METHODS: Using data from 8,530 participants aged 65 years and older in the Health and Retirement Study, structural equation models tested associations between SSS, objective SES (i.e., educational attainment, occupation, income, and wealth), physical and mental health, and 6-year memory trajectories, controlling for sociodemographic characteristics. RESULTS: Independent of objective SES, lower SSS was associated with worse initial memory but not subsequent memory decline. The association between SSS and initial memory was separately mediated by chronic diseases, stroke, and depressive symptoms. CONCLUSION: Results provide preliminary behavioral evidence for the deleterious effects of social stress on cognitive aging. These results may help inform the development of policies and interventions to reduce cognitive morbidity among older adults who perceive a low position on the social hierarchy. PMID- 29597205 TI - Prevalence of Overweight and Obesity in Hungarian Children and Adolescents. AB - BACKGROUND/AIMS: The prevalence of overweight and obesity in children and adolescents is increasing worldwide, and this condition is a risk factor for cardiovascular mortality. The aim of this study was to assess the prevalence of overweight and obesity among the 3-18-year-old population in Szolnok City and the surrounding areas. METHODS: Anthropometric data from healthy, white individuals recruited from nursery, elementary, and secondary schools were used to assess the prevalence of obesity and overweight in Szolnok City and the surrounding area, Jasz-Nagykun-Szolnok county, Hungary. Healthy subjects numbering 6,824 (54% boys) were included; overweight and obesity were defined according to the relevant guidelines. RESULTS: Overweight individuals constituted 13.4% of the population and 6.6% were obese. The total prevalence was higher in boys (21.6%) than in girls (18.1%). The peak of the prevalence was observed at age 10 in both sexes (boys 33%, girls 27%) followed by a gradual decrease, which was more significant in the case of girls. CONCLUSIONS: On the basis of the recent Hungarian data, we have not detected any changes in overweight and obesity in the age group 3-9 years and we have found a significant decrease in the age group 7-14 years. Prevention of overweight and obesity in early childhood is essential.

PMID- 29597206 TI - Curcumin Alleviates Diabetic Retinopathy in Experimental Diabetic Rats. AB - PURPOSE: To investigate the potential protective effects of curcumin on the retina in diabetic rats. METHODS: An experimental diabetic rat model was induced by a low dose of streptozotocin combined with a high-energy diet. Rats which had blood glucose levels >=11.6 mmol/L were used as diabetic rats. The diabetic rats were randomly divided into 3 groups: diabetic rats with no treatment (DM), diabetic rats treated with 100 mg/kg curcumin (DM + Cur 100 mg/kg), and diabetic rats treated with 200 mg/kg curcumin (DM + Cur 200 mg/kg). Curcumin was orally administered daily for 16 weeks. After 16 weeks of administration, the rats were euthanized, and eyes were dissected. Retinal histology was examined, and the thickness of the retina was measured. Ultrastructural changes of retinal ganglion cells, inner layer cells, retinal capillary, and membranous disks were observed by electron microscopy. Malondialdehyde, superoxide dismutase, and total antioxidant capacity were measured by ELISA. Expression levels of vascular endothelial growth factor (VEGF) in retina tissues were examined by immunohistochemical staining and ELISA. Expression levels of Bax and Bcl-2 in retina tissues were determined by immunohistochemical staining and Western blotting. RESULTS: Curcumin reduced the blood glucose levels of diabetic rats and decreased diabetes-induced body weight loss. Curcumin prevented attenuation of the retina in diabetic rats and ameliorated diabetes-induced ultrastructure changes of the retina, including thinning of the retina, apoptosis of the retinal ganglion cells and inner nuclear layer cells, thickening of retinal capillary basement membrane and disturbance of photoreceptor cell membranous disks. We also found that curcumin has a strong antioxidative ability in the retina of diabetic rats. It was observed that curcumin attenuated the expression of VEGF in the retina of diabetic rats. We also discovered that curcumin had an antiapoptotic effect by upregulating the expression of Bcl-2 and downregulating the expression of Bax in the retina of diabetic rats. CONCLUSIONS: Taken together, these results suggest that curcumin may have great therapeutic potential in the treatment of diabetic retinopathy which could be attributed to the hypoglycemic, antioxidant, VEGF-downregulating and neuroprotection properties of curcumin. PMID- 29597209 TI - Feasibility of "Watch-and-Wait" Management before Repeat Hepatectomy for Colorectal Liver Metastases. AB - BACKGROUND: Whether repeat hepatectomy for colorectal liver metastases should be performed after chemotherapy or observation is unclear. METHODS: We selected patients with resectable hepatic recurrence after their first hepatectomies performed between 2000 and 2015. They were classified according to the further treatment: Group A, prompt repeat hepatectomy; Group B, observation; and Group C, <=6 months of chemotherapy. In Group B/C, patients who later underwent hepatectomy and those who did not due to disease progression were classified as B1/C1 and B2/C2, respectively. Predictors of B2/C2 were evaluated. RESULTS: Groups A, B, and C consisted of 81, 36, and 17 patients, respectively. Recurrence free interval was longer in Group A (median months; Group A, 10.3; Group B, 5.7; Group C, 3.5; p < 0.01). Group B1/C1 and B2/C2 included 34 and 19 patients, respectively. Five-year survival after recurrence of Group B1/C1 was 56%, which was comparable with Group A (56%, p = 0.77) and better than Group B2/C2 (0%, p < 0.01). Multivariate analysis showed synchronous colorectal liver metastases (OR 7.23) and recurrent hepatic tumor number (OR 4.04) were predictors of tumor progression. CONCLUSION: Selecting patients optimally either for prompt or delayed repeat hepatectomy following chemotherapy or observation is a feasible strategy. PMID- 29597210 TI - Euodia daniellii Hemsl. (Bee-Bee Tree) Oil Attenuates Palmitate-Induced Lipid Accumulation and Apoptosis in Hepatocytes. AB - Hepatic lipid accumulation and apoptosis is elevated in patients with non alcoholic steatohepatitis and is closely associated with severity. Saturated fatty acid palmitate stimulates lipid accumulation and apoptosis in hepatocytes. In the present study, we examined bee-bee tree oil (BO)-mediated protective effects on palmitate-induced lipid accumulation and apoptosis in mouse primary hepatocytes. Cells were cultured in a control media or the same media containing 150 or 300 umol/L of albumin-bound palmitate for 24 h. BO concentrations used were 0, 0.1, 0.2, or 0.5%. Palmitate induced lipid accumulation and mRNA expression of lipogenic genes such as SREBP1c and SCD1. However, BO prevented these changes. Furthermore, palmitate stimulated caspase-3 activity and decreased cell viability in the absence of BO. BO reduced palmitate-induced activation of caspase-3 and cell death in a dose-dependent manner. AMP-activated protein kinase inhibitors abolished the effects of BO. Furthermore, BO suppressed palmitate induced c-Jun N-terminal kinase (JNK) phosphorylation through the 5' adenosine monophosphate-activated protein kinase (AMPK)-dependent pathway. In conclusion, BO attenuated palmitate-induced hepatic steatosis and apoptosis through AMPK-mediated suppression of JNK signaling. These data suggest that BO is an important determinant of saturated fatty acid-induced lipid accumulation and apoptosis, and may be an effective therapeutic strategy for treatment of obesity mediated liver diseases. PMID- 29597211 TI - Associations between Pre-Admission Risk Scores and Two-Year Clinical Outcomes in Ischemic Stroke or Transient Ischemic Attack Patients with Non-Valvular Atrial Fibrillation. AB - BACKGROUND: We aimed to clarify associations between pre-admission risk scores (CHADS2, CHA2DS2-VASc, and HAS-BLED) and 2-year clinical outcomes in ischemic stroke or transient ischemic attack (TIA) patients with non-valvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry. METHODS: From 18 Japanese stroke centers, ischemic stroke or TIA patients with NVAF hospitalized within 7 days after onset were enrolled. Outcome measures were defined as death/disability (modified Rankin Scale score >=3) at 2 years, 2-year mortality, and ischemic or hemorrhagic events within 2 years. RESULTS: A total of 1,192 patients with NVAF (527 women; mean age, 78 +/- 10 years), including 1,141 ischemic stroke and 51 TIA, were analyzed. Rates of death/disability, mortality, and ischemic or hemorrhagic events increased significantly with increasing pre admission CHADS2 (p for trend <0.001 for death/disability and mortality, p for trend = 0.024 for events), CHA2DS2-VASc (p for trend <0.001 for all), and HAS BLED (p for trend = 0.004 for death/disability, p for trend <0.001 for mortality, p for trend = 0.024 for events) scores. Pre-admission CHADS2 (OR per 1 point, 1.52; 95% CI 1.35-1.71; p <0.001 for death/disability; hazard ratio (HR) per 1 point, 1.23; 95% CI 1.12-1.35; p <0.001 for mortality; HR per 1 point, 1.14; 95% CI 1.02-1.26; p = 0.016 for events), CHA2DS2-VASc (1.55, 1.41-1.72, p < 0.001; 1.21, 1.12-1.30, p < 0.001; 1.17, 1.07-1.27, p < 0.001; respectively), and HAS BLED (1.33, 1.17-1.52, p < 0.001; 1.23, 1.10-1.38, p < 0.001; 1.18, 1.05-1.34, p = 0.008; respectively) scores were independently associated with all outcome measures. CONCLUSIONS: In ischemic stroke or TIA patients with NVAF, all pre admission risk scores were independently associated with death/disability at 2 years and 2-year mortality, as well as ischemic or hemorrhagic events within 2 years. PMID- 29597212 TI - Isolated Renal Hydatid Cyst Misdiagnosed and Operated as a Cystic Renal Tumor. AB - OBJECTIVE: The aim of this work is the presentation of a case of isolated renal hydatid cyst with novel findings and an unusual surgical scenario. CLINICAL PRESENTATION AND INTERVENTION: A 54-year-old female patient presented with left loin pain and a palpable left renal mass. Imaging described a well-demarcated left renal cystic lesion with a double-layer wall. Radical nephrectomy was performed due to the possibility of malignancy. On retrograde revision, the double-layer wall represented the detached germinative membrane of a hydatid cyst that was confirmed by histopathology. CONCLUSION: Isolated renal hydatid cyst could be misinterpreted as a renal tumor. It should be considered in the differential diagnosis of renal cystic lesions. PMID- 29597213 TI - The Staining of Mast Cells: A Historical Overview. AB - The specificity of several staining methods for mast cells provides the pathologist with a useful means for the differential diagnosis of mast cell tumors. Mast cells stain metachromatically with toluidine blue with greater intensity in cells containing smaller granules. Most stains for mast cells rely on the cell's content of heparin, other glycosaminoglycans, and esterase. As an alternative to histochemical stains, different antibodies have been used to identify mast cells in humans. PMID- 29597214 TI - Evolution of Technology for Continuous Renal Replacement Therapy: Forty Years of Improvement. AB - Continuous arteriovenous hemofiltration (CAVH) was proposed in 1977 as an alternative treatment for acute renal failure in patients in whom peritoneal dialysis or hemodialysis was clinically or technically precluded. In the mid 1980s, this technique was extended to infants and children. CAVH presented important advantages in the areas of hemodynamic stability, control of circulating volume, and nutritional support. However, there were serious shortcomings such as the need for arterial cannulation and limited solute clearance. These problems were solved by the introduction of continuous arteriovenous hemodiafiltration and continuous arteriovenous hemodialysis, where uremic control could be achieved by increasing countercurrent dialysate flow rates to 1.5 or 2 L/h as necessary, or by venovenous techniques utilizing a double-lumen central venous catheter for vascular access. Thus, continuous venovenous hemofiltration replaced CAVH because of its improved performance and safety. From the initial adoptive technology, specific machines have been designed to permit safe and reliable performance of the therapy. These new machines have progressively undergone a series of technological steps that have resulted in the evolution of highly sophisticated equipment utilized today. A significant number of advances have taken place since the time continuous renal replacement therapy was initiated. In particular, there have been successful experiments with high-volume hemofiltration and high-permeability hemofiltration. The additional and combined use of sorbent has also been tested successfully. Progress has been made in the technology as well as the understanding of the pathophysiology of acute kidney injury. Today, new biomaterials and new devices are available and new frontiers are on the horizon. Although improvements have been made, a lot remains to be done. Critical care nephrology is expected to further evolve in the near future, especially in the area of information and communication technology, utilization of big data and large database registries, biofeedback, and assisted prescription and treatment delivery, with high potential for improvement in morbidity and mortality of the most severely ill patients. PMID- 29597215 TI - Evolution of Vascular Access and Anticoagulation. AB - Continuous renal replacement therapy (CRRT) is an important and widely used adjuvant treatment in critically ill patients. However, any CRRT protocol can be adhered to only when the technique is correctly installed and functioning properly. Within this context, an appropriate vascular access and a safe and effective circuit anticoagulation method are key requisites. The right internal jugular (RIJ) vein is the preferred route for insertion with the tip of the catheter placed in the right atrium. Both femoral veins offer a valuable alternative access, but catheters must be longer to avoid recirculation and circuit blood flow is lower as compared with that of the RIJ approach. The location of the catheter is not associated with differences in bacterial colonization/infection rate or filter/circuit lifespan. Adequate anticoagulation is imperative to avoid a system "shutdown" due to the early clotting of the filter. For a long time, unfractionated heparin (UFH) was the anticoagulant of choice. UFH is associated with an increased bleeding risk and requires the use of high circuit blood flows. The introduction of regional citrate anticoagulation (RCA) created a paradigm change in CRRT anticoagulation. RCA can be applied safely in patients with increased bleeding risk and may enhance filter and circuit survival as compared with UFH. RCA requires close monitoring for potentially serious metabolic side effects. Future perspectives include improved catheter technology and development of novel citrate solutions with less severe metabolic impact. PMID- 29597216 TI - Indications and Timing of Continuous Renal Replacement Therapy Application. AB - Renal replacement therapy (RRT) is increasingly utilized to support critically ill patients with severe acute kidney injury (AKI). The clinical dilemma of when to ideally start RRT in these patients has been a longstanding issue that is in need of higher quality evidence to guide clinical practice. When clinicians are confronted with patients with life-threatening complications of AKI, the decision to start RRT is straightforward. However, in the absence of clear indications, the ideal circumstances and timing that balance the perceived benefits and risks of early versus delayed RRT remain uncertain. Survey data have confirmed substantial practice variation in the timing of RRT initiation. Most observational data and small clinical trials have limitations related to confounding by indication, heterogeneity in case-mix and illness severity, and variation in defining timing thresholds for starting RRT. Recently published trials have further added to the clinical uncertainty. This concise review provides an overview of prevailing and evolving evidence on the optimal time to start RRT in critically ill patients with AKI. PMID- 29597217 TI - Prescription and Delivery of the Right Continuous Renal Replacement Therapies Dose. AB - This chapter focuses on the definitions and impact of prescription and delivery of the right dose of treatment in patients on continuous renal replacement therapy (CRRT). We define "dose" and the concepts of efficiency, intensity, and efficacy; differentiate their multiple components; and describe the practical application of those concepts to direct patient care. In the article, we emphasize the effects of delivered dose variation on solute control, and list the main factors affecting CRRT dose delivery. Finally, we summarize the main indicators of dose monitoring and emphasize the importance of an excellent quality control system to ensure appropriate delivery of care to critically ill patients with acute kidney injury. PMID- 29597218 TI - Membranes and Sorbents. AB - For continuous renal replacement therapy (CRRT), the extracorporeal filter provides solute depuration, fluid removal, and control of electrolyte and acid base balance in critically ill patients with acute kidney injury (AKI). The membranes comprising CRRT filters are almost exclusively based on hollow fiber designs and, while adapted from the chronic hemodialysis field, have features that are specific to the requirements of CRRT nevertheless. In addition, these devices have evolved through the 40 years of CRRT in response to changes in clinical practice and the desire to extend the solute removal spectrum. For some critically ill patients, more targeted removal of specific compounds poorly cleared by standard CRRT can be attempted with techniques based on adsorption. Sorbent hemoperfusion is now being applied more broadly in critically ill patients, especially in those with sepsis and systemic inflammation. In this review, the manner in which CRRT membranes and extracorporeal sorbents have evolved over the past 40 years for the treatment of critically ill patients with AKI and other disorders is described. PMID- 29597219 TI - Advances in Machine Technology. AB - Continuous renal replacement therapy (CRRT) machines have evolved into devices specifically designed for critically ill over the past 40 years. In this chapter, a brief history of this evolution is first provided, with emphasis on the manner in which changes have been made to address the specific needs of the critically ill patient with acute kidney injury. Subsequently, specific examples of technology developments for CRRT machines are discussed, including the user interface, pumps, pressure monitoring, safety features, and anticoagulation capabilities. PMID- 29597220 TI - Extra-Renal Indications for Continuous Renal Replacement Therapy. AB - Continuous renal replacement therapy (CRRT) has many potential indications that extend beyond the traditional removal of uremic waste products. Many of these stem from the capacity of CRRT to remove middle-sized molecules and its suitability for haemodynamically unstable patients. Using CRRT for immunomodulation to remove circulating plasma cytokines has created great enthusiasm and, in the past, immunomodulation was a frequently reported indication for commencing CRRT. Unfortunately, recent evidence from randomized controlled trials has been discouraging, and CRRT cannot be recommended for immunomodulation. The contemporary indications of CRRT include fluid removal in fluid overloaded patients with poor tolerance of volume load when other means of fluid removal are insufficient or have failed; removal of toxins such as ammonia and myoglobin, as well as acidosis management in metformin-associated lactic acidosis when severe acid-base disorders coexist. Other potential indications include removal of ingested toxins and tumour lysis syndrome in severely unstable critically ill patients. PMID- 29597221 TI - Technical Complications of Continuous Renal Replacement Therapy. AB - Continuous renal replacement therapy (CRRT) is commonly applied in critically ill patients affected by severe acute kidney injury for solute and volume control and to optimize acid-base and electrolytes balance. Although CRRT represents a life saving procedure for these patients, it is a representation of a non-physiologic artificial kidney and the potential benefits of the treatment could be hampered by clinical and technical side effects. Different parts of the CRRT system can be a source of technical complications. Vascular access dysfunction, activation of the coagulation system, air embolism, heat loss and hypothermia, fluid balance errors, and immune system activation are some issues the medical and nurse staff have to face daily in patients undergoing CRRT. A detailed understanding of these complications and knowledge about the technology that the staff are dealing with are fundamental aspects for applying CRRT safely and efficaciously. PMID- 29597222 TI - Clinical Complications of Continuous Renal Replacement Therapy. AB - The various complications of continuous renal replacement therapy (CRRT) are mostly preventable. Hemodynamic disturbances are dominated by hypotension due to the modification of volume status, myocardial dysfunction, cardiac arrhythmia, or modification of systemic vascular resistances, which are correlated with body temperature changes. Metabolic complications remain at the forefront and have profoundly changed with the use of regional citrate anticoagulation (RCA). RCA may lead to two distinct situations: citrate overload and citrate accumulation, respectively, responsible for metabolic alkalosis and metabolic acidosis. Electrolyte imbalance is also a classic occurrence with RCA. The chelation of cations by citrate results in hypocalcemia and hypomagnesemia in case of inappropriate substitution. Hemorrhagic complications have been drastically reduced mostly for two reasons: the use of systematic ultrasound guidance for the insertion of dialysis catheters and the use of RCA instead of systemic heparin anticoagulation. Hypothermia induced by CRRT and complications associated with prolonged bed rest are also better controlled today. Finally, the removal of undesired substances remains a major issue, especially when it comes to antibiotics, vitamins and micronutrients, molecules for which the intake should be adapted in case of CRRT. PMID- 29597223 TI - Discontinuation of Continuous Renal Replacement Therapy and Dialysis Dependence. AB - Renal replacement therapy (RRT) is a form of extracorporeal support for critical patients, especially for those with acute kidney injury. This therapy enables to gain adequate control over the great metabolic and fluids demand when kidneys are not able to do so; this condition is habitually present in patients who are admitted to intensive care units. However, it is also clear that these patients present a higher mortality rate and, in some cases, complications associated with the therapy. Therefore, it is fundamental to optimize and customize different aspects of RRT that range from the ideal timing including the modality and the dose until its suspension or ending. There currently is a great deal of controversy in all of these RRT-related topics. Although different predictive models have been proposed to determine the optimal timing of therapy discontinuation, nowadays urine output, serum and urine creatinine levels are perhaps the only variables associated with effective discontinuation. Future studies should focus on more accurately predicting renal recovery. This review provides an approach based on current evidence regarding effective discontinuation. PMID- 29597224 TI - Ensuring Quality of Care through Monitoring of Continuous Renal Replacement Therapies. AB - The continuous renal replacement therapy (CRRT) has offered life-saving treatment for kidney failure. Technological advances coupled with findings from clinical trials have allowed for refinements both in the therapy and in the way it is applied to patients. However, outcomes for patients requiring CRRT remain suboptimal. The use of information technology coupled with structured quality improvement programs offers a methodology for studying the delivery of CRRT with an eye toward improving outcomes. Furthermore, integration of information from the CRRT treatment can be combined with real-time data from other patient monitoring sources to create "feedback" loops where more timely changes in the CRRT prescription can occur. It is hoped that these advances may lead to further improvements in patient outcomes. PMID- 29597225 TI - Continuous Renal Replacement Therapy Quality Control and Performance Measures. AB - Continuous renal replacement therapy (CRRT) is one of the most predominant forms of renal replacement therapy (RRT) currently in use now, this therapy being the initial RRT modality in most critically ill patients. However, in general, the quality of CRRT is still suboptimal. The quality of CRRT is affected by many factors, including the optimal prescription and precision delivery, the CRRT providers' professional level, and the CRRT device used. Establishment of a comprehensive quality control system covering all the aspects and procedures of CRRT is essential. Quality measures for structure, process, and outcome of CRRT need to be developed, evaluated, and implemented to ensure the high quality of CRRT. Some CRRT quality improvement methods such as the professional education and specialized team and the application of citrate anticoagulation to extend filter lifespan have been found to be potentially beneficial but need further validation. After all, much work is needed in this field because of the heterogeneity in CRRT practice. More evidence is needed to improve the CRRT quality control system. These are challenges that will need to be addressed in the future. PMID- 29597226 TI - Pediatric Continuous Renal Replacement Therapy for "40 Years of Continuous Renal Replacement Therapy". AB - The provision of continuous renal replacement therapy (CRRT) to pediatric patients presents numerous clinical and technical challenges that have been addressed over the past 40 years. Children provide an informative population for acute kidney injury and CRRT study, as pediatric subspecialists practice with a preventive perspective and children often do not have the multiple severe chronic comorbidities that confound adult studies. In addition, the relatively small number of patients treated at any one pediatric center has engendered successful multicenter collaboration to advance the clinical and technical studies of CRRT provision. This chapter examines pediatric-specific issues and contributions to the CRRT field. PMID- 29597227 TI - From Continuous Renal Replacement Therapies to Multiple Organ Support Therapy. AB - The incidence of the multiple organ dysfunction syndrome (MODS) is rapidly increasing in intensive care units (ICU). It usually combines with sepsis and is the most frequent cause of death in the ICU patients. The nature of the ICU patients has changed in the last years. It includes a variety of patients with severe cases due to major surgical interventions, trauma, hemodynamic instability, sepsis, and so on but also older people than previous times. All these situations can easily lead to MODS. In the prior years, the only available and efficient therapy was renal replacement therapy (RRT) for treating acute renal failure, but the development of technology also gives us devices to support the other systems. The adequacy of any artificial organ support is evaluated by how closely it mimics the flexibility and efficacy of the organ systems it seeks to substitute or support. In a sequence of events, such as that created by sepsis and MODS, all these criteria should be applied at the same time but for different organs and different tasks. RRT and especially continuous renal replacement therapies (CRRT) allowed extracorporeal treatment in critically ill patients with hyper catabolism and fluid overload with excellent hemodynamic stability. New techniques in CRRT as high volume hemofiltration have been applied in septic patients with very promising results. In the light of these observations, a new thought arises: Can extracorporeal blood purification have a positive impact on different organ systems? A possible answer might come from the simple observation that all organs share one aspect in common: contact with blood. All extracorporeal therapies also have one aspect in common: treatment of blood. Based on these observations and knowledge of the molecular biology of sepsis, a "humoral" theory of MODS makes pathophysiological sense and its consequence triggers the need to consider extracorporeal therapies as multiple organ support therapies and not just as single organ support. PMID- 29597229 TI - The Symbol-Digit Modalities Test in Mild Cognitive Impairment: Evidence from Parkinson's Disease Patients. AB - BACKGROUND: The evaluation process of the performance of the symbol-digit modalities test (SDMT) has focused much on numerical scores paying only little attention to the qualitative aspects of performance. Incorporating the gaze analysis technique, we aimed to investigate the performance of Parkinson's disease (PD) patients on the written SDMT task. METHODS: Twelve patients with PD and normal cognition (PD-N), 11 with PD and mild cognitive impairment (PD-MCI), and 13 healthy participants (NC) controlled for age, sex and education were recruited. RESULTS: PD-MCI participants achieved significantly lower scores than NC and PD-N participants. Eye-movement parameters, however, did not differ among the study groups, and were not correlated with task performance. CONCLUSIONS: Impaired performance on the SDMT by PD-MCI participants despite relatively preserved oculomotor performance indicates that lower SDMT scores are not due - even in part - to visuomotor impairments otherwise seen in PD patients. PMID- 29597228 TI - Sexual Behaviour of the Spectral Tarsier (Tarsius spectrum) in Captivity. AB - Tarsius spectrum is a primate species endemic to Sulawesi. Populations of the species have decreased due to habitat destruction and hunting. The sexual behaviour of T. bancanus and T. syrichta are known, but that of T. spectrum has not been reported until recently. The aim of this research was to study the sexual behaviour of T. spectrum in captivity. We observed 3 pairs of T. spectrum at the captive breeding facility of the IPB Primate Research Centre for 9 months using focal animal sampling. We showed that principal courtship behaviours were scent marking (36.7%) and genital marking for females (16.2%) and genital inspection for males (16.0%). Copulations lasted between 3 and 4 min, starting with the male mounting the female and thrusting quickly as many as 168-236 times followed by slow thrusting 9-20 times. When slow thrusting occurred, females vocalized up to 6 times. At the end of the copulation sequence, males remained motionless with their penis inserted within the female's genitalia for about 31 s. Copulation occurred only once for each pair during the observation period. Our results should be useful to support breeding programmes and conservation actions for tarsiers. PMID- 29597230 TI - Membrane-Associated Kaposi Sarcoma-Associated Herpesvirus Glycoprotein B Promotes Cell Adhesion and Inhibits Migration of Cells via Upregulating IL-1beta and TNF alpha. AB - OBJECTIVES: Kaposi sarcoma-associated herpesvirus (KSHV) glycoprotein B (gB) is expressed on the viral envelope as well as on the cytoplasmic membrane of infected cells. In the current study, we aimed to decipher the impact of membrane associated gB on adhesion and migration of cells via modulating the expression of cytokines. METHODS: A combination of polymerase chain reaction array, cell adhesion assay, and wound-healing migration assay was conducted to study the influence of the gB-induced cytokines on cell adhesion and migration. RESULTS: Membrane-associated gB was demonstrated to significantly upregulate the expression of IL-1beta and TNF-alpha. Elevated levels of these cytokines were observed in conditioned medium (CM) collected from gB-expressing cells (gB-CM) compared to CM collected from untransfected cells or cells transfected with empty vector. KSHV gB-induced IL-1beta and TNF-alpha play a role in the ability of gB CM to mediate cell adhesion while inhibiting migration. CONCLUSION: Our results provide novel evidence that demonstrates full-length gB expressed on cell membrane to mediate adhesion and inhibit migration of cells not only by autocrine mechanism mediated by RGD-based interactions [Hussein et al.: BMC Cancer 2016; 16: 148], but also by paracrine mechanism mediated by gB-induced IL-1beta and TNF alpha. PMID- 29597231 TI - Physiology of the Calcium-Parathyroid Hormone-Vitamin D Axis. AB - Classic endocrine feedback loops ensure the regulation of blood calcium. Calcium in the extracellular fluid (ECF) binds and activates the calcium sensing receptor (CaSR) on the parathyroid cells, leading to an increase in intracellular calcium. This in turn leads to a reduced parathyroid hormone (PTH) release. Hypocalcemia leads to the opposite sequence of events, namely, lowered intracellular calcium and increased PTH production and secretion. PTH rapidly increases renal calcium reabsorption and, over hours to days, enhances osteoclastic bone resorption and liberates both calcium and phosphate from the skeleton. PTH also increases fibroblast growth factor 23 (FGF23) release from mature osteoblasts and osteocytes. PTH stimulates the renal conversion of 25-hydroxyvitamin D (25[OH]D) to 1,25(OH)2D, likely over several hours, which in turn will augment intestinal calcium absorption. Prolonged hypocalcemia and exposure to elevated PTH may also result in 1,25(OH)2D-mediated calcium and phosphorus release from bone. These effects restore the ECF calcium to normal and inhibit further production of PTH and 1,25(OH)2D. Additionally, FGF23 can be released from bone by 1,25(OH)2D and can in turn reduce 1,25(OH)2D concentrations. FGF23 has also been reported to decrease PTH production. When ECF calcium is in the hypercalcemic range, PTH secretion is reduced and renal 1,25(OH)2D production is decreased. In addition, the elevated calcium per se stimulates the renal CaSR, thus inducing calciuria. Therefore, suppression of PTH release and 1,25(OH)2D synthesis and stimulation of the renal CaSR lead to reduced renal calcium reabsorption, decreased skeletal calcium release, and decreased intestinal calcium absorption, resulting in the normalization of the elevated ECF calcium. PMID- 29597232 TI - Preliminaries. PMID- 29597233 TI - Vitamin D Assays. AB - The number of requests for vitamin D metabolite measurements has increased dramatically over the past decade leading commercial laboratories to develop rapid high throughput assays. The measurement of 25-hydroxyvitamin D (25[OH]D) and to a lesser extent 1,25-dihydroxyvitamin D (1,25[OH]2D) dominates these requests, but requests for multiple metabolite measurements in the same sample are also increasing. The most commonly used methods include immunoassays and liquid chromatography/mass spectrometry (LC-MS). Each method has its advantages and disadvantages, but with improvements in technology, especially in LC-MS, this method is gaining ascendance due to its greater precision and flexibility. The use of standards from the National Institutes of Standards and Technology has substantially reduced the variability from laboratory to laboratory, thereby improving the reliability of these measurements. Although the current demand is for measurement of total vitamin D metabolite levels, these metabolites circulate in blood tightly bound to vitamin D binding protein (DBP) and albumin with less than 1% free. The free concentration may be a more accurate indicator of vitamin D status especially in individuals with DBP levels that deviate from the normal population. Thus, methods to measure the free concentration at least of 25(OH)D are becoming available and may supplement if not replace measurements of total levels. PMID- 29597234 TI - New Concepts in Vitamin D Requirements for Children and Adolescents: A Controversy Revisited. AB - North American and European authorities have identified thresholds up to 50 nmol/L serum 25-hydroxyvitamin D (25[OH]D) as optimal for pediatric vitamin D status. These recommendations are relative to skeletal endpoints, as vitamin D plays a pivotal role in bone mineral content (BMC) accretion. Suboptimal vitamin D consumption during youth may therefore hinder BMC acquisition, and contribute to an increased fracture risk. Though vitamin D requirements range between 400 and 800 IU/day, not all children achieve this. To encourage adequate vitamin D consumption, strategies such as supplementation, food labeling, and fortification, are currently being investigated. There is moderate support for the role of vitamin D supplementation on adolescent BMC accrual; however, factors such as age, maturation, population ancestry, and latitude, are not consistently accounted for across studies. Vitamin D is also linked with extraskeletal endpoints (e.g., muscle mass/function, adiposity, and metabolic health) in children, but the cross-sectional data do not necessarily align with results from experimental trials. Based on the evidence currently available, there is no need for a revision of the pediatric vitamin D recommendations at this time. Additional trials are required, however, to build upon the hypothesis-generating observational data, and to provide evidence for future vitamin D requirements across the globe. PMID- 29597235 TI - Practical Issues in Vitamin D Replacement. AB - Practical clinical guidance for vitamin D assessment and management relies on a strong evidence base, but unfortunately there are many deficiencies in our current knowledge. For the general population the Institute of Medicine recommendations are likely to provide adequate vitamin D levels without harms. Thus, most adults should ingest 600-800 IU (international units) in diet and supplements with up to 4,000 IU daily likely to be safe. In certain populations, such as those with osteoporosis or after bariatric surgery, it is important to know the levels of circulating 25-hydroxyvitamin D, but general screening has not been shown to improve health. One expert group has recommended a "reasonable" level of 30 ng/mL in those individuals for whom testing is required. PMID- 29597236 TI - Extra-Skeletal Effects of Vitamin D. AB - There are very solid data to confirm that the vitamin D endocrine system is important not only for calcium transport or bone homeostasis but also for operational functions in most cells of the body. Preclinical studies convincingly demonstrated coherent actions of the vitamin D endocrine system on the proliferation/differentiation of most cells (and thus possibly on the evolution of cancer). The most plausible target tissues include skeletal and cardiac muscle, all immune cells, many cells involved in cardiovascular homeostasis, brain cells, and reproductive tissues. These data have been generated in models of (near) total absence of vitamin D action or when exposed to very high concentrations of the active hormone, 1,25-dihydroxyvitamin D or its analogs. In humans, observational data frequently demonstrate a link between poor vitamin D status and a large number of major human diseases such as cancer, muscle weakness and falls, infections or autoimmune diseases, hypertension and cardiovascular risks and events, obesity, diabetes and all aspects of the metabolic syndrome, and other health problems. Intervention studies so far have not convincingly demonstrated a positive effect on such extra-skeletal health outcomes. A very large number of ongoing studies (about 3,000), however, should help to clarify the role of vitamin D on the musculoskeletal system and on global health. PMID- 29597237 TI - Vitamin D and Secondary Hyperparathyroid States. AB - The interplay between vitamin D and parathyroid hormone (PTH) represents one of the most important metabolic mechanisms of regulation of the calcium/phosphorus homeostasis. Secondary hyperparathyroidism is therefore a major complication that arises as a result of reduced vitamin D levels, both as primary 25-hydroxy vitamin D (25[OH]D) and/or 1,25-dihydroxyvitamin D (1,25[OH]2D) reduction. Different metabolic pathways are involved, as well as target organs and tissues, with several clinical complications. The skeleton is primarily involved, but many other extra-skeletal organs expressing the vitamin D and/or PTH receptors may theoretically be affected by vitamin D inadequacy and secondary hyperparathyroidism. Mechanisms associated with low vitamin D (mostly, but not exclusively 1,25[OH]2D deficiency) and high serum PTH also intensify chronic kidney disease (CKD), with further consequences on the mineral metabolism system and development of skeletal and cardiovascular disease. Therapeutic intervention is primarily aimed at enhancing serum 25(OH)D levels and reducing secondary hyperparathyroidism, by employing different strategies and endpoints according to the clinical contest. This chapter reviews the current knowledge on the metabolic pathways involved in the vitamin D/PTH axis regulation in different clinical settings and gives an update on the recommended treatment strategies. PMID- 29597238 TI - Vitamin D and Diabetes Mellitus. AB - Vitamin D has been suggested as a protective compound for diabetes mellitus. Several mechanisms linking vitamin D to the regulation of the immune response support a role for vitamin D in the pathogenesis of autoimmune diabetes. Epidemiological evidence and observational studies suggesting that adequate vitamin D status is related to decreased risk of developing type 1 diabetes further corroborates this concept. However, only few and mostly underpowered randomized clinical trials have been conducted to test the effectiveness of vitamin D supplementation in autoimmune diabetes, with disappointing results. Similarly, recent evidence linking vitamin D action to insulin secretion and sensitivity led to the hypothesis that this compound may play a key role in the regulation of glucose homeostasis in both pre-diabetes and overt type 2 diabetes (T2D). However, the main clinical trials evaluating the efficacy of vitamin D supplementation for the control of glucose homeostasis in people at risk for or affected by T2D have yielded inconsistent results. The aim of this review is to summarize the rationale and results of randomized clinical trials testing vitamin D and its analogs in both autoimmune and T2D. PMID- 29597239 TI - Mammary Hibernoma: A Case Report of a Rare Disease. AB - Mammary hibernomas are extremely rare benign tumors composed of brown fat cells, with only five cases previously reported in the literature. We report the case of a 42-year-old female patient with a painless growing mass in her right breast. A partial mastectomy was performed, and the diagnosis of hibernoma was confirmed by the histological features and the immunohistochemical profile. Although hibernoma is a benign tumor, its main differential diagnoses include aggressive lesions, making the accurate diagnosis essential to provide adequate care to the patient. PMID- 29597240 TI - Maternal Asthma Is an Independent Risk Factor for Long-Term Respiratory Morbidity of the Offspring. AB - OBJECTIVE: The objective of this study was to investigate whether maternal bronchial asthma increases the risk for long-term respiratory morbidity of the offspring. STUDY DESIGN: A population-based cohort study compared the incidence of long-term pediatric hospitalizations due to respiratory disease of the offspring of mothers with and without bronchial asthma. Deliveries occurred between the years 1991 and 2014 in a tertiary medical center. Congenital malformations as well as multiple pregnancies were excluded. Kaplan-Meier's survival curve was used to estimate cumulative incidence of respiratory morbidity. A multivariate generalized estimating equation (GEE) logistic regression model analysis was used to control for confounders. RESULTS: During the study period, 253,808 deliveries met the inclusion criteria; of which 1.3% were born to mothers with bronchial asthma (n = 3,411). During the follow-up period, children born to women with bronchial asthma had a significantly higher rate of long-term respiratory morbidity (odds ratio [OR] = 1.5; 95% confidence interval [CI] = 1.3-1.7; p < 0.001). Specifically, the rate of childhood asthma was higher among offspring of mothers with asthma (OR = 2.3; 95% CI = 1.8-2.9; p < 0.001). Children born to women with asthma had higher cumulative incidence of respiratory morbidity, using a Kaplan-Meier's survival curve (log-rank test; p < 0.001). Using two multivariable GEE logistic regression models, controlling for the time to event, maternal age, and gestational age at delivery, maternal bronchial asthma was found to be an independent risk factor for long-term respiratory disease of the offspring (adjusted OR = 1.6; 95% CI = 1.4-1.9; p < 0.001), and specifically for bronchial asthma (adjusted OR = 2.5; 95% CI = 1.9 3.1; p < 0.001). CONCLUSION: Maternal bronchial asthma is an independent risk factor for long-term respiratory morbidity of the offspring.

AB - Four novel lentinoids (1-4), along with the known compounds striguellone A (5), isopanepoxydone (6) and panepoxydone (7), were isolated as part of our studies on Lentinus strigellus. The structures of 1-4 have been established by 1D- and 2D NMR and MS analysis. Compounds (1-3) and (5-7) were tested against Listeria monocytogenes, Enterococcus faecalis, Pseudomonas aeruginosa and Klebsiella pneumoniae. These compounds showed inhibition diameters ranging from 7.5-9.5 mm, however, when the minimum inhibitory concentration (MIC) was determined, only compound 1 showed a significant activity of 200 MUg/mL. Intermediates for the biosynthesis of the oxygenated cyclohexenyl derivatives isolated from lentinoid fungi (genera Lentinus and Panus) are proposed. PMID- 29597243 TI - Evaluation of an Agricultural Meteorological Disaster Based on Multiple Criterion Decision Making and Evolutionary Algorithm. AB - The evaluation of a meteorological disaster can be regarded as a multiple criteria decision making problem because it involves many indexes. Firstly, a comprehensive indexing system for an agricultural meteorological disaster is proposed, which includes the disaster rate, the inundated rate, and the complete loss rate. Following this, the relative weights of the three criteria are acquired using a novel proposed evolutionary algorithm. The proposed algorithm consists of a differential evolution algorithm and an evolution strategy. Finally, a novel evaluation model, based on the proposed algorithm and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), is presented to estimate the agricultural meteorological disaster of 2008 in China. The geographic information system (GIS) technique is employed to depict the disaster. The experimental results demonstrated that the agricultural meteorological disaster of 2008 was very serious, especially in Hunan and Hubei provinces. Some useful suggestions are provided to relieve agriculture meteorological disasters. PMID- 29597244 TI - Fractionation, Bioaccessibility, and Risk Assessment of Heavy Metals in the Soil of an Urban Recreational Area Amended with Composted Sewage Sludge. AB - A composted sewage sludge (CSS) was added to the soil of an urban garden at 5%, 10%, and 25% (w/w soil) and stabilised for 180 days. Samples were then collected and analysed for total heavy metal concentrations, chemical fractions, and bioaccessibility, together with some physicochemical properties. The results showed that the total chromium (Cr), copper (Cu), lead (Pb), and zinc (Zn) concentrations were increased with CSS addition rate. The CSS addition decreased the residual fractions of these four elements. The exchangeable Cr, Cu, and Pb fractions were very small or not detected, while Zn exhibited an increasing trend in its exchangeable fraction with CSS addition rate. The bioaccessibility of these four elements was increased with the CSS addition rate. Moreover, the Cr, Cu, and Zn bioaccessibility correlated positively with the total concentration, while the bioaccessibility of these four elements exhibited a negative correlation with the residual fraction. The fractionation and bioaccessibility of heavy metals may have also been influenced by pH, cation exchange capacity, and organic matter. The risk assessment code reflected the amended soil showed no or low environmental risks for Cr, Cu, and Pb and a medium risk for Zn. The hazardous index values and cancer risk levels indicated that the heavy metals in the soil amended with 25% CSS posed negligible potential noncarcinogenic and carcinogenic risks to children and adults via incidental ingestion. PMID- 29597245 TI - The Relevancy of paracetamol and Breastfeeding Post Infant Vaccination: A Systematic Review. AB - Background: Paracetamol may be used as an antipyretic agent for the treatment of fever, as well as an analgesic in the treatment of mild to moderate pain post vaccination in infants. The use of paracetamol during fever may be or may not be recommended since it may alter the natural human body immune response, although it may reduce pain. Objectives: The aims of this study are to describe the effectiveness of breastfeeding in reducing pain and paracetamol in reducing fever and pain post infant vaccination. Methods: Data sources and study selection was conducted by electronic searching of six databases. Manual reference checks of all articles on paracetamol and breastfeeding post infant vaccination published in the English language between 1978 and 2017. Two levels of screening were used on 9614 citations, which include screening of abstracts and titles followed by full text screening. The data synthesis were tabulated into study characteristics, quality, and effects. Results: Systematic review of breastfeeding included three studies from 9614 database searches found significant benefit from breastfeeding in pain scores and the duration of crying, as well as behavioural changes. None of the studies stated the detriment of breastfeeding before, during, and after immunization. Systematic review of paracetamol effectiveness included four studies from 1177 database searches found significant benefit from prophylaxis paracetamol in fever, one study found significant benefit from prophylaxis paracetamol in fussiness, and one study's results were found to be not significant. Two studies on evaluating the safety of prophylactic paracetamol in 2009 found that antibody responses to several antigens were significantly reduced, and the other study in 1988 found that antibody titres to DTP bacteria of placebo and PCM did not differ significantly. Conclusions: The relevancy of giving paracetamol post all types of vaccination may be questionable. Breastfeeding before, during, and after immunization are recommended for pain reduction and are proven effective. Further research is required in deciding if paracetamol is to be of rational use following infant immunization. PMID- 29597246 TI - Importance of Patient-Provider Communication to Adherence in Adolescents with Type 1 Diabetes. AB - Effective communication between pediatric diabetes patients and their providers has the potential to enhance patient satisfaction and health outcomes, as well as improve diabetes-related self-management. In this review, we highlight the importance of communication between patients and providers, focusing on the effect of communication on adherence in the high-risk population of adolescents with type 1 diabetes. We synthesize the literature describing patient-provider communication in pediatric populations and provide implications for practice that focus on the most relevant, modifiable factors for improving self-management in adolescents with type 1 diabetes. PMID- 29597247 TI - Home Hospitalization for Acute Decompensated Heart Failure: Opportunities and Strategies for Improved Health Outcomes. AB - IMPORTANCE: Heart failure (HF) is the leading cause of hospitalization among patients over the age of 65 in the United States and developed countries, posing a significant economic burden to the health care systems. More than half of the patients with HF will be readmitted to the hospital within 6 months from discharge, leading not only to increased health care related expenses but also functional decline, iatrogenic injuries and in-hospital infections. With the increasing prevalence of HF, there is a substantial need for innovative delivery care models that can provide hospital level of care at a patient's home. OBSERVATIONS: Home hospitalization was originally used to safely manage chronically ill patients with general medical (stroke, chronic obstructive pulmonary disease, deep vein thrombosis, community acquired pneumonia) and surgical conditions and was associated with improved patient satisfaction and improvement in activity of daily living status. This had no clear effect on readmission or cost. When hospital at home care model was applied to HF patients it demonstrated increased time to readmission, reduced index costs and improved health related quality of life, with no significant differences in adverse events. Eligible patients should be selected based on multiple factors taking into consideration applicable limitations and comorbidities. CONCLUSIONS AND RELEVANCE: Providing in-hospital level care to the patient's house presents a reliable alternative, yielding multiple benefits both for the patient, as well as the health care system. Formulating a well-defined model is necessary before wide implementation. PMID- 29597248 TI - N- and C-Modified TiO2 Nanotube Arrays: Enhanced Photoelectrochemical Properties and Effect of Nanotubes Length on Photoconversion Efficiency. AB - In this investigation, a new, facile, low cost and environmental-friendly method was introduced to fabricate N- and C-modified TiO2 nanotube arrays by immersing the as-anodized TiO2 nanotube arrays (TNTAs) in a urea aqueous solution with mechanical agitation for a short time and keeping the TNTAs immersed in the solution for 6 h at room temperature. Then, the TNTAs were annealed at different temperatures. The produced N-, C-modified TNTAs were characterized using FESEM, EDX, XRD, XPS, UV-Vis diffuse reflectance spectra. Modified optical properties with narrow band gap energy, Eg, of 2.65 eV was obtained after annealing the modified TNTAs at 550 °C. Modified TNTAs showed enhanced photoelectochemical performance. Photoconversion efficiency (PCE) was increased from 4.35% for pristine (unmodified) TNTAs to 5.18% for modified TNTAs, an increase of 19%. Effect of nanotubes length of modified TNTAs on photoelectrochemical performance was also studied. Photocurrent density and PCE were increased by increasing nanotube length with a maximum PCE of 6.38% for nanotube length of 55 µm. This high PCE value was attributed to: band gap reduction due to C- and N modification of TNTAs surface, increased surface area of long TNTAs compared with short TNTAs, investigated in previous studies.

AB - Many neurological diseases (ischemic and hemorrhagic stroke, multiple sclerosis, infant cerebral palsy, spinal cord injuries, traumatic brain injury, and other cerebrovascular disorders) may cause muscle spasticity. Different therapeutic strategies have been proposed for the treatment of spasticity. One of the major treatments for tone modulation is botulinum toxin type A (BTX-A), performed in addition to other rehabilitation strategies based on individualized multidisciplinary programs aimed at achieving certain goals for each patient. Therapeutic plans must be precisely defined as they must balance the reduction of spastic hypertonia and retention of residual motor function. To perform and optimize the treatment, an accurate clinical and instrumental evaluation of spasticity is needed to determine how this symptom is invalidating and to choose the best doses, muscles and times of injection in each patient. We introduce an “appropriate treatment” and no “standard or high dosage treatment” concept based on our retrospective observational study on 120 patients lasting two years, according to the larger Therapeutic Index and Therapeutic Window of Incobotulinumtoxin A doses from 100 to 1000 units. We studied the efficiency and safety of this drug considering the clinical spasticity significance for specialist physicians and patients. PMID- 29597250 TI - Expression of TIM-3 on Plasmacytoid Dendritic Cells as a Predictive Biomarker of Decline in HIV-1 RNA Level during ART. AB - Depletion and functional impairment of circulating plasmacytoid dendritic cells (pDCs) are characteristic attributes of HIV-1-infection. The mechanism of dysfunction of pDCs is unclear. Here, we studied the development of phenotype of pDCs in a cohort of HIV-1-infected individuals monitored before the initiation and during a 9-month follow up with antiretroviral therapy (ART). Using polychromatic flow cytometry, we detected significantly higher pDC-surface expression of the HIV-1 receptor CD4, regulatory receptor BDCA-2, Fcγ receptor CD32, pDC dysfunction marker TIM-3, and the marker of killer pDC, TRAIL, in treatment-naïve HIV-1-infected individuals before initiation of ART when compared to healthy donors. After 9 months of ART, all of these markers approached but did not reach the expression levels observed in healthy donors. We found that the rate of decline in HIV-1 RNA level over the first 3 months of ART negatively correlated with the expression of TIM-3 on pDCs. We conclude that immunogenic phenotype of pDCs is not significantly restored after sustained suppression of HIV-1 RNA level in ART-treated patients and that the level of the TIM-3 expressed on pDCs in treatment naïve patients could be a predictive marker of the rate of decline in the HIV-1 RNA level during ART. PMID- 29597253 TI - Flexible Gas Sensors Employing Octahedral Indium Oxide Films. AB - Indium oxide octahedral nanopowders were obtained from an ionic precursor compound after an oxidation process conducted under a low-oxygen atmosphere. This method was found to produce contamination-free indium oxide nanomaterial with very similar morphological and crystalline properties to the one produced by vapor-phase transport, but at significantly lower temperatures and higher yield. The as-synthesized indium oxide was mixed to an organic vehicle and microdrop deposited to form a film bridging the interdigitated silver electrodes patterned on top of a flexible, polyimide (Kapton®), substrate. The gas sensing properties of the flexible chemoresistors towards ammonia vapors, hydrogen, and nitrogen dioxide were investigated. It was found that these sensors were remarkably sensitive to nitrogen dioxide at a low operating temperature of 150 °C. These results are consistent with the performance of vapor-phase transport synthesized indium oxide octahedra sensors on rigid, ceramic substrates. Therefore, the results presented here pave the way for the mass production of inexpensive gas sensors onto flexible substrates via additive manufacturing. PMID- 29597249 TI - The Role of Activator Protein-1 (AP-1) Family Members in CD30-Positive Lymphomas. AB - The Activator Protein-1 (AP-1) transcription factor (TF) family, composed of a variety of members including c-JUN, c-FOS and ATF, is involved in mediating many biological processes such as proliferation, differentiation and cell death. Since their discovery, the role of AP-1 TFs in cancer development has been extensively analysed. Multiple in vitro and in vivo studies have highlighted the complexity of these TFs, mainly due to their cell-type specific homo- or hetero-dimerization resulting in diverse transcriptional response profiles. However, as a result of the increasing knowledge of the role of AP-1 TFs in disease, these TFs are being recognized as promising therapeutic targets for various malignancies. In this review, we focus on the impact of deregulated expression of AP-1 TFs in CD30 positive lymphomas including Classical Hodgkin Lymphoma and Anaplastic Large Cell Lymphoma.

AB - Silica nanoparticles are widely studied in emerging areas of nanomedicine because they are biocompatible, and their surface can be modified to provide functionalization. The size is intrinsically related to the performance of the silica nanoparticles; therefore, it is important to have control over the size. However, the silica nanoparticles obtained from sodium metasilicate are less studied than those obtained from tetraethyl orthosilicate. Moreover, the methods of surface modification involve several steps after the synthesis. In this work, the effect of different concentrations of sodium metasilicate on the size of silica nanoparticles was studied. In the same way, we studied the synthesis of organically modified silica nanoparticles in a one-step method, using poly(ethylene glycol). The nanoparticles were characterized by scanning electron microscopy, Fourier-transform infrared spectroscopy, and thermogravimetric analysis. It was found that the size distribution of the silica nanoparticles could be modified by changing the initial concentration of sodium metasilicate. The one-step surface-modification method caused a significant decrease in size distribution.

AB - Most cinnamic acids, their esters, amides, aldehydes, and alcohols present several therapeutic actions through anti-inflammatory, antitumor, and inhibitory activity against a great variety of microorganisms. In this work, eight amines derived from cinnamic acid were synthesized and tested against host cells infected with Toxoplasma gondii and the bacteria Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and three strains of Staphylococcus aureus. Compounds 3 and 4 showed the best result against intracellular T. gondii, presenting antiparasitic activity at low concentrations (0.38 and 0.77 mM). The antibacterial activity of these compounds was also evaluated by the agar microdilution method, and amides 2 and 5 had a minimum inhibitory concentration of 250 ug mL-1 against two strains of S. aureus (ATCC 25923 and bovine strain LSA 88). These also showed synergistic action along with a variety of antibiotics, demonstrating that amines derived from cinnamic acid have potential as pharmacological agents. PMID- 29597256 TI - Geospatial Analysis and Seasonal Distribution of West Nile Virus Vectors (Diptera: Culicidae) in Southern Ontario, Canada. AB - The purpose of this study was to establish geospatial and seasonal distributions of West Nile virus vectors in southern Ontario, Canada using historical surveillance data from 2002 to 2014. We set out to produce mosquito abundance prediction surfaces for each of Ontario's thirteen West Nile virus vectors. We also set out to determine whether elevation and proximity to conservation areas and provincial parks, wetlands, and population centres could be used to improve our model. Our results indicated that the data sets for Anopheles quadrimaculatus, Anopheles punctipennis, Anopheles walkeri, Culex salinarius, Culex tarsalis, Ochlerotatus stimulans, and Ochlerotatus triseriatus were not suitable for geospatial modelling because they are randomly distributed throughout Ontario. Spatial prediction surfaces were created for Aedes japonicus and proximity to wetlands, Aedes vexans and proximity to population centres, Culex pipiens/restuans and proximity to population centres, Ochlerotatus canadensis and elevation, and Ochlerotatus trivittatus and proximity to population centres using kriging. Seasonal distributions are presented for all thirteen species. We have identified both when and where vector species are most abundant in southern Ontario. These data have the potential to contribute to a more efficient and focused larvicide program and West Nile virus awareness campaigns. PMID- 29597257 TI - Evaluation of UV Curing Properties of Mixture Systems with Differently Sized Monomers. AB - Ultraviolet (UV) curing is a photopolymerization technique resulting in a three dimensional polymer network from monomers and oligomers after exposure to UV light, which is often used for fusion industry. However, shrinkage is an issue that needs to be resolved. Studies of single substances have been extensively conducted, but studies of mixture systems have not sufficiently been undertaken. In this study, we evaluate the shrinkage phenomenon by studying a monomer/monomer binary system and monomer/macromer composite systems. Shrinkage tends to increase when compounds varying in size are used. Similar to the shrinkage phenomenon, the curing rate is also relatively higher in such systems. These synergistic effects are evaluated to be due to the nano-porous effect, and vary with the composition ratio and material structure.

AB - Co0.5Ni0.5Fe2O4 fibers with a diameter of about 270 nm and a length of about 10 MUm were synthesized by a microemulsion-mediated solvothermal method with subsequent heat treatment. The Co0.5Ni0.5Fe2O4 fibers/reduced graphene oxide (RGO) composite was prepared by a facile in-situ chemical reduction method. The crystalline structures and morphologies were investigated based on X-ray diffraction patterns and scanning electron microscopy. Magnetization measurements were carried out using a vibrating sample magnetometer at room temperature. Co0.5Ni0.5Fe2O4 fibers/RGO composites achieve both a wider and stronger absorption and an adjustable surface wave attenuation compared with Co0.5Ni0.5Fe2O4 fibers, indicating the potential for application as advanced microwave absorbers. PMID- 29597259 TI - The Role of Circulating Free DNA and MicroRNA in Non-Invasive Diagnosis of HBV- and HCV-Related Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) is the third and the fifth leading cause of cancer related death worldwide in men and in women, respectively. HCC generally has a poor prognosis, with a very low 5-year overall survival, due to delayed diagnosis and treatment. Early tumour detection and timely intervention are the best strategies to reduce morbidity and mortality in HCC patients. Histological evaluation of liver biopsies is the gold standard for cancer diagnosis, although it is an invasive, time-consuming and expensive procedure. Recently, the analysis of circulating free DNA (cfDNA) and RNA molecules released by tumour cells in body fluids, such as blood serum, saliva and urine, has attracted great interest for development of diagnostic assays based on circulating liver cancer molecular biomarkers. Such "liquid biopsies" have shown to be useful for the identification of specific molecular signatures in nucleic acids released by cancer cells, such as gene mutations and altered methylation of DNA as well as variations in the levels of circulating microRNAs (miRNAs) and long non-coding RNAs (lncRNAs). Body fluids analysis may represent a valuable strategy to monitor liver disease progression in subjects chronically infected with hepatitis viruses or cancer relapse in HCC treated patients. Several studies showed that qualitative and quantitative assays evaluating molecular profiles of circulating cell-free nucleic acids could be successfully employed for early diagnosis and therapeutic management of HCC patients. This review describes the state of art on the use of liquid biopsy for cancer driver gene mutations, deregulated DNA methylation as well as miRNA levels in HCC diagnosis. PMID- 29597260 TI - The Impact of Carnitine on Dietary Fiber and Gut Bacteria Metabolism and Their Mutual Interaction in Monogastrics. AB - Carnitine has vital roles in the endogenous metabolism of short chain fatty acids. It can protect and support gut microbial species, and some dietary fibers can reduce the available iron involved in the bioactivity of carnitine. There is also an antagonistic relationship between high microbial populations and carnitine bioavailability. This review shows the interactions between carnitine and gut microbial composition. It also elucidates the role of carnitine bacterial metabolism, mitochondrial function, fiber fermentability, and short chain fatty acids (SCFAs). PMID- 29597261 TI - Dietary Intakes of EPA and DHA Omega-3 Fatty Acids among US Childbearing-Age and Pregnant Women: An Analysis of NHANES 2001-2014. AB - BACKGROUND: The 2015–2020 Dietary Guidelines for Americans (DGA) recommend that the general population should consume about 8 ounces (oz.) per week of a variety of seafood, providing approximately 250 mg per day of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and that pregnant and lactating women should consume 8–12 oz. per week of seafood. METHODS: We determined the usual intakes, percentage not meeting recommendations, and trends in EPA and DHA intakes among childbearing-age and pregnant women (15–44 years of age) using the NHANES cycles 2001–2002 through 2013–2014. RESULTS: For the childbearing-age women, the mean usual intake of seafood was 0.44 ± 0.02 oz. equivalent per day and 100% of the population was below the DGA recommendation. Mean usual intakes of EPA, DHA, and combined EPA and DHA from foods and dietary supplements combined were 26.8 ± 1.4, 62.2 ± 1.9, and 88.1 ± 3.0 mg per day, respectively. Over 95% of the sample did not meet the daily intakes of 250 mg EPA and DHA. Similar results were observed for pregnant women. After controlling for covariates, there were slight but significant increases in EPA and DHA intakes from foods and dietary supplements over the 14-year span among childbearing-age (p = 0.005) and pregnant women (p = 0.002). CONCLUSIONS: It was estimated that a majority of U.S. childbearing-age and pregnant women consumed significantly lower amounts of seafood than what the DGA recommends, which subsequently leads to low intakes of EPA and DHA; in addition, dietary supplement use has not eliminated the nutrient shortfall. PMID- 29597262 TI - Maternal Choline Supplementation during Normal Murine Pregnancy Alters the Placental Epigenome: Results of an Exploratory Study. AB - The placental epigenome regulates processes that affect placental and fetal development, and could be mediating some of the reported effects of maternal choline supplementation (MCS) on placental vascular development and nutrient delivery. As an extension of work previously conducted in pregnant mice, the current study sought to explore the effects of MCS on various epigenetic markers in the placenta. RNA and DNA were extracted from placentas collected on embryonic day 15.5 from pregnant mice fed a 1X or 4X choline diet, and were subjected to genome-wide sequencing procedures or mass-spectrometry-based assays to examine placental imprinted gene expression, DNA methylation patterns, and microRNA (miRNA) abundance. MCS yielded a higher (fold change = 1.63-2.25) expression of four imprinted genes (Ampd3, Tfpi2, Gatm and Aqp1) in the female placentas and a lower (fold change = 0.46-0.62) expression of three imprinted genes (Dcn, Qpct and Tnfrsf23) in the male placentas (false discovery rate (FDR) <= 0.05 for both sexes). Methylation in the promoter regions of these genes and global placental DNA methylation were also affected (p <= 0.05). Additionally, a lower (fold change = 0.3; Punadjusted = 2.05 * 10-4; FDR = 0.13) abundance of miR-2137 and a higher (fold change = 1.25-3.92; p < 0.05) expression of its target genes were detected in the 4X choline placentas. These data demonstrate that the placental epigenome is responsive to maternal choline intake during murine pregnancy and likely mediates some of the previously described choline-induced effects on placental and fetal outcomes.

AB - Self-loosening of bolts caused by repetitive loads and vibrations is one of the common defects that can weaken the structural integrity of bolted steel joints in civil structures. Many existing approaches for detecting loosening bolts are based on physical sensors and, hence, require extensive sensor deployment, which limit their abilities to cost-effectively detect loosened bolts in a large number of steel joints. Recently, computer vision-based structural health monitoring (SHM) technologies have demonstrated great potential for damage detection due to the benefits of being low cost, easy to deploy, and contactless. In this study, we propose a vision-based non-contact bolt loosening detection method that uses a consumer-grade digital camera. Two images of the monitored steel joint are first collected during different inspection periods and then aligned through two image registration processes. If the bolt experiences rotation between inspections, it will introduce differential features in the registration errors, serving as a good indicator for bolt loosening detection. The performance and robustness of this approach have been validated through a series of experimental investigations using three laboratory setups including a gusset plate on a cross frame, a column flange, and a girder web. The bolt loosening detection results are presented for easy interpretation such that informed decisions can be made about the detected loosened bolts. PMID- 29597263 TI - PON-tstab: Protein Variant Stability Predictor. Importance of Training Data Quality. AB - Several methods have been developed to predict effects of amino acid substitutions on protein stability. Benchmark datasets are essential for method training and testing and have numerous requirements including that the data is representative for the investigated phenomenon. Available machine learning algorithms for variant stability have all been trained with ProTherm data. We noticed a number of issues with the contents, quality and relevance of the database. There were errors, but also features that had not been clearly communicated. Consequently, all machine learning variant stability predictors have been trained on biased and incorrect data. We obtained a corrected dataset and trained a random forests-based tool, PON-tstab, applicable to variants in any organism. Our results highlight the importance of the benchmark quality, suitability and appropriateness. Predictions are provided for three categories: stability decreasing, increasing and those not affecting stability. PMID- 29597265 TI - Direct Printing of Stretchable Elastomers for Highly Sensitive Capillary Pressure Sensors. AB - We demonstrate the successful fabrication of highly sensitive capillary pressure sensors using an innovative 3D printing method. Unlike conventional capacitive pressure sensors where the capacitance changes were due to the pressure-induced interspace variations between the parallel plate electrodes, in our capillary sensors the capacitance was determined by the extrusion and extraction of liquid medium and consequent changes of dielectric constants. Significant pressure sensitivity advances up to 547.9 KPa-1 were achieved. Moreover, we suggest that our innovative capillary pressure sensors can adopt a wide range of liquid mediums, such as ethanol, deionized water, and their mixtures. The devices also showed stable performances upon repeated pressing cycles. The direct and versatile printing method combined with the significant performance advances are expected to find important applications in future stretchable and wearable electronics. PMID- 29597267 TI - Study on the Visible-Light Photocatalytic Performance and Degradation Mechanism of Diclofenac Sodium under the System of Hetero-Structural CuBi2O4/Ag3PO4 with H2O2. AB - Two kinds of CuBi2O4/Ag3PO4 with different heterojunction structures were prepared based on the combination of hydrothermal and in-situ precipitation methods with surfactant additives (sodium citrate and sodium stearate), and their characteristics were systematically resolved by X-ray Diffraction (XRD), Brunauer Emmett-Teller (BET), X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscope (SEM)/ High-resolution Transmission Electron Microscopy (HRTEM), UV vis Diffuse Reflectance Spectra (DRS) and Photoluminescence (PL). Meanwhile, the photocatalytic properties of the catalysts were determined for diclofenac sodium (DS) degradation and the photocatalytic mechanism was also explored. The results indicate that both of the two kinds of CuBi2O4/Ag3PO4 exhibit higher photocatalytic efficiency, mineralization rate, and stability than that of pure CuBi2O4 or Ag3PO4. Moreover, the catalytic activity of CuBi2O4/Ag3PO4 can be further enhanced by adding H2O2. The free radical capture experiments show that in the pure CuBi2O4/Ag3PO4 photocatalytic system, the OH* and O2*- are the main species participating in DS degradation; however, in the CuBi2O4/Ag3PO4 photocatalytic system with H2O2, all OH*, h+, and O2*- take part in the DS degradation, and the contribution order is OH* > h+ > O2*-. Accordingly, the photocatalytic mechanism of CuBi2O4/Ag3PO4 could be explained by the Z-Scheme theory, while the catalysis of CuBi2O4/Ag3PO4 with H2O2 follows the heterojunction energy band theory.

AB - In recent years, the in ovo feeding in fertilized broiler (Gallus gallus) eggs approach was further developed and currently is widely applied in the evaluation process of the effects of functional foods (primarily plant origin compounds) on the functionality of the intestinal brush border membrane, as well as potential prebiotic properties and interactions with the intestinal microbial populations. This review collates the information of potential nutrients and their effects on the mineral absorption, gut development, brush border membrane functionality, and immune system. In addition, the advantages and limitations of the in ovo feeding method in the assessment of potential prebiotic effects of plant origin compounds is discussed. PMID- 29597268 TI - Antibacterial and Barrier Properties of Gelatin Coated by Electrospun Polycaprolactone Ultrathin Fibers Containing Black Pepper Oleoresin of Interest in Active Food Biopackaging Applications. AB - The present study evaluated the effect of using electrospun polycaprolactone (PCL) as a barrier coating and black pepper oleoresin (OR) as a natural extract on the morphology, thermal, mechanical, antimicrobial, oxygen, and water vapor barrier properties of solvent cast gelatin (GEL). The antimicrobial activity of the developed multilayer system obtained by the so-called electrospinning coating technique was also evaluated against Staphylococcus aureus strains for 10 days. The results showed that the multilayer system containing PCL and OR increased the thermal resistance, elongated the GEL film, and significantly diminished its permeance to water vapor. Active multilayer systems stored in hermetically closed bottles increased their antimicrobial activity after 10 days by inhibiting the growth of Staphylococcus aureus. This study demonstrates that addition of electrospun PCL ultrathin fibers and OR improved the properties of GEL films, which promoted its potential use in active food packaging applications. PMID- 29597269 TI - Novel Water Soluble Chitosan Derivatives with 1,2,3-Triazolium and Their Free Radical-Scavenging Activity. AB - Chitosan is an abundant and renewable polysaccharide, which exhibits attractive bioactivities and natural properties. Improvement such as chemical modification of chitosan is often performed for its potential of providing high bioactivity and good water solubility. A new class of chitosan derivatives possessing 1,2,3 triazolium charged units by associating "click reaction" with efficient 1,2,3 triazole quaternization were designed and synthesized. Their free radical scavenging activity against three free radicals was tested. The inhibitory property and water solubility of the synthesized chitosan derivatives exhibited a remarkable improvement over chitosan. It is hypothesized that triazole or triazolium groups enable the synthesized chitosan to possess obviously better radical-scavenging activity. Moreover, the scavenging activity against superoxide radical of chitosan derivatives with triazolium (IC50 < 0.01 mg mL-1) was more efficient than that of derivatives with triazole and Vitamin C. In the 1,1 diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radical-scavenging assay, the same pattern were observed, which should be related to the triazolium grafted at the periphery of molecular chains. PMID- 29597270 TI - Prediction of Tibial Rotation Pathologies Using Particle Swarm Optimization and K Means Algorithms. AB - The aim of this article is to investigate pathological subjects from a population through different physical factors. To achieve this, particle swarm optimization (PSO) and K-means (KM) clustering algorithms have been combined (PSO-KM). Datasets provided by the literature were divided into three clusters based on age and weight parameters and each one of right tibial external rotation (RTER), right tibial internal rotation (RTIR), left tibial external rotation (LTER), and left tibial internal rotation (LTIR) values were divided into three types as Type 1, Type 2 and Type 3 (Type 2 is non-pathological (normal) and the other two types are pathological (abnormal)), respectively. The rotation values of every subject in any cluster were noted. Then the algorithm was run and the produced values were also considered. The values of the produced algorithm, the PSO-KM, have been compared with the real values. The hybrid PSO-KM algorithm has been very successful on the optimal clustering of the tibial rotation types through the physical criteria. In this investigation, Type 2 (pathological subjects) is of especially high predictability and the PSO-KM algorithm has been very successful as an operation system for clustering and optimizing the tibial motion data assessments. These research findings are expected to be very useful for health providers, such as physiotherapists, orthopedists, and so on, in which this consequence may help clinicians to appropriately designing proper treatment schedules for patients.

AB - Compound libraries are important requirement in target-based drug discovery. In the present work, a small focused compound library based on beta-aminoketone scaffold has been prepared combining microwave-assisted organic synthesis (MAOS) with polymer-assisted solution phase synthesis (PASPS) and replacing reaction workup standard purification procedures with solid phase extraction (SPE). Specifically, the effects of solvent, such as dioxane, dimethylformamide (DMF), polyethylene glycol 400 (PEG 400), temperature, irradiation time, stoichiometric ratio of reagents, and catalysts (HCl, acetic acid, cerium ammonium nitrate (CAN)) were investigated to maximize both conversion and yield. The optimized protocol generally afforded the desired products in satisfying yields and purities. The designed library is a part of our current research on sigma 1 receptor modulators, a valuable tool for the identification of novel potential hit compounds. PMID- 29597272 TI - A Potential Adjuvant Agent of Chemotherapy: Sepia Ink Polysaccharides. AB - Sepia ink polysaccharide (SIP) isolated from squid and cuttlefish ink is a kind of acid mucopolysaccharide that has been identified in three types of primary structures from squid (Illex argentinus and Ommastrephes bartrami), cuttlefish Sepiella maindroni, and cuttlefish Sepia esculenta ink. Although SIP has been proved to be multifaceted, most of the reported evidence has illuminated its chemopreventive and antineoplastic activities. As a natural product playing a role in cancer treatment, SIP may be used as chemotherapeutic ancillary agent or functional food. Based on the current findings on SIP, we have summarized four topics in this review, including: chemopreventive, antineoplastic, chemosensitive, and procoagulant and anticoagulant activities, which are correlative closely with the actions of anticancer agents on cancer patients, such as anticancer, toxicity and thrombogenesis, with the latter two actions being common causes of death in cancer cases exposed to chemotherapeutic agents. PMID- 29597274 TI - Human Mitochondrial HMG-CoA Synthase Deficiency: Role of Enzyme Dimerization Surface and Characterization of Three New Patients. AB - Mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase deficiency (mitochondrial HMG-CoA synthase deficiency or mHS deficiency, OMIM #605911) is an inborn error of metabolism that affects ketone body synthesis. Acute episodes include vomiting, lethargy, hepatomegaly, hypoglycemia and dicarboxylic aciduria. The diagnosis is difficult due to the relatively unspecific clinical and biochemical presentation, and fewer than 30 patients have been described. This work describes three new patients with mHS deficiency and two missense mutations c.334C>T (p.R112W) and c.430G>T (p.V144L) previously not reported. We developed a new method to express and measure the activity of the enzyme and in this work the study is extended to ten new missense variants including those of our patients. Enzymatic assays showed that three of the mutant proteins retained some but seven completely lacked activity. The identification of a patient homozygous for a mutation that retains 70% of enzyme activity opens the door to a new interpretation of the disease by demonstrating that a modest impairment of enzyme function can actually produce symptoms. This is also the first study employing molecular dynamics modelling of the enzyme mutations. We show that the correct maintenance of the dimerization surface is crucial for retaining the structure of the active center and therefore the activity of the enzyme. PMID- 29597275 TI - Graphene Quantum Dots-ZnS Nanocomposites with Improved Photoelectric Performances. AB - ZnS-graphene quantum dot (GQDs) composites were synthesized by a simple solvothermal method, in which GQDs were prepared by a hydrothermal cutting process. The products were characterized by transmission electron microscopy, atomic force microscopy, X-ray diffraction and ultraviolet-visible absorption spectroscopy. The results show that GQDs were obtained by size tailoring of 1-4 graphene layers and combined with cubic ZnS nanoparticles to form ZnS-GQDs composites. The photocurrent and electrochemical behavior of the products were evaluated by transient photocurrent responses and electrochemical impedance spectra. The photocurrent density of ZnS-GQDs achieves the value of 2.32 * 10-5 A/cm2, which is 2.4-times as high as that of ZnS-graphene. GQDs serve as an electrical conducting material, which decreases the conductive path and accelerates the electron transfer. The charge-transfer resistance of ZnS-GQDs is much lower than that of ZnS-graphene and pure ZnS due to the effective electron separation and transfer ability upon the incorporation of GQDs. PMID- 29597273 TI - Nutrition-Related Knowledge, Attitudes, and Practices (KAP) among Kindergarten Teachers in Chongqing, China: A Cross-Sectional Survey. AB - Kindergarten teachers play an important role in providing kindergarten children with education on nutrition. However, few studies have been published on nutrition-related knowledge, attitudes, and practices (KAP) of Chinese kindergarten teachers. This study aimed to assess the nutrition-related knowledge, attitudes, and practices (KAP) of kindergarten teachers in Chongqing, China. Thus, a cross-sectional survey was conducted using a structured KAP model questionnaire administered to 222 kindergarten teachers, who were senior teachers from 80 kindergartens in 19 districts and 20 counties in Chongqing. Multiple regression analysis was used to analyze the influential factors. Among the participants, 54.2% were familiar with simple nutrition-related knowledge; only 9.9% of them were satisfied with their knowledge of childhood nutrition; and 97.7% of them had a positive attitude to learn nutrition-related knowledge. Only 38.7% of the participants had attended pediatric nutrition knowledge courses or training. Multiple regression analysis confirmed significant independent effects on the nutrition knowledge score (p < 0.0001) of respondents on age, type of residence, type of kindergarten, body mass index(BMI), professional training of kindergarten teachers, behavior of having ever participated in childhood nutrition education knowledge courses or training, and behavior of having ever paid attention to children's nutrition knowledge. The model indicated that independent variables explained 45.4% (adjusted R2) of the variance found in the knowledge scores of respondents. While there were low levels of nutrition knowledge and training, it was still encouraging to note that there were positive attitudes towards acquiring nutrition-related knowledge among kindergarten teachers in Chongqing, China. These findings provide some implications that necessary training measures need to be carried out to improve the nutrition related knowledge level among kindergarten teachers in China. PMID- 29597276 TI - Linear Feature Projection-Based Sensory Event Detection from the Multiunit Activity of Dorsal Root Ganglion Recordings. AB - Afferent signals recorded from the dorsal root ganglion can be used to extract sensory information to provide feedback signals in a functional electrical stimulation (FES) system. The goal of this study was to propose an efficient feature projection method for detecting sensory events from multiunit activity based feature vectors of tactile afferent activity. Tactile afferent signals were recorded from the L4 dorsal root ganglion using a multichannel microelectrode for three types of sensory events generated by mechanical stimulation on the rat hind paw. The multiunit spikes (MUSs) were extracted as multiunit activity-based feature vectors and projected using a linear feature projection method which consisted of projection pursuit and negentropy maximization (PP/NEM). Finally, a multilayer perceptron classifier was used to detect sensory events. The proposed method showed a detection accuracy superior to those of other linear and nonlinear feature projection methods and all processes were completed within real time constraints. Results suggest that the proposed method could be useful to detect sensory events in real time. We have demonstrated the methodology for an efficient feature projection method to detect real-time sensory events from the multiunit activity of dorsal root ganglion recordings. The proposed method could be applied to provide real-time sensory feedback signals in closed-loop FES systems. PMID- 29597277 TI - Potential of Silicon Amendment for Improved Wheat Production. AB - Many studies throughout the world have shown positive responses of various crops to silicon (Si) application in terms of plant health, nutrient uptake, yield, and quality. Although not considered an essential element for plant growth, Si has been recently recognized as a "beneficial substance" or "quasi-essential" due to its important role in plant nutrition, especially notable under stressed conditions. The goal of this study was to evaluate the effect of Si on wheat plant height, grain yield (GY), and grain protein content (GP). The experiment was conducted during two consecutive growing seasons in Idaho. A split-plot experimental design was used with three Si fertilization rates (140, 280, and 560 kg Si ha-1) corresponding to 100, 50, and 25% of manufacturer-recommended rates and two application times-at planting and tillering (Feekes 5). MontanaGrowTM (0 0-5) by MontanaGrow Inc. (Bonner, MT, USA) used in this study is a Si product sourced from a high-energy amorphous (non-crystalized) volcanic tuff. There was no significant effect of Si rate and application time on plant height, nutrient uptake, GY, or GP of irrigated winter wheat grown in non-stressed conditions. These results could be directly related to the Si fertilizer source used in the study. We are planning to further evaluate Si's effect on growth and grain production of wheat grown in non-stressed vs. stressed conditions utilizing several different Si sources and application methods. PMID- 29597278 TI - Ratcheting Strain and Microstructure Evolution of AZ31B Magnesium Alloy under a Tensile-Tensile Cyclic Loading. AB - In this paper, studies were conducted to investigate the deformation behavior and microstructure change in a hot-rolled AZ31B magnesium alloy during a tensile tensile cyclic loading. The relationship between ratcheting effect and microstructure change was discussed. The ratcheting effect in the material during current tensile-tensile fatigue loading exceeds the material's fatigue limit and the development of ratcheting strain in the material experienced three stages: initial sharp increase stage (Stage I); steady stage (Stage II); and final abrupt increase stage (Stage III). Microstructure changes in Stage I and Stage II are mainly caused by activation of basal slip system. The Extra Geometrically Necessary Dislocations (GNDs) were also calculated to discuss the relationship between the dislocation caused by the basal slip system and the ratcheting strain during the cyclic loading. In Stage III, both the basal slip and the {11-20} twins are found active during the crack propagation. The fatigue crack initiation in the AZ31B magnesium alloy is found due to the basal slip and the {11-20} tensile twins. PMID- 29597280 TI - A Sparsity-Promoted Method Based on Majorization-Minimization for Weak Fault Feature Enhancement. AB - Fault transient impulses induced by faulty components in rotating machinery usually contain substantial interference. Fault features are comparatively weak in the initial fault stage, which renders fault diagnosis more difficult. In this case, a sparse representation method based on the Majorzation-Minimization (MM) algorithm is proposed to enhance weak fault features and extract the features from strong background noise. However, the traditional MM algorithm suffers from two issues, which are the choice of sparse basis and complicated calculations. To address these challenges, a modified MM algorithm is proposed in which a sparse optimization objective function is designed firstly. Inspired by the Basis Pursuit (BP) model, the optimization function integrates an impulsive feature preserving factor and a penalty function factor. Second, a modified Majorization iterative method is applied to address the convex optimization problem of the designed function. A series of sparse coefficients can be achieved through iterating, which only contain transient components. It is noteworthy that there is no need to select the sparse basis in the proposed iterative method because it is fixed as a unit matrix. Then the reconstruction step is omitted, which can significantly increase detection efficiency. Eventually, envelope analysis of the sparse coefficients is performed to extract weak fault features. Simulated and experimental signals including bearings and gearboxes are employed to validate the effectiveness of the proposed method. In addition, comparisons are made to prove that the proposed method outperforms the traditional MM algorithm in terms of detection results and efficiency. PMID- 29597279 TI - The Hippo Pathway: Immunity and Cancer. AB - Since its discovery, the Hippo pathway has emerged as a central signaling network in mammalian cells. Canonical signaling through the Hippo pathway core components (MST1/2, LATS1/2, YAP and TAZ) is important for development and tissue homeostasis while aberrant signaling through the Hippo pathway has been implicated in multiple pathologies, including cancer. Recent studies have uncovered new roles for the Hippo pathway in immunology. In this review, we summarize the mechanisms by which Hippo signaling in pathogen-infected or neoplastic cells affects the activities of immune cells that respond to these threats. We further discuss how Hippo signaling functions as part of an immune response. Finally, we review how immune cell-intrinsic Hippo signaling modulates the development/function of leukocytes and propose directions for future work. PMID- 29597281 TI - Evaluating Muscle Activation Models for Elbow Motion Estimation. AB - Adoption of wearable assistive technologies relies heavily on improvement of existing control system models. Knowing which models to use and how to improve them is difficult to determine due to the number of proposed solutions with relatively little broad comparisons. One type of these models, muscle activation models, describes the nonlinear relationship between neural inputs and mechanical activation of the muscle. Many muscle activation models can be found in the literature, but no comparison is available to guide the community on limitations and improvements. In this research, an EMG-driven elbow motion model is developed for the purpose of evaluating muscle activation models. Seven muscle activation models are used in an optimization procedure to determine which model has the best performance. Root mean square errors in muscle torque estimation range from 1.67-2.19 Nm on average over varying input trajectories. The computational resource demand was also measured during the optimization procedure, as it is an important aspect for determining if a model is feasible for use in a particular wearable assistive device. This study provides insight into the ability of these models to estimate elbow motion and the trade-off between estimation accuracy and computational demand. PMID- 29597283 TI - Individual Biometric Identification Using Multi-Cycle Electrocardiographic Waveform Patterns. AB - The electrocardiogram (ECG) waveform conveys information regarding the electrical property of the heart. The patterns vary depending on the individual heart characteristics. ECG features can be potentially used for biometric recognition. This study presents a new method using the entire ECG waveform pattern for matching and demonstrates that the approach can potentially be employed for individual biometric identification. Multi-cycle ECG signals were assessed using an ECG measuring circuit, and three electrodes can be patched on the wrists or fingers for considering various measurements. For biometric identification, our fold cross validation was used in the experiments for assessing how the results of a statistical analysis will generalize to an independent data set. Four different pattern matching algorithms, i.e., cosine similarity, cross correlation, city block distance, and Euclidean distances, were tested to compare the individual identification performances with a single channel of ECG signal (3 wire ECG). To evaluate the pattern matching for biometric identification, the ECG recordings for each subject were partitioned into training and test set. The suggested method obtained a maximum performance of 89.9% accuracy with two heartbeats of ECG signals measured on the wrist and 93.3% accuracy with three heartbeats for 55 subjects. The performance rate with ECG signals measured on the fingers improved up to 99.3% with two heartbeats and 100% with three heartbeats of signals for 20 subjects. PMID- 29597282 TI - Identification of Leaf Promoters for Use in Transgenic Wheat. AB - Wheat yields have plateaued in recent years and given the growing global population there is a pressing need to develop higher yielding varieties to meet future demand. Genetic manipulation of photosynthesis in elite wheat varieties offers the opportunity to significantly increase yields. However, the absence of a well-defined molecular tool-box of promoters to manipulate leaf processes in wheat hinders advancements in this area. Two promoters, one driving the expression of sedoheptulose-1,7-bisphosphatase (SBPase) and the other fructose 1,6-bisphosphate aldolase (FBPA) from Brachypodium distachyon were identified and cloned into a vector in front of the GUS reporter gene. Both promoters were shown to be functionally active in wheat in both transient assays and in stably transformed wheat plants. Analysis of the stable transformants of wheat (cv. Cadenza) showed that both promoters controlled gus expression throughout leaf development as well as in other green tissues. The availability of these promoters provides new tools for the expression of genes in transgenic wheat leaves and also paves the way for multigene manipulation of photosynthesis to improve yields. PMID- 29597284 TI - PSPICE Hybrid Modeling and Simulation of Capacitive Micro-Gyroscopes. AB - With an aim to reduce the cost of prototype development, this paper establishes a PSPICE hybrid model for the simulation of capacitive microelectromechanical systems (MEMS) gyroscopes. This is achieved by modeling gyroscopes in different modules, then connecting them in accordance with the corresponding principle diagram. Systematic simulations of this model are implemented along with a consideration of details of MEMS gyroscopes, including a capacitance model without approximation, mechanical thermal noise, and the effect of ambient temperature. The temperature compensation scheme and optimization of interface circuits are achieved based on the hybrid closed-loop simulation of MEMS gyroscopes. The simulation results show that the final output voltage is proportional to the angular rate input, which verifies the validity of this model. PMID- 29597285 TI - A Novel GMM-Based Behavioral Modeling Approach for Smartwatch-Based Driver Authentication. AB - All drivers have their own distinct driving habits, and usually hold and operate the steering wheel differently in different driving scenarios. In this study, we proposed a novel Gaussian mixture model (GMM)-based method that can improve the traditional GMM in modeling driving behavior. This new method can be applied to build a better driver authentication system based on the accelerometer and orientation sensor of a smartwatch. To demonstrate the feasibility of the proposed method, we created an experimental system that analyzes driving behavior using the built-in sensors of a smartwatch. The experimental results for driver authentication-an equal error rate (EER) of 4.62% in the simulated environment and an EER of 7.86% in the real-traffic environment-confirm the feasibility of this approach. PMID- 29597286 TI - A Large-Scale Study of Fingerprint Matching Systems for Sensor Interoperability Problem. AB - The fingerprint is a commonly used biometric modality that is widely employed for authentication by law enforcement agencies and commercial applications. The designs of existing fingerprint matching methods are based on the hypothesis that the same sensor is used to capture fingerprints during enrollment and verification. Advances in fingerprint sensor technology have raised the question about the usability of current methods when different sensors are employed for enrollment and verification; this is a fingerprint sensor interoperability problem. To provide insight into this problem and assess the status of state-of the-art matching methods to tackle this problem, we first analyze the characteristics of fingerprints captured with different sensors, which makes cross-sensor matching a challenging problem. We demonstrate the importance of fingerprint enhancement methods for cross-sensor matching. Finally, we conduct a comparative study of state-of-the-art fingerprint recognition methods and provide insight into their abilities to address this problem. We performed experiments using a public database (FingerPass) that contains nine datasets captured with different sensors. We analyzed the effects of different sensors and found that cross-sensor matching performance deteriorates when different sensors are used for enrollment and verification. In view of our analysis, we propose future research directions for this problem.

AB - C-Maf Inducing Protein (CMIP) gene polymorphisms were reported to be associated with type 2 diabetes mellitus (T2DM). Whether the association between CMIP and T2DM is mediated via obesity-related phenotypes is still unclear. We analyzed the association of CMIP rs2925979 with T2DM and a comprehensive set of obesity related phenotypes in 1576 families ascertained from a Chinese population. These families included a total of 3444 siblings (1582 with T2DM, 963 with prediabetes, and 899 with a normal glucose level). Using multi-level mixed effects regression models, we found that each copy of CMIP rs2925979_T allele was associated with a 29% higher risk of T2DM in females (p = 9.30 * 10-4), while it was not significantly associated with T2DM in males (p = 0.705). Meanwhile, rs2925979_T allele was associated with lower levels of body mass index (BMI), waist circumference (WC), hip circumference (HC), percentage of body fat (PBF), PBF of arms, PBF of legs, and PBF of trunk in nondiabetes females (all p < 0.05). The opposite associations of rs2925979_T allele with T2DM and obesity-related phenotypes suggest that CMIP may exert independent pleiotropic effects on T2DM and obesity-related phenotypes in females.

AB - Amine groups play significant roles in polymeric composites for heavy metals removal. However, generating a composite with a large number of functional and stable amine groups based on clay is still a challenge. In this work, a new amine functionalized adsorbent based on acid-activated vermiculite (a-Verm) was prepared by organic modification of silane coupling agent as bridge, followed by in situ polymerization of acrylamide (AM) and further grafting of triethylene tetramine (TETA). The obtained polymeric composite g-PAM/OVerm was characterized by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), Fourier transform infrared (FTIR), thermal analysis (TG/DTG), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) analyses, confirming that amine groups were successfully grafted onto the surface of Verm. The efficacy g PAM/OVerm for removing Pb(II) was tested. The adsorption equilibrium data on g PAM/OVerm was in good accordance with the Langmuir adsorption isotherms, and the adsorption maximal value of Pb(II) was 219.4 mg.g-1. The adsorption kinetic data fit the pseudo-second-order kinetic model well. Additionally, g-PAM/OVerm has better selectivity for Pb(II) ion in comparison with Zn(II), Cd(II) and Cu(II) ions. The present work shows that g-PAM/OVerm holds great potential for removing Pb(II) from wastewater, and provides a new and efficient method for the removal of heavy metal ions from industrial wastewater. PMID- 29597289 TI - The Epidemiology of Unintentional and Violence-Related Injury Morbidity and Mortality among Children and Adolescents in the United States. AB - Injuries and violence among young people have a substantial emotional, physical, and economic toll on society. Understanding the epidemiology of this public health problem can guide prevention efforts, help identify and reduce risk factors, and promote protective factors. We examined fatal and nonfatal unintentional injuries, injuries intentionally inflicted by other (i.e., assaults and homicides) among children ages 0-19, and intentionally self-inflicted injuries (i.e., self-harm and suicides) among children ages 10-19. We accessed deaths (1999-2015) and visits to emergency departments (2001-2015) for these age groups through the Centers for Disease Control and Prevention's (CDC) Web-based Injury Statistics Query and Reporting System (WISQARS), and examined trends and differences by age, sex, race/ethnicity, rural/urban status, and injury mechanism. Almost 13,000 children and adolescents age 0-19 years died in 2015 from injury and violence compared to over 17,000 in 1999. While the overall number of deaths has decreased over time, there were increases in death rates among certain age groups for some categories of unintentional injury and for suicides. The leading causes of injury varied by age group. Our results indicate that efforts to reduce injuries to children and adolescents should consider cause, intent, age, sex, race, and regional factors to assure that prevention resources are directed at those at greatest risk. PMID- 29597290 TI - Genome-Wide Identification of the Alba Gene Family in Plants and Stress Responsive Expression of the Rice Alba Genes. AB - Architectural proteins play key roles in genome construction and regulate the expression of many genes, albeit the modulation of genome plasticity by these proteins is largely unknown. A critical screening of the architectural proteins in five crop species, viz., Oryza sativa, Zea mays, Sorghum bicolor, Cicer arietinum, and Vitis vinifera, and in the model plant Arabidopsis thaliana along with evolutionary relevant species such as Chlamydomonas reinhardtii, Physcomitrella patens, and Amborella trichopoda, revealed 9, 20, 10, 7, 7, 6, 1, 4, and 4 Alba (acetylation lowers binding affinity) genes, respectively. A phylogenetic analysis of the genes and of their counterparts in other plant species indicated evolutionary conservation and diversification. In each group, the structural components of the genes and motifs showed significant conservation. The chromosomal location of the Alba genes of rice (OsAlba), showed an unequal distribution on 8 of its 12 chromosomes. The expression profiles of the OsAlba genes indicated a distinct tissue-specific expression in the seedling, vegetative, and reproductive stages. The quantitative real-time PCR (qRT-PCR) analysis of the OsAlba genes confirmed their stress-inducible expression under multivariate environmental conditions and phytohormone treatments. The evaluation of the regulatory elements in 68 Alba genes from the 9 species studied led to the identification of conserved motifs and overlapping microRNA (miRNA) target sites, suggesting the conservation of their function in related proteins and a divergence in their biological roles across species. The 3D structure and the prediction of putative ligands and their binding sites for OsAlba proteins offered a key insight into the structure-function relationship. These results provide a comprehensive overview of the subtle genetic diversification of the OsAlba genes, which will help in elucidating their functional role in plants. PMID- 29597291 TI - Antiviral and Inflammatory Cellular Signaling Associated with Enterovirus 71 Infection. AB - Enterovirus 71 (EV71) infection has become a major threat to global public health, especially in infants and young children. Epidemiological studies have indicated that EV71 infection is responsible for severe and even fatal cases of hand, foot, and mouth disease (HFMD). Accumulated evidence indicates that EV71 infection triggers a plethora of interactive signaling pathways, resulting in host immune evasion and inflammatory response. This review mainly covers the effects of EV71 infection on major antiviral and inflammatory cellular signal pathways. EV71 can activate cellular signaling networks including multiple cell surface and intracellular receptors, intracellular kinases, calcium flux, and transcription factors that regulate antiviral innate immunity and inflammatory response. Cellular signaling plays a critical role in the regulation of host innate immune and inflammatory pathogenesis. Elucidation of antiviral and inflammatory cellular signaling pathways initiated by EV71 will not only help uncover the potential mechanisms of EV71 infection-induced pathogenesis, but will also provide clues for the design of therapeutic strategies against EV71 infection. PMID- 29597292 TI - Comparison of Commensal Escherichia coli Isolates from Adults and Young Children in Lubuskie Province, Poland: Virulence Potential, Phylogeny and Antimicrobial Resistance. AB - Commensal Escherichia coli population is a dynamic structure which may be important in the pathogenesis of extraintestinal infections. The aim of this study was the comparison of genetic diversity of commensal E. coli isolates from two age group-adults and young children. E. coli strains were isolated on MacConkey agar and identified by biochemical tests. Determination of four major phylogenetic groups, identification of virulence genes and antimicrobial resistance determinants were performed by using multiplex or simplex PCR. Phenotypic analysis of resistance was based on disc-diffusion method. The prevalence of virulence genes was significantly higher among isolates from adults than from young children. Phylogroup B2 predominated among E. coli from adults, whereas phylogroup A was the most common in isolates from young children. The analyses of antimicrobial resistance revealed that resistance to at least one antimicrobial agent and multidrug-resistance were detected significantly more frequent in the isolates from adults than from young children. This study documented that the commensal E. coli isolates from adults showed greater genetic diversity than from young children and constitutes a substantial reservoir of the virulence genes typical for extraintestinal pathogenic E. coli. PMID- 29597293 TI - Transcriptome Analysis Reveals Molecular Signatures of Luteoloside Accumulation in Senescing Leaves of Lonicera macranthoides. AB - Lonicera macranthoides is an important medicinal plant widely used in traditional Chinese medicine. Luteoloside is a critical bioactive compound in L. macranthoides. To date, the molecular mechanisms underlying luteoloside biosynthesis are still largely unknown. In this work, high performance liquid chromatography (HPLC) was employed to determine the luteoloside contents in leaves, stems, and flowers at different developmental stages. Results showed that senescing leaves can accumulate large amounts of luteoloside, extremely higher than that in young and semi-lignified leaves and other tissues. RNA-Seq analysis identified that twenty-four differentially expressed unigenes (DEGs) associated with luteoloside biosynthesis were significantly up-regulated in senescing leaves, which are positively correlated with luteoloside accumulation. These DEGs include phenylalanine ammonia lyase 2, cinnamate 4-hydroxylase 2, thirteen 4 coumarate-CoA ligases, chalcone synthase 2, six flavonoid 3'-monooxygenase (F3'H) and two flavone 7-O-beta-glucosyltransferase (UFGT) genes. Further analysis demonstrated that two F3'Hs (CL11828.Contig1 and CL11828.Contig2) and two UFGTs (Unigene2918 and Unigene97915) might play vital roles in luteoloside generation. Furthermore, several transcription factors (TFs) related to flavonoid biosynthesis including MYB, bHLH and WD40, were differentially expressed during leaf senescence. Among these TFs, MYB12, MYB75, bHLH113 and TTG1 were considered to be key factors involved in the regulation of luteoloside biosynthesis. These findings provide insights for elucidating the molecular signatures of luteoloside accumulation in L. macranthoides. PMID- 29597294 TI - Engineering the Salt-Inducible Ectoine Promoter Region of Halomonas elongata for Protein Expression in a Unique Stabilizing Environment. AB - It has been firmly established that organic osmolytes (compatible solutes) of halophilic Bacteria and Archaea have positive effects on conformation and activity of proteins, and may therefore improve their functional production. In particular, the amino acid derivative ectoine is known for its conformational stabilization, aggregation suppression, and radical protection properties. The natural producer and industrial production strain Halomonas elongata accumulates ectoine in the cytoplasm, and as a result offers a unique stabilizing environment for recombinant proteins. For the construction of broad hoast range vector systems with fluorescent reporter proteins, we chose the salt-inducible promoter region of the ectoine gene cluster (promA). A closer inspection of the genetic background revealed that its combination of sigma 38 (sigma38) and sigma 70 (sigma70) promoters was followed by a weak ribosomal binding site (RBS). This inspired a systematic approach for the construction of a promA-based vector series with a synthetic RBS region using the RBS Calculator v2.0, which resulted in a greatly improved salt-dependent expression-even in a deletion construct lacking the sigma38 promoter. To expand the application range of this expression system, we looked further into the possible export of recombinant proteins into the periplasm. Both sec and tat leader sequences from H. elongata proved to be suitable for directed periplasmic transport into an extreme environment of freely selectable ionic strength. PMID- 29597295 TI - Functionalized Gold Nanoparticles for the Detection of C-Reactive Protein. AB - C-reactive protein (CRP) is a very important biomarker of infection and inflammation for a number of diseases. Routine CRP measurements with high sensitivity and reliability are highly relevant to the assessment of states of inflammation and the efficacy of treatment intervention, and require the development of very sensitive, selective, fast, robust and reproducible assays. Gold nanoparticles (Au NPs) are distinguished for their unique electrical and optical properties and the ability to conjugate with biomolecules. Au NP-based probes have attracted considerable attention in the last decade in the analysis of biological samples due to their simplicity, high sensitivity and selectivity. Thus, this article aims to be a critical and constructive analysis of the literature of the last three years regarding the advances made in the development of bioanalytical assays based on gold nanoparticles for the in vitro detection and quantification of C-reactive protein from biological samples. Current methods for Au NP synthesis and the strategies for surface modification aiming at selectivity towards CRP are highlighted. PMID- 29597296 TI - Silkworm Pupa Protein Hydrolysate Induces Mitochondria-Dependent Apoptosis and S Phase Cell Cycle Arrest in Human Gastric Cancer SGC-7901 Cells. AB - Silkworm pupae (Bombyx mori) are a high-protein nutrition source consumed in China since more than 2 thousand years ago. Recent studies revealed that silkworm pupae have therapeutic benefits to treat many diseases. However, the ability of the compounds of silkworm pupae to inhibit tumourigenesis remains to be elucidated. Here, we separated the protein of silkworm pupae and performed alcalase hydrolysis. Silkworm pupa protein hydrolysate (SPPH) can specifically inhibit the proliferation and provoke abnormal morphologic features of human gastric cancer cells SGC-7901 in a dose- and time-dependent manner. Moreover, flow cytometry indicated that SPPH can induce apoptosis and arrest the cell-cycle in S phase. Furthermore, SPPH was shown to provoke accumulation of reactive oxygen species (ROS) and depolarization of mitochondrial membrane potential. Western blotting analysis indicated that SPPH inhibited Bcl-2 expression and promoted Bax expression, and subsequently induced apoptosis-inducing factor and cytochrome C release, which led to the activation of initiator caspase-9 and executioner caspase-3, cleavage of poly (ADP-ribose) polymerase (PARP), eventually caused cell apoptosis. Moreover, SPPH-induced S-phase arrest was mediated by up-regulating the expression of E2F1 and down-regulating those of cyclin E, CDK2 and cyclin A2. Transcriptome sequencing and gene set enrichment analysis (GSEA) also revealed that SPPH treatment could affect gene expression and pathway regulation related to tumourigenesis, apoptosis and cell cycle. In summary, our results suggest that SPPH could specifically suppress cell growth of SGC-7901 through an intrinsic apoptotic pathway, ROS accumulation and cell cycle arrest, and silkworm pupae have a potential to become a source of anticancer agents in the future. PMID- 29597297 TI - Parents' Experiences of Suicide-Bereavement: A Qualitative Study at 6 and 12 Months after Loss. AB - The death of a child by suicide is a severe trauma, placing parents at greater risk of psychological morbidity and physical health problems compared to other causes of death. However, few studies have examined the aftermath and bereavement experience for parents following the death of a child to suicide, limiting the ability to guide effective postvention services through empirical research. The current study, which was part of a larger longitudinal investigation of suicide bereavement in Queensland, Australia, examined the individual experiences of both mothers and fathers bereaved by suicide over time, specifically at the six month and 12 month time points after their loss. Bereaved parents who had provided written consent to be contacted for research purposes were identified through the Queensland Suicide Register, and took part in individual, semi-structured interviews. Generic qualitative analysis identified three key themes: searching for answers and sense-making, coping strategies and support, and finding meaning and purpose. Some participants showed indications of meaning-making and post traumatic growth at 12 months after the suicide. According to the dual process model of bereavement, it is likely that participants were still oscillating between sense-making and meaning making, indicating that adapting to bereavement is a dynamic and fluctuating process. PMID- 29597298 TI - Probing Interactions between AuNPs/AgNPs and Giant Unilamellar Vesicles (GUVs) Using Hyperspectral Dark-field Microscopy. AB - Noble metallic nanoparticles (NPs) such as gold and silver nanoparticles (AuNPs and AgNPs) have been shown to exhibit anti-tumor effect in anti-angiogenesis, photothermal and radio therapeutics. On the other hand, cell membranes are critical locales for specific targeting of cancerous cells. Therefore, NP membrane interactions need be studied at molecular level to help better understand the underlying physicochemical mechanisms for future applications in cancer nanotechnology. Herein, we report our study on the interactions between citrate stabilized colloidal AuNPs/AgNPs (10 nm in size) and giant unilamellar vesicles (GUVs) using hyperspectral dark-field microscopy. GUVs are large model vesicle systems well established for the study of membrane dynamics. GUVs used in this study were prepared with dimyristoyl phosphatidylcholine (DMPC) and doped with cholesterol at various molar concentrations. Both imaging and spectral results support that AuNPs and AgNPs interact very differently with GUVs, i.e., AuNPs tend to integrate in between the lipid bilayer and form a uniform golden brown crust on vesicles, whereas AgNPs are bejeweled on the vesicle surface as isolated particles or clusters with much varied configurations. The more disruptive capability of AuNPs is hypothesized to be responsible for the formation of golden brown crusts in AuNP-GUV interaction. GUVs of 20 mol% CHOL:DMPC were found to be a most economical concentration for GUVs to achieve the best integrity and the least permeability, consistent with the finding from other phase studies of lipid mixture that the liquid-ordered domains have the largest area fraction of the entire membrane at around 20 mol% of cholesterol. PMID- 29597299 TI - Synthesis and Antiproliferative Activity of Minor Hops Prenylflavonoids and New Insights on Prenyl Group Cyclization. AB - Synthesis of minor prenylflavonoids found in hops and their non-natural derivatives were performed. The antiproliferative activity of the obtained compounds against some human cancer cell lines was investigated. Using xanthohumol isolated from spent hops as a lead compound, a series of minor hop prenylflavonoids and synthetic derivatives were obtained by isomerization, cyclisation, oxidative-cyclisation, oxidation, reduction and demethylation reactions. Three human cancer cell lines-breast (MCF-7), prostate (PC-3) and colon (HT-29)-were used in antiproliferative assays, with cisplatin as a control compound. Five minor hop prenyl flavonoids and nine non-natural derivatives of xanthohumol have been synthetized. Syntheses of xanthohumol K, its dihydro- and tetrahydro-derivatives and 1",2",alpha,beta-tetrahydroxanthohumol C were described for the first time. All of the minor hops prenyl flavonoids exhibited strong to moderate antiproliferative activity in vitro. The minor hops flavonoids xanthohumol C and 1",2"-dihydroxanthohumol K and non-natural 2,3 dehydroisoxanthohumol exhibited the activity comparable to cisplatin. Results described in the article suggest that flavonoids containing chromane- and chromene-like moieties, especially chalcones, are potent antiproliferative agents. The developed new efficient, regioselective cyclisation reaction of the xanthohumol prenyl group to 1",2"-dihydroxantohumol K may be used in the synthesis of other compounds with the chromane moiety. PMID- 29597301 TI - Synthesis of Novel Amino Acid-Fipronil Conjugates and Study on Their Phloem Loading Mechanism. AB - To develop a new pesticide with phloem mobility, a series of new amino acid fipronil conjugates were designed and synthesized based on derivatization at the 3-position of the pyrazole ring of fipronil. Experiments using a Ricinus communis seedling system showed that all tested conjugates were phloem mobile except for the isoleucine-fipronil conjugate, and that the serine-fipronil conjugate (4g) exhibited the highest concentration in phloem sap (52.00 +/- 5.80 MUM). According to prediction with log Cf values and uptake experiments with Xenopus oocytes, the phloem loading process of conjugate 4g involved both passive diffusion and an active carrier system (RcANT15). In particular, compared with for a previously reported glycinergic-fipronil conjugate (GlyF), passive diffusion played a more important role for conjugate 4g in the enhancement of phloem mobility. This study suggests that associating a nutrient at a different position of an existing pesticide structure could still be effective in obtaining phloem-mobile derivatives, but the distinct physicochemical properties of resultant conjugates may lead to different phloem loading mechanisms. PMID- 29597302 TI - Effects of Basal Defoliation on Wine Aromas: A Meta-Analysis. AB - Basal defoliation, as one of the most common viticulture management practices to modify fruit zone microclimates, has been widely applied aiming at improving wine quality. Wine aroma contributes greatly to wine quality, yet the effects of basal defoliation on wine aromas show discrepancies according to previous studies. This study is a meta-analysis performed to dissect the factors related to the influence of basal defoliation on volatile compounds in wine. Timing of basal defoliation plays an important role in the concentration of varietal aromas in wine. Pre-veraison defoliation induces an increase in beta-damascenone and linalool as well as a reduction in 3-isobutyl-2-methoxypyrazine (IBMP). The effects of basal defoliation on certain volatile compounds relative to fermentation aromas in wine (1-hexanol, beta-phenylethanol, 2-phenylethyl acetate, decanoic acid, and ethyl octanoate) depend on grape maturity. There are also other factors, such as cultivar and climate conditions, that might be responsible for the effect of basal defoliation on wine aromas. The concentrations of isobutanol, isoamyl alcohol, hexanoic acid, and octanoic acid as well as ethyl isobutyrate, ethyl hexanoate, ethyl isovalerate, and ethyl decanoate in wine are not markedly affected by basal defoliation. Due to limited studies included in this meta-analysis, more trials are needed to confirm the current findings. PMID- 29597303 TI - Sensory Characteristics of Various Concentrations of Phenolic Compounds Potentially Associated with Smoked Aroma in Foods. AB - This research describes the sensory odor characteristics of 19 phenolic compounds (11 phenol derivatives, six guaiacol derivatives, and two syringol derivatives) that have been associated with smoked aroma in previous literature. Seven concentrations varying from 1 to 100,000 ppm of each chemical were examined. A highly trained descriptive panel used a recently published lexicon for smoky aroma and flavor and found that smoked aroma compounds have many different attributes that make up smokiness. Musty/dusty, musty/earthy, pungent, acid, smoky, woody, burnt, ashy, cedar, creosote or petroleum-like collectively imparted smoked aroma. Most of the phenolic compounds were described as having smoky characteristics at low concentrations, generally at 1 and 10 ppm, except 3,4-dimethylphenol at 5000 ppm. 2,6-Dimethylphenol was not associated with smoky characteristics. This research is the first to evaluate a set of phenolic compounds for their sensory characteristics using a professionally developed set of sensory attributes. PMID- 29597300 TI - Polymer-Mediated Delivery of siRNAs to Hepatocellular Carcinoma: Variables Affecting Specificity and Effectiveness. AB - Despite the advances in anticancer therapies, their effectiveness for many human tumors is still far from being optimal. Significant improvements in treatment efficacy can come from the enhancement of drug specificity. This goal may be achieved by combining the use of therapeutic molecules with tumor specific effects and delivery carriers with tumor targeting ability. In this regard, nucleic acid-based drug (NABD) and particularly small interfering RNAs (siRNAs), are attractive molecules due to the possibility to be engineered to target specific tumor genes. On the other hand, polymeric-based delivery systems are emerging as versatile carriers to generate tumor-targeted delivery systems. Here we will focus on the most recent findings in the selection of siRNA/polymeric targeted delivery systems for hepatocellular carcinoma (HCC), a human tumor for which currently available therapeutic approaches are poorly effective. In addition, we will discuss the most attracting and, in our opinion, promising siRNA-polymer combinations for HCC in relation to the biological features of HCC tissue. Attention will be also put on the mathematical description of the mechanisms ruling siRNA-carrier delivery, this being an important aspect to improve effectiveness reducing the experimental work.

PMID- 29597305 TI - Effects of Consuming a Low Dose of Alcohol with Mixers Containing Carbohydrate or Artificial Sweetener on Simulated Driving Performance. AB - The Australian National Drug and Alcohol Research Centre (NDARC) devised gender based drinking recommendations to ensure blood or equivalized breath alcohol concentrations (BrAC) remain <0.050%. However, these may be inappropriate for individuals consuming alcohol without carbohydrate (CHO), which results in higher BrACs. This study investigated the effects of ingesting alcohol with and without CHO on BrACs and simulated driving performance. Thirty-two participants (16 males; age: 23 +/- 6 years) completed two randomized single-blinded trials. Participants performed a baseline drive (Drive 1), then an experimental drive (Drive 2), following alcohol consumption (males: 20 g; females: 10 g). Alcoholic beverages contained either 25 g sucrose or aspartame (AS). Driving performance was assessed using lateral control (standard deviation of lane position [SDLP] and number of lane departures) and risk-taking (number of overtaking maneuvers and maximum overtaking speed). BrAC and subjective ratings (e.g., intoxication) were also assessed. BrAC was significantly lower as Drive 2 commenced with CHO compared to AS (0.022 +/- 0.008% vs. 0.030 +/- 0.011%). Two males provided BrACs >0.050% with AS. Neither beverage influenced changes to simulated driving performance. Ingesting alcohol in quantities advised by the NDARC results in no detectable simulated driving impairment. However, the likelihood of exceeding the legal drink-driving BrAC is increased when alcohol is consumed with artificially sweetened mixers. PMID- 29597307 TI - Factors Associated with High Live Release for Dogs at a Large, Open-Admission, Municipal Shelter. AB - Better understanding of factors contributing to live release (rehoming) may help shelters improve outcomes. In this cross-sectional, exploratory, non interventional study, data for all intakes (n = 21,409) for dogs eligible for rehoming from 1 January 2015 to 31 December 2016 are analyzed to identify such factors. Live release was >88%. A total of 1510 (7.1%) dogs interacted with the foster care system, 98.9% of whom had live release. Foster care increased the odds of live release by about five-fold for all dogs (odds ratio (OR) 5.30 (95% confidence interval (CI): 3.13; 8.97), p < 0.001) and by >20-fold for adult dogs (OR 22.2 (95% CI: 5.48; 90.2), p < 0.001) compared to first-time owner surrendered dogs. Dogs returned from foster care had a 70% reduction in health concerns, as judged by intake staff, compared with dogs sent to foster. In addition to saving 2882 lives, the rescue network utilized by this shelter was estimated as having reduced in-shelter care needs by 13,409 animal care-days over two years. Dogs returned from adoption also had increased odds of live release (OR 4.74 (95% CI: 3.02; 7.44), p < 0.0001). Nearly a third (29.6%) of dogs originally brought in by owners for euthanasia were determined to be potentially savable, and a fifth of the original group (21.1%) were ultimately placed. Less than 4% of dogs presented with behavioral concerns at intake. It remains to be determined whether other large, open intake shelters performing animal control can replicate these results. PMID- 29597306 TI - Biocompatibility of Gd-Loaded Chitosan-Hyaluronic Acid Nanogels as Contrast Agents for Magnetic Resonance Cancer Imaging. AB - Although the research on nanogels incorporating Gd chelates for theranostic applications has grown exponentially in recent years, knowledge about their biocompatibility is limited. We compared the biocompatibility of Gd-loaded hyaluronic acid-chitosan-based nanogels (GdCA?CS-TPP/HA) with two chitosan concentrations (2.5 and 1.5 mg.mL-1 respectively) using SVEC4-10 murine lymph node endothelial cells. The sulforhodamine B method and released lactate dehydrogenase (LDH) activity were used as cell viability tests. Reactive oxygen species (ROS), reduced glutathione (GSH) and malondialdehyde (MDA) were measured by spectrophotometric and fluorimetric methods. Nrf-2 protein expression was evaluated by Western blot analysis and genotoxicity by alkaline comet assay. After 24 h, the cells viability was not affected by all types and doses of nanogels. The increase of ROS induced a low decrease of GSH concentration and a time-dependent raise of MDA one was produced by citric GdDOTA?CS-TPP/HA with a chitosan concentration of 1.5 mg.mL-1, at the highest dose applied. None of the tested nanogels induced changes in Nrf-2 protein expression. A slight but significant genotoxic effect was caused only by citric GdDOTA?CS-TPP/HA where CS concentration was 1.5 mg.mL-1. Our results showed a better biocompatibility with lymph node endothelial cells for Gd-loaded hyaluronic acid-chitosan based nanogels with a concentration in chitosan of 2.5 mg.mL-1. PMID- 29597308 TI - 'Obesogenic' School Food Environments? An Urban Case Study in The Netherlands. AB - (1) Background: This study aimed to explore and define socio-economic (SES) differences in urban school food environments in The Netherlands. (2) Methods: Retail food outlets, ready-to-eat products, in-store food promotions and food advertisements in public space were determined within 400 m walking distance of all secondary schools in the 4th largest city of The Netherlands. Fisher's exact tests were conducted. (3) Results: In total, 115 retail outlets sold ready-to-eat food and drink products during school hours. Fast food outlets were more often in the vicinity of schools in lower SES (28.6%) than in higher SES areas (11.5%). In general, unhealthy options (e.g., fried snacks, sugar-sweetened beverages (SSB)) were more often for sale, in-store promoted or advertised in comparison with healthy options (e.g., fruit, vegetables, bottled water). Sport/energy drinks were more often for sale, and fried snacks/fries, hamburgers/kebab and SSB were more often promoted or advertised in lower SES areas than in higher SES-areas. (4) Conclusion: In general, unhealthy food options were more often presented than the healthy options, but only a few SES differences were observed. The results, however, imply that efforts in all school areas are needed to make the healthy option the default option during school time.

PMID- 29597310 TI - Optimization and Characterization of Preceramic Inks for Direct Ink Writing of Ceramic Matrix Composite Structures. AB - In a previous work, an ink based on a preceramic polymer, SiC fillers, and chopped carbon fibers was proposed for the production of Ceramic Matrix Composite (CMC) structures by Direct Ink Writing (DIW) and subsequent pyrolysis. Thanks to the shear stresses generated at the nozzle tip during extrusion, carbon fibers can be aligned along the printing direction. Fumed silica was added to the ink in order to enhance its rheological properties; however, the printed structures still showed some deformation in the Z direction. In this work, a second ink was successfully developed to limit deformation and at the same time avoid the addition of fumed silica, which limited the potential temperature of application of the composites. Instead, the positive role of the preceramic polymer on the ink rheology was exploited by increasing its concentration in the ink. Rheological characterization carried out on both inks confirmed that they possessed Bingham shear thinning behavior and fast viscosity recovery. Single filaments with different diameters (~310 um and ~460 um) were produced with the latter ink by DIW and subsequent pyrolysis. Tested under a four-point flexural test, the filaments showed a mean flexural strength above 30 MPa, graceful failure, and fiber pull-out. The results of this work suggest that CMC components can effectively be fabricated via DIW of a preceramic ink with embedded short fibers; the preceramic polymer is able to provide the desired rheology for the process and to develop a dense matrix capable of incorporating both fibers and ceramic particles, whereas the fibers addition contributes to an increase of the fracture toughness of the material and to the development of a graceful failure mode.

The commercial-sulfonated, tetrafluoroethylene-based fluoropolymer-copolymer (Nafion) membrane exhibits excellent proton conductivity under a fully humidified environment. However, it also has some disadvantages in practice, such as high fuel permeability, a complex synthesis process, and high cost. To overcome these disadvantages, a low-cost and novel membrane was developed. The sulfonated poly (ether ether ketone) (SPEEK) was selected as the base material of the proton exchange membrane. Sulfonated graphene (SG) was cross-linked with SPEEK through the elimination reaction of hydrogen bonds. It was found that the sulfonic acid groups and hydrophilic oxygen groups increased obviously in the resultant membrane. Compared with the pure SPEEK membrane, the SG-reinforced membrane exhibited better proton conductivity and methanol permeability prevention. The results indicate that the SG/SPEEK could be applied as a new proton exchange membrane in fuel cells.

AB - Functional materials of high porosity and hierarchical structure, based on renewable building blocks, are highly demanded for material applications. In this regard, substantial progress has been made by functionalizing micro- and nano sized cellulose followed by its reassembly via bottom-up approaches. However, bottom-up assembly processes are still limited in terms of upscaling and the utilization of these building blocks presupposes the disassembly of the plant feedstock inherit hierarchical cellulose scaffold. To maintain the three dimensional structure, delignification processes from pulp and paper production were recently adapted for the treatment of bulk wood. Yet, a detailed chemical analysis and the determination of macroscopic swelling/shrinkage parameters for the scaffolds, necessary for a systematic design of cellulose scaffold based materials, are still missing. Here, acidic bleaching and soda pulping were used for producing cellulose scaffolds, for functional materials under retention of their inherent hierarchical structure. Spatially resolved chemical investigations on thin sections by Raman microscopy provided detailed information on the induced alterations at the cell wall level, revealing significant differences in dependence of the chemistry of the pre-treatment. An adaption to bulk wood samples proved the applicability of these treatments at larger scales and volumetric alterations at different atmospheric conditions indicated the effect of the altered porosity of the scaffolds on their hygroscopic behaviour.

AB - A previous study has shown that tilapia fish skin gelatin hydrolysates inhibited photoaging in vivo, and that, Leu-Ser-Gly-Tyr-Gly-Pro (LSGYGP) identified in the hydrolysate had a high hydroxyl radical scavenging activity. In this study, activities of LSGYGP were further evaluated using ultraviolet B (UVB)-induced mouse embryonic fibroblasts (MEFs). UVB irradiation significantly increased the intercellular reactive oxygen species (ROS) production and matrix metalloproteinases (MMPs) activities and decreased the content of collagen in MEFs. LSGYGP reduced the intercellular ROS generation in UVB-induced MEFs. Meanwhile, the decrease of superoxide dismutase (SOD) activity and the increase of malondiaidehyde (MDA) content were inhibited by LSGYGP. LSGYGP reduced MMP-1 and MMP-9 activities in a dose-dependent manner. Molecular docking simulation indicated that LSGYGP inhibited MMPs activities by docking the active sites of MMP-1 and MMP-9. Furthermore, LSGYGP also affected the intercellular phosphorylation of UVB-induced the mitogen-activated protein kinase pathway. LSGYGP could protect collagen synthesis in MEFs under UVB irradiation by inhibiting oxidative stress and regulating MMPs activities.

AB - Swelling of mitochondria plays an important role in the pathogenesis of human diseases by stimulating mitochondria-mediated cell death through apoptosis, necrosis, and autophagy. Changes in the permeability of the inner mitochondrial membrane (IMM) of ions and other substances induce an increase in the colloid osmotic pressure, leading to matrix swelling. Modeling of mitochondrial swelling is important for simulation and prediction of in vivo events in the cell during oxidative and energy stress. In the present study, we developed a computational model that describes the mechanism of mitochondrial swelling based on osmosis, the rigidity of the IMM, and dynamics of ionic/neutral species. The model describes a new biophysical approach to swelling dynamics, where osmotic pressure created in the matrix is compensated for by the rigidity of the IMM, i.e., osmotic pressure induces membrane deformation, which compensates for the osmotic pressure effect. Thus, the effect is linear and reversible at small membrane deformations, allowing the membrane to restore its normal form. On the other hand, the membrane rigidity drops to zero at large deformations, and the swelling becomes irreversible. As a result, an increased number of dysfunctional mitochondria can activate mitophagy and initiate cell death. Numerical modeling analysis produced results that reasonably describe the experimental data reported earlier. PMID- 29597315 TI - Strategies on Nanodiagnostics and Nanotherapies of the Three Common Cancers. AB - The emergence of nanomedicine has enriched the knowledge and strategies of treating diseases, and especially some incurable diseases, such as cancers, acquired immune deficiency syndrome (AIDS), and neurodegenerative diseases. The application of nanoparticles in medicine is in the core of nanomedicine. Nanoparticles can be used in drug delivery for improving the uptake of poorly soluble drugs, targeted delivery to a specific site, and drug bioavailability. Early diagnosis of and targeted therapies for cancers can significantly improve patients' quality of life and extend patients' lives. The advantages of nanoparticles have given them a progressively important role in the nanodiagnosis and nanotherapy of common cancers. To provide a reference for the further application of nanoparticles, this review focuses on the recent development and application of nanoparticles in the early diagnosis and treatment of the three common cancers (lung cancer, liver cancer, and breast cancer) by using quantum dots, magnetic nanoparticles, and gold nanoparticles.

PMID- 29597317 TI - Contributions of Bioactive Molecules in Stem Cell-Based Periodontal Regeneration. AB - Periodontal disease is a widespread disease, which without proper treatment, may lead to tooth loss in adults. Because stem cells from the inflammatory microenvironment created by periodontal disease exhibit impaired regeneration potential even under favorable conditions, it is difficult to obtain satisfactory therapeutic outcomes using traditional treatments, which only focus on the control of inflammation. Therefore, a new stem cell-based therapy known as cell aggregates/cell sheets technology has emerged. This approach provides sufficient numbers of stem cells with high viability for treating the defective site and offers new hope in the field of periodontal regeneration. However, it is not sufficient for regenerating periodontal tissues by delivering cell aggregates/cell sheets to the impaired microenvironment in order to suppress the function of resident cells. In the present review, we summarize some promising bioactive molecules that act as cellular signals, which recreate a favorable microenvironment for tissue regeneration, recruit endogenous cells into the defective site and enhance the viability of exogenous cells. PMID- 29597319 TI - Beliefs about Vaccinations: Comparing a Sample from a Medical School to That from the General Population. AB - The current study compares health care professionals' beliefs about vaccination statements with the beliefs of a sample of individuals from the general population. Students and faculty within a medical school (n = 58) and a sample from the general population in the United States (n = 177) were surveyed regarding their beliefs about vaccinations. Participants evaluated statements about vaccinations (both supporting and opposing), and indicated whether they thought the general population would agree with them. Overall, it was found that subjects in both populations agreed with statements supporting vaccination over opposing statements, but the general population was more likely to categorize the supporting statements as beliefs rather than facts. Additionally, there was little consensus within each population as to which statements were considered facts versus beliefs. Both groups underestimated the number of people that would agree with them; however, the medical affiliates showed the effect significantly more. Implications for medical education and health communication are discussed. PMID- 29597318 TI - Can a Red Wood-Ant Nest Be Associated with Fault-Related CH4 Micro-Seepage? A Case Study from Continuous Short-Term In-Situ Sampling. AB - We measured methane (CH4) and stable carbon isotope of methane (delta13C-CH4) concentrations in ambient air and within a red wood-ant (RWA; Formica polyctena) nest in the Neuwied Basin (Germany) using high-resolution in-situ sampling to detect microbial, thermogenic, and abiotic fault-related micro-seepage of CH4. Methane degassing from RWA nests was not synchronized with earth tides, nor was it influenced by micro-earthquake degassing or concomitantly measured RWA activity. Two delta13C-CH4 signatures were identified in nest gas: -690/00 and 370/00. The lower peak was attributed to microbial decomposition of organic matter within the RWA nest, in line with previous observations that RWA nests are hot-spots of microbial CH4. The higher peak has not been reported in previous studies. We attribute this peak to fault-related CH4 emissions moving via fault networks into the RWA nest, which could originate either from thermogenic or abiotic CH4 formation. Sources of these micro-seepages could be Devonian schists, iron-bearing "Klerf Schichten", or overlapping micro-seepage of magmatic CH4 from the Eifel plume. Given the abundance of RWA nests on the landscape, their role as sources of microbial CH4 and biological indicators for abiotically-derived CH4 should be included in estimation of methane emissions that are contributing to climatic change. PMID- 29597320 TI - Water Quality in Surface Water: A Preliminary Assessment of Heavy Metal Contamination of the Mashavera River, Georgia. AB - Water quality contamination by heavy metal pollution has severe effects on public health. In the Mashavera River Basin, an important agricultural area for the national food system in Georgia (e.g., vegetable, dairy and wine production), water contamination has multiple influences on the regional and country-wide health. With new industrial activities in the region, sediment extraction, and discharge of untreated wastewater into the river, its tributaries and irrigation canals, a comprehensive study of water quality was greatly needed. This study examined sediment and water samples from 17 sampling sites in the Mashavera River Basin during the high and low precipitation seasons. The results were characterized utilizing the Geo-accumulation Index (Igeo), Enrichment Factor (EF), Pollution Load index (PLI), Contamination Factor (CF) and Metal Index (MI). According to the CFs, Cu > Cd > Zn > Pb > Fe > Mn > Ni > Cr > Hg is the descending order for the content of all observed heavy metals in sediments collected in both seasons. Fe and As were additionally examined in water samples. Overall, As, Cd and Pb, all highly toxic elements, were found in high concentrations in downstream sample sites. According to these results, comprehensive monitoring with narrow intervals between sampling dates, more sample sites along all waterways, and proximate observation of multiple trace metal elements are highly recommended. Moreover, as the part of the water quality governance system, an immediate and sustainable collective action by all stakeholders to control the pollution level is highly recommended, as this issue is linked to the security of the national food system and poses a local public health risk. PMID- 29597321 TI - Ectopic Overexpression of a Novel R2R3-MYB, NtMYB2 from Chinese Narcissus Represses Anthocyanin Biosynthesis in Tobacco. AB - R2R3 MYB transcription factors play key functions in the regulation of secondary metabolites. In the present study, a R2R3 MYB transcriptional factor NtMYB2 was identified from Chinese narcissus (Narcissus tazetta L. var. Chinensis Roem) and functionally characterized. NtMYB2 belongs to subgroup 4 of the R2R3 MYB transcription factor family that are related to repressor MYBs involved in the regulation of anthocyanin and flavonoids. Transient expression confirmed that NtMYB2 strongly reduced the red pigmentation induced by MYB- anthocyanin activators in agro-infiltrated tobacco leaves. Ectopic expression of NtMYB2 in tobacco significantly reduced the pigmentation and altered the floral phenotypes in transgenic tobacco flowers. Gene expression analysis suggested that NtMYB2 repressed the transcript levels of structural genes involved in anthocyanin biosynthesis pathway, especially the UFGT gene. NtMYB2 gene is expressed in all examined narcissus tissues; the levels of transcription in petals and corona is higher than other tissues and the transcription level at the bud stage was highest. These results show that NtMYB2 is involved in the regulation of anthocyanin biosynthesis pathway and may act as a repressor by down regulating the transcripts of key enzyme genes in Chinese narcissus. PMID- 29597323 TI - Sparse Unorganized Point Cloud Based Relative Pose Estimation for Uncooperative Space Target. AB - This paper proposes an autonomous algorithm to determine the relative pose between the chaser spacecraft and the uncooperative space target, which is essential in advanced space applications, e.g., on-orbit serving missions. The proposed method, named Congruent Tetrahedron Align (CTA) algorithm, uses the very sparse unorganized 3D point cloud acquired by a LIDAR sensor, and does not require any prior pose information. The core of the method is to determine the relative pose by looking for the congruent tetrahedron in scanning point cloud and model point cloud on the basis of its known model. The two-level index hash table is built for speeding up the search speed. In addition, the Iterative Closest Point (ICP) algorithm is used for pose tracking after CTA. In order to evaluate the method in arbitrary initial attitude, a simulated system is presented. Specifically, the performance of the proposed method to provide the initial pose needed for the tracking algorithm is demonstrated, as well as their robustness against noise. Finally, a field experiment is conducted and the results demonstrated the effectiveness of the proposed method. PMID- 29597322 TI - Aged (Black) versus Raw Garlic against Ischemia/Reperfusion-Induced Cardiac Complications. AB - Recent evidence from studies suggests that aged black garlic also has an effect on health. The major aim of the present study is to compare the effect of raw and aged black garlic on postischemic cardiac recovery. Male Sprague Dawley rats were randomly divided into three groups. Animals of the first group were fed with raw garlic, animals of the second group received aged black garlic, while the third group served as vehicle-treated controls. Upon conclusion of the treatment, isolated hearts were undertaken to ischemia/reperfusion. Heart function and infarct size were measured and the level of HO-1 and iNOS were studied. Superior postischemic cardiac function and reduced infarct size in both garlic treated groups compared to the drug-free control group, indicated cardioprotective effects. However, no significant differences between the garlic treated groups were observed. Western blot analysis revealed that raw garlic enhanced the level of HO-1 before ischemia, while in ischemic samples, we found elevated HO-1 expression in both garlic treated groups. The level of iNOS was the same before ischemia in all groups, however, a markedly reduced iNOS level in ischemic/reperfused hearts originating from control and raw garlic treated animals was observed. Samples from aged black garlic treated animals demonstrated that the level of iNOS was not significantly reduced after ischemia/reperfusion. Taken together these results indicate that not only raw but also aged black garlic possess a cardioprotective effect. PMID- 29597324 TI - Single-Kernel FT-NIR Spectroscopy for Detecting Supersweet Corn (Zea mays L. Saccharata Sturt) Seed Viability with Multivariate Data Analysis. AB - The viability and vigor of crop seeds are crucial indicators for evaluating seed quality, and high-quality seeds can increase agricultural yield. The conventional methods for assessing seed viability are time consuming, destructive, and labor intensive. Therefore, a rapid and nondestructive technique for testing seed viability has great potential benefits for agriculture. In this study, single kernel Fourier transform near-infrared (FT-NIR) spectroscopy with a wavelength range of 1000-2500 nm was used to distinguish viable and nonviable supersweet corn seeds. Various preprocessing algorithms coupled with partial least squares discriminant analysis (PLS-DA) were implemented to test the performance of classification models. The FT-NIR spectroscopy technique successfully differentiated viable seeds from seeds that were nonviable due to overheating or artificial aging. Correct classification rates for both heat-damaged kernels and artificially aged kernels reached 98.0%. The comprehensive model could also attain an accuracy of 98.7% when combining heat-damaged samples and artificially aged samples into one category. Overall, the FT-NIR technique with multivariate data analysis methods showed great potential capacity in rapidly and nondestructively detecting seed viability in supersweet corn. PMID- 29597325 TI - Diaphragm-Free Fiber-Optic Fabry-Perot Interferometric Gas Pressure Sensor for High Temperature Application. AB - A diaphragm-free fiber-optic Fabry-Perot (FP) interferometric gas pressure sensor is designed and experimentally verified in this paper. The FP cavity was fabricated by inserting a well-cut fiber Bragg grating (FBG) and hollow silica tube (HST) from both sides into a silica casing. The FP cavity length between the ends of the SMF and HST changes with the gas density. Using temperature decoupling method to improve the accuracy of the pressure sensor in high temperature environments. An experimental system for measuring the pressure under different temperatures was established to verify the performance of the sensor. The pressure sensitivity of the FP gas pressure sensor is 4.28 nm/MPa with a high linear pressure response over the range of 0.1-0.7 MPa, and the temperature sensitivity is 14.8 pm/ degrees C under the range of 20-800 degrees C. The sensor has less than 1.5% non-linearity at different temperatures by using temperature decoupling method. The simple fabrication and low-cost will help sensor to maintain the excellent features required by pressure measurement in high temperature applications. PMID- 29597326 TI - Experimental Study of the Oriented Immobilization of Antibodies on Photonic Sensing Structures by Using Protein A as an Intermediate Layer. AB - A proper antibody immobilization on a biosensor is a crucial step in order to obtain a high sensitivity to be able to detect low target analyte concentrations. In this paper, we present an experimental study of the immobilization process of antibodies as bioreceptors on a photonic ring resonator sensor. A protein A intermediate layer was created on the sensor surface in order to obtain an oriented immobilization of the antibodies, which enhances the interaction with the target antigens to be detected. The anti-bovine serum albumin (antiBSA) bovine serum albumin (BSA) pair was used as a model for our study. An opto fluidic setup was developed in order to flow the different reagents and, simultaneously, to monitor in real-time the spectral response of the photonic sensing structure. The antiBSA immobilization and the BSA detection, their repeatability, and specificity were studied in different conditions of the sensor surface. Finally, an experimental limit of detection for BSA recognition of only 1 ng/mL was obtained. PMID- 29597327 TI - A Simultaneous and Continuous Excitation Method for High-Speed Electrical Impedance Tomography with Reduced Transients and Noise Sensitivity. AB - This paper presents a concept for soft field tomographic scan of all the projections of electromagnetic waves emanating from an array of electrodes. Instead of the sequential excitation of all pairs of electrodes in the list of all projections, the new method present here consists of a single and continuous excitation. This excitation signal is the linear combination of the excitation signals in the projection set at different AC frequencies. The response to a given projection is discriminated by selecting the corresponding AC frequency component in the signal spectra of the digitally demodulated signals. The main advantage of this method is the suppression of transients after each projection, which is particularly problematic in electrical impedance tomography due to contact impedance phenomena and skin effect. The second benefit over the sequential scan method is the increased number of samples for each measurement for reduced noise sensitivity with digital demodulation. The third benefit is the increased temporal resolution in high-speed applications. The main drawback is the increased number of signal sources required (one per electrode). This paper focuses on electrical impedance tomography, based on earlier work by the authors. An experimental proof-of-concept using a simple 4-electrodes electrical impedance tomographic system is presented using simulations and laboratory data. The method presented here may be extended to other modalities (ultrasonic, microwave, optical, etc.).

AB - Closely related to the model plant Arabidopsis thaliana, the genus Boechera is known to contain both sexual and apomictic species or accessions. Boechera retrofracta is a diploid sexually reproducing species and is thought to be an ancestral parent species of apomictic species. Here we report the de novo assembly of the B. retrofracta genome using short Illumina and Roche reads from 1 paired-end and 3 mate pair libraries. The distribution of 23-mers from the paired end library has indicated a low level of heterozygosity and the presence of detectable duplications and triplications. The genome size was estimated to be equal 227 Mb. N50 of the assembled scaffolds was 2.3 Mb. Using a hybrid approach that combines homology-based and de novo methods 27,048 protein-coding genes were predicted. Also repeats, transfer RNA (tRNA) and ribosomal RNA (rRNA) genes were annotated. Finally, genes of B. retrofracta and 6 other Brassicaceae species were used for phylogenetic tree reconstruction. In addition, we explored the histidine exonuclease APOLLO locus, related to apomixis in Boechera, and proposed model of its evolution through the series of duplications. An assembled genome of B. retrofracta will help in the challenging assembly of the highly heterozygous genomes of hybrid apomictic species. PMID- 29597329 TI - The Human Tyrosyl-DNA Phosphodiesterase 1 (hTdp1) Inhibitor NSC120686 as an Exploratory Tool to Investigate Plant Tdp1 Genes. AB - The hTdp1 (human tyrosyl-DNA phosphodiesterase 1) inhibitor NSC120686 has been used, along with topoisomerase inhibitors, as a pharmacophoric model to restrain the Tdp1 activity as part of a synergistic treatment for cancer. While this compound has an end-point application in medical research, in plants, its application has not been considered so far. The originality of our study consists in the use of hTdp1 inhibitor in Medicago truncatula cells, which, unlike human cells, contain two Tdp1 genes. Hence, the purpose of this study was to test the hTdp1 inhibitor NSC120686 as an exploratory tool to investigate the plant Tdp1 genes, since their characterization is still in incipient phases. To do so, M. truncatula calli were exposed to increasing (75, 150, 300 MUM) concentrations of NSC120686. The levels of cell mortality and DNA damage, measured via diffusion assay and comet assay, respectively, were significantly increased when the highest doses were used, indicative of a cytotoxic and genotoxic threshold. In addition, the NSC120686-treated calli and untreated MtTdp1alpha-depleted calli shared a similar response in terms of programmed cell death (PCD)/necrosis and DNA damage. Interestingly, the expression profiles of MtTdp1alpha and MtTdp1beta genes were differently affected by the NSC120686 treatment, as MtTdp1alpha was upregulated while MtTdp1beta was downregulated. The NSC120686 treatment affected not only the MtTdp1 genes but also other genes with roles in alternative DNA repair pathways. Since the expression patterns of these genes were different than what was observed in the MtTdp1alpha-depleted plants, it could be hypothesized that the NSC120686 treatment exerts a different influence compared to that resulting from the lack of the MtTdp1alpha gene function. PMID- 29597330 TI - Investigation of Absorption Routes of Meloxicam and Its Salt Form from Intranasal Delivery Systems. AB - The aim of this article was to study the trans-epithelial absorption to reach the blood and to target the brain by axonal transport using nasal formulations with nanonized meloxicam (nano MEL spray) and its salt form known as meloxicam potassium monohydrate (MELP spray). The physicochemical properties and the mucoadhesivity of nasal formulations were controlled. In vitro and in vivo studies were carried out. These forms were first investigated in "nose-to-brain" relation. It was found that the in vitro study and in vivo study did not show any significant correlation. In vitro experiments demonstrated faster dissolution rate and higher diffusion of MELP from the spray compared with the nano MEL spray. The administration of the nano MEL spray resulted in faster absorption and constant plasma concentration of the drug after five minutes of administration as compared to MELP. The axonal transport of the drug was justified. MEL appeared in the brain tissues after the first five minutes of administration in the case of both spray forms, but its amount was too small in comparison with the total plasma concentration. The application of the nano MEL spray resulted in the same AUC in the brain as the intravenous injection. The "nose-to-blood" results predicted the nasal applicability of MEL and MELP in pain management. The "nose to-brain" pathway requires further study.

AB - Although some researchers have proposed the Field Programmable Gate Array (FPGA) architectures of Feature From Accelerated Segment Test (FAST) and Binary Robust Independent Elementary Features (BRIEF) algorithm, there is no consideration of image data storage in these traditional architectures that will result in no image data that can be reused by the follow-up algorithms. This paper proposes a new FPGA architecture that considers the reuse of sub-image data. In the proposed architecture, a remainder-based method is firstly designed for reading the sub image, a FAST detector and a BRIEF descriptor are combined for corner detection and matching. Six pairs of satellite images with different textures, which are located in the Mentougou district, Beijing, China, are used to evaluate the performance of the proposed architecture. The Modelsim simulation results found that: (i) the proposed architecture is effective for sub-image reading from DDR3 at a minimum cost; (ii) the FPGA implementation is corrected and efficient for corner detection and matching, such as the average value of matching rate of natural areas and artificial areas are approximately 67% and 83%, respectively, which are close to PC's and the processing speed by FPGA is approximately 31 and 2.5 times faster than those by PC processing and by GPU processing, respectively.

AB - Diverse ligands of the muscle nicotinic acetylcholine receptor (nAChR) are used as muscle relaxants during surgery. Although a plethora of such molecules exists in the market, there is still a need for new drugs with rapid on/off-set, increased selectivity, and so forth. We found that pyrroloiminoquinone alkaloid Makaluvamine G (MG) inhibits several subtypes of nicotinic receptors and ionotropic gamma-aminobutiric acid receptors, showing a higher affinity and moderate selectivity toward muscle nAChR. The action of MG on the latter was studied by a combination of electrophysiology, radioligand assay, fluorescent microscopy, and computer modeling. MG reveals a combination of competitive and un competitive inhibition and caused an increase in the apparent desensitization rate of the murine muscle nAChR. Modeling ion channel kinetics provided evidence for MG binding in both orthosteric and allosteric sites. We also demonstrated that thealpha1 (G153S) mutant of the receptor, associated with the myasthenic syndrome, is more prone to inhibition by MG. Thus, MG appears to be a perspective hit molecule for the design of allosteric drugs targeting muscle nAChR, especially for treating slow-channel congenital myasthenic syndromes. PMID- 29597333 TI - From the Child's Word to Clinical Intervention: Novel, New, and Innovative Approaches to Symptoms in Pediatric Palliative Care. AB - Despite vast improvements in disease-based treatments, many children live with life-threatening disorders that cause distressing symptoms. These symptoms can be difficult to comprehensively assess and manage. Yet, frequent and accurate symptom reporting and expert treatment is critical to preserving a patient's physical, psychological, emotional, social, and existential heath. We describe emerging methods of symptom and health-related quality-of-life (HRQOL) assessment through patient-reported outcomes (PROs) tools now used in clinical practice and novel research studies. Computer-based and mobile apps can facilitate assessment of symptoms and HRQOL. These technologies can be used alone or combined with therapeutic strategies to improve symptoms and coping skills. We review technological advancements, including mobile apps and toys, that allow improved symptom reporting and management. Lastly, we explore the value of a pediatric palliative care interdisciplinary team and their role in assessing and managing distressing symptoms and minimizing suffering in both the child and family. These methods and tools highlight the way that novel, new, and innovative approaches to symptom assessment and management are changing the way that pediatrics and pediatric palliative care will be practiced in the future. PMID- 29597334 TI - Microglia after Seizures and in Epilepsy. AB - Microglia are the resident immune cells in the brain that constitute the brain's innate immune system. Recent studies have revealed various functions of microglia in the development and maintenance of the central nervous system (CNS) in both health and disease. However, the role of microglia in epilepsy remains largely undiscovered, partly because of the complex phenotypes of activated microglia. Activated microglia likely exert different effects on brain function depending on the phase of epileptogenesis. In this review, we mainly focus on the animal models of temporal lobe epilepsy (TLE) and discuss the proepileptic and antiepileptic roles of activated microglia in the epileptic brain. Specifically, we focus on the roles of microglia in the production of inflammatory cytokines, regulation of neurogenesis, and surveillance of the surrounding environment in epilepsy.

AB - The pathogenesis of enteric zoster, a rare debilitating complication of reactivation of latent varicella-zoster virus (VZV) in the enteric nervous system (ENS), is largely unknown. Infection of monkeys with the closely related Varicellovirus simian varicella virus (SVV) mimics VZV disease in humans. In this study, we determined the applicability of the SVV nonhuman primate model to study Varicellovirus infection of the ENS. We confirmed VZV infection of the gut in latently infected adults and demonstrated that SVV DNA was similarly present in gut of monkeys latently infected with SVV using quantitative real-time PCR. In situ analyses showed that enteric neurons expressed SVV open reading frame (ORF) 63 RNA, but not viral nucleocapsid proteins, suggestive of latent ENS infection. During primary infection, SVV-infected T-cells were detected in gut-draining mesenteric lymph nodes and located in close vicinity to enteric nerves in the gut. Furthermore, flow cytometric analysis of blood from acutely SVV-infected monkeys demonstrated that virus-infected T-cells expressed the gut-homing receptor alpha4beta7 integrin. Collectively, the data demonstrate that SVV infects ENS neurons during primary infection and supports the role of T-cells in virus dissemination to the gut. Because SVV reactivation can be experimentally induced, the SVV nonhuman primate model holds great potential to study the pathogenesis of enteric zoster. PMID- 29597337 TI - Behavioral Intervention in Adolescents Improves Bone Mass, Yet Lactose Maldigestion Is a Barrier. AB - Calcium intake during adolescence is important for attainment of peak bone mass. Lactose maldigestion is an autosomal recessive trait, leading to lower calcium intake. The Adequate Calcium Today study aimed to determine if a school-based targeted behavioral intervention over one year could improve calcium intake and bone mass in early adolescent girls. The school-randomized intervention was conducted at middle schools in six states over one school year. A total of 473 girls aged 10-13 years were recruited for outcome assessments. Bone mineral content (BMC) was determined by dual energy X-ray absorptiometry. Dietary calcium intake was assessed with a semi-quantitative food frequency questionnaire. Baseline calcium intake and BMC were not significantly different between groups. After the intervention period, there were no differences in changes in calcium intake and BMC at any site between groups. An unanticipated outcome was a greater increase in spinal BMC among lactose digesters than lactose maldigesters in the intervention schools only (12 months) (6.9 +/- 0.3 g vs. 6.0 +/- 0.4 g, p = 0.03) and considering the entire study period (18 months) (9.9 +/- 0.4 vs. 8.7 +/- 0.5 g, p < 0.01). Overall, no significant differences between the intervention and control schools were observed. However, lactose digesters who received the intervention program increased bone mass to a greater extent than lactose maldigesters. PMID- 29597336 TI - Comparative Evaluation of the Antioxidant and Anti-Alzheimer's Disease Potential of Coumestrol and Puerarol Isolated from Pueraria lobata Using Molecular Modeling Studies. AB - The current study assesses the antioxidant effects of two similar isoflavonoids isolated from Pueraria lobata, coumestrol and puerarol, along with the cholinergic and amyloid-cascade pathways to mitigate Alzheimer's disease (AD). Antioxidant activity was evaluated via 1,1-diphenyl-2-picryhydrazyl (DPPH) and peroxynitrite (ONOO-) scavenging ability further screened via ONOO--mediated nitrotyrosine. Similarly, acetyl- and butyrylcholinesterase (AChE/BChE) and beta site amyloid precursor protein cleaving enzyme 1 (BACE1) inhibitory activities were assessed together with docking and kinetic studies. Considering DPPH and ONOO- scavenging activity, coumestrol (EC50 values of 53.98 and 1.17 uM) was found to be more potent than puerarol (EC50 values of 82.55 and 6.99 uM) followed by dose dependent inhibition of ONOO--mediated nitrotyrosine. Coumestrol showed pronounced AChE and BChE activity with IC50 values of 42.33 and 24.64 uM, respectively, acting as a dual cholinesterase (ChE) inhibitor. Despite having weak ChE inhibitory activity, puerarol showed potent BACE1 inhibition (28.17 uM). Kinetic studies of coumestrol showed AChE and BChE inhibition in a competitive and mixed fashion, whereas puerarol showed mixed inhibition for BACE1. In addition, docking simulations demonstrated high affinity and tight binding capacity towards the active site of the enzymes. In summary, we undertook a comparative study of two similar isoflavonoids differing only by a single aliphatic side chain and demonstrated that antioxidant agents coumestrol and puerarol are promising, potentially complementary therapeutics for AD. PMID- 29597338 TI - Dose-Response Modelling of Paralytic Shellfish Poisoning (PSP) in Humans. AB - Paralytic shellfish poisoning (PSP) is caused by a group of marine toxins with saxitoxin (STX) as the reference compound. Symptoms in humans after consumption of contaminated shellfish vary from slight neurological and gastrointestinal effects to fatal respiratory paralysis. A systematic review was conducted to identify reported cases of human poisoning associated with the ingestion of shellfish contaminated with paralytic shellfish toxins (PSTs). Raw data were collected from 143 exposed individuals (113 with symptoms, 30 without symptoms) from 13 studies. Exposure estimates were based on mouse bioassays except in one study. A significant relationship between exposure to PSTs and severity of symptoms was established by ordinal modelling. The critical minimal dose with a probability higher than 10% of showing symptoms is 0.37 ug STX eq./kg b.w. This means that 10% of the individuals exposed to this dose would have symptoms (without considering the severity of the symptoms). This dose is four-fold lower than the lowest-observed-adverse-effect-level (LOAEL) established by the European Food Safety Authority (EFSA, 2009) in the region of 1.5 MUg STX eq./kg b.w. This work provides critical doses that could be used as point of departure to update the acute reference dose for STX. This is the first time a dose-symptoms model could be built for marine toxins using epidemiological data. PMID- 29597339 TI - omega-Methylsulfanylalkyl Glucosinolates: A General Synthetic Pathway. AB - A general pathway was devised to synthesize omega-methylsulfanylalkyl glucosinolates, which represent an important class of structurally homogeneous plant secondary metabolites. The required thiofunctionalized hydroximoyl chlorides were obtained from the corresponding alpha,omega-nitroalkyl methylsulfide precursors, involving as the key-step, a nitronate chlorination strategy. A coupling reaction with 1-thio-beta-d-glucopyranose, followed by O sulfation of the intermediate thiohydroximate and final deprotection of the sugar moiety afforded the target compounds. PMID- 29597340 TI - Alpha Particle Detection Using Alpha-Induced Air Radioluminescence: A Review and Future Prospects for Preliminary Radiological Characterisation for Nuclear Facilities Decommissioning. AB - The United Kingdom (UK) has a significant legacy of nuclear installations to be decommissioned over the next 100 years and a thorough characterisation is required prior to the development of a detailed decommissioning plan. Alpha radiation detection is notoriously time consuming and difficult to carry out due to the short range of alpha particles in air. Long-range detection of alpha particles is therefore highly desirable and this has been attempted through the detection of secondary effects from alpha radiation, most notably the air radioluminescence caused by ionisation. This paper evaluates alpha induced air radioluminescence detectors developed to date and looks at their potential to develop a stand-off, alpha radiation detector which can be used in the nuclear decommissioning field in daylight conditions to detect alpha contaminated materials. PMID- 29597341 TI - Parents' Experience and Views of Vaccinating Their Child against Influenza at Primary School and at the General Practice. AB - The purpose of this study was to gain an in-depth understanding of parents' experience and views of vaccinating their four to six-year-old child against influenza at school and at the general practice (GP). A cross-sectional qualitative study was conducted between March-June 2016 with parents of children in Reception and Year 1 in four randomly selected schools in Bury, Leicestershire, and Surrey, England. Twenty-five outreach forms were completed and returned, and seven interviews were conducted. Interview transcripts were coded by theme in NVivo (version 11, QSR International Pty Ltd., Melbourne, Australia). The primary reason parents gave for vaccinating their child was to prevent their child from contracting influenza. Parents' perceived benefits of vaccinating in schools were to avoid the inconvenience of having to take their child to the GP, and that their child would behave better at school. Parents viewed that accompanying their child for the vaccination at school would undermine the convenience and peer-pressure advantages of the school as a venue. No parents expressed concern about their child being too young to be vaccinated in school. This research suggests that the school is a desirable venue for childhood influenza vaccination, both from the parents' view and given that influenza vaccination coverage is higher when delivered through schools than GPs. PMID- 29597342 TI - Study on Betalains in Celosia cristata Linn. Callus Culture and Identification of New Malonylated Amaranthins. AB - Betacyanins and betaxanthins were characterized and determined in an intensely pigmented red-colored callus culture of Celosia cristata L. (Amaranthaceae). A new malonyl derivative, 6'- O-malonyl-amaranthin (celoscristatin) was isolated and identified by spectroscopic and mass spectrometric techniques. Its stereoisomer, 4'- O-malonyl-amaranthin (celoscristatin acyl-migrated), as well as its 15 R diastereomer were also detected in the callus as a result of the malonyl group migration in celoscristatin/isoceloscristatin, respectively. Amaranthin occurs in the callus as the major betacyanin, followed by celoscristatin, betanin, phyllocactin, and other minor betacyanins. The effect of different carbon sources on the growth rates of the Celosia callus as well as on betalains profiles in the callus cultures was studied. High dopamine content in the callus culture was determined and compared with the content in C. cristata inflorescences. The dopamine-based betalain (miraxanthin V) was detected as the main betaxanthin in the callus, however, at a concentration level much lower than that of the identified betacyanins. The studied callus culture of C. cristata can accumulate betalains in amounts which approach the quantities produced by most known high-yielding plant species. PMID- 29597344 TI - Rhabdopeptides from Xenorhabdus budapestensis SN84 and Their Nematicidal Activities against Meloidogyne incognita. AB - For decades, plant parasitic nematodes have caused serious damage to crop production. Most nematicides are banned because of their negative impacts on the environment and public health. The repeated application of the few commercially available nematicides has caused more incidences of nematicide resistance. To seek novel nematicides, seven linear peptides named rhabdopeptides I-O, 1-7, were isolated from culture broth of Xenorhabdus budapestensis SN84. The structures of the peptides were elucidated on the basis of extensive mass spectrometry (MS), and nuclear magnetic resonance analyses. 3, 4, and 7 were novel compounds. 1, 2, 5, and 6 were isolated and purified for the first time, despite being previously elucidated from an extract mixture based on labeling and MS experiments. All seven compounds were tested for their nematicidal activities against the second stage juveniles (J2) of Meloidogyne incognita using 24-microwell plates. Rhabdopeptide J, 2, demonstrated strong inhibitory activity with an LC50 value of 27.8 MUg/mL. Rhabdopeptide K, 3, and M, 5, showed moderate inhibitory activity with LC50 values of 46.3 and 42.4 MUg/mL, respectively. PMID- 29597343 TI - Dopamine D1-Like Receptor Agonist and D2-Like Receptor Antagonist (-) Stepholidine Reduces Reinstatement of Drug-Seeking Behavior for 3,4 Methylenedioxypyrovalerone (MDPV) in Rats. AB - Psychostimulant reinforcement is mediated by stimulation of both dopamine (DA) D1 like and D2-like receptors, suggesting that pharmacotherapy agents with a dual DA receptor mechanism may be useful for managing psychostimulant abuse. (-) Stepholidine (L-SPD) is a Chinese herbal extract that functions as a D1-like receptor agonist and D2-like receptor antagonist. L-SPD has been shown to attenuate the reinforcing effects of heroin; however, its effects on the synthetic cathinone 3,4-methylenedioxypyrovalerone (MDPV) have not been examined. The current study determined the effects of L-SPD on reinstatement of MDPV seeking behavior in the drug intravenous self-administration (IVSA) and conditioned place preference (CPP) paradigms. To determine whether the effects of L-SPD were specific to psychostimulant reinforcement, we also examined its effects on sucrose-seeking behavior. Using a locomotor activity assay, we tested the locomotor effects of L-SPD, as well as its effects on MDPV-induced hyperactivity. The results of a battery of in vitro binding and functional assays confirmed that L-SPD functioned as a D1-like receptor agonist and D2-like receptor antagonist. In behavioral experiments, L-SPD dose-dependently attenuated cue plus MDPV-primed reinstatement of MDPV-seeking behavior in the IVSA model. The highest dose of L-SPD also attenuated MDPV-primed reinstatement of MDPV CPP, as well as cue-induced reinstatement of sucrose-seeking. L-SPD had no significant locomotor effects, and did not modulate the robust hyperactivity induced by MDPV. The current findings show for the first time a robust reinstatement effect with MDPV, which can be reduced by L-SPD. These results establish a role for DA receptors in drug-seeking behavior for MDPV. PMID- 29597346 TI - Porosity Prediction through Hydrogen Bonding in Covalent Organic Frameworks. AB - Easy and bulk-scale syntheses of two-dimensional (2D) covalent organic frameworks (COFs) represent an enduring challenge in material science. Concomitantly, the most critical aspect is to precisely control the porosity and crystallinity of these robust structures. Disparate complementary approaches such as solvothermal synthesis have emerged recently and are fueled in part by the usage of different modulators and acids that have enriched the COF library. Yet, the fundamental understanding of the integral processes of 2D COF assembly, including their growth from nucleating sites and the origin of periodicity, is an intriguing chemical question that needs to be answered. To address these cardinal questions, a green and easy-to-perform approach of COF formation has been delineated involving acid-diamine salt precursors. The role of hydrogen bonding [ dav(Namine H...Oacid); dav signifies the average Namine-H...Oacid distances, i.e., the average distance from the H atom of the amine to the O atom of the acid] present in the acid-diamine salts in improving the COFs' crystallinity and porosity has further been decoded by thorough crystallographic analyses of the salt molecules. What is particularly noteworthy is that we have established the hydrogen-bonding distances dav(Namine-H...Oacid) in the acid-diamine salts that are pivotal in maintaining the reversibility of the reaction, which mainly facilitates highly crystalline and porous COF formation. Moreover, this reactant-structure to the product-quality relationship has further been utilized for the synthesis of highly crystalline and porous COFs that are unattainable by other synthetic means. PMID- 29597345 TI - DNA Methylome Marks of Exposure to Particulate Matter at Three Time Points in Early Life. AB - Maternal exposure to airborne particulate matter (PM) has been associated with restricted fetal growth and reduced birthweight. Here, we performed methylome wide analyses of cord and children's blood DNA in relation to residential exposure to PM smaller than 10 MUm (PM10). This study included participants of the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC, cord blood, n = 780; blood at age 7, n = 757 and age 15-17, n = 850) and the EXPOsOMICS birth cohort consortium including cord blood from ENVIR ONAGE ( n = 197), INMA ( n = 84), Piccolipiu ( n = 99) and Rhea ( n = 75). We could not identify significant CpG sites, by meta-analyzing associations between maternal PM10 exposure during pregnancy and DNA methylation in cord blood, nor by studying DNA methylation and concordant annual exposure at 7 and 15-17 years. The CpG cg21785536 was inversely associated with PM10 exposure using a longitudinal model integrating the three studied age groups (-1.2% per 10 MUg/m3; raw p-value = 3.82 * 10-8). Pathway analyses on the corresponding genes of the 100 strongest associated CpG sites of the longitudinal model revealed enriched pathways relating to the GABAergic synapse, p53 signaling and NOTCH1. We provided evidence that residential PM10 exposure in early life affects methylation of the CpG cg21785536 located on the EGF Domain Specific O-Linked N-Acetylglucosamine Transferase gene. PMID- 29597347 TI - Enzymatic Preparation of a Homologous Series of Long-Chain 6- O-Acylglucose Esters and Their Evaluation as Emulsifiers. AB - Sugar fatty acid esters are nonionic surfactants that are widely exploited in the food and cosmetics industries, as well as in the oral care and medical supply fields. Accordingly, new methods for their selective synthesis and the "tuning" of their emulsifying properties are of considerable interest. Herein we report simple and irreversible enzymatic esterifications of d-glucose with seven fatty acid vinyl esters. The foaming and emulsifying effects of the resulting 6- O acylglucose esters were then evaluated. In accord with expectations, when the length of the alkyl side chain associated with the 6- O-acylglucose esters increases, then their hydrophilic-lipophilic balance (HLB) values decrease, while the stabilities of the derived emulsions improve. In order to maintain good foaming properties, alkyl side chains of at least 9 to 11 carbons in length are required. In the first such assays on 6- O-acylglucose esters, most of those described herein are shown to be nontoxic to the HepG2, MCF-7, LNacp, SW549, and LO-2 cell lines. PMID- 29597348 TI - Infrared Photodissociation Spectra of [Sn(CO2) n]- Cluster Ions. AB - We present infrared spectra and density functional theory calculations of mass selected [Sn(CO2) n]- cluster anions ( n = 2-6). The spectra and structures of these clusters exhibit less structural diversity than those of analogous clusters with first-row transition metals, but are more complex than those for the heavy coinage metals or for the related [Bi(CO2) n]- clusters. The most favorable core ion structure for all cluster sizes can be characterized as a Sn-oxalate complex, Sn[C2O4]-. Higher energy isomers based on a bidentate eta2-(C,O) CO2 ligand tightly bound to the metal atom in SnCO2- complexes are also observed, even for the largest cluster sizes studied here. For n = 2, another high energy isomer is found, featuring a CO2 ligand weakly bound to the metal atom in a SnCO2- ion. PMID- 29597349 TI - Numerical Study of Surfactant Dynamics during Emulsification in a T-Junction Microchannel. AB - Microchannel emulsification requires large amounts of surfactant to prevent coalescence and improve emulsions lifetime. However, most numerical studies have considered surfactant-free mixtures as models for droplet formation in microchannels, without taking into account the distribution of surfactant on the droplet surface. In this paper, we investigate the effects of nonuniform surfactant coverage on the microfluidic flow pattern using an extended lattice Boltzmann model. This numerical study, supported by micro-particle image velocimetry experiments, reveals the likelihood of uneven distribution of surfactant during the droplet formation and the appearance of a stagnant cap. The Marangoni effect affects the droplet breakup by increasing the shear rate. According to our results, surfactant-free and surfactant-rich droplet formation processes are qualitatively different, such that both the capillary number and the Damkohler number should be considered when modeling the droplet generation in microfluidic devices. The limitations of traditional volume and pressure estimation methods for determining the dynamic interfacial tension are also discussed on the basis of the simulation results.

AB - A siloxane surface-anchored quaternary ammonium salt (AQAS: BIOSAFE HM4100 in this study) has been chemisorbed onto a quartz substrate. The aim of this study is to elucidate, using atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS), the structure of the chemisorbed AQAS layers. The AQAS biocide includes a C18 alkyl chain previously invoked in lysis potency. The AQAS coverage appears in zones on the surface, which include a first layer (2.6 +/- 0.1 nm) and multilayering that were explored using AFM. The XPS data exhibited two N 1s signals at about 402 and 399 eV, with only the former exhibiting angular dependence. This signal at 402 eV was assigned to the first anchored layer with perpendicular orientation determined by the AQAS anchoring to the surface. In preliminary AFM studies of bacteria on these AQAS surfaces, perturbations on the Staphylococcus aureus cells and the degradation of Escherichia coli cells suggest lysis potency. PMID- 29597351 TI - Fluorescent Supracolloidal Chains of Patchy Micelles of Diblock Copolymers Functionalized with Fluorophores. AB - By selective attachment of fluorescent dyes to the core-forming block, we produced patchy micelles of diblock copolymers with fluorophores localized in the micellar cores. From these patchy micelles functionalized with dyes, fluorescent supracolloidal chains in a few micrometers were polymerized by combining the patches in neighboring micelles, indicating that selective modification of the core-forming block delivered the functionality into the supracolloidal chain without altering the polymerization of patchy micelles. Thus, with the same polymerization condition, we were able to produce red-, green-, and blue-emitting supracolloidal chains by varying the fluorescent dyes attached to the core forming block. In addition, we directly visualized individual supracolloidal chains by fluorescence confocal microscopy as well as by transmission electron microscopy. PMID- 29597352 TI - Clostridium difficile toxins A and B decrease intestinal SLC26A3 protein expression. AB - Clostridium difficile infection (CDI) is the primary cause of nosocomial diarrhea in the United States. Although C. difficile toxins A and B are the primary mediators of CDI, the overall pathophysiology underlying C. difficile-associated diarrhea remains poorly understood. Studies have shown that a decrease in both NHE3 (Na+/H+ exchanger) and DRA (downregulated in adenoma, Cl-/[Formula: see text] exchanger), resulting in decreased electrolyte absorption, is implicated in infectious and inflammatory diarrhea. Furthermore, studies have shown that NHE3 is depleted at the apical surface of intestinal epithelial cells and downregulated in patients with CDI, but the role of DRA in CDI remains unknown. In the current studies, we examined the effects of C. difficile toxins TcdA and TcdB on DRA protein and mRNA levels in intestinal epithelial cells (IECs). Our data demonstrated that DRA protein levels were significantly reduced in response to TcdA and TcdB in IECs in culture. This effect was also specific to DRA, as NHE3 and PAT-1 (putative anion transporter 1) protein levels were unaffected by TcdA and TcdB. Additionally, purified TcdA and TcdA + TcdB, but not TcdB, resulted in a decrease in colonic DRA protein levels in a toxigenic mouse model of CDI. Finally, patients with recurrent CDI also exhibited significantly reduced expression of colonic DRA protein. Together, these findings indicate that C. difficile toxins markedly downregulate intestinal expression of DRA which may contribute to the diarrheal phenotype of CDI. NEW & NOTEWORTHY Our studies demonstrate, for the first time, that C. difficile toxins reduce DRA protein, but not mRNA, levels in intestinal epithelial cells. These findings suggest that a downregulation of DRA may be a critical factor in C. difficile infection associated diarrhea. PMID- 29597353 TI - Extracellular adenosine: a critical signal in liver fibrosis. AB - Extracellular adenosine nucleoside is a potent, endogenous mediator that signals through specific G protein-coupled receptors, and exerts pleiotropic effects on liver physiology, in health and disease. Particularly, adenosinergic or adenosine mediated signaling pathways impact the progression of hepatic fibrosis, a common feature of chronic liver diseases, through regulation of matrix deposition by liver myofibroblasts. This review examines the current lines of evidence on adenosinergic regulation of liver fibrosis and myofibroblasts, identifies unanswered research questions, and proposes important future areas of investigation. PMID- 29597354 TI - Protein fermentation in the gut; implications for intestinal dysfunction in humans, pigs, and poultry. AB - The amount of dietary protein is associated with intestinal disease in different vertebrate species. In humans, this is exemplified by the association between high-protein intake and fermentation metabolite concentrations in patients with inflammatory bowel disease. In production animals, dietary protein intake is associated with postweaning diarrhea in piglets and with the occurrence of wet litter in poultry. The underlying mechanisms by which dietary protein contributes to intestinal problems remain largely unknown. Fermentation of undigested protein in the hindgut results in formation of fermentation products including short chain fatty acids, branched-chain fatty acids, ammonia, phenolic and indolic compounds, biogenic amines, hydrogen sulfide, and nitric oxide. Here, we review the mechanisms by which these metabolites may cause intestinal disease. Studies addressing how different metabolites induce epithelial damage rely mainly on cell culture studies and occasionally on mice or rat models. Often, contrasting results were reported. The direct relevance of such studies for human, pig, and poultry gut health is therefore questionable and does not suffice for the development of interventions to improve gut health. We discuss a roadmap to improve our understanding of gut metabolites and microbial species associated with intestinal health in humans and production animals and to determine whether these metabolite/bacterial networks cause epithelial damage. The outcomes of these studies will dictate proof-of-principle studies to eliminate specific metabolites and or bacterial strains and will provide the basis for interventions aiming to improve gut health.

AB - The last few decades have seen a major increase in the number of neurotransmitters and neuropeptides recognized as playing a role in brain stem neurocircuits, including those involved in homeostatic functions such as stress responsiveness, gastrointestinal motility, feeding, and/or arousal/wakefulness. This minireview will focus on the known physiological role of three of these novel neuropeptides, i.e., apelin, nesfatin-1, and neuropeptide-S, with a special emphasis on their hypothetical roles in vagal signaling related to gastrointestinal motor functions. PMID- 29597831 TI - Developmental differences in focal adhesion kinase expression modulate pulmonary endothelial barrier function in response to inflammation. AB - Compromised pulmonary endothelial cell (PEC) barrier function characterizes acute respiratory distress syndrome (ARDS), a cause of substantial morbidity and mortality. Survival from ARDS is greater in children compared with adults. Whether developmental differences intrinsic to PEC barrier function contribute to this survival advantage remains unknown. To test the hypothesis that PEC barrier function is more well-preserved in neonatal lungs compared with adult lungs in response to inflammation, we induced lung injury in neonatal and adult mice with systemic lipopolysaccharide (LPS). We assessed PEC barrier function in vivo and in vitro, evaluated changes in the expression of focal adhesion kinase 1 (FAK1) and phosphorylation in response to LPS, and determined the effect of FAK silencing and overexpression on PEC barrier function. We found that LPS induced a greater increase in lung permeability and PEC barrier disruption in the adult mice, despite similar degrees of inflammation and apoptosis. Although baseline expression was similar, LPS increased FAK1 expression in neonatal PEC but increased FAK1 phosphorylation and decreased FAK1 expression in adult PEC. Pharmacologic inhibition of FAK1 accentuated LPS-induced barrier disruption most in adult PEC. Finally, in response to LPS, FAK silencing markedly impaired neonatal PEC barrier function, whereas FAK overexpression preserved adult PEC barrier function. Thus, developmental differences in FAK expression during inflammatory injury serve to preserve neonatal pulmonary endothelial barrier function compared with that of adults and suggest that intrinsic differences in the immature versus pulmonary endothelium, especially relative to FAK1 phosphorylation, may contribute to the improved outcomes of children with ARDS. PMID- 29597356 TI - Complement Factor D protects mice from ethanol-induced inflammation and liver injury. AB - Complement plays a crucial role in microbial defense and clearance of apoptotic cells. Emerging evidence suggests complement is an important contributor to alcoholic liver disease. While complement component 1, Q subcomponent (C1q) dependent complement activation contributes to ethanol-induced liver injury, the role of the alternative pathway in ethanol-induced injury is unknown. Activation of complement via the classical and alternative pathways was detected in alcoholic hepatitis patients. Female C57BL/6J [wild type (WT)], C1q-deficient ( C1qa-/-, lacking classical pathway activation), complement protein 4-deficient ( C4-/-, lacking classical and lectin pathway activation), complement factor D deficient ( FD-/-, lacking alternative pathway activation), and C1qa/FD-/- (lacking classical and alternative pathway activation) mice were fed an ethanol containing liquid diet or pair-fed control diet for 4 or 25 days. Following chronic ethanol exposure, liver injury, steatosis, and proinflammatory cytokine expression were increased in WT but not C1qa-/-, C4-/-, or C1qa/FD-/- mice. In contrast, liver injury, steatosis, and proinflammatory mediators were robustly increased in ethanol-fed FD-/- mice compared with WT mice. Complement activation, assessed by hepatic accumulation of C1q and complement protein 3 (C3) cleavage products (C3b/iC3b/C3c), was evident in livers of WT mice in response to both short-term and chronic ethanol. While C1q accumulated in ethanol-fed FD-/- mice (short term and chronic), C3 cleavage products were detected after short-term but not chronic ethanol. Consistent with impaired complement activation, chronic ethanol induced the accumulation of apoptotic cells and fibrogenic responses in the liver of FD-/- mice. These data highlight the protective role of complement factor D (FD) and suggest that FD-dependent amplification of complement is an adaptive response that promotes hepatic healing and recovery in response to chronic ethanol. NEW & NOTEWORTHY Complement, a component of the innate immune system, is an important pathophysiological contributor to ethanol-induced liver injury. We have identified a novel role for factor D, a component of the alternative pathway, in protecting the liver from ethanol-induced inflammation, accumulation of apoptotic hepatocytes, and profibrotic responses. These data indicate a dual role of complement with regard to inflammatory and protective responses and suggest that accumulation of apoptotic cells impairs hepatic healing/recovery during alcoholic liver disease. PMID- 29597832 TI - Maternal omega-3 PUFA supplementation prevents hyperoxia-induced pulmonary hypertension in the offspring. AB - Pulmonary hypertension (PH) and right ventricular hypertrophy (RVH) affect 16-25% of premature infants with bronchopulmonary dysplasia (BPD), contributing significantly to perinatal morbidity and mortality. Omega-3 polyunsaturated fatty acids (PUFA omega-3) can improve vascular remodeling, angiogenesis, and inflammation under pathophysiological conditions. However, the effects of PUFA omega-3 supplementation in BPD-associated PH are unknown. The present study aimed to evaluate the effects of PUFA omega-3 on pulmonary vascular remodeling, angiogenesis, and inflammatory response in a hyperoxia-induced rat model of PH. From embryonic day 15, pregnant Sprague-Dawley rats were supplemented daily with PUFA omega-3, PUFA omega-6, or normal saline (0.2 ml/day). After birth, pups were pooled, assigned as 12 per litter, randomly assigned to either air or continuous oxygen exposure (fraction of inspired oxygen = 85%) for 20 days, and then euthanized for pulmonary hemodynamic and morphometric analysis. We found that PUFA omega-3 supplementation improved survival, decreased right ventricular systolic pressure and RVH caused by hyperoxia, and significantly improved alveolarization, vascular remodeling, and vascular density. PUFA omega-3 supplementation produced a higher level of total omega-3 in lung tissue and breast milk and was found to reverse the reduced levels of VEGFA, VEGF receptor 2, angiopoietin-1 (ANGPT1), endothelial TEK tyrosine kinase, endothelial nitric oxide synthase, and nitric oxide concentrations in lung tissue and the increased ANGPT2 levels in hyperoxia-exposed rats. The beneficial effects of PUFA omega-3 in improving lung injuries were also associated with an inhibition of leukocyte infiltration and reduced expression of the proinflammatory cytokines IL-1beta, IL 6, and TNF-alpha. These data indicate that maternal PUFA omega-3 supplementation strategies could effectively protect against infant PH induced by hyperoxia.

AB - INTRODUCTION: Nephrolithiasis is one of the most common diseases in urology. According to the EAU Guidelines, a percutaneous nephrolitholapaxy (PNL) is recommended when treating a kidney stone >2 cm. Nowadays, PNL is performed even for smaller stones (<1 cm) using miniaturized instruments. The most challenging part of any PNL is the puncture of the planned site. PNL-novice surgeons need to practice this step in a safe environment with an ideal training model. We developed and evaluated a new, easy to produce, in vitro model for the training of the freehand puncture of the kidney. MATERIALS AND METHODS: Porcine kidneys with ureters were embedded in ballistic gel. Food coloring and preservative agent were added. We used the standard imaging modalities of X-ray and ultrasound to validate the training model. An additional new technique, the iPAD-guided puncture, was evaluated. Five novices and three experts conducted 12 punctures for each imaging technique. Puncture time, radiation dose, and number of attempts to a successful puncture were measured. Mann-Whitney-U, Kruskal-Wallis, and U Tests were used for statistical analyses. RESULTS: The sonography-guided puncture is slightly but not significantly faster than the fluoroscopy-guided puncture and the iPAD-assisted puncture. Similarly, the most experienced surgeon's time for a successful puncture was slightly less than that of the residents, and the experienced surgeons needed the least attempts to perform a successful puncture. In terms of radiation exposure, the residents had a significant reduction of radiation exposure compared to the experienced surgeons. CONCLUSION: The newly developed ballistic gel kidney-puncture model is a good training tool for a variety of kidney-puncture techniques, with good content, construct, and face validity.

AB - BACKGROUND: Concussions are responsible for numerous emergency department visits and hospitalizations among children annually. However, there remains a great deal of confusion about how to prevent and manage concussions in youth. To teach children aged 6 to 8 years about concussion safety, the Centers for Disease Control and Prevention (CDC) created a mobile gaming application called HEADS UP Rocket Blades. This report introduces the game and presents findings on its evaluation. METHODS: The aim of the game is to teach children what a concussion is, its commons signs and symptoms, how to prevent one, and what to do if one occurs. An early version of the game went through two rounds of usability testing with children and parents to obtain initial impressions and make improvements. RESULTS: The first round of usability testing focused on the mechanics of the game. Based on feedback from this session, CDC and the developers simplified the messaging and adjusted the game's level of difficulty. The second round focused on the gaming experience. The children indicated that they enjoyed playing, and nearly all were able to relay at least one learning objective. CONCLUSIONS: Parents and children rated Rocket Blades as a good learning tool and indicated that they would download it for personal use.

Interviewer-administered questionnaires were conducted with 100 Latino farmworkers and 100 nonfarmworker Latino North Carolina residents in 2015 as part of an ongoing community-based participatory research project. Farmworkers had low levels of knowledge about HPV and the HPV vaccine. They had a similar amount of HPV and HPV vaccine knowledge compared to nonfarmworkers. Farmworkers and nonfarmworkers learned about the HPV vaccine from different sources. Adolescent children of farmworkers and nonfarmworkers had low HPV vaccine initiation. However, for children living in the United States with farmworker parents, vaccine initiation was high. To prevent HPV-related cancers and improve health equity, interventions are needed in order to increase HPV education and vaccine initiation among children of Mexican-born farmworkers and nonfarmworkers. Public health programs should look for partners outside the traditional health care setting to reach underserved populations. Other key strategies include promoting catch-up vaccines, improving patient-provider communication, and providing case management services. PMID- 29597874 TI - The Role and Influence of Prostate Cancer Caregivers Across the Care Continuum. AB - BACKGROUND: Black men endure a disproportionate burden of morbidity and mortality related to prostate cancer (CaP). Increasingly family members are assuming the role of providing care and support to family members with chronic disease. Understanding the role and influence of the caregiver is a necessary part of developing resources to assist individuals learning to provide care. AIM: The analysis aimed to explore CaP survivors' perceptions of the role and influence of family caregivers to better understand existing opportunities for improving experiences and outcomes for both the caregiver and the care receiver. DESIGN: Secondary analysis of qualitative interview transcripts. Data were analyzed to explore new inquiries related to CaP survivors' perceptions of family caregivers' role and influence at each stage of care. Content analysis was used to group data into established categories. DATA SOURCE: Data included qualitative interview transcripts with 32 CaP survivors from the Florida Prostate Cancer Care and Survivorship Project. RESULTS: The role of the family caregiver is complex. Caregivers in this community seem to have a significant influence on behavior modification and cues to action for Black men with prostate cancer. According to the men in this group, caregivers functioned as normalizing agents, coordinating care and creating a new normal, throughout the various stages of care and survivorship. CONCLUSIONS: Findings inform areas for future research to develop culturally tailored health promotion programs designed to improve outcomes and address the needs of both the family caregiver and the care receiver across the care continuum.

AB - The years approaching the 70th anniversary of the British National Health Service (NHS) have seen some re-assessment of the role of the Labour party in general, and Minister of Health, Aneurin Bevan in particular, in the creation of the NHS. It is clear that Bevan casts a long shadow over the NHS. In terms of 'history as invocation', Bevan can be invoked in different ways. Put another way, different Bevans cast a variety of shadows. This article explores: Bevan as the embodiment of the NHS; Bevan as rhetoric; Bevan as trust; and Bevan as reassurance. It concludes that Bevan has rightly cast his long shadow over the 70 years of the NHS. However, it is important to recognise the different Bevan reference points for their different reasons. However, there is one surprising omission. As a present to the NHS on its 70th birthday, perhaps it is time to rename this type as a 'Bevan' system? PMID- 29597876 TI - AMPKalpha2 deficiency enhanced susceptibility to ventricular arrhythmias in mice by the role of beta-adrenoceptor signaling. AB - AMP-activated protein kinase-alpha2 is the main catalytic subunit of the heart, which is mainly located in cardiac myocytes. The effect of AMP-activated protein kinase-alpha2 on the cardiac electrophysiology is barely studied. From the previous study, it is possible that AMP-activated protein kinase-alpha2 may have some effect on the electrophysiology of the heart. To prove the hypothesis, we used the AMP-activated protein kinase-alpha2 knockout (AMPKalpha2-/-) mice to estimate the electrophysiological characteristics of AMPKalpha2-/- mice and try to find the mechanism between them. We used AMP-activated protein kinase-alpha2 gene knockout (AMPKalpha2-/-) mice and control wild-type mice as the experimental animals. In the experiment, we measured the monophasic action potential duration and test the inducibility to ventricular arrhythmia in isolated mice heart with and without beta-adrenoceptor antagonist metoprolol. Meanwhile, plasma concentration of catecholamine was collected. We found that AMPKalpha2-/- significantly shortened 90% repolarization of monophasic action potential (MAP) (MAPD90) than wild-type (47.4 +/- 2.6 ms vs. 55.5 +/- 2.4 ms, n = 10, P < 0.05) and were more vulnerable to be induced to ventricular arrhythmias (70% (7/10) vs. 10% (1/10), P < 0.05), accompanied by the higher concentration of catecholamine (epinephrine: 1.75 +/- 0.18 nmol/L vs. 0.68 +/- 0.10 nmol/L n = 10, P < 0.05; norepinephrine: 9.56 +/- 0.71 nmol/L vs. 2.52 +/- 0.31 nmol/L n = 10, P < 0.05). The shortening of MAPD90 and increased inducibility to ventricular arrhythmias of AMPKalpha2-/- could almost be abolished when perfusion with beta-adrenoceptor antagonist metoprolol. It indicated that the beta-adrenoceptor activation resulting from catecholamine release was mainly responsible for the relating changes of electrophysiology of AMPKalpha2-/-. It had great clinical significance, as in patients who had problem with AMP-activated protein kinase alpha2 gene, we might use beta-adrenoceptor antagonists as the prevention of arrhythmias in future. Impact statement As far as we know, this is the first time the role of AMP-activated protein kinase-alpha2 (AMPKalpha2) on the cardiac electrophysiology is explored, and we found that the beta-adrenoceptor activation resulting from catecholamine release was mainly responsible for the changes of electrophysiology related to the absence of AMPKalpha2. This has great clinical significance, as in patients who have problems with AMPKalpha2 gene, we may use beta-adrenoceptor antagonists for the prevention of arrhythmias in future. PMID- 29597877 TI - EB 2017 Article: Interpretation of the lactulose:mannitol test in rural Malawian children at risk for perturbations in intestinal permeability. AB - The dual sugar absorption test, specifically the lactulose:mannitol test, is used to assess gut health. Lactulose absorption is said to represent gut damage and mannitol absorption is used as a measure of normal small bowel function and serves as normalizing factor for lactulose. A underappreciated limitation of this common understanding of the lactulose:mannitol test is that mannitol is not absorbed to any substantial extent by a transcellular process. Additionally, this interpretation of lactulose:mannitol is not consistent with current understanding of paracellular pathways, where three pathway types exist: pore, leak, and unrestricted. Pore and leak pathways are regulated biological constructions of the small bowel barrier, and unrestricted pathways represent micropathological damage. We analyzed 2334 lactulose:mannitol measurements rigorously collected from 622 young rural Malawian children at high risk for poor gut health in light of the pathway model. An alternative method of normalizing for gut length utilizing autopsy data is described. In our population, absorbed lactulose and mannitol are strongly correlated, r = 0.68 P <0.0001, suggesting lactulose and mannitol are traversing the gut barrier via the same pathways. Considering measurements where pore pathways predominate, mannitol flux is about 14 times that of lactulose. As more leak pathways are present, this differential flux mannitol:lactulose falls to 8:1 and when increased numbers of unrestricted pathways are present, the differential flux of mannitol:lactulose is 6:1. There was no substantial correlation between the lactulose:mannitol and linear growth. Given that mannitol will always pass through a given pathway at a rate at least equal to that of lactulose, and lactulose absorption is a composite measure of flux through both physiologic and pathologic pathways, we question the utility of the lactulose:mannitol test. We suggest using lactulose alone is as informative as lactulose:mannitol in a sugar absorption testing in subclinical gut inflammation. Impact statement Our work integrates the standard interpretation of the lactulose:mannitol test (L:M), with mechanistic insight of intestinal permeability. There are three paracellular pathways in the gut epithelium; pore, leak, and unrestricted. Using thousands of L:M measurements from rural Malawian children at risk for increased intestinal permeability, we predict the differential flux of L and M through the pathways. Our findings challenge the traditional notions that little L is absorbed through a normal epithelial barrier and that M is a normalizing factor for L. Our observations are consistent with pore pathways allowing only M to pass. And that substantial amounts of L and M pass through leak pathways which are normal, regulated, cell-junctional adaptations. So M is a composite measure of all pathways, and L is not a measure solely of pathologic gut damage. Using L alone as a probe will yield more information about gut health than L:M.

AB - CRISPR (clustered regularly interspaced short palindromic repeats) genome editing holds promise in the treatment of genetic diseases that currently lack effective long-term therapies. Patients with alpha-1 antitrypsin (AAT) deficiency develop progressive lung disease due to the loss of AAT's antiprotease function and liver disease due to a toxic gain of function of the common mutant allele. However, it remains unknown whether CRISPR-mediated AAT correction in the liver, where AAT is primarily expressed, can correct either or both defects. Here we show that AAV delivery of CRISPR can effectively correct Z-AAT mutation in the liver of a transgenic mouse model. Specifically, we co-injected two AAVs: one expressing Cas9 and another encoding an AAT guide RNA and homology-directed repair template. In both neonatal and adult mice, this treatment partially restored M-AAT in the serum. Furthermore, deep sequencing confirmed both indel mutations and precise gene correction in the liver, permitting careful analysis of gene editing events in vivo. This study demonstrates a proof of concept for the application of CRISPR Cas9 technology to correct AAT mutations in vivo and validates continued exploration of this approach for the treatment of patients with AAT deficiency. PMID- 29597932 TI - Synthesis and antitumor, antityrosinase, and antioxidant activities of xanthone. AB - Ten substituted 1,3-dihydroxyxanthones were synthesized in one step. The yields ranged from 40 to 76%. Compounds 8-10 were first reported. Next, the compounds' in vitro anti-proliferative activities against nine human cancer cell lines, antityrosinase, and antioxidant activities were evaluated. Compounds 1, 4, 6-7, and 9-10 exhibited enhanced cytotoxicity against certain cancer cells. Compounds 2, 8, 9, and 10 inhibited tyrosinase activity to a certain extent. In addition, compound 4 exhibited the best antioxidant activity, which was consistent with theoretical calculations. These results demonstrated that compounds 1-2, 4, and 6 10 were promising leads for further investigation.

AB - The fluoride adsorption potential of chemically modified rice husk and corn cob activated carbon was investigated in batch and column tests. The effect of pH, contact time, initial fluoride concentration and adsorbent dose on the adsorption capacity and efficiency was studied. Batch experimental results were analysed using analysis of variance. The maximum adsorption capacity of 7.9 and 5.8 mg/g and a removal efficiency of 91% and 89% were achieved in batch tests, respectively, for rice husk and corn cob activated carbon. The adsorption data and kinetic model fitted well to the Langmuir isotherm and pseudo-second-order kinetics, respectively. Fluoride adsorption was governed by both intraparticle diffusion and surface or film diffusion for both rice husk and corn cob activated carbon. Continuous tests were carried out using three columns packed with 100% rice husk activated carbon, 100% corn cob activated carbon and 50% rice husk + 50% corn cob activated carbon. The breakthrough adsorption capacities were found to be 7.9, 5.0 and 5.2 mg/g, respectively. The results were analysed using the Thomas model, which yielded adsorption capacities of 11, 8.1 and 9.4 mg/g, respectively, for the three columns investigated.

PMID- 29598007 TI - AAV6-Mediated IL-10 Expression in the Lung Ameliorates Bleomycin-Induced Pulmonary Fibrosis in Mice. AB - Idiopathic pulmonary fibrosis (IPF) is a fibroproliferative disorder with limited therapeutic options. An aberrant wound healing process in response to repetitive lung injury has been suggested for its pathogenesis, and a number of cytokines including transforming growth factor beta1 play pivotal roles in the induction and progression of fibrosis. Thus, the regulation of these pro-inflammatory conditions may reduce the progression of IPF and ameliorate its symptoms in patients. Interleukin-10 (IL-10), a pleiotropic cytokine, exerts anti inflammatory and anti-fibrotic effects in numerous biological settings. In the present study, we investigated the preventive effects of IL-10 on bleomycin induced pulmonary fibrosis in mice with the continuous expression of this cytokine via an adeno-associated virus serotype 6 vector. Mice were administered the adeno-associated virus serotype 6 vector encoding mouse IL-10 by intratracheal injection, and osmotic minipumps containing bleomycin were subcutaneously implanted seven days later. Lung histology and the expression levels of pro-inflammatory cytokines and fibrogenic cytokines were then analyzed. In mice exhibiting persistent IL-10 expression on day 35, the number of infiltrated inflammatory cells and the development of fibrosis in lung tissues were significantly reduced. Increases in transforming growth factor beta1 and decreases in IFN-gamma were also suppressed in treated animals, with changes in these cytokines playing important roles in the pathogenesis of pulmonary fibrosis. Furthermore, IL-10 significantly improved survival in bleomycin-induced mice. Our results provide insights into the potential benefit of the anti fibrotic effects of IL-10 as a novel therapeutic approach for IPF. PMID- 29598152 TI - Secondary adherence to non-vitamin-K antagonist oral anticoagulants in patients with atrial fibrillation in Sweden and the Netherlands. AB - OBJECTIVE: There is limited evidence on patients' adherence and the impact of the prescribed dosing regimen in non-vitamin-K oral anticoagulants (NOACs). We aimed to assess secondary adherence to NOACs and to determine the impact of the dosing regimen in patients with atrial fibrillation. METHODS: Patients using a NOAC between 2009 and 2013 were identified from the nation-wide Swedish Prescribed Drug Register and the Dutch regional IADB.nl database. Patients using a consistent dosage for at least 180 consecutive days were included. Adherence was calculated using the medication possession ratio (MPR) and adjusted for overlapping dates. Adherence was defined as a MPR >=0.8. Sensitivity analyses were performed using a MPR >=0.9. Logistic regression was performed to compare secondary adherence and to explore the influence of the dosing regimen. RESULTS: A total of 5254 Swedish and 430 Dutch NOAC users were included. The mean MPR was 96.0% (SD 7.8%) in Sweden and 95.1% (SD 10.1%) in the Netherlands. Multivariable logistic regression analysis showed that a twice daily regimen had a lower likelihood of being secondary adherent compared to a once daily regimen in Sweden (odds ratio [OR] 0.21 [95% CI 0.12-0.35]). LIMITATIONS: The influence of selection bias introduced by the inclusion criterion of >=2 dispensations covering at least 180 days could not be excluded. CONCLUSIONS: This study demonstrated that secondary adherence was high in this specific setting among patients with at least two initial dispensations of a NOAC covering a minimum of 180 days. The use of NOACs in a once daily regimen showed higher adherence compared to a twice daily regimen.

AB - Spinal muscular atrophy (SMA) is a kind of neuromuscular disease characterized by progressive motor neuron loss in the spinal cord. It is caused by mutations in the survival motor neuron 1 (SMN1) gene. SMN1 has a paralogous gene, survival motor neuron 2 (SMN2), in humans that is present in almost all SMA patients. The generation and genetic correction of SMA patient-specific induced pluripotent stem cells (iPSCs) is a viable, autologous therapeutic strategy for the disease. Here, c-Myc-free and non-integrating iPSCs were generated from the urine cells of an SMA patient using an episomal iPSC reprogramming vector, and a unique crRNA was designed that does not have similar sequences (<=3 mismatches) anywhere in the human reference genome. In situ gene conversion of the SMN2 gene to an SMN1 like gene in SMA-iPSCs was achieved using CRISPR/Cpf1 and single-stranded oligodeoxynucleotide with a high efficiency of 4/36. Seamlessly gene-converted iPSC lines contained no exogenous sequences and retained a normal karyotype. Significantly, the SMN expression and gems localization were rescued in the gene converted iPSCs and their derived motor neurons. This is the first report of an efficient gene conversion mediated by Cpf1 homology-directed repair in human cells and may provide a universal gene therapeutic approach for most SMA patients. PMID- 29598154 TI - Sorption of antibiotics onto montmorillonite and kaolinite: competition modelling. AB - Antibiotic contaminants, which are generally present in bi-solute systems, can be competitively adsorbed onto clays. Single- and bi-solute sorptions of sulfadiazine (SDZ) and ciprofloxacin (CIP) onto montmorillonite and kaolinite were investigated at pH values of 5 and 8. Freundlich and Langmuir models were used and fit the experimental data well for single-solute sorption. The sorption isotherms were nonlinear (NF = 0.265-0.730), and the maximum sorption capacities (qmL) of the SDZ and CIP onto montmorillonite were higher than those onto kaolinite. The octanol-water distribution ratio (Dow), cation exchange capacity (CEC), Brunauer-Emmett-Teller (BET) surface area (ABET), pore size, point of zero charge (pHPZC), and basal spacing predominantly affected the Freundlich constant (KF) and qmL of SDZ0 and CIP+ at pH 5 more than SDZ- and CIP+/- at pH 8. For bi solute sorption, the presence of CIP inhibited the SDZ sorption onto montmorillonite and kaolinite. Competitive sorption models such as Sheindorf Rebhun-Sheintuch (SRS), Murali-Aylmore (M-A) and the modified extended Langmuir model (MELM) were used; of these, the MELM provided the best prediction with SDZ sorption onto montmorillonite at pH 8 and CIP onto kaolinite at pH 5 and 8 in SDZ/CIP system occurring synergistically, whereas others occurred antagonistically. The distribution coefficient (Kd) of the bi-solute sorption decreased with increasing pH in the order cationic > neutral > anionic for SDZ and cationic > zwitterionic > anionic for CIP, which resembled the Kd of single solute sorption. Fourier transform infrared spectroscopy (FT-IR) spectra indicated that amine in SDZ and keto oxygen in CIP were responsible for the interactions with the montmorillonite and kaolinite. PMID- 29598155 TI - Two Are No Different Than One: Ureteral Duplication Appears to Have No Effect on Ureteroscopy Outcomes. AB - INTRODUCTION: Ureteral duplication is the most common ureteral anomaly, occurring in 0.6%-0.7% of the population. Our objective was to compare urolithiasis treatment outcomes in patients with and without ureteral duplication. METHODS: Patients with ureteral duplication who underwent ureteroscopy (URS) were identified in a stone registry at a high-volume, tertiary care center from 1998 to 2015. Preoperative, intraoperative, and postoperative data were collected retrospectively. A 1:1 control cohort of patients without duplication was identified, matched by stone location and size, as well as age, body mass index (BMI), and gender. Clinical data and outcomes were compared between duplication and control groups, between partial and complete duplication groups, and between patients in whom duplication was identified intraoperatively vs known preoperatively. RESULTS: Fifty patients with ureteral duplication who underwent URS were identified and were matched to 50 control patients. Patients with ureteral duplication required longer operative time (55 minutes vs 38.5 minutes, p = 0.022). Ureteral duplication had no effect on stone-free rates or need for additional procedures. High-grade (Clavien 4-5) complications were similar in both groups (4% vs 4%). Location of ureteral duplication and preoperative knowledge of ureteral duplication did not affect operative time or stone-free rates. CONCLUSIONS: Patients with ureteral duplication undergoing URS for urinary stone disease have longer operative times. Preoperative knowledge of ureteral duplication appears to have no significant effect on URS's safety or efficacy. In patients without a prior diagnosis of ureteral duplication, our data suggest that intraoperative detection via endoscopy and fluoroscopy is sufficient to safely and completely treat stone disease. PMID- 29598224 TI - Integrating Spiritual Care During Interprofessional Simulation for Baccalaureate Nursing Students. AB - Interprofessional educational experiences for baccalaureate nursing students are essential to prepare them for interprofessional communication and collaborative interprofessional teamwork. The aim of this descriptive qualitative study was to understand the experience of baccalaureate nursing students utilizing the hospital chaplain while caring for a suicidal patient in the emergency department during simulation. The need for interprofessional education is documented in the literature, but there are very few comprehensive, successful projects integrating spiritual care for nurse educators to use as models. This project can serve as a model of a successful interprofessional education initiative involving preprofessional nursing students and chaplain services. Overall, nursing students found the learning experience to be beneficial in preparation for professional practice on a collaborative interprofessional health care team. PMID- 29598225 TI - A Qualitative Study of a Compassion, Presence, and Resilience Training for Oncology Interprofessional Teams. AB - The well-being of health care providers may be challenged by their work, with evidence that oncology health care providers are a high-risk group for burnout. The present qualitative pilot study evaluated a mindfulness-based group intervention, referred to as Compassion, Presence, and Resilience Training (CPR T), for oncology interprofessional teams. The purpose of this study was to elucidate the subjective experience of oncology health care providers receiving CPR-T and their perceptions of its benefits, risks, or challenges. The CPR-T was delivered to providers from two oncology teams in a large cancer center in Canada. Ten of these providers participated in semistructured interviews 1 to 5 months after completing the CPR-T. The interview transcripts were coded using a thematic analysis strategy. Five benefits of the CPR-T were identified: learning to pause, acquiring a working definition of stress and self-care, becoming fully present, building self-compassion, and receiving organizational acknowledgment and recognition of stress. In addition, two participant-identified challenges were recognized: sharing vulnerability within interprofessional teams and committing to a sitting meditation practice. These findings demonstrate positive transformations as a result of the CPR-T, as well as important challenges, and have important implications for holistic health care practice in oncology. Further research is necessary to validate the findings of this explorative study. PMID- 29598432 TI - Childhood Trauma and Psychopathic Features Among Juvenile Offenders. AB - Despite growing interest in psychopathic personality features in juvenile offenders, few studies have examined the relationship between childhood trauma and psychopathy. The present study utilized two datasets: 253 adolescents in a residential facility for juvenile offenders in Pennsylvania and 723 institutionalized delinquents in Missouri. Zero-order correlations and linear regression techniques were employed for boys and girls to examine the relationships between trauma, assessed using the Massachusetts Youth Screening Instrument Version 2 (MAYSI-2) Traumatic Experiences Scale and the Childhood Trauma Questionnaire (CTQ), and psychopathy as measured by the Youth Psychopathic Traits Inventory (YPI) and the Psychopathic Personality Inventory-Short Form (PPI SF). Results indicate that psychopathy is significantly correlated with childhood trauma. For the Missouri data, trauma significantly predicted psychopathy scores for both boys and girls. These results suggest that nuanced understanding of traumatic history of these adolescents may not only be a pathway to psychopathy but also a critical part of their overall assessment and treatment plan. PMID- 29598451 TI - Novel drug discovery strategies for atherosclerosis that target necrosis and necroptosis. AB - INTRODUCTION: Formation and enlargement of a necrotic core play a pivotal role in atherogenesis. Since the discovery of necroptosis, which is a regulated form of necrosis, prevention of necrotic cell death has become an attractive therapeutic goal to reduce plaque formation. Areas covered: This review highlights the triggers and consequences of (unregulated) necrosis and necroptosis in atherosclerosis. The authors discuss different pharmacological strategies to inhibit necrotic cell death in advanced atherosclerotic plaques. Expert opinion: Addition of a necrosis or necroptosis inhibitor to standard statin therapy could be a promising strategy for primary prevention of cardiovascular disease. However, a necrosis inhibitor cannot block all necrosis stimuli in atherosclerotic plaques. A necroptosis inhibitor could be more effective, because necroptosis is mediated by specific proteins, termed receptor-interacting serine/threonine-protein kinases (RIPK) and mixed lineage kinase domain-like pseudokinase (MLKL). Currently, only RIPK1 inhibitors have been successfully used in atherosclerotic mouse models to inhibit necroptosis. However, because RIPK1 is involved in both necroptosis and apoptosis, and also RIPK1-independent necroptosis can occur, we feel that targeting RIPK3 and MLKL could be a more attractive therapeutic approach to inhibit necroptosis. Therefore, future challenges will consist of developing RIPK3 and MLKL inhibitors applicable in both preclinical and clinical settings. PMID- 29598751 TI - Threat Bias and Emotion Recognition in Victims of IPV. AB - Although there is growing evidence of the association between threat bias and psychopathology in many trauma-exposed populations, there are few studies with intimate partner violence (IPV) victims. The present study assessed threat bias in IPV victims. It also examined potential differences in facial recognition ability between victims and nonvictims. Participants were 153 female college students currently in a dating relationship. Participants completed demographic and abuse severity measures. They then completed a dot-probe task to assess threat bias, and a facial expression recognition task to assess speed and accuracy of recognition. Approximately 32% of the students sampled were currently in a physically abusive relationship. Results indicated that IPV victims had a bias toward fearful faces, and showed worse recognition of happy faces than nonvictims. These data suggest that the psychological impact of threat bias might vary temporally. Vigilance during threat may serve as a protective mechanism, whereas postthreat vigilance might be associated with psychopathology. Researchers should carefully consider the presence of threat bias in victim samples and include other victim groups in future assessments of threat bias. It will be important to test these relationships in other IPV victim samples, such as help-seeking victims and other community living victims.

PMID- 29598691 TI - Intrauterine Hyperglycemia Is Associated with an Impaired Postnatal Response to Oxidative Damage. AB - Hyperglycemia and other adverse exposures early in life that reprogram stem cells may lead to long-lasting phenotypic influences over the lifetime of an individual. Hyperglycemia and oxidative stress cause DNA damage when they exceed the protective capabilities of the cell, in turn affecting cellular function. DNA damage in response to hyperglycemia and oxidative stress was studied in human umbilical cord mesenchymal stem cells (hUC-MSCs) from large-for-gestational-age (LGA) infants of mothers with gestational diabetes mellitus (LGA-GDM) and control subjects. We tested the response of these cells to hyperglycemia and oxidative stress, measuring reactive oxygen species (ROS) levels and antioxidant enzyme activities. We find that hUC-MSCs from LGA-GDM infants have increased DNA damage when exposed to oxidative stress. With the addition of hyperglycemic conditions, these cells have an increase in ROS and a decrease in antioxidant glutathione peroxidase (GPx) activity, indicating a mechanism for the increased ROS and DNA damage. This study demonstrates that a memory of in utero hyperglycemia, mediated through downregulation of GPx activity, leads to an increased susceptibility to oxidative stress. The alteration of GPx function in self-renewing stem cells, can mediate the effect of intrauterine hyperglycemia to be propagated into adulthood and contribute to disease susceptibility. PMID- 29598752 TI - A Neglected Population: Media Consumption, Perceived Risk, and Fear of Crime Among International Students. AB - The 4.5 million international students worldwide bring in multifold benefits to the advancement of culture, economy, and national security in education host countries. Surprisingly, few prior studies have explored international students' fear of crime, which may harm their mental and physical health and undermine their educational achievements. The current study aims to fill in this research void by investigating international students' fear of crime in line with the cultivation theoretical framework, which postulates that media consumption cultivates fear of crime. The analyses draw on a sample of 398 international students attending nine different public and private universities across the United States. Using structural equation modeling (SEM), I investigate the extent and correlates of students' fear of crime. The findings reveal that international students are more fearful in the United States than in their home countries. SEM results show that controlling for students' fear in their home countries, attention paid to crime news is positively related to fear in the United States, through perceived victimization risk. The SEM results also suggest that exposure to non-U.S. social media (e.g., WeChat and Weibo) is positively related to respondents' fear of crime, whereas exposure to U.S. social media (e.g., Facebook and Twitter) is not related to fear of crime. The current study highlights the importance of studying the impact of fear of crime and social media use on international students.

AB - The relationship between housing and HIV infection is complex. On one hand, poor housing arrangements may affect the health of persons living with HIV/AIDS (PLWHAs). On the other hand, PLWHAs may be more likely to live in substandard homes because of their health. We used qualitative in-depth individual interviews of 38 PLWHAs attending voluntary counseling services at two government hospitals in the Lower Manya Krobo District (LMKD) in the Eastern region of Ghana to examine their housing and health outcomes. Results show that the majority of PLWHAs lived in homes that lacked basic amenities, were overcrowded, had structural deficiencies, and were noisy and dirty. They suffered from poor housing conditions mainly because of their HIV serostatus, as this affected their ability to finance adequate homes, while HIV-related stigmatization led to eviction from either family homes or rented facilities. PMID- 29598770 TI - Living a Life Full of Pain: Older Pain Clinic Patients' Experience of Living With Chronic Low Back Pain. AB - Chronic low back pain (CLBP) is older adults' most common pain complaint and is associated with many physical and psychosocial consequences, which have been quantitatively examined. However, little research has qualitatively examined the experience itself of CLBP in later life. Study objective was to understand older adults' lived CLBP experience. Guided by van Manen's phenomenological method, 21 pain clinic patients aged 66 to 83 completed semistructured interviews. Under the main theme "living a life full of pain," results are reflected in four existential subthemes: (a) Corporeality: The pain is relentless and constantly monitored, (b) Temporality: To live with pain is to live by pacing day and night, (c) Relationality: Pain creates limits that can be tested or obeyed, and (d) Spatiality: Manipulating the space around me to accommodate the pain. Findings improve understanding of the patient experience of late life CLBP and highlights the importance of empathy and patient-centeredness when treating older adults.

The miRNAs targeting the promoter region and coding region of the heparanase gene were designed and synthesized. We transfected four recombinant miRNA vectors into GBC SD. We performed the wound healing assays and invasion assays. The result shows that the heparanase expression was significantly decreased by recombinant vectors in transfected GBC-SD cells (p < 0.01), of which pmiR-Hpa-2 showed best interference effect (p < 0.05).

AB - Often described in such terms as a "revolution" and a "game-changer" for the behavioral health sector in the United States, the Affordable Care Act has helped to enhance coverage for mental health and substance use disorders while encouraging service system innovations at the organizational level. However, tens of millions of Americans still lack health insurance, insurance companies are resisting the implementation of parity coverage rules, and inequalities in the financing and organization of care continue to worsen in key respects. This article examines these difficulties and their political-economic nature, highlighting the need for a single-payer framework if the task of reform is to be fulfilled.

AB - The English National Health Service (NHS) has suffered from a democratic deficit since its inception. Democratic accountability was to be through ministers to Parliament, but ministerial control over and responsibility for the NHS were regarded as myths. Reorganizations and management and market reforms, in the neoliberal era, have centralized power within the NHS. However, successive governments have sought to reduce their responsibility for health care through institutional depoliticization, to shift blame, facilitated through legal changes. New Labour's creation of the National Institute for Clinical Excellence (NICE) and Monitor were somewhat successful in reducing ministerial culpability regarding health technology regulation and foundation trusts, respectively. The Conservative-Liberal Democrat coalition created NHS England to reduce ministerial culpability for health care more generally. This is pertinent as the NHS is currently being undermined by inadequate funding and privatization. However, the public has not shifted from blaming the government to blaming NHS England. This indicates limits to the capacity of law to legitimize changes to social relations. While market reforms were justified on the basis of empowering patients, I argue that addressing the democratic deficit is a preferable means of achieving this goal.

PMID- 29598810 TI - Patterns of Health Care Utilization for Noncommunicable Diseases in a Transitional European Country: Results From the National Health Survey. AB - This study aimed to assess possible differences in health services utilization among people living with noncommunicable diseases (NCDs) in the Republic of Srpska (RS), Bosnia and Herzegovina, with special reference to NCD multimorbidity. In addition, the relationship between self-perceived health and health care utilization was assessed. Data were retrieved from the 2010 National Health Survey. A cross-sectional study design was used. A total of 4,673 persons aged 18 years and older were identified in the households, of which 4,128 were interviewed. Logistic regression analyses were used to estimate the effects of NCDs on health care utilization in RS. Respondents with NCD multimorbidity more frequently visited family physicians (odds ratio [OR], 2.74; 95% confidence interval [CI], 2.34 - 3.19), dentists (OR, 1.57; CI, 1.28 - 1.92), private doctors (OR, 2.14; CI, 1.74 - 2.64), and urgent care departments (OR, 2.30; CI, 1.75 - 3.03) than their counterparts without NCDs. They also had more hospital admissions (OR, 2.03; CI, 1.56 - 2.64). This is the first study to address the relationship between health care utilization and NCDs in the population of RS. Further research is needed to explore how best to organize health care to meet the needs of people in RS with NCDs, especially with NCD multimorbidity.

AB - This study investigates the rolling and drag resistance parameters and bicycle and cargo masses of typical urban cyclists. These factors are important for modelling of cyclist speed, power and energy expenditure, with applications including exercise performance, health and safety assessments and transportation network analysis. However, representative values for diverse urban travellers have not been established. Resistance parameters were measured utilizing a field coast-down test for 557 intercepted cyclists in Vancouver, Canada. Masses were also measured, along with other bicycle attributes such as tire pressure and size. The average (standard deviation) of coefficient of rolling resistance, effective frontal area, bicycle plus cargo mass, and bicycle-only mass were 0.0077 (0.0036), 0.559 (0.170) m2, 18.3 (4.1) kg, and 13.7 (3.3) kg, respectively. The range of measured values is wider and higher than suggested in existing literature, which focusses on sport cyclists. Significant correlations are identified between resistance parameters and rider and bicycle attributes, indicating higher resistance parameters for less sport-oriented cyclists. The findings of this study are important for appropriately characterising the full range of urban cyclists, including commuters and casual riders. PMID- 29598812 TI - Preface.

AB - BACKGROUND: Globally, childhood diarrhea is amongst the most prevalent health problems and accounts for 9% of all deaths in children under-five. In Ethiopia, childhood diarrhea is a major public health problem in which the prevalence ranges from 13.5 to 30.5% and experienced by multiple factors. Although health extension program has been implementing for couples of years; diarrheal disease remains the second cause of morbidity and continues an important public health problem in the study district. Thus, this study assessed determinants of diarrheal disease among under-five children in the Medebay Zana district, northwest Tigray, Ethiopia, 2015. METHOD: A community based case-control study was used. A multistage sampling procedure was employed to enroll the study participants. Data were collected using face to face administered questionnaire. The collected data were entered into Epi Info version 3.5.4 and exported to SPSS Version 21 for analysis. Frequencies with percentages were computed using univariate analysis. Finally, logistic regression model was fitted to identify factors associated with childhood diarrhea where P-values of less than 0.05 were considered statistically significant. RESULTS: Socio-demographic factors such as low maternal educational level [AOR = 2.88, 95% CI (1.70, 4.88)], being index child of older age, households with >=3 number of children under-five [AOR = 4.05, 95% CI (1.91, 8.60)] and maternal history of diarrhea [AOR = 2.10, 95% CI (1.09, 4.05)] were statistically associated with childhood diarrhea. This study also revealed that child feeding practice; not exclusively breastfed [AOR = 4.84, 95% CI (2.21, 10.60)] and initiation of complementary feeding above 6 months [AOR = 1.78, 95% CI (1.09, 2.92)] were statistically associated with outcome variable. Environmental and behavioral practices such as unavailability toilet facility [AOR = 2.10, 95% CI (1.34, 3.30)], improper solid waste disposal [AOR = 2.29, 95% CI (1.53, 3.44)] and unprotected drinking water [AOR = 1.83, 95% CI (1.12, 2.98)] were also found significant factors of childhood diarrhea. CONCLUSION: Maternal educational status, age of index child, number of < 5 children, child feeding practices, maternal history of diarrhea, toilet facility, solid waste disposal and household drinking water were found determinants of childhood diarrhea. These findings have policy implications and insight the strengthening for health intervention programs. PMID- 29598817 TI - Hepatitis B in Moroccan-Dutch: a quantitative study into determinants of screening participation. AB - BACKGROUND: In November 2016, the Dutch Health Council recommended hepatitis B (HBV) screening for first-generation immigrants from HBV endemic countries. However, these communities show relatively low attendance rates for screening programmes, and our knowledge on their participation behaviour is limited. We identified determinants associated with the intention to request an HBV screening test in first-generation Moroccan-Dutch immigrants. We also investigated the influence of non-refundable costs for HBV screening on their intention. METHODS: Offline and online questionnaires were distributed among first- and second/third generation Moroccan-Dutch immigrants using respondent-driven sampling. Random forest analyses were conducted to determine which determinants had the greatest impact on (1) the intention to request an HBV screening test on one's own initiative, and (2) the intention to participate in non-refundable HBV screening at ?70,-. RESULTS: Of the 379 Moroccan-Dutch respondents, 49.3% intended to request a test on their own initiative, and 44.1% were willing to attend non refundable screening for ?70,-. Clarity regarding infection status, not having symptoms, fatalism, perceived self-efficacy, and perceived risk of having HBV were the strongest predictors to request a test. Shame and stigma, fatalism, perceived burden of screening participation, and social influence of Islamic religious leaders had the greatest predictive value for not intending to participate in screening at ?70,- non-refundable costs. Perceived severity and possible health benefit were facilitators for this intention measure. These predictions were satisfyingly accurate, as the random forest method retrieved area under the curve scores of 0.72 for intention to request a test and 0.67 for intention to participate in screening at ?70,- non-refundable costs. CONCLUSIONS: By the use of respondent-driven sampling, we succeeded in studying screening behaviour among a hard-to-reach minority population. Despite the limitations associated with correlated data and the sampling method, we recommend to (1) incorporate clarity regarding HBV status, (2) stress the risk of an asymptomatic infection, (3) emphasise mother-to-child transmission as the main transmission route, and (4) team up with Islamic religious leaders to help decrease elements of fatalism, shame, and stigma to enhance screening uptake of Moroccan immigrants in the Netherlands. PMID- 29598816 TI - Annexin A2-mediated cancer progression and therapeutic resistance in nasopharyngeal carcinoma. AB - Nasopharyngeal carcinoma (NPC) is a head and neck cancer with poor clinical outcomes and insufficient treatments in Southeast Asian populations. Although concurrent chemoradiotherapy has improved recovery rates of patients, poor overall survival and low efficacy are still critical problems. To improve the therapeutic efficacy, we focused on a tumor-associated protein called Annexin A2 (ANXA2). This review summarizes the mechanisms by which ANXA2 promotes cancer progression (e.g., proliferation, migration, the epithelial-mesenchymal transition, invasion, and cancer stem cell formation) and therapeutic resistance (e.g., radiotherapy, chemotherapy, and immunotherapy). These mechanisms gave us a deeper understanding of the molecular aspects of cancer progression, and further provided us with a great opportunity to overcome therapeutic resistance of NPC and other cancers with high ANXA2 expression by developing this prospective ANXA2 targeted therapy. PMID- 29598818 TI - Signal peptides for recombinant protein secretion in bacterial expression systems. AB - The secretion of biotechnologically or pharmaceutically relevant recombinant proteins into the culture supernatant of a bacterial expression host greatly facilitates their downstream processing and significantly reduces the production costs. The first step during the secretion of a desired target protein into the growth medium is its transport across the cytoplasmic membrane. In bacteria, two major export pathways, the general secretion or Sec pathway and the twin-arginine translocation or Tat pathway, exist for the transport of proteins across the plasma membrane. The routing into one of these alternative protein export systems requires the fusion of a Sec- or Tat-specific signal peptide to the amino terminal end of the desired target protein. Since signal peptides, besides being required for the targeting to and membrane translocation by the respective protein translocases, also have additional influences on the biosynthesis, the folding kinetics, and the stability of the respective target proteins, it is not possible so far to predict in advance which signal peptide will perform best in the context of a given target protein and a given bacterial expression host. As outlined in this review, the most promising way to find the optimal signal peptide for a desired protein is to screen the largest possible diversity of signal peptides, either generated by signal peptide variation using large signal peptide libraries or, alternatively, by optimization of a given signal peptide using site-directed or random mutagenesis strategies. PMID- 29598819 TI - HbA1c variability and diabetic peripheral neuropathy in type 2 diabetic patients. AB - BACKGROUND: Diabetic complications may be associated with impaired time-dependent glycemic control. Therefore, long-term glycemic variability, assessed by variations in haemoglobin A1c (HbA1c), may be a potential risk factor for microvascular complications, such as diabetic peripheral neuropathy (DPN). We investigated the association of HbA1c variability with DPN in patients with type 2 diabetes. METHODS: In this cross-sectional study, 563 type 2 diabetic patients who had been screened for DPN and undergone quarterly HbA1c measurements during the year preceding enrolment were recruited. DPN was confirmed in patients displaying both clinical manifestations of neuropathy and abnormalities in a nerve conduction evaluation. HbA1c variability was assessed by the coefficient of variation of HbA1c (CV-HbA1c), and the mean of HbA1c (M-HbA1c) was calculated. In addition, medical history and clinical data were collected. RESULTS: Among the recruited patients, 18.1% (n = 102) were found to have DPN, and these patients also presented with a higher CV-HbA1c than the patients without DPN (p < 0.001). The proportion of patients with DPN increased significantly from 6.9% in the first to 19.1% in the second and 28.5% in the third tertile of CV-HbA1c (p for trend < 0.001). After adjusting for initial HbA1c, M-HbA1c and other clinical factors via multiple logistic regression analysis, the odds ratios (ORs) for DPN in the second and third versus those in the first CV-HbA1c tertile were 3.61 (95% CI 1.62-8.04) and 6.48 (2.86-14.72), respectively. The area under the receiver operating characteristic (ROC) curve of CV-HbA1c was larger than that of M-HbA1c, at 0.711 (95% CI 0.659-0.763) and 0.662 (0.604-0.721), respectively. ROC analysis also revealed that the optimal cutoff value of CV-HbA1c to indicate DPN was 15.15%, and its corresponding sensitivity and specificity were 66.67% and 65.73%, respectively. CONCLUSIONS: Increased HbA1c variability is closely associated with DPN in type 2 diabetic patients and could be considered as a potent indicator for DPN in these patients. PMID- 29598820 TI - The role of obesity in carotid plaque instability: interaction with age, gender, and cardiovascular risk factors. AB - BACKGROUND: In the last decade, several studies have reported an unexpected and seemingly paradoxical inverse correlation between BMI and incidence of cardiovascular diseases. This so called "obesity paradox effect" has been mainly investigated through imaging methods instead of histologic evaluation, which is still the best method to study the instability of carotid plaque. Therefore, the purpose of our study was to evaluate by histology the role of obesity in destabilization of carotid plaques and the interaction with age, gender and other major cerebrovascular risk factors. METHODS: A total of 390 carotid plaques from symptomatic and asymptomatic patients submitted to endarterectomy, for whom complete clinical and laboratory assessment of major cardiovascular risk factors was available, were studied by histology. Patients with a BMI >= 30.0 kg/m2 were considered as obese. Data were analyzed by multivariate logistic regression and for each variable in the equation the estimated odds ratio (OR) was calculated. RESULTS: Unstable carotid plaque OR for obese patients with age < 70 years was 5.91 (95% CI 1.17-29.80), thus being the highest OR compared to that of other risk factors. Unstable carotid plaque OR decreased to 4.61 (95% CI 0.54-39.19) in males >= 70 years, being only 0.93 (95% CI 0.25-3.52) among women. When obesity featured among metabolic syndrome risk factors, the OR for plaque destabilization was 3.97 (95% CI 1.81-6.22), a significantly higher value compared to OR in non obese individuals with metabolic syndrome (OR = 1.48; 95% CI 0.86-2.31). Similar results were obtained when assessing the occurrence of acute cerebrovascular symptoms. CONCLUSIONS: Results from our study appear to do not confirm any paradoxical effect of obesity on the carotid artery district. Conversely, obesity is confirmed to be an independent risk factor for carotid plaque destabilization, particularly in males aged < 70 years, significantly increasing such risk among patients with metabolic syndrome. PMID- 29598821 TI - Association between the DNA methylations of POMC, MC4R, and HNF4A and metabolic profiles in the blood of children aged 7-9 years. AB - BACKGROUND: Proopiomelanocortin (POMC), melanocortin 4 receptor (MC4R), and hepatocyte nuclear factor 4 alpha (HNF4A) are closely associated with weight gain and metabolic traits. In a previous study, we demonstrated associations between the methylations of POMC, MC4R, and HNF4A and metabolic profiles at birth. However, little is known about these associations in obese children. To evaluate the clinical utility of epigenetic biomarkers, we investigated to determine whether an association exists between the methylations of POMC, MC4R, and HNF4A and metabolic profiles in blood of normal weight and overweight and obese children. METHODS: We selected 79 normal weight children and 41 overweight and obese children aged 7-9 years in the Ewha Birth and Growth Cohort study. POMC methylation levels at exon 3, and MC4R and HNF4A methylation levels in promoter regions were measured by pyrosequencing. Serum glucose, total cholesterol (TC), triglyceride, high-density lipoprotein cholesterol (HDL-c), and insulin levels were analyzed using a biochemical analyzer and an immunoradiometric assay. Partial correlation and multiple regression analysis were used to assess relationships between POMC, MC4R, and HNF4A methylation levels and metabolic profiles. RESULTS: Significant correlations were found between POMC methylation and HDL-c levels, and between HNF4A methylation and both TC and HDL-c levels. Interestingly, associations were found between POMC methylation status and HDL-c levels, and between HNF4A methylation status and TC levels independent of body mass index. CONCLUSIONS: These findings show that POMC, MC4R, and HNF4A methylation status in the blood of children are associated with metabolic profiles. Therefore, we suggest that the DNA methylation status might serve as a potential epigenetic biomarkers of metabolic syndrome. PMID- 29598822 TI - Dimethyl fumarate attenuates reactive microglia and long-term memory deficits following systemic immune challenge. AB - BACKGROUND: Systemic inflammation is associated with increased cognitive decline and risk for Alzheimer's disease. Microglia (MG) activated during systemic inflammation can cause exaggerated neuroinflammatory responses and trigger progressive neurodegeneration. Dimethyl fumarate (DMF) is a FDA-approved therapy for multiple sclerosis. The immunomodulatory and anti-oxidant properties of DMF prompted us to investigate whether DMF has translational potential for the treatment of cognitive impairment associated with systemic inflammation. METHODS: Primary murine MG cultures were stimulated with lipopolysaccharide (LPS) in the absence or presence of DMF. MG cultured from nuclear factor (erythroid-derived 2) like 2-deficient (Nrf2 -/- ) mice were used to examine mechanisms of DMF actions. Conditioned media generated from LPS-primed MG were used to treat hippocampal neuron cultures. Adult C57BL/6 and Nrf2 -/- mice were subjected to peripheral LPS challenge. Acute neuroinflammation, long-term memory function, and reactive astrogliosis were examined to assess therapeutic effects of DMF. RESULTS: DMF suppressed inflammatory activation of MG induced by LPS. DMF suppressed NF-kappaB activity through Nrf2-depedent and Nrf2-independent mechanisms in MG. DMF treatment reduced MG-mediated toxicity towards neurons. DMF suppressed brain derived inflammatory cytokines in mice following peripheral LPS challenge. The suppressive effect of DMF on neuroinflammation was blunted in Nrf2 -/- mice. Importantly, DMF treatment alleviated long-term memory deficits and sustained reactive astrogliosis induced by peripheral LPS challenge. DMF might mitigate neurotoxic astrocytes associated with neuroinflammation. CONCLUSIONS: DMF treatment might protect neurons against toxic microenvironments produced by reactive MG and astrocytes associated with systemic inflammation. PMID- 29598823 TI - Full-length mRNA sequencing uncovers a widespread coupling between transcription initiation and mRNA processing. AB - BACKGROUND: The multifaceted control of gene expression requires tight coordination of regulatory mechanisms at transcriptional and post-transcriptional level. Here, we studied the interdependence of transcription initiation, splicing and polyadenylation events on single mRNA molecules by full-length mRNA sequencing. RESULTS: In MCF-7 breast cancer cells, we find 2700 genes with interdependent alternative transcription initiation, splicing and polyadenylation events, both in proximal and distant parts of mRNA molecules, including examples of coupling between transcription start sites and polyadenylation sites. The analysis of three human primary tissues (brain, heart and liver) reveals similar patterns of interdependency between transcription initiation and mRNA processing events. We predict thousands of novel open reading frames from full-length mRNA sequences and obtained evidence for their translation by shotgun proteomics. The mapping database rescues 358 previously unassigned peptides and improves the assignment of others. By recognizing sample-specific amino-acid changes and novel splicing patterns, full-length mRNA sequencing improves proteogenomics analysis of MCF-7 cells. CONCLUSIONS: Our findings demonstrate that our understanding of transcriptome complexity is far from complete and provides a basis to reveal largely unresolved mechanisms that coordinate transcription initiation and mRNA processing. PMID- 29598824 TI - An integrated community health worker intervention in rural Nepal: a type 2 hybrid effectiveness-implementation study protocol. AB - BACKGROUND: Evidence-based medicines, technologies, and protocols exist to prevent many of the annual 300,000 maternal, 2.7 million neonatal, and 9 million child deaths, but they are not being effectively implemented and utilized in rural areas. Nepal, one of South Asia's poorest countries with over 80% of its population living in rural areas, exemplifies this challenge. Community health workers are an important cadre in low-income countries where human resources for health and health care infrastructure are limited. As local women, they are uniquely positioned to understand and successfully navigate barriers to health care access. Recent case studies of large community health worker programs have highlighted the importance of training, both initial and ongoing, and accountability through structured management, salaries, and ongoing monitoring and evaluation. A gap in the evidence regarding whether such community health worker systems can change health outcomes, as well as be sustainably adopted at scale, remains. In this study, we plan to evaluate a community health worker system delivering an evidence-based integrated reproductive, maternal, newborn, and child health intervention as it is scaled up in rural Nepal. METHODS: We will conduct a type 2 hybrid effectiveness-implementation study to test both the effect of an integrated reproductive, maternal, newborn, and child health intervention and the implementation process via a professional community health worker system. The intervention integrates five evidence-based approaches: (1) home-based antenatal care and post-natal care counseling and care coordination; (2) continuous surveillance of all reproductive age women, pregnancies, and children under age 2 years via a mobile application; (3) Community-Based Integrated Management of Newborn and Childhood Illness; (4) group antenatal and postnatal care; and 5) the Balanced Counseling Strategy to post-partum contraception. We will evaluate effectiveness using a pre-post quasi-experimental design with stepped implementation and implementation using the RE-AIM framework. DISCUSSION: This is the first hybrid effectiveness-implementation study of an integrated reproductive, maternal, newborn, and child health intervention in rural Nepal that we are aware of. As Nepal takes steps towards achieving the Sustainable Development Goals, the data from this three-year study will be useful in the detailed planning of a professionalized community health worker cadre delivering evidence-based reproductive, maternal, newborn, and child health interventions to the country's rural population. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03371186 , registered 04 December 2017, retrospectively registered. PMID- 29598825 TI - Combined flow cytometry and high-throughput image analysis for the study of essential genes in Caenorhabditis elegans. AB - BACKGROUND: Advances in automated image-based microscopy platforms coupled with high-throughput liquid workflows have facilitated the design of large-scale screens utilising multicellular model organisms such as Caenorhabditis elegans to identify genetic interactions, therapeutic drugs or disease modifiers. However, the analysis of essential genes has lagged behind because lethal or sterile mutations pose a bottleneck for high-throughput approaches, and a systematic way to analyse genetic interactions of essential genes in multicellular organisms has been lacking. RESULTS: In C. elegans, non-conditional lethal mutations can be maintained in heterozygosity using chromosome balancers, commonly expressing green fluorescent protein (GFP) in the pharynx. However, gene expression or function is typically monitored by the use of fluorescent reporters marked with the same fluorophore, presenting a challenge to sort worm populations of interest, particularly at early larval stages. Here, we develop a sorting strategy capable of selecting homozygous mutants carrying a GFP stress reporter from GFP-balanced animals at the second larval stage. Because sorting is not completely error-free, we develop an automated high-throughput image analysis protocol that identifies and discards animals carrying the chromosome balancer. We demonstrate the experimental usefulness of combining sorting of homozygous lethal mutants and automated image analysis in a functional genomic RNA interference (RNAi) screen for genes that genetically interact with mitochondrial prohibitin (PHB). Lack of PHB results in embryonic lethality, while homozygous PHB deletion mutants develop into sterile adults due to maternal contribution and strongly induce the mitochondrial unfolded protein response (UPRmt). In a chromosome-wide RNAi screen for C. elegans genes having human orthologues, we uncover both known and new PHB genetic interactors affecting the UPRmt and growth. CONCLUSIONS: The method presented here allows the study of balanced lethal mutations in a high-throughput manner. It can be easily adapted depending on the user's requirements and should serve as a useful resource for the C. elegans community for probing new biological aspects of essential nematode genes as well as the generation of more comprehensive genetic networks. PMID- 29598826 TI - The complexity of titin splicing pattern in human adult skeletal muscles. AB - BACKGROUND: Mutations in the titin gene (TTN) cause a large spectrum of diseases affecting skeletal and/or cardiac muscle. TTN includes 363 coding exons, a repeated region with a high degree of complexity, isoform-specific elements, and metatranscript-only exons thought to be expressed only during fetal development. Although three main classes of isoforms have been described so far, alternative splicing events (ASEs) in different tissues or in different developmental and physiological states have been reported. METHODS: To achieve a comprehensive view of titin ASEs in adult human skeletal muscles, we performed a RNA-Sequencing experiment on 42 human biopsies collected from 12 anatomically different skeletal muscles of 11 individuals without any skeletal-muscle disorders. RESULTS: We confirmed that the skeletal muscle N2A isoforms are highly prevalent, but we found an elevated number of alternative splicing events, some at a very high level. These include previously unknown exon skipping events and alternative 5' and 3' splice sites. Our data suggests the partial inclusion in the TTN transcript of some metatranscript-only exons and the partial exclusion of canonical N2A exons. CONCLUSIONS: This study provides an extensive picture of the complex TTN splicing pattern in human adult skeletal muscle, which is crucial for a proper clinical interpretation of TTN variants. PMID- 29598828 TI - The SAGA/TREX-2 subunit Sus1 binds widely to transcribed genes and affects mRNA turnover globally. AB - BACKGROUND: Eukaryotic transcription is regulated through two complexes, the general transcription factor IID (TFIID) and the coactivator Spt-Ada-Gcn5 acetyltransferase (SAGA). Recent findings confirm that both TFIID and SAGA contribute to the synthesis of nearly all transcripts and are recruited genome wide in yeast. However, how this broad recruitment confers selectivity under specific conditions remains an open question. RESULTS: Here we find that the SAGA/TREX-2 subunit Sus1 associates with upstream regulatory regions of many yeast genes and that heat shock drastically changes Sus1 binding. While Sus1 binding to TFIID-dominated genes is not affected by temperature, its recruitment to SAGA-dominated genes and RP genes is significantly disturbed under heat shock, with Sus1 relocated to environmental stress-responsive genes in these conditions. Moreover, in contrast to recent results showing that SAGA deubiquitinating enzyme Ubp8 is dispensable for RNA synthesis, genomic run-on experiments demonstrate that Sus1 contributes to synthesis and stability of a wide range of transcripts. CONCLUSIONS: Our study provides support for a model in which SAGA/TREX-2 factor Sus1 acts as a global transcriptional regulator in yeast but has differential activity at yeast genes as a function of their transcription rate or during stress conditions. PMID- 29598827 TI - Integrated biology approach reveals molecular and pathological interactions among Alzheimer's Abeta42, Tau, TREM2, and TYROBP in Drosophila models. AB - BACKGROUND: Cerebral amyloidosis, neuroinflammation, and tauopathy are key features of Alzheimer's disease (AD), but interactions among these features remain poorly understood. Our previous multiscale molecular network models of AD revealed TYROBP as a key driver of an immune- and microglia-specific network that was robustly associated with AD pathophysiology. Recent genetic studies of AD further identified pathogenic mutations in both TREM2 and TYROBP. METHODS: In this study, we systematically examined molecular and pathological interactions among Abeta, tau, TREM2, and TYROBP by integrating signatures from transgenic Drosophila models of AD and transcriptome-wide gene co-expression networks from two human AD cohorts. RESULTS: Glial expression of TREM2/TYROBP exacerbated tau mediated neurodegeneration and synergistically affected pathways underlying late onset AD pathology, while neuronal Abeta42 and glial TREM2/TYROBP synergistically altered expression of the genes in synaptic function and immune modules in AD. CONCLUSIONS: The comprehensive pathological and molecular data generated through this study strongly validate the causal role of TREM2/TYROBP in driving molecular networks in AD and AD-related phenotypes in flies. PMID- 29598829 TI - Depletion of DNMT1 in differentiated human cells highlights key classes of sensitive genes and an interplay with polycomb repression. AB - BACKGROUND: DNA methylation plays a vital role in the cell, but loss-of-function mutations of the maintenance methyltransferase DNMT1 in normal human cells are lethal, precluding target identification, and existing hypomorphic lines are tumour cells. We generated instead a hypomorphic series in normal hTERT immortalised fibroblasts using stably integrated short hairpin RNA. RESULTS: Approximately two-thirds of sites showed demethylation as expected, with one third showing hypermethylation, and targets were shared between the three independently derived lines. Enrichment analysis indicated significant losses at promoters and gene bodies with four gene classes most affected: (1) protocadherins, which are key to neural cell identity; (2) genes involved in fat homoeostasis/body mass determination; (3) olfactory receptors and (4) cancer/testis antigen (CTA) genes. Overall effects on transcription were relatively small in these fibroblasts, but CTA genes showed robust derepression. Comparison with siRNA-treated cells indicated that shRNA lines show substantial remethylation over time. Regions showing persistent hypomethylation in the shRNA lines were associated with polycomb repression and were derepressed on addition of an EZH2 inhibitor. Persistent hypermethylation in shRNA lines was, in contrast, associated with poised promoters. CONCLUSIONS: We have assessed for the first time the effects of chronic depletion of DNMT1 in an untransformed, differentiated human cell type. Our results suggest polycomb marking blocks remethylation and indicate the sensitivity of key neural, adipose and cancer associated genes to loss of maintenance methylation activity. PMID- 29598830 TI - The putative amino acid ABC transporter substrate-binding protein AapJ2 is necessary for Brucella virulence at the early stage of infection in a mouse model. AB - Brucellosis is a zoonotic bacterial disease caused by Brucella spp. The virulence of these bacteria is dependent on their ability to invade and replicate within host cells. In a previous study, a putative gene bab_RS27735 encoding an amino acid ABC transporter substrate-binding protein homologous to AapJ protein was found to be involved in Brucella abortus virulence. In this study, we successfully constructed a bab_RS27735 deletion mutant, Delta27735. Compared with the wild-type strain, the lipopolysaccharide pattern of the mutant was not changed, but the growth ability was slightly defected in the exponential phase. In tolerance tests, sensitivity of the Delta27735 mutant to oxidative stress, bactericidal peptides or low pH was not different from that of the wild-type strain. Cell infection assay showed that the mutant was reduced survival within macrophages but could efficiently escape lysosome degradation. The results of a virulence test showed that the Delta27735 mutant was attenuated in a mouse model at the early stage of infection but recovered its virulence at the late stage of infection. Meanwhile, the development of splenomegaly and histopathological lesions was observed in mice infected with either the wild-type strain or the mutant. These results are in line with the release of IL-12p40 and TNF-alpha into the peripheral blood of infected mice. Besides, expression of diverse genes was up-regulated in the Delta27735 mutant, which may contribute to the reduced virulence of the mutant. These data elucidated that the bab_RS27735 gene is necessary for B. abortus virulence at the early stage of infection in a mouse model. PMID- 29598832 TI - Guideline on cochlear implants. AB - INTRODUCTION: In the last decade numerous hospitals have started to work with patients who are candidates for a cochlear implant (CI) and there have been numerous and relevant advances in the treatment of sensorineural hearing loss that extended the indications for cochlear implants. OBJECTIVES: To provide a guideline on cochlear implants to specialists in otorhinolaryngology, other medical specialities, health authorities and society in general. METHODS: The Scientific Committees of Otology, Otoneurology and Audiology from the Spanish Society of Otolaryngology and Head and Neck Surgery (SEORL-CCC), in a coordinated and agreed way, performed a review of the current state of CI based on the existing regulations and in the scientific publications referenced in the bibliography of the document drafted. RESULTS: The clinical guideline on cochlear implants provides information on: a) Definition and description of Cochlear Implant; b) Indications for cochlear implants; c) Organizational requirements for a cochlear implant programme. CONCLUSIONS: A clinical guideline on cochlear implants has been developed by a Committee of Experts of the SEORL-CCC, to help and guide all the health professionals involved in this field of CI in decision making to treathearing impairment.

AB - Prognostic models are powerful tools for treatment personalisation. However, not all proposed models work well when validated using new data, despite impressive results being reported initially. Here, we will use a hands-on approach to highlight important aspects of prognostic modelling, as well as to demonstrate methods to generate generalisable models.

AB - Autoimmune disease management presents a significant challenge to medical science. Environmental factors potentially increase the risk of developing inflammatory and autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and lupus. Among various environmental stresses, cigarette smoke and hypoxia have both been reported to lead to an enhanced risk of inflammatory and autoimmune diseases.In this review, we shed light on all reported mechanisms whereby cigarette smoke and a hypoxic environment can induce inflammatory and autoimmune diseases and discuss how hypoxic conditions influence the cigarette smoke-induced threat of inflammatory and autoimmune disease development.Cigarette smoke and hypoxia both lead to increased oxidative stress and production of reactive oxygen species and other free radicals, which have various effects including the generation of autoreactive pro-inflammatory T cells and autoantibodies, reductions in T regulatory (Treg) cell activity, and enhanced expression of pro-inflammatory mediators [e.g., interleukin-6 (IL-6), interleukin 4 (IL-4) and interleukin-8 (IL-8)]. Accordingly, smoking and hypoxic environments may synergistically act as potent environmental risk factors for inflammatory and autoimmune diseases. To our knowledge, no studies have reported the direct association of cigarette smoke and hypoxic environments with the risk of developing inflammatory and autoimmune diseases.Future studies exploring the risk of autoimmune disease development in smokers at high altitudes, particularly military personnel and mountaineers who are not acclimatized to high-altitude regions, are required to obtain a better understanding of disease risk as well as its management. PMID- 29598836 TI - Effects of personality functioning on the global functioning of patients with bipolar disorder I. AB - Due to the comorbidity of personality traits or disorders and BD, the present study investigated the extent to which the global functioning of patients with BD would be affected by personality functioning. This study included 100 subsequent patients who had been diagnosed with BD-I, and were in the remission phase. Global functioning was assessed with the Bipolar Disorder Functioning Questionnaire (BDFQ) and the Level of Personality Functioning Scale (LPFS) was conducted following psychodynamic-oriented semi-structured interviews to assess the level of personality functioning. Hierarchical linear regression models were conducted. After controlling other variables, the predictability of LPFS components on global functionality was assessed. Global functioning was negatively correlated with subsyndromal depressive symptoms, the presence of a psychiatric comorbidity, alcohol/substance use disorders, the side effects of medication, poor social support, and an impaired level of personality functioning. Finally, a decrease in the level of personality functioning predicted impaired global functioning. The present study demonstrated that the level of personality functioning had a significant impact on global functioning during the euthymic period of BD. Therefore, the assessment of the level of personality functioning in patients with BD will aid in better understanding this population and in the design of long-term treatment plans. PMID- 29598834 TI - Clinical outcome after high-precision radiotherapy for skull base meningiomas: Pooled data from three large German centers for radiation oncology. AB - PURPOSE: To evaluate outcome in patients with base of skull meningiomas treated with modern high precision radiation therapy (RT) techniques. PATIENTS AND METHODS: 927 patients from three centers were treated with either radiosurgery or fractionated high-precision RT for meningiomas. Treatment planning was based on CT and MRI following institutional guidelines. For radiosurgery, a median dose of 13 Gy was applied, for fractionated treatments, a median dose of 54 Gy in 1.8 Gy single fractions was prescribed. Follow-up included a clinical examination as well as contrast-enhanced imaging. All patients were followed up prospectively after radiotherapy in the three departments within a strict follow-up regimen. The median follow-up time was 81 months (range 1-348 months). RESULTS: Median local control was 79 months (range 1-348 months). Local control (LC) was 98% at 1 year, 94% at 3 years, 92% at 5 years and 86% at 10 years. There was no difference between radiosurgery and fractionated RT. We analyzed the influence of higher doses on LC and could show that dose did not impact LC. Moreover, there was no difference between 54 Gy and 57.6 Gy in the fractionated group. Side effects were below 5% in both groups without any severe treatment-related complications. DISCUSSION: Based on the pooled data analysis this manuscript provides a large series of meningiomas of the skull base treated with modern high precision RT demonstrating excellent local control and low rates of side effects. Such data support the recommendation of RT for skull base meningiomas in the interdisciplinary tumor board discussions. The strong role of RT must influence treatment recommendations keeping in mind the individual risk-benefit profile of treatment alternatives. PMID- 29598837 TI - Effects of cochlear synaptopathy on middle-ear muscle reflexes in unanesthetized mice. AB - Cochlear synaptopathy, i.e. the loss of auditory-nerve connections with cochlear hair cells, is seen in aging, noise damage, and other types of acquired sensorineural hearing loss. Because the subset of auditory-nerve fibers with high thresholds and low spontaneous rates (SRs) is disproportionately affected, audiometric thresholds are relatively insensitive to this primary neural degeneration. Although suprathreshold amplitudes of wave I of the auditory brainstem response (ABR) are attenuated in synaptopathic mice, there is not yet a robust diagnostic in humans. The middle-ear muscle reflex (MEMR) might be a sensitive metric (Valero et al., 2016), because low-SR fibers may be important drivers of the MEMR (Liberman and Kiang, 1984; Kobler et al., 1992). Here, to test the hypothesis that narrowband reflex elicitors can identify synaptopathic cochlear regions, we measured reflex growth functions in unanesthetized mice with varying degrees of noise-induced synaptopathy and in unexposed controls. To separate effects of the MEMR from those of the medial olivocochlear reflex, the other sound-evoked cochlear feedback loop, we used a mutant mouse strain with deletion of the acetylcholine receptor required for olivocochlear function. We demonstrate that the MEMR is normal when activated from non-synaptopathic cochlear regions, is greatly weakened in synaptopathic regions, and is a more sensitive indicator of moderate synaptopathy than the suprathreshold amplitude of ABR wave I. PMID- 29598838 TI - Hidden hearing loss and endbulbs of Held: Evidence for central pathology before detection of ABR threshold increases. AB - Reductions in sound-evoked activity in the auditory nerve due to hearing loss have been shown to cause pathological changes in central auditory structures. Hearing loss due strictly to the aging process are less well documented. In this study of CBA/CaH mice, we provide evidence for age-related pathology in the endbulb of Held, a large axosomatic ending arising from myelinated auditory nerve fibers. Endbulbs are known to be involved in the processing of temporal cues used for sound localization and speech comprehension. Hearing thresholds as measured by auditory brainstem response (ABR) thresholds remained stable up to one year, whereas suprathreshold amplitudes of early ABR waves decreased by up to 50% in older mice, similar to that reported for age-related cochlear synaptopathy (Sergeyenko et al., 2013). The reduction of ABR response magnitude with age correlated closely in time with the gradual atrophy of endbulbs of Held, and is consistent with the hypothesis that endbulb integrity is dependent upon normal levels of spike activity in the auditory nerve. These results indicate that central auditory pathologies emerge as consequence of so-called "hidden" hearing loss and suggest that such brain changes require consideration when devising therapeutic interventions. PMID- 29598839 TI - Auditory and audio-vocal responses of single neurons in the monkey ventral premotor cortex. AB - Monkey vocalization is a complex behavioral pattern, which is flexibly used in audio-vocal communication. A recently proposed dual neural network model suggests that cognitive control might be involved in this behavior, originating from a frontal cortical network in the prefrontal cortex and mediated via projections from the rostral portion of the ventral premotor cortex (PMvr) and motor cortex to the primary vocal motor network in the brainstem. For the rapid adjustment of vocal output to external acoustic events, strong interconnections between vocal motor and auditory sites are needed, which are present at cortical and subcortical levels. However, the role of the PMvr in audio-vocal integration processes remains unclear. In the present study, single neurons in the PMvr were recorded in rhesus monkeys (Macaca mulatta) while volitionally producing vocalizations in a visual detection task or passively listening to monkey vocalizations. Ten percent of randomly selected neurons in the PMvr modulated their discharge rate in response to acoustic stimulation with species-specific calls. More than four-fifths of these auditory neurons showed an additional modulation of their discharge rates either before and/or during the monkeys' motor production of the vocalization. Based on these audio-vocal interactions, the PMvr might be well positioned to mediate higher order auditory processing with cognitive control of the vocal motor output to the primary vocal motor network. Such audio-vocal integration processes in the premotor cortex might constitute a precursor for the evolution of complex learned audio-vocal integration systems, ultimately giving rise to human speech. PMID- 29598840 TI - Emergency Tracheal Intubation in an Ankylosing Spondylitis Patient in a Sitting Position Using an Airway Scope Combined with Face-to-Face and Digital Intubation. AB - BACKGROUND: Emergency intubation in a patient with advanced ankylosing spondylitis (AS) who presents with severe thoracic kyphosis deformity, rigid cervical flexion deformity of the neck, and an inability to achieve the supine position is particularly challenging to emergency physicians. CASE REPORT: This study reports on an AS patient presenting with these difficult airway characteristics and acute respiratory failure who was successfully intubated using video laryngoscope-assisted inverse intubation (II) and blind digital intubation (BDI). By using Pentax AirwayScope-assisted inverse intubation, the tracheal tube tip was passed through the glottic opening, but an unexpected resistance occurred during tube advancement, which was overcome by subsequent BDI. By using laryngoscope-assisted II complemented by the BDI technique, the patient was successfully intubated without complications. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Our case demonstrated that these two emergency airway management techniques are valuable backup methods and complement each other when applied to certain unstable airways, especially when the traditional patient position is not easily accomplished. Unexpected difficulty is not rare during airway management; emergency physicians should always be well prepared both mentally and practically. PMID- 29598841 TI - Narrow width of muscle-preserving selective laminectomy demonstrated sufficient surgical outcomes and reduced surgical invasiveness. AB - Sufficient width of laminectomy or laminoplasty is considered a criterion for successful surgical outcomes following posterior cervical decompression. No previous study has focused on surgical outcomes achieved by wide versus narrow decompression. This study examined whether narrow laminectomy width (LW) affected surgical outcomes in cervical compressive myelopathy (CCM). Between 2005 and 2010, we performed muscle-preserving selective laminectomy (SL) with decompression between the bilateral medial margin of the facet joints (wide SL). After 2010, we began to perform narrow SL, in which the LW was no more than 2-3 mm wider than the spinal cord width (SW). Clinical features and radiological findings from 97 CCM patients in whom SL was performed at two consecutive levels, including the C4/5 level, were examined in this study. The relationship between LW and patients' functional outcomes was analyzed. Mean blood loss was lower in the narrow SL group than in the wide SL group. The length of hospital stay was also shorter in the narrow SL group. The wide SL group showed greater posterior spinal cord shift. The incidence of C5 palsy correlated with LW and LW minus SW (LW-SW). The recovery rate (RR) of Japanese Orthopaedic Association score was comparable between the two groups. The RR was not correlated with LW and LW-SW. Sufficient functional recovery can be achieved by narrow SL, and it offers advantages over wide posterior decompression, including reduced surgical invasiveness and complications. Wide decompression width is not always necessary for CCM patients. PMID- 29598842 TI - Comparison of tramadol/acetaminophen fixed-dose combination, tramadol, and acetaminophen in patients undergoing ambulatory arthroscopic meniscectomy. AB - OBJECTIVES: Preemptive analgesia is a technique in which analgesics are administered before a surgery to provide better postoperative pain relief with fewer side effects. In this study, we aimed to compare the preemptive efficacy of tramadol/acetaminophen fixed-dose combination, tramadol, and acetaminophen in patients undergoing ambulatory arthroscopic partial meniscectomy. METHODS: We evaluated the patient records of 75 patients who underwent ambulatory arthroscopic partial meniscectomy. We divided the patients into three groups consisting of 20 patients each to equalize the groups. Group A comprised patients who were administered 37.5 mg tramadol/325 mg acetaminophen fixed-dose combination, Group B comprised patients who were administered 50 mg tramadol, and Group C comprised patients who were administered 500 mg acetaminophen. Premedication was not used in any group. RESULTS: There were no significant differences between the groups in terms of age, sex, BMI, and duration of surgery and anesthesia. All patients in Group B and Group C and 17 patients in Group A required rescue analgesics in the first 6 h. Visual analog scale (VAS) was 4.75 +/- 3.05 in Group B at time 0 and was 6.10 +/- 1.86 in Group C in the first hour and was higher than the other groups with a statistically significance (p = 0.030 and 0.020, respectively). VAS at 24 h postoperatively was <=3 (1.60 +/- 1.63, 1.55 +/- 1.84 and 1.70 +/- 0.65 respectively in each group), and none of the patients in any group required rescue analgesics. No major side effects, except for slight nausea in one patient requiring no medication, were noted in any group. CONCLUSION: The fixed-dose combination of tramadol/acetaminophen or tramadol alone is better than acetaminophen alone as a preemptive analgesic in patients undergoing ambulatory arthroscopic meniscectomy. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID- 29598843 TI - Treatment outcome of dome osteotomy of the pelvis combined with trochanteric advancement for sequelae of Perthes' disease. AB - OBJECTIVE: Disparity in size between femoral head and acetabulum could promote premature degeneration of the hip joint. The purpose of this study was to report the results of Kawamura's dome osteotomy for acetabular dysplasia due to sequelae of Perthes' disease. PATIENTS AND METHODS: Fourteen patients (14 hips) operated between 1999 and 2012 were retrospectively reviewed. There were 9 males and 5 females with a mean age of 29 years (range, 15-54 years). Functional and radiological results were reviewed at mean follow-up of 9 years (range, 4-12 years). RESULTS: Pain relief was obtained in 13 of 14 (92.8%) patients postoperatively. Good to excellent functional outcome was obtained in 10 of 14 (71.4%) patients. Mean Harris hip score was improved from 63 to 84 (p < 0.05) at the final follow-up. Improvement of limping gait was observed in 10 of 14 (71.4%) patients. Center edge angle improved from mean 24 degrees (11-36 degrees ) preoperatively to mean 35 degrees (27-46 degrees ) postoperatively (p < 0.05), acetabular angle improved from mean 43 degrees (36-49 degrees ) preoperatively to mean 37 degrees (32-44 degrees ) postoperatively (p < 0.05), acetabular head index improved from mean 69% (50-83%) preoperatively to mean 85% (73-100%) postoperatively (p < 0.05). Progression of arthrosis stage occurred in 3 of 14 (21%) patients. None of the hip with preoperative Stulberg III, 2 of 9 hips with Stulberg IV and 2 of 2 hips with Stulberg V needed conversion to total hip arthroplasty during the follow-up. CONCLUSION: Dome osteotomy of the pelvis combined with trochanteric advancement could give a reasonable treatment outcome for acetabular dysplasia due to Perthes' disease at mid to long-term follow-up. Advanced stage of arthrosis, preoperative Stulberg V and no improvement of limping gait after the surgery possibly associated with poor outcome. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID- 29598844 TI - Effect of BMI on outcomes of surgical treatment for tibial plateau fractures: A comparative retrospective case series study. AB - PURPOSE: Tibia plateau fracture (TPF) treatment aims at achieving a stable, aligned, mobile, painless knee and preventing post-traumatic osteoarthritis. To achieve this goal, surgeons consider criteria such as patients' characteristics, severity, risk of complications, fracture displacement/depression, degree of soft tissue injury. However, body mass index (BMI) is not considered as a risk factor in literature. Our study was conducted to find out any possible correlation between BMI and functional scores or radiological score separately. METHODS: Retrospective analysis of case series between 2011 and 2014 was done on the database of a tertiary hospital in Istanbul. There were 67 TPF patients (54 males, 13 females) in the study. Relationship between BMI and functional knee scores or radiological score was compared statistically. Closed fractures with both high-energy and low-energy injury were included in the study. Patients with open fracture, multi-trauma presence, meniscus and/or ligamentous injury, increased co-morbidity, inadequate records (25 cases in all) were excluded. Surgery type, Schatzker classification, injury side, trauma energy, and gender were considered as possible risk factors. Binary regression analysis was done for possible factors affecting functional knee scores and radiologic score. RESULTS: Model summary calculations were done as Nagelkerke R2 test for Knee Society score, Lysholm knee score, and Ahlback and Rydberg radiologic scores, which were 0.648, 0.831, and 0.327 respectively. Homer-Lemeshow test values were 0.976, 0.998, and 0.362, respectively. There is negative correlation between BMI and both knee function scores. There is no correlation between BMI and radiologic score. CONCLUSION: An increase in BMI has a negative effect on functional knee scores after surgical treatment of TPFs. Therefore, BMI should be considered as a risk factor for surgical treatment of TPFs. PMID- 29598845 TI - Urinary parabens and triclosan concentrations and associated exposure characteristics in a Korean population-A comparison between night-time and first morning urine. AB - Parabens and triclosan have been widely used in many personal care products and cosmetics. The endocrine disrupting potential of these compounds is of increasing public health concern. The aim of this study is to understand the current exposure profile of these chemicals in last void before bedtime (night-time) and first-morning void (first-morning) urines among a Korean population and to characterize their exposure sources and pathways. A total of 261 people, including infants (0-2 years), toddlers (3-6 years), children (7-12 years), adolescents (13-18 years), and adults (>=19 years), were recruited, and sampled for night-time urine and first-morning urine of the following day. Methyl (MeP), ethyl (EtP), propyl (PrP) and butyl paraben (BuP), and triclosan were measured in urine. The demographic characteristics, use of personal care products, and food consumption were obtained through a questionnaire. Among the target compounds, EtP and MeP were most frequently detected at the highest concentrations. The median concentration of EtP in night-time urine was 32.4 MUg/L (interquartile range: 8.37-82.8 MUg/L), which is higher than previously reported worldwide. Unlike other test compounds, compared to those measured from first-morning urine, the EtP concentrations were significantly higher in night-time urine, suggesting the presence of different exposure sources. Among adults, the MeP and PrP concentrations in night-time urine were associated with frequent use of skin care products, colored cosmetics, bath products, toothpaste, vinyl food packaging, or consumption of canned food. The MeP and PrP concentrations were higher in females than in males, especially in night-time urine. The results of this study also show that multiple urine samples are necessary to capture the diurnal variation of non-occupational exposure to environmental chemicals, such as parabens. PMID- 29598846 TI - The role of mitochondrial activity in female fertility and assisted reproductive technologies: overview and current insights. AB - Mitochondria have been implicated as key factors regulating female reproductive processes. Notable progress has been made in determining the role of mitochondria with respect to oocyte maturation, fertilization and early embryo development. In addition, mitochondrial function and dysfunction has been the subject of various studies in ovarian ageing and metabolic stress models. However, the overall mitochondrial impact on female fertility is yet to be uncovered. The mitochondrial DNA content of granulosa, cumulus and trophectoderm cells is being explored as a biomarker of oocyte quality and embryo viability. As growing evidence suggests that embryo potential could be related to the ability of oocyte mitochondria to generate energy, efforts have been made to investigate the possibility of improving mitochondrial capacity in women with poor outcomes after treatment with assistedreproductive technologies. Thus far, therapeutic attempts have focused mainly on using nutrients to restore mitochondrial function and transferring mitochondria from autologous germline precursor cells. Moreover, new perspectives on optimizing infertility treatments have arisen with modern mitochondrial replacement therapies, which are being applied in women with mitochondrial disease-causing mutations. This review explores aspects of the distinctive contribution of mitochondria to reproductive processes and discusses current and emerging clinical implications.

PMID- 29598850 TI - Evaluation of risk factors for complications after bariatric surgery. AB - The decision to perform a bariatric surgical procedure, the conclusion of a clinical pathway in which management is individually adapted to each patient, is taken after multidisciplinary consultation. Paradoxically, the patients who would most benefit from surgery are also those who have the highest operative risk. In practice, predictive factors of mortality and severe postoperative complications (Clavien-Dindo>III) must be used to evaluate the benefit/risk ratio most objectively. The main risk factors are age, male gender, body mass index, obstructive sleep apnea syndrome, insulin resistance and diabetes, tobacco abuse, cardiovascular disease, ability to lose weight before surgery, hypoalbuminemia and functional disability. Routine preoperative evaluation of high perioperative risk patients provides the attending physician with information to: (1) correct several of these risk factors before surgery and thereby limit the operative risk; (2) orient the patient to a less risky surgical procedure and/or to a facility with a more adapted technical capacity, as necessary; (3) contra indicate the operation if the risks exceed the expected benefits. All in all, this preoperative evaluation combined with management of comorbidities contributes to decrease the risk of postoperative complications and to improve the overall management of obese patients. PMID- 29598851 TI - First Magnetic Resonance Managed by a Cardiology Department in the Spanish Public Healthcare System. Experience and Difficulties of an Innovative Model. AB - Magnetic resonance (MR) is considered the gold standard in the assessment of myocardial morphology, function, perfusion, and viability. However, its main limitation is its scarce availability. In 2014, we installed the first MR scanner exclusively managed by a cardiology department within the publicly-funded Spanish healthcare system with the aim of improving patient-care, training and research in the department. In the time interval analyzed, July 2014 to May 2017, 3422 cardiac MR scans were performed (32minutes used per study; 96% with good quality; 75% with contrast media administration). The most prevalent clinical indications were cardiomyopathy (29%) and ischemic heart disease (12%). Twenty-five percent of studies were conducted in the context of research protocols. Follow-up studies predominated among outpatients, while pretherapeutic assessment was more common in hospitalized patients. The presumptive diagnosis was changed by cardiac MR scanning in up to 20% of patients investigated for ischemic heart disease. The installation and operative management of an MR scanner in our cardiology department has allowed us to integrate this technique into daily clinical practice, modify our clinical protocols, optimize access to this technology among cardiac patients, improve training, and conduct clinical research. PMID- 29598853 TI - Simultaneous influence of indigenous microorganism along with abiotic factors controlling arsenic mobilization in Brahmaputra floodplain, India. AB - In the dynamic cycling of oxic and anoxic aqueous alluvial aquifer environments, varying Arsenic (As) concentrations are controlled by both abiotic and biotic factors. Studies have shown a significant form of toxic As (III) being released through the reductive dissolution of iron-oxy/hydroxide minerals and microbial reduction mechanisms, which leads to a serious health concern. The present study was performed in order to assess the abiotic and biotic factors influencing As release into the alluvial aquifer groundwater in Brahmaputra floodplain, India. The groundwater chemistry, characterization of the sediments, isolation, identification and characterization of prominent As releasing indigenous bacterium were conducted. The measured solid and liquid phases of total As concentration were ranged between 0.02 and 17.2 mg kg-1 and 8 to 353 MUg L-1, respectively. The morphology and mineralogy showed the presence of detrital and authigenic mineral assemblages whereas primary and secondary As bearing Realgar and Claudetite minerals were identified, respectively. Furthermore, significant non-labile As fraction was found associated with the amorphous oxides of Fe, Mn and Al. The observed groundwater chemistry and sediment color, deduced a sub-oxic reducing aquifer conditions in As-contaminated regions. In addition, 16S rDNA sequencing results of the isolated bacterium showed the prominent Pseudomonas aeruginosa responsible for the mobilization of As, reducing condition, biomineralization and causing grey color to the sediments at the shallower and deeper aquifers in the study area. These findings suggest that microbial metabolic activities are equally responsible in iron-oxy/hydroxide reductive dissolution, controlling As mobilization in dynamic fluvial flood plains. PMID- 29598854 TI - Utility of Invasive Electrophysiology Studies in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation. AB - Permanent pacemaker (PPM) implantation remains common after transcatheter aortic valve implantation (TAVI). Invasive electrophysiology studies (EPSs) may reduce PPM implantation rates by identifying patients who do not require long-term pacing. At our institution, a new strategy in which patients with equivocal indications for pacing underwent EPSs to determine the need for PPM implantation was adopted. We compared baseline demographics, TAVI procedural details, and outcomes in patients without any conduction disturbance after TAVI, patients with new PPM implantation, and patients with EPS +/- new PPM implantation. After exclusion for preexisting PPMs, of a total of 614 consecutive TAVI patients, 117 (19.1%) required new PPM implantation for unequivocal pacing indications, and 95 (15.5%) underwent EPSs. Of those patients who underwent EPSs, 28 (29.5%) required PPM implantation and 67 (70.5%) did not. The overall rate of new PPM implantation was higher for self-expanding versus balloon-expandable valves (34.0% vs 19.9%, p = 0.0011). PPM implantation increased intensive care and hospital length of stay compared with patients without any conduction disturbance (10.7 +/- 8.3 vs 8.5 +/ 6.4 days, p = 0.003). A negative EPS did not prolong length of stay. There were no significant differences in 30-day and 1-year mortality between groups. In conclusion, among TAVI patients with new-onset conduction disturbance, EPS is a safe strategy to identify those who require PPM implantation and those in whom PPMs can be avoided. PMID- 29598855 TI - Role of Percutaneous Coronary Intervention in the Treatment of Cardiac Allograft Vasculopathy. AB - We evaluated our quarter-century experience with percutaneous coronary intervention (PCI) in patients with cardiac allograft vasculopathy (CAV). CAV is a progressive form of atherosclerosis that is characterized by diffuse intimal thickening. It is a major cause of morbidity and mortality after orthotopic heart transplantation (OHT). Effective treatment options are limited. PCI has been used as a palliative treatment in selected patients. We retrospectively analyzed 140 patients with CAV who underwent PCI from 1992 to 2017 at the University of California, Los Angeles (UCLA) Medical Center. The primary end point was freedom from death, myocardial infarction (MI), target vessel revascularization (TVR), and repeat OHT, at a follow-up of 10 years. PCI was unsuccessful in 3 patients (2%). Balloon angioplasty (n = 7), bare metal stents (n = 50), or drug-eluting stents (DES, n = 80) were used for PCI. Freedom from the primary end point was 17 +/- 8%. The use of DES did not provide significant benefit for the primary end point (23 +/- 14% vs 10 +/- 9%, p = 0.16). Freedom from the individual end points was low: death was 43 +/- 10%, MI was 74 +/- 12%, TVR was 54 +/- 12%, and repeat OHT was 42 +/- 15%. Freedom from TVR was not significantly different from DES and bare metal stent (67 +/- 14% vs 52 +/- 20%, p = 0.46). In conclusion, among patients who underwent PCI for CAV, freedom from the composite of death, MI, TVR, and repeat OHT was low.

This is the first Canadian series on Lyme carditis manifested as high-degree atrioventricular block. We report 5 recent cases presented over a 2-year period. The variation of nonspecific presentations requires a high index of suspicion for prompt diagnosis and correct management. Recognizing this early would curtail the progression of conduction disorders and potentially avoid permanent pacemaker implantation. PMID- 29598857 TI - The Impact of U.S. Free Trade Agreements on Calorie Availability and Obesity: A Natural Experiment in Canada. AB - INTRODUCTION: Globalization via free trade and investment agreements is often implicated in the obesity pandemic. Concerns center on how free trade and investment agreements increase population exposure to unhealthy, high-calorie diets, but existing studies preclude causal conclusions. Few studies of free trade and investment agreements and diets isolated their impact from confounding changes, and none examined any effect on caloric intake, despite its critical role in the etiology of obesity. This study addresses these limitations by analyzing a unique natural experiment arising from the exceptional circumstances surrounding the implementation of the 1989 Canada-U.S. Free Trade Agreement. METHODS: Data from the UN (2017) were analyzed using fixed-effects regression models and the synthetic control method to estimate the impact of the Canada-U.S. Free Trade Agreement on calorie availability in Canada, 1978-2006, and coinciding increases in U.S. exports and investment in Canada's food and beverage sector. The impact of changes to calorie availability on body weights was then modeled. RESULTS: Calorie availability increased by ?170 kilocalories per capita per day in Canada after the Canada-U.S. Free Trade Agreement. There was a coinciding rise in U.S. trade and investment in the Canadian food and beverage sector. This rise in calorie availability is estimated to account for an average weight gain of between 1.8 kg and 12.2 kg in the Canadian population, depending on sex and physical activity levels. CONCLUSIONS: The Canada-U.S. Free Trade Agreement was associated with a substantial rise in calorie availability in Canada. U.S. free trade and investment agreements can contribute to rising obesity and related diseases by pushing up caloric intake. PMID- 29598858 TI - Factors Associated With County-Level Differences in U.S. Drug-Related Mortality Rates. AB - INTRODUCTION: Over the past 2 decades, drug-related deaths have grown to be a major U.S. public health problem. County-level differences in drug-related mortality rates are large. The relative contributions of social determinants of health to this variation, including the economic, social, and healthcare environments, are unknown. METHODS: Using data from the U.S. Centers for Disease Control and Prevention Multiple-Cause of Death Files (2006-2015, analyzed in 2017); U.S. Census Bureau; U.S. Department of Agriculture Economic Research Service; Agency for Healthcare Research and Quality; and Northeast Regional Center for Rural Development, this paper modeled associations between county level drug-related mortality rates and economic, social, and healthcare environments. Spatial autoregressive models controlled for state fixed effects and county demographic characteristics. RESULTS: The average county-level age adjusted drug-related mortality rate was 16.6 deaths per 100,000 population (2006 2015), but there were substantial geographic disparities in rates. Controlling for county demographic characteristics, average mortality rates were significantly higher in counties with greater economic and family distress and in counties economically dependent on mining. Average mortality rates were significantly lower in counties with a larger presence of religious establishments, a greater percentage of recent in-migrants, and counties with economies reliant on public (government) sector employment. Healthcare supply factors did not contribute to between-county disparities in mortality rates. CONCLUSIONS: Drug-related mortality rates are not randomly distributed across the U.S. Future research should consider the specific pathways through which economic, social, and healthcare environments are associated with drug-related mortality. PMID- 29598859 TI - Long-Term Outcomes Following Surgical Aortic Bioprosthesis Implantation. AB - BACKGROUND: Few data exist on long-term outcomes and structural valve degeneration (SVD) in consecutive unselected patients undergoing surgical aortic valve replacement (SAVR). OBJECTIVES: The goal of this study was to determine the long-term outcomes of a contemporary cohort of consecutive unselected SAVR recipients with a focus on evaluating clinical outcomes and SVD based on echocardiographic criteria. METHODS: A total of 672 consecutive patients (mean age: 72 +/- 8 years; 61.5% male) undergoing SAVR with a bioprosthesis between 2002 and 2004 were included. Baseline and follow-up data were prospectively collected in a dedicated database. Baseline post-operative echocardiographic data were obtained in the 624 patients alive at hospital discharge and in 209 patients at 10 years (87% of the patients at risk). SVD was defined as subclinical (increase >10 mm Hg in mean transvalvular gradient + decrease >0.3 cm2 in valve area and/or new-onset mild or moderate aortic regurgitation) and clinically relevant (increase >20 mm Hg in mean transvalvular gradient + decrease >0.6 cm2 in valve area and/or new-onset moderate-to-severe aortic regurgitation). RESULTS: At a median follow-up of 10 years (interquartile range: 5 to 13 years), 432 patients (64.3%) had died. Older age, left ventricular dysfunction, atrial fibrillation, chronic obstructive pulmonary disease, greater body mass index, and diabetes mellitus were associated with an increased mortality risk (p < 0.05 for all). Clinically relevant SVD occurred in 6.6% of patients; 30.1% of patients had subclinical SVD. A greater body mass index and the use of a specific aortic bioprosthesis were independently associated with clinically relevant SVD (p < 0.05 for both), and 83% of these patients underwent aortic valve reintervention (valve-in-valve transcatheter aortic valve replacement in 44% of them). CONCLUSIONS: The 10-year mortality rate in elderly SAVR recipients of a bioprosthetic valve was considerable, chiefly determined by their older age and the presence of comorbidities. Clinically relevant SVD was infrequent, but close to one third of the population exhibited subclinical SVD. These results provide contemporary data on long-term clinical outcomes and SVD post-SAVR, and they should be taken into consideration when evaluating late clinical outcomes and valve durability after transcatheter aortic valve replacement.

PMID- 29598861 TI - Rapid Deployment Versus Conventional Bioprosthetic Valve Replacement for Aortic Stenosis. AB - BACKGROUND: Surgical aortic valve replacement using conventional biological valves (CBVs) is the standard of care for treatment of old patients with aortic valve disease. Recently, rapid deployment valves (RDVs) have been introduced. OBJECTIVES: The purpose of this study was to report the nationwide German experience concerning RDVs for treatment of aortic valve stenosis and provide a head-to-head comparison with CBVs. METHODS: A total of 22,062 patients who underwent isolated surgical aortic valve replacement using CBV or RDV between 2011 and 2015 were enrolled into the German Aortic Valve Registry. Baseline, procedural, and in-hospital outcome parameters were analyzed for CBVs and RDVs using 1:1 propensity score matching. Furthermore, 3 RDVs were compared with each other. RESULTS: A total of 20,937 patients received a CBV, whereas 1,125 patients were treated with an RDV. Patients treated with an RDV presented with significantly reduced procedure (160 min [25th to 75th percentile: 135 to 195 min] vs. 150 min [25th to 75th percentile: 127 to 179 min]; p < 0.001), cardiopulmonary bypass (83 min [25th to 75th percentile: 68 to 104 min] vs. 70 min [25th to 75th percentile: 56 to 87 min]; p < 0.001), and aortic cross clamp times (60 min [25th to 75th percentile: 48 to 75 min] vs. 44 min [25th to 75th percentile: 35 to 57 min]; p < 0.001), but showed significantly elevated rates of pacemaker implantation (3.7% vs. 8.8%; p < 0.001) and disabling stroke (0.9% vs. 2.2%; p < 0.001), whereas in-hospital mortality was similar (1.7% vs. 2.2%; p = 0.22). These findings persisted after 1:1 propensity score matching. Comparison of the 3 RDVs revealed statistically nonsignificant different pacemaker rates and significantly different post-operative transvalvular gradients. CONCLUSIONS: In this large, all-comers database, the incidence of pacemaker implantation and disabling stroke was higher with RDVs, whereas no beneficial effect on in hospital mortality was seen. The 3 RDVs presented different complication profiles with regard to pacemaker implantation and transvalvular gradients. (German Aortic Valve Registry [GARY]; NCT01165827).

PMID- 29598863 TI - Presenting Systolic Blood Pressure and Outcomes in Patients With Acute Aortic Dissection. AB - BACKGROUND: Presenting systolic blood pressure (SBP) is a powerful predictor of mortality in many cardiovascular settings, including acute coronary syndromes, cardiogenic shock, and acute heart failure. OBJECTIVES: This study evaluated the association of presenting SBP with in-hospital outcomes, specifically all-cause mortality, in acute aortic dissection (AAD). METHODS: The study included 6,238 consecutive patients (4,167 with type A and 2,071 with type B AAD) enrolled in the International Registry of Acute Aortic Dissection. Patients were stratified in 4 groups according to presenting SBP: SBP >150, SBP 101 to 150, SBP 81 to 100, or SBP <=80 mm Hg. RESULTS: The relationship between presenting SBP and in hospital mortality displayed a J-curve association, with significantly higher mortality rates in patients with very high SBP (26.3% for SBP >180 mm Hg in type A AAD, 13.3% for SBP >200 mm Hg in type B AAD; p = 0.005 and p = 0.018, respectively) as well as in those with SBP <=100 mm Hg (29.9% in type A, 22.4% in type B; p = 0.033 and p = 0.015, respectively). This relationship was mainly from increased rates of in-hospital complications (acute renal failure, coma, and mesenteric ischemia/infarction in patients with SBP >150 mm Hg; stroke, coma, cardiac tamponade, myocardial ischemia/infarction, and acute renal failure in patients with SBP <=80 mm Hg). Notably, presenting SBP <=80 mm Hg was independently associated with in-hospital mortality in both type A (p = 0.001) and type B AAD (p = 0.003). CONCLUSIONS: Presenting SBP showed a clear J-curve relationship with in-hospital mortality in patients with AAD. Although this association was related to increased rates of comorbid conditions at the edges of the curve, SBP <=80 mm Hg was an independent correlate of in-hospital mortality.

PMID- 29598865 TI - PET Assessment of Epicardial Intimal Disease and Microvascular Dysfunction in Cardiac Allograft Vasculopathy. AB - BACKGROUND: Cardiac allograft vasculopathy (CAV) is a leading cause of graft failure and death after heart transplantation. Absolute myocardial blood flow (MBF) quantification using rubidium 82 (Rb-82) positron emission tomography (PET) could enable evaluation of diagnostically challenging diffuse epicardial and microvascular disease in CAV. OBJECTIVES: The authors aimed to evaluate Rb-82 PET detection of CAV. METHODS: Consecutive transplant recipients undergoing coronary angiography were prospectively evaluated with PET, multivessel intravascular ultrasound (IVUS), and intracoronary hemodynamics. CAV was defined as International Society of Heart and Lung Transplantation CAV1-3 on angiography and maximal intimal thickness >=0.5 mm on IVUS. RESULTS: Forty patients (mean age 56 years, 4.8 years post-transplant) completed evaluation. CAV was detected in 32 patients (80%) by IVUS and 14 (35%) by angiography. PET correlated significantly with invasive coronary flow indices: r = 0.29, rate-pressure product-adjusted myocardial flow reserve (cMFR) versus coronary flow reserve; r = 0.28, relative flow reserve versus fractional flow reserve; and r = 0.37, coronary vascular resistance (CVR) versus index of microcirculatory resistance. Patients with CAV or microvascular dysfunction had reduced cMFR and stress MBF and increased CVR. Receiver operator characteristic curves demonstrated good accuracy of PET for CAV on IVUS (area under the curve 0.77 to 0.81) and optimal diagnostic cutoffs of cMFR <2.9, stress MBF <2.3, and CVR >55. Combined PET assessment for CAV yielded excellent >93% sensitivity (>65% specificity) for 1 abnormal parameter and >96% specificity (>55% sensitivity) for 2 abnormal parameters. CONCLUSIONS: Rb-82 PET flow quantification has high diagnostic accuracy for CAV, with potential for noninvasive evaluation after heart transplantation.

PMID- 29598867 TI - Role of Stress Kinase JNK in Binge Alcohol-Evoked Atrial Arrhythmia. AB - BACKGROUND: Excessive binge alcohol drinking has acute cardiac arrhythmogenic effects, including promotion of atrial fibrillation (AF), which underlies "Holiday Heart Syndrome." The mechanism that couples binge alcohol abuse with AF susceptibility remains unclear. We previously reported stress-activated c-Jun N terminal kinase (JNK) signaling contributes to AF development. This is interesting because JNK is implicated in alcohol-caused organ malfunction beyond the heart. OBJECTIVES: The purpose of this study was to detail how JNK promotes binge alcohol-evoked susceptibility to AF. METHODS: The authors found binge alcohol-exposure leads to activated JNK, specifically JNK2. Furthermore, binge alcohol induces AF (24- vs. 1.8-Hz burst pacing-induced episodes per attempt per animal), higher incidence of diastolic intracellular Ca2+ activity (Ca2+ waves, sarcoplasmic reticulum [SR] Ca2+ leakage), and membrane voltage (Vm) and systolic Ca2+ release spatiotemporal heterogeneity (DeltatVm-Ca). These changes were completely eliminated by JNK inhibition both in vivo and in vitro. calmodulin kinase II (CaMKII) is a proarrhythmic molecule known to drive SR Ca2+ mishandling. RESULTS: The authors report for the first time that binge alcohol activates JNK2, which subsequently phosphorylates the CaMKII protein, enhancing CaMKII-driven SR Ca2+ mishandling. CaMKII inhibition eliminates binge alcohol evoked arrhythmic activities. CONCLUSIONS: Our studies demonstrate that binge alcohol exposure activates JNK2 in atria, which then drives CaMKII activation, prompting aberrant Ca2+ waves and, thus, enhanced susceptibility to atrial arrhythmia. Our results reveal a previously unrecognized form of alcohol-driven kinase-on-kinase proarrhythmic crosstalk. Atrial JNK2 function represents a potential novel therapeutic target to treat and/or prevent AF. PMID- 29598869 TI - Angiotensin-Converting Enzyme Inhibitors in Hypertension: To Use or Not to Use? AB - Most guidelines for the management of patients with cardiovascular disease recommend angiotensin-converting enzyme (ACE) inhibitors as first-choice therapy, whereas angiotensin receptor blockers (ARBs) are merely considered an alternative for ACE inhibitor-intolerant patients. The aim of this review was to compare outcomes and adverse events between ACE inhibitors and ARBs in patients. In patients with hypertension and hypertension with compelling indications, we found no difference in efficacy between ARBs and ACE inhibitors with regard to the surrogate endpoint of blood pressure and outcomes of all-cause mortality, cardiovascular mortality, myocardial infarction, heart failure, stroke, and end stage renal disease. However, ACE inhibitors remain associated with cough and a very low risk of angioedema and fatalities. Overall withdrawal rates because of adverse events are lower with ARBs than with ACE inhibitors. Given the equal outcome efficacy but fewer adverse events with ARBs, risk-to-benefit analysis in aggregate indicates that at present there is little, if any, reason to use ACE inhibitors for the treatment of hypertension or its compelling indications. PMID- 29598870 TI - Cardiac Implantable Electronic Devices in Patients With Left Ventricular Assist Systems. AB - Recent progress and evolution in device engineering, surgical implantation practices, and periprocedural management have advanced the promise of durable support with left ventricular assist systems (LVAS) in patients with stage D heart failure. With greater uptake of LVAS globally, a growing population of LVAS recipients have pre-existing cardiac implantable electronic devices (CIEDs). Strategies for optimal clinical management of CIEDs in patients with durable LVAS are evolving, and clinicians will increasingly face complex decisions regarding implantation, programming, deactivation, and removal of CIEDs. Traditional decision-making pathways for CIEDs may not apply to LVAS-supported patients, as few patients die of arrhythmic causes and many arrhythmias may be well tolerated. Given limited data, treatment decisions must be individualized and made collaboratively among electrophysiologists, advanced heart failure specialists, and patients and their caregivers. Large, prospective, well-conducted studies are needed to better understand the contemporary utility of CIEDs in patients with newer-generation LVAS.

AB - To gain a better understanding of the dynamics of moose-vehicle collisions, we analyzed 96 videos of moose-vehicle interactions recorded by vehicle dash-mounted cameras (Dash Cams) that had been posted to the video-sharing website YouTubeTM. Our objective was to determine the effects of road conditions, season and weather, moose behavior, and driver response to actual collisions compared to near misses when the collision was avoided. We identified 11 variables that were consistently observable in each video and that we hypothesized would help to explain a collision or near miss. The most parsimonious logistic regression model contained variables for number of moose, sight time, vehicle slows, and vehicle swerves (AICcw = 0.529). This model had good predictive accuracy (AUC = 0.860, SE = 0.041). The only statistically significant variable from this model that explained the difference between moose-vehicle collisions and near misses was 'Vehicle slows'. Our results provide no evidence that road surface conditions (dry, wet, ice or snow), roadside habitat type (forested or cleared), the extent to which roadside vegetation was cleared, natural light conditions (overcast, clear, twilight, dark), season (winter, spring and summer, fall), the presence of oncoming traffic, or the direction from which the moose entered the roadway had any influence on whether a motorist collided with a moose. Dash Cam videos posted to YouTubeTM provide a unique source of data for road safety planners trying to understand what happens in the moments just before a moose-vehicle collision and how those factors may differ from moose-vehicle encounters that do not result in a collision.

AB - Quorum Sensing (QS) is a communication system used by numerous bacteria to synchronize their behavior according to the cell density. In this way, bacteria secrete and sense small mediating molecules, called autoinducers (AI), which concentration increases in the environment proportionally to bacterial cell number. QS induces major physiological and phenotypic changes such as virulence induction and biofilm formation. Biofilm represents a physical barrier which shelters bacteria poorly sensitive to antimicrobial treatments and favors the apparition of resistance mechanisms. Disturbing QS is referred to as quorum quenching (QQ). This strategy is used by microorganisms themselves to prevent the development of specific group behaviors. Two strategies are mainly employed: the use of quorum sensing inhibitors (QSI) and of quorum quenching enzymes (QQE) that degrades AI. Many studies have been dedicated to identifying QSI (natural or synthetic) as well as QQE and demonstrating their anti-virulence and anti-biofilm effects on numerous bacterial species. Synergistic effects between QQ and traditional treatments such as antibiotherapy or with reemerging phage therapy have been put forward. The efficiency of numerous QSI and QQE was thereby demonstrated either with in vitro or in vivo animal models leading to the development of medical devices containing QSI and QQE to improve already existing treatments. PMID- 29598882 TI - Aging resistance, mechanical properties and translucency of different yttria stabilized zirconia ceramics for monolithic dental crown applications. AB - OBJECTIVES: The dental market moves towards high-translucency monolithic zirconia dental crowns, which are usually placed either with - or without - a thin glaze layer. The microstructural features and the mechanical performances of these materials are still controversial, as well as their susceptibility to aging. This paper aims at studying these aspects in the current generation of zirconia dental crowns showing different degrees of translucency. METHODS: Four different commercial zirconia materials were investigated, including one standard 'full strength' 3Y-TZP and three grades with improved translucency. The microstructural features (phase composition and assemblage, grain size) were carefully studied, as well as mechanical properties (biaxial bending strength and indentation toughness), translucency and aging behavior (in autoclave at 134 degrees C). Aging was conducted on crowns with and without glaze to better represent clinical uses. RESULTS: Important differences are found in terms of microstructures among the materials in terms of cubic phase content and yttria in the tetragonal phase, leading to different optical, mechanical and aging resistance properties. We show that higher cubic phase content leads to better translucency and stability in water steam, but at the expense of strength and toughness. A compromise is always inevitable between translucency and aging resistance on one side and mechanical properties on the other side.

AB - INTRODUCTION: Nocturnal enuresis is known to be a common urinary bladder complication in children. Recent studies have associated vitamin D and omega-3 insufficiency with nocturnal enuresis. AIM: This was a 2-month randomized, placebo-controlled, double-blind trial to measure the effects of vitamin D, omega 3 supplements, and their combination on nocturnal enuresis among 7-15-year-old children. MATERIALS AND METHODS: Participants (180 children with nocturnal enuresis) were selected from children referred to the Pediatric ward of Imam Reza Clinic in Shiraz, Iran. Demographic information and anthropometric measures were taken. Fasting blood and urine samples were also collected, and serum vitamin D and urine prostaglandin E2 were measured before and after intervention. Enuretic children were randomly assigned to four groups: Group A, vitamin D (1000 IU/day); Group B, omega-3 (1000 mg/day); Group C, both omega-3 (1000 mg/day) and vitamin D (1000 IU/day); and Group D, placebo. RESULTS: The results suggested that the study groups were not significantly different regarding demographic and anthropometric measures at baseline. Comparison of different groups revealed that 44.4% of participants in Group A, 28.2% of Group B and 45% of Group C were cured from enuresis (P = 0.03). Serum 25(OH) D was significantly increased in Group A, but urine prostaglandin E2 was not significantly decreased in response to supplementation. Although supplementation with both Group A and Group B were found to be effective, the combined intervention did not increase the effect of each intervention solely. CONCLUSIONS: The results showed that supplementation with vitamin D and omega-3 could reduce the number of wet nights among 7-15-year old children with nocturnal enuresis. PMID- 29598885 TI - Equity in access to care in the era of health system reforms in Turkey. AB - OBJECTIVE: To evaluate access to healthcare from an equity perspective on the way toward Universal Health Coverage in Turkey. METHODS: The country representative data from 2006 to 2013 Turkey Income and Living Conditions Surveys were analyzed. Private household residents aged fifteen and older were asked for self-reported unmet need for medical care in the past twelve months. The dependent variable had three categories: no unmet need, unmet need due to cost, and unmet need due to availability (waiting list and distance problems). Predictors of unmet need were assessed by a multinomial logistic regression analysis. FINDINGS: The prevalence of unmet need declined between 2006 and 2013. While educational inequalities in declared unmet need also decreased, the income gradient becomes more important. In 2013, controlling for other factors, the propensity to report unmet need was 10 times higher for those in the poorest-income quintile compared to the richest (versus 7 times in 2006). CONCLUSION: Overall access to healthcare has gradually improved in Turkey in the health reform process, but 9% of people still declared unmet need due to cost in 2013, after the implementation of Universal Health Insurance. This was nearly four times the EU average. Unfavourable economic and labour market conditions can be challenges for effective universal health coverage. PMID- 29598884 TI - Outcome of clinical management in relatives of sudden cardiac death victims. AB - BACKGROUND: International guidelines recommend clinical assessment of the surviving first-degree relatives of sudden cardiac death (SCD) victims to identify a probable cause of death and protect surviving relatives. Only few studies have reported the outcome of clinical management and follow-up of relatives to SCD victims. METHODS: We performed a retrospective cohort study of the clinical and genetic assessment of surviving relatives of SCD victims referred to the Clinic of Inherited Cardiac Diseases at Aarhus University Hospital, Denmark, between 1995 and 2016. We studied clinical and autopsy findings on all cases of SCD among children and adults. Relatives were followed for adverse cardiovascular events including cardiac hospitalization, new-onset heart failure, coronary heart disease, malignant syncope or documented malignant ventricular arrhythmias, and death. RESULTS: We included 292 relatives of 56 SCD victims. During a median (interquartile range) follow-up of 3.3 (1.6-4.7) years twelve relatives experienced an adverse cardiovascular event of which only five were related to the inherited cardiac disease in the family. One developed dilated cardiomyopathy and one tachycardia induced heart failure, five suffered from ventricular tachycardia or a malignant syncope and received a secondary prophylactic Implantable Cardioverter Defibrillator, three had a coronary heart disease event and two died from old age. CONCLUSION: Relatives of SCD victims have a low rate of adverse cardiac events when guideline-based assessment and care is applied. PMID- 29598886 TI - Mapping existing hip and knee replacement registries in Europe. AB - The general shortage of evidence regarding benefits and harms of medical devices has been highlighted following the serious safety concerns with metal-on-metal hip replacements and silicone breast implants and was again pointed out in a recent survey of European Health Technology Assessment institutions. In this context the new European medical device regulation will enforce post-marketing surveillance of existing and new implants. The usefulness of registry data as a source of information for medical device real-world clinical performance and safety has been demonstrated. However, these data might be under-used by researchers and policy makers. One reason for this is the insufficient awareness of their existence. The aim of this review is to provide information to relevant stakeholders on the extent and breadth of the data currently collected in European joint replacement registries. We identified 24 registries, most of them of national coverage. Total numbers of primary total hip and knee replacements included were over 3.1 and 2.5 million records, respectively. The current focus of these registries is on whole-lifespan implant surveillance via revision rate monitoring, quality assessment of surgical and perioperative care, and hospital performance assessment. More recently, national and international comparison and benchmarking have increasingly become part of their endeavors.

AB - BACKGROUND: Gastrointestinal diffuse large B cell lymphoma (GI DLBCL) is the most common gastrointestinal lymphoma. However, there has not been a comprehensive investigation into the expression patterns of programmed cell death 1 (PD-1) and programmed cell death ligand 1(PD-L1) in GI DLBCL tissues. METHODS: PD-1 protein expression in tumor-infiltrating lymphocytes (TILs) was evaluated by immunohistochemical staining, and expression of PD-L1 was evaluated by using PD L1/PAX5 immunohistochemical double staining in 92 GI DLBCL specimens. RESULTS: The prevalence of positive PD-L1 expression (PD-L1 + ) in GI DLBCL cells and positive PD-L1 expression in non-cancer cells of the GI DLBCL microenvironment (microenvironmental PD-L1, mPD-L1) were 11.96% (11 of 92) and 41.98% (34 of 81), respectively. PD-L1 expression in GI DLBCL was significantly associated with involvement of extranodal sites >= 2 (P = 0.034) and mPD-L1 expression was significantly associated with ECOG performance status (score >= 2) (P = 0.041). PD-L1 expression and mPD-L1 expression had no prognostic significance (P > 0.05) on disease outcome. PD-1+ TILs were significantly lower in patients with extranodal site involvement (P = 0.011) and the quantity of PD-1 + TILs correlated positively with the level of PDL1 expression in non malignant microenvironment cells (P = 0.001). Patients with high levels of PD-1+ TILs had better prognosis (P = 0.0005). CONCLUSIONS: The expression patterns of PD-L1 in patients with GI DLBCL are different from patients with common DLBCL. Immunotherapies that target the PD-1/PD-L1 pathway may have therapeutic potential in GI DLBCL.

PMID- 29598890 TI - Closed-loop intracranial stimulation alters movement timing in humans. AB - BACKGROUND: A prime objective driving the recent development of human neural prosthetics is to stimulate neural circuits in a manner time-locked to ongoing brain activity. The human supplementary motor area (SMA) is a particularly useful target for this objective because it displays characteristic neural activity just prior to voluntary movement. OBJECTIVE: Here, we tested a method that detected activity in the human SMA related to impending movement and then delivered cortical stimulation with intracranial electrodes to influence the timing of movement. METHODS: We conducted experiments in nine patients with electrodes implanted for epilepsy localization: five patients with SMA electrodes and four control patients with electrodes outside the SMA. In the first experiment, electrocorticographic (ECoG) recordings were used to localize the electrode of interest during a task involving bimanual finger movements. In the second experiment, a real-time sense-and-stimulate (SAS) system was implemented that delivered an electrical stimulus when pre-movement gamma power exceeded a threshold. RESULTS: Stimulation based on real-time detection of this supra threshold activity resulted in significant slowing of motor behavior in all of the cases where stimulation was carried out in the SMA patients but in none of the patients where stimulation was performed at the control site. CONCLUSIONS: The neurophysiological correlates of impending movement can be used to trigger a closed loop stimulation device and influence ongoing motor behavior in a manner imperceptible to the subject. This is the first report of a human closed loop system designed to alter movement using direct cortical recordings and direct stimulation. PMID- 29598891 TI - Outcomes of dialysis patients with critical limb ischemia after revascularization compared with patients with normal renal function. AB - OBJECTIVE: An analysis was conducted of intermediate outcomes and possible influencing factors in patients with end-stage renal disease (ESRD) and critical limb ischemia after lower limb revascularization compared with patients with regular renal function (non-ESRD). METHODS: Data collection was performed by inquiry of the German multicenter registry of First-Line Treatments in Patients with Critical Limb Ischemia (CRITISCH); 102 ESRD patients and 674 non-ESRD patients were included. Four different therapy modalities were analysed: bypass surgery, endovascular therapy (EVT), femoral artery endarterectomy, and no vascular intervention (conservative treatment or primary major amputation). Predefined end points were amputation-free survival (AFS), death, major amputation, and reintervention. Cox regression models were built to analyze independent risk factors for outcome parameters. RESULTS: ESRD patients showed inferior results at 2 years in the rate of AFS (ESRD, 35.4%; non-ESRD, 67.2%; P < .001). Similarly, death rate (ESRD, 55.0%; non-ESRD, 20.7%; P < .001) and major amputation rate (ESRD, 24.5%; non-ESRD, 15.8%; P = .029) were significantly elevated for ESRD patients. The choice of therapeutic approach in ESRD did not influence the incidence of the investigated end points (death or major amputation: EVT, 56.9% vs bypass, 76.9% [P = .225]; death: EVT, 46.2% vs bypass, 61.5% [P = .372]; amputation: EVT, 15.4% vs bypass, 15.4% [P = 1.000]; reintervention: EVT, 32.3% vs bypass, 15.4% [P = .324]). Cox regression analysis indicated that dialysis patients carry a twofold increased hazard of death or major amputation (hazard ratio, 2.27; 95% confidence interval, 1.67-3.10; P < .001), and open surgical treatment (all patients combined) was associated with reduced risk of death compared with EVT (hazard ratio, 0.58; 95% confidence interval, 0.37-0.91; P = .017). Comorbidities were not found to have a noticeable impact on AFS, survival, reintervention, or major amputation. CONCLUSIONS: Two year AFS, overall survival, and freedom from major amputation were decreased in ESRD patients compared with non-ESRD patients with critical limb ischemia. Cardiovascular comorbidities were without significant impact on outcome parameters, whereas choice of treatment modality within the ESRD group did not influence AFS. Decision-making in ESRD as to choice of therapeutic approach in dialysis patients should notably account for the individual's lesion characteristics and vascular disease; surgical revascularization and EVT may be used as complementary options.

AB - Recent facial palsies are those in which fibrillations of the mimetic musculature remain detectable by electromyography (EMG). Such fibrillations generally cease 18-24 months after palsy onset. During this period, facial re-animation surgery seeks to supply new neural inputs to the facial nerve. Neural usable sources were divided into qualitative (contralateral facial nerve) and quantitative (hypoglossus and masseteric nerve), depending on the type of stimulus provided. To further improve the extent and quality of facial re-animation, we here describe a new surgical technique featuring triple neural inputs: the use of the masseteric nerve and 30% of the hypoglossus nerve fibres as quantitative sources was associated with the contralateral facial nerve (incorporated via two cross face nerve grafts) as a qualitative source in order to restore facial movements in 24 consecutive patients. The use of two quantitative motor nerve sources together with a qualitative neural source appears to improve re-animation after facial paralysis, despite earlier doubts as to whether patients could use different nerves to produce facial movements. In fact, movement was much improved. Smiling according to emotions and blinking seem to be better assured if cross-face nerve grafting is performed in two steps rather than one.

AB - BACKGROUND: The hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks. OBJECTIVES: The aim of this study was to assess the effects of hammock positioning on behavioral status, vital signs, and pain in very low birth weight preterm newborns. METHODS: This is a quasi-experimental/case series study in which premature infants (<1500g) were positioned in supine for one hour in a hammock. The preterm newborns were assessed 10min before, during (2, 20, 40, and 60min), and 10min after hammock positioning with the Brazelton Neonatal Behavioral Assessment Scale, vital signs and pain by the Neonatal Facial Coding System. RESULTS: 28 preterm infants between 28 and 36 weeks of gestational age were evaluated. Regarding the behavioral state, the preterm newborns progressively evolved to light or deep sleep during hammock positioning. There was a statistically significant reduction of the heart and respiratory rate from 2 to 60th minute in a hammock, which was maintained after the positioning. The oxygen saturation remained within normal values. No changes in pain scores were observed. CONCLUSION: The hammock positioning can be considered a safe method of positioning that can be used to reduce the stress levels in very low birth weight preterm newborns. We did not observe worsening in either pain or vital signs.

AB - BACKGROUND: ORTHO-1 is a European, multicentric, first in human clinical trial to prove safety and feasibility after surgical implantation of commercially available biphasic calcium phosphate bioceramic granules associated during surgery with autologous mesenchymal stromal cells expanded from bone marrow (BM hMSC) under good manufacturing practices, in patients with long bone pseudarthrosis. METHODS: Twenty-eight patients with femur, tibia or humerus diaphyseal or metaphyso-diaphyseal non-unions were recruited and surgically treated in France, Germany, Italy and Spain with 100 or 200 million BM-hMSC/mL associated with 5-10 cc of bioceramic granules. Patients were followed up during one year. The investigational advanced therapy medicinal product (ATMP) was expanded under the same protocol in all four countries, and approved by each National Competent Authority. FINDINGS: With safety as primary end-point, no severe adverse event was reported as related to the BM-hMSC. With feasibility as secondary end-point, the participating production centres manufactured the BM hMSC as planned. The ATMP combined to the bioceramic was surgically delivered to the non-unions, and 26/28 treated patients were found radiologically healed at one year (3 out of 4 cortices with bone bridging). INTERPRETATION: Safety and feasibility were clinically proven for surgical implantation of expanded autologous BM-hMSC with bioceramic. FUNDING: EU-FP7-HEALTH-2009, REBORNE Project (GA: 241876).

AB - Maternal behaviour (carrying of larvae on the opisthosoma) in ticks has thus far only been observed in Antricola (Parantricola) marginatus and was considered a unique derived adaptation of this genus. The authors extend this observation to two additional argasid species, namely Argas (Argas) striatus and Argas (Secretargas) transgariepinus. In addition, brooding behaviour over eggs were observed with A. (S.) transgariepinus. Maternal behaviour may be an evolutionary adaptation to ecological challenges in habitats unsuited for larval survival and may be related to the presence of pulvilli in larvae. This adaptation might have been present in the ancestral tick lineage since pulvilli occur in all tick families, and may have been derived from a more ancient adaptation in chelicerates where maternal behaviour was common. Female A. (S.) transgariepinus also possess a unique area on their ventral abdomen that is absent in males and may be a unique adaptation for maternal behaviour in this species. Phylogenetic analysis of the 16S rRNA genes for both species indicate that they are unique lineages that group basal to other members of the Argas genus, supporting the possibility that they harbour ancestral traits for this group.

PMID- 29598900 TI - Small-molecules that bind to the ubiquitin-binding motif of REV1 inhibit REV1 interaction with K164-monoubiquitinated PCNA and suppress DNA damage tolerance. AB - REV1 protein is a mutagenic DNA damage tolerance (DDT) mediator and encodes two ubiquitin-binding motifs (i.e., UBM1 and UBM2) that are essential for the DDT function. REV1 interacts with K164-monoubiquitinated PCNA (UbPCNA) in cells upon DNA-damaging stress. By using AlphaScreen assays to detect inhibition of REV1 and UbPCNA protein interactions along with an NMR-based strategy, we identified small molecule compounds that inhibit the REV1/UbPCNA interaction and that directly bind to REV1 UBM2. In cells, one of the compound prevented recruitment of REV1 to PCNA foci on chromatin upon cisplatin treatment, delayed removal of UV-induced cyclopyrimidine dimers from nuclei, prevented UV-induced mutation of HPRT gene, and diminished clonogenic survival of cells that were challenged by cyclophosphamide or cisplatin. This study demonstrates the potential utility of a small-molecule REV1 UBM2 inhibitor for preventing DDT. PMID- 29598901 TI - Macrocyclic alpha helical peptide therapeutic modality: A perspective of learnings and challenges. AB - Macrocyclic alpha-helical peptides have emerged as a compelling new therapeutic modality to tackle targets confined to the intracellular compartment. Within the scope of hydrocarbon-stapling there has been significant progress to date, including the first stapled alpha-helical peptide to enter into clinical trials. The principal design concept of stapled alpha-helical peptides is to mimic a cognate (protein) ligand relative to binding its target via an alpha-helical interface. However, it was the proclivity of such stapled alpha-helical peptides to exhibit cell permeability and proteolytic stability that underscored their promise as unique macrocyclic peptide drugs for intracellular targets. This perspective highlights key learnings as well as challenges in basic research with respect to structure-based design, innovative chemistry, cell permeability and proteolytic stability that are essential to fulfill the promise of stapled alpha helical peptide drug development.

PMID- 29598903 TI - Regulatory perspective on in vitro potency assays for human T cells used in anti tumor immunotherapy. AB - The adaptive immune system is known to play an important role in anti-neoplastic responses via induction of several effector pathways, resulting in tumor cell death. Because of their ability to specifically recognize and kill tumor cells, the potential use of autologous tumor-derived and genetically engineered T cells as adoptive immunotherapy for cancer is currently being explored. Because of the variety of potential T cell-based medicinal products at the level of starting material and manufacturing process, product-specific functionality assays are needed to ensure quality for individual products. In this review, we provide an overview of in vitro potency assays suggested for characterization and release of different T cell-based anti-tumor products. We discuss functional assays, as presented in scientific advices and literature, highlighting specific advantages and limitations of the various assays. Because the anticipated in vivo mechanism of action for anti-tumor T cells involves tumor recognition and cell death, in vitro potency assays based on the cytotoxic potential of antigen-specific T cells are most evident. However, assays based on other T cell properties may be appropriate as surrogates for cytotoxicity. For all proposed assays, biological relevance of the tests and correlation of the read-outs with in vivo functionality need to be substantiated with sufficient product-specific (non )clinical data. Moreover, further unraveling the complex interaction of immune cells with and within the tumor environment is expected to lead to further improvement of the T cell-based products. Consequently, increased knowledge will allow further optimized guidance for potency assay development. PMID- 29598904 TI - Lipopolysaccharide Induces Subacute Cerebral Microhemorrhages with Involvement of Nitric Oxide Synthase in Rats. AB - BACKGROUND: Cerebral microhemorrhage (CMH) is a neuropathological term that could be easily found in cerebral amyloid angiopathy, intracerebral hemorrhages, etc. CMHs could be detected clearly in vivo by magnetic resonance imaging (MRI) susceptibility-weighted imaging or MRI T2* scan. This terminology is now accepted in the area of neuroimaging. CMHs are quite common in elderly patients and are associated with several other neuropsychiatric disorders. The causes of CMHs are complicated, and neuroinflammation is considered as one of the well-accepted mechanical factors. This study investigated whether lipopolysaccharide (LPS) induced CMHs occur through the regulation of nitric oxide synthase (NOS) isoforms and reveals the exact underlying mechanism of LPS-induced CMHs. METHODS: Our work successfully developed a subacute model of CMHs in rats. LPS was intraperitoneally injected into rats at 0, 6, and 24 hours, which induced typical CMH features 7 days after the injection. These could be detected on the brain surface or parenchyma by hematoxylin and eosin staining and MRI. RESULTS: LPS treated rats showed significant activation of astrocytes and microglia, as well as loss of pericytes and disruption of blood-brain barrier. Meanwhile, both astrocytes and microglia were positively correlated with CMH numbers. Furthermore, the expressions of NOS isoforms were also examined, and the levels of neuronal NOS and endothelial NOS were found to be elevated. CONCLUSIONS: These results implied that the NOS isoforms might be involved in the subacute model of CMHs in rats induced by LPS. PMID- 29598905 TI - The Accuracy of Serum Matrix Metalloproteinase-9 for Predicting Hemorrhagic Transformation After Acute Ischemic Stroke: A Systematic Review and Meta Analysis. AB - BACKGROUND: Hemorrhagic transformation is a serious complication of acute ischemic stroke, which may cause detrimental outcomes and the delayed use of anticoagulation therapy. Early predicting and identifying the patients at high risk of hemorrhagic transformation before clinical deterioration occurrence become a research priority. OBJECTIVE: To study the value of plasma matrix metalloproteinase-9 predicting hemorrhagic transformation after ischemic stroke. METHODS: We searched PubMed, Ovid, Cochrane Library, and other 2 Chinese databases to identify literatures published up to September 2017 and performed meta-analysis by STATA (version 12.0, StataCorp LP, College Station, TX). RESULTS: Twelve studies incorporating 1492 participants were included and 7 studies were included in the quantitative statistical analysis. The pooled sensitivity was 85% (95% confidence interval [CI]: 75%, 91%) and the pooled specificity was 79% (95% CI: 67%, 87%). The area under the receiver operating characteristic curve was .89 (95% CI .86, .91). Significant heterogeneity for all estimates value existed (all the P value < .05 and I2 > 50%). There is no threshold effect with P value greater than .05 of the correlation coefficient. Meta-regression and subgroup analysis showed cut-off value and hemorrhagic subtype contributed to heterogeneity. Deeks' funnel plot indicated no significant publication bias for 7 quantitative analysis studies. CONCLUSIONS: Matrix metalloproteinase-9 has high predictive value for hemorrhagic transformation after acute ischemic stroke. It may be useful to test matrix metalloproteinase-9 to exclude patients at low risk of hemorrhage for precise treatment in the future clinical work. PMID- 29598906 TI - Posterior Meningeal Artery Origin Patterns among 300 Cases and Their Clinical Importance. AB - BACKGROUND AND PURPOSE: The posterior meningeal artery (PMA) is known as a dura mater-nourishing vessel. We encountered a patient with Wallenberg syndrome during transarterial embolization of the PMA associated with the dural arteriovenous fistula (DAVF). METHODS: After development of Wallenberg syndrome in the patient, we assessed origins of the PMA patterns in 300 cases and divided them into 3 types. CASE PRESENTATION: A 63-year-old man was incidentally diagnosed as having transverse-sigmoid sinus DAVF with a cortical venous reflux. During the transarterial embolization, the patient complained of vertigo and numbness of the right extremities. Postoperatively, the patient exhibited Wallenberg syndrome. Diffusion-weighted magnetic resonance imaging showed a high-intensity area on the lateral side of the right medulla. CONCLUSIONS: While performing arterial embolization of the PMA that directly originates from the intracranial vertebral artery, the possibility of deficient brainstem nourishment must be considered. PMID- 29598907 TI - Upstream Stimulating Factor 1 (USF-1) Gene Polymorphisms and the Risk, Symptoms, and Outcome of Pediatric Ischemic Stroke. AB - BACKGROUND: Pediatric ischemic stroke is an important cause of morbidity and mortality. As previous studies of children after stroke showed, dyslipidemias were very common in Polish and other European populations. Thus, looking for genetic factors predisposing to pediatric stroke, its symptoms, and outcome, we have analyzed 2 polymorphisms of the upstream stimulating factor 1 (USF-1) gene. MATERIALS AND METHODS: The study group consisted of 82 children with stroke, 156 parents, and 146 controls. We used 2 alternative methods: the case-control model and the analysis of families using the transmission disequilibrium test. The 2 polymorphisms, rs2516839 and rs3737787, were genotyped using the TaqMan Pre Designed SNP Genotyping Assay. The Statistica 10.0 software was used in all statistical analyses. RESULTS: We did not observe any statistical differences in genotype and allele frequencies between patients and controls. There were also no significant differences in the transmission of alleles from the parents to the affected children. However, we have observed that the TT genotype of the rs2516839 polymorphism was more common in patients with epilepsy and dysarthria, whereas the TT genotype of the rs3737787 polymorphism was more frequent in the group of patients with a decrease in intellectual functioning. CONCLUSIONS: Our study did not show any associations between the 2 analyzed polymorphisms of the USF-1 gene and pediatric ischemic stroke. However, we have observed an influence of specific genotypes on the outcome of stroke, including epilepsy, dysarthria, and a decrease in intellectual functioning. PMID- 29598908 TI - Effects of Posturographic Platform Biofeedback Training on the Static and Dynamic Balance of Older Stroke Patients. AB - BACKGROUND: The aim of the experiment was to analyze the influence of posturographic platform biofeedback training on the static and dynamic balance of patients who experienced ischemic stroke. MATERIALS AND METHODS: The study included 20 patients treated at the Rehabilitation Center of the District Hospital in Bialogard, in the Ward of Neurological Rehabilitation with the Stroke Division. The age of the patients (10 in the experimental group and 10 in the control group) ranged between 60 and 72 years. The level of balance was determined with one-leg standing test and timed up & go test. The experimental group was subjected to the biofeedback training, practicing maintenance of body balance ("forced sway training") on posturographic platform for 15 consecutive days. RESULTS: The static balance on right leg and dynamic balance in group E improved to a markedly greater extent (P < .05) compared with conventionally rehabilitated group C. CONCLUSIONS: The effects of feedback mechanisms during training on a posturographic platform can be reflected by enhanced stimulation and further improvement of the control of different, more complicated performed motor tasks.

AB - Herein described the design, synthesis and antitubercular evaluation of novel series of dibenzofuran, dibenzothiophene and N-methyl carbazole tethered 2 aminothiazoles and their cinnamamide analogs. One pot condensation of N-methyl carbazole, dibenzofuran and dibenzothiophene methyl ketones with thiourea in the presence of Iodine and CuO gave respective 2-aminothiazoles 4-6 in very good yields. Aminothiazoles were further coupled with substituted cinnamic acids using acid-amine coupling conditions to give desired cinnamamide analogs 8a-e, 9a-e and 10a-e. All the newly synthesized compounds were fully characterized by their NMR and mass spectral analysis. In vitro screening of new derivatives against Mycobacterium tuberculosis H37Rv (Mtb) resulted 8c, 10d and 10e (MIC: 0.78 ug/mL) and 2-aminothiazoles 5 and 6 (MIC: 1.56 ug/mL) as potent compounds with lower cytotoxicity profile. PMID- 29598910 TI - Site-specific effect of polar functional group-modification in lipids of TLR2 ligands for modulating the ligand immunostimulatory activity. AB - Toll-like receptor 2 (TLR2), a member of the TLR innate immune receptor family, recognizes lipoproteins from bacteria and modulates the immune response by inducing the expression of various cytokines. TLR2 has a large hydrophobic pocket that recognizes long fatty acyl groups on TLR2 ligands. However, few studies have focused on the property of the hydrophobic TLR2 pocket. Based on the X-ray crystal structure of TLR2, small polar regions were found in the hydrophobic TLR2 pocket. Interactions between the polar residues and ligands were explored here by designing and synthesizing a Pam2CSK4 derivative of the TLR2 ligands, containing an amide group within the lipid moiety. We evaluated the binding affinities and immunomodulatory activities of these ligands. Results suggested that the amide groups in the lipid chain interacted with the polar residues in the hydrophobic lipid-binding pocket of TLR2.

AB - The discovery of two quinazolinones with selective, single-digit micromolar activity (IC50 = 6-7 uM) against the tachyzoites of the apicomplexan parasite Toxoplasma gondii is reported. These potent and selective third generation derivatives contain a benzyloxybenzyl substituent at C2 and a bulky aliphatic moiety at N3. Here we show that these quinazolinones inhibit T. gondii tachyzoite replication in an established infection, but do not significantly affect host cell invasion by the tachyzoites. PMID- 29598912 TI - Novel purine benzimidazoles as antimicrobial agents by regulating ROS generation and targeting clinically resistant Staphylococcus aureus DNA groove. AB - A novel series of purine benzimidazole hybrids were designed and synthesized for the first time with the aim to circumvent the increasing antibiotic resistance. Hexyl appended hybrid 3c gave potent activities against most of the tested bacteria and fungi especially against multidrug-resistant strains Staphylococcus aureus (MIC = 4 ug/mL). Structure-activity relationships revealed that the benzimidazole fragment at the 9-position of purine played an important role in exerting potentially antibacterial activity. Both cell toxicity and ROS generation assays indicated that the purine derivative 3c showed low cytotoxicity and could be used as a safe agent. Molecular modeling suggested that hybrid 3c could bind with the residues of Topo IA through hydrogen bonds and electrostatic interactions. Quantum chemical studies were also performed on the target compound 3c to understand the structural features essential for activity. The active molecule 3c could effectively interact with S. aureus DNA to form 3c-DNA complex through groove binding mode, which might block DNA replication to display their powerful antimicrobial activity. PMID- 29598913 TI - Geriatric radiotherapy in a war-torn country: Experience from Iraq. AB - INTRODUCTION: Cancer prevalence and geriatric patients (GP) are increasing and about half of the patients with cancer will be offered radiotherapy (RT). Addressing GP and their RT needs is an important issue in order to understand this heterogeneous group of patients. MATERIALS AND METHODS: A descriptive cross sectional study, using a convenience sample from Sulaimani city's inhabitants, aged 70-year and more, who were treated with RT at the only city's RT center, Zhianawa Cancer Center (ZCC), in 2015. RESULTS: 153 patients' charts were reviewed. GP represented 20% of the patients referred to ZCC. Male: Female ratio was 3:1. One third presented with distant metastases, and 46% were treated with curative intent versus 54% with palliative intent. 94% completed the planned sessions of the curative RT vs 90% of the palliative RT. 23% of GP who were referred for RT didn't receive it. 9% got interruptions during RT course. 10% of GP living >40 km away from the treatment center refused treatment. Mean time interval between the date of referral and the date of starting treatment in the palliative setting was 19 days. Only 41% of patients with curative setting had regular follow-up. CONCLUSIONS: Being the 1st study in this regard in a war-torn nation, Iraq, our results demonstrated that GP is a sizable group of ZCC patients and that RT is a valuable modality in GP cancer treatment. "Age per se" is not a factor to avoid this modality when there is an indication to use it. Longer distance to reach the center was a challenge in some of our GP. Due to inadequate number of RT machines, GP have to wait long time before getting their RT, even for palliative purposes. Further studies in this field are warranted.

AB - INTRODUCTION: Three-vessel coronary artery disease is an advanced manifestation of atherosclerosis, with high prevalence in Mexico. OBJECTIVE: The aim of this study was to describe coronary risk factors in a group of patients with three vessel coronary artery disease in Northwest Mexico. METHODS: A cross sectional study was conducted on a population with three-vessel coronary artery disease from May 2015 to February 2016. The disease was defined when >=70% stenosis was present in each major epicardial coronary artery. Anthropometric and biochemical parameters were measured in each patient. Ankle-Brachial Index was measured with vascular ultrasound, and Syntax score calculation with an on-line application. Statistical analysis for qualitative differences was performed using Pearson X2 test, with p<0.05 being considered as significant. RESULTS: The study included 100 patients, of whom 75 were male (mean age 63+/-9 years) and 25 female (mean age 69+/-9 years). The coronary risk factors observed were diabetes (58%), hypertension (86%), smoking (68%), dyslipidaemia (100%), metabolic syndrome (71%), and obesity/overweight (75%). Diabetes and metabolic syndrome prevalence was higher in women (p=0.03), but smoking was higher in men (76%, p=0.003). Ankle Brachial Index was abnormal in 58% of patients, the mean Syntax score was in 36.9+/-11.5, and the prevalence of left main coronary heart disease was 36%. CONCLUSIONS: This group of patients with complex coronary lesions has a high prevalence of coronary risk factors, which could represent a worse prognosis.

PMID- 29598920 TI - Amphioxus neurocircuits, enhanced arousal, and the origin of vertebrate consciousness. AB - Gene expression studies have recently identified the amphioxus homolog of a domain comprising the combined caudal diencephalon plus midbrain, regions implicated in locomotory control and some forms of primary consciousness in vertebrates. The results of EM-level reconstructions of the larval brain of amphioxus, reviewed here, highlight the importance of inputs to this region for light and physical contact, both of which impinge on the same synaptic zone. The neural circuitry provides a starting point for understanding the organization and evolution of locomotory control and arousal in vertebrates, and implies that one of the tasks of midbrain-based consciousness, as it first emerged in vertebrates, would have been to distinguish between light and physical contact, probably sharp pain in the latter case, by assigning different qualia to each. If so, investigating midbrain circuitry more fully could lead to a better understanding of the neural basis of some forms of sensory experience.

AB - Neuropathic pain-pain caused by a lesion or disease of the somatosensory nervous system-is underdiagnosed and difficult to treat. However, development of easy-to use questionnaires based mainly on self-reports of symptoms has improved diagnosis and management. Two types of questionnaires (screening and assessment) have been validated, and rapidly translated and revalidated in several languages, probably because of their simplicity. Screening questionnaires help clinicians to identify neuropathic pain easily, particularly in patients with complex medical conditions (eg, spinal cord injury). Their use in large-scale epidemiological studies has provided estimates of the prevalence of neuropathic pain and identified risk factors for neuropathic pain in the general population and in disorders such as diabetes. Assessment questionnaires measure neuropathic symptoms and have been used to create phenotypic profiles of patients in various neuropathic conditions. These profiles can predict treatment outcomes, and thus enable a personalised therapeutic approach. The dissemination of these questionnaires in different countries should further improve diagnosis and management worldwide and advance knowledge on the mechanisms of neuropathic pain. PMID- 29598924 TI - Oncentra brachytherapy planning system. AB - In modern cancer management, treatment planning has progressed as a contemporary tool with all the advances in computing power in recent years. One of the advanced planning tools uses 3-dimensional (3D) data sets for accurate dose distributions in patient prescription. Among these planning processes, brachytherapy has been a very important part of a successful cancer management program, offering clinical benefits with specific or combined treatments with external beam therapy. In this chapter, we mainly discussed the Elekta Oncentra planning system, which is the main treatment planning tool for high-dose rate (HDR) modality in our facility and in many other facilities in the United States. HDR is a technically advanced form of brachytherapy; a high-intensity radiation source (3.6 mm in length) is delivered with step motor in submillimeter precision under computer guidance directly into the tumor areas while minimizing injury to surrounding normal healthy tissue. Oncentra planning is the key component to generate a deliverable brachytherapy procedure, which is executed on the microSelectron V3 remote afterloader treatment system. Creating a highly conformal plan can be a time-consuming task. The development of Oncentra software (version 4.5.3) offers a variety of useful tools that facilitate many of the clinical challenging tasks for planning, such as contouring and image reconstruction, as well as rapid planning calculations with dose and dose volume histogram analysis. Oncentra Brachy module creates workflow and optimizes the planning accuracy for wide varieties of clinical HDR treatments, such as skin, gynecologic (GYN), breast, prostate, and many other applications. The treatment file can also be transferred to the afterloader control station for speedy delivery. The design concept, calculation algorithms, and optimization modules presented some key characteristics to plan and treat the patients effectively and accurately. The dose distribution and accuracy of several clinical sample cases were discussed to illustrate the effectiveness and clinical efficacy. The American Association of Physicists in Medicine brachytherapy reports of TG-43 and TG-186 were also described and compared in evaluations of fundamental calculation methodologies. PMID- 29598923 TI - Prognosis for patients with amyotrophic lateral sclerosis: development and validation of a personalised prediction model. AB - BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive, fatal motor neuron disease with a variable natural history. There are no accurate models that predict the disease course and outcomes, which complicates risk assessment and counselling for individual patients, stratification of patients for trials, and timing of interventions. We therefore aimed to develop and validate a model for predicting a composite survival endpoint for individual patients with ALS. METHODS: We obtained data for patients from 14 specialised ALS centres (each one designated as a cohort) in Belgium, France, the Netherlands, Germany, Ireland, Italy, Portugal, Switzerland, and the UK. All patients were diagnosed in the centres after excluding other diagnoses and classified according to revised El Escorial criteria. We assessed 16 patient characteristics as potential predictors of a composite survival outcome (time between onset of symptoms and non-invasive ventilation for more than 23 h per day, tracheostomy, or death) and applied backward elimination with bootstrapping in the largest population-based dataset for predictor selection. Data were gathered on the day of diagnosis or as soon as possible thereafter. Predictors that were selected in more than 70% of the bootstrap resamples were used to develop a multivariable Royston-Parmar model for predicting the composite survival outcome in individual patients. We assessed the generalisability of the model by estimating heterogeneity of predictive accuracy across external populations (ie, populations not used to develop the model) using internal-external cross-validation, and quantified the discrimination using the concordance (c) statistic (area under the receiver operator characteristic curve) and calibration using a calibration slope. FINDINGS: Data were collected between Jan 1, 1992, and Sept 22, 2016 (the largest data-set included data from 1936 patients). The median follow-up time was 97.5 months (IQR 52.9-168.5). Eight candidate predictors entered the prediction model: bulbar versus non-bulbar onset (univariable hazard ratio [HR] 1.71, 95% CI 1.63-1.79), age at onset (1.03, 1.03-1.03), definite versus probable or possible ALS (1.47, 1.39-1.55), diagnostic delay (0.52, 0.51-0.53), forced vital capacity (HR 0.99, 0.99-0.99), progression rate (6.33, 5.92-6.76), frontotemporal dementia (1.34, 1.20-1.50), and presence of a C9orf72 repeat expansion (1.45, 1.31-1.61), all p<0.0001. The c statistic for external predictive accuracy of the model was 0.78 (95% CI 0.77-0.80; 95% prediction interval [PI] 0.74-0.82) and the calibration slope was 1.01 (95% CI 0.95-1.07; 95% PI 0.83-1.18). The model was used to define five groups with distinct median predicted (SE) and observed (SE) times in months from symptom onset to the composite survival outcome: very short 17.7 (0.20), 16.5 (0.23); short 25.3 (0.06), 25.2 (0.35); intermediate 32.2 (0.09), 32.8 (0.46); long 43.7 (0.21), 44.6 (0.74); and very long 91.0 (1.84), 85.6 (1.96). INTERPRETATION: We have developed an externally validated model to predict survival without tracheostomy and non-invasive ventilation for more than 23 h per day in European patients with ALS. This model could be applied to individualised patient management, counselling, and future trial design, but to maximise the benefit and prevent harm it is intended to be used by medical doctors only.

AB - The objective of this project is to evaluate the percentage dose reduction in cardiac implantable electronic devices (CIEDs) using a thermoplastic wrapped lead sheet. The dose to CIED is evaluated in various situations with and without a lead shield. The efficiency of this type of shielding is supported by measurements made with a commercial plastic scintillation detector (PSD). Percentage depth dose (PDD) curve and lateral dose measurements (LDMs) were made with and without shielding for photon and electron beams. Photon LDMs were made at a depth of 0.5 cm. PSD measurements were compared with dose calculation from the treatment planning system (TPS). The benefit of shielding is greater at 23 MV than at 6 MV, with an average reduction of 71% and 59% of dose, respectively, for out-of-field distance range between 3 and 15 cm. Measurement of posterior beams shows there is no significant increase in skin dose due to backscatter from the lead sheet even when the field intercepts it. Large deviations between TPS calculation and measurements have been observed. The use of lead shielding with an anterior field is advised and provides an easy way to decrease the cumulative dose to CIEDs. Interception of shielding by an electron beam would increase significantly the cumulative dose to CIED for high energies or decrease the quality of the treatment. For a posterior out-of-field, shielding does not have a significant impact on CIED dose. PMID- 29598926 TI - Effects of heterogeneities in dose distributions under nonreference conditions: Monte Carlo simulation vs dose calculation algorithms. AB - The purpose of this study is to evaluate the performance of dose calculation algorithms used in radiotherapy treatment planning systems (TPSs) in comparison with Monte Carlo (MC) simulations in nonelectronic equilibrium conditions. MC simulations with PENELOPE package were performed for comparison of doses calculated by pencil beam convolution (PBC), analytical anisotropy algorithm (AAA), and Acuros XB TPS algorithms. Relative depth dose curves were calculated in heterogeneous water phantoms with layers of bone (1.8 g/cm3) and lung (0.3 g/cm3) equivalent materials for radiation fields between 1 * 1 cm2 and 10 * 10 cm2. Analysis of relative depth dose curves at the water-bone interface shows that PBC and AAA algorithms present the largest differences to MC calculations (uMC = 0.5%), with maximum differences of up to 4.3% of maximum dose. For the lung-equivalent material and 1 * 1 cm2 field, differences can be up to 24.3% for PBC, 11.5% for AAA, and 7.5% for Acuros. Results show that Acurus presents the best agreement with MC simulation data with equivalent accuracy for modeling radiotherapy dose deposition especially in regions where electronic equilibrium does not hold. For typical (nonsmall) fields used in radiotherapy, AAA and PBC can exhibit reasonable agreement with MC results even in regions of heterogeneities.

AB - BACKGROUND: Hip fracture risk is high in young people with multiple sclerosis (MS), but has not been examined in an institutionalized aging population with MS. OBJECTIVE: We aimed to compare the hip fracture risk in nursing home (NH) residents with and without MS; and (2) examine risk factors for hip fracture in those with MS. METHODS: We conducted a retrospective cohort study using national NH clinical assessment and Medicare claims data. Participants included age-, sex- and race-matched NH residents with/without MS (2007-2008). Multivariable competing risk regression was used to compare 2-year hip fracture risk, and to examine risk factors. RESULTS: A total of 5692 NH residents with MS were matched to 28,460 without MS. Approximately 80% of residents with MS vs. 50% of those without MS required extensive assistance in walking at NH admission. The adjusted incidence rate of hip fracture was 7.1 and 18.6 per 1000 person-years in those with or without MS, respectively. Wandering and anxiolytic exposure were the main hip fracture risk factors in transfer independent residents with MS; while pneumonia and antidepressant use were the main factors in dependent residents with MS. CONCLUSIONS: In contrast to prior comparisons from non-NH populations, the incidence of hip fracture was lower in NH residents with MS as compared with matched controls. Residents with MS were much more functionally dependent, which likely explains these findings. Fracture prevention strategies should focus on fall prevention in independent residents; and possibly improvement of health status and facility quality of care in dependent residents. PMID- 29598929 TI - Relationship of the Duke jeopardy score combined with minimal lumen diameter as assessed by computed tomography angiography to the hemodynamic relevance of coronary artery stenosis. AB - OBJECTIVES: To study the diagnostic performance of the ratio between the Duke jeopardy score (DJS) and the minimal lumen diameter (MLD) (DJS/MLDCT ratio) as assessed by coronary computed tomographic angiography (CTA) for differentiating functionally significant from non-significant coronary artery stenoses, with reference to invasive fractional flow reserve (FFR). METHODS: Patients who underwent both coronary CTA and FFR measurement during invasive coronary angiography (ICA) within 2 weeks were retrospectively included in the study. Invasive FFR measurement was performed in patients with intermediate to severe coronary stenoseis. DJS/MLDCT ratio and anatomical parameters were recorded. Lesions with FFR <=0.80 were considered to be functionally significant. RESULTS: One hundred and sixty-one patients with 175 lesions were included into the analysis. Diameter stenosis in CT, area stenosis, plaque burden, lesion length (LL), ICA-based stenosis degree, DJS, LL/MLD4 ratio, DJS/MLA ratio as well as DJS/MLD ratio were all significantly different between hemodynamically significant and non-significant lesions (p<0.05 for all). ROC curve analysis determined the optimal cut-off value for DJS/MLDCT ratio to be 1.96 (area under curve = 0.863, 95 % confidence interval = 0.803-0.910), yielding a high diagnostic accuracy (86.9%, 152/175). CONCLUSIONS: In coronary artery stenoses detected by coronary CTA, the DJS/MLD ratio is able to predict hemodynamic relevance.

PMID- 29598931 TI - TARC expression in the circulation and cutaneous granulomas correlates with disease severity and indicates Th2-mediated progression in patients with sarcoidosis. AB - BACKGROUND: Sarcoidosis is a systemic disorder characterized by the accumulation of lymphocytes and monocyte/macrophage lineage cells that results in the formation of non-caseating granulomas. Thymus- and activation-regulated chemokine (TARC)/CCL17 is an important chemokine in the amplification of Th2 responses, which are achieved by recruiting CCR4-expressing CD4+ T lymphocytes. TARC concentrations are known to increase in the serum of sarcoidosis patients; however, its role in the assessment of severity and prognosis of sarcoidosis remains unknown. The objective of this study is to elucidate the role of TARC in sarcoidosis by investigating its expression in peripheral blood and at inflammatory sites. We also examined its relationship with clinical features. METHODS: Serum levels of TARC, soluble interleukin 2 receptor, angiotensin converting enzyme, and lysozyme were measured in 82 sarcoidosis patients. The Th1 and Th2 balance in circulating CD4+ T cells was evaluated by flow cytometry. The immunohistochemical staining of TARC and CCR4 was performed in order to identify the source of TARC in affected skin tissues. RESULTS: TARC serum levels were elevated in 78% of patients and correlated with disease severity. The percentage of CCR4+ cells and the CCR4+/CXCR3+ cell ratios were significantly higher in sarcoidosis patients than in normal subjects (P = 0.002 and P = 0.015, respectively). Moreover, TARC was expressed by monocyte/macrophage lineage cells within granulomas. The abundancy as well as distribution of TARC staining correlated with its serum levels. CONCLUSIONS: The present results suggest that elevations in TARC drive an imbalanced Th2- weighted immune reaction and might facilitate prolonged inflammatory reactions in sarcoidosis. PMID- 29598932 TI - Glucagon like peptide-1 (GLP-1) likes Alzheimer's disease. AB - Glucagon-like peptide-1 (GLP-1) is a 30 amino acid long peptide hormone derived from the proglucagon gene and secreted in the distal small intestine when food enters the duodenum. GLP-1 is also produced in the central nervous system (CNS), predominantly in the brainstem, and subsequently transported to a large number of regions in the CNS. Neuronal cells in nucleus tractus solitarius (NTS) can synthesize GLP-1 and extends to hypothalamus, some thalamic and cortical areas. A G protein coupled receptor (GPCR) provides the majority of GLP-1 actions. GLP-1 receptor activation triggers some in vivo signaling pathways. GLP-1 receptor agonists (GLP-1 RA) are used in the treatment diabetes and obesity. GLP-1 stimulates insulin secretion, inhibits glucagon secretion, decreases food intake, reduces appetite, delays gastric emptying, provides weight reduction, and protects beta cells from apoptosis. Alzheimer's disease (AD) is the most prevalent form of dementia. It is characterized by cognitive insufficiencies and behavioral changes that impact memory and learning abilities, daily functioning and quality of life. Hyperinsulinemia and insulin resistance, which are known as pathophysiological features of the T2DM, have also been demonstrated to have significant impact on cognitive impairment. It is thought that GLP-1 affects neurological and cognitive functions, as well as its regulatory effect on glucose metabolism. The pathophysiological relationship between GLP-1 and AD is discussed in this review. PMID- 29598934 TI - "Time Is Muscle" in Acute Heart Failure: Critical Concept or Fake News? PMID- 29598935 TI - Indications for Cardiac Resynchronization Therapy: A Comparison of the Major International Guidelines. AB - OBJECTIVES: This study compares and contrasts the recommended indications for cardiac resynchronization therapy (CRT) according to the most recent guidelines from international cardiology societies. BACKGROUND: CRT has been shown to reduce morbidity and mortality in selected patients with systolic heart failure. Cardiology societies provide guidelines regarding the indications for CRT. As evidence evolves, it is challenging for the guideline committees to review the impact of newer evidence in a timely fashion. METHODS: Six of the most recent international guidelines providing recommendation concerning CRT implantation ranging from 2011 to 2017 were reviewed. These included guidelines from 2 European, 1 North American, 1 Canadian, and 1 Australian/New Zealand societies and the National Institute for Health and Care Excellence guidelines, specific to the United Kingdom. RESULTS: Although international societies provide consistent recommendations for most CRT indications, differences are found in recommendations for several important patient populations. Specifically, divergent recommendations exist regarding QRS duration, bundle branch morphology, patients in atrial fibrillation, choice of device type (CRT pacemakers vs. CRT defibrillators), and selected patients who are likely to be dependent on right ventricular pacing. The timing of publication of specific guidelines appears to play an essential role in explaining these disparities. CONCLUSIONS: Despite general consistency in international guideline recommendations, there remain certain patient populations for whom there are variations in recommendations concerning eligibility for CRT and selection of the most appropriate device in the individual patient. PMID- 29598933 TI - The Effect of Door-to-Diuretic Time on Clinical Outcomes in Patients With Acute Heart Failure. AB - OBJECTIVES: This study sought to examine the impact of door-to-diuretic (D2D) time on mortality in patients with acute heart failure (AHF) who were presenting to an emergency department (ED). BACKGROUND: Most patients with AHF present with congestion. Early decongestion with diuretic agents could improve their clinical outcomes. METHODS: The Korea Acute Heart Failure registry enrolled 5,625 consecutive patients hospitalized for AHF. For this analysis, the study included patients who received intravenous diuretic agents within 24 h after ED arrival. Early and delayed groups were defined as D2D time <=60 min and D2D time >60 min, respectively. The primary outcomes were in-hospital death and post-discharge death at 1 month and 1 year on the basis of D2D time. RESULTS: A total of 2,761 patients met the inclusion criteria. The median D2D time was 128 min (interquartile range: 63 to 243 min), and 663 (24%) patients belonged to the early group. The baseline characteristics were similar between the groups. The rate of in-hospital death did not differ between the groups (5.0% vs. 5.1%; p > 0.999), nor did the post-discharge 1-month (4.0% vs. 3.0%; log-rank p = 0.246) and 1-year (20.6% vs. 19.3%; log-rank p = 0.458) mortality rates. Get With the Guidelines-Heart Failure risk score was calculated for each patient. In multivariate analyses with adjustment for Get With the Guidelines-Heart Failure risk score and other significant clinical covariates and propensity-matched analyses, D2D time was not associated with clinical outcomes. CONCLUSIONS: The D2D time was not associated with clinical outcomes in a large prospective cohort of patients with AHF who were presenting to an ED.

AB - INTRODUCTION: Our aim is to examine the correlation between perioperative hyperglycemia and post-operative outcomes following microvascular reconstruction of head and neck defects. PATIENTS AND METHODS: Retrospective review of a prospectively collected database of 350 consecutive patients who underwent microvascular reconstruction of malignant head and neck defects over a 2 year period. The relationship between perioperative hyperglycemia (>= 180 mg/dL) and the incidence of the following complications was evaluated: flap loss, flap related complications and surgical site infections (SSI). Sub-group analysis based on timing of hyperglycemia was also performed. RESULTS: We identified 313 patients (89.4%) in the normoglycemic group and 37 patients (10.6%) in the hyperglycemic group. Baseline demographics, tumor stage, operative variable were comparable. There were no significant differences in flap-related complications and overall mortality. SSI were significantly higher in the hyperglycemic cohort (48% vs. 28%, p = 0.01). On multivariate analysis, hyperglycemia [OR 2.07; 95% CI, 1.87-4.89], perioperative insulin administration [OR 4.805; 95% CI, 2.18 10.60], prolonged operative time [OR 1.003; 95% CI, 1.002-1.025] and higher Charlson co-morbidity indices [II: OR 2.286 & III: OR 2.284] were independent predictors of SSI. On sub-group analysis, only patients with early (POD 1) post operative hyperglycemia had a significant OR for SSI (OR 1.88; 95% CI, 1.07 3.29). CONCLUSION: Our findings suggest that perioperative hyperglycemia, specifically during the first 24 h post-operatively, is associated with SSI in microvascular head and neck reconstruction. This association highlights the need for strict screening of head and neck patients for hyperglycemia especially in the immediate post-operative period. PMID- 29598944 TI - Three-dimensional imaging assessment of anatomic invasion and volumetric considerations for chemo/radiotherapy-based laryngeal preservation in T3 larynx cancer. AB - OBJECTIVES: To investigate the impact of 3-Diminsional (3D) tumor volume (TV) and extent of involvement of primary tumor on treatment outcomes in a large uniform cohort of T3 laryngeal carcinoma patients treated with nonsurgical laryngeal preservation strategies. MATERIALS AND METHODS: The pretreatment contrast enhanced computed tomography images of 90 patients with T3 laryngeal carcinoma were reviewed. Primary gross tumor volume (GTVp) was delineated to calculate the 3D TV and define the extent of invasion. Cartilage and soft tissue involvement was coded. The extent of invasion was dichotomized into non/limited invasion versus multiple invasion extension (MIE), and was subsequently correlated with survival outcomes. RESULTS: The median TV was 6.6 cm3. Sixty-five patients had non/limited invasion, and 25 had MIE. Median follow-up for surviving patients was 52 months. The 5-year local control and overall survival rates for the whole cohort were 88% and 68%, respectively. There was no correlation between TV and survival outcomes. However, patients with non/limited invasion had better 5-year local control (LC) than those with MIE (95% vs 72%, p = .009) but did not have a significantly higher rate of overall survival (OS) (74% vs 67%, p = .327). In multivariate correlates of LC, MIE maintained statistical significance whereas baseline airway status showed a statistically significance trend with poor LC (p = .0087 and 0.06, respectively). Baseline good performance status was an independent predictor of improved OS (p = .03) in multivariate analysis. CONCLUSION: The extent of primary tumor invasion is an independent prognostic factor of LC of the disease after definitive radiotherapy in T3 larynx cancer. PMID- 29598946 TI - Cause-specific mortality in patients with head and neck cancer: Long-term follow up of a population-based cohort from 1986 to 2012 accounting for competing risks. AB - OBJECTIVES: Recent recommendations for treating head and neck cancer (HNC) patients favor an individualized approach. Expected long-term survival - together with short-term survival - after diagnosis is the primary focus in assessing the treatment modality and follow-up scheme. "Disease-specific" survival up to five years is often used for measuring the prognosis and for assessing treatment methods. However, especially long-term survival is strongly affected by competing causes of death among HNC patients. MATERIALS AND METHODS: The long-term prognosis of patients with HNC in terms of mortality from both cancer and competing causes was analyzed according to recent methodological guidelines by examining cumulative incidence functions and models for cause-specific hazards and sub-distribution hazards in a population based cohort of 220 patients treated in a tertiary care center in Northern Finland. RESULTS: In addition to well-known tumor-related factors, mortality from HNC was associated with older age. The mortality from other causes of death was strongly dependent on age and Charlson's Comorbidity Index, but less on gender. When demonstrating the importance of individualized approach in simulated patients, the mortality was highly variable across patients with similar cancer status, but with different comorbidities or age. CONCLUSION: The overall survival pattern of HNC patients depends not only on their cancer characteristics, but also varies greatly according to their age and comorbidities. Our findings support the need for individualized treatment and follow-up protocols, and active management of comorbid diseases. Appropriate methods for analyzing competing risks should be used when presenting survival estimates of cancer patients. PMID- 29598947 TI - Locoregional extension and patterns of failure for nasopharyngeal carcinoma with intracranial extension. AB - OBJECTIVE: To evaluate the locoregional extension and patterns of failure for nasopharyngeal carcinoma (NPC) with intracranial extension to improve clinical target volume (CTV) delineation. PATIENTS AND METHODS: A total of 205 NPC patients with intracranial extension by magnetic resonance imaging (MRI) were retrospectively reviewed. RESULTS: According to the cumulative incidence rates of tumor invasion, we initially classified anatomic sites surrounding the nasopharynx into three risk grades: high risk (>=35%), medium risk (>=10-35%), and low risk (<10%). It was concluded that the anatomic sites at high risk of tumor invasion were the middle/posterior skull base and the anatomic sites adjacent to the nasopharynx. The rate of lymph node (LN) metastasis was 90.2% (185/205). Retropharyngeal region (RP) and level IIb were the most frequently involved regions. Skip metastasis occurred in only 1.6% (3/185). At their last follow-up visit, 53 patients (25.9%) had developed treatment failure. Of the 18 local failures, 12 were considered in-field failure; the other 5 were marginal; one of the patients had outside-field failure. Among the 5 patients with marginal failures, 4 occurred mainly intracranially, and 1 occurred in the floor and the left lateral wall of the nasopharynx. Of the 11 regional failures, 10 were considered in-field failures and most of them (8/10) occurred in the unilateral upper neck. CONCLUSION: For NPC with intracranial extension, primary disease and regional LN spread follow an orderly pattern and LN skipping was unusual. Clinical target volume reduction may be feasible for selected patients. PMID- 29598948 TI - The impact of HPV status on weight loss and feeding tube use in oropharyngeal carcinoma. AB - OBJECTIVES: It has been well established that patients with oropharyngeal carcinoma are at high nutritional risk, with significant weight loss and tube feeding common. Human papillomavirus (HPV)-associated disease has led to a change in the "typical" presentation and nutritional profile of this population. The aim of our study was to determine whether the need for a feeding tube, and weight loss during radiotherapy (RT) in patients with oropharyngeal carcinoma differed with HPV status. MATERIALS AND METHODS: Patients who received curative RT +/- chemotherapy from January 2011 to January 2016 were included (n = 100). We retrospectively evaluated feeding tube use and timing of insertion (prophylactic vs reactive), percentage weight loss during RT and the prevalence of critical weight loss (CWL) >=5%. RESULTS: HPV-positive patients had significantly higher weight loss during RT compared to the rest of the cohort (8.4% vs 6.1%, 95%CI 0.8 3.9, p = 0.003). CWL was observed in 86% and in a higher proportion with HPV positive disease (93%, p = 0.011). Conditional probability modelling analysis revealed, with 74% accuracy, concurrent chemoradiotherapy and HPV-positive status were predictors of CWL when comparing HPV-positive patients to HPV-negative (96%, p = 0.001 and 98%, p = 0.012 respectively). More HPV-positive patients required feeding tubes (n = 43, 63%, p = 0.05), most being reactive (n = 27, 63%). All patients with reactive tubes experienced CWL. CONCLUSION: The high incidence of CWL in patients with HPV-positive oropharyngeal carcinoma is of concern. Tube feeding continues to be a necessary nutritional intervention in this population and predicting who will require a tube is challenging. Larger, prospective cohort studies are required. PMID- 29598949 TI - Optimizing the induction chemotherapy regimen for patients with locoregionally advanced nasopharyngeal Carcinoma: A big-data intelligence platform-based analysis. AB - OBJECTIVES: This study aimed at identifying the optimal induction chemotherapy regimen for patients with locoregionally advanced nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy. MATERIALS AND METHODS: We identified eligible patients with newly-diagnosed stage III-IVA NPC (excluding T3N0) between September 2009 and May 2015. Survival outcomes and grade 3-4 toxicities were compared between different IC regimen groups. RESULTS: In total, 3738 patients were eligible for this study, with 1572 (42.1%), 1085 (29.0%) and 1081 (28.9%) receiving TPF, PF and TP, respectively. In the whole population, multivariate analysis found that TPF seems to be better than PF and TP. Howerver, subgroup analysis revealed TPF and TP had same effectiveness in patients receiving a cumulative cisplatin dose (CCD) >=200mg/m2 in concurrent chemotherapy, while TPF shows relatively better survival benefit in patients receiving CCD<200mg/m2. Grade 3-4 toxicities were similar between TPF and TP groups, but were relatively higher than that in PF group. CONCLUSIONS: Our study concluded that induction TP regimen may be enough for patients receiving a CCD>=200mg/m2, while TPF may be superior to TP and PF for patients receiving a CCD<200mg/m2, although grade 3-4 toxic events were more common but tolerable. Further studies are needed to validate our findings. PMID- 29598950 TI - Tumor volume as a predictor of survival in T3 glottic carcinoma: A novel approach to patient selection. AB - BACKGROUND: The optimal treatment for T3 glottic cancers continues to be debated. Organ preservation has become the standard of care, but not all tumors respond equally. The purpose of this was to investigate the long-term survival outcomes of organ preservation protocols based on tumor volume. METHODS: A retrospective review of prospectively collected data from 1966 to 2016 was performed. Patients with T3 vocal cord cancer treated with radiation therapy (RT) at the University of Florida were included. Local control rates as well as survival rates were determined with a Kaplan Meier and Cox regression analysis. Survival was analyzed as a function of tumor volume and an optimal cut point was determined. RESULTS: 107/234 patients were included. 79% received RT and 21% chemo-RT. 5-year local control was 61.5% and 5-year disease specific survival was 79.3%. Tumor volume was a significant predictor of survival (p = 0.007). An optimal cut point for tumor volume was 2.5 cc. Patients with tumor volumes >=2.5 cc had significantly worse (p < 0.05) tumor control rates (100% vs. 70.4%). CONCLUSION: Tumor volume is a significant predictor of survival outcomes in T3 vocal cord cancers, but will need external validation. Tumors <2.5 cc have favorable outcomes. Those with higher volume tumors should be counselled appropriately and be considered for primary surgical management. PMID- 29598951 TI - Overexpression of PIK3CA in head and neck squamous cell carcinoma is associated with poor outcome and activation of the YAP pathway. AB - OBJECTIVES: Phosphatidylinositol 3-kinase catalytic subunit alpha (PIK3CA) is commonly altered in many human tumors, leading to the activation of p110alpha enzymatic activity that stimulates growth factor-independent cell growth. PIK3CA alterations such as mutation, gene amplification and overexpression are common in head and neck squamous cell carcinoma (HNSCC) and. We aim to explore how these alterations and clinical outcome are associated, as well as the molecular mechanisms involved. MATERIAL AND METHODS: Mutation and copy-number variation in PIK3CA, and whole-genome expression profiles, were analyzed in primary HNSCC tumors from The Cancer Genome Atlas (TCGA) cohort (n = 243). The results were validated in an independent cohort form the University Hospital of A Coruna (UHAC, n = 62). Expression of the PIK3CA gene protein product (PI3K p110alpha) and nuclear YAP were assessed in tissue microarrays in a cohort from the University Hospital 12 de Octubre (UH12O, n = 91). RESULTS: Only high expression of the PIK3CA gene was associated with poor clinical outcome. The study of gene expression, transcription factor and protein signatures suggested that the activation of the Hippo-YAP pathway, involved in organ size, stem cell maintenance and tumorigenesis, could underlie tumor progression in PI3KCA overexpressing tumors. Tissue arrays showed that PI3K p110alpha levels correlated with YAP nuclear localization in HNSCC tumors. CONCLUSIONS: High expression of PIK3CA in HNSCC primary tumors identifies patients at high risk for recurrence. In these tumors, progression could rely on the Hippo-YAP pathway instead of the canonical Akt/mTOR pathway. This observation could have important implications in the therapeutic options for patients. PMID- 29598952 TI - Upfront surgery versus definitive chemoradiotherapy in patients with human Papillomavirus-associated oropharyngeal squamous cell cancer. AB - OBJECTIVES: Currently, human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV-A OPC) is managed with either primary surgery or definitive chemoradiotherapy (CRT), despite the lack of supporting randomized prospective data. We therefore assessed the outcomes of each treatment strategy using the National Cancer Database (NCDB). METHODS: The NCDB was used to identify patients diagnosed with cT1 N2a-2b or cT2 N1-2b HPV-A OPC from 2010 to 2013 who underwent treatment with primary surgery or CRT. Demographic and clinicopathologic predictors of treatment were analyzed by the chi-square test and logistic regression. Overall survival (OS) was evaluated using multivariable Cox proportional hazard regression, Kaplan-Meier, log-rank test, and propensity score matched analysis. RESULTS: We identified 3063 patients; 1576 (51.5%) received CRT and 1487 (48.5%) underwent primary surgery. Median follow up was 32 months. 972 (65.4%) surgical patients received adjuvant CRT. On multivariable Cox regression, 3-year OS was comparable between surgery and CRT (hazard ratio [HR] 1.08, 95% confidence interval [CI] 0.83-1.41, P = 0.58). Inferior OS was significantly associated with increasing clinical T and N stage, older age, and non-private insurance. Propensity score-matching yielded a 2526 patient cohort and redemonstrated similar OS (HR, 1.09; 95% CI 0.81-1.47; P = 0.55). Comparable outcomes persisted in a subset analysis of patients with margin-negative resection, with 3-year OS 90.8% in CRT patients vs. 93.6% in surgery patients (log-rank P = 0.27). CONCLUSIONS: Upfront surgery and CRT yielded comparable 3 year OS outcomes in this cohort. In this national sample, 65.4% of surgical patients received trimodal therapy with adjuvant CRT, highlighting the need for improved patient selection for primary surgery.

AB - OBJECTIVES: To evaluate the therapeutic results and rate of organ preservation in patients with squamous cell carcinoma of the tongue treated with retrograde superselective intra-arterial chemoradiotherapy. MATERIALS AND METHODS: Between June 2006 and June 2015, 118 patients with tongue cancer were treated with intra arterial chemoradiotherapy. Treatment consisted of radiotherapy (total 50-70 Gy) and daily concurrent intra-arterial chemotherapy (docetaxel, total 50-70 mg/m2; cisplatin, total 125-175 mg/m2) for 5-7 weeks. Locoregional control and overall survival rates were calculated by the Kaplan-Meier method. Cox's proportional hazards model was used for both univariate and multivariate analyses. RESULTS: The median follow-up for all patients was 38.5 months (range, 3-129 months). After intra-arterial chemoradiotherapy, primary site complete response was achieved in 113 (95.8%) of 118 cases. Three-year locoregional control and overall survival rates were 80.3% and 81.5%, respectively. Grade 3 or 4 toxicities included neutropenia in 16.1% and mucositis in 87.3%. Grade 3 toxicities included anemia in 12.7%, thrombocytopenia in 3.4%, nausea/vomiting in 3.4%, dermatitis in 45.7%, dysphagia in 74.6%, and fever in 2.5% of patients. Late toxicity consisting of grade 3 osteoradionecrosis of the jaw occurred in 4.2% of patients. On univariate analysis, T stage and overall stage were significantly associated with locoregional control, and N stage and overall stage were significantly associated with overall survival. On multivariate analysis, the only significant predictor of overall survival was overall stage classification. CONCLUSION: Retrograde superselective intra-arterial chemoradiotherapy for tongue cancer provided good overall survival and locoregional control.

AB - OBJECTIVES: Randomized trials evaluating cisplatin versus cetuximab chemoradiation (CRT) for p16+ oropharyngeal cancer (OPC) have yet to report preliminary data. Meanwhile, as a preemptive step toward morbidity reduction, the off-trial use of cetuximab in p16+ patients is increasing, even in those who could potentially tolerate cisplatin. The purpose of this study was to compare the efficacy of cisplatin versus cetuximab CRT in the treatment of p16+ OPC and to identify prognostic factors and predictors of tumor response. MATERIALS AND METHODS: Cases of p16+ OPC treated with cisplatin or cetuximab CRT at our institution from 2010 to 2014 were identified. Recursive partitioning analysis (RPA) classification was used to determine low-risk (LR-RPA) and intermediate risk (IR-RPA) groups. Log-rank/Kaplan-Meier and Cox Regression methods were used to compare groups. RESULTS: We identified 205 patients who received cisplatin (n = 137) or cetuximab (n = 68) CRT in the definitive (n = 178) or postoperative (n = 27) setting. Median follow-up was 3 years. Cisplatin improved 3-year locoregional control (LRC) [92.7 vs 65.4%], distant metastasis-free survival (DMFS) [88.3 vs 71.2%], recurrence-free survival (RFS) [86.6 vs 50.6%], and overall survival (OS) [92.6 vs 72.2%] compared to cetuximab [all p < .001]. Concurrent cisplatin improved 3-year OS for LR-RPA (97.1 vs 80.3%, p < .001) and IR-RPA (97.1 vs 80.3%, p < .001) groupings. CONCLUSION: When treating p16+ OPC with CRT, the threshold for substitution of cisplatin with cetuximab should be maintained appropriately high in order to prolong survival times and optimize locoregional and distant tumor control. When cetuximab is used in cisplatin ineligible patients, altered fractionation RT should be considered in an effort to improve LRC. PMID- 29598955 TI - Prognostic Impact of Weight Change During Adjuvant Chemotherapy in Patients With High-Risk Early Breast Cancer: Results From the ADEBAR Study. AB - BACKGROUND: In addition to established prognostic factors, individual lifestyle associated factors, such as obesity, physical activity, and diet, seem to modulate the course of breast cancer. The aim of this analysis was to evaluate the influence of weight changes during adjuvant chemotherapy on outcome in a large multicenter prospectively randomized trial. PATIENTS AND METHODS: The ADEBAR trial compares a sequential chemotherapy consisting of epirubicin/cyclophosphamide followed by docetaxel to an epirubicin/5 fluorouracil/cyclophosphamide regimen in patients with lymph node-positive early breast cancer. Body weight was measured before each cycle of chemotherapy. According to the relative weight change (>= 5%) between the first and the last cycle, patients were categorized into the weight gain, weight loss, or stable weight group. Overall survival (OS) and disease-free survival were assessed by univariate Kaplan-Meier and multivariate Cox regression analyses. RESULTS: Concise data from 1080 of 1493 participants who completed all cycles of chemotherapy were available for analysis. Of 307 patients (24.8%) whose weight changed by >= 5%, 120 patients (11.1%) lost and 187 (17.3%) gained weight. Multivariate analysis showed a significant independent effect of weight change on OS (P = .039), but not on disease-free survival (P = .111). Both weight change groups had a worse OS compared to patients with stable weight (weight gain: hazard ratio, 1.55; 95% confidence interval, 1.01-2.40; P = .047; weight loss: hazard ratio, 1.55; 95% CI, 0.97-2.47; P = .067). CONCLUSION: Weight change of > 5% during adjuvant chemotherapy in patients with high-risk early breast cancer is associated with poor OS.

AB - This paper explores a two-level control strategy by blending local controller with centralized controller for the low frequency oscillations in a power system. The proposed control scheme provides stabilization of local modes using a local controller and minimizes the effect of inter-connection of sub-systems performance through a centralized control. For designing the local controllers in the form of proportional-integral power system stabilizer (PI-PSS), a simple and straight forward frequency domain direct synthesis method is considered that works on use of a suitable reference model which is based on the desired requirements. Several examples both on one machine infinite bus and multi-machine systems taken from the literature are illustrated to show the efficacy of the proposed PI-PSS. The effective damping of the systems is found to be increased remarkably which is reflected in the time-responses; even unstable operation has been stabilized with improved damping after applying the proposed controller. The proposed controllers give remarkable improvement in damping the oscillations in all the illustrations considered here and as for example, the value of damping factor has been increased from 0.0217 to 0.666 in Example 1. The simulation results obtained by the proposed control strategy are favourably compared with some controllers prevalent in the literature. PMID- 29598957 TI - Pharmacovigilance in pediatrics. AB - The characteristics of pharmacology and drug evaluation in the pediatric age group highlight the necessity for the pharmacovigilance community to adjust to the specific features of children. At the time of marketing a medicinal product intended for children, the product's safety profile is sometimes less well known than for adults due to fewer or small sample clinical trials. Furthermore, the frequent off-labeled drug use, the use of unsuitable dosage forms and the need for continuous dose adjustments increase the risk of medication errors and thus lead to avoidable adverse drug reactions (ADRs). The occurrence of child-specific ADRs (such as growth disorders) or ADRs more commonly occurring in children than in adults make it necessary to monitor the safety of child-specific drugs. Pediatric pharmacovigilance includes also the consequences of in utero exposure, whether manifestations are present from birth or occur in early childhood (such as neurodevelopmental disorders). The incidence of ADRs varies with age, setting of medical care (in- or out-patients, pediatric specialties) and by country in which the study was carried out. The drugs most frequently reported with ADRs are those most commonly used in the pediatric age group, i.e. antibiotics and vaccines. The ADRs most often reported are skin, neurological and general disorders. As in adults, spontaneous notification is essential to generate alerts and child-specific pharmacoepidemiological studies are necessary and should be developed.

AB - OBJECTIVES: The main objective of the study is to perform an analysis on the incidence, predictive variables, and severity of acute kidney injury (AKI) and its impact on the morbidity and mortality of patients in the Resuscitation and Special Care Unit (RSCU) of a regional hospital. METHODS: A retrospective observational study was conducted that included all patients admitted from 1 January 2012 to 1 January 2015 (1,115 patients). The follow-up was until 15 July 2015. A descriptive statistical analysis of clinical-epidemiological and analytical variables was carried out. An analysis was then performed AKI in RSCU and mortality, as well as the agreement between the RIFLE (Risk, Injury, Failure, Loss of Kidney Function, and End-stage Kidney Disease)/AKIN (Acute Kidney Injury Network)/KDIGO (Kidney Disease: Improving Global Outcomes) criteria (kappa index). A multivariate logistic regression analysis was performed to select the variables associated with the presentation of AKI in RSCU and a univariate (Kaplan-Meier) and multivariate survival analysis (Cox regression). The statistical analysis was carried out using the statistical package SPSS 21. RESULTS: During admission to RSCU, 486 patients presented with AKI (43.6%), of which 21% were in stage I, 13.8% in stage II, and in stage III 8.7%. A high level of agreement was observed between the RIFLE/AKIN/KDIGO criteria. The variables that were related to the presence of AKI, are male (OR: 1.37; 95% CI: 1.02-2.30), to high Charlson comorbidity index (OR: 1.17; 95% CI: 1.09-1.26), carriers of chronic kidney disease (OR: 5.99; 95% CI: 4.58-8.18), admission due to surgery (OR: 1.69; 95% CI: 1.24-2.30), and shock (OR: 4.70; 95% CI: 3.34-6.61). The probability of survival during admission in RSCU decreases in patients with AKI (HR: 5.44; 95% CI: 1.70-17.39), and as the individual severity index of Liano increases (HR: 10.29; 95% CI: 3.34-31.76). The probability of survival at the end of follow-up after hospital discharge decreases in patients with AKI (HR: 1.72; 95% CI: 1.14-2.61), as the individual severity index of Liano increases (HR: 9,6; 95% CI: 5.07-18.20), the Charlson comorbidity index>6 (HR: 1.09; 95% CI: 1.03 1.15), low serum albumin<2.5mg/dL (HR: 1.69; 95% CI: 1.13-2.53), age by year>70 years (HR: 1.03; 95% CI: 1.01-1.04), males (HR: 1.38; 95% CI: 1.06-1.79) and carriers of previous chronic kidney disease (HR: 1.56; 95% CI: 1.02-2.38). CONCLUSIONS: This study shows the presentation of an episode of AKI was an independent factor associated both with mortality during admission to RSCU, and later after hospital discharge. It is necessary to know the risk factors of this complication in order to adopt preventive measures. PMID- 29598960 TI - Older people living with chronic illness. AB - This study aimed to gain a better understanding of what it is like for older people to live with chronic illness. A Phenomenological method was used. A purposive sampling strategy was used to recruit older people with chronic illness from one community in Nakhonratchasima province, Thailand. Semi-structured interview guides were used to explore the participants' experiences and perceptions. Data saturation was reached after 30 interviews were completed. The data was analyzed using thematic analysis. Four themes emerged from the data: 1) living a restricted life, 2) feeling overwhelmed, 3) understanding and accepting loss, and 4) being kind to oneself and learning to live with the disease. The findings may increase understanding about what older people with chronic illness experience. Health care providers can use this understanding to relate health care and guidance to their patients by incorporating cultural influences and religious/spiritual beliefs into the standardized care for this population. PMID- 29598961 TI - 20-MHz Ultrasound for Measurements of Flow-Mediated Dilation and Shear Rate in the Radial Artery. AB - A high-frequency scanning system consisting of a 20-MHz linear array transducer combined with a 20-MHz pulsed Doppler probe was introduced to evaluate the degree of radial artery flow-mediated dilation (FMD [%]) in two groups of patients after 5 min of controlled forearm ischemia followed by reactive hyperemia. In group I, comprising 27 healthy volunteers, FMD (mean +/- standard deviation) was 15.26 +/- 4.90% (95% confidence interval [CI]: 13.32%-17.20%); in group II, comprising 17 patients with chronic coronary artery disease, FMD was significantly less at 4.53 +/- 4.11% (95% CI: 2.42%-6.64%). Specifically, the ratio FMD/SR (mean +/- standard deviation), was equal to 5.36 * 10-4 +/- 4.64 * 10-4 (95% CI: 3.54 * 10 4 to 7.18 * 10-4) in group I and 1.38 * 10-4 +/- 0.89 * 10-4 (95% CI: 0.70 * 10-4 to 2.06 * 10-4) in group II. Statistically significant differences between the two groups were confirmed by a Wilcoxon-Mann-Whitney test for both FMD and FMD/SR (p <0.01). Areas under receiver operating characteristic curves for FMD and FMD/SR were greater than 0.9. The results confirm the usefulness of the proposed measurements of radial artery FMD and SR in differentiation of normal patients from those with chronic coronary artery disease.

AB - Lung ultrasound (LUS) is a largely employed diagnostic tool but an operational protocol for implementation has never been proposed. The lack of standardization clearly introduces variability in LUS results. We enrolled adult patients presenting for acute dyspnea with a clinical suspect of etiology related to heart failure. We calculated agreement among four providers in assessing B-lines. We varied probes, depth, evaluation time and scanning areas and we estimated the importance of each factors on B-lines assessment. Overall agreement among raters varied from a kappa of 0.70 to 0.81. The mean number of B-lines was 5.44 (95% confidence interval, CI, 4.1-6.8). This estimate did not suffer variation by the depth used (0.03, 95% CI -0.2-0.2, more B-lines, using 19 cm versus 10 cm). The use of a convex probe and expertise in LUS reduced the number of artifacts by 1.7 (95% CI 1.5-1.9) and 1.1 in comparison with a phased array probe and naive operators. Evaluation time increased estimates by 1.2 (95% CI 1-1.5) and 2.9 (95% CI 2.7-3.9) B-lines for 4" and 7" clips (reference was 2" clips). This study suggests that the probe, the evaluation time and the level of expertise might affect the results of quantitative assessment of B-lines. PMID- 29598964 TI - Patient feedback questionnaires to enhance consultation skills of healthcare professionals: A systematic review. AB - OBJECTIVE: To identify patient feedback questionnaires that assess the development of consultation skills (CSs) of practitioners. METHODS: We conducted a systematic search using seven databases from inception to January 2017 to identify self-completed patient feedback questionnaires assessing and enhancing the development of CSs of individual practitioners. Results were checked for eligibility by three authors, and disagreements were resolved by discussion. Reference lists of relevant studies and Open Grey were searched for additional studies. RESULTS: Of 16,312 studies retrieved, sixteen were included, describing twelve patient feedback questionnaires that were mostly designed for physicians in primary care settings. Most questionnaires had limited data regarding their psychometric properties, except for the Doctor Interpersonal Skills Questionnaire (DISQ). Most studies conducted follow-up, capturing positive views of practitioners regarding the process (n = 14). Feedback was repeated by only three studies, demonstrating different levels of improvement in practitioners' performance. CONCLUSION: Identified questionnaires were mainly focused on physicians, however, to support using patient feedback, questionnaires need to be validated with other practitioners. PRACTICE IMPLICATIONS: Several patient feedback questionnaires are available, showing potential for supporting practitioners' development. Valid questionnaires should be used with appropriate practitioners in developing more evidence for the impact they may have on actual consultations. PMID- 29598965 TI - Validation of the health literacy scale for diabetes as a criterion-referenced test with standard setting procedures. AB - OBJECTIVE: To develop and examine the psychometric properties of the Korean Health Literacy Scale for Diabetes Mellitus (KHLS-DM), and to establish reasonable cutoff scores. METHODS: Initially, 299 items were generated to measure diabetes-related words, numeracy, and information utilization. Content validity assessment and preliminary tests were conducted. After exploratory factor analysis (EFA) and Rasch analysis, the remaining 65 items were administered to a quota sample of 500 diabetic patients aged 40-74 years. The items were narrowed down to 58 items based on an item fit index. To obtain cutoff scores, Jaeger's method and the Bookmark method were employed. RESULTS: A confirmatory factor analysis (CFA) was performed, and a three-factor model was supported (chi2/df = 3.891, CFI = 0.92, TLI = 0.91, RMSEA = 0.04). The overall scores ranged from 0 to 58, and two cutoff points were established. The scale exhibited good internal consistency (Cronbach's alpha = 0.83). CONCLUSIONS: The KHLS-DM is a reliable and valid measure with cutoff points to classify individuals into three groups (adequate, marginal, and inadequate). PRACTICE IMPLICATIONS: The standard setting may be useful for researchers to validate health literacy measures in other countries and populations.

PMID- 29598967 TI - Surveillance of sexualised drug use - the challenges and the opportunities. AB - Sexualised drug use (SDU), the use of drugs in a sexual context, has emerged as a marker of high-risk sexual activity and poor sexual health among gay, bisexual and other men who have sex with men, however, there are no robust estimates of the prevalence of SDU. The primary sources of surveillance data on SDU should include both sexual health and drug treatment services. The challenges to achieving comprehensive, timely and valid SDU surveillance include establishing case definitions, selecting appropriate surveillance settings, and normalising the monitoring of SDU at clinical services. In this commentary we propose a means to address these challenges and discuss other sources of SDU data from ad hoc population surveys and sentinel systems. We also present case studies of SDU surveillance development in England and Switzerland. The patterns of SDU will be affected by a rapidly changing drug market and, as a result, surveillance systems must continuously adapt to ensure that they are fit for purpose and can provide data to guide policy.

AB - The dramatic increase in life expectancy is leading to a significant increase in the use of gastrointestinal endoscopy in the elderly. Taking into account these demographic changes, the use of gastrointestinal endoscopy in this age group is of great importance. Although these procedures are generally safe and well tolerated even in very elderly patients, the onset of physiological changes associated with aging and the increased prevalence of cardiovascular and pulmonary comorbidities raise the risk of sedation related complications in these patients. Age alone is not a contraindication for performing any endoscopic procedure. However, elderly patients have their own peculiarities that require a detailed review of the characteristics, risks and benefits of endoscopic procedures in this specific context.

AB - BACKGROUND: Candida albicans is the most important fungal pathogen that causes infections in humans, and the search for new therapeutic strategies for its treatment is essential. OBJECTIVE: The aim of this study was to evaluate the activity of seven naphthoquinones (beta-lapachone, beta-nor-lapachone, bromide beta-lapachone, hydroxy-beta-lapachone, alpha-lapachone, alpha-nor-lapachone and alpha-xyloidone) on the growth of a fluconazole-resistant C. albicans oral clinical isolate and the effects of these compounds on the viability of mammalian cells, on yeast's morphogenesis, biofilm formation and cell wall mannoproteins availability. RESULTS: All the compounds were able to completely inhibit the yeast growth. beta-lapachone and alpha-nor-lapachone were the less cytotoxic compounds against L929 and RAW 264.7 cells. At IC50, beta-lapachone inhibited morphogenesis in 92%, while the treatment of yeast cells with alpha-nor-lapachone decreased yeast-to-hyphae transition in 42%. At 50MUg/ml, beta-lapachone inhibited biofilm formation by 84%, whereas alpha-nor-lapachone reduced biofilm formation by 64%. The treatment of yeast cells with beta-lapachone decreased cell wall mannoproteins availability in 28.5%, while alpha-nor-lapachone was not able to interfere on this virulence factor. Taken together, data show that beta lapachone and alpha-nor-lapachone exhibited in vitro cytotoxicity against a fluconazole-resistant C. albicans strain, thus demonstrating to be promising candidates to be used in the treatment of infections caused by this fungus. PMID- 29598975 TI - Use of modified Richards model to predict isothermal and non-isothermal microbial growth. AB - Mathematical models are often used to predict microbial growth in food products. An important class of these models involves the adaptation of classical sigmoid functions, such as the Gompertz and logistic functions. This study aimed to validate the use of the modified Richards model in various situations, which have not previously been tested. The model was obtained through solving a system of two differential equations and could be applied to both isothermal and non isothermal environments. To test and validate this model, we used published datasets containing data for the growth of Pseudomonas spp. in fish products. The results obtained after fitting the model showed that it could be effectively used to describe and predict the Pseudomonas growth curves under various temperature regimens. However, the influence of the shape parameter on the growth curve is an issue that needs further evaluation. PMID- 29598976 TI - Phylogenetic MLSA and phenotypic analysis identification of three probable novel Pseudomonas species isolated on King George Island, South Shetland, Antarctica. AB - Antarctica harbors a great diversity of microorganisms, including bacteria, archaea, microalgae and yeasts. The Pseudomonas genus is one of the most diverse and successful bacterial groups described to date, but only eight species isolated from Antarctica have been characterized. Here, we present three potentially novel species isolated on King George Island. The most abundant isolates from four different environments, were genotypically and phenotypically characterized. Multilocus sequence analysis and 16S rRNA gene analysis of a sequence concatenate for six genes (16S, aroE, glnS, gyrB, ileS and rpoD), determined one of the isolates to be a new Pseudomonas mandelii strain, while the other three are good candidates for new Pseudomonas species. Additionally, genotype analyses showed the three candidates to be part of a new subgroup within the Pseudomonas fluorescens complex, together with the Antarctic species Pseudomonas antarctica and Pseudomonas extremaustralis. We propose terming this new subgroup P. antarctica. Likewise, phenotypic analyses using API 20 NE and BIOLOG(r) corroborated the genotyping results, confirming that all presented isolates form part of the P. fluorescens complex. Pseudomonas genus research on the Antarctic continent is in its infancy. To understand these microorganisms' role in this extreme environment, the characterization and description of new species is vital. PMID- 29598977 TI - "You Aren't Going to Cut On Me!"

AB - : The aim of the study was to compare three methods for high-score measurement in children, Caton-Deschamps, Blackburne-Peel and Koshino-Sugimoto, to determine the normal value of each method in a group of normal children. MATERIALS AND METHODS: A cross-sectional study on knee x-rays of normal children. Three orthopaedic surgeons measured the Caton-Deschamps, Blackburne-Peel and Koshino-Sugimoto indices. Concordance was assessed using the intraclass correlation coefficient. For interobserver variability, the measurements of each observer for each index were compared and for intraobserver variability, the coefficient between the 2 measurements was calculated by the same observer at 2 different times. RESULTS: 140 knee X-rays divided into 4 age groups were obtained. For the Blackburne-Peel index, an average median of the 3 observers was obtained of 1.07 and with P5-P95 (0.76-1.60). For the Caton-Deschamps index, an average median of the three observers of 1.22 was obtained and with P5-P95 (0.91-1.70). For the Koshino Sugimoto index, we obtained an average median of the 3 observers of 1.16 and with P5-P95 (0.99-1.36). DISCUSSION: This study shows that the Koshino-Sugimoto index had the highest reliability, reproducibility and similarity in the population studied, both intra-observer and inter-observer. The other methods evaluated also had variability indices to be taken into account, but were inferior to the Koshino-Sugimoto index.

AB - CONTEXT: Despite support for active surveillance (AS) as a first treatment choice for men with low-risk prostate cancer (PC), this strategy is largely underutilised. OBJECTIVE: To systematically review barriers and facilitators to selecting and adhering to AS for low-risk PC. EVIDENCE ACQUISITION: We searched PsychINFO, PubMed, Medline 2000-now, Embase, CINAHL, and Cochrane Central databases between 2002 and 2017 using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. The Purpose, Respondents, Explanation, Findings and Significance (PREFS) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) quality criteria were applied. Forty-seven studies were identified. EVIDENCE SYNTHESIS: Key themes emerged as factors influencing both choice and adherence to AS: (1) patient and tumour factors (age, comorbidities, knowledge, education, socioeconomic status, family history, grade, tumour volume, and fear of progression/side effects); (2) family and social support; (3) provider (speciality, communication, and attitudes); (4) healthcare organisation (geography and type of practice); and (5) health policy (guidelines, year, and awareness). CONCLUSIONS: Many factors influence men's choice and adherence to AS on multiple levels. It is important to learn from the experience of other chronic health conditions as well as from institutions/countries that are making significant headway in appropriately recruiting men to AS protocols, through standardised patient information, clinician education, and nationally agreed guidelines, to ultimately decrease heterogeneity in AS practice. PATIENT SUMMARY: We reviewed the scientific literature for factors affecting men's choice and adherence to active surveillance (AS) for low-risk prostate cancer. Our findings suggest that the use of AS could be increased by addressing a variety of factors such as information, psychosocial support, clinician education, and standardised guidelines.

AB - BACKGROUND: Rhythmical massage therapy (RMT) is a massage technique used in anthroposophic medicine. OBJECTIVE: The authors aimed to investigate the physiological action of RMT on the cardiovascular system by analysing heart rate variability (HRV). DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This study was a randomised, controlled and single-blinded trial, involving 44 healthy women (mean age: (26.20 +/- 4.71) years). The subjects were randomised to one of three arms: RMT with aromatic oil (RA), RMT without aromatic oil (RM) or standardised sham massage (SM). In the study the subjects were exposed to a standardised stress situation followed by one of the study techniques and Holter electrocardiograms (ECGs) were recorded for 24 h. MAIN OUTCOME MEASURES: HRV parameters were calculated from linear (time and frequency domain) and nonlinear dynamics (symbolic dynamics, Poincare plot analysis) of the 24-h Holter ECG records. RESULTS: Short- and long-term effects of massage on autonomic regulation differed significantly among the three groups. Immediately after an RMT session, stimulation of HRV was found in the groups RA and RM. The use of an aromatic oil produced greater short-term measurable changes in HRV compared with rhythmic massage alone, but after 24 h the effect was no longer distinguishable from the RM group. The lowest stimulation of HRV parameters was measured in the SM group. CONCLUSION: RMT causes specific and marked stimulation of the autonomic nervous system. Use of a medicinal aromatic oil had only a temporary effect on HRV, indicating that the RM causes the most relevant long-term effect. The effect is relatively specific, as the physiological effects seen in the group of subjects who received only SM were considerably less pronounced.

A key assumption of self management interventions is that enhancing people's self-efficacy (e.g., via the development of relevant skills and behaviours) encourages adaptive health-related behaviors and improved health outcomes. However, the group-based nature of the programs allows for the possibility that identification with other program members is itself a social psychological platform for positive changes in illness related confidence (i.e., group-derived efficacy) and physical and mental health. METHOD: The researchers evaluated this hypothesis in a telehealth version of a chronic disease self-management program delivered in 13 rural and remote communities in northern Ontario, Canada (September 2007 to June 2008). Participants were 213 individuals with a self-reported physician diagnosis of chronic lung disease, heart disease, stroke, or arthritis. Measures of social identification, group-derived efficacy, and individual efficacy were administered seven weeks after baseline, and mental and physical health outcomes (health distress, psychological well-being, depression, vitality, pain, role limits, and disability) were assessed at four months. RESULTS: Structural equation modeling indicated that social identification was a positive predictor of group-derived efficacy and (in turn) individual self-efficacy (controlling for baseline), which was significantly associated with better physical and mental health outcomes. CONCLUSION: The results are consistent with growing evidence of the value of a social identity-based approach in various health and clinical settings. The success of chronic disease self-management programs could be enhanced by attending to and augmenting group identification during and after the program.

AB - Assessment of ocular irritation potential is an international regulatory requirement in the safety evaluation of industrial and consumer products. None in vitro ocular irritation assays are capable of fully categorizing chemicals as stand-alone. Therefore, the CEFIC-LRI-AIMT6-VITO CON4EI consortium assessed the reliability of eight in vitro test methods and computational models as well as established a tiered-testing strategy. One of the selected assays was Bovine Corneal Opacity and Permeability (BCOP). In this project, the same corneas were used for measurement of opacity using the OP-KIT, the Laser Light-Based Opacitometer (LLBO) and for histopathological analysis. The results show that the accuracy of the BCOP OP-KIT in identifying Cat 1 chemicals was 73.8% while the accuracy was 86.3% for No Cat chemicals. BCOP OP-KIT false negative results were often related to an in vivo classification driven by conjunctival effects only. For the BCOP LLBO, the accuracy in identifying Cat 1 chemicals was 74.4% versus 88.8% for No Cat chemicals. The BCOP LLBO seems very promising for the identification of No Cat liquids but less so for the identification of solids. Histopathology as an additional endpoint to the BCOP test method does not reduce the false negative rate substantially for in vivo Cat 1 chemicals. PMID- 29598996 TI - Reprint of "CON4EI: Selection of the reference chemicals for hazard identification and labelling of eye irritating chemicals". AB - Assessment of the acute eye irritation potential is part of the international regulatory requirements for testing of chemicals. In the past, several prospective and retrospective validation studies have taken place in the area of serious eye damage/eye irritation testing. Success in terms of complete replacement of the regulatory in vivo Draize rabbit eye test has not yet been achieved. A very important aspect to ensure development of successful alternative test methods and/or strategies for serious eye damage/eye irritation testing is the selection of appropriate reference chemicals. A set of 80 reference chemicals was selected for the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project, in collaboration with Cosmetics Europe, from the Draize Reference Database published by Cosmetics Europe based on key criteria that were set in their paper (e.g. balanced by important driver of classification and physical state). The most important goals of the CON4EI project were to identify the performance of eight in vitro alternative tests in terms of driver of classification and to identify similarities/differences between the methods in order the build a successful testing strategy that can discriminate between all UN GHS categories. This paper provides background on selection of the test chemicals. PMID- 29598997 TI - Unravelling the adaptation strategies employed by Glaciozyma antarctica PI12 on Antarctic sea ice. AB - Glaciozyma antarctica PI12, is a psychrophilic yeast isolated from Antarctic sea. In this work, Expressed Sequence Tags (EST) from cells exposed to three different temperatures; 15 degrees C, 0 degrees C and -12 degrees C were generated to identify genes associated with cold adaptation. A total of 5376 clones from each library were randomly picked and sequenced. Comparative analyses from the resulting ESTs in each condition identified several groups of genes required for cold adaptation. Additionally, 319 unique transcripts that encoded uncharacterised functions were identified in the -12 degrees C library and are currently unique to G. antarctica. Gene expression analysis using RT-qPCR revealed two of the unknown genes to be up-regulated at -12 degrees C compared to 0 degrees C and 15 degrees C. These findings further contribute to the collective knowledge into G. antarctica cold adaptation and as a resource for understanding the ecological and physiological tolerance of psychrophilic microbes in general. PMID- 29598998 TI - World Health Organisation Classification of Lymphoid Tumours in Veterinary and Human Medicine: a Comparative Evaluation of Gastrointestinal Lymphomas in 61 Cats. AB - To diagnose and classify the various entities of lymphomas, the World Health Organisation (WHO) classification is applied in human as well as in veterinary medicine. We validated the concordance of these classification systems by having a veterinary and human pathologist evaluate gastrointestinal lymphoma tissue from 61 cats. In 59% of all cases, there was a match between their respective diagnoses of the lymphoma subtype. A complete consensus between the two evaluators was obtained for all samples with a diagnosis of diffuse large B-cell lymphoma, T-cell anaplastic large cell lymphoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. A corresponding diagnosis was also made in the majority of samples with enteropathy associated T-cell lymphoma (EATL) type II, although this subtype in cats has similarities to the 'indolent T cell lymphoproliferative disorder of the gastrointestinal tract', a provisional entity newly added to the revised human WHO classification in 2016. Very little consensus has been found with cases of EATL type I due to the fact that most did not meet all of the criteria of human EATL I. Hence, the human pathologist assigned them to the heterogeneous group of peripheral T-cell lymphomas (not otherwise specified). Consequently, concrete guidelines and advanced immunophenotyping based on the model of human medicine are essential to differentiate these challenging entities in veterinary medicine. PMID- 29598999 TI - Pulmonary Basaloid Squamous Cell Carcinoma in a Dog. AB - A 9-year-old neutered male crossbred dog with a 4-week history of progressive vestibulocerebellar signs was presented for necropsy examination. Gross examination revealed neoplastic growth in the lungs, thoracic lymph nodes, left kidney and cerebellum. Microscopically, the tumour consisted of an infiltrative, densely cellular, basaloid epithelial neoplastic growth with extensive areas of abrupt keratinization. Immunohistochemically, neoplastic cells expressed p63 and partially expressed cytokeratins 5/6. Based on these findings, the tumour was diagnosed as a primary pulmonary basaloid squamous cell carcinoma (BSSC) with metastasis to regional lymph nodes, kidney and brain. As far as the authors are aware, this is the first description of BSCC in an animal species. PMID- 29599000 TI - Neoplasia in Three Aye-Ayes (Daubentonia madagascariensis). AB - Tumours diagnosed in three aged captive aye-ayes (Daubentonia madagascariensis), held in two different institutions, are described. A cerebral glioblastoma was diagnosed based on histological and immunohistochemical findings in one of the animals following initial presentation with bilateral mydriasis, absent pupillary reflex, head tilt and ataxia. A second animal was humanely destroyed due to impaired locomotion associated with spondylosis and a post-mortem diagnosis of cholangiocarcinoma was made based on histology with further confirmation with immunohistochemical labelling for cytokeratin 7. A third aye-aye suffering from dental disease was diagnosed with an oral squamous cell carcinoma following an excisional biopsy from a non-healing wound in the lip. Due to progression of the neoplasia the animal was humanely destroyed and post-mortem examination revealed the presence on an additional unilateral phaeochromocytoma. PMID- 29599001 TI - Parotid Salivary Gland Basal Cell Adenocarcinoma in a Big-eared Opossum (Didelphis aurita). AB - The opossum (family Didelphidae) is a marsupial endemic to the Americas. Apart from the South American short-tailed opossum (Monodelphis domestica) and the Virginia opossum (Didelphis virginiana), there is considerable lack of knowledge about the health and diseases of most opossum species. Among these, the big-eared opossum (Didelphis aurita) is found in Argentina, Brazil and Paraguay. Natural and experimental studies have shown this species to be susceptible to infectious agents with zoonotic potential and the animals may play a role in transmission of such agents. However, neoplasia appears to be uncommon in this species. We describe the gross, microscopical and immunohistochemical features of a parotid salivary gland basal cell adenocarcinoma in a free-living big-eared opossum. This case represents the first report of salivary gland neoplasia in opossums. PMID- 29599002 TI - Amyloid-producing Odontoameloblastoma in a Black-tailed Prairie Dog (Cynomys ludovicianus). AB - A 6-year-old female black-tailed prairie dog (Cynomys ludovicianus) was presented with a space-occupying lesion in the left submandibular region. On computed tomography, a low attenuating, poorly circumscribed mass infiltrated the left mandibular bone, with osteolytic change. Microscopically, the lesion was composed of odontogenic epithelium proliferating in nests and embedded in abundant dental papilla-like ectomesenchyme, including dentine and enamel. Multifocal amyloid deposition was observed. Immunohistochemically, the neoplastic epithelial cells were positive for cytokeratin (CK) AE1/AE3, CK14 and p63. Some epithelial cells were positive for amelogenin and some adjacent to the amyloid deposits co expressed S100. The ectomesenchymal cells expressed vimentin and strong S100 immunoreactivity was observed in odontoblast-like cells. The amyloid was immunolabelled with amelogenin. The tumour was diagnosed as amyloid-producing odontoameloblastoma.

AB - A 17-year-old female emu (Dromaius novaehollandiae) was presented for clinical evaluation due to a 3-week history of anorexia and progressive weight loss. The emu died after sedation. At necropsy examination, the ovary and the majority of the oviduct were effaced by a multinodular cystic mass and accompanied by 6 l of coelomic effusion. Histopathology revealed a neoplasm composed of well differentiated, poorly organized tissues derived from ectoderm, mesoderm and endoderm. Tissues within the neoplasm expressed glial fibrillary acidic protein, desmin and cytokeratins AE1/AE3, respectively, confirming the diagnosis of teratocarcinoma. PMID- 29599004 TI - Pathology and Distribution of Velogenic Viscerotropic Newcastle Disease Virus in the Reproductive System of Vaccinated and Unvaccinated Laying Hens (Gallus gallus domesticus) by Immunohistochemical Labelling. AB - This study investigated the pathological changes in the reproductive system of laying hens that lead to the poor egg production and quality in Newcastle disease (ND) and the distribution of the virus in the system. Two hundred and forty Isa Brown pullets were divided randomly into vaccinated and unvaccinated groups (n = 120 each). The vaccinated group was given Hitchner B1 vaccine at 1 day of age, La Sota vaccine at 4 weeks of age and Komarov vaccine at 9 and 16 weeks of age. At the peak of egg production, the laying hens (32 weeks old) were assigned randomly into four groups (n = 60): VC, vaccinated with ND vaccines and inoculated intramuscularly with velogenic viscerotropic ND virus (vvNDV); VU, vaccinated unchallenged; UC, unvaccinated challenged; and UU, unvaccinated unchallenged. UC hens showed depression, diarrhoea and later torticollis. Mortality in UC hens was 90%. VC hens showed mild anorexia. The body weights of the UC hens were significantly (P <0.05) lower than those of UU hens. VC and UC hens showed a significant (P <0.05) drop in egg production. Only UC hens produced abnormal eggs and initially had swollen, oedematous, hyperaemic oviducts followed by atrophy and shortening of the reproductive tract with atresia of the ovarian follicles. The histopathological changes were of necrosis of the epithelium and secretory glands. VC hens showed mild inflammatory changes in the oviduct. Immunohistochemical labelling showed extensive presence of the virus in the ovary, infundibulum, magnum, isthmus, uterus and vagina of UC hens and in the ovary of VC hens. These changes will be the cause of serious egg production problems, especially in vaccinated layers in countries where vvNDV is enzootic. PMID- 29599005 TI - Inflammatory Lesion Patterns in Target Organs of Visna/Maedi in Sheep and their Significance in the Pathogenesis and Diagnosis of the Infection. AB - Ovine visna/maedi (VM) infection is characterized by the development of chronic inflammatory lesions in different organs, mainly in the lung, mammary gland and central nervous system (CNS), with either histiocytic or lymphocytic pattern predominance being described in the CNS. To help to understand the role of host immune response in the development of these patterns, 50 naturally-infected sheep and eight non-infected sheep from intensive milk-producing flocks were studied. The histological lesion patterns in the three main target organs in each sheep were characterized. Lesion severity was determined, including minimal lesions. A histiocytic pattern was observed in 23 sheep (46%), a lymphocytic inflammatory pattern in 19 sheep (38%) and a mixed inflammatory pattern in eight sheep (16%). Forty animals showed moderate or severe lesions (80%), while 10 had minimal lesions (20%). Moderate or severe lesions affected only one target organ in 20 sheep (50%), two organs in 14 sheep (35%) and all three target organs in six sheep (15%). Infection was confirmed by immunohistochemistry (IHC) using an antibody specific for p28 of VM virus/caprine arthritis and encephalitis virus and by polymerase chain reaction (PCR) in all sheep. Minimal inflammatory lesions associated with positive IHC and PCR were observed. The results suggest that the development of a predominant inflammatory pattern in different organs within the same animal may be related to the host immune response. Minimal and focal lesions, not considered previously, should be taken into account when formulating a differential diagnosis in affected sheep. PMID- 29599006 TI - [Association between burnout syndrome and anxiety in residents and anesthesiologists of the Federal District]. AB - BACKGROUND AND OBJECTIVE: There is a shortage of studies addressing the association between burnout syndrome and anxiety among anesthesiologists. Identifying the relationship between these two conditions is of fundamental importance for the prevention, follow-up, and treatment of the professionals. Thus, we evaluated the association between burnout syndrome and anxiety in anesthesiologists and residents of anesthesiology in the Federal District. METHOD: A cross-sectional study using a convenience sample of residents and anesthesiologists from the Federal District. The correlation between State Trait Anxiety Inventory and Burnout Syndrome (Maslach Burnout Inventory) was tested using multiple linear regression analysis, considering a significance level of 5%. RESULTS: Of the 78 completed forms, there were predominance of males (57.69%), mean age of 42 +/- 9.7 years for anesthesiologists and 30 +/- 2.9 years for residents. Burnout syndrome had a prevalence of 2.43% among anesthesiologists and 2.70% among resident physicians, while a high risk for its manifestation was 21.95% in anesthesiologists and 29.72% in resident physicians. There was a correlation between state-anxiety and the variables burnout emotional exhaustion, burnout depersonalization, and trait-anxiety. Regarding trait-anxiety, there was no statistically significant correlation with other variables. CONCLUSIONS: There is association between state-anxiety and the emotional exhaustion dimensions of burnout, burnout depersonalization, and trait-anxiety. The occurrence of anxiety can negatively influence the way the individual faces daily stressors, which may be related to the use of ineffective strategies to cope with stress. PMID- 29599007 TI - Radiation Dose Reduction at Low Tube Voltage CCTA Based on the CNR Index. AB - RATIONALE AND OBJECTIVES: We compared the radiation dose and diagnostic accuracy on 120- and 100-kVp coronary computed tomography angiography (CCTA) scans whose contrast-to-noise ratio (CNR) was the same. MATERIALS AND METHODS: We studied 1311 coronary artery segments from 100 patients. For 120-kVp scans, the targeted image level was set at 25 Hounsfield units (HU). For 100-kVp scans, the targeted noise level was set at 30 HU to obtain the same CNR as at 120 kVp. We compared the CNR and the radiation dose on scans acquired at 120 and 100 kVp. Invasive coronary angiography (ICA) images were evaluated by an interventional coronary angiography specialist, and CCTA images were evaluated by a radiologist. Coronary artery disease was defined as a luminal narrowing ?50% for ICA and CCTA. With ICA considered the gold standard, the diagnostic accuracy (sensitivity, specificity, positive predictive value, and negative predictive value) was analyzed on both 120- and 100-kVp CCTA images. We also compared the diagnostic accuracy for area under the receiver operating characteristic curve of the ICA and CCTA performed at 120 and 100 kVp. Two blinded observers visually evaluated the septal branch. RESULTS: The mean dose-length product was 48% lower at 100 kVp than at 120 kVp (P < .01). Under the 120-kVp CCTA protocol, the area under the curve, 95% confidence interval, sensitivity, specificity, positive predictive value, and negative predictive value were 0.94%, 0.91%-0.96%, 94.0%, 93.0%, 82.3%, and 98.1%, respectively; at 100 kVp these values were 0.94%, 0.92%-0.97%, 96.1%, 92.0%, 85.2%, and 98.0%, respectively. Area under the receiver operating characteristic curve analysis revealed no significant difference in diagnostic accuracy between the two protocols (P = .87). CONCLUSIONS: At the same CNR, the 100-kVp CCTA protocol may help to reduce the radiation dose by approximately 50% compared to the 120-kVp protocol without degradation of diagnostic accuracy.

PMID- 29599009 TI - Incremental Prognostic Value of Apparent Diffusion Coefficient Histogram Analysis in Head and Neck Squamous Cell Carcinoma. AB - RATIONALE AND OBJECTIVES: We aimed to investigate the incremental prognostic value of apparent diffusion coefficient (ADC) histogram analysis in patients with head and neck squamous cell carcinoma (HNSCC) and integrate it into a multivariate prognostic model. MATERIALS AND METHODS: A retrospective review of magnetic resonance imaging findings was conducted in patients with pathologically confirmed HNSCC between June 2012 and December 2015. For each tumor, six histogram parameters were derived: the 10th, 50th, and 90th percentiles of ADC (ADC10, ADC50, and ADC90); mean ADC values (ADCmean); kurtosis; and skewness. The clinical variables included age, sex, smoking status, tumor volume, and tumor node metastasis stage. The association of these histogram and clinical variables with overall survival (OS) was determined. Further validation of the histogram parameters as independent biomarkers was performed using multivariate Cox proportional hazard models combined with clinical variables, which was compared to the clinical model. Models were assessed with C index and receiver operating characteristic curve analyses for the 12- and 36-month OS. RESULTS: Ninety-six patients were eligible for analysis. Median follow-up was 877 days (range, 54 1516 days). A total of 29 patients died during follow-up (30%). Patients with higher ADC values (ADC10 > 0.958 * 10-3 mm2/s, ADC50 > 1.089 * 10-3 mm2/s, ADC90 > 1.152 * 10-3 mm2/s, ADCmean > 1.047 * 10-3 mm2/s) and lower kurtosis (<=0.967) were significant predictors of poor OS (P < .100 for all). After adjusting for sex and tumor node metastasis stage, the ADC90 and kurtosis are both significant predictors of OS with hazard ratios = 1.00 (95% confidence interval: 1.001-1.004) and 0.58 (95% confidence interval: 0.37-0.90), respectively. By adding the ADC parameters into the clinical model, the C index and diagnostic accuracies for the 12- and 36-month OS showed significant improvement. CONCLUSIONS: ADC histogram analysis has incremental prognostic value in patients with HNSCC and increases the performance of a multivariable prognostic model in addition to clinical variables.

AB - Radiology practice will be altered by the coming of artificial intelligence, and the process of learning in radiology will be similarly affected. In the short term, radiologists will need to understand the first wave of artificially intelligent tools, how they can help them improve their practice, and be able to effectively supervise their use. Radiology training programs will need to develop curricula to help trainees acquire the knowledge to carry out this new supervisory duty of radiologists. In the longer term, artificially intelligent software assistants could have a transformative effect on the training of residents and fellows, and offer new opportunities to bring learning into the ongoing practice of attending radiologists. PMID- 29599011 TI - Anti-N-methyl-d-aspartate receptor encephalitis in children: Incidence and experience in Hong Kong. AB - AIM: The study aims to analyze the incidence, clinical features, investigation findings and treatment outcomes of anti-N-methyl-d-aspartate receptor encephalitis in children from Hong Kong. METHOD: A retrospective study was carried out on paediatric patients diagnosed with anti-NMDAR encephalitis in Hong Kong from January 2009 to December 2015. RESULTS: Fifteen patients (67% female, 93% Chinese) were identified over seven years and the estimated incidence in Hong Kong was 2.2/million children per year (95% CI 1.2-3.6). The median age of presentation was 12 years (range 1-17 years). The most common symptom groups observed were abnormal psychiatric behavior or cognitive dysfunction (14/15, 93%) and seizures (14/15, 93%), followed by speech dysfunction (13/15, 87%), movement disorders (12/15, 80%), decreased level of consciousness (10/15, 67%) and autonomic dysfunction or central hypoventilation (5/15, 33%). The median number of symptom groups developed in each patient was 5 (range 3-6). All patients were treated with intravenous immunoglobulin and/or steroids. Three patients (20%) with more severe presentation required additional plasmapheresis and rituximab. Outcome was assessable in 14 patients. Among those eleven patients who had only received intravenous immunoglobulin and/or steroids, nine patients (82%) achieved full recovery. One patient (9%) had residual behavioral problem, while another one (9%) who developed anti-NMDAR encephalitis after herpes simplex virus encephalitis was complicated with dyskinetic cerebral palsy and epilepsy. Among those three patients who required plasmapheresis and rituximab, one (33%) had full recovery and two (66%) had substantial recovery. The median duration of follow up was 20.5 months (range 3-84 months). CONCLUSION: Anti-NMDAR encephalitis is an acquired, severe, but potentially treatable disorder. Ethnicity may play a role in the incidence of anti-NMDAR encephalitis and we have provided a local incidence with the majority of patients being Chinese. The diagnosis of anti-NMDAR encephalitis should be considered in children presenting with a constellation of symptoms including psychiatric and neurological manifestations. Patients may respond to first line immunotherapy. For those who do not, second line therapy is indicated in order to achieve a better outcome. PMID- 29599012 TI - Metaorganisms in extreme environments: do microbes play a role in organismal adaptation? AB - From protists to humans, all animals and plants are inhabited by microbial organisms. There is an increasing appreciation that these resident microbes influence the fitness of their plant and animal hosts, ultimately forming a metaorganism consisting of a uni- or multicellular host and a community of associated microorganisms. Research on host-microbe interactions has become an emerging cross-disciplinary field. In both vertebrates and invertebrates a complex microbiome confers immunological, metabolic and behavioural benefits; conversely, its disturbance can contribute to the development of disease states. However, the molecular and cellular mechanisms controlling the interactions within a metaorganism are poorly understood and many key interactions between the associated organisms remain unknown. In this perspective article, we outline some of the issues in interspecies interactions and in particular address the question of how metaorganisms react and adapt to inputs from extreme environments such as deserts, the intertidal zone, oligothrophic seas, and hydrothermal vents. PMID- 29599013 TI - An allometric analysis of sexual dimorphism in Ctenomys australis: integrating classic morphometry and functional performance in vivo. AB - The South American rodents of the genus Ctenomys (Rodentia, Hystricognathi), which use both forelimbs and incisors to dig, show strong, specialized morphological adaptations to living in the underground niche. In these rodents, the effectiveness of a bite - in this case the potential to inflict physical damage - mostly depends on the strength of the incisors (e.g. bending and torsion stresses) and the power of the masseteric muscle of the jaw. Ctenomys australis (the sand dune tuco-tuco) is a highly territorial subterranean rodent that builds large and exclusive burrow systems in coastal sand dunes found continuously along the Atlantic coast of the Buenos Aires province, Argentina. Incisors in this species are used both in agonistic encounters among congeners (i.e. reproductive or territorial intentions) as well as to dig and increase the size of their burrows daily (e.g. acquisition of plant material as food resources). We first characterized sexual dimorphism in cranial traits involved in aggressive interactions between males, analyzing ontogenetic trajectories of both sexes. We also analyzed some remarkable attributes of sexual dimorphism in subadult and adult individuals, the bending and torsion stresses and the bite performance in vivo, hypothesizing that males are able to apply comparatively stronger bite forces at their incisor tips than females, concordant with a broader mandible for the insertion of a powerful adductor musculature. Bite forces were measured in vivo in wild animals of both sexes using a strain gauge load cell force transducer. These individuals were also used to estimate the incisor area (CA), the 2nd moment of inertia of the incisors (I, or the bending strength to external forces), and the torsional strength of the incisor (J), all traits involved in the production of the force that can be withstood at the incisor tips. Ontogeny explained some sexual differences in the cranial traits of adults, expressed as (i) morphological changes related to body size variation, and (ii) morphological changes associated with differences in the slope of ontogenetic trajectories (regardless of body size variation). Recordings of in vivo bite forces were significantly higher in adult males than in females. These differences in bite forces were not associated with the sex itself, but the sexual dimorphism in body size. Although males did not show significantly higher allometric coefficients for I, J and CA than females, males still showed a strong sexual dimorphism in these traits due to body size variation. On the other hand, measurements of mandibular width - an estimator of the relative size of masseteric muscles - in vivo showed strong differences between sexes, suggesting higher force performance at the incisor tips for males. Overall, we observed that many attributes related to bite performance might have been molded by sexual selection, which implies differences in allometric coefficients from some morphological traits throughout ontogeny.

PMID- 29599017 TI - Opioid prescribing practices from 2010 through 2015 among dentists in the United States: What do claims data tell us? AB - BACKGROUND: Dentists wrote 6.4% of all opioid prescriptions in the United States in 2012. The purpose of this study was to examine opioid prescription rates, dosage of opioids prescribed, type of opioid drug prescribed, and type of dental visit at which dentists prescribe opioids. METHODS: The authors used the 2010 through 2015 Truven Health Marketscan Research databases and the Prescription Drug Monitoring Program (PDMP) Training and Technical Assistance Center conversion data set. The authors conducted descriptive analyses for days' supply, quantity prescribed, and daily morphine milligram equivalent dose. RESULTS: The opioid prescription rate per 1,000 dental patients increased from 130.58 in 2010 to 147.44 in 2015. Approximately 68.41% of all opioids prescribed were during surgical dental visits and approximately 31.10% during nonsurgical dental visits. During nonsurgical dental visits at which dentists prescribed an opioid, most of the procedures were restorative. CONCLUSIONS: Among a population of dental patients with private insurance, opioid prescribing rates in the United States increased slightly from 2010 to 2015. The largest increase was among 11- through 18-year-olds. Almost one-third of opioid prescriptions written by dentists were associated with nonsurgical dental visits. PRACTICAL IMPLICATIONS: Use of PDMP resources and use of nonopioid analgesics could help reduce the number of opioid prescriptions in dentistry. PMID- 29599018 TI - Sex and race or ethnicity disparities in opioid prescriptions for dental diagnoses among patients receiving Medicaid. AB - BACKGROUND: The objective of this study was to identify specific factors (sex, race or ethnicity, and health care provider type) associated with patient receipt of an opioid prescription after a dental diagnosis. METHODS: The authors used Medicaid claims dated from January 1, 2013, through September 30, 2015, for 13 US states in this study. The authors identified oral health-related conditions by using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes 520.0 through 529.9. RESULTS: During the 2013-2015 study period, among the more than 890,000 Medicaid patients with a dental diagnosis, 23% received an opioid within 14 days of diagnosis. Female patients were 50% more likely to receive an opioid for pain management of a dental condition than were men (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.52 to 1.55). Non-Hispanic whites and African Americans were approximately twice as likely to receive opioids than were Hispanics (OR, 2.11; 95% CI, 2.05 to 2.17 and OR, 1.88; 95% CI, 1.83 to 1.93, respectively). Patients receiving oral health care in an emergency department were nearly 5 times more likely to receive an opioid prescription than were patients treated in a dental office (OR, 4.66; 95% CI, 4.59 to 4.74). Patients with a dental condition diagnosed were nearly 3 times as likely to receive an opioid from a nurse practitioner as from a dentist (OR, 2.64; 95% CI, 2.57 to 2.70). Opioid use was substantially higher among African American female patients (OR, 3.29; 95% CI, 3.18 to 3.40) and non-Hispanic white female patients (OR, 3.24; 95% CI, 3.14 to 3.35) than among Hispanic female patients. CONCLUSIONS: Opioid prescribing patterns differ depending on patient race or ethnicity, sex, and health care provider source in patients with a dental diagnosis in the United States. PRACTICAL IMPLICATIONS: Dentists are providing substantially less opioid prescriptions compared to their medical colleagues for pain treatment following a dental diagnosis in the Medicaid population. When considering pain management for dental and related conditions, dentists should continue with conservative prescribing practices as recommended.

AB - BACKGROUND: Effective pain management is a priority in dental practice. Government and private agencies highlight the need to provide optimal pain relief, balancing potential benefits and harms of both opioid and nonopioid analgesic agents. The purpose of this study is to summarize the available evidence on the benefits and harms of analgesic agents, focusing on preexisting systematic reviews. TYPES OF STUDIES REVIEWED: An overview of systematic reviews was conducted to evaluate the efficacy or reported adverse events associated with orally administered medication or medication combinations for relief of acute pain. Reviews were inclusive of all age populations but were limited to those that evaluated medication and medication combinations marketed in the United States and had moderate or high methodological quality according to the A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 tool. RESULTS: Five reviews were found eligible for inclusion. The data identified combinations of ibuprofen and acetaminophen as having the highest association with treatment benefit in adult patients and the highest proportion of adult patients who experienced maximum pain relief. Diflunisal, acetaminophen, and oxycodone were found to have the longest duration of action in adult patients. Medication and medication combinations that included opioids were among those associated most frequently with acute adverse events in both child and adult-aged patient populations. PRACTICAL IMPLICATIONS: The best available data suggested that the use of nonsteroidal medications, with or without acetaminophen, offered the most favorable balance between benefits and harms, optimizing efficacy while minimizing acute adverse events.

AB - In this paper, a novel mathematical model is developed for robust periodic capacitated arc routing problem (PCARP) considering multiple trips and drivers and crew's working time to study the uncertain nature of demand parameter. The objective function of the proposed model aims to minimize total traversed distance and total usage cost of vehicles over a planning period. To solve the problem, an improved hybrid simulated annealing algorithm (SA) is developed based on a heuristic algorithm and an efficient cooling equation. It has been proved that the performance of the proposed algorithm is acceptable in comparison with the exact solution method. Finally, the results have shown the effects of different uncertainty level of the demand parameter on the problem to be considered as a managerial overview in decision making process under uncertainty. PMID- 29599023 TI - Comparative environmental and human health evaluations of thermolysis and solvolysis recycling technologies of carbon fiber reinforced polymer waste. AB - This quantitative research aims to compare environmental and human health impacts associated with two recycling technologies of CFRP waste. The 'baseline' recycling technology is the conventional thermolysis process via pyrolysis and the 'alternative' recycling technology is an emerging chemical treatment via solvolysis using supercritical water (SCW) to digest the thermoset matrix. Two Gate-to-Gate recycling models are developed using GaBi LCA platform. The selected functional unit (FU) is 1 kg CFRP waste and the geographical boundary of this comparative LCIA is defined to be within the U.S. The results of this comparative assessment brought to light new insights about the environmental and human health impacts of CFRP waste recycling via solvolysis using SCW and, therefore, helped close a gap in the current state of knowledge about sustainability of SCW-based solvolysis as compared to pyrolysis. Two research questions are posed to identify whether solvolysis recycling offers more environmental and human health gains relative to the conventional pyrolysis recycling. These research questions lay the basis for formulating two null hypotheses (H0,1 and H0,2) and their associated research hypotheses (H1,1 and H1,2). LCIA results interpretation included 'base case' scenarios, 'sensitivity studies,' and 'scenarios analysis.' The results revealed that: (a) recycling via solvolysis using SCW exhibits no gains in environmental and human health impacts relative to those impacts associated with recycling via pyrolysis and (b) use of natural gas in lieu of electricity for pyrolyzer's heating reduces the environmental and human health impacts by 37% (lowest) and up to 95.7% (highest). It is recommended that on going experimental efforts that focus only on identifying the best solvent for solvolysis-based recycling should also consider quantification of the energy intensity as well as environmental and human health impacts of the proposed solvents. PMID- 29599024 TI - Plastic recycling in the Nordics: A value chain market analysis. AB - There is low utilisation of plastic waste in the Nordic region and only a fraction of plastic materials go back into production processes through reuse and recycling practices. This paper aims to increase knowledge concerning factors that inhibit demand for recycled plastics, and to identify critical barriers for plastic recycling across the regional plastics value chain. A literature review and targeted interviews with key actors across the plastics value chain enabled the mapping of interactions between the major actors and identified hotspots that act as barriers to the flow of plastic materials. Barriers identified include the lack of both supply and demand of recycled plastic and are mainly attributed to the fragmented market of secondary materials. The main hotspots identified are the low demand due to price considerations, insufficient traceability and transparency in value chain transactions, and general design deficiencies in the recyclability of products. Value chain coordination is considered as the most important intervention by the interviewees, followed by the need for increased investment in innovation and technology development. Complementary measures that could counteract the identified barriers include public procurement for resource efficiency, ban on the incineration of recyclable materials, and specifications on the design of plastic products for reducing the number of different polymers, and the number and usage of additives. PMID- 29599025 TI - The type of approach does not influence TKA component position in revision total knee arthroplasty - A clinical study using 3D-CT. AB - BACKGROUND: The influence of the surgical approach on the position of the prosthetic components in revision of total knee arthroplasties (rTKA) is still not clear. This study compared the medial parapatellar approach (MPA) and lateral parapatellar subvastus approach with tibial tubercle osteotomy (LPA). METHODS: Forty-two consecutive patients underwent rTKA from 2006 to 2016 with either MPA (n=21) or LPA (n=21) because of aseptic loosening, infection, malposition or instability (mean follow-up: 41.5months). Revision TKA component position and leg alignment were assessed on three-dimensional CT (3D-CT) images and compared between groups using a t-test (p<0.05). Rotation of rTKA components graded into internal, neutral or external rotation and rates of postoperative complications and revisions were compared between groups with a chi2-test (p<0.05). RESULTS: Group MPA and LPA showed no significant differences with respect to the femoral component (coronal: 0.6 degrees vs 0.9 degrees ; sagittal: 7.5 degrees vs 7.7 degrees ; transversal: 0.4 degrees vs -0.2 degrees ), tibial component (coronal: 0.1 degrees vs 0.3 degrees ; sagittal: 3.1 degrees vs 1.6 degrees ; transversal: 6.9 degrees vs 9.3 degrees ) and leg alignment (varus: 0.2 degrees vs 1.1 degrees ) (p<0.05). Group LPA showed a non-significant (p=0.25) higher incidence of neutrally (28.6% vs 9.5%) and less internally (23.8% vs 38.1%) rotated tibial components. Rates of complication and revisions did not differ significantly. CONCLUSIONS: In contrast with primary TKA, the two approaches did not influence postoperative rTKA position. This can be explained with the more extensive approach at rTKA and means that no corrections of the orientation of the components are needed performing either MPA or LPA. PMID- 29599027 TI - Predictors of the effect of bariatric surgery on knee osteoarthritis pain. AB - INTRODUCTION: Bariatric surgery reduces obesity and knee osteoarthritis (OA) pain, but some patients improve more than others. We aimed to identify characteristics that predict this knee pain improvement. METHODS: We reviewed NYU Langone Health bariatrics records (2002-2015) and called eligible patients reporting pre-operative knee pain. Patients were asked to rate their pain on a 10 point scale at three time points: before surgery, one year post-surgery, and time of survey administration. Subjects were asked about pre-operative knee injuries and surgeries, presence of OA in other joints, and OA family history. Data were analyzed using paired t-tests and ANOVA. RESULTS: Of 125 eligible patients reporting knee pain, we analyzed the 120 patients who had laparoscopic gastric band (LAGB) surgery. The cohort was 78.3% female, with an average age at surgery of 49.7 +/- 10.2 years. There was no correlation between pre-operative body mass index (BMI) and knee pain reduction at one year post-LAGB, but the subgroup with the most BMI improvement reported the most knee improvement (p = 0.043). We found significantly better pain reduction after one year in younger patients (p = 0.009). Those with prior knee injuries improved less than those who were injury free (p = 0.044), but a history of prior knee surgery was not similarly significant. Patients with multifocal OA improved less (p = 0.001). CONCLUSION: Younger knee OA patients and those without prior knee injury or other OA involvement, experience more knee pain relief from LAGB weight loss surgery. LAGB may be a viable treatment option for knee OA pain, irrespective of the degree of obesity.

PMID- 29599028 TI - Phenotypic characterization of patients with rheumatologic manifestations of common variable immunodeficiency. AB - : Patients with common variable immunodeficiency (CVID) have a higher incidence of rheumatologic disorders. To delineate this clinical association, we investigated the phenotypic features of patients with CVID affected by these conditions. METHODS: We conducted a retrospective analysis of 870 pediatric and adult patients with CVID included in the United States Immunodeficiency Network (USIDNET) registry. Outcomes included clinical characteristics (age, gender, ethnicity, rheumatologic diagnosis, and comorbidities), infectious history and basic immunophenotype (serum immunoglobulin levels, CD19+ B cells, and CD4/CD8 ratio) in patients with CVID and rheumatologic disorders compared to those with non-inflammatory CVID. Demographic and clinical data were compared using chi square, Fisher's exact or Wilcoxon-Mann-Whitney tests. Non-parametric tests, single and multiple logistic regression models were used to evaluate the relationship between CVID-associated rheumatologic disorders and basic immunophenotypic parameters (IgA, IgM, CD19+ B-cell counts, and CD4/CD8 ratios). RESULTS: Physician-reported rheumatic diseases were present in 5.9% of patients with CVID (n = 51) included in the registry. Although CVID affects both sexes equally, and patients are of predominantly White-Caucasian ethnicity, there were more females (3.3:1 female to male ratio) and increased proportion of non-white patients in the rheumatologic disease group (p < 0.05). Specific disorders included: inflammatory arthritis (n = 18), Sjogren's syndrome (n = 11), SLE (n = 8), Raynaud's syndrome (n = 8), vasculitis (n = 9), MCTD (n = 3), and other (n = 5). In about one-third of patients, a rheumatologic condition was associated with an additional inflammatory complication or malignancy. In regards to the immunophenotype parameters compared (CD19+ B-cell counts, CD4/CD8 ratio, IgA, and IgM), no significant differences were demonstrated between the two groups. CONCLUSION: Our findings highlight the coexistence of primary antibody immunodeficiencies and systemic rheumatologic disorders, describe the spectrum of rheumatologic manifestations, and contrast differences in relevant demographic, clinical and immunophenotype parameters in the largest registry of CVID patients in the U.S. In spite of its limitations, our study details the intersection of systemic autoimmunity and CVID and provides valuable insights into these two groups of disorders. Further delineating the link between systemic autoimmunity and humoral immunodeficiencies can provide novel insights into the immune abnormalities underlying these related conditions. PMID- 29599030 TI - Pulmonary Hypertension in Central Australia: A Community-Based Cohort Study. AB - BACKGROUND: The burden of pulmonary hypertension (PHT) in Central Australia has not been previously studied. Our aim is to characterise the prevalence, clinical classification, and long-term survival of individuals with PHT in Central Australia. METHODS: A community-based cohort study of all individuals diagnosed with PHT in Central Australia between 2005 and 2016 was undertaken. We estimated PHT prevalence using population data, describe clinical PHT classification, and characterised long-term survival using Kaplan-Meier approaches. RESULTS: A total of 183 patients were identified (mean age 52+/-16years, 63% female). Of these individuals, 149 (81.4%) were of Aboriginal and Torres Strait Islander (ATSI) descent. The prevalence per 100,000 of any PHT was significantly higher In ATSI (723 [95% CI 608-839] compared to non-ATSI individuals (126 [95% CI 84-168], p<0.001). Furthermore, ATSI individuals were diagnosed at younger ages compared to non-ATSI individuals (49+/-15 vs 64+/-16years, p<0.001). Median estimated pulmonary artery systolic pressure (ePASP) was higher in patients with pulmonary arterial hypertension (PAH) compared to other causes (62 [IQR 54-69] vs 50 [IQR 44-58] mmHg, p<0.01). The median survival rate from diagnosis was 9 years (IQR 7.2-13.2). Age and ePASP were significant predictors of mortality (HR 1.05 [95% CI 1.02-1.07] and HR 1.56 [95% 1.00-2.42] respectively). CONCLUSIONS: In this community based study, we found a high burden of PHT in Central Australia. The prevalence of PHT is greater in ATSI individuals and is diagnosed at younger ages compared to non-ATSI individuals. Together with other cardiovascular diseases, PHT may be in-part contributing to the gap in life expectancy between ATSI and non-ATSI individuals.

PMID- 29599032 TI - Femoral Bone Restoration Patterns in Revision Total Hip Arthroplasty Using Distally Fixed Modular Tapered Titanium Stems and an Extended Trochanteric Osteotomy Approach. AB - BACKGROUND: Mechanical failure of modular revision stems is a serious complication in revision total hip arthroplasty. The lack of adequate osseous support to the proximal component, especially in cases of an extended trochanteric osteotomy approach, is considered a risk factor for stem failure. In this study, we analyze proximal bone regeneration patterns in patients undergoing revision total hip arthroplasty for aseptic stem loosening through an extended trochanteric osteotomy approach using an uncemented dual modular stem. METHODS: Fifty-four patients treated for aseptic stem loosening were radiologically reviewed. The femur was divided according to the Gruen zones. Preoperative bone loss, formation of new cancellous bone, and presence of direct osseous contact to the stem were noted right away for each Gruen zone. The presence of osseous support at the modular junction and the proximal component were examined. RESULTS: All patients showed restoration of proximal bone mass at final follow up. New bone formation was first seen in more distally located Gruen zones. Cases with longer proximal components had a trend toward earlier osseous support at the modular junction. Overall, 75% of patients showed osseous support at the modular junction 2 years after surgery. CONCLUSION: Restoration of proximal bone occurs in a distal to proximal direction. Shorter proximal components require more time until osseous support to the modular junction is achieved, which may result in a higher risk of mechanical failure. Based on this study, bony support at the modular junction should not be expected in 25% of cases 2 years after surgery. PMID- 29599033 TI - Periarticular Ropivacaine Cocktail Is Equivalent to Liposomal Bupivacaine Cocktail in Bilateral Total Knee Arthroplasty. AB - BACKGROUND: This study compares the effectiveness of 2 commonly used periarticular injection formulations: liposomal bupivacaine and bupivacaine (EXP) and ropivacaine, epinephrine, ketorolac, and clonidine (ROP) in patients undergoing bilateral total knee arthroplasty or unicompartmental knee arthroplasty. METHODS: Twenty-six total knee arthroplasty patients (52 knees) and 3 unicompartmental knee arthroplasty patients (6 knees) undergoing simultaneous, bilateral arthroplasty were randomized to receive periarticular injections in a blinded fashion. Even birth year patients were selected for PAI of EXP in the right knee and ROP in the left knee. This was reversed for odd birth years. Visual analog scale pain scores for each knee and patient perceived difference in knee functional recovery were recorded during physical therapy, throughout the hospitalization. RESULTS: There was no difference in visual analog scale pain scores between the EXP and ROP injected knees at any time point during the first 2 days after surgery. Postoperative pain scores averaged 41.9 mm (range 0-100 mm) for EXP and 43.1 mm (range 0-100 mm) for ROP. Patients were unable to detect a difference in the functional recovery between their knees on postoperative day 0, 1, or 2. No complications as a result of either periarticular injection occurred. CONCLUSION: Periarticular injections of EXP and ROP are equally effective after knee arthroplasty and patients do not appreciate differences between knees as determined by pain score or perceived functional recovery during the first 2 days after bilateral knee arthroplasty. This study demonstrates that a liposomal bupivacaine injection does not add an incremental benefit for pain control compared to a less expensive injection formulation. PMID- 29599034 TI - Clinical Outcomes and Bearing-Specific Complications Following Fourth-Generation Alumina Ceramic-on-Ceramic Total Hip Arthroplasty: A Single-Surgeon Series of 749 Hips at a Minimum of 5-Year Follow-Up. AB - BACKGROUND: The purpose of this study is to evaluate the minimum 5-year outcomes and bearing-specific complications in a single surgeon series of fourth generation alumina ceramic-on-ceramic total hip arthroplasties (THAs). METHODS: We retrospectively analyzed 667 patients (749 hips) who underwent primary THAs by a single surgeon using fourth-generation alumina ceramic bearings. There were 315 men and 352 women with a mean age of 54.2 years. The surgeon used cementless prostheses with an identical design and BIOLOX Delta ceramics in all hips, using a 36-mm head in 472 hips (63%) and a 32-mm head in 227. The mean follow-up duration was 6.5 years (range, 5 to 8 years). RESULTS: The mean Harris hip score improved from 45.6 points preoperatively to 91.3 points at final follow-up. All but 1 acetabular cup and all femoral stems were well fixed. No radiographic evidence of osteolysis was identified at final follow-up. There were 2 (0.3%) ceramic liner fractures and no ceramic head fractures. A total of 48 hips (6.4%) exhibited audible noise (29 clickings and 19 squeakings), but no patient required revision. Other complications were 1 dislocation, 1 deep infection, 3 iliopsoas tendonitis, and 6 periprosthetic femoral fractures. Kaplan-Meier survivorship for revision for any reason was 98.6% (95% confidence interval, 97.7-99.5) at 6.5 years. CONCLUSION: Delta ceramic-on-ceramic THAs had a high rate of survivorship without radiographic evidence of osteolysis at 6.5-year follow-up. However, we found 0.3% ceramic liner fractures and 6.4% audible noises associated with the use of Delta ceramics. PMID- 29599035 TI - What Is the Role of Diagnostic and Therapeutic Sonication in Periprosthetic Joint Infections? AB - BACKGROUND: Periprosthetic joint infection (PJI) is one of the most dreaded complications in joint replacement surgery. Diagnosis and treatment can be difficult and biofilms are of major concern due to their low susceptibility toward antibiotics. METHODS: This review focuses on the use of sonication as an evolving diagnostic and adjunct treatment modality in the context of PJI. Therapeutic application of sonication is discussed separately for its (i) direct action on bacteria, (ii) synergistic effects with antibiotics, and (iii) effects on release of antibiotics from bone cement. RESULTS: Used as a diagnostic tool, sonication shows promising results with respect to sensitivity and specificity when compared to conventional methods, notably after previous administration of antibiotics. As an adjunct treatment modality, the chemical, physical, and mechanical effects of sonication are primarily driven by cavitation and recognized as the main cause for bactericidal effects but the exact underlying mechanisms have not been identified yet. Sonication alone does not have the ability to completely eradicate biofilms but synergistic effects when used in conjunction with antibiotics have been reported. There is also evidence for enhanced antibiotic release from bone cement. CONCLUSION: Sonication is as an evolving modality in the context of PJIs. As a diagnostic tool, it has not been introduced in routine clinical practice and sonication as a treatment modality in PJIs is still in an experimental stage. Factors such as frequency, pressure, chemical activity, intensity, and exposure time need to be evaluated for optimal application of sonication and may also improve study comparison.

PMID- 29599038 TI - Neer Award 2018: the effect of preoperative education on opioid consumption in patients undergoing arthroscopic rotator cuff repair: a prospective, randomized clinical trial. AB - BACKGROUND: Opioids are commonly administered for the treatment of acute and chronic pain symptoms. The current health care system is struggling to deal with increasing medication abuse and rising mortality rates from overdose. Preoperative patient-targeted education on opioid use is an avenue yet to be explored. The purpose of the study was to determine whether preoperative narcotics education reduces consumption after arthroscopic rotator cuff repair (ARCR). METHODS: Patients undergoing primary ARCR at our institution were randomized to receiving opioid-related preoperative education or not. Patients filled out preoperative questionnaires detailing complete medical history and visual analog scale (VAS) for pain. Patients completed questionnaires regarding their opioid consumption and pain at their 2-week, 6-week, and 3-month follow-up. RESULTS: The study enrolled 140 patients. Patients in the study group consumed significantly less narcotics than the control group at the 3-month follow-up. Patients in the education group were 2.2 times more likely to discontinue narcotic use by the end of follow-up (odds ratio, 2.19; P = .03). In addition, patients with a history of preoperative narcotic use that were in the education group were 6.8 times more likely to discontinue narcotics by the end of follow-up (odds ratio, 6.8; P = .008). DISCUSSION/CONCLUSIONS: The findings of this study determined that preoperative education intervention significantly decreased the number of narcotic pills consumed at 3 months after ARCR. In addition, education resulted in earlier cessation of opioids; therefore, directed patient education can help alleviate the current opioid epidemic. PMID- 29599040 TI - Volumetric locking free 3D finite element for modelling of anisotropic visco hyperelastic behaviour of anterior cruciate ligament. AB - Solids such as polymers, soft biological tissues display visco-hyperelastic, isochoric and finite deformation behaviour. The incompressibility constraint imposed severe restriction on the displacement field results in volumetric locking. Many techniques have been developed to address the issue such as reduced integration, mixed formulation, B-Bar and F-Bar methods, each of them with their own merits and demerits. In this work, we have developed a 3D finite element (hereby referred as J-Bar method) to counter volumetric locking in visco hyperelastic solids. To validate the proposed J-Bar method, rheological characteristics of the human anterior cruciate ligament (ACL) were predicted and compared with the experimental results. PMID- 29599041 TI - Between-day reliability of MyotonPRO for the non-invasive measurement of muscle material properties in the lower extremities of patients with a chronic spinal cord injury. AB - Measuring the muscle properties of patients with spinal cord injuries (SCIs) is important to better understand their biomechanical features. In this study, we sought to evaluate the between-day reliability of MyotonPRO, a handheld device that can measure muscle mechanical properties, and assess whether it is reliable to measure muscle properties over time in patients with SCI. Thirteen men with complete SCIs (age 53.9 +/- 6.3 years, height 171.0 +/- 5.2 cm, weight 66.1 +/- 5.8 kg), and injury levels ranging from L1 to T12, were enrolled. Oscillation frequency; logarithmic decrement; dynamic stiffness; mechanical stress relaxation time; and creep of the biceps femoris, medial and lateral gastrocnemius, rectus femoris, tibialis anterior, and Achilles tendon were measured on consecutive days using MyotonPRO. The intraclass coefficient for most muscles and the Achilles tendon ranged from 0.53 to 0.99 for all parameters. The percentage standard error of the measurement for many parameters in most muscles and the Achilles tendon was less than 10%. Bland-Altman analysis showed a high agreement for all mechanical properties. No significant differences were observed in any muscle or Achilles tendon properties between days (all p > 0.05). These results indicate that the MyotonPRO is reliable for between-day measurements of the mechanical properties of lower limb muscles and Achilles tendon in patients with SCI. PMID- 29599039 TI - The relationship of whole human vertebral body creep to geometric, microstructural, and material properties. AB - Creep, the time dependent deformation of a structure under load, is an important viscoelastic property of bone and may play a role in the development of permanent deformity of the vertebrae in vivo leading to clinically observable spinal fractures. To date, creep properties and their relationship to geometric, microstructural, and material properties have not been described in isolated human vertebral bodies. In this study, a range of image-based measures of vertebral bone geometry, bone mass, microarchitecture and mineralization were examined in multiple regression models in an effort to understand their contribution to creep behavior. Several variables, such as measures of mineralization heterogeneity, average bone density, and connectivity density persistently appeared as significant effects in multiple regression models (adjusted r2: 0.17-0.56). Although further work is needed to identify additional tissue properties to fully describe the portion of variability not explained by these models, these data are expected to help understand mechanisms underlying creep and improve prediction of vertebral deformities that eventually progress to a clinically observable fracture. PMID- 29599042 TI - Assessing delay and lag in sagittal trunk control using a tracking task. AB - Slower trunk muscle responses are linked to back pain and injury. Unfortunately, clinical assessments of spine function do not objectively evaluate this important attribute, which reflects speed of trunk control. Speed of trunk control can be parsed into two components: (1) delay, the time it takes to initiate a movement, and (2) lag, the time it takes to execute a movement once initiated. The goal of this study is to demonstrate a new approach to assess delay and lag in trunk control using a simple tracking task. Ten healthy subjects performed four blocks of six trials of trunk tracking in the sagittal plane. Delay and lag were estimated by modeling trunk control for predictable and unpredictable (control mode) trunk movements in flexion and extension (control direction) at movement amplitudes of 2 degrees , 4 degrees , and 6 degrees (control amplitude). The main effect of control mode, direction, and amplitude of movement were compared between trial blocks to assess secondary influencers (e.g., fatigue). Only control mode was consistent across trial blocks with predictable movements being faster than unpredictable for both delay and lag. Control direction and amplitude effects on delay and lag were consistent across the first two trial blocks and less consistent in later blocks. Given the heterogeneity in the presentation of back pain, clinical assessment of trunk control should include different control modes, directions, and amplitudes. To reduce testing time and the influence of fatigue, we recommend six trials to assess trunk control. PMID- 29599043 TI - Reprint of "In response to Tomas, D. et al. (2017).

AB - PURPOSE: We examine changes to health insurance coverage and access to health care among children, adolescents, and young adults since the implementation of the Affordable Care Act. METHODS: Using the National Health Interview Survey, bivariate and logistic regression analyses were conducted to compare coverage and access among children, young adolescents, older adolescents, and young adults between 2010 and 2016. RESULTS: We show significant improvements in coverage among children, adolescents, and young adults since 2010. We also find some gains in access during this time, particularly reductions in delayed care due to cost. While we observe few age-group differences in overall trends in coverage and access, our analysis reveals an age-gradient pattern, with incrementally worse coverage and access rates for young adolescents, older adolescents, and young adults. CONCLUSIONS: Prior analyses often group adolescents with younger children, masking important distinctions. Future reforms should consider the increased coverage and access risks of adolescents and young adults, recognizing that approximately 40% are low income, over a third live in the South, where many states have not expanded Medicaid, and over 15% have compromised health.

PMID- 29599049 TI - Socioeconomic determinants as risk factors for squamous cell carcinoma of the head and neck: a case-control study in Iran. AB - Our aim was to assess the association between different components of sociodemographic status and the risk of developing squamous cell carcinoma (SCC) of the head and neck after we had adjusted for the influence of the known behavioural risk factors of smoking and drinking alcohol. We selected 146 patients with histopathologically-confirmed SCC of the head and neck, and matched them for age and sex with 266 healthy controls for this case-control study. Personal details, occupation, socioeconomic status, smoking, and alcohol consumption were recorded. The association of sociodemographic variables with oral cancer was evaluated both separately and with a composite socioeconomic index. Chi squared tests, adjusted odds ratios (OR), and 95% CI were computed using logistic regression to estimate the effect. There was a significant difference between the two groups in the composite socioeconomic index (p<0.001). The group with "low" socioeconomic status had the highest risk of oral cancer (OR=3.89, 95% CI 1.28 to 11.82). Better-educated people with higher incomes had a lower risk of SCC of the head and neck after we had controlled for behavioural risk factors. However, marital and employment status and place of residence were not significantly associated with risk. Our findings confirm that some socioeconomic determinants were associated with the development of oral cancer in this study group.

PMID- 29599051 TI - The effect of diabetes on functional outcomes among individuals with distal radial fractures. AB - STUDY DESIGN: Prospective cohort study. INTRODUCTION: Diabetes is reported to adversely affect outcomes; however, its effect on distal radial fractures (DRF) is not well examined. PURPOSE OF THE STUDY: This study investigated the effect of diabetes on pain, hand function, physical health status, grip strength, and wrist and forearm range of motion among patients with DRF. METHODS: A total of 479 patients with DRF were classified into patients with and without diabetes based on self-report. Patient-Rated Wrist Evaluation assessed pain and hand function. The Short Form-12 assessed physical health status. Both questionnaires examined DRF recovery at baseline, 3 month, and 1 year. RESULTS: There was a significant improvement in Patient-Rated Wrist Evaluation scores over time (69 [19] to 25 [22]; 76 [15] to 20 [20] for patients with and without diabetes respectively, P < .01) with a significant interaction between time and diabetes (P < .01), indicating that patients with diabetes recovered more slowly than the rest of the cohort. There was an improvement over time on physical status (36 [12] to 45 [12]; 39 [9] to 50 [9], P < .01), grip strength (16 [7] to 24 [10]; 15 [9] to 24 [10], P < .01), and range of motion (flexion [42 {14} to 49 {15}; 43 {15} to 54 {14}, P < .01], extension [45 {11} to 52 {11}; 46 {13} to 53 {12}, P < .01], pronation [73 {10} to 77 {9}; 73 {11} to 78 {9}, P < .01], and supination [58 {17} to 65 {14}; 61 {17} to 70 {12}, P < .01]) for patients with and without diabetes, respectively. Patients with diabetes did not differ significantly in these secondary outcomes compared to the rest of the cohort. DISCUSSION AND CONCLUSION: Although individuals with diabetes had good outcomes, their recovery was slower than the rest of the cohort. This may be due to the adverse effect of hyperglycemia on bone tissues and small blood vessels. Future studies are required to assess how severity and duration of diabetes affect outcomes after DRF. PMID- 29599052 TI - Can Sepsis Be Detected in the Nursing Home Prior to the Need for Hospital Transfer? AB - OBJECTIVES: To determine whether and to what extent simple screening tools might identify nursing home (NH) residents who are at high risk of becoming septic. DESIGN: Retrospective chart audit of all residents who had been hospitalized and returned to participating NHs during the study period. SETTING AND PARTICIPANTS: A total of 236 NH residents, 59 of whom returned from hospitals with a diagnosis of sepsis and 177 who had nonsepsis discharge diagnoses, from 31 community NHs that are typical of US nursing homes overall. MEASURES: NH documentation of vital signs, mental status change, and medical provider visits 0-12 and 13-72 hours prior to the hospitalization. The specificity and sensitivity of 5 screening tools were evaluated for their ability to detect residents with incipient sepsis during 0-12 and 13-72 hours prior to hospitalization: The Systemic Inflammatory Response Syndrome criteria, the quick Sequential Organ Failure Assessment (SOFA), the 100-100-100 Early Detection Tool, and temperature thresholds of 99.0 degrees F and 100.2 degrees F. In addition, to validate the hospital diagnosis of sepsis, hospital discharge records in the NHs were audited to calculate SOFA scores. RESULTS: Documentation of 1 or more vital signs was absent in 26%-34% of cases. Among persons with complete vital sign documentation, during the 12 hours prior to hospitalization, the most sensitive screening tools were the 100-100-100 Criteria (79%) and an oral temperature >99.0 degrees F (51%); and the most specific tools being a temperature >100.2 degrees F (93%), the quick SOFA (88%), the Systemic Inflammatory Response Syndrome criteria (86%), and a temperature >99.0 degrees F (85%). Many SOFA data points were missing from the record; in spite of this, 65% of cases met criteria for sepsis. CONCLUSIONS: NHs need better systems to monitor NH residents whose status is changing, and to present that information to medical providers in real time, either through rapid medical response programs or telemetry. PMID- 29599053 TI - The Omega-6:Omega-3 ratio: A critical appraisal and possible successor. AB - The well-known health effects of the long-chain, marine omega-3 (n-3) fatty acids (FAs) has led to a growing interest in the prognostic value that blood levels of these FAs might have vis-a-vis cardiovascular and neurocognitive diseases. The measurement and expression of n-3 FA levels is not straight-forward, however, and a wide variety of means of expression of n-3 FA status have been used in research and clinical medicine. This has led to considerable confusion as to what "optimal" n-3 FA status is. The n-6:n-3 ratio has enjoyed relatively widespread use, but this apparently simple metric has both theoretical and practical difficulties that have contributed to misunderstandings in this field. Just as the once-popular polyunsaturated:saturated FA ratio has largely disappeared from the nutritional and medical literature, it may be time to replace the n-6:n-3 ratio with a newer metric that focuses on the primary deficiency in Western diets - the lack of eicosapentaenoic and docosahexaenoic acids (EPA and DHA). The Omega 3 Index (red blood cell EPA+DHA) has much to recommend it in this regard.

PMID- 29599055 TI - Effect of participation in a park-based afterschool program on cardiovascular disease risk among severely obese youth. AB - OBJECTIVES: The prevalence of severe obesity in youth is rising, despite reports of obesity rates stabilizing overall. While reports on treatment outcomes for youth with severe obesity (bariatric surgery, behavioral and pharmacological treatments) exist, very few community-based programs have reported changes in health outcomes in this population. We assessed changes in cardiovascular health risk profiles among racial/ethnic minority youth with severe obesity who participated in Fit2PlayTM, a park-based afterschool health promotion program. STUDY DESIGN: A longitudinal cohort study. METHODS: Children aged 6-14 years (N = 1546, 51% Hispanic, 44% non-Hispanic black) who participated in the Fit2PlayTM in one of 34 urban park sites for one school year over five separate school years (2010-2015) had height, weight, four-site skinfold thicknesses, systolic blood pressure (SBP)/diastolic blood pressure (DBP), fitness tests, and a health/wellness knowledge test collected at the beginning and end of the school year. Two-level repeated measures mixed models examined changes in cardiovascular health outcomes (body mass index [BMI], skinfold thickness, systolic/diastolic blood pressure percentile [SBPP/DBPP], cardiorespiratory fitness [PACER]) in youth with severe obesity over 1- and 2-year follow-up. RESULTS: Compared with baseline, BMI decreased 13% (incidence rate ratio [IRR] 95% confidence interval [CI]: 0.83-0.90), sumof skinfold thicknesses decreased 5% (IRR 95% CI: 0.91 0.99), SBPP decreased 5% (IRR 95% CI: 0.90-0.99), DBPP decreased 19% (IRR 95% CI: 0.77-0.86), and PACER scores increased 12% (IRR 95% CI: 1.0-1.27) after two years of participation in the Fit2PlayTM program. CONCLUSIONS: Findings here support community/park-based youth programs as effective and accessible treatment options for reducing cardiovascular disease risk among youth with severe obesity. PMID- 29599056 TI - Building evaluation capacity in Ontario's public health units: promising practices and strategies. AB - OBJECTIVES: This article presents the findings of a project focusing on building evaluation capacity in 10 Ontario public health units. The study sought to identify effective strategies that lead to increased evaluation capacity in the participating organizations. STUDY DESIGN: This study used a qualitative, multiple case research design. METHODS: An action research methodology was used to design customized evaluation capacity building (ECB) strategies for each participating organization, based on its specific context and needs. This methodological approach also enabled monitoring and assessment of each strategy, based on a common set of reporting templates. A multiple case study was used to analyze the findings from the 10 participating organizations and derive higher level findings. RESULTS: The main findings of the study show that most of the strategies used to increase evaluation capacity in public health units are promising, especially those focusing on developing the knowledge, skills, and attitudes of health unit staff and managers. Facilitators to ECB strategies were the engagement of all staff members, the support of leadership, and the existence of organizational tools and infrastructure to support evaluation. It is also essential to recognize that ECB takes time and resources to be successful. CONCLUSIONS: The design and implementation of ECB strategies should be based on organizational needs. These can be assessed using a standardized instrument, as well as interviews and staff surveys. The implementation of a multicomponent approach (i.e. several strategies implemented simultaneously) is also linked to better ECB outcomes in organizations.

AB - Mass concentrations of chemical compounds in both PM2.5 (particle aerodynamic diameter, Dp < 2.5 MUm) and PM2.5-10 (2.5 < Dp < 10 MUm), and acidity of aerosol particles were measured at an urban site in western Japan using a continuous dichotomous Aerosol Chemical Speciation Analyzer (ACSA-12) throughout 2014. Mass concentrations of both PM2.5 and sulfate had distinct seasonal variabilities with maxima in spring and winter, mostly due to long-range transport with the prevailing westerly wind. Mass concentration of nitrate in PM2.5 (fNO3) showed an obvious warm-season-low and cold-season-high pattern as a result of both gas aerosol phase equilibrium processes under high temperature conditions as well as transport. Nitrate in PM2.5-10 (cNO3) increased during long-range transport of dust, implying the great importance of heterogeneous processes at the surface of coarse mode particles. In this study, Delta[H+] (derived from the difference in pH of extract liquid with/without sampling) was used to indicate the acidity of particles. We found that acidity of particles in PM2.5 (fDeltaH) was mostly positive with a maximum in August because of the large fraction of nitrate and sulfate. Acidity of particles in PM2.5-10 (cDeltaH) was negative in winter and spring due to presence of alkaline matter from crustal sources. This study highlights the great importance of anthropogenic pollutants on the acidity of particles in the western Pacific Ocean and further impact on the marine environment and climate. PMID- 29599061 TI - Cholesteatoma labyrinthine fistula: prevalence and impact. AB - INTRODUCTION: Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. OBJECTIVE: Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. METHODS: This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. RESULTS: We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p=0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. CONCLUSION: Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic modality for lateral semicircular canal fistula. Sensorineural hearing loss can occur post-surgically, even in previously unaffected patients despite the technique employed. PMID- 29599062 TI - [Harlequin syndrome: Two sides of the same disease]. PMID- 29599063 TI - [Management of heart failure in cardiology and primary care (MICCAP) program: Improving the management of patients with heart failure]. AB - Despite current treatments, morbidity and mortality of patients with heart failure remain high. The late diagnosis of heart failure, the insufficient heart failure treatment (i.e. not using the appropriate drugs, prescribing lower doses of drugs than recommended, etc.), and a poor coordination between different health care levels, may explain, at least in part, these figures. The Management of Heart Failure in Cardiology and Primary Care (MICCAP) program has been developed with the aim of optimising the integrated management of patients with heart failure between Primary Care and Cardiology, through the improvement of coordination between both health care levels. This includes continuous medical education to reinforce the diagnostic and therapeutic skills of general practitioners in the field of heart failure. The rationale and objectives of the MICCAP program are summarised in this article. PMID- 29599064 TI - Black Country Lungs: a moving exploration of COPD in a post-industrial community. PMID- 29599066 TI - Experimental and numerical study of platelets rolling on a von Willebrand factor coated surface. AB - Blood platelets circulate in the blood and adhere to wounded vessels to initiate coagulation and healing. The first step of this process is the capture of flowing platelets by adhesive molecules located at the wounded vessel wall. In this article, we study the transport of fixed blood platelets in a microfluidic channel coated with von Willebrand factor (vWF), a large multimeric protein expressed by endothelial cells in the vicinity of wounds. We measure the number of platelets adsorbed at the channel surface as a function of both time and space. Experimental results are compared with a new transport model. We show that transverse diffusion is an important feature of our model, while the rolling behaviour of the bounded platelets can be neglected. PMID- 29599065 TI - The retinoid X receptor agonist, 9-cis UAB30, inhibits cutaneous T-cell lymphoma proliferation through the SKP2-p27kip1 axis. AB - BACKGROUND: Bexarotene (Targretin(r)) is currently the only FDA approved retinoid X receptor (RXR) -selective agonist for the treatment of cutaneous T-cell lymphomas (CTCLs). The main side effects of bexarotene are hypothyroidism and elevation of serum triglycerides (TGs). The novel RXR ligand, 9-cis UAB30 (UAB30) does not elevate serum TGs or induce hypothyroidism in normal subjects. OBJECTIVES: To assess preclinical efficacy and mechanism of action of UAB30 in the treatment of CTCLs and compare its action with bexarotene. METHODS: With patient-derived CTCL cell lines, we evaluated UAB30 function in regulating growth, apoptosis, cell cycle check points, and cell cycle-related markers. RESULTS: Compared to bexarotene, UAB30 had lower half maximal inhibitory concentration (IC50) values and was more effective in inhibiting the G1 cell cycle checkpoint. Both rexinoids increased the stability of the cell cycle inhibitor, p27kip1 protein, in part, through targeting components involved in the ubiquitination-proteasome system: 1) decreasing SKP2, a F-box protein that binds and targets p27kip1 for degradation by 26S proteasome and 2) suppressing 20S proteasome activity (cell line-dependent) through downregulation of PSMA7, a component of the 20S proteolytic complex in 26S proteasome. CONCLUSIONS: UAB30 and bexarotene induce both early cell apoptosis and suppress cell proliferation. Inhibition of the G1 to S cell cycle transition by rexinoids is mediated, in part, through downregulation of SKP2 and/or 20S proteasome activity, leading to increased p27kip1 protein stability. Because UAB30 has minimal effect in elevating serum TGs and inducing hypothyroidism, it is potentially a better alternative to bexarotene for the treatment of CTCLs. PMID- 29599067 TI - Editor's Choice - A Comparison of Clinical Outcomes Between Primary Bypass and Secondary Bypass After Failed Plain Balloon Angioplasty in the Bypass versus Angioplasty for Severe Ischaemia of the Limb (BASIL) Trial. AB - OBJECTIVE: Chronic limb threatening ischaemia (CLTI) is a growing global health problem. The UK NIHR HTA funded BASIL trial is still the only randomised controlled trial to have compared a "bypass surgery first" with a "plain balloon angioplasty (PBA) first" strategy for the management of CLTI. In patients who were likely to survive for 2 years and had a suitable vein, primary bypass (PB) was associated with better clinical outcomes. Furthermore, PBA was associated with a high technical and clinical failure rate and many went on to have secondary bypass (SB). This study aimed at comparing clinical outcomes following PB and SB in the BASIL trial. METHODS: Demographic, procedural, and outcome data were obtained from the BASIL case report forms. Outcomes were amputation free survival (AFS), limb salvage (LS), overall survival (OS), and freedom from revascularisation (FFR). The SB cohort comprises patients whose first trial intervention was PBA and who subsequently underwent bypass during follow up. The PB cohort comprises those patients whose first trial intervention was bypass. RESULTS: The 190 PB and 49 SB patients were well matched except that the SB patients were more likely to be current smokers. At a median of 7 years, PB was associated with better AFS (PB 60% vs. SB 40%; HR 1.58, p = .04), LS (PB 85% vs. SB 73%, p = .06), and OS (PB 68% vs. 51%, p = .06). FFR was equivalent (PB 53% vs. 53%, p = .3). CONCLUSION: In the BASIL trial, clinical outcomes following PB were significantly better than in patients undergoing SB after failed PBA. Prior to treating patients with CLTI with primary PBA, clinicians should consider that if this should fail, the outcome of attempted subsequent bypass is likely to be significantly worse than if PB were attempted. PMID- 29599069 TI - Blood Lead Levels of Children in Flint, Michigan: 2006-2016. AB - OBJECTIVE: We evaluated the increases in blood lead levels (BLLs) observed in young children in Flint, Michigan, during their exposure to corrosive Flint River water during the years 2014 and 2015 and compared their BLLs to those of Flint children measured during the years 2006-2013 and 2016. STUDY DESIGN: This was a retrospective study design using BLLs extracted from databases from 2006 to 2016. We analyzed a population sample of 15 817 BLLs from children aged <=5 years with potential exposure to contaminated Flint River water. Percentages of BLLs >=5.0 ug/dL and geometric mean (GM) BLLs were analyzed over time. RESULTS: A significant decline in the percentages of BLLs >=5.0 ug/dL from 11.8% in 2006 to 3.2% in 2016 was observed (P < .001). GM +/- SE BLLs decreased from 2.33 +/- 0.04 ug/dL in 2006 to 1.15 +/- 0.02 ug/dL in 2016 (P < .001). GM BLLs increased twice: from 1.75 +/- 0.03 ug/dL to 1.87 +/- 0.03 ug/dL (2010-2011) and from 1.19 +/- 0.02 ug/dL to 1.30 +/- 0.02 ug/dL (2014-2015). Overall, from 2006 to 2016, there was a 72.9% decrease in the percentage of children with BLLs >=5.0 ug/dL and a 50.6% decrease in GM BLLs. CONCLUSION: These findings suggest that the 11 year trend of annual decreases in BLLs in children in Flint, Michigan, reversed to a degree consistent with random variation from 2010 to 2011, and again during the exposure to Flint River water in 2014-2015. Historically, public health efforts to reduce BLLs of young children in Flint have been effective over the 11-year period studied. PMID- 29599071 TI - Maintaining normothermia: Why and how? AB - A high incidence of postnatal hypothermia has been reported in high-as well low resource countries and it remains an independent predictor of neonatal morbidity and mortality, especially in very preterm infants in all settings. The temperature of newly born infants should be maintained between 36.5 and 37.5 degrees C after birth through admission and stabilization. Interventions to achieve this may include environmental temperature 23-25 degrees C, use of radiant warmers, exothermic mattresses, woollen or plastic caps, plastic wraps, humidified and heated gases. Skin-to-skin contact has been used, especially in low-resource settings. The combinations of these interventions applied to quality improvement initiatives, including staff training, use of checklists, and continuous feedback with the staff involved in the management of the neonate, are key factors to prevent heat loss from delivery room to admission to the neonatal intensive care unit. The admission temperature should be recorded as a predictor of outcomes as well as a quality indicator. PMID- 29599068 TI - Acute Responses to Diuretic Therapy in Extremely Low Gestational Age Newborns: Results from the Prematurity and Respiratory Outcomes Program Cohort Study. AB - OBJECTIVE: To determine if daily respiratory status improved more in extremely low gestational age (GA) premature infants after diuretic exposure compared with those not exposed in modern neonatal intensive care units. STUDY DESIGN: The Prematurity and Respiratory Outcomes Program (PROP) was a multicenter observational cohort study of 835 extremely premature infants, GAs of 230/7-286/7 weeks, enrolled in the first week of life from 13 US tertiary neonatal intensive care units. We analyzed the PROP study daily medication and respiratory support records of infants <=34 weeks postmenstrual age. We determined whether there was a temporal association between the administration of diuretics and an acute change in respiratory status in premature infants in the neonatal intensive care unit, using an ordered categorical ranking of respiratory status. RESULTS: Infants in the diuretic exposed group of PROP were of lower mean GA and lower mean birth weight (P < .0001). Compared with infants unexposed to diuretics, the probability (adjusted for infant characteristics including GA, birth weight, sex, and respiratory status before receiving diuretics) that the exposed infants were on a higher level of respiratory support was significantly greater (OR, >1) for each day after the initial day of diuretic exposure. CONCLUSIONS: Our analysis did not support the ability of diuretics to substantially improve the extremely premature infant's respiratory status. Further study of both safety and efficacy of diuretics in this setting are warranted. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01435187. PMID- 29599070 TI - Postoperative D-dimer predicts venous thromboembolism in patients undergoing urologic tumor surgery. AB - PURPOSE: We examined the incidence of pulmonary thromboembolism (PE) and deep venous thromboembolism (DVT) in patients who underwent urologic tumor surgery. The aim of this study was to investigate the postoperative D-dimer for prediction of venous thromboembolism events (VTE), as well as to identify other risk factors associated with the occurrence of thromboembolisms. PATIENTS AND METHODS: This was a prospective observational cohort study, which included 1,269 patients who underwent major urologic tumor surgery, from August 2015 to February 2017, at our center. Data comprising age, sex, body mass index, Charlson comorbidity index, type of surgery, Caprini score, postoperative D-dimer levels, and other laboratory tests were collected for analyses. Lower limb venous ultrasound was performed before surgery and the day before hospital discharge to measure DVT. Computerized tomography or ventilation/perfusion lung scan was applied to detect PE. RESULTS: The overall incidence of VTE was 2.4% (31 cases) in 1,269 patients, consisting of 23 PE events and 9 DVT events. Patients undergoing radical cystectomy were most likely to suffer VTE (4.3%). The optimal cutoff value for postoperative D-dimer was 0.98MUg/ml, according to the receiver operating characteristic curve analysis, with a sensitivity of 83.9%, and a specificity of 80.0%. On multivariate analysis, hypertension (odds ratio, OR = 2.5, 95% CI: 1.1 5.7; P = 0.026), Charlson comorbidity index >= 2 (OR = 5.6, 95% CI: 2.2-14.6; P<0.001), and D-dimer lever >= 1MUg/ml on postoperative day 1 (OR = 12.52, 95% CI: 4.6-35.2; P<0.001) were independently associated with VTE after urologic tumor surgery. CONCLUSIONS: The overall incidence of urologic-tumor-surgery associated VTE in an Asian population is similar to those reported in European and North American series. Elevated D-dimer early after operation is an independent predictor of VTE in patients undergoing urologic tumor surgery. In addition, hypertension and the Charlson comorbidity index are both important clinical risk factors. The Caprini score recommended by the guideline is inadequate in this study population. The postoperative D-dimer plasma level is a more reliable marker for identifying patients at high-risk of developing venous thromboembolisms. PMID- 29599072 TI - Preoperative immobility significantly impacts the risk of postoperative complications in bariatric surgery patients. AB - BACKGROUND: Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes. OBJECTIVES: The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes. SETTING: This study took place at a university hospital in the United States. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications. RESULTS: There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, P<.001) and greater operative times, length of stay, reoperation rates, and readmissions. Immobile patients had a greater risk of multiple complications, including acute renal failure (OR 6.42, P<.001), pulmonary embolism (OR 2.44, P = .01), cardiac arrest (OR 2.81, P = .05), and septic shock (OR 2.78, P = .02). Regardless of procedure type, immobile patients had a higher incidence of perioperative morbidity compared with ambulatory patients. CONCLUSIONS: This study is the first to specifically assess the impact of immobility on 30-day bariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery. PMID- 29599073 TI - Adjustable gastric banded plication versus sleeve gastrectomy: the role of gastrectomy in weight loss. AB - BACKGROUND: Laparoscopic adjustable gastric banded plication (LAGBP) is a procedure that has a stomach volume similar to the sleeve gastrectomy (SG). It has shown promising results but has not been adopted widely. OBJECTIVE: To determine the difference gastrectomy has on weight loss and complications. SETTING: Private practice, United States. METHODS: A retrospective, matched cohort analysis of LAGBP and SG patients was found through matching body mass index and sex for each LAGBP to a SG patient. Body mass index, percentage excess weight loss, and total weight loss percentage were analyzed. Complication data were also collected on a short- (<30 d) and long- (>30 d) term basis. Complication rates were then compared. Data were analyzed through descriptive statistics. RESULTS: Patients who received SG lost more body mass index, percentage excess weight loss, and total weight loss percentage at 1 year and started to gain weight between 1 and 2 years. LAGBP patients weight loss also peaked at 1 year but maintained their weight loss to year 2. SG patients lost more weight at all time points, and the difference was statistically significant (P<.05). LAGBP and SG patients had statistically similar rates of short- and long term complication rates. In the LAGBP group (57 patients) 5, 9, 13, 14, 14, and 17 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively. In the SG group (57 patients) 11, 10, 11, 13, 20, and 29 patients were lost to follow-up at 3, 6, 9, 12, 18, and 24 months, respectively. CONCLUSION: Both procedures have peak weight loss at 1 year with acceptable complication rates. However, the SG starts to regain weight while the LAGBP shows weight stability. More time is needed to see if the weight loss curves will intersect or if the late band complications will also happen with the LAGBP as they have with band placement without plication. PMID- 29599074 TI - Radiographic evaluation of the normal ankle joint in children and adolescent. AB - BACKGROUND: The purpose of this study was to determine the reliability of numerous radiographic measurements of the skeletally immature ankle joint, timing of ossification of medial malleolus and appearance of tibial incisura and differences in the values of radiographic measurements based on age and sex. METHODS: This study included 590 subjects (0-15 years), who underwent ankle AP, lateral and mortise radiographs. Presence of the medial malleolus and incisura fibularis were recorded. Tibiofibular overlap, tibiofibular clear space, medial clear space, talar tilt, talocrural angle, relative fibular width and fibular position were measured. RESULTS: All radiographic measurements showed good to excellent intraobserver and interobserver reliability (ICCs, 0.603 to 0.949). The timing of ossification of medial malleolus and appearance of tibial incisura between boys and girls were not different. Tibiofibular clear space on mortise views, and medial clear space on AP and mortise view significantly decreased by age. Tibiofibular overlap on AP and mortise views, relative fibular width on AP view significantly increased by age. Talocrural angle, tibiofibular overlap on AP view, tibiofibular clear space on AP and mortise views, medial clear space on AP and mortise views and fibular position were significantly larger in boys than in girls. The difference in tibiofibular overlap, tibiofibular clear space and medial clear space on AP view of both sides was <50% in 97.1%, 93.1%, and 97.2% of patients, respectively. The difference in tibiofibular overlap, tibiofibular clear space and medial clear space on mortise view of both sides was <50% in 98.0%, 96.5%, and 100% of patients, respectively. CONCLUSIONS: For skeletally immature patients, the criteria for absolute radiographic values used in adults to assess distal tibiofibular syndesmosis or deltoid ligament injury cannot be applied, but comparison of both sides of ankle joint could help physicians to predict the need for additional evaluations. PMID- 29599075 TI - Percutaneous endoscopic gastrostomy in patients with amyotrophic lateral sclerosis: Mortality and complications. AB - INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that causes severe dysphagia and weight loss. Percutaneous endoscopic gastrostomy (PEG) is currently the technique of choice for the enteral nutrition of these patients. OBJECTIVES: To analyse mortality and complications in a series of patients diagnosed with ALS who underwent PEG, and to evaluate factors related to patient survival after the procedure. MATERIAL AND METHODS: We performed a prospective, observational study including all patients diagnosed with ALS and treated by our hospital's Gastroenterology Department in the period 1997-2013. We studied mortality, complications, and clinical and biochemical parameters, and correlated these with the survival rate. RESULTS: The study included a total of 57 patients, of whom 49 were ultimately treated with PEG. ALS onset was bulbar in 30 patients and spinal in 19. Mortality during the procedure and at 30 days was 2% (n = 1). Six patients (12.2%) experienced major complications; 17 (34.7%) experienced less serious complications which were easily resolved with conservative treatment. No significant differences were observed in forced vital capacity, albumin level, or age between patients with (n = 6) and without (n = 43) major complications. CONCLUSIONS: PEG is an effective, relatively safe procedure for the enteral nutrition of patients with ALS, although not without morbidity and mortality. Neither forced vital capacity nor the form of presentation of ALS were associated with morbidity in PEG. PMID- 29599076 TI - Characteristics of PPT1 and TPP1 enzymes in neuronal ceroid lipofuscinosis (NCL) 1 and 2 by dried blood spots (DBS) and leukocytes and their application to newborn screening. AB - We first characterized PPT1 and TPP1 enzymes in dried blood spots (DBS), plasma/serum, and leukocytes/lymphocytes using neuronal ceroid lipofuscinosis (NCL) 1 and 2 patients and control subjects. PPT1 enzyme had only one acid form in control DBS, plasma/serum, and leukocytes/lymphocytes and showed deficient activities in these samples from NCL 1 patients. Conversely, TPP1 enzymes in control DBS and leukocytes/lymphocytes consisted of two forms, an acidic form and a neutral form, whereas serum TPP1 enzyme had only a neutral form. In control subjects, the optimal pH of PPT1 enzyme in DBS, plasma/serum, and leukocytes/lymphocytes was 4.5 to 5.0 in the acidic form, whereas TPP1 enzyme in control DBS and leukocytes/lymphocytes was pH 4.5 and 6.5, respectively. In NCL 1 and 2, both PPT1 and TPP1 enzyme activities in DBS, plasma, and leukocytes/lymphocytes were markedly reduced in acidic pH, whereas heterozygotes of NCL 1 and 2 in the acidic form showed intermediate activities between patients and control subjects. In neutral conditions, pH 6.0, the PPT1 enzyme activities in NCL 1 patients showed rather higher residual activities and intermediate activities in heterozygotes in NCL 1, which was probably caused by mutated proteins in three cases with NCL 1 patients. TPP1 enzyme activities at neutral pH 6.5 to 7.0 in DBS and leukocytes/lymphocytes showed higher enzyme activities in NCL 2 patients and heterozygotes. The reason for the increases of neutral TPP1 enzyme activities at pH 6.5 to 7.0 in NCL 2 DBS and leukocytes/lymphocytes, is obscure, but possibly caused by secondary activation of neutral TPP1 enzyme due to the absence of the acidic form. Interestingly, TPP1 activity in serum only consisted of a neutral form, no acidic form, and was not deficient in any NCL 2 patient. Therefore, we can diagnose NCL 1 patients by plasma/serum enzyme assay of PPT1, but not diagnose NCL 2 by serum TPP1 enzyme assay. A pilot study of newborn screening of NCL 1 and 2 has been established by more than 1000 newborn DBS assays. Using this assay system, we will be able to perform newborn screening of NCL 1 and 2 by DBS. PMID- 29599077 TI - Delineating the global challenges of hepatitis B virus infection. PMID- 29599079 TI - Efficient In Vivo Liver-Directed Gene Editing Using CRISPR/Cas9. AB - In vivo tissue-specific genome editing at the desired loci is still a challenge. Here, we report that AAV9-delivery of truncated guide RNAs (gRNAs) and Cas9 under the control of a computationally designed hepatocyte-specific promoter lead to liver-specific and sequence-specific targeting in the mouse factor IX (F9) gene. The efficiency of in vivo targeting was assessed by T7E1 assays, site-specific Sanger sequencing, and deep sequencing of on-target and putative off-target sites. Though AAV9 transduction was apparent in multiple tissues and organs, Cas9 expression was restricted mainly to the liver, with only minimal or no expression in other non-hepatic tissues. Consequently, the insertions and deletion (indel) frequency was robust in the liver (up to 50%) in the desired target loci of the F9 gene, with no evidence of targeting in other organs or other putative off target sites. This resulted in a substantial loss of FIX activity and the emergence of a bleeding phenotype, consistent with hemophilia B. The in vivo efficacy of the truncated gRNA was as high as that of full-length gRNA. Cas9 expression was transient in neonates, representing an attractive "hit-and-run" paradigm. Our findings have potentially broad implications for somatic gene targeting in the liver using the CRISPR/Cas9 platform. PMID- 29599080 TI - Exosomes from Endothelial Progenitor Cells Improve the Outcome of a Murine Model of Sepsis. AB - Microvascular dysfunction leads to multi-organ failure and mortality in sepsis. Our previous studies demonstrated that administration of exogenous endothelial progenitor cells (EPCs) confers protection in sepsis as evidenced by reduced vascular leakage, improved organ function, and increased survival. We hypothesize that EPCs protect the microvasculature through the exosomes-mediated transfer of microRNAs (miRNAs). Mice were rendered septic by cecal ligation and puncture (CLP), and EPC exosomes were administered intravenously at 4 hr after CLP. EPC exosomes treatment improved survival, suppressing lung and renal vascular leakage, and reducing liver and kidney dysfunction in septic mice. EPC exosomes attenuated sepsis-induced increases in plasma levels of cytokines and chemokine. Moreover, we determined miRNA contents of EPC exosomes with next-generation sequencing and found abundant miR-126-3p and 5p. We demonstrated that exosomal miR-126-5p and 3p suppressed LPS-induced high mobility group box 1 (HMGB1) and vascular cell adhesion molecule 1 (VCAM1) levels, respectively, in human microvascular endothelial cells (HMVECs). Inhibition of microRNA-126-5p and 3p through transfection with microRNA-126-5p and 3p inhibitors abrogated the beneficial effect of EPC exosomes. The inhibition of exosomal microRNA-126 failed to block LPS-induced increase in HMGB1 and VCAM1 protein levels in HMVECs and negated the protective effect of exosomes on sepsis survival. Thus, EPC exosomes prevent microvascular dysfunction and improve sepsis outcomes potentially through the delivery of miR-126. PMID- 29599078 TI - Global prevalence, treatment, and prevention of hepatitis B virus infection in 2016: a modelling study. AB - BACKGROUND: The 69th World Health Assembly approved the Global Health Sector Strategy to eliminate viral hepatitis by 2030. Although no virological cure exists for hepatitis B virus (HBV) infection, existing therapies to control viral replication and prophylaxis to minimise mother-to-child transmission make elimination of HBV feasible. We aimed to estimate the national, regional, and global prevalence of HBsAg in the general population and in the population aged 5 years in 2016, as well as coverage of prophylaxis, diagnosis, and treatment. METHODS: In this modelling study, we used a Delphi process that included a literature review in PubMed and Embase, followed by interviews with experts, to quantify the historical epidemiology of HBV infection. We then used a dynamic HBV transmission and progression model to estimate the country-level and regional level prevalence of HBsAg in 2016 and the effect of prophylaxis and treatment on disease burden. FINDINGS: We developed models for 120 countries, 78 of which were populated with data approved by experts. Using these models, we estimated that the global prevalence of HBsAg in 2016 was 3.9% (95% uncertainty interval [UI] 3.4-4.6), corresponding to 291 992 000 (251 513 000-341 114 000) infections. Of these infections, around 29 million (10%) were diagnosed, and only 4.8 million (5%) of 94 million individuals eligible for treatment actually received antiviral therapy. Around 1.8 (1.6-2.2) million infections were in children aged 5 years, with a prevalence of 1.4% (1.2-1.6). We estimated that 87% of infants had received the three-dose HBV vaccination in the first year of life, 46% had received timely birth-dose vaccination, and 13% had received hepatitis B immunoglobulin along with the full vaccination regimen. Less than 1% of mothers with a high viral load had received antiviral therapy to reduce mother-to-child transmission. INTERPRETATION: Our estimate of HBV prevalence in 2016 differs from previous studies, potentially because we took into account the effect of infant prophylaxis and early childhood vaccination, as well as changing prevalence over time. Although some regions are well on their way to meeting prophylaxis and prevalence targets, all regions must substantially scale-up access to diagnosis and treatment to meet the global targets.

AB - PURPOSE: The International Atomic Energy Agency (IAEA) through a Coordinated Research Project on "Enhancing Capacity for Early Detection and Diagnosis of Breast Cancer through Imaging", brought together a group of mammography radiologists, medical physicists and radiographers; to investigate current practices and improve procedures for the early detection of breast cancer by strengthening both the clinical and medical physics components. This paper addresses the medical physics component. METHODS: The countries that participated in the CRP were Bosnia and Herzegovina, Costa Rica, Egypt, India, Kenya, the Frmr. Yug. Rep. of Macedonia, Mexico, Nigeria, Pakistan, Philippines, Slovenia, Turkey, Uganda, United Kingdom and Zambia. Ten institutions participated using IAEA quality control protocols in 9 digital and 3 analogue mammography equipment. A spreadsheet for data collection was generated and distributed. Evaluation of image quality was done using TOR MAX and DMAM2 Gold phantoms. RESULTS: QC results for analogue equipment showed satisfactory results. QC tests performed on digital systems showed that improvements needed to be implemented, especially in thickness accuracy, signal difference to noise ratio (SDNR) values for achievable levels, uniformity and modulation transfer function (MTF). Mean glandular dose (MGD) was below international recommended levels for patient radiation protection. Evaluation of image quality by phantoms also indicated the need for improvement. CONCLUSIONS: Common activities facilitated improvement in mammography practice, including training of medical physicists in QC programs and infrastructure was improved and strengthened; networking among medical physicists and radiologists took place and was maintained over time. IAEA QC protocols provided a uniformed approach to QC measurements.

AB - The congenital dyserythropoietic anemias are a heterogeneous group of disorders characterized by anemia and ineffective erythropoiesis. Congenital dyserythropoietic anemia type I (CDA1) can present in utero with hydrops fetalis, but more often it presents in childhood or adulthood with moderate macrocytic anemia, jaundice, and progressive iron-overload. CDA1 is inherited in an autosomal recessive manner, with biallelic pathogenic variants in CDAN1 or C15orf41. This case report documents a severe fetal presentation of CDA1 where we identified two novel compound heterozygous mutations in CDAN1 and describes the associated pathologic findings and levels of iron-regulatory proteins hepcidin, erythroferrone, and GDF15. PMID- 29599086 TI - Evaluation of Mycoplasma gallisepticum (MG) ts-304 vaccine as a live attenuated vaccine in turkeys. AB - Mycoplasma gallisepticum (MG) is an important pathogen of poultry worldwide that causes chronic respiratory disease (CRD) in chickens and infectious sinusitis in turkeys. Vaxsafe MG (strain ts-11) is a live attenuated temperature sensitive vaccine that has been proven to be effective in controlling CRD in chickens, but it is not efficacious in turkeys. The gapA gene, which encodes a mature cytadhesin protein with a molecular weight of approximately 105 kDa, is not expressed in strain ts-11 because a 20 base pair reiterated sequence introduces a frame shift and causes premature truncation of the translated peptide. A GapA positive clone, MG ts-304, isolated from strain ts-11 has been shown to have enhanced efficacy in chickens. Here we describe studies we conducted to assess the safety and efficacy of the MG ts-304 vaccine candidate in turkeys. We found that MG ts-304 was able to colonise the trachea of 3-week-old turkeys and was safe, even at a tenfold overdose, inducing no adverse clinical signs of respiratory disease or significant gross lesions in the respiratory tract (air sacs or trachea), and was poorly transmissible to in-contact birds. We also showed that it was efficacious when administered to 3-week-old turkeys, inducing protective immunity against challenge with the M.gallisepticum wild-type strain Ap3AS. MG ts-304 is therefore a promising live attenuated vaccine candidate for use in turkeys. PMID- 29599087 TI - A novel method for strict intranasal delivery of non-replicating RSV vaccines in cotton rats and non-human primates. AB - Respiratory syncytial virus (RSV) is the most common viral cause of bronchiolitis and pneumonia in children twelve months of age or younger and a significant cause of lower respiratory disease in older adults. As various clinical and preclinical candidates advance, cotton rats (Sigmodon hispidus) and non-human primates (NHP) continue to play a valuable role in RSV vaccine development, since both animals are semi-permissive to human RSV (HRSV). However, appropriate utilization of the models is critical to avoid mis-interpretation of the preclinical findings. Using a multimodality imaging approach; a fluorescence based optical imaging technique for the cotton rat and a nuclear medicine based positron emission tomography (PET) imaging technique for monkeys, we demonstrate that many common practices for intranasal immunization in both species result in inoculum delivery to the lower respiratory tract, which can result in poor translation of outcomes from the preclinical to the clinical setting. Using these technologies we define a method to limit the distribution of intranasally administered vaccines solely to the upper airway of each species, which includes volume restrictions in combination with injectable anesthesia. We show using our newly defined methods for strict intranasal immunization that these methods impact the immune responses and efficacy observed when compared to vaccination methods resulting in distribution to both the upper and lower respiratory tracts. These data emphasize the importance of well-characterized immunization methods in the preclinical assessment of intranasally delivered vaccine candidates. PMID- 29599088 TI - A single vaccination with non-replicating MVA at birth induces both immediate and long-term protective immune responses. AB - Newborns are considered difficult to protect against infections shortly after birth, due to their ineffective immune system that shows quantitative and qualitative differences compared to adults. However, here we show that a single vaccination of mice at birth with a replication-deficient live vaccine Modified Vaccinia Ankara [MVA] efficiently induces antigen-specific B- and T-cells that fully protect against a lethal Ectromelia virus challenge. Protection was induced within 2 weeks and using genetically modified mice we show that this protection was mainly T-cell dependent. Persisting immunological T-cell memory and neutralizing antibodies were obtained with the single vaccination. Thus, MVA administered as early as at birth induced immediate and long-term protection against an otherwise fatal disease and appears attractive as a new generation smallpox vaccine that is effective also in children. Moreover, it may have the potential to serve as platform for childhood vaccines as indicated by measles specific T- and B-cell responses induced in newborn mice vaccinated with recombinant MVA expressing measles antigens. PMID- 29599089 TI - Cancer-salient messaging for Human Papillomavirus vaccine uptake: A randomized controlled trial. AB - BACKGROUND AND OBJECTIVES: Vaccination with Human Papillomavirus (HPV) vaccine is recommended for 11-12 years-old, but uptake is suboptimal. Current messaging focuses on HPV infection transmission and prevention. Parents and providers are often uncomfortable discussing sexual practices of adolescents, contributing to the delay/refusal of vaccine. We created a cervical cancer-salient message encouraging HPV vaccination, emphasizing disease salience and disease threat, while promoting self-efficacy. We hypothesized this message would have greater effects on vaccine confidence and intent to vaccinate compared to Centers for Disease Control and Prevention (CDC) and non-vaccine control messages. METHODS: A 3-arm randomized trial was conducted. Parents of girls aged 9-17 were eligible for the study. We measured participants' vaccine confidence and intent to vaccinate at baseline and post intervention message. Recruitment and surveys were administered online through Amazon Mechanical Turk. RESULTS: 762 participants completed both surveys. We saw modest increases in vaccine confidence when comparing cervical cancer arm and control arm, and CDC arm and control arm; estimates were not statistically significant. The odds of reporting intent to vaccinate among the cervical cancer message arm were 1.13 times the odds of reporting intent to vaccinate in the control arm (95% CI: 0.30. 4.29). Intent to vaccinate was also not statistically significantly different between CDC message arm and control arm (OR = 1.25, 95%CI: 0.66, 2.37). CONCLUSION: Neither message had effect on intent to vaccinate, highlighting need for research to identify successful messaging strategies for HPV. Exploratory analyses suggest among parents with 'Low' vaccine confidence at baseline, the cervical cancer framed message may be more effective in changing intention than the CDC message or non vaccine control. Future work should target groups with 'Low' or 'Medium' vaccine confidence at baseline - they may be more amenable to change, and more receptive to disease-salient messaging. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov, Reference #: NCT03002324. PMID- 29599090 TI - Intranasal but not subcutaneous vaccination with LaAg allows rapid expansion of protective immunity against cutaneous leishmaniasis. AB - Mucosal but not parenteral vaccination with whole Leishmania amazonensis promastigotes antigens (LaAg) is known to increase host resistance to infection by an as yet unknown immune mechanism. Since early immune responses are critical for infection establishment, in the present study the differential responses elicited by subcutaneous (s.c.) and intranasal (i.n.) vaccination with LaAg were investigated during the initial stages of infection. For that, BALB/c mice were given two LaAg doses by i.n. or s.c. route prior to L. amazonensis infection in the footpad. It was found that mucosal vaccination prevented both T helper (Th) 2 associated cutaneous hypersensitivity and local interleukin (IL)-4 production in the first days after parasite challenge in the footpad. That was accompanied by increased Th1 (T-bet and IL-12) and Treg (Foxp3 and IL-10) transcription factor and cytokine expression in the lesion draining lymph nodes. In contrast, s.c. LaAg predominantly led to higher Th2 (GATA3) and transforming growth factor (TGF) beta expression. Prior i.n. vaccination was able to prevent the disease exacerbating effect of s.c. vaccination. Although both CD4+ and CD8+ T cells were transiently increased in the cervical lymph nodes (cLN), the numbers of CD4+Foxp3+ regulatory T (Treg) cells decreased within 48 h of i.n. vaccination as compared to non-vaccinated mice. Adoptive transfer of such cLN cells conferred increased resistance to infected mice, mimicking the effect of i.n. vaccination. Altogether, these data indicate that i.n. vaccination with LaAg may prevent early peripheral expansion of detrimental cells normally elicited by active infection or s.c. vaccination, thus allowing full expansion of protective responses. PMID- 29599091 TI - Waist-height ratio in children of 7 to 11 years with high weight at birth and its relationship with gender, age and diet. AB - INTRODUCTION: Obesity (OB), considered as one of the Non-Transmissible Chronic Diseases, has as its fundamental characteristics that of being prevalent at a global level, increasing in number, affecting developed and developing countries, affecting both genders, and all ages and social groups. OBJECTIVE: To identify if high birth weight is a predictive factor (risk factor) for abdominal obesity in children 7 to 11 years old, and its relationship to gender, age and diet. METHOD: A case-control descriptive study was carried out with children born between January 1992 and December 1995, in order to identify early risk factors (atherosclerotic accelerators) such as abdominal obesity in children aged 7 to 11, and who have a history of macrosomia or high birth weight, as well as their relationship with gender, age and diet. RESULTS: It was observed that the waist/height value was normal in 60.8% of the study group and in 64.00% in the control group. The difference between groups, gender, and age was not significant (P=.6859). As regards the diet in the study group (macrosomic), there was no significant association between the type of diet and waist circumference/height values, with an chi2=0.223 and P=.6373 (not significant). In the control group (with normal weight at birth), it was found that there is a significant statistical association between the type of diet and waist circumference/height values. This means that it can be stated, with 95% reliability, that the type of diet is associated with waist/height values. CONCLUSIONS: High birth weight is not a predictive factor (risk factor) for abdominal obesity (increased waist/height index). Gender and age are independent for abdominal obesity (macrosomic and normal weight at birth). The diet in high birth weight children is not related to the index waist-height index, which is not the case in those born with normal weight under the same conditions. The marked increase in abdominal obesity (Waist/height index) in children between 7 and 11 years old in both groups is worrying. PMID- 29599092 TI - Cardiorenal syndrome as predictor of in-hospital mortality in ST-segment elevation myocardial infarction. AB - INTRODUCTION: Cardiorenal syndrome includes numerous conditions affecting the heart and kidney, and is a strong predictor of cardiovascular mortality. METHOD: An analysis was performed on 157 consecutive patients admitted to the Coronary Care Unit of the Camilo Cienfuegos Hospital due to an ST-segment elevation myocardial infarction and heart failure, from January 2013 to December 2016. An analysis was made of the presence of cardiorenal syndrome and its relationship with epidemiological, clinical, and analytical variables, as well as complementary explorations. The relationship between cardiorenal syndrome and in hospital mortality was assessed using binary logistical regression. RESULTS: A total of 52 (33.1%) patients had a cardiorenal syndrome. The haemoglobin level was lower in the group of patients with cardiorenal syndrome (117.2 +/- 15.3 vs. 123.3 +/- 15.1, P = .019), and in left ventricular ejection fraction (34.8 +/- 8 vs. 43.2 +/- 10.8). A positive correlation was found between the Killip class and the increase in serum creatinine after 48 h. The serum creatinine was associated with left ventricular ejection fraction (r = 0.166; P = .038). The multivariate analysis showed that cardiorenal syndrome was an independent predictor of in hospital mortality when adjusted for a history of ischaemic heart disease, diabetes mellitus status, atrial fibrillation, ventricular arrhythmias, left ventricular ejection fraction, age and systolic blood pressure. CONCLUSIONS: The presence of cardiorenal syndrome has an influence on the prognosis of patients who suffer a cardiorenal syndrome. Its detection could be useful in the risk stratification. PMID- 29599093 TI - Aberrant within- and between-network connectivity of the mirror neuron system network and the mentalizing network in first episode psychosis. AB - INTRODUCTION: It has been suggested that the mentalizing network and the mirror neuron system network support important social cognitive processes that are impaired in schizophrenia. However, the integrity and interaction of these two networks have not been sufficiently studied, and their effects on social cognition in schizophrenia remain unclear. METHODS: Our study included 26 first episode psychosis (FEP) patients and 26 healthy controls. We utilized resting state functional connectivity to examine the a priori-defined mirror neuron system network and the mentalizing network and to assess the within- and between network connectivities of the networks in FEP patients. We also assessed the correlation between resting-state functional connectivity measures and theory of mind performance. RESULTS: FEP patients showed altered within-network connectivity of the mirror neuron system network, and aberrant between-network connectivity between the mirror neuron system network and the mentalizing network. The within-network connectivity of the mirror neuron system network was noticeably correlated with theory of mind task performance in FEP patients. CONCLUSION: The integrity and interaction of the mirror neuron system network and the mentalizing network may be altered during the early stages of psychosis. Additionally, this study suggests that alterations in the integrity of the mirror neuron system network are highly related to deficient theory of mind in schizophrenia, and this problem would be present from the early stage of psychosis. PMID- 29599094 TI - Replication of GWAS identified miR-137 and its target gene polymorphisms in Schizophrenia of South Indian population and meta-analysis with Psychiatric Genomics Consortium. AB - Schizophrenia is a complex psychiatric disorder involving multiple genes each contributing a small risk. Genome-wide association studies (GWASs) have identified hundreds of risk loci for schizophrenia including miR-137, a miRNA shown to be involved in neuronal development. Several genes regulated by miR-137 were also reported as top risk genes associated with schizophrenia and has been hypothesised that the dysregulation of miR-137 and its target could be involved in the aetiology of schizophrenia. Here, we replicated the four European GWAS hits, miR-137-rs1625579 and three of its validated target gene loci SNPs (ZNF804a rs1344706, CACNA1C-rs4765905 and TCF4-rs9960767) by genotyping in 2074 samples (schizophrenia cases-1005; controls-1069) from South Indian Population. In this study, only the CACNA1C rs4765905 showed a significant association (OR=1.24, p=0.006). Three SNPs (rs1625579, rs1344706 and rs4765905) showed a consistent direction of effect with previous studies and the polygenic risk score constructed using the weighted sum of these three SNPs showed a significant association with Schizophrenia in this population (OR=3.78, p=0.005). Further, we carried out meta-analysis combining our results with the Psychiatric Genomics Consortium (PGC2) data and observed a considerable increase in GWAS significance. PMID- 29599095 TI - Reported Resuscitation of a Hypothermic Avalanche Victim With Assisted Ventilation in 1939. AB - We present a historical case of a 12-year-old boy who survived a reported avalanche burial in 1939 in the Upper Peninsula of Michigan. The boy was completely buried for at least 3 h, head down, at a depth of about 1 m. He was extricated without signs of life and likely hypothermic by his father, who took him to his home. There, the father performed assisted ventilation for 3 hours using the Schafer method, a historical method of artificial ventilation, without any specific rewarming efforts. The boy recovered neurologically intact. This case illustrates the importance of attempting resuscitation, possibly prolonged, of victims of hypothermia, even those who are apparently dead. PMID- 29599096 TI - Antithrombotic therapy trends in non-valvular atrial fibrillation patients undergoing percutaneous coronary stent implantation: Results from a survey among fellows at the Japanese College of Cardiology. AB - BACKGROUND: Antithrombotic therapy with oral anticoagulants (OAC) in patients with atrial fibrillation (AF) after stent implantation, where dual antiplatelet therapy (DAPT) is also recommended, is not established. Antithrombotic therapies prescribed vary widely among cardiologists and may change year by year, according to the accumulation of new evidence. METHODS: A questionnaire-based survey concerning the antithrombotic therapy prescribed for OAC-treated AF patients who underwent stent implantation was conducted from 2014 to 2016. The survey was completed by the Fellows of the Japanese College of Cardiology (FJCC). RESULTS: The questionnaire was sent to 1023 fellows in 2014, a total of 1057 fellows in 2015, and 1073 fellows in 2016; 268 (26%), 418 (40%), and 416 (39%) answers were obtained, respectively. The duration of DAPT did not change in patients with bare metal stents; however, it tended to become shorter with the use of the drug eluting stent (DES). Significant shortening of DAPT duration was observed with DES for stable coronary artery disease from 2015 to 2016. A similar tendency was observed for acute coronary syndrome (ACS); however, this was not significant between 2015 and 2016. A shorter duration of DAPT is preferred by electrophysiologists rather than by interventionalists and general cardiologists. OAC monotherapy is not popular one year after stent implantation, although the prevalence of its use increased year by year. Aspirin and thienopyridines are used equally as a single antiplatelet in DAPT, and clopidogrel is also a popular agent. The prevalence of direct OAC use increased year by year. CONCLUSIONS: The questionnaire showed variation in antithrombotic therapy used for OAC-treated AF patients after stenting, and how it changes year by year. Although the duration of DAPT tended to shorten, variations are still observed, i.e. the selection of a single antiplatelet or OAC. PMID- 29599097 TI - High-sensitivity cardiac troponin T and prognosis in patients with ST-segment elevation myocardial infarction. AB - BACKGROUND: Evidence on the use of high-sensitivity cardiac troponins (hs-cTn) to risk-stratify patients with ST-segment elevation myocardial infarction (STEMI) is limited. METHODS: We assessed the prognostic value of preprocedural (admission) and peak postprocedural hs-cTnT in 818 patients with STEMI treated with primary percutaneous coronary intervention (PPCI). Preprocedural and peak postprocedural hs-cTnT was measured. The primary outcome was 3-year all-cause mortality. RESULTS: The median values of preprocedural and peak postprocedural hs-cTnT were 153ng/L and 1980ng/L. Overall, 134 patients died during the follow-up. There were 85 deaths in patients with preprocedural hs-cTnT >median value and 49 deaths in patients with preprocedural hs-cTnT <=median value [Kaplan-Meier estimates of mortality, 22.2% and 13.5%; unadjusted hazard ratio (HR)=1.88, 95% confidence interval (CI) 1.32-2.67, p<0.001]. According to peak postprocedural hs-cTnT, there were 84 deaths in patients with postprocedural hs-cTnT >median value and 50 deaths in patients with postprocedural hs-cTnT <=median value [Kaplan-Meier estimates of mortality, 22.3% and 13.4%; unadjusted HR=1.82 (1.28-2.59), p<0.001]. After adjustment, preprocedural [adjusted HR=1.08 (1.03-1.12), p<0.001] and peak postprocedural hs-cTnT value [adjusted HR=1.06 (1.04-1.08), p<0.001] were independently associated with 3-year mortality (with risk estimates calculated per 70*99th upper reference limit of hs-cTnT). The C statistic of multivariable model increased from 0.868 (0.841-0.895) to 0.872 (0.845-0.898) after incorporation of preprocedural hs-cTnT (p=0.050) and to 0.874 (0.846-0.899) after incorporation of the postprocedural hs-cTnT into the model (p=0.035). CONCLUSIONS: In conclusion, admission or peak postprocedural hs-cTnT is independently associated with the risk for 3-year mortality in patients with STEMI undergoing PPCI. PMID- 29599098 TI - The Selvester QRS score as a predictor of cardiac events in nonischemic dilated cardiomyopathy. PMID- 29599099 TI - Predictive value of acute kidney injury for major adverse cardiovascular events following tricuspid annuloplasty: A comparison of three consensus criteria. AB - BACKGROUND: Tricuspid annuloplasty (TA) is increasingly being performed, but the clinical outcome is unsatisfactory. Acute kidney injury (AKI) is a common complication following cardiac surgery and predicts outcome. Nonetheless the occurrence rate and prognostic value of AKI after TA are unclear. METHODS: This study reviewed 339 consecutive patients (age 65+/-11 years; male 42%) who underwent TA. The incidence of AKI was defined according to risk/injury/failure/loss/end stage (RIFLE), acute kidney injury network (AKIN), and kidney disease improving global outcomes (KDIGO) criteria, respectively. Major adverse cardiovascular events (MACE) was defined as death, heart failure, stroke, and myocardial infarction (MI). The influence of AKI on MACE was evaluated as a short-term outcome and outcome beyond 30 days. RESULTS: The incidence of AKI, defined according to RIFLE, AKIN, and KDIGO was 57%, 52%, and 53%, respectively. MACE occurred in 94 cases (21 deaths, 63 heart failure requiring hospitalization, 7 stroke, and 3 MI). For short-term outcome, AKI defined by all three scoring systems was independently associated with MACE and death (p<0.01 for both), but not heart failure, stroke, or MI. For outcome beyond 30 days, AKI by all three criteria was associated with MACE and heart failure. Only AKI by AKIN and KDIGO, but not RIFLE, was independently associated with death. CONCLUSION: Our data suggest AKI affects over half of all patients who undergo TA, and has a major and long-lasting impact on survival, MACE, and heart failure. Use of AKIN and KDIGO is more useful than the RIFLE criteria when determining the prognostic value of AKI for mortality beyond 30 days.

AB - INTRODUCTION: Nutritional intake during early ages has been associated to disease onset later in life. This study aimed to assess dietary intake in Spanish university students of health sciences as compared to national recommended dietary intakes (DRIs). METHODS: A cross-sectional study was conducted including 585 university students of health sciences aged 18-25 years. Dietary intake was assessed using a 72-h diet recall. A control group was selected from Spanish National Dietary Intake Survey (ENIDE) data. RESULTS: Intake of energy, protein, fat, fatty acids, and cholesterol was significantly lower (p<0.001) in university students compared to controls, while fiber intake showed the opposite trend (p<0.001). Total fat and carbohydrate intake was consistent with recommendations, but protein intake was lower than recommended. Intake of saturated fatty acids (SFAs) was markedly higher than nutrition goals, while intake of monounsaturated fatty acids (MUFAs) was lower. Both students and the reference control group did not reach the optimal dietary intake of iodine and vitamins D and E, while sodium intake was excessive in both groups. CONCLUSIONS: Dietary habits of university students were mainly characterized by low intakes of energy, protein, fats, fatty acids, and cholesterol, and high intake of fiber as compared to the general population. Intake of iodine and vitamins D and E was low, while sodium intake was excessive in both university students and the general population. Dietary interventions should be considered to prevent nutritional deficiencies and to ensure a balanced diet. PMID- 29599103 TI - Assessment of structural valve deterioration of transcatheter aortic bioprosthetic balloon-expandable valves using the new European consensus definition. AB - AIMS: Durability of transcatheter aortic bioprosthetic valves remains a major issue. Standardised definitions of deterioration and failure of bioprosthetic valves have recently been proposed. The aim of this study was to assess structural transcatheter valve deterioration (SVD) and bioprosthetic valve failure (BVF) using these new definitions. METHODS AND RESULTS: All TAVI patients implanted up to September 2012 with a minimal theoretical five-year follow-up were included. Systematic clinical and echocardiographic follow-up was performed annually. New standardised definitions were used to assess durability of transcatheter aortic bioprosthetic valves. From 2002 to 2012, 378 patients were included. Mean age and logistic EuroSCORE were 83.3+/-6.8 years and 22.8+/-13.1%. Thirty-day mortality was 13.2%. Nine patients had SVD including two severe forms and two patients had definite late BVF. The incidence of SVD and BVF at eight years was 3.2% (95% CI: 1.45-6.11) and 0.58% (95% CI: 0.15-2.75), respectively. CONCLUSIONS: Even though limited by the poor survival of the very high risk/compassionate early population, our data do not demonstrate any alarm concerning transcatheter aortic valve durability. Careful prospective assessment in younger and lower-risk patients and comparison with surgical bioprosthetic valves are required for further assessment of the long-term durability of transcatheter valves. PMID- 29599104 TI - Physical Trauma Patients with Symptoms of an Acute and Posttraumatic Stress Disorder: Protocol for an Observational Prospective Cohort Study. AB - BACKGROUND: Injury, medical treatment, and rehabilitation can have major impacts on patients' wellbeing. About 25-33% of the patients experience an acute stress disorder (ASD) or a posttraumatic stress disorder (PTSD) after injury. ASD is a relatively new diagnosis. Therefore, knowledge about patients' experiences, the course of ASD and PTSD, and who is at risk for developing ASD or PTSD is lacking. OBJECTIVE: The aims of this multi-method study are to explore patients' experiences with injury (and their care) using a focus group study. Then, in the observational study, different courses of ASD, PTSD, and quality of life will be examined. In addition, this study will examine if these courses could be characterized by socio-demographic, clinical, and psychological variables. Consequently, a risk profile will be developed to determine which patients are at risk for developing ASD or PTSD during the 12 months after injury. METHODS: Trauma patients treated in the shock room (in 2015) of the Elisabeth-TweeSteden Hospital will share their experiences with injury in the focus group study. Open, axial, and selective coding will be used to analyze the data. Concerning the observational study, patients treated in the shock room (during 2016 and 2017, Elisabeth-TweeSteden Hospital and Erasmus Medical Centre) will be asked to participate. The inclusion period is 12 months. Participants will complete the Impact of Event Scale-Revised, MINI-plus, the Hospital Anxiety and Depression Scale, and the World Health Organization Quality of Life-BREF after inclusion and at 3, 6, 9, and 12 months after injury. The NEO-Five Factor Inventory and the State-Trait Anxiety Inventory-Trait are completed after inclusion only. Repeated measures of latent class analysis and linear mixed models will be used to examine the research aims. RESULTS: This project was funded in August 2015 by ZonMw. The results of the focus group study are expected in the first trimester of 2018. With regard to the observational study, recruitment is currently underway. Data collection will be completed in November 2018. The first results will be expected in the first trimester of 2019. CONCLUSIONS: This is the first multi-method study in trauma patients that examines patients' experiences (qualitative design) as well as psychological disorders (observational prospective). This study will contribute to necessary information on psychological consequences after injury. Moreover, it provides knowledge about which patients to include in future psychological intervention research. Finally, awareness in clinicians about the psychological consequences can be created, so they are able to act more effectively to provide patient-oriented care.

PMID- 29599105 TI - Participants' Perceptions on the Use of Wearable Devices to Reduce Sitting Time: Qualitative Analysis. AB - BACKGROUND: Recent epidemiological evidence indicates that, on average, people are sedentary for approximately 7.7 hours per day. There are deleterious effects of prolonged sedentary behavior that are separate from participation in physical activity and include increased risk of weight gain, cancer, metabolic syndrome, diabetes, and heart disease. Previous trials have used wearable devices to increase physical activity in studies; however, additional research is needed to fully understand how this technology can be used to reduce sitting time. OBJECTIVE: The purpose of this study was to explore the potential of wearable devices as an intervention tool in a larger sedentary behavior study through a general inductive and deductive analysis of focus group discussions. METHODS: We conducted four focus groups with 15 participants to discuss 7 different wearable devices with sedentary behavior capabilities. Participants recruited for the focus groups had previously participated in a pilot intervention targeting sedentary behavior over a 3-week period and were knowledgeable about the challenges of reducing sitting time. During the focus groups, participants commented on the wearability, functionality, and feedback mechanism of each device and then identified their two favorite and two least favorite devices. Finally, participants designed and described their ideal or dream wearable device. Two researchers, who have expertise analyzing qualitative data, coded and analyzed the data from the focus groups. A thematic analysis approach using Dedoose software (SocioCultural Research Consultants, LLC version 7.5.9) guided the organization of themes that reflected participants' perspectives. RESULTS: Analysis resulted in 14 codes that we grouped into themes. Three themes emerged from our data: (1) features of the device, (2) data the device collected, and (3) how data are displayed. CONCLUSIONS: Current wearable devices for increasing physical activity are insufficient to intervene on sitting time. This was especially evident when participants voted, as several participants reported using a "process of elimination" as opposed to choosing favorites because none of the devices were ideal for reducing sitting time. To overcome the limitations in current devices, future wearable devices designed to reduce sitting time should include the following features: waterproof, long battery life, accuracy in measuring sitting time, real time feedback on progress toward sitting reduction goals, and flexible options for prompts to take breaks from sitting. PMID- 29599106 TI - A Web- and Mobile-Based Map of Mental Health Resources for Postsecondary Students (Thought Spot): Protocol for an Economic Evaluation. AB - BACKGROUND: Youth demonstrate a low propensity to seek help for mental health issues and exhibit low use of health services despite the high prevalence of mental health challenges in this population. Research has found that delivering interventions via the internet and mobile devices is an effective way to reach youth. Thought Spot, a Web- and mobile-based map, was developed to help transition-aged youth in postsecondary settings overcome barriers to help seeking, thereby reducing the economic burden associated with untreated mental health issues. OBJECTIVE: This paper presents the protocol for an economic evaluation that will be conducted in conjunction with a randomized controlled trial (RCT) to evaluate the effectiveness and cost of Thought Spot compared with usual care in terms of self-efficacy for mental health help-seeking among postsecondary students. METHODS: A partially blinded RCT will be conducted to assess the impact of Thought Spot on the self-efficacy of students for mental health help-seeking. Students from 3 postsecondary institutions in Ontario, Canada will be randomly allocated to 1 of 2 intervention groups (resource pamphlet or Thought Spot) for 6 months. The economic evaluation will focus on the perspective of postsecondary institutions or other organizations interested in using Thought Spot. Costs and resources for operating and maintaining the platform will be reported and compared with the costs and resource needs associated with usual care. The primary outcome will be change in help-seeking intentions, measured using the General Help-Seeking Questionnaire. The cost effectiveness of the intervention will be determined by calculating the incremental cost-effectiveness ratio, which will then be compared with willingness to pay. RESULTS: The RCT is scheduled to begin in February 2018 and will run for 6 months, after which the economic evaluation will be completed. CONCLUSIONS: We expect to demonstrate that Thought Spot is a cost-effective way to improve help-seeking intentions and encourage help-seeking behavior among postsecondary students. The findings of this study will help inform postsecondary institutions when they are allocating resources for mental health initiatives.

PMID- 29599107 TI - Growth Dynamics of Patient-Provider Internet Communication: Trend Analysis Using the Health Information National Trends Survey (2003 to 2013). AB - BACKGROUND: Communication is key in chronic disease management, and the internet has altered the manner in which patients and providers can exchange information. Adoption of secure messaging differs among patients due to the digital divide that keeps some populations from having effective access to online resources. OBJECTIVE: This study aimed to examine the current state of online patient provider communication, exploring trends over time in the use of online patient provider communication tools. METHODS: A 3-part analytic process was used to study the following: (1) reanalysis, (2) close replication across years, and (3) trend analysis extension. During the reanalysis stage, the publicly available Health Information National Trends Survey (HINTS) 1 and 2 data were used with the goal of identifying the precise analytic methodology used in a prior study, published in 2007. The original analysis was extended to add 3 additional data years (ie, 2008, 2011, and 2013) using the original analytical approach with the purpose of identifying trends over time. Multivariate logistic regression was used to analyze pooled data across all years, with year as an added predictor, in addition to a model for each individual data year. RESULTS: The odds of internet users to communicate online with health care providers was significantly and increasingly higher year-over-year, starting in 2003 (2005: odds ratio [OR] 1.31, 95% CI 1.03-1.68; 2008: OR 2.14, 95% CI 1.76-2.59; 2011: OR 2.92, 95% CI 2.33 3.66; and 2013: OR 5.77; 95% CI 4.62-7.20). Statistically significant socio economic factors found to be associated with internet users communicating online with providers included age, having health insurance, having a history of cancer, and living in an urban area of residence. CONCLUSIONS: The proportion of internet users communicating online with their health care providers has significantly increased since 2003. Although these trends are encouraging, access challenges still exist for some groups, potentially giving rise to a new set of health disparities related to communication. PMID- 29599108 TI - Lessons Learned From a Living Lab on the Broad Adoption of eHealth in Primary Health Care. AB - BACKGROUND: Electronic health (eHealth) solutions are considered to relieve current and future pressure on the sustainability of primary health care systems. However, evidence of the effectiveness of eHealth in daily practice is missing. Furthermore, eHealth solutions are often not implemented structurally after a pilot phase, even if successful during this phase. Although many studies on barriers and facilitators were published in recent years, eHealth implementation still progresses only slowly. To further unravel the slow implementation process in primary health care and accelerate the implementation of eHealth, a 3-year Living Lab project was set up. In the Living Lab, called eLabEL, patients, health care professionals, small- and medium-sized enterprises (SMEs), and research institutes collaborated to select and integrate fully mature eHealth technologies for implementation in primary health care. Seven primary health care centers, 10 SMEs, and 4 research institutes participated. OBJECTIVE: This viewpoint paper aims to show the process of adoption of eHealth in primary care from the perspective of different stakeholders in a qualitative way. We provide a real world view on how such a process occurs, including successes and failures related to the different perspectives. METHODS: Reflective and process-based notes from all meetings of the project partners, interview data, and data of focus groups were analyzed systematically using four theoretical models to study the adoption of eHealth in primary care. RESULTS: The results showed that large-scale implementation of eHealth depends on the efforts of and interaction and collaboration among 4 groups of stakeholders: patients, health care professionals, SMEs, and those responsible for health care policy (health care insurers and policy makers). These stakeholders are all acting within their own contexts and with their own values and expectations. We experienced that patients reported expected benefits regarding the use of eHealth for self-management purposes, and health care professionals stressed the potential benefits of eHealth and were interested in using eHealth to distinguish themselves from other care organizations. In addition, eHealth entrepreneurs valued the collaboration among SMEs as they were not big enough to enter the health care market on their own and valued the collaboration with research institutes. Furthermore, health care insurers and policy makers shared the ambition and need for the development and implementation of an integrated eHealth infrastructure. CONCLUSIONS: For optimal and sustainable use of eHealth, patients should be actively involved, primary health care professionals need to be reinforced in their management, entrepreneurs should work closely with health care professionals and patients, and the government needs to focus on new health care models stimulating innovations. Only when all these parties act together, starting in local communities with a small range of eHealth tools, the potential of eHealth will be enforced. PMID- 29599109 TI - Does Eating Chicken Feet With Pickled Peppers Cause Avian Influenza? Observational Case Study on Chinese Social Media During the Avian Influenza A (H7N9) Outbreak. AB - BACKGROUND: A hot topic on the relationship between a popular avian-origin food and avian influenza occurred on social media during the outbreak of the emerging avian influenza A (H7N9). The misinformation generated from this topic had caused great confusion and public concern. OBJECTIVE: Our goals were to analyze the trend and contents of the relevant posts during the outbreak. We also aimed to understand the characteristics of the misinformation and to provide suggestions to reduce public misconception on social media during the emerging disease outbreak. METHODS: The original microblog posts were collected from China's Sina Weibo and Tencent Weibo using a combination of keywords between April 1, 2013 and June 2, 2013. We analyzed the weekly and daily trend of the relevant posts. Content analyses were applied to categorize the posts into 4 types with unified sorting criteria. The posts' characteristics and geographic locations were also analyzed in each category. We conducted further analysis on the top 5 most popular misleading posts. RESULTS: A total of 1680 original microblog posts on the topic were retrieved and 341 (20.30%) of these posts were categorized as misleading messages. The number of relevant posts had not increased much during the first 2 weeks but rose to a high level in the next 2 weeks after the sudden increase in number of reported cases at the beginning of week 3. The posts under "misleading messages" occurred and increased from the beginning of week 3, but their daily posting number decreased when the daily number of posts under "refuting messages" outnumbered them. The microbloggers of the misleading posts had the lowest mean rank of followers and previous posts, but their posts had a highest mean rank of posts. The proportion of "misleading messages" in places with no reported cases was significantly higher than that in the epidemic areas (23.6% vs 13.8%). The popular misleading posts appeared to be short and consisted of personal narratives, which were easily disseminated on social media. CONCLUSIONS: Our findings suggested the importance of responding to common questions and misconceptions on social media platforms from the beginning of disease outbreaks. Authorities need to release clear and reliable information related to the popular topics early on. The microbloggers posting correct information should be empowered and their posts could be promoted to clarify false information. Equal importance should be attached to clarify misinformation in both the outbreak and nonoutbreak areas.

PMID- 29599112 TI - Clinical Monitoring of Well-Appearing Infants Born to Mothers With Chorioamnionitis. AB - BACKGROUND: The risk of early-onset sepsis is low in well-appearing late-preterm and term infants even in the setting of chorioamnionitis. The empirical antibiotic strategies for chorioamnionitis-exposed infants that are recommended by national guidelines result in antibiotic exposure for numerous well-appearing, uninfected infants. We aimed to reduce unnecessary antibiotic use in chorioamnionitis-exposed infants through the implementation of a treatment approach that focused on clinical presentation to determine the need for antibiotics. METHODS: Within a quality-improvement framework, a new treatment approach was implemented in March 2015. Well-appearing late-preterm and term infants who were exposed to chorioamnionitis were clinically monitored for at least 24 hours in a level II nursery; those who remained well appearing received no laboratory testing or antibiotics and were transferred to the level I nursery or discharged from the hospital. Newborns who became symptomatic were further evaluated and/or treated with antibiotics. Antibiotic use, laboratory testing, culture results, and clinical outcomes were collected. RESULTS: Among 277 well appearing, chorioamnionitis-exposed infants, 32 (11.6%) received antibiotics during the first 15 months of the quality-improvement initiative. No cases of culture result-positive early-onset sepsis occurred. No infant required intubation or inotropic support. Only 48 of 277 (17%) patients had sepsis laboratory testing. The implementation of the new approach was associated with a 55% reduction (95% confidence interval 40%-65%) in antibiotic exposure across all infants >=34 weeks' gestation born at our hospital. CONCLUSIONS: A management approach using clinical presentation to determine the need for antibiotics in chorioamnionitis-exposed infants was successful in reducing antibiotic exposure and was not associated with any clinically relevant delays in care or adverse outcomes.

AB - OBJECTIVES: To determine the prevalence of traumatic brain injuries in children who vomit after head injury and identify variables from published clinical decision rules (CDRs) that predict increased risk. METHODS: Secondary analysis of the Australasian Paediatric Head Injury Rule Study. Vomiting characteristics were assessed and correlated with CDR predictors and the presence of clinically important traumatic brain injury (ciTBI) or traumatic brain injury on computed tomography (TBI-CT). Isolated vomiting was defined as vomiting without other CDR predictors. RESULTS: Of the 19 920 children enrolled, 3389 (17.0%) had any vomiting, with 2446 (72.2%) >2 years of age. In 172 patients with ciTBI, 76 had vomiting (44.2%; 95% confidence interval [CI] 36.9%-51.7%), and in 285 with TBI CT, 123 had vomiting (43.2%; 95% CI 37.5%-49.0%). With isolated vomiting, only 1 (0.3%; 95% CI 0.0%-0.9%) had ciTBI and 2 (0.6%; 95% CI 0.0%-1.4%) had TBI-CT. Predictors of increased risk of ciTBI with vomiting by using multivariate regression were as follows: signs of skull fracture (odds ratio [OR] 80.1; 95% CI 43.4-148.0), altered mental status (OR 2.4; 95% CI 1.0-5.5), headache (OR 2.3; 95% CI 1.3-4.1), and acting abnormally (OR 1.86; 95% CI 1.0-3.4). Additional features predicting TBI-CT were as follows: skull fracture (OR 112.96; 95% CI 66.76-191.14), nonaccidental injury concern (OR 6.75; 95% CI 1.54-29.69), headache (OR 2.55; 95% CI 1.52-4.27), and acting abnormally (OR 1.83; 95% CI 1.10 3.06). CONCLUSIONS: TBI-CT and ciTBI are uncommon in children presenting with head injury with isolated vomiting, and a management strategy of observation without immediate computed tomography appears appropriate.

PMID- 29599115 TI - The UPRmt Protects Caenorhabditis elegans from Mitochondrial Dysfunction by Upregulating Specific Enzymes of the Mevalonate Pathway. AB - The mevalonate pathway is the primary target of the cholesterol-lowering drugs statins, some of the most widely prescribed medicines of all time. The pathway's enzymes not only catalyze the synthesis of cholesterol but also of diverse metabolites such as mitochondrial electron carriers and isoprenyls. Recently, it has been shown that one type of mitochondrial stress response, the UPRmt, can protect yeast, Caenorhabditis elegans, and cultured human cells from the deleterious effects of mevalonate pathway inhibition by statins. The mechanistic basis for this protection, however, remains unknown. Using C. elegans, we found that the UPRmt does not directly affect the levels of the statin target HMG-CoA reductase, the rate-controlling enzyme of the mevalonate pathway in mammals. Instead, in C. elegans the UPRmt upregulates the first dedicated enzyme of the pathway, HMG-CoA synthase (HMGS-1). A targeted RNA interference (RNAi) screen identified two UPRmt transcription factors, ATFS-1 and DVE-1, as regulators of HMGS-1 A comprehensive analysis of the pathway's enzymes found that, in addition to HMGS-1, the UPRmt upregulates enzymes involved with the biosynthesis of electron carriers and geranylgeranylation intermediates. Geranylgeranylation, in turn, is requisite for the full execution of the UPRmt 3response. Thus, the UPRmt acts in at least three coordinated, compensatory arms to upregulate specific branches of the mevalonate pathway, thereby alleviating mitochondrial stress. We propose that statin-mediated inhibition of the mevalonate pathway blocks this compensatory system of the UPRmt and consequentially impedes mitochondrial homeostasis. This effect is likely one of the principal bases for the adverse side effects of statins. PMID- 29599118 TI - Risk assessment in pulmonary arterial hypertension.

AB - OBJECTIVE: To estimate the incidence proportion (IP) and incidence rate (IR) of ACL injury in football players. DESIGN: Systematic review with meta-analysis. DATA SOURCES: PubMed, CINAHL and SPORTDiscus electronic databases were searched from inception to 20 January 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDY: Studies that reported the total number of participants/population by sex, total number of ACL injuries by sex and total person-time by sex were included. RESULTS: Twenty-eight studies were included. The IP and IR of ACL injury in female football players were 2.0% (95% CI 1.2% to 3.1%) and 2.0/10 000 athlete exposures (AEs) (95% CI 1.6 to 2.6; I2=91%) over a period of one season to 4 years. The IP and IR of ACL injury in male players were 3.5% (95% CI 0.7% to 8.2%) and 0.9/10 000 AEs (95% CI 0.7 to 1.1; I2=94%). Studies that evaluated matched cohorts of female and male players showed no difference in IP (relative risk=1.2; 95% CI 0.9 to 1.6; P=0.47) over a period of one season to 4 years. Women were at greater risk than men (incidence rate ratio (IRR)=2.2; 95% CI 1.6 to 3.1; I2=83%; P<0.001). When accounting for participation level, the difference in IR between women and men was greatest for intermediate players (IRR=2.9; 95% CI 2.4 to 3.6) compared with amateur (IRR=2.6; 95% CI 1.4 to 4.8) and elite (IRR=2.0; 95% CI 1.1 to 3.4) players. SUMMARY/CONCLUSION: Overall, more men sustained ACL injury in football. There was no difference in the relative risk of ACL injury between female and male football players in a window that spanned one season to 4 years. The IR of ACL injury among women was 2.2 times higher than the IR of ACL injury among men. The reported sex disparity in ACL injury was independent of participation level. PMID- 29599122 TI - Intersectin goes nuclear: secret life of an endocytic protein. AB - Intersectin 1-short (ITSN1-s) is a 1220 amino acid ubiquitously expressed scaffold protein presenting a multidomain structure that allows to spatiotemporally regulate the functional interaction of a plethora of proteins. Besides its well-established role in endocytosis, ITSN1-s is involved in the regulation of cell signaling and is implicated in tumorigenesis processes, although the signaling pathways involved are still poorly understood. Here, we identify ITSN1-s as a nucleocytoplasmic trafficking protein. We show that, by binding to importin (IMP)alpha, a small fraction of ITSN1-s localizes in the cell nucleus at the steady state, where it preferentially associates with the nuclear envelope and interacts with lamin A/C. However, upon pharmacological ablation of chromosome region maintenance 1 (CRM-1)-dependent nuclear export pathway, the protein accumulates into the nucleus, thus revealing its moonlighting nature. Analysis of deletion mutants revealed that the coiled coil (CC) and Src homology (SH3) regions play the major role in its nucleocytoplasmic shuttling. While no evidence of nuclear localization signal (NLS) was detected in the CC region, a functional bipartite NLS was identified within the SH3D region of ITSN1-s (RKKNPGGWWEGELQARGKKRQIGW-1127), capable of conferring energy-dependent nuclear accumulation to reporter proteins and whose mutational ablation affects nuclear import of the whole SH3 region. Thus, ITSN1-s is an endocytic protein, which shuttles between the nucleus and the cytoplasm in a CRM-1- and IMPalpha-dependent fashion. PMID- 29599123 TI - Tumor suppressor functions of DAXX through histone H3.3/H3K9me3 pathway in pancreatic NETs. AB - Pancreatic neuroendocrine tumors (PanNETs) have considerable malignant potential. Frequent somatic mutations and loss of DAXX protein expression have been found in PanNETs. DAXX is known as a transcriptional repressor; however, molecular functions underlying DAXX loss remain unclear in PanNETs. We evaluated DAXX expression by immunohistochemistry in 44 PanNETs. DAXX-knockdown (KD) and knockout (KO) PanNET cells were analyzed for in vitro and vivo The target genes were screened by microarray and chromatin immunoprecipitation (ChIP) assays for DAXX, histone H3.3 and H3K9me3 complex. In clinicopathological features, low DAXX expression was significantly correlated with nonfunctional tumors, higher Ki-67 index and WHO grade. Microarray and ChIP assays of DAXX-KD/KO identified 12 genes as the direct targets of DAXX transcriptional repressor. Among them, expression of five genes including STC2 was suppressed by DAXX/H3.3/H3K9me3 pathway. DAXX KD/KO cells enhanced sphere forming activity, but its effect was suppressed by knockdown of STC2 In xenograft models, tumorigenicity and tumor vessel density were significantly increased in DAXX-KO cells with high expression of STC2. Clinically, higher recurrence rate was recognized in PanNETs with low expression of DAXX and high expression of STC2 than others (P = 0.018). Our data suggest that DAXX plays as a tumor suppressor and DAXX/H3.3 complex suppresses target genes by promoting H3K9me3 in PanNETs. Combination of DAXX loss and its target gene STC2 overexpression might be effective biomarkers and therapeutic candidates. PMID- 29599124 TI - Single drug biomarker prediction for ER- breast cancer outcome from chemotherapy. AB - ER-negative breast cancer includes most aggressive subtypes of breast cancer such as triple negative (TN) breast cancer. Excluded from hormonal and targeted therapies effectively used for other subtypes of breast cancer, standard chemotherapy is one of the primary treatment options for these patients. However, as ER- patients have shown highly heterogeneous responses to different chemotherapies, it has been difficult to select most beneficial chemotherapy treatments for them. In this study, we have simultaneously developed single drug biomarker models for four standard chemotherapy agents: paclitaxel (T), 5 fluorouracil (F), doxorubicin (A) and cyclophosphamide (C) to predict responses and survival of ER- breast cancer patients treated with combination chemotherapies. We then flexibly combined these individual drug biomarkers for predicting patient outcomes of two independent cohorts of ER- breast cancer patients who were treated with different drug combinations of neoadjuvant chemotherapy. These individual and combined drug biomarker models significantly predicted chemotherapy response for 197 ER- patients in the Hatzis cohort (AUC = 0.637, P = 0.002) and 69 ER- patients in the Hess cohort (AUC = 0.635, P = 0.056). The prediction was also significant for the TN subgroup of both cohorts (AUC = 0.60, 0.72, P = 0.043, 0.009). In survival analysis, our predicted responder patients showed significantly improved survival with a >17 months longer median PFS than the predicted non-responder patients for both ER- and TN subgroups (log-rank test P-value = 0.018 and 0.044). This flexible prediction capability based on single drug biomarkers may allow us to even select new drug combinations most beneficial to individual patients with ER- breast cancer.

The engrafted beta-like cells expressed beta cell transcription factors and markers associated with functional maturity. Engrafted human cells recruited mouse endothelial cells, suggesting functional integration. Human insulin was detected in the blood circulation of transplanted mice for months after transplantation and increased upon glucose stimulation. In addition to beta-like cells, human cells expressing markers for other endocrine pancreas cell types, acinar cells, and pancreatic ductal cells were identified in the pancreata of transplanted mice, indicating that this approach allows studying other human pancreatic cell types in the mouse pancreas. Our results demonstrate that orthotopic transplantation of human SC beta cells into neonatal mice is an experimental platform that allows the generation of mice with human pancreatic beta-like cells in the endogenous niche.

AB - CaThi is a thionin-like peptide isolated from fruits of Capsicum annuum, which has strong antimicrobial activity against bacteria, yeasts and filamentous fungi, and induced reactive oxygen species (ROS) in fungi. ROS are molecules that appear in the early stages of programmed cell death or apoptosis in fungi. Due to this fact, in this work we analyzed some events that may be related to process of apoptosis on yeast induced by CaThi. To investigate this possibility, we evaluated phosphatidylserine (PS) externalization, presence of active caspases and the ability of CaThi to bind to DNA in Candida tropicalis cells. Additionally, we investigated mitochondrial membrane potential, cell surface pH, and extracellular H+ fluxes in C. tropicalis cells after treatment with CaThi. Our results showed that CaThi induced PS externalization in the outer leaflet of the cell membrane, activation of caspases, and it had the ability for DNA binding and to dissipate mitochondrial membrane potential. In addition, the cell surface pH increased significantly when the C. tropicalis cells were exposed to CaThi which corroborates with ~96% inhibition on extracellular H+ efflux. Taking together, these data suggest that this peptide is capable of promoting an imbalance in pH homeostasis during yeast cell death playing a modulatory role in the H+ transport systems. In conclusion, our results strongly indicated that CaThi triggers apoptosis in C. tropicalis cells, involving a pH signaling mechanism.

AB - Interferon regulatory factors (IRFs) are a group of closely related proteins collectively referred to as the IRF family. Members of this family were originally recognized for their roles in inflammatory responses; however, recent research has suggested that they are also involved in tumor biology. This review focusses on current knowledge of the roles of IRF-1 and IRF-2 in human cancer, with particular attention paid to the impact of IRF-1 inactivation. The different mechanisms underlying IRF-1 inactivation and their implications for human cancers and the potential importance of IRF-1 in immunotherapy are also summarized.

AB - : Backgroud: Obstructive jaundice increases intestinal permeability, but the pathological mechanisms remain obscure, which results in debates about the necessity of performing preoperative biliary drainage in patients with obstructive jaundice. Mucin-2 (MUC2) and goblet cells regulated by bile acids play an important role in maintaining the function of intestinal mucosal barrier. The present study was to investigate the role of goblet cells and MUC2 in obstructive jaundice and evaluate the effect of biliary drainage on intestinal permeability. STUDY DESIGN: We enrolled patients with malignant biliary obstruction and controls. We also did animal studies with four groups of rats: sham operation, obstructive jaundice, internal biliary drainage, and external biliary drainage. Histopathological analysis, biochemical measurement, and electron microscopy examination were done on pertinent samples. RESULTS: Compared with the control group, the small intestinal mucosa was significantly damaged; goblet cells and MUC2 were significantly decreased and serum endotoxin level was significantly increased in patients and rats with obstructive jaundice. Biliary drainage, especially internal biliary drainage, significantly increased goblet cells and MUC2 and attenuated the damage of small intestinal mucosa. CONCLUSIONS: In obstructive jaundice condition, goblet cells and MUC2 were reduced which were involved in the damage of intestinal mucosa barrier; biliary drainage increased goblet cells and MUC2, repaired mucosa layer and restored the intestinal mucosa barrier function.

PMID- 29599129 TI - 5-aminoisoquinoline improves renal function and fibrosis during recovery phase of cisplatin-induced acute kidney injury in rats. AB - The aim of the present study is to analyze the effects of 5-aminoisoquinoline (5 AIQ), a poly(ADP-ribose) polymerase-1 (PARP1) inhibitor, over renal dysfunction and fibrosis during recovery phase of cisplatin (CisPt)-induced acute kidney injury (AKI) in rats. Male Wistar rats were distributed in three groups (n=8 each group): control, CisPt, and CisPt + 5-AIQ. Control and CisPt groups received a subcutaneous injection of either saline or 7 mg/kg CisPt, respectively. CisPt + 5 AIQ group received two intraperitoneal injections of 10 mg/kg 5-AIQ 2 h before and 24 h after CisPt treatment. Thirteen days after the treatment, rats were housed in metabolic cages and 24-h urine collection was made. At day 14, CisPt treated rats showed increased diuresis, N-acetyl-beta-d-glucosaminidase (NAG) excretion, glucosuria and sodium fractional excretion (NaFE), and decreased creatinine clearance (CrCl). 5-AIQ significantly increased CrCl and decreased NAG excretion, glucosuria, and NaFE. In plasma, CisPt increased sodium, urea, and creatinine concentrations, while 5-AIQ treatment decreased these variables to the levels of control group. 5-AIQ completely prevented the body weight loss evoked by CisPt treatment. CisPt also induced an increased renal expression of PAR polymer, alpha-smooth muscle actin (alpha-SMA), transforming growth factor-beta1 (TGF-beta1), and collagen-IV. These variables were decreased in CisPt + 5-AIQ group. Tubular lesions and renal fibrosis were also decreased by 5-AIQ treatment. We conclude that inhibition of PARP1 with 5-AIQ can attenuate long-term nephrotoxic effects associated with the CisPt treatment, preventing renal dysfunction and body weight decrease and ameliorating tubular lesions and collagen deposition. PMID- 29599132 TI - CaMKII (Ca2+/Calmodulin-Dependent Kinase II) in Mitochondria of Smooth Muscle Cells Controls Mitochondrial Mobility, Migration, and Neointima Formation. AB - OBJECTIVE: The main objective of this study is to define the mechanisms by which mitochondria control vascular smooth muscle cell (VSMC) migration and impact neointimal hyperplasia. APPROACH AND RESULTS: The multifunctional CaMKII (Ca2+/calmodulin-dependent kinase II) in the mitochondrial matrix of VSMC drove a feed-forward circuit with the mitochondrial Ca2+ uniporter (MCU) to promote matrix Ca2+ influx. MCU was necessary for the activation of mitochondrial CaMKII (mtCaMKII), whereas mtCaMKII phosphorylated MCU at the regulatory site S92 that promotes Ca2+ entry. mtCaMKII was necessary and sufficient for platelet-derived growth factor-induced mitochondrial Ca2+ uptake. This effect was dependent on MCU. mtCaMKII and MCU inhibition abrogated VSMC migration and mitochondrial translocation to the leading edge. Overexpression of wild-type MCU, but not MCU S92A, mutant in MCU-/- VSMC rescued migration and mitochondrial mobility. Inhibition of microtubule, but not of actin assembly, blocked mitochondrial mobility. The outer mitochondrial membrane GTPase Miro-1 promotes mitochondrial mobility via microtubule transport but arrests it in subcellular domains of high Ca2+ concentrations. In Miro-1-/- VSMC, mitochondrial mobility and VSMC migration were abolished, and overexpression of mtCaMKII or a CaMKII inhibitory peptide in mitochondria (mtCaMKIIN) had no effect. Consistently, inhibition of mtCaMKII increased and prolonged cytosolic Ca2+ transients. mtCaMKII inhibition diminished phosphorylation of focal adhesion kinase and myosin light chain, leading to reduced focal adhesion turnover and cytoskeletal remodeling. In a transgenic model of selective mitochondrial CaMKII inhibition in VSMC, neointimal hyperplasia was significantly reduced after vascular injury. CONCLUSIONS: These findings identify mitochondrial CaMKII as a key regulator of mitochondrial Ca2+ uptake via MCU, thereby controlling mitochondrial translocation and VSMC migration after vascular injury. PMID- 29599133 TI - LAL (Lysosomal Acid Lipase) Promotes Reverse Cholesterol Transport In Vitro and In Vivo. AB - OBJECTIVE: To explore the role of LAL (lysosomal acid lipase) in macrophage cholesterol efflux and whole-body reverse cholesterol transport. APPROACH AND RESULTS: Immortalized peritoneal macrophages from lal-/- mice showed reduced expression of ABCA1 (ATP-binding cassette transporter A1) and ABCG1 (ATP-binding cassette transporter G1), reduced production of the regulatory oxysterol 27 hydroxycholesterol, and impaired suppression of cholesterol synthesis on exposure to acetylated low-density lipoprotein when compared with lal+/+ macrophages. LAL deficient mice also showed reduced hepatic ABCG5 (ATP-binding cassette transporter G5) and ABCG8 (ATP-binding cassette transporter G8) expression compared with lal+/+ mice. LAL-deficient macrophages loaded with [3H]-cholesteryl oleate-labeled acetylated low-density lipoprotein showed impaired efflux of released [3H]-cholesterol to apoA-I (apolipoprotein A-I), with normalization of [3H]-cholesteryl ester levels and partial correction of ABCA1 expression and cholesterol efflux to apoA-I when treated with exogenous rhLAL (recombinant human LAL protein). LAL-deficient mice injected intraperitoneally with lal-/- macrophages cholesterol loaded and labeled in the same way exhibited only 1.55+/ 0.35% total injected [3H]-cholesterol counts appearing in the feces for 48 h (n=30), compared with 5.38+/-0.92% in lal+/+ mice injected with labeled lal+/+ macrophages (n=27), P<0.001. To mimic the therapeutic condition of delivery of supplemental LAL in vivo, injection of labeled lal-/- macrophages into lal+/+ mice resulted in a significant increase in reverse cholesterol transport (2.60+/ 0.46% of 3H-cholesterol counts in feces at 48 hours [n=19]; P<0.001 when compared with injection into lal-/- mice). CONCLUSIONS: These results indicate a critical role for LAL in promoting both macrophage and whole-body reverse cholesterol transport and the ability of supplemental LAL to be taken up and correct reverse cholesterol transport in vivo. PMID- 29599134 TI - Extracellular and Intracellular Cyclophilin A, Native and Post-Translationally Modified, Show Diverse and Specific Pathological Roles in Diseases. AB - CypA (cyclophilin A) is a ubiquitous and highly conserved protein with peptidyl prolyl isomerase activity. Because of its highly abundant level in the cytoplasm, most studies have focused on the roles of CypA as an intracellular protein. However, emerging evidence suggests an important role for extracellular CypA in the pathogenesis of several diseases through receptor (CD147 or other)-mediated autocrine and paracrine signaling pathways. In this review, we will discuss the shared and unique pathological roles of extracellular and intracellular CypA in human cardiovascular diseases. In addition, the evolving role of post translational modifications of CypA in the pathogenesis of disease is discussed. Finally, recent studies with drugs specific for extracellular CypA show its importance in disease pathogenesis in several animal models and make extracellular CypA a new therapeutic target. PMID- 29599135 TI - PAR2 (Protease-Activated Receptor 2) Deficiency Attenuates Atherosclerosis in Mice. AB - OBJECTIVE: PAR2 (protease-activated receptor 2)-dependent signaling results in augmented inflammation and has been implicated in the pathogenesis of several autoimmune conditions. The objective of this study was to determine the effect of PAR2 deficiency on the development of atherosclerosis. APPROACH AND RESULTS: PAR2 mRNA and protein expression is increased in human carotid artery and mouse aortic arch atheroma versus control carotid and aortic arch arteries, respectively. To determine the effect of PAR2 deficiency on atherosclerosis, male and female low density lipoprotein receptor-deficient (Ldlr-/-) mice (8-12 weeks old) that were Par2+/+ or Par2-/- were fed a fat- and cholesterol-enriched diet for 12 or 24 weeks. PAR2 deficiency attenuated atherosclerosis in the aortic sinus and aortic root after 12 and 24 weeks. PAR2 deficiency did not alter total plasma cholesterol concentrations or lipoprotein distributions. Bone marrow transplantation showed that PAR2 on nonhematopoietic cells contributed to atherosclerosis. PAR2 deficiency significantly attenuated levels of the chemokines Ccl2 and Cxcl1 in the circulation and macrophage content in atherosclerotic lesions. Mechanistic studies using isolated primary vascular smooth muscle cells showed that PAR2 deficiency is associated with reduced Ccl2 and Cxcl1 mRNA expression and protein release into the supernatant resulting in less monocyte migration. CONCLUSIONS: Our results indicate that PAR2 deficiency is associated with attenuation of atherosclerosis and may reduce lesion progression by blunting Ccl2- and Cxcl1-induced monocyte infiltration. PMID- 29599136 TI - Deficiency of Dab2 (Disabled Homolog 2) in Myeloid Cells Exacerbates Inflammation in Liver and Atherosclerotic Plaques in LDLR (Low-Density Lipoprotein Receptor) Null Mice-Brief Report. AB - OBJECTIVE: Inflammatory macrophages promote the development of atherosclerosis. We have identified the adaptor protein Dab2 (disabled homolog 2) as a regulator of phenotypic polarization in macrophages. The absence of Dab2 in myeloid cells promotes an inflammatory phenotype, but the impact of myeloid Dab2 deficiency on atherosclerosis has not been shown. APPROACH AND RESULTS: To determine the role of myeloid Dab2 in atherosclerosis, Ldlr-/- mice were reconstituted with either Dab2-positive or Dab2-deficient bone marrow and fed a western diet. Consistent with our previous finding that Dab2 inhibits NFkappaB (nuclear factor kappa-light chain-enhancer of activated B cells) signaling in macrophages, Ldlr-/- mice reconstituted with Dab2-deficient bone marrow had increased systemic inflammation as evidenced by increased serum IL-6 (interleukin-6) levels and increased inflammatory cytokine expression levels in liver. Serum lipid levels were significantly lower in Ldlr-/- mice reconstituted with Dab2-deficient bone marrow, and further examination of livers from these mice revealed drastically increased inflammatory tissue damage and massive infiltration of immune cells. Surprisingly, the atherosclerotic lesion burden in Ldlr-/- mice reconstituted with Dab2-deficient bone marrow was decreased compared with Ldlr-/- mice reconstituted with wild-type bone marrow. Further analysis of aortic root sections revealed increased macrophage content and evidence of increased apoptosis in lesions from Ldlr-/- mice reconstituted with Dab2-deficient bone marrow but no difference in collagen or alpha-smooth muscle actin content. CONCLUSIONS: Dab2 deficiency in myeloid cells promotes inflammation in livers and atherosclerotic plaques in a mouse model of atherosclerosis. Nevertheless, decreased serum lipids as a result of massive inflammatory liver damage may preclude an appreciable increase in atherosclerotic lesion burden in mice reconstituted with Dab2-deficient bone marrow. PMID- 29599137 TI - Afadin Facilitates Vascular Endothelial Growth Factor-Induced Network Formation and Migration of Vascular Endothelial Cells by Inactivating Rho-Associated Kinase Through ArhGAP29. AB - OBJECTIVE: We previously reported that afadin, an actin filament-binding protein, regulated vascular endothelial growth factor-induced angiogenesis. However, the underlying molecular mechanisms are poorly understood. Here, we investigated the mechanisms of how Rho-associated kinase is activated in afadin-knockdown human umbilical vein endothelial cells (HUVECs) and how its activation is involved in defects of vascular endothelial growth factor-induced network formation and migration of the cells. APPROACH AND RESULTS: Knockdown of afadin or ArhGAP29, a GTPase-activating protein for RhoA, increased Rho-associated kinase activity and reduced the vascular endothelial growth factor-induced network formation and migration of cultured HUVECs, accompanied by the defective formation of membrane protrusions, such as lamellipodia and peripheral ruffles. Treatment of the afadin or ArhGAP29-knockdown HUVECs with Rho-associated kinase inhibitors, Y-27632 or fasudil, partially restored the reduced network formation and migration as well as the defective formation of membrane protrusions. ArhGAP29 bound to afadin and was colocalized with afadin at the leading edge of migrating HUVECs. The defective formation of membrane protrusions in ArhGAP29-knockdown HUVECs was restored by expression of mutant ArhGAP29 that bound to afadin and contained a RhoGAP domain but not mutant ArhGAP29 that could bind to afadin and lacked the RhoGAP domain or mutant ArhGAP29 that could not bind to afadin and contained the RhoGAP domain. This suggested the requirement of both the interaction of afadin with ArhGAP29 and RhoGAP activity of ArhGAP29 for migration of HUVECs. CONCLUSIONS: Our results highlight a critical role of the afadin-ArhGAP29 axis for the regulation of Rho-associated kinase activity during vascular endothelial growth factor-induced network formation and migration of HUVECs. PMID- 29599138 TI - Telomerase Mediates Lymphocyte Proliferation but Not the Atherosclerosis Suppressive Potential of Regulatory T-Cells. AB - OBJECTIVE: Atherosclerosis is an age-related disease characterized by systemic oxidative stress and low-grade inflammation. The role of telomerase and telomere length in atherogenesis remains contentious. Short telomeres of peripheral leukocytes are predictive for coronary artery disease. Conversely, attenuated telomerase has been demonstrated to be protective for atherosclerosis. Hence, a potential causative role of telomerase in atherogenesis is critically debated. APPROACH AND RESULTS: In this study, we used multiple mouse models to investigate the regulation of telomerase under oxidative stress as well as its impact on atherogenesis in vitro and in vivo. Using primary lymphocytes and myeloid cell cultures, we demonstrate that cultivation under hyperoxic conditions induced oxidative stress resulting in chronic activation of CD4+ cells and significantly reduced CD4+ T-cell proliferation. The latter was telomerase dependent because oxidative stress had no effect on the proliferation of primary lymphocytes isolated from telomerase knockout mice. In contrast, myeloid cell proliferation was unaffected by oxidative stress nor reliant on telomerase. Telomerase reverse transcriptase deficiency had no effect on regulatory T-cell (Treg) numbers in vivo or suppressive function ex vivo. Adoptive transfer of telomerase reverse transcriptase-/- Tregs into Rag2-/- ApoE-/- (recombination activating gene 2/apolipoprotein E) double knockout mice demonstrated that telomerase function was not required for the ability of Tregs to protect against atherosclerosis. However, telomere length was critical for Treg function. CONCLUSIONS: Telomerase contributes to lymphocyte proliferation but plays no major role in Treg function, provided that telomere length is not critically short. We suggest that oxidative stress may contribute to atherosclerosis via suppression of telomerase and acceleration of telomere attrition in Tregs. PMID- 29599139 TI - Protective Role of mPGES-1 (Microsomal Prostaglandin E Synthase-1)-Derived PGE2 (Prostaglandin E2) and the Endothelial EP4 (Prostaglandin E Receptor) in Vascular Responses to Injury. AB - OBJECTIVE: Deletion of mPGES-1 (microsomal prostaglandin E synthase-1)-an anti inflammatory target alternative to COX (cyclooxygenase)-2-attenuates injury induced neointima formation in mice. This is attributable to the augmented levels of PGI2 (prostacyclin)-a known restraint of the vascular response to injury, acting via IP (I prostanoid receptor). To examine the role of mPGES-1-derived PGE2 (prostaglandin E2) in vascular remodeling without the IP. APPROACH AND RESULTS: Mice deficient in both IP and mPGES-1 (DKO [double knockout] and littermate controls [IP KO (knockout)]) were subjected to angioplasty wire injury. Compared with the deletion of IP alone, coincident deletion of IP and mPGES-1 increased neointima formation, without affecting media area. Early pathological changes include impaired reendothelialization and increased leukocyte invasion in neointima. Endothelial cells (ECs), but not vascular smooth muscle cells, isolated from DKOs exhibited impaired cell proliferation. Activation of EP (E prostanoid receptor) 4 (and EP2, to a lesser extent), but not of EP1 or EP3, promoted EC proliferation. EP4 antagonism inhibited proliferation of mPGES-1-competent ECs, but not of mPGES-1-deficient ECs, which showed suppressed PGE2 production. EP4 activation inhibited leukocyte adhesion to ECs in vitro, promoted reendothelialization, and limited neointima formation post-injury in the mouse. Endothelium-restricted deletion of EP4 in mice suppressed reendothelialization, increased neointimal leukocytes, and exacerbated neointimal formation. CONCLUSIONS: Removal of the IP receptors unmasks a protective role of mPGES-1-derived PGE2 in limiting injury-induced vascular hyperplasia. EP4, in the endothelial compartment, is essential to promote reendothelialization and restrain neointimal formation after injury. Activating EP4 bears therapeutic potential to prevent restenosis after percutaneous coronary intervention. PMID- 29599140 TI - Follicular B Cells Promote Atherosclerosis via T Cell-Mediated Differentiation Into Plasma Cells and Secreting Pathogenic Immunoglobulin G. AB - OBJECTIVE: B cells promote or protect development of atherosclerosis. In this study, we examined the role of MHCII (major histocompatibility II), CD40 (cluster of differentiation 40), and Blimp-1 (B-lymphocyte-induced maturation protein) expression by follicular B (FO B) cells in development of atherosclerosis together with the effects of IgG purified from atherosclerotic mice. APPROACH AND RESULTS: Using mixed chimeric Ldlr-/- mice whose B cells are deficient in MHCII or CD40, we demonstrate that these molecules are critical for the proatherogenic actions of FO B cells. During development of atherosclerosis, these deficiencies affected T-B cell interactions, germinal center B cells, plasma cells, and IgG. As FO B cells differentiating into plasma cells require Blimp-1, we also assessed its role in the development of atherosclerosis. Blimp-1-deficient B cells greatly attenuated atherosclerosis and immunoglobulin-including IgG production, preventing IgG accumulation in atherosclerotic lesions; Blimp-1 deletion also attenuated lesion proinflammatory cytokines, apoptotic cell numbers, and necrotic core. To determine the importance of IgG for atherosclerosis, we purified IgG from atherosclerotic mice. Their transfer but not IgG from nonatherosclerotic mice into Ldlr-/- mice whose B cells are Blimp-1-deficient increased atherosclerosis; transfer was associated with IgG accumulating in atherosclerotic lesions, increased lesion inflammatory cytokines, apoptotic cell numbers, and necrotic core size. CONCLUSIONS: The mechanism by which FO B cells promote atherosclerosis is highly dependent on their expression of MHCII, CD40, and Blimp 1. FO B cell differentiation into IgG-producing plasma cells also is critical for their proatherogenic actions. Targeting B-T cell interactions and pathogenic IgG may provide novel therapeutic strategies to prevent atherosclerosis and its adverse cardiovascular complications. PMID- 29599141 TI - Switch in Laminin beta2 to Laminin beta1 Isoforms During Aging Controls Endothelial Cell Functions-Brief Report. AB - OBJECTIVE: Endothelial cells play important roles in tissue homeostasis and vascularization, a function that is impaired by aging. Here, we aim to decipher the role of the microenvironment underlying the impairment of endothelial cell functions by aging. APPROACH AND RESULTS: RNA sequencing of isolated cardiac endothelial cells derived from young and 18-month-old mouse hearts revealed that aging affects the endothelial expression of genes encoding extracellular matrix proteins, specifically the laminin beta1 (Lamb1) and laminin beta2 (Lamb2) chains. Whereas Lamb1 was upregulated, Lamb2 was decreased in endothelial cells in old mice compared with young controls. A similar change in expression patterns was observed after induction of acute myocardial infarction. Mimicking aging and injury conditions by plating endothelial cells on laminin beta1-containing laminin 411 matrix impaired endothelial cell adhesion, migration, and tube formation and augmented endothelial-to-mesenchymal transition and endothelial detachment compared with laminin 421, which contains the laminin beta2 chain. Because laminins can signal via integrin receptors, we determined the activation of ITGB1 (integrin beta1). Laminin 421 coating induced a higher activation of ITGB1 compared with laminin 411. siRNA-mediated silencing of ITGB1 reduced laminin beta2-dependent adhesion, suggesting that laminin beta2 more efficiently activates ITGB1. CONCLUSIONS: Mimicking age-related modulation of laminin beta1 versus beta2 chain expression changes the functional properties and phenotype of endothelial cells. The dysregulation of the extracellular matrix during vascular aging may contribute to age-associated impairment of organ function and fibrosis.

AB - Aggregation of alpha-synuclein is a hallmark of Parkinson's disease and dementia with Lewy bodies. We here investigate the relationship between cytosolic Ca2+ and alpha-synuclein aggregation. Analyses of cell lines and primary culture models of alpha-synuclein cytopathology reveal an early phase with reduced cytosolic Ca2+ levels followed by a later Ca2+ increase. Aggregated but not monomeric alpha synuclein binds to and activates SERCA in vitro, and proximity ligation assays confirm this interaction in cells. The SERCA inhibitor cyclopiazonic acid (CPA) normalises both the initial reduction and the later increase in cytosolic Ca2+ CPA protects the cells against alpha-synuclein-aggregate stress and improves viability in cell models and in Caenorhabditis elegans in vivo Proximity ligation assays also reveal an increased interaction between alpha-synuclein aggregates and SERCA in human brains affected by dementia with Lewy bodies. We conclude that alpha-synuclein aggregates bind SERCA and stimulate its activity. Reducing SERCA activity is neuroprotective, indicating that SERCA and down-stream processes may be therapeutic targets for treating alpha-synucleinopathies.

PMID- 29599164 TI - Incident CTS in a large pooled cohort study: associations obtained by a Job Exposure Matrix versus associations obtained from observed exposures. AB - BACKGROUND: There is growing use of a job exposure matrix (JEM) to provide exposure estimates in studies of work-related musculoskeletal disorders; few studies have examined the validity of such estimates, nor did compare associations obtained with a JEM with those obtained using other exposures. OBJECTIVE: This study estimated upper extremity exposures using a JEM derived from a publicly available data set (Occupational Network, O*NET), and compared exposure-disease associations for incident carpal tunnel syndrome (CTS) with those obtained using observed physical exposure measures in a large prospective study. METHODS: 2393 workers from several industries were followed for up to 2.8 years (5.5 person-years). Standard Occupational Classification (SOC) codes were assigned to the job at enrolment. SOC codes linked to physical exposures for forceful hand exertion and repetitive activities were extracted from O*NET. We used multivariable Cox proportional hazards regression models to describe exposure-disease associations for incident CTS for individually observed physical exposures and JEM exposures from O*NET. RESULTS: Both exposure methods found associations between incident CTS and exposures of force and repetition, with evidence of dose-response. Observed associations were similar across the two methods, with somewhat wider CIs for HRs calculated using the JEM method. CONCLUSION: Exposures estimated using a JEM provided similar exposure-disease associations for CTS when compared with associations obtained using the 'gold standard' method of individual observation. While JEMs have a number of limitations, in some studies they can provide useful exposure estimates in the absence of individual-level observed exposures.

PMID- 29599167 TI - Quality of life in young people with congenital heart disease is better than expected. AB - OBJECTIVES: Improved treatments for patients with congenital heart disease (CHD) have led to a growing interest in long-term functional outcomes such as health related quality of life (HRQoL). Studies on HRQoL in children with CHD have contradicting results. Therefore, we compared HRQoL of children with CHD with that of current healthy peers and stratify CHD cases by severity and diagnostic subgroups. METHODS: We included 514 patients (191 girls) aged 7-17 (12.9+/-3.1) years who were recruited at our institution between July 2014 and May 2017. The self-reported and age-adapted KINDL questionnaire was used to assess HRQoL. Patient data were compared with that of a recent control group of 734 healthy children (346 girls, 13.4+/-2.1 years). RESULTS: Patients with CHD scored at least as high as healthy peers in HRQoL (CHD: 78.6+/-9.8; healthy: 75.6+/-10.1; P<0.001). After correction for sex and age, patients with CHD presented a 2.3 point higher HRQoL (P<0.001). The sex-specific and age-specific analyses showed that there were no differences between boys with and without CHD in childhood (P=0.255), but in adolescence, boys with CHD had on average 3.9-point higher scores (P=0.001), whereas girls with CHD had statistically higher HRQoL perception than healthy girls in childhood (4.2 points; P=0.003) and adolescence (4.2 points; P=0.005). There were no differences between the severity classes or diagnostic subgroups in the total HRQoL score or in the six subdomains. CONCLUSION: The high HRQoL in young patients with CHD suggests that they can cope well with their disease burden. This holds true for all severity classes and diagnostic subgroups. PMID- 29599169 TI - Aneurysmal Parent Artery-Specific Inflow Conditions for Complete and Incomplete Circle of Willis Configurations. AB - BACKGROUND AND PURPOSE: Hemodynamics are thought to play a role in intracranial aneurysm growth and rupture. Computational fluid dynamics is frequently performed to assess intra-aneurysmal hemodynamics, using generalized flow waveforms of healthy volunteers as inflow boundary conditions. The purpose of this study was to assess differences in inflow conditions for different aneurysmal parent artery locations and variations of circle of Willis configurations. MATERIALS AND METHODS: In a series of 96 patients with 103 aneurysms, velocity measurements were acquired using 2D phase-contrast MR imaging perpendicular to the aneurysmal parent arteries in the circle of Willis. Circle of Willis configurations were inspected for variations using multiple overlapping thin-slab-acquisition MRAs. Flow rates, velocity magnitudes, and pulsatility indices were calculated for each parent artery location in subgroups of complete and incomplete circle of Willis configurations. RESULTS: Flow rates, velocity magnitudes, and pulsatility indices were significantly different among aneurysmal parent arteries. Incomplete circle of Willis configurations were observed in 24% of the cases. Significantly lower basilar artery flow rates were observed in configurations with hypoplastic P1 segments. Significantly higher A1 flow rates were observed in configurations with a hypoplastic contralateral A1 segment. CONCLUSIONS: Inflow conditions vary substantially between aneurysmal parent arteries and circle of Willis configurations. We have created a collection of parent artery-specific inflow conditions tailored to the patient-specific circle of Willis configuration that can be used in future computational fluid dynamics studies analyzing intra aneurysmal hemodynamics. PMID- 29599170 TI - Blood Flow Mimicking Aneurysmal Wall Enhancement: A Diagnostic Pitfall of Vessel Wall MRI Using the Postcontrast 3D Turbo Spin-Echo MR Imaging Sequence. AB - Our aim was to compare the detectability of aneurysmal wall enhancement in unruptured intracranial aneurysms between conventional and motion-sensitized driven equilibrium-prepared postcontrast 3D T1-weighted TSE sequences (sampling perfection with applicationoptimized contrasts by using different flip angle evolution, SPACE). Twenty-two patients with 30 unruptured intracranial aneurysms were scanned at 3T. Aneurysmal wall enhancement was more significantly detected using conventional compared with motion-sensitized driven equilibrium-prepared SPACE sequences (10/30 versus 2/30, P < .0001). Contrast-to-noise ratio measurements did not differ between conventional and motion-sensitized driven equilibrium-prepared sequences (P = .51). Flowing blood can mimic aneurysmal wall enhancement using conventional SPACE sequences with potential implications for patient care. PMID- 29599171 TI - Signal Change of Acute Cortical and Juxtacortical Microinfarction on Follow-Up MRI. AB - BACKGROUND AND PURPOSE: Although the clinical importance of cortical microinfarcts has become well-recognized recently, the evolution of cortical microinfarcts on MR imaging is not fully understood. The aim of this study was to examine the temporal changes in acute cortical microinfarcts using susceptibility weighted imaging and conventional MR imaging. MATERIALS AND METHODS: Patients with acute infarcts located in the cortical and/or juxtacortical region measuring <=10 mm in axial diameter based on diffusion-weighted imaging who had a follow-up 3T MR imaging were retrospectively included in the study. All lesions did not show hypointensity on initial T2*WI. For cortical and/or juxtacortical microinfarcts detected on initial DWI, 2 neuroradiologists evaluated the follow up MR imaging (T2WI, FLAIR, T2*WI, and SWI) and assessed lesion signal intensities and locations (cortical microinfarcts or microinfarcts with juxtacortical white matter involvement). RESULTS: On initial DWI, 2 radiologists observed 180 cortical and/or juxtacortical microinfarcts in 35 MR imaging examinations in 25 patients; on follow-up, the neuroradiologists identified 29 cortical microinfarcts (16%) on T2WI, 9 (5%) on FLAIR, 4 (2%) on T2*, and 97 (54%) on SWI. All cortical microinfarcts detected with any follow-up MR imaging showed hyperintensity on T2WI/FLAIR and/or hypointensity on T2*WI and SWI. CONCLUSIONS: SWI revealed conversion (paramagnetic susceptibility changes) of acute cortical microinfarcts, suggesting that a substantial number of cortical microinfarcts may contain hemorrhagic components. PMID- 29599172 TI - Submandibular Gland Transfer: A Potential Imaging Pitfall. AB - BACKGROUND AND PURPOSE: The Seikaly and Jha submandibular gland transfer surgery is performed to facilitate gland shielding during radiation therapy for head and neck tumors to circumvent radiation-induced xerostomia. It results in an asymmetric postsurgical appearance of the submandibular and submental spaces. Our purpose was to characterize the morphologic and enhancement characteristics of the transferred submandibular gland and identify potential pitfalls in postoperative radiologic interpretation. MATERIALS AND METHODS: This retrospective study identified patients with head and neck cancer who had undergone the submandibular gland transfer procedure at our institution. Chart reviews were performed to identify relevant oncologic histories and therapies. CT and MR neck imaging was reviewed to characterize morphologic and enhancement characteristics of the pre- and postoperative submandibular glands, as well as interpretive accuracy. RESULTS: Eleven patients with oropharyngeal and nasopharyngeal squamous cell carcinomas who underwent submandibular gland transfer were identified. The transferred glands were significantly lengthened in the anteroposterior dimension compared with contralateral glands (P < .001) and displaced anteriorly and inferiorly within the submandibular and submental spaces. Enhancement patterns of the transferred submandibular glands varied, depending on the time of imaging relative to the operation and radiation therapy. Submandibular gland transfer was acknowledged in the postoperative report in 7/11 cases. Errors in interpretation were present in 2/11 reports. CONCLUSIONS: After the submandibular gland transfer procedure, the submandibular and submental spaces lose their symmetric appearances as the transferred submandibular glands become lengthened and located more anteriorly and inferiorly, with variable enhancement characteristics. Familiarity with the postsurgical appearance of the transferred submandibular glands is key to accurate imaging interpretation. PMID- 29599173 TI - Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter: A Multicenter, Randomized, Controlled Clinical Trial (PARAT). AB - BACKGROUND AND PURPOSE: Although flow diverters have been reported with favorable clinical and angiographic outcomes in various literatures, randomized trials determining their true effectiveness and safety are still in lack. The Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter (PARAT) trial was designed to evaluate the safety and efficacy of the Tubridge flow diverter in the treatment of large or giant aneurysms in comparison with Enterprise stent-assisted coiling. MATERIALS AND METHODS: This prospective, multicenter, randomized trial was conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel-related stroke, aneurysm bleeding, in stent stenosis, parent artery occlusion, and the frequency of all adverse events. RESULTS: Among 185 enrolled subjects, 41 withdrew before procedure initiation. Overall, 82 subjects underwent Tubridge implantation, and 62 subjects were primarily treated with stent-assisted coiling. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively, with a calculated common odds ratio of 9.4 (95% confidence interval, 4.14-21.38; P < .001). There was a higher, nonsignificant frequency of complications for Tubridge subjects. Multivariate analysis showed a decreased stroke rate at the primary investigational site, with a marginal P value (P = .051). CONCLUSIONS: This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs. PMID- 29599174 TI - An Update on the Adjunctive Neurovascular Support of Wide-Neck Aneurysm Embolization and Reconstruction Trial: 1-Year Safety and Angiographic Results. AB - BACKGROUND AND PURPOSE: The safety and efficacy of the PulseRider for the treatment of wide-neck, bifurcation aneurysms at the basilar and carotid terminus locations were studied in a prospective trial, the Adjunctive Neurovascular Support of Wide-Neck Aneurysm Embolization and Reconstruction (ANSWER) trial, reporting on initial 6-month angiographic and clinical results. This report provides insight into the longer term durability and safety with 12-month data. MATERIALS AND METHODS: Aneurysms treated with the PulseRider among enrolled sites were prospectively studied. Updated 12-month data on clinical and imaging end points are included. RESULTS: Thirty-four patients were enrolled (29 women, 5 men) with a mean age of 60.9 years. The mean aneurysm height ranged from 2.4 to 15.9 mm with a mean neck size of 5.2 mm (range, 2.3-11.6 mm). At 1 year, there were no device migrations or symptomatic in-stent stenoses. Raymond-Roy I occlusion was achieved in 53% of cases at the time of treatment and progressed to 61% and 67% at 6 and 12 months, respectively. Adequate occlusion (Raymond-Roy I/II) progressed from 88% at 6 months to 90% at 12 months. No recanalizations were observed. There was 1 delayed ischemic event. Good outcome (mRS 0-2) was achieved in 90% of patients. CONCLUSIONS: The updated 1-year results from the ANSWER trial demonstrate aneurysm stability and an acceptable safety profile for aneurysms treated at the basilar apex and carotid terminus. Prospective data from a larger set of aneurysms treated at other locations are required to assess how treatment with PulseRider compares with alternatives for treating wide-neck bifurcation aneurysms.

AB - We describe a 16-year-old boy with mild encephalitis with reversible lesions in the white matter and splenium of corpus callosum as a complication of an influenza B virus infection.

There are several possible causes, including metabolic disorders, hypertension and infection, and the prognosis is usually good, even without treatment. PMID- 29599176 TI - H3K4 Methylation Dependent and Independent Chromatin Regulation by JHD2 and SET1 in Budding Yeast. AB - Set1 and Jhd2 regulate the methylation state of histone H3 lysine-4 (H3K4me) through their opposing methyltransferase and demethylase activities in the budding yeast Saccharomyces cerevisiae H3K4me associates with actively transcribed genes and, like both SET1 and JHD2 themselves, is known to regulate gene expression diversely. It remains unclear, however, if Set1 and Jhd2 act solely through H3K4me. Relevantly, Set1 methylates lysine residues in the kinetochore protein Dam1 while genetic studies of the S. pombe SET1 ortholog suggest the existence of non-H3K4 Set1 targets relevant to gene regulation. We interrogated genetic interactions of JHD2 and SET1 with essential genes involved in varied aspects of the transcription cycle. Our findings implicate JHD2 in genetic inhibition of the histone chaperone complexes Spt16-Pob3 (FACT) and Spt6 Spn1 This targeted screen also revealed that JHD2 inhibits the Nrd1-Nab3-Sen1 (NNS) transcription termination complex. We find that while Jhd2's impact on these transcription regulatory complexes likely acts via H3K4me, Set1 governs the roles of FACT and NNS through opposing H3K4-dependent and -independent functions. We also identify diametrically opposing consequences for mutation of H3K4 to alanine or arginine, illuminating that caution must be taken in interpreting histone mutation studies. Unlike FACT and NNS, detailed genetic studies suggest an H3K4me-centric mode of Spt6-Spn1 regulation by JHD2 and SET1 Chromatin immunoprecipitation and transcript quantification experiments show that Jhd2 opposes the positioning of a Spt6-deposited nucleosome near the transcription start site of SER3, a Spt6-Spn1 regulated gene, leading to hyper-induction of SER3 In addition to confirming and extending an emerging role for Jhd2 in the control of nucleosome occupancy near transcription start sites, our findings suggest some of the chromatin regulatory functions of Set1 are independent of H3K4 methylation.

PMID- 29599177 TI - Teleost Fish-Specific Preferential Retention of Pigmentation Gene-Containing Families After Whole Genome Duplications in Vertebrates. AB - Vertebrate pigmentation is a highly diverse trait mainly determined by neural crest cell derivatives. It has been suggested that two rounds (1R/2R) of whole genome duplications (WGDs) at the basis of vertebrates allowed changes in gene regulation associated with neural crest evolution. Subsequently, the teleost fish lineage experienced other WGDs, including the teleost-specific Ts3R before teleost radiation and the more recent Ss4R at the basis of salmonids. As the teleost lineage harbors the highest number of pigment cell types and pigmentation diversity in vertebrates, WGDs might have contributed to the evolution and diversification of the pigmentation gene repertoire in teleosts. We have compared the impact of the basal vertebrate 1R/2R duplications with that of the teleost specific Ts3R and salmonid-specific Ss4R WGDs on 181 gene families containing genes involved in pigmentation. We show that pigmentation genes (PGs) have been globally more frequently retained as duplicates than other genes after Ts3R and Ss4R but not after the early 1R/2R. This is also true for non-pigmentary paralogs of PGs, suggesting that the function in pigmentation is not the sole key driver of gene retention after WGDs. On the long-term, specific categories of PGs have been repeatedly preferentially retained after ancient 1R/2R and Ts3R WGDs, possibly linked to the molecular nature of their proteins (e.g., DNA binding transcriptional regulators) and their central position in protein-protein interaction networks. Taken together, our results support a major role of WGDs in the diversification of the pigmentation gene repertoire in the teleost lineage, with a possible link with the diversity of pigment cell lineages observed in these animals compared to other vertebrates.

PMID- 29599178 TI - Phospholipid-flipping activity of P4-ATPase drives membrane curvature. AB - P4-ATPases are phospholipid flippases that translocate phospholipids from the exoplasmic/luminal to the cytoplasmic leaflet of biological membranes. All P4 ATPases in yeast and some in other organisms are required for membrane trafficking; therefore, changes in the transbilayer lipid composition induced by flippases are thought to be crucial for membrane deformation. However, it is poorly understood whether the phospholipid-flipping activity of P4-ATPases can promote membrane deformation. In this study, we assessed membrane deformation induced by flippase activity via monitoring the extent of membrane tubulation using a system that allows inducible recruitment of Bin/amphiphysin/Rvs (BAR) domains to the plasma membrane (PM). Enhanced phosphatidylcholine-flippase activity at the PM due to expression of ATP10A, a member of the P4-ATPase family, promoted membrane tubulation upon recruitment of BAR domains to the PM This is the important evidence that changes in the transbilayer lipid composition induced by P4-ATPases can deform biological membranes.

PMID- 29599183 TI - Embolization through the thyrocervical trunk: vascular anatomy, variants, and a case series. AB - BACKGROUND AND PURPOSE: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk. METHODS: A retrospective review of all the interventional radiology procedures carried out through the TCT in our tertiary care center from August 2014 to January 2017 is presented. RESULTS: A total of eight endovascular procedures through the TCT including six preoperative embolizations: three paragangliomas, a cervical vertebral metastasis, a cervical vertebral aneurysmal bone cyst, and a very rare case of nerve root extradural cervical hemangioblastoma, as well as two emergency embolizations: a patient with a cervical traumatic active bleeding hematoma and a recurrent hemoptysis in a single ventricle patient. CONCLUSIONS: A correct knowledge of the vascular anatomy, anatomical variants, and anastomosis (especially with the anterior spinal artery) of the TCT is essential for a safe embolization, both preoperatively and on an emergency basis. In cases of recurrent hemoptysis and severe lower-neck injuries, the TCT should always be reviewed. PMID- 29599184 TI - Rapid diagnosis of pulmonary tuberculosis by combined molecular and immunological methods. AB - Diagnosing pulmonary tuberculosis (TB) may be delayed until culture results become available.We ascertained the accuracy of a stepwise diagnostic algorithm for the rapid diagnosis of pulmonary TB by GeneXpert from sputum and/or bronchoalveolar lavage (BAL) followed by a Mycobacterium tuberculosis-specific BAL ELISPOT assay in patients with a suspected diagnosis of pulmonary TB at a clinical referral centre in Germany.Among 166 patients with a presumptive diagnosis of pulmonary TB, 81 cases were confirmed by M. tuberculosis culture from sputum and/or BAL. In 66 out of 81 (81.5%) cases, patients initially had M. tuberculosis detected by GeneXpert from sputum; in addition, six out of 81 (7.4%) cases were diagnosed by GeneXpert on BAL fluid (together 72 out of 81 (88.9%) patients). Out of the remaining nine patients with negative GeneXpert results from sputum and BAL, BAL ELISPOT identified eight patients with culture-confirmed TB correctly (median time to culture positivity 26 days). At a cut-off of >4000 early secretory antigenic target-6- or culture filtrate protein-10-specific interferon-gamma-producing lymphocytes per 1 000 0000 lymphocytes, the specificity of the BAL ELISPOT for active TB was 97%.In low TB incidence countries, nearly all patients with active pulmonary TB can be identified within the first few days of clinical presentation using a stepwise strategy with GeneXpert and BAL ELISPOT.

PMID- 29599186 TI - In-depth haemodynamic phenotyping of pulmonary hypertension due to left heart disease. AB - The commonest cause of pulmonary hypertension (PH) is left heart disease (LHD). The current classification system for definitions of PH-LHD is under review. We therefore performed prospective in-depth invasive haemodynamic phenotyping in order to assess the site of increased pulmonary vascular resistance (PVR) in PH LHD subsets.Based on pulmonary artery occlusion waveforms yielding an estimate of the effective capillary pressure, we partitioned PVR in larger arterial (Rup, upstream resistance) and small arterial plus venous components (Rds, downstream resistance). In the case of small vessel disease, Rup decreases and Rds increases. Inhaled nitric oxide (NO) testing was used to assess acute vasoreactivity.Right ventricular afterload (PVR, pulmonary arterial compliance and effective arterial elastance) was significantly higher in combined post- and pre-capillary PH (Cpc-PH, n=35) than in isolated post-capillary PH (Ipc-PH, n=20). Right ventricular afterload decreased during inhalation of NO in Cpc-PH and idiopathic pulmonary arterial hypertension (n=31), but remained unchanged in Ipc-PH. Rup was similar in Cpc-PH (66.8+/-10.8%) and idiopathic pulmonary arterial hypertension (65.0+/-12.2%; p=0.530) suggesting small vessel disease, but significantly higher in Ipc-PH (96.5+/-4.5%; p<0.001) suggesting upstream transmission of elevated left atrial pressure.Right ventricular afterload is driven by elevated left atrial pressure in Ipc-PH and is further increased by elevated small vessel resistance in Cpc-PH. Cpc-PH is responsive to inhaled NO. Our data support current definitions of PH-LHD subsets. PMID- 29599187 TI - The in vitro effect of nebulised hypertonic saline on human bronchial epithelium. AB - Inhaled hypertonic saline (HS) is an effective therapy for muco-obstructive lung diseases. However, the mechanism of action and principles pertinent to HS administration remain unclear.An in vitro system aerosolised HS to epithelial cells at rates comparable to in vivo conditions. Airway surface liquid (ASL) volume and cell height responses were measured by confocal microscopy under normal and hyperconcentrated mucus states.Aerosolised HS produced a rapid increase in ASL height and decrease in cell height. Added ASL volume was quickly reabsorbed following termination of nebulisation, although cell height did not recover within the same time frame. ASL volume responses to repeated HS administrations were blunted, but could be restored by a hypotonic saline bolus interposed between HS administrations. HS-induced ASL hydration was prolonged with hyperconcentrated mucus on the airway surface, with more modest reductions in cell volume.Aerosolised HS produced osmotically induced increases in ASL height that were limited by active sodium absorption and cell volume-induced reductions in cell water permeability. Mucus on airway surfaces prolonged the effect of HS via mucus-dependent osmotic forces, suggesting that the duration of action of HS is increased in patients with hyperconcentrated mucus. PMID- 29599188 TI - Prognostic impact of copeptin in pulmonary embolism: a multicentre validation study. AB - To externally validate the prognostic impact of copeptin, either alone or integrated in risk stratification models, in pulmonary embolism (PE), we performed a post hoc analysis of 843 normotensive PE patients prospectively included in three European cohorts.Within the first 30 days, 21 patients (2.5%, 95% CI 1.5-3.8) had an adverse outcome and 12 (1.4%, 95% CI 0.7-2.5) died due to PE. Patients with copeptin >=24 pmol.L-1 had a 6.3-fold increased risk for an adverse outcome (95% CI 2.6-15.5, p<0.001) and a 7.6-fold increased risk for PE related death (95% CI 2.3-25.6, p=0.001). Risk classification according to the 2014 European Society of Cardiology (ESC) guideline algorithm identified 248 intermediate-high-risk patients (29.4%) with 5.6% (95% CI 3.1-9.3) at risk of adverse outcomes. A stepwise biomarker-based risk assessment strategy (based on high-sensitivity troponin T, N-terminal pro-brain natriuretic peptide and copeptin) identified 123 intermediate-high-risk patients (14.6%) with 8.9% (95% CI 4.5-15.4) at risk of adverse outcomes. The identification of patients at higher risk was even better when copeptin was measured on top of the 2014 ESC algorithm in intermediate-high-risk patients (adverse outcome OR 11.1, 95% CI 4.6 27.1, p<0.001; and PE-related death OR 13.5, 95% CI 4.2-43.6, p<0.001; highest risk group versus all other risk groups). This identified 85 patients (10.1%) with 12.9% (95% CI 6.6-22.0) at risk of adverse outcomes and 8.2% (95% CI 3.4 16.2) at risk of PE-related deaths.Copeptin improves risk stratification of normotensive PE patients, especially when identifying patients with an increased risk of an adverse outcome.

AB - Although a variety of affinity purification mass spectrometry (AP-MS) strategies have been used to investigate complex interactions, many of these are susceptible to artifacts because of substantial overexpression of the exogenously expressed bait protein. Here we present a logical and systematic workflow that uses the multifunctional Halo tag to assess the correct localization and behavior of tagged subunits of the Sin3 histone deacetylase complex prior to further AP-MS analysis. Using this workflow, we modified our tagging/expression strategy with 21.7% of the tagged bait proteins that we constructed, allowing us to quickly develop validated reagents. Specifically, we apply the workflow to map interactions between stably expressed versions of the Sin3 subunits SUDS3, SAP30, or SAP30L and other cellular proteins. Here we show that the SAP30 and SAP30L paralogues strongly associate with the core Sin3 complex, but SAP30L has unique associations with the proteasome and the myelin sheath. Next, we demonstrate an advancement of the complex NSAF (cNSAF) approach, in which normalization to the scaffold protein SIN3A accounts for variations in the proportion of each bait capturing Sin3 complexes and allows a comparison among different baits capturing the same protein complex. This analysis reveals that although the Sin3 subunit SUDS3 appears to be used in both SIN3A and SIN3B based complexes, the SAP30 subunit is not used in SIN3B based complexes. Intriguingly, we do not detect the Sin3 subunits SAP18 and SAP25 among the 128 high-confidence interactions identified, suggesting that these subunits may not be common to all versions of the Sin3 complex in human cells. This workflow provides the framework for building validated reagents to assemble quantitative interaction networks for chromatin remodeling complexes and provides novel insights into focused protein interaction networks. PMID- 29599191 TI - AP-SWATH Reveals Direct Involvement of VCP/p97 in Integrated Stress Response Signaling Through Facilitating CReP/PPP1R15B Degradation. AB - The ubiquitin-directed AAA-ATPase VCP/p97 facilitates degradation of damaged or misfolded proteins in diverse cellular stress response pathways. Resolving the complexity of its interactions with partner and substrate proteins and understanding its links to stress signaling is therefore a major challenge. Here, we used affinity-purification SWATH mass spectrometry (AP-SWATH) to identify proteins that specifically interact with the substrate-trapping mutant, p97 E578Q. AP-SWATH identified differential interactions over a large detection range from abundant p97 cofactors to pathway-specific partners and individual ligases such as RNF185 and MUL1 that were trapped in p97-E578Q complexes. In addition, we identified various substrate proteins and candidates including the PP1 regulator CReP/PPP1R15B that dephosphorylates eIF2alpha and thus counteracts attenuation of translation by stress-kinases. We provide evidence that p97 with its Ufd1-Npl4 adapter ensures rapid constitutive turnover and balanced levels of CReP in unperturbed cells. Moreover, we show that p97-mediated degradation, together with a reduction in CReP synthesis, is essential for timely stress-induced reduction of CReP levels and, consequently, for robust eIF2alpha phosphorylation to enforce the stress response. Thus, our results demonstrate that p97 not only facilitates bulk degradation of misfolded proteins upon stress, but also directly modulates the integrated stress response at the level of signaling. PMID- 29599192 TI - Imaging of nonlocal hot-electron energy dissipation via shot noise. AB - In modern microelectronic devices, hot electrons accelerate, scatter, and dissipate energy in nanoscale dimensions. Despite recent progress in nanothermometry, direct real-space mapping of hot-electron energy dissipation is challenging because existing techniques are restricted to probing the lattice rather than the electrons. We realize electronic nanothermometry by measuring local current fluctuations, or shot noise, associated with ultrafast hot-electron kinetic processes (~21 terahertz). Exploiting a scanning and contact-free tungsten tip as a local noise probe, we directly visualize hot-electron distributions before their thermal equilibration with the host gallium arsenide/aluminium gallium arsenide crystal lattice. With nanoconstriction devices, we reveal unexpected nonlocal energy dissipation at room temperature, which is reminiscent of ballistic transport of low-temperature quantum conductors. PMID- 29599193 TI - Pulmonary neuroendocrine cells amplify allergic asthma responses. AB - Pulmonary neuroendocrine cells (PNECs) are rare airway epithelial cells whose function is poorly understood. Here we show that Ascl1-mutant mice that have no PNECs exhibit severely blunted mucosal type 2 response in models of allergic asthma. PNECs reside in close proximity to group 2 innate lymphoid cells (ILC2s) near airway branch points. PNECs act through calcitonin gene-related peptide (CGRP) to stimulate ILC2s and elicit downstream immune responses. In addition, PNECs act through the neurotransmitter gamma-aminobutyric acid (GABA) to induce goblet cell hyperplasia. The instillation of a mixture of CGRP and GABA in Ascl1 mutant airways restores both immune and goblet cell responses. In accordance, lungs from human asthmatics show increased PNECs. These findings demonstrate that the PNEC-ILC2 neuroimmunological modules function at airway branch points to amplify allergic asthma responses.

AB - Activated immune cells undergo a metabolic switch to aerobic glycolysis akin to the Warburg effect, thereby presenting a potential therapeutic target in autoimmune disease. Dimethyl fumarate (DMF), a derivative of the Krebs cycle intermediate fumarate, is an immunomodulatory drug used to treat multiple sclerosis and psoriasis. Although its therapeutic mechanism remains uncertain, DMF covalently modifies cysteine residues in a process termed succination. We found that DMF succinates and inactivates the catalytic cysteine of the glycolytic enzyme glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in mice and humans, both in vitro and in vivo. It thereby down-regulates aerobic glycolysis in activated myeloid and lymphoid cells, which mediates its anti-inflammatory effects. Our results provide mechanistic insight into immune modulation by DMF and represent a proof of concept that aerobic glycolysis is a therapeutic target in autoimmunity. PMID- 29599195 TI - 2-O, 3-O desulfated heparin mitigates murine chemotherapy- and radiation-induced thrombocytopenia. AB - Thrombocytopenia is a significant complication of chemotherapy and radiation therapy. Platelet factor 4 (PF4; CXCL4) is a negative paracrine of megakaryopoiesis. We have shown that PF4 levels are inversely related to steady state platelet counts, and to the duration and severity of chemotherapy- and radiation-induced thrombocytopenia (CIT and RIT, respectively). Murine studies suggest that blocking the effect of PF4 improves megakaryopoiesis, raising nadir platelet counts and shortening the time to platelet count recovery. We examined the ability of 2-O, 3-O desulfated heparin (ODSH), a heparin variant with little anticoagulant effects, to neutralize PF4's effects on megakaryopoiesis. Using megakaryocyte colony assays and liquid cultures, we show that ODSH restored megakaryocyte proliferation in PF4-treated Cxcl4-/- murine and human CD34+ derived megakaryocyte cultures (17.4% megakaryocyte colonies, P < .01 compared with PF4). In murine CIT and RIT models, ODSH, started 24 hours after injury, was examined for the effect on hematopoietic recovery demonstrating higher platelet count nadirs (9% +/- 5% treated vs 4% +/- 4% control) and significantly improved survival in treated animals (73% treated vs 36% control survival). Treatment with ODSH was able to reduce intramedullary free PF4 concentrations by immunohistochemical analysis. In summary, ODSH mitigated CIT and RIT in mice by neutralizing the intramedullary negative paracrine PF4. ODSH, already in clinical trials in humans as an adjuvant to chemotherapy, may be an important, clinically relevant therapeutic for CIT and RIT. PMID- 29599197 TI - Telephone consultations. PMID- 29599199 TI - A lung full of Cheerios. PMID- 29599198 TI - Acceptance of Routine HIV Testing by Hospitalized Adolescents and Young Adults. AB - BACKGROUND AND OBJECTIVES: Youth carry a disproportionate burden of new HIV infections. With our study, we aimed to characterize HIV testing experiences among adolescents and young adults admitted to a children's hospital that is located in a high HIV-prevalent community and implemented routine HIV testing for all patients >=13 years of age. METHODS: A total of 120 patients aged 13 to 24 years old who were admitted to our hospital and had a documented offer of routine HIV testing on admission were invited to complete a self-administered survey that asked about sex, race and/or ethnicity, HIV risk behaviors, and attitudes toward routine HIV testing in the hospital. Date of birth, admission diagnosis, and verification of HIV testing and results were collected by chart review. RESULTS: Study participants (N = 99) were 17.4 +/- 2.3 years old, 52% female, 47% Hispanic, and 29% African American. Additional characteristics include the following: 65% had previous sexual activity, 11% had a history of sexually transmitted infections, and 12% were worried about their risk for HIV. Forty seven percent of participants accepted HIV testing, with older patients (P < .01) and those reporting previous sexual activity (P < .01) and a previous HIV test (P < .01) being more likely to accept testing. A total of 96% of participants agreed that the hospital is a good place to offer HIV testing. CONCLUSIONS: Our findings support offering routine HIV testing to youth admitted to children's hospital. Given the high incidence of new and undiagnosed HIV infections among youth, additional venues for HIV testing are essential. PMID- 29599200 TI - The outcome of peripheral T-cell lymphoma patients failing first-line therapy: a report from the prospective, International T-Cell Project. AB - This analysis explored factors influencing survival of patients with primary refractory and relapsed peripheral T-cell lymphomas enrolled in the prospective International T-cell Project. We analyzed data from 1020 patients with newly diagnosed disease, enrolled between September 2006 and December 2015. Out of 937 patients who received first-line treatment, 436 (47%) were identified as refractory and 197 (21%) as relapsed. Median time from the end of treatment to relapse was 8 months (range 2-73). Overall, 75 patients (8%) were consolidated with bone marrow transplantation, including 12 refractory and 22 relapsed patients. After a median follow up of 38 months (range 1-96 months) from documentation of refractory/relapsed disease, 440 patients had died. The median overall survival (OS) was 5.8 months; 3-year overall survival rates were 21% and 28% for refractory and relapsed patients, respectively (P<0.001). Patients receiving or not salvage bone marrow transplantation had a 3-year survival of 48% and 18%, respectively (P<0.001). In a univariate Cox regression analysis, refractory disease was associated with a higher risk of death (HR=1.43, P=0.001), whereas late relapse (>12 months, HR 0.57, P=0.001) and salvage therapy with transplantation (HR=0.36, P<0.001) were associated with a better OS. No difference was found in OS with respect to histology. This study accurately reflects outcomes for patients treated according to standards of care worldwide. Results confirm that peripheral T-cell lymphomas patients had dismal outcome after relapse or progression. Patients with chemotherapy sensitive disease who relapsed after more than 12 months might benefit from consolidation bone marrow transplantation. PMID- 29599201 TI - The chromatin-remodeling factor CHD4 is required for maintenance of childhood acute myeloid leukemia. AB - Epigenetic alterations contribute to leukemogenesis in childhood acute myeloid leukemia and therefore are of interest for potential therapeutic strategies. Herein, we performed large-scale ribonucleic acid interference screens using small hairpin ribonucleic acids in acute myeloid leukemia cells and non transformed bone marrow cells to identify leukemia-specific dependencies. One of the target genes displaying the strongest effects on acute myeloid leukemia cell growth and less pronounced effects on nontransformed bone marrow cells, was the chromatin remodeling factor CHD4 Using ribonucleic acid interference and CRISPR Cas9 approaches, we showed that CHD4 was essential for cell growth of leukemic cells in vitro and in vivo Loss of function of CHD4 in acute myeloid leukemia cells caused an arrest in the G0 phase of the cell cycle as well as downregulation of MYC and its target genes involved in cell cycle progression. Importantly, we found that inhibition of CHD4 conferred anti-leukemic effects on primary childhood acute myeloid leukemia cells and prevented disease progression in a patient-derived xenograft model. Conversely, CHD4 was not required for growth of normal hematopoietic cells. Taken together, our results identified CHD4 as a potential therapeutic target in childhood acute myeloid leukemia.

AB - In this retrospective study, we evaluate long-term complications in nearly all beta-thalassemia-major patients who successfully received allogeneic hematopoietic stem cell transplantation in France. Ninety-nine patients were analyzed with a median age of 5.9 years at transplantation. The median duration of clinical follow up was 12 years. All conditioning regimens were myeloablative, most were based on busulfan combined with cyclophosphamide, and more than 90% of patients underwent a transplant from a matched sibling donor. After transplantation, 11% of patients developed thyroid dysfunction, 5% diabetes, and 2% heart failure. Hypogonadism was present in 56% of females and 14% of males. Female patients who went on to normal puberty after transplant were significantly younger at transplantation than those who experienced delayed puberty (median age 2.5 vs 8.7 years). Fertility was preserved in 9 of 27 females aged 20 years or older and 2 other patients became pregnant following oocyte donation. In addition to patient's age and higher serum ferritin levels at transplantation, time elapsed since transplant was significantly associated with decreased height growth in multivariate analysis. Weight growth increased after transplantation particularly in females, 36% of adults being overweight at last evaluation. A comprehensive long-term monitoring, especially of endocrine late effects, is required after hematopoietic stem cell transplantation for thalassemia. PMID- 29599207 TI - Rise in GPs taking early retirement. PMID- 29599205 TI - Recurring mutations in RPL15 are linked to hydrops fetalis and treatment independence in Diamond-Blackfan anemia. AB - Diamond-Blackfan anemia (DBA) is a rare inherited bone marrow failure disorder linked predominantly to ribosomal protein gene mutations. Here the European DBA consortium reports novel mutations identified in the RPL15 gene in 6 unrelated individuals diagnosed with DBA. Although point mutations have not been previously reported for RPL15, we identified 4 individuals with truncating mutations p.Tyr81* (in 3 of 4) and p.Gln29*, and 2 with missense variants p.Leu10Pro and p.Lys153Thr. Notably, 75% (3 of 4) of truncating mutation carriers manifested with severe hydrops fetalis and required intrauterine transfusions. Even more remarkable is the observation that the 3 carriers of p.Tyr81* mutation became treatment-independent between four and 16 months of life and maintained normal blood counts until their last follow up. Genetic reversion at the DNA level as a potential mechanism of remission was not observed in our patients. In vitro studies revealed that cells carrying RPL15 mutations have pre-rRNA processing defects, reduced 60S ribosomal subunit formation, and severe proliferation defects. Red cell culture assays of RPL15-mutated primary erythroblast cells also showed a severe reduction in cell proliferation, delayed erythroid differentiation, elevated TP53 activity, and increased apoptosis. This study identifies a novel subgroup of DBA with mutations in the RPL15 gene with an unexpected high rate of hydrops fetalis and spontaneous, long-lasting remission. PMID- 29599206 TI - Impact of hydroxycarbamide and interferon-alpha on red cell adhesion and membrane protein expression in polycythemia vera. AB - Polycythemia vera is a chronic myeloproliferative neoplasm characterized by the JAK2V617F mutation, elevated blood cell counts and a high risk of thrombosis. Although the red cell lineage is primarily affected by JAK2V617F, the impact of mutated JAK2 on circulating red blood cells is poorly documented. Recently, we showed that in polycythemia vera, erythrocytes had abnormal expression of several proteins including Lu/BCAM adhesion molecule and proteins from the endoplasmic reticulum, mainly calreticulin and calnexin. Here we investigated the effects of hydroxycarbamide and interferon-alpha treatments on the expression of erythroid membrane proteins in a cohort of 53 patients. Surprisingly, while both drugs tended to normalize calreticulin expression, proteomics analysis showed that hydroxycarbamide deregulated the expression of 53 proteins in red cell ghosts, with overexpression and downregulation of 37 and 16 proteins, respectively. Within over-expressed proteins, hydroxycarbamide was found to enhance the expression of adhesion molecules such as Lu/BCAM and CD147, while interferon alpha did not. In addition, we found that hydroxycarbamide increased Lu/BCAM phosphorylation and exacerbated red cell adhesion to its ligand laminin. Our study reveals unexpected adverse effects of hydroxycarbamide on red cell physiology in polycythemia vera and provides new insights into the effects of this molecule on gene regulation and protein recycling or maturation during erythroid differentiation. Furthermore, our study shows deregulation of Lu/BCAM and CD147 that are two ubiquitously expressed proteins linked to progression of solid tumors, paving the way for future studies to address the role of hydroxycarbamide in tissues other than blood cells in myeloproliferative neoplasms. PMID- 29599209 TI - Optimal ventilator strategies for trauma-related ARDS. AB - BACKGROUND: Acute respiratory distress syndrome (ARDS) was first described in the 1960s and has become a major area of research due to the mortality and morbidity associated with it. ARDS is currently defined using the Berlin Consensus; however, this is not wholly applicable for trauma-related ARDS. METHODS: A systematic review of the literature was undertaken using the Preferred Reporting for Systematic Reviews and Meta Analyses methodology. The Ovid Medline, Web of Science and PubMed online databases were interrogated for papers published between 1 January 1995 and 31 December 2017. RESULTS: The literature search yielded a total of 64 papers that fulfilled the search criteria. CONCLUSIONS: Despite decades of dedicated research into different treatment modalities, ARDS continues to carry a high burden of mortality. The ARDS definitions laid out in the Berlin consensus are not entirely suited to trauma. While trauma-related ARDS represents a small portion of the available research, the evidence continues to favour low tidal volume ventilation as the benchmark for current practice. Positive end expiratory ventilation and airway pressure release ventilation in trauma cohorts may be beneficial; however, the evidence to date does not show this. PMID- 29599208 TI - Lgr5+ intestinal stem cells reside in an unlicensed G1 phase. AB - During late mitosis and the early G1 phase, the origins of replication are licensed by binding to double hexamers of MCM2-7. In this study, we investigated how licensing and proliferative commitment are coupled in the epithelium of the small intestine. We developed a method for identifying cells in intact tissue containing DNA-bound MCM2-7. Interphase cells above the transit-amplifying compartment had no DNA-bound MCM2-7, but still expressed the MCM2-7 protein, suggesting that licensing is inhibited immediately upon differentiation. Strikingly, we found most proliferative Lgr5+ stem cells are in an unlicensed state. This suggests that the elongated cell-cycle of intestinal stem cells is caused by an increased G1 length, characterized by dormant periods with unlicensed origins. Significantly, the unlicensed state is lost in Apc-mutant epithelium, which lacks a functional restriction point, causing licensing immediately upon G1 entry. We propose that the unlicensed G1 phase of intestinal stem cells creates a temporal window when proliferative fate decisions can be made. PMID- 29599210 TI - Safe burn excision prior to military repatriation: an achievable goal? AB - Burn excision is the gold standard treatment for full thickness and some deep partial thickness burns. Early burn excision (24-96 hours) has been shown to improve patient outcomes. However, in the military setting, transporting the patient to a centre which can provide this procedure can be delayed. Especially as control of airspace in the future may be hampered due to the political landscape. For this reason, focus on how to achieve safer burn excision prior to repatriation should be addressed. This paper considers the barriers to early burn excision in the military setting and offers potential solutions for the future. PMID- 29599211 TI - Experimental Right Ventricular Hypertension Induces Regional beta1-Integrin Mediated Transduction of Hypertrophic and Profibrotic Right and Left Ventricular Signaling. AB - BACKGROUND: Development of right ventricular (RV) hypertension eventually contributes to RV and left ventricular (LV) myocardial fibrosis and dysfunction. The molecular mechanisms are not fully elucidated. METHODS AND RESULTS: Pulmonary artery banding was used to induce RV hypertension in rats in vivo. Then, we evaluated cardiac function and regional remodeling 6 weeks after pulmonary artery banding. To further elucidate mechanisms responsible for regional cardiac remodeling, we also mimicked RV hypertensive stress by cyclic mechanical stretching applied to confluent cultures of cardiac fibroblasts, isolated from the RV free wall, septal hinge points, and LV free wall. Echocardiography and catheter evaluation demonstrated that rats in the pulmonary artery banding group developed RV hypertension with leftward septal displacement, LV compression, and increased LV end-diastolic pressures. Picrosirius red staining indicated that pulmonary artery banding induced marked RV fibrosis and dysfunction, with prominent fibrosis and elastin deposition at the septal hinge points but less LV fibrosis. These changes were associated with proportionally increased expressions of integrin-beta1 and profibrotic signaling proteins, including phosphorylated Smad2/3 and transforming growth factor-beta1. Moreover, mechanically stretched fibroblasts also expressed significantly increased levels of alpha-smooth muscle actin, integrin-beta1, transforming growth factor-beta1, collagen I deposition, and wrinkle formation on gel assays, consistent with myofibroblast transformation. These changes were not observed in parallel cultures of mechanically stretched fibroblasts, preincubated with the integrin inhibitor (BTT 3033). CONCLUSIONS: Experimentally induced RV hypertension triggers regional RV, hinge-point, and LV integrin beta1-dependent mechanotransduction signaling pathways that eventually trigger myocardial fibrosis via transforming growth factor-beta1 signaling. Reduced LV fibrosis and preserved global function, despite geometrical and pressure aberrations, suggest a possible elastin-mediated protective mechanism at the septal hinge points.

AB - Horner and Pohl argue that high water transport rates reported for carbon nanotube porins (CNTPs) originate from leakage at the nanotube-bilayer interface. Our results and new experimental evidence are consistent with transport through the nanotube pores and rule out a defect-mediated transport mechanism. Mechanistic origins of the high Arrhenius factor that we reported for narrow CNTPs at pH 8 require further investigation. PMID- 29599215 TI - Comment on "Enhanced water permeability and tunable ion selectivity in subnanometer carbon nanotube porins". AB - Tunuguntla et al (Reports, 25 August 2017, p. 792) report that permeation of single-file water occurs faster through carbon nanotubes than through aquaporins. We show that this conclusion violates fundamental thermodynamic laws: Because of its much lower activation energy, aquaporin-mediated water transport must be orders of magnitude faster. Leakage at the nanotube-membrane interface may explain the discrepancy. PMID- 29599213 TI - Structure of the nucleotide exchange factor eIF2B reveals mechanism of memory enhancing molecule. AB - Regulation by the integrated stress response (ISR) converges on the phosphorylation of translation initiation factor eIF2 in response to a variety of stresses. Phosphorylation converts eIF2 from a substrate to a competitive inhibitor of its dedicated guanine nucleotide exchange factor, eIF2B, thereby inhibiting translation. ISRIB, a drug-like eIF2B activator, reverses the effects of eIF2 phosphorylation, and in rodents it enhances cognition and corrects cognitive deficits after brain injury. To determine its mechanism of action, we solved an atomic-resolution structure of ISRIB bound in a deep cleft within decameric human eIF2B by cryo-electron microscopy. Formation of fully active, decameric eIF2B holoenzyme depended on the assembly of two identical tetrameric subcomplexes, and ISRIB promoted this step by cross-bridging a central symmetry interface. Thus, regulation of eIF2B assembly emerges as a rheostat for eIF2B activity that tunes translation during the ISR and that can be further modulated by ISRIB.

AB - Reduction of N2 by nitrogenases occurs at an organometallic iron cofactor that commonly also contains either molybdenum or vanadium. The well-characterized resting state of the cofactor does not bind substrate, so its mode of action remains enigmatic. Carbon monoxide was recently found to replace a bridging sulfide, but the mechanistic relevance was unclear. Here we report the structural analysis of vanadium nitrogenase with a bound intermediate, interpreted as a MU2 bridging, protonated nitrogen that implies the site and mode of substrate binding to the cofactor. Binding results in a flip of amino acid glutamine 176, which hydrogen-bonds the ligand and creates a holding position for the displaced sulfide. The intermediate likely represents state E6 or E7 of the Thorneley-Lowe model and provides clues to the remainder of the catalytic cycle. PMID- 29599236 TI - Carbothermal shock synthesis of high-entropy-alloy nanoparticles. AB - The controllable incorporation of multiple immiscible elements into a single nanoparticle merits untold scientific and technological potential, yet remains a challenge using conventional synthetic techniques. We present a general route for alloying up to eight dissimilar elements into single-phase solid-solution nanoparticles, referred to as high-entropy-alloy nanoparticles (HEA-NPs), by thermally shocking precursor metal salt mixtures loaded onto carbon supports [temperature ~2000 kelvin (K), 55-millisecond duration, rate of ~105 K per second]. We synthesized a wide range of multicomponent nanoparticles with a desired chemistry (composition), size, and phase (solid solution, phase separated) by controlling the carbothermal shock (CTS) parameters (substrate, temperature, shock duration, and heating/cooling rate). To prove utility, we synthesized quinary HEA-NPs as ammonia oxidation catalysts with ~100% conversion and >99% nitrogen oxide selectivity over prolonged operations. PMID- 29599237 TI - Adaptive infrared-reflecting systems inspired by cephalopods. AB - Materials and systems that statically reflect radiation in the infrared region of the electromagnetic spectrum underpin the performance of many entrenched technologies, including building insulation, energy-conserving windows, spacecraft components, electronics shielding, container packaging, protective clothing, and camouflage platforms. The development of their adaptive variants, in which the infrared-reflecting properties dynamically change in response to external stimuli, has emerged as an important unmet scientific challenge. By drawing inspiration from cephalopod skin, we developed adaptive infrared reflecting platforms that feature a simple actuation mechanism, low working temperature, tunable spectral range, weak angular dependence, fast response, stability to repeated cycling, amenability to patterning and multiplexing, autonomous operation, robust mechanical properties, and straightforward manufacturability. Our findings may open opportunities for infrared camouflage and other technologies that regulate infrared radiation. PMID- 29599238 TI - Activation of olefins via asymmetric Bronsted acid catalysis. AB - The activation of olefins for asymmetric chemical synthesis traditionally relies on transition metal catalysts. In contrast, biological enzymes with Bronsted acidic sites of appropriate strength can protonate olefins and thereby generate carbocations that ultimately react to form natural products. Although chemists have recently designed chiral Bronsted acid catalysts to activate imines and carbonyl compounds, mimicking these enzymes to protonate simple olefins that then engage in asymmetric catalytic reactions has remained a substantial synthetic challenge. Here, we show that a class of confined and strong chiral Bronsted acids enables the catalytic asymmetric intramolecular hydroalkoxylation of unbiased olefins. The methodology gives rapid access to biologically active 1,1 disubstituted tetrahydrofurans, including (-)-Boivinianin A. PMID- 29599239 TI - Nanofluidic rocking Brownian motors. AB - Control and transport of nanoscale objects in fluids is challenging because of the unfavorable scaling of most interaction mechanisms to small length scales. We designed energy landscapes for nanoparticles by accurately shaping the geometry of a nanofluidic slit and exploiting the electrostatic interaction between like charged particles and walls. Directed transport was performed by combining asymmetric potentials with an oscillating electric field to achieve a rocking Brownian motor. Using gold spheres 60 nanometers in diameter, we investigated the physics of the motor with high spatiotemporal resolution, enabling a parameter free comparison with theory. We fabricated a sorting device that separates 60- and 100-nanometer particles in opposing directions within seconds. Modeling suggests that the device separates particles with a radial difference of 1 nanometer. PMID- 29599240 TI - Chameleon-like elastomers with molecularly encoded strain-adaptive stiffening and coloration. AB - Active camouflage is widely recognized as a soft-tissue feature, and yet the ability to integrate adaptive coloration and tissuelike mechanical properties into synthetic materials remains elusive. We provide a solution to this problem by uniting these functions in moldable elastomers through the self-assembly of linear-bottlebrush-linear triblock copolymers. Microphase separation of the architecturally distinct blocks results in physically cross-linked networks that display vibrant color, extreme softness, and intense strain stiffening on par with that of skin tissue. Each of these functional properties is regulated by the structure of one macromolecule, without the need for chemical cross-linking or additives. These materials remain stable under conditions characteristic of internal bodily environments and under ambient conditions, neither swelling in bodily fluids nor drying when exposed to air. PMID- 29599241 TI - Self-heating-induced healing of lithium dendrites. AB - Lithium (Li) metal electrodes are not deployable in rechargeable batteries because electrochemical plating and stripping invariably leads to growth of dendrites that reduce coulombic efficiency and eventually short the battery. It is generally accepted that the dendrite problem is exacerbated at high current densities. Here, we report a regime for dendrite evolution in which the reverse is true. In our experiments, we found that when the plating and stripping current density is raised above ~9 milliamperes per square centimeter, there is substantial self-heating of the dendrites, which triggers extensive surface migration of Li. This surface diffusion heals the dendrites and smoothens the Li metal surface. We show that repeated doses of high-current-density healing treatment enables the safe cycling of Li-sulfur batteries with high coulombic efficiency. PMID- 29599242 TI - Shifts in disease dynamics in a tropical amphibian assemblage are not due to pathogen attenuation. AB - Infectious diseases rarely end in extinction. Yet the mechanisms that explain how epidemics subside are difficult to pinpoint. We investigated host-pathogen interactions after the emergence of a lethal fungal pathogen in a tropical amphibian assemblage. Some amphibian host species are recovering, but the pathogen is still present and is as pathogenic today as it was almost a decade ago. In addition, some species have defenses that are more effective now than they were before the epidemic. These results suggest that host recoveries are not caused by pathogen attenuation and may be due to shifts in host responses. Our findings provide insights into the mechanisms underlying disease transitions, which are increasingly important to understand in an era of emerging infectious diseases and unprecedented global pandemics. PMID- 29599243 TI - Erythrocytic ferroportin reduces intracellular iron accumulation, hemolysis, and malaria risk. AB - Malaria parasites invade red blood cells (RBCs), consume copious amounts of hemoglobin, and severely disrupt iron regulation in humans. Anemia often accompanies malaria disease; however, iron supplementation therapy inexplicably exacerbates malarial infections. Here we found that the iron exporter ferroportin (FPN) was highly abundant in RBCs, and iron supplementation suppressed its activity. Conditional deletion of the Fpn gene in erythroid cells resulted in accumulation of excess intracellular iron, cellular damage, hemolysis, and increased fatality in malaria-infected mice. In humans, a prevalent FPN mutation, Q248H (glutamine to histidine at position 248), prevented hepcidin-induced degradation of FPN and protected against severe malaria disease. FPN Q248H appears to have been positively selected in African populations in response to the impact of malaria disease. Thus, FPN protects RBCs against oxidative stress and malaria infection. PMID- 29599244 TI - Molecular mechanism of extreme mechanostability in a pathogen adhesin. AB - High resilience to mechanical stress is key when pathogens adhere to their target and initiate infection. Using atomic force microscopy-based single-molecule force spectroscopy, we explored the mechanical stability of the prototypical staphylococcal adhesin SdrG, which targets a short peptide from human fibrinogen beta. Steered molecular dynamics simulations revealed, and single-molecule force spectroscopy experiments confirmed, the mechanism by which this complex withstands forces of over 2 nanonewtons, a regime previously associated with the strength of a covalent bond. The target peptide, confined in a screwlike manner in the binding pocket of SdrG, distributes forces mainly toward the peptide backbone through an intricate hydrogen bond network. Thus, these adhesins can attach to their target with exceptionally resilient mechanostability, virtually independent of peptide side chains. PMID- 29599245 TI - Binding of ISRIB reveals a regulatory site in the nucleotide exchange factor eIF2B. AB - The integrated stress response (ISR) is a conserved translational and transcriptional program affecting metabolism, memory, and immunity. The ISR is mediated by stress-induced phosphorylation of eukaryotic translation initiation factor 2alpha (eIF2alpha) that attenuates the guanine nucleotide exchange factor eIF2B. A chemical inhibitor of the ISR, ISRIB, reverses the attenuation of eIF2B by phosphorylated eIF2alpha, protecting mice from neurodegeneration and traumatic brain injury. We describe a 4.1-angstrom-resolution cryo-electron microscopy structure of human eIF2B with an ISRIB molecule bound at the interface between the beta and delta regulatory subunits. Mutagenesis of residues lining this pocket altered the hierarchical cellular response to ISRIB analogs in vivo and ISRIB binding in vitro. Our findings point to a site in eIF2B that can be exploited by ISRIB to regulate translation. PMID- 29599248 TI - Figuring out how I belong. PMID- 29599246 TI - Antibody-mediated inhibition of MICA and MICB shedding promotes NK cell-driven tumor immunity. AB - MICA and MICB are expressed by many human cancers as a result of cellular stress, and can tag cells for elimination by cytotoxic lymphocytes through natural killer group 2D (NKG2D) receptor activation. However, tumors evade this immune recognition pathway through proteolytic shedding of MICA and MICB proteins. We rationally designed antibodies targeting the MICA alpha3 domain, the site of proteolytic shedding, and found that these antibodies prevented loss of cell surface MICA and MICB by human cancer cells. These antibodies inhibited tumor growth in multiple fully immunocompetent mouse models and reduced human melanoma metastases in a humanized mouse model. Antitumor immunity was mediated mainly by natural killer (NK) cells through activation of NKG2D and CD16 Fc receptors. This approach prevents the loss of important immunostimulatory ligands by human cancers and reactivates antitumor immunity. PMID- 29599250 TI - Treating those committed to your care. PMID- 29599247 TI - Destabilizing mutations encode nongenetic variation that drives evolutionary innovation. AB - Evolutionary innovations are often achieved by repurposing existing genes to perform new functions; however, the mechanisms enabling the transition from old to new remain controversial. We identified mutations in bacteriophage lambda's host-recognition gene J that confer enhanced adsorption to lambda's native receptor, LamB, and the ability to access a new receptor, OmpF. The mutations destabilize lambda particles and cause conformational bistability of J, which yields progeny of multiple phenotypic forms, each proficient at different receptors. This work provides an example of how nongenetic protein variation can catalyze an evolutionary innovation. We propose that cases where a single genotype can manifest as multiple phenotypes may be more common than previously expected and offer a general mechanism for evolutionary innovation. PMID- 29599249 TI - Acute retinal toxicity associated with a mixture of perfluorooctane and perfluorohexyloctane: failure of another indirect cytotoxicity analysis. AB - AIMS: To report new information related to acute retinal toxicity of Bio Octane Plus, a mixture of 90% perfluorooctane (PFO) and 10% perfluorohexyloctane. METHODS: This retrospective, descriptive case series reports the occurrence of acute retinal toxicity after vitreoretinal surgery in which Bio Octane Plus (batch number 1605148) was used as an endotamponade. Cytotoxicity biocompatibility tests and chemical analyses by Fourier-transformed infrared (FTIR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) of the presumed toxic product were performed. RESULTS: Four patients presented with acute severe visual loss after uneventful ocular surgery assisted by Bio Octane Plus (batch number 1605148) as endotamponade. Patients experienced extensive retinal vascular occlusion leading to retinal and optic nerve atrophy. The viability of ARPE-19 cells directly exposed to the suspect batch for 30 min was 0%. The agarose overlay method used by the manufacturer according to European Union regulations and International Organization for Standardization (ISO) International Standards failed to detect toxicity. FTIR spectroscopy showed small differences between the non-toxic and toxic batches. GC-MS analysis showed the presence of bromotributyl stannane (whose toxicity was demonstrated in the dose response curve) only in the toxic batch of Bio Octane Plus. CONCLUSION: This is the third report of retinotoxicity due to PFO in 4 years. The clinical profiles may be missed as they resemble other postsurgical complications; therefore, more cases worldwide could have gone unreported. Protocols to determine cytotoxicity of intraocular medical devices and approved by the ISO International Standards based on indirect methods have failed and should be revised to ensure safety.

PMID- 29599268 TI - Temporal-Specific Interaction of NF-YC and CURLY LEAF during the Floral Transition Regulates Flowering. AB - The flowering time of higher plants is controlled by environmental cues and intrinsic signals. In Arabidopsis (Arabidopsis thaliana), flowering is accelerated by exposure to long-day conditions via the key photoperiod-induced factor FLOWERING LOCUS T (FT). Nuclear Factor-Y subunit C (NF-YC) proteins function as important mediators of epigenetic marks in different plant developmental stages and play an important role in the regulation of FT transcription, but the mechanistic details of this remain unknown. In this study, we show that Arabidopsis NF-YC homologs temporally interact with the histone methyltransferase CURLY LEAF (CLF) during the flowering transition. The binding of NF-YC antagonizes the association of CLF with chromatin and the CLF-dependent deposition of H3 lysine-27 trimethylation, thus relieving the repression of FT transcription and facilitating flowering under long-day conditions. Our findings reveal a novel mechanism of NF-YC/CLF-mediated epigenetic regulation of FT activation in photoperiod-induced flowering and, consequently, contribute to our understanding of how plants control developmental events in a temporal-specific regulatory manner.

AB - As part of the TACTICS (Transnational Alliance for Regenerative Therapies in Cardiovascular Syndromes) series to enhance regenerative medicine, here, we discuss the role of preclinical studies designed to advance stem cell therapies for cardiovascular disease. The quality of this research has improved over the past 10 to 15 years and overall indicates that cell therapy promotes cardiac repair. However, many issues remain, including inability to provide complete cardiac recovery. Recent studies question the need for intact cells suggesting that harnessing what the cells release is the solution. Our contribution describes important breakthroughs and current directions in a cell-based approach to alleviating cardiovascular disease. PMID- 29599278 TI - Standards and Methodological Rigor in Pulmonary Arterial Hypertension Preclinical and Translational Research. AB - Despite advances in our understanding of the pathophysiology and the management of pulmonary arterial hypertension (PAH), significant therapeutic gaps remain for this devastating disease. Yet, few innovative therapies beyond the traditional pathways of endothelial dysfunction have reached clinical trial phases in PAH. Although there are inherent limitations of the currently available models of PAH, the leaky pipeline of innovative therapies relates, in part, to flawed preclinical research methodology, including lack of rigour in trial design, incomplete invasive hemodynamic assessment, and lack of careful translational studies that replicate randomized controlled trials in humans with attention to adverse effects and benefits. Rigorous methodology should include the use of prespecified eligibility criteria, sample sizes that permit valid statistical analysis, randomization, blinded assessment of standardized outcomes, and transparent reporting of results. Better design and implementation of preclinical studies can minimize inherent flaws in the models of PAH, reduce the risk of bias, and enhance external validity and our ability to distinguish truly promising therapies form many false-positive or overstated leads. Ideally, preclinical studies should use advanced imaging, study several preclinical pulmonary hypertension models, or correlate rodent and human findings and consider the fate of the right ventricle, which is the major determinant of prognosis in human PAH. Although these principles are widely endorsed, empirical evidence suggests that such rigor is often lacking in pulmonary hypertension preclinical research. The present article discusses the pitfalls in the design of preclinical pulmonary hypertension trials and discusses opportunities to create preclinical trials with improved predictive value in guiding early-phase drug development in patients with PAH, which will need support not only from researchers, peer reviewers, and editors but also from academic institutions, funding agencies, and animal ethics authorities.

AB - BACKGROUND AND PURPOSE: Cerebral microbleeds (CMBs) are radiological markers which predict future intracerebral haemorrhage. Researchers are exploring how CMBs can guide anticoagulation decisions in atrial fibrillation (AF). The purpose of this study is to evaluate the correlation of non-vitamin K antagonist oral anticoagulants (NOAC) exposure and prevalence of CMBs in Chinese patients with AF. METHODS: We prospectively recruited Chinese patients with AF on NOAC therapy of >=30 days for 3T MRI brain for evaluation of CMBs and white matter hyperintensities. Patients with AF without prior exposure to oral anticoagulation were recruited as control group. RESULTS: A total of 282 patients were recruited, including 124 patients in NOAC group and 158 patients in control group. Mean duration of NOAC exposure was 723.8+/-500.3 days. CMBs were observed in 103 (36.5%) patients. No significant correlation was observed between duration of NOAC exposure and quantity of CMBs. After adjusting for confounding factors (ie, age, hypertension, labile hypertension, stroke history and white matter scores), previous intracerebral haemorrhage was predictive of CMBs (OR 15.28, 95% CI 1.81 to 129.16), particularly lobar CMBs (OR 5.37, 95% CI 1.27 to 22.6). While white matter score was predictive of mixed lobar CMBs (OR 1.65, 95% CI 1.1 to 2.5), both exposure and duration of NOAC use were not predictive of presence of CMBs. CONCLUSIONS: In Chinese patients with AF, duration of NOAC exposure did not correlate with prevalence and burden of CMBs. Further studies with follow-up MRI are needed to determine if long-term NOAC therapy can lead to development of new CMBs.

PMID- 29599286 TI - Homologous recombination and the repair of DNA double-strand breaks. AB - Homologous recombination enables the cell to access and copy intact DNA sequence information in trans, particularly to repair DNA damage affecting both strands of the double helix. Here, we discuss the DNA transactions and enzymatic activities required for this elegantly orchestrated process in the context of the repair of DNA double-strand breaks in somatic cells. This includes homology search, DNA strand invasion, repair DNA synthesis, and restoration of intact chromosomes. Aspects of DNA topology affecting individual steps are highlighted. Overall, recombination is a dynamic pathway with multiple metastable and reversible intermediates designed to achieve DNA repair with high fidelity. PMID- 29599287 TI - The partial dissociation of MHC class I-bound peptides exposes their N terminus to trimming by endoplasmic reticulum aminopeptidase 1. AB - Endoplasmic reticulum aminopeptidase 1 (ERAP1) and ERAP2 process N-terminally extended antigenic precursors for optimal loading onto major histocompatibility complex class I (MHC I) molecules. We and others have demonstrated that ERAP1 processes peptides bound to MHC I, but the underlying mechanism is unknown. To this end, we utilized single-chain trimers (SCT) of the ovalbumin-derived epitope SIINFEKL (SL8) tethered to the H2-Kb MHC I determinant from mouse and introduced three substitutions, E63A, K66A, and W167A, at the A-pocket of the peptide binding groove in the MHC I heavy chain, which interact with the N termini of peptides. These variants significantly decreased SL8-presenting SCT at the cell surface in the presence of ERAP1, but did not affect overall SCT expression, indicating that ERAP1 trims the SL8 N terminus. Comparison of the X-ray crystal structures of WT and three variant SCTs revealed only minor perturbations of the peptide-binding domain in the variants. However, molecular dynamics simulations suggested that SL8 can dissociate partially within a sub-microsecond timescale, exposing its N terminus to the solvent. We also found that the C terminus of MHC I-bound SL8 remains deeply buried in the F-pocket of MHC I. Furthermore, free energy calculations revealed that the three SCT variants exhibit lower free energy barriers of N terminus dissociation than the WT Kb Taken together, our results are consistent with a previously observed model in which the partial dissociation of bound peptides from MHC I exposes their N terminus to trimming by ERAP1, whereas their C terminus is anchored at the F-pocket. PMID- 29599288 TI - Distinct domains in the matricellular protein Lonely heart are crucial for cardiac extracellular matrix formation and heart function in Drosophila. AB - The biomechanical properties of extracellular matrices (ECMs) are critical to many biological processes, including cell-cell communication and cell migration and function. The correct balance between stiffness and elasticity is essential to the function of numerous tissues, including blood vessels and the lymphatic system, and depends on ECM constituents (the "matrisome") and on their level of interconnection. However, despite its physiological relevance, the matrisome composition and organization remain poorly understood. Previously, we reported that the ADAMTS-like protein Lonely heart (Loh) is critical for recruiting the type IV collagen-like protein Pericardin to the cardiac ECM. Here, we utilized Drosophila as a simple and genetically amenable invertebrate model for studying Loh-mediated recruitment of tissue-specific ECM components such as Pericardin to the ECM. We focused on the functional relevance of distinct Loh domains to protein localization and Pericardin recruitment. Analysis of Loh deletion constructs revealed that one thrombospondin type 1 repeat (TSR1-1), which has an embedded WXXW motif, is critical for anchoring Loh to the ECM. Two other thrombospondin repeats, TSR1-2 and TSR1-4, the latter containing a CXXTCXXG motif, appeared to be dispensable for tethering Loh to the ECM but were crucial for proper interaction with and recruitment of Pericardin. Moreover, our results also suggested that Pericardin in the cardiac ECM primarily ensures the structural integrity of the heart, rather than increasing tissue flexibility. In conclusion, our work provides new insights into the roles of thrombospondin type 1 repeats and advances our understanding of cardiac ECM assembly and function. PMID- 29599289 TI - Interaction between the AAA ATPase p97/VCP and a concealed UBX domain in the copper transporter ATP7A is associated with motor neuron degeneration. AB - The copper-transporting ATPase ATP7A contains eight transmembrane domains and is required for normal human copper homeostasis. Mutations in the ATP7A gene may lead to infantile-onset cerebral degeneration (Menkes disease); occipital horn syndrome (OHS), a related but much milder illness; or an adult-onset isolated distal motor neuropathy. The ATP7A missense mutation T994I is located in the sixth transmembrane domain of ATP7A, represents one of the variants associated with the latter phenotype, and is associated with an abnormal interaction with p97/valosin-containing protein (VCP), a hexameric AAA ATPase (ATPase associated with diverse cellular activities) with multiple biological functions. In this study, we further characterized this interaction and discovered a concealed UBX domain in the third lumenal loop of ATP7A, between its fifth and sixth transmembrane domains. We show that the T994I substitution results in conformational exposure of the UBX domain, which then binds the N-terminal domain of p97/VCP. We also show that this abnormal interaction occurs at or near the cell plasma membrane. The UBX domain has a conserved hydrophobic FP (Phe-Pro) motif, and substitution with di-alanine abrogated the interaction and restored the proper intracellular localization of ATP7A in the trans-Golgi network. Using protein MS, we identified potential coordinating components of the ATP7AT994I-p97 complex, including NSFL1 cofactor (NSF1C or p47) that may be relevant to the pathophysiology and clinical effects associated with ATP7AT994I Our study represents the first report of p97/VCP binding to a UBX domain that is not normally exposed, resulting in an aberrant protein-protein interaction leading to motor neuron degeneration. PMID- 29599290 TI - TGFbeta and IGF1R signaling activates protein kinase A through differential regulation of ezrin phosphorylation in colon cancer cells. AB - Aberrant cell survival plays a critical role in cancer progression and metastasis. We have previously shown that ezrin, a cAMP-dependent protein kinase A-anchoring protein (AKAP), is up-regulated in colorectal cancer (CRC) liver metastasis. Phosphorylation of ezrin at Thr-567 activates ezrin and plays an important role in CRC cell survival associated with XIAP and survivin up regulation. In this study, we demonstrate that in FET and GEO colon cancer cells, knockdown of ezrin expression or inhibition of ezrin phosphorylation at Thr-567 increases apoptosis through protein kinase A (PKA) activation in a cAMP independent manner. Transforming growth factor (TGF) beta signaling inhibits ezrin phosphorylation in a Smad3-dependent and Smad2-independent manner and regulates pro-apoptotic function through ezrin-mediated PKA activation. On the other hand, ezrin phosphorylation at Thr-567 by insulin-like growth factor 1 receptor (IGF1R) signaling leads to cAMP-dependent PKA activation and enhances cell survival. Further studies indicate that phosphorylated ezrin forms a complex with PKA RII, and dephosphorylated ezrin dissociates from the complex and facilitates the association of PKA RII with AKAP149, both of which activate PKA yet lead to either cell survival or apoptosis. Thus, our studies reveal a novel mechanism of differential PKA activation mediated by TGFbeta and IGF1R signaling through regulation of ezrin phosphorylation in CRC, resulting in different cell fates. This is of significance because TGFbeta and IGF1R signaling pathways are well-characterized tumor suppressor and oncogenic pathways, respectively, with important roles in CRC tumorigenesis and metastasis. Our studies indicate that they cross-talk and antagonize each other's function through regulation of ezrin activation. Therefore, ezrin may be a potential therapeutic target in CRC. PMID- 29599291 TI - TREM2-activating antibodies abrogate the negative pleiotropic effects of the Alzheimer's disease variant Trem2R47H on murine myeloid cell function. AB - Triggering receptor expressed on myeloid cells 2 (TREM2) is an orphan immune receptor expressed on cells of myeloid lineage such as macrophages and microglia. The rare variant R47H TREM2 is associated with an increased risk for Alzheimer's disease, supporting the hypothesis that TREM2 loss of function may exacerbate disease progression. However, a complete knockout of the TREM2 gene in different genetic models of neurodegenerative diseases has been reported to result in both protective and deleterious effects on disease-related end points and myeloid cell function. Here, we describe a Trem2R47H transgenic mouse model and report that even in the absence of additional genetic perturbations, this variant clearly confers a loss of function on myeloid cells. The Trem2R47H variant-containing myeloid cells exhibited subtle defects in survival and migration and displayed an unexpected dysregulation of cytokine responses in a lipopolysaccharide challenge environment. These subtle phenotypic defects with a gradation in severity across genotypes were confirmed in whole-genome RNA-Seq analyses of WT, Trem2-/-, and Trem2R47H myeloid cells under challenge conditions. Of note, TREM2-activating antibodies that boost proximal signaling abrogated survival defects conferred by the variant and also modulated migration and cytokine responses in an antibody-, ligand-, and challenge-dependent manner. In some instances, these antibodies also boosted WT myeloid cell function. Our studies provide a first glimpse into the boost in myeloid cell function that can be achieved by pharmacological modulation of TREM2 activity that can potentially be ameliorative in neurodegenerative diseases such as Alzheimer's disease. PMID- 29599292 TI - Mitochondrial oxidative stress causes insulin resistance without disrupting oxidative phosphorylation. AB - Mitochondrial oxidative stress, mitochondrial dysfunction, or both have been implicated in insulin resistance. However, disentangling the individual roles of these processes in insulin resistance has been difficult because they often occur in tandem, and tools that selectively increase oxidant production without impairing mitochondrial respiration have been lacking. Using the dimer/monomer status of peroxiredoxin isoforms as an indicator of compartmental hydrogen peroxide burden, we provide evidence that oxidative stress is localized to mitochondria in insulin-resistant 3T3-L1 adipocytes and adipose tissue from mice. To dissociate oxidative stress from impaired oxidative phosphorylation and study whether mitochondrial oxidative stress per se can cause insulin resistance, we used mitochondria-targeted paraquat (MitoPQ) to generate superoxide within mitochondria without directly disrupting the respiratory chain. At <=10 MUm, MitoPQ specifically increased mitochondrial superoxide and hydrogen peroxide without altering mitochondrial respiration in intact cells. Under these conditions, MitoPQ impaired insulin-stimulated glucose uptake and glucose transporter 4 (GLUT4) translocation to the plasma membrane in both adipocytes and myotubes. MitoPQ recapitulated many features of insulin resistance found in other experimental models, including increased oxidants in mitochondria but not cytosol; a more profound effect on glucose transport than on other insulin regulated processes, such as protein synthesis and lipolysis; an absence of overt defects in insulin signaling; and defective insulin- but not AMP-activated protein kinase (AMPK)-regulated GLUT4 translocation. We conclude that elevated mitochondrial oxidants rapidly impair insulin-regulated GLUT4 translocation and significantly contribute to insulin resistance and that MitoPQ is an ideal tool for studying the link between mitochondrial oxidative stress and regulated GLUT4 trafficking. PMID- 29599293 TI - TagF-mediated repression of bacterial type VI secretion systems involves a direct interaction with the cytoplasmic protein Fha. AB - The bacterial type VI secretion system (T6SS) delivers effectors into eukaryotic host cells or toxins into bacterial competitor for survival and fitness. The T6SS is positively regulated by the threonine phosphorylation pathway (TPP) and negatively by the T6SS-accessory protein TagF. Here, we studied the mechanisms underlying TagF-mediated T6SS repression in two distinct bacterial pathogens, Agrobacterium tumefaciens and Pseudomonas aeruginosa. We found that in A. tumefaciens, T6SS toxin secretion and T6SS-dependent antibacterial activity are suppressed by a two-domain chimeric protein consisting of TagF and PppA, a putative phosphatase. Remarkably, this TagF domain is sufficient to post translationally repress the T6SS, and this inhibition is independent of TPP. This repression requires interaction with a cytoplasmic protein, Fha, critical for activating T6SS assembly. In P. aeruginosa, PppA and TagF are two distinct proteins that repress T6SS in TPP-dependent and -independent pathways, respectively. P. aeruginosa TagF interacts with Fha1, suggesting that formation of this complex represents a conserved TagF-mediated regulatory mechanism. Using TagF variants with substitutions of conserved amino acid residues at predicted protein-protein interaction interfaces, we uncovered evidence that the TagF-Fha interaction is critical for TagF-mediated T6SS repression in both bacteria. TagF inhibits T6SS without affecting T6SS protein abundance in A. tumefaciens, but TagF overexpression reduces the protein levels of all analyzed T6SS components in P. aeruginosa Our results indicate that TagF interacts with Fha, which in turn could impact different stages of T6SS assembly in different bacteria, possibly reflecting an evolutionary divergence in T6SS control. PMID- 29599295 TI - Diabetes Distress and Glycemic Control: The Buffering Effect of Autonomy Support From Important Family Members and Friends. AB - OBJECTIVE: To examine whether autonomy support (defined as social support for an individual's personal agency) for diabetes management from informal health supporters (family/friends) reduces the detrimental effects of diabetes distress on glycemic control. RESEARCH DESIGN AND METHODS: Three hundred eight veterans with type 2 diabetes and one or more risk factors for diabetes complications completed a survey that included measures of diabetes distress and perceived autonomy support from their main informal health supporter. Hemoglobin A1c (HbA1c) data from 12 months before and after the survey were extracted from electronic medical records. Linear mixed modeling examined the main effects and interaction of autonomy support and diabetes distress on repeated measures of HbA1c over the 12 months after the survey, controlling for mean prior 12-month HbA1c, time, insulin use, age, and race/ethnicity. RESULTS: Diabetes distress (B = 0.12 [SE 0.05]; P = 0.023) was associated with higher and autonomy support (B = -0.16 [SE 0.07]; P = 0.032) with lower subsequent HbA1c levels. Autonomy support moderated the relationship between diabetes distress and HbA1c (B = -0.13 [SE 0.06]; P = 0.027). Greater diabetes distress was associated with higher HbA1c at low (B = 0.21 [SE 07]; P = 0.002) but not high (B = 0.01 [SE 0.07]; P = 0.890) levels of autonomy support. CONCLUSIONS: Autonomy support from main health supporters may contribute to better glycemic control by ameliorating the effects of diabetes distress. Interventions that reduce diabetes distress and enhance the autonomy supportiveness of informal supporters may be effective approaches to improving glycemic control. PMID- 29599294 TI - Munc18-2, but not Munc18-1 or Munc18-3, controls compound and single-vesicle regulated exocytosis in mast cells. AB - Mast cells (MCs) play pivotal roles in many inflammatory conditions including infections, anaphylaxis, and asthma. MCs store immunoregulatory compounds in their large cytoplasmic granules and, upon stimulation, secrete them via regulated exocytosis. Exocytosis in many cells requires the participation of Munc18 proteins (also known as syntaxin-binding proteins), and we found that mature MCs express all three mammalian isoforms: Munc18-1, -2, and -3. To study their functions in MC effector responses and test the role of MC degranulation in anaphylaxis, we used conditional knockout (cKO) mice in which each Munc18 protein was deleted exclusively in MCs. Using recordings of plasma membrane capacitance for high-resolution analysis of exocytosis in individual MCs, we observed an almost complete absence of exocytosis in Munc18-2-deficient MCs but intact exocytosis in MCs lacking Munc18-1 or Munc18-3. Stereological analysis of EM images of stimulated MCs revealed that the deletion of Munc18-2 also abolishes the homotypic membrane fusion required for compound exocytosis. We confirmed the severe defect in regulated exocytosis in the absence of Munc18-2 by measuring the secretion of mediators stored in MC granules. Munc18-2 cKO mice had normal morphology, development, and distribution of their MCs, indicating that Munc18-2 is not essential for the migration, retention, and maturation of MC-committed progenitors. Despite that, we found that Munc18-2 cKO mice were significantly protected from anaphylaxis. In conclusion, MC-regulated exocytosis is required for the anaphylactic response, and Munc18-2 is the sole Munc18 isoform that mediates membrane fusion during MC degranulation. PMID- 29599297 TI - Immediate effects of an artificial change in hoof angulation on the dorsal metacarpophalangeal joint angle and cross-sectional areas of both flexor tendons. AB - Corrective shoeing is used to change hoof angulation with the intention to influence the angulation of the digital joints to reduce strain on associated tendons. The objective of this study is to examine how gradual changes in hoof angulation affect the dorsal metacarpophalangeal joint (DMPJ) angulation and cross-sectional areas (CSAs) of the deep digital flexor tendon (DDFT) and superficial digital flexor tendon (SDFT) concerning the individual toe conformation. Forelimbs of 30 horses were examined barefoot and equipped with 5 degrees , 10 degrees and 20 degrees toe wedges (TWs) and heel wedges (HWs). Phalangeal angulation and lengths were measured in lateromedial radiographs of the digit. CSAs of both flexor tendons was calculated in sonographic images. Significant effects on the DMPJ and CSA of the DDFT/SDFT were measured with 10 degrees and 20 degrees HWs or 20 degrees TWs. Both flexor tendons showed increasing CSA after heel elevation. Significant interindividual variations occurred. Phalangeal angulation and length influenced the responsivity of the parameters to a changed hoof angulation. Significant impact of corrective shoeing on the DMPJ and flexor tendons is related to a distinct change in hoof orientation and varies with individual toe conformation. Similar response of the DDFT and SDFT to raised and lowered hoof orientation needs further investigation for a more specific application of therapeutic shoeing. PMID- 29599296 TI - Relationship Between Metabolic Syndrome, Alanine Aminotransferase Levels, and Liver Disease Severity in a Multiethnic North American Cohort With Chronic Hepatitis B. AB - OBJECTIVE: Metabolic syndrome (MS) is prevalent and is associated with adverse outcomes of liver disease. We evaluated the prevalence of MS and its influence on alanine aminotransferase (ALT) levels and fibrosis, as estimated by the aspartate aminotransferase-to-platelet ratio index (APRI), in a large, multiethnic North American cohort with chronic hepatitis B (HBV) infection. RESEARCH DESIGN AND METHODS: Adults with chronic HBV from 21 centers within the U.S. and Canada were evaluated at baseline and for up to 5 years (median 3.7 years) of follow-up. MS was defined as the presence of at least three of five criteria including waist circumference, blood pressure, glucose, triglyceride, and HDL levels. RESULTS: Analysis included 777 participants, of whom 171 (22%) had MS. Participants with MS (vs. those without MS) were older (median age 54.4 vs. 40.2 years), more often male (61% vs. 51%), and born in the U.S./Canada or had immigrated >20 years ago (60% vs. 43%). MS was not associated with ALT or APRI at baseline. Upon adjusted multivariable analysis of serial ALT values, ALT was significantly higher (mean 12%; P = 0.02) among those with MS at baseline and even higher (mean 19%; P = 0.003) among those with persistent MS compared with those with persistent absence of MS. MS was not associated with serial APRI on follow-up. CONCLUSIONS: MS was prevalent in this HBV cohort and was independently associated with higher ALT levels longitudinally. These findings highlight the importance of screening for MS and the potential for MS to influence ALT and its interpretation in the context of HBV treatment decisions. PMID- 29599298 TI - Autogenous vaccination reduces antimicrobial usage and mortality rates in a herd facing severe exudative epidermitis outbreaks in weaned pigs. AB - This study was conducted in a commercial 1000-sow herd facing recurrent exudative epidermitis (EE) outbreaks during the nursery period and assessed the efficacy of autogenous vaccination in controlling such outbreaks. The vaccine was produced using three Staphylococcus hyicus isolates recovered from affected pigs shortly before the onset of the study. All of those isolates were positive for the exhB gene, which encodes the exfoliative toxin type B (ExhB). From four consecutive farrowing batches of sows, two batches were vaccinated (V) against S hyicus at five and two weeks before farrowing, and two sow batches remained non-vaccinated (NV). Vaccination efficacy was primarily determined by the levels of metaphylactic antimicrobial usage, and the morbidity and mortality data for the pigs of the V and NV sows. The total amount of antimicrobials used metaphylactically against EE in pigs among the V and NV farrowing batches was 39,600 and 88,550 mg, respectively. The used daily dose pig to animal daily dose pig ratio for the V and NV batches were 1.31 and 1.79, respectively (a ratio of 0.8 to 1.2 is indicative of correct dosing). The morbidity and mortality rates were V=6.50 and NV=14.36 (P=0.008), and V=2.59 and NV=5.02 (P=0.000), respectively. To conclude, autogenous vaccination of the sows with a vaccine based on exhB-positive S hyicus isolates reduced metaphylactic treatment with antimicrobials as well as the morbidity and mortality rates in weaned pigs compared with pigs from NV sow batches. PMID- 29599299 TI - Identification of Patients Expected to Benefit from Electronic Alerts for Acute Kidney Injury. AB - BACKGROUND AND OBJECTIVES: Electronic alerts for heterogenous conditions such as AKI may not provide benefit for all eligible patients and can lead to alert fatigue, suggesting that personalized alert targeting may be useful. Uplift-based alert targeting may be superior to purely prognostic-targeting of interventions because uplift models assess marginal treatment effect rather than likelihood of outcome. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This is a secondary analysis of a clinical trial of 2278 adult patients with AKI randomized to an automated, electronic alert system versus usual care. We used three uplift algorithms and one purely prognostic algorithm, trained in 70% of the data, and evaluated the effect of targeting alerts to patients with higher scores in the held-out 30% of the data. The performance of the targeting strategy was assessed as the interaction between the model prediction of likelihood to benefit from alerts and randomization status. The outcome of interest was maximum relative change in creatinine from the time of randomization to 3 days after randomization. RESULTS: The three uplift score algorithms all gave rise to a significant interaction term, suggesting that a strategy of targeting individuals with higher uplift scores would lead to a beneficial effect of AKI alerting, in contrast to the null effect seen in the overall study. The prognostic model did not successfully stratify patients with regards to benefit of the intervention. Among individuals in the high uplift group, alerting was associated with a median reduction in change in creatinine of -5.3% (P=0.03). In the low uplift group, alerting was associated with a median increase in change in creatinine of +5.3% (P=0.005). Older individuals, women, and those with a lower randomization creatinine were more likely to receive high uplift scores, suggesting that alerts may benefit those with more slowly developing AKI. CONCLUSIONS: Uplift modeling, which accounts for treatment effect, can successfully target electronic alerts for AKI to those most likely to benefit, whereas purely prognostic targeting cannot. PMID- 29599300 TI - Concentrations of Trace Elements and Clinical Outcomes in Hemodialysis Patients: A Prospective Cohort Study. AB - BACKGROUND AND OBJECTIVES: Deficiency of essential trace elements and excess of potentially toxic trace elements are common in patients on hemodialysis. Whether these abnormalities are associated with poor outcomes is unknown but worth investigating, because they are potentially treatable. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We did a prospective longitudinal study of 1278 patients on incident hemodialysis, assessing blood concentrations of 25 trace elements at baseline. We used adjusted logistic regression to evaluate the association between trace element status and four outcomes (death, cardiovascular events, systemic infection, and hospitalization). A priori hypotheses concerned (1) deficiency of zinc, selenium, and manganese and (2) excess of lead, arsenic, and mercury. Concentrations of the other 19 elements were tested in hypothesis generating analyses. RESULTS: Over 2 years of follow-up, 260 (20%) patients died, 285 (24%) experienced a cardiovascular event, 117 (10%) were hospitalized for systemic infection, and 928 (77%) were hospitalized for any cause. Lower concentrations of zinc or manganese and higher concentrations of lead, arsenic, or mercury were not independently associated with higher risk of clinical outcomes. Lower concentrations of selenium were strongly and independently associated with death (odds ratio, 0.86 per decile; 99.2% confidence interval, 0.80 to 0.93) and all-cause hospitalization (odds ratio, 0.92 per decile; 99.2% confidence interval, 0.86 to 0.98). In exploratory analyses, higher copper concentrations were significantly associated with higher risk of death (odds ratio, 1.07 per decile; 99.2% confidence interval, 1.00 to 1.15), and cadmium levels in the highest decile were associated with higher risk of death (odds ratio, 1.89; 99.2% confidence interval, 1.06 to 3.38). CONCLUSIONS: Lower levels of zinc or manganese and higher concentrations of lead, arsenic, or mercury were not associated with higher risk of clinical outcomes, but lower concentrations of selenium were strongly and independently associated with the risks of death and hospitalization. PMID- 29599301 TI - Visualizing the Tumor Microenvironment by Color-coded Imaging in Orthotopic Mouse Models of Cancer. AB - The tumor microenvironment (TME) contains stromal cells in a complex interaction with cancer cells. This relationship has become better understood with the use of fluorescent proteins for in vivo imaging, originally developed by our laboratories. Spectrally-distinct fluorescent proteins can used for color-coded imaging of the complex interaction of the tumor microenvironment in the living state using cancer cells expressing a fluorescent protein of one color and host mice expressing another-color fluorescent protein. Cancer cells engineered in vitro to express a fluorescent protein were orthotopically implanted into transgenic mice expressing a fluorescent protein of a different color. Confocal microscopy was then used for color-coded imaging of the TME. Color-coded imaging of the TME has enabled us to discover that stromal cells are necessary for metastasis. Patient-derived orthotopic xenograft (PDOX) tumors were labeled by first passaging them orthotopically through transgenic nude mice expressing either green, red, or cyan fluorescent protein in order to label the stromal cells of the tumor. The colored stromal cells become stably associated with the PDOX tumors through multiple passages in transgenic colored mice or non-colored mice. The fluorescent protein-expressing stromal cells included cancer-associated fibroblasts and tumor-associated macrophages. The cancer cells in PDOX models can also be labeled with a telomerase-dependent adenovirus containing the gene for green fluorescent protein. Using this model, specific cancer-cell or stromal-cell targeting by potential therapeutics can be visualized. Color-coded imaging enabled the visualization of apparent fusion of cancer and stromal cells. Color coded imaging is a powerful tool visualizing the interaction of cancer and stromal cells during cancer progression and treatment. PMID- 29599302 TI - Molecular Sequence of Events and Signaling Pathways in Cerebral Metastases. AB - Brain metastases are the leading cause of morbidity and mortality among cancer patients, and are reported to occur in about 40% of cancer patients with metastatic disease in the United States of America. Primary tumor cells appear to detach from the parent tumor site, migrate, survive and pass through the blood brain barrier in order to establish cerebral metastases. This complex process involves distinct molecular and genetic mechanisms that mediate metastasis from these primary organs to the brain. Furthermore, an interaction between the invading cells and cerebral milieu is shown to promote this process as well. Here, we review the mechanisms by which primary cancer cells metastasize to the brain via a mechanism called epithelial-to-mesenchymal transition, as well as the involvement of certain microRNA and genetic aberrations implicated in cerebral metastases from the lung, breast, skin, kidney and colon. While the mechanisms governing the development of brain metastases remain a major hindrance in treatment, understanding and identification of the aforementioned molecular pathways may allow for improved management and discovery of novel therapeutic targets. PMID- 29599303 TI - Radiotherapy May Offer a Recurrence and Survival Benefit in Rectal Cancers Treated Surgically with Transanal Endoscopic Microsurgery: A Systematic Review and Meta-analysis. AB - BACKGROUND/AIM: Several studies report outcomes of Transanal Endoscopic Microsurgery (TEMS) surgery in combination with radiotherapy, however the combination of those treatments is provided mostly on an adhoc individual basis and the role of radiotherapy remains unclear. The aim of this study was to identify the effect of neo-adjuvant or adjuvant radiotherapy in the oncological outcomes of rectal cancer treated surgically with TEMS. MATERIALS AND METHODS: We performed a systematic review of the literature on MEDLINE and Pubmed databases. Data were extracted by two independent reviewers and meta-analyzed using an inverse variance heterogeneity model to calculate overall (pooled) effect sizes for survival or recurrence of disease against neo+/-adjuvant treatment. RESULTS: A total of 48 studies were included in the qualitative meta-analysis which included 3,285 patients with rectal cancer. The overall survival odds ratio (OR), was 9.39 (95% CI=6.1-14.4) with a Cochran's Q variable of 151.7 on 47 degrees of freedom (d.f.) (p=0.000). Recurrence-free OR was 8.7 (95%CI=6.58-11.44) with a Cochran's Q variable of Q=145.2 on 44 d.f. (p=0.000). Studies which contained more than 10% of pT3 tumours, and provided neo+/-adjuvant treatment in more than 35% of cases, were associated with survival benefit, as demonstrated by an overall odds of survival of 32.2 (95%CI=16.3-63.5, p=0.001, Q=8.4, p=0.21). Studies that contained more than 10% of pT3 tumours and provided neo+/-adjuvant treatment in more than 20% of the cases had an overall effect size of recurrence free odds of 20.23 (95%CI=13.84-29.57, p=0.000, Q=2.18, p=0.54). CONCLUSION: There seems to be a benefit from radiotherapy on overall survival and recurrence free odds, which is more apparent in cohorts with more than 10% of pT3 tumours. Our results suggest that neo-adjuvant or adjuvant radiotherapy should be considered for inclusion in formal treatment protocols for rectal cancers treated with TEMS as they offer a recurrence and survival benefit. PMID- 29599304 TI - Aspirin in the Management of Patients with Prostate Cancer Undergoing Radiotherapy: Friend or Foe? AB - Aspirin has cyclooxygenase-2 (COX2)-mediated anti-inflammatory and anti-coagulant properties that may confer a positive effect in preventing and limiting the progression of prostate cancer. Prostate cancer has been shown to have poor treatment outcomes due to therapeutic resistance; therefore, COX2 inhibition caused by aspirin could represent an opportunity to augment current therapies. This is particularly of interest to patients undergoing radiation therapy (RT) where inflammation is a common side-effect. This review discusses the evidence for the potential role of aspirin in the management of patients with prostate cancer undergoing RT. PMID- 29599305 TI - Clinicopathological and Molecular Factors, Risk Factors, Treatment Outcomes and Risk of Recurrence in Mesenteric and Retroperitoneal Extragastrointestinal Stromal Tumors. AB - BACKGROUND/AIM: The objective of the present study was to determine the clinicopathological factors and treatment outcomes of patients suffering from mesenteric or retroperitoneal extragastrointestinal stromal tumors (EGISTs). MATERIALS AND METHODS: A detailed search in PubMed, using the key words "extragastrointestinal stromal tumors" and "EGIST", found eight studies fulfilling the criteria of this study. RESULTS: Thirty-six patients with a mesenteric and 24 patients with a retroperitoneal EGIST were analyzed, with a follow-up period ranging from 2 to 192 months. Retroperitoneal tumors presented as larger tumors than mesenteric ones, with 95% and 93% immunohistochemical positivity for CD117 antigen, respectively. Surgical resection was performed in 91% of cases, with 57% of patients with mesenteric and 70% of patients with retroperitoneal EGISTs being alive at the last follow-up. CONCLUSION: EGISTs most commonly are of considerable size and usually with a high mitotic count, rendering them high-risk tumors. Tumor necrosis, nuclear atypia, tumor histology, and mutations in the tyrosine kinase KIT or platelet-derived growth factor receptor A (PDGFRA) gene, seem to influence tumor behavior. PMID- 29599306 TI - Laparoscopic Intragastric Surgery for Treating Early Gastric Cancer. AB - BACKGROUND/AIM: Although there is an increasing number of studies on laparoscopic resection of early gastric cancer (EGC), as of 2018 no standardized strategy exists. We reviewed available literature dealing with laparoscopic intragastric (intraluminal) surgery (LIGS) conducted for patients with EGC to better define indications, benefits and limitations of this particular minimally invasive technique. MATERIALS AND METHODS: PubMed, MEDLINE, Science Direct, Scopus, Web of Science, Google Scholar and ResearchGate were the search engines investigated. Only LIGS for EGC was entertained; studies conducted for other gastric diseases were excluded. Suitable articles written in all languages were included in the review. RESULTS: As of 2018, we found 19 studies dealing with LIGS for EGC: studies on 72 humans and four pigs were identified. Among 72 human participants, there were 59 mucosal, five submucosal and one subserosal cancer. CONCLUSION: Based on our review, LIGS appears as a cogent option to endoscopic resection for treating superficial EGC. PMID- 29599307 TI - Ethanolic Extract of Traditional Chinese Medicine (TCM) Gamboge Inhibits Colon Cancer via the Wnt/Beta-Catenin Signaling Pathway in an Orthotopic Mouse Model. AB - BACKGROUND/AIM: The aim of the present study was to investigate the efficacy of an ethanolic extract of gamboge (EEG), a traditional Chinese medicine (TCM), both in vitro on colon cancer cells and in vivo in an orthotopic mouse model of human colon cancer. MATERIALS AND METHODS: The in vitro cytotoxicity of EEG on colon cancer cells was determined with the CCK8 proliferation assay and the Annexin V PE/7-AAD apoptosis assay. Efficacy of EEG in vivo was evaluated in an orthotopic mouse model of human colon cancer implated with the green fluorescent protein expressing human colon cancer cell line SW480-GFP. The tumor-bearing mice were treated with vehicle (0.2 ml/dose normal saline, po, daily), irinotecan (50 mg/kg/dose, ip, twice a week), 5-FU (15 mg/kg/dose, ip, every other day) as positive controls or EEG at doses of 12.5, 25 and 50 mg/kg/dose, po, daily. Real time fluorescence imaging was performed to determine tumor inhibition in each treated group compared to the untreated controls. The protein expression of beta catenin, MMP-7, cyclin D1 and E-cadherin in the tumors was analyzed by immunohistochemistry. RESULTS: EEG significantly induced proliferation inhibition and apoptosis of SW480 colon cancer cells in vitro in a dose-dependent manner. Tumor growth in the colon-cancer orthotopic model was significantly inhibited by irinotecan, 5-FU and all three doses of EEG. The efficacy of EEG was comparable to irinotecan and 5-FU. Irinotecan, 5-FU and 50 mg/kg EEG significantly decreased the protein expression of beta-catenin and MMP-7. Cyclin D1 expression was decreased and E-cadherin expression was increased by irinotecan, 5-FU and all three doses of EEG. CONCLUSION: The present study demonstrates anti-tumor efficacy of EEG on colon cancer both in vitro and in vivo through inducing proliferation inhibition and apoptosis of SW480 colon cancer cells and inhibiting tumor growth, respectively. EEG exerts anti-tumor activity at least partly via down-regulation of the Wnt/beta-catenin signaling pathway. PMID- 29599308 TI - Differential Organ-targeting and Cellular Characteristics of Metastatic Human Pancreatic Cancer Cell Lines in Mouse Models. AB - BACKGROUND/AIM: The lethal characteristic of pancreatic cancer is metastasis which is recalcitrant to currently-used chemotherapy. Our aim was to understand metastasis at the cellular level. We previously reported that multi-nucleate cells or spindle cells were more prominent in pancreatic cancer metastasis than in the primary tumor. In the present report, we investigated four representative human pancreatic cell lines for differences in cell morphology between the primary tumor and various metastatic organ targets for each cell line. MATERIALS AND METHODS: Human pancreatic cancer cell lines AsPC-1, Panc-1, KP2 and KP3 were used. Pancreatic cancer cells were injected into spleen of nude mice resulting in experimental metastasis to various organs which were observed at the cellular level when the organs were placed into culture. RESULTS: AsPC-1 and KP2 pancreatic cells formed many experimental liver metastases, in contrast to Panc-1 and KP3. Lung metastasis was only observed for AsPC-1. In the cultures established from the primary and metastatic tumors, multi-nucleate cells were found to be more prominent in the metastasis of the pancreatic cell lines with frequent metastasis, AsPC-1 and KP2. Spindle-like cells were observed prominently in AsPC-1 lung metastasis. CONCLUSION: Human pancreatic cancer cell lines have differential metastatic characteristics with regard to target organs and cell morphology changes. Multi-nucleate and spindle cells may play an important role in pancreatic cancer metastasis to the liver and lung, respectively. PMID- 29599309 TI - MEKK3 Sustains EMT and Stemness in Pancreatic Cancer by Regulating YAP and TAZ Transcriptional Activity. AB - BACKGROUND/AIM: Pancreatic cancer is one of the most threatening and poorly understood human malignancies. MEKK3 (MAP3K3) is a serine/threonine kinase activated by different signaling pathways. YAP and TAZ are critical oncogenic effectors in pancreatic cancer. We hypothesized that MEKK3 could sustain pancreatic cancer by inducing YAP/TAZ oncogenic activities. MATERIALS AND METHODS: In Panc1 and AsPC1 pancreatic cancer cell lines MEKK3 was knocked-out (KO) by the CRISPR/Cas9 method. These cells were used to evaluate MEKK3 contribution to the expression of YAP/TAZ and their target genes, cell migration, stemness, and in vivo tumor growth. RESULTS: MEKK3 KO reduced both EMT and cell migration, the size of 3D colonies and the percentage of CD44+/CD24+/EpCAM+ CSC, promoter recruitment of YAP/TAZ and the expression of their target genes. It reduced tumor growth and prolonged mice overall survival. CONCLUSION: Silencing of MEKK3 represents a valid approach to revert in vivo the aggressiveness of pancreatic cancer by modulating YAP/TAZ transcriptional activities. PMID- 29599310 TI - Antitumor Activity of Novel Bone-seeking, alpha-emitting 224Ra-solution in a Breast Cancer Skeletal Metastases Model. AB - BACKGROUND/AIM: Bone metastases are associated with increased morbidity and poor prognosis in a variety of cancers. The present study investigated the effects of targeted radionuclide therapy with alpha-emitting, bone-seeking radium-224 (224Ra) on osteolytic bone metastasis of MDA-MB-231(SA)-GFP human breast cancer cells injected intracardially into nude mice. MATERIALS AND METHODS: Vehicle, ethylenediamine tetra (methylene phosphonic acid) (EDTMP) and 224Ra-solution (45, 91 or 179 kBq/kg) with EDTMP were intravenously administered to mice two days after cell injection. The bone-seeking EDTMP was added to the 224Ra-solution to improve bone targeting of 212Pb, which is a progeny of 224Ra. RESULTS: Radium-224 solution treatment decreased in a dose-dependent manner the areas of osteolytic lesions in the hind limbs and the number of tumor foci in the whole skeleton, and extended survival. Paraplegia was not observed in 179 kBq/kg 224Ra-solution group. CONCLUSION: Radium-224-solution containing chelated 212Pb is a promising candidate for the treatment of breast cancer patients with bone metastases. PMID- 29599311 TI - Podoplanin-positive Cancer-associated Stromal Fibroblasts in Primary Tumor and Synchronous Lymph Node Metastases of HER2-overexpressing Breast Carcinomas. AB - We compared the status of stromal podoplanin-positive cancer-associated fibroblasts (ppCAFs) between primary tumors and paired synchronous lymph node metastases (LNMs) and analyzed the prognostic significance of tumoral ppCAFs in 203 patients with human epidermal growth factor receptor 2-positive breast carcinoma. ppCAFs were found in 167/203 and in 35/87 tumors and LNM, respectively. ppCAFs were most frequently found in tumors and corresponding LNM (n=52, 59.8%; p=0.001). However, for all LNMs (n=12) without ppCAFs, their paired tumors also lacked ppCAFs. In both tumors and LNMs, ppCAFs were alpha-smooth muscle actin-positive and cluster of differentiation 21 protein-negative, suggesting them not to be resident lymph node cells. Moreover, in our series, the presence of ppCAFs in tumors was borderline related to poor disease-free survival (p=0.058). These results speak in favor of a hypothesis suggesting ppCAFs accompany metastatic cancer cells migrating from tumor to LNMs. PMID- 29599312 TI - In Vitro Elucidation of Drug Combination Synergy in Treatment of Pancreatic Ductal Adenocarcinoma. AB - BACKGROUND/AIM: Advances in therapies targeting proteins and pathways affected by genetic alterations has raised the possibility of personalized cancer treatments. MATERIALS AND METHODS: The efficacy of targeting molecular aberrations was determined in the pancreatic ductal adenocarcinoma (PDAC) cell line, CAPAN2. Two mutations were targeted, KRAS (p.G12V) and ABL1 (p.G1060D), and cells were treated with regorafenib and trametinib, individually and in combination. RESULTS: Exposure to either drug significantly increased cell death compared to the current standard of care, gemcitabine. Treatment with combinations of the drugs led to significant increases in cell death compared to either monotherapy. Strong additive/synergistic interactions were observed across a range of dosages and ratios, reducing dose requirements with potential clinical relevance. CONCLUSION: The data obtained in this PDAC cell model: i) support the use of matched monotherapies; ii) indicate the effectiveness of matched combination therapies; and iii) provide potential proof-of-concept for precision medicine approach to cancer treatment. PMID- 29599313 TI - The Novel Selective Pan-TRK Inhibitor ONO-7579 Exhibits Antitumor Efficacy Against Human Gallbladder Cancer In Vitro. AB - We previously reported that brain-derived neurotrophic factor (BDNF)/neurotrophic receptor tyrosine kinase 2 (NTRK2/TRKB) signaling contributes to induction of malignant phenotype of gallbladder cancer (GBC). Recently, pan-TRK inhibitors have been evaluated and their dramatic clinical activity is being shown for a variety of cancer types harboring an NTRK rearrangement in phase I trials. ONO 7579 is an oral pan-TRK inhibitor currently under investigation in phase I/II clinical trial for TRK-rearranged solid tumors. In this study, we evaluated the anticancer effect of ONO-7579 using GBC cells with or without KRAS mutant, NOZ, TYGBK-1. Our study showed that ONO-7579 had a suppressive effect on GBC proliferation in TYGBK-1, and on invasive potential and vascular endothelial growth factor expression in TYGBK-1 and NOZ. Our data indicated that ONO-7579 could be a promising treatment option for patients with GBC. PMID- 29599314 TI - Correlation of Expression of Tenascin C and Blood Vessel Density in Non-small Cell Lung Cancers. AB - BACKGROUND/AIM: Non-small cell lung cancers are cancer diseases that rank second in terms of incidence and first in terms of mortality, worldwide. Stromal cells of these cancers express tenascin C (TNC) - hexameric glycoprotein, which is also expressed during foetal life. TNC is also observed in stromal cells of most human cancers. In some cancers, TNC was shown to influence proliferation and migration of cancer cells and angiogenesis. The aim of this work was to analyze the correlation of expression of TNC with the markers of vascular endothelial cells, CD31 and CD34, and clinicopathological data in NSCLC. MATERIALS AND METHODS: Archival paraffin blocks from 101 cases of NSCLC were used for the studies. Immunohistochemical reactions were carried out on paraffin sections using mouse monoclonal antibodies anti-TNC, anti-CD31 and anti-CD34, with the use of Autosteiner Link-48. RESULTS: Statistical analysis of the results showed positive correlation between TNC expression and CD31(+) and CD34(+) microvessel density (MVD) (r=0.456, p<0.0001; r=0.296, p<0.01, respectively). CONCLUSION: Based on the obtained results it can be concluded, that TNC may be involved in angiogenesis in NSCLC. PMID- 29599316 TI - The Role of MTHFR Genotype in Colorectal Cancer Susceptibility in Taiwan. AB - AIM: To evaluate the contribution of methylenetetrahydrofolate reductase (MTHFR) genotype to the risk of colorectal cancer (CRC) in Taiwan. MATERIALS AND METHODS: In this hospital-based case-control study, the role of MTHFR C677T (rs1801133) and A1298C (rs1801131) genotypes in determining CRC risk were investigated among 362 patients with CRC and an equal number of age- and gender-matched healthy individuals. RESULTS: The percentages of CC, CT and TT genotypes for MTHFR rs1801133 were 64.1%, 29.8% and 6.1% in the CRC group and 51.1%, 37.0% and 11.9% in the control group, respectively (p for trend=0.0006). Analysis of the allelic frequency distribution showed that the variant T allele of MTHFR rs1801133 conferred a lower CRC susceptibility than did the wild-type C allele (odds ratio(OR)=0.66, 95% confidence interval(CI)=0.52-0.84, p=4.32*10-5). For the gene lifestyle interaction, there were obvious protective effects of MTHFR rs1801133 T allele on the risk of CRC among non-smokers, ever smokers and non-alcohol drinkers, but not drinkers. CONCLUSION: MTHFR rs1801133 T allele serves as a predictive marker for CRC risk and future studies with larger samples and functional evaluation are warranted to validate the current findings. PMID- 29599315 TI - Melatonin Promotes Apoptosis of Oxaliplatin-resistant Colorectal Cancer Cells Through Inhibition of Cellular Prion Protein. AB - BACKGROUND/AIM: Drug resistance restricts the efficacy of chemotherapy in colorectal cancer. However, the detailed molecular mechanism of drug resistance in colorectal cancer cells remains unclear. MATERIALS AND METHODS: The level of cellular prion protein (PrPC) in oxaliplatin-resistant colorectal cancer (SNU C5/Oxal-R) cells was assessed. RESULTS: PrPC level in SNU-C5/Oxal-R cells was significantly increased compared to that in wild-type (SNU-C5) cells. Superoxide dismutase and catalase activities were higher in SNU-C5/Oxal-R cells than in SNU C5 cells. Treatment of SNU-C5/Oxal-R cells with oxaliplatin and melatonin reduced PrPC expression, while suppressing antioxidant enzyme activity and increasing superoxide anion generation. In SNU-C5/Oxal-R cells, endoplasmic reticulum stress and apoptosis were significantly increased following co-treatment with oxaliplatin and melatonin compared to treatment with oxaliplatin alone. CONCLUSION: Co-treatment with oxaliplatin and melatonin increased endoplasmic reticulum stress in and apoptosis of SNU-C5/Oxal-R cells through inhibition of PrPC, suggesting that PrPC could be a key molecule in oxaliplatin resistance of colorectal cancer cells. PMID- 29599317 TI - Transforming Growth Factor-Beta Produced by Non-small Cell Lung Cancer Cells Contributes to Lung Fibroblast Contractile Phenotype. AB - BACKGROUND/AIM: Fibroblasts can alter the extracellular matrix (ECM), contributing to cancer progression by providing a scaffold for cancer cells. The influence of lung cancer cells (LCCs) on lung fibroblast-mediated ECM alteration is not well understood. MATERIALS AND METHODS: After incubation in serum-free medium, LCC- or fibroblast-conditioned media were collected. The ECM alteration was assessed by collagen gel contraction assay. RESULTS: Both LCC-conditioned medium and exogenous transforming growth factor (TGF)-beta1 increased collagen gel contraction by lung fibroblasts. TGF-beta1 was produced in LCC-conditioned media at approximately 2 ng/ml. SB431542, a specific TGF-beta receptor kinase inhibitor, partially inhibited the collagen gel contraction that had been increased by LCC-conditioned media. Lung fibroblast-conditioned medium stimulated TGF-beta1 production from LCCs, whereas LCC-conditioned medium decreased fibroblast survival and alpha-smooth muscle actin expression by fibroblasts. CONCLUSION: Interaction between LCCs and lung fibroblasts through TGF-beta signaling induces fibroblasts to assume the contractile phenotype and may contribute to cancer progression. PMID- 29599318 TI - Lentiviral Vector-mediated Gene Transfer in Human Bladder Cancer Cell Lines. AB - BACKGROUND/AIM: Currently, treatment of non-muscle invasive bladder cancer causes significant deterioration in a patient's quality of life (QOL). Therefore, development of novel therapeutic options without the deterioration of QOL is very important. In this study, we assessed the anti-tumor effect of lentivirus mediated gene transfection of tumor-suppressor genes in human bladder cancer cells. MATERIALS AND METHODS: Lentiviral vectors that contained the tumor suppressor genes, p53, p16, and PTEN, were transfected into human bladder cancer cell lines, 5637, T24, 253J, and UMUC3, and the normal human uroepithelial cell line, SV-HUC-1. RESULTS: Significant growth inhibition was observed in bladder cancer cells on transfection with the p16 and PTEN vectors. However, the effect of the p53 vector was limited. In normal cells, the lentiviral vectors did not exhibit a significant growth inhibitory effect. CONCLUSION: Lentiviral vector mediated gene transfection is useful for the application of gene therapy in bladder cancers. PMID- 29599319 TI - Aberrant Expression of PIWIL1 and PIWIL2 and Their Clinical Significance in Ductal Breast Carcinoma. AB - BACKGROUND/AIM: P-Element-induced wimpy testis (PIWI) proteins in complex with PIWI-interacting RNA (piRNA) are involved in epigenetic regulation of gene expression in germline cells. Aberrant expression of piRNA and PIWI proteins have been identified in various types of tumour cells. The aim of this study was to evaluate the expression profiles of PIWI-like protein-1, -2 (PIWIL1 and PIWIL2), their immunohistochemical (IHC) characteristics in ductal breast cancer, and determine their correlation with clinicopathological parameters of this type of cancer. MATERIALS AND METHODS: Material for IHC studies comprised of 101 invasive ductal carcinoma (IDC) cases and 31 mastopathy tissues. Frozen fragments of paired tissue specimens (tumour and adjacent non-malignant breast tissue) taken from 55 patients with IDC and 18 samples of mastopathy were used for molecular studies using real-time polymerase chain reaction (RT-PCR). RESULTS: A statistically significantly higher level of PIWIL1 and PIWIL2 was found in IDC compared to mastopathy samples (p<=0.0001). Increased expression of PIWIL1 was correlated with increased PIWIL2 expression in breast cancer tissue. Surprisingly, PIWIL1 mRNA was detected only in cancer and mastopathy, but was not found in most normal breast tissues, although it is noteworthy that the PIWIL2 mRNA level was statistically significantly lower in mastopathy and IDC samples compared to normal breast tissues. CONCLUSION: Our results affirm the hypothesis that reactivation of PIWI expression in various caner types is crucial for cancer development. PMID- 29599320 TI - MicroRNA-96 Promotes Tumor Invasion in Colorectal Cancer via RECK. AB - BACKGROUND: miR-96 is reported to inhibit reversion cysteine-rich Kazal motif (RECK), which is associated with tumor invasion, in solid cancer types (e.g. breast cancer, non-small cell lung cancer, esophageal cancer). The purpose of this study is to clarify whether miR-96 is similarly associated with tumor invasion in colorectal cancer. MATERIALS AND METHODS: We performed western blotting to investigate the expression of RECK when miR-96 mimics or inhibitors were transferred into HCT-116 colorectal cancer cells. The RECK mRNA level was assessed by a reverse transcription polymerase chain reaction. An invasion assay was used to evaluate tumor invasion. RESULTS: The expression of RECK was inhibited by the transfection of miR-96 mimics. RECK mRNA level was reduced by miR-96 mimics and increased by miR-96 inhibitor. In the invasion assay, miR-96 mimics were shown to promote tumor invasion. CONCLUSION: miR-96 may be associated with tumor invasion through inhibition of RECK expression in colorectal cancer. PMID- 29599321 TI - Induction of Mitotic Catastrophe in Human Cervical Cancer Cells After Administration of Aloe-emodin. AB - BACKGROUND: Aloe-emodin is an anthraquinone with potential pharmacological properties, including numerous antitumor properties. The purpose of the study was to determine whether aloe-emodin induces mitotic death in cervical cancer cells. MATERIALS AND METHODS: Analysis of morphological changes as surrogate mitotic death indicators in HeLa cells was carried out using optical, fluorescence and electron microscopy. Viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2-5 diphenyltetrazolium bromide reduction assay. Cell-cycle analysis was performed using flow cytometry. RESULTS: Aloe-emodin increased the number of multinucleate cells, giant and micronuclear cells. There was a concentration-dependent decrease in the mitotic index with a predominance of cells in the metaphase of the mitotic process and inhibition of division in the G2/M phase of the cell cycle. The presence of cells with abnormal mitosis and cells with injury to the division spindle was also demonstrated. CONCLUSION: Aloe-emodin induces mitotic catastrophe in cervical cancer cells. PMID- 29599322 TI - Crosstalk Between Androgen-sensitive and Androgen-insensitive Prostate Cancer Cells. AB - AIM: To investigate how androgen-sensitive LNCaP cells crosstalk with androgen insensitive DU145 or PC-3 cells. MATERIALS AND METHODS: The numbers of LNCaP cells were counted when co-cultured with DU145 or PC-3 cells and vise versa. Androgen receptor (AR) activity in LNCaP cells was examined by luciferase reporter assay after transfection with a luciferase reporter driven by PSA promoter in the presence of DU145 or PC-3 cells. Concentration of androgens in the medium was measured by liquid chromatography-mass spectrometry (LC-MS/MS). The ability of migration and invasion of PC-3 and DU145 cells was investigated using a 2-layer chamber, in the presence of LNCaP cells. RESULTS: Co-culture of LNCaP cells with DU145 cells resulted in the conversion of dehydroepiandrosterone (DHEA) to dihydrotestosterone (DHT), which stimulated cell proliferation and PSA promoter activity in LNCaP cells. The increased cell proliferation rate and AR activity, induced in LNCaP cells after DHT treatment, was further enhanced by co culture with DU145 cells. LNCaP cells also stimulated the proliferation of DU145 and PC-3 cells, via secreting soluble factors. Finally, LNCaP cells promoted migration and invasion of PC-3 cells, in a co-culture system; however inhibited migration and invasion of DU145 cells. CONCLUSION: Crosstalk between androgen sensitive PCa cells and androgen-insensitive PCa cells might develop the progression of PCa. PMID- 29599323 TI - Gallic Acid Induces Apoptosis in Human Gastric Adenocarcinoma Cells. AB - BACKGROUND/AIM: Gastric cancer is one of the most common malignant cancers with a poor prognosis and high mortality rate worldwide. Current treatment of gastric cancer includes surgery and chemotherapy as the main modalities, but the potentially severe side-effects of chemotherapy present a considerable challenge. Gallic acid is a trihydroxybenzoic acid found to exert an anticancer effect against a variety of cancer cells. The purpose of this study was to determine the anti-cancer activity of Galla chinensis and its main component gallic acid on human gastric adenocarcinoma cells. MATERIALS AND METHODS: MTT assay and cell death ELISA were used to determine the apoptotic effect of Gallic Chinensis and gallic acid on human gastric adenocarcinoma cells. To determine the pathway and relevant components by which gallic acid-induced apoptosis is mediated through, cells were transfected with siRNA (Fas, FasL, DR5, p53) using Lipofectamine 2000. Reults: Gallic Chinensis and gallic acid induced apoptosis of human gastric adenocarcinoma cells. Gallic acid induced up-regulation of Fas, FasL, and DR5 expression in AGS cells. Transfection of cells with Fas, FasL, or DR5 siRNA reduced gallic acid-induced cell death. In addition, p53 was shown to be involved in gallic acid-mediated Fas, FasL, and DR5 expression as well as cell apoptosis in AGS cells. CONCLUSION: These results suggest that gallic acid has a potential role in the treatment of gastric cancer. PMID- 29599324 TI - PD-1 and PD-L1 Up-regulation Promotes T-cell Apoptosis in Gastric Adenocarcinoma. AB - BACKGROUND/AIM: The programmed death 1 (PD-1) receptor and its ligand (PD-L1) play pivotal roles in regulating host immune responses. However, the inhibitory effects of this pathway on the function of tumor infiltrating T lymphocytes in gastric adenocarcinoma patients are not well-defined. MATERIALS AND METHODS: We characterized the expression of PD-1 and PD-L1 in peripheral blood and tumor infiltrating cells and analyzed the association between PD-1/PD-L1 expression and disease progression in a cohort of 60 patients with Helicobacter pylori infection, including 18 with gastric adenocarcinoma, 23 with gastritis, and 19 asymptomatic controls. RESULTS: Relative to controls, the expression of PD-1 on peripheral blood and tumor infiltrating T cells increased with disease progression. In vitro, T cells induced PD-L1 expression on primary gastric adenocarcinoma epithelial cells in an IFN-gamma-dependent manner, which in turn promoted T cells apoptosis. Blocking of PD-L1 reversed this effect. CONCLUSION: This study provides evidence for a new therapeutic target in gastric adenocarcinoma patients. PMID- 29599325 TI - Blocking the Cleavage of Filamin A by Calpain Inhibitor Decreases Tumor Cell Growth. AB - BACKGROUND/AIM: Filamin A (FLNA) is the most abundant and widely expressed isoform of filamin in human tissues. It is cleaved by calpain at the hinge 1 and 2 domains, producing a 90-kDa carboxyl-terminal fragment (FLNACT). Recently, it has been shown that FLNACT mediates cell signaling and transports transcription factors into the cell nucleus. However, the significance of cleavage of FLNA by calpain has not been studied in cancer cell growth. Calpeptin is a chemical inhibitor of both calpain 1 and 2 that cleaves FLNA. In this study, we questioned if inhibiting calpain using calpeptin would decrease tumor cell proliferation, migration, invasion, and colony formation. MATERIALS AND METHODS: Human melanoma (A7), prostate cancer (PC3), mouse fibrosarcoma (T241) and endothelial (MS1) cells were assayed for proliferation, migration, invasion and colony formation after treatment with calpeptin. Cell lysates were immunoblotted for FLNA and FLNACT Results: Calpeptin treatment of these cells resulted in a decreased production of FLNACT Calpeptin-treated human and mouse tumor cells displayed impaired proliferation, migration, and colony formation. CONCLUSION: These data suggest that the cleavage of FLNA by calpain is an important cellular event in the regulation of tumor cell growth. PMID- 29599326 TI - Association of Matrix Metalloproteinase-7 Genotypes to the Risk of Oral Cancer in Taiwan. AB - BACKGROUND/AIM: Matrix metalloproteinases (MMPs) play a critical role in inflammation and carcinogenesis, and the expression of mRNA MMP7 in oral squamous cell carcinoma tissues was higher than in the oral lichen planus or normal oral mucosa. However, the genotypic role of MMP7 has never been examined in oral cancer. Therefore, in the current study we aimed to examine the contribution of genotypic variants in the promoter region of MMP7 (A-181G and C-153T) to oral cancer risk in Taiwan. MATERIALS AND METHODS: In this hospital-based case-control study, 788 patients with oral cancer and 956 gender-and age-matched healthy controls were genotyped for MMP7 A-181G and C-153T via polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) methodology. RESULTS: The distribution pattern of AA, AG and GG for MMP7 promoter A-181G genotype was 88.2, 10.4 and 1.4% in the oral cancer patient group and 89.0, 9.3 and 1.7% in the healthy control group, respectively (p for trend=0.6779), non-significantly differentially distributed between the two groups. There is no polymorphic genotype for MMP7 C-153T among Taiwanese. The comparisons in allelic frequency distribution also support the findings that G allele may not be the risk determinant allele for oral cancer. There is no interaction between the genotypes of MMP7 with age, gender, smoking, alcohol or betel quid consumption on oral cancer risk. CONCLUSION: Our results indicate that the MMP7 promoter genotypes only play an indirect role in determining the personal susceptibility to oral cancer in Taiwan. PMID- 29599327 TI - Detection of EGFR Gene Mutation by Mutation-oriented LAMP Method. AB - BACKGROUND/AIM: Epidermal growth factor receptor (EGFR) is a target of molecular therapeutics for non-small cell lung cancer. EGFR gene mutations at codons 746 753 promote constitutive EGFR activation and result in worst prognosis. However, these mutations augment the therapeutic effect of EGFR-tyrosine kinase inhibitor. Therefore, the detection of EGFR gene mutations is important for determining treatment planning. The aim of the study was to establish a method to detect EGFR gene mutations at codons 746-753. MATERIALS AND METHODS: EGFR gene mutation at codons 746-753 in six cancer cell lines were investigated. A loop-mediated isothermal amplification (LAMP)-based procedure was developed, that employed peptide nucleic acid to suppress amplification of the wild-type allele. RESULTS: This mutation-oriented LAMP can amplify the DNA fragment of the EGFR gene with codons 746-753 mutations within 30 min. Moreover, boiled cells can work as template resources. CONCLUSION: Mutation oriented-LAMP assay for EGFR gene mutation is sensitive on extracted DNA. This procedure would be capable of detecting EGFR gene mutation in sputum, pleural effusion, broncho-alveolar lavage fluid or trans-bronchial lung biopsy by chair side. PMID- 29599328 TI - Chemo-sensitivity of Two-dimensional Monolayer and Three-dimensional Spheroid of Breast Cancer MCF-7 Cells to Daunorubicin, Docetaxel, and Arsenic Disulfide. AB - BACKGROUND/AIM: Chemo-sensitivity of two-dimensional (2D) monolayers and three dimensional (3D) spheroids of human breast cancer MCF-7 cells were investigated. MATERIALS AND METHODS: MCF-7 cells were cultured in monolayers or spheroids established using a thermo-reversible gelatin polymer, in the presence of daunorubicin, docetaxel, or As2S2 Cell proliferation was examined by a Cell Counting Kit-8 assay. RESULTS: Daunorubicin, docetaxel, and As2S2 dose dependently decreased the MCF-7 cell proliferation in both 2D- and 3D-culture systems. The 3D spheroids were less sensitive to these agents than the 2D cultured cells. Verapamil, an inhibitor of P-glycoprotein, partially enhanced the antiproliferative effects of the agents. DL-buthionine-(S, R)-sulfoximine significantly increased (p<0.05), while N-acetyl-L-cysteine significantly inhibited the antiproliferative effects of As2S2 (p<0.003). CONCLUSION: The 3D spheroids showed less sensitivity to the antiprolliferative efficacies of anticancer agents than the 2D cultured cells. P-Glycoprotein is suggested to be partially implicated in drug resistance. Reduction of cellular glutathione level enhanced the As2S2 cytotoxicity. PMID- 29599329 TI - Additional Nodal Disease Prediction in Breast Cancer with Sentinel Lymph Node Metastasis Based on Clinicopathological Features. AB - AIM: The standard-of-care in breast cancer (BC) with positive sentinel lymph node (SLN) metastasis includes complete axillary lymph node dissection (ALND); however, almost half of such cases have no further tumor burden. This study aimed to assess the clinicopathological factors that predict non-SLN metastasis to define subgroups of SLN-positive patients in whom the axilla may be staged by SLN biopsy alone, while avoiding unnecessary overtreatment. PATIENTS AND METHODS: The records of 191 patients with histologically-proven primary BC who underwent a positive (SLN) biopsy between 2005 and 2017 were reviewed. Patients with at least one tumor-involved SLN who underwent completion ALND were enrolled. Demographic and clinicopathological characteristics, including age, primary tumor size and histological grade, lymphovascular invasion, ratio of positive SLNs to the harvested SLNs, SLN metastasis size, and molecular subtype classification according to immunohistochemical biomarker status [estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2)], were evaluated. Data were collected retrospectively and analyzed using the Mann Whitney and Chi-square tests (statistical significance: p<0.05). RESULTS: The incidence of non-SLN metastasis associated with positive SLN was 48.6% (93/191). The risk of additional nodal spread correlated with high sentinel nodal ratio >0.67 [odds ratio (OR)=2.55, p=0.032], luminal BC subtype (OR=2.67, p=0.06), HER2 overexpression (OR=0.4, p=0.016), and ER+PR-HER2- profile (OR=2.95, p=0.027). There was a tendency (statistically insignificant; p>0.05) toward higher incidence of non SLN metastasis with increasing age and histological grade, which could be attributed to the small sample size. CONCLUSION: According to this study, sentinel nodal ratio and BC subtypes as per ER, PR, and HER2 status significantly predicted the likelihood of additional lymphatic involvement. Validation of these parameters in prospective studies is indicated, and may help individualize treatment modalities. PMID- 29599330 TI - Amentoflavone Enhances the Therapeutic Efficacy of Sorafenib by Inhibiting Anti apoptotic Potential and Potentiating Apoptosis in Hepatocellular Carcinoma In Vivo. AB - BACKGROUND/AIM: In a previous study, we showed that amentoflavone promotes sorafenib-induced apoptosis in hepatocellular carcinoma (HCC) cells in vitro. However, whether amentoflavone augments anticancer efficacy of sorafenib in HCC in vivo is unknown. The aim of the present study was to verify the anticancer effect of amentoflavone combined with sorafenib in HCC in vivo. MATERIALS AND METHODS: HCC SK-Hep1 tumor-bearing mice were treated with vehicle, sorafenib, amentoflavone, or combination for 14 days, respectively. Effect of sorafenib, amentoflavone, or their combination on tumor growth, anti-apoptotic potential, apoptotic signaling and general toxicity were evaluated with digital caliper, immunohistochemistry staining and body weight. RESULTS: Our results demonstrated that amentoflavone significantly enhanced sorafenib-inhibited tumor growth and expression of ERK/AKT phosphorylation and anti-apoptotic proteins compared to single-agent treatment. Additionally, amentoflavone also triggered sorafenib induced apoptosis through extrinsic and intrinsic apoptotic pathways. CONCLUSION: Amentoflavone boosts therapeutic efficacy of sorafenib through blockage of anti apoptotic potential and induction of apoptosis in HCC in vivo. PMID- 29599331 TI - Isochlorogenic Acid C Reverses Epithelial-Mesenchymal Transition via Down regulation of EGFR Pathway in MDA-MB-231 cells. AB - BACKGROUND/AIM: Epidermal growth factor receptor (EGFR) has been suggested to play an important role in survival, proliferation, migration, differentiation, and tumorigenesis of many cell types. Breast cancer patients with high EGFR expression have a poor prognosis. In this study, we investigated the molecular mechanism of the inhibitory effect of isochlorogenic acid c (ICAC) extracted from Lonicera japonica on elevated EGFR levels of the triple-negative breast cancer (TNBC) cell line, MDA-MB-231. MATERIALS AND METHODS: The cell viability and cell cycle analysis were evaluated using 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl 2H-tetrazolium bromide (MTT) assay and flow cytometry, respectively. The migration ability and invasiveness of ICAC-treated MDA-MB-231 were examined by migration and Matrigel invasion assay. The epithelial-mesenchymal-transition (EMT)-related protein expression was examined by western blotting and reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: ICAC led to significant morphological changes and suppressed migration and invasion capacities of highly metastatic MDA-MB-231 cells. Western blot analysis for EGFR/EMT-associated proteins suggested that ICAC attenuated the mesenchymal traits as observed by up-regulation of epithelial markers and down-regulation of mesenchymal markers as well as decreased activities of matrix metalloproteinase-9 (MMP-9). CONCLUSION: These results suggested that the inhibitory effects of ICAC against EGFR-induced EMT and MDA-MB-231 cell invasion were dependent on the EGFR/ phospholipase Cgamma (PLCgamma)/extracellular regulated protein kinase 1/2 (ERK1/2)/slug signaling pathway. Therefore, the obtained results could provide us clues for the next therapeutic strategy in the treatment of TNBC. PMID- 29599332 TI - Phenethyl Isothiocyanate Induces Apoptotic Cell Death Through the Mitochondria dependent Pathway in Gefitinib-resistant NCI-H460 Human Lung Cancer Cells In Vitro. AB - BACKGROUND/AIM: Some lung cancer patients treated with gefitinib develop resistance to this drug resulting in unsatisfactory treatment outcomes. Phenethyl isothiocyanate (PEITC), present in our common cruciferous vegetables, exhibits anticancer activities in many human cancer cell lines. Currently, there is no available information on the possible modification of gefitinib resistance of lung cancer in vitro by PEITC. Thus, the effects of PEITC on gefitinib resistant lung cancer NCI-H460 cells were investigated in vitro. MATERIALS AND METHODS: The total cell viability, apoptotic cell death, production of reactive oxygen species (ROS) and Ca2+, levels of mitochondria membrane potential (DeltaPsim) and caspase 3, -8 and -9 activities were measured by flow cytometry assay. PEITC induced chromatin condensation was examined by DAPI staining. RESULTS: PEITC-induced cell morphological changes, decreased total viable cell number and induced apoptotic cell death in NCI-H460 and NCI-H460/G cells. PEITC decreased ROS production in NCI-H460 cells, but increased production in NCI-H460/G cells. PEITC increased Ca2+ production, decreased the levels of DeltaPsim and increased caspase-3, -8 and -9 activities in both NCI-H460 and NCI-H460/G cells. Western blotting was used to examine the effect of apoptotic cell death associated protein expression in NCI-H460 NCI-H460/G cells after exposure to PEITC. Results showed that PEITC increased expression of cleaved caspase-3, PARP, GADD153, Endo G and pro apoptotic protein Bax in NCI-H460/G cells. CONCLUSION: Based on these results, we suggest that PEITC induces apoptotic cell death via the caspase- and mitochondria dependent pathway in NCI-H460/G cells. PMID- 29599333 TI - Frequency of the Loss of Heterozygosity of the NF2 Gene in Sporadic Spinal Schwannomas. AB - BACKGROUND/AIM: Individuals with type 2 Neurofibromatosis are predisposed for the appearance of schwannomas. In the present study we analyzed the loss of heterozygosity and mutations in the NF2 gene in patients with sporadic Schwannoma without Neurofibromatosis type 2. MATERIALS AND METHODS: We analyzed 39 patients with sporadic spinal schwannoma. We quantified the number of alleles by FISH and sequenced the NF2 gene. RESULTS: We identified 16/39 patients with point mutations and/or LOHs in the tumor samples analyzed. The LOHs were found in 7/39 patients. Two homozygous mutations were detected in 4/39 tumors, and the presence of the mutation in heterozygosis was revealed in 3/39 patients. In two tumors, we detected the loss of one allele of the NF2 gene, with no mutation. CONCLUSION: The genetic alterations observed in the NF2 gene indicated that spinal schwannomas are associated with genetic alterations also found in other schwannomas and type 2 Neurofibromatosis, which reinforces the etiological role of this gene. PMID- 29599334 TI - Evaluation of Shape and Textural Features from CT as Prognostic Biomarkers in Non small Cell Lung Cancer. AB - BACKGROUND/AIM: We retrospectively investigated the prognostic potential (correlation with overall survival) of 9 shape and 21 textural features from non contrast-enhanced computed tomography (CT) in patients with non-small-cell lung cancer. MATERIALS AND METHODS: We considered a public dataset of 203 individuals with inoperable, histologically- or cytologically-confirmed NSCLC. Three dimensional shape and textural features from CT were computed using proprietary code and their prognostic potential evaluated through four different statistical protocols. RESULTS: Volume and grey-level run length matrix (GLRLM) run length non-uniformity were the only two features to pass all four protocols. Both features correlated negatively with overall survival. The results also showed a strong dependence on the evaluation protocol used. CONCLUSION: Tumour volume and GLRLM run-length non-uniformity from CT were the best predictor of survival in patients with non-small-cell lung cancer. We did not find enough evidence to claim a relationship with survival for the other features. PMID- 29599335 TI - Hyperforin Suppresses Tumor Growth and NF-kappaB-mediated Anti-apoptotic and Invasive Potential of Non-small Cell Lung Cancer. AB - BACKGROUND/AIM: Previous studies have indicated that hyperforin inhibits tumor growth of hepatocellular carcinoma. However, the anticancer effects of hyperforin in non-small cell lung cancer (NSCLC) are ambiguous. The aim of the present study was to investigate the anticancer effect of hyperforin in NSCLC. NSCLC CL1-5-F4 cells were treated with different concentrations of hyperforin or NF-kappaB inhibitor (QNZ) for different time periods. MATERIALS AND METHODS: Change of cell viability, NF-kappaB activation, apoptotic signaling pathways, expression of anti apoptotic proteins, and cell invasion were detected using the 3-(4,5 Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, NF-kappaB reporter gene assay, flow cytometry, western blotting, and cell invasion assay. RESULTS: The results demonstrated that hyperforin significantly promotes extrinsic and intrinsic apoptotic pathways, and inhibits cell viability and NF kappaB activation. In addition, results also indicated that blockage of NF-kappaB activation reduces the levels of anti-apoptotic proteins and cell invasion in CL1 5-F4 cells. CONCLUSION: These results suggested hyperforin induces apoptosis and inhibits NF-kappaB-modulated anti-apoptotic and invasive potential in NSCLC. PMID- 29599336 TI - Glycine Is a Predictor for a Suppressive Effect of Fucoxanthinol on Colonosphere Formation Under Hypoxia. AB - BACKGROUND/AIM: Fucoxanthinol (FxOH), a metabolite of fucoxanthin, is known to inhibit tumorigenicity of human colorectal cancer stem cells (CCSCs) and their sphere formation. Hypoxic conditions and hypoxia-inducible factors (HIFs) are essential to maintain the stemness of CCSCs. We investigated effects of FxOH on sphere formation, intercellular energy metabolites in colonospheres formed from human colorectal HT-29 cells under hypoxic conditions. RESULTS: FxOH at 50 MUM suppressed HIF1alpha expression and activation of integrin, mitogen-activated protein kinase (MAPK), Wingless/integrated (WNT) and signal transducer and activator of transcription (STAT) signals. Moreover, expression of epithelial mesenchymal transition- and apoptosis-related proteins in the colonospheres was lowered by FxOH. The level of glycine was reduced in hypoxic colonospheres under FxOH treatment. CONCLUSION: FxOH attenuated the sphere formation of hypoxic colonospheres, in part, by suppressing HIF1alpha expression. Glycine could be a potential predictor for the activity of agents that inhibit sphere formation by hypoxic colonospheres. PMID- 29599337 TI - The Association of Matrix Metalloproteinase-8 Promoter Genotypes in Breast Cancer. AB - BACKGROUND/AIM: The family of matrix metalloproteinases (MMPs) controls homeostasis of the extracellular matrix and their genetic polymorphisms may be associated with personal cancer susceptibility. The serum levels of MMP8 was reported to be higher in patients with breast cancer than in healthy individuals. In this study, we aimed to investigate the contribution of a polymorphism in the promoter region of MMP8 (-799C/T) and two nonsynonymous polymorphisms (Val436Ala and Lys460Thr) to breast cancer. MATERIALS AND METHODS: MMP8 -799C/T, Val436Ala and Lys460Thr polymorphic genotypes were determined for 1,232 patients with breast cancer and 1,232 healthy controls by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS: The odds ratios (ORs) after adjusting for age, gender, smoking and alcohol drinking status for those carrying CT and TT genotypes at the MMP8 promoter C-799T were 1.03 (95% CI=0.88-1.23, p=0.7475) and 1.08 (95% CI=0.91-1.53, p=0.3561), respectively, compared to those carrying the wild-type CC genotype. The OR for the combined T-bearing genotypes were of a similar non-significant level (OR=1.05, 95% CI=0.90-1.26, p=0.5176). Supporting this finding, the adjusted OR for those carrying the T allele at MMP8 C-799T was 1.05 (95% CI=0.86-1.21, p=0.3797), compared to those carrying the wild type C allele. There was also no significant association of MMP8 Lys460Thr with breast cancer. There was no polymorphic genotype at MMP8 Val436Ala found among any of the investigated individuals. CONCLUSION: MMP8 -799C/T, Val436Ala and Lys460Thr polymorphisms may only play an indirect role in determining personal cancer susceptibility to breast cancer in Taiwan. PMID- 29599338 TI - TRAP1 Inhibition Increases Glutamine Synthetase Activity in Glutamine Auxotrophic Non-small Cell Lung Cancer Cells. AB - BACKGROUND/AIM: Cancer cells are distinct in terms of glutamine dependence. Here we investigated the different susceptibility of glutamine-independent and glutamine-dependent non-small cell lung cancer (NSCLC) to treatment with tumor necrosis factor receptor-associated protein 1 (TRAP1) inhibitor gamitrinib triphenylphosphonium (G-TPP). MATERIALS AND METHODS: Cell viability and proliferation under glutamine deprivation and G-TPP treatment were determined by the MTT and colony-formation assays. Protein and mRNA expression were determined by western blot and quantitative polymerase chain reaction. Colorimetric-based assay was performed to check for glutamine synthetase (GS) activity. RESULTS: NSCLC cells showed diverse adaptation under glutamine-depleted condition and were categorized into glutamine-independent and glutamine-dependent cells. Treatment with G-TPP particularly increased GS activity and induced cell death due to energy shortage indicated by phosphorylated AMP-activated protein kinase (AMPK) in glutamine-dependent cells. CONCLUSION: This finding provides better understanding of TRAP1-mediated glutamine metabolism through GS activity, and evidence that TRAP1 could be a promising therapeutic target for glutamine addicted cancer. PMID- 29599339 TI - Depth of Muscularis Propria Invasion Does Not Prognosticate Survival in T2 Esophageal Adenocarcinoma. AB - AIM: Although tumor depth of invasion is strongly associated with risk of lymph node metastasis and long-term survival in patients with esophageal adenocarcinoma, the significance of differential T2 invasion (inner circular layer versus outer longitudinal layer) is unknown. The current study was undertaken to explore the hypothesis that greater T2-specific depth of invasion is associated with inferior long-term outcomes in patients with esophageal adenocarcinoma treated with esophagectomy. PATIENTS AND METHODS: Demographic, treatment, and outcome data were collected for patients with resected pT2N0-3M0 esophageal adenocarcinoma treated between 2005 and 2015 pooled from four U.S. academic medical centers. Two blinded pathologists evaluated depth of muscularis propria tumor invasion. Univariate and Cox proportional hazard regression analyses were performed to identify prognostic factors for overall (OS) and disease-free (DFS) survival, and Kaplan-Meier analysis to compare survival differences specific to prognostic factors. RESULTS: A total of 84 patients were identified for analysis (53 with circular invasion; 31 with longitudinal invasion), with a median age of 66 years. Sixty percent of patients (50/84) received induction therapy prior to esophagectomy. The median OS and DFS was 58 months (95% confidence interval(CI)=42 months-not reached) and 27 months (95% CI=13.7-66 months) respectively. Depth of muscularis propria invasion did not correlate with OS or DFS on univariate (p=0.42; and p=0.34, respectively) or multivariate (p=0.15 and p=0.21, respectively) analysis after adjustment for age, nodal status, perineural invasion, and tumor grade. These findings did not vary by induction therapy status. CONCLUSION: Depth of muscularis propria invasion does not appear to correlate with survival in patients with esophageal adenocarcinoma. PMID- 29599340 TI - Myelodysplastic Syndrome and Sweet's Syndrome Are Associated with a Mutation in Isocitrate Dehydrogenase 1. AB - BACKGROUND: Sweet's syndrome (SS) is a febrile neutrophilic dermatosis that has been clinically linked to hematological malignancies, particularly myelodysplastic syndrome (MDS), in a number of case series. Many epigenetic changes underlying MDS have been identified, such as a mutation in the isocitrate dehydrogenase 1 (IDH1) gene, which causes DNA hypermethylation and alteration of a number of genes that lead to leukemogenesis. However, the pathogenesis of malignancy-associated SS is unknown. CASE REPORT: We present two patients who were diagnosed with SS and concomitant IDH1-mutated MDS. Immunohistochemical staining of their skin lesions showed neutrophils diffusely positive for the IDH1 mutation. CONCLUSION: These cases demonstrate that IDH1 mutation may be implicated in the pathogenesis of malignancy-associated SS. Future investigation to elucidate this pathway is warranted. Establishing this molecular link can provide an earlier identification of patients with SS who are also at increased risk for developing MDS. PMID- 29599341 TI - Radiotherapy-induced Early ECG Changes and Their Comparison with Echocardiography in Patients with Early-stage Breast Cancer. AB - BACKGROUND: Early electrocardiogram (ECG) changes after breast cancer radiotherapy (RT) have been reported, but their characteristics and associated factors are largely unknown. This study aimed to explore early RT-induced ECG changes and to compare them with echocardiography changes. MATERIALS AND METHODS: Sixty eligible patients with chemotherapy-naive left-sided and 20 with right sided breast cancer were evaluated with echocardiography, blood samples and ECG before and after RT. RESULTS: RT-induced ECG changes in the anterior leads. T Wave changes were most frequent. T-Wave decline was associated independently with patient age (beta=-0.245, p=0.005), mean heart radiation dose (beta=1.252, p=0.001) and global systolic strain rate change (beta=7.943, p=0.002). T-Wave inversion was associated independently with mean heart radiation dose (beta=0.143, p<0.001), global longitudinal strain change (beta=0.053, p=0.017) and posterior calibrated integrated backscatter (beta=-0.022, p=0.049). CONCLUSION: RT-induced ECG changes were prevalent and associated with functional and structural changes in echocardiography. ECG could be used for post-RT cardiac screening. PMID- 29599342 TI - WT1-pulsed Dendritic Cell Vaccine Combined with Chemotherapy for Resected Pancreatic Cancer in a Phase I Study. AB - BACKGROUND/AIM: Wilms' tumor 1 (WT1) is a tumor-associated antigen highly expressed in cancer. We examined the safety of WT1-peptide pulsed dendritic cell (WT1-DC) vaccine in combination with chemotherapy in patients with surgically resected pancreatic cancer. PATIENTS AND METHODS: Eight patients with resectable pancreatic cancer undergoing surgery either combined with S-1 or S-1 plus gemcitabine therapy were enrolled. Immunohistochemical analysis of WT1 was performed in 34 cases of pancreatic cancer. RESULTS: No serious side-effects were observed, except grade I fever in five and grade I reactions at the injection site in all patients. WT1-specific cytotoxic T-lymphocytes were detected in seven patients, and WT1 and human leukocyte antigen class I antigens were positive in all 34 cases. CONCLUSION: Our study clarified the safety and potential acquisition of immunity after vaccination targeting WT1. Further efficacy of WT1 DC vaccine to improve prognosis would be determined by a prospective clinical trial for resectable pancreatic cancer. PMID- 29599343 TI - Feasibility and Immune Response of WT1 Peptide Vaccination in Combination with OK 432 for Paediatric Solid Tumors. AB - BACKGROUND/AIM: Wilms' tumor 1 (WT1) peptide-based vaccination has been reported for its potential usefulness in targeting several cancers. The adjuvant drug OK 432 is known to have potent immunomodulation and therapeutic properties when applied in cancer treatment and may, thus, be important to trigger the appropriate immunological response in paediatric patients with a solid tumor that are vaccinated with a WT1 peptide. PATIENTS AND METHODS: Paediatric patients with a solid tumor were vaccinated with a WT1 peptide and OK-432 once every 2 weeks, for a total of seven times. RESULTS: Of the 24 patients, 18 completed the scheduled vaccinations. Sixteen patients had local skin symptoms and/or fever. In 1 patient, anaphylactic symptoms emerged at the time of the final injection, but these quickly subsided after the treatment. WT1-specific immunological responses were observed in 4 patients (22.2%). WT1 and HLA class I expression were confirmed in 100% and 85% of primary tumors, respectively. CONCLUSION: WT1 peptide vaccine therapy combined with OK-432 appears to be relatively safe for children. However further studies in a larger number of patients are necessary to confirm its safety and efficacy. PMID- 29599344 TI - Racial Disparities in the Molecular Landscape of Cancer. AB - BACKGROUND/AIM: African Americans (AA) have the highest incidence and mortality of any racial/ethnic group in the US for most cancer types. Heterogeneity in the molecular biology of cancer, as a contributing factor to this disparity, is poorly understood. To address this gap in knowledge, we explored the molecular landscape of colorectal cancer (CRC), non-small cell lung cancer (NSCLC) and high grade glioma (HGG) from 271 AA and 636 Caucasian (CC) cases. MATERIALS AND METHODS: DNA from formalin-fixed paraffin-embedded tumors was sequenced using next-generation sequencing. Additionally, we evaluated protein expression using immunohistochemistry. The Exome Aggregation Consortium Database was evaluated for known ethnicity associations. RESULTS: Considering only pathogenic or presumed pathogenic mutations, as determined by the American College of Medical Genetics and Genomics guidelines, and using Bonferroni and Benjamini-Hochberg corrections for multiple comparisons, we found that CRC tumors from AA patients harbored significantly more mutations of phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) than those from CC patients. CRC tumors in AA patients also appeared to harbor more mutations of mitogen-activated protein kinase kinase 1 (MAP2K1/MEK1), MPL proto-oncogene (MPL), thrombo-poietin receptor, and neurofibromin 1 (NF1) than those from CC patients. In contrast, CRCs from AA patients were likely to carry fewer mutations of ataxia telangiectasia mutated (ATM), as well as of proto-oncogene B-Raf (BRAF), including the V600E variant, than those from CC patients. Rates of immunohistochemical positivity for epidermal growth factor receptor (EGFR) and DNA topoisomerase 2-alpha (TOP2A) tended to be higher in CRCs from AA patients than in CC patients. In NSCLC adenocarcinoma, BRAF variants appeared to be more frequent in the AA than in the CC cohort, whereas in squamous cell lung carcinoma, programmed death-ligand 1 (PD-L1) expression tended to be lower in the AA than in CC group. Moreover, HGG tumors from AA patients showed a trend toward harboring more mutations of protein tyrosine phosphatase non-receptor 11 (PTPN11), than HGG tumors from the CC cohort. In contrast, mutations of phosphatase and tensin homolog (PTEN) and tumor protein 53 (TP53) appeared to be higher in HGG tumors in CC patients than in their AA counterparts. CONCLUSION: Our data revealed significant differences and trends in molecular signatures of the three cancer types in AA and CC cohorts. These findings imply that there may be differences in carcinogenesis between AA and CC patients and that race may be a factor that should be considered regarding cancer incidence and outcome. PMID- 29599345 TI - Significance of Perioperative Chemotherapy in Squamous Cell Carcinoma of the Upper and Lower Urinary Tract. AB - BACKGROUND/AIM: To evaluate the clinicopathological characteristics and prognosis of squamous cell carcinoma (SCC) of the urinary tract (UT) urothelium, and investigate the utility of perioperative chemotherapy. PATIENTS AND METHODS: Thirty-three patients diagnosed with SCC in renal pelvis, ureter and bladder at the Kanazawa University between 2007 and 2017 were included in this retrospective study. Cancer-specific survival (CSS) rates according to cancer stage and neoadjuvant chemotherapy (NAC) were determined. RESULTS: Among the entire cohort, two-year CSS rates were 100%, 75%, 47% and 0% in stages I, II, III and IV, respectively, with a significant correlation between CSS and cancer stage (p=0.0063). Sixteen patients underwent radical surgery, and seven patients received NAC; however, there were no significant differences in CSS rates among patients stratified by NAC (p=0.7043). CONCLUSION: Worse cancer stage for SCC of UT urothelium was associated with worse prognosis. Given the poor efficacy of NAC in these patients, surgical treatment should be preferred. PMID- 29599346 TI - Bevacizumab Does Not Reduce the Lymphocele Rate in Advanced Ovarian Cancer After Complete Cytoreductive Surgery. AB - BACKGROUND/AIM: We aimed to evaluate the impact of bevacizumab on the lymphocele rate in patients after complete cytoreductive surgery for advanced ovarian cancer. PATIENTS AND METHODS: This retrospective study included patients with advanced ovarian cancer who had undergone complete cytoreductive surgery with pelvic and para-aortic lymphadenectomy at the Gustave Roussy Institute from 2005 to 2014. The introduction of bevacizumab was discussed in a multidisciplinary meeting. RESULTS: During the study period, 247 patients were included; 24.6% of patients (61 patients) received adjuvant bevacizumab. The rate of symptomatic lymphocele was 34% (84 patients). In the lymphocele group, patients tended to receive adjuvant bevacizumab more often than did the control group (32% and 21%, respectively, p=0.05). In multivariate analysis, bevacizumab was not significantly associated with the risk of symptomatic lymphocele (hazard ratio(HR)=1.62, 95% confidence interval(CI)=0.87-3.01, p=0.12). CONCLUSION: Adjuvant bevacizumab has no impact on the formation or duration of symptomatic lymphocele in patients after complete cytoreductive surgery for advanced ovarian cancer. PMID- 29599347 TI - Morphological Classification of Corrupted Colonic Crypts in Ulcerative Colitis. AB - BACKGROUND/AIM: In ulcerative colitis (UC) the colonic mucosa shows, in addition to a high number of inflammatory cells, crypts with architectural distortions, called corrupted colonic crypts (CCC). Here we classify the histologic repertoire and assess the frequency of CCC in UC. PATIENTS AND METHODS: Five-hundred and sixteen histologic sections from 29 colectomy specimens with UC (24 having adenocarcinoma and five, high-grade dysplasia, HGD) were reviewed. RESULTS: The vast majority of the colonic mucosa portrayed countless crypts with normal shapes (CNS) lined with normal epithelium, except for 45 CNS: 28 showed inconclusive suspected cellular changes (ISCC), and 17, high-grade dysplasia (HGD). CCC were subdivided into four groups: i) Crypts with fission distortions, ii) Crypts with length distortions, iii) Crypts with outline distortions and iv) Crypts with axial polarity distortions. The most frequent CCC group had axial polarity distortions (33.4%), and the less frequent CCC group, outline distortions (21.1%) (p<0.05). No apparent differences in frequency between groups were found in colectomies with HGD/carcinoma, or in colectomies preformed for medically refractory UC without HGD/carcinoma. Out of the 902 CCC present in the specimens, 343 (38.0%) displayed ISCC, 186 (20.6%) HGD, and the remaining 373 (41.4%) normal epithelium. Hence, of the 203 crypts exhibiting HGD, 186 (91.6%) were CCC and the remaining 17 (8.4%) CNS (p<0.05). CONCLUSION: Based on these findings it is suggested that the microscopic search for HGD in UC colectomy-specimens should preferentially be focused on mucosal areas exhibiting CCC. This view is validated by recent findings showing that p53 overexpression (a biomarker of epithelial carcinogenesis) significantly correlated with architectural distortions of the crypts in UC. PMID- 29599348 TI - Expression of Estrogen Receptor-alpha and Survival in Advanced-stage Non-small Cell Lung Cancer. AB - BACKGROUND/AIM: The favorable prognosis of women with non-small-cell lung cancer (NSCLC) compared to men might be explained by sex hormone-related mechanisms. We investigated whether this observation could be explained by the expression of estrogen receptor-alpha (ER-alpha) in tumor tissue. MATERIALS AND METHODS: Archived, formalin fixed, paraffin embedded tumor tissue samples were retrospectively analyzed for nuclear expression of ER-alpha with immunohistochemistry. RESULTS: Biopsies from 222 patients were analyzed. Twenty three percent were ER-alpha positive. Fifty-four percent of the patients were men and 46% of the tumors were adenocarcinomas. One hundred-nine (49%) patients received pemetrexed and carboplatin and 113 (51%) received gemcitabine and carboplatin. Females with ER-alpha positive tumors who received PC had a substantial survival benefit over all other groups (20 vs. 4.6 months; p=0.003). CONCLUSION: ER-alpha is an independent prognostic factor in advanced NSCLC and might also be a predictive factor for response to pemetrexed/carboplatin in women. PMID- 29599349 TI - Patient-reported Symptom Burden, Rate of Completion of Palliative Radiotherapy and 30-day Mortality in Two Groups of Cancer Patients Managed With or Without Additional Care by a Multidisciplinary Palliative Care Team. AB - BACKGROUND/AIM: The aim of this study was to analyze differences in symptom burden, baseline and outcome parameters, including completion of palliative radiotherapy and 30-day mortality, between patients treated with palliative radiotherapy (RT) who were managed exclusively by regular oncology staff or a multidisciplinary palliative care team (MPCT) in addition. PATIENTS AND METHODS: This was a retrospective single-institution analysis. Comparison of two groups of patients: MPCT versus none (n=36 and 65, respectively). All patients provided Edmonton symptom assessment system (ESAS) data before RT. RESULTS: The MPCT group included significantly more patients with reduced performance status. Furthermore, these patients had higher ESAS symptom scores, except for two items (dyspnea, sleep). The largest differences were observed for pain, fatigue, anxiety and depression. The significant difference in pain scores was also reflected in different opioid medication rates. Failure to complete radiotherapy was more common in the MPCT group (11 and 2%, respectively, p=0.05). Thirty-day mortality was different, too (28 and 2%, respectively, p=0.0001). The Kaplan Meier survival curves were not significantly different (1-year survival rates 21 and 25%, respectively, p=0.27). CONCLUSION: The MPCT group was characterized by a higher symptom burden. Prognostic factors such as performance status were not balanced between the two groups. Despite this fact, actuarial overall survival was comparable. Given the high rate of 30-day mortality in the MPCT group, efforts to optimize criteria for initiation of radiotherapy are warranted. PMID- 29599350 TI - Periapical Cemento-osseous Dysplasia Is Rarely Diagnosed on Orthopantomograms of Patients with Neurofibromatosis Type 1 and Is Not a Gender-specific Feature of the Disease. AB - : Several skeletal aberrations of the skull have been described for the tumor predisposition syndrome neurofibromatosis type 1 (NF1). Recently, periapical cemental/cemento-osseous dysplasia (COD) has been described in females affected with NF1. This reactive lesion of the hard tissues in tooth-bearing areas of the jaw has been proposed to represent a gender-specific radiological feature of NF1. The aim of this study was to investigate the prevalence of COD in patients with NF1. PATIENTS AND METHODS: The orthopantomograms (OPGs) of 179 patients with a confirmed diagnosis of NF1 were analyzed for COD. The results were compared to radiographic findings obtained in OPGs of age- and sex-matched controls. The NF1 patient group was further differentiated according to the evidence of facial plexiform neurofibroma. RESULTS: COD was a very rare finding in both groups. The extension of the diagnostic criteria including radiologically-healthy teeth and a widened periodontal gap in the periapical area only marginally increased the number of considered cases. Although there was a somewhat more common occurrence of such changes in the patient group compared to the control group and the number of affected women was greater than the number of men, none of these differences reached statistical significance. Furthermore, COD or widening of the periradicular periodontal space was not found to be associated with facial tumor type in NF1. CONCLUSION: The investigation revealed that COD is not a diagnostic feature of NF1. There is no clear association of the rare finding of COD with gender. These studies should be compared with patient groups of other ethnic backgrounds. PMID- 29599351 TI - Analysis of HER Family (HER1-4) Expression as a Biomarker in Combination Therapy with Pertuzumab, Trastuzumab and Docetaxel for Advanced HER2-positive Breast Cancer. AB - BACKGROUND: Chemotherapy with trastuzumab, pertuzumab and docetaxel (TPD regimen) is now strongly recommended as a treatment option for first-line therapy for advanced human epidermal growth factor receptor (HER)2-positive breast cancer. In this study, we analyzed the expression of HER 1-4 proteins, and investigated whether or not their expression was predictive of the response of advanced HER2 positive breast cancer to chemotherapy with the TPD regimen. PATIENTS AND METHODS: The study consisted of 29 cases in which TPD regimen chemotherapy was carried out from September 2013 to November 2015. The expression levels of estrogen receptor (ER), progesterone receptor (PgR), Ki67, HER1, HER2, HER3 and HER4 were evaluated using immunostaining employing needle biopsy specimens. RESULTS: The overall response rate (ORR) was significantly higher in the HER3 positive group than in the HER3-negative group (p=0.002). In prognostic analysis, the HER3-positive group showed a significant progression-free survival extension over the HER3-negative group (p=0.042, log-rank). In univariate analysis, objective response (p=0.004, hazard ratio(HR)=0.123) and positive HER3 expression (p=0.023, HR=0.279) significantly contributed to extension of progression-free survival interval. CONCLUSION: HER3 expression may be a useful factor for predicting the response of HER2-positive breast cancer to chemotherapy with the TPD regimen. PMID- 29599352 TI - KDM4D Predicts Recurrence in Exocrine Pancreatic Cells of Resection Margins from Patients with Pancreatic Adenocarcinoma. AB - BACKGROUND/AIM: The role of histone demethylators, such as Jumonji domain 2 (JMJD2/KDM4) proteins, and histone deacetylases, such as sirtuins (SIRT) is poorly characterized in pancreatic carcinomas while they have a major role in the carcinogenesis of several other tumours. MATERIALS AND METHODS: We assessed retrospectively with immunohistochemistry the expressions of KDM4A, KDM4B and KDM4D in 81 and SIRT1-4 in 102 pancreatic adenocarcinomas. Immunostaining was evaluated separately in benign pancreatic tissues and in malignant cells. RESULTS: High nuclear KDM4D expression in benign pancreatic tissue from resection margins associated with dismal disease-free survival (DFS) (OR=8.00; 95%CI=1.87 33.9; p=0.005), even more significantly than tumour size and lymph node involvement. High cytoplasmic SIRT2 expression in benign pancreatic tissues also associated with a shorter DFS, but only in univariate analysis (p=0.026). CONCLUSION: Nuclear KDM4D and SIRT2 expression deviated from that of benign pancreatic tissue thus putatively influencing gene expression of tumor cells. Regardless, none of the enzymes studied had a decisive role in the spread of pancreatic cancer. A high nuclear expression of KDM4D in samples of pancreatic resection margins significantly and independently predicted an earlier recurrence and could thus be used in the assessment of risk of relapse in clinical practice. PMID- 29599353 TI - Long-term Results of External Beam Radiotherapy for Prostate Cancer with Prostate specific Antigen of More Than 50 ng/ml and Without Evidence of Lymph Node or Distant Metastasis. AB - BACKGROUND/AIM: To evaluate long-term treatment outcomes of external beam radiotherapy for prostate cancer with a pretreatment prostate-specific antigen (PSA) level of more than 50 ng/ml and without evidence of lymph node or distant metastasis. PATIENTS AND METHODS: Definitive radiotherapy of 66 Gy or 72 Gy in combination with androgen deprivation therapy (ADT) was performed. PSA relapse free survival (PRFS), distant metastasis-free survival (DMFS), cause-specific survival (CSS), and overall survival (OS) were evaluated. The impact of prognostic factors on PRFS, DMFS, CSS, and OS was analyzed in univariate and multivariate analyses. RESULTS: One hundred twenty patients with a median follow up period of 92.6 months were analyzed in this study. The median duration of ADT was 11.0 months. The 5- and 8-year PRFS rates in all patients were 65.1% and 48.5%, respectively. The 8-year DMFS, CSS, and OS rates in all patients were 84.0%, 93.4%, and 81.6%, respectively. Both in univariate and multivariate analyses, Gleason score (GS) and radiotherapy dose were significant prognostic factors (p=0.015 and 0.001). There was no significant difference between each prognostic factor in DMFS, CSS, and OS. CONCLUSION: We might have indicated the significance of definitive radiotherapy even for prostate cancer with PSA of more than 50 ng/ml and without evidence of metastasis. PMID- 29599354 TI - Prediction of Treatment Response to Neoadjuvant Chemotherapy in Breast Cancer by Subtype Using Tumor-infiltrating Lymphocytes. AB - BACKGROUND/AIM: Recent interest has focused on the significance of tumor infiltrating lymphocytes (TILs) on the efficacies and outcomes of the treatment in breast cancer (BC). Based on the recent international recommendation to standardize the evaluation method, the clinical validity and utility of TILs in patients who underwent neoadjuvant chemotherapy (NAC) were investigated in the present study. PATIENTS AND METHODS: TILs were evaluated in 177 patients with BC treated with NAC and subsequent curative surgery. The correlation between TILs evaluated according to the standard method and prognosis, including the efficacy of NAC, was investigated retrospectively. RESULTS: In the high-TIL group (n=96) compared to the low-TIL group (n=81), triple-negative breast cancer (TNBC) (p<0.001) and human epidermal growth factor receptor 2-enriched breast cancer (HER2BC) (p=0.040) were significantly more frequent, and the pathological complete response (pCR) rate was significantly higher (p=0.003). Among patients with TNBC and those with HER2BC, the pCR rate was significantly higher in the high-TIL group than in the low-TIL group (p=0.013 and p=0.014, respectively). Multivariable analysis also showed that high-TIL status was an independent factor predicting favorable prognosis (hazard ratio(HR)=0.24, p=0.023 and HR=0.13, p=0.036). Biopsy specimens from local recurrence after successful NAC frequently showed TILs decreased. CONCLUSION: TILs may be a biomarker for predicting treatment response to NAC in patients with TNBC and HER2BC. A decrease in TILs may also be associated with tumor recurrence. PMID- 29599355 TI - Innovations for Cervical Esophagogastrostomy in Thoracic Esophageal Cancer Operations. AB - Three-field lymph node dissection is now performed in operations for advanced thoracic esophageal cancer, with an associated improvement in outcomes. However, reconstructive surgery following resection of the esophagus is frequently associated with the occurrence of anastomotic leakage. Once it occurs, major problems can arise such as decreased quality of life, protracted hospitalization, or even death. This is why there has been a large number of innovations in and modifications to reconstructive surgery. The standard procedures in our Department for advanced thoracic esophageal cancer are subtotal esophagectomy and three-field lymph node dissection. The thin gastric tube along the greater curvature is used as the reconstructed organ in reconstructive surgery, performing a cervical esophagogastrostomy. Innovations have been made to reconstructive surgery in order to prevent anastomotic leakage. This procedure markedly reduces anastomotic leakage, and also reduces anastomotic stricture, which likely makes it an extremely useful procedure that any surgeon can perform. PMID- 29599356 TI - Prognostic Value of Albumin/Globulin Ratio in Patients with Upper Tract Urothelial Carcinoma Patients Treated with Radical Nephroureterectomy. AB - BACKGROUND/AIM: We investigated the prognostic role of the albumin/globulin ratio (AGR) in patients with upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). PATIENTS AND METHODS: AGR was calculated as follows: AGR=serum albumin/(serum total protein-serum albumin). Associations of preoperative AGR with disease-free (DFS) and overall (OS) survival were assessed in 105 patients with UTUC undergoing RNU. RESULTS: Patients with preoperative AGR <1.24 and >=1.24 were classified into the low (n=46, 44%) and high (n=59, 56%) groups, respectively. The 5-year DFS and OS were 77% and 78%, respectively. On multivariate analysis, high preoperative AGR was an independent predictor for both better DFS (hazard ratio(HR)=0.34, p=0.038) and OS (HR=0.24, p=0.006). The 5 year DFS and OS were significantly longer in the high-AGR group than in the low AGR group (90% vs. 60%; 89% vs. 65%, both p<0.001). CONCLUSION: The AGR has prognostic value in patients with UTUC undergoing RNU. PMID- 29599357 TI - Gastric Cancer of "Crawling Type" Detected by Additional Gastrectomy After Endoscopic Submucosal Resection. AB - "Crawling type" gastric cancer (GC) is known as a rare variant of early GCs, which is difficult to diagnose at an early stage because of low-grade nuclear atypia and a morphology mimicking intestinal metaplasia. This is a case report of a 69-year-old woman who was diagnosed with early-stage gastric cancer. She had endoscopic submucosal resection (ESD) and histologically, both horizontal and vertical margins were negative. Seven months after ESD, a new lesion of the stomach was detected by follow-up gastroscopy. Laparoscopic distal gastrectomy was performed and "crawling type" glands were observed throughout the whole area of the tumor. We should keep this variant in mind, especially when a tumor is superficial depressed or superficial flat type in the middle of the stomach. Careful observation with multiple biopsies of all mucosal layer and a re-biopsy is the key procedure for obtaining the right diagnosis. Endoscopic and histological characteristics should also be reviewed. PMID- 29599358 TI - Numerical Imbalances of Chromosome 7 in Oral Squamous Cell Carcinoma. AB - BACKGROUND: Oral squamous cell carcinoma (OSCC) is an aggressive neoplasm. Many chromosomal and gene alterations have been identified in OSCC, including structural and numerical changes. In this study, we implemented a molecular assay of chromosome 7 (Chr7) in order to investigate the level of its numerical instability in OSCC. MATERIALS AND METHODS: Using tissue microarray technology, 30 primary OSCCs were cored and re-embedded into one recipient block. Chromogenic in situ hybridization assay was performed based on Chr7 centromeric probedetection. RESULTS: Chr 7 numerical analysis detected polysomy (trisomy/ tetrasomy) in 4/30 (13.3%) of the examined tissue OSCC cores. Statistical significance was assessed correlating Chr7 numerical aberrations with stage (p=0.015), especially detected in cases not related to human papillomavirus (HPV) (p=0.01). CONCLUSION: Although Chr7 polysomy is a relatively rare gross genetic event in OSSC, it affects their biological behavior leading toa progressively aggressive phenotype (advanced stage). Furthermore, Chr7 polysomy is observed more frequently in non-viral (HPV) cases. PMID- 29599359 TI - Clinicopathological Aspects and Diagnostic Problems in Patients with Intraductal Papillary Neoplasm of the Bile Duct. AB - BACKGROUND/AIM: Intraductal papillary neoplasm of the bile duct (IPNB) is defined as a non-invasive malignancy and disparity of its histological diagnosis with related diseases remains. PATIENTS AND METHODS: Twenty-six cases of IPNB and 12 of papillary adenocarcinomas (PAC) at two Institutes were investigated. RESULTS: The prevalence of biliary dilatation and mucin secretion in the group with IPNB was significantly higher compared to the group with PAC (p<0.01). IPNB was predominantly located in the proximal bile duct compared to the location of PAC (p<0.01). Mis-matching of a second histological diagnosis was observed in 27% of IPNB and 25% of PAC, respectively. The prevalence of tumor relapse was significantly higher in PAC than in IPNB (p<0.05), and the overall survival was significantly better in IPNB than in PAC (p<0.01). CONCLUSION: Although IPNB is currently defined under histological criteria, morphologies were various and disparity in histological diagnosis for IPNB remains problematic when the clinical strategy is contemplated. PMID- 29599360 TI - Transient Exocrine Pancreatic Insufficiency: First Report of an Unrecognized Complication of Cytoreductive Surgery and HIPEC. AB - BACKGROUND: As cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are being increasingly adopted as the standard treatment for peritoneal surface malignancies, familiarity with this procedure's adverse events is also growing. Herein, we describe an unreported adverse event of exocrine pancreatic insufficiency (EPI) following CRS and HIPEC. PATIENTS AND METHODS: Patients who underwent CRS and HIPEC between 9/2016 and 9/2017 were prospectively recruited. Fecal elastase-1 (FE1) and Clostridium difficile toxins were tested in all patients in the immediate postoperative period. Patients with diarrhea who had low FE1 were started on oral pancreatic enzyme replacement therapy (PERT) and their symptomatic progression was followed. RESULTS: A total of 26 patients were included. Eleven patients (42.31%) developed postoperative refractory diarrhea, nine of whom had a low FE1 level. These patients were treated with PERT either directly or after completion of antibiotics course if C. difficile toxin was positive. Eight patients demonstrated symptomatic resolution of their diarrhea, and thus the diagnosis of EPI was established (30.77%). Patients with diarrhea had lower FE1 levels, and were more likely to have had a terminal ileum resection and had a longer hospital stay. Regression analysis identified the rapid rise of a patient's core temperature by >1 degrees C within 15 minutes as the sole predictor of EPI occurrence. CONCLUSION: EPI is a potential adverse event following CRS and HIPEC and might be largely responsible for refractory diarrhea. In our patients with refractory diarrhea and low FE1, PERT provided immediate symptomatic relief. The biological basis of this phenomenon remains unclear and warrants further investigation. PMID- 29599361 TI - The Clinical Usefulness of the LigaSureTM Small Jaw in Axillary Lymph Node Dissection in Patients with Breast Cancer. AB - BACKGROUND: The LigaSureTM small jaw (LS-SJ) multifunctional tissue sealing system is mainly used in cervical operations. We aimed to evaluate the clinical efficacy of the LS-SJ in axillary lymph node dissection (ALND) in comparison to the conventional method. PATIENTS AND METHODS: Ninety-two patients with breast cancer who underwent total mastectomy and ALND were included in this study. The patients were divided into the LS-SJ group (n=43) and the conventional-ALND (c ALND) group (n=49). RESULTS: Patients with high body mass index values had a greater drainage volume and longer time to drain removal. The drainage volume was in the LS-SJ group was significantly lower than that in the c-ALND group. The time to drain removal and the hospitalization period were also significantly shorter in the LS-SJ group. The LS-SJ was more effective for ALND in obese patients. CONCLUSION: The results suggest the clinical usefulness of LS-SJ in ALND in patients with breast cancer, especially in obese patients. PMID- 29599362 TI - Curative Gastrectomy with Perioperative Chemotherapy Improves the Survival for Unresectable Gastric Cancer. AB - BACKGROUND/AIM: Although there are a few reports recommending gastrectomy for unresectable gastric cancer (UGC) to improve survival, the advantage of gastrectomy remains unclear. The objective of this study was to assess the meanings of the surgical intervention. PATIENTS AND METHODS: Therapeutic outcomes were retrospectively evaluated in 127 patients with UGC. All patients had chemotherapy and 47 patients underwent gastrectomy. Patients were classified to three groups according to the treatment. RESULTS: Multivariate analysis showed that gastrectomy was in independent favorable prognosis factor (p<0.001) as well as performance status 0/1, differentiated type, absence of distant organ metastasis, and second line chemotherapy for UGC. Among the patients with gastrectomy, R0 resection was an independent prognostic factor (p=0.011). R0 resection was mainly achieved when there was a single non-curable factor and no distant organ metastasis (p=0.007 and p=0.024, respectively). CONCLUSION: Gastrectomy has an advantage in improving the survival in selected cases among UGC. If chemotherapy enables to control the non-curable factors, gastrectomy should be considered. PMID- 29599363 TI - Effects of omega-3 Fatty Acid Supplementation in Patients with Bile Duct or Pancreatic Cancer Undergoing Chemotherapy. AB - BACKGROUND/AIM: Omega-3 fatty acids may improve cancer cachexia, but only in patients with pancreatic and bile duct cancer. Patients with pancreatic cancer commonly suffer from exocrine pancreatic insufficiency, and the ingestion of digestive enzyme supplements may improve absorption. PATIENTS AND METHODS: Racol(r), an enteral nutrient formulated with omega-3 fatty acids, was administered to patients with unresectable pancreatic and bile duct cancer. The skeletal muscle mass and blood test data were taken pre-administration and at 4 and 8 weeks after. Patients with pancreatic cancer were given the digestive enzyme supplement LipaCreon(r) from the fifth week after the start of administration. RESULTS: In all 27 patients, skeletal muscle mass was significantly increased at both 4 and 8 weeks after the start of administration versus pre-administration (p=0.006, p=0.002, respectively). CONCLUSION: Omega-3 fatty acid supplementation in patients with unresectable pancreatic and bile duct cancer may improve cancer cachexia. PMID- 29599364 TI - Tumor Enhancement on Dynamic CT: A Predictive Factor for Recurrence After Nephrectomy in Localized T1 Clear Cell Renal Cell Carcinoma. AB - AIM: To investigate whether radiological parameters obtained on dynamic computed tomography (CT), especially those related to tumor enhancement, are predictive factors for recurrence after nephrectomy in localized stage T1 clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS: We retrospectively studied 88 patients with localized stage T1 ccRCC who underwent dynamic CT preoperatively. Seven patients had recurrent disease after surgery. Tumor attenuations were measured by placing a region of interest in the solid region. TApre and TAneph were defined as the tumor attenuation values of the pre-contrast and nephrographic phase, respectively. The correlations between disease-free survival and clinicopathological factors, including the radiological parameter TAneph - TApre (DeltaTAneph), were analyzed by Cox proportional hazards model or Kaplan Meier method with the log-rank test. RESULTS: Only DeltaTAneph was significantly and positively correlated with disease-free survival (p<0.05). Tumor size also tended to be negatively correlated with disease-free survival (p<0.1). The 5- and 10-year disease-free survival rates of the group with high DeltaTAneph (>=86 HU) were 97.4% and 97.4%, while those of the group with low DeltaTAneph (<86 HU) were 89.6% and 71.6%, respectively. CONCLUSION: Tumor enhancement in the nephrographic phase of CT was a predictive factor for recurrence after nephrectomy in patients with localized stage T1 ccRCC. PMID- 29599365 TI - Feasibility Study of Sequentially Alternating EGFR-TKIs and Chemotherapy for Patients with Non-small Cell Lung Cancer. AB - BACKGROUND/AIM: The purpose of this trial was to evaluate the feasibility and efficacy of alternating platinum-based doublet chemotherapy with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR mutant non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy naive patients with advanced NSCLC harboring an EGFR mutation were enrolled. All patients underwent induction chemotherapy by sequentially alternating pemetrexed/cisplatin/bevacizumab and EGFR-TKIs followed by maintenance therapy with pemetrexed/bevacizumab and EGFR-TKIs. The primary outcome was the completion rate of the induction therapy. RESULTS: Eighteen eligible patients were enrolled between May 2011 and March 2016. The completion rate of induction therapy was 72.2% (13/18). Unfortunately, one patient developed grade 4 acute renal injury, but no other serious complications concerning this protocol were observed. Furthermore, diarrhea, rashes, and hematological adverse effects were mild. CONCLUSION: The completion rate of induction therapy was promising. Alternating chemotherapy and EGFR-TKIs should be further investigated regarding feasibility and efficacy. PMID- 29599366 TI - Performance Status and Number of Metastatic Extra-cerebral Sites Predict Survival After Radiotherapy of Brain Metastases from Thyroid Cancer. AB - BACKGROUND/AIM: Patients with brain metastases from thyroid cancer are extremely rare. This study evaluated clinical factors for survival following whole-brain radiotherapy (WBRT) alone. PATIENTS AND METHODS: In six patients, the following factors were analyzed for survival: Regimen of WBRT (5*4 Gy vs. 10*3 Gy), gender, age (<=55 vs. >=56 years), Karnofsky performance score (KPS) (60% vs. 70-80%), number of brain lesions (2-3 vs. >=4) and number of extra-cranial metastatic sites (one vs. more than one). RESULTS: KPS 70-80% (p=0.036) and involvement of only one extra-cranial site (p=0.018) were associated with better survival on univariate analysis. On Cox regression analysis, KPS (p=0.14) and number of extra cranial sites (p=0.14) showed trends for association with survival. In patients with KPS 70-80% and only one extra-cranial site, 6-month survival was 100%, no patient with KPS 60% and more than one extra-cranial site survived to 6 months. CONCLUSION: KPS and number of involved extra-cranial metastatic sites were associated with survival and may be helpful for individualizing therapy in patients with brain metastases from thyroid cancer. PMID- 29599367 TI - Cost-effectiveness of Multiparametric MRI in 800 Men Submitted to Repeat Prostate Biopsy: Results of a Public Health Model. AB - BACKGROUND/AIM: To evaluate the cost-effectiveness of multiparametric magnetic imaging resonance (mpMRI) in men submitted to repeat saturation prostate biopsy (SPBx). MATERIALS AND METHODS: From January 2011 to June 2017, 800 men underwent repeat SPBx; the cost-effectiveness of mpMRI if used as a 'triage test' to avoid unnecessary repeat prostate biopsy was retrospectively calculated using the Italian Public National Health System Day Service. RESULTS: SPBx vs. MRI fusion targeted biopsy diagnosed 215 (89.5%) vs. 184 (76.6%) out of 240, respectively. The overall cost of the 800 prostate biopsies was 138,221 ?; the use of mpMRI as triage test would have spared 364/800 procedures, equivalent to 60,905 ? (44% of the entire cost), whilst missing 15/205 (7.3%) cases of clinically significant cancer. CONCLUSION: mpMRI used as a triage test could reduce the need for prostate biopsies by about 45%, thereby improving cost-effectiveness, however, patients should be informed of the false-negative rate associated with mpMRI. PMID- 29599368 TI - Metformin-associated Chemopreventive Effects on Recurrence After Hepatic Resection of Hepatocellular Carcinoma: From In Vitro to a Clinical Study. AB - BACKGROUND/AIM: We investigated metformin-induced cytotoxic effects in vitro and assessed the chemopreventive effects of metformin in patients undergoing hepatic resection (HR) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This study consisted of laboratory and clinical studies. RESULTS: In vitro study using HCC cell lines revealed noticeable cytotoxic effects of metformin, that were largely weaker than those of sorafenib. In the clinical study, no statistical differences were found in tumor recurrence or overall survival between metformin and control groups. In contrast, there was a non-significant difference in tumor recurrence between metformin and propensity score-matched control groups, but there was a significant difference in overall patient survival. Metformin administration was an independent risk factor for patient survival. CONCLUSION: In conclusion, our in vitro laboratory study demonstrated the presence of cytotoxic effects of metformin. Metformin administration was associated with reduced tumor recurrence and helped induce significant improvements in overall patient survival in patients who underwent HR for HCC. PMID- 29599369 TI - Phase I-II Study of Short-course Accelerated Radiotherapy (SHARON) for Palliation in Head and Neck Cancer. AB - AIM: To determine the maximum tolerated dose (MTD) of a short-course accelerated radiotherapy and its feasibility for symptomatic palliation of advanced head and neck cancer or head and neck metastases from any primary site. PATIENTS AND METHODS: A phase I trial in four dose-escalation steps was planned: total dose ranged between 14 and 20 Gy in a total of four fractions administered twice a day. The dose-limiting toxicity (DLT) was determined as grade 3 or more toxicity occurring during treatment. The MTD obtained was used to plan a phase II trial. RESULTS: A total of 48 patients were treated. In the phase I trial, the 20 Gy dose level was determined to be the MTD. In the phase II trial, the palliative response rate was 82.7%, with a median duration of palliation of 3 months. CONCLUSION: Short-course accelerated radiotherapy was well tolerated and effective for palliation. These findings may help design future prospective randomized studies. PMID- 29599370 TI - Predictive Factors for Local Control and Survival in Patients with Cancer of Unknown Primary (CUP) Irradiated for Cerebral Metastases. AB - BACKGROUND/AIM: To identify predictors of local control and survival after whole brain irradiation (WBI) for cerebral metastases from cancer of unknown primary (CUP). PATIENTS AND METHODS: In 140 patients receiving WBI alone or following resection, seven factors were investigated including treatment approach, WBI regimen, age, gender, Eastern Cooperative Oncology Group (ECOG) performance score, number of cerebral lesions and extra-cerebral metastases. RESULTS: On univariate analysis, resection plus WBI and boost (p=0.002), ECOG 0-1 (p<0.001) and a single lesion (p<0.001) were positively associated with local control. On Cox regression, ECOG-score remained significant (p=0.002). On univariate analysis of survival, surgery plus WBI and boost (p=0.009), ECOG 0-1 (p<0.001), a single lesion (p=0.024) and no extra-cerebral metastases (p<0.001) were associated with better outcomes. On Cox regression, ECOG-score (p<0.001) and extra-cerebral lesions (p<0.001) were significant. CONCLUSION: Significant predictors of local control and survival were identified that contribute to treatment personalization and design of prospective trials in patients with cerebral metastases from CUP. PMID- 29599371 TI - Usefulness of TAS-102 as Third-line Chemotherapy for Metastatic Colorectal Cancer. AB - BACKGROUND/AIM: The feasibility and oncological outcomes of treatment with TAS 102, that is recommended as third-line chemotherapy for patients with metastatic colorectal cancer (mCRC), remain unknown. PATIENTS AND METHODS: Between 2013 and 2015, seven patients (five males, two females) with mCRC who were administered TAS-102 as third-line chemotherapy at our Institution were retrospectively studied. During the same period, seven patients with mCRC with Kirsten rat sarcoma viral oncogene homolog (KRAS) wild-type primary lesions who were administered irinotecan with panitumumab comprised the control group. RESULTS: The duration of third-line chemotherapy in the TAS-102 group was 217.0 (range=136 337) days compared to 226.9 (range=122-335) days in the control group, with no significant difference in the duration of administration between the two groups. No significant difference in overall survival was identified between the two groups No serious adverse effects were encountered in either group. CONCLUSION: TAS-102 may be suitable as third-line chemotherapy for patients with mCRC. PMID- 29599372 TI - Interventions to Reduce Neurological Symptoms in Patients with GBM Receiving Radiotherapy: From Theory to Clinical Practice. AB - BACKGROUND: Patients affected by glioblastoma often develop cerebral oedema as a life-threatening complication. Although there is no approved pharmacological intervention, such cerebral oedema is usually treated with dexamethasone. Dexamethasone has been shown in experimental studies to reduce cerebral oedema with only few mineralocorticoid side-effects. The goal of our study was to examine its efficacy in reducing the emergence of neurological deficits during the Stupp protocol. PATIENTS AND METHODS: We studied a retrospective cohort of 459 patients, assigned in controlled groups: in group A, patients received radiochemotherapy followed by adjuvant chemotherapy; in group B, patients received an equivalent combined treatment with dexamethasone. RESULTS: The frequency of neurological symptoms was significantly lower in dexamethasone treated patients. CONCLUSION: Early diagnosis and prevention of cerebral oedema are important because functional consequences can be anticipated with an appropriate medical treatment. Thus, our study reveals that dexamethasone acts to prevent the appearance of neurological symptoms in patients with brain tumour. PMID- 29599373 TI - Clinicopathological Profiling of LC3B, an Autophagy Marker, and ESRRA (Estrogen related Receptor-alpha) in Muscle-invasive Bladder Cancer. AB - BACKGROUND/AIM: Microtubule-associated protein 1 light chain 3B (LC3B), an autophagy marker, has been used as a promising marker in various cancer types. However, the expression of LC3B in muscle-invasive bladder cancer (MIBC) and its prognostic significance have not been investigated. Recent studies pointed to the involvement of ESRRA in regulating autophagy via both transcriptional and post translational control. In the current study, prognostic importance of LC3B and ESRRA in MIBC was investigated. PATIENTS AND METHODS: We immunohistochemically studied the expression of LC3B and ESRRA in 56 MIBC samples. RESULTS: LC3B was stained high in 16 patients (28.6%) and low or negative in 40 patients (71.4%). ESRRA expression was high for 20 patients (35.7%) and low for 36 patients (64.3%). Both LC3B (p=0.003) and ESRRA (p=0.026) expression correlated significantly with disease-free survival rates. Double-positive LC3B and ESRRA correlated with poor overall survival (p=0.007) and disease-free survival (p=0.001) in MIBC patients. CONCLUSION: LC3B and ESRRA might be a useful prognostic factor in patients with MIBC. The co-expression of LC3B and ESRRA might be a prognostic and therapeutic target for patients with bladder cancer. PMID- 29599374 TI - Natural History of Squamous Intraepithelial Lesions in Pregnancy and Mode of Delivery. AB - BACKGROUND: Numerous studies have addressed the impact of mode of delivery on the natural history of squamous intraepithelial lesions (SIL) in pregnant women. However, the literature is still contradictory. PATIENTS AND METHODS: In the course of a retrospective analysis, data of 63 pregnant women with abnormal cervical smears who were referred to our Outpatient Department for pre-invasive lesions of the cervix were analyzed. The study was conducted at the General Hospital in Vienna, Austria, between 2010 and 2015. Data collection included demographics, delivery route and diagnostic results of cervical lesions by cytology, colposcopy, human papilloma virus (HPV) testing, histological report of punch biopsy and, if applicable, cone biopsy. RESULTS: Among 63 women who met the inclusion criteria, 40 (63%) delivered vaginally and 23 (37%) underwent caesarean section. Postpartum regression of cervical dysplasia was documented in 15 women delivering vaginally and in 10 who had a caesarean section (p=0.641). Among those women who delivered vaginally, three had progression and in 22 women the lesions persisted postpartum. In the group of women with caesarean section, one had progression and the lesions of 12 women persisted after delivery. No woman had progression to invasive disease. CONCLUSION: The mode of delivery does not significantly influence the natural history of cervical dysplastic lesions in pregnant women. The numbers of spontaneous regressions to normal cervical cytology during pregnancy were similar in both groups. PMID- 29599375 TI - Enterocolitis in Patients with Cancer Treated with Docetaxel. AB - BACKGROUND: Enterocolitis is a rare, but serious gastrointestinal complication associated with docetaxel-based chemotherapy in patients with cancer. The incidence, clinical presentation and outcome of enterocolitis in patients with cancer treated with docetaxel-based chemotherapy was assessed in this study Patients and Methods: All patients treated with docetaxel for cancer between January 2010 and December 2014 at the University Hospital of Besancon were identified and their medical records reviewed. RESULTS: During this period, 1,227 patients received docetaxel chemotherapy and gastrointestinal events occurred in 381 (31.1%) patients. In multivariate analysis, a higher risk of gastrointestinal events was associated with a higher dose of docetaxel (>=75 mg/m2) (odds ratio(OR)=46.2; 95% confidence interval(CI)=5.4-397.0, p=0.0005) and the first cycle of docetaxel (OR=4.2; 95% CI=1.8-10.1, p=0.001). Among the 381 patients with gastrointestinal events, grade 3/4 neutropenia, diarrhea, febrile neutropenia, mucositis, nausea/vomiting, and rectal bleeding were diagnosed in 65 (17.1%), 51 (13.4%), 37 (9.7%); 12 (3.1%), seven (1.8%) and three (0.8%) patients, respectively; 54 patients (14.2%) were hospitalized. Computed tomographic scan was performed for 39 patients (10.2%). Twenty-seven patients presented radiological signs of enterocolitis. Three deaths (0.8%) related to enterocolitis were recorded. Docetaxel was resumed in 261 patients (68.5%) and the dose was reduced in 89 patients (23.4%). Docetaxel was discontinued in 120 patients (31.5%). CONCLUSION: Gastrointestinal events in patients treated with docetaxel may be a potential sign of fatal enterocolitis and require particular attention. Dose reduction at the first cycle may reduce the risk of such events. PMID- 29599376 TI - Effectiveness and Safety of Tissue Expander for Adjuvant Helical Tomotherapy in Curatively Resected Retroperitoneal Sarcoma. AB - BACKGROUND/AIM: We investigated the effectiveness and safety of using a tissue expander (TE) for adjuvant helical tomotherapy (HT) for curatively resected retroperitoneal sarcoma (RPS). MATERIALS AND METHODS: This study was conducted with 60 RPS patients who underwent curative resection with or without TE insertion followed by HT from June 2009 to December 2016. Among the patients, TE was inserted in 37 (61.7%). The quality of TE insertion was evaluated. Median follow-up after surgery was 19.4 months (range=4.5-93.2 months). RESULTS: A higher biologically-equivalent dose (alpha/beta=10) was used with patients who had TE insertion (median, 72.0 gray [Gy] vs. 67.1 Gy, p=0.02). The quality of TE insertion was excellent in 18 patients (48.6%), good in 10 (27.0%), fair in seven (18.9%), and poor in two (5.4%). Toxicity was not significantly different according to TE insertion. Local recurrence-free survival (LRFS) was 78.2%, and overall survival was 95.6% at 3 years. TE insertion was not a significant factor for LRFS (91.1% in TE vs. 62.9% in non-TE group at 3 years, p=0.62). In the subgroup of patients with R1 or unknown tumor margin status, however, LRFS was marginally higher in the TE insertion group (100.0% in TE vs. 62.9% non-TE group at 3 years, p=0.05). CONCLUSION: HT with TE insertion as adjuvant RT for curatively resected RPS was feasible with acceptable toxicity. In the patients with R1 or unknown tumor margin status, LRFS was marginally higher in the TE insertion group after HT. PMID- 29599377 TI - Clinicopathological Analysis of Ultrasound-guided Vacuum-assisted Breast Biopsy for the Diagnosis and Treatment of Breast Disease. AB - BACKGROUND/AIM: To evaluate the usefulness and safety of vacuum-assisted breast biopsy (VABB) for breast lesion diagnosis and treatment. PATIENTS AND METHODS: Clinical and histopathological data of 8,748 patients, who underwent 11,221 VABB procedures were analyzed. RESULTS: Most patients (58.2%) were <40 years old. Most lesions (39.6%) were 0.6-1.0 cm in diameter while 3.2% were >=3.0 cm; fibroadenomas were the most common (46.6%). Eight (14% of 57) cases of atypical ductal hyperplasia were underestimated. The positive predictive values (PPVs) of breast imaging reporting and data system (BI-RADS) ultrasound category were 0.6%, 3.4%, 34.8%, 66.2%, and 93.8% for category 3, 4a, 4b, 4c, and 5 lesions, respectively. The mean number of core specimens was 9.5+/-8.8; the mean procedure time was 3.4+/-2.7 min. No residual lesions were found in 94.4% of the 7,480 patients. CONCLUSION: VABB could replace ultrasound-guided core biopsy and surgical excisional biopsy for the diagnosis of breast disease and the treatment of benign breast lesions. PMID- 29599378 TI - Effects of supplemental oxygen therapy in patients with suspected acute myocardial infarction: a meta-analysis of randomised clinical trials. AB - BACKGROUND: Although oxygen therapy has been used for over a century in the management of patients with suspected acute myocardial infarction (AMI), recent studies have raised concerns around the efficacy and safety of supplemental oxygen in normoxaemic patients. OBJECTIVE: To synthesise the evidence from randomised controlled trials (RCTs) that investigated the effects of supplemental oxygen therapy compared with room air in patients with suspected or confirmed AMI. METHODS: For this aggregate data meta-analysis, multiple databases were searched from inception to 30 September 2017. RCTs with any length of follow-up and any outcome measure were included if they studied the use of supplemental O2 therapy administered by any device at normal pressure compared with room air. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, an investigator assessed all the included studies and extracted the data. Outcomes of interests included mortality, troponin levels, infarct size, pain and hypoxaemia. RESULTS: Eight RCTs with a total of 7998 participants (3982 and 4002 patients in O2 and air groups, respectively) were identified and pooled. In-hospital and 30-day death occurred in 135 and 149 patients, respectively. Oxygen therapy did not reduce the risk of in-hospital (OR, 1.11 (95% CI 0.69 to 1.77)) or 30-day mortality (OR, 1.09 (95% CI 0.80 to 1.50)) in patients with suspected AMI, and the results remained similar in the subgroup of patients with confirmed AMI. The infarct size (based on cardiac MRI) in a subgroup of patients was not different between groups with and without O2 therapy. O2 therapy reduced the risk of hypoxaemia (OR, 0.29 (95% CI 0.17 to 0.47)). CONCLUSION: Although supplemental O2 therapy is commonly used, it was not associated with important clinical benefits. These findings from eight RCTs support departing from the usual practice of administering oxygen in normoxaemic patients. PMID- 29599380 TI - Basilic vein haemangioma: an unusual differential diagnosis for cubital fossa mass. AB - Subcutaneous masses along the cubital fossa can be a diagnostic dilemma. Most patients are asymptomatic and usually present for a cosmetic reason. Diagnosis can be confirmed by radiological findings and histopathology. We present a case report of a similar mass that turned out to be a haemangioma arising from the basilic vein with brief review of literature. PMID- 29599379 TI - Comparison of general anaesthesia and non-general anaesthesia approach in transfemoral transcatheter aortic valve implantation. AB - OBJECTIVE: Performing transfemoral transcatheter aortic valve implantation (TAVI) without general anaesthesia (GA) has been increasingly adopted. We sought to study the impact of GA and non-GA approaches on procedural outcome and 30-day and 1-year mortality in transfemoral TAVI. METHODS: The UK TAVI registry holds information for every TAVI procedure in the UK. We analysed the data for patients implanted during 2013-2014 using either an Edwards Sapien or a Medtronic CoreValve prosthesis. Propensity score-matching analysis was performed to adjust for confounding factors. RESULTS: 2243 patients were studied (aged 81.4+/-7.5 years, 1195 males). 1816 (81%) underwent TAVI with GA and 427 (19%) without GA. Transoesophageal echocardiography (TOE) was used in 92.3% of GA and 12.4% of non GA cases (p<0.001). There was no significant difference in the rate of successful valve deployment (GA 97.2% vs non-GA 95.7%, p=0.104) and in the incidence of more than mild aortic regurgitation (AR) at the end of the procedure (GA 5.6% vs non GA 7.0%, p=0.295). However, procedure time was longer (131+/-60 vs 121+/-60mins, p=0.002) and length of stay was greater (8.0+/-13.5 vs 5.7+/-5.5 days, p<0.001) for GA cases. 30-day and 1-year mortality rates did not differ between the GA and non-GA cases. After propensity matching, these results remained unchanged. A second propensity analysis (adjusted for mode of anaesthesia) did not show an association between use of TOE and rate of successful valve deployment or frequency of significant AR. Neither was TOE associated with a longer procedural time or greater length of stay. CONCLUSION: Procedure outcome, and 30-day and 1 year mortality are not influenced by mode of anaesthesia. However, GA is associated with longer procedure duration and greater length of stay. PMID- 29599381 TI - Secondary mania following cancer chemotherapy with capecitabine. AB - Mania-like states occurring due to neurological, metabolic or toxic conditions, without a primary mood disorder have been reported in scientific literature as secondary mania. A major clinical problem in such situations often stems from the difficulty to understand if the mood disturbance is indeed secondary to an organic cause or a coincidental primary mood disorder. Chemotherapy regimens have been associated with multiple psychiatric complications, including psychosis, mania and anxiety. Capecitabine is implicated to be associated with encephalopathy whose clinical presentation often mimics that of psychosis. However, presentations with mania have not been reported until with the capecitabine and oxaliplatin combination chemotherapy regimen. In this report, we describe a case of secondary mania in a patient suffering from carcinoma colon on treatment with chemotherapy regimen of capecitabine and oxaliplatin. PMID- 29599382 TI - Large intra-abdominal seminoma in a left undescended testicle complicated by torsion. AB - A 39-year-old man presented with a 2-day history of worsening constant, dull diffuse lower abdominal pain with associated constipation and known history of left undescended testicle. He was evaluated at an outside hospital where a non contrasted CT scan revealed a 20 cm well-circumscribed soft tissue mass within the pelvis.He was referred and further imaging revealed a 12 cm heterogeneous mass with foci of air that appeared to be contiguous with the left spermatic cord. This constellation of findings could represent torsion of undescended left testicle with infarction or underlying malignancy. Tumour markers were only significant for elevated lactate dehydrogenase of 1445. A subsequent ultrasound guided biopsy of the mass demonstrated seminoma.Surgical resection revealed a large intra-abdominal mass emanating from the left spermatic cord with 270 degrees of torsion. There appeared to be a left atrophic remnant testicle at the base of the mass with final pathology confirming the diagnosis of classic seminoma. PMID- 29599383 TI - Ethics of a therapeutic trial: addressing limitations of an active intervention in optic nerve lymphoma. AB - We report a unique case of optic nerve lymphoma after completion of chemotherapy for non-Hodgkin's lymphoma. The uncommon nature of presentation, our therapeutic dilemma and the further course of treatment are reported. In cases with extremely poor prognosis, unnecessary treatment puts additional strain both financially and psychologically on the patients and their family. Therapeutic focus should be on hospice care and family counselling. The decision to not treat is a crucial component of cancer management; however, the ethics of this decision are yet to be suitably addressed by the literature. PMID- 29599384 TI - Pneumatosis intestinalis in a preterm infant: should we treat all intestinal pneumatosis as necrotising enterocolitis? AB - Gastric pneumatosisis a very rare site of pneumatosis intestinalis (PI), and we report this finding in a preterm female infant with cyanotic congenital heart disease. The infant was stable initially on nasal intermittent mandatory ventilation; however, torrential pulmonary flow through a large patent ductus arteriosus prompted closure using oral ibuprofen. After an episode of haematochezia, she developed PI, affecting mainly the gastric wall and small intestine with portal venous gas. Her bowel movements were regular, with no abdominal distension or significant gastric aspirates. She was haemodynamically stable with negative infective markers. Management consisted of endotracheal intubation and ventilation, gastric decompression and broad-spectrum antibiotics. Both the gastric and intestinal pneumatosis resolved within 24 hours and she made an uneventful recovery. If PI is not due to necrotising enterocolitis, enteral nutrition can be initiated early and prolonged course of broad-spectrum antibiotics could have been avoided. PMID- 29599385 TI - Prevalence and sociodemographic determinants of adult obesity: a large representative household survey in a resource-constrained African setting with double burden of undernutrition and overnutrition. AB - BACKGROUND: The obesity epidemic has continued to spread across the globe involving even poor nations of the world. METHOD: Household population survey of adults aged 20-60 years. Multistage stratified cluster randomised sampling involving both urban and rural statewide representative population samples. Anthropometric measurements were taken using standard methods. Prevalences were weighted and multinomial regression analyses were done. RESULTS: A total of 6628 individuals from 2843 households were surveyed. The weighted overall prevalence for underweight was 9.1% (95% CI 8.1 to 10.1), 65.1% (95% CI 63.6 to 66.6) for normal weight, 19.0% (95% CI 17.8 to 20.3) for overweight and 6.8% (95% CI 6.0 to 7.5) for obese. Men were less likely to be overweight (adjusted OR (AOR) 0.79; 95% CI 0.68 to 0.92) and obese (AOR 0.24; 95% CI 0.19 to 0.31) than women. Urban residents were more likely to be overweight (AOR 1.42; 95% CI 1.18 to 1.71) and obese (AOR 2.09; 95% CI 1.58 to 2.76) than rural residents. Each additional 1 year increase in age increased the risk of overweight by 1.012 (AOR 1.012; 95% CI 1.005 to 1.018) and that of obesity by 1.03 (AOR 1.03; 95% CI 1.02 to 1.04). The low-income class was less likely to be overweight (AOR 0.694; 95% CI 0.507 to 0.951) and obese (AOR 0.44; 95% CI 0.28 to 0.67). CONCLUSION: The prevalence of obesity and overweight in Enugu Nigeria is high and fast approaching that of underweight. Women, urban dwellers, older adults and high-income earners are at higher risk for obesity and overweight. The study provides robust information for public health policies towards the prevention of obesity in Nigeria. PMID- 29599386 TI - Association between psychological distress and mortality: the case of Israel. AB - BACKGROUND: Previous studies have demonstrated the association between psychological distress (measured by the 12-item General Health Questionnaire, GHQ 12) and risks of all-cause mortality and deaths from cardiovascular, cancer and other causes. We hypothesised that in the Israeli population permanently exposed to war/terror stressors, this relationship is absent. METHODS: We performed an analysis of data from participants in the Israel National Health Survey conducted in 2003-2004, who died during the follow-up decade. Subjects were assigned to groups based on GHQ-12 score: 0-10 (asymptomatic), 11-14 (subclinically symptomatic), 15-19 (symptomatic) and 20-36 (highly symptomatic). Data were weighted to the total population. RESULTS: We analysed data from 4843 individuals, median age 40.5 (IQR 28-54); 473 participants died during the follow up. We found a significant increase in total mortality, cardiovascular and other causes of mortality (but not cancer deaths) with increase in GHQ-12 score (P for linear trend of ungrouped GHQ scores <0.0001, 0.0015 and <0.0001, respectively). The age-sex-adjusted HR for the highest GHQ-12 compared with the lowest asymptomatic category was 2.1 (95% CI 1.6 to 2.7) for all-cause deaths, 2.3 (95% CI 1.3 to 4.1) for cardiovascular disease deaths and 2.7 (95% CI 1.9 to 3.9) for other deaths. The HR remained significant after adjustment for education, smoking, alcohol consumption and diabetes. The HR even increased after excluding participants with baseline cardiovascular diseases and cancer. CONCLUSION: Contrary to our hypothesis, psychological distress was associated with all-cause and cardiovascular but not cancer mortality. The absence of reverse causality provides evidence for the direct deleterious effects of psychological distress on mortality outcomes. PMID- 29599387 TI - Clinical and sexual risk correlates of Mycoplasma genitalium in urban pregnant and non-pregnant young women: cross-sectional outcomes using the baseline data from the Women's BioHealth Study. AB - OBJECTIVE: Research exploring the clinical and sexual risk correlates is essential to define universal standards for screening and management for Mycoplasma genitalium (MG). The objective of this study is to determine the baseline prevalence of MG and associated clinical risks using cross-sectional data. METHODS: Adolescent and young adult women 13-29 years were recruited during clinical visits during which biological specimens were collected for Neisseriagonorrhoeae (NG) and Chlamydia trachomatis (CT) testing to provide vaginal specimens for MG and Trichomonasvaginalis (TV) testing. Demographic, clinical and sexual risk data were collected after obtaining written consent. MG was tested using the Hologic Gen-Probe transcription-mediated amplification-MG analyte-specific reagent assay and TV by the Aptima TV assay. Bivariate analyses were used to evaluate differences in MG prevalence based on pregnancy status, demographic factors, clinical symptoms, concurrent STI and sexual risk behaviour quiz score (maximum score=10). RESULTS: 483 patients with a mean age of 22.4 years (SD 3.6) were enrolled. Most participants were not pregnant (66%) and asymptomatic (59%). MG was the most common STI (MG 16%, TV 9%, CT 8%, NG 1%). Neither pregnancy nor symptoms were predictive of STI positivity. Thirty-five percent of non-pregnant and 45% of pregnant adolescents <=19 years were positive for any STI. Participants with MG were 3.4 times more likely to be co-infected with other STIs compared with those with other STIs (OR 3.4, 95% CI 1.17 to 10.3, P=0.021). Mean risk quiz scores for STI positive women were six points higher than those who were STI negative (beta=0.63, 95% CI 0.36 to 0.90, P<0.001). There were no differences in risk scores for MG-positive participants compared with other STI positivity. CONCLUSION: MG infection was common, associated with STI co infection and often asymptomatic, and pregnancy status did not confer protection.

PMID- 29599389 TI - Dual Coding of Frequency Modulation in the Ventral Cochlear Nucleus. AB - Frequency modulation (FM) is a common acoustic feature of natural sounds and is known to play a role in robust sound source recognition. Auditory neurons show precise stimulus-synchronized discharge patterns that may be used for the representation of low-rate FM. However, it remains unclear whether this representation is based on synchronization to slow temporal envelope (ENV) cues resulting from cochlear filtering or phase locking to faster temporal fine structure (TFS) cues. To investigate the plausibility of those encoding schemes, single units of the ventral cochlear nucleus of guinea pigs of either sex were recorded in response to sine FM tones centered at the unit's best frequency (BF). The results show that, in contrast to high-BF units, for modulation depths within the receptive field, low-BF units (<4 kHz) demonstrate good phase locking to TFS. For modulation depths extending beyond the receptive field, the discharge patterns follow the ENV and fluctuate at the modulation rate. The receptive field proved to be a good predictor of the ENV responses for most primary-like and chopper units. The current in vivo data also reveal a high level of diversity in responses across unit types. TFS cues are mainly conveyed by low-frequency and primary-like units and ENV cues by chopper and onset units. The diversity of responses exhibited by cochlear nucleus neurons provides a neural basis for a dual-coding scheme of FM in the brainstem based on both ENV and TFS cues.SIGNIFICANCE STATEMENT Natural sounds, including speech, convey informative temporal modulations in frequency. Understanding how the auditory system represents those frequency modulations (FM) has important implications as robust sound source recognition depends crucially on the reception of low-rate FM cues. Here, we recorded 115 single-unit responses from the ventral cochlear nucleus in response to FM and provide the first physiological evidence of a dual-coding mechanism of FM via synchronization to temporal envelope cues and phase locking to temporal fine structure cues. We also demonstrate a diversity of neural responses with different coding specializations. These results support the dual coding scheme proposed by psychophysicists to account for FM sensitivity in humans and provide new insights on how this might be implemented in the early stages of the auditory pathway. PMID- 29599390 TI - Use of neuropsychological tests for the diagnosis of dementia: a survey of Italian memory clinics. AB - AIM: Providing an overview of the neuropsychological tests used in Italian memory clinics (defined as Centers for Cognitive Disorders and Dementias-CCDD in Italy) for the diagnosis of cognitive disorders and dementias. METHODS: A total of 501 CCDD, out of all 536 active CCDD, were surveyed between February 2014 and August 2015 to verify the characteristics of the centres who performed a comprehensive neuropsychological assessment (NPA), defined as the administration of at least one test for verbal and visual episodic memory, attention, constructional praxis, verbal fluency and executive functions (minimum core tests-MCTs), as part of the diagnostic process. RESULTS: A total of 45.7% of Italian CCDD performed a comprehensive MCT as part of the diagnostic process. The logistic regression model showed that the probability of including at least one psychologist in the team was higher in the CCDD that reported using a comprehensive NPA (OR 4.55; 95% CI 2.92 to 7.1), that CCDD in Southern Italy had a lower probability of using an MCT (OR 0.56; 95% CI 0.35 to 0.89) and that the use of an MCT was higher in university/Institute for Scientific Research and Healthcare CCDD (OR 10.97; 95% CI 3.85 to 31.25). CONCLUSION: Almost half of the CCDD administered a set of MCTs; while the remaining centres only performed few tests or screening procedures. The neuropsychological tests used in Italian CCDD were comparable with those used in other European countries. Performing a comprehensive NPA remains the best way to assess and monitor cognitive deficits over time, thus further debate on the current status of NPAs in clinical practice is needed. PMID- 29599391 TI - DupuytrEn Treatment EffeCtiveness Trial (DETECT): a protocol for prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of collagenase clostridium histolyticum, percutaneous needle fasciotomy and limited fasciectomy as short term and long-term treatment strategies in Dupuytren's contracture. AB - INTRODUCTION: Dupuytren's contracture (DC) is a chronic fibroproliferative disorder of the palmar fascia which leads to flexion contracture in one or more fingers. There is no definitive cure for DC, and treatment aims at relieving symptoms by releasing the contracture using percutaneous or operative techniques. METHODS AND ANALYSIS: We planned a prospective, randomised, controlled, outcome assessor-blinded, three-armed parallel 1:1:1, multicentre trial comparing the effectiveness and cost of (1) collagenase clostridium histolyticum injection followed by limited fasciectomy in non-responsive cases, (2) percutaneous needle fasciotomy followed by limited fasciectomy in non-responsive cases and (3) primary limited fasciectomy during short-term and long-term follow-up for Tubiana I-III stages DC. We will recruit participants from seven national centres in Finland. Primary outcome is the rate of success in the treatment arm at 5 years after recruitment. Success is a composite outcome comprising (1) at least 50% contracture release from the date of recruitment and (2) participants in a patient-accepted symptom state (PASS). Secondary outcomes are (1) angle of contracture, (2) quick disabilities of the arm, a shoulder and hand outcome measure (QuickDASH), (3) perceived hand function, (4) EQ-5D-3L, (5) rate of major adverse events, (6) patient's trust of the treatment, (7) global rating, (8) rate of PASS, (9) rate of minimal clinically important improvement, (10) expenses, (11) progression of disease, (12) progression-free survival, (13) favoured treatment modality, (14) patients achieving full contracture release and >50% improvement and (15) patient satisfaction with the treatment effect. Predictive factors for achieving the PASS will also be analysed. ETHICS AND DISSEMINATION: The protocol was approved by the Tampere University Hospital Institutional Review Board and Finnish Medicine Agency. The study will be performed according to the principles of good clinical practice. The results of the trial will be disseminated as published articles in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03192020; Pre-results. PMID- 29599392 TI - Prevalence and distribution of hypertension and related risk factors in Jilin Province, China 2015: a cross-sectional study. AB - OBJECTIVE: This study aimed to investigate the prevalence and distribution of hypertension and its related factors in Jilin province, China. DESIGN: A cross sectional study in four cities and four rural counties in Jilin as part of a national Chinese study. PARTICIPANTS AND SETTING: A total of 15 206 participants who were >=15 years old and were selected using a stratified multistage random sampling method. MAIN OUTCOME MEASURES: The prevalence of hypertension. RESULTS: The prevalence of hypertension in Jilin province was 24.7%. Moreover, the prevalence of hypertension increased with age in both sexes, and was higher in men than in women. The modifiable factors that were associated with hypertension were body mass index, smoking and alcohol drinking. The risk factors identified are similar to those in southern China, except smoking, which has no association with hypertension prevalence in the South. CONCLUSIONS: Age, sex, body mass index, smoking and alcohol drinking were risk factors of hypertension. Control of these related risk factors, especially smoking, may be helpful in the treatment and management of hypertension in Jilin province.

AB - OBJECTIVES: The aims of the present study were to establish the prevalence of stroke, and to explore the association between stroke prevalence and sociodemographic and health factors, disability, cognitive functioning and care needs among older adult residents in Singapore. SETTING: Data were drawn from the Well-being of the Singapore Elderly study-a cross-sectional epidemiological survey conducted from 2012 to 2013 on older adults living in Singapore. PARTICIPANTS: Participants were Singapore residents (citizens and permanent residents) 60 years and above who were living in Singapore during the survey period . Older adult residents who were institutionalised were also included in this study. Those who were not living in Singapore or who were not contactable were excluded from the study. The response rate was 65.6 % (2565/3913). A total population sample of 2562 participants completed the survey. Participants comprised 43.6% males and 56.4% females. The sample comprised 39.4% Chinese, 29.1% Malay, 30.1% Indian and 1.4% other ethnicities . PRIMARY AND SECONDARY OUTCOME MEASURES: History of stroke, along with other health and mental health conditions, disability and cognitive functioning, were determined by self-report. RESULTS: Weighted stroke prevalence was 7.6% among older adults aged 60 and above. At a multivariate level, Malay ethnicity (OR 0.41, p=0.012, 95% CI 0.20 to 0.82), hypertension (OR 4.58, p=0.001, 95% CI 1.84 to 11.40), heart trouble (OR 2.45, p=0.006, 95% CI 1.30 to 4.63), diabetes (OR 2.60, p=0.001, 95% CI 1.49 to 4.53) and dementia (OR 3.57, p=0.002, 95% CI 1.57 to 8.12) were associated with stroke prevalence. CONCLUSIONS: Several findings of this study were consistent with previous reports. Given that Singapore's population is ageing rapidly, our findings may indicate the need to review existing support services for stroke survivors and their caregivers. Future research could investigate the association between various sociodemographic and health conditions and stroke prevalence to confirm some of the findings of this study. PMID- 29599394 TI - Improving quality and safety in nursing homes and home care: the study protocol of a mixed-methods research design to implement a leadership intervention. AB - INTRODUCTION: Nursing homes and home care face challenges across different countries as people are living longer, often with chronic conditions. There is a lack of knowledge regarding implementation and impact of quality and safety interventions as most research evidence so far is generated in hospitals. Additionally, there is a lack of effective leadership tools for quality and safety improvement work in this context. METHODS AND ANALYSIS: The aim of the 'Improving Quality and Safety in Primary Care-Implementing a Leadership Intervention in Nursing Homes and Homecare' (SAFE-LEAD) study is to develop and evaluate a research-based leadership guide for managers to increase quality and safety competence. The project applies a mixed-methods design and explores the implications of the leadership guide on managers' and staffs' knowledge, attitudes and practices. Four nursing homes and four home care services from different Norwegian municipalities will participate in the intervention. Surveys, process evaluation (interviews, observations) and document analyses will be conducted to evaluate the implementation and impact of the leadership intervention. A comparative study of Norway and the Netherlands will establish knowledge of the context dependency of the intervention. ETHICS AND DISSEMINATION: The study is approved by the Norwegian Centre for Research Data (2017/52324 and 54855). The results will be disseminated through scientific articles, two PhD dissertations, an anthology, presentations at national and international conferences, and in social media, newsletters and in the press. The results will generate knowledge to inform leadership practices in nursing homes and home care. Moreover, the study will build new theory on leadership interventions and the role of contextual factors in nursing homes and home care. PMID- 29599397 TI - Pharmacology, Part 1: Introduction to Pharmacology and Pharmacodynamics. AB - There is an emerging need for greater understanding of pharmacology principles among technical staff. Indeed, the responsibility of dose preparation and administration, under any level of supervision, demands a foundational understanding of pharmacology. This is true for radiopharmaceuticals, contrast media, and pharmaceutical interventions or adjunctive medications. Regulation around the same might suggest a need to embed pharmacology theory in undergraduate education programs, and there is a need to disseminate that same foundational understanding to practicing clinicians. Moreover, pharmacology foundations can provide a key understanding of the principles that underpin quantitative techniques (e.g., pharmacokinetics). This article is the first in a series that aims to enhance the understanding of pharmacologic principles relevant to nuclear medicine. This article will deal with the introductory concepts, terminology, and principles that underpin the concepts to be discussed in the remainder of the series. The second article will build on the pharmacodynamic principles examined in this article with a treatment of pharmacokinetics. Article 3 will outline pharmacology relevant to pharmaceutical interventions and adjunctive medications used in general nuclear medicine, article 4 will cover pharmacology relevant to pharmaceutical interventions and adjunctive medications used in nuclear cardiology, and article 5 will discuss the pharmacology related to contrast media associated with CT and MRI. The final article (6) in the series will examine the pharmacology of drugs associated with the crash cart/emergency trolley. PMID- 29599396 TI - Diagnostic concordance of reporting lymphovascular invasion in breast cancer. AB - AIMS: This study aims to assess the diagnostic agreement of lymphovascular invasion (LVI) in invasive breast cancer (BC). METHODS: Data on LVI were collected from the UK National Health Service Breast Screening Programme pathology external quality assurance scheme database. 101 BCs assessed over a 10 year period (2004-2014) were included. Cases were scored by an average of 600 pathologists. Three H&E stained slides from each case were reviewed by three pathologists and additional variables were evaluated. RESULTS: In the whole series, the overall kappa value was 0.4 (range 0.26-0.53). On review, LVI was detected in all three slides in 20 cases (20%), in two slides in 12 cases and in one of the three slides in 9 cases and was not seen in 60 cases. For concordance analysis, the first and last groups were used to represent cases with definite (LVI+) and absent LVI (LVI-), respectively. In the LVI+group (n=20), the level of agreement ranged from 0.54 to 0.99 (median 0.86). In the LVI- group (n=60), the level of agreement ranged from 0.52 to 1.00 (median 0.93), with 44% of cases showing interobserver concordance of >95%. There was a correlation between increasing number of involved lymphovascular spaces in the section and higher LVI reporting concordance. Some degree of retraction/fixation artefacts was observed in 35% of cases; this was associated with a lower concordance rate. CONCLUSIONS: The concordance of reporting LVI is variable. Cases without LVI and those with multiple involved vessels are likely to have the highest concordance and the highest detection rates. PMID- 29599395 TI - Exploring factors impacting early childhood health among Aboriginal and Torres Strait Islander families and communities: protocol for a population-based cohort study using data linkage (the 'Defying the Odds' study). AB - INTRODUCTION: Empirical evidence on family and community risk and protective factors influencing the comparatively high rates of potentially preventable hospitalisations and deaths among Aboriginal and Torres Strait Islander infants and children is limited. As is evidence on geographical variation in these risks. The 'Defying the Odds' study aims to explore the impact of perinatal outcomes, maternal social and health outcomes and level of culturally secure service availability on the health outcomes of Western Australian (WA) Aboriginal infants and children aged 0-5 years. METHODS AND ANALYSIS: The study combines a retrospective cohort study that uses state-wide linked health and administrative data from 12 data sources for multiple generations within Aboriginal families in WA, with specifically collected survey data from health and social services supporting Aboriginal families in regions of WA. Data sources include perinatal/birth registration, hospital, emergency department, mental health services, drug and alcohol service use, mortality, infectious disease notifications, and child protection and family services. Multilevel regression models will be used to examine the intensity of admissions and presentations, mortality, intensity of long stays and morbidity-free survival (no admissions) for Aboriginal children born in WA in 2000-2013. Relationships between maternal (and grand-maternal) health and social factors and child health outcomes will be quantified. Community-level variation in outcomes for Aboriginal children and factors contributing to this variation will be examined, including the availability of culturally secure services. Online surveys were sent to staff members at relevant services to explore the scope, reach and cultural security of services available to support Aboriginal families across selected regions of WA. ETHICS AND DISSEMINATION: Ethics approvals have been granted for the study. Interpretation and dissemination are guided by the study team's Aboriginal leadership and reference groups. Dissemination will be through direct feedback and reports to health services in the study and via scientific publications and policy recommendations. PMID- 29599398 TI - Role of an Intensity-Transformation Function in Enhancement of Bone Scintigraphy Images. AB - Bone scintigraphy images might exceed the dynamic range (the ratio between the highest and the lowest displayable brightness) of the monitor. In such a case, a high-intensity area accompanied by loss of detail in other structures in the displayed image make the clinical interpretation challenging. We have investigated the role of an intensity-transformation (IT) function in enhancement of these types of images. Methods: Forty high-dynamic-range bone scintigraphy images were processed using an IT function. The IT function has 2 parameters: threshold and slope. With the threshold kept equal to the mean count of the image, the slope was varied from 1 to 20. A software program developed in-house was used to process the images. Twenty output images corresponding to one input image were visually inspected by 2 experienced nuclear medicine physicians to select images of diagnostic quality, and from their selection was determined the standardized slope that produced the maximum number of diagnostic images. The 2 physicians also scored the quality of the input and output images (at the standardized slope) on a scale of 1-5. The Student t test was used to determine the significance of differences in mean score between the input and output images at an alpha significance level of 0.05. Results: Application of the IT function with standardized parameters significantly improved the quality of high-dynamic range bone scintigraphy images (P < 0.001, with alpha = 0.05). A slope of 8 maximized the number of diagnostic images. Conclusion: The IT function has a significant role in enhancing high-dynamic-range bone scintigraphy images. PMID- 29599399 TI - Molecular Breast Imaging: Administered Activity Does Not Require Adjustment Based on Patient Size. AB - At our institution, molecular breast imaging (MBI) is performed with 300 MBq of 99mTc-sestamibi for all patients. For some nuclear medicine procedures, administered activity or imaging time is increased for patients of larger size to obtain adequate counts. Our objective was to assess whether uptake of 99mTc sestamibi in the breast is influenced by patient size. Methods: Records from patients who underwent a clinical MBI examination between July and November 2016 were reviewed. Those in whom our standard injection and preparation techniques were followed were included in the analysis. Patients were injected with approximately 300 MBq of 99mTc-sestamibi. Residual activity was measured to allow calculation of exact administered activity for each patient. Breast images were acquired at 10 min/view using a dual-head cadmium zinc telluride-based gamma camera. Breast thickness was measured as the distance between the 2 detectors. Patient height, weight, body surface area, and body mass index were obtained from records. Lean body mass with the James equation (LBMJames) and Janmahasatian correction (LBMJanma) was calculated. Count density in the breast tissue was measured by drawing a region of interest around the central breast tissue of the right breast mediolateral-oblique view of the lower detector. Count density was expressed as cts/cm2/MBq of administered activity. Spearman correlation coefficient (rs) was calculated. Results: A total of 200 patients were analyzed. No dose infiltration was suspected at any injection. Average administered activity was 292 MBq (SD, 13.8 MBq; range, 247-326 MBq). Average count density was 7.2 cts/cm2/MBq (SD, 2.7 cts/cm2/MBq; range, 3.1-17.8 cts/cm2/MBq). MBI count density was weakly negatively correlated with height (rs = -0.18; P = 0.01), weight (rs = -0.23; p = <0.001), body mass index (rs = -0.16; P = 0.02), body surface area (rs = -0.22; P = 0.002), LBMJames (rs = -0.23; P = 0.001), and LBMJanma (rs = -0.23; P = 0.001). No correlation was observed between count density and breast thickness (rs = 0.06; P = 0.37). Conclusion: Our results suggest a lack of relationship between uptake of 99mTc-sestamibi in breast tissue and body size or compressed breast thickness. Altering from the standard 300 MBq of administered activity for larger patients is likely unnecessary. PMID- 29599400 TI - Can 68Ga-DOTA Peptides Be Potential Radiotracers for PET Imaging of the Spleen? AB - On radionuclide somatostatin receptor imaging studies, the spleen shows high physiologic uptake. Reducing the intensity of the image settings helps to better assess the distribution of radiotracer in the spleen. In our routine studies, we incidentally recognized that 68Ga-DOTANOC PET provides higher-resolution splenic images than 111In-octreotide SPECT. Autoradiography and immunohistochemistry studies have shown that somatostatin receptors are located mainly in the red pulp of the spleen. The distribution of 68Ga-DOTANOC in the spleen appears to correlate with the distribution of red pulp. In this article, we present 68Ga DOTANOC PET/CT spleen images of our patients. PMID- 29599401 TI - The Effect of New Formulas for Lean Body Mass on Lean-Body-Mass-Normalized SUV in Oncologic 18F-FDG PET/CT. AB - Because of better precision and intercompatibility, the use of lean body mass (LBM) as a mass estimate in the calculation of SUV (SUL) has become more common in research and clinical studies today. Thus, the equations deciding this quantity must be those that best represent the actual body composition. Methods: LBM was calculated for 44 patients examined with 18F-FDG PET/CT scans by means of the sex-specific predictive equations of James and Janmahasatians, and the results were validated using a CT-based method that makes use of the eyes-to thighs CT component of the PET/CT aquisition and segments the voxels according to Hounsfield units. Intraclass correlation coefficients and Bland-Altman plots were used to assess agreement between the various methods. Results: A mean difference of 6.3 kg (limits of agreement, -15.1 to 2.5 kg) between [Formula: see text] and [Formula: see text] was found. This difference was higher than the 3.8-kg difference observed between [Formula: see text] and [Formula: see text] (limits of agreement, -12.5 to 4.9 kg). In addition, [Formula: see text] had a higher intraclass correlation coefficient with [Formula: see text] (0.87; 95% confidence interval, 0.60-0.94) than with [Formula: see text] (0.77; 95% confidence interval, 0.11-0.91). Thus, we obtained better agreement between [Formula: see text] and [Formula: see text] Although there were exceptions, the overall effect on SUL was that [Formula: see text] was greater than [Formula: see text] Conclusion: We have verified the reliability of the suggested [Formula: see text] formulas with a CT-derived reference standard. Compared with the more traditional and available set of [Formula: see text] equations, the [Formula: see text] formulas tend to yield better agreement.

PMID- 29599403 TI - 18F-FDG PET/CT Can Predict Development of Thyroiditis Due to Immunotherapy for Lung Cancer. AB - Our primary purpose was to determine whether increased 18F-FDG uptake in the thyroid gland predicts development of thyroiditis with subsequent hypothyroidism in patients undergoing immunotherapy with nivolumab for lung cancer. Secondarily, we determined whether 18F-FDG uptake in the thyroid gland correlates with number of administered cycles of nivolumab. Methods: Retrospective chart review over 2 y found 18 lung cancer patients treated with nivolumab who underwent 18F-FDG PET/CT before and during therapy. SUVmean, SUVmax, and total lesion glycolysis of the thyroid gland were measured. SUVs were also measured for the pituitary gland, liver, and spleen. Patients underwent monthly thyroid testing. PET/CT parameters were analyzed by unpaired t testing for differences between 2 groups (patients who developed hypothyroidism and those who did not). Correlation between development of thyroiditis and number of cycles of nivolumab was also tested. Results: Six of 18 patients developed hypothyroidism. The t test comparing the 2 groups demonstrated significant differences in SUVmean (P = 0.04), SUVmax (P = 0.04), and total lesion glycolysis (P = 0.02) of the thyroid gland. Two of 4 patients who developed thyroiditis and had increased 18F-FDG uptake in the thyroid gland had a normal TSH level at the time of follow-up 18F-FDG PET/CT. Patients who developed thyroiditis with subsequent hypothyroidism stayed longer on therapy (10.6 cycles) than patients without thyroiditis (7.6 cycles), but the trend was not statistically significant. No significant difference in PET/CT parameters was observed for pituitary gland, liver, or spleen. Conclusion:18F-FDG PET/CT can predict the development of thyroiditis with subsequent hypothyroidism before laboratory testing. Further study is required to confirm the positive trend between thyroiditis and duration of therapy. PMID- 29599404 TI - Time-of-Flight Information Improved the Detectability of Subcentimeter Spheres Using a Clinical PET/CT Scanner. AB - Recent advancements in clinical PET/CT scanners have improved the detectability of small lesions. However, the ideal reconstruction parameters for detecting small lesions have not yet been sufficiently clarified. The purpose of this study was to investigate the detectability of subcentimeter spheres using a clinical PET/CT scanner. Methods: We used a clinical PET/CT scanner to obtain the data of a National Electrical Manufacturers Association body phantom consisting of 6 small spheres (inner diameters, 4.0, 5.0, 6.2, 7.9, 10, and 37 mm) containing 18F solution. The background activity was 2.65 kBq/mL, and the sphere-to-background ratio was 8. The PET data obtained for 2 and 120 min were reconstructed using ordered-subsets expectation maximization (OSEM), OSEM + point-spread function (PSF), and OSEM + time-of-flight (TOF) with voxel sizes of 2.04 * 2.04 * 2.00 mm (2-mm voxels) and 4.07 * 4.07 * 3.99 mm (4-mm voxels). A gaussian filter was not used. The image quality was evaluated by visual assessment, as well as by physical assessment of the detectability index and recovery coefficients. Results: According to the visual assessment, the detectability of the spheres improved using TOF and a longer acquisition. Using the OSEM+TOF model, the smallest visually detected spheres were 5 mm in diameter with a 120-min acquisition and 6 mm in diameter with a 2-min acquisition. According to physical assessment, the detectability of spheres 10 mm or smaller using the OSEM+TOF image was superior to that using the OSEM image. In addition, the detectability of each hot sphere and recovery coefficient with 2-mm voxels was superior to that with 4-mm voxels. Although OSEM+PSF images showed less background noise, detectability and the recovery coefficient were not improved for spheres 8 mm or smaller. Conclusion: The TOF model with 2-mm voxels improved the detectability of subcentimeter hot spheres on a clinical PET/CT scanner. PMID- 29599405 TI - Transketolase Regulates the Metabolic Switch to Control Breast Cancer Cell Metastasis via the alpha-Ketoglutarate Signaling Pathway. AB - Although metabolic reprogramming is recognized as a hallmark of tumorigenesis and progression, little is known about metabolic enzymes and oncometabolites that regulate breast cancer metastasis, and very few metabolic molecules have been identified as potential therapeutic targets. In this study, the transketolase (TKT) expression correlated with tumor size in the 4T1/BALB/c syngeneic model. In addition, TKT expression was higher in lymph node metastases compared with primary tumor or normal tissues of patients, and high TKT levels were associated with poor survival. Depletion of TKT or addition of alpha-ketoglutarate (alphaKG) enhanced the levels of tumor suppressors succinate dehydrogenase and fumarate hydratase (FH), decreasing oncometabolites succinate and fumarate, and further stabilizing HIF prolyl hydroxylase 2 (PHD2) and decreasing HIF1alpha, ultimately suppressing breast cancer metastasis. Reduced TKT or addition of alphaKG mediated a dynamic switch of glucose metabolism from glycolysis to oxidative phosphorylation. Various combinations of the TKT inhibitor oxythiamine, docetaxel, and doxorubicin enhanced cell death in triple-negative breast cancer (TNBC) cells. Furthermore, oxythiamine treatment led to increased levels of alphaKG in TNBC cells. Together, our study has identified a novel TKT-mediated alphaKG signaling pathway that regulates breast cancer oncogenesis and can be exploited as a modality for improving therapy.Significance: These findings uncover the clinical significance of TKT in breast cancer progression and metastasis and demonstrate effective therapy by inhibiting TKT or by adding alphaKG.

PMID- 29599408 TI - Non-parathyroid hypercalcemia associated with paraffin oil injection in 12 younger male bodybuilders: a case series. AB - INTRODUCTION: Injection of paraffin oil to augment muscles size is a troubling phenomenon known to cause a foreign body reaction with formation of granulomas. In a few case reports, long-term side effects have been reported in terms of hypercalcemia and renal failure. METHODS: We identified a case series of 12 male bodybuilders presenting with non-parathyroid hypercalcemia who previously had injected paraffin oil to increase muscles size. RESULTS: At admission, all patients had moderate-to-severe hypercalcemia with suppressed PTH levels and impaired renal function. Calcitriol levels were within the normal range or slightly elevated. Follow-up measurements showed marked hypercalciuria with nearly normal levels of bone turnover markers. A correlation was found between levels of peptidyl dipeptidase and calcitriol (R = 0.812, P = 0.050). Treatment with antiresorptive agents seemed less effective than glucocorticoids, which resulted in a significantly lowering of ionized calcium levels and improved renal function, although no patients were cured by this treatment. Immunosuppression with azathioprine or mycophenolate may have a glucocorticoid-saving effect. One patient had surgery with removal of affected muscle tissue, without any apparent effect on plasma calcium levels. CONCLUSION: The hypercalcemia and associated hypercalciuria seems to be due to an intestinal hyperabsorption of calcium. It remains to be elucidated, whether an increased calcitriol synthesis within granulomas is the only (main) mechanism by which intestinal calcium absorption is increased. Glucocorticoids seem most appropriate as the first choice for treatment. Bodybuilders should be warned against use of intramuscular oil injections (and other substances), as this may have severe adverse health consequences. PMID- 29599407 TI - Microstructural white matter alterations and hippocampal volumes are associated with cognitive deficits in craniopharyngioma. AB - CONTEXT: Patients with craniopharyngioma (CP) and hypothalamic lesions (HL) have cognitive deficits. Which neural pathways are affected is unknown. OBJECTIVE: To determine whether there is a relationship between microstructural white matter (WM) alterations detected with diffusion tensor imaging (DTI) and cognition in adults with childhood-onset CP. DESIGN: A cross-sectional study with a median follow-up time of 22 (6-49) years after operation. SETTING: The South Medical Region of Sweden (2.5 million inhabitants). PARTICIPANTS: Included were 41 patients (24 women, >=17 years) surgically treated for childhood-onset CP between 1958-2010 and 32 controls with similar age and gender distributions. HL was found in 23 patients. MAIN OUTCOME MEASURES: Subjects performed cognitive tests and magnetic resonance imaging, and images were analyzed using DTI of uncinate fasciculus, fornix, cingulum, hippocampus and hypothalamus as well as hippocampal volumetry. RESULTS: Right uncinate fasciculus was significantly altered (P <= 0.01). Microstructural WM alterations in left ventral cingulum were significantly associated with worse performance in visual episodic memory, explaining approximately 50% of the variation. Alterations in dorsal cingulum were associated with worse performance in immediate, delayed recall and recognition, explaining 26-38% of the variation, and with visuospatial ability and executive function, explaining 19-29%. Patients who had smaller hippocampal volume had worse general knowledge (P = 0.028), and microstructural WM alterations in hippocampus were associated with a decline in general knowledge and episodic visual memory. CONCLUSIONS: A structure to function relationship is suggested between microstructural WM alterations in cingulum and in hippocampus with cognitive deficits in CP. PMID- 29599409 TI - Functional Precision Medicine Identifies Novel Druggable Targets and Therapeutic Options in Head and Neck Cancer. AB - Purpose: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide, with high mortality and a lack of targeted therapies. To identify and prioritize druggable targets, we performed genome analysis together with genome-scale siRNA and oncology drug profiling using low-passage tumor cells derived from a patient with treatment-resistant HPV-negative HNSCC.Experimental Design: A tumor cell culture was established and subjected to whole-exome sequencing, RNA sequencing, comparative genome hybridization, and high-throughput phenotyping with a siRNA library covering the druggable genome and an oncology drug library. Secondary screens of candidate target genes were performed on the primary tumor cells and two nontumorigenic keratinocyte cell cultures for validation and to assess cancer specificity. siRNA screens of the kinome on two isogenic pairs of p53-mutated HNSCC cell lines were used to determine generalizability. Clinical utility was addressed by performing drug screens on two additional HNSCC cell cultures derived from patients enrolled in a clinical trial.Results: Many of the identified copy number aberrations and somatic mutations in the primary tumor were typical of HPV(-) HNSCC, but none pointed to obvious therapeutic choices. In contrast, siRNA profiling identified 391 candidate target genes, 35 of which were preferentially lethal to cancer cells, most of which were not genomically altered. Chemotherapies and targeted agents with strong tumor-specific activities corroborated the siRNA profiling results and included drugs that targeted the mitotic spindle, the proteasome, and G2-M kinases WEE1 and CHK1 We also show the feasibility of ex vivo drug profiling for patients enrolled in a clinical trial.Conclusions: High-throughput phenotyping with siRNA and drug libraries using patient-derived tumor cells prioritizes mutated driver genes and identifies novel drug targets not revealed by genomic profiling. Functional profiling is a promising adjunct to DNA sequencing for precision oncology. Clin Cancer Res; 24(12); 2828-43. (c)2018 AACR. PMID- 29599411 TI - CD103+ Tumor-Resident CD8+ T Cells Are Associated with Improved Survival in Immunotherapy-Naive Melanoma Patients and Expand Significantly During Anti-PD-1 Treatment. AB - Purpose: Therapeutic blockade of immune checkpoints has revolutionized cancer treatment. Durable responses, however, occur in less than half of those treated, and efforts to improve treatment efficacy are confounded by a lack of understanding of the characteristics of the cells that initiate antitumor immune response.Patients and Methods: We performed multiparameter flow cytometry and quantitative multiplex immunofluorescence staining on tumor specimens from immunotherapy-naive melanoma patients and longitudinal biopsy specimen obtained from patients undergoing anti-PD-1 therapy.Results: Increased numbers of CD69+CD103+ tumor-resident CD8+ T cells were associated with improved melanoma specific survival in immunotherapy-naive melanoma patients. Local IL15 expression levels strongly correlated with these tumor-resident T-cell numbers. The expression of several immune checkpoints including PD-1 and LAG3 was highly enriched in this subset, and these cells significantly expanded early during anti PD-1 immunotherapy.Conclusions: Tumor-resident CD8+ T-cell numbers are more prognostic than total CD8+ T cells in metastatic melanoma. In addition, they are likely to initiate response to anti-PD-1 and anti-LAG-3 treatments. We propose that the immune profile of these cells prior to treatment could inform strategies for immune checkpoint blockade. Clin Cancer Res; 24(13); 3036-45. (c)2018 AACR. PMID- 29599410 TI - Clinical Utility of Cell-Free DNA for the Detection of ALK Fusions and Genomic Mechanisms of ALK Inhibitor Resistance in Non-Small Cell Lung Cancer. AB - Purpose: Patients with advanced non-small cell lung cancer (NSCLC) whose tumors harbor anaplastic lymphoma kinase (ALK) gene fusions benefit from treatment with ALK inhibitors (ALKi). Analysis of cell-free circulating tumor DNA (cfDNA) may provide a noninvasive way to identify ALK fusions and actionable resistance mechanisms without an invasive biopsy.Patients and Methods: The Guardant360 (G360; Guardant Health) deidentified database of NSCLC cases was queried to identify 88 consecutive patients with 96 plasma-detected ALK fusions. G360 is a clinical cfDNA next-generation sequencing (NGS) test that detects point mutations, select copy number gains, fusions, insertions, and deletions in plasma.Results: Identified fusion partners included EML4 (85.4%), STRN (6%), and KCNQ, KLC1, KIF5B, PPM1B, and TGF (totaling 8.3%). Forty-two ALK-positive patients had no history of targeted therapy (cohort 1), with tissue ALK molecular testing attempted in 21 (5 negative, 5 positive, and 11 tissue insufficient). Follow-up of 3 of the 5 tissue-negative patients showed responses to ALKi. Thirty one patients were tested at known or presumed ALKi progression (cohort 2); 16 samples (53%) contained 1 to 3 ALK resistance mutations. In 13 patients, clinical status was unknown (cohort 3), and no resistance mutations or bypass pathways were identified. In 6 patients with known EGFR-activating mutations, an ALK fusion was identified on progression (cohort 4; 4 STRN, 1 EML4; one both STRN and EML4); five harbored EGFR T790M.Conclusions: In this cohort of cfDNA-detected ALK fusions, we demonstrate that comprehensive cfDNA NGS provides a noninvasive means of detecting targetable alterations and characterizing resistance mechanisms on progression.

AB - Purpose: To evaluate the potential of hyperpolarized [1-13C]-pyruvate magnetic resonance spectroscopic imaging (MRSI) of prostate cancer as a predictive biomarker for targeting the Warburg effect.Experimental Design: Two human prostate cancer cell lines (DU145 and PC3) were grown as xenografts. The conversion of pyruvate to lactate in xenografts was measured with hyperpolarized [1-13C]-pyruvate MRSI after systemic delivery of [1-13C] pyruvic acid. Steady state metabolomic analysis of xenograft tumors was performed with mass spectrometry and steady-state lactate concentrations were measured with proton (1H) MRS. Perfusion and oxygenation of xenografts were measured with electron paramagnetic resonance (EPR) imaging with OX063. Tumor growth was assessed after lactate dehydrogenase (LDH) inhibition with FX-11 (42 MUg/mouse/day for 5 days * 2 weekly cycles). Lactate production, pyruvate uptake, extracellular acidification rates, and oxygen consumption of the prostate cancer cell lines were analyzed in vitro LDH activity was assessed in tumor homogenates.Results: DU145 tumors demonstrated an enhanced conversion of pyruvate to lactate with hyperpolarized [1-13C]-pyruvate MRSI compared with PC3 and a corresponding greater sensitivity to LDH inhibition. No difference was observed between PC3 and DU145 xenografts in steady-state measures of pyruvate fermentation, oxygenation, or perfusion. The two cell lines exhibited similar sensitivity to FX-11 in vitro LDH activity correlated to FX-11 sensitivity.Conclusions: Hyperpolarized [1-13C] pyruvate MRSI of prostate cancer predicts efficacy of targeting the Warburg effect.

AB - The calcium-sensing receptor (CASR) is a class C G-protein-coupled receptor (GPCR) that detects extracellular calcium concentrations, and modulates parathyroid hormone secretion and urinary calcium excretion to maintain calcium homeostasis. The CASR utilises multiple heterotrimeric G-proteins to mediate signalling effects including activation of intracellular calcium release; mitogen activated protein kinase (MAPK) pathways; membrane ruffling; and inhibition of cAMP production. By studying germline mutations in the CASR and proteins within its signalling pathway that cause hyper- and hypocalcaemic disorders, novel mechanisms governing GPCR signalling and trafficking have been elucidated. This review focusses on two recently described pathways that provide novel insights into CASR signalling and trafficking mechanisms. The first, identified by studying a CASR gain-of-function mutation that causes autosomal dominant hypocalcaemia (ADH), demonstrated a structural motif located between the third transmembrane domain and the second extracellular loop of the CASR that mediates biased signalling by activating a novel beta-arrestin-mediated G-protein independent pathway. The second, in which the mechanism by which adaptor protein 2 sigma-subunit (AP2sigma) mutations cause familial hypocalciuric hypercalcaemia (FHH) was investigated, demonstrated that AP2sigma mutations impair CASR internalisation and reduce multiple CASR-mediated signalling pathways. Furthermore, these studies showed that the CASR can signal from the cell surface using multiple G-protein pathways, whilst sustained signalling is mediated only by the Gq/11 pathway. Thus, studies of FHH- and ADH-associated mutations have revealed novel steps by which CASR mediates signalling and compartmental bias, and these pathways could provide new targets for therapies for patients with calcaemic disorders.

AB - Purpose: Glioblastoma (GBM), a fatal brain cancer, contains a subpopulation of GBM stem-like cells (GSCs) that contribute to resistance to current therapy. Angiogenesis also plays a key role in GBM progression. Therefore, we developed a strategy to target the complex GBM microenvironment, including GSCs and tumor vasculature.Experimental Design: We evaluated the cytotoxic effects of VEFGR tyrosine kinase inhibitor (TKI) axitinib in vitro and then tested antitumor efficacy of axitinib in combination with oncolytic herpes simplex virus (oHSV) expressing antiangiogenic cytokine murine IL12 (G47Delta-mIL12) in two orthotopic GSC-derived GBM models: patient-derived recurrent MGG123 GSCs, forming vascular xenografts in immunodeficient mice; and mouse 005 GSCs, forming syngeneic tumors in immunocompetent mice.Results: GSCs form endothelial-like tubes and were sensitive to axitinib. G47Delta-mIL12 significantly improved survival, as did axitinib, while dual combinations further extended survival significantly compared with single therapies alone in both models. In MGG123 tumors, axitinib was effective only at high doses (50 mg/kg), alone and in combination with G47Delta-mIL12, and this was associated with greatly decreased vascularity, increased macrophage infiltration, extensive tumor necrosis, and PDGFR/ERK pathway inhibition. In the mouse 005 model, antiglioma activity, after single and combination therapy, was only observed in immunocompetent mice and not the T-cell deficient athymic mice. Interestingly, immune checkpoint inhibition did not improve efficacy.Conclusions: Systemic TKI (axitinib) beneficially combines with G47Delta-mIL12 to enhance antitumor efficacy in both immunodeficient and immunocompetent orthotopic GBM models. Our results support further investigation of TKIs in combination with oHSV for GBM treatment. Clin Cancer Res; 24(14); 3409 22. (c)2018 AACR.

PMID- 29599416 TI - Low-protein diet in puberty impairs testosterone output and energy metabolism in male rats. AB - We examined the long-term effects of protein restriction during puberty on the function of hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary gonadal (HPG) axes in male rats. Male Wistar rats from the age of 30 to 60 days were fed a low-protein diet (4%, LP). A normal-protein diet (20.5%) was reintroduced to rats from the age of 60 to 120 days. Control rats were fed a normal-protein diet throughout life (NP). Rats of 60 or 120 days old were killed. Food consumption, body weight, visceral fat deposits, lipid profile, glycemia, insulinemia, corticosteronemia, adrenocorticotropic hormone (ACTH), testosteronemia and leptinemia were evaluated. Glucose-insulin homeostasis, pancreatic-islet insulinotropic response, testosterone production and hypothalamic protein expression of the androgen receptor (AR), glucocorticoid receptor (GR) and leptin signaling pathway were also determined. LP rats were hypophagic, leaner, hypoglycemic, hypoinsulinemic and hypoleptinemic at the age of 60 days (P < 0.05). These rats exhibited hyperactivity of the HPA axis, hypoactivity of the HPG axis and a weak insulinotropic response (P < 0.01). LP rats at the age of 120 days were hyperphagic and exhibited higher visceral fat accumulation, hyperleptinemia and dyslipidemia; lower blood ACTH, testosterone and testosterone release; and reduced hypothalamic expression of AR, GR and SOCS3, with a higher pSTAT3/STAT3 ratio (P < 0.05). Glucose-insulin homeostasis was disrupted and associated with hyperglycemia, hyperinsulinemia and increased insulinotropic response of the pancreatic islets. The cholinergic and glucose pancreatic-islet responses were small in 60-day-old LP rats but increased in 120 day-old LP rats. The hyperactivity of the HPA axis and the suppression of the HPG axis caused by protein restriction at puberty contributed to energy and metabolic disorders as long-term consequences.

Biologically inspired robots are just one example of the application of knowledge of the natural world to engineering problems. However, recent work by biologists and interdisciplinary teams have flipped this approach, using robots and physical models to set the course for experiments on biological systems and to generate new hypotheses for biological research. We call this approach robotics-inspired biology; it involves performing experiments on robotic systems aimed at the discovery of new biological phenomena or generation of new hypotheses about how organisms function that can then be tested on living organisms. This new and exciting direction has emerged from the extensive use of physical models by biologists and is already making significant advances in the areas of biomechanics, locomotion, neuromechanics and sensorimotor control. Here, we provide an introduction and overview of robotics-inspired biology, describe two case studies and suggest several directions for the future of this exciting new research area. PMID- 29599418 TI - New workflow for classification of genetic variants' pathogenicity applied to hereditary recurrent fevers by the International Study Group for Systemic Autoinflammatory Diseases (INSAID). AB - BACKGROUND: Hereditary recurrent fevers (HRFs) are rare inflammatory diseases sharing similar clinical symptoms and effectively treated with anti-inflammatory biological drugs. Accurate diagnosis of HRF relies heavily on genetic testing. OBJECTIVES: This study aimed to obtain an experts' consensus on the clinical significance of gene variants in four well-known HRF genes: MEFV, TNFRSF1A, NLRP3 and MVK. METHODS: We configured a MOLGENIS web platform to share and analyse pathogenicity classifications of the variants and to manage a consensus-based classification process. Four experts in HRF genetics submitted independent classifications of 858 variants. Classifications were driven to consensus by recruiting four more expert opinions and by targeting discordant classifications in five iterative rounds. RESULTS: Consensus classification was reached for 804/858 variants (94%). None of the unsolved variants (6%) remained with opposite classifications (eg, pathogenic vs benign). New mutational hotspots were found in all genes. We noted a lower pathogenic variant load and a higher fraction of variants with unknown or unsolved clinical significance in the MEFV gene. CONCLUSION: Applying a consensus-driven process on the pathogenicity assessment of experts yielded rapid classification of almost all variants of four HRF genes. The high-throughput database will profoundly assist clinicians and geneticists in the diagnosis of HRFs. The configured MOLGENIS platform and consensus evolution protocol are usable for assembly of other variant pathogenicity databases. The MOLGENIS software is available for reuse at http://github.com/molgenis/molgenis; the specific HRF configuration is available at http://molgenis.org/said/. The HRF pathogenicity classifications will be published on the INFEVERS database at https://fmf.igh.cnrs.fr/ISSAID/infevers/. PMID- 29599419 TI - Chitayat-Hall and Schaaf-Yang syndromes:a common aetiology: expanding the phenotype of MAGEL2-related disorders. AB - BACKGROUND: Chitayat-Hall syndrome, initially described in 1990, is a rare condition characterised by distal arthrogryposis, intellectual disability, dysmorphic features and hypopituitarism, in particular growth hormone deficiency. The genetic aetiology has not been identified. METHODS AND RESULTS: We identified three unrelated families with a total of six affected patients with the clinical manifestations of Chitayat-Hall syndrome. Through whole exome or whole genome sequencing, pathogenic variants in the MAGEL2 gene were identified in all affected patients. All disease-causing sequence variants detected are predicted to result in a truncated protein, including one complex variant that comprised a deletion and inversion. CONCLUSIONS: Chitayat-Hall syndrome is caused by pathogenic variants in MAGEL2 and shares a common aetiology with the recently described Schaaf-Yang syndrome. The phenotype of MAGEL2-related disorders is expanded to include growth hormone deficiency as an important and treatable complication. PMID- 29599420 TI - Brown adipose tissue whitening leads to brown adipocyte death and adipose tissue inflammation. AB - In mammals, white adipose tissue (WAT) stores and releases lipids, whereas brown adipose tissue (BAT) oxidizes lipids to fuel thermogenesis. In obese individuals, WAT undergoes profound changes; it expands, becomes dysfunctional, and develops a low-grade inflammatory state. Importantly, BAT content and activity decline in obese subjects, mainly as a result of the conversion of brown adipocytes to white like unilocular cells. Here, we show that BAT "whitening" is induced by multiple factors, including high ambient temperature, leptin receptor deficiency, beta adrenergic signaling impairment, and lipase deficiency, each of which is capable of inducing macrophage infiltration, brown adipocyte death, and crown-like structure (CLS) formation. Brown-to-white conversion and increased CLS formation were most marked in BAT from adipose triglyceride lipase (Atgl)-deficient mice, where, according to transmission electron microscopy, whitened brown adipocytes contained enlarged endoplasmic reticulum, cholesterol crystals, and some degenerating mitochondria, and were surrounded by an increased number of collagen fibrils. Gene expression analysis showed that BAT whitening in Atgl-deficient mice was associated to a strong inflammatory response and NLRP3 inflammasome activation. Altogether, the present findings suggest that converted enlarged brown adipocytes are highly prone to death, which, by promoting inflammation in whitened BAT, may contribute to the typical inflammatory state seen in obesity.

AB - Objectives: To compare medical students' and residents' knowledge retention of assessment, diagnosis and treatment procedures, as well as a learning experience, of patients with spinal trauma after training with either a Virtual Patient case or a video-recorded traditional lecture. Methods: A total of 170 volunteers (85 medical students and 85 residents in orthopedic surgery) were randomly allocated (stratified for student/resident and gender) to either a video-recorded standard lecture or a Virtual Patient-based training session where they interactively assessed a clinical case portraying a motorcycle accident. The knowledge retention was assessed by a test immediately following the educational intervention and repeated after a minimum of 2 months. Participants' learning experiences were evaluated with exit questionnaires. A repeated-measures analysis of variance was applied on knowledge scores. A total of 81% (n = 138) of the participants completed both tests. Results: There was a small but significant decline in first and second test results for both groups (F(1, 135) = 18.154, p = 0.00). However, no significant differences in short-term and long-term knowledge retention were observed between the two teaching methods. The Virtual Patient group reported higher learning experience levels in engagement, stimulation, general perception, and expectations. Conclusions: Participants' levels engagement were reported in favor of the VP format. Similar knowledge retention was achieved through either a Virtual Patient or a recorded lecture. PMID- 29599422 TI - Fatal Acute Respiratory Distress Syndrome Due to Influenza A (H1N1) Infection in Patients After Kidney Transplantation: A Report of Five Cases. AB - BACKGROUND In the general population, swine influenza is a self-limited infection. Patients after kidney transplantation, however, are at increased risk for complications and mortality from influenza A (H1N1). Acute respiratory distress syndrome (ARDS) complicates up to 55% of influenza-related pneumonia in hospitalized patients and carries a mortality of 40-46%. We describe our experience in intensive care of kidney transplant patients with ARDS complicating influenza A (H1N1) pneumonia during a flu outbreak. CASE REPORT Five adult post kidney transplantation patients with progressive respiratory failure admitted to the ICU between February 2016 and April 2016 were included in this retrospectively analysis. All patients had influenza A (H1N1) viral pneumonia (confirmed with RT-PCR) complicated by ARDS and septic shock with multiple organ dysfunction syndrome. None of the patients received seasonal influenza vaccines. All patients had negative rapid influenza bedside tests, which resulted in delay of administration of antiviral therapy prior to admission to the ICU. All patients were managed with a lung protective ventilation strategy (average days of mechanical ventilation, 17.6+/-15.3). Three patients required additional therapies for refractory hypoxemia, including high positive end-expiratory pressure and prone positioning. Extracorporeal membrane oxygenation was not implemented. Treatment with oseltamivir was added to a broad-spectrum antibiotic on the first to the fifth day of intensive care. Despite these measures, all patients eventually died. CONCLUSIONS Despite great progress in the management of ARDS, based mostly on advanced mechanical ventilation, early antiviral treatment of pneumonia caused by influenza A (H1N1) and annual vaccinations seem essential in prevention and management of influenza A (H1N1) infection among kidney transplant recipients. PMID- 29599423 TI - Atypical Presentation of Gelsolin Amyloidosis in a Man of African Descent with a Novel Mutation in the Gelsolin Gene. AB - BACKGROUND Gelsolin amyloidosis is a very rare systemic disease presenting with a pathognomonic triad of corneal lattice dystrophy, cutis laxa, and polyneuropathy. The disease is mostly restricted to a Finnish population with known mutations (G654A, G654T) in exon 4 of the gelsolin gene. The mutations lead to errors in protein processing and folding, and ultimately leads to deposition of an amyloidogenic fragment in the extracellular space, causing the symptoms of disease. CASE REPORT We present a case of gelsolin amyloidosis in a male of African descent with an atypical clinical presentation including fevers, skin rash, polyneuropathy, and anemia. Gelsolin amyloidosis was diagnosed based on mass spectrometry of tissue samples. Importantly, a novel mutation in the gelsolin gene (C1375G) in exon 10 was found in this patient. His atypical presentation can possibly be attributed to the presence of a novel mutation in the gelsolin gene as the likely underlying cause of the syndrome. PCR primers were used to amplify the gelsolin gene from genomic DNA. Purified PCR products were then shipped to Eton Biosciences (San Diego, CA) for sequencing. CONCLUSIONS This study carries several important lessons relevant to the practice of medicine. First, the differential diagnosis for multisystem disease presentations should always include amyloidosis. Second, despite what has been uncovered about the molecular biology of disease, there is always more that can be discovered. Finally, further work to verify the link between this mutation and the clinical syndrome is still needed, as are effective treatments for this disease. PMID- 29599424 TI - Epidemiology and Seasonality of Respiratory Viruses Detected from Children with Respiratory Tract Infections in Wuxi, East China. AB - BACKGROUND Respiratory tract infections (RTIs) are the major causes of mortality and morbidity in children and lead to hospitalization in developing countries. However, little is known about the epidemiology and seasonality of respiratory viruses in the pediatric population in Wuxi, East China. MATERIAL AND METHODS We included all patients 14 years of age and below who presented with signs and symptoms of RTIs between January 2010 and December 2016. During this period, a total of 2160 children treated in Wuxi No. 2 People's Hospital were involved in our study. The clinical and sociodemographic data were recorded to describe the frequency and seasonality. Respiratory specimens were tested by multiplex real time PCR assays for virus identification. RESULTS More than 30% (35.19%, 760 samples) of the specimens showed evidence of infection with viruses, including respiratory syncytial virus (368 samples), influenza virus A (114 samples), influenza virus B (115 samples), parainfluenza virus I (29 samples), parainfluenza virus II (39 samples), parainfluenza virus III (13 samples), and adenovirus (82 samples); 48.99% of the children infected with viruses were under 12 months of age. Viruses were detected throughout all the year, with a peak in winter. CONCLUSIONS Our study found that RSV is the most important cause of RTIs in our region during winter. Our data provide a comprehensive understanding of the epidemiology and seasonality of virus, which may help to reduce the use of antibiotics and implement an effective approach for prevention, control, and treatment of RTIs, especially during its peak season. PMID- 29599425 TI - Two-component anomalous Hall effect in a magnetically doped topological insulator. AB - The anomalous Hall (AH) effect measurement has emerged as a powerful tool to gain deep insights into magnetic materials, such as ferromagnetic metals, magnetic semiconductors, and magnetic topological insulators (TIs). In Mn-doped Bi2Se3, however, the AH effect has never been reported despite a lot of previous studies. Here we report the observation of AH effect in (Bi,Mn)2Se3 thin films and show that the sign of AH resistances changes from positive to negative as the Mn concentration is increased. The positive and negative AH resistances are found to coexist in a crossover regime. Such a two-component AH effect and the sign reversal can also be obtained by electrical gating of lightly doped samples. Our results provide an important basis for understanding the puzzling interplay between the surface states, the bulk states, and various magnetic doping effects, as well as competing magnetic orders in magnetically doped TIs.

AB - : There is a lack of longitudinal data linking physical inactivity and chronic diseases among Mexicans. OBJECTIVE: To examine the relationship between total, leisure and occupational moderate-to-vigorous physical activity (MVPA) and incidence of type II diabetes (T2D) and hypertension in the Mexico City Diabetes Study. Study design and population. A prospective cohort study was conducted from 1989 to 2009 among 2282 men and non-pregnant women residing in six low-income neighborhoods in Mexico City. MAIN OUTCOME: Incidence of T2D and hypertension. RESULTS: After controlling for confounders, <1 MET/min/week of MVPA during leisure time was associated with higher risk of hypertension (HR 1.29, CI 95% 1.01, 1.66) and T2D (HR 1.31 CI 95% 1.00, 1.74). In addition, accumulating <1 MET/min/week of occupational MVPA was associated with higher risk of hypertension (HR 1.47, CI 95% 1.13, 1.90). CONCLUSION: The absence of leisure and occupational MVPA was associated with an increased risk of hypertension. However, no associations were found between occupational MVPA and T2D. PMID- 29599427 TI - A new artificial diet for western corn rootworm larvae is compatible with and detects resistance to all current Bt toxins. AB - Insect resistance to transgenic crops is a growing concern for farmers, regulatory agencies, the seed industry, and researchers. Since 2009, instances of field-evolved Bt resistance or cross resistance have been documented for each of the four Bt proteins available for western corn rootworm (WCR), a major insect pest. To characterize resistance, WCR populations causing unexpected damage to Bt maize are evaluated in plant and/or diet toxicity assays. Currently, it is not possible to make direct comparisons of data from different Bt proteins due to differing proprietary artificial diets. Our group has developed a new, publicly available diet (WCRMO-1) with improved nutrition for WCR larvae. For the current manuscript, we tested the compatibility of all Bt proteins currently marketed for WCR on the WCRMO-1 diet and specific proprietary diets corresponding to each toxin using a susceptible colony of WCR. We also tested WCR colonies selected for resistance to each protein to assess the ability of the diet toxicity assay to detect Bt resistance. The WCRMO-1 diet is compatible with each of the proteins and can differentiate resistant colonies from susceptible colonies for each protein. Our diet allows researchers to monitor resistance without the confounding nutritional differences present between diets. PMID- 29599428 TI - Temperature and Monsoon Tango in a Tropical Stalagmite: Last Glacial-Interglacial Climate Dynamics. AB - High-resolution paleoclimate data on stable isotopes in a stalagmite were coupled to glycerol dialkyl glycerol tetraethers (GDGTs). The Indian Summer Monsoon (ISM) transitioned from limited rainfall during the Last Glacial Maximum (LGM) to intense precipitation during early Holocene (22 to 6 ka). This was associated with changes in stalagmite growth, abundance of branched (br) and isoprenoid (iso) GDGTs, as well as delta18O, delta13C, Sr/Ca and GDGT-derived signals providing both temperature and moisture information. The reconstructed mean annual air temperature (MAAT) of the most modern stalagmite sample at ~19 degrees C, matches the surface and cave MAAT, but was ~4 degrees C lower during LGM. Warming at the end of LGM occurred before ISM strengthened and indicate 6 ka lag consistent with sea surface temperature records. The isotope records during the Younger Dryas show rapid progressions to dry conditions and weak monsoons, but these shifts are not coupled to TEX86. Moreover, change to wetter and stronger ISM, along with warmer Holocene conditions are not continuous indicating a decoupling of local temperatures from ISM. PMID- 29599429 TI - Temperature induced crossing in the optical bandgap of mono and bilayer MoS2 on SiO2. AB - Photoluminescence measurements in mono- and bilayer-MoS2 on SiO2 were undertaken to determine the thermal effect of the MoS2/SiO2 interface on the optical bandgap. The energy and intensity of the photoluminescence from monolayer MoS2 were lower and weaker than those from bilayer MoS2 at low temperatures, whilst the opposite was true at high temperatures above 200 K. Density functional theory calculations suggest that the observed optical bandgap crossover is caused by a weaker substrate coupling to the bilayer than to the monolayer. PMID- 29599430 TI - Helraiser intermediates provide insight into the mechanism of eukaryotic replicative transposition. AB - Helitrons are eukaryotic DNA transposons that have profoundly affected genome variability via capture and mobilization of host genomic sequences. Defining their mode of action is therefore important for understanding how genome landscapes evolve. Sequence similarities with certain prokaryotic mobile elements suggest a "rolling circle" mode of transposition, involving only a single transposon strand. Using the reconstituted Helraiser transposon to study Helitron transposition in cells and in vitro, we show that the donor site must be double stranded and that single-stranded donors will not suffice. Nevertheless, replication and integration assays demonstrate the use of only one of the transposon donor strands. Furthermore, repeated reuse of Helraiser donor sites occurs following DNA synthesis. In cells, circular double-stranded intermediates that serve as transposon donors are generated and replicated by Helraiser transposase. Cell-free experiments demonstrate strand-specific cleavage and strand transfer, supporting observations made in cells. PMID- 29599432 TI - Information-to-work conversion by Maxwell's demon in a superconducting circuit quantum electrodynamical system. AB - Information thermodynamics bridges information theory and statistical physics by connecting information content and entropy production through measurement and feedback control. Maxwell's demon is a hypothetical character that uses information about a system to reduce its entropy. Here we realize a Maxwell's demon acting on a superconducting quantum circuit. We implement quantum non demolition projective measurement and feedback operation of a qubit and verify the generalized integral fluctuation theorem. We also evaluate the conversion efficiency from information gain to work in the feedback protocol. Our experiment constitutes a step toward experimental studies of quantum information thermodynamics in artificially made quantum machines. PMID- 29599431 TI - Two-dimensional analysis provides molecular insight into flower scent of Lilium 'Siberia'. AB - Lily is a popular flower around the world not only because of its elegant appearance, but also due to its appealing scent. Little is known about the regulation of the volatile compound biosynthesis in lily flower scent. Here, we conducted an approach combining two-dimensional analysis and weighted gene co expression network analysis (WGCNA) to explore candidate genes regulating flower scent production. In the approach, changes of flower volatile emissions and corresponding gene expression profiles at four flower developmental stages and four circadian times were both captured by GC-MS and RNA-seq methods. By overlapping differentially-expressed genes (DEGs) that responded to flower scent changes in flower development and circadian rhythm, 3,426 DEGs were initially identified to be candidates for flower scent production, of which 1,270 were predicted as transcriptional factors (TFs). The DEGs were further correlated to individual flower volatiles by WGCNA. Finally, 37, 41 and 90 genes were identified as candidate TFs likely regulating terpenoids, phenylpropanoids and fatty acid derivatives productions, respectively. Moreover, by WGCNA several genes related to auxin, gibberellins and ABC transporter were revealed to be responsible for flower scent production. Thus, this strategy provides an important foundation for future studies on the molecular mechanisms involved in floral scent production. PMID- 29599434 TI - Coherent changes of wintertime surface air temperatures over North Asia and North America. AB - The surface temperature variance and its potential change with global warming are most prominent in winter over Northern Hemisphere mid-high latitudes. Consistent wintertime surface temperature variability has been observed over large areas in Eurasia and North America on a broad range of time scales. However, it remains a challenge to quantify where and how the coherent change of temperature anomalies occur over the two continents. Here we demonstrate the coherent change of wintertime surface temperature anomalies over North Asia and the central-eastern parts of North America for the period from 1951 to 2015. This is supported by the results from the empirical orthogonal function analysis of surface temperature and temperature trend anomalies over the Northern Hemisphere extratropical lands and the timeseries analysis of the regional averaged temperature anomalies over North Asia and the Great Plains and Great Lakes. The Asian-Bering-North American (ABNA) teleconnection provides a pathway to connect the regional temperature anomalies over the two continents. The ABNA is also responsible for the decadal variation of the temperature relationship between North Asia and North America. PMID- 29599433 TI - Chemical tunnel-splitting-engineering in a dysprosium-based molecular nanomagnet. AB - Total control over the electronic spin relaxation in molecular nanomagnets is the ultimate goal in the design of new molecules with evermore realizable applications in spin-based devices. For single-ion lanthanide systems, with strong spin-orbit coupling, the potential applications are linked to the energetic structure of the crystal field levels and quantum tunneling within the ground state. Structural engineering of the timescale of these tunneling events via appropriate design of crystal fields represents a fundamental challenge for the synthetic chemist, since tunnel splittings are expected to be suppressed by crystal field environments with sufficiently high-order symmetry. Here, we report the long missing study of the effect of a non-linear (C4) to pseudo-linear (D4d) change in crystal field symmetry in an otherwise chemically unaltered dysprosium complex. From a purely experimental study of crystal field levels and electronic spin dynamics at milliKelvin temperatures, we demonstrate the ensuing threefold reduction of the tunnel splitting. PMID- 29599435 TI - Improved efficiency of in situ protein analysis by proximity ligation using UnFold probes. AB - We have redesigned probes for in situ proximity ligation assay (PLA), resulting in more efficient localized detection of target proteins. In situ PLA depends on recognition of target proteins by pairs of antibody-oligonucleotide conjugates (PLA probes), which jointly give rise to DNA circles that template localized rolling circle amplification reactions. The requirement for dual recognition of the target proteins improves selectivity by ignoring any cross-reactivity not shared by the antibodies, and it allows detection of protein-protein interactions and post-translational modifications. We herein describe an improved design of the PLA probes -UnFold probes - where all elements required for formation of circular DNA strands are incorporated in the probes. Premature interactions between the UnFold probes are prevented by including an enzymatic "unfolding" step in the detection reactions. This allows DNA circles to form by pairs of reagents only after excess reagents have been removed. We demonstrate the performance of UnFold probes for detection of protein-protein interactions and post-translational modifications in fixed cells and tissues, revealing considerably more efficient signal generation. We also apply the UnFold probes to detect IL-6 in solution phase after capture on solid supports, demonstrating increased sensitivity over both normal sandwich enzyme-linked immunosorbent assays and conventional PLA assays. PMID- 29599436 TI - SIRT6 facilitates directional telomere movement upon oxidative damage. AB - Oxidative damage to telomeres leads to telomere attrition and genomic instability, resulting in poor cell viability. Telomere dynamics contribute to the maintenance of telomere integrity; however, whether oxidative damage induces telomere movement and how telomere mobility is regulated remain poorly understood. Here, we show that oxidative damage at telomeres triggers directional telomere movement. The presence of the human Sir2 homolog, Sirtuin 6 (SIRT6) is required for oxidative damage-induced telomeric movement. SIRT6 knock out (KO) cells show neither damage-induced telomere movement nor chromatin decondensation at damaged telomeres; both are observed in wild type (WT) cells. A deacetylation mutant of SIRT6 increases damage-induced telomeric movement in SIRT6 KO cells as well as WT SIRT6. SIRT6 recruits the chromatin-remodeling protein SNF2H to damaged telomeres, which appears to promote chromatin decondensation independent of its deacetylase activity. Together, our results suggest that SIRT6 plays a role in the regulation of telomere movement upon oxidative damage, shedding new light onto the function of SIRT6 in telomere maintenance. PMID- 29599437 TI - Predicting affective valence using cortical hemodynamic signals. AB - Ascribing affective valence to stimuli or mental states is a fundamental property of human experiences. Recent neuroimaging meta-analyses favor the workspace hypothesis for the neural underpinning of valence, in which both positive and negative values are encoded by overlapping networks but are associated with different patterns of activity. In the present study, we further explored this framework using functional near-infrared spectroscopy (fNIRS) in conjunction with multivariate analyses. We monitored the fronto-temporal and occipital hemodynamic activity of 49 participants during the viewing of affective images (passive condition) and during the imagination of affectively loaded states (active condition). Multivariate decoding techniques were applied to determine whether affective valence is encoded in the cortical areas assessed. Prediction accuracies of 89.90 +/- 13.84% and 85.41 +/- 14.43% were observed for positive versus neutral comparisons, and of 91.53 +/- 13.04% and 81.54 +/- 16.05% for negative versus neutral comparisons (passive/active conditions, respectively). Our results are consistent with previous studies using other neuroimaging modalities that support the affective workspace hypothesis and the notion that valence is instantiated by the same network, regardless of whether the affective experience is passively or actively elicited. PMID- 29599438 TI - The secretome from bovine mammosphere-derived cells (MDC) promotes angiogenesis, epithelial cell migration, and contains factors associated with defense and immunity. AB - Treatment of bovine mastitis with intramammary antibiotics is common, yet several concerns exist including failed efficacy for individual hosts or pathogens and the inability of approved drugs to revert mastitis-induced tissue damage to healthy tissue capable of returning to full milk production. These issues, in addition to aspects of public health such as accidental antibiotic residues in saleable milk and the potential for antimicrobial resistance, support the need to find alternative therapies for this costly disease. This study shows that the secretome, or collective factors, produced by mammosphere-derived cells (MDC) promotes angiogenesis, epithelial cell migration, and contains proteins associated with immunity and defense; all of which are necessary for healing damaged mammary gland tissue. Furthermore, we found that the MDC secretome remains effective after freezing and thawing, enhancing its therapeutic potential. Our results provide a foundation for further characterization of the individual secreted factors and the rationale for using the MDC secretome as a complementary treatment for bovine mastitis. PMID- 29599439 TI - Fiber-optic implant for simultaneous fluorescence-based calcium recordings and BOLD fMRI in mice. AB - Despite the growing popularity of blood oxygen level-dependent (BOLD) functional MRI (fMRI), understanding of its underlying principles is still limited. This protocol describes a technique for simultaneous measurement of neural activity using fluorescent calcium indicators together with the corresponding hemodynamic BOLD fMRI response in the mouse brain. Our early work using small-molecule fluorophores in rats gave encouraging results but was limited to acute measurements using synthetic dyes. Our latest procedure combines fMRI with optical detection of cell-type-specific virally delivered GCaMP6, a genetically encoded calcium indicator (GECI). GCaMP6 fluorescence, which increases upon calcium binding, is collected by a chronically implanted optical fiber, allowing longitudinal studies in mice. The chronic implant, placed horizontally on the skull, has an angulated tip that reflects light into the brain and is connected via fiber optics to a remote optical setup. The technique allows access to the neocortex and does not require adaptations of commercial MRI hardware. The hybrid approach permits fiber-optic calcium recordings with simultaneous artifact-free BOLD fMRI with full brain coverage and 1-s temporal resolution using standard gradient-echo echo-planar imaging (GE-EPI) sequences. The method provides robust, cell-type-specific readouts to link neural activity to BOLD signals, as emonstrated for task-free ('resting-state') conditions and in response to hind paw stimulation. These results highlight the power of fiber photometry combined with fMRI, which we aim to further advance in this protocol. The approach can be easily adapted to study other molecular processes using suitable fluorescent indicators. PMID- 29599440 TI - Genome-wide analysis of replication timing by next-generation sequencing with E/L Repli-seq. AB - This protocol is an extension to: Nat. Protoc. 6, 870-895 (2014); doi:10.1038/nprot.2011.328; published online 02 June 2011Cycling cells duplicate their DNA content during S phase, following a defined program called replication timing (RT). Early- and late-replicating regions differ in terms of mutation rates, transcriptional activity, chromatin marks and subnuclear position. Moreover, RT is regulated during development and is altered in diseases. Here, we describe E/L Repli-seq, an extension of our Repli-chip protocol. E/L Repli-seq is a rapid, robust and relatively inexpensive protocol for analyzing RT by next generation sequencing (NGS), allowing genome-wide assessment of how cellular processes are linked to RT. Briefly, cells are pulse-labeled with BrdU, and early and late S-phase fractions are sorted by flow cytometry. Labeled nascent DNA is immunoprecipitated from both fractions and sequenced. Data processing leads to a single bedGraph file containing the ratio of nascent DNA from early versus late S phase fractions. The results are comparable to those of Repli-chip, with the additional benefits of genome-wide sequence information and an increased dynamic range. We also provide computational pipelines for downstream analyses, for parsing phased genomes using single-nucleotide polymorphisms (SNPs) to analyze RT allelic asynchrony, and for direct comparison to Repli-chip data. This protocol can be performed in up to 3 d before sequencing, and requires basic cellular and molecular biology skills, as well as a basic understanding of Unix and R. PMID- 29599441 TI - The successes and future prospects of the linear antisense RNA amplification methodology. AB - It has been over a quarter of a century since the introduction of the linear RNA amplification methodology known as antisense RNA (aRNA) amplification. Whereas most molecular biology techniques are rapidly replaced owing to the fast-moving nature of development in the field, the aRNA procedure has become a base that can be built upon through varied uses of the technology. The technique was originally developed to assess RNA populations from small amounts of starting material, including single cells, but over time its use has evolved to include the detection of various cellular entities such as proteins, RNA-binding-protein associated cargoes, and genomic DNA. In this Perspective we detail the linear aRNA amplification procedure and its use in assessing various components of a cell's chemical phenotype. This procedure is particularly useful in efforts to multiplex the simultaneous detection of various cellular processes. These efforts are necessary to identify the quantitative chemical phenotype of cells that underlies cellular function. PMID- 29599442 TI - On-chip microfluidic production of cell-sized liposomes. AB - In this protocol, we describe a recently developed on-chip microfluidic method to form monodisperse, cell-sized, unilamellar, and biocompatible liposomes with excellent encapsulation efficiency. Termed octanol-assisted liposome assembly (OLA), it resembles bubble-blowing on a microscopic scale. Hydrodynamic flow focusing of two immiscible fluid streams (an aqueous phase and a lipid-containing 1-octanol phase) by orthogonal outer aqueous streams gives rise to double emulsion droplets. As the lipid bilayer assembles along the interface, each emulsion droplet quickly evolves into a liposome and a 1-octanol droplet. OLA has several advantages as compared with other on-chip techniques, such as a very fast liposome maturation time (a few minutes), a relatively straightforward and completely on-chip setup, and a biologically relevant liposome size range (5-20 MUm). Owing to the entire approach being on-chip, OLA enables high-throughput liposome production (typical rate of tens of Hz) using low sample volumes (~10 MUl). For prolonged on-chip experimentation, liposomes are subsequently purified by removing the 1-octanol droplets. For device fabrication, a reusable silicon template is produced in a clean room facility using electron-beam lithography followed by dry reactive ion etching, which takes ~3 h. The patterned silicon template is used to prepare polydimethylsiloxane (PDMS)-based microfluidic devices in the wet lab, followed by a crucial surface treatment; the whole process takes ~2 d. Liposomes can be produced in ~1 h and further manipulated, depending on the experimental setup. OLA offers an ideal microfluidic platform for diverse bottom-up biotechnology studies by enabling creation of synthetic cells, microreactors and bioactive cargo delivery systems, and also has potential as an analytical tool. PMID- 29599443 TI - Genome-wide identification of natural RNA aptamers in prokaryotes and eukaryotes. AB - RNAs are well-suited to act as cellular sensors that detect and respond to metabolite changes in the environment, due to their ability to fold into complex structures. Here, we introduce a genome-wide strategy called PARCEL that experimentally identifies RNA aptamers in vitro, in a high-throughput manner. By applying PARCEL to a collection of prokaryotic and eukaryotic organisms, we have revealed 58 new RNA aptamers to three key metabolites, greatly expanding the list of natural RNA aptamers. The newly identified RNA aptamers exhibit significant sequence conservation, are highly structured and show an unexpected prevalence in coding regions. We identified a prokaryotic precursor tmRNA that binds vitamin B2 (FMN) to facilitate its maturation, as well as eukaryotic mRNAs that bind and respond to FMN, suggesting FMN as the second RNA-binding ligand to affect eukaryotic expression. PARCEL results show that RNA-based sensing and gene regulation is more widespread than previously appreciated in different organisms. PMID- 29599444 TI - Environmental complexity buffers against stress-induced negative judgement bias in female chickens. AB - Cognitive processes are often biased by emotions. In humans, affective disorders are accompanied by pessimistic judgement, while optimistic judgement is linked to emotional stability. Similar to humans, animals tend to interpret ambiguous stimuli negatively after experiencing stressful events, although the long-lasting impact on judgement bias has rarely been investigated. We measure judgement bias in female chicks (Gallus gallus domesticus) after exposure to cold stress, and before and after exposure to additional unpredictable stressors. Additionally, we explore if brain monoamines can explain differences in judgement bias. Chicks exposed to cold stress did not differ in judgement bias compared to controls, but showed sensitivity to additional stressors by having higher motivation for social reinstatement. Environmental complexity reduced stress-induced negative judgement bias, by maintaining an optimistic bias in individuals housed in complex conditions even after stress exposure. Moreover, judgement bias was related to dopamine turnover rate in mesencephalon, with higher activity in individuals that had a more optimistic response. These results demonstrate that environmental complexity can buffer against negative effects of additive stress and that dopamine relates to judgement bias in chicks. These results reveal that both internal and external factors can mediate emotionally biased judgement in animals, thus showing similarities to findings in humans. PMID- 29599445 TI - Recruitment kinetics of the homologous recombination pathway in procyclic forms of Trypanosoma brucei after ionizing radiation treatment. AB - One of the most important mechanisms for repairing double-strand breaks (DSBs) in model eukaryotes is homologous recombination (HR). Although the genes involved in HR have been found in Trypanosoma brucei and studies have identified some of the proteins that participate in this HR pathway, the recruitment kinetics of the HR machinery onto DNA during DSB repair have not been clearly elucidated in this organism. Using immunofluorescence, protein DNA-bound assays, and DNA content analysis, we established the recruitment kinetics of the HR pathway in response to the DSBs generated by ionizing radiation (IR) in procyclic forms of T. brucei. These kinetics involved the phosphorylation of histone H2A and the sequential recruitment of the essential HR players Exo1, RPA, and Rad51. The process of DSB repair took approximately 5.5 hours. We found that DSBs led to a decline in the G2/M phase after IR treatment, concomitant with cell cycle arrest in the G1/S phase. This finding suggests that HR repairs DSBs faster than the other possible DSB repair processes that act during the G1/S transition. Taken together, these data suggest that the interplay between DNA damage detection and HR machinery recruitment is finely coordinated, allowing these parasites to repair DNA rapidly after DSBs during the late S/G2 proficient phases. PMID- 29599446 TI - Valence and spin states of iron are invisible in Earth's lower mantle. AB - Heterogeneity in Earth's mantle is a record of chemical and dynamic processes over Earth's history. The geophysical signatures of heterogeneity can only be interpreted with quantitative constraints on effects of major elements such as iron on physical properties including density, compressibility, and electrical conductivity. However, deconvolution of the effects of multiple valence and spin states of iron in bridgmanite (Bdg), the most abundant mineral in the lower mantle, has been challenging. Here we show through a study of a ferric-iron-only (Mg0.46Fe3+0.53)(Si0.49Fe3+0.51)O3 Bdg that Fe3+ in the octahedral site undergoes a spin transition between 43 and 53 GPa at 300 K. The resolved effects of the spin transition on density, bulk sound velocity, and electrical conductivity are smaller than previous estimations, consistent with the smooth depth profiles from geophysical observations. For likely mantle compositions, the valence state of iron has minor effects on density and sound velocities relative to major cation composition. PMID- 29599447 TI - High-resolution GPS tracking reveals sex differences in migratory behaviour and stopover habitat use in the Lesser Black-backed Gull Larus fuscus. AB - Sex-, size- or age-dependent variation in migration strategies in birds is generally expected to reflect differences in competitive abilities. Theoretical and empirical studies thereby focus on differences in wintering areas, by which individuals may benefit from avoiding food competition during winter or ensuring an early return and access to prime nesting sites in spring. Here, we use GPS tracking to assess sex- and size-related variation in the spatial behaviour of adult Lesser Black-backed Gulls (Larus fuscus) throughout their annual cycle. We did not find sex- or size-dependent differences in wintering area or the timing of spring migration. Instead, sexual differences occurred prior to, and during, autumn migration, when females strongly focussed on agricultural areas. Females exhibited a more protracted autumn migration strategy, hence spent more time on stopover sites and arrived 15 days later at their wintering areas, than males. This shift in habitat use and protracted autumn migration coincided with the timing of moult, which overlaps with chick rearing and migration. Our results suggest that this overlap between energy-demanding activities may lead females to perform a more prolonged autumn migration, which results in spatiotemporal differences in foraging habitat use between the sexes. PMID- 29599449 TI - Implications of TERT promoter mutations and telomerase activity in urothelial carcinogenesis. AB - Telomerase activity imparts eukaryotic cells with unlimited proliferation capacity, one of the cancer hallmarks. Over 90% of human urothelial carcinoma of the bladder (UCB) tumours are positive for telomerase activity. Telomerase activation can occur through several mechanisms. Mutations in the core promoter region of the human telomerase reverse transcriptase gene (TERT) cause telomerase reactivation in 60-80% of UCBs, whereas the prevalence of these mutations is lower in urothelial cancers of other origins. TERT promoter mutations are the most frequent genetic alteration across all stages of UCB, indicating a strong selection pressure during neoplastic transformation. TERT promoter mutations could arise during regeneration of normal urothelium and, owing to consequential telomerase reactivation, might be the basis of UCB initiation, which represents a new model of urothelial cancer origination. In the future, TERT promoter mutations and telomerase activity might have diagnostic and therapeutic applications in UCB. PMID- 29599448 TI - RodZ modulates geometric localization of the bacterial actin MreB to regulate cell shape. AB - In the rod-shaped bacterium Escherichia coli, the actin-like protein MreB localizes in a curvature-dependent manner and spatially coordinates cell-wall insertion to maintain cell shape, although the molecular mechanism by which cell width is regulated remains unknown. Here we demonstrate that the membrane protein RodZ regulates the biophysical properties of MreB and alters the spatial organization of E. coli cell-wall growth. The relative expression levels of MreB and RodZ change in a manner commensurate with variations in growth rate and cell width, and RodZ systematically alters the curvature-based localization of MreB and cell width in a concentration-dependent manner. We identify MreB mutants that alter the bending properties of MreB filaments in molecular dynamics simulations similar to RodZ binding, and show that these mutants rescue rod-like shape in the absence of RodZ alone or in combination with wild-type MreB. Thus, E. coli can control its shape and dimensions by differentially regulating RodZ and MreB to alter the patterning of cell-wall insertion, highlighting the rich regulatory landscape of cytoskeletal molecular biophysics. PMID- 29599450 TI - Application of biosurfactant from Bacillus subtilis C9 for controlling cladoceran grazers in algal cultivation systems. AB - Open algal cultivation platforms often suffer crop losses to herbivorous grazers that have potential to devastate biomass production within a few days. While a number of studies suggest synthetic chemicals as control agents for voracious algal grazers, environmental and safety concerns associated with the use of these chemicals encourage the exploration of alternative biological control agents. We hereby propose the application of a biosurfactant produced by Bacillus subtilis C9 (referred to as C9-biosurfactant) for controlling cladoceran grazers commonly found in algal cultivation systems. The results indicated that C9-biosurfactant completely eradicated Daphnia pulex and Moina macrocopa within 24 hours when concentrations were equal to or exceeded 6 mg/L. Moreover, supplying C9 biosurfactant into the cultures of selected algal species with and without cladoceran grazers indicated no adverse effect of C9-biosurfactant on the growth and lipid productivity of algal crops, while cladocerans were selectively controlled by C9-biosurfactant even under the presence of their prey. These results thus indicate that C9-biosurfactant could be an effective biocontrol agent for cladoceran grazers at industrial algal cultivation. PMID- 29599451 TI - Supervised Learning Classifiers for Electrical Impedance-based Bladder State Detection. AB - Urinary Incontinence affects over 200 million people worldwide, severely impacting the quality of life of individuals. Bladder state detection technology has the potential to improve the lives of people with urinary incontinence by alerting the user before voiding occurs. To this end, the objective of this study is to investigate the feasibility of using supervised machine learning classifiers to determine the bladder state of 'full' or 'not full' from electrical impedance measurements. Electrical impedance data was obtained from computational models and a realistic experimental pelvic phantom. Multiple datasets with increasing complexity were formed for varying noise levels in simulation. 10-Fold testing was performed on each dataset to classify 'full' and 'not full' bladder states, including phantom measurement data. Support vector machines and k-Nearest-Neighbours classifiers were compared in terms of accuracy, sensitivity, and specificity. The minimum and maximum accuracies across all datasets were 73.16% and 100%, respectively. Factors that contributed most to misclassification were the noise level and bladder volumes near the threshold of 'full' or 'not full'. This paper represents the first study to use machine learning for bladder state detection with electrical impedance measurements. The results show promise for impedance-based bladder state detection to support those living with urinary incontinence. PMID- 29599452 TI - Direct antiviral properties of TLR ligands against HBV replication in immune competent hepatocytes. AB - Current therapies for chronic hepatitis B virus (HBV) infections are effective at decreasing the viral load in serum, but do not lead to viral eradication. Recent studies highlighted the therapeutic or "adjuvant" potential of immune-modulators. Our aim was to explore the direct anti-HBV effect of Toll-Like-Receptors (TLR) agonists in hepatocytes. HBV-infected primary human hepatocytes (PHH) or differentiated HepaRG cells (dHepaRG) were treated with various TLR agonists. Amongst all TLR ligands tested, Pam3CSK4 (TLR1/2-ligand) and poly(I:C)-(HMW) (TLR3/MDA5-ligand) were the best at reducing all HBV parameters. No or little viral rebound was observed after treatment arrest, implying a long-lasting effect on cccDNA. We also tested Riboxxol that features improved TLR3 specificity compared to poly(I:C)-(HMW). This agonist demonstrated a potent antiviral effect in HBV-infected PHH. Whereas, poly(I:C)-(HMW) and Pam3CSK4 mainly induced the expression of classical genes from the interferon or NF-kappaB pathway respectively, Riboxxol had a mixed phenotype. Moreover, TLR2 and TLR3 ligands can activate hepatocytes and immune cells, as demonstrated by antiviral cytokines produced by stimulated hepatocytes and peripheral blood mononuclear cells. In conclusion, our data highlight the potential of innate immunity activation in the direct control of HBV replication in hepatocytes, and support the development of TLR-based antiviral strategies. PMID- 29599454 TI - A neutrophil motility assay for early diagnosis of sepsis. PMID- 29599453 TI - Functional cyclophilin D moderates platelet adhesion, but enhances the lytic resistance of fibrin. AB - In the course of thrombosis, platelets are exposed to a variety of activating stimuli classified as 'strong' (e.g. thrombin and collagen) or 'mild' (e.g. ADP). In response, activated platelets adhere to injured vasculature, aggregate, and stabilise the three-dimensional fibrin scaffold of the expanding thrombus. Since 'strong' stimuli also induce opening of the mitochondrial permeability transition pore (MPTP) in platelets, the MPTP-enhancer Cyclophilin D (CypD) has been suggested as a critical pharmacological target to influence thrombosis. However, it is poorly understood what role CypD plays in the platelet response to 'mild' stimuli which act independently of MPTP. Furthermore, it is unknown how CypD influences platelet-driven clot stabilisation against enzymatic breakdown (fibrinolysis). Here we show that treatment of human platelets with Cyclosporine A (a cyclophilin-inhibitor) boosts ADP-induced adhesion and aggregation, while genetic ablation of CypD in murine platelets enhances adhesion but not aggregation. We also report that platelets lacking CypD preserve their integrity in a fibrin environment, and lose their ability to render clots resistant against fibrinolysis. Our results indicate that CypD has opposing haemostatic roles depending on the stimulus and stage of platelet activation, warranting a careful design of any antithrombotic strategy targeting CypD. PMID- 29599455 TI - Comprehensive characterization of glutamine synthetase-mediated selection for the establishment of recombinant CHO cells producing monoclonal antibodies. AB - To characterize a glutamine synthetase (GS)-based selection system, monoclonal antibody (mAb) producing recombinant CHO cell clones were generated by a single round of selection at various methionine sulfoximine (MSX) concentrations (0, 25, and 50 MUM) using two different host cell lines (CHO-K1 and GS-knockout CHO). Regardless of the host cell lines used, the clones selected at 50 MUM MSX had the lowest average specific growth rate and the highest average specific production rates of toxic metabolic wastes, lactate and ammonia. Unlike CHO-K1, high producing clones could be generated in the absence of MSX using GS-knockout CHO with an improved selection stringency. Regardless of the host cell lines used, the clones selected at various MSX concentrations showed no significant difference in the GS, heavy chain, and light chain gene copies (P > 0.05). Furthermore, there was no correlation between the specific mAb productivity and these three gene copies (R2 <= 0.012). Taken together, GS-mediated gene amplification does not occur in a single round of selection at a MSX concentration up to 50 MUM. The use of the GS-knockout CHO host cell line facilitates the rapid generation of high producing clones with reduced production of lactate and ammonia in the absence of MSX. PMID- 29599456 TI - To grow, or not to grow. PMID- 29599458 TI - CRISPR-based genomic tools for the manipulation of genetically intractable microorganisms. AB - Genetic manipulation of microorganisms has been crucial in understanding their biology, yet for many microbial species, robust tools for comprehensive genetic analysis were lacking until the advent of CRISPR-Cas-based gene editing techniques. In this Progress article, we discuss advances in CRISPR-based techniques for the genetic analysis of genetically intractable microorganisms, with an emphasis on mycobacteria, fungi and parasites. We discuss how CRISPR based analyses in these organisms have enabled the discovery of novel gene functions, the investigation of genetic interaction networks and the identification of virulence factors. PMID- 29599457 TI - Streptococcus pneumoniae: transmission, colonization and invasion. AB - Streptococcus pneumoniae has a complex relationship with its obligate human host. On the one hand, the pneumococci are highly adapted commensals, and their main reservoir on the mucosal surface of the upper airways of carriers enables transmission. On the other hand, they can cause severe disease when bacterial and host factors allow them to invade essentially sterile sites, such as the middle ear spaces, lungs, bloodstream and meninges. Transmission, colonization and invasion depend on the remarkable ability of S. pneumoniae to evade or take advantage of the host inflammatory and immune responses. The different stages of pneumococcal carriage and disease have been investigated in detail in animal models and, more recently, in experimental human infection. Furthermore, widespread vaccination and the resulting immune pressure have shed light on pneumococcal population dynamics and pathogenesis. Here, we review the mechanistic insights provided by these studies on the multiple and varied interactions of the pneumococcus and its host. PMID- 29599459 TI - The social network of microorganisms - how auxotrophies shape complex communities. AB - Microorganisms engage in complex interactions with other organisms and their environment. Recent studies have shown that these interactions are not limited to the exchange of electron donors. Most microorganisms are auxotrophs, thus relying on external nutrients for growth, including the exchange of amino acids and vitamins. Currently, we lack a deeper understanding of auxotrophies in microorganisms and how nutrient requirements differ between different strains and different environments. In this Opinion article, we describe how the study of auxotrophies and nutrient requirements among members of complex communities will enable new insights into community composition and assembly. Understanding this complex network over space and time is crucial for developing strategies to interrogate and shape microbial communities. PMID- 29599460 TI - High-speed and on-chip graphene blackbody emitters for optical communications by remote heat transfer. AB - High-speed light emitters integrated on silicon chips can enable novel architectures for silicon-based optoelectronics, such as on-chip optical interconnects, and silicon photonics. However, conventional light sources based on compound semiconductors face major challenges for their integration with a silicon-based platform because of their difficulty of direct growth on a silicon substrate. Here we report ultra-high-speed (100-ps response time), highly integrated graphene-based on-silicon-chip blackbody emitters in the near-infrared region including telecommunication wavelength. Their emission responses are strongly affected by the graphene contact with the substrate depending on the number of graphene layers. The ultra-high-speed emission can be understood by remote quantum thermal transport via surface polar phonons of the substrates. We demonstrated real-time optical communications, integrated two-dimensional array emitters, capped emitters operable in air, and the direct coupling of optical fibers to the emitters. These emitters can open new routes to on-Si-chip, small footprint, and high-speed emitters for highly integrated optoelectronics and silicon photonics. PMID- 29599461 TI - Using human brain activity to guide machine learning. AB - Machine learning is a field of computer science that builds algorithms that learn. In many cases, machine learning algorithms are used to recreate a human ability like adding a caption to a photo, driving a car, or playing a game. While the human brain has long served as a source of inspiration for machine learning, little effort has been made to directly use data collected from working brains as a guide for machine learning algorithms. Here we demonstrate a new paradigm of "neurally-weighted" machine learning, which takes fMRI measurements of human brain activity from subjects viewing images, and infuses these data into the training process of an object recognition learning algorithm to make it more consistent with the human brain. After training, these neurally-weighted classifiers are able to classify images without requiring any additional neural data. We show that our neural-weighting approach can lead to large performance gains when used with traditional machine vision features, as well as to significant improvements with already high-performing convolutional neural network features. The effectiveness of this approach points to a path forward for a new class of hybrid machine learning algorithms which take both inspiration and direct constraints from neuronal data. PMID- 29599462 TI - Recurrence of task-related electroencephalographic activity during post-training quiet rest and sleep. AB - Offline reactivation of task-related neural activity has been demonstrated in animals but is difficult to directly observe in humans. We sought to identify potential electroencephalographic (EEG) markers of offline memory processing in human subjects by identifying a set of characteristic EEG topographies ("microstates") that occurred as subjects learned to navigate a virtual maze. We hypothesized that these task-related microstates would appear during post-task periods of rest and sleep. In agreement with this hypothesis, we found that one task-related microstate was increased in post-training rest and sleep compared to baseline rest, selectively for subjects who actively learned the maze, and not in subjects performing a non-learning control task. Source modeling showed that this microstate was produced by activity in temporal and parietal networks, which are known to be involved in spatial navigation. For subjects who napped after training, the increase in this task-related microstate predicted the magnitude of subsequent change in performance. Our findings demonstrate that task-related EEG patterns re-emerge during post-training rest and sleep. PMID- 29599463 TI - An explanation for the low proportion of tuberculosis that results from transmission between household and known social contacts. AB - We currently have little idea where Mycobacterium tuberculosis (Mtb) transmission occurs in high incidence settings. Molecular studies suggest that only around 8 19% of transmission to adults occurs within-household, or between known social contacts. This contrasts with findings from social-contact studies, which show that substantial proportions of contact time occur in households, workplaces and schools. A mathematical model of social-contact behaviour and Mtb transmission was developed, incorporating variation in susceptibility and infectiousness. Three types of contact were simulated: household, repeated (individuals outside household contacted repeatedly with daily-monthly frequency) and non-repeated. The model was parameterised using data from Cape Town, South Africa, on mean and variance in contact numbers and contact durations, by contact type, and fitted to an estimate of overdispersion in numbers of secondary cases ('superspreading') in Cape Town. Household, repeated, and non-repeated contacts contributed 36%, 13%, and 51% of contact time, and 13%, 8%, and 79% of disease, respectively. Results suggest contact saturation, exacerbated by long disease durations and superspreading, cause the high proportion of transmission between non-repeated contacts. Household and social-contact tracing is therefore unlikely to reach most tuberculosis cases. A better understanding of transmission locations, and methods to identify superspreaders, are urgently required to improve tuberculosis prevention strategies. PMID- 29599464 TI - Real-time distribution of pelagic fish: combining hydroacoustics, GIS and spatial modelling at a fine spatial scale. AB - Understanding spatial distribution of organisms in heterogeneous environment remains one of the chief issues in ecology. Spatial organization of freshwater fish was investigated predominantly on large-scale, neglecting important local conditions and ecological processes. However, small-scale processes are of an essential importance for individual habitat preferences and hence structuring trophic cascades and species coexistence. In this work, we analysed the real-time spatial distribution of pelagic freshwater fish in the Rimov Reservoir (Czechia) observed by hydroacoustics in relation to important environmental predictors during 48 hours at 3-h interval. Effect of diurnal cycle was revealed of highest significance in all spatial models with inverse trends between fish distribution and predictors in day and night in general. Our findings highlighted daytime pelagic fish distribution as highly aggregated, with general fish preferences for central, deep and highly illuminated areas, whereas nighttime distribution was more disperse and fish preferred nearshore steep sloped areas with higher depth. This turnover suggests prominent movements of significant part of fish assemblage between pelagic and nearshore areas on a diel basis. In conclusion, hydroacoustics, GIS and spatial modelling proved as valuable tool for predicting local fish distribution and elucidate its drivers, which has far reaching implications for understanding freshwater ecosystem functioning. PMID- 29599465 TI - Evaluation of Screened Lignin-degrading Fungi for the Biological Pretreatment of Corn Stover. AB - The biological pretreatment of lignocellulosic biomass is a low-cost and eco friendly method for facilitating enzymatic hydrolysis. In this study, strains with lignin depletion capability were screened using a high-throughput screening method. Sixty-three strains were screened out and Myrothecium verrucaria secreted three lignin-degrading enzymes simultaneously during the bio-pretreatment process. The activity levels of laccase, lignin peroxidase and manganese peroxidase were 6.61, 0.78 and 1.31 U g-1 dry biomass. The content of lignin in corn stover decreased by 42.30% after bio-pretreatment, and the conversion rate increased by 123.84% during the subsequent saccharification process in comparison with the untreated corn stover. Furthermore, the effects of bio-pretreatment on the structure of corn stover were presented using a scanning electron microscope (SEM), Brunauer-Emmet-Teller (BET), X-ray diffractometer (XRD) and Fourier transform infrared spectroscopy (FTIR). The results showed that M.V. is a promising lignin-degrading fungus. This research demonstrated an efficient pretreatment approach for enhancing the enzymatic saccharification of corn stover. PMID- 29599466 TI - A high-brightness large-diameter graphene coated point cathode field emission electron source. AB - There have been several long-standing problems of cold field emission sources for electron microscopy and lithography that have prevented their widespread use, such as their inherent ultrahigh vacuum condition requirement (<10-9 torr), relatively poor current stability and rapid emission decay. This paper presents a cold field emission electron source which overcomes these problems based upon using a graphene-coated nickel point cathode. Preliminary experiments demonstrate that it provides stable emission for relatively large tip diameters (micron sizes), can operate in high vacuum conditions (>10-8 torr) and has an ultralow work function value of 1.10 +/- 0.07 eV. It has an estimated reduced brightness value of 1.46 * 109 A m-2 sr-1 V-1 for cathode tip-radius of 170 nm and the measured energy spread ranges from 0.246 eV to 0.420 eV for a tip radii range of 260 nm to 500 nm, which is comparable to state-of-the-art conventional cold field emission sources. PMID- 29599468 TI - Enhanced Ti0.84Ta0.16N diffusion barriers, grown by a hybrid sputtering technique with no substrate heating, between Si(001) wafers and Cu overlayers. AB - We compare the performance of conventional DC magnetron sputter-deposited (DCMS) TiN diffusion barriers between Cu overlayers and Si(001) substrates with Ti0.84Ta0.16N barriers grown by hybrid DCMS/high-power impulse magnetron sputtering (HiPIMS) with substrate bias synchronized to the metal-rich portion of each pulse. DCMS power is applied to a Ti target, and HiPIMS applied to Ta. No external substrate heating is used in either the DCMS or hybrid DCMS/HiPIMS process in order to meet future industrial thermal-budget requirements. Barrier efficiency in inhibiting Cu diffusion into Si(001) while annealing for 1 hour at temperatures between 700 and 900 degrees C is investigated using scanning electron microscopy, X-ray diffraction, four-point-probe sheet resistance measurements, transmission electron microscopy, and energy-dispersive X-ray spectroscopy profiling. Ti0.84Ta0.16N barriers are shown to prevent large-scale Cu diffusion at temperatures up to 900 degrees C, while conventional TiN barriers fail at <=700 degrees C. The improved performance of the Ti0.84Ta0.16N barrier is due to film densification resulting from HiPIMS pulsed irradiation of the growing film with synchronized Ta ions. The heavy ion bombardment dynamically enhances near-surface atomic mixing during barrier-layer deposition.

AB - Diabetic Retinopathy (DR) is an extremely severe and common degenerative disease. The purpose of this study was to quantify the relationship between various parameters including the Foveal Avascular Zone (FAZ) morphology, retinal layer thickness, and retinal hemodynamic properties in healthy controls and patients with diabetes mellitus (DM) with and with no mild DR (MDR) using Spectral-Domain Optical Coherence Tomography (Spectralis SDOCT, Heidelberg Engineering GmbH, Germany) and the Retinal Function Imager (Optical Imaging, Ltd., Rehovot, Israel). Our results showed a higher FAZ area and diameter in MDR patients. Blood flow analysis also showed that there is a significantly smaller venous blood flow velocity in MDR patients. Also, a significant difference in roundness was observed between DM and MDR groups supporting the development of asymmetrical FAZ expansion with worsening DR. Our results suggest a potential anisotropy in the mechanical properties of the diabetic retina with no retinopathy that may trigger the FAZ elongation in a preferred direction resulting in either thinning or thickening of intraretinal layers in the inner and outer segments of the retina as a result of autoregulation. A detailed understanding of these relationships may facilitate earlier detection of DR, allowing for preservation of vision and better clinical outcomes. PMID- 29599469 TI - Scalable synthesis enabling multilevel bio-evaluations of natural products for discovery of lead compounds. AB - Challenges in the development of anti-cancer chemotherapeutics continue to exist, particularly with respect to adverse effects and development of resistance, underlining the need for novel drugs with good safety profiles. Natural products have proven to be a fertile ground for exploitation, and development of anti cancer drugs from structurally complex natural products holds promise. Unfortunately, this approach is often hindered by low isolation yields and limited information from preliminary cell-based assays. Here we report a concise and scalable synthesis of a series of low-abundance Isodon diterpenoids (a large class of natural products with over 1000 members isolated from the herbs of genus Isodon, which are well-known folk medicines for the treatment of inflammation and cancer), including eriocalyxin B, neolaxiflorin L and xerophilusin I. These scalable syntheses enable multilevel bio-evaluation of the natural products, in which we identify neolaxiflorin L as a promising anti-cancer drug candidate. PMID- 29599470 TI - An advanced human in vitro co-culture model for translocation studies across the placental barrier. AB - Although various drugs, environmental pollutants and nanoparticles (NP) can cross the human placental barrier and may harm the developing fetus, knowledge on predictive placental transfer rates and the underlying transport pathways is mostly lacking. Current available in vitro placental transfer models are often inappropriate for translocation studies of macromolecules or NPs and do not consider barrier function of placental endothelial cells (EC). Therefore, we developed a human placental in vitro co-culture transfer model with tight layers of trophoblasts (BeWo b30) and placental microvascular ECs (HPEC-A2) on a low absorbing, 3 um porous membrane. Translocation studies with four model substances and two polystyrene (PS) NPs across the individual and co-culture layers revealed that for most of these compounds, the trophoblast and the EC layer both demonstrate similar, but not additive, retention capacity. Only the paracellular marker Na-F was substantially more retained by the BeWo layer. Furthermore, simple shaking, which is often applied to mimic placental perfusion, did not alter translocation kinetics compared to static exposure. In conclusion, we developed a novel placental co-culture model, which provides predictive values for translocation of a broad variety of molecules and NPs and enables valuable mechanistic investigations on cell type-specific placental barrier function. PMID- 29599471 TI - Activation of Eosinophils and Mast Cells in Functional Dyspepsia: an Ultrastructural Evaluation. AB - We recently identified mucosal mast cell and eosinophil hyperplasia in association with a duodenal impaired barrier function in functional dyspepsia (FD). We aimed to further describe the implication of these immune cells by assessing their activation state at the ultrastructural level and by evaluating the association between impaired epithelial integrity and immune activation. Duodenal biopsies were obtained from 24 FD patients and 37 healthy controls. The ultrastructure of mast cells and eosinophils was analyzed by transmission electron microscopy. Transepithelial electrical resistance and paracellular permeability were measured to evaluate epithelial barrier function. The type of degranulation in eosinophils and mast cells was piecemeal. Eosinophils displayed higher degree of degranulation in FD patients than in controls (p < 0.0001). Quantification revealed a decreased granular density in eosinophils of FD patients (p < 0.0001). The degree of degranulation in mast cells was similar in both groups. However, a more heterogeneous profile was found in the FD group (p < 0.0001). No association between epithelial integrity and the number and activation state of mucosal eosinophils and mast cells was found. We demonstrated ultrastructural changes in degranulation state of eosinophils and mast cells, suggesting that eosinophil and mast cell activation play a role in the pathophysiology of FD. PMID- 29599472 TI - Examination of Csr regulatory circuitry using epistasis analysis with RNA-seq (Epi-seq) confirms that CsrD affects gene expression via CsrA, CsrB and CsrC. AB - The Csr global regulatory system coordinates gene expression in response to metabolic status. This system utilizes the RNA binding protein CsrA to regulate gene expression by binding to transcripts of structural and regulatory genes, thus affecting their structure, stability, translation, and/or transcription elongation. CsrA activity is controlled by sRNAs, CsrB and CsrC, which sequester CsrA away from other transcripts. CsrB/C levels are partly determined by their rates of turnover, which requires CsrD to render them susceptible to RNase E cleavage. Previous epistasis analysis suggested that CsrD affects gene expression through the other Csr components, CsrB/C and CsrA. However, those conclusions were based on a limited analysis of reporters. Here, we reassessed the global behavior of the Csr circuitry using epistasis analysis with RNA seq (Epi-seq). Because CsrD effects on mRNA levels were entirely lost in the csrA mutant and largely eliminated in a csrB/C mutant under our experimental conditions, while the majority of CsrA effects persisted in the absence of csrD, the original model accounts for the global behavior of the Csr system. Our present results also reflect a more nuanced role of CsrA as terminal regulator of the Csr system than has been recognized. PMID- 29599473 TI - Epigallocatechin-3-gallate alleviates bladder overactivity in a rat model with metabolic syndrome and ovarian hormone deficiency through mitochondria apoptosis pathways. AB - Metabolic syndrome (MetS) and ovarian hormone deficiency could affect bladder storage dysfunction. Epigallocatechin-3-gallate (EGCG), a polyphenolic compound in green tea, has been shown to protect against ovarian hormone deficiency induced overactive bladder (OAB). The present study investigated oxidative stress induced by MetS and bilateral ovariectomy (OVX), and elucidated the mechanism underlying the protective effect of EGCG (10 umol/kg/day) on bladder overactivity. Rats were fed with high fat high sugar (HFHS) diet to induce MetS and received ovariectomy surgery to deprive ovarian hormone. By dieting with HFHS for 6 months, rats developed MetS and OAB. MetS + OVX deteriorated bladder storage dysfunction more profound than MetS alone. MetS and MetS + OVX rats showed over-expression of inflammatory and fibrosis markers (1.7~3.8-fold of control). EGCG pretreatment alleviated storage dysfunction, and protected the bladders from MetS and OVX - induced interstitial fibrosis changes. Moreover, OVX exacerbated MetS related bladder apoptosis (2.3~4.5-fold of control; 1.8~2.6-fold of Mets group), enhances oxidative stress markers (3.6~4.3-fold of control; 1.8~2.2-fold of Mets group) and mitochondrial enzyme complexes subunits (1.8~3.7 fold of control; 1.5~3.4-fold of Mets group). EGCG pretreatment alleviated bladder apoptosis, attenuated oxidative stress, and reduced the mitochondrial and endoplasmic reticulum apoptotic signals. In conclusions, HFHS feeding and ovarian hormone deficiency enhances the generation of oxidative stress mediated through mitochondrial pathway. EGCG reduced the generation of oxidative stress and lessened bladder overactivity. PMID- 29599475 TI - Precision oncology in non-small-cell lung cancer: opportunities and challenges. PMID- 29599474 TI - Outer membrane vesicles from beta-lactam-resistant Escherichia coli enable the survival of beta-lactam-susceptible E. coli in the presence of beta-lactam antibiotics. AB - Outer membrane vesicles (OMVs) containing various bacterial compounds are released from mainly gram-negative bacteria. Secreted OMVs play important roles in the ability of a bacterium to defend itself, and thus contribute to the survival of bacteria in a community. In this study, we collected OMVs from beta lactam antibiotic-resistant Escherichia coli established by conjugation assay and the parental beta-lactam antibiotic-susceptible strain, and performed comparative proteomic analysis to examine whether these OMVs carried beta-lactam-resistant compounds. We also investigated whether both types of OMVs could protect susceptible cells from beta-lactam-induced death and/or directly degrade beta lactam antibiotics. Several proteins that can be involved in degrading beta lactam antibiotics were more abundant in OMVs from beta-lactam-resistant E. coli, and thus OMVs from beta-lactam resistant E. coli could directly and dose dependently degrade beta-lactam antibiotics and fully rescue beta-lactam susceptible E. coli and other bacterial species from beta-lactam antibiotic induced growth inhibition. Taken together, present study demonstrate that OMVs from beta-lactam-resistant E. coli play important roles in survival of antibiotic susceptible bacteria against beta-lactam antibiotics. This finding may pave the way for new efforts to combat the current global spread of antibiotic resistances, which is considered to be a significant public health threat. PMID- 29599476 TI - The emerging clinical relevance of genomics in cancer medicine. AB - The combination of next-generation sequencing and advanced computational data analysis approaches has revolutionized our understanding of the genomic underpinnings of cancer development and progression. The coincident development of targeted small molecule and antibody-based therapies that target a cancer's genomic dependencies has fuelled the transition of genomic assays into clinical use in patients with cancer. Beyond the identification of individual targetable alterations, genomic methods can gauge mutational load, which might predict a therapeutic response to immune-checkpoint inhibitors or identify cancer-specific proteins that inform the design of personalized anticancer vaccines. Emerging clinical applications of cancer genomics include monitoring treatment responses and characterizing mechanisms of resistance. The increasing relevance of genomics to clinical cancer care also highlights several considerable challenges, including the need to promote equal access to genomic testing. PMID- 29599477 TI - The world's largest High Arctic lake responds rapidly to climate warming. AB - Using a whole-watershed approach and a combination of historical, contemporary, modeled and paleolimnological datasets, we show that the High Arctic's largest lake by volume (Lake Hazen) has succumbed to climate warming with only a ~1 degrees C relative increase in summer air temperatures. This warming deepened the soil active layer and triggered large mass losses from the watershed's glaciers, resulting in a ~10 times increase in delivery of glacial meltwaters, sediment, organic carbon and legacy contaminants to Lake Hazen, a >70% decrease in lake water residence time, and near certainty of summer ice-free conditions. Concomitantly, the community assemblage of diatom primary producers in the lake shifted dramatically with declining ice cover, from shoreline benthic to open water planktonic species, and the physiological condition of the only fish species in the lake, Arctic Char, declined significantly. Collectively, these changes place Lake Hazen in a biogeochemical, limnological and ecological regime unprecedented within the past ~300 years. PMID- 29599479 TI - Boson peak, heterogeneity and intermediate-range order in binary SiO2-Al2O3 glasses. AB - In binary aluminosilicate liquids and glasses, heterogeneity on intermediate length scale is a crucial factor for optical fiber performance, determining the lower limit of optical attenuation and Rayleigh scattering, but also clustering and precipitation of optically active dopants, for example, in the fabrication of high-power laser gain media. Here, we consider the low-frequency vibrational modes of such materials for assessing structural heterogeneity on molecular scale. We determine the vibrational density of states VDoS g(omega) using low temperature heat capacity data. From correlation with low-frequency Raman spectroscopy, we obtain the Raman coupling coefficient. Both experiments allow for the extraction of the average dynamic correlation length as a function of alumina content. We find that this value decreases from about 3.9 nm to 3.3 nm when mildly increasing the alumina content from zero (vitreous silica) to 7 mol%. At the same time, the average inter-particle distance increases slightly due to the presence of oxygen tricluster species. In accordance with Loewensteinian dynamics, this proves that mild alumina doping increases structural homogeneity on molecular scale. PMID- 29599478 TI - Chronic nicotinamide riboside supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults. AB - Nicotinamide adenine dinucleotide (NAD+) has emerged as a critical co-substrate for enzymes involved in the beneficial effects of regular calorie restriction on healthspan. As such, the use of NAD+ precursors to augment NAD+ bioavailability has been proposed as a strategy for improving cardiovascular and other physiological functions with aging in humans. Here we provide the evidence in a 2 * 6-week randomized, double-blind, placebo-controlled, crossover clinical trial that chronic supplementation with the NAD+ precursor vitamin, nicotinamide riboside (NR), is well tolerated and effectively stimulates NAD+ metabolism in healthy middle-aged and older adults. Our results also provide initial insight into the effects of chronic NR supplementation on physiological function in humans, and suggest that, in particular, future clinical trials should further assess the potential benefits of NR for reducing blood pressure and arterial stiffness in this group. PMID- 29599480 TI - Fungal spore diversity reflects substrate-specific deposition challenges. AB - Sexual spores are important for the dispersal and population dynamics of fungi. They show remarkable morphological diversity, but the underlying forces driving spore evolution are poorly known. We investigated whether trophic status and substrate associations are associated with morphology in 787 macrofungal genera. We show that both spore size and ornamentation are associated with trophic specialization, so that large and ornamented spores are more probable in ectomycorrhizal than in saprotrophic genera. This suggests that spore ornamentation facilitates attachment to arthropod vectors, which ectomycorrhizal species may need to reach lower soil layers. Elongated spore shapes are more common in saprotrophic taxa, and genera associated with above ground substrates are more likely to have allantoid (curved elongated) spores, probably to lower the risk of wash out by precipitation. Overall, our results suggest that safe arrival on specific substrates is a more important driver of evolution in spore morphology than dispersal per se. PMID- 29599481 TI - Developing transmission line equations of oxygen transport for predicting oxygen distribution in the arterial system. AB - The oxygen content in the arterial system plays a significant role in determining the physiological status of a human body. Understanding the oxygen concentration distribution in the arterial system is beneficial for the prevention and intervention of vascular disease. However, the oxygen concentration in the arteries could not be noninvasively monitored in clinical research. Although the oxygen concentration distribution in a vessel could be obtained from a three dimensional (3D) numerical simulation of blood flow coupled with oxygen transport, a 3D numerical simulation of the systemic arterial tree is complicated and requires considerable computational resources and time. However, the lumped parameter model of oxygen transport derived from transmission line equations of oxygen transport requires fewer computational resources and less time to numerically predict the oxygen concentration distribution in the systemic arterial tree. In this study, transmission line equations of oxygen transport are developed according to the theory of oxygen transport in the vessel, and fluid transmission line equations are used as the theoretical reference for the development. The transmission line equations of oxygen transport could also be regarded as the theoretical basis for developing lumped parameter models of other substances in blood. PMID- 29599482 TI - The Notch inhibitor cowanin accelerates nicastrin degradation. AB - Aberrant activation of Notch signaling contributes to the pathogenesis of several different types of cancer, and Notch pathway inhibitors may have significant therapeutic potential. Using a unique cell-based assay system, we isolated twelve compounds, including one new natural product from Garcinia speciosa, that inhibit the Notch signaling pathway. HES1 and HES5 are target genes of the Notch cascade, and compound 2, referred to as cowanin, decreased the protein levels of HES1 and HES5 in assay cells. Furthermore, cowanin (2) showed potent cytotoxicity against human leukemic HPB-ALL cells. The Notch signaling inhibitory activity of cowanin (2) is linked to the increased degradation of nicastrin, which is one of the components of the gamma-secretase complex. To the best of our knowledge, this is the first example of a compound with Notch pathway inhibitory activity mediated by nicastrin degradation. PMID- 29599483 TI - Identification of The Aberrantly Expressed LncRNAs in Hepatocellular Carcinoma: A Bioinformatics Analysis Based on RNA-sequencing. AB - Hepatocellular carcinoma (HCC) is one of the most prevalent subtypes of liver cancer worldwide. LncRNAs have been demonstrated to be associated with the progression of HCC, but a systematic identification and characterization of their clinical roles and molecular mechanisms in HCC has not been conducted. In this study, the aberrantly expressed lncRNAs in HCC tissues were analyzed based on TCGA RNA-seq data. 1162 lncRNAs were found to be aberrantly expressed in HCC tissues, including 232 down-regulated lncRNAs and 930 up-regulated lncRNAs. The top 5 lncRNAs with the highest diagnostic accuracy were further analyzed to evaluate their clinical value and potential mechanism in HCC. Kaplan-Meier curves showed that higher expressions of DDX11-AS1 and AC092171.4 were in correlation with poorer survival in HCC patients. Significant difference was also observed when comparing the expression levels of DDX11-AS1 and SFTA1P in different clinical parameters (p < 0.05). GO analysis showed that genes regulated by the 5 lncRNAs were enriched in certain pathways, such as PI3K pathway. Moreover, GSEA analysis on the expression of DDX11-AS1 showed that DDX11-AS1 affected the gene expressions involved in HCC proliferation, differentiation and cell cycle, indicating an essential role of DDX11-AS1 in hepatocarcinogenesis. PMID- 29599484 TI - Prophylactic ketamine alters nucleotide and neurotransmitter metabolism in brain and plasma following stress. AB - Recently, we have shown that ketamine given prior to stress exposure protects against the development of depressive-like behavior in mice. These data suggest that it may be possible to prevent the induction of affective disorders before they develop by administering prophylactic pharmaceuticals, a relatively nascent and unexplored strategy for psychiatry. Here, we performed metabolomics analysis of brain and plasma following prophylactic ketamine treatment in order to identify markers of stress resilience enhancement. We administered prophylactic ketamine in mice to buffer against fear expression. Following behavioral analyses, untargeted metabolomic profiling was performed on both hemispheres of the prefrontal cortex (PFC) and the hippocampus (HPC), and plasma. We found that prophylactic ketamine attenuated learned fear. Eight metabolites were changed in the PFC and HPC upon ketamine treatment. Purine and pyrimidine metabolism were most significantly changed in the HPC, PFC, and, interestingly, plasma of mice two weeks after prophylactic administration. Moreover, most precursors to inhibitory neurotransmitters were increased whereas precursors to excitatory neurotransmitters were decreased. Strikingly, these long-term metabolomic changes were not observed when no stressor was administered. Our results suggest that prophylactic treatment differentially affects purine and pyrimidine metabolism and neurotransmission in brain and plasma following stress, which may underlie the long-lasting resilience to stress induced by a single injection of ketamine. These data may provide novel targets for prophylactic development, and indicate an interaction effect of prophylactic ketamine and stress. To our knowledge, this is the first study that identifies metabolomic alterations and biomarker candidates for prophylactic ketamine efficacy in mice. PMID- 29599485 TI - Neurocognitive effects of umami: association with eating behavior and food choice. AB - Free glutamate, a key substance underlying the umami taste of foods, fulfills a number of physiological functions related to energy balance. Previous experimental studies have shown that intake of a broth or soup supplemented with monosodium glutamate (MSG) prior to a meal can decrease appetite and food intake, particularly in women with propensity to overeat and gain weight. In this study, we examined potential neurocognitive mechanisms underlying this effect. We evaluated changes after intake of a chicken broth with or without MSG added (MSG+/MSG-) in a sample of healthy young women. Subjects were assessed with a food-modified computerized inhibitory control task, a buffet meal test with eye tracking, and brain responses during a food choice paradigm evaluated with functional neuroimaging. We found evidence for improvement in key parameters related to inhibitory control following intake of the MSG+ broth, particularly in subjects with high levels of eating disinhibition, who also showed lower intake of saturated fat during the meal. Additionally, consumption of the MSG+ broth led to a reduction of the rate of fixation switches between plates at the meal, and increased engagement of a brain region in the left dorsolateral prefrontal cortex previously associated with successful self-control during dietary decisions. Altogether, these results, while preliminary, suggest potential facilitating effects of glutamate (MSG) on cognitive executive processes that are relevant for the support of healthy eating behaviors and food choice. PMID- 29599487 TI - Baclofen and gastroesophageal reflux disease: seeing the forest through the trees. AB - Baclofen has been shown to decrease reflux events and increase lower esophageal sphincter pressure, yet has never established a clear role in the treatment of gastroesophageal reflux disease (GERD). Lei and colleagues have shown in a recent elegant study that baclofen reduces the frequency and initiation of secondary peristalsis and heightens esophageal sensitivity to capsaicin-mediated stimulation. These findings may help explain both the benefit of baclofen in conditions such as rumination and supragastric belching, as well as the apparent lack of benefit of baclofen and other GABAB agonists in long-term treatment of GERD. PMID- 29599486 TI - USP52 acts as a deubiquitinase and promotes histone chaperone ASF1A stabilization. AB - Histone chaperone ASF1A has been reported to be dysregulated in multiple tumors; however, the underlying molecular mechanism that how the abundance and function of ASF1A are regulated remains unclear. Here we report that ASF1A is physically associated with USP52, which is previously identified as a pseudo-deubiquitinase. Interestingly, we demonstrate that USP52 is a bona fide ubiquitin-specific protease, and USP52 promotes ASF1A deubiquitination and stabilization. USP52 promoted ASF1A stabilization facilitates chromatin assembly and favors cell cycle progression. Additionally, we find that USP52 is overexpressed in breast carcinomas, and its level of expression correlates with that of ASF1A. Moreover, we reveal that impairment of USP52-promoted ASF1A stabilization results in growth arrest of breast cancer cells and sensitizes these cells to DNA damage. Our experiments identify USP52 as a truly protein deubiquitinase, uncover a molecular mechanism of USP52 in chromatin assembly, and reveal a potential role of USP52 in breast carcinogenesis.

PMID- 29599489 TI - Matrix Metalloproteinase Mediated Type I Collagen Degradation is an Independent Predictor of Increased Risk of Acute Myocardial Infarction in Postmenopausal Women. AB - Acute myocardial infarction (AMI) is often underdiagnosed in women. It is therefore of interest to identify biomarkers that indicate increased risk of AMI and thereby help clinicians to have additional focus on the difficult AMI diagnosis. Type I Collagen, a component of the cardiac extracellular matrix, is cleaved by matrix metalloproteinases (MMPs) generating the neo-epitope C1M. We investigated the association between serum-C1M and AMI and evaluated whether C1M is a prognostic marker for outcome following AMI. This study is based on The Prospective Epidemiological Risk Factor (PERF) Study including postmenopausal women. 316 out of 5,450 women developed AMI within the follow-up period (14 years, median). A multivariate Cox analysis assessed association between serum C1M and AMI, and re-infaction or death subsequent to AMI. The risk of AMI increased by 18% (p = 0.03) when serum-C1M was doubled and women in the highest quartile had a 33% increased risk compared to those in the low quartiles (p = 0.025). Serum-C1M was, however not related to reinfarction or death subsequent to AMI. In this study C1M was be an independent risk factor for AMI. Measuring MMP degraded type I collagen could be useful for prediction of increased risk of AMI if replicated in other cohorts. PMID- 29599490 TI - Interaction of Glycolipids with the Macrophage Surface Receptor Mincle - a Systematic Molecular Dynamics Study. AB - Synthetic analogues of mycobacterial trehalose-dimycolate such as trehalose acyl esters have been proposed as novel adjuvants for vaccination. They induce an immune response by binding to the macrophage C-type lectin receptor Mincle. The binding site of trehalose is known, but there is yet only very limited structural information about the binding mode of the acyl esters. Here, we performed a systematic molecular dynamics study of trehalose mono-and diesters with different chain lengths. All acyl chains investigated exhibited a high flexibility and interacted almost exclusively with a hydrophobic groove on Mincle. Despite the limited length of this hydrophobic groove, the distal parts of the longer monoesters can still form additional interactions with this surface region due to their conformational flexibility. In diesters, a certain length of the second acyl chain is required to contact the hydrophobic groove. However, a stable concomitant accommodation of both acyl chains in the groove is hampered by the conformational rigidity of Mincle. Instead, multiple dynamic interaction modes are observed, in which the second acyl chain contributes to binding. This detailed structural information is considered helpful for the future design of more affine ligands that may foster the development of novel adjuvants. PMID- 29599491 TI - The immune contexture of hepatocellular carcinoma predicts clinical outcome. AB - The general relevance of the immune system for cancer development and therapy is increasingly recognized. However and although the immune contexture of most human cancer types has been determined, a global characterisation of the immune tumour microenvironment in hepatocellular carcinoma (HCC) is lacking. Equally, differences in the immune contexture of HCC between different patient subgroups and its effect on survival remain to be established. Here we report an in silico analysis of the immune contexture of human HCC. Using large deep sequencing HCC tumour, adjacent non-tumour and healthy liver high-dimensional data sets, we were able to reveal previously unrecognized differences in the immune contexture of HCC. Strikingly, we found that different etiologies and HCC stages were not associated with major changes in the immune contexture. In contrast, the presence of T cells and cytotoxic cells as well as the absence of macrophages and Th2 cells positively correlated with patient survival. Based on these novel findings, we developed a prognostic score that accurately distinguishes between patients with good and poor survival. Our study provides the first global characterisation of the immune contexture of HCC and will have direct implications for future HCC therapies. PMID- 29599492 TI - No perceptual prioritization of non-nociceptive vibrotactile and visual stimuli presented on a sensitized body part. AB - High frequency electrical conditioning stimulation (HFS) is an experimental method to induce increased mechanical pinprick sensitivity in the unconditioned surrounding skin (secondary hyperalgesia). Secondary hyperalgesia is thought to be the result of central sensitization, i.e. increased responsiveness of nociceptive neurons in the central nervous system. Vibrotactile and visual stimuli presented in the area of secondary hyperalgesia also elicit enhanced brain responses, a finding that cannot be explained by central sensitization as it is currently defined. HFS may recruit attentional processes, which in turn affect the processing of all stimuli. In this study we have investigated whether HFS induces perceptual biases towards stimuli presented onto the sensitized arm by using Temporal Order Judgment (TOJ) tasks. In TOJ tasks, stimuli are presented in rapid succession on either arm, and participants have to indicate their perceived order. In case of a perceptual bias, the stimuli presented on the attended side are systematically reported as occurring first. Participants performed a tactile and a visual TOJ task before and after HFS. Analyses of participants' performance did not reveal any prioritization of the visual and tactile stimuli presented onto the sensitized arm. Our results provide therefore no evidence for a perceptual bias towards tactile and visual stimuli presented onto the sensitized arm. PMID- 29599493 TI - RING tetramerization is required for nuclear body biogenesis and PML sumoylation. AB - ProMyelocyticLeukemia nuclear bodies (PML NBs) are stress-regulated domains directly implicated in acute promyelocytic leukemia eradication. Most TRIM family members bind ubiquitin E2s and many acquire ligase activity upon RING dimerization. In contrast, PML binds UBC9, the SUMO E2 enzyme. Here, using X-ray crystallography and SAXS characterization, we demonstrate that PML RING tetramerizes through highly conserved PML-specific sequences, which are required for NB assembly and PML sumoylation. Conserved residues implicated in RING dimerization of other TRIMs also contribute to PML tetramer stability. Wild-type PML rescues the ability of some RING mutants to form NBs as well as their sumoylation. Impaired RING tetramerization abolishes PML/RARA-driven leukemogenesis in vivo and arsenic-induced differentiation ex vivo. Our studies thus identify RING tetramerization as a key step in the NB macro-molecular scaffolding. They suggest that higher order RING interactions allow efficient UBC9 recruitment and thus change the biochemical nature of TRIM-facilitated post translational modifications. PMID- 29599494 TI - Response analysis of host Spodoptera exigua larvae to infection by Heliothis virescens ascovirus 3h (HvAV-3h) via transcriptome. AB - Heliothis virescens ascovirus 3 h (HvAV-3h), a dsDNA insect virus, belonging to the family Ascoviridae, can infect caterpillars of several Noctuidae species by ovipositing parasitoid wasps. In order to provide a comprehensive overview of the interactive responses of host larvae after infection by the ascovirus, a transcriptome analysis of Spodoptera exigua to HvAV-3h was conducted from 6 to 168 hours post infection (hpi). Approximately 101.64 Gb of RNA sequencing (RNA seq) data obtained from infected and uninfected S. exigua larvae were used to perform a de novo transcriptome assembly, which generated approximately 62,258 S. exigua unigenes. Using differential gene expression analysis, it was determined that the majority of host transcripts were down-regulated beginning at 6 hpi and continuing throughout the infection period, although there was an increase in up regulated unigene number during the 12 to 72 hpi stage. It is noteworthy that the most abundantly enriched pathways in KEGG annotation were Metabolism terms, indicating that the host larval metabolic mechanisms were highly influenced post HvAV-3h infection. In addition, the host cuticle protein encoding unigenes were highly down-regulated in most of the situations, suggesting that the host larval cuticle synthesis were inhibited by the viral infection. PMID- 29599495 TI - Multilocus genetic profile in dopaminergic pathway modulates the striatum and working memory. AB - Dopamine is critical in pathophysiology and therapy of schizophrenia. Many studies have reported altered dopaminergic activity in the dorsal but not ventral striatum in schizophrenia. Based on the largest genome-wide association study of schizophrenia to date, we calculated the polygenic risk score (PGRS) of each subject in a healthy general group, including all variations in the set of functionally related genes involved in dopamine neurotransmitter system. We aimed to test whether the genetic variations in the dopaminergic pathway that have been identified as associated with schizophrenia are related to the function of the striatum and to working memory. We found that a higher PGRS was significantly associated with impairment in working memory. Moreover, resting-state functional connectivity analysis revealed that as the polygenic risk score increased, the connections between left putamen and caudate and the default mode network grew stronger, while the connections with the fronto-parietal network grew weaker. Our findings may shed light on the biological mechanism underlying the "dopamine hypothesis" of schizophrenia and provide some implications regarding the polygenic effects on the dopaminergic activity in the risk for schizophrenia. PMID- 29599496 TI - High fat diet alters Drosophila melanogaster sexual behavior and traits: decreased attractiveness and changes in pheromone profiles. AB - Sexual traits convey information about individual quality to potential mates. Environmental and genetic factors affect sexual trait expression and perception via effects on animal condition and health. High fat diet (HFD) is one environmental factor that adversely affects Drosophila melanogaster health, and its effects on animal health are mediated through conserved metabolic signaling pathways. HFD decreases female attractiveness, resulting in reduced male mating behaviors toward HFD females. HFD also affects the ability of males to judge mate attractiveness and likely alters fly condition and sexual traits to impact mating behavior. Here we show that HFD affects both visual (body size) and non-visual (pheromone profiles) sexual traits, which likely contribute to decreased fly attractiveness. We also demonstrate that adult-specific HFD effects on male mate preference can be rescued by changing metabolic signaling. These results demonstrate that HFD alters Drosophila sexual cues to reflect concurrent effects on condition and that less severe behavioral defects can be reversed by genetic manipulations that rescue fly health. This work expands on current knowledge of the role that metabolic signaling pathways play in linking animal health, sexual traits, and mating behavior, and provides a robust assay in a genetically tractable system to continue examining these processes. PMID- 29599498 TI - Polarized electron beams elastically scattered by atoms as a tool for testing fundamental predictions of quantum mechanics. AB - Quantum information theory deals with quantum noise in order to protect physical quantum bits (qubits) from its effects. A single electron is an emblematic example of a qubit, and today it is possible to experimentally produce polarized ensembles of electrons. In this paper, the theory of the polarization of electron beams elastically scattered by atoms is briefly summarized. Then the POLARe program suite, a set of computer programs aimed at the calculation of the spin polarization parameters of electron beams elastically interacting with atomic targets, is described. Selected results of the program concerning Ar, Kr, and Xe atoms are presented together with the comparison with experimental data about the Sherman function for low kinetic energy of the incident electrons (1.5eV-350eV). It is demonstrated that the quantum-relativistic theory of the polarization of electron beams elastically scattered by atoms is in good agreement with experimental data down to energies smaller than a few eV. PMID- 29599497 TI - Evaluation of a dimeric-cRGD peptide for targeted PET-CT imaging of peripheral angiogenesis in diabetic mice. AB - The alpha V beta3 integrin plays an important role in many physiological functions and pathological disorders. alpha V beta3 is minimally expressed in normal quiescent endothelial cells, but significantly upregulated during neovascularization. In this study, we evaluated a 64Cu-labeled dimeric cRGD tracer targeted at alpha V beta3 integrin and report its applicability to assess peripheral angiogenesis in diabetes mellitus (DM). We established a murine model of type-1 DM characterized by elevated glucose, glycated serum protein (GSP), and glycated hemoglobin A1c (HbA1c). We demonstrated that our imaging probe is specific to alpha V beta3 integrin under both normo- and hyperglycemic conditions. We found that the analysis of in vivo PET-CT images correlated well with gamma well counting (GWC). Both GWC and PET-CT imaging demonstrated increased uptake of 64Cu-NOTA-PEG4-cRGD2 in the ischemic hindlimb in contrast to non-ischemic control. GWC of the distal ischemic tissue from DM mice showed significantly lower probe accumulation than in non-DM mice. The immunofluorescence staining of the ischemic tissues showed a 3-fold reduction in CD31 and 4-fold reduction in the alpha V beta3 expression in DM vs. non-DM animals. In conclusion, we successfully demonstrated that diabetes-associated reductions in peripheral angiogenesis can be non-invasively detected with PET-CT imaging using targeted dimeric-cRGD probe. PMID- 29599499 TI - Neurons in the Pigeon Nidopallium Caudolaterale Display Value-Related Activity. AB - We recorded from neurons in the nidopallium caudolaterale, the avian equivalent of the mammalian prefrontal cortex, in four birds. The birds were required to peck a stimulus that indicated the amount of reward they would receive (small or large) after a certain delay (short or long). We found that the activity of neurons in the nidopallium caudolaterale was modulated by the value of the reward that would be received based on the reward amount and the delay to reward. We found that value coding was most prominent during the presentation of the sample period, and less so during the delay period and during the presentation of the reward itself. Our findings support the view that activity in nidopallium caudolaterale reflects the encoding of the value of reward based on a combination of reward amount and delay to a reward. PMID- 29599500 TI - Association of induced abortion with preterm birth risk in first-time mothers. AB - Women who have previously had an induced abortion (IA) before their first birth have been associated with preterm birth (PTB). However, previous studies on the PTB are inconsistent. Therefore, the aim of this study was to clarify the association between IA and PTB and low birth weight (LBW) for first-time mothers. A total of 3,684 Southern Chinese women who gave birth for the first time to a live singleton infants were recruited between January 2015 and December 2015 in the province of Guangdong, China. Univariable and multivariable analyses were conducted to determine whether IA was associated with PTB and LBW. Previous IA was not associated with increased risks of PTB or LBW, adjusted odds ratios were 0.80 (95% CI = 0.53 to 1.20) and 0.86 (95% CI = 0.57 to 1.31), respectively. Additionally, no significant associations were observed for infants born at before 37, before 32, and before 28 gestational weeks. And no significant associations were also observed for LBW measuring lower than 2500 grams and also measuring lower than 1500 grams. Our study suggested that a previous IA, as compared with women who reported no previous IA, does not increase the risk of PTB or LBW in subsequent pregnancy for the first-time mothers among Southern Chinese women. PMID- 29599501 TI - Piercing the dark matter: bioinformatics of long-range sequencing and mapping. AB - Several new genomics technologies have become available that offer long-read sequencing or long-range mapping with higher throughput and higher resolution analysis than ever before. These long-range technologies are rapidly advancing the field with improved reference genomes, more comprehensive variant identification and more complete views of transcriptomes and epigenomes. However, they also require new bioinformatics approaches to take full advantage of their unique characteristics while overcoming their complex errors and modalities. Here, we discuss several of the most important applications of the new technologies, focusing on both the currently available bioinformatics tools and opportunities for future research. PMID- 29599502 TI - Immunogenicity and Protection Against Influenza H7N3 in Mice by Modified Vaccinia Virus Ankara Vectors Expressing Influenza Virus Hemagglutinin or Neuraminidase. AB - Influenza subtypes such as H7 have pandemic potential since they are able to infect humans with severe consequences, as evidenced by the ongoing H7N9 infections in China that began in 2013. The diversity of H7 viruses calls for a broadly cross-protective vaccine for protection. We describe the construction of recombinant modified vaccinia virus Ankara (MVA) vectors expressing the hemagglutinin (HA) or neuraminidase (NA) from three H7 viruses representing both Eurasian and North American H7 lineages - A/mallard/Netherlands/12/2000 (H7N3), A/Canada/rv444/2004 (H7N3), and A/Shanghai/02/2013 (H7N9). These vectors were evaluated for immunogenicity and protective efficacy against H7N3 virus in a murine model of intranasal challenge. High levels of H7-, N3-, and N9-specific antibodies, including neutralizing antibodies, were induced by the MVA-HA and MVA NA vectors. Mice vaccinated with MVA vectors expressing any of the H7 antigens were protected, suggesting cross-protection among H7 viruses. In addition, MVA vectors expressing N3 but not N9 elicited protection against H7N3 virus challenge. Similar outcomes were obtained when immune sera from MVA vector immunized mice were passively transferred to naive mice prior to challenge with the H7N3 virus. The results support the further development of an MVA vector platform as a candidate vaccine for influenza strains with pandemic potential. PMID- 29599504 TI - Left main coronary artery disease: pathophysiology, diagnosis, and treatment. AB - The advent of coronary angiography in the 1960s allowed for the risk stratification of patients with stable angina. Patients with unprotected left main coronary artery disease have an increased risk of death related to the large amount of myocardium supplied by this vessel. Although coronary angiography remains the preferred imaging modality for the evaluation of left main coronary artery stenosis, this technique has important limitations. Angiograms of the left main coronary artery segment can be difficult to interpret, and almost one-third of patients can be misclassified when fractional flow reserve is used as the reference. In patients with clinically significant unprotected left main coronary artery disease, surgical revascularization was shown to improve survival compared with medical therapy and has been regarded as the treatment of choice for unprotected left main coronary artery disease. Two large-scale clinical trials published in 2016 support the usefulness of catheter-based revascularization in selected patients with unprotected left main coronary artery disease. In this Review, we describe the pathophysiology of unprotected left main coronary artery disease, discuss diagnostic approaches in light of new noninvasive and invasive imaging techniques, and detail risk stratification models to aid the Heart Team in the decision-making process for determining the best revascularization strategy for these patients. PMID- 29599503 TI - Zeb1-Hdac2-eNOS circuitry identifies early cardiovascular precursors in naive mouse embryonic stem cells. AB - Nitric oxide (NO) synthesis is a late event during differentiation of mouse embryonic stem cells (mESC) and occurs after release from serum and leukemia inhibitory factor (LIF). Here we show that after release from pluripotency, a subpopulation of mESC, kept in the naive state by 2i/LIF, expresses endothelial nitric oxide synthase (eNOS) and endogenously synthesizes NO. This eNOS/NO positive subpopulation (ESNO+) expresses mesendodermal markers and is more efficient in the generation of cardiovascular precursors than eNOS/NO-negative cells. Mechanistically, production of endogenous NO triggers rapid Hdac2 S nitrosylation, which reduces association of Hdac2 with the transcriptional repression factor Zeb1, allowing mesendodermal gene expression. In conclusion, our results suggest that the interaction between Zeb1, Hdac2, and eNOS is required for early mesendodermal differentiation of naive mESC. PMID- 29599505 TI - Ocean convection linked to the recent ice edge retreat along east Greenland. AB - Warm subtropical-origin Atlantic water flows northward across the Greenland Scotland Ridge into the Nordic Seas, where it relinquishes heat to the atmosphere and gradually transforms into dense Atlantic-origin water. Returning southward along east Greenland, this water mass is situated beneath a layer of cold, fresh surface water and sea ice. Here we show, using measurements from autonomous ocean gliders, that the Atlantic-origin water was re-ventilated while transiting the western Iceland Sea during winter. This re-ventilation is a recent phenomenon made possible by the retreat of the ice edge toward Greenland. The fresh surface layer that characterises this region in summer is diverted onto the Greenland shelf by enhanced onshore Ekman transport induced by stronger northerly winds in fall and winter. Severe heat loss from the ocean offshore of the ice edge subsequently triggers convection, which further transforms the Atlantic-origin water. This re-ventilation is a counterintuitive occurrence in a warming climate, and highlights the difficulties inherent in predicting the behaviour of the complex coupled climate system. PMID- 29599506 TI - 3.4 million real-world learning management system logins reveal the majority of students experience social jet lag correlated with decreased performance. AB - Misalignments between endogenous circadian rhythms and the built environment (i.e., social jet lag, SJL) result in learning and attention deficits. Currently, there is no way to assess the impact of SJL on learning outcomes of large populations as a response to schedule choices, let alone to assess which individuals are most negatively impacted by these choices. We analyzed two years of learning management system login events for 14,894 Northeastern Illinois University (NEIU) students to investigate the capacity of such systems as tools for mapping the impact of SJL over large populations while maintaining the ability to generate insights about individuals. Personal daily activity profiles were validated against known biological timing effects, and revealed a majority of students experience more than 30 minutes of SJL on average, with greater amplitude correlating strongly with a significant decrease in academic performance, especially in people with later apparent chronotypes. Our findings demonstrate that online records can be used to map individual- and population level SJL, allow deep mining for patterns across demographics, and could guide schedule choices in an effort to minimize SJL's negative impact on learning outcomes. PMID- 29599507 TI - Head tracking extends local active control of broadband sound to higher frequencies. AB - Local active sound control systems provide useful reductions in noise within a zone of quiet which only extends to about one tenth of an acoustic wavelength. If active control is required above a few hundred hertz, this generally limits the movement of a listener to unrealistically small changes in head position. We describe a local active sound control system using a fixed array of monitoring microphones, in which the pressures at the ear positions are estimated from these microphone signals using head position information from an optical head tracker. These signals are then actively controlled to give robust attenuation at the ear positions, even as the listener moves their head. Feedforward control provides selective attenuation of noise and broadband attenuation of around 20 dB is measured up to excitation frequencies of 1 kHz under favourable conditions, with head tracking achieved in a few seconds. The active control performance is thus comparable with that achieved with active headphones, but without the listener having anything attached to their head. PMID- 29599508 TI - The association between red blood cell transfusion and outcomes in patients with upper gastrointestinal bleeding. AB - BACKGROUND: The benefits of transfusion for acute upper gastrointestinal bleeding (UGIB) have not been well established; however, previous studies suggest that transfusion is associated with adverse outcomes. We performed an observational study using a 10-year database to analyze the association between red blood cell (RBC) transfusion and outcomes in patients with UGIB in the emergency department (ED). METHOD AND FINDINGS: All adult patients with UGIB were identified through diagnostic codes. Hospital mortality was the primary outcome; further bleeding was the secondary outcome. Logistic regression, propensity analyses, and conditional logistic regression were performed to determine factors associated with outcomes. Of 59,188 enrolled patients, 31.6% (n = 18,705) received RBC transfusions within 24 h following presentation to the ED. Hospital mortality was noted in 3.9 and 10.6% of the patients in the non-RBC transfusion and RBC transfusion groups, respectively (P < 0.001). RBC transfusion was associated with increased mortality risk (unadjusted odds ratio (OR) 2.95, 95% confidence interval (CI) 2.75-3.16; P < 0.001) among all patients and in the propensity matched cohort (unadjusted OR 1.55, 95% CI 1.39-1.72; P < 0.001). Further bleeding was noted in 5.6 and 33.8% of the patients in the non-RBC transfusion and RBC transfusion groups, respectively (P < 0.001). RBC transfusion was associated with increased risk of further bleeding (unadjusted OR 8.60, 95% CI 8.16-9.06; P < 0.001) among all patients and in the propensity-matched cohort (unadjusted OR 2.58, 95% CI 2.37-2.79; P < 0.001). CONCLUSION: RBC transfusion was significantly associated with increased rates of hospital mortality and further bleeding in patients with UGIB. Although our findings have strengths, these results are not generalizable to all patients presenting with UGIB, especially patients presenting with exsanguinating bleeding. Additional prospective trials to guide optimal transfusion strategies in UGIB patients are needed. PMID- 29599509 TI - Hidden genomic MHC disparity between HLA-matched sibling pairs in hematopoietic stem cell transplantation. AB - Matching classical HLA alleles between donor and recipient is an important factor in avoiding adverse immunological effects in HSCT. Siblings with no differences in HLA alleles, either due to identical-by-state or identical-by-descent status, are considered to be optimal donors. We carried out a retrospective genomic sequence and SNP analysis of 336 fully HLA-A, -B, -DRB1 matched and 14 partially HLA-matched sibling HSCT pairs to determine the level of undetected mismatching within the MHC segment as well as to map their recombination sites. The genomic sequence of 34 genes locating in the MHC region revealed allelic mismatching at 1 to 8 additional genes in partially HLA-matched pairs. Also, fully matched pairs were found to have mismatching either at HLA-DPB1 or at non-HLA region within the MHC segment. Altogether, 3.9% of fully HLA-matched HSCT pairs had large genomic mismatching in the MHC segment. Recombination sites mapped to certain restricted locations. The number of mismatched nucleotides correlated with the risk of GvHD supporting the central role of full HLA matching in HSCT. High-density genome analysis revealed that fully HLA-matched siblings may not have identical MHC segments and even single allelic mismatching at any classical HLA gene often implies larger genomic differences along MHC. PMID- 29599510 TI - Nitrogen uptake kinetics and saltmarsh plant responses to global change. AB - Coastal wetlands are important carbon sinks globally, but their ability to store carbon hinges on their nitrogen (N) supply and N uptake dynamics of dominant plant species. In terrestrial ecosystems, uptake of nitrate (NO3-) and ammonium (NH4+) through roots can strongly influence N acquisition rates and their responses to environmental factors such as rising atmospheric CO2 and eutrophication. We examined the 15N uptake kinetics of three dominant plant species in North American coastal wetlands (Spartina patens, C4 grass; Phragmites australis, C3 grass; Schoenoplectus americanus, C3 sedge) under ambient and elevated CO2 conditions. We further related our results to the productivity response of these species in two long-term field experiments. S. patens had the greatest uptake rates for NO3- and NH4+ under ambient conditions, suggesting that N uptake kinetics may underlie its strong productivity response to N in the field. Elevated CO2 increased NH4+ and NO3- uptake rates for S. patens, but had negative effects on NO3- uptake rates in P. australis and no effects on S. americanus. We suggest that N uptake kinetics may explain differences in plant community composition in coastal wetlands and that CO2-induced shifts, in combination with N proliferation, could alter ecosystem-scale productivity patterns of saltmarshes globally. PMID- 29599511 TI - A Mathematical Model for the Sounds Produced by Knuckle Cracking. AB - The articular release of the metacarpophalangeal joint produces a typical cracking sound, resulting in what is commonly referred to as the cracking of knuckles. Despite over sixty years of research, the source of the knuckle cracking sound continues to be debated due to inconclusive experimental evidence as a result of limitations in the temporal resolution of non-invasive physiological imaging techniques. To support the available experimental data and shed light onto the source of the cracking sound, we have developed a mathematical model of the events leading to the generation of the sound. The model resolves the dynamics of a collapsing cavitation bubble in the synovial fluid inside a metacarpophalangeal joint during an articular release. The acoustic signature from the resulting bubble dynamics is shown to be consistent in both magnitude and dominant frequency with experimental measurements in the literature and with our own experiments, thus lending support for cavitation bubble collapse as the source of the cracking sound. Finally, the model also shows that only a partial collapse of the bubble is needed to replicate the experimentally observed acoustic spectra, thus allowing for bubbles to persist following the generation of sound as has been reported in recent experiments. PMID- 29599512 TI - Population genetic evidence for positive and purifying selection acting at the human IFN-gamma locus in Africa. AB - Despite its critical role in the defense against microbial infection and tumor development, little is known about the range of nucleotide and haplotype variation at IFN-gamma, or the evolutionary forces that have shaped patterns of diversity at this locus. To address this gap in knowledge, we examined sequence data from the IFN-gamma gene in 1461 individuals from 15 worldwide populations. Our analyses uncovered novel patterns of variation in distinct African populations, including an excess of high frequency-derived alleles, unusually long haplotype structure surrounding the IFN-gamma gene, and a "star-like" genealogy of African-specific haplotypes carrying variants previously associated with infectious disease. We also inferred a deep time to coalescence of variation at IFN-gamma (~ 0.8 million years ago) and ancient ages for common polymorphisms predating the evolution of modern humans. Taken together, these results are congruent with a model of positive selection on standing variation in African populations. Furthermore, we inferred that common variants in intron 3 of IFN gamma are the likely targets of selection. In addition, we observed a paucity of non-synonymous substitutions relative to synonymous changes in the exons of IFN gamma in African and non-African populations, suggestive of strong purifying selection. Therefore, we contend that positive and purifying selection have influenced levels of diversity in different regions of IFN-gamma, implying that these distinct genic regions are, or have been, functionally important. Overall, this study provides additional insights into the evolutionary events that have contributed to the frequency and distribution of alleles having a role in human health and disease. PMID- 29599513 TI - Akkermansia muciniphila is permissive to arthritis in the K/BxN mouse model of arthritis. AB - Studies have identified abnormalities in the microbiota of patients with arthritis. To evaluate the pathogenicity of human microbiota, we performed fecal microbial transplantation from children with spondyloarthritis and controls to germ-free KRN/B6xNOD mice. Ankle swelling was equivalent in those that received patient vs. control microbiota. Principal coordinates analysis revealed incomplete uptake of the human microbiota with over-representation of two genera (Bacteroides and Akkermansia) among the transplanted mice. The microbiota predicted the extent of ankle swelling (R2 = 0.185, p = 0.018). The abundances of Bacteroides (r = -0.510, p = 0.010) inversely and Akkermansia (r = 0.367, p = 0.078) directly correlated with ankle swelling. Addition of Akkermansia muciniphila to Altered Schaedler's Flora (ASF) resulted in small but statistically significant increased ankle swelling as compared to mice that received ASF alone (4.0 mm, 3.9-4.1 vs. 3.9 mm, IQR 3.6-4.0, p = 0.041), as did addition of A. muciniphila cultures to transplanted human microbiota as compared to mice that received transplanted human microbiota alone (4.5 mm, IQR 4.3-5.5 vs. 4.1 mm, IQR 3.9-4.3, p = 0.019). This study supports previous findings of an association between A. muciniphila and arthritis. PMID- 29599514 TI - Human IL12RB1 expression is allele-biased and produces a novel IL12 response regulator. AB - Human IL12RB1 is an autosomal gene that is essential for mycobacterial disease resistance and T cell differentiation. Using primary human tissue and PBMCs, we demonstrate that lung and T cell IL12RB1 expression is allele-biased, and the extent to which cells express one IL12RB1 allele is unaffected by activation. Furthermore following its expression the IL12RB1 pre-mRNA is processed into either IL12RB1 Isoform 1 (IL12Rbeta1, a positive regulator of IL12 responsiveness) or IL12RB1 Isoform 2 (a protein of heretofore unknown function). T cells choice to process pre-mRNA into Isoform 1 or Isoform 2 is controlled by intragenic competition of IL12RB1 exon 9-10 splicing with IL12RB1 exon 9b splicing, as well as an IL12RB1 exon 9b-associated polyadenylation site. Heterogeneous nuclear ribonucleoprotein H (hnRNP H) binds near the regulated polyadenylation site, but is not required for exon 9b polyadenylation. Finally, microRNA-mediated knockdown experiments demonstrated that IL12RB1 Isoform 2 promotes T cell IL12 responses. Collectively, our data support a model wherein tissue expression of human IL12RB1 is allele-biased and produces an hnRNP H-bound pre-mRNA, the processing of which generates a novel IL12 response regulator. PMID- 29599515 TI - Src signaling in a low-complexity unicellular kinome. AB - Creolimax fragrantissima is a member of the ichthyosporean clade, the earliest branching holozoan lineage. The kinome of Creolimax is markedly reduced as compared to those of metazoans. In particular, Creolimax possesses a single non receptor tyrosine kinase: CfrSrc, the homolog of c-Src kinase. CfrSrc is an active tyrosine kinase, and it is expressed throughout the lifecycle of Creolimax. In animal cells, the regulatory mechanism for Src involves tyrosine phosphorylation at a C-terminal site by Csk kinase. The lack of Csk in Creolimax suggests that a different mode of negative regulation must exist for CfrSrc. We demonstrate that CfrPTP-3, one of the 7 tyrosine-specific phosphatases (PTPs) in Creolimax, suppresses CfrSrc activity in vitro and in vivo. Transcript levels of CfrPTP-3 and two other PTPs are significantly higher than that of CfrSrc in the motile amoeboid and sessile multinucleate stages of the Creolimax life cycle. Thus, in the context of a highly reduced kinome, a pre-existing PTP may have been co-opted for the role of Src regulation. Creolimax represents a unique model system to study the adaptation of tyrosine kinase signaling and regulatory mechanisms. PMID- 29599516 TI - Enterobacter bugandensis: a novel enterobacterial species associated with severe clinical infection. AB - Nosocomial pathogens can cause life-threatening infections in neonates and immunocompromised patients. E. bugandensis (EB-247) is a recently described species of Enterobacter, associated with neonatal sepsis. Here we demonstrate that the extended spectrum beta-lactam (ESBL) producing isolate EB-247 is highly virulent in both Galleria mellonella and mouse models of infection. Infection studies in a streptomycin-treated mouse model showed that EB-247 is as efficient as Salmonella Typhimurium in inducing systemic infection and release of proinflammatory cytokines. Sequencing and analysis of the complete genome and plasmid revealed that virulence properties are associated with the chromosome, while antibiotic-resistance genes are exclusively present on a 299 kb IncHI plasmid. EB-247 grew in high concentrations of human serum indicating septicemic potential. Using whole genome-based transcriptome analysis we found 7% of the genome was mobilized for growth in serum. Upregulated genes include those involved in the iron uptake and storage as well as metabolism. The lasso peptide microcin J25 (MccJ25), an inhibitor of iron-uptake and RNA polymerase activity, inhibited EB-247 growth. Our studies indicate that Enterobacter bugandensis is a highly pathogenic species of the genus Enterobacter. Further studies on the colonization and virulence potential of E. bugandensis and its association with septicemic infection is now warranted. PMID- 29599517 TI - Increasing prosthetic foot energy return affects whole-body mechanics during walking on level ground and slopes. AB - Prosthetic feet are designed to store energy during early stance and then release a portion of that energy during late stance. The usefulness of providing more energy return depends on whether or not that energy transfers up the lower limb to aid in whole body propulsion. This research examined how increasing prosthetic foot energy return affected walking mechanics across various slopes. Five people with a uni-lateral transtibial amputation walked on an instrumented treadmill at 1.1 m/s for three conditions (level ground, +7.5 degrees , -7.5 degrees ) while wearing a prosthetic foot with a novel linkage system and a traditional energy storage and return foot. The novel foot demonstrated greater range of motion (p = 0.0012), and returned more energy (p = 0.023) compared to the traditional foot. The increased energy correlated with an increase in center of mass (CoM) energy change during propulsion from the prosthetic limb (p = 0.012), and the increased prosthetic limb propulsion correlated to a decrease in CoM energy change (i.e., collision) on the sound limb (p < 0.001). These data indicate that this novel foot was able to return more energy than a traditional prosthetic foot and that this additional energy was used to increase whole body propulsion. PMID- 29599518 TI - Psychological outcomes and surgical decisions after genetic testing in women newly diagnosed with breast cancer with and without a family history. AB - In patients with early breast cancer, personal and tumour characteristics other than family history are increasingly used to prompt genetic testing to guide women's cancer management (treatment-focused genetic testing, 'TFGT'). Women without a known strong family history of breast and/or ovarian may be more vulnerable to psychological sequelae arising from TFGT. We compared the impact of TFGT in women with (FH+) and without (FH-) a strong family history on psychological adjustment and surgical decisions. Women aged <50 years with high risk features were offered TFGT before definitive breast cancer surgery and completed self-report questionnaires at four time points over 12 months. All 128 women opted for TFGT. TFGT identified 18 carriers of a disease-causing variant (50.0% FH+) and 110 non-carriers (59.1% FH+). There were no differences based on family history in bilateral mastectomy (BM) uptake, p = .190, or uptake of risk reducing bilateral salpingo-oophorectomy (RRBSO), p = .093. FH- women had lower decreases in anxiety a year after diagnosis, p = .011, and regret regarding their decision whether to undergo BM, p = .022, or RRBSO, p = .016 than FH + women. FH- carriers reported significantly higher regret regarding their TFGT choice (p = .024) and test-related distress (p = .012) than FH + carriers, but this regret/distress could not be attributed to a concern regarding a possible worse prognosis. These findings indicate that FH- women may require additional counselling to facilitate informed decisions. Carriers without a family history may require additional follow-up counselling to facilitate psychological adjustment to their positive variant results, extra support in making surgical decisions, and counselling about how best to communicate results to family members. PMID- 29599519 TI - Cultivation and genomics of the first freshwater SAR11 (LD12) isolate. AB - Evolutionary transitions between fresh and salt water happen infrequently among bacterioplankton. Within the ubiquitous and highly abundant heterotrophic Alphaproteobacteria order Pelagibacterales (SAR11), most members live in marine habitats, but the LD12 subclade has evolved as a unique freshwater lineage. LD12 cells occur as some of the most dominant freshwater bacterioplankton, yet this group has remained elusive to cultivation, hampering a more thorough understanding of its biology. Here, we report the first successful isolation of an LD12 representative, strain LSUCC0530, using high-throughput dilution-to extinction cultivation methods, and its complete genome sequence. Growth experiments corroborate ecological data suggesting active populations of LD12 in brackish water up to salinities of ~5. LSUCC0530 has the smallest closed genome thus far reported for a SAR11 strain (1.16 Mbp). The genome affirms many previous metabolic predictions from cultivation-independent analyses, like a complete Embden-Meyerhof-Parnas glycolysis pathway, but also provides novel insights, such as the first isocitrate dehydrogenase in LD12, a likely homologous recombination of malate synthase from outside of the SAR11 clade, and analogous substitutions of ion transporters with others that occur throughout the rest of the SAR11 clade. Growth data support metagenomic recruitment results suggesting temperature based ecotype diversification within LD12. Key gene losses for osmolyte uptake provide a succinct hypothesis for the evolutionary transition of LD12 from salt to freshwater. For strain LSUCC0530, we propose the provisional nomenclature Candidatus fonsibacter ubiquis. PMID- 29599520 TI - Short-term dynamics and interactions of marine protist communities during the spring-summer transition. AB - We examined the short-term variability, by daily to weekly sampling, of protist assemblages from March to July in surface water of the San Pedro Ocean Time series station (eastern North Pacific), by V4 Illumina sequencing of the 18S rRNA gene. The sampling period encompassed a spring bloom followed by progression to summer conditions. Several protistan taxa displayed sharp increases and declines, with whole community Bray-Curtis dissimilarities of adjacent days being 66% in March and 40% in May. High initial abundance of parasitic Cercozoa Cryothecomonas longipes and Protaspis grandis coincided with a precipitous decline of blooming Pseudo-nitzschia diatoms, possibly suggesting their massive infection by these parasites; these cercozoans were hardly detectable afterwards. Canonical correspondence analysis indicated a limited predictability of community variability from environmental factors. This indicates that other factors are relevant in explaining changes in protist community composition at short temporal scales, such as interspecific relationships, stochastic processes, mixing with adjacent water, or advection of patches with different protist communities. Association network analysis revealed that interactions between the many parasitic OTUs and other taxa were overwhelmingly positive and suggest that although sometimes parasites may cause a crash of host populations, they may often follow their hosts and do not regularly cause enough mortality to potentially create negative correlations at the daily to weekly time scales we studied. PMID- 29599521 TI - Demographic fluctuation of community-acquired antibiotic-resistant Staphylococcus aureus lineages: potential role of flimsy antibiotic exposure. AB - Community-acquired (CA)- as opposed to hospital acquired- methicillin-resistant Staphylococcus aureus (MRSA) lineages arose worldwide during the 1990s. To determine which factors, including selective antibiotic pressure, govern the expansion of two major lineages of CA-MRSA, namely "USA300" in Northern America and "European ST80" in North Africa, Europe and Middle-East, we explored virulence factor expression, and fitness levels with or without antibiotics. The sampled strains were collected in a temporal window representing various steps of the epidemics, reflecting predicted changes in effective population size as inferred from whole-genome analysis. In addition to slight variations in virulence factor expression and biofilm production that might influence the ecological niches of theses lineages, competitive fitness experiments revealed that the biological cost of resistance to methicillin, fusidic acid and fluoroquinolones is totally reversed in the presence of trace amount of antibiotics. Our results suggest that low-level antibiotics exposure in human and animal environments contributed to the expansion of both European ST80 and USA300 lineages in community settings. This surge was likely driven by antibiotic (ab)use promoting the accumulation of antibiotics as environmental pollutants. The current results provide a novel link between effective population size increase of a pathogen and a selective advantage conferred by antibiotic resistance.

AB - Exposure to dietary sources of methylmercury (MeHg) is the focus of public health concerns with environmental mercury (Hg) contamination. MeHg is formed in anoxic environments by anaerobic microorganisms. This process has been studied mostly with single-species culture incubations, although the relevance of such studies to Hg(II)-methylation in situ is limited because microbial activities in the environment are critically modulated by interactions among microbial functional groups. Here we describe experiments in which Hg(II)-methylation was examined within the context of various microbial syntrophies. We show enhanced Hg(II) methylation under conditions that established syntrophy by interspecies hydrogen and acetate transfer. Relative to activity of monocultures, interactions of Hg(II) methylating sulfate-reducing bacteria with a methanogen stimulated potential Hg(II)-methylation rates 2-fold to 9-fold, and with Syntrophobacter sp. 1.7-fold to 1.8-fold; those of a Hg(II) methylating Syntrophobacter sp. with a methanogen increased Hg(II)-methylation 2-fold. Under sulfate-depleted conditions, higher Hg(II)-methylation rates in the syntrophic incubations corresponded to higher free energy yields (DeltaG degrees ') than in the monocultures. Based on energetic considerations, we therefore propose that syntrophic microbial interactions are likely a major source of MeHg in sulfate- and iron-limited anoxic environments while in sulfate-replete environments, MeHg formation via sulfate reduction dominates. PMID- 29599523 TI - Grazer-induced transcriptomic and metabolomic response of the chain-forming diatom Skeletonema marinoi. AB - Diatoms and copepods are main actors in marine food webs. The prey-predator interactions between them affect bloom dynamics, shape marine ecosystems and impact the energy transfer to higher trophic levels. Recently it has been demonstrated that the presence of grazers may affect the diatom prey beyond the direct effect of grazing. Here, we investigated the response of the chain-forming centric diatom Skeletonema marinoi to grazer cues, including changes in morphology, gene expression and metabolic profile. S. marinoi cells were incubated with Calanus finmarchicus or with Centropages typicus and in both cases responded by reducing the chain length, whereas changes in gene expression indicated an activation of stress response, changes in the lipid and nitrogen metabolism, in cell cycle regulation and in frustule formation. Transcripts linked to G protein-coupled receptors and to nitric oxide synthesis were differentially expressed suggesting involvement of these signalling transduction pathways in the response. Downregulation of a lipoxygenase in the transcriptomic data and of its products in the metabolomic data also indicate an involvement of oxylipins. Our data contribute to a better understanding of the gene function in diatoms, providing information on the nature of genes implicated in the interaction with grazers, a crucial process in marine ecosystems. PMID- 29599524 TI - Thermophilic endospores associated with migrated thermogenic hydrocarbons in deep Gulf of Mexico marine sediments. AB - Dormant endospores of thermophilic bacteria (thermospores) can be detected in cold marine sediments following high-temperature incubation. Thermospores in the cold seabed may be explained by a dispersal history originating in deep biosphere oil reservoir habitats where upward migration of petroleum fluids at hydrocarbon seeps transports viable cells into the overlying ocean. We assessed this deep-to shallow dispersal hypothesis through geochemical and microbiological analyses of 111 marine sediments from the deep water Eastern Gulf of Mexico. GC-MS and fluorescence confirmed the unambiguous presence of thermogenic hydrocarbons in 71 of these locations, indicating seepage from deeply sourced petroleum in the subsurface. Heating each sediment to 50 degrees C followed by 16S rRNA gene sequencing revealed several thermospores with a cosmopolitan distribution throughout the study area, as well as thermospores that were more geographically restricted. Among the thermospores having a more limited distribution, 12 OTUs from eight different lineages were repeatedly detected in sediments containing thermogenic hydrocarbons. A subset of these were significantly correlated with hydrocarbons (p < 0.05) and most closely related to Clostridiales previously detected in oil reservoirs from around the world. This provides evidence of bacteria in the ocean being dispersed out of oil reservoirs, and suggests that specific thermospores may be used as model organisms for studying warm-to-cold transmigration in the deep sea. PMID- 29599525 TI - A role for the gibberellin pathway in biochar-mediated growth promotion. AB - Biochar is a carbon negative soil amendment that can promote crop growth. However, the effects of biochar on different plant species and cultivars within a species are not well understood, nor is the underlying basis of biochar-mediated plant growth promotion. This knowledge is critical for optimal use of biochar and for breeding biochar-responsive plants. Here, we investigated the genotype specific effects of biochar on two cultivars of Solanum lycopersicum (tomato), and two wild relatives of tomato, Solanum pimpinellifolium, and Solanum pennelli, in two types of biochar. Biochar promoted shoot growth in all genotypes independent of biochar type but had genotype-dependent effects on other plant traits. Germination tests, exogenous GA4 application and mutant analysis indicated a role for GA in biochar-mediated plant growth promotion. Together, our results suggest that biochar promotes growth partially through stimulation of the GA pathway. PMID- 29599526 TI - (More) women in science. PMID- 29599527 TI - The mitochondrial outer-membrane location of the EXD2 exonuclease contradicts its direct role in nuclear DNA repair. AB - EXD2 is a recently identified exonuclease that has been implicated in nuclear double-strand break repair. Given our long standing interest in mitochondrial DNA maintenance and indications that EXD2 could also be a mitochondrial protein we sought to determine its cellular localization and possible mitochondrial associated functions. Our results show that EXD2 indeed shows mitochondrial localization, but, surprisingly, is found predominantly associated with the mitochondrial outer-membrane. Gradient purified nuclei show only the faintest hint of EXD2 presence while overexpression of the predicted full-length protein shows exclusive mitochondrial localization. Importantly, induction of double strand DNA breaks via X-irradiation or Zeocin treatment does not support the notion that EXD2 re-locates to the nucleus following double-strand breaks and thus is unlikely to have a direct role in nuclear DNA repair. Knockdown or overexpression of EXD2 affects the cellular distribution of mitochondria. These results suggest that the reported defects in nuclear DNA repair following EXD2 depletion are likely an indirect consequence of altered mitochondrial dynamics and/or function.

PMID- 29599529 TI - Interbrain cortical synchronization encodes multiple aspects of social interactions in monkey pairs. AB - While it is well known that the primate brain evolved to cope with complex social contingencies, the neurophysiological manifestation of social interactions in primates is not well understood. Here, concurrent wireless neuronal ensemble recordings from pairs of monkeys were conducted to measure interbrain cortical synchronization (ICS) during a whole-body navigation task that involved continuous social interaction of two monkeys. One monkey, the passenger, was carried in a robotic wheelchair to a food dispenser, while a second monkey, the observer, remained stationary, watching the passenger. The two monkeys alternated the passenger and the observer roles. Concurrent neuronal ensemble recordings from the monkeys' motor cortex and the premotor dorsal area revealed episodic occurrence of ICS with probability that depended on the wheelchair kinematics, the passenger-observer distance, and the passenger-food distance - the social interaction factors previously described in behavioral studies. These results suggest that ICS represents specific aspects of primate social interactions. PMID- 29599530 TI - Excessive activated T-cell proliferation after anti-CD19 CAR T-cell therapy. AB - Excessive activated T-cell proliferation was observed in vivo in one patient after an anti-CD19-chimeric antigen receptor (CAR) T-cell infusion. The patient, who had chemotherapy refractory and CD19+ diffuse large B-cell lymphoma (DLBCL), received an anti-CD19 CAR T-cell infusion following conditioning chemotherapy (fludarabine/cyclophosphamide). The lymphocyte count in the peripheral blood (PB) increased to 77 * 109/L on day 13 post infusion, and the proportion of CD8+ actived T cells was 93.06% of the lymphocytes. Then, the patient suffered from fever and hypoxaemia. Significant increases in serum cytokine, lactate dehydrogenase, aspartate aminotransferase (AST), alanine transaminase (ALT), and glutamic-oxalacetic transaminase (gamma-GT) levels were observed. A high throughput sequencing analysis for T-cell receptors (TCRs) and whole-genome sequencing were used to explore the mechanisms underlying this excessive T-cell proliferation. TCR diversity was demonstrated, but no special gene mutation was found. The patient was found to be infected with the John Cunningham polyomavirus (JCV). It cannot be ruled out the bystander activation pathway induced by JCV infections related the excessive activated T-cell proliferation. Although the clinical and laboratory data do not fully explain the reason for excessive T-cell proliferation after the anti-CD19 CAR T-cell infusion, the risk of this type of toxicity should be emphasized. This study was registered at www.clinicaltrials.gov as NCT01864889. PMID- 29599531 TI - Collaborative hierarchy maintains cooperation in asymmetric games. AB - The interplay of social structure and cooperative behavior is under much scrutiny lately as behavior in social contexts becomes increasingly relevant for everyday life. Earlier experimental work showed that the existence of a social hierarchy, earned through competition, was detrimental for the evolution of cooperative behaviors. Here, we study the case in which individuals are ranked in a hierarchical structure based on their performance in a collective effort by having them play a Public Goods Game. In the first treatment, participants are ranked according to group earnings while, in the second treatment, their rankings are based on individual earnings. Subsequently, participants play asymmetric Prisoner's Dilemma games where higher-ranked players gain more than lower ones. Our experiments show that there are no detrimental effects of the hierarchy formed based on group performance, yet when ranking is assigned individually we observe a decrease in cooperation. Our results show that different levels of cooperation arise from the fact that subjects are interpreting rankings as a reputation which carries information about which subjects were cooperators in the previous phase. Our results demonstrate that noting the manner in which a hierarchy is established is essential for understanding its effects on cooperation. PMID- 29599532 TI - [Job satisfaction vs. occupational stress - Quantitative analysis of 3 organizational units of a public sector institution]. AB - BACKGROUND: The influence of subjective perception of occupational stress and its individual factors on the overall level of job satisfaction was analyzed. The respondents were also asked to answer the question of the potential differences in terms of variables in managers and non-managers, and in various demographic factors. MATERIAL AND METHODS: This article presents the results of a study conducted among 5930 people employed in 3 units of the examined public sector institution. The research was conducted using computer-assisted web interview method. The parameters of the polynomial model of ordered categories were estimated. RESULTS: The results showed a statistically significant effect between the variables and the differences between the groups of subjects. Analyzes showed slight differences between men and women. Employees with a low level of stress and high job satisfaction were noted in the oldest group, aged over 55 years, and in managers. Low levels of stress and job satisfaction were observed in young employees with the shortest period of employment. Among those least satisfied with the work and experiencing high levels of stress there were respondents with 6-15 years of employment in non-managerial positions. While the highest levels of stress and high satisfaction were found in people aged 46-55 years, with more than 20 years of work experience. CONCLUSIONS: The results of the estimation of the polynomial model parameters of ordered categories indicate that the level of perceived stress is related to the level of job satisfaction. The lower the level of stress and stressors in the workplace, the greater the job satisfaction in the surveyed unit. Med Pr 2018;69(3):301-315. PMID- 29599533 TI - Conceptions of Good Science in Our Data-Rich World. AB - Scientists have been debating for centuries the nature of proper scientific methods. Currently, criticisms being thrown at data-intensive science are reinvigorating these debates. However, many of these criticisms represent long standing conflicts over the role of hypothesis testing in science and not just a dispute about the amount of data used. Here, we show that an iterative account of scientific methods developed by historians and philosophers of science can help make sense of data-intensive scientific practices and suggest more effective ways to evaluate this research. We use case studies of Darwin's research on evolution by natural selection and modern-day research on macrosystems ecology to illustrate this account of scientific methods and the innovative approaches to scientific evaluation that it encourages. We point out recent changes in the spheres of science funding, publishing, and education that reflect this richer account of scientific practice, and we propose additional reforms. PMID- 29599534 TI - Harmonizing Biodiversity Conservation and Productivity in the Context of Increasing Demands on Landscapes. AB - Biodiversity conservation and agricultural production are often seen as mutually exclusive objectives. Strategies for reconciling them are intensely debated. We argue that harmonization between biodiversity conservation and crop production can be improved by increasing our understanding of the underlying relationships between them. We provide a general conceptual framework that links biodiversity and agricultural production through the separate relationships between land use and biodiversity and between land use and production. Hypothesized relationships are derived by synthesizing existing empirical and theoretical ecological knowledge. The framework suggests nonlinear relationships caused by the multifaceted impacts of land use (composition, configuration, and intensity). We propose solutions for overcoming the apparently dichotomous aims of maximizing either biodiversity conservation or agricultural production and suggest new hypotheses that emerge from our proposed framework. PMID- 29599535 TI - Prospects for Increasing Sugarcane and Bioethanol Production on Existing Crop Area in Brazil. AB - This article assesses sugarcane yield gaps (YG) in Brazil to determine the degree to which production can be increased without land expansion. In our scenario assessments, we evaluated how much of the projected sugarcane demand to 2024 (for both sugar and bioethanol) can be satisfied through YG closure. The current national average yield is 62% of yield potential estimated for rainfed conditions (i.e., a YG of 38%). Continuing the historical rate of yield gain is not sufficient to meet the projected demand without an area expansion by 5% and 45% for low- and high-demand scenarios, respectively. Closing the exploitable YG to 80% of potential yield would meet future sugarcane demand, with an 18% reduction in sugarcane area for the low-demand scenario or a 13% expansion for the high demand scenario. A focus on accelerating yield gains to close current exploitable YG is a high priority for meeting future demand while minimizing pressure on additional land requirements. PMID- 29599536 TI - Critical Uncertainties and Gaps in the Environmental- and Social-Impact Assessment of the Proposed Interoceanic Canal through Nicaragua. AB - The proposed interoceanic canal will connect the Caribbean Sea with the Pacific Ocean, traversing Lake Nicaragua, the major freshwater reservoir in Central America. If completed, the canal would be the largest infrastructure-related excavation project on Earth. In November 2015, the Nicaraguan government approved an environmental and social impact assessment (ESIA) for the canal. A group of international experts participated in a workshop organized by the Academy of Sciences of Nicaragua to review this ESIA. The group concluded that the ESIA does not meet international standards; essential information is lacking regarding the potential impacts on the lake, freshwater and marine environments, and biodiversity. The ESIA presents an inadequate assessment of natural hazards and socioeconomic disruptions. The panel recommends that work on the canal project be suspended until an appropriate ESIA is completed. The project should be resumed only if it is demonstrated to be economically feasible, environmentally acceptable, and socially beneficial. PMID- 29599537 TI - The Multitrophic Effects of Climate Change and Glacier Retreat in Mountain Rivers. AB - Climate change is driving the thinning and retreat of many glaciers globally. Reductions of ice-melt inputs to mountain rivers are changing their physicochemical characteristics and, in turn, aquatic communities. Glacier-fed rivers can serve as model systems for investigations of climate-change effects on ecosystems because of their strong atmospheric-cryospheric links, high biodiversity of multiple taxonomic groups, and significant conservation interest concerning endemic species. From a synthesis of existing knowledge, we develop a new conceptual understanding of how reducing glacier cover affects organisms spanning multiple trophic groups. Although the response of macroinvertebrates to glacier retreat has been well described, we show that there remains a relative paucity of information for biofilm, microinvertebrate, and vertebrate taxa. Enhanced understanding of whole river food webs will improve the prediction of river-ecosystem responses to deglaciation while offering the potential to identify and protect a wider range of sensitive and threatened species. PMID- 29599538 TI - From Agricultural Benefits to Aviation Safety: Realizing the Potential of Continent-Wide Radar Networks. AB - Migratory animals provide a multitude of services and disservices-with benefits or costs in the order of billions of dollars annually. Monitoring, quantifying, and forecasting migrations across continents could assist diverse stakeholders in utilizing migrant services, reducing disservices, or mitigating human-wildlife conflicts. Radars are powerful tools for such monitoring as they can assess directional intensities, such as migration traffic rates, and biomass transported. Currently, however, most radar applications are local or small scale and therefore substantially limited in their ability to address large-scale phenomena. As weather radars are organized into continent-wide networks and also detect "biological targets," they could routinely monitor aerial migrations over the relevant spatial scales and over the timescales required for detecting responses to environmental perturbations. To tap these unexploited resources, a concerted effort is needed among diverse fields of expertise and among stakeholders to recognize the value of the existing infrastructure and data beyond weather forecasting. PMID- 29599539 TI - Freshwater Megafauna: Flagships for Freshwater Biodiversity under Threat. AB - Freshwater biodiversity is highly threatened and is decreasing more rapidly than its terrestrial or marine counterparts; however, freshwaters receive less attention and conservation investment than other ecosystems do. The diverse group of freshwater megafauna, including iconic species such as sturgeons, river dolphins, and turtles, could, if promoted, provide a valuable tool to raise awareness and funding for conservation. We found that freshwater megafauna inhabit every continent except Antarctica, with South America, Central Africa, and South and Southeast Asia being particularly species rich. Freshwater megafauna co-occur with up to 93% of mapped overall freshwater biodiversity. Fifty-eight percent of the 132 megafauna species included in the study are threatened, with 84% of their collective range falling outside of protected areas. Of all threatened freshwater species, 83% are found within the megafauna range, revealing the megafauna's capacity as flagship and umbrella species for fostering freshwater conservation.

AB - Broadening the participation of women in science, technology, engineering, and mathematical (STEM) fields is more than a social-justice issue; diversity is paramount to a thriving national research agenda. However, women face several obstacles to fully actualizing their research potential. Enhancing the research capacity and opportunity of women faculty requires purposeful changes in university practice. Therefore, we designed an intervention, a grant-writing bootcamp informed by self-determination theory (Deci and Ryan 2012), to support the participants' feelings of relatedness, autonomy, and competence. Three grant writing bootcamps were run over an 18-month period. Using a pre- and post-test design over the span of 1 year (and contrasting results with a comparison sample who were not part of the intervention) showed that the women participating in the grant-writing bootcamp significantly increased the number of external grants submitted, the number of proposals led as principal investigator, the number of external grants awarded, and the amount of external funding dollars awarded. PMID- 29599542 TI - Google Haul Out: Earth Observation Imagery and Digital Aerial Surveys in Coastal Wildlife Management and Abundance Estimation. AB - As the sampling frequency and resolution of Earth observation imagery increase, there are growing opportunities for novel applications in population monitoring. New methods are required to apply established analytical approaches to data collected from new observation platforms (e.g., satellites and unmanned aerial vehicles). Here, we present a method that estimates regional seasonal abundances for an understudied and growing population of gray seals (Halichoerus grypus) in southeastern Massachusetts, using opportunistic observations in Google Earth imagery. Abundance estimates are derived from digital aerial survey counts by adapting established correction-based analyses with telemetry behavioral observation to quantify survey biases. The result is a first regional understanding of gray seal abundance in the northeast US through opportunistic Earth observation imagery and repurposed animal telemetry data. As species observation data from Earth observation imagery become more ubiquitous, such methods provide a robust, adaptable, and cost-effective solution to monitoring animal colonies and understanding species abundances.

AB - Empirical investigations of the impacts of anthropogenic stressors on marine organisms are typically performed under controlled laboratory conditions, onshore mesocosms, or via offshore experiments with realistic (but uncontrolled) environmental variation. These approaches have merits, but onshore setups are generally small sized and fail to recreate natural stressor fields, whereas offshore studies are often compromised by confounding factors. We suggest the use of flooded shipbuilding docks to allow studying realistic exposure to stressors and their impacts on the intra- and interspecific responses of animals. Shipbuilding docks permit the careful study of groups of known animals, including the evaluation of their behavioral interactions, while enabling full control of the stressor and many environmental conditions. We propose that this approach could be used for assessing the impacts of prominent anthropogenic stressors, including chemicals, ocean warming, and sound. Results from shipbuilding-dock studies could allow improved parameterization of predictive models relating to the environmental risks and population consequences of anthropogenic stressors.

Recent innovations to involve citizen scientists in digitization increase awareness of the value of biodiversity specimens; advance science, technology, engineering, and math literacy; and build sustainability for digitization. In support of these activities, we launched the first global citizen-science event focused on the digitization of biodiversity specimens: Worldwide Engagement for Digitizing Biocollections (WeDigBio). During the inaugural 2015 event, 21 sites hosted events where citizen scientists transcribed specimen labels via online platforms (DigiVol, Les Herbonautes, Notes from Nature, the Smithsonian Institution's Transcription Center, and Symbiota). Many citizen scientists also contributed off site. In total, thousands of citizen scientists around the world completed over 50,000 transcription tasks. Here, we present the process of organizing an international citizen-science event, an analysis of the event's effectiveness, and future directions-content now foundational to the growing WeDigBio event. PMID- 29599549 TI - Urban Mind: Using Smartphone Technologies to Investigate the Impact of Nature on Mental Well-Being in Real Time. AB - Existing evidence on the beneficial effects of nature on mental health comes from studies using cross-sectional designs. We developed a smartphone-based tool (Urban Mind; www.urbanmind.info) to examine how exposure to natural features within the built environment affects mental well-being in real time. The tool was used to monitor 108 individuals who completed 3013 assessments over a 1-week period. Significant immediate and lagged associations with mental well-being were found for several natural features. These associations were stronger in people with higher trait impulsivity, a psychological measure of one's tendency to behave with little forethought or consideration of the consequences, which is indicative of a higher risk of developing mental-health issues. Our investigation suggests that the benefits of nature on mental well-being are time-lasting and interact with an individual's vulnerability to mental illness. These findings have potential implications from the perspectives of global mental health as well as urban planning and design. PMID- 29599551 TI - CVMA: 70 and going strong.

AB - This study determined whether mineral concentrations in the hooves of cattle with toe tip necrosis syndrome (cases) differed from those of cattle dying of all other causes (controls). Samples were collected over a 2-year period from 16 different feedlots and analyzed for 8 minerals [cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), and zinc (Zn)]. Mineral concentrations in the hoof wall and solar horn of the same hoof were poorly correlated; Se was the most correlated (rho = 0.865; P < 0.001), while Mg (rho = 0.465; P < 0.001) and Zn (rho = 0.157; P = 0.053) were the least correlated. The cases had significantly lower Mg concentrations in both the hoof wall and solar horn tissue compared to the control subjects. For every 10 ppm decrease in Mg, the odds of a diagnosis of toe tip necrosis syndrome (TTNS) increased by 1.13 times for the hoof wall (P = 0.002) and 1.21 times for solar horn (P < 0.001). PMID- 29599556 TI - Evaluation of post-operative pain after active desufflation at completion of laparoscopy in mares undergoing ovariectomy. AB - The cause of transient post-operative pain in a subset of horses undergoing laparoscopy is unclear. The objective of this study was to evaluate if residual pneumoperitoneum is associated with transient post-operative pain in mares undergoing ovariectomy. Thirty-eight mares undergoing routine standing laparoscopic ovariectomy were randomly allocated into 2 groups. At the completion of laparoscopy, either the abdominal cavity was actively desufflated or the cannulas were opened to achieve ambient pressure before incisional closure. Assessments were performed for 18 hours after surgery using a validated visceral/somatic pain scale for horses. Overall, pain was minimal in both groups (median score 2/39) post-surgery. Active desufflation of the pneumoperitoneum at the completion of laparoscopy approached statistical significance (P = 0.07) in decreasing pain at 12 hours after laparoscopy. However, effects of active desuffation were not significant throughout the monitored 18-hour post-surgery period. We conclude that the decision to actively desufflate at the completion of laparoscopy should be based on surgeon's preference.

AB - Canadian Animal Health Institute (CAHI) data are used for provincial, national, and international comparisons of Canadian animal antimicrobial use. The objectives of this paper were to: i) use CAHI and British Columbia (BC) antimicrobial distribution data to group BC antimicrobial sales into the following BC retail distribution channels: over-the-counter retail outlets, livestock and poultry feed mills, aquaculture feed mills, livestock and poultry veterinarians, and companion animal veterinarians; and ii) to validate the CAHI BC distribution data and BC's antimicrobial distribution data from 2012 to 2014. Annual total antimicrobial distribution and distribution by antimicrobial class were presented for each distribution channel. The distribution of medically important antimicrobials for production animals was validated, the distribution of ionophores was not. A lack of data precluded any attempt to validate the distribution of antimicrobials for companion animals. Each distribution channel typically experienced substantial fluctuations in total antimicrobial use and use by antibiotic class at least once over the 3-year period. The validated data are useful for evidence-based analysis of a proposed Canadian policy requiring a veterinary prescription for all medically important antimicrobials.

AB - This study reports short- and long-term clinical outcomes following excision arthroplasty in 7 small breed dogs with shoulder pathology. Lameness and pain were scored before surgery, and reassessed at short- and long-term follow-ups with measurements of range of motion (ROM), scapulo-humeral angles of extension (EA) and flexion (FA), and muscle girth (MG) of the operated and contralateral limbs. All dogs improved clinically for lameness and pain. Range of motion, EA, and FA of the operated limb were not significantly different compared with the contralateral limb at short-term follow-up, but ROM and EA were significantly decreased at long-term examination. Muscle girth was not significantly different than the contralateral limb. Radiographic re-evaluations showed bony proliferation around osteotomies without interosseous union in most dogs and all owners were satisfied with the surgery outcome. Excision arthroplasty seems to be an effective treatment for chronic shoulder pathologies in small dogs. Range of motion and EA were decreased and a mild lameness remained present at long-term follow-up. PMID- 29599560 TI - Veterinary care across Canada: Average provincial fees in 2017. PMID- 29599559 TI - Characteristics of parasitic egg shedding over a 1-year period in foals and their dams in 2 farms in central Saskatchewan. AB - The goals of this study were to report the seasonal shedding patterns of strongyle and Parascaris spp. eggs in repeated fecal samples for mares (n = 38) and foals (n = 39), and to evaluate the efficacy of ivermectin treatment in mares from 2 selected horse breeding farms in central Saskatchewan. Median strongyle fecal egg counts (FEC) peaked in July and August in adult horses. The farms differed significantly (P = 0.0005) in regard to strongyle shedding categories (< 200; 200 to 500; and > 500 eggs/g) over time, but for each individual horse (both farms combined) these categories did not differ over time (P = 0.13) on samples collected in grazing season. When evaluating 3 samples collected fall, summer and fall in 2 consecutive grazing seasons, 94% of horses that shed < 200 eggs/g on 2 initial samples, remained in the same category on the third sample. Mares on each farm didn't differ statistically in shedding categories when comparing September samples from 2 consecutive years (Farm A: P = 0.56, Farm B: P = 0.06). Peak strongyle shedding occurred late fall in the first year of life for foals on Farm A, and in July in the second year of life for foals on Farm B. Parascaris spp. FEC were greatest in foals <= 6 months of age, with peak observed when foals were 5 to 6 months old. Ivermectin was 100% effective at reducing strongyle FEC 2 weeks after treatment in adult horses. Horses in Saskatchewan had relatively high strongyle shedding levels, which were significantly different between the farms, and high prevalence of Oxyuris equi. Strongyle shedding consistency was observed for FECs collected from mares in grazing season (July to September).

In particular, the gases and smoke produced both during the smoldering stages of fires leading to ignition and during the advanced flaming stages of a developing fire serve to contaminate the surrounding atmosphere, potentially producing elevated levels of toxicity and high levels of smoke obscuration that render the environment untenable. In underground mines, these hazards may be exacerbated by the existing forced ventilation that can carry the gases and smoke to locations far-removed from the fire location. Clearly, materials that require high temperatures (above 1400 K) and that exhibit low mass loss during thermal decomposition, or that require high heat fluxes or heat transfer rates to ignite represent less of a hazard than materials that decompose at low temperatures or ignite at low levels of heat flux. In order to define and quantify some possible parameters that can be used to assess these hazards, small-scale laboratory experiments were conducted in a number of configurations to measure: 1) the toxic gases and smoke produced both during non-flaming and flaming combustion; 2) mass loss rates as a function of temperature to determine ease of thermal decomposition; and 3) mass loss rates and times to ignition as a function of incident heat flux. This paper describes the experiments that were conducted, their results, and the development of a set of parameters that could possibly be used to assess the overall fire hazard of combustible materials using small scale laboratory experiments. PMID- 29599566 TI - Show Yourself, Asparaginase: An Enzymatic Reaction Explained through a Hands-On Interactive Activity. AB - Determining the catalytic activity of an enzyme can be the perfect method for its identification, for example during purification procedures or for isolation purposes. Herein, we used a pharmaceutically relevant protein to bring the concept of enzymatic activity to the classroom. We designed a hands-on interactive activity in which a medically relevant enzyme, asparaginase, was distinguished from a nonenzymatic protein based on its specific enzymatic activity. The experiment was carried out in the classroom, designed to impact different educational levels from elementary to high school. Our main purposes were to promote the emerging field of protein-based drugs as a source of scientific careers in bionanotechnology and to show the students an image of a "scientist" as that of a common and educated person working in an exciting profession. In addition of being inexpensive, this activity proved to be adaptable for various educational levels and can be easily implemented in different scenarios, for example, scientific fairs, some schools, and so forth. PMID- 29599567 TI - Evaluation of Blob Theory for the Diffusion of DNA in Nanochannels. AB - We have measured the diffusivity of lambda-DNA molecules in approximately square nanochannels with effective sizes ranging from 117 nm to 260 nm at moderate ionic strength. The experimental results do not agree with the non-draining scaling predicted by blob theory. Rather, the data are consistent with the predictions of previous simulations of the Kirkwood diffusivity of a discrete wormlike chain model, without the need for any fitting parameters. PMID- 29599568 TI - Assessing the Accuracy of Multi-Temporal Built-Up Land Layers across Rural-Urban Trajectories in the United States. AB - Global data on settlements, built-up land and population distributions are becoming increasingly available and represent important inputs to a better understanding of key demographic processes such as urbanization and interactions between human and natural systems over time. One persistent drawback that prevents user communities from effectively and objectively using these data products more broadly, is the absence of thorough and transparent validation studies. This study develops a validation framework for accuracy assessment of multi-temporal built-up land layers using integrated public parcel and building records as validation data. The framework is based on measures derived from confusion matrices and incorporates a sensitivity analysis for potential spatial offsets between validation and test data as well as tests for the effects of varying criteria of the abstract term built-up land on accuracy measures. Furthermore, the framework allows for accuracy assessments by strata of built-up density, which provides important insights on the relationship between classification accuracy and development intensity to better instruct and educate user communities on quality aspects that might be relevant to different purposes. We use data from the newly-released Global Human Settlement Layer (GHSL), for four epochs since 1975 and at fine spatial resolution (38m), in the United States for a demonstration of the framework. The results show very encouraging accuracy measures that vary across study areas, generally improve over time but show very distinct patterns across the rural-urban trajectories. Areas of higher development intensity are very accurately classified and highly reliable. Rural areas show low degrees of accuracy, which could be affected by misalignment between the reference data and the data under test in areas where built-up land is scattered and rare. However, a regression analysis, which examines how well GHSL can estimate built-up land using spatially aggregated analytical units, indicates that classification error is mainly of thematic nature. Thus, caution should be taken in using the data product in rural regions. The results can be useful in further improving classification procedures to create measures of the built environment. The validation framework can be extended to data-poor regions of the world using map data and Volunteered Geographic Information.

AB - This paper examines patterns of Hispanic concentrated poverty in traditional, new, and minor destinations. Using data from 2010 to 2014 from the American Community Survey, we find that without controlling for group characteristics, Hispanics experience a lower level of concentrated poverty in new destinations compared to traditional gateways. Metropolitan level factors explain this difference, including ethnic residential segregation, the Hispanic poverty rate, and the percentage of Hispanics who are foreign born. Overall, this study sheds new light on the Hispanic geographic dispersal in the United States and offers support for the argument that the Hispanic settlement into new destinations is associated with lower levels of concentrated poverty.

AB - Now in its 17th year of operation, the Enhanced Thematic Mapper + (ETM+), on board the Landsat-7 satellite, continues to systematically acquire imagery of the Earth to add to the 40+ year archive of Landsat data. Characterization of the ETM+ on-orbit radiometric performance has been on-going since its launch in 1999. The radiometric calibration of the reflective bands is still monitored using on board calibration devices, though the Pseudo-Invariant Calibration Sites (PICS) method has proven to be an effect tool as well. The calibration gains were updated in April 2013 based primarily on PICS results, which corrected for a change of as much as -0.2%/year degradation in the worst case bands. A new comparison with the SADE database of PICS results indicates no additional degradation in the updated calibration. PICS data are still being tracked though the recent trends are not well understood. The thermal band calibration was updated last in October 2013 based on a continued calibration effort by NASA/Jet Propulsion Lab and Rochester Institute of Technology. The update accounted for a 0.31 W/m2 sr MUm bias error. The updated lifetime trend is now stable to within +/- 0.4K. PMID- 29599571 TI - Gender Inequity Associated with Increased Child Physical Abuse and Neglect: a Cross-Country Analysis of Population-Based Surveys and Country-Level Statistics. AB - Gender inequity is proposed as a societal-level risk factor for child maltreatment. However, most cross-national research examining this association is limited to developing countries and has used limited measures of gender inequity and child homicides as a proxy for child maltreatment. To examine the relationship between gender inequity and child maltreatment, we used caregivers' reported use of severe physical punishment (proxy for physical abuse) and children under 5 left alone or under the care of another child younger than 10 years of age (supervisory neglect) and three indices of gender inequity (the Social and Institutional Gender Index, the Gender Inequality Index, and the Gender Gap Index) from 57 countries, over half of which were developing countries. We found all three gender inequity indices to be significantly associated with physical abuse and two of the three to be significantly associated with neglect, after controlling for country-level development. Based on these findings, efforts to prevent child abuse and neglect might benefit from reducing gender inequity. PMID- 29599573 TI - Health Consequences of Poor Oral Health? PMID- 29599572 TI - Polymeric dental composites based on remineralizing amorphous calcium phosphate fillers. AB - For over two decades we have systematically explored structure-composition property relationships of amorphous calcium phosphate (ACP)-based polymeric dental composites. The appeal of these bioactive materials stems from their intrinsic ability to prevent demineralization and/or restore defective tooth structures via sustained release of remineralizing calcium and phosphate ions. Due to the compositional similarity of the ACP to biological tooth mineral, ACP based composites should exhibit excellent biocompatibility. Research described in this article has already yielded remineralizing sealants and orthodontic adhesives as well as a prototype root canal sealer. Our work has also contributed to a better understanding on how polymer matrix structure and filler/matrix interactions affect the critical properties of these polymeric composites and their overall performance. The addition of antimicrobial compounds to the formulation of ACP composites could increase their medical and dental regenerative treatment applications, thereby benefiting an even greater number of patients. PMID- 29599574 TI - Adult Rhabdomyoma of the Tongue in a Child: Report of a Case and a Literature Appraisal. AB - Rhabdomyoma, by definition is a benign muscle tumour.. Rhabdomyomas constitute 2% of all myogenous neoplasms. This tumour is in incongruence with other benign soft tissue tumours, in that it is rarer than its malignant counterpart. They are broadly categorised as cardiac and extra-cardiac. Three different subtypes exists as 1) the adult type, 2) the fetal type and 3) the genital type, the adult type being the most common.[1] AR (Adult Rhabdomyoma) generally occurs in the 4th and 5th decade with a male predilection.[2] There have been very few presentations of this lesion in the paediatric age group. Here we present a case of lingual adult rhabdomyoma in an 11 year old girl. PMID- 29599575 TI - Detection of Hepatitis C Virus RNA in Blood and Saliva of Transfusion-Dependent Thalassemia Patients Diagnosed with Hepatitis C. AB - Background: The aim of the current study was to detect hepatitis C virus (HCV) RNA in blood and saliva of a population of patients with thalassemia who have HCV antibody in their serum. Materials and Methods: In this cross-sectional study, blood and saliva samples were collected and were analyzed with quantitative reverse transcription polymerase chain reaction (RT-PCR) for the detection of HCV RNA. In addition, liver-related blood tests were performed, and patients' medical history was recorded. Data were analyzed by independent samples t-test and Chi square with a significant level of 0.05. Results: Overall, 62 adult patients (29 males and 33 females) were included. Most (87%) of the patients had major thalassemia and genotype 1a was the most common (42%) type. HCV RNA was detected in 71 and 16% of blood and saliva samples, respectively. HCV RNA was detected more in female patients (31%) (P = 0.003) and in intermediate thalassemia (50%) (P < 0.005). The mean age of the patients with positive saliva was almost 10 years older (P < 0.001), and the mean number of blood transfusion was fewer in positive saliva group (P = 0.037). The sensitivity, specificity, and positive and negative predictive values of saliva PCR was calculated to be 18%, 88%, 80%, and 69%, respectively. Conclusion: Saliva contained HCV RNA in 16% of the assessed population. The probability of detection of HCV RNA in saliva increased in older patients, less number of blood transfusions, females and intermediate thalassemia. Saliva RT-PCR demonstrated low sensitivity and high specificity with high positive predictive value in the assessed population. PMID- 29599576 TI - Evaluation of Bond Strength and Load Deflection Rate of Multi-stranded Fixed Retainer Wires: An In-Vitro Study. AB - Background: Fixed orthodontic retainers must be well retained on the tooth surfaces, allow physiologic movement of teeth and exert minimal forces on the teeth to be retained. Previous studies analyzed the bond strength and amount of deflection caused due to the debonding force but not the magnitude of force needed for unit deformation. Aims: This study aims to evaluate and compare the bond strength and load deflection rate (LDR) of three different fixed retainer wires. Materials and Methods: The wires were divided into three Groups: A - three stranded twisted ligature wire, B - Bond-A-Braid (Reliance Orthodontics), and C - three-stranded twisted lingual retainer wire (3M Unitek). Twenty models were prepared for each group with a passive 15 mm long lingual retainer wire bonded to two lower incisors. An occlusogingival force was applied to the wire until it debonded. For LDR, three-point bending test was done at 0.5 mm deflection. These forces were measured using a Universal Instron Testing Machine. Statistical Analysis: Mean bond strength/LDR and pairwise comparisons were analyzed with one way ANOVA and Tukey's honest significant difference post hoc test, respectively. Results: Group C exhibited the highest mean bond strength and LDR of 101.17N and 1.84N, respectively. The intergroup comparisons were all statistically significant. Conclusion: Compared to the other two wire types, Group C might be better retained on the teeth due to its higher bond strength. With its relatively higher LDR value, it may resist deformation from occlusal forces, thereby reducing inadvertent tooth movement and yet remain flexible enough to allow physiologic tooth movements. PMID- 29599577 TI - Microphotographic Assessment of Enamel Surface using Self-Etching Primer and Conventional Phosphoric Acid: An In vitro Study. AB - Introduction: Conventional acid-etching method irreversibly removes several microns of enamel surface and also involves many steps. Hence, a simplified technique that minimizes enamel loss, improves adhesion procedures, prevents saliva contamination, and saves chair time, thereby producing clinically useful bond strength, would be valuable. Aim: To assess and compare the bonding mechanism of a self-etching primer (SEP) to that of phosphoric acid on enamel of the human permanent teeth by a scanning electron microscope (SEM). Materials and Methods: Thirty freshly extracted premolars were randomly divided into two groups of fifteen teeth each - the control group I (phosphoric acid) and experimental group II (self-etching primer). Brackets were bonded using Transbond XT adhesive on the buccal surfaces of the teeth after etching and priming according to their respective protocols. The teeth were then sectioned and the samples were subjected to a protocol of demineralization cycles. After complete dissolution of dental tissues, the specimens were gold sputter coated and evaluated under SEM. Results: A characteristically uniform etch pattern was seen in the resin samples of the phosphoric acid/Transbond XT primer group, which revealed increased roughness and resin tags penetrating the demineralized enamel surface, whereas with Transbond Plus SEP, a regular resin tag distribution was observed which showed less magnitude when compared with the control group. Conclusion: From the study, it was concluded that Transbond Plus SEP produced an etch pattern which was more conservative than conventional phosphoric acid system. PMID- 29599578 TI - Surface Detail Reproduction and Dimensional Stability of Contemporary Irreversible Hydrocolloid Alternatives after Immediate and Delayed Pouring. AB - Purpose: To overcome the poor dimensional stability of irreversible hydrocolloids, alternative materials were introduced. The dimensional changes of these alternatives after delayed pouring are not well studied and documented in the literature. The purpose of the study is to evaluate and compare the surface detail reproduction and dimensional stability of two irreversible hydrocolloid alternatives with an extended-pour irreversible hydrocolloid at different time intervals. Materials and Methods: All testing were performed according to the ANSI/ADA specification number 18 for surface detail reproduction and specification number 19 for dimensional change. The test materials used in this study were newer irreversible hydrocolloid alternatives such as AlgiNot FS, Algin X Ultra FS, and Kromopan 100 which is an extended pour irreversible hydrocolloid as control. The surface detail reproduction was evaluated using stereomicroscope. The dimensional change after storage period of 1 h, 24 h, and 120 h was assessed and compared between the test materials and control. The data were analyzed using one-way ANOVA and post hoc Bonferroni test. Results: Statistically significant results (P < 0.001) were seen when mean scores of the tested materials were compared with respect to reproduction of 22 MUm line from the metal block. Kromopan 100 showed statistically significant differences between different time intervals (P < 0.001) and exhibited more dimensional change. Algin-X Ultra FS proved to be more accurate and dimensionally stable. Conclusions: Newer irreversible hydrocolloid alternative impression materials were more accurate in surface detail reproduction and exhibited minimal dimensional change after storage period of 1 h, 24 h, and 120 h than extended-pour irreversible hydrocolloid impression material.

AB - Objective: The purpose of the study is to determine the prevalence of TMDs among the 12-18 years and 19-30 years patient age group requiring orthodontic treatment by using the Fonseca's questionnaire. Material and Methods: A total of 390 patients who visited the orthodontic department for treatment were asked to fill Fonseca's questionnaire. The results were analyzed for both the age groups and the percentage values were compared between males and females, different types of malocclusion and presence of TMDs. Results: In the 12-18 years age group, around 18.75% of the males and 12.28% of the females were having some degree of TMJ dysfunction. In the 19-30 years age group, around 30.32% of the females were found to have some severity of TMJ dysfunction as opposed to 19.23% of males. In the 12-18 years age group, around 11% of Class I, 16% of Class II and 50% of class III patients were having some degree of temporomandibular dysfunction. In the 19-30 years age group, the results showed that around 24% of Class I and class II patients and 50% of Class III patients presented with some degree of TMD. In the 12-18 years age group around 15% and in the 19-30 years age group, around 25% of the patients presented with some degree of TMD ranging from mild, moderate to severe. Conclusion: The study concludes that significantly more number of females presented with TMDs as compared to males in the 19-30 years age group. As the age increases the presence of TMDs also increases because of the significant presence of TMDs in the 19-30 years age group as compared to 12-18 years age group. PMID- 29599579 TI - Influence of Infected Root Dentin on the Bond Strength of a Self-adhesive Resin Cement. AB - Aim: The aim of this study was to determine the bond strength (BS) of a self adhesive resin cement to the contaminated root dentin. Materials and Methods: The crown and apical third of twenty single-rooted teeth were removed. The root canals were flared and 1-mm-thick root sections were obtained. The sections were rinsed, dried, and sterilized. The control group (n=20) was composed of one section of each third, which remained immersed in sterile trypticase soy broth (TSB) for 2 months. The other sections comprised the experimental group (n = 40) and were immersed in a suspension of Enterococcus faecalis. The culture medium was changed at every 4 days for 2 months. The sections were rinsed with distilled water, dried, and the root canal space was filled with the self-adhesive resin cement RelyXTM U200. After 24 h, the push-out test was performed and the types of interface failure were observed on a stereo microscope. Statistical Analysis: Data were statistically analyzed by the nonparametric Mann-Whitney test (alpha=5%). Results: A significant reduction was observed in the BS of resin cement to the contaminated dentin compared to the healthy dentin, for both thirds analyzed (P < 0.05). The BS was significantly greater at the cervical third compared to the middle third for specimens in the experimental group (P < 0.05). Adhesive and mixed failures were observed more frequently in specimens contaminated with E. faecalis. Conclusion: Bacterial contamination negatively infl uenced the BS of the self-adhesive resin cement to the root dentin, and there was a predominance of adhesive and mixed failures.

AB - Purpose: Osteonecrosis of the jaw (ONJ) is a rare but complicated side effect of antiresorptive medications. The aim of the study is to evaluate the dental and drug-related factors related to ONJ among patients on these drugs at a tertiary cancer center, India. Methodology: A retrospective record review of patients who received antiresorptive medication at our center from 2011 to 2014 was done. The demographic factors, type, dosage, and duration of the medication and dental history were collected, and the data were entered an analyzed using Epidata software. Results: A higher incidence of ONJ (8.1%) was noted in our sample (n = 183). Dental intervention after zoledronic acid (ZA) administration showed a statistical significance (P < 0.001). No significance (P value) was noted with respect to sex (0.78), age (0.28), median duration (0.9), and median dosage (0.9) of ZA. Conclusion: Oro-dental screening and dental monitoring shall reduce the incidence of ONJ. Within the limitations of our study, no significant relation could be pointed toward the dosage and duration of the drug and development of ONJ. PMID- 29599582 TI - Clinical Evaluation of Role of Dual Antiplatelet Therapy on Bleeding after Dental Extraction. AB - Aims and Objectives: Altered platelet function and increased bleeding time (BT) can occur with antiplatelet therapy. This study was conducted to evaluate the need for stoppage of dual antiplatelet therapy in patients undergoing dental extractions. Materials and Methods: One hundred and fifty patients indicated for dental extraction were grouped as Group I: Consisted of 75 patients on dual antiplatelet therapy and Group II: Consisted of 75 patients who have discontinued antiplatelet therapy 1 week before dental extraction. BT of all the participants was recorded before extraction procedures. Under local anesthesia, single molar tooth indicated for simple extraction was done in both the groups. Suturing along with pressure pack was done after extraction. BT after extraction was statistically checked between the groups after 1 h and 24 h using Chi-square test with P < 0.05. Results: Postoperatively, none of the patients in both the groups showed active bleeding 1 h and 24 h. No bleeding was seen in 73 patients in Group I and 78 patients in Group II after 24 h. Conclusion: This study concluded that there is no significant difference in BT in both the groups. Antiplatelet monotherapy or even antiplatelet dual therapy needs no alteration or stopped before minor oral surgical procedures. Most of the postoperative bleeding can be easily controlled by local hemostatic measures. PMID- 29599583 TI - Evaluation of Antibacterial Efficacy of Fungal-Derived Silver Nanoparticles against Enterococcus faecalis. AB - Background: The main objective of endodontic therapy is complete elimination and prevention of bacteria from the root canal system; however, it is difficult due to anatomical ramifications of root canal system and growing resistant microbes to available disinfectants. Therefore, to overcome this problem, newer antimicrobial agents have to be developed. Aims: The aim of the study was to evaluate the antibacterial efficacy of fungal-derived biosynthesized silver nanoparticles (AgNPs) against Enterococcus faecalis. Materials and Methods: Freshly prepared silver nanoparticles using the endophytic fungi Fusarium semitectum, characterized by different techniques were used to evaluate the antibacterial efficacy against E. faecalis by agar well diffusion method measuring the zone of inhibition using different concentrations of nanoparticles (AgNPs) (A [20 MUl], B [40 MUl], C [60 MUl], D [80 MUl], and E [100 MUl]), F (0.2% chlorhexidine [CHX]), G (2% CHX), H (ampicillin), and I (distilled water) were used as control groups. Statistical Analysis Used: One-way ANOVA followed by post hoc Tukey multiple comparison test was done. Results: AgNPs (100 ml) showed highest zone of inhibition 19.5 mm against E. faecalis. CHX (0.2%) 14.52 mm, CHX (2%) 20.02 mm, and ampicillin showed highest mean zone of inhibition 20.5 mm and distilled water showed no zone of inhibition. Results indicate no significant difference between E (100 MUl), G (2% CHX), and H (ampicillin) (P < 0.0001). Conclusions: Biosynthesized AgNPs exhibit efficient antibacterial activity against E. faecalis and therefore can be used as root canal irrigant or intracanal medicament for root canal disinfection.

AB - Introduction: With progressive development in the growth and function of the jaws, changes are observed in size as well as shape of the mandible, which vary on the basis of age, gender, and dental status. The objective of this study was to evaluate and assess the morphological changes of the mandible, with varying age, gender, and dental status, using panoramic radiographs. Materials and Methods: A retrospective study was conducted using digital panoramic radiographs taken by Kodak 8000c digital panoramic and cephalometric system on 150 patients, comprising fifty edentulous individuals (above 50 years of age), fifty old dentate individuals (above 50 years of age), and fifty young dentate individuals (below 25 years of age). All the mandibular measurements (gonial angle, ramus length, condylar length (CL), ramus notch depth, and cortical bone thickness) were carried out using RadiAnt DICOM VIEWER 2.2.9 (32-bit) software. The measurements were then subjected to paired t-test, Tukey's multiple post hoc procedures, and multiple linear regression analysis. Results: Descriptive statistics for all the parameters on the right and left sides of the mandible in both males and females were analyzed. A statistical significance of P < 0.05 was observed for all the variables except one variable (CL). Conclusion: In the present study, all the variables showed increased measurements in males except gonial angle, which was found to be wider in females, indicating that women tend to get affected by varying dental statuses than men. Hence, the parameters used in this study may act as good indicators for the assessment of the effect of age, gender, and dental status on mandibular morphology.

AB - Background: The shrinkage of the alveolar ridge might be minimized by the ridge preservation stages and applied alloplasts, after tooth extraction. According to studies on statins, angiogenesis and osteogenesis are observed as a topical application of these drugs. Objectives: The aim of this study is to the application of simvastatin in terms of bone regeneration of the alveolar ridge after tooth extraction. Materials and Methods: This study assessed this issue through the split-mouth method which assessed 10 dental sockets filled with simvastatin and collagen and 10 others filled just by collagen postextraction. The histological process of bone samples was observed under light microscope after 2 months at the time of fixture insertion to evaluate live and dead bone, trabecular, amorphous, and nonosteoblastic. The statistical analysis was assessed using Mann-Whitney U-test and level of significance was considered <0.05. Results: Normal bone was detected in both groups. In simvastatin group, the percentages of vital bone, amorphous, and trabecular bone were more than the other group and the percentages of dead bone and nonosteoblastic were lower, although there was no significant difference in the results. Conclusion: Based on study results, simvastatin possibly can improve the quality of osteogenesis in the jaw bone; however, further studies are necessary to definitively result.

AB - Purpose: To compare and evaluate the surface quality of silicone impression materials after ozone water disinfection. Materials and Methods: A total of 60 samples were prepared on a stainless steel die (American Dental Association specification no. 19 and International Standard of Organization - 4823). The samples were divided into four groups; each group contains 15 samples. Group A as control, Group B, C, and D disinfected with 2% glutaraldehyde, 5.25% sodium hypochlorite, and ozone water, respectively. The samples were made according to the manufacturer's instructions, and the samples were allowed to set in a thermostatically controlled water bath at 35 degrees C +/- 1 degrees C and retrieved after 10 min. The surface qualities of the samples were measured in stereomicroscope with *20 magnification. Results: The data obtained were analyzed using Chi-square test, and the "P" value was calculated. The results showed that there were no differences in the surface quality among the Groups A, C, and D for addition silicone putty and light body and medium body impression materials than the Group B. Conclusion: This study concluded that ozone water disinfection showed least changes when compared to 5.25%sodium hypochloride and 2% glutaraldehyde disinfection for addition silicone putty , light body and medium body impression materials. PMID- 29599587 TI - To Evaluate the Efficacy of Topical Propolis in the Management of Symptomatic Oral Lichen Planus: A Randomized Controlled Trial. AB - Introduction: Lichen planus (LP) is a chronic inflammatory, autoimmune, mucocutaneous disease of unknown etiology. The first line of treatment for oral LP (OLP) has been corticosteroids, but because of their adverse effects, alternative therapeutic approaches are being carried out, of which the recent natural alternative is propolis. Aim: This study aims to evaluate the efficacy of topical propolis in the management of OLP. Materials and Methods: The research group consisted of 27 patients diagnosed with symptomatic OLP, among which 15 patients were in the control group and the rest 12 were in the study group. The patients in the control group received triamcinolone acetonide 0.1% (topical application) while the patients in the study group received propolis gel. Both the groups were evaluated for pain and erythema at baseline (1st visit), first follow-up (7th day), and second follow-up (14th day) using numerical rating scale and modified oral mucositis index. Results: The patients in both the study and control groups showed a statistically significant reduction (P = 0.000 for the study group and P = 0.000 for the control group) in pain and erythema scores from baseline to second follow-up visit. However, on comparison of the reduction in pain and erythema scores between the two groups, the difference was found to be statistically insignificant (P = 0.255). Statistical Analysis Used: Chi-square and Cramer's V test were used. Conclusion: The topical propolis was found to be of comparative effectiveness with respect to triamcinolone acetonide 0.1% in the management of OLP. PMID- 29599588 TI - Antimicrobial Efficacy of Octenidine Hydrochloride and Calcium Hydroxide with and Without a Carrier: A Broth Dilution Analysis. AB - Background: An efficient antimicrobial agent action is required for a predetermined time period for absolute elimination of root canal microbes. Till date, there is limited or no data on the antimicrobial effect of octenidine as an intracanal medicament with chitosan (CTS) as a carrier against Candida albicans and Enterococcus faecalis. Aim: The aim of this microbiological study was to compare the antimicrobial efficacy of octenidine hydrochloride (OHC) and calcium hydroxide (Ca[OH]2) as intracanal medicaments, both independently and along with CTS as a carrier molecule against the common resistant endodontic pathogens. Materials and Methods: A total of 160 single-rooted anterior teeth were selected, root canal preparation was done, and teeth were divided into two groups and contaminated with C. albicans and E. faecalis, which were further divided into four test groups each according to intracanal medicaments used. CTS was used as a vehicle for OHC and Ca(OH)2 and antimicrobial assessment was performed on day 2 and day 7 following broth dilution method. Dentine samples were collected after each time interval, and the number of colony-forming units was determined. Results: All four medicaments used in this study showed antifungal and antibacterial activity that diminished from day 2 to day 7. Group I (OHC alone) and Group IV (Ca[OH]2 alone) showed significant antimicrobial activity against C. albicans and E. faecalis, respectively, than the other groups. Conclusion: A combination of OHC + CTS and Ca(OH)2+ CTS produced inferior results than that of the medicaments used alone. PMID- 29599589 TI - Direct Linear Measurement of Root Dentin Thickness and Dentin Volume Changes with Post Space Preparation: A Cone-Beam Computed Tomography Study. AB - Aim: The purpose of the present study was direct linear measurement of dentin thickness and dentin volume changes for post space preparation with cone-beam computed tomography (CBCT). Materials and Methods: Ten maxillary central incisors were scanned, before and after root canal and post space preparation, with Orthophos XG three-dimensional hybrid unit. Thirteen axial section scans of each tooth from orifice to apex and dentin thickness for buccal, lingual, mesial, and distal were measured using proprietary measuring tool and thereafter subjected to statistical analysis. Furthermore, dentin volume was evaluated using ITK-SNAP software. Results: There was statistically significant difference between the dentin thickness in pre- and postinstrumentation (paired t-test) and also between different groups (one-way ANOVA). In the shortest post length of 4.5mm the post space preparation resulted in 2.17% loss of hard tissue volume, where as 11mm longest post length post space preparation resulted in >40% loss of hard tissue volume. Conclusion: CBCT axial section scan for direct measurements of root dentin thickness can be guideline before and after post space preparation for selection of drill length and diameter. PMID- 29599590 TI - Correlation between Dentofacial Esthetics and Mental Temperament: A Clinical Photographic Analysis Using Visagism. AB - Background: "Visagism," a proposed novel concept, makes it possible for the patients to express the desirable emotions and personality traits, through their smile. According to this concept, clinicians can design a smile that blends with the patient's physical appearance, personality, and desires. Aim: To establish a relation, if any, between the smile pattern (dentofacial esthetics determined by three parameters, i.e., tooth form, long axes of maxillary anterior teeth, and connection line between embrasure) and the personality traits (four mental temperaments) through the concept of visagism. Settings and Design: A total of 190 participants aged between 20 and 38 years from a dental college were selected for the study. Materials and Methods: The temperaments of the participants were identified using a self-reporting questionnaire. The photographs of frontal view of teeth in centric occlusion of the participants were captured, and their tooth forms, long axes, and embrasure lines were drawn using photograph editing software. The type of temperament obtained from the questionnaire for each participant was compared with that obtained from photographic evaluation. Statistical Analysis Used: The obtained data were statistically analyzed by applying Kappa statistics for kappa measure of agreement. Results: There was no agreement between temperaments derived through questionnaire and those temperaments obtained from the photographic analysis. Conclusion: Although the concept of combining the principles of smile design and mental temperaments through visagism is an appreciable idea, it lacks a practical approach to create a personalized smile for each patient by including mental temperaments at present stage. PMID- 29599591 TI - Comparison of Tentative Radiographic Working Length with and without grid Versus Electronic Apex Locator. AB - : The apical termination of obturation is the most important factor influencing the success of root canal treatment (RCT). Working length (WL) is the key element in achieving this. Aim: The aim of this study is to compare and evaluate the preoperative estimated WL with conventional radiograph and with grid radiograph, with reference to electronic apex locator (EAL) in single-rooted teeth. Settings and Design: Thirty permanent anterior teeth with complete root formation indicated for RCT were included in this study. Materials and Methods: Conventional radiograph (Group 1) and conventional radiograph with external grid (Group 2) were made before access opening. WL with EAL (Group 3) was determined after access opening. Statistical Analysis: The statistical package for the social sciences (SPSS) version 16.0 (SPSS Inc., Chicago, IL, USA) was used to compare the WLs of three groups, and the statistical significance was considered to be P <= 0.05. ANOVA, post hoc test were made to measure the intergroup comparison, and Pearson correlation values were obtained. Results and Conclusion: The results of the study showed a higher correlation between grid WL and apex locator WL than conventional WL and apex locator WL. Preoperative metrics with radiographic grid along with the apex locator is a better measuring tool compared to the conventional radiographic WL in a single-rooted tooth.

AB - Introduction: Tumor necrosis factor-alpha (TNF-alpha) is an important proinflammatory cytokine that regulates the early phase of inflammation reaction during orthodontic tooth movement. The aim of the present study was to compare TNF-alpha concentrations in the gingival crevicular fluid (GCF) between preadjusted edgewise appliance (PEA) and self-ligating (SL) systems during the early leveling stage of orthodontic treatment. Materials and Methods: Eighteen patients (aged 15-35 years) who participated in this study were divided into two experimental groups (PEA and SL) and control group (without orthodontic treatment). The GCF was taken at five sites in the maxilla anterior teeth from each participant just before bracket bonding and at 1, 24, and 168 h after the initiation of tooth movement. Cytokine levels were determined through ELISA. Results: The concentration of TNF-alpha was significantly higher in the experimental groups than in the control group at 24 h after force application. TNF-alpha levels were significantly decreased at 168 h after force application in the PEA group. Meanwhile, in the SL group, the level of TNF-alpha at 168 h was still increased, although there was no statistically significant difference. Conclusion: TNF-alpha concentration was increased at 1 h and 24 h after orthodontic force application in both the PEA and SL groups. In the PEA group, TNF-alpha concentration was significantly decreased at 168 h, meanwhile in the SL group, this value remained increased at this time point. The differences in TNF alpha concentration between the PEA and SL groups may be caused by their different types of brackets, wires, and ligation methods.

Conclusion: The study attempts to bring the prevailing ethical challenges in oral health care practice in Indian scenario. PMID- 29599594 TI - Evaluation of Low-Level Laser Therapy on Orthodontic Tooth Movement: A Randomized Control Study. AB - Background: Fixed orthodontic treatment is time-consuming procedure. Pain is usually associated with orthodontic treatment. The aim of the present study was to evaluate the role of low-level laser therapy (LLLT) on orthodontic tooth movement (OTM) duration and pain perception. Materials and Methods: This randomized double-blind splint-mouth controlled clinical study includes 20 (8 males and 12 females) orthodontic patients requiring bilateral canine retraction. Time taken for canine retraction with LLLT (Group A) over control (Group B) quadrant on the same patient was assessed along with pain experience using facial pain scale. The data were tabulated and statistically evaluated using SPSS 20 for windows (Microsoft, Chicago, IL, USA) and t-test with P < 0.05. The difference in pain was evaluated with Wilcoxon signed-rank test. Results: There was no difference in values for age and sex of patient for tooth movement and pain (P > 0.05). There was statistically significant decrease in rate of canine retraction in Group A compared to Group B. There was statistically significant difference for maxillary and mandibular arches in Group A whereas it was not significant in Group B. Pain experience was statistically significant till 2nd day, and after 3rd day, it was not significant between the groups. Conclusion: LLLT can reduce the fixed OTM timing and pain experience. PMID- 29599595 TI - Non-Hodgkin's Lymphoma of the mandible in HIV patient - A Rare Case Report. AB - Non-Hodgkin's lymphoma (NHL) is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds. Clinically, they may imitate a dental infection with symptoms of pain and discomfort. A delay in diagnosis may lead to a poor prognosis. Herewith, we present a case of NHL on the lower-right mandible in a 40-year-old male. A correlation of clinical findings, radiological examination, and histopathological examination enabled us in early diagnosis and differentiating it from other similar conditions, thus aiding in initiation of prompt treatment. PMID- 29599596 TI - Diode Laser and Periodontal Regeneration-Assisted Management of Implant Complications in Anterior Maxilla. AB - Dental implant is being considered successful if the patient is pleased with both of its functional and esthetic outcome. As implant complications (such as peri implantitis, inappropriate implant position, wrong angulation, and implant location too close to anatomical structures) have been frequently encountered in dental practice, therefore, thorough knowledge to manage such complications is the key prerequisite to prevent the failure of implant. The present case report discussed the etiology, diagnosis of early peri-implantitis, and periodontal abscess with their successful management through periodontal regeneration and diode laser-assisted therapy. PMID- 29599597 TI - Prosthetic Rehabilitation of Hemimandibulectomy Defect with Removable Partial Denture Prosthesis Using an Attachment-Retained Guiding Flange. AB - The restoration of normal function and esthetics is often challenging in the prosthetic rehabilitation of patients with hemimandibulectomy defects due to unstable occlusion and mandibular deviation. The extensive period of time for completion of healing of the reconstructed mandible through reconstructive plastic surgery and/or implant-assisted prosthesis may compromise the masticatory function by causing delay in the fabrication of definitive prosthesis. This case report describes a novel technique for the construction of customized attachment retained mandibular guiding flange prosthesis for immediate rectification of the frontal plane rotation occurring after hemimandibulectomy. PMID- 29599598 TI - Gingival Veneer Used as Prosthetic Solution for Esthetic-Compromised Malpositioned Dental Implant. AB - Implant therapy has become a common practice and esthetic demands have tremendously increased, especially in the replacement of anterior teeth in patients with a high lip line. This report presents a gingival veneer as a viable treatment modality to mask peri-implant marginal gingival defects. An impression of the upper arch was made and the gingival veneer was waxed, and clinical confirmation was obtained, followed by laboratory processing, finishing, and polishing. After installing, it adapted to the proximal niches and exhibited good stability. A gingival veneer can be a feasible alternative with excellent esthetic results, when indicated and correctly executed to mask possible defects in the peri-implant marginal gingiva associated with a malpositioned single dental implant.

AB - Amelogenesis imperfecta is a genetic condition affecting the teeth resulting in aberrations of the structure and clinical appearance of enamel. The treatment of amelogenesis imperfecta involves a multidisciplinary treatment approach requiring a comprehensive examination, diagnosis, and effective treatment planning strategy along with satisfaction of patient-related factors. The clinical case described here involves judicious involvement of different disciplines to formulate a treatment plan best suitable to confirm with the patient's needs and expectations, at the same time maintaining the integrity and harmony of associated hard and soft tissues. PMID- 29599600 TI - An Enigmatic Clinical Presentation of Plasma Cell Granuloma of the Oral Cavity. AB - Plasma cell granuloma is a rare benign lesion characterized by the infiltration of plasma cells; primarily occurring in the lungs. It is also seen to occur in the brain, kidney stomach, heart, and so on but its intraoral occurrence is a rarity. This case report represents one of the uncommon locations in the oral cavity affected by plasma cell granuloma, its clinical and histological features, and establishes the differential diagnosis with other malignant or benign disease entities and planning the treatment accordingly. This report discusses the diagnostic enigma and the associated terminology of plasma cell granulomas and reinforces the need for performing biopsy and a histopathological or immune histochemical study, irrespective of the clinical features and clinical diagnosis of the lesion. In this case a 52-year-old female, presented with gingival enlargement in the mandibular anterior region, treated by excisional biopsy. Histological evaluation revealed plasma cell infiltrates in the connective tissue. The immune-histochemistry revealed kappa and lambda light chains with a polyclonal staining pattern, which confirmed the diagnosis of plasma cell granuloma. PMID- 29599601 TI - Endodontic Management of Radix Entomolaris in Second Molar. AB - The presence of radix entomolaris (RE) in a mandibular first molar is a common occurrence, which accounts for 0.2%-32% of the population, but the presence of RE in a mandibular second molar is a rare occurrence in our ethnic group. This presence of additional root can lead to difficulties during endodontic treatment. A thorough knowledge of anatomy is necessary for the success of endodontic treatment. This article presents a review on clinical approach and a case series on the detection and management of RE on mandibular second molar. RE was identified using Same lingual opposite buccal (SLOB) technique with preoperative radiograph, modifying the access cavity preparation, locating the canals followed by cleaning, and shaping of canals with nickel-titanium instruments. Obturation was done with respective master cones and AH + resin sealer. PMID- 29599602 TI - PGI Bracket Positioner: A Novel Combination of Reverse Bracket Tweezer and Positioning Gauze. AB - The accurate bracket positioning is essential for the expression of the bracket system that affects the treatment outcome considerably and is also essential for good functional occlusion as well as facial esthetics. The proper alignment cannot be achieved without proper bracket positioning. Thus, the brackets positioning devices are an integral part of orthodontic armamentarium. Here, we present a new innovation that provides a unique combination of reverse bracket tweezer and positioner and hence is very helpful in precise vertical positioning of brackets with increased efficiency. PMID- 29599603 TI - Sleeve Push Technique: A Novel Method of Space Gaining. AB - Space gaining is frequently required in orthodontics. Multiple loops were initially used for space gaining and alignment. The most common used mechanics for space gaining is the use of nickel-titanium open coil springs. The disadvantage of nickel-titanium coil spring is that they cannot be used until the arches are well aligned to receive the stiffer stainless steel wires. Therefore, a new method of gaining space during initial alignment and leveling has been developed and named as sleeve push technique (SPT). The nickel-titanium wires, i.e. 0.012 inches and 0.014 inches along with archwire sleeve (protective tubing) can be used in a modified way to gain space along with alignment. This method helps in gaining space right from day 1 of treatment. The archwire sleeve and nickel-titanium wire in this new SPT act as a mutually synergistic combination and provide the orthodontist with a completely new technique for space opening. PMID- 29599605 TI - Cell culture-adaptive mutations in hepatitis C virus promote viral production by enhancing viral replication and release. AB - AIM: To explore hepatitis C virus (HCV) adaptive mutations or combinations thereof responsible for enhanced viral production and investigate the underlying mechanisms. METHODS: A series of plasmids with adaptive mutations were constructed. After the plasmids were transfected into Huh7.5 cells, we determined the infectious HCV particle titers by NS5A immunofluorescence assays, and detected HCV RNA replication by real-time PCR and protein expression by Western blot. Then we carried out immunoblotting of supernatants and cell lysates with anti-NS3 to analyze the virus release level. In addition, co-localization of lipid droplets (LDs) with NS5A was measured using confocal laser scanning microscopy. The ratio between the p56 and p58 phosphoforms of NS5A was analyzed further. RESULTS: The plasmids named JFH1-mE2, JFH1-mp7, JFH1-mNS4B, JFH1-mNS5A, JFH1-mE2/NS5A, JFH1-mp7/NS5A, JFH1-mNS4B/NS5A, JFH1-mE2/p7/NS5A, and mJFH1 were constructed successfully. This study generated infectious HCV particles with a robust titer of 1.61 * 106 focus-forming units (FFUs)/mL. All of the six adaptive mutations increased the HCV particle production at varying levels. The NS5A (C2274R, I2340T, and V2440L) and p7 (H781Y) were critical adaptive mutations. The effect of NS5A (C2274R, I2340T, and V2440L), p7 (H781Y), and NS4B (N1931S) on infectious HCV titers was investigated by measuring the HCV RNA replication, protein expression, and virion release. However, the six adaptive mutations were not required for the LD localization of NS5A proteins or the phosphorylation of NS5A. CONCLUSION: In this study, we generated infectious HCV particles with a robust titer of 1.61 * 106 FFUs/mL, and found that the viral replication and release levels could be enhanced by some of the adaptive mutations. PMID- 29599604 TI - Review article: Update on current and emergent data on hepatopulmonary syndrome. AB - Hepatopulmonary syndrome (HPS) is a frequent pulmonary complication of end-stage liver disease, characterized by impaired arterial oxygenation induced by intrapulmonary vascular dilatation. Its prevalence ranges from 4% to 47% in patients with cirrhosis due to the different diagnostic criteria applied among different studies. Nitric oxide overproduction and angiogenesis seem to be the hallmarks of a complicated pathogenetic mechanism, leading to intrapulmonary shunting and ventilation-perfusion mismatch. A classification of HPS according to the severity of hypoxemia has been suggested. Contrast-enhanced echocardiography represents the gold standard method for the detection of intrapulmonary vascular dilatations which is required, in combination with an elevated alveolar arterial gradient to set the diagnosis. The only effective treatment which can modify the syndrome's natural history is liver transplantation. Although it is usually asymptomatic, HPS imparts a high risk of pretransplantation mortality, independently of the severity of liver disease, while there is variable data concerning survival rates after liver transplantation. The potential of myocardial involvement in the setting of HPS has also gained increasing interest in recent research. The aim of this review is to critically approach the existing literature of HPS and emphasize unclear points that remain to be unraveled by future research. PMID- 29599606 TI - Serum interleukin-34 level can be an indicator of liver fibrosis in patients with chronic hepatitis B virus infection. AB - AIM: To investigate whether serum interleukin (IL)-34 levels are correlated with hepatic inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection. METHODS: In this study, serum IL-34 levels were assessed by enzyme-linked immunosorbent assay in 19 healthy controls and 175 patients with chronic HBV infection undergoing biopsy. The frequently used serological markers of liver fibrosis were based on laboratory indexes measured at the Clinical Laboratory of the Second Affiliated Hospital of Anhui Medical University. Liver stiffness was detected by transient elastography with FibroTouch. The relationships of non-invasive makers of liver fibrosis and IL-34 levels with inflammation and fibrosis were analyzed. The diagnostic value of IL-34 and other liver fibrosis makers were evaluated using areas under the receiver operating characteristic curves, sensitivity and specificity. RESULTS: Serum IL-34 levels were associated with inflammatory activity in the liver, and IL-34 levels differed among phases of chronic HBV infection (P = 0.001). By comparing serum IL 34 levels among patients with various stages of liver fibrosis determined by liver biopsy, we found that IL-34 levels >= 15.83 pg/mL had a high sensitivity of 86.6% and a specificity of 78.7% for identifying severe fibrosis (S3-S4). Furthermore, we showed that IL-34 is superior to the fibrosis-4 score, one of the serum makers of liver fibrosis, in identifying severe liver fibrosis and early cirrhosis in patients with HBV-related liver fibrosis in China. CONCLUSION: Our results indicate that IL-34, a cytokine involved in the induction of activation of profibrogenic macrophages, can be an indicator of liver inflammation and fibrosis in patients with chronic HBV infection. PMID- 29599607 TI - Model combining pre-transplant tumor biomarkers and tumor size shows more utility in predicting hepatocellular carcinoma recurrence and survival than the BALAD models. AB - AIM: To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma (HCC) patients after liver transplant. METHODS: BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein (AFP), Lens culinaris agglutinin-reactive AFP (AFP L3), and des-gamma-carboxyprothrombin (DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios (HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker based to predictive models. RESULTS: During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42 (1.18-5.00), 1.86 (0.98-3.52), and 2.83 (1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48 (1.15-1.91) and 1.59 (1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45 (1.06-1.98) and 1.38 (1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65, 0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant (S-LAD) demonstrated the highest predictive capability with c statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION: BALAD and BALAD 2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter (S-LAD). PMID- 29599608 TI - Intraoperative frozen section diagnosis of bile duct margin for extrahepatic cholangiocarcinoma. AB - AIM: To evaluate the usefulness of frozen section diagnosis (FSD) of bile duct margins during surgery for extrahepatic cholangiocarcinoma (CCA). METHODS: We retrospectively analyzed 74 consecutive patients who underwent surgery for extrahepatic CCA from 2012 to 2017, during which FSD of bile duct margins was performed. They consisted of 40 distant and 34 perihilar CCAs (45 and 55 bile duct margins, respectively). The diagnosis was classified into three categories: negative, borderline (biliary intraepithelial neoplasia-1 and 2, and indefinite for neoplasia), or positive. FSD in the epithelial layer, subepithelial layer, and total layer was compared with corresponding permanent section diagnosis (PSD) postoperatively. Then, association between FSD and local recurrence was analyzed with special reference to borderline. RESULTS: Analysis of 100 duct margins revealed that concordance rate between FSD and PSD was 68.0% in the total layer, 69.0% in the epithelial layer, and 98.0% in the subepithelial layer. The extent of remaining biliary epithelium was comparable between FSD and PSD, and more than half of the margins lost > 50% of the entire epithelium, suggesting low quality of the samples. In FSD, the rate of negative margins decreased and that of borderline and positive margins increased according to the extent of the remaining epithelium. Diagnostic discordance between FSD and PSD was observed in 31 epithelial layers and two subepithelial layers. Alteration from borderline to negative was the most frequent (20 of the 31 epithelial layers). Patients with positive margin in the total and epithelial layers by FSD demonstrated a significantly worse local recurrence-free survival (RFS) compared with patients with borderline and negative margins, which revealed comparable local RFS. Patients with borderline and negative margins in the epithelial layer by PSD also revealed comparable local RFS. These results suggested that epithelial borderline might be regarded substantially as negative. When classifying the status of the epithelial layer either as negative or positive, concordance rates between FSD and PSD in the total, epithelial, and subepithelial layers were 95.0%, 93.0%, and 98.0%, respectively. CONCLUSION: During intraoperative assessment of bile duct margin, borderline in the epithelial layer can be substantially regarded as negative, under which condition FSD is comparable to PSD. PMID- 29599609 TI - Correlation between serum vitamin B12 level and peripheral neuropathy in atrophic gastritis. AB - AIM: To explore the correlation between serum vitamin B12 level and peripheral neuropathy in patients with chronic atrophic gastritis (CAG). METHODS: A total of 593 patients diagnosed with chronic gastritis by gastroscopy and pathological examination from September 2013 to September 2016 were selected for this study. The age of these patients ranged within 18- to 75-years-old. Blood pressure, height and weight were measured in each patient, and the body mass index value was calculated. Furthermore, gastric acid, serum gastrin, serum vitamin and serum creatinine tests were performed, and peripheral nerve conduction velocity and Helicobacter pylori (H. pylori) were detected. In addition, the type of gastritis was determined by gastroscopy. The above factors were used as independent variables to analyze chronic gastritis with peripheral neuropathy and vitamin B12 deficiency risk factors, and to analyze the relationship between vitamin B12 levels and peripheral nerve conduction velocity. In addition, in the treatment of CAG on the basis of vitamin B12, patients with peripheral neuropathy were observed. RESULTS: Age, H. pylori infection, CAG, vitamin B9 and vitamin B12 were risk factors for the occurrence of peripheral nerve degeneration. Furthermore, CAG and H. pylori infection were risk factors for chronic gastritis associated with vitamin B12 deficiency. Serum vitamin B12 level was positively correlated with sensory nerve conduction velocity in the tibial nerve (R = 0.463). After vitamin B12 supplementation, patients with peripheral neuropathy improved. CONCLUSION: Serum vitamin B12 levels in patients with chronic gastritis significantly decreased, and the occurrence of peripheral neuropathy had a certain correlation. CAG and H. pylori infection are risk factors for vitamin B12 deficiency and peripheral neuropathy. When treating CAG, vitamin B12 supplementation can significantly reduce peripheral nervous system lesions. Therefore, the occurrence of peripheral neuropathy associated with vitamin B12 deficiency may be considered in patients with CAG. Furthermore, the timely supplementation of vitamin B12 during the clinical treatment of CAG can reduce or prevent peripheral nervous system lesions. PMID- 29599610 TI - Successful combination of direct antiviral agents in liver-transplanted patients with recurrent hepatitis C virus. AB - AIM: To analyze the safety and efficiency of direct-acting antiviral (DAA) regimens in liver-transplanted patients with hepatitis C virus (HCV) reinfection. METHODS: Between January 2014 and December 2016, 39 patients with HCV reinfection after liver transplantation were treated at our tertiary referral center with sofosbuvir (SOF)-based regimens, including various combinations with interferon (IFN), daclatasvir (DAC), simeprivir (SIM) and/or ledipasvir (LDV). Thirteen patients were treated with SOF + IFN +/- RBV. Ten patients were treated with SOF + DAC +/- RBV. Fiveteen patients were treated with fixed-dose combination of SOF + LDV +/- RBV. One patient was treated with SOF + SIM + RBV. Three patients with relapse were retreated with SOF + LDV + RBV. The treatment duration was 12-24 wk in all cases. The decision about the HCV treatment was made by specialists at our transplant center, according to current available or recommended medications. RESULTS: The majority of patients were IFN-experienced (29/39, 74.4%) and had a history of hepatocellular carcinoma (26/39, 66.7%) before liver transplantation. Sustained virological response at 12 wk (SVR12) was achieved in 10/13 (76.9%) of patients treated with SOF + IFN +/- RBV. All patients with relapse were treated with fixed-dose combination of SOF + LDV + RBV. Patients treated with SOF + DAC + RBV or SOF + LDV + RBV achieved 100% SVR12. SVR rates after combination treatment with inhibitors of the HCV nonstructural protein (NS)5A and NS5B for 24 wk were significantly higher, as compared to all other therapy regimens (P = 0.007). Liver function was stable or even improved in the majority of patients during treatment. All antiviral therapies were safe and well-tolerated, without need of discontinuation of treatment or dose adjustment of immunosuppression. No serious adverse events or any harm to the liver graft became overt. No patient experienced acute cellular rejection during the study period. CONCLUSION: Our cohort of liver-transplanted patients achieved high rates of SVR12 after a 24-wk course of treatment, especially with combination of NS5A and NS5B inhibitors. PMID- 29599612 TI - Fourier phase retrieval with a single mask by Douglas-Rachford algorithms. AB - The Fourier-domain Douglas-Rachford (FDR) algorithm is analyzed for phase retrieval with a single random mask. Since the uniqueness of phase retrieval solution requires more than a single oversampled coded diffraction pattern, the extra information is imposed in either of the following forms: 1) the sector condition on the object; 2) another oversampled diffraction pattern, coded or uncoded. For both settings, the uniqueness of projected fixed point is proved and for setting 2) the local, geometric convergence is derived with a rate given by a spectral gap condition. Numerical experiments demonstrate global, power-law convergence of FDR from arbitrary initialization for both settings as well as for 3 or more coded diffraction patterns without oversampling. In practice, the geometric convergence can be recovered from the power-law regime by a simple projection trick, resulting in highly accurate reconstruction from generic initialization. PMID- 29599611 TI - Daclatasvir plus asunaprevir in treatment-naive patients with hepatitis C virus genotype 1b infection. AB - AIM: To assess daclatasvir plus asunaprevir (DUAL) in treatment-naive patients from mainland China, Russia and South Korea with hepatitis C virus (HCV) genotype 1b infection. METHODS: Patients were randomly assigned (3:1) to receive 24 wk of treatment with DUAL (daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period (immediate treatment arm) or following 12 wk of matching placebo (placebo-deferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12 (SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin (70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in DUAL-treated patients compared with placebo patients during the first 12 wk (double-blind phase), and during 24 wk of DUAL in both arms combined. RESULTS: In total, 207 patients were randomly assigned to immediate (n = 155) or placebo-deferred (n = 52) treatment. Most patients were Asian (86%), female (59%) and aged < 65 years (90%). Among them, 13% had cirrhosis, 32% had IL28B non-CC genotypes and 53% had baseline HCV RNA levels of >= 6 million IU/mL. Among patients in the immediate treatment arm, SVR12 was achieved by 92% (95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate (70%). SVR12 was largely unaffected by cirrhosis (89%), age >= 65 years (92%), male sex (90%), baseline HCV RNA >= 6 million (89%) or IL28B non-CC genotypes (96%), although SVR12 was higher among patients without (96%) than among those with (53%) baseline NS5A resistance-associated polymorphisms (at L31 or Y93H). During the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving DUAL. During 24 wk of DUAL therapy (combined arms), the most common adverse events (>= 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities (alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued DUAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths. CONCLUSION: DUAL was well-tolerated during this phase 3 study, and SVR12 with DUAL treatment (92%) exceeded the historical SVR rate for peg-interferon plus ribavirin of 70%.

AB - Background: The aim of this study was to prepare and evaluate the impact of polymers on fabricating stable dexibuprofen (Dexi) nanocrystals with enhanced therapeutic potential, using a low energy, anti-solvent precipitation method coupled with molecular modelling approach. Methods: Dexi nanocrystals were prepared using antisolvent precipitation with syringe pump. Crystallinity of the processed Dexi particles was confirmed using differential scanning calorimetry and powdered X-ray diffraction and transmission electron microscopy. Dissolution of Dexi nanocrystals was compared with raw Dexi and marketed tablets. Molecular modelling study was coupled with experimental studies to rationalise the appropriate polymers for stable Dexi nanocrystals. Antinociceptive study was carried out using balb mice. Results: Combinations of hydroxypropyl methylcellulose (HPMC)-polyvinyl pyrrolidone (PVP) and HPMC-Eudragit (EUD) were shown to be very effective in producing stable Dexi nanocrystals with particle sizes of 85.0+/-2.5 nm and 90+/-3.0 nm, and polydispersity of 0.179+/-0.01, 0.182+/-0.02, respectively. The stability studies conducted for 90 days demonstrated that nanocrystals stored at 2 degrees C-8 degrees C and 25 degrees C were more stable than those at 40 degrees C. The maximum recovery of Dexi nanocrystals was observed from the formulations using the combination of HPMC-PVP and HPMC-EUD, which equated to 98% and 94% of the nominal active drug content respectively. The saturation solubility of the Dexi nanocrystals was substantially increased to 270.0+/-3.5 MUg/mL compared to the raw Dexi in water (51.0+/-2.0 MUg/mL) and stabilizer solution (92.0+/-3.0 MUg/mL). Enhanced dissolution rate (P<0.05) was observed for the Dexi nanocrystals compared to the unprocessed drug substance and marketed tablets. Dexi nanocrystals produced the analgesic effect at much lower doses (5 mg/kg) than that of control standard, diclofenac sodium (20 mg/kg) and Dexi counterparts (40 mg/kg). Conclusion: HPMC PVP and HPMC-EUD were found the best polymer combination to stabilise Dexi nanocrystals. The Dexi nanocrystals exhibited significant dissolution, solubility and analgesic effect compared to the raw Dexi and the control standard diclofenac sodium.

AB - Background: Poly-l-lysine (PLL) enhances nanoparticle (NP) uptake, but the molecular mechanism remains unresolved. We asked whether PLL may interact with negatively charged glycoconjugates on the cell surface and facilitate uptake of magnetic NPs (MNPs) by tumor cells. Methods: PLL-coated MNPs (PLL-MNPs) with positive and negative zeta-potential were prepared and characterized. Confocal and transmission electron microscopy was used to analyze cellular internalization of MNPs. A colorimetric iron assay was used to quantitate cell-associated MNPs (MNPcell). Results: Coadministration of PLL and dextran-coated MNPs in culture enhanced cellular internalization of MNPs, with increased vesicle size and numbers/cell. MNPcell was increased by eight- to 12-fold in response to PLL in a concentration-dependent manner in human glioma and HeLa cells. However, the application of a magnetic field attenuated PLL-induced increase in MNPcell. PLL coating increased MNPcell regardless of zeta-potential of PLL-MNPs, whereas magnetic force did not enhance MNPcell. In contrast, epigallocatechin gallate and magnetic force synergistically enhanced PLL-MNP uptake. In addition, heparin, but not sialic acid, greatly reduced the enhancement effects of PLL; however, removal of heparan sulfate from heparan sulfate proteoglycans of the cell surface by heparinase III significantly reduced MNPcell. Conclusion: Our results suggest that PLL-heparan sulfate proteoglycan interaction may be the first step mediating PLL-MNP internalization by tumor cells. Given these results, PLL may facilitate NP interaction with tumor cells via a molecular mechanism shared by infection machinery of certain viruses.

Therefore, it is important to clearly define nursing competency to establish a foundation for nursing education curriculum. However, while the concepts surrounding nursing competency are important for improving nursing quality, they are still not yet completely developed. Thus, challenges remain in establishing definitions and structures for nursing competency, competency levels necessary for nursing professionals, training methods and so on. In the present study, we reviewed the research on definitions and attributes of nursing competency in Japan as well as competency structure, its elements and evaluation. Furthermore, we investigated training methods to teach nursing competency. PMID- 29599615 TI - Biomimetic mineralized strontium-doped hydroxyapatite on porous poly(l-lactic acid) scaffolds for bone defect repair. AB - Introduction: poly(l-lactic acid) (PLLA) has been approved for clinical use by the US Food and Drug Administration (FDA); however, their stronger hydrophobicity and relatively fast degradation rate restricted their widespread application. In consideration of the composition of bone, the inorganic-organic composite has a great application prospect in bone tissue engineering. Many inorganic-organic composite scaffolds were prepared by directly mixing the active ingredient, but this method is uncontrolled and will lead to lack of homogeneity in the polymer matrix. Strontium (Sr) is an admirable addition to improve the bioactivity and bone induction of hydroxyapatite (HA). To our knowledge, the application of biomimetic mineralized strontium-doped hydroxyapatite on porous poly(l-lactic acid) (Sr-HA/PLLA) scaffolds for bone defect repair has never been reported till date. Biomimetic mineralized Sr-HA/PLLA porous scaffold was developed in this study. The results indicated that the Sr-HA/PLLA porous scaffold could improve the surface hydrophobicity, reduce the acidic environment of the degradation, and enhance the osteoinductivity; moreover, the ability of protein adsorption and the modulus of compression were increased. The results also clearly showed the effectiveness of the Sr-HA/PLLA porous scaffold in promoting cell adhesion, proliferation, and alkaline phosphatase (ALP) activity. The micro computed tomography (micro-CT) results showed that more new bones were formed by Sr HA/PLLA porous scaffold treatment. The histological results confirmed the osteoinductivity of the Sr-HA/PLLA porous scaffold. The results suggested that the Sr-HA/PLLA porous scaffold has a good application prospect in bone tissue engineering in the future. Purpose: The purpose of this study was to promote the bone repair. Materials and methods: Surgical operation of rabbits was carried out in this study. Results: The results showed that formation of a large number of new bones by the Sr-HA/PLLA porous scaffold treatment is possible. Conclusion: Biomimetic mineralized Sr-HA/PLLA porous scaffold could effectively promote the restoration of bone defects in vivo. PMID- 29599618 TI - A Survey of Epilepsy-related Knowledge, Attitudes and Practices of Home Healthcare Nurses in the San-in Region of Japan. AB - Background: Comprehensive care is necessary for people with epilepsy (PWE) to lead a fulfilling life at home and in the community. The purpose of this study was to determine the epilepsy-related knowledge, attitudes and practices of home healthcare nurses (HHNs) in the San-in region of Japan. Methods: A questionnaire survey was conducted by mail of 546 HHNs working in Tottori and Shimane Prefectures. The questionnaire assessed the epilepsy-related knowledge, attitudes and practices of HHNs. For the analysis, simple and cross tabulation of questionnaire responses were conducted, and the chi-squared test was used for statistical testing. Results: A total of 285 HHNs participated in the study. Of the respondents, 43.9% had experience taking care of PWE in a home healthcare nursing setting. Regarding the cause of epilepsy, in descending order the percentage of correct responses were 86.7% for stroke, 85.3% for head injury, and only 13.3% for dementia. Concerning how to respond to an epileptic seizure, almost all respondents answered correctly, but 29.8% gave the incorrect answer of "place something inside the mouth." Regarding the practices of HHNs in relation to caring for PWE, nurses scored 52.0% for collaborating with the attending physician, indicating the need for improvement. The score for "provide information about social resources" was low at 18.4%. Of the respondents, 95.8% answered that epilepsy-related knowledge and technical skills were necessary for home healthcare nursing practice, and 87.7% were interested in participating in a workshop on epilepsy. Conclusion: The study revealed an inadequate level of knowledge of epilepsy with dementia and corresponding epileptic seizures, a low awareness of nursing care in collaboration with physicians, and the importance of providing information about social resources. There is a need to offer information and education on the latest knowledge about epilepsy to HHNs. PMID- 29599617 TI - Resolvin E1 Inhibits Osteoclastogenesis and Bone Resorption by Suppressing IL-17 induced RANKL Expression in Osteoblasts and RANKL-induced Osteoclast Differentiation. AB - Background: Resolvin E1 (RvE1) derived from the omega-3 polyunsaturated fatty acid eicosapentaenoic acid is known to be a potent pro-resolving lipid mediator that prevents chronic inflammation and osteoclastogenesis. We investigated the inhibitory effects of RvE1 on osteoclastogenesis and bone resorption to clarify its therapeutic potential for rheumatoid arthritis (RA). Methods: Receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclast differentiation was assessed with tartrate-resistant acid phosphatase staining. RANKL-induced bone resorption was assessed by the measurement of pit formation using calcium phosphate-labeled fluorescent polyanionic molecules in RAW264.7 cells as osteoclast precursors. The effects of RvE1 on the RANKL-induced mRNA expression of osteoclast-specific genes and transcriptional factors such as c-fos and nuclear factor of activated T cells c1 (NFATc1) in RAW264.7 cells were measured by quantitative real-time PCR. The distribution of NFATc1 induced by RANKL was evaluated by immunofluorescence staining in RAW264.7 cells. To analyze the mechanism of the inhibitory effect of RvE1 on osteoclastogenesis, we measured IL-17-induced RANKL mRNA expression in MC3T3-E1 osteoblast cells treated with RvE1 using quantitative real-time PCR and determined the level of prostaglandin E2 (PGE2) production by enzyme-linked immunosorbent assay. Results: RvE1 significantly suppressed RANKL-induced osteoclast differentiation and bone resorption. RvE1 inhibited the RANKL-induced mRNA expression of osteoclast specific genes along with the transcription factors NFATc1 and c-fos. Moreover, NFATc1 translocation from the cytoplasm to the nucleus of RAW264.7 cells was suppressed following RvE1 treatment. RvE1 also inhibited IL-17-induced RANKL mRNA expression and PGE2 production in MC3T3-E1 cells. Conclusion: RvE1 inhibited osteoclastogenesis and bone resorption by suppressing RANKL-induced NFATc1 and c fos expression in osteoclasts and IL-17-induced RANKL expression through the autocrine action of PGE2 in osteoblasts. Our data suggest RvE1 as a new therapeutic target of RA. PMID- 29599619 TI - Association of Clinical Features with Human Leukocyte Antigen in Japanese Patients with Ulcerative Colitis. AB - Background: The human leukocyte antigen (HLA) region has been found to be involved in the pathogenesis of inflammatory bowel disease (IBD), which is classified into ulcerative colitis (UC) and Crohn's disease (CD), by genome-wide association studies. The aim of this study was to confirm whether HLA-alleles confer susceptibility to UC and to determine whether HLA-allel1es are associated with the clinical phenotypes in Japanese patients with UC. Methods: In this study, HLA typing was performed by PCR-sequence-specific oligonucleotides (PCR SSO) to confirm the correlation between UC and HLA alleles (for HLA-A, B, DRB1) in 45 Japanese UC patients. In addition, whether the HLA alleles are related to patient and clinical background characteristics was examined. Results: Overall, 62.2%, and 66.7% of the 45 UC patients had HLA-B*52 and HLA-DRB1*15, respectively. These allele frequencies were significantly higher than in previously reported Japanese control persons (P < 0.0001). The frequencies of extraintestinal manifestations [odds ratio (OR) = 0.12, P = 0.039] and a history of colectomy (OR = 0.18, P = 0.046) were lower in HLA-B*52-positive UC patients than in HLA-B*52 negative UC patients. The white blood cell (WBC) count was significantly higher in HLA-DRB1*15-positive patients (9430 +/- 4592/MUL) than in HLA-DRB1*15-negative patients (6729 +/- 2160/MUL). Thus, HLA-B*52 and DRB1*15 appear to be associated with disease features and severity in Japanese UC patients. Conclusion: These results indicate that HLA-B*52 and DRB1*15 are not only associated with overall UC susceptibility, but also with the clinical phenotypes in Japanese patients. PMID- 29599620 TI - Vanishing Parotid Tumors on MR Imaging. AB - Background: Of all parotid gland tumors, only oncocytoma has been reported to appear isointense to the parotid gland, namely vanishing, on fat-saturated T2 and T1 postcontrast gadolinium-enhanced magnetic resonance imaging (MRI). The purpose of this study was to evaluate vanishing of parotid tumors on conventional MRI with and/or without postcontrast gadolinium-enhancement and on diffusion weighted imaging (DWI). Methods: In 8 of 51 patients, ten parotid gland tumors had homogeneously enhanced lesions and were retrospectively analysed. Comparisons of signal intensity between those parotid tumors and parotid glands and evaluations of vanishing were performed on T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), fat-suppressed T2WI (FS-T2WI), postcontrast gadolinium-enhanced T1WI (CE T1WI) and fat-suppressed CE-T1WI (FS-CE-T1WI), DWI as well as apparent diffusion coefficient (ADC). Results: Ten parotid gland tumors consisted of five Warthin tumors, two pleomorphic adenomas, two parotid carcinomas (small cell carcinoma and adenoid cystic carcinoma) and one oncocytoma. All tumors showed hypointensity on T1WI and hyperintensity on DWI. Nine of ten tumors showed vanishing on the other MR sequences. All Warthin tumors showed vanishing on FS-T2WI, FS-CE-T1WI and the ADC map. One oncocytoma showed vanishing on FS-T2WI and the ADC map and hyperintensity on FS-CE-T1WI. All pleomorphic adenomas showed vanishing on T2WI and CE-T1WI. One adenoid cystic carcinoma showed vanishing only on CE-T1WI. Conclusion: Vanishing of parotid tumors can be observed not only on FS-T2WI and FS-CE-T1WI but also on T2WI, CE-T1WI and ADC mapping. PMID- 29599621 TI - Core Values in Nursing Care Based on the Experiences of Nurses Engaged in Neonatal Nursing: A Text-mining Approach for Analyzing Reflection Records. AB - Background: Strong feelings about and enthusiasm for nursing care are reflected in nurses' thoughts and behaviors in clinical practice and affect their profession. This study was conducted to identify the characteristics of core values in nursing care based on the experiences of nurses engaged in neonatal nursing through a process for recognizing the conceptualization of nursing. Methods: We conceptualized nursing care in 43 nurses who were involved in neonatal nursing using a reflection sheet. We classified descriptions on a sheet based on the Three-Staged Recognition scheme and analyzed them using a text mining approach. Results: Nurses involved in neonatal nursing recognized that they must take care of the "child," "mother," and "family." Important elements of nursing in nurses with less than 5 years versus 5 or more years of neonatal nursing experience were classified into seven clusters, respectively. These elements were mainly related to family members in both groups. In nurses with less than 5 years of experience, four clusters of one-way communication by nurses were observed in the analysis of the key elements in nursing. On the other hand, five clusters of mutual relationships between patients, their family members, and nurses were observed in nurses with 5 or more years of experience. Conclusion: In conclusion, the core value of nurses engaged in neonatal nursing is family oriented nursing. Nurses with 5 or more years of neonatal nursing experience understand patients and their family members well through establishing relationships and providing comfort and safety while taking care of them. PMID- 29599622 TI - Sample Entropy in Electrocardiogram During Atrial Fibrillation. AB - Background: Atrial fibrillation (AF) is an arrhythmia commonly encountered in clinical practice. There is a high risk of thromboembolism in patients with AF. Nonlinear analyses such as electroencephalogram (EEG), electrocardiogram (ECG), and respiratory movement have been used to quantify biological signals, and sample entropy (SampEn) has been employed as a statistical measure to evaluate complex systems. In this study, we examined the values of SampEn in ECG signals for patients with and without AF to measure the regularity and complexity. Methods: ECG signals of lead II were recorded from 34 subjects without arrhythmia and 15 patients with chronic AF in a supine position. The ECG signals were converted into time-series data and SampEn was calculated. Results: The SampEn values for the group without arrhythmia were 0.252 +/- 0.114 [time lag (tau) = 1] and 0.533 +/- 0.163 (tau = 5), and those for the chronic AF group were 0.392 +/- 0.158 (tau = 1) and 0.759 +/- 0.246 (tau = 5). The values of SampEn were significantly higher in the group with chronic AF than in the group without arrhythmia (P < 0.01 for tau = 1, P < 0.004 for tau = 5). The constructed three dimensional vectors were plotted in time-delayed three-dimensional space. We used time lags of tau = 5 and tau = 1. The shape of the loops of the three-dimensional space was better for tau = 5. Conclusion: The values of SampEn from ECG for chronic AF patients were higher than for subjects without arrhythmia, suggesting greater complexity for the time-series from chronic AF patients. SampEn is considered a new index for evaluating complex systems in ECG. PMID- 29599623 TI - Comparison of Prognostic Indices in Japanese Patients with Diffuse Large B-cell Lymphoma in the Yonago Area. AB - Background: Several prognostic indices for diffuse large B-cell lymphoma (DLBCL) have been developed. Which index is appropriate for Japanese patients with DLBCL treated in real-world practice is unknown. Methods: The prognostic performances of the original international prognostic index (IPI), age-adjusted IPI, National Comprehensive Cancer Network-IPI, elderly IPI and revised IPI were compared using patients with DLBCL treated in a single institute in the Yonago area in Japan. Results: From 2005 through 2015, 182 patients with de novo DLBCL were treated with chemotherapy in Tottori University Hospital; 154 (85%) patients received R CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) although full dose was administered in 63 (35%) patients. The median age of the patients was 71 years (range 18 to 91). Three-year overall survival rate was 71.8% (95% CI, 64.1% to 78.2%). All indices significantly discriminate risk groups for overall survival of the patients (P < 0.001). Although no statistical difference of performance was found among these indices, the best scores of model fit/discrimination measures were beaten out by age-adjusted IPI, the simplest and three-factor model. Conclusion: Age-adjusted IPI is still usable in real-world practice while a better predictive model is desired for Japanese patients with DLBCL. PMID- 29599624 TI - Histological Evaluation of Lumbar Spine Changes in Rats with Collagen-induced Arthritis. AB - Background: To histologically evaluate lumbar involvement in rheumatoid arthritis (RA) by investigating rats with collagen-induced arthritis (CIA) and to assess the potential effects of RA on the discovertebral joints and facet joints. Methods: Seven-month-old female Sprague-Dawley rats were divided into groups with CIA and without CIA (control). All rats were sacrificed at 8 weeks after initial sensitization and the lumbar spine (L5/6) was harvested. Then the lumbar spine block specimens were stained with Villaneuva bone stain and sectioned in the midsagittal plane. The left facet joints were also sectioned in the midaxial plane. Specimens were studied under a microscope and infiltration of inflammatory cells was investigated. Results: In the CIA group, lumbar lesions were observed in 13/18 rats (76%). Lymphocytes infiltrated into the anterior rim of the vertebral bodies only in 2 rats, while lymphocytes infiltrated the facet joints only in 4 rats. Both sites were involved in 7 rats. In addition, osteoclasts invaded the anterior rim of the vertebral bodies and formed cavities that also contained lymphocytes. Formation of pannus was seen in the facet joints in 11/18 rats. Conclusion: In CIA rats, infiltration of inflammatory cells into the anterior rim of the vertebral bodies alone or into the facet joints alone was demonstrated in 2 rats and 4 rats, respectively, while both sites were involved in 7 rats. Therefore, lesions at the anterior rim of the vertebral body did not arise secondary to facet joint involvement, but were caused by CIA along with synovial lesions of the facet joints. PMID- 29599625 TI - Postoperative Serum Albumin is a Potential Prognostic Factor for Older Patients with Gastric Cancer. AB - Background: The incidence of gastric cancer (GC) among older adults is increasing. Therefore, determining postoperative age-associated prognostic factors is clinically important. This study retrospectively investigated the prognostic significance of serum albumin level in older GC patients. Methods: We enrolled 135 patients aged >= 75 years, who underwent gastrectomies with histopathological diagnoses of gastric adenocarcinoma. Results: Preoperative albumin (pre-Alb) levels in patients with advanced GC and stage III/IV GC were significantly lower than those in patients with early GC (P = 0.0032) and stage I/II GC (P = 0.006), respectively. Postoperative albumin (post-Alb) levels (measured 1 month after surgery) in male patients and in patients with advanced GC were significantly lower than those in female patients (P = 0.024) and those with early GC (P = 0.044), respectively. Post-Alb levels of patients who died of other diseases were significantly lower than those who were still living (P = 0.0004). Prognosis of patients with high post-Alb levels (>= 4g/dL) was significantly better than that of patients with low post-Alb levels (< 4g/dL; P = 0.045); and in multivariate analysis, post-Alb level was an independent prognostic indicator. Conclusion: Post-Alb level is a useful predictive factor for the prognosis of older GC patients. Postoperative nutritional support might help improve the prognosis of older GC patients. PMID- 29599626 TI - Benign Sebaceous Epithelioma with Carcinoid-like Trabecular Cell Arrangement. AB - A case of 75-year-old woman with sebaceous epithelioma was reported. The histological features were distinct in that it had a sinusoidal and carcinoid like growth pattern, which has been reported in its malignant counterpart. Immunostaining for adipophilin was positive in the area with lipid-laden vacuolated cells, but the rest of tumor, which had cord-like nests, was negative. MIB index was 2%. CK5/6 and p40 were positive in the cord-like nesting areas. CK7, CK20, alpha SMA, and epithelial membrane antigen were negative in both the cord-like nesting areas and the adipose-like areas. The tumor was diagnosed as sebaceous epithelioma with a trabecular pattern. Dermatopathologists should be aware of this atypical histological pattern of benign sebaceous epithelioma. PMID- 29599627 TI - Small Bowel Obstruction Due to Mochi (Rice Cake): A Case Report and Review of the Literature. AB - A 66-year-old man presented at our emergency department with severe intermittent abdominal pain. His history revealed that he had eaten several mochi (rice cakes) without sufficiently chewing them before swallowing. Following computed tomography that showed a high value, he was diagnosed with an obstruction caused by mochi. Although mochi obstruction can sometimes improve with conservative treatment, this case required laparotomy. Medical literature in English on small bowel obstruction due to mochi is rare, but fortunately in this case we were able to collect complete laboratory and imaging data. Furthermore, due to the surgical findings, we could clearly diagnose the pathophysiology of mochi obstruction. Here we describe a case of small bowel obstruction due to mochi, and review the literature to determine the characteristics of intestinal obstruction caused by it. PMID- 29599628 TI - Analysis of Acute Transfusion Reactions and Their Occurrence Times. AB - Acute transfusion reactions (ATRs) are significantly relevant to the morbidity and mortality of patients. ATRs are mostly not severe and rarely cause severe conditions, including anaphylactic shock. The aim of this study was to clarify the frequency of ATRs and the time of event occurrence. A total of 18,745 transfusions were administered to 11,718 patients during a 3-year period. Adverse reactions including at least one sign or symptom were collected through a report system in 143 of 2,478 (5.7%) platelet concentrate transfusions, 105 of 6,629 (1.6%) red blood cell component transfusions and 51 of 2,307 (2.2%) fresh frozen plasma transfusions. Allergic signs and symptoms accounted for 70% of all adverse events. Severe signs and symptoms were observed in 7.1% of patients. These events appeared significantly earlier than those of non-severe signs and symptoms (median time 20 min vs 100 min, P < 0.05). For patients who have had repetitive transfusion-associated adverse events, preventive treatments for adverse events should be proactively promoted. PMID- 29599629 TI - The First Awake Clipping of a Brain Aneurysm in Malaysia and in ASEAN: Achieving International Standards. AB - World-renowned neurosurgeon, Professor Saleem Abdulrauf, has been featured in several medical journals for his successful "Awake Brain Aneurysm Surgery". Regarded as a "world first", this surgery, involves clipping un-ruptured brain aneurysms while patients are awake. Only one or two neurosurgery centres worldwide are capable of this. Performing the surgery while the patient is awake lowers risks of brain ischemia with neurological deficits and ventilator associated morbidities. The technique has been viewed as the start of a new era in brain surgery. Physicians from the Universiti Sains Malaysia (USM) School of Medical Sciences, at the Health Campus in Kelantan, headed by Professor Dr Zamzuri Idris (neurosurgeon) and Dr Wan Mohd Nazaruddin Wan Hassan (neuroanaesthetist), recently performed a similar procedure, the first such surgery in Malaysia and Southeast Asia. The USM team can therefore be considered to be among the first few to have done this brain surgery and achieved successful patient outcomes. PMID- 29599630 TI - Potential Benefits of Annona muricata in Combating Cancer: A Review. AB - The incidence of cancer is increasing each year, which generates concerns regarding the efficacy of the current treatment options. This has caused patients to seek alternatives to complement or to replace surgery, chemotherapy and radiotherapy. Annona muricata and other plants have been shown to have promising compounds that can be utilised in the treatment of cancer. Native to the tropical and subtropical parts of the world, A. muricata plant extracts contain compounds that are particularly effective against cancer cells. In light of increasing concerns regarding the limitations of cancer treatment in hospitals, this review attempts to highlight the benefits of A. muricata and its potential to be integrated as one of the treatment options against cancer. PMID- 29599631 TI - The Effect of Amygdalin on Endoplasmic Reticulum (ER) Stress Induced Hepatic Steatosis in Mice. AB - Background: Endoplasmic reticulum (ER) stress creates abnormalities in the insulin action, inflammatory responses, lipoprotein B100 degradation, and hepatic lipogenesis. Hepatic steatosis leads to a broad spectrum of hepatic disorders such as nonalcoholic fatty liver disease (NAFLD) and NASH. Amygdalin has beneficial effects on asthma, bronchitis, diabetes, and atherosclerosis. We designed this study to evaluate the effect of amygdalin on the ER stress induced hepatic steatosis. Methods: Inbred mice received saline, DMSO and amygdalin, as control groups. ER stress was induced by tunicamycin (TM) injection. Amygdalin was administered 1 h before the TM challenge (Amy + TM group). Mice body and liver weights were measured. Hematoxylin and eosin (H&E) and oil red O staining from liver tissue, were performed. Alanin aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride and cholesterol levels were measured. Results: Histological evaluation revealed that amygdalin was unable to decrease the TM induced liver steatosis; however, ALT and AST levels decreased [ALT: 35.33(2.15) U/L versus 92.33(6.66) U/L; (57.000, (50.63, 63.36), P < 0.001) and AST: 93(5.09) U/L versus 345(97.3) U/L, (252, (163.37, 340.62), P < 0.001)]. Amygdalin also decreased triglyceride and cholesterol plasma levels in the Amy + TM group [TG: 42.66(2.15) versus 53.33(7.24) mg/dL; (10.67, (3.80, 17.54), P = 0.006) and TC: 9.33(3.55) versus 112.66(4.31) mg/dL, (103.33, (98.25, 108.40) P < 0.001)]. Conclusion: Amygdalin improved the ALT, AST, and lipid serum levels after the TM challenge; however, it could not attenuate hepatic steatosis. PMID- 29599632 TI - Comparison of the Effects of Dexmedetomidine on the Induction of Anaesthesia Using Marsh and Schnider Pharmacokinetic Models of Propofol Target-Controlled Infusion. AB - Background: The study aimed to determine the effects of dexmedetomidine on the induction of anaesthesia using different models (Marsh and Schnider) of propofol target-controlled infusion (TCI). Methods: Sixty-four patients aged 18-60 years, American Society of Anaesthesiologists (ASA) class I-II who underwent elective surgery were randomised to a Marsh group (n = 32) or Schnider group (n = 32). All the patients received a 1 MUg/kg loading dose of dexmedetomidine, followed by TCI anaesthesia with remifentanil at 2 ng/mL. After the effect-site concentration (Ce) of remifentanil reached 2 ng/mL, propofol TCI induction was started. Anaesthesia induction commenced in the Marsh group at a target plasma concentration (Cpt) of 2 MUg/mL, whereas it started in the Schnider group at a target effect-site concentration (Cet) of 2 MUg/mL. If induction was delayed after 3 min, the target concentration (Ct) was gradually increased to 0.5 MUg/mL every 30 sec until successful induction. The Ct at successful induction, induction time, Ce at successful induction and haemodynamic parameters were recorded. Results: The Ct for successful induction in the Schnider group was significantly lower than in the Marsh group (3.48 [0.90] versus 4.02 [0.67] MUg/mL; P = 0.01). The induction time was also shorter in the Schnider group as compared with the Marsh group (134.96 [50.91] versus 161.59 [39.64]) sec; P = 0.02). There were no significant differences in haemodynamic parameters and Ce at successful induction. Conclusion: In the between-group comparison, dexmedetomidine reduced the Ct requirement for induction and shortened the induction time in the Schnider group. The inclusion of baseline groups without dexmedetomidine in a four-arm comparison of the two models would enhance the validity of the findings. PMID- 29599633 TI - The Factors Associated with Outcomes in Surgically Managed Ruptured Cerebral Aneurysm. AB - Background: Ruptured cerebral aneurysm is a life-threatening condition that requires urgent medical attention. In Malaysia, a prospective study by the Umum Sarawak Hospital, Neurosurgical Center, in the year 2000-2002 revealed an average of two cases of intracranial aneurysms per month with an operative mortality of 20% and management mortality of 25%. Failure to diagnose, delay in admission to a neurosurgical centre, and lack of facilities could have led to the poor surgical outcome in these patients. The purpose of this study is to identify the factors that significantly predict the outcome of patients undergoing a surgical clipping of ruptured aneurysm in the local population. Material and Method: A single center retrospective study with a review of medical records was performed involving 105 patients, who were surgically treated for ruptured intracranial aneurysms in the Sultanah Aminah Hospital, in Johor Bahru, from July 2011 to January 2016. Information collected was the patient demographic data, Glasgow Coma Scale (GCS) prior to surgery, World Federation of Neurosurgical Societies Scale (WFNS), subarachnoid hemorrhage (SAH) grading system, and timing between SAH ictus and surgery. A good clinical grade was defined as WFNS grade I-III, whereas, WFNS grades IV and V were considered to be poor grades. The outcomes at discharge and six months post surgery were assessed using the modified Rankin's Scale (mRS). The mRS scores of 0 to 2 were grouped into the "favourable" category and mRS scores of 3 to 6 were grouped into the "unfavourable" category. Only cases of proven ruptured aneurysmal SAH involving anterior circulation that underwent surgical clipping were included in the study. The data collected was analysed using the Statistical Package for Social Sciences (SPSS). Univariate and multivariate analyses were performed and a P-value of < 0.05 was considered to be statistically significant. Result: A total of 105 patients were included. The group was comprised of 42.9% male and 57.1% female patients. The mean GCS of the patients subjected to surgical clipping was 13, with the majority falling into the good clinical grade (78.1%). The mean timing of the surgery after SAH was 5.3 days and this was further categorised into early (day one to day three, 45.3%), intermediate (day four to day ten, 56.2%), and late (after day ten, 9.5%). The total favourable outcome achieved at discharge was 59.0% as compared to 41.0% of the unfavourable outcome, with an overall mortality rate of 10.5%. At the six month post surgery review (n = 94), the patients with a favourable outcome constituted 71.3% as compared to 28.7% with an unfavourable outcome. The mortality, six months post surgery was 3.2%. On a univariate analysis of early surgical clipping, patients with a better GCS and good clinical grade had a significantly better outcome at discharge. Based on the univariate study, six months post surgery, the timing of the surgery and the clinical grade remained significant predictors of the outcome. On the basis of the multivariate analysis, male patients of younger age, with a good clinical grade, were associated with favourable outcomes, both at discharge and six months post surgery. Conclusion: In this study, we concluded that younger male patients with a good clinical grade were associated with a favourable outcome both at discharge and six months post surgery. We did not find the timing of the surgery, size of the aneurysm or duration of surgery to be associated with a patient's surgical outcome. Increasing age was not associated with the surgical outcome in a longer term of patient's follow up. PMID- 29599634 TI - Association of Co-Morbidity and Treatment with the Complications of Acute Coronary Syndrome in Young Patients Less Than 45 Years. AB - Background: Approximately 5%-10% of acute coronary syndrome (ACS) cases occur in people younger than 45 years of age. This study aimed to identify complications of ACS and the associated factors in young patients. Methods: In this cross sectional study, data from 147 ACS patients aged less than 45 years were analysed. Results: The mean age was 39.1 (4.9) years, the male to female ratio was 3:1; 21.2% of patients presented with unstable angina, 58.5% had non-ST elevation myocardial infarction and 20.4% had ST elevation myocardial infarction. The most frequent risk factor of ACS was dyslipidaemia (65.3%), followed by hypertension (43.5%). In total, 49.7% of patients had inpatient complication(s), with the most common being heart failure (35.4%), followed by arrhythmia (20.4%). The significant factors associated with ACS complications were current smoking [adjusted odds ratio (AOR) 4.03; 95% confidence interval (CI): 1.33, 12.23; P value = 0.014], diabetic mellitus [AOR 3.03; 95% CI: 1.19, 7.71; P-value = 0.020], treatments of fondaparinux [AOR 0.18; 95% CI: 0.08, 0.39; P-value < 0.001] and oral nitrates [AOR 0.18; 95% CI: 0.08, 0.42; P-value < 0.001]. Conclusions: Smoking status and diabetes mellitus were modifiable risk factors while pharmacological treatment was an important protective factor for ACS complications in young patients. PMID- 29599635 TI - The Effectiveness of Breastfeeding Intervention on Breastfeeding Exclusivity and Duration among Primiparous Mothers in Hospital Universiti Sains Malaysia. AB - Background: In Malaysia, the rates of mothers practising breastfeeding exclusively among babies at six months of age still do not achieve the Global Nutritional Targets 2025 which is 50%. Objective: To determine the effectiveness of breastfeeding intervention in improving breastfeeding outcomes. Method: A quasi-experimental design was used involving a purposive sample of 96 primigravidas (intervention group (IG) = 48, control group (CG) = 48) recruited at Hospital USM. Data were collected using the Breastfeeding Assessment Questionnaire. Mothers in IG received the current usual care and two hours of an additional education programme on breastfeeding, breastfeeding booklet, notes from the module, and postnatal breastfeeding support in the first week of postpartum. Mothers in CG received the current usual care only. The mothers were assessed on the first and sixth week and then the fourth and sixth month of postpartum. Results: The results indicated that there was a statistically significant difference between the groups on the fourth month postpartum (X2 = 5.671, P = 0.017) in practicing full breastfeeding. The breastfeeding duration rates of the IG were longer than those of the CG. However, the results showed only two follow-up weeks that were significant (week 6, X2 = 5.414, P = 0.020, month 4, X2 = 7.515, P = 0.006). There was a statistically significant difference between IG and CG as determined by one-way ANCOVA on the breastfeeding duration after controlling age and occupation, F (3, 82) = 6.7, P = 0.011. The test revealed that the breastfeeding duration among IG was significantly higher (20.80 +/- 6.31) compared to CG (16.98 +/- 8.97). Conclusions: Breastfeeding intervention can effectively increase breastfeeding duration and exclusivity outcomes among primiparous mothers. PMID- 29599636 TI - The Influence of Audio-Visual Cueing (Traffic Light) on Dual Task Walking in Healthy Older Adults and Older Adults with Balance Impairments. AB - Background: The walking gait of older adults with balance impairment is affected by dual tasking. Several studies have shown that external cues can stimulate improvement in older adults' performance. There is, however, no current evidence to support the usefulness of external cues, such as audio-visual cueing, in dual task walking in older adults. Thus, the aim of this study was to investigate the influence of an audio-visual cue (simulated traffic light) on dual task walking in healthy older adults and in older adults with balance impairments. Methods: A two-way repeated measures study was conducted on 14 healthy older adults and 14 older adults with balance impairment, who were recruited from the community in Chiang Rai, Thailand. Their walking performance was assessed using a four-metre walking test at their preferred gait speed and while walking under two further gait conditions, in randomised order: dual task walking and dual task walking with a simulated traffic light. Each participant was tested individually, with the testing taking between 15 and 20 minutes to perform, including two-minute rest periods between walking conditions. Two Kinect cameras recorded the spatio temporal parameters using MFU gait analysis software. Each participant was tested for each condition twice. The mean parameters for each condition were analysed using a two-way repeated measures analysis of variance (ANOVA) with participant group and gait condition as factors. Result: There was no significant between group effect for walking speed, stride length and cadence. There were also no significant effects between gait condition and stride length or cadence. However, the effect between gait condition and walking speed was found to be significant [F(1.557, 40.485) = 4.568, P = 0.024, [Formula: see text]]. Conclusion: An audio visual cue (simulated traffic light) was found to influence walking speed in both healthy older adults and in older adults with balance impairment. The results suggest that audio-visual cues could be incorporated into healthy lifestyle promotion in older adults with balance impairment. PMID- 29599637 TI - Undergraduate Medical Students' Perceptions on Feedback-Seeking Behaviour. AB - Background: The concept of feedback-seeking behaviour has been widely studied, but there is still a lack of understanding of this phenomenon, specifically in an Indonesian medical education setting. The aim of this research was to investigate medical students' feedback-seeking behaviour in depth in one Indonesian medical school. Methods: A qualitative method was employed to explore the feedback seeking behaviour of undergraduate medical students in the Faculty of Medicine at Universitas Lampung. Focus group discussions (FGDs) were conducted with four student groups and each group consisted of 7-10 students from the years 2012, 2013 and 2014. Data triangulation was carried out through FGDs with teaching staff, and an interview with the Head of the Medical Education Unit. Results: Study findings indicated that the motivation of students to seek feedback was underlain by the desire to obtain useful information and to control the impressions of others. Students will tend to seek feedback from someone to whom they have either a close relationship or whose credibility they value. The most common obstacle for students to seek feedback is the reluctance and fearfulness of receiving negative comments. Conclusions: Through the identification of factors promoting and inhibiting feedback-seeking behaviour, medical education institutions are enabled to implement the appropriate and necessary measures to create a supportive feedback atmosphere in the learning process. PMID- 29599638 TI - Clinical and Sociodemographic Predictors of the Quality of Life among Patients with Type 2 Diabetes Mellitus on the East Coast of Peninsular Malaysia. AB - Background: The quality of life (QoL) describes the multidimensional self perceived well-being of a person, which is an important diabetes outcome. This study aimed to measure the QoL scores among patients with type 2 diabetes mellitus (T2DM), as well as their clinical and sociodemographic predictors. Methods: This cross-sectional study involved 180 randomly sampled patients at a primary care clinic on the East Coast of Peninsular Malaysia. A self-administered questionnaire containing the Audit of Diabetes Dependent Quality of Life-18 (ADDQoL-18) was used. Results: Most of the respondents (96.7%) were Malay, with a median (interquartile range, IQR) age of 54.0 (14.0) years old. The majority of them were females (60.0%), married (81.1%) and from low-income families (63.3%), who attained a secondary education or lower (75.6%). Only 49.4% of them were employed. The mean (standard deviation, SD) ADDQoL-18 average weighted impact score was -4.58 (2.21) and all 18 domains were negatively affected, particularly the living condition, family life and working life. The multiple linear regression analysis showed that the age (adjusted B = 0.05, P = 0.004) and insulin use (adjusted B = -0.84, P = 0.011) were QoL predictors. Conclusion: T2DM negatively impacts the patient's QoL in all aspects of their life. The QoL improvement with age suggests that the older patients had accepted and adapted to their illness. The need to improve the QoL among insulin users was also highlighted. PMID- 29599639 TI - Association of Well-Being Index and Cognitive Impairment with Primary Open Angle Glaucoma Patients of Malaysia: A Case-Control Study. AB - The purpose of this study was to determine the association of well-being and cognitive impairment with primary open angle glaucoma (POAG) patients attending a tertiary care hospital in Malaysia. Fifty-four individuals were recruited for study as cases were matched with 60 individuals as the control subjects, and data were collected using the WHO well-being index and the validated 6-item cognitive impairment test dementia test. The results showed that there was no significant association between gender, ethnicity, socioeconomic status and POAG. Patients with POAG had significantly lower well-being index scores (mean 67.93) than the control group (mean 81.60) with P-value < 0.001. Similarly, patients with POAG had a significantly higher score of cognitive impairment (CIT test) (mean 6.15) compared to the control group (mean 0.40) with P-value < 0.001. Consequently, POAG is likely to be associated with higher cognitive impairment and lower well being index. PMID- 29599641 TI - Large Solitary Pulmonary Cryptococcoma Mimicking Lung Carcinoma in an Immunocompetent Patient. AB - Cryptococcosis is a life-threatening mycosis typically seen in immunocompromised patients. Pulmonary cryptococcosis generally presents as multiple or solitary nodular opacities. Cryptococcal infection presenting as a destructing cavernoma (cryptococcoma) without diffuse infiltration of the lung is an extremely rare presentation, even in immunocompromised patients. This report presents a healthy, HIV negative, immunocompetent patient who presented with a large solitary lung mass provisionally diagnosed as a lung malignancy on radiological imaging that proved to be a large cryptococcoma after biopsy. The patient was treated with liposomal Amphotericin B and fluconazole, and the lesion showed regression on serial imaging. This case report thus highlights an unconventional presentation of pulmonary cryptococcosis in an immunocompetent individual.

PMID- 29599640 TI - The Effects of 4-Hydroxybenzoic Acid Identified from Bamboo (Dendrocalamus asper) Shoots on Kv1.4 Channel. AB - Background: Bamboo shoot has been used as a treatment for epilepsy in traditional Chinese medicine for generations to treat neuronal disorders such as convulsive, dizziness and headaches. 4-hydroxybenzoic acid (4-hba) is a non-flavonoid phenol found abundantly in Dendrocalamus asper shoots (bamboo), fruits (strawberries and apples) and flowers. Kv1.4 is a rapidly inactivating Shaker-related member of the voltage-gated potassium channels with two inactivation mechanisms; the fast N type and slow C-type. It plays vital roles in repolarisation, hyperpolarisation and signaling the restoration of resting membrane potential through the regulation of the movement of K+ across the cellular membrane. Methods: Chemical compounds from Dendrocalamus asper bamboo shoots were purified and identified as major palmitic acids mixed with other minor fatty acids, palmitic acid, 4 hydroxybenzaldehyde, lauric acid, 4-hydroxybenzoic acid and cholest-4-ene-3-one. The response of synthetic 4-hydroxybenzoic acid was tested on Kv1.4 potassium channel which was injected into viable oocytes that was extracted from Xenopus laevis. The current were detected by the two-microelectrode voltage clamp, holding potential starting from -80 mV with 20 mV step-up until +80 mV. Readings of treatments with 0.1% DMSO, 4-hba concentrations and K channel blockers were taken at +60 mV. The ratio of tail/peak amplitude is the index of the activity of the Kv1.4 channels with n >= 6 (number of oocytes tested). The decreases of the ratios of five different concentrations (1 MUM, 10 MUM, 100 MUM, 1 mM and 2.5 mM) were compared with 0.1% DMSO as the control. Results: All concentration showed statistically significant results with P < 0.05 except for 100 MUM. The normalised current of the 4-hba concentrations were compared with potassium channel blockers (TEA and 4-AP) and all groups showed statistically significant results. This study also showed that time taken for each concentration to affect Kv1.4 does not play any significant roles. Conclusion: 4-hydroxybenzoic acid was found to be able to enhance the inactivation of Kv1.4 by lowering the membrane potential so that the abnormal neuronal firing can be inhibited. With IC50 slightly higher than 10 MUM, increasing concentrations (100 MUM, 1 mM and 2.5 mM) had shown to exhibit toxicity effects. The best concentration from this study is 10 MUM with Hill slope of 0.1799. PMID- 29599643 TI - LAMP Method as One of the Best Candidates for Replacing with PCR Method. PMID- 29599644 TI - Does space-time torsion determine the minimum mass of gravitating particles? AB - We derive upper and lower limits for the mass-radius ratio of spin-fluid spheres in Einstein-Cartan theory, with matter satisfying a linear barotropic equation of state, and in the presence of a cosmological constant. Adopting a spherically symmetric interior geometry, we obtain the generalized continuity and Tolman Oppenheimer-Volkoff equations for a Weyssenhoff spin fluid in hydrostatic equilibrium, expressed in terms of the effective mass, density and pressure, all of which contain additional contributions from the spin. The generalized Buchdahl inequality, which remains valid at any point in the interior, is obtained, and general theoretical limits for the maximum and minimum mass-radius ratios are derived. As an application of our results we obtain gravitational red shift bounds for compact spin-fluid objects, which may (in principle) be used for observational tests of Einstein-Cartan theory in an astrophysical context. We also briefly consider applications of the torsion-induced minimum mass to the spin-generalized strong gravity model for baryons/mesons, and show that the existence of quantum spin imposes a lower bound for spinning particles, which almost exactly reproduces the electron mass. PMID- 29599645 TI - What if gravity becomes really repulsive in the future? AB - The current acceleration of the Universe is one of the most puzzling issues in theoretical physics nowadays. We are far from giving an answer in this letter to the question of its nature. Yet, with the observations we have at hand, we analyse the different patterns that the gravitational potential can show in the future. Surprisingly, gravity not only can get weaker in the near future, it can even become repulsive; or equivalently, the gravitational potential may become negative. We show this remark by using one of the simplest phenomenological model we can imagine for dark energy. We have also reviewed the statefinder approach of these models. For completeness, we have also showed the behaviour of the density contrast of dark matter and dark energy for these simple (yet illustrative models). Our results are displayed and we see how they shall evolve in the future. PMID- 29599646 TI - lncRNAs Regulate Innate Immune Responses and Their Roles in Macrophage Polarization. AB - The innate immune system is the first line of defense against microbial pathogens. The activated innate immune system plays important roles in eliciting antimicrobial defenses. Despite the benefits of innate immune responses, excessive inflammation will cause host damage. Thus, tight regulation of these processes is required for the maintenance of immune homeostasis. Recently, a new class of long noncoding RNAs (lncRNAs) has emerged as important regulators in many physiological and pathological processes. Dysregulated lncRNAs have been found to be associated with excessive or uncontrolled inflammation. In this brief review, we summarize the roles of functional lncRNAs in regulating innate immune responses. We also discuss the roles of lncRNAs in macrophage polarization, an important molecular event in the innate immune responses. PMID- 29599647 TI - Prognostic value of long non-coding RNA BLACAT1 in patients with papillary thyroid carcinoma. AB - Background: Long noncoding RNAs (lncRNAs) have been reported to have potential diagnostic and prognostic values for numerous cancers. However, the plasma expression of lncRNA BLACAT1 and its clinical value in patients with papillary thyroid cancer (PTC) remain unknown. Methods: The expression profile of BLACAT1 in 87 PTC patients (case group) and 36 patients with nodular goiter (control group) were investigated by qRT-PCR. The Kaplan-Meier method was used for RFS curves, and the univariate survival differences were analyzed by the log-rank test. Results: BLACAT1 expression was downregulated in the plasma of case group compared with control group (P = 0.003). We also found that low plasma BLACAT1 expression was correlated with lymph node metastasis (LNM) (P < 0.001). Multivariate analysis showed that BLACAT1 was an independent risk factor for lymph node metastasis and gender (P < 0.05). The area under the ROC curve for BLACAT1 was 0.825 in LNM prediction (P < 0.001). Conclusion: The present study demonstrated that BLACAT1 could act as a possible suppressor gene in PTC and may serve as a potential biomarker for prognosis prediction of PTC. PMID- 29599648 TI - Masculine Discrepancy Stress and Psychosocial Maladjustment: Implications for Behavioral and Mental Health of Adolescent Boys. AB - Gender role discrepancy (GRD), or nonconformity to socially prescribed gender roles, has been linked to a multitude of adverse mental and behavioral health outcomes. Masculine discrepancy stress (MDS), stress about being perceived not to conform to one's gender role, may explain the relationship between GRD and deleterious health outcomes. However, research on MDS has primarily been restricted to adult males. This leaves a critical gap pertaining to the potential effect of MDS on adolescent boys, who may be more malleable and susceptible to the influence and pressures of gender socialization. In the current study, data are drawn from a sample of adolescent male students (N = 592) who completed self report questionnaires. We employed structural equation modeling to test the effects of GRD and MDS on psychosocial maladjustment measured via sexual behavior, substance use, violence, mood disorder symptoms, and hopelessness. In addition, we controlled for critical risk factors including sociodemographic characteristics, adverse childhood experiences, trauma symptoms, and neighborhood disorganization. Findings indicate significant potentiating effects of MDS on maladjustment while there were direct protective effects of GRD. These data suggest that developing prevention strategies that incorporate social norms pertaining to gender socialization may have an impact on multiple behavioral and mental health problems.

PMID- 29599650 TI - No Relation between Psoriasis and Renal Abnormalities: A Case-Control Study. AB - Multiple observational studies have demonstrated that psoriasis is associated with nephropathy; however, the renal involvement in psoriasis remains largely a matter of debate. The current study was designed to investigate if psoriatic patients are at increased risk of renal abnormalities, in absence of any other comorbidities. Forty patients (11 women, 29 men, mean age 44.9 +/- 15.45 years) with moderate to severe chronic plaque type psoriasis who were not under systemic therapy and 40 age- and gender-matched control subjects were enrolled in the study. Patients and controls with history of diabetes, hypertension, and chronic renal disease were excluded. Urinalysis by dipstick and microscopic evaluation and 24 h proteinuria and albuminuria were measured in all patients and controls. Patients with psoriasis and controls were not significantly different with respect to the prevalence of abnormal urinalysis (7.5% versus 5%, P = 1.0), mean 24 h proteinuria (70.40 +/- 24.38 mg/24 h versus 89.40 +/- 26.78 mg/24 h, P = 0.30), and albuminuria (14.15 +/- 8.12 mg/24 h versus 16.62 +/- 8.21 mg/24 h, P = 0.18). The presence of abnormal urinalysis was not more common in patients with psoriasis than in controls. Our study demonstrated that psoriatic patients without any other comorbidities are not at increased risk of kidney disease. PMID- 29599651 TI - Mindfulness-Based Interventions in Psychiatry. AB - Mindfulness meditation has a longstanding history in eastern practices that has received considerable public interest in recent decades. Indeed, the science, practice, and implementation of Mindfulness Based Interventions (MBIs) have dramatically increased in recent years. At its base, mindfulness is a natural human state in which an individual experiences and attends to the present moment. Interventions have been developed to train individuals how to incorporate this practice into daily life. The current article will discuss the concept of mindfulness and describe its implementation in the treatment of psychiatric disorders. We further identify for whom MBIs have been shown to be efficacious and provide an up-to-date summary of how these interventions work. This includes research support for the cognitive, psychological, and neural mechanisms that lead to psychiatric improvements. This review provides a basis for incorporating these interventions into treatment. PMID- 29599652 TI - The Utility of Lumbar Puncture After a Negative Head CT in the Emergency Department Evaluation of Subarachnoid Hemorrhage. AB - Background: American College of Emergency Physicians (ACEP) [1] recommends that patients presenting with acute non-traumatic headache concerning for subarachnoid hemorrhage (SAH) undergo lumbar puncture (LP) when non-contrast head computed tomography (CT) is negative. The diagnostic yield of this approach is unknown. Objective: Evaluate the diagnostic yield, lengths of stay and complication rates of LPs in patients undergoing Emergency Department (ED) evaluation for aneurysmal SAH. Methods: Multi-center, retrospective, hypothesis-blinded, explicit chart review of patients undergoing ED-based lumbar puncture between 2007 and 2012. Charts of neurologically intact patients presenting with headache that had a negative head CT and underwent LP primarily to rule out SAH were reviewed. Trained data abstractors blinded to study hypothesis used standardized data forms with predefined terms for chart abstraction. We re-abstracted and assessed inter rater agreement for 20 percent of charts with a 100 percent inter-rater agreement. Data were descriptive, using 95 percent confidence intervals. Results: 1,282 LPs were performed, and 342 patients met inclusion criteria but only 1 percent were deemed positive for SAH in the chart. No aneurysm or vascular malformation was identified in those with positive LPs for SAH. Complications were in 4 percent and xanthochromia was found in 13 percent. Total length of stay was 7.8 hours (0.95 CI; 7.5 - 8.2). No patient discharged from the ED after a negative workup for SAH was re-admitted for SAH or underwent a neurosurgical procedure during a three-month follow-up period. Conclusions: LP in our cohort of neurologically intact CT-negative ED headache patients did not identify any cases of aneurysmal SAH but was associated with serious complications, a significant false positive rate, and extended ED length of stay. PMID- 29599653 TI - Corneal Innervation and Sensation: The Eye and Beyond. AB - The cornea is one of the most densely innervated and sensitive tissues in the body. In addition to their important sensory functions, corneal nerves induce reflex tear production, blinking, and the release of trophic factors - all of which combined help to maintain the structural and functional integrity of the surface of the eye. Consequently, damage to corneal nerves as a result of disease, surgery, or trauma can lead to diminished corneal sensitivity, epithelial defects, and possible blindness. In this review, we describe commonly used tools that have provided considerable new information on corneal architecture and sensation in healthy and diseased corneas, with special emphasis on changes seen in herpes zoster ophthalmicus, corneal and other therapeutic ocular procedures, antiglaucoma medical therapy, aging, and diabetes. With its potential applications ranging from managing ocular-specific to systemic diseases, the study of corneal innervation has implications for future therapies extending beyond just the eye itself.

AB - Recent advances in genetic tools and optical imaging technology have allowed rodent and Drosophila researchers to explore the relationship between serotonergic modulation and olfactory processing at a mechanistic level previously unfeasible. Here, I review the basic organization of olfactory and serotonergic systems in both rodents and Drosophila and draw comparisons where similarities exist. I discuss circuit level models that explain many of serotonin's effects on olfactory responses in the olfactory system's inputs and outputs. Finally, I discuss models of integration within wide-field centrifugal neurons to emphasize the importance of studying serotonergic neurons directly to build more realistic models of olfactory and modulatory interactions. PMID- 29599655 TI - Dark Matters: Challenges of Nocturnal Communication Between Plants and Animals in Delivery of Pollination Services. AB - The night is a special niche characterized by dim light, lower temperatures, and higher humidity compared to the day. Several animals have made the transition from the day into the night and have acquired unique adaptations to cope with the challenges of performing nocturnal activities. Several plant species have opted to bloom at night, possibly as a response to aridity to prevent excessive water loss through evapotranspiration since flowering is often a water-demanding process, or to protect pollen from heat stress. Nocturnal pollinators have visual adaptations to function under dim light conditions but may also trade off vision against olfaction when they are dependent on nectar-rewarding and scented flowers. Nocturnal pollinators may use CO2 and humidity cues emanating from freshly-opened flowers as indicators of nectar-rich resources. Some endothermic nocturnal insect pollinators are attracted to thermogenic flowers within which they remain to obtain heat as a reward to increase their energy budget. This review focuses on mechanisms that pollinators use to find flowers at night, and the signals that nocturnally blooming flowers may employ to attract pollinators under dim light conditions. It also indicates gaps in our knowledge. While millions of years of evolutionary time have given pollinators and plants solutions to the delivery of pollination services and to the offering of appropriate rewards, this history of successful evolution is being threatened by artificial light at night. Excessive and inappropriate illumination associated with anthropogenic activities has resulted in significant light pollution which serves to undermine life processes governed by dim light. PMID- 29599656 TI - Degenerative Cervical Myelopathy: A Clinical Review. AB - Degenerative Cervical Myelopathy (DCM) is the most common form of spinal cord impairment in adults and results in disability and reduced quality of life. DCM can present with a wide set of clinical and imaging findings, including: 1) pain and reduced range of motion of the neck, and motor and sensory deficits on clinical exam, and 2) cord compression due to static and dynamic injury mechanisms resulting from degenerative changes of the bone, ligaments, and intervertebral discs on MRI. The incidence and prevalence of DCM has been estimated at a minimum of 4.1 and 60.5 per 100,000, respectively, but surgical trends and an aging population suggest these numbers will rise in the future. The diagnosis of DCM is based on clinical examination, with a positive Hoffmann's sign and hand numbness typically appearing in the upper limbs, and gait abnormalities such as difficulty with tandem gait serving as sensitive diagnostic findings. Loss of bladder function may also occur in patients with severe DCM. The degree of neurological impairment can be measured using the modified Japanese Association Scale (mJOA) or Nurick grade. Non-operative management has a limited role in the treatment, while surgical management has been shown to both be safe and effective for halting disease progression and improving neurological function. Predictors of surgical outcome include age and baseline severity, indicating that early recognition of DCM is important for ensuring an optimal surgical outcome. PMID- 29599657 TI - Phototransduction in Retinal Ganglion Cells. AB - The mammalian retina contains a small number of retinal ganglion cells that express melanopsin, a retinal based visual pigment, and generate a depolarizing response to light in the absence of rod and cone driven synaptic input; hence they are referred to as intrinsically photosensitive retinal ganglion cells (ipRGCs). They have been shown to be comprised of a number of sub-types and to provide luminance information that participates primarily in a variety of non imaging forming visual functions. Here I review what is currently known about the cascade of events that couple the photoisomerization of melanopsin to the opening of a non-selective cation channel. While these events conform in a general sense to the prevailing model for invertebrate phototransduction, in which visual pigment signals through a G protein of the Gq class and a phospholipase C cascade to open a TRPC type ion channel, none of the molecular elements in the melanopsin transduction process have been unequivocally identified. This has given rise to the possibility that the underlying mechanism responsible for intrinsic photosensitivity is not same in all ipRGC sub-types and to the recognition that signal transduction in ipRGCs is more complex than originally thought.

PMID- 29599658 TI - Sensory Disruption in Modern Living and the Emergence of Sensory Inequities. AB - Modern lifestyles are disrupting the human senses-primarily sight, sound, and smell. Noise-induced hearing loss has been noted for centuries and increasing over time following the industrial era. From the mid-20th century, the numbers of individuals with myopia (the leading visual impairment) have been increasing globally. Historical evidence for olfactory dysfunction is not known but its etiological links to pollution suggest it increased following industrialization. Clinical interventions for sight and sound loss include preventative and corrective measures but none exist for olfactory dysfunction. Further, olfactory loss is linked to multiple negative health outcomes across physical, mental, and social domains. Due to the global rates of exposure to pollution, olfaction is a global health concern. The environmental injustice inherent in human society (locally and globally) results in inequitable risk for sensory loss by the most vulnerable populations and creates an even deeper gradient in health disparity. Situated within the environmental justice and health disparity literature, this paper introduces the term sensory inequity to describe variation in sensory environments based on socio-economic status (which is often entwined with race and education). A key challenge to risk management is awareness of sensory inequity experienced by vulnerable populations and incorporating that awareness into basic research and policy.

AB - Data citation is of growing concern for owners of curated databases, who wish to give credit to the contributors and curators responsible for portions of the dataset and enable the data retrieved by a query to be later examined. While several databases specify how data should be cited, they leave it to users to manually construct the citations and do not generate them automatically. We report our experiences in automating data citation for an RDF dataset called eagle-i, and discuss how to generalize this to a citation framework that can work across a variety of different types of databases (e.g. relational, XML, and RDF). We also describe how a database administrator would use this framework to automate citation for a particular dataset. PMID- 29599663 TI - Interactive effects of work psychosocial factors on participation in workplace wellness programs. AB - This study explored concurrent effects of six work psychosocial factors on current participation and the self-reported likelihood of future participation in workplace wellness programs using a cross-sectional survey, an ad hoc focus group, and structured interviews. Classification and regression tree analysis was used to analyze survey responses from 343 employees (194 nonparticipants, 95 participants, and 54 engaged participants). A thematic analysis of focus group (n = 7) and interview (n = 5) narratives was also undertaken. In combination with high work control, high superior support was associated with an engaged participant profile. Job demand was the third important variable with low and very high levels associated with participation. With regard to high likelihood of future participation, among respondents with age older than 50, high predictability of occupational activities and control were identified as a significant factor, and among others, high superior support and control. The analysis of narratives revealed peer relations and flexible working hours to be positively linked to participation and general job stress was identified as having a bidirectional relationship. Employees stated that stress led them to take advantage of these programs as a source of relief and that their availability/participation has contributed to lowering their stress. These findings inform practitioners about the importance of addressing poor psychosocial factors as a participation barrier and having a holistic approach to employee well-being.

AB - To assess growing season conditions where ground based observations are limited or unavailable, food security and agricultural drought monitoring analysts rely on publicly available remotely sensed rainfall and vegetation greenness. There are also remotely sensed soil moisture observations from missions like the European Space Agency (ESA) Soil Moisture and Ocean Salinity (SMOS) and NASA's Soil Moisture Active Passive (SMAP), however these time series are still too short to conduct studies that demonstrate the utility of these data for operational applications, or to provide historical context for extreme wet or dry events. To promote the use of remotely sensed soil moisture in agricultural drought and food security monitoring, we use East Africa as a case study to evaluate the quality of a 30+ year time series of merged active-passive microwave soil moisture from the ESA Climate Change Initiative (CCI-SM). Compared to the Normalized Difference Vegetation index (NDVI) and modeled soil moisture products, we found substantial spatial and temporal gaps in the early part of the CCI-SM record, with adequate data coverage beginning in 1992. From this point forward, growing season CCI-SM anomalies were well correlated (R>0.5) with modeled, seasonal soil moisture, and in some regions, NDVI. We use correlation analysis and qualitative comparisons at seasonal time scales to show that remotely sensed soil moisture can add information to a convergence of evidence framework that traditionally relies on rainfall and NDVI in moderately vegetated regions.

AB - Atopic dermatitis is a chronic, recurrent inflammatory skin disease, which is frequently familial. The main cause of the disease seems to be a defect of the epidermal barrier resulting from a genetic predisposition concerning the epidermis, functioning of the immune system as well as environmental factors (which are not related to the immune system). Genes responsible for encoding protein S100, filaggrin, proteases and their inhibitors are the main genes related to the problem of epidermal barrier dysfunction. There is a close connection between structural and immunological processes. Increased expression of cytokine Th2 profile belongs to the latter category. The objective of the present paper is to describe the influence of aforementioned factors on epidermis structure and dysfunction which leads to clinical symptoms of atopic dermatitis. PMID- 29599668 TI - Selected presentations of lip enlargement: clinical manifestation and differentiation. AB - Lip enlargement may be an important symptom of either systemic or local diseases. On the basis of selected age-matched clinical cases we present the possible causes of lip swelling. We describe the most representative symptoms and recommend treatment of these pathologies. We differentiate lip swelling in Miescher syndrome, monosymptomatic form of Melkersson-Rosenthal syndrome, lip swelling in erythema multiforme and Stevens-Johnson syndrome and lip hemangioma and mucous extravasation cyst. We compare different causes of lip edema and indicate the most helpful diagnostic and treatment methods. PMID- 29599667 TI - Langerhans cell histiocytosis in children - a disease with many faces. Recent advances in pathogenesis, diagnostic examinations and treatment. AB - Langerhans cell histiocytosis is a rare clonal disease characterized by the proliferation of CD1a-positive immature dendritic cells. The purpose of this article was to present an updated review of recent advances in the pathogenesis, clinical features, imaging and treatment of this disease. The discovery of oncogenic BRAF mutations and the presence of proinflammatory cytokines and chemokines confirmed the unusual characteristics of this disease. Currently, children with organ involvement who do not have a good response to chemotherapy and have neurodegeneration or diabetes insipidus are the most problematic patients. Further research is needed to improve the results of treatment. PMID- 29599669 TI - X-linked TLR7 gene polymorphisms are associated with diverse immunological conditions but not with discoid lupus erythematosus in Polish patients. AB - Introduction: Toll-like receptor 7 (TLR7) is an important molecule involved in the development of autoimmunity and the response to different pathogens. Several polymorphisms within the TLR7 gene were previously found to be associated with systemic lupus erythematosus (SLE). However, none of those studies investigated the TLR7 promoter flanking variants rs1634318 and rs1616583. TLR7 gene diversity has not been analyzed with respect to discoid lupus erythematosus (DLE) development, while its role in the human immunological response to fungal infection is not fully known. Aim: To clarify the potential involvement of two novel single-nucleotide polymorphisms (SNPs) located in the TLR7 gene (rs1634318 and rs1616583) in a variety of immune-related conditions, we studied the variability of these loci in patients from a Polish population with SLE and DLE, as well as in immunocompromised patients who were affected by invasive aspergillosis (IA) and those who were not affected. Material and methods: Real time polymerase chain reaction was used to genotype SNPs. Statistically significant differences between case and control groups for both allele and genotype frequencies were assessed using the chi2 test with Yates' correction or two-tailed Fisher's exact test. The results were Bonferroni-corrected for multiple comparisons and odds ratios were calculated. Results: Two polymorphisms located in TLR7 might be associated with the development of SLE but not DLE within the Polish population. Moreover, variation of the two investigated SNPs was found to be associated with IA in immunocompromised Polish patients. Conclusions: In Polish patients, TLR7 promoter flanking gene polymorphisms might be associated with IA and SLE but not DLE. PMID- 29599670 TI - Dermoscopic assessment of skin toxicities in patients with melanoma during treatment with vemurafenib. AB - Introduction: The use of vemurafenib in melanoma has improved the survival of patients; however, it is associated with skin toxicities. Aim: To assess skin toxicities by dermoscopy in patients treated with vemurafenib. Material and methods: Eight patients with BRAF V600 mutation positive metastatic melanoma were examined dermoscopically during vemurafenib treatment. All skin lesions occurring during therapy were assessed clinically and dermoscopically using a hand-held dermoscope with polarised and non-polarised light. Skin lesions suspected for malignancy appearing during therapy were totally surgically excised with consecutive histopathological examination. Results: All 8 examined patients developed skin toxicity. The majority of patients (7/8) presented G1 skin toxicity according to CTCAE version 4.3. Only 1 of them had G2 skin toxicity. The most common dermoscopy findings in our study were hyperkeratotic verrucas in 5 patients (5/8) with structureless pattern. In some of them we also observed central dots, exophytic proliferation, hairpin vessels and homogeneous haemorrhage. Other findings were hyperkeratosis of the nipples (5/8) with brownish to yellowish, angular clods with a tendency to be more confluent in dermoscopy. Palmar plantar erythrodysaesthesia (3/8) showed dermoscopically a yellowish, homogeneous pattern. Four melanocytic skin lesions in 2 patients were surgically excised due to suspected malignant transformation. In most of them we observed an atypical pigmented network (abrupt cut-off, big holes), atypical globules and a homogeneous blue pattern; however, histopathological diagnosis excluded any malignancy. Conclusions: Dermoscopy seems to be an easily performed and valuable method for assessment of skin toxicities during oncological therapy, at any time of the treatment. PMID- 29599671 TI - Trends in basal cell carcinoma incidence rates: a 16-year retrospective study of a population in central Poland. AB - Introduction: Basal cell carcinoma (BCC) is the most commonly occurring cancer worldwide, and the overall incidence is still rising. Unfortunately, the cancer registry in Poland does not record BCC individually. Thus, the incidence of BCC in a defined population is unknown. Aim: Analysis of incidence rates of primary BCC in central Poland during 16 years considering sex, site distribution and age to determine trends. Material and methods: We retrospectively included all cases of BCC which were diagnosed and treated in the Department of Dermatology and Venereology, Medical University of Lodz, during the 16-year period from 1999 to 2015. Results: We recorded 945 BCCs occurring in 890 patients (504 females - 57%, 386 males - 43%). Patient's age was between 21 and 94. A distinct increase in BCC was observed after 1999, while after 2010 during the next 2-year period a slight decrease was noted. A statistically significant correlation was observed between histopathological types of BCC and the location of the lesions. The superficial type predominates on photoprotected areas, especially on the trunk, while the nodular type occurs mainly in facial areas. No statistically significant correlation was observed between histopathological types of BCC and sex. We found a significant increase in incidence for superficial BCC among middle-age patients, while the nodular type was observed more frequently among elderly subjects. Conclusions: Basal cell carcinoma is quite common in Poland and predominantly develops in the facial area. In middle-age patients the most common is superficial BCC, while in elderly people the nodular type is most common. Based on our results we assume that there is a strong need to educate general physicians to enable them to diagnose BCC in the early stages. PMID- 29599672 TI - The effect of subcutaneous methotrexate on markers of metabolic syndrome in psoriatic patients - preliminary report. AB - Introduction: Methotrexate (MTX) has anti-proliferative and anti-inflammatory effects in psoriasis. Moreover, low doses can reduce the risk of developing cardiovascular diseases. It turns out that psoriasis and atherosclerosis have a similar pathogenetic mechanism: the same pro-inflammatory cytokines, Th1 and Th17, are involved in both diseases. Aim: To evaluate the effects of metabolic markers, protective cytokines (interleukin 10 (IL-10), transforming growth factor beta (TGF-beta)) and a marker of endothelial damage (endocan) in patients with plaque psoriasis. Material and methods: The study included 24 patients aged 27-69 years (9 female, 15 male) with plaque psoriasis. The metabolic syndrome according to the International Diabetes Federation (IDF) was evaluated. The laboratory tests were performed under fasting conditions: C-reactive protein (CRP), glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL), uric acid, endocan, IL-10, and TGF-beta. After 12 weeks of treatment with MTX injections 15 mg/week, every patient was assessed with the same laboratory tests. Results: After treatment we observed a statistically significant increase of endocan and IL-10, but no significant differences in the titer of TGF-beta. C-reactive protein was reduced by approximately 54.7%. No improvement of lipid profile was observed, and even a significant increase in triglycerides was noted. Similarly, no significant difference was seen in the case of glucose and uric acid prior to and after treatment. Conclusions: Methotrexate in low doses in short-term treatment decreases CRP (anti-inflammatory effect) and increases endocan and IL 10 (potential protective role). Methotrexate is characterized by good efficacy and tolerability in therapy of patients with psoriasis. PMID- 29599673 TI - Associations between site of skin lesions and depression, social anxiety, body related emotions and feelings of stigmatization in psoriasis patients. AB - Introduction: Research has demonstrated a link between psoriasis and a multitude of psychological impairments; however, relatively few studies have examined the importance of site of skin lesions for negative psychological outcomes in psoriasis patients. Aim: To investigate relationships between anatomical location of psoriatic lesions and experiences of stigmatization, negative emotional attitude towards the body, depression and social anxiety. Material and methods: Adult psoriasis patients (N = 193) completed the Stigmatization Scale, the Body Emotions Scale, the Beck Depression Inventory and the Social Anxiety Questionnaire. The body surface area index was used to assess the location and extent of psoriasis. Results: Feelings of stigmatization were found to be most closely related to the presence of psoriatic lesions on the chest, and the arms and hands. Higher levels of social anxiety were found to be most closely related to the location of psoriatic lesions on the head and neck. Negative emotional attitude towards the body was found to be most closely related to the location of psoriatic lesions on the arms and hands, and on the head and neck. Higher levels of depressive symptoms were most closely related to the presence of psoriatic lesions on the head and neck, the arms and hands, and the genital area. Conclusions: The presence of psoriatic lesions on the head, neck, and chest, and also on the arms and hands and the genital area, should alert clinicians to a higher risk of psychological impairments. This may help to better recognize and prevent cumulative life course impairment. PMID- 29599674 TI - Epidemiology of urticaria in Poland - nationally representative survey results. AB - Introduction: The prevalence of urticaria is 15-20%. Women are twice as likely to be affected. Aim: To present the epidemiology of urticaria and angioedema in Poland. Material and methods: A questionnaire-based survey was conducted on a representative group of 4,897 individuals, aged 15-74 years. Results: A total of 11.2% of respondents reported at least one episode of urticaria symptoms in their life, and the frequency was higher in females (OR = 1.46; p < 0.001). Single episodes accounted for 34.8%, while repeated episodes accounted for 65.2%. Acute urticaria was observed in 10.6% (more frequent in females; OR = 1.41; p < 0.001), chronic in 0.6%. Median age of the first episode was 15 years. Angioedema was observed in 3.2%. The last episode of urticaria symptoms and/or angioedema occurred within the previous week in 0.7% of subjects, the last month in 1%, and the last year in 2.2%. 8.8% had experienced urticaria symptoms or angioedema over 1 year prior to the survey. The impact of urticaria symptoms on patients' daily activities was rated with 3.8 points on a scale of 0-10. In addition, chronic urticaria was rated 6.5, and acute urticaria 3.6. Angioedema and urticaria had a negative impact of 5.7 points. Conclusions: Urticaria and angioedema are serious health problems in Poland, although their prevalence is below the mean rate for the global population. Females are more likely to suffer from these diseases. People affected by urticaria most frequently report contact with plants and substances, insect bites/stings, and food as the provoking factors. PMID- 29599675 TI - Activity of antimicrobial peptides and conventional antibiotics against superantigen positive Staphylococcus aureus isolated from patients with atopic dermatitis. AB - Introduction: Staphylococcus aureus causes a diverse array of diseases, ranging from relatively harmless localized skin infections to life-threatening systemic conditions. It secretes toxins directly associated with particular disease symptoms. Aim: To determine the prevalence of methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) colonization among patients with atopic dermatitis and to assess the antimicrobial susceptibility to conventional antibiotics and selected antimicrobial peptides among toxin producing strains and nonproducing strains. Material and methods: One hundred patients with atopic dermatitis and 50 healthy people were microbiologically assessed for the carriage of S. aureus. Antimicrobial susceptibility tests were performed using the broth microdilution method for conventional antibiotics and antimicrobial peptides (CAMEL, Citropin 1.1, LL-37, Temporin A). Detection of genes lukS/lukF-PV, tst, sea-sed, eta and etb by multiplex PCR was performed. Results: Staphylococcus aureus strains were isolated from the majority of patients, from either the skin (75%) or the anterior nares (73%). Among the conventional antibiotics tested, the highest rates of resistance were observed for ampicillin, daptomycin, lincomycin and erythromycin. Antimicrobial peptides did not show significant diversity in activity. Among MSSA strains greater differentiation of secreted toxins was observed (sec, eta, pvl, tsst, etb, seb), while in the group of MRSA strains secretion of 3 toxins (pvl, eta, seb) was noted. Conclusions: Antimicrobial resistance continues to evolve. It is important to monitor S. aureus infections. The profile of toxins produced by S. aureus strains is an important consideration in the selection of an antimicrobial agent to treat infections. PMID- 29599676 TI - Cross-sensitization to Artemisia and Ambrosia pollen allergens in an area located outside of the current distribution range of Ambrosia. AB - Introduction: The role of long-distance transported (LDT) Ambrosia pollen in inducing new sensitization and affecting sensitization rates in Artemisia sensitized patients is unclear. Aim: The aim of this study was to estimate the degree of cross-sensitization to Ambrosia/Artemisia allergens in citizens of Poznan (Western Poland). This area is covered by extensive Artemisia populations but does not currently have local Ambrosia populations. Material and methods: Sera of 119 patients were tested by fluoroenzyme immunoassay (CAP-FEIA system) against pollen allergen extracts of Artemisia vulgaris and Ambrosia artemisiifolia, an allergenic component of A. vulgaris (nArt v 1), and an allergenic component of A. artemisiifolia (nAmb a 1). Skin prick tests (SPTs, n = 86) were performed with pollen allergen extracts of A. vulgaris and A. artemisiifolia. Artemisia and Ambrosia pollen in ambient air was collected (1996 2013) by a Hirst type volumetric trap sited at roof level (33 m). Results: The SPT showed that the prevalence of sensitization to Ambrosia and Artemisia pollen exceeded 3.5%, and 10.5%, respectively. The measurements of IgE in blood serum (CAP-FEIA) revealed that among Ambrosia-sensitized patients 90.1% (20/22 patients) were concomitantly sensitized to Artemisia. 59.1% (13/22) of these patients reacted to nArt v 1, suggesting primary sensitization to Artemisia pollen. Only 2 (9.1%) patients were mono-sensitized to Ambrosia pollen extract, but surprisingly not to nAmb a 1. Conclusions: The LDT Ambrosia pollen had a negligible effect on the rate of sensitization to Ambrosia allergens in Poznan and did not increase the prevalence of sensitization to Artemisia pollen in this region. However, the majority of patients showing hypersensitization to Artemisia pollen might also present symptoms during elevated episodes of LDT of Ambrosia pollen. PMID- 29599677 TI - Venom immunotherapy and pregnancy. AB - Introductions: The efficiency of venom immunotherapy (VIT) has been well documented by many studies. However, the most important for VIT is safety, particularly for a pregnant woman and a fetus. Aim: To establish the influence of continuation of VIT on pregnant women and offspring. Material and methods: The 6 women became pregnant during a specific immunotherapy. We retrospectively analyzed the influence of the immunotherapy on any complications for the pregnant women and their infants. Results: Of the 6 patients who participated in this study, four had hyperemesis gravidarum, nausea, and heartburn, and two of them had gestational diabetes mellitus symptoms, typical of pregnancy. The observation indicated that VIT was safe for the pregnant women and their offspring. Conclusions: The VIT is an appropriate therapeutic method for most patients with severe anaphylactic reactions after a hymenoptera sting. The observation indicated that VIT is safe for pregnant women and for their infants. PMID- 29599678 TI - The usefulness of the basophil activation test in monitoring specific immunotherapy with house dust mite allergens. AB - Introduction: In clinical practice, reliable tools for monitoring specific immunotherapy (SIT) are of utmost importance. Aim: To assess the usefulness of the basophil activation test (BAT) in monitoring SIT in paediatric patients with allergy to house dust mites (HDM). Material and methods: Thirty-one children qualified for SIT with HDM, of whom 21 completed the SIT during the observation period. The BAT was carried out prior to commencing the SIT (time point BAT1) and upon finishing the initial pack of allergy vaccine (cumulative dose of allergen 12487.5 PNU; BAT2), as well as after the second vaccine pack (cumulative dose of allergen 23750.0 PNU; BAT3). Peripheral blood of the patients was stimulated with allergen solutions in five concentrations from 0.00225 ng/ml to 22.5 ng/ml. Basophil activation was measured by CD63 expression in flow cytometry. Results: For the allergen concentration of 0.225 ng/ml, a statistically significant decrease in median basophil activation was observed, from 51.29% at BAT1 to 8.48% at BAT2 (p = 0.004) and 4.21% at BAT3 (p < 0.001). For the allergen concentration of 0.0225 ng/ml, a statistically significant decrease was seen between BAT1 (1.72%) and BAT3 (0.21%, p = 0.01). Median CD-sens index decreased significantly from 1099.02 at BAT1 to 179.31 at BAT2 (p < 0.002) and 168.04 at BAT3 (p < 0.001). Conclusions: There is a significant decrease in BAT results in the course of specific immunotherapy with HDM allergens in children, with the optimum allergen concentration for monitoring basophil response at 0.225 ng/ml. The CD sens index seems to be a better monitoring parameter than the plain percentage of CD63-expressing basophils. PMID- 29599679 TI - Seasonal variation of asthma control, lung function tests and allergic inflammation in relation to vitamin D levels: a prospective annual study. AB - Introduction: There are scarce data about the role of vitamin D (vitD) in asthma control related to seasons and other confounders. Aim: To investigate the seasonal relationship between vitD levels and asthma control, lung function tests (LFTs) and cytokines during a 1-year period, among 7-17-year-old asthmatic children. Material and methods: Thirty patients with asthma with house dust mite monosensitization were evaluated 3 monthly about the previous month's health and vitD related lifestyle factors and asthma control test (ACT), spirometry and bronchial provocation test for a year. Serum vitD, vitD binding protein (VDBP), total IgE levels, absolute eosinophil and Treg counts and cytokine levels were simultaneously measured. The seasonal changes of vitD and other parameters and the relationship between 120 pooled data sets of vitD and major outcomes were evaluated. Results: Mean vitD levels, forced expiratory volume in 1 s (FEV1%) and ACT score were lowest in winter and highest in summer. Pooled vitD levels were positively correlated with pooled ACT scores, Treg counts, FEV1% values and VDBP levels and negatively with total immunoglobulin E (IgE) and interleukin-4 (IL-4) levels and bronchodilator response. VitD levels were positively associated with ACT score, and FEV1% value and negatively with serum IgE level and bronchodilator response after adjusting for confounders. Conclusions: This study revealed that asthma control measures, LFTs and IgE levels were significantly related to serum vitD levels, independent from age, body mass index, inhaled corticosteroid use, sun exposure and season among asthmatic children. Vitamin D levels showed a positive correlation with Treg counts and a negative correlation with Th2 type cytokines.

AB - This study was conducted to research and develop recommendations for gender transformative approaches that will address misconceptions around food and nutrition, and reducing barriers around dietary diversity within rural Khatlon Province, Tajikistan. Most of the population in Tajikistan live in rural areas and spend a large part of their income on food. While stunting in children under 5 years has decreased, acute malnutrition and the number of underweight children has increased. This is a qualitative, cross-sectional study that involved secondary data analysis, key informant interviews (KIIs), and focus group discussions (FGDs) to gauge appropriate interventions for agricultural extension agents seeking to improve the nutritional outcomes of their communities. In February of 2017, data were collected from 4 KIIs and 15 FGDs that were stratified as mothers with young children, mothers-in-law, and husbands, across 12 different villages. Analysis of the KIIs and FGDs included NVivo software for coding and to uncover the most salient themes and characteristics from each. The participants of this study reported several misconceptions and taboos surrounding certain foods, especially during pregnancy, and food practices for children under the age of 5 years. Results also indicated a household hierarchy of decision making surrounding food that included who buys, cooks, and decides what to buy. The findings of this study will be used as a springboard to launch gender responsive and nutrition-sensitive interventions through the local agricultural extension agents. PMID- 29599686 TI - Alignments of endocrine, anthropometric, and metabolic parameters in type 2 diabetes after intervention with an Okinawa-based Nordic diet. AB - Background: An Okinawa-based Nordic diet with moderately low carbohydrate content and high fat and protein content has been shown to improve anthropometry and metabolism in type 2 diabetes. Objective: The objectives of this study were to measure plasma or serum levels of hormones regulating energy metabolism and metabolic control, that is, cholecystokinin (CCK), Cortisol, C-peptide, ghrelin, glucagon, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), insulin, leptin, plasminogen activator inhibitor-1 (PAI-1), polypeptide YY (PYY), resistin, and visfatin after this diet intervention, and to determine partial correlations between hormonal levels and anthropometric and metabolic responses. Design: A total of 30 patients (17 women) with type 2 diabetes, mean age 57.5 +/- 8.2 years, and body mass index (BMI) 29.9 +/- 4.1 kg/m2 were served the diet for 12 weeks. Fasting hormones were measured by Luminex and enzyme-linked immunosorbent assay (ELISA) before study start and after 12 and 28 weeks, along with anthropometric and metabolic parameters. Result: The levels of CCK (P = 0.005), cortisol (P = 0.015), C-peptide (P = 0.022), glucagon (P = 0.003), GLP-1 (P = 0.013), GIP (P < 0.001), insulin (P = 0.004), leptin (P < 0.001), and PYY (P < 0.001) were lowered after dietary intervention. These reduced levels only remained for PYY at week 28 (P = 0.002), when also ghrelin (P = 0.012) and visfatin (P = 0.021) levels were reduced. Changes of glucose values correlated with changed levels of C-peptide and PYY (P < 0.001), insulin (P = 0.002), and PAI-1 (P = 0.009); changes of triglyceride values with changed levels of C-peptide, insulin, and PYY (P < 0.001) and PAI-1 (P = 0.005); changes of insulin resistance with changes of leptin levels (P = 0.003); and changes of BMI values with changed levels of C-peptide, insulin, and leptin (P < 0.001). Conclusions: Okinawa-based Nordic diet in type 2 diabetes has significant impact on the endocrine profile, which correlates with anthropometric and metabolic improvements. PMID- 29599687 TI - Knowledge, attitudes, and practices of health-care workers regarding hand hygiene guidelines in Al-Qassim, Saudi Arabia: A multicenter study. AB - Introduction: Hand hygiene is one of the most important ways to reduce the prevalence of nosocomial infections, morbidity, mortality, and health-care costs among hospitalized patients worldwide. Objectives: We addressed this study to assess knowledge, attitudes, and practices regarding hand hygiene guidelines among health-care workers. Methods: A multicenter cross-sectional study conducted from October to December 2015 including three hospitals in Al-Qassim, Saudi Arabia. A total of 354 participants completed a self-administered survey on knowledge, attitudes, and practices of hand hygiene. Analysis of variance was used to compare knowledge level across age, gender, profession, and hospitals. All analyses were performed with SPSS, version 21. Results: Overall, the average knowledge score was 63%. There were significant differences in knowledge level across groups. Health-care workers over the age of 30 had higher scores than those younger than 30. Health-care workers at the tertiary hospital had higher scores than those at the secondary hospitals. Nearly, all reported positive attitudes toward hand hygiene as well as adhering to the guidelines regularly. Further, they reported that soap and water were the most common agents for cleaning hands. Conclusion: The study findings indicate that there are gaps in the knowledge, which could be addressed with brief and more frequent training sessions, particularly in the secondary hospitals. However, the hand hygiene guidelines are well-known by the staff and well promoted in the hospitals reflected by the positive attitudes. Further improvements in adherence to the hand hygiene guidelines will continue to decrease the likelihood of nosocomial infections. PMID- 29599688 TI - Knowledge, attitude, and practice toward evidence-based medicine among hospital physicians in Qassim Region, Saudi Arabia. AB - Objectives: To determine the knowledge, attitude, and practice regarding evidence based medicine (EBM) among hospital physicians in Qassim region of Saudi Arabia. Methods: It is a cross-sectional study. A self-administered questionnaire survey was done among 288 physicians working in secondary and tertiary care centers. The study was conducted between June and September 2015. Results: The overall response rate for the survey was 72%. Majority of the respondents had a positive attitude toward EBM and welcomed the concept. A total of 83% respondents stated that they used EBM in their daily practice and 93.5% agreed that practicing EBM improves patient care. There was a moderate level of awareness regarding extracting information from journals and clinical evidence databases. Although the respondents were aware and demonstrated familiarity with the process of knowledge extraction procedures to determine the best care, as many as 40% did not use them. The respondents had a poor overall understanding of the technical terms used in EBM. Among the respondents, 38.5% thought that the best way to move from opinion-based medicine to EBM was through learning the skills of EBM. The factors that positively affected physician awareness included: Academic qualification and professional title. Knowledge and attitude were affected by qualification, professional title and specialty. Conclusion: The attitude of most physician practitioners in this study is favorable toward EBM, but this was not correlated with knowledge and awareness. The inclusion of physician training courses in EBM concepts, technical terms and applied practice is highly recommended. PMID- 29599689 TI - Validity and reliability of the Arabic version of the the EuroQOL (EQ-5D). A study from Saudi Arabia. AB - Objectives: The EuroQOL five-dimension questionnaire (EQ-5D) is one of the most widely used tools to evaluate health-related quality of life (HRQOL). Studies on the psychometric features of the EQ-5D in the Gulf region of the Middle East are lacking. This study is aimed at evaluating the validity and reliability of the Arabic version of the EQ-5D in Saudi Arabia. Methods: The study was done utilizing a convenience sample of Arabic-speaking adult patients or visitors at the outpatient clinic at King Abdulaziz Medical City (KAMC) in Riyadh during October-December 2015. Participants were interviewed using translated into Arabic versions of the EQ-5D and the Short Form Health Survey (SF-36). Known-group construct validity of the EQ-5D and visual analog scale (EQ-VAS) was assessed through testing a number of hypotheses comparing responses to EQ-5D dimensions or EQ-VAS to SF-36 scores by dimension and external variables. Test-retest reliability was also assessed. Results: Eighty subjects were included in the study. Mean +/- standard deviartion age was 33.0 +/- 11.6 years, with 51% of females. Responses to EQ-5D dimensions revealed that the proportion of respondents reporting problems ranged from 6% for problems with self-care to 48% for pain/discomfort. All of the five hypotheses linking EQ-5D responses to external variables were satisfied. Test-retest reliability was evaluated using Cohen's kappa, which ranged from 0.53 to 1.00. Conclusion: Validity and reliability of the Arabic EQ-5D were established for evaluating HRQOL in Saudi Arabia. Further studies are warranted to evaluate the validity and reliability of this standard tool in other Arabic-speaking countries with varying cultures.

AB - Objectives: The main goal of this study was to evaluate the fracture resistance of maxillary second premolar teeth with standard and conservative mesio-occluso distal (MOD) cavity designs. Methods: Sixty maxillary second premolars were randomly divided into 6 Groups of 10 teeth. G1 consisted of intact teeth. G2 was prepared with separated proximal boxes that were designed to be 1 mm approximately above the cement-enamel junction for the cervical margins. The occlusal outline of the proximal was performed as approximately half of the intercuspal distance buccolingually and one-third of the mesiodistal dimension. The proximal preparation was standardized in all tested groups. G3 was prepared with an occlusal extension that extended approximately one-third of buccolingual width and 2 mm in depth. G4 was prepared with the occlusal extension of 1mm in depth and width. G5: The occlusal extension was 1mm in depth and 2 mm in width. G6: The occlusal extension was 2 mm in depth and 1 mm in width. Samples were restored with composite resin and subjected to load to failure test to evaluate the fracture resistance. Results: G1 showed the highest fracture resistance value (1737.1 N) while G3 had the lowest mean value (522.9 N). Furthermore, the fracture resistance of G4 and G5 was significantly higher than G3 and G6 (P < 0.05), where in both groups, the preparation of the occlusal extension mostly remained in the enamel layer. Conclusion: Modified MOD cavity designs with 1 mm depth in the enamel layer have significantly higher fracture resistance than the standard MOD cavity.

AB - Objective: The present work evaluated histologically and immunohistochemically the expression of leptin during healing of the incisional oral mucosal wound in diabetic rats as compared to healthy rats. Methods: Twenty-four adult male Sprague-Dawley rats weighing on average 150-200 g were allocated equally into two groups: Group I (control) and Group II (diabetic). Diabetes was induced by a single intraperitoneal injection of streptozotocin dissolved in distilled water. Each animal received experimental incision in buccal mucosa and sutured, and the specimens were collected from the buccal mucosa of each animal at intervals of 7, 14, and 21 days and routinely processed for H and E and immunohistochemical staining for leptin. All measurement data were calculated as a mean +/- standard deviation. Results: Leptin expression was observed in the epithelium and the vascular endothelial cells in both groups. In both the control and diabetic groups, the expression of leptin was significantly increased with time, and there was an extreme highly significant increase in the control group than in diabetic group after 7, 14, and 21 days (P = 0.000). Conclusion: The results of the present study suggested that leptin may promote wound healing in rat's normal oral mucosa more than in diabetic. Further studies are needed to clarify the exact molecular mechanisms of leptin's effects on wound healing and to determine the usefulness of leptin as a treatment to promote wound healing in the oral mucosa in diabetic and non-diabetic patients. PMID- 29599692 TI - Barriers to effective feedback in undergraduate medical education: Case study from Saudi Arabia. AB - Objectives: Students' feedback is an essential source of data for evaluation and improvement of the quality of education. Nonetheless, feedback may be routinely practised for accreditation purposes, and it is considered as a ritual employed by students, which makes its effectiveness questionable. The aim of this study is to explore and analyze the students' perceptions about the importance of feedback and the barriers for effective feedback and suggest proper ways to overcome these barriers. Methods: This cross-sectional, anonymous, questionnaire-based study was conducted in the College of Medicine, Qassim University. A total of 299 medical students, composed of 185 male and 114 female, from different levels during December 2015 participated. Mean value, standard deviation, and proportion were used to quantify the quantitative and categorical study and outcome variables. Results: 47% of students responded to the questionnaire with more participation of juniors and females. Half of the students believed that feedback is not important and agreed for the presence of barriers for effective feedback. 5th level students exhibited higher resistance for participation in feedback, and there was a significant difference between male and female students. Promisingly, most of the participant did not believe the presence cultural barrier for feedback. Conclusion: Saudi medical students are willing to involve in effective feedback. Some barriers that make feedback practised as tokenistic is present. They can be overcome through proper orientation and appropriate closing the loop with response to the feedback declared to students. Further investigation is needed to explore barriers to feedback in higher education settings and help designing an approach to enhance the effectiveness of feedback on a national level. PMID- 29599693 TI - Functional analysis of lower limbs in individuals infected with the human immunodeficiency virus. AB - Objectives: The objective of this research was to analyze the functional changes of lower limbs by means of surface electromyography in patients with acquired immunodeficiency syndrome. Methods: A total of 60 men and women (age mean of 36.77 +/- 9.33 years) were divided into two groups: 30 individuals with human immunodeficiency virus group (HIVG) Subtype 1 and 30 healthy individuals control group. Muscle activity was evaluated using surface electromyography (sEMG). sEMG measurements were made while the subjects assumed the static positions: Rest in orthostatism (RS), squat "normalization factor," right and left single leg support (RSLS, LSLS) and during functional activities: Right and left single leg step rise (RSLSR, LSLSR), right and left single leg step down (RSLSD, LSLSD), rising and seating on a chair (RC, SC). Results: To sEMG results revealed statistically significant values in the conditions of RSLS to left semitendinosus muscle, for LSLS to right and left semitendinosus, right rectus femoris and right gluteus medius muscles, for LSLSR to right rectus femoris and right tensor fasciae latae muscles, for RSLSD to right and left semitendinosus and right rectus femoris muscles, for RC to right rectus femoris and left gluteus medius muscles and for SC to right semitendinosus, right rectus femoris and right and left gluteus medius muscles. Conclusion: It can be concluded that individuals with acquired immunodeficiency syndrome presented changes in lower limb muscle activity. PMID- 29599694 TI - Utilization of clinical pathway on open appendectomy: A quality improvement initiative in a private hospital in the Philippines. AB - Objective: This study was done to evaluate the utilization of clinical pathway (CP) on open appendectomy as a quality improvement (QI) initiative. Methods: The CP document was developed from the clinical practice guideline created by the Philippine College of Surgeons using an event-timeline tabular checklist format. After a hospital-wide education, the CP was implemented on January 1, 2010, as the QI intervention. Appendectomies done 4 years before the intervention were assigned to the pre-pathway group while those done 5 years after were assigned to the post-pathway group. Demographic data were collected including the different clinical outcomes such as the average length of stay (ALOS), comorbidity, diagnostic modality used, hospital cost, and variance rate. Data were presented as mean +/- standard deviation and percentage which ever were applicable. Statistical analysis was done using Student t-test for numerical data and Chi square for dichotomous data. Significance was set at P < 0.05. Results: Two hundred ninety-five patients were included in the study. Separate analysis was done for uncomplicated (Pre-pathway Group, n = 49 and Post-pathway group, n = 139) and complicated (pre-pathway Group, n = 38 and Post-pathway Group, n = 69) open appendectomies. Results showed that diagnosis was achieved through history and physical examination. Ultrasound use did not significantly differ between groups and types of open appendectomy. Major findings showed a significant decrease in ALOS, hospitalization cost, and variance in the post-pathway group compared with the pre-pathway group (P < 0.05). Conclusion: These findings supported the use of CP in QI of health care in commonly done surgeries like appendectomy. PMID- 29599695 TI - Persistent anxiety and in-hospital complications after acute coronary syndrome. AB - Objectives: To investigate the effects of pre-event persistent anxiety on in hospital complications and length of stay (LOS) in patients who experienced acute coronary syndrome (ACS). Methods: This was a prospective study with patients seeking treatment for ACS events. Anxiety was measured 2 times before the event in 600 patients with pre-existing coronary heart disease (CHD). Patients were followed for 2 years or until they developed an ACS event. 120 patients developed ACS events (rate 20%). Complications and LOS were abstracted from medical records. Results: Persistently non-anxious patients have lower anxiety scores at 3 months follow-up than baseline (mean [standard deviation (SD)], 6.1 [0.24] vs. 3.9 [0.95], P <0.01). Patients with persistent anxiety had significantly higher complication rates than non-anxious patients (mean [SD], 0.71 [0.12] vs. 0.15 [0.11], P <0.05). In a multiple logistic regression, persistent anxiety was an independent predictor of complications. Patients who were persistently anxious were at 5 times higher risk for developing complications (odds ratio = 5.0, 95% confidence interval: 1.27-38.8, P < 0.05). Conclusion: Anxiety measured up to 2 years before an ACS event was predictive of in-hospital complications. Clinicians caring for patients with CHD need to be as equally aware of the importance of assessing and treating persistent anxiety as clinicians caring for patients hospitalized for an ACS. PMID- 29599696 TI - Merits of trabeculectomy in advanced and end-stage glaucoma. AB - Objectives: The aim of the study was to evaluate intraocular pressure (IOP) control, potential benefits, and associated complications in advanced cases of glaucoma (visual acuity of <6/60) after trabeculectomy. Although many studies of trabeculectomy in glaucoma patients have been done, very few in such advanced cases. Methods: The study was done on 60 cases of advanced primary open-angle glaucoma (POAG). Trabeculectomy was done and IOP control was assessed. Pre operative workup included a detailed history, slit lamp biomicroscopy, Goldmann applanation tonometry, gonioscopy using Goldmann 2 mirror lens, and detailed fundus examination with the 78D lens. All the patients were to undergo optical coherence tomography and Humphrey automated perimetry. Results: Out of 60 patients with POAG, 48 were males and 12 were females with a ratio of 4:1. Of all the 60 cases, 36 had a visual acuity of 20/200, 16 had a visual acuity of hand movements, and eight patients had a visual acuity of perception of light. The mean pre-operative IOP was measured as 37.01 mmHg with standard deviation (SD)+/- 8.82. The mean post-operative IOP was found 17.92 mmHg with SD +/- 3.17. There was a mean drop of 19 mmHg of IOP postoperatively. P value was highly significant (P < 0.000). Conclusion: Trabeculectomy is a successful method of controlling IOP in patients with advanced glaucoma. Trabeculectomy is the method of reducing IOP in medically uncontrolled patients. A pain-free eye was associated with better quality of life in patients. A successful trabeculectomy helps to preserve the residual vision in such patients. PMID- 29599697 TI - Links between the Prophet Muhammad (PBUH) recommended foods and disease management: A review in the light of modern superfoods. AB - Nutrition and other bioactive natural products present in specific foods within a balanced diet play an indispensable role in maintaining and promoting human health. Plants are rich sources of a balanced nutrition because of high content of bioactive products; hence, most of them recently have acquired the status of superfoods. It has been used since ancient times for the treatment of various ailments, and these traditional medicines still remain as one of the most affordable and easily accessible sources of treatment in the primary health-care system. The scientifically based use of these superfoods date back to the era of Prophet Muhammad along with other historical uses of plant products. Prescription of a large number of herbal foods such as dates, pomegranate, olives, figs, grapes, and black seeds was successfully proposed by him. These recently have become superfoods with their powerful healing properties and act as favorable dietary interventions for disease prevention as well as for the good maintenance of health. The use of these foods as ingredients of natural origin with fewer side effects seems to be more favorable than the chemical treatment, which is often complicated. The present review is an attempt to provide a brief survey of the literature on scientifically based significance of these superfoods carried out by various researchers and exploration of a wide spectrum of their pharmacological actions which include antidiabetic, anticancer, immune modulator, analgesic, anti-inflammatory, and hepatoprotective properties. PMID- 29599699 TI - A literature review of empirical research on learning analytics in medical education. AB - The number of publications in the field of medical education is still markedly low, despite recognition of the value of the discipline in the medical education literature, and exponential growth of publications in other fields. This necessitates raising awareness of the research methods and potential benefits of learning analytics (LA). The aim of this paper was to offer a methodological systemic review of empirical LA research in the field of medical education and a general overview of the common methods used in the field in general. Search was done in Medline database using the term "LA." Inclusion criteria included empirical original research articles investigating LA using qualitative, quantitative, or mixed methodologies. Articles were also required to be written in English, published in a scholarly peer-reviewed journal and have a dedicated section for methods and results. A Medline search resulted in only six articles fulfilling the inclusion criteria for this review. Most of the studies collected data about learners from learning management systems or online learning resources. Analysis used mostly quantitative methods including descriptive statistics, correlation tests, and regression models in two studies. Patterns of online behavior and usage of the digital resources as well as predicting achievement was the outcome most studies investigated. Research about LA in the field of medical education is still in infancy, with more questions than answers. The early studies are encouraging and showed that patterns of online learning can be easily revealed as well as predicting students' performance. PMID- 29599698 TI - The effectiveness of alitretinoin for the treatment of chronic hand eczema: A meta-analysis. AB - Alitretinoin is a new oral retinoid authorized for use in grownups that have severe chronic hand eczema (CHE). A comprehensive search to solicit all studies of alitretinoin for the treatment of CHE. A comprehensive search to solicit all studies of alitretinoin for the treatment of CHE including randomized controlled trials (RCTs) or uncontrolled trials, re-treatment studies, open-label studies, or observational studies, along with case series of 10 or more participants. Physician global assessment (PGA), patient global assessment (PaGA) and modified total lesion symptom score (mTLSS) are the methods and outcomes criteria. Generated effect size and 95% confidence intervals were calculated for the outcomes. Heterogeneity and publication bias were also tested for all selected trials. When a noteworthy Q statistic (P < 0.1) demonstrates the heterogeneity crosswise over studies, an arbitrary impact model is used. On the other hand, a settled effect model is when heterogeneity is not shown. The initial search yielded 408 records of which 15 articles were selected. The 15 clinical trials included 3734 patients with CHE. Among alitretinoin-treated patients, the PGA effect size was directly proportional to the drug dosage, ranging from 40% to 69%, while the PaGA score ranged from 28.8% to 62.4%, and mTLSS ranged from 60.4% to 76.9%, much higher than placebo. A higher drug dose was about twice as effective as lower dose. The odds ratio for a better outcome with drug treatment taking duration into account was about 3-4 times that versus placebo. In conclusions, alitretinoin cleared lesions in about 50% of cases, particularly using a higher dose for a longer duration. PMID- 29599700 TI - Effect of testosterone boosters on body functions: Case report. AB - Testosterone boosters are supplementary substances that can be used for the purpose of increasing testosterone levels in the blood. This study aimed to evaluate the side effects and health risks of testosterone boosters among athletes. A sportsman came to the King Saud Hospital, Unaizah, Qassim, Saudi Arabia, suffering from abdominal pain. The attending doctor requested general laboratory tests. He admitted to having consumed two courses of a testosterone booster over a period of 42 days following the instructions of the manufacturer. In total, the athlete in question consumed several courses, twice before the abdominal pain started and twice after it subsided. The blood tests and reports suggested that the commercial product consumed might negatively affect several hepatic functions and resulted in slightly increased testosterone concentrations after the fourth course. In conclusion, administration of testosterone booster products, although obtained from trusted sources, may still present some health risks. Further studies with large sample size and for a long period need to be done to confirm the current findings. PMID- 29599701 TI - Rare case of a mandibular first molar with seven canals confirmed by cone beam computed tomography and its endodontic management. AB - The endodontic treatment of a mandibular molar with aberrant canal configuration can be diagnostically and clinically challenging. This case report presents the treatment of a mandibular first molar with seven root canals, of which four canals were located in the mesial root and three in distal root. This case presents a rare anatomic configuration and points to the importance of expecting and searching for additional canals. PMID- 29599702 TI - Age-Related Changes in Neuromodulatory Control of Bladder Micturition Contractions Originating in the Skin. AB - The brainstem is essential for producing micturition contractions of the urinary bladder. Afferent input from perineal skin evoked by gentle mechanical stimulation inhibits micturition contractions by decreasing both ascending and descending transmissions between the brainstem and spinal cord. Dysfunction of this inhibitory mechanism may be one cause of the increase in the prevalence of overactive bladder in old age. The aim of this study was to examine effect of aging on function of skin afferent fibers that inhibit bladder micturition contractions in rats. We used anesthetized male rats in three different age groups: young adult (4-5 months old), middle aged (6-9 months old), and aged (27 30 months old). The bladder was expanded to produce isovolumetric rhythmic micturition contractions. Skin afferent fibers were activated for 1 min either by electrical stimulation (0.5 ms, 0.2-10 V, 0.1-10 Hz) of the cutaneous branch of the pudendal nerve (CBPN) or by gentle mechanical skin stimulation with an elastomer roller. When skin afferent nerves were activated electrically, micturition contractions were inhibited in a similar manner in all age groups, with long latency inhibition induced by excitation of Abeta fibers and short latency inhibition by additional Adelta and C fiber excitation (at 1-10 Hz). On the contrary, when skin afferent nerves were activated mechanically by rolling, latency of inhibition following rolling stimulation was prolonged in aged rats. Single unitary afferent nerve activity of low-threshold mechanoreceptors (LTMs) from the cutaneous nerve was recorded. The discharge rate during rolling was not significantly reduced in Abeta units but was much lower in Adelta and C units in aged rats (0.4 and 0.5 Hz, respectively) than in young adult rats (3 and 7 Hz). These results suggest that the neural mechanism that inhibits bladder micturition contractions by skin afferent input is well maintained in old age, but the early inhibition by gentle skin stimulation is decreased because of reduced responses of Adelta- and C-LTMs. PMID- 29599703 TI - SP8 Transcriptional Regulation of Cyclin D1 During Mouse Early Corticogenesis. AB - Multiple signals control the balance between proliferation and differentiation of neural progenitor cells during corticogenesis. A key point of this regulation is the control of G1 phase length, which is regulated by the Cyclin/Cdks complexes. Using genome-wide chromatin immunoprecipitation assay and mouse genetics, we have explored the transcriptional regulation of Cyclin D1 (Ccnd1) during the early developmental stages of the mouse cerebral cortex. We found evidence that SP8 binds to the Ccnd1 locus on exon regions. In vitro experiments show SP8 binding activity on Ccnd1 gene 3'-end, and point to a putative role for SP8 in modulating PAX6-mediated repression of Ccnd1 along the dorso-ventral axis of the developing pallium, creating a medialLow-lateralHigh gradient of neuronal differentiation. Activation of Ccnd1 through the promoter/5'-end of the gene does not depend on SP8, but on betacatenin (CTNNB1). Importantly, alteration of the Sp8 level of expression in vivo affects Ccnd1 expression during early corticogenesis. Our results indicate that Ccnd1 regulation is the result of multiple signals and that SP8 is a player in this regulation, revealing an unexpected and potentially novel mechanism of transcriptional activation. PMID- 29599704 TI - Pacing Hippocampal Sharp-Wave Ripples With Weak Electric Stimulation. AB - Sharp-wave ripples (SWRs) are spontaneous neuronal population events that occur in the hippocampus during sleep and quiet restfulness, and are thought to play a critical role in the consolidation of episodic memory. SWRs occur at a rate of 30 200 events per minute. Their overall abundance may, however, be reduced with aging and neurodegenerative disease. Here we report that the abundance of SWR within murine hippocampal slices can be increased by paced administration of a weak electrical stimulus, especially when the spontaneously occurring rate is low or compromised. Resultant SWRs have large variations in amplitude and ripple patterns, which are morphologically indistinguishable from those of spontaneous SWRs, despite identical stimulus parameters which presumably activate the same CA3 neurons surrounding the electrode. The stimulus intensity for reliably pacing SWRs is weaker than that required for inducing detectable evoked field potentials in CA1. Moreover, repetitive ~1 Hz stimuli with low intensity can reliably evoke thousands of SWRs without detectable LTD or "habituation." Our results suggest that weak stimuli may facilitate the spontaneous emergence of SWRs without significantly altering their characteristics. Pacing SWRs with weak electric stimuli could potentially be useful for restoring their abundance in the damaged hippocampus. PMID- 29599706 TI - Lipoprotein Lipase Is a Feature of Alternatively-Activated Microglia and May Facilitate Lipid Uptake in the CNS During Demyelination. AB - Severe demyelinating disorders of the central nervous system (CNS) such as multiple sclerosis (MS), can be devastating for many young lives. To date, the factors resulting in poor remyelination and repair are not well understood, and reparative therapies that benefit MS patients have yet to be developed. We have previously shown that the activity and abundance of Lipoprotein Lipase (LPL)-the rate-limiting enzyme in the hydrolysis of triglyceride-rich lipoproteins-is increased in Schwann cells and macrophages following nerve crush injury in the peripheral nervous system (PNS), suggesting that LPL may help scavenge myelin derived lipids. We hypothesized that LPL may play a similar role in the CNS. To test this, mice were immunized with MOG35-55 peptide to induce experimental allergic encephalomyelitis (EAE). LPL activity was increased (p < 0.05) in the brain at 30 days post-injection, coinciding with partial remission of clinical symptoms. Furthermore, LPL abundance and activity was up-regulated (p < 0.05) at the transition between de- and re-myelination in lysolecithin-treated ex vivo cerebellar slices. Since microglia are the key immune effector cells of the CNS we determined the role of LPL in microglia. Lipid uptake was decreased (p < 0.001) in LPL-deficient BV-2 microglial cells compared to WT. In addition, LPL deficient cells showed dramatically reduced expression of anti-inflammatory markers, YM1 (-22 fold, p < 0.001), and arginase 1 (Arg1; -265 fold, p < 0.001) and increased expression of pro-inflammatory markers, such as iNOS compared to WT cells (+53 fold, p < 0.001). This suggests that LPL is a feature of reparative microglia, further supported by the metabolic and inflammatory profile of LPL deficient microglia. Taken together, our data strongly suggest that LPL expression is a novel feature of a microglial phenotype that supports remyelination and repair through the clearance of lipid debris. This mechanism may be exploited to develop future reparative therapies for MS and primary neurodegenerative disorders (Alzheimer's disease (AD) and Parkinson's disease). PMID- 29599707 TI - Brain-Derived Neurotrophic Factor Elevates Activating Transcription Factor 4 (ATF4) in Neurons and Promotes ATF4-Dependent Induction of Sesn2. AB - Activating transcription factor 4 (ATF4) plays important physiologic roles in the brain including regulation of learning and memory as well as neuronal survival and death. Yet, outside of translational regulation by the eIF2alpha-dependent stress response pathway, there is little information about how its levels are controlled in neurons. Here, we show that brain-derived neurotrophic factor (BDNF) promotes a rapid and sustained increase in neuronal ATF4 transcripts and protein levels. This increase is dependent on tropomyosin receptor kinase (TrkB) signaling, but independent of levels of phosphorylated eIF2alpha. The elevation in ATF4 protein occurs both in nuclei and processes. Transcriptome analysis revealed that ATF4 mediates BDNF-promoted induction of Sesn2 which encodes Sestrin2, a protector against oxidative and genotoxic stresses and a mTor complex 1 inhibitor. In contrast, BDNF-elevated ATF4 did not affect expression of a number of other known ATF4 targets including several with pro-apoptotic activity. The capacity of BDNF to elevate neuronal ATF4 may thus represent a means to maintain this transcription factor at levels that provide neuroprotection and optimal brain function without risk of triggering neurodegeneration. PMID- 29599708 TI - Distinct Mechanisms of Pathogenic DJ-1 Mutations in Mitochondrial Quality Control. AB - The deglycase and chaperone protein DJ-1 is pivotal for cellular oxidative stress responses and mitochondrial quality control. Mutations in PARK7, encoding DJ-1, are associated with early-onset familial Parkinson's disease and lead to pathological oxidative stress and/or disrupted protein degradation by the proteasome. The aim of this study was to gain insights into the pathogenic mechanisms of selected DJ-1 missense mutations, by characterizing protein-protein interactions, core parameters of mitochondrial function, quality control regulation via autophagy, and cellular death following dopamine accumulation. We report that the DJ-1M26I mutant influences DJ-1 interactions with SUMO-1, in turn enhancing removal of mitochondria and conferring increased cellular susceptibility to dopamine toxicity. By contrast, the DJ-1D149A mutant does not influence mitophagy, but instead impairs Ca2+ dynamics and free radical homeostasis by disrupting DJ-1 interactions with a mitochondrial accessory protein known as DJ-1-binding protein (DJBP/EFCAB6). Thus, individual DJ-1 mutations have different effects on mitochondrial function and quality control, implying mutation-specific pathomechanisms converging on impaired mitochondrial homeostasis. PMID- 29599709 TI - Caffeine and Modafinil Ameliorate the Neuroinflammation and Anxious Behavior in Rats during Sleep Deprivation by Inhibiting the Microglia Activation. AB - Background: Sleep deprivation (SD) plagues modern society due to the professional demands. It prevails in patients with mood and neuroinflammatory disorders. Although growing evidence suggests the improvement in the cognitive performance by psychostimulants during sleep-deprived conditions, the impending involved mechanism is rarely studied. Thus, we hypothesized that mood and inflammatory changes might be due to the glial cells activation induced modulation of the inflammatory cytokines during SD, which could be improved by administering psychostimulants. The present study evaluated the role of caffeine/modafinil on SD-induced behavioral and inflammatory consequences. Methods: Adult male Sprague Dawley rats were sleep deprived for 48 h using automated SD apparatus. Caffeine (60 mg/kg/day) or modafinil (100 mg/kg/day) were administered orally to rats once every day during SD. Rats were subjected to anxious and depressive behavioral evaluation after SD. Subsequently, blood and brain were collected for biochemical, immunohistochemical and molecular studies. Results: Sleep deprived rats presented an increased number of entries and time spent in closed arms in elevated plus maze test and decreased total distance traveled in the open field (OF) test. Caffeine/modafinil treatment significantly improved these anxious consequences. However, we did not observe substantial changes in immobility and anhedonia in sleep-deprived rats. Caffeine/modafinil significantly down-regulated the pro- and up-regulated the anti-inflammatory cytokine mRNA and protein expression in the hippocampus during SD. Similar outcomes were observed in blood plasma cytokine levels. Caffeine/modafinil treatment significantly decreased the microglial immunoreactivity in DG, CA1 and CA3 regions of the hippocampus during SD, however, no significant increase in immunoreactivity of astrocytes was observed. Sholl analysis signified the improvement in the morphological alterations of astrocytes and microglia after caffeine/modafinil administration during SD. Stereological analysis demonstrated a significant improvement in the number of ionized calcium binding adapter molecule I (Iba-1) positive cells (different states) in different regions of the hippocampus after caffeine or modafinil treatment during SD without showing any significant change in total microglial cell number. Eventually, the correlation analysis displayed a positive relationship between anxiety, pro-inflammatory cytokines and activated microglial cell count during SD. Conclusion: The present study suggests the role of caffeine or modafinil in the amelioration of SD-induced inflammatory response and anxious behavior in rats. Highlights - SD induced mood alterations in rats. - Glial cells activated in association with the changes in the inflammatory cytokines. - Caffeine or modafinil improved the mood and restored inflammatory changes during SD. - SD-induced anxious behavior correlated with the inflammatory consequences. PMID- 29599710 TI - Topographic Organization of Inferior Olive Projections to the Zebrin II Stripes in the Pigeon Cerebellar Uvula. AB - This study was aimed at mapping the organization of the projections from the inferior olive (IO) to the ventral uvula in pigeons. The uvula is part of the vestibulocerebellum (VbC), which is involved in the processing of optic flow resulting from self-motion. As in other areas of the cerebellum, the uvula is organized into sagittal zones, which is apparent with respect to afferent inputs, the projection patterns of Purkinje cell (PC) efferents, the response properties of PCs and the expression of molecular markers such as zebrin II (ZII). ZII is heterogeneously expressed such that there are sagittal stripes of PCs with high ZII expression (ZII+), alternating with sagittal stripes of PCs with little to no ZII expression (ZII-). We have previously demonstrated that a ZII+/- stripe pair in the uvula constitutes a functional unit, insofar as the complex spike activity (CSA) of all PCs within a ZII+/- stripe pair respond to the same type of optic flow stimuli. In the present study we sought to map the climbing fiber (CF) inputs from the IO to the ZII+ and ZII- stripes in the uvula. We injected fluorescent Cholera Toxin B (CTB) of different colors (red and green) into ZII+ and ZII- bands of functional stripe pair. Injections in the ZII+ and ZII- bands resulted in retrograde labeling of spatially separate, but adjacent regions in the IO. Thus, although a ZII+/- stripe pair represents a functional unit in the pigeon uvula, CF inputs to the ZII+ and ZII- stripes of a unit arise from separate regions of the IO.

AB - A growing body of evidence suggests the consumption of high-fat diet (HFD) during pregnancy to model maternal obesity and the associated increase in oxidative stress (OS), might act as powerful prenatal stressors, leading to adult stress related metabolic or behavioral disorders. We hypothesized that administration of antioxidants throughout gestation might counteract the negative effects of prenatal exposure to metabolic challenges (maternal HFD feeding during pregnancy) on the developing fetus. In this study, female C57BL/6J mice were fed HFD for 13 weeks (from 5-weeks of age until delivery) and were exposed to the N-acetyl cysteine (NAC) antioxidant from 10-weeks of age until right before delivery. Body weight of the offspring was assessed following birth, up to weaning and at adulthood. The metabolic, neuroendocrine and emotional profile of the adult offspring was tested at 3-months of age. Prenatal HFD increased mother's body weight and offspring's weight at the time of weaning, when administered in conjunction with NAC. In females, NAC administration reduced high levels of leptin resulting from prenatal HFD. Prenatal NAC administration also resulted in greater glucose tolerance and insulin sensitivity while increasing adiponectin levels, as well as increasing exploratory behavior, an effect accompanied by reduced plasma corticosterone levels in response to restraint stress. Analysis of glutathione levels in the hypothalamus and in brown adipose tissue indicates that, while HFD administration to pregnant dams led to reduced levels of glutathione in the offspring, as in the male hypothalamus, NAC was able to revert this effect and to increase glutathione levels both in the periphery (Brown Adipose Tissue, both males and females) and in the central nervous system (males). Overall, results from this study indicate that the body redox milieu should be tightly regulated during fetal life and that buffering OS during pregnancy can have important long-term consequences on metabolic and behavioral endpoints. PMID- 29599712 TI - Environmental Enrichment Expedites Acquisition and Improves Flexibility on a Temporal Sequencing Task in Mice. AB - Environmental enrichment (EE) via increased opportunities for voluntary exercise, sensory stimulation and social interaction, can enhance the function of and behaviours regulated by cognitive circuits. Little is known, however, as to how this intervention affects performance on complex tasks that engage multiple, definable learning and memory systems. Accordingly, we utilised the Olfactory Temporal Order Discrimination (OTOD) task which requires animals to recall and report sequence information about a series of recently encountered olfactory stimuli. This approach allowed us to compare animals raised in either enriched or standard laboratory housing conditions on a number of measures, including the acquisition of a complex discrimination task, temporal sequence recall accuracy (i.e., the ability to accurately recall a sequences of events) and acuity (i.e., the ability to resolve past events that occurred in close temporal proximity), as well as cognitive flexibility tested in the style of a rule reversal and an Intra Dimensional Shift (IDS). We found that enrichment accelerated the acquisition of the temporal order discrimination task, although neither accuracy nor acuity was affected at asymptotic performance levels. Further, while a subtle enhancement of overall performance was detected for both rule reversal and IDS versions of the task, accelerated performance recovery could only be attributed to the shift-like contingency change. These findings suggest that EE can affect specific elements of complex, multi-faceted cognitive processes.

PMID- 29599714 TI - Clustering Coefficients for Correlation Networks. AB - Graph theory is a useful tool for deciphering structural and functional networks of the brain on various spatial and temporal scales. The clustering coefficient quantifies the abundance of connected triangles in a network and is a major descriptive statistics of networks. For example, it finds an application in the assessment of small-worldness of brain networks, which is affected by attentional and cognitive conditions, age, psychiatric disorders and so forth. However, it remains unclear how the clustering coefficient should be measured in a correlation-based network, which is among major representations of brain networks. In the present article, we propose clustering coefficients tailored to correlation matrices. The key idea is to use three-way partial correlation or partial mutual information to measure the strength of the association between the two neighboring nodes of a focal node relative to the amount of pseudo correlation expected from indirect paths between the nodes. Our method avoids the difficulties of previous applications of clustering coefficient (and other) measures in defining correlational networks, i.e., thresholding on the correlation value, discarding of negative correlation values, the pseudo correlation problem and full partial correlation matrices whose estimation is computationally difficult. For proof of concept, we apply the proposed clustering coefficient measures to functional magnetic resonance imaging data obtained from healthy participants of various ages and compare them with conventional clustering coefficients. We show that the clustering coefficients decline with the age. The proposed clustering coefficients are more strongly correlated with age than the conventional ones are. We also show that the local variants of the proposed clustering coefficients (i.e., abundance of triangles around a focal node) are useful in characterizing individual nodes. In contrast, the conventional local clustering coefficients were strongly correlated with and therefore may be confounded by the node's connectivity. The proposed methods are expected to help us to understand clustering and lack thereof in correlational brain networks, such as those derived from functional time series and across participant correlation in neuroanatomical properties. PMID- 29599715 TI - DynaSim: A MATLAB Toolbox for Neural Modeling and Simulation. AB - DynaSim is an open-source MATLAB/GNU Octave toolbox for rapid prototyping of neural models and batch simulation management. It is designed to speed up and simplify the process of generating, sharing, and exploring network models of neurons with one or more compartments. Models can be specified by equations directly (similar to XPP or the Brian simulator) or by lists of predefined or custom model components. The higher-level specification supports arbitrarily complex population models and networks of interconnected populations. DynaSim also includes a large set of features that simplify exploring model dynamics over parameter spaces, running simulations in parallel using both multicore processors and high-performance computer clusters, and analyzing and plotting large numbers of simulated data sets in parallel. It also includes a graphical user interface (DynaSim GUI) that supports full functionality without requiring user programming. The software has been implemented in MATLAB to enable advanced neural modeling using MATLAB, given its popularity and a growing interest in modeling neural systems. The design of DynaSim incorporates a novel schema for model specification to facilitate future interoperability with other specifications (e.g., NeuroML, SBML), simulators (e.g., NEURON, Brian, NEST), and web-based applications (e.g., Geppetto) outside MATLAB. DynaSim is freely available at http://dynasimtoolbox.org. This tool promises to reduce barriers for investigating dynamics in large neural models, facilitate collaborative modeling, and complement other tools being developed in the neuroinformatics community. PMID- 29599717 TI - Gray Matter Network Disruptions and Regional Amyloid Beta in Cognitively Normal Adults. AB - The accumulation of amyloid plaques is one of the earliest pathological changes in Alzheimer's disease (AD) and may occur 20 years before the onset of symptoms. Examining associations between amyloid pathology and other early brain changes is critical for understanding the pathophysiological underpinnings of AD. Alterations in gray matter networks might already start at early preclinical stages of AD. In this study, we examined the regional relationship between amyloid aggregation measured with positron emission tomography (PET) and gray matter network measures in elderly subjects with subjective memory complaints. Single-subject gray matter networks were extracted from T1-weigthed structural MRI in cognitively normal subjects (n = 318, mean age 76.1 +/- 3.5, 64% female, 28% amyloid positive). Degree, clustering, path length and small world properties were computed. Global and regional amyloid load was determined using [18F] Florbetapir PET. Associations between standardized uptake value ratio (SUVr) values and network measures were examined using linear regression models. We found that higher global SUVr was associated with lower clustering (beta = -0.12, p < 0.05), and small world values (beta = -0.16, p < 0.01). Associations were most prominent in orbito- and dorsolateral frontal and parieto-occipital regions. Local SUVr values showed less anatomical variability and did not convey additional information beyond global amyloid burden. In conclusion, we found that in cognitively normal elderly subjects, increased global amyloid pathology is associated with alterations in gray matter networks that are indicative of incipient network breakdown towards AD dementia. PMID- 29599718 TI - Re-evaluation of Adrenocorticotropic Hormone and Melanocyte Stimulating Hormone Activation of GPR139 in Vitro. AB - It is now well established that GPR139, a G-protein coupled receptor exclusively expressed in the brain and pituitary, is activated by the essential amino acids L tryptophan (L-Trp) and L-phenylalanine (L-Phe) via Galphaq-coupling. The in vitro affinity and potency values of L-Trp and L-Phe are within the physiological concentration ranges of L-Trp and L-Phe. A recent paper suggests that adrenocorticotropic hormone (ACTH), alpha and beta melanocyte stimulating hormones (alpha-MSH and beta-MSH) and derivatives alpha-MSH1-9/alpha-MSH1-10 can also activate GPR139 in vitro. We tested this hypothesis using guanosine 5'-O-(3 [35S]thio)-triphosphate binding (GTPgammaS), calcium mobilization and [3H]JNJ 63533054 radioligand binding assays. In the GTPgammaS binding assay, alpha-MSH, alpha-MSH1-9/alpha-MSH1-10, and beta-MSH had no effect on [35S]GTPgammaS incorporation in cell membranes expressing GPR139 up to 30 MUM in contrast to the concentration dependent activation produced by L-Trp, JNJ-63533054, and TC-09311 (two small molecule GPR139 agonists). ACTH slightly decreased the basal level of [35S]GTPgammaS incorporation at 30 MUM. In the GPR139 radioligand binding assay, a moderate displacement of [3H]JNJ-63533054 binding by ACTH and beta-MSH was observed at 30 MUM (40 and 30%, respectively); alpha-MSH, alpha-MSH1-9/alpha-MSH1 10 did not displace any specific binding at 30 MUM. In three different host cell lines stably expressing GPR139, alpha-MSH, and beta-MSH did not stimulate calcium mobilization in contrast to L-Trp, JNJ-63533054, and TC-09311. ACTH, alpha-MSH1 9/alpha-MSH1-10 only weakly stimulated calcium mobilization at 30 MUM (<50% of EC100). We then co-transfected GPR139 with the three melanocortin (MC) receptors (MC3R, MC4R, and MC5R) to test the hypothesis that ACTH, alpha-MSH, and beta-MSH might stimulate calcium mobilization through a MCR/GPR139 interaction. All three MC peptides stimulated calcium response in cells co-transfected with GPR139 and MC3R, MC4R, or MC5R. The MC peptides did not stimulate calcium response in cells expressing MC3R or MC5R alone consistent with the Gs signaling transduction pathway of these receptors. In agreement with the previously reported multiple signaling pathways of MC4R, including Gq transduction pathway, the MC peptides produced a calcium response in cells expressing MC4R alone. Together, our findings do not support that GPR139 is activated by ACTH, alpha-MSH, and beta-MSH at physiologically relevant concentration but we did unravel an in vitro interaction between GPR139 and the MCRs. PMID- 29599716 TI - Atrophy in the Thalamus But Not Cerebellum Is Specific for C9orf72 FTD and ALS Patients - An Atlas-Based Volumetric MRI Study. AB - Background: The neuropathology of patients with frontotemporal dementia (FTD) or amyotrophic lateral sclerosis (ALS) due to a C9orf72 mutation is characterized by two distinct types of characteristic protein depositions containing either TDP-43 or so-called dipeptide repeat proteins that extend beyond frontal and temporal regions. Thalamus and cerebellum seem to be preferentially affected by the dipeptide repeat pathology unique to C9orf72 mutation carriers. Objective: This study aimed to determine if mutation carriers showed an enhanced degree of thalamic and cerebellar atrophy compared to sporadic patients or healthy controls. Methods: Atlas-based volumetry was performed in 13 affected C9orf72 FTD, ALS and FTD/ALS patients, 45 sporadic FTD and FTD/ALS patients and 19 healthy controls. Volumes and laterality indices showing significant differences between mutation carriers and sporadic patients were subjected to binary logistic regression to determine the best predictor of mutation carrier status. Results: Compared to sporadic patients, mutation carriers showed a significant volume reduction of the thalamus, which was most striking in the occipital, temporal and prefrontal subregion of the thalamus. Disease severity measured by mini mental status examination (MMSE) and FTD modified Clinical Dementia Rating Scale Sum of Boxes (FTD-CDR-SOB) significantly correlated with volume reduction in the aforementioned thalamic subregions. No significant atrophy of cerebellar regions could be detected. A logistic regression model using the volume of the prefrontal and the laterality index of the occipital subregion of the thalamus as predictor variables resulted in an area under the curve (AUC) of 0.88 while a model using overall thalamic volume still resulted in an AUC of 0.82. Conclusion: Our data show that thalamic atrophy in C9orf72 mutation carriers goes beyond the expected atrophy in the prefrontal and temporal subregion and is in good agreement with the cortical atrophy pattern described in C9orf72 mutation carriers, indicating a retrograde degeneration of functionally connected regions. Clinical relevance of the detected thalamic atrophy is illustrated by a correlation with disease severity. Furthermore, the findings suggest MRI volumetry of the thalamus to be of high predictive value in differentiating C9orf72 mutation carriers from patients with sporadic FTD. PMID- 29599720 TI - Ethnopharmacology-A Bibliometric Analysis of a Field of Research Meandering Between Medicine and Food Science? AB - Background: The research into bioactive natural products of medicinal plants has a long tradition, but ethnopharmacology as a well-defined field of research has a relatively short history, only dating back 50 years. Aims: With the fast development of this field and its global importance especially in the fast developing economies of Asia it is timely to assess the most influential articles (as measured by citations) and to identify important drivers and research trends in this field. Methods: Scopus was searched to identify relevant articles which were assessed by all three authors. The 100 most cited articles were identified and analyzed. Bibliometric software (VOSviewer) was utilized to supplement the analysis and to generate a term map that visualized the citation patterns of the 100 articles containing different terms. Results: Forty-four of the 100 articles are reviews. On average, each of the 100 articles had 632 citations and since publication was cited 43 times annually. The four core journals were Journal of Ethnopharmacology (n = 17), Food Chemistry (n = 7), Life Sciences (n = 5), and Journal of Agricultural and Food Chemistry (n = 4). Anti-oxidant effects appeared to be a recurring and highly cited topic, whereas the links into drug discovery and neuropharmacology seemed to be less strong. Numerous medicinal plants and functional foods were the foci of research, and the foci shifted when comparing pre-2000 and post-2000 publications (with the later involving a broader spectrum of plants and foods and a wider range of biological effects). Contributions largely came from Asia, and also from the Americas, Africa, and Oceania, besides Europe. Conclusion: We have identified and analyzed the 100 most-cited articles in ethnopharmacology. Within 50 years the field has gained a profile and while conventionally often linked to "traditional knowledge," drug discovery and some areas of pharmacology, this analysis highlights its emerging importance in the context of disease prevention (food science), but also the development of research driven by the needs and interests of the fast developing economies most notably of Asia. PMID- 29599705 TI - Of Men and Mice: Modeling the Fragile X Syndrome. AB - The Fragile X Syndrome (FXS) is one of the most common forms of inherited intellectual disability in all human societies. Caused by the transcriptional silencing of a single gene, the fragile x mental retardation gene FMR1, FXS is characterized by a variety of symptoms, which range from mental disabilities to autism and epilepsy. More than 20 years ago, a first animal model was described, the Fmr1 knock-out mouse. Several other models have been developed since then, including conditional knock-out mice, knock-out rats, a zebrafish and a drosophila model. Using these model systems, various targets for potential pharmaceutical treatments have been identified and many treatments have been shown to be efficient in preclinical studies. However, all attempts to turn these findings into a therapy for patients have failed thus far. In this review, I will discuss underlying difficulties and address potential alternatives for our future research. PMID- 29599719 TI - Metabotropic Glutamate2 Receptors Play a Key Role in Modulating Head Twitches Induced by a Serotonergic Hallucinogen in Mice. AB - There is substantial evidence that glutamate can modulate the effects of 5 hydroxytryptamine2A (5-HT2A) receptor activation through stimulation of metabotropic glutamate2/3 (mGlu2/3) receptors in the prefrontal cortex. Here we show that constitutive deletion of the mGlu2 gene profoundly attenuates an effect of 5-HT2A receptor activation using the mouse head twitch response (HTR). MGlu2 and mGlu3 receptor knockout (KO) as well as age-matched ICR (CD-1) wild type (WT) mice were administered (+/-)1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and observed for head twitch activity. DOI failed to produce significant head twitches in mGlu2 receptor KO mice at a dose 10-fold higher than the peak effective dose in WT or mGlu3 receptor KO mice. In addition, the mGlu2/3 receptor agonist LY379268, and the mGlu2 receptor positive allosteric modulator (PAM) CBiPES, potently blocked the HTR to DOI in WT and mGlu3 receptor KO mice. Conversely, the mGlu2/3 receptor antagonist LY341495 (10 mg/kg) increased the HTR produced by DOI (3 mg/kg) in mGlu3 receptor KO mice. Finally, the mGlu2 receptor potentiator CBiPES was able to attenuate the increase in the HTR produced by LY341495 in mGlu3 receptor KO mice. Taken together, all of these results are consistent with the hypothesis that that DOI-induced head twitches are modulated by mGlu2 receptor activation. These results also are in keeping with a critical autoreceptor function for mGlu2 receptors in the prefrontal cortex with differential effects of acute vs. chronic perturbation (e.g., constitutive mGlu2 receptor KO mice). The robust attenuation of DOI-induced head twitches in the mGlu2 receptor KO mice appears to reflect the critical role of glutamate in ongoing regulation of 5-HT2A receptors in the prefrontal cortex. Future experiments with inducible knockouts for the mGlu2 receptor and/or selective mGlu3 receptor agonists/PAMs/antagonists could provide an important tools in understanding glutamatergic modulation of prefrontal cortical 5-HT2A receptor function. PMID- 29599721 TI - The Effect of a Competitive Futsal Match on T Lymphocyte Surface Receptor Signaling and Functions. AB - In this study, the lymphocyte activation status (surface expression of CD95, CD28, CD25, and CTLA-4), lymphocyte number, lymphocyte subpopulations, lymphocyte necrosis and/or apoptosis, and lymphocyte release of reactive oxygen species (ROS) were investigated in blood samples from 16 futsal athletes before and immediately following a competitive match. Lymphocytes were isolated from the blood samples, and the cellular parameters were assessed by flow cytometry. The futsal match induced lymphocytosis and lymphocyte apoptosis, as indicated by phosphatidylserine externalization, CD95 expression, and DNA fragmentation. Additionally, the competitive match induced the necrotic death of lymphocytes. No differences in the percentage of CD4+ and CD8+ T cells or in the T helper/suppressor profile between before and immediately after the match were observed. Additionally, after the futsal match, the CD95 and CD28 expression levels were decreased, and the lymphocytes spontaneously released higher levels of ROS. Regardless of the origin, the situation-specific knowledge of lymphocyte behavior obtained herein may facilitate the design of strategies to control the processes that result in infection and tissue injury and that subsequently decrease athletic performance. PMID- 29599722 TI - Cytokine Responses to Acute Exercise in Healthy Older Adults: The Effect of Cardiorespiratory Fitness. AB - Markers of chronic inflammation increase with aging, and are associated with cardiovascular disease prevalence and mortality. Increases in fitness with exercise training have been associated with lower circulating concentrations of cytokines known to have pro-inflammatory actions (such as interleukin-6 [IL-6]) and higher circulating concentrations of anti-inflammatory cytokines (interleukin 10 [IL-10]). However, the effect of cardiorespiratory fitness on acute cytokine responses to a single bout of exercise in healthy older individuals is unknown. We compared the response of plasma cytokines IL-6, tumor necrosis factor-alpha (TNF-alpha) and IL-10 to a bout of moderate-intensity continuous and higher intensity interval exercise between older individuals with higher and lower levels of cardiorespiratory fitness. Sixteen lower-fit (VO2peak: 22.6+/-2.8 mL.kg 1.min-1) and fourteen higher-fit participants (VO2peak: 37.4+/-5.9 mL.kg-1.min-1) completed three 24 min experimental protocols in a randomized order: (1) moderate intensity continuous exercise (40% of peak power output [PPO]); (2) higher intensity interval exercise (12 * 1 min intervals at 70% PPO separated by 1 min periods at 10% PPO); or (3) non-exercise control. Plasma cytokines were measured at rest, immediately after, and during 90 min of recovery following exercise or control. Plasma IL-6 concentrations at baseline were greater in the higher-fit compared to the lower-fit group (P = 0.02), with no difference in plasma IL-10 or TNF-alpha concentrations at baseline between groups. Plasma IL-6 and IL-10 concentrations in both groups increased immediately after all protocols (IL-6: P = 0.02, IL-10: P < 0.01). However, there was no difference in the IL-6 and IL-10 response between the exercise and non-exercise (control) protocols. After all protocols, no changes in plasma TNF-alpha concentrations were observed in either the higher- or lower-fit groups. In this study, basal concentrations of circulating IL-6 were elevated in older individuals with higher levels of cardiorespiratory fitness. However, changes in plasma cytokine concentrations after exercise were not different to changes after non-exercise control in both the lower- and higher-fit groups. PMID- 29599723 TI - Brain Transcriptome Profiling Analysis of Nile Tilapia (Oreochromis niloticus) Under Long-Term Hypersaline Stress. AB - The fish brain plays an important role in controlling growth, development, reproduction, and adaptation to environmental change. However, few studies stem from the perspective of whole transcriptome change in a fish brain and its response to long-term hypersaline stress. This study compares the differential transcriptomic responses of juvenile Nile tilapia (Oreochromis niloticus) maintained for 8 weeks in brackish water (16 practical salinity units, psu) and in freshwater. Fish brains from each treatment were collected for RNA-seq analysis to identify potential genes and pathways responding to hypersaline stress. A total of 27,089 genes were annotated, and 391 genes were expressed differently in the salinity treatment. Ten pathways containing 40 differentially expressed genes were identified in the tilapia brain. Antigen processing and presentation and phagosome were the two principally affected pathways in the immune system. Thirty-one of 40 genes were involved in various expressions associated with environmental information processing pathways such as neuroactive ligand-receptor interaction, cytokine-cytokine receptor interaction, the Jak-STAT signaling pathway, cell adhesion molecules (CAMs), and the PI3K-Akt signaling pathway, which are the upstream pathways for modulation of immunity and osmoregulation. The most-changed genes (>5-fold) were all down-regulated, including four growth hormone/prolactin gene families, i.e., prolactin precursor (-10.62), prolactin-1 (-11), somatotropin (-10.15), somatolactin-like (-6.18), and two other genes [thyrotropin subunit beta (-7.73) and gonadotropin subunit beta-2 (-5.06)] that stimulated prolactin release in tilapia. The downregulation pattern of these genes corroborates the decrease in tilapia immunity with increasing salinity and reveals an adaptive mechanism of tilapia to long-term hypersaline stress. Ovarian steroidogenesis, isoquinoline alkaloid biosynthesis, and phenylalanine metabolism are the three important pathways in the response of the fish to long-term hypersaline stress. This study has identified several pathways and relevant genes that are involved in salinity regulation in a euryhaline fish and provides insight into understanding regulatory mechanisms of fish to salinity change. PMID- 29599724 TI - Age-Predicted Maximal Heart Rate in Recreational Marathon Runners: A Cross Sectional Study on Fox's and Tanaka's Equations. AB - Age-based prediction equations of maximal heart rate (HRmax), such as the popular formulas Fox's 220-age, or Tanaka's 208-0.7 * age, have been widely used in various populations. Surprisingly, so far these equations have not been validated in marathon runners, despite the importance of the role of HRmax for training purposes in endurance running. The aim of the present study was to examine the validity of Fox and Tanaka equations in a large sample of women and men recreational marathon runners. Participants (n = 180, age 43.2 +/- 8.5 years, VO2max 46.8 mL/min/kg, finishers in at least one marathon during the last year) performed a graded exercise test on a treadmill, where HRmax was measured. Measured HRmax correlated largely with age in the total sample (r = -0.50, p < 0.001), women (r = -0.60, p < 0.001) and men (r = -0.53, p < 0.001). In women, a large main effect of method on HRmax (p = 0.001, eta2 = 0.294) was shown with measured HRmax lower than Fox-HRmax (-4.8 bpm; -8.4, -1.3) and Tanaka-HRmax (-4.9 bpm; -8.1, -1.8). In men, a moderate effect of assessment method on HRmax was found (p = 0.001, eta2 = 0.066) with measured HRmax higher than Fox-HRmax (+2.8; 1.0, 4.6), Tanaka-HRmax higher than Fox-HRmax (+1.2; 0.7, 1.7). Based on these findings, it was concluded that Fox and Tanaka' formulas overestimated HRmax by ~5 bpm in women, whereas Fox underestimated HRmax in men by ~3 bpm. Thus, we recommend the further use of Tanaka's formula in men marathon runners. In addition, exercise physiologists and sport scientists should consider the observed differences among various assessment methods when performing exercise testing or prescribing training program relying on HR. PMID- 29599725 TI - Validity and Reliability of 10-Hz Global Positioning System to Assess In-line Movement and Change of Direction. AB - The objectives of the present study were to examine the validity and reliability of the 10 Hz Johan GPS unit in assessing in-line movement and change of direction. The validity was tested against the criterion measure of 200 m track and-field (track-and-field athletes, n = 8) and 20 m shuttle run endurance test (female soccer players, n = 20). Intra-unit and inter-unit reliability was tested by intra-class correlation coefficient (ICC) and coefficient of variation (CV), respectively. An analysis of variance examined differences between the GPS measurement and five laps of 200 m at 15 km/h, and t-test examined differences between the GPS measurement and 20 m shuttle run endurance test. The difference between the GPS measurement and 200 m distance ranged from -0.13 +/- 3.94 m (95% CI -3.42; 3.17) in the first lap to 2.13 +/- 2.64 m (95% CI -0.08; 4.33) in the fifth lap. A good intra-unit reliability was observed in 200 m (ICC = 0.833, 95% CI 0.535; 0.962). Inter-unit CV ranged from 1.31% (fifth lap) to 2.20% (third lap). The difference between the GPS measurement and 20 m shuttle run endurance test ranged from 0.33 +/- 4.16 m (95% CI -10.01; 10.68) in 11.5 km/h to 9.00 +/- 5.30 m (95% CI 6.44; 11.56) in 8.0 km/h. A moderate intra-unit reliability was shown in the second and third stage of the 20 m shuttle run endurance test (ICC = 0.718, 95% CI 0.222;0.898) and good reliability in the fifth, sixth, seventh and eighth (ICC = 0.831, 95% CI -0.229;0.996). Inter-unit CV ranged from 2.08% (11.5 km/h) to 3.92% (8.5 km/h). Based on these findings, it was concluded that the 10 Hz Johan system offers an affordable valid and reliable tool for coaches and fitness trainers to monitor training and performance. PMID- 29599726 TI - The Neural Correlates of Probabilistic Classification Learning in Obsessive Compulsive Disorder: A Pilot Study. AB - Individuals suffering from obsessive-compulsive disorder (OCD) have been found to show deficits in implicitly learning probabilistic associations between events. Neuroimaging studies have associated these implicit learning deficits in OCD individuals with aberrant activation of the striatal system. Recent behavioral studies have highlighted that probabilistic classification learning (PCL) deficits in OCD individuals only occur in a disorder-specific context, while PCL remains intact in a neutral context. The neural correlates of implicit learning in an OCD-specific context, however, have not yet been investigated. Using functional magnetic resonance imaging during a neutral (prediction of weather) and an OCD-specific variant (prediction of a virus epidemic) of a PCL paradigm, we assessed brain activity associated with implicit learning processes in 10 participants with OCD and 10 matched healthy controls. Regions of interest (ROIs) were the striatum and the medial temporal lobe. ROI analyses revealed a significantly higher activity in the bilateral putamen and the left hippocampus of OCD participants as compared to healthy controls during both PCL tasks. The group differences could partly be subsumed under a group * task interaction effect with OCD participants showing a significantly higher activity than healthy controls in the left putamen and the left hippocampus in the OCD-specific task variant only. These results suggest a compensation of aberrant striatal activity by an augmented engagement of the explicit memory system particularly in a disorder-relevant context in OCD participants. PMID- 29599727 TI - Brain GABA and Glutamate Concentrations Following Chronic Gabapentin Administration: A Convenience Sample Studied During Early Abstinence From Alcohol. AB - Gabapentin (GBP), a GABA analog that may also affect glutamate (Glu) production, can normalize GABA and Glu tone during early abstinence from alcohol, effectively treating withdrawal symptoms and facilitating recovery. Using in vivo magnetic resonance spectroscopy, we tested the degree to which daily GBP alters regional brain GABA and Glu levels in short-term abstinent alcohol-dependent individuals. Regional metabolite levels were compared between 13 recently abstinent alcohol dependent individuals who had received daily GBP for at least 1 week (GBP+) and 25 matched alcohol-dependent individuals who had not received GBP (GBP-). Magnetic resonance spectra from up to five different brain regions were analyzed to yield absolute GABA and Glu concentrations. GABA and Glu concentrations in the parieto-occipital cortex were not different between GBP- and GBP+. Glu levels in anterior cingulate cortex, dorsolateral prefrontal cortex, and basal ganglia did not differ between GBP- and GBP+. However, in a subgroup of individuals matched on age, sex, and abstinence duration, GBP+ had markedly lower Glu in the frontal white matter (WM) than GBP-, comparable to concentrations found in light/non drinking controls. Furthermore, lower frontal WM Glu in GBP+ correlated with a higher daily GBP dose. Daily GBP treatment at an average of 1,600 mg/day for at least 1 week was not associated with altered cortical GABA and Glu concentrations during short-term abstinence from alcohol, but with lower Glu in frontal WM. GBP for the treatment of alcohol dependence may work through reducing Glu in WM rather than increasing cortical GABA. PMID- 29599728 TI - Altered Resting State Effective Connectivity of Anterior Insula in Depression. AB - Depression has been associated with changes in both functional and effective connectivity of large scale brain networks, including the default mode network, executive network, and salience network. However, studies of effective connectivity by means of spectral dynamic causal modeling (spDCM) are still rare and the interaction between the different resting state networks has not been investigated in detail. Thus, we aimed at exploring differences in effective connectivity among eight right hemisphere brain areas-anterior insula, inferior frontal gyrus, middle frontal gyrus (MFG), frontal eye field, anterior cingulate cortex, superior parietal lobe, amygdala, and hippocampus, between a group of healthy controls (N = 20) and medicated depressed patients (N = 20). We found that patients not only had significantly reduced strength of the connection from the anterior insula to the MFG (i.e., dorsolateral prefrontal cortex) but also a significant connection between the amygdala and the anterior insula. Moreover, depression severity correlated with connectivity of the hippocampal node. In conclusion, the results from this resting state spDCM study support and enrich previous data on the role of the right anterior insula in the pathophysiology of depression. Furthermore, our findings add to the growing evidence of an association between depression severity and disturbances of the hippocampal function in terms of impaired connectivity with other brain regions. PMID- 29599729 TI - Efficacy of the Aussie Optimism Program: Promoting Pro-social Behavior and Preventing Suicidality in Primary School Students. A Randomised-Controlled Trial. AB - The efficacy of an enhanced version of the Aussie Optimism Program (AOP) was investigated in a cluster randomized controlled trial. Grade 6 students aged 10 11 years of age (N = 2288) from 63 government primary schools in Perth, Western Australia, participated in the pre, post, and follow-up study. Schools were randomly assigned to one of three conditions: Aussie Optimism with teacher training, Aussie Optimism with teacher training plus coaching, or a usual care condition that received the regular Western Australian Health Education Curriculum. Students in the Aussie Optimism conditions received 20, 1-h lessons relating to social and interpersonal skills and optimistic thinking skills over the last 2 years of primary school. Parents in the active conditions received a parent information booklet each year, plus a self-directed program in Grade 7. Students and parents completed the Extended Strengths and Difficulties Questionnaire. Students who scored in the clinical range on the Emotional Symptoms Scale were given The Diagnostic Interview for Children and Adolescents IV, to assess suicidal ideation and behavior, and depressive and anxiety disorders. Results indicated that Aussie Optimism with teacher training plus coaching was associated with the best outcomes: a significant increase in student reported pro-social behavior from pre-test to post-test 1 (maintained at post test 2) and significantly lower incidence rates from suicidal ideation at post test 2 and follow-up. No significant intervention effects on anxiety and depressive disorders, and total difficulties were reported. These findings suggest that the AOP with teacher training along with coaching may have the potential to positively impact on suicidality and pro-social behavior in the pre adolescent years. PMID- 29599730 TI - Monolingual and Bilingual Infants' Ability to Use Non-native Tone for Word Learning Deteriorates by the Second Year After Birth. AB - Previous studies reported a non-native word learning advantage for bilingual infants at around 18 months. We investigated developmental changes in infant interpretation of sounds that aid in object mapping. Dutch monolingual and bilingual (exposed to Dutch and a second non-tone-language) infants' word learning ability was examined on two novel label-object pairings using syllables differing in Mandarin tones as labels (flat vs. falling). Infants aged 14-15 months, regardless of language backgrounds, were sensitive to violations in the label-objects pairings when lexical tones were switched compared to when they were the same as habituated. Conversely at 17-18 months, neither monolingual nor bilingual infants demonstrated learning. Linking with existing literature, infants' ability to associate non-native tones with meanings may be related to tonal acoustic properties and/or perceptual assimilation to native prosodic categories. These findings provide new insights into the relation between infant tone perception, learning, and interpretative narrowing from a developmental perspective. PMID- 29599731 TI - Top-Down Prioritization of Salient Items May Produce the So-Called Stimulus Driven Capture. AB - The current study proposes that top-down attentional prioritization of salient items may produce the so-called stimulus-driven capture. To test this proposal, the "expectation-based paradigm" was designed on the basis of a visual search task. In Experiment 1, a task-irrelevant singleton frame was presented at the same location in 70% of the trials. The target was either presented at chance level within the singleton location, or away from it. In line with the singleton capture phenomenon, participants were faster in identifying the target when it appeared in the singleton location compared to non-singleton locations. However, leaving out the singleton frame in 30% of the trials led to a similar effect; participants were faster in identifying the target when it appeared in the expected singleton location compared to expected non-singletons locations (a "quasi-capture" effect). These results suggest that the participants allocated their attention to the expected singleton location, rather than that the singleton itself captured attention. In Experiment 2, the same task-irrelevant color singleton was presented in a random position in 70% of the trials. This color frame was shown as a non-singleton in all of the 30% singleton-absent multicolored trials. A similar facilitation effect was obtained when the target appeared in the expected singleton color frame compared to other frames, in singleton-absent trials as in singleton-present trials. These results further support the idea that instances of singleton capture can be explained by top-down attentional shifts toward singleton items. Theoretical implications of these results are discussed. Mostly, the study calls to consider the possibility that all sources of attentional control may be represented by a continuous variable of top-down control, including the category of "physical salience." PMID- 29599732 TI - Functions of Autobiographical Memory in Younger and Older Adults. AB - Functional approach to autobiographical memory (AM) posits its three broad functions: directive, self, and social. Although these functions are probably universal, life stage and gender variations are expected. This research builds on previous studies investigating the validity of Thinking About Life Experiences Questionnaire (TALE; Bluck and Alea, 2011). A sample of 365 adults (56% female, mean age 43.3 years), divided in 2 age cohorts (young: 18-45 years, old: 46-90 years), used TALE, to rate their tendency of using AM for three different purposes, and measures of self-concept clarity, attachment in close relationships and time perspective. Confirmatory factor analysis of TALE confirmed the tripartite model of AM functions and further analysis showed partial factorial equivalence across age and gender groups. Young tend to use AM more for directing future behavior and social-bonding, while no age differences were found in the use of AM to serve self-function. As for gender variations, women tend to use AM more for directing their behavior, while no other gender differences in the use of AM were found. TALE showed good internal consistency and convergent validity of the three subscales. The theory-driven hypotheses that individuals with low self-concept clarity would use AM more often to serve a self-function, those with higher levels of attachment anxiety would use AM more often to serve a social function, and those past-oriented would use memory more often for directive purpose, were all confirmed. Also confirmed was the notion of Past Negative Orientation to be more related to the directive use of AM than Past Positive Time Orientation. Limitations and future directions are discussed. PMID- 29599733 TI - L2-L1 Translation Priming Effects in a Lexical Decision Task: Evidence From Low Proficient Korean-English Bilinguals. AB - One of the key issues in bilingual lexical representation is whether L1 processing is facilitated by L2 words. In this study, we conducted two experiments using the masked priming paradigm to examine how L2-L1 translation priming effects emerge when unbalanced, low proficiency, Korean-English bilinguals performed a lexical decision task. In Experiment 1, we used a 150 ms SOA (50 ms prime duration followed by a blank interval of 100 ms) and found a significant L2-L1 translation priming effect. In contrast, in Experiment 2, we used a 60 ms SOA (50 ms prime duration followed by a blank interval of 10 ms) and found a null effect of L2-L1 translation priming. This finding is the first demonstration of a significant L2-L1 translation priming effect with unbalanced Korean-English bilinguals. Implications of this work are discussed with regard to bilingual word recognition models. PMID- 29599734 TI - Using Shakespeare's Sotto Voce to Determine True Identity From Text. AB - Little is known of the private life of William Shakespeare, but he is famous for his collection of plays and poems, even though many of the works attributed to him were published anonymously. Determining the identity of Shakespeare has fascinated scholars for 400 years, and four significant figures in English literary history have been suggested as likely alternatives to Shakespeare for some disputed works: Bacon, de Vere, Stanley, and Marlowe. A myriad of computational and statistical tools and techniques have been used to determine the true authorship of his works. Many of these techniques rely on basic statistical correlations, word counts, collocated word groups, or keyword density, but no one method has been decided on. We suggest that an alternative technique that uses word semantics to draw on personality can provide an accurate profile of a person. To test this claim, we analyse the works of Shakespeare, Christopher Marlowe, and Elizabeth Cary. We use Word Accumulation Curves, Hierarchical Clustering overlays, Principal Component Analysis, and Linear Discriminant Analysis techniques in combination with RPAS, a multi-faceted text analysis approach that draws on a writer's personality, or self to identify subtle characteristics within a person's writing style. Here we find that RPAS can separate the known authored works of Shakespeare from Marlowe and Cary. Further, it separates their contested works, works suspected of being written by others. While few authorship identification techniques identify self from the way a person writes, we demonstrate that these stylistic characteristics are as applicable 400 years ago as they are today and have the potential to be used within cyberspace for law enforcement purposes. PMID- 29599735 TI - On the Determinants and Outcomes of Passion for Playing Pokemon Go. AB - In 2016, Pokemon Go became the most popular smartphone game. Despite the increasing popularity of this augmented reality game, to date, no studies have investigated passion for playing Pokemon Go. On the theoretical basis of the Dualistic Model of Passion (DMP), our goal was to investigate the associations between Pokemon Go playing motives, passion, and impulsivity. A total of 621 Pokemon Go players participated in the study (54.9% female; Mage = 22.6 years, SDage = 4.4). It was found that impulsivity was more strongly associated with obsessive passion (OP) than with harmonious passion (HP). HP was associated with adaptive motives (i.e., outdoor activity, social, recreation, and nostalgia), while OP was associated with less adaptive motives (i.e., fantasy, escape, boredom, competition, and coping). Therefore, in line with the DMP, HP and OP for playing Pokemon Go can predict an almost perfectly distinguished set of adaptive or maladaptive playing motives, and OP has a noteworthy relationship with impulsivity as a determinant. PMID- 29599736 TI - TIMSS 2011 Student and Teacher Predictors for Mathematics Achievement Explored and Identified via Elastic Net. AB - A substantial body of research has been conducted on variables relating to students' mathematics achievement with TIMSS. However, most studies have employed conventional statistical methods, and have focused on selected few indicators instead of utilizing hundreds of variables TIMSS provides. This study aimed to find a prediction model for students' mathematics achievement using as many TIMSS student and teacher variables as possible. Elastic net, the selected machine learning technique in this study, takes advantage of both LASSO and ridge in terms of variable selection and multicollinearity, respectively. A logistic regression model was also employed to predict TIMSS 2011 Korean 4th graders' mathematics achievement. Ten-fold cross-validation with mean squared error was employed to determine the elastic net regularization parameter. Among 162 TIMSS variables explored, 12 student and 5 teacher variables were selected in the elastic net model, and the prediction accuracy, sensitivity, and specificity were 76.06, 70.23, and 80.34%, respectively. This study showed that the elastic net method can be successfully applied to educational large-scale data by selecting a subset of variables with reasonable prediction accuracy and finding new variables to predict students' mathematics achievement. Newly found variables via machine learning can shed light on the existing theories from a totally different perspective, which in turn propagates creation of a new theory or complement of existing ones. This study also examined the current scale development convention from a machine learning perspective. PMID- 29599737 TI - Development of the Sexual Minority Adolescent Stress Inventory. AB - Although construct measurement is critical to explanatory research and intervention efforts, rigorous measure development remains a notable challenge. For example, though the primary theoretical model for understanding health disparities among sexual minority (e.g., lesbian, gay, bisexual) adolescents is minority stress theory, nearly all published studies of this population rely on minority stress measures with poor psychometric properties and development procedures. In response, we developed the Sexual Minority Adolescent Stress Inventory (SMASI) with N = 346 diverse adolescents ages 14-17, using a comprehensive approach to de novo measure development designed to produce a measure with desirable psychometric properties. After exploratory factor analysis on 102 candidate items informed by a modified Delphi process, we applied item response theory techniques to the remaining 72 items. Discrimination and difficulty parameters and item characteristic curves were estimated overall, within each of 12 initially derived factors, and across demographic subgroups. Two items were removed for excessive discrimination and three were removed following reliability analysis. The measure demonstrated configural and scalar invariance for gender and age; a three-item factor was excluded for demonstrating substantial differences by sexual identity and race/ethnicity. The final 64-item measure comprised 11 subscales and demonstrated excellent overall (alpha = 0.98), subscale (alpha range 0.75-0.96), and test-retest (scale r > 0.99; subscale r range 0.89-0.99) reliabilities. Subscales represented a mix of proximal and distal stressors, including domains of internalized homonegativity, identity management, intersectionality, and negative expectancies (proximal) and social marginalization, family rejection, homonegative climate, homonegative communication, negative disclosure experiences, religion, and work domains (distal). Thus, the SMASI development process illustrates a method to incorporate information from multiple sources, including item response theory models, to guide item selection in building a psychometrically sound measure. We posit that similar methods can be used to improve construct measurement across all areas of psychological research, particularly in areas where a strong theoretical framework exists but existing measures are limited. PMID- 29599738 TI - Peer Learning in Instrumental Practicing. AB - In higher music education (HME), the notion of "private teaching, private learning" has a long tradition, where the learning part rests on the student's individual practicing between instrumental lessons. However, recent research suggests that collaborative learning among peers is beneficial in several aspects, such as sense of belonging, motivation and self-efficacy. This is consistent with the concept of vicarious learning. In this study, we conducted a survey among bachelor music students in church music, performance or music education programs enrolled in a music academy (N = 96), where parts of the questionnaire addressed peer learning and peer's influence on the students's instrumental practicing, and the degree of satisfaction with their practicing. These issues were seen in relation to gender, musical genre and study program. Overall, the students reported engaging in peer learning related to their instrumental practicing, to various degrees. This involved discussing practicing matters with peers, and practicing together with peers. However, student's reports of their views on peer learning, show that they perceive it more beneficial than the amount of time reported doing it would indicate. No significant gender differences were found, but students within improvised music/jazz engaged the most in peer learning, and church music students the least. Neither the degree of engaging in peer learning nor reported influence from peers correlated significantly with the degree of satisfaction. We discuss whether a general dissatisfaction is caused by being in a competitive learning environment combined with a privatized culture for learning. Finally, we suggest that collaborative forums for instrumental practicing within HME institutions can function as constructive and supportive arenas to enhance students learning and inner motivation. PMID- 29599739 TI - Illusory Motion Reproduced by Deep Neural Networks Trained for Prediction. AB - The cerebral cortex predicts visual motion to adapt human behavior to surrounding objects moving in real time. Although the underlying mechanisms are still unknown, predictive coding is one of the leading theories. Predictive coding assumes that the brain's internal models (which are acquired through learning) predict the visual world at all times and that errors between the prediction and the actual sensory input further refine the internal models. In the past year, deep neural networks based on predictive coding were reported for a video prediction machine called PredNet. If the theory substantially reproduces the visual information processing of the cerebral cortex, then PredNet can be expected to represent the human visual perception of motion. In this study, PredNet was trained with natural scene videos of the self-motion of the viewer, and the motion prediction ability of the obtained computer model was verified using unlearned videos. We found that the computer model accurately predicted the magnitude and direction of motion of a rotating propeller in unlearned videos. Surprisingly, it also represented the rotational motion for illusion images that were not moving physically, much like human visual perception. While the trained network accurately reproduced the direction of illusory rotation, it did not detect motion components in negative control pictures wherein people do not perceive illusory motion. This research supports the exciting idea that the mechanism assumed by the predictive coding theory is one of basis of motion illusion generation. Using sensory illusions as indicators of human perception, deep neural networks are expected to contribute significantly to the development of brain research. PMID- 29599740 TI - The Role of Emotion Regulation in Reducing Emotional Distortions of Duration Perception. AB - Emotional events, especially negative ones, are consistently reported to last longer than neutral events. Previous studies suggested that this distortion of duration perception is linked to arousal and attention bias in response to emotional events. Reappraisal and suppression, arguably the most effective strategies for emotion regulation, have been demonstrated to decrease such arousal and attention bias. The present study investigated whether reappraisal and suppression can reduce emotional distortions of duration perception. Seventy eight Chinese undergraduates were recruited as paid participants and randomly assigned to nonregulation, reappraisal, and suppression groups. Before they performed a temporal bisection task involving presentation of emotional pictures for different durations, the groups were each given one of three different sets of instructions requiring them to passively perceive, reappraise, or suppress the emotions of the pictures. The results indicated that the distortion of duration perception occurred only in the nonregulation group, suggesting that it can be effectively reduced by reappraisal and suppression. PMID- 29599741 TI - The Quest for an Alzheimer Therapy. AB - This mini-review considers three different approaches to the therapy and prevention of Alzheimer's disease (AD): replacement therapy, disease modification, and multi-level interventions. Each of these research frameworks has direct implications at the clinical level, leading to an emphasis on different time points of the AD continuum. While all perspectives continue to play an important role in current efforts to reach the ambitious target of an effective therapy or prevention of AD by 2025, it is clear that novel paradigms are needed, including new models of clinical trial design. This goal can only be accomplished by a concerted effort of academia, governmental agencies, and industry. PMID- 29599742 TI - The Video Head Impulse Test and the Influence of Daily Use of Spectacles to Correct a Refractive Error. AB - Objective: To determine the influence of daily use of spectacles to correct a refractive error, on the vestibulo-ocular reflex (VOR) gain measured with the video head impulse test (vHIT). Study design: This prospective study enrolled subjects between 18 and 80 years old with and without a refractive error. Subjects were classified into three groups: (1) contact lenses, (2) spectacles, and (3) control group without visual impairment. Exclusion criteria comprised ophthalmic pathology, history of vestibular disorders, and alternated use of spectacles and contact lenses in daily life. Corrective spectacles were removed seconds before testing. One examiner performed all vHIT's under standardized circumstances using the EyeSeeCam system. This system calculated the horizontal VOR gain for rightward and leftward head rotations separately. Results: No statistically significant difference was found in VOR gain between the control group (n = 16), spectacles group (n = 48), and contact lenses group (n = 15) (p = 0.111). Both the spectacles group and contact lenses group showed no statistically significant correlation between VOR gain and amount of refractive error, for rightwards (p = 0.071) and leftwards (p = 0.716) head rotations. There was no statistical significant difference in VOR gain between testing monocularly or binocularly (p = 0.132) and between testing with or without wearing contact lenses (p = 0.800). Conclusion: In this study, VOR gain was not influenced by wearing corrective spectacles or contact lenses on a daily basis. Based on this study, no corrective measures are necessary when performing the vHIT on subjects with a refractive error, regardless of the way of correction. PMID- 29599743 TI - A Tool to Quantify the Functional Impact of Oscillopsia. AB - Background: Individuals with bilateral vestibular hypofunction (BVH) often report symptoms of oscillopsia during walking. Existing assessments of oscillopsia are limited to descriptions of severity and symptom frequency, neither of which provides a description of functional limitations attributed to oscillopsia. A novel questionnaire, the Oscillopsia Functional Impact scale (OFI) was developed to describe the impact of oscillopsia on daily life activities. Questions on the OFI ask how often individuals are able to execute specific activities considered to depend on gaze stability in an effort to link functional mobility impairments to oscillopsia for individuals with vestibular loss. Methods: Subjective reports of oscillopsia and balance confidence were recorded for 21 individuals with BVH and 48 healthy controls. Spearman correlation coefficients were calculated to determine the relationship between the OFI and oscillopsia visual analog scale (OS VAS), oscillopsia severity questionnaire (OSQ), and Activities-Specific Balance Confidence scale to demonstrate face validity. Chronbach's alpha was calculated to determine internal validity for the items of the OFI. A one-way MANOVA was conducted with planned post hoc paired t-tests for group differences on all oscillopsia questionnaires using a corrected alpha = 0.0125. Results: The OFI was highly correlated with measures of oscillopsia severity (OS VAS; r = 0.69, p < 0.001) and frequency (OSQ; r = 0.84, p < 0.001) and also with the Activities-Specific Balance Confidence scale (r = -0.84, p < 0.001). Cronbach's alpha for the OFI was 0.97. Individuals with BVH scored worse on all measures of oscillopsia and balance confidence compared to healthy individuals (p's < 0.001). Conclusion: The OFI appears to capture the construct of oscillopsia in the context of functional mobility. Combining with oscillopsia metrics that quantify severity and frequency allows for a more complete characterization of the impact of oscillopsia on an individual's daily behavior. The OFI discriminated individuals with BVH from healthy individuals. PMID- 29599744 TI - Myopathy With SQSTM1 and TIA1 Variants: Clinical and Pathological Features. AB - Objective: The aim of this study is to identify the molecular defect of three unrelated individuals with late-onset predominant distal myopathy; to describe the spectrum of phenotype resulting from the contributing role of two variants in genes located on two different chromosomes; and to highlight the underappreciated complex forms of genetic myopathies. Patients and methods: Clinical and laboratory data of three unrelated probands with predominantly distal weakness manifesting in the sixth-seventh decade of life, and available affected and unaffected family members were reviewed. Next-generation sequencing panel, whole exome sequencing, and targeted analyses of family members were performed to elucidate the genetic etiology of the myopathy. Results: Genetic analyses detected two contributing variants located on different chromosomes in three unrelated probands: a heterozygous pathogenic mutation in SQSTM1 (c.1175C>T, p.Pro392Leu) and a heterozygous variant in TIA1 (c.1070A>G, p.Asn357Ser). The affected fraternal twin of one proband also carries both variants, while the unaffected family members harbor one or none. Two unrelated probands (family 1, II.3, and family 3, II.1) have a distal myopathy with rimmed vacuoles that manifested with index extensor weakness; the other proband (family 2, I.1) has myofibrillar myopathy manifesting with hypercapnic respiratory insufficiency and distal weakness. Conclusion: The findings indicate that all the affected individuals have a myopathy associated with both variants in SQSTM1 and TIA1, respectively, suggesting that the two variants determine the phenotype and likely functionally interact. We speculate that the TIA1 variant is a modifier of the SQSTM1 mutation. We identify the combination of SQSTM1 and TIA1 variants as a novel genetic defect associated with myofibrillar myopathy and suggest to consider sequencing both genes in the molecular investigation of myopathy with rimmed vacuoles and myofibrillar myopathy although additional studies are needed to investigate the digenic nature of the disease. PMID- 29599745 TI - Treatment Modality and Quality Benchmarks of Aneurysmal Subarachnoid Hemorrhage at a Comprehensive Stroke Center. AB - Background: Aneurysmal subarachnoid hemorrhage (aSAH) is the most severe type of stroke. In 2012, the Joint Commission, in collaboration with the American Heart Association/American Stroke Association (AHA/ASA), launched the Advanced Certification for Comprehensive Stroke Centers (CSCs). This new level of certification was designed to promote higher standard of care for patients with complex stroke. Objective: The goal of this study was to examine the treatment modality and quality benchmarks of aSAH at one of the first five certified CSCs in the United States. Methods: Consecutive patients with aSAH at Cedars-Sinai Medical Center between April 1, 2012 and May 30, 2014 were included for this retrospective study. The ruptured aneurysm was treated with coiling or clipping within 24 h. All patients were managed per AHA guidelines. Discharge outcomes were assessed using modified Rankin Scale (mRS). The rate of aneurysm treatment, door-to-treatment time, rate of posttreatment rebleed, hospital length of stay (LOS), discharge outcome, and mortality rates were evaluated as quality indicators. Results: The median age (interquartile range) of the 118 patients with aSAH was 55 (19). Among them, 84 (71.2%) were females, 94 (79.7%) were transfers from outside hospitals, and 74 (62.7%) had Hunt and Hess grades 1-3. Sixty patients (50.8%) were treated with coiling, 52 (44.1%) with clipping, and 6 (5.1%) untreated due to ictal cardiac arrest or severe comorbidities. The rate of aneurysm treatment was 95% (112/118) with median door-to-treatment time at 12.5 (8.5) h and 0.9% (1/112) posttreatment rebleed. The median ICU and hospital LOS were 12.5 (7) and 17.0 (14.5) days, respectively. Coiling was associated with significantly shorter LOS than clipping. There were 59 patients (50%) with favorable outcome and 19 deaths (16.1%) at hospital discharge. There was no significant difference in discharge outcome between coiling and clipping. Conclusion: Care of aSAH at one of the early CSCs in the United States was associated with high rate of aneurysm treatment, fast door-to-treatment time, low posttreatment rebleed, excellent outcome, and low mortality rate. Coiling was associated with significant shorter LOS than clipping. There was no significant difference in discharge outcomes between treatment modalities. PMID- 29599746 TI - Peripheral Dopamine in Restless Legs Syndrome. AB - Objective/Background: Restless Legs Syndrome (RLS) is a dopamine-dependent disorder characterized by a strong urge to move. The objective of this study was to evalulate blood levels of dopamine and other catecholamines and blood D2 subtype dopamine receptors (D2Rs) in RLS. Patients/Methods: Dopamine levels in blood samples from age-matched unmedicated RLS subjects, medicated RLS subjects and Controls were evaluated with high performance liquid chromatography and dopamine D2R white blood cell (WBC) expression levels were determined with fluorescence-activated cell sorting and immunocytochemistry. Results: Blood plasma dopamine levels, but not norepinepherine or epinephrine levels, were significantly increased in medicated RLS subjects vs unmedicated RLS subjects and Controls. The percentage of lymphocytes and monocytes expressing D2Rs differed between Control, RLS medicated and RLS unmedicated subjects. Total D2R expression in lymphocytes, but not monocytes, differed between Control, RLS medicated and RLS unmedicated subjects. D2Rs in lymphocytes, but not monocytes, were sensitive to dopamine in Controls only. Conclusion: Downregulation of WBCs D2Rs occurs in RLS. This downregulation is not reversed by medication, although commonly used RLS medications increase plasma dopamine levels. The insensitivity of monocytes to dopamine levels, but their downregulation in RLS, may reflect their utility as a biomarker for RLS and perhaps brain dopamine homeostasis. PMID- 29599747 TI - Circadian and Metabolic Perspectives in the Role Played by NADPH in Cancer. AB - Physiological activity in healthy conditions requires a coordinated interaction between the molecular circadian clock and the network of biochemical pathways. An important metabolic parameter in the interface between these two entities is the redox state. Among the redox coenzymes that regulate the fluxes of enzymatic reactions is the NADP+/NADPH pair. Indeed, the main biosynthetic pathways need NADPH to serve as an electron donor for cellular anabolic transformations. The existence of a metabolic circadian clock is well established, and it was first identified in mammalian red blood cells. The metabolic circadian clock is independent of transcriptional activity and is sustained by the enzymatic complex peroxiredoxin/thioredoxin/NADPH. This complex shows 24-h redox fluctuations metabolizing H2O2 in various tissues and species (fungi, insects, and mammals). Although this NADPH-sensitive metabolic clock is autonomous in erythrocytes that lack a nucleus, it functions in concert with the transcriptional circadian clock in other cell types to accomplish the task of timing cellular physiology. During carcinogenesis, circadian alterations influence cell cycle onset and promote tumoral growth. These alterations also deregulate cellular energetics through a process known as aerobic glycolysis, or the Warburg effect. The Warburg effect is a typical response of cancer cells in which the metabolism turns into glycolysis even in the presence of functional mitochondria. This alteration has been interpreted as a cellular strategy to increase biomass during cancer, and one of its main factors is the availability of NADPH. This minireview explores the potential role of NADPH as a circadian and cancer-promoting metabolite. PMID- 29599748 TI - Polyostotic Fibrous Dysplasia With and Without McCune-Albright Syndrome-Clinical Features in a Nordic Pediatric Cohort. AB - Objective: Fibrous dysplasia (FD) presents as skeletal lesions in which normal bone is replaced by abnormal fibrous tissue due to mosaic GNAS mutation. McCune Albright syndrome (MAS) refers to FD combined with skin (cafe-au-lait) and endocrine manifestations. This study describes the clinical childhood manifestations of polyostotic FD and MAS in a Nordic cohort. Patients and design: We retrospectively reviewed a cohort of pediatric patients (n = 16) with polyostotic FD with or without MAS diagnosed and followed in two Nordic Pediatric tertiary clinics between 1996 and 2017. Results: Half of the 16 patients with polyostotic FD presented with MAS. All patients with MAS (n = 8) had cafe-au-lait spots, and either gonadotropin-independent precocious puberty (PP) (girls; n = 5) or abnormal testicle structure (boys, n = 3). None manifested hyperthyroidism or growth hormone excess. Mild hypophosphatemia was common (11/16), but none had signs of hypophosphatemic rickets. Craniofacial bone involvement was found in 12 patients (75%); in 5 of these, skeletal lesions were limited to craniofacial area. One child with craniofacial disease had lost vision due to optic nerve damage. Eleven (69%) patients had sustained a fracture at FD lesion, over half of them requiring surgical fixation of the fracture, most commonly in the proximal femur. The first symptoms leading to FD/MAS diagnosis included skull/facial asymmetry (n = 4), PP (n = 3), abnormal gait (n = 3), pathologic fracture (n = 3), wide-spread cafe-au-lait spots (n = 1), headache (n = 1), and vision loss (n = 1). Conclusion: Polyostotic FD and MAS remain diagnostic and therapeutic challenges because of the broad clinical spectrum. Recurrent fractures, pain, and even vision loss may impair the quality of life in children with FD. PMID- 29599749 TI - miR-518b Enhances Human Trophoblast Cell Proliferation Through Targeting Rap1b and Activating Ras-MAPK Signal. AB - Preeclampsia is a pregnancy-specific complication defined as newly onset gestational hypertension and proteinuria. Deficiency in placental development is considered as the predominant cause of preeclampsia. Our previous study found that the expression of miR-518b increased significantly in the preeclamptic placentas, indicating the potential participation of this small RNA in the occurrence of preeclampsia. In this study, data analysis using multiple databases predicted Rap1b as a candidate target of miR-518b. An evident decrease in Rap1b expression was observed in preeclamptic placentas when compared with the control placentas, which was negatively correlated with the level of miR-518b. Based on the data of in situ hybridization and immunohistochemistry showing that Rap1b exhibited similar localization with miR-518b in villous cytotrophoblast cells and column trophoblasts, we further explored their function in regulating trophoblast cell proliferation. In HTR8/SVneo cells, exogenous transfection of miR-518b reduced the expression of Rap1b, and dual-luciferase reporter assay validated Rap1b as the direct target of miR-518b. The small RNA could increase the BrdU incorporation and the ratio of cells at S phase, and enhance the phosphorylation of Raf-1 and ERK1/2. Such growth-promoting effect could be efficiently reversed by Rap1b overexpression. The data indicate that miR-518b can promote trophoblast cell proliferation via Rap1b-Ras-MAPK pathway, and the aberrant upregulation of miR-518b in preeclamptic placenta may contribute to the excessive trophoblast proliferation. The study provides new evidence to further understand the etiology of preeclampsia. PMID- 29599750 TI - Postoperative Neck Ultrasonography Surveillance After Thyroidectomy in Patients With Medullary Thyroid Carcinoma: A Multicenter Study. AB - Background: For detecting tumor recurrence of medullary thyroid carcinoma (MTC) in the neck, an appropriate frequency and interval of postoperative ultrasonography (US) surveillance remains unclear. This study aimed to assess an appropriate interval and frequency of postoperative neck US surveillance for detecting tumor recurrence in patients who had undergone thyroid surgery due to MTC. Methods: A total of 86 patients who had undergone thyroid surgery for the treatment of MTC and had at least one postoperative US follow-up examination at any of nine affiliated hospitals were included. Postoperative follow-up US, clinical, and histopathological results of patients were reviewed. The tumor recurrence/persistence rate of MTC was investigated, and the interval and session number of postoperative follow-up US and clinicopathologic factors were compared between tumor recurrence/persistence and non-recurrence groups. Results: Of the 86 patients, 22 (25.6%) showed tumor recurrence/persistence. Of the 22 patients with tumor recurrence/persistence, 11 (50%) showed structural recurrence/persistence in the neck on follow-up US. In these 11 patients, the mean interval and session number of postoperative follow-up US between initial surgery and the first US detection of recurrence/persistence was 41.3 +/- 39.3 months (range, 6-128 months) and 2.6 +/- 2.3 (range, 1-8), respectively. On follow-up US, 6 (54.5%, 6/11) were diagnosed with tumor recurrence/persistence within 3 years of the initial surgery. Tumor recurrence/persistence was significantly correlated with TNM stage (p < 0.001) and multiplicity/bilaterality (p = 0.013). Conclusion: For detecting MTC recurrence/persistence, postoperative US surveillance at 1-year intervals may be sufficient within the first 3 years after thyroid surgery, but depending on the presence of relevant risk factors, annual or biannual US surveillance may be recommendable for 4-10 years after thyroid surgery. PMID- 29599751 TI - Circadian Rhythms and Clock Genes in Reproduction: Insights From Behavior and the Female Rabbit's Brain. AB - Clock gene oscillations are necessary for a successful pregnancy and parturition, but little is known about their function during lactation, a period demanding from the mother multiple physiological and behavioral adaptations to fulfill the requirements of the offspring. First, we will focus on circadian rhythms and clock genes in reproductive tissues mainly in rodents. Disruption of circadian rhythms or proper rhythmic oscillations of clock genes provoke reproductive problems, as found in clock gene knockout mice. Then, we will focus mainly on the rabbit doe as this mammal nurses the young just once a day with circadian periodicity. This daily event synchronizes the behavior and the activity of specific brain regions critical for reproductive neuroendocrinology and maternal behavior, like the preoptic area. This region shows strong rhythms of the PER1 protein (product of the Per1 clock gene) associated with circadian nursing. Additionally, neuroendocrine cells related to milk production and ejections are also synchronized to daily nursing. A threshold of suckling is necessary to entrain once a day nursing; this process is independent of milk output as even virgin does (behaving maternally following anosmia) can display circadian nursing behavior. A timing motivational mechanism may regulate such behavior as mesolimbic dopaminergic cells are entrained by daily nursing. Finally, we will explore about the clinical importance of circadian rhythms. Indeed, women in chronic shift-work schedules show problems in their menstrual cycles and pregnancies and also have a high risk of preterm delivery, making this an important field of translational research. PMID- 29599752 TI - Transcriptional Response of Staphylococcus aureus to Sunlight in Oxic and Anoxic Conditions. AB - The transcriptional response of Staphylococcus aureus strain Newman to sunlight exposure was investigated under both oxic and anoxic conditions using RNA sequencing to gain insight into potential mechanisms of inactivation. S. aureus is a pathogenic bacterium detected at recreational beaches which can cause gastrointestinal illness and skin infections, and is of increasing public health concern. To investigate the S. aureus photostress response in oligotrophic seawater, S. aureus cultures were suspended in seawater and exposed to full spectrum simulated sunlight. Experiments were performed under oxic or anoxic conditions to gain insight into the effects of oxygen-mediated and non-oxygen mediated inactivation mechanisms. Transcript abundance was measured after 6 h of sunlight exposure using RNA sequencing and was compared to transcript abundance in paired dark control experiments. Culturable S. aureus decayed following biphasic inactivation kinetics with initial decay rate constants of 0.1 and 0.03 m2 kJ-1 in oxic and anoxic conditions, respectively. RNA sequencing revealed that 71 genes had different transcript abundance in the oxic sunlit experiments compared to dark controls, and 18 genes had different transcript abundance in the anoxic sunlit experiments compared to dark controls. The majority of genes showed reduced transcript abundance in the sunlit experiments under both conditions. Three genes (ebpS, NWMN_0867, and NWMN_1608) were found to have the same transcriptional response to sunlight between both oxic and anoxic conditions. In the oxic condition, transcripts associated with porphyrin metabolism, nitrate metabolism, and membrane transport functions were increased in abundance during sunlight exposure. Results suggest that S. aureus responds differently to oxygen dependent and oxygen-independent photostress, and that endogenous photosensitizers play an important role during oxygen-dependent indirect photoinactivation. PMID- 29599753 TI - Multiple Modes of Nematode Control by Volatiles of Pseudomonas putida 1A00316 from Antarctic Soil against Meloidogyne incognita. AB - Pseudomonas putida 1A00316 isolated from Antarctic soil showed nematicidal potential for biological control of Meloidogyne incognita; however, little was known about whether strain 1A00316 could produce volatile organic compounds (VOCs), and if they had potential for use in biological control against M. incognita. In this study, VOCs produced by a culture filtrate of P. putida 1A00316 were evaluated by in vitro experiments in three-compartment Petri dishes and 96-well culture plates. Our results showed that M. incognita juveniles gradually reduced their movement within 24-48 h of incubation with mortality ranging from 6.49 to 86.19%, and mostly stopped action after 72 h. Moreover, egg hatching in culture filtrates of strain 1A00316 was much reduced compared to that in sterile distilled water or culture medium. Volatiles from P. putida 1A00316 analysis carried out by solid-phase micro-extraction gas chromatography-mass spectrometry (SPME-GC/MS) included dimethyl-disulfide, 1-undecene, 2-nonanone, 2 octanone, (Z)-hexen-1-ol acetate, 2-undecanone, and 1-(ethenyloxy)-octadecane. Of these, dimethyl-disulfide, 2-nonanone, 2-octanone, (Z)-hexen-1-ol acetate, and 2 undecanone had strong nematicidal activity against M. incognita J2 larvae by direct-contact in 96-well culture plates, and only 2-undecanone acted as a fumigant. In addition, the seven VOCs inhibited egg hatching of M. incognita both by direct-contact and by fumigation. All of the seven VOCs repelled M. incognita J2 juveniles in 2% water agar Petri plates. These results show that VOCs from strain 1A00316 act on different stages in the development of M. incognita via nematicidal, fumigant, and repellent activities and have potential for development as agents with multiple modes of control of root-knot nematodes. PMID- 29599754 TI - Generalized Growth of Estuarine, Household and Clinical Isolates of Pseudomonas aeruginosa. AB - Pseudomonas aeruginosa is an opportunistic pathogen of particular concern to immune-compromised people, such as cystic fibrosis patients and burn victims. These bacteria grow in built environments including hospitals and households, and in natural environments such as rivers and estuaries. However, there is conflicting evidence whether recent environments like the human lung and open ocean affect P. aeruginosa growth performance in alternate environments. We hypothesized that bacteria recently isolated from dissimilar habitats should grow differently in media containing artificial versus natural resources. To test this idea, we examined growth of P. aeruginosa isolates from three environments (estuary, household, and clinic) in three media types: minimal-glucose lab medium, and media prepared from sugar maple leaves or big bluestem grass. We used automated spectrophotometry to measure high-resolution growth curves for all isolate by media combinations, and studied two fitness parameters: growth rate and maximum population density. Results showed high variability in growth rate among isolates, both overall and in its dependence on assay media, but this variability was not associated with habitat of isolation. In contrast, total growth (change in absorbance over the experiment) differed overall among habitats of isolation, and there were media-specific differences in mean total growth among habitats of isolation, and in among-habitat variability in the media specific response. This was driven primarily by greater total growth of estuary isolates when compared with those from other habitats of origin, and greater media-specific variability among household isolates than those from other habitats of origin. Taken together, these results suggest that for growth rate P. aeruginosa bacteria appear to be broad generalists without regard to current or recent habitat, whereas for total growth a signature of recent ecological history can be detected. PMID- 29599755 TI - Analyzing AbrB-Knockout Effects through Genome and Transcriptome Sequencing of Bacillus licheniformis DW2. AB - As an industrial bacterium, Bacillus licheniformis DW2 produces bacitracin which is an important antibiotic for many pathogenic microorganisms. Our previous study showed AbrB-knockout could significantly increase the production of bacitracin. Accordingly, it was meaningful to understand its genome features, expression differences between wild and AbrB-knockout (DeltaAbrB) strains, and the regulation of bacitracin biosynthesis. Here, we sequenced, de novo assembled and annotated its genome, and also sequenced the transcriptomes in three growth phases. The genome of DW2 contained a DNA molecule of 4,468,952 bp with 45.93% GC content and 4,717 protein coding genes. The transcriptome reads were mapped to the assembled genome, and obtained 4,102~4,536 expressed genes from different samples. We investigated transcription changes in B. licheniformis DW2 and showed that DeltaAbrB caused hundreds of genes up-regulation and down-regulation in different growth phases. We identified a complete bacitracin synthetase gene cluster, including the location and length of bacABC, bcrABC, and bacT, as well as their arrangement. The gene cluster bcrABC were significantly up-regulated in DeltaAbrB strain, which supported the hypothesis in previous study of bcrABC transporting bacitracin out of the cell to avoid self-intoxication, and was consistent with the previous experimental result that DeltaAbrB could yield more bacitracin. This study provided a high quality reference genome for B. licheniformis DW2, and the transcriptome data depicted global alterations across two strains and three phases offered an understanding of AbrB regulation and bacitracin biosynthesis through gene expression. PMID- 29599756 TI - Mesobuthus Venom-Derived Antimicrobial Peptides Possess Intrinsic Multifunctionality and Differential Potential as Drugs. AB - Animal venoms are a mixture of peptides and proteins that serve two basic biological functions: predation and defense against both predators and microbes. Antimicrobial peptides (AMPs) are a common component extensively present in various scorpion venoms (herein abbreviated as svAMPs). However, their roles in predation and defense against predators and potential as drugs are poorly understood. Here, we report five new venom peptides with antimicrobial activity from two Mesobuthus scorpion species. These alpha-helical linear peptides displayed highly bactericidal activity toward all the Gram-positive bacteria used here but differential activity against Gram-negative bacteria and fungi. In addition to the antibiotic activity, these AMPs displayed lethality to houseflies and hemotoxin-like toxicity on mice by causing hemolysis, tissue damage and inducing inflammatory pain. Unlike AMPs from other origins, these venom-derived AMPs seem to be unsuitable as anti-infective drugs due to their high hemolysis and low serum stability. However, MeuTXKbeta1, a known two-domain Mesobuthus AMP, is an exception since it exhibits high activity toward antibiotic resistant Staphylococci clinical isolates with low hemolysis and high serum stability. The findings that the classical AMPs play predatory and defensive roles indicate that the multifunctionality of scorpion venom components is an intrinsic feature likely evolved by natural selection from microbes, prey and predators of scorpions. This definitely provides an excellent system in which one can study how a protein adaptively evolves novel functions in a new environment. Meantimes, new strategies are needed to remove the toxicity of svAMPs on eukaryotic cells when they are used as leads for anti-infective drugs. PMID- 29599757 TI - Interplay Between Capsule Expression and Uracil Metabolism in Streptococcus pneumoniae D39. AB - Pyrimidine nucleotides play an important role in the biosynthesis of activated nucleotide sugars (NDP-sugars). NDP-sugars are the precursors of structural polysaccharides in bacteria, including capsule, which is a major virulence factor of the human pathogen S. pneumoniae. In this work, we identified a spontaneous non-reversible mutant of strain D39 that displayed a non-producing capsule phenotype. Whole-genome sequencing analysis of this mutant revealed several non synonymous single base modifications, including in genes of the de novo synthesis of pyrimidines and in the -10 box of capsule operon promoter (Pcps). By directed mutagenesis we showed that the point mutation in Pcps was solely responsible for the drastic decrease in capsule expression. We also demonstrated that D39 subjected to uracil deprivation shows increased biomass and decreased Pcps activity and capsule amounts. Importantly, Pcps expression is further decreased by mutating the first gene of the de novo synthesis of pyrimidines, carA. In contrast, the absence of uracil from the culture medium showed no effect on the spontaneous mutant strain. Co-cultivation of the wild-type and the mutant strain indicated a competitive advantage of the spontaneous mutant (non-producing capsule) in medium devoid of uracil. We propose a model in that uracil may act as a signal for the production of different capsule amounts in S. pneumoniae. PMID- 29599758 TI - Metatranscriptomics and Amplicon Sequencing Reveal Mutualisms in Seagrass Microbiomes. AB - Terrestrial plants benefit from many well-understood mutualistic relationships with root- and leaf-associated microbiomes, but relatively little is known about these relationships for seagrass and other aquatic plants. We used 16S rRNA gene amplicon sequencing and metatranscriptomics to assess potential mutualisms between microorganisms and the seagrasses Zostera marina and Zostera japonica collected from mixed beds in Netarts Bay, OR, United States. The phylogenetic composition of leaf-, root-, and water column-associated bacterial communities were strikingly different, but these communities were not significantly different between plant species. Many taxa present on leaves were related to organisms capable of consuming the common plant metabolic waste product methanol, and of producing agarases, which can limit the growth of epiphytic algae. Taxa present on roots were related to organisms capable of oxidizing toxic sulfur compounds and of fixing nitrogen. Metatranscriptomic sequencing identified expression of genes involved in all of these microbial metabolic processes at levels greater than typical water column bacterioplankton, and also identified expression of genes involved in denitrification and in bacterial synthesis of the plant growth hormone indole-3-acetate. These results provide the first evidence using metatranscriptomics that seagrass microbiomes carry out a broad range of functions that may benefit their hosts, and imply that microbe-plant mutualisms support the health and growth of aquatic plants. PMID- 29599759 TI - Emergence of CD4+ and CD8+ Polyfunctional T Cell Responses Against Immunodominant Lytic and Latent EBV Antigens in Children With Primary EBV Infection. AB - Long term carriers were shown to generate robust polyfunctional T cell (PFC) responses against lytic and latent antigens of Epstein-Barr virus (EBV). However, the time of emergence of PFC responses against EBV antigens, pattern of immunodominance and difference between CD4+ and CD8+ T cell responses during various stages of EBV infection are not clearly understood. A longitudinal study was performed to assess the development of antigen-specific PFC responses in children diagnosed to have primary symptomatic (infectious mononucleosis [IM]) and asymptomatic (AS) EBV infection. Evaluation of IFN-gamma secreting CD8+ T cell responses upon stimulation by HLA class I-specific peptides of EBV lytic and latent proteins by ELISPOT assay followed by assessment of CD4+ and CD8+ PFC responses upon stimulation by a panel of overlapping EBV peptides for co expression of IFN-gamma, TNF-alpha, IL-2, perforin and CD107a by flow cytometry were performed. Cytotoxicity of T cells against autologous lymphoblastoid cell lines (LCLs) as well as EBV loads in PBMC and plasma were also determined. Both IM and AS patients had elevated PBMC and plasma viral loads which declined steadily during a 12-month period from the time of diagnosis whilst decrease in the magnitude of CD8+ T cell responses toward EBV lytic peptides in contrast to increase toward latent peptides was shown with no significant difference between those of IM and AS patients. Both lytic and latent antigen-specific CD4+ and CD8+ T cells demonstrated polyfunctionality (defined as greater or equal to three functions) concurrent with enhanced cytotoxicity against autologous LCLs and steady decrease in plasma and PBMC viral loads over time. Immunodominant peptides derived from BZLF1, BRLF1, BMLF1 and EBNA3A-C proteins induced the highest proportion of CD8+ as well as CD4+ PFC responses. Diverse functional subtypes of both CD4+ and CD8+ PFCs were shown to emerge at 6-12 months. In conclusion, EBV antigen-specific CD4+ and CD8+ PFC responses emerge during the first year of primary EBV infection, with greatest responses toward immunodominant epitopes in both lytic and latent proteins, correlating to steady decline in PBMC and plasma viral loads. PMID- 29599760 TI - Characterization of Tail Sheath Protein of N4-Like Phage phiAxp-3. AB - Achromobacter phage phiAxp-3, an N4-like bacteriophage, specifically recognize Achromobacter xylosoxidans lipopolysaccharide (LPS) as its receptor. PhiAxp-3 tail sheath protein (TSP, ORF69) shares 54% amino acid sequence identity with the TSP of phage N4 (gp65); the latter functions as a receptor binding protein and interacts with the outer membrane receptor NfrA of its host bacterium. Thus, we hypothesized that ORF69 is the receptor-binding protein of phiAxp-3. In the present study, a series of ORF69 truncation variants was constructed to identify the part(s) of this protein essential for binding to A. xylosoxidans LPS. Phage adsorption and enzyme-linked immunosorbent assay showed that amino acids 795-1195 of the TSP, i.e., ORF69(795-1195), are sufficient and essential for receptor and binding. The optimum temperature and pH for the functions of ORF69 and ORF69(795 1195) are 4/25 degrees C and 7, respectively. In vitro cytotoxicity assays showed that ORF69 and ORF69(795-1195) were respectively toxic and non-toxic to a human immortalized normal hepatocyte cell line (LO2; doses: 0.375-12 MUg). The potential of this non-toxic truncated version of phiASP-3 TSP for clinical applications is discussed. PMID- 29599761 TI - Evaluation of the Efficacy and Cross-Protective Immunity of Live-Attenuated Chimeric PCV1-2b Vaccine Against PCV2b and PCV2d Subtype Challenge in Pigs. AB - Porcine circovirus type 2 (PCV2) commercial vaccines are either inactivated PCV2 isolates or subunit vaccine based on the Cap protein of PCV2. Currently, no live attenuated vaccines are yet available. Although the predominant circulating subtype worldwide is PCV2b, the emerging PCV2d subtype is also increasingly associated with PCV disease. In this study, piglets were inoculated with a live attenuated chimeric PCV1-2b vaccine before challenged with PCV2b and PCV2d isolates. Thirty-two piglets were randomly divided into seven groups: negative (sham-vaccinated, sham-challenged), VAC+PCV2b (PCV1-2b vaccinated, PCV2b challenged), VAC+PCV2d (PCV1-2b vaccinated, PCV2d-challenged), CHAL+PCV2b (sham vaccinated, PCV2b-challenged), CHAL+PCV2d (sham-vaccinated, PCV2d-challenged), CV+PCV2b (commercial-vaccinated, PCV2b-challenged), and CV+PCV2d (commercial vaccinated, PCV2d-challenged). The results showed that vaccinated challenged groups demonstrated high levels of anti-PCV2 antibody and reduced PCV2b and PCV2d loads both in serum and nasal swabs compared with the challenge-only groups. PCV2 DNA was detected in the superficial inguinal lymph nodes of only one pig in each of the VAC+PCV2b and VAC+PCV2d groups (group mean values, 101.81 and 101.77 genomic copies/g, respectively), which was significantly lower than those in CHAL+PCV2b and CHAL+PCV2d animals (group mean values, 1011.65 and 1010.60 genomic copies/g, respectively; P < 0.01). In addition, PCV2 DNA in each of the VAC+PCV2b and VAC+PCV2d groups was significantly lower than those in CV+PCV2b and CV+PCV2d animals (group mean values, 108.47 and 108.34 genomic copies/g, respectively; P < 0.01), indicating that the live-attenuated PCV1-2b vaccine was more effective than commercial vaccine. The live-attenuated PCV1-2b vaccine was effective in reducing PCV2b/PCV2d viremia, shedding, and tissue viral loads in vaccinated challenged pigs compared with challenge-only piglets, indicating that the PCV1-2b prototype vaccine is a good candidate for a live-attenuated vaccine against both PCV2b and PCV2d subtypes. And we first revealed that the live-attenuated PCV1-2b vaccine could protect piglets from challenge with either PCV2b or PCV2d equivalently. PMID- 29599762 TI - PHB Biosynthesis Counteracts Redox Stress in Herbaspirillum seropedicae. AB - The ability of bacteria to produce polyhydroxyalkanoates such as poly(3 hydroxybutyrate) (PHB) enables provision of a carbon storage molecule that can be mobilized under demanding physiological conditions. However, the precise function of PHB in cellular metabolism has not been clearly defined. In order to determine the impact of PHB production on global physiology, we have characterized the properties of a DeltaphaC1 mutant strain of the diazotrophic bacterium Herbaspirillum seropedicae. The absence of PHB in the mutant strain not only perturbs redox balance and increases oxidative stress, but also influences the activity of the redox-sensing Fnr transcription regulators, resulting in significant changes in expression of the cytochrome c-branch of the electron transport chain. The synthesis of PHB is itself dependent on the Fnr1 and Fnr3 proteins resulting in a cyclic dependency that couples synthesis of PHB with redox regulation. Transcriptional profiling of the DeltaphaC1 mutant reveals that the loss of PHB synthesis affects the expression of many genes, including approximately 30% of the Fnr regulon. PMID- 29599763 TI - Streptococcus suis - The "Two Faces" of a Pathobiont in the Porcine Respiratory Tract. AB - Streptococcus (S.) suis is a frequent early colonizer of the upper respiratory tract of pigs. In fact, it is difficult to find S. suis-free animals under natural conditions, showing the successful adaptation of this pathogen to its porcine reservoir host. On the other hand, S. suis can cause life-threatening diseases and represents the most important bacterial cause of meningitis in pigs worldwide. Notably, S. suis can also cause zoonotic infections, such as meningitis, septicemia, endocarditis, and other diseases in humans. In Asia, it is classified as an emerging zoonotic pathogen and currently considered as one of the most important causes of bacterial meningitis in adults. The "two faces" of S. suis, one of a colonizing microbe and the other of a highly invasive pathogen, have raised many questions concerning the interpretation of diagnostic detection and the definition of virulence. Thus, one major research challenge is the identification of virulence-markers which allow differentiation of commensal and virulent strains. This is complicated by the high phenotypic and genotypic diversity of S. suis, as reflected by the occurrence of (at least) 33 capsular serotypes. In this review, we present current knowledge in the context of S. suis as a highly diverse pathobiont in the porcine respiratory tract that can exploit disrupted host homeostasis to flourish and promote inflammatory processes and invasive diseases in pigs and humans. PMID- 29599764 TI - A Dual Role for the Bacillus anthracis Master Virulence Regulator AtxA: Control of Sporulation and Anthrax Toxin Production. AB - Bacillus anthracis is an endemic soil bacterium that exhibits two different lifestyles. In the soil environment, B. anthracis undergoes a cycle of saprophytic growth, sporulation, and germination. In mammalian hosts, the pathogenic lifestyle of B. anthracis is spore germination followed by vegetative cell replication, but cells do not sporulate. During infection, and in specific culture conditions, transcription of the structural genes for the anthrax toxin proteins and the biosynthetic operon for capsule synthesis is positively controlled by the regulatory protein AtxA. A critical role for the atxA gene in B. anthracis virulence has been established. Here we report an inverse relationship between toxin production and sporulation that is linked to AtxA levels. During culture in conditions favoring sporulation, B. anthracis produces little to no AtxA. When B. anthracis is cultured in conditions favoring toxin gene expression, AtxA is expressed at relatively high levels and sporulation rate and efficiency are reduced. We found that a mutation within the atxA promoter region resulting in AtxA over-expression leads to a marked sporulation defect. The sporulation phenotype of the mutant is dependent upon pXO2-0075, an atxA regulated open reading frame located on virulence plasmid pXO2. The predicted amino acid sequence of the pXO2-0075 protein has similarity to the sensor domain of sporulation sensor histidine kinases. It was shown previously that pXO2-0075 overexpression suppresses sporulation. We have designated pXO2-0075 "skiA" for "sporulation kinase inhibitor." Our results indicate that in addition to serving as a positive regulator of virulence gene expression, AtxA modulates B. anthracis development. PMID- 29599765 TI - Herpesviruses in the Activated Phosphatidylinositol-3-Kinase-delta Syndrome. AB - The phosphatidylinositol-3-kinase (PI3K)/Akt pathway is important for multiple stages of herpesvirus replication including virus entry, replication, latency, and reactivation. Recently, patients with gain-of-function mutations in the p110delta-catalytic subunit of PI3K or in the p85-regulatory subunit of PI3K have been reported. These patients have constitutively active PI3K with hyperactivation of Akt. They present with lymphoproliferation and often have infections, particularly recurrent respiratory infections and/or severe virus infections. The most frequent virus infections are due to Epstein-Barr virus (EBV) and cytomegalovirus (CMV); patients often present with persistent EBV and/or CMV viremia, EBV lymphoproliferative disease, or CMV lymphadenitis. No patients have been reported with CMV pneumonia, colitis, or retinitis. Other herpesvirus infections have included herpes simplex pneumonia, recurrent zoster, and varicella after vaccination with the varicella vaccine. Additional viral infections have included adenovirus viremia, severe warts, and extensive Molluscum contagiosum virus infection. The increased susceptibility to virus infections in these patients is likely due to a reduced number of long-lived memory CD8 T cells and an increased number of terminally differentiated effector CD8 T cells. PMID- 29599766 TI - Room Temperature Stable PspA-Based Nanovaccine Induces Protective Immunity. AB - Streptococcus pneumoniae is a major causative agent of pneumonia, a debilitating disease particularly in young and elderly populations, and is the leading worldwide cause of death in children under the age of five. While there are existing vaccines against S. pneumoniae, none are protective across all serotypes. Pneumococcal surface protein A (PspA), a key virulence factor of S. pneumoniae, is an antigen that may be incorporated into future vaccines to address the immunological challenges presented by the diversity of capsular antigens. PspA has been shown to be immunogenic and capable of initiating a humoral immune response that is reactive across approximately 94% of pneumococcal strains. Biodegradable polyanhydrides have been studied as a nanoparticle-based vaccine (i.e., nanovaccine) platform to stabilize labile proteins, to provide adjuvanticity, and enhance patient compliance by providing protective immunity in a single dose. In this study, we designed a room temperature stable PspA-based polyanhydride nanovaccine that eliminated the need for a free protein component (i.e., 100% encapsulated within the nanoparticles). Mice were immunized once with the lead nanovaccine and upon challenge, presented significantly higher survival rates than animals immunized with soluble protein alone, even with a 25-fold reduction in protein dose. This lead nanovaccine formulation performed similarly to protein adjuvanted with Alum, however, with much less tissue reactogenicity at the site of immunization. By eliminating the free PspA from the nanovaccine formulation, the lead nanovaccine was efficacious after being stored dry for 60 days at room temperature, breaking the need for maintaining the cold chain. Altogether, this study demonstrated that a single dose PspA-based nanovaccine against S. pneumoniae induced protective immunity and provided thermal stability when stored at room temperature for at least 60 days. PMID- 29599767 TI - Immunobiotics for the Bovine Host: Their Interaction with Intestinal Epithelial Cells and Their Effect on Antiviral Immunity. AB - The scientific community has reported several cases of microbes that exhibit elevated rates of antibiotic resistance in different regions of the planet. Due to this emergence of antimicrobial resistant microorganisms, the use of antibiotics as promoters of livestock animals' growth is being banned in most countries around the world. One of the challenges of agricultural immunology therefore is to find alternatives by modulating the immune system of animals in drug-independent safe food production systems. In this regard, in an effort to supplant antibiotics from bovine feeds, several alternatives were proposed including the use of immunomodulatory probiotics (immunobiotics). The purpose of this review is to provide an update of the status of the modulation of intestinal antiviral innate immunity of the bovine host by immunobiotics, and the beneficial impact of immunobiotics on viral infections, focused on intestinal epithelial cells (IECs). The results of our group, which demonstrate the capacity of immunobiotic strains to beneficially modulate Toll-like receptor 3-triggered immune responses in bovine IECs and improve the resistance to viral infections, are highlighted. This review provides comprehensive information on the innate immune response of bovine IECs against virus, which can be further investigated for the development of strategies aimed to improve defenses in the bovine host. PMID- 29599768 TI - Mother's Milk: A Purposeful Contribution to the Development of the Infant Microbiota and Immunity. AB - Breast milk is the perfect nutrition for infants, a result of millions of years of evolution. In addition to providing a source of nutrition, breast milk contains a diverse array of microbiota and myriad biologically active components that are thought to guide the infant's developing mucosal immune system. It is believed that bacteria from the mother's intestine may translocate to breast milk and dynamically transfer to the infant. Such interplay between mother and her infant is a key to establishing a healthy infant intestinal microbiome. These intestinal bacteria protect against many respiratory and diarrheal illnesses, but are subject to environmental stresses such as antibiotic use. Orchestrating the development of the microbiota are the human milk oligosaccharides (HMOs), the synthesis of which are partially determined by the maternal genotype. HMOs are thought to play a role in preventing pathogenic bacterial adhesion though multiple mechanisms, while also providing nutrition for the microbiome. Extracellular vesicles (EVs), including exosomes, carry a diverse cargo, including mRNA, miRNA, and cytosolic and membrane-bound proteins, and are readily detectable in human breast milk. Strongly implicated in cell-cell signaling, EVs could therefore may play a further role in the development of the infant microbiome. This review considers the emerging role of breast milk microbiota, bioactive HMOs, and EVs in the establishment of the neonatal microbiome and the consequent potential for modulation of neonatal immune system development. PMID- 29599769 TI - Trib1 Is Overexpressed in Systemic Lupus Erythematosus, While It Regulates Immunoglobulin Production in Murine B Cells. AB - Systemic lupus erythematosus (SLE) is a severe and heterogeneous autoimmune disease with a complex genetic etiology, characterized by the production of various pathogenic autoantibodies, which participate in end-organ damages. The majority of human SLE occurs in adults as a polygenic disease, and clinical flares interspersed with silent phases of various lengths characterize the usual evolution of the disease in time. Trying to understand the mechanism of the different phenotypic traits of the disease, and considering the central role of B cells in SLE, we previously performed a detailed wide analysis of gene expression variation in B cells from quiescent SLE patients. This analysis pointed out an overexpression of TRIB1. TRIB1 is a pseudokinase that has been implicated in the development of leukemia and also metabolic disorders. It is hypothesized that Trib1 plays an adapter or scaffold function in signaling pathways, notably in MAPK pathways. Therefore, we planned to understand the functional significance of TRIB1 overexpression in B cells in SLE. We produced a new knock-in model with B cell-specific overexpression of Trib1. We showed that overexpression of Trib1 specifically in B cells does not impact B cell development nor induce any development of SLE symptoms in the mice. By contrast, Trib1 has a negative regulatory function on the production of immunoglobulins, notably IgG1, but also on the production of autoantibodies in an induced model. We observed a decrease of Erk activation in BCR-stimulated Trib1 overexpressing B cells. Finally, we searched for Trib1 partners in B cells by proteomic analysis in order to explore the regulatory function of Trib1 in B cells. Interestingly, we find an interaction between Trib1 and CD72, a negative regulator of B cells whose deficiency in mice leads to the development of autoimmunity. In conclusion, the overexpression of Trib1 could be one of the molecular pathways implicated in the negative regulation of B cells during SLE.

AB - Recent studies suggest that in addition to their common function in the regulation of thrombosis and hemostasis, platelets also contribute to tissue inflammation affecting adaptive immunity. Platelets have a number of pro inflammatory and regulatory mediators stored in their alpha-granules and dense granules, which are promptly released at sites of inflammation or tissue injury. Platelet-derived mediators include cytokines (IL-1alpha, IL-1beta, and TGFbeta1), chemokines (CXCL4 and CCL3), immunomodulatory neurotransmitters (serotonin, dopamine, epinephrine, histamine, and GABA), and other low-molecular-weight mediators. In addition, activated platelets synthesize a number of lipid pro inflammatory mediators such as platelet-activating factor and prostaglandins/thromboxanes. Notably, platelets express multiple toll-like receptors and MHC class I on their surface and store IgG in their alpha-granules. Platelet-derived factors are highly effective in directly or indirectly modulating the priming and effector function of various subsets of T cells. Besides secreting soluble factors, activated platelets upregulate a number of integrins, adhesion molecules, and lectins, leading to the formation of platelet T cells aggregates. Activated platelets are able to instantly release neurotransmitters acting similar to neuronal presynaptic terminals, affecting CD4 T cells and other cells in close contact with them. The formation of platelet-T cell aggregates modulates the functions of T cells via direct cell-cell contact interactions and the local release of soluble factors including neurotransmitters. New data suggest an important role for platelets as neuronal and innate-like cells that directly recognize damage- or pathogen- associated molecular patterns and instantly communicate with T cells.

AB - To determine the effect of the microbiota on vitamin D metabolism, serum 25 hydroxyvitamin D(25D), 24,25-dihydroxyvitamin D (24,25D), and 1,25 dihydroxyvitamin D (1,25D) were measured in germ-free (GF) mice before and after conventionalization (CN). GF mice had low levels of 25D, 24,25D, and 1,25D and were hypocalcemic. CN of the GF mice with microbiota, for 2 weeks recovered 25D, 24,25D, and 1,25D levels. Females had more 25D and 24,25D than males both as GF mice and after CN. Introducing a limited number of commensals (eight commensals) increased 25D and 24,25D to the same extent as CN. Monocolonization with the enteric pathogen Citrobacter rodentium increased 25D and 24,25D, but the values only increased after 4 weeks of C. rodentium colonization when inflammation resolved. Fibroblast growth factor (FGF) 23 was extremely high in GF mice. CN resulted in an increase in TNF-alpha expression in the colon 2 days after CN that coincided with a reduction in FGF23 by 3 days that eventually normalized 25D, 24,25D, 1,25D at 1-week post-CN and reinstated calcium homeostasis. Neutralization of FGF23 in GF mice raised 1,25D, without CN, demonstrating that the high FGF23 levels were responsible for the low calcium and 1,25D in GF mice. The microbiota induce inflammation in the GF mice that inhibits FGF23 to eventually reinstate homeostasis that includes increased 25D, 24,25D, and 1,25D levels. The microbiota through FGF23 regulates vitamin D metabolism. PMID- 29599770 TI - Dendritic Cells and Programmed Death-1 Blockade: A Joint Venture to Combat Cancer. AB - Two decades of clinical cancer research with dendritic cell (DC)-based vaccination have proved that this type of personalized medicine is safe and has the capacity to improve survival, but monotherapy is unlikely to cure the cancer. Designed to empower the patient's antitumor immunity, huge research efforts are set to improve the efficacy of next-generation DC vaccines and to find synergistic combinations with existing cancer therapies. Immune checkpoint approaches, aiming to breach immune suppression and evasion to reinforce antitumor immunity, have been a revelation in the immunotherapy field. Early success of therapeutic antibodies blocking the programmed death-1 (PD-1) pathway has sparked the development of novel inhibitors and combination therapies. Hence, merging immunoregulatory tumor-specific DC strategies with PD-1-targeted approaches is a promising path to explore. In this review, we focus on the role of PD-1-signaling in DC-mediated antitumor immunity. In the quest of exploiting the full potential of DC therapy, different strategies to leverage DC immunopotency by impeding PD-1-mediated immune regulation are discussed, including the most advanced research on targeted therapeutic antibodies, lessons learned from chemotherapy-induced immune activation, and more recent developments with soluble molecules and gene-silencing techniques. An overview of DC/PD-1 immunotherapy combinations that are currently under preclinical and clinical investigation substantiates the clinical potential of such combination strategies. PMID- 29599773 TI - Negative Regulation of Interferon-beta Production by Alternative Splicing of Tumor Necrosis Factor Receptor-Associated Factor 3 in Ducks. AB - Tumor necrosis factor receptor-associated factor 3 (TRAF3), an intracellular signal transducer, is identified as an important component of Toll-like receptors and RIG-I-like receptors induced type I interferon (IFN) signaling pathways. Previous studies have clarified TRAF3 function in mammals, but little is known about the role of TRAF3 in ducks. Here, we cloned and characterized the full length duck TRAF3 (duTRAF3) gene and an alternatively spliced isoform of duTRAF3 (duTRAF3-S) lacking the fragment encoding amino acids 217-319, from duck embryo fibroblasts (DEFs). We found that duTRAF3 and duTRAF3-S played different roles in regulating IFN-beta production in DEFs. duTRAF3 through its TRAF domain interacted with duMAVS or duTRIF, leading to the production of IFN-beta. However, duTRAF3-S, containing the TRAF domain, was unable to bind duMAVS or duTRIF due to the intramolecular binding between the N- and C-terminal of duTRAF3-S that blocked the function of its TRAF domain. Further analysis identified that duTRAF3 S competed with duTRAF3 itself for binding to duTRAF3, perturbing duTRAF3 self association, which impaired the assembly of duTRAF3-duMAVS/duTRIF complex, ultimately resulted in a reduced production of IFN-beta. These findings suggest that duTRAF3 is an important regulator of duck innate immune signaling and reveal a novel mechanism for the negative regulation of IFN-beta production via changing the formation of the homo-oligomerization of wild molecules, implying a novel regulatory role of truncated proteins. PMID- 29599774 TI - Chemokine CCL4 Induces Vascular Endothelial Growth Factor C Expression and Lymphangiogenesis by miR-195-3p in Oral Squamous Cell Carcinoma. AB - The inflammatory chemokine (C-C motif) ligand 4 (CCL4) plays an important role in the pathogenesis and progression of cancer. In particular, higher serum CCL4 levels in patients with oral squamous cell carcinoma (OSCC) are associated with a more advanced stage of disease. OSCC accounts for approximately 95% of oral cancer in Taiwan and has a poor prognosis, due to aggressive local invasion and metastasis, leading to recurrence. OSCC spreads preferentially through lymphatic vessels and has the propensity to metastasize to the cervical lymph nodes even in the early stage of disease. Vascular endothelial growth factor C (VEGF-C) is an essential regulator of lymphangiogenesis. In particular, VEGF-C is specific to lymphatic vessel development, and VEGF-C expression levels have been found to directly correlate with lymph node metastasis in OSCC. However, it is unclear as to whether CCL4 correlates with VEGF-C expression and lymphangiogenesis in OSCC. We found that CCL4 increased VEGF-C expression and promoted lymphangiogenesis in oral cancer cells in vitro and in vivo. miR-195-3p mimic reversed CCL4-enhanced VEGF-C expression. CCL4 stimulation of oral cancer cells augmented JAK2 and STAT3 phosphorylation. Thus, CCL4 may be a new molecular therapeutic target for inhibition of lymphangiogenesis and metastasis in OSCC. PMID- 29599775 TI - CD86 Expression by Monocytes Influences an Immunomodulatory Profile in Asymptomatic Patients with Chronic Chagas Disease. AB - In the chronic phase of Chagas disease, 60% of the patients develop the asymptomatic form known as indeterminate (IND). The remaining 30% of the patients develop a life-threatening form in which digestive and/or cardiac (CARD) alterations take place. The mechanisms underlying the development of severe forms of Chagas disease remain poorly understood. It is well known that interactions between immune cells such as monocytes and lymphocytes drive immune responses. Further, the co-stimulatory molecules CD80 and CD86 expressed by monocytes and subsets induce lymphocyte activation, thereby triggering cellular immune response. Here, we revealed, for the first time, the functional-phenotypic profile of monocytes subsets in Chagas disease. Using flow cytometry, we evaluated the effect of in vitro stimulation with Trypanosoma cruzi antigens on the expression of the co-stimulatory molecules CD80 and CD86 in different monocyte subsets of patients with IND and CARD clinical forms of Chagas disease. We also assessed the expression of toll-like receptor (TLR)-2, TLR-4, TLR-9, HLA DR, IL-10, and IL-12 in the monocyte subsets and of CTLA-4 and CD28, ligands of CD80 and CD86, in T lymphocytes. CD86 expression in all monocyte subsets was higher in IND patients when compared with non-infected (NI) individuals. After stimulation with T. cruzi, these patients also showed a higher frequency of CD4+CTLA-4+ T lymphocytes than NI individuals. We found an association between CD80 and CD28, and between CD86 and CTLA-4 expression, with a high frequency of regulatory T (Treg) cells in IND patients. We proposed that CD86 may be involved in immunoregulation by its association with CTLA-4 in asymptomatic patients. CD86 and CTLA-4 interaction may influence Treg activation, and this could represent a new strategy to control inflammation and tissue damage. PMID- 29599776 TI - New Vaccine Formulations Containing a Modified Version of the Amastigote 2 Antigen and the Non-Virulent Trypanosoma cruzi CL-14 Strain Are Highly Antigenic and Protective against Leishmania infantum Challenge. AB - Visceral leishmaniasis (VL) is a major public health issue reported as the second illness in mortality among all tropical diseases. Clinical trials have shown that protection against VL is associated with robust T cell responses, especially those producing IFN-gamma. The Leishmania amastigote 2 (A2) protein has been repeatedly described as immunogenic and protective against VL in different animal models; it is recognized by human T cells, and it is also commercially available in a vaccine formulation containing saponin against canine VL. Moving toward a more appropriate formulation for human vaccination, here, we tested a new optimized version of the recombinant protein (rA2), designed for Escherichia coli expression, in combination with adjuvants that have been approved for human use. Moreover, aiming at improving the cellular immune response triggered by rA2, we generated a recombinant live vaccine vector using Trypanosoma cruzi CL-14 non virulent strain, named CL-14 A2. Mice immunized with respective rA2, adsorbed in Alum/CpG B297, a TLR9 agonist recognized by mice and human homologs, or with the recombinant CL-14 A2 parasites through homologous prime-boost protocol, were evaluated for antigen-specific immune responses and protection against Leishmania infantum promastigote challenge. Immunization with the new rA2/Alum/CpG formulations and CL-14 A2 transgenic vectors elicited stronger cellular immune responses than control groups, as shown by increased levels of IFN-gamma, conferring protection against L. infantum challenge. Interestingly, the use of the wild-type CL-14 alone was enough to boost immunity and confer protection, confirming the previously reported immunogenic potential of this strain. Together, these results support the success of both the newly designed rA2 antigen and the ability of T. cruzi CL-14 to induce strong T cell-mediated immune responses against VL in animal models when used as a live vaccine vector. In conclusion, the vaccination strategies explored here reveal promising alternatives for the development of new rA2 vaccine formulations to be translated human clinical trials. PMID- 29599777 TI - Tissue Destruction in Bullous Pemphigoid Can Be Complement Independent and May Be Mitigated by C5aR2. AB - Bullous pemphigoid (BP), the most frequent autoimmune bullous disorder, is a paradigmatic autoantibody-mediated disease associated with autoantibodies against BP180 (type XVII collagen, Col17). Several animal models have been developed that reflect important clinical and immunological features of human BP. Complement activation has been described as a prerequisite for blister formation, however, the recent finding that skin lesions can be induced by anti-Col17 F(ab')2 fragments indicates complement-independent mechanisms to contribute to blister formation in BP. Here, C5-/- mice injected with anti-Col17 IgG showed a reduction of skin lesions by about 50% associated with significantly less skin-infiltrating neutrophils compared to wild-type mice. Reduction of skin lesions and neutrophil infiltration was seen independently of the employed anti-Col17 IgG dose. Further, C5ar1-/- mice were protected from disease development, whereas the extent of skin lesions was increased in C5ar2-/- animals. Pharmacological inhibition of C5a receptor 1 (C5aR1) by PMX53 led to reduced disease activity when applied in a prophylactic setting. In contrast, PMX-53 treatment had no effect when first skin lesions had already developed. While C5aR1 was critically involved in neutrophil migration in vitro, its role for Col17-anti-Col17 IgG immune complex-mediated release of reactive oxygen species from neutrophils was less pronounced. Our data demonstrate that complement-dependent and -independent mechanisms coexist in anti Col17-autoantibody-mediated tissue destruction. C5aR1 and C5aR2 seem to play opposing roles in this process with C5aR1 exerting its primary effect in recruiting inflammatory cells to the skin during the early phase of the disease. Further studies are required to fully understand the role of C5aR2 in autoantibody-mediated skin inflammation.

PMID- 29599780 TI - Bi-Allelic Mutations in STXBP2 Reveal a Complementary Role for STXBP1 in Cytotoxic Lymphocyte Killing. AB - The ability of cytotoxic lymphocytes (CL) to eliminate virus-infected or cancerous target cells through the granule exocytosis death pathway is critical to immune homeostasis. Congenital loss of CL function due to bi-allelic mutations in PRF1, UNC13D, STX11, or STXBP2 leads to a potentially fatal immune dysregulation, familial haemophagocytic lymphohistiocytosis (FHL). This occurs due to the failure of CLs to release functional pore-forming protein perforin and, therefore, inability to kill the target cell. Bi-allelic mutations in partner proteins STXBP2 or STX11 impair CL cytotoxicity due to failed docking/fusion of cytotoxic secretory granules with the plasma membrane. One unique feature of STXBP2- and STX11-deficient patient CLs is that their short term in vitro treatment with a low concentration of IL-2 partially or completely restores natural killer (NK) cell degranulation and cytotoxicity, suggesting the existence of a secondary, yet unknown, pathway for secretory granule exocytosis. In the current report, we studied NK and T-cell function in an individual with late presentation of FHL due to hypomorphic bi-allelic mutations in STXBP2. Intriguingly, in addition to the expected alterations in the STXBP2 and STX11 proteins, we also observed a concomitant significant reduction in the expression of homologous STXBP1 protein and its partner STX1, which had never been implicated in CL function. Further analysis of human NK and T cells demonstrated a functional role for the STXBP1/STX1 axis in NK and CD8+ T-cell cytotoxicity, where it appears to be responsible for as much as 50% of their cytotoxic activity. This discovery suggests a unique and previously unappreciated interplay between STXBP/Munc proteins regulating the same essential granule exocytosis pathway. PMID- 29599778 TI - Discovering Macrophage Functions Using In Vivo Optical Imaging Techniques. AB - Macrophages are an important component of host defense and inflammation and play a pivotal role in immune regulation, tissue remodeling, and metabolic regulation. Since macrophages are ubiquitous in human bodies and have versatile physiological functions, they are involved in virtually every disease, including cancer, diabetes, multiple sclerosis, and atherosclerosis. Molecular biological and histological methods have provided critical information on macrophage biology. However, many in vivo dynamic behaviors of macrophages are poorly understood and yet to be discovered. A better understanding of macrophage functions and dynamics in pathogenesis will open new opportunities for better diagnosis, prognostic assessment, and therapeutic intervention. In this article, we will review the advances in macrophage tracking and analysis with in vivo optical imaging in the context of different diseases. Moreover, this review will cover the challenges and solutions for optical imaging techniques during macrophage intravital imaging. PMID- 29599781 TI - Extracellular Vesicle Subtypes Released From Activated or Apoptotic T-Lymphocytes Carry a Specific and Stimulus-Dependent Protein Cargo. AB - Extracellular vesicles (EVs) are released from nearly all mammalian cells and different EV populations have been described. Microvesicles represent large EVs (LEVs) released from the cellular surface, while exosomes are small EVs (SEVs) released from an intracellular compartment. As it is likely that different stimuli promote the release of distinct EV populations, we analyzed EVs from human lymphocytes considering the respective release stimuli (activation Vs. apoptosis induction). We could clearly separate two EV populations, namely SEVs (average diameter <200 nm) and LEVs (diameter range between 200 and 1000 nm). Morphology and size were analyzed by electron microscopy and nanoparticle tracking analysis. Apoptosis induction caused a massive release of LEVs, while activated T-cells released SEVs and LEVs in considerably lower amounts. The release of SEVs from apoptotic T-cells was comparable with LEV release from activated ones. LEVs contained signaling proteins and proteins of the actin myosin cytoskeleton. SEVs carried cytoplasmic/endosomal proteins like the 70-kDa heat shock protein 70 (HSP70) or tumor susceptibility 101 (TSG101), microtubule associated proteins, and ubiquitinated proteins. The protein expression profile of SEVs and LEVs changed substantially after the induction of apoptosis. After apoptosis induction, HSP70 and TSG101 (often used as exosome markers) were highly expressed within LEVs. Interestingly, in contrast to HSP70 and TSG101, gelsolin and eps15 homology domain-containing protein 3 (EHD3) turned out to be specific for SEVs irrespective of the stimulus causing the EV release. Finally, we detected several subunits of the proteasome (PSMB9, PSMB10) as well as the danger signal HMGB1 exclusively within apoptotic cell-released LEVs. Thus, we were able to identify new marker proteins that can be useful to discriminate between distinct LEV subpopulations. The mass spectrometry proteomics data are available via ProteomeXchange with identifier PXD009074. PMID- 29599782 TI - C-Reactive Protein As a Mediator of Complement Activation and Inflammatory Signaling in Age-Related Macular Degeneration. AB - Age-related macular degeneration (AMD) is a devastating neurodegenerative disease affecting millions worldwide. Complement activation, inflammation, and the loss of choroidal endothelial cells have been established as key factors in both normal aging and AMD; however, the exact mechanisms for these events have yet to be fully uncovered. Herein, we provide evidence that the prototypic acute phase reactant, C-reactive protein (CRP), contributes to AMD pathogenesis. We discuss serum CRP levels as a risk factor for disease, immunolocalization of distinct forms of CRP in the at-risk and diseased retina, and direct effects of CRP on ocular tissue. Furthermore, we discuss the complement system as it relates to AMD pathophysiology, provide a model for the role of CRP in this disease, and outline current therapies being developed and tested to treat AMD patients. PMID- 29599786 TI - Coverage of Native Plants Is Key Factor Influencing the Invasibility of Freshwater Ecosystems by Exotic Plants in China. AB - Understanding the biotic and abiotic factors that influence the susceptibility of a community to invasion is beneficial for the prediction and management of invasive species and the conservation of native biodiversity. However, the relationships between factors and invasibility of a community have not been fully confirmed, and the factors most associated with the susceptibility of a community to invasion have rarely been identified. In this study, we investigated the species richness patterns in aquatic exotic and native plants and the relationships of exotic species richness with habitat and water environment factors in 262 aquatic plant communities in China. A total of 11 exotic plant species were recorded in our field survey, and we found neither a negative nor a positive relationship between aquatic exotic and native plant species richness. The aquatic exotic plant species richness is negatively correlated with the relative coverage and biomass of native plants but positively correlated with the total nitrogen (TN), total phosphorus (TP), and chemical oxygen demand (COD) concentrations in the water. The native plant species richness, native species' relative coverage, and native species' biomass were positively related to each other, whereas the TP, TN, and COD were also positively related to each other. The native plant species richness, native species' relative coverage, and native species biomass were each negatively correlated with the TP, TN, and COD. In addition, biotic rather than abiotic predictors accounted for most of the variation in exotic plant richness. Our results suggest that improving the vegetation coverage and the biodiversity of native plants is the most effective approach for preventing alien plant invasions and minimizing their impacts on freshwater ecosystems. PMID- 29599784 TI - Disease Evolution and Response to Rapamycin in Activated Phosphoinositide 3 Kinase delta Syndrome: The European Society for Immunodeficiencies-Activated Phosphoinositide 3-Kinase delta Syndrome Registry. AB - Activated phosphoinositide 3-kinase (PI3K) delta Syndrome (APDS), caused by autosomal dominant mutations in PIK3CD (APDS1) or PIK3R1 (APDS2), is a heterogeneous primary immunodeficiency. While initial cohort-descriptions summarized the spectrum of clinical and immunological manifestations, questions about long-term disease evolution and response to therapy remain. The prospective European Society for Immunodeficiencies (ESID)-APDS registry aims to characterize the disease course, identify outcome predictors, and evaluate treatment responses. So far, 77 patients have been recruited (51 APDS1, 26 APDS2). Analysis of disease evolution in the first 68 patients pinpoints the early occurrence of recurrent respiratory infections followed by chronic lymphoproliferation, gastrointestinal manifestations, and cytopenias. Although most manifestations occur by age 15, adult-onset and asymptomatic courses were documented. Bronchiectasis was observed in 24/40 APDS1 patients who received a CT-scan compared with 4/15 APDS2 patients. By age 20, half of the patients had received at least one immunosuppressant, but 2-3 lines of immunosuppressive therapy were not unusual before age 10. Response to rapamycin was rated by physician visual analog scale as good in 10, moderate in 9, and poor in 7. Lymphoproliferation showed the best response (8 complete, 11 partial, 6 no remission), while bowel inflammation (3 complete, 3 partial, 9 no remission) and cytopenia (3 complete, 2 partial, 9 no remission) responded less well. Hence, non-lymphoproliferative manifestations should be a key target for novel therapies. This report from the ESID-APDS registry provides comprehensive baseline documentation for a growing cohort that will be followed prospectively to establish prognostic factors and identify patients for treatment studies. PMID- 29599785 TI - CD1d-Restricted Type II NKT Cells Reactive With Endogenous Hydrophobic Peptides. AB - NKT cells belong to a distinct subset of T cells that recognize hydrophobic antigens presented by major histocompatibility complex class I-like molecules, such as CD1d. Because NKT cells stimulated by antigens can activate or suppress other immunocompetent cells through an immediate production of a large amount of cytokines, they are regarded as immunological modulators. CD1d-restricted NKT cells are classified into two subsets, namely, type I and type II. CD1d restricted type I NKT cells express invariant T cell receptors (TCRs) and react with lipid antigens, including the marine sponge-derived glycolipid alpha galactosylceramide. On the contrary, CD1d-restricted type II NKT cells recognize a wide variety of antigens, including glycolipids, phospholipids, and hydrophobic peptides, by their diverse TCRs. In this review, we focus particularly on CD1d restricted type II NKT cells that recognize endogenous hydrophobic peptides presented by CD1d. Previous studies have demonstrated that CD1d-restricted type I NKT cells usually act as pro-inflammatory cells but sometimes behave as anti inflammatory cells. It has been also demonstrated that CD1d-restricted type II NKT cells play opposite roles to CD1d-restricted type I NKT cells; thus, they function as anti-inflammatory or pro-inflammatory cells depending on the situation. In line with this, CD1d-restricted type II NKT cells that recognize type II collagen peptide have been demonstrated to act as anti-inflammatory cells in diverse inflammation-induction models in mice, whereas pro-inflammatory CD1d restricted type II NKT cells reactive with sterol carrier protein 2 peptide have been demonstrated to be involved in the development of small vessel vasculitis in rats. PMID- 29599787 TI - Yield Potential of Sugar Beet - Have We Hit the Ceiling? AB - The yield of sugar beet has continuously increased in the past decades. The question arises, whether this progress will continue in the future. A key factor for increasing yield potential of the crop is breeding progress. It was related to a shift in assimilate partitioning in the plant toward more storage carbohydrates (sucrose), whereas structural carbohydrates (leaves, cell wall compounds) unintendedly declined. The yield potential of sugar beet was estimated at 24 t sugar ha-1. For maximum yield, sufficient growth factors have to be available and the crop has to be able to fully utilize them. In sugar beet, limitations result from the lacking coincidence of maximum irradiation rates and full canopy cover, sink strength for carbon assimilation and high water demand, which cannot be met by rainfall alone. After harvest, sugar losses during storage occur. The paper discusses options for a further increase in yield potential, like autumn sowing of sugar beet, increasing sink strength and related constraints. It is prospected that yield increase by further widening the ratio of storage and structural carbohydrates will come to its natural limit as a certain cell wall stability is necessary. New challenges caused by climate change and by prolonged processing campaigns will occur. Thus breeding for improved pathogen resistance and storage properties will be even more important for successful sugar beet production than a further increase in yield potential itself. PMID- 29599783 TI - Metabolic Adaptations of CD4+ T Cells in Inflammatory Disease. AB - A controlled and self-limiting inflammatory reaction generally results in removal of the injurious agent and repair of the damaged tissue. However, in chronic inflammation, immune responses become dysregulated and prolonged, leading to tissue destruction. The role of metabolic reprogramming in orchestrating appropriate immune responses has gained increasing attention in recent years. Proliferation and differentiation of the T cell subsets that are needed to address homeostatic imbalance is accompanied by a series of metabolic adaptations, as T cells traveling from nutrient-rich secondary lymphoid tissues to sites of inflammation experience a dramatic shift in microenvironment conditions. How T cells integrate information about the local environment, such as nutrient availability or oxygen levels, and transfer these signals to functional pathways remains to be fully understood. In this review, we discuss how distinct subsets of CD4+ T cells metabolically adapt to the conditions of inflammation and whether these insights may pave the way to new treatments for human inflammatory diseases. PMID- 29599788 TI - Viruses and Phytoparasitic Nematodes of Cicer arietinum L.: Biotechnological Approaches in Interaction Studies and for Sustainable Control. AB - Cicer arietinum L. (chickpea) is the world's fourth most widely grown pulse. Chickpea seeds are a primary source of dietary protein for humans, and chickpea cultivation contributes to biological nitrogen fixation in the soil, given its symbiotic relationship with rhizobia. Therefore, chickpea cultivation plays a pivotal role in innovative sustainable models of agro-ecosystems inserted in crop rotation in arid and semi-arid environments for soil improvement and the reduction of chemical inputs. Indeed, the arid and semi-arid tropical zones of Africa and Asia have been primary areas of cultivation and diversification. Yet, nowadays, chickpea is gaining prominence in Canada, Australia, and South America where it constitutes a main ingredient in vegetarian and vegan diets. Viruses and plant parasitic nematodes (PPNs) have been considered to be of minor and local impact in primary areas of cultivation. However, the introduction of chickpea in new environments exposes the crop to these biotic stresses, compromising its yields. The adoption of high-throughput genomic technologies, including genome and transcriptome sequencing projects by the chickpea research community, has provided major insights into genome evolution as well as genomic architecture and domestication. This review summarizes the major viruses and PPNs that affect chickpea cultivation worldwide. We also present an overview of the current state of chickpea genomics. Accordingly, we explore the opportunities that genomics, post-genomics and novel editing biotechnologies are offering in order to understand chickpea diseases and stress tolerance and to design innovative control strategies. PMID- 29599789 TI - Simultaneous Improvement and Genetic Dissection of Drought Tolerance Using Selected Breeding Populations of Rice. AB - Drought is the most important factor limiting rice yield in most rainfed areas of Asia and Africa. Four large BC2F2 populations consisted of 3,200 individuals, which were derived from crosses between an elite Geng variety, Jigeng88, and four donors from three different countries, were screened and progeny tested under severe drought stress, resulting in the development of 72 introgression lines (ILs) with significantly improved yield compared to the recurrent parent Jigeng88. These DT ILs plus four random populations (without drought selection population) from the same crosses were evaluated in replicated trials under both drought stress and non-stress conditions in two environments, and characterized with simple sequence repeat (SSR) markers to understand how directional selection was operating on the genetic variation of DT of rice. Thirteen DT QTLs of large effect were identified based on the significant allelic and genotypic frequency shits in the DT ILs by using the joint segregation distortion method. The 13 QTLs were validated by the genotypic differences at individual QTL in the random populations. Putative genetic networks consisting of 30 loci in 29 functional genetic units underlying DT were detected by X2 tests and non-random associations between or among DT loci in DT ILs from the four populations. Most large-effect DT QTLs were previously reported and located in the upstream of the genetic networks as putative regulators, and were either mapped to important regulatory genes for DT or drought responsiveness reported previously. In our study, five promising ILs with significantly improved yield were selected under both drought and normal irrigated conditions. The QTLs and their genetic networks underlying DT detected provided useful genetic information for further improving DT and yield using designed QTL pyramiding. PMID- 29599790 TI - An Updated Functional Annotation of Protein-Coding Genes in the Cucumber Genome. AB - Background: Although the cucumber reference genome and its annotation were published several years ago, the functional annotation of predicted genes, particularly protein-coding genes, still requires further improvement. In general, accurately determining orthologous relationships between genes allows for better and more robust functional assignments of predicted genes. As one of the most reliable strategies, the determination of collinearity information may facilitate reliable orthology inferences among genes from multiple related genomes. Currently, the identification of collinear segments has mainly been based on conservation of gene order and orientation. Over the course of plant genome evolution, various evolutionary events have disrupted or distorted the order of genes along chromosomes, making it difficult to use those genes as genome-wide markers for plant genome comparisons. Results: Using the localized LASTZ/MULTIZ analysis pipeline, we aligned 15 genomes, including cucumber and other related angiosperm plants, and identified a set of genomic segments that are short in length, stable in structure, uniform in distribution and highly conserved across all 15 plants. Compared with protein-coding genes, these conserved segments were more suitable for use as genomic markers for detecting collinear segments among distantly divergent plants. Guided by this set of identified collinear genomic segments, we inferred 94,486 orthologous protein coding gene pairs (OPPs) between cucumber and 14 other angiosperm species, which were used as proxies for transferring functional terms to cucumber genes from the annotations of the other 14 genomes. In total, 10,885 protein-coding genes were assigned Gene Ontology (GO) terms which was nearly 1,300 more than results collected in Uniprot-proteomic database. Our results showed that annotation accuracy would been improved compared with other existing approaches. Conclusions: In this study, we provided an alternative resource for the functional annotation of predicted cucumber protein-coding genes, which we expect will be beneficial for the cucumber's biological study, accessible from http://cmb.bnu.edu.cn/functional_annotation. Meanwhile, using the cucumber reference genome as a case study, we presented an efficient strategy for transferring gene functional information from previously well-characterized protein-coding genes in model species to newly sequenced or "non-model" plant species. PMID- 29599792 TI - Plant and Floret Growth at Distinct Developmental Stages During the Stem Elongation Phase in Wheat. AB - Floret development is critical for grain setting in wheat (Triticum aestivum), but more than 50% of grain yield potential (based on the maximum number of floret primordia) is lost during the stem elongation phase (SEP, from the terminal spikelet stage to anthesis). Dynamic plant (e.g., leaf area, plant height) and floret (e.g., anther and ovary size) growth and its connection with grain yield traits (e.g., grain number and width) are not clearly understood. In this study, for the first time, we dissected the SEP into seven stages to investigate plant (first experiment) and floret (second experiment) growth in greenhouse- and field grown wheat. In the first experiment, the values of various plant growth trait indices at different stages were generally consistent between field and greenhouse and were independent of the environment. However, at specific stages, some traits significantly differed between the two environments. In the second experiment, phenotypic and genotypic similarity analysis revealed that grain number and size corresponded closely to ovary size at anthesis, suggesting that ovary size is strongly associated with grain number and size. Moreover, principal component analysis (PCA) showed that the top six principal components PCs explained 99.13, 98.61, 98.41, 98.35, and 97.93% of the total phenotypic variation at the green anther, yellow anther, tipping, heading, and anthesis stages, respectively. The cumulative variance explained by the first PC decreased with floret growth, with the highest value detected at the green anther stage (88.8%) and the lowest at the anthesis (50.09%). Finally, ovary size at anthesis was greater in wheat accessions with early release years than in accessions with late release years, and anther/ovary size shared closer connections with grain number/size traits at the late vs. early stages of floral development. Our findings shed light on the dynamic changes in plant and floret growth-related traits in wheat and the effects of the environment on these traits.

AB - Microelement contents and metabolism are vitally important for cereal plant growth and development as well as end-use properties. While minerals phytotoxicity harms plants, microelement deficiency also affects human health. Genetic engineering provides a promising way to solve these problems. As plants vary in abilities to uptake, transport, and accumulate minerals, and the key enzymes acting on that process is primarily presented in this review. Subsequently, microelement function and biosafety assessment of transgenic cereal plants have become a key issue to be addressed. Progress in genetic engineering of cereal plants has been made with the introduction of quality, high-yield, and resistant genes since the first transgenic rice, corn, and wheat were born in 1988, 1990, and 1992, respectively. As the biosafety issue of transgenic cereal plants has now risen to be a top concern, many studies on transgenic biosafety have been carried out. Transgenic cereal biosafety issues mainly include two subjects, environmental friendliness and end-use safety. Different levels of gene confirmation, genomics, proteomics, metabolomics and nutritiomics, absorption, metabolism, and function have been investigated. Also, the different levels of microelement contents have been measured in transgenic plants. Based on the motivation of the requested biosafety, systematic designs, and analysis of transgenic cereal are also presented in this review paper. PMID- 29599793 TI - Utilization of a Wheat55K SNP Array for Mapping of Major QTL for Temporal Expression of the Tiller Number. AB - Maximum tiller number and productive tiller number are important traits for wheat grain yield, but research involving the temporal expression of tiller number at different quantitative trait loci (QTL) levels is limited. In the present study, a population set of 371 recombined inbred lines derived from a cross between Chuan-Nong18 and T1208 was used to construct a high-density genetic map using a Wheat55K SNP Array and to perform dynamic QTL analysis of the tiller number at four growth stages. A high-density genetic map containing 11,583 SNP markers and 59 SSR markers that spanned 4,513.95 cM and was distributed across 21 wheat chromosomes was constructed. A total of 28 single environmental QTL were identified in the recombined inbred lines population, and among these, seven QTL were stable and used for multi-environmental and dynamic analysis. These QTL were mapped to chromosomes 2D, 4A, 4D, 5A, 5D, and 7D, respectively. Each QTL explained 1.63-21.22% of the observed phenotypic variation, with an additive effect from -20.51 to 11.59. Dynamic analysis showed that cqTN-2D.2 can be detected at four growth stages of tillering, explaining 4.92-17.16% of the observed phenotypic variations and spanning 13.71 Mb (AX-109283238-AX-110544009: 82189047-95895626) according to the physical location of the flanking markers. The effects of the stable QTL were validated in the recombined inbred lines population, and the beneficial alleles could be utilized in future marker assisted selection. Several candidate genes for MTN and PTN were predicted. The results provide a better understanding of the QTL selectively expressing the control of tiller number and will facilitate future map-based cloning. 9.17% SNP markers showed best hits to the Chinese Spring contigs. It was indicated that Wheat55K Array was efficient and valid to construct a high-density wheat genetic map. PMID- 29599794 TI - Groundwater Depth Affects Phosphorus But Not Carbon and Nitrogen Concentrations of a Desert Phreatophyte in Northwest China. AB - Ecological stoichiometry is an important aspect in the analysis of the changes in ecological system composition, structure, and function and understanding of plant adaptation in habitats. Leaf carbon (C), nitrogen (N), and phosphorus (P) concentrations in desert phreatophytes can be affected by different depths of groundwater through its effect on the adsorption and utilization of nutrient and plant biomass. We examined the biomass, soil organic C, available (mineral) N, and available P, and leaf C, N, and P concentrations of Alhagi sparsifolia grown at varying groundwater depths of 2.5, 4.5, and 11.0 m in 2015 and 2016 growing seasons in a desert-oasis ecotone in northwest China. The biomass of A. sparsifolia and the C, N, and P concentrations in soil and A. sparsifolia showed different responses to various groundwater depths. The leaf P concentration of A. sparsifolia was lower at 4.5 m than at 2.5 and 11.0 m likely because of a biomass dilution effect. By contrast, leaf C and N concentrations were generally unaffected by groundwater depth, thereby confirming that C and N accumulations in A. sparsifolia were predominantly determined by C fixation through the photosynthesis and biological fixation of atmospheric N2, respectively. Soil C, N, and P concentrations at 4.5 m were significantly lower than those at 11.0 m. Leaf P concentration was significantly and positively correlated with soil N concentration at all of the groundwater depths. The C:N and C:P mass ratios of A. sparsifolia at 4.5 m were higher than those at the other groundwater depths, suggesting a defensive life history strategy. Conversely, A. sparsifolia likely adopted a competitive strategy at 2.5 and 11.0 m as indicated by the low C:N and C:P mass ratios. To our knowledge, this study is the first to elucidate the variation in the C, N, and P stoichiometry of a desert phreatophyte at different groundwater depths in an arid ecosystem. PMID- 29599795 TI - Transcript Profiling Identifies NAC-Domain Genes Involved in Regulating Wall Ingrowth Deposition in Phloem Parenchyma Transfer Cells of Arabidopsis thaliana. AB - Transfer cells (TCs) play important roles in facilitating enhanced rates of nutrient transport at key apoplasmic/symplasmic junctions along the nutrient acquisition and transport pathways in plants. TCs achieve this capacity by developing elaborate wall ingrowth networks which serve to increase plasma membrane surface area thus increasing the cell's surface area-to-volume ratio to achieve increased flux of nutrients across the plasma membrane. Phloem parenchyma (PP) cells of Arabidopsis leaf veins trans-differentiate to become PP TCs which likely function in a two-step phloem loading mechanism by facilitating unloading of photoassimilates into the apoplasm for subsequent energy-dependent uptake into the sieve element/companion cell (SE/CC) complex. We are using PP TCs in Arabidopsis as a genetic model to identify transcription factors involved in coordinating deposition of the wall ingrowth network. Confocal imaging of pseudo Schiff propidium iodide-stained tissue revealed different profiles of temporal development of wall ingrowth deposition across maturing cotyledons and juvenile leaves, and a basipetal gradient of deposition across mature adult leaves. RNA Seq analysis was undertaken to identify differentially expressed genes common to these three different profiles of wall ingrowth deposition. This analysis identified 68 transcription factors up-regulated two-fold or more in at least two of the three experimental comparisons, with six of these transcription factors belonging to Clade III of the NAC-domain family. Phenotypic analysis of these NAC genes using insertional mutants revealed significant reductions in levels of wall ingrowth deposition, particularly in a double mutant of NAC056 and NAC018, as well as compromised sucrose-dependent root growth, indicating impaired capacity for phloem loading. Collectively, these results support the proposition that Clade III members of the NAC-domain family in Arabidopsis play important roles in regulating wall ingrowth deposition in PP TCs. PMID- 29599796 TI - Altered Tuber Yield in Genetically Modified High-Amylose and Oil Potato Lines Is Associated With Changed Whole-Plant Nitrogen Economy. AB - Breeding for improved crop quality traits can affect non-target traits related to growth and resource use, and these effects may vary in different cultivation conditions (e. g., greenhouse vs. field). The objectives of this study are to investigate the growth and whole-plant nitrogen (N) economy of two genetically modified (GM) potato lines compared to their non-GM parental varieties and when grown in different cultivation conditions. A high-amylose GM potato line and its parent were grown under field and greenhouse conditions for one growing season in Sweden; and a GM oil potato line and its parent were grown in greenhouse conditions only. Tuber yield, above ground biomass, N uptake efficiency and other plant N economy traits were assessed. In both cultivation conditions, the GM lines produced between 1.5 and two times more tubers as compared with their parents. In the greenhouse, fresh tuber yield and N uptake efficiency were unaffected by the genetic modifications, but the GM-lines produced less tuber biomass per plant-internal N compared to their parents. In the field, the fresh tuber yield was 40% greater in the high-amylose line as compared with its parent; the greater fresh tuber yield in the high-amylose GM line was accomplished by higher water allocation to the harvested tubers, and associated with increased N recovery from soil (+20%), N uptake efficiency (+53%), tuber N content (+20%), and N accumulation (+120%) compared with the non-GM parent. The cultivation conditions influenced the yield and N economy. For example, the final fresh above ground plant biomass and N pool were considerably higher in the greenhouse conditions, whilst the tuber yield was higher in the field conditions. In conclusion, the genetic modification inducing high accumulation of amylose in potato tubers affected several non-target traits related to plant N economy, and increased the plant N uptake and accumulation efficiency of the field-grown plants. Due to strongly increased plant N accumulation compared to the parental variety, the cultivation of the high-amylose line is expected to require higher N fertilization rates. However, starch productivity per unit land area or soil N still is expected to be higher in the high-amylose line. PMID- 29599797 TI - Activation of ROP6 GTPase by Phosphatidylglycerol in Arabidopsis. AB - Plant Rho-like GTPases (ROPs) are switch-like proteins which play essential roles in controlling cell polarity development and cellular activities. ROPs are regulated by many factors, such as auxin, light, and RopGEFs and RopGAPs proteins. However, it has not been reported yet whether small molecules play a role in the regulation of ROP activity. Here, we showed that AtROP6 specially bound to a phospholipid, phosphatidylglycerol (PG), by the protein-lipid overlay and liposome sedimentation assays, and further MST assay gave a dissociation constant (Kd) of 4.8 +/- 0.4 MUM for binding of PG to His-AtROP6. PG profile analysis in Arabidopsis revealed that PG existed both in leaves and roots but with distinctive fatty acyl chain patterns. By evaluating AtROP6 activity using RIC1 effector binding-based assay, we found that PG stimulated AtROP6 activity. In the FM4-64 uptake experiment, PG inhibited AtROP6-mediated endocytosis process. By evaluating internalization of PIN2, PG was shown to regulate endocytosis process coordinately with NAA. Further root gravitropism experiment revealed that PG enhanced the AtROP6-mediated root gravity response. These results suggest that the phospholipid PG physically binds AtROP6, stimulates its activity and influences AtROP6-mediated root gravity response in Arabidopsis. PMID- 29599798 TI - SNP Data Quality Control in a National Beef and Dairy Cattle System and Highly Accurate SNP Based Parentage Verification and Identification. AB - A major use of genetic data is parentage verification and identification as inaccurate pedigrees negatively affect genetic gain. Since 2012 the international standard for single nucleotide polymorphism (SNP) verification in Bos taurus cattle has been the ISAG SNP panels. While these ISAG panels provide an increased level of parentage accuracy over microsatellite markers (MS), they can validate the wrong parent at <=1% misconcordance rate levels, indicating that more SNP are needed if a more accurate pedigree is required. With rapidly increasing numbers of cattle being genotyped in Ireland that represent 61 B. taurus breeds from a wide range of farm types: beef/dairy, AI/pedigree/commercial, purebred/crossbred, and large to small herd size the Irish Cattle Breeding Federation (ICBF) analyzed different SNP densities to determine that at a minimum >=500 SNP are needed to consistently predict only one set of parents at a <=1% misconcordance rate. For parentage validation and prediction ICBF uses 800 SNP (ICBF800) selected based on SNP clustering quality, ISAG200 inclusion, call rate (CR), and minor allele frequency (MAF) in the Irish cattle population. Large datasets require sample and SNP quality control (QC). Most publications only deal with SNP QC via CR, MAF, parent-progeny conflicts, and Hardy-Weinberg deviation, but not sample QC. We report here parentage, SNP QC, and a genomic sample QC pipelines to deal with the unique challenges of >1 million genotypes from a national herd such as SNP genotype errors from mis-tagging of animals, lab errors, farm errors, and multiple other issues that can arise. We divide the pipeline into two parts: a Genotype QC and an Animal QC pipeline. The Genotype QC identifies samples with low call rate, missing or mixed genotype classes (no BB genotype or ABTG alleles present), and low genotype frequencies. The Animal QC handles situations where the genotype might not belong to the listed individual by identifying: >1 non matching genotypes per animal, SNP duplicates, sex and breed prediction mismatches, parentage and progeny validation results, and other situations. The Animal QC pipeline make use of ICBF800 SNP set where appropriate to identify errors in a computationally efficient yet still highly accurate method. PMID- 29599800 TI - Application of Synthetic Polymeric Scaffolds in Breast Cancer 3D Tissue Cultures and Animal Tumor Models. AB - Preparation of three-dimensional (3D) porous scaffolds from synthetic polymers is a challenge to most laboratories conducting biomedical research. Here, we present a handy and cost-effective method to fabricate polymeric hydrogel and porous scaffolds using poly(lactic-co-glycolic) acid (PLGA) or polycaprolactone (PCL). Breast cancer cells grown on 3D polymeric scaffolds exhibited distinct survival, morphology, and proliferation compared to those on 2D polymeric surfaces. Mammary epithelial cells cultured on PLGA- or PCL-coated slides expressed extracellular matrix (ECM) proteins and their receptors. Estrogen receptor- (ER-) positive T47D breast cancer cells are less sensitive to 4-hydroxytamoxifen (4-HT) treatment when cultured on the 3D porous scaffolds than in 2D cultures. Finally, cancer cell-laden polymeric scaffolds support consistent tumor formation in animals and biomarker expression as seen in human native tumors. Our data suggest that the porous synthetic polymer scaffolds satisfy the basic requirements for 3D tissue cultures both in vitro and in vivo. The scaffolding technology has appealing potentials to be applied in anticancer drug screening for a better control of the progression of human cancers. PMID- 29599799 TI - Peroxisome Proliferator-Activated Receptor gamma and PGC-1alpha in Cancer: Dual Actions as Tumor Promoter and Suppressor. AB - Peroxisome proliferator-activated receptor gamma (PPARgamma) is part of a nuclear receptor superfamily that regulates gene expression involved in cell differentiation, proliferation, immune/inflammation response, and lipid metabolism. PPARgamma coactivator-1alpha (PGC-1alpha), initially identified as a PPARgamma-interacting protein, is an important regulator of diverse metabolic pathways, such as oxidative metabolism and energy homeostasis. The role of PGC 1alpha in diabetes, neurodegeneration, and cardiovascular disease is particularly well known. PGC-1alpha is also now known to play important roles in cancer, independent of the role of PPARgamma in cancer. Though many researchers have studied the expression and clinical implications of PPARgamma and PGC-1alpha in cancer, there are still many controversies about the role of PPARgamma and PGC 1alpha in cancer. This review examines and summarizes some recent data on the role and action mechanisms of PPARgamma and PGC-1alpha in cancer, respectively, particularly the recent progress in understanding the role of PPARgamma in several cancers since our review was published in 2012. PMID- 29599801 TI - Continuous Flash Glucose Monitoring in children with Congenital Hyperinsulinism; first report on accuracy and patient experience. AB - Background: The factory calibrated FreeStyle Libre (FSL) flash glucose monitoring system has been recently introduced for use in patients with diabetes mellitus. There are no reports available regarding its use in patients with congenital hyperinsulinism (CHI). We have assessed the accuracy of FSL compared to the finger prick capillary blood glucose (CBG) over 2 weeks period in patients with CHI and evaluated the parents' experience of using FSL. Methods: Four hundred sixty-seven episodes of CBG along with corresponding swipe FSL readings were available from 11 children with CHI (0.5-5 years). A detailed questionnaire was completed by the parents. Results: The mean variation between the two methods was 0.29 mmol/l (SD +/-1.07), higher readings by FSL compared to CBG. The FSL sensors stayed in-situ for an average period of 11.5 days. There was a positive correlation between the two methods (r = 0.7). The FSL tended to overestimate compared to CBG (bias = 0.29 mmol/l; 95% CI: 0.19 to 0.38). Only 70% of values were within the reference standard (+/-0.83 mmol/l) at glucose concentrations less than 5.6 mmol/l. The overall Mean Absolute Relative Difference (MARD) was 17.9%. Forty two episodes of hypoglycaemia (CBG < 3.5 mmol/l) were noted but FSL identified only 52% of these episodes. The Bland Altman analysis showed the 95% limits of agreement between the two methods ranging from - 1.8 (95% CI: -1.97 to 1.64) to 2.37 (95% CI: 2.21 to 2.54). Majority of the parents found the glucose trend on FSL to be useful to detect and prevent hypoglycaemic episodes. All parents felt that FSL is a very easy and convenient method to measure the glucose especially during sleep. A significant proportion of parents felt that FSL readings were not accurate and 56% of parents expressed interest to continue using FSL after the trial period. Conclusion: Noticeable variability between the two methods of measuring the glucose was noted. Despite the ease of using the FSL system, concerns related to accuracy, especially at low glucose values do remain although parents find the glucose trend to be very useful. Further larger trials are needed in CHI patients before FSL is recommended as a routine alternative method for measuring glucose levels. PMID- 29599802 TI - Tuberculosis induced autoimmune haemolytic anaemia: a systematic review to find out common clinical presentations, investigation findings and the treatment options. AB - Background: Tuberculosis induced autoimmune haemolytic anaemia is a rare entity. The aim of this study was to explore its common presentations, investigation findings and treatment options through a systematic review of published reports. Methods: PubMed, Trip, Google Scholar, Science Direct, Cochrane Library, Open Grey, Grey literature report and the reference lists of the selected articles were searched for case reports in English on tuberculosis induced auto-immune haemolytic anaemia. PRISMA statement was used for systematic review. Quality assessment of the selected reports was done using the CARE guidelines. Results: Twenty-one articles out of 135 search results were included. Thirty-three percent of patients were reported from India. More than half had fever and pallor. The mean haemoglobin was 5.77 g/dl (SD 2.2). Positive direct coombs test was seen in all patients. Pulmonary tuberculosis (43%) was most prevalent. Twenty-nine percent of patients needed a combination of anti-tuberculosis medicines, blood transfusion and steroids. Higher percentage of disseminated TB induced AIHA (67%) needed steroids in comparison to the other types of TB induced AIHA (13%). Conclusions: Rarer complications of tuberculosis such as auto-immune haemolytic anaemia should be looked for especially in disease-endemic areas. Blood transfusion and steroids are additional treatment options along with the anti tuberculosis medicines. PMID- 29599803 TI - Neuroprotective Effects and Mechanism of beta-Asarone against Abeta1-42-Induced Injury in Astrocytes. AB - Emerging evidence suggests that activated astrocytes play important roles in AD, and beta-asarone, a major component of Acorus tatarinowii Schott, was shown to be a potential therapeutic candidate for AD. While our previous study found that beta-asarone could improve the cognitive function of rats hippocampally injected with Abeta, the effects of beta-asarone on astrocytes remain unclear, and this study aimed to investigate these effects. A rat model of Abeta1-42 (10 MUg) was established, and the rats were intragastrically treated with beta-asarone at doses of 10, 20, and 30 mg/kg or donepezil at a dose of 0.75 mg/kg. The sham and model groups were intragastrically injected with an equal volume of saline. Animals were sacrificed on the 28th day after administration of the drugs. In addition, a cellular model of Abeta1-42 (1.1 MUM, 6 h) was established, and cells were treated with beta-asarone at doses of 0, 2.06, 6.17, 18.5, 55.6, and 166.7 MUg/mL. beta-Asarone improved cognitive impairment, alleviated Abeta deposition and hippocampal damage, and inhibited GFAP, AQP4, IL-1beta, and TNF-alpha expression. These results suggested that beta-asarone could alleviate the symptoms of AD by protecting astrocytes, possibly by inhibiting TNF-alpha and IL 1beta secretion and then downregulating AQP4 expression. PMID- 29599804 TI - Metabolic Profiling Analysis of the Alleviation Effect of the Fractions of Niuhuang Jiedu Tablet on Realgar Induced Toxicity in Rats. AB - Niuhuang Jiedu Tablet (NJT) is a classical formula in treating acute tonsillitis, pharyngitis, and so on. In the formula, significant level of Realgar as a potentially toxic element is contained. Our previous experiments revealed that it was less toxic for combined Realgar in NJT. However, the active fraction of this prescription with toxicity alleviation effect on Realgar was still obscure. NJT was divided into five different polar fractions (NJT-PET, NJT-25, NJT-50, NJT-75, and NJT-95), and we explored the toxicity alleviation effect on Realgar. Based on 1H NMR spectra of urine and serum from rats, PCA and PLS-DA were performed to identify different metabolic profiles. Liver and kidney histopathology examinations and serum clinical chemistry analysis were also performed. With pattern recognition analysis of metabolites in urine and serum, Realgar group showed a clear separation from control group, while the metabolic profiles of NJT PET, NJT-25, NJT-50, and NJT-95 groups were similar to Realgar group, and the metabolic profiles of NJT and NJT-75 groups were very close to control group. Statistics results were confirmed by the histopathological examination and biochemical assay. The present work indicated that 75% EtOH fraction of NJT was the most valid fraction with the toxicity alleviation effect on Realgar. PMID- 29599805 TI - Qi-Dong-Huo-Xue-Yin Inhibits Inflammation in Acute Lung Injury in Mice via Toll Like Receptor 4/Caveolin-1 Signaling. AB - Acute lung injury (ALI) is a critical illness with no current effective treatment. Caveolin-1 indirectly activates inflammation-associated signaling pathways by inhibiting endothelial nitric oxide synthase (eNOS). This induces an imbalance between pro- and anti-inflammatory cytokine levels, which are involved in the pathogenesis of ALI. The compound Chinese prescription Qi-Dong-Huo-Xue-Yin (QDHXY) is efficacious for ALI treatment via an anti-inflammatory effect; however, the exact underlying mechanism is unknown. Therefore, we explored the protective effect of QDHXY against lipopolysaccharide- (LPS-) induced ALI in mice. Histopathological changes in mouse lung tissues were studied. Furthermore, alterations in the serum levels of pro- and anti-inflammatory cytokines were investigated. The levels of tumor necrosis factor- (TNF-)alpha, interleukin- (IL ) 6, IL-1beta, and interferon-gamma-induced protein 10 in bronchoalveolar lavage fluid were measured. Additionally, the expression levels of myeloid differentiation factor 88 (MyD88), caveolin-1, and eNOS were assessed. QDHXY significantly reduced lung infiltration with inflammatory cells and the production of serum pro- and anti-inflammatory cytokines and inhibited the expression of TNF-alpha, IL-1beta, caveolin-1, and MyD88 but not eNOS. These indicate that QDHXY significantly improved the balance between pro- and anti inflammatory cytokine levels, possibly by inhibiting the caveolin-1 signaling pathway. Therefore, QDHXY may be a potential treatment for ALI. PMID- 29599806 TI - WenTong HuoXue Cream Can Inhibit the Reduction of the Pain-Related Molecule PLC beta3 in the Dorsal Root Ganglion of a Rat Model of Diabetic Peripheral Neuropathy. AB - WenTong HuoXue Cream (WTHX-Cream) has been shown to effectively alleviate clinical symptoms of diabetic peripheral neuropathy (DPN). This study investigated the gene and protein expression of the pain-related molecule PLC beta3 in the dorsal root ganglion (DRG) of DPN rats. 88 specific pathogen-free male Wistar rats were randomly divided into placebo (10 rats) and DPN model (78 rats) groups, and the 78 model rats were used to establish the DPN model by intraperitoneal injection of streptozotocin and were then fed a high-fat diet for 8 weeks. These rats were randomly divided into the model group, the high-, medium , and low-dose WTHX-Cream + metformin groups, the metformin group, the capsaicin cream group, and the capsaicin cream + metformin group. After 4 weeks of continuous drug administration, the blood glucose, body weight, behavioral indexes, and sciatic nerve conduction velocity were measured. The pathological structure of the DRG and the sciatic nerve were observed. PLC-beta3 mRNA and protein levels in the DRG of rats were measured. Compared with the model group, the high-dose WTHX-Cream group showed increased sciatic nerve conduction velocity, improved sciatic nerve morphological changes, and increased expression of PLC-beta3 mRNA and protein in the DRG. This study showed that WTHX-Cream improves hyperalgesia symptoms of DPN by inhibiting the reduction of PLC-beta3 mRNA and protein expression in the diabetic DRG of DPN rats. PMID- 29599807 TI - Analgesic and Anti-Inflammatory Activities of Diethyl Ether and n-Hexane Extract of Polyalthia suberosa Leaves. AB - In folk medicine, Polyalthia suberosa is used as abortifacient, laxative, febrifuge analgesic, filler of tooth cavities, and anti-HIV drug and for rheumatism and various skin infections. The present study was directed to evaluate the analgesic and anti-inflammatory activities of diethyl ether and n hexane extracts of Polyalthia suberosa leaves (PSDE and PSNH). A variety of tests including formalin-induced paw licking test, acetic acid induced writhing test, and tail immersion test were used to assess the analgesic activity. In addition, xylene-induced ear edema test was used to evaluate anti-inflammatory activity of PSDE and PSNH. PSDE and PSNH at 200 and 400 mg/kg doses expressed analgesic as well as anti-inflammatory activities in mice. In formalin-induced paw licking test, acetic acid induced writhing test, and xylene-induced ear edema test, the extracts exhibited significant inhibition (*P < 0.05 versus control) of pain and inflammation. Alternatively, in tail immersion test, PSDE 400 mg/kg showed significant (*P < 0.05 versus control) latency at 30 min but another tested sample had no significant latency. From this study, it could be shown that Polyalthia suberosa leaves may contain analgesic and anti-inflammatory agents which support its use in traditional medicine. PMID- 29599808 TI - Evidence-Based Study to Compare Daodi Traditional Chinese Medicinal Material and Non-Daodi Traditional Chinese Medicinal Material. AB - Background: Daodi medicinal material is widely used in Chinese herb medication. However, there is a lack of systematic methodology for identifying characteristics associated with good quality and reliable efficacy of Daodi med material. Purpose: The purpose of this study is to provide some evidence to further substantiate the use of Daodi medicinal materials. Methods: Seven relevant databases were searched before July 2014. Two evaluators were responsible for screening and categorizing the results. The data was analyzed with Microsoft Excel 2007 and SPSS 21.0 statistical software. Results: Overall, 107 articles were systematically analyzed. Of these studies, 55.1% (59/107) focused on the methodology to assess Daodi med-material, and 38.3% (41/107) were interested in med-material ingredients, soil physical and chemical properties, and the geological background system (GBS). Only 6.5% (7/107) of studies were mainly conducted as clinical trials and animal experiments. Conclusion: Comparisons between Daodi and non-Daodi materials have been studied mainly in terms of the ingredients or composition of medical materials, soil physics and chemistry, and the GBS, and some identifying methodologies have been created to identify Daodi attributes. Until now, there is still no consensus of comparison criteria between Daodi and non-Daodi medicinal material. Only a few studies were conducted through animal experiments and clinical trials to determine Daodi superiority. PMID- 29599809 TI - Electroacupuncture at ST36 Increases Bone Marrow-Derived Interstitial Cells of Cajal via the SDF-1/CXCR4 and mSCF/Kit-ETV1 Pathways in the Stomach of Diabetic Mice. AB - Background: The loss of interstitial cells of Cajal (ICC) is observed in diabetic gastroparesis. Electroacupuncture (EA) maintains ICC networks, but the effects and mechanisms of EA on ICC of bone marrow derivation in the stomach have not been investigated. Methods: C57BL/6 mice were randomized into six groups: control, diabetic (DM), bone marrow transplantation (BMT) + DM, BMT + DM + sham EA (SEA), BMT + DM + low-frequency EA (LEA), and BMT + DM + high-frequency (HEA). c-Kit+GFP+ cells in the stomach were detected by immunofluorescence staining. Western blotting and qRT-PCR were employed to determine c-Kit, GFP, SDF-1, CXCR4, mSCF, pERK, and ETV1 expression. Results: (1) c-Kit+GFP+ cells were elevated in the BMT + DM + LEA and HEA groups. (2) The mRNA and protein levels of GFP, SDF-1, and CXCR4 were increased in the BMT + DM + LEA and BMT + DM + HEA groups. (3) The mRNA and protein levels of mSCF, c-Kit, pERK, and ETV1 were significantly reduced in the DM group but markedly elevated in the BMT + DM + LEA and HEA groups. Conclusion: EA at ST36 increases bone marrow-derived ICC in the stomach of diabetic mice via the SDF-1/CXCR4 and mSCF/c-Kit-ETV1 pathways. PMID- 29599810 TI - The Aqueous Extract of Gynura divaricata (L.) DC. Improves Glucose and Lipid Metabolism and Ameliorates Type 2 Diabetes Mellitus. AB - Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by hyperglycemia and dyslipidemia caused by impaired insulin secretion and resistance of the peripheral tissues. A major pathogenesis of T2DM is obesity associated insulin resistance. Gynura divaricata (L.) DC. (GD) is a natural plant and has been reported to have numerous health-promoting effects on both animals and humans. In this study, we aimed to elucidate the regulatory mechanism of GD improving glucose and lipid metabolism in an obesity animal model induced by high fat and high-sugar diet in combination with low dose of streptozocin and an insulin-resistant HepG2 cell model induced by dexamethasone. The study showed that the water extract of GD (GD extract A) could significantly reduce fasting serum glucose, reverse dyslipidemia and pancreatic damage, and regulate the body weight of mice. We also found that GD extract A had low toxicity in vivo and in vitro. Furthermore, GD extract A may increase glucose consumption in insulin resistant HepG2 cells, markedly inhibit NF-kappaB activation, and decrease the impairment in signaling molecules of insulin pathway, such as IRS-1, AKT, and GLUT1. Overall, the results indicate that GD extract A is a promising candidate for the prevention and treatment of T2DM.

AB - Introduction: This study aims to investigate the clinical practice states on the diagnosis and treatment for insomnia between Korean medical general practitioners (KMGPs) and Korean medical neuropsychiatry specialists (KMNPSs). Methods: We distributed questionnaires via email or in person to 1,017 KMGPs and via email to 165 KMNPSs. We collected and analyzed responses from 305 (30.00%) KMGPs and 53 (32.12%) KMNPSs. Results: Most KMGPs and KMNPSs responded that the number of new patients visiting the clinic for treatment of insomnia was less than 10 per month (78.2%). Frequently utilized therapies for insomnia are acupuncture and herbal decoctions. Particularly acupoint GV20 and Guipi decoction were chosen with the highest response rate. There was no difference between KMNPSs and KMGPs in the traditional Korean medical diagnosis methods. However, KMNPSs utilized more various methods to diagnose, treat, and evaluate insomnia and educated more actively sleep hygiene compared to KMGPs. Conclusions: This survey showed how insomnia is currently diagnosed and treated in Korean medical care settings. Moreover, we identified some differences between KMNPSs and KMGPs. Further research is required to explore the underlying reasons for these discrepancies among KMDs and to improve the quality of Korean medical clinical practice in treating insomnia. PMID- 29599812 TI - Study of Pharmacodynamic and Pharmacokinetic Interaction of Bojungikki-Tang with Aspirin in Healthy Subjects and Ischemic Stroke Patients. AB - Background: Bojungikki-tang (BJIKT) is a widely used traditional herbal formula in China, Japan, and Korea. There have been reports that several herbs among BJIKT have interactions with antiplatelet drugs, such as aspirin. This study aimed to assess whether BJIKT interacts with aspirin in terms of pharmacokinetics (PK) and pharmacodynamics (PD) in healthy subjects and ischemic stroke patients. Methods: The phase I interaction trial was a randomized, open-label, crossover study of 10 healthy male subjects, and the phase III interaction trial was a randomized, placebo-controlled, parallel study of 43 ischemic stroke patients. Each participant randomly received aspirin + BJIKT or aspirin + placebo. For PK analysis, plasma acetyl salicylic acid (ASA) and salicylic acid (SA) were evaluated, and, for PD analysis, platelet aggregation and plasma thromboxane B2 (TxB2) were measured. Results: In the PK parameters, mean area under curve, maximum concertation, and peak concentration time of ASA and SA were not different between two groups in healthy subjects and ischemic stroke patients. In the PD profiles, TxB2 concentrations and platelet aggregation were not affected by coadministration of BJIKT in healthy subjects and ischemic stroke patients. Conclusions: These results suggest that coadministration of BJIKT with aspirin may not result in herb-drug interaction. PMID- 29599813 TI - Cytopathologist-performed and ultrasound-guided fine needle aspiration cytology enhances diagnostic accuracy and avoids pitfalls: An overview of 20 years of personal experience with a selection of didactic cases. AB - Over the last few decades, fine needle aspiration cytology (FNA) has emerged as a SAFE (Simple, Accurate, Fast, Economical) diagnostic tool based on the morphologic evaluation of cells. The first and most important step in obtaining accurate results from FNA is to procure sufficient and representative material from the lesion and to appropriately transfer this material to the laboratory. Unfortunately, the most important aspect of this task occurs beyond the control of the cytopathologist, a key reason for obtaining unsatisfactory results with FNA. There is growing interest in the field of cytology in "cytopathologist performed ultrasound (US)-guided FNA," which has been reported to yield accurate results. The first author has been applying FNA in his own private cytopathology practice with a radiologist and under the guidance of US for more than 20 years. This study retrospectively reviews the utility of this practice. We present a selection of didactic examples under different headings that highlight the application of FNA by a cytopathologist, accompanied by US, under the guidance of a radiologist, in the form of an "outpatient FNA clinic." The use of this technique enhances diagnostic accuracy and prevents pitfalls. The highlights of each case are also outlined as "take-home messages."

AB - Background: Accurate and automated phenotyping of leaf images is necessary for high throughput studies of leaf form like genome-wide association analysis and other forms of quantitative trait locus mapping. Dissected leaves (also referred to as compound) that are subdivided into individual units are an attractive system to study diversification of form. However, there are only few software tools for their automated analysis. Thus, high-throughput image processing algorithms are needed that can partition these leaves in their phenotypically relevant units and calculate morphological features based on these units. Results: We have developed MowJoe, an image processing algorithm that dissects a dissected leaf into leaflets, petiolule, rachis and petioles. It employs image skeletonization to convert leaves into graphs, and thereafter applies algorithms operating on graph structures. This partitioning of a leaf allows the derivation of morphological features such as leaf size, or eccentricity of leaflets. Furthermore, MowJoe automatically places landmarks onto the terminal leaflet that can be used for further leaf shape analysis. It generates specific output files that can directly be imported into downstream shape analysis tools. We applied the algorithm to two accessions of Cardamine hirsuta and show that our features are able to robustly discriminate between these accessions. Conclusion: MowJoe is a tool for the semi-automated, quantitative high throughput shape analysis of dissected leaf images. It provides the statistical power for the detection of the genetic basis of quantitative morphological variations.

AB - Background: To improve acute trauma care workflow, the number of trauma centers equipped with a computed tomography (CT) machine in the trauma resuscitation room has increased. The effect of the presence of a CT machine in the trauma room on a patient's outcome is still unclear. This study evaluated the association between a CT machine in the trauma room and a patient's outcome. Methods: Our study included all trauma patients admitted to a trauma center in Yokohama, Japan, between April 2014 and March 2016. We compared 140 patients treated using a conventional resuscitation room with 106 patients treated in new trauma rooms equipped with a CT machine. Results: For the group treated in a trauma room with a CT machine, the Injury Severity Score (13.0 vs. 9.0; p = 0.002), CT scans of the head (78.3 vs. 66.4%; p = 0.046), CT scans of the body trunk (75.5 vs. 58.6%; p = 0.007), intubation in the emergency department (48.1 vs. 30.7%; p = 0.008), and multiple trauma patients (47.2 vs. 30.0%; p = 0.008) were significantly higher and Trauma and Injury Severity Score probability of survival (96.75 vs. 97.80; p = 0.009) was significantly lower than the group treated in a conventional resuscitation room. In multivariate analysis and propensity score matched analysis, being treated in a trauma room with a CT machine was an independent predictor for fewer hospital deaths (odds ratio 0.002; 95% CI 0.00 0.75; p = 0.04, and 0.07; 0.00-0.98, respectively). Conclusions: Equipping a trauma room with a CT machine reduced the time in decision-making for treating a trauma patient and subsequently lowered the mortality of trauma patients. PMID- 29599817 TI - Wenyang Huazhuo Tongluo formula inhibits fibrosis via suppressing Wnt/beta catenin signaling pathway in a Bleomycin-induced systemic sclerosis mouse model. AB - Background: Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs. So far, no Western medicine treatment can completely inhibit or reverse the progress of SSc, while at the same time, our previous series of studies have shown that the treatment of SSc by the Wenyang Huazhuo Tongluo formula (WYHZTL), a Chinese herbal decoction, shows a delightful prospect. The aim of this study is to further investigate the mechanism of anti-fibrosis of WYHZTL formula in SSc mouse model. Methods: The Bleomycin-induced SSc mouse model was treated with saline (BLM), high-dosage of WYHZTL formula (WYHZTL-H), medium-dosage of WYHZTL formula (WYHZTL-M), low-dosage of WYHZTL formula (WYHZTL-L) and XAV-939, a small molecule inhibitor of Wnt/beta catenin signaling pathway, by the intragastric administration and intraperitoneal injection, respectively. The mRNA and protein levels of Wnt/beta-catenin signaling pathway associated genes, fibrosis markers and histopathology were detected by reverse transcription-quantitative polymerase chain reaction, Western blotting and hematoxylin/eosin-staining. The levels of Wnt1, CTGF and DKK1 protein in serum were detected by enzyme-linked immunosorbent assay. Results: Compared with BLM group, the WYHZTL formula and XAV-939 could significantly inhibit the thickness of the skin tissue of the SSc mouse model. The mRNA expression levels of GSK3beta and DKK1 in the WYHZTL formula and XAV-939-treated group were significantly higher than those in the BLM group, while Wnt1, beta catenin, TCF4, cyclin D1, survivin, VEGF, CTGF, FN1, collagen I/III were decreased. Compared with BLM group, the protein expression levels of GSK3beta and DKK1 in the WYHZTL formula and XAV-939-treated group were upregulated, while Wnt1, beta-catenin, cyclin D1, survivin, CTGF, FN1, collagen I/III were downregulated. WYHZTL formula and XAV-939 could inhibit expression of Wnt1 and CTGF, but promoted DKK1 in serum. Furthermore, WYHZTL-H seemed more effective than WYHZTL-M and/or XAV-939 on regulating Wnt1, beta-catenin, TCF4, GSK3beta, DKK1, cyclin D1, survivin, VEGF, CTGF, FN1 and collagen I/III. Conclusion: This present study demonstrates that WYHZTL formula has anti-fibrosis effect in Bleomycin-induced SSc mouse model in a dosage-dependent manner, and the molecular mechanism may be related to the inhibition of Wnt/beta-catenin signaling pathway. PMID- 29599818 TI - Cellular prognostic markers in hepatitis-related hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and accounts for about 6% of all new cancers diagnosed worldwide. Moreover, it is the third and the fifth leading cause of death from cancer in men and women, respectively. HBV and HCV chronic infection is the main risk factor for HCC. A range of therapies are used in the management of HCC according to the extent and severity of liver disease. In this perspective, evaluation of prognosis represents a crucial step for proper management of HCC patients. However, the clinical outcome can be significantly different in HCC patients within the same stage of disease. Therefore, many efforts have been made to define new parameters with more precise prognostic value, and the search for HCC prognostic markers is gaining momentum. The present review aims at providing an update on cellular prognostic markers for HCC. PMID- 29599819 TI - The new WHO decision-making framework on vaccine use in acute humanitarian emergencies: MSF experience in Minkaman, South Sudan. AB - Introduction: The main causes of death during population movements can be prevented by addressing the population's basic needs. In 2013, the World Health Organization (WHO) issued a framework for decision making to help prioritize vaccinations in acute humanitarian emergencies. This article describes MSF's experience of applying this framework in addition to addressing key population needs in a displacement setting in Minkaman, South Sudan. Case description: Military clashes broke out in South Sudan in December 2013. By May 2014, Minkaman, a village in the Lakes State, hosted some 85,000 displaced people. MSF arrived in Minkaman on 28 December 2013 and immediately provided interventions to address the key humanitarian needs (health care, access to drinking water, measles vaccination). The WHO framework was used to identify priority vaccines: those preventing outbreaks (measles, polio, oral cholera vaccine, and vaccine against meningococcal meningitis A (MenAfrivac(r))) and those reducing childhood morbidity and mortality (pentavalent vaccine that combines diphtheria, tetanus, whooping cough, hepatitis B, and Haemophilus influenzae type B; pneumococcal vaccine; and rotavirus vaccine). By mid-March, access to primary and secondary health care was ensured, including community health activities and the provision of safe water. Mass vaccination campaigns against measles, polio, cholera, and meningitis had been organized. Vaccination campaigns against the main deadly childhood diseases, however, were not in place owing to lack of authorization by the Ministry of Health (MoH). Conclusions: The first field use of the new WHO framework for prioritizing vaccines in acute emergencies is described. Although MSF was unable to implement the full package of priority vaccines because authorization could not be obtained from the MoH, a series of mass vaccination campaigns against key epidemic-prone diseases was successfully implemented within a complex emergency context. Together with covering the population's basic needs, this might have contributed to reducing mortality levels below the emergency threshold and to the absence of epidemics. For the WHO framework to be used to its full potential it must not only be adapted for field use but, most importantly, national decision makers should be briefed on the framework and its practical implementation. PMID- 29599820 TI - A structured approach to integrating mental health services into primary care: development of the Mental Health Scale Up Nigeria intervention (mhSUN). AB - Background: The treatment gap for mental illness in Nigeria, as in other sub Saharan countries, is estimated to be around 85%. There is need to prioritise mental health care in low and middle income countries by providing a strong body of evidence for effective services, particularly with a view to increasing international and government confidence in investment in scaling up appropriate services. This paper lays out the processes by which a programme to integrate evidence-based mental health care into primary care services in Nigeria was designed, including a research framework to provide evidence from a robust evaluation. Methods: This paper forms the first step in the overall process evaluation of the mhSUN intervention, where standard research practice indicates that the intervention, and its development, is clearly documented prior to subsequent evaluation. The report covers the period of programme development and evaluation design, and study site and design was chosen to allow generalisability and practical conclusions to be drawn for service development in Nigeria. In order to design an intervention that was informed by evidence and took into account local context and input of stakeholders, a structured process was followed, including: (1) Engagement of relevant stakeholders for information gathering and buy-in; (2) Literature review and gathering of pertinent evidence; (3) Situation analysis at a national and local level; (4) Model development (using Theory of Change); (5) Ongoing consultation, recognising the iterative nature of Theory of Change, and need for ongoing refinement of complex interventions. Results: The different sections of the structured approach resulted in outputs that built the necessary components (literature review, situation analysis) for informing the Theory of Change. A Theory of Change map is presented, which includes transparent documentation of the assumptions and logic behind the activities to drive the desired change. In addition, it documents the indicators necessary to measure fidelity and draw conclusions as to hypothesised effects of different mechanisms of action in subsequent evaluation. Conclusion: In addition to the details of ensuring robust evaluation design, there are a number of considerations that are particular to the context that must be taken into account in programme development, including the relationships between ultimate beneficiaries, implementers, host government and institutions, donors, and programme evaluators. Structured methods from existing frameworks can be drawn upon to use and collate relevant information to maximise the local applicability of a generic evidence base. Theory of Change, with its documented assumptions can form the basis of subsequent evaluation and iterative programme refinement, contributing to a more scientifically valid means of developing mental health programmes for scale up.

AB - Background: Protecting drinking water supplies from pathogens such as Cryptosporidium parvum is a major concern for water utilities worldwide. The sensitivity and specificity of current detection methods are largely determined by the effectiveness of the concentration and separation methods used. The purpose of this study is to develop micromixers able to specifically isolate and concentrate Cryptosporidium, while allowing in situ analysis. Results: In this study, disposable microfluidic micromixers were fabricated to effectively isolate Cryptosporidium parvum oocysts from water samples, while allowing direct observation and enabling quantification of oocysts captured in the device using high quality immunofluorescence microscopy. In parallel, quantitative analysis of the capture yield was carried out by analyzing the waste from the microfluidics outlet with an Imaging Flow Cytometer. At the optimal flow rate, capture efficiencies up to 96% were achieved in spiked samples. Conclusions: Scaled microfluidic isolation and detection of Cryptosporidium parvum will provide a faster and more efficient detection method for Cryptosporidium compared to other available laboratory-scale technologies. PMID- 29599822 TI - Novel phenotype of 5p13.3-q11.2 duplication resulting from supernumerary marker chromosome 5: implications for management and genetic counseling. AB - Background: Supernumerary marker chromosomes derived from chromosome 5 (SMC5) and 5p13 duplication syndrome are rare disorders, and phenotypic descriptions of patients are necessary to better define genotype-phenotype correlations for accurate, comprehensive genetic counseling. The purpose of this study is to highlight the unique findings of a patient with a 5p13.3-q11.2 duplication arising from a SMC5 and compare and contrast the phenotype with cases in the literature. Case presentation: We report on an adult male with a 22 Mb duplication of chromosome 5p13.3-q11.2 resulting from a small SMC5. The patient has a history of prenatal polyhydramnios, dysmorphic features, respiratory issues, talipes equinovarus, hypotonia, developmental delay, and autistic features. The patient also has novel features of aortic dilation, pectus excavatum, kyphoscoliosis, and skin striae, suggestive of a connective tissue disorder. Despite these features he did not meet clinical diagnostic criteria for a well-characterized connective tissue disorder. Additional molecular genetic testing for syndromic and non-syndromic aortic aneurysms was negative. Conclusions: Many of the patient's features are consistent with individuals reported with 5p13 duplication syndrome and similar cases of SMC5, including polyhydramnios, macrocephaly, dolichocephaly, pre-auricular pits, arachnodactyly, respiratory problems, and developmental delays. It is unclear if the patient's unique features of aortic dilation, pectus excavatum, kyphoscoliosis, and skin striae could be novel features of the SMC5 given its rarity and the few well phenotyped adults in the literature. This report reviews the literature and provides additional phenotypic information to define the genotype-phenotype correlation of SMC5 and 5p13 duplication syndrome.

PMID- 29599823 TI - Regional differences in the prevalence of diabetic retinopathy: a multi center study in Brazil. AB - Background: Diabetic retinopathy has a significant impact in every healthcare system. Despite that fact, there are few accurate estimates in the prevalence of DR in Brazil's different geographic regions, particularly proliferative DR and diabetic macular edema. This study aims to determine the prevalence of diabetic retinopathy in Brazil's five continental regions and its determinant factors. Methods: This multi center, cross-sectional, observational study, conducted between August 2011 and December 2014, included patients with type 1 diabetes from the 5 Brazilian geographic regions (South, Southeast, North, Northeast and Midwest). During a clinical visit, a structured questionnaire was applied, blood sampling was collected and each patient underwent mydriatic binocular indirect ophthalmoscopy evaluation. Results: Data was obtained from 1644 patients, aged 30.2 +/- 12 years (56.1% female, 54.4% Caucasian), with a diabetes duration of 15.5 +/- 9.3 years. The prevalence of diabetic retinopathy was 242 (36.1%) in the Southeast, 102 (42.9%) in the South, 183 (29.9%) in the North and Northeast and 54 (41.7%) in the Midwest. Multinomial regression showed no difference in the prevalence of non-proliferative diabetic retinopathy in each geographic region, although, prevalence of proliferative diabetic retinopathy (p = 0.022), and diabetic macular edema (p = 0.003) was higher in the Midwest. Stepwise analyses reviled duration of diabetes, level of HbA1c and hypertension as independent variables. Conclusions: The prevalence of non proliferative diabetic retinopathy in patients with type 1 diabetes was no different between each geographic region of Brazil. The Midwest presented higher prevalence of proliferative diabetic retinopathy and diabetic macular edema. Duration of DM and glycemic control is of central importance to all. Hypertension is another fundamental factor to every region, at special in the South and Southeast. Glycemic control and patients in social and economic vulnerability deserves special attention in the North and Northeast of Brazil. PMID- 29599825 TI - Case-control study on individual risk factors of carpal tunnel syndrome. AB - This study was conducted to observe the characteristics of the risk factors of carpal tunnel syndrome (CTS) in Chinese population. CTS of 1,512 outpatients aged 41-70 years were without any other diseases which could cause numbness as a case group, and 4,536 non-CTS outpatients as a control group were involved in the study in 2013-2014. Both groups received a questionnaire and the case group received another electrical physiological examination. The results showed the odds ratio (OR) of age is 0.990 (95% CI, 0.984-0.996). The OR of BMI is 1.096 (95% CI, 1.077-1.115). The OR of smoking is 4.862 (95% CI, 3.991-5.925). The OR of wrist injury is 1.313 (95% CI, 1.019-1.691). The OR of diabetes mellitus is 1.837 (95% CI, 1.557-2.168). The OR of hypertension is 0.805 (95% CI, 0.688 0.942). The OR of hypothyroidism is 1.385 (95% CI, 1.119-1.715). The OR of rheumatic disease is 4.450 (95% CI, 3.712-5.215). The results showed that sex, age, smoking, wrist injury, diabetes mellitus, hypothyroidism and wrist working are all risk factors of CTS. Hypertension could be a protection factor of CTS in early phase but will increase the risk in a long-term high blood pressure. Smoking, alcohol and diabetes mellitus can be predictors of moderate and severe CTS. PMID- 29599826 TI - Gas chromatography-time of flight/mass spectrometry-based metabonomics of changes in the urinary metabolic profile in osteoarthritic rats. AB - The aim of the present study was to explore changes in the urinary metabolic spectrum in rats with knee osteoarthritis, using gas chromatography-time of flight/mass spectrometry (GC-TOF/MS) to determine the metabonomic disease pathogenesis. Sprague-Dawley rats were randomly divided into the control and model groups (n=8/group), and 20 ul of 4% papain and 0.03 M L-cysteine was injected into the right knee on days 1, 3 and 7 to establish the knee osteoarthritis model. Following 14 days, urine was collected over 12 h and cartilage ultrastructural damage was assessed by hematoxylin-eosin staining. GC TOF/MS, combined with principal component analysis, partial least squares discriminant modeling and orthogonal partial least squares discriminant modeling, was used to analyze the changes in the metabolic spectrum trajectory and to identify potential biomarkers and their related metabolic pathways. Compared with the control group, the synovial cell lining of the knee joint exhibited proliferation, inflammatory cell infiltration and collagen fiber hyperplasia in the knee osteoarthritis group. A total of 23 potential biomarkers were identified, including alanine, alpha-ketoglutarate, asparagine, maltose and glutamine. Furthermore, metabolomic pathogenesis of osteoarthritis may be related to disorders of amino acid metabolism, energy metabolism, fatty acid metabolism, vitamin B6 metabolism and nucleic acid metabolism. PMID- 29599827 TI - Effects of sevoflurane pretreatment on the apoptosis of rat H9c2 cardiomyocytes and the expression of GRP78. AB - The protective effect of sevoflurane on apoptosis of rat H9c2 cardiomyocytes induced by H2O2 and the effect on the expression of glucose-regulated protein 78 (GRP78) were investigated. H9c2 cells were routinely cultured and divided into the control, model and sevoflurane groups. Cells in the model group were treated with 400 uM H2O2, and cells in the sevoflurane group were pretreated with sevoflurane prior to treatment with 400 uM H2O2. MTT assay was used to assess cell viability. Annexin V-propidium iodide (AV-PI) double staining flow cytometry was used to detect apoptosis. The intracellular free Ca2+ concentration was measured by the fluorescence-based assay using Fluo-3 AM as a calcium ion fluorescence probe. The mRNA expression level of GRP78 and protein expression levels of GRP78, CHOP and caspase-12 were measured using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis, respectively. The assays showed that after sevoflurane pretreatment the H9c2 cell viability was significantly increased, whereas the H2O2-induced apoptosis, intracellular Ca2+ concentration, mRNA expression of GRP78, and the protein expression of GRP78, CHOP and caspase-12 were all reduced. The results show that pretreatment with sevoflurane inhibited H2O2-induced apoptosis in H9c2 cells. The mechanism may be related to inhibition of the stress-related protein GRP78 expression in endoplasmic reticulum, resulting in decreased intracellular Ca2+ concentration and the downregulation of CHOP and caspase-12 expression levels. PMID- 29599828 TI - Age-related changes of the spinal cord: A biomechanical study. AB - Although it is known that aging plays an important role in the incidence and progression of cervical spondylotic myelopathy (CSM), the underlying mechanism is unclear. Studies that used fresh bovine cervical spinal cord report the gray matter of the cervical spinal cord as being more rigid and fragile than the white matter. However, there are no reports regarding the association between aging an tensile and Finite Element Method (FEM). Therefore, FEM was used based on the data pertaining to the mechanical features of older bovine cervical spinal cord to explain the pathogenesis of CSM in elderly patients. Tensile tests were conducted for white and gray matter separately in young and old bovine cervical spinal cords, and compared with their respective mechanical features. Based on the data obtained, FEM analysis was further performed, which included static and dynamic factors to describe the internal stress distribution changes of the spinal cord. These results demonstrated that the mechanical strength of young bovine spinal cords is different from that of old bovine spinal cords. The gray matter of the older spinal cord was significantly softer and more resistant to rupture compared with that of younger spinal cords (P<0.05). Among the old, although the gray matter was more fragile than the white matter, it was similar to the white matter in terms of its rigidity (P<0.05). The in vitro data were subjected to three compression patterns. The FEM analysis demonstrated that the stress level rises higher in the old spinal cords in response to similar compression, when compared with young spinal cords. These results demonstrate that in analyzing the response of the spinal cord to compression, the age of patients is an important factor to be considered, in addition to the degree of compression, compression speed and parts of the spinal cord compression factor. PMID- 29599830 TI - beta-inducible gene-h3 promotes human breast carcinoma cell metastasis by activating the phosphatidylinositol 3-kinase/protein kinase B signaling pathway. AB - Metastatic breast cancer is one of the most common metastatic tumors. Although studies have validated the role of beta-inducible gene-h3 (betaig-h3) in human biology and disease, the detailed mechanisms mediated by betaig-h3 in breast carcinoma metastasis remain unclear. Thus, the present study investigated the role and potential mechanism of betaig-h3 during breast carcinoma cell metastasis. The results indicated that the upregulation of betaig-h3 significantly promotes the growth and inhibits the cisplatin-induced apoptosis of breast carcinoma cells. It was also demonstrated that betaig-h3 promoted the migration and invasion of human breast carcinoma cells in vitro and in vivo. Furthermore, the results demonstrated that betaig-h3 upregulated the overall expression and phosphorylation of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt) in human breast carcinoma cells. By contrast, betaig-h3 knockdown reversed the betaig-h3-mediated characteristics of breast carcinoma cells. Thus, the current study demonstrated that the PI3K/Akt signaling pathway serves a role in betaig-h3-induced human breast cancer cell metastasis and that betaig-h3 transfection enhances the metastatic potential of human breast carcinoma cells via the PI3K/Akt signaling pathway. These observations contribute to the understanding of the potential mechanism of human breast carcinoma cell growth and metastasis and suggest that betaig-h3 may be a promising therapeutic target for the treatment of human breast carcinoma. PMID- 29599829 TI - microRNA-10b expression and its correlation with molecular subtypes of early invasive ductal carcinoma. AB - The present study aimed to determine whether the expression of microRNA (miR)-10b was correlated with the molecular subtypes of early invasive ductal carcinoma of the breast. In situ hybridization was used to detect the expression of miR-10b in 193 patients diagnosed with early invasive ductal carcinoma. Immunohistochemistry was performed to evaluate the expression of estrogen receptor (ER)-alpha, progesterone receptor (PR) and human epidermal growth factor receptor-2 (Her-2). The positive expression rate of miR-10b in patients with early invasive ductal carcinoma with ER-alpha (+) or PR (+) was decreased compared with ER-alpha (-) or PR (-) patients (P<0.05). Furthermore, the positive expression rate of miR-10b in patients with Her-2 (-) was significantly increased compared with patients that were Her-2 (+) (P=0.031). The positive expression rate of miR-10b in the luminal B subtype was significantly decreased compared with that in the luminal A, Her-2 and basal-like subtypes (P=0.037). In patients that were identified as miR-10b (+), the median disease-free survival time was significantly increased in patients that were ER-alpha (+)/PR (+)/Her-2 (-) compared with patients that were ER-alpha (-)/PR (-)/Her-2 (+) (P<0.05). In addition, the median disease-free survival time was significantly decreased in Her-2 overexpression and basal-like subtypes when compared with luminal A and B subtypes (P<0.05). The molecular subtype was an independent prognostic factor for early invasive ductal carcinoma (odds ratios for luminal B, Basal-like, and Her-2 overexpression were 2.900, 5.232 and 4.214, respectively; all P<0.05). Positive expression of miR-10b may also be a prognostic risk factor (odds ratio >1), though this was not statistically significant (P>0.05). The present findings indicated that miR-10b positive expression was correlated with the expression of ER-alpha, Her-2 and the molecular subtypes of early invasive ductal carcinoma of the breast. PMID- 29599831 TI - Effect of curcumin on vascular endothelial growth factor in hypoxic HepG2 cells via the insulin-like growth factor 1 receptor signaling pathway. AB - To investigate the anti-angiogenic effect and underlying molecular mechanisms of curcumin on HepG2 cells under hypoxic conditions, insulin-like growth factor 1 receptor (IGF-1R) knockout HepG2 cells were constructed using a clustered regularly interspaced short palindromic repeats/Cas9 genome-editing system. Hypoxic conditions were generated using cobalt chloride (CoCl2). An MTT assay was performed to measure the effects of curcumin on cell viability in hypoxia-induced IGF-1R knockout HepG2 cells, while western blot analysis was used to detect the expression of IGF-1R, phosphorylated (p)-protein kinase B (Akt), p-extracellular signal-regulated kinases (Erk)1/2, hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF). The results revealed that CoCl2 at low concentrations (50 and 100 uM) had no significant inhibitory effects on IGF 1R knockout HepG2 cells. However, with increasing concentrations of CoCl2 and treatment time, cell viability decreased and was significantly reduced at 150, 200 and 400 uM compared with the control group (P<0.05). The expression of HIF 1alpha and VEGF were significantly increased when the cells were treated with 150 or 200 uM CoCl2 compared with the control (P<0.05). With the increase of CoCl2 concentration or the treatment time, the expression of HIF-1alpha and VEGF were upregulated gradually. Additionally, curcumin significantly inhibited the expression of p-Akt, p-Erk1/2, HIF-1alpha and VEGF in hypoxia-induced IGF-1R knockout HepG2 cells. In conclusion, the findings of the present study suggest that curcumin may serve a pivotal role in tumor suppression via the inhibition of IGF-1R-mediated angiogenesis under hypoxic conditions.

AB - The transplantation of neural stem cells (NSCs) has been demonstrated as a potential treatment strategy for traumatic brain injury (TBI). Cu, Zn-superoxide dismutase (SOD1) is an important antioxidant enzyme that detoxifies intracellular reactive oxygen species, thereby protecting cells from oxidative damage. PEP-1, a peptide carrier, is able to deliver full-length native peptides or proteins into cells. Therefore, the current study investigated the effect of the transplantation of NSCs in combination with PEP-1-SOD1 for the treatment of experimental TBI in rats. Initially, the effect of PEP-1-SOD1 on the proliferation of NSCs was evaluated by MTT assay. PEP-1-SOD1 (0.5, 2.5 and 4.5 uM) significantly increased the proliferation rates of NSCs at 24, 48 and 72 h in a dose-dependent manner. PEP-1-SOD1 also promoted the differentiation of NSCs in vitro. The in vivo experiment showed that PEP-1-SOD1 in combination with NSC transplantation significantly improved the functional recovery of rats following TBI compared with NSC transplantation alone. A significant increase in brain aquaporin-4 (AQP4) mRNA and protein expression levels was observed 4 days post TBI in PEP-1-SOD1, NSCs and PEP-1-SOD1 + NSCs groups compared with the saline group. The PEP-1-SOD1 + NSCs group showed a further increase of AQP4 mRNA and protein expression levels compared with the NSCs and PEP-1-SOD1 groups. In conclusion, the current data suggests that PEP-1-SOD1 may promote the proliferation and differentiation of NSCs, and thereby improve the functional recovery of TBI model rats following NSCs transplantation through upregulating the expression of AQP4.

AB - Post-menopausal osteoporosis is one of the most common bone diseases in women. The aim of the present study was to predict the diagnostic function modules from a differential co-expression gene network in order to enhance the current understanding of the biological processes and to promote the early prevention and intervention of post-menopausal osteoporosis. The diagnostic function modules were extracted from a differential co-expression network by the established protein-protein interaction (PPI) network analysis. First, significant genes were identified from the differential co-expression network, which were regarded as seed genes. Starting from the seed genes, the sub-networks in this disease, referred to as diagnostic function modules, were exhaustively searched and prioritized through a snowball sampling strategy to identify genes to accurately predict clinical outcomes. In addition, crucial function inference was performed for each diagnostic function module. Based on the microarray and PPI data, the differential co-expression network was constructed, which contained 1,607 genes and 4,197 interactions. A total of 110 seed genes were identified, and nine diagnostic modules that accurately distinguished post-menopausal osteoporosis from healthy controls were screened out from these seed genes. The diagnostic modules may be associated with five functional pathways with emphasis on metabolism. A total of nine diagnostic functional modules screened in the present study may be considered as potential targets for predicting the clinical outcomes of post-menopausal osteoporosis, and may contribute to the early diagnosis and therapy of osteoporosis. PMID- 29599834 TI - Improvement of postoperative cognitive dysfunction and attention network function of patients with ischemic cerebrovascular disease via dexmedetomidine. AB - The protective effect of dexmedetomidine on cognitive dysfunction and decreased attention network function of patients with ischemic cerebrovascular disease after stenting was investigated. Fifty-eight patients with ischemic cerebrovascular disease undergoing stenting in Guizhou Provincial People's Hospital were selected and randomly divided into control group (n=29) and dexmedetomidine group (n=29). The dexmedetomidine group was treated with dexmedetomidine before induced anesthesia, while the control group was given the same dose of normal saline; and the normal volunteers of the same age were selected as the normal group (n=29). At 3 days after operation, the levels of serum S100B and nerve growth factor (NGF) in each group were detected using the enzyme-linked immunosorbent assay, and the level of brain-derived neurotrophic factor (BDNF) was detected via western blotting. Montreal cognitive assessment (MoCA) and attention network test (ANT) were performed. Moreover, the cognitive function and attention network function, and the effects of dexmedetomidine on cognitive function and attention network function were evaluated. The concentrations of serum S100B and NGF in dexmedetomidine group was lower than those in control group (P<0.01). The results of western blotting showed that the levels of serum BDNF in control group and dexmedetomidine group were significantly lower than that in normal group (P<0.01), and it was higher in dexmedetomidine group than that in control group (P<0.01). Besides, both MoCA and ANT results revealed that the visual space and executive function scores, attention scores, delayed memory scores, targeted network efficiency and executive control network efficiency in dexmedetomidine group were obviously higher than those in control group (P<0.01). The cognitive function and attention network function of patients with ischemic cerebrovascular disease have a certain degree of damage, and the preoperative administration of dexmedetomidine can effectively improve the patient's cognitive dysfunction and attention network function after operation. PMID- 29599835 TI - Antibacterial effects of bacteriocins isolated from Lactobacillus rhamnosus (ATCC 53103) in a rabbit model of knee implant infection. AB - Infection following orthopedic surgery is a major complication that can have serious implications on patient health. The present study aimed to investigate the antibacterial effects of bacteriocins obtained from Lactobacillus rhamnosus on a rabbit model of Staphylococcus aureus infection following knee replacement surgery. Blood samples were collected 1, 2, 3, 4 and 5 days after bacteriocin injection, and C-reactive protein (CRP) and interleukin (IL)-6 levels were measured using commercial ELISA kits. In addition, biofilm formation was evaluated by fluorescence microscopy. Bacteriocins were identified to exhibit significant inhibitory effects on Staphylococcus aureus biofilm formation, and on CRP and IL-6 levels in the serum, following surgery and infection (all P<0.05 vs. the control group). The results of the present study indicate that bacteriocins are a potential agent for the prevention of orthopedic postoperative infections. PMID- 29599836 TI - Acute kidney injury following the first stage of the ALPPS procedure: A case report. AB - Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a novel approach for performing liver resection, and the number of clinical applications of this technique has rapidly increased within recent years. ALPPS is important in patients who have insufficient residual liver volume and cannot undergo radical hepatic resection. The most common postoperative complications of ALPPS include biliary fistula and infection. To date, postoperative acute kidney injury following ALPPS has not been reported. The current study reports the case of a 63-year-old patient with hepatitis B-induced cirrhosis who underwent the first stage of ALPPS without completion of the second step. The patient developed postoperative acute kidney injury following ALPPS. The present case study suggests that the use of ALPPS in patients at risk of chronic renal damage should be approached with caution in order to avoid postoperative acute kidney injury. Furthermore, improvements in surgical techniques and skills of the surgeons performing the procedure are required to reduce the surgery duration and improve patient outcomes. PMID- 29599837 TI - Inhibition of prostate cancer DU145 cell growth with small interfering RNA targeting the SATB1 gene. AB - Prostate cancer is a common visceral cancer of men worldwide. It is important to develop a more effective treatment for prostate cancer to overcome the treatment resistance that occurs with recurrence. RNA interference has been demonstrated to be a powerful tool for gene knockdown and has potential as a cancer treatment. It has been previously demonstrated that staining of special AT-rich sequence binding protein 1 (SATB1) was stronger in prostatic carcinoma with metastasis compared with prostatic carcinoma without metastasis. In the present study, SATB1 small interfering (si)RNA was transfected into prostate cancer DU145 cells and normal human lung fibroblast cells, and cell proliferation was investigated using a Cell Counting kit-8. Three siRNA were transfected into cells using siPORT Lipid Transfection agent, and blank control and negative control groups were established. The cells were harvested and SATB1 mRNA and protein expression was determined by reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. DU145 cell adhesion, migration and invasion capabilities were determined using cell adhesion, Transwell and Transwell with Matrigel assays, respectively. Silencing SATB1 significantly inhibited DU145 cell growth, adhesion, migration and invasive capability in vitro, indicating that a SATB1-targeting siRNA was successfully engineered. The results of the present study suggest that SATB1 siRNA may be a potential agent for treating human prostate cancer. PMID- 29599838 TI - Assessment of recombinant plasmid expressing fusion antigen Ag85B-Rv3425 in management of acute tuberculosis infection in mice. AB - The emergence of drug-resistant tuberculosis (TB) and HIV-TB co-infection fuels an urgent need to develop novel therapeutic approaches, including therapeutic vaccines. Therapeutic vaccines have been proven to be a good strategy by inducing antigen specific immune responses against TB infection. In the present study, a recombinant plasmid based on lentiviral vector expressing fusion antigen Ag85B Rv3425 (A3), and was constructed the immunogenicity and treatment effects in TB mice were assessed. The results showed that A3 delivered by the plasmid could be expressed appropriately in vivo and induced higher production of tumor necrosis factor-alpha and interleukin-2 compared with A3 recombinant protein in mice. Moreover, the recombinant plasmid expressing A3 confered resistance to acute TB infection in mice, characterized by a reduction in the bacterial load in the lungs and spleen, as well as attenuated TB lesions in lung tissues. These results implicated that the recombinant plasmid based on lentiviral vector expressing A3 is a potent and promising therapeutic agent to treat acute TB infection. PMID- 29599839 TI - Rapamycin protects against paraquat-induced pulmonary epithelial-mesenchymal transition via the Wnt/beta-catenin signaling pathway. AB - Paraquat (PQ) is a herbicide that is widely used in developing countries, and pulmonary fibrosisis one of the most typical features of PQ poisoning. The molecular mechanism underlying PQ toxicity is largely unknown, which makes it difficult to treat. In the present study, western blot analysis, reverse transcription-quantitative polymerase chain reaction and fluorescent immunostaining were used to analyze the effects of rapamycin on PQ-induced epithelial-mesenchymal transition (EMT) in A549 and MRC-5 cells. It was revealed that rapamycin significantly downregulated the mesenchymal cell marker, alpha smooth muscle actin, and significantly upregulated the epithelial cell marker, E cadherin, at mRNA and protein expression levels compared with the PQ group. Treatment with PQ significantly increased Wnt1, low-density lipoprotein receptor related protein (LRP)5, LRP6 and beta-catenin expression levels in A549 cells, while rapamycin significantly inhibited these effects of PQ. Activation of the Wnt signaling pathway using lithium chloride attenuated the inhibitory effects of rapamycin on PQ-induced EMT. In conclusion, rapamycin protects against PQ-induced pulmonary EMT via the Wnt/beta-catenin signaling pathway. PMID- 29599840 TI - Effect of dihydroarteminin combined with siRNA targeting Notch1 on Notch1/c-Myc signaling in T-cell lymphoma cells. AB - The effectiveness of therapy combining dihydroartemisinin (DHA) and small interfering RNA targeting Notch1 (siNotch1) in T-cell lymphoma remains unknown. The present study explored the potential and possible mechanisms of combined dihydroarteminin, and siNotch1 therapy for T-cell lymphoma. It was demonstrated that the viability rates of siRNA-DHA-treated cells was significantly suppressed in comparison with those in control cells, control siRNA cells, siRNA-treated cells and DHA-treated cells (P<0.01). Additionally, there was a significant increase in cell apoptosis of siRNA-DHA-treated cells in comparison with those of control cells, control siRNA cells, siRNA-treated cells, DHA-treated cells (P<0.05). Furthermore, Notch1 and c-Myc mRNA and protein expression were decreased in siRNA-DHA-treated cells (P<0.05). The present study demonstrated that DHA combined with siNotch1 is able to suppress proliferation and promote apoptosis, and downregulate the expression of Notch1 and c-Myc mRNA and protein in T-cell lymphoma cells. Targeting Notch1/c-Myc signaling with siRNA and DHA may represent a novel strategy for treating human T-cell lymphoma. PMID- 29599841 TI - The anti-fatigue activities of Tuber melanosporum in a mouse model. AB - Tuber melanosporum (TM) is an edible fungus that exhibits antioxidant and anti tumor activity via its unique bioactive metabolites. The present study analyzed the anti-fatigue effects of TM using a BALB/c mouse model. The anti-fatigue properties of TM were evaluated by assessing the endurance of mice by performing forced swimming, rotary rod and running tests. Following 2 weeks TM treatment, hepatic and muscular ATP, and glycogen levels were increased in mice subjected to 30 min swimming, compared with controls. Similarly, levels of serum lactic acid and lactic dehydrogenase were decreased in the same group, compared with the control. Additionally, TM treatment reduced reactive oxygen species and malondialdehyde levels, and increased superoxide dismutase and glutathione peroxidase levels in the muscle, liver and/or serum. The effect of TM on hormone levels was also investigated in the present study, as different efficacies of TM were observed in male and female mice. TM treatment increased serum levels of progesterone, estradiol and testosterone in female and male mice, whereas a decrease in serum luteinizing hormone levels was only observed in females. A decrease in serum follicle-stimulating hormone levels was identified in females, whereas an increase was observed in males. The current study demonstrated that the anti-fatigue effects of TM occur via the regulation of oxidative stress, energy metabolism and hormone levels. PMID- 29599842 TI - Therapeutic effects of simvastatin combined with kallistatin treatment for pediatric burn patients with sepsis. AB - The aim of the present study was to examine the combined efficacy of simvastatin and kallistatin treatment for pediatric burn sepsis. A total of 72 pediatric patients with burn sepsis were recruited and randomly divided into 3 groups, receiving simvastatin (40 mg/day), kallistatin (20 mg/day) or combined treatment. ELISA, reverse transcription-quantitative polymerase chain reaction, western blotting and flow cytometry were used to analyze the therapeutic effects of simvastatin and kallistatin. The results revealed that combined treatment in pediatric burn sepsis patients decreased the inflammatory cytokine tumor necrosis factor alpha and interleukin (IL)-1beta serum levels, whereas it increased IL-10 and human leukocyte antigen-D related levels. In addition, administration of combined simvastatin and kallistatin decreased the blood urea nitrogen and serum creatinine levels in the patients. It was also demonstrated that Toll-like receptor 4 expression on the surface of monocytes was markedly decreased, while suppressor of cytokine signaling-3 expression was increased in the combined treatment group as compared with the kallistatin or simvastatin treatment alone. Combined treatment also promoted human endothelial cell (HEC) growth compared with the single treatment groups and inhibited the high mobility group box-1 (HMGB1) levels, HMGB1-induced nuclear factor-kappaB activation and inflammatory gene expression levels in these cells. The study further demonstrated that combined treatment significantly decreased HEC apoptosis through the upregulation of B-cell lymphoma 2 (Bcl-2) and P53 expression levels, as well as downregulation of Bcl-2-associated X protein and caspase-3 levels. In conclusion, these observations indicated that combined treatment with simvastatin and kallistatin inhibited HEC apoptosis, which may be a potential therapeutic strategy for the treatment of pediatric burn sepsis patients. PMID- 29599843 TI - Platelet-rich plasma shows beneficial effects for patients with knee osteoarthritis by suppressing inflammatory factors. AB - Knee osteoarthritis is a degenerative disease that may develop due ageing, obesity, strain, congenital abnormal joints, joint deformity or trauma. It is caused by many factors, such as degradation of articular cartilage injury, joint edge and subchondral bone hyperplasia of reactivity. Platelet-rich plasma (PRP) is an autologous blood sample that contains highly concentrated platelets and multiple cell growth factors. PRP promotes synovial cell proliferation and differentiation and may recover cartilage morphology. In the present study, the clinical efficacy of PRP was investigated in patients with knee osteoarthritis aged between 18 and 30 years in a phase-III clinical study. Following an 8-week baseline, patients with knee osteoarthritis were randomized into once-weekly, double-blind treatment with PRP (2-14 ml) or placebo groups. The results indicated that patients with osteoarthritis treated with PRP had modulated plasma concentrations of inflammatory factors and pro-angiogenic factors compared with the placebo group. Treatment responses were assessed by median percent reduction in inflammatory and pro-angiogenic factors and these improved with PRP treatment compared with the placebo. Clinical data indicated that PRP alleviated knee osteoarthritis and reduced humoral and cellular immune responses that led to beneficial effects on histological parameters. Inflammation was significantly alleviated in patients receiving PRP compared with the placebo group. The most common treatment-emergent adverse events in the presence of PRP were hypertension and proteinuria. In conclusion, treatment with PRP for patients with knee osteoarthritis presented beneficial effects in alleviating joint inflammation, cartilage destruction and bone damage, and repairing joint tissue. These results suggested that PRP may be a potential therapeutic agent for knee osteoarthritis. PMID- 29599844 TI - Effect of the polyphenol composition BP-C3 on haematological and intestinal indicators of 5-fluorouracil toxicity in mice. AB - BP-C3 is a formulation, which comprises lignin-derived polyphenolic composition of benzenepolycarboxylic acids (BP-Cx-1) with iron complex, selenium, ascorbic acid and retinol, and possesses geroprotective activity. The present study examined the effect of BP-C3 (80 mg/kg, administered 18 times in total by gavage) on the development of haematological and intestinal manifestations of toxicity following 5-fluorouracil (5-FU; 150 mg/kg, administered once via intravenous injection) administration in outbred male Swiss-H Rappolovo (SHR) mice. The use of BP-C3 on therapeutic and preventative/therapeutic schedules demonstrated that it was protective against the toxic effect of 5-FU exerted on the lymphopoietic organs. Administering VR-S3 24 h after 5-FU (therapeutic schedule) had an effect on the recovery of leukopoiesis and prevented anaemia in the mice. In the mice that received 5-FU and 5-FU with BP-C3 prior to and following administration of the chemotherapeutic agent (preventative/therapeutic schedule), mild anaemia developed by day 7. Administration of BP-C3 without 5-FU did not affect blood cell differentiation in the mice. Thus, BP-C3, depending on the administration schedule, had different effects on the haematological parameters of haematopoietic organs and peripheral blood in mice exposed to 5-FU. BP-C3 promoted intestinal crypt survival when administered on the preventative/therapeutic and therapeutic schedules, suggesting that the formulation protects the epithelium of the small intestine against damage by 5 FU. PMID- 29599845 TI - Blood supply characteristics of pedunculated hepatocellular carcinoma prior to and following transcatheter arterial chemoembolization treatment: An angiographic demonstration. AB - Pedunculated hepatocellular carcinoma (P-HCC) is a rare type of HCC, defined as a carcinoma protruding from the liver with or without a pedicle with a low degree of liver invasion. The present study aimed to evaluate the characteristics of blood supply of P-HCC prior to and following transcatheter arterial chemoembolization (TACE) treatment. Angiographic findings prior to and following TACE treatment in 39 patients with P-HCC were analyzed retrospectively. Angiography performed at the first TACE session revealed 70 tumor-feeding arteries collectively in all patients, including 31/70 (44.0%) extrahepatic parasitic arteries in 23/39 patients (59.0%). The intrahepatic arteries served as the main blood supply to P-HCC in all patients. Extrahepatic collateral blood supplies to P-HCCs were significantly associated with larger tumor diameter (chi2=164.000, P<0.001), but not tumor location (chi2=7.358, P=0.061). Following repeated TACE treatment, all angiographies revealed a total of 131 tumor feeding arteries collectively in all patients, including intrahepatic arteries (54/131) and extrahepatic collateral arteries (78/131) in 31 patients (79.5%). Compared with angiographies performed at the initial TACE treatment, these results also demonstrated an increase in the number of extrahepatic collateral arteries, which produced 47 new blood vessels (chi2=4.278, P=0.039). P-HCC tumor lesions readily acquired a parasitic blood supply from adjacent vessels following repeated TACE. Intrahepatic arteries functioned as the main blood supply for P-HCC, whereas extrahepatic collateral arteries were complementary to P-HCC, regardless of whether the patient was pre- or post-TACE. Extrahepatic collateral supplies to P HCCs that originated from adjacent vessels were rich, were closely associated with tumor size, and were prone to be newly established following repeated TACE. PMID- 29599846 TI - Reference values for fatigued versus non-fatigued limb symmetry index measured by a newly designed single-leg hop test battery in healthy subjects: a pilot study. AB - Purpose: There is sparse evidence for return to sport criteria after knee injury. Functional performance deficits, particularly in fatigued muscular condition, should be verified prior to the attempt to return to high-risk pivoting sports. The purpose of this study was to generate reference values for the limb symmetry index (LSI) of healthy subjects in fatigued and non-fatigued muscular condition in a newly designed test battery. Methods: Forty-two healthy subjects [22 females, 20 males; mean (SD) age 30.4 (6.6) years] were evaluated using a test battery consisting of an isometric strength test, a series of five single-leg hop tests and an integrated fatigue protocol. Subjective physical activity was assessed with the Tegner Activity Scale (TAS). The cut-off values for healthy subjects were calculated considering the fifth percentile as the minimum reference value for the LSI and single-leg hop distance. Results: The mean (SD) overall LSI was 98.8% (4.6). No significant gender or age specific differences in limb symmetry were observed. The comparison of the non-fatigued LSI with the overall LSI revealed no clinically relevant change due to muscular fatigue. Repeated measures ANOVA revealed a significant within effect on fatigue/non fatigue condition (F(1,38) = 18.000; p < 0.001, eta2 = 0.321) on absolute single leg hop distance. Moreover, a significant between effect on the TAS-parameter (F(1,38) = 5.928; p = 0.020, eta2 = 0.135 between: TAS <= 5/TAS > 5) and on gender (F(1,38) = 23.956; p < 0.001, eta2 = 0.387) could be detected. Conclusions: The absolute jumping distance in the single-leg hop for distance was significantly reduced due to fatigue. No clinically relevant effect of muscular fatigue was observed on limb symmetry in our study sample. Gender and physical activity are important factors to be considered when interpreting reference values. PMID- 29599848 TI - The Co-creation and Feasibility of a Compassion Training as a Follow-up to Mindfulness-Based Cognitive Therapy in Patients with Recurrent Depression. AB - The aim of this study was to assess the feasibility, acceptability and preliminary effectiveness of Mindfulness - Based Compassionate Living (MBCL) as a follow-up intervention to Mindfulness Based Cognitive Therapy in adults with recurrent depression. We conducted an uncontrolled study in 17 patients with recurrent depression, in two successive groups. The first group contained novices to compassion training (N = 14); in the second group, ten of these participated again, in addition to three new participants (N = 13). The overall group contained 15 females and 2 males, aged between 37 and 71. The MBCL program was qualitatively evaluated using post-intervention focus group interviews in both groups. In addition, self-report questionnaires assessing depressive symptoms, worry and both self-compassion and mindfulness skills were administered before and after MBCL. No patients dropped out of the intervention. Average attendance was 7.52 (SD 0.73) out of eight sessions. Helpful elements were theory on the emotion regulation systems, practicing self-compassion explicitly and embodiment of a compassionate attitude by the teachers. Unhelpful elements were the lack of a clear structure, lack of time to practice compassion for self and the occurrence of the so-called back draft effect. We adapted the program in accordance with the feedback of the participants. Preliminary results showed a reduction in depressive symptoms in the second group, but not in the first group, and an increase in self-compassion in both groups. Worry and overall mindfulness did not change. MBCL appears to be feasible and acceptable for patients suffering from recurrent depressive symptoms who previously participated in MBCT. Selection bias may have been a factor as only experienced and motivated participants were used; this, however, suited our intention to co-create MBCL in close collaboration with knowledgeable users. Examination of the effectiveness of MBCL in a sufficiently powered randomised controlled trial is needed. PMID- 29599847 TI - A multiplatform approach identifies miR-152-3p as a common epigenetically regulated onco-suppressor in prostate cancer targeting TMEM97. AB - Background: Prostate cancer (PCa) is a major cause of morbidity and mortality in men worldwide. MicroRNAs are globally downregulated in PCa, especially in poorly differentiated tumors. Nonetheless, the underlying mechanisms are still elusive. Herein, using combined analysis of microRNAs expression and genomewide DNA methylation, we aimed to identify epigenetically downregulated microRNAs in PCa. Results: We found that miR-152-3p was underexpressed in PCa and that lower expression levels were associated with promoter hypermethylation in accordance with TCGA dataset analysis. Functional in vitro assays suggest that miR-152-3p suppresses cell viability and invasion potential, whereas it promotes cell cycle arrest at S and G2/M phases. Additionally, miR-152-3p expression was associated with longer disease-free survival in PCa patients from TCGA. Finally, TMEM97, which is overexpressed in PCa, was identified as a novel miR-152-3p target gene. Conclusions: Our findings demonstrate the advantages of using a combinatory approach to identify microRNAs downregulated due to aberrant promoter methylation. MiR-152-3p downregulation and promoter methylation was found to be prevalent in primary PCa, which impairs its role in control of cell viability, cell cycle regulation and invasion. PMID- 29599849 TI - The Integration of the Workable Range Model into a Mindfulness-Based Stress Reduction Course: a Practice-Based Case Study. AB - Didactic teaching about stress is part of the Mindfulness-Based Stress Reduction (MBSR) curriculum. The content and methods of integrating conceptual teaching within the experiential pedagogy are rarely explored. Workable range is a model of stress and emotion regulation that illustrates patterns of physical, emotional and cognitive reactivity in relation to mindful presence. This is a qualitative case study of the inclusion of the workable range model into an MBSR course as a refinement of the didactic teaching about stress. The focus is to illuminate how the inclusion worked in practice. Ten staff, on a MBSR course in a higher educational setting, were recruited as participant researchers with an overlap between their own first-person investigation during the course and the research data. Adapted diagrams and written answers to two question schedules, completed as reflective exercises within the course, were analysed thematically using template analysis. This revealed how participant researchers engaged with and intuitively used the model to notice and describe their own patterns of feeling balanced or stressed and explore how they related to those experiences. How learning the model integrated with MBSR and the applicability of workable ranges as a teaching resource in MBSR is discussed. The study highlights questions about how conceptual and experiential teaching and learning interrelate in mindfulness based interventions. There is scope for further research using mindfulness practice as a first-person methodology to investigate the processes within mindfulness-based programs. PMID- 29599850 TI - How Is Stress Reduced by a Workplace Mindfulness Intervention? A Qualitative Study Conceptualising Experiences of Change. AB - Mindfulness-based interventions are effective as curative and preventative approaches to psychological health. However, the mechanisms by which outcomes are secured from such interventions when delivered in the workplace, and to a stressed workforce, are not well understood. The aim of the present study was to elicit and analyse accounts from past participants of a workplace mindfulness intervention in order to generate a preliminary model of how positive benefits appear to be secured. In-depth, semi-structured interviews were completed with 21 employees of a higher education institution who had completed an eight-week intervention based on Mindfulness-Based Stress Reduction, adapted for the workplace. Interviews invited participants to recount their experiences of the intervention and its impact, if any, on their work life. Aspects of the interview data that pertained to intervention experience and positive benefits were analysed using a version of grounded theory, leading to the generation of a provisional model of how positive change occurred. The model suggests that discrete, temporal experiences build on each other to generate multiple, positive benefits. As anticipated in mindfulness-based interventions, enhanced attentional capacity was important, but our provisional model also suggests that resonance, self-care, detection of stress markers, perceiving choice, recovering self-agency and upward spiralling may be central mechanisms that lead to positive outcomes. Understanding mechanisms of change may help support participant engagement and trust in work-based mindfulness programmes, and enhance participants' ability to apply mindfulness in their work life. PMID- 29599851 TI - Potential Mechanisms of Mindfulness in Improving Sleep and Distress. AB - The mechanisms of mindfulness-improved sleep quality are not extensively studied. Recently, attention monitoring/awareness and acceptance in mindfulness have been proposed to be the underlying mechanisms that tackle distress and related disorders. The current study tested if acceptance moderated the relationship of awareness with psychological distress and sleep quality, and verified that psychological distress mediated the relationship between mindfulness and sleep quality in a group of community-dwelling healthy adults. Three hundred and sixty four healthy Chinese non-meditators (age 18-65, 59% female) completed a set of online self-reported questionnaires in Chinese via SurveyMonkey. Awareness and acceptance were measured by Observe and Nonreact facets in the Five Facet Mindfulness Questionnaire (FFMQ), respectively. General psychological distress levels and sleep quality were reflected in the global score of the Depression Anxiety and Stress Scales (DASS) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Model 1 and model 8 in the PROCESS macro for SPSS were used to assess the moderation and moderated mediation effects. Increased level of acceptance (Nonreact) weakened the positive relationship between awareness (Observe) and poor sleep quality (beta = -0.0154, p = 0.0123), which was partially mediated through perceived psychological distress (beta = -0.0065, 95% bias-corrected bootstrap CI = -0.0128, -0.0004) in a group of community-dwelling healthy adults. Our findings suggested that awareness and acceptance could be the mechanisms of mindfulness interventions in improving sleep quality, partly via reducing psychological stress. PMID- 29599852 TI - Mindfulness Dampens Cardiac Responses to Motion Scenes of Violence. AB - Mindfulness is linked with improved regulatory processes of attention and emotion. The potential benefits of mindfulness are vast, including more positive emotional states and diminished arousal in response to emotional stimuli. This study aims to expand of the current knowledge of the mechanisms of mindfulness by relating the latter to cardiovascular processes. The paper describes two studies which investigated the relationship of trait mindfulness to self-report measures of emotions elicited during a violent video clip and cardiovascular responses to the clip. Both studies recruited male and female participants, mainly university undergraduate students. The clip was 5-min-long and evoked mainly feelings of tension and disgust. In study 1, we found that higher scores for trait mindfulness were associated with increased scores for valence (r = .370, p = .009), indicating a more positive interpretation of the clip. In study 2, the average heart rate during the clip was lower than during the preceding (p < .05) and following (p < .01) non-exposure conditions. Higher trait mindfulness was related to diminished heart rate reactivity (r = -.364, p = .044) and recovery (r = -.415, p = .020). This latter effect was obtained only when trait anxiety was used as a statistical covariate. Additionally, increased trait mindfulness was accompanied by higher resting heart rate (r = .390, p = .027). These outcomes suggest that mindfulness is linked with reductions in negative feelings evoked by violent motion stimuli. PMID- 29599853 TI - An Investigation of the Factor Structure of the Self-Compassion Scale. AB - The Self-Compassion Scale (SCS) is the most widely used measure of self compassion. The scale is constructed of six factors measuring positive and negative components of compassion. Support for this factor structure has been subject to debate and alternative factor structures have been proposed. We tested the proposed factor structures against existing models of the SCS including one derived from an exploratory factor analysis of our data. Respondents (n = 526) completed the original version of the SCS online at two time points, at baseline (time 1) and 2.5 months later (n = 332, time 2). Exploratory factor analysis (EFA) was carried out on time 1 data and confirmatory factor analyses (CFA) were conducted on time 2 data and retested using time 1 data. The EFA yielded a five factor model. CFA was used to compare the following models: Neff's original six factor correlated and higher-order models; a single-factor, two-factor, five factor model (as suggested by the EFA) and a bi-factorial model. The bi-factorial model was the best fit to the data followed by the six-factor correlated model. Omega indices were calculated and yielded support for the bi-factorial model of SCS. In conclusion, this study supports the use of the six-factor scoring method of the SCS and the use of an overarching self-compassion score. PMID- 29599855 TI - Muscle Activity in Upper-Body Single-Joint Resistance Exercises with Elastic Resistance Bands vs. Free Weights. AB - Elastic resistance bands require little space, are light and portable, but their efficacy has not yet been established for several resistance exercises. The main objective of this study was to compare the muscle activation levels induced by elastic resistance bands versus conventional resistance training equipment (dumbbells) in the upper-body resistance exercises flyes and reverse flyes. The level of muscle activation was measured with surface electromyography in 29 men and women in a cross-over design where resistance loadings with elastic resistance bands and dumbbells were matched using 10-repetition maximum loadings. Elastic resistance bands induced slightly lower muscle activity in the muscles most people aim to activate during flyes and reverse flies, namely pectoralis major and deltoideus posterior, respectively. However, elastic resistance bands increased the muscle activation level substantially in perceived ancillary muscles, that is deltoideus anterior in flyes, and deltoideus medius and trapezius descendens in reverse flyes, possibly due to elastic bands being a more unstable resistance modality. Overall, the results show that elastic resistance bands can be considered a feasible alternative to dumbbells in flyes and reverse flyes. PMID- 29599854 TI - The Role of Parathyroid Hormone and Vitamin D Serum Concentrations in Patients with Cardiovascular Diseases. AB - 25-hydroxyvitamin D (25(OH)D) plays a crucial role in human homeostasis. Its deficiency (vitamin D deficiency-VDD), being common in European population, combined with elevated concentration of parathyroid hormone (PTH), represents a vicious cycle of mechanisms leading to heart failure (HF). Despite several papers published in that field, the effect of VDD and PTH concentration on cardiovascular system remains unequivocal; thus, the aim of the study was to compare these data among HF and non-HF patients being prospectively enrolled into the study during hospital stay in the cardiology ward. Patients with HF had higher PTH concentration (85.0 +/- 52.6 versus 64.5 +/- 31.7, p <= 0.02) compared to non-HF patients. Mean PTH values were associated with the clinical status expressed by the New York Heart Association class (NYHA class) ("0"-66.04, "I" 56.57, "II"-72.30, "III"-85.59, and "IV"-144.37 pg/ml, p <= 0.00004). Interestingly, neither 25(OH)D (31.5 versus 29.7 ng/ml, p <= ns) nor phosphorus (P) (1.23 versus 1.18 mmol/l, p <= ns) nor total calcium (Ca2+) concentration (2.33 versus 2.37 mmol/l, p <= ns) differed among the groups. Reassuming PTH serum concentration in contrary to 25(OH)D, P and Ca2+ are significantly raised among the patients with HF and shows significant relationship with the clinical status expressed by the NYHA class. PMID- 29599856 TI - Influence of Dynamic Neuromuscular Stabilization Approach on Maximum Kayak Paddling Force. AB - The purpose of this study was to examine the effect of Dynamic Neuromuscular Stabilization (DNS) exercise on maximum paddling force (PF) and self-reported pain perception in the shoulder girdle area in flatwater kayakers. Twenty male flatwater kayakers from a local club (age = 21.9 +/- 2.4 years, body height = 185.1 +/- 7.9 cm, body mass = 83.9 +/- 9.1 kg) were randomly assigned to the intervention or control groups. During the 6-week study, subjects from both groups performed standard off-season training. Additionally, the intervention group engaged in a DNS-based core stabilization exercise program (quadruped exercise, side sitting exercise, sitting exercise and squat exercise) after each standard training session. Using a kayak ergometer, the maximum PF stroke was measured four times during the six weeks. All subjects completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire before and after the 6-week interval to evaluate subjective pain perception in the shoulder girdle area. Initially, no significant differences in maximum PF and the DASH questionnaire were identified between the two groups. Repeated measures analysis of variance indicated that the experimental group improved significantly compared to the control group on maximum PF (p = .004; Cohen's d = .85), but not on the DASH questionnaire score (p = .731) during the study. Integration of DNS with traditional flatwater kayak training may significantly increase maximum PF, but may not affect pain perception to the same extent. PMID- 29599857 TI - Modelling and Predicting Backstroke Start Performance Using Non-Linear and Linear Models. AB - Our aim was to compare non-linear and linear mathematical model responses for backstroke start performance prediction. Ten swimmers randomly completed eight 15 m backstroke starts with feet over the wedge, four with hands on the highest horizontal and four on the vertical handgrip. Swimmers were videotaped using a dual media camera set-up, with the starts being performed over an instrumented block with four force plates. Artificial neural networks were applied to predict 5 m start time using kinematic and kinetic variables and to determine the accuracy of the mean absolute percentage error. Artificial neural networks predicted start time more robustly than the linear model with respect to changing training to the validation dataset for the vertical handgrip (3.95 +/- 1.67 vs. 5.92 +/- 3.27%). Artificial neural networks obtained a smaller mean absolute percentage error than the linear model in the horizontal (0.43 +/- 0.19 vs. 0.98 +/- 0.19%) and vertical handgrip (0.45 +/- 0.19 vs. 1.38 +/- 0.30%) using all input data. The best artificial neural network validation revealed a smaller mean absolute error than the linear model for the horizontal (0.007 vs. 0.04 s) and vertical handgrip (0.01 vs. 0.03 s). Artificial neural networks should be used for backstroke 5 m start time prediction due to the quite small differences among the elite level performances. PMID- 29599858 TI - The Effects of Cryotherapy on Knee Joint Position Sense and Force Production Sense in Healthy Individuals. AB - The proprioceptive information received from mechanoreceptors is potentially responsible for controlling the joint position and force differentiation. However, it is unknown whether cryotherapy influences this complex mechanism. Previously reported results are not universally conclusive and sometimes even contradictory. The main objective of this study was to investigate the impact of local cryotherapy on knee joint position sense (JPS) and force production sense (FPS). The study group consisted of 55 healthy participants (age: 21 +/- 2 years, body height: 171.2 +/- 9 cm, body mass: 63.3 +/- 12 kg, BMI: 21.5 +/- 2.6). Local cooling was achieved with the use of gel-packs cooled to -2 +/- 2.5 degrees C and applied simultaneously over the knee joint and the quadriceps femoris muscle for 20 minutes. JPS and FPS were evaluated using the Biodex System 4 Pro apparatus. Repeated measures analysis of variance (ANOVA) did not show any statistically significant changes of the JPS and FPS under application of cryotherapy for all analyzed variables: the JPS's absolute error (p = 0.976), its relative error (p = 0.295), and its variable error (p = 0.489); the FPS's absolute error (p = 0.688), its relative error (p = 0.193), and its variable error (p = 0.123). The results indicate that local cooling does not affect proprioceptive acuity of the healthy knee joint. They also suggest that local limited cooling before physical activity at low velocity did not present health or injury risk in this particular study group. PMID- 29599859 TI - Functional Movements in Japanese Mini-Basketball Players. AB - Functional movement screen (FMS) has been used to establish normative data and determine potential injury risk for young adults and athletes, but there are few data in elementary school-age children. The purpose of this study was to establish fundamental values for the FMS in elementary school-age mini-basketball players. Secondary purposes were to examine relationships between functional movement patterns and age, peak height velocity (PHV), and body mass index (BMI), and to compare functional movement patterns between boys and girls and between individuals with and without a history of injury. The mean composite FMS score was 16.5 +/- 2.2 (16.5 +/- 2.4 for boys, 16.5 +/- 1.7 for girls). The composite FMS score was positively correlated with age (r = .312) and negatively correlated with the BMI (r = - .371). However, the FMS score was not correlated with PHV or with PHV age. The FMS score was not different between boys and girls or between individuals who reported a previous injury and those who did not. However, boys in the mini-basketball teams performed better than girls on the trunk stability push-up and rotary stability tests. Age and the body mass index were significantly associated with better and poorer functional movement, respectively. PMID- 29599860 TI - Can Supplementation of Vitamin D Improve Aerobic Capacity in Well Trained Youth Soccer Players? AB - There is no clear evidence that vitamin D effectively improves physical capacity in high-level athletes. The aim of this study was to confirm that vitamin D supplementation of soccer players during eight-week high-intensity training would have a significant effect on their aerobic capacity. The subjects were divided into two groups: the experimental one that was supplemented with vitamin D (SG, n = 20), and the placebo group (PG, n = 16), not supplemented with vitamin D. All the players were subjected to the same soccer training described as High Intensity Interval Training (HIIT). The data of the vitamin D level, PWC170, lactate threshold (LT) were collected just before and after the intervention. A significant increase in vitamin D concentration (119%) was observed in the supplemented group, while the non-supplemented group showed a decrease of 8.4%. The studied subjects improved VO2max results by 20% in the SG, and by 13% in the PG. The improvement in velocity at the LT was similar in both groups. Results of this study show that vitamin D can have a positive, though moderate, effect on aerobic performance in players subjected to high-intensity training in the form of small-sided games for 8 weeks. PMID- 29599861 TI - The Effects of Aerobic Exercise and Gaming on Cognitive Performance. AB - The purpose of our study was to investigate the effects of video gaming, aerobic exercise (biking), and the combination of these two activities on the domains of cognitive performance: selective attention, processing speed, and executive functioning. The study was a randomized clinical trial with 40 subjects (mean age 23.7 +/- 1.8 years) randomized to one of four thirty-minute conditions: video gaming, biking, simultaneous gaming and biking, and a control condition. Cognitive performance was measured pre and post condition using the Stroop test and Trails B test. A mixed design was utilized. While video gaming, biking, simultaneous gaming and biking conditions improved selective attention and processing speed (p < 0.05), only the bike condition improved the highest order of cognitive performance, executive function (p < 0.01). There were no changes in cognitive performance for the control condition. Previous studies have shown that if tasks approach the limits of attentional capacity there is an increase in the overall chance for errors, known as the dual-task deficit. Simultaneous biking and gaming may have surpassed attentional capacity limits, ultimately increasing errors during the executive function tests of our cognitive performance battery. The results suggest that the fatiguing effects of a combined physically and mentally challenging task that extends after the exercise cessation may overcome the eventual beneficial cognitive effects derived from the physical exercise. PMID- 29599862 TI - Fatigue Responses in Various Muscle Groups in Well-Trained Competitive Male Players after a Simulated Soccer Game. AB - We examined the degree of post-game fatigue and the recovery pattern in various leg and upper-body muscle groups after a simulated soccer game. Well-trained competitive male soccer players (n = 12) participated in the study. The players completed the Copenhagen Soccer Test, a 2 x 45 min simulated soccer protocol, following baseline measures of maximal voluntary contractions of multiple muscle groups and systemic markers of muscle damage and inflammation at 0, 24 and 48 h into recovery. All muscle groups had a strength decrement (p <= 0.05) at 0 h post match with knee flexors (14 +/- 3%) and hip abductors (6 +/- 1%) demonstrating the largest and smallest impairment. However, 24 h into recovery all individual muscles had recovered. When pooled in specific muscle groups, the trunk muscles and knee joint muscles presented the largest decline 0 h post-match, 11 +/- 2% for both, with the performance decrement still persistent (4 +/- 1%, p <= 0.05) for trunk muscles 24 h into recovery. Large inter-player variations were observed in game-induced fatigue and recovery patterns in the various muscle groups. Markers of muscle damage and inflammation peaked 0 h post-match (myoglobin) and 24 h into recovery (creatine kinase), respectively, but thereafter returned to baseline. Intermittent test performance correlated with creatine kinase activity 24 h after the Copenhagen Soccer Test (r = -0.70; p = 0.02). In conclusion, post game fatigue is evident in multiple muscle groups with knee flexors showing the greatest performance decrement. Fatigue and recovery patterns vary markedly between muscle groups and players, yet trunk muscles display the slowest recovery. PMID- 29599863 TI - Aerobic Fitness of Starter and Non-Starter Soccer Players in the Champion's League. AB - To identify individual response patterns in selected aerobic fitness variables of regular starters (ST; N = 7) and non-starters (Non-ST; N = 10), top level professional soccer players were tested for maximal oxygen uptake (VO2max), velocity at 4 mM of lactate (V4), velocity at maximal oxygen uptake (nuVO2max) and oxygen pulse (O2-pulse) in July and December following consecutive periods of fixture congestion. V4 was the only variable that increased significantly in December compared to July (15.1 +/- 0.5 vs. 14.6 +/- 0.5, p = 0.001). There was an almost certain beneficial large mean team change for V4 (ES = 1.2 (0.67; 1.57), 100/0/0), while beneficial mean team changes were less likely for nuVO2max and O2-pulse [ES = 0.31 (-0.08; 0.70), 68/30/2 and ES = 0.24 (0.01; 0.49), 64/36/0, respectively] and unclear for VO2max (ES = 0.02 (-0.31; 0.70), 18/69/13). With the exception of V4 where 10 out of 17 players (7 ST and 3 Non ST) showed positive changes higher than the biological variability, all other variables were characterized by a substantial proportion of changes lower than the biological variability. The present study demonstrated that aerobic fitness variables that require maximal effort may be characterized by greater variability of the individual response pattern compared to that of submaximal aerobic fitness variables irrespective of the accumulated game time. Submaximal aerobic fitness variables appear to be more informative in the physiological evaluation of top level soccer players and this may be an advantage during exposure to periods of consecutive games. PMID- 29599864 TI - Urinary Steroid Profile in Ironman Triathletes. AB - The aim of this study was to determine variations in the urinary steroid profile of triathletes following an Ironman event. A total of 10 male participants (age = 36.0 +/- 1.27 years; body height = 179.29 +/- 10.77 cm; body mass = 74.50 +/- 1.04 kg) completed an Ironman Championship. Urine samples were collected before, immediately after, and 24 hours following the race. Gas chromatography-mass spectrometry (GC/MS) was used to detect and quantify catabolic and anabolic hormones: Androsterone, Dehydroepiandrosteone (DHEA), Androstenedione and Testosterone (T), Betaestradiol, Estrone, Progesterone, Cortisol (C), Cortisone, Tetrahydrocortisol (THE) and Tetrahydrocortisone (THF). These were measured in their glucuroconjugated and free forms. Androsterone (3297.80 +/- 756.83 vs. 2154.26 +/- 1375.38), DHEA (47.80 +/- 19.21 vs. 32.62 +/- 15.96) and Beta estradiol (59.36 +/- 11.7 vs. 41.67 +/- 10.59) levels decreased after the event. The significant decrease of DHEA (47.80 +/- 19.21 vs. 32.11 +/- 14.03) remained at 24 hours. Cortisol (200.38 +/- 56.60 vs. 257.10 +/- 74.00) and THE (238.65 +/- 81.55 vs. 289.62 +/- 77.13) increased after exercise and remained elevated 24 hours later (200.38 +/- 56.60 vs. 252.48 +/- 62.09; 238.65 +/- 81.55 vs. 284.20 +/- 66.66). The following anabolic/catabolic ratios fell after exercise: T/C (0.85 +/- 0.54 vs. 0.54 +/- 0.29), T/THE (0.66 +/- 0.29 vs. 0.40 +/- 0.08), T/THE+THF (0.38 +/- 0.17 vs. 0.24 +/- 0.06), DHEA/THE (0.22 +/- 0.05 vs. 0.12 +/- 0.05), DHEA/THF (0.34 +/- 0.02 vs. 0.21 +/- 0.01) and DHEA/THE+THF (0.12 +/- 0.02 vs. 0.08 +/- 0.03). The steroid profile showed that athletes were fatigued after finishing the competition and a catabolic state remained 24 hours later. PMID- 29599865 TI - Effect of Compression Garments on Physiological Responses After Uphill Running. AB - Limited practical recommendations related to wearing compression garments for athletes can be drawn from the literature at the present time. We aimed to identify the effects of compression garments on physiological and perceptual measures of performance and recovery after uphill running with different pressure and distributions of applied compression. In a random, double blinded study, 10 trained male runners undertook three 8 km treadmill runs at a 6% elevation rate, with the intensity of 75% VO2max while wearing low, medium grade compression garments and high reverse grade compression. In all the trials, compression garments were worn during 4 hours post run. Creatine kinase, measurements of muscle soreness, ankle strength of plantar/dorsal flexors and mean performance time were then measured. The best mean performance time was observed in the medium grade compression garments with the time difference being: medium grade compression garments vs. high reverse grade compression garments. A positive trend in increasing peak torque of plantar flexion (60o.s-1, 120o.s-1) was found in the medium grade compression garments: a difference between 24 and 48 hours post run. The highest pain tolerance shift in the gastrocnemius muscle was the medium grade compression garments, 24 hour post run, with the shift being +11.37% for the lateral head and 6.63% for the medial head. In conclusion, a beneficial trend in the promotion of running performance and decreasing muscle soreness within 24 hour post exercise was apparent in medium grade compression garments. PMID- 29599866 TI - Impact of Official Matches on Soccer Referees' Power Performance. AB - The evaluation of match officials' neuromuscular performance is now an important consideration and the vertical jump test is considered suitable for assessing lower limb power, partly because it is directly related to refereeing. The aim of this study, therefore, was to determine the effect of soccer matches on match officials' vertical jump performance by assessing various biomechanical variables. Eighteen field referees (FRs) and 36 assistant referees (ARs) who officiated in 18 official matches participated in this study. Before the match, at half time and immediately after the match, officials performed two countermovement jumps. Flight phase time (FT), maximum force production (MFpropulsion), time to production of maximum force (TMFpropulsion), production of maximum power (MP), maximum landing force (MFlanding) and time to stabilization (TTS) were calculated for all jumps. There was a tendency for match officials' jumping performance to improve after matches than beforehand (FR: effect size (ES) = 0.19 +/- 0.36, possibly trivial; AR: ES = 0.07 +/- 0.17, likely trivial). There were also likely small and very likely moderate differences between FRs' MP in pre-match and half-time jumps (ES = 0.46 +/- 0.47) and in their pre- and post-match jumps (ES = 0.71 +/- 0.48). These results indicate that refereeing soccer matches does not reduce vertical jump performance; the subsequent neuromuscular fatigue is not sufficient to affect landing technique. PMID- 29599867 TI - Variance in Prominence Levels and in Patterns of Passing Sequences in Elite and Youth Soccer Players: A Network Approach. AB - The aim of this study was to quantify the prominence levels of elite and highly competitive young soccer players. This study also analyzed the variation in general network properties at different competitive levels and periods of the season. A total of 132 matches, played by 28 teams during the 2015/2016 season, were analyzed. The results revealed significant differences in the composition of general network measures considering the competitive level (p = 0.002; ES = 0.077) and according to the location of the match (p = 0.001; ES = 0.147). There were positive correlations between network density and the final score (rho = 0.172) and negative correlations between network density and goals conceded (rho = - 0.300). Significant differences in the composite of centralities were found between positions (p = 0.001; ES = 0.293; moderate effect) and the location of the match (p = 0.001; ES = 0.013; no effect). This revealed that the general properties of cooperation increased with the competitive level, improved during the middle of the season and were better in home matches. Midfielders were most prominent players in elite and U19 teams in the mid-season and central defenders had the most prominent centralities in U17 and U15 during the early and late periods of the season. PMID- 29599868 TI - Strength and Conditioning Coaches' Application of the Session Rating of Perceived Exertion Method of Monitoring within Professional Rugby Union. AB - Session rating of perceived exertion (session-RPE) is a method of monitoring and managing training loads. The purpose of this study was to research how and for what purpose strength and conditioning (S&C) coaches implement this monitoring method within professional rugby union. The study also aimed to assess if S&C coaches found this monitoring method to be valid and effective. An online survey containing 24 fixed response questions was used to assess how S&C coaches applied the session-RPE method. The survey was piloted with expert researchers and practitioners in the area of session-RPE prior to distribution and alterations were made to the survey based on the experts' feedback. Twenty S&C coaches working with professional rugby union clubs in Ireland, England, Scotland and Wales completed the survey. The coaches' responses indicated that the majority found the session-RPE to be a valid and effective monitoring method. While some good implementation practices were identified, not all of the coaches adhered to these guidelines which may impact on the accuracy of the collected data. For example, 30% of coaches do not collect the RPE for every session that a player does per week limiting the use of the session-RPE variables cumulative training load, training monotony, training strain and acute:chronic load ratio. S&C coaches within rugby should consider using session-RPE as a method of monitoring and implement the method in a manner reflective of research findings to enhance the potential applications of this system in maximising adaptations and minimising the risk of injury. PMID- 29599869 TI - Variables that Predict Serve Efficacy in Elite Men's Volleyball with Different Quality of Opposition Sets. AB - The objective of this study was to determine the variables that predicted serve efficacy in elite men's volleyball, in sets with different quality of opposition. 3292 serve actions were analysed, of which 2254 were carried out in high quality of opposition sets and 1038 actions were in low quality of opposition sets, corresponding to a total of 24 matches played during the Men's European Volleyball Championships held in 2011. The independent variables considered in this study were the serve zone, serve type, serving player, serve direction, reception zone, receiving player and reception type; the dependent variable was serve efficacy and the situational variable was quality of opposition sets. The variables that acted as predictors in both high and low quality of opposition sets were the serving player, reception zone and reception type. The serve type variable only acted as a predictor in high quality of opposition sets, while the serve zone variable only acted as a predictor in low quality of opposition sets. These results may provide important guidance in men's volleyball training processes. PMID- 29599870 TI - Effect of Two Different Types of Olympic Rotation Order on Cardiovascular and Metabolic Variables in Men's Artistic Gymnastics. AB - The rotation sequence-order differs from a gymnast to another according to the draw at the time of the qualifying competitions in men's artistic gymnastics. Only the six best gymnasts start on the floor exercises, the others could start on any of the other five apparatuses. It has been demonstrated that some gymnastics events are physiologically less taxing than others; hence some gymnasts could experience lower and/or higher levels of cardiovascular and metabolic stress compared to others, depending on the apparatus they start with. In this regard, the objective of this investigation was to compare cardiovascular and metabolic variables between two different types of Olympic rotation-order; one began with the floor exercises and the other began with the pommel horse. Six elite male gymnasts took part in this investigation. Heart rates, synchronized with real-time video acquisition, as well as capillary lactate concentration following each apparatus routine were monitored. Cardiovascular and metabolic stresses were significantly higher when gymnasts started their rotation with the pommel horse in all apparatuses except the pommel horse. The floor exercises' score was significantly affected when gymnasts ended up their competition on this apparatus. As a conclusion, starting gymnastics' competition on the floor exercises implicates less cardiovascular and metabolic stress associated with better performance compared with the other rotation order. As a matter of fact, best gymnasts who start on this apparatus could have a slight advantage compared with the other athletes. PMID- 29599871 TI - Effects of Different Post-Activation Potentiation Warm-Ups on Repeated Sprint Ability in Soccer Players from Different Competitive Levels. AB - This study aimed to compare the effects of a traditional warm-up with two post activation potentiation (PAP) warm-up strategies on the repeated sprint ability (RSA) of soccer players from national (NL) and regional (RL) competitive levels. Sixteen young players (NL, n = 8, age = 20.7 +/- 1.4 y, body mass = 68.5 +/- 7.0 kg, body height = 177.4 +/- 5.2 cm; RL, n = 8, age = 20.8 +/- 1.0 y, body mass = 68.7 +/- 4.0 kg, body height = 176.6 +/- 5.6 cm) were recruited to complete a traditional warm-up (CONTROL), a PAP warm-up incorporating squats with a load (~60% 1RM) that allowed a high speed (1 m/s) of movement and a high number of repetitions (PAP-1), and a PAP warm-up with a load (~90% 1RM) that allowed a moderate speed (0.5 m/s) of movement and a reduced number of repetitions (PAP 0.5). A RSA test (six 20-m sprints with 20 s of recovery) was performed 5 min after the PAP warm-up to assess the effects of the different protocols on the fastest sprint (RSAb) and the mean time of all sprints (RSAm). A meaningful improvement of RSA performance was observed with PAP-0.5, attaining a large effect on NL (RSAb, ES = -1.5; RSAm, ES = -1.3) and only a small effect on RL athletes (RSAb and RSAm, ES = -0.2). Moreover, when each RSA sprint performance was compared between NL and RL players, after PAP-0.5 greater performance for all sprints was observed in the NL players. Therefore, adding a heavy strength-based conditioning exercise during the warm-up prior to a RSA test may induce significant performance improvements in NL, but only small effects in RL players. PMID- 29599872 TI - Responsiveness of the Countermovement Jump and Handgrip Strength to an Incremental Running Test in Endurance Athletes: Influence of Sex. AB - The present study analyzed the acute effects of an incremental running test on countermovement jump (CMJ) and handgrip strength performance in endurance athletes, considering the effect of post-exercise recovery time and sex. Thirty three recreationally trained long-distance runners, 20 men and 13 women, participated voluntarily in this study. The participants performed the Leger test, moreover, the CMJ and handgrip strength tests were carried out before and after the running test and during different stages of recovery (at the 1st min of recovery (posttest1), 5th min of recovery (posttest2), and 10th min of recovery (posttest3)). Two-way analysis of variance revealed a significant improvement in the CMJ (pre-posttest1, p = 0.001) and handgrip strength (pre-posttest2, p = 0.017) during recovery time. The Pearson's Chi-2 test showed no significant relationship (p >= 0.05) between sex and post-activation potentiation (PAP). A linear regression analysis pointed to heart rate recovery as a predictive factor of CMJ improvement (PAP). In conclusion, despite significant fatigue reached during the Leger test, the long-distance runners did not experience an impaired CMJ and handgrip strength performance, either men or women, achieving an improvement (PAP) in posttest conditions. The results obtained showed no significant relationship between sex and PAP. Moreover, significant effect of recovery after running at high intensity on CMJ performance and handgrip strength was found. Finally, the data suggest that PAP condition can be predicted by heart rate recovery in endurance runners. PMID- 29599873 TI - Physical Performance Comparison between Under 15 Elite and Sub-Elite Soccer Players. AB - The aim of this study was to compare the physical performance profile among young soccer players of different competitive levels. Two teams of elite (n = 22) and sub-elite (n = 22) soccer players at national (highly skilled) and regional (moderately skilled) level were recruited in the study. All participants were tested using a modified Illinois change of direction speed test, a T-drill with and without a ball, a countermovement jump, and a 10-m sprint. The analysis revealed significant differences in favor of elite players in sprint (d = 1.54, large) and vertical jump (d = 2.03, very large) outcomes, while no differences were observed in both modified Illinois change of direction speed (d = 0.16, trivial) and T-drill (d = 0.20, small) tests between the groups. The ability to change direction and speed with and without a ball was found not to be suitable enough to highlight the difference among youth players with moderate-to-high level of play. In conclusion, multi-testing approach based on task-related power should include vertical jump and sprint performance to delineate players of a higher level. PMID- 29599874 TI - Validation and Reliability of the Korean Version of the Sport Anxiety Scale-2. AB - The main purpose of the present study was to examine the validation and reliability of the Korean version of the Sport Anxiety Scale (SAS-2Kr) by evaluating its factorial invariance across gender. A total of 303 Korean collegiate athletes (198 males and 105 females) from 9 sports participated in the study, and they completed the demographic questionnaire and the SAS-2Kr containing 15 items to measure multidimensional trait anxiety and individual differences in the cognitive and somatic anxiety experienced by athletes. The results of this study indicated that the construct validity in the SAS-2Kr was well established in that the values of the standardized factor loadings, composite reliability, and average variance extracted values were above the recommended cutoff points. The multiple-sample confirmatory factor analyses showed the SAS-2Kr could be generalizable across gender in college samples. The results also indicated that the SAS-2Kr supported the original 3-factor model of SAS-2 in English consisting of somatic anxiety, worry, and concentration disruption, and thus this study provides useful information for researchers to understand the athletes' tendency to experience anxiety reactions in sport situations. Suggestions for future research on competitive trait anxiety are provided in the discussion section.

The sample was composed of 80 players, divided into four levels of expertise (first national category, second national category, autonomous regional level and provincial level). The Squash Performance Evaluation Tool was used for recording the level of decision-making and execution. The results revealed that reading of the context of the game improved as the level of the player's expertise of both the return shot and the drop shot increased. The correlation between correct decision-making and better quality execution for both the return shot and the drop shot in squash also improved with the player's level of expertise. According to these results, improvements in situational tactical principles and the application of tactical principles, correct decision-making and high-quality execution are essential to develop the athletic performance level among squash players. PMID- 29599876 TI - Competition Field Perceptions of Table-tennis Athletes and their Performance. AB - The distinction between positive and negative perceptions is fundamental in perception models. The purpose of this study was to investigate the correlation between field perceptions of table tennis players and the outcome (net result) during the matches in a competition. Experimental data were collected from 10 elite table tennis players and analysed. The results addressed the following three competition field perceptions: (1) before the service, the player's positive perceptions had significant effect on the positive outcome (winning rate) of that service; (2) the perception after the net result of the previous service increased the positive outcome of the next service, and (3) the player's positive/negative perception during the matches affected the win/loss outcome of that competition. In conclusion, the player's positive perceptions enhanced their winning rate during table tennis competitions. Therefore, during the training program, coaches need to develop positive perceptions and strengthen the psychological quality of table tennis players. PMID- 29599877 TI - Motivational Climate Sport Youth Scale: Measurement Invariance Across Gender and Five Different Sports. AB - The aim of this study was to analyze the psychometric properties of the Portuguese version of the Motivational Climate Sport Youth Scale (MCSYSp) and invariance across gender and different sports (swimming, soccer, handball, basketball, futsal). A total of 4,569 athletes (3,053 males, 1,516 females) from soccer (1,098), swimming (1,049), basketball (1,754), futsal (340), and handball (328) participated in this study, with ages between 10 and 20 years (M = 15.13; SD = 1.95). The results show that the original model (two factors/12 items) did not adjust to the data in a satisfactory way; therefore, it was necessary to change the model by removing four items (two from each factor). Subsequently, the model adjusted to the data in a satisfactory way (chi2 = 499.84; df = 19; chi2/df = 26.30; p < .001; SRMR = .037; TLI = .923; CFI = .948; RMSEA = .074; IC90% .069 .080) and was invariant by gender and team sports (soccer, handball, basketball, futsal) (DeltaCFK<=.01); however, it was not invariant between swimming and team sports (soccer, handball, basketball, futsal) (DeltaCFI >= .01). In conclusion, the MCSYSp (two factors/eight items) is a valid and reliable choice that is transversal not only to gender, but also to the different studied team sports to measure the perception of the motivational climate in athletes. Future studies can research more deeply the invariance analysis between individual sports to better understand the invariance of the model between individual and team sports. PMID- 29599878 TI - Understanding Trail Runners' Activity on Online Community Forums: An Inductive Analysis of Discussion Topics. AB - Recreational trail runners often participate in online community forums where they can freely read posted messages, join discussions and/or introduce new discussion topics. This tool can enhance learning as runners connect with other trail runners and reflect on how they can better organize their own practice. Studying forum activity would provide greater insight into the relationship between field practice and dedicated forums. The aim of this study was therefore to detect the topics discussed online by trail runners in order to understand how they collectively look for solutions that help them adapt to issues that emerge during actual practice. The discussion topics (n = 171) on the forum hosted by the Raidlight brand were examined using inductive content analysis, which distinguished two general dimensions. The first dimension was training and had four first-order themes (i.e., "specific trail running sessions", "complementary trail running sessions". "training plans" and "specific questions about races") grouped into two second-order themes (i.e., "training session contents" and "structure and schedule"). The second dimension was health and had seven first order themes (i.e., "tendinitis", "muscle issues", "foot issues", "sprains and fractures", "pain", "physiology" and "substances and practitioners") grouped into two second-order themes (i.e., "pain and injury" and "prevention"). The results indicate that the issues that trail runners discuss on forums are significant and that the successions of questions and solutions are a fruitful means for building, enriching and adjusting their activity as they cope with constraints. As a practical consequence, suggestions for improving such online platforms are made. PMID- 29599879 TI - A multi-centre evaluation of oral cancer in Southern and Western Nigeria: an African oral pathology research consortium initiative. AB - Introduction: Oral cancer is a leading cause of cancer deaths among African populations. Lack of standard cancer registries and under-reporting has inaccurately depicted its magnitude in Nigeria. Development of multi-centre collaborative oral pathology networks such as the African Oral Pathology Research Consortium (AOPRC) facilitates skill and expertise exchange and fosters a robust and systematic investigation of oral diseases across Africa. Methods: In this descriptive cross-sectional study, we have leveraged the auspices of the AOPRC to examine the burden of oral cancer in Nigeria, using a multi-centre approach. Data from 4 major tertiary health institutions in Western and Southern Nigeria was generated using a standardized data extraction format and analysed using the SPSS data analysis software (version 20.0; SPSS Inc. Chicago, IL). Results: Of the 162 cases examined across the 4 centres, we observed that oral squamous cell carcinomas (OSCC) occurred mostly in the 6th and 7th decades of life and maxillary were more frequent than mandibular OSCC lesions. Regional variations were observed both for location, age group and gender distribution. Significant regional differences was found between poorly, moderately and well differentiated OSCC (p value = 0.0071). Conclusion: A multi-centre collaborative oral pathology research approach is an effective way to achieve better insight into the patterns and distribution of various oral diseases in men of African descent. The wider outlook for AOPRC is to employ similar approaches to drive intensive oral pathology research targeted at addressing the current morbidity and mortality of various oral diseases across Africa. PMID- 29599880 TI - ? AB - Neonatal thrombopenia is the most common hemostatic abnormality in newborns. It is defined as a platelet count below 150.000/mm3. 40% of newborns to mothers with a history of autoimmune thrombopenia are at risk of developing neonatal thrombopenia while 10-15% of them are at risk of developing severe thrombopenia. We here report the case of a 20 days old newborn to mother splenectomized for idiopathic thrombopenic purpura in order to highlight the relationship between the severity of maternal disease and the severity of the neonatal thrombopenia and thereby to avoid the risk of intracranial hemorrhage resulting in death or neurological sequelae.

AB - Introduction: X-linked adrenoleukodystrophy (X-ALD) is a severe neurodegenerative disease, due to mutations in the ABCD1 gene. It manifests as a damage to the central and peripheral nervous system, adrenal insufficiency and testicular damage in children. Diagnosis is based on the determination of long-chain saturated fatty acids. Early diagnosis is essential because it defines treatment accessibility according to disease stage. Methods: We implemented a X-ALD diagnostic test program in Morocco at the Children's Hospital and at the Central Laboratory for inherited and metabolic diseases in Rabat. The program was based around three priorities, namely: the recruitment of patients, diagnosis and awareness. Diagnosis is based on three protocols: a protocol for symptomatic cases, a protocol for asymptomatic cases and a protocol for heterozygous women. Results: During the first three years after implementation of our X-ALD diagnostic test program, we diagnosed the disease in seven families, with nine boys and three heterozygous women. All children were diagnosed with demyelinating brain. All heterozygous women were asymptomatic. Different symptom-based therapies were established. Conclusion: X-ALD is a rare disease. Our diagnostic program has helped to diagnose a significant number of cases, hence its importance. Campaigns focused on raising awareness among health care professionals will enable a better understanding of the disease and a more accurate diagnosis as well as to improve access to health care for a higher number of patients. PMID- 29599884 TI - Prevalence of chronic viral hepatitis infections in Karaj, Iran. AB - Introduction: Viral hepatitis is challenging for health and blood safety. Studies carried out on blood donors can help find the frequency and trending of hepatitis B and C infections in a community and also safety of donation. The study aim is to determine the prevalence of HBV and HCV in Karaj blood donors over a four year period between 2010 to 2013. Methods: This study reports the results of a cross sectional seroepidemiological study of hepatitis B and C in blood donors. Data on hepatitis infection and demographic characteristics of donors were gathered from blood donor registries. Frequency of hepatitis infections were described with 95% confidence interval. Chi square and logistic regression were used for analysis. Results: The frequency of HBV and HCV infection in Karaj blood donors was 0.40% and 0.18% respectively. In first time donors, HBV and HCV positivity risk was respectively 3.59 and 4.8 fold in people with primary education (OR=3.59; 95% CI between 2.68-4.80) comparing to academic level. Frequency of hepatitis B has decreased significantly (P<0.001) during study period but frequency of Hepatitis C has not changed significantly. Conclusion: The frequencies of HBV and HCV infection in Karaj blood donor population is low. There are equal infection rates within both genders. This must be considered in controlling transmission of infection in this area. PMID- 29599885 TI - [Narrow lumbar channel due to epidural lipomatosis: case report and literature review]. AB - Epidural lipomatosis is characterized by the abnormal accumulation of non encapsulated grease in the epidural space. Although rare, it is a possible cause of lombosciatica or narrow lumbar channel. It is often associated with contributing factors such as prolonged corticosteroid therapy or obesity. We report the case of a patient presenting with disabling lombosciatalgias. Radiological evaluation confirmed the diagnosis of compressive epidural lipomatosis. Patient's evolution was favorable after surgical decompression. PMID- 29599886 TI - [Malignant transformation of chronic osteomyelitis: a case report]. AB - Malignant transformation of chronic osteomyelitis is a rare and late complication which mainly occurs at the level of the edges of a fistulous tract with extension and infiltration to the surrounding soft tissues and more rarely to bones. We here report the case of Mr N.J. aged 67 years, followed up for chronic osteomyelitis of the right femur fistulized to the skin and evolving since the age of 16 years. He presented with secerning fistulas. Imaging examination showed pathologic fracture due to osteolytic lesion of the lower extremity of the right femur associated with poorly defined intra-medullary collection of fluid measuring 8 cm along its longer axis. The patient underwent surgical resection of the fistulas with complete evacuation and curettage of the bone cavity. Pathological examination showed differentiated keratinising squamous cell carcinoma, infiltrating the fistulous tract and extending to the soft parts and to the lower extremity of the right femur. Staging was negative. Disarticulation of the HIP was performed. At two-years follow-up the patient was doing well without local recurrence or distant metastasis. Initial treatment of chronic osteomyelitis is essential to prevent alarming complications. Amputation is the treatment of choice in patients with malignant transformation of chronic osteomyelitis in particular to squamous cell carcinoma, as in the case of our patient, in order to to prevent secondary involvement.

AB - Pepper's syndrome is a neuroblastoma that metastasizes to the liver. It affects infants younger than six months of age. It can regress spontaneously and is associated with a favorable prognosis in 80% of cases. Given its rarity, we here report two cases of Pepper's syndrome observed at the Charles de Gaulle university pediatric hospital center, Ouagadougou (Burkina Faso). Our study involved two female infants in whom the disease manifested as an increase in abdominal volume, hepatomegaly and signs of respiratory distress. Ultrasound enabled diagnosis, which was based on the nodular appearance of the liver in both cases and determination of the primary tumor in one case. Urinary catecholamine test confirmed the diagnosis in one case. Both patients died from complications related to liver compression, chemotherapy (in one of the cases) and lack of treatment (in the other case).

It is characterized of three different components: muscular, vascular and greasy. Their distribution is variable. Diagnosis is based on the identification of the intratumoral greasy component on CT scan and MRI. In exceptional circumstances, this tumor may be aggressive with locoregional and venous extension (renal vein and inferior vena cava). We here report the case of a 37-year old patient with voluminous renal angiomyolipoma extending to the renal vein. PMID- 29599889 TI - Evolution of HIV prevalence and behavioral factors among MSM in Togo between 2011 and 2015. AB - Introduction: The aim of this study was to assess sexual behavior and measure HIV prevalence among MSM in 2015, in Togo. Methods: We conducted a cross-sectional study from February to March 2015 in nine major cities of Togo. The respondent driven sampling method was used to recruit MSM. Behavioral data were collected by interviewer-administered questionnaires. The blood tests were then carried out among MSM to assess their HIV status. Data were inputted into an Epidata database and exported to STATA(r) 9.0 for analysis. Qualitative variables were compared using the chi-2. Results: A total of 496 MSM were involved in this study, with 43.35% in the capital, Lome. Over the past 12 months, 88.9% of MSM had had sexual intercourse with men and 24.1% of them had had sex with women. The last sexual intercourse was with a casual partner among 52.9% of MSM. During the last 30 days preceding the survey, 68.5% of MSM had regularly used a condom during active anal intercourse and 71.9% had used it during passive anal intercourse. The national prevalence rate of HIV among MSM was 13.0%. The factors associated with HIV infection were age of MSM OR = 5.30 [1.85-15.1], HIV testing history OR = 2.63 [1.18-5.87] and the city of residence of MSM OR = 5.56 [2.90-10.64]. Conclusion: This study confirms that HIV prevalence among MSM is five times higher than in the general population (13% vs 2.5%). Thus, the need to rethink HIV sensitization and prevention strategies targeting hidden and stigmatized populations such as MSM. PMID- 29599890 TI - [Moya moya disease: a rare cause of ischemic stroke in children: about a case]. AB - Moya moya disease is an angiogenic disease characterized by the narrowing of the distal internal carotid artery extending to the proximal segments of the middle and anterior cerebral arteries, inducing collateral vessels formation. These vessels come from the collateral parenchymal vessels, the perforating vessels, leptomeningeal vessels and other transdural anastomoses. These collateral vessels have a characteristic appearance on angiography, forming a cloud of smoke: net like moyamoya. Its etiology is still poorly understood. Moyamoya disease accounts for 10-15% of the causes of stroke, with 2 age peaks at which its occurrence is more frequent: children around 5 years old and adults around 40 years old. Its evolution can be slow with intermittent symptoms or fulminant with fast neurological deterioration. The current data show the role of surgery as the gold standard for the treatment of moyamoya syndrome, in particular in patients with progressive and recurrent symptoms. PMID- 29599891 TI - [Alobar holoprosencephaly associated with diabetes insipidus and hypothyroidism in a 10-month old infant]. AB - Holoprosencephaly (HPE) is a serious brain malformation due to a failure of medial forebrain cleavage. This is an abnormality which is more often associated with craniofacial malformations, psychomotor development delay, diabetes insipidus and variable endocrine disorders. It is due to different causes including chromosomal abnormalities (trisomy 13, 18)and polymalformative syndromes (CHARGE Syndrome). Diagnosis is based on brain imaging. A few rare cases have been described in the literature. We here report the case of alobar HPE in a 10-month old infant. Diagnosis was based on cerebral CT scan performed due to delayed psychomotor development and in the absence of visible malformations. Endocrine assessment allowed to detect central diabetes insipidus and central hypothyroidism, probably of hypothalamic origin. PMID- 29599892 TI - Thioredoxin-1 Protects Bone Marrow-Derived Mesenchymal Stromal Cells from Hyperoxia-Induced Injury In Vitro. AB - Background: The poor survival rate of mesenchymal stromal cells (MSC) transplanted into recipient lungs greatly limits their therapeutic efficacy for diseases like bronchopulmonary dysplasia (BPD). The aim of this study is to evaluate the effect of thioredoxin-1 (Trx-1) overexpression on improving the potential for bone marrow-derived mesenchymal stromal cells (BMSCs) to confer resistance against hyperoxia-induced cell injury. Methods: 80% O2 was used to imitate the microenvironment surrounding-transplanted cells in the hyperoxia induced lung injury in vitro. BMSC proliferation and apoptotic rates and the levels of reactive oxygen species (ROS) were measured. The effects of Trx-1 overexpression on the level of antioxidants and growth factors were investigated. We also investigated the activation of apoptosis-regulating kinase-1 (ASK1) and p38 mitogen-activated protein kinases (MAPK). Result: Trx-1 overexpression significantly reduced hyperoxia-induced BMSC apoptosis and increased cell proliferation. We demonstrated that Trx-1 overexpression upregulated the levels of superoxide dismutase and glutathione peroxidase as well as downregulated the production of ROS. Furthermore, we illustrated that Trx-1 protected BMSCs against hyperoxic injury via decreasing the ASK1/P38 MAPK activation rate. Conclusion: These results demonstrate that Trx-1 overexpression improved the ability of BMSCs to counteract hyperoxia-induced injury, thus increasing their potential to treat hyperoxia-induced lung diseases such as BPD. PMID- 29599893 TI - Pretreatment with Shuanghe-Tang Extract Attenuates Postischemic Brain Injury and Edema in a Mouse Model of Stroke: An Analysis of Medicinal Herbs Listed in Dongui Bogam. AB - Aim: Although stroke is among the leading causes of death and long-term disability, there are few effective treatments for limiting the severity of neurological sequelae. We evaluated the effects of 29 medicinal herbs listed in the Pung chapter of the 17th century Korean medical text Dongui Bogam on stroke symptoms in a mouse model of cerebral ischemia. Methods: Focal cerebral ischemia was induced via photothrombosis. Infarct volume, brain edema, and neurological deficits were evaluated. Immunofluorescence staining for tight junction proteins and aquaporin 4 (AQP4) was performed following ischemic injury. Results: Based on our initial findings, we examined the effects of two prescriptions in which the candidate herbs comprised more than 60% of the total formula: Shuanghe-tang and Zengsunsiwu-tang. Pretreatment with Shuanghe-tang significantly reduced infarct volume, decreased blood-brain barrier (BBB) breakdown, attenuated edema, and improved neurological and motor functions in a dose-dependent manner (30, 100, and 300 mg/kg), while no such effects were observed in mice pretreated with Zengsunsiwu-tang. Immunohistochemical analysis revealed significant increases in ipsilateral occludin and zonula occludens 1 (ZO-1) expression in Shuanghe-tang pretreated mice, as well as increased AQP4 immunofluorescence. Conclusions: These results indicate that Shuanghe-tang may protect against brain injury and promote recovery of neurological function following ischemia.

PMID- 29599896 TI - Myeloid Heme Oxygenase-1 Regulates the Acute Inflammatory Response to Zymosan in the Mouse Air Pouch. AB - Heme oxygenase-1 (HO-1) is induced by many stimuli to modulate the activation and function of different cell types during innate immune responses. Although HO-1 has shown anti-inflammatory effects in different systems, there are few data on the contribution of myeloid HO-1 and its role in inflammatory processes is not well understood. To address this point, we have used HO-1M-KO mice with myeloid restricted deletion of HO-1 to specifically investigate its influence on the acute inflammatory response to zymosan in vivo. In the mouse air pouch model, we have shown an exacerbated inflammation in HO-1M-KO mice with increased neutrophil infiltration accompanied by high levels of inflammatory mediators such as interleukin-1beta, tumor necrosis factor-alpha, and prostaglandin E2. The expression of the degradative enzyme matrix metalloproteinase-3 (MMP-3) was also enhanced. In addition, we observed higher levels of serum MMP-3 in HO-1M-KO mice compared with control mice, suggesting the presence of systemic inflammation. Altogether, these findings demonstrate that myeloid HO-1 plays an anti inflammatory role in the acute response to zymosan in vivo and suggest the interest of this target to regulate inflammatory processes. PMID- 29599894 TI - Emerging Players at the Intersection of Chondrocyte Loss of Maturational Arrest, Oxidative Stress, Senescence and Low-Grade Inflammation in Osteoarthritis. AB - The prevalence of Osteoarthritis (OA) is increasing because of the progressive aging and unhealthy lifestyle. These risk factors trigger OA by removing constraints that keep the tightly regulated low turnover of the extracellular matrix (ECM) of articular cartilage, the correct chondrocyte phenotype, and the functionality of major homeostatic mechanisms, such as mitophagy, that allows for the clearance of dysfunctional mitochondria, preventing increased production of reactive oxygen species, oxidative stress, and senescence. After OA onset, the presence of ECM degradation products is perceived as a "danger" signal by the chondrocytes and the synovial macrophages that release alarmins with autocrine/paracrine effects on the same cells. Alarmins trigger innate immunity in the joint, with important systemic crosstalks that explain the beneficial effects of dietary interventions and improved lifestyle. Alarmins also boost low grade inflammation: the release of inflammatory molecules and chemokines sustained by continuous triggering of NF-kappaB within an altered cellular setting that allows its higher transcriptional activity. Chemokines exert pleiotropic functions in OA, including the recruitment of inflammatory cells and the induction of ECM remodeling. Some chemokines have been successfully targeted to attenuate structural damage or pain in OA animal models. This represents a promising strategy for the future management of human OA. PMID- 29599897 TI - Reactive Oxygen Species in Chronic Obstructive Pulmonary Disease. AB - Chronic obstructive pulmonary disease (COPD) includes chronic bronchitis and emphysema. Environmental exposure, primarily cigarette smoking, can cause high oxidative stress and is the main factor of COPD development. Cigarette smoke also contributes to the imbalance of oxidant/antioxidant due to exogenous reactive oxygen species (ROS). Moreover, endogenously released ROS during the inflammatory process and mitochondrial dysfunction may contribute to this disease progression. ROS and reactive nitrogen species (RNS) can oxidize different biomolecules such as DNA, proteins, and lipids leading to epithelial cell injury and death. Various detoxifying enzymes and antioxidant defense systems can be involved in ROS removal. In this review, we summarize the main findings regarding the biological role of ROS, which may contribute to COPD development, and cytoprotective mechanisms against this disease progression. PMID- 29599898 TI - The Effects of Ibogaine on Uterine Smooth Muscle Contractions: Relation to the Activity of Antioxidant Enzymes. AB - Ibogaine is an indole alkaloid originally extracted from the root bark of the African rainforest shrub Tabernanthe iboga. It has been explored as a treatment for substance abuse because it interrupts drug addiction and relieves withdrawal symptoms. However, it has been shown that ibogaine treatment leads to a sharp and transient fall in cellular ATP level followed by an increase of cellular respiration and ROS production. Since contractile tissues are sensitive to changes in the levels of ATP and ROS, here we investigated an ibogaine-mediated link between altered redox homeostasis and uterine contractile activity. We found that low concentrations of ibogaine stimulated contractile activity in spontaneously active uteri, but incremental increase of doses inhibited it. Inhibitory concentrations of ibogaine led to decreased SOD1 and elevated GSH-Px activity, but doses that completely inhibited contractions increased CAT activity. Western blot analyses showed that changes in enzyme activities were not due to elevated enzyme protein concentrations but posttranslational modifications. Changes in antioxidant enzyme activities point to a vast concentration-dependent increase in H2O2 level. Knowing that extracellular ATP stimulates isolated uterus contractility, while H2O2 has an inhibitory effect, this concentration-dependent stimulation/inhibition could be linked to ibogaine related alterations in ATP level and redox homeostasis. PMID- 29599900 TI - Metabolomics: From liver chiromancy to personalized precision medicine in advanced chronic liver disease. AB - Currently there is a lack of accurate biomarkers for diagnosis and prognosis in advanced liver diseases. Either the occurrence of first decompensation, or diagnosis of acute on chronic liver failure, severe alcoholic hepatitis, or hepatocellular carcinoma (HCC), none of the available biomarkers are satisfactory. Metabolomics is the newest of omics, being much closer than the others to the actual phenotype and pathologic changes that characterizes a certain condition. It deals with a much wider spectrum of low molecular weight bio-compounds providing a powerful platform for discovering novel biomarkers and biochemical pathways to improve diagnostic, prognostication and therapy. Until now metabolomics was applied in a wide spectrum of liver conditions, but the findings were contradictory. This review proposes a synthesis of the existing evidences of metabolomics use in advanced chronic liver diseases, decompensated liver cirrhosis, severe alcoholic hepatitis and HCC. PMID- 29599899 TI - Reactivation of hepatitis B after liver transplantation: Current knowledge, molecular mechanisms and implications in management. AB - Chronic hepatitis B (CHB) is a major global health problem affecting an estimated 350 million people with more than 786000 individuals dying annually due to complications, such as cirrhosis, liver failure and hepatocellular carcinoma (HCC). Liver transplantation (LT) is considered gold standard for treatment of hepatitis B virus (HBV)-related liver failure and HCC. However, post-transplant viral reactivation can be detrimental to allograft function, leading to poor survival. Prophylaxis with high-dose hepatitis B immunoglobulin (HBIG) and anti viral drugs have achieved remarkable progress in LT by suppressing viral replication and improving long-term survival. The combination of lamivudine (LAM) plus HBIG has been for many years the most widely used. However, life-long HBIG use is both cumbersome and costly, whereas long-term use of LAM results in resistant virus. Recently, in an effort to develop HBIG-free protocols, high potency nucleos(t)ide analogues, such as Entecavir or Tenofovir, have been tried either as monotherapy or in combination with low-dose HBIG with excellent results. Current focus is on novel antiviral targets, especially for covalently closed circular DNA (cccDNA), in an effort to eradicate HBV infection instead of viral suppression. However, there are several other molecular mechanisms through which HBV may reactivate and need equal attention. The purpose of this review is to address post-LT HBV reactivation, its risk factors, underlying molecular mechanisms, and recent advancements and future of anti-viral therapy. PMID- 29599901 TI - Management of restless legs syndrome in chronic liver disease: A challenge for the correct diagnosis and therapy. AB - AIM: To investigate the association between restless legs syndrome (RLS) and well defined chronic liver disease, and the possible therapeutic options. METHODS: Two hundred and eleven patients with chronic liver disease, complaining of sleep disturbances, painful leg sensation and daily sleepiness, were included. Patients with persistent alcohol intake, recent worsening of clinical conditions, or hepatitis C virus were excluded. Diagnosis of RLS was suggested by the Johns Hopkins questionnaire and verified by fulfilling the diagnostic criteria by Allen. All patients were tested, both at baseline and during follow-up, with the Hamilton rating scale for depression, sleep quality assessment (PSQI), Epworth sleepiness scale (ESS), International Restless Legs Syndrome Study Group evaluation, and international RLS severity (IRLS) scoring system. Iron-free level, ferritin, folate, vitamin B12 and D-OH25 were detected. Neurological examinations and blood test occurred at the beginning of the therapy, after 2 wk, and at the 28th, 75th, 105th, 135th, 165th and 205th day. Regarding therapy, pramipexole or gabapentin were used. RESULTS: Patients were moderately depressed, with evident nocturnal sleep problems and concomitant daily sleepiness. Sleep problems and involuntary leg movements had been underestimated, and RLS syndrome had not been considered before the neurological visit. All (211/211) patients fulfilled the RLS diagnostic criteria. Twenty-two patients considered their symptoms as mild, according to IRSL, but 189 found them moderate to very severe. No correlation was found between ammonium level and ESS or PSQI. Augmentation was rather precocious in our patients (135th day), and more frequent (35%) than previous data (8.3%-9.1%). The dosage of dopamine agonists was found to be associated with augmentation and appears in range with the literature. Previous intake of alcohol and lower levels of vitamins have been related to the phenomenon in our study. CONCLUSION: RLS is a common disorder, requiring rapid diagnosis and treatment. Further research is therefore fundamental. PMID- 29599902 TI - Clostridium paraputrificum septicemia and liver abscess. AB - We report the first case of a healthy 23-year-old female who underwent an interventional radiology-guided embolization of a hepatic adenoma, which resulted in a gas forming hepatic liver abscess and septicemia by Clostridium paraputrificum. A retrospective review of Clostridial liver abscesses was performed using a PubMed literature search, and we found 57 clostridial hepatic abscess cases. The two most commonly reported clostridial species are C. perfringens and C. septicum (64.9% and 17.5% respectively). C. perfringens cases carried a mortality of 67.6% with median survival of 11 h, and 70.2% of the C. perfringens cases experienced hemolysis. All C. septicum cases were found to have underlying liver malignancy at the time of the presentation with a mortality of only 30%. The remaining cases were caused by various Clostridium species, and this cohort's clinical course was significantly milder when compared to the above C. perfringens and C. septicum cohorts. PMID- 29599903 TI - Liver failure caused by prolonged state of malnutrition following bariatric surgery. AB - Bariatric surgery is an effective tool in the treatment of patients with morbid obesity. In these case reports we describe 2 patients who developed liver failure after currently-practiced types of bariatric surgery, caused by a prolonged state of malnutrition provoked by psychiatric problems. Despite intensive guidance of a psychologist and dieticians after surgery, our patients deteriorated psychologically, resulting in a prolonged state of severe malnutrition and anorexia. Finally, a state of starvation was reached, passing a critical level of the liver capacity. Patients who present with signs of severe protein malnutrition after bariatric surgery should be closely monitored and checked for nutritional status. Specific attention should be given to patients who develop psychiatric problems post-bariatric surgery. If refeeding does not result in clinical improvement, reversal surgery should be considered in a timely manner. PMID- 29599904 TI - Targeting multidrug-resistant ovarian cancer through estrogen receptor alpha dependent ATP depletion caused by hyperactivation of the unfolded protein response. AB - Ovarian cancers often recur and tumors acquire resistance to chemotherapy due to overexpression of the ATP-dependent efflux pump, multidrug resistance protein 1 (MDR1/P-glycoprotein/ABCB1). Nontoxic small molecule inhibitors targeting MDR1 have remained largely elusive. Instead, in a novel application of our recently described estrogen receptor alpha (ERalpha) biomodulator, BHPI, we targeted MDR1's substrate, ATP. BHPI depletes intracellular ATP and nearly blocks MDR1 mediated drug efflux in ovarian cancer cells by inducing toxic hyperactivation of the endoplasmic reticulum stress sensor, the unfolded protein response (UPR). BHPI increased sensitivity of MDR1 overexpressing multidrug resistant OVCAR-3 ovarian cancer cells to killing by paclitaxel by >1,000 fold. BHPI also restored doxorubicin sensitivity in OVCAR-3 cells and in MDR1 overexpressing breast cancer cells. In an orthotopic OVCAR-3 xenograft model, paclitaxel was ineffective and the paclitaxel-treated group was uniquely prone to form large secondary tumors in adjacent tissue. BHPI alone strongly reduced tumor growth. Notably, tumors were undetectable in mice treated with BHPI plus paclitaxel. Compared to control ovarian tumors, after the combination therapy, levels of the plasma ovarian cancer biomarker CA125 were at least several hundred folds lower; moreover, CA125 levels progressively declined to undetectable. Targeting MDR1 through UPR dependent ATP depletion represents a promising therapeutic strategy.

AB - Aim: Endometriosis-related ovarian neoplasms (ERONs) have recently attracted considerable attention; however, the prevalence and patterns of ARID1A and POLE mutations in ERONs have not been studied in detail. The aim of this study was to investigate not only the carcinogenesis of ERONs, but also the prognostic significance of several gene mutations in this cohort. We used DNA purified from only tumor epithelial cells, from which fibroblasts were removed, using a specific method we called "liquid microdissection". Methods: Tissue samples from 22 ovarian carcinomas (13 endometrioid, and nine clear cell) were used. Tumor cells were isolated using a cell sorting system and DNA was purified from tumor epithelial cells. Nucleotide sequencing was conducted to analyze the mutational status of ARID1A, p53, PTEN, POLE, PIK3CA, and KRAS. Results: In ERONs, the frequencies of somatic mutations in ARID1A, p53, POLE, PTEN, PIK3CA, and KRAS were 19/20 (95.0%), 7/19 (36.8%), 9/22 (40.9%), 13/19 (68.4%), 3/19 (15.8%), and 1/9 (11.1%). The frequency of ARID1A mutations was significantly higher than that reported previously. Kaplan-Meier survival analysis revealed that mutations in all genes, including POLE, were not associated with patient prognosis in our Japanese cohort. Conclusions: Our results suggest that the frequency of ARID1A mutations in ERONs may be higher than that previously reported. In addition, the "liquid microdissection" method that we chose for DNA purification could be used to obtain high-quality sequencing results. The findings suggest that ARID1A mutations represent the basis of ERON carcinogenesis; other subsequent gene mutations may result in the progression of carcinogenesis. PMID- 29599906 TI - Dynamic changes during the treatment of pancreatic cancer. AB - This manuscript follows a single patient with pancreatic adenocarcinoma for a five year period, detailing the clinical record, pathology, the dynamic evolution of molecular and cellular alterations as well as the responses to treatments with chemotherapies, targeted therapies and immunotherapies. DNA and RNA samples from biopsies and blood identified a dynamic set of changes in allelic imbalances and copy number variations in response to therapies. Organoid cultures established from biopsies over time were employed for extensive drug testing to determine if this approach was feasible for treatments. When an unusual drug response was detected, an extensive RNA sequencing analysis was employed to establish novel mechanisms of action of this drug. Organoid cell cultures were employed to identify possible antigens associated with the tumor and the patient's T-cells were expanded against one of these antigens. Similar and identical T-cell receptor sequences were observed in the initial biopsy and the expanded T-cell population. Immunotherapy treatment failed to shrink the tumor, which had undergone an epithelial to mesenchymal transition prior to therapy. A warm autopsy of the metastatic lung tumor permitted an extensive analysis of tumor heterogeneity over five years of treatment and surgery. This detailed analysis of the clinical descriptions, imaging, pathology, molecular and cellular evolution of the tumors, treatments, and responses to chemotherapy, targeted therapies, and immunotherapies, as well as attempts at the development of personalized medical treatments for a single patient should provide a valuable guide to future directions in cancer treatment. PMID- 29599907 TI - Epidrug-induced upregulation of functional somatostatin type 2 receptors in human pancreatic neuroendocrine tumor cells. AB - Somatostatin receptors are a pivotal target for treatment of pancreatic neuroendocrine tumors (pNET), either with somatostatin analogues (SSA) or radiolabeled SSA. The highest affinity target for the most commonly used SSA is the somatostatin receptor type 2 (sst2 ). An important factor that may complicate treatment efficacy, is the variable number of receptors expressed on pNETs. Gene expression is subject to complex regulation, in which epigenetics has a central role. In this study we explored the possible role of epigenetic modifications in the variations in sst2 expression levels in two human pNET cell lines, BON-1 and QGP-1. We found upregulation of sst2 mRNA after treatment with the epidrugs 5-aza 2'-deoxycytidine (5-aza-dC) and valproic acid (VPA), an increased uptake of radiolabeled octreotide, as well as increased sensitivity to the SSA octreotide in functional cAMP inhibition. At epigenetic level we observed low methylation levels of the sst2 gene promoter region irrespective of expression. Activating histone mark H3K9Ac can be regulated with epidrug treatment, with an angle of effect corresponding to the effect on mRNA expression. Repressive histone mark H3K27me3 is not regulated by either 5-aza-dC or VPA. We conclude that epidrug treatment, in particular with combined 5-aza-dC and VPA treatment, might hold promise for improving and adding to current SSA treatment strategies of patients with pNETs. PMID- 29599908 TI - Regulatory B cells induced by pancreatic cancer cell-derived interleukin-18 promote immune tolerance via the PD-1/PD-L1 pathway. AB - Dysregulation of regulatory B cells (Bregs), a type of immunosuppressive lymphocyte, are associated with development of autoimmune diseases and cancers. Bregs produce immune tolerance-inducing cell surface molecules and tolerogenic cytokines (interleukin [IL]-10 and transforming growth factor-beta). We previously showed that levels of the inflammatory cytokine IL-18 were increased in patients with pancreatic cancer. In the present study study, we found that pancreatic cancer cell-derived IL-18 increases Breg-induced immunosuppression. IL 18 also promoted B-cell proliferation and IL-10 expression in vivo and in vitro. In addition, IL-18 upregulated membrane PD-1 in B cells and inhibited the antibody-dependent cellular cytotoxicity of Tc cells and natural killer cells. Finally, the combination of a natural IL-18 inhibitor (IL-18BP) and a PD-1/PD-L1 inhibitor suppressed tumor growth and metastasis in a murine pancreatic cancer model. Our results show that IL-18 and PD-1/PD-L1 could be therapeutic targets in pancreatic cancer. PMID- 29599909 TI - RNA-binding protein AUF1 suppresses miR-122 biogenesis by down-regulating Dicer1 in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is one of the common cancers worldwide, especially in developing countries. Although the chronic infections of hepatitis B and C viruses have been established as the etiological factors of HCC, the mechanism for the tumorigenesis and development of HCC is still unclear. The liver-specific microRNA-122 (miR-122), an established tumor-suppressor miRNA, is often down regulated in HCC, while the underlying mechanism is not well understood. Here we report that the AU-rich element-binding factor AUF1 suppresses the expression of Dicer1, the type III RNase that is required for microRNA maturation, leading to the inhibited biogenesis of miR-122. Overexpression of AUF1 led to the decreased expression of Dicer1 and miR-122, while the level of the miR-122 precursor (pre miR-122) was increased. On the other hand, siRNA of AUF1 (siAUF1) increased the levels of Dicer1 mRNA and miR-122, but it reduced the abundance of pre-miR-122. Consistent with the reported data, this study demonstrated that AUF1 and Dicer1 showed opposite expression pattern in both human HCC tissues and cell lines. In addition, AUF1 inhibited the expression of Dicer1 by interacting with the 3' untranslated region (3'UTR) and coding region of DICER1 mRNA. Moreover, the knockdown of AUF1 by siRNA altered the expression of other miRNAs and promoted HCC cell death. In conclusion, AUF1 down-regulates the expression miR-122 by interacting with the 3'UTR and coding region of DICER1 mRNA and suppressing Dicer1 expression. The AUF1/Dicer1/miR-122 pathway might play a critical role in the development of HCC. PMID- 29599910 TI - Developing a genetic signature to predict drug response in ovarian cancer. AB - There is a lack of personalized treatment options for women with recurrent platinum-resistant ovarian cancer. Outside of bevacizumab and a group of poly ADP ribose polymerase inhibitors, few options are available to women that relapse. We propose that efficacious drug combinations can be determined via molecular characterization of ovarian tumors along with pre-established pharmacogenomic profiles of repurposed compounds. To that end, we selectively performed multiple two-drug combination treatments in ovarian cancer cell lines that included reactive oxygen species inducers and HSP90 inhibitors. This allowed us to select cell lines that exhibit disparate phenotypes of proliferative inhibition to a specific drug combination of auranofin and AUY922. We profiled altered mechanistic responses from these agents in both reactive oxygen species and HSP90 pathways, as well as investigated PRKCI and lncRNA expression in ovarian cancer cell line models. Generation of dual multi-gene panels implicated in resistance or sensitivity to this drug combination was produced using RNA sequencing data and the validity of the resistant signature was examined using high-density RT qPCR. Finally, data mining for the prevalence of these signatures in a large scale clinical study alluded to the prevalence of resistant genes in ovarian tumor biology. Our results demonstrate that high-throughput viability screens paired with reliable in silico data can promote the discovery of effective, personalized therapeutic options for a currently untreatable disease. PMID- 29599911 TI - Effects of carbon ion beam alone or in combination with cisplatin on malignant mesothelioma cells in vitro. AB - Malignant mesothelioma (MM) is extremely aggressive and a typical refractory cancer. In this study we investigated how effective on killing MM cells by carbon ion beam alone or in combination with cisplatin (CDDP) in vitro. Carbon ion beam (at the center of SOBP with 50 keV/um of average LET) dose-independently suppressed MM cells MESO-1 and H226 cell viability and in combination with CDDP (25 MUM) significantly enhanced its action. Relative biological effectiveness (RBE) values at 73 keV/MUm and 13 keV/MUm portion of carbon ion beam was estimated as 2.82-2.93 and 1.19-1.22 at D10 level relative to X-ray, respectively by using colony formation assay. Quantitative real time PCR analysis showed that expression of apoptosis-related BAX and autophagy-related Beclin1 and ATG7 was significantly enhanced by carbon ion beam alone or in combination with CDDP. Apoptosis analysis showed that caspase 3/7 activity and the percentage of apoptotic cells was dose-dependently increased after carbon ion beam and it was further increased when combined with CDDP. Spheroid formation ability of cancer stem like CD44+/CD26+ cells was significantly inhibited by carbon ion beam combined with CDDP. Besides, carbon ion beam combined with cisplatin significantly inhibited cell cycle progression (sub-G1 arrest) and induced more large number of gammaH2AX foci. In conclusion, carbon ion beam combined with CDDP has superior potential to kill MM cells including CSCs with enhanced apoptosis. PMID- 29599912 TI - Coagulation cascade and complement system in systemic lupus erythematosus. AB - This study was conducted to (1) characterize coagulation cascade and complement system in systemic lupus erythematosus (SLE); (2) evaluate the associations between coagulation cascade, complement system, inflammatory response and SLE disease severity; (3) test the diagnostic value of a combination of D-dimer and C4 for lupus activity. Transcriptomics, proteomics and metabolomics were performed in 24 SLE patients and 24 healthy controls. The levels of ten coagulations, seven complements and three cytokines were measured in 112 SLE patients. Clinical data were collected from 2025 SLE patients. The analysis of multi-omics data revealed the common links for the components of coagulation cascade and complement system. The results of ELISA showed coagulation cascade and complement system had an interaction effect on SLE disease severity, this effect was pronounced among patients with excess inflammation. The analysis of clinical data revealed a combination of D-dimer and C4 provided good diagnostic performance for lupus activity. This study suggested that coagulation cascade and complement system become 'partners in crime', contributing to SLE disease severity and identified the diagnostic value of D-dimer combined with C4for lupus activity. PMID- 29599913 TI - Time-dependent effects of late-onset dietary intake of salidroside on lifespan and age-related biomarkers of the annual fish Nothobranchius guentheri. AB - One of the most studied and widely accepted conjectures of aging process is the oxidative stress theory. Previous studies have shown that salidroside can protect D-galactose-induced mouse model against aging and a formulation of Rhodiola rosea extracts (SHR-5) containing salidroside increases lifespan of fruit fly. However, direct evidence linking salidroside itself with the observed anti-aging effect in vivo and relevant molecular mechanisms are poorly defined. In this study, we first demonstrated that salidroside exhibited a time-dependent effect, and late onset long-term salidroside dietary intake extended the lifespan in the annual fish Nothobranchius guentheri. We then showed that salidroside reduced the accumulation of lipofuscin in the gills as well as the levels of protein oxidation, lipid peroxidation and reactive oxygen species in the muscles; enhanced the activities of catalase, glutathione peroxidase, and superoxide dismutase in the fish; and decelerated the increase of P66shc, a critical factor for regulation of intracellular reactive oxygen species contents. Collectively, these data indicate that salidroside can prolong the lifespan and retard the onset of age-related biomarkers via the antioxidant system in aging fish. It also suggests that salidroside may have a potential usefulness in prolonging the lifespan of the elderly. PMID- 29599914 TI - Serum microRNAs as predictors of risk for non-muscle invasive bladder cancer. AB - MicroRNAs (miRNAs) are implicated in the development of nearly all cancers and may function as promising biomarkers for early detection, diagnosis and prognosis. We sought to investigate the role of serum miRNAs as potential diagnostic biomarkers or biomarkers of risk for early-stage bladder cancer. First, we profiled global serum miRNAs in a pilot set of 10 non-muscle invasive bladder cancer (NMIBC) cases and 10 healthy controls matched on age, gender and smoking status. Eighty nine stably detectable miRNAs were selected for further testing and quantification by high-throughput Taqman analysis using the Fluidigm BioMark HD System to assess their association with NMIBC risk in both discovery and validation sets totaling 280 cases and 278 controls. We found miR-409-3p and six miRNAs expression ratios were significantly associated with risk of bladder cancer in both discovery and validation sets. Interestingly, we identified expression of miR-409-3p and miR-342-3p inversely correlated with age and age of onset of NMIBC. A risk score was generated based on the combination of three miRNA ratios (miR-29a-3p/miR-222-3p, miR-150-5p/miR-331-3p, miR-409-3p/miR-423 5p). In dichotomized analysis, we found individuals with high risk score showed increased risk of bladder cancer in the discovery, validation, and combined sets. Pathway enrichment analyses suggested altered miRNAs and cognate target genes are linked to the retinoid acid receptor (RAR) signaling pathway. Overall, these results suggested specific serum miRNA signatures may serve as noninvasive predictors of NMIBC risk. Biological insights underlying bladder cancer development based on the pathway enrichment analysis may reveal novel therapeutic targets for personalized medicine. PMID- 29599915 TI - Pertuzumab, trastuzumab and eribulin mesylate therapy for previously treated advanced HER2-positive breast cancer: a feasibility study with analysis of biomarkers. AB - The standard treatment for advanced human epidermal growth factor receptor 2 (HER2)-positive breast cancer is the triple combination of pertuzumab, trastuzumab and docetaxel, but some patients cannot tolerate taxane. To explore a non-taxane triple therapy, we conducted a feasibility study of pertuzumab, trastuzumab and eribulin mesylate (PTE) therapy for previously treated advanced HER2-positive breast cancer with analyses of quality of life and biomarkers. Ten patients were enrolled, two of whom had a history of docetaxel allergy. The median number of prior regimens was 3. The most common Grade 3 toxicities were leukopenia (70%) and neutropenia (70%). Grade 4 or 5 adverse events were not observed. An improving trend for the Functional Assessment of Cancer Therapy Breast (FACT-B) score at 3 months was observed. Eight cases were included in the biomarker analysis. The peripheral CD8+ T cell/ CD4+Foxp3+ regulatory T cells (Tregs) ratio was significantly increased (p = 0.039). The frequency of peripheral Tregs was associated with the trastuzumab trough concentration (p = 0.019). In a non-clinical analysis, Eribulin mesylate significantly inhibited Ser473 Akt phosphorylation in PIK3CA wild-type cells and mutated cells. These results suggest that PTE therapy is a feasible and promising option for advanced HER2-positive breast cancer. Further investigation is warranted. PMID- 29599916 TI - PD-L1 expression and presence of TILs in small intestinal neuroendocrine tumours. AB - Background: The extent of resistance to immune surveillance in patients with well differentiated (Wd) (grade 1/2) small-intestinal neuroendocrine tumours (Si-NETs) is unknown. Methods: Patients diagnosed with Wd Si-NETs (excluding appendix, which are considered to have a different biology to other midgut NETs) were eligible. Tumoural programmed death (PD)-ligand(L) 1 (PD-L1)/PD-L2/PD-1 and tumour infiltrating lymphocytes (TILs) [presence and phenotype] were analysed in archival tissue by immunohistochemistry (IHC); reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used for confirmation of IHC results. Results: Of 109 patients screened, 62 were eligible: 54.8% were male; median age was 63.7 years (95%-CI 59.7-67.2); disease stage II: 4.8%, III: 40.3% and IV: 54.8%; 41.9% were functional. Analysed samples (67.1% from primary tumours, 32.9% from metastases) were of grade 1 (67.1%) or 2 (32.86%) with a median Ki-67 of 2%. From the total of 62 eligible patients, 70 and 63 samples were suitable for IHC and RT-qPCR analysis, respectively. PD-L1 expression within tumour cells and TILs were identified in 12.8% and 24.3% of samples respectively; 30% of samples showed PD-L1 expression within tumour cells and/or TILs. PD-1 was present in TILs in 22.8% of samples. Majority of samples showed significant presence of CD4+ (focal 42.86%; moderate 2.86%) and CD8+ (focal 92.86%; moderate 4.29%) TILs. IHC findings were confirmed with RT-qPCR; which showed higher expression levels of PD L1 (p-value 0.007) and PD-1 (p-value 0.001) in samples positive for IHC compared to negative-IHC. Conclusions: Thirty-percent of patients express PD-L1 within tumour cells and/or TILs. Identification of presence of TILs was also significant and warrant the investigation of immunotherapy in this setting. PMID- 29599917 TI - PGE2 mediates EGFR internalization and nuclear translocation via caveolin endocytosis promoting its transcriptional activity and proliferation in human NSCLC cells. AB - Prostaglandin E2 (PGE2) contributes to tumor progression by promoting cancer cell growth, invasion and by creating a favorable pro-tumor microenvironment. PGE2 has been reported to transactivate and internalize into the nucleus receptor tyrosine kinases such as Epidermal growth factor receptor (EGFR), thereby supporting tumor progression. Here we demonstrate that in non-small cell lung carcinoma (NSCLC) cells, PGE2 induces EGFR nuclear translocation via different dynamin-dependent endocytic pathways, promotes the formation of an EGFR-STAT3 complex, affects nuclear EGFR target gene expression and mediates tumor cell proliferation. Indeed, we find that PGE2 induces EGFR internalization and consequent nuclear import through Clathrin- and Caveolin-mediated endocytosis and through the interaction of EGFR with Importin beta1. Within the nucleus, EGFR forms a complex with STAT3, an event blocked by ablation of Clathrin Heavy Chain or Caveolin-1. The combination of EGF and PGE2 prolongs nuclear EGFR transcriptional activity manifested by the upregulation of CCND1, PTGS2, MYC and NOS2 mRNA levels and potentiates nuclear EGFR-induced NSCLC cell proliferation. Additionally, NSCLC patients with high expression of a nuclear EGFR gene signature display shorter survival times than those with low expression, thus showing a putative correlation between nuclear EGFR and poor prognosis in NSCLC. Together, our findings indicate a complex mechanism underlying PGE2-induced EGF/EGFR signaling and transcriptional control, which plays a key role in cancer progression. PMID- 29599918 TI - FC-99 ameliorates sepsis-induced liver dysfunction by modulating monocyte/macrophage differentiation via Let-7a related monocytes apoptosis. AB - Background: The liver is a vital target for sepsis-related injury, leading to inflammatory pathogenesis, multiple organ dysfunction and high mortality rates. Monocyte-derived macrophage transformations are key events in hepatic inflammation. N1-[(4-methoxy)methyl]-4-methyl-1,2-benzenediamine (FC-99) previously displayed therapeutic potential on experimental sepsis. However, the underlying mechanism of this protective effect is still not clear. Results: FC-99 treatment attenuated the liver dysfunction in septic mice that was accompanied with reduced numbers of pro-inflammatory Ly6Chi monocytes in the peripheral blood and CD11b+F4/80lo monocyte-derived macrophages in the liver. These effects were attributed to the FC-99-induced apoptosis of CD11b+ cells. In PMA-differentiated THP-1 cells, FC-99 repressed the expression of CD11b, CD14 and caspase3 and resulted in a high proportion of Annexin V+ cells. Moreover, let-7a-5p expression was abrogated upon CLP stimulation in vivo, whereas it was restored by FC-99 treatment. TargetScan analysis and luciferase assays indicated that the anti apoptotic protein BCL-XL was targeted by let-7a-5p. BCL-XL was inhibited by FC-99 in order to induce monocyte apoptosis, leading to the impaired monocyte-to macrophage differentiation. Materials and Methods: Murine acute liver failure was generated by caecal ligation puncture surgery after FC-99 administration; Blood samples and liver tissues were collected to determine the monocyte/macrophage subsets and the induction of apoptosis. Human acute monocytic leukemia cell line (THP-1) cells were pretreated with FC-99 followed by phorbol-12-myristate-13 acetate (PMA) stimulation, in order to induce monocyte-to-macrophage differentiation. The target of FC-99 and the mechanistic analyses were conducted by microarrays, qRT-PCR validation, TargetScan algorithms and a luciferase report assay. Conclusions: FC-99 exhibits potential therapeutic effects on CLP-induced liver dysfunction by restoring let-7a-5p levels. PMID- 29599919 TI - Trib2 expression in granulocyte-monocyte progenitors drives a highly drug resistant acute myeloid leukaemia linked to elevated Bcl2. AB - Trib2 pseudokinase has oncogenic and tumour suppressive functions depending on the cellular context. We investigated the ability of Trib2 to transform different haemopoietic stem and progenitor cells (HSPCs). Our study identified the granulocyte-macrophage progenitor (GMP) subpopulation as a potent leukaemia initiating cell of Trib2-driven AML in vivo. Trib2 transformed GMPs generated a fully penetrant and short latency AML. AML cells expressing elevated Trib2 led to a chemoresistant phenotype following chemotherapy treatment. We show that Trib2 overexpression results in an increase in BCL2 expression, and high Trib2 expressing cells are highly sensitive to cell killing by BCL2 inhibition (ABT199). Combined treatment with chemotherapeutic agents and BCL2 inhibition resulted in synergistic killing of Trib2+ AML cells. Trib2 transformed GMP AML cells showed more chemoresistance compared with HSPC derived Trib2 AML cells associated with higher Bcl2 expression. There is significant correlation of high TRIB2 and BCL2 expression in patient derived human AML cells. These data demonstrate that the cell of origin influences the leukaemic profile and chemotherapeutic response of Trib2+ AML. Combined TRIB2 and BCL2 expression in AML cells may have clinical utility relevant for monitoring drug resistance and disease relapse. PMID- 29599920 TI - Molecular dissection of engraftment in a xenograft model of myelodysplastic syndromes. AB - Myelodysplastic syndromes (MDS) are oligoclonal disorders of the hematopoietic stem cells (HSC). Recurrent gene mutations are involved in the MDS physiopathology along with the medullar microenvironment. To better study the heterogeneity of MDS, it is necessary to create patient derived xenograft (PDX). We have reproduced a PDX model by xenografting HSC (CD34+) and mesenchymal stromal cells (MSC) in NOD/SCID/IL2rgamma-/- mice with primary samples from one RAEB2, two RAEB1 and one RARS patients harboring karyotype abnormalities and gene mutations. The average human chimerisms ranged from 59.7% to 0.0175% for the 4 patients. Secondary grafts (G2) were only performed for mice derived from the RAEB2 patient and the average human chimerism was 53.33%. G1 mice 1 and 2, and their derived G2 mice showed less than 20% of medullar blasts whereas mouse 3 and the resulting G2 mice transformed to AML. Clonal architecture was dissected in the different hematopoietic progenitors (HP) harvested from G1 and G2 mice. By direct Sanger sequencing, we found the 4 initial mutations in each HP subpopulation and those mutations had the same variant allele frequency in the CD34+ CD38- HSC from G1 and G2 mice by next generation sequencing (NGS). Targeted NGS analysis done in HSC of mouse 3 did not show any additional driver gene mutations explaining the transformation to AML. To conclude, we have generated a PDX mouse model that perfectly reproduces the MDS founder clone which is stable over time, allowing us to consider this system as a powerful tool to test therapeutic approaches. PMID- 29599921 TI - A multicenter round robin test of PD-L1 expression assessment in urothelial bladder cancer by immunohistochemistry and RT-qPCR with emphasis on prognosis prediction after radical cystectomy. AB - Background: Immunohistochemical PD-L1 assessment is currently used to identify responders towards checkpoint inhibitors although it is limited by inter-observer effects. Here, we conducted a multi-center round robin test to prove the possibility of assessing the PD-L1 status by gene expression to avoid inter observer effects. Patients and methods: Gene expression of PD-L1 was analyzed in a total of 294 samples (14 cases non-muscle invasive and muscle-invasive bladder cancer; MIBC) in seven centers by a RT-qPCR kit and compared with immunohistochemical scoring of three pathologists (DAKO, 22c3). Both assays were compared towards prognosis prediction in a cohort of 88 patients with MIBC. Results: PD-L1 gene expression revealed very high inter center correlation (centrally extracted RNA: r = 0.68-0.98, p <= 0.0076; locally extracted RNA: r = 0.81-0.98, p <= 0.0014). IHC Inter-observer concordance was moderate to substantial for immune cells (IC), fair for combined IC/ tumor cell (TC) (IC: kappa = 0.50-0.61; IC + TC: kappa = 0.50), and fair for TC scoring (kappa = 0.26 0.35). Gene expression assessment resulted in more positive cases (9/14 cases positive vs. 6/14 cases [IHC]) which could be validated in the independent cohort. Positive mRNA status was associated with significantly better overall and disease-specific survival (5-year OS: 50% vs. 26%, p = 0.0042, HR = 0.48; 5 year DSS: 65% vs. 40%, p = 0.012, HR = 0.49). The 1% IHC IC cut-off also revealed significant better OS (5 year OS: 58% vs. 31%, p = 0.036, HR = 0.62). Conclusion: Gene expression showed very high inter-center agreement. Gene expression assessment also resulted in more positive cases and revealed better prognosis prediction. PD-L1 mRNA expression seems to be a reproducible and robust tool for PD-L1 assessment. PMID- 29599922 TI - Modularity of the metabolic gene network as a prognostic biomarker for hepatocellular carcinoma. AB - Abnormal metabolism is an emerging hallmark of cancer. Cancer cells utilize both aerobic glycolysis and oxidative phosphorylation (OXPHOS) for energy production and biomass synthesis. Understanding the metabolic reprogramming in cancer can help design therapies to target metabolism and thereby to improve prognosis. We have previously argued that more malignant tumors are usually characterized by a more modular expression pattern of cancer-associated genes. In this work, we analyzed the expression patterns of metabolism genes in terms of modularity for 371 hepatocellular carcinoma (HCC) samples from the Cancer Genome Atlas (TCGA). We found that higher modularity significantly correlated with glycolytic phenotype, later tumor stages, higher metastatic potential, and cancer recurrence, all of which contributed to poorer prognosis. Among patients with recurred tumors, we found the correlation of higher modularity with worse prognosis during early to mid-progression. Furthermore, we developed metrics to calculate individual modularity, which was shown to be predictive of cancer recurrence and patients' survival and therefore may serve as a prognostic biomarker. Our overall conclusion is that more aggressive HCC tumors, as judged by decreased host survival probability, had more modular expression patterns of metabolic genes. These results may be used to identify cancer driver genes and for drug design. PMID- 29599923 TI - Umbilical cord blood mononuclear cell therapy induces clinical remission of steroid-dependent or -resistant ulcerative colitis patients. AB - To compare the efficacy and safety of umbilical cord blood mononuclear cells (CBMNC) and azathioprine (AZA) in the treatment of patients with steroid dependent or -resistant ulcerative colitis. One hundred and six patients diagnosed with steroid-dependent or -resistant ulcerative colitis were studied retrospectively, including 36 patients treated with CBMNC and 70 treated with AZA. To reduce confounding bias due to retrospective nature of this study, the propensity score matching system was applied to equipoise the pretreatment data of two groups. After matching, 35 matched pairs (1:1) were created. The ratios of clinical remission, clinical response and endoscopic mucosal healing, Mayo score, and major complications were compared between two groups at weeks 8, 16, and 36 after treatment. The results demonstrated that the ratios of clinical remission (80% vs. 57%, P < 0.05) and mucosal healing (74% vs. 51%, P < 0.05) were significantly higher in CBMNC-treated patients compared with those in AZA-treated patients at week 8. The erythrocyte sedimentation rate was significantly decreased in CBMNC group compared with that in AZA-treated group (14.5 +/- 3.9 mm/h vs. 18.0 +/- 5.7 mm/h, P < 0.01) at week 8. In AZA group, 2 patients had neutropenia and 3 patients had elevated alanine aminotransferase levels, whereas no obvious side-effects were observed in CBMNC-treated group. Our results reveal that CBMNC therapy appears to be an effective and safe strategy for patients with steroid-dependent or -resistant ulcerative colitis. Further prospective studies are needed to define the potential roles and mechanisms of CBMNC in the treatment of refractory ulcerative colitis. PMID- 29599924 TI - Asiatic acid attenuates lipopolysaccharide-induced injury by suppressing activation of the Notch signaling pathway. AB - Sepsis is a severe multisystem disease with high mortality rates and limited treatment options. However, advances during the last decade have opened opportunities to develop novel therapeutic strategies. The Notch signaling pathway plays a critical role in inflammation, and its inhibition offers an avenue to treat inflammatory diseases, such as sepsis. Asiatic acid (AA), a triterpenoid isolated from Centella asiatica, reportedly exerts anti-oxidant, anti-tumor, and anti-inflammatory effects, but its mechanisms remain unclear. In our study, we found that AA decreased levels of interleukin-1beta (IL-1beta), IL 6, alanine aminotransferase and blood urea nitrogen in serum; attenuated liver, lung and kidney damage; and improved the survival among mice with experimental sepsis. AA also reduced lipopolysaccharide-stimulated expression of proinflammatory mediators, including nitric oxide, IL-1beta and IL-6 in RAW 264.7 macrophages. Notably, we demonstrated for the first time that AA is a novel small molecule inhibitor of the Notch signaling pathway. Its effects include upregulation of Notch receptor (Notch3) and delta-like ligand (DLL4), inhibition of Notch3 binding to the IL-6 promoter and regulation of mitochondrial function. These novel effects of AA may provide new approaches and strategies for the treatment of inflammatory disorders.

AB - Nonalcoholic fatty liver disease (NAFLD) is caused by ectopic fat accumulation in the liver. NAFLD is associated with hepatic inflammation and oxidative stress, resulting in nonalcoholic steatohepatitis (NASH) with advanced fibrosis. Placental extracts have been used to treat various chronic diseases due to their antioxidative effect. However, the effects of the extracts on the development of NASH have yet to be elucidated. Here, we demonstrated that supplementation with an oral porcine placental extract (PPE) attenuated lipid accumulation and peroxidation, insulin resistance, inflammatory and stress signaling, and fibrogenesis in the liver of NASH model mice fed a high-cholesterol and high-fat diet. The PPE reduced the number of M1-like liver macrophages, but increased the number of anti-inflammatory M2-like macrophages, resulting in a predominance of M2 over M1 macrophage populations in the liver of NASH mice. Accordingly, the PPE suppressed lipopolysaccharide-induced M1 polarization in isolated murine peritoneal macrophages, whereas it facilitated interleukin 4-induced M2 polarization. Furthermore, the PPE reduced the hepatic stellate cell (HSC) activation associated with the attenuated transforming growth factor-beta/Smad3 signaling, both in the liver of NASH mice and in RI-T cells, a HSC line. The PPE may be a potential approach to prevent NASH by limiting lipid peroxidation, promoting M2 macrophage polarization, and attenuating HSC activation.

AB - Introduction: Clinical research is conducted by academia, cooperative groups (CGs) or pharmaceutical industry. Here, we evaluate the role of CGs and funding sources in the development of guidelines for breast cancer therapies. Results: We identified 94 studies. CGs were involved in 28 (30%) studies while industry either partially or fully sponsored 64 (68%) studies. The number of industry funded studies increased over time (from 0% in 1976 to 100% in 2014; p for trend = 0.048). Only 10 (11%) government or academic studies were identified. Studies conducted by GCs included a greater number of subjects (median 448 vs. 284; p = 0.015), were more common in the neo/adjuvant setting (p < 0.0001), and were more often randomized (p = 0.018) phase III (p < 0.0001) trials. Phase III trial remained significant predictor for CG-sponsored trials (OR 7.1 p = 0.004) in a multivariable analysis. Industry funding was associated with higher likelihood of positive outcomes favoring the sponsored experimental arm (p = 0.013) but this relationship was not seen for CG-sponsored trials (p = 0.53). Materials and Methods: ASCO, ESMO, and NCCN guidelines were searched to identify systemic anti cancer therapies for early-stage and metastatic breast cancer. Trial characteristics and outcomes were collected. We identified sponsors and/or the funding source(s) and determined whether CGs, industry, or government or academic institutions were involved. Chi-square tests were used for comparison between studies. Conclusions: Industry funding is present in the majority of studies providing the basis for which recommendations about treatment of breast cancer are made. Industry funding, but not CG-based funding, was associated with higher likelihood of positive outcomes in clinical studies supporting guidelines for systemic therapy. PMID- 29599927 TI - The prognostic value of CXC chemokine receptor 2 (CXCR2) in cancers: a meta analysis. AB - Background & Aims: Quite a few studies had investigated the correlation between CXC chemokine receptor 2 (CXCR2) and cancer. This meta-analysis was aimed to comprehensively summarize the previous studies and to explore the prognostic value of CXCR2 in patients with cancer. Materials and Methods: An adequate literature search in EMBASE and PubMed was conducted. Articles in English which have reported CXCR2 expression in patients and enough data to calculate hazard ratio (HR) were included. Effect estimates were analyzed with Review Manager 5.2. The endpoint was overall survival (OS) and recurrence-free survival (RFS). Result: Twelve studies from 10 publications with a total of 2,461 patients were identified. It was shown that high level of CXCR2 was significantly associated with poorer overall survival (OS) (HR = 1.69, 95% CI = 1.46-1.96, p < 0.0001, I2 = 45%) and RFS (HR = 1.50, 95% CI = 1.25-1.80, p < 0.0001, I2 = 6%). The analyses of different analysis models (univariate or multivariate models), sample size (< 300 or >= 300) and ethnicity (Asian and Caucasian) have indicated the negative impact of CXCR2 over-expression on survival of patients with cancer. Stratified by cancer type, high-expression of CXCR2 was associated with unfavorable OS in laryngeal squamous cell carcinoma, lung cancer, pancreatic ductal carcinoma, clear-cell renal cell carcinoma and hepatocellular carcinoma; however, there was significant difference between high- and low-expression of CXCR2 in digestive tract cancer (esophageal adenocarcinoma and squamous cell carcinoma procession, resected esophageal carcinoma, esophageal cancer and gastric cancer). Conclusions: CXCR2 is an unfavorable predictor in terms of OS and RFS in patients with cancer except for digestive tract cancer and is related with poorer prognostic. PMID- 29599928 TI - The association of 5HT2A and 5HTTLPR polymorphisms with Alzheimer's disease susceptibility: a meta-analysis with 6945 subjects. AB - Alzheimer's disease (AD) is a progressive neurodegenerative disease. Relationships of 5HT2A and 5HTTLPR polymorphisms and AD risk have been widely investigated previously, whereas results derived from these studies were inconclusive and controversial. The aim of this study was to investigate the association of the 5-HT2A and 5HTTLPR polymorphisms and AD using a meta-analysis of existing literatures. Studies were collected using PubMed, Web of Science, the Cochrane Library databases, Chinese National Knowledge Infrastructure (CNKI) and Embase. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess associations. As a result, a total of 7 publications for 5-HT2A T102C and 16 publications for 5HTTLPR (L/S) comprised 3255 cases and 3690 controls fulfilled the inclusion criteria. Significant association was covered between allelic and recessive models of 5-HT2A T102C and AD (allelic model: p = 0.003, OR [95% CI] = 1.23 [1.07, 1.40]; recessive model: p = 0.03, OR [95% CI] = 1.28 [1.02, 1.59]). Subsequently, we conducted subgroup analysis for 5-HT2A T102C polymorphism based on ethnicities and APOE epsilon4, and identified a significantly increased risk for the allelic and dominant models of 5-HT2A T102C and AD in Asian subgroup (allelic model: p = 0.002, OR [95% CI] = 1.42 [1.14, 1.78]; dominant model: p = 0.02, OR [95% CI] = 1.60 [1.09, 2.35]) and subgroup without APOE epsilon4 (allelic model: p = 0.02, OR [95% CI] = 1.44 [1.05, 1.99]; dominant model: p = 0.0008, OR [95% CI] = 2.49 [1.46, 4.25]). Nevertheless, the pooled analyses suggested no significant association between allelic, dominant, and recessive models of 5HTTLPR (L/S) and AD (p > 0.05). In conclusion, our meta analysis demonstrates that 5HT2A C10T, but not 5HTTLPR (L/S), might increase risk for AD. PMID- 29599929 TI - Tooth loss and cancer risk: a dose-response meta analysis of prospective cohort studies. AB - Conflicting results to identify the relationship between tooth loss and cancer risk. Therefore, a dose-response meta-analysis was performed to clarify and quantitative assessed the correlation between tooth loss and cancer risk. Up to March 2017, 25 observational epidemiological studies were included in current meta-analysis. Tooth loss was significantly associated with a higher risk of cancer. Additionally, tooth loss was associated with significantly a higher risk of esophageal cancer, gastric cancer, head and neck cancer, colorectal cancer, pancreas cancer, lung cancer, prostate cancer, bladder cancer and hematopoietic cancer. Subgroup analysis showed consistent findings. Furthermore, a significant dose-response relationship was observed between tooth loss and cancer risk. Increasing per 10 of tooth loss was associated with a 9% increment of cancer risk, 14% increment of esophageal cancer risk, 9% increment of gastric cancer risk, 31% increment of head and neck cancer risk, 4% increment of colorectal cancer risk, 7% increment of pancreas cancer risk, 19% increment of lung cancer risk, 2% increment of bladder cancer risk and 3% increment of hematopoietic cancer risk. Considering these promising results, tooth loss might be harmful for health. Large sample size, different ethnic population and different cancer type are warranted to validate this association. PMID- 29599930 TI - Does antipsychotic drug use increase the risk of long term mortality? A systematic review and meta-analysis of observational studies. AB - Antipsychotics (AP) are widely used to treat schizophrenia and other psychiatric disorders. However, the association between the AP use and mortality risk is controversial. We searched PubMed, EMBASE, MEDLINE, PsycINFO, CINAHL, the Cochrane Library and four Chinese databases from inception to June 2016. All observational cohort or case-control studies reporting data on mortality outcomes in individuals exposed to AP drugs were included. This systematic review included 68 studies involving 4,812,370 participants. Sixty-seven studies reported confounding factors, the most common being age, sex, race, concomitant medications, and comorbidities. For all-cause mortality, current users of AP and conventional antipsychotics (CAP) had higher mortality risk than did non-AP users [AP users: RR, 1.50; 95% CI, 1.12 to 1.99; CAP users: RR, 1.53; 95% CI, 1.16 to 2.04]. However, the association between the current use of atypical antipsychotics (AAP) and the mortality was of borderline significance, and there was no significant difference for past users of AP. Mortality was higher in current CAP users than in current AAP users. For cardiac death and sudden death, current AP and CAP users also had higher mortality risk than non-AP users. A subgroup analysis showed a possible increased risk in patients with Parkinson's, but not in those with dementia, Alzheimer's disease, schizophrenia, delirium or stroke. An increased risk of all-cause mortality for patients ?65 years may also exist. AP exposure is associated with an approximately 1.5-fold increased mortality risk. This increased risk may be particularly prominent in patients with Parkinson's and those over 65 years old. Further studies are required to evaluate the mortality risk for individual AP drugs and diseases. PMID- 29599931 TI - Association between the Glutathione-S-transferase T1 null genotype and esophageal cancer susceptibility: a meta-analysis involving 11,163 subjects. AB - Background: Glutathione-S-Transferase T1 (GSTT1) null genotype has been shown to be associated with the risk of esophageal cancer. However, the results remain inconsistent. Thus a comprehensive meta-analysis was conducted to assess the strength of association between GSTT1 null genotype and the risk of esophageal cancer. Materials and Methods: A literature search of PubMed, Embase, China National Knowledge Infrastructure (CNKI) and Wanfang databases up to March 31, 2017 was conducted and 30 eligible articles with 4482 cases and 6681 controls were finally recruited. The strength of correlation between GSTT1 polymorphism and the susceptibility of esophageal cancer was assessed by the crude odds ratios (ORs) with 95% confidence intervals (CIs). Subgroup analyses and sensitivity analyses were performed to further identify the association. Results: GSTT1 null genotype significantly increased the risk of esophageal cancer (OR = 1.20; 95% CI 1.04-1.40; P < 0.05). In a subgroup analysis by ethnicity, GSTT1 null genotype was correlated with a significantly increased risk of esophageal cancer among Asians (OR = 1.33; 95% CI 1.12-1.58; P < 0.05), instead of Caucasians or Africans (OR = 0.91; 95% CI 0.65-1.26; P > 0.05 for Caucasians and OR = 1.32; 95% CI 0.98 1.77; P > 0.05 for Africans). In the analysis by histological type, GSTT1 null genotype was correlated with a significantly increased risk of esophageal squamous cell carcinoma (OR = 1.34; 95% CI 1.12-1.61; P < 0.05), particularly among Asians (OR = 1.54; 95% CI 1.30-1.82; P < 0.05), but not among Caucasians or Africans (OR = 0.87; 95% CI 0.48-1.57; P > 0.05 for Caucasians and OR = 1.32; 95% CI 0.98-1.77; P > 0.05 for Africans). In addition, there is no significant correlation between GSTT1 null genotype and the risk of esophageal adenocarcinoma (OR = 0.98; 95% CI 0.71-1.35; P > 0.05). Conclusions: Our findings demonstrate that GSTT1 null genotype significantly increases esophageal cancer risk, particularly in Asians. PMID- 29599932 TI - Radial EBUS versus CT-guided needle biopsy for evaluation of solitary pulmonary nodules. AB - Objective: This study is aimed to compare the diagnostic yield, complications and influencing factors between Radial endobroncheal ultrasonography guided bronchoscopy(R-EBUS) and CT-guided needle biopsy (CT-PNB), for evaluation of solitary pulmonary nodules(SPNs). Matrials and Methods: 160 cases of consecutive patients with SPNs were enrolled and divided into R-EBUS and CT-PNB groups randomly. The diagnostic yield, complications and influencing factors between the two groups were evaluated. Results: Sensitivity of R-EBUS for malignancy was 73.7% (42/57) and for benign, was 43.5% (10/23), overall diagnostic accuracy was 65% (52/80). In CT-PNB group, overall diagnostic accuracy was 85% (68/80), sensitivity for malignancy was 87.9% (51/58), and for benign was 81.0% (17/21), respectively. Both overall diagnostic yield and incidence of complications in CT PNB group were higher than those in R-EBUS group (P = 0.006, P = 0.002). In R EBUS group, the factors affecting diagnostic yield were size (P = 0.027), the distance between SPNs and pleura (P = 0.031) and the location of the probe to lesions (P = 0.009). In CT-PNB group, the distance from the lesions to pleura was correlated with the incidence of pneumothorax (P = 0.001) and pulmonary haemorrhage (P = 0.042). The location of SPNs were adjacent to great vessels was another influencing factor for pulmonary haemorrhage (P = 0.042). Conclusions: Both R-EBUS and CT-PNB are valuable tools for diagnosis. SPNs located in medial 1/2 of lung field, or were adjacent to great vessels may be fit for R-EBUS. Those SPNs located in lateral 1/2 of lung field, near to pleura or with less vessels around may be more suitable for CT-PNB. PMID- 29599933 TI - The genes associated with early-onset Alzheimer's disease. AB - Alzheimer's disease (AD) is a progressive neurodegenerative disorder that accounts for the most cases of dementia, which is characterized by the deposition of dense plaques of amyloid beta (Abeta) plaques and neurofibrillary tangles consisting of hyperphosphorylated tau. The two main types of AD can be classified as early-onset AD (EOAD, onset < 65 years) and late-onset AD (LOAD, onset >= 65 years). Evidence from family and twin studies indicate that genetic factors are estimated to play a role in at least 80% of AD cases. The first milestone with linkage analysis revealed the mutations in APP, PSEN1, and PSEN2 genes that cause EOAD. But pathogenic mutations in these three genes can only explain a small fraction of EOAD families. The additional disease-causing genes have not yet been identified. This review provides an overview of the genetic basis of EOAD and the relationship between the functions of these risk genes and the neuropathologic features of AD. A better understanding of genetic mechanisms underlying EOAD pathogenesis and the potentially molecular mechanisms of neurodegeneration will lead to the development of effective diagnosis and treatment strategies for this devastating disease. PMID- 29599935 TI - BK virus-associated collecting duct carcinoma of the renal allograft in a kidney pancreas allograft recipient. AB - BK polyomavirus (BKV) nephropathy is a major concern in renal transplantation. Its main consequence is graft loss, which occurs in more than 50% of the cases. De novo renal cell carcinoma in renal allograft is a very rare event. Most of these tumors are papillary or clear cell carcinomas. We report herein the first case of collecting duct carcinoma of the renal allograft in a kidney-pancreas allograft adult recipient. Collecting duct carcinoma occurs long after the cure of a BKV nephropathy. At this time, BKV viremia and viruria were negative as well as the immunostaining for SV40 in the non-tumor kidney. The viral oncoprotein Tag persists only in the tumor cells. To preserve pancreas graft function, we maintained immunosuppression levels. After a 9-months follow-up, the evolution was free from clinical and radiological progression. The oncogenic role of BKV remains controversial in human cancers. However, strong experimental data have shown an association between BKV infection and urologic neoplasms. Further works might precise the exact role of polyomaviruses in renal carcinogenesis. In the meantime, clinical vigilance for early diagnostic of these tumors is mandatory after BKV nephropathy. PMID- 29599934 TI - Liquid biopsy provides new insights into gastric cancer. AB - Liquid biopsies have great promise for precision medicine as they provide information about primary and metastatic tumors via a minimally invasive method. In gastric cancer patients, a large number of blood-based biomarkers have been reported for their potential role in clinical practice for screening, early diagnosis, prognostic evaluation, recurrence monitoring and therapeutic efficiency follow-up. This current review focuses on blood liquid biopsies' role and their clinical implications in gastric cancer patients, with an emphasis on circulating tumor cells (CTCs), circulating tumor DNA (ctDNA) and circulating non coding RNAs (ncRNAs). We also provide a brief discussion of the potential and limitations of liquid biopsies use and their future use in the routine clinical care of gastric cancer. PMID- 29599936 TI - Effect of varying computed tomography acquisition and reconstruction parameters on semi-automated clot volume quantification. AB - AIM: To examine effects of computed tomography (CT) image acquisition/reconstruction parameters on clot volume quantification in vitro for research method validation purposes. METHODS: This study was performed in conformance with HIPAA and IRB Regulations (March 2015-November 2016). A ten blood clot phantom was designed and scanned on a dual-energy CT scanner (SOMATOM Force, Siemens Healthcare GmBH, Erlangen, Germany) with varying pitch, iterative reconstruction, energy level and slice thickness. A range of clot and tube sizes were used in an attempt to replicate in vivo emboli found within central and segmental branches of the pulmonary arteries in patients with pulmonary emboli. Clot volume was the measured parameter and was analyzed by a single image analyst using a semi-automated region growing algorithm implemented in the FDA-approved Siemens syngo.via image analysis platform. Mixed model analysis was performed on the data. RESULTS: On the acquisition side, the continuous factor of energy showed no statistically significant effect on absolute clot volume quantification (P = 0.9898). On the other hand, when considering the fixed factor of pitch, there were statistically significant differences in clot volume quantification (P < 0.0001). On the reconstruction side, with the continuous factor of reconstruction slice thickness no statistically significant effect on absolute clot volume quantification was demonstrated (P = 0.4500). Also on the reconstruction side, with the fixed factor of using iterative reconstructions there was also no statistically significant effect on absolute clot volume quantification (P = 0.3011). In addition, there was excellent R2 correlation between the scale-measured mass of the clots both with respect to the CT measured volumes and with respect to volumes measure by the water displacement method. CONCLUSION: Aside from varying pitch, changing CT acquisition parameters and using iterative reconstructions had no significant impact on clot volume quantification with a semi-automated region growing algorithm. PMID- 29599937 TI - A Novel Interpretation for Arterial Pulse Pressure Amplification in Health and Disease. AB - Arterial pressure waves have been described in one dimension using several approaches, such as lumped (Windkessel) or distributed (using Navier-Stokes equations) models. An alternative approach consists of modeling blood pressure waves using a Korteweg-de Vries (KdV) equation and representing pressure waves as combinations of solitons. This model captures many key features of wave propagation in the systemic network and, in particular, pulse pressure amplification (PPA), which is a mechanical biomarker of cardiovascular risk. The main objective of this work is to compare the propagation dynamics described by a KdV equation in a human-like arterial tree using acquired pressure waves. Furthermore, we analyzed the ability of our model to reproduce induced elastic changes in PPA due to different pathological conditions. To this end, numerical simulations were performed using acquired central pressure signals from different subject groups (young, adults, and hypertensive) as input and then comparing the output of the model with measured radial artery pressure waveforms. Pathological conditions were modeled as changes in arterial elasticity (E). Numerical results showed that the model was able to propagate acquired pressure waveforms and to reproduce PPA variations as a consequence of elastic changes. Calculated elasticity for each group was in accordance with the existing literature. PMID- 29599938 TI - Accurate Rapid Lifetime Determination on Time-Gated FLIM Microscopy with Optical Sectioning. AB - Time-gated fluorescence lifetime imaging microscopy (FLIM) is a powerful technique to assess the biochemistry of cells and tissues. When applied to living thick samples, it is hampered by the lack of optical sectioning and the need of acquiring many images for an accurate measurement of fluorescence lifetimes. Here, we report on the use of processing techniques to overcome these limitations, minimizing the acquisition time, while providing optical sectioning. We evaluated the application of the HiLo and the rapid lifetime determination (RLD) techniques for accurate measurement of fluorescence lifetimes with optical sectioning. HiLo provides optical sectioning by combining the high-frequency content from a standard image, obtained with uniform illumination, with the low frequency content of a second image, acquired using structured illumination. Our results show that HiLo produces optical sectioning on thick samples without degrading the accuracy of the measured lifetimes. We also show that instrument response function (IRF) deconvolution can be applied with the RLD technique on HiLo images, improving greatly the accuracy of the measured lifetimes. These results open the possibility of using the RLD technique with pulsed diode laser sources to determine accurately fluorescence lifetimes in the subnanosecond range on thick multilayer samples, providing that offline processing is allowed. PMID- 29599939 TI - The Influence of Accreditation on the Sustainability of Organizations with the Brazilian Accreditation Methodology. AB - This research evaluates the influence of the Brazilian accreditation methodology on the sustainability of the organizations. Critical factors for implementing accreditation were also examined, including measuring the relationships established between these factors in the organization sustainability. The present study was developed based on the survey methodology applied in the organizations accredited by ONA (National Accreditation Organization); 288 responses were received from the top level managers. The analysis of quantitative data of the measurement models was made with factorial analysis from principal components. The final model was evaluated from the confirmatory factorial analysis and structural equation modeling techniques. The results from the research are vital for the definition of factors that interfere in the accreditation processes, providing a better understanding for accredited organizations and for Brazilian accreditation. PMID- 29599940 TI - A New Intelligent Medical Decision Support System Based on Enhanced Hierarchical Clustering and Random Decision Forest for the Classification of Alcoholic Liver Damage, Primary Hepatoma, Liver Cirrhosis, and Cholelithiasis. AB - Diagnosis of liver disease principally depends on physician's subjective knowledge. Automatic prediction of the disease is a critical real-world medical problem. This work presents an EHC-ERF-based intelligence-integrated model purposive to predict different types of liver disease including alcoholic liver damage, primary hepatoma, liver cirrhosis, and cholelithiasis. These diseases cause many clinical complications, and their accurate assessment is the only way for providing efficient treatment facilities to patients. EHC is deployed to divide the data into a hierarchy structure that is more informative for the disease predictions carried out by ERF. The occurrence of ERF error rate was dependent on correlation and strength of each individual tree where correlation is directly proportional to forest error rate and strength is inversely proportional to the forest rate. In total, two individual and three integrated classification models are developed to achieve enhanced predictions for the liver disease types. Analysis of results showed that the proposed framework achieved better outcomes in terms of accuracy, true positive rate, precision, F-measure, kappa statistic, mean absolute error, and root mean squared error. Furthermore, it achieved the highest accuracy rates when compared with the state-of-the-art techniques. Results also indicated that the weighted distance function employed in EHC has improved the efficiency of proposed system and has shown the capability to be used by physicians for diagnostic advice. PMID- 29599941 TI - Systems and WBANs for Controlling Obesity. AB - According to World Health Organization (WHO) estimations, one out of five adults worldwide will be obese by 2025. Worldwide obesity has doubled since 1980. In fact, more than 1.9 billion adults (39%) of 18 years and older were overweight and over 600 million (13%) of these were obese in 2014. 42 million children under the age of five were overweight or obese in 2014. Obesity is a top public health problem due to its associated morbidity and mortality. This paper reviews the main techniques to measure the level of obesity and body fat percentage, and explains the complications that can carry to the individual's quality of life, longevity and the significant cost of healthcare systems. Researchers and developers are adapting the existing technology, as intelligent phones or some wearable gadgets to be used for controlling obesity. They include the promoting of healthy eating culture and adopting the physical activity lifestyle. The paper also shows a comprehensive study of the most used mobile applications and Wireless Body Area Networks focused on controlling the obesity and overweight. Finally, this paper proposes an intelligent architecture that takes into account both, physiological and cognitive aspects to reduce the degree of obesity and overweight. PMID- 29599942 TI - Impact of Fitness Status on the Optically Measured Hemodynamic Indexes. AB - The physiological characteristics of skin blood flow can be described in terms of the hemodynamic indices (HI). The HI is derived from the laser speckle characteristics, which are governed by the cutaneous blood flow. A miniaturized dynamic light-scattering sensor was used to measure the speckle pattern from the finger root. Three groups of subjects from 15 to 25 years of age were tested. The first group included subjects who are actively engaged in sport activities; the second group included subjects with low level of physical activity; and the third group included healthy controls with moderate physical activity. The HI parameters were measured prior to and after the performance of a determined physical load. As a marker of cardiovascular fitness (CVF), we used the postload decay rate of HI. We found that the hemodynamic response to the physical load provides a statistically significant correlation with the postload heart rate decay. It was also found that postocclusion increase of the arterial HI is more prominent in the group with higher physical activity. These results indicate that hemodynamic indices can be used as an additional marker for cardiovascular fitness level. PMID- 29599943 TI - Outlier Removal in Model-Based Missing Value Imputation for Medical Datasets. AB - Many real-world medical datasets contain some proportion of missing (attribute) values. In general, missing value imputation can be performed to solve this problem, which is to provide estimations for the missing values by a reasoning process based on the (complete) observed data. However, if the observed data contain some noisy information or outliers, the estimations of the missing values may not be reliable or may even be quite different from the real values. The aim of this paper is to examine whether a combination of instance selection from the observed data and missing value imputation offers better performance than performing missing value imputation alone. In particular, three instance selection algorithms, DROP3, GA, and IB3, and three imputation algorithms, KNNI, MLP, and SVM, are used in order to find out the best combination. The experimental results show that that performing instance selection can have a positive impact on missing value imputation over the numerical data type of medical datasets, and specific combinations of instance selection and imputation methods can improve the imputation results over the mixed data type of medical datasets. However, instance selection does not have a definitely positive impact on the imputation result for categorical medical datasets. PMID- 29599944 TI - A Novel Sleep Respiratory Rate Detection Method for Obstructive Sleep Apnea Based on Characteristic Moment Waveform. AB - Obstructive sleep apnea (OSA) affecting human's health is a kind of major breathing-related sleep disorders and sometimes leads to nocturnal death. Respiratory rate (RR) of a sleep breathing sound signal is an important human vital sign for OSA monitoring during whole-night sleeping. A novel sleep respiratory rate detection with high computational speed based on characteristic moment waveform (CMW) method is proposed in this paper. A portable and wearable sound device is used to acquire the breathing sound signal. And the amplitude contrast decreasing has been done first. Then, the CMW is extracted with suitable time scale parameters, and the sleep RR value is calculated by the extreme points of CMW. Experiments of one OSA case and five healthy cases are tested to validate the efficiency of the proposed sleep RR detection method. According to manual counting, sleep RR can be detected accurately by the proposed method. In addition, the apnea sections can be detected by the sleep RR values with a given threshold, and the time duration of the segmentation of the breath can be calculated for detailed evaluation of the state of OSA. The proposed method is meaningful for continued research on the sleep breathing sound signal. PMID- 29599945 TI - A Digital Compressed Sensing-Based Energy-Efficient Single-Spot Bluetooth ECG Node. AB - Energy efficiency is still the obstacle for long-term real-time wireless ECG monitoring. In this paper, a digital compressed sensing- (CS-) based single-spot Bluetooth ECG node is proposed to deal with the challenge in wireless ECG application. A periodic sleep/wake-up scheme and a CS-based compression algorithm are implemented in a node, which consists of ultra-low-power analog front-end, microcontroller, Bluetooth 4.0 communication module, and so forth. The efficiency improvement and the node's specifics are evidenced by the experiments using the ECG signals sampled by the proposed node under daily activities of lay, sit, stand, walk, and run. Under using sparse binary matrix (SBM), block sparse Bayesian learning (BSBL) method, and discrete cosine transform (DCT) basis, all ECG signals were essentially undistorted recovered with root-mean-square differences (PRDs) which are less than 6%. The proposed sleep/wake-up scheme and data compression can reduce the airtime over energy-hungry wireless links, the energy consumption of proposed node is 6.53 mJ, and the energy consumption of radio decreases 77.37%. Moreover, the energy consumption increase caused by CS code execution is negligible, which is 1.3% of the total energy consumption. PMID- 29599946 TI - Organic Boundary Location Based on Color-Texture of Visual Perception in Wireless Capsule Endoscopy Video. AB - This paper addresses the problem of automatically locating the boundary between the stomach and the small intestine (the pylorus) in wireless capsule endoscopy (WCE) video. For efficient image segmentation, the color-saliency region detection (CSD) method is developed for obtaining the potentially valid region of the frame (VROF). To improve the accuracy of locating the pylorus, we design the Monitor-Judge model. On the one hand, the color-texture fusion feature of visual perception (CTVP) is constructed by grey level cooccurrence matrix (GLCM) feature from the maximum moments of the phase congruency covariance and hue-saturation histogram feature in HSI color space. On the other hand, support vector machine (SVM) classifier with the CTVP feature is utilized to locate the pylorus. The experimental results on 30 real WCE videos demonstrate that the proposed location method outperforms the related valuable techniques. PMID- 29599947 TI - An Elderly Care System Based on Multiple Information Fusion. AB - With the development of social economy in the 21st century, and the rising of medical level, the aging of population have become a global trend. However lots of elderly people are in "empty nest" state. In order to solve the problem of high risk of daily life in this group, this paper proposed a method to integrate the information of video images, sound, infrared, pulse, and other information into the elderly care system. The whole system consists of four major components, that is, the main control board, the information acquisition boards, the server, and the client. The control board receives, processes and analyzes the data collected by the information acquisition boards, and uploads necessary information to the server, which are to be saved to the database. When something unexpected occurs to the elderly, the system will notify the relatives through the GPRS (general packet radio service) module. The system also provides an interface for the relatives to inquire the living status of the elderly through an app. The system can monitor the living status for the elderly with the characteristics of quick response, high accuracy, and low cost and can be widely applied to the elderly care at home.

AB - In view of the characteristics of high risk and high accuracy in cranio maxillofacial surgery, we present a novel surgical robot system that can be used in a variety of surgeries. The surgical robot system can assist surgeons in completing biopsy of skull base lesions, radiofrequency thermocoagulation of the trigeminal ganglion, and radioactive particle implantation of skull base malignant tumors. This paper focuses on modelling and experimental analyses of the robot system based on navigation technology. Firstly, the transformation relationship between the subsystems is realized based on the quaternion and the iterative closest point registration algorithm. The hand-eye coordination model based on optical navigation is established to control the end effector of the robot moving to the target position along the planning path. The closed-loop control method, "kinematics + optics" hybrid motion control method, is presented to improve the positioning accuracy of the system. Secondly, the accuracy of the system model was tested by model experiments. And the feasibility of the closed loop control method was verified by comparing the positioning accuracy before and after the application of the method. Finally, the skull model experiments were performed to evaluate the function of the surgical robot system. The results validate its feasibility and are consistent with the preoperative surgical planning. PMID- 29599949 TI - A New Remote Health-Care System Based on Moving Robot Intended for the Elderly at Home. AB - Nowadays, due to the growing need for remote care and the constantly increasing popularity of mobile devices, a large amount of mobile applications for remote care support has been developed. Although mobile phones are very suitable for young people, there are still many problems related to remote health care of the elderly. Due to hearing loss or limited movements, it is difficult for the elderly to contact their families or doctors via real-time video call. In this paper, we introduce a new remote health-care system based on moving robots intended for the elderly at home. Since the proposed system is an online system, the elderly can contact their families and doctors quickly anytime and anywhere. Besides call, our system involves the accurate indoor object detection algorithms and automatic health data collection, which are not included in existing remote care systems. Therefore, the proposed system solves some challenging problems related to the elderly care. The experiment has shown that the proposed care system achieves excellent performance and provides good user experience. PMID- 29599950 TI - Real-Time EEG Signal Enhancement Using Canonical Correlation Analysis and Gaussian Mixture Clustering. AB - Electroencephalogram (EEG) signals are usually contaminated with various artifacts, such as signal associated with muscle activity, eye movement, and body motion, which have a noncerebral origin. The amplitude of such artifacts is larger than that of the electrical activity of the brain, so they mask the cortical signals of interest, resulting in biased analysis and interpretation. Several blind source separation methods have been developed to remove artifacts from the EEG recordings. However, the iterative process for measuring separation within multichannel recordings is computationally intractable. Moreover, manually excluding the artifact components requires a time-consuming offline process. This work proposes a real-time artifact removal algorithm that is based on canonical correlation analysis (CCA), feature extraction, and the Gaussian mixture model (GMM) to improve the quality of EEG signals. The CCA was used to decompose EEG signals into components followed by feature extraction to extract representative features and GMM to cluster these features into groups to recognize and remove artifacts. The feasibility of the proposed algorithm was demonstrated by effectively removing artifacts caused by blinks, head/body movement, and chewing from EEG recordings while preserving the temporal and spectral characteristics of the signals that are important to cognitive research. PMID- 29599951 TI - Leukocyte Image Segmentation Using Novel Saliency Detection Based on Positive Feedback of Visual Perception. AB - This paper presents a novel method for salient object detection in nature image by simulating microsaccades in fixational eye movements. Due to a nucleated cell usually stained that is salient obviously, the proposed method is suitable to segment nucleated cell. Firstly, the existing fixation prediction method is utilized to produce an initial fixation area. Followed EPELM (ensemble of polyharmonic extreme learning machine) is trained on-line by the pixels sampling from the fixation and nonfixation area. Then the model of EPELM could be used to classify image pixels to form new binary fixation area. Depending upon the updated fixation area, the procedure of "pixel sampling-learning-classification" could be performed iteratively. If the previous binary fixation area and the latter one were similar enough in iteration, it indicates that the perception is saturated and the loop should be terminated. The binary output in iteration could be regarded as a kind of visual stimulation. So the multiple outputs of visual stimuli can be accumulated to form a new saliency map. Experiments on three image databases show the validity of our method. It can segment nucleated cells successfully in different imaging conditions. PMID- 29599952 TI - Optical Design with Narrow-Band Imaging for a Capsule Endoscope. AB - The study proposes narrow-band imaging (NBI) lens design of 415 nm and 540 nm of a capsule endoscope (CE). The researches show that in terms of the rate of accuracy in detecting and screening neoplastic and nonneoplastic intestinal lesions, the NBI system outperformed that of traditional endoscopes and rivaled that of chromoendoscopes. In the proposed NBI CE optical system, the simulation result shows the field of view (FOV) was 109.8 degrees ; the modulation transfer function (MTF) could achieve 12.5% at 285 lp/mm and 34.1% at 144 lp/mm. The relative illumination reaches more than 60%, and the system total length was less than 4 mm. Finally, this design provides high-quality images for a 300-megapixel 1/4" CMOS image sensor with a pixel size of 1.75 MUm. PMID- 29599953 TI - Intelligent Control Wheelchair Using a New Visual Joystick. AB - A new control system of a hand gesture-controlled wheelchair (EWC) is proposed. This smart control device is suitable for a large number of patients who cannot manipulate a standard joystick wheelchair. The movement control system uses a camera fixed on the wheelchair. The patient's hand movements are recognized using a visual recognition algorithm and artificial intelligence software; the derived corresponding signals are thus used to control the EWC in real time. One of the main features of this control technique is that it allows the patient to drive the wheelchair with a variable speed similar to that of a standard joystick. The designed device "hand gesture-controlled wheelchair" is performed at low cost and has been tested on real patients and exhibits good results. Before testing the proposed control device, we have created a three-dimensional environment simulator to test its performances with extreme security. These tests were performed on real patients with diverse hand pathologies in Mohamed Kassab National Institute of Orthopedics, Physical and Functional Rehabilitation Hospital of Tunis, and the validity of this intelligent control system had been proved. PMID- 29599954 TI - Efficient OCT Image Enhancement Based on Collaborative Shock Filtering. AB - Efficient enhancement of noisy optical coherence tomography (OCT) images is a key task for interpreting them correctly. In this paper, to better enhance details and layered structures of a human retina image, we propose a collaborative shock filtering for OCT image denoising and enhancement. Noisy OCT image is first denoised by a collaborative filtering method with new similarity measure, and then the denoised image is sharpened by a shock-type filtering for edge and detail enhancement. For dim OCT images, in order to improve image contrast for the detection of tiny lesions, a gamma transformation is first used to enhance the images within proper gray levels. The proposed method integrating image smoothing and sharpening simultaneously obtains better visual results in experiments. PMID- 29599955 TI - Enhancement of the Comb Filtering Selectivity Using Iterative Moving Average for Periodic Waveform and Harmonic Elimination. AB - A recurring problem regarding the use of conventional comb filter approaches for elimination of periodic waveforms is the degree of selectivity achieved by the filtering process. Some applications, such as the gradient artefact correction in EEG recordings during coregistered EEG-fMRI, require a highly selective comb filtering that provides effective attenuation in the stopbands and gain close to unity in the pass-bands. In this paper, we present a novel comb filtering implementation whereby the iterative filtering application of FIR moving average based approaches is exploited in order to enhance the comb filtering selectivity. Our results indicate that the proposed approach can be used to effectively approximate the FIR moving average filter characteristics to those of an ideal filter. A cascaded implementation using the proposed approach shows to further increase the attenuation in the filter stopbands. Moreover, broadening of the bandwidth of the comb filtering stopbands around -3 dB according to the fundamental frequency of the stopband can be achieved by the novel method, which constitutes an important characteristic to account for broadening of the harmonic gradient artefact spectral lines. In parallel, the proposed filtering implementation can also be used to design a novel notch filtering approach with enhanced selectivity as well.

PMID- 29599957 TI - A Comprehensive Method for Accurate Strain Distribution Measurement of Cell Substrate Subjected to Large Deformation. AB - Cell mechanical stretching in vitro is a fundamental technique commonly used in cardiovascular mechanobiology research. Accordingly, it is crucial to measure the accurate strain field of cell substrate under different strains. Digital image correlation (DIC) is a widely used measurement technique, which is able to obtain the accurate displacement and strain distribution. However, the traditional DIC algorithm used in digital image correlation engine (DICe) cannot obtain accurate result when utilized in large strain measurement. In this paper, an improved method aiming to acquire accurate strain distribution of substrate in large deformation was proposed, to evaluate the effect and accuracy, based on numerical experiments. The results showed that this method was effective and highly accurate. Then, we carried out uniaxial substrate stretching experiments and applied our method to measure strain distribution of the substrate. The proposed method could obtain accurate strain distribution of substrate film during large stretching, which would allow researchers to adequately describe the response of cells to different strains of substrate. PMID- 29599958 TI - Vision Diagnostics and Treatment System for Children with Disabilities. AB - Vision plays a crucial role in children's mental development. Therefore, early diagnosis of any vision disparities and implementation of a correct therapy is very important. However, carrying out such a procedure in case of young children and especially children with brain dysfunctions poses some limitations due to cooperation problems. The vision diagnostics and treatment (VisDaT) system presented in this paper is meant to help therapists in proper diagnosis and treatment involving such children. It utilizes a computer connected to two monitors and equipped with a specialized software. The main system components are as follows: an eye tracker recording child's eye movements and a digital camera monitoring online child's reactions. The system is equipped with a specialized software, which creates the opportunity to stimulate children's vision with a dedicated stimulus and post hoc analyses of recorded sessions, which enable making decision as to the future treatment. PMID- 29599959 TI - Assisted Protection Headphone Proposal to Prevent Chronic Exposure to Percussion Instruments on Musicians. AB - The effects of chronic exposure to high sound pressure levels (SPLs) are widely studied in the industry environment. However, the way that SPLs affect music students has not been thoroughly examined. In this paper, we study the SPL exposure of batucada students and we propose an assisted protection headphone as a part of e-health system. We measured the SPL reached during a regular percussion class. Pure-tone audiometries were performed to a set of percussion students. The gathered data were statistically analyzed. The assisted protection headphones and their operation are detailed and tested during a regular class. Our results show that 35% of the musicians present with a noise-induced hearing loss, considered as two frequencies with hearing loss of 25 dB or more or one frequency with a hearing loss of 30 dB or more. Our data also shows that those students that do not use any protection have a greater hearing loss. However, the students that use protection headphones are also suffering hearing loss. There might be a problem in the way that musicians are using the protection headphones. Our assisted protection headphones as a part of e-health measures can diminish the negative effects of percussion instruments for musicians. PMID- 29599960 TI - Association between maternal antidepressant use during pregnancy and autism spectrum disorder: an updated meta-analysis. AB - Studies have investigated the risk of autism spectrum disorder (ASD) in children exposed in utero to antidepressant, with inconsistent results. Given the substantial public health implications on this topic, here, we presented an updated meta-analysis of the association between maternal antidepressant use during pregnancy and ASD. Cochrane Library, EMBASE, PsycINFO, and PubMed databases were systematically searched. A random effects model was used to pool the adjusted relative risk (RR) for cohort studies and the adjusted odds ratio (OR) for case-control studies as well as their corresponding 95% confidence intervals (CIs). Meta-analysis restricted to sibling studies was also conducted. Publication bias was systematically assessed. Fourteen studies were identified (eight cohort studies and six case-control studies). Pooled adjusted RR for cohort studies (n = 2,839,980) was 1.13 (0.93-1.39) showed a non-significant association; while two studies were potentially missing from the test of publication bias, filled estimates also showed a non-significant association (filled RR 0.97, 95% CI 0.79-1.19). Pooled OR was 1.51 (1.15-1.99) for case control studies (n = 117,737) showed a significant association; two studies were potentially missing; however, the filled estimates suggested a non-significant association (filled OR 1.26, 95% CI 0.98-1.62). Analyses restricted to sibling studies also showed a non-significant association (RR 0.99, 95% CI 0.81-1.22). In summary, we did not evidence a significant association between maternal antidepressant use during pregnancy and ASD. PMID- 29599961 TI - Idiopathic omental infarction: One for conservative or surgical management? AB - Idiopathic omental infarction (IOI) is a rare cause of right-sided abdominal pain, mimicking serious surgical pathology. It occurs in <4 in 1000 cases of appendicitis. IOI can be a challenge to diagnose, as features may mimic appendicitis, and therefore in young patients, may only be discovered on laparoscopy. CT features can be diagnostic, but due to its rarity the diagnosis may be unclear. The literature supports both conservative management and surgical management (to expedite symptom resolution). We present a case of IOI and discuss our management and learning from the case. We discuss the utility of CT radiology, conservative management and the benefits of non-resection management, even at laparoscopy. PMID- 29599962 TI - Brown bowel syndrome, an unusual cause of sigmoid volvulus. AB - We report a case of a 79-year-old gentleman who presented to the emergency department with a 5-day history of abdominal pain, constipation, a progressively distending abdomen and new onset feculent vomiting on a background of a recent endoscopic decompression of a sigmoid volvulus. Investigations confirmed the presence of a recurrent sigmoid volvulus. Attempts to reduce this endoscopically failed and laparotomy with sub-total colectomy and ileostomy formation was performed. Histology from the resected specimen identified a distinct pathology, namely intestinal lipofuscinosis also known as brown bowel syndrome. Brown bowel syndrome is a recognized but rare complication of chronic long term malnutrition. It may present in a myriad of ways including atonia and, rarely, massive colonic dilatation, as in our case. PMID- 29599963 TI - Laparoscopic resection of a giant retroperitoneal melanotic schwannoma. AB - Background: Retroperitoneal schwannomas are extremely rare, as they account for only 3% of retroperitoneal tumors. Clinical symptoms are nonspecific and of late onset, meaning that these tumors are diagnosed at an advanced stage. Surgical resection is required for histological diagnosis and to prevent possible malignant transformation. Celioscopy offers numerous benefits, reducing postoperative pain and speeding up the patient's return to autonomy, but it can pose a real challenge due to the size of these lesions. Case presentation: We report a case of laparoscopic resection of a very large right-sided retroperitoneal schwannoma, with a particular histological form. Conclusion: Surgical resection in a single unit remains the golden rule, and a laparoscopy can be proposed when the diagnosis is beyond doubt. The large size of the retroperitoneal melanotic schwannomas, a common feature, increases surgical difficulties but is not a contraindication to this approach. PMID- 29599965 TI - Airborne protein concentration: a key metric for type 1 allergy risk assessment in home measurement challenges and considerations. AB - Background: Exposure to airborne proteins can be associated with the development of immediate, IgE-mediated respiratory allergies, with genetic, epigenetic and environmental factors also playing a role in determining the likelihood that sensitisation will be induced. The main objective of this study was to determine whether airborne concentrations of selected common aeroallergens could be quantified in the air of homes using easily deployable, commercially available equipment and analytical methods, at low levels relevant to risk assessment of the potential to develop respiratory allergies. Additionally, air and dust sampling were compared and the influence of factors such as different filter types on allergen quantification explored. Methods: Low volume air sampling pumps and DUSTREAM(r) dust samplers were used to sample 20 homes and allergen levels were quantified using a MARIA(r) immunoassay. Results: It proved possible to detect a range of common aeroallergens in the home with sufficient sensitivity to quantify airborne concentrations in ranges relevant to risk assessment (Limits of Detection of 0.005-0.03 ng/m3). The methodology discriminates between homes related to pet ownership and there were clear advantages to sampling air over dust which are described in this paper. Furthermore, in an adsorption-extraction study, PTFE (polytetrafluoroethylene) filters gave higher and more consistent recovery values than glass fibre (grade A) filters for the range of aeroallergens studied. Conclusions: Very low airborne concentrations of allergenic proteins in home settings can be successfully quantified using commercially available pumps and immunoassays. Considering the greater relevance of air sampling to human exposure of the respiratory tract and its other advantages, wider use of standardised, sensitive techniques to measure low airborne protein concentrations and how they influence development of allergic sensitisation and symptoms could accelerate our understanding of human dose-response relationships and refine our knowledge of thresholds of allergic sensitisation and elicitation via the respiratory tract. PMID- 29599964 TI - Syncytium calcium signaling and macrophage function in the heart. AB - Macrophages are traditionally viewed as a key component of the immunity defense system. Recent studies have identified resident macrophages in multiple organs including the heart, in which the cells perform their crucial role on tissue repair after myocardial infarction (MI). The cardiac-specific macrophages interdigitate with cardiomyocytes particularly at the atrioventricular node region. The integrative communication between macrophage and cardiomyocytes can modulate the contractile function of the heart. Coordinated control of intracellular calcium signaling and intercellular electrical conduction via the syncytium network underlie the synchronized beating of the heart. In this review article, we introduce the concept the syncytium calcium signaling in the cardiomyocytes can modulate gene expression in the resident macrophages and their integration with the cardiomyocytes. The cardiac macrophages originate from bone marrow stem cells, migrate to local via vessel, and settle down as a naturalization process in heart. As the macrophages perform on regulating electrical conduction, and accomplish post MI non-scared completed regeneration or partial regeneration with fibrotic scar at different stage of postnatal development, we understand that multiple functions of cardiac macrophage should carry on with diverse linages. The naturalization process in heart of macrophages to the cardiomyocytes serves important roles to control of electrical signaling and calcium-dependent contractile function of the heart. PMID- 29599967 TI - Prevalence of welfare outcomes in the weaner and finisher stages of the production cycle on 31 Irish pig farms. AB - Background: Knowledge on the most prevalent welfare problems for pigs in different production stages is required to improve herd management plans. Thirty one farrow-to-finish pig farms were visited between July and November 2015 to assess the welfare of pigs using the multicriteria approach of the Welfare Quality(r) protocol. On each farm, 6 pens were selected using proportionate stratified sampling in the first weaner (S1, 4 to 8 wks), second weaner (S2, 8 to 13 wks) and finisher stage (S3, 13 to 23 wks), excluding hospital pens. Each pen was observed for 10 min and the number of pigs affected by different welfare outcomes was recorded. The percentage of pigs affected was calculated and ranked to identify the most prevalent outcomes within each production stage. Differences between production stages were analysed using generalised linear mixed models for binomial data with pen within stage and farm as a random effect. Results: Tail and ear lesions showed the highest prevalence; however, large variation was observed between farms. In S1 the most prevalent welfare outcomes (presented as median prevalence) were poor body condition (4.4%), lethargic pigs (1.5%), scouring (20.3% of pens) and huddling (3.7%). In S2 and S3 outcomes related to injurious behaviour (tail lesions: 5.9% [S2] and 10.5% [S3], ear lesions: 9.1% [S2] and 3.3% [S3], and flank lesions: 0.4% [S2] and 1.3% [S3]), lameness (0.8% [S2] and 1.1% [S3]), bursitis (3.9% [S2] and 7.5% [S3]) and hernias (1.6% [S2] and 1.8% [S3]) were more prevalent. Conclusions: A large variation was observed for the recorded welfare outcomes corresponding to the different challenges pigs experience during the different stages of production on commercial pig farms. The prevalence of pigs affected by lesions caused by injurious behavior is a cause for concern and requires a collaborative approach to identify appropriate intervention strategies. This information could be used to further investigate appropriate benchmark values for different welfare outcomes that would assist the pig industry to develop appropriate health and welfare management plans to minimise welfare problems. At herd level such plans should include information on aspects of intervention, treatment, and the management of hospital pens as well as euthanasia. PMID- 29599966 TI - Effectiveness of icatibant for treatment of hereditary angioedema attacks is not affected by body weight: findings from the Icatibant Outcome Survey, a cohort observational study. AB - Background: Icatibant is a bradykinin B2-receptor antagonist used for the treatment of hereditary angioedema attacks resulting from C1-inhibitor deficiency. Treatment is not adjusted by body weight however the impact of body mass index (BMI) on the effectiveness of icatibant is not documented in the literature. We examined disease characteristics and icatibant treatment effectiveness in patients stratified by BMI in the Icatibant Outcome Survey, an ongoing, international, observational study monitoring the real-world safety and effectiveness of icatibant. Methods: Attack and treatment characteristics as well as outcomes following treatment with icatibant were compared among patients with underweight, normal, overweight, and obese BMI. Results: Data from 2697 icatibant treated attacks in 342 patients (3.5, 44.7, 34.8, and 17.0% patients of underweight, normal, overweight, and obese BMI, respectively) were analyzed. There was no significant difference in the frequency and severity of attacks across BMI groups, although obese patients tended to have more attacks of high severity. There was no impact of BMI on the frequency of laryngeal attacks, but patients with normal BMI had fewer cutaneous attacks and more abdominal attacks. Most attacks (71.9-83.8%) were treated with a single icatibant injection without the need for rescue with plasma-derived C1-inhibitor (pdC1-INH), regardless of BMI. Patients with obese BMI used pdC1-INH as rescue treatment more often (P < 0.0001; P = 0.0232 excluding 2 outliers) and treated attacks earlier than patients with normal BMI (P = 0.007). Furthermore, time to resolution and duration of attack were shorter for patients with high BMI (P < 0.001 for overweight and P < 0.05 for obese versus normal). Conclusion: Overall, icatibant was comparatively effective in treating attacks in patients across all BMI groups.Trial registration NCT01034969. PMID- 29599968 TI - Partial avulsion of the ulnaris lateralis and enthesiopathy of the lateral epicondyle of the humerus in a thoroughbred race horse. AB - Background: There is relatively little literature on elbow disease in the horse. The only published reports on soft tissue conditions describe collateral ligament and biceps brachii injuries. Case presentation: A three-year old Thoroughbred gelding presented with a history of acute onset right forelimb lameness of less than one week duration, one month after commencing training in a National Hunt racing yard. Physical examination and peri-neural anaesthesia failed to localise the lesion. Lameness was localised to the distal humerus by nuclear scintigraphy and intra-articular anaesthesia. A partial avulsion of the tendinous origin of the ulnaris lateralis and enthesiopathy of the lateral humeral epicondyle was diagnosed on ultrasonography. Ultrasonographic findings were loss of longitudinal fibre pattern, a discrete hypo-echoic region within the ulnaris lateralis tendon of origin, and remodelling of the lateral epicondyle of the right humerus at the site of the origin of the ulnaris lateralis. No abnormalities were identified on radiography. The lameness did not resolve with rest, but was successfully treated with extra corporal shockwave therapy (ECSWT) and intra-lesional corticosteroid injections. Conclusion: This is the first report of partial avulsion of the ulnaris lateralis and enthesiopathy of the lateral humeral epicondyle in the horse. In contrast to other reported soft tissue conditions of the elbow, this horse had a successful return to work. This case highlights the value of ultrasonography in assessing peri-articular soft tissues, and the importance of pain relief as treatment in some soft tissue injuries. PMID- 29599969 TI - Healthcare-associated fungal outbreaks: New and uncommon species, New molecular tools for investigation and prevention. AB - Outbreaks of healthcare-associated fungal infections have repeatedly been described over recent years, often caused by new or uncommon species. Candida auris, a recently described multidrug-resistant yeast species, is certainly the most worrisome species having caused several severe healthcare outbreaks of invasive infections, on four continents. Also, large nosocomial outbreaks due to uncommon fungal species such as Exserohilum rostratum and Sarocladium kiliense, were both linked to contamination of medical products, however the source of another outbreak, caused by Saprochaete clavata, remains unresolved. Furthermore, these outbreaks identified new populations under threat in addition to those commonly at risk for invasive fungal infections, such as immunosuppressed and intensive care unit patients. All of these outbreaks have highlighted the usefulness of a high level of awareness, rapid diagnostic methods, and new molecular typing tools such as Whole Genome Sequencing (WGS), prompt investigation and aggressive interventions, including notification of public health agencies. This review summarizes the epidemiological and clinical data of the majority of healthcare-associated outbreaks reported over the last 6 years caused by uncommon or new fungal pathogens, as well as the contribution of WGS as support to investigate the source of infection and the most frequent control measures used. PMID- 29599970 TI - Medication practice in hospitals: are nanosimilars evaluated and substituted correctly? AB - Introduction: This study investigates the drug selection and dispensing behaviour of hospital pharmacists of intravenous iron products including iron sucrose and iron sucrose similar, with special emphasis on substitution and interchangeability in France and Spain. Iron-carbohydrate complex drugs represent different available intravenous iron drugs and are part of the non-biological complex drug (NBCD) class, an expanding drug class with up to 30 brands available in intravenous pharmacotherapy and over 50 in clinical development. Follow-on versions of iron sucrose have appeared in some markets such as France and Spain, which were authorised by the generic approval pathway. However, differences in clinical efficacy and safety of iron sucrose similars compared with the reference originator drug Venofer have been observed, putting a question mark on their equivalence as assessed for authorisation and consequently their substitutability and interchangeability. Method: 70 French and 70 Spanish hospital pharmacists were surveyed via an online questionnaire on their formulary selection and dispensing behaviour of intravenous iron medicines. Results: There is little awareness about the characteristics of this class of drugs and the reported differences in safety and efficacy between iron sucrose and iron sucrose similars. In approximately 85% of cases the intravenous iron is chosen according to the hospital formulary. In 30% (France) and 34% (Spain) of cases an iron sucrose similar was dispensed because the formulary requires dispensing an alternative lower cost drug when available. In 26% (France) and 52% (Spain) of cases the physician is not informed on such a medication change using a similar product. Conclusions: Evaluation of NBCD similars for substitution and interchange by hospital pharmacists is rarely based on scientific and clinical criteria but rather on cost aspects only, which does not ensure safe, efficacious and cost-effective use of such drugs. PMID- 29599971 TI - Time and age trends in morning and evening protein intakes of German children and adolescents. AB - The present study describes time and age trends in morning and evening protein intakes and sources among German children and adolescents from 1985 to 2014. A total of 9757 three-day weighed dietary records of 1246 3- to 18-year-old participants of the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study were analysed using polynomial mixed-effects regression models. Morning protein intake increased over the study period by approximately 1 % of morning energy intake (linear trend P < 0.0001), with the youngest and the oldest children having the highest protein intake (linear, quadratic trend P < 0.0001). Evening protein intake increased over time by approximately 2 % of evening energy intake in girls (linear trend P < 0.0001) and 1 % of evening energy intake in boys (quadratic trend P = 0.0313), with decreasing intake with age (girls: linear trend P < 0.0001; boys: linear trend P = 0.0963). Time trends were largely due to increases in protein from 'starchy foods'. In conclusion, morning and evening protein intakes increased modestly between 1985 and 2014; these increases were, however, not accompanied by increases in traditional protein sources (i.e. meat or dairy products). PMID- 29599972 TI - Effects of fish and krill oil on gene expression in peripheral blood mononuclear cells and circulating markers of inflammation: a randomised controlled trial. AB - Marine n-3 (omega-3) fatty acids alter gene expression by regulating the activity of transcription factors. Krill oil is a source of marine n-3 fatty acids that has been shown to modulate gene expression in animal studies; however, the effect in humans is not known. Hence, we aimed to compare the effect of intake of krill oil, lean and fatty fish with a similar content of n-3 fatty acids, and high oleic sunflower oil (HOSO) with added astaxanthin on the expression of genes involved in glucose and lipid metabolism and inflammation in peripheral blood mononuclear cells (PBMC) as well as circulating inflammatory markers. In an 8 week trial, healthy men and women aged 18-70 years with fasting TAG of 1.3-4.0 mmol/l were randomised to receive krill oil capsules (n 12), HOSO capsules (n 12) or lean and fatty fish (n 12). The weekly intakes of marine n-3 fatty acids from the interventions were 4654, 0 and 4103 mg, respectively. The mRNA expression of four genes, PPAR gamma coactivator 1A (PPARGC1A), steaoryl-CoA desaturase (SCD), ATP binding cassette A1 (ABCA1) and cluster of differentiation 40 (CD40), were differently altered by the interventions. Furthermore, within-group analyses revealed that krill oil down-regulated the mRNA expression of thirteen genes, including genes involved in glucose and cholesterol metabolism and beta oxidation. Fish altered the mRNA expression of four genes and HOSO down-regulated sixteen genes, including several inflammation-related genes. There were no differences between the groups in circulating inflammatory markers after the intervention. In conclusion, the intake of krill oil and HOSO with added astaxanthin alter the PBMC mRNA expression of more genes than the intake of fish. PMID- 29599973 TI - Effects of Lactobacillus acidophilus on the growth performance and intestinal health of broilers challenged with Clostridium perfringens. AB - Background: Clostridium perfringens is the main etiological agent of necrotic enteritis. Lactobacilli show beneficial effects on intestinal health in infectious disease, but the protective functions of lactobacilli in C. perfringens-infected chickens are scarcely described. This study examined the effects of Lactobacillus acidophilus (L. acidophilus) on the growth performance and intestinal health of broiler chickens challenged with Clostridium perfringens (C. perfringens) over a 28-day period. Using a 2 * 2 factorial arrangement of treatments, a total of 308 1-day-old male Arbor Acres broiler chicks were included to investigate the effects of Lactobacillus acidophilus (L. acidophilus) on the growth performance and intestinal health of broiler chickens challenged with Clostridium perfringens (C. perfringens) during a 28-day trial. Results: During infection (d 14-21), C. perfringens challenge decreased the average daily gain (P < 0.05), and increased feed conversion ratio and the mortality rate (P < 0.05). However, dietary supplementation with L. acidophilus increased the body weight of C. perfringens-infected broilers on d 21 (P < 0.05), and tended to decrease the mortality (P = 0.061). C. perfringens challenge decreased the villus height (P < 0.05), the ratio of villus height to crypt depth (P < 0.05) and OCLN (occludin) mRNA expression (P < 0.05), and increased the pro-inflammatory cytokine expression in the spleen and jejunum, the intestinal populations of C. perfringens and Escherichia (P < 0.05), and the serum content of endotoxin (P < 0.05), regardless of L. acidophilus supplementation. In contrast, dietary L. acidophilus reducedthe intestinal lesion score of challenged broilers (P < 0.05), the mRNA expression of pro-inflammatory cytokines, ileal populations of Escherichia and serum endotoxin content (P < 0.05), but increased the intestinal Lactobacillus populations (P < 0.05), irrespective of C. perfringens challenge. Conclusion: Dietary addition of L. acidophilus could improve the intestinal health and reduce the mortality of broilers suffering from necrotic enteritis. PMID- 29599974 TI - Tuberculosis in South Asia: a tide in the affairs of men. AB - Background: Tuberculosis (TB) remains the most common cause of infectious disease deaths worldwide. What is perhaps less appreciated is that the caseload of tuberculosis patients in South Asia is staggering.South Asia has almost 40% of the global TB burden with 4,028,165 cases in 2015. This region also has a disproportionate share of TB deaths (681,975 deaths, 38% of the global burden). Worldwide just 12.5% of TB cases are in HIV positive individuals, but much research and investment has focused on HIV-associated TB. Only 3.5% of patients with tuberculosis in South Asia have HIV co-infection. Not surprisingly with such a huge burden of disease, this region has an estimated 184,336 multi drug resistant (MDR) cases among notified TB cases which accounts for a third of global MDR burden. Crucially, at least 70% of the estimated MDR cases remain untreated in this region and MDR treatment success ranged from only 46% for India to 88% for Sri Lanka in the 2012 cohort that received treatment. This region represents many of the drivers of the modern TB epidemic: rapid urbanization and high density populations with dramatically rising incidence of diabetes, a burgeoning and largely unregulated private sector with escalating drug resistance and high air pollution both outdoor and household. Conclusion: From bacterial biochemistry to policy implementation, we suggest ways in which South Asia can seize the opportunity lead global TB elimination by demonstrating feasibility in some of the world's most densely populated cities and remotest reaches of the Himalayas. Clearly political will is essential, but we cannot defeat TB without understanding how to eliminate it in South Asia. PMID- 29599975 TI - Exosomes as a novel pathway for regulating development and diseases of the skin. AB - Exosomes are one of the most potent intercellular communicators, which are able to communicate with adjacent or distant cells. Exosomes deliver various bioactive molecules, including membrane receptors, proteins, mRNA and microRNA, to target cells and serve roles. Recent studies have demonstrated that exosomes may regulate the functions and diseases of the skin, which is the largest organ of the human body. The abnormal functions of the skin lead to the progression of scleroderma, melanoma, baldness and other diseases. A previous study has demonstrated that epithelial progenitor cells are rich in several subunits of exosomes that may maintain the proliferative capacity of these epithelial progenitor cells, which is essential for the development of the epidermis. Exosomes derived from human adipose mesenchymal stem cells accelerate skin wound healing by optimizing fibroblast properties; this is beneficial for the recovery of postoperative and other wounds. Exosomes derived from adipocytes promote melanoma migration and invasion through fatty acid oxidation; therefore, in the clinic, it may be possible to improve the prognosis of patients with melanoma by reducing their body fat content. Exosomes derived from keratinocytes modulate melanocyte pigmentation, which has been utilized as a novel mechanism for the regulation of pigmentation in conditions including Moynahan syndrome and albinism. Meanwhile, scleroderma patients with vascular abnormalities may experience decreased serum exosome levels; it may therefore be possible to detect the exosome content in sera in order to diagnose and treat scleroderma. In addition, the use of exosomes has been suggested to promote or enhance hair growth, which has been demonstrated to be highly effective. These studies have provided new opportunities and therapeutic strategies for understanding how exosomes regulate intercellular communication in pathological processes of the skin. PMID- 29599976 TI - High sensitivity 8-color flow cytometry assay for paroxysmal nocturnal hemoglobinuria granulocyte and monocyte detections. AB - Flow cytometry is the gold standard in diagnosis of paroxysmal nocturnal hemoglobinuria (PNH) by detecting the absence of glycol-phosphatidyl inositol (GPI)-linked protein expression on granulocyte and monocyte surfaces. However, the current assays are not optimized and require improvement, particularly in reducing background fluorescence and optimizing sensitivity and specificity. With more fluorochromes available and with advances in instrument engineering, rare populations may be identified with high sensitivity. The present study assessed an 8-color combination of comprehensive GPI-linked markers, namely fluorescein labeled proaerolysin (FLAER), cluster of differentiation 157 (CD157), CD24 and CD14, and the lineage markers for granulocyte (CD15) and monocyte (CD64) cells to detect PNH clones. Additionally, to optimize the PNH flow assay, a 'dump' channel was used, comprised of CD5 and CD19, to exclude non-specific binding in order to reduce background. This method aimed to improve sensitivity and reduce the background to create an optimized PNH flow cocktail. The results demonstrated that the current 4-color PNH combination identifies a CD55- and FLAER+ population that is not PNH clones. By contrast, the 8-color panel delineated PNH clones from both monocyte and granulocytes by using granulocyte antigen (CD15) and monocyte antigen (CD64) as a gating strategy. The sensitivity was 0.01% for granulocytes and 0.05% for monocytes with an acquisition of 100,000 monocyte and granulocyte events. The background on a normal whole blood sample was 0.00076% on monocytes and 0.00277% on granulocytes. Thus, overall, the 8-color PNH assay exhibited high levels of specificity and sensitivity. The 8-color combination facilitated the improvement and enhancement of sensitivity in PNH clone identification, and may provide a useful tool for pathologists in PNH diagnosis and for monitoring patients at risk of developing classical/hemolytic PNH, to enable treatment to be delivered promptly. PMID- 29599977 TI - Computer-aided design of temozolomide derivatives based on alkylglycerone phosphate synthase structure with isothiocyanate and their pharmacokinetic/toxicity prediction and anti-tumor activity in vitro. AB - Despite the development of temozolomide (TMZ), a novel type of glioma therapeutic drug, malignant glioma remains to cause severe damage to human health. The present study aimed to utilize the molecular biological differences between tumor and normal cells to design TMZ derivatives with improved selectivity and targeting using computer-aided drug design (CADD). Taking alkylglycerone phosphate synthase (AGPS) as a target, a 3D structure-activity relationship model was built using CADD technology; molecular docking of isothiocyanate (ITC) and TMZ compounds was conducted; ITC-TMZ derivatives were designed; and predictions on the absorption, distribution, metabolism and excretion (ADME) processes and toxicity of the ITC-TMZ derivatives were established in order to obtain improved understanding of the structure-activity relationship of the candidate compounds. Using these techniques, it was identified that the docking scores of the structural derivatives S1-9 were higher than that of TMZ. Additionally, S3, -6, 7, -8, -9 and -10 exhibited enhanced ADME and similar toxicity to that of TMZ. The half maximal inhibitory concentrations of the CADD derivatives were also assessed in the glioma U87MG and U251 cell lines, and the activities of S1, -3, 8 and -10 were determined to be greater than that of TMZ, suggesting their potential as anti-cancer drugs with adequate AGPS targeting, ADME/toxicity and anti-tumor activity. PMID- 29599979 TI - The phenotype, psychotype and genotype of bruxism. AB - Bruxism is a jaw muscle activity that involves physio-pathological, psycho social, hereditary and genetic factors. The purpose of this study was to determine the associations between self-reported bruxism, anxiety, and neuroticism personality trait with the rs6313 polymorphism in the gene HTR2A. A sample of 171 subjects of both sexes (14-53 years of age) was included. The control group (group 1, n=60) exhibited no signs or symptoms of bruxism. The case group had signs and symptoms of bruxism (n=112) and was subdivided into group 2, bruxism during sleep (n=22); group 3, awake bruxism (n=44); and group 4 combined bruxism (n=46). As diagnostic tools, the Self-Reported Bruxism Questionnaire (SBQ), the Beck Anxiety Inventory (BAI) and the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A) were used. HTR2A (rs6313) SNPs were determined by qPCR for all the participants. The packages SPSS, maxLik and EPI-INFO were used for data analysis. The combined bruxism group reported higher scores in bruxism symptoms, mean = 32.21; anxiety symptoms, mean = 14.80; and neuroticism, mean = 3.26. Combined bruxism was associated with a higher degree of neuroticism (OR=15.0; CI 1.52-148.32) and anxiety in grade 3-moderate (OR=3.56; CI 1.27 10.03), and grade 4-severe (OR=8.40; CI 1.45-48.61), as determined using EPISODE computer software. Genotypic homogeneity analysis revealed no significant differences in allele frequency (P=0.612) among the four groups. The population was in Hardy-Weinberg equilibrium (maxLik package). In conclusion, the three instruments confirm traits of bruxism, anxiety and neuroticism in individuals with bruxism. These data were ratified when the sample was divided by genotypic homogeneity. On the other hand, there was no significant difference between the groups in the SNPs rs6313 from the HTR2A gene. PMID- 29599978 TI - Association between heme oxygenase-1 gene promoter polymorphisms and cancer susceptibility: A meta-analysis. AB - Numerous studies have focused on the association between heme oxygenase-1 (HO-1) gene promoter polymorphisms and susceptibility to cancer; however, results remain ambiguous. The present systematic Human Genome Epidemiology review and meta analysis aimed to clarify this association. A systematic search was used to assess the association of HO-1 gene polymorphisms with cancer susceptibility in the PubMed, Web of Science, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure databases, with all reviewed studies published before April 10, 2017. Review Manager 5.3 and Stata 12.0 software were used to perform the meta-analysis. A total of 14 studies were included in the analysis. Overall, no significant associations of the HO-1 (GT)n and T(-413)A polymorphisms with cancer susceptibility were identified. However, subgroup analyses by ethnicity and cancer type indicated that the LL and L-allele (LL+LS) genotypes of HO-1 (GT)n were associated with increased susceptibility to cancer compared with the SS+SL and SS genotypes in the following subgroups: East Asian [LL+LS vs. SS: odds ratio (OR)=1.51, 95% confidence interval (CI)=1.11-2.05, P=0.0003; LL vs. SS+SL: OR=1.44, 95% CI=1.04-2.01, P=0.03; LL vs. SS: OR=1.64, 95% CI=1.07-2.52, P=0.02]; squamous cell carcinoma (LL+LS vs. SS: OR=1.78, 95% CI=1.35-2.34, P<0.05; LL vs. SS+SL: OR=1.71, 95% CI=1.34-2.18, P<0.05; LL vs. SS: OR=2.26, 95% CI =1.62-3.14, P<0.05); and digestive tract cancer + East Asian (LL+LS vs. SS: OR=1.56, 95% CI=1.22-1.98, P<0.05; LL vs. SS: OR=1.80, 95% CI=1.06-3.05, P<0.05). These findings indicated that there was no association of the HO-1 (GT)n and T(-413)A polymorphisms with cancer susceptibility, while the L-allele genotypes (LL and LS) of HO-1 (GT)n may be susceptibility factors for cancer in East Asian, digestive tract cancer in East Asian and squamous cell carcinoma populations. Due to limitations of the reviewed studies, additional large-scale and refined studies are now required to confirm the present findings. PMID- 29599980 TI - Gender differences in the regulation of MLC20 phosphorylation and smooth muscle contraction in rat stomach. AB - Evidence of sex-related differences in gastrointestinal (GI) functions has been reported in the literature. In addition, various GI disorders have disproportionate prevalence between the sexes. An essential step in the initiation of smooth muscle contraction is the phosphorylation of the 20-kDa regulatory myosin light chain (MLC20) by the Ca2+/calmodulin-dependent myosin light chain kinase (MLCK). However, whether male stomach smooth muscle inherits different contractile signaling mechanisms for the regulation of MLC20 phosphorylation from that in females has not been established. The present study was designed to investigate sex-associated differences in the regulation of MLC20 phosphorylation and thus muscle contraction in gastric smooth muscle cells (GSMCs). Experiments were performed on GSMCs freshly isolated from male and female rats. Contraction of the GSMCs in response to acetylcholine (ACh), a muscarinic agonist, was measured via scanning micrometry in the presence or absence of the MLCK inhibitor, ML-7. Additionally, the protein levels of MLC20, MLCK and phosphorylated MLC20 were measured by ELISA. The protein levels of MLC20 and MLCK were indifferent between the sexes. ACh induced greater contraction (P<0.05) as well as greater MLC20 phosphorylation (P<0.05) in male GSMCs compared with female. Pretreatment of GSMCs with ML-7 significantly reduced the ACh induced contraction (P<0.05) and MLC20 phosphorylation (P<0.05) in the male and female cells, and notably, abolished the contractile differences between the sexes. In conclusion, MLC20 phosphorylation and thus muscle contraction may be activated to a greater extent in male rat stomach compared with that in females. PMID- 29599982 TI - Solitary primary intracranial leptomeningeal glioblastoma invading the normal cortex: Case report. AB - Solitary primary intracranial leptomeningeal glioma (PLG) is a rare entity of glioma. PLG arises from the heterotopic glial tissue in the subarachnoid space and usually grows there without parenchymal invasion. The present study reported a case of solitary PLG, pathologically diagnosed as glioblastoma, that invaded the temporal cortex and finally disseminated to the spinal cord. A 55-year-old woman had headaches and visited Nihon University, Itabashi Hospital. Head magnetic resonance imaging showed a solid mass mainly located in the right middle fossa extending to the frontal base with strong enhancement effect after contrast medium injection. A conventional angiogram showed a tumor arising from the middle meningeal artery. Fronto-temporal craniotomy was performed to remove the tumor. During reflection of the dura matter, there were numerous small vessels connecting the dura matter and the cortical surface. The tumor was located in the Sylvian fissure and extended around the middle cerebral artery. The border between the tumor and the normal temporal lobe was unclear. Temporal lobectomy was done, but the tumor was left around the perforators of the middle cerebral artery. Hematoxylin and eosin staining showed typical glioblastoma with high cellularity, mitosis, pseudopallisading and vascular proliferation. The tumor cells were immunohistochemically negative for isocitrate dehydrogenase (IDH)1 R132H indicating glioblastoma, IDH-wild type. The patient received chemotherapy and radiation therapy, and was discharged from the hospital. Six months later, local regrowth and spinal dissemination were found. Despite additional chemotherapy and radiation therapy, the tumor became uncontrollable and the patient succumbed. Only 15 cases of solitary PLGs have been reported previously. The IDH status of these tumors have not been investigated in most cases; however, pathological grading varies from lower to higher grade glioma. Together with the pathological difference of astrocytic or oligodendrocytic tumors, solitary PLGs may develop due to various gene alterations similar to intra-axial gliomas. PMID- 29599981 TI - Oxidative stress response induced by chemotherapy in leukemia treatment. AB - Oxidative stress (OS) has been linked to the etiology and development of leukemia as reactive oxygen species (ROS) and free radicals have been implicated in leukemogenesis. OS has beneficial and deleterious effects in the pathogenesis and progression of leukemia. High-dose chemotherapy, which is frequently used in leukemia treatment, is often accompanied by ROS-induced cytotoxicity. Thus, the utilization of chemotherapy in combination with antioxidants may attenuate leukemia progression, particularly for cases of refractory or relapsed neoplasms. The present review focuses on exploring the roles of OS in leukemogenesis and characterizing the associations between ROS and chemotherapy. Certain examples of treatment regimens wherein antioxidants are combined with chemotherapy are presented, in order to highlight the importance of antioxidant application in leukemia treatment, as well as the conflicting opinions regarding this method of therapy. Understanding the underlying mechanisms of OS generation will facilitate the elucidation of novel approaches to leukemia treatment. PMID- 29599983 TI - Patterning and fluorescence tuning of quantum dots with haptic-interfaced bubble printing. AB - Semiconductor quantum dots (QDs) are attractive for a wide range of applications such as displays, light-emitting devices, and sensors due to their properties such as tunable fluorescence wavelength, high brightness, and narrow bandwidth. Most of the applications require precise patterning of QDs with targeted properties on solid-state substrates. Herein, we have developed a haptic interfaced bubble printing (HIBP) technique to enable high-resolution (510 nm) high-throughput (>104 MUm s-1) patterning of QDs with strong emission tunability and to significantly enhance the accessibility of the technique via a smartphone device. The scalability and versatility of the HIBP are demonstrated in our arbitrary patterning of QDs on plasmonic substrates. A detailed study of plasmonic and photothermal interactions is performed via programmed stage movements to realize tunability of the emission wavelength and lifetime. Finally, the influence of the hand movement on the properties of the printed QDs in terms of emission wavelength tuning from yellow to blue is established. This work provides a single-step macroscale platform to manipulate nanoscale properties at high resolution and high throughput. PMID- 29599985 TI - Reluctant reviewers? Publons may help. PMID- 29599984 TI - A bibliometric analysis of the global research on biosimilars. AB - Background: Biosimilars could be a promising option to help decrease healthcare costs and expand access to treatment. There is no previous evidence of a global bibliometric analysis on biosimilars. Therefore, we aimed to assess the quantity and quality of worldwide biosimilars research. Methods: We performed a bibliometric analysis using documents about biosimilars published until December 2016 in journals indexed in Scopus. We extracted the annual research, languages, countries, journals, authors, institutions, citation frequency, and the metrics of journals. The data were quantitatively and qualitatively analyzed using Microsoft Excel 2013. Additional information about authors' participation was obtained using the R-package Bibliometrix. Publication activity was adjusted for the countries by population size. Also, author co-citation analysis and a term co occurrence analysis with the terms included in the title and abstract of publications was presented as network visualization maps using VOSviewer. Results: A total of 2330 biosimilar-related documents identified in the Scopus database, most of them were articles (1452; 62.32%). The number of documents published had an exponential increased between 2004 and 2016 (p < 0.001). The United States was the country with the highest production with 685 (29.40%) documents followed by Germany and UK with 293 (12.58%) and 248 (10.64%), respectively. Switzerland (11.05), Netherlands (5.85) and UK (3.83) showed the highest per capita ratio. The highest citation/article ratio were for the Netherlands (28.06), Spain (24.23), and France (20.11). Gabi Journal published 73 (3.13%) documents; both Biopharm International and Pharmaceutical Technology and Mabs, 41 (1.76%). Three out of top ten journals were Trade publications. Amgen Incorporated from the USA was the most prolific institution with 51 documents followed by Pfizer Inc. with 48. Terms about specific diseases and drugs were found in recent years, compared with terms such as legislation, structure, protein, dose and generic in the early years. Conclusions: Research production and publication of documents on biosimilars are increasing. The majority of publications came from high-income countries. The trends in terminology use are according to state of the art in the topic, and reflects the interest in the utilization of biosimilars in diseases who are expected to obtain benefits of its use. PMID- 29599986 TI - A discussion paper on stigmatizing features of diabetes. AB - Aim: This manuscript aims to describe stigmatizing features of diabetes. Design: This article presents a narrative review of literature pertaining to stigma surrounding diabetes in different contexts. Methods: A literature search was conducted in CINAHL, PubMed and Web of Science for qualitative studies published between 2007-2017. The search was completed using various combinations of diabetes, T1DM, T2DM, stigma, social/public stigma, internalized/self-stigma, stigmatization and diabetes-related stigma in English. The reviewers then independently reviewed the eligible studies (N = 18) to extract data. Results: From the 18 studies included in this narrative review, seven features related to stigma in diabetes were identified. People with diabetes were most notably considered and stigmatized as being "sick," "death reminder," "rejected marriage candidate," "self-inflicting," "contagiousness," "requiring a dietary modification" and "drunk or drug abuser." PMID- 29599987 TI - The care-planning conference: Exploring aspects of person-centred interactions. AB - Aim: The aim of this study was to describe the care-planning conference from the participants' and researchers' perspectives, focusing on exploring aspects of person-centred interactions. Design: A single-instrumental, qualitative case study design was used describing a care-planning conference taking place in the home of an older woman and her daughter. Methods: Data collection consisted of observation and digital recording of the care-planning conference and individual interviews with all the participants before and after the conference. Data were analysed in several phases: first, a narrative description followed by a general description and, thereafter, qualitative content analysis. Results: The findings revealed that the care-planning conference conducted had no clear purpose and did not fulfil all parts of the planning process. Three themes emerged related to aspects of person-centred interactions. The theme "expectations meet reality" showed different expectations, and participants could not really connect during the conference. The theme "navigate without a map" revealed health professionals' lack of knowledge about the care-planning process. The theme "lose the forest for the trees" described that the conference was conducted only as part of the health professionals' duties. Management and healthcare professionals cannot automatically assume that they are delivering person-centred care. Healthcare professionals need to be sensitive to the context, use the knowledge and tools available and continuously evaluate and reassess the work carried out.

AB - Aim: Postpartum depression is a mood disorder that commonly affects women during the early postpartum period. The objective of this study was to analyse the association of postpartum depression with drugs (including contraceptive devices and implants) with spontaneously reported adverse events reported in the US Food and Drug Administration Adverse Event Reporting System database. Design: Retrospective study. Method: Reports of postpartum depression events between 2004 2015 were analysed with a reporting odds ratio (ROR) algorithm. The Medical Dictionary for Regulatory Activities was used to identify postpartum depression. Results: The reporting odds ratios (95% confidence intervals, CI) of levonorgestrel (an intrauterine device with progestogen), etonogestrel (a hormonal contraceptive implant), sertraline and drospirenone (an oral contraceptive) were 12.5 (8.7-18.0), 14.0 (8.5-22.8), 12.2 (6.5-23.1) and 5.4 (2.7-10.9) respectively. Among the drugs in the US Food and Drug Administration Adverse Event Reporting System database, the use of contraceptives or an intrauterine device with progestogen might convey risk for postpartum depression. PMID- 29599989 TI - What is desirable care in the opinion of formal and informal caregivers in nursing-home care for patients with dementia? AB - Aim: To examine care characteristics related to desirable care as reported by formal and informal caregivers in Dutch Psycho-geriatric nursing homes for patients with dementia. Design: Qualitative exploratory study. Methods: The sample consisted of four nursing homes. In each home, semi-structured interviews were conducted with a manager, a quality advisor or head nurse, a daily care supervisor and an informal caregiver. The findings were analysed by labelling and coding the text fragments. Results: The 16 semi-structured interviews contained 60 discussion items. The 16 items that were shared by the four interviewee categories were clustered into the following six major themes: good quality of care; poor quality of care; elements of a vision; extra hands; bureaucracy; and formal caregivers. PMID- 29599990 TI - Patients' experiences of the transcatheter aortic valve implantation trajectory: A grounded theory study. AB - Aim: The aim of this study was to explore how patients experienced the recovery process from transcatheter aortic valve implantation. Design: A qualitative approach where in-depth interviews were used. Method: Eleven men and eight women undergoing transcatheter aortic valve implantation were individually interviewed 6 months after transcatheter aortic valve implantation. Grounded theory was used for the analysis. Results: The analysis generated the core concept "A journey of balancing between life-struggle and hope" connected to descriptive, bipolar categories. Before transcatheter aortic valve implantation patients not only felt threatened but also experienced hope. The rehabilitation phase was described as demanding or surprisingly simple. At the 6 months follow-up patients were pleased to return to life, however, still struggling with limitations. To feel hope is essential for transcatheter aortic valve implantation patients' well-being, both before and during the recovery process. It is important that healthcare professionals not only support hopeful thinking but also take time to discuss and prepare patients, talk about concerns and build confidence. Individual plans for rehabilitation should be designed. PMID- 29599991 TI - Older people and their families' perceptions about their experiences with interprofessional teams. AB - Aim: To examine older people and their families' perceptions about their experiences with interprofessional teams. Design: Naturalistic inquiry using qualitative descriptive methods to provide a comprehensive summary of older people and their families' experiences with interprofessional teams. Methods: Interviews were conducted with 22 people from 11 families. The families had experiences with teams in a variety of settings, such as community, residential care and hospital. Data were analysed using inductive content analysis. NiVivo was used to record preliminary codes. Analysis included comparing and contrasting families' experiences. Results: Older people and their families wanted communication about what was going on, regardless of whether the news was good, bad or unknown. They also wanted care that took the concerns of the older person into consideration. Communication was a necessary ingredient to ensuring that the older person's unique concerns were known to the interprofessional team. These percepectives were discussed in the themes of communication and patient-centred care. PMID- 29599992 TI - Using a new interrater reliability method to test the modified Oulu Patient Classification instrument in home health care. AB - Aim: To test the interrater reliability of the modified Oulu Patient Classification instrument, using a multiple parallel classification method based on oral case presentations in home health care in Norway. Design: Reliability study. Methods: Data were collected at two municipal home healthcare units during 2013-2014. The reliability of the modified OPCq instrument was tested using a new multiple parallel classification method. The data material consisted of 2 010 parallel classifications, analysed using consensus in per cent and Cohen's kappa. Cronbach's alpha was used to measure internal consistency. Results: For parallel classifications, consensus varied between 64.78-77.61%. Interrater reliability varied between 0.49-0.69 (Cohen's kappa), the internal consistency between 0.81 0.94 (Cronbach's alpha). Analysis of the raw scores showed 27.2% classifications had the same points, 39.1% differed one point, 17.9% differed two points and 16.5% differed >=3 points. PMID- 29599993 TI - A mixed methods study of Tai Chi exercise for patients with chronic heart failure aged 70 years and older. AB - Aims and objectives: This study aimed to evaluate Tai Chi group training among patients with chronic heart failure (CHF) aged 70 years and older. Background: Physical activity is recommended for CHF treatment. Tai Chi is found to be beneficial to different patient groups, although few studies focus on older patients with CHF. Design: A mixed methods study. Participants were randomly assigned to Tai Chi training twice a week for 16 weeks (N = 25) or control (N = 20). Quantitative data were collected at baseline, at the end of the training period and 6 months after training, assessing self-rated fatigue and quality of life, natriuretic peptides and physical performance. Individual qualitative interviews were conducted with participants (N = 10) in the Tai Chi training group. Results: No statistical differences between the Tai Chi training group and the control group in quality of life or natriuretic peptides was found. After 16 weeks, the training group tended to rate more reduced activity and the control group rated more mental fatigue. Participants in the training group rated increased general fatigue at follow-up compared with baseline. Qualitative interviews showed that Tai Chi training was experienced as a new, feasible and meaningful activity. The importance of the leader and the group was emphasized. Improvements in balance were mentioned and there was no physical discomfort. Conclusion: Tai Chi was experienced as a feasible and meaningful form of physical exercise for patients with CHF aged over 70 years despite lack of achieved health improvement. Further investigations, using feasibility and meaningfulness as outcome variables seems to be useful. PMID- 29599994 TI - Course of maternal fatigue and its associated factors during the first 6 months postpartum: a prospective cohort study. AB - Aims: To identify the course of maternal fatigue during the first 6 months postpartum and to determine factors associated with it. Design: A prospective cohort study. Methods: Women (N = 2,697) in 13 Japanese hospitals provided longitudinal data using self-report questionnaires at five time points. Maternal fatigue was assessed using the Postnatal Accumulated Fatigue Scale. We focused on the effect of maternal age and parity on the course of maternal fatigue and used a mixed between/within-subjects analysis of variance. Factors associated with maternal fatigue were analysed using stepwise multiple regression. Results: In the 6-month postpartum period, the level of fatigue was highest at 1 month and significantly decreased from 1-4 months postpartum. Primiparas showed a significantly higher level of fatigue than multiparas during hospital stay and their levels of fatigue more closely approximated the 1-month peak. Multiparas showed significantly higher levels of fatigue than younger primiparas at 6-month postpartum. Factors associated with maternal fatigue included satisfaction with sleep, concerns about child-rearing, satisfaction with social support, financial burden and meal times per day. PMID- 29599995 TI - Surgery nurses' telephone communication: a mixed methods study with a special focus on newcomers' calls. AB - Aims: The aim of this study was (i) to document the main features of surgery nurses' telephone calls, with a special focus on newcomers' calls; and (ii) to identify the main activities accomplished during the newcomers' calls. Design: Mixed methods study. Methods: We audio recorded telephone calls internal to the hospital in two surgery nursing stations. We performed statistical descriptive analysis of the total collection of calls and of those specifically involving the newcomers and compared both sets. We also performed conversation analysis-based coding of the main activities accomplished during newcomers' calls. Results: Surgery nurses' telephone calls are extremely brief, predominantly nurse initiated and take place with a wide range of interlocutors who, for the most part, use mobile phones. The newcomers' calls are only slightly longer, take place with a more limited, but still wide, range of interlocutors and are even more often nurse initiated. The main activities of newcomers' calls are requests and activities related to connecting relevant interlocutors.

AB - Aim: The study aims to describe the establishment of a culturally specific nursing home for Finnish-speaking older persons in Sweden. Design: A descriptive qualitative study. Methods: A descriptive case study based on a review of 14 public documents and individual interviews with two experts in the area, analysed with qualitative content analysis. Results: This study found that shared language, preservation of customs and habits and collaboration between the representatives of the municipality, Finnish-speaking migrant associations and staff at the nursing home influenced the development of the culturally specific nursing home for older Finnish-speaking people intended to avoid loneliness, isolation and misunderstandings among older Finnish-speaking. Collaboration between healthcare service for older persons and minority people resulted in an optimal culturally specific nursing home, simultaneously encountering the majority culture. Nursing and healthcare services need to be aware of positive effects of collaboration with stakeholders to achieve optimal culturally specific nursing homes.

AB - Aim: The aim of this study was to explore first-line nurse managers' perceptions of the challenges involved in decision-making concerning older patients who wish to die. Design: A descriptive qualitative design in three communities in Norway between January 2016 and June 2016. Methods: Qualitative focus group interviews with eight first-line nurse managers. Results: One main theme and two themes were identified: Struggling to make the right decision, The challenge of social isolation and loneliness and When life becomes too painful and problematic. The sub-themes revealed that: Arranging social meeting places where the older patients can talk to other older people is crucial. The participants explained that it was not an easy task to gain an overview of the older patients situation. The right decision could be encouraging the patients to talk about their problems by giving them more time, thereby showing that somebody cares about them. PMID- 29599998 TI - Patients' complaints regarding healthcare encounters and communication. AB - Aim: To explore patient-reported complaints regarding communication and healthcare encounters and how these were responded to by healthcare professionals. Design: A retrospective and descriptive design was used in a County Council in northern part of Sweden. Both quantitative and qualitative methods were used. Methods: The content of 587 patient-reported complaints was included in the study. Descriptive statistical analysis and a deductive content analysis were used to investigate the content in the patient-reported complaints. Results: The results show that patients' dissatisfaction with encounters and communication concerned all departments in the healthcare organization. Patients were most dissatisfied when they were not met in a professional manner. There were differences between genders, where women reported more complaints regarding their dissatisfaction with encounters and communication compared with men. Many of the answers on the patient-reported complaints lack a personal apology and some of the patients failed to receive an answer to their complaints.

AB - Clinicians have historically been integral in innovating and developing technology in medicine and surgery. In recent years, however, in an increasingly complex healthcare system, a doctor with innovative ideas is often left behind. Transition from idea to bedside now entails significant hurdles, which often go unrecognised at the outset, particularly for first-time innovators. The BioInnnovate Ireland process, based on the Stanford Biodesign Programme (Identify, Invent and Implement), aims to streamline the process of innovation within the MedTech sector. These programmes focus on needs-based innovation and enable multidisciplinary teams to innovate and collaborate more succinctly. In this preliminary study, the authors aimed to examine the impact of BioInnovate Ireland has had on the clinicians involved and validate the collaborative process. To date, 13 fellows with backgrounds in clinical medicine have participated in the BioInnovate programme. Ten of these clinicians remain involved in clinical innovation projects with four of these working on Enterprise Ireland funded commercialisation grants and one working as chief executive officer of a service-led start-up, Strive. Of these, five also remain engaged in clinical practice on a full or part-time basis. The clinicians who have returned to full-time clinical practice have used the process and learning of the programme to influence their individual clinical areas and actively seek innovative solutions to meet clinical challenges. Clinicians, in particular, describe gaining value from the BioInnovate programme in areas of 'Understanding Entrepreneurship' and 'Business Strategy'. Further study is needed into the quantitative impact on the ecosystem and impact to other stakeholders. PMID- 29600000 TI - Service user reflections on the impact of involvement in research. AB - Plain English summary: Public involvement can impact on research, on the public who give advice, on the researchers and the research participants. Evaluating impact is an important part of the research process. Two members of a hospital based patient research panel and our coordinator have written this paper. Our panel covers a range of rehabilitation and palliative services. These services form the "Therapeutics and Palliative Care Directorate". We describe how we worked collaboratively with hospital staff and co-produced questionnaires to evaluate the impact of our involvement. We compared the different perspectives of the researchers and panel members on our contribution to the research. We present evidence from these different standpoints, including how our panel made a difference. We found we needed to adapt how we collected the views of the researchers and our members to ensure it was meaningful to our group whilst delivering the wider objective of the hospital. A key finding has been how our involvement has extended into other groups, which has identified opportunities for sharing resources and experience, including areas such as cost effectiveness. Our two-person membership of a high level Board of Academics and Senior Clinicians, which oversees the research we contribute to, has resulted in our opinions influencing the heart of the Directorate's research strategy. We have learned the importance of a flexible approach as the Directorate changes, and the demands on us grow. This will continue to help us share our own development, successes and experience and extend the benefits from working this way. Abstract: Background Reports about the impact of patient and public involvement in research can be improved by involving patients and research staff more collaboratively to co-produce instruments to measure their involvement. This commentary, written by two members of a hospital-based patient panel and their coordinator for its work, describes how we co-produced instruments to evaluate the impact and effectiveness of our involvement. We present here the results, including our quantitative and qualitative findings, of this patient led evaluation and reflect on how our involvement has made a difference to the research projects and research infrastructure within the hospital in which we operate and on us as a panel. Methods Existing impact frameworks and guidelines were reviewed. Members co produced and piloted qualitative questionnaires to identify values associated with patient and public involvement (PPI) from both a researcher and panel member perspective, and collected quantitative metrics to provide descriptive statistics on the type of involvement and activities. Members also produced a comments slip to provide contemporaneous feedback after each meeting. Results The panel has reviewed 36 research projects for the Therapeutics and Palliative Care Directorate drawn from speech and language therapy, physiotherapy, occupational therapy, dietetics, podiatry, palliative care services and chaplaincy. Some of the main results of our involvement have been the development of grant applications and making written information more understandable for research participants. Examples of how the Panel made a difference included providing an effective forum for debate by providing practical suggestions to improve research design and identifying potential issues that may not have occurred to the researcher. The panel has had an impact outside of meetings both within the context in which it operates and on the individuals involved. Examples included: influencing the Directorate research agenda, sharing resources with other groups, developing research relationships, and enabling member participation in different roles and settings. Discussion Embedding ourselves within the Directorate research infrastructure has enabled us to adapt to organisational change and actively contribute to the research strategy. There is greater scope for involvement in areas of cost effectiveness and economic evaluation. Increasing member contributions and networking with other groups provides added value as well as cross fertilisation of ideas as part of our widening impact. Conclusion Evaluating the impact of our involvement has improved our understanding of what aspects of involvement work best for the panel and the researchers who attend our meetings, and in the different settings that we work in. It has helped us to focus on how we need to develop to maximise our resources going forward.

AB - Introduction: Cerebral ischaemia-induced depression is among the most frequent neuropsychiatric consequences and adversely impact the prognosis and recovery of patients. Although several brain regions have been implied in the development of ischaemia-induced depression, the brain region-specific neural cell apoptosis pathways have not been clarified yet. Methods: In this study, bilateral internal carotid artery occlusion (BICAO) mouse model was established to induce cerebral ischaemia. Sucrose preference, tail suspension and forced swim tests were conducted on mice at 7, 21 and 30 days after BICAO treatment. In addition, brain regional ischaemic neuron loss was investigated by using immunofluorescent staining of neuronal nuclei (NeuN) and caspase-8/-9-dependent cell apoptosis was also examined by western blot analysis. Results: BICAO-induced cerebral ischaemia resulted in decreased sucrose preference and increased immobility times, which were representative depressive-like behaviours of mice until 30 days after BICAO treatment compared with Sham-operated mice. This outcome was associated with significant neuron loss by using immunofluorescent staining and increased cleavage levels of pro-caspase-3/-8/-9, but not pro-caspase-12, by western blot analysis in hypothalamus, midbrain, prefrontal cortex and hippocampus of mice. Conclusions: This study showed that BICAO-induced ischaemia caused depressive like behaviours and caspase-8/-9-dependent neural cell apoptosis in several brain regions, including hypothalamus and midbrain of mice. PMID- 29600002 TI - Prestroke selective serotonin reuptake inhibitor use and functional outcomes after ischaemic stroke. AB - Background: Selective serotonin reuptake inhibitors (SSRIs) have been implicated in contributing to recovery after acute ischaemic stroke. In particular, poststroke initiation of an SSRI has been demonstrated to improve motor recovery. The role of prestroke SSRI use on functional outcomes and stroke recovery is less clear. We aimed to examine the effect of prestroke SSRI use on metrics of hospitalisation and functional recovery. Methods: We included 4968 consecutive patients from January 2006 to June 2015 in our local Get With The Guidelines Stroke registry in whom a preadmission drug list could be extracted from an administrative research data registry. Univariate and multivariate analyses were performed to identify predictors of functional outcomes. Results: On univariate analysis, among 4698 ischaemic strokes (740 SSRI users and 3948 non-users), SSRI use before acute ischaemic stroke did not impact the National Institutes of Health Stroke Scale (NIHSS) admission score, length of stay or rate of symptomatic haemorrhage. Patients using SSRIs prior to their stroke were more likely to present with weakness (57% vs 47.3%; P<0.001) and have hospitalisations complicated by pneumonia (7.6% vs 5.7%; P<0.001). Moreover, prestroke SSRI use was associated with a negative impact on ambulatory status at discharge and discharge to home. On multivariate regression analysis, SSRI use was associated with lower likelihood of discharge to home (adjusted OR 0.79, 95% CI 0.62 to 0.997, P<0.05). Conclusions: SSRI use preceding an acute ischaemic stroke is associated with lower rates of discharge to home despite no significant increase in length of stay or NIHSS score. PMID- 29600003 TI - Endovascular revascularisation of acute tandem vertebrobasilar artery occlusion: seven case series with literature reviews. AB - Background: The outcome of acute ischaemic stroke due to tandem vertebrobasilar artery occlusion was poor. Endovascular revascularisation may be a positive approach for acute basilar artery occlusion combined with vertebral ostium stenosis or occlusion. We reported seven patients with acute vertebrobasilar tandem occlusion by using angioplasty or stenting for proximal lesion and thrombectomy for distal occlusion. Materials and methods: Consecutive patients with acute tandem vertebrobasilar artery occlusion at two centres were included in this study. We retrospectively analysed the clinical, technical and functional outcomes of the patients. Results: From March 2016 to March 2017, seven patients were included. The mean age and National Institute of Health Stroke Scale score at admission was 57 years and 22, respectively. A reverse approach was used in five patients. The Thrombolysis in Cerebral Infarction score 2b-3 was acquired in all patients. There were no procedural complications. The modified Rankin Scale score was 1-2 for three patients and 4 for one patient at 3 months. Three patients died at 3 months of follow-up. Conclusions: Endovascular revascularisation may be feasible for acute tandem vertebrobasilar artery occlusion, and more researches are needed. PMID- 29600004 TI - Efficacy and safety of intravenous recombinant tissue plasminogen activator in mild ischaemic stroke: a meta-analysis. AB - The benefits and safety of intravenous recombinant tissue plasminogen activator (IV-tPA) for patients with mild ischaemic stroke (MIS) are still unclear. The objective of this meta-analysis was to evaluate the efficacy and safety of IV-tPA as treatment for patients with MIS. We performed a systematic literature search across MEDLINE, Embase, Central, Global Health and Cumulative Index to Nursing and Allied Health Literature (CINAHL), from inception to 10 November 2016, to identify all related studies. Where possible, data were pooled for meta-analysis with odds ratio (OR) and corresponding 95% confidence interval (CI) using the fixed-effects model. MIS was defined as having National Institutes of Health Stroke Scale score of <=6. We included seven studies with a total of 1591 patients based on the prespecified inclusion and exclusion criteria. The meta analysis indicated a high odds of excellent functional outcome based on the modified Rankin Scale or Oxfordshire Handicap Score 0-1 (OR=1.43; 95% CI 1.14 to 1.79; P=0.002, I2=35%) in patients treated with IV-tPA compared with those not treated with IV-tPA (74.8% vs 67.6%). There was a high risk of symptomatic intracranial haemorrhage (sICH) with IV-tPA treatment (OR=10.13; 95% CI 1.93 to 53.02; P=0.006, I2=0%) (1.9% vs 0.0%) but not mortality (OR=0.78; 95% CI 0.43 to 1.43; P=0.43, I2=0%) (2.4% vs 2.9%). Treatment with IV-tPA was associated with better functional outcome but not mortality among patients with MIS, although there was an increased risk of sICH. Randomised trials are warranted to confirm these findings. PMID- 29600005 TI - Current status of intravenous tissue plasminogen activator dosage for acute ischaemic stroke: an updated systematic review. AB - The optimal dose of recombinant tissue plasminogen activator (rtPA) for acute ischaemic stroke (AIS) remains controversial, especially in Asian countries. We aimed to update the evidence regarding the use of low-dose versus standard-dose rtPA. We performed a systematic literature search across MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from inception to 22 August 2016 to identify all related studies. The outcomes were death or disability (defined by modified Rankin Scale 2-6), death, and symptomatic intracerebral haemorrhage (sICH). Where possible, data were pooled for meta analysis with ORs and corresponding 95% CIs by means of random-effects or fixed effects meta-analysis. We included 26 observational studies and 1 randomised controlled trial with a total of 23 210 patients. Variable doses of rtPA were used for thrombolysis of AIS in Asia. Meta-analysis shows that low-dose rtPA was not associated with increased risk of death or disability (OR 1.13, 95% CI 0.95 to 1.33), or death (OR 0.86, 95% CI 0.74 to 1.01), or decreased risk of sICH (OR 1.06, 95% CI 0.65 to 1.72). The results remained consistent when sensitivity analyses were performed including only low-dose and standard-dose rtPA or only Asian studies. Our review shows small difference between the outcomes or the risk profile in the studies using low-dose and/or standard-dose rtPA for AIS. Low-dose rtPA was not associated with lower risk of death or disability, death alone, or sICH.

AB - Infections occur commonly after stroke and are strongly associated with an unfavourable functional outcome of these patients. Approaches for effective management of poststroke infection remain scarce, presenting an urgent need for preventive anti-infection strategies for patients who have suffered a stroke. Emerging evidence indicates that stroke impairs systemic immune responses and increases the susceptibility to infections, suggesting that the modification of impaired immune defence could be beneficial. In this review, we summarised previous attempts to prevent poststroke infections using prophylactic antibiotics and the current understanding of stroke-induced immunosuppression. Further elucidation of the immune mechanisms of stroke will pave the way to tailored design of new treatment to combat poststroke infection via modifying the immune system.

Esophageal squamous cell carcinoma (ESCC) is the predominant subtype in China. The tumorigenesis mechanism in ESCC is unclear. The aim of this study was to identify key transcription factors (TFs) in ESCC and elucidate the mechanism of it. Methods: A total of ten published microarray datasets of ESCC was downloaded from the Gene Expression Omnibus (GEO). Then, bioinformatics analyses including differentially expressed genes (DEGs) analysis, gene ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, TFs-genes regulatory network construction was performed. Quantitative real-time polymerase chain reactions (qRT-PCR) were used to detect the expression levels of TFs and DEGs in ESCC. The association between stage and TFs and the association between survival and TFs were evaluated based on The Cancer Genome Atlas (TCGA), respectively. Results: A total of 1,248 dysregulated genes were selected as DEGs in ESCC. A total of 26 TFs and corresponding target-genes were identified. The ESCC-specific transcriptional regulatory network was constructed. The network was consisted of 882 edges and 631 nodes. BRCA1, SOX10, ARID3A, ZNF354C and NFIC had the highest connectivity with DEGs, and regulated 92, 89, 82, 79 and 78 DEGs in the network, respectively. All these 1,248 DEGs were significantly enriched in cell cycle, DNA replication and oocyte meiosis pathways. The qRT-PCR results were consistent with our microarray analysis. High expression of SREBF1 and TFAP2A were significantly correlated with the longer overall survival time of patients with ESCC. Conclusions: BRCA1, SOX10, ARID3A, ZNF354C and NFIC might be the key TFs in carcinogenesis and development of ESCC by regulating their corresponding target-genes involved in cell cycle, DNA replication and oocyte meiosis pathways. SREBF1 and TFAP2A may be two potential prognostic biomarkers of ESCC. PMID- 29600045 TI - Validation of the T descriptor in the new 8th TNM classification for non-small cell lung cancer. AB - Background: To validate new proposals for the revision of T descriptors and to compare the prognostic value of the seventh and forthcoming eighth edition of the tumor, node and metastasis (TNM) classification for lung cancer. Methods: A retrospective analysis was conducted of 1,316 patients with non-small lung cancer who underwent pulmonary resection between 1999 and 2012. Patients who had a positive nodal status or distant metastasis were excluded. We classified these patients according to the seventh and eighth edition of the TNM system, and analyzed differences in stage specific survival. Harrell's concordance (C)-index and Heagerty's integrated area under the curve (iAUC) were used to assess the overall predictive ability of the different TNM versions. Results: There were no significant survival differences between each stage based on the T stage criteria of the eighth edition, most notably between T1a and T1b (P=0.752), and T1c, T2a, and T2b (P=0.832). The C-indices of the classification based on the seventh and eighth edition were 0.681 and 0.675, respectively. There was no significant difference in the C-indices between the seventh and eighth edition. The iAUC value for overall survival of the seventh and eighth staging editions was 0.637 and 0.631, respectively. The differences in iAUC between the seventh and eighth editions were also not statistically significant. Conclusions: The newly proposed T descriptors in the eighth TNM classification system did not allow a more accurate prediction of prognosis compared with the current seventh edition in our population. PMID- 29600046 TI - Bronchoalveolar lavage fluid microbiota dysbiosis in infants with protracted bacterial bronchitis. AB - Background: Protracted bacterial bronchitis (PBB) is a chronic purulent bronchitis which could cause recurrent coughing and wheezing in infants. Based on previous reports, main pathogens which caused PBB were identified in the patients, but their impacts on lung microbiota dysbiosis remain unclear. Methods: In this study, bronchoalveolar lavage fluid (BALF) was collected from PBB infants and tracheomalacia (TM) infants younger than 3 years old under the instruction of Shenzhen Children's Hospital, and 12 samples were randomly selected for 16S rDNA analysis in each group. Based on the results of bacterial composition, the microbiota diversity and co-occurrence network in PBB and TM group were detected and compared. Results: Microbiota diversity was significantly lower in PBB group than it in TM group (P<0.001 for the comparison of Shannon and Simpson indexes). The PBB group was found to harbor 25 accumulated bacterial agents by comparison with TM group, including Haemophilus (P<0.001) and Bacteroides (P<0.001). Whilst, the populations of Lactococcus (P<0.001) and Lactobacillus (P<0.001) were dramatically smaller in PBB group. The co-occurrence network in PBB group also differed from that of TM group. It contained four core nodes in PBB patients, including Haemophilus, Parabacteroides, Porphyromonas, and Cronobacter. Haemophilus was found to be negatively associated with most counterparts, including Clostridium and Bacillus. Conclusions: PBB infants contained discrepant lung genera and co-occurrence network when compared with TM infants. This retrospective study may deepen our understanding of PBB pathogenesis, and it also provided a foundation for bacterial adjunctive therapy of infantile PBB in accordance with clinical treatment. PMID- 29600047 TI - Evaluation of the 95% limits of agreement of the volumes of 5-year clinically stable solid nodules for the development of a follow-up system for indeterminate solid nodules in CT lung cancer screening. AB - Background: This study sought to evaluate the 95% limits of agreement of the volumes of 5-year clinically stable solid nodules for the development of a follow up system for indeterminate solid nodules. Methods: The volumes of 226 solid nodules that had been clinically stable for 5 years were measured in 186 patients (53 female never-smokers, 36 male never-smokers, 51 males with <30 pack-years, and 46 males with >=30 pack-years) using a three-dimensional semiautomated method. Volume changes were evaluated using three methods: percent change, proportional change and growth rate. The 95% limits of agreement were evaluated using the Bland-Altman method. Results: The 95% limits of agreement were as follows: range of percent change, from +/-34.5% to +/-37.8%; range of proportional change, from +/-34.1% to +/-36.8%; and range of growth rate, from +/ 39.2% to +/-47.4%. Percent change-based, proportional change-based, and growth rate-based diagnoses of an increase or decrease in ten solid nodules were made at a mean of 302+/-402, 367+/-455, and 329+/-496 days, respectively, compared with a clinical diagnosis made at 809+/-616 days (P<0.05). Conclusions: The 95% limits of agreement for volume change in 5-year stable solid nodules may enable the detection of an increase or decrease in the solid nodule at an earlier stage than that enabled by a clinical diagnosis, possibly contributing to the development of a follow-up system for reducing the number of additional Computed tomography (CT) scans performed during the follow-up period. PMID- 29600048 TI - Correlation of bispectral index and Richmond agitation sedation scale for evaluating sedation depth: a retrospective study. AB - Background: This study aims to verify the correlation of bispectral index (BIS) and Richmond agitation sedation scale (RASS) for evaluating these and explore possibility of replacing RASS with BIS. Methods: This retrospective cohort study consisted of 74 patients who were collected from the third Intensive Care Unit (ICU) ward of XXX Hospital between May 2012 and June 2015 in this retrospective study. Sedation levels were evaluated using the 10-grade RASS and were continuously monitored with a BIS monitor during the procedure every 5 minutes. BIS values and RASS scores were recorded. Results: Patients were divided into dexmedetomidine (n=31) and midazolam (n=43) groups, and 342 paired data were collected. A statistically significant correlation existed between BIS values and RASS scores either in all patients undergoing flexible fiberoptic bronchoscopy (FFB) or in dexmedetomidine and midazolam groups at different time points. Correlation coefficient was higher in midazolam group compared with dexmedetomidine group at different time points (P<0.05). Conclusions: A correlation was observed between BIS and RASS for evaluating depth of sedation in ICU patients undergoing FFB (P<0.05). Study results indicated that BIS monitoring is a meaningful tool, which can be applied as an adjunctive and alternative method to assess sedation, especially for high-risk patients who are prone to be under- or over-sedation. PMID- 29600049 TI - Three-dimensional computed tomography reconstruction for operative planning in robotic segmentectomy: a pilot study. AB - Background: The objective of our pilot study was to assess if three-dimensional (3D) reconstruction performed by Visible PatientTM could be helpful for the operative planning, efficiency and safety of robot-assisted segmentectomy. Methods: Between 2014 and 2015, 3D reconstructions were provided by the Visible PatientTM online service and used for the operative planning of robotic segmentectomy. To obtain 3D reconstruction, the surgeon uploaded the anonymized computed tomography (CT) image of the patient to the secured Visible PatientTM server and then downloaded the model after completion. Results: Nine segmentectomies were performed between 2014 and 2015 using a pre-operative 3D model. All 3D reconstructions met our expectations: anatomical accuracy (bronchi, arteries, veins, tumor, and the thoracic wall with intercostal spaces), accurate delimitation of each segment in the lobe of interest, margin resection, free space rotation, portability (smartphone, tablet) and time saving technique. Conclusions: We have shown that operative planning by 3D CT using Visible PatientTM reconstruction is useful in our practice of robot-assisted segmentectomy. The main disadvantage is the high cost. Its impact on reducing complications and improving surgical efficiency is the object of an ongoing study. PMID- 29600050 TI - PTEN gene silencing contributes to airway remodeling and induces airway smooth muscle cell proliferation in mice with allergic asthma. AB - Background: Allergic asthma is a complex genetic disorder that involves interactions between genetic and environmental factors. Usage of PTEN may be a good therapeutic strategy for the management of allergic inflammation. Thus, the present study aims to explore the effects of phosphatase and tensin homolog (PTEN) gene silencing on airway remodeling and proliferation of airway smooth muscle cells (ASMCs) in a mouse model of allergic asthma. Methods: A total of 56 healthy female BABL/c mice (weighing between 16 to 22 grams) were selected and were assigned on random into ovalbumin (OVA; mice were stimulated with OVA to induce allergic asthma), OVA + si-PTEN, normal saline (NS; mice were treated with normal saline) and NS + si-PTEN groups. Masson staining was employed in order to observe lung tissue sections. Immunohistochemical staining was used to detect the expression of alpha-SMA+. Gene silencing was conducted in the NS + si-PTEN and OVA + si-PTEN groups. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blotting were used to detect the mRNA and protein expressions of PTEN in ASMCs of each group. CCK-8 assay and flow cytometry were performed to determine the cell proliferation rate and cell cycle. Results: Airway remodeling and changes of smooth muscle layer were found in allergic asthmatic mice with thick airway walls. The expression of alpha smooth muscle actin (alpha-SMA+) was significantly higher in ASMCs of the OVA, OVA + si-PTEN and NS + si-PTEN groups compared with ASMCs of the NS group. The mRNA and protein expressions of PTEN reduced in the OVA, OVA + si-PTEN and NS + si-PTEN groups. The rate of ASMCs proliferation in OVA, OVA + si-PTEN and NS + si-PTEN groups were significantly higher than the NS group. The proportion of ASMCs in S and G2 stages increased, while the number of cells in the G1 stage decreased after PTEN gene silencing. Conclusions: These results demonstrated that PTEN gene silencing might promote proliferation of ASMCs and airway remodeling in a mouse model of allergic asthma. PMID- 29600051 TI - In vitro effects of N-acetylcysteine alone and combined with tigecycline on planktonic cells and biofilms of Acinetobacter baumannii. AB - Background: Acinetobacter baumannii (A. baumannii), as a common opportunistic pathogen, has strong ability to form biofilms, which has led to drug resistance and chronic infections. The combination of N-acetylcysteine (NAC) and tigecycline (TGC) was demonstrated to synergistically inhibit biofilm-associated bacterial infections, including methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis. The purpose of this study is to investigate the effect of NAC and TGC on planktonic cells and biofilms of A. baumannii. Methods: Minimum inhibitory concentrations (MICs) of NAC were determined by broth microdilution method. Biofilm susceptibility was assessed by crystal violet stain. Interactive effects of NAC and TGC on planktonic cells were determined by checkerboard MIC assay. Viable cell count was used to evaluate the combined effect of NAC and TGC on biofilm-embedded bacteria. Results: MICs of NAC against 25 A. baumannii isolates ranged from 16 to 128 mg/mL. NAC alone (0.5-128 mg/mL) significantly inhibited biofilm formation and disrupted preformed biofilms. The combination of NAC and TGC induced a partial synergistic effect (60%) and additive effect (28%) on planktonic bacteria. For biofilm-embedded bacteria, treatment with 16 mg/mL NAC alone or 2 ug/mL TGC alone resulted in significant bactericidal effects (P<0.01 and P<0.05, respectively); synergistic bactericidal effect was found at 4 mg/mL NAC combined with 0.5 ug/mL TGC (P<0.01). Conclusions: NAC alone significantly inhibited biofilm formation of A. baumannii. The combination of NAC and TGC induced partial synergistic effect against planktonic cells and synergistic effect against biofilm-embedded A. baumannii, which might be a therapeutic option for biofilm-related infections of A. baumannii. PMID- 29600052 TI - A pooled analysis of advanced nonsquamous non-small cell lung cancer patients with stable treated brain metastases in two phase II trials receiving bevacizumab and pemetrexed as second-line therapy. AB - Background: Brain metastases are a common complication of advanced non-small cell lung cancer (NSCLC). Patients with brain metastases were excluded from the registration trials of bevacizumab that showed a survival benefit with the use of angiogenesis inhibition. Methods: In this study, we pooled data from two separate trials designed to evaluate the risk of central nervous system (CNS) hemorrhage in patients with stable treated brain metastases to look specifically at both the safety and efficacy of bevacizumab and pemetrexed when used as second-line treatment in NSCLC patients with stable treated brain metastases. Results: We report acceptable safety and promising efficacy from our analysis. Conclusions: Our study adds further evidence of safety of administering pemetrexed and bevacizumab to patients with stable brain metastases. There is increasing roles for systemic therapies to treat stable brain metastases for patients with advanced NSCLC. PMID- 29600053 TI - Long-term quality of life after endovac-therapy in anastomotic leakages after esophagectomy. AB - Background: Endoluminal vacuum therapy (EVT) has been successfully established with promising survival rates in the treatment of anastomotic leakages after esophagectomy. It is still unclear how this therapy affects health related quality of life (HRQOL). Methods: HRQOL was prospectively assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) questionnaire. Assessment was carried out prior to surgery, after discharge, 6 months and 12 months after surgery. We compared HRQOL after EVT (n=23) to patients without anastomotic leakages as a control group (n=50). Investigated parameters included age, sex, and localization of anastomosis, number of EVT sessions, length of ICU and hospital stay, therapy failure, anastomotic stricture, tumour stage, neoadjuvant and adjuvant treatment, sepsis. Results: After esophagectomy HRQOL increased within 12 months. Compared to patients without leakages the EVT-group showed significantly better HRQOL scores for pain, social and emotional functioning after discharge and 6 months after surgery. In the long-term follow up HRQOL was comparable between the groups. After EVT age, advanced tumour stage, tumour recurrence, anastomotic strictures, length of ICU and hospital stay and length of EVT had a significant influence on HRQOL. Conclusions: EVT is a promising therapeutic option in leakages after esophagectomy. In the long-term, HRQOL of EVT-treated patients is comparable to patients, who did not suffer from postsurgical leakages. PMID- 29600054 TI - Manual aspiration in the biopsy-side down position to deal with delayed pneumothorax after lung biopsy. AB - Background: To assess the effect of aspiration in the biopsy-side down position to deal with delayed pneumothorax after computed tomography (CT)-guided lung biopsy. Methods: A retrospective review was performed of the 236 delayed pneumothorax patients who underwent CT-guided transthoracic needle biopsies (TTNBs). Asymptomatic minimal pneumothorax patients were managed conservatively. Manual aspirations were applied for symptomatic cases with minimal pneumothorax and all cases with moderate to large pneumothorax. Patients were included into two groups: in group A (35 patients), aspiration was performed in the same position as the biopsy, while in group B (54 patients), patients were turned to the biopsy-side down position (from supine to prone or vice versa), and aspiration was conducted. The efficacy of two approaches was evaluated. Results: One hundred forty-seven (62.3%) asymptomatic cases resolved without treatment. Distance between parietal and visceral pleura before and after aspiration were 4.24+/-1.87 and 1.93+/-2.33 cm for group A, 3.92+/-1.31 and 0.98+/-1.50 cm for group B, respectively. Volume of aspirated air in group A and group B were 735.4+/-231.8 and 434.8+/-320.3 mL, respectively. Complete lung expansion was detected in 28.6% (10/35) and 38.9% (21/54) for group A and group B, respectively. The overall effective rate and failure rate were 74.3% (26/35) and 25.7%(9/35) for group A, 92.6% (50/54) and 7.4%((4/54))for group B, respectively, which have significant statistic difference (P<0.05). Conclusions: Manual aspiration in biopsy-side down position demonstrates the safety and efficacy in treating delayed pneumothorax after CT-guided TTNBs. Thus reduce the rate of pneumothorax requiring drainage catheter placement. PMID- 29600055 TI - Clarithromycin mitigates radiation pneumonitis in patients with lung cancer treated with stereotactic body radiotherapy. AB - Background: Radiation pneumonitis is a critical pulmonary toxicity after irradiation of the lung. Macrolides including clarithromycin (CAM) are antibiotics. They also have immunomodulatory properties and are used to treat respiratory inflammatory diseases. Radiation pneumonitis has similar pathology to them. Adverse reactions to macrolides are few and self-limited. We thus administered CAM to patients with high-risk factors for radiation pneumonitis, and retrospectively investigated whether CAM mitigated radiation pneumonitis following stereotactic body radiotherapy (SBRT). Methods: Among consecutive patients treated with SBRT, we retrospectively examined lung cancer patients treated with a total dose of 40-60 Gy in 5-10 fractions and followed >=6 months. Since January 2014, CAM has been administered in patients with pretreatment predictable radiation pneumonitis high-risk factors, including idiopathic interstitial pneumonias (IIPs), and elevated Krebs von den Lungen-6 (KL-6) and/or surfactant protein D (SP-D), and in patients developing early onset radiation pneumonitis. Results: Five hundred and eighty eligible patients were identified and divided into 445 patients during the non-CAM-administration era (non-CAM-era) (before December 2013) and 136 patients during the CAM-administration era (CAM era) (after January 2014). Median follow-up durations were 38.0 and 13.9 months, respectively. The rates of radiation pneumonitis >= grade 2 and >= grade 3 were significantly lower in CAM-era (grade >=2, 16% vs. 9.6%, P=0.047; grade >=3, 3.8% vs. 0.73%, P=0.037). For patients with the pretreatment predictable high-risk factors, the rate of radiation pneumonitis >= grade 3 was significantly lower, and that of grade >=2 had a lower tendency (grade >=3, 7.2% vs. 0%, P=0.011; grade >=2, 21% vs. 9.6%, P=0.061). For patients developing early onset radiation pneumonitis, the rate of radiation pneumonitis >= grade 3 was also significantly lower (23% vs. 0%, P<0.05). Multivariate analysis revealed that dose-volumetric factor, the pretreatment predictable high-risk factors and non-CAM-administration era were significantly associated with or trended toward radiation pneumonitis >= grade 2 and >= grade 3. Conclusions: CAM mitigated radiation pneumonitis following SBRT. The efficacy of CAM should be confirmed in prospective studies. PMID- 29600056 TI - Pulmonary embolism concurrent with lung cancer and central emboli predict mortality in patients with lung cancer and pulmonary embolism. AB - Background: Patients with lung cancer commonly experience pulmonary embolism (PE). The aim of the present study was to examine the clinical features of patients with lung cancer and PE and to investigate prognostic factors in these patients. Methods: This retrospective study divided patients with lung cancer and PE into a group of patients with PE diagnosed concomitantly with lung cancer (concurrent group) and a group with PE detected after lung cancer (sequential group), compared the clinical characteristics of patients in the two groups, and investigated prognostic factors in these patients. Results: The study population consisted of the concurrent group [27 patients (10.1%)] and the sequential group [240 patients (89.9%)]. The concurrent group exhibited higher percentages of stage I cancer at the diagnosis of PE [6 (22.2%) vs. 8 (3.3%), P<0.001] and right ventricular (RV) dilation on computed tomography (CT) [14 (51.9%) vs. 41 (17.1%), P<0.001], as well as lower rate of small cell carcinoma [1 (3.7%) vs. 49 (20.4%), P=0.036] than the sequential group. PE concurrent with lung cancer [hazard ratio (HR) =2.64, 95% confidence interval (CI): 1.57-4.43, P<0.001] and central PE (HR =1.46, 95% CI: 1.02-2.10, P=0.04) were independent predictors of mortality in patients with lung cancer and PE. Conclusions: PE concurrent with lung cancer is characterized by more severe PE and infrequent small cell carcinoma. PE concurrent with lung cancer and central emboli may be independent prognostic factors in patients with lung cancer and PE. PMID- 29600057 TI - Neutrophil-to-lymphocyte ratio as a prognostic marker in acute respiratory distress syndrome patients: a retrospective study. AB - Background: Acute respiratory distress syndrome (ARDS) is the leading cause of high mortality in intensive care units (ICUs) worldwide. An effective marker for prognosis in ARDS is particularly important given the absence of effective treatment strategies aside from small tidal volume ventilation. Previous studies identified an association between the neutrophil-to-lymphocyte ratio (NLR) and prognosis in critical patients. In this study, we explored the prognostic and predictive value of the NLR in ARDS patients. Methods: We retrospectively included 275 ARDS patients treated at a single institute from 2008 to 2015. After excluding patients with chronic lung disease, acute myocardial infarction and missing data, 247 patients were ultimately included in the analysis. Clinical characteristics and experimental test data, including the NLR, were collected from medical records at 24 hours after the ARDS diagnosis. Independent prognostic factors were determined by multivariate Cox regression analysis. Subgroup stratification was performed according to different factors, and the continuous factors were divided according to the median values. Results: The NLR in survivors was significantly lower than that in non-survivors (P<0.001). We took the median NLR value as the cut-off point and further divided all patients into a high NLR group (NLR >14) and a low NLR group (NLR <=14). We found that an NLR >14 was associated with a shorter overall survival (OS) (P=0.005). In the multivariate Cox regression model, we further identified an NLR >14 as an independent prognostic factor for OS [hazard ratio (HR) 1.532, (95% CI, 1.095 2.143), P=0.013]. Subgroup analysis showed that the prognostic value of the NLR was higher in hypertensive patients (P=0.009) and in patients with low red blood cell specific volume (P=0.013), high sodium (P=0.002) and high creatinine levels (P=0.017). Conclusions: The NLR is potentially a predictive prognostic biomarker in ARDS patients. PMID- 29600058 TI - Assessment of the mitral valve coaptation zone with 2D and 3D transesophageal echocardiography before and after mitral valve repair. AB - Background: Mitral valve (MV) coaptation is very important in MV repair patients. But accurate quantitation of the degree of MV coaptation remains challenging. This study aimed to evaluate the utility of two-dimensional (2D) and three dimensional (3D) transesophageal echocardiography (TEE) to assess MV coaptation before and after MV repair. Methods: Forty-eight patients [(age: 52.23+/-13.31 years; 26 men (54.17%)] undergoing MV repair for mitral regurgitation (MR) were studied. We assessed the utility of 2D and 3D TEE to assess MV coaptation before and after MV repair. Complete conventional 2D and 3D TEE studies were performed, and the degree of the MV coaptation defect before and after surgery was assessed by measuring the MV coaptation length (CL) and length index (CLI) with 2D TEE, and the coaptation area (CA) and coaptation area index (CAI) with 3D TEE. Results: CL and CLI were measured successfully in 46 (95.83%) patients and CA and CAI in 39 (81.25%). Compared with preoperatively, postoperative CL, CLI, CA, and CAI were significantly increased (CL: 4.99+/-0.79 to 9.66+/-1.09 mm, P<0.05; CLI: 9.30%+/-2.66% to 38.24%+/-3.82%, P<0.05; CA: 158.49+/-64.17 to 371.33+/-143.57 mm2, P<0.05; CAI: 9.71%+/-2.76% to 36.24%+/-7.26%, P<0.05). Spearman's rank correlation analysis revealed that the CLI and CAI had a significant negative correlation with the degree of MR (r=-0.97, P<0.01; r=-0.92, P<0.01, respectively). Furthermore, Pearson's correlation analysis revealed that the CLI was significantly correlated with the CAI both preoperatively (r=-0.66, P<0.01) and postoperatively (r=-0.67, P<0.01). Conclusions: The coaptation variables increased significantly in patients undergoing MV repair. The CLI and CAI significantly correlated with MR severity. The CL and CLI determined with 2D TEE are more feasible than the CA and CAI determined with 3D TEE. Both 2D and 3D variables may complement each other for aiding MV repair. 2D CLI is an alternative to 3D CAI due to its simplicity. PMID- 29600059 TI - Video-assisted thoracic surgery for thymoma: long-term follow-up results and prognostic factors-single-center experience of 150 cases. AB - Background: The use of video-assisted thoracic surgery (VATS) in the treatment of thymoma is becoming more and more common. The aim of this study was to evaluate safety and effectiveness of thoracoscopic treatment of thymoma and, more importantly, to report long-term follow-up results of a large single-center cohort. Methods: A retrospective review of a prospective database was performed. In total, 150 patients who underwent VATS resection for thymoma at Peking University People's Hospital from April 2001 to November 2014 were retrospectively reviewed. Results: Average operation time was 140.1+/-54.2 min, median blood loss was 50 mL (range, 10-700 mL), median post-operative drainage time was 3 days (range, 1-11 days), and median length of post-op stay was 5 days (range, 2-20 days); 134 patients (89.3%) were followed up successfully. Median follow-up was 59.5 months (range, 2-187 months). Five- and 10-year recurrence free survival (RFS) rates of entire group were 96.5% and 94.4%, respectively; 5- and 10-year RFS rates for Masaoka stages I + II were 98.1% and 98.1%, respectively; 5- and 6-year RFS rates for Masaoka stage III were 90% and 60%, respectively. One case of recurrence in five Masaoka stage IV patients was observed, and 4-year RFS was 80%. Multivariable analysis indicated that recurrence tended to occur in Masaoka stages III + IV patients (P=0.037, HR =12.69, 95% CI: 1.17-138.22) and older patients had a lower risk of recurrence (P=0.029, HR =0.87, 95% CI: 0.77-0.99). Myasthenia gravis (MG) presented in 44 patients (29.3%), of which 36 patients (81.8%) were followed up. Nine patients achieved complete remission, and 19 patients had symptom improvement after surgery. Overall response rate of MG was 77.8% (28/36). Conclusions: VATS was a safe and effective procedure for treatment of thymomas with satisfactory prognosis. MG with thymoma treated by VATS had comparable neurological outcome to that associated with the trans-sternal approach. PMID- 29600060 TI - Positive correlation between postoperative tumor recurrence and changes in circulating tumor cell counts in pulmonary venous blood (pvCTC) during surgical manipulation in non-small cell lung cancer. AB - Background: In non-small cell lung cancer (NSCLC), circulating tumor cells (CTC) are shed and circulate to the peripheral blood through the pulmonary vein. Previously, CTC count in pulmonary venous blood (pvCTC) was shown to significantly increase after surgical manipulation. Therefore, we assessed the correlation between the changes in the pvCTC count (DeltapvCTC) and clinical outcomes. Methods: Consecutive patients with peripheral-type, NSCLC, who underwent lobectomy or bi-lobectomy through open thoracotomy, were enrolled prospectively. Before and after lobectomy, 2.5 mL of blood was drawn from the associated lobar pulmonary vein (PV), and was served for the quantitative evaluation of CTC using the CellSearch(r) system. The cut-off point of DeltapvCTC was determined according to clinical outcomes and DeltapvCTC using receiver operation characteristic (ROC) curve. Then the correlation between DeltapvCTC and clinical outcomes was evaluated by Kaplan-Meier analyses and log-rank test. In addition, the correlation between DeltapvCTC and perioperative variables was assessed. Results: A total of 30 patients were enrolled, tumor recurrence occurred in 11 patients over a median follow-up of 64.4 months. Of these, 7 patients had distant metastasis and 4 had local recurrence. The median DeltapvCTC was 49 cells/2.5 mL, and pvCTC-count was increased during surgical manipulation in 24 patients (80%). We divided patients into two groups based on DeltapvCTC with the cut-off value as 119 cells/2.5 mL according to ROC curve. Significant shorter time to distant metastasis (TDM) (P=0.0123) was observed in high DeltapvCTC group (DeltapvCTC >=119 cells/2.5 mL) than low DeltapvCTC group (DeltapvCTC <119 cells/ 2.5mL). Neither disease-free survival (DFS) nor overall survival (OS) was significantly correlated with DeltapvCTC. Conclusions: Increasing pvCTC count during surgical manipulation was significantly correlated with postoperative distant metastasis in completely resected NSCLC patients. Significant shorter TDM was observed in patient with high DeltapvCTC group. PMID- 29600061 TI - Clinical applications of virtual navigation bronchial intervention. AB - Background: In patients with bronchial tumors, we frequently consider endoscopic treatment as the first treatment of choice. All computed tomography (CT) must satisfy several conditions necessary to analyze images by Synapse Vincent. To select safer and more precise approaches for patients with bronchial tumors, we determined the indications and efficacy of virtual navigation intervention for the treatment of bronchial tumors. Methods: We examined the efficacy of virtual navigation bronchial intervention for the treatment of bronchial tumors located at a variety of sites in the tracheobronchial tree using a high-speed 3 dimensional (3D) image analysis system, Synapse Vincent. Constructed images can be utilized to decide on the simulation and interventional strategy as well as for navigation during interventional manipulation in two cases. Results: Synapse Vincent was used to determine the optimal planning of virtual navigation bronchial intervention. Moreover, this system can detect tumor location and alsodepict surrounding tissues, quickly, accurately, and safely. The feasibility and safety of Synapse Vincent in performing useful preoperative simulation and navigation of surgical procedures can lead to safer, more precise, and less invasion for the patient, and makes it easy to construct an image, depending on the purpose, in 5-10 minutes using Synapse Vincent. Moreover, if the lesion is in the parenchyma or sub-bronchial lumen, it helps to perform simulation with virtual skeletal subtraction to estimate potential lesion movement. By using virtual navigation system for simulation, bronchial intervention was performed with no complications safely and precisely. Conclusions: Preoperative simulation using virtual navigation bronchial intervention reduces the surgeon's stress levels, particularly when highly skilled techniques are needed to operate on lesions. This task, including both preoperative simulation and intraoperative navigation, leads to greater safety and precision. These technological instruments are helpful for bronchial intervention procedures, and are also excellent devices for educational training. PMID- 29600062 TI - Pulmonary metastasectomy in sarcoma-experiences with laser-assisted resection. AB - Background: Previous data suggest a survival benefit in well selected patients with extrathoracic sarcoma after pulmonary metastasectomy. Different techniques have been described for pulmonary metastasectomy; however laser-assisted surgery (LAS) was suggested to provide the best outcome in patients with higher numbers of metastases. Methods: Data were extracted from a prospectively maintained institutional database and a total of 83 patients who underwent pulmonary metastasectomy at our clinic in the last 11 years were identified. Results: We analyzed a total of 106 operations of which LAS was performed in 46 and conventional resection in 60 cases. Significantly more metastases were resected in the LAS group compared to the conventional group [median, interquartile range (IQR): 6.5 (2.0-11.0) vs. 1.0 (1.0-3.5); P<0.0001]. Despite this difference the number of tumor recurrences was similar in both groups [64% tumor recurrences in the LAS group and 58% in the conventional group, odds ratio (OR) =1.3, P=0.6]. Furthermore, overall survival (OS) was comparable with a median survival of 77.6 and 29.0 months and 2- and 5-year survival rates of 71% and 63% as well as 53% and 36% in the respective cohorts [hazard ratio (HR) =0.74, P=0.43]. Conclusions: Using LAS a significantly higher number of metastases were removed while producing similar long-term results as compared to patients treated by other techniques. Expectably, recurrence rates in metastasized sarcoma patients remain high with either surgical method. Future studies will have to evaluate possible advantages provided by LAS in a prospective manner. PMID- 29600063 TI - Independent long-term result of robotic thymectomy for myasthenia gravis, a single center experience. AB - Background: Robotic thymectomy has been suggested a feasible and safe approach for myasthenia gravis (MG). Few investigations have revealed the independent effect of robotic thymectomy without the confounding impact of immunosuppressive (IM) therapy. Methods: Between May 2009 and December 2012, robotic extended thymectomy was carried out for patients with diagnosis of MG. The clinical data, subsequent neurological therapy and postintervention status were collected. Results: Data of 37 cases was available for analysis. The mean follow-up was 70.0+/-13.3 months. The median age was 40 years. Twelve (32.4%) patients kept free of IM therapy, and 25 (67.6%) patients accepted postoperatively. The overall 5-year complete stable remission (CSR) rate was 40.6% and improvement rate was 81.6%. The young (age <=40) displayed a significant better CSR rate (P=0.015) and a trend of better improvement rate (P=0.050) compared to the old (age >40). Patients without usage of IM therapy showed significant higher CSR rate (P=0.014) and improvement rate (P=0.024) compared to those with usage of IM therapy. Patients with Myasthenia Gravis Foundation of America (MGFA) classes I showed a trend of higher remission rate by multivariate analysis. No significant differences were found for the remission rate according to gender, pathology, and the duration of symptoms. Conclusions: The mono-therapy of robotic thymectomy may bring with a satisfactory long-term result for part of MG patients. Precision selection and individualized therapy are of the most importance. PMID- 29600064 TI - National adoption of video-assisted thoracoscopic surgery (VATS) lobectomy: the Italian VATS register evaluation. AB - Background: The expertise curve of video-assisted thoracoscopic surgery (VATS) lobectomies still stirs debate and controversy both because of the number of procedures to carry out and of the evaluation of the learning threshold. The purpose of our study was the examination of the variables related to the learning curve of the video-assisted approach, to establish what may be an expression of the technical maturity of the surgeon. Methods: The National Register for VATS lobectomy built in 2013 was used to collect data from 65 Thoracic Surgery Units. Out of more than 3,700 patients enrolled, only information from Units with >=100 VATS lobectomies were retrospectively analysed. Unpaired Student's t-tests, Fisher's exact tests, Pearson's chi2 were applied as needed. Cumulative summative analysis and one-way ANOVA were used to identify the expertise curve of VATS lobectomy. Results: Ten institutions contributed a total of 1,679 patients, who were divided into three uniform groups according to the chronological sequence of surgery. The length of utility incision, the number of dissected lymph nodes and the operative time were not statistically significant (P=0.999, P=0.972 and P=0.307, respectively) among groups. Conversion to thoracotomy and postoperative air leaks occurred in 125 (7.44%) and 109 (6.49%) patients, gradually declined in Group 3 with statistical significance (P=0.048 and P=0.00086). Conclusions: The conversion rate and the percentage of air leaks seem to define the expertise of VATS lobectomy, being linked to the ability to manage more complicated surgical cases or intraoperative adverse events. PMID- 29600065 TI - High blood neutrophil-lymphocyte ratio associated with poor outcomes in miliary tuberculosis. AB - Background: It is difficult to predict the prognosis of miliary tuberculosis (TB). We hypothesized that blood neutrophil-lymphocyte ratio (NLR) is an indicator of inflammatory status to reflect independent prognostic significance in patients with miliary TB. The aim of this study is to investigate the relationship between NLR and outcome in miliary TB. Methods: We retrospectively collected data from patients diagnosed with miliary TB in a tertiary referral hospital between January 1995 and January 2016. Results: A total of 96 patients were enrolled. Seventeen patients (18%) died during hospitalization due to miliary TB, and 9 (9%) died additionally during the 1-year follow-up period. Eighteen patients (19%) were diagnosed with acute respiratory distress syndrome (ARDS). In multiple logistic regression analyses, increased NLR was associated with ARDS [adjusted odds ratio, 1.15; 95% confidence interval (CI), 1.03-1.28]. By multivariate Cox regression analysis with adjustment of known prognostic factors including age, sex, body mass index, serum aspartate aminotransferase (AST), and hemoglobin, NLR was an independent predictor of in-hospital mortality [adjusted hazard ratio (aHR), 1.08; 95% CI, 1.03-1.13] and 1-year mortality (aHR, 1.08; 95% CI, 1.05-1.12). Conclusions: Pre-treatment NLR at admission may be a useful biomarker for mortality and development of ARDS in patients with miliary TB. PMID- 29600066 TI - Comparison of closed-chest drainage with rib resection closed drainage for treatment of chronic tuberculous empyema. AB - Background: This study aimed to compare the efficacy of closed-chest drainage with rib resection closed drainage of chronic tuberculous empyema. Methods: This retrospective study reviewed 86 patients with tuberculous empyema in Shanghai Pulmonary Hospital from August 2010 to November 2015. Among these included patients, 22 patients received closed-chest drainage, and 64 patients received rib resection closed drainage. Results: The results showed that after intercostal chest closed drain treatment, 2 (9.09%) patients were recovery, 13 (59.09%) patients had significantly curative effect, 6 (27.27%) patients had partly curative effect, and 1 (4.55%) patient had negative effect. After treatment of rib resection closed drainage, 9 (14.06%) patients were successfully recovery, 31 (48.44%) patients had significantly curative effect, 19 (29.69%) patients had partly curative effect, and 5 (7.81%) patients had negative effect. There was no significant difference in the curative effect (P>0.05), while the average catheterization time of rib resection closed drainage (130.05+/-13.12 days) was significant longer than that (126.14+/-36.84 days) in course of intercostal chest closed drain (P<0.05). Conclusions: This study had demonstrated that closed-chest drainage was an effective procedure for treating empyema in young patients. It was less invasive than rib resection closed drainage and was associated with less severe pain. We advocated closed-chest drainage for the majority of young patients with empyema, except for those with other diseases. PMID- 29600068 TI - Superior vena cava replacement combined with venovenous shunt for lung cancer and thymoma: a case series. AB - Background: Superior vena cava (SVC) replacement is infrequently performed and technically challenging in low-volume centers. Venovenous shunt (VVS) technique is used to reduce SVC pressure during SVC replacement and has not been well reported. This study aimed to add information on this subject and evaluate the surgical outcomes of patients who underwent SVC replacement combined with VVS in our center. Methods: A retrospective analysis of six patients who underwent SVC replacement combined with VVS from September 2011 to February 2017 was performed. Clinical characteristics, pathological features, operative characteristics, postoperative outcomes, and the survival of the six patients were reviewed. Results: There were four males and two females with a median age of 44 years (range, 35-69 years). There were three lung cancer patients and three thymoma patients at a stage from IIIA to IVA. Five patients underwent induction therapy. Complete resection was performed on five patients. One patient underwent internal VVS, and the other five patients underwent external VVS. Prosthesis grafts were employed in five cases and autologous pericardium in one case. Three patients underwent single-vein reconstruction, and the other three patients underwent double-vein reconstruction. The median SVC clamping time was 75 minutes. There were no postoperative deaths or major complications. All patients were alive at follow-up, and no thrombosis was found in any of the grafts. Conclusions: SVC replacement combined with VVS is technically feasible and safe. Although VVS technique is not a must, it may make SVC replacement safer in inexperienced centers. Surgery-based multidisciplinary treatment for selected patients with type T4 lung cancer and SVC involvement or thymoma and SVC involvement may achieve a favorable long-term outcome. PMID- 29600067 TI - Effect of chest tube size on pleurodesis efficacy in malignant pleural effusion: a meta-analysis of randomized controlled trials. AB - Background: Malignant pleural effusion (MPE) develops in approximately 50% of all patients with metastatic cancer. The efficacy of small- vs. large-bore chest tube for pleurodesis in patients with MPE is still not clear. Methods: We performed a meta-analysis to evaluate the efficacy and safety of chest tube size in the management of MPE. A systematic search of Medline (Ovid) and Embase (from 1980 to March 2016) was performed. Randomized clinical trials (RCTs) evaluating the effect of small (<=14 French) vs. large (>14 French) chest tube size on successful pleurodesis for patients with MPE. Of 708 potentially relevant publications, four matched the selection criteria and were included in the meta analysis. Results: Overall relative risk (RR) with 95% confidence intervals (CI) was pooled using a random-effects model. Heterogeneity was assessed using Q statistic (significant at P<0.1). In the 231 patients, the success proportion of pleurodesis as well as complication proportion were comparable between large and small chest tube groups with a pooled RR of 0.90 (95% CI, 0.77-1.05; P=0.19; I2 =17.4%) and 0.95 (95% CI, 0.42-2.15; P=0.90; I2 =0.9%) respectively. Successful pleurodesis and complication proportion for small vs. large chest tubes were 73.8% vs. 82.0% and 13.0% vs. 10.5%, respectively. Conclusions: This meta analysis suggests that small and large chest tubes are both effective treatment for MPE with similar successful pleurodesis and complication proportion. Further RCTs are needed to more clearly determine which size tube is superior. PMID- 29600069 TI - The management of chemical pleurodesis with viscum album in patients with persistent air leakage. AB - Background: Persistent air leak (PAL) after major pulmonary resection or involved with secondary lung disease is prevalent and associated with significant morbidity. Chemical pleurodesis is a practical therapeutic tool to manage the patients with PAL. Among various sclerosing substances, viscum album (fraxini) is considered effective and safe. The aim of this study was to evaluate the efficacy and safety of viscum album pleurodesis in patients with intractable prolonged air leakage. Methods: Between February 2013 and February 2015, 73 consecutive patients who underwent pleurodesis due to PAL were enrolled in this study. Pleurodesis was performed using 100 mg of viscum album (fraxini) at 1 time through the indwelling chest tube. Main studied outcomes were focused on success rate of pleurodesis assessed on chest radiography and cessation of the air leak after procedure. Results: The study population was predominantly male (n=64, 87.7%). The overall success rate was 90.4%. One patient died of pneumonia not related to the viscum album pleurodesis. The mean length of stoppage to air leakage was 28.00+/-22.19 hours. The mean duration of chest tube drainage after pleurodesis was 2.78+/-1.35 days. The mean number of pleurodesis was 1.38+/-0.75. Thirty-six patients (49.3%) complained of chest pain requiring a prescription for pain control. There were no major relevant complications or mortalities. Conclusions: Air leaks remain an important cause of morbidity. This viscum album pleurodesis could be considered as an option for the treatment of prolonged air leak patients, associated with acceptable side effects. PMID- 29600070 TI - Deep sternal wound infection after cardiac surgery: a comparison of three different wound infection types and an analysis of antibiotic resistance. AB - Background: Deep sternal wound infection (DSWI) is a severe complication following cardiac surgery. We compared epidemiology, clinical features, and microbiology of three types of DSWI and examined the antibiotic resistance in DSWI patients. Methods: From 2011 to 2015, 170 adult post-cardiac surgery DSWI patients were recruited for this study and underwent the pectoralis major muscle flap transposition in our department. Results: Of 170 adult patients with DSWI (mean age of 54 years), the majority (99 patients, 58.2%) had type II DSWI. The three types of DSWI patients showed significant differences in terms of gender, smoking history, chronic obstructive pulmonary disease (COPD), length of intensive care unit (ICU) stay, and hospitalization cost (P<0.05). The most common symptoms of DSWI patients were fever and wound dehiscence accompanied by purulent secretions. Types I and II DSWI were more frequently associated with hypoproteinemia and high leucocyte count (P<0.05). Microbiological diagnosis was available for 77 of 170 patients (45.3%). Of 157 pathogens detected, 87 (55.4%) species of gram negative bacilli were identified and most commonly were Pseudomonas aeruginosa (25.5%) and methicillin-susceptible Staphylococcus aureus (20.4%). However, no statistically significant microbiological differences among the three DSWI types were observed (P>0.05). Notably, P. aeruginosa isolates showed 100% resistance to cefazolin and cefuroxime. Meanwhile, the resistance rate of Acinetobacter baumannii isolates to commonly used antibiotics was greater than 70%, while resistance rates of staphylococcus to penicillin-G were 100% and to clindamycin were over 70%. No isolates were resistant to vancomycin, linezolid, and tigecycline. Conclusions: Three types of DSWI exhibit differences in epidemiology and clinical features. P. aeruginosa and S. aureus are the most common pathogens in DSWI patients and antibiotic resistance is a serious concern in these patients. Therefore, prevention and treatment of DSWI should be closely tailored to clinical features, local microbiological characteristics, and resistance patterns of commonly encountered pathogens. PMID- 29600071 TI - Prognostic significance of histologic classification and tumor disappearance rate by computed tomography in lung cancer. AB - Background: We investigated the prognostic value of the International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) classification and assessed the relationship between pathologic invasiveness and tumor disappearance rate (TDR) in lung adenocarcinoma with ground-glass opacity (GGO). Methods: We reviewed data from 202 consecutive patients operated on between 2000 and 2009 for clinical T1-2N0 lung adenocarcinoma with GGO and reclassified their histologic subtypes according to the IASLC/ATS/ERS classification. Thirty-nine patients had adenocarcinoma in situ (AIS), 29 minimally invasive adenocarcinoma (MIA), 75 lepidic predominant invasive adenocarcinoma (LPA), and 59 non-lepidic predominant invasive adenocarcinoma (NLPA). Survival outcomes were compared according to histologic subtype and TDR. Results: The mean age was 58 years and 101 patients (50%) were male. Lobectomy was performed in 161 patients (79.7%), wedge resection in 34 (16.8%), and segmentectomy in 7 (3.5%). Patients with AIS, MIA, and LPA had significantly smaller tumor sizes, earlier pathologic T stages, and lower incidences of lymphatic/pleural invasion than those with NLPA. The 5-year recurrence-free survival (RFS) rates were 95.1%, 94.5%, and 87.6% in the AIS + MIA, LPA, and NLPA groups, respectively (P=0.029). Tumors with a TDR>75% were associated with lepidic predominant histologic subtype and less pathologic invasiveness. The 5-year RFS rates were 97.4% in tumors with a TDR >75% and 87.8% in tumors with a TDR <=75% (P=0.0009). Conclusions: Histologic subtype according to the IASLC/ATS/ERS classification and TDR both correlated with pathologic invasiveness and predicted survival in patients with lung adenocarcinoma with GGO. PMID- 29600072 TI - Aberrant status and clinicopathologic characteristic associations of 11 target genes in 1,321 Chinese patients with lung adenocarcinoma. AB - Background: The aberrant status of target genes and their associations with clinicopathologic characteristics are still unclear in primary lung adenocarcinoma. Methods: The common mutations and translocations of nine target genes were evaluated in 1,247 specimens of surgically-resected primary lung adenocarcinoma. Immunohistochemistry was used to analyze the expressions of programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) in 731 specimens. The frequency of the aberrations and their associations with clinicopathologic characteristics were analyzed. Results: Overall, 952 (76.3%) of 1,247 patients harbored at least one target mutation or translocation: epidermal growth factor receptor (EGFR) (729, 58.5%), v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) (83, 6.7%), human epidermal growth factor receptor 2 (HER2) (82, 6.6%), anaplastic lymphoma kinase (ALK) (23, 1.8%), phosphoinositide-3-kinase catalytic alpha polypeptide (PIK3CA) (20, 1.6%), Ret proto-oncogene RET (15, 1.2%), ROS proto-oncogene 1 receptor tyrosine kinase (ROS1) (12, 1.0%), B-raf proto-oncogene (BRAF) (9, 0.7%), neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS) (3, 0.2%). Fourteen (1.9%) of 731 patients were PD-1 positive and 95 (13.0%) were PD-L1 positive in tumor cells. In men and smokers, there were more frequent KRAS mutations (both P<0.001) and PD-L1 positive tumors (P<0.001, P=0.005, respectively), and less frequent EGFR mutations (P=0.049, <0.001, respectively). In ground-glass opacity (GGO) or ground-glass nodules (GGN), there were more HER2 (P=0.033) but less EGFR (P=0.025) and PIK3CA mutations (P=0.012), and ALK translocations (P=0.014). EGFR (P<0.001), KRAS mutations (P=0.004) and PD L1 positive tumors (P=0.046) were more frequent in older patients, while HER2 (P<0.001), ALK (P=0.005) and ROS1 aberrations (P=0.044) were less frequent. Invasive mucinous adenocarcinoma was significantly associated with KRAS and ALK aberrations (both P<0.001), while solid predominant adenocarcinoma was associated with ROS1 translocations (P=0.036) and PD-L1 expression (P<0.001). KRAS, HER2, and ALK aberrations were scarce in patients with EGFR mutations (all P<0.001), while PD-L1 positive tumors positively correlated with ALK translocations (P=0.031) and negatively correlated with HER2 mutations (P=0.019). Conclusions: Most patients with primary lung adenocarcinoma harbored target gene aberrations. The frequency of each alteration differed in patients depending on clinicopathologic characteristics. PMID- 29600073 TI - MicroRNA expression profile in primary lung cancer cells lines obtained by endobronchial ultrasound transbronchial needle aspiration. AB - Background: Novel cancer biomarkers like microRNA (miRNA) are promising tools to gain a better understanding of lung cancer pathology and yield important information to guide therapy. In recent years, new less invasive methods for the diagnosis and staging of NSCLC have become key tools in thoracic oncology and the worldwide spread of endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA). However, appropriate specimen handling is mandatory to achieve adequate results and reproducibility. The aim of this single centre prospective study was to evaluate the feasibility of a complete miRNA expression profile in fresh NSCLC cell lines obtained by EBUS-TBNA. Methods: Patients with proven NSCLC underwent EBUS-TBNA for the diagnosis of suspect lymph node metastasis, and cytological specimens were collected for epithelial cell culture and miRNA expression analysis. To validate the miRNA expression profile, we compared the results from EBUS-TBNA NSCLC specimens with those obtained from formalin-fixed paraffin-embedded (FFPE) mediastinoscopy specimens. Results: Analysis of the miRNA expression profiles of three independent EBUS-TBNA-derived primary cell lines allowed the screening of 377 different human miRNAs. One hundred and fifty miRNAs were detected in all cell lines. Analysis of the miRNA expression profile in mediastinoscopy specimens showed a strong similarity in the clusters analysed. Conclusions: The miRNA expression profile is feasible and reliable in EBUS-TBNA specimens. Validation of this protocol in fresh cytological specimens represents an effective and reproducible method to correlate translational and clinical research. PMID- 29600074 TI - Presence of pleural adhesions can predict conversion to thoracotomy and postoperative surgical complications in patients undergoing video-assisted thoracoscopic lung cancer lobectomy. AB - Background: The purpose of our cohort study was to investigate the effects of pleural adhesions on perioperative outcomes in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy for non-small-cell lung cancer (NSCLC). Methods: We performed a single-center retrospective analysis on the prospectively maintained dataset at our unit from February 2014 to November 2015. Patients were divided into two groups (Group A: presence of pleural adhesions; Group B: absence of pleural adhesions) according to our grading system of pleural adhesions when entering the chest cavity. Demographic differences in perioperative outcomes between these two groups were initially estimated. A multivariate logistic regression analysis was then performed to confirm the predictive value of the presence of pleural adhesions. Results: A total of 593 NSCLC patients undergoing VATS lobectomy were enrolled. The conversion and postoperative morbidity rates were 3.2% and 29.2%, respectively. There were 154 patients with pleural adhesions (Group A) and 439 patients without pleural adhesions (Group B). Group A patients had significantly higher rates of conversion to thoracotomy (9.1% vs. 1.1%; P<0.001) and surgical complications (24.0% vs. 14.4%; P=0.006) than those of Group B patients. No significant difference was found in the overall morbidity and cardiopulmonary complication rates between these two groups. The presence of pleural adhesions was also significantly associated with the prolonged length of chest tube drainage (log-rank P<0.001) and length of stay (log-rank P=0.032). Finally, the presence of pleural adhesions was identified as an independent risk factor for conversion to thoracotomy [odds ratio (OR) =5.49; P=0.003] and surgical complications (OR =1.94; P=0.033) by multivariate logistic-regression analyses. Conclusions: Presence of pleural adhesions can predict conversion to thoracotomy and postoperative surgical complications in patients undergoing VATS lobectomy for NSCLC. Our study calls for an internationally accepted grading system for the presence of pleural adhesions to stratify the surgical risk. PMID- 29600075 TI - Sarcopenia is a predictor of outcomes after lobectomy. AB - Background: As screening for lung cancer rises, an increase in the diagnosis of early stage lung cancers is expected. Lobectomy remains the standard treatment, but there are alternatives, consideration of which requires an estimation of the risk of surgery. Sarcopenia, irrespective of body mass index, confers a worse prognosis in many groups of patients including those undergoing surgery. Here we examine the association of muscle mass with outcomes for patients undergoing lobectomy. Methods: Consecutive patients undergoing lobectomy were retrospectively reviewed. Preoperative computed tomography scans were reviewed, and cross-sectional area of the erector spinae muscles and pectoralis muscles was determined and normalized for height. Univariate and multivariate analyses were then done to examine for an association of muscle mass with morbidity and short- and long-term mortality. Results: During the study period, there were 299 lobectomies, 278 of which were done by video assisted thoracoscopic surgery. The average age of the patients was 67.5+/-10.6 years. Overall complication rate was 52.2%, pneumonia rate was 8.7%, and the 30-day mortality rate was 1.3%. Mean height adjusted-erector spinae muscle cross-sectional area was 10.6+/-2.6 cm2/m2, and mean height adjusted-pectoralis muscle cross sectional area was 13.3+/-3.8 cm2/m2. The height adjusted cross sectional areas of the erector spinae and pectoralis muscles were not associated with overall complication rate, rate of pneumonia, readmission, or intensive care unit length of stay. The height adjusted-erector spinae muscle cross sectional area was inversely correlated with 30-day mortality risk, odds ratio 0.77 (95% CI, 0.60-0.98, P=0.036). Mean length of stay was 7.0 days (95% CI, 5.5-8.4 days). Multivariate analysis demonstrated a significant inverse association of the height adjusted-erector spinae muscle cross sectional area with length of stay (P=0.019). Conclusions: The height adjusted-erector spinae muscle cross sectional area was significantly associated with 30-day mortality and length of stay in the hospital. Measurement of muscle mass on preoperative computed tomography imaging may have a role to help predict risk of morbidity and mortality prior to lobectomy. PMID- 29600076 TI - Risk factors and methylenetetrahydrofolate reductase gene in congenital heart disease. AB - Background: Congenital heart disease (CHD), which involve congenital cardiovascular malformations that occur during an embryo stage, may be the result of a complex interaction between genetic factors and environmental factors. The homozygous 677 T/T MTHFR gene and potential factors have been associated with CHD. Our objective was to study associations between potential environmental risk factors and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms in CHD. Methods: A total of 346 children with CHD and 237 healthy children were recruited. Their parents were also enlisted in the study and interviewed face-to face to identify potential environmental risk factors. The MTHFR genotype was analyzed by restriction fragment length polymorphism (RFLP). Interactions between environmental risk factors and MTHFR gene polymorphisms were evaluated by the relative excess risk due to interaction (RERI), the attributable proportion due to interaction (AP), and the synergy index (S). Results: There were significant differences in the occupational statuses of the mothers and their levels of drug exposure during gestation between the controls and the cases (P<0.05). These differences significantly increased offspring CHD risk (occupation: OR =5.45, 95% CI: 3.46-8.58; drug exposure: OR =4.91, 95% CI: 2.18-11.09). The frequency of the MTHFR gene 677 TT polymorphism in the mothers who had offspring with CHD was significantly different from that in the non-CHD controls (P<0.05). The frequency of this polymorphism also significantly differed between the children with CHD and the control group (P<0.05). An interaction was identified between the presence of the homozygous 677 TT genotype in the children and the mothers' occupational statuses (RERI =9.43, CI: 0.06-18.91). Conclusions: A significant interaction was found between the homozygous 677 T/T MTHFR gene in children and the maternal occupational status and level of drug exposure during gestation. Avoiding or reducing the exposure of the risk factors mentioned above, strengthening pre-pregnancy checkups and guidance might help to reduce the risk of CHD. PMID- 29600077 TI - Esophageal cancer in elderly patients: a population-based study. AB - Background: As the aging issue and increased elderly esophageal cancer (EC) patients, we sought to study the clinical characteristics, treatment modality and outcomes of EC patients 70 years or older compared with those younger than 70 years old. Methods: The national surveillance, epidemiology, and end results (SEER) database for the period from 1973 to 2013 was analyzed. The patient and treatment characteristics were compared between the age groups. Multivariate Cox proportional hazard regression analyses were also performed to identify independent prognostic factors. Propensity-score matching analyses (PSA) regarding survival after different treatments were also performed in locoregional EC. Results: Compared with the younger group, patients 70 years or older were characterized by having a higher proportion of patients with female gender, white race, localized disease, non-adenocarcinoma and without any treatment, as well as inferior overall survival (OS) [hazard ratio (HR), 1.324] and EC-specific survival (HR, 1.270). In addition, older patients shared same independent prognostic factors with younger patients, including age, histology and race. Specifically, compared with those receiving no intensive treatments, surgery alone (HR, 0.342), both surgery and RT (HR, 0.323) and RT only (HR, 0.525) were favorable among elderly patients, as confirmed by both multivariate adjustment and PSA. Conclusions: Compared to younger EC patients, those 70 years or older showed distinctive clinical characteristics and inferior survival. Despite showing a higher proportion of localized disease, patients 70 years or older were less likely to be subjected to surgery or/and RT. Thus, the role of intensive treatments, which were identified as favorable factors among elderly patients in this study, warrants further investigation. PMID- 29600078 TI - Predicting malignancy of pulmonary ground-glass nodules and their invasiveness by random forest. AB - Background: The purpose of this study was to develop a predictive model that could accurately predict the malignancy of the pulmonary ground-glass nodules (GGNs) and the invasiveness of the malignant GGNs. Methods: The authors built two binary classification models that could predict the malignancy of the pulmonary GGNs and the invasiveness of the malignant GGNs. Results: Results of our developed model showed random forest could achieve 95.1% accuracy to predict the malignancy of GGNs and 83.0% accuracy to predict the invasiveness of the malignant GGNs. Conclusions: The malignancy and invasiveness of pulmonary GGNs could be predicted by random forest. PMID- 29600079 TI - A technique of minimally invasive aortic valve replacement: an alternative to transcatheter aortic valve replacement (TAVR). AB - Minimally invasive aortic valve replacement (AVR) is increasingly being adopted worldwide, in which a right mini-thoracotomy (RT) approach plays an important role. Here we reported a novel technique of AVR via RT using sutureless prosthesis, without rib division or groin incision. Surgical access was performed through an anterior right thoracotomy with 5-cm skin incision placed in the third intercostal space. Percutaneous femoral-femoral cardio-pulmonary bypass (CPB) was applied under fluoroscopy guidance to avoid groin incision. A 5-mm stab incision was made in the right chest wall for aortic cross-clamping. A sutureless bioprosthetic valve was utilized in the limited operative field, which reduced the cross-clamp and CPB time. The patient was discharged on post-operative day 2, without obvious cross-valvar gradient, and with no pain or other complication. This report offers a more minimally invasive approach to AVR with proven durable valves, which can benefit high-risk patients. PMID- 29600080 TI - Emergency drain for post pneumonectomy bronchopleural fistula: a drain placement technique based on the siphon principle. AB - Post pneumonectomy bronchopleural fistula (BPF) is a life-threatening complication requiring pleural cavity drainage to avoid acute mediastinal shift and contralateral aspiration pneumonia. Chest drain insertion in this situation may be technically difficult because of drastic anatomical changes such as mediastinal dislocation, diaphragm elevation and, sometimes, massive subcutaneous emphysema. In addition, the most important part of the pleural cavity to be drained is the costophrenic recess that is scarcely drained by a standard chest tube with its tip aiming high and upwards. We propose a safe, simple and effective technique based on the siphon principle to drain the lowest part of the pleural cavity. PMID- 29600081 TI - Intramedullary reinforcement of sternal fixation with autologous xiphoid tenon. AB - Minimally invasive cardiac surgery through a partial sternotomy or a ministernotomy is popular. However, the transverse nonunion of the sternum will be a potential complication. Valid and valuable techniques have been introduced for securing the sternotomy fixation. Most of them are focused on the materials or methods for extrinsic reinforcement. A new concept, focused on the intramedullary reinforcement of the sternal fixation, was designed by incarcerating a cancellous portion of the autologous xiphoid in the marrow space of the inter-segmental junction of the partial sternotomy. This autologous xiphoid tenon method is simple, reliable, and reproducible without additional requirement of device implantation or an iliac incision for the bone grafting. PMID- 29600082 TI - Four arms robotic-assisted pulmonary resection-right lower/middle lobectomy: how to do it. AB - In the last few years, robotic approach for anatomic lung resection has brought an innovative development in minimally invasive thoracic surgery. This study analyzes the technical aspects of performing the hilar dissection for a lobectomy via robotic approach. With a detailed step-by-step description and essential tips and videos, in this paper, we report the procedure to carry out a four-arm robotic middle and lower lobectomy. PMID- 29600084 TI - Surgical approaches in patients with oligometastatic non-small cell lung cancer. AB - In recent years, retrospective analyses have suggested that an oligometastatic state could exist, but the best evidence to date that a temporary oligometastatic disease exists for lung cancer mainly derives from the survival data on retrospective patients underwent surgical resection of a single M1 site and all intrathoracic disease. The critical determinates of long-term survival include definitive treatment of the primary non-small cell lung cancer (NSCLC), a single organ site of synchronous or metachronous disease, a long disease-free interval between treatment of the primary NSCLC and development of metastases, and the absence of intrathoracic lymph node (N0) disease. The ongoing development of innovative approaches to local therapy and treatment directed to the oligometastatic sites should be defined in future studies. PMID- 29600083 TI - Influence of estrogen in non-small cell lung cancer and its clinical implications. AB - Lung cancer (LC) is the leading cause of cancer death in men worldwide and has significantly increased in women. Differences in non-small cell lung cancer (NSCLC) behavior, prognosis, and response to treatment have been reported by sex and hormonal status, with premenopausal women presenting the worst prognosis compared to postmenopausal women and men. Additionally, the use of hormonal replacement therapy significantly increases NSCLC mortality; supporting the role of estrogen signaling in the pathogenesis of LC. The mechanisms by which estrogen promotes lung carcinogenesis have not been fully elucidated. Estrogen, through its receptor, can stimulate LC cell proliferation, death resistance, angiogenesis, migration and metastasis. Estrogen also induces expression of pro inflammatory proteins and ligands that promote tumor evasion, suggesting that estrogen might modify the microenvironment and anti-tumor immune response. Recent reports have shown an interaction between the epidermal growth factor receptor (EGFR) pathway and estrogen signaling in lung adenocarcinoma, whence, combined treatment based on tyrosine kinase inhibitors (TKIs) and antiestrogen therapy is beginning to be evaluated. This review focuses on the differences in NSCLC behavior by sex and hormonal status, highlighting the role of estrogen and its receptors in lung carcinogenesis and LC prognosis. Due to the importance of estrogen in NSCLC development and progression we finally discuss the potential of antiestrogen therapy in LC treatment and show the results from preclinical and clinical trials. PMID- 29600085 TI - Current role of standardized uptake valuemax-derived ratios in N2 fluorine-18 fluorodeoxyglucose positron-emission tomography non-small cell lung cancer. AB - Mediastinal staging is a crucial moment in management of non-small cell lung cancer (NSCLC) patients. In integrated pathways, 18-fluorine fluorodeoxyglucose positron-emission tomography (18F-FDG-PET/CT) is an indispensable imaging resource with its peculiarities and its limitations. A critical review of work up protocols would certainly help to standardize procedures with important reflections also on the diagnostic value of this examination. In this regard, new semi-quantitative and semi-qualitative indexes have been proposed with the aim of increasing the accuracy of 18F-FDG-PET/CT in mediastinal lymph node staging. These latter, such as SUVn/t and SUV indexes, seem to overcome the problem of spatial resolution and discrimination of malignancy by endorsing a new predictive and prognostic role. PMID- 29600087 TI - Diagnostic and therapeutic challenges in managing persistent air leaks. AB - Persistent air leak (PAL) is a common and challenging condition associated with increased morbidity and mortality, intensive care unit admission, and prolonged hospital stay. Multiple medical and surgical approaches have been developed to manage PAL. Depending on the etiology of PAL, surgical management may be effective and usually performed using video-assisted thoracoscopic surgery (VATS). Medical management is less invasive and consists of pleural or bronchoscopic methods. The non-surgical techniques for the management of PAL have not been investigated in large prospective studies, and so their use is mostly guided by observational data. Specifically, the role of intrabronchial valve (IBV) placement for PAL has been the subject of an ever-increasing number of case reports and series documenting successful deployment of IBVs for both surgical and medical PAL. In this case-based discussion, we describe three patients with non-surgical PAL who were managed using multiple modalities, including both surgical and medical approaches. These cases illustrate the challenges in identifying the location of the air leak and in the application of various therapeutic options. PMID- 29600088 TI - The J-waves of hypothermia. AB - Prominent J-waves are observed in several clinical conditions many of which are highly arrhythmogenic and may lead to ventricular fibrillation (VF) and/or sudden cardiac death. We present the case of a 34-year-old male patient with hypothermia. Prominent J-waves (Osborn waves) and prolonged QT interval was evident in nearly every lead. Early recognition of these arrhythmogenic electrocardiogram (ECG) findings and treatment of hypothermia is important to minimize the risk of arrhythmic events. PMID- 29600086 TI - Exercise training in pulmonary arterial hypertension. AB - Pulmonary arterial hypertension (PAH) is characterized by a continuous increase in pre-capillary pulmonary vascular resistance (PVR) with a progressive reduction of cardiac output (CO). Similar to what occurs in left heart failure (HF), this represents the initial phase of a syndrome characterized by the progressive development of dyspnea and fatigue with increasing deterioration of exercise tolerance. Although the therapies introduced in the last two decades have determined a significant improvement of the clinical conditions of PAH patients, they have a little impact on exercise capacity and prognosis. However, as previously demonstrated for HF, recent pilot studies have reported that physical and respiratory rehabilitation may have a specific role in the management of PAH. Despite potential risks, so far all studies agree that exercise training (ET) improves exercise capacity, quality of life (QoL), muscle function and pulmonary circulation. We will review the pathophysiological mechanisms underlying the functional incompetence of PAH patients, the effects of ET on clinical and functional parameters, the selection criteria for inclusion of patients in a training program, the suggested monitoring of beneficial effects or possible side effects induced by ET. Finally, we discuss of the possible exercise induced amelioration of prognosis in PAH. PMID- 29600089 TI - Diagnostic criteria for obstructive sleep apnea: time for reappraisal.

Middle lobe syndrome which is irresponsive to conservative therapies also calls for surgical intervention. We reported the case of a 65-year-old male who was diagnosed with coexistent thymic carcinoma and non-obstructive middle lobe syndrome. Before the operation, we took measures including repeated sputum examination, physical therapy, postural sputum drainage and bronchodilator inhalation. After removal of the mediastinal neoplasm, venous antibiotics were used to prevent pneumonia. The preexistent cough with purulent expectoration still lasted, but no pulmonary infection occurred. Our report indicates that middle lobe syndrome may not increase respiratory complications after midline sternotomy if it receives proper treatments before the operation. For patients with concurrent thymic carcinoma and persistent middle lobe atelectasis, the thymic tumor might be treated with priority to increase the chance of complete resection. PMID- 29600098 TI - Interrupted right-sided aortic arch: performance of umbilical xenograft after primary neonatal corrective surgery. AB - Interrupted aortic arch (IAA) associated with right-sided aorta descendens is a rare congenital malformation. We present a case of a female patient who was diagnosed with type B IAA and received primary corrective surgery as a neonate. A bovine umbilical vascular graft was used to establish aortic arch continuity. Thirty-nine years later the same patient presents with graft-dilatation and a distal aneurysm requiring a surgery. This case shows a late complication of a biological xenograft in term of long-term material performance. Moreover, it highlights the necessity for regular follow-ups in order to detect and treat late onset complications respectively. PMID- 29600099 TI - Massive pericardial effusion after Nuss procedure: to drain or not to drain? AB - A 11-year-old boy presented with refractory fever and dyspnoea after Nuss procedure. Massive pericardial effusion was detected on computer tomography scan performed under corticosteroid cover for his asthmatic history. With rapid clinical improvement following corticosteroids, a clinical diagnosis of post pericardiotomy syndrome (PPS) was made. Following a course of oral prednisolone, serial blood test and echocardiogram showed gradual resolution of inflammation and pericardial effusion. This rarely-reported case serves as a poignant reminder to PPS after Nuss procedure as a cause of febrile massive pericardial effusion. Early therapeutic trial of corticosteroids may prevent clinical deterioration, and have invasive pericardial drainage avoided. PMID- 29600100 TI - Unusual cardiac paraganglioma mimicking an atypical carcinoid tumor of the lung. AB - We present a case of unusual cardiac paraganglioma (PG) initially misdiagnosed as atypical carcinoid tumor of the lung and discuss key clinical and pathologic characteristics that guide surgical management of these rare chromaffin cell tumors. A 64-year-old female with persistent cough and back pain was found to have a 4 cm * 3 cm mass abutting multiple cardiopulmonary structures. A biopsy was performed at an outside institution and pathology reported "atypical neuroendocrine carcinoma, consistent with carcinoid". The patient was transferred to our institution and pericardial resection with right pneumonectomy was performed to excise the tumor. Histology of the mass was that of PG with multiple ethanol embolizations. Immunohistochemical examination revealed that type I (chief) cells were positive for neuroendocrine markers (chromogranin A and synaptophysin), while type II (sustentacular) cells were positive for S100. There was no evidence of atypical carcinoid tumor in the lung. PG is an entity of chromaffin cell tumors that often affects the adrenal glands and carotid body. PG rarely occurs in the thoracic region, accounting for just 1-2% of all PG. Proper diagnosis of cardiac PG is challenging owing to its rare prevalence, subtle symptoms of presentation, and the neuroendocrine histopathological features it shares with atypical carcinoids. These tumors are typically benign and are best treated by surgical resection. Our report examines the approach to appropriate diagnosis of cardiac PG vs. atypical carcinoid, preoperative management, and surgical treatment by describing successful resection through thoracotomy without the use of cardiopulmonary bypass.

We describe our preoperative planning for vascular control and possible reconstruction as well as our approach for safe resection. PMID- 29600102 TI - Pneumatosis intestinalis after lung transplantation for pulmonary graft-versus host disease. AB - Pneumatosis intestinalis, which could complicate a spectrum of clinical conditions ranging from benign to life-threatening, is a rarely encountered complication after lung transplantation (LT). We describe two cases in which PI developed as a complication following LT for pulmonary graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT). In addition to the long-term immunosuppression administered for pulmonary GVHD, the intense immunosuppression needed after LT might increase the risk of PI in lung transplant recipients after HSCT. Conservative therapy should be considered for the treatment of PI developing after LT. PMID- 29600103 TI - Report of a lung carcinoma extended to the left atrium through pulmonary vein. AB - Lung cancers may extend along or grow through the pulmonary veins to invade or lie within the left atrium (LA). A 62-year-old man, previously healthy, presented with 1-month ventilatory-independent right hemithorax back pain, dry cough and large effort dyspnea. He also referred weight loss of 12 kg in 10 months and denied hemoptysis. As antecedents, he smoked for 40 years and moderate daily alcoholism. On physical examination, the patient was in good general condition, hydrated and regular respiration at rest [blood pressure (BP) =120/80 mmHg; heart rate (HR) =90 bpm; respiratory rate (RR) =16 rpm]. Cardiac auscultation revealed two standard rhythmic sounds without murmurs. Pulmonary auscultation revealed a slightly diminished vesicular murmur in the lower 1/3 of the right hemithorax without adventitious noises. Chest radiography showed a mass over the right lower lung. A CT scan confirmed the radiography image with the mass extending along the right inferior pulmonary vein and a tumor in the LA. Transthoracic and transesophageal echocardiography revealed large mass within the LA (occupying almost the entire cavity), measuring about 10 cm * 3 cm at its largest diameter, prolapsing into the left ventricle. Bronchoscopy, head CT scan, and whole-body bone scintigraphy investigation did not show any distant metastasis. The patient was successfully operated removing the intracardiac and inferior pulmonary vein tumor with the aid of cardiopulmonary bypass, followed by a right inferior lobectomy carried out after 25 days. After 30 days from surgery presented seizures associated a brain metastasis evidenced by CT when adjuvant radio and chemotherapy was started. During the next 90 days, the clinical conditions worsened, and the patient died 4 months after the surgical treatment. The case report has two primary justifications, even considering the poor outcome: (I) rarity and (II) the possibility of the surgical treatment. PMID- 29600104 TI - Identifying interlobar fissure in a Craig grade 4 fissureless patient by near infrared thoracoscopy. AB - Traditionally, surgeons can only count on their naked eyes to identify the fissure in patients with incomplete fissures, which often cause surgical approach into the fissural parenchyma and may lead to postoperative prolonged air leak (PAL). We describe a novel technique using near-infrared (NIR) thoracoscopy with indocyanine green (ICG) to identify the fissure accurately and real-timely for the first time in a patient with totally fused oblique fissure (Craig grade 4). PMID- 29600105 TI - Fan-shaped ground-glass opacity (GGO) as a premonitory sign of pulmonary infarction: a case report. AB - Radiological findings of pulmonary infarction have been well characterized mainly in established infarction. However, the early course CT appearance of patients who develop pulmonary infarction has not yet been fully elucidated. A 50-year-old female with a history of postmenopausal hormone replacement therapy (HRT) presented with dry cough and high-resolution computed tomography (HRCT) findings of fan-shaped segmental ground-glass opacity (GGO) in the right lower lobe. As the parenchymal density in the GGO gradually enlarged over a period of 4 weeks in spite of antibiotic treatment, the patient was referred to our hospital on clinical suspicion of bronchioloalveolar cell carcinoma. However, the pathological findings of a transbronchial biopsy of the lesion were compatible with pulmonary infarction. After an endoscopic examination, the typical CT appearance of established pulmonary infarction was observed. Moreover, enhanced CT detected an intraluminal filling defect in the right lower lobe artery suggesting peripheral pulmonary emboli. Our case was a peripheral pulmonary infarction probably induced by HRT, and suggested that fan-shaped GGO may be a premonitory sign of pulmonary infarction. PMID- 29600106 TI - Systemic air embolism after computed tomography-guided hook wire localization: two case reports and literature review. AB - Computed tomography (CT)-guided hook wire localization is often used to identify small nodules prior to video-assisted thoracoscopic surgery (VATS). Pneumothorax, intrapulmonary hemorrhage, and wire dislodgement are well-known complications associated with the former procedure, but systemic air embolism (SAE) is an extremely rare and potentially fatal complication. We encountered two cases of SAE; one patient showed neurologic symptoms, whereas the other did not. With the patient in the supine position, 100% oxygen was inhaled via a face mask. Subsequently, symptoms were resolved, and we performed planned surgeries on that day. Operative and postoperative courses were uneventful, and both patients were discharged without any sequelae. In this case report, we describe our experience with the two patients and review related literature. PMID- 29600107 TI - Missed diagnosis of esophageal leiomyoma leading to esophagectomy: a case report and review of literatures. AB - Leiomyomas are the most common benign esophageal neoplasm. About half of them were smaller than 5 cm and asymptomatic with a stable size for many years. Esophageal leiomyomas that excess than 5 cm in size may develop as a consequence of giant one at rapid growth rate. This case report specifically describes a mid aged woman who experienced a missed diagnosis of an esophageal leiomyoma over three years, which was covered by mediastinal thymolipoma and it subsequently developed as a giant tumor occupying the entire esophagus that makes the simple enucleation impossible. A surgical intervention of esophagectomy had to be performed to manage this entity. PMID- 29600108 TI - Hydroxychloroquine-induced cardiomyopathy and heart failure in twins. AB - Hydroxychloroquine (HCQ)-induced cardiomyopathy is one of the rare but severe complications following prolonged HCQ use. However, the exact mechanism of HCQ cardiotoxicity remains unclear and it is difficult to identify risk factors. We present a case of twin sisters who both suffered from systemic lupus erythematosus (SLE) and HCQ-induced cardiomyopathy presenting with decompensated heart failure (HF), suggesting that genetic predisposition might be a factor in HCQ-induced cardiomyopathy. PMID- 29600109 TI - Two cases of "stone heart" with fatal outcome. AB - The "stone heart" syndrome is a rare but often fatal complication of cardiac surgery associated with hypertrophy of the myocardium. The mechanisms behind the syndrome are not fully understood. In this case report, we describe two cases of stone heart in newborn girls. Both girls were born with congenital heart abnormalities including ventricular septum defects (VSD), hypertrophy of the myocardium and patent arterial duct (PDA), which was prenatally diagnosed. In each of the two cases, the stone heart became evident immediately after initiating cardiopulmonary bypass, and ended fatally. PMID- 29600110 TI - CT angiography for coronary graft assessment. PMID- 29600112 TI - Determination of Phenolic Acids in Sugarcane Vinasse by HPLC with Pulse Amperometry. AB - A reversed-phase liquid chromatographic separation with pulsed amperometric detection of phenolic acids at a glassy carbon electrode is described. Chromatographic separation was carried out in isocratic conditions using 0.20 mol.L-1 acetic acid (pH 5.0)/water (80 : 20, v/v) as mobile phase under constant working potential mode of 0.80 V. Chromatographic peaks presented high resolution and separation. Calibration curves exhibited excellent correlation coefficients, above 0.995. Linear ranges of the analytes, in mg L-1, were of 0.018-18 (gallic acid), 0.146-19 (vanillic acid), 0.13-17 (caffeic acid), 0.016-16 (ferulic acid), and 0.008-17 (p-coumaric acid), respectively. Limits of detection ranged from 1.6 to 97 MUg.L-1 and precision varied in 1.73-3.78% interval. Concentrations of 19 +/- 0.51 mg.L-1 and 7.8 +/- 2.5 mg.L-1 were found for vanillic and caffeic acids, respectively, in a sugarcane vinasse sample. Gallic, ferulic, and p-coumaric acids were not detected. Recovery results demonstrated that the proposed method is accurate, and it can be used to detect and quantify phenolic acids in sugarcane vinasse without any influence of interferents. PMID- 29600113 TI - Relationships between Translation and Transcription Processes during fMRI Connectivity Scanning and Coded Translation and Transcription in Writing Products after Scanning in Children with and without Transcription Disabilities. AB - Students with transcription disabilities (dysgraphia/impaired handwriting, n = 13 or dyslexia/impaired word spelling, n = 16) or without transcription disabilities (controls) completed transcription and translation (idea generating, planning, and creating) writing tasks during fMRI connectivity scanning and compositions after scanning, which were coded for transcription and translation variables. Compositions in both groups showed diversity in genre beyond usual narrative expository distinction; groups differed in coded transcription but not translation variables. For the control group specific transcription or translation tasks during scanning correlated with corresponding coded transcription or translation skills in composition, but connectivity during scanning was not correlated with coded handwriting during composing in dysgraphia group and connectivity during translating was not correlated with any coded variable during composing in dyslexia group. Results are discussed in reference to the trend in neuroscience to use connectivity from relevant seed points while performing tasks and trends in education to recognize the generativity (creativity) of composing at both the genre and syntax levels. PMID- 29600114 TI - Participatory group prenatal education using photonovels: Evaluation of a lay health educator model with low-income Latinas. AB - Objective: The objective of this research was to examine the effectiveness of a participatory prenatal education program for low-income Latinas. Lay health educators facilitated groups using photonovels and experiential learning activities. Methods: We used a community-based participatory research approach with a mixed method evaluation. Data included participant pre- and post-test surveys, focus groups, and a medical record review of participant outcomes and a control-match group who received usual care. Results: Participants (n=43) showed a significant increase in their knowledge of pregnancy, childbirth, and breastfeeding (P < .001) and a significant increase in confidence at being able to navigate their pregnancies, care for themselves and their babies, and interact with health professionals (P <= .05). They reported an increase in social support, a deeper understanding of information from medical providers, greater engagement, and behavior changes. There were no statistically significant differences in health outcomes between the participants and the control group. Conclusions: This study demonstrated that 1) a participatory prenatal education program can be an effective way to foster health literacy and empowerment among low-income Latinas; and 2) trained lay educators can be effective group facilitators. The intervention's tripartite approach offers a vehicle for health professionals to partner with Latino communities to promote active participation and capacity building for health and change. This strategy could be adapted and tested with other topics and communities. PMID- 29600115 TI - The Elusive Nature of Truth in Scientific Studies and the Importance of Peer Review. PMID- 29600116 TI - Reducing Spatial Uncertainty Through Attentional Cueing Improves Contrast Sensitivity in Regions of the Visual Field With Glaucomatous Defects. AB - Purpose: Current clinical perimetric test paradigms present stimuli randomly to various locations across the visual field (VF), inherently introducing spatial uncertainty, which reduces contrast sensitivity. In the present study, we determined the extent to which spatial uncertainty affects contrast sensitivity in glaucoma patients by minimizing spatial uncertainty through attentional cueing. Methods: Six patients with open-angle glaucoma and six healthy subjects underwent laboratory-based psychophysical testing to measure contrast sensitivity at preselected locations at two eccentricities (9.5 degrees and 17.5 degrees ) with two stimulus sizes (Goldmann sizes III and V) under different cueing conditions: 1, 2, 4, or 8 points verbally cued. Method of Constant Stimuli and a single-interval forced-choice procedure were used to generate frequency of seeing (FOS) curves at locations with and without VF defects. Results: At locations with VF defects, cueing minimizes spatial uncertainty and improves sensitivity under all conditions. The effect of cueing was maximal when one point was cued, and rapidly diminished when more points were cued (no change to baseline with 8 points cued). The slope of the FOS curve steepened with reduced spatial uncertainty. Locations with normal sensitivity in glaucomatous eyes had similar performance to that of healthy subjects. There was a systematic increase in uncertainty with the depth of VF loss. Conclusions: Sensitivity measurements across the VF are negatively affected by spatial uncertainty, which increases with greater VF loss. Minimizing uncertainty can improve sensitivity at locations of deficit. Translational Relevance: Current perimetric techniques introduce spatial uncertainty and may therefore underestimate sensitivity in regions of VF loss. PMID- 29600117 TI - Objective Evaluation of Visual Fatigue Using Binocular Fusion Maintenance. AB - Purpose: In this study, we investigated whether an individual's visual fatigue can be evaluated objectively and quantitatively from their ability to maintain binocular fusion. Methods: Binocular fusion maintenance (BFM) was measured using a custom-made binocular open-view Shack-Hartmann wavefront aberrometer equipped with liquid crystal shutters, wherein eye movements and wavefront aberrations were measured simultaneously. Transmittance in the liquid crystal shutter in front of the subject's nondominant eye was reduced linearly, and BFM was determined from the transmittance at the point when binocular fusion was broken and vergence eye movement was induced. In total, 40 healthy subjects underwent the BFM test and completed a questionnaire regarding subjective symptoms before and after a visual task lasting 30 minutes. Results: BFM was significantly reduced after the visual task (P < 0.001) and was negatively correlated with the total subjective eye symptom score (adjusted R2 = 0.752, P < 0.001). Furthermore, the diagnostic accuracy for visual fatigue was significantly higher in BFM than in the conventional test results (aggregated fusional vergence range, near point of convergence, and the high-frequency component of accommodative microfluctuations; P = 0.007). Conclusions: These results suggest that BFM can be used as an indicator for evaluating visual fatigue. Translational Relevance: BFM can be used to evaluate the visual fatigue caused by the new visual devices, such as head-mount display, objectively. PMID- 29600118 TI - Automated Method of Grading Vitreous Haze in Patients With Uveitis for Clinical Trials. AB - Purpose: Uveitis is associated with accumulation of exudate in the vitreous, which reduces fundus visibility. The condition is assessed in patients by subjectively matching fundus photographs to a six-level (NIH) or nine-level (Miami) haze scale. This study aimed to develop an objective method of assessing vitreous haze. Methods: An image-processing algorithm was designed that quantifies vitreous haze via high-pass filtering, entropy analysis, and power spectrum integration. The algorithm was refined using nine published photographs that represent incremental levels of fundus blur and applied without further refinement to 120 random fundus photographs from a uveitis image library. Computed scores were compared against the grades of two trained readers of vitreous haze and against acutance, a generic measure of image clarity, using Cohen's kappa and Gwet's AC statistics. Results: Exact agreement between algorithm scores and reader grades was substantial for both NIH and Miami scales (kappa = 0.61 and 0.67, AC = 0.82 and 0.92). Within-one (kappa = 0.78 and 0.82) and within-two (kappa = 0.80 and 0.84) levels of agreement were almost perfect. The correspondence was comparable to that between readers. Whereas, exact (kappa = 0.45 and 0.44, AC = 0.73 and 0.75), within-one (kappa = 0.69 and 0.68), and within-two (kappa = 0.73 and 0.72) levels of agreement for the two scales were moderate to substantial for acutance calculations. Conclusions: The computer algorithm produces a quantitative measure of vitreous haze that correlates strongly with the perception of expert graders. Translational Relevance: The work offers a rapid, unbiased, standardized means of assessing vitreous haze for clinical and telemedical monitoring of uveitis patients. PMID- 29600119 TI - A Rapid Extraction Method to Quantify Drug Uptake in Contact Lenses. AB - Purpose: To develop a simple extraction procedure to quantify the uptake of four topical ocular pharmaceutical drugs into contact lenses (CLs). Methods: Four silicone hydrogel (SH) CLs (balafilcon A, senofilcon A, lotrafilcon B, comfilcon B) and four conventional hydrogel (CH) CLs (nesofilcon A, hilafilcon B, nelfilcon A, etafilcon A) were evaluated. The drugs studied were natamycin, moxifloxacin, timolol maleate, and ketotifen fumarate. For drug incubation, three CLs of each type were placed in 1 mL of 1 mg/mL drug-loading solution for 24 hours. The lenses were then extracted in 2 mL methanol for 2 hours. This process was repeated to obtain a total of three extraction cycles. Detection of natamycin, moxifloxacin, ketotifen fumarate, and timolol maleate were measured by absorbance at 305, 287, 297, and 295 nm, respectively. Results: The majority of the drugs were extracted after the first extraction cycle (P < 0.001). For moxifloxacin and timolol, CH CLs had higher drug uptake than SH CLs (P < 0.05). There were no differences in drug uptake between CH CLs and SH CLs for natamycin and ketotifen (P > 0.05). Conclusions: This study provides a simple approach to determine drug uptake into CLs. This method can also be modified, such as changing the extraction time, extraction cycles, or extraction solvent to better suit other drugs and CL combinations. Translational Relevance: There is considerable interest in using CLs for ocular drug delivery. Accurately quantifying drug uptake on CLs has been a challenge. Hence, this study provides a simple method to quantify drug uptake in CLs. PMID- 29600121 TI - Reviewers. PMID- 29600120 TI - Towards Standardization of Quantitative Retinal Vascular Parameters: Comparison of SIVA and VAMPIRE Measurements in the Lothian Birth Cohort 1936. AB - Purpose: Semiautomated software applications derive quantitative retinal vascular parameters from fundus camera images. However, the extent of agreement between measurements from different applications is unclear. We evaluate the agreement between retinal measures from two software applications, the Singapore "I" Vessel Assessment (SIVA) and the Vessel Assessment and Measurement Platform for Images of the Retina (VAMPIRE), and examine respective associations between retinal and systemic outcomes. Method: Fundus camera images from 665 Lothian Birth Cohort 1936 participants were analyzed with SIVA and VAMPIRE. Intraclass correlation coefficients (ICC) and Bland-Altman plots assessed agreement between retinal parameters: measurements of vessel width, fractal dimension, and tortuosity. Retinal-systemic variable associations were assessed with Pearson's correlation, and intersoftware correlation magnitude differences were examined with Williams's test. Results: ICC values indicated poor to limited agreement for all retinal parameters (0.159-0.410). Bland-Altman plots revealed proportional bias in the majority, and systematic bias in all measurements. SIVA and VAMPIRE measurements were associated most consistently with systemic variables relating to blood pressure (SIVA r's from -0.122 to -0.183; VAMPIRE r's from -0.078 to -0.177). Williams's tests indicated significant differences in the magnitude of association between retinal and systemic variables for 7 of 77 comparisons (P < 0.05). Conclusions: Agreement between two common software applications was poor. Further studies are required to determine whether associations with systemic variables are software-dependent. Translational Relevance: Standardization of the measurement of retinal vascular parameters is warranted to ensure that they are reliable and application-independent. This would be an important step towards realizing the potential of the retina as a source of imaging-derived biomarkers that are clinically useful. PMID- 29600122 TI - Addition of a Short Course of Prednisolone to a Gluten-Free Diet vs. Gluten-Free Diet Alone in Recovery of Celiac Disease: A Pilot Randomized Controlled Trial. AB - Background A gluten-free diet (GFD) is the standard of care in the management of patients with celiac disease, but clinical and histological recovery are often delayed. In newly diagnosed patients, strict compliance to GFD is difficult to achieve; this is especially true in developing countries where gluten-free food is often difficult to obtain. Steroids, when used alone, can be effective in inducing recovery in patients with celiac disease. We performed a randomized controlled trial to study the effect of a short course of prednisolone combined with a GFD on the recovery of celiac disease. Materials and methods This study was a single-center, randomised, open-label trial. This investigation was done in a pediatric gastroenterology unit of a tertiary teaching hospital in north India.Twenty-eight newly diagnosed celiac disease patients were enrolled in the study. Prednisolone was given at 1 mg/kg for four weeks; duodenal biopsies and IgA anti-tissue transglutaminase (tTg) levels were assessed at eight weeks, six months, and 12 months from the start of the study. Outcome measures The primary outcome measures used to indicate clinical, histological, and immunological recovery of celiac disease were clinical improvement at eight weeks and the proportion of patients with improved histology by at least one grade and who were tissue transglutaminase (tTg) seronegative at eight weeks. The secondary measures were the proportion of patients showing normalization of histological features and the proportions of patients becoming seronegative at six months and one year of GFD. Results Patients were randomized into the GFD only (n = 14) or GFD with prednisolone (GFD+P) (n = 14) groups. No significant differences were detected in clinical recovery at eight weeks; none of the patients became seronegative at eight weeks, six months, or 12 months. The proportion of patients with improvement in histology by at least one grade was higher in the GFD+P group at eight weeks, and there was no difference in overall histological improvement at 12 months after starting treatment. Conclusion The addition of a short course of prednisolone to a GFD does not affect clinical and serological recovery but might result in rapid histological recovery compared to a GFD alone in patients newly diagnosed with celiac disease. PMID- 29600123 TI - Association Between Baseline Blood Pressures, Heart Rates, and Vasovagal Syncope in Children and Adolescents. AB - BACKGROUND: Vasovagal syncope is the most common cause of syncope in children and adults, accounting for 50-66% of unexplained syncope. There are no studies establishing the relationship between syncope, baseline heart rate, and blood pressure. OBJECTIVE: To identify a possible association between baseline blood pressure and heart rate with syncope. DESIGN/METHODS: We conducted a questionnaire-based chart review study. A questionnaire was distributed to the guardian of children between eight and 18 years of age who attended the Pediatric Ambulatory Care Clinic at Flushing Hospital Medical Center. Based on the responses in the questionnaire, subjects were classified either as cases (positive for syncope) or controls (negative for syncope). Children and adolescents with neurological, cardiac, or any medical condition that can cause syncopal episodes were excluded from the study. Data collected from the questionnaire included age, gender, ethnicity, medical history, family history of syncope, and the amount of salt used in food. Anthropometric and vital signs for the current visit (height, weight, BMI, blood pressure, and heart rate) and vital signs from two previous visits were collected from electronic medical records. The data was analyzed using t-test and chi-square test with Microsoft Excel software (Microsoft Office Standard, v. 14, Microsoft; 2010); p<0.05 was considered significant. RESULTS: A total of 197 subjects were included in this study. There were 18 cases and 179 controls. Of the cases, (4/18) 22.2% were more likely to have a systolic blood pressure lower than the 10th percentile for their gender, age, and height as compared with controls (7/179) 3.9%, p = 0.003. The subjects with a history of syncope were more likely to add salt to their food (p = 0.004). There were no significant differences between cases and controls for age, gender, ethnicity between cases and controls for systolic blood pressure. No significant difference was observed between the heart rates of cases and controls. CONCLUSIONS: Children and adolescents with syncope were more likely to have a systolic blood pressure lower than the 10th percentile, and there was no difference in the baseline heart rate. In addition, children with syncope were more likely to add salt to their food. PMID- 29600124 TI - Palatal Injection does not Block the Superior Alveolar Nerve Trunks: Correcting an Error Regarding the Innervation of the Maxillary Teeth. AB - The superior alveolar nerves course lateral to the maxillary sinus and the greater palatine nerve travels through the hard palate. This difficult three dimensional anatomy has led some dentists and oral surgeons to a critical misunderstanding in developing the anterior and middle superior alveolar (AMSA) nerve block and the palatal approach anterior superior alveolar (P-ASA) nerve block. In this review, the anatomy of the posterior, middle and anterior superior alveolar nerves, greater palatine nerve, and nasopalatine nerve are revisited in order to clarify the anatomy of these blocks so that the perpetuated anatomical misunderstanding is rectified. We conclude that the AMSA and P-ASA nerve blockades, as currently described, are not based on accurate anatomy. PMID- 29600125 TI - Overtesting in Japan.

Some frail older people become disabled through stroke, pneumonia, hip fracture, and other diseases. Sarcopenia, malnutrition, and polypharmacy tend to worsen disability in older people. Rehabilitation pharmacotherapy and rehabilitation nutrition are important to improve frailty and disability in older people under these circumstances. PMID- 29600127 TI - The diagnostic accuracy of the mediastinal width on supine anteroposterior chest radiographs with nontraumatic Stanford type A acute aortic dissection. AB - Background: Nontraumatic Stanford type A acute aortic dissection is a life threatening condition; thus, the ability to make a precise diagnosis of nontraumatic Stanford type A acute aortic dissection is essential for the emergency physician. Several reports have shown that the mediastinal widening on a chest radiograph is useful for the diagnosis of nontraumatic Stanford type A acute aortic dissection; however, the exact cutoff value of the mediastinal width on plain radiographs is rarely defined. Methods: A single-center retrospective case-control study was conducted between October 1, 2013, and March 31, 2015. We evaluated the maximal mediastinal width of the anteroposterior chest X-ray at the level of the aortic knob in the supine position between patient groups with and without nontraumatic Stanford type A acute aortic dissection. Results: We enrolled 72 patients (36 patients with nontraumatic Stanford type A acute aortic dissection and 36 patients without nontraumatic Stanford type A acute aortic dissection). The median mediastinal width of patients with nontraumatic Stanford type A acute aortic dissection was significantly larger than that of patients without nontraumatic Stanford type A acute aortic dissection (100.7 mm vs 77.7 mm, P < .01). The optimal cutoff level was 87 mm (sensitivity, 81%; specificity, 89%). Using multivariable logistic regression, the odds ratio of a mediastinal width of >87 mm for a diagnosis nontraumatic Stanford type A acute aortic dissection was 57.1 (95% confidence interval, 11.2-290.2). Conclusion: A mediastinal width of >87 mm showed high sensitivity in the diagnosis of probable nontraumatic Stanford type A acute aortic dissection. PMID- 29600128 TI - Fatal necrotizing myositis from fulminant Streptococcus dysgalactiae subspecies equisimilis (SDSE) infection: A case report of autopsy images. AB - Over the past few decades, Streptococcus dysgalactiae subspecies equisimilis (SDSE) have been considered as weak pathogenicity compared with S. pyogenes (GAS). Some recent reports argue that SDSE may bring severe soft tissue infection as same as GAS. No reports have been tried to reveal the clinical characteristics and autopsy images of fulminant SDSE infection. In this case report, we aimed to present a case of fatal necrotizing myositis from fulminant SDSE infection at iliopsoas, including autopsy appearance. PMID- 29600129 TI - Severe pleuritis and pericarditis associated with very-late-onset systemic lupus erythematosus. AB - Systemic lupus erythematosus (SLE) is a multisystem disorder, which occurs mostly in young women. However, late-onset SLE does exist and sometimes presents with an atypical, diversified course. We describe an 85-year-old woman who was admitted to our hospital for lower extremity edema and hand grip weakness. Chest computed tomography scan 4 days after admission demonstrated rapid accumulation of pleural and pericardial effusions, which did not exist on admission. She was diagnosed with pleuritis and pericarditis associated with very-late-onset SLE. Methylprednisolone pulse therapy resulted in a drastic improvement in serositis. Our case exemplifies the fact that patients with late-onset SLE sometimes follow an atypical course, which makes the clinical diagnosis difficult.

PMID- 29600135 TI - Synthesis and characterization of two new TiO2-containing benzothiazole-based imine composites for organic device applications. AB - The effect of the presence of titanium dioxide in two new imines, (E,E)-(butane 1,4-diyl)bis(oxybutane-4,1-diyl) bis(4-{[(benzo[d][1,3]thiazol-2 yl)methylidene]amino}benzoate) (SP1) and (E)-N-[(benzo[d][1,3]thiazol-2 yl)methylidene]-4-dodecylaniline (SP2), on the properties and stability of imine:TiO2 composites for organic device applications were examined. The investigated titanium dioxide (in anatase form, obtained via the sol-gel method) exhibited a surface area of 59.5 m2/g according to Brunauer-Emmett-Teller theory, and its structure is a combination of both meso- and microporous. The average pore diameter calculated by the Barrett-Joyner-Halenda method was 6.2 nm and the cumulative volume of pores was 0.117 m3/g. The imine SP1 exhibited columnar organization (Col), while SP2 revealed a hexagonal columnar crystalline phase (Colhk). The imine:TiO2 mixtures in various weight ratio (3:0, 3:1, 3:2, 3:3) showed a lower energy gap and HOMO-LUMO energy levels compared to pure TiO2. This implies that TiO2 provides not only a larger surface area for sensitizer adsorption and good electron collection, but also causes a shift of the imine energy levels resulting from intermolecular interaction. Also the temperature of the phase transition was slightly affected with the increase of TiO2 concentration in imine-based composites. The changes observed in the Fourier transform middle-infrared absorption (FT-MIR) spectra confirmed the significant influence of TiO2 on structural properties of both investigated imines. Similar interactions of oxygen vacancies existing on the TiO2 surface with SP1 and SP2 were observed. The imine:TiO2 mixtures showed good air stability and reusability, which demonstrates its potential for organic device applications. PMID- 29600136 TI - A review of carbon-based and non-carbon-based catalyst supports for the selective catalytic reduction of nitric oxide. AB - Various types of carbon-based and non-carbon-based catalyst supports for nitric oxide (NO) removal through selective catalytic reduction (SCR) with ammonia are examined in this review. A number of carbon-based materials, such as carbon nanotubes (CNTs), activated carbon (AC), and graphene (GR) and non-carbon-based materials, such as Zeolite Socony Mobil-5 (ZSM-5), TiO2, and Al2O3 supported materials, were identified as the most up-to-date and recently used catalysts for the removal of NO gas. The main focus of this review is the study of catalyst preparation methods, as this is highly correlated to the behaviour of NO removal. The general mechanisms involved in the system, the Langmuir-Hinshelwood or Eley Riedeal mechanism, are also discussed. Characterisation analysis affecting the surface and chemical structure of the catalyst is also detailed in this work. Finally, a few major conclusions are drawn and future directions for work on the advancement of the SCR-NH3 catalyst are suggested. PMID- 29600137 TI - Heavy-metal detectors based on modified ferrite nanoparticles. AB - In this work, we analyze artificial heavy-metal solutions with ferrite nanoparticles. Measurements of adsorption effectiveness of different kinds of particles, pure magnetite or magnetite doped with calcium, cobalt, manganese, or nickel ions, were carried out. A dependence of the adsorption efficiency on the composition of the inorganic core has been observed. Ferrites surfaces were modified by phthalic anhydride (PA), succinic anhydride (SA), acetic anhydride (AA), 3-phosphonopropionic acid (3-PPA), or 16-phosphohexadecanoic acid (16-PHDA) to compare the adsorption capability of the heavy metals Cd, Cu and Pb. The obtained nanoparticles were structurally characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Mossbauer spectroscopy. The amounts of Cd, Cu and Pb were measured out by atomic absorption spectroscopy (AAS) and energy dispersive X-ray (EDX) as comparative techniques. The performed study shows that SA linker appears to be the most effective in the adsorption of heavy metals. Moreover, regarding the influence of the composition of the inorganic core on the detection ability, the most effective ferrite Mn0.5Fe2.5O4 was selected for discussion. The highest heavy-metal adsorption capability and universality was observed for SA as a surface modifier. PMID- 29600138 TI - Surface-plasmon-enhanced ultraviolet emission of Au-decorated ZnO structures for gas sensing and photocatalytic devices. AB - Pure and Au-decorated sub-micrometer ZnO spheres were successfully grown on glass substrates by simple chemical bath deposition and photoreduction methods. The analysis of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, energy-dispersive X-ray spectroscopy (EDS), UV-vis absorption, and photoluminescence (PL) spectra results were used to verify the incorporation of plasmonic Au nanoparticles (NPs) on the ZnO film. Time-resolved photoluminescence (TRPL) spectra indicated that a surface plasmonic effect exists with a fast rate of charge transfer from Au nanoparticles to the sub-micrometer ZnO sphere, which suggested the strong possibility of the use of the material for the design of efficient catalytic devices. The NO2 sensing ability of as deposited ZnO films was investigated with different gas concentrations at an optimized sensing temperature of 120 degrees C. Surface decoration of plasmonic Au nanoparticles provided an enhanced sensitivity (141 times) with improved response (tauRes = 9 s) and recovery time (tauRec = 39 s). The enhanced gas sensing performance and photocatalytic degradation processes are suggested to be attributed to not only the surface plasmon resonance effect, but also due to a Schottky barrier between plasmonic Au and ZnO structures. PMID- 29600139 TI - Valley-selective directional emission from a transition-metal dichalcogenide monolayer mediated by a plasmonic nanoantenna. AB - Background: Two-dimensional (2D) transition-metal dichalcogenides (TMDCs) with intrinsically crystal inversion-symmetry breaking have shown many advanced optical properties. In particular, the valley polarization in 2D TMDCs that can be addressed optically has inspired new physical phenomena and great potential applications in valleytronics. Results: Here, we propose a TMDC-nanoantenna system that could effectively enhance and direct emission from the two valleys in TMDCs into diametrically opposite directions. By mimicking the emission from each valley of the monolayer of WSe2 as a chiral point-dipole emitter, we demonstrate numerically that the emission from different valleys is directed into opposite directions when coupling to a double-bar plasmonic nanoantenna. The directionality derives from the interference between the dipole and quadrupole modes excited in the two bars, respectively. Thus, we could tune the emission direction from the proposed TMDC-nanoantenna system by tuning the pumping without changing the antenna structure. Furthermore, we discuss the general principles and the opportunities to improve the average performance of the nanoantenna structure. Conclusion: The scheme we propose here can potentially serve as an important component for valley-based applications, such as non-volatile information storage and processing. PMID- 29600140 TI - Facile synthesis of a ZnO-BiOI p-n nano-heterojunction with excellent visible light photocatalytic activity. AB - In this paper, an efficient method to produce a ZnO/BiOI nano-heterojunction is developed by a facile solution method followed by calcination. By tuning the ratio of Zn/Bi, the morphology varies from nanoplates, flowers to nanoparticles. The heterojunction formed between ZnO and BiOI decreases the recombination rate of photogenerated carriers and enhances the photocatalytic activity of ZnO/BiOI composites. The obtained ZnO/BiOI heterostructured nanocomposites exhibit a significant improvement in the photodegradation of rhodamine B under visible light (lambda >= 420 nm) irradiation as compared to single-phase ZnO and BiOI. A sample with a Zn/Bi ratio of 3:1 showed the highest photocatalytic activity (~99.3% after 100 min irradiation). The photodegradation tests indicated that the ZnO/BiOI heterostructured nanocomposites not only exhibit remarkably enhanced and sustainable photocatalytic activity, but also show good recyclability. The excellent photocatalytic activity could be attributed to the high separation efficiency of the photoinduced electron-hole pairs as well as the high specific area. PMID- 29600141 TI - Graphene composites with dental and biomedical applicability. AB - Pure graphene in the form of few-layer graphene (FLG) - 1 to 6 layers - is biocompatible and non-cytotoxic. This makes FLG an ideal material to incorporate into dental polymers to increase their strength and durability. It is well known that graphene has high mechanical strength and has been shown to enhance the mechanical, physical and chemical properties of biomaterials. However, for commercial applicability, methods to produce larger than lab-scale quantities of graphene are required. Here, we present a simple method to make large quantities of FLG starting with commercially available multi-layer graphene (MLG). This FLG material was then used to fabricate graphene dental-polymer composites. The resultant graphene-modified composites show that low concentrations of graphene (ca. 0.2 wt %) lead to enhanced performance improvement in physio-mechanical properties - the mean compressive strength increased by 27% and the mean compressive modulus increased by 22%. Herein we report a new, cheap and simple method to make large quantities of few-layer graphene which was then incorporated into a common dental polymer to fabricate graphene-composites which shows very promising mechanical properties. PMID- 29600142 TI - Effect of microtrichia on the interlocking mechanism in the Asian ladybeetle, Harmonia axyridis (Coleoptera: Coccinellidae). AB - The hindwings of beetles are folded under the elytra when they are at rest but are extended during flight, which can provide bioinspiration for the design of deployable micro air vehicles (MAVs). Beetle hindwings must be able to be both securely locked under the elytra and freely extended for flight, depending on the required action. To investigate the locking mechanism, this study used environmental scanning electron microscopy (ESEM) to examine the microstructures of the elytra, hindwings and abdomen of the Asian ladybeetle, Harmonia axyridis (Pallas, 1773). On the ventral side (VS) of the elytra, the microtrichia show a transitional structure from the lateral edge to the medial edge. On the hindwing surface, the folded regions were observed on both the dorsal side (DS) and the VS. On the abdomen, the microtrichia between the abdominal segments show a cyclical change from sparse to dense in each segment in the middle of the abdomen. Furthermore, the different directions of microtrichia that lead to self locking friction on the surfaces of the hindwing, elytron and abdomen appear to facilitate interlocking. A model for the interlocking of the hindwings of the H. axyridis was established, and its underlying mechanism is discussed.

AB - The influence of small ferroelectric BaTiO3 particles on the planar-homeotropic transition threshold voltage in smectic A liquid crystals consisting of p nitrophenyl p-decyloxybenzoate and 4-cyano-4'-pentylbiphenyl were studied by using capacitance-voltage (C-V) measurements. It was shown that the BaTiO3 particles significantly reduce the threshold voltage. The obtained result is explained by two factors: an increase of dielectric anisotropy of the liquid crystals and the formation of a strong electric field near polarized particles of BaTiO3. It was shown that the role of the second factor is dominant. The explanations of some features observed in the C-V characteristics are given. PMID- 29600144 TI - Noble metal-modified titania with visible-light activity for the decomposition of microorganisms. AB - Commercial titania photocatalysts were modified with silver and gold by photodeposition, and characterized by diffuse reflectance spectroscopy (DRS), X ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning transmission electron microscopy (STEM). It was found that silver co-existed in zero valent (core) and oxidized (shell) forms, whereas gold was mainly zero valent. The obtained noble metal-modified samples were examined with regard to antibacterial (Escherichia coli (E. coli)) and antifungal (Aspergillus niger (A. niger), Aspergillus melleus (A. melleus), Penicillium chrysogenum (P. chrysogenum), Candida albicans (C. albicans)) activity under visible-light irradiation and in the dark using disk diffusion, suspension, colony growth ("poisoned food") and sporulation methods. It was found that silver-modified titania, besides remarkably high antibacterial activity (inhibition of bacterial proliferation), could also decompose bacterial cells under visible-light irradiation, possibly due to an enhanced generation of reactive oxygen species and the intrinsic properties of silver. Gold-modified samples were almost inactive against bacteria in the dark, whereas significant bactericidal effect under visible-light irradiation suggested that the mechanism of bacteria inactivation was initiated by plasmonic excitation of titania by localized surface plasmon resonance of gold. The antifungal activity tests showed efficient suppression of mycelium growth by bare titania, and suppression of mycotoxin generation and sporulation by gold-modified titania. Although, the growth of fungi was hardly inhibited through disc diffusion (inhibition zones around discs), it indicates that gold does not penetrate into the media, and thus, a good stability of plasmonic photocatalysts has been confirmed. In summary, it was found that silver-modified titania showed superior antibacterial activity, whereas gold-modified samples were very active against fungi, suggesting that bimetallic photocatalysts containing both gold and silver should exhibit excellent antimicrobial properties. PMID- 29600145 TI - Towards the third dimension in direct electron beam writing of silver. AB - Carboxylates constitute an extremely promising class of precursor compounds for the electron beam induced deposition of silver. In this work both silver 2,2 dimethylbutyrate and silver pentafluoropropionate were investigated with respect to their dwell-time-dependent deposition behavior and growth characteristics. While silver 2,2-dimethylbutyrate showed a strong depletion in the center of the impinging electron beam profile hindering any vertical growth, silver pentafluoropropionate indicated a pronounced dependency of the deposit height on the dwell time. Truly three-dimensional silver structures could be realized with silver pentafluoropropionate. The pillars were polycrystalline with silver contents of more than 50 atom % and exhibit strong Raman enhancement. This constitutes a promising route towards the direct electron beam writing of three dimensional plasmonic device parts from the gas phase. PMID- 29600146 TI - Perfusion double-channel micropipette probes for oxygen flux mapping with single cell resolution. AB - Measuring cellular respiration with single-cell spatial resolution is a significant challenge, even with modern tools and techniques. Here, a double channel micropipette is proposed and investigated as a probe to achieve this goal by sampling fluid near the point of interest. A finite element model (FEM) of this perfusion probe is validated by comparing simulation results with experimental results of hydrodynamically confined fluorescent molecule diffusion. The FEM is then used to investigate the dependence of the oxygen concentration variation and the measurement signal on system parameters, including the pipette's shape, perfusion velocity, position of the oxygen sensors within the pipette, and proximity of the pipette to the substrate. The work demonstrates that the use of perfusion double-barrel micropipette probes enables the detection of oxygen consumption signals with micrometer spatial resolution, while amplifying the signal, as compared to sensors without the perfusion system. In certain flow velocity ranges (depending on pipette geometry and configuration), the perfusion flow increases oxygen concentration gradients formed due to cellular oxygen consumption. An optimal perfusion velocity for respiratory measurements on single cells can be determined for different system parameters (e.g., proximity of the pipette to the substrate). The optimum perfusion velocities calculated in this paper range from 1.9 to 12.5 MUm/s. Finally, the FEM model is used to show that the spatial resolution of the probe may be varied by adjusting the pipette tip diameter, which may allow oxygen consumption mapping of cells within tissue, as well as individual cells at subcellular resolution. PMID- 29600147 TI - Comparative study of antibacterial properties of polystyrene films with TiO x and Cu nanoparticles fabricated using cluster beam technique. AB - Background: Antibacterial materials are of high importance for medicine, and for the production and conservation of food. Among these materials, polymer films with metal nanoparticles (NPs) are of considerable interest for many practical applications. Results: The paper describes a novel approach for the formation of bactericidal polymer thin films (polystyrene in this case), produced by spin coating, with Ti and Cu NPs deposited from cluster beams. Ti NPs are treated in three different ways in order to study different approaches for oxidation and, thus, efficiency in formation of the particles with semiconducting properties required for the catalytic formation of reactive oxygen species. Cu NPs are used as deposited. Partial NP embedding into polystyrene is realised in a controllable manner using thermal annealing in order to improve surface adhesion and make the particles resistant against wash-out. The formed composite films with TiO x and Cu species are tested as bactericidal media using E.coli bacteria as model microorganisms. Conclusion: The obtained results show considerable efficiency in destroying the bacteria and a good possibility of multiple re-use of the same composite films making the suggested approach attractive for the cases requiring reusable polymer-based antibacterial media. PMID- 29600148 TI - Optical orientation of nematic liquid crystal droplets via photoisomerization of an azodendrimer dopant. AB - Two sequential transformations of the orientational structure in nematic liquid crystal droplets containing a dendrimer additive (nanosized macromolecules with light-absorbing azobenzene terminal moieties) under light irradiation in the UV blue spectral range were investigated. The origin of these transitions is in the change of the boundary conditions due to photoisomerization of the dendrimer adsorbed onto the liquid crystal-glycerol interface. It was shown that the photoisomerization processes of dendrimer molecules in a liquid crystal are accompanied by a spatial rearrangement of their azobenzene moieties, which is the key point in the explanation of the observed effects. PMID- 29600149 TI - Facile chemical routes to mesoporous silver substrates for SERS analysis. AB - Mesoporous silver nanoparticles were easily synthesized through the bulk reduction of crystalline silver(I) oxide and used for the preparation of highly porous surface-enhanced Raman scattering (SERS)-active substrates. An analogous procedure was successfully performed for the production of mesoporous silver films by chemical reduction of oxidized silver films. The sponge-like silver blocks with high surface area and the in-situ-prepared mesoporous silver films are efficient as both analyte adsorbents and Raman signal enhancement mediators. The efficiency of silver reduction was characterized by X-ray diffraction and X ray photoelectron spectroscopy. The developed substrates were applied for SERS detection of rhodamine 6G (enhancement factor of about 1-5 * 105) and an anti ischemic mildronate drug (meldonium; enhancement factor of ~102) that is known for its ability to increase the endurance performance of athletes. PMID- 29600150 TI - Effect of annealing treatments on CeO2 grown on TiN and Si substrates by atomic layer deposition. AB - In this work, we investigate the effect of thermal treatment on CeO2 films fabricated by using atomic layer deposition (ALD) on titanium nitride (TiN) or on silicon (Si) substrates. In particular, we report on the structural, chemical and morphological properties of 25 nm thick ceria oxide with particular attention to the interface with the substrate. The annealing treatments have been performed in situ during the acquisition of X-Ray diffraction patterns to monitor the structural changes in the film. We find that ceria film is thermally stable up to annealing temperatures of 900 degrees C required for the complete crystallization. When ceria is deposited on TiN, the temperature has to be limited to 600 degrees C due to the thermal instability of the underlying TiN substrate with a broadening of the interface, while there are no changes detected inside the CeO2 films. As-deposited CeO2 films show a cubic fluorite polycrystalline structure with texturing. Further, after annealing at 900 degrees C an increase of grain dimensions and an enhanced preferential (200) orientation are evidenced. These findings are a strong indication that the texturing is an intrinsic property of the system more than a metastable condition due to the ALD deposition process. This result is interpreted in the light of the contributions of different energy components (surface energy and elastic modulus) which act dependently on the substrate properties, such as its nature and structure. PMID- 29600151 TI - Nanoscale mapping of dielectric properties based on surface adhesion force measurements. AB - The detection of local dielectric properties is of great importance in a wide variety of scientific studies and applications. Here, we report a novel method for the characterization of local dielectric distributions based on surface adhesion mapping by atomic force microscopy (AFM). The two-dimensional (2D) materials graphene oxide (GO), and partially reduced graphene oxide (RGO), which have similar thicknesses but large differences in their dielectric properties, were studied as model systems. Through direct imaging of the samples with a biased AFM tip in PeakForce Quantitative Nano-Mechanics (PF-QNM) mode, the local dielectric properties of GO and RGO were revealed by mapping their surface adhesion forces. Thus, GO and RGO could be conveniently differentiated. This method provides a simple and general approach for the fast characterization of the local dielectric properties of graphene-based materials and will further facilitate their applications in energy generation and storage devices. PMID- 29600152 TI - Bioinspired self-healing materials: lessons from nature. AB - Healing is an intrinsic ability in the incredibly biodiverse populations of the plant and animal kingdoms created through evolution. Plants and animals approach healing in similar ways but with unique pathways, such as damage containment in plants or clotting in animals. After analyzing the examples of healing and defense mechanisms found in living nature, eight prevalent mechanisms were identified: reversible muscle control, clotting, cellular response, layering, protective surfaces, vascular networks or capsules, exposure, and replenishable functional coatings. Then the relationship between these mechanisms, nature's best (evolutionary) methods of mitigating and healing damage, and existing technology in self-healing materials are described. The goals of this top-level overview are to provide a framework for relating the behavior seen in living nature to bioinspired materials, act as a resource to addressing the limitations/problems with existing materials, and open up new avenues of insight and research into self-healing materials. PMID- 29600153 TI - Cyclodextrin inhibits zinc corrosion by destabilizing point defect formation in the oxide layer. AB - Corrosion inhibitors are added in low concentrations to corrosive solutions for reducing the corrosion rate of a metallic material. Their mechanism of action is typically the blocking of free metal surface by adsorption, thus slowing down dissolution. This work uses electrochemical impedance spectroscopy to show the cyclic oligosaccharide beta-cyclodextrin (beta-CD) to inhibit corrosion of zinc in 0.1M chloride with an inhibition efficiency of up to 85%. Only a monomolecular adsorption layer of beta-CD is present on the surface of the oxide covered metal, with Raman spectra of the interface proving the adsorption of the intact beta-CD. Angular dependent X-ray photoelectron spectroscopy (ADXPS) and ultraviolet photoelectron spectroscopy (UPS) were used to extract a band-like diagram of the beta-CD/ZnO interface, showing a large energy level shift at the interface, closely resembling the energy level alignment in an n-p junction. The energy level shift is too large to permit further electron transfer through the layer, inhibiting corrosion. Adsorption hence changes the defect density in the protecting ZnO layer. This mechanism of corrosion inhibition shows that affecting the defect chemistry of passivating films by molecular inhibitors maybe a viable strategy to control corrosion of metals. PMID- 29600154 TI - Scanning speed phenomenon in contact-resonance atomic force microscopy. AB - This work presents data confirming the existence of a scan speed related phenomenon in contact-mode atomic force microscopy (AFM). Specifically, contact resonance spectroscopy is used to interrogate this phenomenon. Above a critical scan speed, a monotonic decrease in the recorded contact-resonance frequency is observed with increasing scan speed. Proper characterization and understanding of this phenomenon is necessary to conduct accurate quantitative imaging using contact-resonance AFM, and other contact-mode AFM techniques, at higher scan speeds. A squeeze film hydrodynamic theory is proposed to explain this phenomenon, and model predictions are compared against the experimental data.

PMID- 29600156 TI - Comparative study of sculptured metallic thin films deposited by oblique angle deposition at different temperatures. AB - Metals with a wide range of melting points are deposited by electron beam evaporation under oblique deposition geometry on thermally oxidized Si substrates. During deposition the sample holder is cooled down to 77 K. It is observed that all obliquely deposited metals grow as tilted, high aspect ratio columns and hence with a similar morphology. A comparison of such columns with those deposited at room temperature (300 K) reveals that shadowing dominates the growth process for columns deposited at 77 K, while the impact of surface diffusion is significantly increased at elevated substrate temperatures. Furthermore, it is discussed how the incidence angle of the incoming particle flux and the substrate temperature affect the columnar tilt angles and the porosity of the sculptured thin films. Exemplarily for tilted Al columns deposited at 77 K and at 300 K, in-plane pole figure measurements are carried out. A tendency to form a biaxial texture as well as a change in the crystalline structure depending on the substrate temperature is found for those films. PMID- 29600157 TI - Electro-optical interfacial effects on a graphene/pi-conjugated organic semiconductor hybrid system. AB - The influence of graphene and retinoic acid (RA) - a pi-conjugated organic semiconductor - interface on their hybrid system is investigated. The physical properties of the interface are assessed via scanning probe microscopy, optical spectroscopy (photoluminescence and Raman) and ab initio calculations. The graphene/RA interaction induces the formation of a well-organized pi-conjugated self-assembled monolayer (SAM) at the interface. Such structural organization leads to the high optical emission efficiency of the RA SAM, even at room temperature. Additionally, photo-assisted electrical force microscopy, photo assisted scanning Kelvin probe microscopy and Raman spectroscopy indicate a RA induced graphene doping and photo-charge generation. Finally, the optical excitation of the RA monolayer generates surface potential changes on the hybrid system. In summary, interface-induced organized structures atop 2D materials may have an important impact on both design and operation of pi-conjugated nanomaterial-based hybrid systems. PMID- 29600158 TI - Toxicity and Applications of Internalised Magnetite Nanoparticles Within Live Paramecium caudatum Cells. AB - The nanotechnology revolution has allowed us to speculate on the possibility of hybridising nanoscale materials with live substrates, yet significant doubt still remains pertaining to the effects of nanomaterials on biological matter. In this investigation, we cultivate the ciliated protistic pond-dwelling microorganism Paramecium caudatum in the presence of excessive quantities of magnetite nanoparticles in order to deduce potential beneficial applications for this technique, as well as observe any deleterious effects on the organisms' health. Our findings indicate that this variety of nanoparticle is well-tolerated by P. caudatum cells, who were observed to consume them in quantities exceeding 5-12% of their body volume: cultivation in the presence of magnetite nanoparticles does not alter P. caudatum cell volume, swimming speed, growth rate or peak colony density and cultures may persist in nanoparticle-contaminated media for many weeks. We demonstrate that P. caudatum cells ingest starch-coated magnetite nanoparticles which facilitates their being magnetically immobilised whilst maintaining apparently normal ciliary dynamics, thus demonstrating that nanoparticle biohybridisation is a viable alternative to conventional forms of ciliate quieting. Ingested magnetite nanoparticle deposits appear to aggregate, suggesting that (a) the process of being internalised concentrates and may therefore detoxify (i.e. render less reactive) nanomaterial suspensions in aquatic environments, and (b) P. caudatum is a candidate organism for programmable nanomaterial manipulation and delivery. PMID- 29600159 TI - Immunosuppressant Peptide Abu-TGIRIS-Abu-NH2 and its Application for Treatment of Multiple Sclerosis. AB - Immunosuppressant peptide immunocortin for the first time was described in 1993. It corresponds to residues 11-20 of human Ig heavy chain (conserved motif of VH domain). There are no data about production of immunocortin by proteolysis of Ig in vivo. Synthetic immunocortin in concentration ~ 10-9 M suppresses phagocytosis in peritoneal macrophages, ConA-dependent blast transformation of rat lymphocytes, exhibits ACTH-like neurotropic activity and was suggested as a potential drug for treatment of a multiple sclerosis (MS). Here, we report a sequence and method of synthesis of Abu-TGIRIS-Abu-NH2 (Abu, alpha-aminobutyric acid), an artificial analogue of immunocortin. Biological trials of peritoneally injected Abu-TGIRIS-Abu-NH2 gave an evidence of its better efficacy versus immunocortin in a test for suppression of the experimental autoimmune encephalomyelitis (EAE) in Dark Agouti (DA) rats.

AB - Purpose of Review: Recent developments in regenerative medicine have precipitated the need to expand gene-modified human T cells to numbers that exceed the capacity of well-plate-based, and flask-based processes. This review discusses the changes in process development that are needed to meet the cell expansion requirements by utilizing hollow-fiber bioreactors. Maintenance of cell proliferation over long periods can become limited by unfilled demands for nutrients and oxygen and by the accumulation of waste products in the local environment. Recent Findings: Perfusion feeding, improved gas exchange, and the efficient removal of lactate can increase the yield of T cells from an average of 10.8E +09 to more than 28E +09 in only 10 days. Summary: Aggressively feeding cells and actively keeping cells in the bioreactor improves gas exchange and metabolite management over semi-static methods. The ability to remove the environmental constraints that can limit cell expansion by using a two-chamber hollow-fiber bioreactor will be discussed.

AB - Purpose of Review: Considerable progress has been made in the field of stem cell research; nonetheless, the use of stem cells for regenerative medicine therapies, for either endogenous tissue repair or cellular grafts post injury, remains a challenge. To better understand how to maintain stem cell potential in vivo and promote differentiation ex vivo, it is fundamentally important to elucidate the interactions between stem cells and their surrounding partners within their distinct niches. Recent Findings: Among the vast array of proteins depicted as mediators for cell-to-cell interactions, connexin-comprised gap junctions play pivotal roles in the regulation of stem cell fate both in vivo and in vitro. Summary: This review summarizes and illustrates the current knowledge regarding the multifaceted roles of Cx43, specifically, in various stem cell niches. PMID- 29600162 TI - Fetal Mesenchymal Stromal Cells: an Opportunity for Prenatal Cellular Therapy. AB - Purpose of Review: The aim of the study is to provide an overview on the possibility of treating congenital disorders prenatally with mesenchymal stromal cells (MSCs). Recent Findings: MSCs have multilineage potential and a low immunogenic profile and are immunomodulatory and more easy to expand in culture. Their ability to migrate, engraft and differentiate, or act via a paracrine effect on target tissues makes MSCs candidates for clinical therapies. Fetal and extra-fetal MSCs offer higher therapeutic potential compared to MSCs derived from adult sources. Summary: MSCs may be safely transplanted prenatally via ultrasound guided injection into the umbilical cord. Due to these characteristics, fetal MSCs are of great interest in the field of in utero stem cell transplantation for treatment of congenital disease. PMID- 29600164 TI - From discourse to practice: the circulation of norms, ideas and practices of migration management through the implementation of the mobility partnerships in Moldova and Georgia. AB - This research wishes to contribute to the understanding of the migration policy regime of the European Union (EU), by considering an analytical perspective that privileges the standpoint of the countries of its neighbourhood. As an entry point, we have focused our analysis on the Mobility Partnership, a policy instrument of soft power, representative of the emblematic network governance privileged by the EU in its current political framework, the Global Approach to Migration and Mobility (GAMM). Applying an "instrument approach", our research raises the question of the role played by the Mobility Partnership in the circulation of norms, ideas and practices related to the "good governance" of international migration, and whether these are internalized by the partner third countries. We present the results of a comparative analysis of two study-cases, Moldova and Georgia, countries considered by the European Commission as the "best pupils" in the implementation of their Mobility Partnerships, with the ambition to interrogate whether this instrument leads to a "common understanding" between the EU and the national actors that may lead to a translation of the European objectives in the field of migration into the registries of practices in the countries of the Eastern neighbourhood. Lastly, we will discuss the strategic "usage" of this instrument from the partner third countries, that can lead to different results, from complete absorption of the objectives, to resistance in their implementation. PMID- 29600163 TI - The Role of Steroid Hormones in Breast and Effects on Cancer Stem Cells. AB - Purpose of Review: This review will discuss how the steroid hormones, estrogen and progesterone, as well as treatments that target steroid receptors, can regulate cancer stem cell (CSC) activity. The CSC theory proposes a hierarchical organization in tumors where at its apex lies a subpopulation of cancer cells endowed with self-renewal and differentiation capacity. Recent Findings: In breast cancer (BC), CSCs have been suggested to play a key role in tumor maintenance, disease progression, and the formation of metastases. In preclinical models of BC, only a few CSCs are required sustain tumor re-growth, especially after conventional anti-endocrine treatments. CSCs include therapy-resistant clones that survive standard of care treatments like chemotherapy, irradiation, and hormonal therapy. Summary: The relevance of hormones for both normal mammary gland and BC development is well described, but it was only recently that the activities of hormones on CSCs have been investigated, opening new directions for future BC treatments and CSCs.

AB - AIM: To investigate the effects and mechanism of miR-211 in mediating the antioxidant function of lens epithelial cells affected by age-related cataracts. METHODS: Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect miR-211 expression in the anterior lens capsules of healthy people, the anterior lens capsules of patients with age-related cataracts, and human epithelial cell line (SRA01/04) cells exposed to oxidative stress. A 2', 7' dichloro-fluorescein diacetate (DCFH-DA) probe was used to measure the levels of endogenous reactive oxygen species (ROS) in human lens epithelial cells (hLECs) exposed to 400 umol/L H2O2 for 1h. SRA01/04 cells were transfected with either miR-211 mimics, mimic controls, miR-211 inhibitors or inhibitor controls. After 72h, these cells were exposed to 400 umol/L H2O2 for 1h, then p53 and Bax mRNA expression were measured using RT-qPCR. p53 and Bax protein expression were also measured by Western blotting analysis. Finally, cell viability was assessed using an MTS assay. RESULTS: Compared to the control group, expression of miR-211 in the anterior lens capsules of age-related cataract patients and in SRA01/04 cells exposed to oxidative stress was significantly increased (P<0.001). Levels of endogenous ROS were significantly elevated in hLECs exposed to oxidative stress (P<0.001). Compared to the mimic control group, the hLECs in the miR-211 mimic group expressed significantly higher levels of p53 and Bax mRNA and protein while cell viability was significantly reduced (P<0.001). Conversely, p53 and Bax mRNA and protein expression were significantly reduced in the miR-211 inhibitor group as compared to the control group, while the cells in this group had much higher levels of cell viability (P<0.001). CONCLUSION: miR-211 is upregulated in the anterior lens capsules of age-related cataract patients. miR-211 decreased the antioxidative stress capacity of lens epithelial cells by upregulating p53 and Bax, while inhibiting cell proliferation and repair. This finding suggests that miR-211 may play a key role in the development of age-related cataracts. PMID- 29600166 TI - Scleral ultrastructure and biomechanical changes in rabbits after negative lens application. AB - AIM: To address the microstructure and biomechanical changes of the sclera of rabbits after negative lens application by spectacle frame apparatus. METHODS: Five New Zealand rabbits of seven weeks post-natal were treated with -8 D lens monocularly over the course of two weeks. Refractive errors and axial length (AXL) were measured at the 1st, 7th and 14th days of the induction period. Ultrastructure of sclera was determined with electron microscopy. Biomechanical properties were tested by an Instron 5565 universal testing machine. RESULTS: Lens-induced (LI) eyes elongated more rapidly compared with fellow eyes with AXL values of 15.56+/-0.14 and 15.21+/-0.14 mm (P<0.01). Fibril diameter was significantly smaller in the LI eyes compared with control ones in the inner, middle, and outer layers (inner layer, 63.533 vs 76.467 nm; middle layer, 92.647 vs 123.984 nm; outer layer, 86.999 vs 134.257 nm, P<0.01, respectively). In comparison with control eyes, macrophage-like cells that engulfed fibroblasts, dilated endoplasmic reticulum, and vacuoles in fibroblasts were observed in the inner and middle stroma in the LI eyes. Ultimate stress and Young's modulus were lower in the LI eyes compared with those in the control eyes. CONCLUSION: Negative lens application alters eye growth, and results in axial elongation with changes in scleral ultrastructural and mechanical properties. PMID- 29600167 TI - Protective effects of a composition of Chinese herbs-Gurigumu-13 on retinal ganglion cell apoptosis in DBA/2J glaucoma mouse model. AB - AIM: To explore the concrete mechanism of a Mongolian compound medicine-Gurigumu 13 (GRGM) for glaucoma treatment. METHODS: DBA/2J mice, as glaucoma models, were intragastric administrated with GRGM to study the effect of GRGM on retinal ganglion cells (RGCs). The loss of RGCs was evaluated with the number of RGCs and axons. The expression of the target protein of RGCs or mouse retinas was determined by Western blot. The relative content of malondialdehyde (MDA) was examined by ELISA assay. RESULTS: GRGM distinctly improved retina damage via increasing the number of neurons, RGCs and axons in a concentration dependent manner. Meanwhile, GRGM obviously decreased the high level of MDA and the expression of oxidative stress-related proteins in retinas of DBA/2J mice, but promoted the expression of antioxidant proteins. Additionally, GRGM also significantly inhibited the protein expression of Bip and Chop, which were markers of endoplasmic reticulum stress-induced apoptosis. CONCLUSION: GRGM have obvious protective effects on RGCs in DBA/2J mice, and increase the number of RGCs and axons via inhibiting oxidative stress and endoplasmic reticulum stress. PMID- 29600168 TI - A recurrent G367R mutation in MYOC associated with juvenile open angle glaucoma in a large Chinese family. AB - AIM: To identify the mutations of MYOC, OPTN, CYP1B1 and WDR36 in a large Chinese family affected by juvenile open angle glaucoma (JOAG). METHODS: Of 114 members of one family were recruited in this study. Blood samples from twelve members of this pedigree were collected for further research. As a control, 100 unrelated subjects were recruited from the same hospital. The exon and flanking intron sequences of candidate genes were amplified using the polymerase chain reaction and direct DNA sequencing. RESULTS: The proband (III:10) was a seventy-three years old woman with binocular JOAG at the age of 31. A recurrent heterozygous mutation (c.1099G>A) of MYOC was identified in the three JOAG patients and another suspect. This transition was located in the first base pair of codon 367 (GGA>AGA) in exon 3 of MYOC and was predicted to be a missense substitution of glycine to arginine (p.G367R) in myocilin. Mutations in OPTN, CYP1B1 or WDR36 were not detected in this study. The G367R mutation was not present in unaffected family members or in 100 ethnically matched controls. Other variants of the coding regions of candidate genes were not detected in all participants. To date, this family was the largest to have been identified as carrying a certain MYOC mutation in China, further evidence of a founder effect for the G367R MYOC mutant was provided by our data. CONCLUSION: A MYOC c.1099G>A mutation in an autosomal dominant JOAG family is identified and the characteristic phenotypes among the patients are summarized. Genetic testing could be utilized in high-risk populations and be helpful not only for genetic counseling, but also for early diagnosis and treatment of affected patients or carriers of inherited JOAG. PMID- 29600169 TI - Mechanism of retinal pericyte migration through Angiopoietin/Tie-2 signaling pathway on diabetic rats. AB - AIM: To investigate the mechanism of pericyte migration through Angiopoietin-2 (Ang-2)/Tie-2 signaling pathway. METHODS: We divided the rats into 5 groups. Each diabetic rat model groups injected with Tie-2 inhibitor, ERK1/2 inhibitor, Akt/PKB inhibitor, and DMSO intravitreal. Retinal digest preparation was done to examine the retinal vasculature including pericyte: endothelial ratio, and morphology of pericyte migration. Tie-2, ERK1/2 and Akt/PKB phosporylation were analyzed by confocal laser scanning microscopy. RESULTS: There was a correlation between pericyte migration with increasing Ang-2 (P<0.05). Pericyte number reduced by 40% (1:2.4) after 5wk diabetes on diabetic rats. The pericyte: endothelial ratio on group with Tie-2 inhibitor were 1:1.8. The same result shows on group with Akt/PKB inhibition. ERK1/2 inhibitor group shows the best results of pericyte: endothelial ratio (1:1.7). Inhibition on Tie-2 receptor decreased the phosphorylation activity of Tie-2, ERK1/2 and Akt/PKB pathway. ERK1/2 inhibition also decreasing the phosphorylation of Tie-2 and Akt/PKB. But on Akt/PKB inhibition, the phosphorylation of Tie-2 and ERK1/2 were relative the same. CONCLUSION: Ang-2 has a role for pericyte migration on diabetic rats through Tie-2 receptor, ERK1/2 and Akt/PKB pathways. ERK1/2 is a dominant pathway based on the ability to supress another pathway activity and decreasing pericyte migration on diabetic rats. PMID- 29600170 TI - Is Marcus Gunn jaw winking a primitive reflex? Rat neuroanatomy. AB - AIM: To investigate a possible trigeminal proprioceptive-oculomotor neural pathway and explore possible synaptic connections between neurons in this pathway. Attempt to bring a new insight to mechanism of Marcus Gunn syndrome (MGS). METHODS: Anterograde and retrograde tract tracing was applied and combined with immunofluorescent stain in rats. After electrophysiological identifying mesencephalic trigeminal nucleus (Vme) neurons, intracellular injection of tracer was performed to trace axon trajectory. RESULTS: Following injections of anterograde tracers into the Vme, labeled terminals were observed ipsilateral in oculomotor and trochlear nuclei (III/IV), as well as in their premotor neurons in interstitial nucleus of Cajal and Darkschewitsch nucleus (INC/DN). Combining with choline acetyltransferase (ChAT) immunofluorescent stain, it showed that Vme projecting terminals contact upon ChAT positive III/IV motoneurons under confocal microscope. By retrograde labeling premotor neurons of the III, it showed that Vme neuronal terminals contact with retrogradely labeled pre-oculomotor neurons in the INC/DN. Axons of intracellularly labeled Vme neurons that respond to electric stimuli of the masseter nerve traveled into the ipsilateral III. CONCLUSION: There may exist a trigeminal proprioceptive-oculomotor system neural circuit in the rat, which is probably related to vertical-torsional eye movements. Possible association of this pathway with MGS etiology was discussed. PMID- 29600171 TI - Low concentration of sodium hyaluronate temporarily elevates the tear film lipid layer thickness in dry eye patients with lipid deficiency. AB - AIM: To investigate the effects of different concentrations of artificial tears on lipid layer thickness (LLT) and blink rate (BR) in dry eye patients. METHODS: This study included 106 eyes of 58 patients with dry eye. The lipid deficiency type was defined as the LLT baseline <75 nm. The LLT and BR were measured at baseline and 1, 5 and 15min after the instillation of 0.1% or 0.3% sodium hyaluronate (SH) eye drops by using the LipiView ocular surface interferometer. RESULTS: In the lipid deficiency group, the LLT increased from baseline at 1min post instillation. The LLT after the instillation of 0.1% SH was significantly higher than that after the instillation of 0.3% SH (P<0.001). The LLT returned to baseline at 15min post instillation of 0.1% SH and at 5min post instillation of 0.3% SH. In the non-lipid deficiency group, the LLT decreased from baseline at 1min and returned to baseline at 5min for both treatments. The BRs were not significantly different at different time points for both treatments. CONCLUSION: SH eye drops induce a short-term increase in LLT of patients with lipid deficiency. A low concentration of artificial tears have a stronger effect than a high concentration of artificial tears on the increase in LLT. In comparison, SH eye drops induce a transient and slight decrease in LLT of patients without lipid deficiency. A low concentration of artificial tears might be better for patients with lipid deficiency. PMID- 29600172 TI - Clinical outcome of combined conjunctival autograft transplantation and amniotic membrane transplantation in pterygium surgery. AB - AIM: To compare long-term outcome of primary and recurrent pterygium surgery with three different techniques: combined conjunctival autograft and overlay amniotic membrane transplantation (CAT with AMT), conjunctival autograft transplantation (CAT) alone and amniotic membrane transplantation (AMT) alone. METHODS: In this retrospective study, 142 eyes of 142 pterygium patients (104 primary, 38 recurrent) who underwent CAT (group A), AMT (group B) or CAT with AMT (group C) respectively following surgical excision were reviewed and compared based on the recurrences and post-operative complications. RESULTS: The number of recurrence post-surgery were 17 (9 from primary, 8 from recurrent; the same description below), 18 (10, 8) and 2 (1, 1) in groups A, B, and C respectively; dry eyes were 22 (16, 6), 27 (18, 9) and 7 (3, 4); conjunctival inflammations were 30 (17, 13), 27 (16, 11) and 11 (6, 5). Patients in group C (either primary or recurrent or both) mainly showed significantly better results than those in group A or B (P<0.05) regarding above-mentioned clinical effects. CONCLUSION: Combined CAT and overly AMT have significantly lower rates of recurrence and postoperative complications for primary and recurrent pterygium surgery than CAT or AMT alone. PMID- 29600173 TI - Human lens epithelial cell apoptosis and epithelial to mesenchymal transition in femtosecond laser-assisted cataract surgery. AB - AIM: To evaluate human lens epithelium cell apoptosis and epithelial to mesenchymal transition (EMT) induced by femtosecond laser in femtosecond laser assisted cataract surgery (FLACS). METHODS: Sixty cataract patients with N2 to N3 stage according to the LOCS III were enrolled in this study and divided into three groups randomly: FLACS1 group (cataract surgery by FLACS with LenSx), FLACS2 group (cataract surgery by FLACS with LensAR) and manual group (cataract surgery by phacoemulsification). Patients in two FLACS groups performed anterior capsulotomy by LenSx or LensAR laser system. Patients in the manual group were performed continuous curvilinear capsulorrhexis (CCC) manually. The anterior capsules were fixed right after moved out of eye. Hematoxylin-eosine staining, immunofluorescence staining and real-time PCR were performed in order to observe human lens epithelium cells changes after cataract surgery. RESULTS: The capsule cutting edge was shown irregularity and roughness in two FLACS groups and smooth edge in manual capsulotomy by pathologic staining. Irregularities of the cell configuration with partly swollen and destroyed nuclei were observed in two FLACS groups. Femtosecond laser could induce a significantly higher cell apoptosis in human lens epithelium cell than manually performed CCC (P<0.05). Lens epithelium cells apoptosis were correlated with femtosecond laser duration according to Pearson correlation analysis. Decreased N-cadherin expression, alpha-SMA and FSP 1 level in two FLACS groups showed the inhibition of cell EMT. CONCLUSION: Femtosecond laser may affect the apoptosis and EMT of lens epithelium cells which are under the peeled central lens capsule. PMID- 29600174 TI - Outcomes of transconjunctival sutureless 27-gauge vitrectomy for vitreoretinal diseases. AB - AIM: To evaluate the safety and efficacy profile of 27-gauge (27G) pars plana vitrectomy (PPV) for the treatment of various vitreoretinal diseases. METHODS: The clinical outcomes of 61 eyes (58 patients) with various vitreoretinal diseases following 27G PPV were retrospectively reviewed. RESULTS: Surgical indications included rhegmatogenous retinal detachment (n=24), full-thickness macular hole (n=12), diabetic retinopathy (n=11), vitreous hemorrhage (n=6), Eales disease (n=4), pathological myopia-related vitreous floater (n=2), and macular epiretinal membrane (n=2). The mean follow-up was 166.4+/-61.3d (range 98 339d). The mean logMAR best-corrected visual acuity (BCVA) improved from 1.7+/ 1.1 [0.02 decimal visual acuity (VA) equivalent] preoperatively to 1.2+/-1.0 (0.06 decimal VA equivalent) at the last postoperative visit (P<0.001). The mean operative time was 49.9min. With the exception of complicated cataract in one eye, no intraoperative complications were encountered. No case required conversion to conventional 20-, 23- or 25G instrumentation in all surgical maneuvers except for silicone oil infusion, which required a 25G oil injection syringe. Postoperative complications included transient ocular hypertension, vitreous hemorrhage, persistent intraocular pressure elevation, subconjunctival oil leakage, and recurrent retinal detachment. No cases of hypotony, endophthalmitis, and sclerotomy-related tears were observed. CONCLUSION: The current results suggest that 27G PPV system is a safe and effective treatment for various vitreoretinal diseases. When learning to perform 27G PPV, surgeons may encounter a learning curve and should gradually expand surgical indications from easy to pathologically complicated cases. PMID- 29600175 TI - Long-term results of Ahmed glaucoma valve implantation in Egyptian population. AB - AIM: To evaluate the long-term results and complications of Ahmed glaucoma valve (AGV) implantation in a cohort of Egyptian patients. METHODS: A retrospective study of 124 eyes of 99 patients with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 5y was performed. All patients underwent complete ophthalmic examination and intraocular pressure (IOP) measurement before surgery and at 1d, weekly for the 1st month, 3, 6mo, and 1y after surgery and yearly afterward for 5y. IOP was measured by Goldmann applanation tonometry and/or Tono-Pen. Complications and the number of anti glaucoma medications needed were recorded. Success was defined as IOP less than 21 mm Hg with or without anti-glaucoma medication and without additional glaucoma surgery. RESULTS: Mean age was 23.1+/-19.9y. All eyes had at least one prior glaucoma surgery. IOP was reduced from a mean of 37.2+/-6.8 to 19.2+/-5.2 mm Hg after 5y follow-up with a reduced number of medications from 2.64+/-0.59 to 1.81+/-0.4. Complete and qualified success rates were 31.5% and 46.0% respectively at the end of follow-up. The most common complications were encapsulated cyst formation in 51 eyes (41.1%), complicated cataract in 9 eyes (7.25%), recessed tube in 8 eyes (6.45%), tube exposure in 6 eyes (4.8%) and corneal touch in 6 eyes (4.8%). Other complications included extruded AGV, endophthalmitis and persistent hypotony. Each of them was recorded in only 2 eyes (1.6%). CONCLUSION: Although refractory glaucoma is a difficult problem to manage, AGV is effective and relatively safe procedure in treating refractory glaucoma in Egyptian patients with long-term follow-up. Encapsulated cyst formation was the most common complication, which limits successful IOP control after AGV implantation. However, effective complications management can improve the rate of success. PMID- 29600176 TI - Automatic localization of macular area based on structure label transfer. AB - AIM: To explore feasibility and practicability of macula localization independent of macular morphological features. METHODS: A novel method was proposed to identify macula in fundus images by using structure label transfer. Its main idea was to match a processed image with the candidate images with known structures, and then transfer the structure label representing the macular to the processed image as a result of macula localization. In this way, macula localization couldn't be influenced by lesion or other interference any more. RESULTS: The average success rate in four datasets was 98.18%. For accuracy, the average error distance in four datasets was 0.151 optic disc diameter (ODD). Even for severe lesion images, the proposed method can still maintain high success rate and high accuracy, e.g., 95.65% and 0.124 ODD in the case of STARE dataset, respectively, which indicated that the proposed method was highly robust and stable in the complicated situations. CONCLUSION: The proposed method can avoid the interference of lesion to macular morphological features in macula localization, and can locate macula with high accuracy and robustness, verifying its feasibility. PMID- 29600177 TI - Intravitreal anti-VEGF agents, oral glucocorticoids, and laser photocoagulation combination therapy for macular edema secondary to retinal vein occlusion: preliminary report. AB - AIM: To evaluate the efficacy and safety of combined anti-vascular endothelial growth factor (VEGF) agents, oral glucocorticoid, and laser photocoagulation therapy for macular edema (ME) secondary to retinal vein occlusion (RVO). METHODS: This study included 16 eyes of 16 patients with RVO-associated ME. Patients were initially treated with oral prednisone and an intravitreal anti VEGF agent. Two weeks later, patients underwent standard laser photocoagulation. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), and retinal vessel oxygenation were examined over 12mo. RESULTS: Patients received 1.43+/ 0.81 anti-VEGF injections. Mean baseline and 12-month logMAR BCVA were 0.96+/ 0.51 (20/178) and 0.31+/-0.88 (20/40), respectively, in eyes with central retinal vein occlusion (CRVO) (P<0.00), and 1.02+/-0.45 (20/209) and 0.60+/-0.49 (20/80), respectively, in eyes with branch retinal vein occlusion (BRVO) (P<0.00). At 12mo, CRT had significantly decreased in eyes with CRVO (P<0.00) and BRVO (P<0.00). Venous oxygen saturation had significantly increased in eyes with CRVO (P<0.00) and BRVO (P<0.00). No examined parameters were significantly different between the 2 RVO groups. No serious adverse effects occurred. CONCLUSION: Anti VEGF, glucocorticoid, and photocoagulation combination therapy improves visual outcome, prolongs therapeutic effect, and reduces the number of intravitreal injections in eyes with RVO-associated ME. PMID- 29600178 TI - The optic nerve head perfusion and its correlation with the macular blood perfusion in unilateral idiopathic macular hole: an optical coherence tomography angiography study. AB - AIM: To compare the optic nerve head (ONH) perfusion in both eyes of unilateral idiopathic macular hole (IMH) with normal control group by using optical coherence tomography angiography (OCTA) and investigate its correlationship with the macular blood perfusion. METHODS: We performed a prospective and cross sectional study that included 19 patients with full-thickness unilateral IMH and 24 age- and sex-matched controls. All participants received OCTA test. The ONH perfusion was evaluated by the regions of peripapillary and whole en face (the sum of peripapillary and optic disc). The potential correlationship between ONH and parafovea were implied. All the data were performed using the nonparametric test. RESULTS: The mean values of ONH presented that normal control >IMH >unaffected eyes. A statistical variation was found between three groups in the region of temporal (P=0.007). Vessel density notablely decreased on the layers of superficial, deep and choroid of parafovea region in IMH group. The correlative coefficients showed that respectively whole en face and deep retina: r=0.528, peripapillary and deep retina: r=0.525, whole en face and choriocapillaries: r=0.569, peripapillary and choriocapillaries: r=0.504. CONCLUSION: Our study demonstrate a reduced ONH vessel density in both eyes of IMH patients and the vessel density of ONH in IMH eyes are positively correlated with both the retina capillary and choriocapillary in parafoveal. The reduction of vessel densities may indicate the hypoperfusion in IMH eyes. PMID- 29600179 TI - Safety and efficacy of posterior sub-Tenon's carboplatin injection versus intravitreal melphalan therapy in the management of retinoblastoma with secondary vitreous seeds. AB - AIM: To evaluate the safety and efficacy of posterior sub-Tenon's carboplatin injection compared to intravitreal melphalan injection in the management of retinoblastoma (RB) with secondary vitreous seeds. The outcome measures were vitreous seeds regression, need for other treatment modalities to achieve ocular salvage and treatment side effects. METHODS: A prospective interventional comparative nonrandomized study included RB eyes developed secondary vitreous seeds during the period of follow up. They subdivided into two groups: study group I where posterior sub-Tenon's carboplatin (20 mg/2 mL) was injected and study group II where intravitreal melphalan (20 ug /0.1 mL) was injected. The injections repeated every 2-4wk. RESULTS: Thirty-three eyes were included in the study. Seventeen eyes (16 patients) in study group I and 16 eyes (16 patients) in study group II. Ten eyes (30.3%) were completely salvaged following local chemotherapies. Ocular salvage was 23.5% following posterior sub-Tenon's carboplatin injection versus 37.5% following intravitreal melphalan raised to 47.1% and 75% with addition of external beam radiotherapy (EBR) with no statistically significant difference between the study groups (P=0.16). A statistically significant correlation was found between ocular salvage rate and type of vitreous seeds either dust, spheres and clouds (r=0.42, P=0.015) and eyes harbor new solid tumor growth (r=0.35, P=0.045). The mean and median follow up periods following local chemotherapy injections were 2.0y in the study group I and 2.37y in the study group II. Few complications were reported: periorbital edema in all eyes and ocular motility disturbances in 13 eyes (76.5%) following posterior sub-Tenon's carboplatin injection. Vitreous hemorrhage developed in 2 eyes (12.5%) and localized retinopathy in 5 eyes (31.25%) following intravitreal melphalan. CONCLUSION: Local chemotherapy for treatment of RB with secondary vitreous seeds is safe and can salvage 30.3% of eyes without EBR. There is a superiority of intravitreal melphalan in ocular salvage however, no statistically significant difference between both groups. PMID- 29600180 TI - Cap morphology after small-incision lenticule extraction and its effects on intraocular scattering. AB - AIM: To investigate cap morphology after small-incision lenticule extraction (SMILE) and its effects on intraocular scattering. METHODS: Sixty-five eyes of 33 patients undergoing SMILE were enrolled. In addition to regular evaluation, Fourier-domain optical coherence tomography was used to investigate cap thickness at 1d, 1wk, 1 and 3mo postoperatively. The optical quality including modulation transfer function cutoff frequency, Strehl ratio, Optical Quality Analysis System (OQAS) values, and objective scattering index (OSI), were evaluated using OQASTM. RESULTS: Cap thickness decreased from 1d to 1wk (P<0.001), but remained higher than intended thickness of 120 um after 3mo (P<0.001). Cap thickness in central area was thinner than that of in the paracentral and peripheral areas (P<0.0001). Total number of microdistortions decreased from 1d to 3mo (P<0.0001). Pearson analysis revealed a weak correlation between OSI and standard deviation of cap thickness at 1d and 1mo, as well as between range of cap thickness and OSI at 1mo. No correlation was found between microdistortion and OSI, but a negative correlation existed between microdistortion and range at 1d and 1moafter surgery. CONCLUSION: The corneal cap tends to be more accurate and regular with time lapse. Better cap morphology tends to contribute less intraocular scattering in the eyes undergoing SMILE. PMID- 29600181 TI - Visual quality assessment after presbyopic laser in-situ keratomileusis. AB - AIM: To assess visual quality after presbyopia correction using an aspheric ablation profile and a micro-monovision protocol. METHODS: This is a retrospective interventional study. Fifty-four eyes of 27 patients (mean age, 50.2+/-7.5y) who underwent presbyopia correction with an aspheric micro monovision protocol were enrolled. The values of modulation transfer function (MTF) cutoff frequency, Strehl ratio, objective scattering index (OSI) and accommodation range were quantitatively assessed using the HD analyzer. Preoperative and postoperative contrast sensitivity (CS) at far (2.5 m) and near (40 cm) distance and higher-order aberrations (HOAs) were analyzed. Subjective visual satisfaction was evaluated by self-reported questionnaire regarding optical visual symptoms. RESULTS: One year after presbyopia correction, no significant differences were found in the MTF cutoff frequency, Strehl ratio and OSI, however, the HD analyzer accommodation range significantly differed postoperatively (P=0.004). Postoperative CS at 12 and 18 cpd at near showed statistically significant improvement (P=0.020 and 0.008, respectively). Visual performance by self-reported questionnaire revealed satisfactory results in terms of subjective visual quality improvement. CONCLUSION: Objective optical quality parameters show good visual outcomes. Subjective visual quality assessed by self reported questionnaire in the presbyopia correction group show satisfactory results. PMID- 29600182 TI - Three-year results of small incision lenticule extraction and wavefront-guided femtosecond laser-assisted laser in situ keratomileusis for correction of high myopia and myopic astigmatism. AB - AIM: To compare and calculate the 3-year refractive results, higher-order aberrations (HOAs), contrast sensitivity (CS) and dry eye parameters after small incision lenticule extraction (SMILE) and wavefront-guided femtosecond laser assisted laser in situ keratomileusis (FS-LASIK) for correction of high myopia and myopic astigmatism. METHODS: In this prospective, non-randomized comparative study, 78 eyes with spherical equivalent (SE) of -8.11+/-1.09 diopters (D) received a SMILE surgery, and 65 eyes with SE of -8.05+/-1.12 D received a wavefront-guided FS-LASIK surgery with the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany) for flap cutting. Visual acuity, manifest refraction, CS, HOAs, ocular surface disease index (OSDI) and tear break-up time (TBUT) were evaluated during a 3-year follow-up. RESULTS: The difference of uncorrected distance visual acuity (UDVA) postoperatively was achieved at 1mo and at 3mo, whereas the difference of the mean UDVA between two groups at 3y were not statistically significant (t=-1.59, P=0.13). The postoperative change of SE was 0.89 D in the FS-LASIK group (t=5.76, P=0.00), and 0.14 D in the SMILE group (t=0.54, P=0.59) from 1mo to 3y after surgery. At 3-year postoperatively, both HOAs and spherical aberrations in the SMILE group were obviously less than those in the FS-LASIK group (P=0.00), but the coma root mean square (RMS) was higher in the SMILE group (0.59+/-0.26) than in the FS-LASIK group (0.29+/-0.14, P=0.00). The mesopic CS values between two groups were not statistically significant at 3y postoperatively. Compared with the FS-LASIK group, lower OSDI scores and longer TBUT values were found in the SMILE group at 1mo and 3mo postoperatively. With regard to safety, no eye lost any line of CDVA in both groups at 3y after surgery. CONCLUSION: Both SMILE and wavefront-guided FS-LASIK procedures provide good visual outcomes. Both procedures are effective and safe, but SMILE surgery achieve more stable long-term refractive outcome and better control of early postoperative dry eye as compared to FS-LASIK. PMID- 29600183 TI - The relationship between abduction deficit and reoperation among patients with infantile esotropia. AB - AIM: To determine the relationship between abduction deficit and reoperation among patients with infantile esotropia (IET). METHODS: The records of 216 patients (432 eyes) with IET who underwent surgery, from 2010 to 2015 were studied. Patients with IET whose deviation appeared before 6mo of age and had stable preoperative deviation in two examinations with at least 2wk apart and a minimum 3mo postoperative follow up were included. Cases with early onset accommodative esotropia, congenital cataract, retinopathy of prematurity (ROP), manifest nystagmus, fundus lesions, neurologic and ophthalmic anomalies, 6th nerve palsy and Duane's syndrome were excluded. Preoperative abduction deficit was considered from -1 to -3 grading scale. Three months after surgery, children were classified into no-need reoperation [deviation<=15 prism diopters (PD)], and need-reoperation groups (deviation>15 PD). RESULTS: In this retrospective study, 117 female and 99 male patients with the mean surgical age of 4.7+/-6.4y were included. Reoperation rate was 33.3% and 16.0% in IET patients with and without abduction deficit, respectively in patients who had a history of late surgery. Abduction deficit increased the odds of reoperation by 82% [OR=1.82, 95% confidence interval (CI) =1.05 to 3.19, P=0.003] in patients who had a history of late surgery (>2 years old, P=0.021). Abduction deficit was improved significantly after operation (P<0.001). CONCLUSION: Based on our results, abduction deficit can be considered as a risk factor of reoperation in IET patients who are operated at the age of more than 2y.

AB - AIM: To compare a trifocal intraocular lens (IOL) and a bifocal IOL implantation in improving visual function after cataract surgery. METHODS: Eligible literatures were systematically searched through EMBASE and PubMed databases. The inclusion criteria were prospective comparative clinical trials on cataract surgery comparing trifocal IOL with bifocal IOL implantation that assessed visual acuity, contrast sensitivity and subjective vision quality. The effects were computed as standardized mean differences and pooled using fixed-effect or random effect models. RESULTS: Four prospective randomized controlled trials (RCTs) and five cohorts provided data were included by a systematic review, comprising 265 eyes implanted with trifocal IOLs and 264 eyes implanted with bifocal IOLs. Monocular distance visual acuity (VA) showed a statistically significant but small difference that favored trifocal IOLs (MD=-0.06; 95%CI, -0.10 to -0.02; Z=2.90, P=0.004 for uncorrected distance VA, and MD= -0.02; 95%CI, -0.03 to 0.00; Z=2.02, P=0.04 for corrected distance VA), but the data did not suggest that the effect of trifocal IOL implantation would clinically outperform bifocal IOL implantation. There was no significant difference in monocular near VA (MD= 0.01; 95%CI, -0.07 to 0.04; Z=0.42, P=0.68 for distance-corrected near VA, and MD=-0.01; 95%CI, -0.06 to 0.03; Z=0.55, P=0.58 for corrected near VA) or refraction between two groups. Contrast sensitivity and subjective visual quality had no conclusive results. CONCLUSION: All results indicate that trifocal IOL and bifocal IOL had similar levels of monocular distance and near VA. PMID- 29600185 TI - The relationship between insulin resistance/beta-cell dysfunction and diabetic retinopathy in Chinese patients with type 2 diabetes mellitus: the Desheng Diabetic Eye Study. AB - AIM: To investigate the relationship between insulin resistance (IR)/beta-cell dysfunction and diabetic retinopathy (DR) in Chinese patients with type 2 diabetes mellitus (T2DM), and to explore further whether there were differences in the relationship among diabetic patients with higher and lower body mass index (BMI). METHODS: Cross-sectional study. A total of 1466 subjects with T2DM were recruited in a local Desheng Community of urban Beijing from November 2009 to June 2012 for the cohort of Beijing Desheng Diabetic Eye Study. Standardized evaluation was carried out for each participant, including questionnaire, ocular and anthropometric examinations, and laboratory tests. Seven fields 30 degrees color fundus photographs were used for DR grading according to the Early Treatment Diabetic Retinopathy Study protocols. Homeostatis Model Assessment (HOMA) method was employed for IR and beta-cell function assessment. RESULTS: After excluding those participants who were treated with insulin (n=352) or had missing data of fasting insulin (n=96), and further excluding those with poor quality of retinal photographs (n=10), a total of 1008 subjects were included for the final analysis, 406 (40.3%) were men and 602 (59.7%) were women, age ranging from 34 to 86 (64.87+/-8.28)y. Any DR (levels 14 and above) was present in 278 (27.6%) subjects. After adjusting for possible covariates, the presence of any DR did not correlate with HOMA IR [odds ratio (OR) 1.51, 95% confidence interval (CI) 0.87-2.61, P=0.14] or HOMA beta-cell (OR 0.71, 95%CI 0.40-1.26, P=0.25). After stratification by BMI, the presence of any DR was associated positively with HOMA IR (OR 2.46, 95%CI: 1.18-5.12, P=0.016), and negatively with HOMA beta cell (OR 0.40, 95%CI: 0.19-0.87, P=0.021) in the group of patients with higher BMI (>=25 kg/m2). In the group of patients with lower BMI (<25 kg/m2), the presence of any DR was not associated with HOMA IR (OR 1.00, 95%CI: 0.43-2.33, P=1.00) or HOMA beta-cell (OR 1.41, 95%CI: 0.60-3.32, P=0.43). CONCLUSION: The data suggest that higher IR and lower beta-cell function are associated with the presence of DR in the subgroup of diabetic patients with higher BMI. However, this association is not statistically significant in diabetic patients with lower BMI. PMID- 29600186 TI - Symptomatic accommodative and binocular dysfunctions from the use of flat-panel displays. AB - AIM: To determine the presence of symptomatic accommodative and non-strabismic binocular dysfunctions (ANSBD) in a non-presbyopic population of video display unit (VDU) users with flat-panel displays. METHODS: One hundred and one VDU users, aged between 20 to 34y, initially participated in the study. This study excluded contact-lens wearers and subjects who had undergone refractive surgery or had any systemic or ocular disease. First, subjects were asked about the type and nature of eye symptoms they experienced during VDU use. Then, a thorough eye examination excluded those subjects with a significant uncorrected refractive error or other problem, such as ocular motility disorders, vertical deviation, strabismus and eye diseases. Finally, the remaining participants underwent an exhaustive assessment of their accommodative and binocular vision status. RESULTS: Eighty-nine VDU users (46 females and 43 males) were included in this study. They used flat-panel displays for an average of 5+/-1.9h a day. Twenty subjects presented ANSBD (22.5%). Convergence excess was the most frequent non strabismic binocular dysfunction (9 subjects), followed by fusional vergence dysfunction (3 subjects) and convergence insufficiency (2 subjects). Within the accommodative dysfunctions, accommodative excess was the most common (4 subjects), followed by accommodative insufficiency (2 subjects). Moderate to severe eye symptoms were found in 13 subjects with ANSBD. CONCLUSION: Significant eye symptoms in VDU users with accommodative and/or non-strabismic binocular dysfunctions often occur and should not be underestimated; therefore, an appropriate evaluation of accommodative and binocular vision status is more important for this population. PMID- 29600187 TI - Endoscopy-assisted vitrectomy in the anterior vitreous. AB - Endoscopy-assisted ocular surgery is a relatively old technique that is increasingly being recognized for its application in cases of vitreoretinal disease. This technique is especially useful when both the vitreous and retina are difficult to access because of media opacity, a small pupil, or a microcornea. In this context, the anterior vitreous is often difficult to dissect because of its complex pathological changes. This article reviews the common anatomical features and pathologies that are observed in the anterior vitreous, as well as the applications and indications of endoscopy-assisted vitrectomy in the anterior vitreous. PMID- 29600188 TI - Lamellar keratoplasty with corneoscleral graft for limbal dermoids. AB - To assess the postoperative outcomes of limbal dermoid excision with corneoscleral graft transplantation. The charts of 8 consecutive patients (mean age: 13.0y) who had undergone limbal dermoid excision with lamellar corneoscleral graft transplantation by a single surgeon were retrospectively reviewed. Mean dermoid size was 7.75 mm (6.0-12.0 mm). Mean visual acuities (in logMAR units) before and after surgery were 1.8 and 1.7, respectively (P=0.29). Spherical equivalents were 1.3 diopter (D) before surgery and 0.7 D after surgery (P=0.40). The mean astigmatism measurements before and after surgery were 2.4 D and 1.5 D, respectively (P=0.17). Vector analysis revealed a mild change in astigmatism with a mean "d" of 3.2 (0.56-6.89). No intra- or post-operative complications occurred. Lamellar keratoplasty for limbal dermoids is safe and offers good cosmesis and tectonic stability. A significant decrease in the amount of astigmatism is not expected following surgery. PMID- 29600189 TI - A comparison of surgical efficacy between a 1.8-mm microincision and 3.2-mm and 5.5-mm incisions for phacoemulsification. AB - Phacoemulsification is a commonly used surgical method in cataract surgery. This paper observes and compares the surgical efficacy of three incisions of different length for phacoemulsification to identify the optimal method for cataract surgery. Ninety patients were enrolled in the present study and divided into three groups. The 1.8-mm group received Bausch & Lomb MI60 foldable intraocular lens (IOL) implantation (n=30), 3.2-mm group received Bausch & Lomb Akreos AO foldable lens implantation (n=30), and 5.5-mm group received Alcon TYPE 05 rigid IOL implantation (n=30). Visual acuity, Oculyzer-based anterior segment analysis, and corneal endothelial cell count before surgery, and 3, 7, 30, and 90d after surgery were recorded and compared. Pseudophakic accommodation three days, one week, one month, and three months after surgery was determined. Intraoperative ultrasound time and ultrasonic energy were recorded. It was finally concluded that for phacoemulsification with the same phaco tip, a 1.8-mm microincision can lead to quicker recovery of visual acuity, more stable astigmatism, and higher pseudophakic accommodation than conventional incision. PMID- 29600190 TI - Toxocara optic neuropathy: clinical features and ocular findings. AB - We evaluated thirteen eyes of twelve patients diagnosed clinically and serologically with Toxocara optic neuropathy. Eleven patients had unilateral involvement and one patient had bilateral optic neuropathy. Eight patients (66.7%) had a possible infection source to Toxocara. Six patients (50%) had painless acute optic neuropathy. Ten eyes had asymmetric, sectorial optic disc edema with peripapillary infiltration and three eyes had diffuse optic disc edema. Eosinophilia was noted in five patients (41.7%) and optic nerve enhancement was observed in eight of eleven eyes (72.7%) with available orbit magnetic resonance imaging (MRI). Mean visual acuity significantly improved following treatment [mean logarithmic of the minimum angle of resolution (logMAR) 0.94+/-0.56 at baseline and 0.47+/-0.59 at the final (P=0.02)]. Asymmetric optic disc edema with a peripapillary lesion and a history of raw meat ingestion were important clues for diagnosing Toxocara optic neuropathy. Additionally, Toxocara IgG enzyme-linked immunosorbent assay (ELISA) test and evaluating eosinophil may be helpful for diagnosis.

AB - Combined loss of tumor suppressors (TSPs), PTEN, TP53, and RB1, is highly associated with small cell carcinoma of prostate phenotype. Recent genomic studies of human tumors as well as analyses in mouse genetic models have revealed a unique role for these TSPs in dictating epithelial lineage plasticity-a phenomenon that plays a critical role in the development of aggressive variant prostate cancer (PCa) and associated androgen therapy resistance. Here, we summarize recently published key observations on this topic and hypothesize a possible mechanism by which concurrent loss of TSPs could potentially regulate the PCa disease phenotype. PMID- 29600195 TI - Lvr, a Signaling System That Controls Global Gene Regulation and Virulence in Pathogenic Leptospira. AB - Leptospirosis is an emerging zoonotic disease with more than 1 million cases annually. Currently there is lack of evidence for signaling pathways involved during the infection process of Leptospira. In our comprehensive genomic analysis of 20 Leptospira spp. we identified seven pathogen-specific Two-Component System (TCS) proteins. Disruption of two these TCS genes in pathogenic Leptospira strain resulted in loss-of-virulence in a hamster model of leptospirosis. Corresponding genes lvrA and lvrB (leptospira virulence regulator) are juxtaposed in an operon and are predicted to encode a hybrid histidine kinase and a hybrid response regulator, respectively. Transcriptome analysis of lvr mutant strains with disruption of one (lvrB) or both genes (lvrA/B) revealed global transcriptional regulation of 850 differentially expressed genes. Phosphotransfer assays demonstrated that LvrA phosphorylates LvrB and predicted further signaling downstream to one or more DNA-binding response regulators, suggesting that it is a branched pathway. Phylogenetic analyses indicated that lvrA and lvrB evolved independently within different ecological lineages in Leptospira via gene duplication. This study uncovers a novel-signaling pathway that regulates virulence in pathogenic Leptospira (Lvr), providing a framework to understand the molecular bases of regulation in this life-threatening bacterium. PMID- 29600196 TI - Vibrio vulnificus RtxA1 Toxin Expression Upon Contact With Host Cells Is RpoS Dependent. AB - The expression of virulence genes in bacteria is known to be regulated by various environmental and host factors. Vibrio vulnificus, an estuarine bacterium, experiences a dramatic environmental change during its infection process. We reported that V. vulnificus RtxA1 toxin caused acute cell death only when close contact to host cells was allowed. A sigma factor RpoS is a very important regulator for the maximal survival of pathogens under stress conditions. Here, we studied the role of RpoS in V. vulnificus cytotoxicity and mouse lethality. The growth of rpoS mutant strain was comparable to that of wild-type in heart infusion (HI) media and DMEM with HeLa cell lysate. An rpoS mutation resulted in decreased cytotoxicity, which was restored by in trans complementation. Interestingly, host contact increased the expression and secretion of V. vulnificus RtxA1 toxin, which was decreased and delayed by the rpoS mutation. Transcription of the cytotoxic gene rtxA1 and its transporter rtxB1 was significantly increased after host factor contact, whereas the activity was decreased by the rpoS mutation. In contrast, the rpoS mutation showed no effect on the transcriptional activity of a cytolytic heamolysin gene (vvhA). Additionally, the LD50 of the rpoS mutant was 15-fold higher than that of the wild-type in specific pathogen-free CD-1 female mice. Taken together, these results show that RpoS regulates the expression of V. vulnificus RtxA1 toxin and its transporter upon host contact.

PMID- 29600199 TI - Radial Artery Pseudoaneurysm in a Post-operative Case of Midshaft Radius Fracture. AB - Introduction: Pseudoaneurysms of arteries are not uncommon complications of vessel handling during surgery. Early identification and management is important to prevent disastrous complications such as rupture and thrombosis. Case Report: We describe a case of a 28-year-old male who developed a pseudoaneurysm of the radial artery after being operated by plating for a mid-shaft radius fracture. He presented 2 weeks after surgery with swelling over the forearm which was confirmed to be a pseudoaneurysm after computed tomography angiography. It was treated with surgical excision and end-to-end anastomosis. Conclusion: A high index of suspicion must be maintained about the occurrence of this complication secondary to both trauma and surgery. PMID- 29600197 TI - Herpes Simplex Virus Type 1 Infects Enteric Neurons and Triggers Gut Dysfunction via Macrophage Recruitment. AB - Herpes Simplex Virus type 1 (HSV-1), a neurotropic pathogen widespread in human population, infects the enteric nervous system (ENS) in humans and rodents and causes intestinal neuromuscular dysfunction in rats. Although infiltration of inflammatory cells in the myenteric plexus and neurodegeneration of enteric nerves are common features of patients suffering from functional intestinal disorders, the proof of a pathogenic link with HSV-1 is still unsettled mainly because the underlying mechanisms are largely unknown. In this study we demonstrated that following intragastrical administration HSV-1 infects neurons within the myenteric plexus resulting in functional and structural alterations of the ENS. By infecting mice with HSV-1 replication-defective strain we revealed that gastrointestinal neuromuscular anomalies were however independent of viral replication. Indeed, enteric neurons exposed to UV-inactivated HSV-1 produced monocyte chemoattractant protein-1 (MCP-1/CCL2) to recruit activated macrophages in the longitudinal muscle myenteric plexus. Infiltrating macrophages produced reactive oxygen and nitrogen species and directly harmed enteric neurons resulting in gastrointestinal dysmotility. In HSV-1 infected mice intestinal neuromuscular dysfunctions were ameliorated by in vivo administration of (i) liposomes containing dichloromethylene bisphosphonic acid (clodronate) to deplete tissue macrophages, (ii) CCR2 chemokine receptor antagonist RS504393 to block the CCL2/CCR2 pathway, (iii) Nomega-Nitro-L-arginine methyl ester hydrochloride (L NAME) and AR-C 102222 to quench production of nitrogen reactive species produced via iNOS. Overall these data demonstrate that HSV-1 infection makes enteric neurons recruit macrophages via production of a specific chemoattractant factor. The resulting inflammatory reaction is mandatory for intestinal dysmotility. These findings provide insights into the neuro-immune communication that occurs in the ENS following HSV-1 infection and allow recognition of an original pathophysiologic mechanism underlying gastrointestinal diseases as well as identification of novel therapeutic targets. PMID- 29600200 TI - Primary Lymphoma of the Pelvis: A Case Report. AB - Introduction: Primary lymphoma of the bone (PLB) is uncommon clinical entity with the vast majority of the cases are non-Hodgkin's lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of PLB. Case Report: We report a case of 60-year-old female presented with pain in the right hip that persisted for 2 months. Plain X-ray, computed tomography, and magnetic resonance imaging of the right hip showed a lytic lesion involving the right acetabulum and adjoining iliac bone with extraosseous mass. The histopathological and immunohistochemical examination confirmed a diagnosis of DLBCL. Treatment with cyclophosphamide, epirubicin, vincristine, and prednisone plus rituximabestablished a complete response (CR) with remodeling of the acetabulum. At the last follow-up, the patient had the ability to walk without any support which obviates the need of primary surgical interference for the tumor. Conclusion: The PLB must be considered in the differential diagnosis of lytic lesions involving the pelvic bones in older adults, especially when accompanied by extraosseous soft tissue mass. Our patient of PLB showed goodremodeling of the acetabular area after CR to chemotherapy without primary surgical interference for the tumor with the limitation of weight-bearing during chemotherapy treatment to prevent fracture. PMID- 29600201 TI - Femoral Head Stress Fracture in Children: A Case Report. AB - Introduction: The stress fracture of the femoral head rarely occurs; but, it is generally encountered in case of bone insufficiency, and it is exceptional in younger individuals. The main differential diagnosis may include several diseases, namely, slipped upper femoral epiphysis, septic arthritis, osteomyelitis, and Perthes' disease. Bone scintigraphy is very sensitive but lacks specificity. Nowadays, the magnetic resonance imaging (MRI) is the gold standard for an accurate diagnosis. Case Report: We present the first description of this pathology in the pediatric population with the particularity of its atypical aspect on MRI through a case of stress fracture of femoral head in 12 year-old female. Conclusion: Stress fractures may sometimes mimic malignant or infectious lesions and are easily misdiagnosed. MRI is the gold standard which may be the only modality to identify the fracture. PMID- 29600202 TI - Late and Vague Presentation of Septic Arthritis of Hip in a IVDrug Abuser. AB - Introduction: Septic arthritis of the hip is a rare entity in acute presentation of hip pain in adults. Even though hip is the second most commonly affected joint, adult patients with septic arthritis not related to a surgical procedure represent <0.00001% of total acute admissions. Case Report: We present a 32-year old female intravenous drug abuser, positive for Hepatitis B and C who had started to inject her femoral veins 2 years ago. She presented with a 10 weeks history of radiating pain in the leg which was full, constant and diffuse in nature with hip stiffness. She was treated for sciatica by her GP. She had later visited A and E twice (5 and 8 weeks) and was again treated symptomatically. She started to have increasing pain, hip stiffness, reduced mobility, and developed swelling of both legs extending upto groin medially. The patient was apyrexial throughout these visits. She did not have back/buttock pain. X-ray showed loss of joint space with evidence of articular surface destruction. Ultrasound showed no fluid collection inside the joint and deep vein thrombosis was ruled out. Hip joint was aspirated, and cultures grew Staphylococcus aureus from the aspirate. Flucloxacillin and fucidin were started as per hospital protocol. Skin traction was applied for pain relief with active hip movements as possible. Magnetic resonance imaging demonstrated complete joint destruction post- infective septic arthritis. After 8 weeks of antibiotics, inflammatory markers improved. Follow up X-ray showed complete ankylosis of hip joint, severe restriction ofhip movements and was allowed weight bearing as possible. Conclusion: Risk of septic arthritis should always be considered in mind when dealing with these cohorts of patients. Threshold for septic arthritis should be much lower especially in patients with complicated history, current or ex-drug abuser and presenting with vague symptoms. Early diagnosis, detection of organisms, specific targeted antibiotics, and joint wash out with a future consideration of total hip arthroplasty when the infection has settled will help patients resume their normal function. PMID- 29600203 TI - Isolated Spontaneous Atraumatic Avulsion of Lesser Trochanter of Femur-A Pathognomonic Sign of Malignancy in Adults? A Case Report and Review of Literature. AB - Introduction: Avulsion fractures of lesser trochanter (LT) of femur are generally seen following trauma with intertrochanteric or sub trochanteric fractures. Non traumatic fractures of LT could oc-cur due to sudden violent contraction of the iliopsoas muscle that inserts on the LT; during vigorous exercise, or sudden pull involving flexion of hip. These are seen commonly in adolescents where the physis has not fused yet. Such a scenario in an adult patient most often or not leads to a diagnosis of an underlying malignancy or metastatic lesion. Case Report: A 60 year-old female patient, presented to the outpatient department of our institute with pain on walking, with no history of trauma. X-ray showed an incidental finding of avulsion of LT of femur. Magnetic resonance imaging showed a large intramedullary tumour in the metaphysis though she had no symptoms or signs of malignancy. On further evaluation, she was diagnosed with primary lung carcinoma with widespread metastasis. Biopsy from the proximal femur also revealed a metastatic lesion. She was given palliative treatment in the form of a proximal femoral nail after which she was started on chemoradiation. Conclusion: A high index of suspicion of malignancy should be maintained in atraumatic fracture of LT in adults until proved otherwise. Lesser trochanter fracture. PMID- 29600204 TI - Acetabular Fracture after Hip Hemiarthroplasty: One Stage Procedure to a Total Hip Arthroplasty after Stabilization of the Fracture by Means of Cerclage Wires. AB - Introduction: Hip fractures in the elderly pose an increasing problem in society. In the elderly, a bipolar hemiarthroplasty (HA) remains the treatment of choice in case of hip fractures related to osteoporosis. However, due to an ongoing osteoporosis in this age group, a periprosthetic femoral fracture and a fracture of the unresurfaced acetabulum are increasingly noticed.In the literature, no information can be found regarding the treatment options for this kind of periprosthetic acetabular fracture. Case Report: We present a case report of a patient suffering an acetabular fracture 6 years after a HA. A one stage surgical procedure was the treatment of choice, consisting of a stabilization the acetabulum fracture by means of cerclage wires and a conversion of the HA to a total hip arthroplasty (THA). 4 months after surgery, she regained her pre operative functional status, and a radiographic evaluation of the right hemipelvis showed good signs ofthe fracture healing without migration ofthe acetabular component. Conclusion: This case shows a "one stage" surgery solution for an acetabular fracture after HA. Stabilization of the acetabulum fracture by means of cerclage wires and a conversion ofthe HA to a THAis a viable solution for this rare and challenging problem. PMID- 29600205 TI - Open Reduction and Internal Fixation of Posterior Fracture Dislocation of the Shoulder Made Easy! AB - Introduction: Posteriorly dislocated humeral head fracture has a great implication, as it is associated with high risk of avascular necrosis, limited access through the deltopectoral approach, and posterior approach to the posteriorly dislocated humeral fracture increases the risk to the remaining blood supply. Technical Tip: Posteriorly dislocated humeral fracture is approached through deltopectoral approach. Schanz pin is inserted into the humeral head to achieve purchase in the humeral head. Applying laterally directed force the humeral head is disengaged from the lateral margin of glenoid. A rotatory force then repositions the humeral head into a congruous position. Open reduction internal fixation is then carried out in a standard fashion. Conclusion: Retrieving the humeral head from the posteriorly dislocated position in patients with posterior fracture dislocation of the shoulder can be challenge to a trauma surgeon. With this novel technique, humeral head is reduced through deltopectoral approach without increasing the risk to the remaining blood supply. PMID- 29600206 TI - A Unique Case of Cervical Myelopathy in an Adult Patient with Scheie Syndrome. AB - Introduction: Scheie syndrome is an extremely rare systematic disease that represents the most attenuated form of mucopolysaccharidosis Type I disorder. Although associated with a variety of manifestations, Scheie syndrome leading to the development of cervical myelopathyis yet to be reported. Our purpose was to present a unique case of a Scheie syndrome patient, who underwent surgery due to cervical myelopathy, and to discuss the clinical and imaging findings, as well as the challenges and outcomes of surgical treatment. Case Report: A 33-year-old man with Scheie syndrome presented with neck and radicular pain, upper extremity weakness, and insecure gait. The workup studies revealedcervical spine stenosis at multiple levels, caused by accumulation of soft tissue, within the cervical spinal canal. D espite the high risks of anesthesia, and the patient's inherent poor bone quality that could lead to failure of spinal fusion, we decided to proceed with surgery; indeed, decompressive laminectomies combined with C1-7 posterior stabilization led to immediate pain relief. Despite counter advised, the patient returned to sports rather early, and 6months after index procedure neck pain relapsed, while screw breakage and cutout occurred at the level of C7. Consequently, the initial instrumentation was revised and extended at T2 level. At 2years follow-up, the patient remained continuously pain-free and ambulatory. Conclusion: Although cervical myelopathy in Scheie syndrome represents an extremely rare entity, it can make a severe impact on patients' quality of life. If timely managed though, these patients can be offered a significant relief from symptoms. Surgery is rather challenging and treating physicians should be aware of the high risks of anesthesia. Especially spine surgeons should be aware of the nature of the disease, since it may not allow for fusion, causing instrumentation to fail. PMID- 29600207 TI - Treating a Recalcitrant Non-union of the Radius Using Autogenous Bone, Equine Bone Paste, Equine Demineralized Bone Matrix, Platelet Rich Plasma, and Bone Marrow Aspirate. A Case Report. AB - Introduction: Non-unions at forearms are usually challenging and difficult to treat. If additionally, an infection is present, reconstructive surgery should be planned only after full debridement, antibiotic treatment, and confirmation, based on clinical observation and laboratory tests that the infection has subsided. Bone grafting may be required for reconstruction. The use of autogenous bone calls for a second surgical site with an increased risk of morbidity. Using bone substitutes may reduce the need for autogenous bone. Stimulating factors, such as bone marrow concentrate (BMC) and demineralized bone matrix (DBM), may be used concomitantly with bone substitutes to facilitate bone regeneration. Case Report: The present report describes the case of a 38-year-old patient whose radius was fractured in a car accident. A first surgery involved stabilizing the reduced fracture with a plate, but an infection developed, and the bone did not heal. 3 months later, a second surgery followed, involving placing an antibiotic filled spacer. This did not cure the infection, so the spacer was replaced 3 months later, and a second antibiotic was added. The patient also began taking oral antibiotics. 6 months later, the patient underwent vascularized fibular grafting. However, the graft did not integrate, and a non-union developed. A year later, the non-union was treated by grafting autogenous bone from the iliac crest, equine bone substitute, and equine DBM, in conjunction with autologous BMC and platelet-rich plasma. At the 6-month follow-up, the bone structure appeared to be successfully reconstructed. Conclusion: A graft made of a combination of materials with both biological and physical properties can be used to foster bone regeneration for the treatment ofparticularly challenging cases ofnon-unions. PMID- 29600208 TI - Intra-articular Osteoid Osteoma of Femoral Neck Region: A Simplified Treatment Strategy and Review of Literature. AB - Introduction: Proximal femur is the common site for localization of benign bone lesions, and the diagnosis is often delayed and potentially challenging due to their atypical presentations. Early diagnosis is difficult as intra-articular lesions often present with clinical and radiological features of inflammatory synovitis in the joint. Case Report: Two patients of intra-articular osteoid osteoma in proximal femoral presented with atypical features limb lengthening, minimal reactive bone sclerosis, and multifocal nidus. They were managed with anterior open approach, en bloc resection of the lesion, placement of autologous cortical graft, and prophylactic fixation with dynamic hip screw. Conclusion: Intra-articular osteoid osteomas in proximal femoral neck present differently, making the diagnosis and treatment challenging. Anterior open approach, en bloc resection of the lesion, reinforcement, and prophylactic fixation with dynamic hip screw is a reasonable option for managing these lesions which can be easily done in an average clinical setup.

AB - Introduction: Anterior cruciate ligament (ACL) reconstruction is a "daily" surgery. Nevertheless, pretibial cyst formation is a very rare complication and may appear years after the reconstruction. Even more infrequent is the recurrence of this complication. Case Report: We present a patient who developed a pretibial cyst 44 months after an ACL reconstruction and who underwent three open surgeries due to recurrence. Up to date, there are no symptoms or signals of cyst recurrence after 18 months of follow-up. Conclusion: Initial surgical resection might have failed due to insufficient surgical treatment. In case of suspicion of articular communication, we consider that the correct treatment is the resection of the cyst, proper curettage of the tunnel walls and a thorough filling of the space with bone graft. This course oftreatment may avoid a recurrence. PMID- 29600210 TI - Endoscopic Calcaneoplasty for Haglunds Excision Using Two Lateral Portals. AB - Introduction: The main objective of this case report is to demonstrate endoscopic calcaneoplasty (ECP) using two lateral portals. Case Report: The patient is middle-aged male aged 40 years, with higher basal metabolic index (BMI) and was diagnosed having a Haglund's bump and was on conservative treatment for a period of over 6 months, with minimal relief. We did ECP with the patient in lateral decubitus position using two lateral portals instead of using one medial and one lateral portal, his American Orthopaedic Foot and Ankle Society score has improved from 64 to 98, and his Fowler-Philip angle is reduced from 71 degrees to 45 degrees . Conclusion: ECP using two lateral portals with patient in lateral position is comfortable for the patients with higher BMI and the surgical time can also be reduced. However, we need to perform more number of cases through this technique to conclude to the results. Endoscopic calcaneoplasty, two lateral portals, Haglund's bump.

Together with the fact that it can mimic a variety of disease entities, it imposes significant diagnostic challenge in our clinical practice. In this article, we report two patients diagnosed with spinal gout, and both were initially suspected to have a pyogenic infection. Case Reports: The first patient, a 66-year-old man, was admitted for fever and a short history of bilateral upper limb weakness. Clinical, biochemical, and radiological investigation results were suggestive of C5/6 infective spondylodiscitis with resultant cervical myelopathy. The second patient, a 68-year-old man, was admitted for fever and bilateral lower limb weakness and numbness compatible with cauda equina syndrome. Imaging showed L4/5 lytic spondylolisthesis with suspected abscesses formation around the pars defects. Both underwent emergency operations. Histological examinations of intraoperative specimens in both cases revealed tophaceous gout and microbiological studies were all negative. Urate-lowering agent was started for hyperuricemia. They both had partial neurological recovery. Conclusion: These two cases highlight how axial gout can mimic infective spondyloarthropathy clinically. In patients with multiple risk factors for gout presenting with back conditions, spinal gout should be considered as one ofthe differential diagnosis. With the availability of advanced imaging modality, dual energy computed tomography scan, pre-operative diagnosis of axial gout is now possible which may have implications on subsequent surgical approaches and medical treatment. Collaboration with the medical team to achieve good serum urate control is important to prevent disease recurrence. PMID- 29600212 TI - Upper Limb Phlegmasia Cerulea Dolens Secondary to Heparin-induced Thrombocytopenia: A Case Study. AB - Introduction: Phlegmasia cerulea dolens (PCD) is a rare pathology with a very high morbidity and mortality rate, which usually occurs in the lower limb. There is very little literature available to aid management. Case Report: We present a case of upper limb PCD in a 67-year-old female secondary to heparin-induced thrombocytopenia caused by warfarin bridging. She presented to the orthopedic team with upper limb compartment syndrome from a bleed around a peripherally inserted central catheter, for which she was urgently taken to the theater for fasciotomies. Postoperatively, the patient's platelets dropped and the upper limb pain and swelling continued; after conservative management and anticoagulation failed the patient had an upper limb amputation of her right arm. Conclusion: With limited guidelines and management options restricted by the large fasciotomy wounds, we believe amputation was the patients' best option.

AB - Introduction: The relationship between the morphometry of atlantoaxial joint and chronic atlantoaxial rotatory fixation (AARF) is well known, but disorders in the atlanto-occipital joint in chronic AARF are not fully elucidated. The authors report two rare cases of secondary deformities in the atlanto-occipital joint in chronic AARF. Case Reports: Two patients with chronic AARF were treated with closed manipulation, skull traction and halo-vest immobilization. Clinical outcomes and radiographs were reviewed retrospectively, focusing on pathological changes in the atlanto-occipital joint using multiplanar reconstruction computed tomography and three-dimensional computed tomography images. Case 1 (12-year-old girl) had rotatory subluxation with a superior facet deformity of the atlas in the atlanto-occipital joint before the initiation of treatment. After a series of conservative treatments, both atlantoaxial and atlanto-occipital rotatory fixation could not be reduced, and both the superior facet deformity of the atlas and osteoarthritic changes in the atlanto-occipital developed. She was monitored without surgery because the disorder progressed to the spontaneous fusion of the occipital bone to the axis. Case 2 (13-year-old boy) had rotatory subluxation without facet deformity of the atlas in the atlanto-occipital joint before the initiation of treatment. However, both the superior facet deformity of the atlas and osteoarthritic changes in the atlanto-occipital developed over time, and both atlantoaxial and atlanto-occipital rotatory fixation could not be reduced after a series of conservative treatments. He still had severe neck pain and severely restricted neck mobility and underwent spinal fusion. Conclusion: Atlanto occipital rotatory subluxation and facet deformity in the atlanto-occipital joint may occur after prolonged AARF. It is necessary to pay attention to pathological changes not only in the atlantoaxial joint but also in the atlanto-occipital joint, when orthopedic surgeons treat patients with AARF. PMID- 29600214 TI - An Intramuscular Chondrolipoma of the Scapula: A Case Report of a Rare Tumor in an Unusual Location. AB - Introduction: Chondrolipomas are rare benign mesenchymal tumors primarily occurring in the shoulder region. To the best of our knowledge, only one case of chondrolipoma arising from the shoulder has been reported. We herein report an intramuscular chondrolipoma located in an unusual area of the scapula. Our case is interesting because magnetic resonance imaging (MRI) that shows lipomatous tumor masses with cartilaginous nodules may mislead surgeons into not considering the possibility of chondrolipomas. Case Report: A 62-year-old female, without any systemic disease, trauma, or history of surgery, presented with a unique case of a large intramuscular chondrolipoma ofthe scapula. This protruding lump over the right shoulder was present for 3 months in the patient without pain or limited range of motion. A sonographic evaluation revealed a homogeneous hypoechoic lesion in the posterior right shoulder. MRI showed that the chondrolipoma measured 7.5 x 4.6 x 3.9 cm, without remarkable bony invasion, with high signal intensity over the mass in T1- weighted images, indicating cystic changes, and mild signal enhancement within the cyst in T2-weighted images. Surgical marginal excision was performed. We identified yellowish, greasy, and firm soft tissue and two cartilaginous nodules inside the lipomatous tissue. Pathological findings revealed mature adipose tissue with a fibrous capsule and true cartilage inside. Post-operative outpatient follow-up found no recurrence after 2 years. Conclusion: Intramuscular chondrolipoma arising from the shoulder has been rarely reported. MRI and sonography are helpful in the diagnosis. PMID- 29600215 TI - Tuberculous Tenosynovitis of the Wrist and the Hand: The 3 Anatomo- Clinical Forms Described by Kanavel (About 4 Cases). AB - Introduction: Tuberculous tenosynovitis localization is rare. This unusual presentation, often misunderstood, results in frequent misdiagnosis. We report 4 cases of patients which represent the 3 anatomo-clinical forms described by Kanavel. The knowledge of its different manifestations will make it possible to recognize and to suspect the tuberculous origin. Case Report: This was a retrospective study from January 2006 to May 2017 which involved all patients received and treated with tuberculous tenosynovitis. Of the 4 case studies presented here, there were 3 men and 1 woman, aged, respectively, 23, 30, 40, and 30 years of age. They were all immunocompetent. The onset was, respectively, about 12, 6, 4, and 8 months. The localization was on the wrist for 3 cases (2 on the right and 1 on the left) and one on the palmar face of the second ray on the right hand. Signs of median nerve compression were found in 2 cases. Surgery was extensive, with a complete debridement in 3 patients. For the last one, a simple recess was made associated with a bacteriological sampling. Biopsy was performed for all patients. In the anatomo-clinical study, we observed 1 case of serofibrinous synovitis, 2 cases of rice-like synovitis, and 1 case of caseous synovitis. A rupture of the tendon ofthe flexor carpi radialis was observed in 1 case. All cases were confirmed histologically with the presence of granuloma gigantocellular with caseous necrosis. We have recorded 1 case ofbacteriological positivity in 3 cases requested. Patients had antituberculous chemotherapy after surgery for, respectively, 6, 8, 6, and 8 months. The progression was favorable with a regression of the signs of nerve compression. Revisited at, respectively, 4, 3, 5 years, and 34 months, we did not record any recurrence. The mobility of the wrist was complete and partial for the finger. Conclusion: Tenosynovitis tuberculous treatment is mostly medical. Early diagnosis enables the treatment to be started as soon as possible to avoid extensive surgery. For this reason, it is currently essential to use high sensitivity diagnostic methods of such as the polymerase chain reaction method and the Genexpert in any suspicion of the disease. PMID- 29600216 TI - A Rare Case of Intraneural Neurothekeoma of Median Nerve Mimicking Carpal Tunnel Syndrome. AB - Introduction: Neurothekeomas are uncommon benign soft tissue tumors of the peripheral nerves. It is commonly found in the upper extremities and in the head and the neck region as a small, asymptomatic, and superficial nodule. Case Report: We report a rare case of intraneural neurothekeoma (2.8 chi 2.4 x 1.8 cm) of the median nerve at the wrist in a 56-year-old female, which presented with clinical features of carpal tunnel syndrome. Conclusion: Carpal tunnel syndrome caused by intraneural neurothekeoma has been rarely reported. Clinicians should be aware of this rare cause of carpal tunnel syndrome. PMID- 29600217 TI - Double Posterior Cruciate Ligament Sign on Magnetic Resonance Imaging: Imaging Variants, Mimics, and Clinical Implications. AB - Introduction: Double posterior cruciate ligament (PCL) sign is a sign on magnetic resonance imaging (MRI) which is suggestive of a bucket- handle tear (BHT) of the meniscus. We undertook this study to assess the presence of a double PCL sign and its correlation with arthroscopic findings. We also discussed the various mimics and variants of the double PCL sign. Case Report: All the patients with a double PCL sign on the MRI and who underwent knee arthroscopy between January 2012 and December 2016 (total of 5 cases, 4 males and one female) were included in the study. A correlation between the imaging findings and the MRI findings was done. All these young patients were aged between 22 and 41 years. Two patients underwent arthroscopic partial meniscectomy, and three patients underwent arthroscopic meniscal repair using all inside technique. Conclusion: It is necessary for the sports physician to understand and recognize this important and subtle sign on MRI which is suggestive of a BHT of the meniscus. It is also important to identify the mimics of this sign and its variants for better management planning and patient prognostication. PMID- 29600218 TI - Arthroscopic Fixation of Tibial Spine Avulsion in Skeletally Immature: The Technique. AB - Introduction: Tibial spine avulsion fracture is more frequent in children than adults. Various methods of fixation have been mentioned, but concern remains about crossing the tibial physis. We present a technique of arthroscopic fixation with non-absorbable suture. Case Report: A total of 10 skeletally immature patients with tibial spine avulsion of Meyers and McKeever Type 2 and 3 were included in the study. The knee was arthroscopically cleared of hematoma. The avulsed tibial insertion of anterior cruciate ligament was reduced and held in place with tibial guide. By drilling guide wire through the tibia, reduced fragment, a fiber wire was passed. The avulsed fragment was tied on a suture post on tibia. Outcome was evaluated radiologically and clinically (Lysholm score, pivot shift, and KT 1000) at 12 months after surgery. All cases attained full range of motion, stable knee and could return to previous level of activity. The mean pre-operative Lysholm score of 50.8 +/- 1.4 (35-59) improved to 96.3 +/- 2.9 (92-100). The mean pre-operative anterior translation of tibia (measured by KT 1000) of 7.6 +/- 1.26 improved significantly to mean of 3.3 +/- 0.82 mm after surgery. Conclusion: The presented technique of arthroscopic fixation of avulsed tibial spine is a simple technique that provides reproducible results. It also offers cost-effective secure fixation.

AB - Introduction: Hematogenous osteomyelitis of long bones in immunocompetent adults is extremely rare and uncommonly presents as a pathological fracture. Case Report: A 53-year-old Caucasian male presented with an atraumatic mid-shaft femur fracture secondary to hematogenous osteomyelitis. The organism was found to be Streptococcus anginosus. The patient required multiple surgical debridements and was treated with an antibiotic-impregnated cement rod and external fixator along with IV Rocephin. Furthermore, the patient was on chronic Carbamazepine therapy for the refractory bipolar disorder. We discuss the effect cytochrome p450 inducing medications have on bone health and how this may have contributed to this rare presentation of pathologic fracture. Conclusion: We report a rare case of femoral osteomyelitis presenting as a pathologic fracture. Treatment involves multiple surgeries and an extended recovery.

AB - Introduction: Non-tuberculous mycobacteria (NTM) are slow-growing organisms affecting both immunocompromised and immunocompetent patients. As compared to tuberculosis, they pose formidable challenge in successful management beginning with diagnosis extending through its treatment. Case Report: Our case highlights unusual spinal presentation of NTM, intricacies in diagnosis, and successful management. Conclusion: As the prevalence of NTM is rising, it is important as clinicians to understand unique aspects which differ from tuberculosis for appropriate and successful treatment. PMID- 29600222 TI - A large cystic gastrointestinal stromal tumor within lesser sac: A diagnostic dilemma. PMID- 29600221 TI - Prognostic factors and outcomes in anaplastic gliomas: An institutional experience. AB - Background: There is lack of clear evidence and treatment guidelines for anaplastic gliomas (AGs) with very few studies focusing exclusively on these patients. The aim of the study was to analyze the clinical profile and survival in these patients. Materials and Methods: Patients of AGs treated with radiation and concurrent +/- adjuvant chemotherapy from January 2010 to December 2015 were analyzed. Statistical analysis was done using SPSS version 20 software. Results: A total of 100 patients were included in the study. The median age was 35 years (range 6-68 years). Eighty-four patients had follow-up details and were included for survival analysis. The 5-year overall survival (OS) was 58%. Age, presentation with seizures, and focal neurological deficit were not found to significantly influence survival. The 5-year survival for oligodendroglioma and astrocytoma was 69% and 52%, respectively. Patients with Karnofsky Performance Score (KPS) of >=70 had a significantly better 5-year OS (65%) as compared to those with KPS <70 (33%) (P = 0.000). The use of adjuvant temozolomide (TMZ) showed longer 5-year OS of 67.7% compared to 36% in patients who did not receive adjuvant chemotherapy (P = 0.018). Patients receiving both concurrent and adjuvant TMZ showed longer 5-year OS (68.5% vs. 40%, P = 0.010). Twenty-two patients had recurrence with average time to recurrence being 37 months. Fourteen patients underwent salvage surgery and two patients received reirradiation. Conclusions: OS significantly correlated with KPS and receipt of concurrent and adjuvant chemotherapy with TMZ. Therefore, adjuvant radiation with concurrent and adjuvant TMZ should be the standard of care for AGs. PMID- 29600223 TI - Estrogen receptor and progesterone receptor status of breast cancer patients of eastern India: A multi-institutional study. AB - Context: There is a paucity of any significant data on the estrogen receptor (ER) and progesterone receptor (PR) status of breast cancer patients from the eastern part of India. Aims: This study aims to document the ER and PR status of breast cancer patients in the eastern Indian population, as catered by two premier tertiary care hospitals in Kolkata. Subjects and Methods: All breast cancer patients registered between January 1, 2013 and December 31, 2015, in the Departments of Oncology, of IPGMER and SSKM Hospitals and R. G. Kar Medical College and Hospital, Kolkata, who had at least undergone a core biopsy or surgery, were analyzed retrospectively for documentation of their ER and PR status, using the 2010 American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) interpretation guidelines. Results: Over a period of 3 years, a total of 927 patients were included for the study. A total of 825 (89%) patients had their ER and PR data available for evaluation. ER and PR positive was seen in 312 (37.82%) patients, ER and PR negative in 399 (48.36%) patients, ER positive and PR negative in 71 (8.6%) patients, and ER negative and PR positive results was found in 43 (5.21%) patients. Conclusions: This is the first multi-institutional documentation of ER and PR status from eastern India, having a modest number of patients and one of the earliest documentations using the latest ASCO/CAP interpretation guidelines. These findings resemble the data from the south and also reiterate the fact that majority of the Indian breast cancer patients are still ER and PR negative in spite of the changes in the interpretation guidelines. PMID- 29600224 TI - Estrogen receptor, Progesterone receptor, and human epidermal growth factor receptor-2 status in breast cancer: A retrospective study of 5436 women from a regional cancer center in South India. AB - Aim: The aim of the study was to analyze the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) status over 7 years in South Indian women with breast cancer. Further analysis of a subgroup was done to study clinically defined subtypes and the role of preanalytical factors in needle core biopsies (NCBs) and excised specimens. Materials and Methods: This was a retrospective study from January 2010 to December 2016. Patients diagnosed with invasive breast cancer and available immunohistochemistry (IHC) reports of ER, PR, and HER2 status were analyzed. The cases for the year 2016 were analyzed further to observe the impact of preanalytical factors on the IHC staining patterns and surrogate status. Results: A total of 5436 patients were included with a median age of 48 years. Among these, 65% were <= 55 years. The overall incidence of hormone receptor (HR)-positive patients was 48%; HER2 positive, 15%; and triple-negative breast cancer (TNBC), 37%. The incidence of HR positive, HER2 positive, and TNBC were 45%, 16%, and 39% and 53%, 13%, and 34% in patients <56 years and over 55 years, respectively (P < 0.001). There was an increase in HR positivity and decrease in TNBCs over time. There was no significant difference in the staining patterns in NCBs and excised specimens. Conclusion: With time, there is an increase in hormone-positive tumors which may be attributed to better IHC techniques and tissue handling. There was no statistical difference in the patterns of ER, PR, and HER2 immunostaining in core biopsy and excised specimens. PMID- 29600225 TI - Comparison of health-related quality of life with epirubicin, cisplatin plus 5 fluorouracil and docetaxel, cisplatin plus 5-fluorouracil chemotherapy regimens as first-line systemic therapy in locally advanced inoperable or metastatic gastric or gastro-esophageal junction adenocarcinoma: A prospective study from South India. AB - Background: Health-related quality of life (HRQOL) is an important oncologic end point for upper gastrointestinal malignancies. Unfortunately, till date, there is no published prospective data from India, comparing the HRQOL parameters between first-line chemotherapy regimens in advanced/metastatic gastric cancer. Materials and Methods: The present study aimed to compare the HRQOL of first-line systemic chemotherapy with epirubicin, cisplatin plus 5-FU (ECF) and docetaxel, cisplatin plus 5-FU (DCF) regimens in patients with locally advanced inoperable or metastatic gastric or gastro-esophageal junction adenocarcinoma. The secondary end points were overall response rate, progression-free survival (PFS), overall survival (OS), and toxicity profile. Results: Between December 2014 and December 2016, 65 patients were treated with ECF (n = 34) or DCF (n = 31) regimen. The baseline HRQOL scores were comparable between the two study groups, with the exception of significantly poor pain and sleep difficulties symptom score in the DCF group. After three cycles of treatment, both the groups showed improvements in most of the quality of life (QOL) parameters including global QOL score, compared with their baseline status. After six cycles of chemotherapy, the ECF group showed nonsignificant deterioration for most of the QOL parameters; but on the contrary, the DCF group maintained improved scores for most of the QOL parameters. The median survival until a definitive deterioration of global QOL score was significantly better in the DCF arm in comparison to the ECF arm (7.1 vs. 5.6 months, respectively, P = 0.000). The median OS was 9.2 months with ECF and 12.5 months with DCF regimen (P = 0.000), while median PFS was 5.7 and 7.4 months with ECF and DCF regimens, respectively (P = 0.002). Conclusions: This prospective study highlighted a better impact of DCF chemotherapy on the HRQOL of patients with advanced/metastatic gastric cancer and showed the importance of QOL assessments in clinical trials to complement the risk-benefit judgment. PMID- 29600226 TI - Assessment of quality of life in resectable gastric cancer patients undergoing chemoradiotherapy as adjuvant treatment. AB - Introduction: Quality of life (QOL) is increasingly recognized as an important endpoint in cancer therapies. However, few data are available on QOL in patients who have received radiotherapy as adjuvant treatment for cancer stomach. Methods: Thirty patients who underwent curative resection were enrolled and received chemoradiotherapy (45 Gy in 25 fractions using three-dimensional conformal radiotherapy technique), together with 5-fluorouracil and leucovorin. The European Organization for Research and Treatment of Cancer QOL questionnaire C30 and STO Q22 was assessed at four time points: pre- and postchemoradiotherapy and at 1-month and 6-month follow-up. Results: Mean age of the patients was 54 years. Male:female ratio was 4:1. Stage II and Stage III disease was present in 60% and 30% of patients, respectively. All patients were able to complete the chemoradiotherapy protocol. Our study found out significant impairment in QOL for emotional functioning, fatigue, nausea and vomiting and dyspnea. Results showed that QOL levels decrease postchemoradiotherapy; however, QOL levels returned to baseline at 1-month and 6-month follow-up period. Conclusion: Chemoradiotherapy as adjuvant treatment for cancer stomach patients who have undergone resection with curative intent is a safe and well-tolerated regimen with respect to QOL. PMID- 29600227 TI - Pulmonary artery pseudoaneurysm secondary to metastatic breast cancer. PMID- 29600228 TI - Incidental gallbladder carcinoma: Utility of histopathological evaluation of routine cholecystectomy specimens. AB - Background: Incidental gallbladder carcinoma (IGBC) is rare cancer diagnosed during or after cholecystectomy done for benign gallbladder disease. The concern whether routine histopathological examination is needed for all cholecystectomy specimens still remains debatable. Materials and Methods: Twenty patients diagnosed with IGBC over a period of 2 years were retrospectively reviewed. Clinical details including clinical presentation, preoperative ultrasound (USG) findings, and macroscopic features were retrieved. Diagnosis of IGBC was confirmed on microscopic examination, and staging was done using the tumor node metastasis staging system. Results: Of the 4800 cholecystectomy specimens retrieved, diagnosis of IGBC was rendered in twenty cases (0.41%). Mean patient age was 50.65 years with a female preponderance. Preoperative USG detected an increase in wall thickness in six cases (30%) in contrast to gross examination which revealed the same in 55% (11/20) cases. Mucosal ulceration was observed in two cases (10%) of IGBC and seven cases (35%) did not reveal any preoperative or macroscopic findings suggestive of malignancy. Associated cholelithiasis was observed in 14 cases. Final diagnosis of IGBC was made on histomorphological assessment with tumor cells infiltrating the lamina propria in three cases (pT1b), muscularis propria in 15 cases (pT1b), and serosa in the remaining 2 cases (pT2). Conclusion: IGBC is a clinical masquerader which often evades the eye of a radiologist and comes as pathological surprise. Histopathological examination of cholecystectomy specimens remains the gold standard for the detection of this occult, yet notorious malignancy and assessment of the depth of invasion in IGBC guide further management. PMID- 29600229 TI - Epidemiology of liver cancer in Nile delta over a decade: A single-center study. AB - Background: In Egypt, there has been a remarkable increase in the proportion of hepatocellular carcinoma (HCC) among chronic liver diseases patients. This rising proportion may be explained by the increasing risk factors as hepatitis C virus (HCV) infection, hepatitis B virus (HBV) infection, improvement of the diagnostic tools of HCC as well as the extended survival among patients with cirrhosis to allow time for some of them to develop HCC. The aim of this study was to study the epidemiology of HCC in Nile delta over the last decade. Methods: The study was carried out on patients diagnosed as HCC in liver cancer clinic in Tanta University Hospital, Egypt, from January 2005 to January 2015. This retrospective study reviewed the files of HCC patients with special stress on age, sex, residence, occupation, smoking, and viral markers. Results: Over the last decade, 1440 HCC patients were diagnosed or referred to liver cancer clinic in Tropical Medicine Department in Tanta University Hospital from January 2005 to January 2015. The mean age of HCC patients was 56.13 +/- 9.53 years. Nearly, half of the patients with HCC were smokers and quarter of HCC patients were diabetics. HBV surface antigen-positive patients were only 3.26%, and the majority of patients were HCV-Ab positive (94.86% of patients). Conclusions: In Nile delta, hepatitis C rather than hepatitis B was linked to the development of HCC in our region which may be related to the high prevalence of HCV in this area. PMID- 29600230 TI - Standard-dose versus high-dose radiotherapy with concurrent chemotherapy in esophageal cancer: A prospective randomized study. AB - Objective: The objective of this study is comparision of local and distant control rates with high-dose versus standard-dose radiotherapy along with concurrent chemotherapy in esophageal cancer - a prospective randomized study. Materials and Methods: Histologically proven Stage I-III patients with carcinoma esophagus were randomized into two groups. One group has been treated with standard-dose radiotherapy, i.e., a total dose of 50.4 Gy (1.8 Gy/day, 28#, 5 days/week). The other group (study arm) has received high-dose radiotherapy, i.e. a total dose of 64.8 Gy (1.8 Gy/day, 36#, 5 days/week). Both groups have received 2 cycles of 3 weekly concurrent chemotherapy (cisplatin 75 mg/m[2] on day 1 and 5 fluorouracil 750 mg/m[2] continuous intravenous infusion over 24 h on day 1-4). Follow-up response evaluation was done by both endoscopy and computed tomography scan after 6-8 weeks and after 2 months thereafter. Results: Out of a total of 28 patients, 68% showed a complete response, 14% showed partial response, and 18% patients developed progressive disease at first and subsequent follow up (median follow-up of 21 months). Among the complete response patients, rates were higher in high-dose group compared to standard-dose radiotherapy group (71% vs. 64%, P = 0.38). Treatment-related toxicities were acceptable in both groups. Conclusion: High-dose radiotherapy with concurrent chemotherapy seems to be more effective with acceptable toxicity in our study. However, further follow-up and large sample size may be required to validate the current study conclusion. PMID- 29600231 TI - Outcomes of carcinosarcoma in a tertiary care institution in India. AB - Background: Carcinosarcoma is a rare malignancy, and reports are often mixed along with other sarcomas. The literature on uterine carcinosarcoma per se is sparse. Aims: This study aims to evaluate the demography, survival, and optimal treatment strategy of uterine carcinosarcoma. Settings and Design: A tertiary care center in India. The study design was descriptive with survival analysis. Materials and Methods: The medical records of all 18 patients admitted with uterine carcinosarcoma between January 2011 and December 2015 were reviewed. Baseline characteristics and outcomes were studied. Survival analysis was done using the Kaplan-Meier method and compared between treatment groups using the Log rank test. Results: The total number of uterine malignancies operated in our center over this time period was 311 of which 18 were carcinosarcomas (5.7%). Median age of presentation was 61 years (36-77 years). Most women (94%) were postmenopausal and 67% of them presented with postmenopausal bleeding. Over half of the patients (56%) presented late (Stage III or IV). Only 11 (61%) had adjuvant treatment and 7 patients had expired at the time of follow-up. The median survival was 284 days (95% confidence interval 107-461). Patients who received adjuvant therapy did better compared to those who did not (P = 0.036). Conclusions: Carcinosarcomas are aggressive tumors of postmenopausal women who present with bleeding or discharge per vaginum. In spite of adequate surgical staging followed by adjuvant therapy, survival remains poor. Improvements in early detection and optimal therapy need to be made. PMID- 29600232 TI - Geographical distribution of cervical cancer in Odisha: A 5-year retrospective study at a regional cancer center. AB - Background: Cancer cervix and breast are the two major female health problems in India. A hospital-based, 5-year (2010-2014) retrospective study was conducted at a regional cancer center of Odisha to analyze the present burden of cancer cervix in this state, which has a population of more than 45.5 million at present. Materials and Methods: All the patients suffering from cancer cervix that was treated by radiotherapy during 2010-2014 at this center were analyzed year wise for age, stage of disease, and native area. Results: Based on the Census 2011 data, it was calculated and found that from the low-literacy area on an average of 4.62 cervical cancer patients per million, from the medium-literacy area 6.56 patients per million, and from high-literacy area 19.11 patients per million of population have received radiotherapy in this hospital. More than 60% of patients with cervical cancer were from stage IIIB and in the age group of 50-55 years. Discussion: Odisha has 83.7% female population in rural areas with literacy rate below 50%. Due to lack of awareness and unavailability of cancer care facilities at their reach, they mainly depend on various alternative medicines in unscientific manner for their health care. Conclusion: Strengthening of existing regional cancer center, development of oncology wings in all medical college hospitals by providing basic radiotherapy facilities, emphasizing more on district cancer control programs, decentralizing of NGO schemes, and facilitating with more cancer screening and awareness programs may help better registration, prevention, and treatment of cancer in Odisha. PMID- 29600233 TI - Translation and validation of European Organization for Research and Treatment for Cancer quality of life questionnaire-OV-28 module into Indian languages (Hindi and Marathi) to study quality of life of ovarian cancer patients from a tertiary care cancer center. AB - Aim: The aim is to translate and validate the European Organization for Research and Treatment for Cancer (EORTC) ovarian cancer (OC) module (OV-28) into Hindi and Marathi to use for patients and scientific community. Methods and Results: The EORTC OV-28 was translated into Hindi and Marathi languages using prescribed guidelines by the EORTC. The process included forward translation by four translators (2 each for Hindi and Marathi). The questionnaires obtained were then given to independent backward-translators who then translated them back into English. These 2 questionnaires were then compared with the original EORTC questionnaire and the second intermediate questionnaires were formed. The second intermediate questionnaire was subsequently administered in twenty patients (10 each for Hindi and Marathi) diagnosed with OC who had never seen the questionnaire before, for pilot testing. Each of these ten patients after filling up the questionnaire themselves was then interviewed for any difficulty encountered during the filling up of the questionnaires. These were in the form of specific modules including difficulty in answering, confusion while answering, and difficulty to understand, whether the questions were upsetting and if patients would have asked the question in any different way. The suggestions were incorporated into the second intermediate questionnaires to form the final Hindi and Marathi ON-28 questionnaires. These questionnaires were then sent to the EORTC for the final approval to be used in clinical studies. Conclusion: We have successfully translated EORTC OV-28 module into Hindi and Marathi languages, and EORTC approved them to be used in clinical practice and studies for OC patients. PMID- 29600234 TI - Prophylactic salpingectomy and ovarian cancer: An evidence-based analysis. AB - Introduction: One of the ovarian carcinogenesis theories was the presence of premalignant cells in the epithelium of the fallopian tube. Therefore, the prophylactic salpingectomy during benign gynecological surgery is now expected as the attempt to reduce the ovarian cancer incidence. We studied the effect of prophylactic bilateral salpingectomy (PBS) in reducing the ovarian cancer incidence. Methods: This evidence-based report resulted from critical appraisal of 5 articles. It is aimed to answer our clinical question, can bilateral prophylactic salpingectomy reduce the incidence of ovarian cancer among women underwent hysterectomy for benign condition or permanent contraception surgery? The search was conducted on the Cochrane Library(r), PubMed(r), and Embase(r) using keywords of "prophylactic salpingectomy," and "ovarian cancer incidence." Reference lists of relevant articles were searched for other possibly relevant articles. Results: Five studies were included in our appraisal. The incidence of ovarian cancer among women underwent prophylactic salpingectomy is lower compared to women who were not underwent any intervention (2.2% to 13% and 4.75% to 24.4%). The salpingectomy may reduce 29.2% to 64% of ovarian cancer incidence. No significant effect of PBS to ovarian function, quality of life, sexuality, surgery duration, and its cost-effective profile were also found throughout our literature study. Conclusion: PBS is suggested to be performed for women during benign gynecological surgery as a primary preventive strategy of ovarian cancer. PBS is a cost-effective procedure, risk-reducing for ovarian cancer and has no significant effect to the ovarian function. PMID- 29600235 TI - Assessment of oral mucositis during concurrent chemoradiation of head and neck cancers using patient-reported measurement scale. AB - Introduction: Oral mucositis (OM) is a major challenge encountered in concurrent radiochemotherapy for the treatment of head and neck cancers. The patient reported OM symptoms scale (PROMS) was administered on these patients. The objective was to develop the similar scale in an Indian language and prescribe it population undergoing cancer treatment. Materials and Methods: PROMS scale was converted to Telugu language. Fifty-one patients took part in the study. All of them answered the 10-point questions marked their responses on 100 mm visual analog scale after thorough oral examination using WHO grading by the same examiner. Results: Internal consistency of Cronbach's alpha on PROMS scale was 0.81-0.97. The questionnaire study was administered on 35 males and 16 females with the mean age of 54.9 +/- 11.8. The decrease in the total PROMS score was marked on day 35 in almost all patients, with a mean value of 34.04 +/- 30.2 followed by a further significant decrease on day 60 (follow-up) with a mean of 3.71 +/- 7.8. The PROMS scores correlated strongly with the clinician-rated OM scores during the first 35 weeks from the baseline at 0.84 with P < 0.01 and poor correlation was at day 60, i.e. 0.32 with P < 0.05 using Spearman's Rho correlation. Conclusion: The study showed a good correlation between patient reported items and clinical score by standard grading scale. This questionnaire may not be a sole guide in assessing the severity of OM but could be definitely used as an adjunct to clinical oral examination at assessment levels. PMID- 29600236 TI - Squamous cell carcinoma of buccal mucosa: An analysis of prognostic factors. AB - Introduction: Carcinoma of the buccal mucosa is the most common oral cavity cancer in the Indian subcontinent. The aim of this study was to analyze the outcome and evaluate prognostic factors in surgically treated buccal mucosa squamous cell carcinoma (BMSCC) patients. Materials and Methods: A retrospective study was performed by reviewing the medical records of 409 pathologically proven buccal mucosa cancer patients, who were diagnosed and surgically treated in Tata Memorial Hospital between January 1, 2006, and December 31, 2008. Results: The overall 5-year survival of the cohort was found to be 54.1%. The stage-wise survival rate for tumor, node, metastasis (TNM) Stage I, II, III, and IV patients was found to be 85.2%, 82.9%, 56.3%, and 42.6% (P < 0.00), respectively. On multivariate Cox proportional hazard analysis, the presence of comorbidity, histological tumor size, pathological lymph node status, tumor differentiation, perineural invasion, and extracapsular spread were found to be independently associated with overall survival. Conclusion: BMSCC is an aggressive malignant tumor. In addition to TNM classification, other clinical and pathological factors also have a significant role in BMSCC prognostication. Hence, there is a need to move beyond TNM and develop a more inclusive, flexible, and easy to use prognostic system. PMID- 29600237 TI - Prospective study of sequential volumetric changes of parotid gland in early oropharyngeal carcinoma patients treated by intensity-modulated radiation therapy: An institutional experience. AB - Aims and Objectives: During course of radiation therapy, anatomical variations occur risking overdose of parotid gland. We tried to quantify volume of parotid gland and mean dose to parotid gland after every 10 fractions (#). Materials and Methods: We conducted the prospective study from July 2016 to May 2017 in 25 patients of early-stage oropharyngeal carcinoma. Patients had Karnofsy Performance Score of 80-100, median age was 54 years, and 18 patients were males. Patients were planned with intensity-modulated radiation therapy planning with dose as 66 Gy/30# to planning target volume (PTV) including primary and 54 Gy/30# to PTV-nodal including elective neck irradiation. After each 10#, replanning was done, and variations in parotid volume were studied including Dmean (mean dose to parotids) and D50 (the dose delivered to 50% of volume). Other tumor characteristic like PTV of primary was also assessed and minimum PTV volume covered by 95% isodose line was kept as 95%. Results: Average parotid volumes decreased by the mean value of 10% and 6% for the left and right parotids, respectively, and PTV of primary target decreased by mean of 13%. The difference in Dmean doses to parotid glands was 32% and 42% and difference in D50 dose was 30% and 35% on the left and right side, respectively. Conclusions: The parotid volumes differ considerably during adaptive planning done after every ten fractions. These differences in parotid volumes and doses received to parotid glands play a significant role in the risk of xerostomia observed during later follow-up. PMID- 29600238 TI - Efficacy and tolerability of bortezomib and dexamethasone in newly diagnosed multiple myeloma. AB - Background: Outcome in multiple myeloma (MM) has improved substantially over recent years as a result of the availability of multiple novel agents with acceptable safety profile. Study Design: Prospective observational study at a tertiary care institute. Methods: Twenty-five newly diagnosed patients of MM were treated with bortezomib and dexamethasone induction with monitoring for response and safety, followed by peripheral blood autologous stem cell transplant (PBASCT) in eligible patients or maintenance. Results: Out of 25 patients, 32% attained complete response (CR), 56% very good partial response (VGPR), 4% PR, and 8% showed no response. The overall response rate was 92%. In our study, 56% of patients showed hematological side effects, out of which thrombocytopenia was seen in 32%, anemia in 16%, and leukopenia in 8%. Six patients developed bortezomib-induced peripheral neuropathy, out of which four had grade 1 (66.66%), one had grade 2 (16.66%), and 1 (16.66%) had grade 3 toxicity. Sixteen patients were eligible for PBASCT, out of which eight patients received this therapy while as remaining eight patients opted for two more cycles of induction therapy followed by maintenance. After completing 18 months of maintenance, all the eight patients who underwent PBASCT were in CR. Out of the 15 patients who did not receive PBASCT five attained CR, eight VGPR while as two patients relapsed. Conclusion: Bortezomib plus dexamethasone is highly effective and well-tolerated regimen for frontline treatment of MM with a higher quality of response in an advanced stage and renal failure patients. PMID- 29600239 TI - Clinical outcome study of crizotinib in immunohistochemistry-proven echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase fusion gene among Indian patients with adenocarcinoma lung. AB - Aims: The anaplastic lymphoma kinase (ALK) Break Apart FISH Probe Kit and Ventana anti-ALK (D5F3) CDx immunohistochemistry (IHC) assay are the Food and Drug Administration-approved companion diagnostic for targeted therapy with the ALK inhibitor crizotinib in lung cancers. The aim of this study was to assess the efficacy and safety of twice daily crizotinib tablet (250 mg) in IHC-proven echinoderm microtubule-associated protein-like 4 (EML4)-ALK fusion gene among Indian patients with adenocarcinoma lung in the routine clinical practice. Subjects and Methods: Patients with nonsmall cell lung cancer (NSCLC), adenocarcinoma histology, whose tumors were found to be positive for EML4-ALK fusion gene using IHC, were considered for this study. IHC analysis was performed using a Ventana automated immunostainer (Benchmark XT). Detection was performed using Optiview DAB detection and amplification kit. Results: A total of 25 NSCLC adenocarcinoma patients were included in the study. There were 14 (56%) women and 10 (44%) men with a median age of 53 years. All patients had Stage IV disease at the time of initiation of crizotinib therapy. One patient achieved complete response and 20 achieved response rate (PR) for an overall PR of 84%. The median progression-free survival (PFS) was 11.8 months and median overall survival (OS) was 20.6 months. Two (8%) patients experienced severe hepatotoxicity requiring permanent discontinuation of crizotinib therapy. Conclusions: A very high PR, PFS, and OS achieved in our study population indicates that IHC can accurately identify EML4 ALK fusion gene mutations in lung adenocarcinoma patients who are responsive to ALK inhibitors such as crizotinib. IHC should be considered as a cost-effective alternative to FISH, especially in low-resource countries.

PMID- 29600241 TI - A Standardized Needs Assessment Tool to Inform the Curriculum Development Process for Pediatric Resuscitation Simulation-Based Education in Resource-Limited Settings. AB - Introduction: Under five mortality rates (UFMR) remain high for children in low- and middle-income countries (LMICs) in the developing world. Education for practitioners in these environments is a key factor to improve outcomes that will address United Nations Sustainable Development Goals 3 and 10 (good health and well being and reduced inequalities). In order to appropriately contextualize a curriculum using simulation, it is necessary to first conduct a needs assessment of the target learner population. The World Health Organization (WHO) has published a tool to assess capacity for emergency and surgical care in LMICs that is adaptable to this goal. Materials and methods: The WHO Tool for Situational Analysis to Assess Emergency and Essential Surgical Care was modified to assess pediatric resuscitation capacity in clinical settings in two LMICs: Uganda and Myanmar. Modifications included assessment of self-identified learning needs, current practices, and perceived epidemiology of disease burden in each clinical setting, in addition to assessment of pediatric resuscitation capacity in regard to infrastructure, procedures, equipment, and supplies. The modified tool was administered to 94 respondents from the two settings who were target learners of a proposed simulation-based curriculum in pediatric and neonatal resuscitation. Results: Infectious diseases (respiratory illnesses and diarrheal disease) were cited as the most common causes of pediatric deaths in both countries. Self identified learning needs included knowledge and skill development in pediatric airway/breathing topics, as well as general resuscitation topics such as CPR and fluid resuscitation in shock. Equipment and supply availability varied substantially between settings, and critical shortages were identified in each setting. Current practices and procedures were often limited by equipment availability or infrastructural considerations. Discussion and conclusion: Epidemiology of disease burden reported by respondents was relatively consistent with WHO country-specific UFMR statistics in each setting. Results of the needs assessment survey were subsequently used to refine goals and objectives for the simulation curriculum and to ensure delivery of pragmatic educational content with recommendations that were contextualized for local capacity and resource availability. Effective use of the tool in two different settings increases its potential generalizability. PMID- 29600242 TI - Circulatory Insufficiency and Hypotension Related to the Ductus Arteriosus in Neonates. AB - The biological role of the ductus arteriosus (DA) in neonates varies from an innocent bystander role during normal postnatal transition, to a supportive role when there is compromise to either systemic or pulmonary blood flow, to a pathological state in the presence of hemodynamically significant systemic to pulmonary shunts, as occurs in low birth weight infants. Among a wide array of clinical manifestations arising due to the ductal entity, systemic circulatory insufficiency and hypotension are of significant concern as they are particularly challenging to manage. An understanding of the physiologic interplay between the DA and the circulatory system is the key to developing appropriate targeted therapeutic strategies. In this review, we discuss the relationship of systemic hypotension to the DA, emphasizing the importance of critical thinking and a precise individual approach to intensive care support. We particularly focus on the variable states of hypotension arising directly due to a hemodynamically significant DA or seen in the period following successful surgical ligation. In addition, we explore the mechanistic contributions of the ductus to circulatory insufficiency that may manifest during the transitional period, states of maladapted transition (such as acute pulmonary hypertension of the newborn), and congenital heart disease (both ductal dependent and non-ductal dependent lesions). Understanding the dynamic modulator role of the ductus according to the ambient physiology enables a more precise approach to management. We review the pathophysiology, clinical manifestations, diagnosis, monitoring, and therapeutic intervention for the spectrum of DA-related circulatory compromise. PMID- 29600243 TI - Reflections of Homeless Women and Women with Mental Health Challenges on Breast and Cervical Cancer Screening Decisions: Power, Trust, and Communication with Care Providers. AB - This study conducted in Toronto, Canada, explored the perceptions of women living in homeless shelters and women with severe mental health challenges about the factors influencing their decision-making processes regarding breast and cervical cancer screening. Twenty-six in-depth qualitative interviews were conducted. The objectives of this research were (i) to provide new insights about women's decision-making processes, (ii) to describe the barriers to and facilitators for breast and cervical cancer screening, and (iii) to offer recommendations for future outreach, education, and screening initiatives developed specifically for under/never-screened marginalized women living in urban centers. This exploratory study utilized thematic analysis to broaden our understanding about women's decision-making processes. A constructed ontology was used in an attempt to understand and describe participants' constructed realities. The epistemological framework was subjective and reflected co-created knowledge. The approach was hegemonic, values-based, and context-specific. The aim of the analysis was to focus on meanings and actions with a broader view to identify the interplay between participants' narratives and social structures, medical praxis, and policy implications. Results from 26 qualitative interviews conducted in 2013 2014 provided insights on both positive and negative prior cancer screening experiences, the role of power and trust in women's decision-making, and areas for improvement in health care provider/patient interactions. Outcomes of this investigation contribute to the future development of appropriately designed intervention programs for marginalized women, as well as for sensitivity training for health care providers. Tailored and effective health promotion strategies leading to life-long cancer screening behaviors among marginalized women may improve clinical outcomes, decrease treatment costs, and save lives. PMID- 29600244 TI - Extending beyond Policy: Reaching UNAIDS' Three "90"s in Malawi. AB - Malawi, like other countries with a generalized HIV epidemic, is striving to reach the ambitious targets set by UNAIDS known as the three 90's for testing, provision of antiretroviral therapy and viral suppression. Assisted by Malawi's progressive policies on HIV/AIDS, it appears possible that Malawi will attain these targets, but only by employing innovative program approaches to service delivery which help fill policy gaps. This article describes how a dedicated cadre of layperson testers and HIV-positive peers appears to have helped attain increases in HIV and viral load testing and retention in care in four districts in Malawi, and situates these innovations in a policy framework analysis. PMID- 29600245 TI - Viscosity, Conductivity, and Electrochemical Property of Dicyanamide Ionic Liquids. AB - The instructive structure-property relationships of ionic liquids (ILs) can be put to task-specific design of new functionalized ILs. The dicyanamide (DCA) ILs are typical CHN type ILs which are halogen free, chemical stable, low-viscous, and fuel-rich. The transport properties of DCA ionic liquids are significant for their applications as solvents, electrolytes, and hypergolic propellants. This work systematically investigates several important transport properties of four DCA ILs ([C4mim][N(CN)2], [C4m2im][N(CN)2], N4442[N(CN)2], and N8444[N(CN)2]) including viscosity, conductivity, and electrochemical property at different temperatures. The melting points, temperature-dependent viscosities and conductivities reveal the structure-activity relationship of four DCA ILs. From the Walden plots, the imidazolium cations exhibit stronger cation-anion attraction than the ammonium cations. DCA ILs have relatively high values of electrochemical windows (EWs), which indicates that the DCA ILs are potential candidates for electrolytes in electrochemical applications. The cyclic voltammograms of Eu(III) in these DCA ILs at GC working electrode at various temperatures 303-333 K consists of quasi-reversible waves. The electrochemical properties of the DCA ILs are also dominated by the cationic structures. The current intensity (ip), the diffusion coefficients (Do), the charge transfer rate constants (ks) of Eu(III) in DCA ILs all increased with the molar conductivities increased. The cationic structure-transport property relationships of DCA ILs were constructed for designing novel functionalized ILs to fulfill specific demands. PMID- 29600246 TI - Evolution of Sangiovese Wines With Varied Tannin and Anthocyanin Ratios During Oxidative Aging. AB - Changes in phenolic compounds, chromatic characteristics, acetaldehyde, and protein-reactive tannins associated with oxidative aging were studied in Sangiovese wines with varied tannin T/anthocyanin A ratios. For this purpose, three Sangiovese vineyards located in Tuscany were considered in the 2016 vintage. To obtain wines with different T/A ratios, two red wines were produced from each vinification batch: a free run juice with a lower T/A ratio and a marc pressed wine with a higher T/A ratio. An overall of six wines with T/A ratios ranging between 5 and 23 were produced. An oxidation treatment (four saturation cycles) was applied to each wine. Average and initial oxygen consumption rates (OCR) were positively correlated to VRF/mA (vanilline reactive flavans/monomeric anthocyanins) and T/A ratios while OCRs were negatively related to the wine content in monomeric and total anthocyanins. The higher the A content was, the greater the loss of total and free anthocyanins. A significant lower production of polymeric pigments was detected in all pressed wines with respect to the correspondant free run one. A gradual decrease of tannin reactivity toward saliva proteins after the application of oxygen saturation cycles was detected. The results obtained in this experiment indicate that VRF/mA and T/A ratios are among the fundamental parameters to evaluate before choosing the antioxidant protection to be used and the right oxidation level to apply for a longer shelf-life of red wine. PMID- 29600247 TI - The Effects of Combinations of Cognitive Impairment and Pre-frailty on Adverse Outcomes from a Prospective Community-Based Cohort Study of Older Chinese People. AB - Objectives: To examine how various combinations of cognitive impairment (overall performance and specific domains) and pre-frailty predict risks of adverse outcomes; and to determine whether cognitive frailty may be defined as the combination of cognitive impairment and the presence of pre-frailty. Design: Community-based cohort study. Participants: Chinese men and women (n = 3,491) aged 65+ without dementia, Parkinson's disease and/or frailty at baseline. Measurements: Frailty was characterized using the Cardiovascular Health Study criteria. Overall cognitive impairment was defined by a Cantonese Mini-Mental Status Examination (CMMSE) total score (<21/24/27, depending on participants' educational levels); delayed recall impairment by a CMMSE delayed recall score (<3); and language and praxis impairment by a CMMSE language and praxis score (<9). Adverse outcomes included poor quality of life, physical limitation, increased cumulative hospital stay, and mortality. Results: Compared to those who were robust and cognitively intact at baseline, those who were robust but cognitively impaired were more likely to develop pre-frailty/frailty after 4 years (P < 0.01). Compared to participants who were robust and cognitively intact at baseline, those who were pre-frail and with overall cognitive impairment had lower grip strength (P < 0.05), lower gait speed (P < 0.01), poorer lower limb strength (P < 0.01), and poorer delayed recall at year 4 [OR, 1.6; 95% confidence interval (CI), 1.2-2.3]. They were also associated with increased risks of poor quality of life (OR, 1.5; 95% CI, 1.1-2.2) and incident physical limitation at year 4 (OR, 1.8; 95% CI, 1.3-2.5), increased cumulative hospital stay at year 7 (OR, 1.5; 95% CI, 1.1-2.1), and mortality over an average of 12 years (OR, 1.5; 95% CI, 1.0-2.1) after adjustment for covariates. There was no significant difference in risks of adverse outcomes between participants who were pre-frail, with/without cognitive impairment at baseline. Similar results were obtained with delayed recall and language and praxis impairments. Conclusion: Robust and cognitively impaired participants had higher risks of becoming pre-frail/frail over 4 years compared with those with normal cognition. Cognitive impairment characterized by the CMMSE overall score or its individual domain score improved the predictive power of pre-frailty for poor quality of life, incident physical limitation, increased cumulative hospital stay, and mortality. Our findings support to the concept that cognitive frailty may be defined as the occurrence of both cognitive impairment and pre-frailty, not necessarily progressing to dementia. PMID- 29600248 TI - CD11b Activity Modulates Pathogenesis of Lupus Nephritis. AB - Lupus nephritis (LN) is a common complication of systemic lupus erythematosus (SLE) with unclear etiology and limited treatment options. Immune cell infiltration into the kidneys, a hallmark of LN, triggers tissue damage and proteinuria. CD11b, the alpha-chain of integrin receptor CD11b/CD18 (also known as alphaMbeta2, Mac-1, and CR3), is highly expressed on the surface of innate immune cells, including macrophages and neutrophils. Genetic variants in the human ITGAM gene, which encodes for CD11b, are strongly associated with susceptibility to SLE, LN, and other complications of SLE. CD11b modulates several key biological functions in innate immune cells, including cell adhesion, migration, and phagocytosis. CD11b also modulates other signaling pathways in these cells, such as the Toll-like receptor signaling pathways, that mediate generation of type I interferons, a key proinflammatory cytokine and circulating biomarker in SLE and LN patients. However, how variants in ITGAM gene contribute to disease pathogenesis has not been completely established. Here, we provide an overview of CD11b modulated mechanisms and the functional consequences of the genetic variants that can drive disease pathogenesis. We also present recent insights from studies after pharmacological activation of CD11b. These studies offer novel mechanisms for development of therapeutics for LN, SLE and other autoimmune diseases. PMID- 29600249 TI - Human-Induced Pluripotent Stem Cells Manufactured Using a Current Good Manufacturing Practice-Compliant Process Differentiate Into Clinically Relevant Cells From Three Germ Layers. AB - The discovery of reprogramming and generation of human-induced pluripotent stem cells (iPSCs) has revolutionized the field of regenerative medicine and opened new opportunities in cell replacement therapies. While generation of iPSCs represents a significant breakthrough, the clinical relevance of iPSCs for cell based therapies requires generation of high-quality specialized cells through robust and reproducible directed differentiation protocols. We have recently reported manufacturing of human iPSC master cell banks (MCB) under current good manufacturing practices (cGMPs). Here, we describe the clinical potential of human iPSCs generated using this cGMP-compliant process by differentiating them into the cells from all three embryonic germ layers including ectoderm, endoderm, and mesoderm. Most importantly, we have shown that our iPSC manufacturing process and cell culture system is not biased toward a specific lineage. Following controlled induction into a specific differentiation lineage, specialized cells with morphological and cellular characteristics of neural stem cells, definitive endoderm, and cardiomyocytes were developed. We believe that these cGMP-compliant iPSCs have the potential to make various clinically relevant products suitable for cell therapy applications. PMID- 29600250 TI - Relaxase MobM Induces a Molecular Switch at Its Cognate Origin of Transfer. AB - The MOBV1 family of relaxases is broadly distributed in plasmids and other mobile genetic elements isolated from staphylococci, enterococci, and streptococci. The prototype of this family is protein MobM encoded by the streptococcal promiscuous plasmid pMV158. MobM cleaves the phosphodiester bond of a specific dinucleotide within the origin of transfer (oriT) to initiate conjugative transfer. Differently from other relaxases, MobM and probably other members of the family, cleaves its target single-stranded DNA through a histidine residue rather than the commonly used tyrosine. The oriT of the MOBV1 family differs from other well known conjugative systems since it has sequences with three inverted repeats, which were predicted to generate three mutually-exclusive hairpins on supercoiled DNA. In this work, such hypothesis was evaluated through footprinting experiments on supercoiled plasmid DNA. We have found a change in hairpin extrusion mediated by protein MobM. This conformational change involves a shift from the main hairpin generated on "naked" DNA to a different hairpin in which the nick site is positioned in a single-stranded configuration. Our results indicate that the oriTpMV158 acts as a molecular switch in which, depending on the inverted repeat recognized by MobM, pMV158 mobilization could be turned "on" or "off." PMID- 29600252 TI - Is a Single Fecal Microbiota Transplant a Promising Treatment for Recurrent Clostridium difficile Infection? AB - Clostridium difficile infection, a common hospital-associated infection, is a gastrointestinal illness that becomes recurrent in about 25% of infected patients. Fecal microbiota transplantation (FMT) is increasingly supported by clinical trials as an effective treatment for recurrent Clostridium difficile infection, but a number of questions remain about how it can be optimally performed. In this Perspective, we discuss controversies in FMT methodologies and reporting within randomized controlled trials, all of which may influence clinical outcomes in treated patients. Finally, we focus on the question of whether single vs multiple FMTs are necessary to achieve favorable outcomes for the treatment of recurrent Clostridium difficile infection, postulating on why there may be an association between number of FMTs and clinical effectiveness. PMID- 29600251 TI - General cognitive impairment as a risk factor for motor vehicle collision involvement: a prospective population-based study. AB - This study examined whether cognitive impairment and decline as assessed by a brief mental status screening test is associated with future crash risk in a cohort of older drivers. A three-year prospective study was conducted in a population-based sample of 2000 licensed drivers aged 70 years and older. At the baseline visit, cognitive impairment was defined as <24 on the Mini Mental State Exam (MMSE). Decline was defined as those with a 1-year change in MMSE scores in the lowest quartile (largest decrease). Motor vehicle collision involvement was obtained from the Alabama Department of Public Safety. Poisson regression was used to calculate crude and adjusted rate ratios (RR). There were 278 crashes during the follow-up period. Rates of crash involvement were higher for those with cognitive impairment (crude RR=2.33) compared to those without impairment at baseline; adjustment for potential confounders namely age and visual processing speed attenuated this relationship (adjusted RR=1.26, 95% CI 0.65-2.44). Drivers who experienced a pronounced decline in estimated MMSE scores in one year were 1.64 (95% CI 1.04-2.57) times more likely to have a future at-fault crash compared to those whose scores did not decline. Evaluation of MMSE over time may provide important insight in an older driver's future risk of at-fault crash involvement. PMID- 29600253 TI - A Small RNA Isolation and Sequencing Protocol and Its Application to Assay CRISPR RNA Biogenesis in Bacteria. AB - Next generation high-throughput sequencing has enabled sensitive and unambiguous analysis of RNA populations in cells. Here, we describe a method for isolation and strand-specific sequencing of small RNA pools from bacteria that can be multiplexed to accommodate multiple biological samples in a single experiment. Small RNAs are isolated by polyacrylamide gel electrophoresis and treated with T4 polynucleotide kinase. This allows for 3' adapter ligation to CRISPR RNAs, which don't have pre-existing 3'-OH ends. Pre-adenylated adapters are then ligated using T4 RNA ligase 1 in the absence of ATP and with a high concentration of polyethylene glycol (PEG). The 3' capture step enables precise determination of the 3' ends of diverse RNA molecules. Additionally, a random hexamer in the ligated adapter helps control for potential downstream amplification bias. Following reverse-transcription, the cDNA product is circularized and libraries are prepared by PCR. We show that the amplified library need not be visible by gel electrophoresis for efficient sequencing of the desired product. Using this method, we routinely prepare RNA sequencing libraries from minute amounts of purified small RNA. This protocol is tailored to assay for CRISPR RNA biogenesis in bacteria through sequencing of mature CRISPR RNAs, but can be used to sequence diverse classes of small RNAs. We also provide a fully worked example of our data processing pipeline, with instructions for running the provided scripts. PMID- 29600254 TI - Anesthesiology Residency Curriculum and Implementation of a Perioperative Surgical Home Curriculum: A Survey Study. AB - Background: The perioperative surgical home (PSH) is a physician-led, interdisciplinary, and patient-centered model of perioperative care that focuses on patient outcomes and comprehensive care management. Many studies to date have looked at the clinical implementation of varied PSH models with promising results discussed. There are no studies directly examining concrete plans for the various Accreditation Council for Graduate Medical Education (ACGME) anesthesiology residency programs to implement augmented PSH training into curricula. The aim of this survey study was to better assess current residency training in PSH. Methods: An 18-question survey developed by a team of research personnel familiar with the PSH was sent to all ACGME accredited anesthesiology training programs in the United States. Responses were quantified, and construct and external validity of the survey tool examined. Results: 41% of the programs responded. 89% (95% CI 78-96%) of programs reported moderate or better understanding of the PSH. 34% (21 47%) had incorporated additional PSH training in the previous three years, and 32% (with no significant correlation to the previous group) had plans to integrate more training in the next 3 years. Conclusions: Overall, the surveyed program directors voiced understanding of the value of the PSH model in patient care but remained hesitant to incorporate training specific to PSH into the anesthesiology residency curricula. PMID- 29600255 TI - Emergency Manuals Improved Novice Physician Performance During Simulated ICU Emergencies. AB - Background: Emergency manuals, which are safety essentials in non-medical high reliability organizations (e.g., aviation), have recently gained acceptance in critical medical environments. Of the existing emergency manuals in anesthesiology, most are geared towards intraoperative settings. Additionally, most evidence supporting their efficacy focuses on the study of physicians with at least some meaningful experience as a physician. Our aim was to evaluate whether an emergency manual would improve the performance of novice physicians (post-graduate year [PGY] 1 or first year resident) in managing a critical event in the intensive care unit (ICU). Methods: PGY1 interns (n=41) were assessed on the management of a simulated critical event (unstable bradycardia) in the ICU. Participants underwent a group allocation process to either a control group (n=18) or an intervention group (emergency manual provided, n=23). The number of successfully executed treatment and diagnostic interventions completed was evaluated over a ten minute (600 seconds) simulation for each participant. Results: The participants using the emergency manual averaged 9.9/12 (83%) interventions, compared to an average of 7.1/12 (59%) interventions (p < 0.01) in the control group. Conclusions: The use of an emergency manual was associated with a significant improvement in critical event management by individual novice physicians in a simulated ICU patient (23% average increase). PMID- 29600256 TI - Fellowships Represent a Logical Target for Cultivating Research in Academic Anesthesiology. AB - Background: The need for greater emphasis on research contributions in academic anesthesiology has been widely recognized in recent years. Some propose increasing integration of research, including dedicated research time, into ACGME requirements for residency and fellowship training experiences. The h-index, an effective measure of research productivity that takes into account relevance and impact of an author's contributions on discourse within a field, was used to examine whether there are differences in research productivity between non fellowship and fellowship-trained faculty in academic anesthesiology departments. This bibliometric was further used to examine differences in subspecialties, and other specialties of medicine. Methods: Research productivity, as measured by the h-index, was examined using the Scopus database for 508 academic Anesthesiologists practicing in the various subspecialties. Results: There was no statistical difference in research productivity, as measured by the h-index, between non-fellowship and fellowship-trained academic anesthesiologists (2.98+ 0.32 vs. 2.88+-0.31). Critical care anesthesiologists had the highest h-indices (5.78+-1.11), while regional anesthesia and pain medicine practitioners had the lowest values (1.18+-0.32). Unlike in anesthesiology, a sample of physicians from other specialties revealed a statistical difference in h-index between non fellowship and fellowship-trained physicians. Conclusions: Scholarly productivity, as measured by the h-index was similar for fellowship and non fellowship trained anesthesiologists. PMID- 29600257 TI - Developing a Comprehensive Perioperative Education Curriculum for Internal Medicine Residency Training. AB - Background: Patients undergoing surgery are becoming increasingly complex and internists are becoming more involved in their perioperative care. Therefore, new requirements from the ACGME/ABIM necessitate education in this area. We aim to discuss how our institution adapted a perioperative curriculum to fill this need. Methods: Perioperative education is primarily given to the residents during their one month rotation through the General Internal Medicine Consult Service rotation. This is an inpatient rotation that provides perioperative expertise to surgical teams, medicine consultation to medical subspecialty teams, and outpatient preoperative evaluations. Results: Our implementation complies with ACGME/ABIM requirements and ensures that the educational and clinical needs of our institution are met. Conclusions: Developing a new curriculum can be daunting. We hope that this explanation of our approach will aid others who are working to develop an effective perioperative curriculum at their institutions. PMID- 29600258 TI - Nicotine and Anatabine Exposure from Very Low Nicotine Content Cigarettes. AB - Objectives: Research using very low nicotine content (VLNC) cigarettes has shown that participants underreport use of non-study cigarettes. Biomarkers of nicotine exposure could be used to verify compliance with VLNC cigarettes. This study aimed to characterize biomarkers of exposure when participants exclusively use VLNC cigarettes. Methods: 23 participants stayed in a hotel that permitted smoking for 5 days and 4 nights. They were provided 2 packs of VLNC cigarettes each day (0.4 mg of nicotine/g of tobacco; Spectrum cigarettes) and did not have access to other tobacco products. 24-hour urine samples were collected to assess exposure to nicotine and anatabine. Results: After 4 days of exclusive use, the geometric means for urinary total cotinine, total nicotine equivalents (TNE), and anatabine were 1.13 nmol/ml (92% reduction), 3.17 nmol/ml (94% reduction) and 0.0031 nmol/ml (93% reduction). The population estimates of the 95th percentile of cotinine, TNE, and anatabine levels were 2.69, 6.41, and 0.0099 nmol/ml, respectively. Conclusions: Study participants exclusively smoking 0.4 mg/g Spectrum cigarettes are unlikely to have biomarker values above these levels. The data presented here will be valuable to researchers conducting research on use of VLNC cigarettes.

The purpose of this paper is to compare body height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see which biomarker is a better predictor for preoperative planning to determine implant size. Methods: A total of 100 knees, belonging to 50 females and 50 males, were observed. Participants' body height and shoe size were collected and correlated to implant sizes of a current, frequently used, standard total knee replacement (TKR) implant. The femoral anteroposterior and mediolateral width and the tibial anteroposterior and mediolateral width were correlated with height and shoe size. Results: The correlation between shoe size and the four knee implant dimensions, femoral AP, ML, and tibial AP and ML were higher than the correlations between height and the same four dimensions. Conclusion: The results indicated that shoe size is a better predictor of component dimensions than is body height.Level of evidence: III. PMID- 29600262 TI - The Stabilising Effect of the Anterior Oblique Ligament to Prevent Directional Subluxation at the Trapeziometacarpal Joint of the Thumb: A Biomechanical Cadaveric Study. AB - Background: The trapeziometacarpal joint (TMCJ) is inherently unstable, relying on ligament restraint to prevent subluxation. Subluxation of the thumb in a dorsoradial direction is often observed in clinical practice, either after acute ligament injury or more commonly with osteoarthritis (OA). This subluxation follows loss of function of trapeziometacarpal ligaments that stabilise this joint, resisting the deforming force of abductor pollicis longus (APL). The exact ligaments that stabilise and prevent the thumb from the pull of APL causing dorsoradial subluxation remain unknown, although the anterior oblique ligament (AOL) has been implicated. The aim of this study was to measure the direction of subluxation resisted by the AOL. Methods: In this study we used cadaveric limbs and custom made biomechanical testing to measure the influence AOL has in stabilising the thumb against subluxation in three planes: radial, dorsal and dorsoradial. Three fresh frozen hands were dissected to expose the TMCJ, leaving all ligaments, capsule and APL attachment in place. The force required to create a displacement of 5mm between the first metacarpal and the trapezium in these three planes was measured before and after AOL division. Results: The average force to displace in the dorsoradial plane prior to division was 6.68N, and a statistically significant reduction to 1.15N (P<0.001) was found after division of the AOL. A statistically significant increase in force (P<0.001) from 2.89N to 4.04N was seen in the radial plane, while no change was seen dorsally (P=0.98), with average forces of 2.74N and 2.62N found pre and post division. Conclusion: There is clinical significance in reporting quantifiable data in this field, as subluxation of the thumb is often seen with OA. The results of our study provide support for surgical reconstruction of the AOL as the primary surgical stabilizer against dorsoradial subluxation of the thumb.Level of evidence: III. PMID- 29600260 TI - Current Concepts in Scaffolding for Bone Tissue Engineering. AB - Bone disorders are of significant worry due to their increased prevalence in the median age. Scaffold-based bone tissue engineering holds great promise for the future of osseous defects therapies. Porous composite materials and functional coatings for metallic implants have been introduced in next generation of orthopedic medicine for tissue engineering. While osteoconductive materials such as hydroxyapatite and tricalcium phosphate ceramics as well as some biodegradable polymers are suggested, much interest has recently focused on the use of osteoinductive materials like demineralized bone matrix or bone derivatives. However, physiochemical modifications in terms of porosity, mechanical strength, cell adhesion, biocompatibility, cell proliferation, mineralization and osteogenic differentiation are required. This paper reviews studies on bone tissue engineering from the biomaterial point of view in scaffolding. Level of evidence: I. PMID- 29600263 TI - Combination of High Tibial Osteotomy and Autologous Bone Marrow Derived Cell Implantation in Early Osteoarthritis of Knee: A Preliminary Study. AB - Background: High tibial osteotomy (HTO) is a recommended treatment for medial compartment knee osteoarthritis. Newer cartilage regenerative procedures may add benefits to the results of HTO. In this prospective study we have investigated the safety and also results of HTO associated with autologous bone marrow derived cells (BMDC) implantation in relatively young and middle aged active individuals with early osteoarthritis of the knee. Methods: A total of 24 patients (mean age of 47.9 years) with varus knee and symptomatic medial compartment osteoarthritis were treated with medial opening-wedge high tibial osteotomy in conjunction with implantation of bone marrow derived cells into the chondral lesions. The clinical outcomes were assessed by IKDC, KOOS, VAS, and Tegner scores. The radiographic studies were performed preoperatively and at follow-ups. Results: No major complications were seen during the operations and postoperative follow-ups. All clinical scores were significantly improved for the IKDC score (from 32.7+/-15 to 64+/-21) (P<0.005), KOOS score (from30+/-11 to 68+/-19) (P<0.005), VAS (from 7.5 to 3) and Tegner score (from 1.2 to 2.1) (P<0.004). Conclusion: HTO in conjunction with BMDC implantation is a safe and feasible treatment and is associated with good results in short term follow up for early medial compartment osteoarthritis in varus knees.Level of evidence: IV. PMID- 29600264 TI - Reliability and Validity of the Swiss Spinal Stenosis Questionnaire for Iranian Patients with Lumbar Spinal Stenosis. AB - Background: The purpose of this study was validation of the Persian translation of the Swiss Spinal Stenosis Questionnaire in order to be used by Iranian researchers. Methods: A total of 104 patients with spinal stenosis diagnosis, who were candidates for operative treatment were entered into the study. The patients completed the translated questionnaire in the 1st and the 7th days of admission and 6 months after surgery. Visual analogue scale was used to determine the severity of the pain in the1st day and the 6th month. Discriminant validity, convergent validity, test-retest reliability, internal consistency, ability to detect changes and sensitivity to clinical changes were assessed for the statistical purposes. Results: Cronbach's alpha was more than 0.9 for all the items. ICC was about 0.9 for all the items. For symptoms, physical and total items, Cronbach's alpha was 0.942, 0.957, 0.926 and Intraclass correlation were 0.891, 0.918, 0.862, respectively. Paired t-test was significantly different between the 1st day and the 6th month questionnaire. There was a positive correlation either between the first VAS and the 1st day questionnaire (1st day Q) (r=0.892, P=0.000) or between the 6th month VAS and 6th month Q (r=0.940, P=0.000). The Pearson's correlation between the difference of the total scores of the 1st day and the 6th month and satisfaction score after surgery showed negative correlation (r= -0.746, P=0.000). The effect size was 2.55. Conclusion: The Iranian version of the Swiss Spinal Stenosis has excellent internal consistency, excellent reliability, good ability to alter with changes, especially parallel with clinical improvement, excellent ability to detect changes, and well either convergent or discriminant validity.Level of evidence: II. PMID- 29600265 TI - Comparison of Clinical Results between Patellar Resurfacing and Non-resurfacing in Total Knee Arthroplasty: A Short Term Evaluation. AB - Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for knee osteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare the short-term clinical outcomes of TKA performed with and without the patella resurfacing. Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were randomized to receive patellar resurfacing (n=24; resurfaced group) or to retain their native patella (n=26; non-resurfaced group) based on envelope selection and provided informed consent. Disease specific outcomes including Knee Society Score (KSS), Knee Society Function Score (KSKS-F), Kujala Anterior Knee Pain Scale (AKPS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Short Form 36 (SF-36), and functional patella-related activities were measured within six months of follow-up. Results: There was no significant difference between the resurfaced and non-resurfaced groups in pre and post operative improvement of range of motion (ROM) (P=0.421), KSS (P=0.782, P=0.553), KSKS-F (P=0.241, P=0.293), AKPS (P=0.128, P=0.443), WOMAC (P=0.700, P=0.282), and pain scores (P=0.120, P=0.508). There was no difference in ROM between resurfaced and non-resurfaced group pre (15.24 degrees and 15.45 degrees ) and post operative (18.48 degrees and 18.74). No side effects related to patella was observed in any of the groups. Revision was required in none of the participants. Conclusion: The results showed no significant difference between patellar resurfacing and non-resurfacing in TKA for all outcome measures in a short term.Level of evidence: I.

AB - Background: Good clinical outcome and return to sport and daily functions after anatomical arthroscopic anterior cruciate ligament (ACL) reconstruction is goal standard in this surgery. but to date, there are different challenging issues between orthopedic surgeons regarding graft selection and surgical techniques. Methods: We retrospectively reviewed the patients who underwent anatomical arthroscopic one bundle ACL reconstruction with quadruple hamstring tendon autograft from 2010 to 2016 in our orthopedic sport medicine center. Eighty-two eligible patients (82 knees) who had met our inclusion criteria were examined in terms of knee stability by clinical examinations and KT 2000 arthrometer and - also were evaluated regarding variables related to their health and knee status with a mean 48months follow-up. Results: Seventy-seven patients (93.9%) were male and the other 5 cases (6.1%) were female. The mean age was 33 +/- 8.06 years old at the time of surgery and mean BMI amount was 26.81 +/- 3.72. 78 patients (95%) returned to pre-injury sport activity level after ACL reconstruction and two patients (2.4%) had re-rupture. 63 patients (76.8%) had negative anterior drawer and 67patients (81.8%) negative lachman tests respectively. 10 patients (13%) were found to have positive pivot shift tests which was correlated with pain and a less KOOS scores with a significant difference (P= 0.03). 72 patients (87%) had negative tests in active and 70 (85.4%) had less than 3 mm side to side difference in manual testing by KT2000. Final KOOS score was 70.87 +/- 19.76. Mean Lysholm score was 90 +/- 4.77. Mean International Knee Documentation Committee (IKDC) score of this study was 85 +/- 14.11.Patients who had concomitant partial meniscectomy had significantly lower IKDC scores (P<0.01).Mean kujala score was 79 +/- 3.07. Conclusion: The use of quadrupled hamstring tendon autograft besides the most important part of the treatment which is the surgical technique would yield to excellent results in ACL reconstruction both subjectively and objectively. In addition, patient selection and surgeon's experience should be considered in determining the treatment plan for the patients.Level of evidence: IV. PMID- 29600267 TI - Epineural Sleeve Reconstruction Technique for Median Nerve Complete Transection. AB - In microsurgical nerve repair, the epineural sleeve technique can be used to bridge short nerve defects and to cover the coaptation site with the epineurium of the nerve stump. The epineurium serves as a mechanical aid to reduce gap size, and increase repair strength, effectively assisting nerve regeneration. This article presents a 32-year-old patient who experienced complete transection of the median nerve at the distal forearm, which was treated with the epineural sleeve graft reconstruction technique. Nerve regeneration was followed-up for 18 months and evaluated with the Rosen and Lundborg scoring system. The final outcome was excellent; at the last follow-up, the patient experienced complete sensory and motor function of the median nerve. Level of evidence: V. PMID- 29600268 TI - Healing of Complete Tear of the Anterior Talofibular Ligament and Early Ankle Stabilization after Autologous Platelet Rich Plasma: a Case Report and Literature Review. AB - Lateral Ankle sprain (LAS) is a common sports injury associated with recurrent ankle sprain, chronic ankle instability (CAI) and post-traumatic ankle osteoarthritis (PTOA). Platelet Rich Plasma (PRP) has been increasingly used for herapeutic applications in sports-related injuries, and is thought to stimulate tissue healing. We reported a case of LAS with complete tear of anterior talofibular ligament, which showed complete healing of ligament and early ankle stabilization after PRP. The healing is supported by dynamic ultrasound images and magnetic resonance imaging. We therefore proposed that PRP may serve as an alternative non-surgical treatment option in LAS in future research, with the potential to prevent the development of CAI and PTOA.

Physical examination and nerve conduction study were consistent with injury to the median and radial nerves proximal to the elbow. The patient underwent open reduction and internal fixation of the humeral shaft fracture with neurolysis of the median and radial nerves. Repeat electromyography at 6 months postoperatively showed recruitment of motor units in all muscles sampled, in keeping with clinical improvement. At 16 months follow up, the patient was full strength in all muscle groups, was back to all activities with no restrictions, and was discharged from follow-up. Our case describes clinical improvement after surgical intervention in a patient with combined median and radial nerve palsies following distal humeral shaft fracture. Level of evidence: V.

AB - The Earth-Moon system likely formed as a result of a collision between two large planetary objects. Debate about their relative masses, the impact energy involved, and the extent of isotopic homogenization continues. We present the results of a high-precision oxygen isotope study of an extensive suite of lunar and terrestrial samples. We demonstrate that lunar rocks and terrestrial basalts show a 3 to 4 ppm (parts per million), statistically resolvable, difference in Delta17O. Taking aubrite meteorites as a candidate impactor material, we show that the giant impact scenario involved nearly complete mixing between the target and impactor. Alternatively, the degree of similarity between the Delta17O values of the impactor and the proto-Earth must have been significantly closer than that between Earth and aubrites. If the Earth-Moon system evolved from an initially highly vaporized and isotopically homogenized state, as indicated by recent dynamical models, then the terrestrial basalt-lunar oxygen isotope difference detected by our study may be a reflection of post-giant impact additions to Earth. On the basis of this assumption, our data indicate that post-giant impact additions to Earth could have contributed between 5 and 30% of Earth's water, depending on global water estimates. Consequently, our data indicate that the bulk of Earth's water was accreted before the giant impact and not later, as often proposed. PMID- 29600272 TI - A climate-associated multispecies cryptic cline in the northwest Atlantic. AB - The spatial genetic structure of most species in the open marine environment remains largely unresolved. This information gap creates uncertainty in the sustainable management, recovery, and associated resilience of marine communities and our capacity to extrapolate beyond the few species for which such information exists. We document a previously unidentified multispecies biogeographic break aligned with a steep climatic gradient and driven by seasonal temperature minima in the northwest Atlantic. The coherence of this genetic break across our five study species with contrasting life histories suggests a pervasive macroecological phenomenon. The integration of this genetic structure with habitat suitability models and climate forecasts predicts significant variation in northward distributional shifts among populations and availability of suitable habitat in future oceans. The results of our integrated approach provide new perspective on how cryptic intraspecific diversity associated with climatic variation influences species and community response to climate change beyond simple poleward shifts. PMID- 29600273 TI - The photoreactive free radical in eumelanin. AB - Melanin is the primary photoprotecting pigment in humans as well as being implicated in the development of deadly melanoma. The material also conducts electricity and has thus become a bioelectronic model for proton-to-electron transduction. Central to these phenomena are its spin properties-notably two linked species derived from carbon-centered and semiquinone radicals. Using a novel in situ photoinduced electron paramagnetic resonance technique with simultaneous electrical measurements, we have elucidated for the first time the distinct photoreactivity of the two different radical species. We find that the production of the semiquinone is light- and water-driven, explaining the electrical properties and revealing biologically relevant photoreactivity.

PMID- 29600275 TI - Ataxia-telangiectasia: A new remitting form with a peculiar transcriptome signature. AB - Objective: Ataxia-telangiectasia (AT) is a rare, severe, and ineluctably progressive multisystemic neurodegenerative disease. Variant AT phenotypes have been described in patients with mild- and late-onset neurologic deterioration and atypical features (dystonia and myoclonus). We report on the clinical characteristics and transcriptome profile of patients with a typical AT presentation and genotype who experienced an unexpected favorable course. Methods: A 24-year-old woman developed, by the age of 3 years, all the classic symptoms of AT associated with increased alpha-fetoprotein levels, a compound AT mutated (ATM) genotype with an inframe deletion c.2250G>A (p.Glu709_Lys750del42) and a missense mutation c.8122G>A (p.Asp2708Gln), and no residual ATM protein expression. By the age of 12 years, ataxia slowly disappeared, and a very mild choreic disorder was the only neurologic feature in adulthood. Brain MRI was normal. The blood transcriptome profile was assessed and compared with that of healthy controls and patients with the classic AT phenotype. Results: The atypical clinical course of the patient was associated with a transitional transcriptome profile: while 90% of transcripts were expressed as in patients with the classic AT presentation, 10% of transcripts were expressed as in healthy controls. Conclusions: The unexpected mild clinical outcome and transcriptome profile of this patient with AT suggest the existence of individual resilience to the altered ATM synthesis. Because of their possible prognostic and therapeutic implications, the identification of modifier factors affecting the phenotype would deserve further studies. PMID- 29600276 TI - Diagnostic odyssey of patients with mitochondrial disease: Results of a survey. AB - Objective: To document the complex "diagnostic odyssey" of patients with mitochondrial disease. Methods: We analyzed data from 210 Rare Diseases Clinical Research Network Contact Registry participants who were patients with a biochemical deficiency or self-reported diagnosis of mitochondrial disease, or their caregivers. Results: Participants saw an average of 8.19 clinicians (SD 8.0, median 5). The first clinician consulted about symptoms was typically a primary care physician (56.7%), although 35.2% of participants initially sought a specialist. Of note, 55.2% of participants received their diagnosis from a neurologist, 18.2% from a clinical geneticist, and 11.8% from a metabolic disease specialist. A majority of the participants (54.6%) received 1 or more nonmitochondrial diagnoses before their final mitochondrial diagnosis. In their pursuit of a diagnosis, 84.8% of participants received blood tests, 71% a muscle biopsy, 60.5% MRI, and 38.6% urine organic acids. In addition, 39.5% of the participants underwent mitochondrial DNA sequencing, 19% sequencing of nuclear gene(s), and 11.4% whole-exome sequencing. Conclusions: The diagnostic odyssey of patients with mitochondrial disease is complex and burdensome. It features multiple consultations and tests, and, often, conflicting diagnoses. These reflect disease variety, diagnostic uncertainty, and clinician unfamiliarity. The current survey provides an important benchmark. Its replication at appropriate intervals will assist in tracking changes that may accompany increased popularity of exome testing, more rigorous diagnostic criteria, increased patient reported outcome activity, and trials for promising therapies.

PMID- 29600278 TI - Shifts in the Gut Metabolome and Clostridium difficile Transcriptome throughout Colonization and Infection in a Mouse Model. AB - Antibiotics alter the gut microbiota and decrease resistance to Clostridium difficile colonization; however, the mechanisms driving colonization resistance are not well understood. Loss of resistance to C. difficile colonization due to antibiotic treatment is associated with alterations in the gut metabolome, specifically, with increases in levels of nutrients that C. difficile can utilize for growth in vitro. To define the nutrients that C. difficile requires for colonization and pathogenesis in vivo, we used a combination of mass spectrometry and RNA sequencing (RNA Seq) to model the gut metabolome and C. difficile transcriptome throughout an acute infection in a mouse model at the following time points: 0, 12, 24, and 30 h. We also performed multivariate-based integration of the omics data to define the signatures that were most important throughout colonization and infection. Here we show that amino acids, in particular, proline and branched-chain amino acids, and carbohydrates decrease in abundance over time in the mouse cecum and that C. difficile gene expression is consistent with their utilization in vivo. This was also reinforced by the multivariate-based integration of the omics data where we were able to discriminate the metabolites and transcripts that support C. difficile physiology between the different time points throughout colonization and infection. This report illustrates how important the availability of amino acids and other nutrients is for the initial stages of C. difficile colonization and progression of disease. Future studies identifying the source of the nutrients and engineering bacteria capable of outcompeting C. difficile in the gut will be important for developing new targeted bacterial therapeutics. IMPORTANCE Clostridium difficile is a bacterial pathogen of global significance that is a major cause of antibiotic-associated diarrhea. Antibiotics deplete the indigenous gut microbiota and change the metabolic environment in the gut to one favoring C. difficile growth. Here we used metabolomics and transcriptomics to define the gut environment after antibiotics and during the initial stages of C. difficile colonization and infection. We show that amino acids, in particular, proline and branched-chain amino acids, and carbohydrates decrease in abundance over time and that C. difficile gene expression is consistent with their utilization by the bacterium in vivo. We employed an integrated approach to analyze the metabolome and transcriptome to identify associations between metabolites and transcripts. This highlighted the importance of key nutrients in the early stages of colonization, and the data provide a rationale for the development of therapies based on the use of bacteria that specifically compete for nutrients that are essential for C. difficile colonization and disease. PMID- 29600279 TI - Intracellular Trafficking and Persistence of Acinetobacter baumannii Requires Transcription Factor EB. AB - Acinetobacter baumannii is a significant human pathogen associated with hospital acquired infections. While adhesion, an initial and important step in A. baumannii infection, is well characterized, the intracellular trafficking of this pathogen inside host cells remains poorly studied. Here, we demonstrate that transcription factor EB (TFEB) is activated after A. baumannii infection of human lung epithelial cells (A549). We also show that TFEB is required for the invasion and persistence inside A549 cells. Consequently, lysosomal biogenesis and autophagy activation were observed after TFEB activation which could increase the death of A549 cells. In addition, using the Caenorhabditis elegans infection model by A. baumannii, the TFEB orthologue HLH-30 was required for survival of the nematode to infection, although nuclear translocation of HLH-30 was not required. These results identify TFEB as a conserved key factor in the pathogenesis of A. baumannii. IMPORTANCE Adhesion is an initial and important step in Acinetobacter baumannii infections. However, the mechanism of entrance and persistence inside host cells is unclear and remains to be understood. In this study, we report that, in addition to its known role in host defense against Gram-positive bacterial infection, TFEB also plays an important role in the intracellular trafficking of A. baumannii in host cells. TFEB was activated shortly after A. baumannii infection and is required for its persistence within host cells. Additionally, using the C. elegans infection model by A. baumannii, the TFEB orthologue HLH-30 was required for survival of the nematode to infection, although nuclear translocation of HLH-30 was not required. PMID- 29600280 TI - Reproductive System Symbiotic Bacteria Are Conserved between Two Distinct Populations of Euprymna scolopes from Oahu, Hawaii. AB - Female Hawaiian bobtail squid, Euprymna scolopes, harbor a symbiotic bacterial community in a reproductive organ, the accessory nidamental gland (ANG). This community is known to be stable over several generations of wild-caught bobtail squid but has, to date, been examined for only one population in Maunalua Bay, Oahu, HI. This study assessed the ANG and corresponding egg jelly coat (JC) bacterial communities for another genetically isolated host population from Kaneohe Bay, Oahu, HI, using 16S amplicon sequencing. The bacterial communities from the ANGs and JCs of the two populations were found to be similar in richness, evenness, phylogenetic diversity, and overall community composition. However, the Kaneohe Bay samples formed their own subset within the Maunalua Bay ANG/JC community. An Alteromonadaceae genus, BD2-13, was significantly higher in relative abundance in the Kaneohe Bay population, and several Alphaproteobacteria taxa also shifted in relative abundance between the two groups. This variation could be due to local adaptation to differing environmental challenges, to localized variability, or to functional redundancy among the ANG taxa. The overall stability of the community between the populations further supports a crucial functional role that has been hypothesized for this symbiosis. IMPORTANCE In this study, we examined the reproductive ANG symbiosis found in two genetically isolated populations of the Hawaiian bobtail squid, Euprymna scolopes. The stability of the community reported here provides support for the hypothesis that this symbiosis is under strong selective pressure, while the observed differences suggest that some level of local adaptation may have occurred. These two host populations are frequently used interchangeably as source populations for research. Euprymna scolopes is an important model organism and offers the opportunity to examine the interplay between a binary and a consortial symbiosis in a single model host. Understanding the inherent natural variability of this association will aid in our understanding of the conservation, function, transmission, and development of the ANG symbiosis.

Here we add to the collection of disruption markers to aid in genetic analysis of this yeast. This new construct is marked with a nourseothricin resistance cassette that produces an estrogen-activated form of Cre recombinase in a methionine-regulated manner. This allows eviction and reuse of this cassette in a facile manner. Using this new disruption marker, we have constructed a series of strains lacking different members of the major facilitator superfamily (MFS) of membrane transporter proteins. The presence of 15 MFS proteins that may contribute to drug resistance in C. glabrata placed a premium on development of a marker that could easily be reused to construct multiple gene-disrupted strains. Employing this recyclable marker, we found that loss of the MFS transporter encoding gene FLR1 caused a dramatic increase in diamide resistance (as seen before), and deletion of two other MFS-encoding genes did not influence this phenotype. Interestingly, loss of FLR1 led to an increase in levels of oxidized glutathione, suggesting a possible molecular explanation for this enhanced oxidant sensitivity. We also found that while overproduction of the transcription factor Yap1 could suppress the fluconazole sensitivity caused by loss of the important ATP-binding cassette transporter protein Cdr1, this required the presence of FLR1. IMPORTANCE Export of drugs is a problem for chemotherapy of infectious organisms. A class of membrane proteins called the major facilitator superfamily contains a large number of proteins that often elevate drug resistance when overproduced but do not impact this phenotype when the gene is removed. We wondered if this absence of a phenotype for a disruption allele might be due to the redundancy of this group of membrane proteins. We describe the production of an easy-to-use recyclable marker cassette that will allow construction of strains lacking multiple members of the MFS family of transporter proteins. PMID- 29600282 TI - Investigating Colonization of the Healthy Adult Gastrointestinal Tract by Fungi. AB - A wide diversity of fungi have been detected in the human gastrointestinal (GI) tract with the potential to provide or influence important functions. However, many of the fungi most commonly detected in stool samples are also present in food or the oral cavity. Therefore, to recognize which gut fungi are likely to have a sustained influence on human health, there is a need to separate transient members of the GI tract from true colonizers. To identify colonizing fungi, the eukaryotic rRNA operon's second internal transcribed spacer (ITS2) was sequenced from the stool, saliva, and food of healthy adults following consumption of different controlled diets. Unlike most bacterial 16S rRNA genes, the only fungal ITS2 operational taxonomic units (OTUs) detected in stool DNA across multiple diets were also present in saliva and/or food. Additional analyses, including culture-based approaches and sequencing of the 18S rRNA gene, ITS2 cDNA, and DNA extracted using alternative methods, failed to detect additional fungi. Two abundant fungi, Saccharomyces cerevisiae and Candida albicans, were examined further in healthy volunteers. Saccharomyces became undetectable in stool when a S. cerevisiae-free diet was consumed, and the levels of C. albicans in stool were dramatically reduced by more frequent cleaning of teeth. Extremely low fungal abundance, the inability of fungi to grow under conditions mimicking the distal gut, and evidence from analysis of other public datasets further support the hypothesis that fungi do not routinely colonize the GI tracts of healthy adults. IMPORTANCE We sought to identify the fungi that colonize healthy GI tracts and that have a sustained influence on the diverse functions of the gut microbiome. Instead, we found that all fungi in the stool of healthy volunteers could be explained by their presence in oral and dietary sources and that our results, together with those from other analyses, support the model that there is little or no gastrointestinal colonization by fungi. This may be due to Westernization, primate evolution, fungal ecology, and/or the strong defenses of a healthy immune system. Importantly, fungal colonization of the GI tract may often be indicative of disease. As fungi can cause serious infections in immunocompromised individuals and are found at increased abundance in multiple disorders of the GI tract, understanding normal fungal colonization is essential for proper treatment and prevention of fungal pathogenesis. PMID- 29600284 TI - Assembly, Biochemical Characterization, Immunogenicity, Adjuvanticity, and Efficacy of Shigella Artificial Invaplex. AB - The native Invaplex (InvaplexNAT) vaccine and adjuvant is an ion exchange purified product derived from the water extract of virulent Shigella species. The key component of InvaplexNAT is a high-molecular-mass complex (HMMC) consisting of the Shigella lipopolysaccharide (LPS) and the invasin proteins IpaB and IpaC. To improve product purity and immunogenicity, artificial Invaplex (InvaplexAR) was developed using recombinant IpaB and IpaC proteins and purified Shigella LPS to assemble an HMMC consisting of all three components. Characterization of InvaplexAR by various methods demonstrated similar characteristics as the previously reported HMMC in InvaplexNAT. The well-defined InvaplexAR vaccine consistently contained greater quantities of IpaB, IpaC, and LPS than InvaplexNAT. InvaplexAR and InvaplexNAT immunogenicities were compared in mouse and guinea pig dose escalation studies. In both models, immunization induced antibody responses specific for InvaplexNAT and LPS while InvaplexAR induced markedly higher anti-IpaB and -IpaC serum IgG and IgA endpoint titers. In the murine model, homologous protection was achieved with 10-fold less InvaplexAR than InvaplexNAT and mice receiving InvaplexAR lost significantly less weight than mice receiving the same amount of InvaplexNAT. Moreover, mice immunized with InvaplexAR were protected from challenge with both homologous and heterologous Shigella serotypes. Guinea pigs receiving approximately 5-fold less InvaplexAR compared to cohorts immunized with InvaplexNAT were protected from ocular challenge. Furthermore, adjuvanticity previously attributed to InvaplexNAT was retained with InvaplexAR. The second-generation Shigella Invaplex vaccine, InvaplexAR, offers significant advantages over InvaplexNAT in reproducibility, flexible yet defined composition, immunogenicity, and protective efficacy. IMPORTANCEShigella species are bacteria that cause severe diarrheal disease worldwide, primarily in young children. Treatment of shigellosis includes oral fluids and antibiotics, but the high burden of disease, increasing prevalence of antibiotic resistance, and long-term health consequences clearly warrant the development of an effective vaccine. One Shigella vaccine under development is termed the invasin complex or Invaplex and is designed to drive an immune response to specific antigens of the bacteria in an effort to protect an individual from infection. The work presented here describes the production and evaluation of a new generation of Invaplex. The improved vaccine stimulates the production of antibodies in immunized mice and guinea pigs and protects these animals from Shigella infection. The next step in the product's development will be to test the safety and immune response induced in humans immunized with Invaplex. PMID- 29600283 TI - Zika Virus Infection Preferentially Counterbalances Human Peripheral Monocyte and/or NK Cell Activity. AB - Zika virus (ZIKV) has reemerged in the population and caused unprecedented global outbreaks. Here, the transcriptomic consequences of ZIKV infection were studied systematically first in human peripheral blood CD14+ monocytes and monocyte derived macrophages with high-density RNA sequencing. Analyses of the ZIKV genome revealed that the virus underwent genetic diversification, and differential mRNA abundance was found in host cells during infection. Notably, there was a significant change in the cellular response, with cross talk between monocytes and natural killer (NK) cells as one of the highly identified pathways. Immunophenotyping of peripheral blood from ZIKV-infected patients further confirmed the activation of NK cells during acute infection. ZIKV infection in peripheral blood cells isolated from healthy donors led to the induction of gamma interferon (IFN-gamma) and CD107a-two key markers of NK cell function. Depletion of CD14+ monocytes from peripheral blood resulted in a reduction of these markers and reduced priming of NK cells during infection. This was complemented by the immunoproteomic changes observed. Mechanistically, ZIKV infection preferentially counterbalances monocyte and/or NK cell activity, with implications for targeted cytokine immunotherapies. IMPORTANCE ZIKV reemerged in recent years, causing outbreaks in many parts of the world. Alarmingly, ZIKV infection has been associated with neurological complications such as Guillain-Barre syndrome (GBS) in adults and congenital fetal growth-associated anomalies in newborns. Host peripheral immune cells are one of the first to interact with the virus upon successful transmission from an infected female Aedes mosquito. However, little is known about the role of these immune cells during infection. In this work, the immune responses of monocytes, known target cells of ZIKV infection, were investigated by high-density transcriptomics. The analysis saw a robust immune response being elicited. Importantly, it also divulged that monocytes prime NK cell activities during virus infection. Removal of monocytes during the infection changed the immune milieu, which in turn reduced NK cell stimulation. This study provides valuable insights into the pathobiology of the virus and allows for the possibility of designing novel targeted therapeutics. PMID- 29600285 TI - Developing a Bacteroides System for Function-Based Screening of DNA from the Human Gut Microbiome. AB - Functional metagenomics is a powerful method that allows the isolation of genes whose role may not have been predicted from DNA sequence. In this approach, first, environmental DNA is cloned to generate metagenomic libraries that are maintained in Escherichia coli, and second, the cloned DNA is screened for activities of interest. Typically, functional screens are carried out using E. coli as a surrogate host, although there likely exist barriers to gene expression, such as lack of recognition of native promoters. Here, we describe efforts to develop Bacteroides thetaiotaomicron as a surrogate host for screening metagenomic DNA from the human gut. We construct a B. thetaiotaomicron-compatible fosmid cloning vector, generate a fosmid clone library using DNA from the human gut, and show successful functional complementation of a B. thetaiotaomicron glycan utilization mutant. Though we were unable to retrieve the physical fosmid after complementation, we used genome sequencing to identify the complementing genes derived from the human gut microbiome. Our results demonstrate that the use of B. thetaiotaomicron to express metagenomic DNA is promising, but they also exemplify the challenges that can be encountered in the development of new surrogate hosts for functional screening. IMPORTANCE Human gut microbiome research has been supported by advances in DNA sequencing that make it possible to obtain gigabases of sequence data from metagenomes but is limited by a lack of knowledge of gene function that leads to incomplete annotation of these data sets. There is a need for the development of methods that can provide experimental data regarding microbial gene function. Functional metagenomics is one such method, but functional screens are often carried out using hosts that may not be able to express the bulk of the environmental DNA being screened. We expand the range of current screening hosts and demonstrate that human gut derived metagenomic libraries can be introduced into the gut microbe Bacteroides thetaiotaomicron to identify genes based on activity screening. Our results support the continuing development of genetically tractable systems to obtain information about gene function. PMID- 29600286 TI - From Network Analysis to Functional Metabolic Modeling of the Human Gut Microbiota. AB - An important hallmark of the human gut microbiota is its species diversity and complexity. Various diseases have been associated with a decreased diversity leading to reduced metabolic functionalities. Common approaches to investigate the human microbiota include high-throughput sequencing with subsequent correlative analyses. However, to understand the ecology of the human gut microbiota and consequently design novel treatments for diseases, it is important to represent the different interactions between microbes with their associated metabolites. Computational systems biology approaches can give further mechanistic insights by constructing data- or knowledge-driven networks that represent microbe interactions. In this minireview, we will discuss current approaches in systems biology to analyze the human gut microbiota, with a particular focus on constraint-based modeling. We will discuss various community modeling techniques with their advantages and differences, as well as their application to predict the metabolic mechanisms of intestinal microbial communities. Finally, we will discuss future perspectives and current challenges of simulating realistic and comprehensive models of the human gut microbiota. PMID- 29600287 TI - luxR Homolog-Linked Biosynthetic Gene Clusters in Proteobacteria. AB - Microbes are a major source of antibiotics, pharmaceuticals, and other bioactive compounds. The production of many specialized microbial metabolites is encoded in biosynthetic gene clusters (BGCs). A challenge associated with natural product discovery is that many BGCs are not expressed under laboratory growth conditions. Here we report a genome-mining approach to discover BGCs with luxR-type quorum sensing (QS) genes, which code for regulatory proteins that control gene expression. Our results show that BGCs linked to genes coding for LuxR-like proteins are widespread in Proteobacteria. In addition, we show that associations between luxR homolog genes and BGCs have evolved independently many times, with functionally diverse gene clusters. Overall, these clusters may provide a source of new natural products for which there is some understanding about how to elicit production. IMPORTANCE Bacteria biosynthesize specialized metabolites with a variety of ecological functions, including defense against other microbes. Genes that code for specialized metabolite biosynthetic enzymes are frequently clustered together. These BGCs are often regulated by a transcription factor encoded within the cluster itself. These pathway-specific regulators respond to a signal or indirectly through other means of environmental sensing. Many specialized metabolites are not produced under laboratory growth conditions, and one reason for this issue is that laboratory growth media lack environmental cues necessary for BGC expression. Here, we report a bioinformatics study that reveals that BGCs are frequently linked to genes coding for LuxR family QS-responsive transcription factors in the phylum Proteobacteria. The products of these luxR homolog-associated gene clusters may serve as a practical source of bioactive metabolites. PMID- 29600288 TI - Diffusion Tensor Cardiac Magnetic Resonance Reveals Exosomes From Cardiosphere Derived Cells Preserve Myocardial Fiber Architecture After Myocardial Infarction. AB - The object of the study was to reveal the fiber microstructural response with diffusion tensor cardiac magnetic resonance after intramyocardial exosomes secreted by cardiosphere-derived cells (CDCEXO) in chronic porcine myocardial infarction. Porcine with myocardial infarction underwent intramyocardial delivery of human CDCEXO and placebo in a randomized placebo-controlled study. Four weeks after injection, viability improved in the CDCEXO group, whereas myocardial fiber architecture and cardiac function were preserved. In the placebo group, fiber architecture and cardiac function declined. Myocardial regeneration by CDCEXO is not tumor-like; instead, details of tissue architecture are faithfully preserved, which may foster physiological excitation and contraction. PMID- 29600289 TI - Advancing research in regeneration and repair of the motor circuitry: non-human primate models and imaging scales as the missing links for successfully translating injectable therapeutics to the clinic. AB - Regeneration and repair is the ultimate goal of therapeutics in trauma of the central nervous system (CNS). Stroke and spinal cord injury (SCI) are two highly prevalent CNS disorders that remain incurable, despite numerous research studies and the clinical need for effective treatments. Neural engineering is a diverse biomedical field, that addresses these diseases using new approaches. Research in the field involves principally rodent models and biologically active, biodegradable hydrogels. Promising results have been reported in preclinical studies of CNS repair, demonstrating the great potential for the development of new treatments for the brain, spinal cord and peripheral nerve injury. Several obstacles stand in the way of clinical translation of neuroregeneration research. There seems to be a key gap in the translation of research from rodent models to human applications, namely non-human primate models, which constitute a critical bridging step. Applying injectable therapeutics and multimodal neuroimaging in stroke lesions using experimental rhesus monkey models is an avenue that a few research groups have begun to embark on. Understanding and assessing the changes that the injured brain or spinal cord undergoes after an intervention with biodegradable hydrogels in non-human primates seem to represent critical preclinical research steps. Existing innovative models in non-human primates allow us to evaluate the potential of neural engineering and injectable hydrogels. The results of these preliminary studies will pave the way for translating this research into much needed clinical therapeutic approaches. Cutting edge imaging technology using Connectome scanners represents a tremendous advancement, enabling the in vivo, detailed, high-resolution evaluation of these therapeutic interventions in experimental animals. Most importantly, they also allow quantifiable and clinically meaningful correlations with humans, increasing the translatability of these innovations to the bedside. PMID- 29600290 TI - Reorientation of the Methyl Group in MAs(III) is the Rate-Limiting Step in the ArsM As(III) S-Adenosylmethionine Methyltransferase Reaction. AB - The most common biotransformation of trivalent inorganic arsenic (As(III)) is methylation to mono-, di-, and trimethylated species. Methylation is catalyzed by As(III) S-adenosylmethionine (SAM) methyltransferase (termed ArsM in microbes and AS3MT in animals). Methylarsenite (MAs(III)) is both the product of the first methylation step and the substrate of the second methylation step. When the rate of the overall methylation reaction was determined with As(III) as the substrate, the first methylation step was rapid, whereas the second methylation step was slow. In contrast, when MAs(III) was used as the substrate, the rate of methylation was as fast as the first methylation step when As(III) was used as the substrate. These results indicate that there is a slow conformational change between the first and second methylation steps. The structure of CmArsM from the thermophilic alga Cyanidioschyzon merolae sp. 5508 was determined with bound MAs(III) at 2.27 A resolution. The methyl group is facing the solvent, as would be expected when MAs(III) is bound as the substrate rather than facing the SAM binding site, as would be expected for MAs(III) as a product. We propose that the rate-limiting step in arsenic methylation is slow reorientation of the methyl group from the SAM-binding site to the solvent, which is linked to the conformation of the side chain of a conserved residue Tyr70. PMID- 29600291 TI - Multi-state models and missing covariate data: Expectation-Maximization algorithm for likelihood estimation. AB - Multi-state models have been widely used to analyze longitudinal event history data obtained in medical and epidemiological studies. The tools and methods developed recently in this area require completely observed data. However, missing data within variables of interest is very common in practice, and it has been an issue in applications. We propose a type of EM algorithm, which handles missingness within multiple binary covariates efficiently, for multi-state model applications. Simulation studies show that the EM algorithm performs well for both missing completely at random (MCAR) and missing at random (MAR) covariate data. We apply the method to a longitudinal aging and cognition study dataset, the Klamath Exceptional Aging Project (KEAP), whose data were collected at Oregon Health & Science University and integrated into the Statistical Models of Aging and Risk of Transition (SMART) database at the University of Kentucky. PMID- 29600292 TI - Patients With Antithyroid Antibodies Are Prone To Develop Destructive Thyroiditis by Nivolumab: A Prospective Study. AB - Context: Immune checkpoint inhibitors, including anti-programmed cell death-1 (PD 1) antibodies, have become promising treatments for a variety of advanced malignancies. However, these medicines can cause immune-related adverse events (irAEs), including endocrinopathies. Objective: This study examined the incidence of endocrine irAEs induced by nivolumab. Patients and Main Outcome Measured: Sixty-six patients treated with nivolumab at Nagoya University Hospital were prospectively evaluated for pituitary hormones, thyroid function, antithyroid antibodies (Abs), and glucose levels every 6 weeks after the initiation of nivolumab for 24 weeks. Results: Four out of 66 patients developed destructive thyroiditis, and three patients developed hypothyroidism requiring levothyroxine replacement. The prevalence of positive anti-thyroglobulin Abs (TgAbs) and/or anti-thyroid peroxidase Abs (TPOAbs) at baseline was significantly higher in the group that developed destructive thyroiditis (3/4) compared with the group that did not develop thyroiditis (3/62; P = 0.002). There were no significant differences in other clinical variables between the groups. There were no endocrine irAEs other than destructive thyroiditis during the 24 weeks. The prevalence of TgAbs and/or TPOAbs at baseline was not associated with the development of other irAEs, including pneumonitis, colitis, or skin reactions. Conclusions: Our real-world data showed that destructive thyroiditis was an endocrine irAE that was frequently induced by nivolumab and was significantly associated with positive TgAbs and/or TPOAbs before treatment. Our findings indicate that evaluating these Abs before treatment may help identify patients with a high risk of thyroidal irAEs and may have important clinical benefit. PMID- 29600293 TI - USP8 Mutations in Pituitary Cushing Adenomas-Targeted Analysis by Next-Generation Sequencing. AB - Gain-of-function somatic mutations in the ubiquitin specific protease 8 (USP8) gene have recently been reported as a cause of pituitary adenomas in Cushing disease. Molecular diagnostic testing of tumor tissue may aid in the diagnosis of specimens obtained through therapeutic transsphenoidal surgery; however, for small tumors, availability of fresh tissue is limited, and contamination with normal tissue is frequent. We performed molecular testing of DNA isolated from single formalin-fixed and paraffin-embedded (FFPE) tissue sections of 42 pituitary adenomas from patients with Cushing disease (27 female patients and 15 male patients; mean age at surgery, 42.5 years; mean tumor size, 12.2 mm). By Sanger sequencing, we identified previously reported USP8 missense mutations in six tumors. Targeted next-generation sequencing (NGS) revealed known or previously undescribed missense mutations in three additional tumors (two with two different mutations each), with mutant allele frequencies as low as 3%. Of the nine tumors with USP8 mutations (mutation frequency, 21.4%), seven were from female patients (mutation frequency, 25.9%), and two were from male patients (mutation frequency, 13.3%). Mutant tumors were on average 11.4 mm in size, and patients with mutations were on average 43.9 years of age. The overall USP8 mutation frequency in our cohort was lower than in previously described cohorts, and we did not observe USP8 deletions that were frequent in other cohorts. We demonstrate that testing for USP8 variants can be performed from small amounts of FFPE tissue. NGS showed higher sensitivity for USP8 mutation detection than did Sanger sequencing. Assessment for USP8 mutations may complement histopathological diagnosis. PMID- 29600294 TI - Characteristics of Glucose Metabolism in Underweight Japanese Women. AB - Context: Japanese women have substantially lower body mass index (BMI) than women in other developed countries. The BMI of Japanese women has steadily decreased over time. However, glucose metabolism in underweight Japanese women has not been fully characterized. Objective: The aim of this study was to investigate glucose metabolism and the physical characteristics of underweight Japanese women. Design and Participants: We recruited 31 young (20 to 29 years of age) and 30 postmenopausal (50 to 65 years of age) underweight women. We also recruited young normal-weight women (n = 13) and postmenopausal normal-weight women (n = 10) to serve as references. We administered an oral glucose tolerance test (OGTT) and evaluated intramyocellular lipid (IMCL) levels and body composition using 1H magnetic resonance spectroscopy and dual-energy X-ray absorptiometry, respectively. Results: Young underweight women had similar glucose tolerance as young normal-weight women. However, postmenopausal underweight women had a higher area under the curve (AUC) for glucose during OGTT than postmenopausal normal weight women. In postmenopausal underweight women, 2-hour glucose levels during OGTT were negatively correlated with lean body mass (r = -0.55, P < 0.01) and insulinogenic index (r = -0.42, P = 0.02) and were positively correlated with IMCL levels (r = 0.40, P = 0.03). Compared with young underweight women, postmenopausal underweight women had a higher AUC for glucose during OGTT and a lower insulinogenic index and AUC for insulin during OGTT. Conclusions: Postmenopausal underweight women had more impaired glucose tolerance than young underweight women. In postmenopausal underweight women, the degree of glucose tolerance impairment was associated with decreased lean body mass, increased IMCL accumulation, and impaired insulin secretion.

PMID- 29600296 TI - Assessing the Effects of Software Platforms on Volumetric Segmentation of Glioblastoma. AB - Background: Radiological assessments of biologically relevant regions in glioblastoma have been associated with genotypic characteristics, implying a potential role in personalized medicine. Here, we assess the reproducibility and association with survival of two volumetric segmentation platforms and explore how methodology could impact subsequent interpretation and analysis. Methods: Post-contrast T1- and T2-weighted FLAIR MR images of 67 TCGA patients were segmented into five distinct compartments (necrosis, contrast-enhancement, FLAIR, post contrast abnormal, and total abnormal tumor volumes) by two quantitative image segmentation platforms - 3D Slicer and a method based on Velocity AI and FSL. We investigated the internal consistency of each platform by correlation statistics, association with survival, and concordance with consensus neuroradiologist ratings using ordinal logistic regression. Results: We found high correlations between the two platforms for FLAIR, post contrast abnormal, and total abnormal tumor volumes (spearman's r(67) = 0.952, 0.959, and 0.969 respectively). Only modest agreement was observed for necrosis and contrast enhancement volumes (r(67) = 0.693 and 0.773 respectively), likely arising from differences in manual and automated segmentation methods of these regions by 3D Slicer and Velocity AI/FSL, respectively. Survival analysis based on AUC revealed significant predictive power of both platforms for the following volumes: contrast-enhancement, post contrast abnormal, and total abnormal tumor volumes. Finally, ordinal logistic regression demonstrated correspondence to manual ratings for several features. Conclusion: Tumor volume measurements from both volumetric platforms produced highly concordant and reproducible estimates across platforms for general features. As automated or semi-automated volumetric measurements replace manual linear or area measurements, it will become increasingly important to keep in mind that measurement differences between segmentation platforms for more detailed features could influence downstream survival or radio genomic analyses. PMID- 29600302 TI - Prevalence of Orofacial Changes in Wind Instrumentalists: A Cross-Sectional Pilot Study in Brazil. AB - OBJECTIVE: The aim of the present study was to identify the prevalence of orofacial changes and factors associated with the frequent playing of wind instruments by musicians in Diamantina, Minas Gerais, Brazil. METHODS: A cross sectional study was conducted with 40 professional musicians who played wind instruments. The musicians filled out questionnaires about their habits and musical career. The Research Diagnostic Criteria were applied to investigate temporomandibular disorders. Other oral parameters examined included periodontal status, plaque index, and decayed, missing, and filled teeth (DMF) index. A significance level of p<0.05 was adopted for statistical analysis. RESULTS: The population included 22 (55%) men and 18 (45%) women, with a mean age of 25.88 yrs. The most common instruments played were the saxophone (n=12, 30%), clarinet (n=9, 22.5%), and flute (n=6, 15%). The most frequent pain complaint after playing was numbness in the upper lip or no sensation (25% of musicians), and the most frequent dental change observed was inclination of the upper teeth (15% of musicians). There was no significant association between dental changes, pain, and classification of instrument type. CONCLUSION: The main oral change that affected musicians who played wind instruments was the inclination of anterior teeth. PMID- 29600303 TI - Impact of Changes in Playing Time on Playing-Related Musculoskeletal Pain in String Music Students. AB - BACKGROUND: During their training, musicians must develop good work habits that they will carry on throughout their professional career in order to avoid potential chronic health problems, such as musculoskeletal pain. The effect of sudden changes in instrument playing-time on the development of playing-related musculoskeletal pain (PRMP) has not been thoroughly investigated in music students playing bowed string instruments (BSI), even though they are regularly exposed to such changes to perfect their playing skills. OBJECTIVE: To explore the association between sudden changes in instrument playing-time and changes in PRMP in BSI players. METHODS: A prospective cohort study was completed with BSI students attending a summer music camp offering high-level training. Participants completed a self-administered 23-item questionnaire designed for the study upon arrival at camp (T1) and then 7 days later (T2). RESULTS: Ninety-three BSI students (16+/-4 yrs old) completed the questionnaires, for a 23% response rate. Their playing-time increased by 23+/-14 hrs between T1 and T2. Complaints in pain frequency (e.g., from never to most of the time) and intensity (19+/-24 mm on VAS) significantly increased between T1 and T2 and were correlated with an increase in playing-time. CONCLUSION: A sudden increase in playing-time, such as that experienced by elite BSI students attending an intensive music camp, was related to an increase in PRMP. However, in this study, changes in pain characteristics were only partly explained by the change in playing-time. PMID- 29600304 TI - Health-Related Quality of Life in University Dance Students. AB - Injuries are common among dancers and may negatively affect health-related quality of life (HRQL). The modified Disablement in the Physically Active Scale (mDPA) is a generic patient-reported outcome instrument that could be used when providing care to patients participating in performing arts. The objective of this pilot study was to examine the internal consistency of the mDPA and assess overall HRQL using the mDPA in university dance students. Thirty-one female university dance students completed the mDPA during one data collection session. Higher scores on the Physical Summary Component (mDPA-PSC), the Mental Summary Component (mDPAMSC), and mDPA-Total indicated increased disablement. The internal consistency was determined using Cronbachs alpha. The mDPA-Total, mDPA-PSC, and mDPAMSC scores were examined descriptively using mean and standard deviations. Individual item responses were also examined. The proportion of university dance students with clinically relevant levels of disablement on the mDPA-Total was examined using a previously established minimally clinically important difference value. The internal consistency for the mDPA-MSC (a=0.91) and mDPATotal (a=0.90) was excellent and good for the mDPA-PSC (a=0.88). A large proportion (71%) of university dance students demonstrated clinically relevant levels of disablement despite fully participating in dance-related activities. Pain, impaired motion, and stress were the greatest contributors to increased disablement in these individuals. The mDPA scores observed in this pilot study indicate that many dance students experience levels of disablement and decreased HRQL which may warrant physical and mental intervention. Clinicians providing healthcare services to performing artists should consider using the mDPA to provide patient centered care. PMID- 29600305 TI - Comparison of Lower Extremity Muscle Flexibility in Amateur and Trained Bharatanatyam Dancers and Nondancers. AB - OBJECTIVE: This study compared lower limb muscle flexibility between amateur and trained female Bharatanatyam dancers and nondancers. METHODS: Subjects consisted of 105 healthy female volunteers, with 70 female Bharatanatyam dancers (35 trained, 35 amateurs) and 35 controls, with a mean (+/-SD) age of 16.2+/-1.04 yrs, height 155.05+/-4.30 cm, and weight 54.54+/-2.77 kg. Participants were assessed for range of motion (ROM) in hip flexion, hip extension, hip abduction and adduction, hip external rotation, hip internal rotation, knee flexion, knee extension, ankle dorsiflexion (DF), and ankle plantar flexion (PF) by using a standardized goniometer. To assess for significant difference between groups, one way ANOVA was applied, and multiple comparisons were made using Bonferroni correction. RESULTS: Trained dancers had a significantly greater hip flexion, extension, abduction, and external rotation ROM than amateurs and nondancers (p<0.05). Also, internal rotation and adduction were markedly less in trained dancers (p<0.05). Knee flexion, extension, and ankle DF were higher and ankle PF ROM was lesser in trained dancers. However, not much variation was found in ankle DF and PF between amateur dancers and nondancers (p>0.05). CONCLUSION: Results showed that there are significant differences in lower limb muscle flexibility between trained and amateur Bharatanatyam dancers and nondancers. These differences may be due to individual dance postures such as araimandi and muzhumandi. PMID- 29600306 TI - Epidemiology, Treatment Efficacy, and Anxiety Aspects of Music Students Affected by Playing-Related Pain: A Retrospective Evaluation with Follow-up. AB - OBJECTIVES: Playing-related pain (PRP) is a common problem among music students. We retrospectively assessed epidemiological factors that contributed to the manifestation of PRP and evaluated the efficacy of treatment methods used by affected music students. The long-term course of PRP symptoms was also examined, along with current (today) levels of trait anxieties. METHODS: Demographic and epidemiological data of 186 music students who visited the musicians' outpatient clinic over a 5-year period were retrieved. Of these students, 122 had been diagnosed with PRP and were invited to participate (response rate 61.5%) in a follow-up online survey to: a) estimate the long-term course of their PRP symptoms, b) assess the efficacy of treatment methods they used, and c) assess their current trait anxiety (general and performance-related) using two standardized psychodiagnostic questionnaires. RESULTS: Two-thirds of music students who sought medical care were affected by PRP, with most being affected during their first year of studies, and with 69% having acute rather than chronic pain. The sudden increase in practice time was the main triggering factor for PRP (but not for non-PRP-related problems). Concerning the course of PRP, almost all students recovered or improved significantly. Students reported that "active" treatment methods (e.g., physical activities) were more effective than "passive" methods (e.g., oral medications). Psychodiagnostic questionnaires indicated that about 40% of PRP-affected students currently had increased levels of trait anxieties (music and non-music related), possibly warranting further medical assistance. CONCLUSIONS: PRP in music students occurs mainly at the beginning of their studies and has a good prognosis, although recovery may be lengthy. It is necessary to provide students with early information about PRP and about the multidimensional treatment framework that allows for individualized care of PRP in affected music students. PMID- 29600307 TI - Effects of Aging on Musical Performance in Professional Orchestral Musicians. AB - BACKGROUND: The physical and psychological demands of playing a musical instrument are likely to be affected by age-related decline in function, including physical, cognitive, psychological, and organ-related changes. However, the complex neurophysiological demands of playing a musical instrument may delay many normal aging-related changes. AIM: This study compared professional classical musicians of different ages, using a range of physical and psychological measures, to discover how increasing age might affect work performance and to identify possible risk and protective factors for physical and psychological health as the musicians age. SUBJECTS: 377 professional orchestral musicians from eight Australian orchestras (70% response rate), ages 18 to 68 yrs (mean 42.1). Multiple standardized physical and psychological tools were used to evaluate the impact of age on a range of physical and mental health variables. RESULTS: Age was not statistically associated with frequency or severity of performance-related musculoskeletal disorders, ratings of perceived exertion, QuickDASH scores, use of beta-blockers, workplace satisfaction, and most psychological tests. Differences were observed on SPIN (social anxiety) scores, with lowest scores in the oldest age group (10.66 in 55+ yrs vs 17.83 in 18-30 yrs, p=0.016). Older musicians had higher BMIs and fewer practice sessions per day than younger musicians and also were more likely to consume alcohol on 5+ days/wk (44% vs 9%, p=0.003). CONCLUSION: Advancing age does not appear to exert undue negative impacts on physical and psychological health or performance capacity of professional orchestral musicians. However, dwindling numbers in the older age groups may suggest a "survivor" effect, whereby those who develop significant age-related decrements may cease professional performance at earlier ages. Longitudinal studies on the professional trajectories of professional orchestral musicians are needed to explore this question further. PMID- 29600308 TI - Extent of Playing-Related Musculoskeletal Problems in the Irish Traditional Music Community: A Survey. AB - BACKGROUND: The literature related to playing-related musculoskeletal disorders (PRMDs) primarily includes classical musicians and instrument-specific studies. Previous work by our team identified that PRMDs are an issue for Irish traditional fiddle players; however, the extent of the problem was not known. OBJECTIVE: To identify the type and extent of PRMDs in the Irish traditional music population, specifically fiddle players. METHODS: A questionnaire was developed and administered to faculty and students related to all Irish traditional music courses in all higher education institutions in Ireland. RESULTS: Seven institutions were included. The response rate was 77.5% (n=79 of 102 possible respondents). A fifth of respondents never had a PRMD, 36.7% (n=29) currently had a PRMD, and 34.2% (n=27) had a previous experience of a PRMD. The main symptoms were pain (62%, n=49), stiffness (41.8%, n=33), and tingling (35.4%, n=28). There was a positive association between the development of PRMDs and increased hours of play (p=0.017). CONCLUSIONS: PRMDs are a problem for Irish traditional fiddle players, especially during times of intense playing such as festivals. PMID- 29600309 TI - Musculoskeletal Assessments Used in Quantitatively Based Studies About Posture and Movement in High String Players: A Systematic Review. AB - OBJECTIVE: The aim of the study was to identify and systematically categorize musculoskeletal assessments used in quantitatively based studies about posture and movement in musicians playing high string instruments (violin, viola) in order to inform further research and help to identify gaps in knowledge. METHODS: A systematic literature search was conducted in the databases Cochrane, CINAHL, and PubMed as well as the journal Medical Problems of Performing Artists. Additional studies were searched within the reference lists of relevant articles. Sixty-four studies conducted since 1999 until May 2017 were included according to predefined inclusion criteria. RESULTS: Various biomechanical measurement instruments were used in 24 of the selected studies in order to collect two- and three-dimensional kinematic data: optoelectronic systems with active and passive markers, electromagnetic systems, ultrasonic motion analysis systems, and image based analysis of posture. In 11 studies, kinetics were measured by optoelectronic systems, force sensors, and a posturographic device. Further studies used electromyography to evaluate muscle activity (19 studies) as well as instruments to measure range of motion (2 studies). Additionally, a broad range of clinical examination techniques (35 studies) and self-reports (36 studies) were used to assess the musculoskeletal system of high string players. CONCLUSION: The identified assessments could be used both in further research and in practical work in order to evaluate posture and movement in high string players. For future research, qualitatively based studies as well as psychometrically tested quantitatively based self-report assessments are required. PMID- 29600310 TI - Pain Across Artists' Lifespan. AB - Having a lifelong career as a professional performing artist carries both challenges and benefits across different body systems. Pushing one's body to the limits results in a higher risk of suffering from some kind of episode of overload, whether it be physical or psychological. Indeed, a sudden increase in playing load (overtraining) is linked with increased frequency and intensity of pain or performance-related musculoskeletal disorders in both dance and music student populations. In this issue, research highlights this across the lifespan and in different genres of performing arts, including Irish fiddlers. PMID- 29600311 TI - Comparison of the diagnostic values of vascular adhesion protein-1 and intestinal fatty acid-binding protein in the diagnosis of acute mesenteric ischemia. AB - OBJECTIVES: The aim of this study is to compare the diagnostic values of plasma levels of vascular adhesion protein-1 (VAP-1) and intestinal fatty acid-binding protein (I-FABP) for diagnosing acute mesenteric ischemia (AMI). METHODS: The study used a randomized, controlled experimental design. Forty-two female Sprague Dawley rats were divided into three control groups and three ischemia groups. Plasma VAP-1 and I-FABP levels were measured, and the extent of ischemic damage was determined using a histopathological damage score in terminal ileum tissue samples. RESULTS: In the early phase of AMI (i.e. at the 30-min time point), VAP 1 levels did not differ between the control and ischemia groups (p > 0.05), but I FABP levels were significantly higher in the ischaemia groups (p = 0.017). Although both VAP-1 and I-FABP levels increased in the ischaemia groups, only VAP 1 levels showed a significant increase compared to the control group at the 2-h time point (p = 0.011). Ischemic damages associated with AMI became the most prominent at the 6-h time point. During this phase, both VAP-1 and I-FABP levels were significantly higher in the ischemia groups than in the control groups (p = 0.007 and p = 0.002, respectively). Both VAP-1 and I-FABP levels showed a significant correlation with ischemic changes, but a higher correlation was observed for VAP-1 levels (r = 0.771). CONCLUSIONS: Both I-FABP and VAP-1 levels were useful for diagnosing AMI, but VAP-1 levels correlated better with the extent of ischaemic damage.

AB - Conversion of agro-industrial wastes to energy is an innovative approach for waste valorization and management which also mitigates environmental pollution. In this view, present study investigated the feasibility of producing bioethanol from banana peels using cocktail of depolymerizing enzyme/s. We isolated Geobacillus stearothermophilus HPA19 from natural resource which produces cocktail of thermo-alkali-stable xylano-pectino-cellulolytic enzyme/s using wheat bran within 24 h. The optimal temperature and pH for xylanase, filter paper cellulase and pectinase were 80, 70 and 80 degrees C, and 9.0, 8.0 and 9.0, respectively. Cocktail enzymes showed stability at high temperature (80 degrees C) and pH (10.0). Ni2+ and Zn2+ promoted the relative activity of xylanase and FPase, whereas Na+, Ca2+ and K+ promoted pectinase activity. Cocktail was assessed in saccharification of banana peel. Reducing sugar obtained (37.06 mg ml 1) after one variable at a time (OVAT) method is greatly influenced by enzyme dose. Further, response surface methodology was used to optimize saccharification leading to twofold increase in reducing sugar. Maximum ethanol production (21.1 gl-1) was achieved through fermentation giving the efficiency of 76.5% within 30 h. Hence utilization of waste biomass for production of value-added products through biotechnological intervention not only helps to combat environmental pollution but also contributes significantly to the economy. PMID- 29600313 TI - Comparison of 1p and 19q status of glioblastoma by whole exome sequencing, array comparative genomic hybridization, and fluorescence in situ hybridization. AB - According to the 2016 World Health Organization classification of tumors of the central nervous system, detecting 1p/19q co-deletion became essential in clinical neuropathology for gliomas with oligodendroglioma-like morphology. Here, we assessed genomic profiles of glioblastoma in 80 cases including 1p/19q status using fluorescent in situ hybridization (FISH), array-comparative genomic hybridization (aCGH), and/or whole exome sequencing (WES). Paraffin-embedded tumor tissues were subjected to FISH analysis, and the corresponding frozen tissues from the same tumors were evaluated for aCGH and/or WES for 1p/19q co deletion and other genetic parameters, which included IDH1-R132H, ATRX, TP53, CIC, and NOTCH1 mutations and MGMT methylation status. We also evaluated correlations between 1p/19q co-deletion status and molecular markers or clinical outcomes. The FISH analyses revealed 1p/19q co-deletion in two cases, isolated deletion of 1p in six cases, and 19q in two cases, whereas the aCGH and WES results showed isolated deletion of 19q in four cases and 19 monosomy in only one case. Eleven cases showed discordant 1p/19q results between aCGH/WES and FISH analysis, and in most of them, 1p and/or 19q deletion on FISH analysis corresponded to the partial deletions at 1p36 and/or 19q13 on aCGH/WES. Our cohort exhibited IDH1-R132H mutations (5.4%), MGMT promotor methylation (34.6%), and mutations in ATRX (9.5%), TP53 (33.3%), and NOTCH1 (3.8%) but not in CIC (0%). In addition, MGMT methylation and ATRX mutation were significantly associated with clinical prognosis. In glioblastomas, partial deletions of 1p36 and/or 19q13 were uncommon, some of which appeared as 1p and/or 19q deletions on FISH analysis. PMID- 29600314 TI - Leaf area and photosynthesis of newly emerged trifoliolate leaves are regulated by mature leaves in soybean. AB - Leaf anatomy and the stomatal development of developing leaves of plants have been shown to be regulated by the same light environment as that of mature leaves, but no report has yet been written on whether such a long-distance signal from mature leaves regulates the total leaf area of newly emerged leaves. To explore this question, we created an investigation in which we collected data on the leaf area, leaf mass per area (LMA), leaf anatomy, cell size, cell number, gas exchange and soluble sugar content of leaves from three soybean varieties grown under full sunlight (NS), shaded mature leaves (MS) or whole plants grown in shade (WS). Our results show that MS or WS cause a marked decline both in leaf area and LMA in newly developing leaves. Leaf anatomy also showed characteristics of shade leaves with decreased leaf thickness, palisade tissue thickness, sponge tissue thickness, cell size and cell numbers. In addition, in the MS and WS treatments, newly developed leaves exhibited lower net photosynthetic rate (Pn), stomatal conductance (Gs) and transpiration rate (E), but higher carbon dioxide (CO 2 ) concentration in the intercellular space (Ci) than plants grown in full sunlight. Moreover, soluble sugar content was significantly decreased in newly developed leaves in MS and WS treatments. These results clearly indicate that (1) leaf area, leaf anatomical structure, and photosynthetic function of newly developing leaves are regulated by a systemic irradiance signal from mature leaves; (2) decreased cell size and cell number are the major cause of smaller and thinner leaves in shade; and (3) sugars could possibly act as candidate signal substances to regulate leaf area systemically. PMID- 29600315 TI - Integrated taxonomy of the Asplenium normale complex (Aspleniaceae) in China and adjacent areas. AB - The Asplenium normale D. Don complex comprises several taxa that are either diploid or tetraploid. The tetraploids are assumed to have originated from diploid ancestors by relatively recent autopolyploidization or allopolyploidization. Some of the diploids are readily recognized morphologically but most of the taxa have until now been placed into a single species. However, phylogenetic studies have challenged this treatment and emphasized the notion that the taxonomic treatment of this complex needs to be revised. An integrative taxonomic approach was employed to delimit species in the complex using cytological, morphological, and DNA sequence data. Initially, we employed a diploid first approach to establish a robust taxonomic framework. Special efforts were made to collect and identify the diploid progenitors of each polyploid lineage identified in the plastid DNA based phylogenetic hypothesis. A total of six distinct diploid species were identified. The distinctive nature of the six diploids is strongly supported by sequence differences in plastid DNA and nuclear loci, as well as by the results of morphometric analysis. Diagnostic morphological characters were identified to distinguish the six diploid species, resulting in their revised taxonomy, which includes two novel species, namely, Asplenium normaloides and A. guangdongense. Further studies to strengthen the taxonomic classification of all of the tetraploid taxa are warranted. PMID- 29600316 TI - Optimization of a Bioluminescence Resonance Energy Transfer-Based Assay for Screening of Trypanosoma cruzi Protein/Protein Interaction Inhibitors. AB - Chagas disease, a parasitic disease caused by Trypanosoma cruzi, is a major public health burden in poor rural populations of Central and South America and a serious emerging threat outside the endemic region, since the number of infections in non-endemic countries continues to rise. In order to develop more efficient anti-trypanosomal treatments to replace the outdated therapies, new molecular targets need to be explored and new drugs discovered. Trypanosoma cruzi has distinctive structural and functional characteristics with respect to the human host. These exclusive features could emerge as interesting drug targets. In this work, essential and differential protein-protein interactions for the parasite, including the ribosomal P proteins and proteins involved in mRNA processing, were evaluated in a bioluminescence resonance energy transfer-based assay as a starting point for drug screening. Suitable conditions to consider using this simple and robust methodology to screening compounds and natural extracts able to inhibit protein-protein interactions were set in living cells and lysates. PMID- 29600317 TI - Septal branches of the anterior ethmoidal artery: anatomical considerations and clinical implications in the management of refractory epistaxis. AB - PURPOSE: Epistaxis is a commonly presenting complaint. In severe cases, nosebleeds may occur despite antero-posterior nasal packing and often in the absence of identifiable sources of bleeding. In such cases, epistaxis may occur from septal branches of the anterior ethmoidal artery (sbAEA). The purposes of this study are to highlight the clinical role of the sbAEA in different fields of endoscopic endonasal surgery and to evaluate the efficacy and safety of their selective endoscopic endonasal ligation in the management of refractory epistaxis. METHODS: A retrospective review was performed of all patients presenting with epistaxis who underwent endoscopic endonasal coagulation of sbAEA in three Italian tertiary-care referral centers between October 2010 and October 2017. RESULTS: A total of 30 patients met the inclusion criteria. Sixteen patients had never experienced nosebleeds before, while 14 patients recalled previous epistaxes. Seventeen patients were treated under local anesthetic, while 13 required general anesthesia. No intra- or post-operative complications were observed and none of the patients received nasal packing after the procedure. In all cases the coagulation was effective in controlling the bleeding, with only two relapses in the series (2/30, 6.7%). CONCLUSIONS: The sbAEA are of great interest in endoscopic endonasal surgery, both as surgical landmarks and as feeding vessels for a variety of pedicled nasal flaps. What is more, they can be crucial for the management of refractory epistaxis. Their selective endoscopic coagulation represents an effective and safe procedure in cases of difficult-to control epistaxis from the upper nasal fossa, with several advantages over nasal packing. PMID- 29600318 TI - Do turbinate reduction procedures restore epithelial integrity in patients with turbinate hypertrophy secondary to allergic rhinitis? A histopathological study. AB - PURPOSE: Consensus has not been reached regarding the optimal reduction procedure for inferior turbinate hypertrophy in allergic rhinitis and whether such procedures result in improvement in mucosal architecture. METHODS: Twenty-nine patients aged 18-45 years (mean 26.8 years), with allergic rhinitis and inferior turbinate hypertrophy not responsive to medical therapy who underwent endoscopic submucosal diathermy (ESMD) (14 patients) or endoscopic submucosal resection (ESMR) (15 patients) with intraoperative and 3-6 months postoperative inferior turbinate biopsies, were included in the study. Epithelial and mucosal architecture was compared between the two groups. RESULTS: Both groups showed a significant decrease in epithelial denudation (p < 0.001), reversal of basement membrane thickening (p < 0.001) and increase in density of cilia (p < 0.001). The degree of improvement in histological characteristics between ESMD and ESMR groups was not significant. CONCLUSIONS: Surgical intervention for inferior turbinate hypertrophy by both ESMD and ESMR results in significant restoration of nasal mucosal epithelium in patients with allergic rhinitis as early as 3-month postoperatively. There was, however, no significant difference in the histological changes between those who underwent ESMD and ESMR. CLINICAL TRIALS OF INDIA, REGISTRY NUMBER: CTRI/2015/01/005373. PMID- 29600319 TI - Patients with unilateral squamous cell carcinoma of the tongue and ipsilateral lymph node metastasis do not profit from bilateral neck dissection. AB - OBJECTIVES: The purpose of this study was to evaluate the necessity of elective bilateral neck dissection for treating strict unilateral squamous cell carcinoma (SCC) of the tongue. METHODS: A cohort of 169 patients with unilateral non midline crossing SCCs of the tongue treated by local resection and neck dissection was investigated. Study endpoints were nodal relapse and overall survival. The mean follow-up was 7.4 years. RESULTS: A total of 146 (88.1%) patients were treated by neck dissection. Lymph node metastases were diagnosed in 50 (34.2%) patients. Only two (1.1%) had contralateral lymph node metastases. Risk factors for developing a primary lymph node metastasis were size of tumor (T2/T3, p = 0.03; OR = 2.2), lymphangiosis (p = 0.003; OR = 4.7), and higher grade differentiation (p = 0.051; OR = 2.43). Metachronous lymph node metastases were detected in 23 (13.6%) patients (19 ipsilateral, one contralateral and three bilateral). The main risk factor for developing a metachronous lymph node metastasis was the presence of a primary lymph node metastasis (p = 0.004; HR = 4.65). Patients with initial neck dissection came up with lower 5-year recurrence rates (13.6%) compared to patients without neck dissection (27.3%; p = 0.014). Bilateral neck dissection showed no advantage regarding nodal relapse free and overall survival (p = 0.606) compared to unilateral neck dissection irrespective of initial N or T stage. CONCLUSION: Patients with unilateral SCC of the tongue benefit from an ipsilateral neck dissection regarding nodal relapse. The value of elective bilateral neck dissection as standard treatment seems questionable even if positive lymph nodes were diagnosed ipsilateral at primary therapy. PMID- 29600320 TI - Early results of total arch replacement under partial sternotomy. AB - OBJECTIVE: Partial sternotomy with limited skin incision has been utilized for cardiac surgery. We, therefore, started to apply the partial sternotomy for total arch replacement since 2013 in selected cases. The aim of this study reported the results of our early experiences. METHODS: Between July 2013 and December 2015, we retrospectively reviewed 15 cases (median age 72, range 67-84, 15 male) who underwent total arch replacement thorough partial sternotomy. All procedures were performed under hypothermic circulatory arrest with selective cerebral perfusion. RESULTS: Median skin incision was 9 cm (range 7-15 cm, 5.3% of height) and partial sternotomy consisted of 14 upper and 1 lower partial sternotomy (L shape 8 and T shape 7 cases). Median operation time, cardiopulmonary bypass time, ischemic heart time, selective cerebral perfusion time and hypothermic circulatory arrest time were 485 [360-770], 223 [1174-270], 146 [100-163], 154 [116-189], and 69 [45-90] minutes, respectively. Median duration of mechanical ventilator dependent time was 12 h [5-38]. Median length of ICU stay and hospital stay were 3 [1-7], and 18 [13-76] days, respectively. Thirty days and in-hospital mortality were 0% without any neurological complications. There are two aorta related reoperation due to graft inducing hemolytic anemia and no aorta-related death during follow-up (median 954, range 702-1462 days). CONCLUSION: The early results of total arch replacement through partial sternotomy were satisfactory. The partial sternotomy could be a good option for total arch replacement in selected patients. PMID- 29600321 TI - Can ebselen prevent cisplatin-induced ovarian damage? AB - PURPOSE: The occurrence of ovarian damage is a major shortcoming in treating tumors with cisplatin (CP). The present study investigates the beneficial effects of ebselen-a seleno-organic compound with antioxidant and antiinflammatory properties-vis-a-vis CP-induced ovarian damage. METHODS: Twenty-eight adult female rats were divided into four study groups. Group 1 received no treatment. The rats in Groups 2, 3, and 4 were intraperitoneally administered CP (2 mg/kg/day) twice per week, for 5 weeks. Those in Group 2 received 0.3 ml saline (0.9% NaCl) intraperitoneally 60 min before each CP treatment, while those in Group 3 received 0.2 ml dimethyl sulfoxide (DMSO) and 0.3 ml saline intraperitoneally 60 min before each CP treatment. The rats in Group 4 were pretreated with an intraperitoneal injection of 15 mg/kg/day ebselen 60 min before each CP treatment. Ovarian tissue malondialdehyde (MDA), total nitric oxide (NOx), glutathione (GSH), Cu/Zn-superoxide dismutase (Cu/Zn-SOD), and catalase levels, as well as histopathological damage scores (HDSs) and serum antimullerian hormone (AMH) levels, were assessed. RESULTS: Cu/Zn-SOD and GSH levels were significantly higher, and MDA and NOx levels significantly lower, in Group 4 than in Groups 2 and 3. Pretreatment with ebselen significantly improved serum AMH levels, relative to Groups 2 and 3. Additionally, HDS values were significantly lower in Group 4 than in Groups 2 and 3. CONCLUSIONS: Our results from using an experimental rat model of CP chemotherapy suggest that ebselen use may ameliorate ovarian damage by preventing oxidative injury. PMID- 29600322 TI - Dual triggering with GnRH agonist plus hCG versus triggering with hCG alone for IVF/ICSI outcome in GnRH antagonist cycles: a systematic review and meta analysis. AB - PURPOSE: To summarize available evidence from randomized-controlled trials which have evaluated triggering of final oocyte maturation with concomitant GnRH agonists and hCG in patients undergoing IVF, and to analyze whether dual triggering is as efficacious as hCG triggering in terms of oocyte and pregnancy outcomes. METHODS: A comprehensive literature search was performed to identify randomized-controlled trials comparing IVF outcomes between women receiving combined administration of hCG with GnRH agonists and those receiving hCG alone for triggering of final oocyte maturation. RESULTS: Four studies including 527 patients eligible for inclusion in meta-analysis were identified. No significant difference in the number of mature oocytes or fertilized oocytes retrieved was found between groups. Clinical pregnancy rate with dual triggering was significantly higher as compared with hCG-alone triggering (pooled OR = 0.48, 95% CI 0.31-0.77, P = 0.002), but there was no significant difference in the ongoing pregnancy rate between groups. CONCLUSION: Results of meta-analysis indicate comparable or significantly improved outcomes with the use of GnRH agonists plus hCG as compared with hCG alone for triggering of final oocyte maturation. PMID- 29600323 TI - Assessment of polyurethane spheres as surrogates for military ballistic head injury. AB - SYNBONE(r) spheres were impacted with 7.62 * 39 mm mild steel core ammunition at a mean impact velocity of 654 m/s, SD 7 m/s, to simulate engagement distances of around 50-100 m. The wounds and fracture patterns were assessed by two forensic pathologists familiar with military cranial injury. The overall fracture pattern was assessed as being too comminuted when compared with actual injury. This suggests the SYNBONE(r) spheres have less utility for simulating military injury than other purposes described in the literature. PMID- 29600324 TI - A toolkit for the management of infection or colonization by extended-spectrum beta-lactamase producing Enterobacteriaceae in Italy: implementation and outcome of a European project. AB - Among European countries, prevalence rates of extended-spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) are particularly high in those bordering the Mediterranean. This is the case for Italy, with 26% of Escherichia coli displaying resistance to the 3rd generation cephalosporins in 2013. An ESBL-E toolkit designed to assist clinicians in managing patients harboring ESBL-E was favorably implemented in Southern France. In a context of lack of specific Italian recommendations, its extension to an adjacent region of Italy was made possible through a cross-border EU cooperation program. Italian infectious disease (ID) specialists, microbiologists, and community-based general practitioners from three districts in Liguria were offered a toolkit consisting in a warning system and detailed procedures for the management of patients harboring ESBL-E, including seeking advice from an ID specialist, and were trained during 52 video conferences by an experienced French team. Indications and trends in antimicrobial prescription were studied following implementation of the toolkit. Between November 2013 and November 2014, 476 patients were identified as harboring ESBL-E and expert advice was sought for 364 of these; all patients and/or their caregivers were advised on appropriate hygiene measures and 209/341 with documented management received antimicrobial treatment, while asymptomatic carriers (39%) were not prescribed antibiotics. The ESBL-E toolkit was well received by the healthcare staff. A specific, simple tool consisting in a care-bundle approach to manage ESBL-E carriers can restrict antimicrobial prescription to symptomatic patients while raising awareness among caregivers of the importance of seeking expert advice and implementing appropriate hygiene measures. PMID- 29600325 TI - Associations between biomarkers at discharge and co-morbidities and risk of readmission after community-acquired pneumonia: a retrospective cohort study. AB - To investigate whether hemoglobin, white blood cell count (WBC), urea, sodium, albumin, and C-reactive protein at discharge in patients hospitalized for community-acquired pneumonia (CAP) are associated with 30-day readmission. This study is a retrospective cohort study, which included all adult patients discharged after hospitalization for CAP from three Danish hospitals between January 2011 and July 2012. The outcome was all-cause, unplanned, 30-day readmission. Biomarker concentrations at discharge were transformed into binary variables by using either upper or lower quartiles as cut-off; the upper quartile was used for WBC, urea, and C-reactive protein, and the lower quartile was used for hemoglobin, sodium, and albumin. The study population consisted of 1149 patients. One hundred eighty-four (16.0%) patients were readmitted. Independent risk factors of readmission were WBC >= 10.6 cells * 109/L (hazard ratio 1.50; 95% CI, 1.07-2.11) and albumin <32 g/L (hazard ratio 1.78; 95% CI, 1.24-2.54) at discharge and the presence of >= 2 co-morbidities (hazard ratio 1.74; 95% CI, 1.15-2.64). When WBC, albumin, and co-morbidities were combined into a risk stratification tool, there was a step-wise increase in risk of readmission for patients with 1, 2, or 3 risk factors with hazard ratios of 1.76 (95% CI, 1.25 2.49), 2.59 (95% CI, 1.71-3.93), and 6.15 (95% CI 3.33-11.38), respectively. WBC >= 10.6 cells * 109/L and albumin < 32 g/L at discharge and the presence of >= 2 co-morbidities were independently associated with increased risk of 30-day readmission. PMID- 29600326 TI - Right trisegmentectomy after portal vein embolization in a high-risk toddler with hepatoblastoma. AB - Portal vein embolization (PVE) is a pre-operative treatment modality in adults undergoing hepatectomy with concerns of post-operative liver failure from insufficient future liver remnant (FLR). PVE induces growth in the FLR. The success of this technique is well described in adults, but not in young children with hepatoblastoma. PMID- 29600328 TI - Cross-sectional association of dietary water intakes and sources, and adiposity: National Adult Nutrition Survey, the Republic of Ireland. AB - PURPOSE: Drinking (plain) water intake has been associated with weight loss and reducing energy intake in intervention trials. In free-living populations, replacing other beverages with drinking water is associated with reduced obesity risk. However, the association of total water intake and its sources, and body fat distribution remain unevaluated. Thus, the aim of this study was to investigate total water intake and its sources and the association with anthropometric measures. METHODS: Cross-sectional study of 1500 adults aged 18-90 years (Irish National Adult Nutrition Survey, 2008-2010). Total water intake and its sources were estimated using food records. Associations of total water, drinking water, beverage moisture and food moisture intakes split by tertile, and BMI (kg/m2), waist circumference (cm), and bio-impedance derived body fat (%) were evaluated using covariate-adjusted linear regression analyses including adjustment for energy intake and energy expenditure. RESULTS: Higher consumption of total water was associated with lower waist circumference [beta-coefficient (95% CI), p trend, tertile 3 versus tertile 1: - 2.19 (- 4.06, - 0.32), 0.036], but not BMI [- 0.44 (- 1.16, 0.28), 0.336] or body fat [- 0.87 (- 1.91, 0.17), 0.146]. Higher consumption of drinking water and food moisture were associated with lower BMI [- 0.65 (- 1.30, - 0.01), 0.027; - 0.64 (- 1.41, - 0.13), 0.014, respectively], body fat [- 1.51 (- 2.43, - 0.59), 0.001; - 1.00 (- 2.12, - 0.12), 0.001], and waist circumference [- 2.83 (- 4.51, - 1.16), < 0.001; - 1.84 (- 3.86, - 0.19), 0.082]. Beverage moisture was not associated with any of the anthropometric measurements. CONCLUSIONS: Consumption of drinking water and food moisture and not total water or beverage moisture were inversely associated with adiposity, independent of energy intake and expenditure. Advice encouraging drinking water and food moisture intake may be beneficial in addition to energy balance advice, in combating obesity. PMID- 29600327 TI - The histamine H4 receptor modulates the differentiation process of human monocyte derived M1 macrophages and the release of CCL4/MIP-1beta from fully differentiated M1 macrophages. AB - OBJECTIVE: Histamine is an important mediator of biological functions and present in high amounts in inflammatory skin lesions which are characterised by a marked infiltration of myeloid derived cell populations. The aim of the study was to investigate the expression and function of histamine receptors, with a focus on the histamine H4 receptor (H4R) in detail during the differentiation process from monocytes to macrophages and on fully differentiated M1 macrophages. METHODS: Quantitative PCR, ELISA technique, and flow cytometry were applied to analyze expression levels of histamine receptors, of CXCL10, CCL4, CCL3, or IL-23 and of the macrophage differentiation marker CD68, respectively. RESULTS: We demonstrated that monocytes and fully differentiated M1 macrophages express H1R-, H2R-, and H4R mRNA which were differentially regulated during the differentiation process and in IFN-Y and LPS classically activated M1 macrophages. The H3R mRNA was not expressed. During in vitro differentiation from monocytes to macrophages, the H4R agonist ST-1006 modified the M1 phenotype by up-regulating the macrophage differentiation marker CD68, by down-regulating the production of CXCL10, and by changing the morphology. In fully differentiated M1 macrophages, histamine or ST 1006 decreased the IFN-Y- and LPS-induced CCL4 mRNA expression and protein production, whereas CCL3 or IL-23 production was not regulated via H4R. CONCLUSIONS: We describe novel immunomodulatory functions of the H4R during the differentiation process of human monocyte-derived macrophages and in fully differentiated M1 macrophages. The down-regulation of Th1-related chemokines during the differentiation process or in classically activated macrophages via H4R may contribute to decreased migration of immune cells to the site of inflammation. This may have implications for the treatment of allergic diseases with H4R ligands regulating the dysbalance of Th2/Th1 polarizations in these disorders. PMID- 29600329 TI - Dietary wheat amylase trypsin inhibitors exacerbate murine allergic airway inflammation. AB - BACKGROUND: Wheat amylase trypsin inhibitors (ATI) are dietary non-gluten proteins that activate the toll-like receptor 4 on myeloid cells, promoting intestinal inflammation. AIM OF THE STUDY: We investigated the effects of dietary ATI on experimental allergic airway inflammation. METHODS: Mice on a gluten and ATI-free diet (GAFD), sensitized with PBS or ovalbumin (OVA) and challenged with OVA, were compared to mice on a commercial standard chow, a gluten diet naturally containing ~ 0.75% of protein as ATI (G+AD), a gluten diet containing ~ 0.19% of protein as ATI (G-AD) and a GAFD with 1% of protein as ATI (AD). Airway hyperreactivity (AHR), inflammation in bronchoalveolar lavage (BAL) and pulmonary tissue sections were analyzed. Allergic sensitization was assessed ex vivo via proliferation of OVA-stimulated splenocytes. RESULTS: Mice on a GAFD sensitized with PBS did not develop AHR after local provocation with methacholine. Mice on a GAFD or on a G-AD and sensitized with OVA developed milder AHR compared to mice fed a G+AD or an AD. The increased AHR was paralleled by increased BAL eosinophils, IL-5 and IL-13 production, and an enhanced ex vivo splenocyte activation in the ATI-fed groups. CONCLUSIONS: Dietary ATI enhance allergic airway inflammation in OVA-challenged mice, while an ATI-free or ATI-reduced diet has a protective effect on AHR. Nutritional wheat ATI, activators of intestinal myeloid cells, may be clinically relevant adjuvants to allergic airway inflammation.

PMID- 29600331 TI - Influence of fascicle length on twitch potentiation of the medial gastrocnemius across three ankle angles. AB - PURPOSE: Length dependence of post-activation potentiation (PAP) is a well established phenomenon in animal models but less certain in intact whole human muscles. Recent advances in B-mode ultrasonography provide real-time imaging and evaluation of human muscle fascicles in vivo, thus removing the assumption that joint positioning alters fascicle length and influences the extent of PAP. The purpose of this study was to determine whether a conditioning maximal voluntary contraction (MVC) would influence the return of medial gastrocnemius (MG) fascicles to baseline length and alter the extent of twitch potentiation between three ankle positions. METHODS: Ultrasonography was used to measure MG fascicle length for baseline and potentiated twitches at angles of 10 degrees dorsiflexion (DF), 0 degrees neutral (NEU-tibia perpendicular to the sole of the foot), and 20 degrees plantar flexion (PF). A MVC was used as a conditioning contraction and PAP determined for each ankle angle. RESULTS: PAP of the plantar flexors was greater in PF (28.8 +/- 2.6%) compared to NEU (19.8 +/- 1.8%; p < 0.05) and DF (9.3 +/- 2.8%; p < 0.0001). In PF, fascicle lengths (4.64 +/- 0.17 cm) were shorter than both NEU (5.78 +/- 0.15 cm; p < 0.0001) and DF (6.09 +/- 0.15 cm; p < 0.0001). Fascicle lengths for the baseline twitches were longer (5.92 +/- 0.11 cm) than the potentiated twitches (5.83 +/- 0.10 cm; p < 0.01) at all joint angles. CONCLUSION: Although PAP is greatest in PF compared to NEU and DF, the higher PAP in the PF joint angle cannot be attributed to fascicles remaining shortened following the MVC because across all joint positions, fascicles are similarly shortened following the MVC. PMID- 29600330 TI - Measuring the Impact of Gastrointestinal Variables on the Systemic Outcome of Two Suspensions of Posaconazole by a PBPK Model. AB - For the last two decades, the application of physiologically based pharmacokinetic (PBPK) models has grown exponentially in the field of oral absorption and in a regulatory context. Although these models are widely used, their predictive power should be validated and optimized in order to rely on these models and to know exactly what is going on "under the hood". In this study, an automated sensitivity analysis (ASA) was performed for 11 gastrointestinal (GI) variables that are integrated into the PBPK software program Simcyp(r). The model of interest was a previously validated workspace that was able to predict the intraluminal and systemic behavior of two different suspensions of posaconazole in the Simcyp(r) Simulator. The sensitivity of the following GI parameters was evaluated in this model: gastric and duodenal pH, gastric and duodenal bicarbonate concentrations (reflecting buffer capacity), duodenal bile salts concentration, gastric emptying, the interdigestive migrating motor complex (IMMC), small intestinal transit time (SITT), gastric and jejunal volumes, and permeability. The most sensitive parameters were gastric/duodenal pH and gastric emptying, for both suspensions. The outcome of the sensitivity analyses highlights the important GI variables that must be integrated into an in vivo predictive dissolution test to help and create a rational and scientific framework/design for product development of novel and generic drug products. PMID- 29600333 TI - Predictors of surgical intervention following initial surveillance for acute ureteric colic. AB - PURPOSE: To identify clinical and stone-related factors predicting the need for surgical intervention in patients who were clinically considered appropriate for non-surgical intervention. PATIENTS AND METHODS: We conducted a retrospective review of a contemporary cohort of patients who were selected for surveillance following presentation with acute ureteric colic. Data on patient demographic and stone variables, inpatient management and long-term outcomes were evaluated. Multivariate logistic regression was used to generate a nomogram predicting need for surgical intervention. The accuracy of the nomogram was subsequently validated with an independent cohort of patients presenting with ureteric colic. RESULTS: Of 870 study eligible patients presenting with acute ureteric colic, 527 were initially treated non-surgically and included in the analysis. 113 of these eventually required surgical intervention. Median time from first presentation to acute surgery was 11 (IQR 4-82) days. In our final MVA analysis, duration of symptoms more than 3 days, not receiving alpha-blockers, positive history of previous renal calculi and stone location, burden and density were independent predictors of need for surgical intervention. Patients who required opioid analgesia were more likely to have surgical intervention; however, this did not reach statistical significance. The area under the curve (AUC) of the final model was 0.802. The nomogram was validated with a cohort of 210 consecutive colic patients with AUC of 0.833 (SE 0.041, p < 0.001). CONCLUSIONS: We have identified independent predictors of the need for surgical intervention during an episode of renal colic and formulated a nomogram. Combined with the diligent use of acute ureteroscopy at our centre, this nomogram may have clinical utility when making decisions regarding treatment options with potential healthcare cost savings. PMID- 29600334 TI - Supra-pubic versus urethral catheter after robot-assisted radical prostatectomy: systematic review of current evidence. AB - PURPOSE: To provide latest evidence on the use of suprapubic catheter (SPC) versus urethral catheter (UC) after robot-assisted laparoscopic radical prostatectomy (RARP). MATERIALS AND METHODS: A systematic revision of literature was performed up to September 2017 using different search engines (Pubmed, Ovid, Scopus) to identified studies comparing the use of SPC versus standard UC after RARP. Identification and selection of the studies were conducted according to the preferred reporting items for systematic reviews and meta-analysis criteria. For continuous outcomes, the weighted mean difference (WMD) was used as a summary measure, whereas the odds ratio (OR) or risk ratio (RR) with 95% confidence interval (CI) was calculated for binary variables. RR was preferred in cases of a high number of events to avoid overestimation. Pooled estimates were calculated using the random-effect model to account for clinical heterogeneity. All statistical analyses were performed using Review manager 5 (Cochrane Collaboration, Oxford, UK). RESULTS: Eight studies were identified and included in this systematic review, namely 3 RCTs, 4 non-randomized prospective studies, and one retrospective study. A total of 966 RARP cases were collected for the cumulative analysis. Among them, 492 patients received standard UC and 474 SPC placement after RARP. UC patients had higher baseline PSA (WMD 0.44 ng/ml; p = 0.02). Visual Analog Scale (VAS) score was found to be significantly lower in patients with SPC at postoperative day 7 (WMD 0.53; 95% CI 0.13-0.93; p = 0.009). Regarding penile pain, a significant difference in favor of the SPC group was found at postoperative day 7 assessment (WMD 1.2; 95% CI 0.82-1.6; p < 0.001). More patients in the SPC group reported "not at all" or "minimal pain" at this time point (OR 0.17, 95% CI 0.06, 0.44; p < 0.001). No significant differences were found in terms of continence recovery rate at 6-12 weeks between the groups (UC 78.7%, 88.2%; RR 0.92, 95% CI 0.84, 1.01; p = 0.09). Similarly, no differences were found in terms of catheter-related issues (p = 0.17). However, UC patients had lower likelihood of overall complications (OR 0.44, 95% CI 0.21 0.89, p = 0.02). CONCLUSIONS: Available evidence suggests that the use of SPC can be a viable option for postoperative urine drainage after RARP, as it can translate into decreased postoperative pain without carrying a significant higher risk of catheter-related complications. Further investigation seems to be warranted, ideally within the framework of a multicentre randomized study with standardized analysis of outcomes. PMID- 29600335 TI - Radiation exposure for intraoperative 3D scans in a hybrid operating room: how to reduce radiation exposure for the surgical team. AB - BACKGROUND: Hybrid operating rooms are used in different fields of surgery. In orthopedic surgery, the possibility of a 3D scan of difficult anatomical regions (spine, pelvis) showed promising results not only in navigated screw placement. The associated exposure to radiation raises questions regarding potential risks for the operating room personal and the patient. The present study focuses on scatter radiation during 3D scans in a hybrid operating room, the adjacent rooms, and methods to reduce radiation exposure. MATERIAL AND METHODS: [Formula: see text] i2 dosimeters were used to measure scatter radiation during 3D scans of different anatomical regions in different distances and heights in a hybrid operating room. The 3D scans were performed with a floor-based flat-panel robotic C-arm with 3D scan capability (Artis Zeego, Siemens; Germany). The 3D scans were performed using a human cadaver. The 3D scans were performed using a standard and a dose reduction protocol (DRP). RESULTS: The highest scatter radiation was measured during 3D scans of the pelvis on the side of the surgical assistant (39.5 uSv in height of 1 m) compared to the side of the main surgeon (23 uSv in height of 1 m). Scatter radiation was less on the position of the scrub nurse (6.8 uSv in height of 1 m) and during 3D scans of the other anatomical regions. The radiation dosage was about 66% less with the DRP. Low values of scatter radiation were measured behind a radiation protection wall and with open doors in the adjacent rooms. CONCLUSION: While performing a scan scatter radiation was measured everywhere in the operating room especially during 3D scans of the pelvic girdle. Therefore, settings with lower dosage should be used whenever possible. Personnel should stand behind a radiation safety wall or leave the operating room and close the doors. For this study, six behavioral rules to avoid radiation in a hybrid operating room were established. PMID- 29600336 TI - [Atrial fibrillation as a comorbidity of heart failure]. AB - Atrial fibrillation and heart failure are diseases that frequently occur together in patients, and the prevalence of the two diseases will continue to increase in the future. Unfortunately, they exacerbate each other: the prognosis of patients with atrial fibrillation is poorer if there is heart failure, and the prognosis of heart failure patients with atrial fibrillation is poorer than the prognosis of heart failure patients without atrial fibrillation. In the past, studies on drug stabilization of sinus rhythm with antiarrhythmic drugs were not able to show any influence on the prognosis of patients. In these patients, it seems to be better to treat the atrial fibrillation interventionally. The CASTLE-AF study has just shown for the first time that isolation of the pulmonary vein to treat atrial fibrillation in heart failure patients has positive effects: hospital admissions for heart failure decreased and the overall survival improved. Further studies have shown that quality of life improves and performance is increased. PMID- 29600337 TI - Mutations in Smad-interacting protein 1 gene are responsible for absence of its expression in Hirschsprung's disease. AB - Hirschsprung's disease (HSCR) is a common congenital malformation of the enteric nervous system. The pathophysiological basis remains unclear. Recently, the SIP1 gene has been recognized as being involved in the pathogenesis of symptomatic HSCR patients with 2q22 chromosomal rearrangement. In this study, mutations in SIP1 were analyzed to explore the relationship between SIP1 and HSCR. All exons of SIP1 were amplified and then analyzed by PCR-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. SIP1 expression was determined by immunohistochemistry, Western blot and real-time quantitative PCR. By PCR-RFLP, three different electrophoretic bands of 536, 428 and 257 bp representing different genotypes were demonstrated accordingly. DNA sequencing revealed a heterozygous absence of codon 157 GTG -> GTA exchange at exon 7. Simultaneously, exchanges of GCC -> ACC at codon 351 and ACC -> GCC at codon 395 were also observed in exon 8. All the exchanges caused a missense mutation. By immunohistochemistry, SIP1 was ectopically expressed in the aganglionic segment of HSCR without mutation. For comparison, in HSCR with mutation either in exon 7 or exon 8, SIP1 immunoreactivity disappeared in all structures. The protein and mRNA levels determined by Western blot and real-time quantitative PCR were consistent with that of immunohistochemistry. In summary, mutations of the SIP1 gene were detected in HSCR. These mutations in SIP1 were responsible for the absence of its expression in HSCR and contributed to the pathogenesis of this disease.

AB - PREAMBLE: The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has played an integral role in educating both the metabolic surgical and the medical community at large about the role of innovative and new surgical and/or endoscopic interventions in treating adiposity-based chronic diseases.The mini gastric bypass is also known as the one anastomosis gastric bypass. The IFSO has agreed that the standard nomenclature should be the mini gastric bypass-one anastomosis gastric bypass (MGB-OAGB). The IFSO commissioned a task force (Appendix 1) to determine if MGB-OAGB is an effective and safe procedure and if it should be considered a surgical option for the treatment of obesity and metabolic diseases.The following position statement is issued by the IFSO MGB-OAGB task force and approved by the IFSO Scientific Committee and Executive Board. This statement is based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence. It will be reviewed in 2 years. PMID- 29600341 TI - Fever Burden and Health-Related Quality of Life After Intracerebral Hemorrhage. AB - BACKGROUND: Fever is associated with worse functional outcomes after intracerebral hemorrhage (ICH); however, there are few prospective data to quantify the relationship with health-related quality of life (HRQoL). We tested the hypothesis that increased burden of fever is independently associated with decreased HRQoL at follow-up. METHODS: In this prospective observational cohort study of 106 ICH patients admitted to a tertiary care hospital between 2011 and 2015, we recorded the highest core temperature each calendar day for 14 days after ICH onset. Fever burden was defined as the number of days with a fever >= 100.4 degrees F (38 degrees C). HRQoL outcomes were measured with Neuro-QoL domains of Cognitive Function and Mobility at 28 days, 3 months, and 1 year. Results were analyzed using mixed effects regression analysis. RESULTS: Each additional day with a fever was independently associated with lower Mobility HRQoL (T-score - 0.9, [- 1.6 to - 0.2]; p = 0.01) and Cognitive Function HRQoL (T score - 1.3 [- 2.0 to - 0.6]; p = 0.001) after correction for National Institutes of Health Stroke Scale score on admission, age, and time to follow-up. CONCLUSIONS: Each additional day with a fever was predictive of worse HRQoL domains of Cognitive Function and Mobility after ICH up to 1 year. These data extend previous evidence on the negative association of fever and functional outcomes to the domains of Cognitive Function and Mobility HRQoL. HRQoL outcomes may be a sensitive and powerful way to measure the efficacy of fever control in future research. PMID- 29600340 TI - The effect of hot days on occupational heat stress in the manufacturing industry: implications for workers' well-being and productivity. AB - Climate change is expected to exacerbate heat stress at the workplace in temperate regions, such as Slovenia. It is therefore of paramount importance to study present and future summer heat conditions and analyze the impact of heat on workers. A set of climate indices based on summer mean (Tmean) and maximum (Tmax) air temperatures, such as the number of hot days (HD: Tmax above 30 degrees C), and Wet Bulb Globe Temperature (WBGT) were used to account for heat conditions in Slovenia at six locations in the period 1981-2010. Observed trends (1961-2011) of Tmean and Tmax in July were positive, being larger in the eastern part of the country. Climate change projections showed an increase up to 4.5 degrees C for mean temperature and 35 days for HD by the end of the twenty-first century under the high emission scenario. The increase in WBGT was smaller, although sufficiently high to increase the frequency of days with a high risk of heat stress up to an average of a third of the summer days. A case study performed at a Slovenian automobile parts manufacturing plant revealed non-optimal working conditions during summer 2016 (WBGT mainly between 20 and 25 degrees C). A survey conducted on 400 workers revealed that 96% perceived the temperature conditions as unsuitable, and 56% experienced headaches and fatigue. Given these conditions and climate change projections, the escalating problem of heat is worrisome. The European Commission initiated a program of research within the Horizon 2020 program to develop a heat warning system for European workers and employers, which will incorporate case-specific solutions to mitigate heat stress.

PMID- 29600344 TI - Size Matters: Metastatic Cluster Size and Stromal Recruitment in the Establishment of Successful Prostate Cancer to Bone Metastases. AB - Prostate cancer (PCa) impacts over 180,000 men every year in the USA alone, with 26,000 patients expected to succumb to the disease ( cancer.gov ). The primary cause of death is metastasis, with secondary lesions most commonly occurring in the skeleton. Prostate cancer to bone metastasis is an important, yet poorly understood, process that is difficult to explore with experimental techniques alone. To this end we have utilized a hybrid (discrete-continuum) cellular automaton model of normal bone matrix homeostasis that allowed us to investigate how metastatic PCa can disrupt the bone microenvironment. Our previously published results showed that PCa cells can recruit mesenchymal stem cells (MSCs) that give rise to bone-building osteoblasts. MSCs are also thought to be complicit in the establishment of successful bone metastases (Lu, in Mol Cancer Res 4(4):221-233, 2006). Here we have explored the aspects of early metastatic colonization and shown that the size of PCa clusters needs to be within a specific range to become successfully established: sufficiently large to maximize success, but not too large to risk failure through competition among cancer and stromal cells for scarce resources. Furthermore, we show that MSC recruitment can promote the establishment of a metastasis and compensate for relatively low numbers of PCa cells seeding the bone microenvironment. Combined, our results highlight the utility of biologically driven computational models that capture the complex and dynamic dialogue between cells during the initiation of active metastases. PMID- 29600345 TI - Tips and Tricks for a Laparoscopic Approach to Paracaval Liver Segments. AB - BACKGROUND: A dramatic spread of laparoscopic liver surgery has been experienced over the last years. The approach to paracaval liver segments 1 and 9 is still poorly described in literature, mainly due to its technical demands. OBJECTIVE: The aim of this article was to introduce a safe and effective approach to paracaval liver segments through laparoscopy. METHODS: A minimally invasive approach to resection of Segments 1 and 9 is presented, and an operative set-up is depicted. A step-by-step technique describing the inferior vena cava (IVC) with left and right hepatic venous junction exposure, segmental pedicle isolation, and parenchymal transection is shown through a video document. RESULTS: Postoperative courses were uneventful, and patients were discharged on postoperative day 3. DISCUSSION: The approach to paracaval liver segments requires accurate preoperative case selection, technical, surgical, and anesthesiological expertise in laparoscopic liver surgery, and adequate instrumentary. CONCLUSION: Paracaval segments of the liver can be approached safely through laparoscopy by teams with extensive expertise in the field of laparoscopic liver surgery; however, suspected malignant infiltration of the IVC or unclear preoperative anatomy still contraindicate this approach.

PMID- 29600347 TI - Academic Surgical Oncologists' Productivity Correlates with Gender, Grant Funding, and Institutional NCI Comprehensive Cancer Center Affiliation. AB - BACKGROUND: A scholar's h-index is defined as the number of h papers published, each of which has been cited at least h times. We hypothesized that the h-index strongly correlates with the academic rank of surgical oncologists. METHODS: We utilized the National Cancer Institute (NCI) website to identify NCI-designated Comprehensive Cancer Centers (CCC) and Doximity to identify the 50 highest-ranked general surgery residency programs with surgical oncology divisions. Demographic data of respective academic surgical oncologists were collected from departmental websites and Grantome. Bibliometric data were obtained from Web of Science. RESULTS: We identified 544 surgical oncologists from 64 programs. Increased h index was associated with academic rank (p < 0.001), male gender (p < 0.001), number of National Institutes of Health (NIH) grants (p < 0.001), and affiliation with an NCI CCC (p = 0.018) but not number of additional degrees (p = 0.661) or Doximity ranking (p = 0.102). H-index was a stronger predictor of academic rank (r = 0.648) than total publications (r = 0.585) or citations (r = 0.450). CONCLUSIONS: This is the first report to assess the h-index within academic surgical oncology. H-index is a bibliometric predictor of academic rank that correlates with NIH grant funding and NCI CCC affiliation. We also highlight a previously unexpected and unappreciated gender disparity in the academic productivity of US surgical oncologists. When academic rank was accounted for, female surgical oncologists had lower h-indices compared with their male colleagues. Evaluation of the etiologies of this gender disparity is needed to address barriers to academic productivity faced by female surgical oncologists as they progress through their careers. PMID- 29600348 TI - Analysis of symmetry between lower limbs during gait of older women with bilateral knee osteoarthritis. AB - BACKGROUND: Osteoarthritis (OA) is a common condition in older adults, with high epidemiological, clinical, and economic burden worldwide. In clinical practice, patients with knee OA often walk with abnormal gait patterns because of pain, stiffness and/or mobility dysfunctions. Therefore, assessing the symmetry of the lower limbs might improve the rehabilitation treatment and prescription of walking devices. AIMS: To compare the symmetry of step length and single support phase between lower limbs during gait of older women with bilateral knee OA and asymptomatic controls, and to verify if there is difference between these two groups in relation to velocity, cadence, step length and single support phase. METHODS: This cross-sectional study included a convenience sample of 66 community dwelling older women aged >= 65 years with a medical diagnosis of symptomatic bilateral knee OA (n = 33) and asymptomatic controls (n = 33), matched by age and body mass index. All gait parameters were obtained using the GAITRite(r) system. RESULTS: Mean age of the sample was 72.6 +/- 4.0 years. Participants with OA walked with lower velocity (p = 0.001), cadence (p = 0.009) and step length bilaterally (both p = 0.001). No significant difference was found between groups in the symmetry of step length between lower limbs, single support phase and symmetry of single support phase between lower limbs. CONCLUSION: Older women with bilateral knee OA walk with lower velocity, cadence and step length, but have the same symmetry in the step length and single support phase between lower limbs as asymptomatic older women. PMID- 29600349 TI - Delivery of Brain-Derived Neurotrophic Factor by 3D Biocompatible Polymeric Scaffolds for Neural Tissue Engineering and Neuronal Regeneration. AB - Biopolymers are increasingly employed for neuroscience applications as scaffolds to drive and promote neural regrowth, thanks to their ability to mediate the upload and subsequent release of active molecules and drugs. Synthetic degradable polymers are characterized by different responses ranging from tunable distension or shrinkage to total dissolution, depending on the function they are designed for. In this paper we present a biocompatible microfabricated poly-epsilon caprolactone (PCL) scaffold for primary neuron growth and maturation that has been optimized for the in vitro controlled release of brain-derived neurotrophic factor (BDNF). We demonstrate that the designed morphology confers to these devices an enhanced drug delivery capability with respect to monolithic unstructured supports. After incubation with BDNF, micropillared PCL devices progressively release the neurotrophin over 21 days in vitro. Moreover, the bioactivity of released BDNF is confirmed using primary neuronal cultures, where it mediates a consistent activation of BDNF signaling cascades, increased synaptic density, and neuronal survival. These results provide the proof-of principle on the fabrication process of micropatterned PCL devices, which represent a promising therapeutic option to enhance neuronal regeneration after lesion and for neural tissue engineering and prosthetics. PMID- 29600351 TI - A Digital Language Divide? The Relationship between Internet Medication Refills and Medication Adherence among Limited English Proficient (LEP) Patients. AB - BACKGROUND: Use of an Internet portal to refill medicines positively affects medication adherence among English-speakers. No prior studies, however, have specifically examined the relationship between Internet refills and medication adherence among patients who are limited English proficient (LEP). OBJECTIVES: (1) Examine the relationship between Internet medication refill system use and medication adherence among linguistically diverse patients with chronic conditions and (2) compare this relationship between LEP and English-proficient (EP) patients. DESIGN, PARTICIPANTS, MEASURES: We analyzed 2013-2014 cross sectional data from 509 surveyed adults in the Group Health Cooperative. Surveys were merged with plan enrollment, claims data, and electronic medical records. Medication adherence was calculated by the "Continuous Measure of Medication Gaps" (CMG) method. For Internet refill system use, patients were asked, "Have you used the health systems Internet site to refill any medications in the last 12 months?" LEP status was captured in the electronic medical record by a non English primary language and a claims record of interpreter use in at least one clinical encounter between 2005 and 2012. We used multivariate linear regression models to examine Internet refill system use and medication adherence and compared the association between LEP and EP patients. RESULTS: Three hundred eighty-four patients (75%) had a calculable CMG: 134 EP and 250 LEP in the adherence analyses. In unadjusted analyses, LEP patients had lower use of the Internet refill system (p < .001) and lower adherence versus the EP group (p < .001). In multivariate analyses, LEP status (beta = - 0.022, p = .047) was negatively associated with adherence, while use of the Internet refill system (beta = 0.030, p = .002) was positively associated. In stratified models, use of Internet refills was positively associated with adherence, even when examining LEP (beta = 0.029, p = .003) and EP patients (beta = 0.027, p = .049) separately. CONCLUSIONS: These findings suggest that LEP patients may be under-utilizing a beneficial Internet tool. Should our healthcare systems fail to ensure that LEP patients have full and meaningful access to Internet patient portals, we risk worsening healthcare disparities. PMID- 29600352 TI - Ethnic Disparity in Annual Healthcare Expenditures for Type 2 Diabetes Mellitus in Ningxia, China. AB - BACKGROUND: The incidence of type 2 diabetes mellitus (T2DM) and its complications has been increasing worldwide with an increasing provision of long term medications and health services. This study aimed to assess the healthcare costs for T2DM patients for vulnerable ethnic minority. METHODS: A cross sectional study was conducted from October 13, 2016, to June 19, 2017, in two public hospitals in Ningxia, China. Eligible Hui and Han inpatients were recruited and interviewed. Ethnic disparities in annual healthcare expenditures for T2DM measured from a societal perspective and its associations of expenditures with other factors were analyzed by linear and quantile regressions. RESULTS: Ethnic disparities in annual healthcare expenditures for T2DM were demonstrated, mainly reflecting differences in the cost of productivity loss. The quantile of annual healthcare expenditure showed significant ethnic disparities in T2DM patients with complications. At the 10th to 50th quantiles of healthcare expenditures, Hui patients had significantly lower expenditures than Han patients in both unadjusted and adjusted models. Non-significant difference in expenditures between Hui and Han patients was found at the 90th quantile of expenditure in the unadjusted model, but significantly higher expenditures for Hui patients were shown when adjusted for socioeconomic and clinical factors. CONCLUSION: T2DM Hui patients faced significantly higher expenditures than Han patients when the costs of healthcare were high. Appropriate national policy considering the issue of ethnic minority should be further explored to improve health and subsidize economic burden for T2DM patients. PMID- 29600353 TI - The Variants in the 3' Untranslated Region of the Matrix Metalloproteinase 9 Gene as Modulators of Treatment Outcome in Children with Asthma. AB - PURPOSE: The maintaining of asthma control is difficult due to high variability in response to therapy among patients. Since matrix metalloproteinase 9 (MMP9) is implicated in inflammation and remodeling of asthmatic airways, it could be associated with adequate response to asthma therapy. The aim of this study was to investigate whether variants in 3' end of the MMP9 gene are associated with clinical phenotype and responsiveness to treatment in children with asthma. METHODS: The study included 127 asthmatic children from Slovenia. Variants in the 3' end of the MMP9 gene were analyzed by direct DNA sequencing and the obtained results were correlated with clinical parameters. RESULTS: Two variants were detected, rs13925 and rs20544. For the variant rs20544, statistically significant difference in airway hyperresponsiveness (p = 0.011) and asthma control (p = 0.049) between genotypes was found. Patients with TT genotype had lower airway sensitivity, and after 12 months of treatment showed significant improvement in Asthma Control Test (ACT) scores compared to CC and CT genotype. For the variant rs13925, the association with lung function was observed. The carriers of A allele showed noticeable improvement of lung function after the first 6 months of treatment in comparison to the carriers of G allele (p = 0.046). CONCLUSION: The main finding of our study is the association of MMP9 genotypes rs20544 TT and rs13925 AA and AG with better asthma control, and indirectly better response to treatment. Based on these results, MMP9 deserves further research as a potential predictive biomarker for asthma. PMID- 29600350 TI - Adrenomedullin, a Novel Target for Neurodegenerative Diseases. AB - Neurodegenerative diseases represent a heterogeneous group of disorders whose common characteristic is the progressive degeneration of neuronal structure and function. Although much knowledge has been accumulated on the pathophysiology of neurodegenerative diseases over the years, more efforts are needed to understand the processes that underlie these diseases and hence to propose new treatments. Adrenomedullin (AM) is a multifunctional peptide involved in vasodilation, hormone secretion, antimicrobial defense, cellular growth, and angiogenesis. In neurons, AM and related peptides are associated with some structural and functional cytoskeletal proteins that interfere with microtubule dynamics. Furthermore, AM may intervene in neuronal dysfunction through other mechanisms such as immune and inflammatory response, apoptosis, or calcium dyshomeostasis. Alterations in AM expression have been described in neurodegenerative processes such as Alzheimer's disease or vascular dementia. This review addresses the current state of knowledge on AM and its possible implication in neurodegenerative diseases. PMID- 29600354 TI - Nutritional profile of patients with chronic inflammatory diseases in the age of biologicals. AB - Tumor necrosis factor alpha (TNFalpha) has an important role in the body composition of patients with rheumatoid arthritis (RA), Crohn's disease (CD), and spondyloarthritis (SpA). We aimed to assess the nutritional profile of patients with RA, CD, and SpA undergoing remission with multiple therapies comparing to controls and to analyze the effect of anti-TNFalpha medications in the nutritional parameters of these patients. One hundred thirty-one patients were included: 44 with RA, 43 with CD, and 44 with SpA. Patients receiving anti TNFalpha were compared with those receiving non-biological treatment as well as to controls. Nutritional profile included body mass index (BMI), waist circumference (WC), mid-upper arm circumference, and triceps skinfold measurement. Overweight and obesity were highly prevalent on three assessed groups. In patients with RA, BMI was > 25 kg/m2 in 74.9% patients and 49.2% controls (p < 0.0005); in CD, in 55.7% patients and 41.2% controls (p < 0.0001); and in SpA, in 68.1% patients and 43.5% controls (p < 0.0001). Central obesity was higher in all three disease groups when compared to healthy controls. There was no significant difference on nutritional parameters in patients using or not using anti-TNFalpha medications, except in patients with SpA, in which biologic therapy was significantly associated with lower BMI and WC, when compared to other therapies. Overweight, obesity, and elevated WC were more prevalent in patients with RA, CD, and SpA undergoing remission when compared to controls despite of used therapy. The use of biologic drugs in patients with SpA was associated with a lower BMI and lower WC. PMID- 29600355 TI - Introduction: Esophageal Adenocarcinoma: Updates of Current Status. AB - Esophageal and esophagogastric adenocarcinoma is highly prevalent in the Western populations and is a major cause of cancer-related morbidity and mortality worldwide. The incidence of esophageal adenocarcinoma is rapidly rising in the Western populations. The major predisposing diseases and pathogenesis (gastro esophageal reflux disease, Barrett esophagus, and dysplasia) of the cancer are well known. There is an urgent need for works of the multidisciplinary teams (clinical, pathological, the molecular biology and translational research) for improved outcomes of patients with this cancer. PMID- 29600356 TI - Radiotherapy for Esophageal Adenocarcinoma. AB - Adenocarcinomas occur in distal esophagus and often involve esophagogastric junction. Radiotherapy plays a key role in treatment, often in combination with chemotherapy and surgery in multi-modalities management. For resectable esophageal primaries, neoadjuvant chemoradiotherapy plus surgery can downstage disease and improve outcome over surgery alone. For patients with unresectable primaries or medically unfit for surgery, definitive chemoradiotherapy was found to improve survival over radiotherapy alone. For patients who had residual disease or involved margins after primary surgery, adjuvant chemoradiotherapy in postoperative setting was shown to improve local control and survival. Palliative radiotherapy can also be used to relieve local symptoms like dysphagia or bleeding. Careful radiotherapy planning is required to ensure adequate dose to target volumes without overdose to normal organs. PMID- 29600357 TI - Chemotherapy for Esophageal Adenocarcinoma. AB - Esophageal and esophagogastric junction adenocarcinoma is a distinct entity from esophageal squamous cell carcinoma with respect to etiology and biology despite sharing the same anatomical location. While most international treatment guidelines recommend a similar management strategy for both esophageal squamous and adenocarcinoma histologies, the evidence for treating adenocarcinoma are indeed more often extrapolated from that of gastric carcinoma. In this chapter, the best evidences for the management of this distinct disease with chemotherapy in both curative and palliative clinical settings are presented. PMID- 29600358 TI - Surgical Protocol for Esophageal Adenocarcinoma. AB - Esophagogastrectomy for esophageal adenocarcinoma remains a procedure of significant morbidity and mortality rates. Management should be within the context of a multidisciplinary team. Appropriate patient selection, careful preoperative preparation, meticulous application of surgical technique and perioperative care are essential for success. Enhanced recovery after surgery (ERAS) protocols are evidence based and improve outcome. Standard protocol for open transthoracic esophagectomy is described. PMID- 29600359 TI - Target Therapy for Esophageal Adenocarcinoma. AB - Adenocarcinoma of the esophagus is a deadly disease and median survival of patients with metastatic disease is around 1 year only. There is an unmet need to personalize treatment by identifying molecular targets and respective target therapy in esophageal adenocarcinoma. There has been success in targeting the human epidermal growth factor receptor 2 (HER2) and vasoendothelial growth factor (VEGF) pathway while more failures were encountered in the clinical studies targeting epidermal growth factor (EGFR), mammalian target of rapamycin (mTOR), and mesenchymal-epithelial transition (MET). Studies using immune-checkpoint inhibitors have shown early success, and we await mature data for clinical application. In the chapter, the target therapy and novel treatment strategy will be reviewed. In the future, it is hoped that advances in translational research in targeted therapy against esophageal adenocarcinoma will bring about new progress in clinical practice. PMID- 29600360 TI - Histopathological Assessment for Esophageal Adenocarcinoma. AB - In the World Health Organization (WHO) classification, adenocarcinoma of esophagus comprises preinvasive type (dysplasia), adenocarcinoma, adenoid cystic carcinoma, adenosquamous carcinoma, and mucoepidermoid carcinoma. For adenocarcinoma, it is important to determine the grading of the cancer and histological variants such as signet ring adenocarcinoma. In the current day management of esophageal adenocarcinoma by neoadjuvant therapy, the histology of the cancer and the lymph nodal status may change after the therapy. Tumor regression grading systems could be used to assess the response to the neoadjuvant therapy in esophageal adenocarcinoma. PMID- 29600361 TI - Macroscopic Assessment and Cut Up of Endoscopic Resection Specimens for Early Esophageal Glandular Malignancies. AB - Pathological assessment of tissue is the gold standard for diagnosis and staging of neoplasia and provides key prognostic information for clinical management. Proper macroscopic assessment and cut-up technique is essential to ensure that the overall assessment is correct and reproducible. Endoscopic mucosal resection is a technique used for removing early neoplastic glandular lesions of the esophagus at the level of submucosa. Here, we describe the macroscopic assessment and dissection techniques used for the routine handling of endoscopic mucosal resection specimens in the clinical laboratory. PMID- 29600362 TI - Processing of Surgical Specimen (Esophagogastrectomy) for Esophageal Adenocarcinoma. AB - An esophagogastrectomy is a surgical procedure that is performed for treatment of confirmed localized esophageal and esophagogastric junction adenocarcinoma. Proper macroscopic assessment and cut-up technique is essential to ensure that the overall assessment is correct and reproducible. Here, we describe a standard for macroscopic assessment and dissection to be used for routine handling of esophagogastrectomy specimens in the clinical laboratory. PMID- 29600363 TI - Application of Pathological Staging in Esophageal Adenocarcinoma. AB - Staging is one of the most important factors that determine the prognosis of the patients with esophageal adenocarcinoma. The current staging protocol includes parameters-extent of tumor (T), lymph node status (N), presence of distant metastasis (M), and grade of the adenocarcinoma (G). In addition, different criteria are used in patients with and without neoadjuvant therapy. The silent aspects of the use of new staging protocol are discussed. PMID- 29600364 TI - Application of Tissue Microarray in Esophageal Adenocarcinoma. AB - Tissue microarray technology could allow immunohistochemical staining or in situ hybridization on hundreds of different tissue samples simultaneously. It allows faster analysis and considerably reducing costs incurred in staining. The technique also provides a high-throughput analysis of multiple tissues for the different types of research. In the literature, many researches of esophageal adenocarcinoma use tissue microarray to enhance the output. In this chapter, we have a brief overview of tissue microarray technologies, the advantages and disadvantages of tissue microarray, and related troubleshootings. PMID- 29600365 TI - Predictive Marker: HER2 in Esophageal Adenocarcinoma. AB - HER2 positivity is based on the fundamental principle of amplification of the human epidermal growth factor receptor 2 (HER2) gene resulting in overexpression of the protein products . Arising from that a "HER2-positive cancer" is one that shows HER2 gene amplification and resultant protein expression as demonstrated by in situ hybridization and immunohistochemistry, respectively. Testing of the HER2 status is crucial to ensure selection of the correct patient who may benefit from target therapy for esophageal adenocarcinoma. Accurate testing is dependent on several pre-analytical and analytical factors including sample selection, laboratory techniques, and accurate interpretation of HER2 test results. PMID- 29600366 TI - Whole-Slide Imaging for Esophageal Adenocarcinoma. AB - Whole-slide imaging revolutionizes the field of pathology especially in the areas of facilitation of research, long-term storages, exchange of information, and image analysis. In this process, a scanning equipment (scanner) scans the whole glass slide into a digital file. In research in esophageal adenocarcinoma or other cancers, whole-slide imaging could help in production of high-resolution images for studying and sharing of research information, assessment of tissue microarray slides as well as allowing digital image analysis of the tissue information such as level of staining (e.g., HER2) in a more efficient and objective manner. In this chapter, we will elaborate the concepts, advantages, barriers, and the operations of whole-slide imaging scanning. PMID- 29600367 TI - Animal Model: Reflux Models in Esophageal Adenocarcinoma. AB - Many mouse models have been developed to mimic the inflammation-metaplasia dysplasia-carcinoma sequence seen in the gastroesophageal reflux disease (GERD) Barrett's esophagus-esophageal adenocarcinoma progression. Surgical reflux models in mice are technically challenging due to the small size and intolerance to surgical stress of mice. Herein, we detail three representative surgical procedures that allow for creation of an esophageal adenocarcinoma model in mice, either with or without the use of carcinogens. Additionally, we describe a genetic model that shows spontaneous development of esophageal adenocarcinoma. PMID- 29600368 TI - Animal Model: Xenograft Mouse Models in Esophageal Adenocarcinoma. AB - Researchers often use murine models of esophageal cancer to evaluate novel therapies prior to clinical protocol treatment. Subcutaneous xenograft models are often used for testing the efficacy of anticancer agents in many cancers including esophageal adenocarcinoma. However, mice subcutaneous esophageal adenocarcinoma models only represent local tumor growth and do not provide any information about a survival benefit for a particular anticancer regimen, which is very crucial for experimental treatment efficacy. In addition, anticancer agents may well inhibit subcutaneous tumor growth without effecting overall animal survival. Herein, we describe a peritoneal dissemination mouse xenograft model for survival outcome analysis with intraperitoneal injection of human esophageal adenocarcinoma cell lines. PMID- 29600369 TI - Identification of Cancer Stem Cells in Esophageal Adenocarcinoma. AB - Cancer stem cells (CSCs) are a subpopulation of cancer cells that have the ability to self-renew and to generate differentiated cells of various lineages. Due to their specific morphological and biological features, they are often resistant to therapy and in turn lead to metastasis and cancer recurrence. Because of their crucial roles in carcinogenesis and patient prognosis, identification and isolation of CSCs have become an important part of improved cancer management regime. Isolation, characterization, and development of targeted therapy against CSCs have potential efficacy in treating esophageal cancer. In addition, CSCs can act as a predictive tool for chemoradiotherapy response in esophageal adenocarcinoma. Different methods including functional assays, cell sorting using various intracellular, and cell surface markers and xenotransplantation techniques are used for the identification and separation of CSCs in different cancers. None of these methods solely can guarantee complete isolation of CSC population, thus a combination of methods could be used for reliable detection and isolation of CSCs. Here, we describe the identification and isolation of CSCs from esophageal adenocarcinoma cells by cell sorting after Hoechst 33342 staining followed by in vitro functional assays, and in vivo xenograft techniques. PMID- 29600370 TI - Circulatory Tumor Cells in Esophageal Adenocarcinoma. AB - While circulating tumor cells (CTCs) within peripheral blood of cancer patients are no new phenomenon in many carcinomas, there is a lack of information on the biological and clinical implications of CTCs in esophageal adenocarcinomas. Limited evidence suggests that the CTCs are frequently detected in esophageal adenocarcinomas when compared to esophageal squamous cell carcinoma suggesting the potential difference in the pathogenesis between these two carcinomas. In addition, the varied CTC levels between adenocarcinoma and squamous cell carcinomas of the esophagus could be attributed to the varied expression pattern of epithelial markers such as epithelial cell adhesion molecule (EpCAM) and cytokeratin (CK). In esophageal adenocarcinomas, CTC levels correlated with pathological T stages, lymph node metastasis, and patient survival. Thus, detection of CTCs potentially acts as a noninvasive and real-time biomarker for predicting patient prognosis in esophageal adenocarcinomas. Although the CTC detection is currently performed using various methods, the only Food and Drug Administration (FDA) of USA approved CTC detection method in clinics is the CELLSEARCH(r) system. This chapter will discuss various biological characteristics of CTC and its potential implications in esophageal adenocarcinomas. In addition, a quick overview of CTC detection methodology is outlined. PMID- 29600371 TI - Liquid Biopsy for Investigation of Cancer DNA in Esophageal Adenocarcinoma: Cell Free Plasma DNA and Exosome-Associated DNA. AB - Liquid biopsy of cancers is an area of increasing interest in medical practice for the surveillance, management, and potential detection of malignant cells, using minimally invasive collection of body fluids. A liquid biopsy is particularly useful for metastatic cancers, which may be difficult to be sampled by core biopsy, due to difficulty of access or an occult location. Access to DNA shed from esophageal adenocarcinoma can enable the detection of mutations confirming the presence of malignant cells or the evolution of clonal lines with altered treatment response profiles. In this chapter, we detail a method for the isolation of cell-free DNA from blood plasma and DNA associated with exosomes in blood from patients with esophageal adenocarcinoma. PMID- 29600372 TI - Somatic DNA Copy-Number Alterations Detection for Esophageal Adenocarcinoma Using Digital Polymerase Chain Reaction. AB - Somatic copy-number alterations are commonly found in cancer and play key roles in activating oncogenes and deactivating tumor suppressor genes. Digital polymerase chain reaction is an effective way to detect the changes in copy number. In esophageal adenocarcinoma, detection of somatic copy-number alterations could predict the prognosis of patients as well as the response to therapy. This chapter will review the methods involved in digital polymerase chain reaction for the research or potential clinical applications in esophageal adenocarcinoma. PMID- 29600374 TI - DNA Genome Sequencing in Esophageal Adenocarcinoma. AB - Next-generation sequencing refers to the high-throughput DNA sequencing technologies, which are capable of sequencing large numbers of different DNA sequences in a single/parallel reaction. It is a powerful tool to identify inherited and acquired genetic alterations associated with the development of esophageal adenocarcinoma. Whole-genome sequencing is the most comprehensive but expensive, whereas whole-exome sequencing is cost-effective but it only works for the known genes. Thus, second-generation sequencing methods can provide a complete picture of the esophageal adenocarcinoma genome by detecting and discovering different type of alterations in the cancer. This would help in diagnostics and will further help in developing personalized medicine in esophageal adenocarcinoma. PMID- 29600373 TI - Targeted Single Gene Mutation in Esophageal Adenocarcinoma. AB - Esophageal adenocarcinoma is heterogeneous and studies have reviewed many important mutations that contribute to the pathogenesis of the cancer. These discoveries have helped paved the way into identifying new gene markers or gene targets to develop novel molecular directed therapy for better patient outcomes in esophageal adenocarcinoma. Despite the recent bloom in next-generation sequencing, Sanger sequencing still represents the gold standard method for the study of the driver genes in esophageal adenocarcinoma. This chapter focuses on the sequencing techniques in identification of single gene mutations. PMID- 29600375 TI - Epigenetics: DNA Methylation Analysis in Esophageal Adenocarcinoma. AB - The aberrant DNA methylation has been noted to occur at promoter of tumor suppressor, cell adhesion, DNA repair, and other growth regulating genes during the progression of nonneoplastic esophageal mucosa to Barrett esophagus to esophageal adenocarcinoma. Methylation-mediated silencing of individual gene or concurrent loss of a number of genes plays crucial roles in dysplasia-metaplasia neoplasia sequence of esophageal adenocarcinoma. In addition, promoter methylation of genes had shown significant prognostic potential in patients with esophageal adenocarcinoma. Thus, determination of methylation status of genes of interest can be used as a molecular marker for risk stratification and/or better prognosis of patients with esophageal adenocarcinoma. There are a number of methods including bead array, PCR and sequencing, pyrosequencing, methylation specific PCR, and PCR with high-resolution melt curve available to determine the methylation status of particular gene of interest. Herein, we describe the polymerase chain reaction followed by sequencing-based protocol for identifying DNA methylation status in esophageal adenocarcinoma. PMID- 29600376 TI - Detection and Quantification of MicroRNAs in Esophageal Adenocarcinoma. AB - MicroRNAs (miRNAs) are a class of small, noncoding RNAs that have been emerging as novel regulators in esophageal adenocarcinoma. Their role has been established in various aspects of esophageal adenocarcinoma including carcinogenesis, progression, treatment, and prognosis. Therefore, miRNA detection, profiling, and quantification have become extremely important for scientists and clinicians. As miRNAs are small, their detection can be challenging. There have been various methods developed to detect and/or quantify miRNAs. This chapter aims to introduce the fundamentals and methods of the most commonly used approaches including miRNA microarrays and quantitative real-time polymerase chain reaction (RT-qPCR) to detect and quantify miRNAs in esophageal adenocarcinoma. PMID- 29600377 TI - RNA Interference-Mediated Gene Silencing in Esophageal Adenocarcinoma. AB - RNA interference (RNAi) is a normal physiological mechanism in which a short effector antisense RNA molecule regulates target gene expression. It is a powerful tool to silence a particular gene of interest in a sequence-specific manner and can be used to target against various molecular pathways in esophageal adenocarcinoma by designing RNAi targeting key pathogenic genes. RNAi-based therapeutics against esophageal adenocarcinoma can be developed using different strategies including inhibition of overexpressed oncogenes, blocking cell division by interfering cyclins and related genes or enhancing apoptosis by suppressing anti-apoptotic genes. In addition, RNAi against multidrug resistance genes or chemo-resistance targets may provide promising cancer therapeutic options. Here, we describe RNAi technology using MET, a proto-oncogene in esophageal adenocarcinoma cells, as a model target. Lentiviral particles expressing MET shRNA was used to silence MET genes. Then, Western blot analysis was performed to confirm MET knockdown. PMID- 29600378 TI - Proteomic Protocol in Esophageal Adenocarcinoma. AB - The technique of surface-enhanced laser desorption/ionization time-of-flight SELDI-TOF mass spectrometry could be used to establish serum or plasma proteomic profiles in esophageal adenocarcinoma. The protein profiles in patients may be used to predict survival and monitor response to chemotherapy in patients with esophageal adenocarcinoma. Here, a protocol for sample preparation from esophageal adenocarcinoma, analysis of proteomic profiles, and collection of protein fractions for identification of significant peaks is presented. PMID- 29600379 TI - A new approach to the renewable energy-growth nexus: evidence from the USA. AB - The climate change is one of the leading problems in the today's world. The rise of the renewable energy meets the sustainable growth objectives since it can decelerate the climate change. For this purpose, this paper investigates the relationship between the renewable energy consumption and the economic growth in the United States (USA). Theoretically, the paper constructs the growth model that captures the effects of the economic complexity indicator as a measure of capabilities and productivity for exporting the "complex" (high value-added) products. Empirically, the paper uses the Autoregressive Distributed Lag (ARDL) estimations and observes that both the economic complexity and the renewable energy consumption lead to a higher rate of economic growth in the USA for the period from 1965 to 2016. The paper also discusses the potential policy implications of the results for achieving the sustainable growth objectives. PMID- 29600380 TI - Increasing water productivity, nitrogen economy, and grain yield of rice by water saving irrigation and fertilizer-N management. AB - The looming water resources worldwide necessitate the development of water-saving technologies in rice production. An open greenhouse experiment was conducted on rice during the summer season of 2016 at Huazhong Agricultural University, Wuhan, China, in order to study the influence of irrigation methods and nitrogen (N) inputs on water productivity, N economy, and grain yield of rice. Two irrigation methods, viz. conventional irrigation (CI) and "thin-shallow-moist-dry" irrigation (TSMDI), and three levels of nitrogen, viz. 0 kg N ha-1 (N0), 90 kg N ha-1 (N1), and 180 kg N ha-1 (N2), were examined with three replications. Study data indicated that no significant water by nitrogen interaction on grain yield, biomass, water productivity, N uptake, NUE, and fertilizer N balance was observed. Results revealed that TSMDI method showed significantly higher water productivity and irrigation water applications were reduced by 17.49% in TSMDI compared to CI. Thus, TSMDI enhanced root growth and offered significantly greater water saving along with getting more grain yield compared to CI. Nitrogen tracer (15N) technique accurately assessed the absorption and distribution of added N in the soil crop environment and divulge higher nitrogen use efficiency (NUE) influenced by TSMDI. At the same N inputs, the TSMDI was the optimal method to minimize nitrogen leaching loss by decreasing water leakage about 18.63%, which are beneficial for the ecological environment. PMID- 29600381 TI - Spectral fitting approach for the determination of enrichment and contamination factors in mining sediments using laser-induced breakdown spectroscopy. AB - Monitoring of pollution index values in sediments is crucial in assessing the environmental impacts of toxic metals in a given location. These indices are typically acquired using elaborate and tedious calibration curve-dependent techniques such as (inductively coupled plasma - optical emission spectroscopy) ICP-OES and (atomic absorption spectroscopy) AAS. In this study, laser-induced breakdown spectroscopy (LIBS) was used as a simple and fast alternative method for estimating enrichment factor (EF) and contamination factor (CF) of the sediment samples obtained from selected mining sites. Quantitative analyses of three metal targets (Cd, Pb, and Zn) were done using a calibration-free LIBS method based on the Boltzmann population distribution. Both the EF and CF values calculated from classical ICP-OES method provided significantly high correspondence with the respective EF (R2 = 0.8862-0.9770, p < 0.01-0.05) and CF (R2 = 0.9454-0.9714, p < 0.01) obtained from the developed LIBS method. The intensity-based LIBS approach identified samples AC2 and CCC as the ones with the highest and lowest pollution index values, respectively. The same observation was seen using the concentration-based ICP-OES technique which showed good correlation between the two methods. The correlation results showed the potential of the curve-fitting LIBS analysis in evaluating the level of metal contamination in an area without the preparation of matrix-matched calibration curves. PMID- 29600382 TI - Optimization of photo-Fenton process for the treatment of prednisolone. AB - Prednisolone is a widely prescribed synthetic glucocorticoid and stated to be toxic to a number of non-target aquatic organisms. Its extensive consumption generates environmental concern due to its detection in wastewater samples at concentrations ranged from ng/L to MUg/L that requests the application of suitable degradation processes. Regarding the actual treatment options, advanced oxidation processes (AOPs) are presented as a viable alternative. In this work, the comparison in terms of pollutant removal and energetic efficiencies, between different AOPs such as Fenton (F), photo-Fenton (UV/F), photolysis (UV), and hydrogen peroxide/photolysis (UV/H2O2), was carried out. Light diode emission (LED) was the selected source to provide the UV radiation. The UV/F process revealed the best performance, reaching high levels of both degradation and mineralization with low energy consumption. Its optimization was conducted and the operational parameters were iron and H2O2 concentrations and the working volume. Using the response surface methodology with the Box-Behnken design, the effect of independent variables and their interactions on the process response were effectively evaluated. Different responses were analyzed taking into account the prednisolone removal (TOC and drug abatements) and the energy consumptions associated. The obtained model showed an improvement of the UV/F process when treating smaller volumes and when adding high concentrations of H2O2 and Fe2+. The validation of this model was successfully carried out, having only 5% of discrepancy between the model and the experimental results. Finally, the performance of the process when having a real wastewater matrix was also tested, achieving complete mineralization and detoxification after 8 h. In addition, prednisolone degradation products were identified. Finally, the obtained low energy permitted to confirm the viability of the process. PMID- 29600383 TI - Particulate matter on two Prunus spp. decreases survival and performance of the folivorous beetle Gonioctena quinquepunctata. AB - Woody plants growing along streets and construction sites play an important role in removing harmful particulate matter (PM). Researchers rarely consider the impact of different types and size fractions of PM deposited on the leaves on insect folivores. We determined differences in the accumulation of cement and roadside PM on the leaves of two Prunus species (P. padus and P. serotina) with different leaf surface structures. We also determined the effect of PM on the beetle Gonioctena quinquepunctata, the main pest of these plants. Saplings were artificially dusted in greenhouses and leaves were utilised for larval and adult insect stages feeding in laboratory conditions. Road PM accumulated in greater amounts than did cement PM, regardless of plant species. For both PM sources, P. padus accumulated twofold more than did P. serotina. Insect survival was negatively affected by PM pollution; however, neither Prunus species nor PM source variant significantly affected masses of larvae and pupae, duration of larval and pupal development or relative growth rates. The experiment showed strong negative influences of PM were noted only for adult insects, due to the grazing period being longer than that in larvae. The mass of adult insects and the efficiency of conversion of ingested food (ECI) were lower for insects exposed to PM than those for control insects. Insects compensated for lower ECI by eating a greater total amount of food (TFE). Adult insects gained significantly higher mass when fed with P. serotina than with P. padus. The effect of PM on analysed plant metabolites was insignificant. Only Prunus sp. and date of collection affected the level of condensed tannins and total phenols. Our results indicate that, when investigating the effect of the host plant on folivore performance, the accumulation of PM, as well as its type and quantity, should be taken into account. PMID- 29600384 TI - Paclitaxel as Albumin-Bound Nanoparticles with Gemcitabine for Untreated Metastatic Pancreatic Cancer: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - As part of the single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited Celgene Ltd to submit clinical and cost-effectiveness evidence for paclitaxel as albumin-bound nanoparticles (Nab Pac) in combination with gemcitabine (Nab-Pac + Gem) for patients with untreated metastatic pancreatic cancer. The STA was a review of NICE's 2015 guidance (TA360) in which Nab-Pac + Gem was not recommended for patients with untreated metastatic pancreatic cancer. The review was prompted by a proposed Patient Access Scheme (PAS) discount on the price of Nab-Pac and new evidence that might lead to a change in the guidance. The Liverpool Reviews and Implementation Group at the University of Liverpool was the Evidence Review Group (ERG). This article summarises the ERG's review of the company's evidence submission for Nab-Pac + Gem, and the Appraisal Committee (AC) decision. The final scope issued by NICE listed three comparators: gemcitabine monotherapy (Gem), gemcitabine in combination with capecitabine (Gem + Cap), and a combination of oxaliplatin, irinotecan, leucovorin and fluorouracil (FOLFIRINOX). Clinical evidence for the comparison of Nab-Pac + Gem versus Gem was from the phase III CA046 randomized controlled trial. Analysis of progression-free survival (PFS) and overall survival (OS) showed statistically significant improvement for patients treated with Nab-Pac + Gem versus Gem. Clinical evidence for the comparison of Nab-Pac + Gem versus FOLFIRINOX and versus Gem + Cap was derived from a network meta analysis (NMA). Results of the NMA did not indicate a statistically significant difference in OS or PFS for the comparison of Nab-Pac + Gem versus either Gem + Cap or FOLFIRINOX. The ERG's main concerns with the clinical effectiveness evidence were difficulties in identifying the patient population for whom treatment with Nab-Pac + Gem is most appropriate, and violation of the proportional hazards (PH) assumption in the CA046 trial. The ERG highlighted methodological issues in the cost-effectiveness analysis pertaining to the modelling of survival outcomes, estimation of drug costs and double counting of adverse-event disutilities. The AC accepted all the ERG's amendments to the company's cost-effectiveness model; however, these did not make important differences to the incremental cost-effectiveness ratios (ICERs). The company's base-case ICER was L46,932 per quality-adjusted life-year (QALY) gained for the comparison of Nab-Pac + Gem versus Gem. Treatment with Nab-Pac + Gem was dominated both by treatment with Gem + Cap and with FOLFIRINOX in the company's base case. The AC concluded that the most plausible ICER for treatment with Nab Pac + Gem versus Gem was in the range of L41,000-L46,000 per QALY gained. The AC concluded that Nab-Pac + Gem was not cost effective compared with Gem + Cap or FOLFIRINOX, and accepted that treatment with Nab-Pac + Gem met the end-of-life criteria versus Gem but did not consider Nab-Pac + Gem to meet the end-of-life criteria compared with Gem + Cap or FOLFIRINOX. The AC also concluded that although patients who would receive Nab-Pac + Gem rather than FOLFIRINOX or Gem + Cap were difficult to distinguish, they were identifiable in clinical practice. The AC recommended treatment with Nab-Pac + Gem for patients with untreated metastatic pancreatic cancer for whom other combination chemotherapies were unsuitable and who would otherwise receive Gem. PMID- 29600385 TI - Long-term results of a modified Spitzy shelf operation for developmental dysplasia of the hip in adults and adolescents. AB - The purpose of the current study was to retrospectively evaluate the long-term outcome of our shelf operation for acetabular dysplasia in adults and adolescents. We evaluated the outcome of shelf operation performed in 35 hips of 32 patients with acetabular dysplasia between 1978 and 1996. The mean age at the time of surgery was 30.6 years, and the mean follow-up period was 25.9 years. The pre-operative stage of osteoarthritis was Tonnis grade 0 in 12 hips and grade 1 in 23 hips. Clinical evaluation using the JOA hip score showed more than 85 of 100 points over 25 years. Radiologically, acetabular index was significantly improved after operation. Osteoarthritis deteriorated to grade 3 in 8 of 35 hips (23%) at an average 17.1 years, and accordingly 3 of those 8 hips were converted to THA. The shelf height was significantly higher in those which advanced to grade 3 than in those which did not. There were no significant differences in mean sharp angle, CE angle, AHI, and roundness index. Mean survival was 74% with grade 3 as the endpoint and 72% with THA conversion as the endpoint. Shelf operation provides satisfactory long-term outcome in adults and adolescents with acetabular dysplasia. Higher location of the shelf is a risk factor for advancement of osteoarthritis, whereas sphericity of the femoral head does not affect the long-term results. Further studies are needed to clarify the risk factors about OA progression among the patients with acetabular dysplasia, like as the assessment of three-dimensional morphology of hip joints. PMID- 29600386 TI - Survival impact of post-progression chemotherapy in advanced gastric cancer: systematic review and meta-analysis. AB - PURPOSE: We conducted a systematic review and meta-analysis on survival impact of post-progression chemotherapy (post-Cx) after first-line chemotherapy (1st-Cx) and after second-line chemotherapy (2nd-Cx), and survival benefit of third-line chemotherapy (3rd-Cx) for advanced gastric cancer (AGC). METHODS: Phase III trials of systemic chemotherapy for AGC published in English between 2005 and 2015 or presented at annual meetings of ASCO or ESMO between 2013 and 2015 were searched. Numbers of patients, types of chemotherapy, patient baseline, proportion of patients receiving post-Cx (post-Cx%), median progression-free survival (mPFS), and median overall survival (mOS) of each treatment arm were surveyed; trials not reporting these parameters were excluded. Median post progression survival (mPPS) was calculated as the difference between mOS and mPFS. Weighted Spearman's correlation coefficients between post-Cx% and survival outcomes (mOS and mPPS) were calculated. The effect of post-Cx% on survival outcomes adjusted for the types of chemotherapy and patient characteristics was evaluated by meta-regression. RESULTS: Overall, 25 phase III trials of AGC were selected: 15 trials with 31 arms for 1st-Cx, and 10 trials with 16 arms for 2nd Cx. Weighted Spearman's correlation coefficients for post-Cx% and mOS/mPPS were 0.520/0.739 for 1st-Cx, and 0.767/0.823 for 2nd-Cx. Meta-regression analyses adjusting for types of chemotherapy, age, and PS showed that a 10% increase in post-Cx% was associated with prolongation of mOS by 1.033 months for 1st-Cx and 0.344 months for 2nd-Cx. CONCLUSIONS: Post-Cx% both after 1st-Cx and 2nd-Cx were correlated with mOS/mPPS, suggesting a survival benefit of 3rd-Cx in addition to that of 2nd-Cx for AGC.

AB - The plant stress hypothesis posits that a herbivore's reproductive success increases when it feeds on stressed plants, while the plant vigor hypothesis predicts that a herbivore preferentially feeds on more vigorous plants. We examined these opposing hypotheses by growing spider mites (Tetranychus urticae) on the leaves of stressed and healthy (vigorous) cucumber plants. Host plants were grown under controlled conditions at low, moderate, and high concentrations of NaCl (to induce salinity stress), at low, moderate, and high fertilizer concentrations (to support growth), and without these additions (control). The effects of these treatments were evaluated by measuring fresh and dry plant biomass, carotenoid and chlorophyll content, antioxidant enzyme activity, and concentrations of PO43-, K+, and Na+ in plant tissues. The addition of low concentrations of fertilizer increased dry mass, protein, and carotenoid content relative to controls, suggesting a beneficial effect on plants. The highest NaCl treatment (2560 mg L-1) resulted in increased Na+ and protein content relative to control plants, as well as reduced PO43-, K+, and chlorophyll levels and reduced catalase and ascorbate peroxidase enzyme activity levels. Analysis of life table data of T. urticae mites raised on leaves from the aforementioned plant groups showed the intrinsic rate of increase (r) for mites was 0.167 day-1 in control specimens, 0.125 day-1 for mites reared on plants treated with a moderate concentration of fertilizer (10 mL L-1), and was highest (0.241 day-1) on plants grown under moderate salinity conditions (1920 mg L-1 NaCl). Reproductive success of T. urticae did not differ on plants watered with a moderate concentration of NaCl or a high concentration of fertilizer. The moderately-stressed plants formed a favorable environment for the development and reproduction of spider mites, supporting the plant stress hypothesis. PMID- 29600388 TI - Alpha-synuclein is present in dental calculus but not altered in Parkinson's disease patients in comparison to controls. AB - INTRODUCTION: In autopsy cases staged for sporadic Parkinson's disease (PD), the neuropathology is characterized by a preclinical phase that targets the enteric nervous system of the gastrointestinal tract (GIT). Therefore, the ENS might be a source of potential (presymptomatic) PD biomarkers. METHODS: In this clinically based study, we examined the alpha-synuclein (alphaSyn) concentration in an easily accessible protein storage medium of the GIT, dental calculus, in 21/50 patients with PD and 28/50 age- and gender-matched controls using ELISA. RESULTS: alphaSyn was detectable in dental calculus and the median concentration in the control patients was 8.6 pg/mg calculus (interquartile range 2.6-13.1 pg/mg). alphaSyn concentrations were significantly influenced by blood contamination and samples with a hemoglobin concentration of > 4000 ng/mL were excluded. There was no significant difference of alphaSyn concentrations in the dental calculus of PD patients (5.76 pg/mg, interquartile range 2.91-9.74 pg/mg) compared to those in controls (p = 0.40). CONCLUSION: The total alphaSyn concentration in dental calculus is not a suitable biomarker for sporadic PD. Disease-related variants such as oligomeric or phosphorylated alphaSyn in calculus might prove to be more specific. PMID- 29600389 TI - A novel frameshift variant in the CADASIL gene NOTCH3: pathogenic or not? AB - Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) represents the most common monogenic cause of adult onset ischemic stroke and vascular dementia. It is caused by heterozygous missense mutations in the NOTCH3 gene, encoding a transmembrane receptor protein on vascular smooth muscle cells. Classical CADASIL mutations affect conserved cysteine residues of the Notch3 protein. By contrast, the role of non-canonical genetic variation in NOTCH3, in particular of variants causing a hypomorphic Notch3 protein, is subject to an ongoing scientific debate. In this context, we here report a novel NOTCH3 frameshift variant in exon 18 (NM_000435.2: c.2853_2857delTCCCG), causing a frameshift and introducing a premature stop codon, which was detected in a 43-year-old woman and her father. Both carriers of the variant were carefully evaluated, including serial follow-up in the index. Neither clinical nor imaging features provided convincing evidence for a classical CADASIL phenotype, thus reinforcing the concept of hypomorphic NOTCH3 variants most likely not being causative for CADASIL. Our finding, which is discussed in the light of the published literature, has practical implications for interpreting results of NOTCH3 molecular genetic testing as well as patient counseling. PMID- 29600391 TI - Safety and Antioxidant Efficacy Profiles of Rutin-Loaded Ethosomes for Topical Application. AB - Topical application of dermocosmetics containing antioxidant and/or the intake of antioxidants through diet or supplementation are remarkable tools in an attempt to slow down some of the harmful effects of free radicals. Rutin is a strong antioxidant compound used in food and pharmaceutical industries. It was established that rutin presents a low skin permeation rate, a property that could be considered an inconvenience to the satisfactory action for a dermocosmetic formulation to perform its antioxidant activity onto the skin. Therefore, it is indispensable to improve its delivery, aiming at increasing its antioxidant capacity in deeper layers of the epidermis, being a possibility to associate the rutin to liposomal vesicles, such as ethosomes. Thus, in this work, the pre clinical safety of rutin-loaded ethosomes was investigated employing an in vitro method, and the clinical safety and efficacy were also assessed. Rutin-loaded ethosomes were efficaciously obtained in a nanoscale dimension with a relevant bioactive compound loading (80.2%) and provided antioxidant in vitro activity in comparison with the blank sample. Pre-clinical and clinical safety assays assured the innocuous profile of the rutin-loaded ethosomes. The ethosomes containing the bioactive compound accomplished a more functional delivery system profile, since in the tape stripping assay, the deeper layers presented higher rutin amounts than the active delivered in its free state. However, the ex vivo antioxidant efficacy test detected no positive antioxidant activity from the rutin-loaded ethosomes, even though the in vitro assay demonstrated an affirmative antioxidant action.

PMID- 29600390 TI - Supervised versus unsupervised technology-based levodopa monitoring in Parkinson's disease: an intrasubject comparison. AB - We aimed to assess the intrasubject reproducibility of a technology-based levodopa (LD) therapeutic monitoring protocol administered in supervised versus unsupervised conditions in patients with Parkinson's disease (PD). The study design was pilot, intrasubject, single center, open and prospective. Twenty patients were recruited. Patients performed a standardized monitoring protocol instrumented by an ad hoc embedded platform after their usual first morning LD dose in two different randomized ambulatory sessions: one under a physician's supervision, the other self-administered. The protocol is made up of serial motor and non-motor tests, including alternate finger tapping, Timed Up and Go test, and measurement of blood pressure. Primary motor outcomes included comparisons of intrasubject LD subacute motor response patterns over the 3-h test in the two experimental conditions. Secondary outcomes were the number of intrasession serial test repetitions due to technical or handling errors and patients' satisfaction with the unsupervised LD monitoring protocol. Intrasubject LD motor response patterns were concordant between the two study sessions in all patients but one. Platform handling problems averaged 4% of total planned serial tests for both sessions. Ninety-five percent of patients were satisfied with the self administered LD monitoring protocol. To our knowledge, this study is the first to explore the potential of unsupervised technology-based objective motor and non motor tasks to monitor subacute LD dosing effects in PD patients. The results are promising for future telemedicine applications. PMID- 29600393 TI - Chlorhexidine use in adult patients on ICU.

PMID- 29600395 TI - Deep brain stimulation of the thalamic ventral intermediate nucleus for Benedikt's syndrome mainly present as tremor: a long-term case observation. AB - Benedikt's syndrome (BS) is caused by the lesion in the midbrain and specifically manifests a series of symptoms, including ipsilateral third nerve palsy, contralateral tremor, hemiataxia, and hyperactive tendon reflexes. Deep brain stimulation (DBS) for BS emerges as a new approach and achieves successfully results. We report a successful case report of thalamic ventral intermediate (VIM) nucleus DBS for a patient with BS. During follow-up of 3 years, DBS successfully control the tremor and greatly improve his living and working quality. We consider that VIM DBS may have sustained benefit for refractory BS that mainly presents as tremor. PMID- 29600396 TI - "You Worry, 'cause You Want to Give a Reasonable Account of Yourself": Gender, Identity Management, and the Discursive Positioning of "Risk" in Men's and Women's Talk About Heterosexual Casual Sex. AB - Heterosexual casual sex is routinely depicted as a physically, socially, and psychologically "risky" practice. This is the case in media accounts, psychological research, and other academic work. In this article, we examine 15 men's and 15 women's talk about casual sex from a discursive psychological stance to achieve two objectives. Firstly, we confirm the categories of risk typically associated with casual sex but expand these to include a domain of risks related to (gendered) identities and representation. Men's talk of risk centered on concerns about sexual performance, whereas women's talk centered on keeping safe from violence and sexual coercion. The notion of a sexual reputation was also identified as a risk and again manifested differently for men and women. While women were concerned about being deemed promiscuous, men displayed concern about the quality of their sexual performance. Secondly, within this talk about risks of casual sex, the participants' identities were identified as "at risk" and requiring careful management within the interview context. This was demonstrated by instances of: keeping masculinity intact in accounts of no erection, negotiating a responsible subject position, and crafting agency in accounts of sexual coercion-in the participants' talk. We argue that casual sex, as situated within dominant discourses of gendered heterosexuality, is a fraught practice for both men and women and subject to the demands of identity representation within co-present interactions.

PMID- 29600400 TI - Do patient characteristics predict which patients with overactive bladder benefit from a higher fesoterodine dose? AB - INTRODUCTION AND HYPOTHESIS: We sought to determine whether baseline characteristics predict which overactive bladder (OAB) patients benefit from fesoterodine 8 mg versus 4 mg. METHODS: In double-blind, placebo-controlled, flexible-dose trials, baseline characteristics of OAB patients with >= 1 urgency urinary incontinence (UUI) episodes/24 h who escalated from fesoterodine 4 mg to 8 mg were evaluated. Possible dose-escalation predictors (age; sex; previous antimuscarinic use; UUI, micturitions, and urgency episodes/24 h; race; body mass index; time to dose escalation; OAB duration) were compared in escalators versus non-escalators. Patients from fixed-dose trials with dose-escalator characteristics were identified (matched dose-escalator sample) to assess changes from baseline with fesoterodine 4 mg, 8 mg, and placebo. RESULTS: In flexible dose trials, significant predictors of fesoterodine dose escalation were younger age (<= 65.8 years), greater number of baseline micturitions (>= 13.1) and urgency episodes/24 h (>= 10.9), greater OAB duration (>= 9.1 years), and more frequent previous antimuscarinic use (58.3%), but not baseline UUI episodes/24 h. In the matched dose-escalator sample (fesoterodine 4 mg: n = 215; 8 mg: n = 198; placebo: n = 217), change from baseline in UUI episodes significantly improved with fesoterodine 8 mg versus 4 mg (P = 0.043) and with both doses versus placebo (P < 0.001). Dry mouth and constipation rates were higher with fesoterodine 8 mg. CONCLUSIONS: Dose-escalator patients had a significantly greater UUI response with fesoterodine 8 mg versus 4 mg. Given the potential for adverse events, fesoterodine 4 mg is recommended to start; however, patients with UUI and identified predictors may benefit from initial treatment with fesoterodine 8 mg or rapid dose escalation. PMID- 29600401 TI - Early catheter removal after pelvic floor reconstructive surgery: a randomized trial. AB - INTRODUCTION AND HYPOTHESIS: Studies have yet to examine the impact of day-of surgery voiding trials on post-operative urinary retention in women undergoing obliterative and apical suspension procedures for pelvic organ prolapse. Our objective was to evaluate if time to spontaneous void after these procedures is shorter when a voiding trial is performed on the day of surgery compared with our standard practice of post-operative day 1. METHODS: We conducted a randomized, parallel-arm trial in patients undergoing major pelvic floor reconstructive surgery. Women were randomized 1:1 to an early (4 h post-operatively on the day of surgery) or a standard (6 am on post-operative day 1) retrograde voiding trial. RESULTS: A total of 57 women consented. Mean age and BMI were 65 +/- 11 and 27.9 +/- 4.4. Most women had stage III pelvic organ prolapse (77.2%). Groups had similar baseline characteristics. In the intention-to-treat analysis (n = 57), there was no difference in time to spontaneous void in the early versus standard voiding trial groups (15.9 +/- 3.8 vs 28.4 +/- 3.1 hours, p = 0.081). In the adjusted analysis using mutlivariable linear regression, an early voiding trial decreased the time to spontaneous void (abeta -2.00 h, p = 0.031) when controlling for vaginal packing and stage IV prolapse. In the per-protocol analysis, which excluded 4 patients for crossover, spontaneous void occurred 17 hours faster in the early voiding trial group (14.6 +/- 3.7 vs 31.8 +/- 2.9 hours; p = 0.022). Early voiding trial patients experienced ambulation sooner and more often than the standard group (p = 0.02). CONCLUSIONS: A day-of-surgery voiding trial did not prolong catheter use after obliterative and apical suspension procedures. PMID- 29600402 TI - Bladder management during pregnancy in women with spinal-cord injury: an observational, multicenter study. AB - INTRODUCTION AND HYPOTHESIS: Pregnancy in women with spinal-cord injury (SCI) poses a clinical challenge. We hypothesized that changes in the management of neurogenic bladder during pregnancy are commonly required and should receive more attention. METHODS: Data were collected by retrospective analysis of medical records and via cross-sectional survey of 52 women with SCI, representing 67 pregnancies, at ten Italian neurourological clinics. All participants provided informed consent. RESULTS: Between 1976 and 2013, 39 participants had one child, 11 had two children, and two had three children. Mean age at the time of SCI was 18 years and at the time of first pregnancy was 30 years. Delivery occurred from weeks 32 to 40 in 98% of first and second pregnancies, and 94% of neonates were healthy. Oxybutynin was used by four women during five pregnancies, which resulted in delivery of healthy babies. Intermittent catheterization was used before 54% of first pregnancies and 39% of second pregnancies. Bladder management was altered during 45% of these pregnancies, and the most common changes were increased use or frequency of intermittent catheterization or use of an indwelling catheter. Urinary tract infections occurred in 48% of pregnancies, and an irregular course was reported in 13% of pregnancies mainly related to tetraplegia and urological complications. CONCLUSIONS: Pregnancy in women with SCI generally has good outcomes and limited risks but frequently necessitates changes in the management of neurogenic bladder. High levels of awareness and focused monitoring of bladder issues are recommended. PMID- 29600403 TI - Effect of subsequent vaginal delivery on bowel symptoms and anorectal function in women who sustained a previous obstetric anal sphincter injury. AB - INTRODUCTION AND HYPOTHESIS: Our primary objective was to prospectively evaluate anorectal symptoms, anal manometry and endoanal ultrasound (EAUS) in women who followed the recommended mode of subsequent delivery following index obstetric anal sphincter injuries (OASIs) using our unit's standardised protocol. Our secondary objectives were to evaluate the role of internal anal sphincter defects and also to compare outcomes in a subgroup of symptomatic women with normal anorectal physiology. METHODS: This is a prospective follow-up study of pregnant women with previous OASIs who were counselled regarding subsequent mode of delivery between January 2003 and December 2014. Assessment involved the St Mark's Incontinence Score (SMIS), anal manometry and EAUS at both antepartum and 3-month postpartum visits. Data were analysed using Wilcoxon and Mann-Whitney U tests. RESULTS: Three hundred and fifty women attended the perineal clinic over the study period, of whom 122 met the inclusion criteria (99 vaginal delivery [VD], 23 caesarean section). No significant worsening of anorectal symptoms was observed following subsequent delivery in the VD group (p = 0.896), although a reduced squeeze pressure was observed at 3 months postpartum (p < 0.001). There were no new defects on EAUS in either group. CONCLUSIONS: This study showed no significant worsening of bowel symptoms and sphincter integrity apart from lower squeeze pressures at 3 months postpartum in the VD group when our standardised protocol was used to recommend subsequent mode of delivery. In the absence of a randomised study, use of this protocol can aid clinicians in their decision making. PMID- 29600404 TI - Differential gene expression of extracellular-matrix-related proteins in the vaginal apical compartment of women with pelvic organ prolapse. AB - INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is a multifactorial disorder that impairs the quality of life (QoL) of older women in particular. The purpose of this study was to elucidate the pathogenesis of POP by focusing on the extracellular matrix (ECM). METHODS: Patients were classified into two groups with or without cervical elongation-using the POP quantification system. Specimens were obtained from 29 women with POP during hysterectomy. The expression of fibulin-5, elastin, integrin beta1 (ITGbeta1), lysyl oxidase-like protein-1 (LOXL1) and collagen in the vagina, uterosacral ligament, and uterine cervix was investigated by quantitative real-time polymerase chain reaction (RT PCR) and correlation between gene levels and severity of POP examined. The location of proteins was analyzed using immunohistochemical staining and expression of fibulin-5 protein analyzed by Western blotting. RESULTS: Fibulin-5 and elastin were mainly expressed in lamina propria and fibromuscular layers of the vagina and uterosacral ligament. Gene levels of fibulin-5 and ITGbeta1 in uterosacral ligaments increased with severity of POP in women with cervical elongation, while no correlation was observed in women with a normal cervix. In women with uterine cervical elongation, each ECM-related gene significantly increased with POP staging. Furthermore, fibulin-5 protein also increased in the uterosacral ligament and uterine cervix. CONCLUSIONS: The severity of POP and gene expression of ECM-related proteins were inversely correlated in vaginal tissue in a normal and elongated cervix. These results suggested that the differing progression of the two types of POP have a relationship with ECM related protein. PMID- 29600405 TI - Comparing postoperative voiding dysfunction after mid-urethral sling using either a Babcock or Kelly clamp tensioning technique. AB - INTRODUCTION AND HYPOTHESIS: The objective was to compare postoperative urinary retention using the Babcock and Kelly clamps for retropubic midurethral sling (RPS) tensioning. METHODS: This was a retrospective cohort of isolated RPS procedures from December 2010 through April 2016 by five fellowship-trained surgeons at two institutions. Slings were tensioned with a Babcock clamp by grasping a 3-mm midline fold of mesh (RPS-B) or a Kelly clamp as a spacer between the sling and suburethral tissue (RPS-K). Assessment of urinary retention included the primary outcome of postoperative catheterization and several secondary outcomes, including discharge home with a catheter, within 1 year of surgery. Analysis of covariance was used to compute the mean difference in duration of catheterization and log-binomial regression was used to calculate risk ratios (RR) and 95% confidence intervals (CI). RESULTS: We included 240 patients. The RPS-B group had a lower body mass index and was more likely to be menopausal, have had pelvic organ prolapse surgery, and have a lower maximum urethral closure pressure than the RPS-K group. The mean duration of catheterization was similar, as demonstrated by the crude (0.21 days [-0.30 0.71]) and BMI-adjusted (0.07 days [-0.41-0.55]) mean difference in duration of catheterization. The incidence of postoperative OAB symptoms was comparable between the groups (BMI-adjusted RR: 0.95 (0.80-1.1)), and the incidence of revision did not differ (p = 0.7). CONCLUSIONS: The Babcock and Kelly clamp tensioning techniques appear comparable, with a low incidence of prolonged postoperative catheterization. Most catheters were removed on the day of the surgery. It is reasonable to tension retropubic midurethral slings with either method. PMID- 29600406 TI - [Selective mutism]. AB - Selective mutism was first described in the medical literature 140 years ago. The diagnosis came into the focus of adult psychiatry with the appearance of DSM-5. Henceforth, selective mutism during infancy, adolescence and also adulthood is specified as an independent anxiety disorder. It often begins in early childhood with a kind of speechlessness in certain situations. A diagnostic clarification often only takes place after school enrolment. Very often comorbid anxiety disorders, especially social phobia and depression also occur. The course is very variable and with some affected persons regression of the pathology occurs suddenly and completely and with others there is a slow regression of the symptoms. Equally the disorder can persist until adulthood. Whilst formerly a traumatic genesis was assumed, a multifactorial etiology with genetic, psychological and language-associated effects is nowadays presumed. The therapy is supported through psychotherapy, speech therapy and psychopharmacology.

PMID- 29600408 TI - Independent regulation of renin-angiotensin-aldosterone system in the kidney. AB - Renin-angiotensin-aldosterone system (RAAS) plays important roles in regulating renal hemodynamics and functions, as well as in the pathophysiology of hypertension and renal disease. In the kidney, angiotensin II (Ang II) production is controlled by independent multiple mechanisms. Ang II is compartmentalized in the renal interstitial fluid with much higher concentrations than those existing in the circulation. Inappropriate activation of the intrarenal RAAS is an important contributor to the pathogenesis of hypertension and renal injury. It has been revealed that intrarenal Ang II levels are predominantly regulated by angiotensinogen and therefore, urinary angiotensinogen could be a biomarker for intrarenal Ang II generation. In addition, recent studies have demonstrated that aldosterone contributes to the progression of renal injury via direct actions on glomerular podocytes, mesangial cells, proximal tubular cells and tubulo interstitial fibroblasts through the activation of locally expressed mineralocorticoid receptor. Thus, it now appears that intrarenal RAAS is independently regulated and its inappropriate activation contributes to the pathogenesis of the development of hypertension and renal disease. This short review article will focus on the independent regulation of the intrarenal RAAS with an emphasis on the specific role of angiotensinogen. PMID- 29600409 TI - Alcohol consumption and incidence of proteinuria: a retrospective cohort study. AB - BACKGROUND: Previous studies report conflicting results of a dose-dependent association between alcohol consumption and incidence of chronic kidney disease. Only a few studies have assessed the clinical impact of > 45-65 g/day of critically high alcohol consumption. METHODS: This retrospective cohort study included 88,647 males and 88,925 females with dipstick urinary protein <= +/- and estimated glomerular filtration rate >= 60 mL/min/1.73 m2 at their first annual health examinations between April 2008 and March 2010 in Japan. The exposure was the self-reported alcohol consumption. The outcome was proteinuria defined as dipstick urinary protein >= 1 + or >= 2 +. RESULTS: During median 1.8 years (interquartile range 1.0-2.1) of the observational period, 5416 (6.1%) males and 3262 (3.7%) females developed proteinuria defined as dipstick urinary protein >= 1 +. In males, a U-shape association between alcohol consumption and proteinuria was observed in a multivariable-adjusted Poisson regression model [incidence rate ratio (95% confidence interval) of rare, occasional, and daily drinkers with <= 19, 20-39, 40-59, and >= 60 g/day: 1.00 (reference), 0.86 (0.79-0.94), 0.70 (0.64 0.78), 0.82 (0.75-0.90), 1.00 (0.90-1.11), and 1.00 (0.85-1.17), respectively], whereas a J-shape association was observed in females [1.00 (reference), 0.81 (0.75-0.87), 0.74 (0.64-0.85), 0.93 (0.78-1.11), 1.09 (0.83-1.44), and 1.45 (1.02 2.08), respectively]. Similar associations with dipstick urinary protein >= 2 + were shown in males and females. CONCLUSIONS: Moderate alcohol consumption was associated with lower risk of proteinuria in both males and females. Females with >= 60 g/day of high alcohol consumption were at higher risk of proteinuria, whereas males were not. Females were more vulnerable to high alcohol consumption, than males. PMID- 29600410 TI - Butyrylcholinesterase level as an independent factor of erythropoiesis stimulating agent resistance in patients on maintenance hemodialysis: a single center cross-sectional study. AB - BACKGROUND: Erythropoiesis-stimulating agent (ESA) responsiveness is related to the nutritional status of patients on hemodialysis (HD). Serum butyrylcholinesterase (BChE), an alpha-glycoprotein, may decrease in case of malnutrition. We investigated whether BChE was independently related to ESA resistance in patients on HD. METHODS: The laboratory data and ESA resistance index (ERI), defined as ESA dosage per week divided by dry weight and hemoglobin, were investigated in 215 patients on HD between July and September 2017. Malnutrition was defined as Geriatric Nutritional Risk Index (GNRI) of < 91.2. The patients were stratified into two groups: ERI-high (ERI >= 9.44) and ERI-low (ERI < 9.44) groups. Variables such as patient's background, medication, and laboratory data were compared between the two groups. The optimal cutoff value of BChE for higher ERI was determined using receiver operating characteristic analysis. Factors independently associated with higher ERI were determined using multivariate logistic regression analysis. RESULTS: The median and optimal cutoff values of ERI and BChE were 6.51 and 200 IU/L, respectively. The study included 71 (33%) and 144 (67%) patients in the ERI-high and ERI-low groups, respectively. Significant between-group differences were observed concerning age, hemoglobin, ESA dose, lipid profiles, serum albumin, body mass index, GNRI, iron metabolism markers, ferric medicines, and BChE. Multivariate analysis showed that BChE < 200 IU/L (odds ratio 3.67; 95% confidence interval 1.73-7.77) continued to be an independent factor associated with higher ERI after adjusting for potential confounders, which was a similar odds ratio as GNRI < 91.2. CONCLUSION: BChE may be an independent indicator of ESA resistance. PMID- 29600411 TI - Differential Modulation of Endophytic Microbiome of Ginger in the Presence of Beneficial Organisms, Pathogens and Both as Identified by DGGE Analysis. AB - Endophytic microorganisms play a significant role in plants response to beneficial organisms and pathogens. In the current study, endophytic microorganisms from Zingiber officinale were screened for in vitro inhibition against Pythium myriotylum. From this, Burkholderia vietnamiensis ZoB74 was selected as an organism with remarkable antifungal effect. Further, the study focussed on analysis of in vivo changes in endophytic bacterial community of Z. officinale in presence of selected organisms and the pathogen P. myriotylum by PCR-DGGE. 16S rDNA sequencing of bacterial community after DGGE has resulted in the identification of a group of uncultured bacteria as the predominant microbial community of rhizome under various conditions of treatment. High frequency dominance of these endophytic bacteria suggests their role in disease resistance to soft rot in ginger. This also revealed the variation of endophytic microbiome of Z. officinale under biotic stress. Hence the study provides molecular insight into uncultured microbiome and its stress-inducible variation in ginger rhizome. PMID- 29600412 TI - Associations of monoamine oxidase A gene first exon methylation with sexual abuse and current depression in women. AB - Childhood physical abuse (PA) and sexual abuse (SA) interact with monoamine oxidase A (MAOA) gene polymorphism to modify risk for mental disorders. In addition, PA and SA may alter gene activity through epigenetic mechanisms such as DNA methylation, thereby further modifying risk for disorders. We investigated whether methylation in a region spanning the MAOA first exon and part of the first intron was associated with PA and/or SA, MAOA genotype, alcohol dependence, drug dependence, depression disorders, anxiety disorders, and conduct disorder. 114 Swedish women completed standardized diagnostic interviews and questionnaires to report PA and SA, and provided saliva samples for DNA extraction. DNA was genotyped for MAOA-uVNTR polymorphisms, and methylation of a MAOA region of interest (chrX: 43,515,544-43,515,991) was measured. SA, not PA, was associated with hypermethylation of the MAOA first exon relative to no-abuse, and the association was robust to adjustment for psychoactive medication, alcohol and drug dependence, and current substance use. SA and MAOA-uVNTR genotype, but not their interaction, was associated with MAOA methylation. SA associated with all measured mental disorders. Hypermethylation of MAOA first exon mediated the association of SA with current depression, and both methylation levels and SA independently predicted lifetime depression. Much remains to be learned about the independent effects of SA and MAOA-uVNTR genotypes on methylation of the MAOA first exon. PMID- 29600413 TI - Palliative sedation in advanced cancer patients hospitalized in a specialized palliative care unit. AB - PURPOSE: To describe the practice of palliative sedation (PS) in patients with advanced cancer in a specialized palliative care (PC) unit in Colombia. METHODS: Descriptive prospective study including all adults with cancer hospitalized under PS in a cancer institute between January and July 2015 in Colombia. Variables examined were diagnosis, physical functioning, symptoms at the start of sedation, medications and dosages used, and type, level, and time of sedation. Descriptive and correlational statistics were obtained. RESULTS: Sixty-six patients were included, 70% of which were women. The patients had an average age of 61 years (range 24-87), and 74% had a Karnofsky Index (KI) of 50% or less. The most frequent diagnosis was breast cancer (22%), and 82% had metastatic cancer. The prevalence of palliative sedation was 2% and the most common symptoms indicating it were dyspnea (59%), delirium (45%), and pain (32%). All patients received midazolam as a sedative. The average time between the interval start and culmination of sedation was 44 h. There was a significant and inverse relationship between functionality and time under sedation. CONCLUSIONS: Palliative sedation is a valid therapeutic option for refractory symptoms causing suffering. The results correspond to international reports and guidelines, which suggests that PS is tailored to the needs of the individual patient while maintaining a high scientific standard, even in a context where PC is under development. However, further development of strategies and clear indications towards the use of PS in Colombia are needed, given its still scarce use. PMID- 29600415 TI - The cultural expression of spiritual distress in Israel. AB - BACKGROUND: Although spiritual distress is present across cultures, the ways in which patients experience it vary between cultures. Our goal was to examine the cultural expression and key indicators of spiritual distress in Israel. METHODS: We conducted a structured interview of 202 oncology outpatients in a cross sectional study. Self-diagnosis of spiritual distress, which is a demonstrated gold standard for identifying its presence, was compared with the Facit-Sp-12 and a number of other items (from the Spiritual Injury Scale and newly developed Israeli items) hypothesized as Israeli cultural expressions of spiritual distress, demographic and medical data, and patient desire to receive spiritual care. RESULTS: Significant variation was found between Israeli cultural expression of spiritual distress and that found in studies from other countries. Key expressions of spiritual distress in this study included lack of inner peace, grief, and an inability to accept what is happening. Items related to faith were not significant, and loss of meaning showed mixed results. Patients requesting spiritual care were more likely to be in spiritual distress. No demographic or medical data correlated with spiritual distress. CONCLUSIONS: Specially designed interventions to reduce spiritual distress should address the expressions of the distress specific to that culture. Studies of the efficacy of spiritual care can examine the extent of spiritual distress in general or of its specific cultural expressions.

AB - PURPOSE: Metastatic epidural spinal cord compression (MESCC) is radiologically defined as an epidural metastatic lesion causing the displacement of the spinal cord from its normal position in the vertebral canal. The purpose of this paper is the evaluation of the influence of timing of surgery on the chance of neurological recovery. METHODS: This is a retrospective observational case control study performed on patients with MESCC from solid tumors surgically treated at our institute from January 2010 to December 2016. Patients included were divided in two groups depending on surgery that was performed within or after 24 h the admission to the hospital. Neurological status was assessed with American Spine Injury Association (ASIA) Impairment Scale. RESULTS: No statistically significant difference was observed in the variation of ASIA if surgery is performed within or after 24 h from the admission to the hospital. A statistically significant difference was observed after surgery in each group in the improvement of neurological status. A statistically significant difference was reported in the early post-operative complications in patients surgically treated within 24 h. CONCLUSION: MESCC management is challenge for spine surgeons and may represent an oncologic emergency and if not promptly diagnosed can lead to a permanent neurological damage. According to this study, there is no difference in the chance of neurological recovery if surgery is performed within or after 24 h the admission to hospital, but there is a greater rate of early post-operative complications when surgery is performed within 24 h from the admission to the hospital.

PMID- 29600418 TI - Comparison of Model Averaging and Model Selection in Dose Finding Trials Analyzed by Nonlinear Mixed Effect Models. AB - In drug development, pharmacometric approaches consist in identifying via a model selection (MS) process the model structure that best describes the data. However, making predictions using a selected model ignores model structure uncertainty, which could impair predictive performance. To overcome this drawback, model averaging (MA) takes into account the uncertainty across a set of candidate models by weighting them as a function of an information criterion. Our primary objective was to use clinical trial simulations (CTSs) to compare model selection (MS) with model averaging (MA) in dose finding clinical trials, based on the AIC information criterion. A secondary aim of this analysis was to challenge the use of AIC by comparing MA and MS using five different information criteria. CTSs were based on a nonlinear mixed effect model characterizing the time course of visual acuity in wet age-related macular degeneration patients. Predictive performances of the modeling approaches were evaluated using three performance criteria focused on the main objectives of a phase II clinical trial. In this framework, MA adequately described the data and showed better predictive performance than MS, increasing the likelihood of accurately characterizing the dose-response relationship and defining the minimum effective dose. Moreover, regardless of the modeling approach, AIC was associated with the best predictive performances.

AB - The cross-sectional study of heavy metals and aflatoxins was conducted by studying duck egg, blood, liver, feed, and water samples from 11 free grazing farms. The duck feed, soil, and rice samples were lower than the standard limit for aflatoxins at 20 ng g-1. The highest levels of aflatoxin were detected in the liver, intestine, and egg yolk; these were 3.04, 1.73, and 4.56 ng g-1 respectively, while the average levels were 1.6 +/- 0.73, 1.31 +/- 0.23, and 1.87 +/- 0.99 ng g-1, respectively. Interestingly, aflatoxin was not detected in any of the egg white albumin samples (90/90 samples), whereas aflatoxin contamination was predominantly found in the yolk. Additionally, the means and standard deviations of Pb and Cd found in the duck eggs were 118.61 +/- 22.25 and 13.84 +/ 9.06 ng g-1 respectively. The maximum levels of Pb and Cd in eggs were 134.34 and 29.72 ng g-1, respectively. Moreover, Pb contamination occurred in the duck liver tissue in 93.61% (88/94) of the samples, whereas Cd contamination was found in 100% (100/100). The maximum levels of Pb and Cd in the duck liver tissues were 606.16 and 22,946.20 ng g-1, which was higher than those in the eggs. Pb contamination in the water from rice paddy fields after grazing was significantly higher than that in water samples taken before grazing. This is the first report of Pb and Cd contamination in blood, egg, and liver samples of free grazing ducks in Thailand.

AB - AlphaBSTRACT: We report the first case of robot-assisted partial nephrectomy (RARN) and Robot assisted cholecystectomy in a 66 years old female overweight patient with organ-confined right kidney tumor identified on the investigation of gastrointestinal symptoms with a single docking. A modified position of the patient and a slight altered placement of the trocars made feasible the concomitant performance of the two operations. Total blood loss was 80 ml, operation time was 253 min and console time 187 min. The drain was removed on second post-operative day and the patient was discharged at the 3rd post operative day. Using a single docking of the da Vinci S system, intraoperative time and cost are minimized in patients with both organ-confined kidney tumors and gall bladder stones.

AB - Venous malformations are the most common of all vascular anomalies. Venous malformations are treated using a multidisciplinary approach with sclerotherapy representing the primary treatment modality. While rare, sclerotherapy in the central nervous system carries the risk of venous thrombosis, non-target embolization, and venous infarction and hemorrhage. Options for controlling venous outflow when treating venous malformations in the head and neck are limited. This report details the use of balloon and coil occlusion of a superior sagittal sinus cortical vein to facilitate percutaneous sclerotherapy of a supraorbital venous malformation. PMID- 29600423 TI - Travel Time to Clinic but not Neighborhood Crime Rate is Associated with Retention in Care Among HIV-Positive Patients. AB - Using geospatial analysis, we examined the relationship of distance between a patient's residence and clinic, travel time to clinic, and neighborhood violent crime rates with retention in care or viral suppression among people living with HIV (PLWH). For HIV-positive patients at a large urban clinic, we measured distance and travel time between home and clinic and violent crime rate within a two block radius of the travel route. Kruskal-Wallis rank sum was used to compare outcomes between groups. Over the observation period, 2008-2016, 219/602 (36%) patients were retained in care. Median distance from clinic was 3.6 (IQR 2.1-5.6) miles versus 3.9 (IQR 2.7-6.1) miles among those retained versus not retained in care, p = 0.06. Median travel time by car was 15.9 (IQR 9.6-22.9) versus 17.1 (IQR 12.0-24.6) minutes for those retained versus not retained, p = 0.04. Violent crime rate along travel route was not associated with retention. There was no significant association between travel time or distance and viral suppression. PMID- 29600424 TI - Comparison of Ice Hockey Goaltender Helmets for Concussion Type Impacts. AB - Concussions are among the most common injuries sustained by ice hockey goaltenders and can result from collisions, falls and puck impacts. However, ice hockey goaltender helmet certification standards solely involve drop tests to a rigid surface. This study examined how the design characteristics of different ice hockey goaltender helmets affect head kinematics and brain strain for the three most common impact events associated with concussion for goaltenders. A NOCSAE headform was impacted under conditions representing falls, puck impacts and shoulder collisions while wearing three different types of ice hockey goaltender helmet models. Resulting linear and rotational acceleration as well as maximum principal strain were measured for each impact condition. The results indicate that a thick liner and stiff shell material are desirable design characteristics for falls and puck impacts to reduce head kinematic and brain tissue responses. However for collisions, the shoulder being more compliant than the materials of the helmet causes insufficient compression of the helmet materials and minimizing any potential performance differences. This suggests that current ice hockey goaltender helmets can be optimized for protection against falls and puck impacts. However, given collisions are the leading cause of concussion for ice hockey goaltenders and the tested helmets provided little to no protection, a clear opportunity exists to design new goaltender helmets which can better protect ice hockey goaltenders from collisions. PMID- 29600425 TI - A novel bispecific antibody fusion protein co-targeting EGFR and CD47 with enhanced therapeutic index. AB - OBJECTIVE: To promote targeting specificity of anti-CD47 agents, we have constructed a novel bispecific antibody fusion protein against EGFR and CD47, which may minimize the "off-target" effects caused by CD47 expression on red blood cells. RESULTS: The novel bispecific antibody fusion protein, denoted as Bi SP could simultaneously bind to EGFR and CD47 and exhibited potent phagocytosis stimulation effects in vitro. Bi-SP treatment with a low dose more effectively inhibited tumor growth than either EGFR-targeting antibody, Pan or the SIRPalpha variant-Fc (SIRPalphaV-Fc) in the A431 xenograft tumor model. In addition, the treatment with Bi-SP produced less red blood cell (RBC) losses than the SIRPalphaV-Fc treatment, suggesting its potential use for minimizing RBC toxicity in therapy. CONCLUSIONS: Bi-SP with improved therapeutic index has the potential to treat CD47+ and EGFR+ cancers in clinics. PMID- 29600426 TI - Antibiotic-induced fever in orthopaedic patients-a diagnostic challenge. AB - INTRODUCTION: Antibiotic-induced fever is a probably underestimated complication, which may be misdiagnosed as new infection. In this study, characteristics, diagnostic approach, and outcome of antibiotic-induced fever in patients treated for musculoskeletal infections are described. METHODS: We retrospectively reviewed all patients with antibiotic-induced fever after surgery treated at our institution from 2014 to 2017. Antibiotic-induced fever was diagnosed, if the following criteria were fulfilled: (i) central (ear) body temperature > 38.0 degrees C; (ii) intravenous antibiotics for > three days; (iii) exclusion of infectious or other non-infectious causes of fever; and (iv) defervescence after discontinuation of antibiotics. RESULTS: We included 11 patients (median age 51 years) treated for infection after fracture fixation (n = 5), periprosthetic joint infections (n = 3), infection after spinal instrumentation (n = 1), and soft tissue infection (n = 2). The suspected antibiotics inducing fever were beta lactam antibiotics (n = 9), vancomycin (n = 3), daptomycin (n = 2), clindamycin, and meropenem (n = 1 each). Additional clinical findings were reduced general condition, generalized exanthema, and rigors, whereas five patients were asymptomatic apart from a fever. Leukopenia was observed in nine patients and increase of C-reactive protein value in ten patients. Fever occurred after a median of 20 days of antibiotic treatment and resolved after a median of one day after discontinuation of the suspected antibiotic. CONCLUSIONS: Antibiotics should be considered as the possible cause of fever in orthopaedic patients receiving antimicrobial treament whenever clinical signs of new or persisting infection are lacking. Important hints suggestive for antibiotic-induced fever are good general condition despite high temperature and progressive leukopenia. Discontinuation or change to another substance leads to prompt defervescence, preventing unnecessary diagnostic procedures and antibiotic treatment. PMID- 29600427 TI - PAS positivity of erythroid precursor cells is associated with a poor prognosis in newly diagnosed myelodysplastic syndrome patients. AB - Myelodysplastic syndrome (MDS) is a group of clonal stem cell disorders characterized by hematopoietic insufficiency. The accurate risk stratification of patients with MDS is essential for selection of appropriate therapies. We herein conducted a retrospective cohort study to examine the prognostic value of periodic acid-Schiff (PAS) reaction-positive erythroblasts in MDS patients. We examined the PAS positivity of the bone marrow erythroblasts of 144 patients newly diagnosed with MDS; 26 (18.1%) of them had PAS-positive erythroblasts, whereas 118 (81.9%) did not. The PAS-positive group showed significantly poorer karyotypes as defined in the revised International Prognostic Scoring System (IPSS-R) and higher scores in age-adjusted IPSS-R (IPSS-RA) than the PAS-negative group. Overall survival (OS) and leukemia-free survival (LFS) were also significantly shorter in the PAS-positive group than in the PAS-negative group. Similar results were obtained when only high- and very high risk groups were analyzed using IPSS-RA. This retrospective study suggested that the PAS positivity of erythroblasts is an additional prognostic factor combined with other risk scores for OS and LFS in MDS, and our results may contribute to improved clinical decision-making and rapid risk stratification. PMID- 29600428 TI - CBL mutation and MEFV single-nucleotide variant are important genetic predictors of tumor reduction in glucocorticoid-treated patients with chronic myelomonocytic leukemia. AB - Glucocorticoid (GC) therapy occasionally relieves tumor-related fever and promotes tumor reduction in patients with chronic myelomonocytic leukemia (CMML). A mutation analysis of 24 patients with CMML revealed the relationship of GC effectiveness, defined as a monocyte reduction of > 50% within 3 days of methylprednisolone administration, with the MEFV single-nucleotide variant (SNV) and CBL mutation. Lipopolysaccharide-stimulated monocytes harboring MEFV E148Q produced greater amounts of IL-1beta and TNF-alpha than did wild-type monocytes; this was effectively suppressed by GC. Primary CMML cells harboring the MEFV SNV and CBL mutation, and the myelomonocytic leukemia cell line GDM-1, harboring the CBL mutation, were both more significantly suppressed than non-mutated cells following GC treatment in the presence of GM-CSF. A loss-of-function CBL mutation prolonged STAT5 phosphorylation after GM-CSF stimulation, which was rapidly terminated in both patient samples and GDM-1 cells. In conclusion, GC therapy effectively treats CMML cells harboring the MEFV SNV and CBL mutation by reducing inflammatory cytokine production and terminating prolonged STAT5 phosphorylation in the GM-CSF signaling pathway. PMID- 29600429 TI - Efficacy and safety of ledipasvir/sofosbuvir for genotype 1b chronic hepatitis C patients with moderate renal impairment. AB - BACKGROUND/AIM: To evaluate the efficacy and safety of ledipasvir and sofosbuvir therapy for genotype 1b in chronic hepatitis C patients with chronic kidney disease (CKD) stage 3. METHODS: In a multicenter collaborative retrospective study, 706 patients who have received ledipasvir which is NS5A inhibitor, and sofosbuvir 400 mg which is NS5B nucleoside polymerase inhibitor daily for 12 weeks between September 2015 and January 2017 were subjected to this analysis. Virologic response and adverse events in patients with CKD stage 3 were compared with those in patients with CKD stages 1 and 2. RESULTS: The rates of sustained virologic response (SVR) were 97.0% in patients with CKD stage 1, 97.1% in patients with CKD stage 2, and 94.7% in patients with CKD stage 3, respectively. There were no significant differences in the SVR rates between CKD stages 1 and 2, and CKD stage 1 and stage 3. The incidence of adverse events over than grade 2 was 0% in patients with CKD stage 1, 0.5% in patients with CKD stage 2, and 3.0% in patients with CKD stage 3, respectively. For treatment and follow-up period, eGFR levels in the patients with CKD stage 3 were not worsened compared to those at baseline. CONCLUSION: This study suggested that the virologic response of ledipasvir and sofosbuvir in patients with CKD stage 3 was not inferior to those with CKD stages 1 and 2. In addition, administration of ledipasvir and sofosbuvir did not affect eGFR levels in the patients with CKD stage 3. PMID- 29600430 TI - Targeting incretin hormones and the ASK-1 pathway as therapeutic options in the treatment of non-alcoholic steatohepatitis. AB - Non-alcoholic fatty liver disease (NAFLD) is currently one of the leading forms of chronic liver disease, and its rising frequency worldwide has reached epidemic proportions. NAFLD, particularly its progressive variant NASH (non-alcoholic steatohepatitis), can lead to advanced fibrosis, cirrhosis, and HCC. The pathophysiologic mechanisms that contribute to the development and progression of NAFLD and NASH are complex, and as such myriad therapies are under investigation targeting different pathophysiological mechanisms. Incretin-based therapies, including GLP-1RAs and DPP-4 inhibitors and the inhibition of ASK1 pathway have provided two such novel mechanisms in the management of this disease, and will remain focus of this review. PMID- 29600432 TI - Catheter probe extraductal ultrasound (EDUS) exploration of the common bile duct is safe in elderly patients with suspicion of choledocholithiasis after distal gastrectomy. AB - PURPOSE: Post-surgical upper gastrointestinal anatomy may hamper a complete bilio pancreatic evaluation with a standard echoendoscope. The aim of this study was to assess the role of catheter probe extraductal ultrasound (EDUS) for the evaluation of the common bile duct (CBD) in patients who are status post-gastric surgery and who are suspected of having choledocholithiasis. METHODS: We retrospectively analyzed patients with a prior history of gastric surgery, who underwent EDUS for a suspicion of CBD obstruction. For each patient, technical success, accuracy, and safety were recorded. In case of a positive finding of CBD stones, endoscopic retrograde cholangiopancreatography (ERCP) was performed. In case of other findings or a negative EDUS, computed tomography or magnetic resonance cholangiopancreatography (MRCP) was performed as appropriate. RESULTS: EDUS was technically successful in all the 11 patients with a Billroth II gastrectomy, while it failed in all the 5 patients with Roux-en-Y gastric surgery. EDUS accuracy was 100% (3 true-positive and 8 true-negative cases). CBD stones, confirmed and successfully extracted at ERCP, were found in two patients, while in one patient EDUS showed a CBD stenosis that was treated with a plastic stent during ERCP; computed tomography at follow-up was negative for cancer. EDUS was correctly negative in 8 patients, as confirmed by MRCP. CONCLUSIONS: EDUS may represent an accurate and safe alternative to standard endoscopic ultrasonography and MRCP for the detection of CBD stones in elderly patients who are status post Billroth II gastric surgery. PMID- 29600431 TI - Effectiveness of arginase inhibitors against experimentally induced stroke. AB - Stroke is a lethal disease, but it disables more than it kills. Stroke is the second leading cause of death and the most frequent cause of permanent disability in adults worldwide, with 90% of survivors having residual deficits. The pathophysiology of stroke is complex and involves a strong inflammatory response associated with oxidative stress and activation of several proteolytic enzymes. The current study was designed to investigate the effect of arginase inhibitors (L-citruline and L-ornithine) against ischemic stroke induced in rats by middle cerebral artery occlusion (MCAO). MCAO resulted in alteration in rat behavior, brain infarct, and edema associated with disruption of the blood-brain barrier (BBB). This was mediated through overexpression of arginase I and II, inducible NOS (iNOS), malondialdehyde (MDA), advanced glycation end products (AGEs), TNF alpha, and IL-1beta and downregulation of endothelial nitric oxide synthase (eNOS). Treatment with L-citruline and L-ornithine and the standard neuroprotective drug cerebrolysin ameliorated all the deleterious effects of stroke. These results indicate the possible use of arginase inhibitors in the treatment of stroke after suitable clinical trials are done. PMID- 29600434 TI - Environmental Behavior Among Russian Youth: The Role of Self-direction and Environmental Concern. AB - Previous research that has tried to identify the personal values that best explain variance in pro-environmental attitudes tended to focus on biospheric and universalism values. This paper examines the importance of self-direction as a value underlying young people's inclination to adopt pro-environmental behaviors and environmental activism. We expect that individuals who emphasize a self direction value, which fosters creativity, motivates innovation, and promotes coping with challenges, are likely to respond in more self-directed and autonomous ways to emerging environmental practices. We analyze a sample of 600 university students surveyed in Moscow and find that biospheric and self direction values are associated with environmental behavior and activism. Beyond the direct effect of self-direction value on pro-environmental behaviors and environmental activism we also observe a moderation effect of self-direction on the association between concern and environmental behavior. We discuss the implications of our findings for encouraging environmental action in specific contexts, similar to the one depicted in our sample. PMID- 29600433 TI - Estrogen therapy in patients with prostate cancer: a contemporary systematic review. AB - PURPOSE: To evaluate the effectiveness and harms of DES in treating prostate cancer compared to other forms of androgen deprivation therapy (orchiectomy, LHRH agonists, and anti-androgens). METHODS: We included clinical trials comparing DES with other forms of ADT (bicalutamide, flutamide, LHRH agonists, or orchiectomy) in PCa treatment. The primary outcomes were overall survival, cancer-specific survival, and progression-free survival, and secondary outcomes were cardiovascular effects. We searched in MEDLINE, EMBASE, Central, and Lilacs from inception to nowadays and saturated information for unpublished data in other sources. We performed a qualitative analysis of all included studies. It was not possible to perform meta-analysis due to low-quality trials and high heterogeneity. RESULTS: Overall, 1700 references were scanned and 14 prospective randomized trials with a total of 3986 patients were included in the final analysis. Although trials showed DES as similarly effective to another forms of ADT, evidences about cardiovascular toxicity in out of date high doses have discouraged its use. In doses of 1 mg, DES has been used as secondary line PCa treatment with safety. CONCLUSIONS: DES might be similarly effective to other forms of ADT on advanced PCa patients, with potential important roles. Intriguingly, the burden of severe cardiovascular toxicity is mainly related to old-fashioned doses of 5.0 and 3.0 mg. Modern PCa hormonal knowledge warrants stout high-quality prospective randomized trials in the low-dose 1 mg DES scenario. PMID- 29600435 TI - Putting Climate Adaptation on the Map: Developing Spatial Management Strategies for Whitebark Pine in the Greater Yellowstone Ecosystem. AB - Natural resource managers face the need to develop strategies to adapt to projected future climates. Few existing climate adaptation frameworks prescribe where to place management actions to be most effective under anticipated future climate conditions. We developed an approach to spatially allocate climate adaptation actions and applied the method to whitebark pine (WBP; Pinus albicaulis) in the Greater Yellowstone Ecosystem (GYE). WBP is expected to be vulnerable to climate-mediated shifts in suitable habitat, pests, pathogens, and fire. We spatially prioritized management actions aimed at mitigating climate impacts to WBP under two management strategies: (1) current management and (2) climate-informed management. The current strategy reflected management actions permissible under existing policy and access constraints. Our goal was to understand how consideration of climate might alter the placement of management actions, so the climate-informed strategies did not include these constraints. The spatial distribution of actions differed among the current and climate informed management strategies, with 33-60% more wilderness area prioritized for action under climate-informed management. High priority areas for implementing management actions include the 1-8% of the GYE where current and climate-informed management agreed, since this is where actions are most likely to be successful in the long-term and where current management permits implementation. Areas where climate-informed strategies agreed with one another but not with current management (6-22% of the GYE) are potential locations for experimental testing of management actions. Our method for spatial climate adaptation planning is applicable to any species for which information regarding climate vulnerability and climate-mediated risk factors is available. PMID- 29600436 TI - Amino acid adsorption on anatase (101) surface at vacuum and aqueous solution: a density functional study. AB - The adsorption of 20 amino acids (AAs) on the (101) surface of anatase titanium dioxide (TiO2) has been investigated under the scheme of density functional theory. Through the analysis of adsorption geometries, amino group and side chains of AAs have been identified as the major side to adsorb on TiO2, while the carboxyl group prefers to stay outside to avoid the repulsion between negatively charged oxygen from TiO2 and AAs. On the surface, two-coordinated oxygen is the major site to stabilize AAs through O-H interactions. The above conclusion does not change when it is in the aqueous solution based on the calculations with AAs surrounded by explicit water molecules. The above knowledge is helpful in predicting how AAs and even peptides adsorb on inorganic materials. Graphical abstract The adsorption of 20 amino acids (AAs) on the (101) surface of anatase titanium dioxide (TiO2) has been investigated under the scheme of density functional theory. PMID- 29600437 TI - CBS mutations and MTFHR SNPs causative of hyperhomocysteinemia in Pakistani children. AB - Three index patients with hyperhomocysteinemia and ocular anomalies were screened for cystathionine beta synthase (CBS) and methylenetetrahydrofolate reductase (MTHFR) polymorphisms. Genotyping of hyperhomocysteinemia associated MTHFR polymorphisms C677T (rs1801133) and A1298C (rs1801131) was done by PCR restriction fragment length polymorphism. Sanger sequencing was performed for CBS exonic sequences along with consensus splice sites. In the case of MTHFR polymorphisms, all the patients were heterozygous CT for the single nucleotide polymorphism (SNP) C677T and were therefore carriers of the risk allele (T), while the patients were homozygous CC for the risk genotype of the SNP A1298C. CBS sequencing resulted in the identification of two novel mutations, a missense change (c.467T>C; p.Leu156Pro) in exon 7 and an in-frame deletion (c.808_810del; p.Glu270del) in exon 10. In addition, a recurrent missense mutation (c.770C>T; p.Thr257Met) in exon 10 of the gene was also identified. The mutations were present homozygously in the patients and were inherited from the carrier parents. This is the first report from Pakistan where novel as well as recurrent CBS mutations causing hyperhomocysteinemia and lens dislocation in three patients from different families are being reported with the predicted effect of the risk allele of the MTHFR SNP in causing hyperhomocysteinemia. PMID- 29600438 TI - Functionalization of PLGA Nanoparticles with 1,3-beta-glucan Enhances the Intracellular Pharmacokinetics of Rifampicin in Macrophages. AB - PURPOSE: Mycobacterium tuberculosis which causes tuberculosis, is primarily resident within macrophages. 1,3-beta-glucan has been proposed as a ligand to target drug loaded nanoparticles (NPs) to macrophages. In this study we characterized the intracellular pharmacokinetics of the anti-tubercular drug rifampicin delivered by 1,3-beta-glucan functionalized PLGA NPs (Glu-PLGA). We hypothesized that Glu-PLGA NPs would be taken up at a faster rate than PLGA NPs, and consequently deliver higher amounts of rifampicin into the macrophages. METHODS: Carbodiimide chemistry was employed to conjugate 1,3-beta-glucan and rhodamine to PLGA. Rifampicin loaded PLGA and Glu-PLGA NPs as well as rhodamine functionalized PLGA and Glu-PLGA NPs were synthesized using an emulsion solvent evaporation technique. Intracellular pharmacokinetics of rifampicin and NPs were evaluated in THP-1 derived macrophages. A pharmacokinetic model was developed to describe uptake, and modelling was performed using ADAPT 5 software. RESULTS: The NPs increased the rate of uptake of rifampicin by a factor of 17 and 62 in case of PLGA and Glu-PLGA, respectively. Expulsion of NPs from the macrophages was also observed, which was 3 fold greater for Glu-PLGA NPs than for PLGA NPs. However, the ratio of uptake to expulsion was similar for both NPs. After 24 h, the amount of rifampicin delivered by the PLGA and Glu-PLGA NPs was similar. The NPs resulted in at least a 10-fold increase in the uptake of rifampicin. CONCLUSIONS: Functionalization of PLGA NPs with 1,3-beta-glucan resulted in faster uptake of rifampicin into macrophages. These NPs may be useful to achieve rapid intracellular eradication of Mycobacterium tuberculosis. PMID- 29600439 TI - Assessment of dietary calcium intake of university students: a pilot study in Turkey. AB - : The aim of this study was to adapt the rapid assessment method (RAM) and International Osteoporosis Foundation Food Frequency Questionnaire (IOF FFQ) tools, used for the assessment of daily calcium intake in university students, and to compare the data obtained using 24-h recall (24-HR) data. There was a moderate positive correlation between the RAM and IOF. PURPOSE/INTRODUCTION: Calcium is an essential mineral that plays vital roles in metabolism and it is very important to accurately assess the amount of calcium intake on the diet. It was aimed to assess the daily calcium intake of university students by two different food frequency questionnaires (FFQs) developed specifically for evaluating calcium intake, and 24-h recall method. METHOD: The study was conducted with a total of 183 female university students aged 18-31. In the study, a questionnaire including sociodemographic information, a calcium calculator, IOF FFQ, prepared in seven different languages, and RAM was applied. In addition, 1-day food consumption records were obtained using 24-HR method. RESULTS: The daily average calcium intakes of individuals according to two different food frequency questionnaires (RAM FFQ and IOF FFQ) and 24-h food consumption records are respectively 1594.2 +/- 810.9, 897.9 +/- 368.4, and 605.6 +/- 278.3 mg. When the daily average calcium intake was compared with the other two methods, RAM was found to be statistically higher (p < 0.001). There was a moderate positive correlation between the RAM and IOF FFQ methods (Pearson r = 0.528, p < 0.01) and the intra-class correlation coefficient between these two methods was found to be significant and moderate (ICC r = 0.452, p < 0.01). CONCLUSION: In terms of protecting and improving health, it is important to make suggestions using fast and short tools to ensure adequate calcium intake from young age. It is thought that FFQs are the most appropriate methods in assessing daily calcium intake for this study group because it is observed that the list of foods and the amount of portions in FFQs reduce the problem of remembering at 24 h method to a great extent.

AB - Because natural ecosystems and ecosystem services (ES) are both critical to the well-being of humankind, it is important to understand their relationships and congruence for conservation planning. Spatial conservation planning is required to set focused preservation priorities and to assess future ecological implications. This study uses the combined measures of ES models and ES potential to estimate and analyze all four groups of ecosystem services to generate opportunities to maximize ecosystem services. Subsequently, we identify the key areas of conservation priorities as future forestation and conservation hotspot zones to improve the ecological management in Chongqing City, located in the upper reaches of the Three Gorges Reservoir Area, China. Results show that ecosystem services potential is extremely obvious. Compared to ecosystem services from 2000, we determined that soil conservation could be increased by 59.11%, carbon sequestration by 129.51%, water flow regulation by 83.42%, and water purification by 84.42%. According to our prioritization results, approximately 48% of area converted to forests exhibited high improvements in all ecosystem services (categorized as hotspot-1, hotspot-2, and hotspot-3). The hotspots identified in this study can be used as an excellent surrogate for evaluation ecological engineering benefits and can be effectively applied in improving ecological management planning. PMID- 29600441 TI - Efficacy and Safety of the Newer Multiple Sclerosis Drugs Approved Since 2010. AB - Multiple sclerosis treatment faces tremendous changes as a result of the approval of new medications. The new medications have differing safety considerations and risks after long-term treatment, which are important for treating physicians to optimize and individualize multiple sclerosis care. Since the approval of the first multiple sclerosis capsule, fingolimod, the armamentarium of multiple sclerosis therapy has grown with the orally available medications dimethyl fumarate and teriflunomide. Fingolimod is mainly associated with cardiac side effects, dimethyl fumarate with bowel symptoms. Several reports about progressive multifocal leukoencephalopathy as a result of dimethyl fumarate or fingolimod therapy raised the awareness of fatal opportunistic infections. Alemtuzumab, a CD52-depleting antibody, is highly effective in reducing relapses but leads to secondary immunity with mainly thyroid disorders in about 30% of patients. Development of secondary B-cell-mediated disease might also be a risk of this antibody. The follow-up drug of the B-cell-depleting antibody rituximab, ocrelizumab, is mainly associated with infusion-related reactions; long-term data are scarce. The medication daclizumab high yield process, acting via the activation of CD56bright natural killer cells, can induce the elevation of liver function enzymes, but also fulminant liver failure has been reported. Therefore, daclizumab has been retracted from the market. Long-term data on the purine nucleoside cladribine in MS therapy, recently authorized in the European Union, have been acquired during the long-term follow-up of the cladribine studies. The small molecule laquinimod is currently under development. We review data of clinical trials and their extensions regarding long-term efficacy and side effects, which might be associated with long-term treatment. PMID- 29600442 TI - Spectrally decomposed dark-to-light transitions in Synechocystis sp. PCC 6803. AB - Photosynthetic activity and respiration share the thylakoid membrane in cyanobacteria. We present a series of spectrally resolved fluorescence experiments where whole cells of the cyanobacterium Synechocystis sp. PCC 6803 and mutants thereof underwent a dark-to-light transition after different dark adaptation (DA) periods. Two mutants were used: (i) a PSI-lacking mutant (DeltaPSI) and (ii) M55, a mutant without NAD(P)H dehydrogenase type-1 (NDH-1). For comparison, measurements of the wild-type were also carried out. We recorded spectrally resolved fluorescence traces over several minutes with 100 ms time resolution. The excitation light was at 590 nm so as to specifically excite the phycobilisomes. In DeltaPSI, DA time has no influence, and in dichlorophenyl dimethylurea (DCMU)-treated samples we identify three main fluorescent components: PB-PSII complexes with closed (saturated) RCs, a quenched or open PB PSII complex, and a PB-PSII 'not fully closed.' For the PSI-containing organisms without DCMU, we conclude that mainly three species contribute to the signal: a PB-PSII-PSI megacomplex with closed PSII RCs and (i) slow PB -> PSI energy transfer, or (ii) fast PB -> PSI energy transfer and (iii) complexes with open (photochemically quenched) PSII RCs. Furthermore, their time profiles reveal an adaptive response that we identify as a state transition. Our results suggest that deceleration of the PB -> PSI energy transfer rate is the molecular mechanism underlying a state 2 to state 1 transition. PMID- 29600443 TI - Immuno-receptors: from recognition to signaling and function. AB - The vertebrate adaptive immune response is initiated by specific recognition of antigens. This is carried out by molecules, soluble or cell surface receptors that are members of the Multichain Immune Recognition Receptors (MIRR) group of proteins. The soluble arm of the response is based on antibodies. Kinetic analysis of antibody-antigenic epitope interactions pioneered insights into the complexity underlying the capacity of relatively limited repertoires of antibodies to recognize an essentially unlimited range of epitopes by employing conformational diversity of a given single sequence. The arm responsible for recognition of cellular targets involves a considerably more elaborate process, predominantly of antigen-derived peptides presented bound to molecules encoded by the major histocompatibility complex (MHC). This remarkable cellular recognition process performed by T-cell receptors requires earlier steps of peptide presentation and involves interactions of the receptor sites with the array of its MHC-peptide composite ligand. In both cases, antigen recognition needs to be followed by its coupling, by biochemical cascades, to different specific responses, namely activation of effector functions. The parameters required for coupling to functional responses are still a focus of intense research. In solution, antigen-antibody aggregation is one established activation process. Those required for coupling antigen recognition to cell activation, whether by Fc receptor bound antibodies or by the B-cell antigen receptor, are also still subject to active research efforts. Though activation by immune-receptors requires antigen recognition, considerable differences could exist among the requirements set by distinct cell types. Moreover, antigen binding requiring intercellular interactions introduces additional complexity.

AB - Nitric oxide (NO) is involved many physiological plant processes, including germination, growth and development of roots, flower setting and development, senescence, and fruit ripening. In the latter physiological process, NO has been reported to play an opposite role to ethylene. Thus, treatment of fruits with NO may lead to delay ripening independently of whether they are climacteric or nonclimacteric. In many cases different methods have been reported to apply NO to plant systems involving sodium nitroprusside, NONOates, DETANO, or GSNO to investigate physiological and molecular consequences. In this chapter a method to treat plant materials with NO is provided using bell pepper fruits as a model. This method is cheap, free of side effects, and easy to apply since it only requires common chemicals and tools available in any biology laboratory. PMID- 29600444 TI - Serum YKL-40 as a biomarker for liver fibrosis in chronic hepatitis B patients with normal and mildly elevated ALT. AB - PURPOSE: YKL-40 is a chitinase-like protein expressed in multiple tissues including liver and is reported as a fibrosis marker. This study aimed to determine whether YKL-40 could serve as a diagnostic marker for the assessment of liver fibrosis in chronic hepatitis B patients with normal and mildly elevated ALT. METHODS: Six hundred and eighty-five patients with chronic hepatitis B infection were enrolled in this study from October 2013 to March 2016. All patients underwent liver biopsy and then staged based on Ishak histological system. Serum YKL-40 levels were measured by Human Magnetic Luminex Assays. RESULTS: Among chronic hepatitis B patients with normal and mildly elevated ALT, almost more than 30% of patients have significant liver fibrosis. Serum YKL-40 levels increased significantly in parallel with the progression of fibrosis in patients with ALT less than two times the upper limit of normal range (P < 0.0001). Multivariate analysis revealed that serum YKL-40, hyaluronic acid, PLT, and AST were independently associated with significant fibrosis. We established a novel YKL-40-based fibrosis model for patients with ALT less than two times the upper limit of normal range (ULN). YKL-40 model was superior to APRI, FIB-4, Forns' index, and Hui model for diagnosis of significant fibrosis in patients with ALT < 2ULN, with AUROCs of 0.786 [95% confidence interval (CI) 0.726-0.846] in the training group, 0.831 (95%CI 0.752-0.910) in the validation group and 0.801 (95%CI 0.753-0.849) in the entire cohort. CONCLUSION: Serum YKL-40 is a feasible biomarker of liver fibrosis in chronic hepatitis B patients. YKL-40 model was superior to APRI, FIB-4, Forns' index and Hui model for diagnosis of significant fibrosis in patients with normal and mildly elevated ALT. PMID- 29600447 TI - Measurements of Intra-oocyte Nitric Oxide Concentration Using Nitric Oxide Selective Electrode. AB - Precise information about the intracell nitric oxide (NO) concentration [NO] of a single cell are necessary in designing accurate experiments to further knowledge and develop treatment plans in certain disorders. The direct quantitative measurement of [NO] in situ in an intact cellular complex should be useful in tracking real-time and rapid changes at nanomolar levels. In this work, we describe the direct, real-time, and quantitative intracellular [NO] measurement utilizing an L-shaped amperometric integrated NO-selective electrode. This method not only provides an elegant and convenient approach to real-time the measurement of NO in physiological environments but also mimics the loss of NO caused by rapid NO diffusion combined with its reactivity in the biological milieu. PMID- 29600445 TI - Tumor lysate-based vaccines: on the road to immunotherapy for gallbladder cancer. AB - Immunotherapy based on checkpoint blockers has proven survival benefits in patients with melanoma and other malignancies. Nevertheless, a significant proportion of treated patients remains refractory, suggesting that in combination with active immunizations, such as cancer vaccines, they could be helpful to improve response rates. During the last decade, we have used dendritic cell (DC) based vaccines where DCs loaded with an allogeneic heat-conditioned melanoma cell lysate were tested in a series of clinical trials. In these studies, 60% of stage IV melanoma DC-treated patients showed immunological responses correlating with improved survival. Further studies showed that an essential part of the clinical efficacy was associated with the use of conditioned lysates. Gallbladder cancer (GBC) is a high-incidence malignancy in South America. Here, we evaluated the feasibility of producing effective DCs using heat-conditioned cell lysates derived from gallbladder cancer cell lines (GBCCL). By characterizing nine different GBCCLs and several fresh tumor tissues, we found that they expressed some tumor-associated antigens such as CEA, MUC-1, CA19-9, Erb2, Survivin, and several carcinoembryonic antigens. Moreover, heat-shock treatment of GBCCLs induced calreticulin translocation and release of HMGB1 and ATP, both known to act as danger signals. Monocytes stimulated with combinations of conditioned lysates exhibited a potent increase of DC-maturation markers. Furthermore, conditioned lysate-matured DCs were capable of strongly inducing CD4+ and CD8+ T cell activation, in both allogeneic and autologous cell co-cultures. Finally, in vitro stimulated CD8+ T cells recognize HLA-matched GBCCLs. In summary, GBC cell lysate-loaded DCs may be considered for future immunotherapy approaches. PMID- 29600448 TI - Real-Time Imaging of Nitric Oxide Signals in Individual Cells Using geNOps. AB - Nitric oxide (NO*) is a versatile signaling molecule which regulates fundamental cellular processes in all domains of life. However, due to the radical nature of NO* it has a very short half-life that makes it challenging to trace its formation, diffusion, and degradation on the level of individual cells. Very recently, we expanded the family of genetically encoded sensors by introducing a novel class of single fluorescent protein-based NO* probes-the geNOps. Once expressed in cells of interest, geNOps selectively respond to NO* by fluorescence quench, which enables real-time monitoring of cellular NO* signals. Here, we describe detailed methods suitable for imaging of NO* signals in mammalian cells. This novel approach may facilitate a broad range of studies to (re)investigate the complex NO* biochemistry in living cells. PMID- 29600449 TI - Detection of Nitric Oxide by Membrane Inlet Mass Spectrometry. AB - Membrane inlet mass spectrometry (MIMS) is a reproducible and reliable method for the measurement of nitric oxide in aqueous solution with a lower limit of detection of 10 nM and a linear response to 50 MUM. MIMS utilizes a semipermeable membrane to partition analytes based on physicochemical properties from the bulk sample into the mass spectrometer. Silastic tubing allows the introduction of small gaseous molecules including nitric oxide (NO) into the high vacuum of a mass spectrometer. We describe the measurement of NO generated chemically from nitrite and MAHMA NONOate as well as enzymatically by nitric oxide synthase (NOS). PMID- 29600450 TI - Quantum Cascade Lasers-Based Detection of Nitric Oxide. AB - Despite the established importance of nitric oxide (NO) in many physiological and molecular processes in plants, most methods for quantifying NO are open to criticism This reflects the differing methods either lacking specificity or sensitivity, or even from an undue dependence of results on experimental conditions (i.e., chemical concentrations, pH, etc.). In this chapter we describe a protocol to measure gaseous NO produced by a biological sample using quantum cascade laser (QCL)-based spectroscopy. This technique is based on absorption of the laser light by the NO molecules which have been passed from a biological sample into an optical s cell that is equipped with two mirrors placed at both ends. This design greatly increases the interaction path length with the NO molecules due to multiple reflections of the light coupled inside the cell. Thus, the method is able to provide online, in planta measurements of the dynamics of NO production, being highly selective and sensitive (down to ppbv levels;1 ppbv = part per billion by volume mixing ratio = 1:10-9). PMID- 29600451 TI - Detection of Nitric Oxide via Electronic Paramagnetic Resonance in Mollusks. AB - Electronic paramagnetic resonance (EPR) is an appropriate tool to identify free radicals formed in tissues under normal as well as stressful conditions. Since nitric oxide (NO) as a free radical has paramagnetic properties it can be detected by EPR. The use of spin traps highly improves the sensitivity allowing NO identification, detection and quantification at room temperature in vitro and in vivo conditions. NO production in animals is almost exclusively associated to an enzyme family known as Nitric Oxide Synthases (NOSs). The digestive glands of mollusks are a major target for oxidative disruption related to environmental stress. A simple EPR-methodology to asses both, the presence of NO and its rate of generation in tissues from different mollusk species, is reported here. PMID- 29600452 TI - Identification of S-Nitrosylated and Reversibly Oxidized Proteins by Fluorescence Switch and Complementary Techniques. AB - S-nitrosylation and other reversible oxidative posttranslational modifications of proteins are part of the nonclassical mechanisms of nitric oxide signaling. The biotin switch technique for specifically labeling S-nitrosylated proteins opened the way to proteomic identification of these modifications. Since then, several variations and adaptations of the original method have been applied.We describe here the protocols of several techniques that can be used for the proteomic identification of these modifications, as well as for the detailed characterization of the modification of individual proteins. The fluorescence switch technique allows the proteomic identification of S-nitrosylated proteins based on their fluorescent labeling coupled to electrophoretic separation, as well as the comparison of the overall modification in different samples. The redox fluorescence switch is an adaptation to detect all the proteins reversibly oxidized in cysteine residues. We also describe the protocols of complementary techniques that allow comparing the extent of modification of individual proteins in several conditions by biotin switch, and the identification of modified residues by differential labeling adapted for mass spectrometry identification. PMID- 29600453 TI - A Proteomics Workflow for Dual Labeling Biotin Switch Assay to Detect and Quantify Protein S-Nitroylation. AB - S-nitrosylation (or S-nitrosation, SNO) is an oxidative posttranslational modification to the thiol group of a cysteine amino acid residue. There are several methods to detect SNO modifications, mostly based on the classic biotin switch assay, where the labile SNO sites are replaced with a stable biotin moiety to facilitate enrichment of the modified proteins. As the technique has evolved, new and more advanced thiol-reactive reagents have been introduced in the protocol to improve the identification of modified peptides or to quantify the level of modification at individual cysteine residues. However, the growing diversity of thiol-reactive affinity tags has not produced a consistent set of protein modifications, suggesting incomplete coverage using a single tag. Here, we present a parallel dual labeling strategy followed by an optimized proteomics workflow, which maximizes the overall detection of SNO by reducing the labeling bias derived from the use of a single tag-capture approach. PMID- 29600454 TI - Surface Plasmon Resonance Spectroscopy for Detection of S-Nitrosylated Proteins. AB - Protein S-nitrosylation, the NO-dependent regulatory mechanism, is a posttranslational modification of reactive cysteine thiols to form S nitrosothiols. The biotin-switch technique (BST) has become a mainstay method for detection of S-nitrosylated proteins in biological samples. On the basis of BST, we describe a surface plasmon resonance (SPR) spectroscopy method for detecting S nitrosylated proteins. This method can be applied for the indirect determination of S-nitrosylated proteins in biological samples. PMID- 29600455 TI - Measurement of S -Nitrosoglutathione in Plasma by Liquid Chromatography-Tandem Mass Spectrometry. AB - This chapter describes an ultraperformance liquid chromatographic-tandem mass spectrometric (UPLC-MS/MS) method for the quantitative determination of S nitrosoglutathione (GSNO) in human plasma. S-[15N]Nitrosoglutathione (GS15NO) serves as the internal standard. The protocol involves inactivation of plasma gamma-glutamyltransferase activity by serine-borate, stabilization of GSNO with EDTA, and avoidance of S-transnitrosylation reactions by blocking SH groups with N-ethylmaleimidide (NEM). Fresh blood is treated with NEM/serine-borate/EDTA, plasma is spiked with GS15NO (50 nM), ultrafiltered (cutoff 10 kDa) and 10-MUL aliquots of ultrafiltrate are analyzed by UPLC-MS/MS in the positive electrospray ionization (ESI+) mode. LC is performed on a Nucleoshell column using isocratic (0.5 mL/min) elution with acetonitrile-20 mM ammonium formate (70:30, v/v), pH 7. Quantification is performed by selected-reaction monitoring the mass transition m/z 337 ([M+H]+) -> m/z 307 ([M+H-14NO]+?) for GSNO and m/z 338 ([M+H]+) -> m/z 307 ([M+H-15NO]+?) for GS15NO. Matrix effects are outweighed by the internal standard GS15NO. The lower limit of quantitation (LOQ) is 2.8 nM. PMID- 29600456 TI - Analysis of Recombinant Protein S-Nitrosylation Using the Biotin-Switch Technique. AB - Nitric oxide is regarded as a key signaling messenger in several organisms. Its physiological relevance is partly due to its capacity to induce posttranslational modifications of proteins through its direct or indirect reaction with specific amino acid residues. Among them, S-nitrosylation has been shown to be involved in a broad range of cellular signaling pathways both in animals and plants. The identification of S-nitrosylated proteins has been made possible by the development of the Biotin-Switch Technique (BST) in the early 2000s. Here, we describe the BST protocol we routinely use to check in vitro S-nitrosylation of recombinant proteins induced by NO donors. PMID- 29600457 TI - Direct Measurement of S-Nitrosothiols with an Orbitrap Fusion Mass Spectrometer: S-Nitrosoglutathione Reductase as a Model Protein. AB - Recent studies suggest cysteine S-nitrosation of S-nitrosoglutathione reductase (GSNOR) could regulate protein redox homeostasis. "Switch" assays enable discovery of putatively S-nitrosated proteins. However, with few exceptions, researchers have not examined the kinetics and biophysical consequences of S nitrosation. Methods to quantify protein S-nitrosothiol (SNO) abundance and formation kinetics would bridge this mechanistic gap and allow interpretation of the consequences of specific modifications, as well as facilitate development of specific S-nitrosation inhibitors. Here, we describe a rapid assay to estimate protein SNO abundance with intact protein electrospray ionization mass spectrometry. Originally designed using recombinant GSNOR, these methods are applicable to any purified protein to test for or further study nitrosatable cysteines. PMID- 29600458 TI - Identification of Tyrosine and Nitrotyrosine with a Mixed-Mode Solid-Phase Extraction Cleanup Followed by Liquid Chromatography-Electrospray Time-of-Flight Mass Spectrometry in Plants. AB - In higher plants, there is a growing interest in the study of protein tyrosine nitration (NO2Tyr) as well as the identification of in vivo nitrated proteins. Different methods have been developed for identifying nitrotyrosine in biological samples. However, these analyses are difficult because tyrosine nitration is a very low-abundance posttranslational protein modification (PTM) and the lack of efficient enrichment methods for detection. The identification and quantification of NO2Tyr in proteins has represented a challenge for researchers.In this chapter a new method for determining NO2Tyr and tyrosine (Tyr) in Arabidopsis thaliana cell-suspension culture extracts is proposed. The quantification was performed using a simple, sensitive, and specific sample preparation assay based on mixed mode solid-phase extraction (SPE) which was developed for the quantification of trace NO2Tyr in Arabidopsis extracts by liquid chromatography-electrospray time of-flight mass spectrometry (LC-TOFMS). PMID- 29600459 TI - Electrophoretic Detection and Confocal Microscopic Imaging of Tyrosine Nitrated Proteins in Plant Tissue. AB - Tyrosine nitrated proteins can be detected in plant cells electrophoretically and their distribution can be monitored by confocal laser scanning microscopy (CLSM) imaging. One-dimensional polyacrylamide gel electrophoresis (1D PAGE) followed by Western blotting using polyclonal antibody against 3-nitrotyrosine residues enables detection of tyrosine nitrated proteins in plant cells. Here we describe detection of tyrosine nitrated proteins in the homogenates derived from sunflower (Helianthus annuus L.) seedling cotyledons. Total soluble proteins obtained from tissue homogenates are resolved using vertical gel electrophoresis followed by their electrophoretic transfer on to a microporous membrane support for immunodetection. Spatial distribution of tyrosine nitrated proteins can be visualized using an antibody against 3-nitrotyrosine residues. Immunofluorescent localization is performed by cutting 7 MUm thick wax sections of tissue followed by incubation in primary anti-nitrotyrosine antibody (dilution 1:200) and secondary Cy-3 labeled anti-rabbit IgG antibody (dilution 1:1500). Confocal laser scanning microscopy analysis is undertaken using argon lasers (ex: 530-550 nm and em: 570 nm) at pinhole 1. Modulation in the abundance and spatial localization of tyrosine nitrated proteins in plant tissues can be monitored using these techniques. PMID- 29600460 TI - Identification of NO-Sensitive Cysteine Residues Using Cysteine Mutants of Recombinant Proteins. AB - Nitric oxide (NO) is a free radical gas regulating a wide range of biological processes in plants. Proteins are the main reaction target of NO inside the cells. The relevance of S-nitrosation as one of the NO-mediated protein posttranslational modifications has been studied in detail. S-nitrosylation causes alterations of the activity/function, sub-cellular localization or interaction partners of proteins. Up to present, a large number of S-nitrosation candidates have been detected in plants. Recombinant proteins are widely used to show or confirm the protein posttranslational modifications. Here, using recombinant proteins subjected to biotin switch assay, the S-nitrosation of some nuclear candidates of Arabidopsis is verified. Proteins usually contain several cysteine residues which each might involve in structure of protein active sites. So, an important question is: which cysteine residue is the target of S nitrosation and does it belong to an active site? Here, using the approach of substitution of cysteines by serines on recombinant proteins, the NO-sensitive cysteine residue of an Arabidopsis nuclear protein is identified. The next step could be to investigate the effect of S-nitrosation on protein activity/function and further to test the role of target cysteines and S-nitrosation of them in protein activity/function. PMID- 29600461 TI - Detection of S-Nitrosated Nuclear Proteins in Pathogen-Treated Arabidopsis Cell Cultures Using Biotin Switch Technique. AB - Nitric oxide (NO) is an important signaling molecule involved in various plant physiological processes. The main effect of NO arises from its reaction with proteins. S-Nitrosation is the most studied NO-mediated protein posttranslational modification in plants. Via S-nitrosation, NO derivatives react with thiol groups (SHs) of protein cysteine residues and produce nitrosothiol groups (SNOs). From the time of discovering the biological function of NO in plants, an interesting case of study has been the detection of the endogenous S-nitrosated proteins in different plants, tissues, organelles, and various conditions. Maps of S nitrosated proteins provide hints for deeper studies on the function of this modification in specific proteins, biochemical pathways, and physiological processes. Many functions of NO have been found to be related to plant defense; on the other hand the involvement of nuclear proteins in regulation of plant defense reactions is well studied. Here, an approach is described in which the Arabidopsis cell cultures first are treated with P. syringae, afterward their bioactive nuclear proteins are extracted, then the nuclear proteins are subjected to biotin switch assay in which S-nitrosated proteins are specifically converted to S-biotinylated proteins. The biotin switch technique (BST) which was introduced by Jaffrey et al. (Nat Cell Biol 3:193-197, 2001) solves the instability issue of SNOs. Additionally, it provides detection and purification of biotinylated proteins by anti-biotin antibody and affinity chromatography, respectively. PMID- 29600462 TI - Nitric Oxide Analyzer Quantification of Plant S-Nitrosothiols. AB - Nitric oxide (NO) is a small diatomic molecule that regulates multiple physiological processes in animals, plants, and microorganisms. In animals, it is involved in vasodilation and neurotransmission and is present in exhaled breath. In plants, it regulates both plant immune function and numerous developmental programs. The high reactivity and short half-life of NO and cross-reactivity of its various derivatives make its quantification difficult. Different methods based on calorimetric, fluorometric, and chemiluminescent detection of NO and its derivatives are available, but all of them have significant limitations. Here we describe a method for the chemiluminescence-based quantification of NO using ozone-chemiluminescence technology in plants. This approach provides a sensitive, robust, and flexible approach for determining the levels of NO and its signaling products, protein S-nitrosothiols. PMID- 29600463 TI - Nitro-Fatty Acid Detection in Plants by High-Pressure Liquid Chromatography Coupled to Triple Quadrupole Mass Spectrometry. AB - In the last few years, the role of nitric oxide (NO) and NO-related molecules has attracted attention in the field of plant systems. In this sense, the ability of NO to mediate several posttranslational modifications (NO-PTM) in different biomolecules, such as protein tyrosine nitration or S-nitrosylation, has shown the involvement of these reactive nitrogen species in a wide range of functions in plant physiology such as the antioxidant response or the involvement in processes such as germination, growth, development, or senescence. However, growing interest has focused on the interaction of these NO-derived molecules with unsaturated fatty acids, yielding nitro-fatty acids (NO2-FAs). It has recently been shown that these molecules are involved in key signaling pathways in animal systems through the implementation of antioxidant and anti-inflammatory responses. Nevertheless, this interaction has been poorly studied in plant systems. Very recently, the endogenous presence of NO2-FAs in the model plant Arabidopsis thaliana has been demonstrated as well as the significant involvement of nitro-linolenic acid (NO2-Ln) in the defence response against several abiotic and oxidative stress conditions. In this respect, the detection of NO2-FAs in plant systems can be a useful tool to determine the importance of these molecules in the regulation of different biochemical pathways. Using high-pressure liquid chromatography coupled to triple quadrupole mass spectrometry (LC-MS/MS), the methods described in this chapter enable the determination of the NO2-FA content in a pM range as well as the characterization of these nitrated derivatives of unsaturated fatty acids in plant tissues.

AB - S-nitrosylation is an essential and reversible posttranslational modification of proteins involved in numerous biological processes. The experimental determination of S-nitrosylation sites is laborious and time-consuming. Therefore, the use of computational prediction tools of this modification represents a convenient first approach to generate useful information for subsequent experimental verification. Here we describe an in silico analysis pipeline to integrate the use of several bionformatic tools while dealing with big query protein sets. PMID- 29600465 TI - Biotin Switch Processing and Mass Spectrometry Analysis of S-Nitrosated Thioredoxin and Its Transnitrosation Targets. AB - S-Nitrosation is a key posttranslational modification in regulating proteins in both normal physiology and diverse human diseases. To identify novel therapies for human diseases linked to oxidative and nitrosative stress, understanding how cells control S-nitrosation specificity could be critical. Among the enzymes known to control S-nitrosation of proteins, thioredoxin 1 (Trx1), a conserved disulfide reductase, transnitrosates and denitrosates distinct sets of target proteins. To recognize the function of Trx1 in both normal and dysfunctional cells, S-nitrosation targets of Trx1 in different cells need to be identified. However, S-nitrosation is usually too labile to be detected directly by mass spectrometry (MS). Here we present two optimized MS techniques to identify S nitrosated Trx1 and its transnitrosation targets, using both direct and indirect MS methods. PMID- 29600466 TI - Immunodetection of S-Nitrosoglutathione Reductase Protein in Plant Samples. AB - S-nitrosation, the attachment of a nitroso group to cysteine thiols, has been recognized as an important posttranslational modification of proteins by nitric oxide and related reactive nitrogen species. Mechanisms and significance of S nitrosation in the regulation of the structure and activity of proteins have been extensively studied in animal and plant systems. In plants, protein S-nitrosation is involved in signaling pathways of plant hormones and regulators during plant growth and development and in responses to abiotic and biotic stress stimuli. S nitrosoglutathione reductase (GSNOR) has been identified as a key enzyme controlling the intracellular level of S-nitrosothiols. GSNOR irreversibly degrades S-nitrosoglutathione (GSNO), the major low molecular weight S nitrosothiol involved in the formation of protein S-nitrosothiols through transnitrosylation. GSNOR level and activity in plant cells are modulated during plant development and in response to external stimuli such as pathogen infection. In this chapter, we give a detailed description of the immunochemical detection of the GSNOR protein in plant samples. PMID- 29600467 TI - Thioredoxin-Dependent Decomposition of Protein S-Nitrosothiols. AB - The addition of nitric oxide to cysteine moieties of proteins results in the formation of S-nitrosothiols (SNO) that have emerged as important posttranslational signaling cues in a wide variety of eukaryotic processes. While formation of protein-SNO is largely nonenzymatic, the conserved family of Thioredoxin (TRX) enzymes are capable of selectively reducing protein-SNO. Consequently, TRX enzymes are thought to provide reversibility and specificity to protein-SNO signaling networks. Here, we describe an in vitro methodology based on enzymatic oxidoreductase and biotin-switch techniques, allowing for the detection of protein-SNO targets of TRX enzymes. We show that this methodology identifies both global and specific protein-SNO targets of TRX in plant cell extracts. PMID- 29600468 TI - Multivariate analysis for source identification of pollution in sediment of Linggi River, Malaysia. AB - Rapid socioeconomic development in the Linggi River Basin has contributed to the significant increase of pollution discharge into the Linggi River and its adjacent coastal areas. The toxic element contents and distributions in the sediment samples collected along the Linggi River were determined using neutron activation analysis (NAA) and inductively coupled plasma-mass spectrometry (ICP MS) techniques. The measured mean concentration of As, Cd, Pb, Sb, U, Th and Zn is relatively higher compared to the continental crust value of the respective element. Most of the elements (As, Cr, Fe, Pb, Sb and Zn) exceeded the freshwater sediment quality guideline-threshold effect concentration (FSQG-TEC) value. Downstream stations of the Linggi River showed that As concentrations in sediment exceeded the freshwater sediment quality guideline-probable effect concentration (FSQG-PEC) value. This indicates that the concentration of As will give an adverse effect to the growth of sediment-dwelling organisms. Generally, the Linggi River sediment can be categorised as unpolluted to strongly polluted and unpolluted to strongly to extremely polluted. The correlation matrix of metal metal relationship, principle component analysis (PCA) and cluster analysis (CA) indicates that the pollution sources of Cu, Ni, Zn, Cd and Pb in sediments of the Linggi River originated from the industry of electronics and electroplating. Elements of As, Cr, Sb and Fe mainly originated from motor-vehicle workshops and metal work, whilst U and Th originated from natural processes such as terrestrial runoff and land erosion.

PMID- 29600470 TI - Photokinetic Drug Delivery: Near infrared (NIR) Induced Permeation Enhancement of Bevacizumab, Ranibizumab and Aflibercept through Human Sclera. AB - PURPOSE: Permeation studies, with near infrared (NIR) light and anti-aggregation antibody formulation, were used to investigate the in vitro permeation of bevacizumab, ranibizumab and aflibercept through human sclera. METHODS: A vertical, spherical Franz cell diffusion apparatus was used for this scleral tissue permeation model. A photokinetic ocular drug delivery (PODD) testing device accommodated the placement of NIR LEDs above the donor chambers. An adjustable LED driver/square wave generator provided electrical energy with a variable pulse rate and pulse width modulation (duty cycle). RESULTS: Exposure to non-thermal NIR light had no effect on mAbs with regard to monomer concentration or antibody binding potential, as determined by SE-HPLC and ELISA. The optimal LED wavelength was found to be 950 nm. Duty cycle power of 5% vs 20% showed no difference in permeation. When compared to controls, the combination of non aggregating antibody formulation and NIR illumination provided an average transscleral drug flux enhancement factor of 3X. CONCLUSION: Narrow wavelength incoherent (non-laser) light from an NIR LED source is not harmful to mAbs and can be used to enhance drug permeation through scleral tissue. The topical formulation, combined with pulsed NIR light irradiation, significantly improved scleral permeation of three anti-VEGF antibody drugs. PMID- 29600471 TI - Migration Background Influences Consumption Patterns Based on Dietary Recommendations of Food Bank Users in Germany. AB - People with low income tend to eat less balanced than people with higher income. This seems to be particularly the case for people with migration background. This cross-sectional study examined the relation of consumption patterns of 597 food bank users with different migration background in Germany. Questionnaires were distributed assessing sociodemographic information and consumption patterns. Analyses were conducted using binary logistic regressions. Models were controlled for age, gender, type of household and education. The group of German food bank users consumed fewer fruits and vegetables and less fish compared to all other groups with migration background (former USSR, Balkan region, Middle East). A significant predictor for fruit and vegetable consumption was migration status. Participants from the former USSR consumed less often SSBs compared to the other groups. Dietary recommendations for low income populations should take into consideration other aspects besides income such as migration status. PMID- 29600472 TI - Maternal consumption of coffee and tea during pregnancy and risk of childhood ALL: a pooled analysis from the childhood Leukemia International Consortium. AB - PURPOSE: The early onset of childhood acute lymphoblastic leukemia (ALL) suggests that critical exposures occurring during pregnancy may increase risk. We investigated the effects of maternal coffee and tea consumption during pregnancy on ALL risk by pooling data from eight case-control studies participating in the Childhood Leukemia International Consortium. METHOD: Data on maternal coffee intake were available for 2,552 cases and 4,876 controls, and data on tea intake were available for 2,982 cases and 5,367 controls. Coffee and tea intake was categorized into 0, > 0-1, > 1-2, and > 2 cups/day, and covariates were combined and harmonized. Data on genetic variants in NAT2, CYP1A1, and NQO1 were also available in a subset. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression, and linear trends across categories were assessed. RESULTS: No association was seen with 'any' maternal coffee consumption during pregnancy, but there was evidence of a positive exposure-response; the pooled OR for > 2 cups/day versus none was 1.27 (95% CI 1.09-1.43), p trend = 0.005. No associations were observed with tea consumption. No interactions were seen between coffee or tea intake and age, maternal smoking or genotype, and there was little or no evidence that associations with coffee or tea differed among cases with and without chromosomal translocations. CONCLUSIONS: Despite some limitations, our findings suggest that high coffee intake during pregnancy may increase risk of childhood ALL. Thus, current advice to limit caffeine intake during pregnancy to reduce risk of preterm birth may have additional benefits. PMID- 29600473 TI - Psychosocial Stress and Preterm Birth: The Impact of Parity and Race. AB - Objectives Studies examining risk factors for preterm birth (PTB) such as psychosocial stress are often focused on women with a history of PTB; however, most preterm babies are born to women with no history of preterm birth. Our objective was to determine if the relationship between psychosocial stress and PTB is altered by parity. Non-Hispanic black (NHB) women have increased psychosocial stress and PTB; therefore, we further aimed to determine if race alters the relationship between psychosocial stress, parity, and PTB. Methods We performed a secondary analysis of the Healthy Pregnancy, Healthy Baby Study comparing pregnant women who were primiparous (first pregnancy), multiparous with history of preterm birth, or multiparous with history of term birth. Perceived stress, perceived racism, interpersonal support, John Henryism and self-efficacy were measured using validated instruments. Logistic regression was used to model the effect of psychosocial stress on PTB stratified by parity and race. Results The analysis entire cohort included 1606 subjects, 426 were primiparous, 268 had a history of presterm birth, and 912 had a history of term birth. In women with a history of term birth, higher self-efficacy was associated with lower odds of spontaneous PTB, and this association was amplified in NHB women. In women with a history of spontaneous PTB, John Henryism Active Coping was associated with lower odds of spontaneous PTB in the index pregnancy. Conclusions for Practice The relationship between psychosocial stress and PTB may be mediated by parity and race. PMID- 29600474 TI - Combined percutaneous radiofrequency ablation and ethanol injection versus hepatic resection for 2.1-5.0 cm solitary hepatocellular carcinoma: a retrospective comparative multicentre study. AB - OBJECTIVES: To compare combined percutaneous radiofrequency ablation and ethanol injection (RFA-PEI) with hepatic resection (HR) in the treatment of resectable solitary hepatocellular carcinoma (HCC) with 2.1-5.0 cm diameter. METHODS: From June 2009 to December 2015, 271 patients whom underwent RFA-PEI (n = 141) or HR (n = 130) in three centres were enrolled. The overall survival (OS) and recurrence-free survival (RFS) between groups were compared with Kaplan-Meier method and log-rank tests. Complications, hospital stay and cost were assessed. RESULTS: The OS rates at 1, 3 and 5 years were 93.5%, 72.7%, 58.6% in RFA-PEI group and 82.3%, 57.5%, 51.8% in HR group (p = 0.021). The corresponding 1-, 3- and 5-year RFS rates were 65.8%, 41.3%, 34.3% in RFA-PEI group and 50.5%, 33.8%, 28.4% in HR group (p = 0.038). For patients with 2.1-3.0 cm tumours, the 1-, 3- and 5-year OS after RFA-PEI and HR were 98.0%, 82.3%, 74.2% and 89.4%, 65.1%, 61.9%, respectively (p = 0.024). The corresponding RFS were 79.6%, 54.7%, 45.1% in RFA-PEI group, and 57.6%, 43.9%, 31.7% in HR group, respectively (p = 0.020). RFA-PEI was superior to HR in major complication rates, length of hospital stay and cost (all p < 0.001). CONCLUSION: RFA-PEI had a survival benefit over HR in the treatment of solitary HCCs, especially for those with 2.1-3.0 cm in diameter. KEY POINTS: * RFA-PEI provided superior survival to HR in solitary HCC with 2.1 5.0 cm in diameter. * RFA-PEI is superior to HR in complications, length of hospital stay and cost. * RFA-PEI might be an alternative treatment for solitary HCC within 5.0 cm in diameter. PMID- 29600475 TI - Structured reporting adds clinical value in primary CT staging of diffuse large B cell lymphoma. AB - OBJECTIVES: To evaluate whether template-based structured reports (SRs) add clinical value to primary CT staging in patients with diffuse large B-cell lymphoma (DLBCL) compared to free-text reports (FTRs). METHODS: In this two centre study SRs and FTRs were acquired for 16 CT examinations. Thirty-two reports were independently scored by four haematologists using a questionnaire addressing completeness of information, structure, guidance for patient management and overall quality. The questionnaire included yes-no, 10-point Likert scale and 5-point scale questions. Altogether 128 completed questionnaires were evaluated. Non-parametric Wilcoxon signed-rank test and McNemar's test were used for statistical analysis. RESULTS: SRs contained information on affected organs more often than FTRs (95 % vs. 66 %). More SRs commented on extranodal involvement (91 % vs. 62 %). Sufficient information for Ann-Arbor classification was included in more SRs (89 % vs. 64 %). Information extraction was quicker from SRs (median rating on 10-point Likert scale=9 vs. 6; 7-10 vs. 4-8 interquartile range). SRs had better comprehensibility (9 vs. 7; 8-10 vs. 5-8). Contribution of SRs to clinical decision-making was higher (9 vs. 6; 6-10 vs. 3-8). SRs were of higher quality (p < 0.001). All haematologists preferred SRs over FTRs. CONCLUSIONS: Structured reporting of CT examinations for primary staging in patients with DLBCL adds clinical value compared to FTRs by increasing completeness of reports, facilitating information extraction and improving patient management. KEY POINTS: * Structured reporting in CT helps clinicians to assess patients with lymphoma. * This two-centre study showed that structured reporting improves information content and extraction. * Patient management may be improved by structured reporting. * Clinicians preferred structured reports over free-text reports. PMID- 29600476 TI - Percutaneous transhepatic intrahepatic portosystemic shunt for variceal bleeding with chronic portal vein occlusion after splenectomy. AB - OBJECTIVES: The purpose of this study was to introduce a modified transjugular intrahepatic portosystemic shunt (TIPS), a percutaneous transhepatic intrahepatic portosystemic shunt (PTIPS), and to evaluate its feasibility and efficacy in patients with variceal bleeding with chronic portal vein occlusion (CPVO) after splenectomy. METHODS: Twenty-four cirrhotic patients with CPVO after splenectomy who received PTIPS between 2010 and 2015 were included in this retrospective study. The indication was elective control of variceal bleeding. Success rates, effectiveness and complications were evaluated, with comparison of the pre- and post-portosystemic pressure gradient (PPG). Patients' clinical outcomes and shunt patency were followed periodically. RESULTS: PTIPS was successfully placed in 22 patients (91.7%) and failed in two. The mean PPG fell from 22.0 +/- 4.9 mmHg to 10.6 +/- 1.6 mmHg after successful PTIPS (p < 0.05). No fatal procedural complications occurred. During the median follow-up of 29 months, shunt dysfunction occurred in five cases and hepatic encephalopathy in four cases. Three patients died because of rebleeding, hepatic failure and pulmonary disease, respectively. The other patients remained asymptomatic and the shunts patent. CONCLUSIONS: We conclude that PTIPS, as a modified TIPS procedure with a high success rate, is safe and effective for variceal bleeding with CPVO after splenectomy. KEY POINTS: * Portal vein occlusion used to be contraindication to transjugular intrahepatic portosystemic shunt. * Portal vein thrombosis is common in patients with previous splenectomy. * We developed a new method, percutaneous transhepatic intrahepatic portosystemic shunt (PTIPS). * PTIPS is feasible in patients with portal vein thrombosis and splenectomy. * PTIPS is effective and safe for these kind of complicated portal hypertension. PMID- 29600477 TI - In vivo study of enhanced chemotherapy combined with ultrasound image-guided focused ultrasound (USgFUS) treatment for pancreatic cancer in a xenograft mouse model. AB - OBJECTIVES: This study was designed to investigate whether focused ultrasound (FUS) treatment with a higher mechanical index (MI) can enhance the effects of combined chemotherapy more than with a lower MI, and to evaluate the feasibility of the chemotherapy combined with FUS at a higher MI as an alternative treatment protocol. METHODS: Mice in the first study were divided into six groups: control, chemotherapy only (GEM), two groups treated with FUS only at two different MIs, and two groups treated with chemotherapy and FUS (GEM + FUS). Mice were treated with a single-session treatment; one session consisted of three weekly treatments and 1 week of follow-up monitoring. In the second study, mice were assigned to two groups (GEM, GEM + FUS) and treated with four treatment sessions. RESULTS: In the single-session treatment, tumor growth was most effectively suppressed in GEM + FUS group with a higher MI. Tumor growth rate was significantly lower in GEM + FUS group than in GEM group for multiple-session treatment. Specifically, three of ten mice in GEM + FUS group showed complete remission. CONCLUSIONS: This study demonstrated that FUS at a higher MI can enhance chemotherapy outcomes more than at a lower MI and demonstrated the potential of FUS in combination with chemotherapy as a new cancer treatment protocol. KEY POINTS: * Combined treatment of chemotherapy and focused ultrasound can effectively suppress tumor growth. * For the focused ultrasound treatment conditions used in this study, focused ultrasound with relatively higher mechanical index shows more enhanced therapeutic outcomes than with the lower mechanical index. * Combination therapy shows the possibility as a new cancer treatment protocol. PMID- 29600478 TI - Abnormal brain structure as a potential biomarker for venous erectile dysfunction: evidence from multimodal MRI and machine learning. AB - OBJECTIVES: To investigate the cerebral structural changes related to venous erectile dysfunction (VED) and the relationship of these changes to clinical symptoms and disorder duration and distinguish patients with VED from healthy controls using a machine learning classification. METHODS: 45 VED patients and 50 healthy controls were included. Voxel-based morphometry (VBM), tract-based spatial statistics (TBSS) and correlation analyses of VED patients and clinical variables were performed. The machine learning classification method was adopted to confirm its effectiveness in distinguishing VED patients from healthy controls. RESULTS: Compared to healthy control subjects, VED patients showed significantly decreased cortical volumes in the left postcentral gyrus and precentral gyrus, while only the right middle temporal gyrus showed a significant increase in cortical volume. Increased axial diffusivity (AD), radial diffusivity (RD) and mean diffusivity (MD) values were observed in widespread brain regions. Certain regions of these alterations related to VED patients showed significant correlations with clinical symptoms and disorder durations. Machine learning analyses discriminated patients from controls with overall accuracy 96.7%, sensitivity 93.3% and specificity 99.0%. CONCLUSIONS: Cortical volume and white matter (WM) microstructural changes were observed in VED patients, and showed significant correlations with clinical symptoms and dysfunction durations. Various DTI-derived indices of some brain regions could be regarded as reliable discriminating features between VED patients and healthy control subjects, as shown by machine learning analyses. KEY POINTS: * Multimodal magnetic resonance imaging helps clinicians to assess patients with VED. * VED patients show cerebral structural alterations related to their clinical symptoms. * Machine learning analyses discriminated VED patients from controls with an excellent performance. * Machine learning classification provided a preliminary demonstration of DTI's clinical use. PMID- 29600479 TI - CT analysis of the aorta in giant-cell arteritis: a case-control study. AB - OBJECTIVES: Giant cell arteritis (GCA) is a large-vessel vasculitis whose diagnosis is confirmed by temporal artery biopsy. However, involvement of large vessels, especially the aorta, can be shown by imaging, which plays an increasing role in GCA diagnosis. The threshold above which aortic wall thickening, as measured by computed tomography (CT), is considered pathological is controversial, with values ranging from 2 to 3 mm. This study assessed aortic morphology by CT scan and its diagnostic value in GCA. METHODS: Altogether, 174 patients were included (64 with GCA, 43 with polymyalgia rheumatica and 67 controls). All patients had a CT scan at diagnosis or at inclusion for controls. Aortic wall thickness, aortic diameter and scores for atheroma were measured. Assessor was blinded to each patient's group. RESULTS: Aortic diameters and atheroma scores were similar between groups. Aortic wall thickness was greater in the GCA group, even after the exclusion of GCA patients with aortic wall thickness >=3 mm. The receiver operating characteristic (ROC) curve showed that a wall thickness of 2.2 mm was the optimal threshold to diagnose GCA (sensitivity, 67%; specificity, 98%). CONCLUSIONS: Measuring aortic wall thickness by CT scan is effective to diagnose GCA. The optimal threshold to regard aortic wall thickening as pathological was >=2.2 mm. KEY POINTS: * Imaging, including CT scan, plays an increasing role in GCA diagnosis * CT measurement of aortic wall thickness is useful to diagnose GCA * A 2.2-mm threshold allows the diagnosis of thickened aortic wall in GCA. PMID- 29600481 TI - Similarities between the irrelevant sound effect and the suffix effect. AB - Although articulatory suppression abolishes the effect of irrelevant sound (ISE) on serial recall when sequences are presented visually, the effect persists with auditory presentation of list items. Two experiments were designed to test the claim that, when articulation is suppressed, the effect of irrelevant sound on the retention of auditory lists resembles a suffix effect. A suffix is a spoken word that immediately follows the final item in a list. Even though participants are told to ignore it, the suffix impairs serial recall of auditory lists. In Experiment 1, the irrelevant sound consisted of instrumental music. The music generated a significant ISE that was abolished by articulatory suppression. It therefore appears that, when articulation is suppressed, irrelevant sound must contain speech for it to have any effect on recall. This is consistent with what is known about the suffix effect. In Experiment 2, the effect of irrelevant sound under articulatory suppression was greater when the irrelevant sound was spoken by the same voice that presented the list items. This outcome is again consistent with the known characteristics of the suffix effect. It therefore appears that, when rehearsal is suppressed, irrelevant sound disrupts the acoustic-perceptual encoding of auditorily presented list items. There is no evidence that the persistence of the ISE under suppression is a result of interference to the representation of list items in a postcategorical phonological store. PMID- 29600480 TI - Fragmented particles containing octreotide acetate prepared by spray drying technique for dry powder inhalation. AB - Dry powder inhalers (DPIs) have been proposed as an alternative administration route for protein and peptide drugs. However, DPI particles are easy to aggregate due to the strong interactions between the particles, leading to poor aerosolization performance. In this study, fragmented particles containing octreotide acetate (OA) were prepared by spray drying technique for dry powder inhalation, which were expected to decrease the particle-particle interaction by reducing the contact sites. Mannitol and ammonium carbonate were used as protein stabilizer and fragment-forming agent, respectively. The obtained fragmented particles presented larger particle size, lower density, better dispersibility, and well in vitro aerodynamic behavior (emitted dose > 97%, fine particle fraction ~ 40%). The circular dichroism spectrum results indicated that OA maintained the stability throughout the spray drying process. The relative bioavailability of dry powder inhalation (DPI) compared with subcutaneous injection of commercial product was up to 88.0%, demonstrating the feasibility of DPI for OA delivery. These results confirmed that the proposed fragmented particles had great potential for pulmonary delivery of protein and peptide drugs in a painless, rapid, and convenient manner. PMID- 29600482 TI - Pectoral nerves I block is associated with a significant motor blockade with no dermatomal sensory changes: a prospective volunteer randomized-controlled double blind study. AB - PURPOSE: The pectoral nerves (PECS) I block, first described in 2011 for surgery involving the pectoralis muscle, has principally been used for breast cancer surgery. No formal evaluation of its differential motor- and sensory-blocking abilities has been reported. We hypothesize that the PECS I block will produce a motor block of the pectoralis muscles with diminished upper limb adduction strength as measured with a handheld dynamometer. METHODS: We conducted a PECS I block in a randomized placebo-controlled trial in six healthy subjects who received 0.4 mL.kg-1 of 0.9% saline (placebo) on one side and bupivacaine (0.25% with 1:400 000 epinephrine) on the other. We measured both upper limb adduction strength with a dynamometer and sensory skin levels over the thorax. RESULTS: The mean (standard deviation [SD]) adductor strength evaluated before the block was 119.4 (20.7) Newtons (N). After the PECS I block with bupivacaine, the mean (SD) strength of 54.2 (16.3) N was compared with 116.0 (30.4) N in the placebo group (difference in means 61.8 N; 95% confidence interval [CI], 27.8 to 95.8 N; P = 0.005), showing a 54.6% (95% CI, 43.6 to 65.6%) reduction in adductor strength. There was no difference in dermatomal skin sensory testing between the placebo and bupivacaine sides. CONCLUSIONS: This study shows that a PECS I block produces motor blockade as shown by reduced upper limb adductor strength without any overlying dermatomal sensory loss.

AB - PURPOSE: This continuing professional development module aims to prepare anesthesiologists for the timely recognition and management of a malignant hyperthermia (MH) reaction, which is crucial for averting its life-threatening complications and ultimately for the patient's survival. PRINCIPAL FINDINGS: Malignant hyperthermia is a genetic disorder of skeletal muscle cells affecting myoplasmic calcium homeostasis. It can present with nonspecific signs of a hypermetabolic reaction, which can be fatal if treatment, including administration of dantrolene sodium, is not implemented promptly. Rapid evaluation and rejection of alternative diagnoses can lead to a prompt diagnosis and treatment and therefore will significantly reduce the complications, including renal failure, cardiac dysfunction, disseminated intravascular coagulation, and death. After the reaction, patients should be observed for a minimum of 24 hr because of the possibility of recrudescence. As it is a genetic condition, survivors and their family members should be referred to a specialized MH centre for further testing and counselling. CONCLUSIONS: The risk of dying from MH has increased over the past few years. A knowledgeable anesthesiologist who is diligent and attentive can recognize signs of an impending MH reaction and treat promptly to avoid complications of this deadly condition. PMID- 29600484 TI - Morphometrics of the Southern Green Stink Bug [Nezara viridula (L.) (Hemiptera: Pentatomidae)] Stylet Bundle. AB - The southern green stink bug, Nezara viridula (L.) (Hemiptera: Pentatomidae), is a cosmopolitan pest of high-value cash crops, including cotton (Gossypium hirsutum L.; Malvales: Malvaceae). The pest can ingest and transmit disease causing bacterial and fungal pathogens of cotton. We hypothesized that the size of the food canal may contribute to selective transmission, as observed in previous reports. The objective of this study was to examine food canal size and other morphometric parameters of the southern green stink bug stylet bundle at two locations (labium and head) to improve our understanding of factors that may contribute to pathogen transmission. For the food canal, females possessed significantly larger canals than males, major axes were significantly longer than minor axes, and canal sizes were numerically higher at the labium compared with the head. For salivary canal, mean axes lengths were similar between sexes and the head and labium. For both food and salivary canals, axes lengths were longer and area was larger at the labium compared with the head. These findings indicate the presence of a "funnel effect" with canals becoming narrower proximally. Sex and location significantly affected the size of the intact stylet bundle. Results indicate the food canal size was not a factor affecting previously observed selective passive transmission. Major and minor axes measurements, coupled with morphological observations of canal shapes and observed "funnel effect" in the food and salivary canals, improve our understanding of the hemipteran stylet bundle and its relationship with the insect's internal morphology. PMID- 29600485 TI - Diffuse fibrosis is common in the left, but not in the right ventricle in patients with transposition of the great arteries late after atrial switch operation. AB - In adult patients with transposition of the great arteries (TGA) late after atrial switch operation (AtSO), each of the ventricles is faced with a profoundly different pressure regimen from the one they are meant to support in normal conditions. The extent of diffuse fibrosis of the right ventricle (RV) and left ventricle (LV) in these patients remains incompletely investigated. Aim of this study was to quantify the degree of fibrosis of the unloaded LV and of the overloaded RV by determining the myocardial extracellular volume (ECV) with non invasive techniques as T1 mapping. We determined ECV by cardiac magnetic resonance (CMR) in 10 patients (36.8 +/- 5.3 years old) with TGA late after AtSO, without relevant pulmonary stenosis, by acquiring T1-maps of the myocardium before and 10 min after injection of Gadolinium-based contrast agent. ECV of the inferior wall (36% (33-41%)) and of the lateral wall (37% (35-39%)) of the LV was significantly increased compared to the ECV of the RV (27% (25-29%)), in both comparisons P < 0.0001. Long-time LV unloading following atrial switch procedures leads to severe myocardial fibrosis of the subpulmonary LV. T1 mapping CMR might be useful for selection of patients with atrial switch operation, in whom reestablishment of the LV as a systemic ventricle by staged arterial switch operation is planned. However larger studies and newer higher resolution methods for T1-mapping are needed to determine the role of ECV in the decision of a surgical intervention in this kind of population. PMID- 29600488 TI - Origin and location of new Arctic islands and straits due to glacial recession. AB - A total of 34 new islands (each 0.5 km2 or above) have appeared due to recession of Arctic glaciers under climate warming since the 1960s. Analysis of maps and satellite images of the Arctic coasts has been a basic method of recognizing these islands. Their origin is the final stage of a process which began in the twentieth century. They appear only on the coasts where bedrock elevations above sea level are surrounded by depressions below this level, filled (at least from the landside) with glaciers. Their recession leads to flooding of the depressions by sea water, thus creating straits which separate the new islands from the mainland. Hence, such new islands appear only in Greenland and the European Arctic. Their ecosystems accommodate to new environmental conditions. In the near future, this process will be intensified in a situation of further warming. PMID- 29600486 TI - Influence of corticosteroid therapy on IL-18 and nitric oxide production during Behcet's disease. AB - BACKGROUND AND AIMS: Behcet's disease (BD) is a chronic multisystemic inflammatory disease with complex etiopathogenesis. Th1-proinflammatory cytokines seem to be involved in its pathogenesis. Our current study aims to evaluate interleukin-18 (IL-18) and nitric oxide (NO) involvement in the development of different clinical manifestations of BD as well as to investigate the corticosteroid therapy effect on this production in Algerian patients. METHODS: For this purpose, we evaluated in vivo and ex vivo IL-18, interferon-gamma (IFN gamma) levels using ELISA and NO production by the Griess' method in naive-active and corticosteroid-treated BD patients with different clinical manifestations. Additionally, we assessed CD40/CD40L expression by flow cytometrics assay in these groups of patients. RESULTS AND DISCUSSION: Our results indicate that IL-18 and nitrite levels were higher in naive-active BD patients. Interestingly, this high production differed according to the clinical manifestations and was associated with an increased risk of mucocutaneous and vascular involvement. Concerning corticosteroid treated-active BD patients, no difference was observed in this production between each clinical subgroup. However, IFN-gamma levels increased in all categories of active patients. Interestingly, corticosteroid therapy reduced significantly these inflammatory mediators regardless of the clinical manifestations studied. In addition, the CD40/CD40L expression differed according to the clinical presentations. CONCLUSION: Collectively, our results suggest that concomitant high production of IL-18 and NO in naive-active BD patients is related to an increased risk of mucocutaneous lesions and vascular involvement. Moreover, the relationship between these two inflammatory markers could constitute a predictable tool of BD clinical presentations and an early factor of therapy efficiency. PMID- 29600487 TI - Lead poisoning and other human-related factors cause significant mortality in white-tailed eagles. AB - The white-tailed eagle (Haliaeetus albicilla) suffered a severe population decline due to environmental pollutants in the Baltic Sea area ca. 50 years ago but has since been recovering. The main threats for the white-tailed eagle in Finland are now often related to human activities. We examined the human impact on the white-tailed eagle by determining mortality factors of 123 carcasses collected during 2000-2014. Routine necropsy with chemical analyses for lead and mercury were done on all carcasses. We found human-related factors accounting for 60% of the causes of death. The most important of these was lead poisoning (31% of all cases) followed by human-related accidents (e.g. electric power lines and traffic) (24%). The temporal and regional patterns of occurrence of lead poisonings suggested spent lead ammunition as the source. Lead shot was found in the gizzards of some lead-poisoned birds. Scavenging behaviour exposes the white tailed eagle to lead from spent ammunition. PMID- 29600489 TI - Predictive visual search: Role of environmental regularities in the learning of context cues. AB - Repeatedly searching through invariant spatial arrangements in visual search displays leads to the buildup of memory about these displays (contextual-cueing effect). In the present study, we investigate (1) whether contextual cueing is influenced by global statistical properties of the task and, if so, (2) whether these properties increase the overall strength (asymptotic level) or the temporal development (speed) of learning. Experiment 1a served as baseline against which we tested the effects of increased or decreased proportions of repeated relative to nonrepeated displays (Experiments 1b and 1c, respectively), thus manipulating the global statistical properties of search environments. Importantly, probability variations were achieved by manipulating the number of nonrepeated (baseline) displays so as to equate the total number of repeated displays across experiments. In Experiment 1d, repeated and nonrepeated displays were presented in longer streaks of trials, thus establishing a stable environment of sequences of repeated displays. Our results showed that the buildup of contextual cueing was expedited in the statistically rich Experiments 1b and 1d, relative to the baseline Experiment 1a. Further, contextual cueing was entirely absent when repeated displays occurred in the minority of trials (Experiment 1c). Together, these findings suggest that contextual cueing is modulated by observers' assumptions about the reliability of search environments.

PMID- 29600491 TI - Telepsychiatry: an Innovative Approach to Addressing the Opioid Crisis. AB - The opioid epidemic faced by the USA is a complex public health crisis, with staggering loss of life and overwhelming social, health, and economic costs. Despite the rising need for medication-assisted treatment, individuals struggling with opioid use continue to face multiple barriers hindering their access to care, particularly in rural areas. Innovative approaches to enhance access to treatment are needed. Telepsychiatry has proven to be effective and economical across multiple settings and psychiatric diagnoses, including opioid use disorder. As the implementation of telepsychiatry continues to expand, this method of healthcare delivery offers significant opportunities to overcome several barriers to access patients with opioid use disorder face. While addressing the opioid crisis will require multifaceted efforts involving multiple stakeholders and different approaches, a comprehensive strategy must incorporate the adoption of telepsychiatry as an innovative approach to overcoming barriers to treatment and enhancing access to care. PMID- 29600492 TI - The effects of gene disruption of Kre6-like proteins on the phenotype of beta glucan-producing Aureobasidium pullulans. AB - Killer toxin resistant 6 (Kre6) and its paralog, suppressor of Kre null 1 (Skn1), are thought to be involved in the biosynthesis of cell wall beta-(1 -> 6)-D glucan in baker's yeast, Saccharomyces cerevisiae. The Deltakre6Deltaskn1 mutant of S. cerevisiae and other fungi shows severe growth defects due to the failure to synthesize normal cell walls. In this study, two homologs of Kre6, namely, K6LP1 (Kre6-like protein 1) and K6LP2 (Kre6-like protein 2), were identified in Aureobasidium pullulans M-2 by draft genome analysis. The Deltak6lp1, Deltak6lp2, and Deltak6lp1Deltak6lp2 mutants were generated in order to confirm the functions of the Kre6-like proteins in A. pullulans M-2. The cell morphologies of Deltak6lp1 and Deltak6lp1Deltak6lp2 appeared to be different from those of wild type and Deltak6lp2 in both their yeast and hyphal forms. The productivity of the extracellular polysaccharides, mainly composed of beta-(1 -> 3),(1 -> 6)-D-glucan (beta-glucan), of the mutants was 5.1-17.3% less than that of wild type, and the degree of branching in the extracellular beta-glucan of mutants was 14.5-16.8% lower than that of wild type. This study showed that the gene disruption of Kre6 like proteins affected the cell morphology, the productivity of extracellular polysaccharides, and the structure of extracellular beta-glucan, but it did not have a definite effect on the cell viability even in Deltak6lp1Deltak6lp2, unlike in the Deltakre6Deltaskn1 of S. cerevisiae.

AB - Forests are essential biomes for global biogeochemical cycles, and belowground microorganisms have a key role in providing relevant ecosystem services. To predict the effects of environmental changes on these ecosystem services requires a comprehensive understanding of how biotic and abiotic factors drive the composition of microbial communities in soil. However, microorganisms are not homogeneously distributed in complex environments such as soil, with different features affecting microbes at different extent depending on the niche they occupy. Indeed, this spatial heterogeneity hampers the extrapolation of microbial diversity study results from particular habitats to the ecosystem level, even if the resolution of the more recent studies has increased significantly after the standardization of high-throughput sequencing techniques. The present work intends to give a comprehensive view of the knowledge accumulated until date defining the more important drivers determining the structure of forest soil microbial communities from fine to continental scales. PMID- 29600494 TI - Duox2-induced innate immune responses in the respiratory epithelium and intranasal delivery of Duox2 DNA using polymer that mediates immunization. AB - Respiratory mucosa especially nasal epithelium is well known as the first-line barrier of air-borne pathogens. High levels of reactive oxygen species (ROS) are detected in in vitro cultured human epithelial cells and in vivo lung. With identification of NADPH oxidase (Nox) system of respiratory epithelium, the antimicrobial role of ROS has been studied. Duox2 is the most abundant Nox isoform and produces the regulated amount of ROS in respiratory epithelium. Duox2 derived ROS are involved in antiviral innate immune responses but more studies are needed to verify the mechanism. In respiratory epithelium, Duox2-derived ROS is critical for recognition of virus through families retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation-associated protein 5 (MDA5) at the early stage of antiviral innate immune responses. Various secreted interferons (IFNs) play essential roles for antiviral host defense by downstream cell signaling, and transcription of IFN-stimulated genes is started to suppress viral replication. Type I and type III IFNs are verified more responsible for influenza A virus (IAV) infection in respiratory epithelium and Duox2 is required to regulate IFN-related immune responses. Transient overexpression of Duox2 using cationic polymer polyethylenimine (PEI) induces secretion of type I and type III IFNs and significantly attenuated IAV replication in respiratory epithelium. Here, we discuss Duox2-mediated antiviral innate immune responses and the role of Duox2 as a mucosal vaccine to resist respiratory viral infection. PMID- 29600495 TI - A preliminary study of telemedicine for patients with hepatic glycogen storage disease and their healthcare providers: from bedside to home site monitoring. AB - BACKGROUND: The purpose of this project was to develop a telemedicine platform that supports home site monitoring and integrates biochemical, physiological, and dietary parameters for individual patients with hepatic glycogen storage disease (GSD). METHODS AND RESULTS: The GSD communication platform (GCP) was designed with input from software developers, GSD patients, researchers, and healthcare providers. In phase 1, prototyping and software design of the GCP has occurred. The GCP was composed of a GSD App for patients and a GSD clinical dashboard for healthcare providers. In phase 2, the GCP was tested by retrospective patient data entry. The following software functionalities were included (a) dietary registration and prescription module, (b) emergency protocol module, and (c) data import functions for continuous glucose monitor devices and activity wearables. In phase 3, the GSD App was implemented in a pilot study of eight patients with GSD Ia (n = 3), GSD IIIa (n = 1), and GSD IX (n = 4). Usability was measured by the system usability scale (SUS). The mean SUS score was 64/100 [range: 38-93]. CONCLUSIONS: This report describes the design, development, and validation process of a telemedicine platform for patients with hepatic GSD. The GCP can facilitate home site monitoring and data exchange between patients with hepatic GSD and healthcare providers under varying circumstances. In the future, the GCP may support cross-border healthcare, second opinion processes and clinical trials, and could possibly also be adapted for other diseases for which a medical diet is the cornerstone. PMID- 29600496 TI - Allogeneic hematopoietic cell transplantation in Farber disease. AB - BACKGROUND: Farber disease (FD) is a rare, lysosomal storage disorder caused by deficient acid ceramidase activity. FD has long been considered a fatal disorder with death in the first three decades of life resulting either from respiratory insufficiency as a consequence of airway involvement or from progressive neurodegeneration because of nervous system involvement. Peripheral symptoms associated with FD, including inflammatory joint disease, have been described to improve relatively rapidly after hematopoietic cell transplantation (HCT). AIMS: To evaluate the disease-specific status and limitations in the long-term follow up after HCT, investigate genotype/phenotype correlations and the benefit of allogeneic HCT in FD patients with nervous system involvement. PATIENTS AND METHODS: Transplant- and disease-related information of ten FD patients was obtained by using a questionnaire, physicians' letters and additional telephone surveys. ASAH1 gene mutations were identified to search for genotype/phenotype correlations. RESULTS: After mainly busulfan-based preparative regimens, all patients engrafted with one late graft loss. The inflammatory symptoms resolved completely in all patients. Abnormal neurologic findings were present pre transplant in 4/10 patients, post-transplant in 6/10 patients. Mutational analyses revealed new mutations in the ASAH1 gene and a broad diversity of phenotypes without a genotype/phenotype correlation. With a median follow-up of 10.4 years, overall survival was 80% with two transplant-related deaths. CONCLUSION: Allogeneic HCT leads to complete and persistent resolution of the inflammatory aspects in FD patients. It appears to have no beneficial effect on progression of nervous system involvement. New mutations in the acid ceramidase gene were identified. A genotype/phenotype correlation could not be established. PMID- 29600497 TI - The rendering of human phenotype and rare diseases in ICD-11. AB - ICD-11 (International Classification of Diseases, 11th Revision) is the next major revision of the ICD by the World Health Organization (WHO). ICD-11 differs dramatically from historical versions, as it is based on an underlying semantic network of terms and meaning, called the Foundation. To function as a mutually exclusive and exhaustive statistical classification, ICD-11 creates derivative linearizations from the network that is a monohierarchy with residual categories such as Not Elsewhere Classified. ICD-11 also introduces the widespread post coordination of terms, which allows for highly expressive representation of detailed patient descriptions. Phenotyping features are included in many subchapters or the signs and symptoms chapter. Composite phenotype descriptions of specific presentations or syndromes can be represented though post coordination. Rare diseases are well represented in the Foundation, though not all appear in the relatively shallow linearization hierarchies.

AB - Pollution and the eutrophication process are increasing in lake Yahuarcocha and constant water quality monitoring is essential for a better understanding of the patterns occurring in this ecosystem. In this study, key sensor locations were determined using spatial and temporal analyses combined with geographical information systems (GIS) to assess the influence of weather features, anthropogenic activities, and other non-point pollution sources. A water quality monitoring network was established to obtain data on 14 physicochemical and microbiological parameters at each of seven sample sites over a period of 13 months. A spatial and temporal statistical approach using pattern recognition techniques, such as cluster analysis (CA) and discriminant analysis (DA), was employed to classify and identify the most important water quality parameters in the lake. The original monitoring network was reduced to four optimal sensor locations based on a fuzzy overlay of the interpolations of concentration variations of the most important parameters. PMID- 29600499 TI - Isoflurane anesthesia does not affect spinal cord neurovascular coupling: evidence from decerebrated rats. AB - Neurological examination remains the primary clinical investigation in patients with spinal cord injury. However, neuroimaging methods such as functional magnetic resonance imaging (fMRI) are promising tools for following functional changes in the course of injury, disease and rehabilitation. However, the relationship between neuronal activity and blood flow in the spinal cord on which fMRI relies has been largely overlooked. The objective of this study was to examine neurovascular coupling in the spinal cord of decerebrated rats during electrical stimulation of the sciatic nerve with and without isoflurane anesthesia (1.2%). Local field potentials (LFP) and spinal cord blood flow (SCBF) were recorded simultaneously in the lumbosacral enlargement. Isoflurane did not significantly alter LFP (p = 0.53) and SCBF (p = 0.57) amplitude. Accordingly, neurovascular coupling remained comparable with or without isoflurane anesthesia (p = 0.39). These results support the use of isoflurane in rodents to investigate nociceptive functions of the spinal cord using fMRI. PMID- 29600500 TI - Incidence of dental traumatic injuries in children 0-4 years of age: a prospective study based on parental reporting. AB - AIM: To collect prospective information reported by parents regarding dental traumas occurring in children 6 months to 4 years of age, furthermore, to collect data on complications from the dental records. METHODS: The staff from the child health services distributed a questionnaire at the regular health check-up reviews for a number of age groups, i.e., 6, 12, 18, 24, 30, 36, and 42 months of age. The parents were to observe and register factors around dental trauma for the following 6-month period. The questionnaires (138) were returned, irrespective of any trauma having occurred or not. If a child was seeing a dentist (emergency visit), the diagnosis of trauma and later complications were collected from the dental records. RESULTS: There were 35 of 138 children experienced trauma (6-47 months of age). The half-year incidence of trauma in children 6 months to 4.0 years of age was between 12 and 48%. A total of 41 traumatic dental injuries (TDIs) were reported. Of these 24 occurred indoors. The most common reason for trauma was falling accidents. In 24 out of the 41 reported TDIs the children were not seen by a dentist in connection with the trauma. The reason was that the parents thought the trauma did not matter. CONCLUSIONS: The high incidence of TDIs reported in toddlers in this study indicates that there is an under-reporting of TDIs in previously reported studies. The research design used in the present study has an advantage and should be tested in further studies. PMID- 29600501 TI - Antibiotic distribution, risk assessment, and microbial diversity in river water and sediment in Hong Kong. AB - For the past fewer years, environment antibiotic residues have got more and more attention. The occurrence and distribution of eight common antibiotics, belonging to five classes, were determined in both water and sediment of eleven rivers of Hong Kong. The target antibiotics were found to be widely distributed. Sulfamethoxazole (n.d.-79.9 ng/L), sulfadimidine (n.d.-29.9 ng/L), and ofloxacin (n.d.-75.5 ng/L) were the dominant antibiotics in river water, with detection rates of 84.6, 76.9, and 69.2%, respectively. Tetracycline (n.d.-9.8 ng/g) was the dominant antibiotic in sediment, with a detection rate of 60%. The concentrations of all antibiotics in river water of Hong Kong were lower than which in various rivers of Europe, North America and Australia, as well as the Pearl River Basin of China. All sediment sites exhibited significant bacterial diversity. Gammaproteobacteria (0.08-12.7%) and Flavobacteria (0.14-14.1%) were the dominant bacterial classes in all sediments. The bacterial compositions varied between sites; areas polluted with high levels of antibiotics had rich and highly diverse bacterial communities. The environmental risk assessment determined that the antibiotics in 73.1% of the samples posed ecological risks to algae, and two samples posed low risks to invertebrates. Ofloxacin was the main contributor of risk to aquatic organisms, while the antibiotics in 11.5% of the samples posed resistance selection risks. The occurrence and distribution of eight common antibiotics, belonging to five classes, were widely distributed in Hong Kong. Sulfamethoxazole, sulfadimidine, and ofloxacin were the dominant antibiotics in river waters, Tetracycline was the dominant antibiotic in sediment. Areas polluted with high levels of antibiotics had rich and highly diverse bacterial communities. Antibiotics in 73.1% of the samples posed ecological risks, while the antibiotics in 11.5% of the samples posed resistance selection risks. PMID- 29600502 TI - Tracking the elusive 5' exonuclease activity of Chlamydomonas reinhardtii RNase J. AB - KEY MESSAGE: Chlamydomonas RNase J is the first member of this enzyme family that has endo- but no intrinsic 5' exoribonucleolytic activity. This questions its proposed role in chloroplast mRNA maturation. RNA maturation and stability in the chloroplast are controlled by nuclear-encoded ribonucleases and RNA binding proteins. Notably, mRNA 5' end maturation is thought to be achieved by the combined action of a 5' exoribonuclease and specific pentatricopeptide repeat proteins (PPR) that block the progression of the nuclease. In Arabidopsis the 5' exo- and endoribonuclease RNase J has been implicated in this process. Here, we verified the chloroplast localization of the orthologous Chlamydomonas (Cr) RNase J and studied its activity, both in vitro and in vivo in a heterologous B. subtilis system. Our data show that Cr RNase J has endo- but no significant intrinsic 5' exonuclease activity that would be compatible with its proposed role in mRNA maturation. This is the first example of an RNase J ortholog that does not possess a 5' exonuclease activity. A yeast two-hybrid screen revealed a number of potential interaction partners but three of the most promising candidates tested, failed to induce the latent exonuclease activity of Cr RNase J. We still favor the hypothesis that Cr RNase J plays an important role in RNA metabolism, but our findings suggest that it rather acts as an endoribonuclease in the chloroplast. PMID- 29600503 TI - Reproducibility and Validity of a Questionnaire Measuring Treatment Burden on Patients with Type 2 Diabetes: Diabetic Treatment Burden Questionnaire (DTBQ). AB - INTRODUCTION: To measure the burden of pharmacotherapy on patients with type 2 diabetes mellitus (T2DM), we developed the Diabetes Treatment Burden Questionnaire (DTBQ), a patient-administered questionnaire composed of 18 questions, and evaluated its reproducibility and validity. METHODS: We enrolled 240 patients with T2DM under pharmacotherapy over 20 years of age at seven institutes in Japan. Their physicians filled out report forms on patient backgrounds, and the patients answered both the DTBQ and the Diabetes Treatment Satisfaction Questionnaire (DTSQ). For evaluation of reproducibility, 48 of the enrolled subjects completed a 2nd DTBQ at home after leaving the medical institutes. RESULTS: Statistical analyses were performed for two sets of subjects, the validity analysis set (N = 236) and the reproducibility analysis set (N = 47). Factor analysis found a simple structure in the DTBQ item scores using a three-factor model with varimax rotation; the three subscales were designated as "implementation burden", "flexibility burden", and "blood glucose control burden". All intraclass correlation coefficients for the subscale scores were 0.8 or higher, indicating high reproducibility. Negative correlations were observed between the DTSQ satisfaction score and the DTBQ subscale scores. Moreover, as the dosing frequency of diabetic medicines increased, the DTBQ total score (total burden score) also became higher. Likewise, expected associations were observed between patient backgrounds and DTSQ scores. CONCLUSION: The DTBQ has adequate reproducibility and validity as a measurement scale for treatment burden on T2DM patients.

PMID- 29600505 TI - The Economic Burden of Insulin-Related Hypoglycemia in Adults with Diabetes: An Analysis from the Perspective of the Italian Healthcare System. AB - INTRODUCTION: The aim of this analysis was to estimate the cost of insulin related hypoglycemia in adult patients with diabetes in Italy using the Local Impact of Hypoglycemia Tool (LIHT), and to explore the effect of different hypoglycemia rates on budget impact. METHODS: Direct costs and healthcare resource utilization were estimated for severe and non-severe hypoglycemic episodes in Italy and applied to the population of adults with type 1 diabetes (T1DM) and type 2 diabetes (T2DM) and their corresponding hypoglycemia episode rates (0.49 severe and 53.3 non-severe episodes per year for T1DM, and 0.09 severe and 9.3 non-severe episodes per year for T2DM). Uncertainty around model inputs was explored through sensitivity and scenario analyses. RESULTS: The direct cost of insulin-related hypoglycemia in Italy is estimated at ?144.7 million per year, with ?65 million attributable to severe episodes and ?79.6 million due to non-severe episodes. The total cost of hypoglycemia is approximately 1.7-fold higher for T2DM (?91.7 million) than for T1DM (?53 million). The cost of a hypoglycemic episode ranges from ?4.59 for a non-severe event where additional self-monitoring of blood glucose (SMBG) testing is the only cost incurred, to ?5790.59 for a severe event that also requires an ambulance, A&E, hospitalization, and a visit to a diabetes specialist. A reduction in hypoglycemia event rates could result in substantial cost savings; for example, a 20% reduction in severe and non-severe hypoglycemia rates could result in a saving of ?47,769 per general population of 100,000 people. CONCLUSIONS: The LIHT highlights the substantial economic burden of insulin related hypoglycemia in Italy, particularly with regards to non-severe hypoglycemia, an aspect of hypoglycemia that is often overlooked. This analysis may aid healthcare decision-making by allowing the costs of insulin therapies or diabetes self-management programs to be balanced with the savings provided by reductions in hypoglycemia.

AB - INTRODUCTION: Patients with type 2 diabetes mellitus (T2DM) are clinically heterogeneous in terms of disease severity, treatment, and comorbidities, potentially resulting in differential diabetic nephropathy (DN) progression courses. In this exploratory study we used latent class analysis (LCA) to identify patient groups with distinct clinical profiles of T2DM severity and explored the association between disease severity, DN progression or reversal, and healthcare resource use (HRU) and costs. METHODS: Latent class analysis was used to group adults with >= 2 medical claims with a diagnosis of T2DM and >= 2 urine albumin tests within the Truven MarketScan database (2004-2014), based on T2DM-related complications, comorbidities, and therapies. DN severity categories (normoalbuminuria, moderately increased albuminuria, and severely increased albuminuria) were determined based on urine albumin measure. The risks of DN progression and reversal (change to a more/less severe DN category) were compared among all identified latent classes using Kaplan-Meier analyses and log-rank tests. All-cause and DN-related costs and HRU were assessed and compared during the study period among the identified latent classes. RESULTS: Four clinically distinct profiles were identified among the 23,235 eligible patients: low comorbidity/low treatment (46.5%), low comorbidity/high treatment (29.0%), moderate comorbidity/high insulin use (9.7%), and high comorbidity/moderate treatment (14.8%). The 5-year DN progression rates for these clinically distinct profiles were 11.8, 18, 16.5, and 27.7%, respectively. Compared with the low comorbidity/low treatment group, all other groups were associated with an increased risk of DN progression (all p < 0.001). Increasing comorbidity was significantly associated with higher all-cause and DN-related HRU and costs, primarily driven by higher pharmacy and inpatient costs. CONCLUSION: Patients with T2DM who have more comorbidities experienced higher rates of DN progression and HRU and incurred higher healthcare costs compared with patients with low comorbidity profiles. Future prospective studies are needed to confirm the significance of these groups on DN progression, HRU, and costs. FUNDING: Takeda Development Center Americas, Inc. PMID- 29600506 TI - Prediabetes Directly Deteriorates into Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic Syndrome Triggered by Acute Pancreatitis: A Case Report Illustrating a "Chicken and Egg" Paradigm in Ketosis-Prone Diabetes. AB - INTRODUCTION: Diabetic crises occur most often in patients with type 1 diabetes and occasionally in type 2 diabetes, especially under stressful conditions. However, a diabetic crisis occurring directly from prediabetes is an unusual phenomenon. CASE REPORT: A 45-year-old woman presented with postprandial left upper quadrant abdominal pain, nausea, and vomiting. She had a past medical history of prediabetes with impaired fasting glucose and HbA1c 6.4%. On admission, routine laboratory tests showed high anion gap metabolic acidosis (pH 6.92), anion gap 41 mmol/L, blood glucose 931 mg/dL, beta-hydroxybutyrate 28 mmol/L, and calculated effective osmolarity 322 mOsm/kg; she was diagnosed with diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS), and DKA-related abdominal pain. Later, the patient was found to have elevated lipase and amylase, and diagnosed with acute pancreatitis. Since DKA can induce abdominal pain and nonspecific lipase elevation, both of which are characteristics of acute pancreatitis, while acute pancreatitis can conversely trigger DKA, there exists a "chicken and egg" paradigm. Therefore, the differential diagnosis is discussed. CONCLUSION: It is important to differentiate DKA from concomitant causes of abdominal pain to avoid missing the underlying etiology, which can be the trigger for DKA. During diabetic crises, treating the underlying trigger is just as important as managing metabolic derangements in order to achieve favorable outcomes; meanwhile, managing acute pancreatitis associated hyperglycemia can promote recovery. Additionally, diabetic crisis that directly evolves from prediabetes illustrates an atypical form of diabetes called ketosis-prone diabetes; we briefly discuss its clinical characteristics, classification, and follow-up. PMID- 29600507 TI - Probability of Achieving Glycemic Control with Basal Insulin in Patients with Type 2 Diabetes in Real-World Practice in the USA. AB - INTRODUCTION: Basal insulin (BI) plays an important role in treating type 2 diabetes (T2D), especially when oral antidiabetic (OAD) medications are insufficient for glycemic control. We conducted a retrospective, observational study using electronic medical records (EMR) data from the IBM(r) Explorys database to evaluate the probability of achieving glycemic control over 24 months after BI initiation in patients with T2D in the USA. METHODS: A cohort of 6597 patients with T2D who started BI following OAD(s) and had at least one valid glycated hemoglobin (HbA1c) result recorded both within 90 days before and 720 days after BI initiation were selected. We estimated the changes from baseline in HbA1c every 6 months, the quarterly conditional probabilities of reaching HbA1c < 7% if a patient had not achieved glycemic control prior to each quarter (Q), and the cumulative probability of reaching glycemic control over 24 months. RESULTS: Our cohort was representative of patients with T2D who initiated BI from OADs in the USA. The average HbA1c was 9.1% at BI initiation, and decreased robustly (1.5%) in the first 6 months after initiation with no further reductions thereafter. The conditional probability of reaching glycemic control decreased rapidly in the first year (26.6% in Q2; 17.6% in Q3; 8.6% in Q4), and then remained low (<= 6.1%) for each quarter in the second year. Cumulatively, about 38% of patients reached HbA1c < 7% in the first year; only approximately 8% more did so in the second year. CONCLUSION: Our study of real-world data from a large US EMR database suggested that among patients with T2D who initiated BI after OADs, the likelihood of reaching glycemic control diminished over time, and remained low from 12 months onwards. Additional treatment options should be considered if patients do not reach glycemic control within 12 months of BI initiation. FUNDING: Sanofi Corporation.

AB - This paper describes a unique treatment program for complex pediatric illness. The Hasbro Children's Partial Hospital Program uses a family systems orientation, integrated care, and a partial hospital setting to treat children with a wide range of pediatric illnesses that have failed outpatient and inpatient treatments. We have treated more than 2000 children with at least 80 different ICD-9 diagnoses. The multidisciplinary treatment team functions as a meta-family for children and their families who present with illness and family beliefs that impede successful outcomes with standard care. The three features: family systems orientation, integrated care, and partial hospital setting, hopefully interact to create an environment that helps families expand and modify their explanatory models regarding participating in effective medical care. The goal of treatment is for both children and their parents to feel empowered to take control of the illness. Parents completing standardized measures at intake describe their children and families as experiencing significant emotional distress, low levels of general family functioning, and poor quality of life. Although the children are described as having distinct behavioral differences, the families are described as responding to the experience of a seriously ill child in similar ways. A treatment program that addresses the noncategorical aspects of how families respond to illness while addressing the specific diseases of the children can allow children and their families to respond favorably to treatment.

PMID- 29600511 TI - Increased cerebral blood flow on arterial spin labeling magnetic resonance imaging can localize to seizure focus in newborns: A report of 3 cases. AB - Arterial spin labeling (ASL) magnetic resonance imaging (MRI) can assess cerebral blood flow (CBF) without using radiolabeled tracers. It is unknown whether regional increases in CBF on ASL MRI correlate with seizure location in newborns. We report 3 newborns with focal seizures localized on continuous video electroencephalogram (cEEG), anatomical brain MRI, and ASL MRI. Each patient underwent pseudocontinuous ASL with segmented 3-dimensional fast spin echo readout as part of standard care. Case 1 is a term male infant presenting with left temporal status epilepticus and recurrent cEEG seizures from an idiopathic large left intraventricular hemorrhage. ASL images demonstrated left mesial temporal lobe increased CBF. Case 2 is a late preterm male infant presenting with recurrent cEEG seizures due to focal right megalencephaly. Ictal EEG and ASL images coincided with the focal dysplasia. Case 3 is a dysmorphic term female infant with nonconvulsive partial status epilepticus identified by focal increased CBF of the left temporal lobe on ASL images. The area of increased CBF was within an area of extensive left hemisphere dysplasia. To our knowledge, this is the first report of regional increases in CBF on ASL MRI correlating with ictal cEEG in newborns. PMID- 29600512 TI - Prevalence of spinal abnormalities in Chinook salmon smolt and influence of early rearing temperature and growth rates. AB - Spinal abnormalities can be detected at harvest in around 40% of farmed Chinook salmon in New Zealand. However, whether these abnormalities are present in smolt is unknown. Radiographs of 3,736 smolt were taken immediately prior to transfer to sea water and evaluated for fusions, compressions, vertical shifts, and lordosis, kyphosis and/or scoliosis (LKS). The survey included smolt from two different chilling strategies that had been graded into slow- or fast-growing fish. Overall, 4.34% of Chinook salmon smolt had at least one spinal abnormality, similar to the rates of reported in Atlantic salmon smolt. The rate of abnormality was significantly higher in faster-growing fish. Fusions were most common with 2.68% of smolt affected. Smolt subjected to longer chilling times had lower rates of fusions. Compressions and vertical shifts were both observed in 1.31% of smolt. Although LKS is the most common abnormality of harvested fish, LKS was detected in just five smolt. The results suggest that some fusions in harvest fish have developed at the time of seawater transfer while LKS develops late in the production cycle. Overall, spinal abnormalities are uncommon in Chinook salmon smolt and may be influenced by chilling times and growth rates. PMID- 29600513 TI - Alcohol hangover impacts learning and reward processing within the medial-frontal cortex. AB - It is common knowledge that alcohol intoxication impairs motor coordination, judgment, and decision making. Indeed, an abundance of literature links intoxication to impaired cognitive control that leads to accidents and injury. A broadening body of research, however, suggests that the impact of alcohol may continue beyond the point of intoxication and into the period of alcohol hangover. Here, we examined differences in the amplitude of reward positivity-a component of the human ERP associated with learning-between control and hangover participants. During performance of a learnable gambling task, we found a reduction in the reward positivity during alcohol hangover. Additionally, participants experiencing alcohol hangover demonstrated reduced performance in the experimental task in comparison to their nonhangover counterparts. Our results suggest that the neural systems that underlie performance monitoring and reward-based learning are impaired during alcohol hangover. PMID- 29600514 TI - Ambient aerosol increases minimum leaf conductance and alters the aperture-flux relationship as stomata respond to vapor pressure deficit (VPD). AB - Aerosols are important components of the global plant environment, with beneficial and deleterious impacts. The direct effects of aerosol deposition on plant-water relationships remain poorly characterized but potentially important. Vicia faba was grown in ambient urban air and in the same air with aerosol excluded, in a moderately polluted environment using two exposure protocols. Simultaneous measurement of gas exchange and stomatal pore aperture was combined with leaf dehydration kinetics and microscopic evaluation of leaf wetness formation and aerosol deposition patterns. The ambient aerosol was shown to be hygroscopic. Aerosol exposure increased minimum leaf conductance, shown by dehydration kinetics, and nocturnal water vapor flux, shown by dark-adapted gas exchange. Aerosol exposure decreased stomatal apertures at each level of vapor pressure deficit (VPD) and increased stomatal conductance at comparable levels of aperture. Overall, these effects were modest, and largest when stomata were wide open. The uncoupling of conductance (flux-based) from aperture (directly measured microscopically) implies that aerosol-induced water loss is not fully under stomatal control. This reduces drought tolerance and may provide a mechanism by which deposited aerosol plays a direct role in stomatal response to VPD. PMID- 29600516 TI - Obliquely-arranged double skin paddles: A novel design to reconstruct extensive head and neck defects with a single fibula or peroneal flap. AB - OBJECTIVE: To reconstruct extensive head and neck defects usually necessitates double free flaps, which require a time-and-manpower-consuming surgical procedure. We present using a single fibula or peroneal flap with the novel design of obliquely-arranged double skin paddles to reconstruct an extensive head and neck defect. METHODS: From 1998 to 2016, eight patients with the age of 52.25 (35-71) years old had extensive head and neck defects after oral cancer ablation. All of the defects were through and through with the size of 16.25 (12-24) cm * 8.8 (4.5-11) cm. Six of the defects were due to buccal cancer. One was due to tongue cancer, and another one was due to gingiva cancer. All the defects were reconstructed with obliquely-arranged double-paddle free fibula or peroneal flaps. The long axis of the skin paddles was arranged at certain angle (30-45 degrees) to the long axis of lower leg, and the two separate skin paddles were used as the form of island flaps by isolating the cutaneous perforators to create a true chimeric flap. RESULTS: The skin paddle sizes were 14 cm * 3 cm-24 cm * 11 cm and 9.5 cm * 4.5 cm-13 cm * 8 cm. The average length of harvested fibula was 19 (10-30) cm. All of the eight flaps survived without obvious donor site morbidity. One patient had partial skin necrosis over recipient site, requiring surgical debridements and closure. One patient had superficial necrosis over the edge of outer skin paddle, which healed spontaneously. After the follow-up periods of 1 month to 3 year and 8 months, two patients died of sepsis. Six of them could resume soft diet and had no saliva drooling. The remaining two remained nasogastric diet and had saliva drooling. CONCLUSION: With the design of obliquely-arranged double paddles, we may maximize the harvested skin area of lateral lower leg to reconstruct an extensive head and neck defect with a single free flap.

AB - Atopic dermatitis is the most common chronic skin disease, and it primarily affects children. Although atopic dermatitis (AD) has the highest effect on burden of skin disease, no high-level studies have defined optimal therapy for severe disease. Corticosteroids have been used to treat AD since the 1950s and remain the only systemic medication with Food and Drug Administration approval for this indication in children, despite published guidelines of care that recommend against this option. Several clinical trials with level 1 evidence have supported the use of topical treatments for mild to moderate atopic dermatitis in adults and children, but these trials have had little consistency in protocol design. Consensus recommendations will help standardize clinical development and trial design for children. The Food and Drug Administration issues guidance documents for industry as a source for "the Agency's current thinking on a particular subject." Although they are nonbinding, industry considers these documents to be the standard for clinical development and trial design. Our consensus group is the first to specifically address clinical trial design in this population. We developed a draft guidance document for industry, Developing Drugs for Treatment of Atopic Dermatitis in Children (>=3 months to <18 years of age). This draft guidance has been submitted to the Food and Drug Administration based on a provision in the Federal Register (Good Guidance Practices).

AB - OBJECTIVE: To determine the impact of length of stay among homeless men in faith based residential addictions recovery on physical activity, depression, self esteem, and nicotine dependence. DESIGN AND SAMPLE: A time series design was utilized to measure changes in the four quality measures at program entry and at 3, 6, and 9 months following admission. The sample consisted of 175 homeless residents enrolled in a faith-based residential recovery program. MEASURES: Paired t tests were used to determine the change in average instrument response from admission to each follow-up period. Analysis of variance (ANOVA) and Tukey posthoc tests were used to assess for differences in length of stay between demographic variables. RESULTS: Statistically significant improvements were noted in self-esteem and depressive symptomatology at 3 and 6 months following admission and in physical activity levels at 3 months following admission. Nicotine dependence scores declined at 3 and 6 months but were not statistically significant. CONCLUSION: Time spent in this faith-based spiritual recovery program had a significant impact on depression, self-esteem, and physical activity. Recommendations for future study include conducting research to analyze the relationship between distinct program elements and quality indicators and comparing faith-based programs to other similar programs and to publicly funded secular recovery programs.

AB - Nitrogen (N) availability is increasing dramatically in many ecosystems, but the influence of elevated N on the functioning of arbuscular mycorrhizal (AM) fungi in natural ecosystems is not well understood. We measured AM fungal community structure and mycorrhizal function simultaneously across an experimental N addition gradient in an alpine meadow that is limited by N but not by phosphorus (P). AM fungal communities at both whole-plant-community (mixed roots) and single plant-species (Elymus nutans roots) scales were described using pyro-sequencing, and the mycorrhizal functioning was quantified using a mycorrhizal-suppression treatment in the field (whole-plant-community scale) and a glasshouse inoculation experiment (single-plant-species scale). Nitrogen enrichment progressively reduced AM fungal abundance, changed AM fungal community composition, and shifted mycorrhizal functioning towards parasitism at both whole-plant-community and E. nutans scales. N-induced shifts in AM fungal community composition were tightly linked to soil N availability and/or plant species richness, whereas the shifts in mycorrhizal function were associated with the communities of specific AM fungal lineages. The observed changes in both AM fungal community structure and functioning across an N enrichment gradient highlight that N enrichment of ecosystems that are not P-limited can induce parasitic mycorrhizal functioning and influence plant community structure and ecosystem sustainability.

AB - The soybean pod borer [SPB; Leguminivora glycinivorella (Mats.) Obraztsov] is a major soybean pest in northeastern Asia. A useful method for addressing this problem is the generation of transgenic plants producing double-stranded RNA (dsRNA) that target essential insect genes. In this study, we confirmed that 18S ribosomal RNA is critical for SPB development. Downregulated Spb18S expression induced by dsRNA injection increased larval mortality rates and resulted in early pupation. We also assessed whether Spb18S is silenced in SPB larvae fed on transgenic soybean expressing Spb18S dsRNA. Transgenic plants downregulated Spb18S expression levels and second-instar larval survival rates. Moreover, such plants were less damaged by SPB larvae than control plants under field conditions. PMID- 29600520 TI - Identification of differentially regulated deceitful proteins in SH-SY5Y cells engineered with Tet-regulated protein expression system. AB - Tetracycline regulated protein expression in mammalian cells is a powerful tool to predict the physiological function, cellular localization, and stability of a protein. In addition, to predict metabolic networks affected by the expression of wild-type or mutant forms of proteins, researchers generally produce a single mammalian cell clone that can express the protein of interest under tetracycline control and study the changes occurring in overall proteome before and after expression of a protein of interest. One limitation of tetracycline regulated clonal cell creation, however, is that it sometimes creates clones with changed protein levels even without the expression of the protein of interest due to the nonspecific insertion of the gene encoding the protein of interest into the genome or disruption of a metabolic pathway due to insertional silencing or activation. The aim of this study was to demonstrate the limitation of tetracycline regulated gene expression by creating clonal cell lines expressing the wild-type or the mutant forms of Fat mass and obesity-associated protein. Comparative proteome analysis of the protein extracts by two-dimensional gel electrophoresis coupled to MALDI-TOF/TOF revealed the presence of eight proteins subjected to differential regulation even in the absence of induction. The identified proteins were 14-3-3 protein Epsilon, Vimentin, Heterogeneous nuclear ribonucleoprotein K, Tubulin beta-2C chain, Heat shock protein HSP 90-alpha, Heat shock protein HSP 90-beta, Alpha-enolase, TATA-binding protein-associated factor 2N. An ultimate care should be taken to prevent reporting of deceitful proteins generated from studies utilizing tetracycline regulated gene expression systems. PMID- 29600521 TI - Phytosomal-curcumin antagonizes cell growth and migration, induced by thrombin through AMP-Kinase in breast cancer. AB - Here we explored the antitumor-activity of novel-formulated-form of curcumin (phytosomal-encapsulated-curcumin) or in combination with 5-FU in breast cancer. The antiproliferative activity was assessed in 2D and 3-dimensional cell-culture model. The migratory-behaviors of the cells were determined by migration assay. The expression levels of CyclinD1,GSK3a/b, P-AMPK, MMP9, and E-cadherin were studied by qRT-PCR and/or Western blotting. The anti-inflammatory of nano curcumin was assessed, while antioxidant activity was evaluated by malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and total thiols (T-SH). To understand dynamic behavior of genes, we reconstructed a Boolean network, while the robustness of this model was evaluated by Hamming distance. phytosomal-curcumin suppressed cell-growth followed by tumor-shrinkage in 3D model through perturbation of AMP-activated protein kinase. Curcumin reduced the invasiveness of MCF-7 through perturbation of E-cadherin. Moreover, phytosomal-curcumin inhibited the tumor growth in xerograph model. Histological staining of tumor tissues revealed vascular disruption and RBC extravasation, necrosis, tumor stroma, and inflammation. Co-treatment of curcumin and 5-FU reduced the lipid-peroxidation and increased MDA/SOD level. Of note, curcumin reduced cyclinD-expression in breast cancer cell treated with thrombin, and activates AMPK in a time-dependent manner. Also suppression of AMPK abrogated inhibitory effect of phytosomal-curcumin on thrombin-induced cyclin D1 over expression, suggesting that AMPK is essential for anti-proliferative effect of this agent in breast cancer. Our finding demonstrated that phytosomal-curcumin antagonizes cell growth and migration, induced by thrombin through AMP-Kinase in breast cancer, supporting further-investigations on the therapeutic potential of this novel anticancer agent in treatment of breast cancer. PMID- 29600522 TI - Studies on the effects of LPS, beta-glucan and metabolic inhibitors on the respiratory burst and gene expression in Atlantic salmon macrophages. AB - Reactive oxygen species (ROS) production in macrophage-like cells is induced as an antimicrobial defence against invading pathogens. In this study, we have explored how different stimuli and metabolic inhibitors affect the level of respiratory burst in Atlantic salmon (Salmo salar L.) head kidney macrophage-like cells. Cells stimulated in vitro by bacterial lipopolysaccharide (LPS) and beta glucan showed increased production of ROS compared to unstimulated cells. Both stimulation and costimulation by curdlan (beta-glucan) induced a higher production of ROS compared to stimulation and costimulation by LPS. Metabolic inhibitors co-incubated with the stimulants did not, in most cases, perturb the level of ROS generation in the salmon macrophage-like cells. The NAD+ content as well as the NAD+ /NADH ratio increased in curdlan and LPS + curdlan-stimulated cells compared to control cells, which indicated increased metabolic activity in the stimulated cells. Supporting these findings, gene analysis using real-time quantitative PCR showed that arginase-1 and IL-1beta genes were highly expressed in the stimulated cells. PMID- 29600523 TI - Grading of meningeal solitary fibrous tumors/hemangiopericytomas: analysis of the prognostic value of the Marseille Grading System in a cohort of 132 patients. AB - The finding that meningeal solitary fibrous tumors (SFTs) and meningeal hemangiopericytomas (HPCs) are both characterized by NAB2-STAT6 gene fusion has pushed their inclusion in the WHO 2016 Classification of tumors of the central nervous system (CNS) as different manifestations of the same entity. Given that the clinical behavior of the CNS SFT/HPC spectrum ranges from benign to malignant, it is presently unclear whether the grading criteria are still adequate. Here, we present the results of a study that analyzed the prognostic value of an updated version of the Marseille Grading System (MGS) in a retrospectively assembled cohort of 132 primary meningeal SFTs/HPCs with nuclear overexpression of STAT6. The median patient follow-up was 64 months (range 4-274 months); 73 cases (55%) were MGS I, 50 cases (38%) MGS II and 9 cases (7%) were MGS III. Progression-free survival (PFS) and disease-specific survival (DSS) were investigated using univariate analysis: the prognostic factors for PFS included MGS, extent of surgery, radiotherapy, chemotherapy and mitotic activity >=5/10 high-power field (HPF). Moreover, MGS, radiotherapy, mitotic activity >=5/10 HPF, and necrosis were the prognostic factors measured for DSS. In multivariate analysis, extent of surgery, mitotic activity >=5/10 HPF, MGS I and MGS III were the independent prognostic factors measured for PFS while necrosis, MGS III and radiotherapy were the independent prognostic factors for DSS. In conclusion, our results show that assessing the malignancy risk of SFT/HPC should not rely on one single criterion like mitotic activity. Therefore, MGS is useful as it combines the value of different criteria. In particular, the combination of a high mitotic activity and necrosis (MGS III) indicates a particularly poor prognosis. PMID- 29600524 TI - Symptom experiences in patients with advanced pancreatic cancer as reported during healthcare encounters. AB - Symptom management is one of the primary goals of care for advanced pancreatic cancer (APC) patients. The purpose of this study was to examine recorded healthcare encounters to better understand the symptom experiences of APC patients as told to healthcare providers (HCP). In this qualitative descriptive study, content analysis was used to analyze 37 transcripts of audio-recorded, naturally occurring encounters among APC patients, caregivers, and HCP. Transcripts were drawn from a larger randomized controlled study, which recruited advanced cancer patients and caregivers across the United States. Findings revealed that APC patients and caregivers experienced multiple troubling symptoms. Thirty-seven APC patients and 34 caregivers discussed 10 types of symptoms: pain, fatigue, abnormal bowel movements, decreased appetite, nausea and vomiting, sleeping problems, neurological problems, skin problems, psychological distress, and taste changes. The patients and caregivers discussed various aspects of the symptoms, including the nature of the symptoms, how the symptoms affected their lives, and the way they managed symptoms. Some symptoms were described as severe, life-changing, and highly distressing. HCP should be attuned to the wide variety of ways in which APC patients experience, manage, and live with symptoms. A systematic approach to address symptoms during encounters may improve care and efficiency. PMID- 29600525 TI - Thiacloprid-induced toxicity influenced by nutrients: Evidence from in situ bioassays in experimental ditches. AB - Many studies show that neonicotinoid insecticides cause toxicity to aquatic invertebrates. Some studies report that insecticide toxicity may differ in combination with other agrochemicals under realistic field conditions. To explore such altered toxicity further, we aimed to determine the single and combined effects of environmentally relevant levels of the neonicotinoid thiacloprid and nutrients on different endpoints of 4 aquatic invertebrate species. Animals were exposed to these agrochemicals using a caged experiment within experimental ditches. We observed thiacloprid-induced toxicity for 2 crustaceans, Daphnia magna and Asellus aquaticus, and for 1 out of 2 tested insect species, Cloeon dipterum. We observed no toxic effects for Chironomus riparius at the time weighted average test concentration of 0.51 MUg thiacloprid/L. For D. magna, the observed toxicity, expressed as the lowest-observed-effect concentration (LOEC), on growth and reproduction was present at thiacloprid concentrations that were 2456-fold lower than laboratory-derived LOEC values. This shows that these species, when exposed under natural conditions, may exhibit neonicotinoid-induced toxic stress. Contrary to the low nutrient treatment, such toxicity was often not observed under nutrient-enriched conditions. This was likely attributable to the increased primary production that allowed for compensatory feeding. These findings warrant the inclusion of different feeding regimes in laboratory experiments to retrieve the best estimates of neonicotinoid-induced toxicity in the natural environment.

Fucosidases catalyze the removal of fucose residues, and have been correlated to different physiological and pathological processes, such as fertilization, cancer, fucosidosis, and digestion in molluscs and ticks. An alpha-l-fucosidase sequence was identified from the transcriptome and proteome from the midgut diverticula of the synanthropic spider Nephilingis cruentata. In this article, we describe the isolation of this alpha-l-fucosidase and the characterization of its activity using substrates and inhibitors demonstrating different specificities among fucosidases. The enzyme had a Km of 32 and 400 MUM for 4-methylumbelliferyl alpha l-fucopyranoside and 4-nitrophenyl alpha-l-fucopyranoside, respectively; and was unable to hydrolyze fucoidan. Nephilingis cruentata alpha-l-fucosidase was inhibited competitively by fucose and fuconojyrimycin. The fucosidase had two distinct pH optima even in the isolated form, due to oligomerization dependent on pH, as previously described to other fucosidases. Alignment and molecular homology modeling of the protein sequence with other fucosidases indicated that the active sites and catalytic residues were different, including residues involved in acid/base catalysis. Phylogenetic analysis showed, for the first time, gene-duplication events for fucosidases in Arachnida species. All these data reveal that studies on fucosidases in organisms distinct from bacteria, fungi, and humans are important.

AB - A novel type of multivalent and highly specific fluorescent hyperbranched glycopolymers h-P(GalEA-co-VBPT-co-BYMA) (hPGVB) is designed and prepared successfully via a facile "bottom-up" strategy. The acetylated hPGVB is prepared by one-pot reversible addition-fragmentation chain transfer (RAFT) copolymerization of acrylate-type galactose monomers AcGalEA and methacrylate type fluorescent monomers BYMA in presence of an inimer-type RAFT chain transfer agent. After deacetylation, the resulting amphiphilic hPGVB can self-assemble into stable nanoparticles in aqueous media, showing strong green fluorescence with relative high quantum yields and good photostability. The cell viability study indicates the excellent biocompatibility of the hPGVB fluorescent nanoparticles (FNPs) against HepG2 and NIH3T3 cells. More importantly, comparing with the galactose-free fluorescent hyperbranched polymers h-P(OEGMA-co-VBPT-co BYMA), hPEVB FNPs can be selectively internalized by asialoglycoprotein (ASGP) receptor-rich HepG2 cells, indicating their potential application in the bioimaging fields.

AB - Newly designed and prepared vanadium complexes bearing anionic pyrrole-based PNP type pincer and aryloxy ligands were found to work as effective catalysts for the direct conversion of molecular dinitrogen into ammonia and hydrazine under mild reaction conditions. This is the first successful example of vanadium-catalyzed dinitrogen reduction under mild reaction conditions. PMID- 29600530 TI - Does a blended learning environment suit advanced practice training for pharmacists in a Middle East setting? AB - OBJECTIVES: The transfer of pedagogies and instructional techniques outside their contexts of origin may not be always be suitable for intended learners. The aim of this study was to explore the experiences of Middle East pharmacists enrolled in advanced pharmacy practice courses delivered through a blended learning environment (BLE). METHODS: Seventeen students and graduates from a BLE in Qatar participated in focus group interviews. A topic guide was developed to elicit these pharmacists' perspectives on perceived barriers to completing the courses and facilitating factors for content engagement and overall satisfaction. Discussions were recorded, transcribed verbatim and text analysed using thematic content analysis. KEY FINDINGS: We identified three predominant themes in our analysis of these discussions: (1) relevance, (2) motivation and (3) communication. Participants favourably endorsed any programme aspect that linked with their workplace care responsibilities, but found it challenging to adapt to high-fidelity testing environments. The on-campus sessions were key for sustaining motivation and recommitting to time management and organisation with the distance-based content. Although these students expressed difficulty in understanding posted assignment instructions and feedback and occasionally faced technological issues, they were overwhelmingly satisfied with how the programme contributed to advancing their practice capabilities. CONCLUSIONS: Pharmacists enrolled in BLE advanced pharmacy practice courses in Qatar identified barriers and facilitators like those experienced by professional learners elsewhere. However, we found that instructional design and communication approaches merit some special consideration for Arab students for optimal engagement in BLE. PMID- 29600531 TI - From S,N-Heteroacene to Large Discotic Polycyclic Aromatic Hydrocarbons (PAHs): Liquid Crystal versus Plastic Crystalline Materials with Tunable Mechanochromic Fluorescence. AB - A novel type of discotic polycyclic aromatic hydrocarbon (PAH) based on an enlarged dibenzo[a,c]phenazine core has been developed. The large conjugated mesogenic core with increased dipole moment derived from S,N heteroatoms facilitates the formation of highly ordered columnar superstructures both in solution and bulk. Columnar mesophases, including liquid crystal (LC) and plastic crystal (PC) assemblies could form unprecedentedly based on the same PAH core. The cores are delicately modulated by the peripherical alkoxy chains. Both mesogens have mechanochromic fluorescent (MCF) character, which is also structure dependent and correlated with the different mesophase formation. For the first time, MCF properties can be realized in such a large conjugated mesogenic system. PMID- 29600532 TI - Sertoli cells for cell transplantation: pre-clinical studies and future perspectives. AB - Sertoli cells are located in the testes where they control several key functions in spermatogenesis. Over the past 30 years, Sertoli cells have been upgraded from a simple scaffold-like structural system to a dynamic functional system of intercellular support that delivers potent immunomodulatory and trophic factors. Since the discovery of new Sertoli cell secretory products, these cells have been utilized in experimental cell transplantation and co-transplantation protocols aimed at treating both chronic inflammatory and degenerative disorders. For these reasons, this work reviews the application of both naked and microencapsulated Sertoli cells used in cell transplantation studies of several chronic or autoimmune diseases such as diabetes mellitus, Laron dwarfism, and Duchenne muscular dystrophy and in studies aimed at the prevention of skin allograft rejection. PMID- 29600533 TI - Peptide-Based Scaffold for Nitric Oxide Induced Differentiation of Neuroblastoma Cells. AB - Nitric oxide is a gaseous messenger involved in neuronal differentiation, development and synaptogenesis, in addition to many other physiological functions. Therefore, it is imperative to maintain an optimal nitric oxide concentration to ensure its biochemical function. A sustained nitric oxide releasing scaffold, which supports neuronal cell differentiation, as determined by morphometric analysis of neurite outgrowth, is described. Moreover, the effect of nitric oxide on the neuroblastoma cell line was also confirmed by immunofluorescent analysis of neuronal nuclear protein (NeuN), specific neuronal marker and neurofilament (NF) protein, which revealed a significant increase in their expression levels, in comparison with undifferentiated cells. PMID- 29600534 TI - Effect of Mitomycin C on recurrence of plantar fibromas. AB - Although certainly not the first line treatment for plantar fibromas, surgical resection is a treatment option for some patients with have failed exhaustive non surgical treatment. The use of topical Mitomycin C has been recently shown to reduce the recurrence rate of other fibrous lesions. The purpose of this study was to determine the impact of topical application of Mitomycin C on recurrence rate of plantar fibromas. A retrospective analysis was done from a prospectively gathered database with a total 50 consecutive patients over a 16-month study period. The control group (n = 29) consisted of patients who underwent only surgical resection, while the study group (n = 21) consisted of patients who underwent surgical resection with adjuvant therapy using Mitomycin C. The primary endpoint was local recurrence after the procedure. Secondary end points included complications and toxicity associated with this medication. No patients were lost to follow up. Of the 29 patients in the control group, there were 17 patients (17/29, 58.6%) had recurrence of the plantar fibroma at a mean follow-up of 9.1 months. In contrast, in the experimental study group, all patients were free from local recurrence. No complications or side effects were associated with Mitomycin C use. The results demonstrate that the topical application of Mitomycin C to the tumor bed after surgical resection of plantar fibromas reduced the recurrence rate. (c) 2018 Orthopaedic Research Society.

PMID- 29600535 TI - Nematode-associated microbial taxa do not correlate with host phylogeny, geographic region or feeding morphology in marine sediment habitats. AB - Studies of host-associated microbes are critical for advancing our understanding of ecology and evolution across diverse taxa and ecosystems. Nematode worms are ubiquitous across most habitats on earth, yet little is known about host associated microbial assemblages within the phylum. Free-living nematodes are globally abundant and diverse in marine sediments, with species exhibiting distinct buccal cavity (mouth) morphologies that are thought to play an important role in feeding ecology and life history strategies. Here, we investigated patterns in marine nematode microbiomes, by characterizing host-associated microbial taxa in 281 worms isolated from a range of habitat types (deep-sea, shallow water, methane seeps, Lophelia coral mounds, kelp holdfasts) across three distinct geographic regions (Arctic, Southern California and Gulf of Mexico). Microbiome profiles were generated from single worms spanning 33 distinct morphological genera, using a two-gene metabarcoding approach to amplify the V4 region of the 16S ribosomal RNA (rRNA) gene targeting bacteria/archaea and the V1 V2 region of the 18S rRNA gene targeting microbial eukaryotes. Contrary to our expectations, nematode microbiome profiles demonstrated no distinct patterns either globally (across depths and ocean basins) or locally (within site); prokaryotic and eukaryotic microbial assemblages did not correlate with nematode feeding morphology, host phylogeny or morphological identity, ocean region or marine habitat type. However, fine-scale analysis of nematode microbiomes revealed a variety of novel ecological interactions, including putative parasites and symbionts, and potential associations with bacterial/archaeal taxa involved in nitrogen and methane cycling. Our results suggest that in marine habitats, free-living nematodes may utilize diverse and generalist foraging strategies that are not correlated with host genotype or feeding morphology. Furthermore, some abiotic factors such as geographic region and habitat type do not appear to play an obvious role in structuring host-microbe associations or feeding preferences. PMID- 29600536 TI - Copaiba oil enhances in vitro/in vivo cutaneous permeability and in vivo anti inflammatory effect of celecoxib. AB - OBJECTIVES: The aim of this article was to use copaiba oil (C.O) to improve skin permeability and topical anti-inflammatory activity of celecoxib (Cxb). METHODS: Formulations containing C.O (1-50%) were associated with Cxb (2%). In vitro skin permeability studies were conducted using porcine ear skin. Histological analysis of the hairless mice skin samples after application of formulations was achieved with the routine haematoxylin/eosin technique. The anti-inflammatory activity was assessed using the AA-induced ear oedema mice model. KEY FINDINGS: The formulation containing 25% C.O promoted the highest levels of in vitro Cxb permeation through pig ear skin, retention in the stratum corneum (SC) and epidermis/dermis of pig ear skin in vitro (~5-fold) and hairless mice skin in vivo (~2.0-fold), as compared with the control formulation. At 25%, C.O caused SC disorganization and increased cell infiltration and induced angiogenesis without clear signs of skin irritation. The formulation added to 25% C.O as adjuvant inhibited ear oedema and protein extravasation by 77.51 and 89.7%, respectively, and that it was, respectively, 2.0- and 3.4-fold more efficient than the commercial diethylammonium diclofenac cream gel to suppress these inflammatory parameters. CONCLUSIONS: 25% C.O is a potential penetration enhancer for lipophilic drugs like Cxb that can improve cutaneous drug penetration and its anti-inflammatory activity.

AB - Hyper-immunoglobulin D syndrome is a rare autosomal-recessive autoinflammatory syndrome in which a mevalonate kinase deficiency results due to mutations of the mevalonate kinase gene. We report a case of an Asian male infant who was found to have hyper-immunoglobulin D syndrome in the absence of fever. His skin manifestations included cephalic pustulosis as well recurrent transient and fixed pink plaques and nodules on the face and extremities. Subsequent examination revealed hyper-immunoglobulin D syndrome with two novel allelic mutations in the mevalonate kinase gene: c.895G > A (p.D299N) and c.1168C > T (p.Q390). It is important for dermatologists to recognize the varied cutaneous presentations of hyper-immunoglobulin D syndrome because rapid diagnosis and treatment can significantly affect outcomes. PMID- 29600538 TI - SB-216763, a GSK-3beta inhibitor, protects against aldosterone-induced cardiac, and renal injury by activating autophagy. AB - Cardiovascular and renal inflammation induced by Aldosterone (Aldo) plays a pivotal role in the pathogenesis of hypertension and renal fibrosis. GSK-3beta contributes to inflammatory cardiovascular and renal diseases, but its role in Aldo-induced hypertension, and renal damage is not clear. In the present study, rats were treated with Aldo combined with SB-216763 (a GSK-3beta inhibitor) for 4 weeks. Hemodynamic, cardiac, and renal parameters were assayed at the indicated time. Here we found that rats treated with Aldo presented cardiac and renal hypertrophy and dysfunction. Cardiac and renal expression levels of molecular markers attesting inflammation and fibrosis were increased by Aldo infusion, whereas the treatment of SB-216763 reversed these alterations. SB-216763 suppressed cardiac and renal inflammatory cytokines levels (TNF-a, IL-1beta, and MCP-1). Meanwhile, SB-216763 increased the protein levels of LC3-II in the cardiorenal tissues as well as p62 degradation, indicating that SB-216763 induced autophagy activation in cardiac, and renal tissues. Importantly, inhibition of autophagy by 3-MA attenuated the role of SB-216763 in inhibiting perivascular fibrosis, and tubulointerstitial injury. These data suggest that SB-216763 protected against Aldo-induced cardiac and renal injury by activating autophagy, and might be a therapeutic option for salt-sensitive hypertension and renal fibrosis. PMID- 29600539 TI - Solvent composition dependent signal reduction of molecular ions generated from aromatic compounds in (+) atmospheric pressure photoionization mass spectrometry. AB - RATIONALE: The ionization process is essential for successful mass spectrometric (MS) analysis because of its influence on selectivity and sensitivity. In particular, certain solvents reduce the ionization of the analyte, thereby reducing the overall sensitivity in atmospheric pressure photoionization (APPI). Since the sensitivity varies greatly depending on the solvents, a fundamental understanding of the mechanism is required. METHODS: Standard solutions were analyzed using a (+)-APPI Q Exactive ion trap mass spectrometer (Thermo Scientific). Each solution was infused directly into the APPI source at a flow rate of 100 MUL/min and the APPI source temperature was 300 degrees C. Other operating mass spectrometric parameters were maintained under the same conditions. Quantum mechanical calculations were carried out using the Gaussian 09 suite program. RESULTS: Density functional theory was used to calculate the reaction enthalpies (?H) of the reactions between toluene and other solvents. The experimental and theoretical results showed good agreement. The abundances of analyte ions were well correlated with the calculated ?H values. Therefore, the results strongly support the suggested signal reduction mechanism. In addition, linear correlations between the abundance of toluene and analyte molecular ions were observed, which also supports the suggested mechanism. CONCLUSIONS: A solvent composition dependent signal reduction mechanism was suggested and evaluated for the (+)-APPI-MS analysis of polyaromatic hydrocarbons (PAHs) generating mainly molecular ions. Overall, the evidence provided in this work suggests that reactions between solvent cluster(s) and toluene molecular ions are responsible for the observed reductions in signal.

AB - Testosterone gel formulations have become a popular testosterone replacement therapy in patients with hypogonadism since their advent in the year 2000. The gel formulations restore testosterone levels to mid-normal physiological levels (14-17.5 nmol/L) as early as within 24 h, and help alleviate the signs and symptoms of testosterone deficiency, thereby leading to an improved quality of life. Although testosterone gels have a favourable efficacy and safety profile as compared to injectable and patch formulations, risk of secondary exposure poses a challenge. Approved testosterone topical formulations include Tostrex(r) (Tostran(r) , Fortesta(r) ), Androgel(r) (Testogel(r) ), Testim(r) and Axiron(r) (solution), which have a favourable efficacy profile and positively impacted patient-reported outcome(s). Besides, Testavan, which is a 2% testosterone gel, is under registration in Europe and already approved in Australia in May 2017. Testavan uses a novel hydroalcoholic and highly viscous topical formulation. This product comes with a metered dose dispenser and a cap applicator that allows a hands-free application for precise dispensing and application.

AB - The use of conventional echocardiography in the intensive care unit (ICU) is today established to assess left and right ventricular systolic function, for preload determination and procedural guidance. Next step in ICU echocardiography could be the use of novel ultrasound techniques such as strain echocardiography to assist in the management of patients with acute coronary syndrome, heart failure, or pulmonary embolism. This review has gathered the available evidence supporting the incremental value of strain in the diagnostic workup of cardiac diseases treated in ICU. PMID- 29600545 TI - Strategies to support pressure injury best practices by the inter-professional team: A systematic review. AB - Optimal pressure injury (ulcer) management by the inter-professional team requires appropriate health care system and organisational resources, infrastructure, and policies. A systematic review was conducted on pressure injury care-related education and health care system-/organisation-level strategies. A search for relevant articles published between January 2006 and October 2014 was applied to 8 databases. Ultimately, 22 articles pertaining to education and training and 12 articles pertaining to health care system and organisation supports for pressure injury care were included in the systematic review. A lack of pressure injury assessment and management knowledge by health care professionals was an overriding theme in the education literature. Some of the methods preferred for pressure injury education among nurses and physicians included information technology (eg, e-learning) with technology support and the use of high-quality wound pictures. Although the evidence is scarce, the literature did highlight specific system- and organisation-level barriers and enablers that influence practice change, including inter-professional communication and human resource investments. In conclusion, (1) the current evidence on the education and system-level enablers, barriers, and strategies to optimise pressure injury best practices requires further investigation, and (2) multi-faceted, up-stream, evidence-based approaches for pressure injury care are essential to improve health care and patient-related outcomes.

AB - Diabetes often causes learning and memory deficits, which leads to unfavorable behavioral performance. In this study, we investigated the effects of long non coding RNA (lncRNA) ANRIL on learning, memory abilities, and hippocampal neuronal apoptosis via the NF-kappaB signaling pathway in streptozotocin (STZ)-induced diabetic rats. After successful establishment of diabetic rat models, the subjects were then assigned into the DM, DM + si-ANRIL, DM + si-negative control (si-NC) groups, as well as an additional normal group. Morris water maze test was employed to assess behavioral performance of rats, followed by the recording of body weight and blood glucose levels. Expressions of ANRIL, NF-kappaB signaling pathway-related, and apoptosis-related genes were examined by qRT-PCR and western blotting. Rat hippocampus expression levels of cleaved-caspase-3 were determined by immunofluorescence. Cell apoptosis was examined by TUNEL assay. Versus to the normal group, revealed there to be activation of the NF-kappaB signaling pathway, decreased weight, increased blood glucose, increased escape latency, reduced residence time, memory impairment, increased cleaved-caspase-3 expression, and increased apoptosis were detected in the DM and DM + si-NC groups. The DM + si ANRIL group exhibited inhibited NF-kappaB signaling pathway, weight loss, decreased blood glucose, recovered memory, decreased cleaved-caspase-3 expression and reduced apoptosis compared to the DM group, with higher weight of rats, lower blood glucose levels, and stronger memory abilities in the DM + si-ANRIL group. Taken together, these findings indicate that silencing lncRNA ANRIL promotes memory recovery and decreases hippocampal neurons apoptosis in diabetic rats through the inhibition of the NF-kappaB signaling pathway.

AB - The Wnt signaling pathway is a highly conserved system that regulates complex biological processes across all metazoan species. At the cellular level, secreted Wnt proteins serve to break symmetry and provide cells with positional information that is critical to the patterning of the entire body plan. At the organismal level, Wnt signals are employed to orchestrate fundamental developmental processes, including the specification of the anterior-posterior body axis, induction of the primitive streak and ensuing gastrulation movements, and the generation of cell and tissue diversity. Wnt functions extend into adulthood where they regulate stem cell behavior, tissue homeostasis, and damage repair. Disruption of Wnt signaling activity during embryonic development or in adults results in a spectrum of abnormalities and diseases, including cancer. The molecular mechanisms that underlie the myriad of Wnt-regulated biological effects have been the subject of intense research for over three decades. This review is intended to summarize our current understanding of how Wnt signals are generated and interpreted. This article is categorized under: Biological Mechanisms > Cell Signaling Developmental Biology > Stem Cell Biology and Regeneration. PMID- 29600546 TI - Cooperative Catalysis with Coupled Chiral Induction in 1,3-Dipolar Cycloadditions of Azomethine Ylides. AB - 1,3-Dipolar cycloadditions (1,3-DC) between imino esters (as precursors of N metallated azomethine ylides) and pi-deficient alkenes are promoted by cooperative asymmetric Lewis acid/Bronsted base catalysis. The components of these catalytic pairs are silver salts derived from enantiopure commercially available BINOL-based phosphoric acids and Cinchona alkaloids. Chiral phosphoric silver(I) salts promote HOMO raising of in situ formed 1,3-dipoles, whereas protonated cinchona alkaloids generate a LUMO lowering for the dipolarophiles resulting in a global acceleration of the 1,3-DC. The best results were obtained with BINOL-derived silver phosphate and hydrocinchonine. Matching between both cooperative metallo- and organocatalyst results in an enhanced enantiomeric excess, superior to that reached by both separate components. NOESY experiments and DFT calculations are compatible with a non-covalent interaction (hydrogen bond) between both catalysts, which results in close contacts and mutually coupled chiral environments.

AB - : As a consequence of the genomic revolution, a large number of publications describing paroxysmal movement disorders have been published in the last few years, shedding light on their molecular pathology. Routine gene testing is not necessary to guide treatment for typical forms of paroxysmal kinesigenic dyskinesia (PKD), paroxysmal nonkinesigenic dyskinesia (PNKD), and episodic ataxia type 1 or 2. It can, however, be helpful in the management of atypical or complex cases, especially for genetic counselling, treatment strategies, and the offer of preimplantation genetic diagnosis. Antiepileptic drugs remain the treatment of choice for PKD and episodic ataxia type 1, benzodiazepines are often useful for PNKD, and episodic ataxia type 2 benefits from acetazolamide regardless of the genetic etiology. WHAT THE PAPER ADDS: A growing number of genes have been associated with classic and newly described paroxysmal movement disorders. Paroxysmal movement disorders share common mechanisms and clinical features with other neurological paroxysmal phenomena including epilepsy and migraine. PMID- 29600550 TI - Assessment of multidirectional movements of the common carotid artery in atherothrombotic stroke using dimensional speckle tracking carotid ultrasonography: A prospective, controlled cohort study. AB - AIM: We aimed to explore the relevance of multidirectional movements of the common carotid artery in atherothrombotic stroke. METHODS AND RESULTS: We prospectively enrolled 69 patients with atherothrombotic stroke (stroke group) and 69 age-matched and sex-matched controls (control group) who underwent carotid ultrasonography. Based on the speckle tracking technique, circumferential and radial movements of the common carotid artery were analyzed from transverse and longitudinal B-mode images of the common carotid artery. Peak longitudinal and radial displacements, strain, and strain rate were measured. Mean age of the overall population was 64 +/- 11 years, and 57% (78 patients) were men. In the transverse image, circumferential strain was significantly lower in the stroke group than in the control group (5.6 +/- 1.6 vs 4.2 +/- 1.7, P < .001). In multivariate logistic regression analysis, circumferential strain was independently associated with stroke (odds ratio: 0.60, P = .001). Compared with conventional risk factors, as well as carotid intima-media thickness and carotid plaque, the addition of a strain parameter appeared to improve discrimination of a stroke event (area under the receiver operating characteristic curve: 0.65 and 0.75 vs 0.84, respectively; P < .05 for both). CONCLUSIONS: Circumferential strain of the common carotid artery might serve as a novel surrogate marker of atherothrombotic stroke. Multidirectional strain imaging of the common carotid artery may provide more information than conventional carotid ultrasonography and identify clinical risk factors for risk stratification of an acute stroke event. PMID- 29600551 TI - Hand distance modulates the electrophysiological correlates of target selection during a tactile search task. AB - This study investigated whether the N140cc ERP component, described as a possible electrophysiological marker of target selection in touch, was modulated by body posture. Participants performed a tactile search task in which they had to localize a tactile target, presented to the left or right hand, while a simultaneous distractor was delivered to the opposite hand. Importantly, the distance between target and distractor (hands separation) was manipulated in different experimental conditions (near vs. far hands). Results showed reduced errors and enhanced amplitudes of the late N140cc when the hands were far apart than in close proximity. This suggests that the competition between target and distractor is stronger when the hands are close together in the near condition, resulting in a degraded selection process. These findings confirm that the N140cc reflects target selection during the simultaneous presentation of competing stimuli and demonstrate for the first time that the attentional mechanisms indexed by this ERP component are based at least in part on postural representations of the body.

AB - OBJECTIVE(S): The objective of the study was to explore and describe the health seeking experience of North Korean women defectors settled in South Korea. DESIGN AND SAMPLE: A qualitative study was conducted using Colaizzi's phenomenological method. Participants were 10 North Korean women defectors. MEASURES: Data were collected through in-depth, unstructured interviews with individual participants. RESULTS: A total of 24 themes, eight theme clusters, and four categories emerged. The structure of the health-seeking experience for them was identified as 'having new opportunities to better understand my own body and protecting my own health while adapting to the health care system of the South'. The four categories were: finding out about my own body, confusion regarding the medical treatment, enjoying the health care benefits, and protecting my own health. CONCLUSIONS: The findings of this study will help improve the understanding of the health-seeking experience of North Korean women defectors and provide valuable resources to assist in caring for their health needs. This will contribute to preparing the groundwork to enhance the quality of their remaining life in South Korea. PMID- 29600553 TI - A multiple mediator analysis approach to quantify the effects of the ADH1B and ALDH2 genes on hepatocellular carcinoma risk. AB - Previous work suggested a genetic component affecting the risk of hepatocellular carcinoma (HCC) and mediation analyses have elucidated potential indirect pathways of these genetic effects. Specifically, the effects of alcohol dehydrogenase (ADH1B) and aldehyde dehydrogenase (ALDH2) genes on HCC risk vary based on alcohol consumption habits. However, alcohol consumption may not be the only mediator in the identified pathway: factors related to alcohol consumption may contribute to the same indirect pathway. Thus, we developed a multimediator model to quantify the genetic effects on HCC risk through sequential dichotomous mediators under the counterfactual framework. Our method provided a closed form formula for the mediation effects through different indirect paths, which requires no assumption for the rarity of outcome. In simulation studies of a finite sample, we presented the utility of the method with the variance of the effects estimated using the delta method and bootstrapping. We applied our method to data from participants in Taiwan (580 cases and 3,207 controls) and quantified the mediation effects of single nucleotide polymorphisms (SNPs) in the ADH1B and ALDH2 genes on HCC through alcohol consumption (yes/no) and high alanine transaminase (ALT) levels (greater than or equal to 45 U/L or below 45 U/L). Assuming a dominant risk model, we identified that the SNPs' effects through alcohol consumption is more significant than through ALT levels on HCC risk. This new method provides insight to the magnitude of various casual mechanisms as a closed form solution and can be readily applied in other genomic studies. PMID- 29600554 TI - Preparation and evaluation of open-tubular capillary column combining a metal organic framework and a brush-shaped polymer for liquid chromatography. AB - In this work, an open-tubular capillary liquid-phase column was prepared by modifying chain polymer on the inner surface of capillary and chemical bonding of metal organic frameworks, NH2 -UiO-66, to the brushes of chain polymer (poly(glycidyl methacrylate)). Besides advantages of facial preparation and good permeability, the chain polymer effectively increases the modification amount of NH2 -UiO-66 nanoparticles to increase the phase ratio of open-tubular capillary column and enhance the interactions with analytes. The results of scanning electron microscope energy-dispersive X-ray spectra indicated that NH2 -UiO-66 nanoparticles were successfully bonded to the chain polymer. Because of the hydrophobic interaction and hydrogen bonding interaction between the analytes and the ligand of NH2 -UiO-66, different analytes were well separated on the NH2 -UiO 66-modified poly(glycidyl methacrylate) capillary (1.12 m * 25 MUm id * 365 MUm od) with the high absolute column efficiency reaching 121 477 plates, benefiting from an open-tubular column and low mass transfer resistance provided by polymer brush and metal-organic framework crystal. The relative standard deviations of the retention time for run-to-run, day-to-day, and column-to-column (n = 3) runs are below 4.28%, exhibiting good repeatability. Finally, the column was successfully applied to separation of flavonoids in licorice. PMID- 29600555 TI - Right atrial structure and function in patients with hypertension and with chronic heart failure. AB - BACKGROUND: Prior studies have shown that both heart failure (HF) and atrial fibrillation (AF) are factors that impact left atrial function and structure. However, right atrial (RA) function measured as RA emptying fraction (RAEF) on echocardiography has not been analyzed systematically in a chronic HF population. The aim of this study was to assess RA volume index (RAVI) and RAEF in patients with chronic HF and patients with hypertension (HTN) and to relate these findings to other cardiopulmonary ultrasound parameters and 12-month outcomes. METHODS AND RESULTS: In this prospective observational study, we identified 119 patients with chronic HF (64 patients without a history of AF [HF without AF], 55 with AF [HF with AF]), and 127 patients with HTN but without important cardiac disease who underwent routine outpatient transthoracic echocardiography. We found that RAEF was impaired in patients with HF without AF compared to patients with HTN (35% +/ 2 vs 50% +/-1, P < .001), whereas RAVI did not differ between these two groups. Lower RAEF was associated with larger RAVI and higher estimated RA pressures but not with a higher degree of pulmonary congestion by lung ultrasound. Both lower RAEF and higher RAVI were associated with an increased risk of 12-month HF hospitalizations or all-cause death (age, sex, and AF adjusted HR: 4.07, 95% CI: 1.69-9.79; P = .002, vs 2.74, 95% CI: 1.15-6.54, P = .023). CONCLUSIONS: In an outpatient HF cohort, both lower RAEF and increased RAVI were associated with other markers of impaired cardiac function and 12-month adverse events. PMID- 29600557 TI - Corrigendum. PMID- 29600556 TI - 3D bone models to study the complex physical and cellular interactions between tumor and the bone microenvironment. AB - As the complexity of interactions between tumor and its microenvironment has become more evident, a critical need to engineer in vitro models that veritably recapitulate the 3D microenvironment and relevant cell populations has arisen. This need has caused many groups to move away from the traditional 2D, tissue culture plastic paradigms in favor of 3D models with materials that more closely replicate the in vivo milieu. Creating these 3D models remains a difficult endeavor for hard and soft tissues alike as the selection of materials, fabrication processes, and optimal conditions for supporting multiple cell populations makes model development a nontrivial task. Bone tissue in particular is uniquely difficult to model in part because of the limited availability of materials that can accurately capture bone rigidity and architecture, and also due to the dependence of both bone and tumor cell behavior on mechanical signaling. Additionally, the bone is a complex cellular microenvironment with multiple cell types present, including relatively immature, pluripotent cells in the bone marrow. This prospect will focus on the current 3D models in development to more accurately replicate the bone microenvironment, which will help facilitate improved understanding of bone turnover, tumor-bone interactions, and drug response. These studies have demonstrated the importance of accurately modelling the bone microenvironment in order to fully understand signaling and drug response, and the significant effects that model properties such as architecture, rigidity, and dynamic mechanical factors have on tumor and bone cell response. PMID- 29600558 TI - When elephants fall asleep: A literature review on elephant rest with case studies on elephant falling bouts, and practical solutions for zoo elephants. AB - Little attention has been paid to the resting and sleeping behavior of zoo elephants so far. An important concern is when elephants avoid lying down, due to degenerative joint and foot disease, social structure, or stressful environmental changes. Inability or unwillingness to lie down for resting is an important welfare issue, as it may impair sleep. We emphasize the importance of satisfying rest in elephants by reviewing the literature on resting behavior in elephants (Loxodonta africana and Elephas maximus) as well as the documentation of four cases from European zoos and our own direct observations in a zoo group of four female African elephants during 12 entire days. The common denominator in the case reports is the occurrence of a falling bout out of a standing position subsequently to a cessation of lying rest for different periods of time. Although well-known in horses as "episodic collapse" or "excessive drowsiness," this syndrome has not been described in elephants before. To enable its detection, we recommend nocturnal video monitoring for elephant-keeping institutions. The literature evaluation as well as own observational data suggest an inverse relationship between lying rest and standing rest. Preventative measures consist of enclosure modifications that facilitate lying rest (e.g., sand hills) or standing rest in a leaning position as a substitute. Anecdotal observations suggest that the provision of appropriate horizontal environmental structures may encourage safe, sleep-conducive standing rest. We provide drawings on how to install such structures. Effects of providing such structures should be evaluated in the future. PMID- 29600559 TI - Altering Neurospora crassa MOB2A exposes its functions in development and affects its interaction with the NDR kinase COT1. AB - The Neurospora crassa Mps One Binder (MOB) proteins MOB2A and MOB2B physically interact with the Nuclear Dbf2 Related (NDR) kinase COT1 and have been shown to have overlapping functions in various aspects of asexual development. Here, we identified two N. crassa MOB2A residues, Tyr117 and Tyr119, which are potentially phosphorylated. Using phosphomimetic mob-2a mutants we have been able to establish that apart from their previously described roles, MOB2A/B are involved in additional developmental processes. Enhanced conidial germination, accompanied by conidial agglutination, in the phosphomimetic mutants indicated that MOB2A is a negative regulator of germination. Thick-section imaging of perithecia revealed slow maturation and a lack of asci alignment in the mutant strains demonstrating a role for MOB2A in sexual development. We demonstrate that even though MOB2A and MOB2B have some overlapping functions, MOB2B cannot compensate for the roles MOB2A has in conidiation and germination. Altering Tyr residues 117 and 119 impaired the physical interactions between MOB2A and COT1, most likely contributing to some of the observed effects. As cot-1 and the phosphomimetic mutants share an extragenic suppressor (gul-1), we concluded that at least some of the effects imposed by altering Tyr117 and Tyr119 are mediated by the NDR kinase. PMID- 29600560 TI - Contact sensitivity in patients with venous leg ulcer: A multi-centric Indian study. AB - Venous leg ulcers are the most common form of non-healing leg ulcers. They are subjected to treatments such as topical medications, dressings, and compression therapies. This can lead to exposure to a number of allergens with subsequent sensitisation and contact dermatitis of the regional skin. This may contribute to the poor ulcer healing. To detect the various contact sensitisers in patients with venous leg ulcers through patch testing, patients from 6 centres across India with venous leg ulcers of longer than 6 weeks duration were enrolled for the study. They were patch tested using a special parch test kit with 27 antigens. A total of 172 patients were included in the study; 82 (48.2%) tested positive for at least 1 antigen. Among them, polyvalent sensitisation was noted in 71% of patients. Wood tar mix (10.4%) and the framycetin (8.7%) were the most common allergens. There is a high frequency of allergic sensitisation to various ingredients of topical therapies used in the venous ulcer management, which may interfere with wound healing. Avoiding them can help obtain a better therapeutic outcome. PMID- 29600561 TI - Relationships between vital rates and ecological traits in an avian community. AB - Comparative studies about the relationships between vital rates and ecological traits at the community level are conspicuously lacking for most taxa because estimating vital rates requires detailed demographic data. Identifying relationships between vital rates and ecological traits could help to better understand ecological and evolutionary demographic mechanisms that lead to interspecific differences in vital rates. We use novel dynamic N-mixture models for counts to achieve this for a whole avian community comprising 53 passerine species, while simultaneously accounting for density dependence and environmental stochasticity in recruitment and survival and, importantly, correcting our inferences for imperfect detection. Demographic stochasticity is taken into account in the form of the binomial and Poisson distributions describing survival events and number of recruits. We then explore relationships between estimated demographic parameters (i.e., vital rates) and ecological traits related to migration patterns, diet, habitat and nesting location of each species. The relative importance of recruitment and adult survival as contributors to population growth varied greatly among species, and interspecific differences in vital rates partly reflected differences in ecological traits. Migratory mode was associated with interspecific differences in population growth and density dependence. Resident species had higher population growth rates than long- and short-distance migrants. We found no relationships between diet and population growth rate. Habitat differences were associated with different growth rates: alpine, wetland and farmland species had lower population growth rates than forest species. Differences in population growth rates among nesting locations showed that breeding habitat is essential for population dynamics. Our study reveals relationships between ecological traits and contributions of vital rates to population growth and suggests ways in which patterns of population growth fluctuations in a community might be determined by life history.

AB - Patients with systemic sclerosis (SSc) are at a high risk of the development of ischaemic digital ulcers (DUs) that can be complicated with infections, gangrene, and osteomyelitis. The aim of this study is to evaluate the role of endostatin in scleroderma DUs.In total, 90 SSc patients were enrolled in this study. Serum endostatin levels and DU assessment were determined in all SSc patients. The serum levels of endostatin significantly increased with progression of capillaroscopic damage (P < .01). The serum levels of endostatin are significantly (P < .05) higher in SSc patients with new DUs than in SSc patients without new DUs (127 +/- 31.1 ng/mL vs 116.3 +/- 39.7 ng/mL). The Receiver Operating Characteristic (ROC) curves demonstrated good accuracy of new DU prediction for the serum level of endostatin (0.70, P < .01 [95% confidence interval (CI) 0.59-0.81]). Using a cut-off value of 116 ng/mL, the odds ratio was 2.609 (CI 1.075-6.330, P < .05). The serum levels of endostatin are significantly (P < .01) higher in SSc patients with infected DUs than in SSc patients without infected DUs (139.2 [114.6-340.91] ng/mL vs 117.5 [64.3-163.9] ng/mL). Serum levels of endostatin are higher in patients with DUs, especially in those with infected DUs. PMID- 29600563 TI - Alendronate induces osteoclast precursor apoptosis via peroxisomal dysfunction mediated ER stress. AB - Nitrogen-containing bisphosphonates including alendronate (ALN) are the current first line antiresorptive drug in treating osteoporosis. In our study, we found that ALN administration impaired the secretion of platelet derived growth factor BB (PDGF-BB), the most important angiogenic cytokines produced by preosteoclast (POC), in both sham and ovariectomized (OVX) mice. To further understand this phenomenon, we induced bone marrow macrophages (BMMs) to POCs in vitro and detected the effects of ALN particularly in POCs. The proapoptotic effect of ALN in POCs was confirmed by flow cytometry. On the molecular level, we found that farnesyl diphosphate synthase (FDPS) inhibition of ALN led to peroxisomal dysfunction and up regulation of cytoprotective protein glucose-regulated protein (GRP) 78. Peroxisomal dysfunction further induced endoplasmic reticulum (ER) stress in POCs and finally resulted in cell apoptosis marked by reduced expression of B-cell lymphoma 2 (Bcl-2) and increased expressions of CCAAT/enhancer binding protein homologous protein (CHOP), Bcl2 associated X (Bax), and cleaved caspase-3. We concluded that ALN has no selectivity in inhibiting POC and mature osteoclast. For POCs, ALN inhibition of FDPS leads to peroxisomal dysfunction, which further mediates ER stress and finally causes cell apoptosis. Considering that decreased angiogenesis is also an important issue in treating osteoporosis, how to preserve pro-angiogenic POCs while depleting mature osteoclasts is a problem worthy to be solved. PMID- 29600564 TI - Statistical analysis of factors affecting re-operative times in paediatric patients with scar deformity after deep second-degree burn injury. AB - Deep second-degree burn injuries pose a challenge for treating scar deformity in developing paediatric patients. Some patients underwent several re-operations during their development. There was no literature reporting which factors affect re-operative times. In this article, we intend to analyse possible influential factors that are responsible for re-operative times in paediatric patients with scar deformity after deep second-degree burn injuries. From 2010 to 2016, 177 paediatric cases with a history of deep second-degree burn injury who underwent re-operation once, twice, and equal to or more than thrice were recruited to this study, with age ranging from 0 to 18 years. The following factors were analysed: age, gender, size of scar, method for reconstruction, location, postoperative anti-scar treatment, preschool group, school group, combined deformity, and combined method for reconstruction. One-way ANOVA and multi-way ANOVA analysis were used as statistical tools to analyse the above factors and re-operative times. There were 83 male cases and 94 female cases, with an average age of 7.47 years. Statistical significance was achieved for the size of scar (P = 0.000), operation method (P = 0.001), and combined deformity (P = 0.026) under 1-way ANOVA in different re-operative times. The operation methods for the head and neck area (P < 0.05) and the lower extremities (P < 0.05) are critical factors for multi-factor variance analysis in different re-operative times. Multivariate logistic regression analysis also demonstrated that the size of scar was an independent risk factor for the number of operations. Combined operative method was a protective risk factor for the number of operations. There was no statistical significance obtained for other factors. Size of scar, operation method, and combined operation method are the risk factors for re-operative times, while operation methods for the head and neck area and lower extremities are the critical factors for re-operative times. We can use the combined method to resolve scar-related problems in order to reduce re-operative times. PMID- 29600565 TI - Recent research on stimulated emission depletion microscopy for reducing photobleaching. AB - Stimulated emission depletion (STED) microscopy is a useful tool in investigation for super-resolution realm. By silencing the peripheral fluorophores of the excited spot, leaving only the very centre zone vigorous for fluorescence, the effective point spread function (PSF) could be immensely squeezed and subcellular structures, such as organelles, become discernable. Nevertheless, because of the low cross-section of stimulated emission and the short fluorescence lifetime, the depletion power density has to be extremely higher than the excitation power density and molecules are exposed in high risk of photobleaching. The existence of photobleaching greatly limits the research of STED in achieving higher resolution and more delicate imaging quality, as well as long-term and dynamic observation. Since the first experimental implementation of STED microscopy, researchers have lift out variety of methods and techniques to alleviate the problem. This paper would present some researches via conventional methods which have been explored and utilised relatively thoroughly, such as fast scanning, time-gating, two-photon excitation (TPE), triplet relaxation (T-Rex) and background suppression. Alternatively, several up-to-date techniques, especially adaptive illumination, would also be unveiled for discussion in this paper. The contrast and discussion of these modalities would play an important role in ameliorating the research of STED microscopy. PMID- 29600566 TI - Endothelial committed oral stem cells as modelling in the relationship between periodontal and cardiovascular disease. AB - In the present study we have mimicked, in vitro, an inflammatory process using Lipopolysaccharide derived from Porphyromonas Gingivalis (LPS-G) and human Periodontal Ligament Stem Cells induced to endothelial differentiation (e hPDLSCs). The research project has been organized into the three following steps: i) induction of hPDLSCs toward endothelial differentiation; ii) evaluation of the molecular signaling pathway involved in the response to the LPS-G, and iii) functional response evaluation of the living construct constituted by porcine decellularized valve/e-hPDLSCs treated with LPS-G. Obtained results showed that 5 MUg/ml LPS-G stimulus provokes: a slowdown of cell growth starting from 24 hr and the release of IL6, IL8, and MCP1 molecules. Signaling network analyzed showed the activation of TLR4/ NFkB/ERK1/2/p-ERK1/2 signaling mediated by MyD88 in LPS-G stimulated e-hPDLSCs, moreover a time course put in evidence a nuclear traslocation of ERK1/2 and p-ERK1/2 in differentiated samples. Following, the ability of e-hPDLSCs to expand and colonize the decellularized porcine heart valves was appraised at ultrastructural level. Considering that, the Reactive Oxygen Species (ROS) play an important role in the progression and development of cardiovascular disease (CVD), in LPS-G living construct model e hPDLSCs/decellularized porcine heart valves (dPHV), ROS production was assessed. Time lapse experiments evidenced that LPS-G provokes in e-hPDLSCs a rapid and sustained increase in ROS generation, negligible on undifferentiated cells. From obtained data, by multiparametric analyses, a reasonable conclusion may be that the inflammation process activated by LPS-G can affect endothelial cells and could represent in vivo a possible pathological and predictor state of CVD.

AB - Nuclear magnetic resonance (NMR) provides in situ information about selected isotope densities in samples and objects, while also providing contrast through rotational and translational molecular dynamics. These parameters are probed not only in NMR spectroscopy and imaging but also in nondestructive materials testing by mobile stray-field NMR, the unique properties of which are valuable in cultural heritage studies. We present recent progress in the analysis of cultural heritage with mobile 1 H NMR stray-field sensors, for which the detection zone is outside of the NMR magnet. Prominent applications include the analysis of stratigraphies in paintings and frescoes, and the assessment of material states changing under the impact of aging, conservation, and restoration.

For the child, obesity often involves major social challenges. Within the framework of social studies of children and childhood and employing the concept of biopedagogies, I explore how children with severe obesity who participate in a long-term rehabilitation programme changed the perception of their bodies from 'being fat' to 'suffering from obesity' by embracing the biopedagogies involved. Due to this transformation, 'obesity' was made into an entity - 'a thing' that the children could work on -, which was used for coping and change. The article is based on an ethnographic field study of a Norwegian randomized medical intervention trial for children with obesity.

Recently, we identified a putative gene cluster for the biosynthesis of actinonin. Here, we confirm and characterize this cluster by heterologous pathway expression and gene-deletion experiments. We assigned the biosynthetic gene cluster to actinonin production and determine the cluster boundaries. Furthermore, we establish that ActI, an AurF-like oxygenase, is responsible for the N-hydroxylation reaction that forms the hydroxamate warhead. Our findings provide the basis for more detailed investigations of actinonin biosynthesis. PMID- 29600570 TI - Medical communication: the views of simulated patients. AB - CONTEXT: Simulated patients (SPs) are extensively used in the teaching of medical communication, both for students and doctors. They occupy a unique middle ground between patients and physicians: although free from the prejudices that medical training brings, they work closely with clinical tutors to promote the principles of patient-centred consulting. Despite this, there is relatively little research around their views on what makes for good communication practice. This study aims to address this gap in the literature through a qualitative analysis of SPs' opinions, especially in the context of medical student communication. METHODS: Eighteen SPs from two medical schools, Hull York Medical School and Durham, were interviewed, using an in-depth, one-to-one, semi-structured approach. Data, transcribed verbatim, were thematically analysed. RESULTS: Three global themes were identified: (i) listening and empathy and showing it, (ii) continual human connection and (iii) information flow from the patient. These three themes, termed the communication triad, form a type of virtuous circle, each facilitating the other. Listening and empathy were facilitated through attributes, including attentive non-verbal communication, and through responding to cues, including making effective empathetic statements. Continual human connection was facilitated through successful beginnings, including preferring open questions to 'robotic' tick-list questions and allowing patients time to have their say. Mirroring, professional appearance, appropriate physical contact and a human approach were amongst other factors facilitating connection with patients. Information flow was encouraged by factors including showing an interest in the patient and use of silence; flow was curtailed by undesirable attributes, including interrupting, dismissive communication and making assumptions about aspects such as sexuality. CONCLUSION: This first in-depth study of SPs' views on medical consulting identifies a communication triad that both affirms and builds on the current literature base. Five novel teaching points emerge, with clear relevance for best practice communication teaching and curricula design. PMID- 29600571 TI - Acute aortic regurgitation following fibrous strand rupture of aortic valve successfully diagnosed by transesophageal echocardiography. AB - Fibrous strand rupture is a rare cause of acute aortic regurgitation, but is a serious condition because of acute massive regurgitation. Therefore, prompt and accurate diagnosis is required. We saw a 53-year-old man who presented with acute dyspnea without evidence of infection. Transesophageal echocardiography revealed severe aortic regurgitation because of fibrous strand rupture. We performed surgery and found that the fibrous strand of the right coronary leaflet was ruptured. In cases of acute aortic regurgitation, the rupture of fibrous strand should be considered and transesophageal echocardiography would be very useful to diagnose it. PMID- 29600572 TI - Adenine alleviates iron overload by cAMP/PKA mediated hepatic hepcidin in mice. AB - Hemochromatosis is prevalent and often associated with high rates of morbidity and mortality worldwide. The safe alternative iron-reducing approaches are urgently needed in order to better control iron overload. Our unbiased vitamin screen for modulators of hepcidin, a master iron regulatory hormone, identifies adenine (vitamin B4) as a potent hepcidin agonist. Adenine significantly induced hepcidin mRNA level and promoter activity activation in human cell lines, possibly through BMP/SMAD pathway. Further studies in mice validated the effect of adenine on hepcidin upregulation. Consistently, adenine dietary supplement in mice led to an increase of hepatic hepcidin expression compared with normal diet fed mice via BMP/SMAD pathway. Notably, adenine-rich diet significantly ameliorated iron overload accompanied by the enhanced hepcidin expression in both high iron-fed mice and in Hfe-/- mice, a murine model of hereditary hemochromatosis. To further validate this finding, we selected pharmacological inhibitors against BMP (LDN193189). We found LDN193189 strongly blocked the hepcidin induction by adenine. Moreover, we uncovered an essential role of cAMP/PKA-dependent axis in triggering adenine-induced hepcidin expression in primary hepatocytes by using 8 br cAMP, a cAMP analog, and H89, a potent inhibitor for PKA signaling. These findings suggest a potential therapeutic role of adenine for hereditary hemochromatosis. PMID- 29600573 TI - The association between Helicobacter pylori infection and the risk of advanced colorectal neoplasia may differ according to age and cigarette smoking. AB - BACKGROUND: The association between Helicobacter pylori infection and advanced colorectal neoplasia (ACN) remains controversial. This study aimed to clarify the association between H. pylori infection and ACN according to age groups. METHODS: We retrospectively analyzed the association between H. pylori infection and ACN in patients aged <50 and >=50 years receiving a health checkup that included colonoscopy. Helicobacter pylori positivity was determined by the results of serum anti-H. pylori immunoglobulin G or rapid urease test, if the anti-H. pylori immunoglobulin G was in the borderline range. RESULTS: Among the 19 337 patients who were included, 56.2% and 3.4% were positive for H. pylori and ACN, respectively. Helicobacter pylori infection independently increased the risk of ACN in patients aged <50 years (odds ratio [OR], 1.602; 95% confidence intervals [CI], 1.194-2.150) but not in patients aged >=50 years (OR, 1.046; 95% CI, 0.863 1.268). The positive association between H. pylori infection and ACN was affected by smoking history. When stratified by age and smoking history, H. pylori infection conferred an increased risk of ACN in patients aged <50 years with a history of smoking (OR, 1.926; 95% CI, 1.336-2.775) but not in the other 3 groups (3-way interaction test P = .023). Among patients aged <50 years with ACN, ACN in the left colon was found more frequently in patients with H. pylori infection and a history of smoking than in those without (69.3% vs 54.4%, respectively; P = .031). CONCLUSIONS: Helicobacter pylori infection confers an increased risk of ACN, but the association may differ according to age and smoking history. PMID- 29600574 TI - Quantitative assessment of mAb Fc glycosylation of CQA importance by capillary electrophoresis. AB - The attached carbohydrates at the highly conserved asparagine-linked glycosylation site in the CH 2 domain of the fragment crystallizable (Fc) region of monoclonal antibody therapeutics can play an essential role in their mechanism of action, including ADCC, CDC, anti-inflammatory functions, and serum half-life. Thus, this particular glycosylation represents one of the important critical quality attributes (CQA) of therapeutic monoclonal antibodies, which should be closely monitored and controlled during all stages of biopharmaceutical manufacturing. To study Fc glycosylation related quantitative critical quality attributes, the N-glycan pool of adalimumab (Humira(r) ) was spiked with increasing amounts of mannose-5 oligosaccharide, a glycan with high CQA importance. The method enabled precise quantitative CQA assessment with high detection sensitivity. PMID- 29600575 TI - Matrix metalloproteinase-9 expression of GCTSC in peripheral tissue and central tissue of GCTB. AB - Giant cell tumor stromal cell (GCTSC) is the tumor cell of giant cell tumor of bone (GCTB). The biomarkers characterization of GCTSC is critical for the selection of GCTB targeting drugs. We believe the main functions of GCTSC in different part of tumor should be different for different environment. Then the biological behavior and molecular biomarkers of GCTSC should be different as well. Based on this idea, we focused on GCTSC which located in central tissue, peripheral tissue and took MMP-9 as the breakthrough point to carry out research. The results showed MMP-9 staining grade of GCTSC which located in central tissue was slight, whereas multinucleated giant cell staining grade was high. The peripheral tissue was consisted by almost GCTSC with high MMP-9 staining degree and mRNA expression. This study also provided clues and inspiration for reducing GCTB recurrence rate after intralesional curettage with MMP-9 targeted therapy which were aimed at the residual peripheral tissue. PMID- 29600576 TI - Meta-analysis of trials comparing cefazolin to antistaphylococcal penicillins in the treatment of methicillin-sensitive Staphylococcus aureus bacteraemia. AB - AIMS: The objective of this study was to determine the effectiveness and safety of cefazolin vs. antistaphylococcal penicillin (ASP) in the treatment of methicillin-sensitive Staphylococcus aureus (MSSA) bacteraemia. METHODS: The databases of PubMed, Embase and Cochrane Central were used to identify comparative trials of cefazolin vs. ASP in MSSA bacteraemia. Meta-analysis of included trials was performed to assess any differences regarding mortality, clinical cure, recurrence and withdrawal from adverse effects between groups. Data were analysed using fixed effect model. Studies were weighted using Mantel Haenszel methodology. Heterogeneity was calculated using the I2 statistic. RESULTS: Nine retrospective and one prospective trials were identified involving 4728 patients, 2954 with ASP and 1774 with cefazolin. Meta-analysis showed a lower mortality rate with cefazolin vs. ASP using fixed effect model [risk ratio (RR) 0.78, 95% confidence interval (CI) 0.69-0.88, P < 0.0001] with borderline high heterogeneity (I2 = 51%). Clinical cure was noted more often with cefazolin (RR 1.09, 95% CI 1.02-1.17, P = 0.02), although no difference was noted with relapse (RR 1.29, 95% CI 0.96-1.74 P = 0.09). Analysis also showed more withdrawals from adverse events with ASP vs. cefazolin (RR 0.27, 95% CI 0.16 0.47, P < 0.00001). A minority of patients enrolled in these trials were admitted to the intensive care unit or had endocarditis (11.4% with ASP and 9% with cefazolin). CONCLUSION: Our meta-analysis of retrospective data demonstrate that cefazolin is more effective and safer ASP in patients with MSSA bacteraemia from various causes. Low quality of trials, borderline high heterogeneity, and possible publication bias may limit the validity of our findings. Randomized trials are needed to confirm these findings. PMID- 29600577 TI - Assessment of passive musculoarticular ankle stiffness in children, adolescents and young adults with haemophilic ankle arthropathy. AB - OBJECTIVES: To measure passive musculoarticular ankle stiffness (PMAAS) and its intra- and interday reliability in adult control subjects without ankle disorders. We also sought to quantify PMAAS in children, adolescents and young adults with haemophilia (CAAwH) taking into account the accurate tibiotalar and subtalar joints structural status obtained by magnetic resonance imaging (MRI). METHODS: We included 23 CAAwH and 23 typically developing boys (TDB) matched by age, weight and height, along with 25 healthy volunteers for reliability assessment. All CAAwH underwent bilateral ankle MRI, with anatomical status assessed using the International Prophylaxis Study Group MRI scale. All CAAwH underwent PMAAS testing for both sides randomly vs the dominant side (DS) in TDBs. For assessing viscous stiffness (VS) and elastic stiffness (ES), eight different oscillation frequencies were randomly repeated three times for each subject. RESULTS: Good-to-excellent intra- and interday reliability was observed for ES and VS variables. No relevant differences were observed between the ankle viscoelastic properties in CAAwH without joint damage and matched TDBs, whereas the study revealed significantly increased ES in the affected ankles of CAAwH with severe unilateral joint involvement compared to the non-affected joint. CONCLUSION: This study confirmed increased ES in the severely affected ankles of CAAwH compared to non-affected sides. No differences in the ankle viscoelastic properties of CAAwH with or without joint damage were observed, however, compared to matched TDB. PMID- 29600578 TI - Successful treatment of enteroatmospheric fistulas in combination with negative pressure wound therapy: Experience on 3 cases and literature review. AB - Enteroatmospheric fistulas (EAF) are rare but challenging and morbid complications of abdominal surgery and require time- as well as resource consuming management. Furthermore, they severely affect patients' quality of life. Several treatment modalities for EAF management are described in the literature. We describe 3 consecutive cases of EAF treatment by employing negative pressure wound therapy (NPWT) along with either a special silicone fistula adapter or a Silo-Vac-like system in another case to isolate the fistula from the remaining abdominal wound. Spontaneous fistula closure was achieved in 2 of the 3 cases, and surgical resection of the small bowel segment harbouring EAF opening was possible in a third case after wound conditioning. The rate of fistula closure was 100% (n = 3/3). Compartmentalisation of the contaminated area using NPWT accelerated healing of the open abdominal wound remarkably. In summary, we present a useful tool for the challenging management of EAF and review the literature on different treatment options of EAF available today. PMID- 29600579 TI - Synthesis and Bioactivity of Polymer-Based Synthetic Mimics of Antimicrobial Peptides (SMAMPs) Made from Asymmetrically Disubstituted Itaconates. AB - A series of asymmetrically disubstituted diitaconate monomers is presented. Starting from itaconic anhydride, functional groups could be placed selectively at the two nonequivalent carbonyl groups. By using 2D NMR spectroscopy, it was shown that the first functionalization step occurred at the carbonyl group in the beta position to the double bond. These monomers were copolymerized with N,N dimethylacrylamide (DMAA) to yield polymer-based synthetic mimics of antimicrobial peptides (SMAMPs). They were obtained by free radical polymerization, a metal-free process, and still maintained facial amphiphilicity at the repeat unit level. This eliminates the need for laborious metal removal and is advantageous from a regulatory and product safety perspective. The poly(diitaconate-co-DMAA) copolymers obtained were statistical to alternating, and the monomer feed ratio roughly matched that of the repeat unit content of the copolymers. Investigations of varied R group hydrophobicity, repeat unit ratio, and molecular mass on antimicrobial activity against Escherichia coli and on compatibility with human keratinocytes showed that the polymers with the longest R groups and lowest DMAA content were the most antimicrobial and hemolytic. This is in agreement with the biological activity of previously reported SMAMPs. Thus, the design concept of facial amphiphilicity has successfully been transferred, but the selectivity of these polymers for bacteria over mammalian cells still needs to be optimized.

PMID- 29600580 TI - Curcumin nanoparticles potentiate therapeutic effectiveness of acitrein in moderate-to-severe psoriasis patients and control serum cholesterol levels. AB - OBJECTIVES: In this study, nanoparticles of curcumin were developed and orally administered to moderate-to-severe psoriasis (Psoriasis Area Severity Index values, PASI > 10) patients, in a placebo controlled, double blind, randomised clinical trial to evaluate the effectiveness. METHODS: Diverse binary systems of curcumin and hydrophilic polymers were investigated to optimise solubility and stability in terms of curcumin residual content and size of the crystals. Nanocrystals of curcumin stabilised with PVP (1 : 0.5, w/w), were characterised using X-ray diffraction, differential scanning calorimetry, TEM analyses and stability studies. The formulation was evaluated with a parallel artificial membrane permeability assay to predict the passive intestinal absorption. The first group of patients was treated orally with acitretin (0.4 mg/kg per day) plus nanocurcumin (3 g/day), the second group with acitretin, for 12 weeks. KEY FINDINGS: Curcumin nanoparticles were homogeneous and stable systems. Curcumin permeability was significantly enhanced when compared with aqueous saturated solution of curcumin. The reduction in PASI was significantly higher in patients treated with curcumin (P < 0.0001) and cholesterol serum levels remained unchanged in patients treated with acitretin plus nanocurcumin. CONCLUSIONS: Curcumin nanoparticles represent an effective adjuvant therapy in moderate-to severe psoriasis patients treated with oral acitretin, improving their lipid serum profile. PMID- 29600582 TI - Promoting interdisciplinary shared mental models. AB - BACKGROUND: Emergency Medicine (EM) and Hospital Medicine (HM) providers frequently interact when transitioning patients from the emergency department (ED) to the inpatient unit; however, there is infrequent collaboration between these subspecialties, and effective communication in EM-HM provider handover is an area for improvement. Shared mental models can enhance communication and safety. The purpose of this article is to describe the implementation of an interdisciplinary conference to allow providers to create shared mental models, and to assess the impact on attitudes and behaviours towards communication and collaboration outside the competing attentions of patient care environments. METHODS: The authors instituted a quarterly interactive case-based conference at an academic tertiary care children's hospital in which EM and HM subspecialty trainees co-facilitate evidence-based interactive presentations of clinical, diagnostic or management dilemmas. The conferences were evaluated via repeated cross-sectional surveys of EM and HM providers, as well as session evaluations. Surveys included multiple-choice, Likert-scale and free-text responses to assess the degree of interaction and collaboration between the divisions and provider attitudes toward changes in clinical practice. RESULTS: Assessment of the EM-HM collaborative conferences demonstrated trends towards increased interaction between divisions and increased discussion about management decisions among colleagues. Two-thirds of individuals who attended at least one conference felt that having attended an interdisciplinary conference influenced future management decisions. Effective communication in EM-HM provider handover is an area for improvement CONCLUSIONS: Interdisciplinary conferences provide a forum for cross specialty communication to discuss management differences in a low-stress educational environment, and allow providers to develop shared mental models for effective, safe patient care. PMID- 29600583 TI - Compositional Analysis of Coronary Artery Calcification in Dialysis Patients in vivo by Dual-Energy Computed Tomography Angiography. AB - While vascular calcification is an important factor regulating prognosis in dialysis patients, its components have not been adequately studied. We analyzed in vivo components of calcification in the coronary arteries of dialysis patients using the effective atomic number from dual-energy computed tomography. In dialysis patients (hemodialysis, N = 10; peritoneal dialysis, N = 12), average of median effective atomic number was 13.8 in the hemodialysis group, and 13.7 in the peritoneal dialysis group. No significant differences were seen between groups, with calcium oxalate monohydrate identified as the most common component in each. To confirm the accuracy of this method, we investigated the composition of surgically removed calcified tissues using already established methods. Comparison with the effective atomic number from dual-energy computed tomography showed that the results of calcification analysis were the same. We concluded that calcium oxalate monohydrate might be one of the major components of coronary artery calcification in dialysis patients. PMID- 29600584 TI - Plasma glutathione suggests oxidative stress is equally present in early- and late-onset bipolar disorder. AB - OBJECTIVES: We previously demonstrated oxidative stress in bipolar patients and a relationship between the age of illness onset and total glutathione, a principal antioxidant. In this study, we sought to replicate these findings in a new cohort of patients. METHODS: We recruited bipolar patients from Warneford Hospital, Oxford, UK, of similar age and grouped them according to age of onset of illness. The early-onset group comprised patients with onset at <23 years, and the late group comprised patients with onset at >30 years. A third group, comprising age matched healthy volunteers, was also included. Reduced and oxidized glutathione, cysteine, and cystine were determined in plasma, using high-performance liquid chromatography. Mitochondrial DNA copy number, measured in whole blood, was also compared between patients and healthy controls. RESULTS: Significant increases in oxidative stress were observed in the patient groups, compared with the control group; however, no differences in glutathione-related oxidative stress measures were detected between the early- and late-onset bipolar patient groups. No differences were observed in the amount of mitochondrial DNA, and there was no correlation with mood state. CONCLUSION: Using a more accurate method to quantify oxidative stress than in our previous study, we show that oxidative stress is a consistent feature of bipolar disorder. Although we did not reproduce our finding correlating age of onset of illness to oxidative stress, we have shown, once again, that oxidative stress is a consistent feature of bipolar disorder.

PMID- 29600587 TI - TMEM16A inhibition impedes capacitation and acquisition of hyperactivated motility in guinea pig sperm. AB - Ca2+ -activated Cl- channels (CaCCs) are anionic channels that regulate many important physiological functions associated with chloride and calcium flux in some somatic cells. The molecular identity of CaCCs was revealed to be TMEM16A and TMEM16B (also known as Anoctamin or ANO1 and ANO2, respectively) in all eukaryotes. A recent study suggests the presence of TMEM16A in human sperm and a relationship with the rhZP-induced acrosome reaction. However, to the best of our knowledge, little is known about the role of TMEM16A in other spermatic processes such as capacitation or motility. In this study, we evaluated the effects of two TMEM16A antagonists on capacitation, acrosome reaction, and motility in guinea pig sperm; these antagonists were T16Ainh-A01, belonging to a second generation of potent antagonists of TMEM16A, and niflumic acid (NFA), a well-known antagonist of TMEM16A (CaCCs). First of all, we confirmed that the absence of Cl- in the capacitation medium changes motility parameters, capacitation, and the progesterone-induced acrosome reaction. Using a specific antibody, TMEM16A was found as a protein band of ~120 kDa, which localization was in the apical crest of the acrosome and the middle piece of the flagellum. Inhibition of TMEM16A by T16Ainh-A01 affected sperm physiology by reducing capacitation, blocking the progesterone-induced acrosome reaction under optimal capacitation conditions, inhibiting progressive motility, and the acquisition of hyperactivated motility, diminishing [Ca2+ ]i, and increasing [Cl- ]i. These changes in sperm kinematic parameters provide new evidence of the important role played by TMEM16A in the production of sperm capable of fertilizing oocytes. PMID- 29600588 TI - Cost-utility of a six-month programmed sports therapy (PST) in patients with haemophilia. AB - INTRODUCTION: Recurrent musculoskeletal haemorrhages in people with haemophilia (PwH) lead to restrictions in the locomotor system and, as a result, in physical performance, too. Due to its physical and psychological benefits, sport is increasingly re-commended for haemophilic patients. Evidence on the cost effectiveness of sports therapy is still lacking. AIM: The aim of this study was to determine the cost-effectiveness of a 6-month programmed sports therapy (PST). METHODS: The cost-effectiveness of the 6-month PST was assessed from a societal perspective alongside a RCT using cost-utility analysis. The analysis included 50 PwH with moderate-to-severe haemophilia A and B and a training period over 6 months. The health-related quality of life was measured with the EuroQoL-domain questionnaire. Resource utilization was assessed by questionnaire before and after the intervention. A cost-effectiveness acceptability curve was constructed, and sensitivity analyses were performed. RESULTS: During the 6-month study period, mean adjusted total healthcare costs were lower (mean difference: -22 805 EUR; 95%-CI: -73 944-48 463; P = .59) and the number of QALYs was higher in the intervention group (mean difference: 0.3733; 95%-CI: 0.0014-0.0573; P = .04). The probability of an incremental cost-effectiveness ratio <50 000 EUR per QALY was 71%. The performed sensitivity analysis confirmed these results. CONCLUSION: Results showed that the PST is effective in terms of a significant gain of QALYs. Furthermore, results weakly indicate the potential of the PST to reduce healthcare costs. Future studies should expand the observation period to have a closer look at the influence of PST on lifetime costs. PMID- 29600589 TI - Associations of Peritoneal Glucose Load With Male Sexual Dysfunction and Depression in Peritoneal Dialysis Patients. AB - This cross-sectional study examined possible associations of peritoneal glucose load with male sexual dysfunction and depression in peritoneal dialysis patients. Compared to patients with peritoneal glucose load <=3 g/kg per day, those with load >3 g/kg per day had higher Beck Depression Inventory scores, (18.9 +/- 5.4 vs. 11.4 +/- 5.8, P = 0.002) and lower International Index of Erectile Function scores, serum total testosterone and DHEA [(15.4 +/- 6.4 vs. 45.1 +/- 20.7, P < 0.001), (8.5 +/- 3.0 vs. 13.9 +/- 3.2, P < 0.001), (113.9 +/- 58.8 vs. 280.2 +/- 128.3, P < 0.001); respectively)]. Of participants with peritoneal glucose load >3 g/kg per day, 84.6% had mild to moderate erectile dysfunction and 92.3% had abnormal Beck Depression Inventory scores. Peritoneal glucose load inversely correlated with International Index of Erectile Function scores (P < 0.001), total serum testosterone (P = 0.002) and serum DHEA (P = 0.001); and directly with Beck Depression Inventory scores (P < 0.001) and serum estradiol (P < 0.001). This study demonstrated higher prevalence of sexual dysfunction, depression and sex hormone disturbances in male peritoneal dialysis patients receiving higher peritoneal glucose load. PMID- 29600590 TI - Molecular interactions of thymol with bovine serum albumin: Spectroscopic and molecular docking studies. AB - Thymol is the main monoterpene phenol present in the essential oils which is used in the food industry as flavoring and preservative agent. In this study, the interaction of thymol with the concentration range of 1 to 6 MUM and bovine serum albumin (BSA) at fixed concentration of 1 MUM was investigated by fluorescence, UV-vis, and molecular docking methods under physiological-like condition. Fluorescence experiments were performed at 5 different temperatures, and the results showed that the fluorescence quenching of BSA by thymol was because of a static quenching mechanism. The obtained binding parameters, K, were in the order of 104 M-1 , and the binding number, n, was approximately equal to unity indicating that there is 1 binding site for thymol on BSA. Calculated thermodynamic parameters for enthalpy (DeltaH), entropy (DeltaS), and Gibb's free energy (DeltaG) showed that the reaction was spontaneous and hydrophobic interactions were the main forces in the binding of thymol to BSA. The results of UV-vis spectroscopy and Arrhenius' theory showed the complex formation in the interaction of thymol and BSA. Negligible conformational changes in BSA by thymol were observed in fluorescence experiments, and the same results were also obtained from UV-vis studies. Results of molecular docking indicated that the subdomain IA of BSA was the binding site for thymol. PMID- 29600591 TI - Veteran-centred content in medical education. AB - BACKGROUND: Veterans have unique experiences that warrant special consideration in health care. Unfortunately, training in veteran-centred care has not been a clear focus of medical education, and only a very small proportion of medical schools include military cultural competency in their curricula. METHODS: We conducted an 80-minute focus group with six US veterans. Open-ended questions were used to elicit their perceptions of the health care that they receive, and how it can be improved. The audio-recording was transcribed verbatim and coded for thematic content. A phenomenological analytic approach was used to analyse the 31-page transcript and arrive at the final themes. RESULTS: Former service members from various periods of conflict (e.g. World War II, Vietnam, Persian Gulf) offered key insights about how to improve veterans' health care experiences. Veterans suggested that consideration of their previous military service would improve care. They lamented that the lack of military consciousness is a barrier to care. Finally, they suggested that clinicians pay close attention to the transition from service member to civilian, as reintegration to civilian life is a critical life experience. Training in veteran-centred care has not been a clear focus of medical education DISCUSSION: Veteran-centred care ensures optimal health care through ease of access to services, and through positive patient-provider interactions. Being aware of military culture can help providers to contextualise veterans' experiences and beliefs about health care seeking and illness management, particularly for invisible wounds of war, including traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD).

AB - A novel heteroannulation reaction between alpha-amino imides and in situ generated arynes has been developed for the synthesis of 2,2-disubstituted indolin-3-ones. An enantioselective total synthesis of the marine alkaloid (+) hinckdentine A was subsequently accomplished using this reaction as a key step. A catalytic enantioselective Michael addition of an alpha-aryl-alpha isocyanoacetate to phenyl vinyl selenone was employed for the construction of the enantioenriched alpha-quaternary alpha-amino ester. PMID- 29600594 TI - HBX protein promotes LASP-1 expression through activation of c-Jun in human hepatoma cells. AB - LIM and SH3 domain protein 1 (LASP-1) is known to participate in the progression of hepatocellular carcinoma (HCC). We previously showed that ectopic expression of hepatitis B virus (HBV) X protein (HBX) enhanced the expression of LASP-1, which promoted proliferation and migration of HCC cells. Here, we further demonstrated the molecular mechanism underlying upregulation of LASP-1, mediated by HBX, in HBV-infected HCC cells. Through a luciferase activity assay, we discovered that the LASP-1 promoter region regulated by HBX contained an AP-1 binding element in human hepatoma cells. Interestingly, c-Jun, one subunit of AP 1, was mainly responsible for activation, mediated by HBX, of the LASP-1 promoter. Furthermore, HBX was shown not only to interact with phosphorylated c Jun in HCC cells but also to activate c-Jun by increasing the activation of PI3 K/JNK signaling. Chromatin immunoprecipitation (ChIP) assay demonstrated that HBX was capable of binding to the LASP-1 promoter with c-Jun. Further, the expression levels of HBX were shown to be significantly positively correlated with that of LASP-1 and phosphorylatedc-Jun in HBV-related HCC tissues by immunohistochemistry analysis. In addition, the N-terminus of HBX was found to be responsible for the activation of c-Jun, as well as the expression of LASP-1. Taken together, these results suggest that HBX contributes to LASP-1 expression via the activation of c Jun to increase the promoter activity of LASP-1 in HBV-related HCC cells. PMID- 29600595 TI - The Tablets, Ring, Injections as Options (TRIO) study: what young African women chose and used for future HIV and pregnancy prevention. AB - INTRODUCTION: Preventing HIV and unintended pregnancies are key global health priorities. To inform product rollout and to understand attributes of future multipurpose prevention technologies (MPT) associated with preference and use, we evaluated three placebo delivery forms: daily oral tablets, a monthly vaginal ring, and two monthly intramuscular injections in TRIO, a five-month study among young Kenyan and South African women. METHODS: HIV-negative, sexually active, non pregnant women aged 18 to 30 were enrolled and randomized to use each placebo delivery form for one month (stage 1). Then, participants chose one product to use for two additional months (stage 2). We assessed safety, product ranking, choice, and use. We examined demographic and behavioural correlates of choice and, reciprocally, unwillingness to use in the future with logistic regression models. RESULTS: 277 women enrolled, 249 completed stage 1 and 246 completed stage 2. Median age was 23 years, 49% were Kenyan and 51% were South African. Three participants became pregnant during the study and one participant HIV seroconverted. There were 18 product-related adverse events, six tablets-related, 11 ring-related, and one injection-related. After trying each product, 85% preferred a TRIO product over condoms. Injections were chosen most (64%, 95% confidence interval (CI) 58%, 70%; p < 0.001), and by more South Africans than Kenyans (odds ratio (OR) 2.01, 95% CI: 1.17, 3.43; p = 0.01). There was no significant difference in choosing tablets versus ring (21%, 95% CI: 16%, 26% vs. 15%, 95% CI: 11%, 20%; p = 0.11). Tablet and ring adherence, based on direct observations and self-reports, improved over time. However, participants' self reported use of tablets did not match objective data from the electronic dose monitoring device. Participants were fully compliant with injections. CONCLUSION: In this population at risk for HIV and pregnancy, all participants agreed to choose and use a placebo MPT delivery form. A majority of participants preferred TRIO products to male condoms, an existing MPT. Injections were most liked and best used, however, they are years away from reaching the clinics. In the meantime, expanding the availability of tablets and giving access to rings can begin to fulfill the promise of choice for HIV prevention technologies and inform the development of suitable delivery forms as MPT.

AB - Dexmedetomidine is a selective alpha2 -adrenergic agonist used for patient sedation, while its enantiomer levomedetomidine has no sedative effects. As CE has been shown to be a powerful technique for enantiomer analysis, the aim of the study was the quality by design-based development of a CE-based limit test for the enantiomeric impurity levomedetomidine. The analytical target profile was defined that the method should be able to determine levomedetomidine with acceptable precision and accuracy at the 0.1% level. From initial scouting experiments, sulfated beta-cyclodextrin was selected as chiral selector. The critical process parameters were identified in a fractional factorial resolution V+ design, while a central composite face centered design and Monte Carlo simulations were used for defining the design space of the method. The selected working conditions were a 21.3/31.5 cm, 50 MUm id fused-silica capillary, a 50 mM sodium phosphate buffer, pH 6.5, containing 40 mg/mL sulfated beta-cyclodextrin, a capillary temperature of 17 degrees C and an applied voltage of 10 kV. Validation according to the ICH guideline Q2(R1) demonstrated repeatability and intermediate precision of content and migration time between 9.3 and 4.2% with accuracy in the range of 92.0 and 98.9%.

AB - Upon demyelination, transient expression of fibronectin precedes successful remyelination. However, in chronic demyelination observed in multiple sclerosis (MS), aggregates of fibronectin persist and contribute to remyelination failure. Accordingly, removing fibronectin (aggregates) would constitute an effective strategy for promoting remyelination. Matrix metalloproteinases (MMPs) are enzymes known to remodel extracellular matrix components, including fibronectin. Here, we examined the ability of MMPs to degrade fibronectin aggregates. Our findings reveal that MMP7 cleaved fibronectin aggregates resulting into a prominent 13 kDa EIIIA (16 kDa EDA)-containing fragment. MMP7 was upregulated during lysolecithin-induced demyelination, indicating its potential for endogenous fibronectin clearance. In contrast, the expression of proMMP7 was substantially decreased in chronic active and inactive MS lesions compared with control white matter and remyelinated MS lesions. Microglia and macrophages were major cellular sources of proMMP7 and IL-4-activated, but not IFNgamma+LPS activated, microglia and macrophages secreted significant levels of proMMP7. Also, conditioned medium of IL-4-activated macrophages most efficiently cleaved fibronectin aggregates upon MMP-activating conditions. Yet, coatings of MMP7 cleaved fibronectin aggregate fragments inhibited oligodendrocyte maturation, indicating that further degradation and/or clearance by phagocytosis is essential. These findings suggest that MMP7 cleaves fibronectin aggregates, while reduced (pro)MMP7 levels in MS lesions contribute to their persistent presence. Therefore, upregulating MMP7 levels may be key to remove remyelination-impairing fibronectin aggregates in MS lesions.

AB - Clathrate hydrates of CO2 have been proposed as potential molecular materials in tackling important environmental problems related to greenhouse gases capture and storage. Despite the increasing interest in such hydrates and their technological applications, a molecular-level understanding of their formation and properties is still far from complete. Modeling interactions is a challenging and computationally demanding task, essential to reliably determine molecular properties. First-principles calculations for the CO2 guest in all sI, sII, and sH clathrate cages were performed, and the nature of the guest-host interactions, dominated by both hydrogen-bond and van der Waals forces, was systematically investigated. Different families of density functionals, as well as pairwise CO2 @H2 O model potentials versus wavefunction-based quantum approaches were studied for CO2 clathrate-like systems. Benchmark energies for new distance-dependent datasets, consisting of potential energy curves sampling representative configurations of the systems at the repulsive, near-equilibrium, and asymptotic/long-range regions of the full-dimensional surface, were generated, and a general protocol was proposed to assess the accuracy of such conventional and modern approaches at minimum and non-minimum orientations. Our results show that dispersion interactions are important in the guest-host stabilization energies of such clathrate cages, and the encapsulation of the CO2 into guest free clathrate cages is always energetically favorable. In addition, the orientation of CO2 inside each cage was explored, and the ability of current promising approaches to accurately describe non-covalent CO2 @H2 O guest-host interactions in sI, sII, and sH clathrates was discussed, providing information for their applicability to future multiscale computer simulations.

PMID- 29600601 TI - Pelvic Artery Calcification Score Is a Marker of Vascular Calcification in Male Hemodialysis Patients. AB - Patients who undergo hemodialysis often suffer from cardiovascular disease (CVD), and evaluation of coronary artery calcification is extremely important. These evaluations are typically conducted using a noninvasive method including electron beam computed tomography (CT) or multi-detector CT, and the Agatston method to calculate the coronary artery calcification score (CACS). However, it is difficult to use for patients undergoing dialysis. Because patients undergoing dialysis is too strong in coronary artery calcification, and results become incorrect. Therefore, we were looking for a calcified evaluation place peculiar to a patients undergoing dialysis. We obtained pelvic artery calcification scores (PACS) using a 64-row multi-slice CT to assess the presence of calcification within a triangular space bordered by bordered by osseous structure. We used the Agatston method to calculate PACS. We compared male patients undergoing dialysis with male patients with normal renal function. Patients undergoing hemodialysis had a significantly higher incidence of pelvic artery calcification than normal controls (79.7% vs. 5.5%). In the dialysis group, CACS was 1660.2 (0-9056.1), and PACS was 48.8 (0-2943.1). We found a correlation between PACS and CACS and between PACS and dialysis period. We found penile artery calcification in male patients undergoing hemodialysis was more than normal controls, and it was possible to quantify PACS using the Agatston method. This study suggested the possibility that PACS became the vascular calcification evaluation method of the hemodialysis patient. PMID- 29600602 TI - Performance evaluation of extended depth of field microscopy in the presence of spherical aberration and noise. AB - Effectiveness of extended depth of field microscopy (EDFM) implementation with wavefront encoding methods is reduced by depth-induced spherical aberration (SA) due to reliance of this approach on a defined point spread function (PSF). Evaluation of the engineered PSF's robustness to SA, when a specific phase mask design is used, is presented in terms of the final restored image quality. Synthetic intermediate images were generated using selected generalized cubic and cubic phase mask designs. Experimental intermediate images were acquired using the same phase mask designs projected from a liquid crystal spatial light modulator. Intermediate images were restored using the penalized space-invariant expectation maximization and the regularized linear least squares algorithms. In the presence of depth-induced SA, systems characterized by radially symmetric PSFs, coupled with model-based computational methods, achieve microscope imaging performance with fewer deviations in structural fidelity (e.g., artifacts) in simulation and experiment and 50% more accurate positioning of 1-MUm beads at 10 MUm depth in simulation than those with radially asymmetric PSFs. Despite a drop in the signal-to-noise ratio after processing, EDFM is shown to achieve the conventional resolution limit when a model-based reconstruction algorithm with appropriate regularization is used. These trends are also found in images of fixed fluorescently labeled brine shrimp, not adjacent to the coverslip, and fluorescently labeled mitochondria in live cells. PMID- 29600603 TI - [Current research situation of nephrotoxicity of Chinese herbal medicine]. AB - To provide the basis for the future research on the nephrotoxicity of Chinese herbal medicine through systematic and comprehensive summary of all the Chinese herbal medicines which may lead to nephrotoxicity. Foreign resources included PubMed and Cochrane library, and domestic research resources was China Food and Drug Administration(CDFA) Adverse Drug Reaction Monitoring Center database. The databases were searched from establishment to January 1, 2017. There was no limitation on research type. 28 English studies were found, including 97 Chinese herbs or prescriptions with the risk of nephrotoxicity. The following six Chinese herbal medicines with the risk of nephrotoxicity had a large number of studies: aristolochic acid(5 studies), Tripterygium wilfordii(4 studies), Erycibe obtusifolia(2 studies), Rheum palmatum(2 studies), Ephedra sinica(2 studies), and Atractylodes lances(2 studies). The remaining 91 Chinese medicines were reported with risk of nephrotoxicity in only 1 study respectively. CDFA reported 16 Chinese herbal medicines with the risk of nephrotoxicity, including Ganmaoqing Pian(capsule), Zhenju Jiangya Pian, T. wilfordii preparation, Vc-Yinqiao Pian, Chuanhuning injection, Shuanghuanglian injection, Qingkailing injection, Lianbizhi injection, herbal decoction containing Aristolochiae Radix, Guanxin Suhe Wan, Shugan Liqi Wan, Ershiwuwei Songshi Wan, herbal decoction containing Aristolochia Fangchi, herbal granules containing root of Kaempfer Dutchmanspipe, Ganmaotong(tablets), and Longdan Xiegan Wan.

AB - To evaluate the quality of randomized controlled trials(RCT) on nephrotoxicity of Tripterygium wilfordii preparations according to the CONSORT HARMs statement. The report quality of each included study was evaluated according to the CONSORT HARMs statement, and the number of entries that comply with CONSORT HARMs statement was calculated in each study to evaluate the report quality on nephrotoxicity-related adverse reactions of T. wilfordii preparations and summarize the problems in domestic studies on nephrotoxicity-related adverse reactions. A total of 16 RCTs were included, with an average of 7 entries complying with CONSORT HARMs statement per study. The report of the nephrotoxic associated RCT of T. wilfordii preparations was of poor quality and the most non repeating entries included the following ones: using validated tools to report adverse effects, standards for coding of the adverse reactions, describing how and when to collect data on adverse reactions in Method, describing how adverse reactions are attributed to T. wilfordii, clearly stating who has reported the adverse reactions, describing the analysis method of adverse reactions, describing the method of collecting recurrent adverse reaction data, describing any subgroup analysis and exploratory analysis associated with the hazard. We suggest that the studies on adverse reactions of traditional Chinese medicine should strictly report the entries according to the CONSORT HARMs statement, and take the characteristics of traditional Chinese medicine into account to report the details of the Chinese medicine like compositions, dose, taking time, combined medication and the dialectical typology of research objects. PMID- 29600606 TI - [Application of evidence-based rapid review in studying nephrotoxicity of Tripterygium wilfordii preparation]. AB - To investigate the feasibility of applying the evidence-based rapid review in studying the nephrotoxicity of Tripterygium wilfordii preparation. We used four methods in relevant studies on the nephrotoxicity of T. wilfordii preparation. The first method had no limitation on any search terms, which was a traditional approach to retrieve systematic reviews. The second method limited the relevant search terms of T. wilfordii preparation to "all of CHMs containing T. wilfordii preparation approved by CFDA". The third method was to limit the relevant retrieval terms of nephrotoxicity as the "most frequently reported terms related to nephrotoxicity found in the study literature screening process in the early stage of systematic review". The fourth method was to limit the search terms relating to both T. wilfordii preparation and nephrotoxicity. Finally, the results of the last three search methods were compared with those of the first search method, and the feasibility of the rapid review method in the study for the nephrotoxicity of CHM was discussed. For the total number of literatures searched, the fourth method had the smallest number of literatures. For the number of articles in line with the inclusion criteria, the second method had the largest number of eligible literatures. For the type of literatures included, the forth method had a higher coincidence degree. The forth method was the best one, because it was not only consistent with the results, but also could minimize the workload. Rapid review is feasible in the study of nephrotoxicity of T. wilfordii.

AB - There are five kinds of fermented Cordyceps crude drug and their preparations that have been approved as medicine on the market. Since the initial strains of the crude drug were all isolated from natural Cordyceps sinensis, they have similar names, chemical components and even clinical applications. However, because of the different strain species and fermentation processes, there was significant difference in quality. As a result, they should be clearly distinguished in clinical use. Most of the products were researched and developed during the 1980s and 1990s, so there was difference in quality standards for different products, and their quality control levels of some products were not perfect. At present, some of the products are approved as Chinese medicine, others are approved as chemical drugs, with a confusion in products name, management and clinical application. In this paper, the approval numbers, quality standards and clinical applications, and current problems of these products were summarized and compared; some suggestions were put forward, such as standardizing the product name, unifying the management of approval number category, and increasing the specific quality control attributes, in order to provide reference for standard implementation, quality control and drug regulation for fermented Cordyceps crude drugs and their preparations.

AB - To investigate the differences of chemical compositions in Gynostemma pentaphyllum leaves prepared by different processing methods. Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to compare the chemical compositions between shade-dried processing and drum-dried processing. Forty six gypenosides were identified by control comparison, liquid chromatography-mass spectrometry(LC-MSn) fragmentation information, and literature data. The mass spectral peak area statistics was combined with principal component analysis(PCA), and the results showed that eight batches of Gynostemma pentaphyllum leaves samples were divided into two groups according to the two different processing methods; ten chemical compositions with significant differences were screened according to mass spectrum information combined with partial least-squares discriminant analysis(PLS-DA). The result showed that most parent nucleus of the gypenosides contained three to four glycosides in drum-dried samples, and one to two glycosides in the shade-dried samples. It was inferred from further MS analysis that desugarization of gypenosides was present to produce secondary glycosides with the effect of glucosidase in the shade-drying, thus resulting in difference in compositions. This study provided data support for harvesting, processing and quality control of Gynostemma pentaphyllum leaves.

AB - Nuciferin is the main active ingredients in Nelumbinis Folium, which was proved to have good hypolipidemic, antioxidative and anti-inflammatory bioactivities. Currently, in vivo pharmacokinetic studies of nuciferin showed different results based on different animal models. In vitro evaluation experiments were low-cost, stable and controllable. Biopharmaceutical classification system(BCS) was an effective and reliable in vitro simulation method to evaluate the bioavailability of oral drugs. It was a scientific framework for classifying drugs or active pharmaceutical ingredients(API) according to their solubility and impermeability in vitro. In the study, BCS was applied in an active ingredient in traditional Chinese medicine(TCM), which was consisted of numerous chemical components. To study the equilibrium solubility of nuciferine, ideal solution model, Ape blat model and polynomial model were adopted. The permeability was measured based on partition coefficient(logP) and distribution coefficient(logD). Besides, in vitro apparent permeabilities of Caco-2 cells and murine intestine tissues were evaluated. Nuciferine was classified as BCSI, since it had a good solubility and permeability in all methods under acidic conditions. However, in neutral and alkaline environments, nuciferine was classified as BCSIV by using everted intestinal sac. It indicated that the species of experimental animals has a significant influence on the absorption of nuciferine. This experiment can provide data support to the prediction in a complex environment(medicinal materials and absorbed parts). The application of BCS on TCM ingredients provided a new in vitro method to evaluate and screen out the druggability of TCM ingredients.

AB - Ginger juice, a commonly used adjuvant for Chinese materia medica, is applied in processing of multiple Chinese herbal decoction pieces. Because of the raw materials and preparation process of ginger juice, it is difficult to be preserved for a long time, and the dosage of ginger juice in the processing can not be determined base on its content of main compositions. Ginger juice from different sources is hard to achieve consistent effect during the processing of traditional Chinese herbal decoction pieces. Based on the previous studies, the freeze drying of ginger juice under different shelf temperatures and vacuum degrees were studied, and the optimized freeze drying condition of ginger juice was determined. The content determination method for 6-gingerol, 8-gingerol, 10 gingerol and 6-shagaol in ginger juice and redissolved ginger juice was established. The content changes of 6-gingerol, 8-gingerol, 10-gingerol, 6 gingerol, 6-shagaol, volatile oil and total phenol were studied through the drying process and 30 days preservation period. The results showed that the freeze drying time of ginger juice was shortened after process optimization; the compositions basically remained unchanged after freeze drying, and there was no significant changes in the total phenol content and gingerol content, but the volatile oil content was significantly decreased(P<0.05). Within 30 days, the contents of gingerol, total phenol, and volatile oil were on the decline as a whole. This study has preliminarily proved the feasibility of freeze-drying process of ginger juice as an adjuvant for Chinese medicine processing.

AB - The dynamic changes of active components in stems and leaves of Mentha Haplocalycis Herba(mint) at different harvest periods were investigated, and the optimum harvest time of mint was explored. In this study, hesperidin, diosmin, didymin and buddleoside were selected as flavonoids index components of mint, and the QAMS method was established to measure the contents of these flavonoids in mint. The contents of 4 flavonoid glycosides in the mint stems and leaves from three habitats harvested in different time were studied and evaluated comprehensively using statistical analysis and principal component analysis (PCA). The results showed that the contents of 4 components in the leaves are higher than that in the stems despite of habitats and harvest time, and they all exhibited dynamic changes along with the harvest periods within the same habitat. Three harvest periods in mid April, mid September and late October scored higher in comprehensive evaluation in Jiangsu region, the genuine producing area of Mentha Haplocalycis Herba. Combined with the yield and contents of active compounds, the optimum harvest time of mint in Jiangsu region was mid September and late October, which is basically consistent with the traditional harvesting periods.

AB - To study the effect and underlying mechanism of Mahuang Tang against influenza A virus in vitro, the influenza virus-infected Madin-Darby canine kidney(MDCK) cells were used as the carrier in this study to detect the median tissue culture infective dose(TCID50) of influenza A virus strains(A/PR8/34) on MDCK cells with cytopathic effect(CPE) assay. Blocking influenza virus invading host cells and anti-influenza virus biosynthesis were used as two different administration methods, and then the methyl thiazolyl tetrazolium(MTT) assay was utilized to determine the antiviral effective rate(ER), median efficacious concentration(EC50) and therapeutic index(TI) of Mahuang Tang. The quantitative Real-time polymerase chain reaction(RT-PCR) was used to measure virus load and the mRNA expression levels of TLR4, TLR7, MyD88 and TRAF6 in MDCK cells at 24, 48 h after the treatment. The experiment results indicated that TCID50 of A/PR8/34 for MDCK cells was 1*10-4.32/mL. The EC50 values of two different treatment methods were 4.92,1.59 g.L-1 respectively, the TI values were 12.53, 38.78 respectively, and when the concentration of Mahuang Tang was 5.00 g.L-1, ER values were 50.21%, 98.41% respectively, showing that Mahuang Tang can block influenza virus into the host cells and significantly inhibit their biosynthesis. Meanwhile, as compared with the virus group, the virus load was significantly inhibited in Mahuang Tang groups, and Mahuang Tang high and middle doses had the significant effect on decreasing the mRNA expression of TLR4, TLR7,MyD88 and TRAF6 at 24, 48 h after the treatment. It can be demonstrated that the mechanisms of Mahuang Tang against influenza A virus are related to the inhibition of influenza virus replication and the mRNA expression of correlative genes in TLR4 and TLR7 signaling pathways.

AB - Genistein is a kind of isoflavone compounds, also called phytoestrogens, with clinical effects on cardiovascular disease, cancer and postmenopausal-related gynecological diseases, and also has the potentiality in the prevention and treatment of Alzheimer's disease(AD). In this study, the protective effect of genistein on Abeta25-35-induced PC12 cell injury and effect on CaM-CaMKIV signaling pathway were observed to investigate its mechanism for AD. PC12 cells were cultured in vitro and then the safe concentration of genistein and the modeling concentration and optimal time point of administration of Abeta25-35 were screened by MTT assay. After being pretreated with different concentrations of genistein(25, 50, 100 MUmol.L-1) on PC12 cells, the AD model of PC12 cells was induced by Abeta25-35. Then the survival rate of cells was detected by MTT assay; morphological change of cells was observed under the inverted microscope, and apoptosis of cells was assessed by AO/EB fluorescence staining; the neuroprotective effects of genistein on AD cell model were observed and the optimal concentration of genistein was determined. Expressions of mRNA and protein levels of CaM, CaMKK, CaMKIV and tau were detected by qRT-PCR and Western blot assay, respectively. The results showed that as compared with the blank group, the cell survival rate was decreased; the cell damage and apoptosis were increased; and the expressions of mRNA and protein levels of CaM, CaMKK, CaMKIV and tau were increased in AD model group. Genistein could significantly improve the cell survival rate, reduce the cell damage and apoptosis of AD cell model, and significantly down-regulate the expressions of mRNA and protein levels of CaM, CaMKK, CaMKIV and tau of AD cell model. These results indicated that genistein has obviously neuroprotective effect on the AD cell model induced by Abeta25-35, and the mechanism may be related to the down-regulation of CaM-CaMKIV signaling pathway and Tau protein expression. PMID- 29600625 TI - [Effect of microRNA-34a/SIRT1/p53 signal pathway on notoginsenoside R1 delaying vascular endothelial cell senescence]. AB - This study aimed to investigate the effect of notoginsenoside R1 in delaying H2O2 induced vascular endothelial cell senescence through microRNA-34a/SIRT1/p53 signal pathway. In this study, human umbilical vein endothelial cells(HUVECs) were selected as the study object; the aging model induced by hydrogen peroxide(H2O2) was established, with resveratrol as the positive drug. HUVECs were randomly divided into four groups, youth group, senescence model group, notoginsenoside R1 group and resveratrol group. Notoginsenoside R1 group and resveratrol group were modeled with 100 MUmoL.L-1 H2O2 for 4 h after 24 h treatment with notoginsenoside R1(30 MUmoL.L-1) and resveratrol(10 MUmoL.L-1) respectively. At the end, each group was cultured with complete medium for 24 h. The degree of cellular senescence was detected by senescence-associated beta galactosidase(SA-beta-Gal) staining kit, the cell viability was detected by cell counting kit-8, the cell cycle distribution was analyzed by flow cytometry, and the cellular SOD activity was detected by WST-1 method in each group. The expressions of SIRT1, p53, p21 and p16 proteins in HUVECs were detected by Western blot. In addition, the mRNA expressions of miRNA-34a, SIRT1 and p53 in HUVECs were assayed by Real-time PCR. These results indicated that notoginsenoside R1 significantly reduced the positive staining rate of senescent cells, enhanced the cell proliferation capacity and intracellular SOD activity, decreased the proportion of cells in G0/G1 phase, and increased the percentage of cells in S phase simultaneously compared with the senescence model group. Moreover, notoginsenoside R1 decreased the mRNA expressions of miRNA-34a and p53 and the protein expression of p53, p21 and p16.At the same time, notoginsenoside R1 increased the protein and mRNA expressions of SIRT1. The differences in these results between the senescence model group and the notoginsenoside R1 group were statistically significant(P<0.05). However, there was not statistically significant difference in these results between the notoginsenoside R1 group and the resveratrol group. In conclusion, the senescence of endothelial cells induced by H2O2 can be used as a model for studying aging. Notoginsenoside R1 has an obvious anti-aging effect on vascular endothelial cells in this study. The possible mechanism is that notoginsenoside R1 can delay the senescence process of vascular endothelial cells induced by H2O2 by regulating microRNA-34a/SIRT1/p53 signal pathway.

AB - This paper aimed to investigate the effects of Jinwu Jiangu recipe total extract on the IL-17/STAT3 signals in rheumatoid arthritis synovial fibroblasts(RASF). The primary RASFs were cultured by tissue piece method in vitro, and divided into blank control group, Jinwu Jiangu recipe low dose group, Jinwu Jiangu recipe middle dose group, Jinwu Jiangu recipe high dose group, and tripterygium glycosides control group. They were then treated with corresponding serum free medium, different doses of Jinwu Jiangu recipe total extract(0.06, 0.6, 6.0 g.L 1), and tripterygium glycosides(0.03 g.L-1) respectively for 24 hours. The gene expression levels of RORalpha, RORgammat, and STAT3 mRNA were detected by polymerase chain reaction(PCR), and the protein activity of IL-17R and pSTAT3 were measured by Western blot assay. The results showed that as compared with blank control group, the expression levels of RORalpha, RORgammat, IL-17R and STAT3 mRNA in RASF were significantly declined(P<0.01). As compared with tripterygium glycosides control group, Jinwu Jiangu recipe total extract middle dose group and high dose group can down-regulate the expression levels of RORalpha, RORgammat, IL-17R and STAT3 mRNA(P<0.05), and the effect was more obvious in high dose group(P<0.01). As compared with blank control group, the protein expression levels of IL-17R and pSTAT3 in each treatment group were obviously decreased(P<0.01). As compared with tripterygium glycosides control group, Jinwu Jiangu recipe high dose group had more obvious effect in down regulating the protein expression of pSTAT3(P<0.01). Therefore, Miao medicine Jinwu Jiangu recipe total extract can down-regulate the expressions of RORalpha, RORgammat, and STAT3 mRNA, and inhibit the protein activity of IL-17R and pSTAT3 in RASF. PMID- 29600627 TI - [Huaier aqueous extract inhibits proliferation of human hepatoma SK-HEP-1 cells through up-regulation of autophagy]. AB - The purpose of this study was to investigate the effect of Huaier on autophagy of human hepatoma SK-HEP-1 cells and the effect of autophagy on the proliferation of SK-HEP-1 cells. CCK-8 assay was used to evaluate the effect of Huaier on the proliferation of SK-HEP-1 cells under different concentrations and different times. Acridine orange staining was used to measure the effect of Huaier on the autolysosome formation in SK-HEP-1 cells. Immunofluorescence assay was applied to examine the effect of Huaier on the expression and distribution of autophagy marker LC3 in SK-HEP-1 cells. In addition, LC3 expression was also checked by immunoblot analysis in the presence of Huaier. At last, the effects of Huaier in combination with autophagy inhibitor bafilomycin A1 on the proliferation of SK HEP-1 cells was detected by CCK-8 assay. The results showed that Huaier aqueous extract significantly inhibited the proliferation of human hepatoma SK-HEP-1 cells in a dose- and time-dependent manner. Huaier aqueous extract dramatically promoted the formation of autolysosome in SK-HEP-1 cells. Moreover, Huaier markedly increased the number and intensity of intracellular LC3 fluorescent puncta and up-regulated LC3-II expression. These data indicated that Huaier evidently activated autophagy of SK-HEP-1 cells. Additionally, autophagy inhibition significantly attenuated the sensitivity of SK-HEP-1 cells to Huaier treatment. Therefore, autophagy activation is involved in the inhibitory effects of Huaier on the proliferation of human hepatoma SK-HEP-1 cells.

AB - To explore the protective effect of naringin(Nar) on the injury of myocardium tissues induced by streptozotocin(STZ) in diabetic rats and the relationship with oxidative stress and endoplasmic reticulum stress(ERS), the male SD rats were intraperitoneally injected with streptozotocin(STZ, 60 mg.kg-1) to establish the diabetic rat model and then randomly divided into the type 1 diabetic rat group(T1DR), the low-dose Nar group(Nar25), the middle-dose Nar group(Nar50) and the high-dose Nar group(Nar100). The normal rats were designed as control group(Con). Nar25, Nar50, Nar100 groups were orally administered with Nar at the doses of 25.0, 50.0, 100.0 mg.kg-1 per day, respectively, while the normal group and the T1DR group were orally administered with saline. At the 8th week after treatment, fasting plasma glucose and heart mass index were measured. The pathological changes in myocardial tissues were observed by microscope. The cardiac malondialdehyde(MDA) level and superoxide dismutase(SOD) activities were measured. The gene and protein expressions of glucose-regulated protein 78(GRP78), C/EBP homologous protein(CHOP), cysteinyl aspartate-specific proteinase 12(caspase 12) were detected by qRT-PCR and Western blot. According to the results, compared with control group, the myocardial structure was damaged, the content of MDA was increased, while the activities of SOD were decreased(P<0.05) in T1DR group. GRP78, CHOP and caspase 12 mRNA and protein expressions were increased significantly in T1DR group(P<0.05, P<0.01). Compared with T1DR group, myocardial structure damage was alleviated in Nar treatment group. The content of MDA was decreased, while the activities of SOD were increased significantly. The mRNA and protein expressions of GRP78, CHOP and caspase 12 were increased, especially in middle and high-dose groups(P<0.05, P<0.01). After treatment with Nar for 8 weeks, myocardial structure damage was obviously alleviated in Nar treatment groups. The content of MDA was decreased, while the activities of SOD were increased significantly in myocardial tissues. The mRNA and protein expressions of GRP78, CHOP and caspase 12 were increased, especially in middle and high-dose groups(P<0.05, P<0.01). The findings suggest that Nar may protect myocardium in diabetic rats by reducing mitochondrial oxidative stress injuries and inhibiting the ERS-mediated cell apoptosis pathway.

AB - This study was aimed to investigate the effect and mechanism of Zhenwu Tang on AVP-V2R-AQP2 pathway in NRK-52E cells in vitro. Forty eight male SD rats were randomly divided into eight groups with 6 animals in each group. Distilled water or 22.68 g.kg-1.d-1 Zhenwu Tang(calculated by raw drug dosage meter) was given by gavage. Blood samples were collected by cardiac puncture, and the medicated serum was centrifuged from the blood by 3 000 r.min-1. NRK-52E cells were treated with different medicated serum or dDAVP. The condition of cell proliferation was detected by RTCA. The distribution of V2R and AQP2 in cells were detected by immunofluorescence. The expression of V2R, PKA and AQP2 were detected by Western blot and AQP2 mRNA level was detected by real-time PCR. Results showed that the level of AQP2 mRNA(P<0.01) and protein expression of V2R, PKA and AQP2(P<0.05, P<0.01, P<0.05) of Z7d group which was treated with Zhenwu Tang medicated serum for 24 h were significantly higher than that of normal rat serum group. And the expression level of V2R, p-AQP2 and AQP2(P<0.01, P<0.05, P<0.01) of Z7d+dDAVP group were significantly increased comparing to normal rat serum group. The results indicate that the applying of Zhenwu Tang medicated serum could increase the expression level of V2R, PKA and AQP2 which exist in AVP-V2R-AQP2 pathway in NRK-52E, and there is synergistic effect between Zhenwu Tang medicated serum and dDAVP. So the pathway of AVP-V2R-AQP2 may be one of the mechanism for which Zhenwu Tang regulate balance of water transportation.

PMID- 29600631 TI - [Exploring Chinese medicine and Western medicine group modules in acute phase of ischemic stroke disease]. AB - Under the theoretical guidance of "combination of disease and syndrome, correspondence between syndrome and prescription, and dynamic space-time", 11 135 acute ischemic stroke patients were collected from hospital information system(HIS) of many 3A grade hospitals of traditional Chinese medicine. Complex network analysis was adopted to obtain the core syndrome elements in different periods of acute ischemic stroke patients, and it was found that the core syndrome elements were blood stasis syndrome, phlegm, endogenous wind, Yin deficiency, Qi deficiency, heat, hyperactivity of liver Yang, liver, and kidney of patients in hospital for the first day, and during 8-14 d in hospitalization, the core syndrome elements were blood stasis, phlegm, Yin deficiency, Qi deficiency, endogenous wind, hyperactivity of liver Yang, liver, and kidney. The data with "improved" and "cured" treatment outcomes were adopted for complex network analysis and correlation analysis to identify the Chinese and Western medicine group modules in patients with different disease conditions in different phases after hospitalization. It was found that the Chinese and Western medicine modules within 14 d after hospitalization mainly included "blood-activating and stasis-dissolving module "consisted by "anti-platelet drug + circulation improving medicine(or anticoagulant drug and anti-fibrinogen drug, et al) + blood activating and stasis-dissolving drugs", as well as "stasis-dissolving and phlegm reducing module" consisted by "anti-platelet drugs + circulation-improving medicine(or anticoagulant drug and anti-fibrinogen drug, et al) + phlegm refreshing drug". The core Chinese and Western medicine modules in patients with urgent and general conditions within 7 d after hospitalization mainly used "blood activating and stasis-dissolving module" and "stasis-dissolving and phlegm reducing module". Three or more Chinese medicine and Western medicines module with more than 1% utilization rate was not found in the patients with critical disease condition in admission. The urgent, general and critically ill patients in admission mainly used "blood-activating and stasis-dissolving module" in 8-14 d. From the real world medical big data research, it was found that the combined use of Chinese and Western medicines were consistent with "combination of disease and syndrome, correspondence between syndrome and prescription, and dynamic space time" theory, and multiple multidimensional dynamic Chinese medicine and Western medicine group modules of "patient-syndrome-drug-time-effective" at the acute ischemic stroke stage were dug out, forming the method of Chinese and Western medicine combination research based on electrical medical big data.

PMID- 29600633 TI - [Herbal textual research on Chinese medicine "Huangjing" (Polygonati Rhizoma)and some enlightenments]. AB - To clarify the change and development of the original plants, medicinal organs, traditional functions, resource distribution of "Huangjing"(Polygonati Rhizome), a traditional Chinese medicine, we investigated Polygonatum species on the ancient Chinese herbal texts. The name of "Nuwei" was first carried out in the book of Sheng Nong's Herbal Classic. Its effects included two aspects: one was similar to "Weirui"(Polygonati Odorati Rhizome, "Yuzhu"), that was tonifying, nourishing one's vitality, removing wind and dampness, settling five organs, making body lightness, keeping longevity and not being hungry; the second was alike to "Huangjing" recorded in the book of Ming Yi Bie Lu(Appendant Records of Famous Physicians). Specifically, "Weirui" possesses the therapeutic effect of "Nuwei", while "Huangjing" possesses the tonic effect of " Nuwei". Thereafter, the following ancient Chinese herbal texts kept those two names and function records. Accordingly, we hold the point of view that "Huangjing" was first carried out in the book of Sheng Nong's Herbal Classic in the synonym of "Nuwei". "Yuzhu" included the "Huangjing" in ancient herbal text before Qing Dynasty, that was further confirmed by the research on change and development of the original plants. The identification between "Yuzhu" and "Huangjing" was based on the shape of rhizome and size before early Tang Dynasty. The shape was a key character and used up to now, but size was not reasonable. The opposite phyllotaxy was an important character of authentic "Huangjing" from Tang to Qing Dynasty. The seedling of Polygonatum sibiricum and P. kingianum, the adult plant of P. cyrtonema with alternate leaves were misused as "Yuzhu"("Nuwei" and "Weirui") at that time. Therefore, both "Yuzhu" and "Huangjing" should be used as key words during the search of ancient prescriptions and development of new drugs and health foods. The leaves, flowers, fruits and seedlings could be used as food or medicine other than the rhizomes in ancient China, but they haven't been developed in modern times. The culture of "Huangjing" had a long history starting with Tang Dynasty, which was recorded in Tang poetry. Then in Ming Dynasty, the culture method was described in Compendium of Materia Medica, that was cutting the rhizomes into 2 feet, planting sparsely(they would be grown densely in the next year), or sowing the seeds. The harvesting and processing were first recorded in Ming Yi Bie Lu: "harvest the roots in February, dry in the shade". Then the processing method was changed to "steaming and drying in the sun, repeatedly for nine times" in Shi Liao Ben Cao(Dietetic Materia Medica) and "harvesting in August as well" in Ben Cao Tu Jing(Commentaries on the Illustrations). No breakthrough has been taken in the breeding of cultivars and key cultivation technologies yet. As to the geo-authentic habitats, Mount Songshan and Maoshan were firstly recorded as the best producing areas of "Huangjing" in Ben Cao Tu Jing. But Maoshan, Jiangsu province and Mount Songshan, Henan province, are not main producing areas in modern China. Consequently, the plantation plan of Polygonati Rhizome needs further study.

AB - To identify the precious bile powder and its adulterants by DNA barcoding, and establish its standard experimental process to ensure the safe and effective utilization. Total twelve sequences from samples of bear bile powder which come from Ursus thibetanus for DNA extraction, PCR(polymerase chain reaction) and sequence, then using CodonCode Aligner V 7.0.1 shear primer region to obtain COI sequence. The COI sequences of U. arctos and their adulterants were obtained from GenBank. MEGA7.0 software was applied for analyzing mutation, calculating intraspecific and interspecific K2P(Kimura 2-Parameter) genetic distance and constructing the Neighbor-joining tree(NJ). The results showed that the maximum K2P genetic distance of bear bile powder of U. thibetanus and U. arctos are far less than minimum K2P genetic distance within its adulterants species, and the results of NJ tree demonstrated that each species could be distinguished from the counterfeits obviously. DNA barcoding is a safe, convenient and reliable technique for species identification, and it is important to establish the standard sequence of COI sequences for animal medicines.

AB - ABC efflux proteins are a kind of transporters mediating diversified endogenous and exogenous efflux protein substrates across the plasma membrane by depending on the chemical energy released by ATP hydrolysis. As a vitally important functional membrane, it is widely found in various tissues and organs. The drug changes the expressions and/or functions of the transport proteins, which will affect the disposal process of substrate drugs corresponding to transporters in vivo, and finally lead to the pharmacokinetic interactions. The efflux proteins take part in the absorption, distribution, metabolism and excretion of drugs, and mainly consist of P-glycoprotein(P-gp), multidrug resistance associated protein(MRP) and breast cancer resistance protein(BCRP). The induction effect or inhibition effect of drugs on efflux protein plays a greatly significant role in the drug interaction produced by the compatibility of traditional Chinese medicine, which may be one of the important mechanisms of the theory of seven features of compatibility. In this article, the effects of seven features of compatibility on the ABC efflux transporters were reviewed, in order to reveal the roles of efflux protein in the herb-pairs compatibility, and provide new ideas for the mechanism and rationality of herb compatibility.

AB - According to the previous results from transcriptome analysis of Ligustrum quihoui, a glycosyltransferase gene(xynzUGT) was cloned by rapid amplification of cDNA ends(RACE). The full length cDNA of xynzUGT was 1 598 bp, consisting of 66 bp 5'-UTR, 1 440 bp ORF and 92 bp 3'-UTR. The ORF encoded a 480 amino-acid protein(xynzUGT) with a molecular weight of 54 826.67 Da and isoelectric point of 5.82. The structure of enzyme was analyzed by using bioinformatics method, the results showed that the primary structure contained a highly conserved PSPG box of glycosyltransferase, the secondary structure included alpha helix(38%), beta sheet(12.1%) and random coil(49.9%), and tertiary structure was constructed by peptide chain folding to form two face-to-face alpha/beta/alpha domains(often referred to as a Rossmann domains), between which a substrate binding pocket is sandwiched. The phylogenetic tree analysis indicated that xynzUGT might catalyze glycosylation of phenylpropanoids, such as tyrosol. Further simulation experiment of molecular docking between enzyme and tyrosol showed that Gly138 and Ser285 located in the binding pocket interacted with tyrosol by hydrogen bonding. SDS PAGE analysis exhibited that the prokaryotic expression system successfully expressed recombinant xynzUGT with molecular weight of 58 370.57 Da, but it exists in the form of non-soluble inclusion bodies. Using the molecular chaperone and enzyme co-expression method, the soluble expression was promoted to some extent. The above works laid the foundation for further studying on enzymatic reaction in vitro and clarifying the functional mechanism of enzyme.

AB - GAPDH(glyceraldehyde-3-phosphate dehydrogenase) gene is a key enzyme gene in carbohydrate metabolism and always used as reference gene. To clarify and complete the biosynthetic pathway of polysaccharide, the GAPDH gene in Codonopsis pilosula, named CpGAPDH, was cloned according to the transcriptome of pilosula, using the GAPDH gene in potato as query. The CpGAPDH contained a 1 014 bp open reading frame(ORF) and encoded a protein with 337 amino acids. Bioinformatic analysis clearly suggested that CpGAPDH shared high similarity with GAPDH among other plants, and had the closest relatives to potato and danshen. The predicted protein did not have signal peptide, which indicated that it might be located in the cytoplasm. According to the existing of several phosphorylation sites and the conserved domains analysis, we predicted that it belonged to Gp_dh_N superfamily. Prokaryotic expression showed that the recombinant expressed a 44.3 kDa protein, which was corresponding to the theoretical relative molecular mass. However, the relative transcript level of the CpGAPDH did not have significant differences in different tissues and roots at different developmental stages of pilosula. Moreover, the stability of the CpGAPDH was analyzed by BestKeeper, geNorm, and NormFinder and RefFinder software, which showed that the CpGAPDH was more stable and could be used as a new reference gene. All these lay a foundation for the expression analysis of the gene relative to the polysaccharide synthesis.

AB - Chorismate synthase(CS, EC:4.2.3.5) catalyses 5-enolpyruvy-shikimate-3-phosphate to form chorismate, which is the essential enzyme for chorismate biosynthesis in organisms. The amino acid sequences of CS from 79 species of higher plants were reported in GenBank at present. 125 amino acid sequences of CS from Baphicacanthus cusia and other 78 species of plants were predicted and analyzed by using various bioinformatics software, including the composition of amino acid sequences, signal peptide, leader peptide, hydrophobic/hydrophilic, transmembrane structure, coiled-coil domain, protein secondary structure, tertiary structure and functional domains. The phylogenetic tree of CS protein family was constructed and divided into eight groups by phylogenetic analysis. The homology comparison indicated that B. cusia shared a high homology with several plants such as Sesamum indicum, Nicotiana tabacum, Solanum tuberosum and so on. The open reading frame(ORF) of all samples is about 1 300 bp, the molecular weight is about 50 kDa, the isoelectric point(pI) is 5.0-8.0 which illustrated that CS protein is slightly basic. The ORF of CS we cloned in B. cusia is 1 326 bp, the amino acid residues are 442, the molecular weight is 47 kDa and pI is 8.11. The CS in B.cusia showed obvious hydrophobicity area and hydrophilicity area, no signal peptide, and may exists transmembrane structure areas. The main secondary structures of CS protein are random coil and Alpha helix, also contain three main structural domains which are an active structural domain, a PLN02754 conserved domain and a FMN binding site. The acquired information in this study would provide certain scientific basis for further study on structure-activity relationship and structure modification of CS in plants in the future.

AB - The present study compared active ingredients of tea from different sources to select tea type and the fraction of tea extracts for the highest anti hyperglycemic activity, and to verify anti-hyperglycemic activity of the selected tea extract. Tea extracts were separated and enriched by molecular weight using ultra-filtration technology. The extracts were first screened by alpha glucosidase inhibition assay, followed by using a rat inverted intestine sac system to measure the effect on glucose transport. Both alloxan-induced diabetic rat model and high-fat diet combined with streptozotocin-induced rat diabetes mellitus model were used to study the effects of active components on blood glucose, body weight, insulin resistance. The experimental results showed that the different kinds of tea extracts had different inhibitory effects on alpha glucosidase, and the inhibitory effect of tea extract E on alpha-glucosidase was stronger. The effects of different components of tea extract E also varied greatly, of which Fraction AN protein had stronger inhibitory effect on alpha glucosidase than other fragments, and Fraction AN protein had a strong inhibitory effect on glucose transport, reduced blood sugar and normalized insulin secretion in diabetic rats. The results suggest that a glycol-protein fraction(AN) from the extracts might be responsible for the anti-hyperglycemic activity of tea polysaccharides. The AN glycol-protein fraction has strong inhibitory effects on both alpha-glucosidase activity and glucose transport by the small intestine. It also reduced blood glucose level and normalized insulin secretion in diabetic rats, and has a protective effect on diabetic rats.

AB - The aim of this research is to investigate the effects of paeoniflorin and menthol on the physiological function of Calu-3 cell membrane during the transport of puerarin. Calu-3 cell was used as the in vitro cell model to simulate nasal mucosa tissues, and the cell membrane fluidity, Na+-K+-ATPase activity and Ca2+-ATPase activity were detected by fluorescence recovery after photobleaching(FRAP) and ultramicro enzyme activity testing, in order to explore the mechanism of compatible drugs on promoting puerarin transport. The results showed that when puerarin associated with low, middle and high concentration of menthol or both paeoniflorin and menthol, the fluorescence recovery rate was increased significantly, while Na+-K+-ATPase activity had no significant change and Ca2+-ATPase activity was enhanced significantly as compared with puerarin alone. Therefore, it was concluded that menthol had the abilit? of promoting the transport and the mechanism might be related to increasing membrane fluidity and activating Ca2+-ATPase.

AB - Based on the fact that chromogenic reaction of blue complex, a reaction product which can be dissolved in organic solvents, can be realized by polyethoxy and ammonium thiocyanate in tween 80, a rapid and accurate way for the determination for tween 80 in pharmaceutical adjuvant was established in this study, providing reliable technical means for quality control of traditional Chinese medicine injections. Based on the study of reaction kinetics, chromogenic reaction temperature and time, as well as extraction of organic solvents and other key conditions were optimized, and Kumu injection was used as the test material for method validation and applicability investigation. It was finally determined that 3 mL ammonium thiocyanate solution was added in the sample solution, and the reaction was carried out in a boiling water bath for 2 h. After cooling to room temperature, 5 mL of dichloromethane was added to extract the chromogenic product. The absorbance value was measured at the wavelength of 623 nm to calculate the tween 80 content in the sample. Under optimized conditions, tween 80 solution showed a good linear relationship with the absorbance in the range from 0.8 mg to 3.0 mg. The linear regression equation was y=0.258x-0.047. The correlation coefficient r was 0.999 6. Under the experimental conditions, the average recovery was 99.66%, and the precision RSD was less than 2.0%. The results showed that this method can quickly and accurately determine the content of tween 80 in Kumu injection, and it could be applicable to the quality control of traditional Chinese medicine injections.

AB - Magnetic molecularly imprinted polymers(MMIPs) were prepared with ZL006 as template, acrylamide(AA) as the functional monomer, and acetonitrile as pore forming agent; then Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscopy(SEM) were used to characterize their forms and structures. Simultaneously, the MMIPs prepared previously were used as sorbents for dispersive magnetic solid phase extraction(DSPE) to capture and identify potential nNOS-PSD-95 uncouplers from extracts of Trifolium pratense and the the activities of the screened compounds were evaluated by the neuroprotective effect and co-immunoprecipitation test. The experiment revealed that the successfully synthesized MMIPs showed good dispersiveness, suitable particle size and good adsorption properties. Formononetin, prunetin and biochanin A were separated and enriched from Trifolium pratense by using the MMIPs as artificial antibodies and finally biochanin A was found to have higher cytoprotective action and uncoupling action according to the neuroprotective effect and co-immunoprecipitation test.

AB - Glioblastoma is a common brain tumor and the overall survival rate of the patients is very low, so it is an effective way to develop the potential chemotherapy or adjuvant chemotherapy drugs in glioblastoma treatment. As a well known antimalarial drug, artesunate(ARTs) has clear side effects, and recently it has been reported to have antitumor effects, but rarely reported in glioblastoma. Different concentrations of ARTs were used to treat the glioblastoma cells, and then the inhibitory effect of ARTs on glioblastoma proliferation was detected by MTT assay; Ki67 immunofluorescence assay was used to detect the proliferation of cells; Soft agar experiment was used to explain the clonal formation abilities in vitro; Flow Cytometry was used to detect the cell cycle; and Western blot assay was used to determine the expression of key cell cycle protein. MTT assay results indicated that ARTs-treated glioblastoma cell A172, U251, U87 were significantly inhibited in a time-and-dose dependent manner as compared to the control group(DMSO treatment group). Soft agar experiment showed that ARTs could significantly reduce the clonal formation ability of glioblastoma. Furthermore, Flow cytometry analysis showed that ARTs could obviously increase the cell proportion in G0/G1 phase and reduce the cell proportion in S phase. Western blot results showed that the expressions of cell cycle-related proteins CDK2, CDK4, cyclin D1 and cyclin B1 were all obviously down-regulated. Above all, ARTs may inhibit the proliferation of glioblastoma cells by arresting cell cycle in G0/G1 phase through down-regulating the expression of CDK2, CDK4, cyclin D1, cyclin B1. These results may not only provide a novel method for rediscovering and reusing ARTs but also provide a new potential drug for treating glioblastoma.

AB - This paper aimed to investigate the antibacterial activity of flowers and leaves from Paeonia rockii, screen antibacterial compounds and predict targets of antibacterial to explore its multi-component, multi-target antibacterial mechanism. In this study, minimal inhibitory concentration(MIC) of seven strains of Staphylococcus aureus, S. epidermidis, Bacillus subtilis, B. cereus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were determined by microdilution method. Uniprot databases was used to find the antibacterial targets, and RCSB was used to identify targets associated with antimicrobial activity as docked receptor proteins. The candidate active ingredients from flowers and leaves of P. rockii were identified by database such as PubChem. The ligands were constructed by ChemDraw, Avogadro and Discovery Studio Visualizer. QuickVina 2.0 software was used to molecular docking. Besides, the Cytoscape 3.5.1 software was used to construct activity compounds of flowers and leaves from P. rockii ingredients-targets network, and Uniprot software was used to analyze gene ontology and KEGG pathway. In vitro antibacterial experiments found antibacterial effect of the flowers and leaves from P. rockii, especially methanol extraction of flowers has the strongest antibacterial effect. The network pharmacology indicated that total 29 activity ingredients and their 18 targets were screened in flowers and leaves from P. rockii. Comparison of the active ingredients and the number of antimicrobial target networks, it is predicted that the antibacterial components are mainly flavonoids and phenolic acids and main mechanism of antibacterial is to inhibit the synthesis of bacterial proteins. In this study, potential antibacterial activity of flowers and leaves from P. rockii has be found by antibacterial experiments in vitro and network pharmacology screening. And this study provides new clues for further basic study on the antibacterial agents of flowers and leaves from P. rockii.

AB - This study aimed to observe the general state and changes in pathophysiological indexes of multiple cerebral infarction rat model with Qi-deficienty and Blood stasis syndrome. Rats were randomly divided into 4 groups(with 30 in each group): the normal group, the sham group, the model group and the Yiqi Huoxue recipe group. Rats in the model group and Yiqi Huoxue group were provided with interruptable sleep deprivation for 7 days before the multiple cerebral infarction operation, and followed by another 4 weeks of sleep deprivation; rats in the Yiqi Huoxue group were intragastrically administrated with drug at a dose of 26 g.kg-1, once a day for 4 weeks. The general state was observed, and the pathophysiological indexes were measured at 48 h, 2 weeks and 4 weeks after administration. The results showed that rats in the normal group and the sham group represented a good general state and behaviors, with a normal morphological structure of brain tissues; rats in the model group featured yellow fur, depression, accidie, loose stools and movement disorder, with obvious brain histomorphological damage, which became aggravated with the increase of modeling time; rats in the Yiqi Huoxue group showed release in the general state and above indexes. Compared with the sham group at three time points, rats in the model group showed decrease in body weight, exhaustive swimming time and RGB value of tongue surface image, and increase in whole blood viscosity of the shear rate under 5, 60 and 150 S-1, reduction in cerebral cortex Na+-K+-ATPase, Ca2+-ATPase activity and contents of 5-HT, rise in TXB2 levels and decline in 6-keto-PGF1a in serum(P<0.05, P<0.01). Compared with the model group, rats in the Yiqi Huoxue group showed alleviations in the above indexes at 2 w and 4 w(P<0.05, P<0.01). The results showed that the characterization and pathophysiological indexes in the multiple cerebral infarction rat model with Qi-deficiency and blood-stasis syndrome were deteriorated; Yiqi Huoxue recipe could significantly alliviate the abnormal conditions, which suggested of the model was stable and reliable and the pathophysiologic evolutionary mechanism might be related to energy metabolism dysfunction, vasoactive substance abnormality and changes in neurotransmitters. PMID- 29600657 TI - [Effect of leech on lipid metabolism and liver in hyperlipidemia rats]. AB - To explore the effect of leech on lipid metabolism and liver function in hyperlipidemia rats and the possible mechanism, biochemical analyzer was used to examine the regulation of leech on levels of serum triglycerides(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), and high-density lipoprotein cholesterol(HDL-C). The levels of ALT and AST in serum were detected by ELISA. The proteins expression of ACAT-2, Fas and HMGCR in liver tissue was detected by Western blot. The weight of body and liver were weighed, and liver index was calculated. Oil red O staining was used to observe the lipid accumulation in liver tissue of rats by light Microscope. The results showed that leech could decrease the levels of TC, LDL-C obviously, and increase HDL-C, decrease the levels of ALT, AST and the liver index, down-regulate the proteins expression of ACAT-2, Fas and HMGCR. And oil red O staining indicated that the lipid accumulation was less in the liver tissue of the rats intervented by leech. These data indicated that leech may affect the expression of ACAT-2, Fas and HMGCR in liver tissue to reduce the synthesis of cholesterol and fatty acid, and promote the cholesterol transforming, then regulate lipid metabolism to decrease the levels of serum lipid, and reduce lipid accumulation in liver tissue and ease liver injury of rats, then slowing down the process of nonalcoholic fatty liver disease(NAFLD) in hyperlipidemia rats. PMID- 29600658 TI - [Protective effect of Dendrobium candidum on isoproterenol induced cardiac hypertrophy in rats]. AB - To study the effect and mechanism of Dendrobium candidum on isoproterenol-induced myocardial hypertrophy in rats, 60 healthy SD rats(30 males and 30 females) were randomly divided into 5 groups(12 in each group): normal group, model group, three D. candidum preventive administration groups(0.09, 0.18, 1.1 g.kg-1). Except for the normal group, rats of other groups were injected back subcutaneously with ISO(5 mg.kg-1) for 10 consecutive days. At the same time, preventive administration groups began to give different doses of the sample for 30 days and model group began to give normal saline. Left ventricular systolic pressure(LVSP) was measured in each group by common carotid artery cannulation, and the left ventricle(LW)/tibia length, heart weight index(HWI) and myocardial hydroxyproline(Hydro) content were calculated. Myocardial tissue HE staining and Masson staining were used to observe the myocardial structure and the degree of myocardial fibrosis respectively. Atrial natriuretic peptide(ANP), brain natriuretic peptide(BNP), and cardiac troponin I(cTN-I) concentration were measured by enzyme-linked immunosorbent assay(ELISA). The results showed that as compared with the normal group, the levels of ANP, BNP and cTN-I in plasma were significantly increased in ISO-induced hypertrophic rats; as compared with the model group, D. candidumcan inhibit ISO-induced ventricular pressure and ventricular hypertrophy, reduce myocardial collagen synthesis, improve myocardial fibrosis and ventricular remodeling, and significantly down-regulate ANP, BNP and cTN-I levels in plasma. This study shows that D. candidum has a protective effect on isoproterenol-induced cardiac hypertrophy.

AB - This study aimed to investigate the possible sensitivity of Astragalus polysaccharides, in order to improve the chemosensitivity of cervical cancer HeLa cells to cisplatin by regulating the cell autophagy, and explore its possible mechanism. In this study, HeLa cells were divided into control group, cisplatin group, Astragalus polysaccharide group, and Astragalus polysaccharide combined with cisplatin group. MTT assay was used to detect the proliferation of cervical cancer HeLa cells. Flow cytometry was used to detect the apoptosis and cycle of HeLa cells in each experimental group. RT-PCR was used to detect the mRNA expression of autophagy-related proteins beclin1, LC3II and p62. The expression levels of autophagy-related proteins beclin1, LC3II, LC3I and p62 were detected by WB method. MTT results showed that compared with the control group, the proliferation of HeLa cells was significantly inhibited in each administration group(P<0.05), and the inhibitory effect of the combination group was more significant(P<0.01). The apoptotic rate of HeLa cells was significantly increased(P<0.05), and the apoptotic rate of the combination group was significantly increased(P<0.01) compared with the control group(P<0.05).In conclusion, G0/G1 phase showed the most significant differences between the two groups. RT-PCR and WB results showed that the gene and protein expressions of beclin1 and LC3II were up-regulated, while the gene and protein expressions of p62 were down-regulated compared with the control group. The above-mentioned changes in the combination group were more significant. Through the analysis of the above experimental results, it is speculated that Astragalus polysaccharides may increase the sensitivity of cervical cancer HeLa cells to cisplatin by regulating the cell autophagy. Its possible mechanism of action is correlated with the up-regulation of autophagy-related proteins beclin1, the promote the conversion from LC3I to LC3II, the down-regulation of labeled protein p62, and the enhancement of HeLa cell autophagic activity, thereby increasing the sensitivity of HeLa cells to cisplatin chemotherapy.

AB - Two types(A model and B model) of articular cartilage defect models were prepared by using adult New Zealand white rabbits. A model group was applied by drilling without through subchondral bone, whose right joint was repaired by composite scaffolds made by seed cell, gum-bletilla as well as Pluronic F-127, and left side was blank control. B model group was applied by subchondral drilling method, whose right joint was repaired by using composite scaffolds made by gum-bletilla and Pluronic F-127 without seed cells, and left side was blank control. Autogenous contrast was used in both model types. In addition, another group was applied with B model type rabbits, which was repaired with artificial complex material of Pluronic F-127 in both joint sides. 4, 12 and 24 weeks after operation, the animals were sacrificed and the samples were collected from repaired area for staining with HE, typeIIcollagen immunohistochemical method, Alcian blue, and toluidine blue, and then were observed with optical microscope. Semi-quantitative scores were graded by referring to Wakitanis histological scoring standard to investigate the histomorphology of repaired tissue. Hyaline cartilage repairing was achieved in both Group A and Group B, with satisfactory results. There were no significant differences on repairing effects for articular cartilage defects between composite scaffolds made by seed cell, gum-bletilla and Pluronic F-127, and the composite scaffolds made by gum-bletilla and Pluronic F 127 without seed cell. Better repairing effects for articular cartilage defects were observed in groups with use of gum-bletilla, indicating that gum-bletilla is a vital part in composite scaffolds material.

Computer retrieval was conducted in Medline, EMbase, the Web of Science, Clinical Trials. Gov, the Cochrane Library, CNKI, VIP, WanFang Data and CBM to collect relevant information. The papers were then screened according to inclusion and exclusion criteria. A total of 234 papers were included in this study, including 164 randomized controlled trials, 7 quasi-randomized controlled trials, 8 non randomized controls, 56 case series, and 1 cohort study. The patients were only treated with Guizhi Fuling Jiaonang in 56 studies, and Guizhi Fuling Jiaonang was combined with other drugs in 178 studies. The total ADRs/AEs incidence was 1.99% in single use of Guizhi Fuling Jiaonang, and 8.21% in combined use, but showing no severe adverse reactions. Gastrointestinal system damage was most common in mild ADRs. In this study, it was found that the overall safety of Guizhi Fuling Jiaonang was acceptable. The direct evidences of the drug's safety case reports were systematically analyzed in this study, but the mechanism study on the safety of the drug after marketing or the prospective long-term clinical observation study was not sufficient, so the further studies on the safety of drug use should be conducted in order to provide better guidance for clinical medication. PMID- 29600662 TI - [Methodological quality and reporting quality evaluation of randomized controlled trials published in China Journal of Chinese Materia Medica]. AB - To evaluate the methodological quality and reporting quality of randomized controlled trials(RCTs) published in China Journal of Chinese Materia Medica, we searched CNKI and China Journal of Chinese Materia webpage to collect RCTs since the establishment of the magazine. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of RCTs. The CONSORT 2010 list was adopted as reporting quality evaluating tool. Finally, 184 RCTs were included and evaluated methodologically, of which 97 RCTs were evaluated with reporting quality. For the methodological evaluating, 62 trials(33.70%) reported the random sequence generation; 9(4.89%) trials reported the allocation concealment; 25(13.59%) trials adopted the method of blinding; 30(16.30%) trials reported the number of patients withdrawing, dropping out and those lost to follow-up;2 trials (1.09%) reported trial registration and none of the trial reported the trial protocol; only 8(4.35%) trials reported the sample size estimation in details. For reporting quality appraising, 3 reporting items of 25 items were evaluated with high-quality,including: abstract, participants qualified criteria, and statistical methods; 4 reporting items with medium-quality, including purpose, intervention, random sequence method, and data collection of sites and locations; 9 items with low-quality reporting items including title, backgrounds, random sequence types, allocation concealment, blindness, recruitment of subjects, baseline data, harms, and funding;the rest of items were of extremely low quality(the compliance rate of reporting item<10%). On the whole, the methodological and reporting quality of RCTs published in the magazine are generally low. Further improvement in both methodological and reporting quality for RCTs of traditional Chinese medicine are warranted. It is recommended that the international standards and procedures for RCT design should be strictly followed to conduct high-quality trials. At the same time, in order to improve the reporting quality of randomized controlled trials, CONSORT standards should be adopted in the preparation of research reports and submissions. PMID- 29600663 TI - [Traditional Chinese Medicine data management policy in big data environment]. AB - As traditional data management model cannot effectively manage the massive data in traditional Chinese medicine(TCM) due to the uncertainty of data object attributes as well as the diversity and abstraction of data representation, a management strategy for TCM data based on big data technology is proposed. Based on true characteristics of TCM data, this strategy could solve the problems of the uncertainty of data object attributes in TCM information and the non uniformity of the data representation by using modeless properties of stored objects in big data technology. Hybrid indexing mode was also used to solve the conflicts brought by different storage modes in indexing process, with powerful capabilities in query processing of massive data through efficient parallel MapReduce process. The theoretical analysis provided the management framework and its key technology, while its performance was tested on Hadoop by using several common traditional Chinese medicines and prescriptions from practical TCM data source. Result showed that this strategy can effectively solve the storage problem of TCM information, with good performance in query efficiency, completeness and robustness.

AB - The soil fertility has great impacts on the yielding of Chinese medicinal materials, as well as the generation of major components. The practices showed that soil fertility has been decayed with the growth of cultivation years,which is leading to adverse effect on quality and quantity of Chinese medicinal materials. However, there was a lack of domestic unified standard for assessment of soil fertility of Chinese medicinal material cultivation, which has seriously limited the soil management and quality control. In this text, we reviewed the progress on research of soil fertility evaluation, built the soil fertility evaluation index including soil texture,soil bulk density,soil organic matter,soil acidity and alkalinity,soil available nitrogen,soil available phosphorus, soil available potassium,soil animals and soil microorganisms. It would provide the direction and thought for standard-settin on soil fertility evaluation of Chinese medicinal material cultivation.

AB - The coincidence of the existing eczema animal model and the clinical characteristics of eczema, and the application characteristics of eczema animal model were analyzed, and the evaluation method and improvement method of corresponding eczema animal model was put forward. Based on the clinical diagnostic criteria of eczema of traditional Chinese medicine and western medicine, the characteristics of current eczema model and the modeling method were summarized, and the anastomosis situations between the existing animal model and the eczema clinical characteristics were analyzed. At present, the back eczema models of mice have been usually used, which reflected the pathophysiological characteristics of clinical eczema to a certain degree. However, the existing animal models fail to reflect the clinical characteristics of traditional Chinese medicine.

AB - OBJECTIVE: To establish osteoblast-osteoclast cell co-culture system in a Transwell chamber, and detect cell viability of osteoblasts and osteoclasts in system. METHODS: Osteoblast MC3T3-E1 and mouse monocytes RAW264.7 were cultivated in vitro. RANKL-induced mouse RAW264.7 monocytes differentiated into mature osteoclasts, osteoblast-osteoclast cell co-culture system was established in Transwell chamber. Cell activity of osteoblasts and osteoclasts were detected by CCK-8 experimenting, Alizarin Red staining, TRAP staining. The expression of OPG, ALP, RANKL, TGF-b1 gene and RANKL protein in osteoblast MC3T3-E1 were detected by PCR, Western-Blot methods. Also, the expression of RANK, NF-kappaB in gene and protein level in osteoclast were measured through the same method respectively. RESULTS: The co-culture system of Mouse MC3T3-E1 cells and RAW264.7 cell were established in Transwell chamber. Co-culture system affected cell division activities of osteoblasts and osteoclasts. Differentiation of osteoblasts were increased, while differentiation of osteoclast division were slight decreased under microscope observation. OPG (0.65+/-0.08) and ALP (0.16+/-0.01) gene expression of co-culture system were less than single culture OPG(1.00+/-0.08) and ALP (1.01+/-0.16); TGF-b1(4.42+/-0.21) and RANKL(4.12+/-1.04) of osteoblasts in co-culture system were higher than TGF-b1(1.00+/-0.10) and RANKL(1.00+/-0.09) under single culture. However, gene expression of RANK(0.63+/-0.06) and NF kappaB(0.64+/-0.08) in co-culture system were decreased than RANK(1.00+/-0.08) and NF-kappaB(1.00+/-0.09), in single culture, and had significant differences. Similarly, protein expression of OPG(0.43+/-0.05) and NF-kappaB(0.59+/-0.05) of co-culture system were less than OPG(0.84+/-0.06) and NF-kappaB(1.13+/-0.03) of single culture. While RANKL protein expression (0.54+/-0.03)of co-culture system was more than single culture RANKL(0.31+/-0.03), and had statistically differences, which was in agreement of the trend of gene expression change. CONCLUSIONS: Co-culture system of mouse MC3T3-E1 cells and RAW264.7 cell was viable in Transwell chamber, and the activity of osteoblasts is higher than osteoclasts in co-culture system.

AB - OBJECTIVE: To explore function and related molecular mechanism of osteopractic total flavone (OTF) on tendon healing in rats. METHODS: Ten male rats aged for 8 weeks were collected and weighted from 180 to 220 g. Tendon stem cells were cultivated, the third tendon stem cells were used for experiment. OTP treated with 0, 0.1, 1, 10 ng/ml were added into tendon stem cells, and expression change of ALP, Runx2, OCN, VEGF, P-S6, P-4E/BP1 were detected after 14 days. Forty male rats aged for 8 weeks (weighted 180 to 220 g) were established extra-articular tendon-bone transplanting healing model, and divided into experimental group and control group. Experimental group were treated with OTF(100 mg.kg-1.d-1), while control group was treated by normal saline with the same volume. Tendon-bone healing degree were detected by biomechanical testing at 3 and 6 weeks after surgery, histological detection were applied to detect tendon-bone healing and number of new vessles. RESULTS: After treated by OTP, ALP staining and active index detection showed there were statistical differences among 0, 0.1, 1, 10 ng/ml group. After 14 days' cultivation, western blotting results showed mTOR downstream marker protein P-S6 protein expression were gradually increased with increase of density of OTP, expression of P-4E/BP1 was reduced, while expression of Runx2, OCN, VEGF were increased. Biological detection results showed that there was no significant difference in mechanical strength between experimental group(0.78+/-0.05) N/mm and control group (0.51+/-0.02) N/mm at 3 weeks after surgery, while mechanical strength in experimental group (1.36+/-0.09) N/mm was higher than control group (1.01+/-0.08) N/mm at 6 weeks after surgery. Histological results showed maturity of tendon-bone surface cell were higher at 3 and 6 weeks in experimental group, sharpey fiber growth more density, calcification extent of mesenchyme was high, and new bone, vessels were increased. CONCLUSIONS: OTF could promote osteogenic differentiation of tendon stem cells through mTOR signaling in vitro, and stimulate tendon-bone healing in bone tunnel and enhance connection quality between tendon and bone.

PMID- 29600684 TI - [Current advances on surgical treatment for knee articular cartilage injuries]. AB - Chondral injuries are short of self-healing ability and need to surgical repair after articular cartilage injury. Conventional treatment includes debridement and drainage under arthroscope, micro-fracture, osteochondral autograft transplantation (OATS), mosaiplasty and osteochondral allografts (OCA), autologous chondrocyte implantation (ACI). Debridement and drainage could remove pain factor, and has advantages of simple operation, wide clinical application and early clinical effect. Micro-fracture and osteochondral autograft transplantation is suitable for small area of cartilage repair, while the further effect showed that fibrous cartilage permeated by drill could decrease postoperative clinical effect. Osteochondral autograft transplantation has better advantages for reconstruction complete of wear-bearing joint. Autologous chondrocyte implantation and allogeneic cartilage transplantation are suitable for large area of cartilage defect, postoperative survival of allogeneic cartilage transplantation is effected by local rejection reaction and decrease further clinical effect. Cartilage tissue engineering technology could improve repair quality of autologous chondrocyte implantation, and make repair tissue close to transparent cartilage, but has limit to combined subchondral bone plate, reactive bone edema, bone loss and bad axis of lower limb. New technology is applied to cartilage injury, and has advantages of less trauma, simple operation, rapid recover, good clinical effect and less cost;and could be main method for treat cartilage injury with surgical repair technology. How to improve repair quality with compression resistance and abrasive resistance are expected to be solved. PMID- 29600685 TI - [Long non-coding RNA for metabolism of bone tissue]. AB - The mechanism of metabolism of bone and cartilage are one of focus of orthopedic knowledge, and its clinical and basic study plays an important role in preventing and treating osteoporosis, degeneration of bone and joint, bone tumor. At present, the mechanism of metabolism of bone and cartilage studied from protein, signal pathway to mRNA transcription factor regulation. As a new regulatory factor for non-coding proteins, long non-coding RNA(LncRNA) participates in physiological and pathological process. In recent years, a large number of researche showed that LncRNA plays an important role in metabolism of bone and cartilage, and proved LncRNA participates in development and conversion of bone metabolism. With the exposure of function chennel and target of LncRNA, the key role of LncRNA in bone metabolism were proved constantly. The paper concluded biological characteristics of LncRNA, function and target spot of LncRNA in bone and cratilage metabolism, and in further state gene regulatory mechanism of bone and cartilage metabolism, explore diagnosis and treatment, provide new thought and treatment target for bone metabolism. PMID- 29600686 TI - [Treatment progress on giant cell tumors of bone]. AB - Giant cell tumors(GCT) of bone is benign bone tumors with aggressive and osteolytic activity. As traditional treatment of GCT, removal of bone graft is disease with high local recurrence rate, and could reduce local recurrence by auxiliary means. Different surgical methods such as prosthesis replacement, wide resection and En-bloc resection could be selected for different parts of giant cell tumor of bone, based on the lesion location, size, extent of invasion, recurrence rate. For patients with special region of GCT of bone with removed incompletely and high surgical risk expected, arterial embolism could be performed. The application of bisphosphonates and denosumab are mainly used in treating recurrent, refractory, special parts, metastatic giant cell tumor of bone will bring new hope of treatment for giant cell tumor of bone, due to lower the recurrence rate. Chemotherapy is mainly used in the treatment of metastasis and malignant bone tumor. Radiotherapy for recurrent or unresectable bone giant cell tumor can control tumor progression, but there is the possibility of malignancy. While long-term follow-up studies and long-term results of applications of bisphosphonates and denosumab are lacking, new methods and development of new drugs are still be needed to treat patients with giant cell tumor of bone and also bring about more hope. PMID- 29600688 TI - Early robot-assisted gait retraining in non-ambulatory patients with stroke: a single blind randomized controlled trial. AB - BACKGROUND: Restoration of walking function is a primary concern of neurorehabilitation with respect to the aspired social and vocational reintegration. To date, the best practice for improving gait early after stroke is still object of debate. On one hand, repetitive task-specific approaches with higher intensities of walking have been observed to result in greater improvements of gait after stroke. Conversely there is some evidence that conventional gait training would be more effective for facilitating walking ability after stroke. AIM: To compare the effects of an early treatment protocol of add-on robot-assisted gait training with add-on conventional overground physiotherapy for improving locomotion in non-ambulatory adult stroke patients. DESIGN: Single-blind randomized controlled trial. SETTING: Neurorehabilitation hospital. POPULATION: Seventy-four subacute patients with first-ever ischemic stroke. METHODS: The patients were randomized into two groups. The training program consisted of forty, 2-hour sessions (including 45 minutes basic training, 45 minutes add-on training plus rest periods), five days a week, for eight consecutive weeks. Patients allocated to the add-on robot-assisted gait training were treated by means of the Lokomat. Patients allocated to the add-on conventional overground gait training aimed at improving postural control during gait, body weight transfer, stability during the stance phase, free swing phase, adequate heel contact and gait pattern. Primary outcome was the modified Emory Functional Ambulation Profile. Secondary outcomes were the Rivermead Motor Index, the Mobility Milestones and the Hochzirl Walking Aids Profile. RESULTS: No significant difference was observed between groups with regards to age (P=0.661), time from stroke onset (P=0.413) and the primary outcome (P=0.854) at baseline evaluation. As to the primary outcome, no significant differences were found between groups at the end of the study. As During the 8-week training, within group comparisons showed significant improvements of mean modified Emory Functional Ambulation Profile in both groups (P<0.001). CONCLUSIONS: Our results support the hypothesis that an early treatment protocol of robot-assisted gait retraining is not superior to add-on conventional gait training intervention for improving locomotion in non- ambulatory stroke patients. CLINICAL REHABILITATION IMPACT: This study might help to better understand the role of robot-assisted gait training in early phase stroke rehabilitation. PMID- 29600687 TI - Psychometric properties of the Cumulated Ambulation Score: a systematic review. AB - INTRODUCTION: In the geriatric population, independent mobility is a key factor in determining readiness for discharge following acute hospitalization. The Cumulated Ambulation Score (CAS) is a potentially valuable score that allows day to-day measurements of basic mobility. The CAS was developed and validated in older patients with hip fracture as an early postoperative predictor of short term outcome, but it is also used to assess geriatric in-patients with acute medical illness. Despite the fast-accumulating literature on the CAS, to date no systematic review synthesizing its psychometric properties has been published. Therefore, we aimed to provide a comprehensive review of the psychometric properties of the CAS, summarizing the present evidence on this measure as a basis for further research to investigate its applicability across a wider range of functional abilities and care settings. EVIDENCE ACQUISITION: A literature search was conducted on research articles published between 2006 and June 2016 in journals indexed by MEDLINE and Scopus databases using as a search item "Cumulated Ambulation Score"[All Fields], and selecting studies that presented a psychometric analysis of the scale. Of 49 studies identified, 17 examined the psychometric properties of the CAS. EVIDENCE SYNTHESIS: Most papers dealt with patients after hip fracture surgery, and only 4 studies assessed the CAS psychometric characteristics also in geriatric in-patients with acute medical illness. Two versions of CAS (CAS1 and the more detailed CAS2 version) and two different methods to calculate the total score (1-day and 3-day CAS) were used in the selected papers. Most of the papers assessed reliability and validity, using different statistics, and only one showed evidence of sensitivity to change of the score. CONCLUSIONS: This systematic review shows international interest of researchers in the CAS, despite the short time frame since its first publication in 2006. The results support the reliability, validity, and sensitivity to change of the tool. Since different versions of CAS are available and two scores are commonly used, we suggest that clinicians and researchers in the future choose the more detailed CAS2 version, already used by the large majority of studies, and report whether they used the 1- or 3-day score.

AB - BACKGROUND: In Italy, the incidence of human tick borne disease has increased over the last decades. Since 2015 a multidisciplinary group has been established in Sacco Hospital for the management of the patients affected by Lyme Disease (LD). A retrospective evaluation (2015-2017) was performed for LD in non-endemic areas. METHODS: Retrospective analysis of all 1000 samples for 800 patients screened for LD antibodies at the Sacco Hospital in 3 years (2015-2017). Revision of clinical et epidemiological patients data available and correlation with the serological results. RESULTS: Among the 800 patients screened only 134 of them were diagnosed with borreliosis: 37 cases during 2015, 31 during 2016 and 66 during 2017. Localized Lyme disease was diagnosed of 134 cases (69%): in most of them (N=63) erythema migrans (EM) has been documented; in 37 out of 100 it was not possible to detect it. In only three cases, patients complained of different clinicali symptoms such as headache, arm and facial pain respectively. 23 out of 144 cases (16%) showed a persistence of serological positivity and symptoms with osteomuscular involvement and fatigue, despite the therapy (Late Lyme disease). In that same study 11 out of 144 patients (7%) received a diagnosis of neuroborreliosis. CONCLUSIONS: Our data reported an high percentage of Lyme Disease infection (19%) in non endemic area. The definition of a multidisciplinary working group and a clinical care pathway allowed a better clinical management of Lyme disease cases treated in Sacco Hospital, Milan.

PMID- 29600692 TI - The window of opportunities for targeted therapy in BRAFwt/NRASwt/KITwt melanoma: biology and clinical implications of fusion proteins and other mutations. AB - Treatment options in advanced melanoma have been subject to a major change over the last years. The discovery of the oncogenic point mutation BRAFV600E and subsequently developed BRAF inhibitors had a major impact on patient's survival. Further important mutations have been found in the NRAS gene, although not yet druggable, and others involve c-kit in acral and mucosal melanoma. Imatinib was shown to achieve high response rates in c-kit mutated melanoma. Despite good response rates in these targeted therapies and introduction of immunotherapy, there are still patients left, who develop resistance upon therapy or patients without the option of targeted therapy. Therefore it is necessary to identify further therapeutic options for this subset of patients. Several new mutations have been described so far that might be suitable for targeted therapy or useful as clinical biomarkers. Alterations in various receptor tyrosine kinases lead to constitutively activated downstream signaling and might be responsible for non response to common therapies. In contrast, tyrosine kinase inhibitors such as sunitinib or nilotinib could be suitable for patients harboring those alterations. Additionally, chromosomal rearrangements have been described in many different cancer types, resulting in oncogenic fusion proteins that involve BRAF, ROS1, NTRK, ALK and others. These are an emerging therapeutic field, especially in spitzoid melanomas. Further mutations have been detected in the neurofibromin 1 and RAC1 gene, although the clinical relevance is still not fully revealed. Within this review we will summarize the current evidence and focus on possible further upcoming targets and therapeutic opportunities in BRAFwt/NRASwt/KITwt melanoma. PMID- 29600693 TI - Photodynamic therapy for aesthetic-cosmetic indications. AB - Photodynamic therapy (PDT) is a well-established, non-invasive treatment for a variety of dermatologic disorders, including actinic keratosis. Furthermore, PDT results in marked improvements in the signs of skin aging, although currently there are no standardized guidelines for PDT in skin rejuvenation. Two types of PDT are available: conventional-PDT (c-PDT) and the newly introduced daylight-PDT (DL-PDT). Both require a topical photosensitizer, a light source and oxygen, and both are comparable regarding safety and efficacy for treatment of photo-induced skin aging. Treatment is particularly effective for improvement of fine wrinkles, skin roughness, actinic elastosis and mottled hyperpigmentation. The most widely studied topical sensitizers used in PDT are 5-aminolevulinic acid (ALA) and methyl aminolevulinate (MAL). A range of pre-treatment procedures help improve skin absorption of the photosensitizer and lead to significantly improved efficacy. A variety of activating light sources can be used for c-PDT, while DL PDT uses natural daylight, making it easier to treat larger areas of photodamaged skin. A major limitation of c-PDT is significant treatment-related pain, but DL PDT has proved to be an almost pain-free procedure. Treatment duration is based on individual patient need but most patients receive 2 to 3 treatment cycles, with results fully evident 3-6 months post-treatment. PDT for aesthetic-cosmetic treatments has established its value in modern procedural dermatology as mono- or combination therapy. A major, unique advantage of PDT is that it is a non invasive treatment that effectively rejuvenates photodamaged skin, while successfully treating a range of dermatologic conditions, including prevention and therapy of pre-cancerous actinic keratosis.

AB - Helicobacter pylori is one of the most common gastrointestinal infection affecting humans worldwide. Hp colonizes the stomach with preferential trophism for the antrum. Hp infection is associated with the development of a chronic gastritis and subsequently with several gastric diseases such as peptic disease, gastric carcinoma and MALT lymphoma. Moreover, Helicobacter pylori infection has also been reported in literature to be associated with many other extra-gastric conditions including sideropenic anemia, thrombocytopenia, neurological, liver and cardiovascular diseases. For some conditions the association is supported by solid literature data and also by the identification of the possible physiopathogenetic mechanism involved. In other cases, the link is only reported by association studies often with conflicting results. In this context, diabetes mellitus, cardiovascular disorders and liver steatosis have all been reported to be associated with Helicobacter pylori infection. Interestingly, these conditions share many characteristics and they often overlap as they represent the expression of the so called metabolic syndrome. Aim of the review was to summarize the available data regarding the association between Helicobacter Pylori infection and diabetes mellitus, cardiovascular disorders and liver steatosis. PMID- 29600697 TI - Pharmacological considerations and step-by-step proposal for the treatment of Helicobacter pylori infection in the year 2018. AB - Over the past 30 years, multidrug regimens consisting of a proton pump inhibitor (PPI) and two or three antibiotics have been used in treating Helicobacter pylori (H. pylori) infection. In clinical practice, the optimal regimen to cure H. pylori infection should be decided regionally. Considering the first treatment, the Maastricht V/Florence Consensus Report and the American College of Gastroenterology Clinical Management Guideline highlight that in countries with low clarithromycin resistance rates (<15%), an empiric clarithromycin-based regimen can be used. In countries with high clarithromycin resistance rates or, in the American Guideline, with a previous exposure to clarithromycin, a bismuth containing quadruple therapy (with metronidazole and tetracycline) is the first choice. In case of persistent infection, after a previous clarithromycin containing regimen, this drug should be avoided in second line therapy. Options after initial eradication failure include tailored therapy (choosing antibiotic combinations based on antibiotic susceptibility testing), empiric bismuth containing quadruple therapy or triple levofloxacin-based therapy. Encouraging data are reported, both for the first-line and for rescue treatments, with the use of a formulation of bismuth subcitrate potassium, metronidazole, and tetracycline contained in a single capsule, together with a PPI. Rifabutin- and furazolidone-based regimens should also be considered in rescue regimens. Vonoprazan, a new type of potassium-competitive acid blocker that produces more potent acid inhibition than PPIs, provides improved H. pylori eradication rates in combination with antibiotics. In this review, the authors provide an overview on the current knowledge on the treatment of H. pylori infection, with focus on therapeutic challenges in this field. PMID- 29600698 TI - The role of microbiota in autism spectrum disorders. AB - Autism spectrum disorder (ASD) defines a set of neurodevelopmental disorders characterized by persistent deficits in social communication and interaction, along with repetitive patterns of behavior. Symptoms generally appear in the early developmental period and cause significant impairment in individual and social functioning. In recent years the increased prevalence of ASD, along with the evidence of a significant link between autism and gastrointestinal (GI) disturbances, raised a special interest in exploring the reciprocal influences between gut and brain. Investigators highlighted the existence of a so-called "gut-brain axis," empowering the hypothesis that GI abnormalities could trigger neuropsychiatric symptoms in ASD. Intestinal microbiota is thought to play a pivotal role in gut and systemic homeostasis, in central nervous system development, as well as in behavioral modulation and recurrent microbial imbalances have been shown in gut microbiota of autistic people. In this review we analyze current knowledge about intestinal microbiota and the relevance and role of dysbiosis in ASD. The most accredited theories about gut-brain interaction will be reviewed, along with current scientific evidence supporting the relationship between microbial imbalances and impairment of neurodevelopment. Finally, we will focus on the results of different therapeutic approaches in this context: administration of pre- and probiotics, antibiotics, fecal microbiota transplantation and special diets and dietary supplements. PMID- 29600699 TI - Cyanopyrimidine-Carbazole Hybrid Host Materials for High-Efficiency and Low Efficiency Roll-Off TADF OLEDs. AB - Two isomeric host materials (Sy and Asy) comprising carbazole (donor) and CN substituted pyrimidine (acceptor) were synthesized, characterized, and utilized as host materials for green and blue thermally activated delayed fluorescence (TADF) organic light emitting diodes (OLEDs). Both molecules have high triplet energy and small energy difference between singlet and triplet states, leading to feasible TADF. The different linking topologies of carbazole and CN groups on the pyrimidine core provide distinct photophysical properties and molecular packing manners, which further influence the efficiency as they served as hosts in TADF OLEDs. As compared to Asy-based cases, the Sy-hosted TADF OLED device gave higher maximum external quantum efficiencies (EQE) of 24.0% (vs 22.5%) for green (4CzIPN as a dopant) and 20.4% (vs 15.0%) for blue (2CzTPN as a dopant) and low efficiency roll-off. The high horizontal dipole ratio (Theta ~ 88%) for both emitters dispersed in Sy and Asy hosts accounts for the high device efficiency. A clear molecular structure-physical property-device performance relationship has been established to highlight the importance of symmetrical structure in TADF host material design. PMID- 29600700 TI - Separation of Branched Poly(bisphenol A carbonate) Structures by Solvent Gradient at Near-Critical Conditions and Two-Dimensional Liquid Chromatography. AB - Branching is a molecular metric that strongly influences the application properties of polymers. Consequently, detailed information on the microstructure is required to gain a deeper understanding of structure-property relationships. In the present case, we employ high-performance liquid chromatography to characterize the branching in a poly(bisphenol A carbonate) (PC). To this end, a method was developed based on a mobile phase gradient in a very narrow range (+/ 1.4 vol %) around the point of adsorption (98.9/1.1 vol % chloroform/methyl tert butyl ether), which we refer to as solvent gradient at near-critical conditions. Application of such gentle gradient enabled separation of PC according to end groups. The separation mechanism was confirmed by collecting fractions of a separated sample and subsequently analyzing these by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Hyphenating the developed gradient method with size-exclusion chromatography as the second dimension (2D LC) enabled separation of linear and branched PC chains and determination of the molar mass distribution of the fractions. A reversed elution order was observed for branched species in 2D-LC, meaning that low molar mass chains exhibited higher elution volumes in the first dimension than higher molar masses. This finding was explained by influences of end-groups as well as the architecture of the branched polymer chains. PMID- 29600701 TI - Flexible Multifunctional Aromatic Polyimide Film: Highly Efficient Photoluminescence, Resistive Switching Characteristic, and Electroluminescence. AB - We report a flexible multifunctional aromatic polyimide (BTDBPI) that shows yellow-green fluorescence with high photoluminescence quantum yield (PLQY) of 30% in the film state. The nonvolatile "write once-read many" (WORM) characteristic in a memory device with the configuration of ITO/BTDBPI/Au indicates that BTDBPI possesses organic semiconductor behavior. Moreover, polymer light-emitting diodes (PLEDs) with the structure of ITO/PEDOT:PSS/BTDBPI/TPBI/Mg-Ag exhibits an interesting dual-emission phenomenon that originates from the electroluminescence (EL) of the BTDBPI nanometer film (yellow-green, 525 nm) and TPBI (deep blue, 380 nm), demonstrating that BTDBPI shows both the charge-transporting and EL properties. PMID- 29600702 TI - Bronsted-Acid-Promoted Rh-Catalyzed Asymmetric Hydrogenation of N-Unprotected Indoles: A Cocatalysis of Transition Metal and Anion Binding. AB - The incorporation of Bronsted acid, thiourea anion binding, and transition metal catalysis enables an efficient method to synthesize chiral indolines via hydrogenation of indoles. Catalyzed by a rhodium/ZhaoPhos complex, asymmetric hydrogenation of unprotected indoles is performed smoothly with excellent enantioselectivities (up to 99% ee, up to 400 TON). Bronsted acid HCl activates indoles to form iminium ion intermediates. Mechanistic studies support the assumption that anion binding plays a crucial role as a secondary interaction. DFT calculations reveal an outer-sphere mechanism in this chemical transformation. PMID- 29600703 TI - BODIPY-Based Two-Photon Fluorescent Probe for Real-Time Monitoring of Lysosomal Viscosity with Fluorescence Lifetime Imaging Microscopy. AB - The viscosity of lysosome is reported to be a key indicator of lysosomal functionality. However, the existing mechanical methods of viscosity measurement can hardly be applied at the cellular or subcellular level. Herein, a BODIPY based two-photon fluorescent probe was presented for monitoring lysosomal viscosity with high spatial and temporal resolution. By installing two morpholine moieties to the fluorophore as target and rotational groups, the TICT effect between the two morpholine rings and the main fluorophore scaffold endowed the probe with excellent viscosity sensitivity. Moreover, Lyso-B succeeded in showing the impact of dexamethasone on lysosomal viscosity in real time. PMID- 29600704 TI - Formation of Strong Basicity on Covalent Triazine Frameworks as Catalysts for the Oxidation of Methylene Compounds. AB - Porous solid bases are increasingly attractive for applications in green chemistry and heterogeneous catalysis under relatively mild conditions. Here, covalent triazine frameworks (CTFs) were first applied as a support for the porous solid strong bases through a redox process between the base precursor KNO3 and CTFs, leading to a relatively low calcination temperature (400 degrees C). As a result, porous organic frameworks possessing ordered microstructures as well as strong basic sites were successfully synthesized. The materials were characterized by X-ray diffraction, Fourier transform infrared, high-resolution transmission electron microscopy, temperature programmed desorption of CO2, and so forth. The obtained solid bases displayed remarkable catalytic activity in the aerobic oxidation of methylene compounds, and the yield of fluorenones could reach 93.6% at 120 degrees C, which was nearly 3 times higher than that of the control catalyst. The current research may present a new idea for the construction of porous organic polymers with strong basicity. PMID- 29600705 TI - Transforming Monolayer Transition-Metal Dichalcogenide Nanosheets into One Dimensional Nanoscrolls with High Photosensitivity. AB - One-dimensional (1D) nanoscrolls derived from two-dimensional (2D) nanosheets own unusual physical and chemical properties that arise from the spiraled 1D morphology and the atomic thin 2D building blocks. Unfortunately, preparation of large-sized nanoscrolls of transition-metal dichalcogenides (TMDCs) remains a big challenge, which greatly restricts the fabrication of single-scroll devices for their fundamental studies and further applications. In this work, we report a universal and facile method, by making use of the evaporation process of volatile organic solvent, to prepare TMDC (e.g., MoS2 and WS2) nanoscrolls with lengths of several tens to one hundred micrometers from their 2D precursors presynthesized by chemical vapor deposition on Si/SiO2. Both atomic force microscopy and electron microscopy characterizations confirmed the spirally rolledup structure in the resulting nanoscrolls. An interlayer spacing of as small as ~0.65 nm was observed, suggesting the strong coupling between adjacent layers, which was further evidenced by the emergence of new breathing mode peaks in the ultralow frequency Raman spectrum. Importantly, compared with the photodetector fabricated from a monolayer MoS2 or WS2 nanosheet, the device based on an MoS2 or WS2 nanoscroll showed the much enhanced performance, respectively, with the photosensitivity greatly increased up to 2 orders of magnitude. Our work suggests that turning 2D TMDCs into 1D scrolls is promising in achieving high performances in various electronic/optoelectronic applications, and our general method can be extended to the preparation of large-sized nanoscrolls of other kinds of 2D materials that may bring about new properties and phenomena. PMID- 29600706 TI - Accelerating the Pace of Chemical Risk Assessment. AB - Changes in chemical regulations worldwide have increased the demand for new data on chemical safety. New approach methodologies (NAMs) are defined broadly here as including in silico approaches and in chemico and in vitro assays, as well as the inclusion of information from the exposure of chemicals in the context of hazard [European Chemicals Agency, " New Approach Methodologies in Regulatory Science ", 2016]. NAMs for toxicity testing, including alternatives to animal testing approaches, have shown promise to provide a large amount of data to fill information gaps in both hazard and exposure. In order to increase experience with the new data and to advance the applications of NAM data to evaluate the safety of data-poor chemicals, demonstration case studies have to be developed to build confidence in their usability. Case studies can be used to explore the domains of applicability of the NAM data and identify areas that would benefit from further research, development, and application. To ensure that this science evolves with direct input from and engagement by risk managers and regulatory decision makers, a workshop was convened among senior leaders from international regulatory agencies to identify common barriers for using NAMs and to propose next steps to address them. Central to the workshop were a series of collaborative case studies designed to explore areas where the benefits of NAM data could be demonstrated. These included use of in vitro bioassays data in combination with exposure estimates to derive a quantitative assessment of risk, use of NAMs for updating chemical categorizations, and use of NAMs to increase understanding of exposure and human health toxicity of various chemicals. The case study approach proved effective in building collaborations and engagement with regulatory decision makers and to promote the importance of data and knowledge sharing among international regulatory agencies. The case studies will be continued to explore new ways of describing hazard (i.e., pathway perturbations as a measure of adversity) and new ways of describing risk (i.e., using NAMs to identify protective levels without necessarily being predictive of a specific hazard). Importantly, the case studies also highlighted the need for increased training and communication across the various communities including the risk assessors, regulators, stakeholders (e.g., industry, non-governmental organizations), and the general public. The development and application of NAMs will play an increasing role in filling important data gaps on the safety of chemicals, but confidence in NAMs will only come with learning by doing and sharing in the experience. PMID- 29600707 TI - Characteristics of Polybrominated Diphenyl Ethers Released from Thermal Treatment and Open Burning of E-Waste. AB - Primitive processing of e-waste potentially releases abundant organic contaminants to the environment, but the magnitudes and mechanisms remain to be adequately addressed. We conducted thermal treatment and open burning of typical e-wastes, that is, plastics and printed circuit boards. Emission factors of the sum of 39 polybrominated diphenyl ethers (?39PBDE) were 817-1.60 * 105 ng g-1 in thermal treatment and nondetected-9.14 * 104 ng g-1, in open burning. Airborne particles (87%) were the main carriers of PBDEs, followed by residual ashes (13%) and gaseous constituents (0.3%), in thermal treatment, while they were 30%, 43% and 27% in open burning. The output-input mass ratios of ?39PBDE were 0.12-3.76 in thermal treatment and 0-0.16 in open burning. All PBDEs were largely affiliated with fine particles, with geometric mean diameters at 0.61-0.83 MUm in thermal degradation and 0.57-1.16 MUm in open burning from plastic casings, and 0.44-0.56 and nondetected- 0.55 MUm, from printed circuit boards. Evaporation and reabsorption may be the main emission mechanisms for lightly brominated BDEs, but heavily brominated BDEs tend to affiliate with particles from heating or combustion. The different size distributions of particulate PBDEs in emission sources and adjacent air implicated a noteworthy redisposition process during atmospheric dispersal.

AB - An umpolung reaction of the alpha-imino thioester was examined, and we found that alpha-imino thioesters were more effective substrates for the umpolung N alkylation than conventional alpha-imino esters and they gave N-alkylated amino thioesters in high yields under mild reaction conditions in a short time. A new type of C-C bond formation followed by an unexpected rearrangement of the alkylthio group took place with the unsaturated ketones to afford the beta alkylthio-alpha-amino thioesters in high yields with good diastereoselectivity.

The reactions proceeded smoothly to afford the pyrrole derivatives in good to high yields. A wide range of Michael acceptors, such as alpha,beta-unsaturated carbonyl compounds and nitroolefin, were successfully applied to this reaction.

The transformation proceeds smoothly in the presence of K2CO3 as a base and KI as an additive. An excellent reaction scope is observed. A 2 mmol scaled synthesis of alpha methylene-beta-lactams and synthetic applications of alpha-methylene-beta-lactams are also reached. In the process, it is believed that an intramolecular 1,2 addition of N-propiolamide and sequential C-C bond migrating cleavage are involved. PMID- 29600711 TI - JQ-1 Inhibits Colon Cancer Proliferation via Suppressing Wnt/beta-Catenin Signaling and miR-21. AB - Bromodoamin and extraterminal (BET) protein inhibitors are a novel class of cancer therapeutics. Here we aim to investigate the efficacy and mechanism of JQ 1, a potent BET inhibitor, in colon cancer therapy. JQ-1 was used to treat SW480 colon cancer mouse xenografts. The tumor size and mouse survival were recorded. Cell apoptosis was evaluated by Annex V-FIC/PI flow cytometry. ChIP-q-PCR analysis was used to assess the H3K27 trimethylation (H3K27m3) of the p16 promoter. Wnt signaling was evaluated by Nkd2 and beta-catenin levels. RT-PCR was used to evaluate the level of miR-21. MiR-21 was overexpressed with a lentiviral system and was used to evaluate the relationship between miR-21 and JQ-1. JQ-1 significantly reduced tumor growth, improved mouse survival, and induced apoptosis. JQ-1 epigenetically inhibited the H3K27me3 promoter activity, promoting p16 expression. Nkd2 and beta-catenin were upregulated and downregulated by JQ-1, respectively. MiR-21 was downregulated by JQ-1. MiR-21 overexpression compensated for proliferation inhibition by JQ-1. Nkd2 levels were also downregulated by miR-21 overexpression. JQ-1 is effective in inhibiting colon cancer.

AB - Calcium release-activated calcium (CRAC) channels open upon depletion of Ca2+ from the endoplasmic reticulum, and when open, they are permeable to a selective flux of calcium ions. The atomic structure of Orai, the pore domain of CRAC channels, from Drosophila melanogaster has revealed many details about conduction and selectivity in this family of ion channels. However, it is still unclear how residues on the third transmembrane helix can affect the conduction properties of the channel. Here, molecular dynamics and Brownian dynamics simulations were employed to analyze how a conserved glutamate residue on the third transmembrane helix (E262) contributes to selectivity. The comparison between the wild-type and mutated channels revealed a severe impact of the mutation on the hydration pattern of the pore domain and on the dynamics of residues K270, and Brownian dynamics simulations proved that the altered configuration of residues K270 in the mutated channel impairs selectivity to Ca2+ over Na+. The crevices of water molecules, revealed by molecular dynamics simulations, are perfectly located to contribute to the dynamics of the hydrophobic gate and the basic gate, suggesting a possible role in channel opening and in selectivity function.

AB - beta-Graphdiyne (beta-GDY) is a two-dimensional carbon material with zero band gap and highly intrinsic carrier mobility and a promising material with potential applications in electronic devices. However, the synthesis of continuous single or ultrathin beta-GDY has not been realized yet. Here, we proposed an approach for ultrathin beta-GDY-like film synthesis using graphene as a template because of the strong pi-pi interaction between beta-GDY and graphene. The as-synthesized film presents smooth and continuous morphology and has good crystallinity. Electrical measurement reveals that the film presented a conductivity of 1.30 * 10-2 S.m-1 by fabricating electronic devices on beta-GDY grown on a dielectric hexagonal boron nitride template.

AB - The elemental profile of the leaf samples of three Cabernet Franc clone candidates recently developed in Serbia (Nos. 02, 010 and 012) obtained in the last phase of clonal selection was examined within this study by ICP-OES. Optimal content of Al, Fe, Cu and Zn, the metals well known for their links with a number of neurodegenerative disorders including Alzheimer's disease, has actually highlighted the potential of the leaf sample No. 10 to afford a novel food supplement of natural origin possessing well balanced metal ingredients. Furthermore, lower content of some other elements (Cr, Mn, Ni and Pb) thoroughly supports such a claiming. Finally, the most favourable K/Na ratio observed for the aforementioned sample points out its likely cardioprotectivity. However, two other Cabernet Franc clone candidates might also be recommended for breeding in the same or similar viticultural conditions, since all obtained values were below toxic ones for human consumption.

AB - A new polyene compound (1) and a new diketopiperazine (2), as well as three known compounds (3-5), were isolated from the Antarctic marine-derived fungus Penicillium crustosum HDN153086. The structures of 1-5 were deduced based on MS, NMR and TD-DFT calculations of specific ECD spectra. These compounds were evaluated for their cytotoxic activities against K562 cell line and only compound 2 exhibited cytotoxicity against K562 cell, with IC50 value of 12.7 MUM. PMID- 29600718 TI - Synthesis, characterization, and biological evaluations of some steryl 2 methoxybenzoates as anticancer agents. AB - Using cholesterol, stigmasterol and sitosterol as starting materials, a series of 7-subsitituted-ster-3-yl 2-methoxybenzoate analogs were prepared through reacting with 2-methoxybenzoyl chloride and introducing some function groups, such as carbonyl, hydroxyl and various thiosemicarbazones, at 7-position of steroidal nucleus. The structures of these new compounds were characterized by IR, NMR and HRMS. Their antiproliferative activities were evaluated by using several types of cancer cells. Interestingly, the compounds displayed potent antiproliferative activity against CNE-2 (nasopharyngeal carcinoma cell lines), BEL-7402 (human liver cancer cell lines) and HepG2 (human liver cancer cell lines), suggesting that they have potential to be drug candidates for cancer treatment. PMID- 29600719 TI - Comparison of Plantar Fasciitis Injected With Platelet-Rich Plasma vs Corticosteroids. AB - BACKGROUND: Plantar fasciitis is one of the most common causes of heel pain. This prospective study compared the efficacy of local injection of corticosteroids vs platelet-rich plasma (PRP) in the treatment of plantar fasciitis. METHODS: Patients were randomly allocated into 2 groups of 40 each (group A and group B). Patients were treated with local corticosteroid injection in group A and autologous PRP injection in group B. Clinical assessment was done prior to the injection and at 1 month, 3 months, and 6 months following the injection, which included visual analog pain scale, subjective rating using the modified Roles and Maudsley score, functional outcome score by the Foot and Ankle Outcome Instrument (FAI) core scale, and the American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale. Radiological assessment was done by measuring the thickness of the plantar fascia using ultrasonography. The mean age, sex, and body mass index of both groups were comparable. RESULTS: Postinjection, there was significant improvement of visual analog score, modified Roles and Maudsley score, FAI core scale, AOFAS ankle-hindfoot score, and plantar fascia thickness in both the groups. However, with the numbers available, no significant difference in improvement could be detected between the above-mentioned variables in the 2 groups. CONCLUSION: We found that the treatment of plantar fasciitis with steroid or PRP injection was equally effective. LEVEL OF EVIDENCE: Level II, prospective randomized comparative series. PMID- 29600720 TI - Effect of Ankle Position on Tibiotalar Motion With Screw Fixation of the Distal Tibiofibular Syndesmosis in a Fracture Model. AB - BACKGROUND: Anatomic reduction and fixation of the syndesmosis in traumatic injuries is paramount in restoring function of the tibiotalar joint. While overcompression is a potential error, recent work has called into question whether ankle position during fixation really matters in this regard. Our study aimed to corroborate more recent findings using a fracture model that, to our knowledge, has not been previously tested. METHODS: Twenty cadaver leg specimens were obtained and prepared. Each was tested for tibiotalar motion under various conditions: intact syndesmosis, intact syndesmosis with lag screw compression, pronation external rotation type 4 (PER-4) ankle fracture with syndesmotic disruption, and single-screw syndesmotic fixation followed by plate and screw fracture and syndesmotic screw fixation. In each situation, the ankle was held in alternating plantarflexion and dorsiflexion when inserting the syndesmotic screw with the subsequent amount of maximal dorsiflexion being recorded following hand tight lag screw fixation. RESULTS: While ankle range of motion increased significantly with creation of the PER-4 injury, under no condition was there a statistically significant change in maximal dorsiflexion angle. CONCLUSION: Ankle position during distal tibiofibular syndesmosis fixation did not limit dorsiflexion of the ankle joint. CLINICAL RELEVANCE: Our findings suggest that maximal dorsiflexion during syndesmotic screw fixation may not be necessary. PMID- 29600721 TI - Optimized protocol for multigram preparation of emodin anthrone, a precursor in the hypericin synthesis. AB - Emodin reduction to emodin anthrone comprise one of three process steps involved in the hypericin synthesis, a powerful natural photosensitiser found in plants of the genus Hypericum. In this communication, an optimized protocol was established for emodin reduction enabling an efficient multigram preparation of emodin anthrone. A screening of reducing agent (SnCl2.2H2O and HClconc) under different reaction times was employed in micro-scale and monitored by electronic absorption spectroscopy technique. Data showed lower yields of emodin anthrone when some experimental conditions previously described in the literature were reproduce. However, using the optimized protocol for the emodin reduction these yields were overcoming, and a gram-scale supply experiment was reproducible for the preparation of 10 grams of emodin anthrone with excellent yield.

AB - Early Science and Technology Studies (STS) scholars recognized that the social construction of knowledge depends on skepticism's parasitic relationship to background expectations and trust. Subsequent generations have paid less empirical attention to skepticism in science and its relationship with trust. I seek to rehabilitate skepticism in STS - particularly, Merton's view of skepticism as a scientific norm sustained by trust among status peers - with a study of what I call 'civil skepticism'. The empirical grounding is a case in contemporary dendroclimatology and the development of a method ('Blue Intensity') for generating knowledge about climate change from trees. I present a sequence of four instances of civil skepticism involved in making Blue Intensity more resistant to critique, and hence credible (in laboratory experiments, workshops, conferences, and peer-review of articles). These skeptical interactions depended upon maintaining communal notions of civility among an increasingly extended network of mutually trusted peers through a variety of means: by making Blue Intensity complementary to existing methods used to study a diverse natural world (tree-ring patterns) and by contributing to a shared professional goal (the study of global climate change). I conclude with a sociological theory about the role of civil skepticism in constituting knowledge-claims of greater generality and relevance. PMID- 29600724 TI - Localization of Intracranial Lesions Using Superficial Stereotaxic Cranial Lesion Locator Based on Magnetic Resonance Images. AB - BACKGROUND: Detection of a deep-seated lesion located in the brain parenchyma and major neuroanatomical sites is a critical issue in neurosurgery. Some neurosurgical cranial navigation systems have been developed that are available; however, some preparation is necessary, including the installation of complex computer software programs and obtaining specific neuroradiological images. OBJECTIVE: The purpose of this experimental study was to design and evaluate a superficial stereotaxic frameless lesion locator in order to localize mass lesions within the brain. METHODS: A superficial stereotaxic frameless lesion locator system was designed using cardboard and the Cartesian coordinate system as a reference framework. This material was used in a model creating printed magnetic resonance images in the superficially marking of the lesion. This material easily located the lesion placement and superficially projected the lesion location. RESULTS: The results of this study revealed that the superficial stereotaxic frameless lesion location procedure using a coordinate cardboard locator is a safe, fast, and simple procedure. This procedure provides an accurate means of locating the target lesion seated within the brain parenchyma. When compared with other models, we found that this device is reliable and has a high rate of superficial lesion detection. CONCLUSION: A superficial lesion locator may be used in clinical practice. This experimental study demonstrated the usability and reliability of the procedure. Additional detailed investigations are necessary to improve the procedure. PMID- 29600725 TI - Overview of Impella and mechanical devices in cardiogenic shock. AB - INTRODUCTION: Cardiogenic shock (CS) is a life-threatening condition associated with significant morbidity and mortality. The Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta. It is used for high-risk percutaneous coronary intervention and CS. Areas covered: Percutaneous mechanical support devices are placed in a minimally invasive manner and provide life-saving assistance. We review Impella and other percutaneous devices such as intra-aortic balloon pump, TandemHeart, and extracorporeal membrane oxygenation (ECMO) and the evidence supporting their use in the setting of CS. Expert commentary: Impella has been proven to be safe and may be superior to other mechanical support devices in CS. PMID- 29600726 TI - Aerobic With Resistance Training or Aerobic Training Alone Poststroke: A Secondary Analysis From a Randomized Clinical Trial. AB - BACKGROUND: Stroke is associated with muscle atrophy and weakness, mobility deficits, and cardiorespiratory deconditioning. Aerobic and resistance training (AT and RT) each have the potential to improve deficits, yet there is limited evidence on the utility of combined training. OBJECTIVE: To examine the effects of AT+RT versus AT on physiological outcomes in chronic stroke with motor impairments. METHODS: Participants (n = 73) were randomized to 6 months of AT (5 d/wk) or AT+RT (3 and 2 d/wk, respectively). Outcomes included those related to body composition by dual-energy X-ray absorptiometry, mobility (6-minute walk distance [6MWD], sit-to-stand, and stair climb performance), cardiorespiratory fitness (VO2peak, oxygen uptake at the ventilatory threshold [VO2VT]), and muscular strength. RESULTS: A total of 68 (93.2%) participants (age, mean +/- SD = 63.7 +/- 11.9) completed the study. AT+RT and AT yielded similar and significant improvements in 6MWD (39.9 +/- 55.6 vs 36.5 +/- 63.7 m, P = .8), VO2peak (16.4% +/- 43.8% vs 15.2% +/- 24.7%, P = .9), sit-to-stand time (-2.3 +/- 5.1 vs 1.02 +/- 9.5 s, P = .05), and stair climb performance (8.2% +/- 19.6% vs 7.5% +/- 23%, P = .97), respectively. AT+RT produced greater improvements than AT alone for total body lean mass (1.23 +/- 2.3 vs 0.27 +/- 1.6 kg, P = .039), predominantly trunk ( P = .02) and affected-side limbs ( P = .04), VO2VT (19.1% +/- 26.8% vs 10.5% +/- 28.9%, P = .046), and upper- and lower-limb muscular strength ( P < .03, all except affected-side leg). CONCLUSION: Despite being prescribed 40% less AT, AT+RT resulted in similar and significant improvement in mobility and VO2peak, superior improvements in VO2VT and muscular strength, and an almost 5-fold greater increase in lean mass compared with AT. RT is the most neglected exercise component following stroke but should be prescribed with AT for metabolic, cardiorespiratory, and strength recovery. PMID- 29600727 TI - Clinical and neonatal outcomes of intrauterine insemination with frozen donor sperm. AB - : This retrospective study evaluated the association between frozen donor sperm used for intrauterine insemination and clinical and neonatal outcomes, including 304 singleton pregnancies resulting from artificial insemination by the husband (AIH) and 173 singleton pregnancies resulting from artificial insemination by a donor (AID). The clinical outcomes for AID showed no increased risk of abortion, ectopic pregnancy or pregnancy complications compared to those for AIH. There were no differences in gender, gestational age or prematurity of live births between the two groups. However, the birthweight of live births from AID was significantly higher than that from AIH. Moreover, the AID group exhibited no increased risk of stillbirths or fetal defects compared to the AIH group. These results indicate that frozen donor sperm did not increase the occurrence of adverse clinical and neonatal outcomes when compared to sperm from the husband. ABBREVIATIONS: AID: artificial insemination by a donor; AIH: artificial insemination by the husband; ART: assisted reproduction technology; FET: frozen embryo transfer; IVF: in vitro fertilization; ICSI: intracytoplasmic sperm injection; IUI: intrauterine insemination; LBW: low birth weight. PMID- 29600728 TI - Cardiotrophin-1 as a new metabolic biomarker in women with PCOS. AB - The objective of this study was to investigate cardiotrophin-1 (CT-1) levels as a new metabolic biomarker in women with polycystic ovary syndrome (PCOS). One hundred consecutive women with PCOS were divided into two groups according to presence of metabolic syndrome as MetS+ and MetS-. Clinical, hormonal and metabolic parameters in addition to CT-1 levels were compared between the groups. Correlation analyses were performed between CT-1 and clinical and metabolic parameters in women with PCOS. One hundred PCOS subjects were enrolled in the study, of which 29 subjects were diagnosed with metabolic syndrome. WHR, systolic and diastolic blood pressures, triglyceride, total cholesterol, HOMA-IR, FAI, FGS and CT-1 levels were significantly higher in the MetS+ group compared with the MetS- group. HDL cholesterol was significantly higher in the MetS- group than the MetS+ one. CT-1 levels were found to be positively correlated with diastolic blood pressure, TG levels and FGS. Cardiotrophin-1 may be a promising new metabolic biomarker in women with PCOS. CT-1 may be beneficial for estimating the risk of long-term adverse health consequences and establishing early intervention and preventation strategies. PMID- 29600729 TI - Astroglial 5-HT2B receptor in mood disorders. AB - INTRODUCTION: Astroglia represent the main cellular homeostatic system of the central nervous system (CNS). Astrocytes are intimately involved in regulation and maintenance of neurotransmission by regulating neurotransmitters removal and turnover and by supplying neurons with neurotransmitters precursors. Astroglial cells are fundamental elements of monoaminergic transmission in the brain and in the spinal cord. Astrocytes receive monoaminergic inputs and control catabolism of monoamines through dedicated transporters and intracellular enzymatic pathways. Areas covered: Astroglial cells express serotonergic receptors; in this review, we provide an in-depth characterization of 5-HT2B receptors. Activation of these receptors triggers numerous intracellular signaling cascades that regulate expression of multiple genes. Astroglial 5-HT2B receptors are activated by serotonin-specific reuptake inhibitors, such as major anti-depressant fluoxetine. Expression of astroglial serotonin receptors undergoes remarkable changes in depression disorders, and these changes can be corrected by chronic treatment with anti-depressant drugs. Expert commentary: Depressive behaviors, which occur in rodents following chronic stress or in neurotoxic models of Parkinson disease, are associated with significant changes in the expression of astroglial, but not neuronal 5-HT2B receptors; while therapy with anti depressants normalizes both receptors expression and depressive behavioral phenotype. In summary, astroglial serotonin receptors are linked to mood disorders and may represent a novel target for cell- and molecule-specific therapies of depression and mood disorders. PMID- 29600730 TI - Memory bias toward emotional information in burnout and depression. AB - A sample of 1015 educational staff members, exhibiting various levels of burnout and depressive symptoms, underwent a memory test involving incident encoding of positive and negative words and a free recall task. Burnout and depression were each found to be associated with increased recall of negative items and decreased recall of positive items. Results remained statistically significant when controlling for history of depressive disorders. Burnout and depression were not related to mistakes in the reported words, or to the overall number of recalled words. This study suggests that burnout and depression overlap in terms of memory biases toward emotional information. PMID- 29600731 TI - The diagnosis is correct, but National Institute of Health and Care Excellence guidelines are part of the problem not the solution. AB - Mike Scott's study provides data demonstrating that the national Improving Access to Psychological Therapies project is not leading to improved outcomes or value for money. I present further data from both the adult and children and young people's versions of Improving Access to Psychological Therapies that lends supports to this conclusion. However, while Scott argues in favour of better compliance with National Institute of Health and Care Excellence guidelines and greater model expertise, I argue that it is this 'technical' focus that is part of the problem not the solution. PMID- 29600732 TI - Five macrocyclic glycosides from Schoenoplectus tabernaemontani. AB - Macrocyclic glycosides with unique 22-membered dimeric lactone skeleton, are rare occurring natural products. There are only ten compounds reported so far. Herein we reported the isolation and characterisation of five macrocyclic glycosides from Schoenoplectus tabernaemontani, including three new compounds (Schoenopolide A-C, 1-3) and two known ones, Berchemolide (4) and Clemoarmanoside B (5). Their structures were established on the basis of extensive analysis of spectroscopic data. In addition, the anti-oxidative activity of Berchemolide (4) against H2O2 induced of renal tubular epithelial (HK-2) cells was also evaluated. PMID- 29600733 TI - Society and 'good woman': A critical review of gender difference in depression. AB - BACKGROUND: Worldwide, women are found to suffer from depression significantly more than men. This has puzzled the scientists since no biological explanation can completely resolve the matter. METHOD: Extant empirical work has been conducted to solve the mystery of the issue. However, most of the research has pivoted their attention to biology. Therefore, based on the previous literature from the disciplines of medicine, psychology and sociology, the author aimed at looking and reviewing the matter critically. Specifically, the present critical review aims at conceptualising the psychological, social and cultural factors in the context of gender difference in depression. DISCUSSION: The work reveals that psychological variables such as women's unique attachment patterns, relational self-construal, as well as a macro-level issue like power dynamics based on gender, and the skewed division of labour play an important role in gender difference in depression. The work also suggests that focusing solely on biological underpinnings may result in losing the entire scenario; therefore, social and cultural issues that place women in a socially disadvantaged position are equally important. PMID- 29600734 TI - Inhalation therapy for repairing damaged elastin fibers and decelerating elastinolysis in chronic obstructive pulmonary disease. AB - INTRODUCTION: Current pharmacologic therapy of chronic obstructive pulmonary disease (COPD) can reduce respiratory symptoms and exacerbation frequency. However, no single COPD intervention except for lung transplantation has proven effective in recovering lung function. Lung elasticity is reduced in COPD lungs, which is for a large part due to chronically enhanced elastin degradation. Elastin calcification and formation of advanced glycation end products (AGEs) may also contribute to this. Areas covered: We propose inhalation therapy to induce repair of damaged pulmonary elastin fibers by stimulating tropoelastin synthesis, assembly and crosslinking in order to improve lung function in patients with COPD. Decelerating elastinolysis is another treatment objective, as well as decalcification and deglycation of the extracellular matrix. Expert commentary: Studies should be conducted to test whether it is feasible to restore pulmonary elastin fibers with inhalation therapy. We expect that the optimal formulation will turn out to be a combination of copper, epigallocatechin-(3-)gallate or pentagalloyl glucose, vitamin A/D/K, magnesium, heparin or heparan sulfate, minoxidil and one or more AGEs inhibitors. Establishing a treatment that has the proven ability to facilitate regain of lost lung function in COPD patients would cause a major paradigm shift in this debilitating disease. PMID- 29600735 TI - Wastewater treatment for nutrient removal with Ecuadorian native microalgae. AB - The aim of this project was to study the feasibility of utilizing native microalgae for the removal of nitrogen and phosphorus, as a potential secondary wastewater treatment process in Ecuador. Agitation and aeration batch experiments were conducted using synthetic secondary wastewater effluent, to determine nitrogen and phosphorus removal efficiencies by a native Ecuadorian microalgal strain. Experimental results indicated that microalgal cultures could successfully remove nitrogen and phosphorus. [Formula: see text] and [Formula: see text] removal efficiencies of 52.6 and 55.6%, and 67.0 and 20.4%, as well as [Formula: see text] production efficiencies of 87.0 and 93.1% were reported in agitation and aeration photobioreactors, respectively. Aeration was not found to increase the nutrient removal efficiency of [Formula: see text]. Moreover, in the case of [Formula: see text], a negative impact was observed, where removal efficiencies decreased by a factor of 3.3 at higher aeration rates. To the best of our knowledge, this is the first report of the removal of nutrients by native Ecuadorian Chlorella sp., hence the results of this study would indicate that this native microalgal strain could be successfully incorporated in a potential treatment process for nutrient removal in Ecuador. PMID- 29600736 TI - Nutrient characterisation and bioenergy potential of common Nigerian food wastes. AB - Nigeria is the world's largest producer of yam, cassava, cocoyam/taro, beans/cowpea, egusi/melon seeds and among the largest producers of groundnut/peanut, plantain, corn/maize and ugwu/pumpkin leaves. These food crops generate unavoidable food wastes that can contribute to environmental degradation through unsanctioned waste disposal methods. Such food wastes can be utilised as feedstock for the anaerobic digestion (AD) process to produce renewable energy. In order to determine the suitability of the food wastes as biofuel feedstock, they were experimentally analysed. Their waste content was determined, characterised and used to evaluate their bio-methane potential. The tests were performed using standard proximate analytical methods while the bioenergy potential of the samples was determined using the Baserga model. Results indicated a specific waste index range of 0.2-1.5, with corn having the highest waste proportion. The proximate analysis results of the wastes were within the range of common AD feedstocks such as energy crops and plant by-products. The bio methane potentials of the samples varied widely with results ranging from 35-460 m3 tonne-1 on fresh weight and (5.4-6.2) * 105 m3 kg-1 on volatile solid basis. The methane potential varied between 51% and 58% of produced biogas. The energy potential of the food wastes was 31 TWh yr-1 which can make a substantial contribution to the bioenergy production of the country and meet up to the energy demand of 4.7 * 107 Nigerian households. Further studies would be required to determine the actual biogas yields of the food wastes. PMID- 29600737 TI - Statin prescription rates and their facility-level variation in patients with peripheral artery disease and ischemic cerebrovascular disease: Insights from the Department of Veterans Affairs. AB - The 2013 American College of Cardiology/American Heart Association cholesterol guideline recommends moderate to high-intensity statin therapy in patients with peripheral artery disease (PAD) and ischemic cerebrovascular disease (ICVD). We examined frequency and facility-level variation in any statin prescription and in guideline-concordant statin prescriptions in patients with PAD and ICVD receiving primary care in 130 facilities across the Veterans Affairs (VA) health care system between October 2013 and September 2014. Guideline-concordant statin intensity was defined as the prescription of high-intensity statins in patients with PAD or ICVD <=75 years and at least moderate-intensity statins in those >75 years. We calculated median rate ratios (MRR) after adjusting for patient demographic factors to assess the magnitude of facility-level variation in statin prescribing patterns independent of patient characteristics. Among 194,151 PAD patients, 153,438 patients (79.0%) were prescribed any statin and 79,435 (40.9%) were prescribed a guideline-concordant intensity of statin. PAD patients without ischemic heart disease were prescribed any statin and a guideline-concordant intensity of statin therapy less frequently (69.1% and 28.9%, respectively). Among 339,771 ICVD patients, 265,491 (78.1%) were prescribed any statin and 136,430 (40.2%) were prescribed a guideline-concordant intensity of statin. ICVD patients without ischemic heart disease were prescribed any statin and a guideline-concordant intensity of statin less frequently (70.9% and 30.5%, respectively). MRRs for both PAD and ICVD patients demonstrated a 20% and 28% variation among two facilities in treating two identical patients with statin therapy and guideline-concordant intensity of statin therapy, respectively. The prescription of statins, especially guideline-recommended intensity of statin therapy, is suboptimal in PAD and ICVD patients, with significant facility-level variation not explained by patient-level factors.

AB - BACKGROUND: The current screening tools for depression can be tedious to administer, especially in the elderly population with hearing impairment and/or limited proficiency in English language. OBJECTIVES: To look at the feasibility of using emoticon as a screening and assessment tool for depression in the elderly. DESIGN: Cross-sectional study. METHOD: A total of 77 elderly patients completed the study from June 2014 to August 2015 in a general geriatric outpatient clinic of an acute care hospital in Singapore. Patients rated their mood using an emoticon scale, which ranges from 1 ( most happy face) to 7 ( most sad face). Depression was assessed using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria as the gold standard. Sensitivity and specificity for depression were calculated for the cutoff scores from 1 to 7 on the emoticon scale. RESULTS: The sensitivity percentages were low across all cutoff scores. The specificity was more than 90% for the cutoff score of 5 and above on the emoticon scale. However, all the patients who had depression diagnosed using the DSM-IV criteria did not have emoticon scores of 5 and above. CONCLUSIONS: The emoticon scale was easy to use, but its effectiveness in the screening of depression in the elderly needs to be explored further. The inability to use the emoticon scale as a tool may be the lack of measurements in the other domains of the DSM-IV criteria (sleep, energy, appetite, etc.), rather than failure of the emoticon scale to assess mood. PMID- 29600741 TI - Photocatalytic degradation of phenazopyridine contaminant in soil with direct solar light. AB - Photocatalytic degradation of waste pharmaceutics, with solar radiation, is described here as a feasible method to purify pre-contaminated soils. Phenazopyridine has been used as a model soil contaminant. Two different nano size powders have been first examined as catalysts, namely commercial TiO2 (anatase) and commercial ZnO. As the ZnO showed higher catalytic efficiency, the study was then focused on it. The commercial ZnO powder was then compared with lab-prepared ZnO powder, and the latter shows relatively higher efficiency. The ZnO was used in two different ways. In one way, dry ZnO catalyst powder was spread onto the soil, while in the other way the ZnO was sprayed onto the soil surface by a wet spray method. The spray technique shows slightly higher efficiency, in addition to being easier to apply at future large scale. Depending on conditions and type of photocatalyst used, up to 90% contaminant removal can be achieved in 30 min. In case of photocatalysis experiments, the reacted contaminant molecules undergo complete degradation with no detectable side reaction organic products. Possible evaporation or escape of organic contaminant, or other possibly resulting organics, is ruled out by a series of control experiments. Photodegradation process takes place only at the catalytic sites on the soil surface, where contaminant molecules that diffuse from the soil bulk are completely degraded. Other useful organisms inside the soil are not affected as they are kept away from catalyst sites. A plausible mechanism is proposed for the degradation process.

AB - A new flavonoid, atalantraflavone (1) as well as eight known compounds including atalantoflavone (2), racemoflavone (3), 5,4'-dihydroxy-(3",4"-dihydro-3",4" dihydroxy)-2",2"-dimethylpyrano-(5",6":7,8)-flavone (4), lupalbigenin (5), anabellamide (6), citrusinine I (7), p-hydroxybenzaldehyde (8), and frideline (9), were isolated from the leaves of Atalantia monophylla (L.) DC. Focusing on Alzheimer's disease, acetylcholine esterase (AChE) inhibition and antioxidant activity were evaluated using the modified Ellman's method and the ABTS scavenging assay, respectively. It was found that isoflavonoid 5, lupalbigenin, showed 79% inhibition to AChE and was 1.4-fold stronger than the tacrine standard. In addition, acridone 7, citrusinine I, displayed 90.68% antioxidant activity. PMID- 29600743 TI - What types of recommendations are we giving patients? A survey of clinical neuropsychologists. AB - OBJECTIVE: To identify types of recommendations that neuropsychologists most frequently give to patients, and determine which specific recommendations are most and least consistently given to patients across and within different diagnostic populations. METHOD: A total of 309 clinical neuropsychologists completed a survey evaluating the frequency with which they made particular types of recommendations (e.g. driving, employment and education, health and rehabilitation referrals) to patients with various disorders (e.g. traumatic brain injury, dementia). RESULTS: Recommendations in some categories were common across diagnoses (e.g. recommendations related to health). Neuropsychologists reported being more likely to give patients with dementia (relative to other clinical populations) recommendations related to educational resources, supervision and independence, and driving. Patients with a TBI diagnosis were more likely to be given recommendations related to employment and education, health and rehabilitation referrals, and mental health and substance use. Patients with a psychiatric diagnosis were more likely to be given recommendations related to mental health and substance use. Irrespective of diagnosis, neuropsychologists reported being most likely to give recommendations that could be implemented by the patient or caregiver without assistance from outside sources. Neuropsychologists varied in their use of recommendations to seek evaluations and treatment from health and rehabilitation referrals and in providing recommendations related to driving. CONCLUSIONS: Recommendations provided within diagnostic groups are consistent with the etiology and prognosis of those conditions. Recommendations for the use of compensatory strategies to address cognitive deficits and recommendations to improve health were endorsed by the vast majority of neuropsychologists across diagnoses. PMID- 29600744 TI - Icelandic inclusion, German hesitation and American fear: A cross-cultural comparison of mental-health stigma and the media. AB - AIMS: Quantitative survey research findings reveal that Western countries have lower rates of public stigma surrounding mental illness than other nations. However, qualitative media research across selected Western countries reports differences in stigmatising messages. Here, we take an in-depth look at country level data exploring both similarities and differences in this stigma across three countries. Specifically, we use previous findings on global differences in public stigma and media to examine whether there is a correspondence between themes in newspaper reporting and variations in attitudes across seven stigma dimensions. METHODS: The Stigma in Global Context - Mental Health Study provides nationally representative data from Iceland ( N=1033; response rate=71%), Germany ( N=1255; response rate=63.16%) and the USA ( N=1425; response rate=67.31%). We limit analyses to respondents who received a vignette describing an individual meeting clinical criterion for schizophrenia or depression. Exploratory data analyses are used to examine overall patterns and cross-national differences. RESULTS: Graphical analyses show patterned similarities, especially for more individuals endorsing social distance as contact becomes more intimate. However, results also corroborate cross-national differences documented in media research. More Americans endorse evaluations of dangerousness, to both self and others. Fewer Icelanders report exclusionary tendencies, whilst Germans report the most consistently moderate levels of stigma. CONCLUSIONS: While Western nations tend to report similar, lower levels of stigma globally, they each have unique areas of concern. Anti-stigma programs must take note of both similarities and differences to tailor their efforts to the local context. PMID- 29600745 TI - Consult, Negotiate, and Involve: Evaluation of an Advanced Communication Skills Program for Health Care Professionals. AB - Effective communication is central to children, young people, and their families' experiences of health care. Most patient complaints in developed health care systems result from ineffective communication, including inadequate information provision, not feeling listened to, failure to value patients concerns, and patients not feeling involved in care decisions. Advanced communication skills training is now embedded within cancer care policy in the United Kingdom and now features prominently within cancer education in many countries. Here, we share findings from a research evaluation of an advanced communication skills training program dedicated to health professionals caring for children and young people with cancer. We evaluated participants' (n = 59) perceptions of the program, impact on their skills, knowledge, competence, and confidence. An appreciative inquiry design was adopted; data included interviews, precourse-postcourse evaluations, e-mail blog survey, and 360-degree reflective work records. The framework approach underpinned data analysis and triangulation of data sets. Key findings highlighted good and poor practice in health professionals' engagement with children, young people, and their families; the purpose of communicating effectively was not always consistent with collaborative working. Attending a program helped participants expand their knowledge of communication theories and strategies. Participants valued using simulated scenarios to develop their skills and were keen to use their new skills to enhance care delivery. Our emphasis within this evaluation, however, remained on what was communicated, when and how, rather than to what effect. The impact of programs such as these must now be evaluated in terms of patient benefit. PMID- 29600746 TI - "Hopefully This Will All Make Sense at Some Point": Meaning and Performance in Illness Blogs. AB - AIMS: To analyze the narratives of illness blogs created by parents of children with cancer. BACKGROUND: The profound effects of the childhood cancer experience on family members and the turn to the Internet by parents for help in the process are gaining research attention. DESIGN: The qualitative study design involved secondary narrative analysis of 14 illness blogs: 9 by the parents of children with neuroblastoma and 5 by the parents of children with leukemia. Daily blog entries were analyzed as individual units of illness experience expression and in relation to one another to identify thematic and linguistic similarities. METHODS: The initial analysis of these illness blogs resulted in identification of the quest for balance as a primary theme. Narratives in parents' childhood cancer illness blogs illustrated themes of performance. During this initial analysis, however, the author repeatedly asked, "Why are they writing this? And why publish this?" A second analysis of the data answered these questions of why parents blog about the experience. RESULTS: Narrative analysis resulted in the discovery of 6 main reasons that parents wrote and published the childhood cancer experience online: to report, explain, express, reflect, archive, and advocate. CONCLUSION: The analysis suggests that incorporation of parent writing may improve family--provider communication, enhance the family-health care professional relationship, enhance safety by preventing medical errors, improve reporting of clinical trial data such as adverse events, and improve satisfaction. PMID- 29600747 TI - The Effectiveness of a Hospital-Based School Liaison Program: A Comparative Study of Parental Perception of School Supports for Children With Pediatric Cancer and Neurofibromatosis Type 1. AB - Childhood survivors of central nervous system (CNS) cancers (defined as cancers whose diagnosis or treatment affect the CNS) are at increased risk for educational related difficulties, as are children affected by neurofibromatosis type 1. This study evaluated the effectiveness of and satisfaction with a model of psychoeducation, consultation, and advocacy provided by a School Liaison Program (SLP) for families and schools of children with CNS-involved cancers compared with a control group of parents of children with a diagnosis of neurofibromatosis type 1 who did not receive school-based services. Results indicated significant between-group differences in parents' belief that their child is meeting academic potential, with parents who received SLP services reporting greater satisfaction with their child's progress, better understanding of their child's learning needs, and an increased ability to access school supports. The strong, positive impact associated with the consultation, psychoeducation, and parental advocacy training provided by the SLP suggests that a similar model of care would potentially benefit other groups of children whose neurocognitive functioning is compromised by chronic medical conditions. PMID- 29600749 TI - Pigments from Filamentous Ascomycetes for Combination Therapy. AB - Filamentous ascomycetes (Neurospora and Monascus) have been studied for a long time because of their production of secondary metabolites such as microbial pigments. The ascomycetes represent an interesting group of compounds with high potential for medicinal applications. Many recent studies have shown their efficacy in the treatment of serious pathological states such as oncological diseases, neurodegenerative diseases and hyperlipidaemia. Nevertheless, the clinical usability of ascomycetes is still limited. However, this problem can be solved by use of these compounds with combinations of other therapeutic agents. This strategy can supress their side effects and improve their therapeutic efficiency. Moreover, their co-application can significantly enhance conventional therapies that are used. This review summarizes and discusses the general principles of this approach, introduced and supported by numerous examples. In addition, the prediction of the future potential application of this methodology is included. PMID- 29600750 TI - Terpenes, Phenylpropanoids, Sulfur and Other Essential Oil Constituents as Inhibitors of Cholinesterases. AB - Essential oils constituents are a diverse family of low molecular weight organic compounds with comprehensive biological activity. According to their chemical structure these active compounds can be divided into four major groups: terpenes, terpenoids, phenylpropenes, and "others". In addition, they may contain diverse functional groups according to which they can be classified as hydrocarbons (monoterpenes, sesquiterpenes, and aliphatic hydrocarbons); oxygenated compounds (monoterpene and sesquiterpene alcohols, aldehydes, ketones, esters, and other oxygenated compounds); and sulfur and/or nitrogen sulfur-containing compounds (thioesters, sulfides, isothiocyantes, nitriles, and others). Compounds that act as cholinesterase inhibitors still represent the only pharmacological treatment of Alzheimer's disease. Numerous in vitro studies showed that some compounds, found in essential oils, have a promising cholinesterase inhibitory activity, such as alpha-pinene, delta-3-carene, 1,8-cineole, carvacrol, thymohydroquinone, alpha- and beta-asarone, anethole, etc. This review summarizes the most relevant research published to date on essential oil constituents and their acetylcholinesterase/butyrylcholinesterase inhibitory potential as well as their structure related activity, synergistic and antagonistic effects. PMID- 29600751 TI - Electronegative LDL: an Active Player in Atherogenesis or a By-Product of Atherosclerosis? AB - Low-density lipoproteins (LDLs) are the major plasma carriers of cholesterol. However, LDL particles must undergo various molecular modifications to promote the development of atherosclerotic lesions. Modified LDL can be generated by different mechanisms, but as a common trait, show an increased electronegative charge of the LDL particle. A subfraction of LDL with increased electronegative charge (LDL(-)), which can be isolated from blood, exhibits several pro atherogenic characteristics. LDL(-) is heterogeneous, due to its multiple origins but is strongly related to the development of atherosclerosis. Nevertheless, the implication of LDL(-) in a broad array of pathologic conditions is complex and in some cases anti-atherogenic LDL(-) properties have been reported. In fact, several molecular modifications generating LDL(-) have been widely studied, but it remains unknown as to whether these different mechanisms are specific or common to different pathological disorders. In this review, we attempt to address these issues examining the most recent findings on the biology of LDL(-) and discussing the relationship between this LDL subfraction and the development of different diseases with increased cardiovascular risk. Finally, the review highlights the importance of minor apolipoproteins associated with LDL(-) which would play a crucial role in the different properties displayed by these modified LDL particles. PMID- 29600752 TI - Recent advances of mTOR inhibitors use in autosomal dominant polycystic kidney disease: is the road still open? AB - Autosomal dominant polycystic kidney disease (ADPKD), the most common monogenic kidney disease, is caused by mutations in the PKD1, PKD2 or, in a very limited number of families, GANAB genes. Although cellular and molecular mechanisms of this disease have been understood in the past 20 years, specific therapy approaches remain very little. Both experimental and clinical studies show that the mammalian or mechanistic target of rapamycin (mTOR) pathway plays an important role during cyst formation and enlargement in ADPKD. Studies in rodent models of ADPKD showed that mTOR inhibitors had a significant and long-lasting decrease in kidney volume and amelioration in kidney function. In the past over ten years, researchers have been devoting continuously to test mTOR inhibitors efficacy and safety in both preclinical studies and clinical trials in patients with ADPKD. In this review, we will discuss the mTOR pathway thoroughly, mainly focus on current advances in understanding its role in ADPKD, especially the recent progress of mTOR inhibitors use in preclinical studies and clinical trials. PMID- 29600753 TI - Bacterial Transferase MraY, a Source of Inspiration towards New Antibiotics. AB - The bacterial resistance to antibiotics constitutes more than ever a severe public health problem. The enzymes involved in bacterial peptidoglycan biosynthesis are pertinent targets for developing new antibiotics, notably the MraY transferase that is not targeted by any marketed drug. Many research groups are currently working on the study or the inhibition of this enzyme. After a concise overview of the role, mechanism and inhibition of MraY, the structure activity relationships of 5'-triazole-containing aminoribosyluridine inhibitors we previously synthetized will be presented. The recently published MraY X-ray structures allowed us to achieve a molecular virtual high-throughput screening of commercial data bases and our in-house library resulting in the identification of promising compounds for the further development of new antibiotics. PMID- 29600754 TI - In vitro Cytotoxicity and Genotoxicity Analysis of Ten Tannery Chemicals Using SOS/umu Tests and High-content In vitro Micronucleus Tests. AB - BACKGROUND: More than 2,000 chemicals have been used in the tannery industry. Although some tannery chemicals have been reported to have harmful effects on both human health and the environment, only a few have been subjected to genotoxicity and cytotoxicity evaluations. OBJECTIVE: This study focused on cytotoxicity and genotoxicity of ten tannery chemicals widely used in China. MATERIALS AND METHODS: DNA-damaging effects were measured using the SOS/umu test with Salmonella typhimurium TA1535/pSK1002. Chromosome-damaging and cytotoxic effects were determined with the high-content in vitro Micronucleus test (MN test) using the human-derived cell lines MGC-803 and A549. CONCLUSION: The cytotoxicity of the ten tannery chemicals differed somewhat between the two cell assays, with A549 cells being more sensitive than MGC-803 cells. None of the chemicals induced DNA damage before metabolism, but one was found to have DNA damaging effects on metabolism. Four of the chemicals, DY64, SB1, DB71 and RR120, were found to have chromosome-damaging effects. A Quantitative Structure-Activity Relationship (QSAR) analysis indicated that one structural feature favouring chemical genotoxicity, Hacceptor-path3-Hacceptor, may contribute to the chromosome-damaging effects of the four MN-test-positive chemicals. PMID- 29600755 TI - Virtual Screening of Novel Glucosamine-6-Phosphate Synthase Inhibitors. AB - BACKGROUND: Infections caused by microorganisms are the major cause of death today. The tremendous and improper use of antimicrobial agents leads to antimicrobial resistance. AIM AND OBJECTIVE: Various currently available antimicrobial drugs are inadequate to control the infections and lead to various adverse drug reactions. Efforts based on computer-aided drug design (CADD) can excavate a large number of databases to generate new, potent hits and minimize the requirement of time as well as money for the discovery of newer antimicrobials. Pharmaceutical sciences also have made development with advances in drug designing concepts. The current research article focuses on the study of various G-6-P synthase inhibitors from literature cited molecular database. Docking analysis was conducted and ADMET data of various molecules was evaluated by Schrodinger Glide and PreADMET software, respectively. Here, the results presented efficacy of various inhibitors towards enzyme G-6-P synthase. Docking scores, binding energy and ADMET data of various molecules showed good inhibitory potential toward G-6-P synthase as compared to standard antibiotics. This novel antimicrobial drug target G-6-P synthase has not so extensively been explored for its application in antimicrobial therapy, so the work done so far proved highly essential. This article has helped the drug researchers and scientists to intensively explore about this wonderful antimicrobial drug target. MATERIALS AND METHODS: The Schrodinger, Inc. (New York, USA) software was utilized to carry out the computational calculations and docking studies. The hardware configuration was Intel(r) core (TM) i5-4210U CPU @ 2.40GHz, RAM memory 4.0 GB under 64-bit window operating system. The ADMET data was calculated by using the PreADMET tool (PreADMET ver. 2.0). All the computational work was completed in the Laboratory for Enzyme Inhibition Studies, Department of Pharmaceutical Sciences, M.D. University, Rohtak, INDIA. RESULTS: Molecular docking studies were carried out to identify the binding affinities and interaction between the inhibitors and the target proteins (G-6-P synthase) by using Glide software (Schrodinger Inc. U.S.A. Maestro version 10.2). Grid-based Ligand Docking with Energetic (Glide) is one of the most accurate docking softwares available for ligand-protein, protein-protein binding studies. A library of hundreds of available ligands was docked against targeted proteins G-6-P synthase having PDB ID 1moq. Results of docking are shown in Table 1 and Table 2. Results of G-6-P synthase docking showed that some compounds were found to have comparable docking score and binding energy (kj/mol) as compared to standard antibiotics. Many of the ligands showed hydrogen bond interaction, hydrophobic interactions, electrostatic interactions, ionic interactions and pi- pi stacking with the various amino acid residues in the binding pockets of G-6-P synthase. CONCLUSION: The docking study estimated free energy of binding, binding pose andglide score and all these parameters provide a promising tool for the discovery of new potent natural inhibitors of G-6-P synthase. These G-6-P synthase inhibitors could further be used as antimicrobials. Here, a detailed binding analysis and new insights of inhibitors from various classes of molecules were docked in binding cavity of G-6-P synthase. ADME and toxicity prediction of these compounds will further accentuate us to study these compounds in vivo. This information will possibly present further expansion of effective antimicrobials against several microbial infections. PMID- 29600756 TI - Potential pharmacokinetic herb-drug interactions: have we overlooked the importance of human carboxylesterases 1 and 2? AB - Herbal products have grown steadily across the globe over the past 10 years and have increasingly been incorporated into western medicine for healthcare aims, thereby causing potential pharmacokinetic herb-drug interactions (HDI) through the inhibition or induction of drug-metabolizing enzymes and transporters. Human carboxylesterases 1 (CES1) and 2 (CES2) are versatile enzymes involvement in the metabolism of endogenous and exogenous compounds including many important therapeutic medications. Moreover, the growing number of CES substrate drugs also underscores the importance of CES1 and CES2. Here, we summarized those potential inhibitors and inducers coming from herbal constituents towards CES1 and CES2. We also reviewed those published HDI studies focusing on herbal products and therapeutic agents metabolized by CES1 or CES2. Our results showed that more than 50 natural inhibitors of CES1 or CES2 including phenolic chemicals, triterpenoids, and tanshinones were found from herbs, whereas inducers for both CES1 and CES2 are scarce. Systemic exposure to some commonly used drugs including oseltamivir, irinotecan, and clopidogrel were found to altered in animals when they were co-administered with herb products such as goldenseal, black cohosh, ginger, St John's Wort, curcumin, and Chinese compound formula. However, the HDI risk is likely to be low according to the very limited published data. Preclinical experimentation and clinical trials are warranted in the future to provide relevant safety data for the public especially for consumers and healthcare providers toward better clinical outcomes for herbal products and conventional drugs. PMID- 29600757 TI - Preclinical Hepatoprotective Effect of Herbalism Against Ethanol Induced Hepatotoxicity: A Review. AB - BACKGROUND: Liver ailments including alcoholic liver disease (ALD), still remain the main reason for morbidity & mortality worldwide. In fact, ALD is a multifactorial disease with complex pathophysiology which is linked to several types of liver damages including steatohepatitis, fibrosis and cirrhosis. METHODS: This review emphasizes on 30 herbal medicinal plants with their extracts studied for protective effect against ALD and current scientific evidence of ALD cure by thirty Indian Materia Medica including Tilia Platyphyllos, Amomum subulatum, Carica papaya, Pogostemon patchouli, Commelina benghalensis, Bacopamonnieri, Pecan nut, Allium cepa, Beta Vulgaris, Adina cordifolia, Ocimum gratissimum, Vernonia amygdalina, Sida veronicaefolia, Chenopodium album, Korean red ginseng, Elephantopus scaber, Tecomella undulata, Prunus armeniaca, Sea tangle (Laminaria japonica), Emblica officinalis, Saccharum officinarum, Cocculus hirsutus, Cassia roxburghii, Zhi-Zi-Da- Huang, Phyllanthus amarus, Aegle marmelos, Agrimonia eupatoria, Flaveria trinervia, Curcuma longa and Garcinia indica. RESULTS: Reduction in oxidative stress, improvement in inflammation, reduction in degeneration of fat and necrosis are some of the mechanisms of action of these medicinal plants observed in alcohol induced in-vivo and in-vitro liver injury models. CONCLUSION: Accordingly, this review provides several evidences which show that these medicinal plants could be used for the treatment and prevention of ALD. PMID- 29600758 TI - Indomethacin Analogs: Synthesis, Anti-inflammatory and Analgesic Activities of Indoline Derivatives. AB - BACKGROUND: Microwave assisted reactions offer a considerable advantages over conventional method reactions because the former results in substantial rate enhancement in a wide range of organic reactions. OBJECTIVE: we interested herein to prepare new anti-inflammatory and analgesic agents analogues to Indomethacin in short reaction time by using microwaves irradiation. METHOD: Synthesis of new hydrazonoindolines having thiazole moiety under microwave irradiation were achieved via the reaction of hydrazonoyl chlorides or halogenated active methylene derivatives with thiosemicarbazone derivatives. Also, the utility of the versatile indoline-2,3-dione derivatives in the design of new multifunctional building blocks using condensation with hydrazine derivatives was demonstrated. RESULTS: All products were formed in short reaction time and high yield. The information derived from the spectral data of the formed compounds was confirmed their structures. Also, the analgesic and antiinflammatory activities of the designed derivatives were screened and the results obtained indicated that six derivatives 4g, 9b, 4c, 10b, 4d and 11a revealed the highest anti-inflammatory and analgesic effects. CONCLUSION: we succeeded in this context to design and synthesis of new anti-inflammatory and analgesic agents analogues to Indomethacin in short reaction time and with high yield.

AB - BACKGROUND: The ultrasound assisted synthesis and anti-bacterial evaluation of a series of compounds based on 1,2-disubstituted benzimidazole framework is reported here. The approach leading to the synthesis of these compounds involved the Cu-catalyzed coupling-cyclization of N-substituted 2-iodoanilines with benzamide derivatives in the presence of 2-aminoethanol as a ligand. CONCLUSION: A number of compounds were prepared using this methodology in acceptable yield. Two of these compounds showed promising antibacterial activities when tested against both Gram-positive and Gram-negative bacterial strains. PMID- 29600761 TI - Development of Promising Thiopyrimidine-Based Anti-cancer and Antimicrobial Agents: Synthesis and QSAR Analysis. AB - New hybrids of thiopyrimidine-five/six heterocyclic rings were synthesized and in vitro evaluated for their antiproliferative activity against three human cancer cell lines, namely HCT116 (human colorectal carcinoma), PC-3 (human prostate adenocarcinoma) and HepG2 (human liver carcinoma) cell lines. The most potency was elicited by the target candidates against the viability of HCT116 cell lines, higher than the positive control 5-Fluorouracil (IC50 range; 0.11-0.49 uM, IC50, 5-FU; 1.10 uM). Cell cycle analysis and apoptosis activation revealed that compound 20 induced G2/M phase arrest and apoptosis in HCT116 cells. In addition, 20 activates the caspases-9 and -3, a process which might mediate the apoptosis of HCT116 cells. Quantitative structure activity relationship study was done and revealed a high predictive power R2 suggesting goodness of the models. Furthermore, there is a good agreement between the observed pIC50 and the predicted pIC50 values, in addition, the low RMSD and standard error values indicate the accuracy of the model. Antimicrobial evaluation revealed that some of these compounds exhibited significant activities against the tested pathogenic bacteria and fungi, wherein compounds 7a, 14, 15a, 21a, produced the most potent and broad spectrum antibacterial and antifungal potency equivalent to that revealed by Vibramycin and Ketoconazole (MIC; 125 MUg/mL). Moreover, compounds 15a, 21c, investigated dual potent antimicrobial and anticancer activity. PMID- 29600762 TI - Prodrugs of Non-steroidal Anti-inflammatory Drugs (NSAIDs): A Long March Towards Synthesis of Safer NSAIDs. AB - As a therapeutic group, non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used, prescribed and over the counter (OTC) medications for the treatment of inflammatory diseases, but suffering from several undesired side effects, the most important being ulcerogenicity, mucosal hemorrhage and gastritis. Most of the NSAID moieties are chemically composed of carboxylic functional groups and this could be one of the reasons for the damage to the mucosal lining. The prodrug designing is one of the several strategies used to overcome this drawback. Hence, in the last decade, the design and the synthesis of prodrugs of NSAIDs have been explored and given much attention by medicinal chemists. The rationale behind the prodrug concept is to achieve temporary blockade of the free carboxylic group present in the NSAIDs till their systemic absorption. This review is aimed to highlight and provide important information on NSAID prodrugs that have been designed and reported to be safe and more effective. This review will also focus on NSAID prodrugs that have been designed for improving therapeutic i.e. anti-inflammatory action as well as improving drug delivery at the target site. The most common derivatives of carboxylic NSAIDs that are discussed here belong to the chemical classes of esters, amides, anhydrides, acetals and the other derivatives with completely masked carboxylic groups. The successful prodrugs were listed and their molecular structures were also demonstrated here. The present review covers the recent updates present in literature and will surely provide a greater insight into the designing of safer NSAIDs in the future. PMID- 29600763 TI - Ryanodine Receptors for Drugs and Insecticides: An Overview. AB - Ryanodine receptors (RyRs) are calcium channels located on the endo(sarco)plasmic reticulum of muscle cells and neurons. They regulate release of stored intracellular calcium and play a critical role in muscle contraction. The N terminal part of these receptors accounts for roughly 80% and contains the binding sites for diverse RyRs modulators. The C-terminal domain contains the transmembrane region. Ryanodine, a plant alkaloid, has been investigated extensively as a potential pest control agent but no selectivity between mammalians and insect pests. The diamides (e.g., flubendiamide, cyantraniliprole and chlorantraniliprole) are the main commercial insecticides targeting insect RyRs. Due to the excessive application, amino acid mutations led to insect resistance to diamides. Furthermore, microRNA (miR-7a and miR-8519) could regulate overexpression of RyRs involved in chlorantraniliprole resistance, and lncRNAs are also associated with chlorantraniliprole resistance in Plutella xylostella. This review summarizes the current knowledge about the insect RyRs, their antagonists and activators, and the resistance mechanisms (including amino acid mutations, metabolic, genetic and fitness costs resistances, and miRNA and lncRNA in diamides resistances). This may lay the foundation for effective management of diamides resistances. PMID- 29600764 TI - Probing Gallic Acid for Its Broad Spectrum Applications. AB - Gallic acid and its derivatives not only exhibit excellent antioxidant, anticarcinogenic, antimutagenic, antimicrobial properties but also provide protection to the cells against oxidative stress. Gallic acid (3, 4, 5 trihydroxybenzoic acid), a low molecular triphenolic compound emerged as an efficient apoptosis inducing agent. The antimicrobial and other biological properties of gallic acid and its derivatives seemed to be linked with the hydrolysis of ester linkage between gallic acid and polyols like tannins hydrolyzed after ripening of many edible fruits. Gallic acid serves a natural defense mechanism against microbial infections and modulation of immune responses. The current review updates us with the diverse roles played by gallic acid, its antioxidant potential, action mechanism and more importantly the diverse array of applications in therapeutic and pharmaceutical areas. PMID- 29600765 TI - Network Pharmacology: Exploring the Resources and Methodologies. AB - Multi-target and combinatorial therapies have been focused for the past several decades. These approaches achieved considerable therapeutic efficacy by modulating the activities of the targets in complex diseases such as HIV-1 infection, cancer and diabetes disease. Most of the diseases cannot be treated efficiently in terms of single gene target, because it involves the cessation of the coordinated function of distinct gene groups. Most of the cellular components work efficiently by interacting with other cellular components and all these interactions together represent interactome. This interconnectivity shows that a defect in a single gene may not be restricted to the gene product itself, but may spread along the network. So, drug development must be based on the network-based perspective of disease mechanisms. Many systematic diseases like neurodegenerative disorders, cancer and cardiovascular cannot be treated efficiently by the single gene target strategy because these diseases involve the complex biological machinery. In clinical trials, many mono-therapies have been found to be less effective. In mono-therapies, the long term treatment, for the systematic diseases make the diseases able to acquired resistance because of the disease nature of the natural evolution of feedback loop and pathway redundancy. Multi-target drugs might be more efficient. Multi-target therapeutics might be less vulnerable because of the inability of the biological system to resist multiple actions. In this study, we will overview the recent advances in the development of methodologies for the identification of drug target interaction and its application in the poly-pharmacology profile of the drug. PMID- 29600766 TI - Discovering Synergistic Drug Combination from a Computational Perspective. AB - Synergistic drug combinations play an important role in the treatment of complex diseases. The identification of effective drug combination is vital to further reduce the side effects and improve therapeutic efficiency. In previous years, in vitro method has been the main route to discover synergistic drug combinations. However, many limitations of time and resource consumption lie within the in vitro method. Therefore, with the rapid development of computational models and the explosive growth of large and phenotypic data, computational methods for discovering synergistic drug combinations are an efficient and promising tool and contribute to precision medicine. It is the key of computational methods how to construct the computational model. Different computational strategies generate different performance. In this review, the recent advancements in computational methods for predicting effective drug combination are concluded from multiple aspects. First, various datasets utilized to discover synergistic drug combinations are summarized. Second, we discussed feature-based approaches and partitioned these methods into two classes including feature-based methods in terms of similarity measure, and feature-based methods in terms of machine learning. Third, we discussed network-based approaches for uncovering synergistic drug combinations. Finally, we analyzed and prospected computational methods for predicting effective drug combinations. PMID- 29600767 TI - Identification and Characterization of Positively Selected Mutations in Nef of Four HIV-1 Major Subtypes from Los Alamos National Laboratory. AB - BACKGROUND: Human immunodeficiency virus-1 (HIV-1) mutates rapidly to escape host immune pressure. This results in the generation of positively selected mutations (PSM) throughout the viral genome. Escape mutations in Nef, one of the accessory proteins of HIV-1, which plays an important role in viral pathogenicity have previously been identified in several large cohort studies, but the evolution of PSMs overtime in various HIV-1 subtypes remains unknown. METHODS: 161 clade A1, 3093 clade B, 647 clade C and 115 clade D HIV-1 nef sequences were obtained from the HIV Database of Los Alamos National Laboratory and aligned using MEGA 6.0. The sequences from each clade were grouped based on the year of collection. Quasi analysis was used to identify PSMs and the number and locations of PSMs were compared among different subtypes. RESULTS: PSMs for all four subtypes were distributed across the sequence of Nef, and conserved residues F90, W113, PxxPxR (a.a 72-77) remain unaltered overtime. The frequency of PSMs was stable among subtype B sequences but increased overtime for other subtypes. Phylogenetic analysis shows that sequences containing PSMs tend to cluster together at both inter and intra- subtype levels. CONCLUSION: Identification of PSMs and their changes overtime within various subtypes of HIV-1 is important in defining global viral evolutionary patterns that can provide insights for designing therapeutic strategies.

(Purslane) has been used in traditional medicine against hepatic injury, alt-hough its actual efficacy has not been fully understood. In addition, few studies have indicated that Portulaca oleracea L. possess protective effects against hepatotoxic agents. However, due to lack of information in human, more studies are needed to confirm the efficacy of Portulaca oleracea L. as a hepato-protective agent. The present study aimed to critically review the recent literature data from 1990 to 2017 regarding the hepato-protective effects of Portulaca oleracea L. and its underlying mechanisms. PMID- 29600770 TI - Antimicrobial Resistance: a One Health Perspective. AB - One Health is the collaborative effort of multiple health science professions to attain optimal health for people, domestic animals, wildlife, plants, and our environment. The drivers of antimicrobial resistance include antimicrobial use and abuse in human, animal, and environmental sectors and the spread of resistant bacteria and resistance determinants within and between these sectors and around the globe. Most of the classes of antimicrobials used to treat bacterial infections in humans are also used in animals. Given the important and interdependent human, animal, and environmental dimensions of antimicrobial resistance, it is logical to take a One Health approach when addressing this problem. This includes taking steps to preserve the continued effectiveness of existing antimicrobials by eliminating their inappropriate use and by limiting the spread of infection. Major concerns in the animal health and agriculture sectors are mass medication of animals with antimicrobials that are critically important for humans, such as third-generation cephalosporins and fluoroquinolones, and the long-term, in-feed use of medically important antimicrobials, such as colistin, tetracyclines, and macrolides, for growth promotion. In the human sector it is essential to prevent infections, reduce over prescribing of antimicrobials, improve sanitation, and improve hygiene and infection control. Pollution from inadequate treatment of industrial, residential, and farm waste is expanding the resistome in the environment. Numerous countries and several international agencies have included a One Health approach within their action plans to address antimicrobial resistance. Necessary actions include improvements in antimicrobial use regulation and policy, surveillance, stewardship, infection control, sanitation, animal husbandry, and alternatives to antimicrobials. WHO recently has launched new guidelines on the use of medically important antimicrobials in food-producing animals, recommending that farmers and the food industry stop using antimicrobials routinely to promote growth and prevent disease in healthy animals. These guidelines aim to help preserve the effectiveness of antimicrobials that are important for human medicine by reducing their use in animals.

AB - BACKGROUND: alpha-Solanine, the most important and active component of Solanum nigrum, was found to have anti-cancer activity on multiple cancer cells. However, its effects on colorectal cancer (CRC) and associated molecular mechanisms remain to be further elucidated. OBJECTIVE: In this study, we investigated the anti cancer effects of alpha-solanine against CRC cells in vitro and in vivo. MATERIALS & METHODS: Cell viability was measured using Cell Counting Kit-8 (CCK 8) assay; cell cycle was analyzed with a Cycletest Plus DNA Reagent Kit; cell apoptosis was detected by flow cytometer; cell migration and invasive ability was determined by Transwell assays; S100P protein expression was also analyzed by western blotting; lentiviral vectors expressing shRNA targeting the S100P gene. RESULTS: We demonstrated that alpha-solanine inhibited CRC cell (SW480, SW620 and HT-29) growth as well as migration and invasion, induced cell cycle arrest and apoptosis in vitro, and suppressed tumor growth in vivo. Moreover, we observed that S100P expression was downregulated by alpha-solanine. Overexpression of S100P partially reversed the alpha-solanine-induced growth inhibition of CRC cells. Conversely, knockdown of S100P by lentiviral-mediated RNAi resulted in significantly promoting the alpha-solanine-induced growth inhibition. CONCLUSION: These findings suggest that alpha-solanine is a potential agent for the treatment of CRC, and the anti-tumor effect of alpha-solanine in the CRC cells may be mediated at least partly by the downregulation of S100P. PMID- 29600771 TI - Antimicrobial Susceptibility Testing of Bacteria of Veterinary Origin. AB - Antimicrobial susceptibility testing is an essential tool to the veterinarian for selecting the most appropriate agent for treatment of bacterial diseases of animals. The availability of well-defined methods that incorporate the necessary quality controls coupled to clinical outcome data is foundational in providing relevant test results for clinical decisions. Since 1993, the Clinical Laboratory and Standards Institute (CLSI) Subcommittee on Veterinary Antimicrobial Susceptibility Testing (VAST) has developed specific test methods and interpretive criteria for veterinary pathogens. This information has allowed for veterinarians to more effectively treat animal diseases thereby protecting both animal welfare and human food security. Moreover, the availability of standardized test methods for veterinary pathogens has allowed for the development of antimicrobial surveillance programs to detect the emergence of resistance among veterinary pathogens. Future work by the VAST and other groups will be critical to expanding the current test methods and interpretive criteria to more pathogen-antibacterial combinations, as well as, the incorporation of genomic information for routine antimicrobial susceptibility testing in the veterinary diagnostic laboratory. PMID- 29600772 TI - Antimicrobial Resistance in Streptococcus spp. AB - The genus Streptococcus includes Gram-positive organisms shaped in cocci and organized in chains. They are commensals, pathogens, and opportunistic pathogens for humans and animals. Most Streptococcus species of veterinary relevance have a specific ecological niche, such as S. uberis, which is almost exclusively an environmental pathogen causing bovine mastitis. In contrast, S. suis can be considered as a true zoonotic pathogen, causing specific diseases in humans after contact with infected animals or derived food products. Finally, Streptococcus species such as S. agalactiae can be sporadically zoonotic, even though they are pathogens of both humans and animals independently. For clarification, a short taxonomical overview will be given here to highlight the diversity of streptococci that infect animals. Several families of antibiotics are used to treat animals for streptococcal infections. First-line treatments are penicillins (alone or in combination with aminoglycosides), macrolides and lincosamides, fluoroquinolones, and tetracyclines. Because of the selecting role of antibiotics, resistance phenotypes have been reported in streptococci isolated from animals worldwide. Globally, the dynamic of resistance acquisition in streptococci is slower than what is experienced in Enterobacteriaceae, probably due to the much more limited horizontal spread of resistance genes. Nonetheless, transposons or integrative and conjugative elements can disseminate resistance determinants among streptococci. Besides providing key elements on the prevalence of resistance in streptococci from animals, this article will also largely consider the mechanisms and molecular epidemiology of the major types of resistance to antimicrobials encountered in the most important streptococcal species in veterinary medicine.

AB - Ventricular tachycardia (VT) caused by a re-entrant circuit is a life-threatening arrhythmia that at present cannot always be treated adequately. A realistic model of re-entry would be helpful to accurately guide catheter ablation for interruption of the circuit. In this review, models of electrical activation wavefront propagation during onset and maintenance of re-entrant VT are discussed. In particular, the relationship between activation mapping and maps of transition in infarct border zone thickness, which results in source-sink mismatch, is considered in detail and supplemented with additional data. Based on source-sink mismatch, the re-entry isthmus can be modeled from its boundary properties. Isthmus boundary segments with large transitions in infarct border zone thickness have large source-sink mismatch, and functional block forms there during VT. These alternate with segments having lesser thickness change and therefore lesser source-sink mismatch, which act as gaps, or entrance and exit points, to the isthmus during VT. Besides post-infarction substrates, the source sink model is likely applicable to other types of volumetric changes in the myocardial conducting medium, such as when there is presence of fibrosis or dissociation of muscle fibers. PMID- 29600775 TI - Left Atrial Appendage Electrical Isolation for Treatment of Recurrent Atrial Fibrillation: A Meta-Analysis. AB - OBJECTIVES: In this study, the authors sought to perform a meta-analysis of controlled studies assessing the relationship between left atrial appendage (LAA) electrical isolation (EI) and recurrent atrial fibrillation (AF). BACKGROUND: LAA triggers could play an important role in AF and can be treated with complete EI of the LAA via surgical or percutaneous approaches. METHODS: We conducted a meta analysis of all controlled studies published as of November 21, 2016, assessing the relationship between left atrial appendage electrical isolation (LAAEI) and recurrent AF. The primary endpoint was atrial tachycardia (AT) or AF recurrence after the post-procedure blanking period. The association between LAAEI and AT/AF was estimated using random-effects modeling. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the DerSimonian and Laird method. RESULTS: We identified 7 studies including 1,037 patients; LAAEI was performed in 566 patients (55%). LAAEI was associated with a significantly lower rate of AT/AF recurrence in the primary analysis (OR: 0.38; 95% CI: 0.16 to 0.90; p = 0.02). The association between LAAEI and recurrent AT/AF was strongest in a sensitivity analysis restricted to studies of percutaneous LAAEI (OR: 0.22; 95% CI: 0.11 to 0.46; p < 0.001; 5 studies, n = 623). LAAEI was not associated with thromboembolism (OR: 0.50; 95% CI: 0.18 to 1.39; p = 0.18; 5 studies, n = 767), although these studies either incorporated LAA occlusion (3 studies, n = 552 patients) or follow-up echocardiography to assess LAA function (2 studies, n = 215 patients) to inform antithrombotic strategies. CONCLUSIONS: LAAEI is associated with a significant reduction in recurrent AT/AF. Randomized trials are required to confirm the efficacy and long-term safety of LAAEI and to determine the optimal concomitant antithrombotic strategy.

AB - OBJECTIVES: This study sought to test the accuracy of strain measurements based on anatomo-electromechanical mapping (AEMM) measurements compared with magnetic resonance imaging (MRI) tagging, to evaluate the diagnostic value of AEMM-based strain measurements in the assessment of myocardial viability, and the additional value of AEMM over peak-to-peak local voltages. BACKGROUND: The in vivo identification of viable tissue, evaluation of mechanical contraction, and simultaneous left ventricular activation is currently achieved using multiple complementary techniques. METHODS: In 33 patients, AEMM maps (NOGA XP, Biologic Delivery Systems, Division of Biosense Webster, a Johnson & Johnson Company, Irwindale, California) and MRI images (Siemens 3T, Siemens Healthcare, Erlangen, Germany) were obtained within 1 month. MRI tagging was used to determine circumferential strain (Ecc) and delayed enhancement to obtain local scar extent (%). Custom software was used to measure Ecc and local area strain (LAS) from the motion field of the AEMM catheter tip. RESULTS: Intertechnique agreement for Ecc was good (R2 = 0.80), with nonsignificant bias (0.01 strain units) and narrow limits of agreement (-0.03 to 0.06). Scar segments showed lower absolute strain amplitudes compared with nonscar segments: Ecc (median [first to third quartile]: nonscar -0.10 [-0.15 to -0.06] vs. scar -0.04 [-0.06 to -0.02]) and LAS (-0.20 [ 0.27 to -0.14] vs. -0.09 [-0.14 to -0.06]). AEMM strains accurately discriminated between scar and nonscar segments, in particular LAS (area under the curve: 0.84, accuracy = 0.76), which was superior to peak-to-peak voltages (nonscar 9.5 [6.5 to 13.3] mV vs. scar 5.6 [3.4 to 8.3] mV; area under the curve: 0.75). Combination of LAS and peak-to-peak voltages resulted in 86% accuracy. CONCLUSIONS: An integrated AEMM approach can accurately determine local deformation and correlates with the scar extent. This approach has potential immediate application in the diagnosis, delivery of intracardiac therapies, and their intraprocedural evaluation.

AB - OBJECTIVES: The purpose of this study was to describe and identify useful electrocardiographic characteristics to help identify the mechanism of atrial tachycardia (AT) occurring after persistent atrial fibrillation (PsAF) ablation. BACKGROUND: Electrocardiographic analysis to help identify the mechanism of AT after PsAF ablation is much limited by the fact that remodeling and ablation alter the normal activation pattern. METHODS: All consecutive patients who underwent mapping and ablation of AT after PsAF ablation were included. Surface P waves were analyzed during higher (>2:1) grades of atrioventricular block. RESULTS: One hundred ninety-six ATs with visible P waves were identified in 127 patients (macro-re-entry in 57%, centrifugal AT in 43%). One-third displayed low voltage P waves (<=0.1 mV). An isoelectric line >80 ms was more common in centrifugal compared with macro-re-entrant AT (47% vs. 24%; p < 0.001), but its positive predictive value was limited (60%). A minority of peritricuspid ATs displayed the classic saw-tooth pattern (27% [n = 22]). However, the "precordial transition" (a gradual transition from an upright component in lead V1 to a negative component with progression across the precordium) remained often observed and specifically identified peritricuspid AT (specificity, 98%; sensitivity, 59%). Only 2 unique features could help identify perimitral AT (n = 60). First, the presence of a negative or negative-positive P-wave in any of leads V2 to V6 identified perimitral AT with 97% specificity and 30% sensitivity. Second, a "notched" negative component at the beginning of a positive P-wave in the inferior leads specifically identified clockwise perimitral AT (specificity, 98%; sensitivity, 25%). CONCLUSIONS: Only few unique electrocardiographic characteristics help identify the mechanism of AT after PsAF ablation. Knowledge of these characteristics may aid in planning and performing ablation.

PMID- 29600786 TI - The Spatial Distribution of Late Gadolinium Enhancement of Left Atrial Magnetic Resonance Imaging in Patients With Atrial Fibrillation. AB - OBJECTIVES: The purpose of this study is to evaluate the spatial distribution of late gadolinium enhancement (LGE) of the left atrium (LA) by LGE-magnetic resonance imaging in an atrial fibrillation (AF) population. BACKGROUND: LGE of the LA can be a surrogate of pre-existing structural remodeling of LA. METHODS: LGE-magnetic resonance imaging scans were used for 160 patients with AF (mean age 66 +/- 11 years) before AF ablation. To know the spatial distribution of LGE, the extent of LGE in 6 LA subregions was examined. Overall LGE distribution was also summarized as a spatial frequency histogram using an atlas of LA shape. These data were also compared between paroxysmal AF (87 patients) and persistent AF (73 patients). RESULTS: LGE coverage (%) in each subregion was as follows: 41.8 +/- 18.9% in the left pulmonary vein (PV) antrum, 27.1 +/- 16.7% in the left lateral wall, 25.8 +/- 15.3% in the posterior wall, 19.7 +/- 15.3% in the anterior wall, 17.1 +/- 15.0% in the right PV antrum, and 12.0 +/- 13.2% in the septum wall. LGE was heterogeneously distributed in the LA and was found with the highest frequency in the posterior wall near the inferior left PV antrum by the LGE histogram. A comparison of paroxysmal AF with persistent AF suggests that LGE was more expected in persistent AF compared with paroxysmal AF, particularly with a spread on the posterior and the anterior wall. CONCLUSIONS: LGE in the LA was heterogeneously distributed. LGE was highly distributed in the inferior left PV antrum near the posterior wall side, and spread on the posterior and anterior wall with AF progression.

PMID- 29600788 TI - Transient Rotor Activity During Prolonged 3-Dimensional Phase Mapping in Human Persistent Atrial Fibrillation. AB - OBJECTIVES: This study sought to validate a 3-dimensional (3D) phase mapping system and determine the distribution of dominant propagation patterns in persistent atrial fibrillation (AF). BACKGROUND: Currently available systems display phase as simplified 2-dimensional maps. We developed a novel 3D phase mapping system that uses the 3D location of basket catheter electrodes and the patient's 3D left atrial surface geometry to interpolate phase and create a 3D representation of phase progression. METHODS: Six-min AF recordings from the left atrium were obtained in 14 patients using the Constellation basket catheter and analyzed offline. Exported signals underwent both phase and traditional activation analysis and were then visualized using a novel 3D mapping system. Analysis involved: 1) validation of phase analysis by comparing beat-to-beat AF cycle length calculated using phase inversion with that determined from activation timing in the same 20-s segment; 2) validation of 3D phase by comparing propagation patterns observed using 3D phase with 3D activation in the same 1-min segment; and 3) determining the distribution of dominant propagation patterns in 6-min recordings using 3D phase. RESULTS: There was strong agreement of beat-to-beat AF cycle length between activation analysis and phase inversion (R2 = 0.91). There was no significant difference between 3D activation and 3D phase in mean percentage of propagation patterns classified as single wavefronts (p = 0.99), focal activations (p = 0.26), disorganized activity (p = 0.76), or multiple wavefronts (p = 0.70). During prolonged 3D phase, single wavefronts were the most common propagation pattern (50.2%). A total of 34 rotors were seen in 9 of 14 patients. All rotors were transient with mean duration of 1.0 +/- 0.6 s. Rotors were only observed in areas of high electrode density where the interelectrode distance was significantly shorter than nonrotor sites (7.4 [interquartile range: 6.3 to 14.6] vs. 15.3 mm [interquartile range: 10.1 to 22.2]; p < 0.001). CONCLUSIONS: During prolonged 3D phase mapping, transient rotors were observed in 64% of patients and reformed at the same anatomic location in 44% of patients. The electrode density of the basket catheter may limit the detection of rotors. PMID- 29600789 TI - Now You See a Rotor, Now You Don't. PMID- 29600790 TI - Biatrial Electrical and Structural Atrial Changes in Heart Failure: Electroanatomic Mapping in Persistent Atrial Fibrillation in Humans. AB - OBJECTIVES: This study sought to characterize the biatrial substrate in heart failure (HF) and persistent atrial fibrillation (PeAF). BACKGROUND: Atrial fibrillation (AF) and HF frequently coexist; however, the contribution of HF to the biatrial substrate in PeAF is unclear. METHODS: Consecutive patients with PeAF and normal left ventricular (NLV) systolic function (left ventricular ejection fraction [LVEF] >55%) or idiopathic cardiomyopathy (LVEF <=45%) undergoing AF ablation were enrolled. In AF, pulmonary vein (PV) cycle length (PVCL) was recorded via a multipolar catheter in each PV and in the left atrial appendage for 100 consecutive cycles. After electrical cardioversion, biatrial electroanatomic mapping was performed. Complex electrograms, voltage, scarring, and conduction velocity were assessed. RESULTS: Forty patients, 20 patients with HF (mean age: 62 +/- 8.9 years; AF duration: 15 +/- 11 months; LVEF: 33 +/- 8.4%) and 20 with NLV (mean age: 59 +/- 6.7 years; AF duration: 14 +/- 9.1 months; p = 0.69; mean LVEF: 61 +/- 3.6%; p < 0.001), were enrolled. HF reduced biatrial tissue voltage (p < 0.001) with greater voltage heterogeneity (p < 0.001). HF was associated with significantly more biatrial fractionation (left atrium [LA]: 30% vs. 9%; p < 0.001; right atrium [RA]: 28% vs. 11%; p < 0.001), low voltage (<0.5 mV) (LA: 23% vs. 6%; p = 0.002; RA: 20% vs 11%; p = 0.006), and scarring (<0.05 mV) in the LA (p = 0.005). HF was associated with a slower average PVCL (185 vs. 164 ms; p = 0.016), which correlated significantly with PV antral bipolar voltage (R = -0.62; p < 0.001) and fractionation (R = 0.46; p = 0.001). CONCLUSIONS: HF is associated with significantly reduced biatrial tissue voltage, fractionation, and prolongation of PVCL. Advanced biatrial remodeling may have implications for invasive and noninvasive rhythm control strategies in patients with AF and HF.

PMID- 29600792 TI - Evaluation of a Strategy Aiming to Enclose the Pulmonary Veins With Contiguous and Optimized Radiofrequency Lesions in Paroxysmal Atrial Fibrillation: A Pilot Study. AB - OBJECTIVES: This study sought to evaluate the safety and the acute and 1 year outcomes of an ablation protocol aiming to enclose the PV with a contiguous and optimized RF circle by targeting region-specific criteria for lesion depth assessed by ablation index and interlesion distance. BACKGROUND: Reconnections after pulmonary vein (PV) isolation are explained by insufficient lesion depth and/or discontiguity of radiofrequency (RF) lesions. METHODS: A total of 130 consecutive patients with paroxysmal atrial fibrillation (AF) underwent PV encircling using a contact force-sensing catheter. RF was delivered targeting interlesion distance <=6 mm and ablation index >=400 at posterior wall and >=550 at anterior wall. Recurrence was defined as any AF, atrial tachycardia (AT), or atrial flutter (AFL) (AF/AT/AFL >30 s) on Holter electrocardiographs at 3, 6, and 12 months. RESULTS: Procedure and RF time per circle were 155 +/- 28 min and 17 +/- 5 min, respectively. Incidence of first-pass and adenosine-proof isolation were 98% and 98%, respectively. One short-lived transient ischemic attack was observed. At 12 months, single-procedure freedom from AF/AT/AFL was 91.3% in those 104 patients off antiarrhythmic drug therapy and 96.2% in those 26 patients on antiarrhythmic drug therapy. Single-procedure freedom from both AF/AT/AFL and antiarrhythmic drug therapy was 73.1%. CONCLUSIONS: This study suggests that an ablation protocol respecting strict criteria for lesion depth and contiguity results in acute durable PV isolation followed by a high single-procedure arrhythmia-free survival at 1 year. A prospective, multicenter trial is ongoing. PMID- 29600794 TI - Fluid collection after partial pancreatectomy: EUS drainage and long-term follow up. AB - Background and Objectives: Postoperative fluid collection due to pancreatic leak is the most frequent complication after pancreatic surgery. Endoscopic ultrasound (EUS)-guided drainage of post-pancreatic surgery fluid collection is the gold standard procedure; however, data on outcomes of this procedure are limited. The primary endpoint of our study was relapse over longterm followup, and the secondary endpoint was the efficiency and safety of EUS-guided drainage of post pancreatic surgery fluid collection. Patients and Methods: This retrospective study was conducted at a single center from December 2008 to April 2016. Global morbidity was defined as the occurrence of an event involving additional endoscopic procedures, hospitalization, or interventional radiologic or surgical procedures. EUS-guided drainage was considered a clinical failure if surgery was required to treat a relapse after stent removal. Results: Fortyone patients were included. The technical success rate was 100%. Drainage was considered a clinical success in 93% (39/41) of cases. Additionally, 19 (46%) complications were identified as global morbidity. The duration between surgery and EUS-guided drainage was not a significantly related factor for morbidity rate (P = 0.8); however, bleeding due to arterial injuries (splenic artery and gastroduodenal artery) from salvage drainage procedures occurred within 25 days following the initial surgery. There was no difference in survival between patients with and without complications. No relapse was reported during the followup (median: 44.75 months; range: 29.24 to 65.74 months). Conclusion: EUSguided drainage for post pancreatic surgery fluid collection was efficient with no relapse during longterm followup. Morbidity rate was independent of the duration between the initial surgery and EUS-guided drainage; however, bleeding risk was likely more important in cases of early drainage. PMID- 29600795 TI - No effect of abstinence time on nerve electrophysiological test in premature ejaculation patients. AB - The nerve electrophysiological tests may differentiate the treatment of primary premature ejaculation (PPE) in our previous studies. However, no study verifies if the results will be affected by abstinence time. From January to December in 2016, fifty PPE patients ejaculated within 2 min and 28 control subjects were enrolled. The nerve electrophysiological tests, including dorsal nerve somatosensory evoked potential (DNSEP), glans penis somatosensory evoked potential (GPSEP), and penile sympathetic skin response (PSSR), were recorded before and immediately after ejaculation. The abstinence day was not correlated with the latencies of SEPs or PSSR neither in PE group (P = 0.170, 0.064, and 0.122, respectively) nor in control group (P = 0.996, 0.475, and 0.904, respectively). No statistically differences were found in the latencies of SEPs and PSSR before and after ejaculation in PE patients (P = 0.439, 0.537, and 0.576, respectively) or control subjects (P = 0.102, 0.198, and 0.363, respectively). Thus, abstinence time does not interfere with the nerve electrophysiological test, which is stable in determining the nerve function of PPE patients. PMID- 29600796 TI - Rapid screening for Klinefelter syndrome with a simple high-resolution melting assay: a multicenter study. AB - Klinefelter syndrome (KS) is the set of symptoms that result from the presence of an extra X chromosome in males. Postnatal population-based KS screening will enable timely diagnosis of this common chromosomal disease, providing the opportunity for early intervention and therapy at the time point when they are most effective and may prevent later symptoms or complications. Therefore, through this study, we introduced a simple high-resolution melting (HRM) assay for KS screening and evaluated its clinical sensitivity and specificity in three medical centers using 1373 clinical blood samples. The HRM assay utilized a single primer pair to simultaneously amplify specific regions in zinc finger protein, X-linked (ZFX) and zinc finger protein, Y-linked (ZFY). In cases of KS, the ratios of ZFX/ZFY are altered compared to those in normal males. As a result, the specific melting profiles differ and can be differentiated during data analysis. This HRM assay displayed high analytical specificity over a wide range of template DNA amounts (5 ng-50 ng) and reproducibility, high resolution for detecting KS mosaicism, and high clinical sensitivity (100%) and specificity (98.1%). Moreover, the HRM assay was rapid (2 h per run), inexpensive (0.2 USD per sample), easy to perform and automatic, and compatible with both whole blood samples and dried blood spots. Therefore, this HRM assay is an ideal postnatal population-based KS screening tool that can be used for different age groups. PMID- 29600797 TI - Authors' reply.

AB - BACKGROUND Hypertonic saline (HS) has been successfully used for treatment of various forms of brain edema. Decreased expression of aquaporin (AQP)4 and pro inflammatory cytokines such as tumor necrosis factor (TNF)-a and interleukin (IL) 1b have been linked to edema pathogenesis. This study examined the effect of 3% HS on brain edema in a rat model of traumatic brain injury (TBI). MATERIAL AND METHODS Sprague-Dawley rats were subjected to TBI induced by a controlled cortical impactor. The HS group was injected with 3% NaCl until the end of the study period. AQP4, TNF-alpha, IL-1beta, and caspase-3 levels were measured by Western blotting, immunohistochemistry, enzyme-linked immunosorbent assay, and quantitative real-time PCR. Brain water content was also measured. Apoptotic cells in brain tissue were detected with terminal deoxynucleotidyl transferase dUTP nick-end labeling. Brain water content decreased following treatment with 3% HS relative to the TBI group. RESULTS This was accompanied by decreases in AQP4, TNF-alpha, and IL-1beta mRNA and protein levels. TBI resulted in increases in caspase-3 mRNA expression and the number of apoptotic cells; treatment with 3% HS suppressed apoptosis as compared to the TBI group. CONCLUSIONS Treatment with 3% HS ameliorated TBI-induced brain edema, possibly by suppressing brain edema, pro inflammatory cytokine expression, and apoptosis.

AB - Objective: The purpose of this article is to describe the background and experience of the Academic-Community Engagement (ACE) Core of the Mid-South Transdisciplinary Collaborative Center for Health Disparities Research (Mid-South TCC) in impacting the social determinants of health through the establishment and implementation of a regional academic-community partnership. Conceptual Framework: The Mid-South TCC is informed by three strands of research: the social determinants of health, the socioecological model, and community-based participatory research (CBPR). Combined, these elements represent a science of engagement that has allowed us to use CBPR principles at a regional level to address the social determinants of health disparities. Results: The ACE Core established state coalitions in each of our founding states-Alabama, Louisiana, and Mississippi-and an Expansion Coalition in Arkansas, Tennessee, and Kentucky.

AB - STUDY OBJECTIVE: To determine the influence of anticholinergic medications on transitions in cognitive diagnosis of older adults in primary care. DESIGN: This observational cohort study was conducted over a mean follow-up of 3.2 years. Anticholinergic exposure was defined by pharmacy dispensing and claims records. Cognitive diagnosis was performed by an expert panel at baseline and annually up to 4 years. DATA SOURCE: Medication exposure and other clinical data were extracted from the Indiana Network for Patient Care (INPC). The cognitive diagnosis was derived from a cognitive screening and diagnosis study. PARTICIPANTS: A total of 350 adults 65 years and older without dementia and receiving primary care in a safety net health care system. MEASUREMENT AND MAIN RESULTS: Cognitive diagnosis followed a two-phase screening and consensus-based neuropsychiatric examination to determine a baseline diagnosis as normal cognition, mild cognitive impairment (MCI), or dementia, with a follow-up neuropsychiatric examination and consensus-based diagnosis repeated annually. The Anticholinergic Cognitive Burden scale was used to identify anticholinergics dispensed up to 10 years before enrollment and annually throughout the study. A total standard daily dose of anticholinergics was calculated by using pharmacy dispensing data from the INPC. Among 350 participants, a total of 978 diagnostic assessments were completed over a mean follow-up of 3.2 years. Compared with stable cognition, increasing use of strong anticholinergics calculated by total standard daily dose increased the odds of transition from normal cognition to MCI (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.01-1.31, p = 0.0342). Compared with stable MCI, strong anticholinergics did not influence the reversion of MCI to normal cognition (OR 0.95, 95% CI 0.86-1.05, p = 0.3266). CONCLUSION: De-prescribing interventions in older adults with normal cognition should test anticholinergics as potentially modifiable risk factors for cognitive impairment.

AB - OBJECTIVE: To compare stereotactic radiosurgery (SRS) versus anterior temporal lobectomy (ATL) for patients with pharmacoresistant unilateral mesial temporal lobe epilepsy (MTLE). METHODS: This randomized, single-blinded, controlled trial recruited adults eligible for open surgery among 14 centers in the USA, UK, and India. Treatment was either SRS at 24 Gy to the 50% isodose targeting mesial structures, or standardized ATL. Outcomes were seizure remission (absence of disabling seizures between 25 and 36 months), verbal memory (VM), and quality of life (QOL) at 36-month follow-up. RESULTS: A total of 58 patients (31 in SRS, 27 in ATL) were treated. Sixteen (52%) SRS and 21 (78%) ATL patients achieved seizure remission (difference between ATL and SRS = 26%, upper 1-sided 95% confidence interval = 46%, P value at the 15% noninferiority margin = .82). Mean VM changes from baseline for 21 English-speaking, dominant-hemisphere patients did not differ between groups; consistent worsening occurred in 36% of SRS and 57% of ATL patients. QOL improved with seizure remission. Adverse events were anticipated cerebral edema and related symptoms for some SRS patients, and cerebritis, subdural hematoma, and others for ATL patients. SIGNIFICANCE: These data suggest that ATL has an advantage over SRS in terms of proportion of seizure remission, and both SRS and ATL appear to have effectiveness and reasonable safety as treatments for MTLE. SRS is an alternative to ATL for patients with contraindications for or with reluctance to undergo open surgery. PMID- 29600810 TI - Tinea pedis acquired in mosques? AB - We present four cases of interdigital tinea pedis in Italian tourists which was probably acquired in Turkish mosques and holy Muslim places. In all patients mycological examinations were positive for Trichophyton rubrum. All patients were successfully treated with bifonazole cream (one application/day for three weeks). It is advisable for tourists to wear socks when visiting mosques and holy Muslim places. PMID- 29600811 TI - Outcome prediction in patients with acute repetitive seizures: Application of the Status Epilepticus Severity Score. AB - Acute repetitive seizures (ARS) pose a risk of hospital admission with status epilepticus and a mortality threat, which underscores the need for the early prediction of a clinical course. Unfortunately, little attention has been given to ARS in this context, even though we possess the appropriate predictive tools for the stages of status epilepticus. Therefore, the main aim of this study was to assess the prognostic value of the Status Epilepticus Severity Score (STESS) in the population of patients with ARS. The study included a population of 200 patients. Almost half of the patients had achieved seizure cessations after diazepam administration, whereas 19.5% progressed to status epilepticus despite antiepileptic drug treatment. Mortality reached 10.5% of the total population. The receiver operating characteristic (ROC) curve for prediction of death by the STESS had an area under the curve (AUC) of 0.901, with an optimal cutoff point for discrimination >=2 (sensitivity 0.95, specificity 0.71, and Youden index 0.66). Hosmer-Lemeshow indicated good calibration of the STESS (chi-square goodness-of-fit test = 3.24; P = .919). The study shows excellent effectiveness of the STESS in the prognosis of the clinical course in patients with ARS. STESS may be a valuable tool for the proper planning of diagnostic and therapeutic activities in this population. PMID- 29600812 TI - Ion trajectory simulations of a conical octopole ion guide and its comparison with a parallel one in chemical ionization mass spectrometric applications. AB - RATIONALE: Focusing and transmission are important characteristics of ion transportation in mass spectrometric applications. An ion guide device is an essential component in a mass spectrometer, especially when chemical ionization is employed. We present a conical octopole ion guide and its comparison with a parallel counterpart for simulating the ion trajectories through the ion guide and the quadrupole mass analyzer. METHODS: Ion trajectory simulations using SIMION 8.0 were performed to evaluate the performance of both conical and parallel octopole ion guides and the overall ion transmission through combining the octopole ion guide and the quadrupole mass analyzer in the mass spectrometer. Through the simulations, parameters that control the ion guide were optimized for the focus and transport of weakly bonded cluster ions, including the DC bias voltage, the frequency and the amplitude of the sine wave applied to the guide. RESULTS: The results from ion trajectory simulations showed that the ion beam can be highly focused from initially 10 mm down to 2 mm in diameter for the conical octopole ion guide. The transmission efficiencies are dependent on the mass of the ion, the frequency and amplitude of the radiofrequency waveform applied to the octopoles. The simulated overall transmission efficiencies of the conical ion guide are consistent with the observed sensitivities from the previously reported calibration experiments in the low-mass region but are much higher than those in the high-mass region (i.e., masses greater than 400 amu). CONCLUSIONS: The simulations showed that the conical octopole ion guide can efficiently transport ions with high focusing through differentially pumped vacuum chambers. However, the overall transmission efficiencies of the conical octopole ion guide are in general lower than the parallel one when combined with the quadrupole mass analyzer based on the assumed exponential pressure gradient along the axial of the octopole ion guide. PMID- 29600816 TI - Comparison of chlorhexidine-isopropanol with isopropanol skin antisepsis for prevention of surgical-site infection after abdominal surgery. AB - BACKGROUND: Prevention of surgical-site infection (SSI) has received increasing attention. Clinical trials have focused on the role of skin antisepsis in preventing SSI. The benefit of combining antiseptic chlorhexidine with alcohol has not been compared with alcohol-based skin preparation alone in a prospective controlled clinical trial. METHODS: Between August and October 2014, patients undergoing abdominal surgery received preoperative skin antisepsis with 70 per cent isopropanol (PA). Those treated between November 2014 and January 2015 received 2 per cent chlorhexidine with 70 per cent isopropanol (CA). The primary endpoint was SSI on postoperative day (POD) 10, which was evaluated using univariable analysis, and a multivariable logistic regression model correcting for known independent risk factors for SSI. The study protocol was published in the German Registry of Clinical Studies (DRKS00011174). RESULTS: In total, 500 patients undergoing elective midline laparotomy were included (CA 221, PA 279). The incidence of superficial and deep SSIs was significantly different on POD 10: 14 of 212 (6.6 per cent) among those treated with CA and 32 of 260 (12.3 per cent) in those who received PA (P = 0.038). In the multivariable analysis, skin antisepsis with CA was an independent factor for reduced incidence of SSI on POD 10 (P = 0.034). CONCLUSION: This study showed a benefit of adding chlorhexidine to alcohol for skin antisepsis in reducing early SSI compared with alcohol alone. PMID- 29600817 TI - Nurses' perception of how an e-message system influences cross-sectoral communication: A qualitative study. AB - AIM: To investigate hospital and home care nurses' experiences on how an e message system influences cross-sectoral communication 2 years after introduction. BACKGROUND: Cross-sectoral communication is identified as the main barrier for high quality in transitional care. An e-message system was introduced to ensure dialogue and precise and useful information exchange. METHODS: Nurses from one hospital and six collaborating municipalities were included. Semi structured focus group interviews and participation observation was conducted and data were analysed using content analysis. RESULTS: The e-message system was used in both sectors but did not promote cross-sectoral dialogue. The home care nurses expressed distrust in the information from the hospital. The hospital nurses' intention was to provide relevant and accurate information but their main focus was to fulfil the standards within the system rather than the quality of the information exchanged. CONCLUSIONS: The e-message system supports a one-way information flow, rather than the intended loop of information exchange and dialogue. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should recognise that although an e-message system is being used in a clinical setting, it may not support exchange of high-quality information and dialogue. Focus must be on both standards as well as quality when new systems are introduced. PMID- 29600818 TI - Emergence of Uranium as a Distinct Metal Center for Building Intrinsic X-ray Scintillators. AB - The combination of high atomic number and high oxidation state in UVI materials gives rise to both high X-ray attenuation efficiency and intense green luminescence originating from ligand-to-metal charge transfer. These two features suggest that UVI materials might act as superior X-ray scintillators, but this postulate has remained substantially untested. Now the first observation of intense X-ray scintillation in a uranyl-organic framework (SCU-9) that is observable by the naked eye is reported. Combining the advantage in minimizing the non-radiative relaxation during the X-ray excitation process over those of inorganic salts of uranium, SCU-9 exhibits a very efficient X-ray to green light luminescence conversion. The luminescence intensity shows an essentially linear correlation with the received X-ray intensity, and is comparable with that of commercially available CsI:Tl. SCU-9 possesses an improved X-ray attenuation efficiency (E>20 keV) as well as enhanced radiation resistance and decreased hygroscopy compared to CsI:Tl. PMID- 29600819 TI - Association Between Medication Adherence and the Outcomes of Heart Failure. AB - BACKGROUND: Previous studies of heart failure patients demonstrated an association between cardiovascular medication adherence and hospitalizations or a composite end point of hospitalization and death. Few studies have assessed the impact of treatment adherence within large general medical populations that distinguish the health outcomes of emergency department visits, hospitalization, and death. OBJECTIVE: To determine the association of incremental cardiovascular medication adherence on emergency department visits, hospitalization, and death in adult heart failure patients in Indiana. DESIGN: Retrospective cohort study conducted using electronic health record data from the statewide Indiana Network for Patient Care between 2004 and 2009. METHODS: Patients were at least 18 years of age with a diagnosis of heart failure and prescribed at least one cardiovascular medication for heart failure. Adherence was measured as the proportion of days covered (PDC) using pharmacy transaction data. Clinical end points included emergency department visits, hospital admissions, length of hospital stay, and mortality. Generalized linear models were used to determine the effect of a 10% increase in PDC on clinical end points adjusting for age, sex, race, Charlson Comorbidity Index, and medications. RESULTS: Electronic health records were available for 55,312 patients (mean age +/- standard deviation 68 +/- 16 yrs; 54% women; 65% white). Mean PDC for all heart failure medications was 63% +/- 23%. For every 10% increase in PDC, emergency department visits decreased 11% (rate ratio [RR] 0.89, 95% confidence interval [CI] 0.89 0.89), hospital admissions decreased 6% (RR 0.94, 95% CI 0.94-0.94), total length of hospital stay decreased 1% (RR 0.99, 95% CI 0.99-1.00), and all-cause mortality decreased 9% (odds ratio 0.91; 95% CI 0.90-0.92). CONCLUSION: Incremental medication adherence was associated with reductions in emergency department visits, hospital admissions, length of hospital stay, and all-cause mortality. PMID- 29600820 TI - Connection-based and object-based grouping in multiple-object tracking: A developmental study. AB - Developmental research on Gestalt laws has previously revealed that, even as young as infancy, we are bound to group visual elements into unitary structures in accordance with a variety of organizational principles. Here, we focus on the developmental trajectory of both connection-based and object-based grouping, and investigate their impact on object formation in participants, aged 9-21 years old (N = 113), using a multiple-object tracking paradigm. Results reveal a main effect of both age and grouping type, indicating that 9- to 21-year-olds are sensitive to both connection-based and object-based grouping interference, and tracking ability increases with age. In addition to its importance for typical development, these results provide an informative baseline to understand clinical aberrations in this regard. Statement of contribution What is already known on this subject? The origin of the Gestalt principles is still an ongoing debate: Are they innate, learned over time, or both? Developmental research has revealed how each Gestalt principle has its own trajectory and unique relationship to visual experience. Both connectedness and object-based grouping play an important role in object formation during childhood. What does this study add? The study identifies how sensitivity to connectedness and object-based grouping evolves in individuals, aged 9-21 years old. Using multiple-object tracking, results reveal that the ability to track multiple objects increases with age. These results provide an informative baseline to understand clinical aberrations in different types of grouping. PMID- 29600821 TI - An unusual presentation of a common condition: Allergic contact dermatitis. AB - Allergic contact dermatitis commonly affects patients with chronic venous leg ulcers and can contribute to impaired wound healing. Many allergens have been identified, and despite the use of advanced dressings, the incidence of allergy has remained high. We discuss an unusual presentation of allergic contact dermatitis in a patient with a chronic wound. The patient's history was consistent with a recurrent venous leg ulcer, but on this occasion, the wound continued to deteriorate despite optimal treatment. This prompted further investigation, which included patch testing. Although the clinical features were not suggestive of allergy, the patch test was positive for several allergens, including Atrauman(r) dressings, which the patient was using at the time. This case highlights the importance of regular reassessment and accurate diagnosis for the management of chronic wounds. It also demonstrates that allergic contact dermatitis can contribute to delayed wound healing without causing the classical clinical features of inflammation of the surrounding skin, and even hypoallergenic, non-adherent dressings can be sensitising. PMID- 29600822 TI - Effect of an experiential learning-based programme to foster competence among nurse managers. AB - AIM: The present study aimed to examine the effect of providing an experiential learning-based programme to foster competence among nurse managers in the early years of their supervisory roles. BACKGROUND: Nurse managers take supervisory positions without being sufficiently prepared for the task and therefore often experience difficultly in the early years of managerial roles. They need support from their supervisor and require opportunities for development. METHODS: We developed an experiential learning-based programme for nurse managers in the first 3 years of a supervisory role. Sixty-three nurse managers and their supervisors were enrolled. The programme was evaluated using a one-group pretest posttest design. The outcome measures were experiential learning, knowledge, social support, competency as a nurse manager, and sense of coherence. Outcomes were compared using paired t tests. RESULTS: Nurse managers showed significantly improved experiential learning (p = .001), knowledge (p < .001) and competence as a nurse manager (p = .002) after participating in this programme. CONCLUSION: This programme increased knowledge, promoted experiential learning, and improved competence among nurse managers. IMPLICATIONS FOR NURSING MANAGEMENT: This experiential learning-based programme for nurse managers in the early years of a supervisory role fostered competence among nurse managers. PMID- 29600823 TI - Realization of Walnut-Shaped Particles with Macro-/Mesoporous Open Channels through Pore Architecture Manipulation and Their Use in Electrocatalytic Oxygen Reduction. AB - Herein we report a simple dual-soft-template approach to prepare walnut-shaped macro-/mesoporous polydopamine particles with diameter of ca. 270 nm, highly accessible bicontinuous channels and wide pore size distribution from ca. 20 nm to ca. 95 nm. This approach provides great opportunities to tailor the soft template-directed assembly processes and generate various polydopamine particles with controllable mesophase curvature. Walnut-shaped mesoporous carbon particles with large open mesochannels in the range of ca. 13 nm to ca. 50 nm can be fabricated by subsequent thermal treatment under nitrogen atmosphere. Lastly, we demonstrate that the as-derived walnut-shaped carbon particles manifest enhanced electrocatalytic performance for oxygen reduction reaction in alkaline electrolyte. PMID- 29600824 TI - Prospective Open-label Trial of Early Concomitant Vasopressin and Norepinephrine Therapy versus Initial Norepinephrine Monotherapy in Septic Shock. AB - PURPOSE: Delays in achieving target mean arterial pressure (MAP) are associated with increased morbidity and mortality in patients with septic shock. This trial was conducted to test the hypothesis that early concomitant treatment with vasopressin and norepinephrine reduces the time to achieve and maintain target MAP compared with initial norepinephrine monotherapy. METHODS: A single-center prospective open-label trial was conducted in patients with septic shock between November 2015 and June 2016 at a medical intensive care unit in an academic medical center. Initial norepinephrine monotherapy was initiated between November 2015 and February 2016. Between March and June 2016, vasopressin was initiated within 4 hours of norepinephrine. The primary outcome was time to achieving and maintaining MAP of 65 mm Hg for at least 4 hours that was compared between groups using the Student t test and examined using the Kaplan-Meier curve (Clinical Trials registration: NCT02454348). RESULTS: Eighty-two patients were included (41 in each group). Patients treated with early concomitant vasopressin and norepinephrine more frequently had a positive culture (59% vs 37%, p=0.05) and grew nonlactose fermenting gram-negative bacilli (34% vs 10%, p=0.01) compared with patients treated with norepinephrine monotherapy, respectively. The median time to achieve and maintain MAP occurred faster in the early concomitant vasopressin and norepinephrine group, at 5.7 hours (interquartile range [IQR] 1.7 10.3 hrs), compared with 7.6 hours (IQR 3.6-16.7 hrs, p=0.058) in the norepinephrine group. Durations of therapy for norepinephrine or vasopressin, amount of norepinephrine received in the first 24 hours, norepinephrine dosage when MAP was achieved and maintained, maximum norepinephrine dosage, and mortality were similar between groups. CONCLUSION: Patients treated with early concomitant vasopressin and norepinephrine achieved and maintained MAP of 65 mm Hg faster than those receiving initial norepinephrine monotherapy, suggesting that overcoming vasopressin deficiency sooner may reduce the time patients spend in the early phase of septic shock. PMID- 29600825 TI - Depression comorbidity in epileptic rats is related to brain glucose hypometabolism and hypersynchronicity in the metabolic network architecture. AB - OBJECTIVE: Temporal lobe epilepsy (TLE) is one of the most common types of epilepsy syndromes in the world. Depression is an important comorbidity of epilepsy, which has been reported in patients with TLE and in different experimental models of epilepsy. However, there is no established consensus on which brain regions are associated with the manifestation of depression in epilepsy. Here, we investigated the alterations in cerebral glucose metabolism and the metabolic network in the pilocarpine-induced rat model of epilepsy and correlated it with depressive behavior during the chronic phase of epilepsy. METHODS: Fluorodeoxyglucose (18 F-FDG) was used to investigate the cerebral metabolism, and a cross-correlation matrix was used to examine the metabolic network in chronically epileptic rats using micro-positron emission tomography (microPET) imaging. An experimental model of epilepsy was induced by pilocarpine injection (320 mg/kg, ip). Forced swim test (FST), sucrose preference test (SPT), and eating-related depression test (ERDT) were used to evaluate depression-like behavior. RESULTS: Our results show an association between epilepsy and depression comorbidity based on changes in both cerebral glucose metabolism and the functional metabolic network. In addition, we have identified a significant correlation between brain glucose hypometabolism and depressive-like behavior in chronically epileptic rats. Furthermore, we found that the epileptic depressed group presents a hypersynchronous brain metabolic network in relation to the epileptic nondepressed group. SIGNIFICANCE: This study revealed relevant alterations in glucose metabolism and the metabolic network among the brain regions of interest for both epilepsy and depression pathologies. Thus it seems that depression in epileptic animals is associated with a more diffuse hypometabolism and altered metabolic network architecture and plays an important role in chronic epilepsy. PMID- 29600826 TI - "Leading Better Care": An evaluation of an accelerated coaching intervention for clinical nursing leadership development. AB - AIM: Outcomes of an accelerated co-active coaching intervention for senior clinical nursing leadership development. BACKGROUND: Co-active coaching is characterized by a whole person approach, commitment to deep learning and conscious action through supportive compassionate and courageous coach-coachee partnership. The national leadership capabilities framework, "Step into Leadership", was used for development and evaluation. METHODS: 116 senior clinical nurse leaders attended one face-to-face induction day and received a total of 3 hours of one-to-one telephone coaching and two virtual peer group facilitated sessions. Evaluation used primarily qualitative descriptive methods with iterative review of emerging themes. RESULTS: Capability mapping indicated self-leadership development as the most frequently cited need. Improvements in self-confidence, capacity for reflection and bringing whole self into the work were reported to deliver enhancement in team and service performance. CONCLUSIONS: Co-active coaching supported deep analysis by individuals. Focus on self, rather than behaviours provoked reflection on perspectives, mindsets, beliefs and approaches which can lead to more sustainable behaviour and support service change. IMPLICATIONS FOR NURSING MANAGEMENT: Investment in a co-active coaching approach offers bespoke support for clinical leaders to develop self leadership capability, a precursor to delivering positive impacts on care.

PMID- 29600828 TI - An electrical plasma dissection tool for surgical treatment of chronic ulcers: Results of a prospective randomised trial. AB - Cutaneous ulceration is a difficult medical problem and a major source of morbidity for patients. In the surgical treatment of ulcers, debridement is the first step, and it can be carried out using several surgical tools. Recently, new surgical devices have emerged using plasma-mediated electrical discharges with a lower peak temperature. A prospective single-blind trial was conducted on chronic ulcers not responsive to common non-surgical management. Patients were randomly separated into 2 groups: Group A received surgical debridement with conventional electrocautery, and Group B received surgical debridement using the plasma mediated device. Histological samples were collected intraoperatively to evaluate the thermal damage during the surgical procedure and 2 weeks after surgery to evaluate the inflammatory response and collagen deposition. The width of coagulation necrosis at the incision margins in Group B was significantly shorter compared with Group A (P = .001). The inflammatory cell infiltration showed a cellular distribution percentage that was quite equal between the 2 groups. The granulation tissue showed an abundant deposition of dense and mature collagen in Group B, compared with Group A, where the mature collagen appeared in small quantities (P < .001). Microbial culture showed a lower incidence of postoperative infections in Group B compared with the control group (P < .05). The study demonstrated, based on the results, that the new technology with the use of a lower temperature electrosurgical device represents an effective therapeutic weapon for the surgical treatment of skin ulcers, both vascular and extravascular types.

PMID- 29600830 TI - Evaluation of Kinase Inhibitor Selectivity Using Cell-based Profiling Data. AB - Kinases are among the most heavily investigated drug targets and inhibition of kinases and kinase-dependent signaling has become a paradigm for therapeutic intervention. Kinase inhibitors and associated activity data have increasing 'big data' character, which presents challenges for computational analysis, but also unprecedented opportunities for learning from compound data and for data-driven medicinal chemistry. Herein, publicly available kinase inhibitor data are evaluated and a number of characteristics are discussed. In addition, selectivity of clinical kinase inhibitors is explored computationally on the basis of recently reported cell-based profiling data. For inhibitors shared by pairs of kinases, selectivity profiles were generated and a variety of selective inhibitors were identified. Uni-directional selectivity profiles revealed inhibitors that were selective for one kinase over the other, while bi directional profiles uncovered compounds with inverted selectivity for paired kinases.

AB - The gram-scale synthesis, stabilization, and characterization of well-defined ultrasmall subnanometric catalytic clusters on solids is a challenge. The chemical synthesis and X-ray snapshots of Pt02 clusters, homogenously distributed and densely packaged within the channels of a metal-organic framework, is presented. This hybrid material catalyzes efficiently, and even more importantly from an economic and environmental viewpoint, at low temperature (25 to 140 degrees C), energetically costly industrial reactions in the gas phase such as HCN production, CO2 methanation, and alkene hydrogenations. These results open the way for the design of precisely defined catalytically active ultrasmall metal clusters in solids for technically easier, cheaper, and dramatically less dangerous industrial reactions.

AB - Bullous pemphigoid is the most common autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and presents with itch and localized or generalized bullous lesions. In up to 20% of affected patients blister may be completely absent, and only excoriations, prurigo-like lesions, eczematous lesions, urticated lesions, and/or infiltrated plaques are observed. The disease is significantly associated with neurological disorders. The morbidity of bullous pemphigoid and its impact on the quality of life are significant. So far, a limited number of national treatment guidelines have been proposed, but no common European consensus has emerged. This guideline for the treatment of bullous pemphigoid has been developed by an Italian group of experts taking in account the Italian legislation and local pharmacological governance. Guidelines are adapted from the original article under the guidance of the European Dermatology Forum (EDF) in collaboration with the European Academy of Dermatology and Venereology (EADV). It summarizes evidence-based and expert-based recommendations (S2 level). PMID- 29600835 TI - Ovarian preservation in locally advanced cervical cancer undergoing neoadjuvant chemotherapy and radical surgery. AB - BACKGROUND: The aim of this study was to estimate the rate of ovarian metastases and recurrences among patients affected by locally advanced stage cancer patients (LACC), undergoing neoadjuvant chemotherapy (NACT) and radical surgery with conservation of ovaries. METHODS: Retrospective evaluation of consecutive patients affected by LACC (stage IB2-IIB), treated by NACT followed by radical surgery at National Cancer Institute, Milan, Italy, between 1990-2015. RESULTS: Overall, 331 patients were included. Stage at presentation included stage IB2, IIA and IIB in 120 (36.3%), 63 (19%) and 148 (44.7%) patients, respectively. Main histotype was squamous cell carcinoma (N.=265, 80.1%) followed by adenocarcinoma/adenosquamous (N.=51, 15.4%), and more than half of patients had a grade 3 carcinoma. Overall, 102 (30.8%) women had at least one ovary preserved during surgery, while 229 (69.2%) had bilateral salpingo-oophorectomy. Comparing patients who had ovarian preservation with patients who had not, we observed that the two groups were comparable in terms of baseline characteristics. Survival outcomes were not influenced by ovarian preservation (disease-free [P=0.93] and overall [P=0.65] survivals). One (1%) woman had a localized ovarian recurrence. CONCLUSIONS: Our data suggest that ovarian preservation at the time of surgery is a safe option among women with LACC after NACT with no detrimental impact on oncologic outcome. Further prospective studies are warranted. PMID- 29600836 TI - Anorexia nervosa and alcohol use disorders: a change is necessary. PMID- 29600837 TI - The effects of functional and traditional strength training on different parameters of strength elderly women: a trial randomized and controlled. AB - BACKGROUND: Physical exercise is the main strategy for improving physical fitness in elderly population. However, it is not clear which training method lead to greater adaptations on maximal dynamic strength, muscle power, muscle endurance and isometric strength in this population. Thus, our aim was to compare the effects of functional and traditional training on these variables in the elderly. METHODS: This study lasted twelve weeks, where forty-four elderly women were randomly divided into three groups: Functional (FT; n = 18); Traditional (TT; n = 15); and Control (CG; n = 11). Maximal dynamic strength (Strength) and muscle power (Power) tests were performed in pushing (Push), pulling (Pull) and squatting (Squat) actions. In addition, isometric strength (ISO) with Hand Grip Test (HG) and Isometric Dead Lift Test (ID) and muscle endurance (Endurance) with 30 s chair stand (CS) and 30 s arm curl (AC) tests were used. RESULTS: Both experimental groups improved significantly in Strength (FT: Push 24.9%; Squat 38.4%; Pull 21.6% / TT: Push 18.2%; Squat 9.8%; Pull 19.2%), Power (FT: Push 13.6%; Squat 11.6%; Pull 13.6% / TT: Push 18.2%; Squat 9.8%; Pull 19.2%) ISO (FT: HG 14,7%; ID 13,6% / TT: HG 19,1%) and Endurance (TF: CS 19.6%; AC 23.8% / TT: CS 15.5%) with p <= 0,05, except TT in ID (4.4%) and SL (4.6%). There was no difference between experimental groups; however, both experimental groups were statistically superior to CG. CONCLUSIONS: Both training protocols were equally effective in improving different strength manifestations in the elderly.

The CO-releasing ability of vesicles appended with 1.Mn complexes has been confirmed by myoglobin assay and infrared study. The vesicles appended with 1.Mn have the advantages of biocompatibility, water solubility, and steady and slow CO release. This approach could be a rational approach for applying various water-insoluble photoinduced CO donors in aqueous media by using vesicles as a nanocarrier for CO release.

AB - Rechargeable lithium metal anodes (LMAs) with long cycling life have been regarded as the "Holy Grail" for high-energy-density lithium metal secondary batteries. The skeleton plays an important role in determining the performance of LMAs. Commercially available copper foam (CF) is not normally regarded as a suitable skeleton for stable lithium storage owing to its relatively inappropriate large pore size and relatively low specific surface area. Herein, for the first time, we revisit CF and address these issues by rationally designing a highly porous copper (HPC) architecture grown on CF substrates (HPC/CF) as a three-dimensional (3D) hierarchically bicontinuous porous skeleton through a novel approach combining the self-assembly of polystyrene microspheres, electrodeposition of copper, and a thermal annealing treatment. Compared to the CF skeleton, the HPC/CF skeleton exhibits a significantly improved Li plating/stripping behavior with high Coulombic efficiency (CE) and superior Li dendrite growth suppression. The 3D HPC/CF-based LMAs can run for 620 h without short-circuiting in a symmetric Li/Li@Cu cell at 0.5 mA cm-2, and the Li@Cu/LiFePO4 full cell exhibits a high reversible capacity of 115 mAh g-1 with a high CE of 99.7% at 2 C for 500 cycles. These results demonstrate the effectiveness of the design strategy of 3D hierarchically bicontinuous porous skeletons for developing stable and safe LMAs.

AB - The cell membranes of all archaea contain ether lipids, and a number of archaea are hyperthermophilic. Consequently, the enzymes that catalyze the synthesis of membrane ether lipids had to adopt to these rough conditions. Interestingly, the enzyme that establishes the first ether bond in these lipids, the geranylgeranylglyceryl phosphate synthase (GGGPS), forms hexamers in many hyperthermophilic archaea, while also dimeric variants of this enzyme exist in other species. We used Methanothermobacter thermautotrophicus GGGPS (mtGGGPS) as a model to elucidate the benefit of hexamerization. We studied the oligomerization interfaces in detail by introducing disturbing mutations and subsequently compared the stability and activity of generated dimeric and monomeric variants with the wild-type enzyme. Differential scanning calorimetry revealed a biphasic denaturation of mtGGGPS. The temperature of the first transition varies and rises with increasing oligomerization state. This first phase of denaturation leads to catalytic inactivation, but CD spectroscopy indicated only minor changes on the secondary structure level. The residual part of the fold is extremely thermostable and denatures in a second phase at temperatures >120 degrees C. The analysis of another distant native GGGPS enzyme affirms these observations. Molecular dynamics simulations revealed three structural elements close to the substrate binding sites with elevated flexibility. We assume that hexamerization might stabilize these structures, and kinetic studies support this hypothesis for the binding pocket of the substrate glycerol 1-phosphate. Oligomerization might thus positively affect the thermostability-flexibility trade-off in GGGPS by allowing a higher intrinsic flexibility of the individual protomers. PMID- 29600843 TI - Entanglement-Based Thermoplastic Shape Memory Polymeric Particles with Photothermal Actuation for Biomedical Applications. AB - Triggering shape-memory functionality under clinical hyperthermia temperatures could enable the control and actuation of shape-memory systems in clinical practice. For this purpose, we developed light-inducible shape-memory microparticles composed of a poly(d,l-lactic acid) (PDLLA) matrix encapsulating gold nanoparticles (Au@PDLLA hybrid microparticles). This shape-memory polymeric system for the first time demonstrates the capability of maintaining an anisotropic shape at body temperature with triggered shape-memory effect back to a spherical shape at a narrow temperature range above body temperature with a proper shape recovery speed (37 < T < 45 degrees C). We applied a modified film stretching processing method with carefully controlled stretching temperature to enable shape memory and anisotropy in these micron-sized particles. Accordingly, we achieved purely entanglement-based shape-memory response without chemical cross-links in the miniaturized shape-memory system. Furthermore, these shape memory microparticles exhibited light-induced spatiotemporal control of their shape recovery using a laser to trigger the photothermal heating of doped gold nanoparticles. This shape-memory system is composed of biocompatible components and exhibits spatiotemporal controllability of its properties, demonstrating a potential for various biomedical applications, such as tuning macrophage phagocytosis as demonstrated in this study. PMID- 29600844 TI - Click Chemical Ligation-Initiated On-Bead DNA Polymerization for the Sensitive Flow Cytometric Detection of 3'-Terminal 2'-O-Methylated Plant MicroRNA. AB - A versatile flow cytometric strategy is developed for the sensitive detection of plant microRNA (miRNA) by coupling the target-templated click nucleic acid ligation (CNAL) with on-bead terminal enzymatic DNA polymerization (TEP). Unlike ligase-catalyzed ligation reaction, the plant miRNA-templated enzyme-free CNAL between two single-stranded DNA (ssDNA) probes, respectively modified with Aza dibenzocyclooctyne (Aza-DBCO) and N3, can not only simplify the operation, but also achieve a much higher ligation efficiency. More importantly, the undesirable nonspecific ligation between the Aza-DBCO- and N3-modified ssDNA, can be effectively eliminated by adding Tween-20, which allows the use of cycling CNAL (CCNAL) in a background-free manner. So each plant miRNA can template many rounds of CNAL reaction to produce numerous ligation products, forming efficient signal amplification. The ligated ssDNA can be anchored on the magnetic beads (MBs) with the 3'-OH termini exposed outside. Then terminal deoxynucleotidyl transferase (TdT), a sequence-independent and template-free polymerase, would specifically catalyze the DNA polymerization along these 3'-OH termini on the MBs, forming poly(T) tails up to thousands of nucleotides long. Each poly(T) tail allows specific binding of numerous 6-carboxyfluorescein (FAM)-labeled poly(A)25 oligonucleotides to accumulate a lot of fluorophores on the MBs, leading to the second step of signal amplification. By integrating the advantages of CCNAL-TEP for highly efficient signal amplification and robust MBs signal readout with powerful flow cytometer, high sensitivity is achieved and the detection limit of plant miRNA has been pushed down to a low level of 5 fM with high specificity to well discriminate even single-base difference between miRNA targets.

AB - Delamination treatment is crucial in promoting the activity of bulk graphitic carbon nitride (g-C3N4). However, most of the currently used methods of exfoliating bulk g-C3N4 to achieve g-C3N4 thin layers suffer from low yield and environmental pollution. Herein, we developed a facile bacterial etching approach for the preparation of high-quality g-C3N4 nanosheets by exfoliating bulk g-C3N4 under room temperature. Morphology and physicochemical characterizations show that the bacteria-treated g-C3N4 (BT-CN) samples, especially BT-CN-2d, have a lamina-like two-dimensional (2D) in-plane porous structure, a significantly enlarged specific surface area (82.61 m2 g-1), and a remarkable narrow band gap (2.11 eV). X-ray photoelectron spectroscopy and electron paramagnetic resonance spectra confirm the dramatic enrichment of unpaired electron in the BT-CN-2d g C3N4 nanosheets. EIS spectra and photocurrent tests indicate the fast electron transportation. As a result, the representative BT-CN-2d g-C3N4 photocatalyst shows an optimal visible light-driven photocatalytic performance in water disinfection (fourfold higher than bulk g-C3N4), as well as good cycle stability. This moderate and clean bacterial etching process can be realized in tens of gram scale in the laboratory and should be readily extended to kilogram scale. The present work provides fundamental knowledge about the scalable production of high quality g-C3N4 by bioengineering method, offering extendable availability for designing and fabricating other functional 2D materials.

AB - The stability issue of organometallic halide perovskites remains a great challenge for future research as to their applicability in different functional material fields. Herein, a novel and facile two-step synthesis procedure is reported for encapsulation of CH3NH3PbBr3 perovskite quantum dots (QDs) in MOF-5 microcrystals, where PbBr2 and CH3NH3Br precursors are added stepwise to fabricate stable CH3NH3PbBr3@MOF-5 composites. In comparison to CH3NH3PbBr3 QDs, CH3NH3PbBr3@MOF-5 composites exhibited highly improved water resistance and thermal stability, as well as better pH adaptability over a wide range. Luminescent investigations demonstrate that CH3NH3PbBr3@MOF-5 composites not only featured excellent sensing properties with respect to temperature changes from 30 to 230 degrees C but also exhibited significant selective luminescent response to several different metal ions in aqueous solution. These outstanding characteristics indicate that the stable CH3NH3PbBr3@MOF-5 composites are potentially interesting for application in fluorescence sensors or detectors.

AB - Three novel polyketide-like metabolites, trichorenins A-C (1-3), with a unique tetracyclic carbon skeleton were obtained from the culture of Trichoderma virens Y13-3, an epiphyte of the marine red alga Gracilaria vermiculophylla. Their structures and relative configurations were established by analysis of 1D/2D NMR and MS data, and their absolute configurations were unequivocally assigned by X ray diffraction and ECD spectra aided by quantum chemical calculations. Compounds 1-3 exhibited potent inhibition against two marine phytoplankton species, Chattonella marina and Karlodinium veneficum. PMID- 29600849 TI - Isomerization Reaction of mer- to fac-Tris(2-phenylpyridinato-N,C2')Iridium(III) Monitored by Using Surface-Enhanced Raman Spectroscopy. AB - We developed a new method by enclosing the complex tris(2-phenylpyridinato N,C2')Iridium(III), Ir(ppy)3 with surfactant cetyltrimethylammonium bromide (CATB), coated with a thin layer of silica then bonded to the surface of silver nanoparticle. These samples were used to acquire surface-enhanced Raman scattering (SERS) spectra. The thickness of silica layer was controlled to have efficient phosphorescence quenching and Raman enhancement by metal nanoparticle. The SERS spectra of fac- and mer-Ir(ppy)3, recorded at 633 nm excitation, display distinct ring breathing mode features because the total symmetric vibrational bands were enhanced. This provides a convenient means to differentiate these isomers with great sensitivity and to study their isomerization process. A direct conversion reaction of mer- to fac- isomerization is identified with time constant 3.1 min when mer was irradiated with Xe light. Via thermal activation, under moderate conditions (pH 5.5 and 343 K), we observed an intermediate particularly with new bands 320/662 cm-1 after heating for 17.5 h, and then those bands disappeared to form fac-Ir(ppy)3. On the basis of DFT calculations, the intermediate is proposed to contain octahedral N-N Ir(ppy)3-HO-silica structure; band at 320 cm-1 is assigned to iridium oxygen stretching mode nuIr-O of this intermediate. Under acidic conditions, pH 1-2 catalyzed by silanol in silica, byproduct with band at 353 cm-1 was observed. According to the SERS bands and the calculation, this byproduct is assigned to be iridium(III) siloxide, and the new band is assigned to nuIr-O.

AB - We present an algorithm, ReFlex3D, for the refinement of flexible molecular alignments based on their three-dimensional shape and electrostatic properties. The algorithm is designed to be used with fast conformer generators to refine an initial overlay between two molecules and thus to obtain improved overlaps as judged by an increase in calculated similarity values. ReFlex3D is open-source and built as a python package working in combination with the OEChem Toolkit. As such it can readily be implemented in existing workflows ranging from the selection of compounds from a virtual screening campaign to the construction of similarity based prediction models to estimate binding affinities. We evaluate ReFlex3D against the AstraZeneca Validation Test Set and illustrate its potential within a predictive model compared to an established method (Posit). PMID- 29600851 TI - Octahedral-Tetrahedral Systems [Co( dppm O, O)3]2+[CoX4]2- Showing Slow Magnetic Relaxation with Two Relaxation Modes. AB - Three compounds with octahedral-tetrahedral Co(II) moieties of [Co( dppm O, O)3][CoX4] type, where X = SCN (1), Cl (2), or I (4) have been synthesized and characterized by the X-ray structure analysis (1 and 4), and spectroscopic methods. The dc magnetic measurements show high magnetic anisotropy for octahedral centers whereas tetrahedral sites possess moderate D values. These results are confirmed by the ab initio calculations. The ac susceptibility data reveals a slow magnetic relaxation for 2 and 4, similar to that of the X = Br analogue (3), whereas 1 displays no ac-absorption signal. There are two relaxation channels; the slower for 2 (4) possesses a relaxation time as long as tauLF= 178 (588) ms at T = 1.9 K and Bdc = 0.7 T. Also, the half-Zn analogue, [Co( dppm O, O)3][ZnI4], shows slow magnetic relaxation with two relaxation channels conditioned by the cationic unit [Co( dppm O, O)3]2+.

AB - A novel and efficient protocol for the construction of trifluoroethyl pyrazolines has been developed by cascade cyclization/trifluoromethylation reaction of beta,gamma-unsaturated hydrazones. This strategy uses cheap and commercially available trichloroisocyanuric acid as promoter and TMSCF3 as the trifluoromethylating reagent, which make the trifluoromethylating process much cheaper. A wide range of substrates can be applied in this process to afford the trifluoroethyl pyrazolines in good yield.

These chains are connected to each other and delimit tunnels in the [221], [221], and [001] directions, in which NH4+ cations are located. Mossbauer spectroscopy confirms the presence of FeII and FeIII. The title compound is the first example of a mixed-valence ammonium iron phosphate. PMID- 29600855 TI - Rational Engineering of Multiple Active Sites in an Ester Hydrolase. AB - Effects of altering the properties of an active site in an enzymatic homogeneous catalyst have been extensively reported. However, the possibility of increasing the number of such sites, as commonly done in heterogeneous catalytic materials, remains unexplored, particularly because those have to accommodate appropriate residues in specific configurations. This possibility was investigated by using a serine ester hydrolase as the target enzyme. By using the Protein Energy Landscape Exploration software, which maps ligand diffusion and binding, we found a potential binding pocket capable of holding an extra catalytic triad and oxyanion hole contacts. By introducing two mutations, this binding pocket became a catalytic site. Its substrate specificity, substrate preference, and catalytic activity were different from those of the native site of the wild type ester hydrolase and other hydrolases, due to the differences in the active site architecture. Converting the binding pocket into an extra catalytic active site was proven to be a successful approach to create a serine ester hydrolase with two functional reactive groups. Our results illustrate the accuracy and predictive nature of modern modeling techniques, opening novel catalytic opportunities coming from the presence of different catalytic environments in single enzymes. PMID- 29600856 TI - Mechanism of Water Oxidation Catalyzed by a Mononuclear Iron Complex with a Square Polypyridine Ligand: A DFT Study. AB - The mononuclear [Cl-FeIII(dpa)-Cl]+ (1Cl) complex containing a square planar tetradentate polypyridine ligand has been reported to catalyze water oxidation in pH = 1 aqueous medium with ceric ammonium nitrate (CAN) as a chemical oxidant. The reaction mechanism of the oxygen evolution driven by this catalyst was investigated by means of density functional calculations. The results showed that one chloride ligand of 1Cl has to exchange with a water molecule to generate 1, [Cl-FeIII(dpa)-OH2]2+, as the starting species of the catalytic cycle. The initial one-electron oxidation of 1 is coupled with the release of two protons, generating [Cl-FeIV(dpa)?O]+ (2). Another one-electron transfer from 2 leads to the formation of an FeV?O complex [Cl-FeV(dpa)?O]2+ (3), which triggers the critical O-O bond formation. The electronic structure of 3 was found to be very similar to that of the high-valent heme-iron center of P450 enzymes, termed Compound I, in which a pi-cation radical ligand is believed to support a formal iron(IV)-oxo core. More importantly, 3 and Compound I share the same tendency toward electrophilic reactions. Two competing pathways were suggested for the O-O bond formation based on the present calculations. One is the nitrate nucleophilic attack on the iron(V)-oxo moiety with a total barrier of 12.3 kcal mol-1. In this case, nitrate functions as a co-catalyst for the dioxygen formation. The other is the water nucleophilic attack on iron(V)-oxo with a greater barrier of 16.5 kcal mol-1. In addition, ligand degradation via methyl hydrogen abstraction was found to have a barrier similar to that of the O-O bond formation, while the aromatic carbon hydroxylation has a higher barrier. PMID- 29600857 TI - From "Cellular" RNA to "Smart" RNA: Multiple Roles of RNA in Genome Stability and Beyond. AB - Coding for proteins has been considered the main function of RNA since the "central dogma" of biology was proposed. The discovery of noncoding transcripts shed light on additional roles of RNA, ranging from the support of polypeptide synthesis, to the assembly of subnuclear structures, to gene expression modulation. Cellular RNA has therefore been recognized as a central player in often unanticipated biological processes, including genomic stability. This ever expanding list of functions inspired us to think of RNA as a "smart" phone, which has replaced the older obsolete "cellular" phone. In this review, we summarize the last two decades of advances in research on the interface between RNA biology and genome stability. We start with an account of the emergence of noncoding RNA, and then we discuss the involvement of RNA in DNA damage signaling and repair, telomere maintenance, and genomic rearrangements. We continue with the depiction of single-molecule RNA detection techniques, and we conclude by illustrating the possibilities of RNA modulation in hopes of creating or improving new therapies. The widespread biological functions of RNA have made this molecule a reoccurring theme in basic and translational research, warranting it the transcendence from classically studied "cellular" RNA to "smart" RNA. PMID- 29600858 TI - Imaging the Dynamics of CH2BrI Photodissociation in the Near Ultraviolet Region. AB - The photodissociation dynamics of jet-cooled CH2BrI were investigated in the near ultraviolet (UV) region from 280-310 nm using velocity map imaging. We report the translational and internal energy distributions of the CH2Br radical and ground state I (2 P3/2) or spin-orbit excited I (2 P1/2) fragments determined by velocity map imaging of the ionized iodine fragments following 2 + 1 resonance enhanced multiphoton ionization of the nascent neutral iodine products. The velocity distributions indicate that most of the available energy is partitioned into the internal energy of the CH2Br radical with only modest translational excitation imparted to the cofragments, which is consistent with a simple impulsive model. Furthermore, from extrapolation of the velocity distribution results, the first determination of the C-I bond dissociation energy of CH2BrI is presented in this work to be D0 = 16 790 +/- 590 cm-1. The ion images appear anisotropic, indicative of a prompt dissociation, and the derived anisotropy parameters are consistently positive. Additionally, the angular distributions report on the electronic excited state dynamics, which validate recent works characterizing the electronic states responsible for the first absorption band of CH2BrI. In the current work, photolysis of CH2BrI on the red edge of the absorption spectrum reveals an additional channel producing I (2 P3/2) fragments.

AB - Olefin cross metathesis is reported for the first time to attach small molecules to a range of novel polyethers with a poly(ethylene glycol) backbone and pendent alkene groups, allowing for a loading of up to one compound per monomer unit. These polymers are tailored to prevent the occurrence of self metathesis (reaction of the polymer with itself) by varying the substitution on the pendent alkenes, thus steering their reactivity toward olefin cross metathesis. Efficient functionalization has been observed for a range of coupling partners as a proof of concept for the use of olefin metathesis to graft small and larger molecules to polyethers for drug delivery. This approach also paves the way for the use of olefin cross metathesis as an efficient method to functionalize a wide variety of polymers with pendent olefin groups.

Due to the evolution of adhesive materials and ceramics, minimalistic ceramic restorations have been proposed as alternative treatment options to avoid unnecessary tooth reduction. The aim of this article is to show a clinical protocol for the correct diagnosis, treatment planning, and execution of minimally invasive ceramic veneers. Requiring only slight tooth preparation, this conservative technique is well-suited for restoration of teeth that need color and shape modification. The present clinical case demonstrates immediate success in restoring patient esthetics, function, and, in turn, self-esteem. After 2.5 years all veneers were still in exceptional condition and periodontal tissue was healthy. Minimally invasive ceramic restoration is shown to be an excellent option for conservative restorative treatment.

AB - OBJECTIVE: This study evaluated intracanal smear layer removal using syringe and needle irrigation (ie, conventional irrigation [CI]) with and without adjunctive activation using EndoActivator(r) or EndoUltra(r). MATERIALS AND METHODS: Thirty five premolars were divided into three experimental groups (n = 10) and a control (n = 5): (1) CI, (2) CI plus sonic activation (EndoActivator), (3) CI plus ultrasonic activation (EndoUltra), or (4) CI using saline. All teeth were prepared to a size #40 K file. Following irrigation, the teeth were split and imaged using scanning electron microscopy (SEM). SEM images were evaluated by: (1) blinded researchers who provided a smear layer score (1-5), and (2) a custom software algorithm that automatically and independently quantified the number of open tubules. RESULTS: Use of both the EndoActivator and EndoUltra resulted in significantly cleaner smear layer scores at all canal thirds compared to CI (P < .001). The EndoUltra yielded significantly cleaner scores than the EndoActivator at the apical third (P < .001); however, no significant difference was evident in the middle and coronal thirds. The software analysis yielded the same conclusions as the smear layer scores except statistical significance was seen between the EndoUltra and EndoActivator at all canal thirds (P < .02). Of the adjunctive irrigant activators, the EndoUltra opened 94%, 117%, and 26% more tubules in the apex, middle, and coronal thirds, respectively, than the EndoActivator. CONCLUSIONS: The EndoUltra cleaned canals more effectively than the EndoActivator and CI. PMID- 29600869 TI - Periodontal Tissue Bioengineering: Is the Future Now?

PMID- 29600870 TI - Integrating Caries Management by Risk Assessment (CAMBRA) and Prevention Strategies Into the Contemporary Dental Practice. AB - In the past, the dental profession has adhered to a rigid tenet: remove decay from a tooth and then restore, a mindset that has been proverbially dubbed as "drill and fill." Today, dental caries is recognized as an infectious disease that affects children and adults throughout life. The philosophy of CAries Management By Risk Assessment, or CAMBRA(r), represents a paradigm shift. The CAMBRA concept provides the dentist with scientific, evidence-based solutions with which to approach treatment of dental caries disease. This article reviews the current understanding of the caries balance, the process of demineralization and remineralization of tooth structure, caries risk assessment, and the different levels of caries risk. Adequate treatment protocols specifically related to the remineralization of non-cavitated lesions and CAMBRA validation studies are discussed.

AB - Delusional infestations are psychodermatologic disorders in which those affected have a false belief they are infested by parasites and/or "growing" inanimate objects from cutaneous surfaces. Individuals with delusional parasitosis (DP) believe parasites, bacteria, worms, mites, or other living organisms are the source of cutaneous symptoms, while those with Morgellons disease (MD) attribute their symptoms to growth of small fibers or inorganic material. In both DP and MD, self-inflicted, non-healing cutaneous lesions caused by scratching at the affected areas to alleviate symptoms are commonly observed. This report describes a case of oral mucosal lesions in a patient demonstrating overlapping symptoms of DP and MD. It is important for oral healthcare providers to recognize oral signs and symptoms that may be associated with psychodermatologic disorders. PMID- 29600873 TI - Long-Term Esthetic and Functional Success Following an Initial Treatment Complication. AB - This case describes the successful long-term outcome of a patient's treatment after a restorative failure occurred soon after delivery. The esthetic and restorative treatment has been successful for nearly a decade due largely to a careful, objective evaluation of all possible causes of the restorative failure. The treatment plan for the patient, who was assessed as high risk biomechanically and functionally, was carried out in the following phases: (1) an implant placement that required an osteotome sinus lift; (2) placement of feldspathic bonded veneers for the maxillary anterior teeth to minimize removal of tooth structure; (3) numerous core-supported restorations, with fixed partial dentures placed for teeth Nos. 19 through 21 and 28 through 30; and (4) the use of a Kois deprogrammerTM to determine condylar position/centric relation reference. Finally, the maxillary teeth were lengthened to create a pleasing smile and the vertical dimension increased and restored in centric relation.

AB - Swimming is a non-weight bearing form of exercise that can be enjoyable and promote physical fitness. This qualitative study investigated a local group established as part of a national dementia swimming initiative. Semi-structured interviews with people with dementia (N = 4), carers or companions (N = 4) and the organisers and facilitators of the group (N = 6) were analysed using thematic analysis. This revealed four main themes: (1) the pleasure of swimming and its benefits as a form of exercise and for building confidence and empowering participants, (2) the importance of insight and empathy in creating a safe and secure experience, (3) the impact of dementia and (4) how participants valued being part of a group 'all in the same boat'. 'Dementia friendly swimming' appears to be a valuable form of exercise, but it requires considerable preparation and support to make it happen.

AB - The lower cloud layer of Venus (47.5-50.5 km) is an exceptional target for exploration due to the favorable conditions for microbial life, including moderate temperatures and pressures (~60 degrees C and 1 atm), and the presence of micron-sized sulfuric acid aerosols. Nearly a century after the ultraviolet (UV) contrasts of Venus' cloud layer were discovered with Earth-based photographs, the substances and mechanisms responsible for the changes in Venus' contrasts and albedo are still unknown. While current models include sulfur dioxide and iron chloride as the UV absorbers, the temporal and spatial changes in contrasts, and albedo, between 330 and 500 nm, remain to be fully explained. Within this context, we present a discussion regarding the potential for microorganisms to survive in Venus' lower clouds and contribute to the observed bulk spectra. In this article, we provide an overview of relevant Venus observations, compare the spectral and physical properties of Venus' clouds to terrestrial biological materials, review the potential for an iron- and sulfur centered metabolism in the clouds, discuss conceivable mechanisms of transport from the surface toward a more habitable zone in the clouds, and identify spectral and biological experiments that could measure the habitability of Venus' clouds and terrestrial analogues. Together, our lines of reasoning suggest that particles in Venus' lower clouds contain sufficient mass balance to harbor microorganisms, water, and solutes, and potentially sufficient biomass to be detected by optical methods. As such, the comparisons presented in this article warrant further investigations into the prospect of biosignatures in Venus' clouds.

AB - This study was undertaken to evaluate the feasibility of using commercial starter cultures for quality improvement of spreadable processed cheese manufactured from ultrafiltered milk retentates. Compared to control, six samples of ultrafiltered milk retentate were incubated at 25 C with starter cultures CHN-22, FRC-60, and ABT-8. Three samples were incubated for 24 h and the others were incubated for 72 h. Physicochemical, microbiological, and organoleptic characteristics in all treatments during the 90-day cold storage (6 +/- 2 C) period were determined. The results showed that protein content of all treatments was significantly lower than the control. Utilization of starter cultures in ultrafiltered processed cheese production increased titratable acidity, where titratable acidity of the treatments (PC22-3, PC60-3, and PC8-3) was significantly higher than the other treatments and the control. PC8-1, PC60-1, and PC22-1 treatments were the highest penetrometer readings and with low firmness. All treatments had higher water soluble nitrogen/total nitrogen%, total bacterial viable and lactic acid bacterial counts especially PC22-3, PC60-3, and PC8-3 compared to the control. The results revealed that PC60-1 and PC22-3 treatments gained the highest acceptability scores than PC60-3, PC22-1, and the control. PMID- 29600877 TI - Interference Assessment of Various Endogenous and Exogenous Substances on the Performance of the Eversense Long-Term Implantable Continuous Glucose Monitoring System. AB - BACKGROUND: A variety of prescriptions and over-the-counter medications interfere with transcutaneous continuous glucose monitoring (CGM) sensors. This study characterized the interference profile of the Eversense(r) CGM System (Senseonics, Inc., Germantown, MD), which has a different mechanism of glucose detection than other CGM systems. MATERIALS AND METHODS: Sensor bias (sensor glucose concentration measurement - plasma glucose concentration measured by a reference test) was measured in vitro against 41 different substances at supratherapeutic/supraphysiologic plasma concentrations. Testing was performed using a paired-sample method adapted from the Clinical and Laboratory Standards Institute guidance document EP7-A2. Any substance producing sensor bias that exceeded the International Organization for Standardization (ISO) document 15197:2013 limits was then tested using an in vitro dose-response method to determine whether the concentration producing a significant sensor bias was within physiologic/therapeutic concentration ranges. RESULTS: Eight of 41 substances produced a sensor bias that exceeded ISO 15197:2013 limits when tested in vitro at supratherapeutic/supraphysiologic plasma concentrations. Only two of these substances (tetracycline and mannitol) exceeded bias limits within therapeutic concentration ranges. Notably, neither acetaminophen nor ascorbic acid, which are substances reported to interfere with other CGM systems, produced sensor bias that exceeded ISO limits when used at physiologic concentrations. CONCLUSIONS: Although tetracycline and mannitol interfered with the Eversense sensor, substances frequently reported to interfere with enzymatic, electrochemical-based transcutaneous CGM systems, such as acetaminophen and ascorbic acid, did not affect Eversense readings.

AB - This study investigated the influence of pregelatinized high-amylose maize starch and chilling treatment on the physical and textural properties of canned rice noodles thermally processed in a retort. Rice noodles were prepared from rice flour partially substituted with pregelatinized high-amylose maize starch (Hylon VIITM) in the ratios 0, 5, 10, and 15% (wt/wt). High-amylose maize starch improved the texture and brightness of fresh (not retorted) noodles. Chilling treatment led to significant (P <= 0.05) improvement in the texture of fresh noodles at all levels of substitution with high-amylose starch. The highest hardness was recorded at 15% amylose level in chilled nonretorted noodles. Retort processing induced a major loss of quality through water absorption, retort cooking loss, decreased noodle hardness, and lightness. However, the results showed that amylose and chilling treatment positively reduced the impact of retorting. For each level of amylose substitution, a low retort cooking loss and increased noodle hardness were associated with a chilling treatment. For both chilled and nonchilled noodles, retort cooking loss and hardness increased with increasing levels of amylose substitution. PMID- 29600880 TI - Pharmacotherapeutic strategies for treating hypertension in patients with obesity. AB - INTRODUCTION: Hypertension and obesity are important health challenges that independently increase cardiovascular morbidity and mortality. There is a lack of randomized controlled trials to clearly inform on preferred drug choices to be adopted in clinical practice for the treatment of obesity-related hypertension (OHT). Adequate differentiation of drug classes for preferential use in obesity or the metabolic syndrome aimed at avoiding adverse effects on body weight and the metabolic profile is neglected in this population, at least in part due to the lack of specific pharmacologic recommendations in hypertension guidelines. Areas covered: The authors summarize and suggest pharmacotherapeutic strategies based on pathophysiologic rationale to achieve blood pressure (BP) control and avoid adverse metabolic consequences in OHT. Expert opinion: Combinations of various pharmacologic antihypertensive approaches are required in the management of OHT. It is recommended that targeting sympathetic overactivity with a centrally acting sympatholytic agent such as moxonidine should be considered as a preferred second line treatment choice in combination with renin angiotensin system (RAS) blockade, the current first line choice. Though not all obese subjects have sympathetic overdrive, this approach is likely to provide effective control of blood pressure and improve the metabolic profile of patients with OHT along with positive implications for cardiovascular risk reduction. PMID- 29600881 TI - Mental health consequences of weight cycling in the first-year post-treatment for breast cancer. AB - OBJECTIVES: Weight cycling is linked with advanced breast cancer diagnosis, increased risk of cancer reoccurrence and cancer-related mortality. While women treated for breast cancer report challenges with navigating their post-treatment body shape and weight, the effects of weight cycling on body image and mental health have not been elucidated. This study examined associations between weight changes and weight cycling on psychological health (i.e. weight-related guilt, shame and depressive symptoms) among women in the first-year post-treatment. DESIGN AND OUTCOME MEASURES: Self-reported assessments of pre-cancer weight cycling, post-treatment weight-related guilt, shame and depressive symptoms, and objective assessments of weight were assessed in a longitudinal sample of 173 women treated for breast cancer (Mage = 55.01 +/- 10.96 years). RESULTS: Based on findings from multilevel models, women experienced the most weight-related shame when their weight was heavier than their personal average. Additionally, heavier weight was associated with worse psychological health, particularly for women with a history of stable (vs. cycling) weight pre-cancer. CONCLUSIONS: Weight cycling pre-cancer and post-treatment weight change have important implications for psychological well-being. Due to the potential psychological consequences associated with a history of weight cycling, targeted strategies are needed to improve overall health outcomes for women's survivorship after breast cancer. PMID- 29600882 TI - Time to diagnosis in esophageal cancer: a cohort study. AB - BACKGROUND: The association between shorter time to diagnosis and favorable outcome is still unproven in esophageal cancer. This study aims to evaluate the effect of time to diagnosis on patient prognosis. MATERIAL AND METHODS: Retrospective cohort study of all 3613 symptomatic patients referred for esophageal cancer to our center from 1980 to 2011. Time to diagnosis was calculated as the number of days from first symptom onset to the diagnosis of esophageal cancer. The main outcome measures were: resectability and severe malnutrition at diagnosis; postoperative morbidity, mortality and survival. RESULTS: Longer time to diagnosis was significantly associated with severe malnutrition at diagnosis (odds ratio (OR): 1.003, 95% confidence interval (C.I.).: 1.001-1.006) but not with resectability (OR: 0.997, 95% C.I.: 0.994 1.001). Longer time to diagnosis was not associated with postoperative morbidity (OR: 1.000, 95% C.I.: 0.998-1.003), postoperative mortality (OR: 1.002, 95% C.I.: 0.998-1.006), five-year overall survival (hazard ratio (HR): 0.999, 95% C.I.: 0.997-1.001) or five-year disease free survival (HR: 0.999, 95% C.I.: 0.998 1.001). CONCLUSION: Longer time to diagnosis did not affect resectability, postoperative morbidity or survival. Further campaigns to raise awareness of cancer among population and primary health care providers may have limited effect on clinical outcome. PMID- 29600883 TI - Investigational drugs for vasospasm after subarachnoid hemorrhage. AB - INTRODUCTION: Aneurysmal subarachnoid hemorrhage (aSAH) represents 3% of all strokes in the US. When the patient survives it can lead to permanent incapacity especially if the patient develops vasospasm. The vasospasm is a multifactorial disorder and can lead to delayed cerebral ischemia (DCI). Most of the drugs tested to treat vasospasm failed to improve outcome and the only exception is nimodipine. Areas covered: In this review, the authors describe the multifactorial process of vasospasm leading DCI after aSAH, discussing the treatments available based on the past and latest researches. Expert opinion: Nimodipine is the only FDA-approved medication with neuroprotective effect and able to improve outcomes after aSAH. Understanding nimodipine trials is mandatory to understand and criticize all the drug trials published until now. The mechanism to vasospasm is multifactorial and not completely understood and all the other attempts to find a better medication could not prove superior results. Newton and PEGylated Carboxyhemoglobin Bovine can be potentially effective to prevent vasospasm but we still need more data and large studies. Future research should investigate newer drugs, as well as the combination of multiple drugs therapy and the association with blood evacuation techniques. PMID- 29600884 TI - Surgical decompression for recurrent cord compression in cancer: a case series and review of the literature. AB - Spine metastases affect a significant number of cancer patients each year, with the spine being the third most common location for cancer spread. As patients live longer with improved treatments, the opportunity for recurrence at previously treated sites increases. Here, we describe seven patients with recurrent, compressive, metastatic spine tumors at previously surgically treated sites that required additional surgical intervention with manipulation of at least one rod. Five of the patients had recurrence including adjacent levels while two had recurrence solely at the previously decompressed level. The patients remained ambulatory for an average of 31.2 months after the initial surgery. We also discuss the role of adjuvant treatment in these patients and review the literature. PMID- 29600885 TI - Titanium dioxide nanoparticle exposure alters metabolic homeostasis in a cell culture model of the intestinal epithelium and Drosophila melanogaster. AB - Nanosized titanium dioxide (TiO2) is a common additive in food and cosmetic products. The goal of this study was to investigate if TiO2 nanoparticles affect intestinal epithelial tissues, normal intestinal function, or metabolic homeostasis using in vitro and in vivo methods. An in vitro model of intestinal epithelial tissue was created by seeding co-cultures of Caco-2 and HT29-MTX cells on a Transwell permeable support. These experiments were repeated with monolayers that had been cultured with the beneficial commensal bacteria Lactobacillus rhamnosus GG (L. rhamnosus). Glucose uptake and transport in the presence of TiO2 nanoparticles was assessed using fluorescent glucose analog 2-(N-(7-nitrobenz-2 oxa-1,3-diazol-4-yl)amino)-2-deoxyglucose (2-NBDG). When the cell monolayers were exposed to physiologically relevant doses of TiO2, a statistically significant reduction in glucose transport was observed. These differences in glucose absorption were eliminated in the presence of beneficial bacteria. The decrease in glucose absorption was caused by damage to intestinal microvilli, which decreased the surface area available for absorption. Damage to microvilli was ameliorated in the presence of L. rhamnosus. Complimentary studies in Drosophila melanogaster showed that TiO2 ingestion resulted in decreased body size and glucose content. The results suggest that TiO2 nanoparticles alter glucose transport across the intestinal epithelium, and that TiO2 nanoparticle ingestion may have physiological consequences. PMID- 29600886 TI - Updated incidence trends in cardia and non-cardia gastric adenocarcinoma in Sweden. AB - BACKGROUND: The aim of this study was to provide an update of the recent incidence trends of cardia and non-cardia gastric adenocarcinoma in Sweden. METHODS: Temporal trends in the age-standardised incidence were assessed separately for cardia and non-cardia gastric adenocarcinoma in 1970-2014 among all people in Sweden aged >=50 years. Data were retrieved from the Swedish Cancer Registry. The log-linear joinpoint regression method was used to identify change points in the incidence trends. The annual percent changes with 95% confidence intervals (CI) were calculated for each segment before and after change points. RESULTS: The overall incidence of cardia adenocarcinoma increased during the earlier period of 1970-1988, but was stable during the later period of 1989-2014 (annual percent change: -0.3%, 95% CI: -0.7 to 0.2%). In contrast, in women aged 50-69 years the incidence of cardia adenocarcinoma increased by 6.6% annually (95% CI: 1.9 to 11.5%) during the period 2005 to 2014. The incidence of non cardia gastric adenocarcinoma decreased by 4.4% per year (95% CI: -4.6 to -4.2%) in 1984-2014 and the decrease was stronger in men aged 70 years or older compared to other groups. CONCLUSION: The incidence of cardia adenocarcinoma is seemingly rapidly increasing in younger women, while it has been stable in other groups during recent years in Sweden. The incidence of non-cardia gastric adenocarcinoma continues to decrease, particularly in older men. PMID- 29600887 TI - Prognosis of dolichoectasia in non-cardioembolic transient ischemic attack and minor stroke. AB - Objectives This study aimed to estimate the prognosis of dolichoectasia in non cardioembolic transient ischemic attack (TIA) and minor stroke patients. Methods Data were derived from the imaging subgroup of patients in the Clopidogrel in High-risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. Dolichoectasia was defined as ectasia (basilar artery diameter >4.5 mm) and dolichosis (either basilar artery bifurcation above the suprasellar cistern or lateral to the margin of the clivus or dorsum sellae). The prognosis included ischemic stroke recurrence and poor functional outcome (modified Rankin scale 2 6) at 12-month follow-up. The association of dolichoectasia with risk factors and prognosis of patients were assessed using multivariable Cox regression models. Results Overall, 1089 patients with magnetic resonance images in the CHANCE trial were included in this subanalysis. A total of 98 (9.0%) patients were detected with dolichoectasia, and 106 (9.7%) patients had a recurrent ischemic stroke at 12 months. Small artery occlusion (SAO) was more prevalent in patients with dolichoectasia compared with those without dolichoectasia (29.6% vs. 22.7%, hazard ratio [HR] 2.87, 95% confidence interval [CI] 1.59-5.17, p < 0.001). However, multivariate analysis showed no association of dolichoectasia with 12 month recurrent stroke (9.2% vs. 9.8%, HR, 1.15; 95%CI, 0.32-4.12; p = 0.83) and poor functional outcome (7.6% vs. 8.4%, odds ratio, 1.22; 95%CI, 0.24-6.08; p = 0.81) in the current subgroup analysis. Conclusions Dolichoectasia was significantly associated with SAO. There was no relationship between dolichoectasia and 12-month prognosis of patients with non-cardioembolic TIA or minor stroke. PMID- 29600888 TI - Genetic Variation of 'Candidatus Liberibacter solanacearum' Haplotype C and Identification of a Novel Haplotype from Trioza urticae and Stinging Nettle. AB - 'Candidatus Liberibacter solanacearum' (CLso) haplotype C is associated with disease in carrots and transmitted by the carrot psyllid Trioza apicalis. To identify possible other sources and vectors of this pathogen in Finland, samples were taken of wild plants within and near the carrot fields, the psyllids feeding on these plants, parsnips growing next to carrots, and carrot seeds. For analyzing the genotype of the CLso-positive samples, a multilocus sequence typing (MLST) scheme was developed. CLso haplotype C was detected in 11% of the T. anthrisci samples, in 35% of the Anthriscus sylvestris plants with discoloration, and in parsnips showing leaf discoloration. MLST revealed that the CLso in T. anthrisci and most A. sylvestris plants represent different strains than the bacteria found in T. apicalis and the cultivated plants. CLso haplotype D was detected in 2 of the 34 carrot seed lots tested, but was not detected in the plants grown from these seeds. Phylogenetic analysis by unweighted-pair group method with arithmetic means clustering suggested that haplotype D is more closely related to haplotype A than to C. A novel, sixth haplotype of CLso, most closely related to A and D, was found in the psyllid T. urticae and stinging nettle (Urtica dioica, Urticaceae), and named haplotype U. PMID- 29600889 TI - Transcranial direct current stimulation in the modulation of neuropathic pain: a systematic review. AB - Objective To investigate the neuromodulating effect of Transcranial Direct Current Stimulation (tDCS) on Neuropathic Pain (NP). Method A systematic review of articles published in the past five years in MEDLINE, LILACS, Cochrane, Scopus, ScienceDirect, and PEDro. The search was carried out from February to May 2017 using the keywords: neuropathic pain, neuralgia, nerve pain, central pain, peripheral nerve pain, tDCS. The selected studies were full articles written in Portuguese, English, or Spanish with at least one control group, and no less than one pre- or post-intervention variable, with the exclusion of case studies or case series, animal model studies, and studies with combined therapy. The quality of the selected articles was evaluated through PEDro scale, whereas the level of agreement among reviewers was measured with the Cohen's kappa test, considering P < 0.05 to be significant. Results Eight articles were selected (PEDro: 8.5 +/- 0.6; Cohen's kappa test: 0.703, P < 0.01), six of which were randomized controlled trials and two were controlled clinical trials. The following causes of NP were observed: spinal cord injury (SCI), amputation, stroke, multiple sclerosis (MS), and radiculopathy. All of the studies showed significant effects of tDCS on NP when compared to the control group, except for one with SCI and another related to radiculopathy. Discussion The shortage of good quality articles, the varying of ramp-on and ramp-off durations, and number of sessions, as well as the diversity of results found did not allow any definite conclusion on the efficacy of the neuromodulating effect of tDCS on NP. PMID- 29600890 TI - Preoperative brain temperature imaging on proton magnetic resonance spectroscopy predicts hemispheric ischemia during carotid endarterectomy for unilateral carotid stenosis with inadequate collateral blood flow. AB - Objective Preoperative magnetic resonance (MR) angiography sometimes shows the absence of collateral flow via the circle of Willis. This study examined whether brain temperature (BT) imaging on multi-voxel proton MR spectroscopy after this finding increases the accuracy of predicting hemispheric ischemia during internal carotid artery (ICA) clamping during endarterectomy for patients with symptomatic unilateral carotid stenosis. Methods In 52 patients with ICA stenosis (>=70%) and absence of collateral blood flow via the circle of Willis on preoperative MR angiography, BT imaging was displayed using proton multi-voxel MR spectroscopy. The difference between BTs in the affected and contralateral hemispheres (BTaffected hemisphere - BTcontralateral hemisphere) in the deep white matter of the centrum semiovale was calculated and defined as hemispheric DeltaBT. Development of cerebral hemispheric ischemia during ICA clamping was determined from intraoperative electroencephalography (EEG). Results Multivariate analysis revealed that high preoperative hemispheric DeltaBT was significantly associated with development of EEG-defined hemispheric ischemia (95% confidence intervals [CIs], 5.376-15.452; p = 0.006). The positive-predictive value for development of EEG-defined hemispheric ischemia was significantly greater for preoperative hemispheric DeltaBT following preoperative MR angiography (95%CI, 42-87%) than for preoperative MR angiography alone (95%CI, 13-37%). Conclusions For patients without collateral flow via the circle of Willis, BT imaging increases the predictive accuracy for development of hemispheric ischemia during ICA clamping during CEA. PMID- 29600891 TI - The effect of normobaric oxygen in patients with acute stroke: a systematic review and meta-analysis. AB - Background Normobaric oxygen (NBO) has received considerable attention due to controversial data in brain protection in patients with acute stroke. This study aims to analyze current data of NBO on brain protection as used in the clinic. Methods We searched for and reviewed relevant articles and references from Pubmed, Medline, Embase, Cochrane, and Clincialtrials.gov that were published prior to October 2017. Data from prospective studies were processed using RevMan5.0 software, provided by Cochrane collaboration and transformed using relevant formulas. Results A total of 11 prospective RCT studies including 6366 patients with acute stroke (NBO group, 3207; control group, 3159) were enrolled in this analysis. ?NIHSS represented the values of NIHSS at 4, 24 h, or 7 days post-stroke minus baseline NIHSS. Compared to controls, there was a minor trend toward NBO benefits in short-term prognostic indices, as indicated by decreased DeltaNIHSS at our defined time points. By contrast, NBO decreased Barthel Index scores between 3 and 7 months, and increased death rates at 3, 6 months, and 1 year, whereas, modified Rankin Scale scores between 3 and 6 months were unchanged. Conclusions The existing trends toward benefits revealed in this meta analysis help us appreciate the promising value of NBO, although current evidence of NBO on improving clinical outcomes of stroke is insufficient. Well-designed multi-center clinical trials are encouraged and urgently needed to further explore the efficacy of NBO on brain protection.

AB - After myocardial infarction, remodeling of the left ventricle involves a wound healing orchestra involving a variety of cell types. In order for wound healing to be optimal, appropriate communication must occur; these cells all need to come in at the right time, be activated at the right time in the right amount, and know when to exit at the right time. When this occurs, a new homeostasis is obtained within the infarct, such that infarct scar size and quality are sufficient to maintain left ventricular size and shape. The ideal scenario does not always occur in reality. Often, miscommunication can occur between infarct and remote spaces, across the temporal wound-healing spectrum, and across organs. When miscommunication occurs, adverse remodeling can progress to heart failure. This review discusses current knowledge gaps and recent development of the roles of inflammation and the extracellular matrix in myocardial infarction remodeling. In particular, the macrophage is one cell type that provides direct and indirect regulation of both the inflammatory and scar-forming responses. We summarize current research efforts focused on identifying biomarker indicators that reflect the status of each component of the wound-healing process to better predict outcomes. PMID- 29600896 TI - Wavelet decomposition analysis is a clinically relevant strategy to evaluate cerebrovascular buffering of blood pressure after spinal cord injury. AB - The capacity of the cerebrovasculature to buffer changes in blood pressure (BP) is crucial to prevent stroke, the incidence of which is three- to fourfold elevated after spinal cord injury (SCI). Disruption of descending sympathetic pathways within the spinal cord due to cervical SCI may result in impaired cerebrovascular buffering. Only linear analyses of cerebrovascular buffering of BP, such as transfer function, have been used in SCI research. This approach does not account for inherent nonlinearity and nonstationarity components of cerebrovascular regulation, often depends on perturbations of BP to increase the statistical power, and does not account for the influence of arterial CO2 tension. Here, we used a nonlinear and nonstationary analysis approach termed wavelet decomposition analysis (WDA), which recently identified novel sympathetic influences on cerebrovascular buffering of BP occurring in the ultra-low frequency range (ULF; 0.02-0.03Hz). WDA does not require BP perturbations and can account for influences of CO2 tension. Supine resting beat-by-beat BP (Finometer), middle cerebral artery blood velocity (transcranial Doppler), and end-tidal CO2 tension were recorded in cervical SCI ( n = 14) and uninjured ( n = 16) individuals. WDA revealed that cerebral blood flow more closely follows changes in BP in the ULF range ( P = 0.0021, Cohen's d = 0.89), which may be interpreted as an impairment in cerebrovascular buffering of BP. This persisted after accounting for CO2. Transfer function metrics were not different in the ULF range, but phase was reduced at 0.07-0.2 Hz ( P = 0.03, Cohen's d = 0.31). Sympathetically mediated cerebrovascular buffering of BP is impaired after SCI, and WDA is a powerful strategy for evaluating cerebrovascular buffering in clinical populations. PMID- 29600897 TI - Influence of myocardial oxygen demand on the coronary vascular response to arterial blood gas changes in humans. AB - It remains unclear if the human coronary vasculature is inherently sensitive to changes in arterial Po2 and Pco2 or if coronary vascular responses are the result of concomitant increases in myocardial O2 consumption/demand ([Formula: see text]). We hypothesized that the coronary vascular response to Po2 and Pco2 would be attenuated in healthy men when [Formula: see text] was attenuated with beta1 adrenergic receptor blockade. Healthy men (age: 25 +/- 1 yr, n = 11) received intravenous esmolol (beta1-adrenergic receptor antagonist) or volume-matched saline in a double-blind, randomized crossover study and were exposed to poikilocapnic hypoxia, isocapnic hypoxia, and hypercapnic hypoxia. Measurements made at baseline and after 5 min of steady state at each gas manipulation included left anterior descending coronary blood velocity (LADV; Doppler echocardiography), heart rate, and arterial blood pressure. LADV values at the end of each hypoxic condition were compared between esmolol and placebo. The rate pressure product (RPP) and left ventricular mechanical energy (MELV) were calculated as indexes of [Formula: see text]. All gas manipulations augmented RPP, MELV, and LADV, but only RPP and MELV were attenuated (4-18%) after beta1 adrenergic receptor blockade ( P < 0.05). Despite attenuated RPP and MELV responses, beta1-adrenergic receptor blockade did not attenuate the mean LADV vasodilatory response compared with placebo during poikilocapnic hypoxia (29.4 +/ 2.2 vs. 27.3 +/- 1.6 cm/s) and isocapnic hypoxia (29.5 +/- 1.5 vs. 30.3 +/- 2.2 cm/s). Hypercapnic hypoxia elicited a feedforward coronary dilation that was blocked by beta1-adrenergic receptor blockade. These results indicate a direct influence of arterial Po2 on coronary vascular regulation that is independent of [Formula: see text]. NEW & NOTEWORTHY In humans, arterial hypoxemia led to an increase in epicardial coronary artery blood velocity. beta1-Adrenergic receptor blockade did not diminish the hypoxemic coronary response despite reduced myocardial O2 demand. These data indicate hypoxemia can regulate coronary blood flow independent of myocardial O2 consumption. A plateau in the mean left anterior descending coronary artery blood velocity-rate-pressure product relationship suggested beta1-adrenergic receptor-mediated, feedforward epicardial coronary artery dilation. In addition, we observed a synergistic effect of Po2 and Pco2 during hypercapnic hypoxia. PMID- 29600898 TI - Specific circulating microRNAs display dose-dependent responses to variable intensity and duration of endurance exercise. AB - Circulating microRNAs (c-miRNAs), plasma-based noncoding RNAs that control posttranscriptional gene expression, mediate processes that underlie phenotypical plasticity to exercise. The relationship and biological relevance between c-miRNA expression and variable dose exercise exposure remains uncertain. We hypothesized that certain c-miRNAs respond to changes in exercise intensity and/or duration in a dose-dependent fashion. Muscle release of such c-miRNAs may then deplete intracellular stores, thus facilitating gene reprogramming and exercise adaptation. To address these hypotheses, healthy men participated in variable intensity ( n = 12, 30 * 1 min at 6, 7, and 8 miles/h, order randomized) and variable duration ( n = 14, 7 * 1 mile/h for 30, 60, and 90 min, order randomized) treadmill-running protocols. Muscle-enriched c-miRNAs (i.e., miRNA-1 and miRNA-133a) and others with known relevance to exercise were measured before and after exercise. c-miRNA responses followed three profiles: 1) nonresponsive (miRNA-21 and miRNA-210), 2) responsive to exercise at some threshold but without dose dependence (miRNA-24 and miRNA-146a), and 3) responsive to exercise with dose dependence to increasing intensity (miRNA-1) or duration (miRNA-133a and miRNA-222). We also studied aerobic exercise-trained mice, comparing control, low intensity (0.5 km/h), or high-intensity (1 km/h) treadmill-running protocols over 4 wk. In high- but not low-intensity-trained mice, we found increased plasma c miR-133a along with decreased intracellular miRNA-133a and increased serum response factor, a known miR-133a target gene, in muscle. Characterization of c miRNAs that are dose responsive to exercise in humans and mice supports the notion that they directly mediate physiological adaptation to exercise, potentially through depletion of intracellular stores of muscle-specific miRNAs. NEW & NOTEWORTHY In this study of humans and mice, we define circulating microRNAs in plasma that are dose responsive to exercise. Our data support the notion that these microRNAs mediate physiological adaptation to exercise potentially through depletion of intracellular stores of muscle-specific microRNAs and releasing their inhibitory effects on target gene expression. PMID- 29600900 TI - Bilirubin acts as a multipotent guardian of cardiovascular integrity: more than just a radical idea. AB - Bilirubin, a potentially toxic catabolite of heme and indicator of hepatobiliary insufficiency, exhibits potent cardiac and vascular protective properties. Individuals with Gilbert's syndrome (GS) may experience hyperbilirubinemia in response to stressors including reduced hepatic bilirubin excretion/increased red blood cell breakdown, with individuals usually informed by their clinician that their condition is of little consequence. However, GS appears to protect from all cause mortality, with progressively elevated total bilirubin associated with protection from ischemic heart and chronic obstructive pulmonary diseases. Bilirubin may protect against these diseases and associated mortality by reducing circulating cholesterol, oxidative lipid/protein modifications, and blood pressure. In addition, bilirubin inhibits platelet activation and protects the heart from ischemia-reperfusion injury. These effects attenuate multiple stages of the atherosclerotic process in addition to protecting the heart during resultant ischemic stress, likely underpinning the profound reduction in cardiovascular mortality in hyperbilirubinemic GS. This review outlines our current knowledge of and uses for bilirubin in clinical medicine and summarizes recent progress in revealing the physiological importance of this poorly understood molecule. We believe that this review will be of significant interest to clinicians, medical researchers, and individuals who have GS. PMID- 29600899 TI - Human muscle-specific A-kinase anchoring protein polymorphisms modulate the susceptibility to cardiovascular diseases by altering cAMP/PKA signaling. AB - One of the crucial cardiac signaling pathways is cAMP-mediated PKA signal transduction, which is regulated by a family of scaffolding proteins, i.e., A kinase anchoring proteins (AKAPs). Muscle-specific AKAP (mAKAP) partly regulates cardiac cAMP/PKA signaling by binding to PKA and phosphodiesterase 4D3 (PDE4D3), among other proteins, and plays a central role in modulating cardiac remodeling. Moreover, genetics plays an incomparable role in modifying the risk of cardiovascular diseases (CVDs). Single-nucleotide polymorphisms (SNPs) in various proteins have especially been shown to predispose individuals to CVDs. Hence, we hypothesized that human mAKAP polymorphisms found in humans with CVDs alter the cAMP/PKA pathway, influencing the susceptibility of individuals to CVDs. Our computational analyses revealed two mAKAP SNPs found in cardiac disease-related patients with the highest predicted deleterious effects, Ser 1653 Arg (S1653R) and Glu 2124 Gly (E2124G). Coimmunoprecipitation data in human embryonic kidney 293T cells showed that the S1653R SNP, present in the PDE4D3-binding domain of mAKAP, changed the binding of PDE4D3 to mAKAP and that the E2124G SNP, flanking the 3'-PKA binding domain, changed the binding of PKA before and after stimulation with isoproterenol. These SNPs significantly altered intracellular cAMP levels, global PKA activity, and cytosolic PDE activity compared with the wild type before and after isoproterenol stimulation. PKA-mediated phosphorylation of pathological markers was found to be upregulated after cell stimulation in both mutants. In conclusion, human mAKAP polymorphisms may influence the propensity of developing CVDs by affecting cAMP/PKA signaling, supporting the clinical significance of PKA-mAKAP-PDE4D3 interactions. NEW & NOTEWORTHY We found that single-nucleotide polymorphisms in muscle-specific A kinase anchoring protein found in human patients with cardiovascular diseases significantly affect the cAMP/PKA signaling pathway. Our results showed, for the first time, that human muscle-specific A-kinase anchoring protein polymorphisms might alter the susceptibility of individuals to develop cardiovascular diseases with known underlying molecular mechanisms.

AB - The embryological development of the central nervous system takes place during the neurulation process, which includes primary and secondary neurulation. A new form of dysraphism, named junctional neural tube defect (JNTD), was recently reported, with only 4 cases described in the literature. The authors report a fifth case of JNTD. This 5-year-old boy, who had been operated on during his 1st month of life for a uretero-rectal fistula, was referred for evaluation of possible spinal dysraphism. He had urinary incontinence, clubfeet, and a history of delayed walking ability. MRI showed a spinal cord divided in two, with an upper segment ending at the T-11 level and a lower segment at the L5-S1 level, with a thickened filum terminale. The JNTDs represent a recently classified dysraphism caused by an error during junctional neurulation. The authors suggest that their patient should be included in this category as the fifth case reported in the literature and note that this would be the first reported case of JNTD in association with a lipomatous filum terminale. PMID- 29600905 TI - Therapeutic outcomes of transsphenoidal surgery in pediatric patients with craniopharyngiomas: a single-center study. AB - OBJECTIVE The aim of this study was to analyze the outcomes of transsphenoidal surgery (TSS) in a single-center clinical series of pediatric craniopharyngioma patients treated with gross-total resection (GTR). METHODS The authors retrospectively reviewed the surgical outcomes for 65 consecutive patients with childhood craniopharyngiomas (28 girls and 37 boys, mean age 9.6 years) treated with TSS (45 primary and 20 repeat surgeries) between 1990 and 2015. Tumors were classified as subdiaphragmatic or supradiaphragmatic. Demographic and clinical characteristics, including extent of resection, complications, incidence of recurrence, pre- and postoperative visual disturbance, pituitary function, and incidence of diabetes insipidus (DI), as well as new-onset obesity, were analyzed and compared between the primary surgery and repeat surgery groups. RESULTS Of the 45 patients in the primary surgery group, 26 (58%) had subdiaphragmatic tumors and 19 had supradiaphragmatic tumors. Of the 20 patients in the repeat surgery group, 9 (45%) had subdiaphragmatic tumors and 11 had supradiaphragmatic tumors. The only statistically significant difference between the 2 surgical groups was in tumor size; tumors were larger (mean maximum diameter 30 mm) in the primary surgery group than in the repeat surgery group (25 mm) (p = 0.008). GTR was accomplished in 59 (91%) of the 65 cases; the GTR rate was higher in the primary surgery group than in the repeat surgery group (98% vs 75%, p = 0.009). Among the patients who underwent GTR, 12% experienced tumor recurrence, with a median follow-up of 7.8 years, and recurrence tended to occur less frequently in primary than in repeat surgery patients (7% vs 27%, p = 0.06). Of the 45 primary surgery patients, 80% had deteriorated pituitary function and 83% developed DI, whereas 100% of the repeat surgery patients developed these conditions. Among patients with preoperative visual disturbance, vision improved in 62% but worsened in 11%. Visual improvement was more frequent in primary than in repeat surgery patients (71% vs 47%, p < 0.001), whereas visual deterioration was less frequent following primary surgery than repeat surgery (4% vs 24%, p = 0.04). Among the 57 patients without preoperative obesity, new-onset postoperative obesity was found in 9% of primary surgery patients and 21% of repeat surgery patients (p = 0.34) despite aggressive resection, suggesting that hypothalamic dysfunction was rarely associated with GTR by TSS in this series. However, obesity was found in 25% of the repeat surgery patients preoperatively due to prior transcranial surgery. Although there were no perioperative deaths, there were complications in 12 cases (18%) (6 cases of CSF leaks, 3 cases of meningitis, 2 cases of transient memory disturbance, and 1 case of hydrocephalus). Postoperative CSF leakage appeared to be more common in repeat than in primary surgery patients (20% vs 4.4%, p = 0.2). CONCLUSIONS The results of TSS for pediatric craniopharyngioma in this case series suggest that GTR should be the goal for the first surgical attempt. GTR should be achievable without serious complications, although most patients require postoperative hormonal replacement. When GTR is not possible or tumor recurrence occurs after GTR, radiosurgery is recommended to prevent tumor regrowth or progression. PMID- 29600906 TI - Letter to the Editor.

PMID- 29600907 TI - Posterior-approach single-level apical spinal osteotomy in pediatric patients for severe rigid kyphoscoliosis: long-term clinical and radiological outcomes. AB - OBJECTIVE Spinal osteotomy in pediatric patients is challenging due to various factors. For correction of severe rigid kyphoscoliosis in children, numerous techniques with anterior or posterior or combined approaches, as well as multilevel osteotomies, have been described. These techniques are associated with prolonged operative times and large amounts of blood loss. The purpose of this study was to evaluate the clinical and radiologically confirmed efficacy of a modification of the apical spinal osteotomy (ASO) technique-posterior-only single level asymmetric closing osteotomy-in pediatric patients with severe rigid kyphoscoliosis. METHODS The authors performed a retrospective study of a case series involving pediatric patients with severe spinal deformity operated on by a single surgeon at a single institution over a period of approximately 5 years. The inclusion criteria were age < 14 years, rigid thoracic/thoracolumbar/lumbar kyphosis (> 70 degrees ) with or without neurological deficit and with or without scoliosis, and a minimum of 2 years of follow-up. Patients with cervical or lumbosacral kyphoscoliosis were excluded from the study. Demographic and clinical parameters, including age, sex, etiology of kyphoscoliosis, neurological examination status (Frankel grade), and visual analog scale (VAS) and Oswestry Disability Index (ODI) scores, were noted. Operative parameters (level of osteotomy, number of levels fused, duration of surgery, blood loss, and complications) were also recorded. Radiological assessment was done for preoperative and postoperative kyphosis and scoliosis as well as the final Cobb angle. Similarly, sagittal vertical axis (SVA) correction was calculated. Fusion was assessed in all patients at the final follow-up evaluation. RESULTS A total of 26 pediatric patients (18 male and 8 female) with a mean age of 9 years met the inclusion criteria and had data available for analysis, and all of these patients had severe scoliosis as well as kyphosis. Comparison of preoperative and postoperative values showed a significant improvement (p < 0.05) in radiological, clinical, and functional parameters (Cobb angle for scoliosis and kyphosis, SVA, VAS, and ODI). With respect to kyphosis, the mean preoperative Cobb angle was 96.54 degrees , the mean postoperative angle was 30.77 degrees , and the mean angle at final follow-up was 34.81 degrees (average loss of correction of 4.23 degrees ), for a final average correction of 64.15%. With respect to scoliosis, the mean preoperative angle was 52.54 degrees , the mean postoperative angle was 15.77 degrees , and the mean angle at final follow-up was 19.42 degrees (average loss of correction of 3.66 degrees ), for a final average correction of 60.95%. The preoperative SVA averaged 7.6 cm; the mean SVA improved to 3.94 cm at the end of 2 years. Bony fusion was achieved in all patients. The mean number of levels fused was 5.69. The mean operative time was 243.46 minutes, with an average intraoperative blood loss of 336.92 ml. Nonneurological complications occurred in 15.39% of patients (2 dural tears, 1 superficial infection, 1 implant failure). At the 2-year follow-up, 25 of the 26 patients had maintained or improved their neurological status. One patient developed paraplegia immediately after the operation and recovered only partially. CONCLUSIONS Analysis of data from this series of 26 cases indicates that this posterior-approach single-level technique is effective for the correction of severe rigid kyphoscoliosis in pediatric patients, providing good clinical and radiological results in most cases. PMID- 29600908 TI - Pedicle screws with a thin hydroxyapatite coating for improving fixation at the bone-implant interface in the osteoporotic spine: experimental study in a porcine model. AB - OBJECTIVE Instrumentation failure caused by the loosening of pedicle screws (PSs) in patients with osteoporosis is a serious problem after spinal surgery. The addition of a thin hydroxyapatite (HA) surface coating applied by using a sputtering process was reported recently to be a promising method for providing bone conduction around an implant without a significant risk of coating-layer breakage. In this study, the authors evaluated the biomechanical and histological features of the bone-implant interface (BII) of PSs with a thin HA coating in an in vivo porcine osteoporotic spine model. METHODS Three types of PSs (untreated/standard [STPS], sandblasted [BLPS], and HA-coated [HAPS] PSs) were implanted into the thoracic and lumbar spine (T9-L6) of 8 mature Clawn miniature pigs (6 ovariectomized [osteoporosis group] and 2 sham-operated [control group] pigs). The spines were harvested from the osteoporosis group at 0, 2, 4, 8, 12, or 24 weeks after PS placement and from the control group at 0 or 24 weeks. Their bone mineral density (BMD) was measured by peripheral quantitative CT. Histological evaluation of the BIIs was conducted by performing bone volume/tissue volume and bone surface/implant surface measurements. The strength of the BII was evaluated with extraction torque testing. RESULTS The BMD decreased significantly in the osteoporosis group (p < 0.01). HAPSs exhibited the greatest mean extraction peak torque at 8 weeks, and HAPSs and BLPSs exhibited significantly greater mean torque than the STPSs at 12 weeks (p < 0.05). The bone surface/implant surface ratio was significantly higher for HAPSs than for STPSs after 2 weeks (p < 0.05), and bonding between bone and the implant surface was maintained until 24 weeks with no detachment of the coating layer. In contrast, the bone volume/tissue volume ratio was significantly higher for HAPSs than for BLPSs or STPSs only at 4 weeks. CONCLUSIONS Using PSs with a thin HA coating applied using a sputtering process strengthens bonding at the BII, which might improve early implant fixation after spinal surgery for osteoporosis. However, the absence of increased bone mass around the screw remains a concern; prescribing osteoporosis treatment to improve bone quality might be necessary to prevent fractures around the screws. PMID- 29600909 TI - Spontaneous occult intracranial hypotension precipitating life-threatening cerebral venous thrombosis: case report. AB - Spontaneous intracranial hypotension (SIH) is an uncommon headache etiology, typically attributable to an unprovoked occult spinal CSF leak. Although frequently benign, serious complications may occur, including cerebral venous thrombosis (CVT). The objective of this study was to examine a highly complicated case of CVT attributable to SIH as a lens for understanding the heterogeneous literature on this rare complication, and to provide useful, evidence-based, preliminary clinical recommendations. A 43-year-old man presented with 1 week of headache, dizziness, and nausea, which precipitously evolved to hemiplegia. CT venography confirmed CVT, and therapeutic heparin was initiated. He suffered a generalized seizure due to left parietal hemorrhage, which subsequently expanded. He developed signs of mass effect and herniation, heparin was discontinued, and he was taken to the operating room for clot evacuation and external ventricular drain placement. Intraoperatively, the dura was deflated, suggesting underlying SIH. Ventral T-1 CSF leak was identified, which failed multiple epidural blood patches and required primary repair. The patient ultimately made a complete recovery. Systematic review identified 29 publications describing 36 cases of SIH associated CVT. Among 31 patients for whom long-term neurological outcome was reported, 25 (81%) recovered completely. Underlying coagulopathy/risk factors were identified in 11 patients (31%). CVT is a rare and potentially lethal sequela occurring in 2% of SIH cases. Awareness of the condition is poor, risking morbid complications. Evaluation and treatment should be directed toward identification and treatment of occult CSF leaks. Encouragingly, good neurological outcomes can be achieved through vigilant multidisciplinary neurosurgical and neurocritical care. PMID- 29600910 TI - Retrospective single-surgeon study of 1123 consecutive cases of anterior cervical discectomy and fusion: a comparison of clinical outcome parameters, complication rates, and costs between outpatient and inpatient surgery groups, with a literature review. AB - OBJECTIVE Outpatient anterior cervical discectomy and fusion (ACDF) is becoming more common and has been reported to offer advantages over inpatient procedures, including reducing nosocomial infections and costs, as well as improving patient satisfaction. The goal of this retrospective study was to evaluate and compare outcome parameters, complication rates, and costs between inpatient and outpatient ACDF cases performed by 1 surgeon at a single institution. METHODS In a retrospective study, the records of all patients who had undergone first-time ACDF performed by a single surgeon in the period from June 1, 2003, to January 31, 2016, were reviewed. Patients were categorized into 2 groups: those who had undergone ACDF as outpatients in a same-day surgical center and those who had undergone surgery in the hospital with a minimum 1-night stay. Outcomes for all patients were evaluated with respect to the following parameters: age, sex, length of stay, preoperative and postoperative pain (self-reported questionnaires), number of levels fused, fusion, and complications, as well as the presence of risk factors, such as an increased body mass index, smoking, and diabetes mellitus. RESULTS In total, 1123 patients were operated on, 485 (43%) men and 638 (57%) women, whose mean age was 50 years. The mean follow-up time was 25 months. Overall, 40.5% underwent 1-level surgery, 34.3% 2-level, 21.9% 3 level, and 3.2% 4-level. Only 5 patients had nonunion of vertebrae; thus, the fusion rate was 99.6%. Complications occurred in 40 patients (3.6%), with 9 having significant complications (0.8%). Five hundred sixty patients (49.9%) had same-day surgery, and 563 patients (50.1%) stayed overnight in the hospital. The inpatients were older, were more commonly male, and had a higher rate of diabetes. Smoking status did not influence the length of stay. Both groups had a statistically significant reduction in pain (expressed as a visual analog scale score) postoperatively with no significant difference between the groups. One- and 2-level surgeries were done significantly more often in the outpatient setting (p < 0.001). The complication rate was 4.1% in the outpatient group and 3.0% in the inpatient group; there was no statistically significant difference between the 2 groups (p = 0.339). Significantly more complications occurred with 3- and 4-level surgeries than with 1- and 2-level procedures (p < 0.001, chi square test). The overall average inpatient cost for commercial insurance carriers was 26% higher than those for outpatient surgery. CONCLUSIONS Anterior cervical discectomy and fusion is safe for patients undergoing 1- or 2-level surgery, with a very significant rate of pain reduction and fusion and a low complication rate in both clinical settings. Outpatient and inpatient groups undergoing 3- or 4-level surgery had an increased risk of complications (compared with those undergoing 1- or 2-level surgery), with a negligible difference between the 2 groups. This finding suggests that these procedures can also be included as standard outpatient surgery. Comparable outcome parameters and the same complication rates between inpatient and outpatient groups support both operative environments. PMID- 29600911 TI - Intraoperative monitoring with visual evoked potentials for brain surgeries. AB - OBJECTIVE The goal of this study was to determine the performance of intraoperative visual evoked potentials (VEPs) in detecting visual field changes. METHODS Assessments of VEPs were performed with simultaneous retinal responses by using white light-emitting diodes protected from scialytic microscope lights. The alarm criterion was a reproducible decrease in amplitude of the VEP P100 wave of 20% or more. Visual fields were assessed preoperatively and 1 month postsurgery (Goldmann perimetry). RESULTS The VEPs were analyzed for 29 patients undergoing resection of a brain lesion. In 89.7% of patients, steady VEP and retinal responses were obtained for monitoring. The absence of alarm was associated in 94.4% of cases with the absence of postoperative visual changes (specificity). The alarms correctly identified 66.7% of cases with any postoperative changes and 100% of cases with changes more severe than just a discrete quadrantanopia or deterioration of an existing quadrantanopia (sensitivity, new diffuse deterioration < 2 dB). In 11.5% of patients, a transitory VEP decrease with subsequent recovery was observed without postoperative defects. CONCLUSIONS Intraoperative VEPs were performed with simultaneous recording of electroretinograms, with protection from lights of the operating room and with white light-emitting diodes. Intraoperative VEPs were shown to be reliable in predicting postoperative visual field changes. In this series of intraaxial brain procedures, reliable intraoperative VEP monitoring was achieved, allowing at minimum the detection of new quadrantanopia. The standardization of this technique appears to be a valuable effort in regard to the functional risks of homonymous hemianopia. PMID- 29600912 TI - Reduced risk of venous thromboembolism with the use of intermittent pneumatic compression after craniotomy: a randomized controlled prospective study. AB - OBJECTIVE The term "venous thromboembolism" (VTE) subsumes deep venous thrombosis (DVT) and pulmonary embolism. The incidence of DVT after craniotomy was reported to be as high as 50%. Even clinically silent DVT may lead to potentially fatal pulmonary embolism. The risk of VTE is correlated with duration of surgery, and it appears likely that it develops during surgery. The present study aimed to evaluate intraoperative use of intermittent pneumatic compression (IPC) of the lower extremity for prevention of VTE in patients undergoing craniotomy. METHODS A total of 108 patients undergoing elective craniotomy for intracranial pathology were included in a single-center controlled randomized prospective study. In the control group, conventional compression stockings were worn during surgery. In the treatment group, IPC of the calves was used in addition. The presence of DVT was evaluated by Doppler sonography pre- and postoperatively. RESULTS Intraoperative use of IPC led to a significant reduction of VTE (p = 0.029). In logistic regression analysis, the risk of VTE was approximately quartered by the use of IPC. Duration of surgery was confirmed to be correlated with VTE incidence (p < 0.01); every hour of surgery increased the risk by a factor of 1.56. CONCLUSIONS Intraoperative use of IPC significantly lowers the incidence of potentially fatal VTE in patients undergoing craniotomy. The method is easy to use and carries no additional risks. ? CLASSIFICATION OF EVIDENCE Type of question: therapeutic; study design: randomized controlled trial; evidence: class I. Clinical trial registration no.: DRKS00011783 ( https://www.drks.de ). PMID- 29600913 TI - Natural history of cavernous sinus meningiomas. AB - OBJECTIVE Meningiomas confined to the cavernous sinus (MCSs) are benign tumors. Due to the high risk of severe complications, the intracavernous surgical procedure was abandoned in favor of radiotherapy. However, the choice of treatment remains complicated due to the fact that the natural history of this lesion has not yet been described. METHODS The authors studied the natural history of this lesion using a prospective series of 53 consecutive patients suffering from MCSs. The median follow-up duration was 10.2 years (range 2-25 years), from 1990 to 2016. RESULTS Patients ranged in age from 30 to 72 years (mean 53 years). The meningiomas were diagnosed by major symptoms (mainly oculomotor palsy and neuralgia experienced in 28 patients), minor symptoms (headache, intermittent diplopia in 15 patients), or incidental findings (10 patients). Simple symptomatic treatment (short courses of corticosteroids and carbamazepine) allowed patients to become asymptomatic in 19 (67.9%) of 28 cases experiencing major symptoms, and for 12 (80%) of 15 patients with initial minor symptoms (p < 0.0001). All patients with incidental findings remained asymptomatic. Forty four (83%) of 53 MCSs did not show any significant growth and 42 (80%) of 53 patients were not symptomatic at the end of follow-up (p < 0.001). The radiographic progression-free survival rates (+/- SD) at 5, 10, and 20 years were 90% +/- 4.2%, 82% +/- 5.7%, and 70% +/- 10.2%, respectively. Five patients (9.4%) with no evidence of any effect of the initial medical treatment desired additional conventional radiation therapy. CONCLUSIONS Because of the capricious, unpredictable, and slow growth of MCSs, together with high growth variability from one patient to the next, the symptomatic medical treatment of these tumors is a highly effective method. This series shows that these lesions are naturally, clinically, and radiologically indolent. PMID- 29600914 TI - Editorial. Indication and technique for using the Pipeline embolization device to treat intracranial aneurysms. PMID- 29600915 TI - Predictors of cerebral aneurysm persistence and occlusion after flow diversion: a single-institution series of 445 cases with angiographic follow-up. AB - OBJECTIVE Flow diversion requires neointimal stent overgrowth to deliver aneurysm occlusion. The existing literature on aneurysm occlusion is limited by heterogeneous follow-up, variable antiplatelet regimens, noninvasive imaging modalities, and nonstandard occlusion assessment. Using a large, single-center cohort with low attrition and standardized antiplatelet tapering, the authors evaluated outcomes after flow diversion of anterior circulation aneurysms to identify predictors of occlusion and aneurysm persistence. METHODS Data from a prospective, IRB-approved database was analyzed for all patients with anterior circulation aneurysms treated by flow diversion with the Pipeline embolization device (PED) at the authors' institution. Follow-up consisted of catheter cerebral angiography at 6 and 12 months postembolization. Clopidogrel was discontinued at 6 months and aspirin was reduced to 81 mg daily at 12 months. Occlusion was graded as complete, trace filling, entry remnant, or aneurysm filling. Multivariate logistic regression was performed to identify predictors of aneurysm persistence. RESULTS Follow-up catheter angiography studies were available for 445 (91%) of 491 PED procedures performed for anterior circulation aneurysms between August 2011 and August 2016. Three hundred eighty-seven patients accounted for these 445 lesions with follow-up angiography. The population was 84% female; mean age was 56 years and mean aneurysm size was 6.6 mm. Aneurysms arose from the internal carotid artery (83%), anterior cerebral artery (13%), and middle cerebral artery (4%). Morphology was saccular in 90% of the lesions, and 18% of the aneurysms has been previously treated. Overall, complete occlusion was achieved in 82% of cases at a mean follow-up of 14 months. Complete occlusion was achieved in 72%, 78%, and 87% at 6, 12, and 24 months, respectively. At 12 months, adjunctive coiling predicted occlusion (OR 0.260, p = 0.036), while male sex (OR 2.923, p = 0.032), aneurysm size (OR 3.584, p = 0.011), and incorporation of a branch vessel (OR 2.206, p = 0.035) predicted persistence. Notable variables that did not predict aneurysm occlusion were prior treatments, vessel of origin, fusiform morphology, and number of devices used. CONCLUSIONS This is the largest single-institution study showing high rates of anterior circulation aneurysm occlusion after Pipeline embolization. Predictors of persistence after flow diversion included increasing aneurysm size and incorporated branch vessel, whereas adjunctive coiling predicted occlusion. PMID- 29600916 TI - Risk factors for and outcomes of postoperative complications in adult patients with moyamoya disease. AB - OBJECTIVE The risk factors and clinical significance of postoperative complications in moyamoya disease are still unclear. The aim of this study was to investigate the predictors of postoperative complications in moyamoya disease and examine the impact of complications on outcomes. METHODS The authors reviewed consecutive cases involving adult moyamoya disease patients who underwent indirect, direct, or combined bypass surgery in their hospital between 2009 and 2015. Preoperative clinical characteristics and radiographic features were recorded. Postoperative complications within 14 days after surgery were examined. Multivariate logistic regression analyses were performed to identify the risk factors for either postoperative ischemia or postoperative cerebral hyperperfusion. Outcome data, including recurrent strokes and neurological status (modified Rankin Scale [mRS]) during follow-up, were collected. Outcomes were compared between patients who had complications with those without complications, using propensity-score analysis to account for between-group differences in baseline characteristics. RESULTS A total of 500 patients (610 hemispheres) were included in this study. Postoperative complications were observed in 74 operations (12.1%), including new postoperative ischemia in 30 cases (4.9%), hyperperfusion in 27 (4.4%), impaired wound healing in 12 (2.0%), and subdural effusion in 6 (1.0%). The complication rates for different surgery types were as follows: 12.6% (n = 25) for indirect bypass, 12.7% (n = 37) for direct bypass, and 10.0% (n = 12) for combined bypass (p = 0.726). Postoperative ischemic complications occurred in 30 hemispheres (4.9%) in 30 different patients, and postoperative symptomatic hyperperfusion occurred after 27 procedures (4.4%). Advanced Suzuki stage (OR 1.669, 95% CI 1.059-2.632, p = 0.027) and preoperative ischemic presentation (OR 5.845, 95% CI 1.654-20.653, p = 0.006) were significantly associated with postoperative ischemia. Preoperative ischemic presentation (OR 5.73, 95% CI 1.27-25.88, p = 0.023) and admission modified Rankin Scale (mRS) score (OR 1.81, 95% CI 1.06-3.10, p = 0.031) were significantly associated with symptomatic postoperative cerebral hyperperfusion syndrome (CHS). Compared with patients without postoperative complications, patients who experienced any postoperative complications had longer hospital stays and worse mRS scores at discharge (both p < 0.0001). At the final follow up, no significant differences in functional disability (mRS score 3-6, 11.9% vs 4.5%, p = 0.116) and future stroke events (p = 0.513) between the 2 groups were detected. CONCLUSIONS Advanced Suzuki stage and preoperative ischemic presentation were independent risk factors for postoperative ischemia; the mRS score on admission and preoperative ischemic presentation were independently associated with postoperative CHS. Although patients with postoperative complications had worse neurological status at discharge, postoperative complications had no associations with future stroke events or functional disability during follow-up.

AB - - Motion sickness is not a disorder, but a normal response to a non-normal situation in which movement plays a central role, such as car travel, sailing, flying, or virtual reality.- Almost anyone can suffer from motion sickness, as long as at least one of the organs of balance functions. If neither of the organs of balance functions the individual will not suffer from carsickness, seasickness, airsickness, nor from cybersickness. - 'Cybersickness' is a form of motion sickness that is stimulated by artificial moving images such as in videogames. Because we are now exposed more often and for longer periods of time to increasingly realistic artificial images, doctors will also encounter cases of motion sickness more often. - The basis for motion sickness is the vestibular system, which can be modulated by visual-vestibular conflicts, i.e. when the movements seen by the eyes are not the same as those experienced by the organs of balance.- Antihistamines can be effective against motion sickness in everyday situations such as car travel if taken before departure, but the effectiveness of medication for motion sickness is limited.

DESIGN: A digital questionnaire was sent to all elderly care physicians-in training and their trainers in the Netherlands, and to all 23 municipal coroners in the Mid-Holland region. METHOD: As well as questions on knowledge of the Dutch law and prognostic figures concerning dementia-related death, the questionnaire described two cases with minimal differences. The respondents were asked if they would issue a certificate of natural death in each case, and if not, would they have preferred to do so. They were also asked to explain their answers. RESULTS: Of the 405 elderly care physicians who responded, 68% and 49%, respectively, would have issued a certificate stating the cause to be natural death in each case, or if they did not they would have preferred to do so. All 15 coroners who filled in the questionnaire came to the conclusion of unnatural death. CONCLUSION: The majority of the elderly care physicians feel that a certificate of natural death can be issued if a fall in a nursing home results in a fracture, as this can be considered as part of the disease process of dementia.

AB - OBJECTIVE: The aim of these studies was to examine the influence of hospital of diagnosis on the probability of receiving curative treatment and its impact on survival among oesophageal and gastric cancer. DESIGN: Although oesophageal and gastric cancer surgery is centralised in the Netherlands, the disease is often diagnosed in hospitals that do not perform this procedure. METHOD: Patients with potentially curable oesophageal or gastric cancer tumours diagnosed between 2005 and 2013 were selected from the Netherlands Cancer Registry. The probability to undergo curative treatment was examined for each hospital of diagnosis after adjustment for case-mix. Effects of variation in probability of undergoing curative treatment among these hospitals on survival were investigated Cox regression. RESULTS: All 13,017 patients with potentially curable oesophageal and 5,620 patients with potentially curable gastric cancer, diagnosed in 91 hospitals, were included. After adjustment, the proportion of oesophageal cancer patients receiving curative treatment ranged from 50% to 82% and from 48% to 78% for patients with gastric cancer in 2010-2013, depending on hospital of diagnosis (both P < 0.001). Furthermore, patients diagnosed in hospitals with a low probability of undergoing curative treatment had a worse overall survival in the period 2010-2013 (oesophageal cancer hazard ratio (HR): 1,15; 95%-CI: 1,07-1,24; gastric cancer HR: 1,21; 95%-CI: 1,04-1,41). CONCLUSION: The variation in probability of undergoing potentially curative treatment for oesophageal and gastric cancer between hospitals of diagnosis and its impact on survival indicates that treatment decision-making for these patients may be improved. Regional expert multidisciplinary team meetings in this field may improve the selection of patients for curative treatment.

This metabolic disease is characterised by body odour resembling fish. CASE DESCRIPTION: A 7-year-old boy was referred with abnormal body odour, which his mother described as resembling fish. This odour caused mainly social problems. Because of the characteristic odour trimethylaminuria was considered. Further metabolic investigations showed a high concentration of trimethylamine in the urine, consistent with this diagnosis. CONCLUSION: Trimethylaminuria is rare, but due to its psychological and social impact it is important that it is recognised. Although bad body odour is seldom a manifestation of a metabolic disease, it should always be included in the differential diagnosis.

Quality becomes a leading principle. Transparency will lead to better care in hospitals that compare their results with each other. Making quality visible together creates the group pressure this requires. Professional and patient organisations cannot stay behind when reducing costs. Physicians and patients should contribute to providing cheaper care. Concentrating care also helps to reduce costs. Hospital data will have to be processed to help patients select a treatment. This requires substantial investments in ICT. More attention should be given to the entire care chain. In science, the focus should shift from evidence-based to quality-based medicine. 'Value-based healthcare' turns the medical world on its head and requires time, patience and adjustment. This will repay itself in better quality, lower costs, higher satisfaction and more control for patients when making decisions about their treatment. PMID- 29600924 TI - [Power, you can never have enough of it]. AB - - In randomised trials on the effects of a medical treatment, the power of the trial corresponds to the conditional probability that the conclusion of the trial will be that the treatment is effective, given a certain treatment effect.- The time to consider the power of a trial is before conducting the study, to ensure that the design of the trial is such that there is a reasonable chance of demonstrating a clinically relevant effect. PMID- 29600925 TI - ? AB - A 7-year-old boy was referred to the paediatric clinic with a swollen cheek since one day. Intraoral examination revealed erythematous and swollen gingivae in the right upper quadrant. The consulted maxillofacial surgeon diagnosed him with a canine fossa abscess. The patient recovered quickly after incision and drainage, followed by antibiotic therapy.

AB - This article discusses the diagnosis and management of two patients with cerebral fat embolism syndrome after traumatic femoral fractures. Fat embolism syndrome is a condition which is caused by fat globules in the systemic circulation; it most often occurs in patients with femoral fractures. Patients develop systemic dysfunction, particularly a triad of a petechial rash, respiratory and neurological dysfunction. The syndrome is characterized by a diverse clinical presentation which often necessitates a wide differential diagnosis. The pathogenesis of fat embolism syndrome has not yet been fully elucidated. Although it has been a formally recognised clinical diagnosis for years, new diagnostic imaging capabilities have provided a shift towards a visualisable disorder. Presently, there is no clear evidence and indication for dedicated treatment and therefore supportive measures remain the only treatment modality.

AB - Acute lobar nephritis (ALN) is a focal interstitial bacterial infection of the renal parenchyma. ALN is described as a midpoint between an acute pyelonephritis and renal abscess. ALN is underdiagnosed in children due to both non-specific symptoms and negative urinalysis/bacteriuria laboratory findings. The gold standard for diagnosis of ALN is CT scanning, however MRI can be considered to avoid radiation exposure. Diagnosing ALN is relevant, because it requires prolonged antibiotic treatment. Insufficient antibiotic treatment could cause renal scarring and subsequent hypertension or renal failure. Outpatient follow-up is indicated to exclude congenital urogenital abnormalities. We describe two paediatric patients with acute abdominal pain and fever who were suspected to have appendicitis (appendix not visualised by ultrasonography), but eventually were diagnosed with ALN and a renal abscess (despite absence of pyuria). These reports serve to highlight the issues around the recognition and diagnosis of ALN in children, and the need for clinicians to be mindful of this condition. PMID- 29600928 TI - [Bacteriophages in the battle against multidrug resistant bacteria]. AB - Bacteriophages are viruses that infect bacteria. They are highly specific for a bacterial species. The so-called 'lytic phages' can lyse bacteria when they infect them; these phages can be used to treat bacterial infections. Despite a century of experience with phage therapy, the evidence for clinical efficacy is limited. Side effects are generally considered to be mild. The selection, preparation and administration of phages for therapy is laborious, and investigations into the clinical benefits are not easy. More research is needed, also in the face of the increasing antimicrobial resistance. PMID- 29600929 TI - [Paediatric epilepsy surgery; the earlier, the better]. AB - The first randomised trial of paediatric epilepsy surgery demonstrated what was already known for decades among physicians of children with refractory epilepsy: surgical treatment is a highly successful treatment option with superior efficacy compared to ongoing drug treatment in well-selected surgical candidates. The lack of equipoise and the design of the trial - in which half of the children had to wait for one year before being offered surgery - raises questions about its ethical justification. A shorter duration of epilepsy predicts better cognitive and seizure outcomes after surgery. Surgical risks are low, seizure-freedom rates are high for specific pathologies, and the chance of spontaneous permanent remission is low in children with focal lesional epilepsy. These children should be referred for presurgical evaluation early after diagnosis. Benefits of surgery may outweigh the limited surgical risks when the lesion is located outside eloquent brain areas, even when seizures are well controlled with antiepileptic drugs. PMID- 29600930 TI - [Report of the Dutch National Health Council on chronic fatigue syndrome]. AB - In our opinion, the recent report of the Dutch National Health Council on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) lacks balance: it is very critical on the quality of evidence regarding behavioural interventions, but lacks a critical attitude regarding the presumed somatic components of the disorder. Without solid evidence, the report coins ME/CFS as a severe multisystem disease, and it embraces the diagnostic criteria of the American Institute of Medicine. We underscore the remarks in the report that physicians should not be reluctant to make diagnosis in patients with the disorder, and that these patients should be approached with empathy and respect. Regarding a future research programme, there is need for a well-designed research agenda. PMID- 29600931 TI - Effects of biologic disease-modifying anti-rheumatic drugs on the radiographic progression of rheumatoid arthritis: a systematic literature review. AB - OBJECTIVES: To evaluate the effect of biologic disease-modifying anti-rheumatic drugs (bDMARDs) on radiographic progression in patients with rheumatoid arthritis (RA). METHODS: A systematic review of electronic databases and conference proceedings was conducted through January 2015, to identify randomised controlled trials (RCTs) and observational studies that assessed the impact of bDMARDs [+/- conventional synthetic DMARDs (csDMARDs), mainly methotrexate (MTX)], versus csDMARDs alone, on radiographic progression in patients with RA. RESULTS: Following screening of >5000 records, 104 publications covering 63 studies were included. Of 34 RCTs in patients with early, active (n=13) or established RA (n=21) [abatacept (1, 2); adalimumab (4, 2); certolizumab pegol (1, 4); etanercept (3, 3); golimumab (1, 4); infliximab (1, 1); rituximab (1, 1); tocilizumab (1, 5)], combination therapy with a bDMARD and MTX had a significantly greater effect than placebo or MTX alone, in inhibiting radiographic progression. This included patients previously unresponsive, or who responded incompletely, to MTX treatment alone, and was supported by data from observational studies. Findings from a smaller subset of these and other RCTs supported superiority of combination therapy over bDMARD monotherapy, and bDMARD monotherapy over MTX, in slowing radiographic progression. CONCLUSIONS: There is evidence from RCTs with a range of bDMARDs that improvement in radiographic outcomes for patients with early or established RA, when used in combination with MTX and to a lesser extent as monotherapy, are significantly greater than MTX alone. There was no evidence of a difference between bDMARDs on inhibition of radiographic progression.

AB - OBJECTIVES: In 2004 and 1999, respectively, recent-onset rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) cohorts were initiated; the 36 item Medical Outcome Study Short-Form survey (SF-36) was applied beginning from enrolment. The objectives were to compare the SF-36v2 scores between patients from both cohorts who achieved sustained remission and to define the role of disease diagnosis as associated to SF-36v2 normative data in remission patients. METHODS: Sustained remission was considered when RA and SLE patients achieved at least 12 months of continuous follow-up with either SLE disease activity index 2000 update =0 or Disease Activity Score (28 joints) <=2.4, respectively. Up to December 2015, data from 172 RA patients and 211 SLE patients were reviewed. SF 36v2 scores were available for the totality of remission assessments. Logistic regression models were used to investigate factors associated with normative SF 36v2. Written informed consent was obtained from all patients. RESULTS: A higher proportion of patients achieved sustained remission sooner in the RA cohort than in the SLE cohort, 58% vs. 30.6% of the patients, after 30.8+/-23.9 vs. 59.4+/ 37.5 months, respectively, p<=0.001. At sustained remission, RA patients scored better than SLE patients in 6 out of 8 domains of the SF-36v2 and the physical health component summary (PHCS); the opposite figure was true for the mental component. Age (beta: 1.06, 95% CI: 1.02-1.1, p=0.03) and SLE diagnosis (beta: 9.64, 95% CI: 3.61-25.75, p<=0.001) were predictors of not achieving normative PHCS. CONCLUSIONS: RA patients in sustained remission achieved better quality of life than SLE patients.

PMID- 29600936 TI - Association between primary Sjogren's syndrome, cardiovascular and cerebrovascular disease: a systematic review and meta-analysis. AB - OBJECTIVES: Acute systemic inflammation and chronic systemic vasculitis are associated with endothelial dysfunction and atherosclerotic plaque formation. Studies on cardiovascular or cerebrovascular events in primary Sjogren's syndrome (pSS) are limited, with conflicting results. This meta-analysis aimed to explore the risk of cardiovascular and cerebrovascular disease in pSS. METHODS: A comprehensive search of the MEDLINE and EMBASE databases was performed from date of inception through August 2017. The inclusion criterion was observational studies evaluating the association between pSS and cardiovascular disease or cerebrovascular event. Outcomes are diagnosis of ischaemic heart disease, myocardial infarction, ischaemic stroke or haemorrhagic stroke. The pooled odds ratio (OR) of the cerebrovascular event or cardiovascular disease and their 95% confidence interval (CI) were calculated using a random-effect meta-analysis to compare risk between patients with pSS and controls. The between-study heterogeneity of effect-size was quantified using the Q statistic and I2. RESULTS: Data were extracted from 10 observational studies involving 165,291 subjects. Pooled result demonstrated a significant increase in risk of having cardiovascular disease or cerebrovascular event in pSS patients compared with controls (OR=1.28; 95% CI: 0.11-1.46, p value<0.01, I2=68%). Subgroup analyses showed no difference in risk for cerebrovascular event (OR=1.31; 95% CI: 0.96 1.79, p value=0.09, I2=71%), but an increased risk of cardiovascular disease (OR=1.30; 95% CI: 1.09-1.55, p value=0.003, I2=74%). CONCLUSIONS: Our study has shown an increased risk of cardiovascular or cerebrovascular disease in patients with pSS. These results support multiple studies' finding of increased arterial stiffness in patients with pSS. PMID- 29600938 TI - Detection of human T lymphotropic virus type-I bZIP factor and tax in the salivary glands of Sjogren's syndrome patients. AB - OBJECTIVES: To detect HTLV-I bZIP factor (HBZ), tax and relevant molecules in labial salivary glands (LSGs) from patients with Sjogren's syndrome (SS). METHODS: The expressions of HBZ and tax in T cell lines and LSGs were analysed by in situ hybridization (ISH) or real time PCR. The expressions of forkhead box P3 (Foxp3) and p65 in immunohistochemistry were quantified. RESULTS: After specificity of ISH probes was determined in 5 T cell lines, in LSGs from an adult T-cell leukemia (ATL) patient and 3 HTLV-I-associated myelopathy (HAM)-SS patients, both HBZ and tax signals were detected in infiltrating mononuclear cells (MNCs) and ducts, and HBZ and tax were dominantly expressed in MNCs of ATL and HAM-SS, respectively. HBZ was dominantly observed in LSGs from 8 HTLV-I asymptomatic carrier (AC)-SS patients; faint expression of HBZ was observed in LSGs from 5 HTLV-I-seronegative SS patients. No cell adhesion molecule 1(CADM1) expressed in LSGs from the ATL patient. Although Foxp3 expression was observed in LSG MNCs of all of the SS patients, the ATL patient's expression was significantly greater than that of the AC-SS (p<0.01) and HTLV-I-seronegative SS (p<0.01) patients. The Foxp3 expression was similar in ATL and HAMSS, but significantly higher in HAM-SS than AC-SS (p<0.05). p65 was expressed in LSG MNC nuclei from all SS patients and co-expressed with Foxp3. The expressions of Foxp3 in ducts differed according to HTLV-I infection. CONCLUSIONS: These results suggest that HBZ-mediated Foxp3 expression is partly associated with the pathogenesis of HTLV-I-seropositive SS. PMID- 29600939 TI - Chinese registry of rheumatoid arthritis (CREDIT): I. Introduction and prevalence of remission in Chinese patients with rheumatoid arthritis. AB - OBJECTIVES: To introduce the Chinese Registry of rhEumatoiD arthrITis (CREDIT), which is the first nationwide, multicentre, online rheumatoid arthritis (RA) registry in China, and to depict major cross-sectional data and treatment strategies of Chinese RA patients. METHODS: RA patients who fulfilled the 2010 ACR/EULAR classification criteria for rheumatoid arthritis were recruited into the registry by their rheumatologists from 144 clinical centres in China. Data, including demographics, disease characteristics, co-morbidities, treatment, and adverse reactions, were collected and documented through the predefined protocol. RESULTS: 8071 registered patients (F:M = 4.03:1) were registered up to May 2017. Mean age at symptom onset and at diagnosis was 46.15+/-14.72y and 48.68+/-14.54y, respectively. Point prevalence of remission (95% CIs) was 14.88% (14.10-15.66%), 4.23% (3.79-4.66%), 4.25% (3.81-4.69%), and 4.27% (3.83-4.72%) according to DAS28 CRP, CDAI, SDAI, and the 2011 ACR/EULAR remission criteria, respectively. 38.84% and 38.11% of treatment-naive patients (n=3262) were in moderate (3.25.1) disease activity, respectively. Among treatment-naive patients, those who were initiated on treatment with bDMARDs had higher disease activity than those who were treated with csDMARDs (p<0.05). Three months after initiating bDMARDs, 19.29% (n=38) of patients achieved remission (DAS28-CRP<2.6). CONCLUSIONS: The CREDIT registry is an effective tool for real world study of RA patients in China. By providing information for diagnosis and treatment regimen, the CREDIT registry can enhance the application of treat-to target (T2T) strategy and improve patient outcomes in China. PMID- 29600940 TI - The burden of systemic juvenile idiopathic arthritis for patients and caregivers: an international survey and retrospective chart review. AB - OBJECTIVES: To investigate the burden of systemic juvenile idiopathic arthritis (SJIA) on health-related quality of life (HRQOL) and resource use of patients and caregivers (families) on biologic therapy. METHODS: This international study assessed SJIA burden in patients on biologics, using a caregiver questionnaire and retrospective chart review. Validated measures included: Child Health Questionnaire Parent-Form 50 (CHQ-PF50), 36-Item Short-Form Health Survey (SF 36v2) and Work Productivity and Activity Impairment questionnaire: Specific Health Problem (WPAI:SHP). Caregivers completed function, treatment satisfaction and resource utilisation questions. RESULTS: Sixty-one biologic treated patients participated (12 anakinra, 25 canakinumab, 24 tocilizumab). Mean age at diagnosis and survey completion was 6.4 and 11.3 years, respectively. Mean (+/-SD: standard deviation) CHQ-PF50 physical (PhS) and psychosocial (PsS) summary scores were significantly lower in SJIA patients than a normative population (PhS: 40.0+/ 18.2 vs. 53.0+/-8.8; PsS: 46.6+/-11.3 vs. 51.2+/-9.1) as was caregivers' mean SF 36v2 mental component score (MCS; 46.2+/-10.7 vs. 50.0+/-10). Assistive devices were required by 54%; 20% required home/car alterations. According to caregivers, biologic treatment completely improved SJIA symptoms in 48% on canakinumab or tocilizumab and 32% on anakinra. Over 2 months, patients missed 2.9 school days due to SJIA (10% yearly loss). Caregivers lost 25 work days annually and 27.5 days of productivity (WPAI-SHP: mean absenteeism 10%; presenteeism 11%). Yearly SJIA travel/treatment costs averaged $1,130. CONCLUSIONS: SJIA patients on biologic therapy experience HRQOL impairment, caregivers' mental well-being suffers and productivity losses and expenses are incurred. Therapeutic interventions that reduce the burden of SJIA are required.

PMID- 29600942 TI - Serum Epstein-Barr virus DNA, detected by droplet digital PCR, correlates with disease activity in patients with rheumatoid arthritis. AB - OBJECTIVES: To study the prevalence of asymptomatic activation of Epstein-Barr virus (EBV) in patients with rheumatoid arthritis (RA) and to analyse the correlation of serum EBV DNA with the disease activity. METHODS: The level of EBV DNA was determined by droplet digital PCR assay from the serum of 46 DMARD naive early RA (ERA) and 22 chronic RA (CRA)-patients at study onset. Follow-up samples from 31 ERA and 16 CRA patients were obtained after starting or modifying the anti-rheumatic treatment. EBV DNA was also measured from 33 healthy controls and 9 patients with adult onset Still's disease (AOSD). Disease activity was assessed by the disease activity score (DAS28). RESULTS: At baseline, EBV DNA was detected in the serum of 7 of the 46 ERA patients all of whom had moderate or high disease activity. In the follow-up samples, 11 of 31 patients were EBV DNA positive. At baseline EBV positive patients had significantly higher disease activity (p=0.036) and the concentration of EBV DNA correlated significantly with DAS28 (rs=0.333, p=0.024). EBV DNA was detected in 3 of 22 CRA patients at study onset and in 8 of 16 in the follow-up samples. At follow-up EBV positive patients had significantly higher DAS28 (p=0.027) and the concentration of EBV DNA correlated significantly with DAS28 (rs=0.724, p=0.002). Only one of the healthy controls and none of the AOSD patients were positive for EBV DNA. CONCLUSIONS: Active RA is associated with a lytic EBV infection which may have a role in the pathogenesis of RA. PMID- 29600943 TI - Silent arterial inflammation during the apparent remission state of Takayasu's arteritis. What do cytokines tell us? AB - OBJECTIVES: To evaluate serum cytokines as biomarkers of smoldering disease activity in patients with Takayasu's arteritis (TAK) in remission. METHODS: Thirty-four TAK patients with stable disease during the last 6 months and 22 healthy controls (HC) were included in a cross-sectional study. Serum levels of pro-inflammatory, anti-inflammatory, Th1, Th2, Th9, Th17 and Th22 cytokines were measured by the multiplex technique. RESULTS: No significant differences regarding serum cytokine levels were found between TAK patients and HC. Serum TNF alpha, IL-17F, IL-21 and IL-23 were higher in patients presenting angiographic type V than in those presenting other angiographic types. Serum IL-17E, IL-17F, IL-22 and IL-23 were higher in TAK patients with previous ischaemic events compared with those without previous ischaemia. No differences in serum cytokines were observed between TAK patients with and without aneurysmal disease in the aorta or among TAK patients without therapy, those under immunosuppressive agents and patients on biological therapy. Independent associations were found regarding angiographic type V and higher serum levels of IL-4, IL-6, IL17A, IL-17E, IL-17F, IL-21, IL-22 and IL-23. Previous ischaemic events were independently associated with higher serum IL-4, IL-17E, IL-22 and IL-23. Daily prednisone dose had an inverse association with lower serum IL-4, IL6, IL-17A, IL-17E, IL-22 and IL-23. The simultaneous use of immunosuppressive and biological agents led to lower serum IL-4, IL-17E and IL-23 levels. CONCLUSIONS: A smoldering inflammatory response with predominantly cytokines involved in Th17 response seems to be ongoing in TAK patients in remission with extensive disease or with previous ischaemic events. PMID- 29600944 TI - Investigation of serum biomarkers in primary gout patients using iTRAQ-based screening. AB - OBJECTIVES: Primary gout is a major disease that affects human health; however, its pathogenesis is not well known. The purpose of this study was to identify biomarkers to explore the underlying mechanisms of primary gout. METHODS: We used the isobaric tags for relative and absolute quantitation (iTRAQ) technique combined with liquid chromatography-tandem mass spectrometry to screen differentially expressed proteins between gout patients and controls. We also identified proteins potentially involved in gout pathogenesis by analysing biological processes, cellular components, molecular functions, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and protein-protein interactions. We further verified some samples using enzyme-linked immunosorbent assay (ELISA). Statistical analyses were carried out using SPSS v. 20.0 and ROC (receiver operating characterstic) curve analyses were carried out using Medcalc software. Two-sided p-values <0.05 were deemed to be statistically significant for all analyses. RESULTS: We identified 95 differentially expressed proteins (50 up-regulated and 45 down-regulated), and selected nine proteins (alpha-enolase (ENOA), glyceraldehyde-3-phosphate dehydrogenase (G3P), complement component C9 (CO9), profilin-1 (PROF1), lipopolysaccharide-binding protein (LBP), tubulin beta 4A chain (TBB4A), phosphoglycerate kinase (PGK1), glucose-6-phosphate isomerase (G6PI), and transketolase (TKT)) for verification. This showed that the level of TBB4A was significantly higher in primary gout than in controls (p=0.023). CONCLUSIONS: iTRAQ technology was useful in the selection of differentially expressed proteins from proteomes, and provides a strong theoretical basis for the study of biomarkers and mechanisms in primary gout. In addition, TBB4A protein may be associated with primary gout. PMID- 29600945 TI - Lofgren syndrome as secondary autoimmune disease in a patient with B-cell depletion following rituximab treatment.

AB - OBJECTIVES: Physical activity is an important part of children's health and social development. Juvenile idiopathic arthritis (JIA) can lead to decreased physical activity and quality of life. This study characterised clinical aspects, physical activity rates, obesity, and screen time in a group of JIA patients. METHODS: Ninety-seven JIA patients in the Paediatric Rheumatology Clinic at Meir Medical Center were evaluated over a 6-month period and compared by statistical methods to 98 age-matched healthy controls. Information on disease activity, type and amount of physical activity (using the Modified Godin Leisure-Time Exercise Questionnaire), and daily screen time hours were collected. RESULTS: Among the JIA patients, 56% had oligoarthritis, 22% polyarthritis and 17% systemic disease. Disease activity among all JIA sub-groups was low (average of 1.7/10), two-thirds of patients had disease activity lower than 3, only 4% over 5, and 56% were in clinical remission. Obesity rates in the patient and control groups were 21.5% and 19.4%, respectively. Physical activity levels were similar in both groups. Age at onset of disease and physical activity rate were negatively correlated (r= 0.288, p=0.004). Total weekly leisure activity of the control group was higher (46.9 vs. 38.4 hours, respectively), while daily screen time was similar (3.2 vs. 2.9 hours, respectively). CONCLUSIONS: Physical activity, obesity rates and screen time hours were similar between JIA patients and controls. This lack of difference could be attributed to clinical remission following early, aggressive, treat-to-target therapy. PMID- 29600948 TI - Intraarticular infliximab therapy in patients with juvenile idiopathic arthritis: the role of musculoskeletal ultrasound and disease activity scores in monitoring therapy response. AB - OBJECTIVES: Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children, with heterogeneous clinical features. Although therapeutic options are wide and in the majority of children symptoms improve with the combination of non-steroidal anti-inflammatory and disease-modifying drugs, there are a number of patients who do not respond to conventional therapy and who do not meet the criteria for systemic biologics, namely anti TNF-alpha. Those patients are potential candidates for intraarticular therapy with biologics and in this report we present the results of intra-articular infliximab treatment in a series of patients diagnosed with oligoarticular subtype of JIA. METHODS: Twenty patients (30 joints) were treated with intraarticular infliximab and monitored by power Doppler musculoskeletal ultrasound according to the OMERACT and Juvenile Arthritis Disease Activity Score (JADAS 10) before intraarticular application and during the follow-up period of 18 months (0, 1, 12, 18 months). RESULTS: The results showed statistically significant improvement in PD-MSUS measures and JADAS in both B mode and power Doppler mode scores (p<0.001, p<0.001, respectively) in patients treated with i.a. infliximab with persistent response in fifteen patients. The JADAS score, as well as the ultrasound scores, were significantly reduced during the follow-up period. CONCLUSIONS: This study showed promising results, good safety and potential for the clinical benefit of intraarticular infliximab treatment in a selected group of patients with oligoarticular subtype of JIA. PMID- 29600949 TI - Clinical remission in rheumatoid arthritis and psoriatic arthritis. AB - It is currently recognised that remission can be an achievable target for several rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients by a treat-to target approach. For RA different remission criteria have been proposed, depending on the disease activity scores used, on the importance given to the inclusion of patients' perspective into the definition of remission, and on their applicability in clinical practice, that generate highly different remission rates. Conversely, for PsA, remission is still insufficiently defined and represents a partially unmet need. For both conditions, several first- and second line treatment strategies are now available - disease-modifying anti-rheumatic drugs (DMARDs) of synthetic and biologic origin - that make the achievement of remission or at least low/minimal disease activity a realistic goal. This paper is a narrative review of the different criteria of remission, in the light of the available treatment strategies for RA and PsA, and in the attempt to provide rheumatologists an opportunity to improve the outcome to the greatest extent possible in their clinical practice.

AB - OBJECTIVES: We aimed to assess the diagnostic accuracy of salivary gland ultrasonography (SGUS) as a single test for the detection of primary Sjogren's syndrome (pSS) and examine the prognostic factors for severe structural damage of the salivary glands based on SGUS score. METHODS: Patients with pSS (n=94) and idiopathic sicca syndrome (n=44) were evaluated using the SGUS 0-48 scoring system, which comprises five parameters: parenchymal echogenicity, homogeneity, hypoechoic areas, hyperechogenic reflections, and clearness of posterior borders. The salivary gland volume and intraglandular power Doppler signal (PDS) were also assessed. A multivariate linear regression analysis was performed to determine the factors associated with SGUS score. RESULTS: Patients with pSS showed a significantly higher SGUS score than controls [median (IQR): 24.5 (13.0) vs 6 (3.75), p<0.001]. An SGUS cut-off of >=14 had a sensitivity of 80.9% and a specificity of 95.5% for the diagnosis of pSS. There were no significant differences in the measured volumes and PDS between pSS patients and controls. The SGUS score correlated with unstimulated salivary flow rate (USFR), serum rheumatoid factor and IgG. Double seropositivity with anti-Ro/SS-A and anti-La/SS B (beta=6.060, p=0.001) and USFR (beta=-1.913, p<0.001) were independently associated with the SGUS score. CONCLUSIONS: The SGUS scoring system is a valuable diagnostic method for pSS. Double seropositivity of anti-Ro/SS-A and La/SS-B along with USFR were independent predictive factors for structural damage of the salivary glands. PMID- 29600951 TI - Linear and Nonlinear Dynamics of Heart Rate Variability are Correlated with Purpose in Life and Degree of Optimism in Anxiety Disorder Patients. AB - Although heart rate variability (HRV) may be a crucial marker of mental health, how it is related to positive psychological factors (i.e. attitude to life and positive thinking) is largely unknown. Here we investigated the correlation of HRV linear and nonlinear dynamics with psychological scales that measured degree of optimism and happiness in patients with anxiety disorders. Results showed that low- to high-frequency HRV ratio (LF/HF) was increased and the HRV HF parameter was decreased in subjects who were more optimistic and who felt happier in daily living. Nonlinear analysis also showed that HRV dispersion and regulation were significantly correlated with the subjects' optimism and purpose in life. Our findings showed that HRV properties might be related to degree of optimistic perspectives on life and suggests that HRV markers of autonomic nervous system function could reflect positive human mind states. PMID- 29600952 TI - Generalized Multiplicative Model for Assessing Outcome in Psychotherapy: Subjective Well-Being. AB - The study presents the performance of generalized multiplicative model (GMultM) for assessing outcome in psychotherapy. GMultM is a flexible nonlinear regression method which is able to predict the impact of subjects' psychological variables (common factors such as inner directedness, time competence, sociotropy, and perfectionism, locus of control, body dissatisfaction, neuroticism, and alexithymia) as well as their changes on the outcome of psychotherapy. This nonlinear regression model including interaction effects among predictors has a higher explanatory power to predict treatment outcome, compared to any linear model. Also, GMultMs are accurate and easily interpretable models, compared to complex models such as, for example, based on nonlinear dynamics, complexity, stochastic optimization control theories, etc. A case study of rhythmic movement therapy (RMT) for increasing the level of subjective well-being (SWB) is presented. Results revealed that: (a) the GMultM not only predicts the current levels of SWB satisfactorily but also allows obtaining the partial response functions of psychological predictors of SWB directly as a result of estimation of model's parameters; (b) GMultM predicts the changes in SWB after RMT intervention in each participant satisfactorily and thus can be applied as the individualized assessment tool for psychotherapy's outcome. PMID- 29600953 TI - Multi-day Patterns around Taking Action in Intimate Partner Violence. AB - This study was to determine the multi-day relationships among stressors, need and taking action (seeking counseling, taking legal action, leaving) by women in violent relationships. Women with recent husband-to-wife abuse but not at high risk for life-threatening violence were recruited from six primary care clinics and asked to complete a daily description of the previous day's violence, need for-action, and stressors using Interactive Voice Response via telephone for 8 weeks. Taking action (seeking counseling, taking legal action, leaving) was determined via weekly telephone contacts. To identify day-to-day recurrent strings, we used orbital decomposition, limiting time series to 29 women who took action during the study. Multi-day patterns were not common in taking action and are unrelated to violence. Only one 5-day string involving seeking counseling was identified in which women felt a lack of control. While taking legal action was part of five 5-days strings, each string consisted of one day of taking legal action within four days of no need-for-action, violence or stalking. Finally, one 4-day string that began with leaving coupled with spouse's excessive alcohol intake but no violence was noted. Hence, decisions to take action in violent relationships are not typically multi-day decisions linked to violence, but rather sudden events triggered by loss of control, his alcohol intake or unique situational factors. PMID- 29600954 TI - On the Pervasiveness of Long Range Memory Processes in Daily High School Attendance Rates. AB - Few educational researchers or practitioners would question that high school attendance is an important mediator in the causal network that is used to explain academic achievement, yet attendance remains under-researched. The New York City Department of Education (NYCDOE) has created an opportunity to examine the longitudinal trends and dependencies in daily attendance rates as it created a repository of daily attendance rates for all its schools, starting in 2004. The present analysis examines the dynamical patterns in daily attendance rates over a ten-year period (Sept. 2004 - June 2014) in six small high schools and ten large ones. As was done in previous work, this analysis systematically distinguishes short range, seasonal and long range dependencies in the data using time series analysis. Seasonal cycles are predictable (here, fluctuation by days of the week), the long range dependencies indicate cycles that are unpredictable, suggestive of more complex dynamical processes, such as self-similarity, self organized criticality and scale invariance, features that are difficult to detect by school building personnel, but are important aspects of the systems' behavior. Seasonal cycles were found in three of the nine large schools and in all six small ones. Significant long range dependencies (Hurst exponent) were found in all large schools and all but one of the small ones. The pervasiveness of the long range processes over and above the seasonal cycles is striking, and may suggest an adaptability of these systems to fluctuations in the exogenous processes that find their expression in daily attendance behavior (e.g., parental involvement). However, this latter interpretation is in need of further empirical support. PMID- 29600955 TI - Finding Fractal Networks in Literature. AB - This paper is about how fractal connections between words can be identified and hidden fractal word-networks uncovered in corpus texts. The basis for this 'search-and-find' procedure is the hypothesis Complexity Connections in Corpuses (CCIC) consisting of four separate sub-hypotheses, each the basis of a procedure for uncovering a special part of such networks. The validity and applicability of CCIC are demonstrated by showing that each sub-hypothesis holds good for twenty four masterpieces, selected from the world's great library of novels and treatises. And the hidden structure is 'developed' by means of our computer program ZIPPF. It turns out that this hidden structure is similar for all investigated corpus texts, a fact which, in our thinking, supports the idea that the hidden word-network renders us a glimpse of working processes used by the brain machinery to produce text. The conclusion is that CCIC provides tools for linguistic research, is a supplement to linguistic networks theory, and opens up for, inter alia fractal-mathematical, studies of high-level brain/mind activity because it follows from CCIC that human verbal thinking is fractal.

AB - Inheritance of the E4 allele of the apolipoprotein E gene (APOE4) substantially increases the risk of developing late-onset Alzheimer disease (AD). A large body of evidence has firmly established a role for apoE in modulating the risk of developing the amyloid plaque pathology that is pathognomonic for AD. In this issue of the JCI, Liao and colleagues discovered that antibodies against a nonlipidated form of apoE4 are highly effective in delaying the deposition of amyloid beta (Abeta) peptides in mouse models of AD pathology. Using a combination of passive immunization and viral-mediated expression of recombinant antibodies, the authors show that Fc receptor-mediated clearance of the nonlipidated apoE4 was critical in delaying Abeta deposition. Collectively, this study identifies a new therapeutic target that could be exploited to prevent, or possibly reverse, the Abeta pathology of AD. PMID- 29600961 TI - Targeting of nonlipidated, aggregated apoE with antibodies inhibits amyloid accumulation. AB - The apolipoprotein E E4 allele of the APOE gene is the strongest genetic factor for late-onset Alzheimer disease (LOAD). There is compelling evidence that apoE influences Alzheimer disease (AD) in large part by affecting amyloid beta (Abeta) aggregation and clearance; however, the molecular mechanism underlying these findings remains largely unknown. Herein, we tested whether anti-human apoE antibodies can decrease Abeta pathology in mice producing both human Abeta and apoE4, and investigated the mechanism underlying these effects. We utilized APPPS1-21 mice crossed to apoE4-knockin mice expressing human apoE4 (APPPS1 21/APOE4). We discovered an anti-human apoE antibody, anti-human apoE 4 (HAE-4), that specifically recognizes human apoE4 and apoE3 and preferentially binds nonlipidated, aggregated apoE over the lipidated apoE found in circulation. HAE-4 also binds to apoE in amyloid plaques in unfixed brain sections and in living APPPS1-21/APOE4 mice. When delivered centrally or by peripheral injection, HAE-4 reduced Abeta deposition in APPPS1-21/APOE4 mice. Using adeno-associated virus to express 2 different full-length anti-apoE antibodies in the brain, we found that HAE antibodies decreased amyloid accumulation, which was dependent on Fcgamma receptor function. These data support the hypothesis that a primary mechanism for apoE-mediated plaque formation may be a result of apoE aggregation, as preferentially targeting apoE aggregates with therapeutic antibodies reduces Abeta pathology and may represent a selective approach to treat AD.

PMID- 29600966 TI - Asymmetric dimethylarginine as a useful risk marker of radial artery calcification in patients with advanced kidney disease. AB - INTRODUCTION Medial arterial calcification is common in patients with chronic kidney disease (CKD) and is considered a risk factor for morbidity and mortality. OBJECTIVES We aimed to evaluate the correlation between asymmetric dimethylarginine (ADMA) levels, radial artery calcification, and common carotid artery intima-media thickness (CCA-IMT). PATIENTS AND METHODS The study included 51 patients with CKD, in whom an arteriovenous fistula for hemodialysis access was created to collect radial artery samples for a histological examination, and 33 healthy volunteers, in whom the reference concentrations of ADMA were assessed. The concentrations of creatinine, albumin, calcium, phosphate, fibroblast growth factor 23, osteoprotegerin (OPG), osteopontin (OPN), osteocalcin, secreted protein acidic and rich in cysteine, interleukin 6, interleukin 18, pentraxin 3, stromal cell-derived factor 1alpha (SDF1alpha), thrombomodulin, soluble tumor necrosis factor receptor II (sTNFRII), and matrix metalloproteinase 2 (MMP-2) were determined. Radial artery fragments were stained for calcifications using alizarin red. The CCA-IMT was assessed by ultrasonography. RESULTS Patients with CKD had higher ADMA levels than controls. Patients with ADMA levels above the median were older, had higher levels of phosphate, fibroblast growth factor 23, OPG, OPN, PTX3, sTNFRII, MMP-2, thrombomodulin, and they had more atherosclerotic plaques in the carotid artery. In multiple regression, log-transformed (log)sTNFRII, MMP-2, and SDF1alpha levels were independent predictors of log(ADMA). Patients with calcifications had higher ADMA levels. A similar correlation was observed between SDF1alpha and alizarin red staining grades 1 to 3. In logistic regression, ADMA levels positively predicted the presence of calcifications independently of age, hemodialysis status, Framingham risk score, and PTX3. CONCLUSIONS Circulating ADMA levels indicate medial arterial calcification in patients with CKD. PMID- 29600967 TI - Ventricular fibrillation induced by radiofrequency energy delivery for premature ventricular contractions arising from the right ventricular outflow tract: is implantablecardioverterdefibrillator indicated? AB - INTRODUCTION Inadvertently induced ventricular fibrillation (VF) by radiofrequency (RF) energy delivery for premature ventricular complexes (PVCs) is a rare phenomenon; nevertheless, it is crucial to assess long-term risk of sudden cardiac death in these patients. OBJECTIVES The aim of our study was to define the long-term prognosis in patients with normal ejection fraction (EF), in whom VF was inadvertently induced by RF energy application during ablation of symptomatic idiopathic PVCs originating from the right ventricular outflow tract (RVOT). PATIENTS AND METHODS Among over 20 000 RF catheter ablations performed at 5 tertiary centers (2008-2016), 6 patients (5 men) had VF induced by RF application to the RVOT. The mean (SD) age of patients was 35.2 (16.8) years. All patients had normal EF (>=60%). We analyzed the risk of malignant ventricular arrhythmias and assessed heart function during follow-up. RESULTS After ablation, baseline contrast-enhanced magnetic resonance imaging was performed in 4 of the 6 patients; no area of late gadolinium enhancement was observed. One patient received an implantable cardioverter-defibrillator (ICD). Exercise tests revealed only rare PVCs. All patients completedthe follow-up (mean [SD] duration of follow-up, 64.0 [34.9] months). All patients were alive, with no cases of syncope, documented ventricular tachycardia, or VF. The patient with an ICD received 2 inappropriate high-voltage therapies. CONCLUSIONS Patients with inadvertently induced VF via RF energy application during ablation of PVCs from the RVOT, who have normal left ventricular function and no electrocardiography abnormalities have good prognosis and low VF risk during long-term follow-up. Therefore, ICD placement seems to be not indicated for these patients. PMID- 29600968 TI - Tumor-induced hypophosphatemic osteomalacia as a rare cause of bone pain.

AB - AIM: To determine whether the structural and functional diversities of naturally occurring antibodies to the Thomsen - Friedenreich (TF) antigen may be of diagnostic and prognostic value in colon cancer. MATERIALS AND METHODS: Serum samples were taken from patients with colon cancer (n = 94) and healthy controls (n = 64). The level of TF-specific antibody isotypes and their sialylation were determined using ELISA and lectin-ELISA with synthetic TF-polyacrylamide conjugate as an antigen and a sialic acid-specific Sambucus nigra agglutinin (SNA). The avidity was determined using ammonium thiocyanate as a chaotrope. The accuracy of diagnostics was evaluated using the receiver operator characteristic curve analysis and the survival analysis employing the Kaplan - Meier method. RESULTS: Compared to healthy controls, patients with colon cancer exhibited a lower level of anti-TF IgG antibodies, significantly lower ratios of TF-specific IgG/IgM and IgG/IgA, an increased SNA reactivity of anti-TF antibodies, mostly on account of IgG, and a lower avidity of TF-specific antibodies, especially their SNA-reactive subset. An increased SNA reactivity of anti-TF IgG was observed already at the early stages of cancer (p = 0.0004). The decrease of the ratio of IgG/IgM and IgG/IgA showed a good accuracy of diagnostics with about 60% sensitivity at 90% specificity. A similar potential was found for the SNA binding/IgG level index. The high level of TF-specific IgA antibodies was associated with a lower survival rate (hazard ratio = 0.34). CONCLUSION: This is the first report ever on the colon cancer-related signatures of anti-TF antibody diversity which show diagnostic potential, including in early cancer, and prognostic value. The hypersialylation of TF-specific antibodies appeared to be a common phenomenon in cancer. The signatures may be used as non-invasive antibody based markers for colon cancer. PMID- 29600974 TI - Morphological features of doxorubicin-resistant Walker 256 carcinosarcoma and response of mast cells. AB - BACKGROUND: The mechanisms of drug resistance of cancer have not been yet elucidated in details. Recently, the role of mast cells (MCs) in the development of drug resistance has been brought in the limelight. The aim of the study was to examine the morphological features of doxorubicin (DOX)-resistant Walker 256 carcinosarcoma and to assess the response of MCs and histamine content in these cells in relation to the development of resistance to DOX as well as in DOX resistant tumors. MATERIALS AND METHODS: The DOX resistance was induced by serial passages of Walker 256 carcinosarcoma in rats in the setting of DOX treatment in vivo. MCs in tumors were detected in the sections by staining with Toluidine Blue O. Histamine content in MCs stained with solution of Water Blue-Orcein was assessed by Astaldi semiquantitative method taking into account different staining intensity. RESULTS: Formation of DOX resistance in the course of serial passages of Walker 256 carcinosarcoma was accompanied by the increase in the number of MCs in tumors and histamine content. Nevertheless, in tumors with phenotype of complete DOX resistance the number of histamine-containing MCs decreased to the same level as in tumors of the original strain that are DOX sensitive. CONCLUSION: MCs are involved in formation of DOX resistance in Walker 256 carcinosarcoma. PMID- 29600975 TI - Highly activated carbon enterosorbent mediates the suppression of paraneoplastic syndrome associated with Lewis lung carcinoma in mice. AB - AIM: To investigate the effect of enterosorption on the development of paraneoplastic syndrome in mice with Lewis lung carcinoma (LLC). MATERIALS AND METHODS: The study was performed on male S57/VL6 mice with transplanted LLC. As an enterosorbent, highly activated powder fraction of HSGD was administered per os daily at a dose of 0.625 g/kg for two weeks starting from the 7th day after tumor cell transplantation. Analysis of hemo- and myelograms, morphological alterations in vital organs, the activities of catalase and superoxide dismutase, biochemical analysis of blood and quantitative analysis of hydroperoxides, malonic dialdehyde, advanced oxidation protein products was carried out by standard methods after completing the course of enterosorption. Ligand loading of blood plasma proteins was estimated by the method of differential scanning microcalorimetry. RESULTS: Administration of enterosorbent resulted in inhibition of LLC growth and in nearly 2-fold decrease of lung metastases number (p < 0.05). Activation of granulocytic line in the bone marrow with nearly 3-fold enhancement of mitotic activity took place after enterosorbent administration. Red cell lineage indices and bone marrow cellularity remained unaltered. After enterosorption session, the studied biochemical indices of peripheral blood evidenced on decreasing the endogenous intoxication and oxidative stress levels, improving the functional state of kidneys, increasing the resistance of erythrocyte membranes and lowering the ligand loading of blood plasma transport proteins. Morphological structure of kidneys and liver confirmed significant positive effect of enterosorption. The data of morphologic examination of gastric fundus, small intestine, and large bowel slides after 2-week administration of enterosorbent showed its high safety and proper evacuation from intestine. CONCLUSION: The two-week long enterosorption session in mice with LLC caused the suppression of tumor growth and metastasis, normalization of bone marrow hemopoiesis. Enterosorption exerted a positive influence on the structural morphologic indexes and regenerative potential of kidneys and liver, mitigated manifestations of oxidative stress, decreased the level of endogenous intoxication, promoted deliganding of albumin molecule and deloading of erythrocyte membranes. PMID- 29600976 TI - Impact of endostatin gene therapy on myeloid-derived suppressor cells from a metastatic renal cell carcinoma. AB - AIM: To evaluate the role of endostatin (ES) gene therapy on myeloid-derived suppressor cells (MDSC) in a metastatic model of renal cell carcinoma (RCC). MATERIALS AND METHODS: Balb/C mice bearing orthotopic Renca tumors were treated with NIH/3T3-LendSN or, as a control, with NIH/3T3-LXSN cells. At the end of in vivo experiment, plasma and tissue lung samples were collected. Plasma ES and granulocyte colony stimulating factor (G-CSF) levels were measured by ELISA and Milliplex, respectively. Quantification of CD11b+Gr-1+ cells and their subsets was performed by flow cytometry. Reactive oxygen species (ROS) production was measured in CD11b+Gr-1+ MDSC using the DCFDA marker by flow cytometry. RESULTS: Metastatic RCC (mRCC) induced expansions of CD11b+Gr-1+ MDSC and promoted accumulation of these cells and their subtypes in lymphoid organ and metastases. ES treatment promoted low G-CSF plasmatic levels which were produced by the tumor microenvironment, reflecting the reduced metastatic accumulation of CD11b+Gr-1+ MDSC in the lungs. However, the therapy was selective for granulocytic cells, thus reducing the production of ROS. CONCLUSION: These findings confirm the expansion of MDSC during metastatic progression of RCC and indicate the important role of ES in reducing MDSC and possible use of ES therapy in combined anticancer treatment.

PMID- 29600977 TI - Characterization of the cytotoxic effects of the combination of cisplatin and flavanol (-)-epicatechin on human lung cancer cell line A549. An isobolographic approach. AB - BACKGROUND: Among malignancies, lung cancer is a leading cause of death. Platinum based therapeutic compounds used to treat lung cancer have not been able to increase the survival of patients and such compounds have a high incidence of adverse and toxic effects. It has been proposed that flavonoids such as catechins may significantly reduce the risk of developing cancer, alongside with other health benefits. The aim of this work was to determine the effect of (-) epicatechin, the main flavanol found in cocoa, on the proliferation of the lung non-small cell adenocarcinoma cancer cell line A549, and to determine its effects when added simultaneously with cisplatin. MATERIALS AND METHODS: Concentration response curves for cisplatin and epicatechin were obtained, inhibitory concentrations calculated and an isobolographic analysis was then performed. RESULTS: We found that epicatechin has a concentration-dependent inhibitory effect on proliferation of tumor cells and the isobolographic analysis reveals that the effect of its combination with cisplatin is synergistic. It was also observed that epicatechin promotes cell death by apoptosis. CONCLUSIONS: Epicatechin might be considered for future studies to explore its possible use as coadjuvant in cisplatin-based treatments. PMID- 29600979 TI - A long survival of a patient with brain metastasis of unknown site of the primary tumor. AB - Eighty percent of brain metastases (BM) are diagnosed in patients with known primary site of cancer. BM of unknown primary represents a difficult diagnosis. In up to 15% of patients with BM, the site of the primary tumor will not be detected despite investigations. The prognosis of this entity is very poor. We report here a case of a long survival of a patient with brain metastasis of unknown primary. The conclusion that can be drawn is that within BM of unknown primary exist patients with a very good prognosis that must be collected and published in order to base recommendations. PMID- 29600980 TI - Mediastinal yolk sac tumor infiltrating the heart. AB - BACKGROUND: As a rare tumor, yolk sac tumor is a type of neoplasm that appears like the yolk sac, extraembryonic mesenchyme, and allantois. The mediastinum is the second most frequent area after the gonadal area. CASE REPORT: We present an extremely rare case of 15 years old boy with mediastinal yolk sac tumor. The boy came with the chief complaint of swelling of the neck and face. Computed tomography scan of the chest revealed bulky mass with a cystic component that infiltrated the heart. The diagnosis of mediastinal yolk sac tumor was made after core needle biopsy. Histopathologic analysis revealed tumor mass with solid and microcystic structure and pleomorphic nucleus within the tumor cells. Laboratory finding showed elevated serum alpha-fetoprotein level reaching more than 8000 ng/ml. Echocardiography revealed a mass in the right atrium. The patient condition was rapidly deteriorated due to his vena cava superior syndrome. Unfortunately, the patient died two days after diagnosis and we did not have the chance to do the therapy. CONCLUSION: Mediastinal yolk sac tumor is a rare malignancy that requires comprehensive management. The diagnosis should be made based on histopathological findings with the addition of thoracic computer tomography scan to assess the degree of infiltration to surrounding organ. A life threatening condition such as vena cava superior syndrome should be assessed promptly to allow for immediate treatment. PMID- 29600981 TI - Effect of cytostatic agents on expression levels of human beta-defensins-1-4 in A431 and MCF-7 cell lines. AB - : The aim of the study was to analyze an effect of cytostatic agents of different mechanism of action on expression levels of human beta-defensins-1-4 (hBD-1-4) in cultured human cancer cell lines. MATERIALS AND METHODS: Expression levels of hBD 1-4 mRNA were assessed using qPCR in human epidermoid carcinoma A431 cells and human breast adenocarcinoma MCF7 cells treated with cisplatin, methotrexate, doxorubicin or vincristine at the IC20 concentrations. RESULTS: The cytostatic agents with different mechanisms of action affected differently expression of hBDs, dependent on the cell line. Mostly, cytostatic agents suppressed significantly expression of hBDs. In contrast, vincristine caused significant up regulation of hBD-1 (12 fold, p < 0.05) and hBD-4 (2 fold, p < 0.05) in MCF7, and doxorubicin significantly enhanced expression of hBD-3 (2 fold, p < 0.05) and hBD 4 (> 10 fold, p < 0.05) in A431 cells. CONCLUSION: The results of this pilot study show that expression levels of hBD-1-4 may be altered upon treatment with cytostatic agents depending on nature of cells. PMID- 29600982 TI - Variant of rare Hermansky - Pudlak syndrome associated with granulomatous colitis: diagnostics, clinical course and treatment. AB - AIM: To study the relationship between the genotype and the phenotype in the patients with Hermansky - Pudlak syndrome (HPS) associated with granulomatous colitis; to monitor clinical course of the disease for adequate treatment, cancer surveillance and genetic counseling. MATERIALS AND METHODS: The diagnosis of HPS is established by physical examination, chest X-ray, computed tomography, endoscopic examination with biopsy, and laboratory tests, including histology, baseline laboratory blood, urine and feces tests, determination of ASCA-C and ANCA antibodies using an ELISA. Molecular genetic testing for HPS gene mutations, R702W, G908R, L1007fs and P268S mutations in NOD2 gene, and TaqI variant of the VDR gene were carried out. RESULTS: We report 2 cases of HPS from unrelated families. Both were complicated by inflammatory bowel disease with pathologic features of Crohn's disease refractory to antibiotics and corticosteroids. One patient (family 1) with Ashkenazi Jewish ancestry had pathogenic variant of the HPS-4 gene in exon 8, mutation P268S of NOD2 genes and "Tt" genotype of TaqI variant of the VDR gene. Another patient (family 2) carried two mutations P268S and G908R of NOD2 gene, and had a large paraovarian cyst diagnosed. No consistent success with the standard medical therapy, used for treating granulomatous colitis, associated with HPS, in presented cases was achieved. Patients needed surgical interventions at a young age and a long-term surveillance of the probable development of tumors and other complications. Azathioprine at 2 mg/kg/day and mesalazine 3 g/day were used with some positive effect for prevention of Crohn's disease postoperative recurrence. CONCLUSION: The occurrence of perianal lesions, the histopathological findings and the results of the molecular genetic analysis confirmed the mutations P268S and G908R of NOD2 gene in these cases suggest that HPS was truly associated with Crohn's disease variant with early onset and severe course. The search for the molecular causes of the disease in some individuals may help in the development of new therapeutic and surgical approaches, as well in the improvement of understanding of premalignant inflammatory conditions in a large bowel. PMID- 29600983 TI - Sensitivity to 4-hydroxyestradiol and DNA repair efficiency in peripheral blood lymphocytes of endometrial cancer patients. AB - BACKGROUND: The development of hormone-dependent cancers, including endometrial carcinomas, in great part may be mediated by the genotoxic effects of estrogen metabolites, among which 4-hydroxyestradiol (4OHE2) is characterized by the most prominent DNA-damaging properties. It is assumed that the individual sensitivity to the 4OHE2 may determine the predisposition to endometrial cancer (ES). AIM: To analyze the sensitivity of peripheral blood lymphocytes (PBLs) of EC patients to the 4OHE2 and to evaluate the repair efficiency of 4OHE2-induced DNA damage. MATERIALS AND METHODS: The study was performed on the PBLs of 53 EC patients and 20 healthy women. The level of DNA damage was measured using the comet assay and was expressed as % tail DNA. The DNA repair efficiency (%) was evaluated by determining the ratio between the amount of repaired DNA damage and the level of 4OHE2-induced damage that appeared after incubation of PBLs with 4OHE2. RESULTS: In PBLs of EC patients, a higher level of 4OHE2-induced DNA damage (32.0 +/- 2.2% tail DNA) and lower DNA repair efficiency (34.0 +/- 4.5%) was observed compared to PBLs of healthy women (22.3 +/- 2.3% tail DNA and 48.8 +/- 4.5%, respectively). PBLs of EC patients with deep tumor invasion of myometrium were characterized by more prominent decrease of DNA repair than those with less invasive tumor (< 1/2 of myometrium) (20.9 +/- 7.8 and 43.7 +/- 6.7%, respectively). Furthermore, lower DNA repair efficiency was detected in the PBLs of EC patients with a family history of cancer compared to this parameter in patients with sporadic tumors (20.9+/-7.8 and 47.1 +/- 5.5%, respectively). CONCLUSION: The PBLs of EC patients are characterized by increased sensitivity to the genotoxic effect of 4OHE2 and reduced repair efficiency regarding 4OHE2 induced DNA damage. A lower level of DNA repair is observed in EC patients with deep tumor myometrial invasion and a family history of cancer. PMID- 29600984 TI - Clinical implications of p53 alterations in oral cancer progression: a review from India. AB - p53 plays a central role in prevention of normal cell from the development of the malignant phenotype. Somatic alterations (mutations, loss of heterozygosity, deletions) in p53 are a hallmark of most human cancers and cause defects in normal p53 function. However, in the tumors harboring wild-type p53, there are alterations in the regulation of the p53. Thus, understanding why p53 is unable to perform its role as a tumor suppressor in these wild-type tumors is very crucial. Germ-line polymorphisms in p53 are also anticipated to cause measurable disturbance in p53 function. Over-expression as well as polymorphic variants of MDM2 might have effects on cancer development. In addition, degradation of p53 by E6 protein of high risk human papillomavirus is also suggested as one of the mechanisms which attenuate p53 responses in oral carcinogenesis. p53 has also been demonstrated to mediate cellular responses upon various DNA damaging cancer therapies, importantly, apoptosis. These responses have been implicated in an individual's ability to respond to these cancer therapies. Thus, exploring mechanisms by which normal function of p53 is affected in the comprehensive way in oral cancer might aid in the identification of tumor characteristics, prognosis and thus in the development of a new approach to treat the oral cancer. PMID- 29600985 TI - Role of components of microRNA machinery in carcinogenesis. AB - MicroRNAs (miRNAs) are a broad class of non-coding RNAs nearly 21 nucleotides length, which play crucial functions in post-transcriptional gene regulation. These molecules are associated with many developmental and cellular processes in eukaryotic organisms. Current investigation has reported major factors contributing to miRNA biogenesis and has constituted basic principles of miRNA function. More recently, it was confirmed that various miRNAs are clearly implicated in human malignancies, such as lung, breast, ovarian, bladder, colon cancer and other kinds of carcinoma. In addition, dysregulation in the miRNA machinery elements such as Dicer, Drosha, DGCR8, Argonaut, and TRBP could be involved in the progress of many tumor types. The purpose of the current review was to compile growing information besides how miRNA biogenesis and gene silencing are modified to develop cancer. PMID- 29600986 TI - Molecular-genetic models for prognosis of development of tumors of reproductive system in women with family history of cancer. AB - AIM: To develop a prognostic molecular genetic model for assessing the risk of development of benign and malignant tumors of female reproductive organs (FRO) in patients from cancer-affected families. PATIENTS AND METHODS: The work presents the data on a comprehensive clinical examination of 210 women (90 patients with FRO cancer with aggregation of tumor pathology in families, 65 patients with benign pathology of FRO from cancer-affected families, 55 women - control group of healthy women without family history of cancer). Clinical genealogical analysis, morphological examination of tumors and molecular genetic studies of genomic DNA from peripheral blood and tumors were carried out. RESULTS: It was established that in the families of patients with benign and malignant pathology of FRO, malignant tumors associated with Lynch II syndrome are observed. Based on the analysis of detected ESR-1, CYP 2D6*4 and mutations in BRCA1/2 genes in cancer patients and in patients with benign pathology, molecular genetic models have been developed to assess the individual risk of development of benign and malignant tumors of FRO. It has been established that these molecular genetic models and combinations of gene mutations and gene polymorphisms (SNP) by the intergene interaction that was analyzed, were found to be reliable in assessing the risk of benign and malignant pathology of the mammary gland and ovary. CONCLUSIONS: The model, which included the polymorphic variants of the T397C(ESR1)/CYP 2D6*4 genes was of the best predictive accuracy for the evaluation of the risk of benign tumors of the FRO (71.68%) and the highest reliability (p < 0.001). At the same time, all identified models of intergene interaction in the development of malignant pathology of FRO were reliable, prognostically significant with high reproduction and almost identical accuracy (65.00-68.23%). The obtained results indicate a high informativeness of such molecular genetic indices as the polymorphism of ESR1 and CYP 2D6*4 genes and mutations in BRCA1/2 genes to assess the risk of benign or malignant tumors of FRO in families of patients with family history of cancer. PMID- 29600987 TI - The use of optical coherence tomography angiography for detecting choroidal neovascularization, compared to standard multimodal imaging. AB - PurposeTo assess OCT angiography (OCTA) effectiveness at detecting choroidal neovascularization (CNV) in cases of suspected neovascular age related macular degeneration (nAMD), chronic central serous retinopathy (cCSR) and pathological myopia compared to FFA and how it compares to a multimodal approach (OCT, FFA and ICGA) for detecting the vascular network.MethodsThis was a retrospective observational cohort study of patients who had clinical and/or OCT findings suggestive of CNV, having further investigation with FFA, with or without ICG, and had same day OCTA using the Heidelberg Spectralis OCT2 beta angiography module. Multimodal imaging interpretation was compared to OCTA images. OCTA images were also analysed for inter-rater reliability (using kappa statistic). The diagnostic accuracy of OCTA was compared to FFA (using Cochran's Q, p<0.05). OCTA was also compared to a multimodal approach in defining a vascular network.ResultsOverall sensitivity of OCTA compared to FFA was 71% and specificity of 81% (p=0.108). Subgroup analysis for OCTA vs FFA for detecting classic nAMD/type II CNV sensitivity was 100% and specificity of 76% (p<0.05). OCTA vs FFA for detecting occult nAMD/type-I CNV sensitivity was 47% and specificity of 76%, (p=0.248). OCTA was better than FFA at defining a vascular network overall, when OCT was suspicious (59% vs 49%).ConclusionsOCTA was better at detecting classic nAMD/type II CNV compared to FFA and for defining a vascular network in nAMD compared to FFA and ICGA. It was able to aid in making the diagnosis in cases where evidence of CNV was uncertain following FFA/ICGA. PMID- 29600988 TI - Response to "Unexpected mutations after CRISPR-Cas9 editing in vivo".

PMID- 29600993 TI - Ultra-sensitive lithium niobate thermometer based on a dual-resonant whispering gallery-mode cavity. AB - We exploit the strong polarization dependence of the thermooptic coefficients in a lithium niobate whispering-gallery-mode resonator to create a self-referenced thermometer. An unprecedented temperature sensitivity of 3.0 GHz/K in the frequency difference between modes of orthogonal polarizations is demonstrated. In order to lock the lasers to the mode resonances, we use a simple intracavity phase modulation approach that provides for superbly low frequency instability. We demonstrate a record room-temperature thermometer detectivity of 40 nK with 1 s of averaging time. Simulations based on the fluctuation-dissipation theorem are performed to calculate the fundamental thermorefractive noise, showing that the detectivity could be improved with reduced laser-locking instabilities. PMID- 29600994 TI - Anomalous refraction of a low divergence monochromatic light beam in a transparent slab. AB - An exact formulation for the propagation of a monochromatic wave packet impinging on a transparent, homogeneous, isotropic, and parallel slab at oblique incidence is given. Approximate formulas are derived for low divergence light beams. These formulas show the presence of anomalous refraction phenomena at any slab thickness, including negative refraction and flat lensing effects, induced by reflection at the rear face. PMID- 29600995 TI - Three-dimensional super-resolved live cell imaging through polarized multi-angle TIRF. AB - Measuring three-dimensional nanoscale cellular structures is challenging, especially when the structure is dynamic. Owing to the informative total internal reflection fluorescence (TIRF) imaging under varied illumination angles, multi angle (MA) TIRF has been examined to offer a nanoscale axial and a subsecond temporal resolution. However, conventional MA-TIRF still performs badly in lateral resolution and fails to characterize the depth image in densely distributed regions. Here, we emphasize the lateral super-resolution in the MA TIRF, exampled by simply introducing polarization modulation into the illumination procedure. Equipped with a sparsity and accelerated proximal algorithm, we examine a more precise 3D sample structure compared with previous methods, enabling live cell imaging with a temporal resolution of 2 s and recovering high-resolution mitochondria fission and fusion processes. We also shared the recovery program, which is the first open-source recovery code for MA TIRF, to the best of our knowledge. PMID- 29600996 TI - Tunable light absorbance by exciting the plasmonic gap mode for refractive index sensing. AB - The tunable and narrowband optical response from the surface plasmon resonances usually requires periodic metal nanostructures; however, it is usually expensive and challenging to construct such macroscale and defect-free devices. Herein, we make it possible to obtain a characteristic and sharp absorbance via exciting the plasmonic gap mode, which can be obtained in a large-area sample prepared with relatively low cost. The resonant wavelength can be tuned via changing the bottom facet area of the top structured metal or the spacer thickness. Furthermore, we design the hexagonal arrangement gold microholes atop the gold continuous film with a spacer, which possesses a sharp reflectance dip from the intense plasmonic gap mode. Numerical calculations show that the resonant wavelength is linearly changed with the varying environmental refractive index (RI). The sensitivity is up to ~1287 nm per RI unit, and the figure of merit for an RI sensor is over 300. PMID- 29600997 TI - High-efficiency ultrafast Tm-doped fiber amplifier based on resonant pumping. AB - We demonstrated a high-efficiency ultrafast Tm-doped fiber amplifier based on a resonant pumping technique. A continuous-wave fiber laser at 1940 nm was employed as the pump laser. The slope efficiency of the resonantly pumped pulsed Tm-doped fiber amplifier reached 87% with respect to the launched pump power. The maximum average output power reached 40 W when the launched pump power was 53 W. The repetition rate and the pulse duration of the output pulses from a fiber amplifier were 248 MHz and 129 ps, respectively. The corresponding peak power was 1.25 kW, and the pulse energy was 161.3 nJ. To the best of our knowledge, this is the first demonstration of a resonant pumping enabled high-power high-efficiency ultrafast fiber laser operating at a 2 MUm band. PMID- 29600998 TI - Mode measurement of few-mode fibers by mode-frequency mapping. AB - Since few-mode fibers (FMFs) have great potential as the new transmission media for optical communications, the ability to distinguish different fiber modes is essential. Most of the traditional schemes do not yield phase information, or are limited by beam size and mechanical requirements. Here, a method is presented to analyze the mode distribution of FMFs. The fiber modes are mapped to different frequencies by using dynamic spatial phase masks. The complex amplitudes at these frequencies indicate the amplitudes and phases of the fiber modes. The method can extract not only the amplitude distribution, but also the phase distribution of the fiber modes, and no other assisted light is needed. PMID- 29600999 TI - Polarization-controlled orbital angular momentum switching in nonlinear wave mixing. AB - We demonstrate polarization-controlled switching of the orbital angular momentum (OAM) transfer in nonlinear wave mixing. By adjusting the input beam geometry, we are able to produce a three-channel orbital OAM, with arbitrary topological charges simultaneously generated and spatially resolved in the second-harmonic wavelength. The use of path and polarization degrees of freedom allows nearly perfect optical switching between different OAM operations. These results are supported by a theoretical model showing very good agreement with the experiments. PMID- 29601000 TI - Fiber fuse in chalcogenide photonic crystal fibers. AB - We observe fiber fuse in tapered GeAsSe photonic crystal fibers (PCF) at around 7 MW/cm2 of intra-core intensity. Vertically cleaved facets from the un-tapered regions and the tapered regions were imaged. The images show shallow voids of different shapes confined to the fiber core. After longitudinally polishing a segment of the PCF, we imaged the PCF internal structure's top view, revealing the fuse voids' geometries and periodicity. In addition, fiber fuse was terminated in one PCF sample by a fast laser shutdown, hence saving a small segment from catastrophic damage. Four-wave-mixing was performed on this transmissive segment to estimate the dispersion. The results yielded an evident hole-pitch ratio change after fiber fuse. To our knowledge, this is the first report of fiber fuse on non-silica glass fibers and the first study of its aftermath on this un-destroyed segment of PCFs. PMID- 29601001 TI - Time-of-flight detection of femtosecond laser pulses for precise measurement of large microelectronic step height. AB - We propose and demonstrate a new method which employs time-of-flight detection of femtosecond laser pulses for precise height measurement of large steps. By using time-of-flight detection with fiber-loop optical-microwave phase detectors, precise measurement of large step height is realized. The proposed method shows uncertainties of 15 nm and 6.5 nm at sampling periods of 40 ms and 800 ms, respectively. This method employs only one free-running femtosecond mode-locked laser and requires no scanning of laser repetition rate, making it easier to operate. Precise measurements of 6 MUm and 0.5 mm step heights have been demonstrated, which show good functionality of this method for measurement of step heights. PMID- 29601002 TI - Influence of the shielding effect on the formation of a micro-texture on the cermet with nanosecond pulsed laser ablation. AB - The degree of laser pulse overlapping in a laser scanning path has a significant impact on the ablation regime in the laser machining of a micro-texture. In this Letter, a nanosecond pulsed laser is used to prepare the micro-scaled groove on WC-8Co cermet under different scanning speeds. It is observed that as the scanning speed increases, the ablated trace morphology in the first scanning pass transits from a succession of intermittent deep dimples to the consecutive overlapped shallow pits. The test result also indicates that ablated trace morphology with respect to the low scanning speed stems from a plume shielding effect. Moreover, the ablation regime considering the shielding effect in micro groove formation process is clarified. The critical scanning speed that can circumvent the shielding effect is also summarized with respect to different laser powers. PMID- 29601003 TI - Mechanism of large optical nonlinearity in gold nanoparticle films. AB - The Z-scan technique, using femtosecond (fs) laser pulses at 1480 nm laser pulses, was used to measure the nonlinear optical properties of gold (Au) nanoparticle (NP) films made by both nanosecond (ns) and fs pulsed laser deposition (PLD) in vacuum. At irradiance levels of 1*1012 Wm-2, the ns-PLD films displayed induced absorption with beta=4*10-5 mW-1, and a negative lensing effect with n2=-4.7*10-11 m2 W-1 with somewhat smaller values for the fs-PLD films. These values of n2 imply an unphysically large change in the real part of the refractive index, demonstrating the need to take account of nonlinear changes of the Fresnel coefficients and multiple beam interference in Z-scan measurements on nanoscale films. Following this approach, the Z-scan observations were analyzed to determine the effective complex refractive index of the NP film at high irradiance. It appears that at high irradiance the NP film behaves as a metal, while at low irradiance it behaves as a low-loss dielectric. Thus, it is conjectured that, for high irradiance near the waist of the Z-scan laser beam, laser driven electron tunneling between NPs gives rise to metal-like optical behavior. PMID- 29601004 TI - Curving h-BN thin films can create extra phonon polariton modes. AB - Hexagonal boron nitride (h-BN) thin films support volume-confined phonon polariton modes within the bulk material as well as surface-confined modes at the edges of thin films. In this Letter, we theoretically investigate the phonon polaritons in curved h-BN thin films. One-dimensional guided phonon polariton modes are found, which are caused by the curved geometry and do not exist in extended flat films. These modes are guided along a specific direction with relatively low propagation losses. So far, one-dimensional guided phonon polariton modes have only been proposed in nanowire and nanoribbon structures. Our study offers another way with the advantage of keeping the h-BN film intact, which can avoid huge scattering losses due to the structural defects. These investigations may offer an easy and robust approach toward phonon-polariton based nanophotonic circuitry. PMID- 29601005 TI - Resource-theoretic approach to vectorial coherence. AB - We propose a formal resource-theoretic approach to assess the coherence between partially polarized electromagnetic fields. From this framework, we identify two resource theories for the vectorial coherence: polarization-sensitive coherence and polarization-insensitive coherence. For each theory, we find the set of incoherent states and a class of operations that preserve this set (i.e., the incoherent operations). Both resource theories are endowed with a certain preorder relation that provides a hierarchy among the coherence-polarization states; thus, a necessary condition to consider in deciding whether a quantity is proper to measure the vectorial coherence is that it respects such a hierarchy. Finally, we examine most previously introduced coherence measures from this perspective. PMID- 29601006 TI - Spectral interpretation of Talbot self-healing effect and application to optical arbitrary waveform generation. AB - The Talbot effect has the intrinsic capability of mitigating the effects of grating imperfections. Here we investigate, in the frequency domain, the influence of an imperfect grating on the Talbot images. In particular, we show that for specific propagation distances, the spectra of the individual Talbot images are directly related to the envelope of the grating transmission function, mapped in the spectral domain. This novel space-to-frequency mapping property enables us to describe the capability of image restoration (or self-healing) of the Talbot effect, in terms of spectral filtering. The transposition of this effect from the spatial to the temporal domain offers promising possibilities for the spectral shaping of optical waveforms. PMID- 29601007 TI - Watt-level dysprosium fiber laser at 3.15 MUm with 73% slope efficiency. AB - Rare-earth-doped fiber lasers are emerging as promising high-power mid-infrared sources for the 2.6-3.0 MUm and 3.3-3.8 MUm regions based on erbium and holmium ions. The intermediate wavelength range, however, remains vastly underserved, despite prospects for important manufacturing and defense applications. Here, we demonstrate the potential of dysprosium-doped fiber to solve this problem, with a simple in-band pumped grating-stabilized linear cavity generating up to 1.06 W at 3.15 MUm. A slope efficiency of 73% with respect to launched power (77% relative to absorbed power) is achieved-the highest value for any mid-infrared fiber laser to date, to the best of our knowledge. Opportunities for further power and efficiency scaling are also discussed. PMID- 29601008 TI - Laser stabilization with a frequency-to-voltage chip for narrow-line laser cooling. AB - We use integrated circuit-based frequency-to-voltage conversion of a frequency comb beat signal as the means for laser frequency stabilization that is suitable for narrow-line laser cooling. The method is compared to an atomic beam lock where the laser frequency instability for the new scheme shows an improvement of 2 orders of magnitude at sub-1 s and grants a lock-capture range that is approximately 30 times greater. We employ the locking method on a 1111.6 nm laser that is frequency doubled and used in a dual-wavelength magneto-optical trap for Yb171 atoms, producing atomic cloud temperatures of ~20 MUK. PMID- 29601009 TI - Polarization-insensitive four-channel coarse wavelength-division (de)multiplexer based on Mach-Zehnder interferometers with bent directional couplers and polarization rotators. AB - A polarization-insensitive four-channel coarse wavelength-division multiplexing (CWDM) (de)multiplexer based on Mach-Zehnder interferometers is proposed and demonstrated. By utilizing the bent directional couplers and the polarization rotators, the CWDM (de)multiplexer could work for both transverse electric and transverse magnetic polarizations. The measurement results of the fabricated devices show that the 1-dB bandwidth is ~15 nm for dual polarizations, and the polarization dependent losses are <~0.5 dB for all four channels.

AB - Whispering-gallery mode (WGM) resonators combine small optical mode volumes with narrow resonance linewidths, making them exciting platforms for a variety of applications. Here we report a flying WGM microlaser, realized by optically trapping a dye-doped microparticle within a liquid-filled hollow-core photonic crystal fiber (HC-PCF) using a CW laser and then pumping it with a pulsed excitation laser whose wavelength matches the absorption band of the dye. The laser emits into core-guided modes that can be detected at the endfaces of the HC PCF. Using radiation forces, the microlaser can be freely propelled along the HC PCF over multi-centimeter distances-orders of magnitude farther than in previous experiments where tweezers and fiber traps were used. The system can be used to measure temperature with high spatial resolution, by exploiting the temperature dependent frequency shift of the lasing modes, and may also permit precise delivery of light to remote locations. PMID- 29601011 TI - Local activation of surface and hybrid acoustic waves in optical microwires. AB - Elastic vibrations in subwavelength structures have gained importance recently in fundamental light-matter studies and various optoacoustic applications. Existing techniques have revealed the presence of distinct acoustic resonances inside silica microwires yet remain unable to individually localize them. Here, we locally activate distinct classes of acoustic resonances inside a tapered fiber using a phase-correlation distributed Brillouin method. Experimental results verify the presence of surface and hybrid acoustic waves at distinct fiber locations and demonstrate, to the best of our knowledge, the first distributed surface acoustic wave measurement. This technique is important for understanding properties of optoacoustic interactions and enabling designs of novel optomechanical devices.

AB - In this Letter, to the best of our knowledge, a novel wideband microwave burst detection system is realized by utilizing photonics-assisted wavelength and time division multiplexing, in conjunction with optical storage. Deploying a coherent electro-optical dual comb and a recirculating optical frequency shifter with ~1.28 MUs round-rip delay, the proof-of-concept experimental system demonstrates the interrogation of ~1 MUs radio frequency (RF) bursts with up to an 8 GHz bandwidth and arbitrary hopping pattern at 1 MHz resolution and a refresh rate of ~60 kHz using an 80 MHz RF detection unit. The proposed system can be easily upgraded to higher bandwidths and longer burst time apertures with suitable hardware.

AB - We experimentally demonstrate single-lane 112 Gb/s four-level pulse-amplitude modulation signal transmission over 80 km standard single-mode fiber (SSMF) by digital chromatic dispersion (CD) pre-management. By theoretically investigating the interplay between CD and self-phase modulation (SPM) during the SSMF transmission, we identify that the SPM induced impairment can be optically mitigated by the residual positive CD of the SSMF link. Thanks to the digital CD pre-management for the purpose of both CD compensation and nonlinear impairment mitigation, a simplified Volterra filter equalizer is good enough to achieve bit error rate below the 7% hard-decision forward error correcting threshold. PMID- 29601014 TI - Sidelobe apodization in optical pulse compression reflectometry for fiber optic distributed acoustic sensing. AB - We demonstrate a technique to reduce the sidelobes in optical pulse compression reflectometry for distributed acoustic sensing. The technique is based on using a Gaussian probe pulse with linear frequency modulation. This is shown to improve the sidelobe suppression by 13 dB compared to the use of square pulses without any significant penalty in terms of spatial resolution. In addition, a 2.25 dB enhancement in signal-to-noise ratio is calculated compared to the use of receiver-side windowing. The method is tested by measuring 700 Hz vibrations with a 140 nepsilon amplitude at the end of a 50 km fiber sensing link with 34 cm spatial resolution, giving a record 147,058 spatially resolved points.

AB - In this Letter, the transient nonlinear absorption of three-dimensional (3D) topological Dirac semimetal Cd3As2 thin film was characterized in the near infrared band. By performing broadband pump-probe measurements, we experimentally proved that molecular beam epitaxy (MBE) grown Cd3As2 exhibits strong and tunable saturable absorption effects across 1-2 MUm. By further inserting the Cd3As2 film into the cavities of Tm- and Er-doped fiber lasers, we obtained stable mode locked operations at 1.96 and 1.56 MUm. Our results experimentally establish that Cd3As2 is a promising broadband saturable absorber (SA) for pulsed lasers in the infrared range. PMID- 29601016 TI - Critically phase-matched Ti:sapphire-laser-pumped deep-infrared femtosecond optical parametric oscillator based on CdSiP2. AB - We report a high-repetition-rate femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) based on type-I critical phase-matching in CdSiP2 (CSP), pumped directly by a Ti:sapphire laser. Using angle-tuning in the CSP crystal, the OPO can be continuously tuned across 7306-8329 nm (1201-1369 cm-1) in the deep-IR. It delivers up to 18 mW of idler average power at 7306 nm and >7 mW beyond 8000 nm at 80.5 MHz repetition rate, with the spectra exhibiting bandwidths of >150 nm across the tuning range. Moreover, the signal is tunable across 1128-1150 nm in the near-infrared, providing up to 35 mW of average power in ~266 fs pulses at 1150 nm. Both beams exhibit single-peak Gaussian distribution in TEM00 spatial profile. With an equivalent spectral brightness of ~5.6*1020photons s-1 mm-2 sr-10.1% BW-1, this OPO represents a viable alternative to synchrotron and supercontinuum sources for deep-IR applications in spectroscopy, metrology, and medical diagnostics. PMID- 29601017 TI - Grayness-dependent emission of dispersive waves from dark solitons in optical fibers. AB - We report the experimental observation of dispersive wave emission from gray solitons propagating in the normal dispersion region of an optical fiber. Besides observing for the first time, to the best of our knowledge, the emission of a dispersive wave from an isolated dark soliton, we show that the dispersive wave frequency and amplitude strongly depend on soliton grayness. This process can be explained by the higher-order dispersion contribution into the phase-matching condition and the grayness of the soliton. Numerical simulations and theoretical predictions are in good agreement with the experiments.

AB - Bragg reflectors (BRFs) are essential elements in optical telecommunication and sensing applications. Their miniaturization down to the sub-micron scale has been achieved in silicon-on-insulator chips. However, their tunability is limited only to thermal tuning. In order to achieve a faster and more practical tunability operation, here we report on electro-optically tunable BRFs with ~14 dB signal filtering on a lithium-niobate-on-insulator platform, while keeping sub-micron cross-sections. Due to the lithium niobate electro-optic properties and the chosen electrodes configuration, a Bragg tunability coefficient of 23.37+/-0.55 pm/V is achieved, which enhances ~33 times the tunability performance of state-of the-art BRFs.

PMID- 29601020 TI - Approach for temperature-insensitive strain measurement using a dual-core As2Se3 PMMA taper. AB - A temperature-insensitive strain sensor is proposed and demonstrated based on a dual-core As2Se3-polymethyl methacrylate (PMMA) taper. Longitudinal and transverse forces on the As2Se3 cores are induced by thermal expansion/contraction of the PMMA cladding due to an order of magnitude difference between the thermal expansion coefficients of As2Se3 and PMMA. At an optimal PMMA layer thickness, the wavelength shift caused by the thermally induced forces on the refractive index of the dual-core fiber cores counterbalances that caused by the thermally induced fiber length variation leading to temperature-insensitive transmission. Temperature-insensitive strain measurement over a temperature range from 30 degrees C to 40 degrees C is demonstrated in a dual-core As2Se3-PMMA fiber with an As2Se3 core diameter of 0.61 MUm and a PMMA cladding diameter of 34.4 MUm. Thermally induced forces in hybrid fibers open the path towards the realization of novel sensors and devices that are immune to temperature fluctuations.

PMID- 29601023 TI - Spin-optomechanical coupling between light and a nanofiber torsional mode. AB - Light that carries linear or angular momentum can interact with a mechanical object, giving rise to optomechanical effects. In particular, a photon can transfer its intrinsic angular momentum to an object when the object either absorbs the photon or changes the photon polarization, as in an action/reaction force pair. Here, we demonstrate resonant driving of torsional mechanical modes of a single-mode tapered optical nanofiber using spin angular momentum. The nanofiber torsional mode spectrum is characterized by polarimetry, showing narrow natural resonances (Q~2,000). By sending amplitude-modulated light through the nanofiber, we resonantly drive individual torsional modes as a function of the light polarization. By varying the input polarization to the fiber, we find the largest amplification of a mechanical oscillation (>35 dB) is observed when driving the system with light containing longitudinal spin on the nanofiber waist. These results present optical nanofibers as a platform suitable for quantum spin-optomechanics experiments. PMID- 29601024 TI - Broadband and high-efficiency vortex beam generator based on a hybrid helix array. AB - The vortex beam which carries the orbital angular momentum has versatile applications, such as high-resolution imaging, optical communications, and particle manipulation. Generating vortex beams with the Pancharatnam-Berry (PB) phase has drawn considerable attention for its unique spin-to-orbital conversion features. Despite the PB phase being frequency independent, an optical element with broadband high-efficiency circular polarization conversion feature is still needed for the broadband high-efficiency vortex beam generation. In this work, a broadband and high-efficiency vortex beam generator based on the PB phase is built with a hybrid helix array. Such devices can generate vortex beams with arbitrary topological charge. Moreover, vortex beams with opposite topological charge can be generated with an opposite handedness incident beam that propagates backward. The measured efficiency of our device is above 65% for a wide frequency range, with the relative bandwidth of 46.5%. PMID- 29601025 TI - Micro-hole drilling by tightly focused vector beams. AB - We demonstrated that azimuthally polarized beams offer high-speed laser micro hole drilling compared with radially and linearly polarized beams under a tight focusing condition. The speed was evaluated by piercing time by vector beams for several objective lenses with different numerical apertures (NAs). As a result, in the case of NA=0.63, the piercing time of an azimuthally polarized beam was 2.4 to 3.2 times shorter than that of a linearly polarized beam for all materials tested. Surprisingly, for NA=0.85, the difference is expanded to about 7.7 times for copper. This indicates that the number of reflections on the side wall of the hole played a significant role to give rise to the difference in the piercing time, depending on the polarization of the light beam.

AB - We propose a spectrally efficient digitized radio-over-fiber (D-RoF) system by grouping highly correlated neighboring samples of the analog signals into multidimensional vectors, where the k-means clustering algorithm is adopted for adaptive quantization. A 30 Gbit/s D-RoF system is experimentally demonstrated to validate the proposed scheme, reporting a carrier aggregation of up to 40 100 MHz orthogonal frequency division multiplexing (OFDM) channels with quadrate amplitude modulation (QAM) order of 4 and an aggregation of 10 100 MHz OFDM channels with a QAM order of 16384. The equivalent common public radio interface rates from 37 to 150 Gbit/s are supported. Besides, the error vector magnitude (EVM) of 8% is achieved with the number of quantization bits of 4, and the EVM can be further reduced to 1% by increasing the number of quantization bits to 7. Compared with conventional pulse coding modulation-based D-RoF systems, the proposed D-RoF system improves the signal-to-noise-ratio up to ~9 dB and greatly reduces the EVM, given the same number of quantization bits.

AB - We experimentally demonstrate a 12-mode group (21 spatial mode) cladding-pumped few-mode erbium-doped fiber amplifier. The differential modal gain (DMG) is dramatically reduced by using the double cladding erbium-doped fiber (DC-EDF) with a refractive index trench structure, which helps to tightly confine all 21 spatial modes in the core and to mitigate the bending loss. Our experimental results show that the DMG gain is about 3 dB when the average signal modal gain for all 12 mode groups is up to 15 dB across the C-band. Our method of using a DC EDF with a properly designed trench structure can be used to develop gain equalized few-mode amplifiers supporting more spatial modes. PMID- 29601028 TI - Integrated flexible-grid WDM transmitter using an optical frequency comb in microring modulators. AB - Advanced optical interconnects require high-speed links, which can be achieved by combining high channel rates with wavelength-division multiplexing (WDM). We report a multi-channel transmitter using cascaded microring modulators (MRMs) in silicon photonics. One MRM works as a flexible-grid optical comb generator, while the others work as channel modulators. With a single-wavelength laser input, we achieve flexible channel spacing (up to 25 GHz) with a tone-to-noise ratio above 54 dB at low power consumption of less than 4.6 mW. We examine experimentally multi-channel transmission modulating data onto adjacent comb lines without significant signal crosstalk. This single-laser, flexible-grid WDM transmitter is a scalable solution: more comb lines can be obtained using uncoupled MRMs in a series. To the best of our knowledge, this is the first demonstration of monolithic integration of a comb generator and multi-channel modulators for ultra compact, power-efficient WDM photonic interconnects.

AB - We report on spectral range stabilization in a self-sweeping laser by adding a narrowband fiber Bragg grating (FBG) to the output mirror in the Michelson configuration. The effects of FBG reflectivity and optical path difference in the Michelson interferometer on the laser spectral dynamics are investigated. Optimization of the interferometer allows us to demonstrate broadband (over 16 nm) self-sweeping operation and reduction of the start and stop wavelength fluctuations by two orders and one order of magnitude (~100 and 15 times) for start and stop bounds, respectively (down to several picometers). The proposed approaches significantly improve quality of the spectral dynamics and facilitate application of the self-sweeping lasers. PMID- 29601030 TI - High-efficiency 1064 nm nonplanar ring oscillator Nd:YAG laser with diode pumping at 885 nm. AB - We experimentally demonstrate a monolithic single-frequency nonplanar ring oscillator (NPRO) laser pumped by diode lasers from a thermally excited ground level directly into a metastable level of Nd3+:YAG gain medium. Continuous-wave output power of 4.54 W is obtained at 1064 nm with 7.6 W input at 885 nm, and the slope efficiency is 76.9% at incident power above 2 W. Compared with the 50.7% slope efficiency obtained using 808 nm pumping for the same NPRO, this direct pumping shows a potential advantage in improving the energy efficiency. The observation is consistent with an analysis of the heat generation in both direct and traditional pumping schemes. The power fluctuation is measured to be within 0.8% at 3 W output during a 10 h period. PMID- 29601031 TI - All-fiber gas sensor with intracavity photothermal spectroscopy. AB - We present an all-fiber intracavity photothermal (IC-PT) spectroscopic gas sensor with a hollow-core photonic bandgap fiber (HC-PBF) gas cell. The gas cell is placed inside a fiber-ring laser cavity to achieve higher laser light intensity in the hollow core and hence higher PT modulation signal. An experiment with a 0.62-m-long HC-PBF gas cell demonstrated a noise equivalent concentration of 176 ppb acetylene. Theoretical modeling shows that the IC-PT sensor has the potential of achieving sub-ppb (parts-per-billion) acetylene detection sensitivity. PMID- 29601032 TI - Spectral shifts of stimulated Rayleigh-Mie scattering in Ag nanoparticle colloids. AB - Stimulated Rayleigh-Mie scattering (SRMS) in two-photon absorption liquids is realized by a Fourier-transform-limited pulsed Nd-glass laser. For the first time, to the best of our knowledge, we have measured anti-Stokes spectral shifts of SRMS in toluene and hexane colloids of Ag nanoparticles, as well as in pure toluene. These values appreciably exceed the Rayleigh line width in those liquids. The four-wave mixing method is applied both experimentally and theoretically to display the process as Rayleigh-induced parametric generation. We show that the amplification effect is provided predominantly by thermally induced coherent polarization oscillations, while an interference-assisted thermal grating provides formation of a self-induced optical cavity inside the interaction region. PMID- 29601033 TI - High-power, fixed, and tunable wavelength, grating-free cascaded Raman fiber lasers. AB - Cascaded Raman lasers enable high powers at various wavelength bands inaccessible with conventional rare-earth-doped lasers. The input and output wavelengths of conventional implementations are fixed by the constituent fiber gratings necessary for cascaded Raman conversion. We demonstrate here a simple architecture for high-power, fixed, and wavelength tunable, grating-free, cascaded Raman conversion between different wavelength bands. The architecture is based on the recently proposed distributed feedback Raman lasers. Here, we implement a module which converts the ytterbium band to the eye-safe 1.5 MUm region. We demonstrate pump-limited output powers of over 30 W in fixed and continuously wavelength tunable configurations. PMID- 29601034 TI - AlGaAs-based vertical-external-cavity surface-emitting laser exceeding 4 W of direct emission power in the 740-790 nm spectral range. AB - An optically pumped vertical-external-cavity surface-emitting laser (VECSEL) for direct emission in the 740-790 nm wavelength region is reported. The gain structure is based on 12 AlGaAs quantum wells. We demonstrate wavelength tuning between 747 nm and 788 nm and free-running operation with a maximum power of 4.24 W (pump power limited) for a heat sink temperature of 14 degrees C. This laser system addresses a spectral gap not currently covered by VECSEL technology and represents the most powerful VECSEL reported within the 7XX-nm wavelength region. PMID- 29601035 TI - Simultaneous viscosity and elasticity measurement using laser speckle contrast imaging. AB - Viscosity and elasticity are closely related to the physiological characteristics of biological tissues. This Letter reports a simultaneous quantitative measurement of these parameters realized with the laser speckle contrast imaging method. The propagation of a Rayleigh wave induced by an acoustic speaker is traced, and the frequency-dependent velocity dispersion is extracted with the frequency-wavenumber spectrum analysis method. The viscosity and elasticity moduli of oil-in-gelatin tissue-mimicking phantoms are calculated by fitting the dispersion curves to the Voigt model. The method is validated by comparing it with the results obtained by using a conventional mechanical rheometer. PMID- 29601036 TI - Design and demonstration of ultra-high-Q silicon microring resonator based on a multi-mode ridge waveguide. AB - We present the design and experimental demonstration of the ultra-high-Q-factor silicon microring resonator based on a multi-mode ridge waveguide. The multi-mode ridge waveguide is designed to decrease the propagation loss and to improve the Q factor. The ultra-high Q factor of 1.1*106 is experimentally demonstrated, with the free spectrum range of 0.208 nm. The single-mode ridge waveguide is used in the coupling region to reduce the dimension of the microring resonator, and the bend radius is only 20 MUm. To precisely control the resonance wavelength, a small heater is implemented on the silicon microring resonator with the tuning efficiency of 7.1 pm/mW. The degenerate four-wave mixing of the silicon microring resonator is investigated, and the conversion efficiency is measured to be -15.5 dB without optimizing the dispersion of the microring resonator and carriers extraction. PMID- 29601037 TI - All-fiber radially/azimuthally polarized lasers based on mode coupling of tapered fibers. AB - We demonstrate a mode converter with an insertion loss of 0.36 dB based on mode coupling of tapered single-mode and two-mode fibers, and realize all-fiber flexible cylindrical vector lasers at 1550 nm. Attributing to the continuous distribution of a tangential electric field at taper boundaries, the laser is switchable between the radially and azimuthally polarized states by adjusting the input polarization. In the temporal domain, the operation is controllable among continuous-wave, Q-switched, and mode-locked statuses by changing the saturable absorber or pump strength. The duration of Q-switched radially/azimuthally polarized laser spans from 10.4/10.8 to 6/6.4 MUs at the pump range of 38 to 58 mW, while that of the mode-locked pulse varies from 39.2/31.9 to 5.6/5.2 ps by controlling the laser bandwidth. The proposed laser combines the features of a cylindrical vector beam, a fiber laser, and an ultrafast pulse, providing a special and cost-effective source for practical applications. PMID- 29601038 TI - Terahertz adaptive optics with a deformable mirror. AB - We report on the wavefront correction of a terahertz (THz) beam using adaptive optics, which requires both a wavefront sensor that is able to sense the optical aberrations, as well as a wavefront corrector. The wavefront sensor relies on a direct 2D electro-optic imaging system composed of a ZnTe crystal and a CMOS camera. By measuring the phase variation of the THz electric field in the crystal, we were able to minimize the geometrical aberrations of the beam, thanks to the action of a deformable mirror. This phase control will open the route to THz adaptive optics in order to optimize the THz beam quality for both practical and fundamental applications. PMID- 29601039 TI - Optimized inhibited-coupling Kagome fibers at Yb-Nd:Yag (8.5 dB/km) and Ti:Sa (30 dB/km) ranges. AB - We report on the development of hypocycloid core-contour inhibited-coupling (IC) Kagome hollow-core photonic crystal fibers (HC-PCFs) with record transmission loss and spectral coverage that include the common industrial laser wavelengths. Using the scaling of the confinement loss with the core-contour negative curvature and the silica strut thickness, we fabricated an IC Kagome HC-PCF for Yb and Nd:Yag laser guidance with record loss level of 8.5 dB/km associated with a 225-nm-wide 3-dB bandwidth. A second HC-PCF is fabricated with reduced silica strut thickness while keeping the hypocycloid core contour. It exhibits a fundamental transmission window spanning down to the Ti:Sa spectral range and a loss figure of 30 dB/km at 750 nm. The fibers' modal properties and bending sensitivity show these HC-PCFs to be ideal for ultralow-loss, flexible, and robust laser beam delivery. PMID- 29601040 TI - Two-dimensional arbitrary nano-manipulation on a plasmonic metasurface. AB - In this Letter, we report on a plasmonic nano-ellipse metasurface with the purpose of trapping and two-dimensional (2D) arbitrary transport of nanoparticles by means of rotating the polarization of an excitation beam. The locations of hot spots within a metasurface are polarization dependent, thus making it possible to turn on/off the adjacent hot spots and then convey the trapped target by rotating the incident polarization state. For the case of a metasurface with a unit cell of perpendicularly orientated nano-ellipses, the hot spots with higher intensities are located at both apexes of the nano-ellipse whose major axis is parallel to the direction of polarization. When the polarization gradually rotates to its counterpart direction, the trapped particle may move around the ellipse and transfer to the most adjacent ellipse, due to the unbalanced trap potentials around the nano-ellipse. Clockwise and counterclockwise rotation would guide the particle in a different direction, which makes it possible to convey the particle arbitrarily within the plasmonic metasurface by setting a time sequence of polarization rotation. As confirmed by the three-dimensional finite difference time-domain analysis, our design offers a novel scheme of 2D arbitrary transport with nanometer accuracy, which could be used in many on-chip optofluidic applications. PMID- 29601041 TI - Line-scan spectrum-encoded imaging by dual-comb interferometry. AB - Herein, the method of spectrum-encoded dual-comb interferometry is introduced to measure a three-dimensional (3-D) profile with absolute distance information. By combining spectral encoding for wavelength-to-space mapping, dual-comb interferometry for decoding and optical reference for calibration, this system can obtain a 3-D profile of an object at a stand-off distance of 114 mm with a depth precision of 12 MUm. With the help of the reference arm, the absolute distance, reflectivity distribution, and depth information are simultaneously measured at a 5 kHz line-scan rate with free-running carrier-envelope offset frequencies. To verify the concept, experiments are conducted with multiple objects, including a resolution test chart, a three-stair structure, and a designed "ECNU" letter chain. The results show a horizontal resolution of ~22 MUm and a measurement range of 1.93 mm. PMID- 29601042 TI - MeV electron acceleration at 1 kHz with <10 mJ laser pulses: erratum.

PMID- 29601043 TI - All-fiber all-normal-dispersion femtosecond laser with a nonlinear multimodal interference-based saturable absorber. AB - In this Letter, we demonstrate, to the best of our knowledge, the first all-fiber all-normal-dispersion ytterbium-doped oscillator with a nonlinear multimodal interference-based saturable absorber capable of generating ultrashort dissipative soliton pulses. Additional to functioning as a saturable absorber, the use of multimode fiber segments between single-mode fibers also ensures the bandpass filtering via multimode interference reimaging necessary to obtain dissipative soliton mode locking. The oscillator generates dissipative soliton pulses at 1030 nm with 5.8 mW average power, 5 ps duration, and 44.25 MHz repetition rate. Pulses are dechirped to 276 fs via an external grating compressor. All-fiber cavity design ensures high stability, and ~70 dB sideband suppression is measured in the radio frequency spectrum. Numerical simulations are performed to investigate cavity dynamics, and obtained results are well matched with experimental observations. The proposed cavity presents an alternative approach to achieve all-fiber dissipative soliton mode locking with a simple and low-cost design. PMID- 29601044 TI - Ultracompact high-resolution photoacoustic microscopy. AB - Optical resolution photoacoustic microscopy (ORPAM), benefiting from rich optical contrast, scalable acoustic resolution, and deep penetration depth, is of great importance for the fields of biology and medicine. However, limited by the size and performance of reported optical/acoustic scanners, existing portable/handheld ORPAMs are bulky and heavy, and suffer from low imaging quality/speed. Here, we present an ultracompact ORPAM probe, which is miniature and light, and has high imaging quality. The probe only weighs 20 grams and has an outer size of 22 mm*30 mm*13 mm, a high lateral resolution of 3.8 MUm, and an effective imaging domain of 2 mm*2 mm. To show its advantages over existing ORPAMs, we apply this probe to image vasculatures of internal organs in a rat abdominal cavity and inspect the entire human oral cavity. PMID- 29601045 TI - Formulating the design of two freeform lens surfaces for point-like light sources. AB - Two freeform surfaces provide more degrees of freedom in designing illumination optics and can yield a better solution. The existing methods for point-like sources are mostly valid in designing one freeform surface. Designing two freeform surfaces for point-like sources still remains a challenging issue. In this Letter, we develop a general formulation of designing two freeform lens surfaces for point-like sources. The proposed method is very robust in designing freeform lenses with two elaborately designed surfaces. The examples clearly show that using two freeform surfaces yields better solutions to challenging illumination problems with ultra-high energy efficiency. PMID- 29601046 TI - Observation of subfemtosecond fluctuations of the pulse separation in a soliton molecule. AB - In this work, we study the timing instability of a scalar twin-pulse soliton molecule generated by a passively mode-locked Er-fiber laser. Subfemtosecond precision relative timing jitter characterization between the two solitons composing the molecule is enabled by the balanced optical cross-correlation (BOC) method. Jitter spectral density reveals a short-term (on the microsecond to millisecond timescale) random fluctuation of the pulse separation even in the robust stationary soliton molecules. The root-mean-square (rms) timing jitter is on the order of femtoseconds depending on the pulse separation and the mode locking regime. The lowest rms timing jitter is 0.83 fs, which is observed in the dispersion managed mode-locking regime. Moreover, the BOC method has proved to be capable of resolving the soliton interaction dynamics in various vibrating soliton molecules. PMID- 29601047 TI - Estimating Dynamic Signals From Trial Data With Censored Values. AB - Censored data occur commonly in trial-structured behavioral experiments and many other forms of longitudinal data. They can lead to severe bias and reduction of statistical power in subsequent analyses. Principled approaches for dealing with censored data, such as data imputation and methods based on the complete data's likelihood, work well for estimating fixed features of statistical models but have not been extended to dynamic measures, such as serial estimates of an underlying latent variable over time. Here we propose an approach to the censored data problem for dynamic behavioral signals. We developed a state-space modeling framework with a censored observation process at the trial timescale. We then developed a filter algorithm to compute the posterior distribution of the state process using the available data. We showed that special cases of this framework can incorporate the three most common approaches to censored observations: ignoring trials with censored data, imputing the censored data values, or using the full information available in the data likelihood. Finally, we derived a computationally efficient approximate Gaussian filter that is similar in structure to a Kalman filter, but that efficiently accounts for censored data. We compared the performances of these methods in a simulation study and provide recommendations of approaches to use, based on the expected amount of censored data in an experiment. These new techniques can broadly be applied in many research domains in which censored data interfere with estimation, including survival analysis and other clinical trial applications. PMID- 29601048 TI - Consensus clustering approach to group brain connectivity matrices. AB - A novel approach rooted on the notion of consensus clustering, a strategy developed for community detection in complex networks, is proposed to cope with the heterogeneity that characterizes connectivity matrices in health and disease. The method can be summarized as follows: (a) define, for each node, a distance matrix for the set of subjects by comparing the connectivity pattern of that node in all pairs of subjects; (b) cluster the distance matrix for each node; (c) build the consensus network from the corresponding partitions; and (d) extract groups of subjects by finding the communities of the consensus network thus obtained. Different from the previous implementations of consensus clustering, we thus propose to use the consensus strategy to combine the information arising from the connectivity patterns of each node. The proposed approach may be seen either as an exploratory technique or as an unsupervised pretraining step to help the subsequent construction of a supervised classifier. Applications on a toy model and two real datasets show the effectiveness of the proposed methodology, which represents heterogeneity of a set of subjects in terms of a weighted network, the consensus matrix. PMID- 29601050 TI - Editorial. PMID- 29601049 TI - Cognitive genomics: Linking genes to behavior in the human brain. AB - Correlations of genetic variation in DNA with functional brain activity have already provided a starting point for delving into human cognitive mechanisms. However, these analyses do not provide the specific genes driving the associations, which are complicated by intergenic localization as well as tissue specific epigenetics and expression. The use of brain-derived expression datasets could build upon the foundation of these initial genetic insights and yield genes and molecular pathways for testing new hypotheses regarding the molecular bases of human brain development, cognition, and disease. Thus, coupling these human brain gene expression data with measurements of brain activity may provide genes with critical roles in brain function. However, these brain gene expression datasets have their own set of caveats, most notably a reliance on postmortem tissue. In this perspective, I summarize and examine the progress that has been made in this realm to date, and discuss the various frontiers remaining, such as the inclusion of cell-type-specific information, additional physiological measurements, and genomic data from patient cohorts.

AB - Information theory provides a formal framework within which information processing and its disorders can be described. However, information theory has rarely been applied to modeling aspects of the cognitive neuroscience of schizophrenia. The goal of this article is to highlight the benefits of an approach based on information theory, including its recent extensions, for understanding several disrupted neural goal functions as well as related cognitive and symptomatic phenomena in schizophrenia. We begin by demonstrating that foundational concepts from information theory-such as Shannon information, entropy, data compression, block coding, and strategies to increase the signal-to noise ratio-can be used to provide novel understandings of cognitive impairments in schizophrenia and metrics to evaluate their integrity. We then describe more recent developments in information theory, including the concepts of infomax, coherent infomax, and coding with synergy, to demonstrate how these can be used to develop computational models of schizophrenia-related failures in the tuning of sensory neurons, gain control, perceptual organization, thought organization, selective attention, context processing, predictive coding, and cognitive control. Throughout, we demonstrate how disordered mechanisms may explain both perceptual/cognitive changes and symptom emergence in schizophrenia. Finally, we demonstrate that there is consistency between some information-theoretic concepts and recent discoveries in neurobiology, especially involving the existence of distinct sites for the accumulation of driving input and contextual information prior to their interaction. This convergence can be used to guide future theory, experiment, and treatment development.

AB - Disruptive behaviour problems in preschool children are significant risk factors for, and potential components of, neurodevelopmental and mental health disorders. Some noncompliance, temper tantrums and aggression between 2 and 5 years of age are normal and transient. However, problematic levels of disruptive behaviour, specifically when accompanied by functional impairment and/or significant distress, should be identified because early intervention can improve outcome trajectories. This position statement provides an approach to early identification using clinical screening at periodic health examinations, followed by a systematic mental health examination that includes standardized measures. The practitioner should consider a range of environmental, developmental, family and parent-child relationship factors to evaluate the clinical significance of disruptive behaviours. Options within a management plan include regular monitoring, accompanied by health guidance and parenting advice, referral to parent behaviour training as a core evidence-based intervention, and referral to specialty care for preschool children with significant disruptive behaviours, developmental or mental health comorbidities, or who are not responding to first line interventions.

AB - Reinforcement learning and decision-making (RLDM) provide a quantitative framework and computational theories with which we can disentangle psychiatric conditions into the basic dimensions of neurocognitive functioning. RLDM offer a novel approach to assessing and potentially diagnosing psychiatric patients, and there is growing enthusiasm for both RLDM and computational psychiatry among clinical researchers. Such a framework can also provide insights into the brain substrates of particular RLDM processes, as exemplified by model-based analysis of data from functional magnetic resonance imaging (fMRI) or electroencephalography (EEG). However, researchers often find the approach too technical and have difficulty adopting it for their research. Thus, a critical need remains to develop a user-friendly tool for the wide dissemination of computational psychiatric methods. We introduce an R package called hBayesDM (hierarchical Bayesian modeling of Decision-Making tasks), which offers computational modeling of an array of RLDM tasks and social exchange games. The hBayesDM package offers state-of-the-art hierarchical Bayesian modeling, in which both individual and group parameters (i.e., posterior distributions) are estimated simultaneously in a mutually constraining fashion. At the same time, the package is extremely user-friendly: users can perform computational modeling, output visualization, and Bayesian model comparisons, each with a single line of coding. Users can also extract the trial-by-trial latent variables (e.g., prediction errors) required for model-based fMRI/EEG. With the hBayesDM package, we anticipate that anyone with minimal knowledge of programming can take advantage of cutting-edge computational-modeling approaches to investigate the underlying processes of and interactions between multiple decision-making (e.g., goal-directed, habitual, and Pavlovian) systems. In this way, we expect that the hBayesDM package will contribute to the dissemination of advanced modeling approaches and enable a wide range of researchers to easily perform computational psychiatric research within different populations.

PMID- 29601065 TI - DeepScope: Nonintrusive Whole Slide Saliency Annotation and Prediction from Pathologists at the Microscope. AB - Modern digital pathology departments have grown to produce whole-slide image data at petabyte scale, an unprecedented treasure chest for medical machine learning tasks. Unfortunately, most digital slides are not annotated at the image level, hindering large-scale application of supervised learning. Manual labeling is prohibitive, requiring pathologists with decades of training and outstanding clinical service responsibilities. This problem is further aggravated by the United States Food and Drug Administration's ruling that primary diagnosis must come from a glass slide rather than a digital image. We present the first end-to end framework to overcome this problem, gathering annotations in a nonintrusive manner during a pathologist's routine clinical work: (i) microscope-specific 3D printed commodity camera mounts are used to video record the glass-slide-based clinical diagnosis process; (ii) after routine scanning of the whole slide, the video frames are registered to the digital slide; (iii) motion and observation time are estimated to generate a spatial and temporal saliency map of the whole slide. Demonstrating the utility of these annotations, we train a convolutional neural network that detects diagnosis-relevant salient regions, then report accuracy of 85.15% in bladder and 91.40% in prostate, with 75.00% accuracy when training on prostate but predicting in bladder, despite different pathologists examining the different tissues. When training on one patient but testing on another, AUROC in bladder is 0.79+/-0.11 and in prostate is 0.96+/-0.04. Our tool is available at https://bitbucket.org/aschaumberg/deepscope. PMID- 29601066 TI - Nonrandom network connectivity comes in pairs. AB - Overrepresentation of bidirectional connections in local cortical networks has been repeatedly reported and is a focus of the ongoing discussion of nonrandom connectivity. Here we show in a brief mathematical analysis that in a network in which connection probabilities are symmetric in pairs, Pij = Pji , the occurrences of bidirectional connections and nonrandom structures are inherently linked; an overabundance of reciprocally connected pairs emerges necessarily when some pairs of neurons are more likely to be connected than others. Our numerical results imply that such overrepresentation can also be sustained when connection probabilities are only approximately symmetric.

AB - Drugs fulfilling the criterion of a standard drug will always become panacea provided, if they are used properly. On the other hand, a poorly manufactured drug however used skillfully, will prove to be a poison. Texts of Ayurveda, do mention hazards of drugs, which are not properly manufactured or administered. Art of drug administration is unique in this ancient medical science that cautions towards concentrating on dose, indications, contra-indications, suitable vehicle, specific diet, certain restrictions etc., while administering medicines in suitable individuals. Though a huge amount of information is available and evidences are being generated on the usefulness of traditional practices in global healthcare; there is a need of generating awareness on Promoting rational use of traditional medicines in particular to Ayurvedic drugs. Conventional researchers wish to work on traditional formulations have to understand traditional principles and involve traditional physicians in their researches in the benefit of mankind. PMID- 29601074 TI - Assessing Progression of Resident Proficiency during Ophthalmology Residency Training: Utility of Serial Clinical Skill Evaluations. AB - Objective: The Accreditation Council for Graduate Medical Education (ACGME) has mandated that residency programs document progression of competency-based outcomes. The Ophthalmic Clinical Evaluation Exercise (OCEX) assesses clinical skills in ophthalmology residents during patient encounters. Although OCEX has been validated for assessing several of the ACGME-mandated competencies, it was unclear whether OCEX can measure the development of proficiency during residency. This study evaluated whether OCEX can discriminate skill levels across years in training. Methods: In 2017, the authors performed a retrospective analysis on modified OCEX evaluations collected for 22 residents over 3 years at 2 residency programs. OCEX subcomponent scores were averaged to generate a mean score for each evaluation, followed by linear regression analysis for mean scores over time for individual residents. One-way ANOVA with repeated measures was used to compare scores aggregated over an academic year between resident classes. The authors also surveyed internal faculty evaluators and nationwide ophthalmology residency program directors on their use of OCEX. Results: Mean OCEX scores for individual residents and resident class averages showed variable trajectories over the course of residency. There was no consistent effect of increasing level of training on scores. Surveys of evaluators and program directors indicated different interpretations of the grading scale anchors and irregular participation by faculty. Conclusion: This dataset suggests that, despite clear behavioral anchors and faculty development on the use of the tool, evaluators still apply inconsistent grading standards that limit the OCEX from accurately monitoring longitudinal development of resident clinical performance in real world practice.

PMID- 29601076 TI - Syncope, Hypotension, and Falls in the Treatment of Hypertension: Results from the Randomized Clinical Systolic Blood Pressure Intervention Trial. AB - OBJECTIVE: To determine predictors of serious adverse events (SAEs) involving syncope, hypotension, and falls, with particular attention to age, in the Systolic Blood Pressure Intervention Trial. DESIGN: Randomized clinical trial. SETTING: Academic and private practices across the United States (N = 102). PARTICIPANTS: Adults aged 50 and older with a systolic blood pressure (SBP) of 130 to 180 mmHg at high risk of cardiovascular disease events, but without diabetes, history of stroke, symptomatic heart failure or ejection fraction less than 35%, dementia, or standing SBP less than 110 mmHg (N = 9,361). INTERVENTION: Treatment of SBP to a goal of less than 120 mmHg or 140 mmHg. MEASUREMENTS: Outcomes were SAEs involving syncope, hypotension, and falls. Predictors were treatment assignment, demographic characteristics, comorbidities, baseline measurements, and baseline use of cardiovascular medications. RESULTS: One hundred seventy-two (1.8%) participants had SAEs involving syncope, 155 (1.6%) hypotension, and 203 (2.2%) falls. Randomization to intensive SBP control was associated with greater risk of an SAE involving hypotension (hazard ratio (HR) = 1.67, 95% confidence interval (CI) = 1.21-2.32, P = .002), and possibly syncope (HR = 1.32, 95% CI = 0.98-1.79, P = .07), but not falls (HR = 0.98, 95% CI = 0.75 1.29, P = .90). Risk of all three outcomes was higher for participants with chronic kidney disease or frailty. Older age was also associated with greater risk of syncope, hypotension, and falls, but there was no age-by-treatment interaction for any of the SAE outcomes. CONCLUSIONS: Participants randomized to intensive SBP control had greater risk of hypotension and possibly syncope, but not falls. The greater risk of developing these events associated with intensive treatment did not vary according to age.

PMID- 29601077 TI - Investigation of factors influencing the immunogenicity of hCG as a potential cancer vaccine. AB - Human chorionic gonadotrophin (hCG) and its beta-subunit (hCGbeta) are tumour autocrine growth factors whose presence in the serum of cancer patients has been linked to poorer prognosis. Previous studies have shown that vaccines which target these molecules and/or the 37 amino acid C-terminal hCGbeta peptide (hCGbetaCTP) induce antibody responses in a majority of human recipients. Here we explored whether the immunogenicity of vaccines containing an hCGbeta mutant (hCGbetaR68E, designed to eliminate cross-reactivity with luteinizing hormone) or hCGbetaCTP could be enhanced by coupling the immunogen to different carriers [keyhole limpet haemocyanin (KLH) or heat shock protein 70 (Hsp70)] using different cross-linkers [1-ethyl-3(3-dimethylaminopropyl)carboiimide (EDC) or glutaraldehyde (GAD)] and formulated with different adjuvants (RIBI or Montanide ISA720). While there was little to choose between KLH and Hsp70 as carriers, their influence on the effectiveness of a vaccine containing the BAChCGbetaR68E mutant was less marked, presumably because, being a foreign species, this mutant protein itself might provide T helper epitopes. The mutant provided a significantly better vaccine than the hCGbetaCTP peptide irrespective of the carrier used, how it was cross-linked to the carrier or which adjuvant was used when hCG was the target. Nonetheless, for use in humans where hCG is a tolerated self-protein, the need for a carrier is of fundamental importance. Highest antibody titres were obtained by linking the BAChCGbetaR68E to Hsp70 as a carrier by GAD and using RIBI as the adjuvant, which also resulted in antibodies with significantly higher affinity than those elicited by hCGbetaCTP peptide vaccine. This makes this mutant vaccine a promising candidate for therapeutic studies in hCGbeta-positive cancer patients. PMID- 29601079 TI - Relationship between intraoperative non-technical performance and technical events in bariatric surgery. AB - BACKGROUND: The operating theatre is a unique environment with complex team interactions, where technical and non-technical performance affect patient outcomes. The correlation between technical and non-technical performance, however, remains underinvestigated. The purpose of this study was to explore these interactions in the operating theatre. METHODS: A prospective single-centre observational study was conducted at a tertiary academic medical centre. One surgeon and three fellows participated as main operators. All patients who underwent a laparoscopic Roux-en-Y gastric bypass and had the procedures captured using the Operating Room Black Box(r) platform were included. Technical assessment was performed using the Objective Structured Assessment of Technical Skills and Generic Error Rating Tool instruments. For non-technical assessment, the Non-Technical Skills for Surgeons (NOTSS) and Scrub Practitioners' List of Intraoperative Non-Technical Skills (SPLINTS) tools were used. Spearman rank order correlation and N-gram statistics were conducted. RESULTS: Fifty-six patients were included in the study and 90 procedural steps (gastrojejunostomy and jejunojejunostomy) were analysed. There was a moderate to strong correlation between technical adverse events (rs = 0.417-0.687), rectifications (rs = 0.380 0.768) and non-technical performance of the surgical and nursing teams (NOTSS and SPLINTS). N-gram statistics showed that after technical errors, events and prior rectifications, the staff surgeon and the scrub nurse exhibited the most positive non-technical behaviours, irrespective of operator (staff surgeon or fellow). CONCLUSION: This study demonstrated that technical and non-technical performances are related, on both an individual and a team level. Valuable data can be obtained around intraoperative errors, events and rectifications. PMID- 29601080 TI - Comparison of smartphone addiction and loneliness in high school and university students.

PMID- 29601081 TI - Outcome of open abdominal management following military trauma. AB - BACKGROUND: Temporary abdominal closure (TAC) is increasingly common after military and civilian major trauma. Primary fascial closure cannot be achieved after TAC in 30 per cent of civilian patients; subsequent abdominal wall reconstruction carries significant morbidity. This retrospective review aimed to determine this morbidity in a UK military cohort. METHODS: A prospectively maintained database of all injured personnel from the Iraq and Afghanistan conflicts was searched from 1 January 2003 to 31 December 2014 for all patients who had undergone laparotomy in a deployed military medical treatment facility. This database, the patients' hospital notes and their primary care records were searched. RESULTS: Laparotomy was performed in a total of 155 patients who survived to be repatriated to the UK; records were available for 150 of these patients. Seventy-seven patients (51.3 per cent) had fascial closure at first laparotomy, and 73 (48.7 per cent) had a period of TAC. Of the 73 who had TAC, two died before closure and two had significant abdominal wall loss from blast injury and were excluded from analysis. Of the 69 remaining patients, 65 (94 per cent) were able to undergo delayed primary fascial closure. The median duration of follow-up from injury was 1257 (range 1-4677) days for the whole cohort. Nine (12 per cent) of the 73 patients who underwent TAC subsequently developed an incisional hernia, compared with ten (13 per cent) of the 77 patients whose abdomen was closed at the primary laparotomy (P = 1.000). CONCLUSION: Rates of delayed primary closure of abdominal fascia after temporary abdominal closure appear high. Subsequent rates of incisional hernia formation were similar in patients undergoing delayed primary closure and those who had closure at the primary laparotomy. PMID- 29601082 TI - Cardiopulmonary fitness before and after neoadjuvant chemotherapy in patients with oesophagogastric cancer. AB - BACKGROUND: Neoadjuvant chemotherapy may have a detrimental impact on cardiorespiratory reserve. Determination of oxygen uptake at the anaerobic threshold by cardiopulmonary exercise testing (CPET) provides an objective measure of cardiorespiratory reserve. Anaerobic threshold can be used to predict perioperative risk. A low anaerobic threshold is associated with increased morbidity after oesophagogastrectomy. The aim of this study was to establish whether neoadjuvant chemotherapy has an adverse effect on fitness, and whether there is recovery of fitness before surgery for oesophageal and gastric adenocarcinoma. METHODS: CPET was completed before, immediately after (week 0), and at 2 and 4 weeks after neoadjuvant chemotherapy. The ventilatory anaerobic threshold and peak oxygen uptake (Vo2 peak) were used as objective, reproducible measures of cardiorespiratory reserve. Anaerobic threshold and Vo2 peak were compared before and after neoadjuvant chemotherapy, and at the three time intervals. RESULTS: Some 31 patients were recruited. The mean anaerobic threshold was lower following neoadjuvant treatment: 15.3 ml per kg per min before chemotherapy versus 11.8, 12.1 and 12.6 ml per kg per min at week 0, 2 and 4 respectively (P < 0.010). Measurements were also significantly different at each time point (P < 0.010). The same pattern was noted for Vo2 peak between values before chemotherapy (21.7 ml per kg per min) and at weeks 0, 2 and 4 (17.5, 18.6 and 19.3 ml per kg per min respectively) (P < 0.010). The reduction in anaerobic threshold and Vo2 peak did not improve during the time between completion of neoadjuvant chemotherapy and surgery. CONCLUSION: There was a decrease in cardiorespiratory reserve immediately after neoadjuvant chemotherapy that was sustained up to the point of surgery at 4 weeks after chemotherapy. PMID- 29601083 TI - Analysis of Episodes of Care in Medicare Beneficiaries Newly Diagnosed with Alzheimer's Disease. AB - OBJECTIVES: To study transitions between healthcare settings and quantify the cost burdens associated with different combinations of transitions during a 6 month period before initial Alzheimer's disease (AD) diagnosis so as to investigate how using an episode-of-care approach to payment for specific disease states might apply in AD. DESIGN: A retrospective observational cohort study. SETTING: United States. PARTICIPANTS: A random sample of 8,995 individuals aged 65 to 100 with a diagnosis of AD (International Classification of Diseases, Ninth Revision, Clinical Modification code 331.0) were identified from the Medicare database between January 1, 2011, and June 30, 2014. This analysis identified individuals with AD diagnosed in inpatient (18%), skilled nursing facility (SNF) (1%), hospice (4%), and home and outpatient (77%) settings and analyzed episodes that began in the index setting (defined as the care setting in which the individual was first diagnosed with AD). MEASUREMENTS: Study outcomes included number of transitions between settings, primary discharge diagnoses, and total all-cause healthcare costs during the 6 months after the AD diagnosis. RESULTS: The average numbers of transitions between care settings were 2.8 originating from an inpatient setting, 2.4 from a SNF, 0.3 from a hospice setting and 0.7 from a home or outpatient setting during 6 months post-AD diagnosis. The overall cost burden during the 6 months after AD diagnosis (including costs incurred at the index setting) was high for individuals diagnosed in a nonambulatory setting (mean $41,468). Individuals diagnosed in an ambulatory setting incurred only $12,597 in costs during the same period. CONCLUSION: Episodes of care can be defined and studied in individuals with AD. An episode-of-care approach to payment could encourage providers to use the continuum of care needed for quality medical management in AD more efficiently. PMID- 29601085 TI - The Gift. PMID- 29601084 TI - Elder Abuse and Chronic Pain: Cross-Sectional and Longitudinal Results from the Preventing Elder Abuse and Neglect Initiative. AB - OBJECTIVES: To examine the cross-sectional and longitudinal relationships between elder abuse and neglect (EAN) and chronic pain in rural older Malaysians. DESIGN: Two-year prospective cohort study. SETTING: Kuala Pilah, a district in Negeri Sembilan approximately 100 km from the capital city, Kuala Lumpur. PARTICIPANTS: Community-dwelling older adults aged 60 and older. Using a multistage cluster sampling strategy, 1,927 respondents were recruited and assessed at baseline, of whom 1,189 were re-assessed 2 years later. MEASURES: EAN was determined using the modified Conflict Tactic Scale, and chronic pain was assessed through self-report using validated questions. RESULTS: The prevalence of chronic pain was 20.4%. Cross-sectional results revealed 8 variables significantly associated with chronic pain-age, education, income, comorbidities, self-rated health, depression, gait speed, and EAN. Abused elderly adults were 1.52 times as likely to have chronic pain (odds ratio=1.52, 95% confidence interval (CI)=1.03-2.27), although longitudinal analyses showed no relationship between EAN and risk of chronic pain (risk ratio=1.14, 95% CI=0.81-1.60). This lack of causal link was consistent when comparing analysis with complete cases with that of imputed data. CONCLUSION: Our findings indicate no temporal relationship between EAN and chronic pain but indicated cross-sectional associations between the two. This might indicate that, although EAN does not lead to chronic pain, individuals with greater physical limitations are more vulnerable to abuse. Our study also shows the importance of cohort design in determining causal relationships between EAN and potentially linked health outcomes. PMID- 29601086 TI - SCN1A variants associated with sudden infant death syndrome. AB - We identified SCN1A variants in 2 infants who died of sudden infant death syndrome (SIDS) with hippocampal abnormalities from an exome sequencing study of 10 cases of SIDS but no history of seizures. One harbored SCN1A G682V, and the other had 2 SCN1A variants in cis: L1296M and E1308D, a variant previously associated with epilepsy. Functional evaluation in a heterologous expression system demonstrated partial loss of function for both G682V and the compound variant L1296M/E1308D. Our cases represent a novel association between SCN1A and SIDS, extending the SCN1A spectrum from epilepsy to SIDS. Our findings provide insights into SIDS and support genetic evaluation focused on epilepsy genes in SIDS. PMID- 29601087 TI - Construct and criterion validity testing of the Non-Technical Skills for Surgeons (NOTSS) behaviour assessment tool using videos of simulated operations. AB - BACKGROUND: Surgeons' non-technical skills are an important part of surgical performance and surgical education. The most widely adopted assessment tool is the Non-Technical Skills for Surgeons (NOTSS) behaviour rating system. Psychometric analysis of this tool to date has focused on inter-rater reliability and feasibility rather than validation. METHODS: NOTSS assessments were collected from two groups of consultant/attending surgeons in the UK and USA, who rated behaviours of the lead surgeon during a video-based simulated crisis scenario after either online or classroom instruction. The process of validation consisted of assessing construct validity, scale reliability and concurrent criterion validity, and undertaking a sensitivity analysis. Central to this was confirmatory factor analysis to evaluate the structure of the NOTSS taxonomy. RESULTS: Some 255 consultant surgeons participated in the study. The four category NOTSS model was found to have robust construct validity evidence, and a superior fit compared with alternative models. Logistic regression and sensitivity analysis revealed that, after adjusting for technical skills, for every 1-point increase in NOTSS score of the lead surgeon, the odds of having a higher versus lower patient safety score was 2.29 times. The same pattern of results was obtained for a broad mix of surgical specialties (UK) as well as a single discipline (cardiothoracic, USA). CONCLUSION: The NOTSS tool can be applied in research and education settings to measure non-technical skills in a valid and efficient manner. PMID- 29601089 TI - Reply. PMID- 29601088 TI - Blocking H1/H2 histamine receptors inhibits damage/fibrosis in Mdr2-/- mice and human cholangiocarcinoma tumorigenesis. AB - : Primary sclerosing cholangitis (PSC) patients are at risk of developing cholangiocarcinoma (CCA). We have shown that (1) histamine increases biliary hyperplasia through H1/H2 histamine receptors (HRs) and (2) histamine levels increase and mast cells (MCs) infiltrate during PSC and CCA. We examined the effects of chronic treatment with H1/H2HR antagonists on PSC and CCA. Wild-type and multidrug-resistant knockout (Mdr2-/- ) mice were treated by osmotic minipumps with saline, mepyramine, or ranitidine (10 mg/kg body weight/day) or a combination of mepyramine/ranitidine for 4 weeks. Liver damage was assessed by hematoxylin and eosin. We evaluated (1) H1/H2HR expression, (2) MC presence, (3) L-histidine decarboxylase/histamine axis, (4) cholangiocyte proliferation/bile duct mass, and (5) fibrosis/hepatic stellate cell activation. Nu/nu mice were implanted with Mz-ChA-1 cells into the hind flanks and treated with saline, mepyramine, or ranitidine. Tumor growth was measured, and (1) H1/H2HR expression, (2) proliferation, (3) MC activation, (4) angiogenesis, and (5) epithelial mesenchymal transition (EMT) were evaluated. In vitro, human hepatic stellate cells were evaluated for H1HR and H2HR expression. Cultured cholangiocytes and CCA lines were treated with saline, mepyramine, or ranitidine (25 MUM) before evaluating proliferation, angiogenesis, EMT, and potential signaling mechanisms. H1/H2HR and MC presence increased in human PSC and CCA. In H1/H2HR antagonist (alone or in combination)-treated Mdr2-/- mice, liver and biliary damage and fibrosis decreased compared to saline treatment. H1/H2HR antagonists decreased tumor growth, serum histamine, angiogenesis, and EMT. In vitro, H1/H2HR blockers reduced biliary proliferation, and CCA cells had decreased proliferation, angiogenesis, EMT, and migration. CONCLUSION: Inhibition of H1/H2HR reverses PSC associated damage and decreases CCA growth, angiogenesis, and EMT; because PSC patients are at risk of developing CCA, using HR blockers may be therapeutic for these diseases.

PMID- 29601091 TI - "To screen or not to screen": Comparing the health and economic benefits of early peanut introduction strategies in five countries. AB - BACKGROUND: Early peanut introduction (EPI) in the first year of life is associated with reduced risk of developing peanut allergy in children with either severe eczema and/or egg allergy. However, EPI recommendations differ among countries with formal guidelines. METHODS: Using simulation and Markov modeling over a 20-year horizon to attempt to explore optimal EPI strategies applied to the US population, we compared high-risk infant-specific IgE peanut screening (US/Canadian) with the Australiasian Society for Clinical Immunology and Allergy (Australia/New Zealand) (ASCIA) and the United Kingdom Department of Health (UKDOH)-published EPI approaches. RESULTS: Screening peanut skin testing of all children with early-onset eczema and/or egg allergy before in-office peanut introduction was dominated by a no screening approach, in terms of number of cases of peanut allergy prevented, quality-adjusted life years (QALY), and healthcare costs, although screening resulted in a slightly lower rate of allergic reactions to peanut per patient in high-risk children. Considering costs of peanut allergy in high-risk children, the per-patient cost of early introduction without screening over the model horizon was $6556.69 (95%CI, $6512.76-$6600.62), compared with a cost of $7576.32 (95%CI, $7531.38-$7621.26) for skin test screening prior to introduction. From a US societal perspective, screening prior to introduction cost $654 115 322 and resulted in 3208 additional peanut allergy diagnoses. Both screening and nonscreening approaches dominated deliberately delayed peanut introduction. CONCLUSIONS: A no-screening approach for EPI has superior health and economic benefits in terms of number of peanut allergy cases prevented, QALY, and total healthcare costs compared to screening and in-office peanut introduction. PMID- 29601092 TI - Different visual development: norms for visual acuity in children with Down's syndrome. AB - BACKGROUND: Visual acuity is known to be poorer in children with Down's syndrome than in age-matched controls. However, to date, clinicians do not have access to norms for children with Down's syndrome that allow differential discrimination of healthy from anomalous visual development in this population. METHODS: The Down's Syndrome Vision Research Unit at Cardiff University has been monitoring visual development in a large cohort of children since 1992. Cross-sectional data on binocular visual acuity were retrospectively analysed for 159 children up to 12 years of age in order to establish binocular acuity norms. Longitudinal binocular acuity data were available for nine children who were seen regularly over the 12 years age-range. Monocular acuity was successfully recorded less often in the cohort, but analysis of scores for 69 children allowed assessment of inter-ocular acuity differences and binocular summation. RESULTS: In comparison with published norms for the various acuity tests used, binocular acuity was consistently poorer in children with Down's syndrome from the age of three years and stabilised at around 0.25 logMAR from the age of four years. Inter-ocular acuity difference and binocular summation were both 0.06 logMAR, which is similar to the reported values in children without Down's syndrome. CONCLUSIONS: The study provides eye care practitioners with the expected values for binocular acuity in children with Down's syndrome and demonstrates the visual disadvantage that children with Down's syndrome have when compared with their typically developing peers. The results emphasise the responsibility that practitioners have to notify parents and educators of the relatively poor vision of children with Down's syndrome, and the need for classroom modifications. PMID- 29601093 TI - Cost-Effectiveness Analysis of Sacubitril/Valsartan for the Treatment of Heart Failure with Reduced Ejection Fraction in the United States. AB - OBJECTIVE: Sacubitril/valsartan (SAC/VAL) has been shown to reduce mortality and hospitalization in patients with heart failure with reduced ejection fraction (HFrEF) compared with enalapril but at a substantially higher cost. This study evaluates the cost-effectiveness of SAC/VAL versus enalapril in patients with HFrEF over a 5-year time horizon from the U.S. payer perspective. METHODS: A cohort-based Markov model was developed to compare costs and quality-adjusted life years (QALYs) between SAC/VAL and enalapril in patients with HFrEF over a 5 year time horizon. Markov states included New York Heart Association (NYHA) class (II-IV) and death. Treatment discontinuation, HF-related hospitalizations, and NYHA class progression were modeled as transition states based on data from the PARADIGM trial. Other probabilities, costs, and utilities were obtained from published literature and public databases. RESULTS: In the base case analysis, SAC/VAL cost more than enalapril ($81,943 vs $67,287) and was more effective (2.647 QALYs vs 2.546 QALYs), resulting in an incremental cost-effectiveness ratio of $143,891/QALY gained. At a willingness to pay (WTP) of $100,000/QALY, SAC/VAL was cost-effective up to a cost of $298/month. Results were most sensitive to SAC/VAL cost, SAC/VAL mortality benefit, and NYHA progression probability. SAC/VAL had a 10% and 52% probability of being cost-effective at WTP thresholds of $100,000/QALY and $150,000/QALY, respectively. CONCLUSIONS: SAC/VAL is associated with clinical benefit and may be cost-effective compared with the current standard of care over realistic treatment durations from the payer perspective. Results of this analysis can inform discussions on the value and position of SAC/VAL in the current market.

PMID- 29601096 TI - Frontline Science: Elevated nuclear lamin A is permissive for granulocyte transendothelial migration but not for motility through collagen I barriers. AB - Transendothelial migration (TEM) of lymphocytes and neutrophils is associated with the ability of their deformable nuclei to displace endothelial cytoskeletal barriers. Lamin A is a key intermediate filament component of the nuclear lamina that is downregulated during granulopoiesis. When elevated, lamin A restricts nuclear squeezing through rigid confinements. To determine if the low lamin A expression by leukocyte nuclei is critical for their exceptional squeezing ability through endothelial barriers, we overexpressed this protein in granulocyte-like differentiated HL-60 cells. A 10-fold higher lamin A expression did not interfere with chemokinetic motility of these granulocytes on immobilized CXCL1. Furthermore, these lamin A high leukocytes exhibited normal chemotaxis toward CXCL1 determined in large pore transwell barriers, but poorly squeezed through 3 MUm pores toward identical CXCL1 gradients. Strikingly, however, these leukocytes successfully completed paracellular TEM across inflamed endothelial monolayers under shear flow, albeit with a small delay in nuclear squeezing into their sub-endothelial pseudopodia. In contrast, CXCR2 mediated granulocyte motility through collagen I barriers was dramatically delayed by lamin A overexpression due to a failure of lamin A high nuclei to translocate into the pseudopodia of the granulocytes. Collectively, our data predict that leukocytes maintain a low lamin A content in their nuclear lamina in order to optimize squeezing through extracellular collagen barriers but can tolerate high lamin A content when crossing the highly adaptable barriers presented by the endothelial cytoskeleton. PMID- 29601097 TI - pTRAPs: Transmembrane adaptors in innate immune signaling. AB - Transmembrane adaptor proteins (TRAPs) are protein scaffolds and signaling regulators with established roles in signal-induced activation of lymphocytes. A subset of the TRAP family, the palmitoylated TRAPs (pTRAPs), are increasingly emerging with additional roles in innate immune cells. Targeted to lipid rafts, tetraspannin-enriched microdomains, and protein microclusters in membranes, pTRAP scaffolds exert spatiotemporal regulation by recruiting signaling kinases, particularly Src and Syk family members, as well as Csk, and other effectors. In this way, pTRAPs modulate signaling and influence resulting cell responses, including the selective output of inflammatory cytokines and other mediators. Here, we review studies revealing that different pTRAPs work together, often with overlapping or redundant roles, for positive and negative regulation of key innate immune pathways, including Fc receptor and pattern recognition receptor signaling. Recent findings show that pTRAPs can bind directly to innate immune receptors, in addition to other transmembrane binding partners. Thus, pTRAPs are important, multifunctional scaffolds in pathways that are fundamental to diverse innate immune responses.

PMID- 29601099 TI - Analytical validation of a flow cytometric protocol for quantification of platelet microparticles in dogs. AB - BACKGROUND: Platelet microparticles (PMPs) are subcellular procoagulant vesicles released upon platelet activation. In people with clinical diseases, alterations in PMP concentrations have been extensively investigated, but few canine studies exist. OBJECTIVES: This study aims to validate a canine flow cytometric protocol for PMP quantification and to assess the influence of calcium on PMP concentrations. METHODS: Microparticles (MP) were quantified in citrated whole blood (WB) and platelet-poor plasma (PPP) using flow cytometry. Anti-CD61 antibody and Annexin V (AnV) were used to detect platelets and phosphatidylserine, respectively. In 13 healthy dogs, CD61+ /AnV- concentrations were analyzed with/without a calcium buffer. CD61+ /AnV- , CD61+ /AnV+ , and CD61 /AnV+ MP quantification were validated in 10 healthy dogs. The coefficient of variation (CV) for duplicate (intra-assay) and parallel (inter-assay) analyses and detection limits (DLs) were calculated. RESULTS: CD61+ /AnV- concentrations were higher in calcium buffer; 841,800 MP/MUL (526,000-1,666,200) vs without; 474,200 MP/MUL (278,800-997,500), P < .05. In WB, PMP were above DLs and demonstrated acceptable (<20%) intra-assay and inter-assay CVs in 9/10 dogs: 1.7% (0.5-8.9) and 9.0% (0.9-11.9), respectively, for CD61+ /AnV- and 2.4% (0.2-8.7) and 7.8% (0.0-12.8), respectively, for CD61+ /AnV+ . Acceptable CVs were not seen for the CD61- /AnV+ MP. In PPP, quantifications were challenged by high inter assay CV, overlapping DLs and hemolysis and lipemia interfered with quantification in 5/10 dogs. CONCLUSIONS: Calcium induced higher in vitro PMP concentrations, likely due to platelet activation. PMP concentrations were reliably quantified in WB, indicating the potential for clinical applications. PPP analyses were unreliable due to high inter-CV and DL overlap, and not obtainable due to hemolysis and lipemia interference.

AB - The family of polypeptide N-acetylgalactosamine (GalNAc) transferases (GalNAc-Ts) orchestrates the initiating step of mucin-type protein O-glycosylation by transfer of GalNAc moieties to serine and threonine residues in proteins. Deficiencies and dysregulation of GalNAc-T isoenzymes are related to different diseases. Recently, it has been demonstrated that an inactive GalNAc-T2 mutant (F104S), which is not located at the active site, induces low levels of high density lipoprotein cholesterol (HDL-C) in humans. Herein, the molecular basis for F104S mutant inactivation has been deciphered. Saturation transfer difference NMR spectroscopy experiments demonstrate that the mutation induces loss of binding to peptide substrates. Analysis of the crystal structure of the F104S mutant bound to UDP-GalNAc (UDP=uridine diphosphate), combined with molecular dynamics (MD) simulations, has revealed that the flexible loop is disordered and displays larger conformational changes in the mutant enzyme than that in the wild type (WT) enzyme. 19 F NMR spectroscopy experiments reveal that the WT enzyme only reaches the active state in the presence of UDP-GalNAc, which provides compelling evidence that GalNAc-T2 adopts a UDP-GalNAc-dependent induced-fit mechanism. The F104S mutation precludes the enzyme from achieving the active conformation and concomitantly binding peptide substrates. This study provides new insights into the catalytic mechanism of the large family of GalNAc-Ts and how these enzymes orchestrate protein O-glycosylation. PMID- 29601102 TI - Frontline Science: Specialized proresolving lipid mediators inhibit the priming and activation of the macrophage NLRP3 inflammasome. AB - The prototypic proinflammatory cytokine IL-1beta plays a central role in innate immunity and inflammatory disorders. The formation of mature IL-1beta from an inactive pro-IL-1beta precursor is produced via nonconventional multiprotein complexes called the inflammasomes, of which the most common is the nucleotide binding domain leucine-rich repeat-containing protein 3 (NLRP3) inflammasome composed by NLRP3, (ASC) apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (CARD), and caspase-1. Specialized proresolving mediators (SPMs) promote resolution of inflammation, which is an essential process to maintain host health. SPMs prevent excessive inflammation by terminating the inflammatory response and returning to tissue homeostasis without immunosupression. This study tested the hypothesis that modulation of the NLRP3 inflammasome in macrophages is one mechanism involved in the SPM-regulated processes during resolution. Our findings demonstrate that the SPM resolvin D2 (RvD2) suppressed the expression of pro-IL-1beta and reduced the secretion of mature IL-1beta in bone marrow-derived macrophages challenged with LPS+ATP (classical NLRP3 inflammasome model) or LPS+palmitate (lipotoxic model). Similar findings were observed in thioglycolate-elicited peritoneal macrophages, in which RvD2 remarkably reduced ASC oligomerization, inflammasome assembly, and caspase-1 activity. In vivo, in a self-resolving zymosan A-induced peritonitis model, RvD2 blocked the NLRP3 inflammasome leading to reduced release of IL-1beta into the exudates, repression of osteopontin, and MCP-1 expression and induction of M2 markers of resolution (i.e., CD206 and arginase-1) in peritoneal macrophages. RvD2 inhibitory actions were receptor mediated and were abrogated by a selective GPR18 antagonist. Together, these findings support the hypothesis that SPMs have the ability to inhibit the priming and to expedite the deactivation of the NLRP3 inflammasome in macrophages during the resolution process. PMID- 29601101 TI - Regulation of immune cell signaling by activated protein C. AB - Innate immune cells are an essential part of the host defense response, promoting inflammation through release of proinflammatory cytokines or formation of neutrophil extracellular traps. While these processes are important for defense against infectious agents or injury, aberrant activation potentiates pathologic inflammatory disease. Thus, understanding regulatory mechanisms that limit neutrophil extracellular traps formation and cytokine release is of therapeutic interest for targeting pathologic diseases. Activated protein C is an endogenous serine protease with anticoagulant activity as well as anti-inflammatory and cytoprotective functions, the latter of which are mediated through binding cell surface receptors and inducing intracellular signaling. In this review, we discuss certain leukocyte functions, namely neutrophil extracellular traps formation and cytokine release, and the inhibition of these processes by activated protein C. PMID- 29601103 TI - Frontline Science: Characterization of a novel mouse strain expressing human Siglec-8 only on eosinophils. AB - Sialic acid-binding immunoglobulin-like lectin (Siglec)-8 is a human cell surface protein expressed exclusively on eosinophils, mast cells, and basophils that, when engaged, induces eosinophil apoptosis and inhibits mast cell mediator release. This makes Siglec-8 a promising therapeutic target to treat diseases involving these cell types. However, preclinical studies of Siglec-8 targeting in vivo are lacking because this protein is only found in humans, apes, and some monkeys. Therefore, we have developed a mouse strain in which SIGLEC8 transcription is activated by Cre recombinase and have crossed this mouse with the eoCre mouse to achieve eosinophil-specific expression. We confirmed that Siglec-8 is expressed exclusively on the surface of mature eosinophils in multiple tissues at levels comparable to those on human blood eosinophils. Following ovalbumin sensitization and airway challenge, Siglec-8 knock-in mice generated a pattern of allergic lung inflammation indistinguishable from that of littermate controls, suggesting that Siglec-8 expression within the eosinophil compartment does not alter allergic eosinophilic inflammation. Using bone marrow from these mice, we demonstrated that, during maturation, Siglec-8 expression occurs well before the late eosinophil developmental marker C-C motif chemokine receptor 3, consistent with eoCre expression. Antibody ligation of the receptor induces Siglec-8 endocytosis and alters the phosphotyrosine profile of these cells, indicative of productive signaling. Finally, we demonstrated that mouse eosinophils expressing Siglec-8 undergo cell death when the receptor is engaged, further evidence that Siglec-8 is functional on these cells. These mice should prove useful to investigate Siglec-8 biology and targeting in vivo in a variety of eosinophilic disease models. PMID- 29601104 TI - The impact of weight suppression and weight loss speed on baseline clinical characteristics and response to treatment. AB - OBJECTIVE: Growing evidence suggests an impact of weight suppression (WS) on severity and course of symptoms in patients with eating disorders (ED), but no study explored also the role of the weight loss speed (WLS) together with WS on the same clinical variables, which is the aim of the present work. METHOD: A mixed cross-sectional and longitudinal cohort study was employed. Four hundred and fourteen patients with anorexia nervosa (AN = 208) or bulimia nervosa (BN = 206) according to DSM-5 criteria were recruited and assessed at referral by means of clinical interviews and self-reported questionnaires. Body mass index and diagnostic status were re-evaluated at the end of treatment. RESULTS: WS was positively correlated with body dissatisfaction in patients with AN (p = .005), but negatively correlated in BN (p = .022). In contrast, WLS was significantly inversely correlated with age and duration of illness in all ED (p < .001), and positively correlated with drive for thinness in BN (p = .007). After treatment, WS at intake predicted higher BMI increase in both AN and BN (p < .03), while higher WLS was significantly associated with a lower drop-out rate in patients with BN (p = .02), and predicted BMI increase only in restricting AN patients (p = .02). In the whole group, WLS significantly predicted remission status (p = .039). DISCUSSION: In our study, both WS and WLS were associated with baseline "core" clinical variables and provided complementary abilities to predict weight gain and remission at the end of treatment. If replicated, our data suggest the importance of considering both WS and WLS as useful clinical variables in the baseline assessment of ED. PMID- 29601105 TI - Efficacy and Safety of Rituximab for the Treatment of Graves' Orbitopathy: A Meta analysis of Randomized Controlled Trials. AB - STUDY OBJECTIVE: To investigate the efficacy and safety of rituximab in patients with Graves' orbitopathy (GO). DESIGN: Systematic review and meta-analysis of four randomized controlled trials. PATIENTS: A total of 293 patients with GO who received rituximab or control (either glucocorticoids, the established first-line therapy [three trials], or saline [one trial]). MEASUREMENTS AND RESULTS: Relevant studies published before February 2018 were identified from the PubMed, EMBASE, Cochrane Library, and Scopus databases and the ClinicalTrials.gov registry. Individual effect sizes were standardized, and a meta-analysis was conducted to calculate the pooled effect size by using a random-effects model. Treatment efficacy was assessed by measuring the following outcomes: clinical activity score (CAS), sight visual acuity reduction (NOSPECS) score, proptosis, diplopia, changes in eye volume, quality of life, and adverse events. In the four included trials, 113 patients in the rituximab group and 108 patients in the control group were evaluated. Compared with the control group, CAS (weighted mean difference 0.57, 95% confidence interval 0.25-0.89) was significantly reduced at 24 weeks in the rituximab group. Compared with the control group, considerable proptosis reduction was also observed in the rituximab group; however, the difference was not significant. The proportion of adverse events in the rituximab group was not significantly higher than that in the glucocorticoid control group, but one of the included trials indicated that the rituximab group had more serious adverse events than the saline control group. CONCLUSION: Rituximab is a relatively safe and viable treatment that is superior to glucocorticoids or saline for patients with moderate to severe GO. However, the incidence of serious adverse events was disparate among the included trials. Additional studies involving a larger sample size and investigating the optimal rituximab dosage, frequency, and method of administration are warranted. PMID- 29601106 TI - Skin temperature in youth soccer players with functional equinus and non-equinus condition after running. AB - OBJECTIVES: To check how a thermal IR camera can check skin temperature in gastrocnemius-soleus equinus condition and non-gastrocnemius-soleus condition in youth soccer players and thus detect association between the extensibility of the triceps surae (with gastrocnemius-soleus equinus and non-gastrocnemius-soleus equinus) and the muscle temperature pattern. DESIGN: A cross-sectional study secondary level of care. METHODS: Sample from an elite soccer academy in Madrid (Spain) 35 healthy male subjects (youth soccer players) age 12.82 +/- 1.07 years, height 158.68 +/- 10.79 cm, weight 49.19 +/- 9.45 kg, body mass index 19.41 +/- 2.25. The exclusion criteria were the presence of musculoskeletal and joint injuries, pelvic pain, ankle sprains, low back pain and use of drugs in the previous week, and scoliosis. RESULTS: Temperature value for gastrocnemius muscles and Achilles tendon were assessed in 35 youth soccer players from an academia before and after training in both 12 gastrocnemius-soleus equinus and 23 non-gastrocnemius-soleus equinus soccer players conditions. State absolute for gastrocnemius soleus condition obtained a 0.34 value (0.19-0.5); we found a significant increase in temperature among these conditions for the gastrocnemius (P = 0.028) and the Achilles tendon (P = 0.007) (confidence interval 95%). The temperature of gastrocnemius-soleus equinus for gastrocnemius and Achilles tendon was increased more than non-gastrocnemius-soleus equinus in youth soccer players. CONCLUSIONS: IR imaging captured temperature is associated with muscle pattern activation for lower limb. Based on our findings, we propose that infrared thermography evaluation of the gastrocnemius and Achilles tendon is suitable to differ gastrocnemius-soleus equinus and non-gastrocnemius-soleus equinus conditions in youth soccer players. PMID- 29601107 TI - Characterization of a chimeric chemokine as a specific ligand for ACKR3. AB - Chemokines, small chemotactic cytokines, orchestrate cell migration by binding to their cognate chemokine receptors. While chemokine-mediated stimulation of typical G-protein-coupled chemokine receptors leads to cell migration, binding of chemokines to atypical chemokine receptors (ACKRs) does not induce canonical signaling. ACKRs are considered important chemokine scavengers, that can create gradients which help direct cells to sites of inflammation or to their immunological niches. Synthetic chemokines have been used in the past to study and decode chemokine-receptor interactions. Characterizing specific chemokine ACKRs interactions is challenging because the chemokines bind multiple receptors; for example, the ACKR3 ligands CXCL12 and CXCL11 bind to the canonical receptors CXCR4 and CXCR3, respectively. Here, we present the engineering of a chemokine like chimera, which selectively binds to ACKR3. The addition of a ybbR13 tag at the C-terminus allows site specific enzymatic labeling with a plethora of fluorescent dyes. The chimera is composed of the N-terminus of CXCL11 and the main body and C-terminus of CXCL12 and selectively interacts with ACKR3 with high affinity, while not interfering with binding of CXCL11 and CXCL12 to their cognate receptors. We further provide evidence that the chimera can be used to study ACKR3 function in vivo. PMID- 29601108 TI - Synthesis of Avibactam Derivatives and Activity on beta-Lactamases and Peptidoglycan Biosynthesis Enzymes of Mycobacteria. AB - There is a renewed interest for beta-lactams for treating infections due to Mycobacterium tuberculosis and M. abscessus because their beta-lactamases are inhibited by classical (clavulanate) or new generation (avibactam) inhibitors, respectively. Here, access to an azido derivative of the diazabicyclooctane (DBO) scaffold of avibactam for functionalization by the Huisgen-Sharpless cycloaddition reaction is reported. The amoxicillin-DBO combinations were active, indicating that the triazole ring is compatible with drug penetration (minimal inhibitory concentration of 16 MUg mL-1 for both species). Mechanistically, beta lactamase inhibition was not sufficient to account for the potentiation of amoxicillin by DBOs. Thus, the latter compounds were investigated as inhibitors of l,d-transpeptidases (Ldts), which are the main peptidoglycan polymerases in mycobacteria. The DBOs acted as slow-binding inhibitors of Ldts by S carbamoylation indicating that optimization of DBOs for Ldt inhibition is an attractive strategy to obtain drugs selectively active on mycobacteria. PMID- 29601109 TI - Fungal diseases in children and adolescents in a referral centre in Bogota, Colombia. AB - A cross-sectional descriptive study was conducted at a dermatology referral centre in Bogota, to estimate the frequencies and aetiologies of mycoses in the population under 18 years of age attending the medical mycology laboratory over a 13-year period (2000-2012). A total of 1337 samples from 1221 patients were evaluated, involving direct examination and culture for 1279 samples, direct examination alone for 50 and culture alone for 8. During the study period, dermatophytosis was diagnosed via culture in 537 cases (40.1%). The most common aetiological agents were Trichophyton rubrum (235 cases), Microsporum canis (177), Trichophyton mentagrophytes (74) and Microsporum gypseum (22). Pityriasis versicolor was found in 31 cases (5.1%), Candida spp. were found in 17 cases, and non-dermatophyte moulds were confirmed by a second sample in 6 cases (3 cases involving Fusarium spp., 2 Neoscytalidium dimidiatum and 1 Acremonium spp.). In addition, white piedra was diagnosed in 4 cases (0.7%), and tinea nigra in 2 cases (0.3%). Regarding subcutaneous mycoses, 14 cases of sporotrichosis were identified. The results from this study confirm the predominance of dermatophytosis in the paediatric population. T. rubrum and M. canis were the main aetiological agents. We found a few cases of onychomycosis by non dermatophyte moulds. Sporotrichosis was the only subcutaneous mycosis diagnosed during the study period. PMID- 29601112 TI - Cerebral perfusion characteristics show differences in younger versus older children with sickle cell anaemia: Results from a multiple-inflow-time arterial spin labelling study. AB - Sickle cell anaemia (SCA) is associated with chronic anaemia and oxygen desaturation, which elevate cerebral blood flow (CBF) and increase the risk of neurocognitive complications. Arterial spin labelling (ASL) provides a methodology for measuring CBF non-invasively; however, ASL techniques using only a single inflow time are not sufficient to fully characterize abnormal haemodynamic behaviour in SCA. This study investigated haemodynamic parameters from a multi-inflow-time ASL acquisition in younger (8-12 years) and older (13-18 years) children with SCA with and without silent cerebral infarction (SCI+/-) (n = 20 and 19 respectively, 6 and 4 SCI+ respectively) and healthy controls (n = 9 and 7 respectively). Compared with controls, CBF was elevated globally in both groups of patients. In the younger SCA patients, blood oxygen content was negatively correlated with CBF in the middle and posterior cerebral artery territories and significantly positively correlated with bolus arrival time (BAT) in the anterior and middle cerebral artery territories. In older children, SCA patients had significantly shorter BAT than healthy controls and there was a significant negative correlation between CBF and oxygen content only in the territory of the posterior cerebral artery, with a trend for a correlation in the anterior cerebral artery but no relationship for the middle cerebral artery territory. In the younger group, SCI+ patients had significantly higher CBF in the posterior cerebral artery territory (SCI+ mean = 92.78 ml/100 g/min; SCI- mean = 72.71 ml/100 g/min; F = 4.28, p = 0.04), but this no longer reached significance when two children with abnormal transcranial Doppler and one with haemoglobin SC disease were excluded, and there were no significant differences between patients with and without SCI in the older children. With age, there appears to be increasing disparity between patients and controls in terms of the relationship between CBF and oxygen content in the anterior circulation, potentially predicting the risk of acute and chronic compromise of brain tissue. PMID- 29601110 TI - Expression of novel "LOCGEF" isoforms of ARHGEF18 in eosinophils. AB - Genomic, transcriptomic and proteomic databases indicate that the N-terminal 322 residues encoded by the presumptive LOC100996504 gene, which is adjacent to the ARHGEF18 guanine nucleotide exchange factor gene on chromosome 19, constitute the N-terminal portion of a 1361-residue isoform of ARHGEF18, dubbed LOCGEF-X3. LOCGEF-X3 arises from the use of a leukocyte-specific alternative transcriptional start site and splicing that bypasses the initial noncoding exon of the canonical 1015-residue ARHGEF18 isoform, p114. Eosinophil LOCGEF-X3 was amplified and cloned, recombinant LOCGEF-X3 was expressed, and anti-ARHGEF18 antibody was found to recognize a band in immunoblots of eosinophil lysates that co-migrates with recombinant LOCGEF-X3. PCR of eosinophils revealed minor amounts of transcripts for X4 and X5 isoforms of LOCGEF that arise from differential splicing and differ from the X3 isoform at their extreme N-termini. No p114 transcript or protein band was detected in eosinophils. Immunostaining with anti-ARHGEF18 antibody revealed relocalization of LOCGEF and RHOA from the periphery of round unstimulated eosinophils to the 2 poles of eosinophils polarized by treatment with IL5, CCL11, or IL33 in suspension. Canonical p114 ARHGEF18 has been implicated in maintenance of epithelial cell polarity. We suggest that the "LOC" portion of LOCGEF, which is unlike any other protein domain, has unique functions in control of polarity in activated eosinophils and other leukocytes. PMID- 29601111 TI - Oscillating gradient diffusion kurtosis imaging of normal and injured mouse brains. AB - Recent advances in diffusion MRI employ multiple diffusion encoding schemes with varying diffusion direction, weighting, and diffusion time to investigate specific microstructural properties in biological tissues. In this study, we examined time-dependent diffusion kurtosis contrast in adult mouse brains and in neonatal mouse brains after hypoxic-ischemic (HI) injury. In vivo diffusion kurtosis maps were acquired with a short diffusion time using an oscillating gradient spin echo (OGSE) sequence at 100 Hz and with a relatively long diffusion time (20 ms) using a pulsed gradient spin echo (PGSE) sequence. In the adult mouse brain, we found that the cortex and hippocampus showed larger differences between OGSE kurtosis and PGSE kurtosis than major white matter tracts. In neonatal mouse brains with unilateral HI injury, the OGSE kurtosis map overall provided stronger edema contrast than the PGSE kurtosis map, and the differences between OGSE and PGSE kurtosis measurements in the edema region reflected heterogeneity of injury. This is the first in vivo study that has demonstrated multi-direction OGSE kurtosis contrasts in the mouse brain. Comparing PGSE and OGSE kurtosis measures may provide additional information on microstructural changes after ischemic stroke. PMID- 29601113 TI - Directional Self-Sorting with Cucurbit[8]uril Controlled by Allosteric pi-pi and Metal-Metal Interactions. AB - To maximize Coulombic interactions, cucurbit[8]uril (CB[8]) typically forms ternary complexes that distribute the positive charges of the pair of guests (if any) over both carbonylated portals of the macrocycle. We present here the first exception to this recognition pattern. Platinum(II) acetylides flanked by 4' substituted terpyridyl ligands (tpy) form 2:1 complexes with CB[8] in an exclusively stacked head-to-head orientation in a water/acetonitrile mixture. The host encapsulates the pair of tpy substituents, and both positive Pt centers sit on top of each other at the same CB[8] rim, leaving the other rim free of any interaction with the guests. This dramatic charge imbalance between the CB[8] rims would be electrostatically penalizing, were it not for allosteric pi-pi interactions between the stacked tpy ligands, and possible metal-metal interactions between both Pt centers. When both tpy and acetylides are substituted with aryl units, the metal-ligand complexes form 2:2 assemblies with CB[8] in aqueous medium, and the directionality of the assembly (head-to-head or head-to-tail) can be controlled, both kinetically and thermodynamically. PMID- 29601114 TI - Analysis and improvement of motion encoding in magnetic resonance elastography. AB - Magnetic resonance elastography (MRE) utilizes phase contrast magnetic resonance imaging (MRI), which is phase locked to externally generated mechanical vibrations, to measure the three-dimensional wave displacement field. At least four measurements with linear-independent encoding directions are necessary to correct for spurious phase contributions if effects from imaging gradients are non-negligible. In MRE, three encoding schemes have been used: unbalanced four- and six-point and balanced four-point ('tetrahedral') encoding. The first two sensitize to motion with orthogonal gradients, with the four-point method acquiring a single reference scan without motion sensitization, whereas three additional scans with inverted gradients are used with six-point encoding, leading to two-fold higher displacement-to-noise ratio (DNR) and 50% longer scan duration. Balanced four-point (tetrahedral) encoding encodes along the four diagonals of a cube, with one direction serving as a reference for the other three encoding directions, similar to four-point encoding. The objective of this work is to introduce a theoretical framework to compare different motion sensitization strategies with respect to their motion encoding efficiency in two fundamental encoding limits, the gradient strength limit and the dynamic range limit, which are both placed in relation to conventional gradient recalled echo (GRE)- and spin echo (SE)-based MRE sequences. We apply the framework to the three aforementioned schemes and show that the motion encoding efficiency of unbalanced four- and six-point encoding schemes in the gradient-limited regime can be increased by a factor of 1.5 when using all physical gradient channels concurrently. Furthermore, it is demonstrated that reversing the direction of the reference in balanced four-point (tetrahedral) encoding results in the Hadamard encoding scheme, which leads to increased DNR by 2 compared with balanced four point encoding and 2.8 compared with unbalanced four-point encoding. As an example, we show that optimal encoding can be utilized to reduce the acquisition time of standard liver MRE in vivo from four to two breath holds.

PMID- 29601115 TI - Long-Term Beta-Blocker Therapy after Myocardial Infarction in the Reperfusion Era: A Systematic Review. AB - Beta-blockers are recommended as standard of care for patients who experience a myocardial infarction (MI). However, evidence to support this recommendation is primarily derived from the pre-reperfusion era. In the reperfusion era, short term (<= 30 days) beta-blocker therapy has been demonstrated to reduce recurrent MI and angina, but not mortality. The objective of this review was to evaluate the evidence for long-term (>= 1 yr) beta-blocker therapy in patients post-MI without left ventricular dysfunction in the reperfusion era. A systematic search of MEDLINE, EMBASE, CENTRAL, and Google from inception to September 2017 was performed. Included were randomized controlled trials and observational propensity score cohort studies published within the past 10 years that compared beta-blockers to placebo/no beta-blockers at discharge in patients with an acute MI but without left ventricular dysfunction or heart failure. Outcomes of interest included all-cause and cardiovascular mortality, nonfatal MI, and nonfatal stroke. Eight cohort studies were included. Follow-up ranged from 1 to 5 years. Two smaller studies demonstrated a reduction in all-cause mortality with beta-blockers, whereas there was no difference observed in six studies. One study showed reduced cardiovascular mortality at 1 year, but no difference in sudden cardiac death. One study demonstrated a reduction in cardiac mortality at 3 years, but no difference in MI or stroke. None of the four studies that reported adverse cardiovascular events demonstrated a benefit with beta-blocker therapy. Though these data are limited by observational methodology, the majority of the included studies failed to demonstrate a benefit in survival or cardiovascular events with long-term beta-blockers in post-MI patients with normal left ventricular function. In the absence of a contemporary randomized controlled trial, this evidence imparts uncertainty regarding the current standard of care and suggests that it may be reasonable to discontinue beta-blockers in patients without impaired left ventricular function at 1-year post-MI who do not have another indication for use.

AB - Ab initio DFT computations reveal that the essential structural and photophysical features of the conjugated pi-electron system of retinal and carotenoids are dictated by "innocent" methyl substituents. These methyl groups shape the conformation and symmetry of the isoprenoid chromophores by causing a sigmoidal distortion of the polyene skeleton and increasing its flexibility, which facilitates fitting to their binding pockets in proteins. Comparison of in vacuo conformations of the chromophores with their native (protein-bound) conformations showed, surprisingly, that the peripheral groups and interactions with the protein environment are much less significant than the methyl side groups in tuning their structural features. The methyl side groups also contribute to a loss of symmetry elements specific to linear polyenes. In effect, the symmetry imposed restrictions on the chromophore electronic properties are disabled, which is of tremendous relevance to their photophysics. This is evidenced by their non negligible permanent dipole moments and by the simulated and experimentally measured circular dichroism spectra, which necessarily reflect the chirality of the conjugated pi-electron system. PMID- 29601119 TI - Employing an Unsaturated Th4+ Site in a Porous Thorium-Organic Framework for Kr/Xe Uptake and Separation. AB - Actinide based metal-organic frameworks (MOFs) are unique not only because compared to the transition-metal and lanthanide systems they are substantially less explored, but also owing to the uniqueness of actinide ions in bonding and coordination. Now a 3D thorium-organic framework (SCU-11) contains a series of cages with an effective size of ca. 21*24 A. Th4+ in SCU-11 is 10-coordinate with a bicapped square prism coordination geometry, which has never been documented for any metal cation complexes. The bicapped position is occupied by two coordinated water molecules that can be removed to afford a very unique open Th4+ site, confirmed by X-ray diffraction, color change, thermogravimetry, and spectroscopy. The degassed phase (SCU-11-A) exhibits a Brunauer-Emmett-Teller surface area of 1272 m2 g-1 , one of the highest values among reported actinide materials, enabling it to sufficiently retain water vapor, Kr, and Xe with uptake capacities of 234 cm3 g-1 , 0.77 mmol g-1 , 3.17 mmol g-1 , respectively, and a Xe/Kr selectivity of 5.7. PMID- 29601120 TI - Increased centrosome number in BRCA-related breast cancer specimens determined by immunofluorescence analysis. AB - BRCA-related breast carcinoma can be prevented through prophylactic surgery and an intensive follow-up regimen. However, BRCA genetic tests cannot be routinely performed, and some BRCA mutations could not be defined as deleterious mutations or normal variants. Therefore, an easy functional assay of BRCA will be useful to evaluate BRCA status. As it has been reported that BRCA functions in the regulation of centrosome number, we focused on centrosome number in cancer tissues. Here, 70 breast cancer specimens with known BRCA status were analyzed using immunofluorescence of gamma-tubulin (a marker of centrosome) foci. The number of foci per cell was higher in cases with BRCA mutation compared to wild type cases, that is, 1.9 (95% confidence interval [CI], 1.5-2.3) vs 0.5 (95% CI, 0.2-0.8) (P < .001). Specifically, foci numbers per cell in BRCA1 and BRCA2 mutation cases were 1.2 (95% CI, 0.6-1.8) and 2.2 (95% CI, 1.7-2.6), respectively, both higher than those in wild-type cases (P = .042 and P < .0001, respectively). The predictive value of gamma-tubulin foci as determined by area under the curve (AUC = 0.86) for BRCA status was superior to BRCAPRO (AUC = 0.69), Myriad Table (AUC = 0.61), and KOHBRA BRCA risk calculator (AUC = 0.65) pretest values. The use of gamma-tubulin foci to predict BRCA status had sensitivity = 83% (19/23), specificity = 89% (42/47), and positive predictive value = 77% (20/26). Thus, gamma-tubulin immunofluorescence, a functional assessment of BRCA, can be used as a new prospective test of BRCA status. PMID- 29601121 TI - PAI-1 induces Src inhibitor resistance via CCL5 in HER2-positive breast cancer cells. AB - Tyrosine kinase Src is overexpressed and activated in various tumors, including breast cancer, and is supposed to promote cancer formation and development. Src inhibitors have been developed recently and have shown efficacy in breast cancer as a single agent or in combination with anti-HER2 antibodies or chemotherapy. Unfortunately, the potency of Src inhibitor is limited by the development of drug resistance. In our study, we established an Src inhibitor saracatinib-resistant breast cancer cell line (SKBR-3/SI) for the first time and by evaluating mRNA expression profile, we found that plasminogen activator inhibitor-1 (PAI-1) was upregulated in saracatinib-resistant cells compared to the parent cells. Further study demonstrated that PAI-1 might induce saracatinib resistance in breast cancer cells by increasing the secretion of chemokine (C-C motif) ligand 5 (CCL5). Functional assays showed that PAI-1 and CCL5 overexpression promoted cell proliferation and migration in breast cancer cells, while inhibition of PAI-1 and CCL5 decreased cell proliferation and migration in saracatinib-resistant cells. We also showed that targeting PAI-1 or CCL5 could reverse saracatinib resistance, which deserves more attention in clinical settings. PMID- 29601122 TI - Oncologic outcomes of surgical treatment for T3 glottic laryngeal squamous cell carcinoma. AB - BACKGROUND: The purpose of this study was to assess the clinical results of patients with T3 glottic laryngeal carcinoma treated with total laryngectomy or partial laryngectomy. METHODS: We conducted a retrospectively review of 307 patients with T3 glottic laryngeal squamous cell carcinoma (SCC). RESULTS: The 5 year cancer-specific survival (CSS) rate was 71.5% and the overall survival (OS) rate was 70.6%. For patients who underwent total laryngectomy, the 5-year disease free survival (DFS) rate was 59.8%, and the CSS rate was 67.9%. For partial laryngectomy, the 5-year DFS rate was 64.8%, and the CSS rate was 78.0%. High lymph node and stage status are predictors of mortality for these patients. No difference was found in DFS and CSS rates between patients with negative margins and those with positive margins after postoperative radiotherapy and chemotherapy. CONCLUSION: Postoperative radiotherapy and chemotherapy are effective treatments for patients with T3 glottic laryngeal carcinoma, especially with a positive margin. For selected patients with T3 glottic laryngeal carcinoma, partial laryngectomy is a good choice because it can achieve satisfactory oncologic results while preserving laryngeal function.

AB - A series of three europium complexes bearing picolyl amine moieties was found to possess differing binding affinities towards Zn2+ and three nucleotides: AMP, ADP, and ATP. A large increase in the total emission intensity was observed upon binding Zn2+ , followed by signal amplification upon the addition of nucleotides. The resulting adducts possessed strong induced circularly polarised emission, with ADP and ATP signals of opposite sign. Model DFT geometries of the adducts suggest the Delta diastereoisomer is preferred for ATP and the Lambda isomer for ADP/AMP. This change in sign allows the ADP/ATP (or AMP/ATP) ratio to be assessed by monitoring changes in the emission dissymmetry factor, gem .

AB - High-Ni layered oxides are promising next-generation cathodes for lithium-ion batteries owing to their high capacity and lower cost. However, as the Ni content increases over 70 %, they have a high dynamic affinity towards moisture and CO2 in ambient air, primarily reacting to form LiOH, Li2 CO3 , and LiHCO3 on the surface, which is commonly termed "residual lithium". Air exposure occurs after synthesis as it is common practice to handle and store them under ambient conditions. The air exposure leads to significant performance losses, and hampers the electrode fabrication, impeding their practical viability. Herein, we show that substituting a small amount of Al for Ni in the crystal lattice notably improves the chemical stability against air by limiting the formation of LiOH, Li2 CO3 , LiHCO3 , and NiO in the near-surface region. The Al-doped high-Ni oxides display a high capacity retention with excellent rate capability and cycling stability after being exposed to air for 30 days.

AB - An increasing number of studies have established hydrogen sulfide (H2 S) gas as a major cytoprotectant and redox modulator. Following its discovery, H2 S has been found to have pleiotropic effects on physiology and human health. H2 S acts as a gasotransmitter and exerts its influence on gastrointestinal, neuronal, cardiovascular, respiratory, renal, and hepatic systems. Recent discoveries have clearly indicated the importance of H2 S in regulating vasorelaxation, angiogenesis, apoptosis, ageing, and metabolism. Contrary to studies in higher organisms, the role of H2 S in the pathophysiology of infectious agents such as bacteria and viruses has been less studied. Bacterial and viral infections are often accompanied by changes in the redox physiology of both the host and the pathogen. Emerging studies indicate that bacterial-derived H2 S constitutes a defense system against antibiotics and oxidative stress. The H2 S signaling pathway also seems to interfere with redox-based events affected on infection with viruses. This review aims to summarize recent advances on the emerging role of H2 S gas in the bacterial physiology and viral infections. Such studies have opened up new research avenues exploiting H2 S as a potential therapeutic intervention.

PMID- 29601126 TI - Expression of cytosolic malic enzyme (ME1) is associated with disease progression in human oral squamous cell carcinoma. AB - Malic enzyme 1 (ME1) is a multifunctional protein involved in glycolysis, the citric acid cycle, NADPH production, glutamine metabolism, and lipogenesis. It is overexpressed in various cancers. We examined the expression of ME1 in 119 oral squamous cell carcinomas (OSCCs) using immunohistochemistry. Malic enzyme 1 expression was moderate to strong in 57 (48%) OSCCs and correlated with pT, pN, clinical stage, and histological grade. In 37 cases with prognostic evaluation, moderate to strong ME1 expression indicated a worse prognosis than did weak ME1 expression. Malic enzyme 1 knockdown or inactivation by lanthanide inhibited cell proliferation and motility and suppressed the epithelial-mesenchymal transition in HSC3 human OSCC cells. Knockdown of ME1 also shifted energy metabolism from aerobic glycolysis and lactate fermentation to mitochondrial oxidative phosphorylation, and the redox status from reductive to oxidative. In a mouse tumor model, lanthanide suppressed tumor growth and increased survival time. These findings reveal that ME1 is a valid target for molecular therapy in OSCC.

AB - Liver fibrosis is an excessively reversible wound healing process and the fibrotic disorder is the activation of hepatic stellate cell that requires extensive alterations in gene expression. As reversible deacetylation of histone proteins modulate gene expression, we examined the effect of valproic acid (VPA) as selective histone deacetylase inhibitor on CCl-4 induced liver fibrosis. Thirty rats were divided into three equal groups; control group, fibrotic group and VPA-treated group. The rats were sacrificed after 6 weeks of liver fibrosis induction. The histopathological effect on liver tissue was examined. The expression of alpha-SMA and Smad-4 mRNA and serum levels of TGF-beta1, alanine aminotransferase, and aspartate aminotransferase were determined. Treatment of rats with VPA attenuated carbon tetrachloride-induced liver fibrosis. Moreover, alpha-SMA and Smad-4 expression was repressed under VPA treatment and both serum TGF-beta1 and liver enzymes were significantly decreased. The histone deacetylase inhibitor-1 VPA inhibits the epithelial-mesenchymal transition and affects hepatic stellate cell activation during liver fibrosis through downregulation of Smad4 and alpha-SMA expression which may serve as a promising agent in liver fibrosis treatment.

AB - Metastasis to distant organs is a particularly ominous feature of malignant cancer. LKB1 (also known as STK11) has been identified as a tumor suppressor in several types of cancers. Here, we show that LKB1 is at low levels and is negatively associated with poor clinical outcomes in pancreatic cancer (PC). LKB1 is inversely correlated with Snail protein in PC, in which the loss of LKB1 facilitates metastasis through elevating Snail protein level. Furthermore, LKB1 boosts Snail's interaction with E3 ligase FBXL14, leading to increasing ubiquitin mediated Snail degradation. Notably, metformin could increase Snail protein ubiquitination via augmenting the location of LKB1 at cytoplasm as well as increasing LKB1 expression. Altogether, our data established that LKB1 impedes invasion and metastasis by decreasing the Snail protein level in PC. Targeting the LKB1/FBXL14/Snail axis may represent a promising therapeutic strategy and metformin might be beneficial for PC therapy through activating the LKB1-mediated Snail ubiquitination pathway. PMID- 29601130 TI - Halogen-Aromatic pi Interactions Modulate Inhibitor Residence Times. AB - Prolonged drug residence times may result in longer-lasting drug efficacy, improved pharmacodynamic properties, and "kinetic selectivity" over off-targets with high drug dissociation rates. However, few strategies have been elaborated to rationally modulate drug residence time and thereby to integrate this key property into the drug development process. Herein, we show that the interaction between a halogen moiety on an inhibitor and an aromatic residue in the target protein can significantly increase inhibitor residence time. By using the interaction of the serine/threonine kinase haspin with 5-iodotubercidin (5-iTU) derivatives as a model for an archetypal active-state (type I) kinase-inhibitor binding mode, we demonstrate that inhibitor residence times markedly increase with the size and polarizability of the halogen atom. The halogen-aromatic pi interactions in the haspin-inhibitor complexes were characterized by means of kinetic, thermodynamic, and structural measurements along with binding-energy calculations. PMID- 29601131 TI - Pathological tumor regression grade of metastatic tumors in lymph node predicts prognosis in esophageal cancer patients. AB - Tumor regression grade of the primary tumor (TRG-PT) and residual lymph node metastasis have been pathologically determined in esophageal squamous cell carcinoma (ESCC) patients who had received neoadjuvant chemotherapy (nCT) followed by surgery; however, TRG of the metastatic tumor involving lymph nodes (LN) has not yet been determined. The aim of the present study was to clarify the impact of TRG on the prognosis of ESCC patients. ESCC patients (n = 110) who had received nCT followed by surgery were enrolled. Dissected LN were classified into 2 categories: plausible positive metastatic LN (pp-MLN) where viable and/or degenerated ESCC cells and/or tissue modifications were observed, and non metastatic LN (non-MLN) where neither of them was observed. We defined nCT effective rate (CER) as the ratio of the number of pp-MLN that showed tumor regression to the total number of pp-MLN, and divided CER into low-CER (LCER; >=0% and <50%) and high-CER (HCER; >=50% and <=100%). Relationships between CER and clinicopathological factors including prognosis were then examined. Multivariate analyses of 110 patients indicated that ypT3-4 (P = .023, HR; 2.551), positive venous infiltration (P = .006, HR; 3.526), and LCER (P = .033, HR; 1.922) were independently associated with shorter recurrence-free survival (RFS). Multivariate analyses of 43 patients with grade 0 TRG-PT showed that ypT3 4 (P = .033, HR; 3.397) and LCER (P = .008, HR; 3.543) were independently associated with shorter RFS. This study showed that CER was one of the prognostic factors for ESCC patients who had received nCT followed by surgery. PMID- 29601132 TI - Full Conformational Landscape of 3-Methoxyphenol Revealed by Room Temperature mm wave Rotational Spectroscopy Supported by Quantum Chemical Calculations. AB - Room temperature millimeter-wave rotational spectroscopy supported by high level of theory calculations have been employed to fully characterise the conformational landscape of 3-Methoxyphenol, a semi-volatile polar oxygenated aromatic compound precursor of secondary organic aerosols in the atmosphere arising from biomass combustion. While previous rotationally-resolved spectroscopic studies in the microwave and in the UV domains failed to observe the complete conformational landscape, the 70-330 GHz rotational spectrum measured in this study reveals the ground state rotational signatures of the four stable conformations theoretically predicted. Moreover, rotational transitions in the lowest energy vibrationally excited states were assigned for two conformers. While the inertial defect of methoxyphenol does not significantly change between conformers and isomers, the excitation of the methoxy out-of-plane bending is the main contribution to the non-planarity of the molecule. PMID- 29601133 TI - All-Optical Switching and Two-States Light-Controlled Coherent-Incoherent Random Lasing in a Thiophene-Based Donor-Acceptor System. AB - We describe herein the synthesis and characterization of a thiophene-based donor acceptor system, namely (E)-2-(4-nitrostyryl)-5-phenylthiophene (Th-pNO2 ), which was prepared under Horner-Wadsworth-Emmons conditions. The UV/Vis absorption bands, including the intramolecular charge transfer (ICT) band, were fully assigned using DFT and TD-DFT computations. The results of both efficient third order nonlinear optical properties and light-amplification phenomena are presented. Investigations of photoinduced birefringence (PIB) in optical Kerr effect (OKE) experiments showed a great potential for this particular compound as an efficient, fully reversible, and fast optical switch. Time constants for the observed trans-cis-trans molecular transitions are in the range of microseconds and give a competitive experimental result for the well-known and exploited azobenzene derivatives. Random lasing (RL) investigations confirmed that this organic system is potentially useful to achieve strong light enhancement, observed as a multimode lasing action. Both RL and OKE measurements indicate that this material is a representative of thiophene derivatives, which can be utilized to fabricate fast all-optical switches or random lasers (light amplifiers).

AB - The coordination of PySSPy to FePc was monitored by UV/Vis spectroscopy while the adsobed FePc, anchored by PyS-Au(111), was examined by in situ STM in 0.1 M HClO4 and X-ray photoelectron spectroscopy (XPS). Rotating-disc-electrode (RDE) and linear-sweep-voltammetry (LSV) studies on the resulting FePc-modified Au(111) electrodes in an oxygen-saturated 0.1 M NaOH electrolyte exhibit excellent electrocatalytic properties for the oxygen reduction reaction (ORR), with a smaller overpotential than that observed for Au(111) with FePc deposited by direct adsorption from a benzene solution. PMID- 29601135 TI - Effects of knee loading on obesity-related non-alcoholic fatty liver disease in an ovariectomized mouse model with high-fat diet. AB - AIM: Hormonal and nutritional disorders are the main causes of obesity and non alcoholic fatty liver disease, especially in the elderly and in postmenopausal women. Although physical activity might alleviate these disorders, the elderly may often have difficulty in carrying out physical exercise. The purpose of this study was to investigate the therapeutic effect of knee loading, a new form of physical stimulation, on the symptoms of obesity and fatty liver. METHODS: Using ovariectomized mice fed a high-fat diet, we evaluated the effect of knee loading that applies gentle cyclic loads to the knee. Female C57BL/6 mice were divided into five groups: control (SCD), high-fat diet (HF), HF with loading (HF + L), HF with ovariectomy (HF + OVX), and HF + OVX with loading (HF + OVX + L). Except for SCD, mice underwent sham operation or ovariectomy and were maintained on HF diet. After 6 weeks, the mice in the HF + L and HF + OVX + L groups were treated with knee loading for 6 weeks. RESULTS: Compared to the obesity groups (HF and HF + OVX), knee loading significantly decreased a gain in body weight, liver weight, and white adipose tissue (all P < 0.01). It also reduced the lipid level in the serum (P < 0.01) and histological severity of hepatic steatosis (P < 0.01). Furthermore, knee loading downregulated biomarkers related to endoplasmic reticulum (ER) stress (GRP78, p-eIF2alpha, and ATF4) and altered biomarkers in autophagy (LC3 and p62). CONCLUSIONS: Knee loading suppressed obesity-associated metabolic alterations and hepatic steatosis. These effects with knee loading might be associated with suppression of ER stress and promotion of autophagy. PMID- 29601136 TI - The advantage of calling things by the same name. PMID- 29601138 TI - Reaction Mechanism of Prephenate Dehydrogenase from the Alternative Tyrosine Biosynthesis Pathway in Plants. AB - Unlike metazoans, plants, bacteria, and fungi retain the enzymatic machinery necessary to synthesize the three aromatic amino acids l-phenylalanine, l tyrosine, and l-tryptophan de novo. In legumes, such as soybean, alfalfa, and common bean, prephenate dehydrogenase (PDH) catalyzes the tyrosine-insensitive biosynthesis of 4-hydroxyphenylpyruvate, a precursor to tyrosine. The three dimensional structure of soybean PDH1 was recently solved in complex with the NADP+ cofactor. This structure allowed for the identification of both the cofactor- and ligand-binding sites. Here, we present steady-state kinetic analysis of twenty site-directed active-site mutants of soybean (Glycine max) PDH compared to wild-type. Molecular docking of the substrate, prephenate, into the active site of the enzyme revealed its potential interactions with the active site residues and made a case for the importance of each residue in substrate recognition and/or catalysis, most likely through transition state stabilization. Overall, these results suggested that the active site of the enzyme is highly sensitive to any changes, as even subtle alterations substantially reduced the catalytic efficiency of the enzyme. PMID- 29601137 TI - Early disease progression in patients with localized natural killer/T-cell lymphoma treated with concurrent chemoradiotherapy. AB - Prognosis of patients with localized nasal extranodal natural killer/T-cell lymphoma, nasal type (ENKL) has been improved by non-anthracycline-containing treatments such as concurrent chemoradiotherapy (CCRT). However, some patients experience early disease progression. To clarify the clinical features and outcomes of these patients, data from 165 patients with localized nasal ENKL who were diagnosed between 2000 and 2013 at 31 institutes in Japan and who received radiotherapy with dexamethasone, etoposide, ifosfamide, and carboplatin (RT DeVIC) were retrospectively analyzed. Progression of disease within 2 years after diagnosis (POD24) was used as the definition of early progression. An independent dataset of 60 patients with localized nasal ENKL who received CCRT at Samsung Medical Center was used in the validation analysis. POD24 was documented in 23% of patients who received RT-DeVIC and in 25% of patients in the validation cohort. Overall survival (OS) from risk-defining events of the POD24 group was inferior to that of the reference group in both cohorts (P < .00001). In the RT DeVIC cohort, pretreatment elevated levels of serum soluble interleukin-2 receptor (sIL-2R), lactate dehydrogenase, C-reactive protein, and detectable Epstein-Barr virus DNA in peripheral blood were associated with POD24. In the validation cohort, no pretreatment clinical factor associated with POD24 was identified. Our study indicates that POD24 is a strong indicator of survival in localized ENKL, despite the different CCRT regimens adopted. In the treatment of localized nasal ENKL, POD24 is useful for identifying patients who have unmet medical needs. PMID- 29601139 TI - Myocardial fibrosis evaluated by diffusion-weighted imaging and its relationship to 3D contractile function in patients with hypertrophic cardiomyopathy. AB - BACKGROUND: Previous studies have shown that diffusion-weighted imaging (DWI) is sensitive to myocardial fibrosis in ischemic and nonischemic cardiomyopathy. PURPOSE: To explore the prognostic value of apparent diffusion coefficient (ADC) for detecting myocardial fibrosis and its relationship to the contractile function in hypertrophic cardiomyopathy (HCM). STUDY TYPE: Prospective. POPULATION: A total of 45 HCM patients and 20 controls. FIELD STRENGTH/SEQUENCE: 3.0T cardiac MRI. The cardiac MR sequences included cine, T1 mapping, and DWI. ASSESSMENT: According to the presence of late gadolinium enhancement (LGE) and the extracellular volume (ECV) values (+2 SD of control subjects), respectively, reader W and reader J assessed the value of ADC of each segment for detecting myocardial fibrosis and its relationship to impaired contractile function in HCM patients. STATISTICAL TESTS: Independent sample t-test, Pearson analysis, and intraclass correlation (ICC). RESULTS: The value of ECV was 23.6 +/- 3.0% for control. ECV >= 29.6% and ECV < 29.6% groups were classified. ADC values in the ECV >= 29.6% group were significantly increased compared to the ECV < 29.6% group, (2.41 +/- 0.23 MUm2 /ms vs. 2.03 +/- 0.16 MUm2 /ms, P < 0.005). Compared to the LGE - group, ECV (32.1 +/- 2.3% vs. 29.0 +/- 2.8%, P < 0.005) and ADC (2.60 +/- 0.18 MUm2 /ms vs. 2.10 +/- 0.07 MUm2 /ms, P < 0.005) values were significantly increased in the LGE + group. ADC values were linearly associated with ECV values (R2 = 0.65) in HCM patients. ADC values were linearly associated with circumferential and longitudinal strain (R2 = 0.60, R2 = 0.46), as well as circumferential, longitudinal, and radial strain rate (R2 = 0.13, R2 = 0.25, R2 = 0.17, respectively). DATA CONCLUSION: Contractile dysfunction in HCM is predominantly associated with ADC, which is a feasible alternative to ECV and LGE for detecting myocardial fibrosis.

AB - It is known that that human serum albumin (HSA) and alpha-lactalbumin (LA) possess DNA-binding sites. Electrophoretically homogeneous HSA and LA containing no canonical enzymes were isolated from human sera and milk. Here we have analyzed for the first time the possibility of DNA hydrolysis by these proteins. It was shown that HSA possesses metal-dependent DNase activity, while LA cannot hydrolyze DNA. Several rigid criteria have been applied to show that DNase activity is an intrinsic property of HSA from human sera and milk. HSA preparations were inactive after their dialysis against EDTA or in the presence of EDTA, but were activated after addition of several external metal ions: Mn2+ > Mg2+ > Ca2+ . The best activation of HSA preparations was observed in the presence of two metal ions: Mg2+ +Ca2+ > Mn2+ + Ca2+ >= Mn2+ + Mg2+ . In contrast to DNases having only one pH optimum, HSA preparations demonstrated two well-pronounced optima at pH 5.7-5.9 and 6.9-7.1 as well as a weak optimum at pH 8.4-8.6. These results demonstrate the diversity of HSA in the DNA hydrolysis at various pHs and in activation by various metal cofactors. Possible reasons for the diversity of HSA preparations are discussed.

AB - AIM: The recurrence rates of pruritus after stopping nalfurafine hydrochloride are unknown in chronic liver disease. METHODS: A prospective confirmatory trial was carried out to determine the recurrence rates of pruritus after cessation of nalfurafine hydrochloride in chronic liver disease. After pretreatment with nalfurafine hydrochloride for 4 weeks or more, 15 consecutive Japanese patients, who confirmed the improvement of pruritus (decrease in the visual analogue scale (VAS) of >=50 mm), were enrolled in the present study. Patients were classified to the continuous group (continuation of nalfurafine hydrochloride for 4 weeks) or the discontinuous group (cessation of nalfurafine hydrochloride) at the time of consent to study protocol, by self-determination. RESULTS: The recurrence rates (increase in VAS of >=25 mm after stopping nalfurafine hydrochloride) were 100% (5 of 5 patients) and 0% (0 of 10) in the discontinuous and continuous groups, respectively. In the discontinuous group, 3 patients selected retreatment with nalfurafine hydrochloride as salvage therapy, and they generally recovered to the levels of VAS at the discontinuation of treatment. CONCLUSION: The present prospective trial showed the high recurrence rates of pruritus after the stop of nalfurafine hydrochloride in chronic liver disease.

AB - The activity of CA1 neurons in the rodent hippocampus represents multiple aspects of learning episodes, including cue and place information. Previous reports on cue and place representation in CA1 have examined activity in single neurons and population recordings during free exploration of an environment or when actions are directed to either cue or place aspects of memory tasks. To better understand cue and place memory representation in CA1, and how these interact during goal directed navigation, we investigated population activity in CA1 during memory encoding and retrieval in a novel water task with two visibly distinct platforms, using mRNA for immediate early genes Arc and Homer1a as markers of neural activity. After training, relocating cues to new places induces an extensive, perhaps global, remapping of the memory code that is accompanied by altered navigation and rapid learning of new cue-place information. In addition, we have found a significant relationship between the extent of reactivation and overall cue choice accuracy. These findings demonstrate an important relationship between population remapping in CA1 and memory-guided behavior. PMID- 29601144 TI - oneED: Embedding a mindfulness-based wellness programme into an emergency department. AB - OBJECTIVE: ED staff are subject to many stressors, but there are few descriptions of collective approaches to enhancing wellness in this setting. We aim to describe a programme developed to address these issues at department level, to report the feasibility and sustainability of the programme, and its impact on staff. METHODS: The oneED programme was developed and delivered in a tertiary ED. The programme included a 1 day mindfulness workshop, followed by ongoing mindfulness activities embedded in clinical areas over the subsequent 12 months. A mixed-methods evaluation of the programme was conducted, which included quantitative validated psychological tools to measure anxiety, depression and emotional exhaustion, and pragmatic evaluation using surveys of participants and iterative appreciative inquiry. RESULTS: Eighty staff members attended the mindfulness workshop; 66 from ED. Following the workshop, understanding and frequency of mindfulness practice increased significantly in 47% of participants. Free-text survey results demonstrated that staff found the programme to be acceptable (80% survey participants) and of perceived value to themselves (50%) and the ED (60%). Appreciative inquiry led to modification of the programme: the 4 min pause is now conducted weekly rather than daily, the pause consists of a variety of activities, and group activities are made more overtly optional. CONCLUSION: A departmental wellness programme embedding mindfulness practice is feasible and sustainable. Potential for success is enhanced by an approach that is open to modification according to each institution's culture. PMID- 29601143 TI - Synthetic alpha-mangostin dilaurate strongly suppresses wide-spectrum organ metastasis in a mouse model of mammary cancer. AB - We previously reported that, in a mouse model of mammary cancer, alpha-mangostin alone exhibits anti-metastatic properties. To enhance this anti-metastatic effect, we examined the efficacy of synthetic alpha-mangostin dilaurate (MGD), prepared by adding lauric acid to alpha-mangostin, in the same experimental system wherein mice bearing mammary tumors are exposed to dietary MGD at 0, 2000 and 4000 ppm. Lauric acid has a high propensity for lymphatic absorption, which is the most common pathway of initial dissemination of many solid malignancies. Both mammary tumor volumes and wide-spectrum organ metastasis were markedly reduced at 2000 and 4000 ppm: furthermore, survival in the 4000-ppm group was significantly greater than in control mice. Apoptosis in mammary carcinomas was also significantly increased in the 4000-ppm group, whereas blood microvessel density and lymphatic vessel invasion were markedly reduced. In real-time PCR analyses of tumor samples, increased p21 and decreased Pcna expression were observed with 4000 ppm but values were not statistically significant when compared to expression in control tumors. However, exposure to 4000 ppm significantly decreased expression of phospho-Akt (Ser473/Thr308) as compared to the control, indicating a role in the anti-tumorigenic effects of MGD. These findings suggest that MGD may be useful for adjuvant therapy and chemoprevention and that conjugated medium-chain fatty acids may enhance the efficacy of certain chemotherapeutic agents. PMID- 29601145 TI - Comparative efficacy and safety of low-intensity warfarin therapy in preventing unprovoked recurrent venous thromboembolism: A systematic review and meta analysis. AB - BACKGROUND: Although there exists potential risk of bleeding, extended 'lifelong' conventional-intensity [international normalized ratio (INR): 2.0-3.0] warfarin anticoagulation is recommended for unprovoked venous thromboembolism (VTE) patients because of risk of recurrent VTE. Whether long-term low-intensity (INR: 1.5-2.0) warfarin therapy reduced the risk of major bleeding without substantially lowered antithrombotic efficacy is not well understood. The aim of this study was to perform a systematic review and meta-analysis to evaluate the risk-benefits of low-intensity warfarin therapy. METHODS: We conducted a comprehensive search of electronic databases and included randomized control trials (RCTs) that reported efficacy (recurrent VTE) and safety (bleeding episodes) of low-intensity warfarin therapy compared with conventional-intensity warfarin or placebo from inception through Jun 2016. RESULTS: Four RCTs reporting high GRADE quality evidence were included. Although the relative risk of recurrent VTE with low-intensity therapy was significantly increased [2.96 (95% CI: 1.40 to 6.24), P < .004] compared to conventional-intensity warfarin, there was significant decrease of relative risk when compared with placebo [0.37 (95% CI: 0.24 to 0.56), P < .00001]. As per included publications, no significant major bleeding episodes were observed in low-intensity warfarin group. CONCLUSIONS: Although less effective than conventional-intensity warfarin therapy this meta-analysis indicates that long-term low-intensity warfarin therapy is highly effective for preventing recurrent VTE than placebo, along with reduced risks of major bleeding and minimizing potential complications. PMID- 29601147 TI - Supervised physical exercise improves clinical, anthropometric and biochemical parameters in adult cystic fibrosis patients: A 2-year evaluation. AB - OBJECTIVE: Cystic fibrosis (CF) is the most common inherited, life limiting condition among Caucasians. No healing therapy is currently available for patients with CF. The aim of the study was to define clinical, anthropometric and biochemical effects of regular, supervised physical exercise in a large cohort of patients with CF. MATERIALS AND METHODS: Fifty-nine adult patients with CF that performed regularly supervised physical exercise in the last 3 years in comparison to 59 sex and age matched sedentary patients with CF were included in the study. RESULTS: Physical exercise had significantly beneficial effects on: (a) FEV1% decline; (b) anthropometric parameters (lower number of cases with altered BMI, waist and arm circumferences); (c) lipid and glucose metabolism; (d) vitamin D serum levels. Of course, some of this improvement may be because of the better adherence to therapy typical of patients with CF that perform physical activity. CONCLUSIONS: Such clinical and metabolic effects make supervised physical activity one of the hubs in managing patients with CF.

AB - PURPOSE: This article aims to define the concept of maintenance of continuity in older adulthood (MCOA) and assist nurses to better understand the concept of MCOA. METHODS: The method by Walker and Avant was used for this concept analysis. FINDINGS: In the literature, MCOA is defined as a psychosocial adaptation strategy by searching for preference and familiarity, making a sense of connection, and creating coherence. CONCLUSIONS: MCOA has potential to improve psychosocial adjustment to difficult life transitions as a coping mechanism. IMPLICATION FOR NURSING PRACTICE: Insights about MCOA in nursing may contribute to improved patient care outcomes by assisting nurses to understand the elderly's experience during age-related challenges from a life course perspective. PMID- 29601146 TI - Quantification of near-wall hemodynamic risk factors in large-scale cerebral arterial trees. AB - Detailed hemodynamic analysis of blood flow in pathological segments close to aneurysm and stenosis has provided physicians with invaluable information about the local flow patterns leading to vascular disease. However, these diseases have both local and global effects on the circulation of the blood within the cerebral tree. The aim of this paper is to demonstrate the importance of extending subject specific hemodynamic simulations to the entire cerebral arterial tree with hundreds of bifurcations and vessels, as well as evaluate hemodynamic risk factors and waveform shape characteristics throughout the cerebral arterial trees. Angioarchitecture and in vivo blood flow measurement were acquired from healthy subjects and in cases with symptomatic intracranial aneurysm and stenosis. A global map of cerebral arterial blood flow distribution revealed regions of low to high hemodynamic risk that may significantly contribute to the development of intracranial aneurysms or atherosclerosis. Comparison of pre intervention and post-intervention of pathological cases further shows large angular phase shift (~33.8 degrees ), and an augmentation of the peak-diastolic velocity. Hemodynamic indexes of waveform analysis revealed on average a 16.35% reduction in the pulsatility index after treatment from lesion site to downstream distal vessels. The lesion regions not only affect blood flow streamlines of the proximal sites but also generate pulse wave shift and disturbed flow in downstream vessels. This network effect necessitates the use of large-scale simulation to visualize both local and global effects of pathological lesions.

FIELD STRENGTH/SEQUENCE: QSI was performed with a 3T MRI system using a diffusion weighted echo-planar imaging sequence: repetition time, 10,000 msec; echo time, 216 or 210 msec; field of view, 113 * 73.45 mm; matrix, 120 * 78; section thickness, 4 mm; and 11 b values ranging from 0 to 9000 s/mm2 . ASSESSMENT: The mean displacement (MDP; MUm), zero-displacement probability (ZDP; arbitrary unit [a.u.]), kurtosis (K; a.u.), and apparent diffusion coefficient (ADC) were analyzed by two observers and compared with histopathologic findings. STATISTICAL TESTS: Spearman's rank correlation coefficient, Mann-Whitney U-test, and ROC curve analyses. RESULTS: For all 20 carcinomas, the MDP, ZDP, K, and ADC were 8.87 +/- 0.37 MUm, 82.0 +/- 6.2 a.u., 74.3 +/- 3.0 a.u., and 0.219 +/- 0.040 * 10 3 mm2 /s, respectively. The MDP (r = -0.768; P < 0.001), ZDP (r = 0.768; P < 0.001), and K (r = 0.785; P < 0.001) were significantly correlated with the HG of CRC, but not the ADC (r = 0.088; P = 0.712). There were also significant differences in the MDP, ZDP, and K between metastatic and nonmetastatic LNs (all, P < 0.001), but not the ADC (P = 0.082). In the HG of CRC and LNM, the area under the curve was significantly greater for MDP, ZDP, and K than for ADC. DATA CONCLUSION: QSI provides useful diagnostic information to assess the HG and extent of LNM in CRC. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;48:1059-1068. PMID- 29601151 TI - Combined DFT and Differential Electrochemical Mass Spectrometry Investigation of the Effect of Dopants in Secondary Zinc-Air Batteries. AB - Zinc-air batteries offer the potential of low-cost energy storage with high specific energy, but at present secondary Zn-air batteries suffer from poor cyclability. To develop economically viable secondary Zn-air batteries, several properties need to be improved: choking of the cathode, catalyzing the oxygen evolution and reduction reactions, limiting dendrite formation and suppressing the hydrogen evolution reaction (HER). Understanding and alleviating HER at the negative electrode in a secondary Zn-air battery is a substantial challenge, for which it is necessary to combine computational and experimental research. Here, we combine differential electrochemical mass spectrometry (DEMS) and density functional theory (DFT) calculations to investigate the fundamental role and stability when cycling in the presence of selected beneficial additives, that is, In and Bi, and Ag as a potentially unfavorable additive. We show that both In and Bi have the desired property for a secondary battery, that is, upon recharging they will remain on the surface, thereby retaining the beneficial effects on Zn dissolution and suppression of HER. This is confirmed by DEMS, where it is observed that In reduces HER and Bi affects the discharge potential beneficially compared to a battery without additives. Using a simple procedure based on adsorption energies calculated with DFT, it is found that Ag suppresses OH adsorption, but, unlike In and Bi, it does not hinder HER. Finally, it is shown that mixing In and Bi is beneficial compared to the additives by themselves as it improves the electrochemical performance and cyclic stability of the secondary Zn air battery.

AB - BACKGROUND: Spacers are inserted into the middle meatal space (MMS) following functional endoscopic sinus surgery (FESS) to prevent lateralization of the middle turbinate, scarring, and synechiae. Our objective was to determine if the incidence of postoperative synechiae, facial pain/discomfort, pain during spacer removal, scarring, and discharge differed between nasal cavities receiving Silastic or gloved-Merocel (GM) spacers following FESS. METHODS: A double-blind, randomized controlled trial (RCT) was conducted in adults requiring bilateral FESS for chronic rhinosinusitis (CRS) +/- nasal polyposis. Participants served as their own controls, with each subject receiving both a Silastic and GM spacer. Spacers were inserted into the MMS during FESS and left in situ for 6 days. Participants were reviewed at 6 days, 5 weeks, and 12 weeks postoperatively. The presence of synechiae and scarring were evaluated endoscopically. Inflammation, discharge, and pain during spacer removal were assessed using a visual analogue scale (VAS). RESULTS: Forty-eight participants (96 nasal cavities) were recruited. Preoperatively, Lund-Mackay computed tomography (CT) scores were similar between Silastic-treated and GM-treated cavities (6.38 +/- 2.35 vs 6.18 +/- 2.17). The incidence of synechiae and scarring did not differ significantly between spacers up to 12 weeks postoperatively. Pain during spacer removal was significantly greater for Silastic than GM spacers (2.13 +/- 1.34 vs 1.51 +/- 1.23, p = 0.020). Facial pain prior to removal and extent of discharge did not differ significantly between spacers. CONCLUSION: Following FESS, patients report less pain during removal of GM than Silastic spacers. However, the likelihood of synechiae and scarring did not differ between either of the spacers. PMID- 29601152 TI - Combat zone exposure and respiratory tract disease. AB - BACKGROUND: The impact of deployment to combat zones on the respiratory and sinonasal health of U.S. soldiers is an emerging public health concern. Retrospective studies have shown a correlation between deployment and development of post-deployment pathology, particularly of the aerodigestive system. Respiratory disease, including sinusitis, allergic rhinitis, and asthma, are commonly reported in soldiers deployed to the Middle East and Southwest Asia. METHODS: Current literature pertaining to combat zone exposure and development of respiratory disease was retrieved using PubMed, Embase, Web of Science, and Google Scholar. RESULTS: Several types of combat zone exposures exist that may play an influential role in the development of upper and lower respiratory tract diseases. Exposures including foreign dusts, harsh environments, particulate size, and close living quarters may play a causative role. The effect of combat zone exposures has been better examined for lower respiratory tract diseases; however, with the theory of the unified airway, the upper respiratory tract may also be involved. There is evidence that the upper respiratory tract is susceptible, with an increased risk for development of sinusitis and sinonasal disease; however, the quality of evidence of the present literature is generally low. CONCLUSION: More research is necessary to determine a pathophysiologic mechanism between combat zone exposure and the development of sinonasal disease. Practicing otolaryngologists should be aware of the possibility of combat zone exposures that could contribute to rhinologic symptomatology. PMID- 29601153 TI - Lacrimal sac exposure and a superior lateral anterior pedicle flap to improve outcomes of Draf type II and III procedures. AB - BACKGROUND: Although the efficacy of Draf type II and III procedures for frontal sinus diseases is well recognized, a certain amount of postoperative stenosis of the frontal neo-ostium occurs. Exposed bone induces inflammation and leads to osteoneogenesis. To prevent stenosis, we developed a surgical technique designed to minimize bone exposure while maximizing the frontal neo-ostium area created with Draf type II and III procedures. We fully exposed the lacrimal sac and used a superior lateral anterior pedicle flap to cover the exposed bone during the Draf procedure. We aimed to describe our technique. METHODS: We reviewed 19 patients who underwent a Draf type II or III procedure with our technique. Endoscopic views from the follow-ups and complications were evaluated. RESULTS: Overall, the neo-ostium remained patent in all patients. No complications, such as synechiae or orbital injury, were seen in any of the patients. CONCLUSION: Draf type II and III procedures with lacrimal sac exposure and a superior lateral anterior pedicle flap are convenient and seem to be effective. However, further studies with larger numbers of patients are needed to verify our technique. PMID- 29601154 TI - Intentional Inconsistency as Gender-Neutral Language Evolves.

PMID- 29601173 TI - Langmuir-Blodgett Thin Films of Diketopyrrolopyrrole-Based Amphiphiles. AB - We report on two pi-conjugated donor-acceptor-donor (D-A-D) molecules of amphiphilic nature, aiming to promote intermolecular ordering and carrier mobility in organic electronic devices. Diketopyrrolopyrrole was selected as the acceptor moiety that was disubstituted with nonpolar and polar functional groups, thereby providing the amphiphilic structures. This structural design resulted in materials with a strong intermolecular order in the solid state, which was confirmed by differential scanning calorimetry and polarized optical microscopy. Langmuir-Blodgett (LB) films of ordered mono- and multilayers were transferred onto glass and silicon substrates, with layer quality, coverage, and intermolecular order controlled by layer compression pressure on the LB trough. Organic field-effect transistors and organic photovoltaics devices with active layers consisting of the amphiphilic conjugated D-A-D-type molecules were constructed to demonstrate that the LB technique is an effective layer-by-layer deposition approach to fabricate self-assembled, ordered thin films.

PMID- 29601175 TI - Interfacial Energy-Level Alignment for High-Performance All-Inorganic Perovskite CsPbBr3 Quantum Dot-Based Inverted Light-Emitting Diodes. AB - All-inorganic perovskite light-emitting diode (PeLED) has a high stability in ambient atmosphere, but it is a big challenge to achieve high performance of the device. Basically, device design, control of energy-level alignment, and reducing the energy barrier between adjacent layers in the architecture of PeLED are important factors to achieve high efficiency. In this study, we report a CsPbBr3 based PeLED with an inverted architecture using lithium-doped TiO2 nanoparticles as the electron transport layer (ETL). The optimal lithium doping balances the charge carrier injection between the hole transport layer and ETL, leading to superior device performance. The device exhibits a current efficiency of 3 cd A 1, a luminance efficiency of 2210 cd m-2, and a low turn-on voltage of 2.3 V. The turn-on voltage is one of the lowest values among reported CsPbBr3-based PeLEDs. A 7-fold increase in device efficiencies has been obtained for lithium-doped TiO2 compared to that for undoped TiO2-based devices. PMID- 29601176 TI - Potent 1,2,4-Triazino[5,6 b]indole-3-thioether Inhibitors of the Kanamycin Resistance Enzyme Eis from Mycobacterium tuberculosis. AB - A common cause of resistance to kanamycin (KAN) in tuberculosis is overexpression of the enhanced intracellular survival (Eis) protein. Eis is an acetyltransferase that multiacetylates KAN and other aminoglycosides, rendering them unable to bind the bacterial ribosome. By high-throughput screening, a series of substituted 1,2,4-triazino[5,6 b]indole-3-thioether molecules were identified as effective Eis inhibitors. Herein, we purchased 17 and synthesized 22 new compounds, evaluated their potency, and characterized their steady-state kinetics. Four inhibitors were found not only to inhibit Eis in vitro, but also to act as adjuvants of KAN and partially restore KAN sensitivity in a Mycobacterium tuberculosis KAN-resistant strain in which Eis is upregulated. A crystal structure of Eis in complex with a potent inhibitor and CoA shows that the inhibitors bind in the aminoglycoside binding site snugly inserted into a hydrophobic cavity. These inhibitors will undergo preclinical development as novel KAN adjuvant therapies to treat KAN-resistant tuberculosis. PMID- 29601177 TI - Pulsed Hydrogen-Deuterium Exchange Illuminates the Aggregation Kinetics of alpha Synuclein, the Causative Agent for Parkinson's Disease. AB - alpha-Synuclein (aS) forms toxic intermediates ranging from small oligomers and protofibrils to large amyloid fibrils. Understanding the time course of aS fibril formation and the role played by its regions is critical for therapeutic intervention. Here, we used pulsed hydrogen-deuterium exchange and mass spectrometry (HDX-MS) for the first time to probe kinetic intermediates of the full aS aggregation in vitro, achieving kinetic snapshots containing spatially resolved protein information about critical stages. Monitoring the resultant mass shifts shows distinct binomial abundances for two main exchange profiles: one that represents a fast-exchanging, solvent-accessible species and another with a more protected nature. We show using a series of proteolytic peptides from the full protein that self-association is most pronounced in the non-amyloid-beta component region and less so for either terminus. The N-terminus, however, shows a minor protected population at mid- and late times, whereas the C-terminus shows predominantly unimodal HDX, indicating that these regions are devoid of any large conformational rearrangements. Focusing on the hydrophobic core, we confirmed and modeled the different isotopic distributions and calculated their relative fractions to discern their individual contributions. The data fitting reports respective t1/2 values, which are nearly identical and do not depend on location. We followed the aggregation by complementary transmission electron microscopy to observe the morphology of aggregates and circular dichroism to assess changes in secondary structure. Our results provide a detailed picture of aS aggregation in vitro and demonstrate that HDX-MS offers unique spatially resolved, coexisting kinetic intermediates in solution. This new platform is suitable for testing promising inhibitors of aS aggregation. PMID- 29601178 TI - Enhanced Osteogenic Differentiation of Stem Cells on Phase-Engineered Graphene Oxide. AB - Graphene oxide (GO) has attracted significant interest as a template material for multiple applications due to its two-dimensional nature and established functionalization chemistries. However, for applications toward stem cell culture and differentiation, GO is often reduced to form reduced graphene oxide, resulting in a loss of oxygen content. Here, we induce a phase transformation in GO and demonstrate its benefits for enhanced stem cell culture and differentiation while conserving the oxygen content. The transformation results in the clustering of oxygen atoms on the GO surface, which greatly improves its ability toward substance adherence and results in enhanced differentiation of human mesenchymal stem cells toward the osteogenic lineage. Moreover, the conjugating ability of modified GO strengthened, which was examined by auxiliary osteogenic growth peptide conjugation. Overall, our work demonstrates GO's potential for stem cell applications while maintaining its oxygen content, which could enable further functionalization and fabrication of novel nano biointerfaces. PMID- 29601179 TI - Enhancing Electrochemical Performance of Graphene Fiber-Based Supercapacitors by Plasma Treatment. AB - Graphene fiber-based supercapacitors (GFSCs) hold high power density, fast charge discharge rate, ultralong cycling life, exceptional mechanical/electrical properties, and safe operation conditions, making them very promising to power small wearable electronics. However, the electrochemical performance is still limited by the severe stacking of graphene sheets, hydrophobicity of graphene fibers, and complex preparation process. In this work, we develop a facile but robust strategy to easily enhance electrochemical properties of all-solid-state GFSCs by simple plasma treatment. We find that 1 min plasma treatment under an ambient condition results in 33.1% enhancement of areal specific capacitance (36.25 mF/cm2) in comparison to the as-prepared GFSC. The energy density reaches 0.80 MUW h/cm2 in polyvinyl alcohol/H2SO4 gel electrolyte and 18.12 MUW h/cm2 in poly(vinylidene difluoride)/ethyl-3-methylimidazolium tetrafluoroborate electrolyte, which are 22 times of that of as-prepared ones. The plasma-treated GFSCs also exhibit ultrahigh rate capability (69.13% for 40 s plasma-treated ones) and superior cycle stability (96.14% capacitance retention after 20 000 cycles for 1 min plasma-treated ones). This plasma strategy can be extended to mass-manufacture high-performance carbonaceous fiber-based supercapacitors, such as graphene and carbon nanotube-based ones. PMID- 29601180 TI - Filament Growth and Resistive Switching in Hafnium Oxide Memristive Devices. AB - We report on the resistive switching in TiN/Ti/HfO2/TiN memristive devices. A resistive switching model for the device is proposed, taking into account important experimental and theoretical findings. The proposed switching model is validated using 2D and 3D kinetic Monte Carlo simulation models. The models are consistently coupled to the electric field and different current transport mechanisms such as direct tunneling, trap-assisted tunneling, ohmic transport, and transport through a quantum point contact have been considered. We find that the numerical results are in excellent agreement with experimentally obtained data. Important device parameters, which are difficult or impossible to measure in experiments, are calculated. This includes the shape of the conductive filament, width of filament constriction, current density, and temperature distribution. To obtain insights in the operation of the device, consecutive cycles have been simulated. Furthermore, the switching kinetics for the forming and set process for different applied voltages is investigated. Finally, the influence of an annealing process on the filament growth, especially on the filament growth direction, is discussed.

AB - This study presents innovative Ti1- xNb xN-Ag films obtained by a suitable combination of low-energy and high-energy sputtering leading to bacterial inactivation. The bacterial inactivation kinetics by the TiNbN layers was drastically enhanced by the addition of 6-7% Ag and proceeded to completion within 3 h after the film autoclaving. By X-ray photoelectron spectroscopy (XPS), the samples after autoclaving presented in their upper layers TiO2, Nb2O5 and Ag2O with a surface composition of Ti0.81Nb0.19N0.99Ag0.068. Surface potential/pH changes in the Ti1- xNb xN-Ag films were monitored during bacterial inactivation. Surface redox processes during the bacterial inactivation were detected by XPS. The diffusion of Ag in the Ti1- xNb xN-Ag films was followed at 50 and 70 degrees C pointing. The beneficial thermal treatment points out to the bifunctional bacterial inactivation properties of these films and their potential application in healthcare facilities. Interfacial charge transfer (IFCT) under light irradiation between Ag2O, Nb2O5 and TiO2 is suggested consistent with the data found during the course of this study. The TiO2/Nb2O5 lattice mechanism is discussed in the framework of the Verwey's controlled valence model. The surface properties of the Ti1- xNb xN-Ag films were investigated by X-ray diffraction, atomic force microscopy, and scanning electron microscopy. PMID- 29601182 TI - Sniffing Entrapped Humans with Sensor Arrays. AB - Earthquakes are lethal natural disasters frequently burying people alive under collapsed buildings. Tracking entrapped humans from their unique volatile chemical signature with hand-held devices would accelerate urban search and rescue (USaR) efforts. Here, a pilot study is presented with compact and orthogonal sensor arrays to detect the breath- and skin-emitted metabolic tracers acetone, ammonia, isoprene, CO2, and relative humidity (RH), all together serving as sign of life. It consists of three nanostructured metal-oxide sensors (Si doped WO3, Si-doped MoO3, and Ti-doped ZnO), each specifically tailored at the nanoscale for highly sensitive and selective tracer detection along with commercial CO2 and humidity sensors. When tested on humans enclosed in plethysmography chambers to simulate entrapment, this sensor array rapidly detected sub-ppm acetone, ammonia, and isoprene concentrations with high accuracies (19, 21, and 3 ppb, respectively) and precision, unprecedented by portable sensors but required for USaR. These results were in good agreement (Pearson's correlation coefficients >=0.9) with benchtop selective reagent ionization time-of-flight mass spectrometry (SRI-TOF-MS). As a result, an inexpensive sensor array is presented that can be integrated readily into hand held or even drone-carried detectors for first responders to rapidly screen affected terrain. PMID- 29601183 TI - Specifically and Visually Detect Methyl-Mercury and Ethyl-Mercury in Fish Sample Based on DNA-Templated Alloy Ag-Au Nanoparticles. AB - Methyl-mercury (CH3Hg+) and ethyl-mercury (C2H5Hg+) have much higher toxicity than Hg2+ and can be more easily accumulated by organisms to form severe bioamplification. Hence, the specific and on-site detection of CH3Hg+ and C2H5Hg+ in seafood is of great significance and a hard challenge. We herein designed two T-rich aptamers (HT5 and HT7) for specifically recognizing CH3Hg+ and the total of CH3Hg+ and C2H5Hg+, respectively. In the presence of all Au3+, Ag+, and T-rich aptamer, CH3Hg+ and C2H5Hg+ specifically and preferentially bind with aptamer and thus induced the formation of alloy Ag-Au nanoparticles after reduction, which led to the color change in solution. This provided a sensing platform for the instrument-free visual discrimination and detection of CH3Hg+ and C2H5Hg+. By using HT5 as probe, the method can be used to detect as low as 5.0 MUM (equivalent to 1.0 MUg Hg/g) of CH3Hg+ by bare eye observation and 0.5 MUM (equivalent to 100 ng Hg/g) of CH3Hg+ by UV-visible spectrometry. By using HT7 as probe, the method can be used to detect the total concentration of CH3Hg+ and C2H5Hg+ with a visual detection limit of 5.0 MUM (equivalent to 1.0 MUg Hg/g) and a UV-visible spectrometry detection limit of 0.6 MUM (equivalent to 120 ng Hg/g). The proposed method has been successfully used to detect CH3Hg+ and C2H5Hg+ in fish muscle samples with a recovery of 101-109% and a RSD ( n = 6) < 8%. The success of this study provided a potential method for the specific and on-site detection of CH3Hg+ and C2H5Hg+ in seafood by only bare eye observation. PMID- 29601184 TI - Exploring Conditions for Ultrafine Particle Formation from Oxidation of Cigarette Smoke in Indoor Environments. AB - Cigarette smoke is an important source of particles and gases in the indoor environment. In this work, aging of side-stream cigarette smoke was studied in an environmental chamber via exposure to ozone (O3), hydroxyl radicals (OH) and indoor fluorescent lights. Aerosol mass concentrations increased by 13-18% upon exposure to 15 ppb O3 and by 8-42% upon exposure to 0.45 ppt OH. Ultrafine particle (UFP) formation was observed during all ozone experiments, regardless of the primary smoke aerosol concentration (185-1950 MUg m-3). During OH oxidation, however, UFP formed only when the primary particle concentration was relatively low (<130 MUg m-3) and the OH concentration was high (~1.1 * 107 molecules cm-3). Online aerosol composition measurements show that oxygen- and nitrogen- containing species were formed during oxidation. Gas phase oxidation of NO to NO2 occurred during fluorescent light exposure, but neither primary particle growth nor UFP formation were observed. Overall, exposure of cigarette smoke to ozone will likely lead to UFP formation in indoor environments. On the other hand, UPF formation via OH oxidation will only occur when OH concentrations are high (~107 molecules cm-3), and is therefore less likely to have an impact on indoor aerosol associated with cigarette smoke. PMID- 29601185 TI - Lead Diversification at the Nanomole Scale Using Liver Microsomes and Quantitative Nuclear Magnetic Resonance Spectroscopy: Application to Phosphodiesterase 2 Inhibitors. AB - In this report, we describe a method whereby lead molecules can be converted into several new analogues each using liver microsomes. Less than one micromole of substrate is incubated with liver microsomes (mouse, rat, hamster, guinea pig, rabbit, dog, monkey, or human) to produce multiple products which are isolated and analyzed by quantitative cryomicroprobe NMR (qNMR) spectroscopy. The solutions from qNMR analysis were then used as stocks that were diluted into biochemical assays. Nine human phosphodiesterase-2 (PDE2) inhibitors yielded 36 new analogues. Products were tested for PDE2 inhibition, intrinsic clearance in human hepatocytes, and membrane permeability. Two of the products (2c and 4b) were 3-10* more potent than their respective parent compounds and also had improved metabolic stability. Others offered insights into structure-activity relationships. Overall, this process of using liver microsomes at a submicromole scale of substrate is a useful approach to rapid and cost-effective late-stage lead diversification. PMID- 29601186 TI - Periodic Density Functional Theory Study of the Structure, Raman Spectrum, and Mechanical Properties of Schoepite Mineral. AB - The structure and Raman spectrum of schoepite mineral, [(UO2)8O2(OH)12].12H2O, was studied by means of theoretical calculations. The computations were carried out by using density functional theory with plane waves and pseudopotentials. A norm-conserving pseudopotential specific for the U atom developed in a previous work was employed. Because it was not possible to locate H atoms directly from X ray diffraction (XRD) data by structure refinement in previous experimental studies, all of the positions of the H atoms in the full unit cell were determined theoretically. The structural results, including the lattice parameters, bond lengths, bond angles, and powder XRD pattern, were found to be in good agreement with their experimental counterparts. However, the calculations performed using the unit cell designed by Ostanin and Zeller in 2007, involving half of the atoms of the full unit cell, led to significant errors in the computed powder XRD pattern. Furthermore, Ostanin and Zeller's unit cell contains hydronium ions, H3O+, which are incompatible with the experimental information. Therefore, while the use of this schoepite model may be a very useful approximation requiring a much smaller amount of computational effort, the full unit cell should be used to study this mineral accurately. The Raman spectrum was also computed by means of density functional perturbation theory and compared with the experimental spectrum. The results were also in agreement with the experimental data. A normal-mode analysis of the theoretical spectra was performed to assign the main bands of the Raman spectrum. This assignment significantly improved the current empirical assignment of the bands of the Raman spectrum of schoepite mineral. In addition, the equation of state and elastic properties of this mineral were determined. The crystal structure of schoepite was found to be stable mechanically and dynamically. Schoepite can be described as a brittle material exhibiting small anisotropy and large compressibility in the direction perpendicular to the layers, which characterize its structure. The calculated bulk modulus, B, was ~35 GPa. PMID- 29601188 TI - Exploiting Ancillary Ligation To Enable Nickel-Catalyzed C-O Cross-Couplings of Aryl Electrophiles with Aliphatic Alcohols. AB - The use of (L)Ni( o-tolyl)Cl precatalysts (L = PAd-DalPhos or CyPAd-DalPhos) enables the C( sp2)-O cross-coupling of primary, secondary, or tertiary aliphatic alcohols with (hetero)aryl electrophiles, including unprecedented examples of such nickel-catalyzed transformations employing (hetero)aryl chlorides, sulfonates, and pivalates. In addition to offering a competitive alternative to palladium catalysis, this work establishes the feasibility of utilizing ancillary ligation as a complementary means of promoting challenging nickel-catalyzed C( sp2)-O cross-couplings, without recourse to precious-metal photoredox catalytic methods. PMID- 29601187 TI - Characterization of Tetrahydrolipstatin and Stereoderivatives on the Inhibition of Essential Mycobacterium tuberculosis Lipid Esterases. AB - Tetrahydrolipstatin (THL) is a covalent inhibitor of many serine esterases. In mycobacteria, THL has been found to covalently react with 261 lipid esterases upon treatment of Mycobacterium bovis cell lysate. However, the covalent adduct is considered unstable in some cases because of the hydrolysis of the enzyme linked THL adduct resulting in catalytic turnover. In this study, a library of THL stereoderivatives was tested against three essential Mycobacterium tuberculosis lipid esterases of interest for drug development to assess how the stereochemistry of THL affects respective enzyme inhibition and allows for cross enzyme inhibition. The mycolyltransferase Antigen 85C (Ag85C) was found to be stereospecific with regard to THL; covalent inhibition occurs within minutes and was previously shown to be irreversible. Conversely, the Rv3802 phospholipase A/thioesterase was more accepting of a variety of THL configurations and uses these compounds as alternative substrates. The reaction of the THL stereoderivatives with the thioesterase domain of polyketide synthase 13 (Pks13 TE) also leads to hydrolytic turnover and is nonstereospecific but occurs on a slower, multihour time scale. Our findings suggest the stereochemistry of the beta-lactone ring of THL is important for cross enzyme reactivity, while the two stereocenters of the peptidyl arm can affect enzyme specificity and the catalytic hydrolysis of the beta-lactone ring. The observed kinetic data for all three target enzymes are supported by recently published X-ray crystal structures of Ag85C, Rv3802, and Pks13-TE. Insights from this study provide a molecular basis for the kinetic modulation of three essential M. tuberculosis lipid esterases by THL and can be applied to increase potency and enzyme residence times and enhance the specificity of the THL scaffold. PMID- 29601189 TI - The True Catalyst Revealed: The Intervention of Chiral Ca and Mg Phosphates in Bronsted Acid Promoted Asymmetric Mannich Reactions. AB - The acetylacetone-benzaldimine Mannich reaction catalyzed by Mg(II) and Ca(II) salts of chiral phosphoric acids (CPA) has been investigated computationally by QM/MM methods. Enantioselectivity in this reaction is both larger than and in the opposite sense to that observed for the same reaction catalyzed by the protic CPA catalyst alone. We present a mechanistic model from which the characteristic differences between these metal and metal-free catalysts, which can coexist in the same reaction mixture, can be understood. Alkaline earth salts with chiral phosphate counterions are found to be more catalytically active than the protic form, and the Ca(II) and Mg(II) CPA salts react via different mechanisms, with a higher coordination number favored by calcium over magnesium. In the well-ordered chiral cavities around these metal centers, asymmetric induction arises from the steric interaction with the imine protecting group in the unfavorable pathway, with both substrates adopting well-defined conformations. These mechanistic models have allowed us to rationalize the stereochemical outcome across a range of bimolecular reactions promoted by divalent metal phosphates formed with different CPAs.

AB - The Mukaiyama aldol reaction has been used to efficiently install a lateral chain at the C-9 position of the Wieland-Miescher ketone derivative 3 within two steps, representing a shortcut compared to that of the classical sequences. The treatment of the silylated enol ether 8 with a wide range of acetals in the presence of tin tetrachloride led to a the diastereoselective construction of the C-9 quaternary center of 33 new building blocks derived from the Wieland-Miescher ketone derivative 3. PMID- 29601191 TI - Selective Gene Delivery for Integrating Exogenous DNA into Plastid and Mitochondrial Genomes Using Peptide-DNA Complexes. AB - Selective gene delivery into organellar genomes (mitochondrial and plastid genomes) has been limited because of a lack of appropriate platform technology, even though these organelles are essential for metabolite and energy production. Techniques for selective organellar modification are needed to functionally improve organelles and produce transplastomic/transmitochondrial plants. However, no method for mitochondrial genome modification has yet been established for multicellular organisms including plants. Likewise, modification of plastid genomes has been limited to a few plant species and algae. In the present study, we developed ionic complexes of fusion peptides containing organellar targeting signal and plasmid DNA for selective delivery of exogenous DNA into the plastid and mitochondrial genomes of intact plants. This is the first report of exogenous DNA being integrated into the mitochondrial genomes of not only plants, but also multicellular organisms in general. This fusion peptide-mediated gene delivery system is a breakthrough platform for both plant organellar biotechnology and gene therapy for mitochondrial diseases in animals.

AB - The new selenide Cs2Ge3In6Se14, featuring its own structure type with germanium in mixed-valence states, is discovered via a solid-state reaction at 1173 K. The compound crystallizes in the R3 m space group with a = 7.9951(6) A and c = 41.726(4) A. Two adjacent condensed layers of InSe4 tetrahedra are linked by a [Ge2+Se6] octahedron into a double slice that is further stacked along the c direction with a packing sequence of ... abca... through the [Ge3+2Se6] dimer via its Ge-Ge metallic bond. The coexistence of Ge2+/Ge3+ and Ge-Ge metallic bonding has been confirmed by XPS and ELF analyses, respectively. More interestingly, although sharing many structure similarities, Cs2Ge3In6Se14 and our previously reported Cs2Ge3In6Te14 reveal a R3 m to P3 m1 structure transformation with a tripled c parameter. Single-crystal diffraction data and a thorough structure survey of related compounds point out that such a transformation is driven by the size preference of the [Ge2Q6] dimer. The title compound possesses a band gap of 2.08 eV and shows photodegradation of RhB under visible light that is more efficient than that for the commercial P25.

AB - The mechanism and selectivity of the asymmetric Friedel-Crafts (F-C) alkylation reaction between indole and chalcone catalyzed by chiral N, N'-dioxide-Sc(III) complexes were investigated at the M06/6-311+G(d,p)//M06/[LANL2DZ,6 31G(d)](SMD,CH2Cl2) level. The reaction occurred via a three-step mechanism: (i) the C3-Cbeta bond formation by interacting the most mucleophilic C3 center of indole with the most electrophilic Cbeta center of chalcone; (ii) the abstraction of the proton at the C3 atom of indole by counterion OTf-; (iii) proton transfer from HOTf to the Calpha atom of chalcone, generating the F-C alkylation product. The reaction preferred to occur along the favorable re-face attack pathway, producing the dominant R-product. The turnover frequency (TOF) of catalysis was predicted to be 1.59 * 10-7 s-1, with a rate constant of K( T) = 1.58 * 10-7 exp( 29057/ RT) dm6.mol-2.s-1 over the temperature range of 248-368 K. Activation strain model (ASM) and energy decomposition analysis (EDA), as well as noncovalent interaction (NCI) analysis, for the stereocontrolling transition state revealed that the substituent attached to the N atom of the amide subunits as well as the amino acid backbone of ligand played important roles in chiral inductivity. The benzyl group with structural flexibility tended to form strong pi-pi stacking with substrate as well as the terminal phenyl group of chalcone, stabilizing re-face attack transition state.

AB - N-Heterocyclic carbenes (NHCs) have become without doubt one of the most exciting and popular species in chemical science due to the ease of their preparation and modularity in stereoelectronic properties. Numerous types of NHCs have been prepared, and various experimental methodologies have been proposed for the study of their electronic properties in order to rationalize reactivities observed. The objective of this article is to provide a comprehensive overview of the most common and popular ones among them. In particular, these include the nickel(0) based TEP, its rhodium(I) and iridium(I) variants, LEP and related electrochemical methods, the palladium(II)-based HEP, phosphinidene- and selenourea-based methods, as well as the use of direct 1 J(C-H) coupling constants of the precarbene carbon in azolium salts. Each individual method and the underlying principle of detection it utilizes will be critically discussed in terms of strength and weakness. In addition, comprehensive amounts of data from various NHCs are compiled for the purpose of comparison. These are also meant to help the scientist in better understanding their own research data and possibly providing directions for their future research, which rely on the unique electronic properties of NHCs.

AB - Klebsazolicin (KLB) is a recently discovered Klebsiella pneumonia peptide antibiotic targeting the exit tunnel of bacterial ribosome. KLB contains an N terminal amidine ring and four azole heterocycles installed into a ribosomally synthesized precursor by dedicated maturation machinery. Using an in vitro system for KLB production, we show that the YcaO-domain KlpD maturation enzyme is a bifunctional cyclodehydratase required for the formation of both the core heterocycles and the N-terminal amidine ring. We further demonstrate that the amidine ring is formed concomitantly with proteolytic cleavage of azole containing pro-KLB by a cellular protease TldD/E. Members of the YcaO family are diverse enzymes known to activate peptide carbonyls during natural product biosynthesis leading to the formation of azoline, macroamidine, and thioamide moieties. The ability of KlpD to simultaneously perform two distinct types of modifications is unprecedented for known YcaO proteins. The versatility of KlpD opens up possibilities for rational introduction of modifications into various peptide backbones.

AB - Non-heme iron(II) complexes of pentadentate N4Py ( N,N-bis(2-pyridylmethyl)- N bis(2-pyridyl)methylamine) type ligands undergo visible light-driven oxidation to their iron(III) state in the presence of O2 without ligand degradation. Under mildly basic conditions, however, highly selective base catalyzed ligand degradation with O2, to form a well-defined pyridyl-imine iron(II) complex and an iron(III) picolinate complex, is accelerated photochemically. Specifically, a pyridyl-CH2 moiety is lost from the ligand, yielding a potentially N4 coordinating ligand containing an imine motif. The involvement of reactive oxygen species other than O2 is excluded; instead, deprotonation at the benzylic positions to generate an amine radical is proposed as the rate determining step. The selective nature of the transformation holds implications for efforts to increase catalyst robustness through ligand design. PMID- 29601197 TI - Estimating Missing Unit Process Data in Life Cycle Assessment Using a Similarity Based Approach. AB - In life cycle assessment (LCA), collecting unit process data from the empirical sources (i.e., meter readings, operation logs/journals) is often costly and time consuming. We propose a new computational approach to estimate missing unit process data solely relying on limited known data based on a similarity-based link prediction method. The intuition is that similar processes in a unit process network tend to have similar material/energy inputs and waste/emission outputs. We use the ecoinvent 3.1 unit process data sets to test our method in four steps: (1) dividing the data sets into a training set and a test set; (2) randomly removing certain numbers of data in the test set indicated as missing; (3) using similarity-weighted means of various numbers of most similar processes in the training set to estimate the missing data in the test set; and (4) comparing estimated data with the original values to determine the performance of the estimation. The results show that missing data can be accurately estimated when less than 5% data are missing in one process. The estimation performance decreases as the percentage of missing data increases. This study provides a new approach to compile unit process data and demonstrates a promising potential of using computational approaches for LCA data compilation. PMID- 29601198 TI - A Generalized-Rate Model for Describing and Scaling Redox Kinetics in Sediments Containing Variable Redox-Reactive Materials. AB - This study developed a generalized modeling approach for describing and scaling redox reactions from reactive components to the sediments and their assemblages, using Cr(VI) reduction as an example. Batch experiments were performed to characterize the rates of Cr(VI) reduction in four Fe(II)-containing sediments and their assemblages. The experimental data were first used to calibrate a generalized-rate model of Cr(VI) reduction with generic rate parameters. The generalized-rate model was then used to describe the kinetics of Cr(VI) reduction in the sediment assemblages by linearly scaling the rate parameters from the individual sediments. Via comparison with the experimental results, this study found that the generalized-rate model with generic rate parameters can describe Cr(VI) reduction in individual sediments and their assemblages with different redox reactivity toward Cr(VI) reduction. The sediment-associated Fe(II) and its reactivity were found to be the key variables in the generalized model for describing the Cr(VI) reduction in the studied sediments. A three-step extraction method was subsequently developed to estimate the rate-specific Fe(II) pools that can facilitate the application of the scaling approach in field systems. PMID- 29601199 TI - Genetically Encoding Fluorosulfate-l-tyrosine To React with Lysine, Histidine, and Tyrosine via SuFEx in Proteins in Vivo. AB - Introducing new chemical reactivity into proteins in living cells would endow innovative covalent bonding ability to proteins for research and engineering in vivo. Latent bioreactive unnatural amino acids (Uaas) can be incorporated into proteins to react with target natural amino acid residues via proximity-enabled reactivity. To expand the diversity of proteins amenable to such reactivity in vivo, a chemical functionality that is biocompatible and able to react with multiple natural residues under physiological conditions is highly desirable. Here we report the genetic encoding of fluorosulfate-l-tyrosine (FSY), the first latent bioreactive Uaa that undergoes sulfur-fluoride exchange (SuFEx) on proteins in vivo. FSY was found nontoxic to Escherichia coli and mammalian cells; after being incorporated into proteins, it selectively reacted with proximal lysine, histidine, and tyrosine via SuFEx, generating covalent intraprotein bridge and interprotein cross-link of interacting proteins directly in living cells. The proximity-activatable reactivity, multitargeting ability, and excellent biocompatibility of FSY will be invaluable for covalent manipulation of proteins in vivo. Moreover, genetically encoded FSY hereby empowers general proteins with the next generation of click chemistry, SuFEx, which will afford broad utilities in chemical biology, drug discovery, and biotherapeutics.

AB - Gluco-azoles competitively inhibit glucosidases by transition-state mimicry and their ability to interact with catalytic acid residues in glucosidase active sites. We noted that no azole-type inhibitors described, to date, possess a protic nitrogen characteristic for 1 H-imidazoles. Here, we present gluco-1 H imidazole, a gluco-azole bearing a 1 H-imidazole fused to a glucopyranose configured cyclitol core, and three close analogues as new glucosidase inhibitors. All compounds inhibit human retaining beta-glucosidase, GBA1, with the most potent ones inhibiting this enzyme (deficient in Gaucher disease) on a par with glucoimidazole. None inhibit glucosylceramide synthase, cytosolic beta glucosidase GBA2 or alpha-glucosidase GAA. Structural, physical and computational studies provide first insights into the binding mode of this conceptually new class of retaining beta-glucosidase inhibitors. PMID- 29601201 TI - The Pentagonal Nature of Self-Assembled Silicon Chains and Magic Clusters on Ag(110). AB - The atomic structures of self-assembled silicon nanoribbons and magic clusters on Ag(110) substrate have been studied by high-resolution noncontact atomic force microscopy (nc-AFM) and tip-enhanced Raman spectroscopy (TERS). Pentagon-ring structures in Si nanoribbons and clusters have been directly visualized. Moreover, the vibrational fingerprints of individual Si nanoribbon and cluster retrieved by subnanometer resolution TERS confirm the pentagonal nature of both Si nanoribbons and clusters. This work demonstrates that Si pentagon can be an important element in building silicon nanostructures, which may find important applications for future nanoelectronic devices based on silicon. PMID- 29601202 TI - Benchmarking the Effective Fragment Potential Dispersion Correction on the S22 Test Set. AB - The usual modeling of dispersion interactions in density functional theory (DFT) is often limited by the use of empirically fitted parameters. In this study, the accuracies of the popular empirical dispersion corrections and the first principles derived effective fragment potential (EFP) dispersion correction are compared by computing the DFT-D and HF-D equilibria interaction energies and intermolecular distances of the S22 test set dimers. Functionals based on the local density approximation (LDA) and generalized gradient approximation (GGA), as well as hybrid functionals, are compared for the DFT-D calculations using coupled cluster CCSD(T) at the complete basis set (CBS) limit as the reference method. In general, the HF-D(EFP) method provides accurate equilibrium dimerization energies and intermolecular distances for hydrogen-bonded systems compared to the CCSD(T)/CBS reference data without using any empirical parameters. For dispersion-dominant and mixed systems, the structures and interaction energies obtained with the B3LYP-D(EFP) method are similar to or better than those obtained with the other DFT-D and HF-D methods. Overall, the first-principles derived -D(EFP) correction presents a robust alternative to the empirical -D corrections when used with the B3LYP functional for dispersion dominant and mixed systems or with Hartree-Fock for hydrogen-bonded systems. PMID- 29601203 TI - Crystallography and Molecular Arrangement of Polymorphic Monolayer J-Aggregates of a Cyanine Dye: Multiangle Polarized Light Fluorescence Optical Microscopy Study. AB - The molecular orientation in monolayer J-aggregates of 3,3-di(gamma-sulfopropyl) 5,5-dichlorotiamonomethinecyanine dye has been precisely estimated using improved linear polarization measurements in the fluorescence microscope in which a multiangle set of polarization data is obtained using sample rotation. The estimated molecular orientation supplemented with the previously established crystallographic constraints based on the analysis of the well-developed two dimensional J-aggregate shapes unambiguously indicate the staircase type of molecular arrangement for striplike J-aggregates with the staircases oriented along strips. The molecular transition dipoles are inclined at an angle of ~25 degrees to the strip direction, whereas the characteristic strip vertex angle ~45 degrees is formed by the [100] and [1-10] directions of the monoclinic unit cell. Measurements of the geometry of partially unwound tubes and their polarization properties support the model of tube formation by close-packed helical winding of flexible monolayer strips. In the tubes, the long molecular axes are oriented at a small angle in the range of 5-15 degrees to the normal to the tube axis providing low bending energy. At a nanoscale, high-resolution atomic force microscopy imaging of J-aggregate monolayers reveals a complex quasi one-dimensional organization. PMID- 29601204 TI - pH-Dependence of Binding Constants and Desorption Rates of Phosphonate- and Hydroxamate-Anchored [Ru(bpy)3]2+ on TiO2 and WO3. AB - The binding constants and rate constants for desorption of the modified molecular dye [Ru(bpy)3]2+ anchored by either phosphonate or hydroxamate on the bipyridine ligand to anatase TiO2 and WO3 have been measured. In aqueous media at pH 1-10, repulsive electrostatic interactions between the negatively charged anchor and the negatively charged surface govern phosphonate desorption under neutral and basic conditions for TiO2 anatase due to the high acidity of phosphonic acid (p Ka,4 = 5.1). In contrast, the lower acidity of hydroxamate (p Ka,1 = 6.5, p Ka,2 = 9.1) leads to little change in adsorption/desorption properties as a function of pH from 1 to 7. The binding constant for hydroxamate is 103 in water, independent of pH in this range. These results are true for WO3 as well, but are not reported at pH > 4 due to its Arrhenius acidity. Kinetics for desorption as a function of pH are reported, with a proposed mechanism for phosphonate desorption at high pH being the electrostatic repulsion of negative charges between the surface and the anionic anchor. Further, the hydroxamic acid anchor itself is likely the site of quasi-reversible redox activity in [Ru(bpy)2(2,2'-bpy-4,4' (C(O)N(OH))2)]2+, which does not lead to any measurable deterioration of the complex within 2 h of dark cyclic voltammogram scans in aqueous media. These results posit phosphonate as the preferred anchoring group under acidic conditions and hydroxamate for neutral/basic conditions.

AB - Quantum emitters in solids are being developed for a range of quantum technologies, including quantum networks, computing, and sensing. However, a remaining challenge is the poor photon collection due to the high refractive index of most host materials. Here we overcome this limitation by introducing monolithic parabolic reflectors as an efficient geometry for broadband photon extraction from quantum emitter and experimentally demonstrate this device for the nitrogen-vacancy (NV) center in diamond. Simulations indicate a photon collection efficiency exceeding 75% across the visible spectrum and experimental devices, fabricated using a high-throughput gray scale lithography process, demonstrating a photon extraction efficiency of (41 +/- 5)%. This device enables a raw experimental detection efficiency of (12 +/- 1)% with fluorescence detection rates as high as (4.114 +/- 0.003) * 106 counts per second (cps) from a single NV center. Enabled by our deterministic emitter localization and fabrication process, we find a high number of exceptional devices with an average count rate of (3.1 +/- 0.9) * 106 cps. PMID- 29601206 TI - Non-Plasmonic SERS with Silicon: Is It Really Safe? New Insights into the Optothermal Properties of Core/Shell Microbeads. AB - Silicon is one of the most interesting candidates for plasmon-free surface enhaced Raman scattering (SERS), because of its high-refractive index and thermal stability. However, here we demonstrate that the alleged thermal stability of silicon nanoshells irradiated by conventional Raman laser cannot be taken for granted. We investigated the opto-thermal behavior of SiO2/Si core/shell microbeads (Si-rex) irradiated with three common Raman laser sources (lambda = 532, 633, 785 nm) under real working conditions. We obtained an experimental proof of the critical role played by bead size and aggregation in heat and light management, demonstrating that, in the case of strong opto-thermal coupling, the temperature can exceed that of the melting points of both core and shell components. In addition, we also show that weakly coupled beads can be utilized as stable substrates for plasmon-free SERS experiments. PMID- 29601207 TI - Nonsurgical Treatments of Patellar Tendinopathy: Multiple Injections of Platelet Rich Plasma Are a Suitable Option: A Systematic Review and Meta-analysis. AB - BACKGROUND: Patellar tendinopathy is a condition characterized by anterior knee activity-related pain. It has a high incidence among athletes engaged in jumping sports and may become a chronic condition. Nonoperative management is the first choice in these patients, and several nonsurgical treatment options have been proposed. Nonetheless, clear indications on the most effective approach to address patellar tendinopathy are still lacking. PURPOSE: To analyze the evidence on nonoperative options to treat chronic patellar tendinopathy through a systematic review of the literature and to perform a meta-analysis to identify the most effective nonsurgical option. STUDY DESIGN: Systematic review and meta analysis. METHODS: The search was conducted with the PubMed and Cochrane databases on January 4, 2017. All clinical English-language reports of any level of evidence on nonsurgical treatment of patellar tendinopathy were included. The quality of each article was assessed by use of the Coleman score. A meta-analysis was performed on all articles reporting the Victorian Institute of Sport Assessment scale for patellar tendinopathy to evaluate the results of the most described treatments. RESULTS: A total of 70 studies involving 2530 patients were included in the qualitative data synthesis. The Coleman score showed an overall poor study quality. The most described treatment groups that could be included in the meta-analysis were reported in 22 studies on eccentric exercise, extracorporeal shockwave therapy (ESWT), and platelet-rich plasma (PRP). Single and multiple PRP injections were evaluated separately. Eccentric exercise therapies obtained the best results ( P < .05) at short-term (<6 months, mean 2.7 +/- 0.7 months). However, multiple injections of PRP obtained the best results ( P < .05), followed by ESWT and eccentric exercise, at long-term follow-up (>=6 months, mean 15.1 +/- 11.3 months). CONCLUSION: The literature documents several nonsurgical approaches for the treatment of chronic patellar tendinopathy with important limitations in terms of study quality. The available evidence showed an overall positive outcome, but some differences have been highlighted. Eccentric exercises may seem the strategy of choice in the short-term, but multiple PRP injections may offer more satisfactory results at long-term follow-up and can be therefore considered a suitable option for the treatment of patellar tendinopathy. PMID- 29601208 TI - Performance and Return to Sport After Tommy John Surgery Among Major League Baseball Position Players. AB - BACKGROUND: The anterior bundle of the medial ulnar collateral ligament (UCL) is the primary restraint to valgus stress at the elbow and is often injured among overhead throwing athletes. Despite prevention strategies, injuries to the elbow UCL are on the rise. PURPOSE: To determine (1) the return-to-sport (RTS) rate of Major League Baseball (MLB) position players after elbow medial UCL reconstruction, (2) postoperative career length and games per season, (3) pre- and postoperative performance, (4) postoperative performance versus matched control players, and (5) whether position players changed positions after UCL reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: MLB players who underwent elbow UCL reconstruction were identified (cases). Demographic and performance data were collected for each player. Matched controls were identified. RTS in MLB was defined as playing in at least 1 MLB game after UCL reconstruction. Comparisons between case and control groups and pre- and postoperative time points were made via paired samples Student t tests. RESULTS: Thirty-three players (34 surgical procedures) were identified with a mean +/- SD age of 30.2 +/- 4.2 years and a mean experience in the MLB of 6.3 +/- 3.9 years at the time of surgery. Twenty-eight players (84.8%) were able to RTS in MLB at a mean 336.9 +/- 121.8 days. However, players >=30 years old demonstrated a significantly lower RTS rate (53.3%) than players <30 years old (89.4%; P < .05). Catchers had a significantly shorter postoperative career length (2.8 +/- 1.8 years) versus matched controls (6.1 +/- 1.9 years; P < .05). Outfielders had a significantly lower wins above replacement postoperatively (0.8 +/- 0.7) versus preoperatively (1.5 +/- 1.1; P < .05). There were no performance differences between cases and matched controls. Twelve players (48%) returned to a different position postoperatively. CONCLUSION: The RTS rate for MLB position players after elbow UCL reconstruction is similar to that of pitchers. Catchers had a significantly shorter career length than that of matched controls. Outfielders performed worse postoperatively versus preoperatively. There is a high rate of position change after Tommy John surgery for infielders and outfielders. PMID- 29601209 TI - Changes in mood after screening for antenatal anxiety and depression. AB - BACKGROUND: Screening programmes with referral are a valuable strategy for mitigating consequences of perinatal depression on mothers and their families. The effectiveness of these screening programmes needs to be measured. One potential problem in assessing outcomes is measurement reactivity where the actual measure results in changes in the people being measured. AIM: The aim of this article is to explain the mechanisms and circumstances by which measurement reactivity occurred in a sample of antenatal women who participated in a screening interview. METHODS: Fifty-five women who participated in an antenatal screening interview in their second trimester were re-interviewed in their third trimester. These qualitative interviews were conducted between September 2015 and April 2016. RESULTS: The qualitative data suggested that measurement reactivity occurred through mechanisms such as the disclosure, gaining self-knowledge, validation of experiences, and personal agency which resulted in them seeking out support from others. CONCLUSION: Although the screening interview appeared to improve women's outcomes, this may have occurred through measurement reactivity. This needs to be considered when designing studies that aim to assess the effectiveness of screening with intervention for antenatal depression.

AB - Noble metal nanoparticles loaded smart polymer microgels have gained much attention due to fascinating combination of their properties in a single system. These hybrid systems have been extensively used in biomedicines, photonics, and catalysis. Hybrid microgels are characterized by using various techniques but UV/Vis spectroscopy is an easily available technique for characterization of noble metal nanoparticles loaded microgels. This technique is widely used for determination of size and shape of metal nanoparticles. The tuning of optical properties of noble metal nanoparticles under various stimuli can be studied using UV/Vis spectroscopic method. Time course UV/Vis spectroscopy can also be used to monitor the kinetics of swelling and deswelling of microgels and hybrid microgels. Growth of metal nanoparticles in polymeric network or growth of polymeric network around metal nanoparticle core can be studied by using UV/Vis spectroscopy. This technique can also be used for investigation of various applications of hybrid materials in catalysis, photonics, and sensing. This tutorial review describes the uses of UV/Vis spectroscopy in characterization and catalytic applications of responsive hybrid microgels with respect to recent research progress in this area. PMID- 29601211 TI - Food insecurity and coping strategies in a marine protected area in southeastern Tanzania. AB - This article examines the perceived food security and coping strategies in coastal communities located in a marine protected area (MPA) in southeastern Tanzania. Drawing on fieldwork concentrated in a representative coastal village, the article illustrates how women in particular understand their food security situation in relation to the MPA. Data from interviews with 120 women suggest that the majority of the households in the study area were food insecure. Only few respondents, however, specifically attributed their food insecurity to the MPA's presence in their village, suggesting that food security is multidimensional and is undergirded by several interrelated factors that vary over time. The findings query the assertion that MPAs can and do contribute to improved food security in coastal populations through increased fish biomass or ecotourism projects. PMID- 29601213 TI - It's Time to Develop a New "Draft Test Protocol" for a Mars Sample Return Mission (or Two...). AB - The last time NASA envisioned a sample return mission from Mars, the development of a protocol to support the analysis of the samples in a containment facility resulted in a "Draft Test Protocol" that outlined required preparations "for the safe receiving, handling, testing, distributing, and archiving of martian materials here on Earth" (Rummel et al., 2002 ). This document comprised a specific protocol to be used to conduct a biohazard test for a returned martian sample, following the recommendations of the Space Studies Board of the US National Academy of Sciences. Given the planned launch of a sample-collecting and sample-caching rover (Mars 2020) in 2 years' time, and with a sample return planned for the end of the next decade, it is time to revisit the Draft Test Protocol to develop a sample analysis and biohazard test plan to meet the needs of these future missions.

AB - Purpose We investigated the effect on outcome of measurable or minimal residual disease (MRD) status after each induction course to evaluate the extent of its predictive value for acute myeloid leukemia (AML) risk groups, including NPM1 wild-type (wt) standard risk, when incorporated with other induction response criteria. Methods As part of the NCRI AML17 trial, 2,450 younger adult patients with AML or high-risk myelodysplastic syndrome had prospective multiparameter flow cytometric MRD (MFC-MRD) assessment. After course 1 (C1), responses were categorized as resistant disease (RD), partial remission (PR), and complete remission (CR) or complete remission with absolute neutrophil count < 1,000/uL or thrombocytopenia < 100,000/MUL (CRi) by clinicians, with CR/CRi subdivided by MFC MRD assay into MRD+ and MRD-. Patients without high-risk factors, including Flt3 internal tandem duplication wt/- NPM1-wt subgroup, received a second daunorubicin/cytosine arabinoside induction; course 2 (C2) was intensified for patients with high-risk factors. Results Survival outcomes from PR and MRD+ responses after C1 were similar, particularly for good- to standard-risk subgroups (5-year overall survival [OS], 27% RD v 46% PR v 51% MRD+ v 70% MRD-; P < .001). Adjusted analyses confirmed significant OS differences between C1 RD versus PR/MRD+ but not PR versus MRD+. CRi after C1 reduced OS in MRD+ (19% CRi v 45% CR; P = .001) patients, with a smaller effect after C2. The prognostic effect of C2 MFC-MRD status (relapse: hazard ratio [HR], 1.88 [95% CI, 1.50 to 2.36], P < .001; survival: HR, 1.77 [95% CI, 1.41 to 2.22], P < .001) remained significant when adjusting for C1 response. MRD positivity appeared less discriminatory in poor-risk patients by stratified analyses. For the NPM1-wt standard-risk subgroup, C2 MRD+ was significantly associated with poorer outcomes (OS, 33% v 63% MRD-, P = .003; relapse incidence, 89% when MRD+ >= 0.1%); transplant benefit was more apparent in patients with MRD+ (HR, 0.72; 95% CI, 0.31 to 1.69) than those with MRD- (HR, 1.68 [95% CI, 0.75 to 3.85]; P = .16 for interaction). Conclusion MFC-MRD can improve outcome stratification by extending the definition of partial response after first induction and may help predict NPM1-wt standard risk patients with poor outcome who benefit from transplant in the first CR. PMID- 29601214 TI - A novel clinical test for assessing patellar cartilage changes and its correlation with magnetic resonance imaging and arthroscopy. AB - Controversy still exists regarding the best clinical assessment test for chondromalacia patellae (CMP). Our study aims to evaluate the specificity and sensitivity of a novel clinical test for CMP, the "Patella Slide Test" (PST) against the findings of magnetic resonance imaging (MRI) and arthroscopy. We included 221 consecutive patients planned for elective knee arthroscopic surgery. An MRI scan of the symptomatic knee was performed prior to surgery. On the day of surgery, each patient was examined using the PST followed by a knee arthroscopy to assess the quality of the chondral surfaces of the patellofemoral joint. The MRI and PST results were compared against the arthroscopic findings that served as the gold standard. The PST (0.89) was statistically more sensitive than MRI (0.67) in diagnosing CMP. The PST (0.89) also had a greater negative predictive value (NPV) than MRI (0.74). However, MRI (0.94) was more specific than the PST (0.85). The differences in accuracy and positive predictive value of the PST versus MRI were not statically significant. In conclusion, the PST shows high sensitivity and has a greater NPV than MRI as a clinical test for diagnosing CMP.

AB - OBJECTIVE: To estimate the cleft lip with or without cleft palate (CL/P) prevalence among births between 2006 and 2012 in Fangshan district of Beijing, China. DESIGN: Surveillance data analysis. SETTING: All hospitals that provide obstetric services in the district. PATIENTS: The CL/P cases presented for this report were from 13 weeks' gestation to 7 days postpartum. MAIN OUTCOME MEASURES: The CL/P prevalence was defined as the number of cases per 10 000 births, including live births and stillbirths at 28 weeks' gestation or beyond. RESULTS: The overall CL/P prevalence was 18.9 (95% confidence interval [CI]: 15.1-22.7) per 10 000 births. From 2006 to 2012, the CL/P prevalence was 19.3, 20.2, 10.9, 16.1, 17.5, 25.4, and 22.3 per 10 000 births; annually, no significant change was noted ( Pfor trend = .311). The prevalence of cleft palate, cleft lip, and cleft lip and palate were 3.4 (95% CI: 2.0-5.4), 6.2 (95% CI: 4.2-8.8), and 9.4 (95% CI: 6.9-12.4) per 10 000 births, respectively. The CL/P prevalence among the nonpermanent residents (31.4 per 10 000 births) was 2.31 times that of permanent residents (13.6 per 10 000 births). Among nonpermanent residents, the CL/P prevalence showed an upward trend over the study period ( Pfor trend = .036), that increased from 38.8 (95% CI: 16.5-76.6) per 10 000 births in 2006 to 54.6 (95% CI: 25.7-100.4) per 10 000 births in 2012. CONCLUSIONS: The overall CL/P prevalence was stable in the Fangshan district. However, the CL/P prevalence of the nonpermanent residents increased significantly.

AB - Autism spectrum disorder (ASD) is diagnosed more often in boys than in girls; however, little is known about the nature of this sex/gender discrepancy or how it relates to diagnostic assessment practices. This study examined the performance of the Social Communication Questionnaire (SCQ) in screening for ASD among boys and girls. Data were drawn from the South Carolina Children's Educational Surveillance Study, a population-based study of ASD prevalence among children 8-10 years of age. Analyses were conducted using SCQ data from 3,520 children, with direct assessment data from 272 with elevated SCQ scores. A bifactor model based on the Diagnostic and Statistical Manual of Mental Disorders's (5th ed.) two ASD symptom domains fit the data well and performed slightly better for girls. In the general population sample, girls exhibited fewer social communication/interaction and restricted-repetitive behavior symptoms than boys. In the direct assessment sample, however, girls with ASD showed greater impairment in social communication/interaction than boys with ASD. Items pertaining to social communication/interaction problems at ages 4-5 were among the most diagnostically efficient overall and particularly for girls. Similarly, receiver operating characteristic analyses suggested that the SCQ performs adequately among boys and well among girls. Results support the use of the SCQ in screening for ASD but do not indicate sex/gender-specific cutoffs. Girls with ASD may exhibit pronounced intraindividual deficits in social communication/interaction compared to male peers with ASD and female peers without ASD. Although more research is needed, careful attention to social communication/interaction deficits around 4-5 years of age may be especially useful for assessing ASD in girls. PMID- 29601217 TI - The effect of patellar taping on lower extremity running kinematics in individuals with patellofemoral pain syndrome. AB - PURPOSE: To investigate the effects of patellar taping (Leukotape(r) (LT), Pinetown, South Africa, Kinesio Tape (KT), Dortmund, Germany, or no tape) on lower extremity kinematics in runners with and without patellofemoral pain syndrome (PFPS). METHODS: In total, 20 healthy individuals and 12 with PFPS ran on a treadmill under different taping conditions and lower extremity kinematics and stride characteristics were obtained using Peak Motus Software, Colorado, USA. Data were analyzed using descriptive statistics and mixed factorial analysis of variance (p < 0.05). RESULTS: Significant taping effects were found for hip (F(2,60) = 16.79, p = 0.0001) and knee (F(2,60) = 17.27, p = 0.0001) flexion angles at initial contact, and peak hip flexion angles during swing (F(2,60) = 6.55, p = 0.003). Increased flexion was noted with LT more than KT and no tape conditions. Similarly, peak knee flexion angles during stance (F(2,60) = 3.51, p = 0.03) and flight time (F(2,60) = 5.01, p = 0.01) revealed significant taping effects, with LT resulting in more flexion (p = 0.04) and shorter flight times (p = 0.01) than the no tape condition. Furthermore, a significant taping effect was seen for peak knee flexion angle during swing (F(2,60) = 4.96, p = 0.01), with the KT resulting in less flexion than LT (p = 0.04) and no tape conditions (p = 0.04). CONCLUSION: The application of tape during running may impact on hip and knee flexion angles at initial contact, as well as flight time. PMID- 29601218 TI - Treadmill associated head injuries on the rise: an 18 year review of U.S. emergency room visits. AB - OBJECTIVE: The treadmill is the most commonly used aerobic exercise equipment with studies showing many gym-related injuries are attributed to treadmills. The purpose of this study is to examine the incidence of treadmill-associated head injuries within the US. METHODS: Retrospective data from 1997 to 2014 was collected via the National Electronic Injury Surveillance System, which provides annual es7timates of injuries associated with consumer products. Patients over 18 years who sustained treadmill-associated head injuries were included, and the estimated annual incidence was determined. RESULTS: An estimated 4929 patients presented to US emergency departments with a head injury while exercising on a treadmill between 1997 and 2014. A >1000% increase in the number of head injuries was observed over the study period (p-value <0.001). Patients over 50 had a 14 times greater risk of admission than younger patients (p-value <0.001). Injuries were greater in women than men. CONCLUSION: Our study demonstrates a significant increase treadmill-associated head injuries from 1997 to 2014. This phenomenon is most pronounced in older and female populations. The exact etiology of this large increase remains unclear. Education on the proper use of treadmills as well as further investigation into the cause of the increase are warranted. PMID- 29601219 TI - An examination of the perceived impact of a continuing interprofessional education experience on opiate prescribing practices. AB - Chronic pain is increasingly recognized as a public health problem. We assessed the effectiveness of a multi-modal, interprofessional educational approach aimed at empowering healthcare professionals to make deliberative changes, especially in opiate prescribing practices. Education activities included enduring webcasts, regional interprofessional roundtable events, and state-level conference presentations within targeted Kentucky and West Virginia regions of the United States. Over 1,000 participants accessed the various activities. For the live events, the largest groups reached included nurses (38.1%), nurse practitioners (31.2%), and physicians (22.1%). In addition to our reach, higher levels of educational effectiveness were measured, specifically, learner's intentions to change practice patterns, confidence in meeting patient's needs, and knowledge of pain management guidelines. The majority of the conference (58%) and roundtable (69%) participants stated they intend to make a practice change in one or more areas of chronic pain patient management in post-event evaluation. Differences in pre- and post-activity responses on the measures of confidence and knowledge, with additional comparison to a control population who were not in attendance, were analyzed using non-parametric tests of significance. While neither activity produced significant changes in confidence from pre-activity, participants were more confident post-activity than their control group peers. There were significant changes in knowledge for both live event and webcast participants. Impactful chronic pain continuing the education that emphasizes collaborative care is greatly needed; these results show that the approaches taken here can impact learner's knowledge and confidence, and hold potential for creating change in how opioid prescribing is managed. PMID- 29601220 TI - Is perceived force an accurate method of regulating exercise load for the neck? AB - OBJECTIVE: Patient perceived level of force is commonly used to regulate exercise load. This study determined the accuracy of perceived force as a method of regulating exercise load for the cervical flexors and extensors. METHODS: Thirty healthy individuals performed submaximal isometric cervical flexion and extension exercise at perceived intensities (25%, 50%, and 75%) of their maximal voluntary contraction (MVC) with no feedback in a neck dynamometer. Measurements of "actual" versus "perceived" force levels were compared before and after the performance of an MVC. Data were analyzed descriptively and the relationship between performance error, test, and participant factors examined. RESULTS: With the exception of the 25% MVC extension trials post-MVC, an underestimation of force was observed over all conditions that worsened as the target force increased (50% and 75%) with only some improvement following the experience of an MVC (p < 0.001). Linear mixed modeling indicated participants familiar with exercise may have better accuracy (p = 0.07). CONCLUSION: Regulating isometric resistance exercise load of the neck based on a perceived proportion of MVC force may only be accurate at low intensities (25% MVC) but not for moderate to high (50-75%) intensities. PMID- 29601221 TI - Comparison of hip extensor muscle activity including the adductor magnus during three prone hip extension exercises. AB - OBJECTIVES: This study compared the role of the adductor magnus muscle (Amag) as a hip extensor while performing active prone hip extension (PHE), PHE with hip adduction (PHE-ADD), and PHE with hip abduction (PHE-ABD) with the gluteus maximus (Gmax) and hamstrings. METHODS: The study recruited 22 healthy participants. Electromyography data were recorded from the Amag, Gmax, and medial and lateral hamstrings during PHE, PHE-ADD, and PHE-ABD. Normalized electromyographic data were examined using one-way, repeated-measures analyses of variance. RESULTS: The magnitude of the Amag, Gmax, and hamstring activations did not differ significantly while performing PHE (p = 0.41). Furthermore, the Amag and hamstring activations were significantly greater than the Gmax activation when performing PHE-ADD (p < 0.05). The Gmax showed significantly greater activation during PHE-ABD than the Amag and medial and lateral hamstrings (p < 0.05). CONCLUSIONS: Based on these results, we advocate including the Amag as a hip extensor during the PHE test or exercise. Our preliminary results have the potential to be applied directly to the PHE test, for investigating the muscle activation pattern of the Amag with the Gmax and hamstrings in patients with hip or lower back pain. PMID- 29601222 TI - Effects of dance-based movement therapy on balance, gait, and psychological functions in severe cerebellar ataxia: A case study. AB - PURPOSE: Individuals in the later stages of cerebellar ataxia usually experience serious balance and immobility problems. Currently, there is a lack of adequate rehabilitative programs for individuals with severe cerebellar ataxia that can help improve ataxia-related motor impairment. The purpose of the present study was to explore the potential physiotherapeutic benefits of partnered dance on balance, motor functions, and psychological well-being in an individual demonstrating severe cerebellar ataxia symptoms. METHODS: The individual was a 39 year-old male diagnosed with cerebellar atrophy. He had the disease for more than 15 years prior to the study. The individual attended 24 intervention sessions over an 8-week period of dance-based movement training that aimed to improve his balance and postural stability by facilitating the perception and control of static and dynamic balance movements and body alignment. RESULTS: The individual demonstrated improvements in independent standing balance, gait characteristics, and functional mobility. In addition, improvements in self-reported depression and quality of life scores were observed after completion of the intervention. CONCLUSION: Although interpreting the findings of this study is limited to a single participant, partnered dance could be a suitable alternative physiotherapeutic intervention method for people with severely impaired mobility due to cerebellar dysfunction. PMID- 29601223 TI - Providing no-cost transport to patients in an underserved area: Impact on access to physical therapy. AB - BACKGROUND: Barriers to accessing outpatient health care services are common and contribute to poor health outcomes. We describe the efforts of a private practice physical therapy (PT) clinic to reduce these barriers by offering a door-to-door van service at no cost to patients. METHODS: Clinic records and national census databases were retrospectively reviewed to explore the impact of offering no-cost van rides to patients attending outpatient PT appointments. We used descriptive statistics and linear regression to describe volume of utilization of the van service over a 40-month period. Paired t-tests compared PT clinic attendance rates (percentage of scheduled visits that were attended) before and after implementation of the van service. RESULTS: Use of the van service increased significantly over time, from a mean of 83 riders per month in 2010 to 205 riders per month in 2013 (p < 0.001). Overall clinic attendance rate increased from 80.1% to 84.1% after implementation of the service (p = 0.002). Following introduction of the van service, 48% of patients using the van, compared to 25% of clinic patients overall, were uninsured or insured by Medicaid. CONCLUSION: Use of the van service increased over time, and availability of no-cost van transportation was associated with increased visit attendance for patients at an outpatient PT clinic. PMID- 29601224 TI - Physical therapists' perception of workplace ethics in an evolving health-care delivery environment: a cross-sectional survey. AB - Physical therapists are trained and obligated to deliver optimal health care and put patients first above all else. In the changing health-care environment, health-care organizations are grappling with controlling cost and increasing revenues. Moral distress may be created when physical therapists' desire to provide optimal care conflicts with their organization's goals to remain financially viable or profitable. Moral distress has been associated with low perception of ethical environment, professional burnout, and high turnover in organizations. This study identified groups who may be vulnerable to low perception of organizational ethical environment and identified self-reported strategies to remedy these perceptions. An ethics environment questionnaire was mailed to a random sample of 1200 physical therapists in Georgia. Respondents (n = 340) were analyzed by age, workplace setting, and position in organization. Therapists working in skilled nursing/assisted living environments scored the lowest on the questionnaire and voiced concerns regarding their ethical work environments. Owners and executives perceived their organizations to be more ethical than front-line clinicians. Respondent concerns included high productivity standards, aggressive coding/billing policies, decreased reimbursement, and increased insurance regulation. Possible solutions included more frequent communication between management and clinicians about ethics, greater professional autonomy, and increased training in business ethics and finance. PMID- 29601225 TI - Functional basic reading skills in Williams syndrome. AB - This study investigated whether individuals with Williams syndrome (WS) can attain a functional level of basic reading skills. The Study also investigated broader cognitive factors associated with reading ability in individuals with WS. Thirty individuals with WS participated in this study (mean chronological age 21 years and mean mental age 7 years 7 months). The results supported our hypotheses that: firstly, reading abilities would be heterogeneous in WS; secondly, at least some WS individuals are capable of achieving a functional basic reading level; and thirdly, on average, WS individuals would find reading of nonwords more difficult than reading of regular and irregular words. Moreover, higher reading ability was found to be associated with increased outcomes in adaptive functioning, in particular, Written and Expressive Communication skills and Community Living skills, highlighting the potential benefits of developing reading abilities in WS. Although Intelligence Quotient (IQ) was related to overall basic reading ability generally, it was not found to be a determining factor in reading subtypes. Several cognitive skills known to be related to reading ability in typically developing individuals were found to be associated with reading performance and reading subtypes. Implications for appropriate reading instruction are discussed. PMID- 29601226 TI - Persons' various experiences of learning processes in patient education for osteoarthritis, a qualitative phenomenographic approach. AB - BACKGROUND: Patient education (PE) is a core treatment of osteoarthritis (OA) with the aim to increase persons' knowledge, self-efficacy, and empowerment. OBJECTIVE: To describe person's various experiences of learning processes in PE for OA. DESIGN: Phenomenography. METHOD: Semi-structured interviews were performed with the same persons, pre- (11) and post- (9) education. RESULTS: Various experiences on learning processes were found and were described in an outcome space. Achieving knowledge describes self-regulated learning and strongly relates to Control, which describes a high order cognitive learning skill, and minor to Confirm, which describes a cognitive learning skill based on recognition and application. Receiving knowledge describes the expectancy of learning regulated from the educator and strongly relates to Comply, which describes a low order cognitive learning skill, and minor to Confirm. CONCLUSION: Different experiences of motivation and learning impact on persons' learning processes which, in turn, influence the persons' capability to accomplish self-efficacy and empowerment. The outcome space may serve as a basis for discussions between healthcare educators involved in PE to better understand what learning implies and to develop PE further. PMID- 29601227 TI - The use of pain neuroscience education in older adults with chronic back and/or lower extremity pain. AB - INTRODUCTION: Chronic pain due to musculoskeletal disorders is the leading cause of disability among older adults and is associated with a lower quality of life, reduced function, and increased risk of institutionalization. Pain Neuroscience Education (PNE) has demonstrated effectiveness in reducing pain and improving pain self-efficacy in individuals under 60 years of age, but there is a paucity of research examining its use with older adults. If PNE has similar effects in older adults, it has the potential to be a useful non-pharmacological intervention for this population. METHODS: This quasi-experimental feasibility study included 25 subjects over the age of 65 with a 3 month or greater history of lower back and/or lower extremity pain. Subjects participated in two semi standardized one-on-one PNE sessions and were asked to read a booklet (Why Do I Hurt, Louw, International Spine and Pain Institute, USA) in between sessions. Subjects' perception of PNE was measured after the second session and gait speed, pain disability, and fear of movement were measured pre- and post-PNE. RESULTS: Subjects consistently reported a positive experience with PNE. There were statically significant positive improvements in gait speed, pain disability, and fear of movement after the intervention. CONCLUSION: PNE is a feasible and potentially efficacious treatment for older adults with chronic pain. PMID- 29601228 TI - Evaluation of three measures of cardiorespiratory fitness in independently ambulant stroke survivors. AB - Measuring cardiorespiratory fitness (CRF) in the stroke population is challenging. Currently, the recommended method is a graded exercise test (GXT) on an ergometer such as a treadmill or cycle, which may not always be possible. We investigated whether walking tests such as the six-minute walk test (6MWT) and the shuttle walk test (SWT) may be appropriate indicators of CRF in the stroke population. Twenty-three independently ambulant stroke survivors (11 men, age 61.5 +/- 18.4 years) within one-year post stroke performed the 6MWT, SWT, and cycle GXT, during which peak oxygen consumption (VO2peak) and heart rate (HRpeak) were recorded. There were no differences (p > 0.05) in mean VO2peak among the three tests (min-max: 17.08-18.09 mL kg-1 min-1). For individuals, small discrepancies in VO2peak between the 6MWT and other tests were greater with higher fitness levels. HRpeak was significantly (p = 0.005) lower during the 6MWT. Correlations between VO2peak and performance measures within each test were high (6MWT VO2peak and distance: r = 0.78, SWT VO2peak and shuttles: r = 0.73, cycle GXT VO2peak and workload: r = 0.77) suggesting the performance measures may be clinically useful as proxy measures of CRF. Common comorbidities, such as lower-limb joint pain and poor balance, and participant's fastest walking speed, should inform the choice of CRF test. PMID- 29601229 TI - Immunolocalization of Surfactant Proteins SP-A, SP-B, SP-C, and SP-D in Infantile Labial Glands and Mucosa. AB - Surfactant proteins in different glandular structures of the oral cavity display antimicrobial activity for protection of invading microorganisms. Moreover, they are involved in lowering liquid tension in fluids and facilitate secretion flows. Numerous investigations for studying the occurrence of surfactant proteins in glandular tissues were performed using different methods. In the oral cavity, minor salivary glands secrete saliva continuously for the maintenance of a healthy oral environment. For the first time, we could show that infantile labial glands show expression of the surfactant proteins (SP) SP-A, SP-B, SP-C, and SP-D in acinar cells and the duct system in different intensities. The stratified squamous epithelium of the oral mucosa revealed positive staining for SPs in various cell layers. PMID- 29601230 TI - Test-retest reliability, validation, and "minimal detectable change" scores for frequently reported tests of objective physical function in patients with non dialysis chronic kidney disease. AB - Physical function is an important outcome in chronic kidney disease (CKD). We aimed to establish the reliability, validity, and the "minimal detectable change" (MDC) of several common tests used in renal rehabilitation and research. In a repeated measures design, 41 patients with CKD not requiring dialysis (stage 3b to 5) were assessed at an interval of 6 weeks. The tests were the incremental shuttle walk test (ISWT), "sit-to-stand" (STS) test, estimated 1 repetition maximum for quadriceps strength (e1RM), and VO2peak by cardiopulmonary exercise testing (CPET). Reliability was assessed using intraclass correlation coefficient and Bland-Altman analysis, and absolute reliability by standard error of measurement and MDC. The ISWT, STS-60, e1RM, and CPET had "good" to "excellent" reliability (0.973, 0.927, 0.927, and 0.866), respectively. STS-5 reliability was poor (0.676). The MDC is ISWT, 20 m; STS-5, 7.5 s; STS-60, 4 reps; e1RM, 6.4 kg; VO2peak, 2.8 ml/kg/min. There was strong correlation between the ISWT and VO2peak (r = 0.73 and 0.74). While there was poor correlation between the STS-5 and e1RM (r = 0.14 and 0.47), better correlation was seen between STS-5 and ISWT (r = 0.55 and 0.74). In conclusion, the ISWT, STS-60, e1RM, and CPET are reliable tests of function in CKD. The ISWT is a valid means of exercise capacity. The MDC can help researchers and rehabilitation professionals interpret changes following an intervention. PMID- 29601231 TI - Activation of the Small GTPase Rap1 Inhibits Choroidal Neovascularization by Regulating Cell Junctions and ROS Generation in Rats. AB - PURPOSE: Choroidal neovascularization (CNV) is a common vision-threatening complication associated with many fundus diseases. The retinal pigment epithelial (RPE) cell junction barrier has critical functions in preventing CNV, and oxidative stress can cause compromise of barrier integrity and induce angiogenesis. Rap1, a small guanosine triphosphatase (GTPase), is involved in regulating endothelial and epithelial cell junctions. In this work, we explored the function and mechanism of Rap1 in CNV in vivo. METHODS: A laser-induced rat CNV model was developed. Rap1 was activated through intravitreal injection of the Rap1 activator 8CPT-2'-O-Me-cAMP (8CPT). At 14 days after laser treatment, CNV size in RPE/choroid flat mounts was measured by fluorescein isothiocyanate dextran staining. Expression of vascular endothelial growth factor (VEGF) and cell junction proteins in RPE/choroid tissues were analyzed by western blots and quantitative real-time PCR assays. Reactive oxygen species (ROS) in RPE cells were detectedbydichloro-dihydro-fluorescein diacetate assays. The antioxidant apocynin was intraperitoneally injected into rats. RESULTS: Activating Rap1 by 8CPT significantly reduced CNV size and VEGF expression in the rat CNV model. Rap1 activation enhanced protein and mRNA levels of ZO-1 and occludin, two tight junction proteins in the RPE barrier. In addition, reducing ROS generation by injection of apocynin, a NADPH oxidase inhibitor, inhibited CNV formation. Rap1 activation reduced ROS generation and expression of NADPH oxidase 4. CONCLUSIONS: Rap1 activation inhibits CNV through regulating barrier integrity and ROS generation of RPE in vivo, and selectively activating Rap1 may be a way to reduce vision loss from CNV. PMID- 29601232 TI - Aging and exercise: Perceptions of the active lived-body. AB - Exploring older people's evocation of their positive experiences of aging has been proposed as a counterweight to the Western stereotype of aging as a process of decline. The aim of this article is to explore how aging women, who participate regularly in group exercise classes, perceive their own bodies and the bodies of others. This article reports on the findings from interviews with 16 women between the age of 70 and 85. We analyzed the data using qualitative content analysis. Two overarching and interrelated themes concerning body perception emerged from the interviews: "The aging body and appearance" and "The body as subject and object." The binary discourse of old age, as either a decline or a success appears in our findings. The training contributes to a sense of well being experienced through perceived increased physical abilities, self- image and self-esteem. Physical ability was perceived as being more important than appearance by the participants in this study, considering their preconception of an association between declining health, abilities, and older age. Involvement in physical activity appears to play a significant role in the perception of the women's own aging. Although physical attractiveness is a desirable outcome, the most important positive impact of the group exercise was related to increased social belonging and well-being, physical abilities, and capabilities. Thus implications for practice suggests that an intensive group training contributes to the opinion that an aging body is not necessarily a barrier to positive and successful aging.

AB - INTRODUCTION: Elderly patients make up a significant proportion of patients with metastatic breast cancer. With several options available in the metastatic setting for hormone positive breast cancer, these patients require an individualized approach to decision-making that considers multiple factors beyond performance status and chronologic age. Areas covered: The authors review the literature on endocrine monotherapy and combinations for hormone positive metastatic breast cancer, with specific commentary on the efficacy and toxicity for elderly patients. The authors describe the role of comprehensive geriatric assessment (CGA) and highlight the considerations for the use of bone modifying agents, and HER2-targeted therapy for hormone positive/HER2+ patients. Expert opinion: Evidence for elderly patients is largely based on subgroup analyses, which should be interpreted with caution. Nonetheless, elderly patients with metastatic hormone receptor positive breast cancer appear to derive similar benefit from treatments as younger patients. Similarly, for most drugs, these patients have no significant worsening of toxicity compared to younger patients. In addition to tumor biology, patient values and information from the CGA should be used to guide treatment decisions.

PMID- 29601250 TI - Examining Trends in Cost and Clinical Benefit of Novel Anticancer Drugs Over Time. AB - PURPOSE: The purpose of this study was to determine if clinical benefits of novel anticancer drugs, measured by the ASCO Value Framework and European Society of Medical Oncology (ESMO) Magnitude of Clinical Benefit Scale, have increased over time in parallel with increasing costs. METHODS: Anticancer drugs from phase III randomized controlled trials cited for clinical efficacy evidence in drug approvals between January 2006 to December 2015 were identified and scored using both frameworks. For each drug, the monthly price and incremental anticancer drug costs were calculated. Relationships between cost and year of approval were examined using generalized linear regressions models. Ordinary least square models were used to evaluate relationships between ASCO and ESMO scores and year of approval. Spearman correlation coefficients between costs and clinical benefit scores were calculated. RESULTS: In total, 42 randomized controlled trials were included. Both monthly prices and incremental anticancer drug costs were significantly associated with year of approval and showed an average annual increase of 9% and 21%, respectively. The predicted mean incremental anticancer drug cost increased from $30,447 in 2006 to $161,141 in 2015 (greater than five fold increase). Both ASCO and ESMO scores were not statistically associated with year of approval or correlated with monthly prices or incremental anticancer drug costs. CONCLUSION: Over the past decade, costs of novel oncology drugs have increased, while clinical benefits of these medications have not experienced a proportional positive change. The incremental anticancer drug costs have increased at a much greater rate than monthly prices, indicating that the increase in anticancer drug costs may be higher than commonly reported. PMID- 29601251 TI - The effect of a wearable soft-robotic glove on motor function and functional performance of older adults. AB - Reduced grip strength, resulting in difficulties in performing daily activities, is a common problem in the population of older adults. Newly developed soft robotic devices have the potential to support older adults with reduced grip in daily activities. The objective of this study was to evaluate the direct, assistive effect of grip support from the wearable, soft-robotic ironHand glove. In total, 65 older adults with self-reported decline of hand function resulting from various disorders participated in this cross-sectional study. They performed various hand function tests with and without the glove during a single session. At the end, usability was scored. Participants were able to produce more pinch strength with the glove compared to without glove (p <= 0.001) and usability was rated very positively. However, this was not reflected in improved functional performance with the glove, as measured with timed tasks (p < 0.001). Furthermore, no correlation was found between baseline handgrip strength and changes in performance (between without and with glove) of all assessments (rho <= 0.137, p >= 0.288). Further design adaptations are desired and more research is needed to investigate if performance with the glove can improve, when taking quality of task performance into account, or when applying a longer acquaintance period with the glove. PMID- 29601252 TI - Chemical Contaminants in Raw and Pasteurized Human Milk. AB - BACKGROUND: Environmental contaminants ranging from legacy chemicals like p,p' dichlorodiphenyltrichloroethane (DDT) to emerging chemicals like phthalates are ubiquitous. Research aims/questions: This research aims to examine the presence and co-occurrence of contaminants in human milk and effects of pasteurization on human milk chemical contaminants. METHODS: We analyzed human milk donated by 21 women to a milk bank for 23 chemicals, including the persistent organic pollutants (POPs) polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), dichlorodiphenyltrichloroethane (DDT), and dichlorodiphenyldichloroethylene (DDE) isomers that are known to sequester in adipose tissue, along with the current-use and nonpersistent pesticides chlorpyrifos and permethrin, phthalates, and bisphenol A (BPA). Human milk was analyzed raw and pasteurized for these chemicals using gas chromatography-tandem mass spectrometry for the POPs and high-performance liquid chromatography-tandem mass spectrometry for non-POPs. RESULTS: Within the different chemical classes, PBDE47, PCB153, ppDDE, and MEHHP (phthalate metabolite) had the highest median concentrations and were observed in all samples. We also observed chlorpyrifos and BPA in all samples and permethrin in 90% of the samples tested. Only two chemicals, chlorpyrifos and permethrin, were susceptible to substantial degradation from pasteurization, a standard method for processing donated human milk. CONCLUSION: We detected 19 of 23 chemicals in all of our prepasteurized milk and 18 of 23 chemicals in all of our pasteurized milk. Pasteurization did not affect the presence of most of the chemicals. Future research should continue to explore human milk for potential chemical contamination and as a means to surveil exposures among women and children.

AB - A novel compound structurally similar to tadalafil was found in a dietary supplement by adulterants screening test and isolated by column chromatography. After analysis by accurate mass, nuclear magnetic resonance (NMR) and X-ray, the structure of this novel tadalafil analogue was determined as (5R, 16R)-5-(1,3 benzodioxol-5-yl)-2- (3-ethypentan-3-yl)-15,16-dihydro(1H-imidazo[1,5 a]pyrido)[3,4-b]indol-1,3-dion.

AB - This open-label, multicenter extension study (NCT02451514) assessed persistence of Neisseria meningitidis serogroups ABCWY antibodies 4 years after primary vaccination. Adolescents and young adults who previously received 2 doses of MenABCWY+OMV (Group III), 1 dose of MenACWY-CRM (Group VI), or newly-recruited vaccine-naive participants (Group VII) were administered 1 (Group III) or 2 doses (Groups VI and VII) of MenABCWY+OMV, 1 month apart. Immunogenicity was assessed by human serum bactericidal assay (hSBA). Safety and reactogenicity were also evaluated. Percentages of participants with hSBA titers >=8 (serogroups ACWY), >=5 (serogroup B) and hSBA geometric mean titers (GMTs) were evaluated in all 129 enrolled participants (Group III: 33; Group VI: 46; Group VII: 50). Anti-ACWY antibody concentrations waned over 4 years post-vaccination, but remained above pre-vaccination concentrations. Similarly, levels of antibodies against serogroup B test strains also waned over 4 years post-vaccination, but remained above pre vaccination concentrations for some strains. MenABCWY+OMV booster induced a robust anamnestic anti-ACWY response in Group III and VI and a good response against serogroup B test strains (>=82%) in Group III. In serogroup B-naive participants (Groups VI and VII), anti-B responses to 2 doses of MenABCWY+OMV were less homogenous and lower than in Group III. MenABCWY+OMV was reactogenic, but well-tolerated. No safety concerns were identified. These findings indicate that although antibodies against N. meningitidis serogroups ABCWY waned over 4 years post-vaccination, exposure to a MenABCWY+OMV booster dose elicits an anamnestic response in adolescents previously exposed to the same or another multivalent meningococcal vaccine. PMID- 29601253 TI - The current status, challenges, and future developments of new tuberculosis vaccines. AB - Mycobacterium tuberculosis complex causes tuberculosis (TB), one of the top 10 causes of death worldwide. TB results in more fatalities than multi-drug resistant (MDR) HIV strain related coinfection. Vaccines play a key role in the prevention and control of infectious diseases. Unfortunately, the only licensed preventive vaccine against TB, bacilli Calmette-Guerin (BCG), is ineffective for prevention of pulmonary TB in adults. Therefore, it is very important to develop novel vaccines for TB prevention and control. This literature review provides an overview of the innate and adaptive immune response during M. tuberculosis infection, and presents current developments and challenges to novel TB vaccines. A comprehensive understanding of vaccines in preclinical and clinical studies provides extensive insight for the development of safer and more efficient vaccines, and may inspire new ideas for TB prevention and treatment.

AB - Capsaicinoids are pungent components in hot peppers, which have been detected in waste cooking oil. However, trace analysis of capsaicinoids in edible and crude vegetable oils is a challenging task due to the complex matrix. In this study, a simple liquid-liquid extraction and solid phase extraction (SPE) coupled with RP UPLC-ESI-MS/MS method was developed for the quantification of capsaicinoids in edible and crude vegetable oils to screen the adulteration with waste cooking oil. This method was used to simultaneously determine 3 capsaicinoids (capsaicin, dihydrocapsaicin, and nordihydrocapsaicin) with capsaicin-d3, and dihydrocapsaicin-d3 as internal standards. This method allows the complete analysis of a sample in only an hour, even including sample preparation and chromatographic separation. The linear range of 3 capsaicinoids ranged between 0.5 and 40 ug/kg. The limit of detection (LOD) and limit of quantification (LOQ) for capsaicinoids were calculated as 0.15 and 0.5 ug/kg, respectively. Quantitative recoveries ranging from 92.9% to 105% were obtained by the analysis of spiked oil. The relative standard deviations were less than 5% (n = 6). The established method can potentially overcome the interference of triacylglycerols and fatty acids in edible and crude vegetable oils, and have been successfully applied to analyse real oil samples. This method provided a rapid and reliable method for the detection of adulteration of vegetable oils with waste cooking oils. PMID- 29601259 TI - Analysis of the dose-sparing effect of adjuvanted Sabin-inactivated poliovirus vaccine (sIPV). AB - Sabin-based inactivated poliovirus vaccine(sIPV) is gradually replacing live attenuated oral polio vaccine(OPV). Sabin-inactivated poliovirus vaccine(sIPV) has played a vital role in reducing economic burden of poliomyelitis and maintaining appropriate antibody levels in the population. However, due to its high cost and limited manufacturing capacity, sIPV cannot reach its full potential for global poliovirus eradication in developing countries. Therefore, to address this situation, we designed this study to evaluate the dose-sparing effects of AS03, CpG oligodeoxynucleotides (CpG-ODN) and polyinosinic:polycytidylic acid (PolyI:C) admixed with sIPV in rats. Our results showed that a combination of 1/4-dose sIPV adjuvanted with AS03 or AS03 with BW006 provides a seroconversion rate similar to that of full-dose sIPV without adjuvant and that, this rate is 5-fold higher than that of 1/4-dose sIPV without adjuvant after the first immunization. The combination of AS03 or AS03 with BW006 as an adjuvant effectively reduced sIPV dose by at least 4-fold and induced both humoral and cellular immune responses. Therefore, our study revealed that the combination of AS03 or AS03 with BW006 is a promising adjuvant for sIPV development. PMID- 29601260 TI - Sensitive enzyme immunoassay for screening methandienone in dietary supplements. AB - Methandienone is a synthetic exogenous steroid which, like other anabolic steroids, is strictly regulated in many countries. In recent years, increasing numbers have been detected of illegal additions into dietary supplements of methandienone and other anabolic androgenic steroids (AAS). In this work, a competitive indirect enzyme-linked immunosorbent assay (ELISA) has been constructed for the detection of methandienone using an antiserum against methandienone. Under optimal experimental conditions, the ELISA achieved a limit of detection of 0.04 +/- 0.01 ug.g-1. The obtained intra- and inter-day coefficients of variation were less than 8%. The developed ELISA was applied in the analysis of real dietary supplement samples. To minimise the effect of the sample matrix, the sample extracts were simply diluted before addition into the immunoassay. The achieved recovery values were around 100%. Results obtained from the ELISA correlated well, both in terms of accuracy and precision, with those obtained by UHPLC-MS/MS (reference method). The presented ELISA could be successfully applied for the simple screening of dietary supplements. PMID- 29601262 TI - Appendiceal Pinworms.

AB - OBJECTIVE: Individuals looking to improve their health or weight status often use nonnutritive sweeteners (NNS), yet NNS consumption has been associated with increased risk factors for metabolic syndrome (MetS). Most studies examining NNS only assess total intake using diet soda as a proxy for NNS consumption, without distinguishing potential risks associated with individual sweeteners. The objective of this cross-sectional investigation was to identify whether there were associations between NNS consumption (total or individual) and risk factors for MetS in adults (n = 125) from Southwest Virginia. METHODS: Participants provided three 24-hour dietary recalls and blood pressure, waist circumference, fasting glucose, triglycerides, and high-density lipoprotein cholesterol were assessed. Linear regression models, adjusted for age, sex, caloric intake, dietary quality, and physical activity, examined associations between total and individual types of NNS with MetS and MetS risk factors. RESULTS: Sixty-three participants were classified as NNS consumers and eighteen met the criteria for MetS. While no significant associations between MetS and NNS consumption were found, waist circumference was positively associated with total NNS, saccharin, sucralose, and acesulfame potassium, and both fasting glucose and triglyceride values were positively associated with total NNS and aspartame consumption. CONCLUSION: While these cross-sectional data are consistent with previous work implicating NNS in development of MetS, additional research using randomized controlled trials is needed to clarify whether and how NNS in general or specific NNS might contribute to risk factors for MetS. This trial was registered at clinicaltrials.gov (NCT03364452). PMID- 29601265 TI - Coronary Artery Fistulas: Pathophysiology, Imaging Findings, and Management. AB - Coronary artery fistulas (CAFs) are abnormal communications of coronary arteries whereby venous circuits bypass the normal capillaries within the myocardium. CAFs are rare, and most affected patients are asymptomatic. However, these fistulas are the most common coronary artery anomalies that can alter coronary hemodynamic parameters. Although most CAFs are asymptomatic in young patients, symptoms and complications become more frequent with increasing age. CAFs are characterized by variable clinical manifestations that are based on the size, origin, and drainage site of the fistula. In symptomatic cases, surgical ligation or percutaneous transcatheter closure is often recommended. Although CAFs historically have been evaluated with conventional invasive angiography, electrocardiographically gated cardiac computed tomographic (CT) angiography has emerged as the noninvasive alternative modality of choice owing to the high spatial and temporal resolution and short acquisition time. Furthermore, three-dimensional volume-rendered CT angiograms facilitate accurate assessment of the complex anatomy of CAFs, including their origin, drainage site, and complexity and the number and size of fistulous tracts. Knowledge of these characteristics is crucial for therapeutic planning. Radiologists must be aware of the pathophysiology, clinical manifestations, and characteristic CT angiographic findings of CAFs; appropriate CT angiographic protocols for evaluation of various CAFs; and the role of CT angiography in preprocedural planning and follow-up.

AB - Von Hippel-Lindau syndrome (VHL) is an autosomal-dominant hereditary tumor disease that arises owing to germline mutations in the VHL gene, located on the short arm of chromosome 3. Patients with VHL may develop multiple benign and malignant tumors involving various organ systems, including retinal hemangioblastomas (HBs), central nervous system (CNS) HBs, endolymphatic sac tumors, pancreatic neuroendocrine tumors, pancreatic cystadenomas, pancreatic cysts, clear cell renal cell carcinomas, renal cysts, pheochromocytomas, paragangliomas, and epididymal and broad ligament cystadenomas. The VHL/hypoxia inducible factor pathway is believed to play a key role in the pathogenesis of VHL-related tumors. The diagnosis of VHL can be made clinically when the characteristic clinical history and findings have manifested, such as the presence of two or more CNS HBs. Genetic testing for heterozygous germline VHL mutation may also be used to confirm the diagnosis of VHL. Imaging plays an important role in the diagnosis and surveillance of patients with VHL. Familiarity with the clinical and imaging manifestations of the various VHL related tumors is important for early detection and guiding appropriate management. The purpose of this article is to discuss the molecular cytogenetics and clinical manifestations of VHL, review the characteristic multimodality imaging features of the various VHL-related tumors affecting multiple organ systems, and discuss the latest advances in management of VHL, including current recommendations for surveillance and screening.

PMID- 29601267 TI - Performance of purified grape pomace as a fining agent to reduce the levels of some contaminants from wine. AB - The quality of red wine depends on the absence of compounds which may affect its safety and/or stability such as ochratoxin A, biogenic amines and some metals and trace compounds. The presence of ochratoxin A in musts and wines is due to fungal contamination of the grapes and has been classified as a possible human carcinogen. Biogenic amines are formed by the microbiological decarboxylation of the corresponding amino acid precursors during the fermentation or ageing and storage, and, at high concentrations, they may induce adverse reactions in sensitive people. Trace elements may have both a nutritional and a toxic effect on health, but also can cause turbidity and stability problems. Their presence is affected mainly by natural factors such as soil mineral content and direct contact with tank surfaces and metallic tubing during winemaking. One of the best options to remove these compounds when present in excess in wine is fining. However, some fining agents commonly used may themselves present problems related with their allergenic properties or with their propensity to increase the protein content, which can cause turbidity problems. In an attempt to avoid such these problems, purified grape pomace was tested as a fining alternative since it has been seen to have a high capacity to reduce the astringency, turbidity and also the ochratoxin A content. The main aim of this work, therefore, was to study if this material can limit the presence of ochratoxin A, biogenic amines and metals and some trace elements in a Monastrell red wine, thus increasing the value and safety of this product. PMID- 29601268 TI - Influence of a Concurrent Exercise Training Program During Pregnancy on Colostrum and Mature Human Milk Inflammatory Markers: Findings From the GESTAFIT Project. AB - BACKGROUND: Although exercise reduces systemic inflammation, information regarding its influence on human milk is scarce or inexistent. Research Aim: The aim of this study was to investigate the influence of an exercise intervention during pregnancy on colostrum and mature human milk inflammatory markers. METHODS: The authors conducted a pseudorandomized controlled trial. The exercise group followed a concurrent aerobic and strength training, three 60-minutes sessions per week, from the 17th gestational week until delivery. For the specific aims of this study, only women able to produce enough milk were included for data analyses, resulting in 24 exercise and 23 control women. Colostrum and mature human milk proinflammatory and anti-inflammatory cytokines (fractalkine, interleukin [IL]-1beta, IL-6, IL-8, IL-10, interferon [IFN]-gamma, and tumor necrosis factor [TNF]-alpha) were measured using Luminex xMAP technology. RESULTS: The mothers who followed the exercise program had 36% lower IL-8 and 27% lower TNF-alpha concentrations in their colostrum than those in the control group ( p < .05 and p < .01, respectively). The colostrum from mothers who followed the exercise program also presented borderline significant 22% lower IL-6 ( p < .100). The mature milk from mothers who followed the exercise program had 30% greater fractalkine ( p = .05) and borderline significant 20% higher IL-10 ( p = .100). The exercise intervention did not affect IFN-gamma concentrations. CONCLUSIONS: This concurrent exercise program promoted a less proinflammatory profile in human milk, especially in colostrum. Moreover, it might increase mature human milk fractalkine, which could induce a greater neurodevelopment and neuroprotection in the newborn. This trial was registered at ClinicalTrials.gov (NCT02582567) on October 20, 2015. PMID- 29601270 TI - Do Fitness Apps Need Text Reminders? An Experiment Testing Goal-Setting Text Message Reminders to Promote Self-Monitoring. AB - Fitness tracking apps have the potential to change unhealthy lifestyles, but users' lack of compliance is an issue. The current intervention examined the effectiveness of using goal-setting theory-based text message reminders to promote tracking activities on fitness apps. We conducted a 2-week experiment with pre- and post-tests with young adults (n = 50). Participants were randomly assigned to two groups-a goal-setting text message reminder group and a generic text message reminder group. Participants were asked to use a fitness tracking app to log physical activity and diet for the duration of the study. Participants who received goal-setting reminders logged significantly more physical activities than those who only received generic reminders. Further, participants who received goal-setting reminders liked the messages and showed significantly increased self-efficacy, awareness of personal goals, motivation, and intention to use the app. The study shows that incorporating goal-setting theory-based text message reminders can be useful to boost user compliance with self-monitoring fitness apps by reinforcing users' personal goals and enhancing cognitive factors associated with health behavior change. PMID- 29601269 TI - Molecular Minimal Residual Disease in Acute Myeloid Leukemia. AB - BACKGROUND: Patients with acute myeloid leukemia (AML) often reach complete remission, but relapse rates remain high. Next-generation sequencing enables the detection of molecular minimal residual disease in virtually every patient, but its clinical value for the prediction of relapse has yet to be established. METHODS: We conducted a study involving patients 18 to 65 years of age who had newly diagnosed AML. Targeted next-generation sequencing was carried out at diagnosis and after induction therapy (during complete remission). End points were 4-year rates of relapse, relapse-free survival, and overall survival. RESULTS: At least one mutation was detected in 430 out of 482 patients (89.2%). Mutations persisted in 51.4% of those patients during complete remission and were present at various allele frequencies (range, 0.02 to 47%). The detection of persistent DTA mutations (i.e., mutations in DNMT3A, TET2, and ASXL1), which are often present in persons with age-related clonal hematopoiesis, was not correlated with an increased relapse rate. After the exclusion of persistent DTA mutations, the detection of molecular minimal residual disease was associated with a significantly higher relapse rate than no detection (55.4% vs. 31.9%; hazard ratio, 2.14; P<0.001), as well as with lower rates of relapse-free survival (36.6% vs. 58.1%; hazard ratio for relapse or death, 1.92; P<0.001) and overall survival (41.9% vs. 66.1%; hazard ratio for death, 2.06; P<0.001). Multivariate analysis confirmed that the persistence of non-DTA mutations during complete remission conferred significant independent prognostic value with respect to the rates of relapse (hazard ratio, 1.89; P<0.001), relapse-free survival (hazard ratio for relapse or death, 1.64; P=0.001), and overall survival (hazard ratio for death, 1.64; P=0.003). A comparison of sequencing with flow cytometry for the detection of residual disease showed that sequencing had significant additive prognostic value. CONCLUSIONS: Among patients with AML, the detection of molecular minimal residual disease during complete remission had significant independent prognostic value with respect to relapse and survival rates, but the detection of persistent mutations that are associated with clonal hematopoiesis did not have such prognostic value within a 4-year time frame.

PMID- 29601271 TI - The Importance of 'Likes': The Interplay of Message Framing, Source, and Social Endorsement on Credibility Perceptions of Health Information on Facebook. AB - Online sources not only permeate the information-seeking environment of the younger generation, but also have profound influence in shaping their beliefs and behaviors. In this landscape, examining the factors responsible for credibility perceptions of online information is fundamental, particularly for health-related information. Using a 2 (frames: gain vs. loss) * 2 (source: expert vs. non expert) * 2 (social endorsement: high vs. low) randomized between-subjects experimental design, this study examines the effect of health message framing and the moderating effects of social endorsement and source type on credibility perceptions of Facebook posts. Testing across two issues--physical activity and alcohol consumption--findings indicate that the gain-framed message was perceived as most credible. Additionally, significant three-way interactions suggest that social endorsement and source type affect the relationship between message framing and credibility perceptions. Specifically, the findings demonstrate that a gain-framed message from an expert source with high number of 'likes' is considered the most credible message. These findings have significant implications for information gathering from social media sources, such as the influence of 'likes' on health information. PMID- 29601272 TI - Unhealthy weight control behaviors among youth: Sex of sexual partner is linked to important differences. AB - Unhealthy weight control behaviors (UWCBs) have been decreasing for most youth over time, yet little is known whether these behaviors have changed for sexual minority (e.g., non-heterosexual) youth. This is important because many studies have found that sexual minorities report some of the highest rates of UWCBs. To determine whether or not these behaviors have changed over time, given the extreme changes in social contexts over the past two decades, we utilised three waves of the Minnesota Student Survey (N = 55,597, Mage = 17). In doing so, we report trends, disparities, and changes in disparities of UWCBs. Overall, the prevalence of UWCBs has declined from 1999 to 2010 for all youth, but there are alarming disparities by sex of sexual partner. We found that both- and same-sex partnered male youth were more likely to fast, use diet pills, and vomit on purpose to lose weight compared to their opposite-sex partnered counterparts in all three survey years; specifically, both-sex partnered boys were up to 5.5* as likely to vomit on purpose compared to their opposite-sex partnered counterparts. Likewise, both-sex partnered girls were more likely to use diet pills and vomit on purpose to lose weight compared to opposite-sex partnered girls in all three survey years. Additionally, the disparity in fasting to lose weight widened for the same-sex partnered females compared to the opposite-sex partnered females from 1998 to 2004. This has implications for UWCB interventions and preventions targeted specifically towards sexual minorities.

AB - Along with health development in general terms, women's involvement in health programs can be effective in raising their self-confidence and their health promotion. This study was carried out to unveil the barriers to and challenges of the health volunteers and to present the solutions to its promotion using active women participants' experiences and the authorities of the program. The study was carried out using qualitative method along with content analysis in city of Tabriz East-Azerbaijan province, Iran. Data collection was conducted utilizing semistructured individual interviews and focus group discussions with the participation of 29 health volunteers and responsible authorities. The participants were selected using purposive sampling with maximum variation. Data analysis implemented conventional content analysis using MAXODA. Barriers to and challenges of health volunteers were generally categorized into four main themes including volunteers and trainers' inadequate capabilities, inadequate acceptance of the volunteers, restrictive social norms, and organizational problems. It seems that interaction among health system, people, and health volunteers should be improved. Holding training programs about the activities of health volunteers at the society level leads into the better utilization of society sources in health programs. PMID- 29601274 TI - REVISITING THE SAFE PLACE:Method and Regulatory Aspects in Psychotherapy when Easing Allostatic Overload in Traumatized Patients. AB - Safe-place inductions are considered important altered states of consciousness (ASC) to be (re)installed during trauma-informed psychotherapy. Coregulation aimed at changing implicit relational knowing and increasing integration and coherence through relational work and hypnotic techniques is crucial, as clients' abilities to self-soothe and regulate have become seriously impaired. Thus, resource-oriented metaphors as inner strength imagery is advocated. Also, methods such as creative-arts therapy and neurofeedback will induce ASCs, as most methods used with complex traumatized clients, due to their high hypnotizability. When positive or soothing imagery or relationally held suggestions for changed attentional focus are added to both psychodynamic psychotherapy and CBT, a hetero hypnosis will be induced-a prerequisite for phase-specific trauma therapy aimed at changing inner schemas and scripts. PMID- 29601275 TI - EFFECTS OF CONVERSATIONAL HYPNOSIS ON RELATIVE PARASYMPATHETIC TONE AND PATIENT COMFORT DURING AXILLARY BRACHIAL PLEXUS BLOCKS FOR AMBULATORY UPPER LIMB SURGERY:A Quasiexperimental Pilot Study. AB - This two-center quasiexperimental pilot study was to determine the effect of conversational hypnosis on patient comfort and parasympathetic tone, which may represent a quantitative measure of hypnotic depth, during regional anesthesia. The patients received conversational hypnosis in one center and oral premedication in the other. The patients' subjective comfort (0-10 rating scale) and objective parasympathetic tone, as assessed by the Analgesia/Nociception Index (ANI), were measured before and after regional anesthesia. The parasympathetic tone and comfort scores evidenced a significantly greater increase in the hypnosis patients than in controls. These findings suggest that using conversational hypnosis during regional anesthesia may be followed by a subjective increase in patient comfort and an objective increase in parasympathetic tone, monitored by ANI.

AB - Presurgical stress and its negative influences on postsurgical recovery and pain are well documented in the medical literature. Hence, the reduction of stress is advisable. The present study aimed to reduce stress using a hypnotic-based animated video. Thirty children aged 3 to 16 years hospitalized for ambulatory surgery for undescended testes or umbilical/inguinal hernia were recruited for the study. They watched the video 1 time prior to surgery in the presence of their parents and reported their anxiety and pain pre- and postvideo watching on a visual analogue scale. The results show a statistically significant reduction in both anxiety and pain.

PMID- 29601278 TI - The Effect of Hypnosis on Adherence to Antituberculosis Drugs Using the Health Belief Model. AB - An RCT on the efficacy of hypnosis in improving adherence to antituberculosis treatment using the Health Belief Model (HBM). Sixty study subjects were sampled at random from tuberculosis patients who visited the Center for Pulmonary Community Health in Solo, Indonesia. Hypnotherapy with posthypnotic suggestions was delivered once a week over 6 months. The data on pretested 7 HBM constructs were analyzed using t test and path analysis. Hypnotherapy had a positive effect on perceived susceptibility, seriousness, threat, benefit, and self-efficacy. It indirectly had a positive effect on adherence. Hypnotherapy had a negative effect on perceived barrier. This study supports the hypothesis that hypnotherapy effectively improves adherence to tuberculosis treatment, by enhancing health related perception and beliefs in the HBM. PMID- 29601281 TI - The feasibility of goal attainment scaling to measure case resolution in elder abuse and neglect adult protective services intervention. AB - OBJECTIVES: This pilot study describes implementation procedures of goal attainment scaling (GAS) and examines the feasibility of using GAS to measure the multifarious intervention outcome of case resolution in elder mistreatment (EM) adult protective services (APS). METHODS: Substantiated EM victims (n = 27) were recruited prospectively from the State of Maine APS. An adapted GAS approach was implemented involving development of a pre-populated goal scale menu and web based GAS application. RESULTS: The GAS menu comprised 18 goals and corresponding scales spanning several domains of case resolution: social support, service access, health/functioning, enhancing independence, and protective measures. The overall GAS process had mean length 33.8 min per case. The mean GAS summary t score (54.3) aligned with theoretical expectations. DISCUSSION: Without a measure of case resolution, research cannot compare the effectiveness of different EM intervention models. Findings suggest that GAS is a feasible, client-centered strategy to measure the multifarious EM intervention case resolution outcome.

The authors tested behaviorally and with event-related potentials (ERP) if sequential learning (SL), the ability to learn statistical regularities, can be enhanced with PHS. Thirty adults were assessed with the Stanford Hypnotic Susceptibility Scale (Form C) and an auditory SL task. Before this task, half the sample received a PHS to enhance SL, and the other half received the same suggestion under normal waking state. Response times and ERPs indicated a strong effect of PHS. Compared to the control group, PHS inverted, attenuated, or left unaffected the response time SL effect in low, medium, and high hypnotizability participants, respectively. These results suggest that PHS cannot be used to enhance SL.

AB - This qualitative study examined the housing needs of grandparent caregivers and the youth in their care in New York State. Nine focus groups were conducted separately with grandparent caregivers (n = 46) and youth (n = 34), and interviews were conducted with key informants (n = 17) knowledgeable about housing and issues. Housing needs of greatest priority, contextual differences, and potential barriers to securing housing and social services were identified. Key themes indicated that housing challenges stem from four problem domains: the experience of poverty, which creates affordability challenges that trap grandparent caregivers and their grandchildren in unsuitable homes and unsafe neighborhoods; physical challenges of aging grandparents, which require specific housing accommodations; changes in family composition when taking in grandchildren, which necessitate moving out of prior accommodations or changing housing plans due to regulatory issues; and obstacles to obtaining needed benefits, including a lack of information, burdensome application processes, ineligibility, and a shortage of resources. These issues are discussed with implications for policy and practice. PMID- 29601286 TI - Implementing a college mental health program - an overview of the first twelve months. AB - OBJECTIVE: To evaluate the demographics and clinical utilization patterns among college students during the initial 12 months of a novel, multi-disciplinary, collaborative, college mental health program (CMHP). PARTICIPANTS: Undergraduate and graduate students receiving treatment at the CMHP from Jan-Dec 2015. METHODS: De-identified data was obtained via electronic health records for all students receiving care through the CMHP. RESULTS: 1.2 FTE clinical providers treated 278 undergraduate and graduate students during the year (65.1% < age 26, 53.6% female, 49.6% caucasian). There were 1822 CMHP outpatient visits, 318 other medical visits and 103 total emergency room (ER)/inpatient visits. Ten students were identified as high utilizers of ER/inpatient services, while charges to the CMHP totaled $470,157 and total charges to the Health System were $2,378,315. CONCLUSIONS: Students with complex psychiatric/medical co-morbidities received cost effective, convenient and integrative treatment. Over time, we hope to intervene earlier and decrease ER/inpatient visits. PMID- 29601287 TI - Sexual vs. Non-sexual trauma, sexual satisfaction and function, and mental health in female veterans. AB - Trauma in general, and sexual assault in particular, is associated with serious mental health and functional problems. The quality of sexual satisfaction/function may be particularly impacted by sexual assault, and such sexual problems may account for some of the broader mental health and functioning impairments in sexual assault survivors. Accordingly, we examined self-reports of sexual health and mental health in a sample of 255 female veterans in committed, monogamous relationships who provided data regarding sexual assault (n = 153) or nonsexual trauma (n = 102). Trauma type was not associated with differences in sexual function, but sexual trauma was associated with significantly lower sexual satisfaction, greater posttraumatic stress disorder (PTSD) and depressive symptoms, and higher suicidal ideation. Furthermore, the indirect effect of trauma type on all mental health outcomes was significant via sexual satisfaction but not via sexual function. Finally, trauma type moderated the association of sexual function with suicidality, such that the association was significantly positive in those with a history of sexual assault but nonsignificant in those with nonsexual trauma. These results suggest that (1) female veterans' experience of sexual assault is related to sexual satisfaction, which in turn is related to mental health outcomes, and (2) a history of sexual assault may increase the importance of sexual functioning with regard to suicidality. PMID- 29601288 TI - Emotional numbing symptoms partially mediate the association between exposure to potentially morally injurious experiences and sexual anxiety for male service members. AB - Service members (SMs) returning from deployment are at risk of a range of sexual problems, some of which are thought to be related to psychological issues that may arise during deployment or combat. The current study sought to examine whether exposure to potentially morally injurious events (PMIEs) was associated with sexual anxiety (SA) above and beyond combat exposure and whether any such association was mediated by post-traumatic stress disorder (PTSD) symptom clusters. These questions were tested using data from self-report surveys collected from 221 partnered male Army (Active Duty, National Guard, or Reserve) SMs at three separate time points. Findings showed that exposure to PMIEs was significantly related to greater SA, with transgressions by self and perceived betrayal demonstrating unique associations when controlling for all factors of PMIEs. Moreover, total exposure to PMIEs was associated with SA above and beyond general combat exposure. PTSD symptoms partially mediated the association between exposure to PMIEs and SA, with emotional numbing accounting for significant unique indirect effects after controlling for other PTSD symptom clusters. The findings suggest that exposure to PMIEs is associated with SA, even when accounting for either combat exposure or PTSD symptoms, emphasizing the importance of this issue in understanding post-deployment problems in sexual intimacy.

PMID- 29601290 TI - A comparison of risk factors for various forms of trauma in the lives of lesbian, gay, bisexual and heterosexual homeless youth. AB - Numerous homeless youth experience trauma prior to leaving home and while on the street. Bullying and trading sex (i.e. exchanging sexual favors for survival items such as food) are additional forms of trauma experienced by many homeless youth. Although lesbian, gay, and bisexual (LGB) homeless youth experience higher rates of child abuse compared to their heterosexual counterparts, there is a paucity of research comparing these two groups. As such, we compare whether difficulties finding items of necessity (e.g. food) and different forms of trauma including child sexual abuse, being bullied, trading sex, and street sexual victimization significantly differ for LGB and heterosexual homeless youth. Bivariate results reveal that LGB youth have more trouble finding shelter and are more likely to trade sex compared to heterosexual youth. Logistic regression results show that trading sex is correlated with street sexual victimization. In the second model, we find that being female, experiencing more child sexual abuse, and ever having traded sex are all positively linked with street sexual victimization. LGB youth are over-represented among homeless youth populations and are also more likely to trade sex; therefore, these young people need services that are widely accessible and specific to their needs. PMID- 29601291 TI - On hate crime victimization: Rates, types, and links with suicide risk among sexual orientation minority special interest group members. AB - Hate crimes remain pressing traumatic events for sexual orientation minority adults. Previous literature documents patterns in which hate crime victimization is associated with elevated risk for poor mental health. The present paper held 2 aims to advance literature. First, we investigated the rates and types of hate crime victimization among sexual orientation minority adults. Second, adopting a mental health amplification risk model, we evaluated whether symptoms of depression, impulsivity, or post-traumatic stress exacerbated the hate crime victimization-suicide risk link. Participants were 521 adult sexual orientation minority-identifying members of the National Coalition for Sexual Freedom (i.e., a bondage and discipline, and sadomasochism-identifying sexuality special interest group). Participants completed demographic and mental health inventories via online administration. Results showed: (1) low rates of total lifetime hate crime victimization and (2) higher rates of interpersonal violence compared to property crime victimization within the sample. Regression results showed: (1) independent positive main effects of all 3 mental health symptom categories with suicide risk; (2) an interaction pattern in which impulsivity was positively associated with suicide risk for non-victims; and (3) an interaction pattern in which post-traumatic stress was positively associated with suicide risk for hate crime victims and non-victims. Results are discussed concerning implications for trauma-informed mental healthcare, mental health amplification models, and hate crime and suicide prevention policies. PMID- 29601292 TI - Treatment experiences among LGBT veterans with discrimination-based trauma exposure: A pilot study. AB - Past research suggests that rates of trauma exposure and Posttraumatic Stress Disorder (PTSD) are elevated among lesbian, gay, bisexual, and transgender (LGBT) veterans compared to heterosexual and cisgender veterans. Given higher rates of trauma exposure and PTSD, and the culture associated with the Department of Defense's history of policies excluding LGBT people, it is important to understand if LGBT veterans are seeking PTSD treatment following discrimination based traumatic events, where they seek care, and if they are satisfied with treatment. This study aimed to describe the experiences of discrimination-based trauma-exposed LGBT veterans' (n = 47) experiences with PTSD treatment, including location of treatment (Veterans Health Administration [VHA] versus non-VHA) and satisfaction with care. The majority of veterans had received a PTSD diagnosis from a health-care provider in their lifetimes (78.72%, n = 37), and over half reported currently experiencing PTSD symptoms. Approximately 47% of LGBT veterans with discrimination-based trauma histories preferred to seek PTSD treatment exclusively at VHA (46.81%) or with a combination of VHA and non-VHA services (38.30%). Veterans who received PTSD treatment exclusively from VHA reported higher satisfaction ratings (7.44 on 0-9 scale) than veterans who received PTSD treatment exclusively from outside VHA (5.25 on 0-9 scale). For veterans who sought PTSD treatment at both VHA and non-VHA facilities, there were no significant differences regarding satisfaction ratings for their PTSD treatment in the two settings. Results are discussed in terms of VHA's continued efforts to establish equitable, patient-centered health care for all veterans and the importance of non-VHA facilities to recognize veteran identities. PMID- 29601293 TI - A resilience framework: Sexual health trajectories of youth with maltreatment histories. AB - There is a wealth of knowledge regarding negative sexual outcomes experienced by youth with childhood maltreatment (CM) histories, yet a dearth of research examines healthy sexual development among these youth. This gap exists despite evidence of resilience highlighting alternative and healthy physical, social, and psychological futures for youth who were abused. This study tested whether trajectories of resilience identified in studies of psychological functioning were applicable to sexual health. Using data from the first four waves of the National Longitudinal Study of Adolescent to Adult Health, latent class growth analysis was conducted among individuals with histories of CM (N = 1,437). On average, participants were 15, 16, 21, and 28 years old, respectively, by waves of data collection. About half of the sample was female (55%), the majority were White (66%), and a sizeable portion had experienced multiple forms of CM prior to Wave I (38%). Controlling for CM severity, three distinct sexual health trajectory classes were identified: resilient, survival, and improving, which were differentiated by age and biological sex. Older participants' sexual health was more likely to diminish over time, girls were more likely to show gains in sexual health over time, and significant differences in levels of sexual behaviors between the classes were only present during adolescence. Findings support the need for increased attention on the potential for sexual health despite experiences of CM, and highlight the applicability of resilience theory to youth sexuality.

PMID- 29601296 TI - Identification of facilitators and barriers to residents' use of a clinical reasoning tool. AB - BACKGROUND: While there is some experimental evidence to support the use of cognitive forcing strategies to reduce diagnostic error in residents, the potential usability of such strategies in the clinical setting has not been explored. We sought to test the effect of a clinical reasoning tool on diagnostic accuracy and to obtain feedback on its usability and acceptability. METHODS: We conducted a randomized behavioral experiment testing the effect of this tool on diagnostic accuracy on written cases among post-graduate 3 (PGY-3) residents at a single internal medical residency program in 2014. Residents completed written clinical cases in a proctored setting with and without prompts to use the tool. The tool encouraged reflection on concordant and discordant aspects of each case. We used random effects regression to assess the effect of the tool on diagnostic accuracy of the independent case sets, controlling for case complexity. We then conducted audiotaped structured focus group debriefing sessions and reviewed the tapes for facilitators and barriers to use of the tool. RESULTS: Of 51 eligible PGY-3 residents, 34 (67%) participated in the study. The average diagnostic accuracy increased from 52% to 60% with the tool, a difference that just met the test for statistical significance in adjusted analyses (p=0.05). Residents reported that the tool was generally acceptable and understandable but did not recognize its utility for use with simple cases, suggesting the presence of overconfidence bias. CONCLUSIONS: A clinical reasoning tool improved residents' diagnostic accuracy on written cases. Overconfidence bias is a potential barrier to its use in the clinical setting. PMID- 29601297 TI - Laboratory error reporting rates can change significantly with year-over-year examination. AB - BACKGROUND: Incident reporting systems are useful tools to raise awareness of patient safety issues associated with healthcare error, including errors associated with the medical laboratory. METHODS: Previously, we presented the analysis of data compiled by the British Columbia Patient Safety & Learning System over a 3-year period. A second comparable set was collected and analyzed to determine if reported error rates would tend to remain stable or change. RESULTS: Compared to the original set, the second set presented changes that were both materially and statistically significant. Overall, the total number of reports increased by 297% with substantial changes between the pre-examination, examination and post-examination phases (chi2: 993.925, DF=20; p<0.00001). While the rate of change for pre-examination (clerical and collection) errors were not significantly different than the total year results, the rate of change for reporting examination errors rose by 998%. While the exact reason for dramatic change is not clear, possible explanations are provided. CONCLUSIONS: Longitudinal error rate tracking is a useful approach to monitor for laboratory quality improvement. PMID- 29601298 TI - Sepsis as a model for improving diagnosis. AB - Diagnostic safety could theoretically be improved by high-level interventions, such as improving clinical reasoning or eliminating system-related defects in care, or by focusing more specifically on a single problem or disease. In this review, we consider how the timely diagnosis of sepsis has evolved and improved as an example of the disease-focused approach. This progress has involved clarifying and revising the definitions of sepsis, efforts to raise awareness, faster and more reliable laboratory tests and a host of practice-level improvements based on health services research findings and recommendations. We conclude that this multi-faceted approach incorporating elements of the 'learning health system' model has improved the early recognition and treatment of sepsis, and propose that this model could be productively applied to improve timely diagnosis in other time-sensitive conditions. PMID- 29601299 TI - Becoming a teacher of clinical reasoning. AB - Diagnostic reasoning is one of the most challenging and rewarding aspects of clinical practice. As a result, facility in teaching diagnostic reasoning is a core necessity for all medical educators. Clinician educators' limited understanding of the diagnostic process and how expertise is developed may result in lost opportunities in nurturing the diagnostic abilities of themselves and their learners. In this perspective, the authors describe their journeys as clinician educators searching for a coherent means of teaching diagnostic reasoning. They discuss the initial appeal and immediate applicability of dual process theory and cognitive biases to their own clinical experiences and those of their trainees, followed by the eventual and somewhat belated recognition of the importance of context specificity. They conclude that there are no quick fixes in guiding learners to expertise of diagnostic reasoning, but rather the development of these abilities is best viewed as a long, somewhat frustrating, but always interesting journey. The role of the teacher of clinical reasoning is to guide the learners on this journey, recognizing true mastery may not be attained, but should remain a goal for teacher and learner alike. PMID- 29601300 TI - Cannabinoids in health and disease: pharmacological potential in metabolic syndrome and neuroinflammation. AB - The use of different natural and/or synthetic preparations of Cannabis sativa is associated with therapeutic strategies for many diseases. Indeed, thanks to the widespread diffusion of the cannabinoidergic system in the brain and in the peripheral districts, its stimulation, or inhibition, regulates many pathophysiological phenomena. In particular, central activation of the cannabinoidergic system modulates the limbic and mesolimbic response which leads to food craving. Moreover, cannabinoid agonists are able to reduce inflammatory response. In this review a brief history of cannabinoids and the protagonists of the endocannabinoidergic system, i.e. synthesis and degradation enzymes and main receptors, will be described. Furthermore, the pharmacological effects of cannabinoids will be outlined. An overview of the involvement of the endocannabinoidergic system in neuroinflammatory and metabolic pathologies will be made. Finally, particular attention will also be given to the new pharmacological entities acting on the two main receptors, cannabinoid receptor type 1 (CB1) and cannabinoid receptor type 2 (CB2), with particular focus on the neuroinflammatory and metabolic mechanisms involved. PMID- 29601301 TI - On "A mutual information estimator with exponentially decaying bias" by Zhang and Zheng. AB - Zhang, Z. and Zheng, L. (2015): "A mutual information estimator with exponentially decaying bias," Stat. Appl. Genet. Mol. Biol., 14, 243-252, proposed a nonparametric estimator of mutual information developed in entropic perspective, and demonstrated that it has much smaller bias than the plugin estimator yet with the same asymptotic normality under certain conditions. However it is incorrectly suggested in their article that the asymptotic normality could be used for testing independence between two random elements on a joint alphabet. When two random elements are independent, the asymptotic distribution of $?sqrt{n}$n-normed estimator degenerates and therefore the claimed normality does not hold. This article complements Zhang and Zheng by establishing a new chi-square test using the same entropic statistics for mutual information being zero. The three examples in Zhang and Zheng are re-worked using the new test. The results turn out to be much more sensible and further illustrate the advantage of the entropic perspective in statistical inference on alphabets. More specifically in Example 2, when a positive mutual information is known to exist, the new test detects it but the log likelihood ratio test fails to do so. PMID- 29601302 TI - Drug error in paediatric anaesthesia: current status and where to go now. AB - PURPOSE OF REVIEW: Medication errors in paediatric anaesthesia and the perioperative setting continue to occur despite widespread recognition of the problem and published advice for reduction of this predicament at international, national, local and individual levels. Current literature was reviewed to ascertain drug error rates and to appraise causes and proposed solutions to reduce these errors. RECENT FINDINGS: The medication error incidence remains high. There is documentation of reduction through identification of causes with consequent education and application of safety analytics and quality improvement programs in anaesthesia departments. Children remain at higher risk than adults because of additional complexities such as drug dose calculations, increased susceptibility to some adverse effects and changes associated with growth and maturation. Major improvements are best made through institutional system changes rather than a commitment to do better on the part of each practitioner. SUMMARY: Medication errors in paediatric anaesthesia represent an important risk to children and most are avoidable. There is now an understanding of the genesis of adverse drug events and this understanding should facilitate the implementation of known effective countermeasures. An institution-wide commitment and strategy are the basis for a worthwhile and sustained improvement in medication safety. PMID- 29601303 TI - The opioid epidemic and pregnancy: implications for anesthetic care. AB - PURPOSE OF REVIEW: This review summarizes evolving knowledge regarding adverse maternal, fetal, and neonatal effects of opioid exposure during pregnancy, and current treatment options for opioid use disorder (OUD). Maternal and fetal implications of maternal opioid maintenance with methadone and buprenorphine are described. Finally, acute and chronic pain management strategies in opioid tolerant parturients are reviewed. RECENT FINDINGS: Opioid use among parturients has risen dramatically, with opioid use during pregnancy as high as 20%. Of women with chronic pain, most continue to take opioids during pregnancy. Medication assisted therapy with methadone or buprenorphine is currently the standard for treatment of opiate use disorder. Buprenorphine has unique pharmacologic properties that account for its preference over methadone. It has also been shown to produce more favorable neonatal outcomes compared with methadone. Increased clearance and volume of distribution associated with pregnancy require adjustment of dosing regimens of both medications. Multimodal adjuncts can be important alternatives for treatment of pain in opioid-tolerant parturients. SUMMARY: The dramatic rise in OUD in pregnancy has had staggering socioeconomic consequences, carrying with it profound maternal and fetal health problems. Medication-assisted treatment utilizing either methadone, or more commonly buprenorphine, is considered the standard of care for OUD during pregnancy. Peripartum pain management for opioid-tolerant patients is challenging and requires consideration for regional anesthesia along with multimodal pharmacotherapy. PMID- 29601304 TI - Episodic syndromes of childhood associated with migraine. AB - PURPOSE OF REVIEW: This review covers recent advances in our understanding of episodic syndromes that may be associated with migraine in children and adolescents, as well as what is known about the treatment of these disorders. RECENT FINDINGS: The episodic syndromes include benign paroxysmal torticollis, benign paroxysmal vertigo, abdominal migraine, and cyclic vomiting syndrome. Infant colic, or excessive crying in an otherwise healthy and well fed infant, may also fit into this category and is included in the appendix section of the most recent edition of the International Classification of Headache Disorders. SUMMARY: Episodic syndromes are considered to be early life expressions of migraine in the developing brain. Additional research is needed to determine, which acute and preventive treatments are the most effective in managing these disorders. PMID- 29601305 TI - Noninvasive neuromodulation in migraine and cluster headache. AB - PURPOSE OF REVIEW: The purpose of this narrative review is to provide an overview of the currently available noninvasive neuromodulation devices for the treatment of migraine and cluster headache. RECENT FINDINGS: Over the last decade, several noninvasive devices have undergone development and clinical trials to evaluate efficacy and safety. Based on this body of work, single-pulse transcranial magnetic stimulation, transcutaneous supraorbital neurostimulation, and noninvasive vagal nerve stimulation devices have been cleared by the United States Food and Drug Administration and are available for clinical use for the treatment of primary headache disorders. SUMMARY: Overall, these novel noninvasive devices appear to be safe, well tolerated, and have demonstrated promising results in clinical trials in both migraine and cluster headache. This narrative review will provide a summary and update of the proposed mechanisms of action, evidence, safety, and future directions of various currently available modalities of noninvasive neuromodulation for the treatment of migraine and cluster headache. PMID- 29601306 TI - Evidence-based guidelines in lower urinary tract symptoms secondary to benign prostatic hyperplasia and variation in care. AB - PURPOSE OF REVIEW: Guidelines have been developed to assist physicians in the diagnosis and management of patients with lower urinary tract symptoms. These guidelines vary in the level of evidence used and the strength of their recommendations. With variations in guidelines, multiple variations in clinical practice may also been seen. RECENT FINDINGS: Although examinations of physician compliance with benign prostatic hyperplasia (BPH) guidelines date back to the 1980s, researchers have become more interested in closer examination of guideline compliance. Furthermore, guidelines themselves are becoming more robust documents, with the American Urological Association and European Association of Urology guidelines updated in 2014 and 2015, respectively. This review examines both the evidence base behind these BPH guidelines and the variations in clinical care related to the guidelines. SUMMARY: Despite over 40 years of study, variations continue to occur in the work up and treatment of men with BPH. With the proliferation of medications and surgical procedures available for symptomatic lower urinary tract symptoms (LUTS) due to BPH, we will continue to see this variation in care. Our current guidelines can help mitigate this variation by providing a baseline set of assessments and algorithms for routine patients. However, only through continued refinement will the guidelines meet their full potential. The prior review shows how the evidence base is limited for the diagnostic work up for LUTS, provides limited information on comparative effectiveness of therapies in LUTS and BPH, and has not led to consistency between guidelines. PMID- 29601307 TI - Applying American Society of Addiction Medicine Performance Measures in Commercial Health Insurance and Services Data. AB - OBJECTIVES: ASAM's Standards of Care for the Addiction Specialist established appropriate care for the treatment of substance use disorders. ASAM identified three high priority performance measures for specification and testing for feasibility in various systems using administrative claims: use of pharmacotherapy for alcohol use disorder (AUD); use of pharmacotherapy for opioid use disorder (OUD); and continuity of care after withdrawal management services. This study adds to the initial testing of these measures in the Veteran's Health Administration (VHA) by testing the feasibility of specifications in commercial insurance data (Cigna). METHODS: Using 2014 and 2015 administrative data, the proportion of individuals with an AUD or OUD diagnosis each year who filled prescriptions or were dispensed appropriate FDA-approved pharmacotherapy. For withdrawal management follow up, the proportion with an outpatient encounter within seven days was calculated. The sensitivity of specifications was also tested. RESULTS: Rates of pharmacotherapy for AUD ranged from 6.2% to 7.6% (depending on year and specification details), and rates for OUD pharmacotherapy were 25.0% to 29.7%. Seven-day follow up rate after withdrawal management in an outpatient setting was 20.5%, and an additional 39.7% in an inpatient or residential setting. CONCLUSIONS: Application of ASAM specifications is feasible in commercial administrative data. Because of varying system needs and payment practices across health systems, measures may require adjustment for different settings. Moving forward, important focus will be on the continued refinement of these measures with the new ICD-10 coding systems, new formulations of current medications, and new payment approaches such as bundled payment.

PMID- 29601309 TI - Anatomical and procedural predictors of pulmonary vein stenosis in the setting of second-generation cryoballoon ablation. AB - AIMS: Pulmonary vein stenosis (PVS) is a well recognized complication as a consequence of pulmonary vein isolation. In the current study, we sought to analyze potential anatomical and intraprocedural predictors of PVS during second generation cryoballoon ablation, particularly focusing on the impact of freeze duration and number of cryoapplications. METHODS: Fifty-four patients who underwent cryoballoon ablation for atrial fibrillation were included retrospectively in this study. All patients underwent cardiac-enhanced multidetector computed tomography both before and after the ablation. The exclusion criteria were any contraindications for the procedure, including the presence of an intracavitary thrombus, uncontrolled heart failure and contraindications to general anesthesia. RESULTS: Mild (25-50%) PVS was only detected in one vein (0.4%) and neither moderate (50-75%) nor severe (>75%) PVS were found. Twenty-five pulmonary veins (12%) exhibited slight narrowing of the diameter (less than 25%). In the univariate analysis, a longer duration of cryoapplication and a larger pulmonary vein ostium preprocedure diameter and area were independently associated with pulmonary vein narrowing [odds ratio (OR): 1.004; confidence interval (CI): 1.001-1.008, P = 0.016; OR: 1.250, CI: 1.090 1.434, P = 0.001 and OR: 1.006; CI: 1.002-1.011, P = 0.006] respectively. CONCLUSION: Longer duration of cryoablation, an increased number of applications per vein and larger pulmonary vein ostia are associated with a higher risk of pulmonary vein diameter and area reduction. These findings might suggest to lower the dosing to a single and shorter application if isolation is attained, to reduce the possibility of future pulmonary vein narrowing. PMID- 29601310 TI - Ticagrelor-related late-onset dyspnea as cause of emergency department visit: a 3 year outpatient study. AB - INTRODUCTION: The aim of the current study was to define the rate of emergency department visits for late-onset dyspnea in acute coronary syndrome patients treated with ticagrelor. METHODS: We conducted a population-based study on about 850 000 residents of Florence metropolitan area, by using data from healthcare records. RESULTS: Between 2012 and 2014, 1073 subjects in Florence metropolitan area had at least one prescription of ticagrelor. Two-hundred and thirty-four patients were diagnosed with 'respiratory system or other chest symptoms' or 'other diseases of lung', and among them we identified 20 subjects with ticagrelor-related late-onset dyspnea. These, and the 979 nonevent subjects (receiving ticagrelor but not developing dyspnea), contributed to 413 person years overall. The dyspnea rate was 4.84 per 100 person-years (95% confidence interval: 3.12-7.51). CONCLUSION: Late-onset dyspnea rate is notably lower than early-onset one; nevertheless prescribing clinicians should be aware that about one in 20 outpatients with a stabilized ticagrelor treatment might develop a dyspnea leading to an emergency department visit, and they should consider ticagrelor replacement only in patients who cannot tolerate dyspnea. PMID- 29601312 TI - Myeloid cells regulate plasma LDL-cholesterol levels. AB - PURPOSE OF REVIEW: Leukocytosis, elevated blood leukocyte levels, is associated with enhanced cardiovascular risk in humans. Hematopoietic stem and progenitor cells (HSPCs) drive leukocyte production in a process called hematopoiesis, which mainly occurs in the bone marrow, and under certain conditions also in other organs such as the spleen. Cholesterol accumulation in HSPCs enhances hematopoiesis, increasing levels of blood monocytes that infiltrate into atherosclerotic plaques. Although HSPC proliferation and monocytosis enhance atherogenesis in several studies, concomitant decreases in LDL-cholesterol levels have also been reported, associated with anti-atherogenic effects. This review focuses on the link between HSPC proliferation, leukocytosis, plasma LDL cholesterol levels, and atherogenesis. RECENT FINDINGS: Recent studies have shown that an acute infection enhances cholesterol accumulation in HSPCs, driving HSPC proliferation, and leading to the expansion of myeloid cells (monocytes, neutrophils, and macrophages). Enhanced hematopoiesis is associated with low plasma LDL-cholesterol levels in animal models and humans, probably because of the increased number of myeloid cells that take up LDL-cholesterol. Despite low plasma LDL-cholesterol levels, specific patient populations with enhanced hematopoiesis show increased cardiovascular risk. SUMMARY: Enhanced hematopoiesis and monocytosis may accelerate atherogenesis. Studies on these processes may lead to the identification of new therapeutic targets for cardiovascular diseases. PMID- 29601311 TI - Classical and alternative roles for autophagy in lipid metabolism. AB - PURPOSE OF REVIEW: Intracellular lipid metabolism is a complex interplay of exogenous lipid handling, trafficking, storage, lipolysis, and export. Recent work has implicated the cellular degradative process called autophagy in several aspects of lipid metabolism. We will discuss both the classical and novel roles of autophagy and the autophagic machinery in this setting. RECENT FINDINGS: The delivery of lipid droplets to lysosomes for hydrolysis, named lipophagy, was the first described functional role for autophagy in lipid metabolism. The molecular machinery and regulation of this selective form of macroautophagy is beginning to be discovered and has the potential to shed enormous light on intracellular lipolysis. Yet, the autophagic machinery appears to also be coopted for alternative roles that include interaction with cytosolic lipolysis pathways, supply and expansion of lipid droplets, and lipoprotein trafficking. Additionally, lesser studied forms of autophagy called microautophagy and chaperone-mediated autophagy have distinct roles in lipid handling that also intersect with classical macroautophagy. The integration of current knowledge in these areas into a holistic understanding of intracellular lipid metabolism will be a goal of this review. SUMMARY: As the field of autophagy has evolved and expanded to include functional roles in various aspects of cellular degradation, so has its role in intracellular lipid metabolism. Understanding the mechanisms underlying these classical and alternative roles of autophagy will not only enhance our knowledge in lipid biology but also provide new avenues of translation to human lipid disorders. PMID- 29601313 TI - Increasing the Number of Medical Emergency Calls Does Not Improve Hospital Mortality. AB - OBJECTIVES: Medical emergency teams were established to rescue patients experiencing clinical deterioration thus preventing cardiac arrest and unexpected hospital mortality. Although hospitals are encouraged to increase emergency calling rates to improve in-hospital mortality, there are increasing concerns about the impact these calls have on the workload of the teams and the skill levels on the general wards. We set out to examine the relationship between emergency calling rates and adjusted in-hospital mortality. DESIGN: Retrospective analysis of prospectively collected patient and emergency call data. SETTING: Tertiary, metropolitan, and regional hospitals in the State of Victoria, Australia. PATIENTS: Consecutive patients discharged from 1) St Vincent's Hospital Melbourne from January 2008 to June 2016 and 2) 15 Victorian hospitals from July 2010 to June 2015. MEASUREMENTS AND MAIN RESULTS: We studied 441,029 patients from St Vincent's Hospital Melbourne. Median age was 61.0 years (interquartile range, 45-74 yr), 57.2% were men, and 0.70% died; monthly emergency calling rates varied between 9.21 and 30.69 (median 18.4) per 1,000 discharges. In-hospital mortality adjusted for age, gender, emergency status, same day admission, year of discharge, and Charlson Comorbidity Index was not reduced by higher calling rates in the month of discharge (odds ratio, 1.019; 95% CI, 1.008-1.031). We then examined 3,339,789 discharges from 15 Victorian hospitals with median age 61 years (interquartile range, 43-74 yr), 51.4% men, and hospital mortality 0.83% where yearly emergency calling rates varied from 18.46 to 33.40 (median, 25.75) per 1,000 discharges. Again, adjusted mortality was not reduced by higher calling rates in the year of discharge (odds ratio, 1.003; 95% CI, 1.001-1.006). CONCLUSIONS: With adjustment for patient factors, illness, and comorbidities, increased emergency calling rates were not associated with reduced in-hospital mortality. Efforts to increase calling rates do not seem warranted. PMID- 29601314 TI - Diagnostic Accuracy of Chest Radiograph, and When Concomitantly Studied Lung Ultrasound, in Critically Ill Patients With Respiratory Symptoms: A Systematic Review and Meta-Analysis. AB - OBJECTIVES: Chest radiograph is considered the first-line diagnostic imaging modality for patients presenting with pulmonary symptoms in the ICU. In this meta analysis, we aim to evaluate the diagnostic accuracy of chest radiograph, and when concomitantly studied lung ultrasound, in comparison with the gold-standard CT for adult critically ill patients with respiratory symptoms. DATA SOURCES: PubMed, EMBASE, and Gray literature. STUDY SELECTION: Studies comparing chest radiograph, and if performed lung ultrasound, with CT for adult ICU patients with respiratory symptoms. DATA EXTRACTION: Quality was scored with Quality Assessment of Diagnostic Accuracy Studies-2, and study setting, test characteristics, and study design were extracted. DATA SYNTHESIS: In the meta-analysis, we included 10 full-text studies, including 543 patients, and found that chest radiograph has an overall sensitivity of 49% (95% CI, 40-58%) and specificity of 92% (86-95%). In seven studies, where also lung ultrasound was studied, lung ultrasound had an overall sensitivity of 95% (92-96%) and specificity of 94% (90-97%). Substantial heterogeneity was found. A planned subgroup analysis for individual pathologies was performed. The results of four abstract-only studies, included in the systematic review, were considered unlikely to significantly influence results of our meta-analysis. Study limitations were that most studies were of low power combined with methodological limitations. CONCLUSIONS: This meta-analysis demonstrates that chest radiograph has a low sensitivity and reasonable specificity compared with CT for detecting lung pathology in critically ill patients. The studies also investigating lung ultrasound, showed lung ultrasound to be clearly superior to chest radiograph in terms of sensitivity with similar specificity, thereby opting to be the first-line diagnostic tool in these patients. PMID- 29601315 TI - Revisited: A Systematic Review of Therapeutic Hypothermia for Adult Patients Following Traumatic Brain Injury. AB - OBJECTIVES: Therapeutic hypothermia has been of topical interest for many years and with the publication of two international, multicenter randomized controlled trials, the evidence base now needs updating. The aim of this systematic review of randomized controlled trials is to assess the efficacy of therapeutic hypothermia in adult traumatic brain injury focusing on mortality, poor outcomes, and new pneumonia. DATA SOURCES: The following databases were searched from January 1, 2011, to January 26, 2018: Cochrane Central Register of Controlled Trial, MEDLINE, PubMed, and EMBASE. STUDY SELECTION: Only foreign articles published in the English language were included. Only articles that were randomized controlled trials investigating adult traumatic brain injury sustained following an acute, closed head injury were included. Two authors independently assessed at each stage. DATA EXTRACTION: Quality was assessed using the Cochrane Collaboration's tool for assessing the risk of bias. All extracted data were combined using the Mantel-Haenszel estimator for pooled risk ratio with 95% CIs. p value of less than 0.05 was considered statistically significant. All statistical analyses were conducted using RevMan 5 (Cochrane Collaboration, Version 5.3, Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2014). DATA SYNTHESIS: Twenty-two studies with 2,346 patients are included. Randomized controlled trials with a low risk of bias show significantly more mortality in the therapeutic hypothermia group (risk ratio, 1.37; 95% CI, 1.04 1.79; p = 0.02), whereas randomized controlled trials with a high risk of bias show the opposite with a higher mortality in the control group (risk ratio, 0.70; 95% CI, 0.60-0.82; p < 0.00001). CONCLUSIONS: Overall, this review is in-keeping with the conclusions published by the most recent randomized controlled trials. High-quality studies show no significant difference in mortality, poor outcomes, or new pneumonia. In addition, this review shows a place for fever control in the management of traumatic brain injury.

PMID- 29601316 TI - Clinical Trial of the Potassium Channel Activator Diazoxide for Major Depressive Disorder Halted Due to Intolerability. AB - BACKGROUND: Some glutamatergic modulators have demonstrated rapid and relatively sustained antidepressant properties in patients with major depressive disorder. Because the potassium channel activator diazoxide increases glutamate uptake via potassium channel activation, we hypothesized that it might exert antidepressant effects by increasing the removal of glutamate from the synaptic cleft, thereby reducing excessive glutamate transmission. METHODS: This randomized, double blind, placebo-controlled, crossover, single-site inpatient clinical study was conducted at the National Institute of Mental Health to assess the efficacy and safety of a 3-week course of diazoxide (200-400 mg daily, twice a day) versus a 3 week course of placebo in 6 participants with treatment-refractory major depressive disorder. The primary clinical outcome measure was change in Montgomery-Asberg Depression Rating Scale score from baseline to posttreatment. Quantitative insulin sensitivity check index, as well as concomitant imaging measures (electroencephalography, proton magnetic resonance spectroscopy, magnetoencephalography), were used as potential surrogate markers of target (KATP channel) engagement. RESULTS: The study was halted due to severe adverse effects. Given the small sample size, statistical evaluation of the effect of diazoxide on Montgomery-Asberg Depression Rating Scale scores or the imaging measures was not pursued. Visual inspection of the quantitative insulin sensitivity check index test revealed no evidence of target engagement. CONCLUSIONS: Although the results are negative, they are an important addition to the literature in this rapidly changing field.

AB - PURPOSE OF REVIEW: Esophageal manometry has shown its usefulness to estimate transpulmonary pressure, that is lung stress, and the intensity of spontaneous effort in patients with acute respiratory distress syndrome. However, clinical uptake of esophageal manometry in ICU is still low. Thus, the purpose of review is to describe technical tips to adequately measure esophageal pressure at the bedside, and then update the most important clinical applications of esophageal manometry in ICU. RECENT FINDINGS: Each esophageal balloon has its own nonstressed volume and it should be calibrated properly to measure pleural pressure accurately: transpulmonary pressure calculated on absolute esophageal pressure reflects values in the lung regions adjacent to the esophageal balloon (i.e. dependent to middle lung). Inspiratory transpulmonary pressure calculated from airway plateau pressure and the chest wall to respiratory system elastance ratio reasonably reflects lung stress in the nondependent 'baby' lung, at highest risk of hyperinflation. Also esophageal pressure can be used to detect and minimize patient self-inflicted lung injury. SUMMARY: Esophageal manometry is not a complicated technique. There is a large potential to improve clinical outcome in patients with acute respiratory distress syndrome, acting as an early detector of risk of lung injury from mechanical ventilation and vigorous spontaneous effort. PMID- 29601321 TI - Predicting adverse hemodynamic events in critically ill patients. AB - PURPOSE OF REVIEW: The art of predicting future hemodynamic instability in the critically ill has rapidly become a science with the advent of advanced analytical processed based on computer-driven machine learning techniques. How these methods have progressed beyond severity scoring systems to interface with decision-support is summarized. RECENT FINDINGS: Data mining of large multidimensional clinical time-series databases using a variety of machine learning tools has led to our ability to identify alert artifact and filter it from bedside alarms, display real-time risk stratification at the bedside to aid in clinical decision-making and predict the subsequent development of cardiorespiratory insufficiency hours before these events occur. This fast evolving filed is primarily limited by linkage of high-quality granular to physiologic rationale across heterogeneous clinical care domains. SUMMARY: Using advanced analytic tools to glean knowledge from clinical data streams is rapidly becoming a reality whose clinical impact potential is great. PMID- 29601323 TI - Early-phase Innate Immune Suppression in Murine Severe Sepsis Is Restored with Systemic Interferon-beta. AB - BACKGROUND: Sepsis is a leading cause of death in the intensive care unit. Immune modulatory therapy targeting sepsis-associated proinflammatory responses has not shown survival benefit. Here, the authors evaluated innate immunity at the early stage of murine mild or severe peritoneal sepsis induced by cecal ligation and puncture, and the effect of systemic interferon-beta, a potent inflammatory mediator, on severe sepsis as well as its mechanism of action. METHODS: Mild and severe sepsis was induced in C57BL/6 mice by cecal ligation and puncture with 22- and 18-gauge needles for puncture, respectively. Interferon-beta (700 U/g) was subcutaneously administered either before or 12 h after cecal ligation and puncture for the severe sepsis group. RESULTS: Severe sepsis resulted in significantly lower 6-day survival rates than mild sepsis (n = 48, 25% vs. n = 11, 81.8%, P = 0.002), significantly less phagocytic capacity of peritoneal exudate cells, and lower CXC chemokine receptor-2 expression on circulating neutrophils at 24 h after cecal ligation and puncture. Interferon-beta administration 12 h after cecal ligation and puncture associated with significantly improved survival (n = 34, 52.9%, P = 0.017) increased the number and function of peritoneal exudate cells, peritoneal/systemic inflammatory cytokine/chemokine concentrations, and CXC chemokine receptor-2 on neutrophils, compared with the severe sepsis controls. However, those responses were not observed in the prophylactic interferon-beta group (n = 24). Interferon-beta increased lipopolysaccharide-induced interleukin-6 messenger RNA/protein expression of lipopolysaccharide-tolerant murine peritoneal macrophages, which was not observed in nontolerant cells. CONCLUSIONS: In severe sepsis, immune suppression occurs within 24 h and is associated with worse mortality. Interferon beta given after the onset of peritonitis restores impaired innate immunity in vivo and in vitro. PMID- 29601322 TI - Peripherally Acting MU-Opioid Receptor Agonists Attenuate Ongoing Pain-associated Behavior and Spontaneous Neuronal Activity after Nerve Injury in Rats. AB - BACKGROUND: Ongoing neuropathic pain is difficult to treat. The authors examined whether dermorphin [D-Arg2, Lys4] (1-4) amide, a peripherally acting u-opioid receptor agonist, attenuates ongoing pain-associated manifestations after nerve injury in rats and mice. METHODS: Using conditioned place preference assay, the authors tested whether animals show a preference to the environment associated with drug treatment. Wide-dynamic range and dorsal root ganglion neuronal activities were measured by electrophysiology recording and calcium imaging. RESULTS: Nerve-injured animals stayed longer in dermorphin [D-Arg2, Lys4] (1-4) amide-paired chamber after conditioning than during preconditioning (rats: 402.4 +/- 61.3 vs. 322.1 +/- 45.0 s, 10 mg/kg, n = 9, P = 0.009; mice: 437.8 +/- 59.4 vs. 351.3 +/- 95.9 s, 2 mg/kg, n = 8, P = 0.047). Topical ganglionic application of dermorphin [D-Arg2, Lys4] (1-4) amide (5 MUM, 1 MUl, n = 5) reduced the numbers of small-diameter dorsal root ganglion neurons that showed spontaneous activity (1.1 +/- 0.4 vs. 1.5 +/- 0.3, P = 0.044) and that were activated by test stimulation (15.5 +/- 5.5 vs. 28.2 +/- 8.2, P = 0.009) after injury. In neuropathic rats, dermorphin [D-Arg2, Lys4] (1-4) amide (10 mg/kg, n = 8) decreased spontaneous firing rates in wide-dynamic range neurons to 53.2 +/- 46.6% of predrug level, and methylnaltrexone (5 mg/kg, n = 9) blocked dermorphin [D-Arg2, Lys4] (1-4) amide-induced place preference and inhibition of wide dynamic range neurons. Dermorphin [D-Arg2, Lys4] (1-4) amide increased paw withdrawal threshold (17.5 +/- 2.2 g) from baseline (3.5 +/- 0.7 g, 10 mg/kg, n = 8, P = 0.002) in nerve-injured rats, but the effect diminished after repeated administrations. CONCLUSIONS: Peripherally acting MU-opioids may attenuate ongoing pain-related behavior and its neurophysiologic correlates. Yet, repeated administrations cause antiallodynic tolerance. PMID- 29601324 TI - Neisseria gonorrhoeae vaccine development: hope on the horizon? AB - PURPOSE OF REVIEW: Neisseria gonorrhoeae is one of the most common causes of sexually transmitted infections, with an estimated more than 100 million cases of gonorrhea each year worldwide. N. gonorrhoeae has gained recent increasing attention because of the alarming rise in incidence and the widespread emergence of multidrug-resistant gonococcal strains. Vaccine development is one area of renewed interest. Herein, we review the recent advances in this area. RECENT FINDINGS: Vaccine development for N. gonorrhoeae has been problematic, but recent progress in the field has provided new hope that a gonococcal vaccine may be feasible. Several new vaccine antigens have been characterized in various models of infection. Furthermore, the first potential vaccine-induced protection against gonorrhea in humans has been reported, with decreased rates of gonorrhea described among individuals vaccinated with the Neisseria meningitidis serogroup B vaccine, MeNZB. SUMMARY: As antibiotic resistance continues to increase, vaccine development for N. gonorrhoeae becomes more urgent. The MeNZB vaccine is shown to have efficacy, albeit relatively low, against N. gonorrhoeae. This finding has the potential to reinvigorate research in the field of gonococcal vaccine development and will guide future studies of the antigens and mechanism(s) required for protection against gonococcal infection. PMID- 29601325 TI - Group A Streptococcus infections in children: from virulence to clinical management. AB - PURPOSE OF REVIEW: Recent findings have open new perspectives on group A Streptococcus (GAS) virulence understanding with special focus on the carrier stage and new hopes for an efficient vaccine against this important pathogen. RECENT FINDINGS: Understanding of carriage state, transmission and role of virulence factors in invasive infections have been recently active research fields questioning the link between carriage and infections and highlighting the potential to prevent invasive diseases. New roles for already well known virulence factors, such as Streptolysin O, M protein or NAD(+)-glycohydrolase have been discovered. Immunological studies have also shown diversity in both clinical and immunological responses toward various GAS antigens raising questions, and hopes, for the development of an efficient global vaccine candidate. SUMMARY: A greater understanding of GAS virulence strategies, and their associated clinical manifestations, may be obtained by shifting our research scope toward virulence determinant interactions and cooperation rather than focusing on individual virulence factor or specific strain characterization only. PMID- 29601326 TI - Human adenovirus infections: update and consideration of mechanisms of viral persistence. AB - PURPOSE OF REVIEW: To provide an update on recent studies of human adenoviral (HAdV) infections and to explore the mechanisms of viral persistence and the role of persistent infection in disseminated disease in immunocompromised patients. RECENT FINDINGS: Human adenoviruses continue to be a problem in ophthalmology clinics and to cause periodic, limited, global outbreaks of respiratory disease. Ad14p1 remains in worldwide circulation and continues to result in miniepidemics of severe respiratory infections. New variants of Ad4 and Ad7 have emerged in both the United States and Asia. The severity of Ad4 infections in outbreaks appears to depend more on preexisting conditions in patients than on genetically determined, viral virulence factors, in contrast to limited evidence of Ad7 mutations that may convey increased viral pathogenesis. Reactivation of persistent adenovirus infection appears to be the primary source of disseminated infections in immunocompromised patients. New studies suggest that establishment of persistent infection and reactivation are related to variations in interferon mediated control of viral replication. SUMMARY: Innate immune responses can create a state of adenoviral persistence, and repression of these host defenses can result in reactivation and dissemination of infection. A better definition of the molecular mechanisms of immune-mediated control of viral replication might lead to new strategies for treatment of HAdV reactivation and dissemination. PMID- 29601327 TI - Peripartum cardiomyopathy: approach to management. AB - PURPOSE OF REVIEW: To provide recommendations for the diagnosis and management of patients with peripartum cardiomyopathy (PPCM). RECENT FINDINGS: PPCM is pregnancy-associated myocardial disease that occurs during pregnancy or postpartum and is characterized by the development of heart failure due to marked left ventricular (LV) systolic dysfunction. The disease is relatively uncommon, but its incidence is increasing, and it remains an important cause of cardiac related maternal morbidity and mortality in previously healthy young women. With early diagnosis and treatment, the majority of the patients demonstrate recovery. SUMMARY: The review provides information on the clinical presentation, prognosis and contemporary management of PPCM as well as the approach to subsequent pregnancies, labor and delivery and long-term psychological consequences of the disease. PMID- 29601328 TI - Statin loading in cardiovascular surgery: never too early to treat. AB - PURPOSE OF REVIEW: The effects of statin loading before, during or after vascular interventions on cardiovascular and renal outcomes are discussed. Furthermore, the selection of optimal statin type and dose, according to current evidence or guidelines, is considered. The importance of treating statin intolerance and avoiding statin discontinuation is also discussed. RECENT FINDINGS: Statin loading has been shown to beneficially affect cardiovascular outcomes, total mortality and/or contrast-induced acute kidney injury, in patients undergoing vascular procedures such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), carotid endarterectomy (CEA), carotid artery stenting, endovascular aneurysm repair, open abdominal aortic aneurysms (AAA) repair and lower extremities vascular interventions. High-dose statin pretreatment is recommended for PCI and CABG according to current guidelines. Statin discontinuation should be avoided during acute cardiovascular events and vascular interventions; adequate measures should be implemented to overcome statin intolerance. SUMMARY: Statin loading is an important clinical issue in patients with cardiac and noncardiac vascular diseases, including carotid artery disease, peripheral artery disease and AAA, undergoing vascular interventions. Cardiologists and vascular surgeons should be aware of current evidence and implement guidelines in relation to statin loading, discontinuation and intolerance. PMID- 29601329 TI - HIV infection and lipids. AB - PURPOSE OF REVIEW: We comment on the role of dyslipidaemia in cardiovascular disease (CVD) in HIV-infected patients. We have discussed various risk factors, including traditional CVD risk factors, HIV-related risk factors and antiretroviral therapy (ART)-induced dyslipidaemia. RECENT FINDINGS: HIV-infected individuals are prone to lipid and lipoprotein abnormalities as a result of the infection itself and the effect of ART. The older drugs used for the treatment of HIV were associated with an increased risk of these abnormalities. New therapies used to treat HIV are lipid friendly. Calculating CVD risk in the HIV population is complex due to the infection itself and the ART-related factors. The advancement in ART has helped to increase the life expectancy of HIV patients. As a result, a growing number of patients die of non-HIV related complications such as CVD, hepatic and renal disease. Outcome studies with intervention for dyslipidaemia in HIV are underway. SUMMARY: The implications of the above findings suggest that all patients with HIV should undergo a CVD risk assessment before starting ART. Appropriate lipid-friendly ART regimen should be initiated along with intervention for associated CVD risk factors (e.g. lipids, hypertension and smoking). PMID- 29601330 TI - Introduction: Liquid Biopsies. PMID- 29601332 TI - Extracellular Vesicles in Cancer: Purpose and Promise. AB - Extracellular vesicles refer collectively to a heterogeneous group of membrane bound vesicles released from cells and loaded with bioactive proteins, nucleic acids, and lipids. The concept of extracellular vesicles has rapidly evolved from once being viewed as cellular debris to their recognition as packets of cellular information with considerable promise for clinical applications as biomarker platforms and therapeutic vehicles. These shed vesicles have emerged as critical mediators of intercellular communication in both local and distant microenvironments during normal physiological processes, as well as in orchestrating systemic pathophysiological events in disease. This mode of cellular crosstalk is particularly relevant to modulating the tumor microenvironment and orchestrating paths of least resistance during metastases. Here, we describe recent advances for the roles of extracellular vesicles in tumor progression and their potential as disease biomarkers. PMID- 29601331 TI - Implementing Liquid Biopsies in Clinical Trials: State of Affairs, Opportunities, and Challenges. AB - A primary goal of personalized medicine is to develop tumor-specific biomarkers to aid in treatment selection and to better evaluate response to targeted therapies. The assessment of circulating blood markers as surrogate real-time biopsies of disease status, termed liquid biopsies, has been under investigation. There are many different types of liquid biopsies each with different functionalities and limitations. These include tumor markers, circulating tumor cells, cell-free DNA, and extracellular vesicles including exosomes. Multiple clinical trials have evaluated liquid biopsies as prognostic biomarkers with positive results. Additional studies are underway to evaluate liquid biopsies as predictive biomarkers, pharmacodynamic biomarkers, and surrogate efficacy endpoints for treatment response evaluation. There are several challenges in and barriers to implementation of liquid biopsies into clinical trials and subsequently into routine clinical practice, which are addressed in this review. PMID- 29601334 TI - Liquid Biopsies and Cancer Immunotherapy. AB - Cancer immunotherapy has recently undergone rapid advances and has become an integral part of the treatment armamentarium in various malignancies. However, tissue-based biomarker development in this arena has been slow, and valid biomarker identification to guide immunotherapeutic management is desperately needed. "Liquid" or blood-based biopsies potentially offer more convenient and efficient means to judge the immune milieu of individual patients and identify who will benefit most from immunotherapy. The following review highlights the current literature regarding the application of liquid biopsies to cancer immunotherapy. PMID- 29601333 TI - Circulating Tumor Cells: Strategies for Capture, Analyses, and Propagation. AB - Circulating tumor cells (CTCs) play a central role in tumor dissemination and metastases, which are ultimately responsible for most cancer deaths. Technologies that allow for identification and enumeration of rare CTC from cancer patients' blood have already established CTC as an important clinical biomarker for cancer diagnosis and prognosis. Indeed, current efforts to robustly characterize CTC as well as the associated cells of the tumor microenvironment such as circulating cancer associated fibroblasts (cCAF), are poised to unmask key insights into the metastatic process. Ultimately, the clinical utility of CTC will be fully realized once CTC can be reliably cultured and proliferated as a biospecimen for precision management of cancer patients, and for discovery of novel therapeutics. In this review, we highlight the latest CTC capture and analyses technologies, and discuss in vitro strategies for culturing and propagating CTC. PMID- 29601335 TI - Mechanosensitive Ion Channels: TRPV4 and P2X7 in Disseminating Cancer Cells. AB - Cancer metastasis is the second leading cause of death in the United States. Despite its morbidity, metastasis is an inefficient process that few cells can survive. However, cancer cells can overcome these metastatic barriers via cellular responses to microenvironmental cues, such as through mechanotransduction. This review focuses on the mechanosensitive ion channels TRPV4 and P2X7, and their roles in metastasis, as both channels have been shown to significantly affect tumor cell dissemination. Upon activation, these channels help form tumor neovasculature, promote transendothelial migration, and increase cell motility. Conversely, they have also been linked to forms of cancer cell death dependent upon levels of activation, implying the complex functionality of mechanosensitive ion channels. Understanding the roles of TRPV4, P2X7 and other mechanosensitive ion channels in these processes may reveal new possible drug targets that modify channel function to reduce a tumor's metastatic potential. PMID- 29601336 TI - Molecular Profiling of Liquid Biopsy Samples for Precision Medicine. AB - In the context of oncology, liquid biopsies consist of harvesting cancer biomarkers, such as circulating tumor cells, tumor-derived cell-free DNA, and extracellular vesicles, from bodily fluids. These biomarkers provide a source of clinically actionable molecular information that can enable precision medicine. Herein, we review technologies for the molecular profiling of liquid biopsy markers with special emphasis on the analysis of low abundant markers from mixed populations. PMID- 29601338 TI - Evolving understanding of neonatal necrotizing enterocolitis. AB - PURPOSE OF REVIEW: Necrotizing enterocolitis (NEC) is a devastating disease that predominately affects premature neonates. The pathogenesis of NEC is multifactorial and poorly understood. Risk factors include low birth weight, formula-feeding, hypoxic/ischemic insults, and microbial dysbiosis. This review focuses on our current understanding of the diagnosis, management, and pathogenesis of NEC. RECENT FINDINGS: Recent findings identify specific mucosal cell types as potential therapeutic targets in NEC. Despite a broadly accepted view that bacterial colonization plays a key role in NEC, characteristics of bacterial populations associated with this disease remain elusive. The use of probiotics such as lactobacilli and bifidobacteria has been studied in numerous trials, but there is a lack of consensus regarding specific strains and dosing. Although growth factors found in breast milk such as epidermal growth factor and heparin-binding epidermal growth factor may be useful in disease prevention, developing new therapeutic interventions in NEC critically depends on better understanding of its pathogenesis. SUMMARY: NEC is a leading cause of morbidity and mortality in premature neonates. Recent data confirm that growth factors and certain bacteria may offer protection against NEC. Further studies are needed to better understand the complex pathogenesis of NEC. PMID- 29601337 TI - Future of Liquid Biopsies With Growing Technological and Bioinformatics Studies: Opportunities and Challenges in Discovering Tumor Heterogeneity With Single-Cell Level Analysis. AB - Liquid biopsy provides minimally invasive and readily obtainable access to tumor associated biological material in blood or other body fluids. These samples provide important insights into cancer biology, such as primary tumor heterogeneity; real-time tumor evolution; response to therapy, including immunotherapy; and mechanisms of cancer metastasis. Initial biological materials studied were circulating tumor cells and circulating nucleic acids, including circulating tumor DNA and microRNAs; more recently, studies have expanded to investigate extracellular vesicles, such as exosomes, microvesicles, and large oncosomes; tumor-derived circulating endothelial cells; and tumor-educated platelets. Even with an ongoing ambitious investment effort to develop liquid biopsy as an early cancer detection test in asymptomatic individuals, current challenges remain regarding how to access and analyze rare cells and tumor derived nucleic acids in cancer patients. Technologies and associated bioinformatics tools are continuously evolving to capture these rare materials in an unbiased manner and to analyze them with high confidence. After first presenting recent applications of liquid biopsy, this review discusses aspects affecting the field, including tumor heterogeneity, single-cell analyses, and associated computational tools that will shape the future of liquid biopsy, with resultant opportunities and challenges. PMID- 29601339 TI - The Role of the Electronic Medical Record in the Intensive Care Unit Nurse's Detection of Patient Deterioration: A Qualitative Study. AB - Failure to detect patient deterioration signals leads to longer stays in the hospital, worse functional outcomes, and higher hospital mortality rates. Surveillance, including ongoing acquisition, interpretation, and synthesis of patient data by the nurse, is essential for early risk detection. Electronic medical records promote accessibility and retrievability of patient data and can support patient surveillance. A secondary analysis was performed on interview data from 24 intensive care unit nurses, collected in a study that examined factors influencing nurse responses to alarms. Six themes describing nurses' use of electronic medical record information to understand the patients' norm and seven themes describing electronic medical record design issues were identified. Further work is needed on electronic medical record design to integrate documentation and information presentation with the nursing workflow. Organizations should involve bedside nurses in the design of handoff formats that provide key information common to all intensive care unit patient populations, as well as population-specific information. PMID- 29601340 TI - Missing Voices: Profile, Extent, and 12-Month Outcomes of Nonfatal Traumatic Brain Injury in Aboriginal and Non-Aboriginal Adults in Western Australia Using Linked Administrative Records. AB - OBJECTIVE: To investigate differences in the profile and outcomes between Aboriginal and non-Aboriginal Western Australians (WAs) hospitalized with traumatic brain injury (TBI). SETTING: WA hospitals. PARTICIPANTS: TBI cases aged 15 to 79 years surviving their first admission during 2002-2011. DESIGN: Patients identified from diagnostic codes and followed up for 12 months or more using WA wide person-based linked hospital and mortality data. MAIN MEASURES: Demographic profile, 5-year comorbidity history, injury mechanism, injury severity, 12-month readmission, and mortality risks. Determinants of 12-month readmission. RESULTS: Of 16 601 TBI survivors, 14% were Aboriginal. Aboriginal patients were more likely to be female, live remotely, and have comorbidities. The mechanism of injury was an assault in 57% of Aboriginal patients (vs 20%) and transport in 33% of non-Aboriginal patients (vs 17%), varying by remoteness. One in 10 Aboriginal TBI patients discharged themselves against medical advice. Crude 12-month readmission but not mortality risk was significantly higher in Aboriginal patients (48% vs 36%). The effect of age, sex, and injury mechanism on 12-month readmission was different for Aboriginal and non-Aboriginal patients. CONCLUSION: These findings suggest an urgent need for multisectoral primary prevention of TBI, as well as culturally secure and logistically appropriate medical and rehabilitation service delivery models to optimize outcomes. PMID- 29601341 TI - Informant Report of Financial Capacity for Individuals With Chronic Acquired Brain Injury: An Assessment of Informant Accuracy. AB - OBJECTIVE: Primarily, to investigate the association between informant report and objective performance on specific financial capacity (FC) tasks by adults with chronic, moderate to severe acquired brain injury, and to examine the nature of misestimates by the informants. DESIGN: Cross-sectional design. SETTING: A postacute, community-based rehabilitation center. PARTICIPANTS: Data were obtained from 22 chronic acquired brain injury (CABI) adults, mean age of 46.6 years (SD = 8.67), mean years of education of 13.45 years (SD = 2.15), with moderate to severe acquired brain injury (86% had traumatic brain injury), with a mean postinjury period of 17.14 years (SD = 9.5). Whereas the CABI adults completed the Financial Competence Assessment Inventory interview-a combination of self-report and performance-based assessment, 22 informants completed a specifically designed parallel version of the interview. RESULTS: Pearson correlations and 1-sample t tests based on the discrepancy scores between informant report and CABI group's performance were used. The CABI group's performance was not associated with its informant's perceptions. One-sample t tests revealed that informants both underestimated and overestimated CABI group's performance. CONCLUSIONS: Results indicate lack of correspondence between self- and informant ratings. Further investigation revealed that misestimations by informants occurred in contrary directions with CABI adults' performance being inaccurately rated. These findings raise critical issues related to assuming that the informant report can be used as a "gold standard" for collecting functional data related to financial management, and the idea that obtaining objective data on financial tasks may represent a more valid method of assessing financial competency in adults with brain injury. PMID- 29601342 TI - The Association of Rehospitalization With Participation 5 Years After Traumatic Brain Injury. AB - OBJECTIVE: To determine whether rehospitalization during the first 2 years after moderate to severe traumatic brain injury (TBI) is associated with poor participation at 5 years post-TBI, after controlling for demographic and severity factors. SETTING: TBI Model Systems Program. PARTICIPANTS: Community-dwelling individuals with TBI, 16 years or older (n = 1940). DESIGN: Retrospective data analysis of a multicenter prospective study. MAIN MEASURES: Participation Assessment with Recombined Tools-Objective (PART-O). RESULTS: After controlling for demographic and severity factors, a general linear model indicated that rehospitalization status (ie, never rehospitalized during years 1 and 2, rehospitalized either during year 1 or 2, or rehospitalized during both years 1 and 2) predicted less participation at 5 years post-TBI (P = .0353). The PART-O scores were in the hypothesized direction, with the lowest covariate-adjusted mean participation score found for the group with rehospitalizations during both years and the highest covariate-adjusted mean participation score found in the group with no rehospitalizations. Examining total number of rehospitalizations during years 1 and 2, rather than rehospitalization status, yielded analogous results (P = .0148). CONCLUSIONS: This study suggests that rehospitalization in the first 2 years after TBI is negatively associated with participation at 5 years after injury. Since participation is considered a key indicator of successful TBI rehabilitation, minimizing the need for rehospitalizations and promoting health in the community setting should be a priority of postacute care for individuals with TBI. PMID- 29601343 TI - A Preliminary Investigation of Accelerometer-Derived Sleep and Physical Activity Following Sport-Related Concussion. AB - OBJECTIVE: Describe changes in postconcussion activity levels and sleep throughout recovery in a sample of pediatric sport-related concussion (SRC) patients, and examine the predictive value of accelerometer-derived activity and sleep on subsequent clinical outcomes at a follow-up clinic visit. SETTING: Outpatient concussion clinic. PARTICIPANTS: Twenty athletes aged 12 to 19 years with diagnosed SRC. METHODS: Prospective study including visit 1 (<72 hours postinjury) and visit 2 (6-18 days postinjury). Linear regressions used to predict scores (ie, neurocognitive, vestibular/oculomotor) at visit 2 from accelerometer-derived data collected 0 to 6 days postinjury. Linear mixed models evaluated changes in activity and sleep across recovery. MAIN MEASURES: Symptom, neurocognitive, and vestibular/oculomotor scores; sleep and activity data (Actigraph GT3x+) RESULTS:: The maximum intensity of physical activity increased (P = .009) and time in bed decreased throughout recovery (P = .026). Several physical activity metrics from 0 to 6 days postinjury were predictive of worse vestibular/oculomotor scores at visit 2 (P < .05). Metrics indicative of poor sleep 0 to 6 days postinjury were associated with worse reaction time at visit 2 (P < .05). CONCLUSIONS: This exploratory study suggests physical activity and sleep change from the acute to subacute postinjury time period in adolescent SRC patients. In our small sample, excess physical activity and poor sleep the first week postinjury may be associated with worse outcomes at follow-up in the subacute stage of recovery. This study further supported the feasibility of research utilizing wearable technology in concussion patients, and future research in a large, diverse sample of concussion patients examined at concise time intervals postinjury is needed.

AB - OBJECTIVE: To examine the effects of a Web-based parenting intervention (I InTERACT), and an abbreviated version (Express), on caregiver depression, psychological distress, parenting stress, and parenting efficacy following pediatric traumatic brain injury (TBI). SETTING: Four children's hospitals and 1 general hospital in the United States. PARTICIPANTS: 148 caregivers of 113 children aged 3 to 9 years with a moderate to severe TBI. DESIGN: Multicenter randomized controlled trial. Participants were randomly assigned to I-InTERACT, Express, or an active control condition. Caregiver data were collected at baseline and postintervention (6 months later). INTERVENTION: I-InTERACT (10-14 sessions) and Express (7 sessions) combine live coaching of parenting skills and positive parenting strategies. MAIN MEASURES: Center for Epidemiologic Studies Depression Scale (CES-D); Global Severity Index of the Symptom Checklist-90-R (GSI), Parenting Stress Index (PSI), and Caregiver Self-Efficacy Scale (CSES). RESULTS: Analyses revealed no main effects of treatment on caregiver distress (GSI), parenting stress (PSI), or parenting efficacy (CSES). However, analyses examining baseline severity as a moderator found that caregivers with elevated levels of depression in I-InTERACT experienced significantly greater reductions in CES-D scores compared with caregivers in the active control condition. CONCLUSIONS: I-InTERACT reduced caregiver depression but no other facets of caregiver psychological functioning. Modifications to the treatment content may be necessary to reduce parenting stress and improve caregiver efficacy. PMID- 29601345 TI - Family Needs on an Inpatient Brain Injury Rehabilitation Unit: A Quantitative Assessment. AB - OBJECTIVE: To examine the needs of family members in an inpatient setting and factors predicting extent to which needs are perceived as met. SETTING: University health system inpatient rehabilitation unit. PARTICIPANTS: Adult survivors of traumatic brain injury and family members (n = 85). DESIGN: Prospective, cross-sectional. MAIN MEASURE: Family Needs Questionnaire-Revised (FNQ-R). RESULTS: Needs related to the Health Information subscale were most frequently rated as met, whereas needs related to the Instrumental Support and Emotional Support subscales were most frequently rated as unmet. Predictors related to the FNQ-R included family income, gender, and ethnicity. For 4 of 6 subscales, white family members were more likely to rate needs as unmet than minority members. For 3 subscales, females were more likely to rate needs as unmet than males. Greater household income was associated with fewer met needs for 2 subscales. CONCLUSIONS: The ranking of met and unmet needs in the present study was remarkably similar to previous studies within and outside the United States. Clinicians should not assume that families with relatively higher incomes will experience fewer unmet needs. Through structured assessment, clinicians can reveal perceived needs that might have otherwise been unrecognized and facilitate appropriate supports. Findings provide direction for inpatient program development. PMID- 29601346 TI - Low Bone Mineral Density in Elite Female Athletes With a History of Secondary Amenorrhea in Their Teens. AB - OBJECTIVE: To determine whether secondary amenorrhea during teenage years influences bone mineral density (BMD) in female athletes in their 20s. DESIGN: Original research. SETTING: Japan Institute of Sports Sciences. PARTICIPANTS: Two hundred ten elite female athletes older than 20 years were included in the study. MAIN OUTCOME MEASURES: Information on the participants' past (ie, during their teenage years) and current menstrual cycle, training time, history of stress fractures, and blood tests for hormones received was obtained. Bone mineral density of the lumbar spine was evaluated by dual-energy x-ray absorptiometry; low BMD was defined as a Z-score <=-1. We investigated the correlation factors for low BMD in athletes in their 20s by univariable and multivariable logistic regression analysis. RESULTS: A total of 39 (18.6%) female athletes had low BMD. Secondary amenorrhea in their teens [odds ratio (OR), 7.11, 95% confidence interval (CI), 2.38-21.24; P < 0.001] and present body mass index (BMI) (OR, 0.56, 95% CI, 0.42-0.73; P < 0.001) were independent correlation factors for low BMD in the multivariable logistic regression analysis. The average Z-score for those with secondary amenorrhea in their teens and 20s, secondary amenorrhea in their 20s only, and regular menstruation was -1.56 +/- 1.00, -0.45 +/- 1.21, and 0.82 +/- 1.11 g/cm, respectively. CONCLUSIONS: Secondary amenorrhea for at least 1 year during teenage years in female athletes and BMI at present was strongly associated with low BMD in their 20s. PMID- 29601347 TI - Test-Retest Reliability and the Effects of Exercise on the King-Devick Test. AB - OBJECTIVE: To determine the test-retest reliability and the influence of exercise on King-Devick (K-D) test performance. DESIGN: Crossover study design. SETTING: Controlled laboratory. PARTICIPANTS: Participants consisted of 63 (39 women and 24 men) healthy, recreationally active college students who were 21.0 + 1.5 years of age. INDEPENDENT VARIABLES: Participants completed the K-D test using a 2 week, test-retest interval. The K-D test was administered before and after a counterbalanced exercise or rest intervention. Reliability was assessed using testing visits (visit 1 and visit 2) as the independent variables. Exercise or rest and time (baseline, postintervention) were used as independent variables to examine the influence of exercise. MAIN OUTCOME MEASURES: Intraclass correlation (ICC) coefficients with 95% confidence intervals were calculated between visits to assess reliability of K-D test completion time. A repeated-measure 2 x 2 analysis of variance (intervention * time) with post hoc paired t tests was used to assess the influence of exercise on K-D test performance. RESULTS: The K-D test was observed to have strong test-retest reliability [ICC2,1 = 0.90 (0.71, 0.96)] over time. No significant intervention-by-time interaction (P = 0.55) or intervention main effects (P = 0.68) on K-D time were observed. Mean differences of -1.5 and -1.7 seconds (P < 0.001) were observed between baseline and rest and exercise interventions for K-D test performance, respectively. Up to 32% (20/63) of participants were observed to have a false-positive K-D test performance before and after each intervention. CONCLUSIONS: Although strong test-retest reliability coefficients were observed using clinically relevant time points, a high false-positive rate warrants caution when interpreting the K-D test. PMID- 29601348 TI - Association Between a Physical Activity Vital Sign and Cardiometabolic Disease in High-Risk Patients. AB - OBJECTIVE: To determine the association between the physical activity vital sign (PAVS) and markers of cardiometabolic disease. DESIGN: Patients were assessed through the PAVS, a validated tool self-reporting the frequency and duration of physical activity. Patients were categorized into 3 groups: inactive (0 minutes per week), underactive (1-149 minutes per week), and active (>150 minutes per week). Associations were tested between the PAVS and the cardiometabolic disease biomarkers of body mass index, hemoglobin A1c (A1c), blood pressure, and low density lipoprotein (LDL) using one-way analyses of variance. SETTING: High-risk family medicine residency clinic. PARTICIPANTS: Two thousand three hundred twenty one adult patients (age >= 18 years). RESULTS: Participants reported a mean of 97.87 (SD = 149.35) minutes per week of exercise. Overall, 50.1% reported physical inactivity, 25.7% were underactive, and 24.3% were active. Younger individuals (P < 0.001) and men (P < 0.05) reported more physical activity than older individuals and women. Patients who reported being active were significantly less likely to be overweight (P < 0.05), obese (P < 0.05), or hypertensive (P < 0.05), but there was no association with A1c or LDL levels. CONCLUSIONS: This is the first investigation to examine the PAVS in a high-risk population. In these patients, reported levels of physical inactivity are 150% higher than other clinical settings, and the PAVS is only associated with improvements in 2 of 4 major cardiometabolic risk factors. For this group, self reported levels of physical activity may need to be higher for cardiovascular benefits to be realized in all 4 cardiometabolic domains. The PAVS offers health professionals an opportunity to encourage lifestyle-based interventions to reduce cardiovascular risk, but refinements may be necessary to address this population. PMID- 29601349 TI - Factors Associated With Self-Reported Concussion History in Middle School Athletes. AB - OBJECTIVE: Identifying personal characteristics associated with sustaining a concussion is of great interest, yet only a few have examined this in children. The purpose of this study was to examine the association between sex, neurodevelopmental disorders, health history, and lifetime history of self reported concussion in 12- and 13-year-old athletes. DESIGN: Cross-sectional study. SETTING: Middle schools. PARTICIPANTS: Participants were 1744 twelve- and thirteen-year-old student athletes who completed preseason Immediate Post Concussion Assessment and Cognitive Testing (ImPACT) testing, including a self report questionnaire about previous concussions, developmental diagnoses, and previous medical treatment. INDEPENDENT VARIABLES: Age, sex, attention deficit/hyperactivity disorder (ADHD), learning disabilities (LDs), and previous treatment for migraine. MAIN OUTCOME MEASURES: Self-reported history of concussion. RESULTS: A minority of athletes (13.7%) reported previous concussions (1 concussion, n = 181; 2 concussions, n = 41; and 3+ concussions, n = 17). A small proportion reported a history of ADHD (4.4%), LD (2.8%) or migraine treatment (4.0%). Higher rates of self-reported previous concussions were associated with male sex (16.9% vs 9.1%; chi(1) = 21.47, P < 0.001) and previous migraine treatment (31.9% vs 13.0%; chi(1) = 20.08, P < 0.001). There were no differences in self-reported concussion history between 12- and 13-year olds (P = 0.18) and those with/without ADHD (P = 0.41) or LDs (P = 0.06). The overall logistic regression model was statistically significant (chi(5) = 42.01, P < 0.001) but explained only 4.3% of the variance. Previous treatment for migraine (P < 0.001, Exp(B) = 3.30) and male sex (P < 0.001, Exp(B) = 2.06) were independently associated with a self-reported concussion history, whereas age, LD, and ADHD were not (P's > 0.05). CONCLUSIONS: Male sex and previous migraine treatment were associated with higher rates of self-reported previous concussions in both independent and multivariate models in middle school athletes, whereas age, ADHD, and LDs were not. PMID- 29601350 TI - In Response to: Impact of CrossFit-Related Spinal Injuries. PMID- 29601351 TI - How to predict and improve prognosis of food allergy. AB - PURPOSE OF REVIEW: The prevalence of food allergy is increasing. More children are being diagnosed with food allergies, and it is taking longer to outgrow them, among those who develop tolerance. The aim of this review is to draw the profile of the persistent food allergic, so that prevention strategies can be developed and active treatment set up. RECENT FINDINGS: Many determinants are involved in food allergy prognosis: ethnicity and sex, type of food, innate immune system, eliciting dose, sensitization status and other biomarkers determination, gut microbiome composition, and the presence of comorbidities. Once identified, a persistent food allergy could be conveyed to active treatments, such as oral immunotherapy or the use of biologics, always taking into account their experimental nature. SUMMARY: A better understanding of prognostic factors and phenotypes of food allergy is crucial in decision-making when it comes to food allergy prevention and management. A good classification of the allergic patient allows to determine the degree of exclusion diets and the timing of the reintroduction of avoided food when possible. In the cases of persistent and severe food allergy, many promising interventions are emerging which could improve prognosis and quality of care. PMID- 29601352 TI - Avenues for research in food allergy prevention: unheeded ideas from the epidemiology. PMID- 29601353 TI - How to diagnose food allergy. AB - PURPOSE OF REVIEW: To assess the recent studies that focus on specific immunoglobulin E (sIgE) testing and basophil activation test (BAT) for diagnosing IgE-mediated food allergies. RECENT FINDINGS: The sIgE to allergen extract or component can predict reactivity to food. The cutoff value based on the positive predictive value (PPV) of sIgE can be considered whenever deciding whether oral food challenge (OFC) is required to diagnose hen's egg, cow's milk, wheat, peanut, and cashew nut allergy. However, PPV varies depending on the patients' background, OFC methodology, challenge foods, and assay methodology. Component resolved diagnostics (CRD) has been used for food allergy diagnosis. Ovomucoid and omega-5 gliadin are good diagnostic markers for heated egg and wheat allergy. More recently, CRD of peanut, tree nuts, and seed have been investigated. Ara h 2 showed the best diagnostic accuracy for peanut allergy; other storage proteins, such as Jug r 1 for walnut, Ana o 3 for cashew nut, Ses i 1 for sesame, and Fag e 3 for buckwheat, are also better markers than allergen extracts. Some studies suggested that BAT has superior specificity than skin prick test and sIgE testing. SUMMARY: The sIgE testing and BAT can improve diagnostic accuracy. CRD provides additional information that can help determine whether OFCs should be performed to diagnose food allergy. PMID- 29601354 TI - Phenotypes/endotypes-driven treatment in asthma. AB - PURPOSE OF REVIEW: Target therapy is the necessary step towards personalized medicine. The definition of asthma phenotypes and underlying mechanisms (endotypes) represent a key point in the development of new asthma treatments. Big data analysis, biomarker research and the availability of monoclonal antibodies, targeting specific cytokines is leading to the rapid evolution of knowledge. In this review, we sought to outline many of the recent advances in the field. RECENT FINDINGS: Several attempts have been made to identify asthma phenotypes, sometimes with contrasting results. More success has been obtained concerning the pathogenetic mechanism of specific asthma patterns with the consequent identification of biomarkers and development of effective ad hoc treatment. SUMMARY: We are in the middle of an extraordinary revolution of our mode of thinking about and approaching asthma. All the effort in the identification of clusters of patients with different disease clinical patterns, prognosis and response to treatment is closely linked to the identification of endotypes (Th2-low and Th2-high). This approach has allowed the development of the specific treatments (anti IgE, Anti IL5 and IL5R) that are now available and is leading to new ones. PMID- 29601355 TI - How to prevent food allergy during infancy: what has changed since 2013? AB - PURPOSE OF REVIEW: The purpose of this review is to summarize recent studies and emerging consensus guidelines regarding food allergy prevention in infants of the past 5 years. RECENT FINDINGS: Prior to 2013, the general consensus regarding prevention of food allergy in infants was to recommend delayed introduction or complete avoidance of commonly allergenic foods, such as milk, egg and peanut. However, in the past 5 years, several landmark studies have been conducted, particularly with peanut. The results of these studies have led to a paradigm shift from recommending delayed introduction to early introduction and frequent feeding of highly allergenic foods such as peanut, with hopes of achieving primary and secondary prevention of food allergy in infants. SUMMARY: Recent clinical trials have demonstrated that early introduction and frequent feeding, rather than delayed introduction or complete avoidance, of commonly allergenic foods plays a critical role in preventing food allergy in infants. More studies are required to risk-stratify infants by personal and family atopic history to tailor guidelines for groups with inherently different risks. The universal acceptance of the guidelines and their application outcome are still to be determined. PMID- 29601356 TI - Current opinion in allergy and clinical immunology: a change in leadership. PMID- 29601357 TI - Application of precision medicine to the treatment of anaphylaxis. AB - PURPOSE OF REVIEW: Recognize the presentation of anaphylaxis for prompt management and treatment and to provide tools for the diagnosis of the underlying cause(s) and set up a long-term treatment to prevent recurrence of anaphylaxis. RECENT FINDINGS: The recent description of phenotypes provides new insight and understanding into the mechanisms and causes of anaphylaxis through a better understanding of endotypes and biomarkers for broad clinical use. SUMMARY: Anaphylaxis is the most severe hypersensitivity reaction and can lead to death. Epinephrine is the first-line treatment of anaphylaxis and it is life-saving. Patients with first-line therapy-induced anaphylaxis are candidates for desensitization to increase their quality of life and life expectancy. Desensitization is a breakthrough novel treatment for patients with anaphylaxis in need of first-line therapy, including chemotherapy, mAbs, aspirin and others. Ultrarush with venom immunotherapy should be considered in patients who present with life-threatening anaphylaxis after Hymenoptera sting with evidence of IgE mediated mechanisms. Food desensitization is currently being expanded to provide increased safety to adults and children with food-induced anaphylaxis. PMID- 29601358 TI - A Meta-analysis of the Association Between Physical Activity and Breast Cancer Mortality. AB - BACKGROUND: There are conflicting data on the association between physical activity (PA) intensity and amount and prognosis of breast cancer. It is unknown whether increasing or decreasing PA is associated with all-cause mortality. OBJECTIVE: The purpose of this study was to estimate the associations between PA and the risk of mortality. METHODS: MEDLINE and EMBASE were used to find eligible studies published from January 1970 to March 2017 for this meta-analysis. We included 24 studies, with a total of 144 224 patients and follow-up periods ranging from 1.9 to 12.7 years. We categorized the amount of PA as low (<300 min/wk), moderate (300-500 min/wk), and high (>500 min/wk). RESULTS: We found that high amounts of PA had an inverse relationship with breast-cancer-specific mortality and all-cause morality. Patients who decreased PA after diagnosis showed poorer all-cause mortality, whereas patients who increased PA postdiagnosis had a favorable association with all-cause mortality. Last, patients who met PA guidelines after diagnosis had a lower breast-cancer-specific mortality and all-cause mortality. CONCLUSION: Physical activity may play a pivotal role in reducing the risk of death. Getting at least 300 min/wk of moderate-intensity PA will help improve the risk of breast cancer death. IMPLICATIONS FOR PRACTICE: Participating in PA is an essential factor in breast cancer care that extends throughout the life span of cancer survivors. Higher levels of PA than current PA guidelines should be recommended to cancer patients. PMID- 29601359 TI - Representations of Young Cancer Survivorship: A Discourse Analysis of Online Presentations of Self. AB - BACKGROUND: More young people are surviving treatment for cancer than ever before. Survival can have an adverse impact on their transition to adulthood. Discourses of cancer are applied to cancer survivors of all ages, but they manifest differently for young people. OBJECTIVE: The aim of this study was to describe practices of self-representation in an online Web site that supports young Australian cancer survivors. METHOD: We conducted a discourse analysis of images and text produced by young cancer survivors (aged 18-35 years) on a public cancer charity Web site. RESULTS: The dominant subject position of participants published on this web site is one of empowered, beautiful cancer survivor. This applies to young people who have learned to embrace their cancer as providing a positive influence on their lives. However, this discourse can marginalize those whose cancer experience remains a source of distress or shame. CONCLUSION: Web based media can provide a valuable forum for some young people to celebrate their cancer survival and to affirm the constructive influence that their cancer experience has had on their lives. However, we ponder the apparent unsuitability of some forums for young cancer survivors who have not yet found cause for celebration. IMPLICATIONS FOR PRACTICE: Nurses have the opportunity to contribute to the development of supportive structures that meet the specific needs of different groups of young cancer survivors. This might mean assisting young cancer survivors who are struggling to find meaning in their cancer experience to negotiate the establishment of a new normal that they can embrace. PMID- 29601360 TI - Using a Patient-Centered Approach to Identify Symptom Clusters Among Adolescents With Cancer. AB - BACKGROUND: Prior studies identifying symptom clusters used a symptom-centered approach to demonstrate the relationship among symptoms. Latent profile analysis (LPA) is a patient-centered approach that classifies individuals from a heterogeneous population into homogeneous subgroups, helping prioritize interventions to focus on clusters with the most severe symptom burden. OBJECTIVE: The aim of this study was to use LPA to determine the best-fit models and to identify phenotypes of severe symptom distress profiles for adolescents with cancer who are undergoing treatment and in survivorship. METHODS: We used estimated means generated by the LPA to predict the probability of an individual symptom occurring across on- and off-treatment groups for 200 adolescents with cancer. RESULTS: The 3-profile solution was considered the best fit to the data for both on- and off-treatment groups. Adolescents on treatment and classified into the severe profile were most likely to report distress in appetite, fatigue, appearance, nausea, and concentration. Adolescents off treatment and classified into the severe profile were most likely to report distress in fatigue, pain frequency, and concentration. CONCLUSIONS: Latent profile analysis provided a cluster methodology that uncovered hidden profiles from observed symptoms. This made it possible to directly compare the phenotypes of severe profiles between different treatment statuses. IMPLICATIONS FOR PRACTICE: The co-occurring 13-item Symptom Distress Scale symptoms found in the severe symptom distress profiles could be used as items in a prespecified severe symptom distress cluster, helping evaluate a patient's risk of developing varying degrees of symptom distress. PMID- 29601361 TI - How Interdisciplinary Teamwork Contributes to Psychosocial Cancer Support. AB - BACKGROUND: The organization of psychosocial care is rather complex, and its provision diverse. Access is affected by the acceptance and attitude of patients and professional caregivers toward psychosocial care. OBJECTIVES: The aims of this study were to examine when patients with cancer experience quality psychosocial care and to identify circumstances in collaboration that contribute to patient-perceived positive psychosocial care. METHODS: This study used a qualitative design in which semistructured interviews were conducted with patients, hospital workers, and primary health professionals. RESULTS: Psychosocial care is often requested but also refused by patients with cancer. Based on this discrepancy, a distinction is made between psychosocial support and psychosocial interventions. Psychosocial support aims to reduce the chaos in patients' lives caused by cancer and is not shunned by patients. Psychosocial interventions comprise the formal care offered in response to psychosocial problems. Numerous patients are reluctant to use psychosocial interventions, which are often provided by psychologists. CONCLUSION: Psychosocial care aims to assist patients in bearing the difficulties of cancer and its treatment. Patients prefer informal support, given often in conjunction with physical care. IMPLICATIONS FOR PRACTICE: This study confirms the important role of nurses in promoting psychosocial care. Patients perceive much support from nurses, although nurses are not considered to be professional psychosocial caregivers. Being perceived as approachable and trustworthy offers nurses a significant opportunity to bring more intense psychosocial interventions within reach of cancer patients. PMID- 29601362 TI - Roles of Family Caregivers and Perceived Burden When Caring for Hospitalized Adult Cancer Patients: Perspective From a Low-Income Country. AB - BACKGROUND: Family caregivers (FCGs) of adult cancer patients (ACPs) are typically involved in the entire trajectory of cancer disease, from diagnosis to survivorship or end of life. In developing countries, FCGs are more intensely involved in the process of providing care to the hospitalized ACPs because of lack of adequate cancer care resources. Active performance of tasks to meet the needs of ACPs in the hospital setting is likely to elicit significant caregiver burden. OBJECTIVE: The aim of this study was to explore the tasks performed and the caregiver burden experienced by FCGs of hospitalized ACPs in a sub-Saharan country. METHODS: A cross-sectional descriptive design was used to collect data from 168 FCGs of ACPs. The Caregiver Burden Scale was used to measure burden. RESULTS: The most common cancer diagnosis in male and female ACPs was Kaposi's sarcoma (32.1%) and breast cancer (37.9%), respectively. The tasks regularly performed by most FCGs for the ACPs were providing emotional support (79.8%), feeding (68.5%), transporting to other appointments (62.5%), preparing meals (55%), and giving medications (46.4%). Most FCGs (75%) were experiencing severe or very severe general caregiver burden. The dimensions of caregiver burden that were most severely impacted were general strain (70.6%), disappointment (85.8%), and isolation (72%). Predictors of caregiver burden are reported. CONCLUSION: Family caregivers of hospitalized ACPs experience severe caregiver burden. The main forms of burden experienced were general strain, disappointment, and isolation. IMPLICATIONS FOR PRACTICE: Cancer care services in developing countries should be strengthened with services that address FCGs' emotional needs and human resources to curtail the strain imposed on FCGs. PMID- 29601363 TI - Outcomes of Trabeculectomy and Glaucoma Drainage Devices for Elevated Intraocular Pressure After Penetrating Keratoplasty. AB - PURPOSE: To assess and compare the outcomes of trabeculectomy with and without antimetabolites (AMs) and glaucoma drainage devices (GDDs) in the management of elevated intraocular pressure (IOP) after penetrating keratoplasty (PK). METHODS: Data of 84 eyes of 81 patients who underwent trabeculectomy (12 eyes without an AM and 42 eyes with an AM) or GDD implantation (30 eyes) after PK were reviewed retrospectively. The main outcome measures were IOP control, corneal graft survival, and postoperative ocular complications. RESULTS: At the final visit, IOP success (<22 mm Hg) was 58.3% in trabeculectomy alone, 64.3% in trabeculectomy with an AM (TrabAM), and 86.7% in GDD groups (P = 0.047). The median time from surgery to IOP failure was 1 month after trabeculectomy alone, 13 months after TrabAM, and 20 months after GDD implantation (P = 0.042). The cumulative probability of IOP success rates at 1 and 3 years postoperatively was as follows: 66.7% and 57.1% in trabeculectomy alone, 80.6% and 64.8% in TrabAM, and 92.3% and 84.6 in GDD groups (P = 0.063). The cumulative probability of corneal graft survival rates at 1 and 3 years postoperatively was as follows: 70.0% and 60.0% in trabeculectomy alone, 76.7% and 67.7% in TrabAM, and 65.8% and 52.6% in GDD groups (P = 0.549). CONCLUSIONS: GDDs are more successful than trabeculectomy in controlling IOP in eyes that have undergone PK, but they tend to have low corneal graft survival rates. Trabeculectomy without an AM has limited success and may be considered in a limited number of patients with a low risk for bleb failure. PMID- 29601365 TI - Adjuvant Use of Cyclosporine A in the Treatment of Primary Pterygium: A Systematic Review and Meta-Analysis. AB - PURPOSE: To evaluate the efficacy and tolerability of cyclosporine A (CsA) as an adjuvant treatment for primary pterygium. METHODS: A comprehensive literature search from 7 databases (EMBASE, ISI Web of Science, PubMed, and the Cochrane Library for studies published in English and VIP, Wan Fang, and CNKI for studies published in Chinese). For the recurrence rate, pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model. Tolerability estimates were measured by OR for adverse events. RESULTS: A total of 7 studies meeting the inclusion criteria were included in this meta-analysis. Compared with the group with adjunctive CsA usage, the control group (no adjuvant use of CsA) showed a significantly increased risk of pterygium recurrence (OR = 2.71; 95% CI, 1.62-4.54). No obvious heterogeneity was detected in the included studies. Subgroup analysis showed that adjuvant use of CsA with pterygium excision alone resulted in a significantly lower frequency of recurrence than was seen in the group without adjuvant use of CsA (OR = 3.16; 95% CI, 1.18-8.84). However, there is no significant difference in pterygium recurrence between the subgroup (CsA + pterygium excision + limbal conjunctival autograft or flap rotation) and the subgroup without adjunctive CsA usage (pterygium excision + limbal conjunctival autograft or flap rotation). CONCLUSIONS: This meta-analysis suggests that adjuvant use of CsA can significantly reduce the risk of pterygium recurrence compared with pterygium excision alone, whereas adjuvant use of CsA may not reduce the risk of pterygium recurrence in terms of pterygium excision + limbal conjunctival autograft or conjunctival flap rotation. PMID- 29601364 TI - Corneal Cross-Linking for Pediatric Keratcoconus Review. AB - PURPOSE: To comprehensively review the available published literature for cross linking in the pediatric population. METHODS: Review of the literature published in English in PubMed. RESULTS: Two hundred ten publications were considered. One hundred fifteen were considered relevant to this review. CONCLUSIONS: Studies of cross-linking in pediatric patients are sparse, with relatively short follow-up times, and mostly on small groups of patients. Treatment with cross-linking halts progression of keratoconus in the pediatric population, and early treatment seems to be cost-effective compared with later penetrating keratoplasty. Long-term effects and regression rates remain unclear, and further studies are needed in this population. PMID- 29601366 TI - Risk of Anterior Segment Complications Associated With the Live Herpes Zoster Vaccine: Evidence From a Health-Claim Database. AB - PURPOSE: To determine the risk of developing anterior segment complications after receiving the live herpes zoster virus vaccine. METHODS: This retrospective cohort study included a random sample of 9 million patients registered in a health-claim database in the United States between 2006 and 2016. Herpes zoster related anterior segment diseases were identified by International Classification of Diseases ninth or tenth edition codes (an event). Patients without any event before index dates were separated into cohorts 1 and 2. Cohort 1 received the live virus vaccine on the index date. Cohort 2 was diagnosed with nonophthalmic zoster on the index date. The recurrent cohorts consisted of those who had an event 6 months or more before the index dates and were separated into cohort 3 and cohort 4 based on the same criteria as cohort 1 and 2, respectively. All cohorts were followed to the first event. Hazard ratios (HRs) of anterior segment complications after vaccine administration were determined. RESULTS: There were 72,141 vaccine users and 133,604 nonusers. There were 379 events and 1032 events in cohort 1 and cohort 2, respectively. The adjusted HR was 0.89 (95% confidence interval: 0.77-1.02). Among those with recurrent disease, there were 2679 vaccine users and 9421 nonusers. There were 16 events in cohort 3, compared with 86 events in cohort 4. The adjusted HR was 0.70 (95% confidence interval: 0.40 1.23). CONCLUSIONS: Data from a large health-claim database suggest that the live zoster virus vaccine is not associated with a higher risk of anterior segment complications. PMID- 29601368 TI - Heart Failure Self-care Within the Context of Patient and Informal Caregiver Dyadic Engagement: A Mixed Methods Study. AB - BACKGROUND: Recent heart failure (HF) patient and informal caregiver (eg, dyadic) studies have either examined self-care from a qualitative or quantitative perspective. To date, the 2 types of data have not been integrated. OBJECTIVE: The aim of this study was to understand HF self-care within the context of dyadic engagement. METHODS: This was a cross-sectional, mixed methods (quantitative/qualitative) study. Heart failure self-care was measured with the Self-care of Heart Failure Index (v.6) dichotomized to adequate (>=70) or inadequate (<69). Dyadic symptom management type was assessed with the Dyadic Symptom Management Type scale. Interviews regarding self-care were conducted with both dyad members present. Content analytic techniques were used. Data were integrated using an information matrix and triangulated using Creswell and Plano Clark's methods. RESULTS: Of the 27 dyads, HF participants were 56% men, with a mean age of 77 years. Caregivers were 74% women, with a mean age of 66 years, representing spouses (n = 14) and adult children (n = 7). Quantitatively, few dyads scored as adequate (>=70) in self-care; the qualitative data described the impact of adequacy on the dyads' behavior. Dyads who scored higher, individually or both, on self-care self-efficacy and self-care management were less likely to change from their life course pattern. Either the patient or dyad continued to handle all self-care as they always had, rather than trying new strategies or reaching out for help as the patient's condition deteriorated. CONCLUSIONS: Our data suggest links that should be explored between dyadic adequacy and response to patients' symptoms. Future studies should assess dyadic adequacy longitudinally and examine its relationship to event-free survival and health services cost. PMID- 29601369 TI - Quality of Life for Parents of Children With Congenital Heart Defect: A Systematic Review. AB - BACKGROUND: As survival rates for infants born with severe forms of cardiac defects (congenital heart defect [CHD]) improve, attention is directed to evaluating factors that affect the child's short- and long-term outcomes including parental quality of life (QOL). PURPOSE: The purpose of this review was to identify how parental QOL is affected when having a child with a CHD. Factors that influence parental QOL when having a child with a CHD will also be described. METHODS: A systematic search of CINAHL, EMBASE, PsycINFO, and PubMed databases was performed. Thirty-three quantitative cross-sectional or cohort studies were selected for inclusion and analyzed for quality reporting using Strengthening the Reporting of Observational Studies in Epidemiology guidelines. RESULTS: Heart defect severity, age of child, perceived support, and availability of economic resources were identified as factors affecting parental QOL. Parent gender was related to QOL and family functioning factors. Paternal outcomes were reported in 23 of the 33 studies (70%), with an average father participation rate of 40%. CONCLUSIONS: Having a child with CHD negatively affects parental QOL. Future research should include targeting fathers to improve understanding of their unique perceptions and needs. Longitudinal studies should also describe correlations of parental QOL with their child's developmental outcomes. Efficacy studies testing supportive interventions on outcomes such as improved adjustment and QOL are needed. PMID- 29601367 TI - Design and Rationale of the Cognitive Intervention to Improve Memory in Heart Failure Patients Study. AB - BACKGROUND: Memory loss is an independent predictor of mortality among heart failure patients. Twenty-three percent to 50% of heart failure patients have comorbid memory loss, but few interventions are available to treat the memory loss. The aims of this 3-arm randomized controlled trial were to (1) evaluate efficacy of computerized cognitive training intervention using BrainHQ to improve primary outcomes of memory and serum brain-derived neurotrophic factor levels and secondary outcomes of working memory, instrumental activities of daily living, and health-related quality of life among heart failure patients; (2) evaluate incremental cost-effectiveness of BrainHQ; and (3) examine depressive symptoms and genomic moderators of BrainHQ effect. METHODS: A sample of 264 heart failure patients within 4 equal-sized blocks (normal/low baseline cognitive function and gender) will be randomly assigned to (1) BrainHQ, (2) active control computer based crossword puzzles, and (3) usual care control groups. BrainHQ is an 8-week, 40-hour program individualized to each patient's performance. Data collection will be completed at baseline and at 10 weeks and 4 and 8 months. Descriptive statistics, mixed model analyses, and cost-utility analysis using intent-to-treat approach will be computed. CONCLUSIONS: This research will provide new knowledge about the efficacy of BrainHQ to improve memory and increase serum brain-derived neurotrophic factor levels in heart failure. If efficacious, the intervention will provide a new therapeutic approach that is easy to disseminate to treat a serious comorbid condition of heart failure. PMID- 29601370 TI - Associations of Vitamin D Intake and Sleep Quality With Cognitive Dysfunction in Older Adults With Heart Failure. AB - BACKGROUND: Low vitamin D intake and poor sleep quality are independently associated with cognitive dysfunction in healthy older adults. However, the relationships among vitamin D intake, sleep quality, and cognitive dysfunction are unknown in older adults with heart failure (HF). PURPOSE: The aim of this study was to determine the relationships of vitamin D intake and sleep quality with cognitive dysfunction in older adults with HF. METHODS: A total of 160 older adults with HF completed the Mini-Mental State Examination to assess cognitive function. Vitamin D deficiency was defined as less than 15 mcg/day of average intake determined using a 3-day food diary and use of dietary supplements. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). Hierarchical regressions and mediation analysis were used for data analysis. RESULTS: Thirty four patients (21.2%) had severe cognitive dysfunction (total Mini-Mental State Examination score <= 19), 88 (55%) had vitamin D deficiency, and 120 (75%) reported poor sleep quality (total PSQI score > 5). Increased daily vitamin D intake (beta = 0.305, P < .001) and poorer sleep quality indicated by the total PSQI score (beta = -0.312, P < .001) were associated with cognitive function. Vitamin D deficiency was associated with poor sleep quality (odds ratio, 2.22; P = .033). In mediation analysis, the relationship between vitamin D deficiency and cognitive function was mediated by sleep quality among older adults with HF. CONCLUSIONS: Both vitamin D deficiency and poor sleep quality are associated with cognitive dysfunction in older adults with HF. Interventions should be tested to target patients with poor sleep quality to improve cognitive function, particularly in those with vitamin D deficiency. PMID- 29601371 TI - A Survey on Sexual Counseling for Patients With Cardiac Disease Among Nurses in Jordan. AB - BACKGROUND: Recovery among patients with cardiac disease also requires attention to their sexual health. However, cultural, religious, and social factors may make Arab Muslim patients reluctant to disclose their sexual concerns and nurses hesitant to discuss patients' sexuality matters. OBJECTIVE: The aim of this study was to explore sexual counseling (SC) among nurses in Jordan in terms of responsibility, confidence, and practice. METHOD: This was a descriptive, correlational study. Staff nurses were recruited from 10 hospitals in Jordan. Nurses completed the cardiac version of the Survey of Sexuality-Related Nursing Practice and reported their demographics. RESULTS: The sample consisted of 379 nurses (female, 59%; mean age, 28.1 years). A significant proportion of nurses viewed assessment/discussion of patients' sexuality matters as not within their responsibilities (39%), did not feel confident to address sexuality matters (50%), and rated themselves as not at all/not very knowledgeable about sexuality (60%). Few nurses were routinely integrating SC in clinical practice (9%). Sexual counseling was associated with nurses' gender (male, higher confidence and practice) and previous training on sexuality in nursing practice. CONCLUSIONS: Nurses in Jordan, especially female nurses, are neither prepared nor competent to provide SC. Nurses need focused education on sexuality to optimize patients' sexual health. PMID- 29601372 TI - Illness Uncertainty and Posttraumatic Stress in Young Adults With Congenital Heart Disease. AB - BACKGROUND: Young adults with congenital heart disease (CHD) are at risk for chronic illness uncertainty in 4 domains: ambiguity about the state of their illness; lack of information about the disease, its treatment, and comorbidities; complexity of the healthcare system and relationship with healthcare providers; and unpredictability of the illness course and outcome. Chronic uncertainty has been associated with posttraumatic stress symptoms (PTSS) and posttraumatic stress disorder (PTSD). OBJECTIVE: The aims of this study were to explore how young adults with CHD experience uncertainty and to describe the relationship between PTSS and the appraisal and management process. METHODS: An exploratory, mixed methods design was used. Data were collected in person and via Skype from 25 participants (19-35 years old), who were diagnosed with CHD during childhood and able to read and write English. In-depth interviews and the University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index were used to collect data. Qualitative data were analyzed using the constant comparative method. RESULTS: The 4 domains of uncertainty were evident in the narratives. The PTSD mean (SD) score was 31.3 (7.7). Six participants met criteria for PTSD. Narrative analysis revealed a relationship between severity of PTSS and the appraisal and management of uncertainty. Participants with PTSD used management strategies that included avoidance, reexperiencing, and hyperarousal. CONCLUSIONS: Young adults with CHD may be at risk for the development of long term psychological stress and PTSD in the setting of chronic uncertainty. Regular monitoring to identify PTSS/PTSD may be a means to promote treatment adherence and participation in healthcare. PMID- 29601373 TI - Decreased Quality of Life Due to Driving Restrictions After Cardioverter Defibrillator Implantation. AB - BACKGROUND: Driving restrictions for patients with an implantable cardioverter defibrillator (ICD) may require significant lifestyle adjustment and affect patients' psychological well-being. This study explored the prevalence of, and factors associated with, patient-reported decrease in quality of life due to driving restrictions in the first 2 months postimplantation. METHODS: Dutch ICD patients (N = 334; median age, 64 [interquartile range, 55-70) years; 81% male) completed questionnaires at the time of implantation and 4 months postimplantation, assessing their sociodemographic, psychological, and driving related characteristics. Clinical baseline data were retrieved from patients' medical records. RESULTS: Nearly half of the patients (49%) reported decreased quality of life due to driving restrictions. Patient-reported reasons included dependency on others/public transport, (social) isolation, and inability to work. Patients reporting decreased quality of life were more likely to be younger (P = .01), to feel that the restriction lasts too long (P = .004), to have considered ICD refusal because of the restrictions (P = .03), and to have Type D personality (P = .02), anxiety (P = .05), depression (P = .003), and ICD-related concerns (P = .02). Multivariable analysis showed that being younger than 60 years (odds ratio [OR], 2.30; 95% confidence interval [CI], 1.09-4.88; P = .03), feeling the driving restriction lasts too long (OR, 1.77; 95% CI, 1.23-2.55; P = .002), and depression (OR, 3.21; 95% CI, 1.09-9.47; P = .035) were independently associated with decreased quality of life due to driving restrictions. CONCLUSIONS: This study indicated that a significant group of ICD patients may experience decreased quality of life because of the driving restrictions postimplantation. The restrictions seem to particularly affect patients who are younger and distressed and patients who feel that the restriction lasts too long.

PMID- 29601374 TI - User-centered Development of a Decision Aid for Patients Facing Implantable Cardioverter-Defibrillator Replacement: A Mixed-Methods Study. AB - BACKGROUND: Because of battery depletion, an implantable cardioverter defibrillator (ICD) generator requires surgical replacement every 5 to 7 years. Routine replacement is the norm without discussion with patients about whether or not to proceed. OBJECTIVE: The aim of this study was to develop a patient decision aid (PDA) for patients facing ICD replacement and plan for its implementation. METHODS: An embedded mixed-methods study was conducted using questionnaires and semistructured interviews focused on current ICD replacement practices; PDA acceptability, usability, and content; and PDA implementation. Transcripts were analyzed using constant comparative analysis. RESULTS: Eighteen PDA end users in 16 interviews characterized the current ICD replacement approach as automatic without consideration for patient preferences. The PDA was positively received, and the content was iteratively revised 4 times during the interviews. Changes were related to missing and excess information, language, and wording. The PDA was identified as a means to support a shared decision-making (SDM) process, not to be used as a standalone instrument. To shift current practices to an SDM process, participants identified that an invitation to discuss the option of ICD replacement is required-whether initiated by the patient or the clinician. CONCLUSION: Currently, the option of ICD replacement is rarely offered, and patient preferences are seldom elicited. Participants believed the PDA to be a useful intervention that could help facilitate an SDM process for patients facing ICD replacement. Preparing for implementation during the development phase will allow us to strategize effectively to overcome perceived barriers and capitalize on perceived facilitators during actual implementation. PMID- 29601376 TI - The Influence of beta-Adrenergic Receptor Kinase-1 on Stroke-induced Immunodeficiency Syndrome. AB - BACKGROUND: Immunodeficiency in acute ischemic stroke (AIS) is thought to be a result of norepinephrine suppression of the lymphoid tissue. The possible differences in the distribution of lymphocytes after stroke may be due to differences in responsiveness of lymphocyte beta-adrenergic receptors to their kinase (BARK-1). OBJECTIVE: The objective was to quantify the influence of lymphocyte BARK-1 on stroke-induced immunodeficiency in AIS patients. METHODS: A prospective clinical cohort study was conducted (N = 44). Measures included age, gender, race, risk factors for stroke, stroke severity, comorbidities, presence of infection, white blood cell counts and differential proportions, and lymphocyte BARK-1. Student t tests, effect sizes, and linear and logistic regressions were conducted to test the study objective. The study was approved by the Oregon Health & Science University Institutional Review Board. RESULTS: There were significant changes in all white blood cells and differential proportions and in the National Institutes of Health Stroke Scale from admission to 48 hours after onset of stroke deficits. Higher BARK-1 influenced the lower lymphocyte proportion at 48 hours, independent of age, P < .0001. Furthermore, BARK-1 also was associated with an increase in the likelihood of having sustained or stroke induced immunodeficiency at 48 hours: odds ratio, 2.41; 95% confidence interval, 1.10-5.25; P = .027, and odds ratio, 2.79; 95% confidence interval, 1.03-7.52; P = .043, respectively. In all backward stepwise selection of factors, BARK-1 was the only factor consistently retained in the models. CONCLUSIONS: beta-Adrenergic receptor kinase-1 has a significant quantifiable influence on lymphocyte proportion at 48 hours and on the classification of sustained stroke-induced immunodeficiency. CLINICAL IMPLICATIONS: beta-Adrenergic stimulation influences immunodeficiency in AIS. PMID- 29601377 TI - Seasonal Work and Cardiovascular Risk Factors in Farmers. AB - BACKGROUND: Cardiovascular disease is the leading cause of death and hospitalization in the rural United States. Midwestern farmers are integral to rural communities, but little is known about the effect of occupational variability of seasonal work and technology use on their cardiovascular disease risk. AIMS: This study describes the relationships of health behaviors and cardiovascular disease risk in 40 Midwestern farmers during peak and off-peak farming seasons. METHODS: Objectively measured physical activity and self-report of demographics, diet, and health-related quality of life were collected during each farming season. RESULTS AND CONCLUSIONS: Farmers in this study were physically active, ate consistent diets, and reported high health status ratings throughout the year. Cardiovascular disease risk was positively correlated with age and body mass index (P < .01), and half of young and middle-age farmers reported anxiety and depression problems. Cardiovascular disease risk reduction interventions for farmers should address both physical and emotional aspects of farming. PMID- 29601378 TI - Is Anesthesia Technique Associated With a Higher Risk of Mortality or Complications Within 90 Days of Surgery for Geriatric Patients With Hip Fractures? AB - BACKGROUND: Postoperative mortality and complications after geriatric hip fracture surgery remain high despite efforts to improve perioperative care for these patients. One factor of particular interest is anesthetic technique, but prior studies on this are limited by sample selection, competing risks, and incomplete followup. QUESTIONS/PURPOSES: (1) Among older patients undergoing surgery for hip fracture, does 90-day mortality differ depending on the type of anesthesia received? (2) Do 90-day emergency department returns and hospital readmissions differ based on anesthetic technique after geriatric hip fracture repairs? (3) Do 90-day Agency for Healthcare Research and Quality (AHRQ) outcomes differ according to anesthetic techniques used during hip fracture surgery? METHODS: We conducted a retrospective study on geriatric patients (65 years or older) with hip fractures between 2009 and 2014 using the Kaiser Permanente Hip Fracture Registry. A total of 1995 (11%) of the surgically treated patients with hip fracture were excluded as a result of missing anesthesia information. The final study sample consisted of 16,695 patients. Of these, 2027 (12%) died and 98 (< 1%) terminated membership during followup, which were handled as competing events and censoring events, respectively. Ninety-day mortality, emergency department returns, hospital readmission, deep vein thrombosis (DVT) or pulmonary embolism (PE), myocardial infarction (MI), and pneumonia were evaluated using multivariable competing risk proportional subdistribution hazard regression according to type of anesthesia technique: general anesthesia, regional anesthesia, or conversion from regional to general. Of the 16,695 patients, 58% (N = 9629) received general anesthesia, 40% (N = 6597) received regional anesthesia, and 2.8% (N = 469) patients were converted from regional to general. RESULTS: Compared with regional anesthesia, patients treated with general anesthesia had a higher likelihood of overall 90-day mortality (hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.11-1.35; p < 0.001); however, when stratified by before and after hospital discharge but within 90 days of surgery, this higher risk was only observed during the inpatient stay (HR, 3.83; 95% CI, 3.18-4.61; p < 0.001); no difference was observed after hospital discharge (HR, 1.04; 95% CI, 0.94-1.16; p = 0.408). Patients undergoing conversion from regional to general also had a higher overall mortality risk compared with those undergoing regional anesthesia (HR, 1.34; 95% CI 1.04-1.74; p = 0.026), but this risk was only observed during their inpatient stay (HR, 6.84; 95% CI, 4.21-11.11; p < 0.001) when stratifying by before and after hospital discharge. Patients undergoing general anesthesia had a higher risk for all-cause readmission when compared with regional anesthesia (HR, 1.09; 95% CI, 1.01-1.19; p = 0.026). No differences according to anesthesia type were observed for risk of 90-day AHRQ outcomes, including DVT/PE, MI, and pneumonia. CONCLUSIONS: We found the use of general anesthesia and conversion from regional to general anesthesia were associated with a higher risk of mortality during the in-hospital stay compared with regional anesthetic techniques, but this higher risk did not persist after hospital discharge. We also found general anesthesia to be associated with a higher risk of all-cause readmission compared with regional, but no other differences were observed in risk for complications. Our findings suggest regional anesthetic techniques may be preferred when possible in this patient population. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID- 29601379 TI - Moderate to Severe Renal Insufficiency Is Associated With High Mortality After Hip and Knee Replacement. AB - BACKGROUND: In patients having elective hip or knee replacements, many comorbid conditions, including diabetes, cardiovascular disease, and congestive heart failure, are associated with postoperative mortality. Renal failure and a history of renal transplantation also increase mortality. However, the effect of different stages of chronic kidney disease on patients' prognoses is unclear. QUESTIONS/PURPOSES: (1) What is the risk of postoperative mortality in different stages of chronic kidney disease after elective hip or knee replacement and does the risk increase with mild renal insufficiency? (2) How severe is the risk of death in patients with chronic kidney disease compared with other major medical comorbidities such as diabetes, cardiovascular disease, and congestive heart failure? (3) Are there risk factor combinations associated with especially poor survival? METHODS: Using longitudinally maintained databases, the records of 18,575 patients (median age 69 years, 63% female, median body mass index 29 kg/m) undergoing elective hip and knee replacements from a single center between 2002 and 2011 were analyzed in this retrospective study. A total of 6519 (35%) patients had Stage I, 9917 (53%) Stage II, 2023 (11%) Stage III, 81 (0.4%) Stage IV, and 35 (0.2%) Stage V chronic kidney disease. Kaplan-Meier analysis was used to analyze mortality at different stages of the disease. Cox regression analysis was performed to compare the risk of death associated with the comorbid conditions of interest. Comorbid conditions with greatest risk for death (diabetes, coronary artery disease, and congestive heart failure) were combined separately with chronic kidney disease using logistic regression. According to data from the Finnish Population Register Centre, a total of 4055 deaths occurred in our patient cohort during the followup period. The median followup was 7.8 years (range, 0-14 years; interquartile range, 5.8-10.0 years). RESULTS: The mean survival time was 13 years (95% confidence interval [CI], 12.5-12.7 years) in Stage I, 11 years (95% CI, 11.3-11.5 years) in Stage II, 9 years (95% CI, 9.2-9.7 years) in Stage III, 7 years (95% CI, 5.6-7.5 years) in Stage IV, and 6 years (95% CI, 4.9-8.0 years) in Stage V (p < 0.001). Compared with Stage I chronic kidney disease, the risk of death increased with every step of the disease (adjusted hazard ratio [HR], 1.9 [95% CI, 1.76-2.10]; HR, 3.8 [95% CI, 3.39 4.19]; and HR, 8.1 [95% CI, 6.33-10.31] in Stages II, III, and IV-V, respectively). Compared with congestive heart failure (HR, 2.11 [95% CI, 1.81 2.45], p < 0.001), coronary disease (HR, 1.54 [95% CI, 1.40-1.69], p < 0.001), diabetes (HR, 1.71 [95% CI, 1.54-1.90], p < 0.001), and hypertension (HR, 1.35 [95% CI, 1.26-1.45], p < 0.001), Stage III and Stage IV to V chronic kidney disease are associated with poorer survival. The combination of chronic kidney disease and diabetes (odds ratio [OR], 8.15 [95% CI, 4.9-13.51]) had a synergistic effect on the risk of death compared with chronic kidney disease (OR, 2.36 [95% CI, 1.70-3.28]) or diabetes alone (OR, 1.19 [95% CI, 0.70-2.03]) during the first postoperative year. CONCLUSIONS: All stages of chronic kidney disease have a harmful effect on long-term life expectancy in joint replacement recipients. The risk becomes clinically meaningful in the most severe forms of the disease, but also in moderate chronic kidney disease when it is accompanied by diabetes, coronary disease, or congestive heart failure. It should be recognized that these patients achieve fewer quality-adjusted life-years even if clinical outcomes were similar. The effect of chronic kidney disease on cost effectiveness of hip and knee replacements should be investigated in future studies. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID- 29601380 TI - Can Genipin-coated Sutures Deliver a Collagen Crosslinking Agent to Improve Suture Pullout in Degenerated Tendon? An Ex Vivo Animal Study. AB - BACKGROUND: The suture-tendon interface is often the weakest link in tendon-to tendon or tendon-to-bone repair. Genipin is an exogenous collagen crosslink agent derived from the gardenia fruit that can enhance suture force to failure of the tendon-suture interface. Viable methods for intraoperative clinical delivery of genipin could be of clinical utility, but to our knowledge have not yet been extensively studied. QUESTIONS/PURPOSES: The purposes of this study were (1) to evaluate whether sutures precoated with genipin can augment the suture-tendon interface to improve force to failure, stiffness, and work to failure in healthy and degenerated tendons; and (2) to determine the effect of genipin on the extent and distribution of crosslinking. METHODS: Single-stitch suture pullout tests were performed ex vivo on 25 bovine superficial digital flexor tendons. To assess effects on native tissue, one group of 12 tendons was cut in proximal and distal halves and randomized to treatment (n = 12) and control groups (n = 12) in a matched-pair design. One simple stitch with a loop with either a normal suture or genipin-coated suture was applied to tendons in both groups. To simulate a degenerative tendon condition, a second group of 13 tendons was cut in proximal and distal halves, injected with 0.2 mL of collagenase D (8 mg/mL) and incubated for 24 hours before suturing with either a genipin-coated suture (n = 13) or their matched controls (n = 13). Sutures from all groups then were loaded to failure on a universal materials testing machine 24 hours after suturing. Suture pullout force, stiffness, and work to failure were calculated from force displacement data and compared between the groups. Additionally, fluorescence was measured to determine the degree of crosslinking quantitatively and a qualitative analysis of the distribution pattern was performed by microscopy. RESULTS: In healthy tendon pairs, the median maximum pullout force was greater with genipin coated sutures than with control sutures (median, 42 N [range, 24-73 N] versus 29 N [range, 13-48 N]; difference of medians, 13 N; p = 0.003) with corresponding increases in the required work to failure (median, 275 mJ [range, 48-369 mJ] versus 148 mJ [range, 83-369 mJ]; difference of medians, 127 mJ; p = 0.025) but not stiffness (median, 4.1 N/mm [range, 2.3-8.1 N/mm] versus 3.3 N/mm [range, 1.1 9.6 N/mm]; difference of medians, 0.8 N/mm; p = 0.052). In degenerated tendons, median maximum pullout force was greater with genipin-coated sutures than with control sutures (median, 16 N [range, 9-36 N] versus 13 N [range, 5-28 N]; difference of medians, 3 N; p = 0.034) with no differences in work to failure (median, 75 mJ [range, 11-249 mJ] versus 53 mJ [range, 14-143 mJ]; difference of medians, 22 mJ; p = 0.636) or stiffness (median, 1.9 N/mm [range, 0.7-13.4 N/mm] versus 1.6 N/mm [range, 0.5-5.6 N/mm]; difference of medians, 0.3 N/mm; p = 0.285). Fluorescence was higher in tendons treated with genipin-coated sutures compared with the control group, whereas higher fluorescence was observed in the treated healthy compared with the degenerated tendons (difference of means -3.16; standard error 1.08; 95% confidence interval [CI], 0.97-5.34; p = 0.006/healthy genipin: mean 13.04; standard error 0.78; 95% CI, 11.47-14.62; p < 0.001/degenerated genipin: mean 9.88; SD 0.75; 95% CI, 8.34-11.40; p < 0.001). CONCLUSIONS: Genipin-coated sutures improved force to failure of a simple stitch at the tendon-suture interface in healthy and degenerated tendons in an ex vivo animal model. Fluorescence was higher in tendons treated with genipin-coated sutures compared with the control group. CLINICAL RELEVANCE: A genipin-coated suture represents a potential delivery vehicle for exogenous crosslink agents to augment suture retention properties. In vivo animal studies are the next logical step to assess safety and efficacy of the approach. PMID- 29601381 TI - Does the Alpha-defensin Immunoassay or the Lateral Flow Test Have Better Diagnostic Value for Periprosthetic Joint Infection? A Systematic Review. AB - BACKGROUND: Measuring alpha-defensin concentrations in synovial fluid may help to diagnose periprosthetic joint infection (PJI). There are two commercially available methods for measuring alpha-defensin in synovial fluid: the enzyme linked immunosorbent assay-based Synovasure(r) alpha-defensin immunoassay, which gives a numeric readout within 24 hours, and the Synovasure lateral flow test, which gives a binary readout within 20 minutes. There is no compilation of the existing literature to support the use of one of these two tests over the other. QUESTIONS/PURPOSES: Does the immunoassay or the lateral flow test have better diagnostic value (sensitivity and specificity) in diagnosing PJI? METHODS: We followed PRISMA guidelines and identified all studies on alpha-defensin concentration in synovial fluid as a PJI diagnostic marker, indexed to April 14, 2017, in PubMed, JSTOR, Google Scholar, and OVID databases. The search retrieved 1578 records. All prospective and retrospective studies on alpha-defensin as a PJI marker (PJI classified according to the criteria of the Musculoskeletal Infection Society) after THA or TKA were included in the analysis. All studies used only one of the two commercially available test methods, but none of them was comparative. After excluding studies with overlapping patient populations, four studies investigating the alpha-defensin immunoassay and three investigating the lateral flow test remained. Alpha-defensin immunoassay studies included 482 joints and lateral flow test studies included 119. The quality of the trials was assessed according to the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. The heterogeneity among studies was evaluated by the I index, indicating that the heterogeneity of the included studies was low. Pooled sensitivity, specificity, positive and negative likelihood ratios, and receiver operating curves were calculated for each method and compared with each other. RESULTS: The alpha-defensin immunoassay had superior overall diagnostic value compared with the lateral flow test (area under the curve, 0.98 versus 0.75) with higher sensitivity (96% [90%-98%] versus 71% [55%-83%], p < 0.001), but no difference in specificity with the numbers available (96% [93%-97%] versus 90% [81%-95%], p = 0.060). CONCLUSIONS: Measurement of alpha-defensin in synovial fluid is a valuable complement to existing diagnostic criteria, and the immunoassay test detects PJI more accurately than the lateral flow test. The lateral flow test has lower sensitivity, making it difficult to rule out infection, but its relatively high specificity combined with the advantage of a quick response time can make it useful to rule in infection perioperatively.

PMID- 29601383 TI - Is Platelet-rich Plasma Injection Effective for Chronic Achilles Tendinopathy? A Meta-analysis. AB - BACKGROUND: Chronic Achilles tendinopathy is common in the general population, and platelet-rich plasma (PRP) is seeing increased use to treat this problem. However, studies disagree as to whether PRP confers a beneficial effect for chronic Achilles tendinopathy, and no one to our knowledge has pooled the available randomized trials in a formal meta-analysis to try to reconcile those differences. QUESTIONS/PURPOSES: In the setting of a systematic review and meta analysis of randomized controlled trials (RCTs), we asked: Does PRP plus eccentric strength training result in (1) greater improvements in Victorian Institute of Sports Assessment-Achilles (VISA-A) scores; (2) differences in tendon thickness; or (3) differences in color Doppler activity compared with placebo (saline) injections plus eccentric strength training in patients with chronic Achilles tendinopathy? METHODS: A search of peer-reviewed articles was conducted to identify all RCTs using PRP injection with eccentric training for chronic Achilles tendinopathy in the electronic databases of PubMed, Web of Science (SCI-E/SSCI/A&HCI), and EMBASE from January 1981 to August 2017. Results were limited to human RCTs and published in all languages. Two reviewers assessed study quality using the Cochrane Collaboration risk-of-bias tool. All the included studies had low risk of bias. The primary endpoint was improvement in the VISA-A score, which ranges from 0 to 100 points, with higher scores representing increased activity and less pain; we considered the minimum clinically important difference on the VISA-A to be 12 points. Secondary outcomes were tendon thickness change (with a thicker tendon representing more severe disease), color Doppler activity (with more activity representing a poorer result), and other functional measures (such as pain and return to sports activity). Four RCTs involving 170 participants were eligible and included 85 participants treated with PRP injection and eccentric training and 85 treated with saline injection and eccentric training. The patients in both PRP and placebo (saline) groups seemed comparable at baseline. We assessed for publication bias using a funnel plot and saw no evidence of publication bias. Based on previous studies, we had 80% power to detect a 12-point difference on the VISA-A score with the available sample size in each group. RESULTS: With the numbers available, there was no difference between the PRP and saline groups regarding the primary outcome (VISA-A score: mean difference [MD], 5.3; 95% confidence interval [CI], -0.7 to 11.3; p = 0.085). Likewise, we found no difference between the PRP and saline groups in terms of our secondary outcomes of tendon thickness change (MD, 0.2 mm; 95% CI, 0.6-1.0 mm; p = 0.663) and color Doppler activity (MD, 0.1; 95% CI, -0.7 to 0.4; p = 0.695). CONCLUSIONS: PRP injection with eccentric training did not improve VISA-A scores, reduce tendon thickness, or reduce color Doppler activity in patients with chronic Achilles tendinopathy compared with saline injection. Larger randomized trials are needed to confirm these results, but until or unless a clear benefit has been demonstrated in favor of the new treatment, we cannot recommend it for general use.

PMID- 29601384 TI - Are Age and Patient Gender Associated With Different Rates and Magnitudes of Clinical Improvement After Reverse Shoulder Arthroplasty? AB - BACKGROUND: An improved understanding of how gender differences and the natural aging process are associated with differences in clinical improvement in outcome metric scores and ROM measurements after reverse total shoulder arthroplasty (rTSA) may help physicians establish more accurate patient expectations for reducing postoperative pain and improving function. QUESTIONS/PURPOSES: (1) Is gender associated with differences in rTSA outcome scores like the Simple Shoulder Test (SST), the UCLA Shoulder score, the American Shoulder and Elbow Surgeons (ASES) Shoulder score, the Constant Shoulder score, and the Shoulder Pain and Disability Index (SPADI) and ROM? (2) Is age associated with differences in rTSA outcome scores and ROM? (3) What factors are associated with the combined interaction effect between age and gender? (4) At what time point during recovery does most clinical improvement occur, and when is full improvement reached? METHODS: We quantified and analyzed the outcomes of 660 patients (424 women and 236 men; average age, 72 +/- 8 years; range, 43-95 years) with cuff tear arthropathy or osteoarthritis and rotator cuff tear who were treated with rTSA by 13 shoulder surgeons from a longitudinally maintained international database using a linear mixed effects statistical model to evaluate the relationship between clinical improvements and gender and patient age. We used five outcome scoring metrics and four ROM assessments to evaluate clinical outcome differences. RESULTS: When controlling for age, men had better SST scores (mean difference [MD] = 1.41 points [95% confidence interval {CI}, 1.07-1.75], p < 0.001), UCLA scores (MD = 1.76 [95% CI, 1.05-2.47], p < 0.001), Constant scores (MD = 6.70 [95% CI, 4.80-8.59], p < 0.001), ASES scores (MD = 7.58 [95% CI, 5.27 9.89], p < 0.001), SPADI scores (MD = -12.78 [95% CI, -16.28 to -9.28], p < 0.001), abduction (MD = 5.79 degrees [95% CI, 2.74-8.84], p < 0.001), forward flexion (MD = 7.68 degrees [95% CI, 4.15-11.20], p < 0.001), and passive external rotation (MD = 2.81 degrees [95% CI, 0.81-4.8], p = 0.006). When controlling for gender, each 1-year increase in age was associated with an improved ASES score by 0.19 points (95% CI, 0.04-0.34, p = 0.011) and an improved SPADI score by -0.29 points (95% CI, -0.46 to 0.07, p = 0.020). However, each 1 year increase in age was associated with a mean decrease in active abduction by 0.26 degrees (95% CI, -0.46 to 0.07, p = 0.007) and a mean decrease of forward flexion by 0.39 degrees (95% CI, -0.61 to 0.16, p = 0.001). A combined interaction effect between age and gender was found only with active external rotation: in men, younger age was associated with less active external rotation and older age was associated with more active external rotation (beta0 [intercept] = 11.029, beta1 [slope for age variable] = 0.281, p = 0.009). Conversely, women achieved no difference in active external rotation after rTSA, regardless of age at the time of surgery (beta0 [intercept] = 34.135, beta1 [slope for age variable] = -0.069, p = 0.009). Finally, 80% of patients achieved full clinical improvement as defined by a plateau in their outcome metric score and 70% of patients achieved full clinical improvement as defined by a plateau in their ROM measurements by 12 months followup regardless of gender or patient age at the time of surgery with most improvement occurring in the first 6 months after rTSA. CONCLUSIONS: Gender and patient age at the time of surgery were associated with some differences in rTSA outcomes. Men had better outcome scores than did women, and older patients had better outcome scores but smaller improvements in function than did younger patients. These results demonstrate rTSA outcomes differ for men and women and for different patient ages at the time of surgery, knowledge of these differences, and also the timing of improvement plateaus in outcome metric scores and ROM measurements can both improve the effectiveness of patient counseling and better establish accurate patient expectations after rTSA.

PMID- 29601385 TI - Intratibial Injection Causes Direct Pulmonary Seeding of Osteosarcoma Cells and Is Not a Spontaneous Model of Metastasis: A Mouse Osteosarcoma Model. AB - BACKGROUND: Although metastasis is the major cause of mortality in patients with osteosarcoma, little is known about how micrometastases progress to gross metastatic disease. Clinically relevant animal models are necessary to facilitate development of new therapies to target indolent pulmonary metastases. Intratibial injection of human and murine osteosarcoma cell lines have been described as orthotopic models that develop spontaneous pulmonary metastasis over time. However, there is variability in reported injection techniques and metastatic efficiency. QUESTIONS/PURPOSES: We aimed to characterize a widely used murine model of metastatic osteosarcoma, determine whether it is appropriate to study spontaneous pulmonary metastasis by establishing a reliable volume for intratibial injection, determine the incidence of primary tumor and metastatic formation, determine the kinetics of pulmonary metastatic seeding and outgrowth, and the contribution of the primary tumor to subsequent development of metastasis. METHODS: The metastatic mouse osteosarcoma cell line K7M2 was injected into the tibia of mice. The maximum volume that could be injected without leakage was determined using Evan's blue dye (n = 8 mice). Primary tumor formation and metastatic efficiency were determined by measuring the incidence of primary tumor and metastatic formation 4 weeks after intratibial injection (n = 30). The kinetics of metastatic development were determined by performing serial euthanasia at 1, 2, 3, and 4 weeks after injection (n = 24; five to six mice per group). Number of metastatic foci/histologic lung section and metastatic burden/lung section (average surface area of metastatic lesions divided by the total surface area of the lung) was calculated in a blinded fashion. To test the contribution of the primary tumor to subsequent metastases, amputations were performed 30 minutes, 4 hours, or 24 hours after injection (n = 21; five to six mice per group). Mice were euthanized after 4 weeks and metastatic burden calculated as described previously, comparing mice that had undergone amputation with control, nonamputated mice. Differences between groups were calculated using Kruskal-Wallis and one-way analysis of variance. RESULTS: The maximum volume of cell suspension that could be injected without leakage was 10 MUL. Intratibial injection of tumor cells led to intramedullary tumor formation in 93% of mice by 4 weeks and resulted in detectable pulmonary metastases in 100% of these mice as early as 1 week post-injection. Metastatic burden increased over time (0.88% +/- 0.58, week 1; 6.6% +/- 5.3, week 2; 16.1% +/- 12.5, week 3; and 40.3% +/- 14.83, week 4) with a mean difference from week 1 to week 4 of -39.38 (p < 0.001; 95% confidence interval [CI], -57.39 to -21.37), showing pulmonary metastatic growth over time. In contrast, the mean number of metastatic foci did not increase from week 1 to week 4 (36.4 +/- 33.6 versus 49.3 +/- 26.3, p = 0.18). Amputation of the injected limb at 30 minutes, 4 hours, and 24 hours after injection did not affect pulmonary metastatic burden at 4 weeks, with amputation as early as 30 minutes post-injection resulting in a metastatic burden equivalent to tumor bearing controls (48.9% +/- 6.1% versus 40.9% +/- 15.3%, mean difference 7.96, p = 0.819; 95% CI, -33.9 to 18.0). CONCLUSIONS: There is immediate seeding of the metastatic site after intratibial injection of the K7M2 osteosarcoma cell line, independent of a primary tumor. This is therefore not a model of spontaneous metastasis. CLINICAL RELEVANCE: This model should not be used to study the early components of the metastatic cascade, but rather used as an experimental model of metastasis. Improved understanding of this commonly used model will allow for proper interpretation of existing data and inform the design of future studies exploring the biology of metastasis in osteosarcoma.

PMID- 29601401 TI - Should Emergency Department Attendances be Used With or Instead of Readmission Rates as a Performance Metric?: Comparison of Statistical Properties Using National Data. AB - BACKGROUND: Hospital readmissions are common and are viewed as unfavorable. They are commonly used as a measure of quality of care and, in the United States and England, are associated with financial penalties. Readmissions are not the only possible return-to-acute-care metric; patients may also attend emergency departments (ED). OBJECTIVE: To assess hospital-level return-to-acute-care metrics using statistical criteria. RESEARCH DESIGN: Patient readmissions and/or ED attendances were aggregated to produce risk-standardized hospital rates. Return-to-acute-care rates at 7, 30, 90, and 365 days were assessed using key statistical properties: (i) variability between hospitals; (ii) the relative contribution of patient and nonpatient factors to variation; and (iii) the statistical power to detect performance differences. SUBJECTS: We had pseudonymized administrative data on all inpatient hospital admissions and ED attendances in National Health Service hospitals in England between April 2009 and March 2011. Patients with an inpatient stay for chronic obstructive pulmonary disorder or heart failure were eligible for inclusion. MEASURES: ED attendances and readmissions for patients discharged from an inpatient stay for chronic obstructive pulmonary disorder or heart failure. RESULTS: Interhospital variation was greatest for ED attendance; in addition, readmission was more strongly determined by patient characteristics than was ED attendance or both combined. Because of smaller numbers, the statistical power to detect differences in rates at 7 days for any indicator was limited. CONCLUSIONS: Despite the current emphasis on readmissions, we found that ED attendance within 30 days has more desirable statistical properties and therefore the potential to be a useful metric when comparing hospitals. PMID- 29601402 TI - Risk Factors for Anal Dysplasia in Transgender Women: A Retrospective Chart Review. AB - OBJECTIVE: The aim of the study was to assess risk factors for anal human papillomavirus (HPV) infection and anal dysplasia among a cohort of transgender women (TGW). METHODS: A retrospective chart review was conducted based on electronic medical records of TGW patients seen in the University of Miami Health System between 2010 and 2016. Outcome measures included risk factors of anal dysplasia, including HIV infection, receptive anal intercourse, and smoking history. Descriptive statistical analysis and chi testing were used. RESULTS: Sixty-nine TGW patients' charts were reviewed. Patients' ages ranged from 18 to 72 (mean = 38 [15]). Twenty-two (30%) were older than 50 years; 10 (15%) were black/African descent; 20 (29%) reported a smoking history; 6 (9%) were HIV positive, and 28 (72%) among those with known partner preference (n = 39) reported male partners. Male partner preference was significantly associated with being black/African descent (p = .009) and being single (p = .048). Older age was significantly associated with HIV-positive status (p = .023). The average number of risk factors per person was 2.10 (0.97). Sixty-one years or older had the highest average number of risk factors (2.90 [0.88]). CONCLUSIONS: Because rates of HIV, dangerous sexual behaviors, and other risk factors for anal dysplasia continue to persist among TGW, this study reinforces the need to increase the focus on anal health in the care of TGW and the need for further research to guide patient care and anal dysplasia screening strategies among those individuals. PMID- 29601403 TI - Brief Report: Differential Timing of Cholesterol Increase During Successful HCV Therapy: Impact of Type of Drug Combination. AB - OBJECTIVE: To evaluate factors associated with increased serum cholesterol levels during interferon-free hepatitis C virus (HCV) therapy. DESIGN: Prospective longitudinal study. METHODS: HIV-infected patients who started and successfully completed interferon-free therapy for chronic HCV infection were included. Patients were treated using 2 different regimens, based on the clinician's opinion: sofosbuvir and ledipasvir (SOF/LDV), or paritaprevir coadministered with ombitasvir and dasabuvir (PrOD). Both total cholesterol and low-density lipoprotein cholesterol were evaluated at baseline, weeks 1, 2, 4, 8, end of treatment (EOT), weeks SVR4, SVR12, and SVR24. RESULTS: The study population therefore comprised 85 patients reaching sustained virological response, 42 (49.4%) of whom were treated with SOF/LDV, and 43 (50.6%) with PrOD. Patients using SOF/LDV was showed a higher increase on both total cholesterol and low density lipoprotein cholesterol during treatment period than those receiving PrOD. Analyzing the overall increase from baseline to weeks 1, 2, 4, 8, and EOT, choice of HCV regimen was associated with differential increases in total cholesterol during therapy. After EOT, no differences were found between SOF/LDV and PrOD with respect to total cholesterol. CONCLUSIONS: Our study suggests that the differential timing of the restoration of cholesterol metabolism in HIV/HCV genotype 1 coinfected patients achieving sustained virological response is not mediated by HCV clearance but depends on the drug combination used.

PMID- 29601405 TI - High-Risk Prescription Opioid Use Among People Living With HIV. AB - BACKGROUND: Prescription opioid use is greater among people living with HIV (PLWH), yet little is known about the prevalence of specific types of high-risk use among these individuals. SETTING: We analyzed clinical and demographic data from the HIV Research Network and prescribing data from Medicaid for noncancer patients seeking HIV treatment at 4 urban clinics between 2006 and 2010. METHODS: HIV Research Network patients were included in the analytic sample if they received at least one incident opioid prescription. We examined 4 measures of high-risk opioid use: (1) high daily dosage; (2) early refills; (3) overlapping prescriptions; and (4) multiple prescribers. RESULTS: Of 4605 eligible PLWH, 1814 (39.4%) received at least one incident opioid prescription during follow-up. The sample was 61% men and 62% African American with a median age of 44.5 years. High risk opioid use occurred among 30% of incident opioid users (high daily dosage: 7.9%; early refills: 15.9%; overlapping prescriptions: 16.4%; and multiple prescribers: 19.7%). About half of the cumulative incidence of high-risk use occurred within 1 year of receiving an opioid prescription. After adjusting for study site, high-risk opioid use was greater among patients with injection drug use as an HIV risk factor [adjusted hazard ratio (aHR) = 1.39, 95% confidence interval: 1.11 to 1.74], non-Hispanic whites [aHR = 1.61, (1.21 to 2.14)], patients age 35-45 [aHR = 1.94, (1.33 to 2.80)] and 45-55 [aHR = 1.84, (1.27 to 2.67)], and patients with a diagnosis of chronic pain [aHR = 1.32, (1.03 to 1.70)]. CONCLUSIONS: A large proportion of PLWH received opioid prescriptions, and among these opioid recipients, high-risk opioid use was common. High-risk use patterns often occurred within the first year, suggesting this is a critical time for intervention. PMID- 29601406 TI - Sex Differences in Subclinical Coronary Atherosclerotic Plaque Among Individuals With HIV on Antiretroviral Therapy. AB - BACKGROUND: In high-resource settings, the HIV-attributable risk of myocardial infarction (MI) is higher among women than among men. The extent to which unique mechanisms contribute to MI risk among women vs. men with HIV remains unclear. METHODS: Subclinical coronary atherosclerotic plaque characteristics-including high-risk morphology plaque features-were compared among 48 HIV-infected women [48 (41, 54) years] and 97 HIV-infected men [48 (42, 52) years] on stable antiretroviral therapy (ART) without known cardiovascular disease. These individuals had previously completed coronary computed tomography angiography and metabolic/immune phenotyping as part of a prospective study. RESULTS: Extending previous analyses, now focusing exclusively on ART-treated participants, we found that HIV-infected women had a lower prevalence of any subclinical coronary atherosclerotic plaque (35% vs. 62%, P = 0.003) and a lower number of segments with plaque (P = 0.01), compared with HIV-infected men. We also report for the first time that ART-treated HIV-infected women had a lower prevalence of high risk positively remodeled plaque (25% vs. 51%, P = 0.003) and a lower number of positively remodeled plaque segments (P = 0.002). In models adjusting for cardiovascular risk factors, we further showed that male sex remained associated with any coronary plaque [odds ratio 3.8, 95% confidence interval: (1.4 to 11.4)] and with positively remodeled plaque [odds ratio 3.7, 95% confidence interval: (1.4, 10.9)]. CONCLUSIONS: ART-treated HIV-infected women (vs. HIV-infected men) had a lower prevalence and burden of subclinical coronary plaque and high-risk morphology plaque. Thus, unique sex-specific mechanisms beyond subclinical plaque may drive the higher HIV-attributable risk of MI among women vs. men. PMID- 29601407 TI - Effect of Valproate and Antidepressant Drugs on Clozapine Metabolism in Patients With Psychotic Mood Disorders. AB - BACKGROUND: The aim of the present study was to appraise retrospectively the influence of valproate (VPA) and antidepressants (ADs) on the steady-state plasma concentrations of clozapine (CLZ), the prototype of various second-generation antipsychotics, norclozapine (NCLZ, its main metabolite), and their ratio (NCLZ:CLZ). METHODS: Sixty-seven psychotic patients with a prevalent diagnosis of bipolar disorder were studied. We then analyzed data altogether and subdivided them into 4 groups, according to pharmacological treatments: #1 CLZ (n = 21), #2 CLZ plus ADs (n = 13), #3 CLZ plus VPA (n = 16), and #4 CLZ plus ADs plus VPA (n = 17). RESULTS: First, significant positive between CLZ and NCLZ plasma levels (in nanograms/milliliter) and the drug daily dosages (in milligrams/kilogram of body weight) (n = 67) were observed (Spearman: rCLZ = 0.49; rNCLZ = 0.61; P < 0.001). We then normalized by given doses CLZ and NCLZ plasma levels, natural log transformed them, and performed analysis of variance factor analyses followed by pairwise comparisons, performed on the 4 groups and the 3 CLZ parameters. We identified significant drug effects on (1) CLZ plasma levels, significantly higher in group #2 versus group #1, and (2) NCLZ:CLZ ratio, lower in group #2 versus groups #1 and #3. Significant drug * gender interactions were observed in group #3, showing higher NCLZ levels and NCLZ:CLZ ratios in men compared with women. CONCLUSIONS: Despite its inherent limitations, this observational study confirms the significant increase in plasma CLZ concentrations and reduction in NCLZ:CLZ ratio when this drug was coadministered with ADs (group #2), an effect apparently counteracted by VPA (group #4). The drug * gender interactions in patients taking both CLZ and VPA (group #3) warrant further prospective study. PMID- 29601408 TI - Microanatomical Nerve Architecture of 6 Mammalian Species: Is Trans-Species Translational Anatomic Extrapolation Valid? AB - BACKGROUND AND OBJECTIVES: Various animal models have historically been used to study iatrogenic nerve injury during performance of conduction nerve blocks. Our aims were to compare the microstructures of nerves in commonly used species to those of humans and to explore the validity of the extrapolating these findings to humans. METHODS: High-resolution, light-microscopic images were obtained from cross sections of sciatic nerves at their bifurcation from fresh rat, rabbit, pig, sheep, dog, and human cadavers. Various microanatomical characteristics were measured and compared between the species. P < 0.0033 indicated significant differences. RESULTS: Forty-four samples were studied. There were some interspecies similarities, but the majority of the microanatomical measurements of all 5 species differed significantly from those of humans. Exceptions were rat fascicle cross-sectional area (P = 0.367) and fascicle circumference (P = 0.396); ratio of dog, pig, and sheep fascicle area to total nerve area (dog: P = 0.350; pig: P = 0.958; sheep: P = 0.052); and number of fascicles (pig: P = 0.454; sheep P = 0.077). CONCLUSIONS: Although some of the metrics could reasonably be expected to differ because of the size of the species-for example, nerve cross sectional area-there was little microanatomical similarity between the sciatic nerves of humans and those of the nonprimate mammalian species studied. This may question the validity of some conclusions reached over the years by direct translation from these species to humans. Further studies on nerve function, intraneural injection, and microanatomy of nonhuman primate species are warranted. PMID- 29601409 TI - Correlation of MRI-derived adipose tissue measurements and anthropometric markers with prevalent hypertension in the community. AB - OBJECTIVES: To compare the correlations of MRI-derived adipose tissue measurements and anthropometric markers, respectively, with prevalent hypertension in a community-based sample, free of clinical cardiovascular disease. METHODS: MRI-derived adipose tissue measurements were obtained in 345 participants (143 women; age 39-73 years) of the KORA FF4 survey from Southern Germany using a 3-Tesla machine and included total adipose tissue (TAT), visceral adipose tissue (VAT), subcutaneous adipose tissue (SCAT), hepatic fat fraction (HFF), pancreatic fat fraction (PFF) as well as pericardial adipose tissue (PAT). In addition, the anthropometric markers body mass index, waist circumference, hip circumference, waist-hip ratio (WHR) and waist-height ratio (WHtR) as well as blood pressure measurements were obtained. RESULTS: The prevalence of hypertension was 33.6% (women: 28%, men: 38%). VAT and PAT had the highest area under the curve (AUC) values for identifying individuals with prevalent hypertension (AUC: 0.75; 0.73, respectively), whereas WHtR and waist circumference were best performing anthropometric markers (AUC: 0.72; 0.70, respectively). A 1SD increment of TAT was associated with the highest odd for hypertension in the age-adjusted and sex-adjusted model (OR = 2.20, 95% CI 1.67 2.91, P < 0.001) and in the fully adjusted model (OR = 1.97, 95% CI 1.45-2.66, P < 0.001). TAT was the only MRI-derived adipose tissue measurement that was associated with hypertension independently of the best performing anthropometric marker waist circumference in the fully adjusted model (OR = 1.93, 95% CI 1.00 3.72, P = 0.049). CONCLUSION: MRI-derived adipose tissue measurements perform similarly in identifying prevalent hypertension compared with anthropometric markers. Especially, TAT, VAT and PAT as well as WHtR and waist circumference were highly correlated with prevalent hypertension. PMID- 29601410 TI - Increased aortic wave reflection contributes to higher systolic blood pressure in adolescents born preterm. AB - OBJECTIVE: To evaluate the wave reflection characteristics in the aortic arch and common carotid artery of ex-preterm adolescents and assess their relationship to central blood pressure in a cohort followed prospectively since birth. METHODS: Central blood pressures, pulse wave velocity, augmentation index, microvascular reactive hyperemia, arterial distensibility, compliance and stiffness index, and also aortic and carotid wave intensity were measured in 18-year-olds born extremely preterm at below 28 weeks' gestation (n = 76) and term-born controls (n = 42). RESULTS: Compared with controls, ex-preterm adolescents had higher central systolic (111 +/- 11 vs. 105 +/- 10 mmHg; P < 0.001) and diastolic blood pressures (73 +/- 7 vs. 67 +/- 7 mmHg; P < 0.001). Although conventional measures of arterial function and biomechanics such as pulse wave velocity and augmentation index were no different between groups, wave intensity analysis revealed elevated backward compression wave area (-0.39 +/- 0.21 vs. -0.29 +/- 0.17 W/m/s * 10; P = 0.03), backward compression wave pressure change (9.0 +/- 3.5 vs. 6.6 +/- 2.5 mmHg; P = 0.001) and reflection index (0.44 +/- 0.15 vs. 0.32 +/- 0.08; P < 0.001) in the aorta of ex-preterm adolescents compared with controls. These changes were less pronounced in the carotid artery. On multivariable analysis, forward and backward compression wave areas were the only biomechanical variables associated with central systolic pressure. CONCLUSIONS: Ex-preterm adolescents demonstrate elevated wave reflection indices in the aortic arch, which correlate with central systolic pressure. Wave intensity analysis may provide a sensitive novel marker of evolving vascular dysfunction in ex-preterm survivors. PMID- 29601411 TI - Antihypertensive drug use in resistant and nonresistant hypertension and in controlled and uncontrolled resistant hypertension. AB - BACKGROUND AND AIM: Treatment-resistant hypertension (TRH) is associated with particular clinical features, nonadherence, and suboptimal treatment. We assessed possible associations of antihypertensive drug classes, specific agents inside each class, and types of combinations, with the presence of non-TRH vs. TRH, and with controlled vs. uncontrolled TRH. METHODS: Comparisons were done in 14 264 patients treated with three drugs (non-TRH: 2988; TRH: 11 276) and in 6974 treated with at least four drugs (controlled TRH: 1383; uncontrolled TRH: 5591). Associations were adjusted for age, sex, and previous cardiovascular event. RESULTS: In both groups of patients treated with three or with at least four drugs, aldosterone antagonists among drug classes [adjusted odds ratio (OR): 1.82 and 1.41, respectively], and ramipril (OR: 1.28 and 1.30), olmesartan (OR: 1.31 and 1.37), and amlodipine (OR: 1.11 and 1.41) inside each class were significantly associated with blood pressure control (non-TRH or controlled TRH). In patients treated with three drugs, non-TRH was also associated with the use of chlorthalidone (OR: 1.50) and bisoprolol (OR: 1.19), whereas in patients treated with at least four drugs, controlled TRH was significantly associated with the triple combination of a renin-angiotensin system blocker, a calcium channel blocker, and a diuretic (OR: 1.17). CONCLUSION: The use of aldosterone antagonists is associated with blood pressure control in patients treated with three or more drugs. Similar results are observed with specific agents inside each class, being ramipril, olmesartan, chlorthalidone, amlodipine, and bisoprolol those exhibiting significant results. An increased use of these drugs might probably reduce the burden of TRH. PMID- 29601412 TI - Left ventricular mass independently associates with masked hypertension in young healthy adults: the African-PREDICT study. AB - OBJECTIVE: Masked hypertension is reportedly common in young adults. However, it is unknown if these masked hypertensive individuals already present with organ damage. We determined whether a relationship exists between left ventricular structure and function, and masked hypertension in young healthy adults. METHODS: In this cross-sectional study, we included 774 black and white men and women (aged 20-30 years) who had successful ambulatory blood pressure monitoring readings (>70% valid readings) and valid echocardiography done. RESULTS: We found that 16.4% had masked hypertension (60.6% whites; 67.7% men). When performing multivariable-adjusted logistic regression, we found masked hypertensive patients to have higher odds to present with increased left ventricular mass index (odds ratio 1.67, P = 0.031) compared to normotensive individuals. In multivariable adjusted linear regression analyses, left ventricular mass index positively and independently associated with masked hypertension [adjusted R = 0.193, beta = 0.08 (0.01; 0.16), P = 0.046]. However, we found no independent link between echocardiographic measures of left ventricular function and masked hypertension. CONCLUSION: This study highlights the importance of the early detection of masked hypertension as young apparently healthy adults already show an increased left ventricular mass index, thereby indicating increased risk for future cardiovascular disease. PMID- 29601413 TI - Masked hypertension and kidney function decline: the Jackson Heart Study. AB - BACKGROUND: Hypertension diagnosed by blood pressure (BP) measured in the clinic is associated with rapid kidney function decline (RKFD) and incident chronic kidney disease (CKD). The extent to which hypertension defined using out-of clinic BP measurements is associated with these outcomes is unclear. METHODS: We evaluated the association of any masked hypertension (daytime SBP/DBP >= 135/85 mmHg, night-time SBP/DBP >= 120/70 mmHg or 24-h SBP/DBP >= 130/80 mmHg) with RKFD and incident CKD among 676 African-Americans in the Jackson Heart Study with clinic-measured SBP/DBP less than 140/90 mmHg who completed ambulatory BP monitoring in 2000-2004. RKFD was defined as a decline in estimated glomerular filtration rate (eGFR) at least 30% and incident CKD was defined as development of eGFR less than 60 ml/min per 1.73 m with an at least 25% decline in eGFR between 2000-2004 and 2009-2013. RESULTS: The mean age of participants was 57.6 years, 28.8% were men and 52.7% had any masked hypertension. After a median follow-up of 8 years, 13.8 and 8.6% of participants had RKFD and incident CKD, respectively. In unadjusted analyses, masked hypertension was associated with an increased odds for incident CKD [odds ratio (OR) 2.20, 95% confidence interval (CI) 1.22, 3.97]. This association remained statistically significant after adjustment for demographic characteristics, baseline eGFR and albumin-to creatinine ratio (OR 1.95, 95% CI 1.04, 3.67) but was eliminated after propensity score adjustment (OR 1.62, 95% CI 0.87, 3.00). There was no association between masked hypertension and RKFD. CONCLUSION: Masked hypertension may be associated with the development of CKD in African-Americans.

PMID- 29601414 TI - Feeling Safe and Taking on Responsibilities: Newly Graduated Nurses' Perceptions and Evaluations of Their Transition Into a Forensic Mental Health Inpatient Setting. AB - Forensic mental health care is faced with serious problems in the recruitment and retention of newly graduated nurses (NGNs). Research into NGNs' experiences of their transition to and evaluations of transition programs in forensic care is sparse, and more studies are called for. This study aimed to investigate the characteristics of NGNs' experiences and perceptions of their transition into a forensic setting and their evaluations of the introduction period. Three focus group interviews were carried out, involving 13 NGNs, lasting 79.68 minutes on average. They were analyzed using thematic analysis. Results show two main themes: "feeling safe" and "taking on responsibilities." If NGNs felt overburdened with clinical responsibilities during their transition, their feeling of safety reduced. The converse also applied; theThe safer they felt, the greater clinical responsibility they felt capable of handling. The more difficult the NGNs perceived the informal transition, the more unsafe they felt, and the more negatively they perceived the responsibilities placed upon them. Tailored programs designed to support both the informal and formal transitions are recommended, along with preceptorship, theoretical training, and role-based support, such as a shift manager, along with early introduction to conflict management and security measures.

Case management practice is always evolving on the basis of the dynamic nature of the U.S. health care environment. Effective case managers are those who possess an adaptive mind set, recognize the importance to change to maintain success, and remain relevant. They also demonstrate a sense of accountability and responsibility for own learning, professional development, and acquisition of new skills and knowledge. This editorial discusses the nature of change and adaptation and presents key strategies for case managers to remain relevant and effective in dynamic practice environments. PMID- 29601423 TI - Managing the Social Determinants of Health: Part I: Fundamental Knowledge for Professional Case Management. AB - OBJECTIVES: PRIMARY PRACTICE SETTING(S):: Applicable to health and behavioral health settings, wherever case management is practiced. FINDING/CONCLUSION: The SDH pose major challenges to the health care workforce in terms of effective resource provision, health and behavioral health treatment planning plus adherence, and overall coordination of care. Obstacles and variances to needed interventions easily lead to less than optimal outcomes for case managers and their health care organizations. Possessing sound knowledge and clear understanding of each SDH, the historical perspectives, main theories, and integral dynamics, as well as creative resource solutions, all support a higher level of intentional and effective professional case management practice. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Those persons and communities impacted most by the SDH comprise every case management practice setting. These clients can be among the most vulnerable and disenfranchised members of society, which can easily engender biases on the part of the interprofessional workforce. They are also among the costliest to care for with 50% of costs for only 5% of the population. Critical attention to knowledge about managing the SDH leverages and informs case management practice, evolves more effective programming, and enhances operational outcomes across practice settings. PMID- 29601424 TI - An Acuity Tool for Heart Failure Case Management: Quantifying Workload, Service Utilization, and Disease Severity. AB - PURPOSE: The cardiology service line director at a health maintenance organization (HMO) in Washington State required a valid, reliable, and practical means for measuring workloads and other productivity factors for six heart failure (HF) registered nurse case managers located across three geographical regions. The Kilgore Heart Failure Case Management (KHFCM) Acuity Tool was systematically designed, developed, and validated to measure workload as a dependent function of the number of heart failure case management (HFCM) services rendered and the duration of times spent on various care duties. PRIMARY PRACTICE SETTING: Research and development occurred at various HMO-affiliated internal medicine and cardiology offices throughout Western Washington. The concepts, methods, and principles used to develop the KHFCM Acuity Tool are applicable for any type of health care professional aiming to quantify workload using a high quality objective tool. The content matter, scaling, and language on the KHFCM Acuity Tool are specific to HFCM settings. METHODOLOGY AND SAMPLE: The content matter and numeric scales for the KHFCM Acuity Tool were developed and validated using a mixed-method participant action research method applied to a group of six outpatient HF case managers and their respective caseloads. The participant action research method was selected, because the application of this method requires research participants to become directly involved in the diagnosis of research problems, the planning and execution of actions taken to address those problems, and the implementation of progressive strategies throughout the course of the study, as necessary, to produce the most credible and practical practice improvements (; ; ; ). Heart failure case managers served clients with New York Heart Association Functional Class III-IV HF (), and encounters were conducted primarily by telephone or in-office consultation. RESULTS: A mix of qualitative and quantitative results demonstrated a variety of quality improvement outcomes achieved by the design and practice application of the KHFCM Acuity Tool. Quality improvement outcomes included a more valid reflection of encounter times and demonstration of the KHFCM Acuity Tool as a reliable, practical, credible, and satisfying tool for reflecting HF case manager workloads and HF disease severity. IMPLICATIONS: The KHFCM Acuity Tool defines workload simply as a function of the number of HFCM services performed and the duration of time spent on a client encounter. The design of the tool facilitates the measure of workload, service utilization, and HF disease characteristics, independently from the overall measure of acuity, so that differences in individual case manager practice, as well as client characteristics within sites, across sites, and potentially throughout annual seasons, can be demonstrated. Data produced from long-term applications of the KHFCM Acuity Tool, across all regions, could serve as a driver for establishing systemwide HFCM productivity benchmarks or standards of practice for HF case managers. Data produced from localized applications could serve as a reference for coordinating staffing resources or developing HFCM productivity benchmarks within individual regions or sites. PMID- 29601425 TI - Predicting Risk Factors for 30-Day Readmissions Following Discharge From Post Acute Care. AB - PURPOSE OF STUDY: The specific aims of this descriptive study were to (1) examine the relationships between individual-level determinants of health using standard care admission assessments of residents admitted to a skilled nursing facility (SNF) and those residents readmitted to the hospital within 30 days from discharge from the same SNF; (2) identify and describe the risk factors of the residents readmitted to the hospital within 30 days; and (3) use the findings to inform and refine current practice to target the mutable risk factors correlated with 30-day hospital readmission. PRIMARY PRACTICE SETTING: A 180-bed skilled nursing center in Northeastern Pennsylvania. METHODOLOGY AND SAMPLE: A retrospective paper medical record review of patients discharged from an SNF to community living was conducted to examine the relationship between individual determinants of health behaviors and 30-day hospital readmissions. The study sample (N = 221) included adults 65 years and older who were admitted to the SNF from January to December 2014 for subacute physical rehabilitation following an acute care hospital stay with a discharge plan to community living. RESULTS: The 30-day readmission rate was 11%. The results of the logistic regression including diagnosis at readmission showed that the odds of readmission before 30 days were nearly three times greater in patients who had congestive heart failure (p < .02). Patients who were at "very high risk" on the Braden Scale were 20 times more likely to be readmitted before 30 days compared with those at low risk. Age and gender were not predictors. None of the other standard screening assessments for delirium, depression, functional status, and fall risk were predictive of 30 day readmission. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: (1) Care coordination and communication with residents, caregivers, and home health can have an impact on 30-day readmissions post-SNF discharge. (2) Chronic respiratory diseases continue to be a challenge in prevention of hospital readmissions. PMID- 29601426 TI - The Integrated Case Management Program: Essential for Today's Case Manager.

PMID- 29601433 TI - Thiopurine Optimization Through Combination With Allopurinol in Children With Inflammatory Bowel Diseases. AB - OBJECTIVES: Thiopurines are commonly used in the maintenance of remission for children with inflammatory bowel diseases (IBDs). Variation in drug metabolism may affect hepatotoxicity or therapeutic effect. We aimed to describe our center's experience with thiopurine optimization through the use of reduced thiopurine dosing in combination with allopurinol upon hepatotoxicity, drug metabolite levels, and clinical outcomes in children with IBD. METHODS: Patients aged 2 to 21 years with IBD treated with the combination of thiopurines/allopurinol between 2008 and 2015 were retrospectively reviewed. Patients previously treated with antitumor necrosis factor therapy were excluded. Demographic data, transaminase levels (aspartate transaminase, alanine transaminase), drug metabolites levels (6-thioguanine [6-TG], 6 methylmercaptopurine), physician global assessment, and corticosteroid use were recorded at baseline, 6, and 12 months. RESULTS: Fifty-two patients (29 girls, 56%) met inclusion criteria. Thirty-two of 52 (62%) remained on the combination for 12 months. In those remaining on the thiopurine/allopurinol combination, median alanine transaminase and aspartate transaminase levels were reduced (P < 0.001) and median 6-TG levels were increased (P < 0.001) at both 6 and 12 months. Corticosteroid use was decreased at both 6 (P < 0.001) and 12 months (P < 0.001) compared to use at baseline. Remission rates also improved at both 6 (P = 0.013) and 12 months (P = 0.003). Twenty of the 52 patients (38%) had discontinued the thiopurine/allopurinol combination within 12 months of initiation with 17 of 52 (33%) initiating antitumor necrosis factor therapy. CONCLUSIONS: Low-dose thiopurines in combination with allopurinol improved hepatotoxicity and increased 6-TG levels in children with IBD. Corticosteroid use was reduced and remission rates improved in those patients remaining on this combination for 1 year. However, approximately 40% of patients required a change in therapy within 12 months. PMID- 29601434 TI - Pediatric Collagenous Gastritis and Colitis: A Case Series and Review of the Literature. AB - INTRODUCTION: Collagenous gastritis is a rare disease characterized by the subepithelial deposition of collagen bands. Two phenotypes of the disease have been described: a pediatric-onset and an adult-onset type. The adult-onset form is associated with collagenous colitis and autoimmune disorders. No effective treatment has been identified to date. OBJECTIVE: We aim to describe the clinical features and outcomes of patients in our cohort and provide a summary of published pediatric cases with collagenous gastritis and colitis reported to date to gather information that will contribute to improved knowledge of this rare condition. METHODS: A retrospective chart review of all patients with collagenous gastritis and/or colitis who were treated at the Royal Children's Hospital, Melbourne, was performed. A literature review was also conducted. RESULTS: A total of 12 cases of collagenous gastritis were reviewed. Three of 12 (25%) patients had associated collagenous colitis. The most common clinical presentation was iron deficiency anemia. Nine (75%) patients were followed up, and repeat endoscopies were performed in 8 (67%). Iron deficiency anemia resolved in all patients on oral iron supplementation. Histologic improvement was only identified in one patient with the adult phenotype who had been treated with oral corticosteroids and azathioprine. CONCLUSIONS: Collagenous gastritis is a rare condition in children. A small proportion of children develop features of the "'adult" phenotype at a very young age. Patients with collagenous gastritis require long-term follow-up and monitoring of their disease. Further randomized clinical trials are needed to establish an effective therapeutic strategy. PMID- 29601435 TI - Multivariate Model for the Prediction of Severity of Acute Pancreatitis in Children. AB - This study aimed to develop a severity prediction system for pediatric patients with acute pancreatitis (AP) based on clinical and laboratory parameters recorded at disease onset. A retrospective cohort study including 130 patients with AP, aged 0 to 18 years, was conducted. Correlations between severe AP (SAP) and clinical and laboratory data were established. Parameters with a significant statistical correlation (P <= 0.05) were incorporated in logistic regression models, and receiver operating characteristic curves were generated. The best performance cutoff points were calculated to propose a severity prediction score, for which sensitivity and specificity were determined. Thirty-eight cases (29.2%) were consistent with SAP. A value of >=1 point yielded a sensitivity of 81.5% and specificity of 64.1% for SAP prediction, when using a score including blood urea nitrogen >=12.5 mg/dL (1 point) or hemoglobin <13 mg/dL (1 point) as variables. The proposed severity score showed good performance in predicting SAP. PMID- 29601436 TI - Gavage Feed Volume Determines the Gastric Emptying Rate in Preterm Infants. AB - OBJECTIVE: Feeding intolerance, manifesting as increased gastric residual, is a common finding in preterm neonates. Little is known about the regulation of gastric emptying early in life and the extent to which this plays a role in the preterm infants' feeding tolerance. The goal of this study was to evaluate clinically stable 28- to 32-week gestation neonates during the first 4 weeks of life and noninvasively determine their gastric emptying rate. STUDY DESIGN: Ultrasound measurements of gastric milk content volume were obtained from 25 neonates immediately after, 30 and/or 60 minutes following routine gavage feeds. The content emptying rate was calculated from the gastric volume data. RESULTS: Gastric emptying rate was not postnatal age-dependent, was significantly higher at 30 minutes, whenever compared with 60-minute postfeed and directly proportional to the feed volume. At any postnatal age, the gastric emptying rate was at least 6-fold greater, when comparing the lowest and highest average stomach content volumes. CONCLUSIONS: The gastric emptying rate of preterm infants is content volume-dependent and unrelated to the postnatal age. Given the present findings, further investigation on the gastric residual of preterm infants receiving larger than currently administered feed volumes at the initiation of enteral nutrition, is warranted. PMID- 29601437 TI - Detection of Cytomegalovirus in Colonic Mucosa of Children With Inflammatory Bowel Disease: Inflammatory Bowel Disease. AB - OBJECTIVES: Although it has been recommended to perform sigmoidoscopy to screen for cytomegalovirus (CMV) reactivation in acute severe colitis, the frequency of CMV reactivation in children with inflammatory bowel disease (IBD) is unknown. The aim of this study was to determine the frequency and management of CMV detection in colonic mucosa of children with IBD. METHODS: In a retrospective study, consecutive IBD patients, <17 years old, with moderate to severe colitis who had sigmoid biopsy specimens evaluated for CMV by hematoxylin and eosin (H&E) staining, immunohistochemistry (IHC), and polymerase chain reaction (PCR) were included. RESULTS: A total of 90 sigmoid biopsies were collected from 67 patient encounters from 58 patients with colitis: 61 patient encounters (91%) with UC/IBD U including biopsy samples from colectomy specimens of eight patients who had colectomy during the study period. Medication exposure included corticosteroids for 40 (69%) patients, and immunosuppressive agents for 31 (53.4%) patients. Four of 61 patient encounters (6.6%) with UC/IBD-U, two with corticosteroid refractory disease, had positive biopsies for CMV by PCR but negative H&E and IHC. They responded to escalated medical therapy, without needing anti-viral therapy, and none required colectomy over a median duration of follow up of 1.1 year (IQR 1 1.6). CONCLUSIONS: CMV presence is uncommon in colonic mucosa of children with IBD. Studies examining the underlying sero-prevalence of CMV and its role of reactivation of colitis are required to determine if the current recommendation for routine sigmoidoscopy to exclude CMV infection in corticosteroid-refractory acute severe colitis is justified. PMID- 29601438 TI - Proton Pump Inhibitors and Infant Pneumonia/Other Lower Respiratory Tract Infections: National Nested Case-control Study. AB - OBJECTIVE: The possible association between the use of proton pump inhibitors (PPIs) and community-acquired pneumonia (CAP) or another lower respiratory tract infection (LRTI) remains uncertain. We conducted a nested case-control study using routinely collected national health and drug dispensing data in New Zealand to examine the risk of CAP or another LRTI resulting in hospitalization or death in infants dispensed a PPI. STUDY DESIGN: The cohort included 21,991 patients without a history of CAP or another LRTI who were born between 1 January 2005 and 31 December 2012 and were dispensed omeprazole, lansoprazole, or pantoprazole (the PPIs available in New Zealand during the study period) on at least one occasion during the first year of life. Cases had a first diagnosis after cohort entry (first PPI dispensing) of CAP (n = 65) validated by hospital discharge letter or death record, and chest radiography; or LRTI (including CAP) (n = 566) validated by hospital discharge letter or death record, with or without chest radiography. Up to 10 controls, matched by sex and date of birth, were randomly selected for each case. We conducted complete case analyses for the fully adjusted models. RESULTS: In the adjusted analysis based on CAP cases and their controls, the matched odds ratio for current versus past use of PPIs was 0.88 (95% confidence interval 0.36-2.16). For all LRTI cases and their controls, the matched odds ratio was 1.13 (0.87-1.48). CONCLUSION: In otherwise healthy community-dwelling infants, current use of a PPI does not appear to increase the risk of CAP or other LRTIs. PMID- 29601439 TI - Neurodevelopmental Outcomes in Children With Liver Diseases: a Systematic Review. AB - OBJECTIVE: The aim of the study was to determine the neurodevelopmental outcomes of children with liver diseases based on a systematical review of the literature. METHOD: A literature search according to the PRISMA statement was conducted using predefined search terms in PubMed, Cochrane Library, and PsycINFO. The inclusion criterion was studies published from 2000 onwards that reported on the neurodevelopmental outcomes of term-born children with liver diseases. A narrative synthesis was done to appraise the studies. RESULTS: Twenty-five studies were included (1913 children), 19 of which described children after liver transplantation (LTx; 1372 children). Sixty-seven percentage of the studies on children with liver diseases who survived with their native livers showed low average or abnormal scores on specific subscales of cognitive and behavioral measures. In studies on children after LTx, this was 82%. After LTx, 83% of studies demonstrated impaired outcomes on behavior, whereas 42% of children received special education. Motor development was impaired in 82% of studies in children with native liver and after LTx. LIMITATIONS: Studies were heterogenic because of sample sizes, etiology of liver disease and type of assessment tools used. CONCLUSIONS: More than two-third of included studies showed neurodevelopmental deficits in children with liver diseases, affecting all neurodevelopmental areas. Knowledge on risk factors for impaired neurodevelopment is limited and lack of long-term follow-up is worrying, especially considering the increasing survival rates, resulting in more at-risk patients. Studying early predictors and risk factors of abnormal developmental trajectories of children with liver diseases is indicated to assess strategies to improve their long-term neurodevelopmental outcomes. PMID- 29601440 TI - Celiac Diasease-associated lncRNA Named HCG14 Regulates NOD1 Expression in Intestinal Cells. AB - OBJECTIVE: The aim of the study is to identify additional celiac disease associated loci in the major histocompatibility complex (MHC) independent from classical HLA risk alleles (HLA-DR3-DQ2) and to characterize their potential functional impact in celiac disease pathogenesis at the intestinal level. METHODS: We performed a high-resolution single-nucleotide polymorphism (SNP) genotyping of the MHC region, comparing HLA-DR3 homozygous celiac patients and non-celiac controls carrying a single copy of the B8-DR3-DQ2 conserved extended haplotype. Expression level of potential novel risk genes was determined by RT PCR in intestinal biopsies and in intestinal and immune cells isolated from control and celiac individuals. Small interfering RNA-driven silencing of selected genes was performed in the intestinal cell line T84. RESULTS: MHC genotyping revealed 2 associated SNPs, one located in TRIM27 gene and another in the non-coding gene HCG14. After stratification analysis, only HCG14 showed significant association independent from HLA-DR-DQ loci. Expression of HCG14 was slightly downregulated in epithelial cells isolated from duodenal biopsies of celiac patients, and eQTL analysis revealed that polymorphisms in HCG14 region were associated with decreased NOD1 expression in duodenal intestinal cells. CONCLUSIONS: We have successfully employed a conserved extended haplotype matching strategy and identified a novel additional celiac disease risk variant in the lncRNA HCG14. This lncRNA seems to regulate the expression of NOD1 in an allele-specific manner. Further functional studies are needed to clarify the role of HCG14 in the regulation of gene expression and to determine the molecular mechanisms by which the risk variant in HCG14 contributes to celiac disease pathogenesis. PMID- 29601441 TI - The Membrane-bound O-Acyltransferase7 rs641738 Variant in Pediatric Nonalcoholic Fatty Liver Disease. AB - BACKGROUND: The rs641738 polymorphism in the membrane-bound O-acyltransferase domain containing protein 7 (MBOAT7) gene has been associated with increased risk of nonalcoholic fatty liver disease (NAFLD). OBJECTIVES: To investigate the association between the MBOAT7 rs641738 polymorphism and both hepatic steatosis and biochemical markers of liver damage and to evaluate the potential additive effect of this variant and the I148M patatin-like phospholipase domain-containing 3 (PNPLA3) and the rs58542926 transmembrane 6 superfamily member 2 (TM6SF2) polymorphisms. METHODS: One thousand and 2 obese children were genotyped for MBOAT7, PNPLA3, and TM6SF2 polymorphisms and underwent anthropometrical, ultrasonographic, and biochemical evaluation. Indirect measurement of liver fibrosis (Pediatric NAFLD Fibrosis Index [PNFI]) and a genetic risk score from these polymorphisms were calculated. RESULTS: Carriers of the MBOAT7 T allele showed both higher alanine transaminase (ALT) (P = 0.004) and PNFI values (P = 0.04) than noncarriers. These findings were confirmed also for the carriers of the MBOAT7 T allele polymorphism with hepatic steatosis compared with noncarriers. A higher genetic risk score was associated with higher ALT (P = 0.011) and with an odds ratio (OR) to show elevated ALT of 3.4 (95% CI 1.3-5.5, P = 0.003). Patients belonging to genetic risk score 3 group had an OR to present steatosis of 2.6 (95% CI 1.43-4.83, P = 0.0018) compared with those belonging to lower genetic risk score group. CONCLUSIONS: We first demonstrated in childhood obesity the role of the MBOAT7 rs641738 variant on serum ALT and the combined effect of the MBOAT7, PNPLA3, and TM6SF2 variants on NAFLD risk. We also provided the first pediatric association of the MBOAT7 polymorphism with indirect markers of liver fibrosis.

PMID- 29601443 TI - Yield and Examiner Dependence of Digital Rectal Examination in Detecting Impaction in Pediatric Functional Constipation. AB - OBJECTIVES: Guidelines on functional constipation recommend digital rectal examination (DRE) when constipation is doubtful or with a suspicion of organic etiology. The guidelines do not clarify if DRE is mandatory to diagnose impaction. This study aims to determine the frequency of impaction detectable only on DRE among children satisfying Rome III criteria without requiring DRE and also the inter-observer influences on impaction detection by DRE. METHODS: Children between 6 months to 13 years of age, presenting with history suggestive of constipation were assessed. After excluding those with suspicion of organic etiology, those who needed DRE for diagnosis of constipation and those who do not satisfy Rome III criteria without DRE, the rest who satisfied Rome III criteria were assessed for impaction by palpable fecoliths or constipation-associated fecal incontinence. Those without such impaction were randomized to 2 examiners for DRE to diagnose impaction, in the absence of contraindications. RESULTS: Two hundred and thirty-three children were assessed. One hundred and sixty-nine satisfied Rome III without needing DRE. Forty-eight (28.4%) had impaction detectable without DRE. Among the rest, 28 (30.1%) had impaction by DRE. There was no difference between the frequency of impaction detected by the 2 examiners. Clinical characteristics were similar (P > 0.05) between those with impaction detectable by DRE and those without. CONCLUSIONS: DRE does detect cases of impaction not discernible by other means. Such a finding may be comparable between examiners. These children may be identified by other clinical characteristics. The clinical significance of such a finding needs more understanding from the standpoint of therapeutic choices. PMID- 29601444 TI - Tribute to the unknown nurse.

PMID- 29601446 TI - Analysis of Treatment Outcomes for Recurrent Clostridium difficile Infections and Fecal Microbiota Transplantation in a Pediatric Hospital. AB - BACKGROUND: Clostridium difficile infection (CDI) is one of the most common nosocomial infections in the United States, with an increasing incidence in children. Approximately 20% of pediatric patients develop recurrent infections. It's imperative to further analyze the incidence of recurrent CDI in the pediatric population and determine the most effective treatments. The primary goal of this study is to characterize children with recurrent CDI at our institution, including both hospital-acquired (HA-CDI) and community-acquired (CA CDI) cases, summarize the various treatments utilized, including fecal microbiota transplant (FMT), and compare their success rates. METHODS: A retrospective cohort study of pediatric patients aged 1-21 years treated for CDI at a single institution from January 2010 - December 2014 was performed. RESULTS: There were 175 subjects with 215 separate episodes of CDI. Oral metronidazole was the most common initial treatment (145/207, 70%) followed by oral vancomycin (30/207, 15%), with recurrence rates of 30% (42/145) and 37% (11/30), respectively. Twenty nine percent (63/215) of all initial CDI cases had at least one documented recurrence. Using multivariate analysis, subjects with HA-CDI were 2.6 times less likely to recur than those with CA-CDI (OR: 0.39; 95% CI: 0.18-0.85; p=0.018). The overall success rate for FMT at our institution was 10/12 (83%). CONCLUSIONS: Our data show cases of HA-CDI were less likely to recur compared with CA-CDI. Though currently reserved for multiply-recurrent cases, FMT was highly successful in our small cohort. More studies on FMT should be conducted to further evaluate its usefulness in the treatment of recurrent CDI in children. PMID- 29601447 TI - Itraconazole Dosing and Drug Monitoring at a Tertiary Children's Hospital. AB - BACKGROUND: Itraconazole is a broad-spectrum antifungal agent used for prophylaxis and treatment of fungal infections in immunocompromised children. Achieving the recommended target serum itraconazole trough concentration of >=0.5 mg/L is challenging in children due to variation in itraconazole pharmacokinetics with age. We studied itraconazole use and treatment outcomes in a tertiary children's hospital. METHODS: We did a ten-year retrospective review of medical records of children at the Royal Children's Hospital Melbourne who received oral itraconazole and had therapeutic drug monitoring (TDM). RESULTS: Overall, 81 children received 92 courses of oral itraconazole and had TDM. Of 222 TDM samples, 183 (82.4%) were taken at the appropriate time (trough level at steady state). Patients aged <=12 years and >12 years required median doses of 6.2 and 3.9 mg/kg/day respectively to attain target trough levels(p<0.001). Of children aged <=12 years, 71.4% required doses above the recommended dose of 5 mg/kg/day to achieve therapeutic levels, compared to 17.4% of those aged >12 years. At least one sub-therapeutic trough concentration was reported in 63 (76.8%) courses; in only 18 (28.6%) of these was the dose adjusted. Gastrointestinal symptoms (14/92 (15.2%) courses) and hepatotoxicity (6/92 (6.5%)) were the most frequent adverse events. Neither were associated with elevated trough levels. CONCLUSIONS: The poor attainment of target levels with current recommended dosing in children aged <12 years suggests higher empiric doses are needed in this age group. The poor compliance with TDM guidelines highlights the need for better education about appropriate timing of sampling and dose adjustment. PMID- 29601448 TI - Antibiotic Overuse in Children with Respiratory Syncytial Virus Lower Respiratory Tract Infection. AB - BACKGROUND: Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infections (LRTI) during the first year of life. Antibiotic treatment is recommended in cases suspected of bacterial coinfection. The aim of this prospective study was to estimate the incidence of bacterial coinfections and the amount of antibiotic overuse in children infected with RSV using expert panel diagnosis. METHODS: Children 1 month of age and over with LRTI or fever without source were prospectively recruited in hospitals in the Netherlands and Israel. Children with confirmed RSV infection by Polymerase Chain Reaction (PCR) on nasal swabs were evaluated by an expert panel as reference standard diagnosis. Three experienced pediatricians distinguished bacterial coinfection from simple viral infection using all available clinical information, including all microbiologic evaluations and a 28-day follow-up evaluation. RESULTS: A total of 188 children (24% of all 784 recruited patients) were positive for RSV. From these, 92 (49%) were treated with antibiotics. All 27 children (29%) with bacterial coinfection were treated with antibiotics. Fifty-seven patients (62%) were treated with antibiotics without a diagnosis of bacterial coinfection. In 8 of the 92 (9%), the expert panel could not distinguish simple viral infection from bacterial coinfection. CONCLUSION: This is the first prospective international multicenter RSV study using an expert panel as reference standard to identify children with and without bacterial coinfection. All cases of bacterial coinfections are treated, whereas as many as one-third of all children with RSV LRTI are treated unnecessarily with antibiotics. PMID- 29601449 TI - Antifungal Treatment and Outcome in Very Low Birth Weight Infants: A Population based Observational Study of the German Neonatal Network. AB - BACKGROUND: The diagnostic proof of fungal infection in preterm infants is difficult. Antifungal treatment (AFT) is often initiated empirically when infants with suspected infection do not improve despite broad-spectrum antibiotic therapy. It was the aim of our study to determine the rate of exposure to empirical AFT in a large cohort of very low birth weight infants (VLBWI) of the German Neonatal Network and to address associated risks and outcomes. METHODS: The epidemiologic database consisted of n = 13,343 VLBWI born in 54 German Neonatal Network centers between 2009 and 2015. AFT was defined as number of neonates who got any dose of at least one of the following antifungal drugs: fluconazole, amphotericin B, voriconazole and caspofungin (denominator: number of infants enrolled in German Neonatal Network) for treatment (not prophylaxis) of (suspected) fungal infection. Univariate and logistic regression analyses were used to identify risk factors for exposure to AFT and associated short-term morbidities and long-term outcomes at 5-year follow-up. RESULTS: In our cohort, 724 out of 13,343 (5.4%) VLBWI were exposed to empiric AFT and had a mean gestational age of 25.7 (+/-2.1) weeks. Forty-four out of 13,343 (0.3%) had proven bloodstream infection with Candida spp. The main risk factors for exposure to AFT were gestational age, postnatal steroid treatment, need for abdominal surgery and use of carbapenems. Notably, AFT was associated with adverse outcomes such as bronchopulmonary dysplasia [adjusted odds ratio (OR): 1.9; 95% confidence interval (CI): 1.6-2.3; P < 0.001) and retinopathy of prematurity requiring intervention (adjusted OR: 1.69; 95% CI: 1.3-2.3; P <0.001) but not mortality. In the subgroup of infants available for 5-year follow-up (n = 895), exposure to AFT was associated with a risk for cerebral palsy (adjusted OR: 2.79; 95% CI: 1.11 7.04; P = 0.04) and intelligence quotient < 85 (adjusted OR: 2.07; 95% CI: 1.01 4.28; P = 0.049). CONCLUSIONS: A significant proportion of VLBWI is exposed to AFT, specifically those born <26 weeks. Exposed infants were found to have a higher risk for adverse outcomes, which may reflect their significant vulnerability in general. Given the observational design of our study, it remains unclear whether potential side effects of empirical or target AFT itself contribute to adverse outcome. Future studies need to include risk-based strategies and stewardship programs to restrict the use of antifungal management in VLBWI.

AB - The role of Campylobacter concisus as a cause of acute gastroenteritis remains to be demonstrated. This prospective study includes 184 cases and 176 controls. It shows no evidence that C. concisus plays a role in acute gastroenteritis. Considering the very low prevalence in cases and controls, if there is an etiologic link, it would be moderate and difficult to demonstrate. PMID- 29601451 TI - Serum Levels of Syndecan-1 in Patients with Kawasaki Disease. AB - BACKGROUND: Kawasaki disease (KD) is an acute systemic vasculitis with coronary artery lesions (CALs) being the major concern. Syndecan-1 (SDC-1) is a major core protein expressed on the glycocalyx of endothelial cells. Shed SDC-1 in serum is regarded as a biomarker for endothelial activation or damage. METHODS: In this study, we aimed to determine the serum levels of SDC-1 and evaluate the relationship between serum levels of SDC-1 and the CALs in the acute phase of KD. Serum SDC-1 levels were measured in 119 children with KD and in 43 healthy children as normal controls and in 40 children with febrile disease. All KD patients were administrated a single dose of intravenous immunoglobulin (IVIG) and aspirin P.O. within 10 days of KD onset. RESULTS: Serum levels of SDC-1, in addition to albumin and hemoglobin were significantly increased in patients with KD than in healthy controls and febrile controls. Furthermore, the serum levels of syndecan-1, albumin, and hemoglobin were significantly elevated in KD patients with CALs than those without CALs. Additionally, serum levels of SDC-1 were significantly correlated with levels of hemoglobin and serum albumin in patients with KD. After IVIG therapy, serum levels of interleukin (IL)-6, soluble cell adhesion molecules-1(sICAM-1), and resisitin were reduced while serum levels of SDC-1 were significantly increased in KD patients. CONCLUSION: SDC-1 serum levels may mirror vascular endothelial damage and inflammation in KD. This might be utilized as a potential novel target for coronary artery protection in KD patients. PMID- 29601452 TI - Hospital Acquired Infections in Children: A Latin American Tertiary Teaching Hospital 5-Year Experience. AB - Hospital acquired infections account for high mortality rates and hospital costs. We analyzed pediatric data from a tertiary teaching hospital and found that most of cases occurred in the intensive care unit and had significant association with invasive devices. Bloodstream infections were the main site of infection and Gram negative bacteria were the predominant etiology.

AB - Micafungin is used off-label in the United States to treat invasive candidiasis in neonates. We used an established pharmacokinetic model to determine micafungin exposures for 46 courses in 39 hospitalized infants. In this small cohort of infants, micafungin exposure was not associated with laboratory markers of liver toxicity, death, or failure of microbiological clearance. PMID- 29601454 TI - Bacterial Load and Molecular Markers Associated With Early-onset Group B Streptococcus: A Systematic Review and Meta-analysis. AB - BACKGROUND: The natural history of neonatal group B Streptococcus (GBS) is poorly understood. Little is known about the bacterial factors influencing the transmission of GBS from mother to neonate, or the development of invasive early onset GBS disease (EOGBS) in colonized neonates. We reviewed whether bacterial load and molecular markers are associated with GBS vertical transmission and progression to EOGBS. METHODS: We searched Medline, Embase, Cochrane and Web of Science from inception to October 10, 2016, for observational studies in English. We also hand-searched reference lists of relevant publications and experts cross checked included studies. Two reviewers independently screened studies, extracted data and appraised the quality of included studies using the Quality in Prognosis Studies tool. We conducted random-effects meta-analyses where possible and narratively synthesized the evidence in text and tables. RESULTS: Seventeen studies were included from 1107 records retrieved from electronic databases and publication references. Meta-analyses of 3 studies showed that neonates colonized by serotype III had a higher risk of developing EOGBS than serotype Ia (pooled risk ratio: 1.51, 95% confidence interval: 1.12-2.03) and serotype II (risk ratio: 1.95, 95% confidence interval: 1.10-3.45). Eleven studies showed that in heavily colonized mothers, 2-3 times more neonates were colonized, and in heavily colonized neonates, up to 15 times more neonates had EOGBS, compared with light colonization. Most evidence was published before 2000 and was at risk of bias. CONCLUSIONS: Acknowledging the difficulty of natural history studies, well controlled studies are needed to assess the predictive value of pathogen subtype and heavy load; they may be useful for better-targeted prevention.

PMID- 29601456 TI - Infant Human Immunodeficiency Virus-free Survival in the Era of Universal Antiretroviral Therapy for Pregnant and Breastfeeding Women: A Community-based Cohort Study From Rural Zambia. AB - BACKGROUND: Lifelong antiretroviral therapy (ART) is now recommended for all human immunodeficiency virus (HIV)-infected pregnant and breastfeeding women; however, few have described overall infant outcomes in this new era for the prevention of mother-to-child HIV transmission (PMTCT). METHODS: As part of an assessment of PMTCT program impact, we enrolled a prospective cohort study in 4 predominantly rural districts in Zambia. HIV-infected mothers and their newborns (<=30 days old) were recruited and followed at 6 weeks, 6 months and 12 months postpartum; infant specimens were tested via HIV DNA polymerase chain reaction. In Kaplan-Meier analyses, we estimated overall infant HIV-free survival and then stratified by district, community and maternal ART use. We investigated the relationship between community-level 12-month, self-reported maternal ART use and infant HIV-free survival via linear regression. RESULTS: From June 2014 to November 2015, we enrolled 827 mother-infant pairs in 33 communities. At 12 months, small proportions of infants had died (2.8%), were HIV-infected (3.0%) or were lost to follow-up (4.3%). Overall, infant HIV-free survival was 99.0% [95% confidence interval (CI): 98.0%-99.5%] at 6 weeks, 97.5% (95% CI: 96.1%-98.4%) at 6 months and 96.3% (95% CI: 94.8%-97.4%) at 12 months. Women reporting ART use at enrollment had higher infant HIV-free survival than those who did not (97.4% vs. 89.0%, P = 0.01). Differences were noted at the district and site levels (P = 0.01). In community-level analysis, no relationship was observed between 12-month infant HIV-free survival and self-reported maternal ART use (P = 0.65). CONCLUSION: Although encouraging, these findings highlight the need for rigorous monitoring and evaluation of PMTCT services at the population level. PMID- 29601457 TI - Longitudinal Association Between Human Parechovirus Central Nervous System Infection And Gross-motor Neurodevelopment in Young Children. AB - BACKGROUND: A paucity of studies investigated the association between human parechovirus (HPeV) central nervous system (CNS) infection and motor and neurocognitive development of children. This study describes the gross-motor function (GMF) in young children during 24 months after HPeV-CNS-infection compared with children in whom no pathogen was detected. METHODS: GMF of children was assessed with alberta infant motor scale, bayley scales of infant and toddler development or movement assessment battery for children. We conducted multivariate analyses and adjusted for age at onset, maternal education and time from infection. RESULTS: Of 91 included children, aged at onset <24 months, 11 had HPeV-CNS-infection and in 47 no pathogen was detected. Nineteen children were excluded due to the presence of other infection, preterm birth or genetic disorder and in 14 children parents refused to consent for participation. We found no longitudinal association between HPeV-CNS-infection and GMF (beta = 0.53; 95%CI =-1.18 to 0.07; P = 0.11). At 6 months, children with HPeV-CNS infection had suspect GMF delay compared with the non-pathogen group (mean difference = 1.12; 95%CI =-1.96 to -0.30; P = 0.03). This difference disappeared during 24 months follow-up and, after adjustment for age at onset, both groups scored within the normal range for age. Maternal education and time from infection did not have any meaningful influence. CONCLUSION: We found no longitudinal association between HPeV-CNS-infection and GMF during the first 24 months follow-up. Children with HPeV-CNS-infection showed a suspect GMF delay at 6 months follow-up. This normalized during 24 month follow-up. PMID- 29601458 TI - Epidemiology and Clinical Relevance of Toxic Shock Syndrome in US Children. AB - INTRODUCTION: It is important for clinicians to recognize the contribution of toxic shock syndrome (TSS) to the overall burden of pediatric septic shock because the clinical features, optimal therapy and prognosis differ from non-TSS septic shock. METHODS: We analyzed cases of pediatric septic shock reported to the Pediatric Health Information Systems database between 2009 and 2013 to define the clinical and demographic characteristics of pediatric TSS in the United States. Using a validated International Classification of Diseases, 9th revision, coding strategy, we identified patients with infectious shock among inpatients age 1-18 years and classified cases of staphylococcal and streptococcal TSS for comparison with non-TSS cases. RESULTS: Of 8,226 cases of pediatric septic shock, 909 (11.1%) were classified as TSS and 562 (6.8%) were possible TSS cases. Staphylococcal TSS represented the majority (83%) of TSS cases and occurred more commonly in females and at an older age. Compared with non-TSS septic shock, TSS had significantly lower fatality rates, disease severity and length of hospital stay and was present more often at the time of admission (P < 0.001 for each). Streptococcal TSS was associated with poorer outcomes than staphylococcal TSS. Treatment for TSS differed from non-TSS septic shock in use of more clindamycin, vancomycin and Intravenous Immunoglobulin and less need for vasopressors. CONCLUSIONS: Results demonstrate a significant contribution of TSS to the burden of pediatric septic shock in the United States. The findings emphasize the importance of inclusion of TSS diagnostic and therapeutic considerations in sepsis treatment protocols for children. PMID- 29601459 TI - Simplified Treatment of Possible Severe Bacterial Infection in Young Infants When Referral is not Feasible. What Happened There? What are the Implications Here? AB - Severe bacterial infections remain one of the three leading causes of newborn death world-wide. Most such deaths could be prevented with timely and appropriate antibiotic treatment. However in low-income countries, there are many such cases for which, practically speaking, it is not currently feasible to offer gold standard, in-patient treatment with 7 days of parenteral antibiotics. Recent trial results, however, provide evidence for efficacy using simpler out-patient antibiotic regimens, equivalent to treatment with 7 days of procaine penicillin and gentamicin, given on an outpatient basis. Based on these findings, the World Health Organization has recently released guidelines endorsing such an approach for cases for which referral for inpatient treatment is not feasible. This brief report looks beyond the measured effect sizes in the published trials to other details on how they were implemented and what outcomes were observed for different groups of study participants. The report considers, further, the circumstances in country settings where such a strategy may be appropriate and offers issues for consideration by policy makers. PMID- 29601460 TI - National Incidence of Pediatric Mastoiditis in the United States, 2000-2012: Creating a Baseline for Public Health Surveillance. AB - Between 2000-2012, the national estimated incidence rate of pediatric mastoiditis, a rare but serious complication of acute otitis media (AOM), was highest in 2006 (2.7 per 100,000 population) and lowest in 2012 (1.8 per 100,000 population). This measure provides a baseline for public health surveillance in the pneumococcal conjugate vaccine era as stewardship efforts target antibiotic use in AOM. PMID- 29601461 TI - Pediatric Forefoot Fractures: Assessment of Fracture Patterns and Predictors of Complicated Outcome. AB - BACKGROUND: Forefoot fractures account for 6% to 10% of fractures in children, and although the majority heals with supportive treatment, complications may lead to pain and disability. No previous study in children has evaluated complication risk in the emergency department based on initial assessment characteristics. STUDY OBJECTIVES: The study aim was to identify the radiological and clinical variables that increase the complication rate of pediatric forefoot fractures. This may help emergency physicians refer patients who require more thorough follow-up or surgical intervention. METHODS: We evaluated 497 forefoot fractures on initial presentation to a pediatric emergency department at the Children's Hospital at London Health Science Centre over a 6-year period. We collected variables such as degree of angulation, displacement, number of concurrent fractures, and demographic data such as age and sex. We then determined the variables associated with complications by reviewing each patient's chart. RESULTS: Overall, there was a 6.4% complication rate. Analysis identified sex as an important predictor of complications. Females, although representing approximately one third of the sample, represented nearly two thirds of the cases with complicated outcomes (P = 0.001; odds ratio [OR], 4.67). Increased number of fractures was also significant (P = 0.01; OR, 2.41) as was increasing age (P = 0.01; OR, 1.17) and patients who chose to return to the emergency department (P < 0.05; OR, 5.282). Lateral angulation/displacement and anteroposterior angulation/displacement were not associated with increased complications. CONCLUSION: Identifying features, such as female sex, increasing age, multiple fractures, and return to emergency departments for repeat visits, may help guide the emergency physician on whom to refer for specialized care. PMID- 29601462 TI - Incident Reporting to Improve Patient Safety: The Effects of Process Variance on Pediatric Patient Safety in the Emergency Department. AB - OBJECTIVE: Medical errors threaten patient safety, especially in the pediatric emergency department (ED) where overcrowding, multiple handoffs, and workflow interruptions are common. Errors related to process variance involve situations that are not consistent with standard ED operations or routine patient care. SETTING/PARTICIPANTS: We performed a planned subanalysis of the Pediatric Emergency Care Applied Research Network incident reporting data classified as process variance events. Confidential deidentified incident reports (IRs) were collected and classified by 2 independent investigators. Events categorized as process variance were then subtyped for severity and contributing factors. Data were analyzed using descriptive statistics. OUTCOME MEASURES: The study intention was to describe and measure reported medical errors related to process variance in 17 EDs in the Pediatric Emergency Care Applied Research Network from 2007 to 2008. RESULTS: Between July 2007 and June 2008, 2906 eligible reports were reviewed. Process variance events were identified in 15.4% (447/2906). The majority were related to patient flow (35.4%), handoff communication (17.2%), and patient identification errors (15.9%). Most staff involved included nurses (47.9%) and physicians (28%); trainees were infrequently reported. The majority of events did not result in harm (65.7%); 17.9% (80/447) of cases were classified as unsafe conditions but did not reach the patient. Temporary harm requiring further treatment or hospitalization was reported in 5.6% (25/447). No events resulted in permanent harm, near death, or death. Contributing factors included human factors (92.1%), in particular handoff communication, interpersonal skills, and compliance with established procedures, and system-level errors (18.1%), including unclear or unavailable policies and inadequate staffing levels. CONCLUSIONS: Although process variance events accounted for approximately 1 in 6 reported safety events, very few led to patient harm. Because human and system level factors contributed to most of these events, our data provide an insight into potential areas for further investigation and improvements to mitigate errors in the ED setting.

AB - Clival fracture is a rare and serious injury, which mostly results in the death of the victim before reaching the hospital. The entity is hardly diagnosed in the early phase because of high mortality rates and deficiencies in completion of radiological imaging. The incidence of diagnoses increased year by year after the usage of computed tomography gained widespread availability. In this article, we aimed to present radiological and clinical characteristics of a 5-year-old patient brought to the emergency department after a motor vehicle accident. The most current recommendations with regard to the management of clival fracture of a pediatric patient are also discussed. PMID- 29601467 TI - Posttraumatic High-Flow Nonischemic Priapism. AB - Priapism is an uncommon disorder, and nonischemic priapism is seen less frequently in children, generally after trauma. Although it seems to be an advantage that urgent intervention is not required because of no cavernous ischemia, it is likely to be misdiagnosed because of the asymptomatic potential. We aimed to present a case of posttraumatic nonischemic priapism. PMID- 29601468 TI - The Use of Picture Cards to Elicit Postgraduate Dental Student Feedback. AB - The aim of this study was to elicit information about the use of picture cards to stimulate student feedback following a postgraduate dental course. Twenty-nine general dental practitioners (GDPs) volunteered for the study. Following an explanation of how this style of feedback worked, students were asked to choose a picture card from those available and use that image to stimulate their feedback. An independent interviewer introduced the topic and gathered comments in the form of qualitative data, generated by pre-formed questions. 93% (n = 26) questionnaires were completed and returned. 77% (n = 20) GDPs reported enjoying giving their feedback by 'picture card' technique; 83% (n = 20) reported this form of feedback stimulated their thoughts. Qualitative data were analysed thematically. Some GDPs felt the picture cards helped them formulate their feedback, others felt being able to give feedback to a third party they did not know was beneficial and giving feedback as a group was helpful. This novel approach of using picture cards to stimulate feedback was well received by these GDPs. A mixed result as to the value of this style of feedback was evident. A group feedback session facilitated by a stranger was considered to be a valuable approach to take. PMID- 29601470 TI - Influence of Intestinal Microbiota Transplantation and NleH Expression on Citrobacter rodentium Colonization of Mice. AB - The intestinal microbiota plays an important role in regulating host resistance to enteric pathogens. The relative abundance of the microbiota is dependent upon both genetic and environmental factors. The attaching and effacing pathogens enteropathogenic Escherichia coli, enterohemorrhagic E. coli, and Citrobacter rodentium cause diarrheal disease and translocate type III secretion system effector proteins into host cells to inhibit pro-inflammatory host responses. Here we determined the influence of both the intestinal microbiota and the expression of the C. rodentium NleH effector on C. rodentium colonization in different mouse models. We performed fecal transplantation experiments between C57BL/6J and C57BL/10ScNJ mice and found that such microbiota transfers altered both the host resistance to C. rodentium infection as well as the benefit or detriment of expressing NleH to C. rodentium intestinal colonization. PMID- 29601471 TI - Nanopulse Stimulation (NPS) Induces Tumor Ablation and Immunity in Orthotopic 4T1 Mouse Breast Cancer: A Review. AB - Nanopulse Stimulation (NPS) eliminates mouse and rat tumor types in several different animal models. NPS induces protective, vaccine-like effects after ablation of orthotopic rat N1-S1 hepatocellular carcinoma. Here we review some general concepts of NPS in the context of studies with mouse metastatic 4T1 mammary cancer showing that the postablation, vaccine-like effect is initiated by dynamic, multilayered immune mechanisms. NPS eliminates primary 4T1 tumors by inducing immunogenic, caspase-independent programmed cell death (PCD). With lower electric fields, like those peripheral to the primary treatment zone, NPS can activate dendritic cells (DCs). The activation of DCs by dead/dying cells leads to increases in memory effector and central memory T-lymphocytes in the blood and spleen. NPS also eliminates immunosuppressive cells in the tumor microenvironment and blood. Finally, NPS treatment of 4T1 breast cancer exhibits an abscopal effect and largely prevents spontaneous metastases to distant organs. NPS with fast rise-fall times and pulse durations near the plasma membrane charging time constant, which exhibits transient, high-frequency components (1/time = Hz), induce responses from mitochondria, endoplasmic reticulum, and nucleus. Such effects may be responsible for release of danger-associated molecular patterns, including ATP, calreticulin, and high mobility group box 1 (HMBG1) from 4T1-Luc cells to induce immunogenic cell death (ICD). This likely leads to immunity and the vaccine-like response. In this way, NPS acts as a unique onco-immunotherapy providing distinct therapeutic advantages showing possible clinical utility for breast cancers as well as for other malignancies. PMID- 29601469 TI - Antibiotic Use in Agriculture and Its Consequential Resistance in Environmental Sources: Potential Public Health Implications. AB - Due to the increased demand of animal protein in developing countries, intensive farming is instigated, which results in antibiotic residues in animal-derived products, and eventually, antibiotic resistance. Antibiotic resistance is of great public health concern because the antibiotic-resistant bacteria associated with the animals may be pathogenic to humans, easily transmitted to humans via food chains, and widely disseminated in the environment via animal wastes. These may cause complicated, untreatable, and prolonged infections in humans, leading to higher healthcare cost and sometimes death. In the said countries, antibiotic resistance is so complex and difficult, due to irrational use of antibiotics both in the clinical and agriculture settings, low socioeconomic status, poor sanitation and hygienic status, as well as that zoonotic bacterial pathogens are not regularly cultured, and their resistance to commonly used antibiotics are scarcely investigated (poor surveillance systems). The challenges that follow are of local, national, regional, and international dimensions, as there are no geographic boundaries to impede the spread of antibiotic resistance. In addition, the information assembled in this study through a thorough review of published findings, emphasized the presence of antibiotics in animal-derived products and the phenomenon of multidrug resistance in environmental samples. This therefore calls for strengthening of regulations that direct antibiotic manufacture, distribution, dispensing, and prescription, hence fostering antibiotic stewardship. Joint collaboration across the world with international bodies is needed to assist the developing countries to implement good surveillance of antibiotic use and antibiotic resistance. PMID- 29601472 TI - Association between Short-Term Exposure to Air Pollution and Dyslipidemias among Type 2 Diabetic Patients in Northwest China: A Population-Based Study. AB - Air pollution exposure may play an adverse role in diabetes. However, little data are available directly evaluating the effects of air pollution exposure in blood lipids of which dysfunction has been linked to diabetes or its complications. We aimed to evaluate the association between air pollution and lipids level among type 2 diabetic patients in Northwest China. We performed a population-based study of 3912 type 2 diabetes patients in an ongoing cohort study in China. Both spline and multiple linear regressions analysis were used to examine the association between short-term exposure to PM10, SO2, NO2 and total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C). By spline analyses, we observed that the relationship between SO2 and HDL-C and LDL-C was shown to be non-linear (p_non lin-association = 0.0162 and 0.000). An inverted U-shaped non-linear relationship between NO2 and LDL-C was found (p_non-lin-association < 0.0001). A J-shaped non linear relationship between PM10 and TC, HDL-C (p_non-lin-association = 0.0173, 0.0367) was also revealed. In linear regression analyses, a 10 MUg/m3 increment in SO2 was associated with 1.31% (95% CI: 0.40-2.12%), 3.52% (95% CI: 1.07-6.03%) and 7.53% (95% CI: 5.98-9.09%) increase in TC, TG and LDL-C, respectively. A 10 MUg/m3 increment in PM10 was associated with 0.45% (95% CI: 0.08-0.82%), 0.29% (95% CI: 0.10-0.49%) and 0.83% (95% CI: 0.21-1.45%) increase in TC, HDL-C and LDL C, respectively. For NO2, an increment of 10 MUg/m3 was statistically associated with -3.55% (95% CI: -6.40-0.61%) and 39.01% (95% CI: 31.43-47.03%) increase in HDL-C and LDL-C. The adverse effects of air pollutants on lipid levels were greater in female and elder people. Further, we found SO2 and NO2 played a more evident role in lipid levels in warm season, while PM10 appeared stronger in cold season. The findings suggest that exposure to air pollution has adverse effects on lipid levels among type 2 diabetes patients, and vulnerable people may pay more attention on severe air pollution days. PMID- 29601473 TI - Honey Bee Antiviral Immune Barriers as Affected by Multiple Stress Factors: A Novel Paradigm to Interpret Colony Health Decline and Collapse. AB - Any attempt to outline a logical framework in which to interpret the honey bee health decline and its contribution to elevated colony losses should recognize the importance of the multifactorial nature of the responsible syndrome and provide a functional model as a basis for defining and testing working hypotheses. We propose that covert infections by deformed wing virus (DWV) represent a sword of Damocles permanently threatening the survival of honey bee colonies and suggest that any factor affecting the honey bee’s antiviral defenses can turn this pathogen into a killer. Here we discuss the available experimental evidence in the framework of a model based on honey bee immune competence as affected by multiple stress factors that is proposed as a conceptual tool for analyzing bee mortality and its underlying mechanisms. PMID- 29601475 TI - Effects of Drought on Nutrient Uptake and the Levels of Nutrient-Uptake Proteins in Roots of Drought-Sensitive and -Tolerant Grasses. AB - Climate change will increase drought in many regions of the world. Besides decreasing productivity, drought also decreases the concentration (%) of nitrogen (N) and phosphorous (P) in plants. We investigated if decreases in nutrient status during drought are correlated with decreases in levels of nutrient-uptake proteins in roots, which has not been quantified. Drought-sensitive (Hordeum vulgare, Zea mays) and -tolerant grasses (Andropogon gerardii) were harvested at mid and late drought, when we measured biomass, plant %N and P, root N- and P uptake rates, and concentrations of major nutrient-uptake proteins in roots (NRT1 for NO3, AMT1 for NH4, and PHT1 for P). Drought reduced %N and P, indicating that it reduced nutrient acquisition more than growth. Decreases in P uptake with drought were correlated with decreases in both concentration and activity of P uptake proteins, but decreases in N uptake were weakly correlated with levels of N-uptake proteins. Nutrient-uptake proteins per gram root decreased despite increases per gram total protein, because of the larger decreases in total protein per gram. Thus, drought-related decreases in nutrient concentration, especially %P, were likely caused, at least partly, by decreases in the concentration of root nutrient-uptake proteins in both drought-sensitive and tolerant species.

To determine the functions of these proteins in large animals, we investigated their effects on the proliferation of intestinal epithelial cells from pigs. Our results indicated that LGR5 and BMI1 are highly conserved proteins and that the pig proteins have greater homology with the human proteins than do mouse proteins. Overexpression of either LGR5 or BMI1 promoted cell proliferation and WNT/beta-catenin signaling in pig intestinal epithelial cells (IPEC-J2). Moreover, the activation of WNT/beta-catenin signaling by recombinant human WNT3A protein increased cell proliferation and LGR5 and BMI1 protein levels. Conversely, inhibition of WNT/beta-catenin signaling using XAV939 reduced cell proliferation and LGR5 and BMI1 protein levels. This is the first report that LGR5 and BMI1 can increase proliferation of pig intestinal epithelial cells by activating WNT/beta-catenin signaling.

AB - Intercellular RNA trafficking has been shown as a widely-existing phenomenon that has significant functions in many aspects of biology. Viroids, circular noncoding RNAs that cause plant diseases, have been a model to dissect the role of RNA structural motifs in regulating intercellular RNA trafficking in plants. Recent studies on potato spindle tuber viroid (PSTVd) showed that the RNA motif loop 19 is important for PSTVd to spread from palisade to spongy mesophyll in infected leaves. Here, we performed saturated mutational analysis to uncover all possible functional variants of loop 19 and exploit this data to pinpoint to a three dimensional structural model of this motif. Interestingly, we found that two distinct structural motifs can replace loop 19 and retain the systemic trafficking capacity. One of the alternative structures rapidly emerged from the inoculation using a loop 19 abolished mutant that is not capable of systemic trafficking. Our observation indicates the flexibility of multiple structural arrangements interchangeably exerting similar function at a particular RNA locus. Taken together, this study deepens the understanding of RNA structural motifs regulated viroid RNA trafficking, which has broad implications for studying RNA intercellular trafficking as well. PMID- 29601478 TI - Did Harvey Learn from Katrina? Initial Observations of the Response to Companion Animals during Hurricane Harvey. AB - The aftermath of Hurricane Katrina in 2005 became the genesis of animal emergency management and created significant reforms in the US particularly the passage of the Pets Emergency and Transportation Standards Act in 2006 that required state and local emergency management arrangements to be pet- and service animal inclusive. More than a decade later Hurricane Harvey struck the Gulf states with all 68 directly related deaths occurring in the state of Texas. In this study, six key officials involved in the response underwent a semi-structured interview to investigate the impact of the PETS Act on preparedness and response. Though the results have limitations due to the low sample size, it was found that the PETS Act and the lessons of Hurricane Katrina had contributed to a positive cultural shift to including pets (companion animals) in emergency response. However, there was a general theme that plans required under the PETS Act were under-developed and many of the animal response lessons from previous emergencies remain unresolved. The study also observed the first empirical case of disaster hoarding which highlights the need for animal law enforcement agencies to be active in emergency response. PMID- 29601477 TI - Acupuncture as Add-On Treatment of the Positive, Negative, and Cognitive Symptoms of Patients with Schizophrenia: A Systematic Review. AB - Background: Schizophrenia is a severe psychiatric disorder that has a large impact on patients' lives. In addition to Western medicine, the use of additional treatments, such as acupuncture, in treating the positive, negative, and cognitive symptoms is increasing. Methods: We conducted a systematic review on the use of acupuncture as an add-on treatment for patients with schizophrenia that are in regular care, with a special focus on the treatment of the often accompanying sleep disorders. In this study, we searched the Medline, ScienceDirect, Cochrane Library, Scopus, and ERIC databases with a cut-off date of 31 December 2017, thereby following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) protocol. Results: Our search resulted in 26 eligible studies with 1181 patients with schizophrenia who received acupuncture treatment. Most studies showed limited evidence for the use of acupuncture as add-on therapy in the treatment of the positive, negative, and cognitive symptoms, but beneficial effects have been reported in the treatment of the accompanying sleep disorders. Conclusions: Limited evidence was found for the use of acupuncture as add-on therapy in the treatment of patients with schizophrenia; however, positive results were found in the treatment of sleep disorders, but this result needs to be confirmed in large, randomized, controlled trials. PMID- 29601479 TI - Burden and Risk Factors for Cold-Related Illness and Death in New York City. AB - Exposure to cold weather can cause cold-related illness and death, which are preventable. To understand the current burden, risk factors, and circumstances of exposure for illness and death directly attributed to cold, we examined hospital discharge, death certificate, and medical examiner data during the cold season from 2005 to 2014 in New York City (NYC), the largest city in the United States. On average each year, there were 180 treat-and-release emergency department visits (average annual rate of 21.6 per million) and 240 hospital admissions (29.6 per million) for cold-related illness, and 15 cold-related deaths (1.8 per million). Seventy-five percent of decedents were exposed outdoors. About half of those exposed outdoors were homeless or suspected to be homeless. Of the 25% of decedents exposed indoors, none had home heat and nearly all were living in single-family or row homes. The majority of deaths and illnesses occurred outside of periods of extreme cold. Unsheltered homeless individuals, people who use substances and become incapacitated outdoors, and older adults with medical and psychiatric conditions without home heat are most at risk. This information can inform public health prevention strategies and interventions. PMID- 29601480 TI - On-Demand Bioadhesive Dendrimers with Reduced Cytotoxicity. AB - Tissue adhesives based on polyamidoamine (PAMAM) dendrimer, grafted with UV sensitive aryldiazirine (PAMAM-g-diazirine) are promising new candidates for light active adhesion on soft tissues. Diazirine carbene precursors form interfacial and intermolecular covalent crosslinks with tissues after UV light activation that requires no premixing or inclusion of free radical initiators. However, primary amines on the PAMAM dendrimer surface present a potential risk due to their cytotoxic and immunological effects. PAMAM-g-diazirine formulations with cationic pendant amines converted into neutral amide groups were evaluated. In vitro toxicity is reduced by an order of magnitude upon amine capping while retaining bioadhesive properties. The in vivo immunological response to PAMAM-g diazirine formulations was found to be optimal in comparison to standard poly(lactic-co-glycolic acid) (PLGA) thin films. PMID- 29601481 TI - A Co-Precursor Approach Coupled with a Supercritical Modification Method for Constructing Highly Transparent and Superhydrophobic Polymethylsilsesquioxane Aerogels. AB - Polymethylsilsesquioxane (PMSQ) aerogels obtained from methyltrimethoxysilane (MTMS) are well-known high-performance porous materials. Highly transparent and hydrophobic PMSQ aerogel would play an important role in transparent vacuum insulation panels. Herein, the co-precursor approach and supercritical modification method were developed to prepare the PMSQ aerogels with high transparency and superhydrophobicity. Firstly, benefiting from the introduction of tetramethoxysilane (TMOS) in the precursor, the pore structure became more uniform and the particle size was decreased. As the TMOS content increased, the light transmittance increased gradually from 54.0% to 81.2%, whereas the contact angle of water droplet decreased from 141 degrees to 99.9 degrees , ascribed to the increase of hydroxyl groups on the skeleton surface. Hence, the supercritical modification method utilizing hexamethyldisilazane was also introduced to enhance the hydrophobic methyl groups on the aerogel's surface. As a result, the obtained aerogels revealed superhydrophobicity with a contact angle of 155 degrees . Meanwhile, the developed surface modification method did not lead to any significant changes in the pore structure resulting in the superhydrophobic aerogel with a high transparency of 77.2%. The proposed co-precursor approach and supercritical modification method provide a new horizon in the fabrication of highly transparent and superhydrophobic PMSQ aerogels. PMID- 29601482 TI - Oxamate, but Not Selective Targeting of LDH-A, Inhibits Medulloblastoma Cell Glycolysis, Growth and Motility. AB - Medulloblastoma is the most common malignant paediatric brain tumour and current therapies often leave patients with severe neurological disabilities. Four major molecular groups of medulloblastoma have been identified (Wnt, Shh, Group 3 and Group 4), which include additional, recently defined subgroups with different prognosis and genetic characteristics. Lactate dehydrogenase A (LDHA) is a key enzyme in the aerobic glycolysis pathway, an abnormal metabolic pathway commonly observed in cancers, associated with tumour progression and metastasis. Studies indicate MBs have a glycolytic phenotype; however, LDHA has not yet been explored as a therapeutic target for medulloblastoma. LDHA expression was examined in medulloblastoma subgroups and cell lines. The effects of LDHA inhibition by oxamate or LDHA siRNA on medulloblastoma cell line metabolism, migration and proliferation were examined. LDHA was significantly overexpressed in Group 3 and Wnt MBs compared to non-neoplastic cerebellum. Furthermore, we found that oxamate significantly attenuated glycolysis, proliferation and motility in medulloblastoma cell lines, but LDHA siRNA did not. We established that aerobic glycolysis is a potential therapeutic target for medulloblastoma, but broader LDH inhibition (LDHA, B, and C) may be more appropriate than LDHA inhibition alone. PMID- 29601484 TI - Optical Biosensors Based on Photonic Crystals Supporting Bound States in the Continuum. AB - A novel optical label-free bio-sensing platform based on a new class of resonances supported in a photonic crystal metasurface is reported herein. Molecular binding is detected as a shift in the resonant wavelength of the bound states in the continuum of radiation modes. The new configuration is applied to the recognition of the interaction between protein p53 and its protein regulatory partner murine double minute 2 (MDM2). A detection limit of 66 nM for the protein p53 is found. The device provides an excellent interrogation stability and loss free operation, requires minimal optical interrogation equipment and can be easily optimized to work in a wide wavelength range. PMID- 29601483 TI - Invertebrate Iridoviruses: A Glance over the Last Decade. AB - Members of the family Iridoviridae (iridovirids) are large dsDNA viruses that infect both invertebrate and vertebrate ectotherms and whose symptoms range in severity from minor reductions in host fitness to systemic disease and large scale mortality. Several characteristics have been useful for classifying iridoviruses; however, novel strains are continuously being discovered and, in many cases, reliable classification has been challenging. Further impeding classification, invertebrate iridoviruses (IIVs) can occasionally infect vertebrates; thus, host range is often not a useful criterion for classification. In this review, we discuss the current classification of iridovirids, focusing on genomic and structural features that distinguish vertebrate and invertebrate iridovirids and viral factors linked to host interactions in IIV6 (Invertebrate iridescent virus 6). In addition, we show for the first time how complete genome sequences of viral isolates can be leveraged to improve classification of new iridovirid isolates and resolve ambiguous relations. Improved classification of the iridoviruses may facilitate the identification of genus-specific virulence factors linked with diverse host phenotypes and host interactions. PMID- 29601485 TI - Biopsychosocial Assessment of Pain with Thermal Imaging of Emotional Facial Expression in Breast Cancer Survivors. AB - Background: Recent research has evaluated psychological and biological characteristics associated with pain in survivors of breast cancer (BC). Few studies consider their relationship with inflammatory activity. Voluntary facial expressions modify the autonomic activity and this may be useful in the hospital environment for clinical biopsychosocial assessment of pain. Methods: This research compared a BC survivors group under integral treatment (Oncology, Psychology, Nutrition) with a control group to assess the intensity of pain, behavioral interference, anxiety, depression, temperament-expression, anger control, social isolation, emotional regulation, and alexithymia and inflammatory activity, with salivary interleukin 6 (IL-6). Then, a psychophysiological evaluation through repeated measures of facial infrared thermal imaging (IRT) and hands in baseline-positive facial expression (joy)-negative facial expression (pain)-relaxation (diaphragmatic breathing). Results: The results showed changes in the IRT (p < 0.05) during the execution of facial expressions in the chin, perinasal, periorbital, frontal, nose, and fingers areas in both groups. No differences were found in the IL-6 level among the aforementioned groups, but an association with baseline nasal temperature (p < 0.001) was observable. The BC group had higher alexithymia score (p < 0.01) but lower social isolation (p < 0.05), in comparison to the control group. Conclusions: In the low- and medium concentration groups of IL-6, the psychophysiological intervention proposed in this study has a greater effect than on the high concentration group of IL-6. This will be considered in the design of psychological and psychosocial interventions for the treatment of pain. PMID- 29601486 TI - In Situ-Based Gels for Nose to Brain Delivery for the Treatment of Neurological Diseases. AB - In situ-based gel drug delivery systems that can bypass the blood-brain barrier, deliver the therapeutics to the desired site, reduce peripheral toxicity and control drug release kinetics have been developed. Some of the therapeutics used to treat neurological diseases suffer from poor bioavailability. Preclinical reports from several researchers have proven that the delivery of drugs to the brain via the nose-to-brain route using in situ gels holds great promise. However, safety issues on the toxicity of the nasal mucosa, transportation of the drugs to specific brain regions and determination of the required dose are factors that must be considered when designing these gels. This review will be focused on in situ-based gels that are used for the delivery of therapeutics via the nose-to-brain route, preclinical reports and challenges. PMID- 29601487 TI - Gene-Therapeutic Strategies Targeting Angiogenesis in Peripheral Artery Disease. AB - The World Health Organization announced that cardiovascular disease is the number one cause of death globally, representing 31% of all global deaths. Coronary artery disease (CAD) affects approximately 5% of the US population aged 40 years and older. With an age-adjusted prevalence of approximately 12%, peripheral artery disease (PAD) affects at least 8 to 12 million Americans. Both CAD and PAD are caused by mainly atherosclerosis, the hardening and narrowing of arteries over the years by lipid deposition in the vascular bed. Despite the significant advances in interventions for revascularization and intensive medical care, patients with CAD or PAD who undergo percutaneous transluminal angioplasty have a persistent high rate of myocardial infarction, amputation, and death. Therefore, new therapeutic strategies are urgently needed for these patients. To overcome this unmet need, therapeutic angiogenesis using angiogenic growth factors has evolved in an attempt to stimulate the growth of new vasculature to compensate for tissue ischemia. After nearly 20 years of investigation, there is growing evidence of successful or unsuccessful gene therapy for ischemic heart and limb disease. This review will discuss basic and clinical data of therapeutic angiogenesis studies employing angiogenic growth factors for PAD patients and will draw conclusions on the basis of our current understanding of the biological processes of new vascularization. PMID- 29601488 TI - A Comparison of the Satiety Effects of a Fruit Smoothie, Its Fresh Fruit Equivalent and Other Drinks. AB - Energy-containing liquids are claimed to have relatively low satiating power, although energy in liquids is not without effect on appetite. Using the preload test-meal method, effects on fullness and energy intake compensation were compared across four drinks (water, blackcurrant squash, milk and fruit smoothie) and the fresh fruit equivalent of the smoothie. Preload volumes were similar, and the energy value of each preload was 569 kJ, except for water (0 kJ). Healthy, adult participants rated the preloads for liking, enjoyment, satisfaction, familiarity and how 'food-like' they seemed. The preload to test-meal interval was 2 min (n = 23) or 2 h (n = 24). The effects of the preloads on fullness varied with food-likeness and the rate at which they were consumed. In contrast, energy intake compensation versus water did not differ between the energy containing preloads, although it decreased over time (from 82% at 2 min to 12% at 2 h). In conclusion, although fullness increased with food-likeness, subsequent energy intake compensation did not differ for energy/nutrients consumed in drinks compared with a food. The results also support the proposal that food intake is influenced predominantly by the immediate, but rapidly waning, post-ingestive effects of the previous 'meal' (rather than by changes in energy balance). PMID- 29601489 TI - The Relationship between Sleep Time and Mental Health Problems According to the Strengths and Difficulties Questionnaire in Children after an Earthquake Disaster: The Fukushima Health Management Survey. AB - A cross-sectional study was performed on the adverse effects of sleep time on the mental health of children after the Great East Japan Earthquake and subsequent nuclear reactor accident in March 2011. The target participants were children aged 4-15 years living inside the government-designated evacuation zone as of 11 March 2011 (n = 29,585). The participants' parents/guardians completed the Strengths and Difficulties Questionnaire (SDQ) and sleep time data were obtained from the 2011 Fukushima Health Management Survey. A total of 18,745 valid responses were returned. We excluded questionnaires with incomplete answers leaving 13,272 responses for the final analysis. First, we divided the children into three age groups for analysis. Second, we divided each age group into four or five groups based on sleep time per day. We used SDQ scores >=16 to indicate a high risk of mental health problems. In the 4-6-year-old group, those with a sleep time of <9 h had a higher risk. In the 7-12-year-old group, those with >=10 h of sleep time had a higher risk. In the 13-15-year-old group, those with >=9 h of sleep time had a higher risk. Shorter sleep time was associated with a higher risk of mental health in 4-6-year-olds. On the other hand, oversleeping was associated with a high risk of mental health in 7-15-year-olds. PMID- 29601490 TI - Synthesis of Pt-Pd Bimetallic Porous Nanostructures as Electrocatalysts for the Methanol Oxidation Reaction. AB - Pt-based bimetallic nanostructures have attracted a great deal of attention due to their unique nanostructures and excellent catalytic properties. In this study, we prepared porous Pt-Pd nanoparticles using an efficient, one-pot co-reduction process without using any templates or toxic reactants. In this process, Pt-Pd nanoparticles with different nanostructures were obtained by adjusting the temperature and ratio of the two precursors; and their catalytic properties for the oxidation of methanol were studied. The porous Pt-Pd nanostructures showed better electrocatalytic activity for the oxidation of methanol with a higher current density (0.67 mA/cm2), compared with the commercial Pt/C catalyst (0.31 mA/cm2). This method provides one easy pathway to economically prepare different alloy nanostructures for various applications. PMID- 29601491 TI - Whole-Genome Comparison Reveals Heterogeneous Divergence and Mutation Hotspots in Chloroplast Genome of Eucommia ulmoides Oliver. AB - Eucommia ulmoides (E. ulmoides), the sole species of Eucommiaceae with high importance of medicinal and industrial values, is a Tertiary relic plant that is endemic to China. However, the population genetics study of E. ulmoides lags far behind largely due to the scarcity of genomic data. In this study, one complete chloroplast (cp) genome of E. ulmoides was generated via the genome skimming approach and compared to another available E. ulmoides cp genome comprehensively at the genome scale. We found that the structure of the cp genome in E. ulmoides was highly consistent with genome size variation which might result from DNA repeat variations in the two E. ulmoides cp genomes. Heterogeneous sequence divergence patterns were revealed in different regions of the E. ulmoides cp genomes, with most (59 out of 75) of the detected SNPs (single nucleotide polymorphisms) located in the gene regions, whereas most (50 out of 80) of the indels (insertions/deletions) were distributed in the intergenic spacers. In addition, we also found that all the 40 putative coding-region-located SNPs were synonymous mutations. A total of 71 polymorphic cpDNA fragments were further identified, among which 20 loci were selected as potential molecular markers for subsequent population genetics studies of E. ulmoides. Moreover, eight polymorphic cpSSR loci were also developed. The sister relationship between E. ulmoides and Aucuba japonica in Garryales was also confirmed based on the cp phylogenomic analyses. Overall, this study will shed new light on the conservation genomics of this endangered plant in the future. PMID- 29601493 TI - De-Prescribing of Psychotropic Medications in the Adult Population with Intellectual Disabilities: A Commentary. AB - The population with intellectual disabilities is one of the most vulnerable groups in society. Medication use is the main therapeutic intervention in this population and psychotropic medications can be prescribed for mental health conditions and for challenging behaviors. Clinical experience of prescribers and pharmacists working with people with intellectual disabilities suggests that reducing or stopping psychotropic medication is not always straightforward. What is required is rational, rather than rationed, prescribing of psychotropic medications. Concerns of clinicians working with people with intellectual disabilities and both formal and informal carers can result in maintenance of the 'status quo.' Setting-related, carer-related and staff-related factors play an important role in the real world of people with intellectual disabilities. Optimizing medication regimens in the adult population with intellectual disabilities is complicated but it is recognized that efforts to improve the current state of medication utilization are required for many individuals with intellectual disabilities. Pharmacists have a responsibility to include the person and/or their carer in their efforts to promote optimization of psychotropic medication use in environment in which the person lives. PMID- 29601494 TI - The Burden of Serious Fungal Infections in Cameroon. AB - Fungal infections are frequent in Cameroon, and invasive fungal infections are sometimes detected, usually in HIV-infected patients. For these reasons, we have estimated the burden of fungal infections. Using published literature and population estimates for the at-risk group, we used deterministic modelling to derive national incidence and prevalence estimates for the most serious fungal diseases. HIV infection is common and an estimated 120,000 have CD4 counts <200 * 106/mL and commonly present with opportunistic infection. Oesophageal candidiasis in HIV is common, and in poorly controlled diabetics. We estimate 6720 cases of cryptococcal meningitis, 9000 of Pneumocystis pneumonia, 1800 of disseminated histoplasmosis annually complicating AIDS, and 1200 deaths from invasive aspergillosis in AIDS, but there are no data. We found that 2.4% of adults have chronic obstructive pulmonary disease (COPD) and 2.65% have asthma, with "fungal asthma" affecting 20,000. Chronic pulmonary aspergillosis probably affects about 5000 people, predominantly after tuberculosis but also with COPD and other lung diseases. Also, tinea capitis in schoolchildren is frequent. Overall, an estimated 1,235,775 people are affected by a serious fungal infection. There is an urgent need for government and clinician attention, improved laboratory facilities, fungal diagnostic tests, and competent laboratory technicians, as well as all World Health Organization (WHO)-endorsed essential antifungal drugs to be made available, as only fluconazole is registered and available in the country. PMID- 29601495 TI - A Study of Calcium-Silicate-Hydrate/Polymer Nanocomposites Fabricated Using the Layer-By-Layer Method. AB - Calcium-silicate-hydrate (CSH)/polymer nanocomposites were synthesized with the layer-by-layer (LBL) method, and their morphology and mechanical properties were investigated using atomic force microscopy (AFM) imaging and AFM nanoindentation. Different sets of polymers were used to produce CSH/polymer nanocomposites. The effect of different factors including dipping time, calcium to silicate ratios (C/S ratios) and pH on morphology was investigated. CSH/polymer nanocomposites made with different sets of polymers showed variation in morphologies. However, the Young’s modulus did not seem to reveal significant differences between the nanocomposites studied here. In nanocomposites containing graphene oxide (GO) nanosheet, an increase in the density of CSH particles was observed on the GO nanosheet compared to areas away from the GO nanosheet, providing evidence for improved nucleation of CSH in the presence of GO nanosheets. An increase in roughness and a reduction in the packing density in nanocomposites containing GO nanosheets was observed. PMID- 29601492 TI - Obesity, Inflammation, Toll-Like Receptor 4 and Fatty Acids. AB - Obesity leads to an inflammatory condition that is directly involved in the etiology of cardiovascular diseases, type 2 diabetes mellitus, and certain types of cancer. The classic inflammatory response is an acute reaction to infections or to tissue injuries, and it tends to move towards resolution and homeostasis. However, the inflammatory process that was observed in individuals affected by obesity and metabolic syndrome differs from the classical inflammatory response in certain respects. This inflammatory process manifests itself systemically and it is characterized by a chronic low-intensity reaction. The toll-like receptor 4 (TLR4) signaling pathway is acknowledged as one of the main triggers of the obesity-induced inflammatory response. The aim of the present review is to describe the role that is played by the TLR4 signaling pathway in the inflammatory response and its modulation by saturated and omega-3 polyunsaturated fatty acids. Studies indicate that saturated fatty acids can induce inflammation by activating the TLR4 signaling pathway. Conversely, omega-3 polyunsaturated fatty acids, such as eicosapentaenoic acid and docosahexaenoic acid, exert anti inflammatory actions through the attenuation of the activation of the TLR4 signaling pathway by either lipopolysaccharides or saturated fatty acids. PMID- 29601496 TI - PMMA-g-OEtOx Graft Copolymers: Influence of Grafting Degree and Side Chain Length on the Conformation in Aqueous Solution. AB - Depending on the degree of grafting (DG) and the side chain degree of polymerization (DP), graft copolymers may feature properties similar to statistical copolymers or to block copolymers. This issue is approached by studying aqueous solutions of PMMA-g-OEtOx graft copolymers comprising a hydrophobic poly(methyl methacrylate) (PMMA) backbone and hydrophilic oligo(2 ethyl-2-oxazoline) (OEtOx) side chains. The graft copolymers were synthesized via reversible addition-fragmentation chain transfer (RAFT) copolymerization of methyl methacrylate (MMA) and OEtOx-methacrylate macromonomers of varying DP. All aqueous solutions of PMMA-g-OEtOx (9% ≤ DG ≤ 34%; 5 ≤ side chain DP ≤ 24) revealed lower critical solution temperature behavior. The graft copolymer architecture significantly influenced the aggregation behavior, the conformation in aqueous solution and the coil to globule transition, as verified by means of turbidimetry, dynamic light scattering, nuclear magnetic resonance spectroscopy, and analytical ultracentrifugation. The aggregation behavior of graft copolymers with a side chain DP of 5 was significantly affected by small variations of the DG, occasionally forming mesoglobules above the cloud point temperature (Tcp), which was around human body temperature. On the other hand, PMMA-g-OEtOx with elongated side chains assembled into well-defined structures below the Tcp (apparent aggregation number (Nagg = 10)) that were able to solubilize Disperse Orange 3. The thermoresponsive behavior of aqueous solutions thus resembled that of micelles comprising a poly(2-ethyl-2-oxazoline) (PEtOx) shell (Tcp > 60 °C). PMID- 29601497 TI - Efforts to Improve the Seasonal Influenza Vaccine. AB - Influenza viruses infect approximately 20% of the global population annually, resulting in hundreds of thousands of deaths. While there are Food and Drug Administration (FDA) approved antiviral drugs for combating the disease, vaccination remains the best strategy for preventing infection. Due to the rapid mutation rate of influenza viruses, vaccine formulations need to be updated every year to provide adequate protection. In recent years, a great amount of effort has been focused on the development of a universal vaccine capable of eliciting broadly protective immunity. While universal influenza vaccines clearly have the best potential to provide long-lasting protection against influenza viruses, the timeline for their development, as well as the true universality of protection they afford, remains uncertain. In an attempt to reduce influenza disease burden while universal vaccines are developed and tested, many groups are working on a variety of strategies to improve the efficacy of the standard seasonal vaccine. This review will highlight the different techniques and technologies that have been, or are being, developed to improve the seasonal vaccination efforts against influenza viruses. PMID- 29601498 TI - Steroidal Constituents from Roots and Rhizomes of Smilacina japonica. AB - Four new steroidal constituents (1-4) along with two known steroidal glycosides (5 and 6) were isolated from the roots and rhizomes of Smilacina japonica. Analysis of their physicochemical properties and spectroscopic profiles identified the compounds as (25S)-5alpha-spirostan-9(11)-en-3beta, 17alpha-diol (1); (25S)-5alpha-spirostan-9(11)-en-3beta, 12beta-diol (2); (25S)-5alpha spirostan-9(11)-en-3beta, 17alpha-diol-3-O-beta-d-glucopyranoside (3); (25S) 5alpha-spirostan-9(11)-en-3beta, 17alpha-diol-3-O-beta-d-glucopyranosyl-(1->2) [beta-d-glucopyranosyl-(1->3)]-beta-d-galactopyranoside (4); japonicoside B (5); and japonicoside C (6). All six compounds showed cytotoxic activity against SMMC 7712, Bel-7402, A549, H460, and K562 human cancer cells. PMID- 29601499 TI - Short-Term Degradation of Bi-Component Electrospun Fibers: Qualitative and Quantitative Evaluations via AFM Analysis. AB - Electrospun polymeric fibers are currently used as 3D models for in vitro applications in biomedical areas, i.e., tissue engineering, cell and drug delivery. The high customization of the electrospinning process offers numerous opportunities to manipulate and control surface area, fiber diameter, and fiber density to evaluate the response of cells under different morphological and/or biochemical stimuli. The aim of this study was to investigate-via atomic force microscopy (AFM)-the chemical and morphological changes in bi-component electrospun fibers (BEFs) during the in vitro degradation process using a biological medium. BEFs were fabricated by electrospinning a mixture of synthetic polycaprolactone (PCL)-and natural polymers (gelatin) into a binary solution. During the hydrolytic degradation of protein, no significant remarkable effects were recognized in terms of fiber integrity. However, increases in surface roughness as well as a decrease in fiber diameter as a function of the degradation conditions were detected. We suggest that morphological and chemical changes due to the local release of gelatin positively influence cell behavior in culture, in terms of cell adhesion and spreading, thus working to mimic the native microenvironment of natural tissues. PMID- 29601500 TI - Novel Anisotropic Ductility of a High Strength Annealed Ti-20Zr-6.5Al-4V Alloy. AB - In this work, we investigate the mechanical properties of an annealed high strength Ti-20Zr-6.5Al-4V alloy in uniaxial tensile tests in different directions. The results show that the alloy exhibits obvious anisotropic ductility in different directions, while the tensile strength of the alloy remains almost unchanged. This phenomenon is closely related to alpha laths with similar orientations along the prior-beta grain boundaries. These alpha laths significantly affect the initiation and propagation of cracks when the alloy reaches its yield limit, thereby affecting the ductility of the alloy, such that it exhibits anisotropic ductility. PMID- 29601501 TI - Simultaneous Determination of Procainamide and N-acetylprocainamide in Rat Plasma by Ultra-High-Pressure Liquid Chromatography Coupled with a Diode Array Detector and Its Application to a Pharmacokinetic Study in Rats. AB - A simple, sensitive, and reliable reversed-phase, Ultra-High-Pressure Liquid Chromatography (UHPLC) coupled with a Diode Array Detector (DAD) method for the simultaneous determination of Procainamide (PA) and its major metabolite, N acetylprocainamide (NAPA), in rat plasma was developed and validated. A simple deproteinization method with methanol was applied to the rat plasma samples, which were analyzed using UHPLC equipped with DAD at 280 nm, and a SynergiTM 4 um polar, reversed-phase column using 1% acetic acid (pH 5.5) and methanol (76:24, v/v) as eluent in isocratic mode at a flow rate 0.2 mL/min. The method showed good linearity (r2 > 0.998) over the concentration range of 20-100,000 and 20 10,000 ng/mL for PA and NAPA, respectively. Intra- and inter-day accuracies ranged from 97.7 to 110.9%, and precision was <10.5% for PA and 99.7 to 109.2 and <10.5%, respectively, for NAPA. The lower limit of quantification was 20 ng/mL for both compounds. This is the first report of the UHPLC-DAD bioanalytical method for simultaneous measurement of PA and NAPA. The most obvious advantage of this method over previously reported HPLC methods is that it requires small sample and injection volumes, with a straightforward, one-step sample preparation. It overcomes the limitations of previous methods, which use large sample volume and complex sample preparation. The devised method was successfully applied to the quantification of PA and NAPA after an intravenous bolus administration of 10 mg/kg procainamide hydrochloride to rats. PMID- 29601502 TI - Demographics and Psychological Factors Associated with Adiposity in Nurses. AB - Adiposity-based chronic disease (ABCD), overweight-Ow- or obesity-Ob-) in health personnel is as frequent as in the general population, even though they understand well the importance of maintaining a healthy weight. Thus, it is highly likely that certain demographic and psychological conditions, independently of knowledge, are contributing to develop ABCD. The aim of this study was to examine the association between these factors and ABCD in nurses. Data were collected from a cross-sectional study conducted in a tertiary level institute in Mexico City from 2012 to 2013. All the nurses of the institute of any age, shift, service area and seniority were invited to participate and 55% (265) accepted. We found that ABCD was present in 79.6%, and low self-esteem and emotional distress in 26% and 10%, respectively. Working in the night shift (p = 0.031), labor seniority ≥15 years (p = 0.006), having 1 or more children (p = 0.021) and sessions of physical activity <30 min (p = 0.03) were associated with ABCD. Low self-esteem (OR = 2, 95% CI 1.150–3.07, p = 0.023) and emotional distress (OR = 4, 95% CI 1.472–13.078, p = 0.012) were associated with unhealthy lifestyle (less of 3 days per week and/or less of 30 min per session of physical activity and poor dietary habits). Therefore, strategies to prevent and treat ABCD must consider each context among nurses and psychological disorders need be identified to avoid an unhealthy lifestyle. PMID- 29601504 TI - Label-Free Electrochemical Immunoassay for C-Reactive Protein. AB - C-reactive protein (CRP) is one of the most expressed proteins in blood during acute phase inflammation, and its minute level increase has also been recognized for the clinical diagnosis of cardio vascular diseases. Unfortunately, the available commercial immunoassays are labour intensive, require large sample volumes, and have practical limitations, such as low stability and high production costs. Hence, we have developed a simple, cost effective, and label free electrochemical immunoassay for the measurement of CRP in a drop of serum sample using an immunosensor strip made up of a screen printed carbon electrode (SPE) modified with anti-CRP functionalized gold nanoparticles (AuNPs). The measurement relies on the decrease of the oxidation current of the redox indicator Fe3+/Fe2+, resulting from the immunoreaction between CRP and anti-CRP. Under optimal conditions, the present immunoassay measures CRP in a linear range from 0.4-200 nM (0.047-23.6 ug mL-1), with a detection limit of 0.15 nM (17 ng mL 1, S/N = 3) and sensitivity of 90.7 nA nM-1, in addition to a good reproducibility and storage stability. The analytical applicability of the presented immunoassay is verified by CRP measurements in human blood serum samples. This work provides the basis for a low-priced, safe, and easy-to-use point-of-care immunosensor assay to measure CRP at clinically relevant concentrations. PMID- 29601503 TI - The Immunomodulatory Capacity of an Epstein-Barr Virus Abortive Lytic Cycle: Potential Contribution to Viral Tumorigenesis. AB - Epstein-Barr virus (EBV) is characterized by a bipartite life cycle in which latent and lytic stages are alternated. Latency is compatible with long-lasting persistency within the infected host, while lytic expression, preferentially found in oropharyngeal epithelial tissue, is thought to favor host-to-host viral dissemination. The clinical importance of EBV relates to its association with cancer, which we think is mainly a consequence of the latency/persistency mechanisms. However, studies in murine models of tumorigenesis/lymphomagenesis indicate that the lytic cycle also contributes to cancer formation. Indeed, EBV lytic expression is often observed in established cell lines and tumor biopsies. Within the lytic cycle EBV expresses a handful of immunomodulatory (BCRF1, BARF1, BNLF2A, BGLF5 & BILF1) and anti-apoptotic (BHRF1 & BALF1) proteins. In this review, we discuss the evidence supporting an abortive lytic cycle in which these lytic genes are expressed, and how the immunomodulatory mechanisms of EBV and related herpesviruses Kaposi Sarcoma herpesvirus (KSHV) and human cytomegalovirus (HCMV) result in paracrine signals that feed tumor cells. An abortive lytic cycle would reconcile the need of lytic expression for viral tumorigenesis without relaying in a complete cycle that would induce cell lysis to release the newly formed infective viral particles. PMID- 29601505 TI - A Community-Driven Approach to Generate Urban Policy Recommendations for Obesity Prevention. AB - There is an increasing research interest in targeting interventions at the neighborhood level to prevent obesity. Healthy urban environments require including residents' perspectives to help understanding how urban environments relate to residents' food choices and physical activity levels. We describe an innovative community-driven process aimed to develop environmental recommendations for obesity prevention. We conducted this study in a low-income area in Madrid (Spain), using a collaborative citizen science approach. First, 36 participants of two previous Photovoice projects translated their findings into policy recommendations, using an adapted logical framework approach. Second, the research team grouped these recommendations into strategies for obesity prevention, using the deductive analytical strategy of successive approximation. Third, through a nominal group session including participants, researchers, public health practitioners and local policy-makers, we discussed and prioritized the obesity prevention recommendations. Participants identified 12 policy recommendations related to their food choices and 18 related to their physical activity. The research team grouped these into 11 concrete recommendations for obesity prevention. The 'top-three' ranked recommendations were: (1) to adequate and increase the number of public open spaces; (2) to improve the access and cost of existing sports facilities and (3) to reduce the cost of gluten-free and diabetic products. PMID- 29601506 TI - The Function of Personality in Suicidal Ideation from the Perspective of the Interpersonal-Psychological Theory of Suicide. AB - The Interpersonal-Psychological Theory of Suicide (IPTS) has been increasingly studied over the last years, responding to the demand for a valid framework addressing suicidality. Yet, only a few studies have explored the function of personality in the IPTS and none with clinical patients. We aimed to contribute to fill this gap in investigating the relationship between personality as conceptualized by the Five-Factor Model, the IPTS constructs, and a dimensional measure of current suicidal ideation. We conducted correlation, multiple linear regression, and path analyses based on a trait-interpersonal framework in a sample of 201 individuals visiting the psychiatric emergency room of a general hospital with current suicidal ideation. Neuroticism (positively) and openness (negatively) predicted perceived burdensomeness, while neuroticism (positively) and extraversion (negatively) predicted thwarted belongingness. Higher conscientiousness and lower extraversion were both predictors of the acquired capability for suicide. However, none of the models involving path analyses with IPTS variables as mediators of the relationship between personality traits and suicidal ideation was adequately adjusted to the data. Thus, it appears that personality plays a significant albeit modest role in suicidality when considered from an IPTS perspective. As personality is frequently assessed in the clinical routine, health professionals should consider it as complementary to detect individuals at risk of or presenting suicidal ideation. PMID- 29601507 TI - Metal (Ag/Ti)-Containing Hydrogenated Amorphous Carbon Nanocomposite Films with Enhanced Nanoscratch Resistance: Hybrid PECVD/PVD System and Microstructural Characteristics. AB - This study aimed to develop hydrogenated amorphous carbon thin films with embedded metallic nanoparticles (a-C:H:Me) of controlled size and concentration. Towards this end, a novel hybrid deposition system is presented that uses a combination of Plasma Enhanced Chemical Vapor Deposition (PECVD) and Physical Vapor Deposition (PVD) technologies. The a-C:H matrix was deposited through the acceleration of carbon ions generated through a radio-frequency (RF) plasma source by cracking methane, whereas metallic nanoparticles were generated and deposited using terminated gas condensation (TGC) technology. The resulting material was a hydrogenated amorphous carbon film with controlled physical properties and evenly dispersed metallic nanoparticles (here Ag or Ti). The physical, chemical, morphological and mechanical characteristics of the films were investigated through X-ray reflectivity (XRR), Raman spectroscopy, Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) and nanoscratch testing. The resulting amorphous carbon metal nanocomposite films (a-C:H:Ag and a-C:H:Ti) exhibited enhanced nanoscratch resistance (up to +50%) and low values of friction coefficient (<0.05), properties desirable for protective coatings and/or solid lubricant applications. The ability to form nanocomposite structures with tunable coating performance by potentially controlling the carbon bonding, hydrogen content, and the type/size/percent of metallic nanoparticles opens new avenues for a broad range of applications in which mechanical, physical, biological and/or combinatorial properties are required. PMID- 29601508 TI - Deep Sequencing-Based Transcriptome Profiling Reveals Avian Interferon-Stimulated Genes and Provides Comprehensive Insight into Newcastle Disease Virus-Induced Host Responses. AB - Newcastle disease virus (NDV) is an avian paramyxovirus that causes significant economic losses to the poultry industry worldwide, with variations in NDV pathogenicity due to the differences in virulence between strains. However, there is limited knowledge regarding the avian innate immune response to NDV infection. In this study, transcriptional profiles were obtained from chick embryo fibroblasts (CEFs) that were infected with the highly virulent NDV Herts/33 strain or the nonvirulent LaSota strain using RNA-seq. This yielded 8433 transcripts that were associated with NDV infection. This list of candidate genes was then further examined using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. It showed a high enrichment in the areas of cellular components and metabolic processes, with the cellular components possibly being associated with NDV pathogenicity. Among these 8433 transcripts, 3616 transcripts associated with interferon-stimulated genes (ISGs) were obtained; these transcripts are involved in metabolic processes, including protein phosphorylation and protein modification. These results provide further insight into the identification of genes that are involved in NDV infection. The global survey of changes in gene expression performed herein provides new insights into the complicated molecular mechanisms underlying virus and host interactions and will enable the use of new strategies to protect chickens against this virus. PMID- 29601509 TI - Tactile Sliding Behavior of R2R Mass-Produced PLLA Nanosheet towards Biomedical Device in Skin Applications. AB - In this research, sliding friction was measured between the fingertip and nanosheet on a silicon substrate under two conditions: dry and wet. By using a force transducer, the tactile friction force and applied load were measured. According to the experimental results, the relationship of friction force and applied load exhibits a positive correlation under both dry and wet conditions. In addition, the nanosheets are able to reduce the friction force and coefficient of friction (COF) compared to the reference sample, especially under the wet condition. Under the assumption of a full contact condition, the estimated contact area increases with larger applied loads. Furthermore, based on the wear observation, the skin sliding performance caused slight abrasions to the surface of the nanosheet samples with a mild wear track along the sliding direction. Overall, the sliding behavior between the skin and nanosheet was investigated in terms of friction force, COF, applied load, contact area, and wear. These findings can contribute to the nanosheet-related research towards biomedical devices in skin applications. PMID- 29601510 TI - Design and Implementation of a Dual-Mass MEMS Gyroscope with High Shock Resistance. AB - This paper presents the design and implementation of a dual-mass MEMS gyroscope with high shock resistance by improving the in-phase frequency of the gyroscope and by using a two-stage elastic stopper mechanism and proposes a Simulink shock model of the gyroscope equipped with the two-stage stopper mechanism, which is a very efficient method to evaluate the shock resistance of the gyroscope. The structural design takes into account both the mechanical sensitivity and the shock resistance. The design of the primary structure and the analysis of the stopper mechanism are first introduced. Based on the expression of the restoring force of the stopper beam, the analytical shock response model of the gyroscope is obtained. By this model, the shock response of the gyroscope is theoretically analyzed, and the appropriate structural parameters are obtained. Then, the correctness of the model is verified by finite element (FE) analysis, where the contact collision analysis is introduced in detail. The simulation results show that the application of the two-stage elastic stopper mechanism can effectively improve the shock resistance by more than 1900 g and 1500 g in the x- and y directions, respectively. Finally, experimental verifications are carried out by using a machete hammer on the micro-gyroscope prototype fabricated by the deep dry silicon on glass (DDSOG) technology. The results show that the shock resistance of the prototype along the x-, y- and z-axes all exceed 10,000 g. Moreover, the output of the gyroscope can return to normal in about 2 s. PMID- 29601511 TI - The Height-Adaptive Parameterized Step Length Measurement Method and Experiment Based on Motion Parameters. AB - In order to tackle the inaccurate step length measurement of people with different heights and in different motion states, a height-adaptive method of step length measurement based on motion parameters is proposed in this paper. This method takes people's height, stride frequency, and changing accelerometer output while walking into integrated consideration, and builds a dynamic and parameterized model of their step length. In this study, these parameters were calibrated with thirty sets of experiment data from people with different heights and in different motion states, which were then verified experimentally by motion data of randomly selected subjects, regardless of speed and height. The experiment results indicate that the height-adaptive step length measurement was realized, thus eliminating the influence of height exerted on step length measurement. PMID- 29601512 TI - Sensor-Based Optimized Control of the Full Load Instability in Large Hydraulic Turbines. AB - Hydropower plants are of paramount importance for the integration of intermittent renewable energy sources in the power grid. In order to match the energy generated and consumed, Large hydraulic turbines have to work under off-design conditions, which may lead to dangerous unstable operating points involving the hydraulic, mechanical and electrical system. Under these conditions, the stability of the grid and the safety of the power plant itself can be compromised. For many Francis Turbines one of these critical points, that usually limits the maximum output power, is the full load instability. Therefore, these machines usually work far away from this unstable point, reducing the effective operating range of the unit. In order to extend the operating range of the machine, working closer to this point with a reasonable safety margin, it is of paramount importance to monitor and to control relevant parameters of the unit, which have to be obtained with an accurate sensor acquisition strategy. Within the framework of a large EU project, field tests in a large Francis Turbine located in Canada (rated power of 444 MW) have been performed. Many different sensors were used to monitor several working parameters of the unit for all its operating range. Particularly for these tests, more than 80 signals, including ten type of different sensors and several operating signals that define the operating point of the unit, were simultaneously acquired. The present study, focuses on the optimization of the acquisition strategy, which includes type, number, location, acquisition frequency of the sensors and corresponding signal analysis to detect the full load instability and to prevent the unit from reaching this point. A systematic approach to determine this strategy has been followed. It has been found that some indicators obtained with different types of sensors are linearly correlated with the oscillating power. The optimized strategy has been determined based on the correlation characteristics (linearity, sensitivity and reactivity), the simplicity of the installation and the acquisition frequency necessary. Finally, an economic and easy implementable protection system based on the resulting optimized acquisition strategy is proposed. This system, which can be used in a generic Francis turbine with a similar full load instability, permits one to extend the operating range of the unit by working close to the instability with a reasonable safety margin. PMID- 29601513 TI - Exogenous Melatonin Confers Cadmium Tolerance by Counterbalancing the Hydrogen Peroxide Homeostasis in Wheat Seedlings. AB - Melatonin has emerged as a research highlight regarding its important role in regulating plant growth and the adaptation to the environmental stresses. In this study, we investigated how melatonin prevented the cadmium toxicity to wheat seedlings. The results demonstrated that cadmium induced the expression of melatonin biosynthesis-related genes and cause a significant increase of endogenous melatonin level. Melatonin treatment drastically alleviated the cadmium toxicity, resulting in increased plant height, biomass accumulation, and root growth. Cadmium and senescence treatment significantly increased the endogenous level of hydrogen peroxide, which was strictly counterbalanced by melatonin. Furthermore, melatonin treatment caused a significant increase of GSH (reduced glutathione) content and the GSH/GSSG (oxidized glutathione) ratio. The activities of two key antioxidant enzymes, ascorbate peroxidase (APX) and superoxide dismutase (SOD), but not catalase (CAT) and peroxidase (POD), were specifically improved by melatonin. Additionally, melatonin not only promoted the primary root growth, but also drastically enhanced the capacity of the seedling roots to degrade the exogenous hydrogen peroxide. These results suggested that melatonin played a key role in maintaining the hydrogen peroxide homeostasis, via regulation of the antioxidant systems. Conclusively, this study revealed a crucial protective role of melatonin in the regulation of cadmium resistance in wheat. PMID- 29601515 TI - Ridge Minimization of Ablated Morphologies on ITO Thin Films Using Squared Quasi Flat Top Beam. AB - In this study, we explore the improvements in pattern quality that was obtained with a femtosecond laser with quasi-flat top beam profiles at the ablated edge of indium tin oxide (ITO) thin films for the patterning of optoelectronic devices. To ablate the ITO thin films, a femtosecond laser is used that has a wavelength and pulse duration of 1030 nm and 190 fs, respectively. The squared quasi-flat top beam is obtained from a circular Gaussian beam using slits with varying x-y axes. Then, the patterned ITO thin films are measured using both scanning electron and atomic force microscopes. In the case of the Gaussian beam, the ridge height and width are approximately 39 nm and 1.1 MUm, respectively, whereas, when the quasi-flat top beam is used, the ridge height and width are approximately 7 nm and 0.25 MUm, respectively. PMID- 29601514 TI - Diphenylphenoxy-Thiophene-PDI Dimers as Acceptors for OPV Applications with Open Circuit Voltage Approaching 1 Volt. AB - Two new perylenediimides (PDIs) have been developed for use as electron acceptors in solution-processed bulk heterojunction solar cells. The compounds were designed to exhibit maximal solubility in organic solvents, and reduced aggregation in the solid state. In order to achieve this, diphenylphenoxy groups were used to functionalize a monomeric PDI core, and two PDI dimers were bridged with either one or two thiophene units. In photovoltaic devices prepared using PDI dimers and a monomer in conjunction with PTB7, it was found that the formation of crystalline domains in either the acceptor or donor was completely suppressed. Atomic force microscopy, X-ray diffraction, charge carrier mobility measurements and recombination kinetics studies all suggest that the lack of crystallinity in the active layer induces a significant drop in electron mobility. Significant surface recombination losses associated with a lack of segregation in the material were also identified as a significant loss mechanism. Finally, the monomeric PDI was found to have sub-optimum LUMO energy matching the cathode contact, thus limiting charge carrier extraction. Despite these setbacks, all PDIs produced high open circuit voltages, reaching almost 1 V in one particular case. PMID- 29601516 TI - Identification of Requirements for Computer-Supported Matching of Food Consumption Data with Food Composition Data. AB - This paper identifies the requirements for computer-supported food matching, in order to address not only national and European but also international current related needs and represents an integrated research contribution of the FP7 EuroDISH project. The available classification and coding systems and the specific problems of food matching are summarized and a new concept for food matching based on optimization methods and machine-based learning is proposed. To illustrate and test this concept, a study has been conducted in four European countries (i.e., Germany, The Netherlands, Italy and the UK) using different classification and coding systems. This real case study enabled us to evaluate the new food matching concept and provide further recommendations for future work. In the first stage of the study, we prepared subsets of food consumption data described and classified using different systems, that had already been manually matched with national food composition data. Once the food matching algorithm was trained using this data, testing was performed on another subset of food consumption data. Experts from different countries validated food matching between consumption and composition data by selecting best matches from the options given by the matching algorithm without seeing the result of the previously made manual match. The evaluation of study results stressed the importance of the role and quality of the food composition database as compared to the selected classification and/or coding systems and the need to continue compiling national food composition data as eating habits and national dishes still vary between countries. Although some countries managed to collect extensive sets of food consumption data, these cannot be easily matched with food composition data if either food consumption or food composition data are not properly classified and described using any classification and coding systems. The study also showed that the level of human expertise played an important role, at least in the training stage. Both sets of data require continuous development to improve their quality in dietary assessment. PMID- 29601517 TI - The Mechanical Properties and In Vitro Biocompatibility of PM-Fabricated Ti-28Nb 35.4Zr Alloy for Orthopedic Implant Applications. AB - A biocompatible Ti-28Nb-35.4Zr alloy used as bone implant was fabricated through the powder metallurgy process. The effects of mechanical milling and sintering temperatures on the microstructure and mechanical properties were investigated systematically, before in vitro biocompatibility of full dense Ti-28Nb-35.4Zr alloy was evaluated by cytotoxicity tests. The results show that the mechanical milling and sintering temperatures have significantly effects on the density and mechanical properties of the alloys. The relative density of the alloy fabricated by the atomized powders at 1500 degrees C is only 83 +/- 1.8%, while the relative density of the alloy fabricated by the ball-milled powders can rapidly reach at 96.4 +/- 1.3% at 1500 degrees C. When the temperature was increased to 1550 degrees C, the alloy fabricated by ball-milled powders achieve full density (relative density is 98.1 +/- 1.2%). The PM-fabricated Ti-28Nb-35.4Zr alloy by ball-milled powders at 1550 degrees C can achieve a wide range of mechanical properties, with a compressive yield strength of 1058 +/- 35.1 MPa, elastic modulus of 50.8 +/- 3.9 GPa, and hardness of 65.8 +/- 1.5 HRA. The in vitro cytotoxicity test suggests that the PM-fabricated Ti-28Nb-35.4Zr alloy by ball milled powders at 1550 degrees C has no adverse effects on MC3T3-E1 cells with cytotoxicity ranking of 0 grade, which is nearly close to ELI Ti-6Al-4V or CP Ti. These properties and the net-shape manufacturability makes PM-fabricated Ti-28Nb 35.4Zr alloy a low-cost, highly-biocompatible, Ti-based biomedical alloy.

AB - P-113, which was originally derived from the human saliva protein histatin 5, is a histidine-rich antimicrobial peptide with the sequence AKRHHGYKRKFH. P-113 is currently undergoing phase II clinical trial as a pharmaceutical agent to fight against fungal infections in HIV patients with oral candidiasis. Previously, we developed a new procedure for the high-yield expression and purification of hG31P, an analogue and antagonist of human CXCL8. Moreover, we have successfully removed lipopolysaccharide (LPS, endotoxin) associated with hG31P in the expression with Escherichia coli. In this paper, we have used hG31P as a novel fusion protein for the expression and purification of P-113. The purity of the expressed P-113 is more than 95% and the yield is 4 mg P-113 per liter of E. coli cell culture in Luria-Bertani (LB) medium. The antimicrobial activity of the purified P-113 was tested. Furthermore, we used circular dichroism (CD) and nuclear magnetic resonance (NMR) spectroscopy to study the structural properties of P-113. Our results indicate that using hG31P as a fusion protein to obtain large quantities of P-113 is feasible and is easy to scale up for commercial production. An effective way of producing enough P-113 for future clinical studies is evident in this study. PMID- 29601520 TI - Ageing Study of Palm Oil and Coconut Oil in the Presence of Insulation Paper for Transformers Application. AB - This paper presents a sealed ageing study of palm oil (PO) and coconut oil (CO) in the presence of insulation paper. The type of PO under study is refined, bleached, and deodorized palm oil (RBDPO) olein. Three different variations of RBDPO and one sample of CO are aged at temperatures of 90 degrees C, 110 degrees C, and 130 degrees C. The properties of RBDPO and CO as well as paper under ageing are then analysed through dielectric and physicochemical measurements. It is found that the effect of ageing is not significant on the alternating current (AC) breakdown voltages and relative permittivities of RBDPO and CO. There is a slight increment trend of the resistivity for CO, while for all of the RBDPO, the resistivity slightly decreases as the ageing progresses. Only CO shows an apparent reduction of the dielectric dissipation factor. Throughout the ageing time, the acidities of all of the RBDPO and CO remain at low level, while the moisture in oils decreases. The tensile index (TI) of the papers for all of the RBDPO and CO retain more than 50% of the TI. A significant increment of the paper ageing rates of all of the RBDPO and CO is observed at an ageing temperature of 130 degrees C.

AB - A research investigation of "ant nest" corrosion (ANC) on copper tube was conducted in terms of the variables of the corrosion potential and pH value in 103 ppm copper formate solution over 20 days. The paper presents the surface and cross-sectional observations and examines Cu2O and H2O as the stable chemical species produced. A Cannizzaro reaction as a disproportionation reaction from formic acid and a comproportionation reaction from the metallic copper tube and copper formate solution critically influenced the ANC mechanism. The paper also categorizes the ANC attack as a rapid reaction system from the electrochemical point of view by using a polarization resistance curve. PMID- 29601523 TI - Genome-Wide Analysis of DCL, AGO, and RDR Gene Families in Pepper (Capsicum Annuum L.). AB - RNA silencing is an evolutionarily conserved mechanism that regulates variety of cellular processes in plants. Argonaute protein (AGO), Dicer-like protein (DCL) and RNA-dependent RNA polymerase (RDR) are critical components of RNA silencing. These efficient and indispensable components of the RNAi pathway have not been identified and characterized in pepper. In this study, we identified 12 CaAGO, 4 CaDCL and 6 CaRDR genes in pepper and compared them with those of Arabidopsis, tobacco, potato and tomato. Detailed phylogenetic analyses revealed that each CaAGO, CaDCL and CaRDR protein family were classified into four clades. The tissue specific expression and respond to abiotic or biotic stress were studied. The real-time quantitative polymerase chain reaction (PCR) results demonstrated that CaAGO2, CaAGO10b, CaDCL2 and CaDCL4 were upregulated with cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco mosaic virus (TMV) infections, whereas they showed difference expression patterns in response to abiotic stress. In addition, we found that many of the candidate genes were induced by phytohormones and H2O2 treatment. Our results provide useful information for further elucidation of gene silencing pathways and RNAi-mediated host immunity in pepper. PMID- 29601524 TI - The Mental Health Status and Intellectual Ability of Unwed Mothers Dwelling in Korean Shelter Homes. AB - Although many unwed mothers have issues concerning mental health and intellectual ability, little research has focused on their mental and cognitive status. Due to the public stigma attached to unwed mothers in South Korea, they tend to conceal their status and are less likely to seek psychiatric and psychological help. In this context, this study aims to assess the current status of their mental health and intellectual characteristics. A total of 48 unwed mothers from two shelter homes in South Korea agreed to participate in the study. We compared the mental health status of these unwed mothers with that of the general female population. Unwed mothers were more likely than those of the general female population to have mood disorders, post traumatic stress disorder (PTSD), alcohol and nicotine use disorders, and attention-deficit hyperactivity disorder (ADHD). Among the 48 unwed mothers, 20 (41.7%) had an IQ of less than 70, and the mean IQ (78.31) was significantly lower than the normalized mean IQ of the general female population. This study confirmed that unwed mothers dwelling in Korean shelter homes are more likely than the general female population to have mental disorders. PMID- 29601521 TI - Rebelling against the (Insulin) Resistance: A Review of the Proposed Insulin Sensitizing Actions of Soybeans, Chickpeas, and Their Bioactive Compounds. AB - Insulin resistance is a major risk factor for diseases such as type 2 diabetes and metabolic syndrome. Current methods for management of insulin resistance include pharmacological therapies and lifestyle modifications. Several clinical studies have shown that leguminous plants such as soybeans and pulses (dried beans, dried peas, chickpeas, lentils) are able to reduce insulin resistance and related type 2 diabetes parameters. However, to date, no one has summarized the evidence supporting a mechanism of action for soybeans and pulses that explains their ability to lower insulin resistance. While it is commonly assumed that the biological activities of soybeans and pulses are due to their antioxidant activities, these bioactive compounds may operate independent of their antioxidant properties and, thus, their ability to potentially improve insulin sensitivity via alternative mechanisms needs to be acknowledged. Based on published studies using in vivo and in vitro models representing insulin resistant states, the proposed mechanisms of action for insulin-sensitizing actions of soybeans, chickpeas, and their bioactive compounds include increasing glucose transporter-4 levels, inhibiting adipogenesis by down-regulating peroxisome proliferator-activated receptor-gamma, reducing adiposity, positively affecting adipokines, and increasing short-chain fatty acid-producing bacteria in the gut. Therefore, this review will discuss the current evidence surrounding the proposed mechanisms of action for soybeans and certain pulses, and their bioactive compounds, to effectively reduce insulin resistance. PMID- 29601525 TI - Discrete Indoor Three-Dimensional Localization System Based on Neural Networks Using Visible Light Communication. AB - Indoor localization estimation has become an attractive research topic due to growing interest in location-aware services. Many research works have proposed solving this problem by using wireless communication systems based on radiofrequency. Nevertheless, those approaches usually deliver an accuracy of up to two metres, since they are hindered by multipath propagation. On the other hand, in the last few years, the increasing use of light-emitting diodes in illumination systems has provided the emergence of Visible Light Communication technologies, in which data communication is performed by transmitting through the visible band of the electromagnetic spectrum. This brings a brand new approach to high accuracy indoor positioning because this kind of network is not affected by electromagnetic interferences and the received optical power is more stable than radio signals. Our research focus on to propose a fingerprinting indoor positioning estimation system based on neural networks to predict the device position in a 3D environment. Neural networks are an effective classification and predictive method. The localization system is built using a dataset of received signal strength coming from a grid of different points. From the these values, the position in Cartesian coordinates ( x , y , z ) is estimated. The use of three neural networks is proposed in this work, where each network is responsible for estimating the position by each axis. Experimental results indicate that the proposed system leads to substantial improvements to accuracy over the widely-used traditional fingerprinting methods, yielding an accuracy above 99% and an average error distance of 0.4 mm.

AB - Worldwide epidemiological data indicates insufficient diagnosis of diabetes as an increasing public health problem. In the search for solutions to this disadvantageous situation, occupational medicine health services seem to open up a unique opportunity to recognize some abnormalities in the early stages, especially among the asymptomatic working-age population. 316 workers underwent obligatory prophylactic examinations. In patients with twice assayed FGL >= 126 mg/dL (7.0 mmol/L) an additional intervention was implemented, including further diagnostic processes and therapy in General Practice (GP), followed by examination by an occupational health specialist within 3 months. The diagnosis of previously unknown diabetes was established among 2.5% of examined workers. All patients referred to the GP due to detected glycaemia impairment visited their doctor and finished the diagnostic process, took up therapy constrained by the occupational health physician to show the effects of intervention within 3 months. Prophylactic medical check-ups allow improved compliance and medical surveillance over glycaemia impairment in patients with prediabetes states, unknown diabetes or uncontrolled clinical course of diabetes. Considering fasting glucose level during mandatory prophylactic examination helps effective prevention of diabetes and its complications and thus provides public health system benefits.

In this study, six separate UCP1 regions: region-1 and region-2 (two parts of the promoter), region-3 and region-4 (two parts of intron 1), region-5 (spanning part of intron 5 and part of exon 6), and region-6 (spanning part of exon 6 and part of the 3'-UTR) from a variety of sheep breeds, were analysed using polymerase chain reaction-single-stranded conformational polymorphism (PCR-SSCP) analyses. In total, 30 single nucleotide polymorphisms (SNPs) were detected. Of these, 14 were located in the promoter, eight were found in intron 1, six were found in intron 5, and one was found in the 3'-UTR. One substitution in exon 6 (c.910A/G) would putatively result in an amino acid change (p.Thr304Ala). Twenty-eight novel SNPs and nine new haplotypes spanning region-2 to region-5 were identified. Of these nine haplotypes, five were common (B2-A5, C2-A5, C2-C5, A2-A5, and A2-B5) and four were rare (C2-B5, A2-C5, B2-C5, and B2-B5) in the sheep investigated. Of the five common haplotypes found in 314 New Zealand Romney sheep for which growth and carcass trait data were available, the presence of A2-B5 was associated with decreased hot carcass weight (HCW) and loin lean-meat yield (p = 0.006, p = 0.032, respectively), and the presence of C2-C5 was associated with a decreased proportion of leg lean-meat yield (p = 0.047) in the carcasses. No associations were found with growth traits. These results confirm that ovine UCP1 is a variable gene and may have value as a genetic marker for sheep breeding. PMID- 29601529 TI - Assessing the Health-Care Risk: The Clinical-VaR, a Key Indicator for Sound Management. AB - Clinical risk includes any undesirable situation or operational factor that may have negative consequences for patient safety or capable of causing an adverse event (AE). The AE, intentional or unintentionally, may be related to the human factor, that is, medical errors (MEs). Therefore, the importance of the health care risk management is a current and relevant issue on the agenda of many public and private institutions. The objective of the management has been evolving from the identification of AE to the assessment of cost-effective and efficient measures that improve the quality control through monitoring. Consequently, the goal of this paper is to propose a Key Risk Indicator (KRI) that enhances the advancement of the health-care management system. Thus, the application of the Value at Risk (VaR) concept in combination to the Loss Distribution Approach (LDA) is proved to be a proactive tool, within the frame of balanced scorecard (BSC), in health organizations. For this purpose, the historical events recorded in the Algo-OpData(r) database (Algorithmics Inc., Toronto, ON, Canada, IBM, Armonk, NY, USA) have been used. The analysis highlights the importance of risk in the financials outcomes of the sector. The results of paper show the usefulness of the Clinical-VaR to identify and monitor the risk and sustainability of the implemented controls. PMID- 29601528 TI - Stem Cells Therapy for Spinal Cord Injury. AB - Spinal cord injury (SCI), a serious public health issue, most likely occurs in previously healthy young adults. Current therapeutic strategies for SCI includes surgical decompression and pharmacotherapy, however, there is still no gold standard for the treatment of this devastating condition. Inefficiency and adverse effects of standard therapy indicate that novel therapeutic strategies are required. Because of their neuroregenerative and neuroprotective properties, stem cells are a promising tool for the treatment of SCI. Herein, we summarize and discuss the promising therapeutic potential of human embryonic stem cells (hESC), induced pluripotent stem cells (iPSC) and ependymal stem/progenitor cells (epSPC) for SCI. PMID- 29601530 TI - MetStabOn-Online Platform for Metabolic Stability Predictions. AB - Metabolic stability is an important parameter to be optimized during the complex process of designing new active compounds. Tuning this parameter with the simultaneous maintenance of a desired compound's activity is not an easy task due to the extreme complexity of metabolic pathways in living organisms. In this study, the platform for in silico qualitative evaluation of metabolic stability, expressed as half-lifetime and clearance was developed. The platform is based on the application of machine learning methods and separate models for human, rat and mouse data were constructed. The compounds' evaluation is qualitative and two types of experiments can be performed-regression, which is when the compound is assigned to one of the metabolic stability classes (low, medium, high) on the basis of numerical value of the predicted half-lifetime, and classification, in which the molecule is directly assessed as low, medium or high stability. The results show that the models have good predictive power, with accuracy values over 0.7 for all cases, for Sequential Minimal Optimization (SMO), k-nearest neighbor (IBk) and Random Forest algorithms. Additionally, for each of the analyzed compounds, 10 of the most similar structures from the training set (in terms of Tanimoto metric similarity) are identified and made available for download as separate files for more detailed manual inspection. The predictive power of the models was confronted with the external dataset, containing metabolic stability assessment via the GUSAR software, leading to good consistency of results for SMOreg and Naive Bayes (~0.8 on average). The tool is available online. PMID- 29601531 TI - A Hybrid Bionic Image Sensor Achieving FOV Extension and Foveated Imaging. AB - Based on bionic compound eye and human foveated imaging mechanisms, a hybrid bionic image sensor (HBIS) is proposed in this paper to extend the field of view (FOV) with high resolution. First, the hybrid bionic imaging model was developed and the structure parameters of the HBIS were deduced. Second, the properties of the HBIS were simulated, including FOV extension, super-resolution imaging, foveal ratio and so on. Third, a prototype of the HBIS was developed to validate the theory. Imaging experiments were carried out, and the results are in accordance with the simulations, proving the potential of the HBIS for large FOV and high-resolution imaging with low cost. PMID- 29601532 TI - Eight-Channel AC Magnetosusceptometer of Magnetic Nanoparticles for High Throughput and Ultra-High-Sensitivity Immunoassay. AB - An alternating-current magnetosusceptometer of antibody-functionalized magnetic nanoparticles (MNPs) was developed for immunomagnetic reduction (IMR). A high sensitivity, high-critical-temperature superconducting quantum interference device was used in the magnetosusceptometer. Minute levels of biomarkers of early stage neurodegeneration diseases were detectable in serum, but measuring each biomarker required approximately 4 h. Hence, an eight-channel platform was developed in this study to fit minimal screening requirements for Alzheimer's disease. Two consistent results were measured for three biomarkers, namely Abeta40, Abeta42, and tau protein, per human specimen. This paper presents the instrument configuration as well as critical characteristics, such as the low noise level variations among channels, a high signal-to-noise ratio, and the coefficient of variation for the biomarkers' IMR values. The instrument's ultrahigh sensitivity levels for the three biomarkers and the substantially shorter total measurement time in comparison with the previous single- and four channels platforms were also demonstrated in this study. Thus, the eight-channel instrument may serve as a powerful tool for clinical high-throughput screening of Alzheimer's disease. PMID- 29601533 TI - Aptamer-Modified Magnetic Beads in Biosensing. AB - Magnetic beads (MBs) are versatile tools for the purification, detection, and quantitative analysis of analytes from complex matrices. The superparamagnetic property of magnetic beads qualifies them for various analytical applications. To provide specificity, MBs can be decorated with ligands like aptamers, antibodies and peptides. In this context, aptamers are emerging as particular promising ligands due to a number of advantages. Most importantly, the chemical synthesis of aptamers enables straightforward and controlled chemical modification with linker molecules and dyes. Moreover, aptamers facilitate novel sensing strategies based on their oligonucleotide nature that cannot be realized with conventional peptide-based ligands. Due to these benefits, the combination of aptamers and MBs was already used in various analytical applications which are summarized in this article. PMID- 29601534 TI - Heterogeneity in Immune Cell Content in Malignant Pleural Mesothelioma. AB - Malignant pleural mesothelioma (MPM) is a highly aggressive cancer with limited therapy options and dismal prognosis. In recent years, the role of immune cells within the tumor microenvironment (TME) has become a major area of interest. In this review, we discuss the current knowledge of heterogeneity in immune cell content and checkpoint expression in MPM in relation to prognosis and prediction of treatment efficacy. Generally, immune-suppressive cells such as M2 macrophages, myeloid-derived suppressor cells and regulatory T cells are present within the TME, with extensive heterogeneity in cell numbers. Infiltration of effector cells such as cytotoxic T cells, natural killer cells and T helper cells is commonly found, also with substantial patient to patient heterogeneity. PD-L1 expression also varied greatly (16-65%). The infiltration of immune cells in tumor and associated stroma holds key prognostic and predictive implications. As such, there is a strong rationale for thoroughly mapping the TME to better target therapy in mesothelioma. Researchers should be aware of the extensive possibilities that exist for a tumor to evade the cytotoxic killing from the immune system. Therefore, no "one size fits all" treatment is likely to be found and focus should lie on the heterogeneity of the tumors and TME. PMID- 29601535 TI - Different Natural Selection Pressures on the atpF Gene in Evergreen Sclerophyllous and Deciduous Oak Species: Evidence from Comparative Analysis of the Complete Chloroplast Genome of Quercus aquifolioides with Other Oak Species. AB - Quercus is an economically important and phylogenetically complex genus in the family Fagaceae. Due to extensive hybridization and introgression, it is considered to be one of the most challenging plant taxa, both taxonomically and phylogenetically. Quercus aquifolioides is an evergreen sclerophyllous oak species that is endemic to, but widely distributed across, the Hengduanshan Biodiversity Hotspot in the Eastern Himalayas. Here, we compared the fully assembled chloroplast (cp) genome of Q. aquifolioides with those of three closely related species. The analysis revealed a cp genome ranging in size from 160,415 to 161,304 bp and with a typical quadripartite structure, composed of two inverted repeats (IRs) separated by a small single copy (SSC) and a large single copy (LSC) region. The genome organization, gene number, gene order, and GC content of these four Quercus cp genomes are similar to those of many angiosperm cp genomes. We also analyzed the Q. aquifolioides repeats and microsatellites. Investigating the effects of selection events on shared protein-coding genes using the Ka/Ks ratio showed that significant positive selection had acted on the atpF gene of Q. aquifolioides compared to two deciduous oak species, and that there had been significant purifying selection on the atpF gene in the chloroplast of evergreen sclerophyllous oak trees. In addition, site-specific selection analysis identified positively selected sites in 12 genes. Phylogenetic analysis based on shared protein-coding genes from 14 species defined Q. aquifolioides as belonging to sect. Heterobalanus and being closely related to Q. rubra and Q. aliena. Our findings provide valuable genetic information for use in accurately identifying species, resolving taxonomy, and reconstructing the phylogeny of the genus Quercus. PMID- 29601537 TI - Polar Cooperative Navigation Algorithm for Multi-Unmanned Underwater Vehicles Considering Communication Delays. AB - To solve the navigation accuracy problems of multi-Unmanned Underwater Vehicles (multi-UUVs) in the polar region, a polar cooperative navigation algorithm for multi-UUVs considering communication delays is proposed in this paper. UUVs are important pieces of equipment in ocean engineering for marine development. For UUVs to complete missions, precise navigation is necessary. It is difficult for UUVs to establish true headings because of the rapid convergence of Earth meridians and the severe polar environment. Based on the polar grid navigation algorithm, UUV navigation in the polar region can be accomplished with the Strapdown Inertial Navigation System (SINS) in the grid frame. To save costs, a leader-follower type of system is introduced in this paper. The leader UUV helps the follower UUVs to achieve high navigation accuracy. Follower UUVs correct their own states based on the information sent by the leader UUV and the relative position measured by ultra-short baseline (USBL) acoustic positioning. The underwater acoustic communication delay is quantized by the model. In this paper, considering underwater acoustic communication delay, the conventional adaptive Kalman filter (AKF) is modified to adapt to polar cooperative navigation. The results demonstrate that the polar cooperative navigation algorithm for multi UUVs that considers communication delays can effectively navigate the sailing of multi-UUVs in the polar region. PMID- 29601536 TI - In Vitro Characteristics of Phages to Guide 'Real Life' Phage Therapy Suitability. AB - The increasing problem of antibiotic-resistant pathogens has put enormous pressure on healthcare providers to reduce the application of antibiotics and to identify alternative therapies. Phages represent such an alternative with significant application potential, either on their own or in combination with antibiotics to enhance the effectiveness of traditional therapies. However, while phage therapy may offer exciting therapeutic opportunities, its evaluation for safe and appropriate use in humans needs to be guided initially by reliable and appropriate assessment techniques at the laboratory level. Here, we review the process of phage isolation and the application of individual pathogens or reference collections for the development of specific or "off-the-shelf" preparations. Furthermore, we evaluate current characterization approaches to assess the in vitro therapeutic potential of a phage including its spectrum of activity, genome characteristics, storage and administration requirements and effectiveness against biofilms. Lytic characteristics and the ability to overcome anti-phage systems are also covered. These attributes direct phage selection for their ultimate application as antimicrobial agents. We also discuss current pitfalls in this research area and propose that priority should be given to unify current phage characterization approaches. PMID- 29601538 TI - Brain-Computer Interface Spellers: A Review. AB - A Brain-Computer Interface (BCI) provides a novel non-muscular communication method via brain signals. A BCI-speller can be considered as one of the first published BCI applications and has opened the gate for many advances in the field. Although many BCI-spellers have been developed during the last few decades, to our knowledge, no reviews have described the different spellers proposed and studied in this vital field. The presented speller systems are categorized according to major BCI paradigms: P300, steady-state visual evoked potential (SSVEP), and motor imagery (MI). Different BCI paradigms require specific electroencephalogram (EEG) signal features and lead to the development of appropriate Graphical User Interfaces (GUIs). The purpose of this review is to consolidate the most successful BCI-spellers published since 2010, while mentioning some other older systems which were built explicitly for spelling purposes. We aim to assist researchers and concerned individuals in the field by illustrating the highlights of different spellers and presenting them in one review. It is almost impossible to carry out an objective comparison between different spellers, as each has its variables, parameters, and conditions. However, the gathered information and the provided taxonomy about different BCI spellers can be helpful, as it could identify suitable systems for first-hand users, as well as opportunities of development and learning from previous studies for BCI researchers. PMID- 29601540 TI - Cell Penetrating Capacity and Internalization Mechanisms Used by the Synthetic Peptide CIGB-552 and Its Relationship with Tumor Cell Line Sensitivity. AB - CIGB-552 is a twenty-amino-acid novel synthetic peptide that has proven to be effective in reducing tumor size and increasing lifespan in tumor-bearing mice. Such capability is conferred by its cell-penetrating peptide character, which allows it to enter cells and elicit a pro-apoptotic effect through its major mediator, COMMD1 protein. Cell-penetrating peptides are able to use different internalization mechanisms, such as endocytosis or direct transduction through the plasma membrane. Although CIGB-552 cytotoxicity has been evaluated in several non-tumor- and tumor-derived cell lines, no data regarding the relationship between cell line sensitivity, cell penetrating capacity, the internalization mechanisms involved, COMMD1 expression levels, or its subcellular localization has yet been produced. Here, we present the results obtained from a comparative analysis of CIGB-552 sensitivity, internalization capacity and the mechanisms involved in three human tumor-derived cell lines from different origins: mammary gland, colon and lung (MCF-7, HT-29 and H460, respectively). Furthermore, cell surface markers relevant for internalization processes such as phosphatidylserine, as well as CIGB-552 target COMMD1 expression/localization, were also evaluated. We found that both endocytosis and transduction are involved in CIGB-552 internalization in the three cell lines evaluated. However, CIGB-552 incorporation efficiency and contribution of each mechanism is cell-line dependent. Finally, sensitivity was directly correlated with high internalization capacity in those cell lines where endocytosis had a major contribution on CIGB 552 internalization. PMID- 29601539 TI - The Potential for Connexin Hemichannels to Drive Breast Cancer Progression through Regulation of the Inflammatory Response. AB - Over the past few decades, connexin hemichannels have become recognized as major players in modulating the inflammatory response. Chronic inflammation is documented to promote tumorigenesis and is a critical component of tumor progression. Furthermore, inflammation is strongly linked to angiogenesis, immunotolerance, invasiveness, metastasis, and resistance in breast cancers. In this review, the literature on the role of connexin hemichannels in inflammation is summarized, and the potential role for hemichannel-mediated inflammation in driving breast cancer progression is discussed. Lastly, the potential for connexin-based therapeutics to modulate the inflammatory component of the tumor microenvironment as an avenue for the treatment of breast cancer is also discussed. PMID- 29601541 TI - Expression Stabilities of Ten Candidate Reference Genes for RT-qPCR in Zanthoxylum bungeanum Maxim. AB - Real-time reverse transcription quantitative PCR has become a common method for studying gene expression, however, the optimal selection of stable reference genes is a prerequisite for obtaining accurate quantification of transcript abundance. Suitable reference genes for RT-qPCR have not yet been identified for Chinese prickly ash (Zanthoxylum bungeanum Maxim.). Chinese prickly ash is the source of an important food seasoning in China. In recent years, Chinese prickly ash has also been developed as a medicinal plant. The expression stabilities of ten genes (18S, 28S, EF, UBA, UBQ, TIF, NTB, TUA, RPS, and TIF5A) were evaluated in roots, stems, leaves, flowers and fruits at five developmental stages and also under stress from cold, drought, and salt. To do this we used three different statistical algorithms: geNorm, NormFinder and BestKeeper. Among the genes investigated, UBA and UBQ were found to be most stable for the different cultivars and different tissues examined, UBQ and TIF for fruit developmental stage. Meanwhile, EF and TUA were most stable under cold treatment, EF and UBQ under drought treatment and NTB and RPS under salt treatment. UBA and UBQ for all samples evaluated were most stably expressed, but 18S, TUA and RPS were found to be generally unreliable as reference genes. Our results provide a basis for the future selection of reference genes for biological research with Chinese prickly ash, under a variety of conditions. PMID- 29601543 TI - The Design of 3D-Printed Lattice-Reinforced Thickness-Varying Shell Molds for Castings. AB - 3D printing technologies have been used gradually for the fabrication of sand molds and cores for castings, even though these molds and cores are dense structures. In this paper, a generation method for lattice-reinforced thickness varying shell molds is proposed and presented. The first step is the discretization of the STL (Stereo Lithography) model of a casting into finite difference meshes. After this, a shell is formed by surrounding the casting with varying thickness, which is roughly proportional to the surface temperature distribution of the casting that is acquired by virtually cooling it in the environment. A regular lattice is subsequently constructed to support the shell. The outside surface of the shell and lattice in the cubic mesh format is then converted to STL format to serve as the external surface of the new shell mold. The internal surface of the new mold is the casting's surface with the normals of all of the triangles in STL format reversed. Experimental verification was performed on an Al alloy wheel hub casting. Its lattice-reinforced thickness varying shell mold was generated by the proposed method and fabricated by the binder jetting 3D printing. The poured wheel hub casting was sound and of good surface smoothness. The cooling rate of the wheel hub casting was greatly increased due to the shell mold structure. This lattice-reinforced thickness varying shell mold generation method is of great significance for mold design for castings to achieve cooling control. PMID- 29601542 TI - Identification and Comparison of Constituents of Aurantii Fructus and Aurantii Fructus Immaturus by UFLC-DAD-Triple TOF-MS/MS. AB - Although Aurantii Fructus (AF) and Aurantii Fructus Immaturus (AFI) are both the fruits of the same rutaceae plant at different stages of growth, they exert similar yet distinct clinical effects. The chemical composition is crucial for quality control as well as therapeutic application. To address this concern, it is significant to evaluate the similarities and differences of the constituents in both AF and AFI. The extract of AF and AFI were comprehensively analyzed by ultra fast liquid chromatography-photodiode array detector-triple-time of flight tandem mass spectrometry (UFLC-DAD-Triple TOF-MS/MS). Among the 40 compounds detected, 19 metabolites were detected in both the AF and AFI; whereas 13 compounds were only detected in AF and five constituents were exclusively detected in AFI. In particular, even in AFI, three compounds were only identified in AFI (Citrus aurantium' L. and its cultivar). Among the 18 compounds confirmed by standard database, 13 compounds were reported in AF and AFI for the first time. Furthermore, the distinction was also revealed by the content of naringin, hesperidin, neohesperidin, and synephrine. The study directly contributed to the similarities and differences of AF and AFI. Herein, similarities and the differences in chemical profiles of AF and AFI could explain the current clinical applications.

AB - Directionally solidified Al2O3/Er3Al5O12 (EAG) eutectic ceramic was prepared via vertical Bridgman method with high-frequency induction heating. The effects of the growth rate on the microstructure and mechanical properties of the solidified ceramic were investigated. The experimental results showed that there were no pores or amorphous phases in the directionally solidified Al2O3/EAG eutectic ceramic. Al2O3 phase was embedded in the EAG matrix phase, and the two phases were intertwined with each other to form a typical binary eutectic "hieroglyphic" structure. With the increase of growth rate, the phase size and spacing of the solidified Al2O3/EAG ceramic both decreased, and the growth rate and phase spacing satisfied the lambda2v ~ 60 formula of Jackson-Hunt theory. The cross section microstructure of the solidified ceramic always exhibited an irregular eutectic growth, while the longitudinal section microstructure presented a directional growth. The mechanical properties of the solidified ceramic gradually increased with the increase of growth rate, and the maximum hardness and fracture toughness could reach 21.57 GPa and 2.98 MPa.m1/2 respectively. It was considered that the crack deflection and branching could enhance the toughness of the solidified ceramic effectively. PMID- 29601544 TI - Influence of Mothers' Nutrition Knowledge and Attitudes on Their Purchase Intention for Infant Cereal with No Added Sugar Claim. AB - A higher sugar intake in infancy might result in a predisposition to a higher sugar intake in later childhood. In Taiwan, many commercial infant and toddler foods with nutrition claims have high sugar content. This study explored the influence of mothers' knowledge and attitudes on their purchase intention for infant food with nutrition claims. This study was a cross-sectional survey. An online survey was distributed to 940 mothers who had a child aged between 4 months and 3 years; 40% of mothers tend to misunderstand that "no added sugar" (NAS) indicates no sugar or less sugar content and, thus, that NAS infant cereal is healthy. Approximately 50-70% of mothers believe that NAS infant cereal is more natural, healthier, and contains less sugar. Attitude toward the NAS claim was found to be a mediating variable between sugar-related knowledge and purchase intention. The lower the level of sugar-related knowledge was, the more positive the attitude toward NAS infant cereal and the higher the purchase intention for NAS infant cereal were. In the future, regulation of no added sugar is needed to avoid the misleading information and mothers' sugar-related knowledge need to be improved through nutrition education. PMID- 29601546 TI - Assessing Vulnerability to Urban Heat: A Study of Disproportionate Heat Exposure and Access to Refuge by Socio-Demographic Status in Portland, Oregon. AB - Extreme urban heat is a powerful environmental stressor which poses a significant threat to human health and well-being. Exacerbated by the urban heat island phenomenon, heat events are expected to become more intense and frequent as climate change progresses, though we have limited understanding of the impact of such events on vulnerable populations at a neighborhood or census block group level. Focusing on the City of Portland, Oregon, this study aimed to determine which socio-demographic populations experience disproportionate exposure to extreme heat, as well as the level of access to refuge in the form of public cooling centers or residential central air conditioning. During a 2014 heat wave, temperature data were recorded using a vehicle-traverse collection method, then extrapolated to determine average temperature at the census block group level. Socio-demographic factors including income, race, education, age, and English speaking ability were tested using statistical assessments to identify significant relationships with heat exposure and access to refuge from extreme heat. Results indicate that groups with limited adaptive capacity, including those in poverty and non-white populations, are at higher risk for heat exposure, suggesting an emerging concern of environmental justice as it relates to climate change. The paper concludes by emphasizing the importance of cultural sensitivity and inclusion, in combination with effectively distributing cooling centers in areas where the greatest burden befalls vulnerable populations. PMID- 29601547 TI - Impact of Interstitial Ni on the Thermoelectric Properties of the Half-Heusler TiNiSn. AB - TiNiSn is an intensively studied half-Heusler alloy that shows great potential for waste heat recovery. Here, we report on the structures and thermoelectric properties of a series of metal-rich TiNi1+ySn compositions prepared via solid state reactions and hot pressing. A general relation between the amount of interstitial Ni and lattice parameter is determined from neutron powder diffraction. High-resolution synchrotron X-ray powder diffraction reveals the occurrence of strain broadening upon hot pressing, which is attributed to the metastable arrangement of interstitial Ni. Hall measurements confirm that interstitial Ni causes weak n-type doping and a reduction in carrier mobility, which limits the power factor to 2.5-3 mW m-1 K-2 for these samples. The thermal conductivity was modelled within the Callaway approximation and is quantitively linked to the amount of interstitial Ni, resulting in a predicted value of 12.7 W m-1 K-1 at 323 K for stoichiometric TiNiSn. Interstitial Ni leads to a reduction of the thermal band gap and moves the peak ZT = 0.4 to lower temperatures, thus offering the possibility to engineer a broad ZT plateau. This work adds further insight into the impact of small amounts of interstitial Ni on the thermal and electrical transport of TiNiSn.

A pose estimation algorithm using only depth information is proposed in this paper. Foreground and background points are distinguished based on their relative positions with boundaries. Model templates are selected using synthetic scenes to make up for the point pair feature algorithm. An accurate and fast pose verification method is introduced to select result poses from thousands of poses. Our algorithm is evaluated against a large number of scenes and proved to be more accurate than algorithms using both color information and depth information. PMID- 29601550 TI - Exploration of the Use of New Psychoactive Substances by Individuals in Treatment for Substance Misuse in the UK. AB - Substance misuse services need to meet the growing demand and needs of individuals using new psychoactive substances (NPS). A review of the literature identified a paucity of research regarding NPS use by these individuals and UK guidelines outline the need for locally tailored strategies. The purpose of this qualitative study was to identify and explore key themes in relation to the use of NPS by individuals receiving community treatment for their substance use. Electronic records identified demographics and semi-structured interviews were undertaken. A thematic analysis of transcripts identified a variety of substance use histories; 50% were prescribed opiate substitutes and 25% used NPS as a primary substance. All were males, age range 26-59 years (SD = 9), who predominantly smoked cannabinoids and snorted/injected stimulant NPS. The type of NPS used was determined by affordability, availability, side-effect profile and desired effects (physical and psychological: 25% reported weight loss as motivation for their use). Poly-pharmacy, supplementation and displacement of other drugs were prevalent. In conclusion, NPS use and associated experiences vary widely among people receiving substance use treatment. Development of effective recovery pathways should be tailored to individuals, and include harm reduction strategies, psychosocial interventions, and effective signposting. Services should be vigilant for NPS use, "on top" use and diversion of prescriptions. PMID- 29601548 TI - Roles of NF-kappaB Signaling in the Regulation of miRNAs Impacting on Inflammation in Cancer. AB - The NF-kappaB family of transcription factors regulate the expression of genes encoding proteins and microRNAs (miRNA, miR) precursors that may either positively or negatively regulate a variety of biological processes such as cell cycle progression, cell survival, and cell differentiation. The NF-kappaB-miRNA transcriptional regulatory network has been implicated in the regulation of proinflammatory, immune, and stress-like responses. Gene regulation by miRNAs has emerged as an additional epigenetic mechanism at the post-transcriptional level. The expression of miRNAs can be regulated by specific transcription factors (TFs), including the NF-kappaB TF family, and vice versa. The interplay between TFs and miRNAs creates positive or negative feedback loops and also regulatory networks, which can control cell fate. In the current review, we discuss the impact of NF-kappaB-miRNA interplay and feedback loops and networks impacting on inflammation in cancer. We provide several paradigms of specific NF-kappaB-miRNA networks that can regulate inflammation linked to cancer. For example, the NF kappaB-miR-146 and NF-kappaB-miR-155 networks fine-tune the activity, intensity, and duration of inflammation, while the NF-kappaB-miR-21 and NF-kappaB-miR-181b-1 amplifying loops link inflammation to cancer; and p53- or NF-kappaB-regulated miRNAs interconnect these pathways and may shift the balance to cancer development or tumor suppression. The availability of genomic data may be useful to verify and find novel interactions, and provide a catalogue of 162 miRNAs targeting and 40 miRNAs possibly regulated by NF-kappaB. We propose that studying active TF-miRNA transcriptional regulatory networks such as NF-kappaB-miRNA networks in specific cancer types can contribute to our further understanding of the regulatory interplay between inflammation and cancer, and also perhaps lead to the development of pharmacologically novel therapeutic approaches to combat cancer. PMID- 29601551 TI - Kinetics and Thermodynamics of DNA Processing by Wild Type DNA-Glycosylase Endo III and Its Catalytically Inactive Mutant Forms. AB - Endonuclease III (Endo III or Nth) is one of the key enzymes responsible for initiating the base excision repair of oxidized or reduced pyrimidine bases in DNA. In this study, a thermodynamic analysis of structural rearrangements of the specific and nonspecific DNA-duplexes during their interaction with Endo III is performed based on stopped-flow kinetic data. 1,3-diaza-2-oxophenoxazine (tCO), a fluorescent analog of the natural nucleobase cytosine, is used to record multistep DNA binding and lesion recognition within a temperature range (5-37 degrees C). Standard Gibbs energy, enthalpy, and entropy of the specific steps are derived from kinetic data using Van't Hoff plots. The data suggest that enthalpy-driven exothermic 5,6-dihydrouracil (DHU) recognition and desolvation accompanied entropy-driven adjustment of the enzyme-substrate complex into a catalytically active state play equally important parts in the overall process. The roles of catalytically significant amino acids Lys120 and Asp138 in the DNA lesion recognition and catalysis are identified. Lys120 participates not only in the catalytic steps but also in the processes of local duplex distortion, whereas substitution Asp138Ala leads to a complete loss of the ability of Endo III to distort a DNA double chain during enzyme-DNA complex formation. PMID- 29601552 TI - Classification of Incomplete Data Based on Evidence Theory and an Extreme Learning Machine in Wireless Sensor Networks. AB - In wireless sensor networks, the classification of incomplete data reported by sensor nodes is an open issue because it is difficult to accurately estimate the missing values. In many cases, the misclassification is unacceptable considering that it probably brings catastrophic damages to the data users. In this paper, a novel classification approach of incomplete data is proposed to reduce the misclassification errors. This method uses the regularized extreme learning machine to estimate the potential values of missing data at first, and then it converts the estimations into multiple classification results on the basis of the distance between interval numbers. Finally, an evidential reasoning rule is adopted to fuse these classification results. The final decision is made according to the combined basic belief assignment. The experimental results show that this method has better performance than other traditional classification methods of incomplete data.

AB - In the light of modified the Matzinger's model of immune response, human heat shock proteins (hsp) as main 'danger signals' (tissue damage-associated molecular patterns-DAMPs) or/and microbial hsp as pathogen-associated molecular patterns (PAMPs) recognized by pattern recognition receptors (PRR), may induce sarcoid granuloma by both infectious and non-infectious factors in genetically different predisposed host. PMID- 29601553 TI - Dietary Patterns of Children and Adolescents from High, Medium and Low Human Development Countries and Associated Socioeconomic Factors: A Systematic Review. AB - The purpose of this systematic review is to assess the associations among education, income and dietary pattern (DP) in children and adolescents from high, medium and low human development countries (HHDC, MHDC and LHDC, respectively). Observational studies that evaluated the association between family income or education with the DP are obtained through electronic database searches. Forty articles are selected for review. In HHDC, education is inversely associated with "unhealthy" DP and positively associated with "healthy" DP. In cross-sectional studies from HHDC, higher income is negatively associated with "unhealthy" DP. In MHDC, there is no association between the socioeconomic variables (SE) and the DPs, although, in some studies, the unhealthy diet is positively associated with SE. Only one study conducted in LHDC showed an inverse association between income/education with "unhealthy" DP and there is no association between the SE and "healthy" DP. In conclusion, children and adolescents living in HHDC with high parental education tend to have a healthier diet. In MHDC, although an unhealthy diet is found among the high-income and educated population, the associations are not clear. Additional research is needed to clarify the associations between income and education with "unhealthy" and "healthy" DPs in MHDC and LHDC.

AB - In the light of modified the Matzinger's model of immune response, human heat shock proteins (hsp) as main "danger signals" tissue damage-associated molecular patterns (DAMPs) or/and microbial hsp as pathogen-associated molecular patterns (PAMPs) recognized by pattern recognition receptors (PRR), may induce sarcoid granuloma by both infectious and non-infectious factors in genetically different predisposed host. Regarding infectious causes of sarcoid models, low-virulence strains of, e.g. mycobacteria and propionibacteria recognized through genetically changed PRR and persisting in genetically altered host phagocytes, generate increased release of both human and microbial hsp with their molecular and functional homology. High chronic spread of human and microbial hsp altering cytokines, co-stimulatory molecules, and Tregs expression, apoptosis, oxidative stress, induces the autoimmunity, considered in sarcoidosis. Regarding non infectious causes of sarcoidosis, human hsp may be released at high levels during chronic low-grade exposure to misfolding amyloid precursor protein in stressed cells, phagocyted metal fumes, pigments with/ without aluminum in tattoos, and due to heat shock in firefighters. Therefore, human hsp as DAMPs and/or microbial hsp as PAMPs produced as a result of non-infectious and infectious factors may induce different models of sarcoidosis, depending on the genetic background of the host.

AB - Anaplastic Lymphoma Kinase (ALK)-positive Anaplastic Large Cell Lymphoma (ALCL), remains one of the most curable cancers in the paediatric setting; multi-agent chemotherapy cures approximately 65-90% of patients. Over the last two decades, major efforts have focused on improving the survival rate by intensification of combination chemotherapy regimens and employing stem cell transplantation for chemotherapy-resistant patients. More recently, several new and 'renewed' agents have offered the opportunity for a change in the paradigm for the management of both chemo-sensitive and chemo-resistant forms of ALCL. The development of ALK inhibitors following the identification of the EML4-ALK fusion gene in Non-Small Cell Lung Cancer (NSCLC) has opened new possibilities for ALK-positive ALCL. The uniform expression of CD30 on the cell surface of ALCL has given the opportunity for anti-CD30 antibody therapy. The re-evaluation of vinblastine, which has shown remarkable activity as a single agent even in the face of relapsed disease, has led to the consideration of a revised approach to frontline therapy. The advent of immune therapies such as checkpoint inhibition has provided another option for the treatment of ALCL. In fact, the number of potential new agents now presents a real challenge to the clinical community that must prioritise those thought to offer the most promise for the future. In this review, we will focus on the current status of paediatric ALCL therapy, explore how new and 'renewed' agents are re-shaping the therapeutic landscape for ALCL, and identify the strategies being employed in the next generation of clinical trials. PMID- 29601557 TI - [The diagnostic algorithm of practice in pulmonary and extrapulmonary sarcoidosis]. AB - Sarcoidosis (SA) is a granulomatous multisystem disease of unknown ethiology. Pulmonary, lymphadenopathy, liver, spleen, skin, and bone sarcoidosis are more frequent but also SA of the heart, central nervous system, eye, and hypercalcemia with following kidney failure also occur. Sarcoidosis may co-exist with extrapulmonary forms, which may overtake or precede each other. SA may occur as acute or chronic with the possibility of complete remission in the early stages of disease. Due to frequent occurrence of asymptomatic SA in threatening vital organs a diagnostic algorithm of practice in pulmonary and extrapulmonary sarcoidosis has been proposed by the author of the article. Diagnosis of SA is based on a correlation of clinical, radiological and histopathological pictures with the presence of non-caseating granuloma in material from the biopsy from at least one organ and having excluded tuberculosis. In all forms of SA, USG abdomen, ECG, ECHO heart, blood tests (blood count, calcium, creatinine, transaminases), level of calcium in a 24-hour urine samples, ophtalmoscopic examinations and lung function tests in pulmonary sarcoidosis should be undertaken to avoid overlooking any form of SA, especially in threatened vital organs. For this purpose, the multidisciplinary team providing an adequate care to the patient with SA has been created by the author of the article has been created by the author of the article in the University Clinical Center in Gdansk providing comprehensive care to patients with sarcoidosis. PMID- 29601558 TI - [Differentiation of dyspnea in patients with asthma and lung sarcoidosis]. AB - Dyspnea as a subjective feeling of lack of air is the patients with the pathology of the respiratory system. Objectivization of this phenomenon is difficult, despite the introduction of questionnaires about the degree of dyspnoea. The results of these assessments do not always correlate with the results of spirometric tests. In patients with asthma, dyspnoea is caused by airway obstruction. In the case of patients with lung sarcoidosis, the complexity of the phenomenon causes that many mechanisms and factors are responsible for the dyspnea symptoms in these patients. Dyspnea in patients with sarcoidosis is progressive and is closely related to the extent of interstitial exchanges. The diffusion capacity for carbon monoxide (DLco) determined in these patients reflects the degree of respiratory distress. Therapeutic procedures are also dependent on this parameter. PMID- 29601559 TI - [Advances in endoscopic diagnosis of sarcoidosis]. AB - A diagnosis of pulmonary sarcoidosis is based on the assessment of clinical outcome, radiology findings and detection of noncaseating granulomas in cytology or histology specimens. Cytological material obtained from enlarged lymph nodes and/or histological specimens from bronchial mucosa and lung tissue are examined according to sarcoidosis stage. The most available are standard bronchoscopic methods as conventional transbronchial needle aspiration (cTBNA), endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) both performed with use of forceps. The new endoscopic techniques introduced to pulmonary diagnostics are: endobronchial ultrasoundguided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) or if used by the ultrasound bronchoscope (EUS-b-FNA) and transbronchial lung cryobiopsy (TBLC). Considering a dynamic improvement in cytology assessment techniques (processed as cytology smears and cell blocks) the endoscopic methods with use of fine needle aspiration biopsy of enlarged lymph nodes became a method of choice in sarcoidosis with lymphadenopathy, and published data suggest a higher diagnostic yield when performed under endosonographic guidance. The optimal approach (transbronchial or transesophageal) and the selection of mediastinal lymph node stations considered for biopsy still need evaluation. Also TBLC, successfully used in the diagnosis of other diffuse parenchymal lung diseases, requires more experiences and trials to establish its role in diagnosis of pulmonary sarcoidosis. PMID- 29601560 TI - [Radiological examinations in the diagnosis and monitoring of pulmonary sarcoidosis]. AB - Diagnosis of sarcoidosis is mainly based on radiological examinations. The most important one is chest X-ray, which in typical cases reveals bilateral enlarged hilar lymph nodes, in a proportion of patients also concomitant parenchymal changes, rarely isolated parenchymal infiltrations or signs of lung fibrosis. The next step is chest computed tomography (CT), most often of high resolution, although strict indications for CT have been defined. Monitoring of sarcoidosis is based on the assessment of serial chest X-ray examinations. Indications for CT in a patient with completed diagnosis are limited. Positron emission tomography (PET) is a valuable tool for the evaluation of especially difficult diagnostic cases, for the assessment of disease activity, identification of yet unidentified extrapulmonary locations or selection of an optimal place for biopsy. In the present paper you will find how to use these radiological techniques for the diagnosis and monitoring of sarcoidosis. PMID- 29601561 TI - [Cardiac sarcoidosis: diagnostics, treatment and follow-up]. AB - Sarcoidosis is a generalised granulomatous disorder of unknown aetiology. Cardiac involvement may affect conduction system, myocardium, valvular apparatus and pericardium. Clinical spectrum ranges from asymptomatic involvement to sudden cardiac death. Patients with biopsy-proven extracardiac sarcoidosis should be screened for cardiac involvement (standard ECG, 24-hour Holter ECG, echocardiography) and in case of any abnormalities found on these tests, more advanced diagnostic methods should be used. Steroid treatment is still the mainstay of therapy in cardiac sarcoidosis. Several immunosuppresive agents are also effective and used in different combinations with steroids, as well as heart failure treatment (including ACE inhibitors, angiotensin receptor blockers, beta blockers and diuretics). Advanced heart block requires pacemaker implantation, and implantable cardioverterdefibrillator is an effective treatment in primary and secondary prophylaxis of sudden cardiac death. Heart transplantation is considered in advanced, drug-resistant heart failure or incessant ventricular arrhythmias unresponsive to other forms of therapy. PMID- 29601562 TI - [Neurosarcoidosis - diagnosis, clinical picture and therapy]. AB - Sarcoidosis (SA) is a granulomatous, multisystem disease of unknown etiology. Most often the disease affects lungs and mediastinal lymph nodes, but it may occur in other organs. Neurosarcoidosis (NS) more commonly occurs with other sarcoidosis forms, in 1% of cases it involves only nervous system. Symptomatic NS occurs but on autopsy study up to 25% of cases are confirmed. NS can affect central nervous system: the brain, spinal cord and peripheral nerves, and muscles. The diagnosis of neurosarcoidosis facilitates diagnostic criteria: histopathological, imaging and cerebrospinal fluid examination, and clinical symptoms. At present, there are no set standards for treatment of patients suffering from NS. Early therapy of symptomatic patients is recommended. Corticosteroids still are the first line of treatment for NS patients. In cases of steroids resistance, lack of their effectiveness or existence of contraindication to their use, immunosuppressant treatment is recommended. The latest NS algorithm with immunosuppressive treatment is discussed. PMID- 29601563 TI - [Advances in differential diagnosis and treatment of patients with sarcoidosis]. AB - The implementation of treatment in patients with sarcoidosis (SA) must be associated with the certainty of diagnosis, which is difficult due to the lack of unambiguous criteria. Finding the presence of noncaseating granulomas in bioptic material is not always indicative of SA. The main point of SA's diagnosis is the level of its activity, because only patients in the active stage should be qualified for treatment. In therapy, glucocorticosteroids or second-line drugs - methotrexate or azathioprine are still recommended. Introduced monoclonal antibodies (infliximab, etanercept, adaluimumab, golimumab, rituximab), tested for efficacy in other pathologies associated with the formation of granulomas, have a limited application in patients with SA. In contrast, anti-fibrotics (pirfenidone and nintedanib) are in clinical trials. The latest method of controlling the fibrosis of the parenchyma in the course of SA is the use of mesenchymal cells obtained from umbilical cord blood. Preliminary results indicate a real possibility of using this therapy in patients with SA. PMID- 29601564 TI - [Nintedanib in the treatment of fibrosing interstital lung diseases]. AB - Nintedanib is an intracellular tyrosine kinase inhibitor approved in a treatment of idiopathic pulmonary fibrosis. It reduces the annual rate of forced vital capacity decline by approximately 50%, that results in slowing of disease progression. The drug also reduces the incidence of acute exacerbations of idiopathic pulmonary fibrosis. The efficacy of nintedanib was the same in different groups of patients, irrespectively to disease status, age, gender and race. The most frequent side effects were gastrointestinal, i.e. diarrhea and nausea. If they occur symptomatic treatment should be implemented. In case of persistent symptoms despite of this, nintedanib dose should be decreased or drug interrupted. The research on combination therapy with pirfenidone did not show the new adverse drug reactions, there were no changes in pharmacokinetics of both drugs. A trend to improve the efficacy of the combination therapy in comparison to monotherapy with both drugs was noted, but further research in this field is needed. There are also trials of nintedanib in the treatment of other fibrosing interstitial lung diseases, i.e. chronic hypersensitivity pneumonitis, stage IV sarcoidosis or connective tissue disease related lung disorders. PMID- 29601565 TI - [Cutaneous sarcoidosis - a great imitator]. AB - Skin manifestation occurs in approximately 25% of patients with sarcoidosis and is often the first symptom of the disease. The availability of skin biopsy material is helpful in establishing the early diagnosis. Cutaneous sarcoidosis is characterized by clinical polymorphism and therefore its diagnosis may cause dilemma. The systemic sarcoidosis should be excluded in every patient with cutaneous sarcoidosis, because systemic involvement has a significant impact on course, treatment and prognosis of the disease. PMID- 29601566 TI - [Disturbances of calcium metabolism and vitamin D supplementation in sarcoidosis two-way street]. AB - The role of vitamin D in the human body is not limited only to the regulation of calcium metabolism and secondary to the impact on bones. Recent studies have shown the influence of vitamin D level on muscles, on the risk of cancer, diabetes, hypertension and pulmonary diseases, including granulomatous diseases. Sarcoidosis is a granulomatous disease of unknown etiology. Hypercalcemia in the course of the disease occurs in up to 10% of cases in the consequence of autonomous overproduction of 1,25-dihydroxyvitamin D by macrophages of sarcoid granulomas. Hypercalciuria occurs 3-fold more frequent. On the other hand, treatment with corticosteroids increases the risk of osteoporosis. Vitamin D intake is recommended for prevention of osteoporosis. Such management, in sarcoidosis patients, is not so clear because of risk of hypercalcemia. Vitamin D supplementation, according to current recommendations for general population, is based solely on 25-hydroxyvitamin D level testing. This seems to be not safe in the group of sarcoidosis patients. This article discusses the role of vitamin D in sarcoidosis patients and current opinion on vitamin D supplementation in this group. PMID- 29601567 TI - [Rehabilitation of patients with sarcoidosis]. AB - Comprehensive rehabilitation programs have so far been developed for many chronic diseases. It has been proven that their use can be safe and effective in lung diseases such as chronic obstructive pulmonary disease. There are still no standards of rehabilitation in the group of patients with sarcoidosis available. This situation results mainly from a small number of large, randomized studies concerning this topic. The available literature, however, allows defining some general rules in this field. It also provides evidence for the effectiveness of rehabilitation in reducing symptoms, improving the quality of life and prognosis in patients with sarcoidosis. Interventions such as endurance and strength training, including inspiratory muscle training, have been applied. Further research is necessary to confirm these data.

AB - Hypersensitivity pneumonitis (HP), called extrinsic allergic alveolitis, is a syndrome characterized by diffuse inflammation of lung parenchyma and airways in response to the inhalation of antigens to witch the patient has been previously sensitized. The clinical presentation of HP have been categorized as acute, subacute and chronic. The patient with chronic HP may lack a history of acute episodes and usually reports the insidious onset of cough, dyspnoea, fatigue, and weight los. Idiopathic pulmonary fibrosis (IPF) is a type of lung disease that results in scarring (fibrosis) of the lungs for an unknown reason. Symptoms of IPF are the same as in chronic hypersensitivity pneumonitis and differentiation may be difficult. We present a case of patient with chronic HP, in whom the course of the end stage of the disease mimic acute exacerbations idiopathic pulmonary fibrosis. PMID- 29601569 TI - Anthropometric Indices Predict the Development of Hypertension in Normotensive and Pre-Hypertensive Middle-Aged Women in Tianjin, China: A Prospective Cohort Study. AB - BACKGROUND The aims of this study were to investigate the relationship between optimal anthropometric indices and their cut-off values and the incidence of hypertension in a cohort of middle-aged women in China. MATERIAL AND METHODS A cohort of 812 women, aged between 40-70 years were recruited between May 2011 and June 2013. An ideal baseline blood pressure was defined as <120/80 mmHg; pre hypertension was 120-139/80-89 mmHg; hypertension was >=140/>=90 mmHg. Anthropometric measurements included waist circumference (WC), body mass index (BMI), waist-hip ratio (WHR), and waist-height ratio (WHtR). The cohort was divided into an ideal blood pressure group (Group 1) and a pre-hypertensive group (Group 2). Two-year follow-up blood pressure measurements were performed. Receiver-operating characteristic (ROC) curve analysis determined the optimal anthropometric indices and cut-off values for developing hypertension. RESULTS At two-year follow-up, hypertension developed in 9.0% (n=31) in Group 1 and 32.3% (n=121) in Group 2. Logistic regression analysis showed that in both groups, women in the highest quartile for WC, BMI, WHR, and WHtR had a significantly increased risk of developing hypertension compared with the lowest quartile (P<0.05). ROC curve area under the curve (AUC) for these anthropometric indices were greater in Group 1, and for WC in Groups 1 and 2, with the optimal cut-off values greater in Group 1. CONCLUSIONS In a cohort of middle-aged women in China, anthropometric indices of obesity were predictive of the development of hypertension during a two-year follow-up period. PMID- 29601570 TI - Integration of postpartum healthcare services for HIV-infected women and their infants in South Africa: A randomised controlled trial. AB - BACKGROUND: As the number of HIV-infected women initiating lifelong antiretroviral therapy (ART) during pregnancy increases globally, concerns have emerged regarding low levels of retention in HIV services and suboptimal adherence to ART during the postpartum period. We examined the impact of integrating postpartum ART for HIV+ mothers alongside infant follow-up within maternal and child health (MCH) services in Cape Town, South Africa. METHODS AND FINDINGS: We conducted a randomised trial among HIV+ postpartum women aged >=18 years who initiated ART during pregnancy in the local antenatal care clinic and were breastfeeding when screened before 6 weeks postpartum. We compared an integrated postnatal service among mothers and their infants (the MCH-ART intervention) to the local standard of care (control)-immediate postnatal referral of HIV+ women on ART to general adult ART services and their infants to separate routine infant follow-up. Evaluation data were collected through medical records and trial measurement visits scheduled and located separately from healthcare services involved in either arm. The primary trial outcome was a composite endpoint of women's retention in ART care and viral suppression (VS) (viral load < 50 copies/ml) at 12 months postpartum; secondary outcomes included duration of any and exclusive breastfeeding, mother-to-child HIV transmission, and infant mortality. Between 5 June 2013 and 10 December 2014, a total of 471 mother-infant pairs were enrolled and randomised (mean age, 28.6 years; 18% nulliparous; 57% newly diagnosed with HIV in pregnancy; median duration of ART use at randomisation, 18 weeks). Among 411 women (87%) with primary endpoint data available, 77% of women (n = 155) randomised to the MCH-ART intervention achieved the primary composite outcome of retention in ART services with VS at 12 months postpartum, compared to 56% of women (n = 117) randomised to the control arm (absolute risk difference, 0.21; 95% CI: 0.12-0.30; p < 0.001). The findings for improved retention in care and VS among women in the MCH-ART intervention arm were consistent across subgroups of participants according to demographic and clinical characteristics. The median durations of any breastfeeding and exclusive breastfeeding were longer in women randomised to the intervention versus control arm (6.9 versus 3.0 months, p = 0.006, and 3.0 versus 1.4 months, p < 0.001, respectively). For the infants, overall HIV-free survival through 12 months of age was 97%: mother-to-child HIV transmission was 1.2% overall (n = 4 and n = 1 transmissions in the intervention and control arms, respectively), and infant mortality was 1.9% (n = 6 and n = 3 deaths in the intervention and control arms, respectively), and these outcomes were similar by trial arm. Interpretation of these findings should be qualified by the location of this study in a single urban area as well as the self-reported nature of breastfeeding outcomes. CONCLUSIONS: In this study, we found that integrating ART services into the MCH platform during the postnatal period was a simple and effective intervention, and this should be considered for improving maternal and child outcomes in the context of HIV. TRIAL REGISTRATION: ClinicalTrials.gov NCT01933477. PMID- 29601571 TI - The presence of rNTPs decreases the speed of mitochondrial DNA replication. AB - Ribonucleotides (rNMPs) are frequently incorporated during replication or repair by DNA polymerases and failure to remove them leads to instability of nuclear DNA (nDNA). Conversely, rNMPs appear to be relatively well-tolerated in mitochondrial DNA (mtDNA), although the mechanisms behind the tolerance remain unclear. We here show that the human mitochondrial DNA polymerase gamma (Pol gamma) bypasses single rNMPs with an unprecedentedly high fidelity and efficiency. In addition, Pol gamma exhibits a strikingly low frequency of rNMP incorporation, a property, which we find is independent of its exonuclease activity. However, the physiological levels of free rNTPs partially inhibit DNA synthesis by Pol gamma and render the polymerase more sensitive to imbalanced dNTP pools. The characteristics of Pol gamma reported here could have implications for forms of mtDNA depletion syndrome (MDS) that are associated with imbalanced cellular dNTP pools. Our results show that at the rNTP/dNTP ratios that are expected to prevail in such disease states, Pol gamma enters a polymerase/exonuclease idling mode that leads to mtDNA replication stalling. This could ultimately lead to mtDNA depletion and, consequently, to mitochondrial disease phenotypes such as those observed in MDS. PMID- 29601572 TI - Brugia malayi infection in ferrets - A small mammal model of lymphatic filariasis. AB - BACKGROUND: The lack of effective short-course therapies for treatment of the adult stage of filarial worms is a major limitation in the global effort to eliminate lymphatic filariasis. Studies using current small mammal models of lymphatic filariasis are limited by difficulties in quantifying adult worm numbers and in assessing lymphatic anatomy and function. METHODOLOGY/PRINCIPAL FINDINGS: Here, we re-established Brugia malayi infection of ferrets as a model for lymphatic filariasis and demonstrated parasitological, immunological, and histological parallels with human infection. Subcutaneous injection of L3 larvae into a hind-footpad resulted in a mean of 18 adult worms recovered 16 weeks post infection, primarily from the draining inguinal and femoral lymphatics of the injected limb. Infected ferrets developed microfilaremia, with patency lasting from 12-26 weeks post-infection. Quantitative PCR assessing cytokine transcription by antigen-stimulated lymph node cells demonstrated a mixed Th1/Th2 response occurring during early infection. Immunoregulation with production of down-regulatory cytokine IL-10 occurred just prior to peak microfilaremia. Histological analysis revealed progressive inflammation of the lymphatic vessel walls, with intimal thickening and disorganization of collagen fibers. Inflammation was observed as early as 8 weeks post-infection and extended into the perivascular and subcutaneous tissues by 16 weeks post-infection. Finally, we developed a novel ferret PET/CT lymphoscintigraphy method demonstrating substantial changes in lymphatic anatomy and function as early as 3 weeks post infection, with progression over the course of infection. CONCLUSIONS/SIGNIFICANCE: B. malayi infection of ferrets is a robust model of human lymphatic filariasis that can be utilized to study efficacy of novel antifilarial agents against adult worms residing within lymphatic vessels. In conjunction with PET/CT lymphoscintigraphy, this model can also be used to investigate pathogenesis of lymphatic dysfunction in lymphatic filariasis and efficacy of medications aimed at reversing lymphatic dysfunction after clearance of adult worms. PMID- 29601573 TI - Ten years of surveillance of the Yulong plague focus in China and the molecular typing and source tracing of the isolates. AB - Plague, caused by Yersinia pestis, was classified as a reemerging infectious disease by the World Health Organization. The five human pneumonic plague cases in Yulong County in 2005 gave rise to the discovery of a Yulong plague focus in Yunnan province, China. Thereafter, continuous wild rodent plague (sylvatic plague) was identified as the main plague reservoir of this focus. In this study, the epizootics in Yulong focus were described, and three molecular typing methods, including the different region (DFR) analysis, clustered regularly interspaced short palindromic repeats (CRISPRs), and the multiple-locus variable number of tandem repeats (VNTR) analysis (MLVA) (14+12), were used for the molecular typing and source tracing of Y. pestis isolates in the Yulong plague focus. Simultaneously, several isolates from the vicinity of Yunnan were used as controls. The results showed that during the 10-year period from 2006 to 2016, an animal plague epidemic occurred in 6 of those years, and 5 villages underwent an animal plague epidemic within a 30-km2 area of the Yulong plague focus. Searching for dead mice was the most effective monitoring method in this plague focus. No positive sample has been found in 6937 captured live rodents thus far, suggesting that the virulence of strains in the Yulong plague focus is stronger and the survival time of mice is shorter after infection. Strains from Lijiang, Sichuan and Tibet were of the same complex based on a typing analysis of DFR and CRISPR. The genetic relationship of Y. pestis illustrated by MLVA "14+12" demonstrates that Tibet and Sichuan strains evolved from the strains 1.IN2 (Qinghai, 1970 and Tibet, 1976), and Lijiang strains are closer to Batang strains (Batang County in Sichuan province, 2011, Himalaya marmot plague foci) in terms of genetic or phylogenic relationships. In conclusion, we have a deeper understanding of this new plague focus throughout this study, which provides a basis for effective prevention and control. PMID- 29601574 TI - Dynamic frontotemporal systems process space and time in working memory. AB - How do we rapidly process incoming streams of information in working memory, a cognitive mechanism central to human behavior? Dominant views of working memory focus on the prefrontal cortex (PFC), but human hippocampal recordings provide a neurophysiological signature distinct from the PFC. Are these regions independent, or do they interact in the service of working memory? We addressed this core issue in behavior by recording directly from frontotemporal sites in humans performing a visuospatial working memory task that operationalizes the types of identity and spatiotemporal information we encounter every day. Theta band oscillations drove bidirectional interactions between the PFC and medial temporal lobe (MTL; including the hippocampus). MTL theta oscillations directed the PFC preferentially during the processing of spatiotemporal information, while PFC theta oscillations directed the MTL for all types of information being processed in working memory. These findings reveal an MTL theta mechanism for processing space and time and a domain-general PFC theta mechanism, providing evidence that rapid, dynamic MTL-PFC interactions underlie working memory for everyday experiences. PMID- 29601576 TI - Topographic effects on dispersal patterns of Phytophthora cinnamomi at a stand scale in a Spanish heathland. AB - Phytophthora cinnamomi is one of the most important plant pathogens in the world, causing root rot in more than a thousand plant species. This observational study was carried out on a P. cinnamomi infected heathland of Erica umbellata used as goat pasture. The patterns and shapes of disease foci and their distribution were described in a spatial and temporal context using an aerial photograph record. A set of topographic traits was selected on the basis of a disease dynamic hypothesis and their effects on observed spatial disease patterns were analyzed. Incipient infections situated in flat terrain expanded as compact circular front patterns with a low growth rate. On slopes, disease patches developed more rapidly down slope, forming parabolic shapes. The axis direction of the parabolas was highly correlated with terrain aspect, while the parabolic amplitude was associated with land curvature and slope. New secondary foci appeared over the years producing an accelerated increase of the affected surface. These new foci were observed in sites where disease density was higher or near sites more frequently visited by animals such as the stable or the forage crop. In contrast, a smaller number of disease foci occur in areas which animals are reluctant to visit, such as where they have a short range of vision. Our results suggest that 1) the growth of existing P. cinnamomi foci is controlled by a combination of root-to-root contact and water flows, 2) the increase in the diseased area arises mainly from the multiplication of patches, 3) the formation of new foci is mediated by long-distance transport due to the movement of animals and humans along certain preferential pathways, and 4) geomorphology and topography traits are associated with the epidemiology of this soil-borne pathogen. PMID- 29601575 TI - Discovery of genomic intervals that underlie nematode responses to benzimidazoles. AB - Parasitic nematodes impose a debilitating health and economic burden across much of the world. Nematode resistance to anthelmintic drugs threatens parasite control efforts in both human and veterinary medicine. Despite this threat, the genetic landscape of potential resistance mechanisms to these critical drugs remains largely unexplored. Here, we exploit natural variation in the model nematodes Caenorhabditis elegans and Caenorhabditis briggsae to discover quantitative trait loci (QTL) that control sensitivity to benzimidazoles widely used in human and animal medicine. High-throughput phenotyping of albendazole, fenbendazole, mebendazole, and thiabendazole responses in panels of recombinant lines led to the discovery of over 15 QTL in C. elegans and four QTL in C. briggsae associated with divergent responses to these anthelmintics. Many of these QTL are conserved across benzimidazole derivatives, but others show drug and dose specificity. We used near-isogenic lines to recapitulate and narrow the C. elegans albendazole QTL of largest effect and identified candidate variants correlated with the resistance phenotype. These QTL do not overlap with known benzimidazole target resistance genes from parasitic nematodes and present specific new leads for the discovery of novel mechanisms of nematode benzimidazole resistance. Analyses of orthologous genes reveal conservation of candidate benzimidazole resistance genes in medically important parasitic nematodes. These data provide a basis for extending these approaches to other anthelmintic drug classes and a pathway towards validating new markers for anthelmintic resistance that can be deployed to improve parasite disease control. PMID- 29601577 TI - An open source tool for automatic spatiotemporal assessment of calcium transients and local 'signal-close-to-noise' activity in calcium imaging data. AB - Local and spontaneous calcium signals play important roles in neurons and neuronal networks. Spontaneous or cell-autonomous calcium signals may be difficult to assess because they appear in an unpredictable spatiotemporal pattern and in very small neuronal loci of axons or dendrites. We developed an open source bioinformatics tool for an unbiased assessment of calcium signals in x,y-t imaging series. The tool bases its algorithm on a continuous wavelet transform-guided peak detection to identify calcium signal candidates. The highly sensitive calcium event definition is based on identification of peaks in 1D data through analysis of a 2D wavelet transform surface. For spatial analysis, the tool uses a grid to separate the x,y-image field in independently analyzed grid windows. A document containing a graphical summary of the data is automatically created and displays the loci of activity for a wide range of signal intensities. Furthermore, the number of activity events is summed up to create an estimated total activity value, which can be used to compare different experimental situations, such as calcium activity before or after an experimental treatment. All traces and data of active loci become documented. The tool can also compute the signal variance in a sliding window to visualize activity-dependent signal fluctuations. We applied the calcium signal detector to monitor activity states of cultured mouse neurons. Our data show that both the total activity value and the variance area created by a sliding window can distinguish experimental manipulations of neuronal activity states. Notably, the tool is powerful enough to compute local calcium events and 'signal-close-to-noise' activity in small loci of distal neurites of neurons, which remain during pharmacological blockade of neuronal activity with inhibitors such as tetrodotoxin, to block action potential firing, or inhibitors of ionotropic glutamate receptors.

AB - Interleukin-18 (IL-18) is a pleiotropic cytokine of the IL-1 family with multiple context dependent functions. We and others have shown that HIV infection is accompanied by increased circulating levels of IL-18 along with decreased levels of its antagonist, Interleukin-18 Binding Protein (IL-18BP). The infection is also accompanied by intestinal inflammation and decreased intestinal integrity as measured by intestinal permeability, regeneration and repair. However, little is known concerning the relation between high level of IL-18 associated with the viral infection and intestinal permeability. Here we demonstrate that HIV treatment increases production of IL-18 and decreases that of IL-18BP production in human intestinal epithelial cell (IEC) lines. IL-18 causes apoptosis of the IEC by activating caspase-1 and caspase-3. It induces epithelial barrier hyperpermeability by decreasing and disrupting both tight and adherens junction proteins, occludin, claudin 2 and beta-catenin. Disorganization of F-actin was also observed in the IEC that were exposed to the cytokine. Moreover IL-18 decreases transepithelial electrical resistance (TEER) in Caco-2 and increases permeability in HT29 monolayers. The cells' treatment with IL-18 causes an increase in the expression of phosphorylated myosin II regulatory light-chain (p MLC) and myosin light-chain kinase (MLCK), and a decrease in phosphorylated Signal Transducer and Activator of Transcription (p-STAT)-5. This increase in p MLC is suppressed by a Rho-kinase (ROCK)-specific inhibitor. Interestingly, the levels of the cytokine correlate with those of LPS in the circulation in three different categories of HIV infected patients (HAART-naive and HAART-treated HIV infected individuals, and Elite controls) as well as in healthy controls. Collectively, these results suggest that the HIV-induced IL-18 plays a role in increased intestinal permeability and microbial translocation observed in HIV infected individuals.

AB - Deposition of additional plasma membrane and cargoes during cytokinesis in eukaryotic cells must be coordinated with actomyosin ring contraction, plasma membrane ingression and extracellular matrix remodelling. The process by which the secretory pathway promotes specific incorporation of key factors into the cytokinetic machinery is poorly understood. Here, we show that cell polarity protein Spa2 interacts with actomyosin ring components during cytokinesis. Spa2 directly binds to cytokinetic factors Cyk3 and Hof1. The lethal effects of deleting the SPA2 gene in the absence of either Cyk3 or Hof1 can be suppressed by expression of the hypermorphic allele of the essential chitin synthase II (Chs2), a transmembrane protein transported on secretory vesicles that makes the primary septum during cytokinesis. Spa2 also interacts directly with the chitin synthase Chs2. Interestingly, artificial incorporation of Chs2 into the cytokinetic machinery allows the localisation of Spa2 at the site of division. In addition, increased Spa2 protein levels promote Chs2 incorporation at the site of division and primary septum formation. Our data indicate that Spa2 is recruited to the cleavage site to co-operate with the secretory vesicle system and particular actomyosin ring components to promote the incorporation of Chs2 into the so called 'ingression progression complexes' during cytokinesis in budding yeast. PMID- 29601580 TI - Pyrethroid resistance persists after ten years without usage against Aedes aegypti in governmental campaigns: Lessons from Sao Paulo State, Brazil. AB - BACKGROUND: Aedes aegypti, vector of dengue, chikungunya and Zika viruses, is found at high densities in tropical urban areas. The dissemination of this vector is partially the consequence of failures in current vector control methods, still mainly relying upon insecticides. In the State of Sao Paulo (SP), Brazil, public health managers employed pyrethroids against Ae. aegypti adults from 1989 to 2000, when a robust insecticide resistance monitoring system detected resistance to pyrethroids in several Ae. aegypti populations. However, pyrethroids are also the preferred compounds engaged in household applications due to their rapid knockdown effect, lower toxicity to mammals and less irritating smell. METHODOLOGY/PRINCIPAL FINDINGS: We evaluated pyrethroid resistance in Ae. aegypti populations over the course of a decade, from 2004 to 2015, after interruption of pyrethroid public applications in SP. Qualitative bioassays with papers impregnated with a deltamethrin diagnostic dose (DD) performed with insects from seven SP municipalities and evaluated yearly from 2006 to 2014, detected resistance in most of the cases. Quantitative bioassays were also carried out with four populations in 2011, suggesting a positive correlation between resistance level and survivorship in the DD bioassays. Biochemical tests conducted with seven insect populations in 2006 and 2015, detected increasing metabolic alterations of all major classes of detoxifying enzymes, mostly of mixed function oxidases. Genotyping of the voltage-gated sodium channel (AaNaV, the pyrethroid target-site) with a TaqMan real time PCR based technique was performed from 2004 to 2014 in all seven localities. The two kdr mutations, Val1016Ile and Phe1534Cys, known to be spread throughout Brazil, were always present with a severe decrease of the susceptible allele over time. CONCLUSIONS/SIGNIFICANCE: These results are discussed in the context of public and domestic insecticide use, the necessity of implementation of a strong integrated vector control strategy and the conceptual misunderstanding between 'vector control' and 'chemical control of vectors'. PMID- 29601581 TI - Widespread domain-like perturbations of DNA methylation in whole blood of Down syndrome neonates. AB - INTRODUCTION: Down syndrome (DS) is the most frequent genetic cause of intellectual disability. Despite the fact that more than 50 years have passed since the discovery of its genetic aberrations, the exact pathogenesis of the DS phenotype has remained largely unexplained. It was recently hypothesized that the DS pathogenesis involves complex (epi)genetic, molecular and cellular determinants. To date, many reports have addressed epigenetic aberrations associated with DS at different developmental stages/ages and tissue types, but to our best knowledge not in DS newborns. This study aimed to investigate genome wide methylation patterns in DS newborns compared to non-trisomic newborns. METHOD: We analyzed blood samples obtained from ten newborns with DS and five age matched non-trisomic newborns. Epigenetic profiles were obtained from extracted DNA using the Illumina Infinium 450K array. Since aberrant blood cell distribution is known to be present in DS, we applied two distinct models: with and without correction for estimated blood cell distribution. RESULTS: Differentially methylated position (DMP) analysis of the uncorrected model detected 19525 significant hits (51,2% hypomethylated). In the corrected model, we found 121953 significant DMPs (49,8% hypomethylated). Independent of the used model we observed a chromosome 21 dosage effect. Moreover, we detected 46 and 145 differentially methylated regions in the uncorrected and corrected model respectively, both showing hypomethylation overrepresentation. Replication analyses of DMPs and DMRs found by Bacalini et al. (2015) showed a large overlap. CONCLUSION: In this study, we found methylation profile differences between DS newborns and controls reflecting a systematically affected epigenetic profile. The observed chromosome 21 dosage effect suggests the involvement of affected essential regulatory factors/regions or altered expression of chromatin modeling enzymes located on chromosome 21. Additional research is necessary to substantiate these hypotheses. PMID- 29601582 TI - Cardiovascular disease: The rise of the genetic risk score. AB - In a Perspective, Joshua Knowles and Euan Ashley discuss the potential for use of genetic risk scores in clinical practice. PMID- 29601583 TI - Chronic restraint stress induces excessive activation of primordial follicles in mice ovaries. AB - Chronic stress is an important factor influencing people's health. It usually causes endocrinal disorders and a decline in reproduction in females. Although studies of both human and animals suggest a detrimental effect of stress on reproduction, the influence of chronic stress on the ovarian reservation and follicular development is still not clear. In this study, a chronic restraint stress (CRS) mouse model was used to investigate the effect of stress on ovarian reservation and follicular development and explore the underlying mechanism. In this study, after 8 weeks of CRS, primordial follicles were excessively activated in the ovaries of the CRS group compared with the control group. Further results showed that the activation of primordial follicles induced by CRS was involved in the increasing expression level of Kit ligand and its receptor Kit and the activation of phosphatidylinositol 3-kinase (PI3K)/phosphatase and tensin homolog deleted on chromosome 10 (PTEN)/protein kinase B (Akt) pathway. The corticotropin releasing hormone (CRH) is a neuropeptide released due to stress, which plays an important role in regulating follicle development. A high level of serum CRH was detected in the CRS mouse model, and the real-time polymerase chain reaction assay showed that the mRNA level of its main receptor CRHR1increased in the ovaries of the CRS mouse group. Moreover, 100nM CRH significantly improved the activation of primordial follicles in newborn mouse ovaries in vitro. These results demonstrated that CRS could induce immoderate activation of primordial follicles accompanied by the activation of Kit-PI3K signaling, in which CRH might be an important endocrine factor. PMID- 29601584 TI - 2'-O-methylation of the mRNA cap protects RNAs from decapping and degradation by DXO. AB - The 5' RNA cap structure (m7GpppRNA) is a key feature of eukaryotic mRNAs with important roles in stability, splicing, polyadenylation, mRNA export, and translation. Higher eukaryotes can further modify this minimal cap structure with the addition of a methyl group on the ribose 2'-O position of the first transcribed nucleotide (m7GpppNmpRNA) and sometimes on the adjoining nucleotide (m7GpppNmpNmpRNA). In higher eukaryotes, the DXO protein was previously shown to be responsible for both decapping and degradation of RNA transcripts harboring aberrant 5' ends such as pRNA, pppRNA, GpppRNA, and surprisingly, m7GpppRNA. It was proposed that the interaction of the cap binding complex with the methylated cap would prevent degradation of m7GpppRNAs by DXO. However, the critical role of the 2'-O-methylation found in higher eukaryotic cap structures was not previously addressed. In the present study, we demonstrate that DXO possesses both decapping and exoribonuclease activities toward incompletely capped RNAs, only sparing RNAs with a 2'-O-methylated cap structure. Fluorescence spectroscopy assays also revealed that the presence of the 2'-O-methylation on the cap structure drastically reduces the affinity of DXO for RNA. Moreover, immunofluorescence and structure-function assays also revealed that a nuclear localisation signal is located in the amino-terminus region of DXO. Overall, these results are consistent with a quality control mechanism in which DXO degrades incompletely capped RNAs. PMID- 29601585 TI - Trypanosoma cruzi 80 kDa prolyl oligopeptidase (Tc80) as a novel immunogen for Chagas disease vaccine. AB - BACKGROUND: Chagas disease, also known as American Trypanosomiasis, is a chronic parasitic disease caused by the flagellated protozoan Trypanosoma cruzi that affects about 8 million people around the world where more than 25 million are at risk of contracting the infection. Despite of being endemic on 21 Latin-American countries, Chagas disease has become a global concern due to migratory movements. Unfortunately, available drugs for the treatment have several limitations and they are generally administered during the chronic phase of the infection, when its efficacy is considered controversial. Thus, prophylactic and/or therapeutic vaccines are emerging as interesting control alternatives. In this work, we proposed Trypanosoma cruzi 80 kDa prolyl oligopeptidase (Tc80) as a new antigen for vaccine development against Chagas disease. METHODOLOGY/PRINCIPAL FINDINGS: In a murine model, we analyzed the immune response triggered by different immunization protocols based on Tc80 and evaluated their ability to confer protection against a challenge with the parasite. Immunized mice developed Tc80 specific antibodies which were able to carry out different functions such as: enzymatic inhibition, neutralization of parasite infection and complement mediated lysis of trypomastigotes. Furthermore, vaccinated mice elicited strong cell-mediated immunity. Spleen cells from immunized mice proliferated and secreted Th1 cytokines (IL-2, IFN-gamma and TNF-alpha) upon re-stimulation with rTc80. Moreover, we found Tc80-specific polyfunctional CD4 T cells, and cytotoxic T lymphocyte activity against one Tc80 MHC-I peptide. Immunization protocols conferred protection against a T. cruzi lethal challenge. Immunized groups showed a decreased parasitemia and higher survival rate compared with non-immunized control mice. Moreover, during the chronic phase of the infection, immunized mice presented: lower levels of myopathy-linked enzymes, parasite burden, electrocardiographic disorders and inflammatory cells. CONCLUSIONS/SIGNIFICANCE: Considering that an early control of parasite burden and tissue damage might contribute to avoid the progression towards symptomatic forms of chronic Chagas disease, the efficacy of Tc80-based vaccines make this molecule a promising immunogen for a mono or multicomponent vaccine against T. cruzi infection. PMID- 29601587 TI - Controlling and synchronizing a fractional-order chaotic system using stability theory of a time-varying fractional-order system. AB - Control and synchronization of fractional-order chaotic systems have attracted wide attention due to their numerous potential applications. To get suitable control method and parameters for fractional-order chaotic systems, the stability analysis of time-varying fractional-order systems should be discussed in the first place. Therefore, this paper analyzes the stability of the time-varying fractional-order systems and presents a stability theorem for the system with the order 0=1 laboratory recorded in eHARS post-release. Among the intervention group, 52% were retained in care (i.e., had two laboratory studies, > = 3 months apart), versus 40% among the comparison group (OR = 1.60, 95% CI (0.71, 3.81)). Both arms showed improved viral load suppression. CONCLUSIONS: There was a trend towards increased retention for PLWH released from jail after SUCCESS, compared to usual services. Measuring linkage at all venues, including jail-based clinics, fully captured engagement for this frequently recidivating population. TRIAL REGISTRATION: ClinicalTrials.gov NCT02185742. PMID- 29601592 TI - No significant regulation of bicoid mRNA by Pumilio or Nanos in the early Drosophila embryo. AB - Drosophila Pumilio (Pum) is a founding member of the conserved Puf domain class of RNA-binding translational regulators. Pum binds with high specificity, contacting eight nucleotides, one with each of the repeats in its RNA-binding domain. In general, Pum is thought to block translation in collaboration with Nanos (Nos), which exhibits no binding specificity in isolation but is recruited jointly to regulatory sequences containing a Pum binding site in the 3'-UTRs of target mRNAs. Unlike Pum, which is ubiquitous in the early embryo, Nos is tightly restricted to the posterior, ensuring that repression of its best-characterized target, maternal hunchback (hb) mRNA, takes place exclusively in the posterior. An exceptional case of Nos-independent regulation by Pum has been described repression of maternal bicoid (bcd) mRNA at the anterior pole of the early embryo, dependent on both Pum and conserved Pum binding sites in the 3'-UTR of the mRNA. We have re-investigated regulation of bcd in the early embryo; our experiments reveal no evidence of a role for Pum or its conserved binding sites in regulation of the perdurance of bcd mRNA or protein. Instead, we find that Pum and Nos control the accumulation of bcd mRNA in testes. PMID- 29601593 TI - A sensitive and innovative detection method for rapid C-reactive proteins analysis based on a micro-fluxgate sensor system. AB - A sensitive and innovative assay system based on a micro-MEMS-fluxgate sensor and immunomagnetic beads-labels was developed for the rapid analysis of C-reactive proteins (CRP). The fluxgate sensor presented in this study was fabricated through standard micro-electro-mechanical system technology. A multi-loop magnetic core made of Fe-based amorphous ribbon was employed as the sensing element, and 3-D solenoid copper coils were used to control the sensing core. Antibody-conjugated immunomagnetic microbeads were strategically utilized as signal tags to label the CRP via the specific conjugation of CRP to polyclonal CRP antibodies. Separate Au film substrates were applied as immunoplatforms to immobilize CRP-beads labels through classical sandwich assays. Detection and quantification of the CRP at different concentrations were implemented by detecting the stray field of CRP labeled magnetic beads using the newly-developed micro-fluxgate sensor. The resulting system exhibited the required sensitivity, stability, reproducibility, and selectivity. A detection limit as low as 0.002 MUg/mL CRP with a linearity range from 0.002 MUg/mL to 10 MUg/mL was achieved, and this suggested that the proposed biosystem possesses high sensitivity. In addition to the extremely low detection limit, the proposed method can be easily manipulated and possesses a quick response time. The response time of our sensor was less than 5 s, and the entire detection period for CRP analysis can be completed in less than 30 min using the current method. Given the detection performance and other advantages such as miniaturization, excellent stability and specificity, the proposed biosensor can be considered as a potential candidate for the rapid analysis of CRP, especially for point-of-care platforms. PMID- 29601594 TI - Proprioception deficits in chronic stroke-Upper extremity function and daily living. AB - BACKGROUND: Proprioception deficits are common post-stroke and predict poor functional outcome. It is unknown if the presence of proprioception deficits is negatively associated with the motor and functional ability of the affected upper extremity and daily living at the chronic stage post-stroke. AIMS: 1) To describe proprioception deficits of individuals with chronic stroke, 2) to correlate the severity of proprioception deficits with the motor and functional ability of the upper extremity, and 3) to compare independence in basic and instrumental activities in daily living (BADL, IADL), upper extremity motor and functional abilities between individuals with and without proprioception deficits. METHODS: 102 adults aged 29-85 years with chronic stroke participated in this cross sectional study. The upper extremity was assessed for proprioception (Thumb localization Test), motor [Fugl-Meyer Motor Assessment (FMA)] and functional ability [Action Research Arm Test (ARAT), Box and Block Test (BBT)], grip strength and daily use [Motor Activity Log (MAL)]. Independence in BADL and IADL was also assessed. RESULTS: 71 participants had intact proprioception, 31 participants had mild-moderate proprioception deficits. Negative significant (p<.001) correlations were found between the severity of proprioception deficits to the motor ability (FMA) (r = -.41), functional ability (ARAT) (r = -.48), dexterity (BBT) (r = -.43), grip strength (r = -.41) and daily-use (MAL amount and quality) (r = -.55 and r = -.54, respectively) of the affected upper extremity. Significant between-group differences were found for BADL, IADL and upper extremity measures. CONCLUSION: Proprioception deficits of individuals with chronic stroke are negatively associated with upper extremity motor and functional abilities and independence in daily living. Therefore, proprioception should be assessed at the chronic stage post-stroke. PMID- 29601595 TI - Effects of dexamethasone on intracochlear inflammation and residual hearing after cochleostomy: A comparison of administration routes. AB - Preservation of residual hearing after cochlear implant is an important issue with regards to hearing performance. Various methods of steroid administration have been widely used in clinical practice to reduce inflammation and preserve residual hearing. Here we compare the effect of different routes of dexamethasone administration on intracochlear inflammation and residual hearing in guinea pig ears. Dexamethasone was delivered into the guinea pigs either through intracochlear, intratympanic or systemic route. The intracochlear concentration of dexamethasone, residual hearing, inflammatory cytokines and histopathologic changes were evaluated over time. A higher intracochlear dexamethasone concentration was observed after intracochlear administration than through the other routes. Residual hearing was better preserved with local dexamethasone administration as was supported by the reduced inflammatory cytokines, more hair cell survival and less severe intracochlear fibrosis and ossification concurrently seen in the local delivery group than in the systemic group. The results demonstrate that local dexamethasone delivery can reduce intracochlear inflammation and preserve residual hearing better than in systemically administered dexamethasone. PMID- 29601596 TI - An anthropometric approach to characterising neonatal morbidity and body composition, using air displacement plethysmography as a criterion method. AB - BACKGROUND: With the greatest burden of infant undernutrition and morbidity in low and middle income countries (LMICs), there is a need for suitable approaches to monitor infants in a simple, low-cost and effective manner. Anthropometry continues to play a major role in characterising growth and nutritional status. METHODS: We developed a range of models to aid in identifying neonates at risk of malnutrition. We first adopted a logistic regression approach to screen for a composite neonatal morbidity, low and high body fat (BF%) infants. We then developed linear regression models for the estimation of neonatal fat mass as an assessment of body composition and nutritional status. RESULTS: We fitted logistic regression models combining up to four anthropometric variables to predict composite morbidity and low and high BF% neonates. The greatest area under receiver-operator characteristic curves (AUC with 95% confidence intervals (CI)) for identifying composite morbidity was 0.740 (0.63, 0.85), resulting from the combination of birthweight, length, chest and mid-thigh circumferences. The AUCs (95% CI) for identifying low and high BF% were 0.827 (0.78, 0.88) and 0.834 (0.79, 0.88), respectively. For identifying composite morbidity, BF% as measured via air displacement plethysmography showed strong predictive ability (AUC 0.786 (0.70, 0.88)), while birthweight percentiles had a lower AUC (0.695 (0.57, 0.82)). Birthweight percentiles could also identify low and high BF% neonates with AUCs of 0.792 (0.74, 0.85) and 0.834 (0.79, 0.88). We applied a sex-specific approach to anthropometric estimation of neonatal fat mass, demonstrating the influence of the testing sample size on the final model performance. CONCLUSIONS: These models display potential for further development and evaluation in LMICs to detect infants in need of further nutritional management, especially where traditional methods of risk management such as birthweight for gestational age percentiles may be variable or non-existent, or unable to detect appropriately grown, low fat newborns. PMID- 29601597 TI - HMGB1/IL-1beta complexes in plasma microvesicles modulate immune responses to burn injury. AB - Modulating immune responses to sepsis and trauma remain one of the most difficult challenges in modern medicine. Large burn injuries (LBI) are a severe form of trauma associated with sepsis, immune impairment, and mortality. Immune dysfunction after LBI is complex, involving both enhanced and impaired immune activation. The release of Damage-Associated Molecular Patterns (DAMPs), such as HMGB1, and cytokines (e.g. IL-1beta) creates an environment of immune dysfunction often leading to end organ failure and death. Both HMGB1 and IL-1beta have been found to play critical roles in sepsis and post-burn immune dysfunction. HMGB1 and IL-1beta have been shown previously to form potent complexes in vitro. We recently identified the presence of HMGB1/IL-1beta heterocomplexes in human tissue. We now find HMGB1/IL-1beta complexes in human and mouse plasma, and identify a synergistic role of HMGB1/IL-1beta complexes in post-burn immune dysfunction. In both humans and mice, we found that HMGB1 was enriched in plasma microvesicles (MVs) after LBI. HMGB1 was found form complexes with IL-1beta. Using flow cytometry of mouse plasma MVs, we identified an increase in an HMGB1+/IL-1beta+ MVs. Using co-IP, HMGB1 was found to bind the pro-form of IL 1beta in mouse and human plasma. Pro-IL-1beta, which is traditionally considered inactive, became active when complexed with HMGB1. Human THP-1 monocytes treated with HMGB1-pro-IL-1beta complexes showed increased transcription of LBI associated cytokines IL-6 and IFNbeta along with suppression of iNOS, mimicking findings associated with LBI. These findings identify that HMGB1/IL-1beta complexes released after burn injuries can modulate immune responses, and microvesicles are identified as a novel reservoir for these immune mediators. These complexes might serve as novel immune targets for the treatment of systemic immune responses due to LBI or other causes of sepsis. PMID- 29601598 TI - Outer membrane vesicles from Neisseria gonorrhoeae target PorB to mitochondria and induce apoptosis. AB - Neisseria gonorrhoeae causes the sexually transmitted disease gonorrhoea by evading innate immunity. Colonizing the mucosa of the reproductive tract depends on the bacterial outer membrane porin, PorB, which is essential for ion and nutrient uptake. PorB is also targeted to host mitochondria and regulates apoptosis pathways to promote infections. How PorB traffics from the outer membrane of N. gonorrhoeae to mitochondria and whether it modulates innate immune cells, such as macrophages, remains unclear. Here, we show that N. gonorrhoeae secretes PorB via outer membrane vesicles (OMVs). Purified OMVs contained primarily outer membrane proteins including oligomeric PorB. The porin was targeted to mitochondria of macrophages after exposure to purified OMVs and wild type N. gonorrhoeae. This was associated with loss of mitochondrial membrane potential, release of cytochrome c, activation of apoptotic caspases and cell death in a time-dependent manner. Consistent with this, OMV-induced macrophage death was prevented with the pan-caspase inhibitor, Q-VD-PH. This shows that N. gonorrhoeae utilizes OMVs to target PorB to mitochondria and to induce apoptosis in macrophages, thus affecting innate immunity. PMID- 29601599 TI - VCAM-1 expression is upregulated by CD34+/CD133+-stem cells derived from septic patients. AB - CD34+/CD133+- cells are a bone marrow derived stem cell population, which presumably contain vascular progenitor cells and are associated with improved vascular repair. In this study, we investigated whether the adhesion molecules ICAM-1 (intercellular adhesion molecule-1), VCAM-1 (vascular adhesion molecule 1), E-selectin und L-selectin, which are involved in homing of vascular stem cells, are upregulated by CD34+/CD133+-stem cells from septic patients and would be associated with improved clinical outcome. Peripheral blood mononuclear cells from intensive care unit (ICU) patients with (n = 30) and without sepsis (n = 10), and healthy volunteers (n = 15) were isolated using Ficoll density gradient centrifugation. The expression of VCAM-1, ICAM-1, E-selectin and L-selectin was detected on CD34+/CD133+-stem cells by flow cytometry. The severity of disease was assessed by the Simplified Acute Physiology Score (SAPS) II. Serum concentrations of vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-2 were determined by Enzyme-linked immunosorbent assay. The expression of VCAM-1, ICAM-1, E-selectin and L-selectin by CD34+/CD133+-stem cells was significantly upregulated in septic patients, and correlated with sepsis severity. Furthermore, high expression of VCAM-1 by CD34+/CD133+-stem cells revealed a positive association with mortalitiy (p<0.05). Furthermore, significantly higher serum concentrations of VEGF and Ang-2 were found in septic patients, however none showed a strong association with survival. Our data suggest, that VCAM-1 upregulation on CD34+/CD133+-stem cells could play a crucial role in their homing in the course of sepsis. An increase in sepsis severity resulted in both and increase in CD34+/CD133+-stem cells and VCAM-1-expression by those cells, which might reflect an increase in need for vascular repair. PMID- 29601600 TI - The incidence of medically-attended norovirus gastro-enteritis in Japan: Modelling using a medical care insurance claims database. AB - BACKGROUND: The burden of medically-attended acute gastro-enteritis (MA-AGE) that can be attributed to norovirus is not well established in Japan. Using a nationwide database of medical care insurance claims, we estimated the incidence of medically-attended norovirus-attributable gastroenteritis (MA-NGE) in Japan. METHODS: The incidences of MA-NGE outpatient consultations or hospitalization in Japan were modelled on seasonal patterns of MA-AGE for unspecified causes derived from the Japan Medical Data Center (JMDC) database for the period July 2007 to June 2015. RESULTS: Mean age-adjusted annual incidence rates (per 10,000 person years) of MA-NGE associated with outpatient care or hospitalization were 389 (95% CI 269-558) and 13 (95% CI 9-20), respectively. Highest rates were in children under 5 years of age: 1,569 (95% CI 1,325-1,792) for outpatient consultations and 48 (95% CI 39-56) for hospitalizations. Of all gastroenteritis episodes associated with outpatient care or hospitalization, 29% and 31% were attributed to norovirus, respectively. Norovirus was estimated to be responsible for 4,964,000 outpatient visits (95% CI 3,435,000-7,123,000) and 171,000 hospitalizations (95% CI 110,000-251,000) per year across Japan. CONCLUSIONS: Incidence rates of MA-AGE are high in Japan, and norovirus-attributable disease is at least as high as in some other developed countries. PMID- 29601602 TI - Risk of ischemic stroke in metabolically healthy obesity: A nationwide population based study. AB - BACKGROUND: Whether metabolically healthy obese (MHO) individuals are at increased risk of ischemic stroke is not well known. We investigated the association of the MHO phenotype with ischemic stroke. METHODS: A total of 354,083 adults (age 45.8 +/- 14.2 years) from the Korean National Health Insurance Service-National Sample Cohort enrolled in 2004-2008 were followed-up for incident ischemic stroke until 2013. Subjects meeting none of the metabolic syndrome criteria were classified as 'metabolically healthy'. The cohort was categorized into four groups according to obesity and metabolic status: metabolically healthy normal weight (MHNW), metabolically unhealthy normal weight (MUNW), MHO, and metabolically unhealthy obese (MUO). RESULTS: Ischemic stroke was newly diagnosed in 4,884 (1.4%) individuals during a mean follow-up of 7.4 +/ 1.5 years. Stroke incidence rates for the MHNW, MUNW, MHO, and MUO groups were 0.56, 2.61, 0.61, and 2.76 per 1,000 person-years, respectively. While risk for stroke increased significantly in metabolically unhealthy groups, it was not increased in MHO compared to the MHNW group on multivariate analysis. In metabolically healthy individuals, obesity did not increase the risk for ischemic stroke, regardless of the severity of obesity. Meanwhile, in metabolically unhealthy individuals, being obese was significantly associated with increased risk of stroke. CONCLUSIONS: MHO individuals were not at increased risk for ischemic stroke. However, obesity increased risk for ischemic stroke in persons with metabolic risk factors; therefore, maintaining normal weight may be more important for this population. Also, metabolic unhealthiness showed greater association than obesity with stroke. PMID- 29601601 TI - Prenylated phloroglucinols from Hypericum scruglii, an endemic species of Sardinia (Italy), as new dual HIV-1 inhibitors effective on HIV-1 replication. AB - In a search for new potential multitarget anti-HIV compounds from natural products, we have identified in Hypericum scruglii, an endemic and exclusive species of Sardinia (Italy), a potent plant lead. The phytochemical study of the hydroalcoholic extract obtained from its leaves led to the isolation of its most abundant secondary metabolites, belonging to different chemical classes. In particular, three phloroglucinols derivatives were identified, confirming their significance as chemotaxonomic markers of the Hypericum genus. Among them, the 3 (13-hydroxygeranyl)-1-(2'-methylbutanoyl)phloroglucinol was reported here for the first time. All six isolated compounds have been evaluated firstly for the inhibition of both Human Immunodeficiency Virus type 1 (HIV-1) Reverse Transcriptase (RT)-associated DNA Polymerase (RDDP) and Ribonuclease H (RNase H) activities, for the inhibition of HIV-1 integrase (IN) in biochemical assays, and also for their effect on viral replication. Among the isolated metabolites, three phloroglucinol derivatives and quercitrin were effective on both RT-associated RDDP and RNase H activities in biochemical assays. The same active compounds affected also HIV-1 IN strand transfer function, suggesting the involvement of the RNase H active site. Furthermore, phloroglucinols compounds, included the newly identified compound, were able to inhibit the HIV-1 replication in cell based assays. PMID- 29601603 TI - The bacterial type III-secreted protein AvrRps4 is a bipartite effector. AB - Bacterial effector proteins secreted into host plant cells manipulate those cells to the benefit of the pathogen, but effector-triggered immunity (ETI) occurs when effectors are recognized by host resistance proteins. The RPS4/RRS1 pair recognizes the Pseudomonas syringae pv. pisi effector AvrRps4. AvrRps4 is processed in planta into AvrRps4N (133 amino acids), homologous to the N-termini of other effectors including the native P. syringae pv. tomato strain DC3000 effector HopK1, and AvrRps4C (88 amino acids). Previous data suggested that AvrRps4C alone is necessary and sufficient for resistance when overexpressed in heterologous systems. We show that delivering AvrRps4C from DC3000, but not from a DC3000 hopK1- strain, triggers resistance in the Arabidopsis accession Col-0. Delivering AvrRps4C in tandem with AvrRps4N, or as a chimera with HopK1N, fully complements AvrRps4-triggered immunity. AvrRps4N in the absence of AvrRps4C enhances virulence in Col-0. In addition, AvrRps4N triggers a hypersensitive response in lettuce that is attenuated by coexpression of AvrRps4C, further supporting the role of AvrRps4N as a bona fide effector domain. Based on these results we propose that evolutionarily, fusion of AvrRps4C to AvrRps4N may have counteracted recognition of AvrRps4N, and that the plant RPS4/RRS1 resistance gene pair was selected as a countermeasure. We conclude that AvrRps4 represents an unusual chimeric effector, with recognition in Arabidopsis by RPS4/RRS1 requiring the presence of both processed effector moieties. PMID- 29601604 TI - An automated quantitative analysis of cell, nucleus and focal adhesion morphology. AB - Adherent cells sense the physical properties of their environment via focal adhesions. Improved understanding of how cells sense and response to their physical surroundings is aided by quantitative evaluation of focal adhesion size, number, orientation, and distribution in conjunction with the morphology of single cells and the corresponding nuclei. We developed a fast, user-friendly and automated image analysis algorithm capable of capturing and characterizing these individual components with a high level of accuracy. We demonstrate the robustness and applicability of the algorithm by quantifying morphological changes in response to a variety of environmental changes as well as manipulations of cellular components of mechanotransductions. Finally, as a proof of-concept we use our algorithm to quantify the effect of Rho-associated kinase inhibitor Y-27632 on focal adhesion maturation. We show that a decrease in cell contractility leads to a decrease in focal adhesion size and aspect ratio. PMID- 29601605 TI - Increased carriage of non-vaccine serotypes with low invasive disease potential four years after switching to the 10-valent pneumococcal conjugate vaccine in The Netherlands. AB - The 7-valent pneumococcal conjugate vaccine (PCV7) was introduced in The Netherlands in 2006 and was replaced by PHiD-CV10 in 2011. Data on carriage prevalence of S. pneumoniae serotypes in children and invasive pneumococcal disease (IPD) in children and older adults were collected to examine the impact of PCVs on carriage and IPD in The Netherlands. Pneumococcal carriage prevalence was determined by conventional culture of nasopharyngeal swabs in 24-month-old children in 2015/2016. Data were compared to similar carriage studies in 2005 (pre-PCV7 introduction), 2009, 2010/2011 and 2012/2013. Invasive pneumococcal disease isolates from hospitalized children <5 years and adults >65 years (2004 2016) were obtained by sentinel surveillance. All isolates were serotyped by Quellung. Serotype invasive disease potential was calculated using carriage and nationwide IPD data in children. The overall pneumococcal carriage rate was 48% in 2015/2016, lower than in 2010/2011 (64%) and pre-vaccination in 2005 (66%). Carriage of the previously dominant non-vaccine serotypes 19A and 11A has declined since 2010/2011, from 14.2% to 4.6% and 4.2% to 2.7%, respectively, whereas carriage of serotypes 6C and 23B has increased (4.2% to 6.7% and 3.9% to 7.3%), making serotypes 6C and 23B the most prevalent carriage serotypes. IPD incidence declined in children (20/100,000 cases in 2004/2006 to 6/100,000 cases in 2015/2016) as well as in older adults (63/100,000 cases to 51/100,000 cases). Serotypes 6C, 23B and 11A have high carriage prevalence in children, but show low invasive disease potential. Serotype 8 is the main causative agent for IPD in older adults (11.3%). In conclusion, 10 years after the introduction of pneumococcal vaccination in children in The Netherlands shifts in carriage and disease serotypes are still ongoing. Surveillance of both carriage and IPD is important to assess PCV impact and to predict necessary future vaccination strategies in both children and older adults. PMID- 29601606 TI - Chronic noise-exposure exacerbates insulin resistance and promotes the manifestations of the type 2 diabetes in a high-fat diet mouse model. AB - Epidemiological studies have revealed that noise exposure was associated with an increased risk of type 2 diabetes mellitus (T2DM). However, the exact nature of that association remains to be elucidated. The present study is designed to examine the effects of chronic noise exposure on the development of T2DM in combination with a high-fat-diet (HFD) in mice. Here we show that chronic noise exposure at 85 dB SPL (4 h /day, below the safety limit for occupational noise exposure) exaggerated multiple metabolic abnormalities induced by HFD in C57BL/6J male mice, including worsened glucose intolerance, insulin resistance, fasting hyperglycemia and dyslipidemia. Furthermore, noise exposure exhibited a paradoxical impact on fat accumulation and circulating levels of free fatty acid, indicating a potential stimulating effect of noise on lipolysis. These results provide first in vivo supporting evidence for the causative role of noise exposure in diabetogenesis and pinpoint a noise-associated increase in blood free fatty acid levels as a possible mediator accelerating the effect of noise on the development of insulin resistance and T2DM. PMID- 29601607 TI - Internalization of subcellular-scale microfabricated chips by healthy and cancer cells. AB - Continuous monitoring of physiological parameters inside a living cell will lead to major advances in our understanding of biology and complex diseases, such as cancer. It also enables the development of new medical diagnostics and therapeutics. Progress in nanofabrication and wireless communication has opened up the potential of making a wireless chip small enough that it can be wholly inserted into a living cell. To investigate how such chips could be internalized into various types of living single cells and how this process might affect cells' physiology, we designed and fabricated a series of multilayered micron scale tag structures with different sizes as potential RFID (Radio Frequency IDentification) cell trackers. While the present structures are test structures that do not resonate, the tags that do resonate have similar structure from device fabrication, material properties, and device size point of view. The structures are in four different sizes, the largest with the lateral dimension of 9 MUm * 21 MUm. The thickness for these structures is kept constant at 1.5 MUm. We demonstrate successful delivery of our fabricated chips into various types of living cells, such as melanoma skin cancer, breast cancer, colon cancer and healthy/normal fibroblast skin cells. To our surprise, we observed a remarkable internalization rate difference between each cell type; the uptake rate was faster for more aggressive cancer cells than the normal/healthy cells. Cell viability before and after tag cellular internalization and persistence of the internalized tags have also been recorded over the course of five days of incubation. These results establish the foundations of the possibility of long term, wireless, intracellular physiological signal monitoring. PMID- 29601608 TI - In vitro co-cultures of human gut bacterial species as predicted from co occurrence network analysis. AB - Network analysis of large metagenomic datasets generated by current sequencing technologies can reveal significant co-occurrence patterns between microbial species of a biological community. These patterns can be analyzed in terms of pairwise combinations between all species comprising a community. Here, we construct a co-occurrence network for abundant microbial species encompassing the three dominant phyla found in human gut. This was followed by an in vitro evaluation of the predicted microbe-microbe co-occurrences, where we chose species pairs Bifidobacterium adolescentis and Bacteroides thetaiotaomicron, as well as Faecalibacterium prausnitzii and Roseburia inulinivorans as model organisms for our study. We then delineate the outcome of the co-cultures when equal distributions of resources were provided. The growth behavior of the co culture was found to be dependent on the types of microbial species present, their specific metabolic activities, and resulting changes in the culture environment. Through this reductionist approach and using novel in vitro combinations of microbial species under anaerobic conditions, the results of this work will aid in the understanding and design of synthetic community formulations. PMID- 29601609 TI - Withstanding austerity: Equity in health services utilisation in the first stage of the economic recession in Southern Spain. AB - Scant research is available on the impact of the current economic crisis and austerity policies on inequality in health services utilisation in Europe. This study aimed to describe the trends in horizontal inequity in the use of health services in Andalusia, Spain, during the early years of the Great Recession, and the contribution of demographic, economic and social factors. Consultation with a general practitioner (GP) and specialist, hospitalisation and emergency care were studied through the Andalusian Health Survey 2007 (pre-crisis) and 2011-2012 (crisis), using a composite income index as socioeconomic status (SES) indicator. Horizontal inequity indices (HII) were calculated to take differential healthcare needs into account, and a decomposition analysis of change in inequality between periods was performed. Results showed that before the crisis, the HII was positive (greater access for people with higher SES) for specialist visits but negative (greater access for people with lower SES) in the other three utilisation models. During the crisis no change was observed in inequalities in GP visits, but a pro-poor development was seen for the other types of utilisation, with hospital and emergency care showing significant inequality in favour of low income groups. Overall, the main contributors to pro-poor changes in utilisation were socio-economic variables and poor mental health, due to changes in their elasticities. Our findings show that inequalities in healthcare utilisation largely remained in favour of the less well-off, despite the cuts in welfare benefits and health services provision during the early years of the recession in Andalusia. Further research is needed to monitor the potential impact of such measures in subsequent years. PMID- 29601610 TI - Preventive behaviors adults report using to avoid catching or spreading influenza, United States, 2015-16 influenza season. AB - INTRODUCTION: Influenza vaccination can prevent influenza and potentially serious influenza-related complications. Although the single best way to prevent influenza is annual vaccination, everyday preventive actions, including good hygiene, health, dietary, and social habits, might help, too. Several preventive measures are recommended, including: avoiding close contact with people who are sick; staying home when sick; covering your mouth and nose when coughing or sneezing; washing your hands often; avoiding touching your eyes, nose, and mouth; and practicing other good health habits like cleaning and disinfecting frequently touched surfaces, getting plenty of sleep, and drinking plenty of fluids. Understanding public acceptance and current usage of these preventive behaviors can be useful for planning both seasonal and pandemic influenza prevention campaigns. This study estimated the percentage of adults in the United States who reported practicing preventive behaviors to avoid catching or spreading influenza, and explored associations of reported behaviors with sociodemographic factors. METHODS: We analyzed data from 2015 National Internet Flu Survey, a nationally representative probability-based Internet panel survey of the non institutionalized U.S. population >=18 years. The self-reported behaviors used to avoid catching or spreading influenza were grouped into four and three non mutually exclusive subgroups, respectively. Weighted proportions were calculated. Multivariable logistic regression models were used to calculate adjusted prevalence differences and to determine independent associations between sociodemographic characteristics and preventive behavior subgroups. RESULTS: Common preventive behaviors reported were: 83.2% wash hands often, 80.0% cover coughs and sneezes, 78.2% stay home if sick with a respiratory illness, 64.4% avoid people sick with a respiratory illness, 51.7% use hand sanitizers, 50.2% get treatment as soon as possible, and 49.8% report getting the influenza vaccination. Race/ethnicity, gender, age, education, income, region, receipt of influenza vaccination, and household size were associated with use of preventive behaviors after controlling for other factors. CONCLUSION: Many adults in the United States reported using preventive behaviors to avoid catching or spreading influenza. Though vaccination is the most important tool available to prevent influenza, the addition of preventive behaviors might play an effective role in reducing or slowing transmission of influenza and complement prevention efforts.

AB - [This corrects the article DOI: 10.1093/pch/pxx123.][This corrects the article DOI: 10.1093/pch/pxx123.]. PMID- 29601611 TI - Next generation clinical guidance for primary care in South Africa - credible, consistent and pragmatic. AB - BACKGROUND: Agreed international development standards underpin high quality de novo clinical practice guidelines (CPGs). There is however, no international consensus on how high quality CPGs should 'look'; or on whether high quality CPGs from one country can be viably implemented elsewhere. Writing de novo CPGs is generally resource-intensive and expensive, making this challenging in resource poor environments. This paper proposes an alternative, efficient method of producing high quality CPGs in such circumstances, using existing CPGs layered by local knowledge, contexts and products. METHODS: We undertook a mixed methods case study in South African (SA) primary healthcare (PHC), building on findings from four independent studies. These comprised an overview of international CPG activities; a rapid literature review on international CPG development practices; critical appraisal of 16 purposively-sampled SA PHC CPGs; and additional interrogation of these CPGs regarding how, why and for whom, they had been produced, and how they 'looked'. RESULTS: Despite a common aim to improve SA PHC healthcare practices, the included CPGs had different, unclear and inconsistent production processes, terminology and evidence presentation styles. None aligned with international quality standards. However many included innovative succinct guidance for end-users (which we classified as evidence-based summary recommendations, patient management tools or protocols). We developed a three tiered model, a checklist and a glossary of common terms, for more efficient future production of better quality, contextually-relevant, locally-implementable SA PHC CPGs. Tier 1 involves transparent synthesis of existing high quality CPG recommendations; Tier 2 reflects local expertise to layer Tier 1 evidence with local contexts; and Tier 3 comprises tailored locally-relevant end-user guidance. CONCLUSION: Our model could be relevant for any resource-poor environment. It should reduce effort and costs in finding and synthesising available research evidence, whilst efficiently focusing scant resources on contextually-relevant evidence-based guidance, and implementation. PMID- 29601613 TI - An Acne Survey from the World's Largest Annual Gathering of Twins. AB - IMPORTANCE: Surveying identical twins allows us to qualitatively separate genetic and environmental factors that may contribute to acne severity. OBJECTIVE: To study a cohort of identical and fraternal twins to identify environmental factors that may influence acne severity. DESIGN, SETTING, PARTICIPANTS: A survey was administered to 139 identical and fraternal twin multiples (279 subjects) at the Annual Twins Day Festival in Twinsburg, Ohio on August 6-7, 2016. One set of triplets was included. MAIN OUTCOME(S) AND MEASURE(S): Acne incidence, severity, and triggers were analyzed using the N-1 Chi-squared test and paired, 2-tailed t test. RESULTS: The proportion of concordant pairs was significantly higher in identical (64%) vs fraternal (49%) twins (P=0.04). Acne was found to be associated with polycystic ovarian syndrome (PCOS; P=0.045), anxiety (P =0.014), and asthma (P=0.026). Identical twin pairs with acne had a higher BMI (P= 0.020) and exercised significantly less (P=0.001) than those without acne. Analyzing concordant twin pairs, the twin with more severe acne was more likely to report aggravation of acne with cosmetic product use (P=0.002) and sugar intake (P=0.048). CONCLUSIONS AND REVELANCE: This twin study further supports that there may be a genetic phenotypic link, though social and environmental factors may also have an influence in the disease process.

. PMID- 29601614 TI - Dihydroxyacetone: A Review. AB - The sunless tanning industry has experienced rapid growth due to public education on the dangers of ultraviolet radiation on skin and improvements in products. Dihydroxyacetone (DHA) is a 3-carbon sugar allowed by the Food and Drug Administration (FDA) as a color additive in sunless tanning products. Bronzers, a product removed with soap and water, may also contain DHA. We aim to review the literature on DHA. DHA is intended for external application, not including the mucous membranes or in or around the eye area. DHA has been used in spray-tan booths and by airbrushing it onto consumers, although these are unapproved uses, as contact with the color additive is not restricted to the external part of the body. Consequently, the FDA recommends customers shield their eyes, lips, and mucous membranes, as well as refrain from ingestion or inhalation of DHA. Unlike sunscreens, products that protect against ultraviolet radiation and are regulated by the FDA as non-prescription drugs, sunless tanning products are regulated as cosmetics and cannot provide any protection from exposure to ultraviolet radiation. There are reports of non-cosmetic uses of DHA that are not FDA approved. With the wide-spread use of DHA, additional studies on its safety are warranted.

. PMID- 29601615 TI - Understanding Patient Experience With Hyperhidrosis: A National Survey of 1,985 Patients. AB - Hyperhidrosis affects 4.8% of the US population, and despite the well documented negative impact of hyperhidrosis on patients' lives, data are generally lacking on the patient experience with this condition. The International Hyperhidrosis Society (IHHS) conducted a study in 2014, and initial results confirmed the multifaceted impact of hyperhidrosis on quality of life and underscored the need for disease awareness and effective management. To provide further insight into the hyperhidrosis patient experience, additional results focusing on family history, physician interaction, impact on daily activities, and treatment satisfaction are presented here. The online survey included 22 multiple-choice questions (some allowing multiple responses). Respondents were IHHS newsletter registrants in the US self-identified as suffering with excessive sweating (ie, answering 'yes' to Question 1). Of 28,587 survey invitations, a total of 5,042 recipients (17.6%) opened the e-mail, and 2,045 respondents provided an answer to Question 1. Of these, 1,985 (6.9%) self-identified as having excessive sweating and continued the survey. Over 18% of survey respondents reported an immediate family member with excessive sweating. The top three areas impacted by excessive sweating were daily activity, clothing choice, and work/career (average rank scores over 3.0 for each area; range 1-8 with lower scores indicating greater impact). Nearly half (48.9%) of respondents reported waiting 10 or more years prior to seeking medical help, and 85.0% waited at least 3 years. Of the 87.2% of respondents who received treatment for hyperhidrosis, patients were most satisfied with injections and least satisfied with prescription and over-the counter antiperspirants and liposuction. These survey results add important clinical insight for the underserved hyperhidrosis patient population. The reported delay in seeking proper medical attention highlights the need to increase hyperhidrosis awareness among the public and clinicians, to reduce stigma associated with the condition, and to encourage active treatment strategies.

. PMID- 29601616 TI - Frontal Fibrosing Alopecia and Concomitant Lichen Planus Pigmentosus: A Case Series of Seven African American Women. AB - The association of frontal fibrosing alopecia (FFA) and lichen planus pigmentosus (LPPigm) is rare. Prior reports suggest that FFA and LPPigm are on the same spectrum of disease, and a diagnosis of LPPigm may predict the future development of FFA. We aim to further characterize the association between FFA and LPPigm by reviewing the clinical cases of seven African American women. Seven patients with FFA were diagnosed clinically by recession of frontotemporal hairline and confirmed by histopathologic examination showing lymphocyte-mediated cicatricial alopecia. LPPigm was diagnosed by clinical evaluation alone based on the characteristic morphology, color, and distribution of the lesions. It is difficult to distinguish whether halted progression of FFA was due to the success of the treatment regimen or spontaneous stabilization of disease over time. Our case series supports the theory that FFA and LPPigm likely exist on the same spectrum of disease. Our observations demonstrate a likely positive correlation between FFA and LPPigm.

. PMID- 29601617 TI - Collagen Powder in Wound Healing. AB - Chronic wounds, such as pressure ulcers, diabetic foot ulcers, and venous leg ulcers, are associated with high costs, poor quality of life, and significant morbidity and mortality. A chronic wound develops when progression through the normal phases of wound healing goes awry, creating a hostile environment with elevated levels of pro-inflammatory cytokines, increased matrix metalloproteinases (MMPs), destruction of extracellular matrix (ECM) components, and diminished activity of growth factors and other soluble mediators. The advent of advanced wound care therapies allows for a targeted approach to the treatment of nonhealing wounds by addressing specific molecular defects in healing. Collagen is an essential building block of the skin that when utilized as an adjunctive wound therapy stimulates and recruits immune cells and fibroblasts and martyrs itself for degradation by MMPs, thereby preserving native ECM structure and promoting healing. Particulate or powdered collagen is processed to minimize covalent cross-linking and is purported to exert its biologic activity immediately upon application. This article critically reviews the current evidence for collagen powder as an adjunctive therapy for chronic wounds and presents indications, limitations, and principles of use. In general, there is a need for high quality studies and randomized control trials to support its use in clinical practice.

AB - INTRODUCTION: A variety of topical anesthetic creams are available to reduce pain associated with dermatological procedures. Pliaglis is a self-occluding eutectic mixture of lidocaine and tetracaine. STUDY OBJECTIVES: To evaluate the post marketing safety profile of Pliaglis and efficacy in terms of pain reduction, product satisfaction, and daily practice use prior to pre-defined dermatological procedures. METHODS: A prospective, non-interventional study conducted at 44 sites in four European countries; 581 patients were treated prior to dermatological procedures such as pulsed-dye laser therapy, laser-assisted hair removal, non-ablative laser resurfacing, dermal filler injections, and vascular access. Efficacy was assessed by patients and investigators and included pain intensity (visual analogue scale [VAS]), satisfaction, and adequacy of pain relief. Safety was evaluated by adverse event (AE) reporting. RESULTS: In 75% of the performed procedures, patients scored the pain experienced during the procedure as <=30 mm on the VAS and most were very satisfied or satisfied with the pain reduction. The investigators assessed the product as providing adequate anesthesia in 97% of the performed procedures and were mostly very satisfied or satisfied with the convenience of use (79%) and tolerability (95%). Twenty-four AEs were reported in 18 (3%) patients. DISCUSSION: Most patients experienced mild pain only as evident by the <= 30 mm VAS scores. Patients and investigators were aligned with regards to both product satisfaction and their opinion on adequacy of pain reduction. The AE frequency was low compared to previous studies, possibly relating to different ways of collecting AEs. CONCLUSION: Pliaglis was well-tolerated and provided adequate pain reduction prior to dermatological procedures. www.clinicaltrials.gov (NCT01800474).

. PMID- 29601619 TI - Topical Agents for Scar Management: Are They Effective? AB - Scar formation is the body's natural healing response to reestablish dermal integrity following an injury. Excessive scarring, however, can cause significant cosmetic, functional, and psychological problems. A wide variety of topical creams, lotions, and oils are available for scar treatment or wound healing. Sieving through the options and selecting the best option for their patients can be challenging for clinicians, especially given that clinical evidence for many of the active agents in commonly used topical treatments is lacking. The goal of this review is to provide an overview of topical treatments utilized for scar management, including their mechanism of action and evidence of efficacy. As knowledge of the wound healing process is critical to understanding the effects of topical treatments, the pathophysiology of wound healing is also reviewed.

. PMID- 29601620 TI - Multi-Center, Double-Blind, Vehicle-Controlled Clinical Trial of an Alpha and Beta Defensin-Containing Anti-Aging Skin Care Regimen With Clinical, Histopathologic, Immunohistochemical, Photographic, and Ultrasound Evaluation. AB - BACKGROUND/OBJECTIVES: Anti-aging strategies utilizing stem cells are in the forefront. Alpha and beta defensins are natural immune peptides that have been shown to activate an LGR6-positive stem cell locus in the hair follicle, identified as the source of most new epidermal cells during acute wound healing. We investigated the ability of biomimetic alpha and beta defensin molecules, supplemented with supportive cosmetic ingredients, formulated into three skin care products, at improving the structure and function of aging skin. METHODS: A participant- and investigator -blinded, placebo-controlled, multi-center trial was performed in outpatient settings. Forty-four healthy female subjects, aged 41 71 years, skin types I-V, completed the study with 2/3 receiving full formula and 1/3 receiving the placebo formula. A skin care regimen of 3 products (serum, cream, and mask) containing alpha-defensin 5 and beta-defensin 3, and other cosmetic ingredients, was applied to the face, post-auricular, and neck skin two times per day for 12 weeks in those receiving full formula, whereas the placebo group received the identically packaged regimen without the active ingredients. Methods of evaluation included histopathology and immunohistochemistry (7 subjects), clinical evaluation of pores, superficial and deep wrinkles based on Griffiths scale, and high-resolution photography (all subjects). In addition, a subset of 15 patients were evaluated with the QuantifiCare system (3-dimensional imaging and skin care scores for evenness, pores, oiliness) and Cortex measurements (high-resolution skin ultrasound, TEWL, elasticity, color, and hydration). Data points for evaluation included baseline, 6 weeks, and 12 weeks. All patients used the same sunscreen and cleanser, which was provided to them. RESULTS: The full formula regimen caused a significantly (P equals 0.027) increased thickness of the epidermis as seen in histology, not seen in the placebo group, with no signs of inflammation. No excessive cell proliferation was detected in either group as measured by Ki67-immunohistochemistry. Reduction in visible pores, superficial wrinkles, oiliness, pigmentation, and improvement of skin evenness, were statistically significant. A trend for improvement was also observed in skin elasticity, TEWL, and hydration; these did not achieve statistical significance. Ultrasound and histopathology demonstrated increases in dermal thickness in individual patients, without statistical significance. Comprehensive improvement in all 5 parameters, including visible pores, hyperpigmentation, superficial and deep wrinkles, and epidermal thickness, was statistically significant when the subset of participants assigned for histology in full formula group was compared with the placebo group participants. CONCLUSIONS: A 3-product skin care regimen containing alpha and beta defensins globally improves the visual appearance and structure of aging skin without irritation, dryness, or inflammation. Specifically, this regimen increases epidermal thickness, reduces appearance of pores, reduces wrinkles, and reduces melanin. This skin care regimen stimulates rejuvenation without evidence of increase of a marker of carcinogenic stimulation. This data is consistent with the hypothesis that a defensin-containing skin care regimen activates the body's own dormant stem cells to generate healthy new epidermal cells.

PMID- 29601621 TI - Prospective, Randomized, Investigator-Blinded, Split-Face Evaluation of a Topical Crosslinked Hyaluronic Acid Serum for Post-Procedural Improvement of Skin Quality and Biomechanical Attributes. AB - BACKGROUND: This split-face, controlled study investigated the ability of a topical crosslinked hyaluronic acid formulation (RHA serum) to enhance clinical results from fillers, microneedling, or chemical peeling of aging skin. Previous comparative skin explant studies demonstrated greater efficacy of RHA serum than topical non-crosslinked high or low molecular weight hyaluronic acid in decreasing trans-epidermal water loss, increasing epidermal hydration, and improving corneocyte microstructure. METHODS: 24 female subjects aged 35 to 55 were enrolled. 8 received intradermal hyaluronic acid filler injection, 8 received microneedling, and 8 received superficial mandelic acid chemical peeling. Subjects initiated twice-daily, standardized application of RHA serum to one side of the face 2 days after the procedure. Topographical imaging, bioinstrumental, and blinded clinical evaluations were performed at days 0, 14, and 28. RESULTS: Areas treated with RHA serum showed statistically significant improvements in skin surface topography and hydration compared to untreated areas. Blinded investigator scoring showed greater improvement of RHA serum treated skin in moisture, tone/complexion, radiance, texture, uniformity, and global appearance. Subjects' questionnaire responses correlated with these findings. Subjects expressed greater satisfaction with appearance of the treated hemiface. No adverse events were observed during the study. CONCLUSIONS: When initiated post-procedurally, topical RHA serum was well-tolerated and enhanced biomechanical properties, quality, and clinical appearance of the skin. Based on these data, RHA serum may be of value in improving patient outcomes and satisfaction following minimally invasive aesthetic procedures. The availability of the same hyaluronic acid technology also as a cohesive, tissue-integrating injectable filler enables synergistic, multi-level treatment plans to be devised.

. PMID- 29601622 TI - A Systematic Review of Topical Finasteride in the Treatment of Androgenetic Alopecia in Men and Women. AB - INTRODUCTION: Currently, only topical minoxidil (MNX) and oral finasteride (FNS) are approved by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of androgenetic alopecia. Although FNS is efficacious for hair regrowth, its systemic use is associated with side effects limiting long-term utilization. Exploring topical FNS as an alternative treatment regimen may prove promising. METHODS: A search was conducted to identify studies regarding human in vivo topical FNS treatment efficacy including clinically relevant case reports, randomized controlled trials (RCTs), and prospective studies. RESULTS: Seven articles were included in this systematic review. In all studies, there was significant decrease in the rate of hair loss, increase in total and terminal hair counts, and positive hair growth assessment with topical FNS. Both scalp and plasma DHT significantly decreased with application of topical FNS; no changes in serum testosterone were noted. CONCLUSION: Preliminary results on the use of topical FNS are limited, but safe and promising. Continued research into drug-delivery, ideal topical concentration and application frequency, side effects, and use for other alopecias will help to elucidate the full extent of topical FNS' use.

AB - The bony structures of the face provide the framework upon which the soft-tissue envelope rests, such that facial symmetry and proportionality usually depend upon the morphological patterns and anthropometrical measurements of a symmetrical skull. Facial bony pillars are dynamic and variable according to the demands placed upon them, as well as gender and aging differences. Thus, a more profound knowledge of facial supporting pillars and their dynamic behavior by physicians who practice minimally cosmetic procedures would allow for a more natural approach to facial beautification. It would help them to rebalance age-related and asymmetric congenital imperfections, and minimize any harmful stigma associated with bad cosmetic practice.

On clinical examination, the patient had well-demarcated, pink, atrophic plaques and superficial erosions over the inframammary folds and mid-chest. She also had well-demarcated, hyperpigmented, hyperkeratotic scaly plaques over the abdomen, suprapubic region, elbows, knees, and back with sporadic small superficial blisters. A punch biopsy of the right abdomen was performed and revealed psoriasiform epidermal hyperplasia, focal parakeratosis, and acantholysis throughout the superficial spinous and granular layers. Only a sparse inflammatory infiltrate was present in the underlying dermis. Clinical and histological findings supported the diagnosis of pemphigus foliaceus (PF), but psoriasis was included in the differential diagnosis due to the presence of discrete plaques with an erythematous border. We hypothesize that patients with psoriasiform presentations of PF may be misdiagnosed with plaque psoriasis. It is important to distinguish between PF and psoriasis as there is evidence that ultraviolet light, a common treatment for psoriasis, may exacerbate PF. We document and highlight this atypical psoriasiform presentation of PF in a patient with skin of color to raise awareness and improve diagnosis and outcomes.

AB - Proximal subungual onychomycosis (PSO), which predominantly involves the nail plate from the proximal nail fold, is the rarest form of onychomycosis. Classically associated with an immunocompromised state, PSO is an uncommon diagnosis in individuals without immunodeficiency. We present a case of a healthy 51-year-old man, who presented with a three-month history of white discoloration of multiple toenails. Physical examination revealed white, opaque patches on the proximal third nail plates of multiple toenails. The affected digits also demonstrated proximal onycholysis, subungual debris, and mild paronychia. Laboratory examinations, including routine serologic studies as well as human immunodeficiency virus and antinuclear antibodies, were within normal limits. Proximal nail fragments of the left hallux showed sections of dystrophic nail plate with mounds of parakeratosis, collections of neutrophils, and hyphae that highlighted with periodic acid-Schiff staining. The patient was diagnosed with PSO and tinea pedis bilaterally and treated with oral fluconazole with gradual improvement. This case of PSO highlights the potential for its rare occurrence in a healthy host. However, the clinical presentation of PSO should trigger an evaluation for possible immunodeficiency.

AB - Although high accuracy rates have been achieved for adult skeletal sex estimation, it is unclear at what age sexually dimorphic traits of the skull become fully developed and useful in subadults. Four linear distances that capture sexual dimorphism-the nuchal crest, mastoid process, glabella, and mental eminence-were measured in a longitudinal sample of lateral cranial radiographs from 10 males and 10 females in the Denver Growth Study (total n = 190). The age full trait expression was attained was compared to that of dental maturity (i.e., third molar eruption). The mental eminence reached full expression significantly earlier than dental maturity (p < 0.001), although a high degree of variability was observed. Ages of expression of the other traits did not differ significantly from dental maturity. These results suggest that in forensic cases, where misclassification can have substantial impacts, cranial traits cannot yet be used reliably for sex estimation prior to third molar eruption.

AB - Although considerable evidence has accumulated on the defensive activity of plant volatile organic compounds against pathogens and insect herbivores, less is known about the significance of volatile organic compounds emitted by plants under abiotic stress. Here, we report that green leaf volatiles (GLVs), which were previously shown to prime plant defences against insect herbivore attack, also protect plants against cold stress (4 degrees C). We show that the expression levels of several cold stress-related genes are significantly up-regulated in maize (Zea mays) seedlings treated with physiological concentrations of the GLV, (Z)-3-hexen-1-yl acetate (Z-3-HAC), and that seedlings primed with Z-3-HAC exhibit increased growth and reduced damage after cold stress relative to unprimed seedlings. Together, these data demonstrate the protective and priming effect of GLVs against cold stress and suggest an activity of GLVs beyond the activation of typical plant defence responses against herbivores and pathogens. PMID- 29601633 TI - Programmed death-ligand 1 (PD-L1) expression in pleomorphic carcinoma of the lung. AB - BACKGROUND AND OBJECTIVES: Pulmonary pleomorphic carcinoma (PPC) is a rare and aggressive subtype of lung cancer. Programmed cell death-ligand 1 (PD-L1) expression may be induced in a variety of malignant tumors, but its prognostic implication in PPC remains unclear. METHODS: Twenty-six patients with surgically resected PPC were retrospectively reviewed. Immuno-histochemical staining was used to detect PD-L1 expression, and PD-L1 status was classified into "high" or "low" according to the percentage of tumor cells (TCs) expressing PD-L1 (tumor proportion score, TPS). RESULTS: PD-L1 expression was positive in 20 (76.9%) patients at the cut-off TPS value of 1%. A receiver-operating characteristic (ROC) analysis showed that the optimal cut-off value was 15% for prediction of cancer-specific death with the area under ROC curve of 0.701 (P = 0.107). High PD L1 expression was associated with a favorable overall survival (100% vs 45.9% at 5 years; P = 0.046) as well as a favorable cancer-specific survival (88.9% vs 37.5% at 5 years; P = 0.012). A multivariate analysis indicated a trend toward a favorable prognosis associated with high PD-L1 expression (hazard ratio [HR], 0.254 [95% confidence interval, 0.054-1.200]; P = 0.084). CONCLUSIONS: PD-L1 expression was positive in most PPC cases, and high PD-L1 expression may predict a favorable prognosis in resected PPC. PMID- 29601634 TI - Intraoperative identification and definition of "functional" lymphatic collecting vessels for supermicrosurgical lymphatico-venous anastomosis in treating lymphedema patients. AB - BACKGROUND: For current lymphatico-venous anastomosis (LVA), the identification of "functional" lymphatic collecting vessels (LCVs) is mainly based on indocyanine green (ICG) lymphography. However, some of the non-ICG enhanced LCVs utilized for LVA were found to have visual lymphatic flow. OBJECTIVES: Should non ICG enhanced, but flow-positive LCVs be considered functional as well? METHODS: A retrospective study with 56 consecutive lymphedema patients (8 male/48 female) received LVA. LCVs were observed after ICG injection, before/after LVAs were performed. ICG enhancement and lymphatic flow in the LCVs were recorded and grouped as: Group A: all LCVs ICG(+) and flow(+); Group B: all LCVs ICG(+) and some were flow(+); Group C: some ICG(+) and some flow(+) LCVs; Group D: all LCVs ICG(-)but all flow(+); and Group E: all LCVs were both ICG(-) and flow(-). RESULTS: A total of 366 LCVs were identified, averaging 8.2 LVAs, 6.5 LCVs, and 4.7 veins per patient. A total of 33 LVAs were performed with 27 LCVs with no ICG enhancement from 7 patients (Group D). These patients were satisfied with their lymphedema improvements. CONCLUSION: Lymphatic flow-positive but non-ICG enhanced LCVs, should also be considered as functional, thereby maximizing the number of functional LCVs for LVA. PMID- 29601635 TI - Fatal Poisoning with Both Dichlorvos and Phenthoate. AB - Organophosphates are widely used as pesticides. However, organophosphates are occasionally orally ingested to commit suicide. In this case, a man in his late 80s committed suicide by ingesting both dichlorvos and phenthoate. Autopsy findings revealed a characteristic volatile odor from his mouth, stomach, lungs, liver, and kidneys. The esophageal mucosa was denatured and had lost elasticity. Serum cholinesterase activity was 9 IU/L. Toxicological analyses performed using high-performance liquid chromatography-tandem mass spectrometry revealed that dichlorvos concentrations in the left and right cardiac blood samples were 11.6 and 4.6 MUg/mL, respectively. Phenthoate concentrations in the left and right cardiac blood samples were 5.8 and 0.51 MUg/mL, respectively. The total amounts of dichlorvos and phenthoate in the stomach were 7.35 and 4.55 g, respectively. The case history, autopsy findings, and toxicological analyses indicated that the cause of death was acute fatal poisoning after oral ingestion of both dichlorvos and phenthoate. PMID- 29601636 TI - Mean residual life regression with functional principal component analysis on longitudinal data for dynamic prediction. AB - Predicting patient life expectancy is of great importance for clinicians in making treatment decisions. This prediction needs to be conducted in a dynamic manner, based on longitudinal biomarkers repeatedly measured during the patient's post-treatment follow-up period. The prediction is updated any time a new biomarker measurement is obtained. The heterogeneity across patients of biomarker trajectories over time requires flexible and powerful approaches to model noisy and irregularly measured longitudinal data. In this article, we use functional principal component analysis (FPCA) to extract the dominant features of the biomarker trajectory of each individual, and use these features as time-dependent predictors (covariates) in a transformed mean residual life (MRL) regression model to conduct dynamic prediction. Simulation studies demonstrate the improved performance of the transformed MRL model that includes longitudinal biomarker information in the prediction. We apply the proposed method to predict the remaining time expectancy until disease progression for patients with chronic myeloid leukemia, using the transcript levels of an oncogene, BCR-ABL. PMID- 29601638 TI - Undiagnosed Congenital Heart Defects as a Cause of Sudden, Unexpected Death in Children. AB - Despite advances in the diagnosis and treatment of congenital heart defects (CHDs), these defects are still an important cause of sudden, unexpected death in young children. This retrospective study identified 64 cases of CHDs presenting as a cause of sudden, unexpected death in a busy, urban Medical Examiner's Office pediatric population between 2006 and 2016. The majority of cases (52 of 64, 81%) were infants. Interestingly, 52% of cases were undiagnosed prior to autopsy. Ventricular septal defects and atrioventricular septal defects were the most common simple (14%) and complex (17%) malformations observed, respectively. In many cases, there were coexistent simple and/or complex defects. Most of the cases diagnosed with CHD prior to autopsy (48%) had undergone some type of surgical repair. This study highlights the importance of considering undiagnosed CHDs as a cause of sudden, unexpected death, particularly in young children. PMID- 29601637 TI - Using dynamic clamp to quantify pathological changes in the excitability of primary somatosensory neurons. AB - KEY POINTS: Primary somatosensory neurons normally respond to somatic depolarization with transient spiking but can switch to repetitive spiking under pathological conditions. This switch in spiking pattern reflects a qualitative change in spike initiation dynamics and contributes to the hyperexcitability associated with chronic pain. Neurons can be converted to repetitive spiking by adding a virtual conductance using dynamic clamp. By titrating the conductance to determine how much must be added to cause repetitive spiking, we found that small cells are more susceptible to switching (i.e. required less added conductance) than medium-large cells. By measuring how much less conductance is required to cause repetitive spiking when dynamic clamp was combined with other pathomimetic manipulations (e.g. application of inflammatory mediators), we measured how much each manipulation facilitated repetitive spiking. Our results suggest that many pathological factors facilitate repetitive spiking but that the switch to repetitive spiking requires the cumulative effect of many co-occurring factors. ABSTRACT: Primary somatosensory neurons become hyperexcitable in many chronic pain conditions. Hyperexcitability can include a switch from transient to repetitive spiking during sustained somatic depolarization. This switch results from diverse pathological processes that impact ion channel expression or function. Because multiple pathological processes co-occur, isolating how much each contributes to switching the spiking pattern is difficult. Our approach to this challenge involves adding a virtual sodium conductance via dynamic clamp. The magnitude of that conductance was titrated to determine the minimum required to enable rheobasic stimulation to evoke repetitive spiking. The minimum required conductance, termed g- Na *, was re-measured before and during manipulations designed to model various pathological processes in vitro. The reduction in g- Na * caused by each pathomimetic manipulation reflects how much the modelled process contributes to switching the spiking pattern. We found that elevating extracellular potassium or applying inflammatory mediators reduced g- Na * whereas direct hyperpolarization had no effect. Inflammatory mediators reduced g- Na * more in medium-large (>30 MUm diameter) neurons than in small (?30 MUm diameter) neurons, but had equivalent effects in cutaneous and muscle afferents. The repetitive spiking induced by dynamic clamp was also found to differ between small and medium-large neurons, thus revealing latent differences in adaptation. Our study demonstrates a novel way to determine to what extent individual pathological factors facilitate repetitive spiking. Our results suggest that most factors facilitate but do not cause repetitive spiking on their own, and, therefore, that a switch to repetitive spiking results from the cumulative effect of many co-occurring factors. PMID- 29601639 TI - Optimization of Sample Preparation processes of Bone Material for Raman Spectroscopy. AB - Raman spectroscopy has recently been investigated for use in the calculation of postmortem interval from skeletal material. The fluorescence generated by samples, which affects the interpretation of Raman data, is a major limitation. This study compares the effectiveness of two sample preparation techniques, chemical bleaching and scraping, in the reduction of fluorescence from bone samples during testing with Raman spectroscopy. Visual assessment of Raman spectra obtained at 1064 nm excitation following the preparation protocols indicates an overall reduction in fluorescence. Results demonstrate that scraping is more effective at resolving fluorescence than chemical bleaching. The scraping of skeletonized remains prior to Raman analysis is a less destructive method and allows for the preservation of a bone sample in a state closest to its original form, which is beneficial in forensic investigations. It is recommended that bone scraping supersedes chemical bleaching as the preferred method for sample preparation prior to Raman spectroscopy.

PMID- 29601641 TI - Testing cross-phenotype effects of rare variants in longitudinal studies of complex traits. AB - Many gene mapping studies of complex traits have identified genes or variants that influence multiple phenotypes. With the advent of next-generation sequencing technology, there has been substantial interest in identifying rare variants in genes that possess cross-phenotype effects. In the presence of such effects, modeling both the phenotypes and rare variants collectively using multivariate models can achieve higher statistical power compared to univariate methods that either model each phenotype separately or perform separate tests for each variant. Several studies collect phenotypic data over time and using such longitudinal data can further increase the power to detect genetic associations. Although rare-variant approaches exist for testing cross-phenotype effects at a single time point, there is no analogous method for performing such analyses using longitudinal outcomes. In order to fill this important gap, we propose an extension of Gene Association with Multiple Traits (GAMuT) test, a method for cross-phenotype analysis of rare variants using a framework based on the distance covariance. The approach allows for both binary and continuous phenotypes and can also adjust for covariates. Our simple adjustment to the GAMuT test allows it to handle longitudinal data and to gain power by exploiting temporal correlation. The approach is computationally efficient and applicable on a genome-wide scale due to the use of a closed-form test whose significance can be evaluated analytically. We use simulated data to demonstrate that our method has favorable power over competing approaches and also apply our approach to exome chip data from the Genetic Epidemiology Network of Arteriopathy. PMID- 29601642 TI - The plastoquinone pool outside the thylakoid membrane serves in plant photoprotection as a reservoir of singlet oxygen scavengers. AB - The Arabidopsis vte1 mutant is devoid of tocopherol and plastochromanol (PC-8). When exposed to excess light energy, vte1 produced more singlet oxygen (1 O2 ) and suffered from extensive oxidative damage compared with the wild type. Here, we show that overexpressing the solanesyl diphosphate synthase 1 (SPS1) gene in vte1 induced a marked accumulation of total plastoquinone (PQ-9) and rendered the vte1 SPS1oex plants tolerant to photooxidative stress, indicating that PQ-9 can replace tocopherol and PC-8 in photoprotection. High total PQ-9 levels were associated with a noticeable decrease in 1 O2 production and higher levels of Hydroxyplastoquinone (PQ-C), a 1 O2 -specific PQ-9 oxidation product. The extra PQ-9 molecules in the vte1 SPS1oex plants were stored in the plastoglobules and the chloroplast envelopes, rather than in the thylakoid membranes, whereas PQ-C was found almost exclusively in the thylakoid membranes. Upon exposure of wild type plants to high light, the thylakoid PQ-9 pool decreased, whereas the extrathylakoid pool remained unchanged. In vte1 and vte1 SPS1oex plants, the PQ-9 losses in high light were strongly amplified, affecting also the extrathylakoid pool, and PQ-C was found in high amounts in the thylakoids. We conclude that the thylakoid PQ-9 pool acts as a 1 O2 scavenger and is replenished from the extrathylakoid stock. PMID- 29601643 TI - An Integrated Scenario Ensemble-Based Framework for Hurricane Evacuation Modeling: Part 1-Decision Support System. AB - This article introduces a new integrated scenario-based evacuation (ISE) framework to support hurricane evacuation decision making. It explicitly captures the dynamics, uncertainty, and human-natural system interactions that are fundamental to the challenge of hurricane evacuation, but have not been fully captured in previous formal evacuation models. The hazard is represented with an ensemble of probabilistic scenarios, population behavior with a dynamic decision model, and traffic with a dynamic user equilibrium model. The components are integrated in a multistage stochastic programming model that minimizes risk and travel times to provide a tree of evacuation order recommendations and an evaluation of the risk and travel time performance for that solution. The ISE framework recommendations offer an advance in the state of the art because they: (1) are based on an integrated hazard assessment (designed to ultimately include inland flooding), (2) explicitly balance the sometimes competing objectives of minimizing risk and minimizing travel time, (3) offer a well-hedged solution that is robust under the range of ways the hurricane might evolve, and (4) leverage the substantial value of increasing information (or decreasing degree of uncertainty) over the course of a hurricane event. A case study for Hurricane Isabel (2003) in eastern North Carolina is presented to demonstrate how the framework is applied, the type of results it can provide, and how it compares to available methods of a single scenario deterministic analysis and a two-stage stochastic program.

AB - BACKGROUND: Novel treatments with superior benefit-risk profiles are needed to improve the long-term prognosis of patients with inflammatory bowel disease (IBD). Etrolizumab-a monoclonal antibody that specifically targets beta7 integrins-is currently under phase III clinical evaluation in IBD. AIM: This review summarises the available pharmacological and pharmacokinetic/pharmacodynamic data for etrolizumab to provide a comprehensive understanding of its mechanism of action (MOA) and pharmacological effects. METHODS: Published and internal unpublished data from nonclinical and clinical studies with etrolizumab are reviewed. RESULTS: Etrolizumab exerts its effect via a unique dual MOA that inhibits both leucocyte trafficking to the intestinal mucosa and retention within the intestinal epithelial layer. The gut-selectivity of etrolizumab results from its specific targeting of the beta7 subunit of alpha4beta7 and alphaEbeta7 integrins. Etrolizumab does not bind to alpha4beta1 integrin, which mediates lymphocyte trafficking to tissues including the central nervous system, a characteristic underlying its favourable safety with regard to progressive multifocal leucoencephalopathy. Phase I/II studies in patients with ulcerative colitis (UC) showed linear pharmacokinetics when etrolizumab was administered subcutaneously at 100 mg or higher once every 4 weeks. This dose was sufficient to enable full beta7 receptor occupancy in both blood and intestinal tissues of patients with moderate to severe UC. The phase II study results also suggested that patients with elevated intestinal expression of alphaE integrin may have an increased likelihood of clinical remission in response to etrolizumab treatment. CONCLUSION: Etrolizumab is a gut-selective, anti-beta7 integrin monoclonal antibody that may have therapeutic potential for the treatment of IBD. PMID- 29601645 TI - Testing the effects of explicit and implicit bidimensional attitudes on objectively measured speeding behaviour. AB - Bidimensional attitudes have been shown to independently predict behaviour, with the positive dimension of attitude being a stronger predictor of behaviour than the negative dimension (e.g., Elliott, Brewster, et al., 2015, Br. J. Psychol, 106, 656). However, this positivity bias has been demonstrated with explicit attitude measures only and explicit attitude measures tap deliberative processes rather than automatic processes, which are known to be important in the execution of many behaviours. The aim of this study was to test whether implicit bidimensional attitudes can account for variance in speeding behaviour over and above explicit bidimensional attitudes and whether the positivity bias that is typically found with explicit attitudes generalizes to implicit attitudes. A total of 131 drivers completed a questionnaire measuring their explicit bidimensional attitudes towards speeding. They also completed Implicit Association Tests measuring their implicit bidimensional attitudes. Two weeks later, speeding behaviour was measured using a driving simulator. Explicit attitudes accounted for a significant proportion of the variance in subsequent speeding behaviour. Implicit attitudes accounted for a statistically significant increment to explained variance. The positive dimension of both explicit and implicit attitudes predicted speeding behaviour but the negative dimensions did not. Theoretical implications for understanding the potential attitudinal causes of behaviour and practical implications for behaviour-change interventions are discussed. PMID- 29601646 TI - Enantioseparation of (RS)-fexofenadine and enhanced detection as the diastereomeric amide and anhydride derivatives using liquid chromatography-mass spectrometry. AB - Enantioselective analysis of (RS)-fexofenadine was carried out by achiral HPLC via a derivatization approach using N-hydroxy-benzotriazolyl-(S)-naproxen ester (synthesized for this purpose) and three chirally pure amines as chiral derivatizing reagents. There occurred formation of amide and anhydride types of diastereomeric derivatives. These were separated and isolated by HPLC (analytical and preparative). The structures and configurations were verified via recording full-scan product ion mass spectra using LC-MS, 1 HNMR spectra, Chem3D Pro 12.0 software and the software Gaussian 09 Rev.A.02 program and hybrid density functional B3LYP with 6-31G basis set supplemented with polarimetry. Experimental conditions for synthesis and separations were optimized and the elution order was established. Analytical separation was performed on a C18 analytical column with different ratios of MeCN-TEAP buffer and MeOH-TEAP buffer (v/v) adjusted to pH 7.5 as mobile phase at a flow rate of 0.7 mL min-1 . Detection was performed via UV absorbance at 225 nm. The method was validated in accordance with International Conference on Harmonization guidelines. The detection limits were 6.25 and 7.87 ng mL-1 for first and second eluting diastereomeric derivatives, respectively.

AB - BACKGROUND: Fibrosis-4 index (FIB-4) is a surrogate marker for hepatic fibrosis in hepatitis B virus (HBV) carriers. AIM: To investigate whether FIB-4 index stratifies the risks of adverse liver events. METHODS: A total of 2075 treatment naive, noncirrhotic the patients with chronic HBV infection were included. Most of them (82.1%) were HBeAg-negative patients and their baseline FIB-4 levels were explored to stratify the risks of cirrhosis, cirrhosis-related complications and liver-related mortality. RESULTS: During a mean follow-up period of 15.47 years, we found a higher baseline FIB-4 index was associated with increased incidence rates of cirrhosis in addition to the common host and viral factors. Patients with FIB-4 >1.29, compared to those with FIB-4 <1.29, were associated with increased risks of cirrhosis, cirrhosis-related complications and liver-related mortality with the hazard ratio (95% confidence interval) of 6.19 (4.76-8.05), 6.88, (3.68-12.86) and 7.79, (4.54-13.37) respectively. Within the first 3 years of follow-up, FIB-4 remained stable and its kinetics were consistently associated with the develoopment of adverse liver events. Furthermore, FIB-4 index of 1.29 was able to stratify all the risks of adverse liver events even in HBeAg-negative patients with a low risk of disease progression (HBV DNA <2000 IU/mL, HBsAg <1000 IU/mL and ALT <40 U/L). Only 1 patient with FIB-4 index <1.29 developed cirrhosis but not other events within 15 years of follow-up. CONCLUSIONS: In noncirrhotic patients with chronic HBV infection, a higher FIB-4 index was associated with increased risks of adverse liver events. FIB-4 index <1.29 is useful for the prediction of the lowest risks of disease progression.

PMID- 29601650 TI - Prior knowledge of category size impacts visual search. AB - Prior research has shown that category search can be similar to one-item search (as measured by the N2pc ERP marker of attentional selection) for highly familiar, smaller categories (e.g., letters and numbers) because the finite set of items in a category can be grouped into one unit to guide search. Other studies have shown that larger, more broadly defined categories (e.g., healthy food) also can elicit N2pc components during category search, but the amplitude of these components is typically attenuated. Two experiments investigated whether the perceived size of a familiar category impacts category and exemplar search. We presented participants with 16 familiar company logos: 8 from a smaller category (social media companies) and 8 from a larger category (entertainment/recreation manufacturing companies). The ERP results from Experiment 1 revealed that, in a two-item search array, search was more efficient for the smaller category of logos compared to the larger category. In a four-item search array (Experiment 2), where two of the four items were placeholders, search was largely similar between the category types, but there was more attentional capture by nontarget members from the same category as the target for smaller rather than larger categories. These results support a growing literature on how prior knowledge of categories affects attentional selection and capture during visual search. We discuss the implications of these findings in relation to assessing cognitive abilities across the lifespan, given that prior knowledge typically increases with age. PMID- 29601651 TI - Calpain-2 triggers prostate cancer metastasis via enhancing CRMP4 promoter methylation through NF-kappaB/DNMT1 signaling pathway. AB - BACKGROUND: Metastasis is the major cause of cancer-specific death in patients with prostate cancer (PCa). We previously reported that collapsing response mediator protein-4 (CRMP4) is a PCa metastasis-suppressor gene and the hypermethylation in CRMP4 promoter is responsible for the transcription repression in metastatic PCa. However, the underlying mechanisms remain unknown. In this study, we aimed to investigate the role of calpain-2 in CRMP4 promoter hypermethylation and its functional modulation in PCa metastasis. METHODS: Calpain-2 expression in PCa tissues (n = 87) and its specific mechanisms of functional modulation in CRMP4 expression via limited enzymatic cleavage was investigated. We then focused on the cooperative crosstalk of calpain-2 and NF kappaB RelA/p65 in CRMP4 promoter methylation for the initiation of PCa metastasis. Statistical differences between groups were determined using a two tailed Student's t-test. P < 0.05 indicated statistically significant. RESULTS: Calpain-2 was differentially upregulated in metastatic PCa compared with localized PCa. Moreover, calpain-2 cleaved CRMP4 into the N-terminally fragment which promoted migration and invasion in PCa cells via nuclear translocation and activation of E2F1-mediated DNA methyltransferase 1 (DNMT1) expression. NF-kappaB RelA/p65 recruited DNMT1 to bind to and methylate CRMP4 promoter in which Serine276 phosphorylation of p65 was essential. Furthermore, CRMP4 exhibited anti metastatic function via inhibiting the expression of VEGFC through Semaphorin3B Neuropilin2 signaling. CONCLUSION: Calpain-2 may contribute to the promoter methylation of CRMP4 to repress its transcription, leading to the metastasis of PCa via enhancing VEGFC expression. PMID- 29601652 TI - Comparison of clinical outcomes between variceal and non-variceal gastrointestinal bleeding in patients with cirrhosis. AB - BACKGROUND AND AIM: Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS), and 30-day readmission have yet to be determined. As such, the study aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB. METHODS: This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016. AVB was defined as the presence of varices on endoscopy with high-risk stigmata such as cherry-red spots. Mortality, intensive care unit admission, hospital LOS, and 30-day hospital readmission were recorded and compared among patients with AVB and NVB. RESULTS: A total of 116 patients with cirrhosis were included, 73 with AVB and 43 with NVB. Patients with NVB were older than those with AVB (60.4 +/- 11.1 vs 55.0 +/- 9.5, P = 0.006) whereas patients with AVB were more likely to have known esophageal varices (64.4% vs 37.2%, P = 0.007). Patients with AVB and NVB had similar mortality (15.1% vs 9.3%, P = 0.57), hospital LOS (4.9, interquartile range: 3.6-6.9 days vs 5.0, interquartile range: 2.7-8.3 days), and 30-day readmission rates (19.2% vs 30.2%, P = 0.18). Severity of clinical presentation was associated with increased LOS and overall mortality, including the need for intensive care unit admission, but these were not associated with 30-day readmission rates. CONCLUSION: There were no differences in clinical outcomes, including mortality, in cirrhotic patients admitted with AVB and NVB.

AB - BACKGROUND: Angiostrongylosis is considered as emerging disease in dogs in Belgium. Detection of first-stage larvae in feces using the Baermann method has an imperfect sensitivity. OBJECTIVES: Investigation of efficacy of noninvasive blood and fecal diagnostic tests in comparison with PCR on bronchoalveolar lavage (BAL) material in a small series of coughing or dyspnoeic dogs naturally infected with Angiostrongylus vasorum. ANIMALS: Seven dogs with angiostrongylosis. METHODS: Retrospective study. Dogs with cough, exercise intolerance and dyspnea of 2- to 8-week duration. Diagnostic methods used included Baermann analysis, AngioDetect rapid assay, ELISAs for detection of circulating antigen and specific antibodies and qPCR on BAL material. RESULTS: Baermann analysis, AngioDetect rapid assay, antigen ELISA, antibody ELISA, and qPCR on BAL material were positive in 3/7, 2/7, 3/6, 6/6, and 7/7 dogs, respectively. ELISA for antibodies or qPCR on BAL material were essential for definitive diagnosis in 3 dogs. Relative sensitivities of AngioDetect rapid assay, Baermann analysis, and ELISA for antigen detection were lower than 50% compared with ELISA for antibodies or qPCR on BAL material. CONCLUSION AND CLINICAL IMPORTANCE: In this small clinical series, Baermann analysis and AngioDetect rapid assay failed to confirm the diagnosis in some dogs. Therefore, ELISA for antibody detection and qPCR on BAL material should strongly be considered in clinically suspected dogs when antigen detection methods (AngioDetect or ELISA) and Baermann analysis are negative. PMID- 29601654 TI - Predictors of anxiety and depression 2 years following treatment in uveal melanoma survivors. AB - OBJECTIVE: We examined the role of posttreatment symptoms and functional problems and of worry about recurrent disease (WREC) in predicting probable anxiety and depression cases 24 months after diagnosis in survivors of posterior uveal melanoma. We examined whether WREC mediates links between symptoms, functional problems, and probable anxiety and depression cases. METHODS: Prospective cohort study of 261 treated uveal melanoma survivors 6, 12, and 24 months after diagnosis. Hierarchical logistic regression analyses predicting anxiety and depression 24 months after diagnosis identified by Hospital Anxiety and Depression Scale cutoff scores. Symptoms, functional problems, and WREC 6-month posttreatment were entered into the analyses as predictors, then the same variables at 12 months. We controlled anxiety or depression at 6 and 12 months and chromosome 3 status, which accurately predicts 10-year survival. Mediation of links between 6-month symptoms and functional problems and 24-month anxiety and depression by 12-month WREC was tested. RESULTS: Anxiety caseness at 24 months was predicted by 6-month ocular irritation, headache, and functional problems and 12-month WREC. Depression caseness at 24 months was predicted by 6-month headache and functional problems. Worry about recurrent disease at 12 months mediated prediction of anxiety caseness by 6-month symptoms and functional problems. Chromosome 3 status predicted neither anxiety nor depression. CONCLUSIONS: Survivors reporting symptoms, functional problems, and WREC should be monitored for anxiety and depression. Appropriate reassurance that symptoms do not signify future disease might help prevent anxiety. PMID- 29601655 TI - Translucent windows: how uncertainty in competitive interactions impacts detection of community pattern. AB - Traits can provide a window into the mechanisms that maintain coexistence among competing species. Recent theory suggests that competitive interactions will lead to groups, or clusters, of species with similar traits. However, theoretical predictions typically assume complete knowledge of the map between competition and measured traits. These assumptions limit the plausible application of these patterns for inferring competitive interactions in nature. Here, we relax these restrictions and find that the clustering pattern is robust to contributions of unknown or unobserved niche axes. However, it may not be visible unless measured traits are close proxies for niche strategies. We conclude that patterns along single niche axes may reveal properties of interspecific competition in nature, but detecting these patterns requires natural history expertise firmly tying traits to niches. PMID- 29601656 TI - A Multicontrolled Enamine Configurational Switch Undergoing Dynamic Constitutional Exchange. AB - A multiresponsive enamine-based molecular switch is presented, in which forward/backward configurational rotation around the C=C bond could be precisely controlled by the addition of an acid/base or metal ions. Fluorescence turn on/off effects and large Stokes shifts were observed while regulating the switching process with CuII . The enamine functionality furthermore enabled double dynamic regimes, in which configurational switching could operate in conjunction with constitutional enamine exchange of the rotor part. This behavior was used to construct a prototypical dynamic covalent switch system through enamine exchange with primary amines. The dynamic exchange process could be readily turned on/off by regulating the switch status with pH. PMID- 29601657 TI - Health care costs of depression in patients diagnosed with cancer. AB - OBJECTIVE: Depression is common among patients diagnosed with cancer. Patients with cancer and depression use more health care services compared with nondepressed cancer patients. The current study seeks to estimate the added cost of depression in cancer patients in the first year after cancer diagnosis. METHODS: Health care charges were obtained for 2051 depressed and 11 182 nondepressed patients with an International Classification of Diseases, Ninth Revision, diagnosis of cancer in the 2014 calendar year from the University of California San Diego Healthcare System. The annual health care charges for cancer patients with and without depression were analyzed using generalized linear models with a log-link function and gamma distribution, covarying for age, sex, race/ethnicity, comorbid diseases, and presence of metastatic disease. Total cost data were broken down into several categories including ambulatory care, emergency department visits, and hospital visits. RESULTS: Depressed cancer patients had total annual health care charges that were 113% higher than nondepressed cancer patients (B = 0.76; P < .001). The estimated mean charges for depressed patients were $235 337 compared with $110 650 for nondepressed patients. Depressed cancer patients incurred greater charges than nondepressed patients in ambulatory care (B = 0.70; P < .001), emergency department charges (B = 0.31; P < .001), and hospital charges (B = 0.39; P < .001). CONCLUSIONS: Depressed cancer patients incur significantly higher health care charges across multiple cost categories including ambulatory care, emergency department visits, and hospital visits. Future research should investigate if interventions for detecting and treating depression are effective for reducing health care use and costs in cancer patients. PMID- 29601658 TI - Chromatographic characterisation of 11 phytocannabinoids: Quantitative and fit-to purpose performance as a function of extra-column variance. AB - INTRODUCTION: Cannabis sativa L. (cannabis) is utilised as a therapeutic and recreational drug. With the legalisation of cannabis in many countries and the anticipated regulation of potency that will accompany legalisation, analytical testing facilities will require a broadly applicable, quantitative, high throughput method to meet increased demand. Current analytical methods for the biologically active components of cannabis (phytocannabinoids) suffer from low throughput and/or an incomplete complement of relevant phytocannabinoids. OBJECTIVE: To develop a rapid, quantitative and broadly applicable liquid chromatography-tandem mass spectrometry analytical method for 11 phytocannabinoids in cannabis with acidic and neutral character. METHODOLOGY: Bulk diffusion coefficients were calculated using the Taylor-Aris open tubular method, with four reference compounds used to validate the experimental set-up. Three columns were quantitatively evaluated using van Deemter plots and fit-to purpose performance metrics. Low (1.2 MUL2 ) and standard (3.6 MUL2 ) extra column variance ultra-high pressure liquid chromatography (UPLC) configurations were contrasted. Method performance was demonstrated with methanolic cannabis flower extracts. RESULTS: Bulk diffusion coefficients and van Deemter plots for 11 phytocannabinoids are reported. The developed chromatographic method includes the challenging Delta8 /Delta9 -tetrahydrocannabinol isobars and, at 6.5 min, is faster than existing methods targeting similar panels of biologically active phytocannabinoids. CONCLUSIONS: The bulk diffusion coefficients and van Deemter curves informed the development of a rapid quantitative method and will facilitate potential expansion to include additional compounds, including synthetic cannabinoids. The developed method can be implemented with low or standard extra-column variance UPLC configurations. PMID- 29601659 TI - Promoting active ageing in older people with mental disorders living in the community: An integrative review. AB - AIM: To critically synthesize the evidence in relation to the promotion of active ageing in older people, including those with mental disorders. BACKGROUND: Approximately 15% of older people aged 60 and above are experiencing a mental disorder. However, they are commonly unrecognized from health care providers. DESIGN: This study is an integrative review. Articles published between January 2002 and March 2017 in English and in Thai were identified through searches of the databases CINAHL, MEDLINE, EMBASE, PsycINFO, and Thai LIS, as well as through manual searching. Methodologically high-quality research articles were included if they addressed the promotion of active ageing and related concepts, the impact of mental disorders on active ageing and related concepts, the perspective of older people regarding active ageing, and issues related to working with older people with mental health problems living in the community. RESULTS: A total of 18 articles were included. The findings show that there is little evidence regarding the promotion of active ageing in older people with mental disorders. Older people with mental disorders were less likely to achieve successful ageing compared with those without mental disorders, suggesting they need support from health care providers. However, there are several barriers to care and working with older people with mental disorders at the community level. CONCLUSION: Of concern is that health professionals focus on the physical health of older people while mental health issues are overlooked.

AB - An unprecedented silver-catalyzed difunctionalization of the isocyano group with cyclic oximes is described. This method allows efficient and atom-economic assembly of a vast array of structurally novel and interesting pyrimidinediones, and tolerates a range of functionalities. The resulting products can be easily converted into some useful compounds. Furthermore, the method can also be applied for the late-stage modification of a few biologically active molecules. PMID- 29601661 TI - Recent advances in gene-enhanced bone tissue engineering. AB - The loss of bone tissue represents a critical clinical condition that is frequently faced by surgeons. Substantial progress has been made in the area of bone research, providing insight into the biology of bone under physiological and pathological conditions, as well as tools for the stimulation of bone regeneration. The present review discusses recent advances in the field of gene enhanced bone tissue engineering. Gene transfer strategies have emerged as highly effective tissue engineering approaches for supporting the repair of the musculoskeletal system. By contrast to treatment with recombinant proteins, genetically engineered cells can release growth factors at the site of injury over extended periods of time. Of particular interest are the expedited technologies that can be applied during a single surgical procedure in a cost effective manner, allowing translation from bench to bedside. Several promising methods based on the intra-operative genetic manipulation of autologous cells or tissue fragments have been developed in preclinical studies. Moreover, gene therapy for bone regeneration has entered the clinical stage with clinical trials for the repair of alveolar bone. Current trends in gene-enhanced bone engineering are also discussed with respect to the movement of the field towards expedited, translational approaches. It is possible that gene-enhanced bone tissue engineering will become a clinical reality within the next few years. PMID- 29601662 TI - African-American men and prostate cancer-specific mortality: a competing risk analysis of a large institutional cohort, 1989-2015. AB - Significant racial disparities in prostate cancer (PCa) outcomes have been reported, with African-American men (AAM) more likely to endure adverse oncologic outcomes. Despite efforts to dissipate racial disparities in PCa, a survival gap persists and it remains unclear to what extent this disparity can be explained by known clinicodemographic factors. In this study, we leveraged our large institutional database, spanning over 25 years, to investigate whether AAM continued to experience poor PCa outcomes and factors that may contribute to racial disparities in PCa. A total of 7307 patients diagnosed with PCa from 1989 through 2015 were included. Associations of race and clinicodemographic characteristics were analyzed using chi-square for categorical and Mann-Whitney U test for continuous variables. Racial differences in prostate cancer outcomes were analyzed using competing risk analysis methods of Fine and Gray. Median follow-up time was 106 months. There were 2304 deaths recorded, of which 432 resulted from PCa. AAM were more likely to be diagnosed at an earlier age (median 60 vs. 65 years, P = <0.001) and were more likely to have >=1 comorbidities (13.6% vs. 7.5%, P < 0.001). In a multivariate competing risk model, adjusted for baseline covariates, AAM experienced significantly higher risk of PCSM compared to NHW men (HR, 1.62, 95% CI, 1.02-2.57, P = 0.03) NHW. Among men diagnosed at an older age (>60 years), racial differences in PCSM were more pronounced, with AAM experiencing higher rates of PCSM (HR, 2.05, 95% CI, 1.26-3.34, P = 0.003). After adjustment of clinicodemographic and potential risk factors, AAM continue to experience an increased risk of mortality from PCa, especially older AAM. Furthermore, AAM are more likely to be diagnosed at an early age and more likely to have higher comorbidity indices. PMID- 29601663 TI - Survival benefit of lymph node dissection in surgery for colon cancer in elderly patients: A multicenter propensity score-matched study in Japan. AB - INTRODUCTION: In surgery for elderly patients with colorectal cancer, it is unclear whether radical lymph node (LN) dissection safely offers a survival benefit. The aim of the study was to evaluate the impact of the LN yield in elderly patients undergoing surgery for colorectal cancer. METHODS: The subjects were selected from a surgical database of 2065 patients aged >=80 years old who underwent surgery for colorectal cancer at 41 hospitals in Japan between 2003 and 2007. The patients were divided into groups according to the number LN harvested: <12 and >=12. Propensity scores were subsequently matched to balance the baseline characteristics. RESULTS: Of the 954 patients initially selected, 331 were in the <12 LN and 623 were in the >=12 LN group. After cases were matched, 293 patients were allocated to each group, and all covariates were balanced. For short-term outcomes, the time for surgery was longer in the >=12 LN group, but there was no significant difference in morbidity between the groups. Overall, relapse-free and cancer-specific survival rates were higher in the >=12 LN group (P = 0.004, 0.001, and 0.02). CONCLUSIONS: In patients aged >=80 years old with stage II-III colon cancer, harvesting >=12 LN provides a survival benefit, and therefore, limited LN dissection is not recommended in these patients. PMID- 29601664 TI - Plant controls on Late Quaternary whole ecosystem structure and function. AB - Plants and animals influence biomass production and nutrient cycling in terrestrial ecosystems; however, their relative importance remains unclear. We assessed the extent to which mega-herbivore species controlled plant community composition and nutrient cycling, relative to other factors during and after the Late Quaternary extinction event in Britain and Ireland, when two-thirds of the region's mega-herbivore species went extinct. Warmer temperatures, plant-soil and plant-plant interactions, and reduced burning contributed to the expansion of woody plants and declining nitrogen availability in our five study ecosystems. Shrub biomass was consistently one of the strongest predictors of ecosystem change, equalling or exceeding the effects of other biotic and abiotic factors. In contrast, there was relatively little evidence for mega-herbivore control on plant community composition and nitrogen availability. The ability of plants to determine the fate of terrestrial ecosystems during periods of global environmental change may therefore be greater than previously thought. PMID- 29601665 TI - Indicators of transitions in biological systems. AB - In the face of global biodiversity declines, predicting the fate of biological systems is a key goal in ecology. One popular approach is the search for early warning signals (EWSs) based on alternative stable states theory. In this review, we cover the theory behind nonlinearity in dynamic systems and techniques to detect the loss of resilience that can indicate state transitions. We describe the research done on generic abundance-based signals of instability that are derived from the phenomenon of critical slowing down, which represent the genesis of EWSs research. We highlight some of the issues facing the detection of such signals in biological systems - which are inherently complex and show low signal to-noise ratios. We then document research on alternative signals of instability, including measuring shifts in spatial autocorrelation and trait dynamics, and discuss potential future directions for EWSs research based on detailed demographic and phenotypic data. We set EWSs research in the greater field of predictive ecology and weigh up the costs and benefits of simplicity vs. complexity in predictive models, and how the available data should steer the development of future methods. Finally, we identify some key unanswered questions that, if solved, could improve the applicability of these methods. PMID- 29601667 TI - Laparoscopic sigmoidectomy in a case of sigmoid colon cancer with situs inversus totalis. AB - Situs inversus totalis (SIT) is a rare anatomic anomaly in which organs in the chest and abdomen exist in a mirror image reversal of their normal positions. SIT can complicate surgical procedures, and few reports have described laparoscopic surgery for colorectal cancer in patients with SIT. Here, we report a case of successful laparoscopic surgery in a patient with SIT and sigmoid colon cancer. Laparoscopic sigmoidectomy involved colonic mobilization with high ligation of the inferior mesenteric vessels and complete mesocolic excision. The operating surgeon stood on the patient's left side, opposite the normal location for sigmoidectomy. By placing a 12-mm trocar in the left iliac fossa and using an automatic endoscopic linear stapler, the operating surgeon was able to perform left-handed colon resection without having to change position or move the laparoscopic monitor mid-procedure. An automatic endoscopic linear stapler is useful for laparoscopic left-side colon surgery in a patient with SIT. PMID- 29601666 TI - Trps1 is associated with the multidrug resistance of lung cancer cell by regulating MGMT gene expression. AB - Multidrug resistance (MDR) often leads to chemotherapy failure of lung cancer and has been linking to the cellular expression of several DNA transcription- and repair-related genes such as Trps1 and MGMT. However, their roles in the formation of MDR are largely unknown. In this study, overexpression/knockdown, luciferase assay and ChIP assay were performed to study the relationship between Trps1 and MGMT, as well as their roles in MDR formation. Our results demonstrated that Trps1 and MGMT expression both increased in drug-resistant lung cancer cell line (H446/CDDP). Silencing of Trps1 resulted in downregulation of MGMT expression and decrease in the multidrug sensitivity of H446/CDDP cells, while Trps1 overexpression exhibited the opposite effects in H446 cells. Ectopic expression of MGMT had no effect on Trps1 expression, but enhanced the IC50 values of H446 cells or rescued the IC50 values of Trps1-silenced H446/CDDP cells in treatment of multidrug. Our data further showed that, mechanistically, Trps1 acted as a transcription activator that directly induced MGMT transcription by binding to the MGMT promoter. Taken together, we consider that upregulation of Trps1 induces MGMT transcription contributing to the formation of MDR in lung cancer cells. Our findings proved potential targets for reversing MDR in clinical chemotherapy of lung cancer. PMID- 29601668 TI - Calcium plus magnesium indicates digestibility: the significance of the second major axis of plant chemical variation for ecological processes. AB - Plant variation in nutrient concentrations encompasses two major axes. The first is connected to nitrogen (N) and phosphorus (P), reflects growth rate and has been designated as the leaf economics spectrum (LES) while the second follows the gradient in calcium (Ca) and magnesium (Mg) and mirrors cell structural differences. Here, we tested in grasslands whether the sum Ca + Mg concentrations is a better indicator of digestibility than LES constituents. Structural equation modelling revealed that the total effect size of N (0.30) on digestibility was much lower than that of Ca + Mg (0.58). The N effect originated predominantly from sampling date (biomass ageing), while the Ca + Mg effect largely from phylogenetic composition (proportion of monocots). Thus, plant variation in partially substitutable divalent cations seems to play a significant role in biomass digestion by ruminants. This finding contests, together with litter decomposition studies, the prominent role of the LES for understanding both fundamental ecological processes. PMID- 29601669 TI - Canalisation in the wild: effects of developmental conditions on physiological traits are inversely linked to their association with fitness. AB - Ecological conditions affect fitness, but mechanisms causing such effects are not well known, while evolved responses to environmental variation may depend on the underlying mechanisms. Consequences of environmental conditions vary strongly between traits, but a framework to interpret such variation is lacking. We propose that variation in trait response may be explained by differential canalisation, with traits with larger fitness effects showing weaker responses to environmental perturbations due to preferential resource allocation to such traits. We tested the canalisation hypothesis using brood size manipulation in wild jackdaw nestlings in which we measured eight physiological traits (mainly oxidative stress markers), and two feather traits. For each trait, we estimated manipulation response and association with fitness (over-winter survival). As predicted, a strong negative correlation emerged between manipulation response and association with fitness (r =-0.76). We discuss the consequences of differential trait canalisation for the study of mechanisms mediating environmental effects on fitness. PMID- 29601670 TI - Species-area relationships and biodiversity loss in fragmented landscapes. AB - To estimate species loss from habitat destruction, ecologists typically use species-area relationships, but this approach neglects the spatial pattern of habitat fragmentation. Here, we provide new, easily applied, analytical methods that place upper and lower bounds on immediate species loss at any spatial scale and for any spatial pattern of habitat loss. Our formulas are expressed in terms of what we name the 'Preston function', which describes triphasic species-area relationships for contiguous regions. We apply our method to case studies of deforestation and tropical tree species loss at three different scales: a 50 ha forest plot in Panama, the tropical city-state of Singapore and the Brazilian Amazon. Our results show that immediate species loss is somewhat insensitive to fragmentation pattern at small scales but highly sensitive at larger scales: predicted species loss in the Amazon varies by a factor of 16 across different spatial structures of habitat loss. PMID- 29601672 TI - MRI-guided interventional natural killer cell delivery for liver tumor treatment. AB - While natural killer (NK) cell-based adoptive transfer immunotherapy (ATI) provides only modest clinical success in cancer patients. This study was hypothesized that MRI-guided transcatheter intra-hepatic arterial (IHA) infusion permits local delivery to liver tumors to improve outcomes during NK-based ATI in a rat model of hepatocellular carcinoma (HCC). Mouse NK cells were labeled with clinically applicable iron nanocomplexes. Twenty rat HCC models were assigned to three groups: transcatheter IHA saline infusion as the control group, transcatheter IHA NK infusion group, and intravenous (IV) NK infusion group. MRI studies were performed at baseline and at 24 h, 48 h, and 8 days postinfusion. There was a significant difference in tumor R2* values between baseline and 24 h following the selective transcatheter IHA NK delivery to the tumors (P = 0.039) when compared to IV NK infusion (P = 0.803). At 8 days postinfusion, there were significant differences in tumor volumes between the control, IV, and IHA NK infusion groups (control vs. IV, P = 0.196; control vs. IHA, P < 0.001; and IV vs. IHA, P = 0.001). Moreover, there was a strong correlation between tumor R2* value change (?R2*) at 24 h postinfusion and tumor volume change (?volume) at 8 days in IHA group (R2 = 0.704, P < 0.001). Clinically applicable labeled NK cells with 12-h labeling time can be tracked by MRI. Transcatheter IHA infusion improves NK cell homing efficacy and immunotherapeutic efficiency. The change in tumor R2* value 24 h postinfusion is an important early biomarker for prediction of longitudinal response. PMID- 29601671 TI - The importance of greater speed in drug development for advanced malignancies. AB - It takes on average 6-12 years to develop new anticancer drugs from discovery to approval. Effective new agents prolong survival. To demonstrate the importance of rapid drug approval, we calculated life-years potentially saved if selected agents were approved more rapidly. As illustrative examples, we used 27 trials documenting improvements in survival. We multiplied improvement in median survival by numbers of patients dying annually and multiplied this by number of years from drug discovery until approval. For every year by which time to drug approval could have been shortened, there would have been a median number of life years potentially saved of 79,920 worldwide per drug. Median number of life-years lost between time of drug discovery and approval was 1,020,900 per example. If we were able to use available opportunities to decrease the time required to take a drug from discovery to approval to 5 years, the median number of life-years saved per example would have been 523,890 worldwide. Various publications have identified opportunities to speed drug development without sacrificing patient safety. While many investigational drugs prove to be ineffective, some significantly prolong survival and/or reduce suffering. These illustrative examples suggest that a substantial number of life-years could potentially be saved by increasing the efficiency of development of new drugs for advanced malignancies. PMID- 29601673 TI - Tumor-derived extracellular vesicles activate primary monocytes. AB - Tumor cells educate immune effector cells in their vicinity by releasing factors that manipulate their phenotype and function. In fact, the thus generated immunosuppressive tumor microenvironment constitutes an integral part and a hallmark of solid tumors and contributes significantly to tumor development and immune escape. It has long been thought that soluble factors like prostaglandin E2 and TGF-beta are the main mediators of these effects. But tumor cells also constantly release large number of extracellular vesicles (EVs), which are important conveyors of immune responses. We show here that tumor-derived EVs interact with primary monocytes and induce an activated phenotype, which is also observed in tumor-associated macrophages. Thus, both tumor-derived EVs and soluble factors together collaborate to form the immunosuppressive milieu of the tumor environment. PMID- 29601674 TI - RFX1 participates in doxorubicin-induced hepatitis B virus reactivation. AB - Cytotoxic chemotherapy drugs, including doxorubicin, can directly promote hepatitis B virus (HBV) replication, but the mechanism has not been fully clarified. This study investigated the potential mechanism underlying the cytotoxic chemotherapy-mediated direct promotion of HBV replication. We found that HBV replication and regulatory factor X box 1 gene (RFX1) expression were simultaneously promoted by doxorubicin treatment. The amount of RFX1 bound to the HBV enhancer I was significantly increased under doxorubicin treatment. Furthermore, the activity of doxorubicin in promoting HBV replication was significantly attenuated when the expression of endogenous RFX1 was knocked down, and the EP element of HBV enhancer I, an element that mediated the binding of RFX1 and HBV enhancer I, was mutated. In addition, two different sequences of the conserved EP element were found among HBV genotypes A-D, and doxorubicin could promote the replication of HBV harboring either of the conserved EP elements. Here, a novel pathway in which doxorubicin promoted HBV replication via RFX1 was identified, and it might participate in doxorubicin-induced HBV reactivation. These findings would be helpful in preventing HBV reactivation during anticancer chemotherapy. PMID- 29601676 TI - Our voices united: ADEE and ADEA. PMID- 29601675 TI - Impact of scientific and technological advances. AB - Advancements in research and technology are transforming our world. The dental profession is changing too, in the light of scientific discoveries that are advancing biological technology-from new biomaterials to unravelling the genetic make-up of the human being. As health professionals, we embrace a model of continuous quality improvement and lifelong learning. Our pedagogical approach to incorporating the plethora of scientific-technological advancements calls for us to shift our paradigm from emphasis on skill acquisition to knowledge application. The 2017 ADEE/ADEA workshop provided a forum to explore and discuss strategies to ensure faculty, students and, ultimately, patients are best positioned to exploit the opportunities that arise from integrating new technological advances and research outcomes. Participants discussed methods of incorporating the impact of new technologies and research findings into the education of our dental students. This report serves as a signpost of the way forward and how to promote incorporation of research and technology advances and lifelong learning into the dental education curriculum. PMID- 29601677 TI - Guest editorial: Inspiration through collaboration. PMID- 29601678 TI - Interprofessional education in dental education: An international perspective. AB - Interprofessional collaborative care (IPC) is defined as working within and across healthcare disciplines and is considered essential to achieve a more inclusive, patient-centred care, provide a means to support patient safety and address global healthcare provider shortages. Interprofessional education (IPE) provides the knowledge and experience students need to achieve these goals. ADEE/ADEA held a joint international meeting 8-9 May 2017, with IPE being one of four topic areas discussed. The highly interactive workshop format, where "everyone was an expert," supported discussion, sharing and creative problem solving of over seventy-one participants from twenty-nine countries. IPE participants broke out into five groups over a two-day period discussing three main areas: challenges and barriers to implementing IPE within their institution or country; discussion of successful models of introducing and assessing IPE initiatives, and exploring best practices and next steps for implementation for each group member. A mind-mapping model was used to graphically display participants' thoughts and suggestions. Key themes, revealed through the visual mind maps and discussion, included the following: IPE should lead to and enhance patient-centred care; student involvement is key to IPE success; faculty development and incentives can facilitate adoption and implementation of IPE; the role of a "champion" and leadership structure and commitment is important to move IPE forward; and IPE must be tailored to the unique issues found in each country. Overall, there was a high level of interest to continue both collaboration and discussion to learn from others beyond the London meeting. PMID- 29601679 TI - Shaping the future of dental education: Caries as a case-study. AB - This study reports on the full-day workshop "The Shape of The Future of Dental Education for Dental Caries-and how we get there" held immediately prior to the May 2017 ADEE/ADEA/King's College London meeting "Shaping the Future of Dental Education." A standardised, evidence-led Core Curriculum in Cariology (CCC) was developed jointly and systematically by ORCA and ADEE, starting in 2010. At the same time, the ICDAS Foundation was developing a comprehensive caries management system, ICCMSTM. The workshop reported on what has been achieved on a global basis by many building on these initiatives. The CCC has been, or is currently being, localised in a number of places around the world and has, in some countries, been successfully implemented. There are also other areas which are struggling more with the logistics of introducing it. The workshop presented geographical perspectives and experiences on implementing the CCC from Colombia, the United States and Europe, as well as professional perspectives from hygienists, students and policymakers. The workshop then considered the future of the CCC and the roles of Interprofessional Education, Technology, Global Networking and Assessment in a Global Context in 4 breakout groups. Having had reports back and plenary discussion, it was concluded that the caries world has made good progress towards a "futuristic" curriculum with parallel development of a comprehensive, preventive and tooth-preserving caries management system ICCMSTM. The implementation challenge is now to share even more effectively in order to have these developments more widely accepted and adopted worldwide. PMID- 29601680 TI - Global networking: Meeting the challenges, facilitating collaboration. AB - The constant change of information and technology advancement as well as the impact of social media has radically changed the world and education and, in particular, the needs of students, organisations and disadvantaged communities who share the aim of training and providing quality healthcare services. Dental organisations and education centres around the world have recognised the importance of networking in delivering effective education to students, healthcare professionals and communities. Networking is one way to meet the challenges of delivering healthcare education and services. This can be achieved by sharing of resources, expertise, knowledge and experience to benefit all the stakeholders in healthcare delivery. The joint ADEE/ADEA Meeting in London on 8-9 May 2017 has facilitated discussions amongst dental educators from all over the world during a workshop on "Global Networking: the how and why for dental educators." The aim of this workshop was to determine how can dental educators worldwide network to share ideas, experience, expertise and resources to improve both the curricula and the teaching and learning environment. A pre-conference survey was designed and implemented to identify the domains of interest and needs of participants. A structured questionnaire was administered, and this information was used to guide discussions on three main themes: curricula, faculty development and mobility of faculty and students. Four questions were then defined to help group leaders to frame discussions in the four working groups. The four groups engaged in parallel discussions, with the ideas recorded and collated by group leaders, which later served for the thematic analysis across the groups to draw the key points discussed. Overall, a great desire and potential to create a global networking to share and gain support and expertise at individual and organisational level was apparent and the working group has proposed an action plan, acknowledging that it requires great planning, effort and commitment.

PMID- 29601682 TI - Assessment in a global context: An international perspective on dental education. AB - Assessments are widely used in dental education to record the academic progress of students and ultimately determine whether they are ready to begin independent dental practice. Whilst some would consider this a "rite-of-passage" of learning, the concept of assessments in education is being challenged to allow the evolution of "assessment for learning." This serves as an economical use of learning resources whilst allowing our learners to prove their knowledge and skills and demonstrating competence. The Association for Dental Education in Europe and the American Dental Education Association held a joint international meeting in London in May 2017 allowing experts in dental education to come together for the purposes of Shaping the Future of Dental Education. Assessment in a Global Context was one topic in which international leaders could discuss different methods of assessment, identifying the positives, the pitfalls and critiquing the method of implementation to determine the optimum assessment for a learner studying to be a healthcare professional. A post-workshop survey identified that educators were thinking differently about assessment, instead of working as individuals providing isolated assessments; the general consensus was that a longitudinally orientated systematic and programmatic approach to assessment provide greater reliability and improved the ability to demonstrate learning.

AB - The development of a sensor for the rapid and sensitive detection of neurotransmitters could provide a pathway for the diagnosis of neurological diseases, leading to the discovery of more effective treatment methods. We investigate the use of surface enhanced Raman spectroscopy (SERS) based sensors for the rapid detection of melatonin, serotonin, glutamate, dopamine, GABA, norepinephrine, and epinephrine. Previous studies have demonstrated SERS detection of neurotransmitters; however, there has been no comprehensive study on the effect of the metal used as the SERS substrate or the excitation wavelength used for detection. Here, we present the detection of 7 neurotransmitters using both silver and gold nanoparticles at excitation wavelengths of 532, 633, and 785 nm. Over the range of wavelengths investigated, the SERS enhancement on the silver and gold nanoparticles varies, with an average enhancement factor of 105 106. The maximum SERS enhancement occurs at an excitation wavelength of 785 nm for the gold nanoparticles and at 633 nm for the silver nanoparticles. PMID- 29601720 TI - Radiotherapy-Sensitized Tumor Photothermal Ablation Using gamma-Polyglutamic Acid Nanogels Loaded with Polypyrrole. AB - Development of versatile nanoscale platforms for cancer diagnosis and therapy is of great importance for applications in translational medicine. In this work, we present the use of gamma-polyglutamic acid (gamma-PGA) nanogels (NGs) to load polypyrrole (PPy) for thermal/photoacoustic (PA) imaging and radiotherapy (RT) sensitized tumor photothermal therapy (PTT). First, a double emulsion approach was used to prepare the cystamine dihydrochloride (Cys)-cross-linked gamma-PGA NGs. Next, the cross-linked NGs served as a reactor to be filled with pyrrole monomers that were subjected to in situ oxidation polymerization in the existence of Fe(III) ions. The formed uniform PPy-loaded NGs having an average diameter of 38.9 +/- 8.6 nm exhibited good water-dispersibility and colloid stability. The prominent near-infrared (NIR) absorbance feature due to the loaded PPy endowed the NGs with contrast enhancement in PA imaging. The hybrid NGs possessed excellent photothermal conversion efficiency (64.7%) and stability against laser irradiation, and could be adopted for PA imaging and PTT of cancerous cells and tumor xenografts. Importantly, we also explored the cooperative PTT and X-ray radiation-mediated RT for enhanced tumor therapy. We show that PTT of tumors can be more significantly sensitized by RT using the sequence of laser irradiation followed by X-ray radiation as compared to using the reverse sequence. Our study suggests a promising theranostic platform of hybrid NGs that may be potentially utilized for PA imaging and combination therapy of different types of tumors.

AB - For the increasing demand of soft materials with wide ranges of applications, hydrogels have been developed exhibiting variety of functions (e.g., stretchable, self-healing, stimuli-responsive, and etc.). So far, add-in components such as inorganic nanoparticles, carbon materials, clays, and many others to main polymers have been used to achieve various unique functions of hydrogels. The multicomponent hydrogel systems often exhibit batch-dependent inconsistent results and problems in multicomponent mixings, require labors during preparations, and accompany unpredictable cross-talk between the added components. Here, we developed 'single polymeric component', alginate-boronic acid (alginate-BA) hydrogel to overcome the aforementioned problems. It exhibits unprecedented multifunctionalities simultaneously, such as high stretchability, self-healing, shear-thinning, pH- and glucose-sensitivities, adhesive properties, and reshaping properties. Multifunctionalities of alginate-BA hydrogel is resulted from the reversible inter- and intramolecular interactions by dynamic equilibrium of boronic acid-diol complexation and dissociation, which was proved by single molecule level Atomic Force Microscopy (AFM) pulling experiments. We also found that the alginate-BA gel showed enhanced in vivo retentions along gastrointestinal (GI) tract. Our findings suggest that rational polymer designs can result in minimizing the number of a participating component for multifunctional hydrogels, instead of increasing complexity by adding various additional components. PMID- 29601722 TI - Impact of Alternative Jet Fuels on Engine Exhaust Composition During the 2015 ECLIF Ground-Based Measurements Campaign. AB - The application of fuels from renewable sources ("alternative fuels") in aviation is important for the reduction of anthropogenic carbon dioxide emissions, but may also attribute to reduced release of particles from jet engines. The present experiment describes ground-based measurements in the framework of the ECLIF (Emission and Climate Impact of Alternative Fuels) campaign using an Airbus A320 (V2527-A5 engines) burning six fuels of chemically different composition. Two reference Jet A-1 with slightly different chemical parameters were applied and further used in combination with a Fischer-Tropsch synthetic paraffinic kerosene (FT-SPK) to prepare three semi synthetic jet fuels (SSJF) of different aromatic content. In addition, one commercially available fully synthetic jet fuel (FSJF) featured the lowest aromatic content of the fuel selection. Neither the release of nitrogen oxide or carbon monoxide was significantly affected by the different fuel composition. The measured particle emission indices showed a reduction up to 50% (number) and 70% (mass) for two alternative jet fuels (FSJF, SSJF2) at low power settings in comparison to the reference fuels. The reduction is less pronounced at higher operating conditions but the release of particle number and particle mass is still significantly lower for the alternative fuels than for both reference fuels. The observed correlation between emitted particle mass and fuel aromatics is not strict. Here, the H/C ratio is a better indicator for soot emission. PMID- 29601723 TI - Combined Effects of Supersaturation Rates and Doses on the Kinetic-Solubility Profiles of Amorphous Solid Dispersions Based on Water-Insoluble Poly(2 hydroxyethyl methacrylate) Hydrogels. AB - Under nonsink dissolution conditions, the kinetic-solubility profiles of amorphous solid dispersions (ASDs) based on soluble carriers typically exhibit so called "spring-and-parachute" concentration-time behaviors. However, the kinetic solubility profiles of ASDs based on insoluble carriers (including hydrogels) are known to show sustained supersaturation during nonsink dissolution through a matrix-regulated diffusion mechanism by which the supersaturation of the drug is built up gradually and sustained over an extended period without any dissolved polymers acting as crystallization inhibitors. Despite previous findings demonstrating the interplay between supersaturation rates and total doses on the kinetic-solubility profiles of soluble amorphous systems (including ASDs based on dissolution-regulated releases from soluble polymer carriers), the combined effects of supersaturation rates and doses on the kinetic-solubility profiles of ASDs based on diffusion-regulated releases from water-insoluble carriers have not been investigated previously. Thus, the objective of this study is to examine the impacts of total doses and supersaturation-generation rates on the resulting kinetic-solubility profiles of ASDs based on insoluble hydrogel carriers. We employed a previously established ASD-carrier system based on water-insoluble cross-linked-poly(2-hydroxyethyl methacrylate) (PHEMA)-hydrogel beads and two poorly water soluble model drugs: the weakly acidic indomethacin (IND) and the weakly basic posaconazole (PCZ). Our results show clearly for the first time that by using the smallest-particle-size fraction and a high dose (i.e., above the critical dose), it is indeed possible to significantly shorten the duration of sustained supersaturation in the kinetic-solubility profile of an ASD based on a water-insoluble hydrogel carrier, such that it resembles the spring-and-parachute dissolution profiles normally associated with ASDs based on soluble carriers. This generates sufficiently rapid initial supersaturation buildup above the critical supersaturation, resulting in more rapid precipitation. Above this smallest-particle-size range, the matrix-diffusion-regulated nonlinear rate of drug release gets slower, which results in a more modest rate of supersaturation buildup, leading to a maximum supersaturation below the critical-supersaturation level without appreciable precipitation. The area-under-the-curve (AUC) values of the in vitro kinetic-solubility concentration-time profiles were used to correlate the corresponding trends in dissolution enhancement. There are observed monotonic increases in AUC values with increasing particle sizes for high-dose ASDs based on water-insoluble hydrogel matrixes, as opposed to the previously reported AUC maxima at some intermediate supersaturation rates or doses in soluble amorphous systems, whereas in the case of low-dose ASDs (i.e., below the critical dose levels), crystallization would be negligible, leading to sustained supersaturation with all particle sizes (i.e., eventually reaching the same maximum supersaturation) and the smallest particle size reaching the maximum supersaturation the fastest. As a result, the smallest particle sizes yield the largest AUC values in the case of low-dose ASDs based on water-insoluble hydrogel matrixes. In addition to probing the interplay between the supersaturation generation rates and total doses in ASDs based on insoluble hydrogel carriers, our results further support the fact that through either increasing the hydrogel particle size or lowering the total dose to achieve maximum supersaturation still below the critical-supersaturation level, it is possible to avoid drug precipitation so as to maintain sustained supersaturation.

AB - A series of novel hybrid phosphorus ligands were designed and applied to the Rh catalyzed enantioselective anti-Markovnikov hydroformylation of unfunctionalized 1,1-disubstituted alkenes. By employing the new catalyst, linear aldehydes with beta-chirality can be prepared with high yields and enantioselectivities under mild conditions. Furthermore, catalyst loading as low as 0.05 mol % furnished the desired product in good yield and undiminished selectivity, demonstrating the efficiency of this transformation in large-scale synthesis. PMID- 29601725 TI - Enhanced Tribocorrosion Performance of Cr/GLC Multilayered Films for Marine Protective Application. AB - The corrosion and tribology are all closely related to the interface/surface of materials, which are extremely important for the mechanical components used in harsh marine environments. In this work, we fabricated Cr/graphite-like carbon (GLC) multilayered films with different modulation periods on the 316L stainless steels by direct current magnetron sputtering. Tribocorrosion tests in artificial seawater show that the tribocorrosion resistance of the Cr/GLC films is improved as the modulation period decreases from 1000 to 333 nm and then drastically drops with further decreasing to 250 nm. By taking a top-layer thickening strategy for the Cr/GLC film with 250 nm modulation period, the tribocorrosion performance is significantly enhanced. The corresponded mechanisms are discussed in terms of the film structure and electrochemical corrosion behavior. PMID- 29601726 TI - Atmospheric OH Oxidation of Three Chlorinated Aromatic Herbicides. AB - Chlorinated phenoxy acids are a widely used class of herbicides and have been found in remote regions far from sources. However, the atmospheric chemistry of these compounds is poorly understood. We use an oxidative flow reactor coupled to chemical ionization mass spectrometry to investigate OH oxidation of two chlorinated phenoxyacid herbicides (2-methyl-4-chlorophenoxyacetic acid (MCPA) and mecoprop-p) and one chlorinated pyridine herbicide (triclopyr). OH radicals add to the aromatic rings of the three herbicides, produce peroxides via hydrogen abstraction, or fragment at the ether bond. OH oxidation of MCPA produced two potentially toxic compounds: chlorosalicylaldehyde and chlorosalicylic acid. We use standards to validate the detection of these oxidation products by acetate CIMS and quantify the reaction rate. Oxidation of triclopyr produced a known endocrine disruptor, 3,5,6-trichloro-2-pyridinol. Thus, while some OH oxidation products are less toxic than the parent molecules (e.g., C1-5 carboxylic acids), others may be as or more toxic than the parent herbicide. We determine effective rate coefficients for OH addition to the aromatic ring ( kOH) for mecoprop-p of 1.5 (+/-0.7) * 10-12 cm3 molecules-1 s-1 and for MCPA of 2.6 (+/-0.3) * 10-12 cm3 molecules-1 s-1. The atmospheric lifetimes with respect to OH are thus long enough that photochemistry may be relevant to the environmental fate of these pesticides. PMID- 29601727 TI - Paradoxical Effect of Trehalose on the Aggregation of alpha-Synuclein: Expedites Onset of Aggregation yet Reduces Fibril Load. AB - Aggregation of alpha-synuclein is closely connected to the pathology of Parkinson's disease. The phenomenon involves multiple steps, commenced by partial misfolding and eventually leading to mature amyloid fibril formation. Trehalose, a widely accepted osmolyte, has been shown previously to inhibit aggregation of various globular proteins owing to its ability to prevent the initial unfolding of protein. In this study, we have examined if it behaves in a similar fashion with intrinsically disordered protein alpha-synuclein and possesses the potential to act as therapeutic agent against Parkinson's disease. It was observed experimentally that samples coincubated with trehalose fibrillate faster compared to the case in its absence. Molecular dynamics simulations suggested that this initial acceleration is manifestation of trehalose's tendency to perturb the conformational transitions between different conformers of monomeric protein. It stabilizes the aggregation prone "extended" conformer of alpha-synuclein, by binding to its exposed acidic residues of the C terminus. It also favors the beta rich oligomers once formed. Interestingly, the total fibrils formed are still promisingly less since it accelerates the competing pathway toward formation of amorphous aggregates. PMID- 29601728 TI - Engineered Coiled-Coil Protein for Delivery of Inverse Agonist for Osteoarthritis. AB - Osteoarthritis (OA) results from degenerative and abnormal function of joints, with localized biochemistry playing a critical role in its onset and progression. As high levels of all- trans retinoic acid (ATRA) in synovial fluid have been identified as a contributive factor to OA, the synthesis of de novo antagonists for retinoic acid receptors (RARs) has been exploited to interrupt the mechanism of ATRA action. BMS493, a pan-RAR inverse agonist, has been reported as an effective inhibitor of ATRA signaling pathway; however, it is unstable and rapidly degrades under physiological conditions. We employed an engineered cartilage oligomeric matrix protein coiled-coil (CccS) protein for the encapsulation, protection, and delivery of BMS493. In this study, we determine the binding affinity of CccS to BMS493 and the stimulator, ATRA, via competitive binding assay, in which ATRA exhibits approximately 5-fold superior association with CccS than BMS493. Interrogation of the structure of CccS indicates that ATRA causes about 10% loss in helicity, while BMS493 did not impact the structure. Furthermore, CccS self-assembles into nanofibers when bound to BMS493 or ATRA as expected, displaying 11-15 nm in diameter. Treatment of human articular chondrocytes in vitro reveals that CccS.BMS493 demonstrates a marked improvement in efficacy in reducing the mRNA levels of matrix metalloproteinase-13 (MMP-13), one of the main proteases responsible for the degradation of the extracellular cartilage matrix compared to BMS493 alone in the presence of ATRA, interleukin-1 beta (IL-1beta), or IL-1 beta together with ATRA. These results support the feasibility of utilizing coiled-coil proteins as drug delivery vehicles for compounds of relatively limited bioavailability for the potential treatment of OA. PMID- 29601729 TI - Poly(ethylene oxide monomethyl ether)- block-poly(propylene succinate) Nanoparticles: Synthesis and Characterization, Enzymatic and Cellular Degradation, Micellar Solubilization of Paclitaxel, and in Vitro and in Vivo Evaluation. AB - Polyester-based nanostructures are widely studied as drug-delivery systems due to their biocompatibility and biodegradability. They are already used in the clinic. In this work, we describe a new and simple biodegradable and biocompatible system as the Food and Drug Administration approved polyesters (poly-epsilon caprolactone, polylactic acid, and poly(lactic- co-glycolic acid)) for the delivery of the anticancer drug paclitaxel (PTX) as a model drug. A hydrophobic polyester, poly(propylene succinate) (PPS), was prepared from a nontoxic alcohol (propylene glycol) and monomer from the Krebs's cycle (succinic acid) in two steps via esterification and melt polycondensation. Furthermore, their amphiphilic block copolyester, poly(ethylene oxide monomethyl ether)- block poly(propylene succinate) (mPEO- b-PPS), was prepared by three steps via esterification followed by melt polycondensation and the addition of mPEO to the PPS macromolecules. Analysis of the in vitro cellular behavior of the prepared nanoparticle carriers (NPs) (enzymatic degradation, uptake, localization, and fluorescence resonance energy-transfer pair degradation studies) was performed by fluorescence studies. PTX was loaded to the NPs of variable sizes (30, 70, and 150 nm), and their in vitro release was evaluated in different cell models and compared with commercial PTX formulations. The mPEO- b-PPS copolymer analysis displays glass transition temperature < body temperature < melting temperature, lower toxicity (including the toxicity of their degradation products), drug solubilization efficacy, stability against spontaneous hydrolysis during transport in bloodstream, and simultaneous enzymatic degradability after uptake into the cells. The detailed cytotoxicity in vitro and in vivo tumor efficacy studies have shown the superior efficacy of the NPs compared with PTX and PTX commercial formulations. PMID- 29601730 TI - Hu Replies. PMID- 29601731 TI - Nanoscale Rheology and Anisotropic Diffusion Using Single Gold Nanorod Probes. AB - The complex rotational and translational Brownian motion of anisotropic particles depends on their shape and the viscoelasticity of their surroundings. Because of their strong optical scattering and chemical versatility, gold nanorods would seem to provide the ultimate probes of rheology at the nanoscale, but the suitably accurate orientational tracking required to compute rheology has not been demonstrated. Here we image single gold nanorods with a laser-illuminated dark-field microscope and use optical polarization to determine their three dimensional orientation to better than one degree. We convert the rotational diffusion of single nanorods in viscoelastic polyethylene glycol solutions to rheology and obtain excellent agreement with bulk measurements. Extensions of earlier models of anisotropic translational diffusion to three dimensions and viscoelastic fluids give excellent agreement with the observed motion of single nanorods. We find that nanorod tracking provides a uniquely capable approach to microrheology and provides a powerful tool for probing nanoscale dynamics and structure in a range of soft materials. PMID- 29601732 TI - Topological pi Junctions from Crossed Andreev Reflection in the Quantum Hall Regime. AB - We consider a two-dimensional electron gas (2DEG) in the quantum Hall regime in the presence of a Zeeman field, with the Fermi level tuned to a filling factor of nu=1. We show that, in the presence of spin-orbit coupling, contacting the 2DEG with a narrow strip of an s-wave superconductor produces a topological superconducting gap along the contact as a result of crossed Andreev reflection (CAR) processes across the strip. The sign of the topological gap, controlled by the CAR amplitude, depends periodically on the Fermi wavelength and strip width and can be externally tuned. An interface between two halves of a long strip with topological gaps of opposite sign implements a robust pi junction, hosting a pair of Majorana zero modes that do not split despite their overlap. We show that such a configuration can be exploited to perform protected non-Abelian tunnel-braid operations without any fine tuning. PMID- 29601733 TI - Valley Topological Phases in Bilayer Sonic Crystals. AB - Recently, the topological physics in artificial crystals for classical waves has become an emerging research area. In this Letter, we propose a unique bilayer design of sonic crystals that are constructed by two layers of coupled hexagonal array of triangular scatterers. Assisted by the additional layer degree of freedom, a rich topological phase diagram is achieved by simply rotating scatterers in both layers. Under a unified theoretical framework, two kinds of valley-projected topological acoustic insulators are distinguished analytically, i.e., the layer-mixed and layer-polarized topological valley Hall phases, respectively. The theory is evidently confirmed by our numerical and experimental observations of the nontrivial edge states that propagate along the interfaces separating different topological phases. Various applications such as sound communications in integrated devices can be anticipated by the intriguing acoustic edge states enriched by the layer information.

AB - The honeycomb Kitaev-Heisenberg model is a source of a quantum spin liquid with Majorana fermions and gauge flux excitations as fractional quasiparticles. Here we unveil the highly unusual low-temperature heat conductivity kappa of alpha RuCl_{3}, a prime candidate for realizing such physics: beyond a magnetic field of B_{c}~7.5 T, kappa increases by about one order of magnitude, both for in plane as well as out-of-plane transport. This clarifies the unusual magnetic field dependence unambiguously to be the result of severe scattering of phonons off putative Kitaev-Heisenberg excitations in combination with a drastic field induced change of the magnetic excitation spectrum. In particular, an unexpected, large energy gap arises, which increases linearly with the magnetic field, reaching remarkable homega_{0}/k_{B}~50 K at 18 T.

AB - We develop a mathematical framework to analyze electrochemical impedance spectra in terms of a distribution of diffusion times (DDT) for a parallel array of random finite-length Warburg (diffusion) or Gerischer (reaction-diffusion) circuit elements. A robust DDT inversion method is presented based on complex nonlinear least squares regression with Tikhonov regularization and illustrated for three cases of nanostructured electrodes for energy conversion: (i) a carbon nanotube supercapacitor, (ii) a silicon nanowire Li-ion battery, and (iii) a porous-carbon vanadium flow battery. The results demonstrate the feasibility of nondestructive "impedance imaging" to infer microstructural statistics of random, heterogeneous materials. PMID- 29601736 TI - Nonresonant Local Fields Enhance Second-Harmonic Generation from Metal Nanoislands with Dielectric Cover. AB - We study second-harmonic generation from gold nanoislands covered with amorphous titanium oxide (TiO_{2}) films. As the TiO_{2} thickness increases, the plasmon resonance of the nanoislands shifts away from the second-harmonic wavelength of 532 nm, diminishing the resonant enhancement of the process at this wavelength. Nevertheless, the second-harmonic signal is enhanced by up to a factor of 45 with increasing TiO_{2} thickness. This unexpected effect arises from the scaling of local fields at the fundamental wavelength of 1064 nm-which is at the far tail of the resonance-due to a change in the dielectric environment of the nanoislands. PMID- 29601737 TI - Alignment and Imaging of the CS_{2} Dimer Inside Helium Nanodroplets. AB - The carbon disulphide (CS_{2}) dimer is formed inside He nanodroplets and identified using fs laser-induced Coulomb explosion, by observing the CS_{2}^{+} ion recoil velocity. It is then shown that a 160 ps moderately intense laser pulse can align the dimer in advantageous spatial orientations which allow us to determine the cross-shaped structure of the dimer by analysis of the correlations between the emission angles of the nascent CS_{2}^{+} and S^{+} ions, following the explosion process. Our method will enable fs time-resolved structural imaging of weakly bound molecular complexes during conformational isomerization, including formation of exciplexes.

AB - In the large-momentum effective field theory approach to parton physics, the matrix elements of nonlocal operators of quark and gluon fields, linked by straight Wilson lines in a spatial direction, are calculated in lattice quantum chromodynamics as a function of hadron momentum. Using the heavy-quark effective theory formalism, we show a multiplicative renormalization of these operators at all orders in perturbation theory, both in dimensional and lattice regularizations. The result provides a theoretical basis for extracting parton properties through properly renormalized observables in Monte Carlo simulations.

AB - The direct single-ionization cross section for Ar by positron impact has been measured in the region above the first ionization threshold. These measurements are compared to semiclassical calculations which give rise to a power law variation of the cross section in the threshold region. The experimental results appear to be in disagreement with extensions to the Wannier theory applied to positron impact ionization, with a smaller exponent than that calculated by most previous works. In fact, in this work, we see no difference in threshold behavior between the positron and electron cases. Possible reasons for this discrepancy are discussed.

Using a combination of camera-rate and pump-probe cryo-Lorentz transmission electron microscopy, we directly resolve the spatiotemporal evolution of the magnetization ensuing optical excitation. The Skyrmion lattice was found to maintain its structural properties during the laser-induced demagnetization, and its recovery to the initial state happened in the sub-MUs to MUs range, depending on the cooling rate of the system. PMID- 29601741 TI - Origin of Negative Capacitance in Bipolar Organic Diodes. AB - Negative differential capacitance (NC) occurring at low frequencies in organic light-emitting diodes (OLEDs) is a poorly understood phenomenon. We study the origin of the NC effect by systematically varying the number of electron traps in OLEDs based on the polymeric semiconductor poly(p-phenylene vinylene). Increasing the electron trap density enhances the NC effect. The magnitude and observed decrease of the relaxation time is consistent with the (inverse) rate of trap assisted recombination. The absence of NC in a nearly trap-free light-emitting diode unambiguously shows that trap-assisted recombination is the responsible mechanism for the negative contribution to the capacitance in bipolar organic diodes. Our results reveal that the NC effect can be exploited to quantitatively determine the number of traps in organic semiconductors in a nondestructive fashion. PMID- 29601742 TI - Duality in Power-Law Localization in Disordered One-Dimensional Systems. AB - The transport of excitations between pinned particles in many physical systems may be mapped to single-particle models with power-law hopping, 1/r^{a}. For randomly spaced particles, these models present an effective peculiar disorder that leads to surprising localization properties. We show that in one-dimensional systems almost all eigenstates (except for a few states close to the ground state) are power-law localized for any value of a>0. Moreover, we show that our model is an example of a new universality class of models with power-law hopping, characterized by a duality between systems with long-range hops (a<1) and short range hops (a>1), in which the wave function amplitude falls off algebraically with the same power gamma from the localization center.

AB - Using exact quantum Monte Carlo calculations, we examine the interplay between localization of electronic states driven by many-body correlations and that by randomness in a two-dimensional system featuring linearly vanishing density of states at the Fermi level. A novel disorder-induced nonmagnetic insulating phase is found to emerge from the zero-temperature quantum critical point separating a semimetal and a Mott insulator. Within this phase, a phase transition from a gapless Anderson-like insulator to a gapped Mott-like insulator is identified. Implications of the phase diagram are also discussed. PMID- 29601745 TI - High-Power Collective Charging of a Solid-State Quantum Battery. AB - Quantum information theorems state that it is possible to exploit collective quantum resources to greatly enhance the charging power of quantum batteries (QBs) made of many identical elementary units. We here present and solve a model of a QB that can be engineered in solid-state architectures. It consists of N two level systems coupled to a single photonic mode in a cavity. We contrast this collective model ("Dicke QB"), whereby entanglement is genuinely created by the common photonic mode, to the one in which each two-level system is coupled to its own separate cavity mode ("Rabi QB"). By employing exact diagonalization, we demonstrate the emergence of a quantum advantage in the charging power of Dicke QBs, which scales like sqrt[N] for N?1.

AB - We use large scale quantum Monte Carlo simulations to study an extended Hubbard model of hard core bosons on the kagome lattice. In the limit of strong nearest neighbor interactions at 1/3 filling, the interplay between frustration and quantum fluctuations leads to a valence bond solid ground state. The system undergoes a quantum phase transition to a superfluid phase as the interaction strength is decreased. It is still under debate whether the transition is weakly first order or represents an unconventional continuous phase transition. We present a theory in terms of an easy plane noncompact CP^{1} gauge theory describing the phase transition at 1/3 filling. Utilizing large scale quantum Monte Carlo simulations with parallel tempering in the canonical ensemble up to 15552 spins, we provide evidence that the phase transition is continuous at exactly 1/3 filling. A careful finite size scaling analysis reveals an unconventional scaling behavior hinting at deconfined quantum criticality.

AB - We use finite-temperature density functional theory coupled to classical molecular dynamics simulation to calculate the miscibility gap of hydrogen-helium mixtures. The van der Waals density functional (vdW-DF) theory is used, which leads to lower demixing temperatures compared to computations using the Perdew Burke-Ernzerhof functional. Our calculations suggest that current Jupiter models are most likely too hot to allow demixing in the interior. A Jupiter isentrope based on our vdW-DF data is presented. Our demixing phase diagram still predicts phase separation in Saturn, but in a significantly reduced fraction of its volume. PMID- 29601748 TI - Three Phase-Grating Moire Neutron Interferometer for Large Interferometer Area Applications. AB - We demonstrate a three phase-grating moire neutron interferometer in a highly intense neutron beam as a robust candidate for large area interferometry applications and for the characterization of materials. This novel far-field moire technique allows for broad wavelength acceptance and relaxed requirements related to fabrication and alignment, thus circumventing the main obstacles associated with perfect crystal neutron interferometry. We observed interference fringes with an interferometer length of 4 m and examined the effects of an aluminum 6061 alloy sample on the coherence of the system. Experiments to measure the autocorrelation length of samples and the universal gravitational constant are proposed and discussed. PMID- 29601749 TI - Prediction of a Large-Gap and Switchable Kane-Mele Quantum Spin Hall Insulator. AB - Fundamental research and technological applications of topological insulators are hindered by the rarity of materials exhibiting a robust topologically nontrivial phase, especially in two dimensions. Here, by means of extensive first-principles calculations, we propose a novel quantum spin Hall insulator with a sizable band gap of ~0.5 eV that is a monolayer of jacutingaite, a naturally occurring layered mineral first discovered in 2008 in Brazil and recently synthesized. This system realizes the paradigmatic Kane-Mele model for quantum spin Hall insulators in a potentially exfoliable two-dimensional monolayer, with helical edge states that are robust and that can be manipulated exploiting a unique strong interplay between spin-orbit coupling, crystal-symmetry breaking, and dielectric response. PMID- 29601750 TI - Resolving Point Defects in the Hydration Structure of Calcite (10.4) with Three Dimensional Atomic Force Microscopy. AB - It seems natural to assume that defects at mineral surfaces critically influence interfacial processes such as the dissolution and growth of minerals in water. The experimental verification of this claim, however, is challenging and requires real-space methods with utmost spatial resolution, such as atomic force microscopy (AFM). While defects at mineral-water interfaces have been resolved in 2D AFM images before, the perturbation of the surrounding hydration structure has not yet been analyzed experimentally. In this Letter, we demonstrate that point defects on the most stable and naturally abundant calcite (10.4) surface can be resolved using high-resolution 3D AFM-even within the fifth hydration layer. Our analysis of the hydration structure surrounding the point defect shows a perturbation of the hydration with a lateral extent of approximately one unit cell. These experimental results are corroborated by molecular dynamics simulations. PMID- 29601752 TI - Janus and Huygens Dipoles: Near-Field Directionality Beyond Spin-Momentum Locking. AB - Unidirectional scattering from circularly polarized dipoles has been demonstrated in near-field optics, where the quantum spin-Hall effect of light translates into spin-momentum locking. By considering the whole electromagnetic field, instead of its spin component alone, near-field directionality can be achieved beyond spin momentum locking. This unveils the existence of the Janus dipole, with side dependent topologically protected coupling to waveguides, and reveals the near field directionality of Huygens dipoles, generalizing Kerker's condition. Circular dipoles, together with Huygens and Janus sources, form the complete set of all possible directional dipolar sources in the far- and near-field. This allows the designing of directional emission, scattering, and waveguiding, fundamental for quantum optical technology, integrated nanophotonics, and new metasurface designs. PMID- 29601753 TI - Direct Measurement of Lateral Correlations under Controlled Nanoconfinement. AB - Lateral correlations along hydrophobic surfaces whose separation can be varied continuously are measured by x-ray scattering using a modified surface force apparatus coupled with synchrotron radiation, named SFAX. A weak isotropic diffuse scattering along the equatorial plane is revealed for mica surfaces rendered hydrophobic and charge neutral by immersion in cationic surfactant solutions at low concentrations. The peak corresponds to a lateral surface correlation length xi~12 nm, without long-range order. These findings are compatible with the atomic force microscopy imaging of a single surface, where adsorbed surfactant stripes appear surrounded by bare mica zones. Remarkably, the scattering patterns remain stable for gap widths D larger than the lateral period but change in intensity and shape (to a lesser extent) as soon as Dh^{*}->ZZ, the dominant momentum dependent part of the one-loop scalar singlet corrections, especially above the new threshold at 2m_{S}, leads to a measurable deviation in the differential distribution of the Z-pair invariant mass, in accordance with the quadratic divergence cancellation to the Higgs mass. We find that it is conceivable to probe such new physics at the 5sigma level at the high-luminosity LHC, improving further with the upgraded 27 TeV LHC, without requiring the precise measurement of the Higgs boson total width. The discovery of such a Higgs portal could also have important implications for thermal dark matter as well as for electroweak baryogenesis. PMID- 29601756 TI - Photon Subtraction by Many-Body Decoherence. AB - We experimentally and theoretically investigate the scattering of a photonic quantum field from another stored in a strongly interacting atomic Rydberg ensemble. Considering the many-body limit of this problem, we derive an exact solution to the scattering-induced spatial decoherence of multiple stored photons, allowing for a rigorous understanding of the underlying dissipative quantum dynamics. Combined with our experiments, this analysis reveals a correlated coherence-protection process in which the scattering from one excitation can shield all others from spatial decoherence. We discuss how this effect can be used to manipulate light at the quantum level, providing a robust mechanism for single-photon subtraction, and experimentally demonstrate this capability. PMID- 29601757 TI - Avalanches and Criticality in Driven Magnetic Skyrmions. AB - We show using numerical simulations that slowly driven Skyrmions interacting with random pinning move via correlated jumps or avalanches. The avalanches exhibit power-law distributions in their duration and size, and the average avalanche shape for different avalanche durations can be scaled to a universal function, in agreement with theoretical predictions for systems in a nonequilibrium critical state. A distinctive feature of Skyrmions is the influence of the nondissipative Magnus term. When we increase the ratio of the Magnus term to the damping term, a change in the universality class of the behavior occurs, the average avalanche shape becomes increasingly asymmetric, and individual avalanches exhibit motion in the direction perpendicular to their own density gradient. PMID- 29601758 TI - Quantum Simulation of Electronic Structure with Linear Depth and Connectivity. AB - As physical implementations of quantum architectures emerge, it is increasingly important to consider the cost of algorithms for practical connectivities between qubits. We show that by using an arrangement of gates that we term the fermionic swap network, we can simulate a Trotter step of the electronic structure Hamiltonian in exactly N depth and with N^{2}/2 two-qubit entangling gates, and prepare arbitrary Slater determinants in at most N/2 depth, all assuming only a minimal, linearly connected architecture. We conjecture that no explicit Trotter step of the electronic structure Hamiltonian is possible with fewer entangling gates, even with arbitrary connectivities. These results represent significant practical improvements on the cost of most Trotter-based algorithms for both variational and phase-estimation-based simulation of quantum chemistry. PMID- 29601759 TI - Kinetic Theory of Electronic Transport in Random Magnetic Fields. AB - We present the theory of quasiparticle transport in perturbatively small inhomogeneous magnetic fields across the ballistic-to-hydrodynamic crossover. In the hydrodynamic limit, the resistivity rho generically grows proportionally to the rate of momentum-conserving electron-electron collisions at large enough temperatures T. In particular, the resulting flow of electrons provides a simple scenario where viscous effects suppress conductance below the ballistic value. This new mechanism for rho?T^{2} resistivity in a Fermi liquid may describe low T transport in single-band SrTiO_{3}. PMID- 29601760 TI - Accurate Mapping of Multilevel Rydberg Atoms on Interacting Spin-1/2 Particles for the Quantum Simulation of Ising Models. AB - We study a system of atoms that are laser driven to nD_{3/2} Rydberg states and assess how accurately they can be mapped onto spin-1/2 particles for the quantum simulation of anisotropic Ising magnets. Using nonperturbative calculations of the pair potentials between two atoms in the presence of electric and magnetic fields, we emphasize the importance of a careful selection of experimental parameters in order to maintain the Rydberg blockade and avoid excitation of unwanted Rydberg states. We benchmark these theoretical observations against experiments using two atoms. Finally, we show that in these conditions, the experimental dynamics observed after a quench is in good agreement with numerical simulations of spin-1/2 Ising models in systems with up to 49 spins, for which numerical simulations become intractable. PMID- 29601761 TI - Visibility-Based Hypothesis Testing Using Higher-Order Optical Interference. AB - Many quantum information protocols rely on optical interference to compare data sets with efficiency or security unattainable by classical means. Standard implementations exploit first-order coherence between signals whose preparation requires a shared phase reference. Here, we analyze and experimentally demonstrate the binary discrimination of visibility hypotheses based on higher order interference for optical signals with a random relative phase. This provides a robust protocol implementation primitive when a phase lock is unavailable or impractical. With the primitive cost quantified by the total detected optical energy, optimal operation is typically reached in the few-photon regime. PMID- 29601762 TI - Macroscopically Degenerate Exactly Solvable Point in the Spin-1/2 Kagome Quantum Antiferromagnet. AB - Frustrated quantum magnets are a central theme in condensed matter physics due to the richness of their phase diagrams. They support a panoply of phases including various ordered states and topological phases. Yet, this problem has defied a solution for a long time due to the lack of controlled approximations which make it difficult to distinguish between competing phases. Here we report the discovery of a special quantum macroscopically degenerate point in the XXZ model on the spin-1/2 kagome quantum antiferromagnet for the ratio of Ising to antiferromagnetic transverse coupling J_{z}/J=-1/2. This point is proximate to many competing phases explaining the source of the complexity of the phase diagram. We identify five phases near this point including both spin-liquid and broken-symmetry phases and give evidence that the kagome Heisenberg antiferromagnet is close to a transition between two phases. PMID- 29601763 TI - Switching a Perpendicular Ferromagnetic Layer by Competing Spin Currents. AB - An ultimate goal of spintronics is to control magnetism via electrical means. One promising way is to utilize a current-induced spin-orbit torque (SOT) originating from the strong spin-orbit coupling in heavy metals and their interfaces to switch a single perpendicularly magnetized ferromagnetic layer at room temperature. However, experimental realization of SOT switching to date requires an additional in-plane magnetic field, or other more complex measures, thus severely limiting its prospects. Here we present a novel structure consisting of two heavy metals that delivers competing spin currents of opposite spin indices. Instead of just canceling the pure spin current and the associated SOTs as one expects and corroborated by the widely accepted SOTs, such devices manifest the ability to switch the perpendicular CoFeB magnetization solely with an in-plane current without any magnetic field. Magnetic domain imaging reveals selective asymmetrical domain wall motion under a current. Our discovery not only paves the way for the application of SOT in nonvolatile technologies, but also poses questions on the underlying mechanism of the commonly believed SOT-induced switching phenomenon. PMID- 29601764 TI - Possible Many-Body Localization in a Long-Lived Finite-Temperature Ultracold Quasineutral Molecular Plasma. AB - We argue that the quenched ultracold plasma presents an experimental platform for studying the quantum many-body physics of disordered systems in the long-time and finite energy-density limits. We consider an experiment that quenches a plasma of nitric oxide to an ultracold system of Rydberg molecules, ions, and electrons that exhibits a long-lived state of arrested relaxation. The qualitative features of this state fail to conform with classical models. Here, we develop a microscopic quantum description for the arrested phase based on an effective many body spin Hamiltonian that includes both dipole-dipole and van der Waals interactions. This effective model appears to offer a way to envision the essential quantum disordered nonequilibrium physics of this system. PMID- 29601765 TI - Edge-Mode Lasing in 1D Topological Active Arrays. AB - We report the first observation of lasing topological edge states in a 1D Su Schrieffer-Heeger active array of microring resonators. We show that the judicious use of non-Hermiticity can promote single edge-mode lasing in such arrays. Our experimental and theoretical results demonstrate that, in the presence of chiral-time symmetry, this non-Hermitian topological structure can experience phase transitions that are dictated by a complex geometric phase. Our work may pave the way towards understanding the fundamental aspects associated with the interplay among non-Hermiticity, nonlinearity, and topology in active systems. PMID- 29601766 TI - On-Demand Generation of Neutral and Negatively Charged Silicon-Vacancy Centers in Diamond. AB - Point defects in wide-band-gap semiconductors are emerging as versatile resources for nanoscale sensing and quantum information science, but our understanding of the photoionization dynamics is presently incomplete. Here, we use two-color confocal microscopy to investigate the dynamics of charge in type 1b diamond hosting nitrogen-vacancy (NV) and silicon-vacancy (SiV) centers. By examining the nonlocal fluorescence patterns emerging from local laser excitation, we show that, in the simultaneous presence of photogenerated electrons and holes, SiV (NV) centers selectively transform into the negative (neutral) charge state. Unlike NVs, 532 nm illumination ionizes SiV^{-} via a single-photon process, thus hinting at a comparatively shallower ground state. In particular, slower ionization rates at longer wavelengths suggest the latter lies approximately ~1.9 eV below the conduction band minimum. Building on the above observations, we demonstrate on-demand SiV and NV charge initialization over large areas via green laser illumination of variable intensity. PMID- 29601767 TI - Demonstration of Cascaded Modulator-Chicane Microbunching of a Relativistic Electron Beam. AB - We present results of an experiment showing the first successful demonstration of a cascaded microbunching scheme. Two modulator-chicane prebunchers arranged in series and a high power mid-IR laser seed are used to modulate a 52 MeV electron beam into a train of sharp microbunches phase locked to the external drive laser. This configuration is shown to greatly improve matching of the beam into the small longitudinal phase space acceptance of short-wavelength accelerators. We demonstrate trapping of nearly all (96%) of the electrons in a strongly tapered inverse free-electron laser accelerator, with an order-of-magnitude reduction in injection losses compared to the classical single-buncher scheme. These results represent a critical advance in laser-based longitudinal phase space manipulations and find application in high gradient advanced acceleration as well as in high peak and average power coherent radiation sources. PMID- 29601768 TI - Unusual Crystallization Behavior Close to the Glass Transition. AB - Using molecular simulations, we shed light on the mechanism underlying crystal nucleation in metal alloys and unravel the interplay between crystal nucleation and glass transition, as the conditions of crystallization lie close to this transition. While decreasing the temperature of crystallization usually results in a lower free energy barrier, we find an unexpected reversal of behavior for glass-forming alloys as the temperature of crystallization approaches the glass transition. For this purpose, we simulate the crystallization process in two glass-forming Copper alloys, Ag_{6}Cu_{4}, which has a positive heat of mixing, and CuZr, characterized by a large negative heat of mixing. Our results allow us to identify this unusual behavior as directly correlated with a nonmonotonic temperature dependence for the formation energy of connected icosahedral structures, which are incompatible with crystalline order and impede the development of the crystal nucleus, leading to an unexpectedly larger free energy barrier at low temperature. This, in turn, promotes the formation of a predominantly closed-packed critical nucleus, with fewer defects, thereby suggesting a new way to control the structure of the crystal nucleus, which is of key importance in catalysis. PMID- 29601769 TI - Acoustic Purcell Effect for Enhanced Emission. AB - We observe that our experimentally measured emission power enhancement of a speaker inside a previously proposed metacavity agrees with our numerically calculated enhancement of the density of states (DOS) of the source-cavity system. We interpret the agreement by formulating a relation between the emitted sound power and the acoustic DOS. The formulation is an analog to Fermi's golden rule in quantum emission. The formulation complements the radiation impedance theory in traditional acoustics for describing sound emission. Our study bridges the gap between acoustic DOS and the acoustic Purcell effect for sound emission enhancement. PMID- 29601770 TI - Charge Order and Superconductivity in Underdoped YBa_{2}Cu_{3}O_{7-delta} under Pressure. AB - In underdoped cuprates, an incommensurate charge density wave (CDW) order is known to coexist with superconductivity. A dip in T_{c} at the hole doping level where the CDW is strongest (n_{p}?0.12) suggests that CDW order may suppress superconductivity. We investigate the interplay of charge order with superconductivity in underdoped YBa_{2}Cu_{3}O_{7-delta} by measuring the temperature dependence of the Hall coefficient R_{H}(T) at high magnetic field and at high hydrostatic pressure. We find that, although pressure increases T_{c} by up to 10 K at 2.6 GPa, it has very little effect on R_{H}(T). This suggests that pressure, at these levels, only weakly affects the CDW and that the increase in T_{c} with pressure cannot be attributed to a suppression of the CDW. We argue, therefore, that the dip in T_{c} at n_{p}?0.12 at ambient pressure is probably not caused by the CDW formation.

AB - We investigate the terahertz (THz)-pulse-driven nonlinear response in the d-wave cuprate superconductor Bi_{2}Sr_{2}CaCu_{2}O_{8+x} (Bi2212) using a THz pump near infrared probe scheme in the time domain. We observe an oscillatory behavior of the optical reflectivity that follows the THz electric field squared and is markedly enhanced below T_{c}. The corresponding third-order nonlinear effect exhibits both A_{1g} and B_{1g} symmetry components, which are decomposed from polarization-resolved measurements. A comparison with a BCS calculation of the nonlinear susceptibility indicates that the A_{1g} component is associated with the Higgs mode of the d-wave order parameter. PMID- 29601773 TI - Strongly gamma-Deformed N=4 Supersymmetric Yang-Mills Theory as an Integrable Conformal Field Theory. AB - We demonstrate by explicit multiloop calculation that gamma-deformed planar N=4 supersymmetric Yang-Mills (SYM) theory, supplemented with a set of double-trace counterterms, has two nontrivial fixed points in the recently proposed double scaling limit, combining vanishing 't Hooft coupling and large imaginary deformation parameter. We provide evidence that, at the fixed points, the theory is described by an integrable nonunitary four-dimensional conformal field theory. We find a closed expression for the four-point correlation function of the simplest protected operators and use it to compute the exact conformal data of operators with arbitrary Lorentz spin. We conjecture that both conformal symmetry and integrability should survive in gamma-deformed planar N=4 SYM theory for arbitrary values of the deformation parameters. PMID- 29601774 TI - Gravitational-Wave Luminosity of Binary Neutron Stars Mergers. AB - We study the gravitational-wave peak luminosity and radiated energy of quasicircular neutron star mergers using a large sample of numerical relativity simulations with different binary parameters and input physics. The peak luminosity for all the binaries can be described in terms of the mass ratio and of the leading-order post-Newtonian tidal parameter solely. The mergers resulting in a prompt collapse to black hole have the largest peak luminosities. However, the largest amount of energy per unit mass is radiated by mergers that produce a hypermassive neutron star or a massive neutron star remnant. We quantify the gravitational-wave luminosity of binary neutron star merger events, and set upper limits on the radiated energy and the remnant angular momentum from these events. We find that there is an empirical universal relation connecting the total gravitational radiation and the angular momentum of the remnant. Our results constrain the final spin of the remnant black hole and also indicate that stable neutron star remnant forms with super-Keplerian angular momentum. PMID- 29601775 TI - Directional Dicke Subradiance with Nonclassical and Classical Light Sources. AB - We investigate Dicke subradiance of N>=2 distant quantum sources in free space, i.e., the spatial emission patterns of spontaneously radiating noninteracting multilevel atoms or multiphoton sources, prepared in totally antisymmetric states. We find that the radiated intensity is marked by a full suppression of spontaneous emission in particular directions. In resemblance to the analogous, yet inverted, superradiant emission profiles of N distant two-level atoms prepared in symmetric Dicke states, we call the corresponding emission patterns directional Dicke subradiance. We further derive that higher-order intensity correlations of the light emitted by statistically independent thermal light sources display the same directional Dicke subradiant behavior and show that it stems from the same interference phenomenon as in the case of quantum sources. We finally present measurements of directional Dicke subradiance for N=2,...,5 distant thermal light sources corroborating the theoretical findings. PMID- 29601776 TI - Directional Sensitivity in Light-Mass Dark Matter Searches with Single-Electron Resolution Ionization Detectors. AB - We propose a method using solid state detectors with directional sensitivity to dark matter interactions to detect low-mass weakly interacting massive particles (WIMPs) originating from galactic sources. In spite of a large body of literature for high-mass WIMP detectors with directional sensitivity, no available technique exists to cover WIMPs in the mass range <1 GeV/c^{2}. We argue that single electron-resolution semiconductor detectors allow for directional sensitivity once properly calibrated. We examine the commonly used semiconductor material response to these low-mass WIMP interactions. PMID- 29601777 TI - A comparison of manual counting of rabbit reticulocytes with ADVIA 2120i analyzer counting. AB - We compared manual counting of reticulocytes in rabbits with automatic counting using an ADVIA 2120i analyzer. Reproducibility and the influence of different anticoagulants (EDTA and Li-heparin) were also examined. Blood samples of 331 rabbits (method comparison, n = 289; reproducibility, n = 33; comparison of anticoagulants, n = 9) were tested. The reticulocyte numbers of each specimen were manually determined twice for method comparison. Passing-Bablok regressions, Bland-Altman plots, and the coefficient of variation (CV) were used to evaluate statistical significance. Good correlation (rs = 0.81) was observed between manual reticulocyte counting (groups 1-4) and the ADVIA 2120i. Quantification with the ADVIA 2120i was reproducible for relative reticulocyte numbers (EDTA, CV = 4.24%; Li-heparin, CV = 3.63%) and absolute reticulocyte numbers (EDTA, CV = 5.64%; Li-heparin, CV = 3.81%). The absolute and relative reticulocyte numbers were significantly higher in Li-heparin samples than in EDTA samples (absolute, p = 0.009; relative, p = 0.016). The ADVIA 2120i is suitable for counting reticulocytes in rabbit blood samples, but reticulocyte numbers are higher by manual counting than by ADVIA 2120i counting. Therefore, microscopic confirmation of quantifications is recommended when high numbers of reticulocytes are observed. The anticoagulant of choice is EDTA. PMID- 29601778 TI - Frequency of Equus caballus papillomavirus in equine aural plaques. AB - Despite the reported association between aural plaques and the presence of Equus caballus papillomavirus (EcPV), there are few data regarding the distribution of viral types in different geographic regions or possible correlations for different papillomaviruses and lesion characteristics. We detected the presence and frequency of EcPV (1-7) DNA in aural plaque biopsies of horses from different regions of Brazil and identified the patterns of these infections or coinfections and their possible association with lesion severity. A total of 108 aural plaque biopsies from horses in the 5 geopolitical regions of Brazil were examined. We performed PCR to detect EcPV DNA in the biopsies. At least 1 type of EcPV was detected in 97% of the samples. EcPV coinfection was observed in 59% of the samples. Compared to the other viruses, EcPV-4 was found at the highest frequency in coinfection (84%) or individually identified (32%). EcPV-2 and -7 were not detected. No significant association was found between lesion characteristics (type and distribution) and either the viral type detected or the presence of coinfection. EcPV is widely distributed in Brazil, both isolated and in coinfection; the viral type does not appear to influence the clinical characteristics of equine aural plaques. PMID- 29601779 TI - Blastomyces dermatitidis pneumonia in a llama. AB - A 20-y-old female llama ( Lama glama) was euthanized after a history of chronic dyspnea and osteoarthritis. At autopsy, the lungs were covered by clear gelatinous material and expanded by firm, variably discrete, tan-white nodules up to 8 cm diameter containing tan-white, viscous material. The tracheobronchial lymph nodes were firm and enlarged up to 6 * 4 * 3 cm; the thoracic aorta and carotid arteries were lined by hard, tan-white, mineralized intimal plaques. Histologic examination of lung revealed numerous 10-20 MUm diameter yeasts with clear 1-2 MUm thick double-contoured walls, central basophilic nuclei, and frequent broad-based budding, consistent with Blastomyces dermatitidis. DNA sequencing confirmed the diagnosis. B. dermatitidis should be considered in the differential diagnosis of pulmonary disease in llamas.

AB - A real-time PCR assay for the leukotoxin gene of Bibersteinia trehalosi was developed and validated to better identify this pathogen, which is a cause of respiratory disease in bighorn sheep. The specificity of the PCR primers was evaluated with DNA from 59 known isolates of the Pasteurellaceae family. For validation, 162 field samples were compared using both the new assay and an indirect method using 2 sets of published protocols. The real-time PCR assay was found to be specific for the leukotoxin gene of B. trehalosi and provides a rapid and direct approach for detecting leukotoxin-producing forms of this organism from samples containing mixed species of leukotoxin-positive Pasteurellaceae. PMID- 29601781 TI - Cardiac fibroblast-specific p38alpha MAP kinase promotes cardiac hypertrophy via a putative paracrine interleukin-6 signaling mechanism. AB - Recent studies suggest that cardiac fibroblast-specific p38alpha MAPK contributes to the development of cardiac hypertrophy, but the underlying mechanism is unknown. Our study used a novel fibroblast-specific, tamoxifen-inducible p38alpha knockout (KO) mouse line to characterize the role of fibroblast p38alpha in modulating cardiac hypertrophy, and we elucidated the mechanism. Myocardial injury was induced in tamoxifen-treated Cre-positive p38alpha KO mice or control littermates via chronic infusion of the beta-adrenergic receptor agonist isoproterenol. Cardiac function was assessed by pressure-volume conductance catheter analysis and was evaluated for cardiac hypertrophy at tissue, cellular, and molecular levels. Isoproterenol infusion in control mice promoted overt cardiac hypertrophy and dysfunction (reduced ejection fraction, increased end systolic volume, increased cardiac weight index, increased cardiomyocyte area, increased fibrosis, and up-regulation of myocyte fetal genes and hypertrophy associated microRNAs). Fibroblast-specific p38alpha KO mice exhibited marked protection against myocardial injury, with isoproterenol-induced alterations in cardiac function, histology, and molecular markers all being attenuated. In vitro mechanistic studies determined that cardiac fibroblasts responded to damaged myocardium by secreting several paracrine factors known to induce cardiomyocyte hypertrophy, including IL-6, whose secretion was dependent upon p38alpha activity. In conclusion, cardiac fibroblast p38alpha contributes to cardiomyocyte hypertrophy and cardiac dysfunction, potentially via a mechanism involving paracrine fibroblast-to-myocyte IL-6 signaling.-Bageghni, S. A., Hemmings, K. E., Zava, N., Denton, C. P., Porter, K. E., Ainscough, J. F. X., Drinkhill, M. J., Turner, N. A.

PMID- 29601782 TI - Hepatic PHD2/HIF-1alpha axis is involved in postexercise systemic energy homeostasis. AB - Exercise plays an important role in the prevention and treatment of chronic liver disease and associated metabolic disorders. A single bout of exercise induces tissue blood flow redistribution, which decreases splanchnic circulation and leads to physiologic hypoxia in the gastrointestinal system and liver. The transcription factor, hypoxia inducible factor-1alpha (HIF-1alpha), and its regulator, prolylhydroxylase 2 (PHD2), play pivotal roles in the response to oxygen flux by regulating downstream gene expression levels in the liver. We hypothesized that exercise increases the HIF-1alpha levels in the liver, and that the hepatic PHD2/HIF-1alpha axis is involved in postexercise restoration of systemic energy homeostasis. Through constant O2 consumption, CO2 production, food and water intake, and physical activity detection with metabolic chambers, we observed that one 30-min session of swimming exercise enhances systemic energy metabolism in mice. By using the noninvasive bioluminescence imaging ROSA26 oxygen-dependent domain Luc mouse model, we reveal that exercise increases in vivo HIFalpha levels in the liver. Intraperitoneal injections of the PHD inhibitor, dimethyloxalylglycine, mimicked exercise-induced HIFalpha increase, whereas the HIF-1alpha inhibitor, PX-478, blocked this effect. We next constructed liver-specific knockout (LKO) mouse models with albumin- Cre mediated, hepatocyte-specific Hif1a and Phd2 deletion. Compared with their controls, Hif1a-LKO and Phd2-LKO mice exhibited distinct patterns of hepatic metabolism-related gene expression profiles. Moreover, Hif1a-LKO mice failed to restore systemic energy homeostasis after exercise. In conclusion, the current study demonstrates that a single bout of exercise disrupts systemic energy homeostasis, increasing the HIF-1alpha levels in the liver. These findings also provide evidence that the hepatic PHD2/HIF-1alpha axis is involved in postexercise systemic metabolic homeostasis.-Luo, B., Xiang, D., Wu, D., Liu, C., Fang, Y., Chen, P., Hu, Y.-P.

AB - Huntingtin (HTT) fragments with extended polyglutamine tracts self-assemble into amyloid-like fibrillar aggregates. Elucidating the fibril formation mechanism is critical for understanding Huntington's disease pathology and for developing novel therapeutic strategies. Here, we performed systematic experimental and theoretical studies to examine the self-assembly of an aggregation-prone N terminal HTT exon-1 fragment with 49 glutamines (Ex1Q49). Using high-resolution imaging techniques such as electron microscopy and atomic force microscopy, we show that Ex1Q49 fragments in cell-free assays spontaneously convert into large, highly complex bundles of amyloid fibrils with multiple ends and fibril branching points. Furthermore, we present experimental evidence that two nucleation mechanisms control spontaneous Ex1Q49 fibrillogenesis: (1) a relatively slow primary fibril-independent nucleation process, which involves the spontaneous formation of aggregation-competent fibrillary structures, and (2) a fast secondary fibril-dependent nucleation process, which involves nucleated branching and promotes the rapid assembly of highly complex fibril bundles with multiple ends. The proposed aggregation mechanism is supported by studies with the small molecule O4, which perturbs early events in the aggregation cascade and delays Ex1Q49 fibril assembly, comprehensive mathematical and computational modeling studies, and seeding experiments with small, preformed fibrillar Ex1Q49 aggregates that promote the assembly of amyloid fibrils. Together, our results suggest that nucleated branching in vitro plays a critical role in the formation of complex fibrillar HTT exon-1 aggregates with multiple ends.

Localized amyloidosis in the parotid gland is extremely rare. We present a case of localized light chain amyloidosis of the parotid gland without systemic involvement. A 70-year-old woman presented with an asymptomatic swelling of the right parotid region. The findings of a physical examination, hematologic and biochemical investigations, imaging, and cytology were inconclusive. The patient underwent an extracapsular dissection of the right parotid gland. Histologic analysis showed that the tissue of the right parotid gland mostly consisted of amyloid deposition. The amyloid stained with antibodies to lambda light chains. Additional investigations showed no systemic involvement. The patient is asymptomatic 5 months after surgery. Clinicians should be aware of the possibility of localized amyloid light chain amyloidosis in the parotid gland, especially if magnetic resonance imaging, computed tomography imaging, and ultrasound findings are inconclusive, and they should recognize, evaluate, and treat it accordingly.

AB - PURPOSE: To compare the healing potential of platelet-rich fibrin (PRF) and collagen membranes in oral mucosal healing. MATERIALS AND METHODS: Thirty patients with oral premalignant lesions were randomly included in the study and divided in groups A and B. After excising the lesions under local anesthesia, patients in groups A and B underwent grafting with the PRF membrane and the collagen membrane, respectively. Patients were evaluated at postoperative days 7, 15, 30, and 60 for pain, healing, and complications, such as recurrence, fibrosis, scar hypertrophy, and loss of vestibular depth. RESULTS: In group A, 66.66% of patients reported substantially less pain postoperatively at 15-day follow-up than those in group B. At 30-day follow-up, 86.66% of patients in group A reported no pain versus 60% in group B. Pain scores were similar at 7- and 60 day follow-ups. Healing was accelerated in group A at 15- and 30-day follow-ups, but was the same on day 60. Complications, such as fibrosis, loss of vestibular depth, and scar hypertrophy, were seen in group B. Recurrence was seen in 1 patient in group A at 60-day follow-up. CONCLUSION: PRF proved superior to collagen membrane for grafting of oral mucosal surgical defects. However, further study with larger samples is required to prove its efficacy.

AB - INTRODUCTION: Apolipoprotein E (APOE) epsilon4 is the major genetic risk factor for Alzheimer's disease (AD), but its prevalence is unclear because earlier studies did not require biomarker evidence of amyloid beta (Abeta) pathology. METHODS: We included 3451 Abeta+ subjects (853 AD-type dementia, 1810 mild cognitive impairment, and 788 cognitively normal). Generalized estimating equation models were used to assess APOE epsilon4 prevalence in relation to age, sex, education, and geographical location. RESULTS: The APOE epsilon4 prevalence was 66% in AD-type dementia, 64% in mild cognitive impairment, and 51% in cognitively normal, and it decreased with advancing age in Abeta+ cognitively normal and Abeta+ mild cognitive impairment (P < .05) but not in Abeta+ AD dementia (P = .66). The prevalence was highest in Northern Europe but did not vary by sex or education. DISCUSSION: The APOE epsilon4 prevalence in AD was higher than that in previous studies, which did not require presence of Abeta pathology. Furthermore, our results highlight disease heterogeneity related to age and geographical location. PMID- 29601790 TI - Is Visceral Leishmaniasis the same in HIV-coinfected adults? AB - INTRODUCTION: Visceral Leishmaniasis is the most severe form of disease caused by the Leishmania donovani complex, with significant morbidity and mortality in developing countries. Worse outcomes occur among HIV-positive individuals coinfected with Leishmania. It is unclear, however, if there are significant differences on presentation between Visceral Leishmaniasis patients with or without HIV coinfection. METHODS: We reviewed medical records from adult patients with Visceral Leishmaniasis treated at a reference healthcare center in Fortaleza - Ceara, Brazil, from July 2010 to December 2013. Data from HIV-coinfected patients have been abstracted and compared to non-HIV controls diagnosed with Visceral Leishmaniasis in the same period. RESULTS: Eighty one HIV-infected patients and 365 controls were enrolled. The diagnosis in HIV patients took significantly longer, with higher recurrence and death rates. Kala-azar's classical triad (fever, constitutional symptoms and splenomegaly) was less frequently observed in Visceral Leishmaniasis-HIV patients, as well as jaundice and edema, while diarrhea was more frequent. Laboratory features included lower levels of hemoglobin, lymphocyte counts and liver enzymes, as well as higher counts of blood platelets and eosinophils. HIV-infected patients were diagnosed mainly through amastigote detection on bone marrow aspirates and treated more often with amphotericin B formulations, whereas in controls, rK39 was the main diagnostic tool and pentavalent antimony was primarily used for treatment. CONCLUSIONS: Clinical and laboratory presentation of Visceral Leishmaniasis in HIV-coinfected patients may differ from classic kala-azar, and these differences may be, in part, responsible for the delay in diagnosing and treating leishmaniasis, which might lead to worse outcomes. PMID- 29601792 TI - Effects of iridoid-anthocyanin extract of Cornus mas L. on hematological parameters, population and proliferation of lymphocytes during experimental infection of mice with Trichinella spiralis. AB - The influence of iridoid-anthocyanin aqueous extract of cornelian cherry fruits (CM) on hematological parameters, lymphocyte subsets and proliferation during Trichinella spiralis infection in mice was investigated. CM (100 mg/kg) was administered orally to T. spiralis-infected mice six times within a period encompassing three days prior to the infection and three days after the infection (dai). CM increased the percentage of CD3+, CD4+ cells and CD4+/CD8+ ratio and decreased total count of CD8+ and CD19+ splenocytes (5th dai). An increase in total count of CD4+, CD3+, CD19+ splenocytes was observed (21st dai). CM elevated the percentage of CD4+ cells (7th dai) and CD4+/CD8+ ratio (21st dai) in MLN. CM increased (14th dai) and then reduced (21st dai) the percentage of CD8+ MLN lymphocytes and decreased total count of MLN CD8+ cells (21st dai) and B cells (14th dai). An activation of lymphocyte proliferation in spleen and simultaneous decrease in MLN on 5th dai was observed. An increase in red blood cells parameters (5th dai) and in leukocyte count (7th dai) was found. A rise in platelet count was noticed both on 5th and 7th dai. Moreover, the number of adult T. spiralis on 5th dai in mice receiving CM extract was lower than in the control mice. These results suggested that iridoid-anthocyanin aqueous extract of CM stimulated murine immune response during T. spiralis infection.

AB - INTRODUCTION: Biofilm production is an important mechanism for the survival of Pseudomonas aeruginosa and its relationship with antimicrobial resistance represents a challenge for patient therapeutics. P. aeruginosa is an opportunistic pathogen frequently associated to nosocomial infections, especially in imunocompromised hosts. OBJECTIVES: Analyze the phenotypic biofilm production in P. aeruginosa isolates, describe clonal profiles, and analyze quorum sensing (QS) genes and the occurrence of mutations in the LasR protein of non-biofilm producing isolates. METHODS: Isolates were tested for biofilm production by measuring cells adherence to the microtiter plates. Clonal profile analysis was carried out through ERIC-PCR, QS genes were by specific PCR. RESULTS: The results showed that 77.5% of the isolates were considered biofilm producers. The results of genotyping showed 38 distinct genetic profiles. As for the occurrence of the genes, 100% of the isolates presented the lasR, rhlI and rhlR genes, and 97.5%, presented the lasI gene. In this study nine isolates were not biofilm producers. However, all presented the QS genes. Amplicons related to genes were sequenced in three of the nine non-biofilm-producing isolates (all presenting different genetic similarity profile) and aligned to the sequences of those genes in P. aeruginosa strain PAO1 (standard biofilm-producing strain). Alignment analysis showed an insertion of three nucleotides (T, C and G) causing the addition of an amino acid valine in the sequence of the LasR protein, in position 53. CONCLUSION: The modeling of the resulting LasR protein showed a conformational change in its structure, suggesting that this might be the reason why these isolates are unable to produce biofilm. PMID- 29601793 TI - Novel univariate and multivariate regression methods for the simultaneous analysis of ternary mixture of 1, 4-benzodiazepines in dosage forms and human urine. AB - In this paper, novel univariate and multivariate regression model updating methods were developed and validated for the simultaneous determination of ternary mixture of bromazepam, diazepam and clonazepam. The univariate methods used are the mean centering of ratio spectrophotometric method and iso-absorptive point coupled with ratio-subtraction and ratio difference spectrophotometric method. Linearity, ranges, precision and accuracy of these methods were determined. The multivariate methods adopted are the principal component regression and partial least-squares. These models were estimated using nineteen mixtures as calibration set and six mixtures as validation set. The minimum root square error of predication were 0.1215 and 0.0568 for BMZ, 0.0598 and 0.0712 for DIZ and 0.0867 and 0.0753 for CNP by PLS and PCR respectively. PCR and PLS methods were successfully applied for the analysis of BMZ, DIZ and CNP in their dosage forms. Content uniformity testing of the studied pharmaceutical tablets by PLS and PCR was also determined. MCR, IPRSRD and PLS model updating enabled the determination of BMZ, DIZ and CNP in spiked human urine. Moreover, PLS model updating was applied to drug-dissolution rate testing of BMZ and DIZ in their commercial tablets. The obtained results were statistically compared with those obtained by reported methods giving a conclusion that there is no significant difference regarding accuracy and precision.

PMID- 29601799 TI - The three branches of the unfolded protein response exhibit differential significance in breast cancer growth and stemness. AB - The unfolded protein response (UPR) is widely activated in cancers. The mammalian UPR encompasses three signaling branches, namely inositol-requiring enzyme-1alpha (IRE1alpha), protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) and activating transcription factor 6alpha (ATF6alpha). The functional significance of each branch in tumorigenesis is incompletely understood, especially in cancer stem cells (CSCs). Here, we report that inhibition and silencing of the three UPR sensors has differential effects on breast cancer growth and the CSC population. The levels of PERK and ATF6alpha strongly correlate with the expression of sex determining region Y (SRY)-box 2 (SOX2), a pluripotency regulator, in human breast cancer tissues. UPR activation is also elevated in the CSC-enriched mammospheres. Inhibition of the UPR sensors or excess ER stress markedly reduces the formation and maintenance of mammospheres, suggesting that an appropriate level of UPR activation is critical for the CSC survival. Mechanistically, transcription factors from UPR and pluripotency pathways interact and reciprocally influence each other. A transcription modulator, CCAAT-enhancer binding protein delta (C/EBPdelta), interacts with pluripotency regulator, SOX2, and UPR transcription factors, thus likely serving as a link to coordinate UPR and pluripotency maintenance in CSCs. Our findings demonstrate that UPR is critical for both cancer growth and pluripotency, and highlight the differential role and complexity of the three UPR branches in tumorigenesis.

AB - Ossification of the ligamentum flavum (OLF) is a debilitating disease resulting from the development of ectopic bone formation, which leads to the compression of the spinal cord. Nicotinamide phosphoribosyltransferase (NAMPT) was found to be upregulated and microRNA-182 (miR-182) was downregulated in OLF tissue. We investigated the effects of NAMPT and miR-182 expression in OLF cells and the influence on proteins associated with osteogenic differentiation. MiR-182 overexpression inhibited NAMPT, RUNX2, OCN and OPN mRNA and protein expression in OLF cells. Alkaline phosphatase (ALP) assay and Alizarin red staining confirmed reduced levels of osteogenic differentiation and mineralized nodule formation. Knockdown of NAMPT and the NAMPT inhibitor FK866 also inhibits RUNX2, OCN and OPN mRNA expression and protein levels, whereas overexpression of NAMPT promotes the expression of RUNX2, OCN and OPN and the generation of bone nodules. Dual luciferase reporter assays revealed that miR-182 directly targets NAMPT and downregulates its expression. Transfection of OLF cells with miR-182 downregulated NAMPT and suppressed the regulation of RUNX2, OCN, and OPN by NAMPT overexpression. Overall, these data demonstrate that miR-182 suppresses OLF by downregulating NAMPT. PMID- 29601801 TI - The accuracy of transcutaneous bilirubinometer measurements to identify the hyperbilirubinemia in outpatient newborn population. AB - OBJECTIVES: To assess the ability of transcutaneous bilirubinometer for prediction total serum bilirubin levels in newborn infants after hospital discharge. METHODS: Newborn infants requiring total serum bilirubin (TSB) level measurement during an outpatient follow-up visit were included into the study. Transcutaneous bilirubin (TcB) measurement was carried out using JH20-1C (Ningbo David, China) transcutaneous jaundice detector and total serum bilirubin was simultaneously determined by direct spectrophotometry. The agreement between paired TSB and TcB measurements were assessed by Bland-Altman plot and Deming regression analysis. Predictive indices were also identified in different TcB cut off values for TSB levels of 222, 256 and 291 MUmol/L. RESULTS: A total of 271 paired TcB and TSB measurements were obtained from 218 newborn infants. 40.2% had an age of above 7 days at measurement time. The mean difference (95% CI) between TcB and TSB values was -1.7 (-5.4 to 2.1) MUmol/L. For TSB levels of at least 256 and 291 MUmol/L, a TcB cut-off of 222 MUmol/L shows sensitivity of 90.6% and 100%, respectively. It was also determined that 39.4% of TSB measurements could be avoided when using TcB cut-off value of 222 MUmol/L. CONCLUSION: The measurement of TcB with JH20-1C seems to be a reliable screening method for hyperbilirubinemia in the outpatient population when used a TcB cut-off of 222 MUmol/L. The use of transcutaneous bilirubinometer could reduce the number of invasive blood sampling for the determination serum bilirubin.

AB - With the potential uses of carbon nanotubes (CNTs) in biomedical and biotechnological applications, and the growing concerns about nanotoxicity of these engineered nanoparticles, the importance of protein-nanoparticle interaction has not been well stressed. In this study, we used both experimental and theoretical approaches to investigate the interactions of different functionalized single-walled CNTs (SWCNTs) with human serum albumin (HSA). It was found that the HSA adsorption capacities of CNTs followed the order carboxylated SWCNTs > hydroxylated SWCNTs > amined SWCNTs. The fluorescence intensity of HSA was quenched by all of the three SWCNTs in static mode, which was authenticated by Stern-Volmer calculations. Our molecular dynamics simulations revealed that both atom-atom contact numbers and binding energies between functionalized SWCNTs and HSA played critical roles in determining their adsorption capacity, in agreement with the experimental findings. Additional cytotoxicity assays revealed that coating of carboxylated CNTs with HSA more significantly reduced their cytotoxicity than the other two CNTs, in agreement with their protein adsorption capacities in vitro. These findings will be helpful to clarify the mechanism of interactions of functionalized SWCNTs with human serum proteins, and provide more insight into the understanding of how to design the safe nanoparticles by preconsideration of their interactions with proteins. PMID- 29601806 TI - Remote Ischemic Preconditioning Does Not Prevent White Matter Injury in Neonates. AB - BACKGROUND: Remote ischemic preconditioning (RIPC) is a mechanism to protect tissues from injury during ischemia and reperfusion. We investigated the neuroprotective effects of RIPC in neonates undergoing cardiac surgery. METHODS: The outcome was white matter injury (WMI), assessed by the change in volume of WMI from preoperative to postoperative brain magnetic resonance imaging (MRI). Patients were randomized to RIPC or SHAM. RIPC was induced prior to cardiopulmonary bypass by four 5-minute cycles of blood pressure cuff inflation to produce ischemia of the lower extremity. For patients randomized to SHAM, the cuff was positioned, but not inflated. RESULTS: The study included 67 patients, with 33 randomized to RIPC and 34 randomized to SHAM. Preoperative and postoperative MRIs were available in 50 patients, including 26 of the 33 RIPC patients and 24 of the 34 SHAM patients. There were no differences in baseline and operative characteristics for either the overall study group or the group with evaluable MRIs. WMI was identified in 28% of the patients preoperatively and in 62% postoperatively. There was no difference in the prevalence of WMI by treatment group (p > 0.5). RIPC patients had an average change in WMI of 600 mL3, and SHAM subjects had an average WMI change of 107 mL3. There was no significant difference in the mean value of WMI change between patients who received RIPC and those who received SHAM treatments (p = 0.178). CONCLUSIONS: In this randomized, blinded clinical trial, there was no evidence that use of RIPC provides neuroprotection in neonates undergoing repair of congenital heart defects with cardiopulmonary bypass. PMID- 29601807 TI - Utility of Site-Specific Biopsy for Diagnosis of Desmoplastic Malignant Mesothelioma. AB - Desmoplastic malignant mesothelioma (DMM) is a relatively rare histologic subtype of malignant pleural mesothelioma (MPM). Among MPMs, the diagnosis of DMM is particularly difficult because the tumor is largely composed of dense hyalinized fibrous stroma and few malignant cells. We present two cases of DMM, one in a 47 year-old man and the other in a 64-year-old man. From detailed pathologic findings in these two cases, we conclude that cases of DMM that cannot otherwise be diagnosed with the use of conventional pleural biopsy, may be diagnosed successfully with the use of wedge lung resection.

PMID- 29601809 TI - Hatching synchrony is controlled by a two-step mechanism in the migratory locust Locusta migratoria (Acrididae: Orthoptera): Roles of vibrational stimuli. AB - The eggs of the migratory locust, Locust migratoria, hatch in synchrony from their pod. In this study, we examined the mechanism controlling hatching synchrony. Two eggs obtained from the same pod hatched in synchrony when kept in contact with one another, whereas those separated by a few millimeters hatched less synchronously. When a screen separated the eggs, the hatching was even more sporadic, indicating that hatching synchrony might be controlled by a two-step mechanism. We hypothesize that in the first step the embryos shortly before hatching control the time to enter a standby stage using some signal from neighboring eggs. The eggs in the standby stage hatch promptly when an additional stimulus is received from neighboring eggs. Before this stage, eggs cannot respond to that stimulus by hatching but may spontaneously hatch later. Introduction of a newly hatched nymph to single eggs 1 or 2 days before hatching advanced hatching of these eggs, but hatching occurred only sporadically. Eggs kept in contact with other eggs that had been killed by freezing shortly before hatching hatched as if they had been kept singly in separate containers, providing no evidence for involvement of chemical stimuli in controlling hatching synchrony. By contrast, eggs separated by several millimeters hatched as synchronously as those kept in contact with one another when they were connected by a piece of wire. Furthermore, vibrational stimulation derived from music greatly advanced hatching of separately kept eggs; however, hatching synchrony was not achieved unless the music started shortly before hatching. These results are consistent with the two-step hypothesis and indicated that locust embryos used vibrational stimuli from neighboring eggs for synchronous hatching.

AB - This study investigates the effect and the underlying mechanism of 2',3-dihydroxy 5-methoxybiphenyl (RIR-2), a lignan extracted from the roots of Rhaphiolepis indica (L.) Lindl. ex Ker var. tashiroi Hayata ex Matsum. & Hayata (Rosaceae), on N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP)-induced respiratory burst and cathepsin G in human neutrophils. Signaling pathways regulated by RIR-2 which modulated fMLP-induced respiratory burst were evaluated by an interaction between beta subunit of G-protein (Gbeta) with downstream signaling induced by fMLP and by immunoblotting analysis of the downstream targets of Gbeta-protein. RIR-2 inhibited fMLP-induced superoxide anion production (IC50:2.57 +/- 0.22 MUM), cathepsin G release (IC50:18.72 +/- 3.76 MUM) and migration in a concentration dependent manner. RIR-2 specifically suppresses fMLP-induced Src family kinases phosphorylation by inhibiting the interaction between Gbeta-protein with Src kinases without inhibiting Src kinases activities, therefore, RIR-2 attenuated the downstream targets of Src kinase, such as phosphorylation of Raf/ERK, AKT, P38, PLCgamma2, PKC and translocation Tec, p47ph degrees x and P40ph degrees x from the cytosol to the inner leaflet of the plasma membrane. Furthermore, RIR-2 attenuated fMLP-induced intracellular calcium mobilization by inhibiting the interaction between Gbeta-protein with PLCbeta2. RIR-2 was not a competitive or allosteric antagonist of fMLP. On the contrary, phorbol 12-myristate 13-acetate (PMA)-induced phosphorylation of Src, AKT, P38, PKC and membrane localization of p47ph degrees x and P40ph degrees x remained unaffected. RIR-2 specifically modulates fMLP-mediated neutrophil superoxide anion production and cathepsin G release by inhibiting the interaction between Gbeta-protein with downstream signaling which subsequently interferes with the activation of intracellular calcium, PLCgamma2, AKT, p38, PKC, ERK, p47ph degrees x and p40phox.

AB - Bacterial Na+-transporting rhodopsins convert solar energy into transmembrane ion potential difference. Typically, they are strictly specific for Na+, but some can additionally transport H+. To determine the structural basis of cation promiscuity in Na+-rhodopsins, we compared their primary structures and found a single position that harbors a cysteine in strictly specific Na+-rhodopsins and a serine in the promiscuous Krokinobacter eikastus Na+-rhodopsin (Kr2). A Cys253Ser variant of the strictly specific Dokdonia sp. PRO95 Na+-rhodopsin (NaR) was indeed found to transport both Na+ and H+ in a light-dependent manner when expressed in retinal-producing Escherichia coli cells. The dual specificity of the NaR variant was confirmed by analysis of its photocycle, which revealed an acceleration of the cation-capture step by comparison with the wild-type NaR in a Na+-deficient medium. The structural basis for the dependence of the Na+/H+ specificity in Na+-rhodopsin on residue 253 remains to be determined. PMID- 29601813 TI - Effects of cell adhesion motif, fiber stiffness, and cyclic strain on tenocyte gene expression in a tendon mimetic fiber composite hydrogel. AB - We recently developed a fiber composite consisting of tenocytes seeded onto discontinuous fibers embedded within a hydrogel, designed to mimic physiological tendon micromechanics of tension and shear. This study examined if cell adhesion peptide (DGEA or YRGDS), fiber modulus (50 or 1300 kPa) and/or cyclic strain (5% strain, 1 Hz) influenced bovine tenocyte gene expression. Ten genes were analyzed and none were sensitive to peptide or fiber modulus in the absence of cyclic tensile strain. Genes associated with tendon (SCX and TNMD), collagens (COL1A1, COL3A1, COL11A1), and matrix remodelling (MMP1, MMP2, and TIMP3) were insensitive to cyclic strain. Contrarily, cyclic strain up-regulated IL6 by 30-fold and MMP3 by 10-fold in soft YRGDS fibers. IL6 expression in soft YRGDS fibers was 5.7 and 3.3-fold greater than in soft DGEA fibers and stiff RGD fibers, respectively, under cyclic strain. Our findings suggest that changes in the surrounding matrix can influence catabolic genes in tenocytes when cultured in a complex strain environment mimicking that of tendon, while having minimal effects on tendon and homeostatic genes. PMID- 29601814 TI - Isolation and identification of two new alleles of STICHEL in Arabidopsis. AB - Plant trichome has long been selected as a model system to study the regulatory mechanism during cell development due to its unique growth characteristics. In an effort to explore new components that contribute to trichome development, we performed large-scale forward genetic screening in Arabidopsis, and found two recessive mutants with significant trichome branching defects, both of which display one branched trichomes. After map-based cloning, genetic complementation experiments, we confirmed that they are new alleles of STICHEL (STI) that has been reported to act as a key regulator of trichome branching. The predicted product of STI gene is comprised by three functional domains including a large domain with sequence similarity to eubacterial DNA polymerase III gamma-subunit in the middle, two PEST domains in the N terminal, and two nuclear localization signals (NLS) at the very N terminal and C terminal, respectively. Our biochemistry and molecular analysis indicated that a PEST domain in the N terminal could be important for STI functioning in regulating trichome branching. It can directly interact with BRACHLESS TRICHOME (BLT), an important linker of cell shape and endoreplication. Because the previously data showed that the function of STI in regulating trichome branching was not linked to DNA replication and actin or microtubule cytoskeleton configuration, our findings of the direct interaction domains between STI and BLT veiled the probable roles of STI in cell morphogenesis. PMID- 29601815 TI - Discovery and characterization of selective small molecule inhibitors of the mammalian mitochondrial division dynamin, DRP1. AB - Balanced rates of mitochondrial division and fusion are required to maintain mitochondrial function, as well as cellular and organismal homeostasis. In mammals, the cellular machines that mediate these processes are dynamin-related GTPases; the cytosolic DRP1 mediates division, while the outer membrane MFN1/2 and inner membrane OPA1 mediate fusion. Unbalanced mitochondrial dynamics are linked to varied pathologies, including cell death and neurodegeneration, raising the possibility that small molecules that target the division and fusion machines to restore balance may have therapeutic potential. Here we describe the discovery of novel small molecules that directly and selectively inhibit assembly stimulated GTPase activity of the division dynamin, DRP1. In addition, these small molecules restore wild type mtDNA copy number in MFN1 knockout mouse embryonic fibroblast cells, a phenotype linked to deficient mitochondrial fusion activity. Thus, these compounds are unique tools to explore the roles of mitochondrial division in cells, and to assess the potential therapeutic efficacy of rebalancing mitochondrial dynamics in pathologies associated with excessive mitochondrial division. PMID- 29601816 TI - Biophysical study of human induced Pluripotent Stem Cell-Derived cardiomyocyte structural maturation during long-term culture. AB - Human induced Pluripotent Stem Cell-derived cardiomyocytes (hiPSC-CMs) have an enormous potential for the development of drug screening and modeling cardiac disease platforms. However, early hiPSC-CMs usually exhibit low structural development, precluding the applicability of these cells. Here, we follow during 120 days the progressive structural maturation of hiPSC-CM microtissues obtained using the Wnt signaling modulation protocol. For this purpose, we designed a user friendly custom-written program to quantify cardiac fiber alignment and sarcomere length. Cardiomyocyte shape, cardiac fiber density and multinucleation were also analyzed. Derived cardiomyocytes showed significant progression in cardiomyocyte fiber density and sarcomere length during the long-term culture, with a peak at day 90 of 40% multinucleated cells. In addition, cardiomyocyte microtissues remained functional with progressive maturation leading to a decrease in the percentage of cTnT positive cells from 59% to 22% at day 120, a value similar to the content present in tissues of the adult left ventricle. These data and the framework that we provide to quantify cardiomyocyte structural features can be important to set new metrics to develop applications for drug screening and disease modeling. PMID- 29601818 TI - Hepatic NPC1L1 promotes hyperlipidemia in LDL receptor deficient mice. AB - BACKGROUND AND AIMS: Niemann-Pick C1-like1 (NPC1L1), a crucial cholesterol absorption receptor expressed in human intestine and liver. But in mouse it is only expressed in intestine. Previous studies elucidated that expression of human NPC1L1 in mouse liver led to increase of plasma cholesterol due to activation of absorption from bile. However, hepatic NPC1L1 function was not elucidated in LDL receptor deficient mouse (LDLR-/-) in which LDL was a main lipoprotein as in human. METHODS AND RESULTS: L1-Tg/LDLR-/- mouse was created by crossing liver specific NPC1L1 transgenic mouse (L1-Tg) with LDLR-/-. L1-Tg/LDLR-/- mice developed hyperlipidemia when fed with atherogenic diet (AD) containing 0.2% cholesterol for 21days. Compared with control mice, biliary cholesterol level in L1-Tg/LDLR-/- mice was significantly lower, plasma cholesterol level was significantly higher in L1-Tg/LDLR-/- mice under both chow diet and AD feeding. New finding in this study is augmentations of plasma TAG L1-Tg/LDLR-/- mice fed with AD. Results were shown that very low density lipoprotein (VLDL) secretion was elevated in L1-Tg/LDLR-/- mice after AD fed. The increase of VLDL secretion was further confirmed by higher expression of hepatic triacylglycerol hydrolase (TGH) and microsomal triglyceride transfer protein (MTP). CONCLUSION: L1-Tg/LDLR /- mouse is a humanized model to study cholesterol absorption and transportation. The results obtained from L1-Tg/LDLR-/- mouse indicated no feedback mechanism to inhibit NPC1L1 function in liver and hepatic expression of NPC1L1 correlated with VLDL secretion in hypercholesterolemia state. PMID- 29601817 TI - GLP-1 receptor agonist liraglutide exerts central action to induce beta-cell proliferation through medulla to vagal pathway in mice. AB - Endogenous GLP-1 and GLP-1 receptor agonists (GLP-1RAs) regulate glucose metabolism via common and distinct mechanisms. Postprandial release of GLP-1 is modest and it is degraded by DPP-4 within 2 min, and hence it cannot enter the brain in substantial amount. In contrast, DPP-4-resistant GLP-1RAs are administered at 10 times higher concentration than endogenous GLP-1 level, which enables them to reach several brain regions including ARC and AP, the areas implicated in glucose metabolism. Hence, some of the effects of GLP-1RAs observed clinically and experimentally, including pancreatic beta-cell proliferation, are thought to involve the brain. However, the effects of centrally acting GLP-1/GLP 1RAs on glucose metabolism and underlying neural mechanism are unclear. This study aimed to establish the link of central GLP-1/GLP-1RA action to pancreatic beta-cell proliferation. Both subcutaneous (SC) and intracerebroventricular (ICV) injections of liraglutide increased the number of pancreatic beta-cells expressing Ki67 and PCNA, proliferation markers, in C57BL/6J mice. This effect was induced by single ICV administration of liraglutide at relatively low dose that was incapable of suppressing food intake. These SC and ICV liraglutide induced effects were inhibited by 50% and 70%, respectively, by pretreatment with atropine, a muscarinic receptor blocker. ICV liraglutide induced c-Fos expression in the area postrema (AP), nucleus tractus solitaries (NTS), and dorsal motor nucleus of the vagus (DMX) of the brain stem. These results demonstrate that central action of liraglutide induces pancreatic beta-cell proliferation via the pathway involving the brain stem AP/NTS/DMX area and vagus nerve. This route is highly sensitive to GLP-1/GLP-1RA. Hence, this brain-pancreatic beta-cell pathway may operate in type 2 diabetic patients treated with GLP-RAs and serve to counteract the reduction of beta-cell mass. PMID- 29601819 TI - The crystal structure and oligomeric form of Escherichia colil,d-carboxypeptidase A. AB - Bacterial peptidoglycan is constructed by cross-linking sugar chains carrying pentapeptide building blocks with two d-alanine residues at the C-terminus. Incorporation into the polymer and subsequent breakdown of peptidoglycan releases a tetrapeptide with a single d-alanine residue. Removal of this residue is necessary for the tripeptide to receive a new D-Ala-D-Ala dipeptide in the synthetic pathway, but proteases are generally unable to work with substrates having residues of unusual chirality close to the scissile bond. Processing of the tetrapeptide is carried out by a dedicated ld-carboxypeptidase, which is of interest as a novel drug target. We describe the high resolution crystal structure of the enzyme from E. coli, and demonstrate the dimeric structure is highly conserved. PMID- 29601820 TI - Dense B-Scan Optical Coherence Tomography Angiography. AB - PURPOSE: To describe a novel imaging technique, which we call "dense B-scan optical coherence tomography angiography" (DB OCTA), in which thin dense raster scans are used to produce highly resolved structural B-scans with superimposed flow signal that provide precise correlation between retinal microstructure and blood flow. DESIGN: Observational case series. METHODS: Normal eyes and eyes with macular findings of interest were imaged with DB OCTA in which 150-400 OCT B scans were acquired within a narrow area (from a single line to 1 degree) with a width of 10-30 degrees. B-scans containing 5-7 consecutive frames were processed for OCTA signal and then combined and visualized post-acquisition by application of a Gaussian filter across neighboring scans. The result was a single, smoothed, high-resolution image that contained both structural and flow information. Tracked follow-up DB OCTA was used to detect subtle changes in pathology over time. RESULTS: Two hundred and thirty-seven eyes from 205 subjects aged 18-100 years (mean 72.88 +/- 14.74 years) with a diverse range of macular findings were imaged with DB OCTA. Highly resolved scans showing precise localization of flow signal were readily obtained, even in patients with poor visual acuity and/or poor fixation. We present clinical examples that demonstrate the utility of DB OCTA for visualizing the associations between retinal microstructure and blood flow. CONCLUSIONS: DB OCTA enables precise correlation between retinal microstructure and blood flow. The ability to obtain accurately aligned follow-up DB OCTA studies has the potential to refine the understanding and clinical management of a wide range of macular diseases. PMID- 29601821 TI - Chronic Anterior Uveitis in Children: Psychosocial Challenges for Patients and Their Families. AB - PURPOSE: To describe issues of concern to children with chronic anterior uveitis; to consider the psychological impact of chronic anterior uveitis on children's lives; and to understand the effect of a child's chronic illness on other family members. DESIGN: Expert commentary. METHODS: Author experiences were supplemented by a review of pertinent medical literature and by consideration of content from semi-structured, separate patient and parent interviews. RESULTS: Vision loss and the fear of blindness are not the only stressors for children with chronic anterior uveitis and their families; of additional concern are the burdens of examinations and treatment regimens, as well as drug toxicities. Children with chronic anterior uveitis experience medical, academic, interpersonal, psychological, and developmental challenges. The impact of disease extends to other members of a patient's family as well; parents experience challenges in similar domains. Problems with adherence to medical regimens are common. Both the disease and its treatment affect quality of life, and can interfere with successful management of disease and transition to autonomy in adulthood, as reported for other chronic conditions. Coping processes vary greatly between different families. CONCLUSIONS: Eye examinations and the rigors of long-term treatment often influence the psychosocial health of patients and families; physicians who are aware of these issues can help patients and families cope with chronic illness and may improve outcomes. Further psychosocial research to understand the experiences of children dealing with chronic anterior uveitis is warranted; this commentary can serve as a foundation for development of age- and disease-specific research questions. PMID- 29601822 TI - Pars Plana Vitrectomy for the Treatment of Uveitis. AB - PURPOSE: To review and summarize evidence in the medical literature regarding the use of pars plana vitrectomy in the management of uveitis. DESIGN: Systematic literature review. METHODS: A systematic literature search was conducted for relevant articles on pars plana vitrectomy for the management of uveitis. Results from the studies were compiled and analyzed. RESULTS: Thirty-four articles, published from 2005 through 2014, were included in the final data analysis. Thirty-two manuscripts were from retrospective case series and 2 manuscripts were from randomized pilot studies. The median Scottish Intercollegiate Guidelines Network level of evidence grade was 3 and the median Oxford Center for Evidence based Medicine level of evidence grade was 4. Fewer than 50% of the articles in the current study applied Standardization of Uveitis Nomenclature (SUN) criteria in regard to reporting the anatomic location of uveitis, fewer than 25% of studies applied SUN criteria in regard to the reporting of anterior chamber cells before and after PPV, fewer than 10% of studies applied SUN criteria to the grading of anterior chamber flare before and after PPV, and fewer than 10% of studies applied standardized criteria to the grading of vitreous haze after PPV. Overall, 627 patients and 708 total eyes undergoing PPV for uveitis were included. The average reported age of all patients was 43.4 years. The median duration of uveitis prior to PPV reported in the studies was 36.1 months (range 4 198 months). The median follow-up after PPV reported in the studies was 18.9 months (range 2-114 months). Vision was reported for 519 eyes and was improved in 356 eyes (69%), unchanged in 95 eyes (18%), and worse in 68 eyes (13%) following PPV. Preoperatively, 157 of 300 (52%) eyes in these studies had documented cystoid macular edema compared to 112 of 300 (37%) postoperatively. Median use of oral corticosteroids improved from 48% preoperatively to 12% postoperatively among the reporting studies. Median use of other immunosuppressive medications decreased from 56% preoperatively to 36% postoperatively among the reporting studies. CONCLUSIONS: Although nearly all studies continue to report favorable outcomes of PPV in the management of uveitis, the quality of data remains limited by a lack of application of standardized reporting outcomes, limitations in study design, and a paucity of prospective data. PMID- 29601823 TI - Cholesterol modulates the binding properties of human relaxin family peptide receptor 3 with its ligands. AB - Relaxin family peptide receptor 3 (RXFP3) is implicated in the regulation of food intake and stress response upon activation by its cognate agonist relaxin-3. As an A-class G protein-coupled receptor, RXFP3 is an integral plasma membrane protein with seven transmembrane domains, yet influence of the membrane lipids on its function remains unknown. In the present study, we disclosed that cholesterol, an essential membrane lipid for mammalian cells, modulated the binding properties of human RXFP3 with its ligands. We first demonstrated that depletion of cholesterol from host human embryonic kidney (HEK) 293T cells by methyl-beta-cyclodextrin altered ligand-binding properties of the overexpressed human RXFP3, such as increasing its binding potency with some antagonists and decreasing its binding affinity with a NanoLuc-conjugated R3/I5 tracer. Thereafter, we demonstrated that two B-chain residues, B5Tyr and B12Arg, were primarily responsible for the increased binding potency of these antagonists with human RXFP3 under the cholesterol depletion condition. Our results suggest that cell membrane cholesterol interacts with human RXFP3 and modulates its ligand binding properties, providing new insights into the influence of membrane lipids on RXFP3 function. PMID- 29601824 TI - Optical assessment of skin carotenoid status as a biomarker of vegetable and fruit intake. AB - Resonance Raman spectroscopy (RRS) and reflection spectroscopy (RS) are optical methods applicable to the non-invasive detection of carotenoids in human skin. RRS is the older, more thoroughly validated method, whereas RS is newer and has several advantages. Since collective skin carotenoid levels serve as a biomarker for vegetable and fruit intake, both methods hold promise as convenient screening tools for assessment of dietary interventions and correlations between skin carotenoids and health and disease outcomes. In this manuscript, we describe the most recent optimized device configurations and compare their use in various clinical and field settings. Both RRS and RS devices yield a wide range of skin carotenoid levels between subjects, which is a critical feature for a biomarker. Repeatability of the methods is 3-15% depending on the subject's skin carotenoid level and the uniformity of its local distribution. For 54 subjects recruited from an ophthalmology clinic, we first checked the validity of the relatively novel RS methodology via biochemical serum carotenoid measurements, the latter carried out with high performance liquid chromatography (HPLC). A high correlation between RS skin and serum HPLC carotenoid levels was established (R = 0.81; p < 0.001). Also, a high correlation was found between RS and RRS skin levels (R = 0.94 p < 0.001). Subsequent comparisons of skin carotenoid measurements in diverse age groups and ethnicities included 569 Japanese adults, 947 children with ages 2-5 screened in 24 day care centers in San Francisco, and 49 predominantly Hispanic adults screened at an outdoor health fair event. Depending on the particular subject group, correlation coefficients between the RRS and RS methods ranged between R ~0.80 and R ~0.96. Analysis of the Japanese screening showed that, on average, skin carotenoid levels are higher in women compared to men, skin levels do not depend on age, and tobacco smokers have reduced levels versus non-smokers. For the two most ethnically diverse groups with widely varying melanin levels, we investigated the effect of dermal melanin on RS and RRS skin carotenoid levels. The analysis revealed that large variations in skin carotenoid levels remain detectable independent of the particular melanin index. This behavior is consistent with the absence of melanin effects on the skin carotenoid levels generated with the instrument configurations. The RS method has an advantage over RRS in its relative simplicity. Due to its detection of skin reflection over a wide spectral range from the near UV to the near IR, it has the unique ability to quantify each of the major tissue chromophores and take them into account in the derivation of skin carotenoid levels.

PMID- 29601825 TI - Identification of Endpoints for Development of Antifibrosis Drugs for Treatment of Crohn's Disease. AB - BACKGROUND & AIMS: Intestinal fibrosis is a challenge to management of patients with Crohn's disease (CD); there is an urgent need to expedite development of antifibrosis drugs for this disease. The International Organization for the Study of Inflammatory Bowel Disease (IOIBD) aimed to identify a set of endpoints that can be used to determine efficacy of antifibrosis agents tested in clinical trials of patients with CD. METHODS: We conducted a systematic review to identify clinical, radiologic, biochemical, endoscopic, and composite endpoints used in assessing activity of fibrostenosing CD and response to treatment, and determined their operational properties. A panel of IOIBD experts performed a consensus process to identify the best endpoints for inclusion in clinical trials, through a 2-round, Delphi-style online survey. RESULTS: A total of 36 potentially relevant endpoints for intestinal fibrosis were selected and assessed. Forty eight physicians with expertise in inflammatory bowel disease, from 5 regions (North America, Europe, Middle East, Asia/Pacific, and Latin America), participated in the Delphi consensus process. A core set of 13 endpoints (complete clinical response, long-term efficacy, sustained clinical benefit, treatment failure, radiological remission, normal quality of life, clinical remission without steroids, therapeutic failure, deep remission, complete absence of occlusive symptoms, symptom-free survival, bowel damage progression, and no disability) were rated as critical. Agreement was high among the experts. CONCLUSIONS: Members of the IOIBD reached expert consensus on a set of endpoints that can be used to assess antifibrosis agents in trials of patients with CD. Studies are needed to clarify methods for measuring these outcomes and validate measurement instruments.

PMID- 29601828 TI - Identification of Variants in RET and IHH Pathway Members in a Large Family With History of Hirschsprung Disease. AB - BACKGROUND & AIMS: Hirschsprung disease (HSCR) is an inherited congenital disorder characterized by absence of enteric ganglia in the distal part of the gut. Variants in ret proto-oncogene (RET) have been associated with up to 50% of familial and 35% of sporadic cases. We searched for variants that affect disease risk in a large, multigenerational family with history of HSCR in a linkage region previously associated with the disease (4q31.3-q32.3) and exome wide. METHODS: We performed exome sequencing analyses of a family in the Netherlands with 5 members diagnosed with HSCR and 2 members diagnosed with functional constipation. We initially focused on variants in genes located in 4q31.3-q32.3; however, we also performed an exome-wide analysis in which known HSCR or HSCR associated gene variants predicted to be deleterious were prioritized for further analysis. Candidate genes were expressed in HEK293, COS-7, and Neuro-2a cells and analyzed by luciferase and immunoblot assays. Morpholinos were designed to target exons of candidate genes and injected into 1-cell stage zebrafish embryos. Embryos were allowed to develop and stained for enteric neurons. RESULTS: Within the linkage region, we identified 1 putative splice variant in the lipopolysaccharide responsive beige-like anchor protein gene (LRBA). Functional assays could not confirm its predicted effect on messenger RNA splicing or on expression of the mab-21 like 2 gene (MAB21L2), which is embedded in LRBA. Zebrafish that developed following injection of the lrba morpholino had a shortened body axis and subtle gut morphological defects, but no significant reduction in number of enteric neurons compared with controls. Outside the linkage region, members of 1 branch of the family carried a previously unidentified RET variant or an in-frame deletion in the glial cell line derived neurotrophic factor gene (GDNF), which encodes a ligand of RET. This deletion was located 6 base pairs before the last codon. We also found variants in the Indian hedgehog gene (IHH) and its mediator, the transcription factor GLI family zinc finger 3 (GLI3). When expressed in cells, the RET-P399L variant disrupted protein glycosylation and had altered phosphorylation following activation by GDNF. The deletion in GDNF prevented secretion of its gene product, reducing RET activation, and the IHH-Q51K variant reduced expression of the transcription factor GLI1. Injection of morpholinos that target ihh reduced the number of enteric neurons to 13% +/- 1.4% of control zebrafish. CONCLUSIONS: In a study of a large family with history of HSCR, we identified variants in LRBA, RET, the gene encoding the RET ligand (GDNF), IHH, and a gene encoding a mediator of IHH signaling (GLI3). These variants altered functions of the gene products when expressed in cells and knockout of ihh reduced the number of enteric neurons in the zebrafish gut.

PMID- 29601829 TI - Thirty-Day Readmission Among Patients With Non-Variceal Upper Gastrointestinal Hemorrhage and Effects on Outcomes. AB - BACKGROUND & AIMS: We aimed to determine the rate of hospital readmission within 30 days of non-variceal upper gastrointestinal hemorrhage and its impact on mortality, morbidity, and health care use in the United States. METHODS: We performed a retrospective study using the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmission Database for the year 2014 (data on 14.9 million hospital stays at 2048 hospitals in 22 states). We collected data on hospital readmissions of 203,220 adults who were hospitalized for urgent non-variceal upper gastrointestinal hemorrhage and discharged. The primary outcome was rate of all-cause readmission within 30 days of discharge. Secondary outcomes were reasons for readmission, readmission mortality rate, morbidity (shock and prolonged mechanical ventilation) and resource use (length of stay and total hospitalization costs and charges). Independent risk factors for readmission were identified using Cox regression analysis. RESULTS: The 30-day rate of readmission was 13%. Only 18% of readmissions were due to recurrent non-variceal upper gastrointestinal bleeding. The rate of death among patients readmitted to the hospital (4.7%) was higher than that for index admissions (1.9%) (P < .01). A higher proportion of readmitted patients had morbidities requiring prolonged mechanical ventilation (1.5%) compared with index admissions (0.8%) (P < .01). A total of 133,368 hospital days was associated with readmission, and the total health care in hospital economic burden was $30.3 million (in costs) and $108 million (in charges). Independent predictors of readmission were Medicaid insurance, higher Charlson comorbidity score, lower income, residence in a metropolitan area, hemorrhagic shock, and longer stays in the hospital. Older age, private or no insurance, upper endoscopy, and prolonged mechanical ventilation were associated with lower odds for readmission. CONCLUSIONS: In a retrospective study of patients hospitalized for non-variceal upper gastrointestinal hemorrhage, 13% are readmitted to the hospital within 30 days of discharge. Readmission is associated with higher mortality, morbidity, and resource use. Most readmissions are not for recurrent gastrointestinal bleeding. PMID- 29601831 TI - Enhanced amphetamine-induced motor impulsivity and mild attentional impairment in the leptin-deficient rat model of obesity. AB - Evidence suggests that impulse control deficits contribute to excessive food intake in some individuals with obesity. In addition to its known role in regulating appetite and glucose metabolism, the hormone leptin also directly modulates the activity of central dopamine systems. Although dopamine is involved in regulating impulsivity, the influence of leptin per se on this cognitive domain remains unclear. This study explored the performance of male leptin knockout (KO) and wild type (WT) rats in the 5-Choice Serial Reaction Time task (5CSRTT) of motor impulsivity and visuospatial attention. Behavioural performance was assessed under baseline conditions, following 4 weeks high-fat diet (HFD; 60 kcal%) consumption, and after acute pharmacological challenge with the indirect dopamine agonist, amphetamine. Subjects were also tested for glucose tolerance and insulin sensitivity, and dorsal and ventral striatal tissue was assayed ex vivo for markers of dopaminergic transmission. Obese KO rats learned the 5CSRTT at a slower rate compared to WT rats, in a manner suggestive of mild attentional impairment. However, task performance at baseline and after HFD intake was similar to that of WT controls. HFD intake reduced omissions across all subjects, whereas amphetamine challenge revealed a prominent genotype effect on 5CSRTT performance, with potentiated levels of impulsive responding and faster response times in KO rats compared to WT animals. Effects of amphetamine on other variables were similar between genotypes. Notably, the expression of striatal dopaminergic markers was unchanged in KO rats, and neither chronic food restriction nor HFD intake altered the impairments in glucose or insulin metabolism previously reported in these animals. These data suggest that leptin deficiency enhances impulsive action under conditions of dopaminergic challenge, yet this seems independent of overt changes in the expression of post-synaptic markers of dopamine signalling in striatal regions. PMID- 29601832 TI - Antidepressant effects of acupoint stimulation and fluoxetine by increasing dendritic arborization and spine density in CA1 hippocampal neurons of socially isolated rats. AB - Given the importance of depression and the adverse effects of conventional treatment, it is necessary to seek complementary therapies. In a rat model of depression, this study aimed to assess the behavioral and morphological effects of embedding absorbable thread in acupoints (acu-catgut), and compare the results to those of fluoxetine treatment and the corresponding control groups. Therefore, depressive-like behavior was evaluated with the forced swimming test, and dendritic morphology (in the CA1 hippocampal region) with the Golgi-Cox technique and Sholl analysis. After weaning, male Sprague-Dawley rats were housed in social isolation for 8 weeks to induce depressive-like behavior. They were then given a 21-day treatment by stimulating acupoints with acu-catgut (AC) or fluoxetine (FX) (2 mg/kg). Rats were divided into six groups: Control (socially housed), social isolation (SI), SI + AC, SI + Sham (sham embedding of thread), SI + FX and SI + VH (vehicle). Compared to fluoxetine, acu-catgut treatment was more effective in reversing depressive-like behavior elicited by SI. The SI-induced reduction in dendritic length and spine density in hippocampal CA1 pyramidal neurons was attenuated after prolonged treatment with acu-catgut or fluoxetine. Hence, both treatments proved capable of reversing depressive-like alterations caused by SI, likely due to dendritic remodeling in the hippocampus. PMID- 29601834 TI - Node balanced steady states: Unifying and generalizing complex and detailed balanced steady states. AB - We introduce a unifying and generalizing framework for complex and detailed balanced steady states in chemical reaction network theory. To this end, we generalize the graph commonly used to represent a reaction network. Specifically, we introduce a graph, called a reaction graph, that has one edge for each reaction but potentially multiple nodes for each complex. A special class of steady states, called node balanced steady states, is naturally associated with such a reaction graph. We show that complex and detailed balanced steady states are special cases of node balanced steady states by choosing appropriate reaction graphs. Further, we show that node balanced steady states have properties analogous to complex balanced steady states, such as uniqueness and asymptotic stability in each stoichiometric compatibility class. Moreover, we associate an integer, called the deficiency, to a reaction graph that gives the number of independent relations in the reaction rate constants that need to be satisfied for a positive node balanced steady state to exist. The set of reaction graphs (modulo isomorphism) is equipped with a partial order that has the complex balanced reaction graph as minimal element. We relate this order to the deficiency and to the set of reaction rate constants for which a positive node balanced steady state exists. PMID- 29601833 TI - Modelling leptospirosis in livestock. AB - New Zealand has one of the highest (per capita) incidences of human leptospirosis in the world. It is the highest occurring occupational disease in New Zealand, often transmitted from livestock such as deer, sheep and cattle to humans. A cyclical model, showing the dynamics of infection of leptospirosis in farmed livestock in New Zealand, is presented. The limit cycle, bifurcation diagram and quasi-R0 value of the system are determined. Leptospire death rate is used as a control parameter. Previously published parameter values are used in a case study to produce figures demonstrating analytical results. The model is used to predict conditions under which the infection will persist in the population. PMID- 29601835 TI - Photoacoustic imaging of synovial tissue hypoxia in experimental post-traumatic osteoarthritis. AB - OBJECTIVES: This pilot study aimed to investigate the feasibility of non invasively assessing synovial tissue hypoxia in vivo using photoacoustic (PA) imaging in a post-traumatic osteoarthritis model and explore its correlation with OA severity. METHODS: The three-dimensional vasculature structure and oxygenation level of synovial tissues of destabilization of the medial meniscus (DMM)-induced osteoarthritis (OA) mice were longitudinally monitored using PA imaging. Vascular volume/tissue volume (%) and tissue oxygen saturation (sO2) were validated against results obtained by established Power Doppler (PD) imaging and dynamic changes of inhaled O2 concentration respectively. PA changes were correlated with the histological grading of cartilage damages. RESULTS: PA-measurements of vascularity and sO2 demonstrated a strong correlation with localized blood flow detected by PD imaging (r = 0.506, p < 0.001) and inhaled O2 concentration. DMM knees exhibited much more vascularity in synovial tissue at 4 months after surgery (median 11.3%, IQR: 10.7-15.5%) than the intact knees at time zero (median:5.1%, IQR:3.8-6.8%, p < 0.001) as well as the sham-operated knees (median: 4%, IQR: 3.75-5.45%, p = 0.017). Paradoxically, synovial tissue sO2 was significantly lower in DDM knees (median: 37.7%, IQR: 36.4-40.6%) than both the intact (47.1%, IQR: 41.9-49.8% p = 0.001) and sham-operated knees (45.1% IQR: 45.1-52.4%, p = 0.017). The PA-detected synovial tissue hypoxia correlated with the severity of cartilage loss in DMM mice (rho = -0.597, p = 0.031). CONCLUSION: Here, we demonstrated PA imaging can be implemented for non-invasive imaging of the synovial tissue. Under PA imaging, synovitis in OA was characterized by increased angiogenesis and synovial tissue hypoxia; the latter was associated with the severity of OA. PMID- 29601836 TI - Unplanned Emergency Department Visits and Hospital Admissions Following Ureteroscopy: Do Ureteral Stents Make a Difference? AB - OBJECTIVE: To evaluate unplanned medical visits within the early postoperative period after ureteroscopy in patients with and without ureteral stent placement. MATERIALS AND METHODS: We identified all ureteroscopic procedures for urinary stone disease in the California Office of Statewide Health Planning and Development database from 2010 to 2012. The primary outcome was any emergency department visit or inpatient hospital admission in the first 7 days following ureteroscopy. Patients were subcategorized by type of ureteroscopy (ie, laser lithotripsy vs basket retrieval) and were analyzed for significant differences between stented and unstented patients. Multivariable logistic regression was performed to determine if ureteral stent placement was independently associated with unplanned visits. RESULTS: Our analytic cohort included 16,060 patients undergoing 17,716 ureteroscopy procedures. A ureteral stent was placed in 86.2% of patients undergoing laser lithotripsy and in 70.5% of patients receiving basket retrieval. In the 7 days following ureteroscopy, 6.6% of patients were seen in the emergency department and 2.2% of patients were admitted to a hospital. In a fully adjusted model, the utilization of a ureteral stent was not associated with emergency department visits or inpatient admissions. CONCLUSION: Ureteral stent placement during ureteroscopy is not associated with an increased odds of emergency department visits and inpatient admissions in the early postoperative period.

Developing a new biopharmaceutical drug product for the Japanese market is a top business priority for global pharmaceutical companies while aligning with ethical drivers to treat more patients in need. Understanding Japan-specific key regulatory requirements is essential to achieve successful approvals. Understanding the full context of Japan-specific regulatory requirements/expectations is challenging to global pharmaceutical companies due to differences in language and culture. This article summarizes key Japan-specific regulatory aspects/requirements/expectations applicable to new drug development, approval, and postapproval phases. Formulation excipients should meet Japan compendial requirements with respect to the type of excipient, excipient grade, and excipient concentration. Preclinical safety assessments needed to support clinical phases I, II, and III development are summarized. Japanese regulatory authorities have taken appropriate steps to consider foreign clinical data, thereby enabling accelerated drug development and approval in Japan. Other important topics summarized in this article include: Japan new drug application specific bracketing strategies for critical and noncritical aspects of the manufacturing process, regulatory requirements related to stability studies, release specifications and testing methods, standard processes involved in pre and postapproval inspections, management of postapproval changes, and Japan regulatory authority's consultation services available to global pharmaceutical companies. PMID- 29601840 TI - Protein Nanoparticles Promote Microparticle Formation in Intravenous Immunoglobulin Solutions During Freeze-Thawing and Agitation Stresses. AB - In this study, we investigated the potential roles of nanoparticles (<100 nm) and submicron (100-1000 nm) particles in the formation of microparticles (>1000 nm) in protein formulations under some pharmaceutically relevant stress conditions. Exposure of intravenous immunoglobulin solutions to the interface-associated stresses of freeze-thawing or agitation resulted in relatively large increases in microparticle concentrations, which depended directly on the levels of pre existing nano- and submicron particles. Thus, agglomeration of nanoparticles and submicron particles appears to play a role in microparticle formation under these stresses. In contrast, increases in microparticle concentrations during quiescent incubation at elevated temperatures were independent of the initial nano- and submicron particle concentrations in solution. PMID- 29601841 TI - Intratumoral and peritumoral lymphovascular invasion detected by D2-40 immunohistochemistry correlates with metastasis in primary cutaneous Merkel cell carcinoma. AB - Primary cutaneous Merkel cell carcinoma (MCC) is an aggressive neuroendocrine malignancy in which lymphovascular invasion (LVI) correlates with more aggressive phenotype. The prognostic significance of LVI detected by D2-40 immunohistochemistry (IHC) in MCC remains controversial. We aimed to determine how LVI detected by D2-40 IHC compares with LVI detected by hematoxylin and eosin (H&E) staining in predicting MCC metastasis. Clinical and histopathologic features of MCCs diagnosed and treated in 2002 to 2015 were assembled and included 58 MCC tumors from 58 patients. H&E-stained tissue sections and D2-40 IHC studies were reviewed. When LVI was present, the location (peritumoral or intratumoral) and the size of the largest invaded vessel were recorded. LVI findings by H&E staining and D2-40 IHC were compared with each other and with histologic features and clinical outcomes. H&E staining showed LVI in 37 of 58 cases; D2-40 IHC confirmed LVI in 30 of these cases but failed to confirm LVI in 7. D2-40 IHC also detected 14 cases of LVI not identified on H&E staining. Histologically, D2-40-detected LVI was associated with infiltrative growth pattern and nonbrisk lymphoid infiltrate (P = .005 and P = .055, respectively). There was a statistically significant difference between the frequency of detection of peritumoral LVI by H&E in comparison to D2-40 IHC (P = .0009). MCCs in which D2-40 IHC-detected both intratumoral and peritumoral LVI were typically larger than MCCs without (mean, 24.5 mm versus 17.3 mm; P = .03) and more frequently metastasized (87% versus 51%; P = .03). D2-40 IHC detection of both intratumoral and peritumoral LVI is associated with metastasis.

AB - Micropapillary urothelial carcinoma (MPUC) is a rare but an aggressive variant of urothelial carcinoma. MPUC has been shown to commonly exhibit ERBB2 amplification and HER2 protein overexpression, but the frequency and distribution of these findings within micropapillary (MP) and not otherwise specified (NOS) components of tumors with mixed histology have not been addressed. Therefore, we evaluated ERBB2 amplification and HER2 expression in 43 MPUC cases by fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC). Of the 35 tumors containing both MP and NOS components, ERBB2 amplification was present in both the MP and NOS components of 12 tumors (34.3%), in only the MP component of 11 tumors (31.4%), and exclusively in the NOS component of 4 tumors (11.4%). HER2 protein overexpression was significantly more commonly present in the MP component compared to the NOS component within the same tumor (68.6% versus 34.3%, P = .012). Overall, there was a moderately positive correlation between HER2 protein expression and ERBB2 amplification in both MP (rho = 0.59, P < .001) and NOS (rho = 0.70, P < .001) components. All MP/NOS areas with IHC score 3+ and none of MP/NOS areas with IHC score 0 were associated with ERBB2 amplification. We conclude that ERBB2 amplification and HER2 overexpression are preferentially but not exclusively identified in the MP component compared to the NOS component within the same tumor. Our findings identify the presence of intratumoral heterogeneity of ERBB2 amplification and HER2 expression in MPUC and provide grounds for further investigation into the mechanisms underlying the development of MPUC. PMID- 29601843 TI - Development and validation of rt-qpcr for vesicular stomatitis virus detection (Alagoas vesiculovirus). AB - Vesicular stomatitis is an infectious disease that occurs mainly in countries of the Western Hemisphere and affects cattle, swine and horses. The clinical symptoms in cattle and swine are similar to foot-and-mouth disease and include vesicular ulceration of the tongue and mouth. The disease requires a rapid and accurate differential diagnosis, aiming for immediate implementation of control measures. The objective of the present study was to develop and perform validation tests of multiplex RT-qPCR(s) for the detection of RNA from Alagoas vesiculovirus, considering the parameters of sensitivity and analytical specificity, analytical performance (repeatability and reproducibility criteria) and the uncertainty of the measurement. The threshold cycle values obtained in triplicate from each sample were evaluated by considering the variations between days, analysts and equipment in an analysis of variance aimed at determining the variances of repeatability and reproducibility. The results showed that RT-qPCRs had excellent sensitivity and specificity in the detection of RNA of the Alagoas vesiculovirus. The validation parameters showed low coefficients of variation and were equivalent to those found in other validation studies, indicating that the tests presented excellent repeatability and reproducibility. PMID- 29601845 TI - The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes. AB - Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain relatively poorly understood. Endogenous circoviral elements (CVe) are DNA sequences derived from circoviruses that occur in vertebrate genomes. CVe are a useful source of information about the biology and evolution of circoviruses. In this study, we screened 362 vertebrate genome assemblies in silico to generate a catalog of CVe loci. We identified a total of 179 CVe sequences, most of which have not been reported previously. We show that these CVe loci reflect at least 19 distinct germline integration events. We determine the structure of CVe loci, identifying some that show evidence of potential functionalization. We also identify orthologous copies of CVe in snakes, fish, birds, and mammals, allowing us to add new calibrations to the timeline of circovirus evolution. Finally, we observed that some ancient CVe group robustly with contemporary circoviruses in phylogenies, with all sequences within these groups being derived from the same host class or order, implying a hitherto underappreciated stability in circovirus-host relationships. The openly available dataset constructed in this investigation provides new insights into circovirus evolution, and can be used to facilitate further studies of circoviruses and CVe. PMID- 29601847 TI - Repeated peripheral administration of lipidized prolactin-releasing peptide analog induces c-fos and FosB expression in neurons of dorsomedial hypothalamic nucleus in male C57 mice. AB - Previous studies indicate that hypothalamic prolactin-releasing peptide (PrRP), signaling via GPR10 and neuropeptide FF2 receptor, is involved in energy homeostasis, stress responses, and cardiovascular regulation. Energy homeostasis depends on the balance between food intake regulation and energy expenditure, in which the hypothalamus plays a key role. The lipidization of PrRP31 with palmitoyl acid allows it to produce its anorexigenic effect after repeated peripheral administration and to reduce body weight and improve metabolic parameters in diet-induced obese (DIO) mice. The aim of this study was to reveal the transient and long-lasting changes in neuronal activity via c-Fos and FosB immunohistochemistry in brain nuclei related to food intake regulation and energy homeostasis during the first days of treatment with a newly designed lipidized analog of PrRP31 (palm11-PrRP31) with promising antiobesity effects. The data revealed that the anorexigenic effect of repeated application of palm11-PrRP31 was associated with delayed but gradually significantly reduced cumulative food intake in mice as well as with a significant reduction in their body weight. Moreover, while the repeated application of palm11-PrRP31 was associated with a significant reduction in acute cell activity in the paraventricular hypothalamic nucleus (PVN) and nucleus of the solitary tract (NTS) compare to its acute treatment, both acute and long-lasting cell activity in the dorsomedial hypothalamic nucleus (DMN) were increased. The data indicate that DMN neurons might be tonically activated after repeated administration of lipidized PrRP analogs that may be associated with the process of long-term adaptation to modified energy homeostasis. PMID- 29601846 TI - Burden of caregiving after a child's in-hospital cardiac arrest. AB - OBJECTIVE: To describe caregiver burden among those whose children survive in hospital cardiac arrest and have high risk of neurologic disability, and explore factors associated with burden during the first year post-arrest. METHODS: The study is a secondary analysis of the Therapeutic Hypothermia after Paediatric Cardiac Arrest In-Hospital (THAPCA-IH) trial. 329 children who had an in-hospital cardiac arrest, chest compressions for >2 min, and mechanical ventilation after return of circulation were recruited to THAPCA-IH. Of these, 155 survived to one year, and caregivers of 138 were assessed for burden. Caregiver burden was assessed at baseline, and 3 and 12 months post-arrest using the Infant Toddler Quality of Life Questionnaire for children <5 years old and the Child Health Questionnaire for children >5 years. Child functioning was assessed using the Vineland Adaptive Behaviour Scales Second Edition (VABS-II), the Paediatric Overall Performance Category (POPC) and Paediatric Cerebral Performance Category (PCPC) scales, and caregiver perception of global functioning. RESULTS: Of 138 children, 77 (55.8%) were male, 77 (55.8%) were white, and 109 (79.0%) were <5 years old at the time of arrest. Caregiver burden was greater than reference norms at all time points. Worse POPC, PCPC and VABS-II scores at 3 months post arrest were associated with greater caregiver burden at 12 months. Worse global functioning at 3 months was associated with greater burden at 12 months for children <5 years. CONCLUSIONS: Caregiver burden is substantial during the first year after paediatric in-hospital cardiac arrest, and associated with the extent of the child's neurobehavioural dysfunction. PMID- 29601848 TI - Food safety using NMR-based metabolomics: Assessment of the Atlantic bluefin tuna, Thunnus thynnus, from the Mediterranean Sea. AB - Seafood is a valuable component of human diet because of its nutritional properties. The Atlantic bluefin tuna Thunnus thynnus is a scombroid fish highly appreciated as seafood worldwide. Being a top pelagic predator, concerns have been raised over human health risks due to its consumption. Therefore, herein it was comprehensively evaluated the health status and potential metabolite shifts between sexes of bluefin tuna from the Mediterranean Sea, proved to bioaccumulate environmental obesogens, namely polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) at hepatic level. To this aim, nuclear magnetic resonance (NMR)-based metabolomics was applied on liver of post-spawning tuna. Findings from this study pointed out that hepatic bioaccumulation of PCBs and OCPs induced differential metabolic disturbances between sexes, attributable to the reproductive stage at which tuna were caught. Alterations were mainly found in energy-producing metabolic pathways (with changes in acetate, acetoacetate, malonate, and lactate), amino acid (with changes in BCAA, alanine, sarcosine, and tyrosine), and lipid (with changes in choline and phosphocholine) metabolism, with activation of fatty acids biosynthesis and ketogenesis in male tuna. Overall, according to the current European legislation on maximum levels of contaminants in seafood, the consumption of bluefin tuna does not represent a risk for human health. PMID- 29601849 TI - Tolerance response and metabolism of acetic acid by biodetoxification fungus Amorphotheca resinae ZN1. AB - Removal of acetic acid from pretreated lignocellulose biomass is an important step for the consequent fermentation on production of cellulosic ethanol and biobased chemicals. This study elucidates the biological metabolism and tolerance response of acetic acid by a widely used biodetoxification fungus Amorphotheca resinae ZN1. Acetic acid is consumed as a prior substrate to glucose and xylose by A. resinae ZN1, and the consumption is highly accelerated by solid state culture. Acetic acid is metabolized through the tricarboxylic acid (TCA) cycle when glucose exists in the medium, while through the two cycles of both the TCA cycle and glyoxylate cycle when there is no sugar in the medium. The tolerance response of A. resinae ZN1 to acetic acid includes various biological processes such as activation of ions transport, increase in amino acids uptake and biosynthesis, as well as induction of ergosterol biosynthesis and ATP generation. The study provided important basis for the future biodetoxification strain modification for enhanced acetic acid removal. PMID- 29601850 TI - miR-326 regulates HbF synthesis by targeting EKLF in human erythroid cells. AB - Haploinsufficiency of erythroid Kruppel-like factor (EKLF/KLF1) has been shown recently to ameliorate the clinical severity of beta-thalassemia by increased expression levels of fetal hemoglobin (HbF). The underlying mechanisms for role of EKLF in regulating HbF are of great interest but remain incompletely understood. In this study, we used a combination of in silico, in vitro, and in vivo approaches to identify microRNAs (miRs) involved in EKLF regulation and to validate the role of miR-326 in HbF modification. We found that miR-326 suppresses EKLF expression directly by targeting its 3' untranslated region. miR 326 overexpression in K562 cells or CD34+ hematopoietic progenitor cells resulted in reduced EKLF protein levels and was associated with elevated expression of gamma-globin, whereas inhibition of physiological miR-326 levels increased EKLF and thus reduced gamma-globin expression. Moreover, miR-326 expression is positively correlated with HbF levels in beta-thalassemia patients. Our results suggest that miR-326 plays a key role in regulating EKLF expression and in modifying the HbF level, which may provide a new strategy for activating HbF in individuals with beta-thalassemia or sickle cell disease. PMID- 29601851 TI - MicroRNA-155 expression and function in AML: An evolving paradigm. AB - Acute myeloid leukemia (AML) arises when immature myeloid blast cells acquire multiple, recurrent genetic and epigenetic changes that result in dysregulated proliferation. Acute leukemia is the most common form of pediatric cancer, with AML accounting for ~20% of all leukemias in children. The genomic aberrations that drive AML inhibit myeloid differentiation and activate signal transduction pathways that drive proliferation. MicroRNAs, a class of small (~22 nucleotide) noncoding RNAs that posttranscriptionally suppress the expression of specifically targeted transcripts, are also frequently dysregulated in AML, which may prove useful for the purposes of disease classification, prognosis, and future therapeutic approaches. MicroRNA expression profiles are associated with patient prognosis and responses to standard chemotherapy, including predicting therapy resistance in AML. miR-155 is the primary focus of this review because it has been repeatedly associated with poorer survival across multiple cohorts of adult and pediatric AML. We discuss some novel features of miR-155 expression in AML, in particular how the levels of expression can critically influence function. Understanding the role of microRNAs in AML and the ways in which microRNA expression influences AML biology is one means to develop novel and more targeted therapies. PMID- 29601852 TI - Gene variants in the NF-KB pathway (NFKB1, NFKBIA, NFKBIZ) and their association with type 2 diabetes and impaired renal function. AB - The NF-kappaB pathway might play a role in the pathogenesis of renal disease and type 2 diabetes (T2DM). Our aim was to determine whether common polymorphisms in NF-kappaB genes were associated with impaired renal function and T2DM in a cohort of healthy elderly individuals. We studied 487 individuals, all Caucasian and aged 65-85 years. A total of 104 (21%) had impaired renal function (estimated glomerular filtration rate, eGFR < 60) and 146 (30%) were classified as diabetics. The genotypes of 4 common variants were determined through PCR-RFLP or fluorescent capillary electrophoresis. The NFKB1 variants were significantly associated with T2DM: rs7667496 p = 0.01, OR = 1.68; and rs28362491 p = 0.02, OR = 1.67. They remained significantly associated in a multiple logistic regression with age, gender, hypertension, body mass index, and cholesterol. There was a trend toward the association of these variants with eGFR < 60. The two NFKB1 variants were in linkage disequilibrium (D' = -0.86), and homozygous for the two non-risk alleles (rs7667496 CC + rs28362491 II), were significantly more common in the non-diabetics (p = 0.02). In our cohort the NFKB1 variation was an independent risk factor for developing T2DM. Additional studies to confirm this association are of special interest, as well as studies to give a functional explanation to the genetic association. PMID- 29601853 TI - Predictors of cognitive impairment assessed by Mini Mental State Examination in community-dwelling older adults: relevance of the step test. AB - BACKGROUND: Several predictors of cognitive impairment assessed by Mini Mental State Examination (MMSE) have previously been identified. However, which predictors are the most relevant and what is their effect on MMSE categories remains unclear. METHODS: Cross-sectional and longitudinal study using data from 1116 older adults (72.6 +/- 5.6 years, 579 female), 350 of whom were followed for 7 years. At baseline, the following variables were collected: personal data, marital status, occupation, anthropometric measures, risk factors, previous cardiovascular events, self-rated health and physical activity during the last week. Furthermore, routine laboratory tests, abdominal echography and a step test (with measurement of the time needed to ascend and descend two steps 20 times) were performed. The associations of these variables with cross-sectional cognitive deficit (MMSE < 24) and longitudinal cognitive decline (decrease of MMSE score over 7 years of follow-up) were investigated using logistic regression models. RESULTS: Cross-sectional cognitive deficit was independently associated with school education <= 5 years, prolonged step test duration, having been blue collar or housewife (P <= 0.0001 for all) and, with lower significance, with advanced age, previous stroke and poor recent physical activity (P < 0.05). Longitudinal cognitive decline was mainly associated with step test duration (P = 0.0001) and diastolic blood pressure (P = 0.0002). The MMSE categories mostly associated with step test duration were orientation, attention, calculation and language, while memory appeared to be poorly or not affected. CONCLUSIONS: In our cohort of older adults, step test duration was the most relevant predictor of cognitive impairment. PMID- 29601854 TI - Patients with core antibody positive and surface antigen negative Hepatitis B (anti-HBc+, HBsAg-) on anti-TNF therapy have a low rate of reactivation. AB - Anti-TNF agents are widely used to treat immune-mediated disorders. Reactivation of Hepatitis B virus (HBV) is associated with immunosuppressive agents and biologics such as anti-TNF. There are limited data and differing guidelines for patients with negative hepatitis B surface antigen (HBsAg-) but positive antibody to hepatitis B core antigen (anti-HBc+) on anti-TNF with regards to outcomes and need for anti-viral prophylaxis. We examined the prevalence of HBV reactivation in a single-center retrospective cohort study of 120 HBsAg-, anti-HBc+ patients on anti-TNF, totaling 346.6 patient years. One patient (0.8%) who had a detectable VL (<20 IU) prior to starting anti-TNF had reactivation of HBV with sero-conversion to positive HBsAg. Three patients (2.5%) had undetectable HBV VL prior to anti-TNF and developed detectable VL while on anti-TNF. In conclusion, there was a low rate of HBV reactivation or development of detectable HBV DNA in HBsAg-, anti-HBc+ patients on anti-TNF. PMID- 29601855 TI - EGR-1 Expression in Catecholamine-synthesizing Neurons Reflects Auditory Learning and Correlates with Responses in Auditory Processing Areas. AB - Distinguishing between familiar and unfamiliar individuals is an important task that shapes the expression of social behavior. As such, identifying the neural populations involved in processing and learning the sensory attributes of individuals is important for understanding mechanisms of behavior. Catecholamine synthesizing neurons have been implicated in sensory processing, but relatively little is known about their contribution to auditory learning and processing across various vertebrate taxa. Here we investigated the extent to which immediate early gene expression in catecholaminergic circuitry reflects information about the familiarity of social signals and predicts immediate early gene expression in sensory processing areas in songbirds. We found that male zebra finches readily learned to differentiate between familiar and unfamiliar acoustic signals ('songs') and that playback of familiar songs led to fewer catecholaminergic neurons in the locus coeruleus (but not in the ventral tegmental area, substantia nigra, or periaqueductal gray) expressing the immediate early gene, EGR-1, than playback of unfamiliar songs. The pattern of EGR-1 expression in the locus coeruleus was similar to that observed in two auditory processing areas implicated in auditory learning and memory, namely the caudomedial nidopallium (NCM) and the caudal medial mesopallium (CMM), suggesting a contribution of catecholamines to sensory processing. Consistent with this, the pattern of catecholaminergic innervation onto auditory neurons co-varied with the degree to which song playback affected the relative intensity of EGR-1 expression. Together, our data support the contention that catecholamines like norepinephrine contribute to social recognition and the processing of social information. PMID- 29601857 TI - Predicting Ion Mobility-Mass Spectrometry trends of polymers using the concept of apparent densities. AB - Ion Mobility (IM) coupled to Mass Spectrometry (MS) has been used for several decades, bringing a fast separation dimension to the MS detection. IM-MS is a convenient tool for structural elucidation. The folding of macromolecules is often assessed with the support of computational chemistry. However, this strategy is strongly dependent on computational initial guesses. Here, we propose the analysis of the Collision Cross-Section (CCS) trends of synthetic homopolymers based on a fitting method which does not rely on computational chemistry a prioris of the three-dimensional structures. The CCS trends were evaluated as a function of the polymer chain length and the charge state. This method is also applicable to mobility trends. It leads to two parameters containing all information available through IM(-MS) measurements. One parameter can be interpreted as an apparent density. The second parameter is related to the shape of the ions and leads us to introduce the concept of trends with constant apparent density. Based on the two fitting parameters, a method for IM trend predictions is elaborated. Experimental deviations from the predictions facilitate detecting structural rearrangements and three-dimensional structure differences of the cationized polymer ions. This leads for instance to an easy identification and prediction of the presence of different polymer topologies in complex polymer mixtures. The classification of predicted trends could as well allow for software-assisted data processing. Finally, we suggest the link between the CCS trends of homopolymers and those obtained from (monodisperse) biomolecules to interpret potential folding differences during IM-MS studies.

AB - Cyanobacteria are photosynthetic microorganisms whose metabolism can be modified through genetic engineering for production of a wide variety of molecules directly from CO2, light, and nutrients. Diverse molecules have been produced in small quantities by engineered cyanobacteria to demonstrate the feasibility of photosynthetic biorefineries. Consequently, there is interest in engineering these microorganisms to increase titer and productivity to meet industrial metrics. Unfortunately, differing experimental conditions and cultivation techniques confound comparisons of strains and metabolic engineering strategies. In this work, we discuss the factors governing photoautotrophic growth and demonstrate nutritionally replete conditions in which a model cyanobacterium can be grown to stationary phase with light as the sole limiting substrate. We introduce a mathematical framework for understanding the dynamics of growth and product secretion in light-limited cyanobacterial cultures. Using this framework, we demonstrate how cyanobacterial growth in differing experimental systems can be easily scaled by the volumetric photon delivery rate using the model organisms Synechococcus sp. strain PCC7002 and Synechococcus elongatus strain UTEX2973. We use this framework to predict scaled up growth and product secretion in 1L photobioreactors of two strains of Synechococcus PCC7002 engineered for production of l-lactate or L-lysine. The analytical framework developed in this work serves as a guide for future metabolic engineering studies of cyanobacteria to allow better comparison of experiments performed in different experimental systems and to further investigate the dynamics of growth and product secretion. PMID- 29601858 TI - Applications of Gene Editing Technologies to Cellular Therapies. AB - Hematologic malignancies are characterized by genetic heterogeneity, making classic gene therapy with a goal of correcting 1 genetic defect ineffective in many of these diseases. Despite initial tribulations, gene therapy, as a field, has grown by leaps and bounds with the recent development of gene editing techniques including zinc finger nucleases, transcription activator-like effector nucleases, and clustered regularly interspaced short palindromic repeat (CRISPR) sequences and CRISPR-associated protein-9 (Cas9) nuclease or CRISPR/Cas9. These novel technologies have been applied to efficiently and specifically modify genetic information in target and effector cells. In particular, CRISPR/Cas9 technology has been applied to various hematologic malignancies and has also been used to modify and improve chimeric antigen receptor-modified T cells for the purpose of providing effective cellular therapies. Although gene editing is in its infancy in malignant hematologic diseases, there is much room for growth and application in the future. PMID- 29601859 TI - Perfluoroalkylated substances (PFAS) affect neither estrogen and androgen receptor activity nor steroidogenesis in human cells in vitro. AB - The perfluoroalkylated substances (PFAS) perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are used for the fabrication of water- and dirt repellent surfaces. The use of PFOS and PFOA was restricted due to their reprotoxic properties and their environmental persistence. Therefore, industry switches to alternative PFAS, however, in contrast to PFOA and PFOS only few toxicological data are available for their substitutes. The molecular mechanism(s) underlying reproductive toxicity of PFOA and PFOS are largely unknown. Here, the endocrine properties of PFOA, PFOS, and of six substitutes including perfluorohexanesulfonic acid (PFHxS), perfluorobutanesulfonic acid (PFBS), perfluorohexanoic acid (PFHxA), perfluorobutanoic acid (PFBA), ammonium perfluoro(2-methyl-3-oxahexanoate) (PMOH), and 3H-perfluoro-3-[(3-methoxypropoxy) propanoic acid] (PMPP) were examined in vitro by using human cell lines such as MCF-7, H295R, LNCaP and MDA-kb2. PFOA, PFOS and PMOH enhanced 17beta-estradiol stimulated estrogen receptor beta activity, and PFOS, PMOH, PFHxA and PFBA enhanced dihydrotestosterone-stimulated androgen receptor activity. In the H295R steroidogenesis assay, PFOA and PFOS slightly enhanced estrone secretion, and progesterone secretion was marginally increased by PFOA. All these effects were only observed at concentrations above 10 MUM, and none of the PFAS displayed any effect on any of the molecular endocrine endpoints at concentrations of 10 MUM or below. Thus, as the blood serum concentrations of the different PFAS in the general Western population are in the range of 10 nM or below, the results suggest that PFAS might not exert endocrine effects in humans at exposure relevant concentrations according to the molecular endpoints examined in this study. PMID- 29601860 TI - Urinary excretion of heptanones, heptanoles and 2,5-heptanedione after controlled acute exposure of volunteers to n-heptane. AB - A lack of well-established parameters and assessment values currently impairs biomonitoring of n-heptane exposure. Using controlled inhalation experiments, we collected information on urinary n-heptane metabolite concentrations and the time course of metabolite excretion. Relationships between external and internal exposure were analysed to investigate the suitability of selected metabolites to reflect n-heptane uptake. Twenty healthy, non-smoking males (aged 19-38 years, median 25.5) were exposed for 3 h to 167, 333 and 500 ppm n-heptane, each. Spot urine samples of the volunteers, collected before exposure and during the following 24 h, were analysed for heptane-2-one, 3-one, 4-one, 2,5-dione, 1-ol, 2 ol, 3-ol, and 4-ol using headspace solid phase dynamic extraction gas chromatography/mass spectrometry (HS-SPDE-GC/MS). Starting from median pre exposure concentrations between <0.5 (3-one) and 82.9 MUg/L (4-one), exposure increased the concentrations for all parameters except for 4-one. Median post exposure concentrations ranged up to 840.4 MUg/L (2-ol) and decreased with half lifes <3 h after exposure. Non-parametric correlation analyses (n = 47, p < 0.05) revealed weak to moderate associations of volume related metabolite excretion with external exposure for 2-one, 3-one and 2,5-dione (R = 0.332-0.753). Heptanol excretion was moderately associated with exposure (R >= 0.509) only after creatinine adjustment. Lacking association with external exposure impedes the use of 4-one as heptane biomarker, whereas 2-ol and 3-ol turned out to be sensitive indicators of exposure if creatinine correction is applied. By providing fundamental data on a panel of eight potential heptane metabolites, our study can help to promote biological monitoring of n-heptane exposure. PMID- 29601862 TI - Phagocytes as central players in the defence against invasive fungal infection. AB - Fungal pathogens cause severe and life-threatening infections worldwide. The majority of invasive infections occurs in immunocompromised patients and is based on acquired as well as congenital defects of innate and adaptive immune responses. In many cases, these defects affect phagocyte functions. Consequently, professional phagocytes - mainly monocytes, macrophages, dendritic cells and polymorphonuclear neutrophilic granulocytes - have been shown to act as central players in initiating and modulating antifungal immune responses as well as elimination of fungal pathogens. In this review we will summarize our current understanding on the role of these professional phagocytes in invasive fungal infection to emphasize two important aspects. (i) Analyses on the interaction between fungi and phagocytes have contributed to significant new insights into phagocyte biology. Important examples for this include the identification of pattern recognition receptors for beta-glucan, a major cell wall component of many fungal pathogens, as well as the identification of genetic polymorphisms that determine individual host responses towards invading fungi. (ii) At the same time it was shown that fungal pathogens have evolved sophisticated mechanisms to counteract the attack of professional phagocytes. These mechanisms range from complete mechanical destruction of phagocytes to exquisite adaptation of some fungi to the hostile intracellular environment, enabling them to grow and replicate inside professional phagocytes. PMID- 29601861 TI - Neutrophil extracellular traps in fungal infection. AB - Fungal infections are a continuously increasing problem in modern health care. Understanding the complex biology of the emerging pathogens and unraveling the mechanisms of host defense may form the basis for the development of more efficient diagnostic and therapeutic tools. Neutrophils play a pivotal role in the defense against fungal pathogens. These phagocytic hunters migrate towards invading fungal microorganisms and eradicate them by phagocytosis, oxidative burst and release of neutrophil extracellular traps (NETs). In the last decade, the process of NET formation has received unparalleled attention, with numerous studies revealing the relevance of this neutrophil function for control of various mycoses. Here, we describe NET formation and summarize its role as part of the innate immune defense against fungal pathogens. We highlight factors influencing the formation of these structures and molecular mechanisms employed by fungi to impair the formation of NETs or subvert their antifungal effects. PMID- 29601863 TI - Culturing functional pancreatic islets on alpha5-laminins and curative transplantation to diabetic mice. AB - The efficacy of islet transplantation for diabetes treatment suffers from lack of cadaver-derived islets, islet necrosis and long transfer times prior to transplantation. Here, we developed a method for culturing mouse and human islets in vitro on alpha5-laminins, which are natural components of islet basement membranes. Adhering islets spread to form layers of 1-3 cells in thickness and remained normoxic and functional for at least 7 days in culture. In contrast, spherical islets kept in suspension developed hypoxia and central necrosis within 16 h. Transplantation of 110-150 mouse islets cultured on alpha5-laminin-coated polydimethylsiloxane membranes for 3-7 days normalized blood glucose already within 3 days in mice with streptozotocin-induced diabetes. RNA-sequencing of isolated and cultured mouse islets provided further evidence for the adhesion and spreading achieved with alpha5-laminin. Our results suggest that use of such in vitro expanded islets may significantly enhance the efficacy of islet transplantation treatment for diabetes. PMID- 29601864 TI - TMEM2: A missing link in hyaluronan catabolism identified? AB - Hyaluronan (HA) is a glycosaminoglycan (GAG) composed of repeating disaccharide units of glucuronic acid and N-acetylglucosamine. HA is an extremely long, unbranched polymer, which often exceeds 106 Da and sometimes reaches 107 Da. A feature that epitomizes HA is its rapid turnover; one-third of the total body HA is turned over daily. The current model of HA catabolism postulates that high molecular weight HA in the extracellular space is first cleaved into smaller fragments by a hyaluronidase(s) that resides at the cell surface, followed by internalization of fragments and their degradation into monosaccharides in lysosomes. Over the last decade, considerable research has shown that the HYAL family of hyaluronidases plays significant roles in HA catabolism. Nonetheless, the identity of a hyaluronidase responsible for the initial step of HA cleavage on the cell surface remains elusive, as biochemical and enzymological properties of HYAL proteins are not entirely consistent with those expected of cell surface hyaluronidases. Recent identification of transmembrane 2 (TMEM2) as a cell surface protein that possesses potent hyaluronidase activity suggests that it may be the "missing" cell surface hyaluronidase, and that novel models of HA catabolism should include this protein. PMID- 29601865 TI - Water-fat separation incorporating spatial smoothing is robust to noise. AB - PURPOSE: To develop and evaluate a noise-robust method for reconstruction of water and fat images for spoiled gradient multi-echo sequences. METHODS: The proposed method performs water-fat separation by using a graph cut to minimize an energy function consisting of unary and binary terms. Spatial smoothing is incorporated to increase robustness to noise. The graph cut can fail to find a solution covering the entire image, in which case the relative weighting of the unary term is iteratively increased until a complete solution is found. The proposed method was compared to two previously published methods. Reconstructions were performed on 16 cases taken from the 2012 ISMRM water-fat reconstruction challenge dataset, for which reference reconstructions were provided. Robustness towards noise was evaluated by reconstructing images with different levels of noise added. The percentage of water-fat swaps were calculated to measure performance. RESULTS: At low noise levels the proposed method produced similar results to one of the previously published methods, while outperforming the other. The proposed method significantly outperformed both of the previously published methods at moderate and high noise levels. CONCLUSION: By incorporating spatial smoothing, an increased robustness towards noise is achieved when performing water-fat reconstruction of spoiled gradient multi-echo sequences.

AB - Here, we propose the extension of the quality-by-design (QbD) concept to also fit the early development phases of pharmaceuticals by adding elements that are currently widely applied, but not yet included in the QbD model in a structured way. These are the introduction of a 'zero' preformulation phase (i.e., selection of drug substance, possible dosage forms and administration routes based on the evaluated therapeutic need); building in stakeholders' (industry, patient, and regulatory) requirements into the quality target product profile (QTTP); and the use of modern quality management tools during the composition and process design phase [collecting critical quality attributes (CQAs) and selection of CPPs) for (still laboratory-scale) design space (DS) development. Moreover, during industrial scale-up, CQAs (as well as critical process parameters; CPPs) can be changed; however, we recommend that the existing QbD elements are reconsidered and updated after this phase.

AB - This study aimed to elucidate the effect of Helicobacter pylori (H. pylori) and high salt diet on Trefoil factor 2 (TFF2) expression level of Mongolian gerbils (MGs) gastric mucosa. The results of H. pylori identification and histopathology showed that H. pylori infected MGs model was built successfully. According to the immunohistochemical staining results, 25% (4/16) of H. pylori infected MGs with high salt diet showed high TFF2 expression, which was significantly lower than H. pylori infection group 61% (11/18)(P = 0.045). The results suggested that High salt diet could down-regulated TFF2 expression level of MGs gastric mucosa induced by H. pylori infection.

AB - OBJECTIVE: This study was designed to investigate the impacts of Staphylococcus aureus isolated from sperm of male infertility patients, and explore the mechanism of the spermatozoa immobilization attributed to S. aureus. METHODS: S. aureus MJ015 and MJ163, the representative strains of immobilization positive and negative group respectively, were obtained from semen of infertile men. Computer aided sperm analysis (CASA) were performed to measure sperm motility. Transmission electron microscopy (TEM) was utilized to assess morphological alterations of spermatozoa. Two-dimensional gel electrophoresis (2-DE) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) were undertaken to analyse the difference between the secretory proteins of MJ015 and MJ163. RESULTS: A highly significant decline in motility of spermatozoa after incubating with cultured supernatant of MJ015 by sperm motility measurements, which was not observed when co-cultured with the supernatant of MJ163. TEM illustrated that the culture supernatant of MJ015 contributed to apparently ultrastructural impairment and inhibitory impacts on sperm motility. Various proteins expressed by two samples were identified. Data processing and database search preliminarily establish a link between four differential proteins and spermatozoal immobilization ability. CONCLUSIONS: Our data manifested that the clinical isolates of S. aureus have a key role on the motility and morphology of sperm. A better correlation between four identified differentially expressed proteins and the marked decline of the motility of spermatozoa was established. PMID- 29601870 TI - Anti-GM1 ganglioside antibodies modulate membrane-associated sphingomyelin metabolism by altering neutral sphingomyelinase activity. AB - Previous studies have shown that patients with Guillain-Barre syndrome express autoantibodies against ganglioside GM1 (GM1), although its pathogenic significance for the development of the disease remains to be elucidated. nSMase2 is the best characterized neutral sphingomyelinase (nSMase) found in neuronal cells. Activation of this enzyme leads to ceramide production, which is a known second messenger of the cell-death program in neuronal cells. We have explored the effects of anti-GM1 antibodies on sphingomyelin metabolism of PC12 cells stably transfected with human trk cDNA (PCtrk cells) by determining their effects on nSMase2 activity. The data we present here strongly suggest that anti-GM1 caused a significant change in sphingomyelin content of the membrane fraction in PCtrk cells. Both nSMase2 activity and the level of nSMase2 protein were significantly decreased by anti-GM1 treatment of PCtrk cells, while acidic SMase activities remained unchanged. Our results indicate, for the first time, that anti-GM1 may produce profound impacts on lipid metabolism in neuronal cell membranes. PMID- 29601869 TI - d-Serine administration affects nitric oxide synthase 1 adaptor protein and DISC1 expression in sex-specific manner. AB - Antipsychotic medications are inefficient at treating symptoms of schizophrenia (SCZ), and N-methyl d-aspartate receptor (NMDAR) agonists are potential therapeutic alternatives. As such, these agonists may act on different pathways and proteins altered in the brains of patients with SCZ than do antipsychotic medications. Here, we investigate the effects of administration of the antipsychotic haloperidol and NMDAR agonist d-serine on function and expression of three proteins that play significant roles in SCZ: nitric oxide synthase 1 adaptor protein (NOS1AP), dopamine D2 (D2) receptor, and disrupted in schizophrenia 1 (DISC1). We administered haloperidol or d-serine to male and female Sprague Dawley rats via intraperitoneal injection for 12 days and subsequently examined cortical expression of NOS1AP, D2 receptor, and DISC1. We found sex-specific effects of haloperidol and d-serine treatment on the expression of these proteins. Haloperidol significantly reduced expression of D2 receptor in male, but not female, rats. Conversely, d-serine reduced expression of NOS1AP in male rats and did not affect D2 receptor expression. d-serine treatment also reduced expression of DISC1 in male rats and increased DISC1 expression in female rats. As NOS1AP is overexpressed in the cortex of patients with SCZ and negatively regulates NMDAR signaling, we subsequently examined whether treatment with antipsychotics or NMDAR agonists can reverse the detrimental effects of NOS1AP overexpression in vitro as previously reported by our group. NOS1AP overexpression promotes reduced dendrite branching in vitro, and as such, we treated cortical neurons overexpressing NOS1AP with different antipsychotics (haloperidol, clozapine, fluphenazine) or d-serine for 24 h and determined the effects of these drugs on NOS1AP expression and dendrite branching. While antipsychotics did not affect NOS1AP protein expression or dendrite branching in vitro, d-serine reduced NOS1AP expression and rescued NOS1AP-mediated reductions in dendrite branching. Taken together, our data suggest that d-serine influences the function and expression of NOS1AP, D2 receptor, and DISC1 in a sex-specific manner and reverses the effects of NOS1AP overexpression on dendrite morphology. PMID- 29601871 TI - Molecular characterization and genetic diversity of avian paramyxovirus type 4 isolated in South Korea from 2013 to 2017. AB - In recent years, avian paramyxovirus type 4 (APMV-4) frequently isolated from wild and domestic bird populations particularly waterfowls worldwide. However, molecular characteristics and genetic diversity of APMV-4 are uncertain, owing to the limited availability of sequence information. A total of 11 APMV-4 strains from 9850 fecal, swab, and environmental samples were isolated during the surveillance program in wintering seasons of 2013-2017 in South Korea. We performed genetic characterization and phylogenetic analysis to investigate the genetic diversity and relatedness between isolates from the region. We report high APMV-4 genetic diversity (multiple genotypes and sub-genotypes) among wild bird and poultry populations in Korea and that the potential virus exchange occurs between neighboring countries via wild bird migration. Furthermore, our study results suggest the possibility of transcontinental transmission of APMV-4 between Asia and Europe. PMID- 29601872 TI - Spatiotemporal and demographic history of the HIV-1 circulating recombinant form CRF31_BC in Brazil. AB - CRF31_BC is an HIVs-1 recombinant form very prevalent in the southernmost capital city of Brazil, Porto Alegre. Recent studies have been describing a growing number of cases of infection by CRF31_BC in other Brazilian cities and countries, suggesting a process of expansion of this strain. Aiming to describe the city of origin, dispersion routes and demographic history of CRF31_BC, this study analyzed all HIV-1 CRF31_BC and Brazilian BC mosaic publicly available sequences. CRF31_BC classification was performed by bootscanning and tree reconstruction methods. Bayesian phylogeographic and phylodynamic model approaches were used to reconstruct the spatiotemporal and demographic history of 95 sequences identified as CRF31_BC-like. Porto Alegre was estimated to be the origin and center of the dispersion of the CRF31_BC for most of the analyzed locations. However, some viral transitions independent from Porto Alegre were observed in other cities from the Rio Grande do Sul state and also in other Brazilian states. The estimated CRF31_BC epidemic growth rate was similar to subtype C and B in Brazil. Our findings suggest that CRF31_BC, although mostly prevalent in south region, is circulating nation-wide with some localities presenting autochthonous transmissions. PMID- 29601873 TI - Homocysteine up-regulates ETB receptors via suppression of autophagy in vascular smooth muscle cells. AB - The change of autophagy is implicated in cardiovascular diseases (CVDs). Homocysteine (Hcy) up-regulates endothelin type B (ETB) receptors in vascular smooth muscle cells (VSMCs). However, it is unclear whether autophagy is involved in Hcy-induced-up-regulation of ETB receptors in VSMCs. The present study was designed to examine the hypothesis that Hcy up-regulates ETB receptors by inhibiting autophagy in VSMCs. Hcy treated the rat superior mesenteric artery (SMA) without endothelium in the presence and absence of AICAR, rapamycin or MHY1485 for 24 h. The contractile responses to sarafotoxin 6c (S6c) (an ETB receptor agonist) were studied using a sensitive myograph. Levels of protein expression were determined using Western blot analysis. Punctate staining of LC3B was exanimated by immunofluorescence using confocal microscopy. The results showed that Hcy inhibited AMPK, and activated mTOR, followed by impairing autophagy, and increased the levels of ETB receptor protein expression and the ETB receptor-mediated contractile responses to S6c in SMA without endothelium. However, these effects were reversed by AICAR or rapamycin. Additionally, MHY1485 up-regulated the AICAR-inhibited ETB receptor-mediated contractile response and the levels of ETB receptor protein expression in presence of Hcy. In conclusion, this suggested that Hcy up-regulated ETB receptors by inhibiting autophagy in VSMCs via AMPK/mTOR signaling pathway. PMID- 29601874 TI - Isolating the influences of fluid dynamics on selectin-mediated particle rolling at venular junctional regions. AB - The objective of this study was to isolate the impact of hydrodynamics on selectin-mediated cell rolling in branched microvessels. Significant advancements have been made in furthering the understanding of complex interactions between biochemical and physical factors in the inflammatory cascade in simplified planar geometries. However, few studies have sought to quantify the effects of branched configurations and to isolate the effects of associated fluid forces. Experimental techniques were developed to perform in vitro adhesion experiments in Y-shaped micro-slides. The micro-slides were coated with P-selectin and microspheres coated with Sialyl-Lewisx were observed as they rolled in the chambers at different wall shear stresses. Study results revealed that microsphere rolling velocities and rolling flux were lowest in regions closest to the apex of a junctional region and were dependent on both branch angle and wall shear stress. The regions closest to the junctional region were shown to have low bulk flow velocities and shear stresses using computational fluid dynamics (CFD) modeling. Collectively, the study demonstrates that despite the presence of a uniform coating of P-selectin, hydrodynamic factors associated with the chamber geometry yield non-uniform effects on particle behavior. These findings could explain why cells have been observed to preferentially adhere or transmigrate near junctional regions. Future characterization of inflammatory processes in microvascular network configurations is therefore crucial for furthering our fundamental understanding of inflammation. PMID- 29601875 TI - Microvascular abnormalities in dry eye patients. AB - This study was conducted to evaluate conjunctival blood flow velocities and microvascular network density in patients with dry eye disease (DED). Twenty-five patients with DED and 25 healthy controls were recruited. The microvasculature and microcirculation of the temporal bulbar conjunctiva of the right eyes were assessed using a functional slit-lamp biomicroscope. Vascular variables included blood flow velocity (BFV), blood flow rate (BFR), microvascular network density and vessel diameter. A fractal analysis was performed using the box counting method to measure the fractal dimension (Dbox) representing the vessel density. The bulbar BFV was 0.59 +/- 0.09 mm/s in the DED group and 0.47 +/- 0.12 in the control group (P < 0.001). BFR was 169.5 +/- 1.8 in the DED group compared to the control group (107.2 +/- 49.6) (P < 0.001). Dbox was higher in DED patients (1.65 +/- 0.04) than controls (1.60 +/- 0.07, P < 0.05). Moreover, the vessel diameter was larger in the DED group (21.8 +/- 1.8 MUm) compared with controls (17.9 +/- 2.2 MUm, P < 0.001). Dbox was positively related with ocular surface disease index (OSDI) in patients with DED (r = 0.54, P = 0.008). Microvascular alterations were found in the bulbar conjunctiva of DED patients, including increased blood flow velocity, higher vessel density and larger vessel diameter. PMID- 29601876 TI - Isolation, purification and characterization of exopolysaccharide produced by Leuconostoc pseudomesenteroides YF32 from soybean paste. AB - A water-soluble exopolysaccharide (EPS)-producing strain YF32 was isolated from soybean paste, which was then identified as Leuconostoc pseudomesenteroides. After culturing the strain in Man-Rogosa-Sharpe (MRS) medium containing 5% sucrose at 30 degrees C for 48h, the EPS was purified, and a yield of 12.5g/L was achieved. The weight-average molecular weight (Mw) was 5.54*106Da by high performance size-exclusion chromatography (HPSEC). The structural characterization of the purified EPS was determined by gas chromatography (GC), Fourier transform infrared (FT-IR), 1H, 13C nuclear magnetic resonance (NMR) spectroscopy. The results demonstrated that the exopolysaccharide was glucan with a peak, a linear backbone composed of consecutive alpha-(1->6)-linked d glucopyranose units. No branching was observed in the dextran structure. The degradation temperature (Td) of EPS was 307.62 degrees C, which suggested that dextran exhibited high thermal stability. YF32 dextran also showed high water solubility and emulsibility. All results suggested that dextran has the potential to be applied in food fields as a food additive. PMID- 29601877 TI - A design optimization study on synthesized nanocrystalline cellulose, evaluation and surface modification as a potential biomaterial for prospective biomedical applications. AB - In the present study, nanocrystalline cellulose (NCC) was prepared via acid hydrolysis and synthesis parameters were optimized via response surface modelling with a determined maximum NCC yield of 43.8%. The optimized NCC sample was subsequently surface modified via epichlorohydrin-mediated amination forming aminated nanocrystalline cellulose (A-NCC) with an amine content calculated as 1500MUmol/g. The average particle size and zeta potential were determined 100nm and 325nm for NCC and A-NCC, respectively. Structural properties were analyzed by FTIR, TEM and XRD techniques. The obtained A-NCC as final product depicted a pKa value of 10.86+/-0.07 demonstrating favourable protonation of amine groups at physiological pH allowing the material to be suitable for prospective application in drug delivery and tissue engineering. PMID- 29601878 TI - Phenoloxidase activation, antimicrobial, and antibiofilm properties of beta glucan binding protein from Scylla serrata crab hemolymph. AB - In this study, we purified beta-GBP from hemolymph of Scylla serrata crabs using affinity chromatography. The purified S. serrata beta-GBP (Ss-beta-GBP) had 100kDa molecular mass in the SDS-PAGE. MALDI-TOF/TOF analysis was conducted, revealing that the purified 100kDa protein had 96% similarity with beta-GBP of Astacus leptodactylus. Ss-beta-GBP was characterized using high-performance liquid chromatography (HPLC), X-ray diffraction (XRD) analysis, circular dichroism (CD) and Fourier transform infrared (FTIR) spectroscopy, which confirmed the structure of the Ss-beta-GBP. The purified Ss-beta-GBP was functionally analyzed by yeast agglutination and phagocytic reaction assays. Moreover, the PO enhancing ability of Ss-beta-GBP was evidenced through PO activity. Specifically, the antibacterial activity of the Ss-beta-GBP against Gram-positive (Enterococcus faecalis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria was evaluated by determining its minimum inhibitory concentration (MIC)<60MUg/ml for all tested species. Furthermore, the antibiofilm efficacy of Ss-beta-GBP at 50 and 100MUg/ml was outlined using light microscopy and confocal laser scanning microscopy (CLSM). Bacterial viability assays also outlined the dose-dependent activity of Ss-beta-GBP based on the ratio of live/dead bacterial cells. The results of this study revealed that crab-borne Ss-beta-GBP might be widely used to suppress the growth of pathogenic bacteria. PMID- 29601879 TI - Thermal restraint of a bacterial exopolysaccharide of shallow vent origin. AB - To dynamically characterize the thermal properties of the fructose-rich exopolysaccharide (EPS1-T14), produced by the marine thermophilic Bacillus licheniformis T14, the Attenuated Total Reflectance Fourier Transform Infra-Red spectroscopy was coupled to variable temperature ranging from ambient to 80 degrees C. The spectra were analyzed by the following innovative mathematical tools: i) non-ideal spectral deviation, ii) OH-stretching band frequency center shift, iii) spectral distance, and iv) wavelet cross-correlation analysis. The thermal restraint analysis revealed that the whole EPS1-T14 system possessed high stability until 80 degrees C, and suggested that fucose was mainly involved in the EPS1-T14 thermal stability, whereas glucose was responsible for its molecular flexibility. Our results provide novel insights into the thermal stability properties of the whole EPS1-T14 and into the role of its main monosaccharidic units. As a new biopolymer, the thermostable EPS1-T14 could be used in traditional biotechnology fields and in new biomedical areas, as nanocarriers, requiring high temperature processes. PMID- 29601880 TI - Dual responsive aerogel made from thermo/pH sensitive graft copolymer alginate-g P(NIPAM-co-NHMAM) for drug controlled release. AB - Alginate was grafted with NIPAM and NHMAM successfully, and a new responsive copolymer, alginate-g-P(NIPAM-co-NHMAM), was obtained. A novel dual responsive polysaccharide-based aerogel with thermo/pH sensitive properties was designed from the copolymer as drug controlled release system. The chemical structure of the copolymer was characterized by FT-IR and 1H NMR. Lower critical solution temperature (LCST) of the copolymer covered a wide temperature range from 27.6 degrees C to 42.2 degrees C, which could be adjusted with changing the ratio between NIPAM and NHMAM. The dual responsive aerogel had a three-dimensional network structure. As a drug controlled release system, the aerogel was high responsive to both temperature and pH with drug loading efficiency up to 13.24%. Above LCST, the aerogel had a faster drug release, and drug was completely released in neutral environment, while the drug release was obstructed in acid environment. Furthermore, the drug release mechanism of the aerogel was illuminated. These results indicated that the dual responsive aerogel was a promising candidate for drug carriers. PMID- 29601881 TI - Effect of different types and concentrations of emulsifier on the characteristics of kappa-carrageenan films. AB - kappa-Carrageenan films derived from Euchema cottoni containing different types and concentrations of emulsifier were developed. Film formation without the addition of emulsifier was used as a control. The physical, mechanical, optical and microstructural properties of these films were determined. Different types of emulsifiers (Tween 20, Tween 40 and Tween 80) exerted significant effects (P<=0.05) on the thickness, moisture content and opacity of the films. Additionally, Tween 20 and Tween 40 with concentrations from 0.1 to 0.5% (v/v) significantly (P<=0.05) improved the tensile strength of the films, ranging from 7.35 to 13.83MPa. The water vapor permeability of the carrageenan films was significantly (P<=0.05) affected by both factors. Increasing the emulsifier concentration also caused an increment in the number of lipid droplets contributing to a smooth surface. Therefore, this study suggests that different types and concentrations of emulsifiers play essential roles in determining the physical properties of carrageenan films. PMID- 29601882 TI - A novel serine protease from strawberry (Fragaria ananassa): Purification and biochemical characterization. AB - In this study, a protease enzyme was purified from strawberry by using Sepharose 4B-l-tyrosine-p-amino benzoic acid affinity chromatography. The molecular weight of pure protease was determined 65.8 kDa by SDS-PAGE. The single band observed on the gel showed that the enzyme had a single polypeptide chain and was successfully purified. Purification of the protease by the chromatographic method resulted in a 395.6-fold increase in specific activity (3600 U/mg). Optimum pH and temperature for the enzyme were 6 and 40 degrees C, respectively. The protease was stable at a wide temperature range of 40 to 70 degrees C and a pH range of 3.0 to 9.0. Co2+ ions stimulated protease activity very strongly. Cu2+, Hg2+, Cd2+ and Mn2+ ions significantly inhibited protease activity. While 2 propanol completely inhibited the enzyme, the enzyme maintained its activity better in the presence of ethanol and methanol. The strawberry protease showed the highest specificity towards hemoglobin among all the natural substrates tested. The specificity of the enzyme towards synthetic substrates was also investigated and it was concluded that it has broad substrate specificity. The obtained results indicated that this purified protease was highly-likely a serine protease and its activity was significantly affected by the presence of metal ions. PMID- 29601883 TI - Synthesis and antidiabetic activity of selenium nanoparticles in the presence of polysaccharides from Catathelasma ventricosum. AB - Selenium nanoparticles (SeNPs) were prepared by adding Catathelasma ventricosum polysaccharides (CVPs) to the redox system of selenite and ascorbic acid. Taking particle size as an investigation index, the optimal synthesis conditions of CVPs SeNPs were obtained by orthogonal test. Herein, the diameter, morphology, and stability of the CVPs-SeNPs were characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM). Moreover, the antidiabetic activities of CVPs-SeNPs were evaluated by STZ (streptozocin)-induced diabetic mice. The obtained results showed that, optimum synthesis conditions of CVPs-SeNPs were: ultrasonic time 60min, concentration of Vc 0.04M, reaction time 2h, pH7.0. Under these conditions, mean diameter of the synthesized CVPs-SeNPs was around 49.73nm. TEM of CVPs-SeNPs prepared in optimal conditions showed individual and spherical nanostructure. CVPs-SeNPs (particle size of about 50nm) could be stable for approximately 3months at 4 degrees C, but only 1month at 25 degrees C. The results on serum profiles and antioxidant enzymes levels revealed that CVPs-SeNPs had a potential antidiabetic effect. In addition, CVPs-SeNPs showed significantly higher antidiabetic activity (p<0.05) than other selenium preparations such as SeNPs, selenocysteine, sodium selenite. PMID- 29601884 TI - Fabrication of regenerated wool keratin/polycaprolactone nanofiber membranes for cell culture. AB - Regenerated wool keratin is a promising natural material for tissue engineering. In the present study, l-cysteine redox method was performed to extract keratin from wool. Then the different ratios of keratins blended with polycaprolactone (PCL) in formic acid were electrospun to produce nanofibrous membrane. The morphology, biodegradation degree in phosphate buffer saline (PBS) and cell culture were closely investigated. It is found that adding keratin to the PCL nanofiber can improve the hydrophilicity of the as-spun nanofiber mats and then promote the cell adhesion and proliferation of the composite nanofibrous mats. The nanofiber membrane with the highest hydrophilicity had the highest cellular compatibility. PMID- 29601885 TI - An image registration protocol to integrate electrophysiology, MRI and neuropathology data in epileptic patients explored with intracerebral electrodes. AB - BACKGROUND: Several attempts have been made to coregister in vivo MRI with the histopathology of surgical samples, aiming to validate new MRI biomarkers and improve the detection of epileptogenic lesions. As a further implementation, we propose a method to reconstruct the anatomical localization of the intracerebral electrodes on the histological sections, developing a coregistration protocol to match the in vivo MRI onto the ex vivo MRI obtained from the surgical specimen. NEW METHOD: Since the ex vivo MRI is natively in geometrical correspondence with histology slices, the goal of the coregistration process is to compute the transform function mapping the clinical MRI space to the ex vivo MRI. Electrodes and leads, identified in CT-MRI, can then be segmented and translated onto the histological slices. RESULTS: Step-by-step, qualitative visual inspection showed an improved matching of the anatomical structures or boundaries and electrodes positions between the two modalities. The quantitative evaluation of the coregistration protocol reported a mean error ranging between 0.82 and 1.27 mm when a sufficient number of landmarks, particularly in the core of the specimen, were clearly identified. COMPARISON WITH EXISTING METHODS: Because histology was performed according to ex vivo MRI geometry we chose to transform the in vivo onto the ex vivo MRI, differently from other methods. CONCLUSIONS: Interesting applications of the method will include correlating the locally-generated pathological electrical activity with the subtle morphological alterations of the tissue, and histologically validating the origin of signal alterations or quantitative parameter variations in MRI studies. PMID- 29601887 TI - Schizotypal traits and forearm motor control against self-other produced action in a bimanual unloading task. AB - The present study investigated the relation between schizotypy and motor control against self- or other-produced action. We used an unloading task to focus on the timing component of anticipatory motor control. In the task, a weight was removed from a participants' hand by the participants themselves or by an experimenter (voluntary versus imposed unloading). Postural disturbance at the removal timing was measured as an index of predictive function in motor control. We hypothesized that the postural disturbance in the voluntary unloading would be positively related to schizotypal traits; however, the results did not support this theory. The results showed almost zero correlation between the schizotypy scores and the postural disturbance in the voluntary unloading condition. In contrast, the schizotypy scores positively correlated with the postural disturbance in the imposed unloading condition. These findings were replicated across two participant groups and two schizotypy scales. Further analyses on subscales of the schizotypy questionnaire found moderate levels of positive correlation between each subscale for Cognitive-Perceptual and Disorganization factors and the disturbance. Accordingly, the present study did not support the idea that non pathological individuals with high schizotypal traits have deficits in prediction of self-produced actions, at least for a temporal domain. Instead, the results suggested that individuals with high schizotypal traits, particularly for the positive and disorganization symptoms, are not good at responding to others produced actions. The schizophrenic symptoms were discussed in terms of the failure in the processes executed after calculating prediction of sensory consequences and dysfunction in internal models for "other people". PMID- 29601886 TI - A method to assess randomness of functional connectivity matrices. AB - BACKGROUND: Functional magnetic resonance imaging (fMRI) allows for the measurement of functional connectivity of the brain. In this context, graph theory has revealed distinctive non-random connectivity patterns. However, the application of graph theory to fMRI often utilizes non-linear transformations (absolute value) to extract edge representations. NEW METHOD: In contrast, this work proposes a mathematical framework for the analysis of randomness directly from functional connectivity assessments. The framework applies random matrix theory to the analysis of functional connectivity matrices (FCMs). The developed randomness measure includes its probability density function and statistical testing method. RESULTS: The utilized data comes from a previous study including 603 healthy individuals. Results demonstrate the application of the proposed method, confirming that whole brain FCMs are not random matrices. On the other hand, several FCM submatrices did not significantly test out of randomness. COMPARISON WITH EXISTING METHODS: The proposed method does not replace graph theory measures; instead, it assesses a different aspect of functional connectivity. Features not included in graph theory are small numbers of nodes, testing submatrices of an FCM and handling negative as well as positive edge values. CONCLUSION: The random test not only determines randomness, but also serves as an indicator of smaller non-random patterns within a non-random FCM. Outcomes suggest that a lower order model may be sufficient as a broad description of the data, but it also indicates a loss of information. The developed randomness measure assesses a different aspect of randomness from that of graph theory. PMID- 29601888 TI - Reward sensitivity following boredom and cognitive effort: A high-powered neurophysiological investigation. AB - What do people feel like doing after they have exerted cognitive effort or are bored? Here, we empirically test whether people are drawn to rewards (at the neural level) following cognitive effort and boredom. This elucidates the experiences and consequences of engaging in cognitive effort, and compares it to the consequences of experiencing boredom, an affective state with predicted similar motivational consequences. Event-related potentials were recorded after participants (N = 243) were randomized into one of three conditions - boredom (passively observing strings of numbers), cognitive effort (adding 3 to each digit of a four-digit number), or control. In the subsequent task, we focused on the feedback negativity (FN) to assess the brain's immediate response to the presence or absence of reward. Phenomenologically, participants in the boredom condition reported more fatigue than those in the cognitive effort condition, despite reporting exerting less effort. Results suggest participants in the boredom condition exhibited larger FN amplitude than participants in the control condition, while the cognitive effort condition was neither different from boredom nor control. The neural and methodological implications for ego depletion research, including issues of replicability, are discussed. PMID- 29601889 TI - Sleep deprivation increases the costs of attentional effort: Performance, preference and pupil size. AB - Sleep deprivation (SD) consistently degrades performance in tasks requiring sustained attention, resulting in slower and more variable response times that worsen with time-on-task. Loss of motivation to exert effort may exacerbate performance degradation during SD. To test this, we evaluated sustained performance on a vigilance task, combining this with an effort-based decision making task and pupillometry. Vigilance was tested at rest and after sleep deprivation, under different incentive conditions (1, 5 or 15 cents for fast responses). Subsequently, preference measures were collected from an effort discounting task, in which a commensurate reward was offered for maintaining attentional performance for different durations (1, 5, 10, 20 or 30 min). Vigilance was impaired during SD, in a manner modulated by reward value. Preference metrics showed that the value of available rewards was discounted by task duration, an effect compounded by SD. Pupillometry revealed that arousal was modulated during SD in a value-based manner, and moment-to-moment fluctuations in pupil diameter were directly predictive of performance. Together, these data demonstrate that attentional performance can be interpreted within a value-based effort allocation framework, such that the perceived cost of attentional effort increases after sleep deprivation. PMID- 29601890 TI - The silencing of replication protein A1 induced cell apoptosis via regulating Caspase 3. AB - AIMS: Gastrointestinal cancers are a kind of deadly malignancy afflicting close to a million peoples worldwide. 5-Fluorouracil (5-Fu) is a main chemotherapeutic agent for cancer treatment. However, prolonged exposure of 5-Fu to cancer cells may cause chemoresistance and decrease the therapeutic potential of 5-Fu. MAIN METHODS: Replication protein A (RPA) is a component of the origin recognition complex. In our study, we explored the role of RPA1 in hepatocellular carcinoma cell SMMC-7721, gastric cancer cell SGC-7901 and colorectal cancer HT-29 via lentiviral particles infection. Flow cytometry assay was used to examine the effect of RPA1 on cell proliferation, cell cycle and apoptosis. Western blot was employed to determine the role of RPA1 on Caspase 3 expression. KEY FINDINGS: Immunohistochemstry results showed that RPA1 was highly expressed in colorectal cancer tissues. Only 5-Fu or the knockdown of RPA1 suppressed cell clone formation, induced cell cycle arrest at the G1 phase and promoted cell apoptosis by regulating the protein level of Caspase 3. And the combination of the application of 5-Fu and RPA1 silencing significantly enhanced the above effects. SIGNIFICANCE: RPA1 serves as an oncogene during gastrointestinal cancers progression. These studies reveal a new target for gastrointestinal cancers therapy, and the combination of 5-Fu and silencing of RPA1 provides a new attractive therapeutic measure for gastrointestinal cancers.

AB - AIMS: Dehydroepiandrosterone (DHEA) is an adrenal steroid hormone that is a precursor of sexual hormones. It is reduced during aging and is strongly associated with insulin resistance and obesity. There is evidence for beneficial effects of this steroid, in both human and animal models, during perimenopause. However, the impact of DHEA treatment during late postmenopause on glucose metabolism is not clearly documented. We tested the hypothesis that DHEA supplementation could improve insulin sensitivity in an ovariectomized obese rat model (OVX) that was fed a high-fat diet for 11 weeks. MAIN METHODS: Female Wistar rats at 8 weeks of age were OVX or SHAM-operated. Eight weeks after the surgery, the animals were randomly treated with vehicle or DHEA for 3 weeks. Food intake, metabolic parameters and insulin sensitivity were evaluated. KEY FINDINGS: Following the ovariectomy, increased body weight gain, adiposity index, and feeding efficiency were observed, despite there being no change in food and energy intake. The OVX rats also displayed glucose intolerance, insulin resistance, decreased insulin-induced IRS1/2 tyrosine phosphorylation in the skeletal muscle, and reduced serum VLDL-c and TAG levels. OVX rats treated with 10 mg/kg DHEA (OVX + DHEA) exhibited estradiol (E2) serum levels similar to SHAM animals, with no change in uterus mass. DHEA treatment also resulted in an increase in energy intake. SIGNIFICANCE: Despite the positive effects of DHEA supplementation observed in menopausal women and ovariectomized rats, a potential negative effect on glucose metabolism and insulin action in the late postmenopausal condition in diet-induced obese OVX rats are reported.

AB - Neuraminidase inhibitors (NAIs) are the main class of antivirals currently used for the treatment of influenza infections. As influenza viruses are constantly evolving, drug-resistance can emerge resulting in reduced effectiveness of treatment. This study evaluated the presence of molecular markers associated with NAI susceptibility in 724 influenza A(H1N1)pdm09 positive samples from Brazilian surveillance system from the 2014-2016 seasons, including 76 isolates tested for oseltamivir (OST) susceptibility and 23 isolates also tested for zanamivir, peramivir and laninamivir susceptibility. We identified the H275Y (n = 3) and I223K (n = 1) NA substitutions, associated with reduced inhibition (RI) by the NAIs. Noteworthy, no epidemiological links were identified among the patients infected with the mutant viruses. Phylogenetic analysis from NA and hemagglutinin genes showed that mutant viruses were not clustered. All mutant virus strains carried the permissive substitutions V241I and N369K, in addition to the N386K, which has been shown to destabilize the NA structure. Functional NA analysis of one virus containing the H275Y mutation confirmed its highly RI profile to OST and peramivir and demonstrated that it had decreased viral replication and NA thermostability compared to the wild type virus. The remaining tested isolates presented normal inhibition profile to the NAIs tested. In conclusion, the overall frequency of influenza A(H1N1)pdm09 viruses bearing mutations associated with NAI RI was 0.6%, similar to what has been observed in recent global studies. PMID- 29601893 TI - Ribavirin-related compounds exert in vitro inhibitory effects toward rabies virus. AB - Rabies remains an invariably fatal neurological disease despite the availability of a preventive vaccination and post-exposure prophylaxis that must be immediately administered to the exposed individual before symptom onset. There is no effective medication for treatment during the symptomatic phase. Ribavirin, a guanine nucleoside analog, is a potent inhibitor of rabies virus (RABV) replication in vitro but lacks clinical efficacy. Therefore, we attempted to identify potential ribavirin analogs with comparable or superior anti-RABV activity. Antiviral activity and cytotoxicity of the compounds were initially examined in human neuroblastoma cells. Among the tested compounds, two exhibited a 5- to 27-fold higher anti-RABV activity than ribavirin. Examination of the anti RABV mechanisms of action of the compounds using time-of-addition and minigenome assays revealed that they inhibited viral genome replication and transcription. Addition of exogenous guanosine to RABV-infected cells diminished the antiviral activity of the compounds, suggesting that they are involved in guanosine triphosphate (GTP) pool depletion by inhibiting inosine monophosphate dehydrogenase (IMPDH). Taken together, our findings underline the potency of nucleoside analogs as a class of antiviral compounds for the development of novel agents against RABV. PMID- 29601894 TI - Susceptibility of paramyxoviruses and filoviruses to inhibition by 2'-monofluoro- and 2'-difluoro-4'-azidocytidine analogs. AB - Ebolaviruses, marburgviruses, and henipaviruses are zoonotic pathogens belonging to the Filoviridae and Paramyxoviridae families. They exemplify viruses that continue to spill over into the human population, causing outbreaks characterized by high mortality and significant clinical sequelae in survivors of infection. There are currently no approved small molecule therapeutics for use in humans against these viruses. In this study, we evaluated the antiviral activity of the nucleoside analog 4'-azidocytidine (4'N3-C, R1479) and its 2'-monofluoro- and 2' difluoro-modified analogs (2'F-4'N3-C and 2'diF-4'N3-C) against representative paramyxoviruses (Nipah virus, Hendra virus, measles virus, and human parainfluenza virus 3) and filoviruses (Ebola virus, Sudan virus, and Ravn virus). We observed enhanced antiviral activity against paramyxoviruses with both 2'diF-4'N3-C and 2'F-4'N3-C compared to R1479. On the other hand, while R1479 and 2'diF-4'N3-C inhibited filoviruses similarly to paramyxoviruses, we observed 10 fold lower filovirus inhibition by 2'F-4'N3-C. To our knowledge, this is the first study to compare the susceptibility of paramyxoviruses and filoviruses to R1479 and its 2'-fluoro-modified analogs. The activity of these compounds against negative-strand RNA viruses endorses the development of 4'-modified nucleoside analogs as broad-spectrum therapeutics against zoonotic viruses of public health importance. PMID- 29601896 TI - Differentiating between bipolar and unipolar depression in functional and structural MRI studies. AB - Distinguishing depression in bipolar disorder (BD) from unipolar depression (UD) solely based on clinical clues is difficult, which has led to the exploration of promising neural markers in neuroimaging measures for discriminating between BD depression and UD. In this article, we review structural and functional magnetic resonance imaging (MRI) studies that directly compare UD and BD depression based on neuroimaging modalities including functional MRI studies on regional brain activation or functional connectivity, structural MRI on gray or white matter morphology, and pattern classification analyses using a machine learning approach. Numerous studies have reported distinct functional and structural alterations in emotion- or reward-processing neural circuits between BD depression and UD. Different activation patterns in neural networks including the amygdala, anterior cingulate cortex (ACC), prefrontal cortex (PFC), and striatum during emotion-, reward-, or cognition-related tasks have been reported between BD and UD. A stronger functional connectivity pattern in BD was pronounced in default mode and in frontoparietal networks and brain regions including the PFC, ACC, parietal and temporal regions, and thalamus compared to UD. Gray matter volume differences in the ACC, hippocampus, amygdala, and dorsolateral prefrontal cortex (DLPFC) have been reported between BD and UD, along with a thinner DLPFC in BD compared to UD. BD showed reduced integrity in the anterior part of the corpus callosum and posterior cingulum compared to UD. Several studies performed pattern classification analysis using structural and functional MRI data to distinguish between UD and BD depression using a supervised machine learning approach, which yielded a moderate level of accuracy in classification. PMID- 29601895 TI - Chronic administration of amphetamines disturbs development of neural progenitor cells in young adult nonhuman primates. AB - The detrimental effects of amphetamines on developmental stages of NPCs are limited to rodent brain and it is not known if these effects occur in nonhuman primates which are the focus of the current investigation. Young adult rhesus macaques either experienced MDMA only, a combination of amphetamines (MDMA, MDA and methamphetamine) or no amphetamines (controls) and hippocampal tissue was processed for immunohistochemical analysis.Quantitative stereological analysis showed that intermittent exposure to MDMA or the three amphetamines over 9.6 months causes >80% decrease in the number of Ki-67 cells (actively dividing NPCs) and >50% decrease in the number of NeuroD1 cells (NPCs that have attained a neuronal phenotype). Co-labeling analysis revealed distinct, actively dividing hippocampal NPCs in the subgranular zone of the dentate gyrus that were in transition from stem-like radial glia-like cells (type-1) to immature transiently amplifying neuroblasts (type-2a, type-2b, and type-3).MDMA-alone and the combination reduced the number of dividing type-1 and type-3 NPCs and cells that were not NPCs. These data indicate that amphetamines interfere with the division and migration of NPCs. Notably, the reduction in the number of NPCs and immature neurons were not associated with changes in cell death (via apoptosis) or granule cell neuron numbers, indicating that amphetamines selectively affected the generation and maturation of newly born granule cell neurons. In sum, our findings suggest that alterations in the cellular composition in the dentate gyrus during chronic exposure to amphetamines can effect neuroplasticity in the hippocampus and influence functional properties of hippocampal neurons. PMID- 29601897 TI - Does Pain Affect Preference? The Effect of Tonic Laboratory Pain on Discounting of Delayed Rewards. AB - : Chronic pain patients show elevated risk behavior on decision-making tasks, as well as increased health risk behaviors (eg, smoking, prescription opioid abuse). Determining pain's effect on underlying cognitive processes that are associated with risk behavior is confounded by comorbidities linked with chronic pain, including depression, anxiety, and substance abuse. Therefore, to understand pain's effect on delay discounting, a behavioral process assessing the extent to which outcomes are devalued as a function of their delay, the present study evaluated the effect of laboratory pain on delay discounting in healthy young adults (N = 85). Using a mixed factorial design, pain (topical capsaicin and warmth) as well as active control (warmth) groups completed a delay discounting task before and during exposure to their respective manipulations. Whereas the pain condition had no effect on delay discounting, participants' pain intensity, unpleasantness, and pain-induced negative valence were associated with less discounting of delayed rewards. However, the effects were very small. PERSPECTIVE: The results suggest that experimental pain may not increase delay discounting, rather sensitivity to pain predicts a very small decrease in discounting of delayed rewards. Although the results are limited to healthy volunteers, this experimental approach allows us to examine the relationship between pain and delay discounting in a controlled manner. Better understanding of pain-related decision-making may lead to improved treatment of health risk behaviors for individuals experiencing pain. PMID- 29601898 TI - Qualitative and Quantitative Aspects of Pain in Patients With Myotonic Dystrophy Type 2. AB - : Pain is a common but often ignored symptom in patients with myotonic dystrophy type 2 (DM2). In this explorative study, we assessed qualitative and quantitative aspects of pain in DM2 using 4 questionnaires and quantitative sensory testing. A disease control group (fibromyalgia [FMS]) as well as healthy controls were used to compare the results, because pain in DM2 shows many clinical similarities to pain in FMS. Thirty-four patients with genetically confirmed DM2 (71% female, mean age 54 years), 28 patients with FMS, and 33 healthy controls were included, age- as well as sex-matched. Pain prevalence was 65% in DM2, 100% in FMS (P < .001), and 15% in healthy controls (P < .001). The mean of the pressure pain thresholds was lower in DM2 than in healthy controls (P = .016), with the largest differences in the rectus femoris, trapezius, and thenar muscles. Mechanical and electric pain thresholds were significantly higher in DM2 than in FMS, and no differences were found in electric pain thresholds between DM2 and healthy controls. These results confirm that pain is a frequent and important symptom in patients with DM2, affecting quality of life. Peripheral mechanisms of pain seem to play a role in DM2. The widespreadness of the hyperalgesia suggests central sensitization, but this finding was not supported by the other results. This study opens new avenues for further research and eventually novel treatment strategies, in DM2 as well as in other muscular disorders. PERSPECTIVE: This article presents qualitative as well as quantitative aspects of pain in patients with DM2. Pain is a frequent and important symptom in patients with DM2, affecting quality of life. We found mechanical hyperalgesia, indicative of a peripheral mechanism of pain. The widespreadness of hyperalgesia may suggest central sensitization, but this finding was not supported by other results and needs further exploration. PMID- 29601899 TI - Longitudinal changes in bone parameters in young girls with anorexia nervosa. AB - BACKGROUND: Anorexia nervosa (AN) during childhood and adolescence has been reported to adversely affect bone health, but few studies have investigated longitudinal changes. METHOD: DXA-derived bone parameters and body composition were retrospectively assessed in 111 young girls with AN with a median age of 15.4 years (10.9, 19.8). In 68 (61%) vertebral fracture assessment (VFA) was performed and in 31 (28%), a follow-up DXA was performed. Correlations with growth, changes in body composition and effects of illness duration and menstruation were examined. Size adjusted DXA standard deviation scores were calculated for total body (TB) less head bone mineral content (TBLH-BMC) and lumbar spine bone mineral apparent density (LS-BMAD). RESULTS: Mean (range) bone area (BA) for height centile was 27.1 (0-97), and mean lean mass for height centile was 28.8 (0-95) at baseline. Mean (range) LS BMAD was -1.0 (-2.6, 0.8) SDS at first and - 1.2 (-3.0, -0.2) at second DXA (p = 0.023). On follow up, lean mass for height increased from 27th centile (0, 75) to 40th centile (0, 70) (p = 0.006), and fat mass for height increased from 55 g/cm to 67 g/cm (11.3, 124.2) (p < 0.001). Duration of illness was the only negative predictor of LS BMAD (p < 0.0001). Change in height SDS was the only positive predictor of change in TBLH BMC (r = 0.384, p = 0.037), and change in LS BMAD (r-0.934, p < 0.0001). Of 68 patients who had VFA, 4 (5.9%) had a mild vertebral fracture. CONCLUSION: Bones are smaller and less dense in childhood/adolescent AN compared to healthy adolescents. Although there are significant gains in lean mass and fat mass, over time, BMAD SDS decreases slightly. Improvement in BMAD SDS is related to improvement in height SDS. PMID- 29601900 TI - Neonatal hyperinsulinemic hypoglycemia in a patient with 9p deletion syndrome. AB - We report the clinical and neuroradiological findings in a young boy harboring the 9p deletion syndrome including the novel findings of thalamic infarction and germinal matrix haemorrhage and neonatal hyperinsulinemic hypoglycemia. Both the hypoglycemic events and the ventriculomegaly found in this patient have previously only been reported in two patients, while the thalamic infarction and germinal matrix haemorrhage are novel features. PMID- 29601902 TI - Rethinking What We Know About Hemorrhoids. AB - Although hemorrhoids are responsible for considerable economic cost and personal suffering, they have received surprisingly little research attention. In the United States, hemorrhoids are the third most common outpatient gastrointestinal diagnosis with nearly 4 million office and emergency department visits annually. The etiology of hemorrhoids is speculative. A low-fiber diet and constipation have historically been thought to increase the risk for hemorrhoids, but not proven. Symptoms commonly attributed to hemorrhoids include bleeding, pain, pruritus, fecal seepage, prolapse, and mucus discharge. Research has found that these symptoms were equally reported by patients with and without hemorrhoids. Medical therapies for hemorrhoids have not been formally studied except for fiber where the results have been inconsistent. A number of office-based interventions such as rubber band ligation and infrared coagulation are widely used and economically favorable for practitioners. Surgical procedures are effective at eliminating hemorrhoids but may be painful. Given the burden of disease and numerous gaps in our understanding, the time has come for targeted research to understand the cause, symptoms, and best treatment for patients with symptomatic hemorrhoids. PMID- 29601901 TI - 3D-printing porosity: A new approach to creating elevated porosity materials and structures. AB - : We introduce a new process that enables the ability to 3D-print high porosity materials and structures by combining the newly introduced 3D-Painting process with traditional salt-leaching. The synthesis and resulting properties of three 3D-printable inks comprised of varying volume ratios (25:75, 50:50, 70:30) of CuSO4 salt and polylactide-co-glycolide (PLGA), as well as their as-printed and salt-leached counterparts, are discussed. The resulting materials are comprised entirely of PLGA (F-PLGA), but exhibit porosities proportional to the original CuSO4 content. The three distinct F-PLGA materials exhibit average porosities of 66.6-94.4%, elastic moduli of 112.6-2.7 MPa, and absorbency of 195.7-742.2%. Studies with adult human mesenchymal stem cells (hMSCs) demonstrated that elevated porosity substantially promotes cell adhesion, viability, and proliferation. F-PLGA can also act as carriers for weak, naturally or synthetically-derived hydrogels. Finally, we show that this process can be extended to other materials including graphene, metals, and ceramics. STATEMENT OF SIGNIFICANCE: Porosity plays an essential role in the performance and function of biomaterials, tissue engineering, and clinical medicine. For the same material chemistry, the level of porosity can dictate if it is cell, tissue, or organ friendly; with low porosity materials being far less favorable than high porosity materials. Despite its importance, it has been difficult to create three dimensionally printed structures that are comprised of materials that have extremely high levels of internal porosity yet are surgically friendly (able to handle and utilize during surgical operations). In this work, we extend a new materials-centric approach to 3D-printing, 3D-Painting, to 3D-printing structures made almost entirely out of water-soluble salt. The structures are then washed in a specific way that not only extracts the salt but causes the structures to increase in size. With the salt removed, the resulting medical polymer structures are almost entirely porous and contain very little solid material, but the maintain their 3D-printed form and are highly compatible with adult human stem cells, are mechanically robust enough to use in surgical manipulations, and can be filled with and act as carriers for biologically active liquids and gels. We can also extend this process to three-dimensionally printing other porous materials, such as graphene, metals, and even ceramics. PMID- 29601903 TI - Endoscopic Drainage of Pancreatic Fluid Collections. AB - Endoscopy has emerged as a mainstay in the management of pancreatic fluid collections (PFCs), representing an important advance in clinical medicine that has significantly improved the risk-benefit ratio of treating this complex patient population. While endoscopic pseudocyst drainage has generally supplanted surgical and percutaneous approaches, the optimal strategy for walled-off necrosis remains variable and multi-disciplinary despite an emerging trend from randomized trials favoring endoscopy. Although several issues pertaining to endoscopic drainage appear to have been settled - such as the use of endoscopic ultrasound - other pressing questions - including the optimal prosthesis and debridement strategy - remain unanswered, and rigorous investigation is needed. This review aims to provide an evidence-based but practical appraisal of the endoscopic drainage of PFCs through the perspective of the author, with an emphasis on relevant clinical and endoscopic considerations and important research questions. PMID- 29601904 TI - Protoporphyrin IX formation after application of methyl aminolevulinate on the face and scalp with and without prior curettage. AB - BACKGROUND: Pulse photodynamic therapy (PDT) is carried out as classical PDT except that methyl aminolaevulinate (MAL) is removed after 30 min. Protoporphyrin IX (PpIX) accumulation becomes lower after 3 h in pulse-PDT than in classical PDT, but pulse-PDT still has full treatment effect on actinic keratosis (AK). The present study aimed to investigate when PpIX formation in classical PDT without curettage reaches the PpIX level in pulse-PDT with curettage in the skin of the face and scalp. METHODS: Fourteen patients with AKs in the face and scalp were included in this pilot study. Each patient had two fields randomly allocated to two different regimes: (i) continuing MAL incubation without prior curettage ( Cur) and (ii) 30 min MAL incubation after curettage (+Cur). The PpIX level in each field was measured with a hand-held fluorescence photometer every 30 min for 6 h after MAL application. No illumination was performed. RESULTS: The median PpIX level in the +Cur field after 3 h was 22 arbitrary units (AU), which represents the amount of PpIX that could have been photobleached after pulse-PDT with maximal treatment effect. After 3 h the median PpIX level in the -Cur field was 20 AU, which was not significantly different from the level in the +Cur field (p = 0.9). CONCLUSIONS: We propose PDT without curettage as follows: 3 h of MAL incubation and subsequently sufficient illumination. The treatment effect of this regime should be tested to verify if curettage of the face and scalp area may be omitted in PDT. PMID- 29601906 TI - Melatonin therapy for diabetic cardiomyopathy: A mechanism involving Syk mitochondrial complex I-SERCA pathway. AB - Melatonin and its metabolites have been demonstrated to modulate the glucose, dyslipidemia and other metabolic disorders. This study aimed to explore a novel mechanism responsible for diabetic cardiomyopathy development, and also validated whether melatonin played a protective role in repairing damaged heart in the diabetes setting. Our data demonstrated that spleen tyrosine kinase (Syk) was activated by chronic high-glucose stimulus and contributed to the development of diabetic cardiomyopathy. However, genetic ablation of Syk or supplementation of melatonin to inhibit Syk activation improved diabetic myocardial function, reduced cardiac fibrosis and preserved cardiomyocytes viability. Mechanistically, activated Syk repressed the expression and activity of mitochondrial complex I (COX-1), unfortunately evoking mitochondrial and/or cellular ROS overproduction. Subsequently, excessive superoxide facilitated SERCA peroxidation which failed to re-uptake the cytoplasmic calcium back into endoplasmic reticulum (ER), leading to cellular calcium overload. Finally, activated oxidative stress and calcium overload collectively promoted the high-glucose-induced cardiomyocytes death via caspase-9-related mitochondrial apoptosis and caspase-12-involved ER apoptosis, respectively. Interestingly, inhibition of Syk via Syk genetic ablation or melatonin administration blocked Syk/COX-1/SERCA signalling pathways, and thus abolished mitochondrial- and ER-mediated cardiomyocyte death in the setting of diabetes. Based on these results, we suggest a novel pathway by which high glucose stimulus induces diabetic cardiomyopathy is possibly through an activation of Syk/COX-1/SERCA axis which could be abrogated by melatonin treatment. PMID- 29601905 TI - Theranostic-PDT with the antibody anti isoform 4 SOD mitocondrial labeled with PpIX in the lung cancer cell line A-549. AB - BACKGROUND: In this work, a drug product composed of an IgM antibody derived from a hybridoma subclone 4C1F6D5G7B8 was prepared and further labeled with PpIX to be used in cell lines A-549 and MRC-5. The aim of this work was to evaluate the potential theranostic activity of the obtained product together with photodynamic therapy (PDT). METHODS: The IgM antibody labeled with PpIX was used in different concentrations to perform theranostics with PDT in cell lines A-549 and MRC-5 in order to identify the specificity of IgM antibody in lung cancer cells by means of a LED-irradiation system set at 630 nm. The location of the conjugate was further determined by confocal microscopy. RESULTS: The theranostic with conjugate Ab-PpIX in the A-549 cell lines showed fluorescence by confocal microscopy, whereas the MRC-5 cell line showed no reactivity. The PDT with the conjugate in the cell line A-549 decreased its viability 70% compared to the control. On the contrary, with the MRC-5 cell line no viability diference was shown. The confocal microscopy applied to the cell line A-549 showed that the Ab PpIX was majorly located at the cytoplasm. CONCLUSION: Ab-PpIX showed therapeutical potential in lung cancer cells A-549 and had no activity in non cancerous lung cells (MCR-5). PMID- 29601907 TI - Inhibition of DNMT suppresses the stemness of colorectal cancer cells through down-regulating Wnt signaling pathway. AB - Cancer stem cell (CSC) theory reveals a new insight into the understanding of tumorigenesis and metastasis. Recently, DNA methylation is suggested to be a potential epigenetic mechanism for maintenance of CSCs. What's more, studies have shown that DNA methyltransferase (DNMT) is essential for CSCs and deletion of DNMT can reduce tumorigenesis by limiting CSC pool. Therefore, targeting the epigenetic modifiers especially DNA methylation offers an optional strategy for treating human cancers. In the present study we found that DNMT inhibitor 5-Aza 2'-deoxycytidine (5-AzaDC) markedly reduced colorectal CSC abundance in vitro and suppressed liver metastatic tumor growth in vivo. And 5-AzaDC inhibited the expression of active beta-catenin and down-regulated the Wnt signaling pathway. The Wnt inhibitors were frequently inactivated by promoter methylation in colorectal cancer; however analysis of TCGA data base showed that only the expression of SFRP1 was significantly reduced in tumors compared to normal tissues. In addition, restoring of SFRP1 expression inhibited the stem cell-like potential of colorectal cancer cells. Our results indicated that inhibition of DNMT blocked the self-renewal of colorectal CSCs and SFRP1 was essential for the maintenance of colorectal CSCs. PMID- 29601908 TI - Outcomes of Patients Undergoing Surgical Management of Multiple Ventricular Septal Defects. AB - Surgical treatment of multiple ventricular septal defects (VSDs) has advanced significantly in recent years, yet remains technically challenging. With high rates of complications and reoperations, we sought to assess the outcomes of patients undergoing a variety of management techniques for multiple VSDs. From 1988 to 2015, 157 consecutive patients underwent surgical management of multiple VSDs at a median age of 2.2 months (2 days-16 years). Sixty-nine patients (44%) had exclusively multiple VSDs, 62 patients (39%) had multiple VSDs with concomitant intracardiac anomalies, and 26 patients (17%) had multiple VSDs with aortic arch anomalies. The predominant techniques used at the initial operations were patch closure (84 patients), pulmonary artery band (83 patients), suture closure (37 patients), and sandwich technique (13 patients). Eighteen patients underwent ventriculotomies. There were 3 hospital deaths (2%). Mean follow-up time was 8.6 +/- 6 years (1 day-22 years). Four patients died during follow-up, whereas freedom from reoperations was 52% (95% confidence interval 42%-61%) at 16 years. Freedom from reoperation was significantly lower in the 1988-2002 era than in the post-2002 era (38% vs 73%, P = 0.016). Pacemaker implantation was ultimately required in 9% (14 of 150) of patients. No deleterious impact of a ventriculotomy could be detected. Surgical treatment of multiple VSDs can be performed with excellent short- and long-term survival, and normal late functional outcome, however, carries a significant rate of reoperation. The recent inclusion of absorbable pulmonary artery bands and the sandwich technique appear safe and are useful adjuncts in these patients.

AB - Vitacoxib, a selective COX-2 inhibitor, is approved for the relief of pain and inflammation associated with orthopedic surgery and osteoarthritis in dogs. In the current study, a chronic toxicity research was performed to evaluate the safety of vitacoxib in male and female rats for long-term. Vitacoxib was dosed orally to groups of rats for 180 days at 1.2, 6, 30 mg/kg bw/day by gavage. The chronic study oral administration of vitacoxib did not show observational or toxicological effects on the body or organ weights, food consumption, hematology and biochemistry at dose 6 mg/kg bw. However, vitacoxib (30 mg/kg) showed minor alterations to histopathology of liver, kidney and stomach related to treatment. These results provide further indication that vitacoxib is safe and well tolerated in rats after 180 days of daily oral administration at 6 mg/kg bw and the NOAEL for both sexes was 6 mg/kg bw for 180 consecutive days. PMID- 29601911 TI - Neuroprotective effect of the carnosine - alpha-lipoic acid nanomicellar complex in a model of early-stage Parkinson's disease. AB - In a model of early-stage Parkinson's disease induced by a single intranasal administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to Wistar rats, a neuroprotective effect of a new derivative of carnosine and alpha-lipoic acid (C/LA nanomicellar complex) was demonstrated. Acute intraperitoneal administration of carnosine, alpha-lipoic acid and C/LA complex following MPTP administration normalized the total antioxidant activity in the brain tissue. Of all the compounds tested only C/LA complex normalized the metabolism of dopamine (DA) and serotonin (5-HT), while its components did not show similar effects when used separately. C/LA complex effectively restored the level of DA metabolites: the level of DOPAC was increased by 24.7 +/- 5.6% compared to the animals that had received MPTP only, and the level of HVA was restored to the values observed in the intact animals. Integral metabolic indices of DA (DOPAC/DA and HVA/DA ratios) and 5-HT turnover (5-HIAA/5-HT ratio) in the striatum tended to increase in case of C/LA complex administration. PMID- 29601912 TI - Residue behavior and dietary intake risk assessment of carbosulfan and its metabolites in cucumber. AB - The residue behavior and dietary intake risks of carbosulfan and its metabolites in cucumbers were investigated. A quick and reliable method for determining carbosulfan and its metabolite residues in cucumbers was established using ultrahigh performance liquid chromatography-tandem mass spectrometry. The fortified recoveries ranged from 87.2% to 91.0% with relative standard deviations of 3.2%-8.1%. The dissipation results showed that carbosulfan was transformed into carbofuran and 3-hydroxy carbofuran in cucumbers. The half-life of carbosulfan was 1.5 days, and the half-life of carbofuran was 45 days. The final residues of carbosulfan varied from 0.245 to 0.005 mg/kg and carbofuran varied from 0.123 to 0.008 mg/kg. After a 5-day application period the residues of carbosulfan was 0.113 mg/kg that was below the maximum residue limit set by China (0.2 mg/kg), and the residues of carbofuran was 0.055 mg/kg that was higher than the maximum residue limit set by China (0.02 mg/kg). The risk assessment results indicated that the dietary intake risks of carbosulfan and carbofuran from cucumber consumption were safe for Chinese consumers, but pre-harvest intervals should be strictly recommended for 7 days at the recommended dose to ensure that food quality conforms to the MRL standard. This study provides a method and data for scientifically evaluating dietary intake risks of carbosulfan and its more toxic metabolites. PMID- 29601913 TI - Fasting serum amino acids concentration is associated with insulin resistance and pro-inflammatory cytokines. AB - AIMS: We evaluated specific alterations in amino acids (AAs) profile in patients with type 2 diabetes mellitus (T2DM) and impaired fasting glucose (IFG) compared with healthy controls. In addition, we tried to find the mechanisms behind these AA alterations. METHODS: Twenty AAs, TNF-alpha, and IL-6 were analyzed in fasting serum samples from a total of 198 individuals (56 drug-naive patients with T2DM, 69 patients IFG, and 73 healthy controls). The C2C12 mouse myoblast cell lines were used to examine the changes of MAFbx and MuRF1 expressions, which are muscle specific E3 ligases acting as major mediators of skeletal muscle proteolysis, after development of insulin resistance induced by palmitate treatment. RESULTS: In addition to branched chain amino acids BCAAs, fasting serum AAs such as glutamic acid, lysine, phenylalanine, arginine, alanine, tyrosine, aspartic acid, were higher in patients with T2DM and intermediately elevated in patients with IFG compared with normoglycemic controls. These serum AA concentrations positively correlated with fasting glucose, homeostasis model assessment of insulin resistance (HOMA-IR), and pro-inflammatory cytokines. In addition, HOMA IR and pro-inflammatory cytokines were two important independent predictors of serum AA levels. In vitro experiments showed that palmitate treatment in C2C12 myotubes induced insulin resistance, increased pro-inflammatory cytokine gene expression, and increased MAFbx gene and protein expression. CONCLUSIONS: The increase in fasting serum AAs can be an early manifestation of insulin resistance. Increased muscle proteolysis induced by insulin resistance and inflammatory cytokines can be a possible mechanism for the rise in serum AA levels. PMID- 29601914 TI - The association between pre-pregnancy impaired fasting glucose and adverse perinatal outcome. AB - AIMS: To evaluate the association between impaired fasting glucose (IFG) prior to pregnancy with maternal and neonatal outcome. METHODS: A retrospective cohort study of singleton deliveries in a single, tertiary, university-affiliated medical center between August 2007 and December 2012. We included women who had a fasting glucose test done up to 26 weeks prior to pregnancy. We excluded women with diabetes mellitus and women carrying a fetus with structural or chromosomal anomalies. Maternal and neonatal outcome were compared between two groups: women with pre-pregnancy IFG (defined as fasting glucose >=100 mg/dl and <126 mg/dl) versus those with normoglycemia (fasting glucose <100 mg/dl). RESULTS: Overall, 1945 women met inclusion criteria. Of whom, 1790 had pre-pregnancy glucose <100 mg/dl and 155 had IFG. There were no differences between groups in basic characteristics. As for maternal outcome, IFG was associated with higher rates of mild preeclampsia (5.16% vs. 0.67%), abnormal glucose challenge test (21.94% vs. 13.46%) and gestational diabetes (13.55 vs. 2.85%), p < 0.05 for all. There were no significant differences in neonatal outcome. After adjusting for potential confounders, on multivariable logistic regression, pre-pregnancy IFG remained significantly and independently associated with mild preeclampsia (aOR 6.92, 95% CI 2.68-18.05, p < 0.001). CONCLUSIONS: Pre-pregnancy IFG is associated with increased risk for abnormal glucose challenge test and gestational diabetes, and it is an independent risk factor for adverse pregnancy outcome including mild preeclampsia. PMID- 29601915 TI - Effect of the economic crisis on the use of health and home care services among elderly Spanish diabetes patients. AB - AIMS: To describe the utilization of health and home care services among older people (>=65 years) with diabetes during the economic crisis; to identify the factors associated with changes in the utilization of these services; and to study the time trends (2009-2014). METHODS: We used the European Health Interview Surveys for Spain (EEHSS) for 2009/10 and 2014. The dependent variables included self-reported hospitalizations; general practitioner (GP) visits; 'other healthcare services' (OHS) used; and home care services (HCS) used. RESULTS: We identified 6026 and 6020 diabetic patients (EEHSS2009 and EEHSS2014, respectively). A significant decrease in the number of GP visits (OR 0.94; 95% CI 0.91-0.98) and the use of HCS (OR 0.95; 95% CI 0.91-0.99) was found; however, we found an increase in the use of OHS (OR 1.06; 95% CI 1.02-1.10). Multivariate models showed that factors associated with an increased use included chronic conditions, worse self-rated health, pain and mental disorders. Physical activity was a strong predictor of lower hospitalizations and HCS use. Female gender was associated with significantly lower hospitalizations and a higher use of OHC and HCS. CONCLUSION: We found a decrease in the number of GP visits and the use of HCS among elderly diabetic adults; however, we also observed an increase in the use of OHS, which may partly explain this decrease in the figures. Significant differences in the use of health services were found according to gender. The effect of the economic crisis, if any, seems to have had a small magnitude. PMID- 29601916 TI - B-RCA revealed circulating miR-33a/b associates with serum cholesterol in type 2 diabetes patients at high risk of ASCVD. AB - AIMS: Type 2 diabetes (T2D) is a complex metabolic disease with high incidence throughout the world. Dyslipidemia is the leading cause of atherosclerotic cardiovascular diseases (ASCVD) in T2D patients. hsa-miR-33 (miR-33) serves as a regulator in lipid metabolism. We hypothesized that blood miR-33 associates with serum lipids in T2D patients at high risk of ASCVD events. METHODS: We developed a branched rolling circle amplification (B-RCA) method and assessed its sensitivity and specificity with miR-33a/b standards by traditional TaqMan assay. Circulating miR-33a/b level was then determined with B-RCA in 30 T2D patients at high risk for developing ASCVD and 33 healthy controls. Pearson correlation coefficient was used to evaluate the correlation between circulating miR-33a/b and serum cholesterol. RESULTS: Compared with TaqMan assay, B-RCA method showed a similar specificity and a 100-fold higher sensitivity for miR-33a detection. Circulating miR-33a/b level is positively correlated with serum total cholesterol (TC) (r = 0.364, p = 0.048) and low-density lipoprotein cholesterol (LDL-C) (r = 0.383, p = 0.037) in T2D patients at high risk for developing ASCVD. CONCLUSIONS: Our B-RCA method provided an alternative strategy with specificity and high sensitivity for circulating miRNAs detection, and the results demonstrated that miR-33a/b might play an important role in cholesterol regulation. PMID- 29601917 TI - Measuring feeding difficulties in toddlers with Down syndrome. AB - Early feeding problems occur frequently across the population, but have a higher incidence in children with Down syndrome (DS). Early identification can possibly be improved with the help of a valid screening instrument based on caregiver reports. In a previous study, we investigated the concurrent validity of the Dutch version of the Montreal Children's Hospital Feeding Scale (MCH-FS, SEP in Dutch) in a sample of typically developing toddlers, and we found a correlation between the score on the instrument and observed behavior during a regular meal. The current pilot study was a replication in a sample of children with DS (aged 1; 0-3; 0) and their primary caregivers (n = 32). The results showed that children in the sample did not score higher on the SEP than children in their respective norm groups. In addition, when caregivers reported more symptoms of feeding problems on the SEP, children showed more food refusal and negative affect during the observed meal. This suggests that the screening instrument is particularly associated with negative mealtime interactions. This is in contrast with earlier results, which mainly indicated a relation with eating skills. PMID- 29601918 TI - Effects of left dlPFC modulation on social cognitive processes following food sampling. AB - BACKGROUND: The dorsolateral prefrontal cortex (dlPFC) plays a central role in the inhibition of eating, but also the modulation of conscious thought processes that might precede, accompany or follow initial food tasting. The latter might be particularly important to the extent that post-tasting cognitions may drive prolonged eating beyond the satiety point. However, we know very little about the effect of the dlPFC on conation following initial food sampling. This investigation compared the effects of dlPFC attenuation using repetitive transcranial magnetic stimulation (rTMS) on social cognition following (Study 1) and prior to (Study 2) a food consumption opportunity. METHODS: In Study 1, participants (N = 21; Mage = 21 years) were randomized to active or sham continuous theta-burst stimulation (cTBS; an inhibitory variant of rTMS) targeting the left dlPFC followed by an interference task. Participants subsequently completed measures of attitudes, norms and perceived control following a mock taste test. In Study 2, a second sample of right handed participants (N = 37; Mage = 21 years) were assigned to active or sham cTBS, followed by an interference task and two measures of attitudes (implicit and explicit), both assessed prior to the same taste test paradigm. RESULTS: In Study 1, findings revealed a reliable effect of cTBS on post-tasting attitudes (t(1,19) = 3.055, p = .007; d = 1.34), such that attitudes towards calorie dense snack foods were significantly more positive following active stimulation than following sham stimulation. Similar effects were found for social norms (t(1,19) = 3.024, p = .007, d = 1.31) and perceived control (t(1,20) = 19.247, p < .001, d = 0.50). In Study 2, no effects of cTBS were observed on pre-consumption attitudes, despite reliable effects on interference scores and subsequent consumption. CONCLUSIONS: The left dlPFC may selectively modulate facilitative social cognition following initial food sampling (but not pre-consumption). PMID- 29601919 TI - Parent-child health- and weight-focused conversations: Who is saying what and to whom? AB - The purpose of this study was to examine the prevalence of health-focused (healthy eating, physical activity) and weight-focused (weight, dieting) parent child conversations, and to understand who is talking and who is listening, by exploring the associations these conversations have with parent and child characteristics. The study population included 546 parents (age 27-36 years) who participated in Project EAT (Eating and Activity in Teens and Young Adults)-IV (2015-2016) and had a child aged 2-17 years. Cross-sectional prevalence ratios were calculated to identify associations between parent and child characteristics and the parent-child conversations. Conversations about healthy eating (82%) and physical activity (75%) were more prevalent than those about the child's weight (30%), and dieting (25%). In adjusted models, parents meeting physical activity recommendations had a higher prevalence of health-focused conversations (healthy eating PR = 1.10, 95% CI = 1.01, 1.20; physical activity PR = 1.12, 95% CI = 1.02, 1.24); whereas, weight-focused conversations were more common among parents who had recently dieted and perceived their child to be overweight. Health focused and weight-focused conversations were highly common among the oldest children aged 9-17 years (health-focused = 90-93% and weight-focused = 42-53%); though, a substantial prevalence of health- and weight-focused conversations (>50% and >=10%, respectively) also occurred with the youngest children (2-4 years). Findings suggest that parent-child health- and weight-focused conversations are common and that characteristics, including child's age and parents' physical activity, dieting, and perceptions of child weight, may be useful to consider in public health messaging, interventions, and family education that address parent-child communication. PMID- 29601921 TI - The family child care home environment and children's diet quality. AB - BACKGROUND: Developing healthy eating behaviors and food preferences in early childhood may help establish future healthy diets. Large numbers of children spend time in child care, but little research has assessed the nutritional quality of meals and snacks in family child care homes. Therefore, it is important to assess foods and beverages provided, policies related to nutrition and feeding children, and interactions between providers and children during mealtimes. We examined associations between the nutrition environments of family child care homes and children's diet quality. METHODS: We assessed the nutrition environments of 166 family child care homes using the Environment and Policy Assessment and Observation (EPAO) (scores range: 0-21). We also recorded foods and beverages consumed by 496 children in care and calculated healthy eating index (HEI) (scores range: 0-100). We used a mixed effects linear regression model to examine the association between the EPAO nutrition environment (and EPAO sub-scales) and child HEI, controlling for potential confounders. RESULTS: Family child care homes had a mean (standard deviation, SD) of 7.2 (3.6) children in care, 74.1% of providers were black or African American, and children had a mean (SD) age of 35.7 (11.4) months. In adjusted multivariable models, higher EPAO nutrition score was associated with increased child HEI score (1.16; 95% CI: 0.34, 1.98; p = 0.006). Higher scores on EPAO sub-scales for foods provided (8.98; 95% CI: 3.94, 14.01; p = 0.0006), nutrition education (5.37; 95% CI: 0.80, 9.94; p = 0.02), and nutrition policy (2.36; 95% CI: 0.23, 4.49; p = 0.03) were all associated with greater child HEI score. CONCLUSIONS: Foods and beverages served, in addition to nutrition education and nutrition policies in family child care homes, may be promising intervention targets for improving child diet quality. PMID- 29601920 TI - Eating with others and meal location are differentially associated with nutrient intake by sex: The Diabetes Study of Northern California (DISTANCE). AB - Though eating with others is often a social behavior, relationships between social contexts of eating and nutrient intake have been underexplored. This study evaluates how social aspects of eating - frequencies of eating meals with others, meals prepared at home, and meals outside the home - are associated with nutrient intake. Because diet improvement can reduce complications of diabetes mellitus, we surveyed a multi-ethnic cohort of persons with type 2 diabetes (n = 770) about social aspects of diet (based on 24-hour recalls). Sex-stratified multiple regression analyses adjusted for confounders assessed the relationship between frequency of eating with others and nutrient intake (total energy, energy from fat, energy from carbohydrates, Healthy Eating Index/HEI, Dietary Approaches to Stop Hypertension/DASH score). Although there was slight variation in men's versus women's propensity to share meals, after adjustment for confounders, there was no consistently significant association between meals with others and the 5 nutrient intake measures for either men or women. The directions of association between categories of eating with others and diet quality (HEI and DASH scores) - albeit not significant - were different for men (positive) and women (mostly negative), which warrants further investigation. The next analyses estimated nutrient intake associated with meals prepared at home, and meals consumed outside the home. Analyses indicated that greater meal frequency at home was associated with significantly better scores on diet quality indices for men (but not women), while meal frequency outside the home was associated with poorer diet quality and energy intake for women (but not men). Better measurement of social dimensions of eating may inform ways to improve nutrition, especially for persons with diabetes for whom diet improvement can result in better disease outcomes. PMID- 29601922 TI - Family food involvement is related to healthier dietary intake in preschool-aged children. AB - Children in the United States fall far short of meeting federal dietary recommendations. The unhealthy diets common amongst young children are of crucial public health concern, given that they can inhibit healthy development and are predictive of chronic diseases in adulthood. Research investigating behaviors that are related to dietary habits is crucial to allow a better understanding of the causes of unhealthy dietary practices. Involvement in food preparation is known to be associated with healthy dietary behaviors in school-aged children, but little is known about these behaviors and their correlates in younger children. The present study sought to examine the influences and correlates of involvement in family food preparation in children at ages three and four. Parents of preschool aged children (n = 497) completed surveys including information about demographic background, their children's family food involvement, dietary intake, mealtime routines, and problematic eating behaviors. Data were collected when children were three (wave one of the survey) and four years of age (wave two). Findings from this study indicate that family food involvement at age three is predictive of healthier dietary intake at age four (increased consumption of fruits and vegetables, decreased consumption of fast food). These findings indicate that family food involvement is predictive of healthier dietary behaviors in young children, and that outreach efforts focused on family food involvement in early childhood may improve children's dietary habits. PMID- 29601923 TI - Evaluation and Management of Testosterone Deficiency: AUA Guideline. AB - PURPOSE: There has been a marked increase in testosterone prescriptions in the past decade resulting in a growing need to give practicing clinicians proper guidance on the evaluation and management of the testosterone deficient patient. MATERIALS AND METHODS: A systematic review utilized research from the Mayo Clinic Evidence Based Practice Center and additional supplementation by the authors. Evidence-based statements were based on body of evidence strength Grade A, B, or C and were designated as Strong, Moderate, and Conditional Recommendations with additional statements presented in the form of Clinical Principles or Expert Opinions (table 1 in supplementary unabridged guideline, http://jurology.com/). RESULTS: This guideline was developed by a multi-disciplinary panel to inform clinicians on the proper assessment of patients with testosterone deficiency and the safe and effective management of men on testosterone therapy. Additional statements were developed to guide the clinician on the appropriate care of patients who are at risk for or have cardiovascular disease or prostate cancer as well as patients who are interested in preserving fertility. CONCLUSIONS: The care of testosterone deficient patients should focus on accurate assessment of total testosterone levels, symptoms, and signs as well as proper on-treatment monitoring to ensure therapeutic testosterone levels are reached and symptoms are ameliorated. Future longitudinal observational studies and clinical trials of significant duration in this space will improve diagnostic techniques and treatment of men with testosterone deficiency as well as provide more data on the adverse events that may be associated with testosterone therapy. PMID- 29601924 TI - Anterior Urethroplasty Using a New Tissue Engineered Oral Mucosa Graft: Surgical Techniques and Outcomes. AB - PURPOSE: We investigated whether tissue engineered material may be adopted using standard techniques for anterior urethroplasty. MATERIALS AND METHODS: We performed a retrospective multicenter study in patients with recurrent strictures, excluding those with failed hypospadias, lichen sclerosus, traumatic and posterior strictures. A 0.5 cm2 oral mucosa biopsy was taken from the patient cheek and sent to the laboratory to manufacture the graft. After 3 weeks the tissue engineered oral mucosal MukoCell(r) graft was sent to the hospital for urethroplasty. Four techniques were used, including ventral onlay, dorsal onlay, dorsal inlay and a combined technique. Cystourethrography was performed 1 month postoperatively. Patients underwent clinical evaluation, uroflowmetry and post void residual urine measurement every 6 months. When the patient showed obstructive symptoms, defined as maximum urine flow less than 12 ml per second, the urethrography was repeated. Patients who underwent further treatment for recurrent stricture were classified as having treatment failure. RESULTS: Of the 38 patients with a median age of 57 years who were included in study the strictures were penile in 3 (7.9%), bulbar in 29 (76.3%) and penobulbar in 6 (15.8%). Median stricture length was 5 cm and median followup was 55 months. Treatment succeeded in 32 of the 38 patients (84.2%) and failed in 15.8%. Success was achieved in 85.7% of ventral onlay, 83.3% of dorsal onlay, 80% of dorsal inlay and 100% of combined technique cases. No local or systemic adverse reactions due to the engineered material were noted. CONCLUSIONS: Our findings show that a tissue engineered oral mucosa graft can be implanted using the same techniques suggested for anterior urethroplasty and native oral mucosa, and guaranteeing a similar success rate.

PMID- 29601927 TI - Genetic alterations in the NO-cGMP pathway and cardiovascular risk. AB - In the past ten years, several chromosomal loci have been identified by genome wide association studies to influence the risk of coronary artery disease (CAD) and its risk factors. The GUCY1A3 gene encoding the alpha1 subunit of the soluble guanylyl cyclase (sGC) resides at one of these loci and has been strongly associated with blood pressure and CAD risk. More recently, further genes in the pathway encoding the endothelial nitric oxide synthase, the phosphodiesterases 3A and 5A, and the inositol 1,4,5-trisphosphate receptor I-associated protein (IRAG), i.e., NOS3, PDE3A, PDE5A, and MRVI1, respectively, were likewise identified as CAD risk genes. In this review, we highlight the genetic findings linking variants in NO-cGMP signaling and cardiovascular disease, discuss the potential underlying mechanisms which might propagate the development of atherosclerosis, and speculate about therapeutic implications. PMID- 29601928 TI - Biological properties of nitro-fatty acids in plants. AB - Nitro-fatty acids (NO2-FAs) are formed from the reaction between nitrogen dioxide (NO2) and mono and polyunsaturated fatty acids. Knowledge concerning NO2-FAs has significantly increased within a few years ago and the beneficial actions of these species uncovered in animal systems have led to consider them as molecules with therapeutic potential. Based on their nature and structure, NO2-FAs have the ability to release nitric oxide (NO) in aqueous environments and the capacity to mediate post-translational modifications (PTM) by nitroalkylation. Recently, based on the potential of these NO-derived molecules in the animal field, the endogenous occurrence of nitrated-derivatives of linolenic acid (NO2-Ln) was assessed in plant species. Moreover and through RNA-seq technology, it was shown that NO2-Ln can induce a large set of heat-shock proteins (HSPs) and different antioxidant systems suggesting this molecule may launch antioxidant and defence responses in plants. Furthermore, the capacity of this nitro-fatty acid to release NO has also been demonstrated. In view of this background, here we offer an overview on the biological properties described for NO2-FAs in plants and the potential of these molecules to be considered new key intermediaries of NO metabolism in the plant field. PMID- 29601929 TI - 6-OHBDE-47 induces transcriptomic alterations of CYP1A1, XRCC2, HSPA1A, EGR1 genes and trigger apoptosis in HepG2 cells. AB - In this study, HepG2 cells were exposed to 6-hydroxy- 2,2',4,4' tetrabromodiphenyl ether (6-OH-BDE-47) for 3 and 6 days for monitoring cytotoxic effects and alterations in its transcriptomic profile. MTT assay showed that cells exposed to 6-OH-BDE-47 (50 nM) exhibited 48.5% and 53.7% decline in cell survival after 3 and 6 days. Neutral red uptake (NRU) assay also demonstrated 47.1% and 56% reduction in cell survival at 50 nM, indicating lysosomal toxicity. The flow cytometric data confirmed an increase in intracellular reactive oxygen species (ROS) and mitochondrial dysfunction (DeltaPsim). In comet assay, HepG2 cells exposed to 6-OH-BDE-47 (50 nM) showed 7.6-fold greater DNA damage. Cell cycle data revealed G2/M arrest at 10 and 25 nM after 3 days of exposure, while 50 nM induced mild apoptotic effect. The intensity of apoptosis increased after 6 days of exposure with 21.5%, 47% and 99.1% of cells recorded in subG1 apoptotic phase vis-a- vis the control showed 14.5% background apoptotic cells. Transcriptome analysis of 6-OH-BDE-47 (25 nM, 3 days) treated cells revealed cross talk between vital pathways. Especially, the genes involved in oxidative or metabolic stress, heat shock, growth arrest and senescence were differentially up and down regulated to orchestrate the cellular toxicity and triggering apoptosis in HepG2 cells. PMID- 29601930 TI - Liposome-supported peritoneal dialysis in the treatment of severe hyperammonemia: An investigation on potential interactions. AB - Peritoneal dialysis (PD) performed with transmembrane pH-gradient liposomes was reported to efficiently remove ammonia from the body, representing a promising alternative to current standard-of-care for patients with severe hepatic encephalopathy. In this study, we further characterized the properties of liposome-supported peritoneal dialysis (LSPD) by 1) assessing its in-use stability in the presence of ascitic fluids from liver-disease patients; 2) investigating its interactions with drugs that are commonly administered to acute on-chronic liver failure patients; and 3) analyzing the in vivo extraction profile of LSPD. We found that LSPD fluid maintained its in vitro ammonia uptake capability when combined with ascitic fluids. The co-incubation of selected drugs (e.g., beta-blockers, antibiotics, diuretics) with LSPD fluids and ammonia resulted in limited interaction effects for most compounds except for two fluoroquinolones and propranolol. However, considering the experimental set-up, these results should be interpreted with caution and confirmatory drug-drug interaction studies in a clinical setting will be required. Finally, metabolite mapping analysis on dialysates of LSPD-treated rats revealed that the liposomes did not remove important metabolites more than a conventional PD fluid. Overall, these findings confirm that LSPD is a potentially safe and effective approach for treating hyperammonemic crises in the context of acute-on-chronic liver failure. PMID- 29601931 TI - Systems for localized release to mimic paracrine cell communication in vitro. AB - Paracrine cell communication plays a pivotal role for signal exchange between proximal cells in vivo. However, this localized, gradient type release of mediators at very low concentrations (pg/ml), relevant during physiological and pathological processes, is rarely reflected within in vitro approaches. This review gives an overview on state-of-the-art approaches, which transfer the paracrine cell-to-cell communication into in vitro cell culture model setups. The traditional methods like trans-well assays and more advanced microfluidic approaches are included. The review focusses on systems for localized release, mostly based on microparticles, which tightly mimic the paracrine interaction between single cells in 3D microenvironments. Approaches based on single microparticles, with the main focus on affinity-controlled storage and release of cytokines, are reviewed and their importance for understanding paracrine communication is highlighted. Various methods to study the cytokine release and their advantages and disadvantages are discussed. Basic principles of the release characteristics, like diffusion mechanisms, are quantitatively described, including the formation of resulting gradients around the local sources. In vitro cell experiments using such localized microparticle release systems in approaches to increase understanding of stem cell behavior within their niches and regulation of wound healing are highlighted as examples of successful localized release systems for mimicking paracrine cell communication.

PMID- 29601932 TI - Sequential intracellular release of water-soluble cargos from Shell-crosslinked polymersomes. AB - Polymer vesicles, i.e. polymersomes (PS), present unique nanostructures with an interior aqueous core that can encapsulate multiple independent cargos concurrently. However, the sequential release of such co-loaded actives remains a challenge. Here, we report the rational design and synthesis of oxidation responsive shell-crosslinked PS with capability for the controlled, sequential release of encapsulated hydrophilic molecules and hydrogels. Amphiphilic brush block copolymers poly(oligo(ethylene glycol) methyl ether methacrylate)-b poly(oligo(propylene sulfide) methacrylate) (POEGMA-POPSMA) were prepared to fabricate PS via self-assembly in aqueous solution. As a type of unique drug delivery vehicle, the interior of the PS was co-loaded with hydrophilic molecules and water-soluble poly(N-isopropylacrylamide) (PNIPAM) conjugates. Due to the thermosensitivity of PNIPAM, PNIPAM conjugates within the PS aqueous interior underwent a phase transition to form hydrogels in situ when the temperature was raised above the lower critical solution temperature (LCST) of PNIPAM. Via control of the overall shell permeability by oxidation, we realized the sequential release of two water-soluble payloads based on the assumption that hydrogels have much smaller membrane permeability than that of molecular cargos. The ability to control the timing of release of molecular dyes and PNIPAM-based hydrogels was also observed within live cells. Furthermore, leakage of hydrogels from the PS was effectively alleviated in comparison to molecular cargos, which would facilitate intracellular accumulation and prolonged retention of hydrogels within the cell cytoplasm. Thus, we demonstrate that the integration of responsive hydrogels into PS with crosslinkable membranes provides a facile and versatile technique to control the stability and release of water-soluble cargos for drug delivery purposes.

PMID- 29601935 TI - A healthy diet in women is associated with less facial wrinkles in a large Dutch population-based cohort. AB - BACKGROUND: Little is known about the effects of different dietary patterns on facial wrinkling. OBJECTIVE: We aimed to investigate the association between diet and facial wrinkles in a population-based cohort of 2,753 elderly participants of the Rotterdam Study. METHODS: Wrinkles were digitally quantified as the area in facial photographs they occupied as a percentage of the total skin area. Diet was assessed using the Food Frequency Questionnaire. Adherence to the Dutch Healthy Diet Index (DHDI) was calculated. In addition, we used Principal Component Analysis (PCA) to extract relevant food patterns in men and women separately. All food patterns and the DHDI were analyzed for association with wrinkle severity using multivariable linear regression. RESULTS: Better adherence to the Dutch guidelines was significantly associated with less wrinkles among women but not in men. In women, a red meat and snack dominant PCA pattern was associated with more facial wrinkles whereas a fruit dominant PCA pattern associated with fewer wrinkles. LIMITATIONS: Due to the cross-sectional design of our study, no causation can be proved. Health-conscious behavior could have influenced our results. CONCLUSION: Dietary habits associate with facial wrinkling in women. Global disease prevention strategies might benefit from emphasizing that a healthy diet is also linked to less facial wrinkling.

PMID- 29601937 TI - Subungual atypical lentiginous melanocytic proliferations in children and adolescents: A clinicopathologic study. AB - BACKGROUND: Most subungual melanocytic lesions in children are benign, but some are difficult to classify due to prominent lentiginous growth and high-grade cytologic atypia. OBJECTIVE: To characterize the clinicopathologic features of these rare lesions. METHODS: Subungual atypical lentiginous melanocytic proliferations from patients <20 years of age were collected for clinical and histopathologic review. Fluorescence in situ hybridization (FISH) was performed when possible. RESULTS: Eleven patients aged 2-19 years had expanding or darkening longitudinal pigmented streak(s) with or without Hutchinson sign. Microscopically, all revealed predominantly single-cell growth, pagetoid scatter, and poor circumscription. Eight (73%) cases showed focal or poor nesting, and 3 (27%) demonstrated confluence. Nuclear enlargement, hyperchromasia, and angulation were present in 8 (73%) cases, 7 (64%) cases, and 6 (55%) cases, respectively. One of 4 cases tested by FISH was positive. Three lesions recurred locally without other adverse outcome. LIMITATIONS: Small sample size and short clinical follow-up. Two cases were examined in partial biopsies only. CONCLUSION: Some subungual melanocytic lesions in children and adolescents are histologically indistinguishable from adult subungual melanoma in situ. While the biologic potential remains elusive, FISH might aid in risk stratification. Awareness of this rare group of lesions is crucial for facilitating future investigation into its biologic behavior. PMID- 29601938 TI - Gene silencing of ZnT8 attenuates inflammation and protects pancreatic tissue injury in T1D. AB - T lymphocyte mediated inflammation contributes to the development of T1D. Zinc Transporter 8 (ZnT8) has emerged as a target of autoreactive T cells in human T1D in recent years. However, the regulating of ZnT8 in T1D has not been identified. We make a hypothesis that whether alternation of ZnT8 level could attenuate inflammation and protect pancreatic tissue injury in T1D. In this study, we utilized ZnT8 shRNA to inhibit ZnT8 expression, and detected inflammation, glucose tolerance and pancreatic tissue of NOD mice. We found that ZnT8 shRNA attenuated specific CD8+ T cell activation and cytotoxicity. In addition, ZnT8 shRNA protected glucose tolerance and pancreatic tissue injury via down regulation of ZnT8 in NOD mice. Therefore, the results suggest that RNAi represents a promising target reducing ZnT8 mediated inflammation, and provides a novel therapeutical clue in T1D. PMID- 29601939 TI - DEC1/STRA13 is a key negative regulator of activation-induced proliferation of human B cells highly expressed in anergic cells. AB - The transcription factor DEC1/STRA13 (also known as BHLHE40 and SHARP2) is involved in a number of processes including inhibition of cell proliferation and delay of cell cycle, and is a negative regulator of B cell activation and development in mice. We show here that, unlike in mice, DEC1/STRA13 expression is induced in human naive and memory resting B cells by activation through the B cell receptor (BCR) or Toll-like receptor 9 (TLR9). siRNA silencing of DEC1/STRA13 increases the capacity of activated B cells to perform a high number of divisions after TLR9 ligation. This identifies DEC1/STRA13 as a critical negative regulator of clonal expansion of activated human B cells. We also show that DEC1/STRA13 is upregulated in human anergic CD21low B cells clonally expanded in patients with HCV-associated mixed cryoglobulinemia, which fail to proliferate in response to BCR or TLR9 ligation. siRNA knockdown of DEC1/STRA13, however, fails to restore responsiveness to stimuli in these cells, although it might improve the proliferative capacity in a subset of anergic cells with less pronounced proliferative defect.

AB - Pertussis, or whooping cough, has recently reemerged as a major public health threat despite high levels of vaccination. The development of a novel pertussis vaccine, especially an intranasal (i.n.) vaccine is undoubtedly necessary, and mucosal adjuvants have been explored to enhance the immune response. In the present study, bacterium-like particles (BLPs) were adopted as a mucosal adjuvant for an i.n. pertussis vaccine and evaluated on the ability to induce serum and mucosal antibodies as well as potency against i.n. challenge in mice. Groups with or without aluminum adjuvant were also evaluated through both i.n. and intraperitoneal inoculations. Vaccination with BLPs via the i.n. route led to rapid IgG and IgA production and provided strong protection against inflammation induced by infection. The results support an i.n. pertussis vaccine with BLPs adjuvant as a promising candidate to elicit protective immunity against whooping cough.

AB - Immune dysregulation is a central process in the pathogenesis of systemic sclerosis (SSc). Cytokines produced by lymphocytes and monocytes are important mediators and induce tissue damage, recruit additional inflammatory cells, and promote extracellular matrix production and fibrosis. In the present research, we aimed to study the associations between levels of cytokines in serum and culture supernatants from peripheral blood mononuclear cells (PBMCs) and clinical manifestations in SSc patients. Serum samples were obtained from 56 SSc patients and 56 unrelated age- and gender-matched healthy individuals. Resting and anti CD3/CD28-stimulated PBMC cultures were obtained from 19 SSc patients and 8 healthy controls. IL-2, IL-4, IL-6, IL-10, IL-17A, TNF, and IFN-gamma levels were measured by ELISA or CBA. Serum cytokines, except IL-17A, were below the kit detection limit in most of the patients and controls. In unstimulated PBMC, the production of TNF(p = 0.004), IL-10(p = .048), IL-2(p < 0.001), and IL-6 (p = 0.01) was higher in SSc patients than in healthy controls. After anti-CD3/CD28 stimulation, scleroderma PBMCs had lower concentrations of TNF(p = 0.009), IL 10(p = .018), and IL-2(p = .002) than HC. In unstimulated PBMC, IL-2 concentration was higher in patients with esophageal dysmotility (p = 0.04), and IL-10 levels had a positive correlation with modified Rodnan score (p = 0.03). After anti-CD3/CD28 stimulation, higher levels of IL-2 and IL-4 were observed in SSc patients with lung fibrosis (p = 0.01 and 0.006, respectively), and higher levels of IL-10 (p = 0.04) and IL-4 (p = 0.04) in patients with digital ulcers. In conclusion, SSc patients have a different profile of cytokine production and this was associated with clinical manifestations. PMID- 29601942 TI - Effects of Toll-like receptor 4 on beta2-glycoprotein I-induced splenic T cell subsets differentiation. AB - Our previous study demonstrated that beta 2-glycoprotein I (beta2GPI) stimulation promotes bone marrow derived dendritic cells (BMDCs) maturation and T cell proliferation in a Toll-like receptor 4 (TLR4) dependent manner. However, beta2GPI induced T cell differentiation and the role of TLR4 in this process have rarely been reported. In the present study, we focused on the differentiation of splenic T cells in beta2GPI immunized Balb/c, C3H/HeN and C3H/HeJ mice. According to our results, Th2 dominated differentiation was observed in beta2GPI immunized Balb/c and C3H/HeN mice than in those treated with normal saline (NS), namely the up-regulated levels of Th2 markers GATA3 and IL-4 (p < 0.05). Meanwhile, reduced Th1 markers T-bet and IFN-gamma, and Treg marker Foxp3 were observed in beta2GPI immunized mice (p < 0.05). C3H/HeJ mice have the same gene background with C3H/HeN mice except a functional mutant in TLR4 gene. However, the described Th2 differentiation was not detected in these TLR4 deficient mice, indicating the importance of TLR4 in immune response against beta2GPI. In addition, we found that beta2GPI-induced Th2 differentiation could be strengthened by cytokines secreted by dendritic cells (DCs) and DCs-T cells interaction. However, DCs-T cells contact was indispensable during this process because of its unique role in suppressing Th1 function. Furthermore, this Th2 biased differentiation pattern was more noticeable in mice received 4 times beta2GPI immunization than those received 2 times, suggesting the amplifying effects of anti-beta2GPI Ab on beta2GPI induced Th2 response. These findings may partly explain the immune imbalance in APS patient through the view angle of T cell differentiation and anti-beta2GPI antibody production. PMID- 29601944 TI - Cellular players that shape evolving pathology and neurodegeneration following traumatic brain injury. AB - Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide, and has emerged as a critical risk factor for multiple neurodegenerative diseases, particularly Alzheimer's disease (AD). How the inflammatory cascade resulting from mechanical stress, axonal shearing and the loss of neurons and glia following initial impact in TBI, contributes to the development of AD-like disease is unclear. Neuroinflammation, characterized by blood-brain barrier (BBB) dysfunction and activation of brain-resident microglia and astrocytes, resulting in secretion of inflammatory mediators and subsequent recruitment of peripheral immune cells has been the focus of extensive research in attempts to identify drug-targets towards improving functional outcomes post TBI. While knowledge of intricate cellular interactions that shape lesion pathophysiology is incomplete, a major limitation in the field is the lack of understanding of how distinct cell types differentially alter TBI pathology. The aim of this review is to highlight functional differences between populations of bone marrow derived, infiltrating monocytes/macrophages and brain-resident microglia based on differential expression of the chemokine receptors CCR2 and CX3CR1. This review will focus on how unique subsets of mononuclear phagocytes shape TBI pathophysiology, neurotoxicity and BBB function, in a disease-stage dependent manner. Additionally, this review summarizes the role of multiple microglia and macrophage receptors, namely CCR2, CX3CR1 and Triggering Receptor Expressed on Myeloid Cells-2 (TREM2) in pathological neuroinflammation and neurodegeneration vs. recovery following TBI. TREM2 has been implicated in mediating AD-related pathology, and variants in TREM2 are particularly important due to their correlation with exacerbated neurodegeneration. Finally, this review highlights behavioral outcomes associated with microglial vs. macrophage variances, the need for novel treatment strategies that target unique subpopulations of peripheral macrophages, and the importance of development of therapeutics to modulate inflammatory functions of brain-resident microglia at specific stages of TBI. PMID- 29601945 TI - Hypoxia, oxidative stress and inflammation. AB - Inflammatory Arthritis is characterized by synovial proliferation, neovascularization and leukocyte extravasation leading to joint destruction and functional disability. Efficiency of oxygen supply to the synovium is poor due to the highly dysregulated synovial microvasculature. This along with the increased energy demands of activated infiltrating immune cells and inflamed resident cells leads to an hypoxic microenvironment and mitochondrial dysfunction. This favors an increase of reactive oxygen species, leading to oxidative damage which further promotes inflammation. In this adverse microenvironment synovial cells adapt to generate energy and switch their cell metabolism from a resting regulatory state to a highly metabolically active state which allows them to produce essential building blocks to support their proliferation. This metabolic shift results in the accumulation of metabolic intermediates which act as signaling molecules that further dictate the inflammatory response. Understanding the complex interplay between hypoxia-induced signaling pathways, oxidative stress and mitochondrial function will provide better insight into the underlying mechanisms of disease pathogenesis. PMID- 29601943 TI - Lung-injury depresses glutamatergic synaptic transmission in the nucleus tractus solitarii via discrete age-dependent mechanisms in neonatal rats. AB - Transition periods (TPs) are brief stages in CNS development where neural circuits can exhibit heightened vulnerability to pathologic conditions such as injury or infection. This susceptibility is due in part to specialized mechanisms of synaptic plasticity, which may become activated by inflammatory mediators released under pathologic conditions. Thus, we hypothesized that the immune response to lung injury (LI) mediated synaptic changes through plasticity-like mechanisms that depended on whether LI occurred just before or after a TP. We studied the impact of LI on brainstem 2nd-order viscerosensory neurons located in the nucleus tractus solitarii (nTS) during a TP for respiratory control spanning (postnatal day (P) 11-15). We injured the lungs of Sprague-Dawley rats by intratracheal instillation of Bleomycin (or saline) just before (P9-11) or after (P17-19) the TP. A week later, we prepared horizontal slices of the medulla and recorded spontaneous and evoked excitatory postsynaptic currents (sEPSCs/eEPSCs) in vitro from neurons in the nTS that received monosynaptic glutamatergic input from the tractus solitarii (TS). In rats injured before the TP (pre-TP), neurons exhibited blunted sEPSCs and TS-eEPSCs compared to controls. The decreased TS eEPSCs were mediated by differences in postsynaptic alpha-amino-3-hydroxy-5 methyl-4-isoxazolepropionic-acid receptors (AMPAR). Specifically, compared to controls, LI rats had more Ca2+-impermeable AMPARs (CI-AMPARs) as indicated by: 1) the absence of current-rectification, 2) decreased sensitivity to polyamine, 1 Naphthyl-acetyl-spermine-trihydrochloride (NASPM) and 3) augmented immunoreactive staining for the CI-AMPAR GluA2. Thus, pre-TP-LI acts postsynaptically to blunt glutamatergic transmission. The neuroimmune response to pre-TP-LI included microglia hyper-ramification throughout the nTS. Daily intraperitoneal administration of minocycline, an inhibitor of microglial/macrophage function prevented hyper-ramification and abolished the pre-TP-LI evoked synaptic changes. In contrast, rat-pups injured after the TP (post-TP) exhibited microglia hypo ramification in the nTS and had increased sEPSC amplitudes/frequencies, and decreased TS-eEPSC amplitudes compared to controls. These synaptic changes were not associated with changes in CI-AMPARs, and instead involved greater TS-evoked use-dependent depression (reduced paired pulse ratio), which is a hallmark of presynaptic plasticity. Thus we conclude that LI regulates the efficacy of TS -> nTS synapses through discrete plasticity-like mechanisms that are immune-mediated and depend on whether the injury occurs before or after the TP for respiratory control. PMID- 29601947 TI - Imaging the secretory compartments involved in the intracellular traffic of CHS 4, a class IV chitin synthase, in Neurospora crassa. AB - In Neurospora crassa hyphae the localization of all seven chitin synthases (CHSs) at the Spitzenkorper (SPK) and at developing septa has been well analyzed. Hitherto, the mechanisms of CHSs traffic and sorting from synthesis to delivery sites remain largely unexplored. In Saccharomyces cerevisiae exit of Chs3p from the endoplasmic reticulum (ER) requires chaperone Chs7p. Here, we analyzed the role of CSE-7, N. crassa Chs7p orthologue, in the biogenesis of CHS-4 (orthologue of Chs3p). In a N. crassa Deltacse-7 mutant, CHS-4-GFP no longer accumulated at the SPK and septa. Instead, fluorescence was retained in hyphal subapical regions in an extensive network of elongated cisternae (NEC) referred to previously as tubular vacuoles. In a complemented strain expressing a copy of cse-7 the localization of CHS-4-GFP at the SPK and septa was restored, providing evidence that CSE-7 is necessary for the localization of CHS-4 at hyphal tips and septa. CSE-7 was revealed at delimited regions of the ER at the immediacies of nuclei, at the NEC, and remarkably also at septa and the SPK. The organization of the NEC was dependent on the cytoskeleton. SEC-63, an extensively used ER marker, and NCA 1, a SERCA-type ATPase previously localized at the nuclear envelope, were used as markers to discern the nature of the membranes containing CSE-7. Both SEC-63 and NCA-1 were found at the nuclear envelope, but also at regions of the NEC. However, at the NEC only NCA-1 co-localized extensively with CSE-7. Observations by transmission electron microscopy revealed abundant rough ER sheets and distinct electron translucent smooth flattened cisternae, which could correspond collectively to the NEC, thorough the subapical cytoplasm. This study identifies CSE-7 as the putative ER receptor for its cognate cargo, the polytopic membrane protein CHS-4, and elucidates the complexity of the ER system in filamentous fungi. PMID- 29601946 TI - Calculated cell-specific intracellular hydrogen peroxide concentration: Relevance in cancer cell susceptibility during ascorbate therapy. AB - The high extracellular hydrogen peroxide (H2O2) concentrations generated during pharmacological ascorbate (P-AscH-) therapy has been shown to exhibit a high flux into susceptible cancer cells leading to a decrease in clonogenic survival. It is hypothesized that the intracellular H2O2 concentration for susceptibility is independent of cell type and that the variation observed in dosing is associated with differences in the cell-specific overall steady-state intracellular H2O2 concentration values. The steady-state variation in intracellular H2O2 concentration is coupled to a number of cellular specific transport and reaction factors including catalase activity and membrane permeability. Here a lumped parameter mathematical modeling approach, assuming a catalase-dominant peroxide removal mechanism, is used to calculate intracellular H2O2 concentration for several cell lines. Experimental measurements of critical parameters pertaining to the model are obtained. The cell lines investigated are normal pancreatic cells, H6c7, the pancreatic cancer cell line, MIA PaCa-2 and the glioblastoma cell lines, LN-229, T98G, and U-87; all which vary in susceptibility. The intracellular H2O2 concentration estimates are correlated with the clonogenic surviving fraction for each cell line, in-vitro. The results showed that, despite the fact that the experimental parameters including catalase concentration and plasma membrane permeability demonstrated significant variability across cell lines, the calculated steady-state intracellular to extracellular H2O2 concentration ratio did not vary significantly across cell lines. Thus, the calculated intracellular H2O2 concentration is not unique in characterizing susceptibility. These results imply that, although intracellular H2O2 concentration plays a key role in cellular susceptibility to P-AscH- adjuvant therapy, its overall contribution in a unifying mechanism across cell types is complex. PMID- 29601948 TI - Microarray analysis of obese women with polycystic ovary syndrome for key gene screening, key pathway identification and drug prediction. AB - PURPOSE: This study aimed to screen key genes and pathways involved in obese polycystic ovary syndrome (PCOS), and predict drugs for treatment of obese PCOS via bioinformatics approaches. METHODS: Microarray dataset GSE10946 were downloaded from the Gene Expression Omnibus database, including 7 cumulus cell samples from obese PCOS patients and 6 lean control samples. Differentially expressed genes (DEGs) between obese PCOS and controls were obtained using Bayesian test after data preprocessing, followed by functional enrichment analyses for DEGs. Besides, protein-protein interaction (PPI) network and sub network analyses were performed. Furthermore, drug prediction was carried out based on the DEGs. RESULTS: A total of 793 DEGs were identified in PCOS compared with control, including 352 up-regulated and 441 down-regulated DEGs. Specifically, upregulated RNA polymerase I subunit B (POLR1B), DNA polymerase epsilon 3, accessory subunit (POLE3), and DNA polymerase delta 3, accessory subunit (POLD3) were enriched in pathway of pyrimidine metabolism associated with obesity and PCOS, and 5-hydroxytryptamine receptor 2C (HTR2C) was enriched calcium signaling pathway. Additionally, 10 significant potential drugs, such as spironolactone targeting androgen receptor (AR), trimipramine targeting adrenoceptor beta 2 (ADRB2), and L-ornithine targeting ornithine decarboxylase antizyme 3 (OAZ3), were obtained. CONCLUSIONS: In conclusion, POLR1B, POLE3, POLD3, and HTR2C might play important roles in obese PCOS via involvement of pyrimidine metabolism and calcium signaling pathway. Moreover, AR, ADRB2, and OAZ3 might be targets of spironolactone, trimipramine, and L-ornithine in the treatment of obese PCOS. PMID- 29601949 TI - Association study of SREBF-2 gene polymorphisms and the risk of type 2 diabetes in a sample of Iranian population. AB - Type 2 diabetes mellitus (T2D) as an important metabolic disorder is accompanied by dysregulation in lipid metabolism. Sterol regulatory element-binding factor-2 (SREBF-2) gene has a substantive role in lipid metabolism. Recently published report indicated the overexpression of this gene in diabetic patients. So, in this preliminary study we evaluated the effects of three common single nucleotide polymorphisms (SNPs), rs1052717G/A, rs2267439C/T, and rs2267443G/A in risk of T2D in a sample of Iranian population. Present case-control study consists of 250 patients with endocrinologically approved T2D and 250 healthy controls. The variants genotyped by using tetra amplification refractory mutation system polymerase chain reaction (Tetra ARMS-PCR) method. The findings demonstrated that the rs2267439C/T polymorphism increased the risk of T2D in all measured inheritance models (Codominant1; p = 0.003, codominant2; p = 0.014, dominant; p < 0.0001, recessive; p = 0.037, over-dominant; p = 0.0025, and log-additive; p = 0.0048) while our results did not show statistically association between rs1052717G/A and rs2267443G/A SNPs and T2D development. The current investigation indicated that the rs2267439C/T polymorphism in the SREBF-2 gene increased the T2D susceptibility in an Iranian population. Further studies with different ethnicities and more extensive sample sizes are demanded to confirm our finding. PMID- 29601950 TI - Association between MDR1/CYP3A4/OPRM1 gene polymorphisms and the post-caesarean fentanyl analgesic effect on Chinese women. AB - OBJECTIVE: Our study aimed to evaluate the association between the multidrug resistance 1 (MDR1)/cytochrome P450 3A4 (CYP3A4)/MU-opioid receptor (OPRM1) gene polymorphisms and the post-caesarean analgesic effect of fentanyl on Chinese women. METHODS: We recruited 240 patients who received lower segment caesarean section surgeries. Sanger sequencing was used to analyze the MDR11236C > T/CYP3A4*1G/OPRM1A118G polymorphisms. We evaluated post-operative fentanyl consumption and the effect of intravenous analgesia in patients with different genotypes. RESULTS: 1. Subjects with the TT genotype at the 1236C > T polymorphism in the MDR1 gene consumed significantly more fentanyl than that consumed by subjects with the CC and CT genotypes in the first post-operative 24 h and 48 h (P < 0.05), and the MAP/HR/Cor/Ang-1 levels gradually increased immediately after surgery and in the first post-operative 24 h. 2. Subjects with the CYP3A4*1G/*1G genotype needed less fentanyl to achieve pain control than that needed by subjects carrying the CYP3A4*1/*1 and CYP3A4*1/*1G genotypes in the first post-operative 24 h and 48 h (P < 0.05), and the MAP/HR/Cor/Ang-1 levels gradually decreased immediately after surgery and in the first post-operative 24 h. 3. Subjects with the GG genotype at the A118G polymorphism in the OPRM1 gene consumed significantly more fentanyl than that consumed by subjects with the AA and AG genotypes in the first post-operative 24 h and 48 h (P < 0.05), and the MAP/HR/Cor/Ang-1 levels gradually increased immediately after surgery and in the first post-operative 24 h. 4. There were no significant differences in the adverse reactions to fentanyl in patients with different genotypes (P > 0.05). CONCLUSION: These results indicated that the MDR1/CYP3A4/OPRM1 gene polymorphisms influenced the fentanyl consumption and the physiological effects of intravenous analgesia in the Chinese women who received lower segment caesarean section surgeries. Moreover, the present study provides an important foundation and theoretical evidence for the gene-directed rationalization and individualization of medication before caesarean section surgeries. PMID- 29601951 TI - Genome-wide identification of lectin receptor kinases in pear: Functional characterization of the L-type LecRLK gene PbLRK138. AB - Lectin receptor-like kinases (LecRLKs) are membrane-bound receptors that are believed to be involved in biotic and abiotic stress responses. However, little is known about the LecRLK family in pear. In this study, a total of 172 LecRLK genes were first identified in the entire pear genome. The 172 LecRLKs were divided into three types (111 G-, 59 L- and two C-types) based on their structure and phylogenetic relationships. LecRLKs gene expressions were detected in different pear tissues including roots, stems, leaves, flowers and fruits, and the most of the 11 selected LecRLKs exhibited similar expression patterns. Furthermore, six selected LecRLKs were shown to be involved in salt stress response. Overexpression of PbLRK138, an L-type LecRLK, caused cell death and induced expression of defense-related genes in Nicotiana benthamiana. Two deletion mutants containing lectin or transmembrane and serine/threonine kinase domains did not trigger cell death. In addition, only the mutant with the transmembrane domain was localized to the plasma membrane. PMID- 29601952 TI - Muscarinic modulation of the Xenopus laevis tadpole spinal mechanosensory pathway. AB - Muscarinic acetylcholine receptors (mAChRs) mediate effects of acetylcholine (ACh) in many systems, including those involved in spinal functions like locomotion. In Xenopus laevis tadpoles at two days old, a model vertebrate for motor control research, we investigated the role of mAChRs in the skin mechanosensory pathway. We found that mAChR activation by carbachol did not affect the sensory Rohon-Beard neuron properties. However, carbachol could hyperpolarise sensory interneurons and decrease their voltage responses to outward currents. Carbachol could increase the threshold for the mechanosensory pathway to start swimming, preventing the initiation of swimming at higher concentrations altogether. Recording from the sensory interneurons in carbachol showed that their spiking after skin stimulation was depressed. However, the general muscarinic antagonist atropine did not have a clear effect on the swimming threshold or the modulation of sensory interneuron membrane conductance. Our results suggest the skin mechanosensory pathway may be subject to muscarinic modulation in this simple vertebrate system. PMID- 29601954 TI - Functional neuroimaging of recovery from motor conversion disorder: A case report. AB - A patient with motor conversion disorder presented with a functional paresis of the left hand. After exclusion of structural brain damage, she was repeatedly examined with whole-brain functional magnetic resonance imaging, while she performed visually paced finger-tapping tasks. The dorsal premotor cortex showed a bilateral deactivation in the acute-subacute phase. Recovery from unilateral hand paresis was associated with a gradual increase in task-based activation of the dorsal premotor cortex bilaterally. The right medial prefrontal cortex displayed the opposite pattern, showing initial task-based activation that gradually diminished with recovery. The inverse dynamics of premotor and medial prefrontal activity over time were found during unimanual finger-tapping with the affected and non-affected hand as well as during bimanual finger-tapping. These observations suggest that reduced premotor and increased medial prefrontal activity reflect an effector-independent cortical dysfunction in conversion paresis which gradually disappears in parallel with clinical remission of paresis. The results link the medial prefrontal and dorsal premotor areas to the generation of intentional actions. We hypothesise that an excessive 'veto' signal generated in medial prefrontal cortex along with decreased premotor activity might constitute the functional substrate of conversion disorder. This notion warrants further examination in a larger group of affected patients. PMID- 29601955 TI - The prognostic value of CHA2DS2-VASc and GRACE risk scores in patients with ACS. AB - OBJECTIVE: Cardiovascular diseases are the first cause of death in western societies. Therapeutic interventions in the individual patient should be guided by the so-called ischemic risk of this patient. PURPOSE: The aim of the study was to study the ischemic prognostic scores GRACE and CHA2DS2-VASc, in patients underwent angioplasty to highlight which best predicts better the ischemic risk. METHODS: Consecutives patients who underwent Percutaneous Coronary Intervention (PCI) due to Acute Coronary Disease, or elective PCI in one centre in Athens, Greece, where included in the study. The GRACE score and the CHA2DS2-VASc score were calculated. RESULTS: 667 patients participated in the study with an average age of 61 +/- 11 years and were followed-up for 2 years. The GRACE score and its predicted incidence at 3 years, was compared to the CHA2DS2-VASc score. CHA2DS2 VASc score was able to show a marginally better prognosis of future ischemic events, with an AUC of 0.624 vs 0.608 of the GRACE score. CONCLUSIONS: In our study, The CHA2DS2-VASc score managed to predict, marginally better, the appearance of MACCE over GRACE, in patients with angioplasty. PMID- 29601953 TI - Sulcal pits and patterns in developing human brains. AB - Spatial distribution and specific geometric and topological patterning of early sulcal folds have been hypothesized to be under stronger genetic control and are more associated with optimal organization of cortical functional areas and their white matter connections, compared to later developing sulci. Several previous studies of sulcal pit (putative first sulcal fold) distribution and sulcal pattern analyses using graph structures have provided evidence of the importance of sulcal pits and patterns as remarkable anatomical features closely related to human brain function, suggesting additional insights concerning the anatomical and functional development of the human brain. Recently, early sulcal folding patterns have been observed in healthy fetuses and fetuses with brain abnormalities such as polymicrogyria and agenesis of corpus callosum. Graph-based quantitative sulcal pattern analysis has shown high sensitivity in detecting emerging subtle abnormalities in cerebral cortical growth in early fetal stages that are difficult to detect via qualitative visual assessment or using traditional cortical measures such as gyrification index and curvature. It has proven effective for characterizing genetically influenced early cortical folding development. Future studies will be aimed at better understanding a comprehensive map of spatio-temporal dynamics of fetal cortical folding in a large longitudinal cohort in order to examine individual clinical fetal MRIs and predict postnatal neurodevelopmental outcomes from early fetal life. PMID- 29601956 TI - The impact of financial crisis on coronary artery disease burden in Greece. AB - BACKGROUND: Economic crisis poses an immense threat to public health worldwide and has been linked to cardiovascular morbidity and mortality. Greece is facing a distinctive recession over the recent years. However, the exact impact on coronary artery disease (CAD) burden has not been adequately addressed. METHODS: Demographic, clinical, and angiographic data of 3895 hospitalized patients were retrospectively studied. Patients were classified into two groups: those before crisis (2006-2007, n = 1228) and those during crisis (2011-2015, n = 2667). RESULTS: All data before and during crisis were compared. During crisis, patients presented with less acute coronary syndrome (ACS - 45.5% vs. 39.9%, p < 0.001). Subsequently, there were more patients without CAD (23.7% vs. 35.1%, p < 0.001) or one-vessel disease (20.5% vs. 23%, p < 0.001). The prevalence of traditional risk factors decreased significantly or remained stable except obesity (26.3% vs. 31.4%, p = 0.002). A significant increase in the examined females (23.6% vs. 26.7%, p = 0.04) was also observed. CONCLUSIONS: The burden of CAD in Greece was partially affected during the financial crisis. Even though the incidence of ACS was decreased, more women and more patients with no- or single-vessel disease were referred for cardiac catheterization. In addition, the prevalence of traditional risk factors for CAD did not increase except obesity confirming the "obesity paradox." It seems that the impact of traditional risk factors for CAD is not an immediate process and is somewhat related to living conditions or other exogenous and social factors.

AB - A systematic rationalization of the hundreds of proteins harboring iron-sulfur clusters and able to exhibit the most diverse biological functions is missing. In this picture we have already reviewed structure/electrochemistry of metalloproteins expressing single types of iron-sulfur centres [namely, {Fe(Cys)4}, {[Fe2S2](Cys)4}, {[Fe2S2](Cys)3(X)} (X = Asp, Arg, His), {[Fe2S2](Cys)2(His)2}, {[Fe3S4](Cys)3}, {[Fe4S4](Cys)4} and {[Fe4S4](SgammaCys)3(nonthiolate ligand)}] and their synthetic analogs. Recently we are focussing on structure/electrochemistry of metalloproteins containing iron sulfur centres of different nuclearities. Having started such a subject with proteins harboring [4Fe-4S] and [2Fe-2S] (Zanello, 2017c) as well as [4Fe-4S] and [3Fe-4S] (Zanello, in press) clusters, we now provide the state of art of proteins harboring [4Fe-4S], [3Fe-4S] and [2Fe-2S] clusters, a subject that resulted strictly limited to enzymes active in the respiratory Complex II. PMID- 29601958 TI - Polymer-free cubosomes for simultaneous bioimaging and photodynamic action of photosensitizers in melanoma skin cancer cells. AB - We designed novel polymer-free cubic bicontinuous liquid crystalline dispersions (cubosomes) using monoolein as molecular building block, phospholipids as stabilizers, propylene glycol as hydrotrope. Their kinetic stability was evaluated by analysing the backscattering profiles upon ageing, and the most stable formulation was chosen as potential photosensitizers delivery vehicle for photodynamic therapy (PDT) of human skin melanoma cells. Morphological and topological features of such formulation alternatively loaded with Chlorin e6 or meso-Tetraphenylporphine-Mn(III) chloride photosensitizing dyes were investigated by cryo-TEM, DLS, and SAXS. Bioimaging studies demonstrated that Me45 and MeWo cell lines effectively internalized these cubosomes formulations. Particularly, photodynamic activity experiments proved both the very low cytotoxicity of the cubosomes formulation loaded with Chlorin e6 dye in the "dark" condition, and its significant cytotoxic effect after photoirradiation. The toxic effect recorded when the photosensitizer was encapsulated within the cubosomes was shown to be one order of magnitude higher than that caused by the free photosensitizer. This is the first report of biocompatible polymer-free cubosomes for potential application in both PDT and bioimaging of skin malignant melanoma. PMID- 29601959 TI - Enhanced visible-light photocatalytic activity to volatile organic compounds degradation and deactivation resistance mechanism of titania confined inside a metal-organic framework. AB - Poor visible-light-driven activity and deactivation property as well as wide band gap of the most common TiO2 photocatalyst significantly limits its practical application in volatile organic compounds (VOCs) purification. In this study, tiny TiO2 nanoparticles incorporated into a typical metal-organic framework (MOF), NH2-UiO-66, with controllable TiO2 content and size, were synthesized based on the hard-soft acid-base (HSAB) principle and applied to VOCs purification. Compared to bare TiO2, the TiO2@NH2-UiO-66 composites could extend the optical absorption to the visible light range and accelerate the photogenerated electrons-holes separation, due to the excellent interface contact between TiO2 and NH2-UiO-66. Moreover, the abundant interconnected 3D cavities of the outer MOF allowed for VOCs to easily diffuse into the pores, producing a concentration microenvironment around the encapsulated TiO2. The TiO2@NH2-UiO-66 composites exhibited a markedly improved photocatalytic efficiency and a good resistance to deactivation during the photocatalytic degradation of gaseous styrene under visible light illumination, which were associated with the synergetic effects between the TiO2 and MOF. The TiO2@NH2-UiO-66 with 5 wt% TiO2 could efficiently mineralize styrene to CO2 to some extent companying with the removal ratio >99% within 600 min, whereas the removal efficiency over the bare TiO2 only 32.5%.

AB - Herein, we report on the preparation of ultra-low sized (<100 nm in diameter) biodegradable polymeric capsules for potential applications as nanocontainers in antibiotic therapy. Hollow nanospheres based on the chitosan/poly(acrylic acid) pair are elaborated via (i) the layer-by-layer technique using gold nanoparticles (20 and 60 nm in size) as sacrificial templates, (ii) loading with amoxicillin, a betalactam antibiotic, and (iii) removal of the gold core via cyanide-assisted hydrolysis. Size, dispersity and concentration of the resulting nanocapsules are easily tuned by the nanoparticle templates, while wall thickness is controlled by the number of polyelectrolyte bilayers. Electrostatic interactions between the protonated amine groups of chitosan and the carboxyl groups of poly(acrylic acid) act as the driving attraction force allowing easy and fast design of robust and well-ordered multilayer films. Successful hydrolysis of the gold core is evidenced by time-dependent monitoring of the gold spectroscopic signature (absorbance at 519 nm and 539 nm for the gold nanoparticles with 20 and 60 nm, respectively). Crosslinked capsules are also prepared through crosslinking of the chitosan chains with glutaraldehyde. Chitosan-based nanocapsules are finally evidenced to be promising drug delivery vehicles of amoxicillin trihydrate with tuneable properties such as entrapment efficiency in the range of 62-75% and 3.5 5.5% concerning the drug loading. PMID- 29601961 TI - Self-template synthesis of nickel silicate and nickel silicate/nickel composite nanotubes and their applications in wastewater treatment. AB - Hierarchical one-dimensional (1D) hollow nanostructures have attracted intense research attention due to their unique structures that may be capable of many promising applications. Here, we report a facile and effective strategy to prepare nickel silicate nanotubes (NiSNTs). Using this approach, mesoporous SiO2 nanorods served as sacrificial templates for a simple hydrothermal process to prepare NiSNTs via a self-template route. The obtained NiSNTs preserve the tubular hierarchical morphology and hollow interior structures, which confer the NiSNTs with high surface areas and large pore volumes. These features point to NiSNTs as superior candidates for efficiently adsorbing heavy metal ions and organic dyes in wastewater. Moreover, NiSNTs can also serve as both supports and nickel sources, forming nickel silicate/nickel nanocomposite tubes (NiSNTs/Ni) via in situ reduction of NiSNTs under hydrothermal conditions. The addition of nickel precursors and surface pre-activation are therefore unnecessary. The NiSNTs/Ni exhibit efficient and recyclable catalytic properties when used for the reduction of 4-nitrophenol (4-NP). With a rational adaption, we believe this synthetic strategy can be extended to fabricate multifunctional one-dimensional hollow nanostructures with diverse compositions and morphologies, which may be useful for environmental protection, catalysis, energy and many other important domains.

AB - The applications of ionic liquids (ILs)/lamellar liquid crystals (LLCs) have great potential in nanotribology because they could be used where conventional oils could not work. To clarify the lubricating mechanism, herein, ILs/LLCs lubricants were prepared by addition of amphiphilic 1-alkyl-3-methylimidazolium hexafluorophosphate (CnmimPF6, n = 8, 12) into TritonX-100/n-C10H21OH/H2O LLCs with different concentration. The influence of alkyl chain lengths of ILs on the microstructures and the tribological properties of LLCs were investigated. The phase structure parameters and the tribological properties of the LLCs in the presence of CnmimPF6 were analyzed via freeze-fracture transmission electron microscopy (FF-TEM), the small-angle X-ray scattering (SAXS) technique, oscillating reciprocating friction and wear tester. Compared with the LLCs without CnmimPF6, 4.5 wt% CnmimPF6 /LLCs can reduce the friction and wear of sliding pairs. The better lubricating property and antiwear capability of the CnmimPF6/LLCs may be attributed to the increasing of the interlayer thickness d and the decreasing of the bilayer thickness d0 in microstructures. This work provides a better understanding of the relationship between the microstructures and friction wear performances of ILs/LLCs. PMID- 29601963 TI - Co-Ag alloy protected by nitrogen doped carbon as highly efficient and chemoselective catalysts for the hydrogenation of halogenated nitrobenzenes. AB - The design of lower-cost alternative heterogeneous catalysts for the hydrogenation of halogenated nitrobenzenes using green method to synthesize the corresponding anilines is highly desirable. In this study, Ag was incorporated into the Co-MOFs during the growing process (Co-Ag(n)-MOFs), and then followed the carbothermal reduction process without any additional procedures, we synthesized a series of Co-Ag(n)@NCs. The self-supported catalysts exhibited excellent and stable catalytic performances for the chemoselective hydrogenation of halogenated nitrobenzenes without obvious dehalogenation. The Co-Ag bimetallic alloy nanoparticles were well-dispersed and protected from aggregation and leaching by the porous nitrogen doped carbon. Besides, either hydrazine hydrate (N2H4.H2O, generating byproducts N2 and H2O) or H2 could be used as green reducing agent with excellent selectivity towards synthesizing the corresponding anilines. And when the Co/Ag content ratio was approximate 1:1, the Co-Ag(1:1)@NC showed the best catalytic performance. Moreover, the Co-Ag(1:1)@NC could be efficiently recovered by using an external magnetic force and reused without obvious decrease of catalytic activity. Thus, such highly efficient, inexpensive, stable and magnetically recyclable catalysts could show great potentials in practical applications for many important reactions. PMID- 29601965 TI - High yield production of human invariant chain CD74 constructs fused to solubility-enhancing peptides and characterization of their MIF-binding capacities. AB - The HLA class II histocompatibility antigen gamma chain, also known as HLA-DR antigen-associated invariant chain or CD74, has been shown to be involved in many biological processes amongst which antigen loading and transport of MHC class II molecules from the endoplasmic reticulum to the Golgi complex. It is also part of a receptor complex for macrophage migration inhibitory factor (MIF), and participates in inflammatory signaling. The inhibition of MIF-CD74 complex formation is regarded as a potentially attractive therapeutic target in inflammation, cancer and immune diseases. In order to be able to produce large quantities of the extracellular moiety of human CD74, which has been reported to be unstable and protease-sensitive, different constructs were made as fusions with two solubility enhancers: the well-known maltose-binding domain and Fh8, a small protein secreted by the parasite Fasciola hepatica. The fusion proteins could be purified with high yields from Escherichia coli and were demonstrated to be active in binding to MIF. Moreover, our results strongly suggest that the MIF binding site is located in the sequence between the transmembrane and the membrane-distal trimerisation domain of CD74, and comprises at least amino acids 113-125 of CD74. PMID- 29601964 TI - A systematic analysis of the expression of the anti-HIV VRC01 antibody in Pichia pastoris through signal peptide optimization. AB - Pichia pastoris (Komagataella phaffi) has been used for recombinant protein production for over 30 years with over 5000 proteins reported to date. However, yields of antibody are generally low. We have evaluated the effect of secretion signal peptides on the production of a broadly neutralizing antibody (VRC01) to increase yield. Eleven different signal peptides, including the murine IgG1 signal peptide, were combinatorially evaluated for their effect on antibody titer. Strains using different combinations of signal peptides were identified that secreted approximately 2-7 fold higher levels of VRC01 than the previous best secretor, with the highest yield of 6.50 mg L-1 in shake flask expression. Interestingly it was determined that the highest yields were achieved when the murine IgG1 signal peptide was fused to the light chain, with several different signal peptides leading to high yield when fused to the heavy chain. Finally, we have evaluated the effect of using a 2A signal peptide to create a bicistronic vector in the attempt to reduce burden and increase transformation efficiency, but found it to give reduced yields compared to using two independent vectors. PMID- 29601966 TI - Facilitation of yeast-lethal membrane protein production by detoxifying with GFP tagging. AB - Recombinant techniques for target protein production have been rapidly established and widely utilised in today's biological research. Nevertheless, methods for membrane protein production have yet to be developed, since membrane proteins generally tend to be expressed at low levels, easily aggregated, and/or even toxic to their host cells. Here we report that a GFP-tagging technique can be applied for the stable production of membrane proteins that are toxic to their host cells when overexpressed, paving the way for future advances in membrane protein biochemistry and drug development. PMID- 29601967 TI - Tarsal coalition in paediatric patients. AB - Tarsal coalition is due to failure of segmentation between two or more foot bones during embryological development at a site where the joint cleft fails to develop. Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Talo-calcaneal and calcaneo-navicular coalitions account for over 90% of all cases of tarsal coalition. The joint at the site of the coalition is stiff. Pain during physical activity is the main symptom, although recurrent ankle sprain is another possible presenting manifestation. During the physical examination, range of-motion limitation at the hindfoot or midfoot should be sought, as well as varus or valgus malalignment of the hindfoot. Either pes planus or pes cavus may be seen. Calcaneo-navicular coalition may be visible on the standard radiograph, whereas talo-calcaneal coalition is best visualised by computed tomography or magnetic resonance imaging. As growth proceeds, the coalition becomes ossified and range-of-motion diminishes. Onset of the pain is often in the second decade of life or later. In patients with symptomatic tarsal coalition, the initial management should always consist in non-operative treatment for at least 6 months. A consensus exists that surgery should be offered when non-operative treatment fails. Open resection of the coalition is the treatment of choice, although endoscopic resection is also an option. Sound evidence exists that resection of the coalition can produce favourable outcomes even in the long-term. Fusion should be reserved for failure of resection, extensive coalitions, multiple coalitions, and patients with advanced osteoarthritis. PMID- 29601968 TI - Update on leg fractures in paediatric patients. AB - Leg fractures are common and further increasing in prevalence in paediatric patients. The diagnosis is readily made in most cases. Choosing the best treatment is the main issue. Non-operative treatment is the reference standard for non-displaced or reducible and stable fractures but requires considerable expertise and close monitoring, as well as an immobilisation period that far exceeds 3 months in many cases. Some surgical teams therefore offer elastic stable intra-medullary nailing (ESIN) as an alternative to children who do not want to be immobilised for several months. Internal fixation is required for unstable or irreducible leg fractures. ESIN is often used as the first-line method, based on its very good risk/benefit ratio. For fractures that do not lend themselves to ESIN, optimal stabilisation can be achieved by choosing among the other available options (screw-plate fixation, rigid intra-medullary nailing or external fixation) on a case-by-case basis. Close monitoring during the first few days is crucial to ensure the early detection of compartment syndrome. The other complications and sequelae are non-specific. PMID- 29601969 TI - Concepts and challenges in the use of mesenchymal stem cells as a treatment for cartilage damage in the horse. AB - Osteoarthritis (OA), the most common form of joint disease affecting humans and horses, is characterized by the advance and decline of cartilage and loss of function of the affected joint. The progression of OA is steadily accompanied with biochemical events, which interfere with the cytokines and proteolytic enzymes responsible for progress of the disease. Recently, regenerative therapies have been used with an assumption that mesenchymal stem cells (MSCs) possess the potential to prevent the advancement of cartilage damage and potentially regenerate the injured tissue with an ultimate goal of preventing OA. We believe that despite various challenges, the use of allogenic versus autologous MSCs in cartilage regeneration, is a major issue which can directly or indirectly affect the other factors including, the timing of implantation, dose or cell numbers for implantation, and the source of MSCs. Current knowledge reporting some of these challenges that the clinicians might face in the treatment of cartilage damage in horses are presented. In this regard we conducted two independent studies. In the first study we compared donor matched bone marrow and synovial fluid - derived equine MSCs in vitro, and showed that the SFMSCs were similar to the BMMSCs in their proliferation, expression of CD29, CD44 and CD90, but, exhibited a significantly different chondrogenesis. Additionally, 3.2-21% of all SFMSCs were positive for MHC II, whereas, BMMSCs were negative. In the second study we observed that injection of both the autologous and allogenic SFMSCs into the tarsocrural joint resulted in elevated levels of total protein and total nucleated cell counts. Further experiments to evaluate the in vivo acute or chronic response to allogenic or autologous MSCs are imperative. PMID- 29601970 TI - Absorption of bicarbonate in sheep omasum. AB - Transport of bicarbonate across the isolated epithelium of sheep omasum was studied in vitro in Ussing chambers in combination with the pH-Stat method. The transport of HCO3- occurred in both directions, but Jms HCO3- was significant larger than Jsm. Reducing the activity of the apical Na/H exchanger by a low mucosal Na concentration caused a significant reduction of Jms HCO3-. Mucosal amiloride or short chain fatty acids (25 mmol l-1 SCFA) numerically decreased Jms HCO3-, but their combination (amiloride + SCFA) caused a significant reduction, which was also observed after addition of the carboanhydrase inhibitor ethoxyzolamide. Concentrations of 5 or 15 mmol.l-1 mucosal ammonia did not change transport rates. The obtained results indicate the importance of an undisturbed cytosolic pH for transcellular HCO3- transport, which is probably mediated by an anion exchanger in both the apical and basolateral membranes. Possible impairment of HCO3- transport appears to be an overlooked factor in the pathogenesis of displacement of the abomasum. PMID- 29601971 TI - A novel stellerite-based photocatalytic composite and its enhanced disinfection application. AB - The aim of this work was to prepare, characterize and evaluate the potential of novel ZnO/stellerite composite photocatalysts against Staphylococcus aureus (S. aureus). SEM/EDS studies employed to study the surface morphological properties revealed stellerite as the catalysts carrier played a role of dispersant for ZnO nanoparticles. The XRD patterns of the ZnO/stellerite indicated hexagonal crystal structure with 20-30 nm size. It was found that the crystallite size of ZnO/stellerite was much smaller as compared to pure ZnO and increased with increasing ZnO loading amount. The results of optical properties of ZnO/stellerite showed smaller band gap in contrast to pure ZnO, investigated by UV-vis absorption. Due to the optimum ZnO loading, the as-prepared ZnO-20 composite had the highest BET surface area and the pore volume. Using the TG-DSC measurement, the high thermal stability of the product was studied for different temperature values. Antibacterial activity of ZnO/stellerite affected by the ZnO loading, concentration of samples and light conditions (under dark and UV irradiation conditions) was examined by disinfection of S. aureus. The as prepared ZnO-20 composite with 100 mg/L was found to exhibit excellent inactivation efficiencies (87.65% in the dark and 97.67% under UV illumination) towards S. aureus. Compared with pure ZnO, the obtained composite photocatalysts showed significantly better antibacterial performance by studying the disinfection kinetics of S. aureus. Thus, the present study reveals that the novel ZnO/stellerite shows great potential for its use in the targeted disinfection applications. PMID- 29601972 TI - Complexation of Chol-DsiRNA in place of Chol-siRNA greatly increases the duration of mRNA suppression by polyplexes of PLL(30)-PEG(5K) in primary murine syngeneic breast tumors after i.v. administration. AB - RNA interference has tremendous potential for cancer therapy but is limited by the insufficient potency of RNAi molecules after i.v. administration. We previously found that complexation with PLL(30)-PEG(5K) greatly increases the potency of 3'-cholesterol-modified siRNA [Chol-siRNA] in primary murine syngeneic 4T1 breast tumors after i.v. administration but mRNA suppression decreases 24 h after the final dose. We hypothesized that complexation of cholesterol-modified Dicer-substrate siRNA (Chol-DsiRNA) in place of Chol-siRNA can increase the potency and duration of suppression by polyplexes of PLL(30)-PEG(5K) in solid tumors. We found that replacing Chol-siRNA with Chol-DsiRNA increased polyplex loading and nuclease protection, suppressed stably expressed luciferase to the same extent in primary murine 4T1-Luc breast tumors under the current dosage regimen, but maintained suppression ~72 h after the final dose. The kinetics of suppression in 4T1-Luc over 72 h, however, were similar between DsiLuc and siLuc after electroporation and between polyplexes of Chol-DsiLuc and Chol-siLuc after transfection, suggesting that Chol-DsiRNA polyplexes increase the duration of mRNA suppression through differences in polyplex activities in vivo. Thus, replacing Chol-siRNA with Chol-DsiRNA may significantly increase the duration of mRNA suppression by polyplexes of PLL(30)-PEG(5K) and possibly other PEGylated polycationic polymers in primary tumors and metastases after i.v. administration. PMID- 29601973 TI - Evaluation of a new dispersion technique for assessing triboelectric charging of powders. AB - In a number of applications, especially in pharmaceutical drug development, there is often a very small powder quantity available for evaluating the manufacturability of new drugs. However, it is highly desirable to be able to quickly evaluate processing issues, and where possible using the smallest powder quantity. In the present work, a proprietary commercial powder dispersion device (the disperser of Malvern(c) Morphologi G3) is adapted to evaluate the triboelectric charging tendency. A very small powder quantity (as small as 0.1 mg) is dispersed by a pressure pulse of compressed gas such as air or nitrogen. This causes the particles to become air borne and collide with the containing walls, resulting in dispersion and leading to triboelectric charge transfer between the particles and the walls. In this work, the charging propensity of a number of materials is evaluated and the effect of particle surface functional groups on the tribo-electric charge transfer is analysed. Model materials with a well-defined shape (glass ballotini) but with different silane groups deposited on their surfaces as well as a number of organic crystalline particles (such as aspirin, alpha-lactose monohydrate and paracetamol) are tested. Following dispersion the particles move immediately to a Faraday cup placed directly underneath the disperser. Therefore, particle charge is measured with no decay. The method can differentiate charging of different polymorphs of the same material, different silane groups on the surfaces of glass ballotini and different crystal morphologies obtained from crystallisation from various solvents. PMID- 29601974 TI - Preparation of sustained release capsules by electrostatic dry powder coating, using traditional dip coating as reference. AB - Lately, a great deal of attention is being paid to capsule coating, since the coat protects active pharmaceutical ingredients (APIs) from damage, as is in the case of tablet and pellet. However, moisture and heat sensitivity of gelatin shells make it challenging to coat capsules using the conventional aqueous coating techniques. In an effort to overcome this challenge, the present study aims to coat capsules using two different coating techniques: electrostatic dry powder coating (EDPC) and dip coating (DC). Both capsule coatings and free films were prepared by these two coating techniques, and the effects of coating formulations and processing conditions on the film quality were investigated. The corresponding drug in vitro release and mechanisms were characterized and compared. The results of dissolution tests demonstrated that the drug release behavior of both EDPC and DC coated capsules could be optimized to a sustained release of 24 h, following the Fick's diffusion law. The results of this study suggest that EDPC method is better than DC method for coating capsules, with respect to the higher production efficiency and better stability, indicating that this dry coating technology has promised in gelatin capsule coating applications. PMID- 29601975 TI - Application of a simple desolvation method to increase the formation yield, physical stability and hydrophobic drug encapsulation capacity of chitosan-based nanoparticles. AB - As one of the classical nano drug carriers, chitosan-based nanoparticles (CsNps) are getting increasing attentions for their non-toxicity, biocompatibility and biodegradability. The ionotropic gelation is the most favorable method for CsNps preparation, while it's beset by some issues, i.e. low particle formation yield, poor physical stability and low hydrophobic drug loading capacity. To solve these problems, a simple desolvation method was attempted in this study for CsNps preparation. Using this method, an increased formation yield of CsNps (about 100%) could be obtained, and after diluting the particles by various buffers (PBS 7.0, 7.4 and 8.0, DMEM medium and 1640 medium), an improved stability in diameter could be observed. The drug loading results showed paclitaxel loading efficiency of 9.8% could be obtained when the ratio of paclitaxel to Cs was set at 0.2, higher than the ionotropic gelation method (0.43%). The particles formation mechanisms were studied by the molecular dynamics simulation, and the results showed the Lennard-Jones interaction of Cs-Cs, which could be adjusted by the pH value of system, played a great role in formation of particles with the desolvation method. This study provided an alternative preparation technology for CsNps with high process yield, physical stability and hydrophobic drug encapsulation capacity.

AB - Prolactin regulatory element-binding (PREB) protein is a transcription factor that regulates prolactin (PRL) gene expression. PRL, also known as luteotropic hormone or luteotropin, is well known for its role in producing milk. However, the role of PREB, in terms of hepatic glucose metabolism, is not well elucidated. Here, we observed expression of Preb in the mouse liver, in connection with glucose homeostasis. Morevoer, Preb was downregulated in db/db, ob/ob and high fat diet-induced obese (DIO) mice, concurrent with upregulation of the liver genes glucose-6-phosphatase (G6pc) and phosphoenolpyruvate carboxykinase-1 (Pck). Administration of adenovirus-Preb (Ad-Preb) to db/db, ob/ob, and DIO mice diminished glucose, insulin, and pyruvate tolerance, which analogously, were impaired in normal (C57BL/6) mice knocked down for Preb, via infection with Ad shPreb (anti-Preb RNA), indicating Preb to be a negative regulator of liver gluconeogenic genes. We further demonstrate that Preb negatively influences gluconeogenic gene expression, by directly binding to their promoters at a prolactin core-binding element (PCBE). A better understanding of Preb gene expression, during the pathogenesis of hepatic insulin resistance, could ultimately provide new avenues for therapies for metabolic syndrome, obesity, and type-2 diabetes mellitus, disorders whose worldwide incidences are increasing drastically. PMID- 29601977 TI - SURF1 knockout cloned pigs: Early onset of a severe lethal phenotype. AB - Leigh syndrome (LS) associated with cytochrome c oxidase (COX) deficiency is an early onset, fatal mitochondrial encephalopathy, leading to multiple neurological failure and eventually death, usually in the first decade of life. Mutations in SURF1, a nuclear gene encoding a mitochondrial protein involved in COX assembly, are among the most common causes of LS. LSSURF1 patients display severe, isolated COX deficiency in all tissues, including cultured fibroblasts and skeletal muscle. Recombinant, constitutive SURF1-/- mice show diffuse COX deficiency, but fail to recapitulate the severity of the human clinical phenotype. Pigs are an attractive alternative model for human diseases, because of their size, as well as metabolic, physiological and genetic similarity to humans. Here, we determined the complete sequence of the swine SURF1 gene, disrupted it in pig primary fibroblast cell lines using both TALENs and CRISPR/Cas9 genome editing systems, before finally generating SURF1-/- and SURF1-/+ pigs by Somatic Cell Nuclear Transfer (SCNT). SURF1-/- pigs were characterized by failure to thrive, muscle weakness and highly reduced life span with elevated perinatal mortality, compared to heterozygous SURF1-/+ and wild type littermates. Surprisingly, no obvious COX deficiency was detected in SURF1-/- tissues, although histochemical analysis revealed the presence of COX deficiency in jejunum villi and total mRNA sequencing (RNAseq) showed that several COX subunit-encoding genes were significantly down-regulated in SURF1-/- skeletal muscles. In addition, neuropathological findings, indicated a delay in central nervous system development of newborn SURF1-/- piglets. Our results suggest a broader role of sSURF1 in mitochondrial bioenergetics. PMID- 29601979 TI - Ethnobotanical study of medicinal plants used by indigenous people in and around Dirre Sheikh Hussein heritage site of South-eastern Ethiopia. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The uses of medicinal plants have a long history and become important sources of the health cares in Ethiopia. These medicinal plants and their associated indigenous knowledge are being seriously depleted due to rapid change in environment and socioeconomic conditions of the country. However, as to the knowledge of the present researchers, limited studies have been done to identify these medicinal plants and to preserve the communities' indigenous knowledge on these plants. THE AIM OF THE STUDY: This study aimed at assessing and documenting traditional medicinal plant species, mode of preparation and delivery, and parts used in and around Dirre Sheikh Hussein heritage site of South-eastern Ethiopia. The study was also meant to explore related indigenous knowledge of the communities on the utilization of medicinal plants. MATERIAL AND METHODS: The data were collected using household survey, in depth interviews of key informants, focus group discussion and field observation. The number of informants involved in the survey was 194 (one hundred ninety four). RESULTS: A total of 87 medicinal plants belonging to 77 genera and 51 families were identified. These medicinal plants were comprised of shrubs (33%), trees (31%), herbs (29%) and climbers (7%). Of the total number of medicinal plants found out in the study, 43 were used to treat human diseases, 8 were used to cure animal diseases and 36 were used to treat both human and live stock ailments. Of the identified plant species, about 83% species were proved that they are commonly known and used elsewhere whereas, the uses of remainder ones are limited to the study area. Most of the medicinal plants (60%) were sourced from the forest and the rest were found from both the forest garden. The study also revealed that leaves were the most frequently mentioned (36%) plant part used in preparing remedies. Crushing (20%) and oral route of administration (59%) were commonly mentioned mode of preparation and administration, respectively The study also indicated that peoples' perception and cultural beliefs had significant influence on their preference of source of health care, whereas religion was found to have no association with the health seeking behavior. CONCLUSIONS: This study revealed that varieties of plant species are playing important role for treating different human and livestock diseases in the study area, and traditional healers have accumulated wealth indigenous knowledge on usage of plant medicine inherited through generation. Besides, the therapeutic use of the documented plants will provide basic data for further research that focus on pharmacological studies and the conservation of the most important medicinal plants. PMID- 29601980 TI - Pharmacological effect of prohibited combination pair Panax ginseng and Veratrum nigrum on colorectal metastasis in vitro and in vivo. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The pharmacological effect derived from herb-herb interaction is important to constitute the prescription especially in traditional oriental medicine. The relationship of two medicinal herbs is called "couplet medicinals" which is used in pair for the purpose of enhancing the therapeutic effect, reducing the toxic effect or the adverse effect. The "Eighteen Incompatible Medicaments" constitute one of the contents in the incompatibility of traditional oriental drugs in a prescription. Among the "Eighteen Incompatible Medicaments", the roots and rhizomes of Veratrum nigrum (VN), is incompatible with the roots and rhizomes of Panax ginseng (PG). However, definite evidences of adverse effect by these combinations has yet to be reported. MATERIALS AND METHODS: The aim of the present study was to investigate the effects of ethanol extracts of PG, VN, and their combination (P + V) on the metastatic ability of colorectal cancer (CRC) cells using WST assay, flow cytometry, western blot analysis, real-time RT-PCR, immunofluorescence, migration assay, invasion assay, zymography, and an in vivo experiment with a lung-metastasis mouse model. RESULTS: The PG extract decreased cell proliferation by inducing cell cycle arrest and apoptosis of CRC cells. In addition, PG inhibited metastatic abilities of CRC cells including Epithelial-Mesenchymal Transition, migration, and invasion. Additionally, the PG extract suppressed lung metastasis of the CRC cells in the mouse model. However, the P + V extract exhibited weaker anti proliferative and anti-metastatic effects than PG alone. CONCLUSION: Based on these results, the P + V couplet medicinal attenuates the anti-metastatic effects of PG, both in vitro and in vivo. PMID- 29601981 TI - The role of oxytocin in implicit personal space regulation: An fMRI study. AB - Personal space, defined as the distance individuals choose to maintain between themselves and others, is an indicator of affiliation and closeness. Most paradigms that measure personal space preferences involve explicit choice and therefore fail to examine the implicit aspects of such preferences. In the current study, we sought to investigate an implicit form of interpersonal space that is more closely related to real-life situations involving affiliation. We studied the effects of oxytocin (OT) on neural networks that involve affiliation and tested the impact on personal space preferences. In a double-blind placebo controlled study, we asked participants to choose between two rooms that differed only in the distances between two stimuli. The stimuli were either social stimuli (two chairs) or non-social stimuli (table and plant). The behavioral results showed that OT caused participants to choose a closer space in social blocks but did not affect their choices in non-social blocks. Imaging results revealed an interaction between stimulus and treatment (OT/PL) in the dorsal striatum, an area that is related to approach motivation and is part of the reward circuitry. Specifically, OT increased activity in the dorsal striatum in the social blocks and decreased this activity in the non-social blocks. The results of the study strengthen the social salience theory regarding OT, indicating that OT does not uniformly affect all social responses and that context has a determining impact on our behavior. PMID- 29601982 TI - Quantitation of peptides from non-invasive skin tapings using isotope dilution and tandem mass spectrometry. AB - Previous work from our laboratories utilized a novel skin taping method and mass spectrometry-based proteomics to discover clinical biomarkers of skin conditions; these included atopic dermatitis, Staphylococcus aureus colonization, and eczema herpeticum. While suitable for discovery purposes, semi-quantitative proteomics is generally time-consuming and expensive. Furthermore, depending on the method used, discovery-based proteomics can result in high variation and inadequate sensitivity to detect low abundant peptides. Therefore, we strove to develop a rapid, sensitive, and reproducible method to quantitate disease-related proteins from skin tapings. We utilized isotopically-labeled peptides and tandem mass spectrometry to obtain absolute quantitation values on 14 peptides from 7 proteins; these proteins had shown previous importance in skin disease. The method demonstrated good reproducibility, dynamic range, and linearity (R2 > 0.993) when n = 3 standards were analyzed across 0.05-2.5 pmol. The method was used to determine if differences exist between skin proteins in a small group of atopic versus non-atopic individuals (n = 12). While only minimal differences were found, peptides were detected in all samples and exhibited good correlation between peptides for 5 of the 7 proteins (R2 = 0.71-0.98). This method can be applied to larger cohorts to further establish the relationships of these proteins to skin disease. PMID- 29601983 TI - Corneal lymphangiogenesis facilitates ocular surface inflammation and cell trafficking in dry eye disease. AB - PURPOSE: While the normal cornea has limited innervation by the lymphatic system, chronic immune-inflammatory disorders such as dry eye (DE) can induce lymphangiogenesis in the ocular surface. Using a conditional knock-down murine model, Lyve-1Cre;VEGFR2flox mice, this study investigated the role of lymphangiogenesis in the pathophysiology of DE. METHODS: DE was induced in both wild type (WT) B6 and Lyve-1Cre;VEGFR2flox mice. Tissue immunostaining and volumetric gross measurements were used to assess changes in the ocular surface, skin, and lymph nodes (LNs). The expression of lymphangiogenic factors (TNF alpha, IL-6/-8/-12/-17, VEGF-C/-D, IFN-gamma, VEGFR-2/-3, Lyve-1, and podoplanin) and the frequency of immune cells (CD4, CD11b, and CD207) on the ocular surface and lacrimal glands were quantified by real-time polymerase chain reaction and flow cytometry. RESULTS: Compared to WT mice, there were fewer lymphatic vessels and a reduction in lymphangiogenic markers in the ocular surface and skin of Lyve 1Cre;VEGFR2flox mice. After DE induction, mRNA levels of TNF-alpha, IL-8, and IFN gamma were significantly reduced in Lyve-1Cre;VEGFR2flox mice compared to WT mice (p < .01). Surprisingly, the LNs from Lyve-1Cre;VEGFR2flox mice with DE were significantly smaller and populated by fewer dendritic cells and effector T cells than those from WT mice (p < .001). Furthermore, immunostaining showed corneal nerves in the DE-induced Lyve-1Cre;VEGFR2flox mice were notably intact like in the naive condition. CONCLUSIONS: Inhibition of lymphangiogenesis in the cornea effectively attenuates not only the inflammatory response including trafficking of immune cells but also preserves corneal nerves under desiccating stress. Corneal lymphangiogenesis might be a contributing factor in deterioration on the ocular surface homeostasis.

AB - Present investigation reveals copper induced phytotoxicity, oxidative stress and DNA damage in Cassia angustifolia Vahl and its amelioration by employing a symbiotic fungus, Piriformospora indica. Seeds were germinated on Knop's medium containing five Cu levels (0, 1, 10, 50, 100 and 200 mg L-1), with and without P. indica. Colonization with P. indica significantly (P < 0.05) ameliorated Cu induced oxidative stress. However, maximum amelioration was observed at 50 mg L-1 Cu with P. indica. Atomic absorption spectroscopy revealed that P. indica colonization significantly inhibited Cu accumulation in shoots. Maximum decline in Cu accumulation in shoots was observed at 50 mg L-1 (27.27%) with P. indica over Cu alone. Besides, P. indica colonized seedlings stored 16.86% higher Cu in roots as compared to Cu alone at 200 mg L-1. Similarly, maximum proline accumulation increased up to 19.32% over Cu alone at 50 mg L-1 Cu with P. indica. Significant elevation in antioxidant enzyme levels of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase and glutathione reductase was seen with P. indica. Contrary to increase in antioxidant level, toxic parameters such as lipid peroxidation and hydrogen peroxide decreased significantly with P. indica. Maximum decline in lipid peroxidation (13.76%) and hydrogen peroxide (18.58%) was observed at 50 mg L-1 with P. indica over Cu alone. P. indica significantly reduced DNA damage as well as changed the protein profile in C. angustifolia seedlings. Thus, P. indica proved to be an excellent system to alleviate Cu induced oxidative stress and might be useful as a phytostabilization tool.

AB - Cell transplantation in bioengineered scaffolds and encapsulation systems has shown great promise in regenerative medicine. Depending on the site of implantation, type of cells and their expected function, these systems are designed to provide cells with a physiological-like environment while providing mechanical support and promoting long-term viability and function of the graft. A minimally invasive 3D printed system termed neovascularized implantable cell homing and encapsulation (NICHE) was developed in polylactic acid for subcutaneous transplantation of endocrine cells, including pancreatic islets. The suitability of the NICHE for long term in vivo deployment is investigated by assessing mechanical behavior of both fresh devices under simulated subcutaneous conditions and NICHE retrieved from subcutaneous implantation in pigs. Both experimental and numerical studies were performed with a focus on validating the constitutive material model used in the numerical analysis for accuracy and reliability. Notably, homogeneous isotropic constitutive material model calibrated by means of uniaxial testing well suited experimental results. The results highlight the long term durability for in vivo applications and the potential applicability of the model to predict the mechanical behavior of similar devices in various physiological settings. PMID- 29601986 TI - A study of the reproducibility and reliability of the musculo-articular stiffness of the ankle joint. AB - The objective of this work was to evaluate the reproducibility, reliability and usefulness of the musculo-articular stiffness (MAS) of the ankle joint, measuring it by the free vibration technique. Seventeen (nine males and eight females) healthy university students were included in the study. Force (f), MAS (k) and unitary MAS (ku) (defined as the ratio between the value of stiffness k obtained in the test (absolute terms) and the value of force (f)) were obtained. A test retest protocol was designed and performed on the same day to determine the short term reproducibility of f, k and ku. Short-term reproducibility of k and ku on 1 day in absolute terms (< 7% Coefficient of Variation (CV)) and relative reproducibility (Intraclass Correlation Coefficient (ICC) and Pearson >= 0.97) for both feet were obtained. The reliability of k and ku in absolute terms (< 9% CV) and in relative terms (ICC and Pearson >=0.93) based on repeating the protocol for 1 week was analysed for both feet. To analyse the usefulness, the Effect Size (ES) ratio = "Trivial" for all variables (for 1 day and 1 week) and the Smallest Worthwhile Change (SWC) ratio (Typical Error (TE)< SWC) = "GOOD" for k and ku (1 day and 1 week) were considered. The Minimal Difference needed to be considered "real" (MD) for ku ? 3.5% (1 day); ku? 8.5% (1 week) (p < 0.05) was obtained. The statistical analysis carried out displayed the high reproducibility, reliability and usefulness of the MAS test, which was more consistent with ku than k. Therefore, the unitary stiffness (ku) proven to be representative of the mechanical response of the ankle joint obtained by free vibration techniques, which allows comparison between different subjects.

AB - Orthopaedic devices using unidirectional carbon fibre reinforced poly-ether-ether ketone (PEEK) laminates potentially offer several benefits over metallic implants including: anisotropic material properties; radiolucency and strength to weight ratio. However, despite FDA clearance of PEEK-OPTIMATM Ultra-Reinforced, no investigation of the mechanical properties or failure mechanisms of a medical grade unidirectional laminate material has been published to date, thus hindering the development of first-generation laminated orthopaedic devices. This study presents the first investigation of the mechanical behaviour and failure mechanisms of PEEK-OPTIMATM Ultra-Reinforced. The following multi-axial suite of experimental tests are presented: 0 degrees and 90 degrees tension and compression, in-plane shear, mode I and mode II fracture toughness, compression of +/-45 degrees laminates and flexure of 0 degrees , 90 degrees and +/-45 degrees laminates. Three damage mechanisms are uncovered: (1) inter-laminar delamination, (2) intra-laminar cracking and (3) anisotropic plasticity. A computational damage and failure model that incorporates all three damage mechanisms is developed. The model accurately predicts the complex multi-mode failure mechanisms observed experimentally. The ability of a model to predict diverse damage mechanisms under multiple loading directions conditions is critical for the safe design of fibre reinforced laminated orthopaedic devices subjected to complex physiological loading conditions. PMID- 29601988 TI - Oxide ceramic femoral heads contribute to the oxidation of polyethylene liners in artificial hip joints. AB - Experimental evidence demonstrates that a loss of stoichiometry at the surface of oxide bioceramic femoral heads enhances the oxidation rate of polyethylene acetabular liners in artificial hip joints. Contradicting the common notion that ceramics are bioinert, three independent experiments confirmed substantial chemical interactions between the ceramic femoral heads and their polyethylene counterparts. The experiments reported herein included hydrothermal tests, frictional tests, and hip-simulator experiments. It was discovered that oxide and non-oxide femoral heads differently affected the oxidation processes at the surface of the polyethylene liners, all other testing parameters being equal. Analytical data from X-ray photoelectron (XPS), cathodoluminescence (CL), Fourier transform infrared (FTIR), and Raman spectroscopies unequivocally and consistently showed that the oxidation rate of polyethylene liners was greater when coupled with oxide as opposed to non-oxide ceramic heads. XPS analyses of O Al-O bond fractions at the surface of a zirconia-toughened alumina (ZTA) short term (20 months in vivo) femoral heads retrieval showed a ~50% reduction in favor of oxygen vacancy O-Al-VO and hydroxylated Al-O-H bonds. Off-stoichiometry drifts were confirmed in vitro under both static and dynamic conditions. They triggered oxidation and tangibly affected an advanced highly cross-linked sequentially irradiated and annealed ultra-high molecular weight polyethylene (UHMWPE) liner (increase in oxidation index up to DeltaOI~1.2 after 5 * 105 cycles under dynamic swing conditions). Second-generation UHMWPE liners infused with vitamin E were also affected by the free flow of oxygen from the oxide femoral heads, although to a lesser extent. The fundamental findings of this study, which were also confirmed on retrievals, call for revised standards in material design and testing. Adopting these new criteria will provide an improved understanding of the importance of off-stoichiometry at the head/liner interface and may lead to significant extensions in artificial joint lifetimes. PMID- 29601989 TI - A hybrid model based on neural networks for biomedical relation extraction. AB - Biomedical relation extraction can automatically extract high-quality biomedical relations from biomedical texts, which is a vital step for the mining of biomedical knowledge hidden in the literature. Recurrent neural networks (RNNs) and convolutional neural networks (CNNs) are two major neural network models for biomedical relation extraction. Neural network-based methods for biomedical relation extraction typically focus on the sentence sequence and employ RNNs or CNNs to learn the latent features from sentence sequences separately. However, RNNs and CNNs have their own advantages for biomedical relation extraction. Combining RNNs and CNNs may improve biomedical relation extraction. In this paper, we present a hybrid model for the extraction of biomedical relations that combines RNNs and CNNs. First, the shortest dependency path (SDP) is generated based on the dependency graph of the candidate sentence. To make full use of the SDP, we divide the SDP into a dependency word sequence and a relation sequence. Then, RNNs and CNNs are employed to automatically learn the features from the sentence sequence and the dependency sequences, respectively. Finally, the output features of the RNNs and CNNs are combined to detect and extract biomedical relations. We evaluate our hybrid model using five public (protein-protein interaction) PPI corpora and a (drug-drug interaction) DDI corpus. The experimental results suggest that the advantages of RNNs and CNNs in biomedical relation extraction are complementary. Combining RNNs and CNNs can effectively boost biomedical relation extraction performance.

AB - We herein report the design and synthesis of benzothiazinones containing a piperidine moiety as new antitubercular agents based on the structure feature of IMB-ZR-1 discovered in our lab. Some of them were found to have good in vitro activity (MIC < 1 MUg/mL) against drug-susceptible Mycobacterium tuberculosis H37RV strain. After two set of modifications, compound 2i were found to display comparable in vitro anti-TB activity (MIC < 0.016 MUg/mL) to PBTZ169 against drug sensitive and resistant mycobacterium tuberculosis strains. Compound 2i also showed acceptable PK profiles. Studies to determine PK profiles in lung and in vivo efficacy of 2i are currently under way. PMID- 29601991 TI - Discovery of novel quinazolinone derivatives as high potent and selective PI3Kdelta and PI3Kdelta/gamma inhibitors. AB - PI3Kdelta and PI3Kgamma regulate immune cell signaling. Selective PI3Kdelta or PI3Kgamma inhibitors and dual PI3Kdelta/gamma inhibitors have the potential for the treatment of immune cell-mediated diseases and hematological malignancies. Based on the quinazolinone pharmacophore, we used a pyrazolo[3,4-d]pyrimidin-4 amine portion as the hinge region binding moiety, an aromatic or a heteroaromatic substituent at the 3-position of the pyrazolo[3,4-d]pyrimidine core as the affinity element, and designed novel 2-tolyl and 2,6-dimethylphenyl quinazolinone derivatives as potential PI3Kdelta inhibitors. Most of these compounds displayed high inhibitory rates (89-97%) against PI3Kdelta at the concentration of 1 MUM, with the IC50 values of 8.4 nM-106 nM. Among the 3-(2,6 dimethylphenyl)quinazolinone series, the introduction of an indol-5-yl substituent at the pyrazolo[3,4-d]pyrimidine 3-position led to a potent and selective PI3Kdelta (IC50 = 8.6 nM) inhibitor 10d, that was more than 3630-fold, 390-fold and 40-fold selective for PI3Kdelta over PI3Kalpha, beta and gamma, while the substitution with a 3,4-dimethoxyphenyl resulted in a potent and selective dual PI3Kdelta/gamma inhibitor 10e with IC50 values of 8.4 nM and 62 nM against PI3Kdelta and PI3Kgamma, respectively. Compound 10e was also more than 1400-fold, 820-fold selective for PI3Kdelta over PI3Kalpha and PI3Kbeta. In agreement with their remarkable PI3Kdelta inhibitory activity, compounds 10d and 10e showed high antiproliferative activity against human B-cell SU-DHL-6 cells. Moreover, the dual PI3Kdelta/gamma inhibitor 10e had reasonable pharmacokinetic profiles with a good plasma exposure, low clearance, low volume distribution, and an acceptable oral bioavailability of 34.9%. PMID- 29601992 TI - Cloning and functional characterization of thioredoxin genes from large yellow croaker Larimichthys crocea. AB - Thioredoxin(Trx)with a redox-active disulfide/dithiol in the active site, is an ubiquitous disulfide reductase majorly responsible for maintaining the balance of reactive oxygen species. In this study, the complete thioredoxin-like protein 1 (designated as LcTrx) was cloned from large yellow croaker Larimichthys crocea through rapid amplification of cDNA ends. The full-length cDNA of LcTrx was 1295 bp in length containing a 131 bp 5' untranslated region (UTR) ,a 3'UTR of 294bp with a poly (A) tail, and an 870 bp open reading frame (ORF) encoding a polypeptide of 289 amino acids. Protein sequence analysis revealed that LcTrx contains the evolutionarily conserved redox motif CRPC (Cys-Arg-Pro-Cys-). Multiple alignments revealed that LcTrx is highly identical to Trx from other organisms, especially in the CRPC motifs. The recombinant LcTrx showed obvious insulin reduction activity in vitro. The LcTrx transcripts were constitutively expressed in all examined tissues with the highest levels found in the muscles and the lowest in the head kidney. Results of Vibrio parahaemolyticus infection experiment showed that the expression levels of LcTrx were tissue and time dependent. In the liver and kidney, LcTrx was down-regulated both at 12 h and 48 h post-infection. In contrast, LcTrx showed induced expression in the spleen and head kidney at same post-infection time points. The different responses to pathogen stimulation indicated the diversified physiological function of LcTrx in the four examined tissues. PMID- 29601993 TI - Antimicrobial activity of a serine proteinase inhibitor SPIPm5 from the black tiger shrimp Penaeus monodon. AB - A two-domain Kazal-type serine proteinase inhibitor, SPIPm5, from Penaeus monodon was studied. Its transcript was expressed in all tissues tested including the hemocytes, stomach, gill, lymphoid organ, muscle, intestine and heart albeit less in hepatopancreas and eyestalk. The expression of SPIPm5 gene was also up regulated by heat stress, white spot syndrome virus (WSSV) infection and yellow head virus (YHV) infection. Injection of recombinant rSPIPm5 protein into normal shrimp to mimic heat stress condition did not have or had little stimulating effect on the expression of other immune genes: crustinPm1, penaeidin3, penaeidin5, Hsp70, SPIPm2 and SPIPm5. Like some other proteinase inhibitors, the rSPIPm5 could inhibit the hemolymph proPO activity. In survival experiments, the rSPIPm5 could prolong the life of WSSV-infected shrimp similar to the effect of heat stress. The rSPIPm5 also helped the YHV-, Vibrio harveyi- and V. parahaemolyticus-infected shrimp survive longer. The increased endurance against microbial infection was due to the inhibitory effects presumably activated by rSPIPm5 on viral replication and bacterial growth but not the expression of antimicrobial peptides. Therefore, the SPIPm5 plays an important role in shrimp innate immunity against the viral and bacterial infection. PMID- 29601994 TI - C-terminal domain of WSSV VP37 is responsible for shrimp haemocytes binding which can be inhibited by sulfated galactan. AB - Viral envelope proteins play an important role in facilitating the attachment of viruses to the surface of host cells. Here, we investigated the binding of White Spot Syndrome Virus (WSSV) VP37 to haemocytes of whiteleg shrimp, Litopenaeus vannamei. Three versions of recombinant VP37 proteins, including full length VP37 (VP37(1-281)), C-terminal domain VP37 (VP37(111-281)) and C-terminal domain disrupted VP37 (VP37(1-250)) were individually expressed and tested for their haemocytes binding ability. Through an ELISA-based binding assay, we found that VP37(111-281) bound to shrimp haemocytes in a similar way to VP37(1-281), while VP37(1-250) exhibited a significantly weaker binding. This suggests that the C terminal domain of VP37 is required for the binding of VP37 to shrimp haemocytes. Furthermore, we found that the binding of VP37 to shrimp haemocytes was impaired by pre-incubation of VP37 with sulfated galactan (SG), a sulfated polysaccharide derived from red seaweed (Gracilaria fisheri). Previously, it has been shown that a type of sulfated polysaccharide, heparin, is also present in L. vannamei. To investigate the role of heparin as a receptor for VP37, the binding of VP37 to porcine heparin, whose structure is similar to that found in L.vannamei, was investigated in a Surface Plasmon Resonance (SPR) system. The results showed that VP37 bound strongly to heparin with binding affinity (KD) of 1.0 MUM and the binding was significantly blocked by SG. These findings have lead us to propose that the attachment of WSSV might be mediated by the interaction between VP37 and a heparin-like molecule presented on the shrimp cells. PMID- 29601995 TI - Effect of chromium on granule-based anammox processes. AB - In this study, the feasibility of application of anaerobic ammonium oxidation (anammox) to teat wastewater containing chromium was assessed. Anammox granule activity decreased with increasing Cr(VI) concentration and pre-exposure time in batch tests, and the 50% inhibition concentration of Cr(VI) on anammox biomass was 296.5 mg L-1. Approximately 93.9% chromium was absorbed by loosely bound extracellular polymeric substances and tightly bound-extracellular polymeric substances when less than 60 mg L-1 Cr(VI) was added. During long-term operation in up-flow anaerobic sludge blanket reactor, significant inhibitory effects anammox performance were observed for Cr(VI) concentrations up to 2 mg L-1. The nitrogen removal rate (NRR) rapidly decreased to 1.49 +/- 0.89 kg N m-3 d-1, whereas the NRR was 11.37 +/- 1.30 kg N m-3 d-1 in a control reactor. Compared with initial levels, specific anammox granule activity was 22%. The tolerance of the anammox process to Cr(VI) can be enhanced after a long-term adaptive phase. PMID- 29601996 TI - Vancomycin and daptomycin minimum inhibitory concentrations as a predictor of outcome of methicillin-resistant Staphylococcus aureus bacteraemia. AB - OBJECTIVES: The aim of this study was to determine the persistence of the adverse prognostic effect of elevated vancomycin minimum inhibitory concentration (MIC) in methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia in a setting with low vancomycin use. METHODS: A retrospective study focusing on episodes of bacteraemia due to MRSA diagnosed from January 2010 through December 2015 was designed. The main outcome measures were 30-day mortality and treatment failure. Multivariate logistic regression analysis was used to identify variables associated with patient mortality and treatment outcome. RESULTS: In total, 79 MRSA bacteraemia episodes were included. The vancomycin MIC was >1.0MUg/mL in 53 episodes (67.1%). The presence of high vancomycin MIC was not associated with a higher mortality rate or treatment success. A daptomycin MIC>=0.5MUg/mL was present in 16 (26.2%) of 61 episodes for which the daptomycin MIC was obtained and was associated with 30-day mortality in the multivariate analysis (odds ratio=4.72, 95% confidence interval 1.19-18.71). None of the antimicrobials used were associated with a lower risk of treatment failure or mortality. CONCLUSIONS: The pernicious effect of high vancomycin MIC disappears in the absence of a predominant use of this antibiotic. However, a high daptomycin MIC in MRSA bacteraemia is associated with higher mortality in patients with bacteraemia, irrespective of antimicrobial treatment choice. PMID- 29601997 TI - Effectiveness of a carbohydrate restricted diet to treat non-alcoholic fatty liver disease in adolescents with obesity: Trial design and methodology. AB - BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder among children in the developed world and can progress to cirrhosis, hepatocellular carcinoma, and liver failure. No evidence-based dietary guidelines exist on the most effective diet prescription to treat NAFLD. OBJECTIVE: To compare the effect of a carbohydrate (CHO)-restricted diet vs fat-restricted diet, the current standard of care, on changes in hepatic fat infiltration, body composition, and metabolic health over an 8-week period among overweight and obese children diagnosed with NAFLD. METHODS: In this two-arm, parallel design randomized controlled trial (RCT), 40 participants aged 9 to 18 years were randomized to a CHO restricted diet (<25:>50:25% daily calories from CHO: fat: protein) or control, fat restricted diet (55,20:25% daily calories from CHO: fat: protein). This family-based diet intervention included: (1) a 2-week supply of groceries to feed a four-person household specific to the assigned diet; and (2) extensive education on diet implementation through biweekly, diet-specific group and individualized counseling sessions with participants and one parent or guardian led by a registered dietitian (RD). The primary outcome measure of this study was hepatic lipid, measured using magnetic resonance spectroscopy (MRS). Secondary outcomes included liver transaminases; markers of inflammation (hsCRP, IL-6, TNF-alpha); body composition; visceral adipose tissue; and insulin resistance. All testing was conducted at baseline and week 8; hepatic transaminases were also measured at weeks 2 and 4. This RCT is registered with ClinicalTrials.gov (ID: NCT02787668).

Auxological parameters in children and changes in body composition in adults, as well as metabolic parameters and patient related outcomes are used as clinical and surrogate endpoints. New treatment options, such as long acting GH and GH antagonists, require reevaluation of the currently used biochemical biomarkers.

AB - The last step of laparoscopic hysterectomy when the surgeon attempts to remove the uterus and close the vaginal cuff (colpotomy and cuff closure) is considered the most challenging part of the operation, and the procedure involves a steep learning curve for surgeons. Although various methods have been described and reviewed on vaginal cuff closure in laparoscopic hysterectomy, this study is the first to describe placing a single continuous running purse-string suture using the uterine manipulator to maintain a safe distance between adjacent structures while facilitating the closure before colpotomy. PMID- 29602002 TI - Hysteroscopic Intact Removal of an Angular Pregnancy with a 5Fr Electrode. AB - STUDY OBJECTIVE: Angular pregnancy is a rare and life-threatening condition in which the embryo is implanted in the lateral angle of the uterine cavity, medial to the uterotubal junction and round ligament. Angular pregnancy is associated with a high risk of uterine rupture of about 23% [1]. No consensus has been achieved regarding the diagnostic and therapeutic approach of angular pregnancy [2]. Thus, the aim of this study was to report a case of hysteroscopic treatment of an angular pregnancy in a 34-year-old women. DESIGN: Step-by-step video presentation of the surgical treatment (Canadian Task Force classification III). SETTING: Department of Neuroscience, Reproductive Sciences and Dentistry, School of Medicine, University of Naples Federico II, Naples, Italy. PATIENT: A 34-year old woman. Written informed consent was obtained from the patient. INTERVENTION: Hysteroscopy. MEASUREMENTS AND MAIN RESULTS: A 34-year-old woman was admitted to our Department with pelvic pain at 6 weeks of gestation. beta-Human chorionic gonadotropin (beta-hCG) was 5331 mIU/mL. The transvaginal ultrasound showed a gestational sac of 15 * 11 mm in the left uterine angle of an embryo without cardiac activity. The woman opted for a conservative approach with multiple-dose methotrexate [3]. Five days later the beta-hCG increased to 7589 mIU/mL with no regression of pregnancy at the transvaginal ultrasound. Therefore, a surgical approach was offered to the patient [4,5]. Laparoscopy showed normal salpinges, whereas hysteroscopy identified the gestational sac in the left uterine angle. A 5Fr bipolar electrode was used to open the gestational capsular decidua. The chorionic villi were progressively separated from the implantation site. Using grasping forceps we removed the specimen for histologic examination. Histologic examination confirmed the diagnosis of angular pregnancy. On the second postoperative day beta-hCG was 1131 mIU/mL, and the patient was discharged the day after. At the 1-month follow-up visit, beta-hCG and transvaginal ultrasound were negative for pregnancy. The office hysteroscopy showed an empty uterine cavity at 3-months' follow-up. CONCLUSION: Our case shows that hysteroscopy may be used as a diagnostic and therapeutic tool for angular pregnancy, providing a unique image of the intact removal of the gestational sac. PMID- 29602003 TI - Deep Brain Stimulation Surgery for Status Dystonicus: A Single-Center Experience and Literature Review. AB - BACKGROUND: Status dystonicus (SD) is a life-threatening complication in which episodes of dystonic movements become increasingly frequent and severe, requiring urgent hospital admission, and can lead to respiratory, metabolic, and bulbar complications. Pharmacologic treatment has been the mainstay management for this complication; however, many refractory patients will still require further treatment. Deep brain stimulation (DBS) is an established therapeutic strategy that has been used for dystonia, and now it has been proposed to be used for SD. METHODS: In this case series, we describe our experience with early DBS placement in 5 patients with SD to control symptoms that are refractory to pharmacologic therapy. In addition, we present a literature review of this therapy in the treatment of SD. RESULTS: Before discharge, symptomatic relief (decrease of dystonic movements and resolution of abnormal postures) was evidenced in all patients with a median of 3 days (interquartile range, 1-7) after surgery was performed. A follow-up Unified Dystonia Rating Scale score and Burke-Fahn-Marsden rating scale motor subscale score, at 6 months after hospital discharge with values being inferior to 20 and 30, respectively, for all cases. None of the patients had a recurrence of SD in the last follow-up period. CONCLUSIONS: DBS surgery is a suitable, versatile, reversible and adequate therapy in the treatment of SD that is refractory to initial pharmacologic treatment. PMID- 29602004 TI - Shape of the Spinal Canal Is Not Associated with Success Rates of Microsurgical Unilateral Laminotomy and Bilateral Decompression for Lumbar Spinal Canal Stenosis. AB - BACKGROUND: Anatomic shape of the spinal canal (oval, round, trefoil) has been reported to predict outcome of bilateral decompression performed in an undercutting technique via unilateral laminotomy in monosegmental lumbar spinal stenosis, with poorest results observed in a trefoil spinal canal, leading to the proposal of using bilateral instead of unilateral laminotomy. The aim of this study was to assess whether this anatomic classification into oval, round, and trefoil shapes is relevant to surgical treatment of lumbar spinal stenosis. METHODS: Retrospective chart review of patients undergoing lumbar decompression surgery was performed. Spinal canal configuration was assessed on preoperative computed tomography based on maximal transverse and anteroposterior diameter, and shapes were classified into oval, round, and trefoil. Associations between spinal canal shape and outcome improvement (aggregate of walking distance and leg pain) were tested. RESULTS: Decompression of 236 lumbar levels was performed in 159 patients (mean age, 73 +/- 8 years; mean body mass index, 29 +/- 6). Average number of operated segments was 1.3 +/- 0.6. Oval configurations were detected in 155 (65%) levels, round configurations were detected in 11 (5%) levels, and trefoil configurations were detected in 70 (30%) levels. Postoperative improvement was recorded in 91.7% of patients. Spinal canal shape had no influence on surgical outcome (oval, area under the curve 0.529, P = 0.672; trefoil, area under the curve 0.500, P = 0.997; round, area under the curve 0.471, P = 0.670). CONCLUSIONS: Spinal canal configuration varies in frequency with lumbar segment. Our results do not support the idea that this anatomic classification, particularly the nomenclature of oval, round, and trefoil, should influence surgical decision making. PMID- 29602005 TI - Transventricular Transvelar Approach to Trochlear Nerve Schwannoma: Novel Technique to Lesions of Inferior Pineal Region. AB - OBJECTIVES: The schwannoma of the trochlear nerve is rare and originates mostly from the distal parts in the interpeduncular cistern. A lesion on the proximal segment in the inferior pineal region is extremely rare. Because of the rarity of the disease, the surgical approach to this region for the resection of trochlear nerve schwannoma has not been well documented in the literature. We herein describe a novel approach to successfully resect the trochlear nerve schwannoma. METHODS: A 12-year-old boy presented with occipital headache, abnormal gait, and disturbed conjoined eye movement. He was diagnosed with a lesion in the inferior pineal region compressing the superior medullary velum into the roof of the fourth ventricle. A bilateral midline suboccipital craniotomy was performed, and the fourth ventricle was exposed. The lesion was approached through the fourth ventricle superior medullary velum (transventricular transvelar approach). The lesion was totally resected, and his histopathology examination revealed trochlear schwannoma. RESULTS: The patient's symptoms resolved, and he had no recurrence at 12-year follow-up with normal eye movement and vision. CONCLUSION: The transventricular transvelar approach is feasible and safe to treat a lesion of the lower part of the pineal region being pushed through the superior medullary velum. PMID- 29602006 TI - Microsurgical Clipping of Basilar Apex Aneurysms: A Systematic Historical Review of Approaches and their Results. AB - OBJECTIVE: Neck clipping remains a valuable treatment option for basilar apex aneurysms, especially in those with complex morphology, such as incorporation of branching vessels or large size, and young patient age. Several approaches have proved to give effective exposure for various types of lesion morphologies. Our historic literature review from 1976 to the present systematically compares the outcomes and complications of the key surgical approaches in the treatment of basilar apex aneurysms. METHODS: We searched PubMed for articles with at least 5 patients, data on neurologic outcome, and procedure-associated complications for the following approaches: pterional or orbitozygomatic transsylvian, subtemporal (with or without zygomatic osteotomy), pretemporal (with or without transcavernous extension), and transpetrous. n-Weighted averages for clinical outcome, aneurysm occlusion rates, morbidity, mortality, and aneurysm morphology were compared. RESULTS: Of 35 articles selected, 2041 patients with 722 ruptured aneurysms underwent microsurgery, including 1131 transsylvian, 241 pretemporal, 375 subtemporal, and 17 transpetrous approaches. Comparing these 4 approaches in n-weighted averages, respectively, we noted good neurologic outcomes (81%, 85%, 81%, and 58%), surgical morbidity (14%, 10%, 34%, and 53%), surgical mortality (4%, 1%, 0, and 1%), and complete occlusion rates (95%, 94%, 86%, and 75%). CONCLUSIONS: Transsylvian, pretemporal, and subtemporal approaches showed favorable neurologic outcomes at similar rates and were applied for aneurysms located between -1mm and +7mm in relation to the posterior clinoid process. The pretemporal approach was preferably applied to large and giant aneurysms with good outcome; the transsylvian approach was most frequently used for ruptured aneurysms. PMID- 29602007 TI - Successful Kissing Balloon Expandable Stent Graft Treatment for a Right Common Carotid Pseudoaneurysm Caused by Tracheotomy. AB - BACKGROUND: A rare complication following tracheotomy is common carotid artery (CCA) pseudoaneurysm. Treatment modalities for CCA pseudoaneurysm include surgical repair and single-artery balloon-covered stent graft technique. We describe successful treatment of tracheotomy-related CCA pseudoaneurysm with the "kissing balloon" expandable stent graft technique. CASE DESCRIPTION: We successfully implemented the kissing balloon expandable stent graft technique for treatment of a large, narrow-necked, bilobed CCA pseudoaneurysm that arose owing to a tracheotomy complication. The pseudoaneurysm was detected while performing a diagnostic angiogram of the aortic arch and surrounding vessels. The stent was deployed while the 2 balloons were introduced in a kissing manner such that they faced one another to avoid occlusion of either branch of the innominate artery coming into contact; 1 balloon was inflated at the origin of the right subclavian artery, and the other was inflated at the right innominate artery simultaneously. The pseudoaneurysm was successfully contained; normal blood flow was restored in the CCA. The balloons were deflated and withdrawn. The patient remained neurologically intact after the procedure. CONCLUSIONS: The kissing balloon technique is a safe and effective alternative to surgical repair, as it prevents morbidities associated with the surgical procedure. Also, this technique decreases the risk of major side-branch occlusion associated with the single artery balloon-covered stent graft technique. PMID- 29602008 TI - Complications of Full-Endoscopic Versus Microendoscopic Foraminotomy for Cervical Radiculopathy: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Minimally invasive surgery of posterior cervical foraminotomy (PCF) for symptomatic radiculopathy has gained popularity in the last decade. It remains to be determined whether the 2 dominant operation techniques, full endoscopic (FE) or microendoscopic (MI), are associated with fewer complications. METHODS: An electronic retrieval from PubMed, Embase, and Web of Science was performed to identify comparative or single-arm studies concerning FE-PCF and MI PCF. The pooled incidence of complications was calculated. RESULTS: A total of 26 studies with 2028 patients (FE, 402; MI, 1626) were identified. The overall complication rate was 5.8% for FE-PCF and 3.5% for MI-PCF, with no significant difference (P = 0.115). The pooled complication rate for single-level radiculopathy showed no statistical difference (FE, 4.5%; MI, 3.5%; P = 0.471), either. However, constituent of complications showed apparent disparity, with transient root palsy in FE-PCF (15/19, 78.9%) and dural tear (20/47, 42.6%) in MI PCF being the most commonly reported. As for the subgroup analysis, both incidence of dural tear (FE, 1.5%; MI, 1.8%; P = 0.672) and superficial wound infection (FE, 2.2%; MI, 1.0%; P = 0.109) showed no statistical difference. Nevertheless, transient root palsy occurred at a higher incidence in the FE group than in the MI group (FE, 4.5%; MI, 1.5%; P = 0.002). CONCLUSIONS: Both FE-PCF and MI-PCF can offer relatively safe treatment for cervical radiculopathy. There is no significant difference in overall complication rate between the 2 techniques. Dural tear is the most commonly reported complication of MI-PCF, whereas transient root palsy deserves to be noticed for surgeons performing FE PCF. PMID- 29602009 TI - Endovascular Recanalization of Occluded Dural Sinus in Patient with Dural Arteriovenous Fistulas: Case Report and Literature Review. AB - BACKGROUND: Symptomatic sinus occlusion complicated with dural arteriovenous fistulas (dAVFs) can be treated successfully endovascularly. However, no studies have reported the use of endovascular transvenous approaches alone to recanalize the occluded sinuses for treatment of the involved dAVFs without stent deployment. In this study, we presented a 75-year-old man with occlusion of the transverse and sigmoid sinuses complicated with a dAVF. CASE DESCRIPTION: This patient initially suffered intermittent headache, nausea, and vomiting but developed seizures and hemiplegic paralysis 2 months later. Neurologic examination revealed mildly decreased motor function in grade IV in the left limb. Intracranial pressure by lumbar puncture was 300 mm H2O. Magnetic resonance imaging venography disclosed sinus occlusion and dAVFs accounting for encephaledema. Cerebral angiography revealed occlusion of the left transverse and sigmoid sinuses and cortical reflux with the sinus junction unobstructed. The feeding arteries of the left transverse sinus dAVFs were muscular branches of the left vertebral artery and external carotid artery, and the draining vein was from the superior sagittal sinus to the contralateral transverse sinus. Balloon angioplasty plus mechanical cracking (pulling a microcatheter back and forth) was used to recanalize the occluded sinuses. The symptoms disappeared after endovascular recanalization of the occluded left transverse sinus and sigmoid sinuses, and follow-up venography revealed opened sinuses with complete disappearance of the dAVF. CONCLUSION: Endovascular transvenous recanalization may be a better alternative therapy for selected patients with dural arteriovenous fistulas complicated by sinus occlusion without stent deployment. PMID- 29602010 TI - Zirconia-Polyurethane Aneurysm Clip. AB - OBJECTIVE: Susceptibility artifacts from metal clips in magnetic resonance (MR) imaging present an obstacle to evaluating the status of clipped aneurysms, parent arteries, and adjacent brain parenchyma. We aimed to develop MR-compatible aneurysm clips. METHODS: Considering the mechanical and biologic properties, as well as MR compatibility of candidate materials, a prototype clip with a zirconia body and a polyurethane head spring (zirconia clip [ZC], straight, 9-mm long) was developed. The closing forces, opening width of blades, and in vitro and in vivo artifact volumes in 3 tesla MR imaging were compared among the prototype and commercial metal clips such as a Yasargil clip (YC, curved type, 8.3-mm long) and a Sugita clip (SC, straight type, 10-mm long). An in vivo animal study was performed with a canine venous pouch aneurysm model. RESULTS: The closing forces (N) at 1 mm and 8 mm from the blade tip were 2.09 and 3.77 in YC, 1.85 and 3.04 in SC, and 2.05 and 4.60 in ZC. The maximum opening widths (mm) was 6.8, 9.0, and 3.0 in YC, SC, and ZC, respectively. The in vitro artifact volumes of YC, SC, and ZC in time-of-flight MR imaging were 26.9, 29.7, and 1.9 times larger than the respective real volumes. The in vivo artifact volumes of YC, SC, and ZC were respectively 21.4, 29.4, and 2.6 times larger than real ones. CONCLUSIONS: ZC showed the smallest susceptibility artifacts and satisfactory closing forces. However, the narrow opening width of the blades was a weak point. PMID- 29602011 TI - TransArterial ChemoEmbolization (TACE) with platinum versus anthracyclines for hepatocellular carcinoma: A meta-analysis. AB - OBJECTIVE: To determine the clinical efficacy of TACE with platinum versus anthracyclines for hepatocellular carcinoma (HCC) patients using a meta-analysis. METHODS: We conducted a systematic review of the literature in PubMed, Embase, and the Cochrane Library database to discover relevant randomized controlled trials (RCTs) and observational studies. Data on therapeutic response, adverse event and overall survival rate from studies that compared TACE with platinum versus anthracyclines for HCC patients was extracted for pooled estimation. Subgroup analysis was used if further investigation was needed. The Q statistic and the I2 index statistic were used to assess heterogeneity. Publication bias was evaluated using Egger's test. RESULTS: Four RCTs and seven observational studies containing 1405 patients were included in this meta-analysis. After comparing RCTs and observational studies separately, the pooled estimation results indicated that no significant difference existed between platinum and anthracyclines regarding therapeutic response, adverse event and overall survival rate. Furthermore, Egger's test revealed bias in pooled estimation of survival rate among RCTs. CONCLUSIONS: Based on current results, we concluded that TACE with platinum revealed similar clinical efficacy compared with anthracyclines. And more relative studies in this field were expected in the future. PMID- 29602012 TI - Distal versus total gastrectomy for middle and lower-third gastric cancer: A systematic review and meta-analysis. AB - BACKGROUND: The optimal resection extent for middle or lower-third gastric cancer still remains controversial. This study was aim to compare the safety and long term prognosis of distal gastrectomy (DG) with total gastrectomy (TG) for middle and lower-third gastric cancer. METHODS: Pubmed, EMBASE, the Cochrane Library, and Web of Science were searched from inception to October 2017 for comparative studies comparing DG with TG for middle or lower-third gastric cancer. We performed the meta-analysis using RevMan 5.3 software. RESULTS: Overall, 11 comparative studies with 3554 patients, including 4 randomized controlled trials and 7 retrospective cohort studies, were analyzed. Compared with DG, TG showed a higher rate of overall postoperative complication, anastomosis leakage, wound complication, peritoneal abscess, and mortality. There were no significant differences between the two groups in rate of recurrence and cancer-related death. The 5-year overall survival is better in the DG group than in the TG group, but no significant differences were found in stage-specific analysis. CONCLUSIONS: Compared with TG, DG is an optimal surgical procedure for middle or lower-third gastric cancer in early and locally advanced stages with better short term outcomes and comparable long-term prognosis under the precondition of negative proximal resection margin. PMID- 29602013 TI - DNA methylation as an epigenetic regulator of gallbladder cancer: An overview. AB - Gallbladder cancer (GBC) is a lethal health issue affecting mostly the women in their middle-age. High incidence of GBC has been reported across the world specifically in Asian countries, India and Pakistan. The exact etiology remains unknown, although several risk factors and genetic aberrations involving mutations or epigenetic changes may be involved in gallbladder carcinogenesis. This article presents a review of the published literature mainly from the year 2003 onwards. The topic of main concerns was epigenetic regulation of GBC. All relevant studies identified were included and are described according to the aforementioned subheadings. In this review, we have discussed the role of DNA methylation in GBC, clinical implication and future prospects of biomarker development for early diagnosis and therapeutic interventions. PMID- 29602014 TI - The clinicopathological and prognostic value of Nanog in human gastrointestinal luminal cancer: A meta-analysis. AB - BACKGROUND: Recent studies have demonstrated that the over-expression of Nanog contributes to the progression of various malignant tumors. However, the clinicopathological and prognostic role of Nanog in gastrointestinal luminal cancer remains controversial. Therefore, we conducted a meta-analysis to assess the role of Nanog in gastrointestinal luminal cancer. METHODS: An electronic search for relevant literature was performed in PubMed, Cochrane Library, Web of Science, and EMBASE databases. The relationships between Nanog expression and clinicopathological features and survival outcomes were analyzed. Pooled odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated by STATA14.2 and RevMan 5.3 software. RESULTS: A total of 9 studies with 1526 patients were included in this meta-analysis. The positive expression of Nanog was related to gender, depth of infiltration, differentiation, and TNM stage; however, it was not associated with age, tumor size, or lymph node metastasis. Moreover, positive Nanog expression was correlated with a poor overall survival (OS) and poor disease-free survival (DFS) in gastrointestinal luminal cancer. CONCLUSION: The pooled results suggested that Nanog expression was associated with gender, depth of infiltration, differentiation, and TNM stage, and Nanog may be a potential biomarker to predict the prognosis of gastrointestinal luminal cancer. PMID- 29602015 TI - Geriatric Nutritional Risk Index as a prognostic factor in patients with esophageal squamous cell carcinoma -retrospective cohort study. AB - PURPOSE: The Geriatric Nutritional Risk Index (GNRI) is a new index recently introduced to predict the risk of nutrition-related complications and mortality. Our aim is to examine the association between the GNRI and long-term prognosis in patients with esophageal squamous cell carcinoma (ESCC) who underwent esophagectomy. METHODS: The present study enrolled consecutive 216 patients with ESCC who underwent esophagectomy. The GNRI at admission to the hospital was calculated as follows: (1.489 * albumin, g/l) + (41.7 * present/ideal body weight). The characteristics and long-term prognosis were compared between four groups: the severe risk (GNRI: <82), moderate risk (GNRI: 82 to <92), low risk (GNRI: 92 to <98) and no risk (GNRI: >98) groups. The 5-year overall survival and independent prognostic factors were investigated, respectively. RESULTS: A decreased GNRI significantly correlated with unfavorable overall survival (p < 0.001). In all patients, a multivariate analysis demonstrated that the severe and moderate risk groups (GNRI: <92) (hazard ratio 0.50; p = 0.002), T factor (>=T2) (hazard ratio 0.52; p = 0.026), and N positive factor (hazard ratio 0.47; p = 0.004) were independent prognostic factors. In the subgroup analysis, which excluded patients with preoperative chemoradiotherapy, the severe and moderate risk groups (GNRI: <92) (hazard ratio 0.48; p = 0.0057), and T factor (>=T2) (hazard ratio; p = 0.021) were independent prognostic factors. CONCLUSIONS: GNRI is considered to be a useful prognostic factor in patients with ESCC undergoing esophagectomy. PMID- 29602016 TI - Role of liver resection in treating intermediate and advanced stage adolescent and young adult hepatocellular carcinoma patients: A propensity-matching cohort study. AB - BACKGROUND: Hepatocellular carcinoma (HCC) in adolescent and younger adult (AYA) patients is usually diagnosed at an advanced stage such that curative treatments are often not possible. The aimed of this study was to compare the outcome of attempted curative treatment, liver resection (LR) versus transarterial chemoembolization (TACE), in AYA patients presenting with intermediate or advanced HCC defined by the Barcelona Clinic Liver Cancer (BCLC) stage B and C. METHODS: All AYA patients diagnosed with BCLC stage B or C HCC undertaking LR (n = 276) and TACE (n = 136) were included in our study. The prognostic factors of the patients were analyzed and the propensity score-matched patients (120 pairs) were analyzed to adjust for any baseline differences. RESULTS: The overall survival rate of the patients undertaking LR was higher than TACE for the both entire and the propensity matched population (p < 0.001). In the multivariate analysis, propensity scoring analyses suggested that HBsAg positivity, macrovascular invasion, tumor size and TACE treatment were the independent prognostic factors associated with a worse survival outcome. CONCLUSION: The effect of LR was superior to that of TACE for patients with intermediate and advanced stage HCC. The survival outcome was associated with the tumor size, macrovascular invasion, and hepatitis history in AYA HCC patients. PMID- 29602017 TI - Assessing safety and feasibility of 'pure' laparoscopic total gastrectomy for advanced gastric cancer in the West. Review article. AB - BACKGROUND: Gastric cancer is reported to be the fourth most common cancer and the second leading cause of cancer-related death worldwide. Minimally invasive surgical treatment for gastric cancer is a very challenging approach which offers undoubtedly important advantages. MATERIALS AND METHODS: There is intense debate concerning the minimally invasive surgical approach for advanced gastric cancer especially in the Western population. A careful literature search was conducted in order to clarify the feasibility and safety of pure laparoscopic total gastrectomy in the West. RESULTS: Herewith we aim to summarize the current scientific evidence assessing the feasibility and short-term outcomes of laparoscopic gastrectomy for advanced gastric cancer in the West. A lack of data from Western institutions regarding minimally invasive surgical approach for gastric cancer is yet a reality. Nevertheless, the laparoscopic procedure appears to provide satisfactory short-term oncologic outcomes and improved postoperative outcomes. CONCLUSION: It is obvious that future well-conducted trials on long term results are necessary for Western patients in order safe conclusions to be reached regarding a potential definitive 'place' for laparoscopy in the curative gastric cancer treatment. PMID- 29602018 TI - Low dose caffeine as a salivary tracer for the determination of gastric water emptying in fed and fasted state: A MRI validation study. AB - Improving our knowledge about human gastrointestinal physiology and its impact on oral drug delivery is crucial for the development of new therapies and effective drug delivery systems. The aim of this study was to develop an in vivo tool to determine gastric emptying of water by administration of a caffeine as a tracer substance followed by subsequent saliva caffeine analysis. For this purpose, 35 mg of caffeine were given to six healthy volunteers after a 10 h overnight together with 240 mL of tap water either on a fasted stomach or 30 min after the high-caloric, high-fat breakfast recommended for bioavailability/bioequivalence (BA/BE) studies. Caffeine was administered in form of an ice capsule in order to omit the contamination of the oral cavity with caffeine. Parallel to saliva sampling, magnetic resonance imaging (MRI) was applied in order to validate this novel approach. After administration of the ice capsule, MRI measurements were performed every 2 min for the first 20 min followed by further measurements after 25, 30, 35, 40, 50 and 60 min. Saliva samples were collected always 1 min after the MRI measurement in supine position in the MRI scanner and continued for further 240 min. The caffeine concentration in saliva was quantified after liquid liquid extraction by a validated HPLC/MS-MS method. The obtained MRI data revealed a fast emptying of the co-administered water within 10 to 50 min in the fasted state and likewise in the fed state. Salivary caffeine kinetics showed a Cmax from 150 to 400 ng/mL with a tmax from 20 to 90 min. MRI data were normalized by setting the maximum emptied volume to 100% and the salivary caffeine kinetics were normalized by setting Cmax to 100%. In order to compare the results obtained by the MRI and the saliva method, the normalized data for each volunteer was correlated based on a linear regression. In the fasted state the mean slope for six comparisons was 0.9114 +/- 0.1500 and the mean correlation coefficient was 0.912 +/- 0.055. In the fed state, a mean slope of 0.8326 +/- 0.1630 and a mean correlation coefficient of 0.887 +/- 0.047 were obtained. Based on these results, we could show that salivary caffeine concentrations are suitable to describe the emptying of water as a non-caloric liquid from the fasted and the fed stomach. The presented technique provides a straight-forward, inexpensive and noninvasive method to assess gastric emptying of hydrophilic liquids, which can be broadly used in oral biopharmaceutics. Possible applications are the characterization of real-life conditions, specific populations (e.g. elderly people) and the better understanding of the contribution of gastric emptying to pharmacokinetic profiles of orally administered drugs. PMID- 29602019 TI - Investigation and simulation of dissolution with concurrent degradation under healthy and hypoalbuminaemic simulated parenteral conditions- case example Amphotericin B. AB - Guidance on dissolution testing for parenteral formulations is limited and not often related in vivo performance. Critically ill patients represent a target cohort, frequently hypoalbuminaemic, to whom certain parenteral formulations are administered. Amphotericin B (AmB) is a poorly soluble, highly protein-bound drug, available as lipid-based formulations and used in critical illness. The aim of this study was to develop media representing hypoalbuminaemic and healthy plasma, and to understand and simulate the dissolution profile of AmB in biorelevant media. Dissolution media were prepared with bovine serum albumin (BSA) in Krebs-Ringer buffer, and tested in a flow through cell apparatus and a bottle/stirrer setup. Drug activity was tested against Candida albicans. BSA concentration was positively associated with solubility, degradation rate and maximum amount dissolved and negatively associated with dissolution rate constant and antifungal activity. In the bottle/stirrer setup, a biexponential model successfully described simultaneous dissolution and degradation and increased in agitation reduced the discriminatory ability of the test. The hydrodynamics provided by the flow-through cell apparatus was not adequate to dissolve the drug. Establishing discriminating test methods with albumin present in the dissolution media, representing the target population, supports future development of biorelevant and clinically relevant tests for parenteral formulations. PMID- 29602020 TI - Mimicking brain tissue binding in an in vitro model of the blood-brain barrier illustrates differences between in vitro and in vivo methods for assessing the rate of brain penetration. AB - Assessing the rate of drug delivery to the central nervous system (CNS) in vitro has been used for decades to predict whether CNS drug candidates are likely to attain their pharmacological targets, located within the brain parenchyma, at an effective dose. The predictive value of in vitro blood-brain barrier (BBB) models is therefore frequently assessed by comparing in vitro BBB permeability, usually quoted as the endothelial permeability coefficient (Pe) or apparent permeability (Papp), to their rate of BBB permeation measured in vivo, the latter being commonly assessed in rodents. In collaboration with AstraZeneca (DMPK department, Sodertalje, Sweden), the in vitro BBB permeability (Papp and Pe) of 27 marketed CNS drugs has been determined using a bovine in vitro BBB model and compared to their in vivo permeability (Pvivo), obtained by rat in-situ brain perfusion. The latter was taken from published data from Summerfield et al. (2007). This comparison confirmed previous reports, showing a strong in vitro/in vivo correlation for hydrophilic compounds, characterized by low brain tissue binding and a weak correlation for lipophilic compounds, characterized by high brain tissue binding. This observation can be explained by the influence of brain tissue binding on the uptake of drugs into the CNS in vivo and the absence of possible brain tissue binding in vitro. The use of glial cells (GC) in the in vitro BBB model to mimic brain tissue binding and the introduction of a new calculation method for in vitro BBB permeability (Pvitro) resulted in a strong correlation between the in vitro and in vivo rate of BBB permeation for the whole set of compounds. These findings might facilitate further in vitro to in vivo extrapolation for CNS drug candidates. PMID- 29602021 TI - A comparison of two biorelevant in vitro drug release methods for nanotherapeutics based on advanced physiologically-based pharmacokinetic modelling. AB - As a growing number of nanotherapeutics enters the market, improved analytical techniques for measuring the drug release are required. Biorelevant release tests have become a standard in the prediction of in vivo pharmacokinetics but also in quality control of novel dosage forms. In the present study, two methods for testing the drug release from nanocarriers, namely the filtration technique and the dispersion releaser technology, have been investigated. Initially, the in vitro release rates were determined using two different biorelevant media. Additionally, the effect of each method on a simulated in vivo pharmacokinetic profile was studied using advanced PBPK modelling. The two methods resulted in slightly different release profiles. Applying the filtration method, an early plateau of 91.0 +/- 5.3% was reached at the first sampling time point. In comparison, the release rate steadily increased to a maximum of 100.9 +/- 4.1% when the dispersion releaser technology was used. Sensitivity analysis revealed how these differences translated into the PBPK-based simulation. A change in the total dissolution rate of 10% resulted in cmax values of +1.6% and -11.0%, respectively, when using input data obtained with the dispersion releaser. Data obtained by filtration translated into cmax values of +/-1.8%. PMID- 29602022 TI - Modeling Alzheimer's disease cognitive scores using multi-task sparse group lasso. AB - Alzheimer's disease (AD) is a severe neurodegenerative disorder characterized by loss of memory and reduction in cognitive functions due to progressive degeneration of neurons and their connections, eventually leading to death. In this paper, we consider the problem of simultaneously predicting several different cognitive scores associated with categorizing subjects as normal, mild cognitive impairment (MCI), or Alzheimer's disease (AD) in a multi-task learning framework using features extracted from brain images obtained from ADNI (Alzheimer's Disease Neuroimaging Initiative). To solve the problem, we present a multi-task sparse group lasso (MT-SGL) framework, which estimates sparse features coupled across tasks, and can work with loss functions associated with any Generalized Linear Models. Through comparisons with a variety of baseline models using multiple evaluation metrics, we illustrate the promising predictive performance of MT-SGL on ADNI along with its ability to identify brain regions more likely to help the characterization Alzheimer's disease progression. PMID- 29602023 TI - "What the mind does not know, the eyes do not see". Placing food allergy risk in sub-Saharan Africa. AB - Policy makers and health geographers are increasingly intrigued by the global rise of chronic disease. While current engagement coalesce around cardiovascular disease, cancers, chronic respiratory disease, and diabetes, very little attention has been given to other important chronic conditions: e.g., allergic disease. Concerns about how health is shaped by context and experienced in place can provide important insights to understand the trajectory of allergic disease and inform policy especially in developing countries experiencing an epidemiologic transition. Using Ghana as a case study. this paper draw on theories of political ecology of health to enhance our understanding of how individual (e.g. care seeking behaviours), sociocultural (e.g. lack of education and awareness), health system (e.g. absence of logistics) and policy environments (e.g. absence of policy) influence the ways in which food allergy is perceived, diagnosed and managed. These findings highlight the need for decision makers to target structural factors that impede access to and utilization of healthcare, diagnostic practices, as well as food allergy coping and management strategies. Moreover, the findings highlight the need for a global health agenda that pays critical attention to place-based factors in the construction of emerging health risks. PMID- 29602024 TI - Colorimetric chemosensors based on diketopyrrolopyrrole for selective and reversible recognition of fluoride ions. AB - A series of colorimetric and reversible receptors for fluoride anions based on diketopyrrolopyrrole (DPP) were designed and synthesized successfully. The position of nitro substituent on the phenylhydrazide affected the alteration of photophysical properties to varying degrees. While the photoluminescence intensity of receptor 1 was weaker than that of receptor 2 and receptor 3 on account of the formation of intramolecular hydrogen bond deriving from oxygen atom of nitro substituent and hydrogen atom of hydrazide. The receptor 2 was a preferable chemosensor for responding fluoride anions. The fluorescence was quenched in the presence of fluoride anion resulted from the photo-induced electron transfer (PET) effect from the amide. The formation of deprotonation species, which produced by hydrazide NH moiety and F- was answerable for the spectral changes. Especially, the spectral and color responses of receptors could be switched back and forth successively by adding F- and HSO4- anions in DMSO solution. These receptors could response fluoride anion sensitively, visually and selectively in a manner of reversible with a low determination. PMID- 29602025 TI - Adaptive handling of Rayleigh and Raman scatter of fluorescence data based on evaluation of the degree of spectral overlap. AB - At present the general scatter handling methods are unsatisfactory when scatter and fluorescence seriously overlap in excitation emission matrix. In this study, an adaptive method for scatter handling of fluorescence data is proposed. Firstly, the Raman scatter was corrected by subtracting the baseline of deionized water which was collected in each experiment to adapt to the intensity fluctuations. Then, the degrees of spectral overlap between Rayleigh scatter and fluorescence were classified into three categories based on the distance between the spectral peaks. The corresponding algorithms, including setting to zero, fitting on single or both sides, were implemented after the evaluation of the degree of overlap for individual emission spectra. The proposed method minimized the number of fitting and interpolation processes, which reduced complexity, saved time, avoided overfitting, and most importantly assured the authenticity of data. Furthermore, the effectiveness of this procedure on the subsequent PARAFAC analysis was assessed and compared to Delaunay interpolation by conducting experiments with four typical organic chemicals and real water samples. Using this method, we conducted long-term monitoring of tap water and river water near a dyeing and printing plant. This method can be used for improving adaptability and accuracy in the scatter handling of fluorescence data. PMID- 29602026 TI - Biomethanization of citrus waste: Effect of waste characteristics and of storage on treatability and evaluation of limonene degradation. AB - This study proposes the evaluation of the suitability of mesophilic anaerobic digestion as a simple technology for the treatment of the citrus waste produced by small-medium agro-industrial enterprises involved in the transformation of Citrus fruits. Two different stocks of citrus peel waste were used (i.e., fresh and stored citrus peel waste), to evaluate the influence of waste composition (variability in the type of processed Citrus fruits) and of storage (potentially necessary to operate the anaerobic digester continuously over the whole year due to the seasonality of the production) on anaerobic degradation treatability. A thorough characterization of the two waste types has been performed, showing that the fresh one has a higher solid and organic content, and that, in spite of the similar values of oil fraction amounts, the two stocks are significantly different in the composition of essential oils (43% of limonene and 34% of linalyl acetate in the fresh citrus waste and 20% of limonene and 74% of linalyl acetate in the stored citrus waste). Contrarily to what observed in previous studies, anaerobic digestion was successful and no reactor acidification occurred. No inhibition by limonene and linalyl acetate even at the maximum applied organic load value (i.e., 2.72 gCODwaste/gVSinoculum) was observed in the treatment of the stored waste, with limonene and linalyl acetate concentrations of 104 mg/l and 385 mg/l, respectively. On the contrary, some inhibition was detected with fresh citrus peel waste when the organic load increased from 2.21 to 2.88 gCODwaste/gVSinoculum, ascribable to limonene at initial concentration higher than 150 mg/l. A good conversion into methane was observed with fresh peel waste, up to 0.33 [Formula: see text] at the highest organic load, very close to the maximum theoretical value of 0.35 [Formula: see text] , while a lower efficiency was achieved with stored peel waste, with a reduction down to 0.24 [Formula: see text] at the highest organic load. PMID- 29602027 TI - Purification of residual leach liquors from hydrometallurgical process of NiMH spent batteries through micellar enhanced ultra filtration. AB - Hydrometallurgical processes for the treatment and recovery of metals from waste electrical and electronic equipment produce wastewaters containing heavy metals. These residual solutions cannot be discharged into the sewer without an appropriate treatment. Specific wastewater treatments integrated with the hydrometallurgical processes ensure a sustainable recycling loops of the electrical wastes to maximize the metals recovery and minimize the amount of wastes and wastewaters produced. In this research activity the efficiency of ultrafiltration combined with surfactant micelles (micellar-enhanced ultrafiltration) was tested to remove metals form leach liquors obtained after leaching of NiMH spent batteries. In the micellar-enhanced ultrafiltration, a surfactant is added into the aqueous stream containing contaminants or solute above its critical micelle concentration. When the surfactant concentration exceeding this critical value, the surfactant monomers will assemble and aggregate to form micelles having diameter larger than the pore diameter of ultrafiltration membrane. Micelles containing contaminants whose diameter is larger than membrane pore size will be rejected during ultrafiltration process, leaving only water, unsolubilized contaminants and surfactant monomers in permeate stream. The experiments are carried out in a lab-scale plant, where a tubular ceramic ultrafiltration membrane is used with adding a surfactant to concentrate heavy metals in the retentate stream, producing a permeate of purified water that can be reused inside the process, thus minimizing the fresh water consumption. PMID- 29602028 TI - Monte Carlo simulations and experimental results on neutron production in the uranium spallation target QUINTA irradiated with 660 MeV protons. AB - The activation experiment was performed using the accelerated beam of Phasotron accelerator at the Joint Institute for Nuclear Research (JINR). The natural uranium spallation target QUINTA was irradiated with protons with energy 660 MeV. Monte Carlo simulations of neutron production were performed using the Geant4 code. The number of leakage neutrons from the sections of the uranium target surrounded by the lead shielding and the number of leakage neutrons from lead were determined. The total number of fissions in the setup QUINTA was determined. Experimental values of reaction rates for the produced nuclei in the 127I sample were obtained and several values of reaction rates were compared with the results of simulations. Experimentally determined fluence of neutrons in energy interval 10-175 MeV using the (n,xn) reactions in the 127I(NaI) sample was compared with the results of simulations. Possibility of transmutation of the long-lived radionuclide 129I in the QUINTA setup was estimated. PMID- 29602029 TI - Universal scaling of transverse wave attenuation in polycrystals. AB - A single mode approximation for the transverse attenuation coefficient in polycrystals is obtained from the far field approximation model (Rokhlin et al., 2015). The model is applicable in all frequency ranges to polycrystals with ellipsoidal grains of triclinic symmetry and is shown to be in favorable agreement with other second order models. In the frame of this model, the transverse wave attenuation coefficient depends on a single elastic scattering factor only (it solely encompasses dependence on the crystallite elastic moduli and the elastic covariance). Therefore in this approximation the attenuation coefficient can be scaled with this factor (normalized), obtaining the universal (master) curve. The admissibility of scaling is supported by the use of the second order model (the type of Stanke-Kino) for a large number of material systems with different grain anisotropies. Within the second order model, the behavior of the scaled transverse wave attenuation coefficient versus frequency is nearly independent of the material system and is a function of the grain geometrical characteristics only. The scaling of the transverse wave attenuation coefficient is tested on the measurements for Ti alloy samples performed in this work and a large set of experimental data obtained for different material systems available in the literature. The results confirm the scaled coefficient independence of the material and good agreement between the data and the universal attenuation curve. PMID- 29602030 TI - Children's referential communication skills: The role of cognitive abilities and adult models of speech. AB - Referential communication is effective when speakers describe a specific entity in a way that leads to accurate identification of that referent among competitors. Young children's initial referential expressions are often inadequate, and this state of miscommunication needs to be repaired in subsequent communicative attempts. Exposure to adults' effective descriptions of referents is beneficial for children to develop referentially clear initial descriptions. Here, we examined whether adult models of speech also provide benefits for children's communicative repair behavior. Furthermore, we assessed the relation between children's cognitive abilities and referential communication skills. We tested 59 children (aged 4 years to 5 years 9 months) on their ability to request specific stickers among similar distractors in a pretest-modeling-posttest design. In the modeling phase, 30 children heard more informative descriptions of stickers with relative clauses (e.g., "you selected the horse that the boy is riding") and 29 children heard less informative descriptions with demonstrative noun phrases (e.g., "you selected that horse"). In a second session, we measured children's short-term memory, executive functions (working memory and cognitive flexibility), and theory of mind. Children who heard more informative expressions showed a greater increase in uniquely identifying initial descriptions than children who heard less informative expressions. Hearing more informative expressions did not provide an additional benefit in repairing ambiguous messages, an ability we found to be related to cognitive flexibility and memory. Results indicate that informative language structures that uniquely identify referents provide limited benefits to children for effective communication where children's short-term memory and executive functions also matter. PMID- 29602031 TI - Highly sensitive microfluidic paper-based photoelectrochemical sensing platform based on reversible photo-oxidation products and morphology-preferable multi plate ZnO nanoflowers. AB - A microfluidic paper-based analytical device (MUPAD) was simply constructed for highly sensitive detection of L-glutamic acid and L-cysteine. The MUPAD featured with two functional zones on one strip of paper achieved by preferable multi plate ZnO nanoflowers (ZnO NFs) and molecularly imprinting polymer (MIP) membranes. The as-designed MUPAD was established based on the inherent relation between the photo-oxidation products and photoelectrochemical (PEC) performance with the highly sensitive detection of biomolecules. The ZnO NFs were utilized to produce photo-oxidation products by driving the reaction between ferrocenemethanol and photogenerated holes under ultraviolet light. The photo oxidation products easily flowed to MIP membranes along the hydrophilic channel via capillary action. MIP membranes as the receptors specifically recognized the analytes as well as decreased the electron loss by blocking the reduction reaction between electrons and photo-oxidation products. The PEC response was obtained in the processes of electrons transfer and exhibited the direct relationships corresponding to the concentrations of target analytes. The MUPAD showed the detection limits toward L-glutamic acid and L-cysteine as low as 9.6 pM and 24 pM, respectively. Moreover, it is interesting to point out that ZnO NFs nanostructure shows superior PEC signal compared with those of ZnO nanospheres, nanosheets, and nanorod arrays. In current work, photo-oxidation products are utilized to achieve highly sensitive PEC detection for biomolecules under ultraviolet light as well as avoid the effects of multiple modifications in the same region on the reproducibility, which is beneficial for opening up rich possibility for designing more efficient analytical strategy. PMID- 29602032 TI - Identification and characterisation of Staphylococcus aureus on low cost screen printed carbon electrodes using impedance spectroscopy. AB - Staphylococcus aureus infections are a cause of significant morbidity and mortality, in addition to representing a considerable economic burden. The aim of this study was to explore a low cost screen printed electrode as a sensor for the detection of S. aureus using impedance spectroscopy. S. aureus was incubated in chambers containing the electrodes and the results analysed using a novel normalisation approach. These results show that it is possible to detect the presence of S. aureus in LB media after 30 min incubation of a 1% growth culture, in addition to being able to see immediate cell concentration dependant changes in 0.9% NaCl. These observations imply that a number of electrochemical mechanisms cause a change in the impedance as a result of the presence of S. aureus, including adsorption to the electrode surface and the metabolism of the bacteria during growth. The study suggests that this detection approach would be useful in a number of clinical scenarios where S. aureus leads to difficult to treat infections. PMID- 29602033 TI - Molybdenum disulfide field-effect transistor biosensor for ultrasensitive detection of DNA by employing morpholino as probe. AB - This work reports on a molybdenum disulfide (MoS2) based field-effect transistor (FET) biosensor for ultrasensitive label-free detection of DNA via phosphorodiamidate morpholino oligos (PMO)-DNA hybridization. After the chip was fabricated and the sensing channel was modified with positive charges, the negatively charged MoS2 nanosheet was drop-casted onto the channel, enabling MoS2 to tightly bind to the sensing surface via electrostatic interactions. Meanwhile, DNA analogue, PMO, was immobilized on the MoS2 surface, and detection of PMO-DNA hybridization was conducted by the fabricated MoS2 FET biosensor. Due to the neutral character and high affinity of PMO, a limit of detection (LOD) down to 6 fM was obtained, which is lower than that of the previously reported MoS2 FET DNA biosensor based on DNA-DNA hybridization. In addition, the MoS2 FET biosensor also showed high sequence specificity capable of distinguishing the complementary DNA from one-base mismatched DNA, three-base mismatched DNA and noncomplementary DNA. Moreover, the unique FET biosensor was able to detect DNA in complex sample like serum, making the method potential in disease diagnostics. PMID- 29602034 TI - Automatic smartphone-based microfluidic biosensor system at the point of care. AB - Point-of-care testing technique is increasingly important for healthcare management in human being's daily life. However, traditional biosensor systems for health care are relatively expensive, bulky and hard-to-handle, which largely limits their use in point of care testing. The problems mentioned above are successfully addressed with the popularization of smartphone and the development of microfluidic technology for their applications of biosensor, which integrates smartphones, microfluidic components and sensory elements together, paving the way for wide application of smartphone-based microfluidic biomedical sensory system. According to the varieties of analytes, the most common sensing modalities of biosensor systems are divided into imaging analysis to detect cells and bacteria, biochemical analysis to detect blood sugar and blood fat, immunoassay to detect protein specifically bound to antibody, as well as molecular diagnosis to detect DNA and other biomolecules. Based on the most common analytical methods, this review article covers five types of smartphone based microfluidic biosensor systems at the point-of-care detection, i.e., smartphone-based imaging biosensor, smartphone-based biochemical sensor, smartphone-based immune biosensor, smartphone-based hybrid biosensor with more than one sensing modality, and smartphone-based molecular sensor. We lay emphasis on reviewing the structures, analytical methods and sensing modalities about the four kinds of biosensor systems with detailed discussions on their application potentials, aiming at giving the audience an overview of the recent developments of automatic smartphone-based microfluidic biosensor systems, as well as their future prospective. PMID- 29602035 TI - A flexible and highly sensitive nonenzymatic glucose sensor based on DVD-laser scribed graphene substrate. AB - Flexible and implantable glucose biosensors are emerging technologies for continuous monitoring of blood-glucose of diabetes. Developing a flexible conductive substrates with high active surface area is critical for advancing the technology. Here, we successfully fabricate a flexible and highly sensitive nonenzymatic glucose by using DVD-laser scribed graphene (LSG) as a flexible conductively substrate. Copper nanoparticles (Cu-NPs) are electrodeposited as the catalyst. The LSG/Cu-NPs sensor demonstrates excellent catalytic activity toward glucose oxidation and exhibits a linear glucose detection range from 1 MUM to 4.54 mM with high sensitivity (1.518 mA mM-1 cm-2) and low limit of detection (0.35 MUM). Moreover, the LSG/Cu-NPs sensor shows excellent reproducibility and long-term stability. It is also highly selective toward glucose oxidation under the presence of various interfering species. Excellent flexing stability is also demonstrated by the LSG/Cu-NPs sensor, which is capable of maintaining 83.9% of its initial current after being bent against a 4-mm diameter rod for 180 times. The LSG/Cu-NPs sensor shows great potential for practical application as a nonenzymatic glucose biosensor. Meanwhile, the LSG conductive substrate provides a platform for the developing next-generation flexible and potentially implantable bioelectronics and biosensors.

AB - A series of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole derivatives were designed, synthesized and evaluated for their biological activity. Most of these compounds showed potent activities against c-Met kinase and cell growth inhibition. The most promising compound, 7d, has the IC50 values of 2.02 and 88 nM to inhibit c Met kinase activity and cell growth in the MKN45 cell line, respectively. In addition, 7d is highly selective to c-Met and exhibits over 2500-fold selective inhibition to 16 tyrosine kinases evaluated. PMID- 29602037 TI - Synthesis and anti-mitotic activity of 2,4- or 2,6-disubstituted- and 2,4,6 trisubstituted-2H-pyrazolo[4,3-c]pyridines. AB - An efficient synthetic route for the synthesis of 2H-pyrazolo[4,3-c]pyridines, primarily varying by the substituents at the 2-, 4- and 6-positions, is described here. A Sonogashira-type cross-coupling reaction was employed to yield 3-alkynyl 1H-pyrazole-4-carbaldehydes, ethanones and propanones from the corresponding 1H pyrazol-3-yl trifluoromethanesulfonates. Subsequent treatment of the coupling products with dry ammonia afforded a versatile library of 2H-pyrazolo[4,3 c]pyridines, which were then evaluated for their cytotoxicity against K562 and MCF-7 cancer cell lines. The most potent of these compounds displayed low micromolar GI50 values in both cell lines. Active compounds induced dose dependent cell-cycle arrest in mitosis, as shown by flow cytometric analysis of DNA content and phosphorylation of histone H3 at serine-10. Moreover, biochemical assays revealed increased activities of caspases-3/7 in treated cells, specific fragmentation of PARP-1, and phosphorylation of Bcl-2, collectively confirming apoptosis as the mechanism of cell death. PMID- 29602038 TI - A comprehensive review of chalcone derivatives as antileishmanial agents. AB - Leishmaniasis is a group of infectious neglected tropical diseases caused by more than 20 pathogenic species of Leishmania sp. Due to the limitations of the current treatments available, chalcone moiety has been drawn with a lot of attention due to the simple chemistry and synthesis, being reported with antileishmanial activity in particular against amastigote form. This review aims to provide an overview towards antileishmanial activity of chalcones derivatives against amastigote form for Leishmania major, L. amazonensis, L. panamensis, L. donovani and L. infantum as well as their structure-activity relationship (SAR), molecular targets and in silico ADMET evaluation. In this way, it is expected that this review may support the research and development of new promising chalcones candidates a leishmanicidal drugs. PMID- 29602039 TI - Potent and selective aldo-keto reductase 1C3 (AKR1C3) inhibitors based on the benzoisoxazole moiety: application of a bioisosteric scaffold hopping approach to flufenamic acid. AB - The aldo-keto reductase 1C3 (AKR1C3) isoform plays a vital role in the biosynthesis of androgens and is considered an attractive target in prostate cancer (PCa). No AKR1C3-targeted agent has to date been approved for clinical use. Flufenamic acid and indomethacine are non-steroidal anti-inflammatory drugs known to inhibit AKR1C3 in a non-selective manner as COX off-target effects are also observed. Recently, we employed a scaffold hopping approach to design a new class of potent and selective AKR1C3 inhibitors based on a N-substituted hydroxylated triazole pharmacophore. Following a similar strategy, we designed a new series focused around an acidic hydroxybenzoisoxazole moiety, which was rationalised to mimic the benzoic acid role in the flufenamic scaffold. Through iterative rounds of drug design, synthesis and biological evaluation, several compounds were discovered to target AKR1C3 in a selective manner. The most promising compound of series (6) was found to be highly selective (up to 450 fold) for AKR1C3 over the 1C2 isoform with minimal COX1 and COX2 off-target effects. Other inhibitors were obtained modulating the best example of hydroxylated triazoles we previously presented. In cell-based assays, the most promising compounds of both series reduced the cell proliferation, prostate specific antigen (PSA) and testosterone production in AKR1C3-expressing 22RV1 prostate cancer cells and showed synergistic effect when assayed in combination with abiraterone and enzalutamide. Structure determination of AKR1C3 co crystallized with one representative compound from each of the two series clearly identified both compounds in the androstenedione binding site, hence supporting the biochemical data. PMID- 29602040 TI - Prevention and management of carcinoid crises in patients with high-risk neuroendocrine tumours undergoing peptide receptor radionuclide therapy (PRRT): Literature review and case series from two Australian tertiary medical institutions. AB - Peptide receptor radionuclide therapy (PRRT) is an important therapeutic option for somatostatin receptor (SSTR) positive metastatic and/or inoperable neuroendocrine tumours (NETs). However, in patients with poorly controlled carcinoid syndrome, it may lead to an acute flare of carcinoid symptoms or even carcinoid crisis. We report seven patients who received PRRT with (177Lu-DOTA0, Tyr3) octreotate (177Lu-octreotate-LuTate) across two Australian tertiary medical institutions who developed acute flare of carcinoid symptoms/carcinoid crisis during/after PRRT. Cases were identified as high-risk due to previous history of carcinoid crises, high tumour burden and markedly elevated tumour markers. We propose a protocol to prevent and manage severe carcinoid symptoms in high-risk patients treated with PRRT. PMID- 29602042 TI - LQTA-R: A new 3D-QSAR methodology applied to a set of DGAT1 inhibitors. AB - The rapid advances in computational methods for the drug design have resulted in the accurate predictions of biological activities of ligands with or without the availability of enzyme structures. 3D-QSAR is one of the computational methods used for such purpose. Currently, freely available 3D-QSAR methods suffer the limitations like complex methodologies, difficulty in the analysis of results, applying the statistical methods and validations of models built. Present work describes simple and novel 3D-QSAR methodology, which uses bash scripts LQTA_R_LJ, LQTA_R_QQ and LQTA_R_HB using freely available R statistical program. These scripts then generate Leenard-Jones, Coulomb and Hydrogen bond descriptors. These descriptors provide the steric 3D property, electrostatic property and hydrogen bond formation capacity respectively. These scripts have been tested for the set of DGAT1 inhibitors and results showed that the 3D-QSAR models built have better predictive abilities in terms of R2 0.735, Q2loo 0.635 and R2ext 0.715. The 3D-QSAR model suggested that the substitutions of the alkyl group at the oxadiazolyl ring at the 6th position of the pyrrolo-pyridazine ring is undesirable, on the contrary, substituted phenyl ring at 7th position is responsible for the improved DGAT1 inhibitory activity. The analysis also suggested that 6th position could be substituted with the oxadiazolyl ring or analogous heterocyclic rings, where the 3rd position of such heterocyclic rings substituted with rigid hydrophobic substitute can improve DGAT1 activity. PMID- 29602041 TI - Electrochemical immunosensor for highly sensitive and quantitative detection of tumor necrosis factor-alpha in human serum. AB - Highly sensitive and selective biosensors for accurate determination of specific protein biomarkers at low levels in serum are a prerequisite for the present healthcare systems. Therefore, here we developed a label-free impedimetric method for tumor necrosis factor-alpha (TNF-alpha) detection using reduced graphene oxide (RGO) with gold nanoparticles (AuNP) on an indium tin oxide (ITO) microdisk electrodes. The detection mechanism relies on resistance change occurs due to [Fe(CN)6]3-/4- redox probe movement towards the conductive channels of the AuNP RGO films gated by the recognition of the target biomarker by its anti-TNF-alpha antibody. The conductivity of the AuNP-RGO structures enhanced by 10-fold in comparison with bare electrode chips. The observed resistance changes at 2Hz (DeltaR at 2Hz) enabled the quantification of various concentrations of TNF-alpha in human serum (CHS-TNF-alpha). The antibody-adsorbed electrode showed a good increment of resistance change (DeltaR) with additions of antigen concentration. The sensor possesses a linear range of 1-1000pg/ml had a detection limit of 0.67pg/ml (38.51fM) and 0.78pg/ml (44.83fM) in PBS and human serum, respectively. PMID- 29602043 TI - A survey of recently emerged genome-wide computational enhancer predictor tools. AB - The race for the discovery of enhancers at a genome-wide scale has been on since the commencement of next generation sequencing decades after the discovery of the first enhancer, SV40. A few enhancer-predicting features such as chromatin feature, histone modifications and sequence feature had been implemented with varying success rates. However, to date, there is no consensus yet on the single enhancer marker that can be employed to ultimately distinguish and uncover enhancers from the enormous genomic regions. Many supervised, unsupervised and semi-supervised computational approaches had emerged to complement and facilitate experimental approaches in enhancer discovery. In this review, we placed our focus on the recently emerged enhancer predictor tools that work on general enhancer features such as sequences, chromatin states and histone modifications, eRNA and of multiple feature approach. Comparisons of their prediction methods and outcomes were done across their functionally similar counterparts. We provide some recommendations and insights for future development of more comprehensive and robust tools. PMID- 29602045 TI - Chemoenzymatic synthesis of new derivatives of glycyrrhetinic acid with antiviral activity. Molecular docking study. AB - We present an efficient approach to the synthesis of a series of glycyrrhetinic acid derivatives. Six derivatives, five of them new compounds, were obtained through chemoenzymatic reactions in very good to excellent yield. In order to find the optimal reaction conditions, the influence of various parameters such as enzyme source, nucleophile:substrate ratio, enzyme:substrate ratio, solvent and temperature was studied. The excellent results obtained by lipase catalysis made the procedure very efficient considering their advantages such as mild reaction conditions and low environmental impact. Moreover, in order to explain the reactivity of glycyrrhetinic acid and the acetylated derivative to different nucleophiles in the enzymatic reactions, molecular docking studies were carried out. In addition, one of the synthesized compounds exhibited remarkable antiviral activity against TK + and TK- strains of Herpes simplex virus type 1 (HSV-1), sensitive and resistant to acyclovir (ACV) treatment. PMID- 29602044 TI - Effects of environmentally relevant sub-chronic atrazine concentrations on African clawed frog (Xenopus laevis) survival, growth and male gonad development. AB - Sub-chronic toxicity of environmentally relevant atrazine concentrations on exposed tadpoles and adult male African clawed frogs (Xenopus laevis) was evaluated in a quality controlled laboratory for 90 days. The aim of this study was to determine the effects of atrazine on the survival, growth and gonad development of African clawed frogs. After exposure of tadpoles to atrazine concentrations of 0 (control), 0.01, 200 and 500 MUg L-1 in water, mortality rates of 0, 0, 3.3 and 70% respectively were recorded for the 90 day exposure period. Morphometry showed significantly reduced tadpole mass in the 500 MUg L-1 atrazine exposed tadpoles (p < 0.05). Light microscopy on testes of adult frogs exposed to the same atrazine concentrations using hematoxylin and eosin (H&E) and Van Gieson staining techniques revealed gonadal atrophy, disruption of germ cell lines, seminiferous tubule structure damage and formation of extensive connective tissue around seminiferous tubules of frogs exposed to 200 MUg L-1 and 500 MUg L 1 atrazine concentrations. Ultrastructural analysis of the cellular organelles using transmission electron microscopy (TEM) revealed significant amounts of damaged mitochondria in testosterone producing Leydig cells as well as Sertoli cells. Biochemical analysis revealed reduced serum testosterone levels in adult frogs at all exposure levels as well as presence of six atrazine metabolites in frog serum and liver. The results indicate that atrazine concentrations greater than the calculated LC50 of 343.7 MUg L-1 cause significant mortality in tadpoles, while concentrations >=200 MUg L-1 adversely affect reproductive health of adult frogs and development of tadpoles sub-chronically exposed to atrazine. PMID- 29602046 TI - Synthesis, anti-inflammatory screening, molecular docking, and COX-1,2/-5-LOX inhibition profile of some novel quinoline derivatives. AB - New quinoline compounds comprising pyrazole scaffold through different amide linkages were synthesized. The synthesized compounds were evaluated for their anti-inflammatory activity. Eight compounds (5c, 11b,c, 12c, 14a,b, 20a and 21a) were found to exhibit promising anti-inflammatory profiles in acute and sub-acute inflammatory models. They were screened for their ulcerogenic activity and none of them showed significant ulcerogenic activity comparable to the reference drug celecoxib and are well tolerated by experimental animals with high safety margin (ALD50 > 0.3 g/kg). Compounds 5c, 11b,c, 12c, 14a,b, 20a and 21a showed significant in vitro LOX inhibitory activity higher than that of zileuton. In vitro COX-1/COX-2 inhibition study revealed that compounds 12c, 14a,b and 20a showed higher selectivity towards COX-2 than COX-1. Among the tested compounds, 12c, 14a and 14b showed the highest inhibitory activity against COX-2 with an IC50 values of 0.1, 0.11 and 0.11 MUM respectively. The docking experiments attempted to postulate the binding mode for the most active compounds in the binding site of COX-2 enzymes and confirmed the high selectivity binding towards COX-2 enzyme over COX-1. PMID- 29602047 TI - Molecular characterization of Aspergillus fumigatus isolated from raw cow milk in Argentina: Molecular typing of A. fumigatus from raw cow milk. AB - Aspergillus fumigatus, the major etiological agent of human and animal aspergillosis, is a gliotoxinogenic species into section Fumigati commonly found in contaminated animal environments. In dairy herds, exposed areas of lactating cows, as mammalian glandule, can be easily contaminated by them. This study was aimed to identify A. fumigatus sensu lato strains (identified based on morphology) isolated from raw cow milk at species level, by morphological and molecular techniques, and to estimate their genetic variability. Forty-five A. fumigatus strains showed similar RAPD profiles (generated with PELF and URP1F primers) to each other and to A. fumigatus sensu stricto reference strains; also, they were almost identical to clinical human and feed-borne A. fumigatus strains included in the assay, since their similarity coefficient ranged from 0.7 to 1.00. Therefore, all strains were characterized as belonging to A. fumigatus sensu stricto species. This result was supported by sequencing the benA gene of selected strains and by maximum parsimony analysis. In addition, RAPD fingerprinting demonstrated intra-specific genetic variability into the A. fumigatus sensu stricto cluster. The results found in this study strengthen the fact that A. fumigatus sensu stricto is the predominant species in the Aspergillus section Fumigati found in animal environments such as dairy herd environments, while other species such as A. novofumigatus, A. fumigatiaffinis, A. udagawae and A. lentulus may be rarely isolated. Since no differences between animal and human strains were observed they can become pathogenic also for farm handlers'. Moreover, the presence of A. fumigatus sensu stricto in raw cow milk is probably a very important risk factor since milk and its by-products are generally indented for human consumption, then gliotoxin could be transferred to them.

AB - Human lymphoblast cells from a male diagnosed with Alzheimer's disease (AD) expressing the TREM2 p.R47H variant were used to generate integration-free induced pluripotent stem cells (iPSCs) by over-expressing episomal-based plasmids harbouring OCT4, SOX2, NANOG, LIN28, c-MYC and L-MYC. AD-TREM2-1 was defined as pluripotent based on (i) expression of pluripotency-associated markers (ii) embryoid body-based differentiation into cell types representative of the three germ layers and (iii) the similarity between the transcriptome of the iPSC line and the human embryonic stem cell line H1 with a Pearson correlation of 0.947. PMID- 29602049 TI - Dynamic balance control during stair negotiation for older adults and people with Parkinson disease. AB - It is well understood that stability during ambulation is reliant upon appropriate control of the trunk segment, but research shows that the rhythmicity of this segment is significantly reduced for people with Parkinson's disease (PD). Given the increased risk associated with stair ambulation, this study investigated whether people with PD demonstrate poorer trunk control during stair ambulation compared with age-matched controls. Trunk accelerations were recorded for twelve PD patients and age-matched controls during stair ascent and descent. Accelerations were used to derive measures of harmonic ratios and root mean square (RMS) acceleration to provide insight into the rhythmicity and amplitude of segmental motion. Compared with what is typically seen during level-ground walking, gait rhythmicity during stair negotiation was markedly reduced for older adults and people with PD. Furthermore, both groups exhibited significantly poorer trunk movements during stair descent compared to stair ascent, suggesting that both populations may face a greater risk of falling during this task. As stair negotiation is a common activity of daily life, the increased risk associated with this task should be considered when working with populations that have an increased risk of falling. PMID- 29602050 TI - Position of pelvis in the 3rd month of life predicts further motor development. AB - The aim of the study is to select elements of motor skills assessed at 3 months that provide the best predictive properties for motor development at 9 months. In all children a physiotherapeutic assessment of the quantitative and qualitative development at the age of 3 months was performed in the prone and supine positions, which was presented in previous papers as the quantitative and qualitative assessment sheet of motor development. The neurological examination at the age of 9 months was based on the Denver Development Screening Test II and the evaluation of reflexes, muscle tone (hypotony and hypertony), and symmetry. The particular elements of motor performance assessment were shown to have distinct predictive value for further motor development (as assessed at 9 months), and the pelvis position was the strongest predictive element. Irrespective of the symptomatic and anamnestic factors the inappropriate motor performance may already be detected in the 3rd month of life and is predictive for further motor development. The assessment of the motor performance should be performed in both supine and prone positions. The proper position of pelvis summarizes the proper positioning of the whole spine and ensures proper further motor development. To our knowledge, the presented motor development assessment sheet allows the earliest prediction of motor disturbances. PMID- 29602051 TI - Children who stutter at 3 years of age: A community-based study. AB - PURPOSE: Lack of social resources to support children who stutter may be due, in part, to the absence of epidemiological data regarding stuttering. This study investigated the proportion of three-year-old children who stutter in a city located in Hokkaido, a northern island of Japan. METHODS: The speech of individual children was assessed as part of a routine, government-conducted health care examination for 3-year-old children. The number of children screened was 2274, or 94.4% of all children in the city. The first author participated in the health care examination, and followed up all of the children who were found to stutter. RESULTS: At 3 years of age, 1.41% of the children exhibited stuttering; 82.8% of these children subsequently did not exhibit stuttering six months later. Boys were 1.57 times more likely to stutter than girls, but they had only 86% of the probability of reported or observed fluency seen in girls six months later. Significantly higher probability of later fluency was observed in children who exhibited normal, rather than delayed, language development at the 1.5-year health checkup preceding the 3-year health checkup. CONCLUSION: The proportion of three-year-old children who stutter and fluency status 6 months later are reported for a large cohort of Japanese children in Hokkaido. Language skills at 1;6 year may potentially be a factor in natural recovery or persistence; because of limitations in our study design, this assumption requires additional study. This is the first preliminary study to determine the proportion of three-year-old children who stutter in a Japanese community. PMID- 29602052 TI - Comparison of adults who stutter with and without social anxiety disorder. AB - PURPOSE: Social anxiety disorder is a debilitating anxiety disorder associated with significant life impairment. The purpose of the present study is to evaluate overall functioning for adults who stutter with and without a diagnosis of social anxiety disorder. METHOD: Participants were 275 adults who stuttered (18-80 years), including 219 males (79.6%) and 56 females (20.4%), who were enrolled to commence speech treatment for stuttering. Comparisons were made between participants diagnosed with social anxiety disorder (n = 82, 29.8%) and those without that diagnosis (n = 193, 70.2%). RESULTS: Although the socially anxious group was significantly younger than the non-socially anxious group, no other demographic differences were found. When compared to the non-socially anxious group, the socially anxious group did not demonstrate significantly higher self reported stuttering severity or percentage of syllables stuttered. Yet the socially anxious group reported more speech dissatisfaction and avoidance of speaking situations, significantly more psychological problems, and a greater negative impact of stuttering. CONCLUSION: Significant differences in speech and psychological variables between groups suggest that, despite not demonstrating more severe stuttering, socially anxious adults who stutter demonstrate more psychological difficulties and have a more negative view of their speech. The present findings suggest that the demographic status of adults who stutter is not worse for those with social anxiety disorder. These findings pertain to a clinical sample, and cannot be generalized to the wider population of adults who stutter from the general community. Further research is needed to understand the longer-term impact of social anxiety disorder for those who stutter. PMID- 29602053 TI - EEG findings and outcomes of continuous video-EEG monitoring started prior to initiation of seizure treatment in the perinatal stroke. AB - BACKGROUND: To analyze the findings in the background EEG activity of infants who suffered perinatal stroke. METHODS: Eleven neonates born 2009-2014 diagnosed of ischemic stroke by MRI (three of them with multistroke) underwent continuous video-EEG monitoring. Visual and spectral (power spectrum and coherence) analyses of the background EEG was performed in three moments: 1) Onset of EEG recording (prior to initiate seizure treatment), 2) Post-ictal epoch (1-2 h after the last seizure), and 3) one-two days after seizure control. All children aged 2-6 years underwent neurodevelopmental assessment. RESULTS: Discontinuity, asymmetry, asynchrony, transients, and relative power spectrum in delta and theta frequency bands increased significantly (p < 0.05) in the post-ictal epoch with respect to onset of EEG recording. After seizure control, discontinuity, asynchrony, and theta power spectrum no longer had significant differences with those found at onset of EEG recording. Significant differences between the ischemic and unaffected hemispheres were found in transients and in beta coherence (p = 0.002; p = 0.001, respectively) exclusively in the post-ictal epoch. Seizure burden and time-to-control ranged 5-38 min and 0.5-40 h respectively. Currently, only one child is affected by spastic monoparesis. The intelligence quotients ranged 96 123. CONCLUSIONS: The background EEG can undergo significant changes in the post ictal epoch due to the seizure activity triggered by the perinatal stroke. Most of these EEG changes involve all brain activity and not exclusively the ischemic hemisphere. Many of these modifications in the EEG background reverse following the seizure control. Video-EEG monitoring allows accurate/immediate diagnosis and rapid/intensive treatment of the stroke-associated seizures.

AB - THC, CBD, CBN, THC-COOH and 11-OH-THC are the most popular markers of cannabis consumption and abuse. The use of this drug is a serious social problem worldwide. In this study, a method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) operated in electron ionization (EI) with simple and rapid liquid-liquid extraction (LLE) and derivatization was developed and validated for the simultaneous determination of THC, CBD, CBN and 11-OH-THC in hair samples. The detection of all compounds was based on multiple reaction monitoring (MRM) transitions. The most important advantage of this method is the single-step, quick, easy and effective sample extraction procedure for THC, CBD, CBN and 11-OH-THC. The method showed a good linearity with a correlation coefficient (r2) between 0.997 and 0.999 for all substances. The variation coefficient (%CV) was <5% for THC, 11-OH-THC and CBD and <13% for CBN. The limit of detection (LOD) was 0.03 pg/mg for 11-OH-THC and it ranged from 0.3 to 1.4 pg/mg for THC, CBD and CBN. The limit of quantification was 0.1 pg/mg for 11-OH THC and it ranged from 0.9 to 4.7 pg/mg for THC, CBD and CBN. Analytical recovery was higher than 88% for 11-OH-THC and it ranged between 68 and 97% for THC, CBD and CBN. Intra- and inter-assay precision and accuracy were always lower than 9 14% and 5-9%, respectively. In parallel, we have quantified the THC-COOH level, following the methods previously set-up by us. The whole procedure was successfully applied to more than 200 different hair samples from cannabis consumers, disclosing the presence of 11-OH-THC in a range between 0.2 pg/mg and 27 pg/mg, and the presence of THC-COOH in a range between 0.05 pg/mg and 42.05 pg/mg. These data provided a good start towards the use of 11-THC-OH as alternative hair biomarker of cannabis consumption.

AB - In this work a sample treatment based on a modified QuEChERS method combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC MS/MS) was proposed to determine the residues of five common tetracyclines in fish muscle samples. The separation was achieved in less than 4 min and the analytes were detected in electrospray ionization in positive mode (ESI+) with multiple reaction monitoring mode. Parameters affecting the extraction step, such as the amount of sample and EDTA-McIlvaine buffer and extraction solvent volumes, were optimized by means of experimental design. In order to obtain the lowest matrix effect, parameters affecting the clean-up step by dispersive solid phase extraction (dSPE), were also studied. Under optimum conditions, matrix effect was lower than ?15?% in all cases. Limits of quantification were lower than 4.4 MUg kg-1 for the compounds in the selected samples, being in compliance with the current legislation. The precision, expressed as relative standard deviation, was below 18.5% and the recoveries for fortified fish samples (salmon and panga) higher than 80%. These results revealed that the proposed method is simple, rapid, cheap and environmentally friendly, being successfully applicable for the determination of these residues in fish samples. PMID- 29602056 TI - Hydrophilic interaction liquid chromatography-tandem mass spectrometry method for the determination of intact oxaliplatin in cells: validated and applied in colon cancer HCT-116 cell line. AB - Oxaliplatin is a platinum compound that is frequently prescribed for the chemotherapeutic treatment of colorectal cancer. In tumor cells, cellular uptake is the first step of oxaliplatin action. Cellular accumulation of oxaliplatin is considered to play an important role in anti-cancer efficacy. However, limited information about cellular accumulation of intact oxaliplatin is available. In this study, a sensitive hydrophilic interaction liquid chromatography-tandem mass spectrometry (HILIC-MS/MS) approach for the quantification of oxaliplatin in cells was developed and validated. The method allowed for a rapid and simple determination of intact oxaliplatin in cell lysate. The retention time of oxaliplatin was 3.04 min, which was achieved by applying a chromatographic gradient elution of 5 min. The lower limit of quantification (LLOQ) was 2 ng/mL and the analytical range of oxaliplatin was linear between 2-200 ng/mL. The intra day precision and inter-day precision (RSD (relative standard deviation)) ranged from 0.52 to 7.89%, and the accuracy (RE (relative error)) was within +/- 4.5%. Matrix effects and recovery were acceptable. The method was successfully used for the determination of intact oxaliplatin uptake by HCT-116 colon cancer cells. Thus, our findings may prospectively support a celluar pharmacokinetic study and low concentration measurement of intact oxaliplatin in the clinic.

AB - Epitaxial undoped and Gd2O3-doped ceria films were grown by pulsed laser deposition on (1 1 1) faced Y2O3-stabilized zirconia (YSZ). Highly localized cerium reduction at the film-substrate interfaces is revealed by atomically resolved valence EELS mapping using Cs aberration-corrected scanning transmission electron microscopy. The chemical profiles reveal interdiffusion of Ce, (Gd), Y, Zr, forming an intermixing zone at the interface 7-9 (1 1 1) lattice planes wide. In its vicinity, the fraction of Ce3+ raises gradually over 6-8 lattice planes from zero in the bulk ceria to ~100% in one single plane at the interface. Beyond this plane the Ce3+ fraction drops sharply within the YSZ substrate. In the vicinity of the interface systematic scan deflections are observed during EELS line scans. The advancing electron probe experiences a retarding force at the ceria side, and an accelerating force at the YSZ side, irrespective of the scan direction. This behavior is suggestive of coulombic interactions between the electron probe and a charged interface. This is interpreted as an indication of the presence of a space-charge situation at the YSZ/ceria interface, resulting from an excess negative charge at the ceria side (due to Ce3+cations) and an excess positive charge at the YSZ side (due to oxygen vacancies). PMID- 29602058 TI - Cell mechanics of pollen tube growth. AB - The pollen tube features particular traits that can only be understood when integrating cell biological with cell mechanical concepts. Firstly, regular temporal variations in the growth rate are governed by a feedback mechanism thought to involve mechanosensitive ion channels. Secondly, the tube uses invasive growth to penetrate the flower tissues with the aim to transport the male sperm cells to their target. Thirdly, the pollen tube is able to reorient its growth direction upon exposure to a guidance cue; the steering mechanism involves the sophisticated choreography of intracellular transport processes. Sophisticated imaging and micromanipulation techniques have been instrumental for the advancement in characterizing the biomechanical features of this crucial cell in the plant reproductive cycle. PMID- 29602059 TI - Evaluation of particulate 137Cs discharge from a mountainous forested catchment using reservoir sediments and sinking particles. AB - The time and size dependencies of particulate 137Cs concentrations in a reservoir were investigated to evaluate the dynamics of 137Cs pollution from a mountainous forested catchment. Sediment and sinking particle samples were collected using a vibracorer and a sediment trap at the Ogaki Dam Reservoir in Fukushima, which is located in the heavily contaminated area that formed as a result of the Fukushima Dai-ichi Nuclear Power Plant accident of 2011. The inventory of 137Cs discharged into the reservoir during the post-accident period (965 days) was estimated to be approximately 3.0 * 1012-3.9 * 1012 Bq, which is equivalent to 1.1%-1.4% of the initial estimated catchment inventory. The particulate 137Cs concentration showed a decline with time, but the exponent value between the specific surface area and the 137Cs concentration for the fine-sized (<63 MUm) particle fraction remained almost constant from the immediate aftermath of the accident. These quantitative findings obtained by reconstructing the contamination history of particulate 137Cs in reservoir sediments and sinking particles have important implications for the evaluation of 137Cs dynamics in mountainous forested catchments. PMID- 29602060 TI - Central bank interest rate decisions, household indebtedness, and psychiatric morbidity and distress: Evidence from the UK. AB - BACKGROUND: Central banks set economy-wide interest rates to meet exclusively economic objectives. There is a strong link between indebtedness and psychiatric morbidity at the individual level, with interest rates being an important factor determining ability to repay debt. However, no prior research has explored whether central bank interest rate changes directly influence mental health, nor whether this varies by levels of indebtedness. METHODS: We use British data (N = 93,255) to explore whether the Bank of England base-rate affected how perceived burden of non-mortgage debt (low, medium, and high) influenced psychiatric morbidity. Psychiatric morbidity was measured using the General Health Questionnaire (GHQ-12). Our primary outcome measure was a binary indicator of "psychiatric caseness" (>3 on a 0-12 scale). We also used the GHQ-12 as a continuous measure of distress. RESULTS: When interest rates are high (low) there is an increased (decreased) risk of psychiatric morbidity only among those with a high debt burden (b = 0.026, p = 0.02). This result was robust to alternative explanations. Thus a 1 percentage point base-rate increase is associated with a 2.6% increase that someone with a high debt burden will experience psychiatric morbidity. LIMITATIONS: Our study uses subjective indicators of debt burden. We were unable to determine the mechanism behind our effect. CONCLUSIONS: Changes in central bank interest rates to meet economic objectives pose a threat to mental health. Mental health support is needed for those in debt and central banks may need to consider how their decisions influence population mental health. PMID- 29602061 TI - Enhanced DNA mixture deconvolution of sexual offense samples using the DEPArrayTM system. AB - The interpretation of DNA mixtures remains a significant challenge in the analysis of forensic evidence. The ability to selectively identify, collect, and analyze single cells or groups of cells has wide implications in the analysis of forensic samples and the subsequent deconvolution of DNA mixtures, particularly in the processing and interpretation of sexual offense evidence where the deconvolution of heterogeneous sources is essential. Single cell separation technology can be used to address this mixture separation challenge, specifically using the DEPArrayTM system from Menarini Silicon Biosystems. We propose that the DEPArrayTM will enable enhancements to the standard workflow for forensic biology/DNA analytical laboratories. We have demonstrated that the DEPArrayTM workflow will lead to fewer mixture samples, enable purification of sperm and epithelial cell fractions without the need for differential extraction, improve the amplification success rate of samples and improve the interpretation of low template DNA samples. Sperm profiles were identified in 27 of 32 DEPArrayTM processed samples, with 26 of 27 (96.2%) yielding single source profiles. In contrast, single source profiles were obtained from 9 of 28 (32.1%) differentially extracted samples. The use of the DEPArrayTM also eliminates the need for additional confirmatory tests for the presence of human sperm and permits direct identification of the type and number of cells being analyzed eliminating the need for qPCR-based DNA quantification. PMID- 29602062 TI - Reported credibility techniques in higher education evaluation studies that use qualitative methods: A research synthesis. AB - This synthesis study examined the reported use of credibility techniques in higher education evaluation articles that use qualitative methods. The sample included 118 articles published in six leading higher education evaluation journals from 2003 to 2012. Mixed methods approaches were used to identify key credibility techniques reported across the articles, document the frequency of these techniques, and describe their use and properties. Two broad sets of techniques were of interest: primary design techniques (i.e., basic), such as sampling/participant recruitment strategies, data collection methods, analytic details, and additional qualitative credibility techniques (e.g., member checking, negative case analyses, peer debriefing). The majority of evaluation articles reported use of primary techniques although there was wide variation in the amount of supporting detail; most of the articles did not describe the use of additional credibility techniques. This suggests that editors of evaluation journals should encourage the reporting of qualitative design details and authors should develop strategies yielding fuller methodological description. PMID- 29602063 TI - Wandering spleen with horseshoe kidney a rare occurrence. AB - INTRODUCTION: Wandering spleen is a rare clinical entity in itself, with only 2 cases reported thus far when correlated with congenital under-development of the kidney, it usually happens due to under development of its surrounding ligaments. Herein we present a case of wandering spleen with underlying congenital deformity of horseshoe kidney which requires splenectomy due to late presentation. PRESENTATION OF CASE: A 21 year old lady presented with worsening of chronic abdominal pain for 3 years, associated with nausea and vomiting. Physical examination showed a vague mass located at epigastric region. Consecutively, computed tomography images showed a well-defined, oval, hypoechoic spleen extending from center of abdomen up to epigastric region measuring 15.5 * 13 cm with twisted pedicle. Finally the patient underwent surgical treatment. The intraoperative findings were consistent with computed tomography images. The patient made a full recovery and was discharged well. DISCUSSION: Wandering Spleen was first described by Van Horne during autopsy back in 1667. Its location is maintained by peritoneal attachments such as lienorenal, splenocolic, splenophrenic, gastrosplenic and phrenicocolic ligaments. Among which, the gastrosplenic ligament and lienorenal ligaments are of greatest significance. Patient with a wandering spleen may present asymptomatic, with a movable mass in the abdomen, or with chronic or intermittent abdominal pain because of partial torsion and spontaneous de-torsion of the spleen as in our case. When feasible especially in young patients, splenopexy should always be the first consideration but however if gross infarct has occurred then splenectomy is inevitable to save the patient. CONCLUSION: Wandering spleen is a unique surgical entity moreover when appeared in congruence with horseshoe kidney. Its diagnosis should be made in prompt to prevent splenic infarction and to try to salvage with splenopexy especially in younger population. However in patient where splenic torsion with infarction has occurred, splenectomy would be the treatment of choice. PMID- 29602065 TI - Targeting histone demethylases KDM5A and KDM5B in AML cancer cells: A comparative view. AB - Epigenetic modifications play an important role in initiation and progression of cancers including acute myeloid leukemia. Among different epigenetic modifiers, lysine specific demethylases have been noticed as potential therapeutic targets. KDM5 family of histone demethylases which removes methyl marks from lysine residues of H3, are frequently found in the promoter region of transcriptionally active genes resulting in repression of expression. Here we have compared the effects of KDM5A and KDM5B downregulation on HL-60 cell line behavior. KDM5A/5B knockdown resulted in lower viability of HL-60 cells in addition to modified cell cycle distribution and sub-G1 accumulation. Induction of apoptosis was observed in both knockdown cells. But in spite of similarity in their role, downregulation of KDM5A showed more efficient anti-leukemic effects in comparison to KDM5B. Cells showed higher accumulation in sub-G1 and apoptosis occurred significantly higher and also earlier after KDM5A reduction. Expression analysis confirmed almost 5 and 4 fold increased expression for bax and caspase-3 after downregulation of KDM5A in comparison to KDM5B. Due to the present study we propose KDM5A as a potential target for therapeutic aspects of acute myeloid leukemia although further investigations are needed. PMID- 29602064 TI - High-throughput Cos-Seq screen with intracellular Leishmania infantum for the discovery of novel drug-resistance mechanisms. AB - Increasing drug resistance towards first line antimony-derived compounds has forced the introduction of novel therapies in leishmaniasis endemic areas including amphotericin B and miltefosine. However, their use is threatened by the emergence and spread of drug-resistant strains. In order to discover stage dependent resistance genes, we have adapted the Cos-Seq approach through the introduction of macrophage infections in the pipeline. A L. infantum intracellular amastigote population complemented with a L. infantum cosmid library was submitted to increasing concentrations of miltefosine, amphotericin B and pentavalent antimonials in experimental infections of THP-1 cells. For each step of selection, amastigotes were extracted and cosmids were isolated and submitted to next-generation sequencing, followed by subsequent gene-enrichment analyses. Cos-Seq screen in amastigotes revealed four highly enriched loci for antimony, five for miltefosine and one for amphotericin B. Of these, a total of seven cosmids were recovered and tested for resistance in both promastigotes and amastigotes. Candidate genes within the pinpointed genomic regions were validated using single gene overexpression in wild-type parasites and/or gene disruption by means of a CRISPR-Cas9-based approach. This led to the identification and validation of a stage-independent antimony-resistance gene (LinJ.06.1010) coding for a putative leucine rich repeat protein and a novel amastigote-specific miltefosine-resistance gene (LinJ.32.0050) coding for a member of the SEC13 family of WD-repeat proteins. This study further reinforces the power of Cos-Seq approach to discover novel drug-resistance genes, some of which are life-stages specific. PMID- 29602066 TI - New synergistic combinations of differentiation-inducing agents in the treatment of acute promyelocytic leukemia cells. AB - Acute promyelocytic leukemia (APL) was considered to be one of the most lethal forms of leukemia in adults before the introduction of the vitamin A metabolite all-trans retinoic acid (ATRA). Surprisingly, it has been confirmed that FICZ (6 Formylindolo (3, 2-b) carbazole) enhances ATRA-induced differentiation. Moreover, a number of studies have demonstrated that anti CD44 monoclonal antibody (mAb) induces to bring back differentiation blockage the leukemic stem cells. The level of differentiation markers including CD11b and CD11c in NB4 cells was assessed by flow cytometry. The induction of apoptosis was also evaluated. We estimated the induction potential of a triple compound of ATRA-FICZ, anti-CD44 maps. The cells showed the gradually increased expression levels of CD11b and CD11c. A mixture of a "CD44 mAb, ATRA and FICZ effectively promoted granulocytic maturation resulting in increased rates of apoptosis. The differences in expression of CD11b and CD11c at 5 MUg/ml and 10 MUg/ml were significant. These phenomena were highest at 10 MUg/ml CD44 mAb concentrations. Synergistic induction differentiation and apoptosis of APL cells by using a co-treatment with novel triple compound are more effective for eradicating blasts and controlling the metastasis. Our results show that the addition of anti-CD44 mAb improves "ATRA-FICZ"-induced differentiation and has potential to reduce usual chemotherapy based treatments. Taken together, this compound may lead to novel clinical applications of differentiation-based approaches for APL and other types of leukemia. Further clinical studies would be recommended to clarify the clinical efficacy. PMID- 29602067 TI - The use of computed tomography in the diagnosis of abdominal cocoon. AB - BACKGROUND: Literature on the diagnosis of abdominal cocoon using computed tomography (CT) outside the setting of continuous ambulatory peritoneal dialysis is sparse. METHODS: We did a retrospective analysis of contrast enhanced CT done for patients treated for abdominal cocoon. The clinical features, radiological findings, underlying etiology and outcomes were recorded. RESULTS: Of the 22 patients analyzed, 19 had tuberculosis, 2 had malignancy and 1 was idiopathic. The basis of diagnosis of cocoon was CT in 18 and CT and surgery in 4. Types 1, 2 and 3 cocoon were found in 3 (13.63%), 6 (27.27%) and 13 (59.09%) respectively. The bowel findings were clumped loops in 21 (95%), inter-bowel fluid in 13 (59%), bowel wall thickening/enhancement in 6 (27%) and stricture in 1 (5%). Peritoneal thickening and nodularity were seen in 14 (64%) and 2 (9%) while omental thickening, nodularity and mass in 9 (41%), 5 (21%) and 1 (5%). Cauliflower sign was seen in 14 (64%), concertina pattern in 5 (23%) and Bottle Gourd sign in 6 (23%) patients. Of 12 with imaging done during episode of IO, 11 (92%) had cauliflower sign, 4 (80%) had concertina appearance and 6 (100%) had bottle gourd sign. Post treatment weight gain with anti-tubercular therapy was seen in 14 (63.63%), resolution of ascites in 12 (54.54%) and 2 patients had complete resolution of cocoon on repeat imaging. CONCLUSION: CT is a valuable tool for pre operative diagnosis of abdominal cocoon. The classical described signs are seen more frequently in patients with IO. PMID- 29602069 TI - A set of autosomal multiple InDel markers for forensic application and population genetic analysis in the Chinese Xinjiang Hui group. AB - In recent years, insertion/deletion (InDel) markers have become a promising and useful supporting tool in forensic identification cases and biogeographic research field. In this study, 30 InDel loci were explored to reveal the genetic diversities and genetic relationships between Chinese Xinjiang Hui group and the 25 previously reported populations using various biostatistics methods such as forensic statistical parameter analysis, phylogenetic reconstruction, multi dimensional scaling, principal component analysis, and STRUCTURE analysis. No deviations from Hardy-Weinberg equilibrium tests were found at all 30 loci in the Chinese Xinjiang Hui group. The observed heterozygosity and expected heterozygosity ranged from 0.1971 (HLD118) to 0.5092 (HLD92), 0.2222 (HLD118) to 0.5000 (HLD6), respectively. The cumulative probability of exclusion and combined power of discrimination were 0.988849 and 0.99999999999378, respectively, which indicated that these 30 loci could be qualified for personal identification and used as complementary genetic markers for paternity tests in forensic cases. The results of present research based on the different methods of population genetic analysis revealed that the Chinese Xinjiang Hui group had close relationships with most Chinese groups, especially Han populations. In spite of this, for a better understanding of genetic background of the Chinese Xinjiang Hui group, more molecular genetic markers such as ancestry informative markers, single nucleotide polymorphisms (SNPs), and copy number variations will be conducted in future studies. PMID- 29602070 TI - Microbial degradation of Cold Lake Blend and Western Canadian select dilbits by freshwater enrichments. AB - Treatability experiments were conducted to determine the biodegradation of diluted bitumen (dilbit) at 5 and 25 degrees C for 72 and 60 days, respectively. Microbial consortia obtained from the Kalamazoo River Enbridge Energy spill site were enriched on dilbit at both 5 (cryo) and 25 (meso) oC. On every sampling day, triplicates were sacrificed and residual hydrocarbon concentrations (alkanes and polycyclic aromatic hydrocarbons) were determined by GCMS/MS. The composition and relative abundance of different bacterial groups were identified by 16S rRNA gene sequencing analysis. While some physicochemical differences were observed between the two dilbits, their biodegradation profiles were similar. The rates and extent of degradation were greater at 25 degrees C. Both consortia metabolized 99.9% of alkanes; however, the meso consortium was more effective at removing aromatics than the cryo consortium (97.5 vs 70%). Known hydrocarbon-degrading bacteria were present in both consortia (Pseudomonas, Rhodococcus, Hydrogenophaga, Parvibaculum, Arthrobacter, Acidovorax), although their relative abundances depended on the temperatures at which they were enriched. Regardless of the dilbit type, the microbial community structure significantly changed as a response to the diminishing hydrocarbon load. Our results demonstrate that dilbit can be effectively degraded by autochthonous microbial consortia from sites with recent exposure to dilbit contamination. PMID- 29602068 TI - Ectromelia virus lacking the E3L ortholog is replication-defective and nonpathogenic but does induce protective immunity in a mouse strain susceptible to lethal mousepox. AB - All known orthopoxviruses, including ectromelia virus (ECTV), contain a gene in the E3L family. The protein product of this gene, E3, is a double-stranded RNA binding protein. It can impact host range and is used by orthopoxviruses to combat cellular defense pathways, such as PKR and RNase L. In this work, we constructed an ECTV mutant with a targeted disruption of the E3L open reading frame (ECTVDeltaE3L). Infection with this virus resulted in an abortive replication cycle in all cell lines tested. We detected limited transcription of late genes but no significant translation of these mRNAs. Notably, the replication defects of ECTVDeltaE3L were rescued in human and mouse cells lacking PKR. ECTVDeltaE3L was nonpathogenic in BALB/c mice, a strain susceptible to lethal mousepox disease. However, infection with ECTVDeltaE3L induced protective immunity upon subsequent challenge with wild-type virus. In summary, E3L is an essential gene for ECTV. PMID- 29602071 TI - (Ce-Al)-oxide pillared bentonite: A high affinity sorbent for plutonium. AB - The ability of bentonite and montmorillonite pillared by Al-oxide and mixed (Ln Al)-oxides (Ln = La, Ce) to remove 239plutonium solution species from water is comparatively investigated at pH 7 and pH 4. Small-angle scattering and neutron contrast variation with H2O/D2O mixtures is used to verify the ingress of water in the calcined products after hydrophilicity was introduced by an NH3-H2O vapor treatment. The size and shape of the (La/Ce)-Al oxo-hydroxy pillaring cations (2 nm spheres) is determined by small-angle x-ray scattering from the pillaring solutions. Not all of the oxide pillars improved Pu uptake compared with sodium montmorillonite. At neutral and acidic pH only (Ce-Al)-oxide pillared clays showed the ability to remove Pu over the concentration range studied (1.35 * 10-8 8 * 10-8 mol dm-3) with distribution coefficient (KD) values >104. XPS analysis of the (Ce-Al)-oxide pillared clays indicates the presence of Ce4+ as cerium dioxide. The progressive improvement in sorption performance in the order of pillar type Al2O3 < La2O3-Al2O3 << CeO2-Al2O3 reflects the increasing access of Pu solution species to the clay mineral layers by changes to the basal spacing and specific surface area, and also to the higher stability of the (Ce-Al)-oxide pillars. PMID- 29602072 TI - Sex-related responses of European aspen (Populus tremula L.) to combined stress: TiO2 nanoparticles, elevated temperature and CO2 concentration. AB - The combined effects of climate change and chemical contaminants on plant performance are still not well understood. Especially, whether different sexes of dioecious plants respond differently to combined stresses is unknown. In order to study the sex-related responses of European aspen to soil nTiO2 contamination (0, 50, 300 mg kg-1) under elevated temperature (+1.6 degrees C) and CO2 (730 ppm), we conducted a study in greenhouses. Ti accumulated in roots exposed to nTiO2 (1.1-3.3 and 2.7-21.1 mg kg-1 in 50 and 300 mg kg-1 treatments, respectively). Elevated CO2 had no effects on Ti uptake, while elevated temperature increased it in the 300 mg kg-1 treatment. Males grew taller than females under ambient conditions, but females had greater height and biomass increment under elevated temperature. In all climate treatments, nTiO2 increased leaf phenolics in females by 12-19% and 15-26% at 50 and 300 mg kg-1, respectively. Leaf phenolics decreased under elevated temperature, but increased under elevated CO2 in both sexes. Results suggest that females have better chemical defense against nTiO2 than males under future climate conditions. In the longer run, this may cause changes in the competitive abilities of both sexes, which again may affect sex ratios and genetic variation in nature. PMID- 29602073 TI - Role of IL-1beta, IL-6 and TNF-alpha cytokines and TNF-alpha promoter variability in Plasmodium vivax infection during pregnancy in endemic population of Jharkhand, India. AB - BACKGROUND: The combinatorial effects of Plasmodium infection, perturbation of inflammatory responses and the dichotomic role of TNF promoter polymorphism has potential clinical and physiological relevance during pregnancy. OBJECTIVE AND METHODS: This coordinated orchestration instigated us to investigate the circulating level of inflammatory cytokines (IL-1beta, TNF-alpha and IL-6) employing ELISA in a stratified group of samples and the plausible genetic association of TNF-alpha -308 G/A using PCR-RFLP/sequencing during Plasmodium vivax infection in pregnancy. RESULTS: We observed significantly elevated concentrations of IL-1beta were observed, followed by IL-6 and TNF-alpha in women with malaria (WWM) and in malaria in pregnancy (MIP). Further, elevated IL-1beta, followed by TNF-alpha and IL-6 were detected in the non-infected pregnancy group. The differential dynamics of inflammatory cytokine concentration during each trimester of pregnancy with and without P. vivax infection were detected. For the first time, a high level of IL-6 was observed in the first trimester of MIP and high IL-1beta in healthy pregnancies. In the second trimester, however, we observed a high level of IL-1beta in the MIP group compared to a sustained high level of IL-1beta in the healthy pregnancy group. In the third trimester, high IL 1beta was sustained in the MIP group and healthy pregnancies acquired a high TNF alpha level. The genotypic distribution for the TNF-alpha promoter -308 G/A position was observed to be nonsignificant and mildly associated during MIP (OR = 1.4) and in WWM (OR = 1.2). Moreover, based on genotypic distribution, we observed a well-correlated and significantly elevated TNF-alpha concentration in the mutant homozygote genotype (AA; p = 0.001) followed by heterozygotes (GA; p = 0.0001) and ancestral genotypes (GG; p = 0.0001) in both MIP and WWM subjects. CONCLUSION: The observation of elevated IL-1beta and IL-6 in MIP and TNF-alpha in WWM may be regarded as a prognostic inflammatory marker of infection and pregnancy. Most particularly, the TNF-alpha concentration and its polymorphic variability in the promoter region may indicate genetic susceptibility and mildly influence the risk for P. vivax infection during pregnancy and in women with malaria.

AB - The acrylic based hydrogels have attracted the attention of many researchers in the field of pollutants adsorption such as dyes and metal cations due to their high swelling and adsorption capacities. This review introduces acrylic based hydrogels and focuses on their adsorption properties. We first described the methods for synthesizing hydrogels. Usual methods of characterization of acrylic based hydrogels such as swelling, adsorption capacity and desorption efficiency of the pollutants have been investigated. In addition, the adsorption isotherm and kinetic models which determine the mechanism of pollutants' adsorption by hydrogels have been introduced and relations that determine the values of thermodynamic parameters which define accomplishment of adsorption process have been investigated. In the following sections, a perfect insight has been provided on natural and synthetic acrylic based hydrogels. The effective parameters of swelling and adsorption by acrylic based hydrogels have been reviewed and the mechanism of pollutant's adsorption by acrylic based hydrogels has been discussed. PMID- 29602075 TI - An Information System for Brownfield Regeneration: providing customised information according to stakeholders' characteristics and needs. AB - In the EU brownfield presence is still considered a widespread problem. Even though, in the last decades, many research projects and initiatives developed a wealth of methods, guidelines, tools and technologies aimed at supporting brownfield regeneration. However, this variety of products had and still has a limited practical impact on brownfield revitalisation success, because they are not used in their entire potential due to their scarce visibility. Also, another problem that stakeholders face is finding customised information. To overcome this non-visibility and not-sufficient customisation of information, the Information System for Brownfield Regeneration (ISBR) has been developed, based on Artificial Neural Networks, which allows understanding stakeholders' information needs by providing tailored information. The ISBR has been tested by stakeholders from the EU project TIMBRE case studies, located in the Czech Republic, Germany, Poland and Romania. Data gained during tests allowed to understand stakeholders' information needs. Overall, stakeholders showed to be concerned first on remediation aspects, then on benchmarking information, which are valuable to improve practices in the complex field of brownfield regeneration, and then on the relatively new issue of sustainability applied to brownfield regeneration and remediation. Mature markets confirmed their interest for remediation-related aspects, highlighting the central role that risk assessment plays in the process. Emerging markets showed to seek information and tools for strategic and planning issues, like brownfield inventories and georeferenced data sets. Results led to conclude that a new improved platform, combining the ISBR functionalities with geo-referenced ones, would be useful and could represent a further research application.

AB - After the Fukushima Daiichi-Nuclear Power Plant accident, environmental recovery was a major issue because a considerable amount of municipal solid waste incineration (MSWI) fly ash was highly contaminated with radioactive cesium. To the best of our knowledge, only a few studies have evaluated the detailed physicochemical properties of radioactive cesium in MSWI fly ash to propose an effective method for the solidification and reuse of MSWI fly ash. In this study, MSWI fly ash was sampled in Fukushima Prefecture. The physicochemical properties of radioactive cesium in MSWI fly ash were evaluated by particle size classification (less than 25, 25-45, 45-100, 100-300, 300-500, and greater than 500 MUm) and the Japanese leaching test No. 13 called "JLT-13". These results obtained from the classification of fly ash indicated that the activity concentration of radioactive cesium and the content of the coexisting matter (i.e., chloride and potassium) temporarily change in response to the particle size of fly ash. X-ray diffraction results indicated that water-soluble radioactive cesium exists as CsCl because of the cooling process and that insoluble cesium is bound to the inner sphere of amorphous matter. These results indicated that the distribution of radioactive cesium depends on the characteristics of MSWI fly ash.

AB - A well-defined multifunctional brush-type polymeric prodrug covalently linked with an anticancer drug (bufalin, BUF), a tumor-targeting peptide (RGD), and an endosome-escaping polymer, poly(N,N-diethylaminoethyl methacrylate-co-butyl methacrylate (P(DEA-co-BMA)), was developed. Its anticancer performance against colon cancer was investigated in vitro and in vivo. Reversible addition fragmentation transfer (RAFT) polymerization of oligo(ethylene glycol) monomethyl ether methacrylate (OEGMA), 2-((3-(tert-butoxy)-3-oxopropyl)thio)ethyl methacrylate (BSTMA), and 2-(2-bromoisobutyryloxy)ethylmethacrylate (BIEM) afforded the multifunctional random copolymer, P(OEGMA-co-BSTMA-co-BIEM), in which hydrophilic POEGMA can stabilize nanoparticles in water, PBSTMA can be converted into carboxyl groups, and PBIEM can be employed as a macromolecular atom radical transfer polymerization (ATRP) initiator. The ATRP of DEA and BMA using P(OEGMA-co-BSTMA-co-BIEM) as a macromolecular ATRP initiator led to the formation of the pH-responsive brush-type copolymer, P(OEGMA-co-BSTMA)-g-P(DEA-co BMA). After hydrolysis by trifluoroacetic acid and post-functionalization the final polymeric prodrug, P(OEGMA-co-BUF-co-RGD)-g-P(DEA-co-BMA), was obtained with a drug content of ~7.8 wt%. P(OEGMA-co-BUF-co-RGD)-g-P(DEA-co-BMA) can be assembled into nanoparticles (BUF- NP-RGD) in aqueous solution with a diameter of 148.4 +/- 0.7 nm and a zeta potential of -7.6 +/- 0.4 mV. BUF-NP-RGD exhibited controlled drug release in the presence of esterase. Additionally, P(OEGMA-co- BSMA)-g-P(DEA-co-BMA) showed a significant hemolysis effect at a pH comparable to that of endosomes/lysosomes. Cell viability and a tumor-bearing nude mouse model were employed to evaluate the anticancer efficacy of BUF-NP-RGD. It was revealed that BUF-NP-RGD showed improved anticancer performance compared with that of free BUF both in vitro and in vivo. Histological and immunochemical analysis further demonstrated that BUF-NP-RGD exhibited improved cell apoptosis, angiogenesis inhibition, and an anti-proliferation effect.

However, due to its low solubility it can only be administrated intravenously. Nanostructured lipid carriers (NLC) have the ability to encapsulate hydrophobic drugs in an aqueous matrix, making them interesting for use in alternative drug delivery systems for AmB. Their combination with stimuli-sensitive polymers such as alginate can be used as a strategy to protect acid sensitive molecules from gastric acid. The proposal of this work was to develop a dual-strategy hydrogel/NLC delivery system for amphotericin B. NLCs were produced by high pressure homogenization and their size and stability were assessed by dynamic light scattering and electron transmission microscopy. The NLCs presented low cytotoxicity and high selectivity at neutral pH. Alginate hydrogels were successfully produced by the ionic gelation method and characterized using optical microscopy. The hydrogels were tested for their pH-selectivity, cytotoxicity and drug delivery profile. Swelling degree and drug delivery profiles suggested that drug delivery is stimulated as the alginate particles swell and that NLC particles maintain their structure even after rehydration, indicating these systems can be used for oral delivery of AmB. PMID- 29602079 TI - A novel and ultrasensitive electrochemical DNA biosensor based on an ice crystals like gold nanostructure for the detection of Enterococcus faecalis gene sequence. AB - Bacteria, parasites and viruses are found widely in the environment as potential pathogens, and can be the source of infections. Therefore, sensitive and rapid methods for identification of the pathogens are required to achieve a better quality of life. Enterococcus faecalis commonly colonizes and threatens human health. In the present study, we demonstrate the fabrication of a novel electrochemical DNA biosensor based on electrodeposited gold nanostructures as a transducer substrate combined with toluidine blue (TB) as a redox marker. Binding of TB with the single and double stranded DNA (ssDNA and dsDNA) was shortly investigated, and based on the results, TB could discriminate between ssDNA and dsDNA. A specific thiolated ssDNA sequence was immobilized on the transducer substrate, and DNA hybridization was followed by differential pulse voltammetry. The DNA biosensor showed excellent performances with high sensitivity and good selectivity. The DNA biosensor was applied to detect a synthetic target in a linear range of 1.0 * 10-17-1.0 * 10-10 mol L-1 with a limit of detection (LOD) of 4.7 * 10-20 mol L-1. In addition, LOD of the DNA biosensor for the detection of genomic DNA was found to be 30.1 ng MUL-1. PMID- 29602080 TI - Anchoring TGF-beta1 on biomaterial surface via affinitive interactions: Effects on spatial structures and bioactivity. AB - Protein adsorption on biomaterial surfaces is clinically applied to increase therapeutic effects; however, this adsorption is possibly accompanied by conformational changes and results in loss of protein bioactivity or adverse reactions. In this research, a transforming growth factor beta1 (TGF-beta1) affinitive peptide HSNGLPL was grafted onto biopolymer surface to stabilize TGF beta1 spatial conformation after adhesion. The peptide with azide end group was combined with the propynyl pendant group on polyurethane via copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction. The final polymer was characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance spectroscopy, which indicated that the affinitive peptide was introduced to the polymer. Quartz crystal microbalance with dissipation (QCM-D) was performed to monitor TGF-beta1 adsorption and desorption on the surfaces coated with polyurethane with and without peptide combination. Results showed that TGF-beta1 adhered on polyurethane surface and formed a compact and rigid layer. This layer showed spatial structural change but presented a loose and diffuse layer on the peptide-grafted polyurethane surface, indicating stable spatial conformation after adherence. Similar regulations were observed on the two surfaces where BSA layer was coated in advance. In vivo animal experiments revealed that immune reactions and tissue regenerations occurred earlier on peptide-modified polyurethane than on polyurethane, which did not undergo peptide grafting. This finding confirmed that affinitive interactions may preserve TGF beta1 bioactivity on polymer surface after adsorption. PMID- 29602081 TI - Juvenile myoclonic epilepsy refractory to treatment in a tertiary referral center. AB - INTRODUCTION: Juvenile myoclonic epilepsy (JME) is an epileptic syndrome often regarded as one in which seizures are relatively easy to control. Individuals with JME, however, often require lifelong therapy to remain seizure-free, and a few have refractory epilepsy. We ascertained a population with JME and characterized a subgroup with refractory epilepsy. MATERIAL AND METHODS: We audited and reviewed clinical records of individuals diagnosed with JME identified via a sample of 6600 individuals in a clinical database from a specialized epilepsy clinic at a tertiary referral center. RESULTS: We identified 240 people with a diagnosis of JME (146 females), with a mean age at seizure onset of 14.2years (SD: 4.5), and a mean age at diagnosis of 15.6years (SD: 4.9). Clinical phenotypes seen were classic JME phenotype (88%), childhood absence epilepsy evolving into JME (6%), JME with adolescent absences (4%), and JME with astatic seizures (2%). More than a quarter (28%) had a family history of epilepsy. The most commonly used antiepileptic drug (AED) was sodium valproate in 78% of individuals, followed by levetiracetam (64%) and lamotrigine (55%). In the previous year, 47.5% were seizure-free. Using the International League against Epilepsy (ILAE) definitions and considering National Institute for Health and Care Excellence (NICE)-recommended AEDs for this syndrome, 121 individuals (50.4%) were identified as having refractory epilepsy. DISCUSSION: Juvenile myoclonic epilepsy is often regarded as a benign epileptic syndrome, but in this setting, half of the individuals with JME have refractory epilepsy with only about a quarter of those seizure-free in the previous year. Despite some advances in the understanding of this syndrome, there is still much to do before we can offer all the best outcomes. PMID- 29602082 TI - Emotional reactivity in mesial temporal lobe epilepsy: A pilot study. AB - PURPOSE: Emotional reactivity (ER) is the early rapidly evoked response to a salient emotional stimulus which influences an individual's coping mechanisms, eliciting adaptive responses. We investigated ER in patients with mesial temporal lobe epilepsy (MTLE) in order to obtain an emotion-processing measure that can be related to behavioral regulation. METHODS: We measured ER in twelve patients with (MTLE) using the International Affective Picture System (IAPS), the most widely employed instrument to measure ER, and compared their results with those of a matched sample of healthy subjects. Ninety color pictures depicting events with different kinds of affective valence (pleasant, unpleasant, and neutral) were shown to the patients. Unpleasant and pleasant pictures were also distinguished depending on whether or not they involved social human conditions. The ER was rated on the basis of valence and arousal. RESULTS: Patients with MTLE showed higher mean arousal and valence ratings than controls for neutral and socially pleasant pictures. A higher valence for unpleasant pictures and a trend toward significantly higher arousal and valence for pleasant pictures were also recorded. CONCLUSIONS: Patients with MTLE seem to feel the environment in a more sensitive and positive way compared with controls, likely in relationship with social functioning alterations. PMID- 29602083 TI - Antiepileptic drug treatment of generalized tonic-clonic seizures: An evaluation of regulatory data and five criteria for drug selection. AB - BACKGROUND: A generalized tonic-clonic seizure (GTCS) is the most severe form of common epileptic seizure and carries the greatest risk of harm. The aim of this review is to provide an evidence-based guide for the selection of antiepileptic drugs (AEDs) for patients with GTCSs. Eight AEDs are approved in Europe and the USA for the treatment of both primarily GTCSs (PGTCSs) and secondarily GTCSs (SGTCSs) and are considered in this paper. METHODS: Each AED is evaluated using five criteria: (1) efficacy, by seizure type (a: PGTCSs and b: SGTCSs); (2) adverse effects; (3) interactions; (4) adherence and dosing; and (5) mechanism of action (MOA). To ensure the inclusions of robust data, only efficacy data accepted by regulatory authorities were considered, and data related to adverse effects, interactions, adherence, and MOA were all extracted from UK Summaries of Product Characteristics (SPCs). RESULTS: (1a) There is class 1 evidence of the efficacy of only four AEDs in controlling PGTCSs (lamotrigine, levetiracetam, perampanel, and topiramate). (1b) There is no class 1 evidence of the efficacy of any AED in SGTCSs although some evidence from pooled/subgroup analyses or meta analyses supports the use of the four AEDs (levetiracetam, perampanel, topiramate, and with less robust data for lamotrigine). (2) AEDs are associated with different, but to some extent overlapping, common adverse effect profiles but have differing idiosyncratic adverse effects. (3) Pharmacokinetic interactions are seen with most, but not all, AEDs and are most common with carbamazepine and phenytoin. (4) Good adherence is important for seizure control and is influenced by frequency of dosing, among other factors. (5) Mechanism of action is also a consideration in rationalising AED selection when switching or combining AEDs. CONCLUSION: Ultimately, the choice of AED depends on all these factors but particularly on efficacy and adverse effects. Different patients will weigh the various factors differently, and the role of the treating physician is to provide accurate information to allow patients to make informed choices. PMID- 29602084 TI - A comprehensive LC-MS/MS method validation for the quantitative investigation of 37 fingerprint phytochemicals in Achillea species: A detailed examination of A. coarctata and A. monocephala. AB - The current study aims to optimize and validate a comprehensive LC-MS/MS method for the quantification of 37 phytochemicals (15 phenolic acids, 17 flavonoids, 3 non-phenolic organic acids, 1 phenolic aldehyde and 1 benzopyrene) in Achillea species. Though Achillea species were chosen as real life samples, the current method is applicable to a wide range of plant species. The developed method was fully validated in terms of linearity, accuracy (recovery), inter-day and intra day precision (repeatability), limits of detection and quantification (LOD/LOQ) and relative standard uncertainty (U% at 95% confidence level (k = 2)). Reversed phase ultrahigh performance liquid chromatography was optimized to achive optimum separation for 37 phytochemical compounds and to overcome the suppression effects. MS detection was performed using a triple quadrupole mass spectrometer and negative or positive ionization modes were optimized for each analyte. Multiple reaction monitoring (MRM) was used to quantify the analytes, related molecular ions and transition ions were optimized. Phytochemical screening of ethanol and methanol-chloroform extracts of root and aerial parts of A. coarctata and A. monocephala were performed by using the developed and validated LC-MS/MS method. Root and aerial parts of both species have considerable amounts of certain phenolic-nonphenolic acids (quinic, malic, fumaric, chlorogenic and vanillic acids) and flavonoids (rutin, hesperidin, isoquercitrin, apigetrin, luteolin, apigenin). Additionally, total phenolic and flavonoid amounts, antioxidant (DPPH free radical scavenging assay, ABTS radical cation decolorization assay, beta-carotene lipid peroxidation test system and CUPRAC cupper reduction capacity methods), anticholinesterase, tyrosinase, urease inhibition and cytotoxic activities (on HeLa (Human Cervical Carcinoma Cell Line) of A. coarctata and A. monocephala were also investigated. It has been determined that the studied Achillea species, that are rich in total phenolic-flavonoid and chlorogenic acid contents, have high antioxidant and cytotoxic potential at the same time. According to the results of LC-MS/MS, antioxidant and cytotoxic activity studies, after detailed chemical investigation and toxicity studies on these species, A. coarctata and A. monocephala may be promoted as promising sources of natural agents and used for the development of nutraceuticals or functional food ingredients in future. PMID- 29602085 TI - Towards the identification of alkaline phosphatase binding ligands in Li-Dan-Hua Shi pills: A Box-Behnken design optimized affinity selection approach tandem with UHPLC-Q-TOF/MS analysis. AB - Alkaline phosphatase conjugated magnetic microspheres were synthesized via amide reaction, and employed as an effective adsorbent in affinity selection of binding ligands followed by UHPLC-Q-TOF/MS analysis. The analytical validity of the developed approach was evaluated under optimized conditions and the following figures of merit were obtained: linearity, 0.01-0.5 g L-1 with good determination coefficients (R2 = 0.9992); limits of detection (LODs), 0.003 g L-1; and limits of quantitation (LOQ), 0.01 g L-1. The precision (RSD%) of the proposed affinity selection approach was studied based on intra-day (0.8%) and inter-day (1.3%) precisions. Finally, the adsorbent was successfully applied to identification of binding ligands in Li-Dan-Hua-Shi pills and good recoveries were obtained in the range from 96.9 to 99.4% (RSDs 1.6-3.0%). PMID- 29602086 TI - Implementation options for DNA-based identification into ecological status assessment under the European Water Framework Directive. AB - Assessment of ecological status for the European Water Framework Directive (WFD) is based on "Biological Quality Elements" (BQEs), namely phytoplankton, benthic flora, benthic invertebrates and fish. Morphological identification of these organisms is a time-consuming and expensive procedure. Here, we assess the options for complementing and, perhaps, replacing morphological identification with procedures using eDNA, metabarcoding or similar approaches. We rate the applicability of DNA-based identification for the individual BQEs and water categories (rivers, lakes, transitional and coastal waters) against eleven criteria, summarised under the headlines representativeness (for example suitability of current sampling methods for DNA-based identification, errors from DNA-based species detection), sensitivity (for example capability to detect sensitive taxa, unassigned reads), precision of DNA-based identification (knowledge about uncertainty), comparability with conventional approaches (for example sensitivity of metrics to differences in DNA-based identification), cost effectiveness and environmental impact. Overall, suitability of DNA-based identification is particularly high for fish, as eDNA is a well-suited sampling approach which can replace expensive and potentially harmful methods such as gill netting, trawling or electrofishing. Furthermore, there are attempts to replace absolute by relative abundance in metric calculations. For invertebrates and phytobenthos, the main challenges include the modification of indices and completing barcode libraries. For phytoplankton, the barcode libraries are even more problematic, due to the high taxonomic diversity in plankton samples. If current assessment concepts are kept, DNA-based identification is least appropriate for macrophytes (rivers, lakes) and angiosperms/macroalgae (transitional and coastal waters), which are surveyed rather than sampled. We discuss general implications of implementing DNA-based identification into standard ecological assessment, in particular considering any adaptations to the WFD that may be required to facilitate the transition to molecular data. PMID- 29602087 TI - Development of a protocol for environmental impact studies using causal modelling. AB - 1- A major challenge when assessing the impacts of human activities on the globe's natural resources is to account for the impacts of land use versus natural spatiotemporal variation in system dynamics. Current freshwater assessments are unable to resolve spatiotemporal confounding through study designs or statistical analyses. Observational studies typically fail to consider the period-by-location interaction in the absence of an impact. 2- Here, I address the problem of spatiotemporal confounding using causal modelling based on spatiotemporal data to infer causal effects of wastewater on biotic ecosystems. A combination of statistical analysis and causation theory was used to address confounding bias. Benthic macroinvertebrate and environmental variable data were collected from locations upstream and downstream of a wastewater treatment plant discharge point in south-eastern Australia over 1.5 years. The composite hypotheses based on the theoretical relationships among these variables were summarised in a causal diagram. Model building and testing was conducted using Structural Equation Modelling (SEM). Distance-based redundancy analysis (dbRDA) was used for model building and hypothesis testing. 3- The results indicated that the causal effects of effluent on macroinvertebrate communities could be inferred using causal modelling. The macroinvertebrate communities responded to water quality degradation with a clear shift in community composition after the discharge point and this change varied seasonally. Chlorophyll a, total organic carbon, zinc, conductivity, temperature, and its interaction with conductivity, were important determinants of the macroinvertebrate community composition. Causal models also explained the spatiotemporal variations in environmental variables. The consistency of data with the structure of the causal diagram was confirmed with global Fisher's C-test. 4- Causal modelling has been shown to be a useful tool in environmental impact studies. In this study, the usefulness of causal modelling was attributed to its proficiency in combining all of the elements necessary for an efficient risk assessment through dealing with spatial and temporal confounding, facilitating communication between scientists and resource managers, and supporting management decision making. PMID- 29602088 TI - Interactions of natural organic matter on the surface of PVP-capped silver nanoparticle under different aqueous environment. AB - It is now widely accepted that coating on the nano-surface would critically dictate the uptake and cytotoxicity of engineering nanomaterials. However, the influence of natural organic matter (NOM) on the surface is quite limited to humic substances, while the diversity of NOM is neglected. In the present study, we tried to investigate the change of surface in the coexistence of bovine serum albumin (BSA) and humic acid (HA). The isothermal titration calorimetric measurements show that HA can combine with BSA in both freshwater or seawater, however, the patterns are different. In freshwater, HA lowered the adsorption of BSA on PVP-capped AgNPs through complexation with BSA, which prevented the contact of sulfur in BSA with PVP-AgNPs. Then in seawater, BSA retained its sulfur availability to bind with PVP-AgNPs. Furthermore, the toxicity of PVP AgNPs incubated in the BSA/HA solution was evaluated by measuring the level of reactive oxygen species generated by Escherichia coli. The results indicated that, in seawater, the adsorbed BSA promoted the toxicity of PVP-AgNPs in the presence of Ca2+ and Mg2+, but the presence of HA limited this effect. PMID- 29602089 TI - Women's asset ownership and children's nutritional status: Evidence from Papua New Guinea. AB - This study examines how women's asset ownership is associated with children's nutritional status in Papua New Guinea, a country with some of the most severe child malnutrition in the world. The 2009-2010 Household Income and Expenditure Survey is employed, but restricted to children under the age of 72 months living with married mothers, leaving a final analytic sample of 1651. Asset ownership is expected to strengthen mothers' income-generating capacity and their bargaining power within the home, which increases investments in children's health. Women's ownership of fishing and agricultural equipment (important for meeting subsistence needs and for generating cash earnings) appears to be driving most of the results. OLS regression results point to beneficial effects of maternal asset ownership for children's height-for-age, weight-for-height, and weight-for-age Z scores, and results from detailed quantile regressions indicate that these effects occur at various parts of the distribution, especially for children's WAZ scores. PMID- 29602090 TI - Male-female differences in households' resource allocation and decision to seek healthcare in south-eastern Nigeria: Results from a mixed methods study. AB - Ability to influence household decision-making has been shown to increase with improved social capital and power and is linked to better access to household financial resources and other services outside the household including healthcare. To examine the male-female differences in household custody of financial resources, decision-making, and type of healthcare utilised, we used a mixed methods approach of cross-sectional household surveys and focus-group discussions (FGDs). Data was collected between 10 January-28 February 2011. We analyzed a sample of 411 households and a sub-sample of 223 households with a currently married head. We conducted six single-sex FGDs in 3 communities (1 urban, 2 rural) among a random sub-sample of participants in the survey. We performed univariate, bivariate, and logistic regression analyses with a 95% confidence interval. For the qualitative data, we performed thematic analysis where broad themes relevant to the research objective were abstracted. In all households and in those with a married head, sick male members were less likely to forgo healthcare (aORall0.87, 95% CI 0.80-0.90; aORmarried0.52, 95% CI 0.18 0.83) and more likely to utilise formal healthcare relative to female sick members (aORall3.36, 95% CI 3.20-3.87; aORmarried19.50, 95% CI 9.62-39.52). Formal healthcare providers are medically trained while informal providers are untrained vendors that dispense medications for profit. There were more reports of sole custody of household resources among men within households with married heads. Joint decision-making on healthcare expenditure improved women's access to healthcare but is not reflective of unhindered access to household financial resources. Qualitatively, women spoke of seeking permission from male household head before expenditure was incurred, while male heads spoke of concealing household financial resources from their spouse. Gender constructs and male female differences have important effects on household resource allocation and healthcare utilisation. PMID- 29602092 TI - Removal of priority and emerging pollutants from aqueous media by adsorption onto synthetic organo-funtionalized high-charge swelling micas. AB - In this work, the removal of different types of emerging pollutants (four perfluoroalkyl compounds, two preservatives, three surfactants and nine pharmaceutical compounds) from aqueous solution by adsorption onto two novel synthetic clays, a high-charge swelling mica (Na-Mica-4) and an organo functionalized mica (C18-Mica-4), was evaluated. Na-Mica-4 and C18-Mica- 4 were prepared and characterized by X-Ray diffraction, Zeta potential, specific surface area, thermogravimetric analysis and transmission electron microscopy, before and after adsorption experiments. The influence of the aqueous sample pH, salt addition and extraction time in the removal were evaluated. The results showed the high adsorption affinity of C18-Mica-4 for most of the emerging pollutants analysed after a removal time of 24 h (14 out of 18 pollutants were effectively removed [70-100%]). A high correlation was observed between the log Kow of the selected emerging pollutants and the adsorption onto C18-Mica-4. The results also indicate that adsorption occurs in the interlayer space. While the removal rates with Na-Mica-4 were in the range 8-97% after seven days, some of the compounds, perfluorobutanoic acid and most of pharmaceutically active compounds, were not adsorbed onto the high-charge mica. C18-Mica- 4 was effectively used for the removal of contaminants from four types of water samples. PMID- 29602091 TI - Developing religiously-tailored health messages for behavioral change: Introducing the reframe, reprioritize, and reform ("3R") model. AB - RATIONALE: As community health interventions advance from being faith-placed to authentically faith-based, greater discussion is needed about the theory, practice, and ethics of delivering health messages embedded within a religious worldview. While there is much potential to leverage religion to promote health behaviors and improve health outcomes, there is also a risk of co-opting religious teachings for strictly biomedical ends. OBJECTIVE: To describe the development, implementation, and ethical dimensions of a conceptual model for religiously-tailoring health messages. METHOD: We used data from 6 focus groups and 19 interviews with women aged 40 and older sampled from diverse Muslim community organizations to map out how religious beliefs and values impact mammography-related behavioral, normative and control beliefs. These beliefs were further grouped into those that enhance mammography intention (facilitators) and those that impede intention (barriers). In concert with a multi-disciplinary advisory board, and by drawing upon leading theories of health behavior change, we developed the "3R" model for crafting religiously-tailored health messages. RESULTS: The 3R model addresses barrier beliefs, which are beliefs that negatively impact adopting a health behavior, by (i) reframing the belief within a relevant religious worldview, (ii) reprioritizing the belief by introducing another religious belief that has greater resonance with participants, and (iii) reforming the belief by uncovering logical flaws and/or theological misinterpretations. These approaches were used to create messages for a peer-led, mosque-based, educational intervention designed to improve mammography intention among Muslim women. CONCLUSIONS: There are benefits and potential ethical challenges to using religiously tailored messages to promote health behaviors. Our theoretically driven 3R model aids interventionists in crafting messages that address beliefs that hinder healthy behaviors. It is particularly useful in the context of faith-based interventions for it highlights the ethical choices that must be made when incorporating religious values and beliefs in tailored messages. PMID- 29602093 TI - Fate of leaf litter deposits and impacts on oxygen availability in bank filtration column studies. AB - Degradation of particulate organic carbon (POC) such as leaf litter might deplete dissolved oxygen within the upper layers of bank filtration, an efficient and robust barrier for pathogens and for various organic micro-pollutants (OMP) in water supply systems worldwide. The degradation of OMP during bank filtration depends on the redox conditions. The present study aimed at identifying the impacts and fates of different local leaves on the oxygen consumption and the possible biological degradation of indicator OMP. Oxygen concentrations initially decreased within the columns from around 8 mg/L in the influent to low concentrations indicating extensive consumption within a short travel distance. Still a substantial oxygen consumption was observed after 250 days. OMP concentrations were not significantly affected by the microbial processes. A layer of calcium carbonate crystallites was observed on the POC layer. Some leaf fragments appeared to be persistant towards degradation and the carbon content relative to nitrogen and sulfur contents decreased within 250 days. The results demonstrate that trees at bank filtration sites might have a strong long-term impact on the subsurface redox conditions. PMID- 29602094 TI - Dose-response relationship between blood lead levels and hematological parameters in children from central China. AB - BACKGROUND: Lead is a heavy metal that can affect the human hematological system. However, reports are limited on the dose-response relationship between blood lead levels (BLLs) and hematological parameters in children. This study aimed to explore the dose-response relationship between BLLs and hematological measurements among children in China. METHODS: A cross-sectional design was used. A total of 743 children aged 5-8 years were recruited from two counties in central China. The BLLs and blood levels of iron, zinc, and calcium were determined, and hematological parameters were measured. RESULTS: All hematological measurements and BLLs were logarithm-transformed to ensure a normal distribution. The geometric mean of the BLLs of all children was 82.4 MUg/L. Forty-one percent of the children had BLLs >= 100 MUg/L. The lead-poisoning percentages of the children were significantly associated with gender, age, district of residence, and environmental lead exposure level. Multivariate linear regression analyses showed no significant linear correlation between BLL and each hematological parameter among the children with BLLs >= 100 MUg/L. The analyses also revealed a small increase in red blood cell count (RBC) with increasing BLLs in the BLLs < 100 MUg/L group (beta = 0.03, P = 0.048). A negative association was noted between BLLs and blood platelet (PLT) count in the children with BLLs < 100 MUg/L (beta = -0.90, P < 0.001). Logistic regression analyses showed that BLLs were significantly associated with decreased hemoglobin (Hb) levels, RBC counts, PLT counts and mean corpuscular hemoglobin (MCH) after adjusting for potential confounders. Such analyses also revealed a dose-response relationship between the BLLs and hematological parameters (Hb level, RBC count, and PLT count). The children with BLLs >= 100 MUg/L were 2.72, 2.51, and 3.76 times more likely to achieve decreased RBC counts, Hb levels and PLT counts, respectively, compared to those with BLLs < 100 MUg/L. Compared with children with BLLs < 100 MUg/L, those with BLLs >= 100 MUg/L were 3.16 and 4.38 times more likely to show decreased Hb levels and PLT counts respectively in the high-level lead-exposure group and 4.33 times more likely to achieve a decreased PLT count in the low level lead-exposure group. The individuals with BLLs of the highest quartile were 3.65, 5.87, and 29.23 times more likely to exhibit decreased Hb levels, RBC counts, and PLT counts, respectively, than the children with BLLs of the lowest quartile. CONCLUSION: Our findings suggested a negative association between BLLs and hematological indicators (Hb level, RBC count, PLT count and MCH). A strong negative, non-linear dose-response relationship was also showed between BLLs and hematological parameters (Hb level, RBC count, and PLT count).

AB - BACKGROUND: Acute varicella zoster virus (VZV) replication in shingles is accompanied by VZV antibody boosting. It is unclear whether persisting virus shedding affects antibody levels. OBJECTIVES: To investigate the relationship between VZV viral load and antibody titres in shingles patients during six months following diagnosis and assess whether VZV antibody titre could discriminate patients with recent shingles from healthy population controls. STUDY DESIGN: A prospective study of 63 patients with active zoster. Blood samples were collected at baseline, one, three and six months to measure VZV DNA and IgG antibody titre. We compared VZV antibody titres of zoster patients and 441 controls. RESULTS: In acute zoster, viral load was highest at baseline and declined gradually over the following six months. Mean antibody titres rose fourfold, peaking at one month and remaining above baseline levels throughout the study. Antibody levels at one, three and six months after zoster were moderately correlated with baseline but not subsequent viral load. Regarding use of antibody titres to identify recent shingles, to achieve 80% sensitivity, specificity would be 23.4%, 67.7%, 64.8% and 52.6%, at baseline, visit 2, 3 and 4 respectively, whilst to achieve 80% specificity, sensitivity would be 28.3%, 66.1%, 52.6%, 38.6%, at baseline, visit 2, 3 and 4 respectively. CONCLUSIONS: Clinical VZV reactivation boosted VZV antibody levels and the level of boosting was dependent upon baseline viral replication. While antibody titres could discriminate patients with shingles 1-6 months earlier from blood donor controls, there was a large trade-off between sensitivity and specificity.

AB - BACKGROUND: Hepatitis E virus (HEV) infection is increasingly recognized as a cause of hepatitis in developed countries. A high HEV IgG seroprevalence in humans and pigs is reported as well as sporadic clinical cases of autochtonous HEV but there are currently no data available on the clinical burden of HEV in Belgium. OBJECTIVES: The objective of the current study was to evaluate the actual clinical burden of HEV infections in our tertiary care center in Flanders, Belgium. STUDY DESIGN: In the setting of Ghent University Hospital, patients were assessed for the presence of HEV IgG and IgM as well as HEV RNA if no other cause was found for one of the following clinical presentations: a) elevation of liver enzymes in post-liver transplant; b) suspicion of acute or toxic hepatitis; c) unexplainable elevation of liver enzymes; d) cirrhosis with acute-on-chronic exacerbation. RESULTS: In a period of 39 months (January 2011-April 2014) 71 patients were enrolled. HEV IgG was found positive in 13 (18,3%) patients; HEV IgM in 6 patients (8,5%) and HEV RNA in 4 (5,6%) patients. All HEV IgM/RNA positive patients were male, aged 41-63, and classified in the clinical groups a), b) or d). HEV IgG seroprevalence was slightly higher but not significantly different from the seroprevalence in the general population in this region in Belgium previously reported to be 14% (p-value 0.41) by our group. CONCLUSIONS: HEV should be considered as a cause of liver pathology especially in middle-aged men with elevation of liver enzymes.

In the context of uranium mining, peat can accumulate high concentrations of uranium and its decay products such as radium. Hence, interaction with peat appears to be a key factor in the understanding of the geochemical mechanisms controlling the fate of these products. This study aims to determine the sorption properties of two trace elements, U(VI) and 226Ra, on natural organic matter from peat. The presented method was applied to both natural peat samples originating from a mining context, with various contents of organic matter (from 40 to 70%) and detrital loads, and wetland peat with a more than 98% composition of organic matter. In the present study, considering peat material as a sorbent, its reactivity towards metals and other contaminants can be described as that of an ion-exchanger. A relatively simple model of ion exchange based on the sorption properties of carboxylic sites has been applied with success to describe the sorption of uranium and radium. In the general overview of the different mechanisms able to control the mobility of these radionuclides in a uranium mining context, organic matter is likely one of the main contributors to radionuclide scavenging even under oxic conditions.

AB - Schorl could perform as an extremely promising catalyst for decomposing tetracycline hydrochloride (TC) due to its high degradation efficiency, low cost, chemical stability, easy recovery and repeatable utilization. Comparisons of TC degradation indifferent systems showed that schorl/H2O2 system exhibited the optimum pollutant elimination and TOC removal efficiencies. Kinetics and possible mechanisms of TC degradation were clarified. The OH generated on the schorl surface and O2-/HO2 were the main reactive species responsible for TC oxidation. Six possible intermediates were identified, and possible transform mechanisms and pathways were explored. Active radicals were inclined to attack the CC double bond, dimethylamino and phenolic moieties of TC molecular. The principal intermediate products were generated through N-demethylation, oxidation and rearrangement.

AB - A recyclable titanium nanofibers, doped with cerium and nickel doped was successfully synthesized by using sol-gel and electrospinning method for hydrogen generation from alkali free hydrolysis of NaBH4. The resultant nanocomposite was characterized to find out the structural and physical-chemical properties by a series of analytical techniques such as FT-IR (Fourier transform infrared spectroscopy), XRD (X-ray diffraction), SEM (scanning electron microscope), EDX (energy-dispersive X-ray spectroscopy),N2 adsorption-desorption and BET (Brunauer Emmett-Teller), etc. The results revealed that cerium and nickel nanoparticles were homogeneously distributed on the surface of the TiO2 nanofibers due to having similar oxidation state and atomic radium of TiO2nanofibers with CeO2 and NiO for the effective immobilization of metal ions. The NiO doped catalyst showed superior catalytic performance towards the hydrolysis reaction of NaBH4 at room temperature. These catalysts have ability to produce 305 mL of H2 within the time of 160 min at room temperature. Additionally, reusability test revealed that the catalyst is active even after five runs of hydrolytic reaction, implying the as prepared NiO doped TiO2 nanofibers could be considered as a potential candidate catalyst for portable hydrogen fuel system such as PEMFC (proton exchange membrane fuel cells).

AB - Aerosol acidity has significant implications for atmospheric processing, and high time-resolution measurements can provide critical insights into those processes. This paper reports diurnal variations of aerosol acidity characterized using an open thermodynamic system in Guangzhou, China. Hourly measurements of PM2.5 associated ionic species and related parameters were carried out during June September 2013 followed by application of the Extended Aerosol Inorganic Model in open mode to estimate aerosol pH. The model-estimated aerosol pH was 2.4 +/- 0.3, and the pH diurnal profile exhibited peaks in the early morning (6 a.m.) and troughs in the afternoon (2 p.m.) that appeared to be constrained by liquid water content (LWC) and free H+. A linear regression model was developed to predict aerosol pH, which performed strongly with 4 variables during daytime (NH4+, Na+, SO42- and RH; R2 = 0.95) and 3 during nighttime (NH4+, SO42- and RH; R2 = 0.91). The effect of aerosol acidity on the partitioning of HNO3, HCl and NH3 was studied based on theoretical considerations and measurement data. The fractions in particulate phase for acidic compounds correlated strongly with pH (R2 = 0.64 0.69) while that for NH3, interestingly, was weak (R2 = 0.17). Analytical expressions were developed to explain these observations and it was concluded that the partitioning of HCl and HNO3 was more sensitive to pH compared to that of NH3. These results are significant in terms of potential atmospheric depletion rates of HCl and HNO3 in the region and stress the need for future studies in this direction.

AB - Composted urban biowaste-derived substances (BBS-GC) are used as carbon sources for the preparation of carbon-coated magnet-sensitive nanoparticles obtained via co-precipitation method and the subsequent thermal treatment at 550 degrees C under nitrogen atmosphere. A multitechnique approach has been applied to investigate the morphology, magnetic properties, phase composition, thermal stability of the obtained magnet-sensitive materials. In particular, pyrolysis induced modifications affecting the BBS-GC/carbon shell were highlighted. The adsorption capacity of such bio-derivative magnetic materials for the removal of hydrophobic contaminants such as polycyclic aromatic hydrocarbons was evaluated in order to verify their potential application in wastewater remediation process. The promising results suggest their use as a new generation of magnet-responsive easily-recoverable adsorbents for water purification treatments. PMID- 29602102 TI - Immobilization of ligninolytic enzymes from white-rot fungi in cross-linked aggregates. AB - Ligninolytic enzymes from white-rot fungi are widely used in biotechnological processes. However, the application of these enzymes as free enzymes is limited due to their instability and lack of reusability. Enzyme stabilization is therefore a major challenge in biocatalytic process research, and immobilization methods are desirable. Using cross-linked enzyme aggregates (CLEAs) such as magnetic CLEAs, porous-CLEAs and combi-CLEAs is a promising technique for overcoming these issues. Cross-linking methods can stabilize and immobilize enzymes by interconnecting enzyme molecules via multiple bonds using cross linking agents such as glutaraldehyde. The high catalyst density and microporous assembly of CLEAs guarantee high catalyst activity, which, together with their long shelf life, operational stability, and reusability, provide a cost-efficient alternative to matrix-assisted immobilization approaches. Here, we review current progress in ligninolytic enzyme immobilization and provide a comprehensive review of CLEAs. Moreover, we summarize the use of these CLEAs for biocatalysis processes, bioremediation such as dye decolourization, wastewater treatment or pharmaceutically active compound elimination.

AB - Recently, feed spacer research for improving the performance of a membrane module has adopted three-dimensional (3D) printing technology. This study aims to improve the performance of membrane feed spacers by using various materials and incorporating 3D printing. The samples were fabricated after modeling with 3D computer-aided design (CAD) software to investigate the mechanical strength, water flux, reverse solute flux, and fouling performances. This research was performed using acrylonitrile butadiene styrene (ABS), polypropylene (PP), and natural polylactic acid (PLA) as printing material, and the spacer model was produced using a diamond-shaped feed spacer, with a commercially available product as a reference. The 3D printed samples were initially compared in terms of size and precision with the 3D CAD model, and deviations were observed between the products and the CAD model. Then, the spacers were tested in terms of mechanical strength, water flux, reverse solute flux, and fouling (alginate-based waste water was used as a model foulant). Although there was not much difference among the samples regarding the water flux, better performances than the commercial product were obtained for reverse solute flux and fouling resistance. When comparing the prominent performance of natural PLA with the commercial product, PLA was found to have approximately 10% less fouling (based on foulant volume per unit area and root mean square roughness values), although it showed similar water flux. Thus, another approach has been introduced for using bio degradable materials for membrane spacers. PMID- 29602104 TI - Geographical variations of cadmium and arsenic concentrations and arsenic speciation in Chinese rice. AB - Rapid industrialization in China in recent decades has resulted in soil contamination in some areas, raising the concern about food safety. Consumption of rice represents a major exposure route for the toxic elements cadmium (Cd) and arsenic (As). We collected 160 polished rice from local markets in 20 provinces in China and determined total Cd and As concentrations and As speciation. Total Cd concentration ranged from below the detection limit to 0.77 mg kg-1, with 10% of the samples exceeding the Chinese limit (0.2 mg kg-1). Rice Cd concentration showed a distinct geographical pattern, increasing from low levels in the north to high levels in the south of China. Median daily Cd intake from rice varied from 0.01 MUg kg-1 body weight in the north to 0.61 MUg kg-1 body weight in the south of China, representing between 1% and 73% of the tolerable daily intake (TDI) recommended by FAO/WHO. The highest median Cd intake from rice was in Hunan province with 2 times TDI. Total As concentration ranged from 0.011 to 0.186 mg kg-1, with inorganic As (iAs) and dimethylarsinic acid (DMAs) on average accounting for 69% and 31%, respectively. All samples were below the Chinese limit for iAs in rice (0.2 mg kg-1). There was no clear geographical pattern in rice total As concentration, but rice produced in northeastern China contained higher percentages of DMAs and lower percentages of iAs. This study highlights a high risk of Cd exposure from rice consumption for the population of southern China and suggested strategies for reducing Cd accumulation in rice crop. PMID- 29602105 TI - Application of a rotating impeller anode in a bioelectrochemical anaerobic digestion reactor for methane production from high-strength food waste. AB - In this study, a practical bioelectrochemical anaerobic digestion (BEAD) reactor equipped with a rotating STS304 impeller was tested to verify its methane production performance. Methane production in the BEAD reactor was possible without accumulation of volatile fatty acids (VFAs) and decreases in pH at high organic loading rates (OLRs) up to 6 kg-COD/m3.d (COD: chemical oxygen demand). Methane production in a BEAD-O (open circuit) reactor was inhibited at OLRs above 4 kg-COD/m3.d; however, the performance could be recovered bioelectrochemically by supplying voltage. The population density of hydrogenotrophic methanogens increased to 73.3% in the BEAD-C (closed circuit) reactor, even at high OLRs, through the removal of VFAs and conversion of hydrogen to methane. The energy efficiency in the BEAD-C reactor was 85.6%, indicating that the commercialization of BEAD reactors equipped with rotating STS304 impeller electrodes is possible. PMID- 29602106 TI - Enrichment of sulfate reducing anaerobic methane oxidizing community dominated by ANME-1 from Ginsburg Mud Volcano (Gulf of Cadiz) sediment in a biotrickling filter. AB - This study was performed to enrich anaerobic methane-oxidizing archaea (ANME) present in sediment from the Ginsburg Mud Volcano (Gulf of Cadiz) in a polyurethane foam packed biotrickling filter (BTF). The BTF was operated at 20 (+/-2) degrees C, ambient pressure with continuous supply of methane for 248 days. Sulfate reduction with simultaneous sulfide production (accumulating ~7 mM) after 200 days of BTF operation evidenced anaerobic oxidation of methane (AOM) coupled to sulfate reduction. High-throughput sequence analysis of 16S rRNA genes showed that after 248 days of BTF operation, the ANME clades enriched to more than 50% of the archaeal sequences, including ANME-1b (40.3%) and ANME-2 (10.0%). Enrichment of the AOM community was beneficial to Desulfobacteraceae, which increased from 0.2% to 1.8%. Both the inoculum and the BTF enrichment contained large populations of anaerobic sulfur oxidizing bacteria, suggesting extensive sulfur cycling in the BTF. PMID- 29602107 TI - Efficient elimination of sulfonamides by an anaerobic/anoxic/oxic-membrane bioreactor process: Performance and influence of redox condition. AB - Membrane bioreactors (MBRs) were shown contradictory results for the removal of antibiotics, such as sulfonamides (SAs), from wastewater in different studies, which highlighted the necessity for comprehensive investigation on removal mechanisms of sulfonamides in well-controlled lab-scale MBRs. In the present study, the removal performance of nine SAs by a lab-scale anaerobic/anoxic/oxic membrane bioreactor (A1/A2/O-MBR) was studied at environmental relevant concentrations. The results showed that all the SAs were efficiently eliminated (93.9%-97.5%) in the A1/A2/O-MBR, much more efficiently than the previously reported MBR-based processes. The largest contribution to the total removal was made by the aerobic reactor (71.1%-85.3%) A small portion of SAs (7.1%-22.5%) were removed by anoxic reactor. Activated sludge in the A1/A2/O-MBR was harvested to conduct batch experiments to further study the removal and degradation kinetics of SAs under anaerobic, anoxic and aerobic conditions. The results indicated that only sulfisoxazole could be removed under anaerobic condition. Modest biodegradation of individual SAs (15-33%) was observed under anoxic condition. Under aerobic condition, most investigated SAs underwent an efficient and fast removal (68-77%) in 6h without a lag phase; while sulfisomidine and sulfamethazine were removed less efficiently (approximately 47% after 6h reaction). The aerobic and anoxic degradation of SAs fitted the first-order kinetics model well, and the obtained biodegradation rate constants (k1) were reliable to predict removal efficiencies of SAs in the anoxic and aerobic reactor of A1/A2/O-MBR based on their HRTs. PMID- 29602108 TI - Filling the missing data gaps of daily MODIS AOD using spatiotemporal interpolation. AB - Aerosol is an important component of the atmosphere that affects the environment, climate, and human health. Remote sensing is an efficient observation method for monitoring global aerosol distribution and changes over time. The daily Moderate Resolution Imaging Spectroradiometer (MODIS) level-2 aerosol optical depth (AOD) (Collection 6) product (10 km resolution) is often used to study climate change and air pollution. However, the product is prone to yielding large amounts of data gaps due to the unfeasibility of retrieving reliable estimates under cloudy conditions, and these data gaps inevitably affect the results and analysis of the product's application. In this study, a geostatistical data interpolation framework based on the spatiotemporal kriging method was implemented to interpolate satellite AOD products in Beijing, China. Compared to the ordinary kriging method for filling data gaps, the spatiotemporal interpolation not only utilizes spatial autocorrelation but also considers the temporal and spatiotemporal autocorrelations between different locations. In the study region, the completeness of the spatiotemporal-interpolated AOD product reaches 67.73%, which is significantly superior to the completeness of the original MODIS product (14.27%) and that of the spatial kriging-interpolated AOD product (33.3%). The cross-validation results show that the mean absolute error of the spatiotemporal kriging results (0.07) is lower than that of the ordinary kriging (0.09).

PMID- 29602110 TI - Degradation and dispersion limit environmental DNA detection of rare amphibians in wetlands: Increasing efficacy of sampling designs. AB - The detection of rare macroorganisms using environmental DNA (eDNA) is a powerful new method for conservation and management; the efficacy of this method is affected by physiological, ecological, and hydrological processes. Understanding the processes limiting eDNA detection and accounting for those factors with optimized sampling designs is critical for realizing the potential of this tool. Amphibians are a focus of conservation programs globally and are often difficult to detect, presenting a challenge for effective action. To increase the ability of eDNA techniques to inform conservation and management programs, we investigated the eDNA detection of amphibians compared with field surveys for six species across a gradient of environmental factors expected to affect eDNA detection in three different systems: perennial wetlands, intermittent wetlands, and acidic intermittent wetlands. We applied a baseline sampling design in each wetland and used an occupancy modeling approach to evaluate evidence for processes limiting detection for each species given the presence of the target species. Evidence weights indicated that limiting processes varied across systems and included those associated with increased degradation (pH<5, temperature>25 degrees C) and limited dispersion (wetland area>1200m2, sample volume<200mL). Optimized sampling protocols based on model results included an increased number of sampling locations in large and highly degradative (acidic) wetlands and increased filter pore size in high-particulate systems. These improved designs compensated for the previously limiting factors and yielded average detection rates of 0.62-0.86 per water sample. Degradation and dispersion processes appear to strongly influence the detection of amphibians in wetlands. Optimized, adaptive sampling designs can greatly increase the efficacy of eDNA monitoring approaches. PMID- 29602111 TI - Formulation approaches to reduce post-application pesticide volatilisation from glass surfaces. AB - Volatilisation is one of the main pathways for pesticide emission to the atmosphere. While formulation strategies and adjuvants are known to affect the fate of active ingredient, no general volatilisation reducing guidelines exist for formulation purposes. Moreover, as limited information on formulation effects is available, current pesticide fate models lack parameters characterising reduction of active ingredient volatilisation. The objective of this study was to investigate the volatilisation reducing potential of formulation types and adjuvants, and to propose an effective vapour pressure for pesticide fate modelling. Several formulations of fenpropimorph, pyrimethanil and tebuconazole were produced and tested in a wind tunnel to evaluate the effect of formulation on active ingredient volatilisation. Produced emulsifiable concentrates with high volatile solvents did not offer any reduction in volatilisation, while the low volatile solvent reduced the volatilisation of pyrimethanil and fenpropimorph with 79.2 and 52.9%, respectively. The microemulsion reduced the volatilisation of fenpropimorph, pyrimethanil and tebuconazole with 57.6, 57.8 and 49.8%, respectively. High surfactant-active ingredient ratios (100:1) reduced the volatilisation of applied amount of pyrimethanil with 50%, on average. The effective vapour pressure of pyrimethanil formulated as a commercial available suspension concentrate was reduced by 33.8%. The commercial available emulsifiable concentrate did not reduce volatilisation of fenpropimorph. Effective vapour pressures of formulated fenpropimorph and pyrimethanil were determined and showed a high correlation with the amount volatilised within 48h. The saturated vapour pressure is useful when comparing the volatility of active ingredients, but effective vapour pressures are more appropriate to be used in pesticide fate models. PMID- 29602112 TI - Long-term monitoring programme of polychlorinated dioxins and polychlorinated furans in ambient air of Catalonia, Spain (1994-2015). AB - Reductions in concentrations of persistent organic pollutants were observed for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in a comparison of two consecutive decades ending in December 31, 2015 (n = 413) and compiled from a 48-station long-term air-monitoring network in Catalonia, Spain. Reductions were observed in geometric mean concentration of total PCDD/Fs, decreasing at a rate of 11% yr-1. Results reflect the relative success of improved pollution control measures at industry and traffic locations. At traffic and industrial locations, PCDD/Fs were reduced by around 68% (from 70 to 22 fg I-TEQ/m3) and 66% (from 57 to 19 fg I-TEQ/m3), respectively. The highest concentration of 1196 fg I-TEQ/m3 was observed during the first decade at an industrial location. The highest concentration over the second decade was at a background location during winter (674 fg I-TEQ/m3). Winter observations are generally higher than those recorded in summer, as evident in an 8-year period of moderate PCDD/F levels (<250 fg I TEQ/m3, n = 143). PCDD/F congener profiles were identified has having less chlorinated PCDD/F, indicating the presence of nearby combustion sources at selected locations. More long-term sampling campaigns, combined with network optimization and integration into a meteorological model, can offer a tool for future PCDD/Fs control measures in not only Catalonia - but also applicable to other areas. PMID- 29602113 TI - A novel partial-denitrification strategy for post-anammox to effectively remove nitrogen from landfill leachate. AB - Anaerobic ammonia oxidation (anammox) has shown great promise for nitrogen removal in low C/N wastewater such as landfill leachate. However, 11% of NO3--N is stoichiometrically produced, which decreases the total nitrogen (TN) removal efficiency. In this study, a strategy for post anammox was developed to effectively remove TN from leachate. A tandem conversion of NO3--N to NO2--N (partial denitrification) was accomplished by supplying substrate for subsequent anammox, by supplementing the electron donor deficient condition. This process greatly improved NH4+-N and TN removal from leachate, reaching a 95% efficiency. Quantitative real-time polymerase chain reaction results showed that a high abundance of anammox bacteria, with a titer of 109 copy numbers/L, was enriched, accounting for 9.66% of the total bacterial community, and indicating the success of this novel strategy for the TN removal in leachate. PMID- 29602114 TI - Land subsidence in the Friuli Venezia Giulia coastal plain, Italy: 1992-2010 results from SAR-based interferometry. AB - Land subsidence is a concern in many coastal plains worldwide, particularly in the low-lying areas already facing sea level rise due to climate change, and much still needs to be done, with respect to both mapping land subsidence and gaining a comprehensive understanding of the relevant cause-effect relationships. Land subsidence of the northern coastal plain encompassing the Friuli Venezia Giulia (FVG) region in Italy, remains, to the authors' knowledge, poorly investigated. This coastland includes low-lying agricultural and urban areas and highly valuable lagoon environments, archaeological and touristic sites, and industrial zones. Here, we resolve land subsidence in the coastal plain between the Tagliamento River delta and the Isonzo River mouth over the period 1992-2010 using Envisat ASAR and ERS1/2 interferometric datasets. We identify a large variability of the land subsidence and a spatial gradient that ranges from less than 1mm/year in the high southwestern plain toward the littoral to more than 5mm/year close to the Tagliamento River delta. A comparison between the 2003-2010 and 1992-2000 sinking rates depicts quite similar behaviors of the process over the two time spans. The analysis indicates unclear correlations between ground movements and the typical driving mechanisms acting in the north Adriatic coastal plains, such as the variability of the morphological setting, the subsoil characteristics and the land use. We reason that multi-component mechanisms contribute to the observed image of the subsidence in the FVG coastland. Specifically, anthropogenic activities, e.g., groundwater exploitations, hydraulic reclamations and the development of newly built-up areas, are superposed to natural mechanisms related to the spatial variability of the subsoil characteristics, typical of transitional coastal environments. PMID- 29602115 TI - Decreased waterborne pathogenic bacteria in an urban aquifer related to intense shallow geothermal exploitation. AB - The implications of intensive use of shallow geothermal energy resources in shallow urban aquifers are still not known for waterborne pathogens relevant to human health. Firstly, we hypothesized that waterborne enteric pathogens would be relatively increased in heated groundwater plumes. To prove this, microbiological sampling of 31 piezometers covering the domain of an urban groundwater body affected by microbiological contamination and energetically exploited by 70 groundwater heat pump systems was performed. Mean differences of pathogenic bacteria contents between impacted and non-impacted monitoring points were assessed with a two-tailed independent Student's t-test or Mann-Whitney U and correlation coefficients were also calculated. Surprisingly, the results obtained revealed a significant and generalized decrease in waterborne pathogen contents in thermally impacted piezometers compared to that of non-impacted piezometers. This decrease is hypothesized to be caused by a heat shock to bacteria within the heat exchangers. The statistically significant negative correlations obtained between waterborne pathogen counts and temperature could be explained by the spatial distribution of the bacteria, finding that bacteria start to recover with increasing distance from the injection point. Also, different behavior groups fitting exponential regression models were found for the bacteria species studied, justified by the different presence and influence of several aquifer parameters and major, minor and trace elements studied, as well as the coexistence with other bacteria species. The results obtained from this work reinforce the concept of shallow geothermal resources as a clean energy source, as they could also provide the basis to control the pathogenic bacteria contents in groundwater bodies.
